At the special meeting, IGEN will ask you to vote on a proposal to adopt an agreement and plan of merger, or the merger agreement, pursuant to which Roche Holding Ltd will acquire IGEN and IGEN will simultaneously distribute the common stock of BioVeris Corporation to its stockholders. This transaction will resolve the long-running dispute between IGEN and Roche over ORIGEN(R) technology, IGEN's electrochemiluminescence technology used by Roche in its diagnostics business. The transaction will occur in the following steps: - IGEN will restructure its operations so that BioVeris Corporation, a newly formed, wholly-owned subsidiary of IGEN, will assume IGEN's biodefense, life science and industrial product lines as well as IGEN's opportunities in the clinical diagnostics and healthcare fields, and will own IGEN's intellectual property, IGEN's equity interest in Meso Scale Diagnostics, LLC., cash and certain other rights and licenses currently held by IGEN; and - A wholly-owned subsidiary of Roche will merge with and into IGEN, as a result of which IGEN will become a wholly-owned subsidiary of Roche and BioVeris will become an independent, publicly-traded company owned by IGEN stockholders. Simultaneously with the completion of the merger, certain ongoing commercial agreements between BioVeris and certain affiliates of Roche will become effective. If the merger agreement is adopted and the merger and related transactions are subsequently completed, you will be entitled to receive the following for each share of IGEN common stock you own: - $47.25 in cash, without interest; and - one share of BioVeris common stock. The receipt of the cash and BioVeris common stock will be fully taxable to you. IGEN's common stock is quoted on The NASDAQ National Market(R) under the symbol "IGEN." If the merger agreement is adopted and the merger and related transactions are subsequently completed, IGEN common stock will cease to be quoted on NASDAQ. BioVeris common stock has been approved for quotation on The NASDAQ National Market(R) under the symbol "BIOV." There is currently no public trading market for the shares of BioVeris common stock. The IGEN board of directors has carefully reviewed and considered the terms and conditions of the proposed merger and related transactions and has unanimously determined that the merger agreement is advisable and in the best interests of IGEN and its stockholders.

In addition, if the markets for BioVeris's products change or evolve in an unexpected manner, BioVeris's business could be materially adversely affected....... 25 BioVeris expects to rely on sales of the M-SERIES product family for a significant portion of its revenues, and a decline in sales of these products could cause adverse financial results and negatively affect BioVeris's business prospects.................. 25 BioVeris's competitors and potential competitors may have or develop diagnostic products and technologies that are more attractive than BioVeris's existing or future diagnostic products............................ 25 BioVeris has limited manufacturing experience, which puts it at a competitive disadvantage and could have a material adverse effect on BioVeris's business, financial condition and revenue....................... 26 i PAGE ---- BioVeris has limited manufacturing facilities for its products and BioVeris may not find additional facilities suitable for future growth, which could materially adversely affect its business and prospects............................................. 26 BioVeris has no experience selling, marketing or distributing clinical diagnostic products.

If BioVeris does not obtain the necessary clearances or approvals, its business prospects would suffer................................................ 34 BioVeris is subject to comprehensive government regulation, which may involve significant costs and may restrict its ability to conduct business.......... 35 BioVeris's business could be adversely affected by a negative audit by the U.S. government................. 35 Cost over-runs on contracts with the U.S. government could subject BioVeris to losses or adversely affect its future business................................... 36 Restrictions on healthcare costs and healthcare and insurance financing practices could limit demand for BioVeris's products, which would hurt BioVeris's business and business prospects....................... 36 Risks Relating to the Industry............................ 36 BioVeris is exposed to product liability risks that, if not adequately covered by insurance, may have a material adverse effect on its financial condition.... 36 Risks Relating to BioVeris Common Stock................... 36 BioVeris's executive officers and directors exercise significant influence over BioVeris and may have significant influence over the outcome of proposed corporate actions supported or opposed by other BioVeris stockholders................................. 36 Provisions in BioVeris's charter documents may discourage potential acquisitions of BioVeris, even those which the holders of a majority of BioVeris common stock may favor, which may adversely affect the market price of BioVeris common stock, reduce the likelihood of offers to acquire BioVeris and prevent changes in BioVeris's management...................... 37 There is currently no public trading market for the shares of BioVeris common stock, and there is no assurance that an active public trading market will develop............................................... 38 BioVeris's stock price may be volatile and could drop precipitously and unexpectedly........................ 38 BioVeris does not plan to pay any cash dividends on BioVeris common stock................................. 38 BioVeris may need to raise additional capital in the future and BioVeris may grant options or other equity-based awards to its executive officers, directors, employees and consultants, from time to time, either of which would result in dilution to BioVeris stockholders................................. 39 The Exon-Florio Act may inhibit potential acquisition bids, which may adversely affect the market price of BioVeris common stock................................. 39 THE SPECIAL MEETING......................................... 40 Date, Time and Place...................................... 40 Purpose of the Special Meeting............................ 40 Recommendations of the IGEN Board of Directors............ 40 Record Date;

These questions and answers do not, and are not intended to, address all of the information that may be important to you. You should read carefully this entire proxy statement/prospectus and the other documents to which IGEN and BioVeris refer you. Roche, when used in this proxy statement/prospectus, refers to Roche Holding Ltd or Roche Holding Ltd and its subsidiaries and affiliates, unless the context otherwise requires. Q: WHAT WILL HAPPEN TO IGEN AS A RESULT OF THE MERGER AND RELATED TRANSACTIONS? WHO IS BIOVERIS? A: As part of the restructuring of IGEN's operations prior to the merger, BioVeris Corporation, a newly formed, wholly-owned subsidiary of IGEN, will assume IGEN's biodefense, life sciences and industrial product lines as well as IGEN's opportunities in the clinical diagnostics and healthcare fields, and will own IGEN's intellectual property, IGEN's equity interest in Meso Scale Diagnostics, LLC., a company formed by IGEN and Meso Scale Technologies, LLC., which is a company established and wholly-owned by a son of IGEN's and BioVeris's chairman and chief executive officer, cash and certain other rights and licenses currently held by IGEN. IGEN will retain IGEN's remaining businesses, including worldwide, non-exclusive, fully-paid, royalty-free rights to ORIGEN(R) technology, IGEN's electrochemiluminescence, or ECL, technology in the human in vitro diagnostics field. As a result of the merger, IGEN will become a wholly-owned subsidiary of Roche. Upon completion of the merger and related transactions, BioVeris will become an independent, publicly-traded company owned by IGEN stockholders. BioVeris will have the assets described above as well as certain ongoing commercial agreements with affiliates of Roche. Q: WHAT WILL I RECEIVE IN THE MERGER AND RELATED TRANSACTIONS? A: Upon completion of the merger and related transactions, each outstanding share of IGEN common stock (other than shares held by stockholders who validly exercise appraisal rights) will be converted into the right to receive: - $47.25 in cash, without interest; and - one share of BioVeris common stock. Q: WHAT ARE THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER AND RELATED TRANSACTIONS TO ME? A: The receipt of cash and BioVeris common stock pursuant to the merger should be treated as a single integrated transaction for U.S. Federal income tax purposes. In such case, generally speaking, each IGEN stockholder will recognize gain or loss equal to the difference, if any, between: - the sum of the amount of cash received plus the fair market value of the BioVeris common stock received (valued at the time of the distribution of shares of BioVeris common stock); and - such stockholder's adjusted tax basis in its IGEN common stock immediately prior to the merger. Such gain or loss will generally be capital gain or loss, and generally will be long-term capital gain or loss if the IGEN common stock exchanged in the merger had been held for more than one year at the time of the merger. The tax consequences of the merger and related transactions are complex and may vary depending on your particular circumstances. In addition, the U.S. Internal Revenue Service could contend, and a court might agree, that the merger and related transactions should be characterized in a manner different than that described above. You should carefully read the full section of this proxy statement/ prospectus regarding the U.S. Federal income tax consequences of the merger and related transactions and the risk factor "The amount and character of income, gain or loss you may recognize as a result of the merger and related transactions cannot be precisely determined," and are urged to consult your own tax advisors concerning the tax consequences to you of the merger and 1 related transactions, including any applicable Federal, state, local and foreign tax consequences. Q: WHAT DOES THE IGEN BOARD OF DIRECTORS RECOMMEND? A: The IGEN board of directors unanimously recommends that IGEN stockholders vote "FOR" the adoption of the merger agreement and "FOR" the approval of the proposed BioVeris 2003 stock incentive plan described in this proxy statement/prospectus. Q: WHAT STOCKHOLDER APPROVALS ARE NEEDED TO ADOPT THE MERGER AGREEMENT? A: The adoption of the merger agreement requires the affirmative vote of stockholders holding a majority of the shares of IGEN common stock outstanding on the record date for the special meeting. Q: WHAT STOCKHOLDER APPROVALS ARE NEEDED TO APPROVE THE PROPOSED BIOVERIS 2003 STOCK INCENTIVE PLAN? A: The approval of the proposed BioVeris 2003 stock incentive plan requires the vote of a majority of the votes cast, excluding abstentions, at the special meeting at which a quorum is present. Q: WHAT DO I NEED TO DO NOW? A: After carefully reading and considering the information contained in this proxy statement/prospectus, please complete, sign, date and return your proxy card in the enclosed postage-paid return envelope so that your shares may be represented at the special meeting of IGEN stockholders. You may also submit your proxy by telephone or over the Internet by following the instructions on your proxy card. Q: WHAT IF I DO NOT VOTE? A: If you fail to either submit a proxy or vote in person, it will have the same effect as a vote against the adoption of the merger agreement because the required vote of IGEN stockholders is based upon the number of outstanding shares of IGEN common stock, rather than upon the number of shares actually voted. Failure to either submit a proxy or vote in person will have no effect on the approval of the proposed BioVeris 2003 stock incentive plan. If you sign, date and return your proxy card and do not indicate how you want to vote, IGEN will count your proxy as a vote in favor of the adoption of the merger agreement and a vote in favor of the approval of the proposed BioVeris 2003 stock incentive plan. If you sign, date and return your proxy card and abstain from voting, it will have the same effect as a vote against the adoption of the merger agreement but will have no effect on the approval of the proposed BioVeris 2003 stock incentive plan. Q: CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD? A: Yes. You can change your vote at any time before your proxy is voted at the special meeting. You can do this in one of three ways. - First, you can send a written notice stating that you would like to revoke your proxy. - Second, you can complete and submit a new proxy bearing a later date. If you choose either of these two methods, you must submit your notice of revocation or your new proxy before the special meeting to IGEN at 16020 Industrial Drive, Gaithersburg, MD 20877, Attention: Secretary. You may also submit your new proxy by telephone or over the Internet. If your shares are held in an account at a brokerage firm or a bank, you should contact your broker or bank to change your vote. - Third, if you are a holder of record as of the close of business on December 18, 2003, the record date for the special meeting, you can attend the special meeting and vote your shares in person. Attendance at the special meeting will not in and of itself constitute revocation of a proxy. Q: IF MY IGEN SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY SHARES FOR ME? A: Your broker will vote your shares of IGEN common stock only if you provide instructions on how to vote. You should follow the directions provided by your broker regarding how to instruct your broker to vote your shares. Without instructions, your shares will not be voted, which will have the same effect as a vote against the adoption of the merger 2 agreement and will have no effect on the approval of the proposed BioVeris 2003 stock incentive plan. Q: SHOULD I SEND IN MY STOCK CERTIFICATES NOW? A: No. After the merger is completed, you will be sent a transmittal form with instructions for the surrender of IGEN common stock certificates. Please do not send in your stock certificates with your proxy card. Q: AM I ENTITLED TO APPRAISAL RIGHTS? A: Yes, if you do not vote in favor of adoption of the merger agreement, you may exercise your right under Delaware law to demand appraisal of your shares of IGEN common stock and to receive payment in cash for the fair value of your shares as determined by the Delaware Court of Chancery. The fair value of shares of IGEN common stock as determined by the Delaware Court of Chancery may be more or less than or the same as the value of the merger consideration to be paid to IGEN stockholders who do not exercise appraisal rights. You should carefully read the full section in this proxy statement/prospectus entitled "The Merger and Related Transactions -- Appraisal Rights" and the copy of the relevant provision of Delaware law attached as Annex 17 to this proxy statement/prospectus for a more complete description of appraisal rights and the procedures to exercise your appraisal rights. Q: WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED? A: IGEN and BioVeris are working to complete the merger as quickly as possible. If the merger agreement is adopted by IGEN stockholders, IGEN and BioVeris expect to complete the merger shortly after the special meeting. Q: HOW WILL I KNOW IF THE MERGER AND RELATED TRANSACTIONS HAVE OCCURRED? A: If the merger and related transactions occur, BioVeris will make a public announcement and you will receive notice by mail. Q: ARE THERE ANY IMPORTANT RISKS ABOUT THE MERGER AND RELATED TRANSACTIONS OF WHICH I SHOULD BE AWARE? A: Yes, there are important risks involved. Before making any decision on how to vote and whether to vote, IGEN and BioVeris encourage you to read carefully and in its entirety the "Risk Factors" section of this proxy statement/prospectus that begins on page 18.

THE COMPANIES AND THE LITIGATION (PAGE 43) ROCHE HOLDING LTD Grenzacherstrasse 124, CH-4070 Basel, Switzerland Telephone: (+41) 61-688-8880 Roche is one of the world's leading innovation-driven healthcare groups. Roche's core businesses are pharmaceuticals and diagnostics. Roche is one of the world's leading providers of diagnostic systems, one of the leading suppliers of pharmaceuticals for cancer and a leader in virology and transplantation. As a supplier of products and services for the prevention, diagnosis and treatment of disease, Roche contributes on a broad range of fronts to improving people's health and quality of life. Roche employs approximately 65,000 people in 150 countries around the world. IGEN INTERNATIONAL, INC. 16020 Industrial Drive Gaithersburg, MD 20877 Telephone: (301) 869-9800 IGEN and its licensees develop, manufacture and market products based on IGEN's ECL technology. IGEN believes that its ECL technology, which detects and measures biological substances, offers significant advantages over competing detection and measurement methods by providing a unique combination of speed, sensitivity, flexibility and throughput in a single technology platform. ECL technology is incorporated into IGEN's and its licensees' instrument systems and reagents, which are the biological and chemical compounds that are used to perform a test, or assay, on such instrument systems. BIOVERIS CORPORATION 16020 Industrial Drive Gaithersburg, MD 20877 Telephone: (301) 869-9800 BioVeris is a newly formed, wholly-owned subsidiary of IGEN. As part of the restructuring of IGEN's operations prior to the merger, BioVeris will assume IGEN's biodefense, life sciences and industrial product lines, as well as IGEN's opportunities in the clinical diagnostics and healthcare fields, and will own IGEN's intellectual property, IGEN's equity interest in Meso Scale Diagnostics, LLC., which is referred to in this proxy statement/prospectus as MSD, a company formed by IGEN and Meso Scale Technologies, LLC., which is referred to in this proxy statement/prospectus as MST, which is a company established and wholly-owned by a son of IGEN's and BioVeris's chairman and chief executive officer, cash and certain other rights and licenses currently held by IGEN. Simultaneously with the completion of the merger, certain ongoing commercial agreements between BioVeris and certain affiliates of Roche will become effective. BioVeris's strategy is based on the direct development and sale of its products utilizing its technologies, while at the same time entering into collaborations with third parties that can assist BioVeris in its product development, manufacturing and marketing efforts. Key elements of BioVeris's strategy are to: - pursue collaborative relationships to accelerate new product development and enhance global manufacturing and marketing capabilities; - establish leadership positions in emerging markets; and - develop and market product line extensions and an expanded menu of assays. 4 THE LITIGATION Since 1997, IGEN and Roche have been involved in a lawsuit in the Southern Division of the U.S. District Court for the District of Maryland, which is referred to in this proxy statement/prospectus as the District Court, relating to, among other things, IGEN's ability to terminate a license agreement for ECL technology that was granted in 1992 to a company that became a subsidiary of Roche. On July 9, 2003, the U.S. Court of Appeals for the Fourth Circuit, which is referred to in this proxy statement/prospectus as the Appellate Court, among other things, affirmed IGEN's right to terminate the license while vacating the $400 million punitive damage award against the subsidiary of Roche and reversing $86.8 million of the compensatory damage award against the subsidiary of Roche. This lawsuit is referred to in this proxy statement/ prospectus as the Roche litigation. In addition, on July 9, 2003, IGEN sent a notice to the subsidiary of Roche confirming termination of the license and filed patent infringement lawsuits against the subsidiary in Maryland and in Germany. These lawsuits have been stayed by agreement of the parties pending completion of the merger. GENERAL RECOMMENDATIONS OF THE IGEN BOARD OF DIRECTORS (PAGE 40) The IGEN board of directors has unanimously determined that the merger agreement is advisable and in the best interests of IGEN and its stockholders, unanimously approved the merger agreement and unanimously recommends that IGEN stockholders vote "FOR" the adoption of the merger agreement. You are not being asked to vote on the restructuring of IGEN's operations. To review the background to and reasons for the merger, as well as certain risks related to the merger, see "The Merger and Related Transactions" on page 43 and "Risk Factors -- Risks Relating to the Merger and Related Transactions" on page 18. The IGEN board of directors also unanimously recommends that IGEN stockholders vote "FOR" the approval of the proposed BioVeris 2003 stock incentive plan. OPINION OF LEHMAN BROTHERS (PAGE 57) In deciding to approve the merger, the IGEN board of directors considered the opinion of Lehman Brothers, its financial advisor in connection with the merger, that, based upon and subject to the matters described in the opinion, as of July 24, 2003 (the date of the merger agreement), from a financial point of view, the consideration to be received by IGEN stockholders in the merger was fair to such stockholders. The full text of the written opinion of Lehman Brothers, which sets forth the assumptions made, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex 15. The opinion is not a recommendation as to how you should vote your shares. You are urged to read this opinion carefully and in its entirety. INTERESTS OF IGEN'S DIRECTORS AND EXECUTIVE OFFICERS IN THE MERGER AND RELATED TRANSACTIONS (PAGE 62) In considering the recommendation of the IGEN board of directors that you vote "FOR" the adoption of the merger agreement, you should be aware that the members of the IGEN board of directors and IGEN's executive officers have personal interests in the merger and related transactions that are or may be different from, or in addition to, the interests of other IGEN stockholders. These interests include: - accelerated vesting of options to acquire 307,383 shares of IGEN common stock, in the aggregate, which would entitle the members of the IGEN board of directors and IGEN's executive officers to receive, in the aggregate, approximately $5.5 million in cash and 307,383 shares of BioVeris common stock; - continued rights to indemnification and exculpation from liabilities for certain acts or omissions; - continued coverage under directors' and officers' liability insurance with limits of $30 million for claims arising from or related to facts or events which occurred at or prior to the completion of the merger; - continued employment of IGEN's three executive officers in similar positions with BioVeris for annual salaries anticipated to be initially comparable to the current sala- 5 ries being received from IGEN, which is approximately $1,011,000 in the aggregate; - receipt by Messrs. Samuel Wohlstadter, Richard Massey and George Migausky of a transaction bonus of $1,278,000, $450,000 and $450,000, respectively, simultaneous with completion of the merger and related transactions; and - appointment of the members of the IGEN board of directors (other than Mr. Richard Cass) to the BioVeris board of directors, with each non-employee director entitled to receive a $10,000 annual retainer, a $1,000 attendance fee per meeting attended, the options discussed in the next paragraph and additional fees for serving on committees of the BioVeris board of directors, which represent an increase from the compensation non-employee directors were entitled to receive from IGEN. Furthermore, if approved by IGEN stockholders, BioVeris will adopt the BioVeris 2003 stock incentive plan pursuant to which each of BioVeris's non-employee directors will automatically receive annual grants of options to purchase 4,000 shares of BioVeris common stock and BioVeris's executive officers will be eligible to receive option grants or other equity-based awards. In addition, any person who is appointed or elected as a non-employee director of BioVeris will automatically receive grants of options to purchase 4,000 shares of BioVeris common stock. In addition, as part of the merger and related transactions: - BioVeris has agreed to make a final capital contribution of $37.5 million (of which any amount in excess of $30 million will be funded by Mr. Samuel Wohlstadter, IGEN's and BioVeris's chairman and chief executive officer, through the purchase of shares of BioVeris series B preferred stock that economically mirror the class C interests in MSD to be held by BioVeris) to MSD, a company formed by IGEN and MST, which is a company established and wholly-owned by Mr. Jacob Wohlstadter, a son of Mr. Samuel Wohlstadter; - BioVeris has agreed to assume IGEN's obligations under a letter agreement dated August 15, 2001, between MSD, MST and Mr. Jacob Wohlstadter, which together are referred to in this proxy statement/prospectus as the indemnified parties, and IGEN. Pursuant to the letter agreement, IGEN agreed to fund the reasonable ongoing legal fees and related charges and costs incurred by the indemnified parties arising out of or related to the Roche litigation, including any legal fees and related charges and costs arising out of or related to any of IGEN's ongoing negotiations regarding, and the settlement of, the Roche litigation. MSD has submitted to IGEN invoices for legal fees and expenses for the period from March 1, 2003 through September 30, 2003 in the amount of approximately $1.3 million, of which IGEN has paid approximately $423,000, which the joint venture oversight committee of the IGEN board of directors, or the JVOC, believes is the amount IGEN is obligated to pay under the terms of the letter agreement for the period from March 1, 2003 through September 30, 2003. The indemnified parties, through their counsel, have not accepted the JVOC's determination, and the JVOC believes it is likely that the indemnified parties will continue to seek reimbursement for the balance of the $1.3 million claimed, which approximates $877,000. In addition, MSD submitted to IGEN invoices for legal fees and expenses of approximately $26,000 for October 2003 and approximately $21,000 for November 2003. The JVOC has not yet made any determination regarding MSD's claims for October and November 2003. The JVOC expects that the indemnified parties will submit claims for reimbursement of additional expenses for the period from December 1, 2003 through the completion of the merger; - BioVeris has agreed to assume IGEN's obligations under Mr. Jacob Wohlstadter's employment agreement, consulting agreement and indemnification agreement, pursuant to which Mr. Jacob Wohlstadter will be entitled to receive an annual salary of $250,000 plus bonus and benefits from MSD, compensation from BioVeris for consulting services, if any, that may be provided to and at the request of BioVeris 6 and indemnification by BioVeris against claims arising from services rendered to BioVeris; and - BioVeris has agreed to assume all of IGEN's current agreements and understandings with companies controlled by Mr. Samuel Wohlstadter, including certain shared services agreements and license agreements. Also, upon completion of the merger, the MSD joint venture agreement will expire and MSD will have the right to purchase BioVeris's entire interest in MSD for a purchase price equal to fair market value determined in accordance with the MSD joint venture agreement, less a discount factor. The discount factor will be equal to 7.5% if the MSD joint venture agreement expires upon the completion of the merger and has not been otherwise terminated before completion. In the event MSD or MST elects to purchase BioVeris's interest in MSD, BioVeris will only be entitled to receive the purchase price payable over time in installments equal to the sum of 5% of MSD net sales, as determined in accordance with the MSD agreements, and 20% of the net proceeds realized from certain third-party financings in accordance with the MSD agreements. In the event such future net sales of MSD or third-party financings do not materialize, BioVeris will not receive any payments from MSD or MST, as the case may be, for the purchase of BioVeris's interest in MSD. For a more complete description, see "The Merger and Related Transactions -- Interests of IGEN's Directors and Executive Officers in the Merger and Related Transactions" and "Certain Relationships and Related Party Transactions." In addition, in considering the recommendation of the IGEN board of directors that you vote "FOR" the approval of the proposed BioVeris 2003 stock incentive plan, you should be aware that the members of the IGEN board of directors and IGEN's executive officers have personal interests in the approval of the BioVeris 2003 stock incentive plan that are or may be different from, or in addition to, the interests of others IGEN stockholders, including being eligible to receive option grants or other equity-based awards under the BioVeris 2003 stock incentive plan if adopted. COMPARISON OF RIGHTS OF COMMON STOCKHOLDERS OF BIOVERIS AND IGEN (PAGES 181 AND 186) IGEN stockholders, whose rights are currently governed by IGEN's certificate of incorporation and by-laws and Delaware law, will, upon completion of the merger, become BioVeris stockholders and their rights with respect to their ownership of BioVeris common stock will be governed by BioVeris's certificate of incorporation and by-laws, which are similar to IGEN's certificate of incorporation and by-laws, and Delaware law. In addition, BioVeris intends to adopt prior to the completion of the merger and related transactions a stockholder rights agreement, pursuant to which shares of BioVeris preferred stock will be designated as BioVeris series A participating cumulative preferred stock for issuance in connection with the exercise of the right attached to each share of BioVeris common stock. For a more complete description, see "Description of BioVeris Capital Stock" and "Comparison of Rights of Common Stockholders of BioVeris and IGEN."

On the record date for the special meeting, 24,986,546 shares of IGEN common stock were issued and outstanding and entitled to vote at the special meeting. You will have one vote on each matter submitted to a vote at the special meeting for each share of IGEN common stock that you owned on the record date for the special meeting. VOTES REQUIRED (PAGE 40) The adoption of the merger agreement requires the affirmative vote of stockholders holding 7 a majority of the shares of IGEN common stock outstanding on the record date for the special meeting. The approval of the proposed BioVeris 2003 stock incentive plan requires the vote of a majority of the votes cast, excluding abstentions, at the special meeting at which a quorum is present. ANTITRUST MATTERS (PAGE 70) United States antitrust laws prohibit Roche and IGEN from completing the merger until they have furnished certain information and materials to the Antitrust Division of the Department of Justice and the Federal Trade Commission pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the applicable waiting period has expired or been terminated. On September 5, 2003, Roche and IGEN each filed the required notification and report forms with the Antitrust Division and the Federal Trade Commission and Roche requested early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. Early termination of the required waiting period was granted effective on September 29, 2003. For a more complete description, see "The Merger and Related Transactions -- Antitrust Matters." APPRAISAL RIGHTS (PAGE 70) IGEN stockholders who do not vote in favor of adoption of the merger agreement have the right under Delaware law to demand appraisal of their shares of IGEN common stock and to receive payment in cash for the fair value of their shares as determined by the Delaware Court of Chancery. The fair value of shares of IGEN common stock as determined by the Delaware Court of Chancery may be more or less than or the same as the value of the merger consideration to be paid to IGEN stockholders who do not exercise appraisal rights. To exercise appraisal rights, IGEN stockholders must not vote in favor of adoption of the merger agreement and must precisely follow specific procedures, or the appraisal rights may be lost. For a description of these procedures, see "The Merger and Related Transactions -- Appraisal Rights" and the copy of the relevant provision of Delaware law attached as Annex 17 to this proxy statement/prospectus.

THE MERGER AND RELATED TRANSACTIONS (PAGE 45) The merger agreement is attached as Annex 2 to this proxy statement/prospectus. IGEN and BioVeris encourage you to read the merger agreement carefully because it is one of the principal documents governing the merger and related transactions. THE AGREEMENTS Simultaneously with the execution and delivery of the merger agreement, IGEN, BioVeris, Roche and certain of Roche's affiliates, including 66 Acquisition Corporation II, which is referred to in this proxy statement/prospectus as the merger sub, and Roche Diagnostics GmbH, which is referred to in this proxy statement/prospectus as Roche Diagnostics, IGEN LS LLC, which is referred to in this proxy statement/prospectus as the license sub, Mr. Samuel Wohlstadter, Mr. Jacob Wohlstadter, MSD, MST, which is a company established and wholly-owned by Mr. Jacob Wohlstadter, and JW Consulting Services L.L.C., also a company established and wholly-owned by Mr. Jacob Wohlstadter, also entered into the following agreements: - the restructuring agreement, attached as Annex 1; - the post-closing covenants agreement, attached as Annex 3; - the tax allocation agreement, attached as Annex 4; - the ongoing litigation agreement, attached as Annex 5; - the global consent and agreement, attached as Annex 6; - the MSD letter agreement, attached as Annex 7; 8 - the BioVeris preferred stock purchase agreement, attached as Annex 8; - the release and agreement, attached as Annex 9; - the improvements license agreement, attached as Annex 11; - the covenants not to sue, attached as Annex 12; - the PCR product license agreement, attached as Annex 13; and - the PCR services license agreement, attached as Annex 14. In addition, simultaneously with the execution and delivery of the merger agreement, IGEN and the license sub entered into the license agreement, attached as Annex 10. The restructuring agreement, the post-closing covenants agreement, the tax allocation agreement, the ongoing litigation agreement, the global consent and agreement and the release and agreement are referred to in this proxy statement/prospectus as the related transaction agreements. The improvements license agreement, the covenants not to sue, the license agreement, the PCR product license agreement and the PCR services license agreement are referred to in this proxy statement/prospectus as the ongoing commercial agreements. THE RESTRUCTURING AND THE LICENSE AGREEMENT(PAGES 74 AND 104) Pursuant to the restructuring agreement between IGEN and BioVeris, prior to the completion of the merger, IGEN will transfer certain of its assets and liabilities to BioVeris, which is referred to in this proxy statement/prospectus as the restructuring. As part of the restructuring, BioVeris, a newly formed, wholly-owned subsidiary of IGEN, will assume IGEN's biodefense, life sciences and industrial product lines as well as IGEN's opportunities in the clinical diagnostics and healthcare fields, and will own IGEN's intellectual property, IGEN's equity interest in MSD, a company formed by IGEN and MST, which is a company established and wholly-owned by Mr. Jacob Wohlstadter, a son of IGEN's and BioVeris's chairman and chief executive officer, cash, and certain other rights and licenses currently held by IGEN. IGEN and the license sub will retain IGEN's remaining businesses, including worldwide, non-exclusive, fully-paid, royalty-free rights to ECL technology in the human in vitro diagnostics field described below. Upon completion of the merger and related transactions, BioVeris will become an independent, publicly-traded company owned by IGEN stockholders. BioVeris will have the assets described above as well as certain ongoing commercial agreements with affiliates of Roche. Following completion of the merger, IGEN and Roche, on the one hand, and BioVeris, on the other hand, will indemnify each other with respect to various losses, damages, claims and liabilities, including those arising out of IGEN's and BioVeris's respective businesses. Under the license agreement, IGEN and its affiliates granted to the license sub, effective simultaneously with the completion of the merger, a worldwide, non-exclusive, fully-paid, royalty-free license under patents and technology that relate to detection methods and systems which employ ECL technology, but specifically excluding technology related to gene amplification or compounds composed of or capable of binding with nucleotides, which collectively are referred to in this proxy statement/prospectus as the licensed ECL technology. The license may be used only in a specific field, generally described in this proxy statement/prospectus as the human in vitro diagnostics field, to develop, make, reproduce, modify, use, sell and otherwise commercially exploit specified products. The license sub will remain a subsidiary of IGEN, and therefore will be a subsidiary of Roche, following the merger. IGEN's rights, as licensor under the license agreement, will be transferred to BioVeris as part of the restructuring. ACCOUNTING TREATMENT OF THE RESTRUCTURING (PAGE 66) The transfer of certain assets and liabilities by IGEN to BioVeris will be accounted for based upon the authoritative guidance governing the distribution of nonmonetary assets to an entity under "common control." As such, IGEN's historical cost basis in the assets and liabilities transferred will become the initial recorded value of these assets and liabilities by BioVeris upon completion of the restructuring. 9 THE MERGER (PAGE 78) At the completion of the merger, the merger sub, a wholly-owned subsidiary of Roche, will merge with and into IGEN. IGEN will survive the merger as a wholly-owned subsidiary of Roche. Upon completion of the merger and related transactions, each outstanding share of IGEN common stock (other than shares held by stockholders who validly exercise appraisal rights) will be converted into the right to receive: - $47.25 in cash, without interest; and - one share of BioVeris common stock. CONDITIONS TO THE COMPLETION OF THE MERGER (PAGE 78) Roche and IGEN will complete the merger only if they satisfy, or in some cases, waive, several conditions, including the following: - the adoption of the merger agreement by IGEN stockholders; - the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976; - the absence of any legal restraint or prohibition preventing the completion of the merger; - the registration statement of which this proxy statement/prospectus forms a part not being the subject of any stop order or proceedings seeking a stop order; - certain consents by MSD or agreements to which MSD is party, which are more fully described below, must be in full force and effect and must not have been amended or modified without the consent of Roche and IGEN; and - the release and agreement, among IGEN, BioVeris and certain companies owned or controlled by Mr. Samuel Wohlstadter, which is more fully described below, must be in full force and effect and must not have been amended or modified without the consent of Roche, IGEN and BioVeris. Roche's obligation to complete the merger is subject to satisfaction or waiver of additional conditions, including the following: - the accuracy of IGEN's representations and warranties in the merger agreement, subject in some instances as to materiality or transaction material adverse effect; - the performance by IGEN of its obligations under the merger agreement, subject in some instances as to materiality or transaction material adverse effect; - the completion by IGEN of the restructuring; - the payment in full by IGEN of its 8.5% senior secured notes; and - the receipt by IGEN of a solvency opinion from an independent solvency firm of nationally recognized reputation substantially to the effect that BioVeris will not be insolvent after giving effect to the merger and related transactions. A "transaction material adverse effect" means any change, effect, occurrence, condition, development or any state of facts, except those arising out of, related to, or in connection with, the Roche litigation or the patent infringement litigation against Roche Diagnostics in Maryland and Germany or principally attributable to the economy in general or BioVeris's industry in general, that - renders IGEN insolvent immediately prior to completion of the merger or - after giving effect to the merger and related transactions (1) results in or would reasonably be expected to result in a loss by IGEN or BioVeris of certain licenses or intellectual property rights, in the case of each, that materially impairs the legal right of Roche Diagnostics and its affiliates to make, have made, use, sell, place or otherwise commercialize products using the licensed ECL technology or (2) renders BioVeris insolvent at the time of the merger. IGEN's obligation to complete the merger is also subject to satisfaction or waiver of additional conditions, including the following: - the accuracy of Roche's and the merger sub's representations and warranties in the 10 merger agreement, subject in some instances as to materiality; - the performance by Roche and the merger sub in all material respects of their obligations under the merger agreement; - BioVeris's common stock must have been approved for listing on a national securities exchange or approved for quotation on The NASDAQ Stock Market(R); and - Roche having loaned to IGEN $214 million minus the amount of cash received by IGEN from the exercise of IGEN stock options and warrants from the date of the merger agreement to the date that is two business days prior to the completion of the merger (this loan will remain IGEN's obligation after completion of the merger). For a more complete description, see "The Merger Agreement -- Conditions." TERMINATION OF THE MERGER AGREEMENT; TERMINATION FEE; FEES AND EXPENSES (PAGES 82 AND 83) The merger agreement contains provisions addressing the circumstances under which Roche or IGEN may terminate the merger agreement. In addition, the merger agreement provides that, in several circumstances, IGEN may be required to pay Roche a termination fee of $26.6 million, including if IGEN terminates the merger agreement to accept a superior proposal. In addition, if the merger agreement is terminated in specified circumstances, IGEN is required to reimburse Roche for all of its reasonable expenses in connection with the merger agreement, the related transaction agreements, the ongoing commercial agreements and the merger and related transactions, subject to a $5 million cap. For a more complete description, see "The Merger Agreement -- Termination of the Merger Agreement" and "The Merger Agreement -- Fees and Expenses." Except if the merger agreement is terminated in specified circumstances, each of Roche and IGEN, will pay its own fees and expenses in connection with the merger and related transactions. IGEN will either pay its expenses prior to the completion of the merger or such expenses will be assumed by BioVeris pursuant to the restructuring agreement. POST-CLOSING COVENANTS AGREEMENT (PAGE 90) The post-closing covenants agreement among Roche, IGEN and BioVeris governs certain relationships between BioVeris and Roche following completion of the merger, including, among other things: - indemnification by BioVeris and Roche of each other with respect to certain matters; - an agreement by Roche not to solicit BioVeris's employees; - continued indemnification of IGEN's current or former directors and officers; - continued coverage under directors' and officers' liability insurance for claims arising from or related to facts or events which occurred at or prior to the completion of the merger; - a continuing standstill agreement; - limitations on certain claims by BioVeris, Roche and their respective affiliates against each other or their respective affiliates; and - mutual releases between Roche, on the one hand, and BioVeris, on the other hand, of certain liabilities. TAX ALLOCATION AGREEMENT (PAGE 94) The tax allocation agreement among Roche, the merger sub, IGEN and BioVeris allocates responsibility among the parties for preparing and filing tax returns and paying taxes. This agreement also provides for BioVeris to make a payment to IGEN of up to $20 million. The amount of the payment will depend upon the average of the high and the low trading prices of BioVeris common stock on the first day of trading after the completion of the merger. A payment will be due if such average is at least approximately $11.41 per share and the maximum payment will be due if such average exceeds approximately $13.28, in each case based on the assumption that BioVeris will have $205 million in cash and cash equivalents immediately after completion of the merger and prior to making any payments due pursuant to the related transaction agreements, the ongoing commercial agreements or the MSD letter agreement. The distribution of BioVeris stock will be a taxable transaction for IGEN and the purpose of this payment is for BioVeris to 11 share in a portion of the tax that IGEN might incur as a result of that distribution. The formula, which takes into account the expected approximate tax basis and tax rate that would be used in IGEN's calculation of its tax, was negotiated by Roche and IGEN as part of the overall negotiation of the merger. ONGOING LITIGATION AGREEMENT (PAGE 95) The ongoing litigation agreement among IGEN and certain affiliates of Roche provides for all litigation between IGEN and Roche to be suspended pending the completion of the merger. As a result, on July 25, 2003, Roche Diagnostics filed a motion to withdraw its petition to the Appellate Court for rehearing of the Roche litigation and on August 1, 2003, the Appellate Court granted the motion. The Appellate Court returned the matter to the District Court on August 8, 2003 for entry of a final order consistent with the Appellate Court ruling. The parties have not made any filing with the District Court, and the District Court has not issued any further orders in this case. In connection with the patent infringement litigation in Maryland, on August 1, 2003, IGEN and Roche Diagnostics filed a joint motion to stay, which was promptly granted by the court. In connection with the patent infringement litigation in Germany, on August 8, 2003, IGEN and Roche Diagnostics jointly filed the required documents to obtain a stay of the patent infringement litigation in Germany. No further action is required of the parties or the court in order to stay the proceedings. In addition, in the ongoing litigation agreement Roche agreed to pay IGEN a monthly fee of $5 million as partial consideration for the ongoing litigation agreement. GLOBAL CONSENT AND AGREEMENT (PAGE 98) The global consent and agreement among BioVeris, IGEN, Roche, MSD, MST, Mr. Jacob Wohlstadter and JW Consulting Services, L.L.C., sets forth, among other things, the consent of MSD, MST, Mr. Jacob Wohlstadter and JW Consulting Services, L.L.C. to the transfer of IGEN's interest in MSD to BioVeris and grants all waivers and consents of such parties necessary to permit the completion of the merger and related transactions and the performance by IGEN, BioVeris and each consenting party of their obligations under the merger agreement, the related transaction agreements and the ongoing commercial agreements. MSD LETTER AGREEMENT AND BIOVERIS PREFERRED STOCK PURCHASE AGREEMENT (PAGE 100 AND 101) Pursuant to the MSD letter agreement among IGEN, BioVeris, MSD, MST, Mr. Jacob Wohlstadter and JW Consulting Services, L.L.C., a company established and wholly-owned by Mr. Jacob Wohlstadter, BioVeris agreed to make a final capital contribution of $37.5 million to MSD, a company formed by IGEN and MST, which is a company established and wholly-owned by Mr. Jacob Wohlstadter, a son of Mr. Samuel Wohlstadter, IGEN's and BioVeris's chairman and chief executive officer. Of the $37.5 million, Mr. Samuel Wohlstadter will fund any amount in excess of $30 million through the purchase of shares of BioVeris preferred stock that economically mirror the class C interests in MSD to be held by BioVeris, as specified in the BioVeris preferred stock purchase agreement between Mr. Samuel Wohlstadter and BioVeris. In addition, IGEN and MST agreed to extend the expiration of the terms of the MSD joint venture agreement until the later of - November 30, 2003, or - the earlier of the completion of the merger or the termination of the merger agreement in accordance with its terms. RELEASE AND AGREEMENT (PAGE 102) Hyperion Catalysis International, Wellstat Biologics Corporation, Wellstat Therapeutics Corporation, Proteinix Corporation and Integrated Chemical Synthesizers, Inc., which are collectively referred to in this proxy statement/prospectus as the related companies, have entered into a release and agreement with BioVeris and IGEN, pursuant to which, among other things, IGEN and the related companies agreed to release each other from any liabilities or obligations arising out of their relationship or any of their agreements and understandings, and that all such agreements and understandings would be transferred to BioVeris. IMPROVEMENTS LICENSE AGREEMENT (PAGE 106) Under the improvements license agreement entered into simultaneously with the execution 12 and delivery of the merger agreement, Roche Diagnostics and its affiliates granted to IGEN, effective simultaneously with the completion of the merger, an irrevocable, worldwide, non-exclusive, fully-paid, royalty-free, perpetual license under certain patents covering and technologies based on: - Roche Diagnostics' ECL instruments and all aspects of ECL assays developed prior to the completion of the merger; - certain polymerase chain reaction, or PCR, technology; or - all aspects of ECL technology and robotics used or developed by Roche Diagnostics or its affiliates prior to the completion of the merger to be used in performing ECL testing (other than certain antibodies, antigens and certain reagents). The license may be used to develop, make, reproduce, modify, use, sell and otherwise commercially exploit any product or service based on ECL technology. IGEN has agreed, however, that the license does not permit it to manufacture or sell ECL instruments that both meet certain specifications and use specific intellectual property in the field defined in the improvements license agreement. IGEN has further agreed that the license does not permit it to develop, use, manufacture or sell ECL assays that contain labeling that make them useable on: - ECL instruments manufactured, sold or placed by Roche Diagnostics or its licensees or resellers in the field defined in the improvements license agreement; or - ECL instruments that meet certain specifications, use specific intellectual property and are manufactured by IGEN, its affiliates, sublicensees or authorized third parties which are used in the field defined in the improvements license agreement. In addition, IGEN is licensed to use certain Hitachi intellectual property rights to make any product or service based on ECL technology, but only outside the field defined in the improvements license agreement, which is generally human in vitro diagnostics. IGEN's interests under this agreement will be assigned to BioVeris as part of the restructuring. COVENANTS NOT TO SUE (PAGE 108) Under the covenants not to sue entered into simultaneously with the execution and delivery of the merger agreement, each of Roche, Roche Diagnostics and the license sub agreed on behalf of themselves and their respective affiliates that, effective simultaneously with the completion of the merger, they would not, directly or indirectly, pursue any claim against BioVeris, MSD or MST or any of their respective affiliates, sublicensees and other related parties, that the manufacture, use or sale of a product, the provision of any service, or the practice of any method that is, in each case, conducted with respect to a product or service that uses ECL technology and is conducted after completion of the merger infringes certain Roche and Roche Diagnostics ECL patents that are filed or acquired after the completion of the merger. Those ECL patents owned by Roche or Roche Diagnostics or their affiliates that claim their earliest priority from a patent application filed on or before the completion of the merger are licensed to BioVeris under the improvements license agreement. Also, each of BioVeris, MSD and MST agreed on behalf of themselves and their respective affiliates that, effective simultaneously with the completion of the merger, they would not, directly or indirectly, pursue any claim against Roche, Roche Diagnostics, the license sub or any of their respective affiliates and other related parties, that the manufacture, use or sale of a product or the provision of any service or the practice of any method that is, in each case, conducted with respect to a product or service that uses ECL technology in the field and is conducted after completion of the merger infringes certain BioVeris, MSD or MST ECL patents that are filed or acquired after the completion of the merger. Those ECL patents owned by IGEN or its affiliates, excluding MSD and MST, that claim their earliest priority from a patent application filed on or before the completion of the merger are licensed to the license sub under the license agreement. The covenants do not, however, prevent actions or claims based on violations of the license agreement or the improvements license agreement. 13 PCR LICENSE AGREEMENTS (PAGE 109) Under the PCR license agreements entered into simultaneously with the execution and delivery of the merger agreement, F. Hoffmann-La Roche Ltd, Roche Diagnostics and Roche Molecular Systems, Inc. granted to BioVeris and its affiliates, effective simultaneously with the completion of the merger and in return for a license fee of $50 million plus royalties as specified in the PCR license agreements, worldwide, non-exclusive licenses under patents that cover PCR inventions for: - the performance of sample collection, preparation, transport and/or isolation of nucleic acid sequences using PCR; - the amplification of nucleic acid sequences using PCR; - the detection of nucleic acid sequences using PCR; - the synthesis, purification, labeling and/or immobilization of nucleic acid probes used in PCR; and/or - the control of contamination. The licenses may be used to make, use and sell certain products and perform certain services in specified fields.

BioVeris is a newly formed, wholly-owned subsidiary of IGEN. Upon completion of the merger and related transactions, BioVeris will become an independent, publicly-traded company. The assets and businesses BioVeris will assume as part of the restructuring have historically been owned and operated by IGEN. The following risks relating to BioVeris and its businesses assumes the restructuring and the merger and related transactions have been completed. RISKS RELATING TO THE MERGER AND RELATED TRANSACTIONS DIRECTORS OF IGEN HAVE POTENTIAL CONFLICTS OF INTEREST IN RECOMMENDING THAT YOU VOTE IN FAVOR OF ADOPTION OF THE MERGER AGREEMENT. The members of the IGEN board of directors have personal interests in the merger and related transactions that are or may be different from, or in addition to, the interests of other IGEN stockholders. These interests include: - accelerated vesting of options to acquire 270,633 shares of IGEN common stock, in the aggregate, which would entitle IGEN's directors to receive, in the aggregate, approximately $4.9 million and 270,633 shares of BioVeris common stock; - continued rights to indemnification and exculpation from liabilities for certain acts or omissions; - continued coverage under directors' and officers' liability insurance with limits of $30 million for claims arising from or related to facts or events which occurred at or prior to the completion of the merger; - continued employment of IGEN's two directors who are also executive officers in similar positions with BioVeris for annual salaries anticipated to be initially comparable to the current salaries being received from IGEN, which is approximately $743,000 in the aggregate; - receipt by IGEN's two directors who are also executive officers in their capacities as executive officers of a transaction bonus simultaneous with completion of the merger and related transactions in the aggregate amount of approximately $1.7 million; and - appointment of the members of the IGEN board of directors (other than Mr. Richard Cass) to the BioVeris board of directors with each non-employee director entitled to receive a $10,000 annual retainer, a $1,000 attendance fee per meeting attended, the options discussed in the next paragraph and additional fees for serving on committees of the BioVeris board of directors, which represent an increase from the compensation non-employee directors were entitled to receive from IGEN. Furthermore, if approved by IGEN stockholders, BioVeris will adopt the BioVeris 2003 stock incentive plan pursuant to which each of BioVeris's non-employee directors will automatically receive annual grants of options to purchase 4,000 shares of BioVeris common stock and BioVeris's executive officers will be eligible to receive option grants and other equity-based awards. In addition, as part of the merger and related transactions: - BioVeris has agreed to make a final capital contribution of $37.5 million (of which any amount in excess of $30 million will be funded by Mr. Samuel Wohlstadter, IGEN's and BioVeris's chairman and chief executive officer, through the purchase of shares of BioVeris series B preferred stock that economically mirror the class C interests in MSD to be held by BioVeris) to MSD, a company formed by IGEN and MST, which is a company established and wholly-owned by Mr. Jacob Wohlstadter, a son of Mr. Samuel Wohlstadter; - BioVeris has agreed to assume IGEN's obligations under a letter agreement dated August 15, 2001, between the indemnified parties and IGEN. Pursuant to the letter agreement, IGEN agreed to fund 18 the reasonable ongoing legal fees and related charges and costs incurred by the indemnified parties arising out of or related to the Roche litigation, including any legal fees and related charges and costs arising out of or related to any of IGEN's ongoing negotiations regarding, and the settlement of, the Roche litigation. MSD has submitted to IGEN invoices for legal fees and expenses for the period from March 1, 2003 through September 30, 2003 in the amount of approximately $1.3 million that it asserts were reasonably incurred in connection with the indemnified parties' participation and involvement in IGEN's ongoing negotiations and settlement of the Roche litigation and their review of the documents relating to the merger and related transactions. The indemnified parties have claimed that IGEN must reimburse these fees and expenses pursuant to the letter agreement. The JVOC, through its counsel, has reviewed the relevant invoices, and has approved the payment to MSD of, and IGEN has paid, approximately $423,000 of the submitted invoices, which the JVOC believes is the amount IGEN is obligated to pay under the terms of the letter agreement for the period from March 1, 2003 through September 30, 2003. The indemnified parties, through their counsel, have not accepted the JVOC's determination, and the JVOC believes it is likely that the indemnified parties will continue to seek reimbursement for the balance of the $1.3 million claimed, which approximates $877,000. In addition, MSD submitted to IGEN invoices for legal fees and expenses of approximately $26,000 for October 2003 and approximately $21,000 for November 2003, which the indemnified parties have also claimed that IGEN must reimburse pursuant to the letter agreement. The JVOC has not yet made any determination regarding MSD's claims for October 2003 and November 2003. The JVOC expects that the indemnified parties will submit claims for reimbursement of additional expenses for the period from December 1, 2003 through the completion of the merger; - BioVeris has agreed to assume IGEN's obligations under Mr. Jacob Wohlstadter's employment agreement, consulting agreement and indemnification agreement, pursuant to which Mr. Jacob Wohlstadter will be entitled to receive an annual salary of $250,000 plus bonus and benefits from MSD, compensation from BioVeris for consulting services, if any, that may be provided to and at the request of BioVeris and indemnification by BioVeris against claims arising from services rendered to BioVeris; and - BioVeris has agreed to assume all of IGEN's current agreements and understandings with companies controlled by Mr. Samuel Wohlstadter, including certain shared services agreements and license agreements. For a more complete description, see "The Merger and Related Transactions -- Interests of IGEN's Directors and Executive Officers in the Merger and Related Transactions." The receipt of these benefits or the undertaking of certain obligations by BioVeris in connection with the merger and related transactions may have influenced these directors in making their recommendation that you vote in favor of the adoption of the merger agreement. DEPENDING ON BIOVERIS'S STOCK PRICE ON THE FIRST DAY OF TRADING AFTER THE COMPLETION OF THE MERGER, BIOVERIS COULD BE REQUIRED TO PAY UP TO $20 MILLION TO IGEN, WHICH WOULD CONSIDERABLY REDUCE BIOVERIS'S AVAILABLE CASH. Under the tax allocation agreement, BioVeris is required to make a payment to IGEN of up to $20 million. The amount of the payment will depend upon the average of the high and low trading prices of BioVeris common stock on the first day of trading after completion of the merger. The amount of the payment, which will not exceed $20 million, will equal 40% of the excess of: - the product of (1) the average of the high and low trading price for a share of BioVeris common stock on the first day of trading after the completion of the merger and (2) the number of shares of BioVeris common stock distributed in the merger; over - $100 million plus the amount of cash and cash equivalents as reflected on BioVeris's balance sheet, as measured immediately after the completion of the merger. 19 The distribution of BioVeris stock will be a taxable transaction for IGEN and the purpose of this payment is for BioVeris to share in a portion of the tax that IGEN might incur as a result of that distribution. The formula, which takes into account the expected approximate tax basis and tax rate that would be used in IGEN's calculation of its tax, was negotiated by Roche and IGEN as part of the overall negotiation of the merger. There is currently no public trading market for the shares of BioVeris common stock, and BioVeris is unable to predict the trading price for its common stock. A payment will be due if the average of the high and low market capitalization for BioVeris on the first day of trading of BioVeris common stock after completion of the merger is at least $305 million, or approximately $11.41 per share and the maximum payment will be due if the average exceeds $355 million, or approximately $13.28 per share, in each case based on the assumption that BioVeris will have $205 million in cash and cash equivalents immediately after the completion of the merger and prior to making any payments due pursuant to the related transaction agreements, the ongoing commercial agreements or the MSD letter agreement. Any payment by BioVeris to IGEN would reduce BioVeris's available cash and could have a material adverse effect on BioVeris's business. THE AMOUNT AND CHARACTER OF INCOME, GAIN OR LOSS YOU MAY RECOGNIZE AS A RESULT OF THE MERGER AND RELATED TRANSACTIONS CANNOT BE PRECISELY DETERMINED. The merger and related transactions are intended to constitute a single integrated transaction for U.S. Federal income tax purposes pursuant to which each holder of IGEN common stock generally will recognize capital gain or loss, if any, equal to the difference between (1) the sum of the amount of cash received in the merger plus the fair market value of BioVeris common stock received by such holder at the time of the distribution of BioVeris common stock in connection with the merger and (2) the holder's adjusted basis in the IGEN common stock immediately prior to the transaction. However, if the U.S. Internal Revenue Service were to successfully assert that the value of the BioVeris common stock received or the cash merger consideration received should be treated as a dividend, rather than as proceeds attributable to a sale or exchange of IGEN common stock, the relevant holder of IGEN common stock would have to include the full amount of such dividend in its income without being able to offset its basis in its IGEN common stock against such dividend. See "The Merger and Related Transactions -- U.S. Federal Income Tax Consequences." RISKS RELATING TO BIOVERIS AND ITS BUSINESS THE IGEN BUSINESSES THAT BIOVERIS WILL ASSUME HAVE A HISTORY OF LOSSES AND BIOVERIS WILL HAVE FUTURE LOSSES AND NEGATIVE CASH FLOW. BioVeris incurred net losses of $23.8 million for the six months ended September 30, 2003, and $50.9 million, $49.2 million and $30.7 million for the years ended March 31, 2003, 2002 and 2001, respectively. BioVeris expects to continue to incur operating losses and negative cash flow as a result of its expenses for manufacturing, marketing and sales capabilities, research and product development, general and administrative costs and its share of losses in MSD. BioVeris's net loss is expected to increase in the period in which the merger is completed as a result of BioVeris's recognition of an allocated one-time noncash compensation charge associated with the cancelation of IGEN stock options and the payment of the merger consideration for each share covered by IGEN stock options in connection with the merger. Upon completion of the merger, depending on the average first day trading price of BioVeris common stock, BioVeris will record a compensation charge for each IGEN stock option. BioVeris cannot predict what the average first day trading price of its common stock will be, however the table set forth below provides a range of hypothetical average first day trading prices for BioVeris common stock and the projected compensation charge if such price is the actual average first day trading price. The hypothetical average first day trading prices for BioVeris common stock have been provided for illustrative purposes only and are not intended to forecast or be indicative of the possible future performance of BioVeris common stock and BioVeris cannot provide any assurance that the average first day trading price of its common stock will be equal to any of the prices in the table set forth below. The table below includes 20 approximated compensation charge attributable to employee and nonemployee stock options based on these hypothetical first day trading prices for BioVeris common stock. APPROXIMATE HYPOTHETICAL AVERAGE FIRST DAY PROJECTED NONCASH TRADING PRICE OF COMPENSATION BIOVERIS COMMON STOCK CHARGE ------------------------------ ----------------- $0.00....................................................... $ 8,200,000 $5.00....................................................... 9,600,000 $10.00...................................................... 11,000,000 $11.75...................................................... 11,500,000 $12.00...................................................... 43,100,000 $15.00...................................................... 46,300,000 For a description of the calculation of the compensation charge, see "Management's Discussion and Analysis -- Results of Operations -- Six Months Ended September 30, 2003 and 2002." While BioVeris seeks to attain profitability, BioVeris cannot be sure that it will ever achieve product or other revenue sufficient for it to attain this objective. BioVeris's ability to become profitable in the future will depend on, among other things, BioVeris's ability to: - expand the distribution and increase sales of certain of its products; - upgrade and enhance the M-SERIES family of products; - introduce new products into the market; - develop its marketing, sales and distribution capabilities cost-effectively; and - continue certain former IGEN collaborations and establish successful new collaborations with corporate partners to develop and market products that incorporate its technologies and provide necessary funding. IF BIOVERIS IS UNABLE TO ESTABLISH NEW COLLABORATIONS, OR ANY COLLABORATIONS BIOVERIS ESTABLISHES DO NOT RESULT IN THE SUCCESSFUL INTRODUCTION OR MARKETING OF NEW PRODUCTS BASED ON BIOVERIS'S TECHNOLOGY, BIOVERIS'S GROWTH MAY BE SLOWED AND ITS BUSINESS COULD BE MATERIALLY ADVERSELY AFFECTED. One aspect of BioVeris's strategy is to enter into collaborative relationships with established healthcare and other companies to assist BioVeris in developing its technologies or manufacturing or marketing its products for certain markets. BioVeris may not be able to enter into collaborations on terms that are favorable to it, if at all. In addition, BioVeris cannot assure you that third parties, including its licensees (such as MSD, Roche or bioMerieux, Inc., which is referred to in this proxy statement/ prospectus as bioMerieux), suppliers or others will not object to possible new collaborations. See "Risk Factors -- Risks Relating to BioVeris and Its Business -- MSD and BioVeris may have different views of the scope of the exclusive license previously granted to MSD and the scope of MSD's rights under its joint venture agreement with BioVeris, which could affect BioVeris's ability to expand its business directly or through collaborations." As a result of this strategy, BioVeris may have no, or only limited, control over the amount of resources that its collaborators will devote to the development or marketing of products based on BioVeris's technology. For instance, BioVeris's collaborators: - may decide not to, or may fail to successfully, develop, market or sell products based on BioVeris's technology; - may not devote sufficient resources to the development, marketing or sale of these products based on BioVeris's technology; or - may terminate their agreements with BioVeris. 21 If any of these events occur with respect to one of the companies BioVeris is collaborating with, BioVeris would not receive the benefits of the collaboration and BioVeris's growth could be slowed and its business could be materially adversely affected. TO ACHIEVE COMMERCIAL SUCCESS, BIOVERIS MUST COMPLETE THE DEVELOPMENT OF ITS PRODUCTS AND THOSE PRODUCTS MUST GAIN MARKET ACCEPTANCE OR BIOVERIS'S BUSINESS COULD BE MATERIALLY ADVERSELY AFFECTED. Many of BioVeris's potential products, including certain M-SERIES products, are at an early stage of development and BioVeris has not introduced any clinical diagnostics products. Products under development require additional research and development efforts, including clinical testing and regulatory approval, prior to commercial use. BioVeris's potential products are subject to the risks of failure inherent in the development of products based on new technologies. These risks include the possibilities that: - BioVeris's design or approach may not be successful; - BioVeris's products may not be compatible with existing technology or may rely on technology that has become obsolete; - BioVeris's products may be found ineffective or fail to meet the applicable regulatory standards or receive necessary regulatory clearances; - BioVeris's estimates of the market size and potential for its products may prove incorrect; - third parties may market superior or equivalent products; - BioVeris's products may not be recognized in the market due to unfamiliar brand names; or - BioVeris's product development costs may outweigh potential future cash flows associated with those products. BioVeris's business, business prospects and financial results would be hurt if its products are not accepted as alternatives to other existing or new products and do not gain market acceptance. In addition, BioVeris has licensed, for a license fee of $50 million plus royalties as specified in the PCR license agreements, certain PCR technology from Roche, which PCR technology BioVeris plans to integrate into certain of its new instrument systems. Although BioVeris does not currently sell, or have under development, any product based on the PCR technology being licensed from Roche, any products that BioVeris may develop using PCR technology will be also subject to the risks of failure inherent in the development of products based on new technologies as described above. If BioVeris is unable to successfully develop any products using PCR technology because such PCR technology has become obsolete or the future undiscounted cash flows attributable to products using PCR technology are insufficient to realize the remaining carrying value of the license, BioVeris would be required to write-off the remaining net book value or record an impairment of the value of the PCR license. Furthermore, if as a result of the claims made by Applera Corporation and its affiliate Applied Biosystems, which are referred to in this proxy statement/prospectus as Applied Biosystems, against Roche, BioVeris is unable to use the PCR technology being licensed from Roche, BioVeris would also be required to write-off the remaining net-book value of the PCR license. Such a write-off or the recording of such an impairment could have a material adverse effect on BioVeris's future financial position or results of operations. BIOVERIS'S QUARTERLY OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY, AND THESE FLUCTUATIONS MAY CAUSE ITS STOCK PRICE TO BE VOLATILE. BioVeris's quarterly operating results will depend upon: - the volume and timing of orders and product deliveries for biodefense products, M-SERIES systems or other products, which orders and deliveries are based on BioVeris's customers' requirements; 22 - the success of M-SERIES system upgrades and enhancements, which upgrades and enhancements involve increased product costs at the time of the upgrade or enhancement, and customer acceptance of those enhancements and upgrades; - the amount of revenue recognized from royalties and other contract revenues, which revenues are dependent upon the efforts of BioVeris's licensees and collaborators; - whether BioVeris's instruments are sold or leased to customers, which will affect the timing of the recognition of revenue from the sale or lease; - the timing of BioVeris's introduction of new products, which could involve increased expenses associated with product development and marketing; - the volume and timing of product returns and warranty claims, which, if products are returned or have warranty claims that are unexpected, may involve increased costs in excess of amounts reserved for returns or claims; - BioVeris's competitors' introduction of new products, which may affect the purchase decision of or timing of orders by BioVeris's customers and prospective customers while the competitors' product is assessed; - the amount of expenses BioVeris incurs in connection with the operation of its business, including - research and development costs, which increases or decreases based on the products in development and - sales and marketing costs, which are based on product launches or promotions and sales incentives that might be in effect from time to time; - the amount that BioVeris will record each quarter related to the amortization or impairment of the license to use PCR technology, which may increase based on the outcome of the litigation and arbitration commenced against Roche by Applied Biosystems relating to Roche's and Applied Biosystems' respective rights to PCR technology; - unexpected termination of government contracts or orders, which could result in decreased sales and increased costs due to excess capacity, inventory, personnel and other expenses; and - BioVeris's share of losses in MSD, which are based on results of MSD's operations, which for the three and six months ended September 30, 2003 totaled $4.5 million and $9.7 million, respectively, compared to $5.0 million and $9.5 million for the three and six months ended September 30, 2002. These factors may cause BioVeris's quarterly operating results to fluctuate significantly, which in turn, may cause its stock price to be volatile. In addition, because BioVeris's revenues and operating results are expected to be volatile and difficult to predict, BioVeris believes that period-to-period comparisons of its results of operations will not be a good indication of its future performance. THE ACCOMPANYING BIOVERIS CONSOLIDATED FINANCIAL STATEMENTS MAY NOT NECESSARILY BE INDICATIVE OF BIOVERIS'S FINANCIAL POSITION, RESULTS OF OPERATIONS OR CASH FLOWS HAD BIOVERIS BEEN OPERATED ON A STAND-ALONE BASIS. The assets and businesses of BioVeris have historically been owned, operated and fully integrated with IGEN. The accompanying consolidated financial statements of BioVeris have been prepared and are presented as if BioVeris had been operating as a separate entity. In order to fairly present the operating results of BioVeris, these financial statements reflect the application of certain estimates and allocations. BioVeris's consolidated statements of operations include all revenues and costs that are directly attributable to the BioVeris businesses, as well as certain expenses of IGEN that have been allocated to BioVeris using various assumptions. These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs) which were allocated based upon percentage of total revenue or percentage of total 23 headcount, as appropriate. While management believes that the allocation methodologies are reasonable and appropriate, different allocation methodologies would result in changes to BioVeris's operating results. Upon completion of the merger and related transactions, BioVeris will become an independent, publicly-traded company and will therefore be operated on a stand-alone basis. The financial information in the accompanying BioVeris consolidated financial statements may not reflect the financial position, results of operations and cash flows of BioVeris in the future or what they would have been had BioVeris been operating as a stand-alone entity in the past. BIOVERIS MAY NOT BE ABLE TO RAISE SUFFICIENT ADDITIONAL CAPITAL TO SUCCESSFULLY DEVELOP ITS BUSINESS. BioVeris will need substantial amounts of money to fund its operations on an ongoing basis. Upon the completion of the merger and related transactions and following the final capital contribution to MSD, BioVeris expects to have approximately $125 million in cash available to operate and invest in its business, subject to a possible payment of up to $20 million to IGEN pursuant to the tax allocation agreement. BioVeris expects its available cash to be sufficient to fund its operations for at least one year, but cannot predict how long its available cash will be sufficient to fund its operations thereafter. BioVeris may need to raise substantial amounts of money to fund a variety of future activities integral to the development of its business, including: - for research and development to successfully develop BioVeris's technologies; - to obtain regulatory approval for BioVeris's products; - to file and prosecute patent applications to protect BioVeris's technology; - to respond to innovations that BioVeris's competitors develop; - to retain qualified employees, particularly in light of competition for qualified scientists and engineers; - to make new arrangements to market BioVeris's technology; - to manufacture products itself or through a third party; - to provide funding for expanded or new facilities; and - to market different products to different geographic markets, either through expanding its sales and distribution capabilities or relying on a third party. The failure to raise sufficient additional capital for BioVeris to develop its business would adversely affect its business prospects. BIOVERIS'S ACCESS TO FUNDS COULD BE NEGATIVELY IMPACTED BY MANY FACTORS, INCLUDING VOLATILITY IN THE PRICE OF BIOVERIS COMMON STOCK, LOSSES FROM OPERATIONS AND CAPITAL MARKET CONDITIONS. BioVeris may not have access to enough funds on favorable terms, if at all, to successfully operate and develop its business. BioVeris may try to raise necessary additional capital by issuing additional debt or equity securities. Holders of debt securities would have priority over BioVeris's equity holders with respect to the proceeds from the sale of its assets in the event of liquidation of its business, and any debt financings BioVeris obtains may contain restrictive terms that limit BioVeris's operating flexibility. If BioVeris raises additional capital by selling additional common or preferred stock, the holdings of existing stockholders would be diluted. If BioVeris is unable to raise additional capital it may have to consider pursuing arrangements with other companies that may not be available on terms favorable to BioVeris. In addition, BioVeris may have to scale back, or even eliminate, some of its programs. 24 BIOVERIS MAY EXPERIENCE DESIGN, DEVELOPMENT, IMPLEMENTATION AND OTHER DIFFICULTIES THAT COULD DELAY OR PREVENT ITS INTRODUCTION OF NEW OR ENHANCED PRODUCTS OR AFFECT THE PERFORMANCE OF EXISTING PRODUCTS, WHICH COULD ADVERSELY AFFECT ITS BUSINESS. IN ADDITION, IF THE MARKETS FOR BIOVERIS'S PRODUCTS CHANGE OR EVOLVE IN AN UNEXPECTED MANNER, BIOVERIS'S BUSINESS COULD BE MATERIALLY ADVERSELY AFFECTED. The development of new or enhanced products is a complex and uncertain process requiring the accurate anticipation of technological and market trends as well as precise technological execution. BioVeris may experience design, development, implementation and other difficulties that could delay or prevent its introduction of new or enhanced products, or products that BioVeris may develop, manufacture or market with third parties or affect the performance of existing products, such as those which IGEN experienced with the development of M-SERIES instruments. These difficulties and delays may cause expenses to increase and BioVeris's product sales to fluctuate. In addition, if BioVeris experiences design, development or implementation difficulties in developing, manufacturing, distributing or marketing these instruments, it would sell fewer of its products and its business prospects would be adversely affected. BioVeris expects the markets for its products to change and evolve. These changes could facilitate the market demand for BioVeris's new or enhanced products, including the need for products that could be utilized in clinical point-of-care sites and field-testing of environmental samples in the biodefense market. If market demand does not change or evolve as BioVeris anticipates or if BioVeris is not able to develop products that meet the evolving market demand, its business prospects would be adversely affected. In addition, the markets for BioVeris's products are characterized by evolving industry standards and government regulations, the need for updated and effective technology and new product introductions. BioVeris's success will depend in part upon its ability to profitably enhance existing products and develop and introduce new products. BioVeris may not be able to avoid the obsolescence of its products due to technological change and evolving industry standards and government regulations. If BioVeris experiences design, development, implementation or other difficulties that delay or prevent its introduction of new or enhanced products or if the markets change or evolve in an unexpected manner, BioVeris's business could be materially adversely affected. BIOVERIS EXPECTS TO RELY ON SALES OF THE M-SERIES PRODUCT FAMILY FOR A SIGNIFICANT PORTION OF ITS REVENUES, AND A DECLINE IN SALES OF THESE PRODUCTS COULD CAUSE ADVERSE FINANCIAL RESULTS AND NEGATIVELY AFFECT BIOVERIS'S BUSINESS PROSPECTS. BioVeris expects to derive a significant portion of its revenues from sales of M-SERIES products. Any factor adversely affecting the pricing or demand of M-SERIES products, including market acceptance of competing products, could cause BioVeris's revenues to decline, resulting in adverse financial results and negatively affecting BioVeris's business prospects. Additionally, BioVeris intends to market M-SERIES products in markets in which BioVeris has little or no experience. BioVeris may not be able to successfully market the M-SERIES family of products in those markets, which could cause an adverse affect on BioVeris's business prospects. BIOVERIS'S COMPETITORS AND POTENTIAL COMPETITORS MAY HAVE OR DEVELOP DIAGNOSTIC PRODUCTS AND TECHNOLOGIES THAT ARE MORE ATTRACTIVE THAN BIOVERIS'S EXISTING OR FUTURE DIAGNOSTIC PRODUCTS. BioVeris's business will be subject to intensive competition from established companies, development stage companies and research and academic institutions, and BioVeris expects this competition to intensify. Many of these companies and institutions have one or more competitive advantages over BioVeris, including, among other things: - more money to invest; - more established diagnostic products; - long-standing relationships with customers; 25 - greater expertise and resources in developing, manufacturing, marketing and selling diagnostic products; - a larger, more experienced workforce; and - more experience in obtaining regulatory approval for clinical testing products. As a result, BioVeris's competitors may develop, manufacture market or sell diagnostic products that are more effective or commercially attractive than BioVeris's current or future diagnostic products. In addition, these competitors may offer broader product lines, discounts and may have greater name recognition than BioVeris. Furthermore, BioVeris competes against companies that utilize ECL technology licensed to them by BioVeris, including Roche and MSD, a company in which BioVeris also has an interest. As a result, BioVeris may not be able to compete successfully against its competitors. This could have a material adverse effect on BioVeris's business, financial condition and revenues. BIOVERIS HAS LIMITED MANUFACTURING EXPERIENCE, WHICH PUTS IT AT A COMPETITIVE DISADVANTAGE AND COULD HAVE A MATERIAL ADVERSE EFFECT ON BIOVERIS'S BUSINESS, FINANCIAL CONDITION AND REVENUE. BioVeris lacks experience in large-scale manufacturing and has no experience in the manufacturing of clinical diagnostic products, which could hamper its ability to manufacture existing products or new products that it develops. BioVeris has two options to address this competitive disadvantage. First, BioVeris could expand its internal ability to manufacture products, which, to date, has only been done in a limited way. Second, BioVeris could contract with a third party to manufacture products for it based on its technology, which, to date, it has not done. If BioVeris is unable to expand its own manufacturing capability or find a suitable manufacturer on acceptable terms in a timely manner, BioVeris may be unable to meet demand for existing products and could be delayed in introducing new products to the market. Failure to meet demand for existing products or delays in introducing new products could put BioVeris at a competitive disadvantage and could have a material adverse effect on BioVeris's business, financial condition and revenue. BIOVERIS HAS LIMITED MANUFACTURING FACILITIES FOR ITS PRODUCTS AND BIOVERIS MAY NOT FIND ADDITIONAL FACILITIES SUITABLE FOR FUTURE GROWTH, WHICH COULD MATERIALLY ADVERSELY AFFECT ITS BUSINESS AND PROSPECTS. BioVeris faces risks inherent in operating a single facility for the manufacture of its products. BioVeris does not have alternative production facilities available should its Gaithersburg, Maryland manufacturing facility cease to function. If BioVeris's facility were not operational for an extended period of time, including due to an unforeseen plant shutdown, then BioVeris's business and future prospects could be materially adversely affected. In addition, BioVeris may need to expand and enhance its research, development and production facilities. BioVeris may encounter difficulties in locating suitable additional facilities to meet its requirements. BioVeris may also be required to make material capital expenditures at a new facility at a time when it has limited capital resources available to it. BioVeris may also experience difficulties or delays in integrating its operations into new facilities. These difficulties might include delays in the availability of a new facility or problems associated with equipment installation. In addition, any facility that BioVeris obtains for production of clinical testing or biodefense products will be subject, on an ongoing basis, to a variety of regulatory requirements including quality systems regulations, international quality standards and other regulatory standards. BioVeris may encounter difficulties expanding its manufacturing operations in accordance with these regulations and standards, which could result in manufacturing delays and an inability to meet product demand and its business prospects could be materially adversely affected. If BioVeris is not successful at identifying and obtaining additional facilities to meet its future growth needs, or BioVeris is unable to pay for facility enhancements and improvements, its business would suffer. 26 BIOVERIS HAS NO EXPERIENCE SELLING, MARKETING OR DISTRIBUTING CLINICAL DIAGNOSTIC PRODUCTS. ITS FAILURE TO ESTABLISH A SALES FORCE WITH TECHNICAL EXPERTISE OR TO ESTABLISH AN EFFECTIVE DISTRIBUTION SYSTEM FOR ITS CLINICAL DIAGNOSTIC PRODUCTS COULD MATERIALLY ADVERSELY AFFECT BIOVERIS'S BUSINESS PROSPECTS AND REVENUES. BioVeris needs to develop selling, marketing and distribution capabilities for its planned clinical diagnostic products. To market clinical diagnostic products directly to customers, and not through a licensee or third party distributor or collaborator, BioVeris will need to develop a substantial sales force with technical expertise. BioVeris will also need to establish a distribution system to support its sales force. Alternatively, BioVeris could license or contract with another company to provide sales and distribution services for its products. BioVeris may not be able to develop a sufficient sales and distribution force or find a suitable company to fill that role for it, which could materially adversely affect BioVeris's business prospects and revenues. FAILURE TO MANAGE BIOVERIS'S GROWTH COULD ADVERSELY AFFECT BIOVERIS'S BUSINESS. BioVeris expects to grow by increasing its presence in existing markets and introducing new products it develops into new potential markets. BioVeris's growth strategy will place a strain on its management and its operating and financial systems. As BioVeris grows, its personnel, systems, manufacturing capabilities and resources, procedures and controls may be inadequate to support future operations and BioVeris will need to hire, train and retain additional personnel. BioVeris may also need to improve and expand its financial and management controls, reporting systems and operating systems as well as other aspects of its infrastructure, including research and development or manufacturing facilities. BioVeris may encounter difficulties integrating additional personnel, as well as improving, expanding and integrating new systems or facilities, which could adversely affect BioVeris's business. THE SUCCESS OF BIOVERIS'S BUSINESS DEPENDS ON PATENTS THAT WILL EXPIRE OVER TIME AND THAT MUST BE ACTIVELY PURSUED, OBTAINED, MAINTAINED AND PROTECTED. BIOVERIS'S BUSINESS COULD BE HARMED IF IT HAS FUTURE DISAGREEMENTS WITH ROCHE OVER THE SCOPE OF THE LICENSE AGREEMENT. BioVeris's business success or failure will depend, in part, on its ability to pursue, obtain, and maintain adequate patent protection for ECL technology and BioVeris's other technologies. BioVeris's patents may not adequately protect its technology from being used by its competitors. BioVeris's business depends heavily on patents that will expire over time and may be challenged or circumvented by competitors. Patents allow BioVeris, for a time, to prevent others it has not licensed from using BioVeris's inventions to compete against it. Companies may challenge or seek to invalidate patents or circumvent valid claims in patents, all of which could make it necessary for BioVeris to defend its patents in litigation. Litigation over patents poses the following risks to BioVeris's business: - litigation costs can be extremely high, which could drain BioVeris's financial resources; and - litigation over BioVeris's patents could discourage other companies from working with it to develop and market new products based on the technology covered by those disputed patents. If BioVeris loses some patent protection, its competitive advantage could be eroded, third parties may be able to use its technology without paying BioVeris and BioVeris's financial condition and business prospects would be adversely affected. Effective simultaneously with the completion of the merger, Roche, through the license sub, will be licensed by BioVeris to exploit ECL technology subject to the limitations described in the license agreement. Although IGEN and Roche negotiated the terms of the license agreement in an effort to minimize the areas of potential future disputes, there are no assurances that BioVeris and Roche will continue to agree on the scope, permitted use and other material terms of the license agreement. Future disputes with Roche over the scope of the license agreement, such as disputes over the field or the types of 27 products that Roche is permitted to develop and sell, might lead to lengthy and costly legal proceedings, which could adversely affect BioVeris's financial condition and future business prospects. BIOVERIS'S BUSINESS COULD BE HARMED IF IT INFRINGES, OR IS ALLEGED TO HAVE INFRINGED, THE INTELLECTUAL PROPERTY OF OTHERS. If BioVeris's products or services were to infringe the intellectual property (including patent rights) of others, BioVeris or its licensees could: - be required to alter, or abandon products or processes; - be required to obtain a license from the intellectual property holder; - lose customers that are reluctant to continue using BioVeris's or its licensees' products or services; - be forced to abandon development work with respect to these products; and - be required to pay damages that could be substantial. If BioVeris or its licensees infringe the intellectual property (including patent rights) of others, BioVeris's business could be damaged if BioVeris were unable to make necessary alterations or obtain a necessary license on acceptable terms, if at all. In addition, if BioVeris's products or services were alleged to have infringed the intellectual property (including patent rights) of others, BioVeris would be forced to defend itself in litigation and might be enjoined from further sale of its products or required to pay monetary damages or amounts in settlement of the suit, which could adversely affect BioVeris's prospects, drain its financial resources and discourage other companies from working with it. BECAUSE BIOVERIS INTENDS TO DEVELOP PRODUCTS THAT ARE BASED ON PATENTS AND TECHNOLOGY THAT IT HAS LICENSED FROM OTHERS, THE OWNERS OF THOSE PATENTS AND TECHNOLOGY MIGHT CLAIM THAT PRODUCTS DEVELOPED OR SOLD BY BIOVERIS VIOLATE THOSE LICENSES. ADDITIONALLY, A THIRD PARTY MIGHT OBJECT TO A LICENSE THAT BIOVERIS HOLDS OR TO THE SCOPE OF THE LICENSE GRANTED TO BIOVERIS. BioVeris's success or failure will also depend, in part, on the patent rights and technology of others, including patents and technology being licensed to BioVeris from affiliates of Roche. Effective simultaneously with the completion of the merger, BioVeris will be licensed by affiliates of Roche to exploit certain improvements from Roche Diagnostics and certain PCR technology, subject to the limitations described in the improvements license agreement and the PCR license agreements. Although IGEN and Roche negotiated the terms of the improvements license agreement and the PCR license agreements in an effort to minimize the areas of potential future disputes, there are no assurances that BioVeris and Roche will continue to agree on the scope, permitted use and other material terms of the improvements license agreement or the PCR license agreements. Future disputes with Roche over the scope, permitted use and other material terms of the improvements license agreement or the PCR license agreements, such as disputes over the field or types of products that BioVeris is permitted to develop and sell, may lead to lengthy and costly legal proceedings, or could interfere with or preclude BioVeris from proceeding with one or more development programs, whether conducted independently or through a collaborative arrangement. In addition, third parties may object to the scope, permitted use and other material terms of one or more of the licenses granted to BioVeris by certain Roche affiliates. For example, Roche has advised BioVeris that Applied Biosystems has notified Roche that one or more of the PCR licenses granted by certain Roche affiliates to BioVeris under the improvements license agreement and the PCR license agreements may infringe exclusive rights to PCR technology held by, or other contract rights of, Applied Biosystems. Applied Biosystems has commenced litigation and arbitration against Roche regarding their respective rights relating to PCR technology. Certain Roche affiliates have made certain representations and provided certain warranties on their right to grant the licenses that have been granted 28 to BioVeris, including representations and warranties that: the rights and licenses granted under the improvements license agreement and the performance by Roche Diagnostics of its obligations under the improvements license agreement will not conflict with any agreement, contract or other arrangement to which it is a party or by which it is bound; Roche Diagnostics has title to or license rights sufficient to grant such license rights granted under the improvements license agreement to BioVeris and its affiliates; Roche Diagnostics has not licensed or otherwise disposed of such licensed intellectual property rights in any manner that limits BioVeris's or its affiliates' exploitation of the licenses granted by Roche Diagnostics under the improvements license agreement; certain Roche affiliates have the full power and right to grant to BioVeris and its affiliates the licenses granted under the PCR license agreements; and the execution by certain Roche affiliates of the PCR license agreements will not constitute a breach or default under any contract, instrument or agreement to which such Roche affiliate or any of their affiliates are a party or by which such Roche affiliate or any of their affiliates are bound. Roche has advised IGEN that it believes Applied Biosystems' allegations are without merit and intends to contest them vigorously. There are no assurances that BioVeris will not be named as a defendant in either of those actions or that Roche will prevail in the litigation and arbitration, or that the terms of any resolution or settlement of these proceedings will not be unfavorable to BioVeris. If BioVeris is named as a defendant in either of those proceedings, it would be subject to the risks identified in the immediately preceding risk factor. Further, a final determination, settlement or other resolution in the arbitration or litigation may limit, preclude or interfere with Bioveris's ability to exploit certain PCR technology licensed under the improvements license agreement or the PCR license agreements. Although BioVeris does not sell, or have under development, any product based on the PCR technology being licensed from Roche, if Applied Biosystems prevails in its claims against Roche, BioVeris may be required to obtain a license from Applied Biosystems for certain patents covering PCR technology to avoid future potential claims of infringement related to any development program that it might establish for future products based on PCR technology and may face many of the risks described in the immediately preceding risk factor. Further, BioVeris licenses technology from other companies and academic institutions. Because access to this technology is necessary to operate its business, BioVeris must be certain that it complies with these license agreements. BioVeris's business could be harmed if it breached any of these license agreements and lost the rights to use this patented technology or if BioVeris were unable to renew existing licenses on acceptable terms, if at all, or get additional licenses that it may need on acceptable terms, if at all. In addition, BioVeris may need to litigate the scope and validity of patents held by others and such litigation could be a substantial cost for it. MSD AND BIOVERIS MAY HAVE DIFFERENT VIEWS OF THE SCOPE OF THE EXCLUSIVE LICENSE TO BIOVERIS'S TECHNOLOGY PREVIOUSLY GRANTED TO MSD AND THE SCOPE OF MSD'S RIGHTS UNDER ITS JOINT VENTURE AGREEMENT WITH BIOVERIS, WHICH COULD AFFECT BIOVERIS'S ABILITY TO EXPAND ITS BUSINESS DIRECTLY OR THROUGH COLLABORATIONS. BioVeris intends to expand its business through internal development programs and through new or expanded collaborative arrangements. MSD may view the scope of its exclusive license and other rights under its license agreement and other agreements with BioVeris in a way that interferes with or precludes BioVeris from proceeding with one or more development programs. BioVeris cannot assure you that MSD will not object to BioVeris's future business plans, whether conducted independently or through a collaborative arrangement. Additionally, MSD may believe that BioVeris must obtain MSD's consent prior to entering into proposed collaborative arrangements. The other party to a proposed collaboration with BioVeris may also require BioVeris to obtain MSD's consent to avoid any future disputes or disagreements. For example, in connection with the merger and related transactions, Roche required IGEN to obtain MSD's consent to the execution and delivery of the license agreement. In addition, MSD's consent is required for BioVeris to transfer its interests in MSD. If BioVeris is required to obtain MSD's consent for any reason, there are no assurances that BioVeris will be able to obtain that consent at all or on terms that would not have an adverse effect on BioVeris's business, financial condition or results of operations. In addition, if BioVeris chooses not to obtain MSD's consent, MSD may sue BioVeris to enforce rights it believes it has. Such a lawsuit could materially harm BioVeris's business and future business prospects. 29 BIOVERIS RELIES ON TRADE SECRETS AND OTHER INFORMATION THAT CANNOT BE PROTECTED BY PATENTS, WHICH COULD HARM BIOVERIS'S BUSINESS IF THEY WERE DISCLOSED TO OR INDEPENDENTLY DEVELOPED BY OTHERS. In addition to patents, BioVeris also relies in its business on trade secrets, know-how and other proprietary information. If this information were disclosed to or independently developed by competitors, BioVeris's business would suffer. BioVeris seeks to protect this information, in part, by entering into confidentiality agreements with licensees, employees and consultants that prohibit these parties from disclosing its confidential information. These agreements may not provide adequate protection for BioVeris's trade secrets, know-how and other proprietary information or ensure that the information BioVeris shares with others during the course of its business will remain confidential. BioVeris may not have sufficient legal remedies under the agreements or otherwise to correct or compensate for unauthorized disclosures or sufficient resources to seek redress. If BioVeris is not able to be adequately redressed for the unauthorized disclosure of its trade secrets, know-how or other proprietary information, its competitive position may be undermined and its business may suffer. BECAUSE BIOVERIS CANNOT USE THE IGEN NAME OR DERIVATIVES OF THE IGEN NAME OR NAMES THAT ARE CONFUSINGLY SIMILAR TO THE IGEN NAME AFTER THE COMPLETION OF THE MERGER, ITS EXISTING AND POTENTIAL CUSTOMERS, VENDORS, RECRUITING CANDIDATES AND INVESTORS MAY NOT RECOGNIZE THE NEW COMPANY NAME OR BRANDS, WHICH MAY CAUSE ITS REVENUES TO DECLINE AND ITS BUSINESS PROSPECTS TO SUFFER. BioVeris will assume IGEN's biodefense, life science and industrial product lines, which were previously marketed under the IGEN name or derivatives of the IGEN name. BioVeris's existing and potential customers, vendors and investors generally may not recognize the new brand. The name change may also cause difficulties in recruiting qualified personnel. If BioVeris fails to build strong brand recognition for its new brands, its revenues may decline and its business prospects may suffer. BIOVERIS DEPENDS ON A LIMITED NUMBER OF SUPPLIERS FOR MATERIALS USED IN THE MANUFACTURING OF ITS PRODUCTS, AND ANY INTERRUPTION IN THE SUPPLY OF THOSE MATERIALS COULD HAMPER ITS ABILITY TO MANUFACTURE PRODUCTS AND MEET CUSTOMER ORDERS. BioVeris depends on vendors to supply key materials that it uses in its products. Some of these materials are available only from limited sources. From time to time, suppliers may extend lead time, limit supplies or increase prices due to capacity constraints or other factors. In the event of a reduction in, interruption of, or degradation in the quality of the supply of any of the materials required by BioVeris, or an increase in the cost of obtaining those materials, BioVeris would be forced to locate an alternative source of supply. If no alternative source were available or if an alternative source were not available on a timely basis, at a reasonable cost or otherwise on acceptable terms, BioVeris's ability to manufacture one or more of its products would be delayed or halted. Any changes in sources of supply may require additional engineering or technical development to ensure consistent and acceptable performance of BioVeris's products. If any of these events occur, BioVeris's product costs may increase, it might be unable to deliver products in a timely fashion, it could lose sales as well as customers, and its business would be significantly harmed as a result. BIOVERIS DEPENDS ON HIGHLY TRAINED AND SKILLED EMPLOYEES AND MANAGEMENT, AND IT MAY NOT BE ABLE TO ATTRACT AND RETAIN SUFFICIENT PERSONNEL, WHICH COULD ADVERSELY AFFECT ITS BUSINESS. BioVeris needs to hire staff and retain its staff, both of which are difficult in a competitive marketplace. Because BioVeris is a technology company, it depends heavily on scientists and engineers to develop products and to build a successful business. Research and development efforts could suffer if BioVeris is not able to hire and retain enough qualified scientists and engineers, which would adversely affect its business. BioVeris competes with other technology companies and research and academic institutions for experienced scientists. Many of these companies and institutions have greater resources than BioVeris does and thus may be in a better position to attract desirable candidates. 30 In addition to scientists, BioVeris also needs to hire managers who have regulatory, manufacturing and marketing capabilities. If BioVeris is not able to hire managers with these skills, or develop expertise in these areas, its business could suffer. THE TRANSFER OF 54 IGEN EMPLOYEES TO MSD COULD ADVERSELY AFFECT BIOVERIS'S BUSINESS PROSPECTS AND FUTURE RESULTS OF OPERATIONS IF BIOVERIS IS NOT ABLE TO HIRE, TRAIN OR RETAIN NEW PERSONNEL TO PROVIDE THE SERVICES THAT MAY BE REQUIRED, OR RETAIN THESE SERVICES FROM MSD OR CONSULTANTS. In connection with the restructuring, during December 2003, 54 IGEN employees were offered and accepted employment at MSD. This includes 47 employees engaged in research, product development, manufacturing and operations support and approximately seven in general administration. The employees who were offered and accepted employment with MSD were primarily those that allocated more than a majority of their time during the past year to MSD projects and matters and the cost for whom were included in the value of BioVeris's in-kind contributions to MSD. The employees that have accepted employment with MSD include a significant percentage of BioVeris's software development, information technologies and intellectual property departments, including the heads of each of these departments. Accordingly, BioVeris's business prospects and future results of operations could be adversely affected if it is not able to either - obtain the services of these employees from MSD under acceptable terms or conditions, - hire, train and retain new qualified personnel in each of these departments to replace the former IGEN employees, or - retain the services of qualified and experienced consultants to provide the services that might be required. BioVeris does not have any agreement with MSD to obtain the services of any of the former IGEN employees that MSD has hired, and there cannot be any assurance that BioVeris will be able to reach agreement with MSD on acceptable terms and conditions, if at all. In addition, if BioVeris decides to hire, train and retain new qualified personnel or to retain the services of qualified and experienced consultants, the process of doing so may be lengthy and it may incur costs and expenses that might have an adverse effect on its future results of operations. BIOVERIS MAY CHANGE THE FOCUS OF ITS BUSINESS OR ENTER INTO NEW HEALTHCARE FIELDS, WHICH COULD RESULT IN THE INCURRENCE OF ADDITIONAL COSTS AND EXPOSURE TO ADDITIONAL OR DIFFERENT BUSINESS RISKS. BioVeris has broad discretion in determining the future strategy and focus of its business and may enter new healthcare fields in which it has limited or no experience. A significant change in the focus of BioVeris's business could result in a loss of its previous investment, the incurrence of additional costs, including research and development costs, and exposure to additional or different business risks. Incurrence of additional costs and exposure to additional risks could materially adversely affect BioVeris's business. BIOVERIS HAS A SUBSTANTIAL INVESTMENT IN MSD THAT, IF MSD IS NOT ABLE TO ADEQUATELY FUND ITS BUSINESS PLAN, COULD BECOME WORTHLESS. Following the completion of the merger, BioVeris will make a final capital contribution of $37.5 million (of which any amount in excess of $30 million will be funded by Mr. Samuel Wohlstadter through the purchase of shares of BioVeris series B preferred stock that economically mirror the class C interests in MSD to be held by BioVeris) to MSD, a company formed by IGEN and MST, which is a company established and wholly-owned by Mr. Jacob Wohlstadter, a son of Mr. Samuel Wohlstadter. As of September 30, 2003, $75.3 million had been invested in MSD, and the book value of BioVeris's interest in MSD as recorded on its balance sheet was approximately $14.8 million. BioVeris has no intention to provide additional funding to MSD after the final capital contribution is made. BioVeris expects that MSD will require substantial additional funding for its ongoing operations. If MSD is not able to obtain this funding, BioVeris could lose its ability to realize the value of most or all of its investment in MSD. 31 UPON THE COMPLETION OF THE MERGER, MSD AND MST HAVE THE RIGHT TO PURCHASE BIOVERIS'S INTEREST IN MSD AT A DISCOUNT FROM FAIR MARKET VALUE, PAYABLE OVER TIME IN INSTALLMENTS EQUAL TO THE SUM OF 5% OF THE MSD NET SALES, AS DETERMINED IN ACCORDANCE WITH THE MSD AGREEMENTS, AND 20% OF THE NET PROCEEDS REALIZED FROM CERTAIN THIRD-PARTY FINANCINGS IN ACCORDANCE WITH THE MSD AGREEMENTS, AND THERE IS NO ASSURANCE THAT THE PURCHASE PRICE WOULD EQUAL OR EXCEED THE BOOK VALUE OF BIOVERIS'S INTEREST IN MSD OR THAT SUCH FUTURE NET SALES OF MSD OR THIRD-PARTY FINANCINGS WILL MATERIALIZE. As part of the restructuring, IGEN's equity interest in MSD will be transferred to BioVeris because Roche did not want to acquire the interest. MSD and MST do not have the right to purchase IGEN's or BioVeris's, as the case may be, interest in MSD until the MSD joint venture agreement expires, or in certain cases, is terminated. The MSD joint venture agreement will expire upon completion of the merger and, as a result, MSD and MST will have the right to purchase for a purchase price equal to fair market value (to be determined in accordance with the provisions and procedures set forth in the MSD agreements, which will include a determination by appraisers if the parties are unable to agree on fair market value), less a 7.5% discount factor, BioVeris's entire interest in MSD, including BioVeris's preferred interests that entitle it to a preferred return on its investment in MSD. The MSD joint venture agreement also could be terminated prior to its expiration by MSD or MST as a result of a breach of IGEN's obligations, including IGEN's funding obligations to MSD, or as a result of MSD's termination of Mr. Jacob Wohlstadter's employment (other than for cause or disability), but BioVeris has no reason to believe such a breach will occur. MSD or MST has until 90 days following the expiration or termination of the joint venture agreement to exercise its right to begin the sale process. Under the MSD joint venture agreement, the parties must negotiate in good faith for 30 days to attempt to agree on a purchase price for BioVeris's interest. If the parties are unable to agree on the purchase price, the MSD joint venture agreement provides for an appraisal of the fair market value of BioVeris's interest in MSD. MSD or MST must exercise its right to purchase BioVeris's interest within 60 days after the purchase price has been determined. At September 30, 2003, the book value of BioVeris's interest in MSD as recorded on its balance sheet was approximately $14.8 million and, on a pro forma basis to recognize the final capital contribution to be made to MSD by BioVeris following the completion of the merger, would be approximately $52.3 million. In addition, after BioVeris makes its final capital contribution to MSD, it is expected to have preferred interests in MSD of approximately $107.6 million, exclusive of the up to $7.5 million of preferred interests to be funded by Mr. Samuel Wohlstadter through the purchase of BioVeris series B preferred stock to the extent the final capital contribution exceeds $30 million. BioVeris will no longer be entitled to a preferred return in the event MSD or MST elects to purchase BioVeris's interest in MSD and will only be entitled to receive the purchase price payable over time in installments equal to the sum of 5% of the MSD net sales, as determined in accordance with the MSD agreements, and 20% of the net proceeds realized or from certain third-party financings in accordance with the MSD agreements. In the event such future net sales of MSD or third-party financings do not materialize, BioVeris will not receive any payments from MSD or MST, as the case may be, for the purchase of BioVeris's interest in MSD. The parties must either agree on a fair value or the valuation of MSD is to be resolved through a third-party appraisal procedure described in the MSD agreements. If MSD or MST exercises its right to purchase BioVeris's interest in MSD, there can be no assurance that the purchase price for the MSD interests will be equal to or exceed the book value reflected on the BioVeris balance sheet. In the event the purchase price is less than the book value, BioVeris will not realize the carrying value of most or all of its investment in MSD. Furthermore, BioVeris will only be entitled to receive the purchase price payable over time in installments equal to the sum of 5% of MSD net sales, as determined in accordance with the MSD agreements, and 20% of the net proceeds realized from certain third-party financings in accordance with the MSD agreements. In the event such future net sales of MSD or third-party financings do not materialize, BioVeris will not receive any payments from MSD or MST, as the case may be, for the purchase of BioVeris's interest in MSD. The JVOC will, on behalf of BioVeris, conduct the negotiations to determine the purchase price of BioVeris's interest in MSD. Neither Mr. Samuel Wohlstadter, Dr. Richard Massey nor any other 32 interested party will participate on behalf of BioVeris in the negotiations. In addition, Dr. Richard Massey, who is IGEN's representative and who will be BioVeris's representative on the MSD board of managers and is and will be MSD's treasurer and secretary immediately following the restructuring, will not participate on behalf of MSD in the negotiations. For a further description of MSD's and MST's right to purchase BioVeris's interest in MSD, see "Certain Relationships and Related Party Transactions -- MSD and the MSD Agreements." BIOVERIS'S ABILITY TO DEVELOP PRODUCTS MAY BE NEGATIVELY AFFECTED BY SOCIAL ISSUES RELATING TO ANIMAL TESTING. BioVeris's research and development activities have occasionally involved, and in the future might involve, limited testing in mice and rats. In addition, testing in the future may involve other animals. Animal rights groups and other organizations and individuals have attempted to stop animal testing activities by pressing for legislation and regulation of such activities and by other means, BioVeris's ability to develop products may be negatively affected by a ban on animal testing or by action taken by groups or individuals opposed to these tests. RISKS RELATING TO REGULATION AND GOVERNMENT CONTRACTS BIOVERIS'S ABILITY TO OBTAIN AND RETAIN U.S. GOVERNMENT CONTRACTS IS SUBJECT TO UNCERTAINTIES, AND U.S. GOVERNMENT CONTRACTS MAY BE TERMINATED, WHICH COULD MATERIALLY ADVERSELY AFFECT BIOVERIS'S FINANCIAL CONDITION, OPERATING RESULTS, BUSINESS AND PROSPECTS. The U.S. government may refuse to permit BioVeris to assume U.S. government contracts from IGEN, and BioVeris's ability to secure additional contracts, is subject to uncertainties related to the government's future funding commitments. While BioVeris is not aware of any reason why the U.S. government would object to BioVeris's assumption of IGEN's U.S. government contracts, if the U.S. government were to refuse to permit BioVeris to assume these contracts, BioVeris's operating results and business prospects would be materially adversely affected. IGEN has requested that the U.S. government consent to the assignment to BioVeris of 26 active government contracts, consisting of 12 purchase orders or other agreements relating to the purchase of products, seven confidentiality agreements, three cooperative research and development agreements, two license agreements, one research grant and one product evaluation agreement. Substantially all of the revenue to be derived from these contracts is attributable to two contracts with the Department of Defense, or the DOD, one of which is for the purchase of up to $23.0 million of ECL technology-based tests for the detection of specific toxins in environmental samples and the second of which is for approximately $591,000 for the development of tests for the detection of select agents in food. The tests being sold by BioVeris are based on ECL technology and do not depend on any technology licensed from Roche. In addition, IGEN is seeking the consent of the U.S. government for the transfer to BioVeris of 22 completed contracts that have expired or for which all obligations have been satisfied. IGEN is seeking this consent because under the restructuring agreement, these contracts and the associated liabilities are required to be transferred to BioVeris. For a further description of the assets and liabilities that will be transferred to BioVeris and those that will remain with IGEN following the restructuring, see "Restructuring Agreement -- Transfer of Assets" and "Restructuring Agreement -- Assumption of Liabilities." BioVeris does not expect that any material liabilities will arise from the transfer of the 22 completed contracts from IGEN to BioVeris. The DOD's legal counsel has reviewed and found acceptable from a legal perspective the form of novation agreement that BioVeris has prepared for transferring the DOD and other U.S. government contracts from IGEN to BioVeris. However, under applicable legal requirements the DOD consent to the transfer of the DOD contracts and other U.S. government contracts cannot be obtained until the restructuring is completed. The prospects for BioVeris's biodefense business are also highly sensitive to changes in national and international government policies and funding priorities. Changes in domestic or foreign government policies or priorities, including funding levels through agency or program budget reductions by the 33 U.S. Congress or executive agencies, could materially adversely affect BioVeris's ability to retain or obtain U.S. government contracts, and its business prospects could suffer. The U.S. government can terminate, suspend or modify any of its contracts with BioVeris either for its convenience or if BioVeris defaults by failing to perform under the terms of the applicable contract. A termination or suspension for convenience could result in BioVeris having excess capacity, inventory, personnel, unreimbursable expenses or charges or other adverse effects on its financial condition. A termination arising out of BioVeris's default could expose BioVeris to claims for damages and may have a material adverse effect on its ability to compete for future U.S. government contracts and orders. U.S. government contracts may span one or more years and may include multiple renewal options in favor of the U.S. government. U.S. government agencies generally have the right not to exercise these option periods for any reason, including lack of funding, or if the agency is not satisfied with the counterparty's performance of the contract. If the U.S. government terminates any of BioVeris's contracts, BioVeris's financial condition and operating results could be materially adversely affected. In addition to unfavorable termination provisions, certain of IGEN's U.S. government contracts contain provisions that grant to the U.S. government a non-exclusive, non-transferable, irrevocable, paid-up license to use inventions made by IGEN in the course of performing such contracts, or have such inventions used by or on behalf of the U.S. government, for research or other government purposes. BioVeris will be subject to these provisions when it assumes these contracts and new U.S. government contracts entered into by BioVeris may also include similar provisions. BIOVERIS MUST OBTAIN FOOD AND DRUG ADMINISTRATION CLEARANCE OR APPROVAL TO MARKET ITS CLINICAL DIAGNOSTIC PRODUCTS, WHICH IS OFTEN COSTLY AND TIME CONSUMING. IF BIOVERIS DOES NOT OBTAIN THE NECESSARY CLEARANCES OR APPROVALS, ITS BUSINESS PROSPECTS WOULD SUFFER. The manufacture, packaging, labeling, advertising, promotion, distribution and sale of medical devices such as clinical diagnostic products are subject to governmental regulation by national and local government agencies in the United States and abroad. The U.S. Food and Drug Administration, or FDA, regulates many of the areas in which BioVeris conducts its research and in which BioVeris is and expects to be developing, manufacturing and marketing products. In particular, BioVeris must obtain FDA clearance or approval before it can market clinical diagnostic products, such as those in development for the clinical point-of-care market segment. The process of obtaining necessary clearances or approvals is often costly, time consuming and uncertain. In addition, BioVeris may begin to distribute reagents specifically for research use under an exemption. If the FDA disagrees with BioVeris's classification of, or the manner in which BioVeris markets and sells, those reagents, it may impose restrictions on BioVeris's business operations and subject BioVeris to sanctions that could adversely affect its business prospects. BioVeris has very limited experience obtaining FDA clearance and approval and may not be successful in obtaining FDA clearance or approval for any of its clinical diagnostic products, which would materially adversely affect its business prospects. Further, clearance or approval may place substantial restrictions on the indications for which the product may be marketed or to whom it may be marketed. To obtain permission from the FDA to market in the U.S., BioVeris, or the companies with which BioVeris works, will need to either obtain Section 510(k) pre-market notification clearance or approval of a pre-market approval application from the FDA. To obtain clearance for marketing, BioVeris, or the companies with which BioVeris works, must demonstrate substantial equivalence to a similar legally marketed product by submitting a pre-market notification to the FDA. The FDA may require preclinical and clinical data to support a substantial equivalence determination. Clinical trials for gathering supporting data can take extended periods of time to complete and there can be no assurance that the FDA will find a device substantially equivalent. If BioVeris does not successfully demonstrate substantial equivalence, or if BioVeris is required to obtain pre-market approval, BioVeris would have to conduct extensive clinical testing of these products, which could take years to complete. Extensive testing could involve substantial additional costs and might delay bringing clinical diagnostic products to market, weakening BioVeris's competitive position. If 34 BioVeris fails to obtain FDA clearance or approval for new products altogether, BioVeris will be unable to market these products at all for clinical use in the U.S. BIOVERIS IS SUBJECT TO COMPREHENSIVE GOVERNMENT REGULATION, WHICH MAY INVOLVE SIGNIFICANT COSTS AND MAY RESTRICT ITS ABILITY TO CONDUCT BUSINESS. BioVeris expects that certain of its future products will be subject to continuing FDA requirements, including compliance with the FDA's Good Manufacturing Practices and the FDA's medical device reporting regulation. BioVeris expects that it may need to spend a substantial amount of money to comply on an ongoing basis with government regulations. Government agencies, such as the FDA, Department of Homeland Security, Department of Commerce and the Environmental Protection Agency, or EPA, regulate many of BioVeris's products as well as products that BioVeris plans to develop, manufacture, market and sell, including products for the clinical diagnostics, biodefense and industrial markets. The costs of complying with governmental regulations and any restrictions that government agencies might impose could have a significant impact on BioVeris's business. If BioVeris increases its manufacturing and expands its product offerings, these costs will increase. Whether BioVeris manufactures products itself or contracts with another company to manufacture products based on its technology, the FDA and other government agencies will continually review and periodically inspect the manufacturing process. If any of these agencies were to discover a problem with BioVeris's products, the manufacturing process or the manufacturing facility, they could place restrictions on these products and on the manufacturer and impose sanctions. For example, the FDA could require BioVeris to recall, or even totally withdraw, a product from the market or close a manufacturing facility. In addition to FDA regulations, the process of manufacturing products is subject to a variety of environmental laws and regulations, including laws and regulations governing the use, management and disposal of hazardous, radioactive and infectious materials and wastes, the discharge of pollutants into the air and water, and the cleanup of contaminated sites. BioVeris could incur substantial costs, including cleanup costs, fines and penalties, claims for damages, such as personal injury or property damages, and loss of permits required for its operations, if it fails to comply with these laws or regulations. BioVeris's operations are also subject to various employee health and safety laws and regulations, including those concerning occupational injury and illness and employee exposure to hazardous, radioactive and infectious materials. While BioVeris has procedures in place to protect employees from exposure to such materials, it cannot assure you that potentially harmful exposure will not occur or that it will not be liable to employees as a result. In addition, because of the limited information currently available regarding some of the hazardous, radioactive and infectious materials used in BioVeris's businesses, there may be unknown risks involved with the use of and exposure to such materials. In some circumstances there may be no body of knowledge or standard protocols for dealing with these risks. Costs associated with such environmental, health and safety matters could have a material adverse effect on BioVeris's business and financial condition. In addition, in connection with BioVeris's biodefense business, the DOD or other government agencies may require additional security measures to be implemented at BioVeris's facility, which could cause BioVeris to incur substantial additional costs. BIOVERIS'S BUSINESS COULD BE ADVERSELY AFFECTED BY A NEGATIVE AUDIT BY THE U.S. GOVERNMENT. U.S. government agencies routinely audit and investigate government contractors. These agencies review a contractor's performance under its contracts. If an audit results in a finding of improper activities, BioVeris may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government. In addition, BioVeris could suffer serious harm to its business reputation if allegations of impropriety were made against it. 35 COST OVER-RUNS ON CONTRACTS WITH THE U.S. GOVERNMENT COULD SUBJECT BIOVERIS TO LOSSES OR ADVERSELY AFFECT ITS FUTURE BUSINESS. The U.S. government contracts that BioVeris intends to assume from IGEN are fixed-price contracts and therefore BioVeris will receive a fixed price irrespective of the actual costs it incurs in connection with the performance of such assumed contract. Consequently, BioVeris will be required to absorb any costs in excess of the fixed price that may be set forth in the contract. If BioVeris is unable to control the costs it incurs in performing under these contracts, its financial condition and operating results could be materially adversely affected. Cost over-runs also may adversely affect BioVeris's ability to sustain its performance under the contract and obtain future U.S. government contract awards. RESTRICTIONS ON HEALTHCARE COSTS AND HEALTHCARE AND INSURANCE FINANCING PRACTICES COULD LIMIT DEMAND FOR BIOVERIS'S PRODUCTS, WHICH WOULD HURT BIOVERIS'S BUSINESS AND BUSINESS PROSPECTS. In the U.S. and elsewhere, demand for clinical diagnostic testing is dependent, in part, on consumers' ability to be reimbursed for the cost of the tests by third-party payers, such as government agencies, health maintenance organizations and private insurers. Medicaid and other third-party payers are increasingly challenging the prices charged for medical services, including clinical diagnostic tests. They are also attempting to contain costs by limiting their coverage of, and the amount they will reimburse for, clinical diagnostic tests and other healthcare products. Without adequate coverage and reimbursement, consumer demand for clinical diagnostic tests may decrease. Decreased demand would likely cause potential sales of BioVeris's clinical diagnostic products, and sales by BioVeris's licensees, to decrease because fewer tests would be performed or prices would be lowered, or both. Reduced sales or royalty income would hurt BioVeris's business and business prospects. In many foreign markets, governments directly set the prices that clinical diagnostic companies may charge for their products and services. In the U.S., a number of legislative and regulatory proposals aimed at changing the healthcare system have been proposed in recent years and BioVeris expects this to continue. Foreign and domestic legislative and regulatory initiatives that limit healthcare coverage may have a material adverse effect on BioVeris's business and business prospects. RISKS RELATING TO THE INDUSTRY BIOVERIS IS EXPOSED TO PRODUCT LIABILITY RISKS THAT, IF NOT ADEQUATELY COVERED BY INSURANCE, MAY HAVE A MATERIAL ADVERSE EFFECT ON ITS FINANCIAL CONDITION. Product liability is a major risk in marketing products for the clinical diagnostics, biodefense and industrial markets. BioVeris may not be able to insure adequately against risk of product liability. BioVeris may face product liability for claims and lawsuits brought by customers. Damages awarded in product liability cases can be very large. While BioVeris has product liability insurance, this coverage is limited. BioVeris may not have adequate product liability insurance to cover it against its potential liabilities or be able to maintain current levels of product liability insurance on acceptable terms, if at all. Claims or losses in excess of BioVeris's product liability insurance coverage or not covered by BioVeris's product liability insurance could have a material adverse effect on its financial condition. RISKS RELATING TO BIOVERIS COMMON STOCK BIOVERIS'S EXECUTIVE OFFICERS AND DIRECTORS EXERCISE SIGNIFICANT INFLUENCE OVER BIOVERIS AND MAY HAVE SIGNIFICANT INFLUENCE OVER THE OUTCOME OF PROPOSED CORPORATE ACTIONS SUPPORTED OR OPPOSED BY OTHER BIOVERIS STOCKHOLDERS. Upon completion of the merger and related transactions, BioVeris's executive officers and directors in the aggregate, will own approximately 23.2% of the outstanding shares of BioVeris common stock. Upon completion of the merger, BioVeris's chairman and chief executive officer will own approximately 17.8% of the outstanding shares of BioVeris common stock, BioVeris's president and chief operating officer will own approximately 4.2% of the outstanding shares of BioVeris common stock and BioVeris's other directors and executive officers will own approximately 1.2% of the outstanding shares of BioVeris common stock. As a 36 result, certain of BioVeris's executive officers or directors may have significant influence over the election of directors and may be able to significantly influence the outcome of proposed corporate actions supported or opposed by other BioVeris stockholders. In addition, as a result of their shareholdings, certain of BioVeris's executive officers and directors could have significant influence over the outcome of potential transactions, including acquisition transactions, that may be supported by other BioVeris stockholders. PROVISIONS IN BIOVERIS'S CHARTER DOCUMENTS MAY DISCOURAGE POTENTIAL ACQUISITIONS OF BIOVERIS, EVEN THOSE WHICH THE HOLDERS OF A MAJORITY OF BIOVERIS COMMON STOCK MAY FAVOR, WHICH MAY ADVERSELY AFFECT THE MARKET PRICE OF BIOVERIS COMMON STOCK, REDUCE THE LIKELIHOOD OF OFFERS TO ACQUIRE BIOVERIS AND PREVENT CHANGES IN BIOVERIS'S MANAGEMENT. BioVeris's certificate of incorporation and by-laws contain provisions that may have the effect of discouraging a third party from acquiring BioVeris by means of a tender offer, proxy contest or otherwise. BioVeris's certificate of incorporation and by-laws: - classify the BioVeris board of directors into three classes, with directors of each class serving for a staggered three-year period; - provide that BioVeris's directors may be removed only for cause and only upon the approval of the holders of at least a majority of the voting power of all BioVeris's shares entitled to vote generally in the election of such directors then outstanding, voting together as a single class; - prohibit BioVeris stockholders from calling special meetings and prohibit action by BioVeris stockholders by written consent; - require at least 66 2/3% of the voting power of all BioVeris shares entitled to vote generally in the election of directors then outstanding, voting together as a single class, to alter, amend or repeal certain provisions, including the provisions relating to BioVeris's classified board, the election, appointment and removal of BioVeris's directors and action by stockholders by written consent described above; - permit the BioVeris board of directors to fill vacancies and newly created directorships on the BioVeris board of directors; and - contain advance notice requirements for stockholder proposals. In addition, under BioVeris's certificate of incorporation, the BioVeris board of directors also has the authority to issue up to 15,000,000 shares of preferred stock in one or more series. The BioVeris board of directors can fix the powers, preferences and rights of any such series without stockholder approval. The BioVeris board of directors could, therefore, issue, without stockholder approval, preferred stock with voting and other rights that could adversely affect the voting power of the holders of BioVeris common stock or otherwise make it more difficult for a third party to gain control of BioVeris. Such provisions would make the removal of incumbent directors more difficult and time-consuming and may have the effect of discouraging a tender offer or other takeover attempt not previously approved by the BioVeris board of directors. In addition, BioVeris intends to adopt a stockholder rights agreement prior to the completion of the merger, pursuant to which one BioVeris right will attach to each share of BioVeris common stock outstanding. The BioVeris rights will in most cases cause substantial dilution to a person that attempts to acquire or merge with BioVeris without the approval of the BioVeris board of directors by permitting the holders of the BioVeris rights (other than the person attempting to acquire or merge with BioVeris) to, upon the occurrence of specified circumstances, purchase, at a substantial discount, shares of BioVeris series A participating cumulative preferred stock or shares of common stock of the person that attempts to acquire or merge with BioVeris. Accordingly, the existence of the BioVeris rights may deter potential acquirors from making a takeover proposal or a tender offer. For further description of the stockholder rights plan, see "Description of BioVeris Capital Stock -- Rights Agreement." 37 THERE IS CURRENTLY NO PUBLIC TRADING MARKET FOR THE SHARES OF BIOVERIS COMMON STOCK, AND THERE IS NO ASSURANCE THAT AN ACTIVE PUBLIC TRADING MARKET WILL DEVELOP. BioVeris is unable to predict the trading price for its common stock. Although BioVeris common stock has been approved for quotation on The NASDAQ National Market(R), an active public trading market for BioVeris common stock may not develop or be sustained after the completion of the merger, which could affect your ability to sell shares of BioVeris common stock and may depress the market price of BioVeris common stock. BIOVERIS'S STOCK PRICE MAY BE VOLATILE AND COULD DROP PRECIPITOUSLY AND UNEXPECTEDLY. BioVeris common stock has been approved for quotation on The NASDAQ National Market(R). The prices of publicly traded stocks often fluctuate. The price of BioVeris common stock may rise or fall dramatically, without any change in BioVeris's business performance. In the past, the stock price of technology companies has been especially volatile. BioVeris expects that this will continue to be the case. For example, from January 1, 2003 until December 29, 2003, the NASDAQ Biotechnology Index has ranged from a low of 467.46 to a high of 801.40. In addition to these fluctuations, an investment in BioVeris common stock could be affected by a wide variety of factors that relate to BioVeris's businesses and industry, many of which are outside of its control. For example, the price of BioVeris common stock could be affected by: - new product introductions by BioVeris, its licensees or its competitors; - innovations by BioVeris's competitors; - BioVeris's competitors' announcements of their financial results; - changes in BioVeris's financial estimates and recommendations by security analysts relating to BioVeris, its licensees or its competitors; - disputes over patents or other rights relied on by BioVeris; - publicity relating to BioVeris, its licensees or its competitors; - regulations affecting BioVeris, its licensees, its industry or the customers to which BioVeris sells its products; - issuances of BioVeris common stock or other BioVeris capital stock, or securities exercisable for or convertible into BioVeris capital stock; - economic, business and other market conditions; and - fluctuations in BioVeris's performance and the performance of its licensees. In addition, if BioVeris's revenues or financial results in any period fail to meet the investment community's expectations, there could be an immediate adverse impact on BioVeris's stock price. Upon the completion of the merger and related transactions, Mr. Samuel Wohlstadter is expected to hold 4,761,437 shares, or 17.8% of the outstanding shares of BioVeris common stock and Dr. Richard Massey is expected to hold 1,118,955, or 4.2% of the outstanding shares of BioVeris common stock. Although Mr. Samuel Wohlstadter and Dr. Massey have no intention to sell a substantial number of shares of BioVeris common stock, their shares will not be subject to a lock-up agreement and may be sold in the public market in accordance with applicable securities laws. The market price of BioVeris common stock could decline as a result of sales of a substantial number of shares of BioVeris common stock or the perception that these sales could occur. In addition, the sale of shares of BioVeris common stock by Mr. Samuel Wohlstadter or Dr. Massey could impair the ability of BioVeris to raise capital through the sale of additional shares of BioVeris common stock or other securities convertible into shares of BioVeris common stock in the future. BIOVERIS DOES NOT PLAN TO PAY ANY CASH DIVIDENDS ON BIOVERIS COMMON STOCK. BioVeris has no plans to pay cash dividends on BioVeris common stock in the foreseeable future, if at all. 38 BIOVERIS MAY NEED TO RAISE ADDITIONAL CAPITAL IN THE FUTURE AND BIOVERIS MAY GRANT OPTIONS OR OTHER EQUITY-BASED AWARDS TO ITS EXECUTIVE OFFICERS, DIRECTORS, EMPLOYEES AND CONSULTANTS, FROM TIME TO TIME, EITHER OF WHICH WOULD RESULT IN DILUTION TO BIOVERIS STOCKHOLDERS. Your investment in BioVeris common stock could be diluted if BioVeris issues additional shares of BioVeris common stock or securities convertible into, or exercisable for, shares of BioVeris common stock in the future, which BioVeris may need to do to raise funds for its business. Sales of additional shares of BioVeris common stock or the conversion of securities into, or the exercise of securities for, shares of BioVeris common stock could cause the market price of BioVeris common stock to decrease. Under the BioVeris 2003 stock incentive plan, if approved, BioVeris's executive officers, directors, employees and consultants may from time to time be granted options or other equity-based awards, such as phantom stock or restricted stock, to purchase up to 5.3 million shares of BioVeris common stock. If BioVeris's executive officers, directors, employees and consultants exercise their options or other equity based awards, if and when granted and exercisable, and purchase shares of BioVeris common stock, your investment in BioVeris common stock will be diluted. THE EXON-FLORIO ACT MAY INHIBIT POTENTIAL ACQUISITION BIDS, WHICH MAY ADVERSELY AFFECT THE MARKET PRICE OF BIOVERIS COMMON STOCK. Section 721 of Title VII of the Defense Production Act of 1950, also known as the Exon-Florio Act, authorizes the president of the U.S. or his designees to initiate an investigation into the potential effects on national security of a business combination of a U.S. corporation and a foreign entity that could result in foreign control of the U.S. corporation. Subject to certain exceptions, under the Exon-Florio Act, the president may suspend or prohibit any foreign acquisition, merger or takeover of a U.S. corporation if there is credible evidence that the foreign entity exercising control might take action that threatens national security and there is no provision of law adequate to protect national security. Due to BioVeris's current and potential future involvement in the biodefense industry, the Exon-Florio Act could inhibit potential acquisition bids from foreign entities, which could adversely affect the market price of BioVeris common stock. 39 THE SPECIAL MEETING This proxy statement/prospectus is being furnished to IGEN stockholders as of the record date for the special meeting as part of the solicitation of proxies by the IGEN board of directors for use at the special meeting. DATE, TIME AND PLACE The special meeting of IGEN stockholders will be held on February , 2004, at 10:00 a.m., local time, at . PURPOSE OF THE SPECIAL MEETING At the special meeting, holders of IGEN common stock will be asked to consider and vote upon a proposal to adopt the merger agreement, to consider and vote upon a proposal to approve the proposed BioVeris 2003 stock incentive plan and to transact any other business that properly comes before the special meeting or any adjournment or postponement of the special meeting. Holders of IGEN common stock are not being asked to vote on the restructuring. If the merger agreement is adopted and the merger and related transactions are subsequently completed, each outstanding share of IGEN common stock (other than shares held by stockholders who validly exercise appraisal rights) will be converted into the right to receive $47.25 in cash, without interest, and one share of BioVeris common stock. Shares held as treasury stock and shares held by Roche or the merger sub will be canceled and retired and will cease to exist and no consideration will be delivered in exchange for these shares. RECOMMENDATIONS OF THE IGEN BOARD OF DIRECTORS The IGEN board of directors has unanimously determined that the merger agreement is advisable and in the best interests of IGEN and its stockholders. The IGEN board of directors has unanimously approved the merger agreement and related transactions and unanimously recommends that IGEN stockholders vote "FOR" the adoption of the merger agreement. Holders of IGEN common stock are not being asked to vote on the restructuring. The IGEN board of directors also unanimously recommends that IGEN stockholders vote "FOR" the approval of the proposed BioVeris 2003 stock incentive plan. RECORD DATE; SHARES ENTITLED TO VOTE; QUORUM Only holders of record of IGEN common stock at the close of business on December 18, 2003, the record date for the special meeting, are entitled to notice of, and to vote at, the special meeting. On the record date for the special meeting, 24,986,546 shares of IGEN common stock were issued and outstanding. Holders of record of IGEN common stock on the record date for the special meeting are entitled to one vote per share on each matter submitted to a vote at the special meeting. A quorum will be present at the special meeting if a majority of all the shares of IGEN common stock outstanding on the record date for the special meeting and entitled to vote at the special meeting are represented at the special meeting in person or by proxy duly authorized. If a quorum is not present at the special meeting, it is expected that the special meeting will be adjourned or postponed to solicit additional proxies. VOTES REQUIRED The adoption of the merger agreement requires the affirmative vote of stockholders holding a majority of the shares of IGEN common stock outstanding on the record date for the special meeting. The failure by the holder of any outstanding shares of IGEN common stock to either submit a proxy or vote in person at the special meeting will have the same effect as a vote against the adoption of the merger agreement 40 because the required vote of IGEN stockholders is based upon the number of outstanding shares of IGEN common stock, rather than upon the number of shares actually voted. The approval of the proposed BioVeris 2003 stock incentive plan requires the vote of a majority of the votes cast, excluding abstentions, at the special meeting at which a quorum is present The failure by the holder of any outstanding shares of IGEN common stock to either submit a proxy or vote in person at the special meeting will have no effect on the approval of the proposed BioVeris 2003 stock incentive plan. Assuming the 2003 BioVeris stock incentive plan is approved, under the National Association of Securities Dealers' marketplace rules, the BioVeris board of directors may not materially increase the numbers of shares authorized and reserved for issuance under the 2003 BioVeris stock incentive plan without further stockholder approval. SHARE OWNERSHIP OF IGEN DIRECTORS, EXECUTIVE OFFICERS AND AFFILIATES At the close of business on the record date for the special meeting, IGEN's directors and executive officers and their respective affiliates beneficially owned and were entitled to vote 5,368,318 shares of IGEN common stock, which represented approximately 21% of the shares of IGEN common stock outstanding on that date. PROXIES All shares represented by duly authorized proxies received in time for the special meeting will be voted at the special meeting in the manner specified by the holders of those proxies. Duly authorized proxies that do not contain voting instructions will be voted "FOR" the adoption of the merger agreement and "FOR" the approval of the proposed 2003 BioVeris stock incentive plan. Shares of IGEN common stock represented at the special meeting but not voting, including shares representing abstentions or broker non-votes, will be treated as present at the special meeting for purposes of determining the presence or absence of a quorum for the transaction of all business. Brokers who hold shares of IGEN common stock in "street name" for customers who are the beneficial owners of such shares may not give a proxy to vote those customers' shares without specific instructions from those customers. These non-voted shares are referred to as "broker non-votes" and count as votes against the adoption of the merger agreement and do not count for any purpose in determining the approval of the proposed BioVeris 2003 stock incentive plan. ACCORDINGLY, IF YOUR SHARES ARE HELD IN THE NAME OF A BANK OR BROKER, PLEASE FOLLOW THE INSTRUCTIONS YOU RECEIVE ON YOUR PROXY CARD TO ENSURE YOUR SHARES ARE PROPERLY VOTED AT THE MEETING. Because the adoption of the merger agreement requires the affirmative vote of stockholders holding a majority of the shares of IGEN common stock outstanding on the record date for the special meeting, abstentions, failures to vote and broker non-votes will count as votes against the adoption of the merger agreement, but will have no effect on the approval of the proposed BioVeris 2003 stock incentive plan. The persons named as proxies by a stockholder may propose and vote for one or more adjournments of the special meeting, including adjournments to permit further solicitations of proxies. No proxy voted against the proposal to adopt the merger agreement will be voted in favor of any such adjournment or postponement. IGEN does not expect that any matter other than the proposal to adopt the merger agreement and the proposal to approve the proposed BioVeris 2003 stock incentive plan will be brought before the special meeting. If, however, the IGEN board of directors properly presents other matters, the persons named as proxies will vote in accordance with their judgment unless authority to do so is withheld on the proxy card. 41 REVOCATION OF PROXIES The grant of a proxy pursuant to this solicitation does not preclude a stockholder from voting in person at the special meeting. A stockholder may revoke a proxy at any time prior to its exercise by: - notifying the Secretary of IGEN in writing that the proxy has been revoked; - submitting a new proxy bearing a later date, including a proxy given by telephone or over the Internet; or - appearing at the special meeting and voting in person, if such stockholder is a record holder. Attendance at the special meeting will not in and of itself constitute revocation of a proxy. If a stockholder chooses either of the first two methods, the new proxy or the notice of revocation, as the case may be, must be submitted to IGEN at 16020 Industrial Drive, Gaithersburg, Maryland 20877, Attention: Secretary. SOLICITATION OF PROXIES IGEN will bear the cost of the solicitation of proxies from its stockholders. In addition to solicitation by mail, the directors, officers and employees of IGEN may solicit proxies from stockholders by telephone or other electronic means or in person. IGEN will make arrangements with brokerage houses and other custodians, nominees and fiduciaries for the forwarding of solicitation materials to the beneficial owners of stock held of record by these persons. IGEN will reimburse these custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses in doing so. Georgeson Shareholder Communications, Inc., a company that provides proxy solicitation services, will assist in the solicitation of proxies by IGEN. IGEN will pay Georgeson Shareholder Communications, Inc. a fee of $12,500, plus customary additional payments for telephone solicitations and reimbursement of certain out-of-pocket expenses, and will indemnify Georgeson Shareholder Communications, Inc. against certain liabilities arising out of its proxy solicitation services on behalf of IGEN. IGEN STOCKHOLDERS SHOULD NOT RETURN ANY STOCK CERTIFICATES WITH THEIR PROXY CARDS. After the merger is completed, IGEN stockholders will be sent a transmittal form with instructions for the surrender of IGEN common stock certificates. 42 THE COMPANIES AND THE LITIGATION ROCHE Roche is one of the world's leading innovation-driven healthcare groups. Roche's core businesses are pharmaceuticals and diagnostics. Roche is one of the world's leading providers of diagnostic systems, one of the leading suppliers of pharmaceuticals for cancer and a leader in virology and transplantation. As a supplier of products and services for the prevention, diagnosis and treatment of disease, Roche contributes on a broad range of fronts to improving people's health and quality of life. Roche employs approximately 65,000 people in 150 countries around the world. Roche was organized in Switzerland in 1895. The address of Roche's principal executive offices is Grenzacherstrasse 124, CH-4070, Basel, Switzerland, and its telephone number is (+41) 61-688-8880. IGEN IGEN and its licensees develop, manufacture and market products based on IGEN's ECL technology. IGEN believes that its ECL technology, which detects and measures biological substances, offers significant advantages over competing detection and measurement methods by providing a unique combination of speed, sensitivity, flexibility and throughput in a single technology platform. ECL technology is incorporated into IGEN's and its licensees' instrument systems and reagents, which are the biological and chemical compounds that are used to perform a test, or assay, on such instrument systems. IGEN was incorporated in California in 1982 as IGEN, Inc., and on November 19, 1996, IGEN, Inc. merged into IGEN International, Inc., a newly-formed Delaware corporation. The address of IGEN's principal executive offices is 16020 Industrial Drive, Gaithersburg, Maryland 20877, and its telephone number is (301) 869-9800. BIOVERIS BioVeris is a newly-formed, wholly-owned subsidiary of IGEN. As part of the restructuring, BioVeris will assume IGEN's biodefense, life science and industrial product lines, as well as IGEN's opportunities in the clinical diagnostics and healthcare fields, and will own IGEN's intellectual property, IGEN's equity interest in MSD, a company formed by IGEN and MST, which is a company established and wholly-owned by Mr. Jacob Wohlstadter, a son of IGEN's and BioVeris's chairman and chief executive officer, cash and certain other rights and licenses currently held by IGEN. Simultaneously with the completion of the merger, certain ongoing commercial agreements between BioVeris and certain affiliates of Roche will become effective. BioVeris's strategy is based on the direct development and sale of its products utilizing its technologies, while at the same time entering into collaborations with third parties that can assist BioVeris in its product development, manufacturing and marketing efforts. Key elements of BioVeris's strategy are to: - pursue collaborative relationships to accelerate new product development and enhance global manufacturing and marketing capabilities; - establish leadership positions in emerging markets; and - develop and market product line extensions and an expanded menu of assays. BioVeris was organized as a Delaware limited liability company on June 6, 2003 as IGEN Integrated Healthcare, LLC, and on September 22, 2003, IGEN Integrated Healthcare, LLC was converted into BioVeris Corporation, a newly-formed Delaware corporation. The address of BioVeris's principal executive offices is 16020 Industrial Drive, Gaithersburg, Maryland 20877, and its telephone number is (301) 869-9800. 43 THE LITIGATION Since 1997, IGEN and Roche have been involved in a lawsuit in the District Court relating to, among other things, IGEN's ability to terminate a license agreement for ECL technology that was granted in 1992 to a company that became a subsidiary of Roche. On July 9, 2003, the Appellate Court, among other things, affirmed IGEN's right to terminate the license while vacating the $400 million punitive damage award against the subsidiary of Roche and reversing $86.8 million of the compensatory damage award against the subsidiary of Roche. This lawsuit is referred to in this proxy statement/prospectus as the Roche litigation. In addition, on July 9, 2003, IGEN sent a notice to the subsidiary of Roche confirming termination of the license and filed patent infringement lawsuits against the subsidiary in Maryland and Germany. These lawsuits have been stayed by agreement of the parties pending completion of the merger. 44 THE MERGER AND RELATED TRANSACTIONS BACKGROUND TO THE MERGER AND RELATED TRANSACTIONS In 1992, IGEN entered into a license agreement with Boehringer Mannheim GmbH, which is referred to in this proxy statement/prospectus as the 1992 license agreement, for the development, use, manufacture and sale of ECL-based clinical immunoassay and nucleic acid test systems in certain defined fields specified in the 1992 license agreement. Beginning in 1996, disputes began to arise between IGEN and Boehringer Mannheim regarding the proper interpretation of, and Boehringer Mannheim's compliance with, the 1992 license agreement. In May 1997, Roche agreed to acquire Boehringer Mannheim. In August 1997, IGEN engaged Lehman Brothers Inc., or Lehman Brothers, as its advisor to assist IGEN and its legal advisors in assessing the value of its position and attempting to resolve the dispute between IGEN and Boehringer Mannheim and to identify opportunities and advise IGEN with respect to possible asset transfers, merger and other transactions with Boehringer Mannheim. On September 15, 1997, IGEN filed a lawsuit against Boehringer Mannheim in the District Court, alleging that, among other things, Boehringer Mannheim failed to perform certain material obligations under the 1992 license agreement. On that same date, Boehringer Mannheim filed suit against IGEN in the U.S. District Court for the District of Indiana asserting that IGEN had breached its contractual obligations to Boehringer Mannheim under the 1992 license agreement. From time to time in late 1997 and in 1998, representatives of IGEN, Lehman Brothers and Boehringer Mannheim (and after its acquisition of Boehringer Mannheim, Roche) discussed a number of potential options for a possible settlement. No agreement was reached. In December 1997, IGEN International KK, or IGEN KK, a Japanese subsidiary of IGEN, filed a lawsuit in Tokyo District Court, Tokyo, Japan against Hitachi, Ltd. or Hitachi. This lawsuit is referred to in this proxy statement/prospectus as the Tokyo litigation. In the Tokyo litigation, IGEN KK sought to enjoin Hitachi from infringing its intellectual property rights relating to ECL technology and to prevent Hitachi from manufacturing, using or selling the Elecsys 2010 instrument in Japan. Hitachi was the sole manufacturer for Roche of that instrument. In March 1998, Roche completed its acquisition of Boehringer Mannheim and renamed the company Roche Diagnostics. Also in March 1998, IGEN and Roche Diagnostics agreed that Roche Diagnostics would voluntarily dismiss the lawsuit it previously filed in Indiana and that the litigation between them would proceed in the District Court. In connection with that agreement, IGEN stipulated that it would not terminate the 1992 license agreement unless and until the Appellate Court, confirmed it was entitled to do so. In the Roche litigation, IGEN alleged that Roche Diagnostics breached material obligations under the 1992 license agreement, including that Roche Diagnostics failed to develop and commercialize ECL technology according to the contractual timetable, failed to exploit the license to the extent contemplated by the parties, failed to phase out certain non-royalty-bearing product lines, exploited ECL technology outside of the fields specified in the 1992 license agreement, failed to properly treat intellectual property rights regarding ECL technology, failed to maintain records essential to the computation of royalties, and failed to properly compute royalties. In the lawsuit, IGEN sought compensatory damages as well as injunctive and declaratory relief, including a judicial declaration of its right to terminate the 1992 license agreement. Roche Diagnostics filed counterclaims against IGEN alleging that, among other things, IGEN breached its obligations under the 1992 license agreement by permitting other licensees to exercise certain rights to ECL technology, by failing to share certain improvements to ECL technology with Roche Diagnostics and by declining to defend Roche Diagnostics in the Serono litigation described below. Roche Diagnostics also alleged that IGEN had misrepresented its own intentions with respect to the expansion of rights granted to Eisai Co., Ltd., which is referred to in this proxy statement/prospectus as Eisai, under a 45 separate license agreement. Roche Diagnostics further alleged that IGEN breached the 1992 license agreement and had interfered with its business relationships by filing the Tokyo litigation. In June 1998, Laboratorios Serono S.A., a subsidiary of Ares-Serono S.A., or Serono, filed a patent infringement claim against IGEN, Roche Diagnostics, Roche Diagnostics Corporation and bioMerieux (formerly Organon Teknika) in the U.S. District Court for the District of Delaware. Serono claimed that a Serono patent was infringed by the parties. F. Hoffmann-La Roche Ltd subsequently acquired the patent from Serono and continued in Serono's place to assert infringement against IGEN and bioMerieux. This lawsuit against IGEN is referred to in this proxy statement/prospectus as the Serono litigation. In August 1998, senior executives from IGEN met for the first time with Dr. Franz Humer, chief executive officer of Roche, as well as other senior executives of Roche in Basel, Switzerland to discuss a possible settlement of the Roche litigation. Although the parties discussed various settlement options, no agreement was reached. On October 19, 1998, the District Court issued a preliminary injunction, following a motion by IGEN earlier in the year, prohibiting Roche Diagnostics from marketing its Elecsys products in physicians' office laboratories and requiring Roche Diagnostics to escrow all revenues from past sales to physicians' office laboratories pending the outcome of the Roche litigation and to transfer all of its current Elecsys customers constituting physicians' office laboratories to IGEN. From time to time in 1999 through January 2001, representatives of IGEN and representatives of Roche held meetings and discussions regarding a possible settlement of the Roche litigation. Although during this period IGEN and Roche discussed a number of potential options for a possible settlement, no agreement was reached. On August 18, 2000, IGEN filed an amended complaint with the District Court in the Roche litigation asserting additional breach of contract claims and a claim for unfair competition. In this amended complaint, IGEN added a request that Roche be required to pay punitive damages to IGEN. During 2001, Roche retained Merrill Lynch and The Taylor Companies to assist it in evaluating potential options for a possible resolution of the Roche litigation as well as the possibility of Roche acquiring 100% of the stock of IGEN, which is discussed below. On February 23, 2001, the trial in the Serono litigation began. The trial was completed on February 28, 2001. After post-trial briefing, the case was taken under advisement by the court. On March 5, 2001, Mr. Heino von Prondzynski, member of the Executive Committee of Roche and the Head of Roche Diagnostics, wrote to Mr. Samuel Wohlstadter regarding the possibility of Roche acquiring 100% of the stock of IGEN as a means of resolving the dispute between Roche and IGEN. On March 8, 2001, following telephone conversations between Messrs. von Prondzynski and Wohlstadter, Mr. Wohlstadter wrote to Mr. von Prondzynski indicating that an acquisition of IGEN at an appropriate price might be an attractive option for resolving the Roche litigation. IGEN requested, on advice of counsel, that Roche execute a confidentiality and standstill agreement prior to commencing more specific discussions about Roche's proposal that it acquire 100% of the stock of IGEN. At various times thereafter in March 2001 and early April 2001, Messrs. Wohlstadter and von Prondzynski discussed the execution of a confidentiality and standstill agreement and initiation of discussions regarding the economic and other major terms of Roche's proposal. They were not able to reach agreement on these preliminary matters. On March 19, 2001, the IGEN board of directors held a special meeting to consider their response to Mr. von Prondzynski's March 5, 2001 letter. Members of management described the recent conversations and contacts between representatives of IGEN and representatives of Roche. Representatives of Cravath, Swaine & Moore LLP, or Cravath, special counsel to IGEN, discussed the directors' fiduciary duties in responding to Roche's letter and answered questions from the directors. Representatives of Lehman Brothers discussed their views and preliminary analyses of the financial aspects of a possible acquisition of IGEN. Representatives of Wilmer, Cutler & Pickering, counsel to IGEN, gave a presentation regarding 46 the dispute with Roche. Representatives of Morris, Nichols, Arsht & Tunnell, counsel to IGEN, gave a presentation regarding the Serono litigation. The IGEN board of directors authorized Mr. Samuel Wohlstadter to continue discussions, including discussions regarding valuation, with Mr. von Prondzynski regarding a possible transaction subject to obtaining a confidentiality and standstill agreement executed by Roche. Roche declined to enter into this agreement. On March 26, 2001, the District Court granted IGEN's motion for summary judgment in the Roche litigation with respect to the allegation that Roche Diagnostics breached the 1992 license agreement by taking improperly calculated and unsubstantiated "rental surcharge" deductions against reported sales of royalty-bearing products. The District Court also dismissed Roche Diagnostics' counterclaims for fraud and tortious interference with its business, as well as Roche Diagnostics' related request for punitive damages. On April 6, 2001, the IGEN board of directors received a written non-binding expression of interest from Mr. von Prondzynski and Mr. Andreas Knierzinger, Head of Mergers and Acquisitions of Roche, proposing that Roche acquire 100% of IGEN's outstanding common stock for cash consideration of up to $500 million, subject to completion of due diligence. Roche's expression of interest expired by its terms at 5:00 p.m., EDT, on April 20, 2001. In response to IGEN's written request on April 19, 2001, Roche, on April 24, 2001, extended the deadline for IGEN to respond to its expression of interest until 5:00 p.m., EDT, on April 27, 2001. On April 11, 2001, Mr. Samuel Wohlstadter sent a letter to Mr. von Prondzynski to acknowledge receipt of the April 6, 2001 expression of interest and reiterate IGEN's request that Roche execute a confidentiality and standstill agreement prior to commencing discussions regarding the specific terms of Roche's proposal. On April 19, 2001, the IGEN board of directors held a special meeting at which members of management described the recent conversations between representatives of IGEN and representatives of Roche as well as the April 6, 2001 expression of interest received from Roche. The IGEN board of directors also authorized management to formally engage Lehman Brothers as IGEN's financial advisor in connection with the evaluation of proposals to acquire IGEN or an interest in IGEN. On April 25, 2001, the IGEN board of directors held a special meeting to consider the April 6, 2001 expression of interest from Roche. Members of management described the recent conversations and contacts between representatives of IGEN and representatives of Roche. Representatives of Cravath discussed the IGEN board of directors' fiduciary duties in considering Roche's expression of interest and also described the terms of Roche's expression of interest. Representatives of Lehman Brothers made a detailed financial presentation regarding Roche's expression of interest and indicated that, based on and subject to the matters to be contained in the written opinion, as of that date, from a financial point of view, the consideration which had been offered in Roche's expression of interest was inadequate to the stockholders of IGEN and Lehman Brothers would be prepared to issue an opinion in writing to that effect. Representatives of Wilmer, Cutler & Pickering gave a presentation regarding the Roche litigation. Representatives of Morris, Nichols, Arsht & Tunnell gave a presentation regarding the Serono litigation. Upon completing its deliberation, the IGEN board of directors unanimously decided to reject Roche's expression of interest. The IGEN board of directors decided, however, that if mutually acceptable terms could be reached, an acquisition transaction could still be a constructive approach to resolving the parties' dispute. On that same day, Mr. Samuel Wohlstadter advised Mr. von Prondzynski by letter of the IGEN board of directors' decision and again conveyed the IGEN board of directors' request that Roche execute an appropriate confidentiality and standstill agreement with IGEN so that further discussions could take place. From time to time during the period from May 2001 until mid-October 2001, representatives of IGEN and representatives of Roche had preliminary discussions concerning valuation and possible structures for an acquisition of IGEN by Roche. Representatives of IGEN continued to request that Roche execute an appropriate confidentiality and standstill agreement. 47 On August 10, 2001, the District Court granted two of IGEN's motions for summary judgment in the Roche litigation with respect to the allegations that Roche Diagnostics breached the 1992 license agreement by settling the Serono litigation without IGEN's consent and by failing to cease development of a competing product line. The District Court also ruled that Roche Diagnostics' field was limited solely to hospitals (with certain exceptions), clinical reference laboratories and blood banks. On October 16, 2001, Roche, Roche Diagnostics and IGEN executed a confidentiality agreement, including a standstill provision that would remain in effect for three months, which was the expected duration of the jury trial in connection with the Roche litigation. After execution of the confidentiality agreement, IGEN suggested to Roche a possible transaction structure whereby Roche would acquire 100% of IGEN, with IGEN stockholders receiving, in exchange for their IGEN stock, cash from Roche and shares of common stock of a new public company to be spun-off by IGEN. The new company would contain certain assets and liabilities of IGEN to be identified by the parties. This transaction structure is referred to in this proxy statement/prospectus as the Newco transaction. On October 24, 2001, the jury trial in connection with the Roche litigation began. In November 2001, Roche, IGEN and the remaining defendants reached a settlement of the Serono litigation. In that settlement, Roche dismissed with prejudice all claims against IGEN, paid IGEN $5.7 million as reimbursement for legal fees incurred in the Serono litigation and granted IGEN a fully-paid, perpetual, worldwide, non-exclusive license (with the right to grant sublicenses) to the patent at issue. From time to time in November and early December 2001, representatives of IGEN and Roche and their respective legal and financial advisors continued to have discussions regarding a possible Newco transaction. On December 8, 2001, representatives of the Taylor Companies informed representatives of IGEN that Roche was no longer willing to discuss a possible Newco transaction, but that Roche was prepared to discuss an acquisition of 100% of IGEN's stock for cash. On December 9, 2001, the IGEN board of directors held a special meeting at which members of management described the recent discussions between representatives of IGEN and Roche and their respective financial and legal advisors. After discussion, the IGEN board of directors authorized management to continue discussions with respect to a possible acquisition by Roche of 100% of IGEN's stock for cash. In mid-December 2001, Roche and its financial and legal advisors conducted business and legal due diligence in connection with a potential acquisition of IGEN at the offices of Wilmer, Cutler & Pickering. In addition, representatives of IGEN and Roche and their respective legal advisors exchanged drafts of a merger agreement and a stockholder agreement and continued to discuss the terms of a possible acquisition by Roche of 100% of IGEN's stock for cash. Numerous significant issues were raised in these discussions, including price, IGEN's requirements for a high level of closing certainty and Roche's requirements that certain ongoing obligations, including those related to MSD, be terminated in connection with an acquisition by Roche. These issues remained unresolved at the conclusion of the jury trial in connection with the Roche litigation referred to below. On January 3, 2002, the jury trial in connection with the Roche litigation ended, and on January 10, 2002, the jury rendered a verdict that Roche Diagnostics had breached the 1992 license agreement, had violated its duty of good faith and fair dealing to IGEN in connection with a license for nucleic acid tests and had engaged in unfair competition against IGEN, and that IGEN had violated its duty of good faith and fair dealing to Roche as a result of the prosecution of the Tokyo litigation. On February 15, 2002, the District Court issued a final order of judgment that confirmed the jury's decision awarding $105 million in compensatory damages and $400 million in punitive damages, entitling IGEN to terminate the 1992 license agreement and directing Roche Diagnostics to grant to IGEN for use in IGEN's retained fields a license to all improvements with respect to ECL technology developed by 48 Roche Diagnostics under the 1992 license agreement. Roche Diagnostics was also ordered, at its sole cost and expense, to deliver those improvements to IGEN and to provide all other information and materials required or necessary to enable IGEN to commercialize those improvements. The final order of judgment also barred Roche Diagnostics from marketing, selling, placing or distributing outside of its licensed field any products based on ECL technology, including its Elecsys diagnostics product line. The final order also found in IGEN's favor on all of Roche Diagnostics' counterclaims, except for one for which IGEN was ordered to pay $500,000, which it paid promptly. On February 20, 2002, IGEN sent a notice to Roche Diagnostics terminating the 1992 license agreement effective upon the expiration of Roche Diagnostics' time to file a notice of appeal of the District Court decision in connection with the Roche litigation, if Roche Diagnostics had not filed a notice to appeal by that time, or at such time as the Appellate Court has issued a final order concluding the appeal that did not reverse or vacate those portions of the judgment entitling IGEN to terminate the 1992 license agreement. On April 15, 2002, the District Court reaffirmed its final order of judgment. In May 2002, Roche filed notices of appeal of the final order of judgment to the Appellate Court. Roche Diagnostics appealed certain aspects of the final order of judgment to the Appellate Court. During the appeal process Roche Diagnostics was obligated to continue to comply with the terms of the 1992 license agreement, including its obligation to continue to pay IGEN royalties on Roche Diagnostics' sales of royalty bearing products and to share and deliver improvements. Roche Diagnostics' obligation to pay the $505 million of monetary damages awarded to IGEN was suspended until completion of the appeal process. On May 28 and 29, 2002, representatives of IGEN and representatives of Roche met in Washington, D.C. to continue their negotiations regarding various alternatives to resolve their dispute, but no agreement was reached. On June 13, 2002, IGEN and Hitachi settled the Tokyo litigation. In June and July 2002, the parties participated in the Appellate Court's mandated mediation program. On June 21, 2002, at the direction of the Appellate Court's senior circuit mediator, Foley & Lardner, counsel to Roche Diagnostics, sent a letter to Wilmer, Cutler & Pickering conveying a settlement proposal for the mediation session. That proposal reiterated a proposal made by Roche to IGEN during the parties' meeting on May 29, 2002. The proposal included a payment to IGEN in the amount of $250 million in settlement of all of the issues in the litigation, the acquisition of 5% of IGEN's outstanding stock from stockholders for $150 million and the payment of a fixed annual fee of $100 million per year, to the extent Roche Diagnostics in fact continued to use ECL technology, for 10 years for a worldwide, non-exclusive license for the use of ECL technology in Roche Diagnostics' field as specified in the final order of judgment. The proposal also included a supply agreement pursuant to which Roche Diagnostics would make available to IGEN, for use in IGEN's retained fields, Roche Diagnostics' products based on ECL technology as well as a continued supply of reagents comparable to those provided for in the 1992 license agreement. The parties were unable to resolve the dispute through the mediation process. Separately, in July and August 2002, IGEN and Roche exchanged drafts of, and held a series of negotiation sessions regarding, a possible settlement agreement and certain related commercial agreements to resolve the Roche litigation. On August 8, 2002, Mr. Wohlstadter and Dr. Humer met in Zurich, Switzerland and discussed various aspects of a possible settlement. On August 14, 2002, Dr. Humer sent a letter to Mr. Samuel Wohlstadter to follow up on their discussions and advise him of the critical points of any settlement offer, including an absolute maximum financial burden for Roche of $1.1 billion on a net present value basis under any possible structure. Based on conversations with representatives of Roche, representatives of IGEN understood Roche's position to mean that the cash payment by Roche in any settlement would be less than $1.1 billion due to downward adjustments resulting from any non-cash value perceived to be provided by Roche and certain unspecified costs to Roche related to the transaction structure selected. 49 During the period from August through September 2002, IGEN and Roche filed their appellate briefs in connection with Roche's appeal of the District Court's judgment. From time to time in August, September and October 2002, representatives of IGEN and Roche and their respective advisors continued to engage in discussions regarding a possible settlement and related matters. In mid-October 2002, IGEN proposed to Roche that Roche reconsider the Newco transaction structure as a means of resolving the outstanding issues. In late October, representatives of IGEN and Roche and their respective legal advisors met in New York to discuss the Newco transaction structure. At this meeting, representatives of IGEN made a presentation regarding the Newco transaction structure. Representatives of Roche indicated a willingness to consider the Newco transaction structure, but reiterated the maximum value Roche had said it would provide in any transaction structure and therefore indicated it would be Roche's position that in the Newco transaction structure the cash to IGEN stockholders and the Roche-provided funding for BioVeris would be less than $1.1 billion. IGEN's representatives indicated that, while they would not accept Roche's proposed cap on value, they were nevertheless willing to proceed with the negotiation of documentation and other terms in connection with a possible Newco transaction. As a result of the meetings, the parties began to pursue the Newco transaction structure as a framework for resolving their dispute. Representatives of Roche advised representatives of IGEN that a number of issues remained to be resolved, including obtaining the consent of MSD, to any transaction between Roche and IGEN. In late October and early November 2002, representatives of IGEN and Roche and their respective legal advisors exchanged drafts of a merger agreement, related transaction agreements and ongoing commercial agreements (including agreements by Roche to supply BioVeris with finished instruments to be marketed and sold by BioVeris and key ingredients used to produce assays) in connection with the Newco transaction structure. In early December 2002, representatives of IGEN and Roche and their respective legal advisors met again in New York to discuss and negotiate the Newco transaction structure, the terms of a possible transaction and the ongoing commercial agreements. In January 2003, representatives of IGEN and Roche and their respective legal advisors met in New York, and from time to time in January and February 2003 held a series of telephone conferences and a video conference, to discuss the Newco transaction structure, including a new proposal by IGEN regarding the Newco transaction structure designed to reduce the likelihood of future disputes regarding the commercialization of ECL technology, and to negotiate the ongoing commercial agreements. During this period, the parties exchanged various drafts of the ongoing commercial agreements. On February 24, 2003, the Appellate Court heard oral arguments on the appeal by Roche of the judgment of the District Court. From time to time in March, April and early May 2003, representatives of IGEN and Roche and their respective legal advisors met in New York and held a series of telephone conferences to discuss, and exchanged drafts of, the merger agreement, related transaction agreements, the ongoing commercial agreements and other related issues regarding a possible Newco transaction. In connection with these discussions, Roche stated that it would require that the Roche litigation be settled at the time of signing the definitive agreements relating to a Newco transaction (rather than at completion of the transaction) pursuant to a settlement agreement that would provide Roche with a new, limited license for a limited period, irrespective of whether the Newco transaction was ultimately completed. IGEN agreed to discuss this concept. During this period Roche and Davis Polk & Wardwell, or Davis Polk, legal advisors to Roche, also conducted business and legal due diligence relating to IGEN in a data room established in New York. On April 28, 2003, in connection with obtaining MSD's consent to the Newco transaction as requested by Roche, IGEN, Roche, Roche Diagnostics and MSD entered into a confidentiality agreement 50 to permit MSD to review drafts of the merger agreement, related transaction agreements and ongoing commercial agreements as well as other information relating to the Newco transaction. On May 9, 2003, the IGEN board of directors held a meeting in Washington, D.C. Representatives of Wilmer, Cutler & Pickering updated the IGEN board of directors on the status of the Roche litigation, members of management gave a detailed presentation of a proposed business plan for BioVeris and representatives of Lehman Brothers gave a detailed financial presentation relating to a possible Newco transaction. Representatives of Cravath reviewed with the IGEN board of directors the fiduciary duties of the directors in considering the possible transaction with Roche, the material terms of and the open issues in connection with the related transaction agreements and certain legal issues related to the Newco transaction structure. A representative of Hale and Dorr LLP, counsel to IGEN, reviewed the status and the material terms of the ongoing commercial agreements. From time to time in mid- to late May 2003 and early to mid-June 2003, representatives of IGEN and Roche and their respective legal advisors met in New York and held a series of telephone conferences to continue to discuss and exchange comments on various drafts of a settlement agreement, the merger agreement, the related transaction agreements and the ongoing commercial agreements, as well as to discuss the need for and possible financial terms of separate PCR license agreements. During these discussions, the parties made various proposals intended to ensure that the parties would have a high level of certainty that the Newco transaction would in fact close if definitive agreements were in fact agreed. In addition, during this period Davis Polk reviewed additional documents relating to IGEN in the data room. In late June 2003, representatives of IGEN and Roche and their respective legal advisors met again in New York to discuss various alternatives relating to closing certainty as well as various drafts of the merger agreement, related transaction agreements and ongoing commercial agreements. Davis Polk also provided an initial draft of the MSD global consent agreement. On July 3, 2003, Mr. Samuel Wohlstadter and other representatives of IGEN's senior management met with Dr. Humer and other representatives of Roche's senior management to discuss various aspects of the Newco transaction, including valuation. At that meeting, the parties once again discussed the possibility of an all-cash acquisition of 100% of IGEN's stock and Dr. Humer reiterated his previously expressed value limits. The members of IGEN senior management who attended the meeting understood that this approach would result in less than $1.1 billion being paid to IGEN stockholders. On July 8, 2003, Mr. Wohlstadter and Dr. Humer exchanged letters regarding the completion of due diligence and seeking to come to resolution on the remaining business issues, including valuation. On July 9, 2003, the Appellate Court issued its opinion in the Roche litigation. The opinion affirmed IGEN's right to terminate the 1992 license agreement, affirmed IGEN's right to certain improvements and left intact IGEN's right to receive $18.6 million in compensatory damages. The Appellate Court, however, vacated the $400 million punitive damage award against Roche and reversed $86.8 million in compensatory damages. Also on July 9, 2003, the IGEN board of directors held a special meeting at which the board evaluated the consequences of the termination of the 1992 license agreement and the status of the negotiations with Roche toward a possible transaction. Upon completing its deliberations, the IGEN board of directors authorized management to send the notice to Roche Diagnostics confirming termination of the 1992 license agreement and instructed management to file patent infringement suits against Roche Diagnostics. On the same date, IGEN sent a notice to Roche Diagnostics confirming termination of the 1992 license agreement and filed patent infringement suits against Roche Diagnostics in Maryland and Germany. On July 10, 2003, Dr. Humer sent a letter to Mr. Samuel Wohlstadter indicating that a negotiated transaction would still be in the parties' best interests and advising IGEN that Roche was considering an acquisition of 100% of IGEN's stock, subject to the parties resolving their outstanding issues in connection with the transaction, including obtaining MSD's consent. On the same date, the IGEN board of directors held a special meeting to discuss the status and timing of the discussions with Roche. Members of 51 management described the recent conversations and contacts between representatives of IGEN and representatives of Roche and discussed the expected schedule of future discussions with Roche. During the week of July 14, 2003, representatives of IGEN and representatives of Roche met in New York and discussed resolution of the remaining issues. At the outset of the meeting on July 14, 2003, Dr. Humer discussed the possibility of an all-cash acquisition of 100% of IGEN's common stock at $42.00 per share. Mr. Samuel Wohlstadter responded that he would be prepared to recommend to the IGEN board of directors an acquisition of 100% of IGEN's common stock at $62.00 per share. At the close of the meeting, Dr. Humer proposed an all-cash acquisition of 100% of IGEN's common stock at $48.00 per share and in response Mr. Samuel Wohlstadter requested $52.00 per share. Although the parties did not reach an agreement with respect to valuation, Mr. Wohlstadter and Dr. Humer agreed to instruct their respective negotiating teams to resolve all other issues during the week of July 14, 2003 and that they would meet again on July 19, 2003 to further discuss valuation. In addition, each of the parties acknowledged that there would be a high level of closing certainty along the lines previously proposed by IGEN. In addition on July 14, 2003, representatives of Roche, a representative of the joint venture oversight committee of the IGEN board of directors (a committee that consisted of three independent directors with the authority and responsibility for matters relating to MSD; on the dates described in this background to the merger and related transactions, Messrs. Anthony Rees, Robert R. Salsmans and Joop Sistermans were the members of the committee), or the JVOC, a representative of Potter Anderson & Corroon LLP, or Potter Anderson, counsel to the JVOC, and Mr. Jacob Wohlstadter met to discuss obtaining the consent of MSD and MST, which is a company established and wholly-owned by Mr. Jacob Wohlstadter and is IGEN's joint venture partner in MSD, to a transaction between Roche and IGEN. Mr. Jacob Wohlstadter had from time to time participated in previous negotiations with Roche in his capacity as a representative of MSD and to facilitate obtaining any consent of MSD or MST which Roche might require, as well as in his capacity as a consultant to IGEN. Mr. Jacob Wohlstadter proposed that in exchange for the consent of MSD and MST to the acquisition and the waiver by MSD of certain of its rights under the MSD joint venture agreement, MSD would receive continued funding as well as the assets and rights that would have been transferred to BioVeris in a Newco transaction (including a license to Roche's PCR technology), but excluding any supply agreements relating to finished instruments or key ingredients. Representatives of Roche indicated a willingness to consider MSD's proposal to receive these assets and rights. Upon learning of Mr. Jacob Wohlstadter's proposal to Roche, and Roche's willingness to consider it, representatives of IGEN met again with Roche and inquired whether Roche was prepared to pursue the Newco transaction with BioVeris receiving the assets and rights covered by that proposal without reduction of the total cash payment by Roche. Roche indicated a willingness to proceed negotiating the Newco transaction on this basis. Between July 15 and 18, 2003, the representatives of IGEN and Roche and their respective legal advisors met and held numerous telephone conferences in New York and exchanged drafts of and comments on the merger agreement, the related transaction agreements, the ongoing commercial agreements and an ongoing litigation agreement, in each case related to the Newco transaction structure. On July 15 and July 19, 2003, Mr. Jacob Wohlstadter and representatives of the JVOC and their respective legal advisors had several discussions regarding the terms under which MSD and MST would provide their consent to a possible Newco transaction. MSD's and the JVOC's respective legal advisors also exchanged drafts of the MSD consent and MSD proposed a letter agreement between IGEN, BioVeris, MSD and MST outlining certain additional matters relating to the consent. MSD's proposals contemplated that IGEN and BioVeris would pay to MSD $10 million upon execution of the consent and an additional $60 million upon the earlier of the completion of the merger or the termination of the merger agreement. In addition, MSD's proposals contemplated extensive amendments to the MSD joint venture agreement and other related agreements. Mr. Jacob Wohlstadter explained the basis for MSD's proposals, among other things stating that a change of control of IGEN would trigger a one-time payment from IGEN to MSD of $20.6 million based on IGEN's funding commitment for the period through November 30, 2003, and that the Newco transaction as contemplated would eliminate MSD's future 52 access to reagents from Roche. In response, the JVOC proposed that MSD receive no payments or other consideration in connection with the consent and further informed Mr. Jacob Wohlstadter that it was unwilling to discuss amendments to the MSD joint venture agreement and other related agreements in connection with obtaining MSD's consent. On July 19 and 20, 2003, at the invitation of the JVOC, Mr. Richard Cass, IGEN's only non-management director who was not a member of the JVOC, frequently participated in the discussions and deliberations among the JVOC regarding MSD and the possible transaction with Roche. On July 19, 2003, representatives of IGEN and Roche and their respective legal advisors met in New York and discussed and negotiated valuation and other open issues. Mr. Samuel Wohlstadter and Dr. Humer then met and agreed that, if MSD's and MST's consents could be obtained and the documentation finalized to the mutual satisfaction of the parties, Roche would provide $52.00 of value to be allocated as IGEN desired between a direct payment to IGEN stockholders and funding for BioVeris, as well as an additional $50 million of funding for BioVeris. Following their meeting, Mr. Samuel Wohlstadter and Dr. Humer instructed their respective negotiating teams to resolve the remaining issues promptly. From July 19 through 23, 2003, representatives of IGEN and Roche and their respective legal advisors continued to conduct negotiations to finalize the PCR license agreements. On July 20, 2003, Cravath distributed revised drafts of the merger agreement and related transaction agreements to Roche, Davis Polk, MSD and its legal advisors and IGEN's other legal advisors. Also on July 20, 2003, representatives of Roche and its legal advisors met in New York and Davis Polk provided representatives of IGEN and its legal advisors with comments on the revised merger agreement and related transaction agreements. Representatives of IGEN and Roche and their respective legal advisors continued to discuss the remaining non-valuation issues. Also on July 20, 2003, Mr. Jacob Wohlstadter and representatives of the JVOC and their respective legal advisors had a telephone conference to discuss MSD's proposed changes to the MSD consent and the proposed MSD letter agreement. That afternoon, Mr. Jacob Wohlstadter revised his requested consent payment downward to a one-time payment of $37.5 million, plus the payment by BioVeris of all of MSD's and MST's expenses in connection with the merger and consent, which Mr. Jacob Wohlstadter estimated at $2.5 million through July 31, 2003. That same day, the JVOC made a counter-offer that BioVeris would provide additional funding to MSD of $30 million, of which $20.6 million would be payable upon completion of the proposed transaction with Roche and $9.4 million payable six months thereafter, and that the MSD joint venture agreement would expire upon the first to occur of the completion of the merger or the termination of the merger agreement. The JVOC rejected substantially all the changes to the MSD joint venture agreement and other related agreements being requested by Mr. Jacob Wohlstadter. These discussions continued on July 21 and 22, 2003, and MSD and the JVOC and their respective legal advisors exchanged revised drafts of the MSD consent and MSD letter agreement, and Mr. Jacob Wohlstadter provided the JVOC with written materials explaining his position, including that he had already made a number of significant concessions based on the position of the JVOC. Later on July 20, 2003, the IGEN board of directors held a special meeting at which management updated the directors on the status of their discussions with Roche and the JVOC updated the directors on the discussions with Mr. Jacob Wohlstadter and described the proposal that the JVOC made to Mr. Jacob Wohlstadter earlier that day. The IGEN board of directors discussed various alternatives in the event an agreement could not be reached with MSD and MST for their consent. On July 21, 2003, the JVOC met with Mr. Samuel Wohlstadter and told him the JVOC would not agree to increase the additional funding for MSD above $30 million unless the Wohlstadter family provided the additional amount. After consideration, Mr. Samuel Wohlstadter indicated that at the JVOC's request and as an accommodation to facilitate completion of the Newco transaction, he was willing to invest indirectly in MSD by financing any BioVeris capital contribution exceeding $30 million. His agreement to do so was finalized on July 23, 2003. 53 Also on July 21, 2003, the IGEN board of directors held a special meeting and discussed the current status of the possible Newco transaction. Representatives of Cravath discussed the fiduciary duties of the IGEN board of directors in connection with the consideration of the proposed transaction and various counsel to IGEN discussed the status of pending litigation. Members of management reviewed for the IGEN board of directors the structure of the transaction and the BioVeris business plan. The IGEN board of directors then discussed the relationship between IGEN and MSD, including that the JVOC and MSD had not yet been able to reach an agreement for MSD's and MST's consent to a transaction between IGEN and Roche and discussed a number of alternatives, including the purchase by Mr. Samuel Wohlstadter of shares of BioVeris preferred stock that economically mirror the class C interests in MSD to be held by BioVeris, the proceeds of which would be used to fund a portion of the final capital contribution to MSD. Representatives of Lehman Brothers then made a detailed financial presentation regarding the Newco transaction and rendered an oral opinion, which was subsequently confirmed in writing on July 24, 2003 that, based upon and subject to the matters to be contained in the written opinion, as of the date of meeting, from a financial point of view, the consideration to be received by the stockholders of IGEN in the proposed transaction is fair to such stockholders and Lehman Brothers would be prepared to issue an opinion in writing to that effect, assuming satisfactory resolution of the remaining outstanding issues. Representatives of Cravath presented to the IGEN board of directors a summary of the principal terms of the draft merger agreement and related transaction agreements. Members of management presented to the IGEN board of directors a summary of the principal terms of the ongoing commercial agreements. On July 22, 2003, in response to a press report, IGEN issued a press release confirming that it was in discussions with Roche with respect to a potential transaction. On July 22, 23 and 24, 2003, representatives of IGEN and Roche and their respective legal advisors continued to exchange drafts of the various related transaction agreements and ongoing commercial agreements and have telephone conferences to finalize these agreements. On these dates, Mr. Samuel Wohlstadter, representatives of IGEN and Roche and their respective legal advisors also negotiated a release and agreement with respect to certain companies that are affiliated with Mr. Samuel Wohlstadter. On July 23, 2003, Roche filed a petition with the Appellate Court for a re-hearing of a portion that court's decision in the Roche litigation. Also on July 23, 2003, after Mr. Jacob Wohlstadter agreed to withdraw his request that changes be made to the MSD joint venture agreement and other related agreements and the BioVeris preferred stock purchase agreement with Mr. Samuel Wohlstadter regarding the BioVeris preferred stock was finalized, a representative of the JVOC and Mr. Jacob Wohlstadter and their respective legal advisors sought to finalize the MSD consent and MSD letter agreement. In addition, on July 23, 2003, in-house counsel to IGEN and Cravath were asked by the JVOC to review the near-final versions of the MSD letter agreement and MSD consent. On the evening of July 23, 2003, the JVOC and Mr. Jacob Wohlstadter agreed that BioVeris would provide additional funding to MSD of $37.5 million following completion of the proposed transaction with Roche. In addition, the parties agreed that the MSD joint venture agreement would expire upon the first to occur of the completion of the merger or the termination of the merger agreement. Mr. Jacob Wohlstadter and the JVOC agreed that the issues relating to expenses would not be addressed in the letter agreement, without prejudice to either party's position concerning IGEN's existing obligation to pay such expenses. On July 24, 2003, the JVOC and its counsel met at 10:00 a.m. and considered the agreements with MSD, MST and Mr. Jacob Wohlstadter, pursuant to which, among other things, MSD and MST would grant their consent to the proposed transaction between IGEN and Roche, BioVeris would agree to provide a final capital contribution of $37.5 million (of which any amount in excess of $30.0 million would be funded by Mr. Samuel Wohlstadter through the purchase of shares of BioVeris preferred stock that economically mirror the class C interests in MSD to be held by BioVeris) to MSD and the MSD joint venture agreement would expire upon the first to occur of the completion of the merger or the termination 54 of the merger agreement. The JVOC resolved to recommend the agreements with MSD, MST and Mr. Jacob Wohlstadter to the IGEN board of directors. Also on July 24, 2003, the IGEN board of directors held a special meeting at 11:00 a.m. to consider and approve the proposed transaction, whereby Roche would acquire IGEN and simultaneously IGEN would distribute to its stockholders shares of a new public company holding certain of IGEN's assets and liabilities. Representatives of Cravath reviewed the purpose of the meeting and explained the agenda for the meeting. Representatives of Potter Anderson then summarized the results of the negotiations among the JVOC, MSD and MST in connection with obtaining the consents of MSD and MST to the proposed transaction and the principal terms of the MSD letter agreement. After discussion, the members of the JVOC unanimously recommended to the IGEN board of directors that they approve the agreements with MSD, MST and Mr. Jacob Wohlstadter. Management then summarized the developments relating to the ongoing litigation agreement and the ongoing commercial agreements. Representatives of Cravath then provided an update concerning the remaining agreements in connection with the proposed transaction and summarized the principal terms of the release and agreement, the MSD consent, the MSD letter agreement and the purchase agreement between BioVeris and Mr. Samuel Wohlstadter regarding the BioVeris preferred stock. Representatives of Lehman Brothers advised the IGEN board of directors that they had reviewed the developments in the transaction and rendered an oral opinion, which was subsequently confirmed in writing that, based upon and subject to the matters contained in the written opinion, as of that date, from a financial point of view, the consideration to be received by the stockholders of IGEN in the proposed transaction is fair to such stockholders. After discussion and consideration, the IGEN board of directors unanimously voted to approve the merger and related transactions, declared the merger agreement to be advisable and resolved to recommend that IGEN stockholders vote in favor of the adoption of the merger agreement. Following the board meeting, representatives of IGEN, Roche and MSD and their respective advisors met at Cravath's offices to finalize, execute and deliver the merger and related transaction agreements and ongoing commercial agreements. At 4:21 p.m. on July 24, 2003, immediately following the execution and delivery of the merger agreement and related transaction agreements and ongoing commercial agreements, IGEN and Roche issued a joint press release announcing the proposed transaction between IGEN and Roche. REASONS FOR THE MERGER AND RELATED TRANSACTIONS REASONS FOR THE TRANSACTION. In reaching its determination to approve the merger agreement and the related transaction agreements, the merger and related transactions, and to unanimously recommend that IGEN stockholders adopt the merger agreement, the IGEN board of directors consulted with its management team, financial advisors, legal counsel and other advisors and considered the short-term and long-term interests of IGEN and its stockholders. In particular, the IGEN board of directors considered the following factors, all of which it deemed favorable, in reaching its determination to approve the merger agreement and the related transaction agreements and the merger and related transactions: - the IGEN board of directors' view that the merger maximizes the value to IGEN stockholders of the right to terminate IGEN's license to Roche Diagnostics gained in the Roche litigation and is thus in the best interests of IGEN and its stockholders; - the IGEN board of directors' conclusion that Roche would provide more value for the rights it had lost as a result of the Roche litigation than any other party; - the cash portion of the merger consideration represents a substantial premium to the historical price of IGEN's common stock; - the total expected transaction value to IGEN stockholders represents a significant premium to the historical price of IGEN's common stock; 55 - the opportunity for IGEN stockholders to benefit from BioVeris's potential growth through their continued ownership of BioVeris; - the presentations of Lehman Brothers to the IGEN board of directors, and the opinion of Lehman Brothers that, based upon and subject to the matters described in the opinion, as of the date of the opinion, from a financial point of view, the consideration to be received by IGEN stockholders in the merger was fair to such stockholders; - the IGEN board of directors' view that the merger will enable IGEN to maximize the value of its technology, assets and businesses; - following the merger and the final contribution to MSD, BioVeris would be free from debt (other than trade payables) and have approximately $125 million in cash; - BioVeris will own IGEN's intellectual property rights, including those related to ECL technology, and obtain the rights to certain improvements relating to Roche's Elecsys product line including the right to commercialize that technology directly and through third-party collaborators, subject to the terms of the improvements license agreement; - the opportunity for BioVeris to create additional value through its assumption of IGEN's biodefense, life science and industrial product lines as well as IGEN's opportunities in the clinical diagnostics and healthcare fields, and through the commercialization of IGEN's intellectual property, including ECL technology; - the opportunity for BioVeris to create additional value through the establishment of new strategic partnerships; - the terms and conditions of the merger agreement and the related transaction agreements, including the provisions that permit IGEN to continue to receive unsolicited inquiries and proposals regarding other potential business combinations, negotiate and provide information to third parties making such inquiries or proposals, and, subject to the satisfaction of certain conditions, in the exercise of its fiduciary duties, withdraw or modify its recommendation to IGEN stockholders regarding the merger, or terminate the merger agreement, and enter into a more favorable transaction with a third party, subject to the payment of a $26.6 million termination fee to Roche; and - the IGEN board of directors' belief that the conditions to the completion of the merger are limited and likely to be satisfied. The IGEN board of directors also considered a number of potentially negative factors in its deliberations concerning the merger agreement and the related transaction agreements, including: - the risk that the benefits sought to be achieved in the merger and related transactions will not be achieved, including that BioVeris is not successful in achieving growth or developing its business; - the fact that it was and is difficult to estimate what the value of the shares of BioVeris common stock will be at the time they are distributed to IGEN stockholders; - the risk that an active public trading market for BioVeris common stock does not currently exist and may not develop after the completion of the merger; - the obligation of BioVeris to make to MSD a class C capital contribution in the amount of $37.5 million (of which any amount in excess of $30 million will be funded by Mr. Samuel Wohlstadter through the purchase of shares of BioVeris preferred stock that economically mirror the class C interests in MSD to be held by BioVeris); - the obligation of BioVeris to pay up to $20 million to IGEN to the extent the average of the high and the low market capitalization for BioVeris on the first day of trading of BioVeris's common stock after the completion of the merger exceeds a certain threshold; and 56 - the risks to IGEN's business that might result from constraints imposed by interim operating covenants contained in the merger agreement. The IGEN board of directors also considered the financial viability of BioVeris as an independent company. Set forth below are the material factors considered by the IGEN board of directors in analyzing the restructuring: - the financial condition, results of operations, business and prospects of BioVeris as an independent company, including the expected $125 million of initial cash; - management's business plan for BioVeris; - the fact that BioVeris would have a different and smaller revenue base, including substantially less royalty revenue, than IGEN and significant operating losses; - the current biodefense, life science, industrial and clinical diagnostics industries and market conditions in the global clinical diagnostics market; and - the indemnification obligations of BioVeris to Roche and IGEN following the completion of the merger. The IGEN board of directors was aware of the potential benefits of the merger and related transactions to the members of IGEN's management and the IGEN board of directors, discussed below in "-- Interests of IGEN's Directors and Executive Officers in the Merger and Related Transactions." The IGEN board of directors determined that these potential benefits were such that they would not affect the ability of the members of the IGEN board of directors to discharge their duties. In view of the wide variety of factors considered by the IGEN board of directors, the IGEN board of directors did not find it practicable to, and did not, quantify or otherwise attempt to assign relative weights to the specific factors considered. The IGEN board of directors viewed its position and recommendation as being based on the totality of the information presented to and considered by it. After taking into consideration all of the factors set forth above, the IGEN board of directors determined that the potential benefits of the proposed merger and related transactions far outweighed the potential detriments associated with the proposed merger and related transactions. RECOMMENDATION OF THE IGEN BOARD OF DIRECTORS The IGEN board of directors has carefully reviewed and considered the terms and conditions of the proposed merger and related transactions, has unanimously approved the merger agreement and the related transaction agreements, and has unanimously determined that the merger agreement is advisable and in the best interests of IGEN and its stockholders. Accordingly, the IGEN board of directors unanimously recommends that IGEN stockholders vote "FOR" the adoption of the merger agreement. IGEN stockholders are not being asked to vote on the restructuring. OPINION OF LEHMAN BROTHERS On July 24, 2003, Lehman Brothers rendered its opinion to the IGEN board of directors that as of such date, and based upon and subject to certain matters stated therein, from a financial point of view, the consideration to be received by the IGEN stockholders in the merger is fair to the IGEN stockholders. THE FULL TEXT OF LEHMAN BROTHERS' WRITTEN OPINION, DATED JULY 24, 2003, WHICH IS REFERRED TO AS THE LEHMAN BROTHERS OPINION, IS ATTACHED AS ANNEX 15 TO THIS PROXY STATEMENT/PROSPECTUS. STOCKHOLDERS MAY READ SUCH OPINION FOR A DISCUSSION OF THE ASSUMPTIONS MADE, PROCEDURES FOLLOWED, FACTORS CONSIDERED AND LIMITATIONS UPON THE REVIEW UNDERTAKEN BY LEHMAN BROTHERS IN RENDERING ITS OPINION. THE FOLLOWING IS A SUMMARY OF THE LEHMAN BROTHERS OPINION AND THE METHODOLOGY THAT LEHMAN BROTHERS USED TO RENDER ITS FAIRNESS OPINION. Lehman Brothers' advisory services and opinion were provided for the information and assistance of the IGEN board of directors in connection with its consideration of the merger. The Lehman Brothers 57 opinion is not intended to be and does not constitute a recommendation to any IGEN stockholder as to how such stockholder should vote on the merger. Lehman Brothers was not requested to opine as to, and the Lehman Brothers opinion does not address, IGEN's underlying business decision to proceed with or effect the merger. In arriving at its opinion, Lehman Brothers reviewed and analyzed: - the merger agreement and the specific terms of the merger and related transactions; - publicly available information concerning IGEN and Roche that Lehman Brothers believed to be relevant to its analysis; - financial and operating information with respect to the business, operations and prospects of IGEN and BioVeris furnished to Lehman Brothers by IGEN, including, without limitation, certain projections of future financial performance of IGEN and BioVeris prepared by the management of IGEN; - a trading history of IGEN common stock from its initial public offering on February 3, 1994 to July 24, 2003; - a comparison of the historical financial results and present financial condition of IGEN with those of other companies that Lehman Brothers deemed relevant; and - a comparison of the financial terms of the proposed merger and related transactions with the financial terms of certain other transactions that Lehman Brothers deemed relevant. In addition, Lehman Brothers had discussions with IGEN management concerning IGEN's businesses, operations, assets, financial condition and prospects and undertook such other studies, analyses and investigations as Lehman Brothers deemed appropriate. In arriving at its opinion, Lehman Brothers assumed and relied upon the accuracy and completeness of the financial and other information used by Lehman Brothers without assuming any responsibility for independent verification of such information. Lehman Brothers further relied upon the assurances of IGEN management that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of IGEN and BioVeris, upon advice of IGEN, Lehman Brothers assumed that such projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of IGEN management as to IGEN's and BioVeris's future financial performance and that IGEN and BioVeris would perform substantially in accordance with such projections. Lehman Brothers was not authorized to solicit and did not solicit any indications of interest from any third party with respect to the purchase of all or a part of IGEN's business. In arriving at its opinion, Lehman Brothers did not conduct a physical inspection of IGEN's properties and facilities and did not make or obtain any evaluations or appraisals of the assets or liabilities of IGEN. The Lehman Brothers opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, the date of such opinion. In connection with rendering its opinion, Lehman Brothers performed certain financial and other analyses as described below. In arriving at its opinion, Lehman Brothers did not ascribe a specific range of value to IGEN, but rather made its determination as to the fairness, from a financial point of view, to IGEN stockholders of the consideration to be paid by Roche in the merger on the basis of financial analyses. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial and comparative analysis and the application of those methods to the particular circumstances, and, therefore, such an opinion is not readily susceptible to summary description. Furthermore, in arriving at its opinion, Lehman Brothers did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Lehman Brothers believes that its analyses must be considered as a whole and that considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion. In its analyses, Lehman Brothers made numerous assumptions with respect to industry 58 performance, general business and economic conditions and other matters, many of which are beyond the control of IGEN. These assumptions may not be realized and actual results may differ materially from historical results or from the anticipated results used by Lehman Brothers in performing its analysis. Any estimates contained in these analyses were not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth therein. In addition, analyses relating to the value of businesses do not purport to be appraisals or to reflect the prices at which businesses actually may be sold. The following is a summary of the material financial analyses used by Lehman Brothers in connection with providing its opinion to the IGEN board of directors. Considering any portion of such analyses and the factors considered, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying the Lehman Brothers opinion. EVALUATION OF IGEN Lehman Brothers evaluated each of the following sources of value to IGEN stockholders: Roche Royalties Under the 1992 License Agreement. Lehman Brothers estimated the value of the royalty stream from Roche under the 1992 license agreement based on a discounted cash flow analysis using financial projections prepared by IGEN management. In such analysis, Lehman Brothers applied the then existing royalty rates being paid by Roche to an estimate of the revenues projected to be generated by Roche through the use of the IGEN technology licensed under the 1992 license agreement. The stream of after-tax cash flows resulting from this calculation was discounted to the present using rates of between 10% and 12%. Based on this analysis, Lehman Brothers calculated a present value of the license giving rise to the pre-existing royalty stream of approximately $410 to $475 million. Lehman Brothers believed that the right to terminate this license, a right upheld by the Appellate Court in July 2003, gave IGEN an opportunity to improve on the value of the royalty stream discussed above, but was not able to place any precise estimate on the magnitude of such potential improvement. Point-of-Care Business Taken Over From Roche and Assay Development Business. Lehman Brothers estimated the value of the point-of-care business taken over from Roche and the related assay development business based on a discounted cash flow analysis using financial projections prepared by IGEN management. The point-of-care business was taken over from Roche pursuant to a July 1998 court ruling and was limited to the existing installed base. The stream of cash flows resulting from the point-of-care and assay development businesses were discounted to the present using rates of between 10% and 12%. Based on this analysis, Lehman Brothers calculated a present value of the point-of-care and assay development businesses of approximately $1.9 to $2.0 million. Other IGEN Businesses. Lehman Brothers estimated the value of the other IGEN businesses based on a discounted cash flow analysis using financial projections prepared by IGEN management. These businesses included IGEN's life science, biodefense, industrial and point-of-care diagnostics businesses and other royalty and contract fees. These businesses represented approximately $17.8 million of IGEN's revenues in fiscal 2003. While the projections indicated a very significant increase in the revenues of these businesses, Lehman Brothers recognized that these businesses were in a fairly early stage of development and would require significant investment over the next several years. As a result of the risk associated with these activities and the investment and time required to reach break-even, the stream of cash flows resulting from these activities were discounted using rates of between 30% and 40%. Lehman Brothers estimated a value for these businesses at the end of the projection period based on a range of multiples of estimated EBITDA of between 9.0x and 11.0x. Due to the limited visibility in the financial forecasts beyond the early years, Lehman Brothers examined the results of the analysis over both a five-year period ending March 31, 2008 and a seven-year period ending March 31, 2010. Based on the discount rates and terminal value multiples outlined above, Lehman Brothers calculated a present value of the cash flows and terminal value from the other IGEN businesses of approximately $36.1 to $99.7 million using the projections for the five years ended March 31, 59 2008. If the analysis were extended to March 31, 2010, the resulting present value of the cash flows and terminal value from the other IGEN businesses would be approximately $102.0 to $251.4 million. Lehman Brothers believed it was appropriate to focus more closely on the five-year analysis and concluded that the present value of the cash flows and terminal value from the other IGEN businesses would be in the range of $70 to $100 million. At the mid-point of this range, Lehman Brothers noted that the value reflected a multiple of 4.8x fiscal 2003 revenues and 2.2x fiscal 2004 projected revenues. While the analysis of the other IGEN businesses included the cash cost of providing IGEN's 2003 funding commitment to MSD, Lehman Brothers did not attempt to independently value IGEN's interest in MSD nor did they value IGEN's interests in Wellstat Therapeutics Corporation, or Wellstat Therapeutics, and Proteinix Corporation, or Proteinix. Lehman Brothers viewed these interests as investments in privately held and early stage development companies that had an uncertain future value. Lehman Brothers noted that the transaction provided for IGEN stockholders to receive the full value of the other IGEN businesses and the interests in MSD, Wellstat Therapeutics and Proteinix through the distribution of shares of BioVeris common stock to IGEN stockholders. Net Financial Assets in IGEN. In addition to the operating assets, Lehman Brothers evaluated the net financial assets of IGEN. On July 9, 2003, the Appellate Court upheld $18.6 million in monetary damages related to the litigation between IGEN and Roche. Lehman Brothers assumed that the taxable gain from the judgment proceeds would be fully offset by IGEN's existing net operating losses. As of March 31, 2003, IGEN had available for income tax reporting purposes net operating loss and general business credit carryforwards approximating $206.3 million and $7.3 million, respectively. The judgment proceeds of $18.6 million would therefore be fully offset by these carryforwards. As of June 30, 2003, IGEN had $22.3 million of cash, $16.7 million of third party debt and $32.3 million face amount of convertible debentures (convertible into IGEN common stock at a price of $31.00 per share), approximately 1.551 million options with an average exercise price of $18.29 per share and approximately 282,000 warrants with an exercise price of $31.00 per share. For purposes of its analysis, and because the IGEN stock price was in excess of $31.00 per share, Lehman Brothers assumed that the convertible debentures were converted and all outstanding options and warrants were exercised. The proceeds from the exercise of options and warrants would be approximately $37.1 million. The combination of the proceeds from the judgment, the proceeds from the exercise of options and warrants and the cash, less the third party debt, resulted in a net cash position of $60.9 million. In light of the investment required to fund IGEN's ongoing operations and that the net financial assets would be required to fund the investment, Lehman Brothers believed that the value of the net financial assets should be discounted by approximately 25% when considered in the context of IGEN's overall valuation. Based on this analysis, Lehman Brothers ascribed a value of $46.2 million to the net financial assets of IGEN. Combining the valuations outlined above, Lehman Brothers noted that IGEN would have a value of between $528.1 and $623.1 million before giving effect to the value associated with the option to terminate the license to Roche or the interests in MSD, Wellstat Therapeutics or Proteinix. Lehman Brothers further noted that this value represented approximately $19.75 to $23.31 per share. EVALUATION OF THE CONSIDERATION In the merger, IGEN stockholders will receive a cash payment from Roche and one share of BioVeris common stock for each share of IGEN common stock held by such stockholder. Lehman Brothers evaluated the following sources of value to IGEN stockholders: Cash Consideration. IGEN stockholders will receive $47.25 per share for each share of IGEN common stock outstanding. Lehman Brothers noted that the cash consideration alone represented a 27.0% premium to the closing price of IGEN common stock on July 24, 2003 (the date of the announcement of the merger), a 39.4% premium to the closing price of IGEN common stock on July 18, 2003, a 39.4% premium to the 60-day average closing price of IGEN common stock as of July 24, 2003 and a 1.3% premium to its all-time high. 60 BioVeris. Lehman Brothers estimated the value of BioVeris based on a discounted cash flow analysis using financial projections prepared by IGEN management. BioVeris will include IGEN's life science, biodefense, industrial testing and point-of-care diagnostics businesses and other royalty and contract fees, as well as the newly acquired licenses to PCR technology. BioVeris will also own IGEN's current interest in MSD, Wellstat Therapeutics and Proteinix. As discussed above, these businesses represented approximately $17.8 million of IGEN's revenues in fiscal 2003. While the projections indicated a very significant increase in the revenues of these businesses, Lehman Brothers recognized that these businesses were in a fairly early stage of development and would require significant investment over the next several years. In addition, in light of the non-exclusive nature of the license granted to the license sub post-merger, BioVeris may grant licenses to other parties to use its technology in the diagnostics field. As a result of the risk associated with these activities and the investment and time required to reach break-even, BioVeris's projected cash flows were discounted using rates of between 30% and 40%. Lehman Brothers estimated a value of BioVeris at the end of the projection period based on a range of multiples of estimated EBITDA of between 9.0x and 11.0x. Due to the limited visibility in the financial forecasts of BioVeris beyond the early years, Lehman Brothers examined the results of the analysis over both a five-year period ending March 31, 2008 and a seven-year period ending March 31, 2010. Based on the discount rates and terminal value multiples outlined above, Lehman Brothers calculated a present value of the cash flows and terminal value of BioVeris to be approximately $50.0 to $133.4 million using the projections for the five years ended March 31, 2008. If the analysis were extended to March 31, 2010, the resulting present value of the cash flows and terminal value for BioVeris would be approximately $103.7 to $270.7 million. Lehman Brothers believed it was appropriate to focus more closely on the five-year analysis and concluded that the present value of the cash flows and terminal value of BioVeris would be in the range of $95 to $125 million. At the mid-point of this range, Lehman Brothers noted that the value reflected a multiple of 6.2x BioVeris's fiscal 2003 revenues and 2.5x BioVeris's fiscal 2004 projected revenues. While the analysis of BioVeris included the cash cost of providing IGEN's 2003 MSD funding commitment and the $37.5 million final capital contribution to MSD by BioVeris following completion of the merger, Lehman Brothers did not attempt to independently value IGEN's interest in MSD nor did they value IGEN's interests in Wellstat Therapeutics and Proteinix. Cash Balance in BioVeris. In addition to the operating assets, Lehman Brothers evaluated the cash balance in BioVeris. At or before the completion of the merger, IGEN will contribute all of its available cash, after the payment of fees and expenses associated with the merger, to BioVeris. Based on the balances at June 30, 2003, Lehman Brothers estimated the aggregate cash contribution to be approximately $213.4 million. Upon the completion of the merger, BioVeris will acquire a PCR product license from Roche for a cash payment of $50 million, reducing the net cash balance at BioVeris to approximately $163.4 million. In light of the investment required to fund BioVeris's ongoing operations and that the cash would be required to fund the investment, Lehman Brothers believed that the value of the cash should be discounted by approximately 25% when considered in the context of BioVeris's overall valuation. Based on this analysis, Lehman Brothers ascribed a value of $122.6 million to the cash balance of BioVeris. Combining the value Lehman Brothers ascribed to the cash balances at BioVeris and the present value of the cash flows and terminal value discussed above, Lehman Brothers arrived at an estimated trading value of BioVeris of approximately $217.6 to $247.6 million. Lehman Brothers noted that BioVeris would have a small revenue base and significant operating losses as it invested in the development of its businesses. In light of the limited equity research coverage of IGEN pre-merger, Lehman Brothers noted that the initial trading value of BioVeris could be less than the aggregate value suggested above. Assuming a distribution of one share of BioVeris common stock for each share of IGEN common stock, the analysis above suggests a per share value of BioVeris common stock of between $8.14 and $9.26 per share, and an aggregate value of the merger, including both the $47.25 per share of cash and the suggested per share value of BioVeris common stock, of between $55.39 and $56.51 per share. Lehman Brothers noted that at the mid-point, the aggregate value of the merger represented a premium of 50.4% 61 to the closing stock price of IGEN common stock on July 24, 2003 (the date of the announcement of the merger), a 65.1% premium to the closing stock price of IGEN common stock on July 18, 2003, a 65.0% premium to the 60-day average closing price of IGEN common stock as of July 24, 2003 and a 20.0% premium to its all-time high. Lehman Brothers is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. The IGEN board of directors selected Lehman Brothers because of its expertise, reputation and familiarity with IGEN and the biotechnology and pharmaceutical industries generally and because its investment banking professionals have substantial experience in transactions comparable to the merger. As compensation for its services in connection with the merger, IGEN has agreed to pay Lehman Brothers a fee equal to 1.2% of the consideration paid in the merger, which is approximately $16.7 million, of which IGEN paid to Lehman Brothers $250,000 in May 2001 and $750,000 in July 2002 in connection with a Lehman Brothers opinion issued in April 2001, and the remainder of which will be paid upon completion of the merger. In addition, IGEN has agreed to reimburse Lehman Brothers upon completion of the merger for reasonable out-of-pocket expenses incurred in connection with the merger and to indemnify Lehman Brothers for certain liabilities that may arise out of its engagement by IGEN and the rendering of the Lehman Brothers opinion. In the ordinary course of its business, Lehman Brothers may actively trade in the debt or equity securities of IGEN and Roche for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities. In addition, LBI Group Inc. an affiliate of Lehman Brothers, held approximately $10 million in principal amount of outstanding convertible debt of IGEN, which was converted into approximately 322,580 shares of IGEN common stock on September 22, 2003. INTERESTS OF IGEN'S DIRECTORS AND EXECUTIVE OFFICERS IN THE MERGER AND RELATED TRANSACTIONS In considering the recommendation of the IGEN board of directors that IGEN stockholders vote "FOR" the adoption of the merger agreement, IGEN stockholders should be aware that the members of the IGEN board of directors and IGEN's executive officers have personal interests in the merger and related transactions that are or may be different from, or in addition to, the interests of other IGEN stockholders. These interests are summarized below. The IGEN board of directors was aware of, and considered, the interests of the IGEN directors and executive officers in approving the merger agreement and the related transaction agreements. ACCELERATED VESTING Upon completion of the merger, all outstanding options granted under IGEN's stock option plans, including unvested options, will be canceled and the holder of any such options will have the right to receive for each share covered by such option: - cash from Roche equal to the excess of $47.25 over the exercise price of such option (without interest); and - one share of BioVeris common stock. 62 Upon completion of the merger, the vesting of such unvested options held by the members of the IGEN board of directors and IGEN's executive officers will, therefore, in effect, accelerate. BioVeris expects that as of December 31, 2003, the value of option rights held by IGEN's directors and executive officers that will be accelerated will be as follows: NAME VALUE OF ACCELERATED OPTIONS ---- ---------------------------- Samuel J. Wohlstadter.................. $2,975,700 plus 175,000 shares of BioVeris common stock Richard J. Massey, Ph.D. .............. $1,271,203 plus 68,133 shares of BioVeris common stock George V. Migausky..................... $510,895 plus 36,750 shares of BioVeris common stock Richard W. Cass........................ $214,430 plus 8,000 shares of BioVeris common stock Anthony R. Rees........................ $214,430 plus 8,000 shares of BioVeris common stock Robert R. Salsmans..................... $119,750 plus 5,000 shares of BioVeris common stock Joop Sistermans........................ $153,590 plus 6,500 shares of BioVeris common stock INDEMNIFICATION AND INSURANCE The post-closing covenants agreement provides that Roche will, to the fullest extent permitted by law, cause IGEN to honor all of its existing obligations to indemnify the current or former directors or officers of IGEN, whether pursuant to IGEN's certificate of incorporation or by-laws or individual indemnity agreements, for acts or omissions occurring prior to completion of the merger. The post-closing covenants agreement also provides that Roche shall not permit IGEN to amend or repeal any provision of its certificate of incorporation or by-laws if such action would adversely affect the rights of individuals who on or prior to the completion of the merger were entitled to advances, indemnification or exculpation thereunder for actions or omissions prior to the completion of the merger. The post-closing covenants agreement also provides that for six years after the completion of the merger, Roche will cause to be maintained in effect the current policies of directors' and officers' liability insurance with policy limits of $30 million maintained by IGEN for claims arising from or related to facts or events which occurred at or prior to the completion of the merger. Roche's obligation to provide this insurance coverage is subject to a cap of 250% of the amount per annum required to be paid by IGEN in the twelve months ending December 12, 2003. However, if the annual premiums for such insurance exceed such amount, Roche shall nevertheless obtain such insurance and BioVeris will pay the excess over 250% of the amount per annum required to be paid by IGEN in the twelve months ending December 12, 2003. IGEN has been advised by its directors' and officers' liability insurer that the total cost for such insurance would be approximately 200% of the amount per annum required to be paid by IGEN in the twelve months ending December 12, 2003. CONTINUATION OF EXECUTIVE OFFICERS AND DIRECTORS IGEN's three executive officers are expected to continue in similar positions with BioVeris and their annual salary is anticipated to be initially comparable to the current salaries being received from IGEN, which is approximately $1,011,000 in the aggregate. For a more complete description of BioVeris's executive officers and the compensation of BioVeris's executive officers, see "Management." IGEN's directors, other than Mr. Richard Cass, are expected to continue as directors of BioVeris. Non-employee directors of BioVeris are expected to receive increased compensation from the compensation they received at IGEN. For a more complete description of BioVeris's directors and the compensation of BioVeris's directors, see "Management -- Compensation of Directors" and "Management -- Executive Compensation." 63 TRANSACTION BONUS PAYMENTS Simultaneous with completion of the merger and related transactions, the following executive officers of IGEN will be entitled to receive transaction bonus payments in the amounts set forth below: NAME TRANSACTION BONUS ---- ----------------- Samuel J. Wohlstadter....................................... $1,278,000 Richard J. Massey, Ph.D..................................... 450,000 George V. Migausky.......................................... 450,000 Each transaction bonus payment is contingent upon the individual executive officer providing a release of the respective obligations of IGEN and BioVeris under IGEN's termination protection program. STOCK OPTIONS If approved by the IGEN stockholders, BioVeris will adopt the BioVeris 2003 stock incentive plan pursuant to which BioVeris executive officers and directors will be eligible to receive option grants and other equity-based awards. The proposed BioVeris 2003 stock incentive plan provides that on the day following each annual meeting of BioVeris stockholders, each non-employee director shall receive an automatic grant of options to purchase 4,000 shares of BioVeris common stock. In addition, any person who is appointed or elected as a non-employee director at any other time shall automatically be granted an option to purchase 4,000 shares of BioVeris common stock on the date of such appointment or election. Each grant will have an exercise price equal to fair market value on the date of grant and will vest in full on the first anniversary of the grant date. MSD AND THE MSD AGREEMENTS As part of the restructuring, IGEN will transfer its equity interest in MSD to BioVeris and will assign the MSD agreements to BioVeris. BioVeris has agreed, under the MSD letter agreement, to make a final capital contribution of $37.5 million to MSD on the first business day following the completion of the merger. Of the $37.5 million, any amount in excess of $30 million (including any interim funding provided by IGEN as described in the next sentence) will be funded by Mr. Samuel Wohlstadter through the purchase of shares of BioVeris series B preferred stock that economically mirror the class C interest in MSD to be held by BioVeris, as specified in the BioVeris preferred stock purchase agreement. In the event the completion of the merger has not occurred prior to December 1, 2003, IGEN has agreed under the MSD letter agreement to provide continued interim funding at approximately $1.7 million per month until the earlier to occur of the completion of the merger or termination of the merger agreement. The monthly interim funding is one-twelfth of IGEN's aggregate funding commitment under the 2003 MSD budget approved by the JVOC. After the restructuring, Dr. Richard Massey, IGEN's and BioVeris's president and chief operating officer, will be BioVeris's representative on the MSD board of managers and will also serve as the treasurer and secretary of MSD. Dr. Massey will receive no compensation from MSD or BioVeris for serving as the treasurer and secretary of MSD. Neither Dr. Massey nor any other executive officer or director of IGEN or BioVeris has any ownership interest in MST or MSD, other than through ownership of interests in IGEN or BioVeris and other than the BioVeris series B preferred stock to be purchased by Mr. Samuel Wohlstadter if and only to the extent that BioVeris's final capital contribution (including any interim funding provided by IGEN as described above) exceeds $30 million. Mr. Samuel Wohlstadter and Mrs. Nadine Wohlstadter disclaim any ownership interest in MST or MSD as a result of Mr. Jacob Wohlstadter's direct or indirect ownership interest in those entities. BioVeris has agreed to assume IGEN's obligations under a letter agreement dated August 15, 2001, between the indemnified parties and IGEN. Pursuant to the letter agreement, IGEN agreed to fund the reasonable ongoing legal fees and related charges and costs incurred by the indemnified parties arising out of or related to the Roche litigation, including any legal fees and related charges and costs arising out of or related to any of IGEN's ongoing negotiations regarding, and the settlement of, the Roche litigation. MSD has submitted to IGEN invoices for legal fees and expenses for the period from March 1, 2003 through 64 September 30, 2003 in the amount of approximately $1.3 million that it asserts were reasonably incurred in connection with the indemnified parties' participation and involvement in IGEN's ongoing negotiations and settlement of the Roche litigation and their review of the documents relating to the merger and related transactions. The indemnified parties have claimed that IGEN must reimburse these fees and expenses pursuant to the letter agreement. The JVOC, through its counsel, has reviewed the relevant invoices, and has approved the payment to MSD of, and IGEN has paid, approximately $423,000 of the submitted expenses, which the JVOC believes is the amount IGEN is obligated to pay under the terms of the letter agreement for the period from March 1, 2003 through September 30, 2003. The indemnified parties, through their counsel, have not accepted the JVOC's determination, and the JVOC believes it is likely that the indemnified parties will continue to seek reimbursement for the balance of the $1.3 million claimed which approximates $877,000. In addition, MSD submitted to IGEN invoices for legal fees and expenses of approximately $26,000 for October 2003 and approximately $21,000 for November 2003, which the indemnified parties have also claimed that IGEN must reimburse pursuant to the letter agreement. The JVOC has not yet made any determination regarding MSD's claims for October 2003 and November 2003. The JVOC expects that the indemnified parties will submit claims for reimbursement of additional expenses for the period from December 1, 2003 through the completion of the merger. As part of the restructuring, BioVeris will assume IGEN's obligations under the following agreements: - an employment agreement among MSD, IGEN, MST and Mr. Jacob Wohlstadter, pursuant to which Mr. Jacob Wohlstadter will be entitled to receive from MSD an annual salary of $250,000, subject to annual adjustment, an annual cash bonus in an amount not to exceed 20% of his annual salary and other pension, welfare and fringe benefits; - a consulting agreement between IGEN and Mr. Jacob Wohlstadter, pursuant to which Mr. Jacob Wohlstadter will be entitled to receive from BioVeris such fees as BioVeris and Mr. Jacob Wohlstadter agree to when consulting services, if any, that may be provided to and at the request of BioVeris; and - an indemnification agreement between IGEN, Mr. Jacob Wohlstadter and JW Consulting Services, L.L.C., a company established and wholly-owned by Mr. Jacob Wohlstadter, pursuant to which BioVeris will indemnify Mr. Jacob Wohlstadter and JW Consulting Services, L.L.C. against any claims arising out of the performance or non-performance of services to or for the benefit of BioVeris. Also, upon completion of the merger, the MSD joint venture agreement will expire and MSD will have the right to purchase BioVeris's entire interest in MSD for a purchase price equal to fair market value determined in accordance with the MSD joint venture agreement, less a discount factor. The discount factor will be equal to 7.5% if the MSD joint venture agreement expires upon the completion of the merger and has not been otherwise terminated before completion. In the event MSD or MST elects to purchase BioVeris's interest in MSD, BioVeris will only be entitled to receive the purchase price payable over time in installments equal to the sum of 5% of MSD net sales, as determined in accordance with the MSD agreements, and 20% of the net proceeds realized from certain third-party financings in accordance with the MSD agreements. In the event such future net sales of MSD or third-party financings do not materialize, BioVeris will not receive any payments from MSD or MST, as the case may be, for the purchase of BioVeris's interest in MSD. For a more complete description of the employment agreement, the consulting agreement and the indemnification agreement, see "Certain Relationships and Related Party Transactions -- MSD and the MSD Agreements." RELEASE AND AGREEMENT Simultaneously with the execution and delivery of the merger agreement, Hyperion Catalysis International, Wellstat Biologics Corporation, Wellstat Therapeutics, Proteinix and Integrated Chemical Synthesizers, Inc., which are referred to in this proxy statement/prospectus as the related companies, 65 entered into the release and agreement with BioVeris and IGEN, pursuant to which, among other things, IGEN, on the one hand, and the related companies, on the other hand, agreed to release each other from any liabilities or obligations arising out of their relationship or any of their agreements and understandings, which are referred to in this proxy statement/prospectus as the related company agreements, and agreed that all related company agreements would be transferred to BioVeris. THE RELATED TRANSACTION AGREEMENTS AND THE ONGOING COMMERCIAL AGREEMENTS Simultaneously with the execution and delivery of the merger agreement, IGEN, BioVeris, MSD, MST, Roche and certain of Roche's affiliates and the related companies also entered into the following agreements (although not all of the foregoing parties are parties to each agreement): the restructuring agreement; the post-closing covenants agreement; the tax allocation agreement; the ongoing litigation agreement; and a global consent and agreement. In addition, simultaneously with the execution and delivery of the merger agreement, IGEN and the license sub entered into the license agreement. Furthermore, IGEN, the license sub, BioVeris, MSD, MST, Roche and certain of Roche's affiliates entered into the following agreements (although not all of the foregoing parties are parties to each agreement): the improvements license agreement; the covenants not to sue; the PCR product license agreement; and the PCR services license agreement. Also simultaneously with the execution and delivery of the merger agreement, IGEN, BioVeris, MSD, MST, JW Consulting Services, L.L.C. and Mr. Jacob Wohlstadter entered into the MSD letter agreement and IGEN and Mr. Samuel Wohlstadter entered into the BioVeris preferred stock purchase agreement. ACCOUNTING TREATMENT OF THE RESTRUCTURING The transfer of certain assets and liabilities by IGEN to BioVeris will be accounted for based upon the authoritative guidance governing the distribution of nonmonetary assets to an entity under "common control." As such, IGEN's historical cost basis in the assets and liabilities transferred will become the initial recorded value of these assets and liabilities by BioVeris upon completion of the restructuring. FORM OF THE MERGER Subject to the terms and conditions of the merger agreement and in accordance with Delaware law, upon the completion of the merger, the merger sub, a wholly-owned subsidiary of Roche and a party to the merger agreement, will merge with and into IGEN. IGEN will survive the merger as a wholly-owned Delaware subsidiary of Roche. The license sub will remain a wholly-owned subsidiary of IGEN after the merger. MERGER CONSIDERATION Upon completion of the merger, each outstanding share of IGEN common stock (other than shares held by stockholders who validly exercise appraisal rights) will be converted into the right to receive $47.25 in cash, without interest, and one share of BioVeris common stock, except that any treasury stock and stock owned immediately prior to the completion of the merger by Roche or the merger sub, if any, will be canceled and retired and will cease to exist and no consideration will be delivered in exchange for these shares. Roche and the merger sub have represented in the merger agreement that they do not own any shares of IGEN common stock. The consideration to be received in the merger was determined through arms' length negotiations between Roche and IGEN. Upon completion of the merger, all outstanding options granted under IGEN's stock option plans, including unvested options, will be canceled and the holder of any such options will have the right to receive for each share covered by such option cash from Roche equal to the excess of $47.25 over the exercise price of such option (without interest) and one share of BioVeris common stock. 66 OWNERSHIP OF BIOVERIS FOLLOWING THE MERGER Immediately following the merger, IGEN's former stockholders will own 100% of the outstanding shares of BioVeris common stock. CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES The conversion of IGEN common stock into the right to receive cash and BioVeris common stock will occur automatically upon the completion of the merger. As soon as reasonably practicable after the completion of the merger, the exchange agent designated by Roche, will send a transmittal form to each former IGEN stockholder. The transmittal form will contain instructions for the surrender of IGEN common stock certificates. IGEN STOCKHOLDERS SHOULD NOT RETURN ANY STOCK CERTIFICATES WITH THEIR PROXY CARDS. After the completion of the merger, each certificate that previously represented shares of IGEN common stock will no longer be outstanding, will be automatically canceled and retired, will cease to exist and will represent only the right to receive cash and that number of shares of BioVeris common stock into which such shares are converted in the merger. Until holders of certificates previously representing IGEN common stock have surrendered those certificates to the exchange agent for exchange, those holders will not receive any dividends or distributions on the shares of BioVeris common stock into which such former IGEN shares have been converted with a record date after the date on which the merger is completed. When holders surrender such certificates, they will receive any dividends and distributions with a record date after the date on which the merger is completed and a payment date on or prior to the date of surrender, without interest. In the event of a transfer of ownership of IGEN common stock that is not registered in IGEN's transfer records, a certificate representing the proper number of shares of BioVeris common stock may be issued to a person other than the person in whose name the certificate so surrendered is registered if: - the certificate is properly endorsed or otherwise is in proper form for transfer; and - the person requesting the issuance pays any transfer or other taxes resulting from the issuance of shares of BioVeris common stock to a person other than the registered holder of the certificate. All cash and shares of BioVeris common stock issued in exchange for shares of IGEN common stock will be issued in full satisfaction of all rights relating to such shares of IGEN common stock. After the merger is completed, each stockholder exercising his or her appraisal rights will no longer have any rights as a stockholder of IGEN with respect to his or her shares, except for the right to receive payment of the judicially-determined fair value of his or her shares pursuant to Delaware law, if the stockholder has validly perfected and not withdrawn such right. EFFECTIVE TIME OF THE MERGER The merger will become effective upon the filing of the certificate of merger with the Secretary of State of the State of Delaware or such other time as Roche and IGEN shall agree and specify in the certificate of merger. The filing of the certificate of merger will occur as soon as practicable after satisfaction or waiver of the conditions to the completion of the merger described in the merger agreement, which IGEN and BioVeris expect will be shortly after of the special meeting. POST-CLOSING ARRANGEMENTS BETWEEN ROCHE, IGEN AND BIOVERIS The terms of the post-closing covenants agreement will govern the terms of the relationship between Roche and IGEN, on the one hand, and BioVeris, on the other hand, after the completion of the merger with respect to, among other things, indemnification rights, continuation of insurance and a standstill agreement by Roche with respect to BioVeris. For a more complete description of the terms of the post- 67 closing covenants agreement, see "Post-Closing and Other Arrangements -- Post-Closing Covenants Agreement." The tax allocation agreement allocates responsibility among the parties for preparing and filing tax returns, and paying taxes. For a more complete description of the terms of the tax allocation agreement, see "Post-Closing and Other Arrangements -- Tax Allocation Agreement." The license agreement, the improvements license agreement and the PCR license agreements provide that certain ongoing commercial arrangements between BioVeris and certain affiliates of Roche will become effective simultaneously with the completion of the merger. The covenants not to sue provides that certain ongoing obligations of BioVeris and certain affiliates of Roche to forgo claims of patent infringement will become effective simultaneously with the completion of the merger. For a more complete description of the license agreement, the improvements license agreement, the PCR license agreements and the covenants not to sue, see "Commercial Agreements." NASDAQ STOCK EXCHANGE LISTING OF BIOVERIS COMMON STOCK It is a condition to the completion of the merger that the BioVeris common stock to be distributed to IGEN stockholders in the merger have been approved for listing on a national securities exchange, or approved for quotation on The NASDAQ National Market(R), in either case subject only to official notice of issuance. BioVeris common stock has been approved for quotation on The NASDAQ National Market(R) and will be registered under the Securities Exchange Act of 1934, as amended. DELISTING AND DEREGISTRATION OF IGEN COMMON STOCK After completion of the merger, IGEN common stock will be delisted from The NASDAQ National Market(R) and will be deregistered under the Securities Exchange Act of 1934, as amended. U.S. FEDERAL INCOME TAX CONSEQUENCES The following discussion, which is based on an opinion that IGEN received from its special counsel, Cravath, Swaine & Moore LLP, summarizes the material U.S. Federal income tax consequences of the receipt by IGEN stockholders of BioVeris common stock in connection with the merger and the concurrent exchange of shares of IGEN common stock for cash in the merger. The merger and the distribution of BioVeris common stock in conjunction with the merger, collectively, are referred to as the "transaction" in this discussion of U.S. Federal income tax consequences. This discussion is based on current law, including the Internal Revenue Code of 1986, as amended, which is referred to in this proxy statement/prospectus as the Code, existing and proposed Treasury regulations, and administrative rulings and pronouncements and court decisions, all of which are subject to change. Any such change, which may or may not be retroactive, could alter the tax consequences described herein. This summary only applies to stockholders who hold IGEN common stock as a capital asset within the meaning of Section 1221 of the Code (generally speaking, for investment purposes). In addition, this summary does not describe all the tax consequences that may be relevant to a stockholder in light of its particular circumstances and does not apply to certain types of IGEN stockholders, such as insurance companies, financial institutions, regulated investment companies, dealers in securities or currencies, tax-exempt organizations, holders of IGEN common stock who hold such stock as part of a position in a straddle, or as part of a hedging, conversion or other integrated transaction, stockholders who have a functional currency other than the U.S. dollar, S corporations, small business investment companies, real estate investment trusts or traders who use a mark-to-market method of accounting for their securities holdings. In addition, this summary does not address the U.S. Federal income tax consequences of the transaction to any IGEN stockholder who, for U.S. Federal income tax purposes, is a nonresident alien individual, foreign corporation, foreign partnership or foreign estate or trust, and does not address the tax consequences of the transaction under state, local or foreign tax laws. 68 ACCORDINGLY, IGEN STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE TAX CONSEQUENCES OF THE TRANSACTION, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE TRANSACTION, IN THEIR PARTICULAR CIRCUMSTANCES. The parties to the merger agreement intend that the transaction will constitute a single integrated transaction with respect to IGEN and its stockholders for U.S. Federal income tax purposes, consisting of the receipt of BioVeris common stock in redemption of a portion of a stockholder's outstanding IGEN common stock coupled with a cash purchase of such stockholder's remaining IGEN common stock by Roche in connection with the complete termination of the IGEN stockholder's interest in IGEN. IGEN has received an opinion from its special counsel, Cravath, Swaine & Moore LLP, to the effect that, and based on such opinion IGEN believes that, the transaction should be so treated for U.S. Federal income tax purposes and, therefore, that the receipt of both BioVeris common stock and the cash consideration in connection with the merger should qualify as taxable sales or exchanges of IGEN common stock. Unless otherwise specified, this discussion assumes that the transaction will be treated in the manner described above. Accordingly, the transaction will result in the following U.S. Federal income tax consequences: Each holder of IGEN common stock will recognize capital gain or loss, if any, equal to the difference between (1) the sum of the amount of cash received in the merger plus the fair market value of the BioVeris common stock received by such holder at the time of distribution of BioVeris common stock in connection with the merger and (2) the holder's adjusted basis in the IGEN common stock immediately prior to the transaction. - Such gain or loss will be capital gain or loss, and generally will be long-term capital gain or loss if the IGEN common stock exchanged in the transaction had been held for more than one year at the time of the transaction. - The amount and character of gain or loss will be computed separately for each block of IGEN common stock that was purchased by the stockholder in the same transaction. - The tax basis of the BioVeris common stock received by IGEN stockholders in the transaction will be equal to the fair market value of such stock at the time of the distribution of BioVeris common stock in connection with the merger. - The holding period of the BioVeris common stock received by IGEN stockholders in the transaction will commence on the day after the distribution of BioVeris common stock in connection with the merger. One reasonable method of determining the fair market value of the BioVeris common stock received by IGEN stockholders in the transaction would be to use the average of the high and low trading prices of BioVeris common stock on the first full day of trading following the distribution of BioVeris common stock in connection with the merger. Nevertheless, IGEN stockholders are urged to consult their own tax advisors regarding this matter. No ruling has been or will be sought from the U.S. Internal Revenue Service, or the IRS, in connection with the transaction, and the IRS could disagree with the characterization of the transaction as set forth above. In particular, the IRS could contend, and a court might agree, that the value of the BioVeris common stock received or the cash merger consideration received should be treated as a dividend, rather than as proceeds attributable to a sale or exchange of IGEN common stock, in which case the relevant IGEN stockholder would have to include the full amount of such dividend in its income without being able to offset its basis in its IGEN common stock against such dividend. IGEN stockholders are urged to consult their own tax advisors concerning the proper characterization of the transaction and the resulting tax consequences to them, including, if the transaction is treated as giving rise to a dividend, the availability of preferential rates of taxation under recently enacted legislation for dividends received by individuals and the treatment of their basis in their IGEN common stock. 69 An IGEN stockholder may be subject to "backup withholding" at a rate of 28% on payments (including, if and to the extent taxed as a dividend as described below, the distribution of BioVeris common stock) received in connection with the transaction unless such holder (1) provides a correct taxpayer identification number (which, in the case of an individual, is such stockholder's social security number) and any other required information to the exchange agent, or (2) is a corporation or comes within certain other exempt categories and, when required, demonstrates this fact, all in accordance with the requirements of the backup withholding rules. If an IGEN stockholder does not provide a correct taxpayer identification number, such stockholder, in addition to being subject to backup withholding may be subject to penalties imposed by the IRS. Any amount paid as backup withholding does not constitute an additional tax and will be creditable against such stockholder's U.S. Federal income tax liability. IGEN stockholders should consult with their own tax advisors as to their qualifications for exemption from backup withholding and the procedure for obtaining such exemption. An IGEN stockholder may prevent backup withholding by completing an IRS Form W-9 or substitute W-9 and submitting it to the exchange agent for the merger when such stockholder submits such stockholder's stock certificate(s) following the completion of the merger. THE PRECEDING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE TRANSACTION AND DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR DISCUSSION OF ALL POTENTIAL TAX EFFECTS THAT MAY BE RELEVANT THERETO. THUS, IGEN STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS CONCERNING THE TAX CONSEQUENCES TO THEM OF THE TRANSACTION, INCLUDING THE PROPER CHARACTERIZATION OF THE TRANSACTION, TAX RETURN REPORTING REQUIREMENTS, THE APPLICABILITY AND EFFECT OF FOREIGN, FEDERAL, STATE, LOCAL, AND OTHER APPLICABLE TAX LAWS, AND THE EFFECT OF ANY PROPOSED CHANGES IN THE TAX LAWS. ANTITRUST MATTERS Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and related rules, certain transactions, including the merger, may not be completed unless certain waiting period requirements have been satisfied. On September 5, 2003, Roche and IGEN each filed a Notification and Report Form with the Antitrust Division of the Department of Justice and the Federal Trade Commission and Roche requested early termination of the required waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. Early termination of the required waiting period was granted effective September 29, 2003. At any time before or after the completion of the merger, the Antitrust Division, the Federal Trade Commission or others could take action under the antitrust laws, including seeking to prevent the merger, to rescind the merger or to conditionally approve the merger upon the divestiture of substantial assets of Roche or IGEN. There can be no assurance that a challenge to the merger on antitrust grounds will not be made or, if such a challenge is made, that it would not be successful. See "The Merger Agreement -- Conditions." APPRAISAL RIGHTS The following summary of the provisions of Section 262 of the Delaware General Corporation Law, or Section 262, is not intended to be a complete statement of the provisions and is qualified in its entirety by reference to the full text of Section 262, a copy of which is attached to this proxy statement/prospectus as Annex 17 and is incorporated into this summary by reference. Under Delaware law, if the merger is completed, each holder of record of IGEN common stock who: - files written notice with IGEN of an intention to exercise rights to appraisal of his, her or its shares prior to the taking of the vote on the merger at the IGEN special meeting; - does not vote in favor of the merger; - holds his, her or its shares on the date the merger is completed; and - follows the procedures set forth in Section 262; 70 will be entitled to be paid for his, her or its shares of IGEN common stock by the surviving corporation the fair value in cash of the shares of IGEN common stock. The fair value of shares of IGEN common stock will be determined by the Delaware Court of Chancery, exclusive of any element of value arising from the merger. The shares of IGEN common stock with respect to which holders have perfected their appraisal rights in accordance with Section 262 and have not effectively withdrawn or lost their appraisal rights are referred to in this proxy statement/prospectus as the dissenting shares. Within ten days after the completion of the merger, IGEN, as the surviving corporation in the merger, must mail a notice to all stockholders who have complied with the first and second bullet above notifying such stockholders of the completion of the merger. Within 120 days after the completion of the merger, such holders of IGEN common stock may file a petition in the Delaware Court of Chancery demanding appraisal of their shares. Failure to file this petition in a timely way will result in the loss of appraisal rights. Notwithstanding the foregoing, at any time, within 60 days of the completion of the merger, such stockholders may withdraw their demand for appraisal. Within 120 days after the completion of the merger, the holders of dissenting shares may also, upon written request, receive from IGEN a statement setting forth the aggregate number of shares not voted in favor of the merger and with respect to which demands for appraisals have been received and the aggregate number of holders of such shares. Appraisal rights are available only to the record holder of shares. If you wish to exercise appraisal rights but have a beneficial interest in shares which are held of record by or in the name of another person, such as a broker or nominee, you should act promptly to cause the record holder to follow the procedures set forth in Section 262 to perfect your appraisal rights. A demand for appraisal should be signed by or on behalf of the stockholder exactly as the stockholder's name appears on the stockholder's stock certificates. If the shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, the demand should be executed in that capacity, and if the shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including one or more joint owners, may execute a demand for appraisal on behalf of a record holder; however, in the demand the agent must identify the record owner or owners and expressly disclose that the agent is executing the demand as an agent for the record owner or owners. A record holder such as a broker who holds shares as nominee for several beneficial owners may exercise appraisal rights for the shares held for one or more beneficial owners and not exercise rights for the shares held for other beneficial owners. In this case, the written demand should state the number of shares for which appraisal rights are being demanded. When no number of shares is stated, the demand will be presumed to cover all shares held of record by the broker or nominee. If any holder of IGEN common stock who demands appraisal of his, her or its shares under Section 262 fails to perfect, or effectively withdraws or loses the right to appraisal, his, her or its shares will be converted into a right to receive cash and the number of shares of BioVeris common stock in accordance with the terms of the merger agreement. Dissenting shares lose their status as dissenting shares if: - the merger is abandoned; - the dissenting stockholder fails to file a written notice with IGEN of an intention to exercise rights to appraisal of his, her or its shares prior to the taking of the vote on the merger at the IGEN special meeting; - the dissenting shares are voted in favor of the merger; - neither IGEN nor the stockholder files a petition or intervenes in a pending action within 120 days after the completion of the merger; or - the stockholder delivers to IGEN, as the surviving corporation, within 60 days of the effective date of the merger, or thereafter with IGEN's approval, a written withdrawal of the stockholder's demand for appraisal of the dissenting shares, although no appraisal proceeding in the Delaware Court of Chancery may be dismissed as to any stockholder without the approval of the court. 71 If an appraisal petition is properly filed, after determining which stockholders are entitled to appraisal, the Delaware Court of Chancery will appraise the "fair value" of their shares of IGEN common stock, excluding any element of value arising from the accomplishment or expectation of the merger, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. The Delaware Court of Chancery will determine the amount of interest, if any, to be paid upon the amounts to be received by IGEN's stockholders whose shares have been appraised. IGEN'S STOCKHOLDERS CONSIDERING THE EXERCISE OF APPRAISAL RIGHTS SHOULD BE AWARE THAT THE FAIR VALUE OF THEIR SHARES OF IGEN COMMON STOCK AS DETERMINED UNDER SECTION 262 COULD BE MORE THAN, THE SAME AS OR LESS THAN THE VALUE OF THE MERGER CONSIDERATION THEY WOULD RECEIVE PURSUANT TO THE MERGER AGREEMENT IF THEY DID NOT SEEK APPRAISAL OF THEIR SHARES OF IGEN COMMON STOCK AND THAT INVESTMENT BANKING OPINIONS AS TO THE FAIRNESS OF THE MERGER CONSIDERATION FROM A FINANCIAL POINT OF VIEW ARE NOT OPINIONS AS TO THE FAIR VALUE OF SUCH COMMON STOCK UNDER SECTION 262. The Delaware Supreme Court has stated that "proof of value by any techniques or methods that are generally considered acceptable in the financial community and otherwise admissible in court" should be considered in the appraisal proceedings. The costs of the appraisal action may be determined by the Delaware Court of Chancery and taxed upon the parties as the court deems equitable. The court may also order that all or a portion of the expenses incurred by any stockholder in connection with an appraisal, including, without limitation, reasonable attorneys' fees and the fees and expenses of experts utilized in the appraisal proceeding, be charged pro rata against the value of all of the shares entitled to appraisal. Failure to follow the steps required by Section 262 for perfecting appraisal rights may result in the loss of appraisal rights. If an IGEN stockholder has lost his, her, or its appraisal rights, such stockholder will be entitled to receive the consideration with respect to the holder's dissenting shares in accordance with the merger agreement. In view of the complexity of the provisions of Section 262, IGEN stockholders who are considering objecting to the merger should consult their own legal advisors. IGEN EMPLOYEE BENEFITS MATTERS IGEN has adopted a termination protection program, the purpose of which is to encourage the named executive officers and 31 other key employees who participate in the program to continue as employees in the event of a "change of control" of IGEN, as defined in the termination protection program. The termination protection program provides that in the event a covered employee's employment is terminated without "cause" or the employee resigns for "good reason" within 30 months following a "change of control" of IGEN, or a covered employee's employment is terminated prior to a "change of control" at the request of a party involved in such "change of control" or otherwise in connection with or in anticipation of a "change of control," then the employee shall be entitled to receive a cash payment equal to 1.5 to 3 times the sum of the employee's annual salary plus bonus (3 times in the case of the named executive officers). Subject to certain exceptions, "good reason" means, for purposes of the termination protection program, - a decrease in (or failure to increase in accordance with the terms of any employment contract) the covered employee's base salary or bonus opportunity, - a diminution in the aggregate employee benefits and perquisites provided to the covered employee, - a diminution in the covered employee's title, reporting relationship, duties or responsibilities, - relocation of the covered employee's primary office more than 35 miles from its current location, or - the failure by any successor to the company to explicitly assume the termination protection program and IGEN's obligations thereunder. The termination protection program also provides that covered employees are entitled to continued welfare and pension benefits for up to 18 months (or in the case of the named executive officers, for up to 36 months (or life, with respect to medical and dental benefits and annual comprehensive physical)). In addition, the termination protection program provides reimbursement for outplacement services and provides a gross-up for any "parachute" excise tax imposed on payments made under the termination 72 protection program, and for the advancement of costs and expenses incurred by the employee related to the termination protection program. As a result of the restructuring, BioVeris will assume IGEN's liabilities and obligations under the IGEN termination protection program. BioVeris intends to terminate the IGEN termination protection program and replace it with a similar termination protection program. For a more complete description of BioVeris's termination protection program see "Management -- Executive Compensation -- BioVeris Termination Protection Program." The completion of the merger will not constitute a "change of control" under the termination protection program to the extent that BioVeris offers "qualifying positions" to employees covered by the termination protection program. In the restructuring agreement, effective upon completion of the merger, BioVeris has agreed to offer to each employee who participates in the termination protection program employment in a "qualifying position," as defined in the termination protection program. At such time, BioVeris has also agreed to offer to each employee of IGEN who does not participate in the termination protection program substantially comparable employment to the employment of such employee immediately prior to completion of the merger. Nothing contained in the restructuring agreement relating to such agreements by BioVeris will confer on any employee any right to continued employment after the completion of the merger, and each employee will continue to be employed "at-will" subject to any requirements under applicable foreign law or any applicable individual agreement to the contrary. Upon completion of the merger, IGEN's executive officers will be entitled to receive a transaction bonus payment, contingent upon the executive officer providing a release of the respective obligations of IGEN and BioVeris under IGEN's termination protection program. See "Management -- Executive Compensation -- Transaction Bonus Payments." Effective upon completion of the merger, BioVeris will assume all of IGEN's employee benefits and compensation liabilities, other than liabilities related to IGEN's stock option plans. EFFECT ON OPTIONS AND WARRANTS RELATING TO IGEN COMMON STOCK OPTIONS Upon completion of the merger, all outstanding options granted under IGEN's stock option plans, including unvested options, will be canceled and the holder of any such options will have the right to receive for each share covered by such option cash from Roche equal to the excess of $47.25 over the exercise price of such option (without interest) and one share of BioVeris common stock. On the record date for the special meeting, options to acquire 1,462,906 shares of IGEN common stock with a weighted average exercise price of $18.46 per share were outstanding. WARRANTS Following the completion of the merger, the holder of outstanding IGEN warrants will, upon exercise, be entitled to: - receive from BioVeris the number of shares of BioVeris common stock and cash in lieu of fractional shares of BioVeris common stock as if such holder had exercised the warrants for the shares of IGEN common stock issuable upon exercise of the warrants immediately prior to the completion of the merger, and - receive from Roche or IGEN the amount of cash as if such holder had exercised the warrants for the shares of IGEN common stock issuable upon exercise of the warrants immediately prior to the completion of the merger. On the record date for the special meeting, warrants to purchase 282,258 shares of IGEN common stock with an exercise price of $31.00 per share were outstanding. These warrants are held by LBI Group Inc., an affiliate of Lehman Brothers, OTA Limited Partners and Susquehanna Capital Group. None of the warrant holders is an affiliate of BioVeris or related to, or an affiliate of, any of BioVeris's officers or directors. 73 RESTRUCTURING AGREEMENT This is a summary of the material terms of the restructuring agreement. The complete restructuring agreement is attached as Annex 1 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire restructuring agreement carefully. GENERAL BioVeris is a newly formed wholly-owned subsidiary of IGEN organized for purposes of the merger and related transactions. Simultaneously with the execution of the merger agreement, BioVeris and IGEN entered into the restructuring agreement. The completion of the restructuring of IGEN as contemplated by the restructuring agreement is a condition to the completion of the merger. IGEN will not proceed with the merger unless the restructuring is completed. THE RESTRUCTURING Prior to the completion of the merger, IGEN will complete the restructuring. As part of the restructuring, BioVeris will assume IGEN's biodefense, life science and industrial product lines as well as IGEN'S opportunities in the clinical diagnostics and healthcare fields, and will own IGEN's intellectual property, IGEN's interests in MSD, cash and certain other rights and licenses currently held by IGEN. IGEN will retain IGEN's remaining businesses, assets and obligations, primarily representing its clinical testing business, including: - worldwide, non-exclusive, fully-paid, royalty-free rights and license to commercialize certain ECL-based immunochemistry systems in the specific clinical testing field generally described as the human in vitro diagnostics field; - IGEN's physicians' office laboratory business, including the continued right to distribute clinical tests to physicians' office laboratories, the retention of all of the recorded assets and liabilities of the physicians' office laboratory business and the continuation of customer relationships and access to customers through customer contracts; - unpublished patent applications and technical information of Hitachi High Technology Corporation; and - certain trademarks, including the "IGEN" name and derivatives of "IGEN," including ORIGEN(R) and PATHIGEN(R). Upon completion of the merger, BioVeris will become an independent, publicly-traded company owned by IGEN stockholders. BioVeris will have the assets described above, as well as certain ongoing commercial agreements with affiliates of Roche. Pursuant to its obligations under the restructuring agreement, IGEN is seeking the consent of the U.S. government for the transfer to BioVeris of 22 completed contracts that have expired or for which all obligations have been satisfied. IGEN is seeking this consent because under the restructuring agreement these contracts and the associated liabilities are required to be transferred to BioVeris. BioVeris does not expect that any material liabilities will arise from the transfer of the 22 completed contracts from IGEN to BioVeris. TRANSFER OF ASSETS Prior to the completion of the merger, IGEN will contribute, convey, assign, transfer and deliver, or cause to be contributed, conveyed, assigned, transferred and delivered, to BioVeris, all of IGEN's or its applicable subsidiaries' rights, title and interest in and to the assets of IGEN or its applicable subsidiaries, other than specified assets described below that will remain with IGEN. 74 Assets that will transfer to BioVeris include: - all assets that will not remain with IGEN, including IGEN's biodefense, life science and industrial product lines, IGEN's intellectual property, IGEN's interests in MSD and certain other rights and licenses held by IGEN; - shares of stock in subsidiaries of IGEN other than the license sub and BioVeris; - the license agreement and IGEN's rights, title and interest under such license agreement (other than any right, title and interest of the license sub); - the improvements license agreement and IGEN's rights, title and interest under such improvements license agreement; - BioVeris's rights and interests under the merger agreement and the related transaction agreements; - BioVeris's rights and interests under the covenants not to sue and the PCR license agreements; - any and all names, imprints, trademarks, trade names, trade name rights, trade dress, domain names, service marks, service mark rights and service names, whether or not registered, including all common law rights and all goodwill associated therewith, in each case, except the IGEN name or any of the foregoing that include or are derivatives of the IGEN name; and - copies of certain identified records that will be retained by IGEN, including the minute books of IGEN, the financial, accounting and tax records of IGEN, all filings made by IGEN with the Securities and Exchange Commission and NASDAQ, all filings and other documentation relating to the IGEN name and its derivatives, certain litigation files of IGEN, all documentation relating to the assets and liabilities which are to remain with IGEN following the restructuring and all documentation relating to the IGEN stock plans. The following assets will remain with IGEN following the restructuring: - all claims, defenses and judgments arising out of the Roche litigation and the patent infringement suits brought by IGEN against Roche Diagnostics in Maryland and Germany; - certain identified IGEN records, including the minute books of IGEN, the financial, accounting and tax records of IGEN, all filings made by IGEN with the Securities and Exchange Commission and NASDAQ, all filings and other documentation relating to the IGEN name and its derivatives, certain litigation files of IGEN, all documentation relating to the assets and liabilities which are to remain with IGEN following the restructuring and all documentation relating to the IGEN stock plans; - IGEN's limited liability company interests in the license sub; - the license sub's rights and interests under the license agreement and the covenants not to sue; - IGEN's rights and interests under the merger agreement and the related transaction agreements; - the IGEN name and all other names, imprints, trademarks, trade names, trade name rights, trade dress, domain names, service marks, service mark rights and service names of IGEN and its subsidiaries, whether or not registered, that include or are derivatives of the IGEN name; - IGEN's bank accounts (but not any cash in such bank accounts); - all rights under IGEN's insurance policies, subject to certain exceptions; - certain identified permits of IGEN; - certain identified contracts (including various securities purchase agreements and registration rights agreements); - the existing agreements between IGEN and Roche or their respective affiliates, which are referred to in this proxy statement/prospectus as I/R agreements, other than certain identified agreements 75 that will be transferred to BioVeris, which are referred to in this proxy statement/prospectus as the BioVeris I/R agreements; - all of the unpublished patent applications and technical information of Hitachi High Technologies Corporation provided to Roche Diagnostics, which in turn Roche Diagnostics has provided to IGEN prior to the date of the restructuring agreement; - the note pursuant to which Roche will loan to IGEN $214 million minus the amount of cash received by IGEN from July 24, 2003 to two business days before completion of the merger from the exercise of IGEN stock options and warrants, which is referred to in this proxy statement/prospectus as the Roche note; - receivables from and inventory intended for transferred physicians' office laboratories; and - any cash IGEN receives from the exercise of IGEN stock options or warrants after the date that is two business days prior to completion of the merger, such cash. ASSUMPTION OF LIABILITIES At or prior to completion of the merger, BioVeris and/or one of BioVeris's subsidiaries will unconditionally assume and undertake to pay, satisfy and discharge all liabilities of IGEN arising from events, occurrences, actions, omissions, facts or circumstances occurring or existing prior to the completion of the merger, other than specified liabilities described below that will remain with IGEN. The following liabilities will remain with IGEN following the restructuring: - any liabilities of IGEN under any of the merger agreement or the related transaction agreements, other than liabilities for its breaches prior to the completion of the merger; - any liabilities of the license sub under the license agreement or the covenants not to sue, other than liabilities for its breaches prior to the completion of the merger; - any liabilities of IGEN owed to Roche or its affiliates, including under the I/R agreements, other than the BioVeris I/R agreements; - any liabilities of IGEN arising out of the Roche litigation and the patent infringement suits brought by IGEN against Roche Diagnostics in Maryland and Germany; - any liabilities of IGEN with respect to transferred physicians' office laboratories, other than liabilities arising from acts or omissions by IGEN prior to the completion of the merger; - any liabilities of IGEN pursuant to the Roche note described above; and - any liabilities of IGEN under any contracts retained by IGEN, subject to certain exceptions. CONVERSION; CAPITALIZATION OF BIOVERIS AND ITS SUBSIDIARIES On September 22, 2003, IGEN Integrated Healthcare, LLC was converted from a limited liability company into a corporation in accordance with Section 18-216 of the Delaware Limited Liability Company Act and simultaneously changed its name to BioVeris Corporation. Prior to completion of the merger, IGEN will cause the number of authorized shares of BioVeris common stock to be sufficient to complete the merger and related transactions. The restructuring agreement further provides that: - IGEN will determine, in its sole discretion, the identity of BioVeris's directors and officers; - following its conversion to a corporation, BioVeris may enter into a stockholder rights agreement; and - prior to completion of the merger, BioVeris may create one or more subsidiaries and may transfer any or all of its assets to such subsidiaries. 76 NONASSIGNABLE CONTRACTS; RETAINED CONTRACTS The restructuring agreement provides that it will not constitute an agreement to assign or transfer any permit, sales order, purchase order, open bid or other commitment or contract if an assignment or transfer of the same without consent or waiver of the other party would constitute a breach or in any way impair BioVeris's rights under such contracts. IGEN is obliged to use its reasonable best efforts to obtain all necessary consents and waivers to assign the applicable contracts to BioVeris, although IGEN is not required to pay any amount to any person from whom such consents or waivers may be required. If any consent or waiver is not obtained prior to the completion of the merger, then BioVeris will cooperate, at BioVeris's expense, with IGEN following the merger in any reasonable arrangement under which BioVeris will obtain the economic claims, rights and benefits under such contracts. Such reasonable arrangement may include the subcontracting, sublicensing or subleasing to BioVeris of any and all rights of IGEN against such other party arising out of a breach or cancellation by such other party and the enforcement by IGEN of such rights. To the extent that BioVeris is able to receive the economic claims, rights and benefits of such contracts, BioVeris will be responsible for any liabilities arising under such contracts. INTERCOMPANY ARRANGEMENTS All contracts, arrangements and commitments, whether oral or written, solely between IGEN and BioVeris, and their respective operating units, entered into prior to completion of the merger will terminate upon completion of the merger. In addition, at or before completion of the merger, IGEN will cause all intercompany indebtedness between BioVeris, on the one hand, and IGEN, on the other hand, to be canceled. USE OF NAME Within 30 days after the completion of the merger, BioVeris and its subsidiaries will take or cause to be taken all actions necessary to change the name of any of the BioVeris companies to a name that does not include the "IGEN" name and all derivatives thereof, including any name confusingly similar thereto. EMPLOYEE MATTERS BioVeris has agreed to offer to each employee who participates in IGEN's termination protection program employment in a "qualifying position" (as defined in such termination protection program) upon completion of the merger. BioVeris has also agreed to offer, upon completion of the merger, to each employee of IGEN who does not participate in the termination protection program substantially comparable employment to the employment of such employee by IGEN immediately prior to completion of the merger. Nothing contained in the restructuring agreement relating to such agreements by BioVeris will confer on any employee any right to continued employment after the completion of the merger, and each employee will continue to be employed "at-will" subject to any requirements under applicable foreign law or any applicable individual agreement to the contrary. Effective upon completion of the merger, BioVeris will assume all of IGEN's employee benefits and compensation liabilities, other than with respect to IGEN's stock plans. BioVeris will generally be entitled to amend or terminate any employee benefit plan that IGEN otherwise has the right to terminate. BioVeris agreed to reimburse IGEN for all costs and expenses reasonably incurred by IGEN pursuant to the employee plans transferred to BioVeris after completion of the merger. The merger and related transactions are not intended to constitute a termination of employment of any employee that would entitle such employee to receive severance or similar compensation and benefits. AMENDMENT AND TERMINATION Prior to the completion of the merger, for so long as the merger agreement remains in effect, the restructuring agreement may not be amended or modified, and no provision of it may be waived, without Roche's prior written consent. In the event the merger agreement is terminated pursuant to its terms, the restructuring agreement will automatically and simultaneously terminate and the restructuring will automatically and simultaneously be abandoned without BioVeris's approval or the approval of IGEN stockholders. 77 THE MERGER AGREEMENT This is a summary of the material provisions of the merger agreement. The complete merger agreement is attached as Annex 2 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire merger agreement carefully. THE MERGER Under the merger agreement, following the restructuring and the satisfaction or waiver of the other specified conditions, the merger sub, a wholly-owned subsidiary of Roche, will merge with and into IGEN, as a result of which IGEN will become a wholly-owned subsidiary of Roche. Upon completion of the merger BioVeris will become an independent, publicly-traded company owned by IGEN stockholders.

NO SOLICITATION; RECOMMENDATION OF THE IGEN BOARD OF DIRECTORS; SUPERIOR PROPOSALS IGEN agreed that it will not, and will not permit any of its representatives to, - directly or indirectly solicit, initiate or encourage the submission of any company takeover proposal (as described below), - enter into any agreement with respect to any company takeover proposal, - grant any waiver or release under any standstill or similar agreement with respect to any class of equity securities of IGEN or any subsidiary of IGEN, or - directly or indirectly, - participate in any discussions or negotiations with, or furnish any information with respect to, IGEN or any subsidiary of IGEN to any person that is seeking to make, or has made, any company takeover proposal or - afford access to the business, properties, assets, books or records of IGEN or any subsidiary of IGEN to, or otherwise cooperate in any way with, or knowingly assist, participate in, facilitate or encourage any effort by any person that is seeking to make, or has made, any company takeover proposal. However, if prior to obtaining IGEN stockholder approval, the IGEN board of directors receives an unsolicited company takeover proposal that the IGEN board of directors determines in good faith, after receipt of the advice of its financial advisor and outside legal counsel, is reasonably likely to result in a proposal that is, a "superior company proposal" (as described below), then IGEN and its representatives may provide information (subject to a confidentiality agreement) and participate in discussions or negotiations in connection with such company takeover proposal. IGEN must promptly advise Roche 80 orally and in writing of any company takeover proposal or any inquiry from a third party to an officer or director of IGEN with respect to the making of a company takeover proposal, the identity of the person making any such company takeover proposal or inquiry and the material terms of any such company takeover proposal or inquiry. The IGEN board of directors will not: - withdraw or modify in a manner adverse to Roche, or propose publicly to withdraw or modify in a manner adverse to Roche, the approval or recommendation of the merger agreement or the merger by the IGEN board of directors, unless the IGEN board of directors determines in good faith, after consultation with outside counsel, that it is necessary to do so in order to comply with its fiduciary duties; - approve any letter of intent or acquisition or other agreement relating to a company takeover proposal (other than a confidentiality agreement as described above); or - approve or recommend, or propose publicly to approve or recommend, any company takeover proposal. If, however, prior to obtaining IGEN stockholder approval, the IGEN board of directors receives a superior company proposal, then the IGEN board of directors may, having first complied with the notification requirements summarized above and taken into account any revised proposal from Roche, after three business day approve and recommend such superior company proposal and cause IGEN to terminate the merger agreement and enter into a definitive agreement with respect to such superior company proposal. IGEN - will, and will cause its subsidiaries to, and will instruct its representatives to, cease immediately and cause to be terminated all activities, discussions or negotiations, if any, with any persons conducted prior to the date of the merger agreement with respect to any company takeover proposal and - will promptly request each person, if any, that has executed a confidentiality agreement within the 12 months prior to the date of the merger agreement in connection with such person's consideration of any company takeover proposal to return or destroy all confidential information furnished to such person by or on behalf of IGEN or any subsidiary of IGEN. A "company takeover proposal" means - any proposal or offer for a merger, consolidation, dissolution, recapitalization or other business combination involving IGEN, - any proposal or offer to acquire in any manner, directly or indirectly, over 20% of the equity securities or consolidated total assets of IGEN, or - any other transaction the consummation of which would reasonably be expected to impede, prevent or materially delay the merger, in each case other than - the merger and related transactions, - the performance of obligations pursuant to the ongoing commercial agreements or - any transaction involving BioVeris or BioVeris's subsidiaries that will be consummated after completion of the merger. A "superior company proposal" means any bona fide, unsolicited written proposal to acquire, directly or indirectly, including pursuant to a tender or exchange offer, a merger, a consolidation, a liquidation or dissolution, a recapitalization or similar transaction, more than 50% of the combined voting power of the shares of IGEN common stock then outstanding or all or substantially all of the assets of IGEN and its 81 subsidiaries, taken as a whole, on terms which the IGEN board of directors determines in good faith to be more favorable to the holders of IGEN common stock than the merger and related transactions (after consultation with a financial advisor of nationally recognized reputation), taking into account all the terms and conditions of such proposal, including any break-up fees, expense reimbursement provisions and conditions to consummation, and the merger agreement (including any proposal by Roche to amend the terms of the merger and related transactions), and for which financing, to the extent required, is then fully committed or reasonably determined to be available by the IGEN board of directors. TERMINATION OF THE MERGER AGREEMENT The merger agreement may be terminated at any time prior to the completion of the merger, whether before or after receipt of the IGEN stockholder approval: - by mutual written consent of Roche, the merger sub, IGEN and BioVeris; - by either Roche or IGEN - if the merger does not occur on or before July 24, 2004, unless the failure to complete the merger is the result of a material breach of the merger agreement by the party seeking to terminate the merger agreement, - if any law preventing the merger comes into effect or if any governmental entity issues an order or injunction or takes any other action permanently preventing the completion of the merger and such order, injunction or other action will have become final and nonappealable, unless such order, injunction or other action is the result of a material breach of the merger agreement by the party seeking to terminate the merger agreement, or - if the IGEN stockholders do not adopt the merger agreement upon a vote at the IGEN stockholders meeting; - by Roche, if the IGEN board of directors - withdraws or adversely modifies its approval or recommendation of the merger agreement or the merger to the IGEN stockholders, or proposes publicly to do so, - fails to recommend to the IGEN stockholders that they adopt the merger agreement, or - approves or recommends any company takeover proposal, or proposes publicly to do so; - by IGEN - if the IGEN board of directors exercises its right described above to accept a superior company proposal, - if Roche breaches or fails to perform in any material respect any of its representations, warranties or covenants contained in the merger agreement, which breach or failure to perform, if capable of being cured, has not been cured within 30 days after the giving of written notice to Roche of such breach, or - if it has not received the $18,600,000 payment in respect of damages arising out of the Roche litigation, the $10,620,000 royalty payment due under the 1992 license agreement for the quarter ended June 30, 2003 or the monthly $5,000,000 payment due to it from Roche Diagnostics in accordance with the ongoing litigation agreement. FEES AND EXPENSES GENERAL The merger agreement provides that, except as otherwise provided in the merger agreement or in any related transaction agreement, all fees and expenses incurred in connection with the merger and related transactions will be paid by the party incurring such expenses. 82 TERMINATION FEE IGEN will pay to Roche a termination fee of $26.6 million if: - the merger agreement is terminated by IGEN because the IGEN board of directors received and accepted an unsolicited superior company proposal and IGEN then completes the transactions contemplated by such superior company proposal or any other company takeover proposal providing for the acquisition of over 50% of the stock or assets of IGEN; or - (1) the merger agreement is terminated by Roche because the IGEN board of directors withdrew or adversely modified its recommendation to the IGEN stockholders, or proposed publicly to do so, and (2) IGEN then consummates the transactions contemplated by a company takeover proposal providing for the acquisition of over 50% of the stock or assets of IGEN within 12 months after the termination of the merger agreement; or - (1) any person make a company takeover proposal for over 50% of the stock or assets of IGEN and (2) the merger agreement is terminated because the merger will not have occurred on or before July 24, 2004 (but only if the IGEN stockholder meeting has not been held by the date that is two days prior to such outside date) and (3) IGEN then consummates the transactions contemplated by a company takeover proposal providing for the acquisition of over 50% of the stock or assets of IGEN within 12 months after the termination of the merger agreement. In addition, IGEN agreed to reimburse Roche for all its reasonable expenses of up to $5 million incurred in connection with the merger agreement, the ongoing commercial agreements and the merger and related transactions in the event that the merger agreement is terminated for the reasons described in either the first or second bullets of the preceding paragraph.

From and after completion of the merger, Roche will indemnify, defend and hold harmless BioVeris and its affiliates, subsidiaries and representatives, which are referred to in this proxy statement/prospectus as the BioVeris indemnitees, from and against, and pay or reimburse the BioVeris indemnitees, for all losses, as incurred, to the extent: - relating to or arising from the business, assets or liabilities retained by IGEN in the restructuring, whether such losses relate to or arise from events, occurrences, actions, omissions, facts or circumstances occurring, existing or asserted before, at or after completion of the merger; - relating to or arising from specified contracts retained by IGEN with respect to such losses relating to or arising from events, occurrences, facts or circumstances relating to or arising from actions or omissions by IGEN occurring after completion of the merger that are inconsistent in any respect with any written instruction from BioVeris with respect to such retained contract; - relating to or arising from any untrue statement of a material fact contained in any of the filings in connection with the merger and related transactions required to be made with the Securities and Exchange Commission by IGEN or BioVeris, or any omission or alleged omission to state in any such filings a material fact required to be stated in such filings or necessary to make the statements in such filings, in light of the circumstances under which they were made, not misleading, but only with respect to statements made in the filings or incorporated by reference in the filings based upon information supplied by Roche or any of its affiliates or any of their respective representatives (including, after completion of the merger, IGEN and the subsidiaries of IGEN) specifically for inclusion or incorporation by reference in the filings; - relating to or arising from the breach by Roche or any of its affiliates (other than, prior to completion of the merger, IGEN, BioVeris or any of their affiliates) of any agreement or covenant contained in the merger agreement or any transaction agreement, whether such losses relate to or arise from events, occurrences, actions, omissions, facts or circumstances occurring, existing or asserted before, at or after completion of the merger; or - relating to or arising from the breach by IGEN of any agreement or covenant contained in the merger agreement or any related transaction agreement which is to be performed or complied with by it after completion of the merger. The post-closing covenants agreement also contains provisions governing indemnification procedures and limitations. The post-closing covenants agreement also provides that all indemnification payments shall be reduced to take account of the net present value of any net tax benefit realized by the indemnitee in connection with or otherwise arising from the incurrence of an indemnifiable loss. AGREEMENT NOT TO SOLICIT EMPLOYEES For a period of two years from and after completion of the merger, Roche will not, and will not permit its subsidiaries to, directly or indirectly, solicit for employment any individual employed by BioVeris, any of its subsidiaries or any of its respective divisions. It will not constitute a breach of the previous sentence if Roche or its subsidiaries make solicitations for employment by general advertisements in periodicals of broad distribution or other advertisement media of similar nature that are not specifically directed at BioVeris's employees. 91 INDEMNIFICATION OF DIRECTORS AND OFFICERS Roche will, to the fullest extent permitted by law, cause IGEN to honor all of its existing obligations to indemnify the current or former directors or officers of IGEN, whether pursuant to IGEN's certificate of incorporation or by-laws or individual indemnity agreements, for acts or omissions occurring prior to completion of the merger. From completion of the merger until the sixth anniversary of the merger, Roche will maintain in effect the current policies of directors' and officers' liability insurance maintained by IGEN with respect to claims arising from or related to events which occurred at or before completion of the merger. However, Roche will not be obligated to pay premiums in excess of 250% of the amount per annum required to be paid by IGEN in the twelve months ending December 12, 2003, provided, that, if the annual premiums exceed 250% of the amount per annum required to be paid by IGEN in the twelve months ending December 12, 2003, Roche will nevertheless be obligated to obtain such insurance and BioVeris will pay IGEN the amount of any such excess cost. IGEN has been advised by its directors' and officers' liability insurer that the total cost for such insurance would be 200% of the amount per annum required to be paid by IGEN in the twelve months ending December 12, 2003. LIMITATIONS ON CERTAIN CLAIMS BioVeris and Roche each agreed not to assert or pursue, and not to permit their respective affiliates to assert or pursue or encourage any other person to assert or pursue, either before or after the completion of the merger, any actions or claims against the other or their respective affiliates or current or former directors, officers, members of the board of managers, members, managers, employees, consultants, advisors, attorneys, trustees or agents, in each case based on acts or omissions occurring prior to the date of the merger agreement or after the date of the merger agreement and prior to the completion of the merger, claims except as required by subpoena or other judicial or legal process or as requested by any inquiry by a governmental entity, in each case only to the extent such inquiry or requirement to cooperate has not arisen as a result of its breach of this provision. This covenant, however, does not - prevent actions to enforce the merger agreement, any related transaction agreement, any ongoing commercial agreement, any I/R agreement, any BioVeris I/R agreement, any agreement entered into between IGEN, BioVeris or any of their respective affiliates, on the one hand, and any of Roche Diagnostics Corporation, Roche, the merger sub, Roche Diagnostics, F. Hoffmann-La Roche Ltd and Roche Molecular Systems, Inc. or any of their respective affiliates, on the other hand, after the date of the merger agreement but prior to the completion of the merger or any provision in those agreements in accordance with its terms, or - apply to acts or omissions that constitute fraud in the inducement with respect to the merger agreement, any related transaction agreement or any ongoing commercial agreement. STANDSTILL From the date of completion of the merger to the fourth anniversary of the date of completion of the merger, Roche will not and will not permit any of its affiliates to - acquire, agree to acquire or make any proposal to acquire, directly or indirectly, any securities or assets of BioVeris or any of its subsidiaries, except at BioVeris's unsolicited specific written request, - propose to enter into, directly or indirectly, any tender or exchange offer, merger or other business combination or similar transaction involving BioVeris or any of its subsidiaries, except at BioVeris's unsolicited specific written request, - form, join or in any way participate in a "group" (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934) with respect to any securities of BioVeris or any of its subsidiaries, 92 - enter into of any discussions, negotiations, arrangements, understandings or agreements (whether written or oral) with any other person regarding any possible purchase or sale of any securities or assets of BioVeris or any of its subsidiaries, - make, or in any way participate, directly or indirectly, in any "solicitation" of "proxies" (as such terms are used in the proxy rules of the Securities Exchange Commission) to vote, or seek to advise or influence any person with respect to the voting of, any securities of BioVeris or any of its subsidiaries, - call, or seek to call, a meeting of BioVeris's stockholders or initiate or propose any stockholder proposal or execute any written consent with respect to BioVeris, - otherwise act, alone or in concert with others, to seek or attempt to control or influence BioVeris's management, board of directors or policies (except to the extent conduct or settlement of litigation between Roche Diagnostics and IGEN might be deemed such an attempt), - disclose any intention, plan or arrangement inconsistent with the foregoing or - advise, assist or encourage any other persons in connection with any of the foregoing. During the standstill period, Roche will not - request, directly or indirectly, that BioVeris or any of its representatives amend or waive any provisions of the standstill, or - take any action which could reasonably be expected to require BioVeris to make a public announcement regarding the possibility of a business combination, merger or similar transaction other than the merger and related transactions and the transactions contemplated by the ongoing commercial agreements. TRANSFERRED CUSTOMERS From and after completion of the merger, BioVeris will assume IGEN's rights to be indemnified for product liability claims arising from sales made prior to the completion of the merger under the supply, services and support agreement dated as of May 1, 2000 between IGEN and Roche Diagnostics relating to transferred physicians' office laboratory customers that had been transferred to IGEN from Roche pursuant to an injunction by the District Court prohibiting Roche Diagnostics from marketing its Elecsys products in physicians' office laboratories and requiring Roche Diagnostics to escrow all revenues from past sales to physicians' office laboratories pending the outcome of the Roche litigation and to transfer all of its current Elecsys customers constituting physicians' office laboratories to IGEN. PCR LICENSE PAYMENT BioVeris agreed to make the $50 million PCR license payment in accordance with the PCR product license agreement. For a more complete description of the PCR product license agreement see "Commercial Agreements -- PCR License Agreements." MUTUAL RELEASE Roche, on the one hand, and IGEN and BioVeris, on the other hand, release, as of immediately prior to completion of the merger, the other and its past, present and future affiliates and its and their respective successors, predecessors, assigns, heirs, officers, directors, members of the board of managers, members, managers, employees, consultants and trustees from, and agree not to bring any action against the foregoing related to, all debts, demands, actions, causes of action, suits, accounts, covenants, contracts, agreements, torts, damages, claims, defenses, offsets, judgments, demands and liabilities whatsoever which have been or could have been asserted against the other person arising out of or relating to events or actions taken by such other person prior to the completion of the merger.

Hoffmann-La Roche Ltd and Roche Molecular Systems, Inc. or any of their respective affiliates, on the other hand, after the date of the merger agreement but prior to the completion of the merger or any provision in those agreements in accordance with its terms or - apply to any act or omission which constitutes fraud in the inducement with respect to the merger agreement, any related transaction agreement or any ongoing commercial agreement. OTHER COVENANTS The post-closing covenants agreement also contains other covenants relating to, among other things, insurance, records, access, public announcements, preservation of privileges and confidentiality. In addition, neither BioVeris nor Roche will consolidate with or merge into, or sell, convey transfer or lease, in one transaction or a series of related transactions, all or substantially all of its assets to, any person, unless the resulting, surviving or transferee person expressly assumes in writing all of its obligations under the post-closing covenants agreement. TERMINATION In the event the merger agreement is terminated pursuant to its terms prior to the completion of the merger, the post-closing covenants agreement will automatically and simultaneously terminate. In the event of such termination, no party will have any liability to any other party pursuant to the post-closing covenants agreement. In addition, Roche, BioVeris and IGEN agree that the completion of the merger will not constitute a termination of the post-closing covenants agreement. TAX ALLOCATION AGREEMENT This is a summary of the material provisions of the tax allocation agreement. The tax allocation agreement is attached as Annex 4 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire tax allocation agreement carefully. GENERAL Simultaneously with the execution of the merger agreement, Roche, the merger sub, IGEN and BioVeris entered into the tax allocation agreement. In general, the tax allocation agreement allocates responsibility among the parties for preparing and filing tax returns and paying taxes. ALLOCATION OF RESPONSIBILITY FOR TAXES Taxes Attributable to Pre-Merger Periods (Other Than Transaction Taxes). The tax allocation agreement provides that IGEN will prepare and file all tax returns of IGEN relating to pre-merger periods, with very limited exceptions. IGEN must prepare such returns in accordance with its historic practices and in accordance with the representations, covenants and other provisions of the tax allocation agreement. Except as described below under "-- Transaction Taxes", BioVeris will be liable for, will indemnify Roche and IGEN against, and will be entitled to receive and retain all refunds of, any taxes of IGEN attributable to pre-merger periods. Transaction Taxes. The tax allocation agreement provides that Roche and IGEN will be solely liable for, will jointly and severally indemnify BioVeris against, and will be entitled to receive and retain all refunds of, taxes (other than transfer taxes) directly or indirectly resulting from, arising in connection with or otherwise related to the merger and related transactions, any transaction undertaken to prepare for the merger and related transactions and any of the actions taken pursuant to the ongoing litigation agreement. This agreement also provides for BioVeris to make a payment to IGEN of up to $20 million. The amount 94 of the payment will depend upon the average of the high and the low trading prices of BioVeris common stock on the first day of trading after the completion of the merger. A payment will be due if such average is at least approximately $11.41 per share and the maximum payment will be due if such average exceeds approximately $13.28, in each case based on the assumption that BioVeris will have $205 million in cash and cash equivalents immediately after completion of the merger and prior to making any payments due pursuant to the related transaction agreements, the ongoing commercial agreements or the MSD letter agreement. The distribution of BioVeris stock will be a taxable transaction for IGEN and the purpose of this payment is for BioVeris to share in a portion of the tax that IGEN might incur as a result of that distribution. The formula, which takes into account the expected approximate tax basis and tax rate that would be used in IGEN's calculation of its tax, was negotiated by Roche and IGEN as part of the overall negotiation of the merger. Taxes Attributable to Post-Merger Periods. The tax allocation agreement provides that IGEN will prepare and file all tax returns relating to IGEN and pay all taxes of IGEN attributable to post-merger periods, and BioVeris will prepare and file all tax returns relating to BioVeris and pay all taxes of BioVeris attributable to post-merger periods. Indemnification for Breach of Representations and Covenants. The tax allocation agreement provides that the parties will indemnify each other for breach of the representations and covenants set forth in the agreement. ONGOING LITIGATION AGREEMENT This is a summary of the material provisions of the ongoing litigation agreement. The ongoing litigation agreement is attached as Annex 5 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire ongoing litigation agreement carefully. GENERAL Simultaneously with the execution of the merger agreement, IGEN, Roche Diagnostics and Roche Diagnostics Corporation entered into the ongoing litigation agreement. Meso Scale Technologies, LLC. and Meso Scale Diagnostics, LLC. joined the ongoing litigation agreement to confirm their agreement with specified provisions of the ongoing litigation agreement. The ongoing litigation agreement sets forth agreements of the parties relating to the litigation among them. STANDSTILL Maryland Patent Action. Following execution of the ongoing litigation agreement, IGEN and Roche filed the "Maryland joint motion to stay" (in the form attached as Appendix B to the ongoing litigation agreement) pursuant to which IGEN and Roche agreed to stay any proceedings relating to IGEN International Inc. v. Roche Diagnostics GmbH and Roche Diagnostics Corp., Case No. PJM 03CV2000 (D. Md. filed July 9, 2003), and any successor action, which is referred to in this proxy statement/prospectus as the Maryland patent action. IGEN and Roche agreed, until the earlier of completion of the merger or termination of the merger agreement, to take such further actions as may be reasonably necessary, appropriate, desirable, or required in order to facilitate the District Court entering and maintaining the order contemplated by the Maryland joint motion to stay. On August 1, 2003 IGEN and Roche Diagnostics filed the Maryland joint motion to stay, which was promptly granted by the District Court. Roche Litigation. Under the ongoing litigation agreement, Roche agreed that it will file or cause to be filed any and all motions, pleadings and documents in IGEN International Inc. v. Roche Diagnostics GmbH, Case No. PJM 97CV3461 (D. Md. filed October 15, 1997), appealed as Appeal No. 02-1537 (4th Circuit decided July 9, 2003), and any successor action which is referred to in this proxy statement/ 95 prospectus as the Roche litigation, appropriate or necessary to withdraw its petition for a panel rehearing filed on July 23, 2003. Each of Roche and IGEN agreed that: - it will not take any action or file any additional motions or pleadings in the Roche litigation, including any further motions for rehearing or rehearing en banc that may be or could be filed with the Appellate Court, or any petition for writ of certiorari to the United States Supreme Court, in the Roche litigation; - it will take any and all action that may reasonably be required or necessary in order to stay, or withdraw with the right to refile, any motion filed prior to the date of the ongoing litigation agreement in the District Court with respect to the Roche litigation that remains pending; and - any time periods or limitations with respect to the right of any party to appeal any order of the District Court entered in the Roche litigation on or after the date of the ongoing litigation agreement will be tolled until the earlier of completion of the merger or termination of the merger agreement. On July 25, 2003, Roche Diagnostics filed a motion to withdraw its petition for rehearing and on August 1, 2003, the Appellate Court granted that motion. The Appellate Court returned the matter to the District Court on August 8, 2003 for entry of a final order consistent with the Appellate Court ruling. The parties have not made any filing with the District Court, and the District Court has not issued any further orders in this case. German Patent Action. Roche and IGEN agreed that IGEN will be authorized to proceed to serve or have served on Roche, and that Roche will be authorized to indicate to the court its intention to defend itself in, IGEN International Inc. v. Roche Diagnostics GmbH and Roche Diagnostics Inc., File No. LG Dusseldorf 4b O 258/03 (Dusseldorf, Germany filed July 9, 2003) and any successor action, which is referred to in this proxy statement/prospectus as the German patent action. Roche and IGEN further agreed to jointly take all steps necessary to stay the German patent action after service especially by requesting a stay ("Ruhen des Verfahrens gemabeta sec. 251 ZPO") until the earlier of completion of the merger or termination of the merger agreement by filing the German joint motion to stay (in the form attached as Appendix A to the ongoing litigation agreement) pursuant to which IGEN and Roche agree to stay any proceedings relating to the German patent action, within a week after the date of the ongoing litigation agreement. Roche agreed that it will refrain from taking any steps to achieve a dismissal of the German patent action at any time before the earlier of completion of the merger or termination of the merger agreement. However, to the extent that dismissal occurs before the earlier of completion of the merger or termination of the merger agreement, Roche and IGEN will take all steps necessary promptly to re-instate the German patent action through to the earlier of completion of the merger or termination of the merger agreement. On August 8, 2003, IGEN and Roche Diagnostics jointly made the required filings to obtain a stay of the German patent action. No further action is required of the parties or the court in order to stay the proceedings. Subsequent Actions. IGEN will, upon advice of counsel in order to preserve its legal rights being asserted in the Maryland patent action and the German patent action, be permitted to withdraw and promptly re-file either of the Maryland patent action and the German patent action and such withdrawal and re-filing will not be a violation of any of IGEN's obligations under the ongoing litigation agreement. Roche agreed that it will not object to the withdrawal and re-filing of a complaint or other pleading in either of the Maryland patent action or the German patent action. Promptly after completion of the merger: - IGEN will withdraw and terminate each of the Maryland patent action and the German patent action and use its reasonable best efforts to cause the dismissal of such actions as soon as practicable after such withdrawal and termination; and 96 - Roche will cooperate and use its reasonable best efforts to cause the dismissal of the Maryland patent action and the German patent action. Any pleadings, motions, filings and other submissions to or with the courts having jurisdiction over the Maryland patent action and the German patent action that would adversely impact the intellectual property of BioVeris will require BioVeris's consent, which shall not be unreasonably withheld, conditioned or delayed. ONGOING OBLIGATIONS AND COVENANTS Covenant of Cooperation. Each of Roche and IGEN will cooperate with the other in all reasonable respects, including in the preparation, execution and filing of all necessary or appropriate papers with the appropriate forums, to consummate and carry out the purposes and intent of each of the standstill provisions summarized above. In addition, Roche and IGEN agreed that prior to the earlier of completion of the merger or termination of the merger agreement it will take all further necessary steps and actions before the courts having jurisdiction over the Maryland patent action and the German patent action to avoid dismissal of the complaints pending in each of those cases prior to the earlier of completion of the merger or termination of the merger agreement. Covenant Not to Sue. IGEN will not commence any new patent suit or prosecute any patent suit against Roche for any acts of Roche occurring between the date of termination of the 1992 license agreement through to the earlier of completion of the merger or termination of the merger agreement that, if taken prior to termination of the 1992 license agreement, would have been within the scope of the license granted under the 1992 license agreement. However, nothing in the ongoing litigation agreement will preclude IGEN from asserting or filing, and IGEN reserves the right to assert and file, any claim, suit, action and proceeding against Roche and any of its affiliates for any acts taken after the date of termination of the 1992 license agreement that are not within the scope of the license granted under the 1992 license agreement. Compliance with Judgment. Until the completion of the merger, each of IGEN and Roche will comply with all of its obligations under and in respect of the final judgment entered by the District Court in the Roche litigation or any final judgment entered not inconsistent with the mandate to be returned by the Appellate Court in connection with the opinion of the Appellate Court. In addition, each of IGEN and Roche will take all action necessary to cause the District Court to enter a final judgment not inconsistent with the mandate to be returned by the Appellate Court in connection with the opinion of the Appellate Court. PAYMENTS Under the ongoing litigation agreement, Roche agreed to make the following payments to IGEN: - not later than two business days after the date of the ongoing litigation agreement, $18.6 million as full payment of the compensatory damages awarded in the Roche litigation; - not later than two business days after the date of the ongoing litigation agreement, $10.62 million as full payment to IGEN for royalties due and payable under the 1992 license agreement for sales made in the second calendar quarter ended June 30, 2003; - not later than two business days after the date of the ongoing litigation agreement, $5.0 million as partial consideration for the ongoing litigation agreement; and - on the last business day of each month during the term of the ongoing litigation agreement, commencing in August 2003, $5.0 million as partial consideration for the ongoing litigation agreement. Roche has made the payments to IGEN required to have been made under the terms of the ongoing litigation agreement as of the date of this proxy statement/prospectus. 97 TERM AND TERMINATION Term. The ongoing litigation agreement will remain in full force and effect from the date of the ongoing litigation agreement until the earlier to occur of completion of the merger or termination of the merger agreement. Termination. IGEN may, in its sole discretion, terminate the ongoing litigation agreement if Roche fails to make any payment when due, which failure has not been cured within ten days after IGEN has delivered to Roche written notice thereof. GLOBAL CONSENT AND AGREEMENT This is a summary of the material provisions of the global consent and agreement. The global consent and agreement is attached as Annex 6 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire global consent and agreement carefully. GENERAL MSD is a joint venture formed by MST and IGEN in 1995. MSD was formed for the development, manufacture, marketing and sale of products utilizing a proprietary combination of MST's multi-array technology together with IGEN's ECL technology. MST is a company established and wholly-owned by Mr. Jacob Wohlstadter, a son of Mr. Samuel Wohlstadter, IGEN's and BioVeris's chief executive officer. In August 2001, IGEN amended the MSD joint venture agreement and certain license and other agreements with MSD and MST to continue the MSD joint venture and entered into various related agreements, which are referred to in this proxy statement/prospectus as the MSD agreements. An independent committee of the IGEN board of directors, with the advice of independent advisors and counsel, negotiated and approved the MSD agreements. Simultaneously with the execution of the merger agreement, BioVeris, IGEN, Roche, MSD, MST, Mr. Jacob Wohlstadter and JW Consulting Services, L.L.C. entered into the global consent and agreement, pursuant to which, among other things, Mr. Jacob Wohlstadter, JW Consulting Services, L.L.C., MSD and MST, or the consenting parties, consented to the transfer of IGEN's interest in MSD to BioVeris. CONSENT Each of the consenting parties consented to each of the merger agreement, the related transaction agreements and the ongoing commercial agreements and to the completion of the merger and related transactions, and granted all waivers and consents that are necessary under the MSD agreements to permit the completion of the merger and related transactions and the performance by IGEN, BioVeris and each consenting party of their obligations under the merger agreement, the related transaction agreements and the ongoing commercial agreements in accordance with their terms. Notwithstanding the preceding sentence, the foregoing consents do not - apply to any act or omission which constitutes fraud in the inducement with respect to the global consent and agreement, the letter agreement dated July 24, 2003 between IGEN, BioVeris and the consenting parties, which is referred to in this proxy statement/prospectus as the MSD letter agreement, any MSD transaction document (as defined below) or the transactions contemplated by the global consent and agreement, the merger agreement and related transaction agreements, or - affect any consenting party's rights to enforce the global consent and agreement, the MSD letter agreement, any MSD transaction document to which it is a party or the merger agreement or any related transaction agreement to which it is a third party beneficiary, in each case, in accordance with its respective terms, and 98 In addition, the global consent and agreement also provides that, after the completion of the restructuring, all of the MSD agreements will remain in full force and effect and will be enforceable against each of the consenting parties and BioVeris in accordance with their respective terms. "MSD transaction documents" means the consent to the license agreement, the joinder to the ongoing litigation agreement, the covenants not to sue, the license agreement and the ongoing litigation agreement. ACKNOWLEDGMENT AND CONSENT Each consenting party acknowledged that, pursuant to the restructuring agreement and as part of the restructuring, all of IGEN's rights under and in respect of the MSD agreements will be assigned to, and all of IGEN's liabilities under and in respect of the MSD agreements will be assumed by, BioVeris upon the effectiveness of the restructuring, which is referred to in this proxy statement/prospectus as the MSD transfer. Each consenting party consented to the MSD transfer and, as of and with effect from the completion of the MSD transfer, unconditionally released IGEN from its obligations, duties and liabilities under the MSD agreements, whether arising before, at or after the MSD transfer. Each consenting party expressly consented to the assumption by BioVeris of all rights, obligations, duties and liabilities of IGEN under the MSD agreements and agreed to perform its obligations, duties and liabilities under the MSD agreements in accordance with their terms in favor of BioVeris. In this regard, MST consented to BioVeris's admission as a class A member, a class B member and a class C member of MSD, effective upon the completion of the MSD transfer, as successor to IGEN. Each of the events described in the previous sentence is conditioned upon the consummation of the MSD transfer, will occur simultaneously with the MSD transfer without any further action by any party, and, together with the MSD transfer, will have the effect of amending the MSD agreements. BioVeris, IGEN and each consenting party agreed that as of and with effect from the MSD transfer, each of the MSD agreements will cease to create or confer any rights or obligations on or as to IGEN, except for IGEN's confidentiality obligations under such agreements, and each of the MSD agreements will continue as an agreement among the parties to the MSD agreements (other than IGEN) and BioVeris on the same terms and conditions as those stated in such MSD agreement. BioVeris, IGEN, MSD and MST agreed to amend and restate each such MSD agreement to reflect such matters effective from the MSD transfer. Each consenting party agreed that, notwithstanding any provision of any MSD agreement to the contrary, such consenting party will not be entitled to any payment from IGEN as a result of or in connection with the transactions contemplated by the merger agreement or the MSD transfer, except as specifically provided in the letter agreement and except as provided in any stock option agreements between IGEN and any employee of MSD (including all stock option agreements with Mr. Jacob Wohlstadter granted to him in his capacity as a consultant to IGEN). As of and with effect from the completion of the MSD transfer, except for the rights of the license sub under the license agreement and the consent of MSD and MST to the license agreement, - BioVeris will own all right, title and interest in and to all intellectual property and other proprietary and confidential information or materials owned by IGEN as of the date of the global consent and agreement or benefits acquired by IGEN between the date of the global consent and agreement and immediately prior to the completion of the MSD transfer to which any consenting party has any direct or indirect rights or benefits (including patents, copyrights and trade secrets) pursuant to the MSD agreements, and - IGEN thereafter will hold no interest in MSD nor will it have possession of, or rights or access to, any proprietary or confidential information of any consenting party, and IGEN will not own or otherwise have rights or seek to own or otherwise have rights in any intellectual property or other proprietary information or materials which any consenting party owns or to which any consenting 99 party otherwise has any direct or indirect rights or benefits (including patents, copyrights and trade secrets) pursuant to the MSD agreements. NO CHANGE OF CONTROL BioVeris, IGEN and each consenting party each agreed that the execution and delivery of the merger agreement and related transaction agreements does not, and the consummation of the merger and related transactions will not, constitute a "change in control" as defined in the MSD joint venture agreement dated as of November 30, 1995 among MSD, MST and IGEN, which is referred to in this proxy statement/prospectus as the MSD joint venture agreement, or the employment agreement dated as of August 15, 2001 among MSD, IGEN, MST and Mr. Jacob Wohlstadter. LIMITATION ON CERTAIN CLAIMS Roche, on the one hand, and the consenting parties, on the other hand, each agreed not to, and not to permit their affiliates to encourage any other person to, assert any rights or pursue any actions or claims against the other or their respective affiliates or current or former directors, officers, members of the board of managers, members, managers, employees, consultants, advisors, attorneys, trustees or agents based on acts or omissions occurring prior to completion of the merger. This covenant, however, does not - prevent actions to enforce the merger agreement or any related transaction agreement, MSD transaction document, I/R agreement or BioVeris I/R agreement, - apply to acts or omissions that constitute fraud in the inducement with respect to the merger agreement or any related transaction agreement, MSD transaction document, I/R agreement or BioVeris I/R agreement, or - apply to actions permitted or required by the ongoing litigation agreement. MUTUAL RELEASE Roche, on the one hand, and each consenting party, on the other hand, release, as of immediately prior to completion of the merger, the other and its past, present and future affiliates and its and their respective successors, assigns, heirs, officers, directors, members of the board of managers, members, managers, employees, consultants and trustees from, and agree not to bring any action against the foregoing related to, all debts, demands, actions, causes of action, suits, accounts, covenants, contracts, agreements, torts, damages, claims, defenses, offsets, judgments, demands and liabilities whatsoever which have been or could have been asserted against the other person arising out of or relating to events or actions taken by such other person prior to the completion of the merger.

MSD LETTER AGREEMENT This is a summary of the material provisions of the MSD letter agreement. The MSD letter agreement is attached as Annex 7 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire MSD letter agreement carefully. 100 Simultaneously with the execution and delivery of the merger agreement, IGEN, BioVeris and the consenting parties entered into the MSD letter agreement, pursuant to which, among other things: - IGEN and MST agreed to extend the expiration of the term of the MSD joint venture agreement such that it will expire on the later of - November 30, 2003, or - the earlier of the completion of the merger or the termination of the merger agreement in accordance with its terms; and - BioVeris agreed to make to MSD a class C capital contribution in the amount of $37.5 million on the first business day following completion of the merger. However, in the event completion of the merger has not occurred prior to December 1, 2003, IGEN will provide continued funding to MSD to be paid monthly on the first day of each month commencing on December 1, 2003 in an amount per month equal to one-twelfth (1/12th) of the aggregate committed funding of IGEN under the approved 2003 budget pursuant to the MSD joint venture agreement, which is approximately $1.7 million per month, until the earlier to occur of completion of the merger or termination of the merger agreement in accordance with its terms. Such interim funding will reduce the amount of BioVeris's contribution following completion of the merger. In the event completion of the merger does not occur, MSD will not have any obligation to repay any amounts provided to MSD as interim funding (except to the extent IGEN is entitled to receive distributions on the class C interests pursuant to the MSD joint venture agreement). BIOVERIS PREFERRED STOCK PURCHASE AGREEMENT This is a summary of the material provisions of the letter agreement entered into by BioVeris and Mr. Samuel Wohlstadter. The BioVeris preferred stock purchase agreement is attached as Annex 8 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire BioVeris preferred stock purchase agreement carefully. At the request of the JVOC and as an accommodation to facilitate completion of the merger, Mr. Samuel Wohlstadter entered into the BioVeris preferred stock purchase agreement, pursuant to which he agreed to subscribe for a new series of preferred stock to be issued by BioVeris following its conversion into a corporation and completion of the merger for an aggregate cash amount of $7.5 million. The $7.5 million amount will be reduced by any reduction agreed to by the parties to the MSD letter agreement of the aggregate amount BioVeris is obligated to pay to MSD pursuant to the MSD letter agreement and will be payable at such time as BioVeris is obligated to pay MSD an aggregate amount in excess of $30 million. The BioVeris preferred stock will have a liquidation preference of $0.01 per share and will rank pari passu with BioVeris's existing and future preferred stock. Except for its liquidation preference, the economic characteristics of the BioVeris preferred stock will mirror, in all respects, BioVeris's economic interest in the class C interests in MSD received by BioVeris as a result of the capital contribution to MSD made by BioVeris with the proceeds for the sale of BioVeris preferred stock to Mr. Samuel Wohlstadter. BioVeris may redeem the BioVeris preferred stock for $0.01 per share at any time BioVeris is no longer entitled to receive distributions with respect to the class C interests described in the previous sentence pursuant to the MSD limited liability company agreement, and a proportionate part of the BioVeris preferred stock will be redeemed by BioVeris in connection with any redemption by MSD of the class C interests held by BioVeris in MSD described in the previous sentence. No distributions on the BioVeris preferred stock will be paid unless and until distributions are paid on such class C interests in accordance with the MSD limited liability company agreement, in which event distributions on the BioVeris preferred stock will be paid in the same manner and amount as such distributions on the class C interests. The shares of BioVeris preferred stock will be entitled in the aggregate to 1,000 votes on all matter on which holders of BioVeris common stock may vote. In addition, BioVeris may not consent to any adverse change to the terms of the class C interests described in this paragraph without the consent of the holders of the BioVeris preferred stock. For a more complete description of the BioVeris preferred stock, see "Description of BioVeris Capital Stock -- Preferred Stock -- Series B Preferred Stock." 101 RELEASE AND AGREEMENT This is a summary of the material provisions of the limited mutual release and agreement. The release and agreement is attached as Annex 9 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire release and agreement carefully. GENERAL Simultaneously with the execution of the merger agreement, Hyperion Catalysis International, Wellstat Biologics Corporation, Wellstat Therapeutics Corporation, Proteinix Corporation and Integrated Chemical Synthesizers, Inc., which are referred to in this proxy statement/prospectus as the related companies, entered into the release and agreement with BioVeris and IGEN, pursuant to which, the parties made certain agreements with respect to the relationship, agreements and understandings between IGEN and the related companies, which are referred to in this proxy statement/prospectus as the related company agreements. MUTUAL RELEASES IGEN, on the one hand, and each of the related companies, on the other hand, release, as of the time immediately prior to completion of the merger, the other and its past, present and future affiliates and its and their respective successors, predecessors, assigns, heirs, officers, directors, employees, consultants and trustees from all debts, demands, actions, causes of action, suits and liabilities whatsoever which have been or could have been asserted against the other person arising out of or relating to any relationship between IGEN or any of its affiliates at or prior to the effectiveness of the release, on the one hand, and any related company or any of its affiliates, on the other hand, or any related company agreement in existence at or prior to the effectiveness of the release. The release does not, however: - affect any person's right to enforce the release and agreement, the merger agreement or any related transaction agreement, any ongoing commercial agreement or any BioVeris I/R agreement; - relieve BioVeris or any related company from the obligation to pay any amounts accrued or due and payable under any related company agreement; - apply to any pursuit of any action against any person other than in connection with a released matter; - constitute a grant to IGEN of a license, any freedom to operate, or any covenant not to sue under any intellectual property owned by, licensed to, or otherwise held at the time of completion of the merger by any related company; or - constitute a grant to any related company of a license, any freedom to operate, or any covenant not to sue under any intellectual property owned by, licensed to, or otherwise held at the time of completion of the merger by IGEN, BioVeris or any of their subsidiaries. CERTAIN AGREEMENTS IGEN and each of the related companies agreed that as part of the restructuring, each related company agreement that is not in writing will be memorialized in writing and executed on behalf of each of the parties thereto. In addition, each of the related companies acknowledged that, pursuant to the restructuring agreement and as part of the restructuring, all of IGEN's rights and liabilities under and in respect of the related company agreements will be assigned to and assumed by BioVeris immediately prior to completion of the merger. Each of the related companies consented to this assignment and assumption and, as of the time immediately prior to completion of the merger, unconditionally released IGEN from all obligations, duties and liabilities under the related company agreements whether arising before, at or after the assignment or assumption. Each of the related companies agreed to perform its obligations, duties and liabilities under the related company agreements in favor of BioVeris, and BioVeris expressly agreed to assume and 102 perform IGEN's obligations, duties and liabilities under the related company agreements in favor of the related companies. Accordingly, BioVeris, IGEN, and each of the related companies agreed that with effect from the assignment and assumption each of the related company agreements will no longer create or confer any rights or obligations on or as to IGEN (or its affiliates (other than BioVeris or any of its subsidiaries)) but will continue among the parties thereto (other than IGEN) and BioVeris on the same terms and conditions as those stated in such related company agreement. BioVeris, IGEN and each of the related companies agreed to amend and restate each such related company agreement to reflect such novation. 103 COMMERCIAL AGREEMENTS LICENSE AGREEMENT This is a summary of the material provisions of the license agreement. The license agreement is attached as Annex 10 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire license agreement carefully. GENERAL Simultaneously with the execution of the merger agreement, IGEN entered into the license agreement with the license sub, a wholly-owned subsidiary of IGEN that will become an indirect subsidiary of Roche upon completion of the merger. As part of the restructuring prior to the completion of the merger, IGEN's rights, title and interest under the license agreement (other than any right, title and interest of the license sub) will be transferred to BioVeris, so that, after the transfer, the license agreement will be between BioVeris and the license sub. BioVeris will then be bound by all the obligations, and BioVeris will be entitled to all the rights, of IGEN under the license agreement. LICENSES IGEN and its affiliates will grant to the license sub simultaneously with the completion of the merger, a worldwide, non-exclusive, royalty-free license under patents and technology that relate to detection methods and systems that employ ECL technology, but specifically excluding technology related to gene amplification or compounds composed of or capable of binding with nucleotides and analogs thereof. The license may be used only in the field described below to develop, manufacture, reproduce, modify, use, sell and otherwise commercially exploit the products specified below. The license sub may only sublicense these rights to its affiliates. Subject to certain requirements and conditions, the license sub may grant to its distributors, contract manufacturers, toll manufacturers, component suppliers, leasing agents and other third parties engaged by the license sub to assist in the commercialization of the licensed patents and technology immunity from suit under the licensed patents and technology in the licensed field but solely for the benefit of the license sub. Furthermore, such authorized third parties shall have the rights to use the licensed patents and technology in the licensed field as may be necessary to allow such third parties to assist the license sub and its affiliate sublicensees in the commercialization of the licensed patents and technology. The field in which this license may be used is the analysis of specimens taken from a human body for the purpose of testing for a physiological or pathological state, a congenital abnormality, safety and compatibility of a treatment or to monitor therapeutic measures, but the field specifically excludes analysis for: - life science research or development; - patient self testing use; - drug discovery or drug development, including clinical research or determinations in or for clinical trials or in the regulatory approval process for a drug or therapy; and - veterinary, food, water or environmental testing or use. The products for which the license may be used, which are referred to in this proxy statement/prospectus as licensed products, are limited to: - diagnostic instruments that use or are based on the licensed ECL technology solely for use with one of the immunoassays described below, if the instruments satisfy each of 10 criteria relating primarily to size, capacity and functionality, and services and spare parts related to such instruments; and 104 - immunoassay methods for human in vitro diagnostic testing consisting of or based on the licensed ECL technology and (1) that have obtained approvals from, or been registered with, applicable governmental agencies, if required, or been manufactured in accordance with the regulations of applicable governmental agencies, (2) that are manufactured and sold solely in reagent packs and (3) in which the detection or quantification of an analyte is determined by the binding of an antibody or antibody fragment, but excluding assays for drugs of abuse, therapeutic drug monitoring (with two specific exceptions), detection of exposure to chemical agents or weapons, detection of certain biological agents, toxins or weapons or certain allergies, assays that incorporate nucleic acids or utilize or detect nucleic acid or use compounds that are composed of, or capable of binding with, nucleotides or analogs thereof and assays that include the use of disposable electrodes or a patterned surface used for one or more measurements. In addition to the license described above, IGEN and its affiliates will grant to the license sub simultaneously with the completion of the merger, a worldwide, non-exclusive, royalty-free license under the licensed ECL technology to provide licensed products (which may include assays not yet approved by or registered with the applicable governmental agencies nor manufactured in accordance with the regulations of applicable governmental agencies) to certain users for specific limited purposes pertaining to the development or evaluation testing of licensed products or to obtain or extend regulatory approval for such licensed products. Roche Diagnostics' current Elecsys 1010, Elecsys 2010 and the ECL Module of the E-170 instruments, as well as listed immunoassays that meet specified criteria, are deemed to be products that are permitted under this license agreement. The license sub has agreed not to develop, use, manufacture or sell ECL assays that are packaged specifically for, and function only for use on, instruments manufactured or sold by BioVeris or its licensees or resellers. The license sub must assure that its affiliate sublicensees and third-party commercializing agents assign to the license sub all intellectual property rights to ECL technology that they may develop or create. PAYMENTS There are no license fees, royalties or milestones payable to IGEN (or, after the restructuring, BioVeris) under the license agreement. However, the license sub may continue to sell licensed products for out-of-field uses of such ECL instrument until BioVeris notifies the license sub in writing that it is prohibited from making any further such sales. In addition, the license sub will pay BioVeris 65% of all undisputed revenues earned through out-of-field sales of licensed products for the prior year. TERM The license agreement takes effect on the completion of the merger. The license agreement lasts until the expiration of all licensed patents and the complete loss of confidential and proprietary status of all licensed ECL technology. The license sub may terminate the license if BioVeris materially breaches the agreement. Subject to certain limitations, BioVeris can terminate the license agreement only if the license sub or any of its affiliates sells, places or otherwise commercializes instruments or assays that use ECL technology and that fail to qualify as licensed products. In advance of any sale, the license sub may request a determination from BioVeris whether a particular instrument or assay is within the scope of the licensed product definitions. Disputes as to whether a product qualifies as a licensed product will be resolved by arbitration in accordance with the license agreement. 105 INDEMNIFICATION The license sub indemnifies BioVeris against all claims, damages, losses, costs and expenses arising from the license sub's sale of licensed products. The license sub is also jointly and severally responsible for any breaches of the license agreement by its affiliate sublicensees. ASSIGNMENT Neither party may assign its rights under the license agreement without the consent of the other party, except that no such consent is required with respect to an assignment of any or all of its rights and obligations to an affiliate or of all (but not less than all) of its rights and obligations under the license agreement to an acquiror of all or substantially all of the assets or business of the assigning party related to such party's use of ECL technology. IGEN is explicitly permitted to assign its rights to BioVeris and will assign its rights to BioVeris as part of the restructuring. CONSENT MSD and MST signed a separate consent to the licenses granted to the license sub in the license agreement under which they consented to and joined in such licenses and waived any right to restrict or limit the license sub's and its affiliates' exercise of the licenses granted in the license agreement. IMPROVEMENTS LICENSE AGREEMENT This is a summary of the material provisions of the improvements license agreement and other important information relating to the improvements license agreement. The improvements license agreement is attached as Annex 11 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire improvements license agreement carefully. GENERAL Simultaneously with the execution of the merger agreement, IGEN entered into the improvements license agreement with Roche Diagnostics. As part of the restructuring prior to the completion of the merger, IGEN's rights, title and interest under the improvements license agreement will be transferred to BioVeris, so that, after the transfer, the improvements license agreement will be between Roche Diagnostics and BioVeris. BioVeris will then be bound by all the obligations, and BioVeris will be entitled to all the rights, of IGEN under the improvements license agreement. Roche has advised BioVeris that Applied Biosystems has notified Roche that one or more of the PCR licenses granted by certain Roche affiliates to BioVeris, including potentially the PCR license granted under the improvements license agreement, may infringe exclusive rights to PCR technology held by, or other contract rights of, Applied Biosystems. Applied Biosystems has commenced litigation and arbitration against Roche regarding their respective rights relating to PCR technology. Certain Roche affiliates have made certain representations and provided certain warranties in the improvements license agreement on their right to grant the licenses that have been granted to BioVeris, including representations and warranties that: the rights and licenses granted under the improvements license agreement and the performance by Roche Diagnostics of its obligations under the improvements license agreement will not conflict with any agreement, contract or other arrangement to which it is a party or by which it is bound; Roche Diagnostics has title to or license rights sufficient to grant such license rights granted under the improvements license agreement to BioVeris and its affiliates; and Roche Diagnostics has not licensed or otherwise disposed of such licensed intellectual property rights in any manner that limits BioVeris's or its affiliates' exploitation of the licenses granted by Roche Diagnostics under the improvements license agreement. Roche has advised IGEN that it believes that Applied Biosystems' allegations are without merit and intends to contest them vigorously. There are no assurances that BioVeris will not be named as a defendant in either of those actions or that Roche will prevail in the litigation and arbitration, or that the terms of any resolution or settlement of these proceedings will not be unfavorable to BioVeris. The results of these legal proceedings may limit, preclude or interfere with BioVeris's ability to exploit certain PCR 106 technology licensed under the improvements license agreement. See "Risk Factors -- Risks Relating to BioVeris and Its Business -- Because BioVeris intends to develop products that are based on patents and technology that it has licensed from others, the owners of those patents and technology might claim that products developed or sold by BioVeris violate those licenses. Additionally, a third party might object to a license that BioVeris holds or to the scope of the license granted to BioVeris." LICENSES Roche Diagnostics and its affiliates will grant to BioVeris, simultaneously with the completion of the merger, an irrevocable, worldwide, non-exclusive, fully-paid, royalty-free, perpetual license under certain patents covering and technologies based on - Roche Diagnostics' ECL instruments and all aspects of ECL assays developed prior to the completion of the merger, - certain PCR technology, or - all aspects of ECL technology and robotics that, prior to the completion of the merger, Roche Diagnostics or any of its affiliates used or developed to be used in performing ECL testing (other than specific antibodies, antigens and reagents). The license may be used without a field restriction (except as set forth in the next sentence) to develop, make, reproduce, modify, use, sell and otherwise commercially exploit any product or service based on ECL technology. In addition, BioVeris is licensed to use certain intellectual property rights of Hitachi High Technology Corporation and its affiliates only outside the field defined in the improvements license agreement to develop, make, reproduce, modify, use, sell and otherwise commercially exploit any product or service based on ECL technology. Subject to an exception, the field in the improvements license agreement is the same as the field in the license agreement. BioVeris may sublicense rights under both of these licenses to affiliates and third parties. As of the completion of the merger, the improvements license agreement will supersede the 1992 License Agreement and the licenses granted by Roche Diagnostics pursuant to the final order of judgment. The license does not permit BioVeris to develop, use, manufacture, sell or otherwise commercialize instruments based on ECL technology that meet certain specifications and use specific intellectual property, which are referred to in this proxy statement/prospectus as copycat instruments, in the field. In addition, the license does not permit BioVeris to develop, use, manufacture or sell ECL assays that contain labelling that make them useable on ECL instruments manufactured, sold or placed by Roche Diagnostics or its licensees or resellers, or on copycat instruments, in the field. BioVeris must assure that its sublicensees and third-party commercializing agents assign to BioVeris all intellectual property rights to patents or technology licensed by Roche Diagnostics or Hitachi under the improvements license agreement that such sublicensees or third-parties may develop or create. PAYMENTS There are no license fees, royalties or milestones payable to Roche Diagnostics under the improvements license agreement. BioVeris may continue to sell copycat instruments or products such as assays used on copycat instruments in the field until the license sub notifies BioVeris in writing that it is prohibited from making any further such sales. In addition, BioVeris will pay to Roche Diagnostics 65% of all undisputed revenues earned through its in-field sales of such instruments and products for the prior year. TERM The improvements license agreement takes effect on the completion of the merger. The improvements license agreement lasts until the expiration of all licensed patents and the complete loss of confidential and 107 proprietary status of all licensed Roche Diagnostics technology. The improvements license agreement cannot be terminated by Roche Diagnostics for any breach by BioVeris. INDEMNIFICATION BioVeris indemnifies Roche Diagnostics against all claims, damages, losses, costs and expenses arising from BioVeris's sale of licensed products. BioVeris is also jointly and severally responsible for any breaches by its sublicensees. ASSIGNMENT Neither party may assign its rights under the improvements license agreement without the consent of the other party, except that no such consent is required with respect to an assignment of any or all of its rights and obligations to an affiliate or of all (but not less than all) of its rights and obligations under the improvements license agreement to an acquiror of all or substantially all of the assets or business of the assigning party related to such party's use of ECL technology. IGEN is explicitly permitted to assign its rights to BioVeris and will assign its rights to BioVeris as part of the restructuring. COVENANTS NOT TO SUE This is a summary of the material provisions of the covenants not to sue. The covenants not to sue is attached as Annex 12 to this proxy statement/prospectus and is incorporated herein by reference. You should read the entire covenants not to sue carefully. GENERAL Simultaneously with the execution of the merger agreement, BioVeris entered into the covenants not to sue with Roche, Roche Diagnostics, MSD, MST and the license sub. Term. The covenants not to sue takes effect on the completion of the merger. If the merger agreement is terminated pursuant to its terms prior to the completion of the merger, the covenants not to sue automatically and simultaneously terminates. Assignment. No party may assign its rights under the covenants not to sue without the consent of all of the parties to the covenants not to sue, except that such consent is not required with respect to an assignment of any or all of a party's rights and obligations to an affiliate of the assigning party or of all (but not less than all) of its rights and obligations under the covenants not to sue to an acquiror of all or substantially all of the assets or business of the assigning party related to such party's use of ECL technology. COVENANT FROM ROCHE AND RELATED PARTIES Covenant. Each of Roche and Roche Diagnostics and, after the closing of the merger, the license sub, on behalf of itself and its affiliates, agreed that it will not directly or indirectly assert or pursue (or induce or cooperate with any third party to assert or pursue) any claim against BioVeris, MSD or MST, or any of their respective affiliates, sublicensees and other related parties, that the manufacture, use, sale, offer for sale, importation or exploitation of any product, the authorization of others to do any of the foregoing, the provision of any service, the practice of any method or the promulgation of any specification that, in each case, is conducted with respect to a product or service that uses ECL technology and is conducted after the completion of the merger infringes certain ECL patents that are filed or acquired after the completion of the merger. In order for BioVeris's, MSD's or MST's affiliates, sublicensees or other related parties to receive the benefit of the covenant not to sue, they must be bound by the covenant in favor of the Roche entities and the license sub, as described below. The covenant does not block actions or claims based on violations of the ongoing commercial agreements. 108 Any sale, transfer or other disposition of a Roche patent from which BioVeris receives protection under this covenant or of an intellectual property right licensed to BioVeris, as the assignee of IGEN's rights, under the improvements license agreement is subject to this covenant. Termination. The covenant shielding BioVeris, MSD and MST terminates on the last date on which a Roche entity may assert or bring any legal or equitable claim against any of BioVeris, MSD and MST, or any of their affiliates or related parties, under any of the Roche patents from which BioVeris receives protection under this covenant. COVENANT FROM BIOVERIS, MSD AND MST AND RELATED PARTIES Covenant. Each of MSD, MST and BioVeris, on behalf of itself and its affiliates, agreed that it will not directly or indirectly assert or pursue (or induce or cooperate with any third party to assert or pursue) any claim against Roche, Roche Diagnostics, the license sub, or any of their affiliates and other related parties, that the manufacture, use, sale, offer for sale, importation or exploitation of any product, the authorization of others to do any of the foregoing, the provision of any service, the practice of any method or the promulgation of any specification that, in each case, is conducted with respect to a licensed product or service in the field, as defined in the license agreement, and is conducted after the completion of the merger infringes certain ECL patents that are filed or acquired after the completion of the merger. In order for any of Roche's, Roche Diagnostics' or the license sub's affiliates or other related parties to receive the benefit of the covenant not to sue, it must be bound by the covenant in favor of BioVeris, MSD and MST, as described above. The covenant does not block actions or claims based on violations of the ongoing commercial agreements. Any sale, transfer or other disposition of a BioVeris, MSD or MST patent from which Roche receives protection under this covenant or of an intellectual property right licensed to the license sub under the license agreement is subject to this covenant. If the license agreement is terminated or expires, nothing in the covenants not to sue prevents BioVeris, MSD, MST or their respective affiliates from directly or indirectly asserting or pursuing any claim against the Roche entities for activities after the date of such termination or expiration that would infringe any of the patents under which the Roche entities and the license sub would otherwise be protected under this covenant. The covenant not to sue does not shield the Roche entities and the license sub from any future claims brought by MSD or MST against Roche, Roche Diagnostics, the license sub, their affiliates or related parties that their activities conducted after the completion of the merger in conjunction with ECL technology that uses or infringes any intellectual property right of MSD or MST relating to carbon electrodes, disposable electrodes or multi-array assays defined in the license agreement. Termination. The covenant shielding the Roche entities terminates on the earlier of (i) the last date on which BioVeris, MSD or MST may assert or bring any legal or equitable claim against any of the Roche entities, or their affiliates or related parties, under any of BioVeris's patents from which they receive protection, or (ii) the date that the license agreement is terminated. PCR LICENSE AGREEMENTS This is a summary of the material provisions of the PCR license agreements and other important information relating to the PCR license agreements. The PCR license agreements are attached as Annex 13 and Annex 14 to this proxy statement/prospectus and are incorporated herein by reference. You should read the entire PCR license agreements carefully. 109 GENERAL Simultaneously with the execution of the merger agreement, BioVeris entered into the PCR license agreements with F. Hoffmann-La Roche Ltd, Roche Diagnostics and Roche Molecular Systems, Inc. One agreement grants BioVeris rights to make, import, use and sell certain PCR products within specified fields, while the other agreement grants BioVeris rights to perform certain PCR services within specified fields. Roche has advised BioVeris that Applied Biosystems has notified Roche that one or more of the PCR licenses granted by certain Roche affiliates to BioVeris, including potentially the PCR licenses granted under one or more of the PCR license agreements, may infringe exclusive rights to PCR technology held by, or other contract rights of, Applied Biosystems. Applied Biosystems has commenced litigation and arbitration against Roche regarding their respective rights relating to PCR technology. Certain Roche affiliates have made certain representations and provided certain warranties in the PCR license agreements on their right to grant the licenses that have been granted to BioVeris, including representations and warranties that: certain Roche affiliates have the full power and right to grant to BioVeris and its affiliates the licenses granted under the PCR license agreements and the execution by certain Roche affiliates of the PCR license agreements will not constitute a breach or default under any contract, instrument or agreement to which such Roche affiliates or any of their affiliates are a party or by which such Roche affiliates or any of their affiliates are bound. Roche has advised IGEN that it believes that Applied Biosystems' allegations are without merit and intends to contest them vigorously. There are no assurances that BioVeris will not be named as a defendant in either of those actions or that Roche will prevail in the litigation and arbitration, or that the terms of any resolution or settlement of these proceedings will not be unfavorable to BioVeris. The results of these legal proceedings may limit, preclude or interfere with BioVeris's ability to exploit certain PCR technology licensed under the PCR license agreements. See "Risk Factors -- Risks Relating to BioVeris and Its Business -- Because BioVeris intends to develop products that are based on patents and technology that it has licensed from others, the owners of those patents and technology might claim that products developed or sold by BioVeris violate those licenses. Additionally, a third party might object to a license that BioVeris holds or to the scope of the license granted to BioVeris." LICENSES Effective simultaneously with the completion of the merger and for a license fee of $50 million plus royalties as specified in the PCR license agreements, the Roche entities will grant to BioVeris and its affiliates, worldwide, non-exclusive licenses under patents that cover PCR inventions for - the performance of sample collection, preparation, transport and/or isolation of nucleic acid sequences using PCR, - the amplification of nucleic acid sequences using PCR, - the detection of nucleic acid sequences using PCR, - the synthesis, purification, labeling and/or immobilization of nucleic acid probes used in PCR and/or - the control of contamination. The licensed patents do not include: - any rights to inventions for biological and chemical target information, such as nucleic acid sequences, the making, selling or using of which would infringe a claim of a patent or patent application owned by the Roche entities and available for license to BioVeris and that is not included in the patent list attached to each agreement at the completion of the merger; or - any rights to inventions for instruments and/or automation of PCR related inventions. 110 BioVeris and its affiliates may make, import, use, sell and offer to sell certain products (excluding stand-alone enzyme reagents and certain instruments), and authorize end users to perform diagnostic services using such products, in the fields of animal diagnostics, paternity determination, transplant typing, in vitro human diagnostics, plasma testing and DNA molecule manufacturing. BioVeris and its affiliates may also use PCR technology internally for the research, development, improvement, quality control and quality assurance of such products. BioVeris and its affiliates may use the license internally to determine the nucleic acid sequences for screening blood and blood products or for quality control purposes in the production of blood products, but may not use the test results for diagnostic purposes or for the treatment of an individual. BioVeris may also perform in vitro human and animal diagnostic testing using PCR technology. For purposes of these agreements, MSD will be considered, regardless of BioVeris's relationship with MSD, an affiliate of BioVeris that may operate under the licenses granted by the Roche entities under these agreements. Neither BioVeris nor its affiliates may sublicense BioVeris's rights under the licenses, except that BioVeris may permit its end users to use the licensed products to perform in vitro human and animal diagnostic testing procedures, may permit its research collaborators to practice PCR to do applied research, development, improvement, quality control or quality assurance for licensed products and may market in vitro human and animal diagnostic testing procedures performed by other licensed laboratories. The agreements specifically do not permit BioVeris to make or sell Roche's patented enzymes (stand-alone) for use with BioVeris's products. LICENSE NEGOTIATIONS At the request of the Roche entities, BioVeris will enter into good faith negotiations to grant the Roche entities a worldwide, non-exclusive, royalty-bearing, field-limited license with respect to BioVeris's patent rights that claim PCR inventions. At BioVeris's request, Roche will enter into good faith negotiations with BioVeris with respect to a license under the Roche PCR patents for fields other than the licensed fields if Roche has the right to grant such licenses in such other fields and makes it a practice to license such other fields to third parties. PAYMENTS BioVeris will pay to the Roche entities a license fee of $50 million no later than two business days after the completion of the merger. BioVeris will also pay royalties on sales of the licensed products in the licensed fields and on any instrument, accessory, device or system sold for use with the licensed products in the licensed fields at royalty rates ranging from 3% to 20% of net sales, depending on the field, the year, the country of sale and the patents covering such products. BioVeris will pay royalties of $16 or $25 for every PCR plasma test BioVeris performs or has a laboratory perform. BioVeris will pay royalties ranging from 5% to 20% of net service revenue that BioVeris receives for diagnostic testing procedures that BioVeris performs using PCR technology, including any performed by IGEN prior to execution of the PCR services license agreement. MOST FAVORED LICENSEE If, after the completion of the merger, Roche grants a license to a third party in the fields of human or animal diagnostic services or products and diagnostic processes using PCR for human diagnostic purposes, under substantially equivalent terms and conditions as the relevant PCR license agreement, but under substantially equivalent terms and conditions as the PCR license agreements, at more favorable royalty rates, BioVeris may elect to receive such more favorable rates. In considering whether the terms and conditions of the license granted to the third party is substantially equivalent to the PCR license agreements, the termination provisions of the PCR license agreements will not be considered. If BioVeris elects to receive the more favorable royalty rates offered to the third party, BioVeris must also accept all the terms and conditions offered to the third party, except that the termination provisions of the PCR license agreements will not be changed. 111 BioVeris's right to receive the more favorable rates will not apply if the Roche entities receive substantial technology or intellectual property rights as consideration for granting such a license to the third party. ROYALTY REDUCTIONS DUE TO INFRINGEMENT If, in any country, an unlicensed third party is selling products equivalent to one of BioVeris's licensed diagnostic kits, and those sales represent at least 15% of total sales of competitive products in such country, BioVeris may reduce by 50% the royalties that BioVeris pays to Roche in that country if Roche does not license that third party or sue that third party for infringement within a certain period of time. If the unlicensed third party's sales represent at least 30% of the competitive market, the royalties that BioVeris pays to Roche are eliminated in that country if Roche does not license that third party or sue that third party for infringement within a certain period of time. If and when Roche then licenses that third party or sues that third party for infringement, the royalty rates return to their original levels. An enforcement proceeding pursued against an infringer for sales in one major territory will satisfy Roche's obligation to pursue enforcement against such infringing products in all countries. If no substantial infringement exists in any such major territory, then a suit in any other country where such substantial infringement exists will satisfy Roche's obligation to bring an enforcement action. For purposes of the PCR license agreements, the term "major territory" shall mean any of the United States, Great Britain, Germany, France, Italy, the Netherlands and Japan. TERM The PCR license agreements take effect on the completion of the merger and expire upon the expiration of the last valid claim of the licensed patents. The PCR product license agreement can be terminated by Roche if BioVeris does not pay the $50 million license fee. Each PCR license agreement can be terminated by Roche if BioVeris does not pay undisputed royalties owed under the agreement within a specified time period or if BioVeris does not pay disputed royalties owed under the agreement within 30 days after a final arbitrated resolution of such dispute. Each PCR license agreement can be terminated by BioVeris on written notice to Roche. Otherwise, the PCR licenses are perpetual and irrevocable. INDEMNIFICATION BioVeris will indemnify the Roche entities against all claims, damages, losses, costs and expenses arising from sales by BioVeris or its affiliates of the licensed products and services. BioVeris is also jointly and severally responsible for any breaches by its affiliates. ASSIGNMENT Neither the Roche entities nor BioVeris may assign its rights or obligations under the PCR license agreements without the prior consent of the other, except that such consent is not required with respect to an assignment of any or all of a party's rights and obligations under a PCR license agreement to an affiliate of such assigning party or of all (but not less than all) of its rights and obligations under a PCR license agreement to an acquiror of all or substantially all of the assets or business of the assigning party related to such party's use of the licensed patents. INTERSECTION WITH IMPROVEMENTS LICENSE AGREEMENT If there is an inconsistency between one of the PCR license agreements and the improvements license agreement, the improvements license agreement will control. For example, if BioVeris is licensed under the royalty-free improvements license agreement to make, use or sell a product or service, and BioVeris does not need a license under the PCR license agreements to make, use or sell such product or service, then BioVeris does not have to pay a royalty to the Roche entities to make, use or sell such product or service. 112 CAPITALIZATION The following table sets forth BioVeris's historical and pro forma capitalization as of September 30, 2003 on an actual basis and on a pro forma basis to give effect to the merger and related transactions.

(2,500) -------- Cash on-hand to be transferred from IGEN to BioVeris upon merger.................................................... $205,000 -------- (2) Assumes payment of $50 million to certain affiliates of Roche for a worldwide, non-exclusive license under patents that cover certain PCR inventions. BioVeris will also pay royalties based on the sales of licensed products by BioVeris and on any instrument, accessory, device or system sold for use with the licensed products, the revenue that BioVeris receives for diagnostic testing procedures that BioVeris performs using PCR technology and the number of PCR plasma tests BioVeris performs or has a laboratory perform. For a more complete description of the PCR license agreements, see "Commercial Agreements -- PCR License Agreements." BioVeris will amortize the license fee over an estimated useful life of 10 years based upon a consideration of the range of patent lives and the weighted average remaining life of the most important underlying patents as well as a consideration of technological obsolescence and product life cycles. BioVeris does not currently sell, or have under development, any product based on the PCR technology being licensed from Roche. (3) Assumes payment of the capital contribution of $37.5 million to MSD. After the restructuring, and subject to MSD's and MST's right to buy BioVeris's interests in MSD, BioVeris will hold a 31% voting interest in MSD and after the capital contribution of $37.5 million to MSD, will be entitled to a preferred return on $115.1 million. (4) Assumes purchase by Mr. Samuel Wohlstadter of $7.5 million of shares of series B preferred stock that economically mirror the class C interest in MSD to be held by BioVeris to be issued by BioVeris. (5) Pursuant to the tax allocation agreement among Roche, the merger sub, IGEN and BioVeris, BioVeris may be required to make a payment to IGEN of up to $20 million within ten days of receiving notice from Roche. The amount of the payment will depend on the average of the high and the low trading prices of BioVeris common stock on the first day of trading after the completion of the merger. A payment will be due if such average is at least approximately $11.41 per share and the maximum payment will be due if such average exceeds approximately $13.28, in each case based on the assumption that BioVeris will have $205 million in cash and cash equivalents immediately after completion of the merger and prior to making any payments due pursuant to the related transaction agreements, the ongoing commercial agreements or the MSD letter agreement. If paid in full, the amount of cash, on a pro forma basis at September 30, 2003 would be $105 million. (6) In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities," or FIN 46. FIN 46 provides guidance on variable interest entities such as the MSD joint venture and the framework through which an enterprise assesses consolidation of a variable interest entity. BioVeris will adopt FIN 46 as of January 1, 2004 and has determined that MSD qualifies as a variable interest entity based upon the following rationale: - BioVeris has provided substantially all of MSD's funding since inception through capital contributions consisting of class B and C non-voting equity interests. Such funding is not considered "at risk" as the investments do not participate significantly in the profits of MSD given their stated return rates. As such the "at risk" equity of MSD is insufficient to absorb MSD's expected future losses. - BioVeris holds 31% of the voting rights in MSD while providing 100% of MSD's funding, and BioVeris is thereby considered to be involved in all of MSD's activities as defined under FIN 46. 115 As the merger and related transactions do not change the design of or ownership interests in MSD in such a manner that could affect the status of MSD as a variable interest entity or BioVeris as the primary beneficiary, BioVeris does not believe they are deemed to be events that would require reassessment of BioVeris's previous conclusion that MSD qualifies as a variable interest entity under FIN 46. Accordingly, beginning January 1, 2004 and continuing subsequent to the completion of the merger and related transactions, BioVeris will consolidate the financial results of MSD. Under the transition guidance of FIN 46, because MSD was created before February 1, 2003, BioVeris will measure the assets, liabilities and noncontrolling interests of MSD as of January 1, 2004 for purposes of the initial consolidation. The amounts of the assets, liabilities and noncontrolling interests will be reflective of their respective carrying amounts had FIN 46 been effective when BioVeris first met the conditions to be the primary beneficiary of MSD upon MSD's inception in 1995. Such carrying amounts are expected to equal MSD's recorded values, which as of September 30, 2003, were approximately $17.0 million, $1.8 million and $10,000, respectively. As BioVeris has historically recorded and will continue to record approximately 100% of MSD's losses, it is anticipated that upon implementation of FIN 46, the consolidated net assets of MSD will approximate the book value of BioVeris's investment in joint venture. As such, consolidation accounting will require certain reclassifications within BioVeris's consolidated financial statements, but it is not expected to materially effect its financial position or net loss. The required balance sheet reclassifications will reclassify the amounts formerly recorded on a "net" basis as investment in joint venture to be reflected on a "gross" basis primarily as cash, accounts receivable, inventory, fixed assets, accounts payable and accrued expenses. The required statement of operations reclassifications will reclassify the amounts formerly recorded on a "net" basis as equity in loss of joint venture to be reflected on a "gross" basis primarily as revenue, product costs, research and development expenses and selling, general and administrative expenses. Historical financial information of MSD is summarized in Note 4 of BioVeris's consolidated financial statements and the audited MSD financial statements are included in the March 31, 2003 IGEN Form 10-K and incorporated by reference into the registration statement of which this proxy statement/prospectus is a part. (7) Reflects the reclassification of net investment by IGEN to common stock and additional paid-in capital upon distribution of 26,728,705 shares of BioVeris common stock. (8) BioVeris's net loss is expected to increase in the period in which the merger is completed as a result of BioVeris's recognition of an allocated one-time noncash compensation charge associated with the cancelation of IGEN stock options and the payment of the merger consideration for each share covered by IGEN stock options in connection with the merger. Upon completion of the merger, depending on the average first day trading price of BioVeris common stock, BioVeris will record a compensation charge for each IGEN stock option. BioVeris cannot predict what the average first day trading price of its common stock will be, however the table set forth below provides a range of hypothetical average first day trading prices for BioVeris common stock and the projected compensation charge if such price is the actual average first day trading price. The hypothetical average first day trading prices for BioVeris common stock have been provided for illustrative purposes only and are not intended to forecast or be indicative of the possible future performance of BioVeris common stock and BioVeris cannot provide any assurance that the average first day trading price of its common stock will be equal to any of the prices in the table set forth below. The table below includes the approximate compensation charge attributable to employee and nonemployee stock options based on these hypothetical average first day trading prices for BioVeris common stock. 116 APPROXIMATE HYPOTHETICAL AVERAGE FIRST DAY PROJECTED NONCASH TRADING PRICE OF COMPENSATION BIOVERIS COMMON STOCK CHARGE ------------------------------ ----------------- $0.00....................................................... $ 8,200,000 $5.00....................................................... 9,600,000 $10.00...................................................... 11,000,000 $11.75...................................................... 11,500,000 $12.00...................................................... 43,100,000 $15.00...................................................... 46,300,000 In calculating the projected compensation charge associated with the merger and related transactions, BioVeris applied the guidance of FIN 44 for employee stock options and SFAS 123 for nonemployee stock options. Under FIN 44, an assumption must be made as to the final closing price of IGEN common stock immediately prior to the merger. For this purpose, a final closing price of $59.00 per share has been assumed. In the merger, IGEN stockholders will be entitled to receive for each share of IGEN common stock they hold $47.25 in cash, without interest, and one share of BioVeris common stock, which yields an assumed, pre-spinoff value of BioVeris of $11.75 ($59.00 less $47.25). Under FIN 44 guidance, if the average first day trading price of BioVeris (post-spinoff value) exceeds $11.75, both vested and unvested employee stock options at the merger date are included in calculating the compensation charge. Alternatively, if the average first day trading price of BioVeris is less than or equal to $11.75, only the unvested employee stock options that have been accelerated are included in calculating the compensation charge. Under SFAS 123 guidance, compensation charge is calculated based upon the incremental fair value for the nonemployee stock options resulting from the merger. 117 SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA You should read the following selected historical consolidated financial data of BioVeris in conjunction with BioVeris's consolidated financial statements and notes and the other information contained in or incorporated by reference into this proxy statement/prospectus.

OVERVIEW BioVeris develops, manufactures and markets its M-SERIES(R) family of products, which can serve as a platform for diagnostic systems to be used for the detection and measurement of biological or chemical substances. BioVeris incorporates its technologies into its instrument systems, tests and reagents, which are the biological and chemical components used to perform such tests. Using the M-SERIES platform, BioVeris intends to integrate technologies and products to develop small, expandable and modular systems that can perform a wide variety of immunodiagnostic and nucleic acid tests. BioVeris's products are designed to be sold in the worldwide diagnostics markets, including: - Clinical diagnostics. The clinical diagnostics market includes the testing of patient samples to measure the presence of disease and monitor medical conditions. BioVeris is developing products to be used in the clinical diagnostics market and believes that its products are best suited for the immunodiagnostic and nucleic acid testing market segments of the clinical testing market. The immunodiagnostic and nucleic acid testing market segment sizes are estimated to be $6 billion and $1.5 billion, respectively. - Non-clinical diagnostics for the biodefense, life science and industrial markets. The non-clinical diagnostics market includes biodefense products for the detection of bacteria, viruses and toxins that may pose a military or public health threat; life science testing for drug discovery and development that is performed by pharmaceutical and biotechnology companies; and industrial testing for the detection of foodborne and waterborne disease causing pathogens. The life science market size is estimated to be $2.5 billion. BioVeris believes that the emergence of simple, more accurate and cost-effective clinical diagnostic products is shifting the site of clinical diagnostic testing from clinical reference laboratories and central hospital laboratories to decentralized patient care centers, such as physicians' offices, ambulatory clinics, hospital emergency rooms, surgical and intensive care units, hospital satellite laboratories and nurses' stations, which are collectively referred to in this proxy statement/prospectus as clinical point-of-care sites. BioVeris's own product development efforts will be focused on M-SERIES instruments and tests for the clinical diagnostics market, particularly for point-of-care sites. BioVeris will seek to develop, market and sell products for the clinical point-of-care market segment through a combination of direct efforts and collaborative arrangements. BioVeris also intends to pursue opportunities in the clinical reference laboratory and central hospital laboratory market segments through collaborative arrangements. The M1-M clinical analyzer is the first clinical diagnostic system being developed by BioVeris and builds on the M-SERIES instruments currently being sold by IGEN in the biodefense and life science markets. BioVeris's initial commercial focus for the M1-M will be to provide cardiac assays that test for heart attack and congestive heart failure. BioVeris is developing the cardiac assays using, among other things, improvements licensed from an affiliate of Roche. BioVeris believes that these improvements will reduce product development timelines. BioVeris also believes that the M1-M clinical analyzer will provide results to a physician rapidly with the same levels of sensitivity, accuracy or consistency as a large instrument in a clinical reference laboratory or in a central laboratory, thereby permitting the physician to make a more timely decision regarding the patient's course of treatment. BioVeris will seek approval from the FDA for the M1-M clinical analyzer and other in vitro diagnostics products at the appropriate stage of their product development. BioVeris's M-SERIES instruments are already being used in biodefense programs for homeland security, including by the Department of Defense, or DOD. BioVeris believes there will be an increasing 120 opportunity to sell its products for biodefense tools by governmental and military organizations around the world, as well as in public health. BioVeris is also selling two types of M-SERIES instruments for life science research to pharmaceutical and biotechnology researchers, as well as to scientists at academic and government research institutions. The assets and businesses of BioVeris have historically been owned and operated by IGEN. The financial statements of BioVeris have been prepared and are presented as if BioVeris had been operating as a separate entity using the historical cost basis in the assets and liabilities of IGEN and including the historical operations of businesses and assets to be transferred to BioVeris from IGEN as part of the restructuring. Results of operations in the future are likely to fluctuate substantially from quarter to quarter as a result of various factors, which include: - the volume and timing of orders and product deliveries for biodefense products, M-SERIES systems or other products, which orders and deliveries are based on BioVeris's customers' requirements; - the success of M-SERIES system upgrades and enhancements, which upgrades and enhancements involve increased product costs at the time of the upgrade or enhancement, and customer acceptance of those enhancements and upgrades; - the amount of revenue recognized from royalties and other contract revenues, which revenues are dependent upon the efforts of BioVeris's licensees and collaborators; - whether BioVeris's instruments are sold or leased to customers, which will affect the timing of the recognition of revenue from the sale or lease; - the timing of BioVeris's introduction of new products, which could involve increased expenses associated with product development and marketing; - the volume and timing of product returns and warranty claims, which, if products are returned or have warranty claims that are unexpected, may involve increased costs in excess of amounts reserved for returns or claims; - BioVeris's competitors' introduction of new products, which may affect the purchase decision of or timing of orders by BioVeris's customers and prospective customers while the competitors' product is assessed; - the amount of expenses BioVeris incurs in connection with the operation of its business, including - research and development costs, which increases or decreases based on the product in development and - sales and marketing costs, which are based on product launches or promotions and sales incentives that might be in effect from time to time; - the amount that BioVeris will record each quarter related to the amortization or impairment of the license to use PCR technology, which may increase based on the outcome of the litigation and arbitration commenced against Roche by Applied Biosystems relating to Roche's and Applied Biosystems' respective rights to PCR technology; - unexpected termination of government contracts or orders, which could result in decreased sales and increased costs due to excess capacity, inventory personnel and other expenses; and - BioVeris's share of losses in MSD, which are based on results of MSD's operations, which for the three and six months ended September 30, 2003 totaled $4.5 million and $9.7 million, respectively, compared to $5.0 million and $9.5 million for the three and six months ended September 30, 2002. BioVeris expects to incur additional operating losses as a result of its expenses for manufacturing, marketing and sales capabilities, research and product development, general and administrative costs, the 121 expenses of its affiliate and compensation charge associated with a change in the value of IGEN employee stock options in connection with the merger. BioVeris's net loss is expected to increase in the period in which the merger is completed as a result of BioVeris's recognition of an allocated noncash compensation charge associated with the cancelation of IGEN stock options and the payment of the merger consideration for each share covered by IGEN stock options in connection with the merger. BioVeris's ability to become profitable in the future will be affected by, among other things, BioVeris's ability to expand the distribution and increase sales of existing products, upgrade and enhance the M-SERIES family of products, introduce new products into the market, generate higher revenue, develop marketing, sales and distribution capabilities cost-effectively, and continue collaborations established by IGEN or establish successful new collaborations with corporate partners to develop, manufacture, market and sell products that incorporate BioVeris technologies.

Total revenues were $11.0 million for the six months ended September 30, 2003, an increase of $3.5 million or 46% from $7.5 million for the six months ended September 30, 2002. Product sales were $10.4 million for the six months ended September 30, 2003, an increase of $3.4 million or 49% from $7.0 million for the six months ended September 30, 2002. This increase in product sales resulted from sales of products for the life science market of $7.1 million for the six months ended September 30, 2003, an increase of $1.3 million from $5.8 million for the six months ended September 30, 2002 and sales of biodefense products of $3.3 million for the six months ended September 30, 2003, an increase of $2.1 million from $1.2 million for the six months ended September 30, 2002. Sales of products for the life science market increased due to increased sales of the M-SERIES family of products. BioVeris anticipates continued increases in biodefense-related sales as a result of its ongoing biodefense initiatives. As part of the merger and related transactions, BioVeris expects to assume a contract between IGEN and the DOD pursuant to which the DOD may purchase tests for the detection of specific toxins in environmental samples from IGEN. The DOD's legal counsel has reviewed and found acceptable from a legal perspective the form of novation agreement that BioVeris has prepared for transferring the DOD and other U.S. government contracts from IGEN to BioVeris. However, under applicable legal requirements the DOD consent to the transfer of the DOD contracts and other U.S. government contracts cannot be obtained until the restructuring is completed. Under the contract, the DOD may, at its option, make purchases of up to $23.0 million over a period of up to 48 months. As of September 30, 2003, the DOD had purchased approximately $1.7 million of products and, under the contract, may purchase up to a maximum of $7.0 million in the 12-month period ending June 2004. The tests being sold by BioVeris are based on ECL technology and do not depend on any technology licensed from Roche. BioVeris's sales of its products for the life science market are subject to a number of uncertainties, including the fact that BioVeris is not a party to significant long-term contracts for the sale of its products for the life science market that would provide predictable sales. Therefore, the volume and timing of product orders from BioVeris's life science customers are based on their requirements, which may vary over time. As a result, BioVeris believes it does not have sufficient information to reasonably project its future sales in the life science market. Operating Costs and Expenses. Product costs were $5.8 million (55% of product sales) for the six months ended September 30, 2003 compared to $3.0 million (42% of product sales) for the six months ended September 30, 2002. Product costs for the six months ended September 30, 2003, as a percentage of product sales, increased due to costs incurred in connection with instrument upgrades ($300,000 or 3% of product sales) and detection module upgrades ($1.2 million or 11% of product sales) for existing life science customers. These voluntary upgrades were provided to enhance overall customer satisfaction. The instrument and detection module upgrade programs will be substantially complete by December 31, 2003. BioVeris estimates the associated costs for the instrument and detection module upgrade programs to be approximately $200,000 and $1.4 million, respectively, for the quarter ended December 31, 2003. 122 BioVeris's future product costs are subject to a number of uncertainties relating to, among other things, the launch of new instrument systems. Research and development expenses were $10.3 million for the six months ended September 30, 2003, a decrease of $1.6 million or 14% from $11.9 million for the six months ended September 30, 2002, due primarily to lower personnel and facilities costs for development projects. Research and development expenses primarily relate to ongoing development costs and product enhancements associated with the M-SERIES family of products, development of new assays and research and development of new systems and technologies, including point-of-care products. BioVeris expects research and development costs to increase as product development and core research continue to expand, including costs associated with BioVeris's efforts in developing clinical diagnostics and biodefense testing products. Selling, general and administrative expenses were $9.2 million for the six months ended September 30, 2003, a decrease of $1.0 million or 10% from $10.2 million for the six months ended September 30, 2002, due to lower personnel costs. For each of the periods, BioVeris was fully integrated with IGEN and the accompanying consolidated financial statements reflect the application of certain estimates and allocations. BioVeris's consolidated statements of operations include all revenues and costs that are directly attributable to the BioVeris businesses. In addition, certain expenses of IGEN have been allocated to BioVeris using various assumptions that, in the opinion of management, are reasonable. These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs) which were allocated based upon percentage of total revenue or percentage of total headcount, as appropriate. There are no other selling, general and administrative expenses for the six months ended September 30, 2003 and 2002 other than these allocated expenses. Since 1995, IGEN has retained Wilmer, Cutler & Pickering to perform legal services in connection with the Roche litigation and other matters. Mr. Richard Cass, one of IGEN's directors, is a partner of the law firm of Wilmer, Cutler & Pickering and is chairman of its Corporate Practices Group. In addition, Ms. Jennifer M. Drogula, who became the daughter-in-law of IGEN's and BioVeris's chief executive officer in March 2002, has been a partner of the firm since January 2001. BioVeris recorded approximately $100,000 in legal fees to the law firm for each of the six months ended September 30, 2003 and 2002. BioVeris expects that it will continue to retain the law firm in the future. IGEN's and BioVeris's chief executive officer, Mr. Samuel Wohlstadter, is the principal and controlling stockholder, a director and the chief executive officer of each of Wellstat Biologics Corporation, or Wellstat Biologics, Wellstat Therapeutics Corporation, or Wellstat Therapeutics, Hyperion Catalysis International, or Hyperion, and Proteinix Corporation, or Proteinix, which are referred to in this proxy statement/prospectus as the affiliated companies. IGEN's and BioVeris's president and chief operating officer, Dr. Richard Massey, is also a director of Hyperion and a less than 10% stockholder in Proteinix. These companies are therefore considered affiliates of BioVeris for the purpose of this discussion. After completion of the merger and related transactions, BioVeris will have shared services arrangements with each of the affiliated companies. These shared services include accounting and finance, human resources and other administrative services, as well as facility related costs and services. Shared services costs allocated to these companies totaled $600,000 and $500,000 for the six months ended September 30, 2003 and 2002, respectively, which reduced certain operating costs and expenses for the respective periods. Amounts allocated to the affiliated companies are calculated and billed monthly based upon costs incurred by BioVeris and are determined through allocation methods that include time-spent and square footage utilized. Amounts due from affiliated companies under these shared services agreements were approximately $300,000 and $39,000 at September 30, 2003 and 2002, respectively, and were paid subsequent to each respective period end. See "Certain Relationships and Related Party Transactions." Interest Expense and Other. Interest expense, net of other income, was approximately $48,000 and $200,000 of income for the six months ended September 30, 2003 and 2002, respectively. 123 Equity in Loss of Joint Venture. MSD is a joint venture formed by IGEN and MST in 1995. MSD was formed for the development, manufacture, marketing and sale of products utilizing a proprietary combination of MST's multi-array technology together with IGEN's technology. BioVeris has recorded its proportionate share of MSD losses, representing approximately 100% of MSD's losses, for the six months ended September 30, 2003 and 2002. As part of the merger and related transactions, IGEN will transfer its interest in MSD to BioVeris. Equity in loss of joint venture was $9.7 million for the six months ended September 30, 2003 and $9.5 million for the six months ended September 30, 2002. See "Description of the BioVeris Business -- Collaborations and License Arrangements -- MSD" and "Certain Relationships and Related Party Transactions -- MSD and MSD Agreements." MSD's losses increased in fiscal 2003 primarily due to higher costs associated with its transition from a development stage entity to a commercial operating company. MSD had not commenced commercial operations during fiscal 2002 and its product sales commenced in October 2002. The increase in MSD's losses during the six months ended September 30, 2003 results primarily from increases in sales and marketing expenses which were offset only in part by the growth in revenues. MSD manufactures markets and sells instrument systems, including the Sector HTS and the Sector PR, which combine MST's multi-array technology and IGEN's ECL technology. The Sector HTS is an ultra high throughput drug discovery system engineered for applications such as high throughput screening and large-scale proteomics. The Sector PR is a smaller system designed for benchtop applications such as assay development, research in therapeutic areas, cellular biology and medium throughput screening. MSD also manufactures and markets its own line of reagents, assays and plates that are used on these systems. As of September 30, 2003, MSD had cash and short-term investments of $5.0 million with working capital of $8.6 million. During the six months ended September 30, 2003, MSD used $1.8 million for the purchase of inventory and $1.3 million for the purchase of property, equipment and leasehold improvements. See "Liquidity and Capital Resources" for a discussion of our funding commitments to MSD. Net Loss. BioVeris's net loss was $23.8 million for the six months ended September 30, 2003, a decrease of $3.1 million or 11% from $26.9 million for the six months ended September 30, 2002. BioVeris's net loss is primarily caused by its operating expenses, and its equity in loss of joint venture, exceeding its revenues. The decrease in net loss from the prior period is primarily due to growth in BioVeris's product sales. BioVeris's net loss is expected to increase in the period in which the merger is completed as a result of BioVeris's recognition of an allocated one-time noncash compensation charge associated with the cancelation of IGEN stock options and the payment of the merger consideration for each share covered by IGEN stock options in connection with the merger. Upon completion of the merger, depending on the average first day trading price of BioVeris common stock, BioVeris will record a compensation charge for each IGEN stock option. BioVeris cannot predict what the average first day trading price of its common stock will be, however the table set forth below provides a range of hypothetical average first day trading prices for BioVeris common stock and the projected compensation charge if such price is the actual average first day trading price. The hypothetical average first day trading prices for BioVeris common stock have been provided for illustrative purposes only and are not intended to forecast or be indicative of the possible future performance of BioVeris common stock and BioVeris cannot provide any assurance that the average first day trading price of its common stock will be equal to any of the prices in the table set forth below. The table below includes the approximate compensation charge attributable to employee and 124 nonemployee stock options based on these hypothetical average first day trading prices for BioVeris common stock. APPROXIMATE HYPOTHETICAL AVERAGE FIRST DAY PROJECTED NONCASH TRADING PRICE OF COMPENSATION BIOVERIS COMMON STOCK CHARGE ------------------------------ ----------------- $0.00....................................................... $ 8,200,000 $5.00....................................................... 9,600,000 $10.00...................................................... 11,000,000 $11.75...................................................... 11,500,000 $12.00...................................................... 43,100,000 $15.00...................................................... 46,300,000 In calculating the projected compensation charge associated with the merger and related transactions, BioVeris applied the guidance of FIN 44 for employee stock options and SFAS 123 for nonemployee stock options. Under FIN 44, an assumption must be made as to the final closing price of IGEN common stock immediately prior to the merger. For this purpose, a final closing price of $59.00 per share has been assumed. In the merger, IGEN stockholders will be entitled to receive for each share of IGEN common stock they hold $47.25 in cash, without interest, and one share of BioVeris common stock, which yields an assumed, pre-spinoff value of BioVeris of $11.75 ($59.00 less $47.25). Under FIN 44 guidance, if the average first day trading price of BioVeris (post-spinoff value) exceeds $11.75, both vested and unvested employee stock options at the merger date are included in calculating the compensation charge. Alternatively, if the average first day trading price of BioVeris is less than or equal to $11.75, only the unvested employee stock options that have been accelerated are included in calculating the compensation charge. Under SFAS 123 guidance, the compensation charge is calculated based upon the incremental fair value for the nonemployee stock options resulting from the merger. YEARS ENDED MARCH 31, 2003 AND 2002 Revenues. Total revenues were $17.8 million for the fiscal year ended March 31, 2003, an increase of approximately $4.6 million or 34% from $13.2 million in fiscal 2002. Product sales were $16.5 million in fiscal 2003, an increase of $4.4 million or 37% from $12.1 million in fiscal 2002. This increase in product sales resulted from sales of products for the life science market of $11.9 million in fiscal 2003, an increase of $1.0 million from $10.9 million in fiscal 2002, and sales of biodefense products of $4.6 million in fiscal 2003, an increase of $3.4 million from $1.2 million in fiscal 2002. Sales of products for the life science market increase due to increased sales of the M-SERIES family of products. BioVeris anticipates continued increases in biodefense-related sales as a result of its ongoing biodefense initiatives. BioVeris's sales of its products for the life science market are subject to a number of uncertainties, including the fact that BioVeris is not a party to significant long-term contracts for the sale of its products for the life science market that would provide predictable sales. Therefore, the volume and timing of product orders from BioVeris's life science customers are based on their requirements, which may vary over time. As a result, BioVeris believes it does not have sufficient information to reasonably project its future sales in the life science market. Operating Costs and Expenses. Product costs were $8.0 million (49% of product sales) in fiscal 2003 compared to $5.4 million (44% of product sales) in fiscal 2002. Product costs in fiscal 2002 included a write-off of approximately $1.1 million representing the remaining net book value of the TRICORDER detection modules incorporated into customers' M-SERIES systems. The cost of these modules had previously been recorded as a fixed asset and depreciated over their estimated useful life, and should have been recorded as product costs upon shipment and sale. BioVeris determined that the adjustment did not have a material impact on fiscal 2002 or prior period financial statements and, accordingly, did not revise such financial statements. Of the $1.1 million adjustment, approximately $200,000 is related to fiscal 2002 and the remaining $900,000 is related to prior fiscal years (approximately $400,000 and $500,000 related to fiscal 2001 and 2000, respectively). Excluding the $900,000 write-off, product costs were 37% of product 125 sales in fiscal 2002. Product costs in fiscal 2003, as a percentage of product sales, increased from 37%, as adjusted, to 49% primarily due to costs incurred in connection with instrument upgrades for existing life science customers ($1.1 million or 7% of product sales) and warranty costs in excess of the warranty reserve ($600,000 or 4% of products sales). The voluntary instrument upgrades were provided to enhance overall customer satisfaction. The instrument upgrade program, with its associated costs, is expected to continue through December 31, 2003. BioVeris's future product costs are subject to a number of uncertainties relating to, among other things, the launch of new instrument systems. Research and development expenses were $22.8 million in fiscal 2003, a decrease of $4.0 million or 15% from $26.8 million in fiscal 2002. Of the $26.8 million in fiscal 2002, $2.4 million was spent funding MSD joint venture activities prior to the amendment and extension of the MSD joint venture agreements in August 2001. See "-- Equity in Loss of Joint Venture" below for a discussion of activities relating to MSD in fiscal 2003 and 2002. Research and development expenses primarily relate to ongoing development costs and product enhancements associated with the M-SERIES family of products, development of new assays for the life science market and research and development of new systems and technologies, including point-of-care products. Selling, general and administrative expenses were $20.5 million in fiscal 2003, an increase of $1.3 million or 6% from $19.2 million in fiscal 2002. This increase was primarily attributable to additional personnel and support costs required to support the increase in sales and customers. For each of the periods, BioVeris was fully integrated with IGEN and the accompanying consolidated financial statements reflect the application of certain estimates and allocations. BioVeris's consolidated statements of operations include all revenues and costs that are directly attributable to the BioVeris businesses. In addition, certain expenses of IGEN have been allocated to BioVeris using various assumptions that, in the opinion of management, are reasonable. These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs) which were allocated based upon percentage of total revenue or percentage of total headcount, as appropriate. There are no other selling, general and administrative expenses for fiscal 2003 and fiscal 2002 other than these allocated expenses. Since 1995, IGEN has retained Wilmer, Cutler & Pickering to perform legal services in connection with the Roche litigation and other matters. Mr. Richard Cass, one of IGEN's directors, is a partner of the law firm of Wilmer, Cutler & Pickering and is chairman of its Corporate Practices Group. In addition, Ms. Jennifer M. Drogula, who became the daughter-in-law of IGEN's and BioVeris's chief executive officer in March 2002, has been a partner of the firm since January 2001. BioVeris recorded approximately $100,000 and $400,000 in legal fees to the law firm for the years ended March 31, 2003 and 2002, respectively. After completion of the merger and related transactions, BioVeris will have shared services arrangements with each of the affiliated companies. These shared services include accounting and finance, human resources and other administrative services, as well as facility related costs and services. Shared services costs allocated to these companies totaled $1.0 million and $1.3 million in fiscal 2003 and 2002, respectively, which reduced certain operating costs and expenses for the respective years. Amounts allocated to the affiliated companies are calculated and billed monthly based upon costs incurred by BioVeris and are determined through allocation methods that include time-spent and square footage utilized. Amounts due from affiliated companies under these shared services agreements were approximately $200,000 and $100,000 at March 31, 2003 and 2002, respectively, and were paid subsequent to each respective year end. See "Certain Relationships and Related Party Transactions." Interest Expense and Other. Interest expense, net of other income, was approximately $200,000 of income in fiscal 2003 and $39,000 of expense in fiscal 2002. This increase in income was due to foreign currency transaction gains in the fiscal 2003 period. Equity in Loss of Joint Venture. MSD is a joint venture formed by MST and IGEN in 1995. MSD was formed for the development, manufacture, marketing and sale of products utilizing a combination of MST's multi-array technology together with IGEN's technology. Beginning on July 1, 2001, MSD was 126 transitioning from a development stage entity to a commercial enterprise and milestones establishing the continued viability of MSD were first achieved in the quarter ended September 30, 2001. For example, prototypes had been assembled demonstrating product feasability, and MSD was anticipating initial product launch in approximately one year. As a result of this transition, MSD's expenses were no longer primarily research and development. Accordingly, since July 1, 2001, BioVeris has recorded only its proportionate share of MSD losses, representing approximately 100% of MSD's losses, for each respective period as equity in loss of joint venture consistent with accounting for equity method investments. As part of the merger and related transactions, IGEN will transfer its interest in MSD to BioVeris. Equity in loss of joint venture was $17.6 million in fiscal 2003, and $10.9 million in fiscal 2002. In addition, approximately $2.4 million of the fiscal 2002 MSD contributions, all occurring prior to July 1, 2001, were recorded by BioVeris as research and development expenses based upon the significance and character of the MSD losses. In connection with entering into the MSD agreements in August 2001, IGEN transferred certain equipment and leasehold improvements to MSD in an amount of approximately $800,000, which amount is included in the in-kind contributions to MSD in such year. See "Description of the BioVeris Business -- Collaborations and License Arrangements -- MSD" and "Certain Relationships and Related Party Transactions -- MSD and MSD Agreements." MSD's losses increased in fiscal 2003, primarily due to higher costs associated with its transition from a development stage entity to a commercial operating company. MSD commenced product sales in October 2002, and during the year ended March 31, 2003, its product sales totaled $3.2 million. MSD increased its staffing during fiscal 2003 primarily for development personnel and new sales and marketing personnel to support the launch of its products. These personnel increases resulted in higher costs for both research and development and sales and marketing. As of March 31, 2003, MSD had cash and short-term investments of $600,000 with working capital of $3.5 million. During the year ended March 31, 2003, MSD used $2.2 million for the purchase of inventory and $3.9 million for the purchase of property, equipment and leasehold improvements. See "Liquidity and Capital Resources" for a discussion of BioVeris's funding commitments to MSD. Net Loss. BioVeris's net loss was $50.9 million in fiscal 2003, an increase of $1.7 million or 4% from the net loss of $49.2 million in fiscal year 2002. This increase was primarily due to higher losses by MSD in fiscal 2003, reflected as an increase in equity in loss of joint venture, offset by the growth in BioVeris's fiscal 2003 product sales. YEARS ENDED MARCH 31, 2002 AND 2001 Revenues. Total revenues were $13.2 million for fiscal 2002, a decrease of approximately $600,000 or 4% from $13.8 million in fiscal 2001. Product sales were $12.1 million in fiscal 2002, an increase of $3.2 million or 35% from $8.9 million in fiscal 2001. The increase in product sales resulted primarily from sales of products for the life science market of $10.9 million in fiscal 2002, an increase of $2.0 million from $8.9 million in fiscal 2001 due to increased sales of the M-SERIES family of products. Royalty income was $1.1 million in fiscal 2002, an increase of $200,000 or 18% from $900,000 in fiscal 2001. The increase in royalty income was primarily attributable to higher sales by BioVeris's licensees. Contract fees were $100,000 in fiscal 2002, a decrease of $3.9 million or 97% from $4.0 million in fiscal 2001. This decrease was primarily due to non-recurring contract fees in fiscal 2001 in connection with an alliance with Bayer Diagnostics. Operating Costs and Expenses. Product costs were $5.4 million (44% of product sales) in fiscal 2002 compared to $3.1 million (35% of product sales) in fiscal 2001. Product costs in fiscal 2002 included a write-off of approximately $1.1 million representing the remaining net book value of TRICORDER(R) detection modules incorporated into customers' M-SERIES systems. The cost of these modules had previously been recorded as a fixed asset and depreciated over their estimated useful life, and should have been recorded as product costs upon shipment and sale. BioVeris determined that the adjustment did not have a material impact on fiscal 2002 or prior period financial statements and, accordingly, did not revise such financial statements. Of the $1.1 million adjustment, approximately $200,000 is related to fiscal 2002 127 and the remaining $900,000 is related to prior fiscal years (approximately $400,000 and $500,000 related to fiscal 2001 and 2000, respectively). Excluding the $900,000 write-off, product costs were 37% of product sales in fiscal 2002. Research and development expenses were $26.8 million in fiscal year 2002, a decrease of $1.2 million or 4% from $28.0 million in fiscal 2001. Of the $26.8 million in fiscal 2002, $2.4 million was spent funding MSD joint venture activities prior to the amendment and extension of the MSD joint venture agreements in August 2001. Of the $28.0 million in fiscal 2001, $8.3 million was spent funding MSD joint venture activities. See "-- Equity in Loss of Joint Venture" below for a discussion of MSD activity in fiscal 2002. The fiscal 2002 increase in other research and development expense of $4.6 million, or 23%, primarily relate to ongoing development costs and product enhancements associated with the M-SERIES family of products, development of new assays for the life science market and research and development of new systems and technologies, including point-of-care products. Selling, general and administrative expenses were $19.2 million in fiscal 2002, an increase of $6.0 million or 46% from $13.2 million in fiscal 2001. This increase was primarily attributable to additional personnel costs of approximately $4.4 million required to support the increase in sales and customers, as well as legal and other expenses of $1.6 million largely associated with the amendment and extension of the MSD agreements. For each of the periods, BioVeris was fully integrated with IGEN and the accompanying consolidated financial statements reflect the application of certain estimates and allocations. BioVeris's consolidated statements of operations include all revenues and costs that are directly attributable to the BioVeris businesses. In addition, certain expenses of IGEN have been allocated to BioVeris using various assumptions that, in the opinion of management, are reasonable. These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs) which were allocated based upon percentage of total revenue or percentage of total headcount, as appropriate. There are no other selling, general and administrative expenses for fiscal 2002 and fiscal 2001 other than these allocated expenses. Since 1995, IGEN has retained Wilmer, Cutler & Pickering to perform legal services in connection with the Roche litigation and other matters. Mr. Richard Cass, one of IGEN's directors, is a partner of the law firm of Wilmer, Cutler & Pickering and is chairman of its Corporate Practices Group. In addition, Ms. Jennifer M. Drogula, who became the daughter-in-law of IGEN's and BioVeris's chief executive officer in March 2002, has been a partner of the firm since January 2001. BioVeris recorded approximately $400,000 and $200,000 in legal fees to the law firm for the years ended March 31, 2002 and 2001, respectively. After completion of the merger and related transactions, BioVeris will have shared services arrangements with each of the affiliated companies. These shared services include accounting and finance, human resources and other administrative services, as well as facility related costs and services. Shared services costs allocated to these companies totaled $1.3 million and $1.4 million in fiscal 2002 and 2001, respectively, which reduced certain operating costs and expenses for the respective years. Amounts allocated to the affiliated companies are calculated and billed monthly based upon costs incurred by BioVeris and are determined through allocation methods that include time-spent and square footage utilized. Amounts due from affiliated companies under these shared services agreements were approximately $100,000 at each of March 31, 2002 and 2001, and were paid subsequent to each respective year end. See "Certain Relationships and Related Party Transactions." Interest Expense and Other. Interest expense, net of other income, was $39,000 in fiscal 2002 and approximately $200,000 in fiscal 2001. This decrease is due to foreign currency transaction losses in the fiscal 2002 period. Equity in Loss of Joint Venture. MSD is a joint venture formed by MST and IGEN in 1995. MSD was formed for the development, manufacture, marketing and sale of products utilizing a proprietary combination of MST's multi-array technology together with IGEN's technology. Beginning on July 1, 2001, MSD was transitioning from a development stage entity to a commercial enterprise and milestones 128 establishing the continued viability of MSD were first achieved in the quarter ended September 30, 2001. For example, prototypes had been assembled demonstrating product feasability, and MSD was anticipating initial product launch in approximately one year. As a result of this transition, MSD's expenses were no longer primarily research and development. Accordingly, since July 1, 2001, BioVeris has recorded only its proportionate share of MSD losses, representing approximately 100% of MSD's losses, for each respective period as equity in loss of joint venture consistent with accounting for equity method investments. As part of the merger and related transactions, IGEN will transfer its interest in MSD to BioVeris. For fiscal 2002, equity in loss of joint venture was $10.9 million. In addition, approximately $2.4 million of the fiscal 2002 MSD contributions, all occurring prior to July 1, 2001, and approximately $8.3 million of the fiscal 2001 MSD contributions, were recorded by BioVeris as research and development expenses based upon the significance and character of the MSD losses. In connection with entering into the MSD agreements in August 2001, IGEN transferred certain equipment and leasehold improvements to MSD in an amount of approximately $800,000, which amount is included in the in-kind contributions to MSD in such year. See "Description of the BioVeris Business -- Collaborations and License Arrangements -- MSD", and "Certain Relationships and Related Transactions -- MSD and MSD Agreements." During fiscal 2002, MSD had not commenced commercial operations and its losses increased primarily due to higher costs associated with increasing its staffing primarily for research and development and sales and marketing personnel. As of March 31, 2002, MSD had cash and short-term investments of $4.2 million with working capital of $3.7 million. During the year ended March 31, 2002, MSD used $2.0 million for the purchase of property and equipment. See "Liquidity and Capital Resources" for a discussion of our funding commitments to MSD. Net Loss. BioVeris's net loss was $49.2 million in fiscal 2002, an increase of $18.5 million or 60% from the net loss of $30.7 million in fiscal 2001. This increase was primarily due to a decline in contract fee revenue as well as higher selling, general and administrative expenses and losses attributable to MSD's activities. LIQUIDITY AND CAPITAL RESOURCES In connection with the merger and related transactions, Roche will loan to IGEN $214 million minus the amount of cash received by IGEN from the exercise of IGEN stock options and warrants from July 24, 2003 to the date that is two business days prior to the completion of the merger. These funds, less transaction costs, will be contributed by IGEN to BioVeris as part of the restructuring. The related promissory note will remain the obligation of IGEN and BioVeris will have no obligations associated with this debt. After the PCR license payment of $50 million to certain affiliates of Roche and the final capital contribution of $37.5 million (of which any amount in excess of $30 million will be funded by Mr. Samuel Wohlstadter, IGEN's and BioVeris's chairman and chief executive officer through the purchase of shares of BioVeris series B preferred stock that economically mirror the class C interests in MSD to be held by BioVeris) to MSD, BioVeris is expected to commence its operations following completion of the merger with approximately $125 million in cash. IGEN has historically held all cash in a centralized treasury and has provided all of the necessary funding for the operations of BioVeris since the inception of the assumed businesses. Accordingly, as of September 30, 2003, BioVeris had no cash, cash equivalents or short-term investments. IGEN has the ability and intent to fund the businesses being transferred to BioVeris until such time as the merger is completed. Net cash used for operating activities was $12.7 million and $17.4 million, for the six months ended September 30, 2003 and 2002, respectively, and $33.1 million, $34.2 million and $26.5 million for the years ended March 31, 2003, 2002 and 2001, respectively. These changes between periods are primarily due to the size of each period's operating loss, the accounting for contributions to MSD and changes in working capital accounts. BioVeris used cash of $900,000 and $2.0 million during the six months ended September 30, 2003 and 2002, respectively, and $3.3 million, $5.6 million and $4.9 million during the years ended March 31, 129 2003, 2002 and 2001, respectively, for the acquisition of equipment and leasehold improvements. BioVeris's investments in MSD totaled $15.3 million and $10.8 million for the six months ended September 30, 2003 and 2002, respectively, and $20.5 million and $16.4 million for the years ended March 31, 2003 and 2002, respectively. The tax allocation agreement provides that Roche and IGEN will be solely liable for, will jointly and severally indemnify BioVeris against, and will be entitled to receive and retain all refunds of, taxes (other than transfer taxes) directly or indirectly resulting from, arising in connection with or otherwise related to the merger and related transactions, any transaction undertaken to prepare for the merger and related transactions and any of the actions taken pursuant to the ongoing litigation agreement. This agreement also provides for BioVeris to make a payment to IGEN of up to $20 million. The amount of the payment will depend upon the average of the high and the low trading prices of BioVeris common stock on the first day of trading after the completion of the merger. A payment will be due if such average is at least approximately $11.41 per share and the maximum payment will be due if such average exceeds approximately $13.28, in each case based on the assumption that BioVeris will have $205 million in cash and cash equivalents immediately after completion of the merger and prior to making any payments due pursuant to the related transaction agreements, the ongoing commercial agreements or the MSD letter agreement. The distribution of BioVeris stock will be a taxable transaction for IGEN and the purpose of this payment is for BioVeris to share in a portion of the tax that IGEN might incur as a result of that distribution. The formula, which takes into account the expected approximate tax basis and tax rate that would be used in IGEN's calculation of its tax, was negotiated by Roche and IGEN as part of the overall negotiation of the merger. BioVeris believes that material commitments for capital expenditures and additional or expanded facilities may be required in a variety of areas, such as product development programs. BioVeris is evaluating new facilities for development, manufacturing and other corporate uses and is negotiating to secure new space, which if concluded, would result in additional facilities costs. BioVeris has not, at this time, made material commitments for any such capital expenditures or facilities and has not secured additional sources, if necessary, to fund such commitments. Net cash provided by financing activities was $29.0 million and $30.2 million, for the six months ended September 30, 2003 and 2002, respectively, and $57.0 million, $56.3 million and $31.5 million for the years ended March 31, 2003, 2002 and 2001, respectively. These amounts in each respective period primarily represent the cash contributed, net of receipts, by IGEN to BioVeris. As of September 30, 2003, BioVeris's material future obligations were as follows: SIX MONTHS YEARS ENDED MARCH 31, ENDED ---------------------------------------------- MARCH 31, 2009 AND CONTRACTUAL OBLIGATIONS TOTAL 2004 2005 2006 2007 2008 THEREAFTER ----------------------- -------- ---------- ------ ------ ------ ------ ---------- (IN THOUSANDS) PCR license fee.......... $ 50,000 $ 50,000 $ -- $ -- $ -- $ -- $ -- MSD funding commitment(1).......... 42,854 42,854 -- -- -- -- -- Operating leases(2)...... 20,565 1,161(3) 3,169 3,228 3,280 3,352 6,375 -------- -------- ------ ------ ------ ------ ------ Total contractual obligations............ $113,419 $ 94,015 $3,169 $3,228 $3,280 $3,352 $6,375 -------- -------- ------ ------ ------ ------ ------ ------------ (1) Includes a final capital contribution of $37.5 million to MSD from BioVeris following the completion of the merger, of which any amount in excess of $30 million will be funded by IGEN's and BioVeris's chairman and chief executive officer through the purchase of shares of BioVeris series B preferred stock that economically mirror the class C interest in MSD to be held by BioVeris. (2) Includes amounts under leases entered into after September 30, 2003. 130 (3) Excludes $196,000 with respect to operating leases that will be allocated to MSD through December 31, 2003. These amounts are included in the MSD funding commitment amount in the line immediately above. Following the completion of the merger, and after paying certain obligations including the PCR license fee and satisfying the MSD funding commitment described below, BioVeris expects to commence its operations with approximately $125 million in cash. BioVeris will pay certain affiliates of Roche a fee of $50 million for a worldwide, non-exclusive license under patents that cover certain PCR inventions in accordance with the PCR product license agreement. BioVeris will also owe royalties on sales of the licensed products and on sales of any instrument, accessory, device or system sold for use with the licensed products and on the performance of licensed tests. BioVeris will amortize the license fee over an estimated useful life of 10 years based upon a consideration of the range of patent lives and the weighted average remaining life of the most important underlying patents as well as a consideration of technological obsolescence and product life cycles. BioVeris does not currently sell, or have under development, any product based on the PCR technology being licensed from Roche. MSD is a joint venture formed by MST and IGEN in 1995. As part of the merger and related transactions, IGEN's equity interest in the MSD joint venture will be transferred to BioVeris. Under the MSD agreements, IGEN's funding commitment was based on an annual budget of MSD approved by the JVOC. IGEN's remaining funding commitment may be satisfied in part through in-kind contributions of scientific and administrative personnel and shared facilities. In accordance with the MSD joint venture agreement, the value of these in-kind contributions is based upon costs incurred by BioVeris as determined through allocation methods that include time-spent and square footage utilized. During the years ended March 31, 2003, 2002 and 2001 and the six months ended September 30, 2003 and 2002, operating costs allocated to MSD by BioVeris in connection with shared personnel and facilities totaled $11.9 million, $11.4 million, $5.6 million, $4.1 million and $5.8 million, respectively. Since July 1, 2001, these operating costs allocated to MSD reduced BioVeris's operating costs and expenses and increased the equity in loss of joint venture in the consolidated statements of operations. The JVOC approved funding for MSD for the period from January 1, 2003 to November 30, 2003 in an amount of $20.6 million, subject to a permitted variance of 15%. As of September 30, 2003, the remaining funding commitment to MSD was $5.4 million. Upon the completion of the merger, the MSD joint venture agreement will expire. Following completion of the merger, BioVeris will use its cash to make a final capital contribution of $37.5 million to MSD. Of the final capital contribution of $37.5 million, any amount in excess of $30 million will be funded by IGEN's and BioVeris's chairman and chief executive officer through the purchase of shares of BioVeris series B preferred stock that economically mirror the class C interest in MSD to be held by BioVeris. Under the terms of the series B preferred stock, BioVeris may redeem the BioVeris series B preferred stock for $0.01 per share at any time BioVeris is no longer entitled to receive distributions with respect to the class C interests described in the previous sentence pursuant to the MSD limited liability company agreement. BioVeris will redeem a proportionate part of the BioVeris series B preferred stock in connection with any redemption by MSD of the class C interests held by BioVeris in MSD described in the previous sentence. No distributions on the BioVeris series B preferred stock will be paid unless and until distributions are paid on such class C interests in accordance with the MSD limited liability company agreement, in which event distributions on the BioVeris series B preferred stock will be paid in the same manner and amount as such distributions on the class C interests. The shares of BioVeris series B preferred stock will be entitled in the aggregate to 1,000 votes on all matter on which holders of BioVeris common stock may vote. In addition, BioVeris may not consent to any adverse change to the terms of the class C interests in MSD described in this paragraph without the consent of the holders of the BioVeris series B preferred stock. For a more complete description of BioVeris series B preferred stock, see "Description of BioVeris Capital Stock -- Preferred Stock -- Series B Preferred Stock." BioVeris's obligation to make the final contribution to MSD is separate from its remaining obligation to provide funding to MSD through November 30, 2003. For the six months ended September 30, 2003 131 and 2002, total contributions to MSD were $15.3 million and $10.8 million, respectively, including $3.7 million in the six months ended September 30, 2003, which related to the permitted budget variances from prior years. For the years ended March 31, 2003, 2002 and 2001, contributions to MSD were $20.5 million, $19.6 million and $8.3 million, respectively. In addition, the indemnified parties and IGEN entered into a letter agreement dated August 15, 2001, which will be assumed by BioVeris as part of the restructuring. Pursuant to the letter agreement, IGEN agreed to fund the reasonable ongoing legal fees and related charges and costs incurred by the indemnified parties arising out of or related to the Roche litigation, including any legal fees and related charges and costs arising out of or related to any of IGEN's ongoing negotiations regarding, and the settlement of, the Roche litigation. BioVeris has no pending or known funding obligations under the letter agreement that would have a material adverse effect on its financial position or results of operations. IGEN, BioVeris and MSD agreed that the MSD joint venture agreement will expire on the later of - November 30, 2003, or - the earlier of (1) the date of the completion of the merger and related transactions or (2) the termination of the merger and related transactions in accordance with the terms of the agreements governing such transaction. IGEN, BioVeris and MSD also agreed that funding for MSD would not be extended other than pursuant to the agreements related to the Roche merger and related transactions. In addition, in accordance with the MSD agreements, MST and MSD have the right to terminate the MSD joint venture agreement under certain circumstances, including - breach of IGEN's obligations, including IGEN's funding obligations to MSD, - MSD's termination of Jacob Wohlstadter's employment (other than for cause or disability), - if Jacob Wohlstadter is entitled to terminate his employment agreement for good reason (as defined in his employment agreement) or - upon a change in control of IGEN, as defined. MSD and Jacob Wohlstadter have each agreed that the merger and related transactions will not constitute a change in control for purposes of the MSD agreements and the Jacob Wohlstadter employment agreement. As part of the restructuring, IGEN's equity interest in MSD will be transferred to BioVeris because Roche did not want to acquire the interest. MSD and MST do not have the right to purchase IGEN's or BioVeris's, as the case may be, interest in MSD until the MSD joint venture agreement expires, or in certain cases, is terminated. The MSD joint venture agreement will expire upon completion of the merger and, as a result, MSD and MST will have the right to purchase for a purchase price equal to fair market value (to be determined in accordance with the provisions and procedures set forth in the MSD agreements, which will include a determination by appraisers if the parties are unable to agree on fair market value), less a 7.5% discount factor, BioVeris's entire interest in MSD, including BioVeris's preferred interests that entitle it to a preferred return on its investment in MSD. The MSD joint venture agreement also could be terminated prior to its expiration as a result of a breach of IGEN's obligations, including IGEN's funding obligations to MSD, or as a result of MSD's termination of Mr. Jacob Wohlstadter's employment (other than for cause or disability), in which case MSD and MST would have the right to purchase IGEN's or BioVeris's, as the case may be, interest in MSD, but BioVeris has no reason to believe such an event will occur. BioVeris will no longer be entitled to a preferred return on its investment in MSD in the event MSD or MST elects to purchase BioVeris's interest in MSD. If MSD or MST exercises this right, it will be required to pay IGEN or BioVeris, as the case may be, the outstanding purchase price plus simple (cumulated, not compounded) interest at the fixed annual rate of 0.5% over the prime rate in effect on the date that MSD or MST, as the case may be, elects to purchase the interests. The purchase price is payable over time in installments equal to the sum of 5% of MSD net sales, as determined in accordance with MSD agreements, and 20% of the net proceeds realized by MSD from the sale of its debt or equity securities in any third-party financing after the date of the sale of IGEN's or BioVeris's, as the case may be, interest in MSD. In the event such future net sales or third-party financings do not materialize, BioVeris will not receive any payments from MSD or MST, as the 132 case may be, for the purchase of BioVeris's interest in MSD. As security for the payment obligation, IGEN or BioVeris, as the case may be, will hold a security interest in the interests in MSD that are being purchased. MST or MSD, as the case may be, may repay all or any part of the outstanding purchase price plus accrued interest at any time and from time to time without penalty. Following the expiration of the MSD joint venture agreement, many of the licenses and other arrangements with MSD and MST assigned to BioVeris will continue indefinitely in accordance with their terms. These include: - the IGEN/MSD license agreement, pursuant to which BioVeris granted to MSD a worldwide, perpetual, exclusive license (with certain exceptions) to BioVeris's technology, including ECL technology, for use in MSD's research program, defined in the MSD agreements; and - the MSD/MST sublicense agreement (but only as to IGEN or BioVeris technology or improvements developed before IGEN or BioVeris ceases to be a member of MSD), pursuant to which MST was granted a worldwide, perpetual, non-exclusive sublicense to use BioVeris's technology to make, use or sell products or processes applying or related to the technologies used in the MSD research program outside the diagnostic field. In addition, certain of BioVeris's obligations under the MSD joint venture agreement will survive its expiration or termination, including: - to cooperate and work in good faith and use reasonable best efforts to assist MSD in securing third-party financing, - confidentiality obligations, - to make available to MSD the benefits of certain agreements with third-party licensors, suppliers, vendors, distributors and other providers, - to assign to MSD all proprietary information and intellectual property within the MSD research program or research technologies, as described in the MSD agreements, and to ensure that its employees protect such proprietary information, - to defend and indemnify MSD against all claims arising out of the conduct of the MSD research program and to maintain liability insurance to cover the risk of liability resulting from the conduct of that program, and - unless MSD or MST exercises its right to purchase BioVeris's interests in MSD, not to vote against or refuse to consent to, agree to or approve any action supported by MST unless a committee of the BioVeris board of directors reasonably concludes, after having considered the interests of MSD, that the action is not in the best interests of BioVeris and its stockholders. Notwithstanding expiration or termination of the MSD joint venture agreement, BioVeris will be required to continue to pay the expenses associated with prosecuting and maintaining the patents licensed by MST to MSD in connection with the original formation of the MSD joint venture unless and until MSD or MST exercises its right to purchase BioVeris's interests in MSD. Following the expiration or termination of the MSD joint venture agreement, MSD will be entitled to continue to lease certain facilities and related equipment from BioVeris (including laboratory facilities located in BioVeris's corporate headquarters) pursuant to the terms of the existing sublease agreements with MSD. The term of each sublease will expire one day prior to the expiration of the prime lease for that facility. Each sublease agreement provides that, subject to certain exceptions, BioVeris must exercise all available extension rights under the prime lease. Following termination or expiration of the MSD joint venture agreement, each of MSD and BioVeris may unilaterally terminate any or all of the subleases by providing at least 18 months prior written notice of termination. If BioVeris elects to terminate a sublease for a facility, MSD may elect, notwithstanding any termination of the sublease, to remain in the subleased facility after the 18-month period expires for any period of time selected by MSD, but not longer than one day prior to the expiration of the prime lease (including any extensions of the prime lease). After a notice of termination of a sublease has been sent, MSD will be required to pay its pro rata share of all rental and 133 other expenses incurred by BioVeris under the prime lease. MSD and MST may elect, if either exercises its right to purchase BioVeris's interests in MSD, to have its rental and expense payment obligations for the 18-month period included in the purchase price of those interests in MSD. MSD has an employment agreement with Mr. Jacob Wohlstadter, its president and chief executive officer, the current term of which runs through November 30, 2004. The term of the employment agreement will automatically renew for a 12-month period on November 30 of each year unless either MSD or Mr. Jacob Wohlstadter gives notice of termination no later than 180 days prior to that renewal date. That employment agreement provides for a salary at the annual rate of $250,000 through November 30, 2003. Thereafter, the salary is to be increased as agreed to by MSD and Mr. Jacob Wohlstadter. In addition, Mr. Jacob Wohlstadter is also eligible to receive, at the discretion of the JVOC of the IGEN or BioVeris board of directors, as the case may be, an annual cash bonus in an amount not to exceed 20% of his annual salary. Mr. Jacob Wohlstadter is also entitled to receive pension, welfare and fringe benefits comparable to those received by senior executives of BioVeris and other insurance benefits. If MSD terminates the employment agreement without cause, or Mr. Jacob Wohlstadter terminates the employment agreement for good reason (which includes a "change in control" of BioVeris, as defined), Mr. Jacob Wohlstadter will be entitled to receive, in addition to salary and pro rata bonus and adjustments earned through the 60th day following the notice of termination, an amount equal to from 3 to 12 times (depending on the reason for the termination) the monthly pro rata salary, bonus and adjustments in effect at the time of the termination. Under the employment agreement, Mr. Jacob Wohlstadter is also entitled to receive a gross-up for any "parachute" excise tax that may be imposed on payments made or benefits provided pursuant to the agreement. In addition, upon such a termination prior to the expiration of the MSD joint venture agreement, MSD and MST will have a joint right to purchase BioVeris's interest in MSD on the terms described above. BioVeris will be responsible directly or indirectly for all amounts payable, costs incurred and other obligations under the employment agreement prior to the termination of BioVeris's funding obligation to MSD upon completion of the merger, which generally are expected to be paid out of its funding commitment to MSD. That funding commitment ends when the merger is completed as will most of BioVeris's obligations under the employment agreement, except that BioVeris will remain obligated to maintain in effect directors and officers liability insurance coverage for Mr. Jacob Wohlstadter and to pay Mr. Jacob Wohlstadter the applicable salary, pro rata bonus and adjustments in effect at the time of termination as described above and a gross-up for any "parachute" excise tax that may be imposed. MSD and Mr. Jacob Wohlstadter have each agreed that the merger and related transactions will not constitute a change in control for purposes of the MSD agreements and the employment agreement. BioVeris will also indemnify Mr. Jacob Wohlstadter against certain liabilities, including liability from the MSD joint venture relating to the period of IGEN's or BioVeris's involvement with MSD. In addition, BioVeris will be obligated under the MSD agreements to indemnify each board member or officer of MSD with respect to any action taken by such person prior to termination of MSD joint venture agreement by reason of the fact that such person is or was a board member or an officer of MSD. With respect to such indemnification obligations, there are no pending or known matters covered by these indemnification provisions that would have a material effect on BioVeris's financial position or results of operations. Mr. Jacob Wohlstadter has a consulting agreement with IGEN that will be assumed by BioVeris. This consulting agreement will be automatically renewed on August 15, 2004, for a period of three years unless either BioVeris or Mr. Jacob Wohlstadter gives notice to the contrary no later than 90 days before that date. Pursuant to the consulting agreement, Mr. Jacob Wohlstadter will be entitled to receive such fees as BioVeris and Mr. Jacob Wohlstadter agree to when consulting services are requested by BioVeris. BioVeris has no obligation to request any consulting services from Mr. Jacob Wohlstadter. During fiscal 2002, Mr. Jacob Wohlstadter received $275,000 from IGEN for consulting services performed for IGEN for the period 1995 through 2001. Mr. Jacob Wohlstadter did not perform any compensable consulting services during fiscal 2002, 2003 or the six months ended September 30, 2003. In his role as a consultant, Mr. Jacob Wohlstadter also received stock option grants from IGEN. In May 1997, he was granted options to purchase 180,000 shares of IGEN common stock with an exercise price of $6.00 per share, which was the fair market value on the date of grant. These options will expire on May 8, 2007, and are fully vested. In August 2000, Mr. Jacob Wohlstadter was granted options to purchase 75,000 shares of 134 IGEN common stock, with an exercise price of $18.75 per share, which was the fair market value on the date of grant. These options will expire on August 1, 2010, and 48,749 shares are exercisable as of December 1, 2003. Upon completion of the merger, these options will be canceled and Mr. Jacob Wohlstadter will have the right to receive for each share covered by such option cash from Roche equal to the excess of $47.25 over the exercise price of such option (without interest) and one share of BioVeris common stock. For a description of the accounting treatment of Mr. Jacob Wohlstadter's stock options, see "Notes to Consolidated Financial Statements -- Note 3 -- Stock Option Plans." Mr. Jacob Wohlstadter and JW Consulting Services, L.L.C., a company established and wholly-owned by Mr. Jacob Wohlstadter, have an indemnification agreement with IGEN that BioVeris will assume. Pursuant to the indemnification agreement, BioVeris will indemnify Mr. Jacob Wohlstadter and JW Consulting Services, L.L.C. against any claims arising out of the performance or non-performance of services to or for the benefit of BioVeris. For more information about the MSD agreements and BioVeris's relationship with MSD, see "Certain Relationships and Related Party Transactions." Product development for BioVeris's clinical diagnostic products is at an early development stage and products based on the PCR technology being licensed from Roche are not yet under development. Product development is subject to a number of technical and commercial uncertainties and in part depends upon BioVeris's ability to enter into new collaborative arrangements. Accordingly, BioVeris has not yet completed a business plan for its clinical diagnostic products, including immunodiagnostic and PCR technology-based products, does not have definitive product introduction timelines or budgets and has not determined the additional funding, personnel, facilities, equipment or technology that may be required to implement its plans. BioVeris's ability to become profitable in the future will depend on, among other things, the introduction of new products to the market. If BioVeris is unable to develop new products, including products based on PCR technology, its business prospects and financial results would be adversely affected. Furthermore, BioVeris will need substantial amounts of money to fund its operations on an ongoing basis. BioVeris expects its available cash to be sufficient to fund its operations for at least one year, but it cannot predict how long its available cash will be sufficient to fund its operations thereafter. In this regard, BioVeris expects that it will from time to time have discussions with third parties, including multinational corporations, regarding various business arrangements including distribution, marketing, research and development, joint venture and other business agreements, which could provide for substantial up-front fees or payments. BioVeris cannot assure you that it will successfully complete any of the foregoing arrangements and access to funds could be adversely impacted by many factors, including the volatility of the price of BioVeris common stock, continuing losses from its operations, establishment of new business arrangements, the status of new product launches, general market conditions and other factors described under "Risk Factors" and elsewhere in this proxy statement/prospectus. If BioVeris is unable to raise additional capital, it may have to scale back, or even eliminate, some programs. Alternatively, BioVeris may consider pursuing arrangements with other companies, such as granting licenses or entering into joint ventures or collaborations, on terms that may not be favorable to it. As of September 30, 2003, BioVeris had no off-balance sheet arrangements. CRITICAL ACCOUNTING POLICIES A critical accounting policy is one that is both important to the portrayal of BioVeris's financial position and results of operations and requires the application of difficult, subjective or complex judgments by management. As a result, critical accounting policies are subject to an inherent degree of uncertainty. In applying those policies, management uses its judgment to determine the appropriate assumptions to be used in the determination of certain estimates. These estimates are based on BioVeris's management's experience, terms of existing contracts, observance of trends in the industry, information provided by 135 customers, and information available from other outside sources, as appropriate. BioVeris's critical accounting polices include: Expense Allocations -- The assets and businesses of BioVeris have historically been owned, operated and fully integrated with IGEN. The financial statements of BioVeris have been prepared and are presented as if BioVeris had been operating as a separate entity. In order to fairly present the operating results of BioVeris, these financial statements reflect the application of certain estimates and allocations. BioVeris's consolidated statements of operations include all costs that are directly attributable to the BioVeris businesses, as well as certain expenses of IGEN that have been allocated to BioVeris using various assumptions. These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs) which were allocated based upon percentage of total revenue or percentage of total headcount, as appropriate. While management believes that the allocation methodologies are reasonable and appropriate, different allocation methodologies could result in changes to BioVeris's operating results. Revenue Recognition -- BioVeris derives revenue principally from three sources: product sales, royalty income and contract fees. Product sales revenue is generally recognized when persuasive evidence of an arrangement exists, the price to the buyer is fixed and determinable, collectibility is reasonably assured and the product is shipped to the customers thereby transferring title and risk of loss. For instrument sales, the instrument and the related installation are considered to be separate elements under EITF 00-21. Revenue is recognized for the instrument upon shipment and is recognized for the installation when complete based upon the residual value method. For instrument and reagent sales, there is no option of return and refund, only the option to repair or replace. Other than the installation required for the instruments, there are no contingencies, allowances or other post-sale obligations. For instrument leases, the instrument rental and related minimum reagent purchases are considered to be separate elements under EITF 00-21 and, accordingly, the sales price is allocated to the two elements based upon their relative fair values. Instrument rental revenue is recognized ratably over the life of the lease agreements and the related reagent revenue is recognized upon shipment. Revenue associated with extended warranty arrangements is recognized over the term of the extended warranty contract. Royalty income is recorded when earned, based on information provided by licensees. Revenue from services performed under contracts is recognized when obligations under the contract have been satisfied. The satisfaction of obligations may occur over the term of the underlying customer contract, if the contract is based on the achievement of certain "milestones," or may occur at the end of the underlying customer contract, if based only upon delivery of the final work product. The majority of BioVeris's product sales and contract fees contain standard terms and conditions. Certain transactions may contain negotiated terms that require contract interpretation to determine the appropriate amount of revenue to be recognized. In addition, BioVeris must assess whether collectibility is reasonably assured. While management believes its interpretations and judgments are reasonable, different assumptions could result in changes in the timing of revenue recognition. Joint Venture Accounting -- BioVeris accounts for its ownership in the MSD joint venture on the equity method as it has determined that it does not control MSD's operations. Factors considered in determining BioVeris's level of control include the fact that it has less than 50% of the voting equity interest in MSD; that it does not have exclusive authority over MSD decision making and has no ability to unilaterally modify the joint venture agreements; and that it has the right to appoint only one out of two seats on MSD's board of managers. A different assessment of these factors could provide for the use of consolidation accounting rather than the equity method, in which case a consolidation of BioVeris's financial statements with those of MSD would be appropriate. Consolidation accounting would require certain reclassifications within BioVeris's consolidated financial statements but would not materially effect BioVeris's financial position or net loss. See "Notes to Consolidated Financial Statements -- Note 4 -- Meso Scale Diagnostics Joint Venture." In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities," or FIN 46. FIN 46 provides guidance on variable interest entities such as the MSD joint 136 venture and the framework through which an enterprise assesses consolidation of a variable interest entity. BioVeris adopted FIN 46 as of October 1, 2003 and has determined that MSD qualifies as a variable interest entity under FIN 46 because substantially all of MSD's funding is being provided by BioVeris and BioVeris's voting rights are not proportional to its obligation to absorb a majority of the potential future losses of MSD. Accordingly, beginning October 1, 2003, BioVeris will consolidate the financial results of MSD. Consolidation accounting will require certain reclassifications within BioVeris's consolidated financial statements, but is not expected to materially effect its financial position or net loss, as BioVeris has already recorded approximately 100% of MSD's losses. Historical financial information of MSD is summarized in Note 4 of BioVeris's consolidated financial statements and the audited MSD financial statements are included in the March 31, 2003 IGEN Form 10-K and incorporated by reference into the registration statement of which this proxy statement/prospectus is a part. Allowance for Doubtful Accounts -- BioVeris maintains reserves on customer accounts where estimated losses may result from the inability of its customers to make required payments. These reserves are determined based on a number of factors, including the current financial condition of specific customers, the age of accounts receivable balances and historical loss rates. If the financial condition of BioVeris's customers were to deteriorate, resulting in an impairment of their ability to make payments, an additional allowance may be required. Inventory -- BioVeris records its inventory at the lower of cost or market using the first-in, first-out method. BioVeris regularly reviews inventory quantities on hand and records a reserve for excess and obsolete inventory based primarily on an estimated forecast of product demand and production requirements for the next twelve months. Reserves are recorded for the difference between the cost and the market value. Those reserves are based on significant estimates. BioVeris's estimates of future product demand may prove to be inaccurate, in which case BioVeris may have understated or overstated the provision required for excess and obsolete inventory. In addition, BioVeris's industry is characterized by technological change, frequent new product development and product obsolescence that could result in an increase in the amount of obsolete inventory quantities on hand. Although BioVeris makes every effort to ensure the accuracy of its forecasts of future product demand, any significant unanticipated changes in demand or technological developments could have a significant impact on the values of BioVeris's inventory and BioVeris's reported operating results. Evaluation of Long-lived Assets -- BioVeris has different long-lived assets recorded on its balance sheet that include equipment and leasehold improvements, investments and other assets. BioVeris evaluates the potential impairment of long-lived assets based whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. In evaluating the recoverability of an asset, management's policy is to compare the carrying amount of an asset with the projected undiscounted cash flow. While management believes that its projections are reasonable and that no impairment of these assets exists, different assumptions could affect these evaluations and result in impairment charges against the carrying value of these assets. Warranty Reserve -- BioVeris warrants its products against defects in material and workmanship for one year after sale and records estimated future warranty costs at the time revenue is recognized. A reserve for future warranty claims is recorded based upon management's review of historical results, supplemented by expectations of future costs. Unanticipated changes in actual warranty costs could impact BioVeris's operating results. Capitalized Software Costs -- BioVeris records software development costs in accordance with SFAS No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed." BioVeris applies its judgment in determining when software being developed has reached technological feasibility, and at that point BioVeris would capitalize software development costs. To date, software development has been substantially completed concurrently with the establishment of technological feasibility, and accordingly, no costs have been capitalized to date. 137 RECENT ACCOUNTING PRONOUNCEMENTS In November 2002, the Financial Accounting Standards Board, or FASB, issued Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Guarantees of Indebtedness of Others," or FIN 45. FIN 45 establishes new disclosure and liability recognition requirements for direct and indirect guarantees with specified characteristics. The initial recognition and measurement provisions of FIN 45 are applicable on a prospective basis to guarantees issued or modified after December 31, 2002. The disclosure requirements in FIN 45 are effective for both annual and interim periods ending after December 15, 2002. BioVeris adopted FIN 45 as of March 31, 2003 and the implementation did not have a material effect on its financial position, results of operations or cash flows. In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation -- Transition and Disclosure -- an amendment of SFAS No. 123," or SFAS 148. SFAS 148 amends SFAS 123, "Accounting for Stock-Based Compensation," or SFAS 123, to provide alternative methods of voluntarily transitioning to the fair value based method of accounting for stock-based employee compensation. SFAS 148 also amends the disclosure requirements of SFAS 123 to require disclosure of the method used to account for stock-based employee compensation and the effect of the method on reported results in both annual and interim financial statements. This pronouncement is effective for both annual and interim periods beginning after December 15, 2002. BioVeris has elected to follow the recognition and measurement principles of Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," in its accounting for employee stock options. In accordance with SFAS 148, BioVeris has adopted the annual and interim period disclosure requirements in this proxy statement/ prospectus. In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities," or FIN 46. FIN 46 provides guidance on variable interest entities such as the MSD joint venture and the framework through which an enterprise assesses consolidation of a variable interest entity. BioVeris will adopt FIN 46 as of January 1, 2004 and has determined that MSD qualifies as a variable interest entity based upon the following rationale: - BioVeris has provided substantially all of MSD's funding since inception through capital contributions consisting of class B and C non-voting equity interests. Such funding is not considered "at risk" as the investments do not participate significantly in the profits of MSD given their stated return rates. As such, the "at risk" equity of MSD is insufficient to absorb MSD's expected future losses. - BioVeris holds 31% of the voting rights in MSD while providing 100% of MSD's funding, and BioVeris is thereby considered to be involved in all of MSD's activities as defined under FIN 46. As the merger and related transactions do not change the design of or ownership interests in MSD in such a manner that could affect the status of MSD as a variable interest entity or BioVeris as the primary beneficiary, BioVeris does not believe they are deemed to be events that would require reassessment of BioVeris's previous conclusion that MSD qualifies as a variable interest entity under FIN 46 with BioVeris as the primary beneficiary. Accordingly, beginning January 1, 2004 and continuing subsequent to the completion of the merger and related transactions, BioVeris will consolidate the financial results of MSD. Under the transition guidance of FIN 46, because MSD was created before February 1, 2003, BioVeris will measure the assets, liabilities and noncontrolling interests of MSD as of January 1, 2004 for purposes of the initial consolidation. The amounts of the assets, liabilities and noncontrolling interests will be reflective of their respective carrying amounts had FIN 46 been effective when BioVeris first met the conditions to be the primary beneficiary of MSD upon MSD's inception in 1995. Such carrying amounts are expected to equal MSD's recorded values, which as of September 30, 2003, were approximately $17.0 million, $1.8 million and $10,000, respectively. As BioVeris has historically recorded and will continue to record approximately 100% of MSD's losses, it is anticipated that upon implementation of FIN 46, the consolidated net assets of MSD will approximate the book value of BioVeris's investment in joint venture. As such, consolidation accounting will require certain reclassifications within BioVeris's consolidated financial statements, but it is not expected to materially effect its financial position or net loss. 138 The required balance sheet reclassifications will reclassify the amounts formerly recorded on a "net" basis as investment in joint venture to be reflected on a "gross" basis primarily as cash, accounts receivable, inventory, fixed assets, accounts payable and accrued expenses. The required statement of operations reclassifications will reclassify the amounts formerly recorded on a "net" basis as equity in loss of joint venture to be reflected on a "gross" basis primarily as revenue, product costs, research and development expenses and selling, general and administrative expenses. Historical financial information of MSD is summarized in Note 4 of BioVeris's consolidated financial statements and the audited MSD financial statements are included in the March 31, 2003 IGEN Form 10-K and incorporated by reference into the registration statement of which this proxy statement/prospectus is a part. Historical financial information of MSD is summarized in Note 4 of BioVeris's consolidated financial statements and the audited MSD financial statements are included in the March 31, 2003 IGEN Form 10-K and incorporated by reference into the registration statement of which this proxy statement/prospectus is a part. In April 2003, the FASB issued SFAS No. 149, "Amendment of SFAS No. 133 on Derivative Instruments and Hedging Activities," or SFAS 149. SFAS 149 amends and clarifies, financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities under SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." The amendments set forth in SFAS 149 require that contracts with comparable characteristics be accounted for similarly. SFAS 149 is generally effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. The implementation of SFAS 149 did not have a material effect on BioVeris's financial position, results of operations or cash flows. In May 2003, the FASB issued SFAS No. 150 "Accounting for Certain Financial Instruments with Characteristics of Both Liability and Equity," or SFAS 150. SFAS 150 establishes standards regarding the classification and measurement of certain financial instruments with characteristics of both liabilities and equity. SFAS 150 is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. The implementation of SFAS 150 did not have a material effect on BioVeris's financial position, results of operations or cash flows. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK The assets and businesses of BioVeris have historically been owned and operated by IGEN, which holds all cash in a centralized treasury and has provided all of the necessary funding for the operations of BioVeris. Accordingly, no cash is reflected on the consolidated balance sheets of BioVeris and there are no market risk sensitive instruments. BioVeris is exposed to changes in exchange rates where it sells direct in local currencies, primarily in the United Kingdom and Germany. Certain other foreign sales are denominated in U.S. dollars and have no exchange rate risk. Gains and losses resulting from foreign currency transactions have historically not been material. 139 DESCRIPTION OF THE BIOVERIS BUSINESS BioVeris is a newly formed wholly-owned subsidiary of IGEN. Upon completion of the merger and related transactions, BioVeris will become an independent, publicly-traded company. The assets and businesses of BioVeris have historically been owned and operated by IGEN. The following description of the BioVeris business assumes the restructuring and the merger and related transactions have been completed. OVERVIEW BioVeris develops, manufactures and markets its M-SERIES(R) family of products, which can serve as a platform for diagnostic systems to be used for the detection and measurement of biological or chemical substances. BioVeris incorporates its technologies into its instrument systems, tests and reagents, which are the biological and chemical components used to perform such tests. Using the M-SERIES platform, BioVeris intends to integrate technologies and products to develop small, expandable and modular systems that can perform a wide variety of immunodiagnostic and nucleic acid tests. BioVeris's products are designed to be sold in the worldwide diagnostics markets, including: - Clinical diagnostics. The clinical diagnostics market includes the testing of patient samples to measure the presence of disease and monitor medical conditions. BioVeris is developing products to be used in the clinical diagnostics market and believes that its products are best suited for the immunodiagnostic and nucleic acid testing market segments of the clinical testing market. The immunodiagnostic and nucliec acid testing market segment sizes are estimated to be $6 billion and $1.5 billion, respectively. - Non-clinical diagnostics for the biodefense, life science and industrial markets. The non-clinical diagnostics market includes biodefense products for the detection of bacteria, viruses and toxins that may pose a military or public health threat; life science testing for drug discovery and development that is performed by pharmaceutical and biotechnology companies; and industrial testing for the detection of foodborne and waterborne disease causing pathogens. The life science market size is estimated to be $2.5 billion. BioVeris believes that the emergence of simple, more accurate and cost-effective clinical diagnostic products is shifting the site of clinical diagnostic testing from clinical reference laboratories and central hospital laboratories to decentralized patient care centers, such as physicians' offices, ambulatory clinics, hospital emergency rooms, surgical and intensive care units, hospital satellite laboratories and nurses' stations, which are collectively referred to in this proxy statement/prospectus as clinical point-of-care sites. BioVeris's own product development efforts will initially be focused on M-SERIES instruments and tests for the clinical diagnostics market, particularly for point-of-care sites. BioVeris will seek to develop, market and sell products for the clinical point-of-care market segment through a combination of direct efforts and collaborative arrangements. BioVeris also intends to pursue opportunities in the clinical reference laboratory and central hospital laboratory market segments through collaborative arrangements. The M1-M clinical analyzer is the first clinical diagnostic system being developed by BioVeris and builds on the M-SERIES instruments currently being sold by IGEN in the biodefense and life science markets. BioVeris's initial commercial focus for the M1-M will be to provide cardiac assays that test for heart attack and congestive heart failure. BioVeris is developing the cardiac assays using, among other things, improvements licensed from an affiliate of Roche. BioVeris believes that these improvements will reduce product development timelines. BioVeris also believes that the M1-M clinical analyzer will provide results to a physician rapidly with the same levels of sensitivity, accuracy or consistency as a large instrument in a clinical reference laboratory or in a central laboratory, thereby permitting the physician to make a more timely decision regarding the patient's course of treatment. BioVeris will seek approval from the FDA for the M1-M clinical analyzer and other in vitro diagnostics products at the appropriate stage of their product development. 140 BioVeris's M-SERIES instruments are already being used in biodefense programs for homeland security, including by the DOD. BioVeris believes there will be an increasing opportunity to sell its products for biodefense tools by governmental and military organizations around the world, as well as in public health. BioVeris is also selling two types of M-SERIES instruments for life science research to pharmaceutical and biotechnology researchers, as well as to scientists at academic and government research institutions. BioVeris also intends to pursue opportunities in the biodefense and life science market segments and other opportunities in the healthcare field through a combination of direct efforts and collaborative arrangements. BioVeris will own or have rights to use the trademarks BioVeris, M-SERIES and TRICORDER. IGEN owns the trademarks IGEN, ORIGEN and PATHIGEN, which it will retain in the merger. BioVeris will have no right or interest in those trademarks. This proxy statement/prospectus refers to brand names, trademarks and service marks of other companies and those brand names, trademarks and service marks are the property of those other holders. BioVeris was organized as IGEN Integrated Healthcare, LLC, a Delaware limited liability company on June 6, 2003, and converted to BioVeris Corporation, a newly formed Delaware corporation on September 22, 2003. BioVeris's executive offices are located at 16020 Industrial Drive, Gaithersburg, Maryland 20877. BIOVERIS'S STRATEGY BioVeris's strategy is based on the direct development and sale of its products utilizing its technologies, while at the same time entering into collaborations with third parties that can assist BioVeris in its product development, manufacturing and marketing efforts. Key elements of BioVeris's strategy are to: - Pursue collaborative relationships to accelerate new product development and enhance global manufacturing and marketing capabilities. BioVeris intends to pursue collaborative relationships that would help BioVeris to achieve its goals, particularly with respect to the development and manufacturing of new products and entry into new markets. BioVeris will seek to partner with industry leaders that would complement BioVeris's capabilities by manufacturing or distributing co-developed products through their sales organizations. Negotiations are ongoing with a world leader in mobile electronics and systems technology to manufacture one of BioVeris's instruments. There can be no assurance that these negotiations will result in an agreement with such manufacturer on terms favorable to BioVeris, if at all or that such manufacturer will be successful in manufacturing BioVeris's instruments. - Establish leadership positions in emerging markets. BioVeris has identified new market opportunities and is developing and providing innovative products for those markets based on its technologies and those it may license or acquire. BioVeris had previously identified the emerging biodefense market and utilized its ECL technology and innovation to develop and provide leading edge products for this market. BioVeris plans to continue to develop and launch new products through internal development, collaborations and possibly through acquisitions. BioVeris intends to explore opportunities to continue to expand its presence in the biodefense market and develop products, including unique assays, for the emerging clinical point-of-care diagnostics market. In addition, BioVeris plans to focus on identifying therapeutic peptides and antibodies and on the potential link between the use of these peptides and antibodies and diagnostic tests, which could allow for better treatment of patients by providing physicians the ability to more promptly and efficiently diagnose patients who should take a particular medication. - Develop and market product line extensions and an expanded menu of assays. BioVeris intends to continue to develop and market extensions of its existing products through new instrumentation and an expanded menu of assays. BioVeris plans to extend the M-SERIES family of instruments, which 141 currently includes two commercial products, to include new instruments for the biodefense and clinical point-of-care diagnostics markets. In addition, BioVeris plans to continue to add new assays to its existing menu of currently available assays. For example, BioVeris's biodefense menu of assays currently includes assays for biological agents, such as staphylococcus enterotoxin B and botulinum toxin and BioVeris plans to expand this menu to include additional assays, such as for anthrax and smallpox. Using this approach, BioVeris expects to expand its presence in the market and create brand recognition. BIOVERIS'S TECHNOLOGY BioVeris's M-SERIES(R) family of products will incorporate a number of technologies, including: - ECL technology developed by IGEN and owned by BioVeris; - various improvements to ECL technology developed by Roche Diagnostics and licensed to BioVeris; - polymerase chain reaction technology developed by Roche Diagnostics and licensed to BioVeris for use in several specified markets, including the human and animal in vitro diagnostics markets, which is referred to in this proxy statement/prospectus as PCR technology; and - unit dose cartridge technology for packaging reagents in a ready-to-use format that remain stable at room temperature. In addition, BioVeris is seeking to incorporate novel centrifugation technology for separating serum or plasma from whole blood cells. ECL TECHNOLOGY ECL technology is a technology based on electrochemiluminescence that is protected by patents in the United States and internationally. ECL technology permits the detection and measurement of a biological or chemical substance within a given sample. It works by labeling the targeted substance within a sample using a compound and binding the newly labeled substance to magnetizable beads. The beads can then be separated from the rest of the sample using a magnet. When this newly labeled substance is stimulated, the label emits light at a particular wavelength. The light emitted by the label can be measured with a high degree of accuracy. The level of intensity of the light emitted by the label is determined by the amount of the targeted biological substance present in the sample for the label to attach itself to. Thus, the light emissions permit the accurate detection and measurement of the targeted biological or chemical substance. ECL technology provides a uniform format that can be used to conduct a multitude of tests, including immunodiagnostic tests and nucleic acid tests. The essential component of an ECL technology-based system is the flow cell, which contains a magnet to separate the labeled substance from the sample being tested and a light detector to measure the electrochemiluminescence. The flow cell has been designed so that it can be incorporated into a variety of instruments, ranging from large central laboratory random access systems to small batch systems. BioVeris believes that the major features and benefits of ECL technology-based systems are: - Simplicity: uniform testing format reduces time and labor in performing a test or series of tests and permits complete automation of the testing process. - Flexibility: enables a single instrument to perform immunodiagnostic tests on large and small molecules and to perform nucleic acid tests, including in the form of DNA and RNA tests. - Cost: reduces the cost per test by minimizing the amount of expensive reagents needed and the number of steps required to prepare a sample for testing. - Speed: reduces time from test set-up to detection, producing rapid results and enabling high sample throughput. 142 - Sensitivity: allows detection of targeted biological substances at very low concentrations. - Consistency: provides highly-reproducible measurements. - Accuracy: provides results that are identical or close to the standard reference measurement. - Stability: extends the shelf-life of the reagent that contains the label used in testing and improves measurement accuracy. BioVeris believes that ECL technology is well suited for the continued development and sale of the M-SERIES family of instruments that can be used in all of BioVeris's target diagnostic markets. BioVeris believes the technology will permit virtually all immunodiagnostic and nucleic acid tests to be performed on similar instrumentation using the same detection method. ECL technology is well established in the market, evidenced by the fact that BioVeris's licensees have developed multiple product lines based on ECL technology and have sold or placed over 9,000 systems with customers worldwide which generate over $500 million in annual sales. Substantially all of these sales and placements have been made by Roche, one of the world's leading providers of clinical diagnostic products, which as a result of its ownership of IGEN upon completion of the merger will have a worldwide, non-exclusive, royalty-free license for BioVeris's ECL technology for use with certain defined systems and immunoassay methods for the clinical diagnostics market. BioVeris will not receive royalties or any other payments as a result of sales by Roche of products in accordance with this license. There can be no assurance that BioVeris will succeed in profitably developing, marketing and selling products based on ECL technology. IMPROVEMENTS FROM ROCHE During the development of its Elecsys product line, certain affiliates of Roche made improvements to intellectual property licensed to it by IGEN. These improvements are protected by patents, know-how and trade secrets and relate to: - Roche Diagnostics' ECL instruments and all aspects of ECL assays developed prior to the completion of the merger; - certain PCR technology; and - certain aspects of ECL technology and robotics used or developed prior to the completion of the merger. The license may be used without a field restriction (except as set forth in the next sentence) to develop, make, reproduce, modify, use, sell and otherwise commercially exploit any product or service based on ECL technology. In addition, BioVeris is licensed to use certain intellectual property rights of Hitachi High Technology Corporation and its affiliates only outside the field defined in the improvements license agreement to develop, make, reproduce, modify, use, sell and otherwise commercially exploit any product or services based on ECL technology. Subject to an exception, the field in the improvements license agreement is the same as the field in the license agreement. BioVeris may sublicense rights under both of these licenses to affiliates and third parties. The license does not permit BioVeris to develop, use, manufacture, sell or otherwise commercialize instruments based on ECL technology that meet certain specifications and use specific intellectual property, which are referred to in this proxy statement/prospectus as copycat instruments, in the field. In addition, the license does not permit BioVeris to develop, use, manufacture or sell ECL assays that contain labeling that make them useable on ECL instruments manufactured, sold or placed by Roche Diagnostics or its licenses or resellers, or on copycat instruments, in the field. For more information about the improvements license agreement, see "Commercial Agreements -- Improvements License Agreement." 143 PCR TECHNOLOGY PCR technology includes the amplification of specific nucleic acid sequences to a sufficient quantity of the nucleic acid sequence to permit detection and quantification. The process of nucleic acid amplification is commonly used for diagnostic procedures involving infectious agents, such as the AIDS virus, because of the need to detect the smallest amount of virus possible in the blood or other clinical samples. The PCR license agreements obtained by BioVeris will allow it to develop nucleic acid tests for several specified markets, including the human and animal in vitro diagnostics markets. BioVeris believes that nucleic acid tests are currently one of the fastest growing segments of the clinical diagnostics market and would complement BioVeris's immunodiagnostic product line. For more information about the PCR license agreements, see "Commercial Agreements -- PCR License Agreements." BioVeris does not currently sell, or have under development, any product based on the PCR technology being licensed from Roche. Roche has advised BioVeris that Applied Biosystems has notified Roche that one or more of the PCR licenses granted by certain Roche affiliates to BioVeris under the improvements license and the PCR license agreements may infringe exclusive rights to PCR technology held by, or other contract rights of, Applied Biosystems. Applied Biosystems has commenced litigation and arbitration against Roche regarding their respective rights relating to PCR technology. Certain Roche affiliates have made certain representations and provided certain warranties on their right to grant the licenses that have been granted to BioVeris, including representations and warranties that: the rights and licenses granted under the improvements license agreement and the performance by Roche Diagnostics of its obligations under the improvements license agreement will not conflict with any agreement, contract or other arrangement to which it is a party or by which it is bound; Roche Diagnostics has title to or license rights sufficient to grant such license rights granted under the improvements license agreement to BioVeris and its affiliates; Roche Diagnostics has not licensed or otherwise disposed of such licensed intellectual property rights in any manner that limits BioVeris's or its affiliates' exploitation of the licenses granted by Roche Diagnostics under the improvements license agreement; certain Roche affiliates have the full power and right to grant to BioVeris and its affiliates the licenses granted under the PCR license agreements; and the execution by certain Roche affiliates of the PCR license agreements will not constitute a breach or default under any contract, instrument or agreement to which such Roche affiliates or any of their affiliates are a party or by which such Roche affiliates or any of their affiliates are bound. Roche has advised IGEN that it believes that Applied Biosystems' allegations are without merit and intends to contest them vigorously. There are no assurances that BioVeris will not be named as a defendant in either of those actions or that Roche will prevail in the litigation and arbitration, or that the terms of any resolution or settlement of these proceedings will not be unfavorable to BioVeris. The results of these legal proceedings may limit, preclude or interfere with BioVeris's ability to exploit certain PCR technology licensed under the improvements license and PCR license agreements. See "Risk Factors -- Risks Relating to BioVeris and Its Business -- Because BioVeris intends to develop products that are based on patents and technology that it has licensed from others, the owners of those patents and technology might claim that products developed or sold by BioVeris violate those licenses. Additionally, a third party might object to a license that BioVeris holds or to the scope of the license granted to BioVeris." UNIT DOSE CARTRIDGE TECHNOLOGY BioVeris has a unique technology utilizing a disposable unit dose cartridge that BioVeris expects will be inexpensive to manufacture and contains all the reagents necessary to perform several different immunoassays on a single sample of blood from a patient. These reagents will be packaged so that they remain stable at room temperature for several months. This method of packaging reagents differs from the typical method of packaging reagents in a container that holds reagents for 100 to 200 tests for a single type of immunoassay and usually must be refrigerated. BioVeris has demonstrated that the test results using the unit dose cartridge are accurate and consistent with the results obtained using conventional instruments and kits used in central hospital laboratories. BioVeris believes the ease of use, room 144 temperature stability, accuracy and consistency of test results associated with this technology are important features for use in clinical point-of-care sites and biodefense applications. CENTRIFUGATION TECHNOLOGY BioVeris is seeking to incorporate into its M-SERIES family of products novel centrifugation technology that it is negotiating to acquire. BioVeris believes that this centrifugation technology will substantially enhance the ECL technology-based instruments that BioVeris intends to develop for clinical point-of-care sites. IGEN has funded feasibility studies for this centrifugation method that demonstrate that this centrifugation method can separate serum or plasma from whole blood in less than 60 seconds and in the process deliver the serum or plasma to a disposable unit dose cartridge. The serum or plasma has the same characteristics, specifically being free of white blood cells, red blood cells and platelets without rupturing these cells, as serum or plasma separated from whole blood using conventional methods. This novel centrifuge is small and BioVeris believes it can be incorporated into instruments that it is developing. The conventional process of separation involves a centrifugation step that takes 15 minutes. Following separation, a technician must manually remove the tube of blood from the centrifuge and pore off the serum or plasma into a test cup, which much be done using a biological safety cabinet to avoid the risk of infection. The novel centrifugation method being evaluated by BioVeris has the potential to avoid this safety hazard as well as the potential for advantages of speed, lower cost and ease of use. In a point-of-care setting this technology may also eliminate the delays associated with processing multiple samples. These delays occur when the technician performing the test has to wait, as long as 30 minutes, before loading more blood samples. 145 PRODUCTS AND MARKETS USING BIOVERIS TECHNOLOGY The following table summarizes the range of products that BioVeris has developed and is developing using ECL technology. BioVeris expects that its future products will incorporate other technology, which may include the improvements from Roche, PCR technology, unit dose cartridge technology and centrifugation technology. Sales of BioVeris's products represent approximately 94%, 93%, 93%, 91% and 65% of BioVeris's total revenues for the six months ended September 30, 2003 and 2002, fiscal 2003, 2002 and 2001, respectively.

In vitro diagnostic testing, which is the process of analyzing blood, urine and other samples to screen for, monitor and diagnose diseases and other medical conditions or to determine the chemical and microbiological constituents of the samples is one type of testing used by the clinical diagnostics market. BioVeris believes that ECL technology is best suited for the blood-based immunodiagnostic and nucleic acid testing segments of the clinical diagnostics market. The immunodiagnostic market segment was estimated to have had approximately $6 billion in annual sales in 2002. The nucleic acid testing market segment was estimated to have had approximately $1.5 billion in annual sales in 2001. Clinical diagnostic testing is performed in many locations, including testing by clinical reference laboratories, central hospital laboratories, and blood banks, as well as testing at clinical point-of-care sites. BioVeris's products for the clinical in vitro diagnostics market will generally require approval or clearance by the FDA prior to the marketing of the products, which BioVeris will seek in the appropriate stage of product development. See "Business -- Government Regulation -- Clinical Diagnostic Products" for a more detailed description of the government regulations to which BioVeris is subject in connection with products for the clinical in vitro diagnostics market. Point-of-Care Systems. Many diagnostic tests performed today involve a follow-up treatment decision by the physician, but the test and treatment process are usually decoupled. In most situations, samples of blood are drawn from a patient in the physician's office, emergency room or hospital room and sent to a laboratory at another location where the tests are performed. Test results are returned to the physician several hours or even several days later. BioVeris believes that there is demand among physicians, patients and third-party payers for clinical diagnostic products that reduce turnaround time by bringing laboratory testing closer to the patient and providing the physician with fast, quality and cost-effective results thereby permitting the physician to deliver prompt feedback to the patient. Most immunodiagnostic systems for clinical point-of-care sites have had limited market penetration because of the lengthy turnaround time for test results, the need for skilled labor to perform the tests and the high cost of the tests. BioVeris believes that the emergence of simple, more accurate and cost-effective diagnostic products is shifting the site of in vitro diagnostic testing from clinical reference laboratories and central hospital laboratories to alternative sites. BioVeris is developing a new instrument system, the M1-M clinical analyzer, to be a part of its M-SERIES family of instruments. BioVeris plans to integrate ECL, PCR, and other technologies into a small, expandable and modular system for the performance of immunodiagnostic and nucleic acid tests. The M1-M clinical analyzer is being designed for ease of use and the ability to provide fast results and is expected to be marketed to clinical point-of-care sites bringing laboratory testing closer to the patient thereby providing the associated benefits described above. BioVeris believes that the M1-M clinical analyzer may also be used in clinical reference laboratories, central hospital laboratories, and blood banks, which presently constitute the majority of the clinical diagnostics market. Using, among other things, improvements from certain affiliates of Roche, BioVeris plans to initially focus on the development and sale of cardiac assays that test for heart attack and congestive heart failure. The currently available cardiac tests for use at the clinical point-of-care sites are not as sensitive, accurate, or consistent as similar tests run in a central laboratory. BioVeris believes the M1-M can provide rapid turn-around time with the same levels of sensitivity, accuracy and consistency as a large instrument in a clinical reference laboratory or a hospital central laboratory. In addition, BioVeris intends to develop other immunoassays. BioVeris believes that its novel centrifugation method may be incorporated into the M1-M clinical analyzer to separate serum or plasma from whole blood, providing additional advantages to the use of the M1-M in clinical point-of-care sites. 147 BioVeris is exploring collaborative business arrangements to accelerate the development, manufacture and marketing of ECL technology-based products for clinical point-of-care applications. Clinical/Reference and Central Hospital Laboratory Systems. One of the significant applications of ECL technology is in large, highly automated clinical immunodiagnostic systems used in clinical reference laboratories, central hospital laboratories and blood banks. These laboratories currently constitute the vast majority of the clinical diagnostics market. To serve these laboratories, systems must be able to perform a wide variety of immunodiagnostic tests on a large number of samples consistently, cost effectively and quickly. Although BioVeris does not currently manufacture or sell products for the clinical diagnostics market, it intends to pursue opportunities for the clinical reference and central hospital laboratory market segment through collaborative arrangements. NON-CLINICAL DIAGNOSTICS Biodefense. BioVeris is commercializing products in the emerging market segment for biodefense, which involves the detection of bacteria, viruses and toxins that may pose a military or public health threat, as well as for the detection of foodborne and waterborne disease causing pathogens. BioVeris's currently available instruments include the BIOVERIS(TM) Detection System and M-SERIES M1-R Instrument. BioVeris believes there will be an increasing opportunity to use its products as a biodefense tool in governmental and military organizations around the world, as well as in public health, due to the early adoption of BioVeris products by key decision makers. BioVeris believes there currently are no dominant competitors. BioVeris expects that its nonclinical products for biodefense will generally not require the approval of a U.S. government agency prior to marketing of the products. See "Business -- Government Regulation -- Biodefense and Industrial Testing Products" for a more detailed description of the government regulations to which BioVeris is subject in connection with its products for biodefense. U.S. Army scientists at Fort Detrick, Maryland have developed ECL technology-based biological tests designed to measure specific agents and toxins in environmental samples. As part of the merger and related transactions, BioVeris expects to assume a contract between IGEN and the DOD pursuant to which the DOD may purchase these tests from IGEN. The DOD's legal counsel has reviewed and found acceptable from a legal perspective the form of novation agreement that BioVeris has prepared for transferring the DOD and other U.S. government contracts from IGEN to BioVeris. However, under applicable legal requirements the DOD consent to the transfer of the DOD contracts and other U.S. government contracts cannot be obtained until the restructuring is completed. Under the contract, the DOD may, at its option, make purchases of up to $23.0 million over a period of up to 48 months. As of September 30, 2003, the DOD had purchased approximately $1.7 million of products and, under the contract, may purchase up to a maximum of $7.0 million in the 12-month period ending June 2004. The tests being sold by BioVeris are based on ECL technology and do not depend on any technology licensed from Roche. The tests are used by various laboratories and field sites of the DOD, as well as other U.S. government agencies. For risks related to BioVeris's contracts with the government see "Risk Factors -- Risks Relating to Regulation and Government Contracts." BioVeris expects to continue to work with the DOD and other U.S. government agencies to expand the use of ECL technology-based products in a variety of homeland security and biodefense initiatives, including the development of reagents for the detection of biological agents, such as anthrax, staphylococcus enterotoxin B and botulinum, or toxins in environmental samples. The Automated Biological Agent Testing System program at the Edgewood Chemical and Biological Center, Aberdeen Proving Ground, in conjunction with BioVeris and Beckman Coulter, has integrated an M-SERIES instrument system with Beckman Coulter's SAGIAN(TM) and Biomek(R) FX lab automation systems to automate sample preparation and plate handling for ECL technology-based immunoassays. This program is designed for high throughput detection of biological agents and incorporates reagents that are 148 being manufactured by BioVeris. BioVeris is also engaged in early-stage initiatives for product development for this market including: - The Cooperative Research and Development Agreement with the U.S. Army Medical Research Institute of Infectious Diseases for the development of tests for the detection of biological toxins; - The development of a botulinum toxin test for the Centers for Disease Control and Prevention, or the CDC; - A contract with the DOD to develop assays for the detection of select agents in food; and - Integration of ECL technology into the Air Force biological testing program. Certain of IGEN's U.S. government contracts contain provisions that grant to the U.S. government a non-exclusive, non-transferable, irrevocable, paid-up license to use inventions made by IGEN in the course of performing such contracts, or have such inventions used by or on behalf of the U.S. government, for research or other government purposes. BioVeris will be subject to these provisions when it assumes these contracts and new U.S. government contracts entered into by BioVeris may also include similar provisions. See "Risk Factors -- Risks Relating to Regulation and Government Contracts." BioVeris is developing additional ECL technology-based products for the biodefense market. This includes the M-SERIES M1-HS (Homeland Security) Analyzer which is an enhanced model of the M-SERIES M1-R instrument designed to meet the specific needs of biodefense customers. The M1-HS analyzer is expected to be "ruggedized" to meet military specifications for an instrument to be deployed to the field with self-contained reagents and a portable carrying case. BioVeris also plans to develop an additional M-SERIES instrument that can be both miniaturized and "ruggedized" for use primarily by soldiers; "first responders," such as fire, police and emergency medical workers; medical workers; hospitals; food processors; field inspectors from the Environmental Protection Agency, or the EPA, the Department of Agriculture, or the Food and Drug Administration, or the FDA; and border patrol inspectors. BioVeris's presence in the biodefense market also provides the opportunity to sell products to other diagnostics markets. In addition to manufacturing specific tests for the detection of biological agents or toxins for the DOD, BioVeris has developed its own line of tests that can be sold to the pharmaceutical, biotechnology and food industries. These products include tests for the detection of Botulinum toxins A, B, E and F, Staphylococcal enterotoxins A and B, Ricin and anthrax. BioVeris intends to expand this product line to meet the demands of the market. BioVeris believes that tests developed for the biodefense field may also have utility in the clinical diagnostic markets by providing tests for patients exposed to biological agents or toxins. Industrial. BioVeris manufactures and sells a panel of tests for the detection of foodborne and waterborne disease-causing pathogens, such as E. coli O157, Salmonella, Campylobacter and Listeria. These tests are used as a quality control method for testing food and beverage products, such as meat used in hamburger, for bacteria that have caused numerous outbreaks of gastrointestinal and kidney-related disease worldwide. BioVeris expects that its products for industrial testing will generally not require the approval of a U.S. government agency prior to marketing of the products. See "Business -- Government Regulation -- Biodefense and Industrial Testing Products" for a more detailed description of the government regulations to which BioVeris is subject in connection with its products for industrial testing. Life Science. BioVeris provides products and services for the discovery and development of new drugs to the life science market. Its product development and marketing efforts center on two M-SERIES instruments -- the M384 and the M1-R instruments -- each of which build on the ECL technology-based applications provided by the M-SERIES systems and the BIOVERIS Detection System. BioVeris's products can be used by pharmaceutical and biotechnology companies, universities and other research organizations in most phases of drug discovery, including: - validating targets identified through genomics; 149 - screening of large numbers of compounds generated through combinatorial chemistry; - re-testing and optimization of lead compounds; and - clinical trial testing of drug candidates. After identifying disease targets and synthesizing chemical compounds, researchers attempt to find compounds that are drug candidates. This drug discovery process involves developing an assay to determine whether a particular compound has the desired effect on a target and then screening compounds using that assay. BioVeris believes that the need of pharmaceutical and biotechnology companies to rapidly identify therapeutic targets, screen thousands of compounds per day against those targets and then optimize the leads has created new opportunities for ECL technology-based systems in the pharmaceutical and biotechnology industry. BioVeris's M-SERIES instruments are compatible with multi-well microplates that are commonly used in drug discovery and development laboratories and can be fully integrated with many existing automation and robotic systems. These instruments were designed to enable researchers to test new biological targets against potential drug compounds with higher levels of accuracy and sensitivity. BioVeris believes they may also perform highly sensitive tests more quickly at a lower cost and this may permit a drug candidate to move more rapidly into the later stages of drug development, clinical trials and ultimately into the market. BioVeris believes that the sensitivity and accuracy of these M-SERIES systems create advantages over many competitive detection technologies. They permit the user to: - more quickly adapt the ECL technology to develop and then perform the specific, desired assays, compared to the longer periods required by other existing competing technologies; - reduce the use of rare components, such as proprietary compounds, antibodies or clinical trial samples, that must be used to run assays; and - have more confidence in the results the tests produce. BioVeris's expertise in developing assays allows it to assist customers in determining whether a proposed assay is feasible and to assist with the development and performance of assays that comply fully with the FDA's Good Manufacturing Practices. BioVeris's M-SERIES life science customers include many of the major pharmaceutical and biotechnology companies in the United States and Europe. In addition to the M-SERIES instruments BioVeris sells or leases, it typically receives commitments from customers for purchases of proprietary reagents. BioVeris markets the M-SERIES product family directly through its own sales, marketing and applications teams. Instrument systems originally designed for the life science market are now being used in biodefense and may be used in the clinical diagnostics market as well. BioVeris believes that its presence in the life science market provides it with the opportunity to identify novel tests that may have utility in the clinical diagnostics market. While continuing to support its existing bio-pharmaceutical and academic customers, BioVeris may selectively pursue other commercial opportunities in the life science market in support of its overall corporate strategy. BioVeris's products that will be sold only for research use in the life science market generally do not require the approval of a U.S. government agency prior to marketing of the products. See "Business -- Government Regulation -- Life Science Research Products" for a more detailed description of the government regulations to which BioVeris is subject in connection with its products for the life science market. COLLABORATIONS AND LICENSE ARRANGEMENTS BioVeris expects to explore and negotiate collaborative business arrangements to accelerate the development, manufacture and marketing of ECL technology-based products, in particular into the clinical 150 diagnostics market. In addition, BioVeris has license arrangements with Roche Diagnostics, bioMerieux Eisai and MSD. ROCHE DIAGNOSTICS As a result of Roche's ownership of IGEN, upon completion of the merger, an affiliate of Roche, one of the world's leading providers of clinical diagnostic products, will have a worldwide, royalty-free, non-exclusive license to develop, make, reproduce, modify, use, sell and otherwise commercially exploit certain clinical immunoassay instruments and assays using defined ECL technology owned by BioVeris in the human in vitro diagnostics field, including the continued sale and further development of its Elecsys products. For a further description of this license, see "Commercial Agreements -- License Agreement." BioVeris will not receive royalties or other payments as a result of product sales by Roche in accordance with the license agreement. Under the improvements license agreement effective simultaneously with the completion of the merger, BioVeris will have a worldwide, non-exclusive, fully-paid, royalty-free, perpetual license under certain patents covering and technologies based on: - Roche Diagnostics' ECL instruments and all aspects of ECL assays developed prior to the completion of the merger; - certain PCR technology; or - all aspects of ECL technology and robotics that, prior to the completion of the merger, Roche Diagnostics or any of its affiliates used or developed to be used in performing ECL testing (other than specific antibodies, antigens and reagents). In addition, BioVeris is licensed to use certain intellectual property rights of Hitachi High Technology Corporation and its affiliates only outside the field defined in the improvements license agreement to develop, make, reproduce, modify, use, sell and otherwise commercially exploit any product or service based on ECL technology. Roche has advised BioVeris that Applied Biosystems has notified Roche that one or more of the PCR licenses granted by certain Roche affiliates to BioVeris under the improvements license agreement and the PCR license agreements may infringe exclusive rights to PCR technology held by, or other contract rights of, Applied Biosystems. Applied Biosystems has commenced litigation and arbitration against Roche regarding their respective rights relating to PCR technology. Certain Roche affiliates have made certain representations and provided certain warranties on their right to grant the licenses that have been granted to BioVeris, including representations and warranties that: the rights and licenses granted under the improvements license agreement and the performance by Roche Diagnostics of its obligations under the improvements license agreement will not conflict with any agreement, contract or other arrangement to which it is a party or by which it is bound; Roche Diagnostics has title to or license rights sufficient to grant such license rights granted under the improvements license agreement to BioVeris and its affiliates; Roche Diagnostics has not licensed or otherwise disposed of such licensed intellectual property rights in any manner that limits BioVeris's or its affiliates' exploitation of the licenses granted by Roche Diagnostics under the improvements license agreement; certain Roche affiliates have the full power and right to grant to BioVeris and its affiliates the licenses granted under the PCR license agreements; and the execution by certain Roche affiliates of the PCR license agreements will not constitute a breach or default under any contract, instrument or agreement to which such Roche affiliates or any of their affiliates are a party or by which such Roche affiliates or any of their affiliates are bound. Roche has advised IGEN that it believes that Applied Biosystems' allegations are without merit and intends to contest them vigorously. There are no assurances that BioVeris will not be named as a defendant in either of those actions or that Roche will prevail in the litigation and arbitration, or that the terms of any resolution or settlement of these proceedings will not be unfavorable to BioVeris. The results of these legal proceedings may limit, preclude or interfere with BioVeris's ability to exploit certain PCR technology licensed under the improvements license agreement and PCR license agreements. See "Risk Factors -- Risks Relating to BioVeris and Its 151 Business -- Because BioVeris intends to develop products that are based on patents and technology that it has licensed from others, the owners of those patents and technology might claim that products developed or sold by BioVeris violate those licenses. Additionally, a third party might object to a license that BioVeris holds or to the scope of the license granted to BioVeris." For a further description of this license, see "Commercial Agreements -- Improvements License Agreement." BIOMERIEUX bioMerieux has a license from BioVeris for the development and worldwide development, use, manufacture and sale of ECL technology-based nucleic acid test systems on a co-exclusive basis for certain segments of the clinical diagnostics market and on a non-exclusive basis for certain segments of the life science market. bioMerieux specializes in products for central hospital laboratories and blood banks and has incorporated its proprietary nucleic acid sequence-based amplification technology and ECL technology into its NucliSens line of diagnostic virology products, which are marketed with test kits for the detection of HIV-1 RNA and CMV (cytomegalovirus). The agreement with bioMerieux extends until the expiration of the patents BioVeris licenses to bioMerieux, and BioVeris receives royalty payments from bioMerieux on the relevant product sales by bioMerieux. EISAI Eisai, a leading Japanese pharmaceutical company, has a license to manufacture and market a class of ECL technology-based diagnostic systems for the clinical diagnostics market in Japan on a non-exclusive basis. Eisai introduced its first ECL-based product under the trade name Picolumi in 1997. BioVeris receives royalties on the relevant product sales by Eisai. The agreement with Eisai extends until the later of May 10, 2010, and the expiration of the patents BioVeris licenses to Eisai. Eisai is obligated to make royalty payments to BioVeris at a reduced royalty rate for a period of seven years after expiration of the agreement. MSD As part of the restructuring, BioVeris will assume IGEN's interest in MSD, a joint venture formed in 1995 by IGEN and MST, which is a company established and wholly-owned by Mr. Jacob Wohlstadter, a son of BioVeris's and IGEN's chairman and chief executive officer. MSD develops, manufactures, markets and sells products utilizing a combination of MST's multi-array technology and BioVeris's technology. MSD manufactures, markets and sells instrument systems, including the Sector HTS and the Sector PR, which combine MST's multi-array technology and IGEN's ECL technology. The Sector HTS is an ultra high throughput drug discovery system engineered for applications such as high throughput screening and large-scale proteomics. The Sector PR is a smaller system designed for benchtop applications such as assay development, research in therapeutic areas, cellular biology and medium throughput screening. MSD also manufactures and markets a line of its own reagents, assays and plates that are used on these MSD systems. MSD commenced product sales in October 2002 and, during fiscal 2003, MSD had product sales of $3.2 million and a net loss of $18.2 million. The MSD joint venture agreement will expire upon completion of the merger and MSD and MST have the right to purchase IGEN's or BioVeris's, as the case may be, interest in MSD for a purchase price equal to fair market value (determined in accordance with the procedures set forth in the MSD agreements, which includes third-party appraisal if the parties are unable to agree on fair market value) minus a discount factor. If MSD or MST exercises this right, it will be required to pay BioVeris the outstanding purchase price plus simple (cumulated, not compounded) interest at the fixed annual rate of 0.5% over the prime rate in effect on the date that MSD or MST, as the case may be, elects to purchase the interests. The purchase price is payable over time in installments equal to the sum of 5% of MSD net sales, as determined in accordance with the MSD agreements, and 20% of the net proceeds realized by 152 MSD from the sale of its debt or equity securities in any third-party financing after the date of the sale of BioVeris's interest in MSD. Nevertheless, following the expiration of the MSD joint venture agreement, many of the licenses and other arrangements with MSD and MST assigned to BioVeris will continue indefinitely. For a more complete description of the MSD agreements and IGEN's relationship with MSD, see "Certain Relationships and Related Party Transactions" and "Management's Discussion and Analysis of Financial Condition and Results of Operations." INTELLECTUAL PROPERTY BioVeris pursues a policy of seeking patent protection to preserve its technology and its right to capitalize on the results of its research and development activities and, to the extent it may be necessary or advisable, to exclude others from appropriating its technology. BioVeris will also rely on trade secrets, know how, continuing technological innovations and licensing opportunities to develop and maintain its competitive position. BioVeris intends to prosecute and defend its intellectual property, including its patents, trade secrets and know-how. BioVeris plans to regularly search for third-party patents in its fields of endeavor, both to shape its patent strategy as effectively as possible and to identify possible collaborations and licensing opportunities. After the restructuring, BioVeris expects to own approximately 69 issued U.S. patents, and approximately 24 pending U.S. patent applications in the diagnostics field. Additionally, BioVeris expects to own approximately 145 granted foreign patents and approximately 70 pending foreign patent applications in the diagnostics field. These patents and patents applications are important to BioVeris's business and cover various aspects of ECL technology and products, as well as the methods for their production and use. The pending patent applications in the diagnostics field may not be granted and others may challenge BioVeris's patents. BioVeris's ECL patents will begin to expire in 2005; however, patent coverage for ECL technology will continue through 2018. BioVeris plans to continue to protect its technology with new patent filings, which could further extend its patent coverage. Additionally, at the same time, BioVeris expects to own patents and patent applications outside of the diagnostics field. More specifically, BioVeris will own approximately 35 issued U.S. patents, approximately 10 pending U.S. patent applications, approximately 100 non-U.S. patents and approximately 30 patent applications in the fields of catalytic antibodies and other novel biocatalysts, molecular displays and hybridoma screening, and jointly own one pending U.S. patent application in the field of therapeutic compounds. The pending patent applications outside the diagnostics field may not be granted and others may challenge BioVeris's patents outside the diagnostics field. BioVeris's business could be harmed if it loses the patent protection currently enjoyed by IGEN or if pending patents are not issued to BioVeris. GOVERNMENT REGULATION The research and development, manufacturing, marketing, sale and distribution of both existing and future products based on ECL technology are subject to comprehensive government regulation. Government regulation by various Federal, state, and local agencies, which includes detailed inspection of, and controls over, research and laboratory procedures, safety, clinical investigations, manufacturing, marketing, sampling, labeling, distribution, record keeping, storage and disposal practices, substantially increases the time, difficulty and costs incurred in obtaining and maintaining the clearance or approval to market newly developed and existing products. In particular, government regulatory actions can result in, among other things, delays in the release of BioVeris's and its licensees' products, injunction, seizure or recall of BioVeris's or its licensees' products, suspension or revocation of the authority necessary for their production and sale, and other civil or criminal sanctions, including monetary penalties that could be substantial. 153 International sales of products by BioVeris and its licensees will also be subject to a significant degree of government regulation, including international standards (such as those set by the International Organization for Standards), European Union directives and other country-specific rules and regulations. For example, many countries, directly or indirectly through reimbursement limitations, control the cost of most clinical diagnostic products. Furthermore, many developing countries limit the importation of raw materials and finished products. International regulations may also have an impact on U.S. regulations. In addition, the FDA regulates the export of products from the United States. BIODEFENSE AND INDUSTRIAL TESTING PRODUCTS BioVeris's biodefense products will be subject to stringent Federal, state, local and foreign laws, regulations and policies governing their manufacture, storage, sale, distribution and export. In addition, the U.S. government has adopted, and is expected to continue to adopt, laws, regulations and rules governing the research, development, procurement and handling of pathogens that may be used in a bioterrorist attack or other agents that may cause a public health emergency and to permit government inspection and oversight of facilities engaged in the research, development, manufacture or sale of select agents. Under several statutes recently enacted, the Department of Homeland Security, FDA, Department of Commerce and various other regulatory authorities have been charged with establishing and implementing programs designed to enhance the security of food and water supplies, as well as the environment, from terrorist attacks. These legislative initiatives include recordkeeping, registration, notification, import, export, manufacturing and various other compliance measures. This is a rapidly evolving regulatory landscape and many of the possible rules and regulations have not yet been proposed or adopted. BioVeris may be required to incur significant costs to comply with such laws and regulations in the future, and such laws or regulations may have a material adverse effect upon its ability to do business. LIFE SCIENCE RESEARCH PRODUCTS BioVeris's products that will be sold for life science research use only, including the M-SERIES instruments used in the life science market, must be properly labeled as "for research use only -- not for use in diagnostic procedures", as required by the FDA, but do not generally require FDA approval prior to marketing. Research does not include clinical investigations and is narrowly defined by the FDA to apply to the early development of product concepts. The FDA has begun to impose new distribution requirements and procedures on companies selling research use only products, such as the requirement that the seller receive specified certifications from its customers as to the customers' intended use of the product. BioVeris expects that the FDA will develop additional restrictions of this nature some of which may adversely affect BioVeris. CLINICAL DIAGNOSTIC PRODUCTS The FDA, and other Federal, state, local, and foreign authorities, regulate, among other things, the development, clinical testing, manufacture, packaging, labeling, storage, distribution and promotion of medical devices, including products intended for clinical diagnostic purposes. The FDA imposes specific requirements on the conduct of clinical studies and requires approval of the study by an institutional review board and, in some cases, by the FDA, depending upon the product and its use. Before a new device can be introduced into the market, the manufacturer must generally obtain marketing clearance through a section 510(k) pre-market notification or approval through a pre-market approval application. The testing, preparation of necessary applications and processing of those applications by the FDA is expensive and time consuming. BioVeris's and its licensees' clinical diagnostic products will be regulated as medical devices. Significant difficulties or costs may be encountered to obtain FDA clearances or approvals and that could delay or preclude BioVeris or its licensees from marketing products for clinical diagnostic purposes. Furthermore the FDA may request additional data following the original submission. Delays imposed by the governmental review process may materially reduce the period during which BioVeris or its licensees will have the exclusive right to exploit BioVeris's products or technologies. 154 The FDA will clear a device under section 510(k) if the submitted information establishes that the proposed device is "substantially equivalent" to a legally marketed class I or II medical device, or to a class III medical device for which the FDA has not yet called for a pre-market approval application. Commercial distribution can begin only after the FDA issues an order that the device is substantially equivalent to a device that is legally marketed and not subject to a pre-market approval requirement. The FDA may determine that a proposed device is not substantially equivalent to a legally marketed device, in which case a pre-market approval will be required to market the device, unless additional information can be submitted to support a substantial equivalence determination, or the FDA, pursuant to a timely request, makes a risk-based determination that a device that is not substantially equivalent device can be classified into class I or II. An FDA request for additional data could require that clinical studies of the device's safety and effectiveness be performed. Clearance, if obtained, may be conditioned on labeling restrictions or conducting a lengthy postmarket surveillance study. A pre-market approval application must be filed and approved before a device can be marketed if a proposed device is not substantially equivalent to a legally marketed device, as discussed above, or if it is a class III device that was in commercial distribution prior to May 28, 1976, for which the FDA has called for pre-market approval. A pre-market approval application must be supported by valid scientific evidence, which typically includes extensive pre-clinical data and well controlled or partially controlled clinical trials, to demonstrate the safety and effectiveness of the device. Obtaining approval can take several years and approval may be conditioned on, among other things, substantial restrictions on indications for use and the conduct of postmarket surveillance studies. Generally, the pre-market approval process requires much more extensive pre-filing testing than does the section 510(k) pre-market notification procedure and involves a significantly longer FDA review after the date of filing. In responding to a pre-market approval application, the FDA may grant marketing approval, may request additional information, may set restrictive limits on claims for use or may deny the application altogether. After the pre-market clearance or approval for the medical device has been received, it may still be withdrawn if compliance with regulatory standards is not maintained or if problems occur after the device reaches the market. The FDA may require post-market surveillance programs to monitor the effect of medical devices that have been sold, and has the power to prevent or limit further marketing of medical devices based on the results of these post-marketing programs. In addition, the FDA's medical device reporting regulation requires reports to the FDA whenever information reasonably suggests that a marketed device may have caused or contributed to death or serious injury, or when a device malfunctions and if the malfunction were to recur, the device would be likely to cause or contribute to a death or a serious injury. In addition to obtaining FDA approval for each medical device, under the pre-market approval application procedures, BioVeris or its licensees must seek FDA approval of their manufacturing facilities and procedures. The FDA will also inspect clinical diagnostics companies on a routine basis for regulatory compliance with its Good Manufacturing Practices regardless of whether the product was cleared under section 510(k) or approved under pre-market approval. BioVeris's and its licensees' clinical diagnostic products will be affected by the Clinical Laboratory Improvement Amendments of 1988, which is intended to insure the quality and reliability of medical testing and may have the effect of discouraging, or increasing the cost of, clinical diagnostic testing. The regulations establish numerous requirements applicable to clinical diagnostics. Under these regulations, the specific requirements that a laboratory must meet depend upon the complexity of the tests performed by the laboratory. Under the clinical laboratory improvement regulations, all laboratories performing moderately complex or highly complex tests will be required to comply with stringent standards and requirements. Because the regulations' interpretation is uncertain, it is possible that certain of BioVeris's or its licensees' products may be categorized as highly complex tests, in which case penetration of the point-of-care market would be reduced because not all laboratories would meet the standards required to conduct such tests. 155 In addition, future changes in regulations or interpretations made by the U.S. Department of Health and Human Services, FDA, Centers for Medicare & Medicaid Services or other regulatory bodies may adversely affect BioVeris and its licensees. In addition to the foregoing, BioVeris will be, and its licensees are, subject to numerous Federal, state and local laws and regulations relating to such matters as safe working conditions, laboratory and manufacturing practices, fire hazard control, and environmental protection, including disposal of hazardous or potentially hazardous substances. BioVeris does not expect compliance with these laws and regulations to have a material effect on its financial results, capital requirements or competitive position, and BioVeris has no plans for material capital expenditures relating to such matters. However, BioVeris and its licensees may be required to incur significant costs to comply with such laws and regulations in the future, and such laws or regulations may have a material adverse effect upon BioVeris's and its licensees' ability to do business. Sales of BioVeris's and its licensees' products outside the U.S. are also subject to extensive regulatory requirements, which vary widely from country to country. The time required to obtain the necessary approvals may be longer or shorter than that required for FDA clearance or approval. GOVERNMENT CONTRACTS AND REGULATION The contracts with U.S. and foreign government agencies and departments that BioVeris expects to assume as part of the restructuring will require that BioVeris comply with numerous regulations, rules and policies, including those governing procedures for soliciting, awarding and funding government contracts. In addition, BioVeris will be required to comply with numerous ongoing obligations following the award of a government contract, including those relating to record keeping, workplace compliance, third-party contracting, and disclosure of information. Failure to comply with these requirements may lead to a denial of a contract award, a challenge to a previously awarded contract, attempts by the U.S. government to terminate a contract, and restrictions on a company's ability to participate in future bids to secure government contracts. In addition, BioVeris is required to obtain certain security clearance certifications and comply with security clearance standards and requirements, including those affecting personnel and facilities. Sales of certain of BioVeris's products to international government agencies may be subject to local government regulations and procurement policies and practices, as well as to regulations relating to import-export control, including prior notification of, and pre-clearance for, export of certain goods having military applications. ENVIRONMENTAL REGULATION BioVeris's operations will be subject to stringent foreign, Federal, state and local laws, rules and regulations relating to the protection of the environment, including those governing the use, handling and disposal of hazardous, radioactive and infectious materials and wastes, the discharge of pollutants into the air and water and the cleanup of contaminated sites. Some of BioVeris's operations will require permits, and these permits will be subject to modification, renewal and revocation by issuing authorities. Although BioVeris believes that it will be in compliance with these laws and regulations in all material respects, BioVeris may be required to incur significant costs to maintain or achieve compliance if additional or stricter environmental and health and safety requirements are imposed in the future or in the event of any noncompliance at BioVeris's facilities. REIMBURSEMENT Third-party payers, such as governmental programs and private insurance plans, can indirectly affect the pricing or the relative attractiveness of BioVeris products by regulating the maximum amount of reimbursement they will provide for diagnostic testing services. In recent years, healthcare costs have risen substantially, and third-party payers have come under increasing pressure to reduce such costs. 156 In this regard, the Federal government, in an effort to reduce healthcare costs, may take actions that may involve reductions in reimbursement rates. If the reimbursement amounts for diagnostic testing services are decreased in the future, it may decrease the amount which physicians, clinical laboratories and hospitals are able to charge patients for such services and consequently the price BioVeris and its collaborators will be able to charge for their products. COMPETITION BioVeris competes in the non-clinical diagnostics markets, including biodefense, industrial and life science markets with its diagnostic instruments, reagents and assays and expects to compete in the clinical diagnostics market. BioVeris believes that the principal competitive factors in these markets are: - the time required to run tests with the product; - the level of sensitivity, accuracy and consistency of the product; - the relative ease of use of the product; - the quality of support and services for the product; - flexibility and expandability of the product; - product time-to-market; - product safety; - market acceptance of product; and - product price. Although BioVeris believes that it competes favorably with respect to the above factors, competition in the diagnostics market is intense and BioVeris does not hold a leading competitive position in any of the markets in which it competes. BioVeris expects to compete with a number of domestic and international companies, including Roche, Johnson & Johnson, Abbott Laboratories, Bayer, Biosite Incorporated and Dade Behring, Inc. Many of BioVeris's competitors now have and in the future may continue to have access to greater resources than BioVeris does and, therefore, may be better equipped to develop, manufacture, market and sell its products. These companies may develop and introduce products and processes competitive with or superior to BioVeris's. In addition, BioVeris will directly compete against its current and future licensees, including bioMerieux, Roche and MSD. PROPERTIES BioVeris's principal administrative, marketing, manufacturing and research and development facilities consist of approximately 165,000 square feet located in five buildings in Gaithersburg, Maryland. BioVeris has an additional 21,000 square feet of leased research and development, sales and office facilities in McLean, Virginia; San Diego, California; New York, New York; the District of Columbia; and Oxfordshire, England. BioVeris's leases expire at various times from 2005 through 2010. BioVeris believes that current facilities should be adequate for immediate business requirements but additional facilities may be required if BioVeris successfully expands its business operations. BioVeris is evaluating new facilities for development, manufacturing and other corporate uses and is in negotiations to secure new space, which, if concluded, would result in additional facilities costs. MANUFACTURING BioVeris's current commercial manufacturing operations consist of the manufacture of the M-SERIES family of products and reagents, biodefense and industrial testing products, and cell culture research biologicals. BioVeris operates a qualified Good Manufacturing Practices and ISO 9001 facility. BioVeris uses a variety of suppliers and believes that it does not depend on any supplier that cannot be 157 replaced in the ordinary course of business. Any changes in source of supply may require additional engineering or technical development, with costs and delays that could be significant, to ensure consistent and acceptable performance of the products. BioVeris does not manufacture any clinical diagnostic products. BioVeris is presently evaluating plans for future manufacturing of its clinical diagnostic products. These plans may include direct and third-party manufacturing. Negotiations are ongoing with a world leader in mobile electronics and systems technology to manufacture one of BioVeris's instruments. There can be no assurance that these negotiations will result in an agreement with such manufacturer on terms favorable to BioVeris, if at all or that such manufacturer will be successful in manufacturing BioVeris's instruments. See "Risk Factors -- Risks Relating to BioVeris and Its Business -- BioVeris has limited manufacturing experience, which puts it at a competitive disadvantage and could have a material adverse effect on BioVeris's business, financial condition and revenue," "Risk Factors -- Risks Relating to BioVeris and Its Business -- BioVeris has limited manufacturing facilities for its products and BioVeris may not find additional facilities suitable for future growth, which could materially adversely affect its business and prospects" and "Risk Factors -- Risks Relating to BioVeris and Its Business -- BioVeris depends on a limited number of suppliers for materials used in the manufacturing of its products, and any interruption in the supply of those materials could hamper its ability to manufacture products and meet customer orders." SALES AND MARKETING BioVeris also maintains a direct sales and marketing group in the United States and Europe that consists of approximately 30 people. BioVeris's direct sales group focuses on sales of the M-SERIES family of products and the BIOVERIS(TM) Detection System, together with reagents and services, to various government agencies in the biodefense market, food and beverage producers and contract testing laboratories in the industrial market and other potential customers in the life science market. In addition to BioVeris's direct and indirect sales and marketing efforts, BioVeris's licensees and collaborators also conduct sales and marketing of BioVeris's products. See "Description of the BioVeris Business -- Collaborations and License Arrangements." BioVeris is evaluating plans for the marketing and sale of its products currently in development. BioVeris may seek to market and sell a portion of its products indirectly through distributors who sell products that complement BioVeris's products. HUMAN RESOURCES As of November 30, 2003, BioVeris and its subsidiaries employed 303 individuals, of whom 221 were engaged in research, product development, manufacturing and operations support, and 82 in marketing, sales and applications support and general administration. Of BioVeris's employees, 41 have Ph.D. degrees. A significant number of BioVeris's management and professional employees have had prior experience with pharmaceutical, biotechnology, diagnostic or medical products, computer software or electronics companies. None of BioVeris's employees is covered by a collective bargaining agreement, and management considers relations with its employees to be satisfactory. Pursuant to the restructuring agreement, effective January 1, 2004 all IGEN employees (other than those who have accepted employment with MSD as described below) will become employees of BioVeris or its subsidiaries. As required under the restructuring agreement, the BioVeris offer of employment to the IGEN employees was - for those employees who are participants in the IGEN termination protection program, for a "qualifying position," as defined in the IGEN termination protection program, and - for the employees who are not participants in the IGEN termination protection program, for substantially comparable employment, including responsibility, compensation and benefits. 158 Accordingly, as of January 1, 2004, BioVeris will have 249 employees, of whom 174 will be research, product development, manufacturing and operations support, and 75 in marketing, sales and applications support and general administration. Of these employees, 20 have Ph.D. degrees. In connection with the transfer of IGEN employees to BioVeris, the BioVeris board of directors has approved the grant, subject to the approval of the BioVeris 2003 stock incentive plan by IGEN stockholders and the completion of the merger, to BioVeris employees of options to purchase 100 shares of BioVeris common stock. Each option will have an exercise price equal to fair market value on the date of grant and will vest in full on the first anniversary of the date that the merger is completed. In addition, during December 2003, 54 IGEN employees were offered and accepted employment at MSD commencing on January 1, 2004. This includes 47 employees engaged in research, product development, manufacturing and operations support and approximately seven in general administration. The employees who were offered and accepted employment with MSD were primarily those that allocated more than a majority of their time during the past year to MSD projects and matters and the cost for whom were included in the value of BioVeris's in-kind contributions to MSD. The employees that have accepted employment with MSD include a significant percentage of BioVeris's software development, information technologies and intellectual property departments, including the heads of those departments. In connection with the transfer of employees from IGEN to MSD, IGEN accelerated as of January 1, 2004 the vesting of all unvested stock options held by such employees who accepted the offer of employment with MSD. Upon completion of the merger, all outstanding options granted under IGEN's stock option plans, including unvested options, will be canceled and the holder of any such options will have the right to receive for each share covered by such option cash from Roche equal to the excess of $47.25 over the exercise price of such option (without interest) and one share of BioVeris common stock. For a further description of the effect of the acceleration and cancelation of IGEN stock options, see "Management's Discussion and Analysis of Financial Condition and Results of Operations." Following completion of the merger, BioVeris does not expect that it will have any further costs or obligations directly attributable to the transfer of employees from IGEN to BioVeris or MSD, as the case may be. The ability to maintain BioVeris's competitive position will depend, in part, upon its continued ability to attract and retain qualified scientific, technical and managerial personnel. Competition for such personnel is intense. LEGAL PROCEEDINGS BioVeris is involved, from time to time, in various routine legal proceedings arising out of the normal and ordinary operation of its business, which it does not anticipate will have a material adverse impact on its business, financial condition, results of operations or cash flows. However, BioVeris may in the future be involved in litigation relating to its business, products or intellectual property, which could adversely affect BioVeris's prospects or impair its financial resources. See "Risk Factors -- Risks Relating to BioVeris and Its Business -- The success of BioVeris's business depends on patents that will expire over time and that must be actively pursued, obtained, maintained and protected. BioVeris's business could be harmed if it has future disagreements with Roche over the scope of the license agreement," "Risk Factors -- Risks Relating to BioVeris and Its Business -- BioVeris's business could be harmed if it infringes, or is alleged to have infringed, the intellectual property of others" and "Risk Factors -- Risks Relating to the Industry -- BioVeris is exposed to product liability risks that, if not adequately covered by insurance, may have a material adverse effect on its financial condition." 159 SEASONAL ASPECTS, BACKLOG AND RENEGOTIATION There are no significant seasonal aspects to BioVeris's business. Orders for BioVeris's products will be filled on a current basis, and order backlog is not expected to be material to BioVeris's business. A material portion of BioVeris's business is expected to be subject to contracts that may be terminated at the election of the government. In the event BioVeris's biodefense business expands, the portion of BioVeris's business subject to contracts that may be terminated at the election of the government is likely to expand. For a further description of risks related to BioVeris's contracts with the government, see "Risk Factors -- Risks Relating to Regulation and Government Contracts." OPERATING SEGMENT BioVeris currently operates in one business segment. BioVeris is currently engaged in the development, manufacturing and marketing of diagnostic products for the detection and measurement of biological and chemical substances. GEOGRAPHIC SEGMENTS BioVeris does not believe it has material risks relating to its foreign business. 160 MANAGEMENT DIRECTORS AND EXECUTIVE OFFICERS The following table sets forth certain available information regarding BioVeris's directors and executive officers.

CORPORATE GOVERNANCE AND COMMITTEES OF THE BOARD OF DIRECTORS The BioVeris board of directors acts as nominating committee for selecting nominees for election as directors. BioVeris's by-laws permit stockholders eligible to vote for the election of directors at the Annual Meeting to make nominations for directors, but only if such nominations are made pursuant to timely notice in writing to its Secretary. BioVeris's by-laws also permit stockholders to propose other business brought before an annual meeting, provided that such proposals are made pursuant to timely notice to the 162 Secretary. To be timely, notice must generally be delivered to BioVeris's principal executive offices no later than the close of business on the 120th calendar day prior to the first anniversary of the preceding year's annual meeting. See "Comparison of Rights of Common Stockholders of BioVeris and IGEN -- Notice of Stockholder Actions -- BioVeris." The BioVeris board of directors will have an audit committee, an executive compensation committee, a non-officer stock option committee and a JVOC. The BioVeris board of directors does not have a standing nominating committee. The audit committee will review BioVeris's auditing, accounting, financial reporting and internal control functions and makes recommendations to the BioVeris board of directors for the selection of the independent auditor. In discharging its duties, the committee will review and approve the scope of the annual audit and the independent auditor's fees; meet independently with BioVeris's internal accounting staff, independent auditor and senior management; and review the general scope of BioVeris's accounting, financial reporting, annual audit and internal audit program, and matters relating to internal control systems as well as the results of the annual audit. The audit committee will have three members: Messrs. Salsmans, Sistermans and Rees, each of whom is independent as defined in Rule 4200(a)(15) of the National Association of Securities Dealers' marketplace rules. The BioVeris board of directors has adopted a written charter for the audit committee. The written charter for the audit committee provides that the audit committee will review and approve all related party transactions; provide oversight for the BioVeris board of directors with respect to related party transactions, including a review with the independent auditor of any new or ongoing related party transactions; and advise the BioVeris board of directors with respect to BioVeris policies and procedures regarding compliance with the related party transaction policy. BioVeris intends to establish a policy statement on conflicts of interest for employees, officers, directors and members of any outside advisory board of BioVeris and a policy statement on related party transactions, which provides that all material related party transactions are subject to the review and approval of the audit committee (excluding any director who may be an interested party). Any transaction between BioVeris and Mr. Samuel Wohlstadter (or any other officer or director), or any transaction between BioVeris and any of the related companies, will be subject to review and approval by the audit committee. The executive compensation committee will be responsible for establishing BioVeris's compensation programs for executive officers and making determinations concerning executive salaries and incentive compensation, awards stock options to executive officers under BioVeris's 2003 stock incentive plan and otherwise determining executive officer compensation levels and performing such other functions regarding compensation as the BioVeris board of directors may delegate. The executive compensation committee will have two members: Messrs. Salsmans and Sistermans, both of whom are "non-employee directors" and "outside directors" as defined in the rules promulgated by the Securities and Exchange Commission and Section 162(m) of the Internal Revenue Code. The BioVeris board of directors has established a written charter for the executive compensation committee. The non-officer stock option committee will have authority to grant stock options to persons who are not, at the time of the grant of the option, executive officers subject to Section 16 of the Securities Exchange Act of 1934, as amended. The non-officer stock option committee has two members: Mr. Samuel Wohlstadter and Dr. Massey. The JVOC will have the authority and responsibility for overseeing and monitoring BioVeris's participation in MSD, a joint venture with MST; ensuring BioVeris's compliance with its obligations to MSD; establishing its position on issues arising under current agreements with MSD, MST and Mr. Jacob Wohlstadter; negotiating amendments to existing agreements or any new agreements with MSD, MST or Mr. Jacob Wohlstadter, as the committee deems necessary; and providing instructions and direction to BioVeris's designee to the board of managers of MSD. The JVOC must consist of at least two independent directors appointed by the BioVeris board of directors. The current members of the JVOC 163 are: Messrs. Salsmans, Sistermans and Rees, each of whom is independent as defined in Rule 4200(a)(15) of the National Association of Securities Dealers' marketplace rules and Section 10A of the Securities Exchange Act of 1934, as amended. The BioVeris board of directors has established a written charter for the JVOC. COMPENSATION OF DIRECTORS Set forth below is information regarding the compensation of BioVeris's directors while serving as directors of IGEN in fiscal 2003. Each non-employee director of IGEN received an attendance fee of $1,000 for each meeting of the IGEN board of directors that he attended. In fiscal 2003, the aggregate compensation paid to non-employee directors (directors other than Mr. Wohlstadter and Dr. Massey) was $33,000. Effective May 2003 each non-employee director of IGEN: - receives an annual retainer of $10,000 and an attendance fee of $1,000 for each meeting of the IGEN board of directors that he attends; - that serves on the JVOC or audit committee receives an additional annual retainer of $10,000 plus an attendance fee of $1,000 for each meeting of such committee that he attends. IGEN maintains a policy for reimbursing all expenses incurred by members of the IGEN board of directors in connection with attendance at board meetings. IGEN's employee directors were not entitled to compensation in their capacities as directors. Under IGEN's 1994 Non-Employee Directors' Stock Option Plan or the 1994 Directors Plan, each non-employee director of IGEN was automatically granted an option to purchase 10,000 shares of IGEN common stock effective on the date of such director's election or appointment to the IGEN board of directors. In addition, non-employee directors were granted additional options from time to time. Set forth below is a table of options granted under this plan to and held by IGEN non-employee directors as of December 1, 2003.

After the completion of the merger, BioVeris's executive compensation committee will determine the compensation of BioVeris's directors. BioVeris anticipates that the compensation for each director will initially be as set forth below. However, BioVeris cannot assure you that changes will not be made to the compensation practices and policies if BioVeris's executive compensation committee deems them appropriate. 164 Following completion of the merger, each non-employee director of BioVeris: - will be entitled to receive an annual retainer of $10,000 and an attendance fee of $1,000 for each meeting of the BioVeris board of directors that he attends; - that serves on the JVOC or the audit committee will be entitled to receive an additional annual retainer of $10,000 plus an attendance fee of $1,000 for each meeting of such committee he attends; and - that serves on the executive compensation committee will be entitled to receive an additional annual retainer of $5,000 plus an attendance fee of $1,000 for each meeting of the executive compensation committee he attends. Under the proposed BioVeris 2003 stock incentive plan, on the day following each annual meeting of stockholders of BioVeris, each non-employee director shall receive an automatic grant of options to purchase 4,000 shares of BioVeris common stock. In addition, any person who is appointed or elected as a non-employee director at any other time shall automatically be granted an option to purchase 4,000 shares of BioVeris common stock on the date of such appointment or election. Each grant will have an exercise price equal to fair market value on the date of grant and will vest in full on the first anniversary of the grant date. Notwithstanding anything herein to the contrary, each non-employee director who is serving at the time the merger is completed will receive an option to purchase 4,000 shares of BioVeris common stock as of the date the merger is completed. EXECUTIVE COMPENSATION Set forth below is information regarding the compensation of BioVeris's executive officers, which are collectively referred to as the named executive officers in this proxy statement/prospectus, while serving as executive officers of IGEN. After the merger, the compensation of BioVeris's named executive officers will be determined by BioVeris's compensation committee. BioVeris anticipates that the annual salary for each of BioVeris's named executive officers will initially be comparable to the salaries they received in fiscal 2003 from IGEN. However, BioVeris cannot assure you that changes will not be made to the compensation practices and policies if BioVeris's compensation committee deems them appropriate. SUMMARY COMPENSATION TABLE The following table sets forth compensation awarded or paid to, or earned by, each of the named executive officers for fiscal 2003, 2002 and 2001. The current annual salary being paid by IGEN to Mr. Samuel Wohlstadter, Dr. Massey and Mr. Migausky is $426,000, $344,000 and $241,000, respectively.

If Mr. George Migausky leaves the employ of IGEN, IGEN may repurchase any shares purchased using this early exercise feature at the exercise price per share to the extent the applicable options were not yet fully vested at that time under the option vesting schedule. (10) Upon completion of the merger, all outstanding options granted under IGEN's stock option plans, including unvested options, will be canceled and the holder of any such options will have the right to receive for each share covered by such option cash from Roche equal to the excess of $47.25 over the exercise price of such option (without interest) and one share of BioVeris common stock. BIOVERIS TERMINATION PROTECTION PROGRAM BioVeris intends to adopt a termination protection program effective upon completion of the merger and related transactions, the purpose of which will be to encourage the named executive officers and other key employees who will participate in the program to continue as employees in the event of a "change of control" of BioVeris, as defined in the termination protection program. The termination protection program will provide that in the event a covered employee's employment is terminated without "cause" or the employee resigns for "good reason" within 30 months following a "change of control" of BioVeris, or a covered employee's employment is terminated prior to a "change of control" at the request of a party involved in such "change of control" or otherwise in connection with or in anticipation of a "change of control," then the employee shall be entitled to receive a cash payment equal to 1.5 to 3 times the sum of the employee's annual salary plus bonus (3 times in the case of the named executive officers). Subject to certain exceptions, "good reason" means, for purposes of the termination protection program, - a decrease in (or failure to increase in accordance with the terms of any employment contract) the covered employee's base salary or bonus opportunity, - a diminution in the aggregate employee benefits and perquisites provided to the covered employee, - a diminution in the covered employee's title, reporting relationship, duties or responsibilities, - relocation of the covered employee's primary office more than 35 miles from its current location, or - the failure by any successor to BioVeris to explicitly assume the termination protection program and BioVeris's obligations thereunder. The termination protection program will also provide that covered employees are entitled to continued welfare and pension benefits for up to 18 months (or in the case of the named executive officers, for up to 36 months (or life, with respect to medical and dental benefits and an annual comprehensive physical)). In addition, the termination protection program will provide reimbursement for outplacement services and will provide a gross-up for any "parachute" excise tax imposed on payments made under the termination protection program, and for the advancement of costs and expenses incurred by the employee related to the termination protection program. TRANSACTION BONUS PAYMENTS Simultaneous with completion of the merger and related transactions, the following executive officers of IGEN will be entitled to receive transaction bonus payments in the amounts set forth below: TRANSACTION NAME BONUS ---- ----------- Samuel J. Wohlstadter....................................... $1,278,000 Richard J. Massey, Ph.D..................................... 450,000 George V. Migausky.......................................... 450,000 Each transaction bonus payment is contingent upon the individual executive officer providing a release of the respective obligations of IGEN and BioVeris under IGEN's termination protection program. 168 CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS MSD AND THE MSD AGREEMENTS MSD is a joint venture formed by MST and IGEN in 1995. MSD was formed for the development, manufacture, marketing and sale of products utilizing a combination of MST's multi-array technology together with IGEN's technology. MST is a company established and wholly-owned by Mr. Jacob Wohlstadter, a son of IGEN's and BioVeris's chief executive officer. In August 2001, IGEN amended the MSD joint venture agreement, the MSD limited liability company agreement and certain license and other agreements with MSD and MST to continue the MSD joint venture and entered into various related agreements, including employment and consulting agreements with Mr. Jacob Wohlstadter. These agreements, as amended, are referred to in this proxy statement/prospectus as the MSD agreements. An independent committee of the IGEN board of directors, with the advice of independent advisors and counsel, negotiated and approved the MSD agreements. As part of the restructuring, IGEN will transfer its equity interest in MSD to BioVeris and will assign the MSD agreements to BioVeris. While the MSD joint venture agreement will expire upon the completion of the merger, BioVeris will continue to hold its limited liability company interest in MSD unless and until MSD or MST exercises its right to purchase BioVeris's interest on the terms provided in the MSD joint venture agreement and described below or unless BioVeris transfers its interest, which transfer requires the consent of MST. MSD manufactures, markets and sells instrument systems, including the Sector HTS and the Sector PR, which combine MST's multi-array technology and IGEN's ECL technology. The Sector HTS is an ultra high throughput drug discovery system engineered for applications such as high throughput screening and large-scale proteomics. The Sector PR is a smaller system designed for benchtop applications such as assay development, research in therapeutic areas, cellular biology and medium throughput screening. MSD also manufactures and markets a line of its own reagents, assays and plates that are used on these systems. MSD commenced product sales in October 2002, and, during fiscal 2003, MSD had product sales of $3.2 million and a net loss of $18.2 million. Under the MSD agreements, IGEN's funding commitment to MSD was based on an annual budget of MSD approved by the JVOC, a committee of the IGEN board of directors consisting of independent directors. The JVOC approved funding for MSD by IGEN for the period from January l, 2003 to November 30, 2003 in an amount of $20.6 million, subject to a permitted variance of 15%. As of September 30, 2003, IGEN's remaining funding commitment to MSD was $5.4 million and, except as described in the next paragraph, IGEN has no commitment to provide any funding to MSD for any period after November 30, 2003. IGEN's remaining funding commitment may be satisfied in part through in-kind contributions of scientific and administrative personnel and shared facilities. For fiscal 2003, 2002 and 2001, IGEN made total contributions to MSD of $20.5 million, $19.6 million and $8.3 million, respectively. During fiscal 2002, IGEN transferred certain equipment and leasehold interests to MSD in the amount of $839,000, which amount is included in the in-kind contributions to MSD in such year. Separate from and in addition to IGEN's remaining funding commitment under the MSD agreements for the period from January 1, 2003 to November 30, 2003, BioVeris has agreed under the MSD letter agreement to make a final capital contribution of $37.5 million to MSD on the first business day following the completion of the merger. Of the $37.5 million, Mr. Samuel Wohlstadter will fund any amount in excess of $30.0 million (including any interim funding provided by IGEN as described in the next sentence) through the purchase of shares of BioVeris series B preferred stock that economically mirror the class C interests in MSD to be held by BioVeris, as specified in the BioVeris preferred stock purchase agreement. In addition, in the event the merger is not completed prior to December 1, 2003, IGEN has agreed under the MSD letter agreement to provide continued interim funding to MSD payable monthly on the first day of each month commencing on December 1, 2003 until the earlier to occur of completion of the merger or termination of the merger agreement. The monthly interim funding will equal approximately $1.7 million, which is one-twelfth of IGEN's aggregate funding commitment under the MSD budget for 2003 approved by the JVOC. Any interim funding will reduce the amount of BioVeris's final capital contribution following the completion of the merger. 169 In addition, the indemnified parties and IGEN entered into a letter agreement dated August 15, 2001, which will be assumed by BioVeris as part of the restructuring. Pursuant to the letter agreement, IGEN agreed to fund the reasonable ongoing legal fees and related charges and costs incurred by the indemnified parties arising out of or related to the Roche litigation, including any legal fees and related charges and costs arising out of or related to any of IGEN's ongoing negotiations regarding, and the settlement of, the Roche litigation. MSD has submitted to IGEN invoices for legal fees and expenses for the period from March 1, 2003 through September 30, 2003 in the amount of approximately $1.3 million that it asserts were reasonably incurred in connection with the indemnified parties' participation and involvement in IGEN's ongoing negotiations and settlement of the Roche litigation and their review of the documents relating to the merger and related transactions. The indemnified parties have claimed that IGEN must reimburse these fees and expenses pursuant to the letter agreement. The JVOC, through its counsel, has reviewed the relevant invoices, and has approved the payment to MSD of, and IGEN has paid, approximately $423,000 of the submitted expenses, which the JVOC believes is the maximum amount IGEN is obligated to pay under the terms of the letter agreement for the period from March 1, 2003 through September 30, 2003. The indemnified parties, through their counsel, have not accepted the JVOC's determination, and the JVOC believes it is likely that the indemnified parties will continue to seek reimbursement for the balance of the $1.3 million claimed, which approximates $877,000. In addition, MSD submitted to IGEN invoices for legal fees and expenses of approximately $26,000 for October 2003 and approximately $21,000 for November 2003, which the indemnified parties have also claimed that IGEN must reimburse pursuant to the letter agreement. The JVOC has not yet made any determination regarding MSD's claims for October 2003 and November 2003. The JVOC expects that the indemnified parties will submit claims for reimbursement of additional expenses for the period from December 1, 2003 through the completion of the merger. No amount that may be paid by IGEN or BioVeris under these invoices or pursuant to such agreement shall unless otherwise agreed by the parties be deemed or construed as a capital contribution to MSD or otherwise offset IGEN's remaining funding commitment to MSD. The obligations of IGEN or BioVeris, as the case may be, under the letter agreement are separate from and in addition to their obligations under the MSD agreements. After the restructuring, and subject to MSD's and MST's right to buy BioVeris's interest in MSD, BioVeris will replace IGEN as a member of MSD and will hold a 31% voting equity interest in MSD and be entitled to a preferred return on $72.2 million of the funds previously invested by IGEN in MSD through September 30, 2003 and on all additional funds invested by IGEN and BioVeris thereafter, including the $37.5 million contribution to be made following the completion of the merger. This preferred return would be payable out of a portion of both future profits and certain third-party financings of MSD, generally before any payments are made to other equity holders. MST is the only other member of MSD and owns the remaining 69% voting equity interest in MSD. Although the MSD joint venture agreement will expire upon completion of the merger, unless and until MSD or MST exercises its right described below to purchase BioVeris's interest in MSD, BioVeris will retain the right to appoint 1 of 2 members of MSD's board of managers, and BioVeris will generally have the right to approve significant MSD governance matters. In exercising this right, an independent committee of the BioVeris board of directors must consider BioVeris's interests and the interests of BioVeris stockholders while also taking into consideration the interests of MSD. After the restructuring, Dr. Richard Massey, IGEN's and BioVeris's president and chief operating officer, will be BioVeris's representative on the MSD board of managers and will also serve as the treasurer and secretary of MSD. Dr. Massey will receive no compensation from MSD or BioVeris for serving as the treasurer and secretary of MSD. The other member of the MSD board of managers is Mr. Jacob Wohlstadter, who is the sole owner of MST and serves as president and chief executive officer of MSD. Neither Dr. Massey nor any other executive officer or director of IGEN or BioVeris has any ownership interest in MST or MSD, other than through ownership of interests in IGEN or BioVeris and other than the BioVeris series B preferred stock to be purchased by Mr. Samuel Wohlstadter to the extent that BioVeris's final capital contribution (including any interim funding provided by IGEN as described in the second preceding paragraph) exceeds $30.0 million. Mr. Samuel Wohlstadter and Mrs. Nadine 170 Wohlstadter disclaim any ownership interest in MST or MSD as a result of Mr. Jacob Wohlstadter's ownership interest in those entities. Under the terms of the IGEN/MSD license agreement, which is one of the MSD agreements, BioVeris granted to MSD a worldwide, perpetual, exclusive license (with certain exceptions) to BioVeris's technology, including ECL technology, for use in MSD's research program, defined in the MSD agreements and which is referred to in this proxy statement/prospectus as the MSD research program. The MSD research program involves the use in diagnostic procedures, including diagnostic procedures utilizing ECL technology, of: - selection and screening methods, including high throughput screening and methods involving large numbers of determinations, in each case relating only to claimed or inventive subject matter of the patents or know-how licensed by MST to MSD; - disposable electrodes; and - multi-array diagnostic. MSD and MST signed a consent to the licenses granted to the license sub in the license agreement under which they consented to and joined in such licenses and waived any right to restrict or limit the license sub's and its affiliates' exercise of the licenses granted in the license agreement. In the restructuring, IGEN will assign the IGEN/MSD license agreement to BioVeris. The IGEN/MSD license agreement will survive expiration of the MSD joint venture agreement and the termination of BioVeris's status as a member of MSD. In addition, if BioVeris ceases to be a member of MSD, it will become entitled to receive quarterly royalty payments from MSD of 3% of the net sales price on all products developed and sold by MSD using the patents BioVeris will receive as part of the restructuring. The royalty obligation will expire as the relevant BioVeris patents expire. MST holds a worldwide, perpetual, non-exclusive sublicense from MSD, which is referred to in this proxy statement/prospectus as the MSD/MST sublicense agreement, to use BioVeris's technology to make, use or sell products or processes applying or related to the technologies used in the MSD research program outside the diagnostic field. For purposes of the MSD agreements, the diagnostic field is defined to mean all diagnostic devices and procedures for the measurement or detection of identifiable substances for human clinical research, environmental, agricultural, veterinary, food testing, industrial or similar purposes. BioVeris is entitled to receive quarterly royalty payments from MST of 6% of the net sales price on any products developed and sold by MST using the patents BioVeris will receive as part of the restructuring. BioVeris will assume IGEN's obligation under the MSD agreements to make its technology available for sublicense by MSD to MST, and these obligations will survive the expiration of the MSD joint venture agreement and the termination of BioVeris's or MST's status as a member of MSD. BioVeris will not, however, be obligated to make available for sublicense by MSD to MST any technology or improvements to BioVeris's technology developed after the expiration of the MSD joint venture agreement or the termination of BioVeris's or MST's status as a member of MSD. In addition, BioVeris may terminate its participation in the MSD/MST sublicense agreement upon MSD's or MST's material breach, after notice and an opportunity to cure the breach. During the term of the MSD joint venture agreement, MSD is IGEN's and MST's exclusive means of conducting the MSD research program, and IGEN is obligated to refrain from developing or commercializing any products, processes or services that are related to the MSD research program in the diagnostic field, as defined for the purposes of the MSD agreements, or to MSD's research technologies as described in the MSD agreements, subject to certain exceptions. As part of the MSD joint venture agreement, MSD granted to BioVeris an exclusive, worldwide, royalty-free license to use in the diagnostic field certain defined improvements developed by MSD in the MSD research program. After the expiration or termination of the MSD joint venture agreement, the license granted to BioVeris to use in the diagnostic field certain defined ECL improvements developed by MSD will remain in effect. However, BioVeris, may not make, use or sell products, processes or services that use certain defined ECL improvements granted to it by MSD if doing so would compete with MSD in the diagnostic field or use 171 research technologies defined in the MSD agreements. In addition, after BioVeris ceases to be member of MSD, MSD may require BioVeris to distribute its products pursuant to a mutually agreeable distribution agreement, and BioVeris will be required to pay to MST a royalty of 3% of net sales of MSD products sold by BioVeris. During its term, the MSD joint venture agreement limits the business of MSD to performing the MSD research program and developing, manufacturing, marketing and selling products in the diagnostic field. After termination of the MSD joint venture agreement, this limitation on MSD's business activity will no longer apply. Furthermore, following the termination or expiration of the MSD joint venture agreement, BioVeris will remain subject to limitations on its ability to manufacture, market and sell in the diagnostic field, as defined in the MSD agreements, instruments that use an electrode to start the ECL process where the electrode is disposable, consumable or not permanently installed and MST will retain sole ownership of all inventions, concepts, know-how and technology developed by MSD as well as all patent applications, patents and copyrights. As part of the merger agreement and related transaction agreements, BioVeris, IGEN and MSD agreed that the MSD joint venture agreement will expire on the later of November 30, 2003, or the earlier of the date of the completion of the merger and related transactions or the termination of the merger agreement. In addition, in accordance with the MSD agreements, MST and MSD have the right to terminate the MSD joint venture agreement prior to its expiration under certain circumstances, including - breach of IGEN's obligations, including IGEN's funding obligations to MSD, - MSD's termination of Mr. Jacob Wohlstadter's employment (other than for cause or disability), - if Mr. Jacob Wohlstadter is entitled to terminate his employment agreement for good reason (as defined in his employment agreement) or - upon a change in control of IGEN, as defined. MSD and Mr. Jacob Wohlstadter have each agreed that the merger and related transactions will not constitute a change in control for purposes of the MSD agreements. As part of the restructuring, IGEN's equity interest in MSD will be transferred to BioVeris because Roche did not want to acquire the interest. MSD and MST do not have the right to purchase IGEN's or BioVeris's, as the case may be, interest in MSD until the MSD joint venture agreement expires, or in certain cases, is terminated. The MSD joint venture agreement will expire upon completion of the merger and, as a result, MSD and MST will have the right to purchase for a purchase price equal to fair market value (to be determined as described below), less a 7.5% discount factor, BioVeris's entire interest in MSD, including BioVeris's preferred interests that entitle it to a preferred return on its investment in MSD. MSD or MST has until 90 days following the completion of the merger to exercise its right to begin the sale process. Under the MSD joint venture agreement, the parties must negotiate in good faith for 30 days to attempt to agree on a purchase price for BioVeris's interest, after which time the MSD joint venture agreement provides for an appraisal of the fair market value of BioVeris's interest in MSD (including its preferred interests). The MSD joint venture agreement provides for this appraisal to be accomplished within 45 days after appraisers are appointed by each of BioVeris and either MSD or MST, as applicable, but may be extended an additional 45 days or more through the required appointment of a third appraiser if the value determined by the first two appraisers differs by more than 10%. Fair market value will equal the average of the determinations of both appraisers, if there are only two appraisers, or the average of the two closest determinations, if there are three appraisers. The JVOC will, on behalf of BioVeris, conduct the negotiations to determine the purchase price of BioVeris's interest in MSD. Neither Mr. Samuel Wohlstadter, Dr. Richard Massey nor any other interested party will participate on behalf of BioVeris in the negotiations. In addition, Dr. Richard Massey, who is IGEN's representative and who will be BioVeris's representative on the MSD board of managers and is and will be MSD's treasurer and secretary immediately following the restructuring, will not participate on behalf of MSD in the negotiations. MSD or MST must exercise its right to purchase BioVeris's interest within 60 days after the purchase price has been determined pursuant to this appraisal process. If MSD or MST exercises this right, it will be required to pay BioVeris the outstanding purchase price plus simple (cumulated, not 172 compounded) interest at the fixed annual rate of 0.5% over the prime rate in effect on the date that MSD or MST, as the case may be, elects to purchase the interests. The purchase price is payable over time in installments equal to the sum of 5% of MSD net sales, as determined in accordance with the MSD agreements, and 20% of the net proceeds realized by MSD from the sale of its debt or equity securities in any third-party financing after the date of the sale of BioVeris's interest in MSD. In the event such net sales or third-party financings do not materialize, BioVeris will not receive any payments from MSD or MST, as the case may be, for the purchase of BioVeris's interest in MSD. As security for the payment obligation, BioVeris will hold a security interest in the interests in MSD that are being purchased. MST or MSD, as the case may be, may repay all or any part of the outstanding purchase price plus accrued interest at any time and from time to time without penalty. Each of BioVeris and either MSD or MST, as applicable, will be responsible for all fees and costs of the appraiser designated by it and one-half of all fees and costs of the third appraiser, if any, provided that, upon the election of MSD or MST, as applicable, IGEN will pay MSD's or MST's, as applicable, share of such fees and costs, in which case such fees and costs may be added to the purchase price of BioVeris's interest in MSD. Following the expiration of the MSD joint venture agreement, if MSD or MST exercises its right to purchase BioVeris's interest in MSD, BioVeris will: - remove its appointed designee from MSD's board of managers; - vote its interest in MSD in the manner requested by MST, subject to certain limitations; - provide reasonable cooperation and provide such consents (including the execution and delivery of amendments to the MSD agreements as may be reasonably required) to permit MSD to raise additional capital; and - terminate its status as a party to the MSD/MST license agreement. Following the expiration of the MSD joint venture agreement, many of the licenses and other arrangements with MSD and MST assigned to BioVeris will continue indefinitely in accordance with their terms. These include the IGEN/MSD license agreement, the MSD/MST sublicense agreement (but only as to IGEN or BioVeris technology or improvements developed before IGEN or BioVeris ceases to be a member of MSD), and certain indemnification obligations to Mr. Jacob Wohlstadter. In addition, certain of BioVeris's obligations under the MSD joint venture agreement will survive its termination, including: - to cooperate and work in good faith and use reasonable best efforts to assist MSD in securing third-party financing, - confidentiality obligations, - to make available to MSD the benefits of certain agreements with third-party licensors, suppliers, vendors, distributors and other providers, - to assign to MSD all proprietary information and intellectual property within the MSD research program or research technologies, as described in the MSD agreements, and to ensure that its employees protect such proprietary information, - to defend and indemnify MSD against all claims arising out of the conduct of the MSD research program and to maintain liability insurance to cover the risk of liability resulting from the conduct of that program, and - unless MSD or MST exercises its right to purchase BioVeris's interests in MSD, not to vote against or refuse to consent to, agree to or approve any action supported by MST unless a committee of the BioVeris board of directors reasonably concludes, after having considered the interests of MSD, that the action is not in the best interests of BioVeris and its stockholders. Notwithstanding termination of the MSD joint venture agreement, BioVeris will be required to continue to pay the expenses associated with prosecuting and maintaining the patents licensed by MST to 173 MSD in connection with the original formation of the MSD joint venture unless and until MSD or MST exercises its right to purchase BioVeris's interests in MSD. Following the expiration of the MSD joint venture agreement, BioVeris will no longer be required to provide research personnel and corporate services to MSD. Nevertheless BioVeris expects that it will continue to provide these services to MSD on a transitional basis at MSD's expense. In addition, following the expiration or termination of the MSD joint venture agreement, MSD will be entitled to continue to lease certain facilities and related equipment from BioVeris (including laboratory facilities located in BioVeris's corporate headquarters) pursuant to the terms of the existing sublease agreements with MSD. The term of each sublease will expire one day prior to the expiration of the prime lease for that facility. Each sublease agreement provides that, subject to certain exceptions, BioVeris must exercise all available extension rights under the prime lease. Following termination or expiration of the MSD joint venture agreement, each of MSD and BioVeris may unilaterally terminate any or all of the subleases by providing at least 18 months prior written notice of termination. If BioVeris elects to terminate a sublease for a facility, MSD may elect, notwithstanding any termination of the sublease, to remain in the subleased facility after the 18-month period expires for any period of time selected by MSD, but not longer than one day prior to the expiration of the prime lease (including any extensions of the prime lease). After a notice of termination of a sublease has been sent, MSD will be required to pay its pro rata share of all rental and other expenses incurred by BioVeris under the prime lease. MSD and MST may elect, if either exercises its right to purchase BioVeris's interests in MSD, to have its rental and expense payment obligations for the 18-month period included in the purchase price of those interests in MSD. In addition, following the termination or expiration of the MSD joint venture agreement, the restrictions on MSD offering employment to employees of BioVeris will cease. MSD has an employment agreement with Mr. Jacob Wohlstadter, its president and chief executive officer, the current term of which runs through November 30, 2004. The term of the employment agreement will automatically renew for a 12-month period on November 30 of each year unless either MSD or Mr. Jacob Wohlstadter gives notice of termination no later than 180 days prior to that renewal date. That employment agreement provides for a salary at the annual rate of $250,000 through November 30, 2003. Thereafter, the salary is to be increased as agreed to by MSD and Mr. Jacob Wohlstadter. In addition, Mr. Jacob Wohlstadter is also eligible to receive, at the discretion of the JVOC of the IGEN or BioVeris board of directors, as the case may be, an annual cash bonus in an amount not to exceed 20% of his annual salary. Mr. Jacob Wohlstadter is also entitled to receive pension, welfare and fringe benefits comparable to those received by senior executives of BioVeris and other insurance benefits. If MSD terminates the employment agreement without cause, or Mr. Jacob Wohlstadter terminates the employment agreement for good reason (which includes a "change in control" of BioVeris, as defined), Mr. Jacob Wohlstadter will be entitled to receive, in addition to salary and pro rata bonus and adjustments earned through the 60th day following the notice of termination, an amount equal to from 3 to 12 times (depending on the reason for the termination) the monthly pro rata salary, bonus and adjustments in effect at the time of the termination. Under the employment agreement, Mr. Jacob Wohlstadter is also entitled to receive a gross-up for any "parachute" excise tax that may be imposed on payments made or benefits provided pursuant to the agreement. In addition, upon such a termination prior to the expiration of the MSD joint venture agreement, MSD and MST will have a joint right to purchase BioVeris's interest in MSD on the terms described above. BioVeris will be responsible directly or indirectly for all amounts payable, costs incurred and other obligations under the employment agreement prior to the termination of BioVeris's funding obligation to MSD upon completion of the merger, which generally are expected to be paid out of its funding commitment to MSD. That funding commitment ends when the merger is completed as will most of BioVeris's obligations under the employment agreement, except that BioVeris will remain obligated to maintain in effect directors and officers liability insurance coverage for Mr. Jacob Wohlstadter and to pay Mr. Jacob Wohlstadter the applicable salary, pro rata bonus and adjustments in effect at the time of termination as described above and a gross-up for any "parachute" excise tax that may be imposed. MSD and Mr. Jacob Wohlstadter have each agreed that the merger and related transactions will not constitute a change in control for purposes of the MSD agreements and the 174 employment agreement. BioVeris will also indemnify Mr. Jacob Wohlstadter against certain liabilities, including liability from the MSD joint venture relating to the period of IGEN's or BioVeris's involvement with MSD. During the years ended March 31, 2003, 2002 and 2001, BioVeris's contributions to MSD were $20.5 million, $19.6 million and $8.3 million, respectively. During the years ended March 31, 2003, 2002 and 2001, BioVeris recorded $17.6 million (as equity in loss of joint venture), $13.3 million ($10.9 million as equity in loss of joint venture and $2.4 as research and development expense), and $8.3 million (as research and development expense), respectively. BioVeris's investment in affiliate totaled $9.2 million and $6.2 million at March 31, 2003 and 2002, respectively. Effective October 1, 2003 IGEN will consolidate the financial results of MSD in accordance with the Financial Accounting Standards Board Interpretation No. 46, "Consolidation of Variable Interest Entities." See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Critical Accounting Policies -- Joint Venture Accounting" and "Consolidated Financial Statements -- Notes to Consolidated Financial Statements -- Note 4 -- Meso Scale Diagnostics Joint Venture" for discussion of consolidation accounting of the MSD investment. Mr. Jacob Wohlstadter has a consulting agreement with IGEN that will be assumed by BioVeris. This consulting agreement will be automatically renewed on August 15, 2004, for a period of three years unless either BioVeris or Mr. Jacob Wohlstadter gives notice to the contrary no later than 90 days before that date. Pursuant to the consulting agreement, Mr. Jacob Wohlstadter will be entitled to receive such fees as BioVeris and Mr. Jacob Wohlstadter agree to when consulting services are requested by BioVeris. BioVeris has no obligation to request any consulting services from Mr. Jacob Wohlstadter. During fiscal 2002, Mr. Jacob Wohlstadter received $275,000 from IGEN for consulting services performed for IGEN for the period 1995 through 2001. Mr. Jacob Wohlstadter did not perform any compensable consulting services during fiscal 2002, 2003 or the six months ended September 30, 2003. In his role as a consultant, Mr. Jacob Wohlstadter also received stock option grants from IGEN. In May 1997, he was granted options to purchase 180,000 shares of IGEN common stock with an exercise price of $6.00 per share, which was the fair market value on the date of grant. These options will expire on May 8, 2007, and are fully vested. In August 2000, Mr. Jacob Wohlstadter was granted options to purchase 75,000 shares of IGEN common stock, with an exercise price of $18.75 per share, which was the fair market value on the date of grant. These options will expire on August 1, 2010, and 48,749 shares are exercisable as of December 1, 2003. Upon completion of the merger, these options will be canceled and Mr. Jacob Wohlstadter will have the right to receive for each share covered by such option cash from Roche equal to the excess of $47.25 over the exercise price of such option (without interest) and one share of BioVeris common stock. Mr. Jacob Wohlstadter and JW Consulting Services, L.L.C., a company established and wholly-owned by Mr. Jacob Wohlstadter, have an indemnification agreement with IGEN that BioVeris will assume. Pursuant to the indemnification agreement, BioVeris will indemnify Mr. Jacob Wohlstadter and JW Consulting Services, L.L.C. against any claims arising out of the performance or non-performance of services to or for the benefit of BioVeris. In addition, BioVeris will be obligated under the MSD limited liability company agreement to indemnify each officer and member of the board of managers of MSD with respect to any action taken by such person during the time IGEN or BioVeris, as the case may be, was a member of MSD by reason of the fact that such person is or was an officer or a member of the board of managers of MSD. RELATED COMPANIES In fiscal 1994, IGEN entered into a joint venture with Hyperion to develop and commercialize biomedical products utilizing advanced materials. In fiscal 1995, the joint venture was terminated and IGEN entered into a supply agreement with Hyperion. Dr. Richard Massey and Mr. Samuel Wohlstadter are directors of Hyperion. In addition, Mr. Samuel Wohlstadter is the principal and controlling stockholder of Hyperion, beneficially owning more than 50% of the outstanding common stock of Hyperion. Mr. Samuel Wohlstadter is also the chief executive officer of Hyperion. During fiscal 2003, IGEN did not 175 pay to, or receive from, Hyperion any amounts under these agreements. In addition, Hyperion has a shared services arrangement with BioVeris under which BioVeris will provide certain administrative and other services at cost to Hyperion. The total amounts billed to by Hyperion under this arrangement for fiscal 2003 and the six months ended September 30, 2003 were $338,000 and $147,000, respectively. Amounts due under this arrangement were $175,000 and $67,000 at March 31, 2003 and September 30, 2003, respectively, which were paid subsequent to each respective period end. Mr. Samuel Wohlstadter is also the principal and controlling stockholder, a director and the chief executive officer of each of Wellstat Biologics, Wellstat Therapeutics and Proteinix. Dr. Massey is a less than 10% stockholder in Proteinix. In 1993, IGEN licensed certain diagnostic technologies from, and certain pharmaceutical technologies to, Proteinix and Wellstat Therapeutics. No royalties have ever been earned or accrued under these agreements. Wellstat Biologics, Proteinix and Wellstat Therapeutics each has had a shared services arrangement with IGEN since 1994, 1992 and 1986, respectively, under which IGEN provides and BioVeris will provide certain services. These services include accounting and finance, human resources and other administrative services, as well as facility related costs and services. The total amounts billed to Wellstat Biologics, Wellstat Therapeutics and Proteinix under this agreement for fiscal 2003 were $313,000, $352,000 and $6,000, respectively, and for the six months ended September 30, 2003 were $150,000, $210,000 and $62,000, respectively. Amounts due under these arrangements were $53,000 and $227,000 at March 31, 2003 and September 30, 2003, respectively, which were paid subsequent to each respective period end. In 1993, IGEN enacted a reorganization that included the discontinuation of its pharmaceutical development operations. As part of that reorganization, IGEN entered into an agreement with Pro-Neuron, Inc., which was renamed Wellstat Therapeutics. Under the agreement, Wellstat Therapeutics assumed contractual and financial responsibility for IGEN's commitments, agreements and contract research programs related to the IGEN prodrug cancer program. In connection with this assumption, IGEN granted to Wellstat Therapeutics an exclusive, worldwide and perpetual license to its patents, patent applications, know-how and trade secrets relating to the IGEN prodrug cancer program, subject to certain limitations. IGEN was entitled to receive a royalty from Wellstat Therapeutics based on net sales of products made pursuant to the license. To date, there have been no products developed under this license. At the same time, Wellstat Therapeutics granted to IGEN an exclusive, worldwide and perpetual license to its patents, patent applications, know-how and trade secrets relating to Wellstat Therapeutics's proprietary diagnostics product opportunities, subject to certain limitations, in a field that includes research, industrial and clinical diagnostic markets. Wellstat Therapeutics was entitled to receive a royalty from BioVeris based on net sales made pursuant to the license. To date, there have been no products developed under this license. In connection with the assumption of contractual and financial responsibility for IGEN's commitments, agreements and contract research programs and the grants of the licenses, Wellstat Therapeutics was paid $5 million by IGEN, which was scheduled to convert into 4.5% of the fully diluted equity of Wellstat Therapeutics on December 31, 2003. This equity right has no historic cost basis in the consolidated financial statements of IGEN. In lieu of the conversion, IGEN and Wellstat Therapeutics have agreed on the terms of an equity right purchase and license amendment agreement pursuant to which - Wellstat Therapeutics would repurchase IGEN's right to receive a 4.5% equity interest in Wellstat Therapeutics, - the existing intellectual property licenses from IGEN to Wellstat Therapeutics and from Wellstat Therapeutics to IGEN would be terminated, and - IGEN would confirm the 1993 transfer to Wellstat Therapeutics of its interest in the ProGen joint venture through which IGEN had conducted its prodrug research prior to the execution of the 1993 agreement. In return, Wellstat Therapeutics would pay IGEN $1.7 million in cash. The parties have agreed that the transactions will be completed up to two business days prior to the transfer of assets from IGEN to BioVeris pursuant to the restructuring agreement. IGEN's audit committee, with the assistance of independent financial and legal advisors, negotiated and approved the agreement on behalf of IGEN. The 176 agreement between IGEN and Wellstat Therapeutics is subject to obtaining the consent of Roche pursuant to the terms of the merger agreement and to the negotiation and execution of sublicenses for certain of the acquired intellectual property. Also in 1993, as part of the discontinuation of its pharmaceutical development operations, IGEN entered into an agreement with Proteinix. Under the agreement, Proteinix assumed contractual and financial responsibility for IGEN's commitments, agreements and contract research programs related to the IGEN Abzymes program development operations. In connection with this assumption, IGEN granted to Proteinix an exclusive, worldwide and perpetual license to its patents, patent applications, know-how and trade secrets relating to the IGEN Abzymes program, subject to certain limitations. IGEN was entitled to receive a royalty from Proteinix based on net sales of products made pursuant to the license. To date, there have been no products developed under this license. At the same time, Proteinix granted to IGEN an exclusive, worldwide and perpetual license to its patents, patent applications, know-how and trade secrets relating to Proteinix's ubiquitin fusion technology for the production of diagnostic reagents together with product opportunities, subject to certain limitations, in a field that includes research, industrial and clinical diagnostic markets. Proteinix was entitled to receive a royalty from BioVeris based on net sales made pursuant to the license. To date, there have been no products developed under this license. In connection with the assumption of contractual and financial responsibility for IGEN's commitments, agreements and contract research programs and the grants of the licenses, Proteinix was paid $3.2 million by IGEN, which was scheduled to convert into 4.5% of the fully diluted equity of Proteinix on December 31, 2003. This equity right has no historic cost basis in the consolidated financial statements of IGEN. In lieu of the conversion, IGEN and Proteinix have agreed on the terms of an equity right purchase and license amendment agreement pursuant to which - Proteinix would repurchase IGEN's right to receive a 4.5% equity right in Proteinix, - the intellectual property licenses from IGEN to Proteinix and from Proteinix to IGEN would be terminated, and - Proteinix would purchase the intellectual property assets, including the "Abzyme" trademark, underlying the licenses between IGEN and Proteinix and between IGEN and Wellstat Therapeutics. In return, Proteinix would pay IGEN $50,000 in cash and grant to IGEN a fully-paid, worldwide, perpetual, royalty-free, non-exclusive license to practice all diagnostic rights in the abzyme technology embodied in the sold intellectual property. IGEN would have limited rights to sublicense this intellectual property to strategic partners, customers, distributors and in the context of bona fide research collaborations. The parties have agreed that the IGEN-Proteinix transaction will be completed at the same time as the closing of the IGEN-Wellstat Therapeutics transaction, up to two business days prior to the transfer of assets from IGEN to BioVeris pursuant to the restructuring agreement. IGEN's audit committee, with the assistance of independent financial and legal advisors, negotiated and approved the agreement on behalf of IGEN. The agreement between IGEN and Proteinix is also subject to obtaining the consent of Roche pursuant to the terms of the merger agreement and the negotiation and execution of sublicenses to certain of the acquired intellectual property. In approving the agreements with Wellstat Therapeutics and Proteinix, the audit committee and its advisors considered a number of factors, including the following facts: - neither Wellstat Therapeutics nor Proteinix has developed any products utilizing the intellectual property that would result in a commercially viable product during the remaining useful life of the applicable patents licensed to those companies in 1993, and neither company has expressed any intention to utilize such property; - BioVeris has no current plans to utilize the technology it proposes to sell to Proteinix, but nonetheless will retain rights to utilize it in the diagnostic field should it find it advantageous to do so; - the patents underlying the licenses (and that are proposed to be sold to Proteinix) generally have remaining lives of five to eight years, which the audit committee believed was unlikely to give 177 Wellstat Therapeutics or Proteinix (or any person to whom either of them may transfer their exclusive license rights) sufficient time to discover and formulate a commercially viable product that would produce royalties under the existing licenses from IGEN; - the expiration of the equity conversion rights had been extended several times, and the parties did not wish to extend further the date on which the equity rights would mature past December 31, 2003; - the audit committee's determination that IGEN should take steps to minimize the number and complexity of relationships with related parties in connection with the transfer of assets to BioVeris pursuant to the restructuring agreement; - BioVeris would no longer be required to continue to incur the expenses associated with maintaining the intellectual property assets underlying the licenses between IGEN and Proteinix and between IGEN and Wellstat Therapeutics; - the advice of the audit committee's independent financial advisor concerning the value of the potential equity interests in Wellstat Therapeutics and Proteinix; - Proteinix has been a dormant company for several years; - the parties disputed the basis on which the "fully diluted" equity would be calculated in light of the significant debt owed by Wellstat Therapeutics to Mr. Samuel Wohlstadter; and - neither Wellstat Therapeutics nor Proteinix has outside funding sources available to it, and each is dependent on Mr. Samuel Wohlstadter for continued funding. In approving the agreements with Wellstat Therapeutics and Proteinix, the audit committee did not quantify, or otherwise attempt to assign any relative values to these factors. The audit committee viewed its decision to approve the agreements based on the totality of the information presented to and considered by it, and determined that the cash and other benefits proposed to be received by IGEN represented fair consideration for the equity and intellectual property rights proposed to be sold by IGEN. TRANSACTIONS WITH DIRECTORS AND EXECUTIVE OFFICERS In connection with the exercise of employee stock options in July 2000, Mr. Samuel Wohlstadter, IGEN's and BioVeris's chief executive officer, received a loan from IGEN. The loan was a 6.62% simple interest only, full recourse loan against all assets of Mr. Samuel Wohlstadter in the principal amount of $2,060,500 maturing in July 2007. Interest charged to and paid by Mr. Samuel Wohlstadter under this loan arrangement during fiscal 2003 was $136,405. The loan is collateralized by the pledge of 100,000 shares of IGEN common stock. This loan will be transferred to BioVeris as part of the restructuring and will be repaid upon completion of the merger. In connection with the exercise of an employee stock option in July 2000, Dr. Richard Massey, president and chief operating officer, received a loan from IGEN. The loan was a 6.62% simple interest only, full recourse loan against all assets of Dr. Massey in the principal amount of $1,649,000, maturing in July 2007. Interest charged to and paid by Dr. Massey under this loan arrangement during fiscal 2003 was $109,164. The loan was collateralized by the pledge of 80,000 shares of IGEN common stock owned by Dr. Massey. This loan has been repaid in full and the pledged collateral has been released. Since 1995, IGEN has retained Wilmer, Cutler & Pickering to perform legal services in connection with the Roche litigation and other matters. Mr. Richard Cass, one of IGEN's directors, is a partner of the law firm of Wilmer, Cutler & Pickering and is chairman of its Corporate Practices Group. In addition, Ms. Jennifer M. Drogula, who became the daughter-in-law of IGEN's and BioVeris's chairman and chief executive officer in March 2002, has been a partner of the firm since January 1, 2001. IGEN recorded approximately $2.1 million, $11.2 million and $5.8 million in legal fees to the law firm for fiscal 2003, 2002 and 2001, respectively. Amounts due to the law firm totaled $432,000 and $1.7 million as of March 31, 2003 and 2002, respectively. BioVeris expects that it will continue to retain the law firm in the future. In addition, IGEN engaged the law firm of Hale and Dorr LLP to provide legal services in connection with the Roche litigation and otherwise. IGEN first engaged this law firm in 1994. Ms. Deborah Wohlstadter, the wife of Mr. Jacob Wohlstadter and daughter-in-law of IGEN's and 178 BioVeris's chairman and chief executive officer since December 2001, is a junior partner in that law firm. IGEN recorded approximately $396,000 in legal fees paid to that firm during fiscal 2003. BioVeris expects that it will continue to retain the law firm in the future. In 2001, Brown Simpson and Laurence Paskowitz initiated separate stockholder derivative lawsuits for and on behalf of the shareholders of IGEN in the Circuit Court for Montgomery County, Maryland, or the Circuit Court, against four of IGEN's current directors, two former directors, three executive officers and IGEN as a nominal defendant. The complaints alleged breach of fiduciary duties by the named individual defendants in connection with transactions between IGEN and other entities in which certain directors and officers are alleged to have an interest, including MSD. Both lawsuits sought principally the following: that the defendants hold in trust and be required to account for and restore to IGEN damages that it has allegedly sustained by reason of the allegations and relief relating to board and management composition. The Paskowitz complaint also sought damages for a class of IGEN stockholders for direct claims against the individual defendants. The complaints did not include any claims against IGEN. In May 2002, the Circuit Court issued an opinion and order dismissing all claims asserted against all of the defendants in both cases. No appeal was filed by the Brown Simpson plaintiff and the decision in that case is now final. The Paskowitz plaintiff filed an appeal to the Court of Special Appeals in Maryland seeking review only for one direct claim. A final decision of the Court of Special Appeals was issued in March 2003 affirming the dismissal of the complaint by the Circuit Court. No appeal was filed and the decisions dismissing all claims in all of these cases are now final. LIMITATION ON THE LIABILITY OF DIRECTORS AND EXECUTIVE OFFICERS BioVeris's certificate of incorporation provides that, to the fullest extent permitted by Delaware law, BioVeris will indemnify its directors and its officers. BioVeris's certificate of incorporation also provides that BioVeris may maintain insurance, at its expense, to protect BioVeris and any of its directors, officers or employees against any such expense, liability or loss whether or not BioVeris would have the power to indemnify that person against such expense, liability or loss under Delaware law. Pursuant to these provisions, BioVeris has entered into indemnity agreements with each of its directors and executive officers and certain of its key employees. BioVeris will obtain director and officer liability insurance, as well as continued coverage under directors' and officers' liability insurance for claims arising from or related to facts or events which occurred at or prior to the completion of the merger. In addition, BioVeris's certificate of incorporation provides that its directors shall not be liable for monetary damages for breach of the directors' fiduciary duty of care as a director, except liability for - any breach of the director's duty of loyalty to BioVeris or its stockholders, - acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, - under section 174 of Delaware law or - any transaction from which a director derived an improper personal benefit. If Delaware law is amended to authorize corporate action further eliminating or limiting personal liability of directors, then the liability of a director shall be eliminated or limited to the fullest extent permitted by Delaware law. 179 PRINCIPAL STOCKHOLDERS The following table sets forth the amount of BioVeris common stock expected to be beneficially owned, upon the completion of the merger, by: - each person or entity known by BioVeris to beneficially own more than 5% of IGEN common stock; - each of BioVeris's directors; - each of BioVeris's named executive officers; and - all of BioVeris's directors and executive officers as a group upon completion of the merger. Unless otherwise stated, BioVeris's expected beneficial ownership is calculated based upon the amount of beneficial ownership of IGEN common stock as of December 18, 2003 and the number of additional shares of BioVeris common stock such person will have a right to receive upon completion of the merger by reason of IGEN stock options held by such person.

To fully understand the actual terms of BioVeris capital stock, you should refer to BioVeris's certificate of incorporation and by-laws, which are filed as exhibits to the registration statement of which this proxy statement/prospectus is a part. AUTHORIZED AND OUTSTANDING CAPITAL STOCK BioVeris's authorized capital stock consists of 100,000,000 shares of common stock, par value $0.001 per share, and 15,000,000 shares of preferred stock, par value $0.001 per share of which 600,000 shares will be designated as series A participating cumulative preferred stock and 1,000 shares will be designated as series B preferred stock. At the close of business on September 24, 2003, approximately 1,000 shares of BioVeris common stock were issued. COMMON STOCK VOTING RIGHTS Each share of BioVeris common stock is entitled to one vote on all matters submitted to a vote of stockholders on which the holders of common stock are entitled to vote. The affirmative vote of holders of: - a majority of the outstanding shares of BioVeris common stock, subject to the requirements of any preferred stock then outstanding, is required to increase or decrease the number of authorized shares of preferred stock (but not below the number of shares thereof then outstanding); - at least 66 2/3% of the voting power of all of BioVeris's shares entitled to vote generally in the election of directors then outstanding, voting together as a single class, is required to alter, amend or repeal or adopt any provision inconsistent with - article V of BioVeris's certificate of incorporation, relating to stockholder action by written consent, - article VII of BioVeris's certificate of incorporation, relating to BioVeris's classified board of directors and the election, appointment and removal of BioVeris's directors, - article VIII of BioVeris's certificate of incorporation, relating to the adoption, alteration, amendment and repeal of BioVeris's by-laws, - the last sentence of article IX of BioVeris's certificate of incorporation, relating to the voting requirements described in this paragraph, - article X of BioVeris's certificate of incorporation, relating to the limitation of personal liability and indemnification of BioVeris's directors, and - section 2.02, relating to calling a special meeting of BioVeris's stockholders, and section 2.07, relating to the notice required for stockholder business and nominations, of BioVeris's by-laws if such action is being taken by vote of the stockholders, and - at least a majority of the voting power of all of BioVeris's shares entitled to vote generally in the election of directors then outstanding, voting together as a single class, is required - to remove any director, which removal may only be effected for cause - to alter, amend or repeal, or adopt any new provision of, BioVeris's certificate of incorporation, except as described above, or - to alter, amend or repeal or adopt new by-laws, except as described above. 181 DIVIDENDS BioVeris's by-laws provide that the BioVeris board of directors may from time to time declare dividends on BioVeris's outstanding shares in accordance with applicable law and BioVeris's certificate of incorporation. OTHER RIGHTS As provided by Delaware law, upon the liquidation, dissolution or winding up of BioVeris, all holders of BioVeris common stock are entitled to share ratably in any assets available for distribution to holders of shares of BioVeris common stock, subject to the preferential rights of any preferred stock then outstanding. Shares of BioVeris common stock are not subject to redemption and do not have preemptive rights to purchase additional shares of BioVeris common stock. PREFERRED STOCK The BioVeris board of directors is authorized to provide for the issuance of shares of preferred stock in one or more series, to establish the number of shares to be included in each such series and to fix the designation, powers, privileges, preferences and rights of the shares of each series (including price, dividend rate, liquidation preference and conversion provisions) and their qualifications, limitations and restrictions. The BioVeris board of directors may, without the approval of holders of BioVeris common stock, issue preferred stock with voting or other rights that could adversely affect the voting power and other rights of the holders of BioVeris common stock and could have anti-takeover effects, including the preferred stock or rights to acquire preferred stock in connection with implementing the stockholder rights agreement. SERIES A PARTICIPATING CUMULATIVE PREFERRED STOCK For a description of the BioVeris series A participating cumulative preferred stock, see "Description of BioVeris Capital Stock -- Rights Agreement." SERIES B PREFERRED STOCK DIVIDENDS. Subject to having legally available funds, at any time (each of the following events is referred to in this proxy/statement prospectus as a dividend event): - BioVeris receives any distribution from MSD, including payments by MSD in connection with the purchase of BioVeris's class C interest in MSD pursuant to the MSD joint venture agreement; or - BioVeris receives any proceeds with respect to a sale, transfer or other disposition of its class C interest in MSD, including payments by MST in connection with the purchase of BioVeris's class C interest in MSD pursuant to the MSD joint venture agreement, the BioVeris board of directors will declare cash dividends on shares of series B preferred stock, payable on or before 60 days after such dividend event, in an amount per share equal to the product of: - the amount of distribution or proceeds received by BioVeris in connection with such dividend event; and - the applicable percentage immediately prior to such dividend event. The applicable percentage as of any given time is, subject to certain adjustments, the quotient of - $7,500, which represents the initial per share purchase price of series B preferred stock, over - BioVeris's class C capital account with MSD as of such given time, as determined in accordance with the MSD limited liability company agreement. 182 For example, assuming BioVeris's class C capital account with MSD is $75 million, - if MSD makes a distribution of $10,000 to BioVeris the BioVeris board of directors will declare a dividend of $1 per share of series B preferred stock outstanding, or - if MST or MSD purchases all of BioVeris's class C interests in MSD for the amount of $10,000,000, the BioVeris board of directors will declare a dividend of $1,000 per share of series B preferred stock outstanding, and the dividend would be payable on or before 60 days after BioVeris receives the MSD distribution or the proceeds of the sale, as the case may be. RANK. The series B preferred stock will rank pari passu with all other classes or series of BioVeris capital stock, except for BioVeris common stock or any other class or series of BioVeris capital stock over which the series B preferred stock has preference or priority in the payment of dividends or in the distribution of assets on any liquidation, dissolution or winding up of BioVeris. VOTING RIGHTS. The holders of series B preferred stock will be entitled to one vote per share and will vote together with the holders of BioVeris common stock as a single class on all matters on which holders of BioVeris common stock are entitled to vote. However, the vote of at least 66 2/3% of the voting power of all shares of series B preferred stock at the time outstanding, voting separately as a class, will be required to effect any approval of or consent by BioVeris to any alteration of the terms of the class C interest in MSD that would adversely affect BioVeris's rights with respect to its class C interest in MSD. In addition, under Delaware law, the series B preferred stock would be entitled to vote as a class on any amendment that would increase or decrease the aggregate number of authorized shares of such class, increase or decrease the par value of the shares of such class, or alter or change the powers, preferences or special rights of the shares of such class so as to affect them adversely. MANDATORY REDEMPTION. Within 30 days after BioVeris receives a liquidation distribution from MSD pursuant to the MSD limited liability company agreement, BioVeris will redeem all outstanding shares of series B preferred stock at a price per share equal to the sum of: - the amount of the liquidation distribution received by BioVeris multiplied by the applicable percentage immediately prior to the receipt of such liquidation distribution by BioVeris; and - any accrued and unpaid dividends. OPTIONAL REDEMPTION. At any time after BioVeris is no longer entitled to receive any distribution from MSD with respect to its class C interest in MSD, BioVeris may, at the option of the BioVeris board of directors, redeem all of the outstanding shares of series B preferred stock at a price of $0.01 per share plus accrued and unpaid dividends. LIQUIDATION RIGHTS. In the event of a liquidation, dissolution or winding up of BioVeris, holders of series B preferred stock will be entitled to receive, before any distribution or payment out of BioVeris's assets is made to the holders of BioVeris common stock, a distribution of $0.01 per share plus accrued and unpaid dividends. After payment in full of $0.01 per share plus any accrued and unpaid dividends, holders of series B preferred stock will not be entitled to any further participation in any distribution of the assets of BioVeris. CLASSIFIED BOARD The BioVeris directors, other than those who may be elected by the holders of any class or series of stock having a preference over BioVeris common stock as to dividends or upon liquidation, are divided into three classes of directors, as nearly equal in number as possible. The BioVeris directors will serve staggered terms so that the initial terms of directors expire either at the first, second or third annual meeting following the effectiveness of BioVeris's certificate of incorporation. Following the initial terms, each class of directors will serve three-year terms. 183 RIGHTS AGREEMENT BioVeris intends to adopt a stockholder rights agreement pursuant to a rights agreement prior to the completion of the merger. Set forth below is a summary of the material provisions expected to be included in the rights agreement. The summary does not include a complete description of all of the terms of the rights agreement. You are urged to read carefully the relevant provisions of the rights agreement, copies of which will be filed with the Securities and Exchange Commission and will be sent to you upon request. See "Where You Can Find More Information." EXERCISABILITY OF RIGHTS Under the rights agreement, one right, referred to in this proxy statement/prospectus as a BioVeris right, attaches to each share of BioVeris common stock outstanding and, when exercisable, entitles the registered holder to purchase from BioVeris one one-thousandth of a share of BioVeris series A participating cumulative preferred stock at an initial exercise price expected to be a multiple of approximately three to five times the expected trading price of BioVeris common stock, subject to customary antidilution adjustments. The BioVeris rights will not become exercisable until the earlier of: - such time as BioVeris learns that a person (other than (1) Mr. Samuel Wohlstadter and Mrs. Nadine Wohlstadter and their affiliates, associates and heirs and any trust or foundation to which they have transferred or may transfer BioVeris common stock, (2) any person that has become, immediately following the completion of the merger, the beneficial owner of more than 10% of BioVeris common stock then outstanding and if such person was not an "Acquiring Person" under IGEN's stockholder rights agreement and if such person does not become the beneficial owner of any additional shares of BioVeris common stock (unless such person does not beneficially own more than 10% of BioVeris common stock then outstanding upon becoming the beneficial owner of such additional shares) and (iii) prior to the completion of the merger, IGEN) has become the beneficial owner of more than 10% of BioVeris common stock then outstanding, such person being referred to in this proxy statement/prospectus as an acquiring person; and - such date as may be designated by the BioVeris board of directors following the commencement of, or the first public disclosure of an intent to commence, a tender offer or exchange offer that would result in a person becoming the beneficial owner of more than 10% of BioVeris common stock then outstanding. "Flip In" Feature. In the event a person becomes an acquiring person, each holder of a BioVeris right, except for such person, will have the right to acquire, upon exercise of each BioVeris right, a number of one one-thousandths of a share of series A participating cumulative preferred stock equal to the number of shares of BioVeris common stock which at the time would have a market price of twice the exercise price. For example, assuming that an exercise price of $40 is in effect on the date that the flip-in feature of the BioVeris rights is exercised, any holder of a BioVeris right, except for the acquiring person or its affiliates or associates, may exercise his or her BioVeris right by paying to BioVeris $40 to receive from BioVeris a number of shares of BioVeris series A preferred stock equal to the number of shares of BioVeris common stock worth $80. "Exchange" Feature. At any time after a person becomes an acquiring person, but prior to a person becoming the beneficial owner of more than 50% of BioVeris common stock then outstanding, the BioVeris board of directors may, at its option, exchange all or some of the BioVeris rights, except for those held by the acquiring person or its affiliates or associates, for consideration per BioVeris right of one-half of the number of shares of BioVeris common stock that would be issuable at such time upon the exercise of each right. Use of the exchange feature means that eligible BioVeris rights holders would not have to pay a purchase price before receiving shares of BioVeris common stock. 184 "Flip Over" Feature. In the event that, after a person becomes an acquiring person: - BioVeris merges into another entity; - another entity merges into BioVeris; or - BioVeris sells 50% or more of its assets or earning power, each holder of a BioVeris right, except for the acquiring person or its affiliates or associates, will have the right to receive, upon exercise of the BioVeris right, instead of one one-thousandth of a share of series A participating cumulative preferred stock, shares of the acquiring company's common stock having a value equal to twice the exercise price of the BioVeris right. Redemption of Rights. At any time prior to the earlier to occur of: - any public announcement that a person has become the beneficial owner of more than 10% of BioVeris common stock then outstanding; and - the tenth anniversary of the adoption of the rights agreement, the BioVeris board of directors may redeem all of the BioVeris rights at a redemption price of $0.001 per right, subject to adjustment. The right to exercise the BioVeris rights will terminate upon redemption, and at that time, each holder of a BioVeris right will have the right to receive only the redemption price for each BioVeris right they hold. Amendment of Rights. At any time before a person becomes an acquiring person the BioVeris board of directors, without the approval of the holders of the BioVeris rights, may amend the terms of the rights agreement. However, at any time after a person becomes an acquiring person, the BioVeris board of directors, without the approval of the holders of the BioVeris rights, may not amend the rights agreement in any manner that would adversely affect the interest of the holders of the BioVeris rights, excluding the interests of such person. Anti-Takeover Effects. The BioVeris rights have anti-takeover effects. Once the BioVeris rights have become exercisable, in most cases the BioVeris rights will cause substantial dilution to a person that attempts to acquire or merge with BioVeris. Accordingly, the existence of the BioVeris rights may deter potential acquirors from making a takeover proposal or a tender offer. The BioVeris rights should not interfere with any merger or other business combination approved by the BioVeris board of directors because BioVeris may redeem the BioVeris rights and because the BioVeris board of directors can amend the rights agreement so that a transaction approved by the BioVeris board of directors would not cause the BioVeris rights to become exercisable. ANTI-TAKEOVER CONSIDERATIONS Delaware law and BioVeris's certificate of incorporation and by-laws contain a number of provisions which may have the effect of discouraging transactions that involve an actual or threatened change of control of BioVeris. For a further description of these provisions, see "Comparison of Rights of Common Stockholders of BioVeris and IGEN," "Description of BioVeris Capital Stock -- Classified Board," "Description of BioVeris Capital Stock -- Preferred Stock" and "Description of BioVeris Capital Stock -- Rights Agreement." 185 COMPARISON OF RIGHTS OF COMMON STOCKHOLDERS OF BIOVERIS AND IGEN Both BioVeris and IGEN are corporations formed under and governed by the laws of the State of Delaware, which is referred to in this proxy statement/prospectus as Delaware law. Accordingly, any differences in the rights of BioVeris and IGEN stockholders are based on the provisions set forth in the certificate of incorporation and by-laws of each company. The following description summarizes the material differences that may affect the rights of BioVeris's stockholders and IGEN stockholders but does not purport to be a complete statement of all those differences, or a complete description of the specific provisions referred to in this summary. The identification of specific differences is not intended to indicate that other equally or more significant differences do not exist. You should read carefully the relevant provisions of BioVeris's certificate of incorporation and by-laws and IGEN's certificate of incorporation and by-laws. BioVeris's certificate of incorporation and by-laws and IGEN's certificate of incorporation and by-laws will be sent to IGEN stockholders upon request. See "Where You Can Find More Information." CAPITALIZATION BIOVERIS BioVeris's authorized capital stock is described above under "Description of BioVeris Capital Stock." IGEN The total authorized shares of capital stock of IGEN consist of: - 50,000,000 shares of IGEN common stock, par value $0.001 per share - 10,000,000 shares of IGEN preferred stock, par value $0.001 per share, of which: - 600,000 shares have been designated as IGEN series A junior participating preferred stock; and - 25,000 shares have been designated as IGEN series B convertible preferred stock. At the close of business on December 8, 2003, approximately 24,983,466 shares of IGEN common stock were issued and outstanding and no shares of IGEN preferred stock were issued and outstanding. The IGEN certificate of incorporation provides that the IGEN board of directors is authorized to provide for the issuance from time to time of shares of IGEN preferred stock in one or more series. The IGEN board of directors is expressly authorized to fix or alter from time to time the designations, powers, preferences and rights of the shares (including price, dividend rate, liquidation preference and conversion provisions) and the qualifications, limitations or restrictions of any wholly unissued series of IGEN preferred stock. The IGEN board of directors may also increase or decrease the number of shares of any series subsequent to the issuance of shares of such series, but not below the number of shares of such series then outstanding. NUMBER, ELECTION, VACANCY AND REMOVAL OF DIRECTORS BIOVERIS BioVeris's certificate of incorporation provides that the total number of its directors, which will be not less than three, is determined from time to time pursuant to a resolution adopted by a majority of the total number of directors that it would have if there were no vacancies on the BioVeris board of directors. BioVeris currently has five directors. BioVeris's certificate of incorporation provides that its directors, other than those who may be elected by the holders of any class or series of stock having a preference over BioVeris common stock as to dividends or upon liquidation, will be divided into three classes, which shall be as nearly equal in number 186 as possible. BioVeris's directors serve staggered terms so that its directors' terms expire either at the first, second or third annual meeting following the effectiveness of BioVeris's certificate of incorporation. Holders of BioVeris common stock are not entitled to vote cumulatively for the election of directors. BioVeris's certificate of incorporation provides that any director may be removed from office only for cause by the affirmative vote of the holders of at least a majority of the voting power of all of BioVeris's shares entitled to vote generally in the election of directors then outstanding, voting together as a single class. No decrease in the number of directors constituting the BioVeris board of directors shall shorten the term of any incumbent director. Subject to any rights of the holders of any class or series of stock having a preference over BioVeris common stock as to dividends or upon liquidation to elect directors under specified circumstances, newly created directorships resulting from any increase in the number of directors and any vacancies on the BioVeris board of directors resulting from death, resignation, disqualification, removal or other cause shall be filled by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum. Any director elected to a newly created or vacant directorships shall hold office until the next succeeding annual meeting of shareholders following his election by the directors, and, if elected by the stockholders at such meeting, shall serve for the remainder of the full term of the class of directors in which the new dictatorship was created or the vacancy occurred and until such director's successor shall have been duly elected and qualified. IGEN The IGEN certificate of incorporation provides that the number of directors of IGEN shall be fixed exclusively by one or more resolutions adopted by the IGEN board of directors. The IGEN board of directors currently has six directors. The IGEN certificate of incorporation provides that the IGEN board of directors will be divided into three classes in accordance with one or more resolutions adopted by the IGEN board of directors. Each director serves for a term ending on the date of the third annual meeting of stockholders following the annual meeting at which the director was elected. Holders of IGEN common stock are not entitled to vote cumulatively for the election of directors. The IGEN certificate of incorporation provides that any director may be removed from office at any time with cause by an affirmative vote of the holders of a majority of the voting power of all the then outstanding shares of voting stock of IGEN entitled to vote at an election of directors. No decrease in the number of directors constituting the board of directors may shorten the term of any incumbent director. Newly created directorships resulting from any increase in the number of directors and any vacancies on the IGEN board of directors resulting from death, resignation, disqualification, removal or other causes shall be filled by the affirmative vote of a majority of the directors then in office, even if the remaining directors do not constitute a quorum. Any director elected to a vacant or newly created directorship shall hold office for the remainder of the full term of the director for which the vacancy was created or occurred and until such director's successor shall have been duly elected and qualified. AMENDMENTS TO CHARTER DOCUMENTS BIOVERIS BioVeris's certificate of incorporation provides that at any time from time to time, any provision contained in its certificate of incorporation may be altered, amended or repealed, and any other provision authorized by Delaware law may be adopted in the manner prescribed by law. The affirmative vote of the holders of at least 66 2/3% of the voting power of all BioVeris's shares entitled to vote generally in the election of directors then outstanding, voting together as a single class, shall be required to alter, amend or repeal or adopt any provision inconsistent with: - article V of BioVeris's certificate of incorporation relating to stockholder action by written consent; - article VII of BioVeris's certificate of incorporation relating to its classified board of directors and the election, appointment and removal of its directors; - article VIII of BioVeris's certificate of incorporation relating to the adoption, alteration, amendment and repeal of its by-laws; 187 - the last sentence of article IX of BioVeris's certificate of incorporation relating to the voting requirements described in this sentence; and - article X of BioVeris's certificate of incorporation, relating to the limitation of personal liability and indemnification of its directors. IGEN The IGEN certificate of incorporation provides that IGEN reserves the right to amend, alter, change or repeal any provision contained in the IGEN certificate of incorporation in the manner prescribed by Delaware law and the certificate of incorporation. The IGEN certificate of incorporation also provides that, notwithstanding any other provisions of the IGEN certificate of incorporation or any provision of law which might otherwise permit a lesser vote or no vote, but in addition to the affirmative vote of the holders of any particular class or series of the then-outstanding shares of IGEN voting stock entitled to vote at an election of directors required by law, the IGEN certificate of incorporation or the terms of any preferred stock, the affirmative vote of at least 66 2/3% of the voting power of all of the then-outstanding shares of IGEN voting stock entitled to vote at an election of directors voting together as a class, shall be required to alter, amend or repeal provisions relating to directors, limitation of liability and amendment of the IGEN certificate of incorporation. AMENDMENTS TO BY-LAWS BIOVERIS BioVeris's certificate of incorporation provides that its by-laws may be altered, amended or repealed and new by-laws may be adopted: - at any annual or special meeting of stockholders, by the affirmative vote of the holders of a majority of the voting power of all BioVeris's shares entitled to vote generally in the election of directors then outstanding, voting together as a single class, except with respect to any proposed alteration, amendment or repeal of, or the adoption of any by-law inconsistent with - section 2.02 of BioVeris's by-laws, relating to calling a special meeting of its stockholders and - section 2.07 of BioVeris's by-laws, relating to the notice required for the stockholder business and nominations, which shall require the affirmative vote of the holders of at least 66 2/3% of the voting power of all BioVeris's shares entitled to vote generally in the election of directors then outstanding, voting together as a single class; or - by the affirmative vote of a majority of the total number of directors that BioVeris would have if there were no vacancies on the BioVeris board of directors. IGEN The IGEN certificate of incorporation and by-laws provide that the IGEN board of directors and IGEN stockholders are each expressly authorized to amend or repeal the IGEN by-laws. Such action by the IGEN stockholders requires the affirmative vote of at least 66 2/3% of the power of all the then outstanding shares of voting stock of IGEN entitled to vote at an election of directors. NOTICE OF STOCKHOLDER ACTIONS BIOVERIS BioVeris's by-laws provide that notice, which states the place, date and hour of the meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered by BioVeris not less than 10 days or more than 60 days, or a shorter or longer period as permitted by law, before the date of the meeting, either personally, by mail or by other lawful means, to each stockholder of 188 record entitled to vote at the meeting. BioVeris's by-laws further provide that the only matters that may be considered and acted upon at a special meeting of stockholders are those matters brought before the meeting through the notice of meeting. Under BioVeris's by-laws, any stockholder of record may submit proposals to be brought before an annual meeting. The notice must contain a brief description of the business desired to be brought before the meeting, the text of the proposal or business, the reasons for conducting such business and any material interest of the stockholder in such proposed business, and the beneficial owners, on whose behalf the proposal is made. If the proposal relates to a director nomination, the notice must also include all information relating to each such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended. To be timely, a stockholder's notice relating to an annual meeting shall be delivered to BioVeris's secretary at BioVeris's principal executive offices not later than the close of business on the 120th day prior to the first anniversary of the preceding year's annual meeting, except that if the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, the notice must be delivered not earlier than the close of business on the 90th day prior to the annual meeting and not later than the close of business on the later of the 60th day prior to the annual meeting or the 10th day following the day on which public announcement of the date of the annual meeting is first made by BioVeris. With respect to BioVeris's 2004 annual meeting, August 28, 2004 has been deemed to be the first anniversary of the preceding year's annual meeting. A stockholder's notice relating to a director nomination for a special meeting shall be delivered to BioVeris's secretary at BioVeris's principal executive offices not earlier than the close of business on the 120th day prior to such special meeting and not later than the close of business on the later of the 90th day prior to the special meeting or the 10th day following the day on which public announcement first made of the date of the special meeting and of the nominees proposed by the BioVeris board of directors to be elected at the special meeting. IGEN The IGEN by-laws provide that a written notice of the place, date, hour and purpose or purposes of each meeting of stockholders shall be given not less than 10 days nor more than 60 days before the date of the meeting to each stockholder entitled to vote at the meeting. The IGEN by-laws further provide that the only matters that may be considered and acted upon at an annual meeting of stockholders are those matters brought before the meeting - through the notice of meeting, - by or at the direction of the IGEN board of directors, or - by a stockholder of IGEN upon proper written notice. Under the IGEN by-laws, a stockholder of IGEN may submit proposals, including director nominations, before an annual meeting of the stockholders by giving timely written notice to IGEN's secretary. The stockholder's notice must set forth, among other things, a brief description of the business the stockholder desires to bring before the annual meeting and the reasons for doing so, the name and address, as they appear on IGEN's books, of the stockholder advancing the proposal, the class and number of shares of IGEN that are beneficially owned by the stockholder, any material interest of the stockholder in the proposal and any other information that is required to be provided by the stockholder pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended, in his capacity as a proponent of a stockholder proposal. If the proposal relates to a director nomination, the notice must also include information regarding the nominee. To be timely, a stockholder's notice must be delivered to or mailed and received at IGEN's principal executive offices not later than 120 days prior to the date of IGEN's proxy statement released to stockholders in connection with the preceding year's annual meeting of stockholders, except that if the date of the current year's annual meeting is changed by more than 30 days from the date contemplated at the time of the previous year's proxy statement, the notice must be received not earlier than the close of business on the 90th day prior to such annual meeting and not later than the 189 close of business on the later of the 60th day prior to the annual meeting, or the 10th day following the date on which public announcement of the date of the annual meeting is first made by IGEN. SPECIAL STOCKHOLDER MEETINGS BIOVERIS BioVeris's by-laws provide that special meetings of its stockholders may be called only by the chairman of the BioVeris board of directors, by BioVeris's chief executive officer, or by the BioVeris board of directors pursuant to a resolution approved by a majority of the total number of directors that BioVeris would have if there were no vacancies. Only business set forth in the notice of the special meeting may be conducted at the special meeting. IGEN The IGEN by-laws provide that special meetings of the stockholders may be called only by the Chairman of the IGEN board of directors, IGEN's chief executive officer or the IGEN board of directors pursuant to a resolution adopted by a majority of the total number of authorized directors (whether or not there are any vacancies in the previously authorized directorships at the time the resolution is presented to the board of directors for adoption). Only matters set forth in the notice of the special meeting or such additional matters as may be determined by the IGEN board of directors may be transacted at the special meeting. LIMITATION OF PERSONAL LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS BIOVERIS BioVeris's certificate of incorporation provides that no director shall be held personally liable to BioVeris or its stockholders for monetary damages for breach of fiduciary duty as a director, except, if required by Delaware law, for liability: - for any breach of a director's duty of loyalty to BioVeris, or BioVeris's stockholders; - for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; - statutory liability for any unlawful payment of dividends or unlawful stock purchase or redemption; or - for any transaction from which the director derived an improper personal benefit. BioVeris's certificate of incorporation provides that to the full extent authorized by Delaware law, it will indemnify any person who was or is made a party or is threatened to be made a party to, or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a BioVeris director or officer or, while serving as a BioVeris director or officer, is or was at BioVeris's request also serving as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against all expense, cost, liability and loss (including attorneys' fees, judgments, fines, amounts paid or to be paid in settlement, court costs, witness fees, excise taxes or penalties arising under the Employee Retirement Income Security Act of 1974, as in effect from time to time incurred in connection with such proceeding) reasonably incurred or suffered by such person in connection therewith. Such indemnification shall continue as to a person who has ceased to be a director or officer and will inure to the benefit of his or her heirs, executors and administrators. BioVeris will pay all expenses incurred in defending any such proceeding in advance of its final disposition. However, if and to the extent Delaware law requires, the payment of such expenses incurred by a director or officer in such person's capacity as a director or officer in advance of the final disposition of a proceeding, will be made only upon delivery to BioVeris of an undertaking, by or on behalf of the 190 director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified. BioVeris may, to the extent authorized by the BioVeris board of directors from time to time, grant rights to indemnification and pay all expenses incurred in defending any proceeding in advance of its final disposition, to any of BioVeris's employees or agents on the same terms and conditions upon which it is required to advance the expenses of BioVeris's directors and officers. BioVeris's certificate of incorporation further provides that the right to indemnification and the advancement of expenses set forth in BioVeris's certificate of incorporation are not exclusive of any other right that any person may have or acquire under any statute, provision of BioVeris's certificate of incorporation, by-laws, agreement, vote of stockholders or disinterested directors or otherwise. No repeal or modification of the provisions of the certificate of incorporation relating to personal liability and indemnification shall in any way diminish or adversely effect the rights of any of the BioVeris directors, officers, employees or agents in respect of any occurrence or matter arising prior to the repeal or modification. BioVeris's certificate of incorporation also provides that BioVeris may maintain insurance, at its expense, to protect BioVeris and any of its directors, officers or employees against any such expense, liability or loss whether or not BioVeris would have the power to indemnify that person against such expense, liability or loss under Delaware law. IGEN The IGEN certificate of incorporation provides that no director shall be held personally liable to IGEN or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability: - for any breach of a director's duty of loyalty to IGEN or its stockholders; - for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; - statutory liability for any unlawful payment of dividends or unlawful stock purchase or redemption; or - for any transaction from which the director derived an improper personal benefit. The IGEN by-laws provide that, to the fullest extent not prohibited by Delaware law, IGEN will indemnify its directors and officers. However, the IGEN by-laws also provide that IGEN is not required to indemnify any director or officer in connection with any proceeding (or part thereof) initiated by such person unless: - such indemnification is expressly required to be made by law; - the proceeding was authorized by IGEN's board of directors; - such indemnification is provided by IGEN, in its sole discretion, pursuant to the powers vested in IGEN under Delaware law; or - such indemnification is required pursuant to any other rights which such person may have. IGEN will advance to any person who is or was threatened to be made a party to or is involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, because he is or was a director or officer of IGEN or is or was serving at the request of IGEN as a director or executive officer of another corporation or of a partnership, joint venture, trust or other enterprise, prior to the final disposition of the proceeding, all expenses incurred by a director or officer in connection with such proceeding upon receipt of an undertaking, by or on behalf of such person, to repay all advanced expenses if it is ultimately determined that such person is not entitled to be indemnified under IGEN's by-laws or otherwise. 191 IGEN will not make any advance to an officer of IGEN (except because the officer is or was a director of IGEN) in any action, suit or proceeding, whether civil, criminal, administrative or investigative, if a determination is reasonably and promptly made - by IGEN's board of directors by a majority vote of a quorum consisting of directors who were not parties to the proceeding, or - if such quorum is not obtainable, or even if obtainable, a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, that the facts known to the decision-making party at the time such determination is made demonstrate clearly and convincingly that the person acted in bad faith or in a manner that the person did not believe to be in or not opposed to the best interests of IGEN. Any repeal or modification of the right to indemnification and advancement of expenses conferred by the IGEN by-laws shall not affect any rights in effect at the time of the alleged occurrence of any action or omission to act that is the cause of any proceeding against any agent of IGEN. The IGEN by-laws further provide that the rights to indemnification and advancement of expenses set forth in the IGEN by-laws are not exclusive of any other right which any person may have or acquire under any statute, provision of the IGEN certificate of incorporation, by-laws, agreement, vote of stockholders or disinterested directors or otherwise. The IGEN by-laws also provide that, to the fullest extent permitted by Delaware law, IGEN, upon approval by the IGEN board of directors, may purchase insurance on behalf of any person required or permitted to be indemnified pursuant to IGEN's by-laws. DIVIDENDS BIOVERIS BioVeris's by-laws provide that its board of directors may from time to time declare dividends on BioVeris's outstanding shares in accordance with the law and its certificate of incorporation. IGEN The IGEN by-laws provide that, subject to the provisions of its certificate of incorporation, if any, the IGEN board of directors may declare dividends pursuant to law at any meeting. VOTING RIGHTS; REQUIRED VOTE FOR AUTHORIZATION OF CERTAIN ACTIONS BIOVERIS Each holder of BioVeris common stock is entitled to one vote for each share held of record and may not cumulate votes for the election of directors. BioVeris is subject to section 203 of the Delaware law which prohibits a publicly held Delaware corporation from consummating a "business combination," except under certain circumstances, with an "interested stockholder" for a period of three years after the date such person became an "interested stockholder" unless: - before such person became an interested stockholder, the board of directors of the corporation approved either the business combination or the transaction in which the interested stockholder became an interested stockholder; - upon the consummation of the transaction that resulted in the interested stockholder becoming such, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding shares held by directors who are also officers of the corporation and shares held by employee stock plans in which employee participants 192 do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or - following the transaction in which such person became an interested stockholder, the business combination is approved by the board of directors of the corporation and authorized at a meeting of stockholders by the affirmative vote of the holders of at least 66 2/3% of the outstanding voting stock of the corporation not owned by the interested stockholder. The term "interested stockholder" generally is defined as a person who, together with affiliates and associates, owns, or, within the prior three years, owned, 15% or more of a corporation's outstanding voting stock. The BioVeris board of directors has taken the action necessary for Section 203 not to apply to Mr. Samuel Wohlstadter and Mrs. Nadine Wohlstadter. The term "business combination" includes mergers, consolidations, asset sales involving 10% or more of a corporation's assets and other similar transactions resulting in a financial benefit to an interested stockholder. Section 203 makes it more difficult for an "interested stockholder" to effect various business combinations with a corporation for a three-year period. A Delaware corporation may "opt out" of section 203 with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or by-laws resulting from an amendment approved by holders of at least a majority of the outstanding voting stock. Neither the BioVeris certificate of incorporation nor the BioVeris by-laws contain any such provision. IGEN Each holder of IGEN common stock is entitled to one vote for each share held of record and may not cumulate votes for the election of directors. IGEN is also subject to section 203 of the Delaware law as described above. Neither the IGEN certificate of incorporation nor the IGEN by-laws contain a provision to "opt out" of section 203 of the Delaware law. 193 SHARES ELIGIBLE FOR FUTURE SALE BioVeris estimates that 26,728,705 shares of BioVeris common stock will be issued in the merger, based on the number of shares of IGEN common stock and IGEN stock options and warrants outstanding on December 18, 2003 and the exchange ratio for IGEN common stock specified in the merger agreement. BioVeris common stock issued in the merger will not be subject to any restrictions on transfer arising under the Securities Act of 1933, except for shares issued to any person who is an "affiliate" of IGEN, BioVeris or Roche at the time the merger is submitted for vote for purposes of Rule 145 under the Securities Act. 194 APPROVAL OF BIOVERIS 2003 STOCK INCENTIVE PLAN On September 24, 2003, the BioVeris board of directors adopted, subject to IGEN stockholder approval, the BioVeris 2003 stock incentive plan. Up to 5,300,000 shares of BioVeris common stock (subject to adjustment in the event of stock splits and other similar events) may be issued pursuant to awards granted under the BioVeris 2003 stock incentive plan. The IGEN board of directors believes that the future success of BioVeris depends, in large part, upon the ability of BioVeris to maintain a competitive position in attracting, retaining and motivating key personnel. ACCORDINGLY, THE IGEN BOARD OF DIRECTORS BELIEVES APPROVAL OF THE BIOVERIS 2003 STOCK INCENTIVE PLAN IS IN THE BEST INTERESTS OF BIOVERIS AND ITS STOCKHOLDERS AND UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE APPROVAL OF THE BIOVERIS 2003 STOCK INCENTIVE PLAN AND THE RESERVATION OF 5,300,000 SHARES OF BIOVERIS COMMON STOCK FOR ISSUANCE THEREUNDER. DESCRIPTION OF THE BIOVERIS 2003 STOCK INCENTIVE PLAN The following is a brief summary of the BioVeris 2003 stock incentive plan, a copy of which is attached as Annex 16 to this proxy statement/prospectus. The following summary is qualified in its entirety by reference to the BioVeris 2003 stock incentive plan. TYPES OF AWARDS The BioVeris 2003 stock incentive plan provides for the grant of incentive stock options intended to qualify under Section 422 of the Code, non-statutory stock options, restricted stock awards and other stock-based awards, including the grant of shares based upon certain conditions, the grant of securities convertible into BioVeris common stock and the grant of stock appreciation rights, all of which are collectively referred to in this proxy statement/prospectus as awards. Incentive Stock Options and Non-statutory Stock Options. Optionees receive the right to purchase a specified number of shares of BioVeris common stock at a specified option price and subject to such other terms and conditions as are specified in connection with the option grant. Subject to the limitations described below, options may be granted at an exercise price which may not be less than the fair market value of the BioVeris common stock on the date of grant. Under present law, incentive stock options and options intended to qualify as performance-based compensation under Section 162(m) of the Code may not be granted at an exercise price less than 100% of the fair market value of the BioVeris common stock on the date of grant (or less than 110% of the fair market value in the case of incentive stock options granted to optionees holding more than 10% of the voting power of BioVeris). Options may not be granted for a term in excess of ten years. The BioVeris 2003 stock incentive plan permits the following forms of payment of the exercise price of options: - payment by cash, check or, at the discretion of the BioVeris board of directors, a "cashless exercise" through a broker; - surrender to BioVeris of shares of BioVeris common stock; - to the extent permitted by applicable law and the BioVeris board of directors, delivery to BioVeris of a promissory note; - any other lawful means; or - any combination of these forms of payment. The BioVeris 2003 stock incentive plan provides that on the day following each annual meeting of BioVeris stockholders each non-employee director will receive an automatic grant of options to purchase 4,000 shares of BioVeris common stock. In addition, any person who is appointed or elected as a non- employee director at any other time will receive an automatic grant of options to purchase 4,000 shares of BioVeris common stock on the date of such appointment or election. Each grant will have an exercise 195 price equal to fair market value on the date of grant and will vest in full on the first anniversary of the grant date. Restricted Stock Awards. Restricted stock awards entitle recipients to acquire shares of BioVeris common stock, subject to the right of BioVeris to repurchase all or part of such shares from the recipient in the event that the conditions specified in the applicable award are not satisfied prior to the end of the applicable restriction period established for such award. Other Stock-Based Awards. Under the BioVeris 2003 stock incentive plan, the BioVeris board of directors has the right to grant other awards based upon the BioVeris common stock having such terms and conditions as the BioVeris board of directors may determine, including the grant of shares based upon certain conditions, the grant of securities convertible into BioVeris common stock and the grant of stock appreciation rights. ELIGIBILITY TO RECEIVE AWARDS Employees, officers, directors, consultants and advisors (and any individuals who have accepted an offer for employment) of BioVeris and its subsidiaries and of other business ventures in which BioVeris has a significant interest are eligible to be granted awards under the BioVeris 2003 stock incentive plan. Under present law, however, incentive stock options may only be granted to employees of BioVeris and its subsidiaries. The maximum number of shares with respect to which awards may be granted to any participant under the BioVeris 2003 stock incentive plan may not exceed 500,000 shares per calendar year. PLAN BENEFITS As of November 30, 2003, approximately 306 persons were eligible to receive awards under the BioVeris 2003 stock incentive plan, including BioVeris's executive officers and non-employee directors. The granting of awards under the BioVeris 2003 stock incentive plan is discretionary, and BioVeris cannot now determine the number or type of awards to be granted in the future to any particular person or group. ADMINISTRATION The BioVeris 2003 stock incentive plan is administered by the BioVeris board of directors. The BioVeris board of directors has the authority to adopt, amend and repeal the administrative rules, guidelines and practices relating to the BioVeris 2003 stock incentive plan and to interpret the provisions of the BioVeris 2003 stock incentive plan. Pursuant to the terms of the BioVeris 2003 stock incentive plan, the BioVeris board of directors may delegate authority under the BioVeris 2003 stock incentive plan to one or more committees or subcommittees of the BioVeris board of directors. To the extent permitted by applicable law, the BioVeris board of directors may delegate to one or more executive officers the power to grant awards to employees or officers who are not executive officers of BioVeris, provided that the BioVeris board of directors will fix the terms of the awards to be granted by such executive officers (including the exercise price of such awards, which may include a formula by which the exercise price will be determined) and the maximum number of shares subject to awards that the executive officers may grant. The BioVeris board of directors authorized the executive compensation committee to administer certain aspects of the BioVeris 2003 stock incentive plan, including the granting of options to executive officers, and has authorized, to the extent permitted by applicable law, the non-officer stock option committee the power to grant awards to employees of BioVeris who are not executive officers of BioVeris, subject to certain limitations set by the BioVeris board of directors. Subject to any applicable limitations contained in the BioVeris 2003 stock incentive plan, the BioVeris board of directors, the executive compensation committee, or the non-officer stock option committee, as the case may be, selects the recipients of awards and determines: - the number of shares of BioVeris common stock covered by options and the dates upon which such options become exercisable; - the exercise price of options; 196 - the duration of options (which may not exceed 10 years); - the number of shares of BioVeris common stock subject to any restricted stock or other stock-based awards and the terms and conditions of such awards, including conditions for repurchase, issue price and repurchase price. The BioVeris board of directors is required to make appropriate adjustments in connection with the BioVeris 2003 stock incentive plan and any outstanding awards to reflect stock splits, stock dividends, recapitalizations, spinoffs and other similar changes in capitalization. The BioVeris 2003 stock incentive plan also contains provisions addressing the consequences of any "reorganization event," which is defined as: - any merger or consolidation of BioVeris with or into another entity as a result of which all of the BioVeris common stock is converted into or exchanged for the right to receive cash, securities or other property or - any exchange of all of the BioVeris common stock for cash, securities or other property pursuant to a share exchange transaction. Upon the occurrence of a reorganization event, all outstanding options are to be assumed, or substituted for, by the acquiring or succeeding corporation. However, if the acquiring or succeeding corporation does not agree to assume, or substitute for, outstanding options, then the BioVeris board of directors must either accelerate the options to make them fully exercisable prior to consummation of the reorganization event or provide for a cash out of the value of any outstanding options. Upon the occurrence of a reorganization event, the repurchase and other rights of BioVeris under each outstanding restricted stock award will inure to the benefit of the acquiring or succeeding corporation. The BioVeris board of directors will specify the effect of a reorganization event on each award at the time the award is granted. If any award expires or is terminated, surrendered, canceled or forfeited, the unused shares of BioVeris common stock covered by such award will again be available for grant under the BioVeris 2003 stock incentive plan, subject, however, in the case of incentive stock options, to any limitations under the Code. AMENDMENT OR TERMINATION No award may be made under the BioVeris 2003 stock incentive plan after September 24, 2013, but awards previously granted may extend beyond that date. The BioVeris board of directors may at any time amend, suspend or terminate the BioVeris 2003 stock incentive plan, except that no award designated as subject to Section 162(m) of the Code by the BioVeris board of directors after the date of such amendment shall become exercisable, realizable or vested (to the extent such amendment was required to grant such award) unless and until such amendment shall have been approved by BioVeris's stockholders. If IGEN stockholders do not approve the adoption of the BioVeris 2003 stock incentive plan, the BioVeris 2003 stock incentive plan will not go into effect, and BioVeris will not grant any awards under the BioVeris 2003 stock incentive plan. In such event, the BioVeris board of directors will consider whether to adopt alternative arrangements based on its assessment of the needs of BioVeris. FEDERAL INCOME TAX CONSEQUENCES The following is a summary of the U.S. Federal income tax consequences that generally will arise with respect to awards granted under the BioVeris 2003 stock incentive plan and with respect to the sale of BioVeris common stock acquired under the BioVeris 2003 stock incentive plan. This summary is based on the Federal tax laws in effect as of the date of this proxy statement. Changes to these laws could alter the tax consequences described below. 197 INCENTIVE STOCK OPTIONS In general, a participant will not recognize taxable income upon the grant or exercise of an incentive stock option. Instead, a participant will recognize taxable income with respect to an incentive stock option only upon the sale of BioVeris common stock acquired through the exercise of the option, or ISO stock. The exercise of an incentive stock option, however, may subject the participant to the alternative minimum tax. Generally, the tax consequences of selling ISO stock will vary depending on the date on which it is sold. If the participant sells ISO stock more than two years from the date the option was granted, or the grant date, and more than one year from the date the option was exercised, or the exercise date, then the participant will recognize long-term capital gain in an amount equal to the excess of the sale price of the ISO stock over the exercise price. If the participant sells ISO stock prior to satisfying the above waiting periods, referred to as a disqualifying disposition, then all or a portion of the gain recognized by the participant will be ordinary compensation income and the remaining gain, if any, will be a capital gain. This capital gain will be a long-term capital gain if the participant has held the ISO stock for more than one year prior to the date of sale. If a participant sells ISO stock for less than the exercise price, then the participant will recognize capital loss in an amount equal to the excess of the exercise price over the sale price of the ISO stock. This capital loss will be a long-term capital loss if the participant has held the ISO stock for more than one year prior to the date of sale. NON-STATUTORY STOCK OPTIONS As in the case of an incentive stock option, a participant will not recognize taxable income upon the grant of a non-statutory stock option. Unlike the case of an incentive stock option, however, a participant who exercises a non-statutory stock option generally will recognize ordinary compensation income in an amount equal to the excess of the fair market value of the BioVeris common stock acquired through the exercise of the option, or NSO stock on the exercise date over the exercise price. With respect to any NSO stock, a participant will have a tax basis equal to the exercise price plus any income recognized upon the exercise of the option. Upon selling NSO stock, a participant generally will recognize capital gain or loss in an amount equal to the difference between the sale price of the NSO stock and the participant's tax basis in the NSO stock. This capital gain or loss will be a long-term gain or loss if the participant has held the NSO stock for more than one year prior to the date of the sale. RESTRICTED STOCK AWARDS A participant will not recognize taxable income upon the grant of a restricted stock award unless the participant makes a Section 83(b) election. If the participant makes a valid Section 83(b) election within 30 days of the date of the grant, then the participant will recognize ordinary compensation income, for the year in which the award is granted, in an amount equal to the difference between the fair market value of the BioVeris common stock at the time the award is granted and the purchase price paid for the BioVeris common stock. If a valid Section 83(b) election is not made, then the participant will recognize ordinary compensation income, at the time that the forfeiture provisions or restrictions on transfer lapse, in an amount equal to the difference between the fair market value of the BioVeris common stock at the time of such lapse and the original purchase price paid for the BioVeris common stock. The participant will have a tax basis in the BioVeris common stock acquired equal to the sum of the price paid and the amount of any ordinary compensation income recognized. Upon the disposition of the BioVeris common stock acquired pursuant to a restricted stock award, the participant will recognize a capital gain or loss equal to the difference between the sale price of the BioVeris common stock and the participant's tax basis in the BioVeris common stock. This capital gain or loss will be a long-term capital gain or loss if the shares are held for more than one year. 198 OTHER STOCK-BASED AWARDS The tax consequences associated with any other stock-based award granted under the BioVeris 2003 stock incentive plan will vary depending on the specific terms of such award. Among the relevant factors are whether or not the award has a readily ascertainable fair market value, whether or not the award is subject to forfeiture provisions or restrictions on transfer, the nature of the property to be received by the participant under the award and the participant's holding period and tax basis for the award or underlying BioVeris common stock. TAX CONSEQUENCES TO BIOVERIS The grant of an award under the BioVeris 2003 stock incentive plan generally will have no tax consequences to BioVeris. Moreover, in general, neither the exercise of an incentive stock option nor the sale of any BioVeris common stock acquired under the BioVeris 2003 stock incentive plan will have any tax consequences to BioVeris. BioVeris or its parent or subsidiary, as the case may be, generally will be entitled to a business-expense deduction, however, with respect to any ordinary compensation income recognized by a participant under the BioVeris 2003 stock incentive plan, including in connection with a restricted stock award or as a result of the exercise of a non-statutory stock option or a disqualifying disposition. Any such deduction will be subject to the limitations of Section 162(m) of the Code. AWARDS UNDER THE BIOVERIS 2003 STOCK INCENTIVE PLAN In connection with the transfer of IGEN employees to BioVeris, the BioVeris board of directors has approved the grant, subject to the approval of the BioVeris 2003 stock incentive plan by IGEN stockholders and the completion of the merger, to BioVeris employees of options to purchase 100 shares of BioVeris common stock. As a result of the foregoing, upon completion of the merger, options for approximately 23,500 shares of BioVeris common stock would be outstanding. Each option will have an exercise price equal to fair market value on the date of grant and will vest in full on the first anniversary of the date that the merger is completed. 199 LEGAL MATTERS The legality of the BioVeris common stock being offered by this proxy statement/prospectus will be passed upon for BioVeris by Cravath, Swaine & Moore LLP.

All statements in this proxy statement/prospectus that are not historical facts, including statements about markets and potential markets, market growth for diagnostic products, potential impact of competitive products, BioVeris's expectations regarding future royalties and revenue, the potential market for products in development, prospects for future business arrangements with third parties, financing plans, the outcome of the merger, the description of BioVeris's plans and objectives for future operations, assumptions underlying such plans and objectives, the need for and availability of additional capital are hereby identified as "forward-looking statements." The words "may," "should," "will," "expect," "could," "anticipate," "believe," "estimate," "plan," "intend" and similar expressions have been used to identify certain of the forward-looking statements. In this proxy statement/prospectus BioVeris has based these forward-looking statements on management's current expectations, estimates and projections and they are subject to a number of risks, uncertainties and assumptions that could cause actual results to differ materially from those described in the forward-looking statements. Such forward-looking statements should, therefore, be considered in light of various important factors, including those set forth in this proxy statement/prospectus. The following important factors are among those that may cause actual results to differ materially from BioVeris's forward-looking statements: - the outcome of the merger; - changes in BioVeris's strategy and business plan, including its plans for the clinical diagnostics, biodefense, life science and industrial markets and other healthcare opportunities; - BioVeris's ability to develop and introduce new or enhanced products, including incorporating unit dose cartridges and completion of pending negotiations for novel centrifuge technologies; - BioVeris's ability to enter into new collaborations on favorable terms, if at all; - BioVeris's ability to expand the distribution and increase sales of existing products; - the demand for rapid testing products in each of BioVeris's markets; - BioVeris's ability to expand its manufacturing capabilities or find a suitable manufacturer on acceptable terms or in a timely manner, including the completion of pending negotiations for contract manufacturing of one of BioVeris's instruments; - BioVeris's ability to develop its selling, marketing and distribution capabilities; - BioVeris's and its licensees' ability to obtain FDA and other governmental approvals for its and their clinical testing products; - the ability of BioVeris's licensees to effectively develop and market products based on the technology BioVeris licenses to them; - domestic and foreign governmental and public policy changes, particularly related to healthcare costs, that may affect new investments and purchases made by BioVeris's customers; - availability of financing and financial resources in the amounts, at the times and on the terms required to support BioVeris's future business; - rapid technological developments in each of BioVeris's markets and its ability to respond to those changes in a timely, cost-effective manner; - any potential future disputes regarding the scope, permitted use and other material terms of BioVeris's license agreements, including those with Roche and MSD; - the outcome of the litigation and arbitration between Applied Biosystems and Roche; - protection and validity of BioVeris's patent and other intellectual property rights; 203 - statements regarding relationships between BioVeris and the related companies; and - changes in general economic, business and industry conditions. These forward-looking statements are found at various places throughout this proxy statement/ prospectus and the other documents incorporated by reference, including, but not limited to, IGEN's Annual Report on Form 10-K for the year ended March 31, 2003, including any amendments. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this proxy statement/prospectus. Neither BioVeris nor IGEN undertake any obligation to publicly update or release any revisions to these forward-looking statements to reflect events or circumstances after the date of this proxy statement/prospectus or to reflect the occurrence of unanticipated events. The foregoing list sets forth some, but not all, of the factors that could have an impact upon BioVeris's and IGEN's ability to achieve results described in any forward-looking statements. Investors are cautioned not to place undue reliance on such statements that speak only as of the date made. Investors also should understand that it is not possible to predict or identify all such factors and that this list should not be considered a complete statement of all potential risks and uncertainties. Investors should also realize that if underlying assumptions prove inaccurate or unknown risks or uncertainties materialize, actual results could vary materially from BioVeris's and IGEN's projections. 204 BIOVERIS CORPORATION INDEX TO CONSOLIDATED FINANCIAL STATEMENTS PAGE ---- Independent Auditors' Report................................ F-2 Consolidated Balance Sheets................................. F-3 Consolidated Statements of Operations....................... F-4 Consolidated Statements of Cash Flows....................... F-5 Consolidated Statements of Net Investment by IGEN........... F-6 Notes to Consolidated Financial Statements.................. F-7 F-1 INDEPENDENT AUDITORS' REPORT To the Board of Directors of BioVeris Corporation: We have audited the accompanying consolidated balance sheets of BioVeris Corporation and subsidiaries (the Company), a component of IGEN International, Inc., as of March 31, 2002 and 2003, and the related consolidated statements of operations, cash flows and net investment by IGEN International, Inc. for each of the three years in the period ended March 31, 2003. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. The accompanying consolidated financial statements have been prepared from the separate records maintained by the Company and may not necessarily be indicative of the conditions that would have existed or the results of operations if the Company had been operated as an unaffiliated company. Portions of certain expenses represent allocations made from home-office items applicable to the Company as a whole. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of March 31, 2002 and 2003, and the results of its operations and its cash flows for each of the three years in the period ended March 31, 2003, in conformity with accounting principles generally accepted in the United States of America. /s/ Deloitte & Touche LLP McLean, Virginia September 25, 2003 F-2 BIOVERIS CORPORATION CONSOLIDATED BALANCE SHEETS (IN THOUSANDS) MARCH 31, ----------------- SEPTEMBER 30, 2002 2003 2003 ------- ------- ------------- (UNAUDITED) ASSETS CURRENT ASSETS: Accounts receivable, net.................................. $ 2,768 $ 5,434 $ 5,058 Inventory................................................. 4,462 5,448 5,145 Prepaid expenses and other................................ 1,234 2,286 1,300 ------- ------- ------- Total current assets................................... 8,464 13,168 11,503 EQUIPMENT AND LEASEHOLD IMPROVEMENTS, NET................... 6,429 6,456 5,793 OTHER NONCURRENT ASSETS: Investment in joint venture............................... 6,243 9,164 14,790 Other..................................................... 382 372 363 ------- ------- ------- Total assets........................................... $21,518 $29,160 $32,449 ======= ======= ======= LIABILITIES AND NET INVESTMENT BY IGEN CURRENT LIABILITIES: Accounts payable and accrued expenses..................... $ 4,438 $ 4,758 $ 3,794 Accrued wages and benefits................................ 2,359 3,170 2,018 Deferred revenue.......................................... 418 507 551 Capital lease obligations................................. 56 -- -- ------- ------- ------- Total current liabilities.............................. 7,271 8,435 6,363 DEFERRED REVENUE............................................ 96 60 26 ------- ------- ------- Total liabilities...................................... 7,367 8,495 6,389 COMMITMENTS AND CONTINGENCIES............................... -- -- -- NET INVESTMENT BY IGEN...................................... 14,151 20,665 26,060 ------- ------- ------- Total liabilities and net investment by IGEN........... $21,518 $29,160 $32,449 ======= ======= ======= See notes to consolidated financial statements.

F-6 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company and Basis of Presentation -- On July 24, 2003, IGEN International, Inc. (IGEN) and Roche Holding Ltd (Roche) jointly announced that they had reached definitive agreements pursuant to which Roche will acquire IGEN and IGEN will simultaneously distribute the common stock of a new company, BioVeris Corporation (the Company), to its stockholders (the merger). The transaction will occur in the following steps: - IGEN will restructure its operations so that the Company, a newly formed, wholly-owned subsidiary of IGEN, will assume IGEN's biodefense, life science and industrial product lines as well as IGEN's opportunities in the clinical diagnostics and healthcare fields and will own IGEN's intellectual property, IGEN's equity interest in Meso Scale Diagnostics, LLC. (MSD), cash and certain other rights and licenses currently held by IGEN; and - A wholly-owned subsidiary of Roche will merge with and into IGEN, as a result of which IGEN will become a wholly-owned subsidiary of Roche and the Company will become an independent, publicly-traded company owned by IGEN stockholders. Simultaneously with the completion of the merger, certain ongoing commercial agreements between the Company and certain affiliates of Roche will become effective. The obligations of the parties to complete the merger are subject to certain conditions, including the adoption of the merger agreement by IGEN stockholders, the receipt by IGEN of a solvency opinion substantially to the effect that the Company will not be insolvent after giving effect to the merger and related transactions and the execution and delivery of the ongoing commercial agreements, and that Roche will have loaned IGEN up to $214 million, such loan remaining the obligation of IGEN following the completion of the merger. All cash on hand at IGEN will be transferred to BioVeris as part of the restructuring. The Company was organized as IGEN Integrated Healthcare, LLC, a Delaware limited liability company, on June 6, 2003, and converted into BioVeris Corporation, a newly formed Delaware corporation on September 22, 2003. IGEN Integrated Healthcare, LLC was, and the Company is, a wholly-owned subsidiary of IGEN. The assets and businesses of the Company have historically been owned and operated by IGEN. The accompanying financial statements have been prepared and are presented as if the Company had been operating as a separate entity using IGEN's historical cost basis in the assets and liabilities and including the historical operations of the businesses and assets to be transferred to the Company from IGEN as part of the restructuring. Accordingly, IGEN's net investment in the Company is shown in lieu of stockholders' equity in the accompanying consolidated balance sheets. IGEN holds all cash in a centralized treasury and has provided all of the necessary funding for the operations of the Company. Accordingly, no cash is reflected on the accompanying consolidated balance sheets. IGEN has the ability and intent to fund the businesses being transferred to BioVeris until such time as the merger is completed. For each of the periods presented in the consolidated financial statements, the Company was fully integrated with IGEN and these financial statements reflect the application of certain estimates and allocations. The Company's consolidated statements of operations include all revenues and costs that are directly attributable to the Company's businesses. In addition, certain expenses of IGEN have been allocated to the Company using various assumptions. These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs). General and administrative salaries have been allocated primarily based upon an estimate of actual time spent on the businesses of the Company. Facilities costs and centralized administrative services have been allocated based upon a percentage of total product sales F-7 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) as well as a percentage of total headcount. Management believes these allocation methodologies and estimations are reasonable based upon the nature of the related expenses and management's knowledge of the level of effort and space required to support the businesses of the Company. Allocated expenses of $13.2 million, $19.2 million, $20.5 million, $10.2 million, and $9.2 million are included in selling, general and administrative expenses in the accompanying consolidated statements of operations for the fiscal years ended March 31, 2001, 2002 and 2003, and the six months ended September 30, 2002 and 2003, respectively. These allocated expenses were derived from total IGEN selling, general and administrative expenses of $16.8 million, $24.0 million, $24.7 million, $12.3 million and $12.0 million for the fiscal years ended March 31, 2001, 2002 and 2003, and the six months ended September 30, 2002 and 2003, respectively. The financial information included herein may not reflect the financial position, results of operations and cash flows of the Company in the future or what they would have been had BioVeris been operating as a stand-alone entity in the past. On or before the date of the merger, IGEN Europe, Inc. and IGEN International, K.K. will become wholly-owned subsidiaries of the Company, therefore the consolidated financial statements include the accounts of the Company and these subsidiaries. All significant intercompany transactions and balances have been eliminated. Estimates -- In addition to the estimates noted above, the preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Concentration of Credit Risk -- During the years ended March 31, 2001, 2002 and 2003, and the six months ended September 30, 2002 and 2003, agencies of the U.S. government accounted for 2%, 11%, 26%, 19% and 17% of total revenue, respectively, and 11%, 43% and 29% of total accounts receivable as of March 31, 2002 and 2003 and September 30, 2003, respectively. Allowance for Doubtful Accounts -- The Company maintains reserves on customer accounts where estimated losses may result from the inability of its customers to make required payments. These reserves are determined based on a number of factors, including the current financial condition of specific customers, the age of accounts receivable balances and historical loss rates. Inventory -- Inventory is recorded at the lower of cost or market using the first-in, first-out method and consists of the following: MARCH 31, --------------- SEPTEMBER 30, 2002 2003 2003 ------ ------ ------------- (UNAUDITED) (IN THOUSANDS) Finished goods......................................... $2,041 $2,234 $2,019 Work in process........................................ 1,149 869 425 Raw materials.......................................... 1,272 2,345 2,701 ------ ------ ------ Total................................................ $4,462 $5,448 $5,145 ====== ====== ====== Equipment and Leasehold Improvements -- Equipment and leasehold improvements are carried at cost, less accumulated depreciation and amortization. Depreciation on equipment, which includes lab instruments and furniture, is computed over the estimated useful lives of the assets, generally three to five years, using straight-line or accelerated methods. Leasehold improvements are amortized on a straight-line basis over the life of the lease. During the year ended March 31, 2002, the Company changed its F-8 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) depreciation method for certain equipment from an accelerated method to straight-line. The impact of this change was not material to the Company's financial position or results of operations. Equipment and leasehold improvements consist of the following: MARCH 31, ------------------ SEPTEMBER 30, 2002 2003 2003 -------- ------- ------------- (UNAUDITED) (IN THOUSANDS) Lab instruments and equipment....................... $ 7,761 $ 6,274 $ 6,628 Office furniture and equipment...................... 7,492 5,847 6,234 Leasehold improvements.............................. 2,864 3,618 3,773 -------- ------- -------- 18,117 15,739 16,635 Accumulated depreciation and amortization........... (11,688) (9,283) (10,842) -------- ------- -------- Total............................................. $ 6,429 $ 6,456 $ 5,793 ======== ======= ======== Capitalized Software Costs -- Software development costs incurred after technological feasibility is established are capitalized in accordance with Statement of Financial Accounting Standards (SFAS) No. 86, "Accounting for the Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed." To date, software development has been substantially completed concurrently with the establishment of technological feasibility, and accordingly, no costs have been capitalized to date. Evaluation of Long-Lived Assets -- The Company evaluates the potential impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. In evaluating the recoverability of an asset, management's policy is to compare the carrying amount of an asset with the projected undiscounted future cash flow. Management believes no impairment of these assets exists as of March 31, 2002 and 2003 and September 30, 2003. Warranty Reserve -- The Company warrants its products against defects in material and workmanship for one year after sale and records estimated future warranty costs at the time revenue is recognized. A reserve for future warranty claims is recorded based upon management's review of historical claims, supplemented by expectations of future costs. The Company also offers extended warranty arrangements to customers, for which related costs are recorded as incurred. Warranty reserve activity is as follows: YEAR ENDED SIX MONTHS ENDED MARCH 31, 2003 SEPTEMBER 30, 2003 -------------- ------------------ (UNAUDITED) (IN THOUSANDS) BALANCE, BEGINNING OF PERIOD.......................... $ 170 $ 250 Provisions recorded................................. 1,278 743 Actual costs incurred............................... (1,198) (743) ------- ----- BALANCE, END OF PERIOD................................ $ 250 $ 250 ======= ===== Fair Value of Financial Instruments -- The carrying amounts of the Company's financial instruments, which include accounts receivable, accounts payable and accrued expenses, approximate their fair value due to their short maturities. Revenue Recognition -- The Company derives revenue principally from three sources: product sales, royalty income and contract fees. F-9 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) Product sales revenue is recognized when persuasive evidence of an arrangement exists, the price to the buyer is fixed and determinable, collectibility is reasonably assured and the product is shipped to the customer thereby transferring title and risk of loss. For instrument sales, the instrument and the related installation are considered to be separate elements under EITF 00-21. Revenue is recognized for the instrument upon shipment and is recognized for the installation when complete based upon the residual value method. For instrument and reagent sales, there is no option of return and refund, only the option to repair or replace. Other than the installation required for the instruments, there are no contingencies, allowances or other post-sale obligations. For instrument leases, the instrument rental and related minimum reagent purchases are considered to be separate elements under EITF 00-21 and, accordingly, the sales price is allocated to the two elements based upon their relative fair values. Instrument rental revenue is recognized ratably over the life of the lease agreements and the related reagent revenue is recognized upon shipment. Revenue associated with extended warranty arrangements is recognized over the term of the extended warranty contract. Royalty income is recorded when earned, based on information provided by licensees. Revenue from services performed under contracts is recognized when obligations under the contract have been satisfied. The satisfaction of obligations may occur over the term of the underlying customer contract, if the contract is based on the achievement of certain "milestones," or may occur at the end of the underlying customer contract, if based only upon delivery of the final work product. Research and Development -- Research and development costs are expensed as incurred. Foreign Currency -- Gains and losses from foreign currency transactions, such as those resulting from the settlement of foreign receivables or payables, are included in the results of operations as incurred. These amounts were not material during the years ended March 31, 2001, 2002 and 2003 and the six months ended September 30, 2002 and 2003. Income Taxes -- The assets and businesses of the Company have historically been owned and operated by IGEN. The Company was not a separate legal or tax entity and the operating results of the Company were included in IGEN's consolidated Federal and state income tax returns. As a result, income taxes have been calculated as if the Company was a stand-alone entity filing a separate tax return. Stock-Based Compensation -- The Company has elected to follow the recognition and measurement principals of Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations in accounting for employee stock options and, accordingly, will not recognize compensation cost for options granted under its 2003 stock incentive plan whose exercise price equaled the market value of a share of the underlying common stock on the date of grant. The Company did not have any stock option grants. The following table illustrates the effect on net loss and net loss per share as if IGEN had applied the fair value recognition provisions of SFAS No. 123, "Accounting for Stock-Based Compensation," as amended by SFAS No. 148, "Accounting for Stock- Based Compensation -- Transition and Disclosure -- An Amendment of SFAS No. 123," to stock-based F-10 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) employee compensation and the resulting costs attributable to the Company's employees were reflected in the consolidated financial statements: SIX MONTHS ENDED YEARS ENDED MARCH 31, SEPTEMBER 30, ------------------------------ ------------------------- 2001 2002 2003 2002 2003 -------- -------- -------- ----------- ----------- (UNAUDITED) (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS) Net loss, as reported.............. $(30,724) $(49,150) $(50,894) $(26,851) $(23,817) Deduct: Total stock-based employee compensation charge determined under fair value method..........

The net loss, as adjusted, and net loss per share, as adjusted, disclosed above is not representative of the effects on net loss and net loss per share on an as adjusted basis in future years, as future years will include grants by the Company of options for the Company common stock. In addition, upon completion of the merger, all options for IGEN common stock will be canceled. The fair value of options for IGEN common stock was estimated at the date of grant using a Black-Scholes option pricing model with the following assumptions: SIX MONTHS YEARS ENDED ENDED MARCH 31, SEPTEMBER 30, ------------------ ------------- 2001 2002 2003 2002 2003 ---- ---- ---- ----- ----- (UNAUDITED) Expected dividend yield............................... 0% 0% 0% 0% 0% Expected stock price volatility....................... 71% 71% 68% 69% 65% Risk-free interest rate............................... 5.5% 4.3% 3.4% 3.8% 2.3% Expected option term (in years)....................... 5 5 5 5 5 Based on this calculation, the weighted average fair value of options granted was $9.66, $15.68, $20.56, $21.37 and $21.09, during the years ended March 31, 2001, 2002 and 2003 and the six months ended September 30, 2002 and 2003, respectively. Pro Forma Net Loss Per Share -- The Company uses SFAS No. 128, "Earnings per Share," for the calculation of basic and diluted earnings per share. For all periods presented, unaudited pro forma net loss per share is based on the number of common shares expected to be outstanding upon completion of the merger and related transactions. Interim Financial Statements -- The accompanying unaudited interim consolidated financial statements as of September 30, 2003 and 2002 have been prepared in conformity with accounting principles generally accepted in the United States of America. In the opinion of management, all adjustments consisting only of normal recurring adjustments considered necessary for a fair presentation have been included. The Company's consolidated results of operations for any period are not necessarily indicative of the results for the full year or for any other period. F-11 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) New Accounting Standards -- In November 2002, the Financial Accounting Standards Board (FASB) issued Interpretation No. 45, "Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Guarantees of Indebtedness of Others," or FIN 45. FIN 45 establishes new disclosure and liability recognition requirements for direct and indirect guarantee with specified characteristics. The initial recognition and measurement provisions of FIN 45 are applicable on a prospective basis to guarantees issued or modified after December 31, 2002. The disclosure requirements in FIN 45 are effective for both annual and interim periods ending after December 15, 2002. The Company adopted FIN 45 as of March 31, 2003 and the implementation did not have a material effect on its financial position, results of operation or cash flows. In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation -- Transition and Disclosure -- an amendment of SFAS No. 123" (SFAS 148). SFAS 148 amends SFAS 123, "Accounting for Stock-Based Compensation" (SFAS 123), to provide alternative methods of voluntarily transitioning to the fair value based method of accounting for stock-based employee compensation. SFAS 148 also amends the disclosure requirements of SFAS 123 to require disclosure of the method used to account for stock-based employee compensation and the effect of the method on reported results in both annual and interim financial statements. This pronouncement is effective for both annual and interim periods beginning after December 15, 2002. The Company has elected to follow the recognition and measurement principles of Accounting Principles Board Opinion No. 25, "Accounting For Stock Issued to Employees," in its accounting for employee stock options. In accordance with SFAS 148, the Company has adopted the annual and interim period disclosure requirements. In January 2003, the FASB issued Interpretation No. 46, "Consolidation of Variable Interest Entities," or FIN 46. FIN 46 provides guidance on variable interest entities such as the MSD joint venture and the framework through which an enterprise assesses consolidation of a variable interest entity. The Company will adopt FIN 46 as of January 1, 2004 and has determined that MSD qualifies as a variable interest entity based upon the following rationale: - The Company has provided substantially all of MSD's funding since inception through capital contributions consisting of class B and C non-voting equity interests. Such funding is not considered "at risk" as the investments do not participate significantly in the profits of MSD given their stated return rates. As such the "at risk" equity of MSD is insufficient to absorb MSD's expected future losses. - The Company holds 31% of the voting rights in MSD while providing 100% of MSD's funding, and the Company is thereby considered to be involved in all of MSD's activities as defined under FIN 46. As the merger and related transactions do not change the design of or ownership interests in MSD in such a manner that could affect the status of MSD as a variable interest entity or the Company as the primary beneficiary, the Company does not believe they are deemed to be events that would require reassessment of the Company's previous determination that MSD qualifies as a variable interest entity under FIN 46. Accordingly, beginning January 1, 2004 and continuing subsequent to the completion of the merger and related transactions, the Company will consolidate the financial results of MSD. Under the transition guidance of FIN 46 because MSD was created before February 1, 2003, the Company will measure the assets, liabilities and noncontrolling interests of MSD as of January 1, 2004 for purposes of the initial consolidation. The amounts of the assets, liabilities and noncontrolling interests will be reflective of their respective carrying amounts had FIN 46 been effective when the Company first met the conditions to be the primary beneficiary of MSD upon MSD's inception in 1995. Such carrying amounts are expected to equal MSD's recorded values, which as of September 30, 2003, were approximately $17.0 million, $1.8 million and $10,000, respectively. As the Company has historically recorded and will continue to F-12 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) record approximately 100% of MSD's losses, it is anticipated that upon implementation of FIN 46, the consolidated net assets of MSD will approximate the book value of the Company's investment in joint venture. As such, consolidation accounting will require certain reclassifications within the Company's consolidated financial statements, but it is not expected to materially effect its financial position or net loss. The required balance sheet reclassifications will reclassify the amounts formerly recorded on a "net" basis as investment in joint venture to be reflected on a "gross" basis primarily as cash, accounts receivable, inventory, fixed assets, accounts payable and accrued expenses. The required statement of operations reclassifications will reclassify the amounts formerly recorded on a "net" basis as equity in loss of joint venture to be reflected on a "gross" basis primarily as revenue, product costs, research and development expenses and selling, general and administrative expenses. See Note 4 for the historical financial information of MSD." In April 2003, the FASB issued SFAS No. 149, "Amendment of SFAS No. 133 on Derivative Instruments and Hedging Activities" (SFAS 149). SFAS 149 amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities under SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." The amendments set forth in SFAS 149 require that contracts with comparable characteristics be accounted for similarly. SFAS 149 is generally effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. The implementation of SFAS 149 did not have a material effect on the Company's financial position, results of operations or cash flows. In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity" (SFAS 150). SFAS 150 establishes standards regarding the classification and measurement of certain financial instruments with characteristics of both liabilities and equity. SFAS 150 is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. The implementation of SFAS 150 did not have a material effect on the Company's financial position, results of operations or cash flows. 2. LICENSE AND RESEARCH AGREEMENTS IGEN granted a license to bioMerieux, for the development and worldwide-development, use, manufacture and sale of ECL-based nucleic acid test systems on a co-exclusive basis for certain segments of the clinical diagnostics market and on a non-exclusive basis for certain segments of the life science market. Among other things, the agreement provides for royalty payments to IGEN on product sales and for product supply arrangements between the parties. This agreement will be assigned to the Company in connection with the restructuring. Royalty income from bioMerieux of $276,000, $252,000, $236,000, $80,000 and $74,000 has been recognized in the accompanying consolidated financial statements for the years ended March 31, 2001, 2002, and 2003, and the six months ended September 30, 2002 and 2003, respectively. IGEN granted a license to Eisai, for the manufacture and market of a class of ORIGEN-based diagnostic systems on an exclusive basis for the clinical diagnostics market in Japan. The agreement provides for royalty payments to IGEN on product sales. In 2002, IGEN and Eisai executed an extension of the license under which the license became non-exclusive in July 2003. This agreement will be assigned to the Company in connection with the restructuring. Royalty income from Eisai of $609,000, $798,000, $871,000, $433,000 and $466,000 has been recognized in the accompanying consolidated financial statements for the years ended March 31, 2001, 2002 and 2003, and the six months ended September 30, 2002 and 2003, respectively. F-13 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) 3. STOCK OPTION PLANS In September 2003, the board of directors of the Company adopted, subject to IGEN stockholder approval, the BioVeris 2003 Stock Incentive Plan (Stock Plan). Up to 5.3 million shares of common stock of the Company (subject to adjustment in the event of stock splits and other similar events) may be issued pursuant to awards granted under the Stock Plan. The Stock Plan provides for the grant of incentive stock options intended to qualify under Section 422 of the Internal Revenue Code of 1986, as amended, non-statutory stock options, restricted stock awards and other stock-based awards, including the grant of shares based upon certain conditions, the grant of securities convertible into common stock of the Company and the grant of stock appreciation rights (collectively, Awards). Employees, officers, directors, consultants and advisors, including any individuals who have accepted an offer for employment, of the Company and its subsidiaries are eligible to be granted awards under the Stock Plan. Incentive stock options may only be granted to employees of the Company and its subsidiaries. Approval of the Stock Plan requires the affirmative vote of the IGEN stockholders and no awards have been granted. In August 2000, IGEN granted 75,000 non-qualified stock options under its 1994 Stock Option Plan in connection with a consulting arrangement for services to be provided to it. The consultant is also the sole owner of Meso Scale Technologies (MST) and is a son of IGEN's and the Company's chairman and chief executive officer (see Note 4). As a result of certain events in fiscal 2002 and pursuant to Financial Accounting Standards Board Interpretation No. 44, "Accounting for Certain Transactions Involving Stock Compensation -- an Interpretation of APB Opinion No. 25" and EITF 96-18, "Accounting for Equity Instruments That Are Issued To Other Than Employees For Acquiring, or in Conjunction with Selling, Goods or Services," IGEN began recognizing expense on a monthly basis as the options are earned and vest, based upon fair value calculated in accordance with the Black-Scholes option pricing model. Changes in the fair value of the unvested options will result in changes in future expense recognition. The options vest ratably over a five-year period through August 2005. As the consulting services were provided to the the Company's businesses, compensation expense of $219,000, $386,000, $184,000 and $261,000 has been reflected in the accompanying financial statements for the years ended March 31, 2002 and 2003 and the six months ended September 30, 2002 and 2003, respectively. The Company did not have any stock option grants. Certain detailed stock option disclosures related to options granted under IGEN stock option plans have been omitted from these notes to consolidated financial statements as all such options will be canceled in connection with the merger and related transactions and the holder of any such options will have the right to receive for each share covered by such option cash from Roche equal to the excess of $47.25 over the exercise price of such option and one share of the Company's common stock. In connection with such cancelation of IGEN stock options and the payment of the merger consideration for each share covered by IGEN stock options, the Company will record an allocated noncash compensation charge for each IGEN stock option. In calculating the compensation charge associated with the merger and related transactions, the Company will apply the guidance of FIN 44 for employee stock options and SFAS 123 for nonemployee stock options. Under FIN 44 guidance, if the post-spinoff value of BioVeris exceeds the pre-spinoff value, both vested and unvested employee stock options at the merger date will be included in the calculation of the compensation charge. Alternatively, if the post-spinoff value of BioVeris is less than or equal to the pre-spinoff value, only the unvested employee stock options that have been accelerated will be included in the calculation of the compensation charge. Under SFAS 123 guidance, the compensation charge will be calculated based upon the incremental fair value for the nonemployee stock options resulting from the F-14 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) merger. As of March 31, 2003, there were options to acquire approximately 1.6 million shares of IGEN common stock, with a weighted average exercise price of $18.16 per share. 4. MESO SCALE DIAGNOSTICS JOINT VENTURE MSD is a joint venture formed by MST and IGEN in 1995. MSD was formed for the development, manufacture, marketing and sale of products utilizing a combination of MST's multi-array technology together with IGEN's technology. MST is a company established and wholly-owned by Jacob Wohlstadter, a son of IGEN's and the Company's chairman and chief executive officer. In August 2001, IGEN amended the MSD joint venture agreement, the MSD limited liability company agreement and certain license and other agreements with MSD and MST to continue the MSD joint venture and entered into various related agreements (the MSD agreements). An independent committee of the IGEN board of directors, with the advice of independent advisors and counsel, negotiated and approved the MSD agreements. As part of the restructuring, IGEN will transfer its equity interest in MSD to the Company and will assign the MSD agreements to the Company. MSD manufactures, markets and sells instrument systems, including the Sector HTS and the Sector PR, which combine MST's multi-array technology and IGEN's ECL technology. The Sector HTS is an ultra high throughput drug discovery system engineered for applications such as high throughput screening and large-scale proteomics. The Sector PR is a smaller system designed for benchtop applications such as assay development, research in therapeutic areas, cellular biology and medium throughput screening. MSD also manufactures and markets a line of its own reagents, assays and plates that are used on these systems. MSD commenced product sales in October 2002. The original MSD joint venture agreement and related funding provisions established IGEN's initial ownership interest in MSD at 50% of MSD's total voting equity interests. In August 2001, IGEN and MST agreed to continue the MSD joint venture and entered into a number of amendments to the MSD agreements. In connection with these amendments, IGEN's voting equity interest in MSD was reduced to 31%. These amendments were the result of extensive negotiations between the Joint Venture Oversight Committee (JVOC), on behalf of IGEN, on the one hand, and MST and MSD, on the other hand. The original MSD joint venture agreement provided formulas to allocate IGEN's funding to either IGEN's initial capital contribution consisting of class A voting equity interests and class B non-voting equity interests, or class C non-voting preferred equity interests. Under those formulas, costs relating to organizational and on-going operating expenses other than those directly related to the MSD research program, as defined in the MSD agreements, or MSD's use of IGEN's infrastructure and personnel were primarily allocated to class C interests. Based on the amount and kind of funding that had been provided by IGEN to MSD during the first five years of the joint venture, IGEN believed that it was entitled to class A voting equity interests in MSD equal to at least 50% of the total class A interests in MSD. MST's view was that IGEN's funding in the early years of the joint venture was mostly for costs for which IGEN would be entitled to class C interests. As a result, MST believed IGEN was entitled to significantly less than 50% of the class A voting equity interests in MSD. As part of the resolution as to how the class A voting interests and class C interests would be allocated, the parties, after negotiation, agreed that IGEN was entitled to a 31% class A voting equity interest in MSD and a proportional amount of class B non-voting equity interests. As part of the negotiations that led to IGEN's acceptance of this amount of voting equity interest, IGEN and MST agreed to various amendments to the MSD agreements that were beneficial to IGEN, such as the opportunity, following the expiration or termination of the MSD joint venture agreement, to receive royalties on the licenses that IGEN had granted to MSD and MST, as well as limits on the current and future intellectual property of IGEN that MSD and MST would be entitled to use following the expiration or termination of the MSD joint venture agreement. The JVOC also considered the fact that the class C non-voting preferred interests had a priority return as compared to the class A voting equity interests. F-15 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) Prior to the amendments to the MSD agreements in August 2001, IGEN expensed all investments in MSD immediately upon contribution. As such, no recorded book value existed for IGEN's investment in MSD and consequently, no additional accounting was required in response to the JVOC's agreement that IGEN's voting equity interest in MSD would be fixed at 31% and not at 50%. Under the MSD agreements, IGEN's funding commitment was based on an annual budget of MSD approved by the JVOC, a committee of the IGEN board of directors consisting of independent directors. The JVOC approved funding for MSD by IGEN for the period from January 1, 2003 to November 30, 2003 in an amount of $20.6 million, subject to a permitted variance of 15%. As of September 30, 2003, IGEN's remaining funding commitment to MSD was $5.4 million. IGEN's remaining funding commitment may be satisfied in part through in-kind contributions of scientific and administrative personnel and shared facilities. For the years ended March 31, 2001, 2002 and 2003 and the six months ended September 30, 2002 and 2003, IGEN made total contributions to MSD of $8.3 million, $19.6 million, $20.5 million, $10.8 million and $15.3 million, respectively. During the year ended March 31, 2002, IGEN transferred certain equipment and leasehold interests to MSD in the amount of $839,000, which amount is included in the in-kind contributions to MSD in such year. Separate from and in addition to IGEN's remaining funding commitment under the MSD agreements for the period from January 1, 2003 to November 30, 2003, the Company has agreed to make a final capital contribution of $37.5 million to MSD following the completion of the merger. Of the $37.5 million, Samuel Wohlstadter, IGEN's and the Company's chairman and chief executive officer, will fund any amount in excess of $30.0 million (including any interim funding provided by IGEN as described in the next sentence) through the purchase of the Company's series B preferred stock that economically mirror the class C interests in MSD to be held by BioVeris. In addition, in the event the merger is not completed prior to December 1, 2003, IGEN has agreed to provide continued interim funding to MSD, payable monthly on the first day of each month commencing on December 1, 2003 until the earlier to occur of completion of the merger or termination of the merger agreement. The monthly funding will equal approximately $1.7 million, which is 1/12th of IGEN's aggregate funding commitment under the MSD budget for 2003 approved by the JVOC. Any interim funding will reduce the amount of the Company's final capital contribution following the completion of the merger. After the restructuring, and subject to MSD's and MST's right to buy BioVeris's interests in MSD, the Company will replace IGEN as a member of MSD and will hold a 31% voting equity interest in MSD and be entitled to a preferred return on $72.2 million of the funds previously invested by IGEN in MSD through September 30, 2003 and on all additional funds invested by IGEN and the Company thereafter. This preferred return would be payable out of a portion of both future profits and certain third-party financings of MSD, generally before any payments are made to other equity holders. Although MST owns the remaining 69% voting equity interest in MSD, the Company generally has the right to approve significant MSD governance matters. In exercising this right, an independent committee of the Company board of directors must consider the Company's interests and the interests of the Company's stockholders while also taking into consideration the interests of MSD. IGEN and MST are the sole members of MSD, and each holds one seat on MSD's two-member board of managers. After the restructuring, Dr. Richard Massey, IGEN's and the Company's president and chief operating officer, will be the Company's representative on the MSD board of managers and will also serve as the treasurer and secretary of MSD. The other member of the MSD board of managers is Mr. Jacob Wohlstadter, who is the sole owner of MST and serves as president and chief executive officer of MSD. Under the terms of one of the MSD agreements, IGEN granted to MSD a worldwide, perpetual, exclusive license (with certain exceptions) to IGEN's technology, including ECL technology, for use in F-16 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) MSD's research program, defined in the MSD agreements. If the Company ceases to be a member of MSD, it will become entitled to receive royalty payments from MSD on all products developed and sold by MSD using the Company's patents. MST holds a worldwide, perpetual, non-exclusive sublicense from MSD for certain non-diagnostic applications of the Company's technology. The Company is entitled to receive royalty payments from MST on any products developed and sold by MST using the patents the Company will receive as part of the restructuring. During the term of the MSD joint venture agreement, MSD is IGEN's and MST's exclusive means of conducting the MSD research program, and IGEN is obligated to refrain from developing or commercializing any products, processes or services that are related to the MSD research program in the diagnostic field, as defined for purposes of the MSD agreements, or to MSD's research technologies as described in the MSD agreements, subject to certain exceptions. After the expiration or termination of the MSD joint venture agreement, IGEN or the Company, as applicable, may not use the improvements granted to it by MSD if doing so would compete with MSD in the diagnostic field or use research technologies defined in the MSD agreements. As part of the merger agreement and related transaction agreements, the Company, IGEN and MSD agreed that the MSD joint venture agreement will expire on the later of November 30, 2003, or the earlier of the date of the completion of the merger and related transactions or the termination of the merger agreement. In addition, in accordance with the MSD agreements, MST and MSD have the right to terminate the MSD joint venture agreement prior to its expiration under certain circumstances, including breach of IGEN's obligations, including IGEN's funding obligations to MSD, MSD's termination of Mr. Jacob Wohlstadter's employment (other than for cause or disability), if Mr. Jacob Wohlstadter is entitled to terminate his employment agreement for good reason (as defined in his employment agreement) or upon a change in control of IGEN, as defined. MSD and Mr. Jacob Wohlstadter have each agreed that the merger and related transactions will not constitute a change in control for purposes of the MSD agreements. Upon the expiration of the MSD joint venture upon the completion of the merger, MSD and MST will have the right to purchase BioVeris's interest in MSD for a purchase price equal to fair market value (to be determined in accordance with the provisions and procedures set forth in the MSD agreements, which shall include a determination by appraisers if the parties are unable to agree on fair market value) minus a discount factor of 7.5%. If MSD or MST exercises this right, it will be required to pay the Company the outstanding purchase price plus simple (cumulated, not compounded) interest at the fixed annual rate of 0.5% over the prime rate in effect on the date that MSD or MST, as the case may be, elects to purchase the interests. The purchase price is payable over time in installments equal to the sum of 5% of MSD net sales, as determined in accordance with the MSD agreements, and 20% of the net proceeds realized by MSD from the sale of its debt or equity securities in any third-party financing after the date of the sale the Company's interest in MSD. As security for the payment obligation, the Company will hold a security interest in the interests in MSD that are being purchased. MST or MSD, as the case may be, may repay all or any part of the outstanding purchase price plus accrued interest at any time and from time to time without penalty. Following the expiration of the MSD joint venture agreement, many of the licenses and other arrangements with MSD and MST assigned to the Company will continue indefinitely. Following the expiration or termination of the MSD joint venture agreement, MSD will be entitled to continue to lease certain facilities and related equipment from BioVeris (including laboratory facilities located in BioVeris's corporate headquarters) pursuant to the terms of the existing sublease agreements F-17 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) with MSD. The term of each sublease will expire one day prior to the expiration of the prime lease for that facility. Each sublease agreement provides that, subject to certain exceptions, BioVeris must exercise all available extension rights under the prime lease. Following termination or expiration of the MSD joint venture agreement, each of MSD and BioVeris may unilaterally terminate any or all of the subleases by providing at least 18 months prior written notice of termination. If BioVeris elects to terminate a sublease for a facility, MSD may elect, notwithstanding any termination of the sublease, to remain in the subleased facility after the 18-month period expires for any period of time selected by MSD, but not longer than one day prior to the expiration of the prime lease (including any extensions of the prime lease). After a notice of termination of a sublease has been sent, MSD will be required to pay its pro rata share of all rental and other expense incurred by BioVeris under the prime lease. MSD and MST may elect, if either exercises its right to purchase BioVeris's interests in MSD, to have its rental and expense payment obligations for the 18-month period included in the purchase price of those interests in MSD. MSD has an employment agreement with Mr. Jacob Wohlstadter, its president and chief executive officer, the current term of which runs through November 30, 2004 and provides for a salary at the annual rate of $250,000 through November 30, 2003. Thereafter, the salary is to be increased as agreed to by MSD and Mr. Jacob Wohlstadter. In addition, Mr. Jacob Wohlstadter is also eligible to receive, at the discretion of the JVOC of the IGEN or BioVeris board of directors, as the case may be, an annual cash bonus in an amount not to exceed 20% of his annual salary. During year ended December 31, 2003, Mr. Jacob Wohlstadter is expected to receive $250,000 from his employment at MSD. If MSD terminates the employment agreement without cause, or Mr. Jacob Wohlstadter terminates the employment agreement for good reason (which includes a "change in control" of BioVeris, as defined), Mr. Jacob Wohlstadter will be entitled to receive, in addition to salary and pro rata bonus and adjustments earned through the 60th day following the notice of termination, an amount equal to from 3 to 12 times (depending on the reason for the termination) the monthly pro rata salary, bonus and adjustments in effect at the time of the termination. Under the employment agreement Mr. Jacob Wohlstadter is also entitled to receive a gross-up for any "parachute" excise tax imposed on payments made or benefits provided pursuant to the agreement. In addition, upon such a termination prior to the expiration of the MSD joint venture agreement, MSD and MST shall have a joint right to purchase the Company's interest in MSD on terms described above. The Company will be responsible for all amounts payable, costs incurred and other obligations under the employment agreement prior to the termination of the Company's funding obligation to MSD following the completion of the merger, which generally are expected to be paid out of IGEN's funding commitment to MSD and the Company's one-time contribution to MSD. MSD and Mr. Jacob Wohlstadter have each agreed that the merger and related transactions will not constitute a change in control for purposes of the MSD agreements and the employment agreement. The Company will also indemnify Mr. Jacob Wohlstadter against certain liabilities, including liability from the MSD joint venture relating to the period of IGEN's or the Company's involvement with MSD. In addition, the Company will be obligated under the MSD agreements to indemnify each board member or officer of MSD with respect to any action taken by such person prior to the termination of the MSD joint venture agreement by reason of the fact that such person is or was a board member or an officer of MSD. With respect to such indemnification obligations, there are no pending or known matters covered by these indemnification provisions that would have a material effect on the Company's financial position or results of operations. Since inception of the MSD joint venture, the equity method has been utilized to account for this investment. Prior to July 1, 2001, given MSD's status as a development stage enterprise without having established technological feasibility of its intended product offering, the Company considered its investments in MSD to be other than temporarily impaired. As such, any residual investment book value, after recognizing the Company's share of MSD losses in accordance with the equity method, was written off upon contribution. All expenses related to the MSD investment prior to July 1, 2001 were recorded as F-18 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) research and development expenses based upon the significance and character of the MSD losses as substantially all contributions supported research and development initiatives. Beginning on July 1, 2001, taking into account the progress made by MSD in the development of its products, the Company determined that no additional impairments were required to its prospective contributions and thus ceased writing-off the amount of its contributions to MSD that were in excess of MSD's losses. At that time, MSD was transitioning from a development stage entity to a commercial enterprise and milestones establishing the continued viability of MSD were first achieved in the quarter ended September 30, 2001. For example, prototypes had been assembled demonstrating product feasibility, and MSD was anticipating initial product launch in approximately one year. As a result of this transition, MSD's expenses were no longer primarily research and development. Accordingly, since July 1, 2001, the Company has recorded only its proportionate share of MSD losses, representing approximately 100% of MSD's losses, for each respective period as equity in loss of joint venture consistent with accounting for equity method investments. MSD-related research and development expenses totaled $8.3 million ($5.9 million of equity method losses and $2.4 million of impairment losses) and $2.4 million ($2.2 million of equity method losses and $200,000 of impairment losses) for the years ended March 31, 2001 and 2002, respectively. MSD-related losses included in equity in loss of joint venture were $10.9 million and $17.6 million for the years ended March 31, 2002 and 2003, respectively. During the years ended March 31, 2001, 2002 and 2003 and the six months ended September 30, 2002 and 2003, operating costs allocated to MSD by the Company in connection with shared personnel and facilities totaled $5.6 million, $11.4 million, $11.9 million, $5.8 million and $4.1 million, respectively. Since July 1, 2001, these allocated operating costs reduced certain operating costs and expenses and increased Equity in Loss of Joint Venture in the accompanying consolidated statements of operations. The Company's investment in joint venture totaled $6.2 million and $9.2 million at September 30, 2002 and 2003, respectively. See Note 1 for discussion of consolidation accounting of the MSD investment as of October 1, 2003. Summarized financial information for MSD is as follows: SIX MONTHS ENDED YEARS ENDED MARCH 31, SEPTEMBER 30, -------------------------- ----------------- 2001 2002 2003 2002 2003 ------ ------- ------- ------ ------- (UNAUDITED) (IN THOUSANDS) Revenue............................... $ -- $ -- $ 3,247 $ 314 $ 3,000 Operating expenses.................... 6,185 13,560 21,357 9,930 12,804 Net loss.............................. 6,185 13,541 18,215 9,577 9,798 MARCH 31, ---------------- SEPTEMBER 30, 2002 2003 2003 ------ ------- ------------- (UNAUDITED) (IN THOUSANDS) Current assets......................................... $4,571 $ 5,685 $10,334 Total assets........................................... 8,305 11,904 16,965 Current liabilities.................................... 885 2,226 1,631 Total liabilities...................................... 931 2,226 1,781 Total members' equity.................................. 7,374 9,678 15,184 F-19 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) 5. INCOME TAXES The Company's operating results historically have been included in IGEN's consolidated Federal and state income tax returns. As a result, income taxes have been calculated as if the Company was a stand-alone entity filing a separate tax return. For the years ended March 31, 2001, 2002 and 2003, and for the six months ended September 30, 2002 and 2003, the Company recorded no Federal or state income tax expense and did not owe or pay Federal or state income tax as calculated by applying statutory rates. In connection with the merger and related transactions, Roche will be acquiring all of the historical net operating loss and tax credit carryforwards of IGEN. The Company however, will be assuming IGEN's historical cost basis in the assets and liabilities transferred to the Company from IGEN. Deferred income tax assets and liabilities have been computed for differences between financial reporting and tax bases of the assets and liabilities assumed that will result in taxable or deductible amounts in the future. The computation of deferred income taxes is based on enacted tax laws and rates applicable to periods in which the differences are expected to affect the taxable income of the Company after the completion of the merger. The approximate tax effects of temporary differences that will give rise to the Company's deferred tax assets are as follows: MARCH 31, ----------------- 2002 2003 ------- ------- (IN THOUSANDS) Deferred tax assets: Accruals and reserves....................................... $ 468 $ 551 Deferred revenue............................................ 198 219 Equipment and leasehold improvements........................ 976 1,304 Investment in affiliate..................................... 1,791 1,954 Other....................................................... 45 (238) ------- ------- Total deferred tax asset.................................. 3,478 3,790 Less: valuation allowance................................... (3,478) (3,790) ------- ------- Net deferred tax asset................................. $ -- $ -- ======= ======= A valuation allowance equal to the total net deferred tax assets has been provided as of March 31, 2002 and 2003 as it is more likely than not that deferred tax assets will not be realized. The increase in the valuation allowance on the deferred tax asset was $2.6 million and $300,000 for the years ended March 31, 2002 and 2003, respectively. As a result of state income taxes and a valuation allowance, the provision for income taxes recorded in the accompanying consolidated statements of operations differs from the amount that would have resulted by applying the U.S. Federal income tax statutory rate. 6. EMPLOYEE SAVINGS PLAN IGEN has an Employee Savings Plan intended to qualify under Sections 401(a) and 401(k) of the Internal Revenue Code of 1986, as amended, and subject to the Employee Retirement Income Security Act of 1974, as amended. IGEN made discretionary contributions of $275,000, $459,000, $544,000, $140,000 and $138,000 for the years ended March 31, 2001, 2002 and 2003, and the six months ended September 30, 2002 and 2003, respectively, attributable to BioVeris employees. As part of the restructuring, the Company will assume all liabilities with respect to this plan. The Company intends to establish a 401(k) employee benefit plan similar in nature to the plan formerly provided to its employees by IGEN. F-20 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) 7. RELATED PARTIES The Company's chairman and chief executive officer, Mr. Samuel Wohlstadter, is the principal and controlling stockholder, a director and the chief executive officer of each of Wellstat Biologics Corporation, Wellstat Therapeutics Corporation, Hyperion Catalysis International (Hyperion) and Proteinix Corporation (Proteinix). The Company's president and chief operating officer, Dr. Richard Massey, is also a director of Hyperion and a less than 10% stockholder in Proteinix. These companies are therefore considered the Company's affiliates for the purpose of this discussion. After the completion of the merger and related transactions, the Company will have shared services arrangements with each of these affiliated companies. These shared services include accounting and finance, human resources and other administrative services, as well as facility related costs and services. Shared services costs allocated to these companies totaled $1.9 million, $1.3 million, $1.0 million, $500,000 and $600,000 for the years ended March 31, 2001, 2002 and 2003, and the six months ended September 30, 2002 and 2003, respectively, which reduced certain operating costs and expenses for the respective periods. Amounts allocated to these affiliated companies are calculated and billed monthly based upon costs incurred by the Company and are determined through allocation methods that include time-spent and square footage utilized. Amounts due from affiliated companies under the shared services arrangements were $94,000, $228,000 and $294,000 at March 31, 2002 and 2003 and September 30, 2003, respectively, which were paid subsequent to each respective period-end. IGEN has licensed certain diagnostic technologies from affiliated companies and has licensed certain pharmaceutical technologies to affiliated companies. No royalties have ever been earned or accrued under these license agreements. These license agreements will be assigned to the Company in connection with the restructuring. 8. COMMITMENTS AND CONTINGENCIES Capital Leases -- IGEN is obligated under capital lease agreements for certain equipment. These leases will be assigned to the Company in connection with the restructuring and will expire during the year ending March 31, 2004. The aggregate discounted lease payments are recorded as a liability, and the fair market value of the related leased assets are capitalized and amortized over the estimated useful lives of the assets. Total assets capitalized pursuant to such agreements were approximately $350,000 and $224,000 and $224,000 at March 31, 2002 and 2003 and September 30, 2003, respectively, with accumulated amortization totaling approximately $307,000, $220,000 and $224,000 at March 31, 2002 and 2003 and September 30, 2003, respectively. Operating Leases -- IGEN leased office, laboratory and manufacturing facilities pursuant to operating leases expiring at various times from fiscal 2004 through fiscal 2010. These leases will be assigned to the Company in connection with the restructuring. Rent expense for these operating leases totaled approximately $2.4 million, $2.6 million, $2.9 million, $1.4 million and $1.4 million for the years ended March 31, 2001, 2002 and 2003, and the six months ended September 30, 2002 and 2003, respectively. F-21 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) At March 31, 2003, the future minimum operating lease payments are as follows: OPERATING LEASE YEARS ENDED MARCH 31, PAYMENTS --------------------- -------------- (IN THOUSANDS) 2004........................................................ $ 2,635 2005........................................................ 2,650 2006........................................................ 2,683 2007........................................................ 2,735 2008........................................................ 2,807 2009 and thereafter......................................... 5,921 ------- Total..................................................... $19,431 ======= License Payment -- In connection with the merger and related transactions, the Company has committed to pay certain affiliates of Roche a fee of $50 million after the completion of the merger for a worldwide, non-exclusive license under patents that cover certain PCR inventions. Tax Allocation Contingency -- Pursuant to the tax allocation agreement among Roche, a subsidiary of Roche, IGEN and the Company, the Company may be required to pay IGEN up to $20 million to the extent that the average of the high and low market capitalization for the Company on the first day of trading of the Company's common stock after the completion of the merger exceeds a specified threshold. 9.

The cost of these modules had F-23 BIOVERIS CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (INCLUDING INFORMATION APPLICABLE TO UNAUDITED PERIODS) previously been recorded as a fixed asset and depreciated over their estimated useful life, and should have been recorded as product costs upon shipment and sale. The Company determined that the adjustment did not have a material impact on fiscal 2002 or prior period financial statements and accordingly, did not revise such financial statements. Of the $1.1 million adjustment, $200,000 is related to fiscal 2002 and the remaining $900,000 is related to prior fiscal years (approximately $400,000 and $500,000 in fiscal 2001 and 2000, respectively). (2) See Note 4 of the consolidated financial statements for a description of the recording of losses under the equity method of accounting related to the MSD investment. (3) Based on the number of shares of the Company common stock expected to be outstanding upon completion of the merger and related transactions. The sum of quarterly per share amounts may not be equal to per share amounts reported for year-to-date periods due to changes in the number of shares outstanding and the effects of rounding for each period.

SECTION 5.03 Further Assurances. The parties agree that if, after the completion of the Restructuring, either party or its affiliates holds Assets which by the terms hereof or of the Merger Agreement were intended to be assigned and transferred to, or retained by, the other party, such party shall, at its expense, promptly assign and transfer or cause to be assigned and transferred such Assets to the other party, and the parties agree that the transferring party will hold such Assets as trustee of the transferee party and all income and risk of loss of the transferred Assets until the completion of the Restructuring shall be for the account of the intended owner. Each of the parties hereto, at its own cost and expense, promptly shall execute such documents and other instruments and take such further actions as may be reasonably required or desirable to carry out the provisions hereof and to consummate the transactions contemplated hereby. SECTION 5.04 Cooperation. The parties shall cooperate with each other in all reasonable respects to ensure (a) that the Restructuring and the assumption of the Continuing Company Liabilities and the Assumed Liabilities are consummated in accordance with the terms hereof, (b) the retention by the Company of the Continuing Company Assets, (c) the transfer to Newco of all the Newco Assets and (d) the allocation of employee Liabilities and provision of employee benefits in accordance with the provisions of Article VI. ARTICLE VI EMPLOYEE MATTERS SECTION 6.01 Employment of Employees. Effective as of the Effective Time, Newco shall offer to each Employee (a) who participates in the Company's Termination Protection Program (the "Termination Protection Program") employment in a Qualifying Position (as defined in the Termination Protection Program) and (b) who does not participate in the Company's Termination Protection program substantially comparable employment to the employment of such Employee immediately prior to the Effective Time. For the avoidance of doubt, Newco hereby assumes as an Assumed Liability the Termination Protection Program and the Company's obligation thereunder. Nothing contained in this Section 6.01 shall confer on any Employee any right to continued employment after the Effective Time, and each Employee shall continue to be employed "at-will" subject to any requirements under applicable foreign Law or any applicable individual agreement to the contrary. SECTION 6.02 Liabilities Generally. Without limiting the generality of Section 4.02, effective as of the Effective Time, Newco shall assume and be solely responsible for all Liabilities (including any A-1-8 Liabilities imposed by Law) with respect to each employee benefit plan, as such term is defined in Section 3(3) of ERISA, each employment, severance or similar Contract, plan, arrangement or policy and each other plan or arrangement providing for compensation, bonuses, profit-sharing, stock option or other stock related rights or other forms of incentive or deferred compensation, health or medical benefits, disability benefits, workers' compensation, supplemental unemployment benefits, severance benefits or post-employment pension or welfare benefits, which is maintained, administered or contributed to by the Company or any Company Subsidiary and covers any Employee or former employee (and their beneficiaries) of, or independent contractor (and their beneficiaries) with respect to, the Company or any Company Subsidiary, other than the Company Stock Plans and the Termination Protection Program, (such plans and arrangements are referred to collectively herein as the "Transferred Benefit Plans"). SECTION 6.03 Preservation of Rights to Amend or Terminate Plans. Except as otherwise expressly provided in the Merger Agreement or this Restructuring Agreement, no provision of this Restructuring Agreement shall be construed as a limitation on the right of Newco to amend or terminate any Transferred Benefit Plan which right the Company or Newco, as applicable, would otherwise have under the terms of such Transferred Benefit Plan or otherwise, and no provision of this Restructuring Agreement shall be construed to create a right in any Employee or beneficiary of such Transferred Benefit Plan that such Employee or beneficiary would not otherwise have under the terms of the Transferred Benefit Plan itself. SECTION 6.04 Reimbursement; Indemnification. Newco acknowledges that the Company may incur costs and expenses (including contributions to plans and the payment of insurance, or other similar premiums) after the Effective Time pursuant to any of the Transferred Benefit Plans. Accordingly, Newco agrees to reimburse the Company, as promptly as practicable but in any event within 30 days of receipt from the Company of appropriate verification, for all such costs and expenses reasonably incurred after the Effective Time. If applicable foreign Law requires that the Company incur Liabilities in respect of Employees, notwithstanding the terms of this Restructuring Agreement, then Newco shall fully indemnify and hold harmless the Company to the extent of such Liabilities. All Liabilities retained, assumed or indemnified by Newco pursuant to this Article VI shall in each case be deemed to be Assumed Liabilities and shall be subject to the indemnification provisions set forth in Article II of the Post-Closing Covenants Agreement. SECTION 6.05 Actions By Newco. Any action required to be taken under this Article VI may be taken by one or more of the Newco Companies. SECTION 6.06 No Termination. To the extent permitted by applicable Law, the Company and Newco agree (a) that the transactions contemplated by this Restructuring Agreement, the other Transaction Agreements and the Commercial Agreements shall not constitute a termination of employment of any Employee that would entitle such Employee to receive severance or similar compensation and benefits and (b) to use their reasonable best efforts to amend, if necessary, any applicable Company Benefit Plans so to provide. If under applicable foreign Law, any Employee employed outside the U.S. is deemed to have incurred a termination of employment as a result of the transactions contemplated by this Restructuring Agreement which entitles such Employee to receive any payment or benefit under any non-U.S. Transferred Benefit Plan, governmental plan or arrangement or pursuant to any Law, including severance benefits, irrespective of such individual's continued employment by Newco, then notwithstanding anything in this Restructuring Agreement to the contrary, to the extent Legally Permitted (as defined below), appropriate adjustments shall be made to the treatment of such Employee during such continued employment, including not giving such Employee credit for prior service or treating such Employee as having been newly hired immediately after such deemed termination, for purposes of all applicable non-U.S. Transferred Benefit Plans. "Legally Permitted" means permitted under the Law of the country, the labor union, works council or collective bargaining agreement, including mandated waiting periods before which working conditions (including benefits) cannot be changed, and upon receiving required agreement from individuals or Transferred Benefit Plan trustees, foundation boards and members, and any other organizations having a recognized right to determine or affect benefits or funding of the Transferred Benefit Plan. A-1-9 ARTICLE VII CONDITIONS The obligations of the Company and Newco to consummate the Restructuring shall be subject to each of the Transaction Agreements and each of the Commercial Agreements having been executed and delivered by each of the parties thereto and being in full force and effect. This Article VII shall in no way restrict the ability of the Company or Newco to consummate the Restructuring or any portion thereof prior to the satisfaction of any condition thereto. ARTICLE VIII MISCELLANEOUS AND GENERAL SECTION 8.01 Modification or Amendment. The parties hereto may modify or amend this Restructuring Agreement only by written agreement executed and delivered by duly authorized officers of the respective parties; provided, however, that prior to the Effective Time, for so long as the Merger Agreement remains in effect, this Agreement shall not be amended or modified, and no provision hereof waived, without the prior written consent of Parent. SECTION 8.02 Termination. In the event the Merger Agreement is terminated pursuant to its terms prior to the Effective Time, this Restructuring Agreement shall automatically and simultaneously terminate and the Restructuring shall automatically and simultaneously be abandoned without the approval of Newco or the stockholders of the Company. In the event of such termination, no party shall have any Liability to any other party pursuant to this Restructuring Agreement. It is understood and agreed that the consummation of the Merger shall not constitute a termination of this Restructuring Agreement. The Confidentiality Agreement and the Letter Agreement shall survive termination of this Restructuring Agreement prior to the Effective Time. SECTION 8.03 Notices.

The words "hereof", "herein", "hereby" and "hereunder" and words of similar import when used in this Restructuring Agreement shall refer to this Restructuring Agreement as a whole and not to any particular provision of this Restructuring Agreement. The words "date hereof" shall refer to the date of this Restructuring Agreement. The term "or" is not exclusive. The word "extent" in the phrase "to the extent" shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply "if".

If any term or other provision of this Restructuring Agreement is invalid, illegal or incapable of being enforced by any applicable Law, or public policy, all other conditions and provisions of this Restructuring Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Restructuring Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible. SECTION 8.06 Counterparts. This Restructuring Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties. Each party need not sign the same counterpart. SECTION 8.07 Entire Agreement; Third-Party Beneficiaries. This Restructuring Agreement (a) taken together with the other Transaction Agreements, the Commercial Agreements, the Confidentiality Agreement and the Letter Agreement constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the Transactions and the transactions contemplated by the Commercial Agreements; provided, however, that as of and after the Effective Time, the Confidentiality Agreement shall have no further force and effect and shall be superseded by Section 3.07 of the Post-Closing Covenants Agreement and (b) nothing contained A-1-11 in this Restructuring Agreement is intended to confer upon any person other than the parties hereto and Parent, which shall be a third party beneficiary to this Restructuring Agreement, any benefit, right or remedy under or by reason of this Restructuring Agreement. SECTION 8.08 Certain Obligations. Whenever this Restructuring Agreement requires any of the subsidiaries of any party to take any action, this Restructuring Agreement will be deemed to include an undertaking on the part of such party to cause such subsidiary to take such action; provided, however, for the avoidance of doubt, at any time after the Effective Time, the Newco Companies shall not be considered to be subsidiaries of the Company. SECTION 8.09 Governing Law. This Restructuring Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. SECTION 8.10 Assignment. Neither this Restructuring Agreement nor any of the rights, interests or obligations under this Restructuring Agreement shall be assigned, in whole or in part, by operation of law or otherwise by any of the parties without the prior written consent of the other parties. Any purported assignment without such consent shall be void; provided, however, the parties acknowledge and agree that the conversion of Newco in accordance with Section 2.01 of this Restructuring Agreement and the continuation of Newco as a result thereof shall be deemed not to be an assignment and shall not require any consent of any party. Subject to the preceding sentences, this Restructuring Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns. SECTION 8.11 Enforcement; Consent to Service of Process. The parties agree that irreparable damage would occur in the event that any of the provisions of this Restructuring Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Restructuring Agreement and to enforce specifically the terms and provisions of this Restructuring Agreement in any New York state court or any Federal court located in the State of New York, this being in addition to any other remedy to which they are entitled at law or in equity. In addition, each of the parties hereto (a) consents to submit itself to the personal jurisdiction of any New York state court or any Federal court located in the State of New York in the event any dispute arises out of this Restructuring Agreement or any transaction contemplated in this Restructuring Agreement, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (c) agrees that it will not bring any action relating to this Restructuring Agreement or any transaction contemplated in this Restructuring Agreement in any court other than any New York state court or any Federal court located in the State of New York and (d) waives any right to trial by jury with respect to any action related to or arising out of this Restructuring Agreement or any transaction contemplated in this Restructuring Agreement. SECTION 8.12 Extension; Waiver. At any time prior to the Effective Time, the parties may (a) extend the time for the performance of any of the obligations or other acts of the other parties or (b) waive compliance with any of the agreements or conditions contained in this Restructuring Agreement. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Restructuring Agreement to assert any of its rights under this Restructuring Agreement or otherwise shall not constitute a waiver of such rights. A-1-12 IN WITNESS WHEREOF, this Restructuring Agreement has been duly executed and delivered by the duly authorized officers of the parties hereto as of the date first herein above written.

At the Effective Time, the separate corporate existence of Sub shall cease and the Company shall continue as the surviving corporation (the "Surviving Corporation"). The Merger and the other transactions contemplated by this Agreement and the other Transaction Agreements (as defined in Section 10.03) are referred to in this Agreement collectively as the "Transactions". SECTION 1.02. Closing. The closing of the Merger (the "Closing") shall take place at the offices of Cravath, Swaine & Moore LLP, 825 Eighth Avenue, New York, New York 10019 at 10:00 a.m. on the second business day following the satisfaction (or, to the extent permitted by Law (as defined in Section 4.05(a)), waiver by the applicable party or parties) of the conditions set forth in Article VIII (other than those conditions that by their terms cannot be satisfied until the time of the Closing but subject to the satisfaction (or, to the extent permitted by Law, waiver by the applicable party or parties) of such conditions); provided, however, that if all the conditions set forth in Article VIII shall not have been satisfied (or, to the extent permitted by Law, waived by the applicable party or parties) on such second business day, then the Closing shall take place on the first business day on which all such conditions shall have been satisfied (or, to the extent permitted by Law, waived by the applicable party or parties). The date on which the Closing occurs is referred to in this Agreement as the "Closing Date". SECTION 1.03. Effective Time. Prior to the Closing, the Company shall prepare, and, as soon as practicable on the Closing Date, the Company shall file with the Secretary of State of the State of Delaware, a certificate of merger (the "Certificate of Merger") executed in accordance with the relevant provisions of the DGCL. Parent or the Surviving Corporation shall make all other filings or recordings required under the DGCL as soon as practicable on or after the Closing Date. The Merger shall become effective at such time as the Certificate of Merger is duly filed with such Secretary of State, or at such other time as Parent and the Company shall agree and specify in the Certificate of Merger (the time at which the Merger becomes effective being the "Effective Time"). A-2-2 SECTION 1.04. Effects. The Merger shall have the effects set forth in Section 259 of the DGCL. SECTION 1.05. Certificate of Incorporation and By-laws. (a) The certificate of incorporation of the Company, as in effect immediately prior to the Effective Time, shall be amended at the Effective Time so that Article IV of such certificate of incorporation is amended to read in its entirety as follows: "The total number of shares of all classes of stock which the corporation shall have authority to issue is 100,000 shares of Common Stock, par value $0.001 per share", and, as so amended, such certificate of incorporation shall be the certificate of incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law. (b) The by-laws of Sub as in effect immediately prior to the Effective Time shall be the by-laws of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable Law. SECTION 1.06. Directors. The directors of Sub immediately prior to the Effective Time shall be the directors of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be. SECTION 1.07. Officers. The officers of Sub immediately prior to the Effective Time shall be the officers of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected or appointed and qualified, as the case may be. ARTICLE II EFFECT ON THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES SECTION 2.01. Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of any holder of any shares of Company Common Stock or any shares of capital stock of Sub: (a) Capital Stock of Sub. Each issued and outstanding share of capital stock of Sub shall be converted into and become one fully paid and nonassessable share of common stock, par value $0.001 per share, of the Surviving Corporation. (b) Cancelation of Treasury Stock and Parent-Owned Stock. Each share of Company Common Stock that is owned by the Company, Parent or Sub shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and no consideration shall be delivered or deliverable in exchange therefor. Each share of Company Common Stock that is owned by any subsidiary of the Company or Parent (other than Sub) shall automatically be converted into one fully paid and nonassessable share of common stock, par value $0.001 per share, of the Surviving Corporation. (c) Conversion of Company Common Stock. (i) Subject to Sections 2.01(b), 2.01(d) and 2.02(e), (A) a portion of each issued and outstanding share of Company Common Stock shall be converted into the right to receive, from the Company, one (the "Exchange Ratio") fully paid and nonassessable share of Newco Common Stock in exchange for such portion of each share of Company Common Stock that is equal in value to the Newco Common Stock received and (B) the remaining portion of each issued and outstanding share of Company Common Stock shall be converted into the right to receive, from Parent or Sub, an amount in cash equal to the Per Share Cash Merger Consideration. (ii) The shares of Newco Common Stock and the cash amount payable upon the conversion of shares of Company Common Stock pursuant to this Section 2.01(c) and cash in lieu of fractional shares of Newco Common Stock as contemplated by Section 2.02(e) are referred to collectively as the "Merger Consideration". As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares A-2-3 of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive Merger Consideration and any dividends or other distributions to which such holder is entitled pursuant to Section 2.02(c) upon surrender of such certificate in accordance with Section 2.02, without interest, and except for the right to receive payments to which such holder is entitled pursuant to Section 2.02(d), without interest. (d) Appraisal Rights. Notwithstanding anything in this Agreement to the contrary, shares ("Appraisal Shares") of Company Common Stock that are outstanding immediately prior to the Effective Time and that are held by any person who is entitled to demand and properly demands appraisal of such Shares pursuant to, and who complies in all respects with, Section 262 of the DGCL ("Section 262") shall not be converted into Merger Consideration as provided in Section 2.01(c), but rather the holders of Appraisal Shares shall be entitled to payment of the fair value of such Appraisal Shares in accordance with Section 262; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262, then the right of such holder to be paid the fair value of such holder's Appraisal Shares shall cease and such Appraisal Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive, Merger Consideration as provided in Section 2.01(c). The Company shall serve prompt notice to Parent of any demands received by the Company for appraisal of any shares of Company Common Stock, and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing. (e) Adjustments. If, during the period between the date of this Agreement and the Effective Time, the number of shares of Company Common Stock issued and outstanding changes (or there is established a record date for changing) as a result of a reclassification, recapitalization, stock split or combination, stock dividend, exchange or readjustment of the Company Common Stock, the Per Share Cash Merger Consideration and the Exchange Ratio shall be appropriately adjusted to reflect such reclassification, recapitalization, stock split or combination, stock dividend, exchange or readjustment. (f) Withholding Rights. Any of Parent, the Surviving Corporation, Newco or the Exchange Agent (as defined in Section 2.02(a)) shall be entitled to deduct and withhold from the consideration otherwise payable to any person pursuant to this Article II such amounts as it may be required to deduct and withhold with respect to the making of such payment in accordance with the Intended Treatment under any provision of Federal, state, local or foreign Tax law. To the extent that amounts so deducted or withheld and paid over to the appropriate Taxing Authority (as defined in Section 4.19(f)) are attributable to the portion of the consideration consisting of Newco Common Stock, then the Surviving Corporation, Newco or the Exchange Agent, as the case may be, will be treated as though the applicable payor withheld an appropriate amount of such consideration otherwise payable to a holder of Company Common Stock pursuant to this Agreement and then sold such consideration for an amount of cash equal to its fair market value at the time of such deemed sale and paid such cash proceeds to the appropriate Taxing Authority. All deducted or withheld amounts described in this Section 2.01(f) shall, for all purposes of this Agreement, be treated as having been paid to the applicable holder of the Company Common Stock, Company Convertible Debentures or Company Warrants (Company Convertible Debentures and Company Warrants, each as defined in Section 4.02(a)), as the case may be, in respect of which the Surviving Corporation, Parent or the Exchange Agent, as the case may be, made such deduction and withholding. SECTION 2.02. Exchange of Certificates. (a) Exchange Agent. (i) As of the Effective Time, the Company shall, or Newco shall, on behalf of the Company, deposit in trust with a bank or trust company as may be designated by Parent and reasonably acceptable to the Company (the "Exchange Agent"), for the benefit of the holders of shares of A-2-4 Company Common Stock outstanding immediately prior to the Effective Time, certificates representing the shares of Newco Common Stock (including all shares of Newco Common Stock owned by the Company at the Effective Time, whether as a result of the Restructuring or otherwise) issuable pursuant to Section 2.01 in exchange for shares of Company Common Stock converted pursuant to this Article II and (ii) Parent shall from time to time as needed deposit in trust with the Exchange Agent for the benefit of holders of shares of Company Common Stock, cash necessary to pay the cash amount of the Merger Consideration payable pursuant to Section 2.01 in exchange for the shares of Company Common Stock converted pursuant to this Article II (such shares of Newco Common Stock and cash, together with any dividends or other distributions with respect thereto, being hereinafter referred to as the "Exchange Fund"). The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Newco Common Stock and cash contemplated to be issued or paid pursuant to Section 2.01 out of the Exchange Fund. The Exchange Fund shall not be used for any other purpose. (b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates (the "Certificates") that immediately prior to the Effective Time represented outstanding shares of Company Common Stock, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent and the Company may reasonably specify prior to the Effective Time) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for Merger Consideration. Upon surrender of a Certificate for cancelation to the Exchange Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Newco Common Stock (together with cash in lieu of fractional shares) and the amount of cash that such holder has the right to receive pursuant to the provisions of this Article II, and the Certificate so surrendered shall forthwith be canceled. Until such time as a certificate representing Newco Common Stock is issued to or at the direction of the holder of a surrendered Certificate, such Newco Common Stock shall be deemed not outstanding and shall not be entitled to vote on any matter. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, a certificate representing the appropriate number of whole shares of Newco Common Stock (together with cash in lieu of fractional shares) and the appropriate amount of cash may be issued and paid to a person other than the person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other Taxes required by reason of the issuance of shares of Newco Common Stock and the payment of cash to a person other than the registered holder of such Certificate or establish to the reasonable satisfaction of Parent and Newco that such Taxes have been paid or are not applicable. No interest shall be paid or accrue on any cash payable upon surrender of any Certificate. (c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Newco Common Stock with a record date after the Effective Time shall be paid to the holder of any Certificate with respect to the shares of Newco Common Stock issuable upon surrender thereof, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.02(e), until the surrender of such Certificate in accordance with this Article II. Subject to applicable Law, following surrender of any such Certificate, there shall be paid to the holder of the certificate representing whole shares of Newco Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of Newco Common Stock to which such holder is entitled pursuant to Section 2.02(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Newco Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such whole shares of Newco Common Stock. A-2-5 (d) No Further Ownership Rights in Company Common Stock. The Merger Consideration paid upon the surrender for exchange of Certificates in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock, subject, however, to the Surviving Corporation's obligation to pay any dividends or make any other distributions with a record date prior to the Effective Time that may have been declared or made by the Company on such shares of Company Common Stock in accordance with the terms of this Agreement or prior to the date of this Agreement and that remain unpaid at the Effective Time, and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Certificates formerly representing shares of Company Common Stock are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article II. (e) No Fractional Shares. (i) No certificates or scrip representing fractional shares of Newco Common Stock shall be issued upon the conversion of Company Common Stock pursuant to Section 2.01, and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a holder of Newco Common Stock. For purposes of this Section 2.02(e), all fractional shares to which a single record holder would be entitled as a result of the conversion of all shares of Company Common Stock held by such holder as of the Effective Time under all Certificates shall be aggregated and calculations shall be rounded to three decimal places. (ii) As promptly as practicable following the Effective Time, the Exchange Agent shall determine the excess of (A) the number of shares of Newco Common Stock delivered to the Exchange Agent by the Company or Newco pursuant to Section 2.02(a) over (B) the aggregate number of whole shares of Newco Common Stock to be issued to holders of Company Common Stock pursuant to Section 2.02(b) (such excess being herein called the "Excess Shares"). As soon after the Effective Time as practicable, the Exchange Agent, as agent for the holders of Company Common Stock, shall sell the Excess Shares at then prevailing prices on the Nasdaq Stock Market ("Nasdaq"), if the shares of Newco Common Stock are quoted on Nasdaq, or otherwise on the national securities exchange on which the shares of Newco Common Stock are listed, all in the manner provided in Section 2.02(e)(iii). (iii) The sale of the Excess Shares by the Exchange Agent shall be executed on the Nasdaq or such national securities exchange, as the case may be, and shall be executed in round lots to the extent practicable. The proceeds from such sale or sales available for distribution to the holders of Company Common Stock shall be reduced by the compensation payable to the Exchange Agent and the expenses incurred by the Exchange Agent, in each case, in connection with such sale or sales of the Excess Shares, including all related commissions, Transfer Taxes (as defined in Section 7.08) and other out-of-pocket transaction costs. Until the net proceeds of such sale or sales have been distributed to the holders of Company Common Stock entitled thereto, the Exchange Agent shall hold such proceeds in trust for such holders of Company Common Stock (the "Newco Shares Trust"). The Exchange Agent shall determine the portion of the Newco Shares Trust to which each holder of a Certificate shall be entitled, if any, by multiplying the amount of the aggregate net proceeds comprising the Newco Shares Trust by a fraction, the numerator of which is the amount of the fractional share interest in a share of Newco Common Stock to which such holder is entitled under Section 2.01(c) (or would be entitled but for this Section 2.02(e)) and the denominator of which is the aggregate amount of fractional interests in a share of Newco Common Stock to which all holders of Company Common Stock are entitled. (iv) As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Company Common Stock in lieu of any fractional share interests in Newco Common Stock, the Exchange Agent shall in accordance with this Article II, make available such amounts, without interest, to the former holders of Company Common Stock entitled to receive such cash. A-2-6 (f) Termination of Exchange Fund and Newco Shares Trust. Any portion of the Exchange Fund that remains undistributed to the holders of the Certificates for 9 months after the Effective Time shall be delivered (i) in the case of shares of Newco Common Stock deposited in the Exchange Fund by the Company or Newco and cash deposited in the Exchange Fund by Newco, to Newco and (ii) in the case of cash deposited in the Exchange Fund by Parent or the Surviving Corporation, to Parent or the Surviving Corporation, as applicable, in each case upon demand, and any holders of the Certificates who have not theretofore complied with this Article II shall thereafter (x) look only to Newco for, and Newco shall remain liable for, payment of their claim for Newco Common Stock and any dividends or distributions with respect to Newco Common Stock and (y) look only to Parent for, and Parent shall remain liable for, payment of their claim for cash payable pursuant to Section 2.01(c)(i)(B), in each case in accordance with this Article II. Any portion of the Newco Shares Trust that remains undistributed to the holders of the Certificates for 9 months after the Effective Time shall be delivered to Newco, upon demand, and any holder of the Certificates who has not theretofore complied with this Article II shall thereafter look only to Newco for payment of its claim for such cash. (g) No Liability. None of Parent, Sub, the Company, Newco or the Exchange Agent shall be liable to any person in respect of any shares of Newco Common Stock or cash from the Exchange Fund or the Newco Shares Trust delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificate has not been surrendered prior to the date on which Merger Consideration in respect of such Certificate (or any dividends or other distributions with respect thereto) would otherwise escheat to or become the property of any Governmental Entity (as defined in Section 4.05(b))), any such shares or cash in respect of such Certificate shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation (with respect to any remaining cash payable pursuant to Section 2.01(c)(i)(B)) and the property of Newco (with respect to any remaining shares of Newco Common Stock and cash related thereto), free and clear of all claims or interest of any person previously entitled thereto. (h) Investment of Exchange Fund and the Newco Shares Trust. The Exchange Agent shall invest any cash included in the Exchange Fund and payable pursuant to Section 2.01(c)(i)(B) as directed by Parent, and any other cash included in the Exchange Fund as directed by Newco, in each case on a daily basis. Pending payment of such funds to the holders of Certificates for shares of Company Common Stock, such funds will be held and shall be invested by the Exchange Agent as directed in accordance with the previous sentence (so long as such directions do not impair the rights of holders of Company Common Stock) in the direct obligations of the United States, obligations for which the full faith and credit of the United States is pledged to provide for the payment of principal and interest or commercial paper rated of the highest quality by Moody's Investors Services, Inc. or Standard & Poor's Corporation. Parent or Newco, as applicable, will promptly replace any monies lost through any investment made in accordance with its instructions pursuant to this Section 2.02(h). If for any reason (including losses) the Exchange Fund or the Newco Shares Trust is inadequate to pay the amounts to which holders of the Company Common Stock shall be entitled under this Article II, Parent and the Surviving Corporation shall in any event be liable for payment thereof (with respect to cash payable pursuant to Section 2.01(c)(i)(B)) and Newco shall in any event be liable for payment thereof (with respect to shares of Newco Common Stock and cash related thereto). The Exchange Fund and the Newco Shares Trust shall not be used except as provided in this Agreement. Any interest and other income resulting from such investments shall be paid to Parent or the Surviving Corporation, as Parent directs (with respect to cash payable pursuant to Section 2.01(c)(i)(B)) and to Newco (with respect to any other cash). (i) Lost, Stolen or Destroyed Certificates. If any Certificate has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by Parent or Newco, the posting by such person of a bond in such reasonable amount as Parent or Newco may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration (and any dividends or other distributions with respect thereto) pursuant to this Article II. A-2-7 SECTION 2.03. Company Convertible Debentures. As of and after the Effective Time, from time to time and at any time upon the conversion of any Company Convertible Debentures by any holder thereof, (a) Newco shall deliver to such holder the number of shares of Newco Common Stock and cash in lieu of fractional shares of Newco Common Stock such holder would have been entitled to receive as if such holder had converted the Company Convertible Debentures into shares of Company Common Stock immediately prior to the Effective Time and (b) Parent shall, or shall cause the Company to, deliver to such holder the amount of cash such holder would have been entitled to receive as if such holder had converted the Company Convertible Debentures into shares of Company Common Stock immediately prior to the Effective Time. SECTION 2.04. Company Warrants.

Parent shall furnish all information concerning Parent, the Transactions, the Transaction Agreements and the Commercial Agreements and shall provide all other assistance and cooperation as may be reasonably requested by the Company in connection with the preparation, filing and distribution of the Proxy Statement and the Newco Form S-4 and any other action described in this Section 7.01(a). The parties shall notify each other promptly of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to the Proxy Statement, the Newco Form S-4 or the Newco Form 8-A or for additional information and shall supply each other with copies of all correspondence between it or any of its Representatives, on the one hand, and the SEC or its staff on the other hand, with respect to the Proxy Statement, the Newco Form S-4, the Newco Form 8-A, the Merger, the other Transactions, the Transaction Agreements or the Commercial Agreements.

The Company shall, through the Company Board, recommend to its stockholders that they give the Company Stockholder Approval, except to the extent that the Company Board shall have withdrawn or modified its approval or recommendation of this Agreement, the Restructuring or the Merger as permitted by Section 6.02(b). Without limiting the generality of the foregoing, the Company agrees that its obligations pursuant to the first sentence of this Section 7.01(b) shall not be affected by (i) the commencement, public proposal, public disclosure or communication to the Company of any Company Takeover Proposal or (ii) the withdrawal or modification by the Company Board of its approval or recommendation of this Agreement, the Restructuring or the Merger. SECTION 7.02. Access to Information; Confidentiality.

Subject to the next two sentences of this Section 7.02, all information exchanged pursuant to this Section 7.02 shall be subject to the confidentiality agreement dated October 8, 2001, between the Company and affiliates of Parent (the "Confidentiality Agreement"), and the letter agreement dated November 6, 2002, between the Company and R Diagnostics (the "Letter Agreement"). As of and after the Effective Time, the Confidentiality Agreement shall have no further force and effect and shall be superseded by Section 3.07 of the Post-Closing Covenants Agreement.

Upon the terms and subject to the conditions set forth in this Agreement, each of the parties shall use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other Transactions, including (a) the taking of all acts necessary to cause the conditions to Closing to be satisfied as promptly as practicable, (b) the obtaining of all necessary actions or nonactions, waivers and Consents from Governmental Entities and the making of all necessary registrations and filings (including filings with Governmental Entities, if any) and the taking of all reasonable steps as may be necessary to obtain a Consent or waiver from, or to avoid an action or proceeding by, any Governmental Entity, (c) the obtaining of all necessary Consents or waivers from third parties; provided, however, that the parties shall not be required to pay or commit to pay any amount to (or incur any obligation in favor of) any person from whom any such Consent or waiver may be required (other than nominal filing or application fees), (d) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of any of the Transactions, including seeking to have any stay, order or injunction entered by any court or other Governmental Entity preventing consummation of any of the Transactions vacated or reversed and (e) the execution and delivery of any additional instruments necessary to consummate the Transactions and to fully carry out the purposes of this Agreement and the other Transaction Agreements. In connection with and without limiting the foregoing, (i) the Company and the Company Board shall (A) take all action necessary to ensure that no state takeover statute or similar statute or regulation is or becomes applicable to any Transaction or this Agreement or any other Transaction Agreement and (B) if any state takeover statute or similar statute or regulation becomes applicable to any Transaction or this Agreement or any other Transaction Agreement, take all action necessary to ensure that the Merger and the other Transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Merger and the other Transactions and (ii) Parent, on behalf of itself and its subsidiaries and affiliates, is hereby deemed to have granted any consent with respect to, and waived compliance with any requirements of, any term or provision of any Contract or arrangement in effect as of the date of this Agreement, between and among Parent or any of its subsidiaries or affiliates, on the one hand, and the Company or any Company Subsidiaries or affiliates, on the other hand, to the extent necessary in order to consummate the Transactions without resulting in a breach, default or other violation of any such Contract or arrangement. Notwithstanding the foregoing, the Company and its Representatives shall not be prohibited under this Section 7.03 from taking any action permitted by Section 6.02. A-2-26 SECTION 7.04. Stock Options. (a) As soon as reasonably practicable following the date of this Agreement (or, in the case of any Company Stock Plan adopted after the date of this Agreement and prior to the Effective Time, as soon as reasonably practicable following the date of such Plan's adoption), the Company Board (or, if appropriate, any committee administering the Company Stock Plans) shall adopt such resolutions or take such other actions as may be required in order that each outstanding Company Stock Option, whether vested or unvested, shall be canceled upon the occurrence of the Effective Time, and that the holder of such Company Stock Option shall become entitled, within five business days following the Effective Time, to receive (i) a cash payment from Parent, in an amount equal to the product of (A) the excess of the Per Share Cash Merger Consideration over the exercise price of such Company Stock Option multiplied by (B) the number of shares of Company Common Stock for which such Company Stock Option shall not theretofore have been exercised (the "Option Shares") and (ii) a number of shares of Newco Common Stock from the Company equal to the product of (A) the Exchange Ratio multiplied by (B) the number of Option Shares. To the extent that the foregoing provisions would otherwise require the Company to provide to the holder of a Company Stock Option a fractional share of Newco Common Stock, the Exchange Agent will instead pay cash in lieu of such fractional share based on the value of a share of Newco Common Stock determined in accordance with Section 2.02(e). All payments and distributions pursuant to this Section shall be subject to all appropriate withholding. (b) Prior to the Effective Time, the Company Board shall adopt resolutions terminating the Company Stock Plans, and deleting provisions in any other Company Benefit Plan providing for the issuance, transfer or grant of any capital stock of the Company or any interest in respect of any capital stock of the Company, as of the Effective Time.

SECTION 2.03. Procedures Relating to Indemnification. (a) In order for an Indemnitee to be entitled to any indemnification provided for under this Agreement in respect of, arising out of or involving a claim made by any person who is not an Indemnitee against such Indemnitee (a "Third Party Claim"), such Indemnitee must notify the party who may become obligated to provide indemnification hereunder (the "Indemnifying Party") in writing, and in reasonable detail, of the Third Party Claim reasonably promptly, and in any event within 10 Business Days after receipt by such Indemnitee of written notice of the Third Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party shall have been actually and materially prejudiced as a result of such failure; provided further, however, that with respect to any Third Party Claim for which Newco is the Indemnifying Party, such Indemnifying Party shall be deemed A-3-4 to have received notice with respect to such Third Party Claim by or against the Company or any of its subsidiaries (other than the Newco Companies) for which the Company or any of its subsidiaries (other than the Newco Companies) received notice prior to the Effective Time. After any required notification (if applicable), the Indemnitee shall deliver to the Indemnifying Party, promptly after the Indemnitee's receipt thereof, copies of all notices and documents (including court papers) received by the Indemnitee relating to the Third Party Claim. (b) If a Third Party Claim is made against an Indemnitee, the Indemnifying Party will be entitled to participate in the defense thereof and, if it so chooses, to assume the defense thereof (at the expense of the Indemnifying Party) with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnitee. Should the Indemnifying Party so elect to assume the defense of a Third Party Claim, the Indemnifying Party will not be liable to the Indemnitee for any legal expenses subsequently incurred by the Indemnitee in connection with the defense thereof. If the Indemnifying Party assumes such defense, the Indemnitee shall have the right to participate, at its own expense, in the defense thereof solely to assert any additional defenses and to employ counsel, at its own expense, except as set forth below, separate from the counsel employed by the Indemnifying Party, it being understood that the Indemnifying Party shall control such defense. The Indemnifying Party shall be liable for the reasonable fees and expenses of counsel employed by the Indemnitee for any period during which the Indemnifying Party has not assumed the defense thereof (other than during any period in which the Indemnitee shall have failed to give notice of the Third Party Claim as provided above). Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to assume the defense of any Third Party Claim (and shall not be liable for the fees and expenses of counsel incurred by the Indemnitee in defending such Third Party Claim, except for the reasonable fees and expenses of counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnitee) if the Third Party Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the Indemnitee which the Indemnitee reasonably determines, after conferring with its counsel, cannot be separated from any related claim for money damages. If such equitable or other relief portion of the Third Party Claim can be so separated from that for money damages, the Indemnifying Party shall be entitled to assume the defense of the portion relating to money damages. The indemnification required by Section 2.01 or 2.02, as the case may be, shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or the Indemnifiable Loss is incurred. If the Indemnifying Party chooses to defend or prosecute a Third Party Claim (i) all the parties hereto reasonably necessary or appropriate for such defense or prosecution shall cooperate in the defense or prosecution thereof, which cooperation shall include the retention in accordance with this Agreement and (upon the Indemnifying Party's request) the provision to the Indemnifying Party of records and information which are reasonably relevant to such Third Party Claim, (ii) the Indemnifying Party shall keep the Indemnitee reasonably informed of all significant developments in connection with the defense or prosecution of such Third Party Claim and (iii) the Indemnitee will agree to any settlement, compromise or discharge of such Third Party Claim which the Indemnifying Party may recommend (after representing to the Indemnitee that such settlement is reasonably likely to be acceptable to the parties to the Third Party Claim) and which by its terms obligates the Indemnifying Party to pay the full amount of liability in connection with such Third Party Claim; provided, however, that, without the Indemnitee's consent (which consent shall not be unreasonably withheld, conditioned or delayed), the Indemnifying Party shall not consent to entry of any Judgment or enter into any settlement (x) that provides for injunctive or other nonmonetary relief affecting the Indemnitee or its properties or (y) that does not include as an unconditional term thereof the giving by each claimant or plaintiff to such Indemnitee of a release from all liability with respect to such claim; provided further, however, that if the Indemnitee does not consent to any settlement recommended by the Indemnifying Party (after representing to the Indemnitee that such settlement is reasonably likely to be acceptable to the parties to the Third Party Claim) then the Indemnifying Party (1) shall not in any event be obligated to indemnify the Indemnitee, or otherwise be responsible, for any amount in excess of the amount of the settlement so recommended by the Indemnifying Party and (2) shall be entitled to reimbursement of the fees and expenses of counsel incurred by the Indemnifying Party after the date on which the recommendation was made to the Indemnitee in the event the final and unappealable Judgment A-3-5 in such Third Party Claim exceeds the amount of the settlement so recommended. If the Indemnifying Party shall have assumed the defense of a Third Party Claim, the Indemnitee shall not admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the Indemnifying Party's prior written consent. If the Indemnifying Party does not or is not entitled to assume the defense of a Third Party Claim, the Indemnitee may defend the same in such manner as it may deem appropriate; provided, however, that the Indemnitee shall not admit any liability with respect to, or settle, compromise or discharge such Third-Party Claim without the Indemnifying Party's prior written consent. (c) In order for an Indemnitee to be entitled to any indemnification provided for under this Agreement in respect of a claim that does not involve a Third Party Claim, the Indemnitee shall deliver notice of such claim (in reasonably sufficient detail to enable the Indemnifying Party to evaluate such claim) with reasonable promptness to the Indemnifying Party. The failure by any Indemnitee to give such notification shall not affect the indemnification provided hereunder except to the extent that the Indemnifying Party shall have been actually and materially prejudiced as a result of such failure. If the Indemnifying Party does not notify the Indemnitee within 20 Business Days following its receipt of such notice that the Indemnifying Party disputes its liability with respect to such claim under Section 2.01 or 2.02, as the case may be, the claim shall be conclusively deemed a liability of the Indemnifying Party under Section 2.01 or 2.02, as the case may be, and the Indemnifying Party shall pay the amount of such liability to the Indemnitee on demand or, in the case of any notice in which the amount of the claim (or any portion thereof) is estimated, on such later date when the amount of such claim (or such portion thereof) becomes finally determined. If the Indemnifying Party has timely disputed its liability with respect to such claim, as provided above, the Indemnifying Party and the Indemnitee shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in an appropriate court of competent jurisdiction. (d) Notwithstanding any other provision of this Agreement, Newco acknowledges and agrees that Newco shall (solely at its own cost and expense) assume and continue the defense of the Newco Litigation and use its reasonable best efforts to defend any Parent Indemnitee and to cause any Parent Indemnitee to be dismissed with prejudice as a party to any Newco Litigation. SECTION 2.04. Certain Limitations. (a) The amount of any Indemnifiable Losses or other liability for which indemnification is provided under this Agreement shall be net of any amounts actually recovered by the Indemnitee from third parties (including amounts actually recovered under insurance policies) with respect to such Indemnifiable Losses. The Indemnitee shall use its reasonable best efforts to seek to obtain recovery in respect of any Indemnifiable Loss or such other liability under any available insurance policy. (b) No Indemnitee shall be entitled to indemnification provided for under this Agreement if the facts, events or other circumstances giving rise to the indemnification claim arose from or are related to (i) any breach of the representations, warranties, covenants or agreements of such Indemnitee or its affiliates in this Agreement or in any other Transaction Agreement (it being understood that the representations, warranties, covenants and agreements of the Company in the Merger Agreement shall for the sole purpose of this Section 2.04(b) be deemed to have been given by Newco) or (ii) actions, omissions, inactions or disclosures taken or made by the Indemnitee or its affiliates. (c) All indemnification payments under this Agreement shall be reduced to take account of the present value of any net Tax benefit (including any current or future deductions, any reduction of income or gain upon a sale, disposition, conveyance, license or other similar transaction as a result of increased Tax basis, any Tax refunds received, any use of a credit of Taxes and any increase in the amount of losses, reliefs, allowances or other similar Tax attributes) realized by the Indemnitee in connection with or otherwise arising (directly or indirectly) from the incurrence of any Indemnifiable Loss. Upon the written request of the Indemnifying Party, the Indemnitee shall provide the amount of the Tax benefit realized by the Indemnitee in connection with or otherwise arising (directly or indirectly) from the incurrence of any Indemnifiable Loss together with reasonable detail with respect to such calculation. In computing the amount of any such Tax benefit, the Indemnitee shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt of any indemnification A-3-6 payment hereunder or the incurrence or payment of any Indemnifiable Loss. The Indemnitee shall cooperate fully with all requests from the Indemnifying Party in connection with determining the present value of such net Tax benefit. (d) The amount of all indemnification obligations under this Agreement shall be calculated on an after-tax basis (without taking into account any net operating loss or other similar tax credit or item available to offset such amount). Any payments made to one party by another party pursuant to this Agreement shall be treated for all Tax purposes as nontaxable payments (dividends or capital contributions, as the case may be) made between Newco and the Company immediately prior to the Merger, unless, and then only to the extent, otherwise required by a Final Determination (as defined in the Tax Allocation Agreement). SECTION 2.05. Exclusivity of Tax Allocation Agreement. Except for Sections 2.04(c), 2.04(d) and 3.02 of this Agreement, and Sections 2.01(f), 4.19 and 7.08 of the Merger Agreement, the Tax Allocation Agreement shall be the exclusive agreement among the parties with respect to all Tax matters, including indemnification and any procedures in connection therewith. SECTION 2.06. Exclusivity of Remedies. From and after the Effective Time, the remedies provided for in this Article II shall, as between the parties, be the exclusive monetary remedies of the parties to this Agreement with respect to the Transaction Agreements, except if the indemnification for the Indemnifiable Losses provided for in this Article II is unavailable to any Indemnitee for any reason, the Indemnifying Party shall contribute to the amount paid or payable by such Indemnitee as a result of any Indemnifiable Losses in such proportion as is appropriate to reflect any relevant equitable considerations. Each party hereto agrees that the previous sentence shall not limit or otherwise affect any non-monetary right or remedy which any party to this Agreement may have under the Transaction Agreements or otherwise limit or affect any such party's right to seek equitable relief, including specific performance. For the avoidance of doubt, each party hereto agrees that this Article II shall not confer any (a) additional remedy on any person for any breach of any representation, warranty or covenant contained in any Commercial Agreement, except as provided in 2.01(f), and (b) remedy on any person for any breach of any covenant or agreement set forth in any Transaction Agreement that does not survive the Effective Time. ARTICLE III OTHER AGREEMENTS SECTION 3.01. Insurance. From the Effective Time until the expiration of such policies according to their terms, the Company shall use its reasonable best efforts to maintain in effect the insurance policies maintained by the Company immediately prior to the Effective Time (other than directors' and officers' liability insurance policies, which are the subject of Section 3.08(b)) for which premiums have been paid in full prior to the Effective Time and shall not take any action to surrender, terminate or otherwise limit the coverage thereof; provided, however, that in maintaining such policies, the Company shall not be required to make any expenditures or incur any Liabilities with respect to the maintenance of such policies (other than any expenditures in connection with administering or making claims under such policies, which expenditures shall be reimbursed by Newco). In the event that any Newco Asset suffers any damage, destruction or other casualty loss, the Company shall surrender to Newco (a) all insurance proceeds received with respect to such damage, destruction or casualty loss and (b) all rights of the Company with respect to any causes of action in connection with such damage, destruction or casualty loss. The Company shall make available to the Newco Companies the benefit of any workers' compensation, general liability, product liability, automobile liability, umbrella (excess) liability or crime or other insurance policy covering or relating to the Newco Business, the Newco Assets or the Assumed Liabilities. The Company shall promptly pay to Newco all insurance proceeds relating to the Newco Business, the Newco Assets or the Assumed Liabilities received by the Company under any insurance policy. Nothing in this Section 3.01 shall (i) reduce, limit or otherwise affect the right of the Company to seek or obtain insurance proceeds with respect to any damage, destruction or casualty loss to or of a Continuing Company Asset, nor shall anything in this Section 3.01 reduce, limit or otherwise affect any of A-3-7 the rights of Newco or any other Newco Indemnitee set forth in Article II or (ii) require the Company to obtain any additional insurance with respect to any Newco Asset. SECTION 3.02. Characterization of Payments. The payments made pursuant to this Agreement shall be treated as occurring immediately before the Effective Time, and none of the Newco Companies, the Company and its subsidiaries and Parent and its subsidiaries or any affiliate of any of the foregoing shall take any position inconsistent with such treatment before any Taxing Authority (as defined in the Tax Allocation Agreement), except to the extent that a Final Determination with respect to the recipient party causes any such payment to not be so treated. SECTION 3.03. Agreement Not to Solicit Employees. (a) Parent understands that Newco shall be entitled to protect and preserve the going concern value of the Newco Business to the extent permitted by Law and that Newco would not have entered into this Agreement, the Restructuring Agreement, the Merger Agreement or the other Transaction Agreements to which it is a party absent the provisions of this Section 3.03; provided, however, that this Section 3.03 shall not inure to the benefit of any person (or such person's affiliates other than Newco and its subsidiaries as of immediately prior to the date of such sale, conveyance, transfer, lease or acquisition) (i) to whom Newco sells, conveys, transfers or leases, in one transaction or a series of related transactions, directly or indirectly, all or substantially all of its assets or (ii) who acquires, in one transaction or a series of related transactions, directly or indirectly, more than a majority of the outstanding shares of Newco Common Stock whether by stock purchase, merger, share exchange or otherwise. (b) Parent agrees that for a period of two years from and after the Effective Time, it shall not, and shall not permit its subsidiaries to, directly or indirectly, solicit for employment any individual employed by any Newco Company or any of their respective divisions. Notwithstanding the foregoing, it shall not constitute a breach of the foregoing sentence if Parent or its subsidiaries make solicitations for employment by general advertisements in periodicals of broad distribution or other advertisement media of similar nature that are not specifically directed at Employees. SECTION 3.04. Successors. (a) Newco shall not consolidate with or merge with or into, or sell, convey, transfer or lease, in one transaction or a series of related transactions, all or substantially all of its assets to, any person, unless the resulting, surviving or transferee person (the "Newco Successor Company") shall expressly assume in writing all the obligations of Newco under this Agreement. Except as otherwise provided in Section 3.03(a), such Newco Successor Company shall be the successor to Newco and shall succeed to, and be substituted for, Newco under this Agreement, but in the case of a sale, conveyance, transfer or lease of less than substantially all of its assets, Newco shall not be released from its obligations hereunder. (b) Parent shall not consolidate with or merge with or into, or sell, convey, transfer or lease, in one transaction or a series of related transactions, all or substantially all of its assets to, any person, unless the resulting, surviving or transferee person (the "Parent Successor Company") shall expressly assume in writing all the obligations of Parent under this Agreement. Such Parent Successor Company shall be the successor to Parent and shall succeed to, and be substituted for, Parent under this Agreement, but in the case of a sale, conveyance, transfer or lease of less than substantially all of its assets, Parent shall not be released from its obligations hereunder. SECTION 3.05. Third Party Rights; Notices. (a) In the event that after the Effective Time any of the Newco Companies holds any right to indemnification other than a right to indemnification under this Agreement or any other contractual or other right (collectively, a "Newco Recourse Right") with respect to any Continuing Company Liability or any Assumed Liability for which the Company is held responsible, then (i) to the extent possible such Newco Recourse Right shall be deemed to be held as a shared right of the applicable Newco Companies and the Company to the extent necessary to protect the Company against such Continuing Company Liability or such Assumed Liability and (ii) to the extent not so possible, Newco shall, or shall cause the applicable Newco Company to, assert or otherwise make available to the Company the full benefit of such Newco Recourse Right by making a claim on behalf of the Company or taking other steps reasonably requested by the Company. A-3-8 (b) In the event that after the Effective Time the Company holds any right to indemnification or any other contractual or other right (collectively, a "Company Recourse Right") with respect to any Assumed Liability or any Continuing Company Liability for which any of the Newco Companies are held responsible, then (i) to the extent possible such Company Recourse Right shall be deemed to be held as a shared right of the Company and the applicable Newco Companies to the extent necessary to protect the Newco Companies against such Assumed Liability or such Continuing Company Liability and (ii) to the extent not so possible, the Company shall assert or otherwise make available to the Newco Companies the full benefit of such Company Recourse Right by making a claim on behalf of the Newco Companies or taking other steps reasonably requested by the Newco Companies. (c) The Company hereby agrees to provide prompt written notice to Newco of any notice or other written communication received by the Company with respect to any Retained Contract and a copy of such notice or other written communication. SECTION 3.06. Retention of Records. Except as provided in any of the Transaction Agreements and except for any records related to Taxes (as defined in the Tax Allocation Agreement) which are the subject of, and governed by, the Tax Allocation Agreement, if any Company Records (as defined in the Restructuring Agreement) are retained by the Company or a Newco Company, the Company shall, and Newco shall, and Newco shall cause the other Newco Companies to, retain all such Company Records in the Company's or Newco Companies' possession or under their respective control until such Company Records are at least six years old (or for such longer period as may be required by Law) except that if, prior to the expiration of such period, the Company or any Newco Company wishes to destroy or dispose of any such Company Records that are at least three years old, then prior to destroying or disposing of any of such Company Records, (a) the Company or Newco, as applicable, shall provide no less than 60 days' prior written notice to the other person, specifying the Company Records proposed to be destroyed or disposed of, and (b) if, prior to the scheduled date of such destruction or disposal, the other person requests in writing that any of the Company Records proposed to be destroyed or disposed of be delivered to such other person, the Company or Newco, as applicable, promptly shall arrange for the delivery of the requested Company Records to a location specified by, and at the expense of, the requesting person. SECTION 3.07. Confidentiality; Preservation of Privilege; Access. (a) (i) Parent shall keep, and shall cause its affiliates and Representatives to keep, the Newco Information strictly confidential and will disclose such Newco Information only to such of its affiliates and Representatives who need to know such Newco Information and who agree to be bound by this Section 3.07 and agree not to disclose such Newco Information to any other person. Without the prior written consent of Newco, Parent shall not, and Parent shall cause each other receiving person and their respective Representatives not to, disclose the Newco Information to any person except as may be required by Law or judicial process and in accordance with this Section 3.07. (ii) Newco shall keep, and shall cause its affiliates and Representatives to keep, the Parent Information strictly confidential and will disclose such Parent Information only to such of its affiliates and Representatives who need to know such Parent Information and who agree to be bound by this Section 3.07 and agree not to disclose such Parent Information to any other person. Without the prior written consent of Parent, Parent shall not, and shall cause each other receiving person and their respective Representatives not to disclose the Parent Information to any person except as may be required by Law or judicial process and in accordance with this Section 3.07. (b) (i) In the event that any receiving person or any of its Representatives receives a request or is required by Law or judicial process to disclose to a court or other tribunal all or any part of the Newco Information, such receiving party or its Representatives shall promptly notify Newco of the request in writing, and consult with and assist Newco in seeking a protective order or request for other appropriate remedy. In the event that such protective order or other remedy is not obtained or Newco waives compliance with the terms of this Section 3.07, such receiving party or its Representatives, as applicable, shall disclose only that portion of the Newco Information or facts which it determines in good faith, after consultation with outside counsel, is legally required to be disclosed, and will exercise its reasonable best efforts to assure that confidential treatment will be accorded such Newco Information or facts by the persons or entities receiving the same. Newco will be given an opportunity to review the Newco A-3-9 Information or facts prior to disclosure. (ii) In the event that any receiving person or any of its Representatives receives a request or is required by Law or judicial process to disclose to a court or other tribunal all or any part of the Parent Information, such receiving party or its Representatives shall promptly notify Parent of the request in writing, and consult with and assist Parent in seeking a protective order or request for other appropriate remedy.

Parent will be given an opportunity to review the Parent Information or facts prior to disclosure. (c) Each party to this Agreement shall, promptly (and in any event within 10 Business Days of such receipt) upon its receipt or the receipt by any of its affiliates of a request or requirement (by oral questions, interrogatories, requests for documents, Parent Information or Newco Information, as applicable, subpoenas, civil investigative demands or other similar processes) reasonably regarded as calling for the inspection or production of any documents or other Parent Information or Newco Information, as applicable, which relates to the business or operations of any other party to this Agreement (a "Request"), notify the party to this Agreement whose documents, Parent Information or Newco Information, as applicable, is the subject of such Request. The preceding sentence shall apply regardless of whether the person delivering the Request is a party in the claim, suit, action, arbitration, inquiry, investigation or other proceeding of any nature (whether criminal, civil, legislative, administrative, regulatory, prosecutorial or otherwise) by or before any arbitrator or Governmental Entity or similar person or body (each, an "Action"), to which the Request relates. In addition to complying with the applicable provisions of Section 3.07(b), each party shall use reasonable best efforts to assert and maintain, or cause its affiliates to assert and maintain, any applicable claim to privilege, immunity, confidentiality or protection in order to protect such documents and other Parent Information or Newco Information, as applicable, from disclosure, and shall use reasonable best efforts to seek to condition any disclosure which may be required on such protective terms as it may reasonably determine to be appropriate. Following the receipt of the notice described in the first sentence of this Section 3.07(c), no party may waive an applicable privilege without the prior written consent of the affected party to this Agreement (or any affected affiliate or affiliates of any such party) except, in the opinion of such party's counsel, as required by Law. (d) From and after the Effective Time, Newco shall, and shall cause each Newco Company to, afford to Parent, and to Parent's Representatives, reasonable access during normal business hours to documents within the possession or control of any Newco Company that were Assets of the Company transferred to Newco in the Restructuring (other than any Asset that constitutes a Company Record), to the extent such access is reasonably required for the purposes of defending any Action commenced or threatened in writing against the Company (other than any Action which arose or resulted from or is related to any breach of any Transaction Agreement or in which the Company and Newco's interests are adverse) directly relating to the business, Assets (other than Intellectual Property Rights or any Asset related thereto) or Liabilities of the Company as they existed immediately prior to giving effect to the Restructuring; provided, however, that such access will not unreasonably interfere with the normal operations of any Newco Company and the reasonable out-of-pocket expenses of any Newco Company incurred in connection therewith will be paid by Parent; provided further, however, that any Newco Company may withhold (i) any document that (A) the disclosure of which would violate any Contract with a third party or any applicable Law or Judgment or would result in the waiver of any legal privilege or work-product protection (provided that such Newco Company shall have used its reasonable best efforts to obtain a Consent or waiver from such third party or to establish a joint-defense privilege to the extent it is reasonably available, as applicable; provided, however, that such Newco Company shall not be required to pay or commit to pay any amount to (or incur any obligation in favor of) any person from whom such Consent or waiver may be required) or (B) otherwise relates to any Action between the Newco and any of its affiliates, on the one hand, and the Company and any of its affiliates, on the other hand, or (ii) such documents or portions of documents that Newco determines in good faith, after consultation with outside A-3-10 counsel, should not be disclosed in order to ensure compliance with antitrust or other similar Law or Judgment. For the avoidance of doubt, all documents provided to Parent, or Parent's Representatives pursuant to this Section 3.07(e) shall be subject to Parent's obligations with respect to Newco Information contained in paragraphs (a) and (b) of Section 3.07. (e) Each of the parties to this Agreement hereby agrees that (i) nothing in this Section 3.07 shall override any confidentiality obligation owed by it or its affiliates pursuant to any Commercial Agreement and (ii) in the event of a conflict between the confidentiality provisions set forth in any Commercial Agreement, on the one hand, and this Agreement, on the other hand, the provisions set forth in the applicable Commercial Agreement shall govern. SECTION 3.08. Indemnification; Certain Claims. (a) To the fullest extent permitted by Law, Parent shall cause the Company to honor all its obligations to indemnify (including any obligations to advance funds for expenses) the current or former directors or officers of the Company for acts or omissions by such directors or officers occurring prior to the Effective Time to the fullest extent that such obligations of the Company exist on the date of this Agreement pursuant to the Company Charter, the Company By-laws or individual indemnity agreements and such obligations shall survive the Merger and shall continue in full force and effect in accordance with their respective terms until the expiration of the applicable statute of limitations with respect to any claims against such directors or officers arising out of such acts or omissions. (b) From the Effective Time until the sixth anniversary of the Effective Time, Parent shall cause to be maintained in effect the current policies of directors' and officers' liability insurance maintained by the Company (provided that Parent may cause to be substituted therefor policies with reputable and financially sound carriers of at least the same coverage and amounts containing terms and conditions which are no less advantageous) with respect to claims arising from or related to facts or events which occurred at or before the Effective Time; provided that in satisfying its obligation under this Section 3.08(b), Parent shall not be obligated to pay premiums in excess of 250% of the amount per annum required to be paid by the Company in the twelve months ending December 12, 2003, which amount is set forth in clause (x) of Section 6.01 (introductory paragraph) of the Company Disclosure Letter; and provided, further, that if the annual premiums of such insurance exceed such amount, Parent shall nevertheless obtain such insurance; provided that Newco shall pay the Company the amount of any premiums in excess of 250% of the amount per annum required to be paid by the Company in the twelve months ending December 12, 2003. (c) Parent shall not permit the Company to amend or repeal any provision of the Company Charter or Company By-laws after the Effective Time if such action would adversely affect the rights of individuals who on or prior to the Effective Time were entitled to advances, indemnification or exculpation thereunder for actions or omissions by such individuals prior to the Effective Time. The individuals referred to in the preceding sentence shall include any individuals who served as of the Effective Time as directors or officers of any subsidiary of the Company at the Company's request, it being acknowledged by the parties hereto that each director or officer of the Company who is currently serving as a director or officer of a subsidiary of the Company is doing so at such request of the Company. (d) In the event the Company or any successor to the Company (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all its properties and assets to any person, then, and in each case, proper provision shall be made so that the successors to the Company or the successors of any successor to the Company, as the case may be, honor the obligations of the Company set forth in this Section 3.08. For the avoidance of doubt, this Section 3.08(d) shall similarly apply to successive consolidations, mergers and transfers. (e) Following the Effective Time, Parent shall not, and Parent shall not permit the Company or any other affiliate of Parent or encourage any other person to, assert any rights or pursue any Action, whether directly or on a derivative basis, against (i) the Company or any of its affiliates or Newco or any of its affiliates or (ii) any of the current or former directors, officers, members of the board of managers, members, managers, consultants, advisors, attorneys, trustees, agents or individuals in the employment of A-3-11 the Company or any of its affiliates or of Newco or any of its affiliates (in each case, solely in their capacities as such), in each case for acts or omissions occurring prior to the Effective Time, whether known or unknown, and Parent shall not, and Parent shall not permit the Company or any other affiliate of Parent to, cooperate with any person in the assertion of any such rights or pursuing any such Action except (x) as required by subpoena or other judicial or legal process or (y) as required by any inquiry by a Governmental Entity, but in each case only to the extent such inquiry or requirement to cooperate has not arisen as a result of a breach of this Section 3.08(e); provided, however, that this Section 3.08(e) shall not (A) affect any person's right to enforce any Transaction Agreement, any Commercial Agreement, any Newco I/R Agreement or any agreement entered into between the Company, Newco or any of their respective affiliates, on the one hand, and any of the R Parties or any of their respective affiliates, on the other hand, after the date of this Agreement but prior to the Effective Time or any provision herein or therein in accordance with its terms, (B) apply to any act or omission which constitutes fraud in the inducement with respect to any of the Transaction Agreements or any of the Commercial Agreements, (C) apply to any action permitted or required by Section 3.12 or (D) apply to any action permitted or required by the Ongoing Litigation Agreement; provided further, however, that in the event this Agreement is terminated, this Section 3.08(e) shall be null and void and shall not operate as a waiver or release of any rights or Actions that might have been asserted or pursued but for this Section 3.08(e). Following the Effective Time, Parent shall, and shall cause the Company and its other affiliates to, cooperate with the current and former directors, officers, members of the board of managers, members, managers, consultants, advisors, agents and individuals in the employment of the Company and Newco in seeking the dismissal of any derivative suits or other suits for or on behalf of shareholders of the Company pending as of the Effective Time. (f) Following the Effective Time, Newco shall not, and shall not permit any Newco Company or any affiliate of Newco or encourage any other person to, assert any rights or pursue any Action, whether directly or on a derivative basis, against (i) Parent or any of its affiliates or (ii) any of the current or former directors, officers, members of the board of managers, members, managers, consultants, advisors, attorneys, trustees, agents or individuals in the employment of Parent or any of its affiliates (in each case, solely in their capacities as such), in each case for acts or omissions occurring prior to the Effective Time, whether known or unknown, and Newco shall not, and shall not permit any Newco Company or any affiliate of Newco to, cooperate with any person in the assertion of any such rights or pursuing any such Action except (x) as required by subpoena or other judicial or legal process or (y) as required by any inquiry by a Governmental Entity, but in each case only to the extent such inquiry or requirement to cooperate has not arisen as a result of a breach of this Section 3.08(f); provided, however, that this Section 3.08(f) shall not (A) affect any person's right to enforce any Transaction Agreement, any Commercial Agreement, any Newco I/R Agreement or any agreement entered into between the Company, Newco or any of their respective affiliates, on the one hand, and any of the R Parties or any of their respective affiliates, on the other hand, after the date of this Agreement but prior to the Effective Time or any provision herein or therein in accordance with its terms, (B) apply to any act or omission which constitutes fraud in the inducement with respect to any of the Transaction Agreements or any of the Commercial Agreements, (C) apply to any action permitted or required by Section 3.12 or (D) apply to any action permitted or required by the Ongoing Litigation Agreement; provided further, however, that in the event this Agreement is terminated, this Section 3.08(f) shall be null and void and shall not operate as a waiver or release of any rights or Actions that might have been asserted or pursued but for this Section 3.08(f). SECTION 3.09. Public Announcements. As of and after the Effective Time, Parent and its subsidiaries, including the Company, on the one hand, and Newco and its subsidiaries, on the other hand, shall consult with each other before issuing, and provide each other the opportunity to review and comment upon, any press release or other public statements with respect to the Merger or the other Transactions, and shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with any national securities exchange. A-3-12 SECTION 3.10. Standstill. From the Effective Time to the fourth anniversary of the Effective Time, Parent shall not, and Parent shall not permit any of its affiliates to, in any manner, whether publicly or otherwise, directly or indirectly, in each case, without the prior written approval of Newco (a) acquire, agree to acquire or make any proposal to acquire, directly or indirectly, any securities or assets of Newco or any subsidiary of Newco, except at the unsolicited specific written request of Newco, (b) propose to enter into, directly or indirectly, any tender or exchange offer, merger or other business combination or similar transaction involving Newco or any subsidiary of Newco, except at the unsolicited specific written request of Newco, (c) form, join or in any way participate in a "group" (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to any securities of Newco or any subsidiary of Newco, (d) enter into any discussions, negotiations, arrangements, understandings or agreements (whether written or oral) with any other person (other than financial advisors) regarding any possible purchase or sale of any securities or assets of Newco or any subsidiary of Newco, (e) make, or in any way participate, directly or indirectly, in any "solicitation" of "proxies" (as such terms are used in the proxy rules of the SEC) to vote, or seek to advise or influence any person with respect to the voting of, any securities of Newco or any subsidiary of Newco, (f) call, or seek to call, a meeting of Newco's shareholders or initiate or propose any shareholder proposal or execute any written consent with respect to Newco, (g) otherwise act, alone or in concert with others, to seek or attempt to control or influence the management, Board of Directors of Newco or policies of Newco (except to the extent conduct or settlement of litigation between R Diagnostics and the Company might be deemed such an attempt), (h) disclose any intention, plan or arrangement inconsistent with the foregoing or (i) advise, assist or encourage any other persons in connection with any of the foregoing.

SECTION 3.11. Transferred Customers. From and after the Effective Time, Newco shall assume the Company's rights and benefits under Article X of the Supply, Services and Support Agreement dated as of May 1, 2000 (the "Supply, Services and Support Agreement"), between the Company and R Diagnostics with respect to matters that occurred prior to the Effective Time.

The words "hereof", "herein", "hereby" and "hereunder" and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The words "date hereof" shall refer to the date of this Agreement. The term "or" is not exclusive. The word "extent" in the phrase "to the extent" shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply "if". The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms. Any agreement or instrument defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement or instrument as from time to time amended, modified or supplemented. References to a person are also to its permitted successors and assigns. SECTION 5.05. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any applicable Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any A-3-15 party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

This Agreement taken together with the other Transaction Agreements, the Commercial Agreements and the Letter Agreement constitutes the entire agreement, and supersedes all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof and thereof. Except for the provisions of Article II, Section 3.08 and Article IV, nothing contained in this Agreement is intended to confer upon any person other than the parties hereto and their respective successors and permitted assigns, any benefit, right or remedy under or by reason of this Agreement, provided however, that any claim under Article II by a Parent Indemnitee or a Newco Indemnitee, as the case may be, that is not a party to this Agreement shall be brought on behalf of such Parent Indemnitee or Newco Indemnitee, as the case may be, by the party to this Agreement from which such Indemnitee's status as a Parent Indemnitee or Newco Indemnitee is derived. SECTION 5.08. Certain Obligations. Whenever this Agreement requires any of the subsidiaries of any party to take any action, this Agreement will be deemed to include an undertaking on the part of such party to cause such subsidiary to take such action; provided, however, for the avoidance of doubt, at any time after the Effective Time, the Newco Companies shall not be considered to be subsidiaries of the Company.

Except as provided in Section 3.04, neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise, by any of the parties without the prior written consent of the other parties. Any purported assignment without such consent shall be void; provided, however, the parties acknowledge and agree that the conversion of Newco in accordance with Section 2.01 of the Restructuring Agreement and the continuation of Newco as a result thereof shall be deemed not to be an assignment and shall not require any consent of any party. Except as otherwise provided in Section 3.03(a), subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns. SECTION 5.11. Enforcement; Consent to Service of Process. (a) The parties agree that irreparable damage would occur and that the parties would not have any adequate remedy either pursuant to the indemnification provisions of Section 2.01 or 2.02, as the case may be, or at law in the event that any of the provisions of this Agreement, including Section 3.03, were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any New York state court or any Federal court located in the State of New York, this being in addition to any other remedy to which they are entitled at law or in equity. In addition, each of the parties hereto (i) consents to submit itself to the personal jurisdiction of any New York state court or any Federal court located in the State of New York in the event any dispute arises out of this Agreement, (ii) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (iii) agrees that it will not bring any Action relating to this Agreement in any court other than any New York state court or any Federal court located A-3-16 in the State of New York and (iv) waives any right to trial by jury with respect to any Action related to or arising out of this Agreement. (b) Parent hereby appoints the Authorized Agent as its authorized agent upon whom process may be served in any Action arising out of or relating to this Agreement or any Transaction that may be instituted in any court described in Section 5.11(a). Parent agrees to take any and all reasonable action, including the filing of any and all documents, that may be necessary to establish and continue such appointment in full force and effect as aforesaid. Parent agrees that service of process upon the Authorized Agent shall be, in every respect, effective service of process upon Parent. SECTION 5.12. Extension; Waiver. At any time the parties may (a) extend the time for the performance of any of the obligations or other acts of the other parties or (b) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights. IN WITNESS WHEREOF, Parent, the Company and Newco have duly executed and delivered this Agreement, all as of the date first herein above written. ROCHE HOLDING LTD, By /s/ DR. FRANZ B.

(a) The Company (or Parent) shall remit (or cause to be remitted) in a timely manner to the appropriate Taxing Authority all Taxes due in respect of any Tax for which the Company is required to file a Tax Return (as prepared in accordance with Section 2.03 of this Agreement and taking into account Section 3.01(c) of this Agreement) pursuant to Section 2.01(a) of this Agreement. Parent and the Company shall be liable for, shall, jointly and severally, indemnify each member of the Newco Group against, and shall be entitled to receive and retain all refunds of, all Taxes (other than Transfer Taxes, the responsibility for which is prescribed in Section 3.03 of this Agreement) of each member of the Company Group for, or attributable to, all Pre-Merger Periods; provided, however, Newco shall be liable for, shall indemnify Parent and each member of the Company Group against, and shall be entitled to receive and retain all refunds of all Non-Transaction Taxes of each member of the Company Group for, or attributable to, all Pre-Merger Periods, except to the extent that such Non-Transaction Taxes arise or result from, or otherwise relate to, any actions, inactions, omissions or disclosures taken or made by Parent (or any party related to Parent) or, after the Closing Date, by the Company or any member of the Post-Merger Company Group, except for actions, inactions, omissions or disclosures required by (X) any Transaction Agreement or (Y) applicable United States law.

Parent and the Company shall be liable for, shall indemnify each member of the Newco Group against and retain all refunds of all Taxes of each member of the Post-Merger Company Group for all Post-Merger Periods. (c) For purposes of this Agreement, including for purposes of computing the respective amounts of Taxes for which the Company, on the one hand, and Newco, on the other hand, will be responsible hereunder, the Companies agree that any and all losses, credits, allowances or other similar Tax attributes of, or allocated under applicable Tax law to, the Company (or any member of the Company Group) arising in, or attributable to, any Pre-Merger Period (collectively, "Company Attributes") shall be used first to offset income, profits or gains of the Company (or any member of the Company Group) that arise in, or are attributable to, any Pre-Merger Period and that do not directly or indirectly result from, arise in connection with or otherwise relate to the Preliminary Transactions, the Restructuring or the Merger. For the avoidance of doubt, any Company Attributes remaining after the application of the immediately preceding sentence shall be used by the Company (or any member of the Company Group or Post-Merger Company Group) to offset (i) income, profits or gains that give rise to any Transaction Taxes and (ii) income, profits or gains that arise in, or are attributable to, any Post-Merger Period. (d) (i) To the extent permitted by law or administrative practice, the taxable year of any member of the Company Group that includes the Effective Time shall be treated as closing on (and including) the Closing Date.

(ii) Where it is necessary to apportion between Newco, on the one hand, and the Company, on the other hand, the Tax liability of an entity for a Straddle Period which is not treated under this Section 3.01(d) as closing on the Closing Date, such liability shall be apportioned between the Pre-Merger Period and the Post-Merger Period on the basis of a "deemed" interim closing of A-4-6 the books, except that Taxes (such as real property Taxes) imposed on a periodic basis shall be allocated on a daily basis. For the avoidance of doubt, Parent and the Company shall be solely liable for, shall, jointly and severally, indemnify each member of the Newco Group against, and shall be entitled to receive and retain all refunds of all Transaction Taxes.

In the case where a member of the Newco Group is not the Responsible Party, Newco will be liable for, shall indemnify Parent and each member of the Company Group against, and shall be entitled to receive refunds of one-half of the applicable Transfer Taxes. SECTION 3.04. Tax Obligations Arising Under a Pre-Merger Period Tax Sharing Agreement.

SECTION 5.02. Tax Proceedings. (a) Notification. Within 15 days after a party (the "Indemnitee") becomes aware of the existence of a Tax issue (an "Indemnity Issue") that may give rise to an indemnification claim under Article III or Section 5.01 of this Agreement (a "Tax Controversy"), by it against the other party (the "Indemnifying Party"), the Indemnitee shall promptly notify the Indemnifying Party of the Indemnity Issue, and thereafter shall promptly forward to the Indemnifying Party copies of notices and communications with a Taxing Authority relating to such Tax Controversy (including, without limitation, any IRS revenue agent's reports or similar reports, notices of proposed adjustment, or notices of deficiency). (b) Control of Tax Proceedings. The Indemnifying Party may elect to control, and may elect to have sole discretion in handling, settling or contesting any audit inquiry, information request, audit proceedings, suit, contest or any other action with respect to a Tax Controversy for which it would be required to indemnify the other party if it acknowledges in writing that it has sole liability for any Taxes that might arise in such proceeding. Notwithstanding anything to the contrary herein, the Indemnifying Party shall, upon the written request of the Indemnitee, keep the Indemnitee informed of all material developments relating to the applicable Tax Controversy and the Indemnitee may, at its own cost and expense and with its own counsel, monitor and participate in (but not control) the defense of such applicable Tax Controversy. The Indemnifying Party shall not admit any liability with respect to, or settle, compromise or discharge, any Tax proceeding with respect to a Tax Controversy on a basis that would adversely affect the Indemnitee without obtaining the Indemnitee's written consent, which consent shall not be unreasonably withheld, conditioned or delayed; provided, however, if the Indemnitee unreasonably withholds such consent to any such settlement, compromise or discharge recommended by the Indemnifying Party, then the Indemnifying Party (i) shall not in any event be obligated to indemnify the Indemnitee, or otherwise be responsible, for any amount in excess of the amount of the settlement, compromise or discharge so recommended by the Indemnifying Party and (ii) shall be entitled to reimbursement of the fees and expenses of counsel incurred by the Indemnifying Party after the date on which the recommendation was made to the Indemnitee in the event the final and unappealable judgment in such Tax Controversy exceeds the amount of the settlement, compromise or discharge so recommended. The Indemnitee shall not admit any liability with respect to, or settle, compromise or discharge, any Tax Controversy without obtaining the Indemnifying Party's written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Any out-of-pocket costs incurred in handling, settling or contesting a Tax Controversy shall be borne by the Indemnifying Party. SECTION 5.03. Indemnification Payments. (a) If an Indemnitee has a claim for an indemnification payment from an Indemnifying Party under this Agreement, the Indemnitee shall promptly provide to the Indemnifying Party notice of such claim, including a description of such claim and a detailed calculation of the amount of the indemnification payment that is claimed. The Indemnifying Party shall pay the amount of such indemnification obligation to the Indemnitee no later than 10 business days prior to the Due Date for the payment of the relevant Tax or 10 business days after the Indemnifying Party receives the Indemnitee's calculations of the Indemnifying Party's indemnification obligation hereunder, whichever occurs last, unless the Indemnifying Party reasonably disputes the amount of, or its liability for, such payment. Interest shall accrue with respect to any indemnification payment (including, without limitation, A-4-9 any disputed payment that is ultimately required to be made) not made within the period provided for payment, at the Underpayment Rate in effect under the Code at such time. (b) The amount of all indemnification obligations under this Agreement (other than the Distribution Gain Payment) shall be calculated on an after-tax basis (without taking into account any net operating loss or other similar tax credit or item available to offset such amount). Any payments made to one party by another party pursuant to this Agreement shall be treated for all Tax purposes as nontaxable payments (distributions or capital contributions, as the case may be) made immediately prior to the Merger, unless, and then only to the extent, otherwise required by a Final Determination. (c) All indemnification payments under this Agreement shall be reduced to take account of the present value of any net Tax benefit (including, but not limited to, any current or future deductions, any reduction of income or gain upon a sale, disposition, conveyance, license or other similar transaction as a result of increased Tax basis, any Tax refunds received, any use of a credit of Taxes and any increase in the amount of losses, reliefs, allowances or other similar Tax attributes) realized by the Indemnitee in connection with or otherwise arising (directly or indirectly) from a Tax Controversy. Upon the written request of the Indemnifying Party, the Indemnitee shall provide the amount of the Tax benefit realized by the Indemnitee in connection with or otherwise arising (directly or indirectly) from a Tax Controversy together with reasonable detail with respect to such calculation. In computing the amount of any such Tax benefit, the Indemnitee shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt of any indemnification payment hereunder or from a Tax Controversy. The Indemnitee shall cooperate fully with all commercially reasonable requests from the Indemnifying Party in connection with determining the present value of such net Tax benefit. SECTION 5.04. Cooperation and Exchange of Information. (a) Each member of the Company Group, Post-Merger Company Group, and the Newco Group shall cooperate fully with all reasonable requests from the other party in connection with the preparation and filing of Tax Returns, claims for refund, and Tax proceedings concerning issues or other matters covered by this Agreement. Such cooperation shall include, without limitation: (i) the retention until the expiration of the applicable statute of limitations (taking into account any extensions or waivers thereof), and the provision upon request, of Tax Returns, books, records (including, without limitation, information regarding ownership and Tax basis of property), documentation and other information relating to the Tax Returns, including accompanying schedules, related work papers, and any other documents relating to rulings or other determinations by Taxing Authorities; (ii) the execution of any document that may be necessary or reasonably helpful in connection with any Tax proceeding, or the filing of a Tax Return or refund claim by a member of the Company Group or Newco Group, including certification, to the best of a party's knowledge, of the accuracy and completeness of the information it has supplied; and (iii) the use of the parties' reasonable best efforts to obtain any documentation that may be necessary or reasonably helpful in connection with any of the foregoing.

(b) If a party fails to comply with any of its obligations set forth in Section 5.04(a) of this Agreement upon reasonable request and notice by the other party, and such failure results in the imposition of additional Taxes, the nonperforming party shall be liable in full for such additional Taxes. SECTION 5.05. Retention of Information. Without limiting Section 5.04(a)(i) of this Agreement, if a party wishes to dispose of documentation of the Company or Newco or any member of its respective Group, including, without limitation, books, records, Tax Returns and all supporting schedules and information relating thereto after the expiration of the applicable statute of limitations (taking into account A-4-10 any extensions or waivers thereof), then it shall provide written notice to the other party describing the documentation to be destroyed or disposed of 60 days prior to taking such action.

If the parties are unable to resolve such dispute within 30 days thereafter, such dispute shall be resolved by a nationally recognized law firm or independent accounting firm mutually acceptable to the Company and Newco or, if the Company and Newco are not able to so agree within 10 days after the end of such 30-day period, then the Company and Newco shall each select such a firm and such firms shall jointly select a third nationally recognized law firm or independent accounting firm to resolve the disputed matter (such firm or firms, the "Neutral Expert").

The words "hereof", "herein", "hereby" and "hereunder" and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The words "date hereof" shall refer to the date of this Agreement. The term "or" is not exclusive.

References to a person are also to its permitted successors and assigns. SECTION 6.05. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any applicable Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible. SECTION 6.06. Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties.

SECTION 6.08. Certain Obligations. Whenever this Agreement requires any of the subsidiaries of any party to take any action, this Agreement will be deemed to include, without limitation, an undertaking on the part of such party to cause such subsidiary to take such action; provided, however, for the avoidance of doubt, at any time after the Effective Time, Newco and its subsidiaries shall not be considered to be subsidiaries of the Company. SECTION 6.09. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof.

Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise by any of the parties without the prior written consent of the other parties. Any purported assignment without such consent shall be void; provided, however, the parties acknowledge and agree that the conversion of Newco in accordance with Section 2.01 of the Restructuring Agreement and the continuation of Newco as a result thereof shall be deemed not to be an assignment and shall not require any consent of any party. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns. SECTION 6.11. Enforcement; Consent to Service of Process. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.

SECTION 6.12. Extension; Waiver. At any time prior to the Restructuring, the parties may (a) extend the time for the performance of any of the obligations or other acts of the other parties or (b) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

Each of the Parties, for itself and its Affiliates, agrees not to take any action before the Termination Date in derogation of or inconsistent with the obligations specified in this Agreement, including filing or prosecuting (other than requesting or providing for service of process and indicating an intention to defend as contemplated by Section 2.3) any inter partes or ex parte proceedings anywhere in the world in any court, patent office or other governmental relating to the subject matter of the IGEN/Roche Actions or to any of the patents that are the subject of any of the IGEN/Roche Actions, or any patent in any country claiming priority to any of the applications to which the patents in suit claim priority. 3.3 Covenant Not To Sue. IGEN agrees that it shall not commence any new patent suit or prosecute any patent suit against Roche for any acts of Roche occurring between the date of the termination of the License Agreement through to (but not subsequent to) the Termination Date that, if taken prior to termination of the License Agreement, would have been within the scope of the license granted under the License Agreement. Nothing in this Agreement shall preclude IGEN or any of its Affiliates from asserting or filing, and IGEN for itself and each of its Affiliates reserves the right to assert and file, any claim, suit, action and proceeding against Roche and any of its Affiliates for any acts taken after the date of the termination of the License Agreement that are not within the scope of the license granted under the License Agreement. 3.4 Compliance with Judgment.

The Parties agree that nothing in this Agreement can be construed as a waiver of any rights, and is without prejudice to the ability, of both Parties to prosecute the IGEN/Roche Actions, and any other actions not prosecuted as a result of this Agreement, after the Termination Date. Without limiting the generality of the foregoing, Roche covenants and agrees that it shall not, and shall not permit any of its Affiliates, to argue or assert that the period between the date of this Agreement and the Termination Date constitutes undue or unreasonable delay (or advancing any similar or comparable argument) in IGEN's filing for or seeking a motion for a preliminary injunction or an interlocutory A-5-4 injunction in either of the IGEN/Roche Actions or that any such motion was not timely filed as a result of IGEN's complying with its obligations under this Agreement.

Wohlstadter Meso Scale Technologies, LLC., JW Consulting Services, L.L.C. and Jacob N. Wohlstadter Dear Mr. Wohlstadter: As you are aware, IGEN International, Inc., a Delaware corporation ("IGEN"), and Roche Holding Ltd, a joint stock company organized under the laws of Switzerland ("PARENT"), have agreed to enter into certain transactions, which include: (i) the merger of 66 Acquisition Corporation II ("MERGER SUB"), a Delaware corporation and wholly-owned subsidiary of Parent, with and into IGEN pursuant to the Agreement and Plan of Merger, dated as of the date hereof (the "MERGER AGREEMENT"), among IGEN, IGEN Integrated Healthcare, LLC, a Delaware limited liability company ("NEWCO"), Merger Sub and Parent (the "MERGER"), (ii) the transfer, prior to the Merger, of certain of IGEN's assets to Newco (or to one or more of Newco's subsidiaries), the assumption by Newco (or one or more of Newco's subsidiaries) of certain of the liabilities of IGEN, and the conversion of Newco from a Delaware limited liability company to a Delaware corporation pursuant to the Restructuring Agreement, dated as of the date hereof, between IGEN and Newco (the "RESTRUCTURING"), and (iii) the execution and delivery of certain other transaction agreements in connection with the foregoing. As part of the Restructuring, IGEN has agreed to contribute, transfer and assign to Newco all of IGEN's right, title and interest in and to the agreements previously entered into by two or more of the parties to this letter agreement, as set forth on SCHEDULE 1 attached hereto (collectively, the "JOINT VENTURE DOCUMENTS"), and Newco has agreed to assume all obligations and liabilities of IGEN under the Joint Venture Documents. In connection with the Proposed Transactions (as defined herein) and as a condition to their willingness to execute and deliver the Merger Agreement and the other agreements referenced above, IGEN and Parent have requested that Meso Scale Diagnostics, LLC. ("MSD"), Meso Scale Technologies, LLC. ("MST"), Jacob N. Wohlstadter ("JW") and JW Consulting Services, L.L.C. ("JWCS") execute and deliver one or more of the documents listed on SCHEDULE 2 to this letter agreement, including the Global Consent and Agreement, dated as of the date hereof, among Parent, IGEN, Newco, MSD, MST, JW and JWCS (the "GLOBAL CONSENT"). In consideration of the execution and delivery of such documents by MSD, MST, JW and JWCS, (i) IGEN and MST hereby agree to extend the expiration of the term of the Joint Venture Agreement as set forth in Section 8.1 thereof in accordance with the terms of this letter agreement (but not IGEN's obligation to provide funding to MSD under the Joint Venture Agreement other than pursuant to the terms of this letter agreement), (ii) Newco hereby agrees to make or cause to be made to MSD by wire transfer the Closing Payment (as defined herein), and IGEN hereby agrees to provide Interim Funding (as defined herein) to MSD, in accordance with the terms of this letter agreement and (iii) the parties to this letter agreement hereby agree to be bound by the other agreements and understandings set forth in this letter agreement. For purposes of this letter agreement, "PROPOSED TRANSACTIONS" shall have the same meaning as the term "Transactions" as defined in the Global Consent. A-7-1 1. Closing Payment and Interim Funding. In the event the Merger is consummated, on the first business day following the date of the Effective Time (as defined in the Merger Agreement) of the Merger, Newco shall make or cause to be made to MSD by wire transfer a Class C capital contribution in the amount of U.S. $37.5 million (the "CLOSING PAYMENT"); provided, however, that in the event the date of the Effective Time has not occurred prior to December 1, 2003 (the expiration of IGEN's existing obligation to provide committed funding to MSD under the approved 2003 budget), IGEN shall provide continued funding to MSD to be paid monthly on the first day of each month commencing on December 1, 2003 in an amount per month equal to 1/12 of the aggregate committed funding of IGEN under the approved 2003 budget pursuant to the Joint Venture Agreement (the "INTERIM FUNDING") until the earlier to occur of (i) the date of the Effective Time or (ii) the termination of the Merger Agreement in accordance with its terms, which Interim Funding shall reduce the amount of any Closing Payment and shall be treated as a Class C capital contribution to MSD. In the event the date of the Effective Time does not occur, MSD shall not have any obligation to repay any amounts provided to MSD as Interim Funding pursuant to this letter agreement or otherwise (except to the extent IGEN is entitled to receive distributions on the Class C interests pursuant to the Joint Venture Documents). 2. Assignment of IGEN's Rights Hereunder to Newco. MST, MSD, JWCS and JW acknowledge that, upon the effectiveness of the Restructuring, this letter agreement, and all of IGEN's rights and obligations hereunder, shall be assigned by IGEN to Newco. 3. Consents. IGEN consents to MSD and MST granting the consents and joining in the licenses as set forth in the Consent to License Agreement. 4. Joint Venture Agreement Extension. Notwithstanding anything in the Joint Venture Agreement to the contrary, the term of the Joint Venture Agreement as set forth in Section 8.1 thereof shall expire on the later of (i) November 30, 2003 or (ii) the earlier of (a) the date of the Effective Time or (b) the termination of the Merger Agreement prior to the Effective Time in accordance with its terms; provided that IGEN's obligation to provide funding to MSD under the Joint Venture Agreement beyond November 30, 2003 shall not be extended other than pursuant to the terms of this letter agreement. 5. Developments. IGEN confirms and agrees that it will deliver a copy of all tangible items and electronic records or files included within the Developments (as defined in Section 3.6 of the Joint Venture Agreement) to MSD, and, upon MSD's request, agrees to provide MSD with reasonable access to copies of tangible items and electronic records or files included within the Developments in IGEN's possession or control. 6. Confidentiality. Notwithstanding the terms and conditions of any of the Joint Venture Documents, MSD may disclose the terms and conditions of one or more of the Joint Venture Documents and Confidential Information (as defined in Section 5.1 of the Joint Venture Agreement) to one or more third parties in connection with a proposed sale, acquisition, merger, financing or other similar transaction (including strategic collaborations) involving MSD (including disclosure of such information as required by a governmental rule or regulation and/or as reasonably requested by a third party to conduct a due diligence review) so long as (i) MSD provides written notice of such disclosure or proposed disclosure (any such notice to be kept confidential by the recipient thereof and not to be disclosed to any third party) to IGEN or, from and after the Effective Time, if any, Newco, no later than 30 days following such disclosure or, if earlier, its agreement to provide such disclosure, and (ii) each third party agrees to maintain the disclosed terms and conditions of the Joint Venture Documents and Confidential Information as confidential and to not disclose such information to any third party other than its attorneys, accountants and other professional advisors who agree to maintain such information as confidential and to not further disclose such information to any third party. 7. Confirmation Regarding Treatment of Options. IGEN confirms and agrees that (i) on May 9, 1997 IGEN granted to JW a ten-year non-qualified stock option to purchase 180,000 shares of common stock of IGEN at the exercise price per share specified therein and (ii) effective August 1, 2000 IGEN granted to JW a ten-year non-qualified stock option to purchase 75,000 shares of common stock of IGEN A-7-2 at the exercise price per share specified therein, pursuant to IGEN's 1994 Stock Option Plan (collectively, the "JW OPTIONS"). Consistent with Section 7.04 of the Merger Agreement, such JW Options shall be deemed "Company Stock Options" and shall be cancelled upon the occurrence of the Effective Time and JW, as the holder of such options, shall be entitled to receive the consideration described therein as payable to holders of Company Stock Options. 8. Representations and Warranties. Each of the parties to this letter agreement represents and warrants to the other parties to this letter agreement that the execution, delivery and performance of this letter agreement have been duly authorized by such party (including in the case of IGEN, by the Joint Venture Operating Committee of the Board of Directors of IGEN), that this letter agreement constitutes a valid and binding obligation of such party, enforceable in accordance with its terms, that such party has the right, power and authority to grant the rights and perform the obligations hereunder and under the Joint Venture Documents, and that neither the execution and delivery of this letter agreement nor the consummation of the performance of such party's obligations under this letter agreement constitutes a violation of, or default under, or conflicts with, (i) any terms of the articles of incorporation, bylaws or other organizational documents, as applicable, of such party, (ii) any order, judgment or decree of any court or governmental body binding upon or affecting such party, or (iii) any contract, commitment or other agreement or understanding to which such party is a party or by which it is bound. 9. Termination. In the event the Merger Agreement is terminated pursuant to its terms prior to the Effective Time, this letter agreement shall automatically and simultaneously terminate. In the event of such termination, no party shall have any liability to any other party pursuant to this letter agreement, except that IGEN will remain liable for any accrued and unpaid Interim Funding as of the date of such termination. It is understood that consummation of the Merger shall not constitute a termination of this letter agreement. 10. Miscellaneous. This letter agreement and the terms and conditions hereof (including payments to be made after the date hereof) shall survive the expiration of the term of the Joint Venture Agreement or the termination for any reason of the Joint Venture Agreement. This letter agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. This letter agreement may not be assigned by any party without the prior written consent of the other parties hereto, except (i) that the parties acknowledge and agree that the conversion of Newco in accordance with Section 2.01 of the Restructuring Agreement (as defined in the Merger Agreement) and the continuation of Newco as a result thereof shall be deemed not to be an assignment and shall not require the consent of any party and (ii) for the assignment by IGEN to Newco or an assignee described in the foregoing clause (i) in accordance with the provisions of paragraph 2 above. This letter agreement shall be deemed to modify and amend the Joint Venture Documents to the extent necessary to reflect the matters addressed in this letter agreement. It is agreed that the parties to this letter agreement shall be entitled, in addition to any and all other remedies, to an injunction or injunctions to prevent breaches of this letter agreement and to enforce specifically the terms and provisions of this letter agreement. This letter agreement shall be governed by and construed in accordance with Delaware law (excluding choice of law principles) except for those provisions applicable to a specific Joint Venture Document, in which case the governing law provision set forth in such Joint Venture Document shall apply. Any provision of this letter agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this letter agreement, or, in the case of a waiver, by the party against whom the waiver is to be effective. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

Dispute Resolution; Venue And Choice Of Law. 6.1 Good Faith Resolution. In the event that at any time during the Term of this Agreement a disagreement, dispute, controversy or claim should arise out of or relating to the interpretation of this Agreement, or performance by a Party under this Agreement, or a breach of this Agreement by a Party, or any claim by a Party that any provision of this Agreement is invalid (a "Dispute" or collectively "Disputes") , one Party shall give written notice to the other Party that a dispute exists and the Parties will then attempt in good faith to resolve their differences before resorting to arbitration provided in Section 6.2. If the Parties cannot resolve the disputed matter within thirty (30) days after such notice, then either Party shall be free to submit the disputed matter to binding arbitration in accordance with Section 6.2 hereof. For purposes of this Article 6, the terms "Party" and "Parties" shall include each of the signatories to this Agreement and/or any one or more of their respective Affiliates, whether the reference is to a Party as a claimant or a Party against which a claim is made. 6.2 Arbitration. (a) The Parties intend Section 6.2 hereof to be enforceable in accordance with the Federal Arbitration Act (9 U.S.C. Section 1, et seq.), including any amendments to that Act which are subsequently adopted, notwithstanding any other choice of law provision set forth in this Agreement. In the event that either Party refuses to submit to arbitration as required herein, the other Party may request a United States District Court to compel arbitration in accordance with the Federal Arbitration Act. (b) Any dispute or other matter in question between LLC and IGEN arising out of or relating to the formation, interpretation, performance, or breach of this Agreement, whether such dispute or matter arises before or after termination of this Agreement, shall be resolved solely by arbitration if the Parties are unable to resolve the dispute through negotiation pursuant to Section 6.1 hereof. Arbitration shall be initiated by the delivery of a written notice of demand for arbitration by one Party to the other. The date on which the other Party receives such written notice shall be hereinafter referred to as the "Arbitration Notice Date." A-10-9 (c) Each Party shall appoint an individual as arbitrator and the two so appointed shall then appoint a third arbitrator. If either Party refuses or neglects to appoint an arbitrator within thirty (30) days after the Arbitration Notice Date, then the arbitration shall be conducted by a single arbitrator appointed by the American Arbitration Association. If two arbitrators are appointed but do not agree on the third arbitrator within sixty (60) days after the Arbitration Notice Date, each of the arbitrators shall nominate within sixty-seven (67) days after the Arbitration Notice Date three individuals. Each arbitrator shall then within seventy-two (72) days after the Arbitration Notice Date decline two of the nominations presented by the other arbitrator. The third arbitrator shall then be chosen from the remaining two nominations by drawing lots. Notwithstanding anything contained herein to the contrary, if the third arbitrator is not chosen with seventy-two (72) days after the Arbitration Notice Date, then the American Arbitration Association shall appoint the third arbitrator within seventy-seven (77) days after the Arbitration Notice Date. The arbitrators shall not be or have been affiliated with, or have any personal, financial or business relationship with, either of the Parties or any Affiliate of either Party; the arbitrators shall not have a personal or financial interest in the result of the arbitration. (d) The arbitration hearings shall be held in Borough of Manhattan, State of New York or such other place as may be mutually agreed by the Parties, shall be conducted in the English language and shall be conducted as confidential proceedings (except to the extent necessary to enforce the award resulting therefrom). Unless the Parties agree otherwise, the arbitrators shall commence the arbitration hearing within thirty (30) days after the selection of the third arbitrator. The arbitrators shall issue orders to protect the confidentiality of proprietary information, trade secrets and other sensitive information disclosed. Pending the arbitration hearing, at the request of a Party, the arbitrators may issue temporary injunctive or other equitable relief to address any violation or threatened violation of this Agreement. All awards shall be made based on a majority vote of the arbitrators, shall be in writing, shall not be considered confidential information of either Party, shall be issued within sixty (60) days after hearings before the arbitrators are completed, and shall state the reasoning on which the award rests unless the Parties agree otherwise. In addition to any relief at law which may be available to an aggrieved Party for such breach, such Party shall be entitled to injunctive and other equitable relief as the arbitration panel may grant. The arbitrators shall deliver a copy of the award to each Party personally or by registered mail. Any party may request within ten (10) days after receiving the decision that, for good cause, the arbitrators reconsider and modify such decision. The arbitrators shall have thirty (30) days after such request to modify their decision, if they consider it appropriate. Thereafter, the decision of the arbitrators shall be final, binding and nonappealable, except to the extent appeals are permitted by the Federal Arbitration Act, with respect to all persons, including (without limitation) persons who have failed or refused to participate in the arbitration process. Judgment upon the award rendered may be entered in any court having jurisdiction thereof. (e) Each Party shall bear its own costs in connection with any such arbitration including, without limitation, (i) all legal, accounting, and any other professional fees and expenses, (ii) the fees and expenses of its own arbitrator, and (iii) all other costs and expenses each Party incurs to prepare for such arbitration. Other than set forth above, each side shall pay, (iv) one-half of the fee and expenses of the third arbitrator, and (v) one-half of the other expenses that the Parties jointly incur directly related to the arbitration proceeding. (f) Except as provided above, arbitration shall be based upon the Commercial Arbitration Rules of the American Arbitration Association. Discovery shall be limited at the discretion of the arbitrators, so that the timing and extent of such discovery shall not interfere with the normal business operations of the Parties. The arbitrators may proceed to an award notwithstanding the failure of either Party to participate in the proceedings. A-10-10 (g) In the event of subsequent actions or proceedings to confirm the award or to enforce the judgment entered thereon or any other rights flowing therefrom, the prevailing Party shall be entitled to recover its reasonable attorney's fees incurred in such actions or proceedings. (h) The fact that the dispute resolution procedures specified in this Article 6 shall have been or may be invoked shall not excuse any Party from performing its obligations under this Agreement, and during the pendency of any such procedure the Parties shall continue to perform their respective obligations in good faith. 6.3 Limited Recourse to Courts. This Article 6 shall be the exclusive dispute resolution procedure for Disputes under this Agreement and no Party shall bring Disputes before any court, except as appeals to arbitration awards are permitted by Section 6.2. Except as permitted by Section 6.2, the Parties hereby waive any right to appeal an arbitration award to any court. The provisions of Section 6.2 may be enforced, and judgment on the award (including without limitation equitable remedies) granted in any arbitration hereunder may be entered, in any court of competent jurisdiction. The Parties hereby submit to the non-exclusive in personam jurisdiction of the federal courts in New York for such purposes. THE PARTIES HEREBY WAIVE ANY AND ALL RIGHTS TO TRIAL BY JURY FOR MATTERS RELATED TO DISPUTES SUBMITTED TO ANY COURT. 6.4 Governing Law. This Agreement is made in accordance with and shall be governed and construed under the laws of the State of New York, U.S.A., without regard to its conflicts of laws rules. 7. Term And Termination. 7.1 Term. This Agreement shall remain in full force and effect for the Term, unless terminated earlier in accordance with Section 7.2 below. 7.2 Termination for Cause. (a) LLC may, in its sole discretion, terminate this Agreement, effective after the grace periods described below, by giving written notice of such termination to IGEN, if IGEN fails materially to comply with any material obligation of this Agreement, and IGEN fails to cure such breach within sixty (60) days after written notice thereof by LLC or, if such breach cannot reasonably be cured within sixty (60) days, IGEN fails to commence to cure such breach within said sixty-day period and diligently continue to cure such breach, unless otherwise specified in this Agreement; provided, however, that if IGEN is unable to cure a breach due to Force Majeure, then such 60-day period shall be extended for a period of time reasonable under the circumstances. If there should be a dispute between the parties as to whether a breach exists which entitles LLC to terminate for cause, the matter shall be resolved promptly under the provisions of Article 6 hereof and all attempts to terminate shall be stayed. Upon termination by LLC, all payments then outstanding under this Agreement and payable by LLC shall become immediately due and payable. (b) (i) From time to time during the term of this Agreement, LLC may in advance of first sale, placement or other commercialization of a proposed product that uses or incorporates Licensed ECL Technology, request in writing that IGEN confirm that such proposed product is a Product. At Roche's request, IGEN shall confirm in writing receipt of such notice. This request process described in this Section 7.2(b)(i) is only available on a product-by-product basis. A single request under this process shall not apply to groups or ranges of products. Each such request shall include sufficient information to enable IGEN to make a determination of whether the proposed product is a Product. If IGEN does not respond within sixty (60) days of its receipt of such request, IGEN shall be deemed to have responded that the proposed product is not a Product. If IGEN responds that the proposed product is not a Product and LLC disagrees with such response, a dispute as to the interpretation of this Agreement shall be deemed to exist. This dispute shall be resolved in accordance with Article 6 hereof. If the final result in the dispute resolution is that such proposed product is not a Product, and such proposed product is A-10-11 subsequently sold, placed or otherwise commercialized by or on behalf of LLC or any of its Affiliates, that sale, placement or commercialization shall be considered a material breach of this Agreement by LLC and IGEN shall have the right to terminate this Agreement upon delivering written notice to LLC, effective immediately. LLC shall have no right to cure such a breach or to challenge or seek any review, by arbitration or otherwise, of such termination. (ii) If LLC or any of its Affiliates sells, places or otherwise commercializes an instrument that uses or incorporates Licensed ECL Technology (that previously had not been the subject of the process described in Section 7.2(b)(i) above) which IGEN believes is not an ECL Instrument, then IGEN may deliver a notice of immediate termination to LLC. LLC shall have no right to cure such a breach. If there should be a dispute between the Parties as to whether such a breach has occurred, the matter shall be resolved promptly under Article 6 and all attempts to terminate shall be stayed. Termination shall be effective immediately, and without any further action by IGEN, the final result pursuant to Article 6 is that such instrument used or incorporated Licensed ECL Technology and was not an ECL Instrument. (iii) If LLC or any of its Affiliates sells, places or otherwise commercializes an assay that uses or incorporates Licensed ECL Technology (that previously had not been the subject of the process described in Section 7.2(b)(i) above), which assay IGEN believes is not an ECL Assay, then IGEN may deliver a notice of breach to LLC. Upon LLC's receipt of such notice (the "Notice Date"), the Parties agree to appoint a single arbitrator within ten (10) days after the Notice Date; provided, however, that if an arbitrator is not jointly appointed by such date, the American Arbitration Association shall appoint such arbitrator. Unless the Parties agree otherwise, the arbitrator shall commence the arbitration hearing within thirty (30) days after its appointment to determine whether or not the assay in question is or is not an ECL Assay. Such hearing shall last no longer than five (5) consecutive business days, during which the Parties shall present their positions on the matter in question. The arbitrator shall be directed to issue its decision within thirty (30) days after the end of the hearing. Except for the time periods specified in this Section 7.2(b)(iii), Section 6.2 shall apply to the arbitration described in this Section 7.2(b)(iii). If the final result pursuant to such arbitration is that the assay in question is an ECL Assay, LLC shall not be in breach of this Agreement. If the final result pursuant to such arbitration is that the assay in question is not an ECL Assay, then such sales of such assays shall not constitute a breach of this Agreement if: (A) all sales by or on behalf of LLC or its Affiliates of such assay shall cease within twenty (20) business days after determination of the final result pursuant to Section 6.2; and (B) LLC and its Affiliates shall assign or sublicense, as the case may be, to IGEN all patents, patent applications and other intellectual property rights for the analyte-specific reagent for such assay (and the analyte-specific reagent assay method) which LLC and its Affiliates owns or has licensed, with the right to sublicense. If LLC or any of its Affiliates continues to sell, place or otherwise commercialize such assay after the date which is twenty (20) business days after determination of the final result pursuant to Section 6.2, LLC shall have committed a material breach of this Agreement and IGEN shall have the right to immediately terminate this Agreement upon delivering written notice to LLC. LLC shall have no right to cure such a breach or to challenge or seek any review, by arbitration or otherwise, of such termination. (iv) Neither Party shall have the right to seek or obtain injunctive or equitable relief or to otherwise initiate proceedings at law in order to prevent, delay or limit: (A) any of the arbitration proceedings contemplated by this Section 7.2(b); or (B) IGEN's termination of LLC if such termination is permitted under the terms of this Section 7.2(b). (c) In the event LLC breaches any of its obligations hereunder, then IGEN shall be entitled to seek and obtain both monetary damages, specific performance of this Agreement and/or equitable or injunctive relief, but, except as described in Section 7.2(b) above, IGEN shall not be entitled to seek or obtain a termination of this Agreement. A-10-12 7.3 Effect of Termination. Upon termination of this Agreement for cause prior to the expiration of the Term set forth in Section 7.1 hereof, and upon expiration of this Agreement at the end of its Term, all licensed rights under Section 2 of this Agreement shall cease. Notwithstanding any expiration or termination, the provisions of Sections 2.5 (with respect to obligations that accrue prior to termination), 3, 5, 6, 7.3, 8, 9, 10, 11, 12, 13 and 14 shall survive. LLC may, in the case of termination of this Agreement, market and sell a reasonable inventory of Products existing at the time of such termination in the Field; provided however, that such sell-off period shall be limited to nine (9) months following the date of termination and all of such sales shall be conducted in accordance with and subject to the limitations of this Agreement. 7.4 Bankruptcy. LLC shall retain the rights granted to it as a licensee under Section 365(n) of the United States Bankruptcy Code in case of the bankruptcy, insolvency or winding-up of IGEN. 8. No Patent Warranty. IGEN specifically excludes any representation or warranty, express or implied, that IGEN will successfully obtain any patent. 9. Indemnification, Liability, Infringement. 9.1 Defense of Third Party Infringement Actions. If the manufacture, production, sale, or use of any Product results in a claim, suit or proceeding brought by a third party (each, an "Action") alleging patent infringement against LLC or IGEN (or any of their respective Affiliates), such party shall promptly notify in writing the other party. The party subject to such Action (the "Controlling Party") shall have the exclusive right and obligation to defend and control the defense of any such Action using counsel of its own choice; provided that the Controlling Party shall not enter into any settlement of such Action without the written consent of the other party, which consent may be withheld in the unfettered discretion of the other party if such settlement admits the invalidity or unenforceability of any patent rights of the other party, and otherwise may not be unreasonably withheld. The Controlling Party agrees to keep the other party reasonably informed of all material developments in connection with any Action. 9.2 Suits for Infringement by Others. In the event either party becomes aware of any actual or threatened infringement of any Licensed ECL Technology by any third party, that party shall promptly notify the other party, and the parties shall discuss the most appropriate action to take. IGEN shall have the sole right to bring, at its own expense, an infringement action against the third party infringer and shall be entitled to keep any awards made in such proceeding. LLC may elect to appear as a party to the suit and shall, at IGEN's request, assist IGEN without expense to IGEN. 9.3 Product Liability Indemnity. LLC expressly and unequivocally agrees to and hereby does indemnify, release, defend and hold IGEN (and its Affiliates, sublicensees and licensors and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of the heirs, executors, successors and assigns of the foregoing) harmless from and against all claims, damages, losses, costs and expenses, including reasonable attorneys' fees, arising in favor of any person, firm or corporation resulting from or arising out of liability in any way relating to the Products sold, placed or otherwise commercialized by LLC or its Affiliates or any Authorized Third Parties, including without limitation, the manufacture, packaging, use, sale or other distribution of Products by LLC or its Affiliates or sublicensees, or any representation made or warranty given by LLC with respect to any Product provided that IGEN (a) gives LLC notice of such claim, (b) cooperates with LLC, at the LLC's expense, in the defense of such claim, and (c) gives LLC the right to control the defense and settlement of any such claim, except that LLC shall not enter into any settlement that affects IGEN's rights or interest without IGEN's prior written approval. IGEN shall have no authority to settle any claim on behalf of LLC. LLC agrees to maintain proper product liability insurance policies, reasonably acceptable to IGEN, everywhere it sells Products and to furnish satisfactory evidence of same upon request by IGEN from time to time. A-10-13 9.4 Waiver of Claims. LLC shall not assert, and LLC shall insure that its Affiliates Sublicensees do not assert, any claims against IGEN and its licensors for any matter for which LLC has provided indemnity to IGEN under Sections 9.3 and 9.5 hereof. LLC shall indemnify, hold harmless and defend IGEN and its licensors against any such claims. 9.5 Breach by Affiliate Sublicensee or Authorized Third Party. Failure of an Affiliate Sublicensee or Authorized Third Party to adopt and satisfy a condition stated in this Agreement applicable to LLC or an Affiliate Sublicensee or Authorized Third Party, as the case may be, shall be considered a breach of this Agreement by LLC. LLC and such Affiliate Sublicensee shall be jointly and severally responsible for and indemnify IGEN and its Affiliates (and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of the heirs, executors, successors and assigns of the foregoing) against any loss, cost, damage or liability (including reasonable attorneys' fees) arising from the breach by such Affiliate Sublicensee of this Agreement. LLC shall indemnify IGEN and its Affiliates (and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of the heirs, executors, successors and assigns of the foregoing) against any loss, cost, damage or liability (including reasonable attorneys' fees) arising from the failure by an Authorized Third Party to adopt and satisfy a condition stated in this Agreement applicable to Authorized Third Parties. 9.6 Title and Authority. IGEN hereby represents and warrants to LLC that: (i) IGEN has the requisite corporate power and authority enter into this Agreement and to grant the license to LLC under Licensed ECL Technology hereunder and fully perform its obligations hereunder, and that the grant of rights and licenses, and the performance of its obligations hereunder, will not conflict with its charter documents or any agreement, contract or other arrangement to which it is a party or by which it is bound; (ii) IGEN has title to or license rights in the Licensed ECL Technology sufficient to grant such license rights to LLC and its Affiliates; (iii) IGEN has not assigned, transferred, licensed or otherwise disposed of Licensed ECL Technology in any manner that limits or restricts LLC's or its Affiliates' exploitation of the license granted by IGEN hereunder; and (iv) no consent, notice, approval, authorization, waiver or permit, to or from any person (other than the consent attached hereto), including, but not limited to, any Governmental Entity or third party holder of intellectual property rights is required to be obtained or made by IGEN in connection with its execution, delivery and performance of this Agreement. 9.7 Completeness of Exhibit A. IGEN hereby represents and warrants to LLC that Exhibit A includes all patents and patent applications which: (a) exist at or prior to the Effective Time; (b) are owned and/or controlled by IGEN and/or any Affiliate thereof; and (c) cover ECL Technology. If, after the Effective Time, it is discovered that IGEN has breached any of its representations and warranties under this Section 9.7 and additional patents or patent applications should have been or should be included in the patents and patent applications set forth in Exhibit A, then (i) such additional patent and patent applications shall be deemed automatically included in Exhibit A as of the Effective Time, without any amendment of this Agreement or other further action required of the Parties, and (ii) LLC shall hold a license to such additional patents and patent applications under and in accordance with the terms of this Agreement, as of the Effective Time. The foregoing shall be LLC's exclusive remedy for a breach by IGEN of the representations and warranties in this Section 9.7. 9.8 Indemnity. IGEN hereby agrees to indemnify and hold harmless LLC and its Affiliates (and their respective directors, officers, employees, consultants and agents and each of their heirs, executors, successors and assigns of the foregoing) (collectively the "Indemnitees") against all losses, claims, damages, liabilities, fees and expenses (including reasonable attorneys' fees), judgments, fines and amounts paid in settlement (in the case of settlements with the approval of LLC (which approval shall not be unreasonably withheld)) incurred by or imposed upon the Indemnitees (or any one of them) as a result of a breach by IGEN of any of IGEN's representations and warranties in Section 9.6; provided that LLC: (a) gives IGEN notice of such claim, (b) cooperates with IGEN, at A-10-14 IGEN's expense, in the defense of such claim, and (c) gives IGEN the right to control the defense and settlement of any such claim, except that IGEN shall not enter into any settlement that affects LLC's rights or interest without LLC's prior written approval. LLC shall have no authority to settle any claim on behalf of IGEN. 10. Disclaimer Of Warranties; Further Action. 10.1 Disclaimer. EXCEPT AS OTHERWISE PROVIDED HEREIN (E.G.

THE LIMITATION OF DAMAGES IN CLAUSE (B) ABOVE SHALL NOT APPLY TO DAMAGES PAID TO UNRELATED THIRD PARTIES (WHETHER PURSUANT TO JUDGMENT OR SETTLEMENT) FOR WHICH A PARTY HAS AN OBLIGATION TO INDEMNIFY THE OTHER PARTY HEREUNDER. 10.2 Export Control. LLC agrees, and shall cause its Affiliate Sublicensees to agree, to abide by all laws and regulations of the United States Government, or the government having jurisdiction therefor, governing the export or re-export of any Products.

Confidentiality. LLC and IGEN agree for themselves and their Affiliates, and on behalf of their respective officers, employees and agents, that until the later of (i) 10 years from the Effective Time hereof or (ii) 5 years after the termination date of this Agreement, each will treat as confidential, using the same degree of care as it uses for its own confidential and proprietary information, but in no event less than reasonable care, and shall not disclose to any third party, and shall not use for its own benefit or the benefit of any third party (except as permitted hereunder, including disclosures to Affiliates, permitted sublicensees or subcontractors to the extent necessary to have Products manufactured and subject to confidentiality obligations at least as restrictive as those contained herein) the Licensed ECL Technology (and any other information marked as confidential, and reports generated by the Field Monitor or accountant pursuant to Sections 2.5 and 5.1) furnished to it by the other party unless the furnishing party ("Discloser") otherwise agrees in writing or unless such information clearly and convincingly falls within the following exceptions: (a) Such confidential information was known to the receiving party ("Recipient") prior to the time of disclosure by the Discloser or was in the public domain at the time of disclosure by Discloser as can be documented by written records; or (b) Such confidential information is or becomes publicly known after disclosure by Discloser through no fault or omission attributable to Recipient; or (c) Such confidential information is given to Recipient from sources independent of Discloser who have the right to disclose it; or (d) Such confidential information is independently developed by employees of Recipient that did not have access to it as can be documented by written records; or (e) Recipient is required to disclose such confidential information to a court of law or to appropriate governmental agencies to enable Recipient to carry out the evaluation of a Product or to secure a governmental approval, or as otherwise required by law; provided, however, that (1) Recipient gives the Discloser prompt written notice of such required disclosure and reasonably assists the Discloser in its efforts to prevent or limit such disclosure; and (2) any confidential information disclosed pursuant to this Section 11(e) shall otherwise remain confidential information for the purposes of this Agreement. For purposes of this Agreement, IGEN's confidential information shall include (subject to the exclusions in (a)-(e) above) all information relating to ECL Technology or the Licensed ECL Technology whether such information is owned by IGEN or licensors of IGEN (other than Roche) and whether disclosed to ROCHE by IGEN or any licensor of IGEN (other than Roche) before or after the Effective Time. A-10-16 Furthermore, confidential information shall include all confidential information disclosed by IGEN to ROCHE or ROCHE to IGEN under the Prior Agreement or the Judgment (as defined in the Improvements License Agreement, dated as of the date hereof, by and between IGEN and ROCHE (the "Improvements License Agreement")). Access to such confidential information must be restricted to the Recipient's, sublicensee's, or subcontractor's employees or agents with a need to have access. The Recipient acknowledges that by virtue of this Agreement it acquires only such rights as set forth under the terms and conditions of this Agreement and only so long as it is in effect and does not acquire any rights of ownership or title in the Discloser's confidential information. In addition, each of the parties agrees to execute appropriate confidentiality agreements with third party collaborators of such party prior to disclosing the other party's confidential information to such third party collaborator. Upon termination or expiration of this Agreement, each party, its sublicensees, subcontractors and their employees and agents shall immediately discontinue use of the other's confidential information, except as otherwise permitted under the provisions hereof. The Parties agree that this Section 11 sets out in their entirety the Parties' confidentiality obligations with respect to the subject matter of this Agreement, and that this Section 11 shall supersede in its entirety as of the Effective Time all prior confidentiality agreements or arrangements with respect to the subject matter of this Agreement between or among the Parties and their Affiliates (including confidentiality agreements or arrangements between IGEN and Roche Diagnostics GmbH and its Affiliates). 12. License Registration. LLC shall pay all costs and legal fees connected with registration of this Agreement in those countries where it (or its Affiliate Sublicensees, Affiliates, distributors and/or agents) sells Products, where required, and shall otherwise ensure that the laws of all the countries where sales of its Products occur are fully satisfied. None of such amounts shall be deductible against amounts payable to IGEN hereunder. IGEN shall provide reasonable assistance to LLC in effecting such registrations if LLC reimburses any out-of-pocket expenses incurred in providing such assistance. 13. Interests in Intellectual Property Rights. 13.1 Preservation of Title. LLC acknowledges that IGEN shall retain full ownership and title to the intellectual property rights it licenses to LLC hereunder and that LLC has no rights in or to such intellectual property rights other than the express license rights specifically confirmed herein. Neither LLC nor any of LLC's employees, Affiliates or sublicensees, or any of their respective employees, have rights under this Agreement to practice or use the Licensed ECL Technology outside the Field. 13.2 Reservation of Rights. IGEN reserves the right to use for any purpose (commercial or noncommercial), anywhere in the world, and the right to allow other parties to use for any purpose, anywhere in the world, any Licensed ECL Technology licensed hereunder, without IGEN or such other parties being obligated to pay LLC any royalties or other compensation. 14. Miscellaneous. 14.1 Waiver. No delay or omission on the part of either Party to this Agreement in requiring performance by the other Party or in exercising any right hereunder shall operate as a waiver of any provision hereof or of any right or rights hereunder; and the waiver, omission or delay in requiring performance or exercising any right hereunder on any one occasion shall not be construed as a bar to or waiver of such performance or right, or of any right or remedy under this Agreement, on any future occasion. Any agreement on the part of either Party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. 14.2 Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their permitted successors and assigns; provided, however, that: (a) neither Party shall assign any of its rights and obligations hereunder except as consented to by the other Party, which consent shall not be unreasonably withheld, and (b) such consent shall not be required with respect to an assignment of (i) any or all of its rights and obligations hereunder to an Affiliate of such A-10-17 assigning Party; or (ii) all (but not less than all) of its rights and obligations hereunder to an acquirer of all or substantially all of the assets or business of the assigning party related to such Party's use of ECL Technology, whether as incident to a merger, consolidation, reorganization, acquisition or otherwise. In addition, IGEN may assign, without LLC's consent, all of its rights under this Agreement to IGEN Integrated Healthcare, LLC ("NEWCO") as a part of the transactions contemplated by the Merger Agreement. Whenever there has been an assignment or a sublicense by IGEN or LLC, as the case may be, as permitted by this Agreement, the term "IGEN" or "LLC" as used in this Agreement shall also include and refer to, if appropriate, such assignee or sublicensee. 14.3 Notices. Any notice or other communication required or permitted to be given to either Party hereto shall be in writing and shall be deemed to have been properly given and to be effective on the date of delivery if delivered in person or by facsimile (with electronic confirmation of receipt and with a confirmation copy sent by internationally-recognized air courier service), to such Party at the following address: In the case of IGEN: IGEN International, Inc. 16020 Industrial Drive Gaithersburg, Maryland 20877 United States of America Attention: President Fax No. (301) 208-3789 With a copy to IGEN's designated legal counsel.

Any delays in performance by any Party under this Agreement (other than a Party's failure to make payments hereunder) shall not be considered a breach of this Agreement if and to the extent caused by occurrences beyond the reasonable control of the Party affected, including but not limited to acts of God, embargoes, governmental restrictions, strikes or other concerted acts of workers, fire, flood, explosion, riots, wars, civil disorder, rebellion or sabotage. The Party suffering such occurrence shall immediately notify the other Party and any time for performance hereunder shall be extended by the actual time of delay caused by the occurrence. 14.6 Independent Contractors. In granting, performing or exercising rights under this Agreement, LLC and IGEN act and shall act at all times as independent contractors and nothing contained in this Agreement shall be construed or implied to create an agency, partnership or A-10-18 employer and employee relationship between IGEN and LLC. At no time shall one Party make commitments or incur any charges or expenses for or in the name of the other Party. 14.7 Severability. If, under applicable law, any term, condition or provision of this Agreement is invalid or unenforceable, or otherwise directly or indirectly affects the validity of any other material provision(s) of this Agreement (the "Severed Clause"), then this Agreement shall remain in full force and effect, except for the Severed Clause.

In the event that at any time during the Term of this Agreement a disagreement, dispute, controversy or claim should arise out of or relating to the interpretation of this Agreement, or performance by a Party under this Agreement, or a breach of this Agreement by a Party, or any claim by a Party that any provision of this Agreement is invalid (a "Dispute" or collectively "Disputes"), one Party shall give written notice to the other Party that a dispute exists and the Parties will then attempt in good faith to resolve their differences before resorting to arbitration provided in Section 6.2. If the Parties cannot resolve the disputed matter within thirty (30) days after such notice, then either Party shall be free to submit the disputed matter to binding arbitration in accordance with Section 6.2 hereof. For purposes of this Article 6, the terms "Party" and "Parties" shall include each of the signatories to this Agreement and/or any one or more of their respective Affiliates, whether the reference is to a Party as a claimant or a Party against which a claim is made. A-11-7 6.2 Arbitration. (a) The Parties intend Section 6.2 hereof to be enforceable in accordance with the Federal Arbitration Act (9 U.S.C. Section 1, et seq.), including any amendments to that Act which are subsequently adopted, notwithstanding any other choice of law provision set forth in this Agreement. In the event that either Party refuses to submit to arbitration as required herein, the other Party may request a United States District Court to compel arbitration in accordance with the Federal Arbitration Act. (b) Any dispute or other matter in question between LLC and IGEN arising out of or relating to the formation, interpretation, performance, or breach of this Agreement, whether such dispute or matter arises before or after termination of this Agreement, shall be resolved solely by arbitration if the Parties are unable to resolve the dispute through negotiation pursuant to Section 6.1 hereof. Arbitration shall be initiated by the delivery of a written notice of demand for arbitration by one Party to the other. The date on which the other Party receives such written notice shall be hereinafter referred to as the "Arbitration Notice Date." (c) Each Party shall appoint an individual as arbitrator and the two so appointed shall then appoint a third arbitrator. If either Party refuses or neglects to appoint an arbitrator within thirty (30) days after the Arbitration Notice Date, then the arbitration shall be conducted by a single arbitrator appointed by the American Arbitration Association. If two arbitrators are appointed but do not agree on the third arbitrator within sixty (60) days after the Arbitration Notice Date, each of the arbitrators shall nominate within sixty-seven (67) days after the Arbitration Notice Date three individuals. Each arbitrator shall then within seventy-two (72) days after the Arbitration Notice Date decline two of the nominations presented by the other arbitrator. The third arbitrator shall then be chosen from the remaining two nominations by drawing lots. Notwithstanding anything contained herein to the contrary, if the third arbitrator is not chosen with seventy-two (72) days after the Arbitration Notice Date, then the American Arbitration Association shall appoint the third arbitrator within seventy-seven (77) days after the Arbitration Notice Date. The arbitrators shall not be or have been affiliated with, or have any personal, financial or business relationship with, either of the Parties or any Affiliate of either Party; the arbitrators shall not have a personal or financial interest in the result of the arbitration. (d) The arbitration hearings shall be held in Borough of Manhattan, State of New York or such other place as may be mutually agreed by the Parties, shall be conducted in the English language and shall be conducted as confidential proceedings (except to the extent necessary to enforce the award resulting therefrom). Unless the Parties agree otherwise, the arbitrators shall commence the arbitration hearing within thirty (30) days after the selection of the third arbitrator. The arbitrators shall issue orders to protect the confidentiality of proprietary information, trade secrets and other sensitive information disclosed. Pending the arbitration hearing, at the request of a Party, the arbitrators may issue temporary injunctive or other equitable relief to address any violation or threatened violation of this Agreement. All awards shall be made based on a majority vote of the arbitrators, shall be in writing, shall not be considered confidential information of either Party, shall be issued within sixty (60) days after hearings before the arbitrators are completed, and shall state the reasoning on which the award rests unless the Parties agree otherwise. In addition to any relief at law which may be available to an aggrieved Party for such breach, such Party shall be entitled to injunctive and other equitable relief as the arbitration panel may grant. The arbitrators shall deliver a copy of the award to each Party personally or by registered mail. Any party may request within ten (10) days after receiving the decision that, for good cause, the arbitrators reconsider and modify such decision. The arbitrators shall have thirty (30) days after such request to modify their decision, if they consider it appropriate. Thereafter, the decision of the arbitrators shall be final, binding and nonappealable, except to the extent appeals are permitted by the Federal Arbitration Act, with respect to all persons, including (without limitation) persons who have failed or refused to A-11-8 participate in the arbitration process. Judgment upon the award rendered may be entered in any court having jurisdiction thereof. (e) Each Party shall bear its own costs in connection with any such arbitration including, without limitation, (i) all legal, accounting, and any other professional fees and expenses, (ii) the fees and expenses of its own arbitrator, and (iii) all other costs and expenses each Party incurs to prepare for such arbitration. Other than set forth above, each side shall pay, (iv) one-half of the fee and expenses of the third arbitrator, and (v) one-half of the other expenses that the Parties jointly incur directly related to the arbitration proceeding. (f) Except as provided above, arbitration shall be based upon the Commercial Arbitration Rules of the American Arbitration Association. Discovery shall be limited at the discretion of the arbitrators, so that the timing and extent of such discovery shall not interfere with the normal business operations of the Parties. The arbitrators may proceed to an award notwithstanding the failure of either Party to participate in the proceedings. (g) In the event of subsequent actions or proceedings to confirm the award or to enforce the judgment entered thereon or any other rights flowing therefrom, the prevailing Party shall be entitled to recover its reasonable attorney's fees incurred in such actions or proceedings. (h) The fact that the dispute resolution procedures specified in this Article 6 shall have been or may be invoked shall not excuse any Party from performing its obligations under this Agreement, and during the pendency of any such procedure the Parties shall continue to perform their respective obligations in good faith. 6.3 Limited Recourse to Courts. This Article 6 shall be the exclusive dispute resolution procedure for Disputes under this Agreement and no Party shall bring Disputes before any court, except as appeals to arbitration awards are permitted by Section 6.2. Except as permitted by Section 6.2, the Parties hereby waive any right to appeal an arbitration award to any court. The provisions of Section 6.2 may be enforced, and judgment on the award (including without limitation equitable remedies) granted in any arbitration hereunder may be entered, in any court of competent jurisdiction. The Parties hereby submit to the non-exclusive in personam jurisdiction of the federal courts in New York for such purposes. THE PARTIES HEREBY WAIVE ANY AND ALL RIGHTS TO TRIAL BY JURY FOR MATTERS RELATED TO DISPUTES SUBMITTED TO ANY COURT. 6.4 Governing Law.

IGEN and ROCHE agree and acknowledge that the patents, patent applications, information and consulting regarding the technology licensed hereunder heretofore delivered or provided to IGEN through the Effective Time satisfies ROCHE's obligations to deliver such material and provide such assistance as contemplated hereby or as required by the Judgment. IGEN and ROCHE further acknowledge that ROCHE has no other obligations to deliver such material or provide such assistance to IGEN. 8.3 Noninterference. In the event that any of the Improvements is subject to contractual restrictions by third parties that limit or prohibit IGEN from using such Improvements, ROCHE agrees not to interfere with, but shall have no affirmative obligation to assist in, IGEN's efforts to obtain a waiver of such contractual restrictions. Other than its seeking such waiver, IGEN shall not interfere with ROCHE's relationship/contractual arrangements with such third parties in IGEN's efforts to obtain such waiver. In addition, in the event that ROCHE or any of its Affiliates has an exclusive supplier or vendor, on IGEN's written request, ROCHE agrees to waive such exclusivity with respect to IGEN and its Affiliates for the commercialization of Products by IGEN and its Affiliates pursuant to this Agreement, but ROCHE shall not be required to waive such exclusivity with respect to other parties. The provisions of the foregoing sentence shall not apply to require ROCHE to waive its exclusive supply arrangement with Hitachi for ECL Instruments (as defined in the License Agreement). 9. Indemnification, Liability, Infringement. 9.1 Defense of Third Party Infringement Actions. If the manufacture, production, sale, or use of any Licensed Product results in a claim, suit or proceeding brought by a third party (each, an "Action") alleging patent infringement against ROCHE or IGEN (or any of their respective Affiliates), such Party shall promptly notify in writing the other Party. The Party subject to such Action (the "Controlling Party") shall have the exclusive right and obligation to defend and control the defense of any such Action using counsel of its own choice; provided that the Controlling Party shall not enter into any settlement of such Action without the written consent of the other Party, which consent may be withheld in the unfettered discretion of the other Party if such settlement admits the invalidity or unenforceability of any patent rights of the other Party, and otherwise may not be unreasonably withheld. The Controlling Party agrees to keep the other Party reasonably informed of all material developments in connection with any Action. 9.2 Suits for Infringement by Others. In the event either Party becomes aware of any actual or threatened infringement of any intellectual property rights licensed under this Agreement by any third party, that Party shall promptly notify the other Party, and the Parties shall discuss the most appropriate action to take. ROCHE shall have the sole right to bring, at its own expense, an infringement action against the third party infringer and shall be entitled to keep any awards made in such proceeding. IGEN may elect to appear as a Party to the suit and shall, at Roche's request, assist Roche without expense to Roche. 9.3 Product Liability Indemnity. IGEN expressly and unequivocally agrees to and hereby does indemnify, release, defend and hold ROCHE (and its Affiliates, sublicensees and licensors and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of the heirs, executors, successors and assigns of the foregoing) harmless from and against all claims, damages, losses, costs and expenses, including reasonable attorneys' fees, arising in favor of any person, firm or corporation resulting from or arising out of liability in any way relating to the Licensed Products sold, placed or otherwise commercialized by IGEN, or its Affiliates, Sublicensees or Authorized Third Parties, including without limitation, the manufacture, packaging, use, sale or other A-11-10 distribution of Licensed Products by IGEN or its Affiliates or sublicensees, or any representation made or warranty given by IGEN with respect to any Licensed Product provided that ROCHE (a) gives IGEN notice of such claim, (b) cooperates with IGEN, at IGEN's expense, in the defense of such claim, and (c) gives IGEN the right to control the defense and settlement of any such claim, except that IGEN shall not enter into any settlement that affects ROCHE's rights or interest without ROCHE's prior written approval. ROCHE shall have no authority to settle any claim on behalf of IGEN. IGEN also agrees to maintain proper product liability insurance policies, reasonably acceptable to ROCHE everywhere it sells Licensed Products and to furnish satisfactory evidence of same upon request by ROCHE from time to time. 9.4 Waiver of Claims. IGEN shall not assert, and IGEN shall ensure that its Affiliates and Sublicensees do not assert, any claims against ROCHE and its licensors (including ROCHE Licensors) for any matter for which IGEN has provided indemnity to ROCHE under Sections 9.3 and 9.5 hereof. IGEN shall indemnify, hold harmless and defend ROCHE and its licensors (including ROCHE Licensors) against any such claims. 9.5 Breach by Affiliate, Sublicensee or Authorized Third Party. Failure of an Affiliate, Sublicensee or Authorized Third Party to adopt and satisfy a condition stated in this Agreement applicable to IGEN, an Affiliate, Sublicensee or Authorized Third Party, as the case may be, shall be considered a breach of this Agreement by IGEN. IGEN and such Affiliate or Sublicensee shall be jointly and severally responsible for and indemnify ROCHE and its Affiliates (and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of the heirs, executors, successors and assigns of the foregoing) against any loss, cost, damage or liability (including reasonable attorneys' fees) arising from the breach by such Affiliate or Sublicensee of this Agreement. IGEN shall indemnify ROCHE and its Affiliates (and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of the heirs, executors, successors and assigns of the foregoing) against any loss, cost, damage or liability (including reasonable attorneys' fees) arising from the failure by an Authorized Third Party to adopt and satisfy a condition stated in this Agreement applicable to Authorized Third Parties. 9.6 Title and Authority. ROCHE hereby represents and warrants to IGEN that: (i) ROCHE has the requisite corporate power and authority to enter into this Agreement and to grant the license to IGEN under ROCHE Licensed Patent Rights, ROCHE Licensed Technology and Hitachi Intellectual Property Rights hereunder and fully perform its obligations hereunder, and that the grant of the rights and licenses, and the performance of its obligations hereunder, will not conflict with its charter documents or any agreement, contract or other arrangement to which it is a party or by which it is bound; (ii) ROCHE has title to or license rights in such licensed intellectual property rights sufficient to grant such license rights to IGEN and its Affiliates; (iii) ROCHE has not assigned, transferred, licensed or otherwise disposed of such licensed intellectual property rights in any manner that limits or restricts IGEN's or its Affiliates' exploitation of the license granted by ROCHE hereunder; (iv) no consent, notice, approval, authorization, waiver, or permit, to or from any person, including, but not limited to, any Governmental Entity or third party holder of intellectual property rights, is required to be obtained or made by ROCHE in connection with its execution, delivery and performance of this Agreement; and (v) Exhibit F includes all Hitachi patents and patent applications which ROCHE has the right to sublicense to IGEN, and that ROCHE has no other rights to Hitachi patents and patent applications which ROCHE has the right to sublicense to IGEN. 9.7 Completeness of Exhibit D. ROCHE hereby represents and warrants to IGEN that the Exhibit D includes all patents and patent applications which: (a) exist at or prior to the Effective Time; (b) are owned and/or controlled by ROCHE and/or any Affiliate thereof; and (c) satisfy the definition of ROCHE Improvements (other than PCR Technology or Hitachi Intellectual Property Rights). If, after the Effective Time, it is discovered that ROCHE has breached any of its representations and warranties under this Section 9.7 and additional patents or patent applications should have been or should be included in the patents and patent applications set forth in the A-11-11 Exhibit D, then (i) such additional patent and patent applications shall be deemed automatically included in Exhibit D, as of the Effective Time, without any amendment of this Agreement or other further action required of the Parties, and (ii) IGEN shall hold a license to such additional patents and patent applications under and in accordance with the terms of this Agreement, as of the Effective Time. The foregoing shall be IGEN's exclusive remedy for a breach by ROCHE of the representations and warranties in this Section 9.7. 9.8 Indemnity. ROCHE hereby agrees to indemnify and hold harmless IGEN, its Affiliates and any sublicensee (and their respective directors, officers, employees, consultants and agents and each of their heirs, executors, successors and assigns of the foregoing) (collectively the "Indemnitees") against all losses, claims, damages, liabilities, fees and expenses (including reasonable attorneys' fees), judgments, fines and amounts paid in settlement (in the case of settlements with the approval of IGEN (which approval shall not be unreasonably withheld)) incurred by or imposed upon the Indemnitees (or any one of them), as a result of a breach by ROCHE of any of ROCHE's representations and warranties in Section 9.6; provided, that IGEN: (a) gives ROCHE notice of such claim, (b) cooperates with ROCHE, at ROCHE's expense, in the defense of such claim, and (c) gives ROCHE the right to control the defense and settlement of any such claim, except that ROCHE shall not enter into any settlement that affects IGEN's rights or interest without IGEN's prior written approval. IGEN shall have no authority to settle any claim on behalf of ROCHE. 10. Disclaimer Of Warranties; Further Action. 10.1 Disclaimer. EXCEPT AS OTHERWISE PROVIDED HEREIN (E.G. SECTIONS 9.6, 9.7 and 9.8 REPRESENTATIONS, WARRANTIES AND INDEMNIFICATIONS) THE INTELLECTUAL PROPERTY RIGHTS LICENSED HEREUNDER ARE PROVIDED BY ROCHE "AS IS WHERE IS" AND ROCHE MAKES NO, AND DISCLAIMS ALL WARRANTIES AND REPRESENTATIONS, EXPRESS OR IMPLIED, CONCERNING: (a) LICENSED INTELLECTUAL PROPERTY RIGHTS COVERED BY THIS AGREEMENT, INCLUDING WITHOUT LIMITATION, ANY EXPRESS OR IMPLIED WARRANTY OF DESIGN, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE AS TO LICENSED INTELLECTUAL PROPERTY RIGHTS OR ANY PRODUCT; (b) THE COMMERCIAL SUCCESS OF ANY PRODUCT; (c) THE EXISTENCE, VALIDITY OR SCOPE OF LICENSED INTELLECTUAL PROPERTY RIGHTS; (d) ANY PRODUCT BEING FREE FROM AN INFRINGEMENT ON PATENTS OR OTHER INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES; (e) WHETHER ANY THIRD PARTIES ARE IN ANY WAY INFRINGING LICENSED INTELLECTUAL PROPERTY RIGHTS COVERED BY THIS AGREEMENT; OR (f) THE ACCURACY, UTILITY OR SUFFICIENCY OF ANY TECHNICAL INFORMATION TRANSFERRED TO IGEN HEREUNDER.

THE LIMITATION OF DAMAGES IN CLAUSE (B) ABOVE SHALL NOT APPLY TO DAMAGES PAID TO UNRELATED THIRD PARTIES (WHETHER PURSUANT TO JUDGMENT OR SETTLEMENT) FOR WHICH A PARTY HAS AN OBLIGATION TO INDEMNIFY THE OTHER PARTY HEREUNDER. 10.2 Export Control. IGEN agrees, and shall cause its Affiliates and Sublicensees to agree, to abide by all laws and regulations of the United States Government, or the government having A-11-12 jurisdiction therefor, governing the export or re-export of any Licensed Products.

Confidentiality. ROCHE and IGEN agree for themselves and their Affiliates, and on behalf of their respective officers, employees and agents, that until the later of (i) 10 years from the Effective Time hereof or (ii) 5 years after the expiration date of this Agreement (in perpetuity as to confidential and A-11-13 proprietary information of Hitachi, or such shorter period as Hitachi agrees with IGEN in writing or to which ROCHE is subject), each will treat as confidential, using the same degree of care as it uses for its own confidential and proprietary information, but in no event less than reasonable care, and shall not disclose to any third party, and shall not use for its own benefit or the benefit of any third party (except as permitted hereunder, including disclosures to IGEN Affiliates and permitted sublicensees or subcontractors to the extent necessary to have Products manufactured and subject to confidentiality obligations at least as restrictive as those contained herein) the ROCHE Licensed Patent Rights, ROCHE Licensed Technology or Hitachi Intellectual Property Rights (and any other information marked as confidential, and reports generated by the Field Monitor or accountant pursuant to Sections 2.6 and 5.1) furnished to it by the other Party unless the furnishing party ("Discloser") otherwise agrees in writing or unless such information clearly and convincingly falls within the following exceptions: (a) Such confidential information was known to the receiving party ("Recipient") prior to the time of disclosure by the Discloser or was in the public domain at the time of disclosure by Discloser as can be documented by written records; or (b) Such confidential information is or becomes publicly known after disclosure by Discloser through no fault or omission attributable to Recipient; or (c) Such confidential information is given to Recipient from sources independent of Discloser who have the right to disclose it; or (d) Such confidential information is independently developed by employees of Recipient that did not have access to it as can be documented by written records; or (e) Recipient is required to disclose such confidential information to a court of law or to appropriate governmental agencies to enable Recipient to carry out the evaluation of a Product or to secure a governmental approval, or as otherwise required by law; provided, however, that (1) Recipient gives the Discloser prompt written notice of such required disclosure and reasonably assists the Discloser in its efforts to prevent or limit such disclosure; and (2) any confidential information disclosed pursuant to this Section 11(e) shall otherwise remain confidential information for the purposes of this Agreement. For purposes of this License, ROCHE's confidential information shall include (subject to the exclusions in (a)-(e) above) all information relating to the ROCHE Licensed Patent Rights, ROCHE Licensed Technology and Hitachi Intellectual Property Rights whether such information is owned by ROCHE or ROCHE Licensors and whether disclosed to IGEN by ROCHE or any ROCHE Licensor before or after the Effective Time. Furthermore, each Party's confidential information hereunder shall include all confidential information of such Party disclosed to the other Party under the Prior Agreement or the Judgment. Access to such confidential information must be restricted to the Recipient's, sublicensee's, or subcontractor's employees or agents with a need to have access. The Recipient acknowledges that by virtue of this Agreement it acquires only such rights as set forth under the terms and conditions of this Agreement and only so long as it is in effect and does not acquire any rights of ownership or title in the Discloser's confidential information. In addition, each of the Parties agrees to execute appropriate confidentiality agreements with third party collaborators of such Party prior to disclosing the other party's confidential information to such third party collaborator. Upon expiration of this Agreement, each Party, its sublicensees, subcontractors and their employees and agents shall immediately discontinue use of the other's confidential information, except as otherwise permitted under the provisions hereof. The Parties agree that this Section 11 sets out in its entirety the Parties' confidentiality obligations with respect to the subject matter of this Agreement, and that this Section 11 shall supercede in its entirety as of the Effective Time all prior confidentiality agreements or arrangements with respect to the subject matter of this Agreement between or among the Parties and their Affiliates (including confidentiality agreements or arrangements between IGEN and Roche Diagnostics GmbH and its Affiliates). A-11-14 12. License Registration. IGEN shall pay all costs and legal fees connected with registration of this Agreement in those countries where it (or its Affiliates, Sublicensees, distributors and/or agents) sells Licensed Products, where required, and shall otherwise ensure that the laws of all the countries where sales of its Licensed Products occur are fully satisfied. None of such amounts shall be deductible against amounts payable to ROCHE hereunder. ROCHE shall provide reasonable assistance to IGEN in effecting such registrations if IGEN reimburses any out-of-pocket expenses incurred in providing such assistance. 13. Interests in Intellectual Property Rights. 13.1 Preservation of Title. IGEN acknowledges that ROCHE, its Affiliates and ROCHE Licensors, where applicable, shall retain full ownership and title to the intellectual property rights it licenses to IGEN hereunder and that IGEN has no rights in or to such intellectual property rights other than the express license rights specifically confirmed herein. Neither IGEN nor any of IGEN's employees, Affiliates and Sublicensees, or any of their respective employees, have rights under this Agreement to practice or use the ROCHE Licensed Patent Rights, ROCHE Licensed Technology or Hitachi Intellectual Property Rights to develop, manufacture, sell or otherwise commercialize products not based on the ECL Technology or, with respect to the Hitachi Intellectual Property Rights, to copy, make, have made, use and/or sell Products in the Field. 13.2 Hitachi Interest. Hitachi, as subcontractor for ROCHE, owns the Hitachi Intellectual Property Rights that have been licensed to ROCHE for sublicense to IGEN. 13.3 Reservation of Rights. ROCHE reserves the right to use for any purpose (commercial or noncommercial), anywhere in the world, and the right to allow other parties to use for any purpose, anywhere in the world, any ROCHE Licensed Patent Rights and ROCHE Licensed Technology licensed hereunder, without ROCHE or such other parties being obligated to pay IGEN any royalties or other compensation. Without limiting the generality of the foregoing, ROCHE reserves the right to license any Party to use the ROCHE Improvements in non-ECL Technology applications and in any fields, including without limitation all fields outside the Field. 14. Miscellaneous. 14.1 Waiver. No delay or omission on the part of either Party to this Agreement in requiring performance by the other Party or in exercising any right hereunder shall operate as a waiver of any provision hereof or of any right or rights hereunder; and the waiver, omission or delay in requiring performance or exercising any right hereunder on any one occasion shall not be construed as a bar to or waiver of such performance or right, or of any right or remedy under this Agreement, on any future occasion. Any agreement on the part of either Party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. 14.2 Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their permitted successors and assigns; provided, however, that: (a) neither Party shall assign any of its rights and obligations hereunder except as consented to by the other Party, which consent shall not be unreasonably withheld, and (b) such consent shall not be required with respect to an assignment of (i) any or all of its rights and obligations hereunder to an Affiliate of such assigning party; or (ii) all (but not less than all) of its rights and obligations hereunder to an acquirer of all or substantially all of the assets or business of the assigning party related to such party's use of ECL Technology, whether as incident to a merger, consolidation, reorganization, acquisition or otherwise. In addition, IGEN may assign, without Roche's consent, all of its rights under this Agreement to IGEN Integrated Healthcare, LLC ("NEWCO") as a part of the transactions contemplated by the Merger Agreement. Whenever there has been an assignment or a sublicense by IGEN or ROCHE, as the case may be, as permitted by this Agreement, the term "IGEN" or "ROCHE" as used in this Agreement shall also include and refer to, if appropriate, such assignee or sublicensee. 14.3 Notices. Any notice or other communication required or permitted to be given to either Party hereto shall be in writing and shall be deemed to have been properly given and to be effective A-11-15 on the date of delivery if delivered in person or by facsimile (with electronic confirmation of receipt and with a confirmation copy sent by internationally-recognized air courier service), to such Party at the following address: In the case of IGEN: IGEN International, Inc. 16020 Industrial Drive Gaithersburg, Maryland 20877 United States of America Attention: President Fax No.: 1-301-208-3789 With a copy to IGEN's designated legal counsel.

The Party suffering such occurrence shall immediately notify the other Party and any time for performance hereunder shall be extended by the actual time of delay caused by the occurrence. 14.6 Independent Contractors. In granting, performing or exercising rights under this Agreement, ROCHE and IGEN act and shall act at all times as independent contractors and nothing contained in this Agreement shall be construed or implied to create an agency, partnership or employer and employee relationship between IGEN and ROCHE. At no time shall one Party make commitments or incur any charges or expenses for or in the name of the other Party. 14.7 Severability. If, under applicable law, any term, condition or provision of this Agreement is held invalid or unenforceable, or otherwise directly or indirectly affects the validity of any other material provision(s) of this Agreement (the "Severed Clause"), then this Agreement shall remain in full force and effect, except for the Severed Clause.

The following examples are presented for clarification of the procedure to be followed in determining the royalties due for Licensed Tests, where Licensed PCR Tests or Licensed Expanded PCR Tests, performed internally by IGEN or its Affiliates, for both initial screening of pools and reflux testing necessary to detect the positive sample(s) in a pool identified as a true positive. a) Licensed Tests performed for initial screening: Number of pools multiplied by the number of analytes tested for multiplied by the fixed royalty rate for a Licensed Expanded PCR Test (e.g., 700 pools X 3 (HCV, HIV, HBV) X $25 = $52,500) b) Licensed Tests performed for reflux testing: Number of true positive samples multiplied by the number of reflux tests performed to identify each positive sample. For example, in a pool size of 600 which is subdivided in 6 pools with 100 samples each, the following would apply: The 6 pools of 100 are each tested (6 tests). The individual members of these 6 pools are arranged in a 10x10 matrix (10 rows with 10 individual samples in each row and 10 columns with 10 individual samples in each column). Each row is pooled as a pool of 10. Each column is pooled as a pool of ten. These 20 pools of ten are then tested to identify the positive member by row and column (20 tests). Thus, in order to detect a positive plasma, 26 Licensed Test would have to be processed. In the event that 15 true positive plasmas were identified by Licensed Expanded PCR Tests the royalty would be calculated as 15 X 26 X $25 = $9,750). Reference or control PCR tests carried on in connection with testing of a Test Sample shall be royalty free. If a new chemical or a new lot of chemical is introduced into the testing which make control tests necessary, such tests shall be royalty free. 4.5C Royalties Due to Roche for products Sold in the DNA Manufacturing Field. IGEN shall account to and pay to Roche/USA for each Royalty Payment Period during the term of this Agreement a royalty equal to the percentages listed below, of the Net Sales of Licensed Products that are (i) in the DNA Manufacturing Field, (ii) Sold in any country or territory of the world, and (iii) at the time of such Sale covered by, or the use thereof is covered by, one or more Valid Claims of Licensed Patents in the country of sale: (a) for direct Sales of such Licensed Products to end users, earned royalties equal to three percent (3%) of such Net Sales; and (b) for Sales of such Licensed Products to distributors, earned royalties equal to five percent (5%) of such Net Sales. A-13-12 4.5D Royalties Due to Roche for products Sold in the HLA Typing Field. IGEN shall account to and pay to Roche/Basel for each Royalty Payment Period during the term of this Agreement a royalty equal to the percentages listed below, of the Net Sales of Licensed Products that are (i) in the HLA Typing Field, (ii) Sold in any country or territory of the world, and (iii) at the time of such Sale covered by, or the use thereof is covered by, one or more Valid Claims of Licensed Patents in the country of sale: (a) a royalty of twenty percent (20%) on Net Sales of such Licensed Products; provided, however, that such royalty rate shall apply only for so long as any claim of U.S. Patent Nos. 4,683,195 or 4,683,202 (if Sold in the United States), or any claim of corresponding foreign patent rights in the country of Sale, shall be in force. Thereafter, the Parties shall negotiate in good faith a reduced royalty rate for such Licensed Products licensed hereunder. 4.6 Reporting and Payment. (a) With respect to the royalties required pursuant to Section 4.2, 4.3 and 4.4 and 4.5D, IGEN shall, within sixty (60) days after the close of each Royalty Reporting Period, provide to: KPMG Fides Peat Steinengraben 5 CH-4003 Basel, Switzerland To the attention of: Licensing Trustee Fax: +41 61 286-9401 or another trustee as notified to IGEN by Roche, an account of all Net Sales of such Royalty Products outside the United States and within the United States and of the royalty due pursuant to Section 4.2, 4.3 and 4.4 and 4.5D in respect to the preceding Royalty Reporting Period, according to the royalty report forms in Exhibit "2". Simultaneously, when it delivers such account, IGEN shall make payment of the royalty amount shown, as follows: Credit Suisse, Basel Switzerland Account No. 0504/920 654/62-1 SWIFT Code: CRESCHZZ40R To the account of: KPMG Fides Peat With the reference: DI-PC1-9962 Each royalty report of IGEN will be released by KPMG Fides Peat to Roche after one (1) calendar year following the subject Royalty Reporting Period. (b) The royalties payable by IGEN in US Dollars to Roche on the Net Sales outside of the United States of all Royalty Products by the IGEN Sellers in the Licensed Fields shall be converted by IGEN from the currency in which the Sales were made to US Dollars converted using the method used by IGEN for internal financial reporting purposes in accordance with United States generally accepted accounting principles. (c) With respect to the royalties required pursuant to Section 4.5, 4.5B or 4.5C, IGEN shall, within sixty (60) days after the close of each Royalty Reporting Period provide to: Roche Molecular Systems, Inc. 1145 Atlantic Avenue Alameda, CA 94501 Attention: Licensing Department an account, on a U.S./ex-U.S. basis, of all Net Sales of such Royalty Products Sold and of the royalty due pursuant to Section 4.5, 4.5B or 4.5C in respect to the Royalty Reporting Period, according to the royalty report forms in Exhibit "3". Simultaneously, when it delivers such A-13-13 account, IGEN shall make payment of the royalty due in US Dollars by wire transferred to the bank account as shown below: Roche Molecular Systems, Inc. Chase Manhatten Bank of New York ABA No.: 02000021 Account No.: 323839657 4.7 Withholding. (a) Any withholding tax levied by a government, in the country where payment originates, on payments made by IGEN to Roche shall be borne by Roche. IGEN shall use commercially reasonable efforts to do all things necessary to enable Roche to claim exemption therefrom under any double taxation or similar agreement in force and shall produce to Roche proper evidence of payment of all withholding tax and other certification that might be required by the respective double taxation agreement. (b) In case any taxing authority holds: (i) that any payment from any Affiliate of IGEN to IGEN is in effect a royalty payment from such Affiliate of IGEN to Roche, and (ii) such royalty payment to Roche is subject to a withholding tax, then, at such time, the Parties will discuss the issue and try to find an appropriate solution satisfying the business interests of both Parties. (c) Except as otherwise provided in subsections (a) and (b) above, all payments of royalties and other consideration made by IGEN to Roche under this Agreement shall be made in full without deduction of taxes, charges and any other duties that may be imposed on such payments to Roche. 4.8 Books and Records. (a) IGEN shall keep a complete and accurate set of books and records relating to the quantity of Royalty Products shipped by or for IGEN and its Affiliates and the Sales of Royalty Products by IGEN and its Affiliates. Such books and records shall contain sufficient detail to substantiate the computation of the Net Sales of Royalty Products and the amount of royalties payable under this Article 4 as well as all other information in the statements of account provided for in Section 4.7 above, and shall be maintained by IGEN for a period of not less than three (3) years from the date of such Sales. (b) Roche shall be entitled, upon reasonable notice to IGEN, to have such books and records audited by an independent certified public accounting firm retained by Roche and reasonably acceptable to IGEN (which acceptance shall not be unreasonably withheld), provided that any such audit occurs during IGEN's normal business hours not more than once in any calendar year. Roche also shall be entitled to have copies of the books and records of each of IGEN's Affiliates relating to the quantity of Royalty Products shipped by or for such Affiliate and such Affiliate's Sales of Royalty Products audited, upon reasonable notice to such Affiliate, by an independent certified public accounting firm retained by Roche and reasonably acceptable to such Affiliate, provided that any such audit occurs during such Affiliate's normal business hours not more than once in any calendar year. Roche agrees that all audited information shall be confidential to IGEN and IGEN's Affiliates. Any such audit will be limited to those records required to be maintained pursuant to Section 4.8(a) and the Sales associated therewith. (c) Any person conducting an audit on behalf of Roche will be required to protect the confidentiality of such information and shall provide to Roche a report only of the ultimate conclusions resulting from such audit. Except where IGEN disputes the conclusion of the audit by written notice to Roche, IGEN shall pay promptly to Roche the amount of any royalties determined by such an audit to be outstanding, along with interest accrued up to and including the date of payment as provided in Section 4.9 below. The costs of such an audit shall be borne by Roche; provided, however, that, if such audit determines that the royalties paid by IGEN for any audited Royalty Payment Period were at least five percent (5%) less than the royalties otherwise due and A-13-14 payable, then IGEN shall reimburse Roche for the costs of such audit. If such audit determines that IGEN has overpaid the amount of royalties otherwise due and payable for the audited Royalty Payment Period, then Roche shall credit the amount of such overpayment, plus interest at the rate provided in Section 4.9, to IGEN against future royalties payable by IGEN. 4.9 Past Due Payments. If IGEN fails to pay any amount specified under this Agreement after the due date thereof, the amount owed shall bear an interest of one percent (1%) per month from the due date until paid, provided, however, that if this interest rate is held to be unenforceable for any reason, the interest rate shall be the maximum rate allowed by law at the time the payment is made. 4.10 No Multiple Royalties. At no time shall more than one royalty be payable by IGEN upon the Net Sales of any one Royalty Product, regardless of whether the manufacture, use and/or Sale of such Royalty Product would infringe more than one Valid Claim of one or more Licensed Patents and regardless of whether such product qualifies as a "Royalty Product" for purposes of this Agreement under more than one of the criteria for designating a product to be a "Royalty Product" as provided in Section 1.31 above. 4.11 Most Favored Licensee. (a) If, after the Effective Time, Roche grants to any Third Party a license in the In Vitro Human Diagnostics Field under substantially equivalent terms and conditions as granted to IGEN herein but under more favorable royalty rates than those given to IGEN under this Agreement, Roche shall promptly notify IGEN of such more favorable royalty rates, and IGEN shall have the right and option to substitute such more favorable royalty rates for the royalty rates contained herein. (b) IGEN's right to elect such more favorable royalty rates shall extend only for so long as and shall be conditioned on IGEN's acceptance of all the same conditions, favorable or unfavorable, under which such more favorable royalty rates shall be available to such Third Party including any increase in license fees and the application of milestones payments, if any. Upon IGEN's acceptance of all such terms of such Third Party agreement, the more favorable royalty rates shall be effective as to IGEN on the effective date of such Third Party agreement. (c) Notwithstanding the foregoing, in the event that Roche shall receive substantial nonmonetary consideration in the form of technology or intellectual property rights to technology, as a part of the consideration for its granting such a license to a Third Party, then this Section 4.11 shall not apply. (d) It is understood by the Parties that a trustee has been appointed by Roche, who will be managing certain of the royalty reporting and royalty payments from IGEN to Roche under this Agreement as described in Sections 4.2, 4.3 and 4.4. IGEN is entitled to contact the trustee should IGEN wish to review compliance by Roche with this Section 4.11. At present, KPMG Fides Peat, Basel, Switzerland is the said trustee. Roche shall promptly provide written notice to IGEN of any change in trustee.

ARTICLE 6 THIRD PARTY CLAIMS; LIMITATION ON LIABILITY; INDEMNIFICATION 6.1 Defense of Third Party Infringement Actions. If the manufacture, production, sale, or use of any Licensed Product results in a claim, suit or proceeding brought by a Third Party (each, an "Action") alleging patent infringement against ROCHE or IGEN (or any of their respective Affiliates), such Party shall promptly notify in writing the other Party. The Party subject to such Action (the "Controlling Party") shall have the exclusive right and obligation to defend and control the defense of any such Action using counsel of its own choice; provided that the Controlling Party shall not enter into any settlement of such Action without the written consent of the other Party, which consent may be withheld in the unfettered discretion of the other Party if such settlement admits the invalidity or unenforceability of any patent rights of the other Party, and otherwise may not be unreasonably withheld. The Controlling Party agrees to keep the other Party reasonably informed of all material developments in connection with any Action. 6.2 Product Liability Indemnity. IGEN expressly and unequivocally agrees to and hereby does indemnify, release, defend and hold ROCHE (and its Affiliates, sublicensees and licensors and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of A-13-17 the heirs, executors, successors and assigns of the foregoing) harmless from and against all claims, damages, losses, costs and expenses, including reasonable attorneys' fees, arising in favor of any person, resulting from or arising out of liability in any way relating to the Licensed Products sold, placed or otherwise commercialized by IGEN, or its Affiliates, Distributors, or Authorized Third Parties, including without limitation, the manufacture, packaging, use, sale or other distribution of Licensed Products by IGEN or its Affiliates, or any representation made or warranty given by IGEN of any of its Affiliates with respect to any Licensed Product provided that ROCHE (a) gives IGEN notice of such claim, (b) cooperates with IGEN, at IGEN's expense, in the defense of such claim, and (c) gives IGEN the right to control the defense and settlement of any such claim, except that IGEN shall not enter into any settlement that affects ROCHE's rights or interest without ROCHE's prior written approval. ROCHE shall have no authority to settle any claim on behalf of IGEN. IGEN also agrees to maintain proper product liability insurance policies, reasonably acceptable to ROCHE everywhere it sells Licensed Products and to furnish satisfactory evidence of same upon request by ROCHE from time to time. 6.3 Waiver of Claims. IGEN shall not assert, and IGEN shall ensure that its Affiliates do not assert, any claims against ROCHE for any matter for which IGEN has provided indemnity to ROCHE under Sections 6.2 and 6.4 hereof. IGEN shall indemnify, hold harmless and defend ROCHE against any such claims. 6.4 Breach by Affiliate, Authorized Third Party or Research Collaborator. Failure of an Affiliate, Authorized Third Party or Research Collaborator to adopt and satisfy a condition stated in this Agreement applicable to IGEN, an Affiliate, Authorized Third Party or Research Collaborator, as the case may be, shall be considered a breach of this Agreement by IGEN. IGEN and such Affiliate shall be jointly and severally responsible for and indemnify ROCHE and its Affiliates (and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of the heirs, executors, successors and assigns of the foregoing) against any loss, cost, damage or liability (including reasonable attorneys' fees) arising from the breach by such Affiliate of this Agreement. IGEN shall indemnify ROCHE and its Affiliates (and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of the heirs, executors, successors and assigns of the foregoing) against any loss, cost, damage or liability (including reasonable attorneys' fees) arising from the failure by an Authorized Third Party or Research Collaborator to adopt and satisfy a condition stated in this Agreement applicable to such parties. ARTICLE 7 PATENT ENFORCEMENT 7.1 Notice of Substantial Infringement. In the event IGEN becomes aware of an alleged Substantial Infringement of a Licensed Patent in a given country by an unlicensed Third Party, IGEN may invoke the provisions of this Article 7 as to enforcement and royalty abatement by providing written notice thereof to Roche, including documentary evidence of Infringement and market data as to the infringing Sales activity which are in Roche's good faith judgment reasonably reliable. "SUBSTANTIAL INFRINGEMENT" or "SUBSTANTIALLY INFRINGING" as used in this Article 7 shall mean that the alleged infringing Sales of the Third Party in the given country are at least fifteen percent (15%) of total Sales of Competing Products in such country. "COMPETING PRODUCTS" means all products essentially equivalent to a Complete Diagnostic Kit and which test for the same analytes and which directly compete with each other for use in or in conjunction with PCR (for example, a test for the presence of an organism would not be considered to be testing for the same analyte as a test for a specific drug resistant subspecies of such organism, but two PCR-based tests both of which detect the presence of HIV1 (even if using different sequences of the genome) would be considered to be testing for the same analyte whereas two tests, one for HIV1 and one for HIV2, would be considered to be testing for different analytes). 7.2 Enforcement and Royalty Abatements. If Roche fails, within sixty (60) days of such notice of Substantial Infringement of a Licensed Patent by a Third Party in a given country, to enter into license negotiations with or enforcement proceedings against such Third Party in such country, or if having timely A-13-18 entered into license negotiations with such Third Party, Roche fails to obtain an executed license agreement or enter into enforcement proceedings with such Third Party within six (6) months of said notice, then IGEN shall be entitled to a fifty percent (50%) reduction in royalties on IGEN's Net Sales of Royalty Products which are Competing Products with such Substantially Infringing Sales in such country as of such notice, continuing until Roche provides written notice to IGEN that either a license has been granted to such Third Party or enforcement proceedings have been brought against such Third Party. In the event the Substantially Infringing Sales shall exceed thirty percent (30%) of total competing Sales in any particular Royalty Payment Period, then the royalty reduction shall be one hundred percent (100%) for such Royalty Payment Period. An enforcement proceeding shall mean a court action or other legal action brought before a competent patent authority in the relevant country. An enforcement proceeding pursued against such infringer for Sales of such infringing product in one Major Territory shall satisfy Roche's obligation to pursue enforcement hereunder against such products in all countries. If no Substantial Infringement exists in any such Major Territory, then a suit in any other country where such Substantial Infringement exists shall satisfy Roche's obligation hereunder. "MAJOR TERRITORY" shall mean any of the United States, Great Britain, Germany, France, Italy, The Netherlands and Japan. 7.3 Continuing Royalty Payment Obligations. Except to the extent provided in Section 7.2, IGEN's obligation to pay royalties on the Net Sales of Royalty Products Sold by the IGEN Sellers shall remain in effect to the extent provided for in this Agreement notwithstanding any alleged infringement by any Third Party of any of the Licensed Patents. 7.4 No IGEN Right to Enforce the Licensed Patents. It is expressly understood that nothing contained herein shall in any way grant or be construed to grant to IGEN the right to enforce the Licensed Patents. Roche shall have the sole right to bring legal action to enforce the Licensed Patents against any alleged Infringement by any Third Party. ARTICLE 8 TERM AND TERMINATION 8.1 Term. The term of this Agreement shall commence as of the Effective Time and shall continue in full force and effect, unless terminated sooner in accordance with Section 8.2 below, until the expiration date of the last to expire of the Valid Claims of the Licensed Patents. 8.2 Termination. This Agreement, and the licenses granted to IGEN and its Affiliates herein, are perpetual and irrevocable, except to the extent termination is permitted in this Section 8.2: (a) IGEN may terminate this Agreement with respect to all or any one or more of the Licensed Patents for any reason by written notice to Roche at any time during the term of this Agreement. (b) Roche may terminate this Agreement immediately upon written notice to IGEN if IGEN fails to make the payments in accordance with Section 4.1. (c) In the event that IGEN does not make any royalty payments which are due and payable (other than under Section 4.1), Roche may deliver written notice thereof to IGEN. If IGEN, within sixty (60) days after delivery of such notice to IGEN (the "Notice Period"), makes such payment to Roche, then Roche shall not have the right to terminate this Agreement for such non-payment. If, at the expiration of the Notice Period, IGEN has neither paid such royalty payment to Roche nor disputed the payment obligation in a written notice to Roche, then Roche may, upon written notice to IGEN following the Notice Period, terminate this Agreement. If, during the Notice Period, IGEN provides written notice to Roche that IGEN disputes such payment obligation, then the Parties shall arbitrate such dispute in accordance with Section 11.2. If the arbitration award requires IGEN to pay all or any portion of such royalty payments to Roche (the "Arbitrated Amount"), then IGEN shall pay such Arbitrated Amount to Roche within thirty (30) days after final resolution of the dispute or, if IGEN fails to do so, Roche may, upon written notice to IGEN following such 30-day period, terminate this Agreement. If the arbitration award does not require IGEN to pay any portion of such A-13-19 royalty payments to Roche, then Roche shall not have the right to terminate this Agreement with respect to such claimed non-payment. (d) Bankruptcy. IGEN shall retain the rights granted to it as a licensee under Section 365(n) of the United States Bankruptcy Code in case of the bankruptcy, insolvency or winding-up of ROCHE. (e) Expiration or termination of this Agreement shall not affect the ability of any Party to seek resolution of any matter arising prior to such expiration or termination pursuant to Article 11 herein. (f) The Parties agree that the provisions of this Section 8.2 shall not be considered when making the determination pursuant to Section 4.11(a), nor amended in the event of exercise of Section 4.11(b). (g) In the event of the termination of any license, in whole or in part, under this Agreement, the manufacture and/or Sale by the IGEN Sellers of products covered by such license shall cease immediately to the extent that such manufacture and/or Sale no longer is licensed as a result of such termination, except that such products in inventory as of the date of such termination may be Sold in accordance with the terms and subject to the restrictions of this Agreement for a period of one hundred eighty (180) days following such termination and royalties shall be due and payable on the Net Sales of such products in accordance with the terms of this Agreement. 8.3 Survival of Certain Rights Upon Expiration or Termination. All rights granted to and obligations undertaken by the Parties hereunder shall terminate immediately upon the expiration of the term of this Agreement (as set forth in Section 8.1 above) or the termination of this Agreement (pursuant to Section 8.2 above) except for: (a) The obligations of IGEN to pay any and all royalties or other consideration accrued hereunder prior to such expiration or termination (or during the one hundred eighty (180) day period following termination in the case of inventory as of the date of termination); (b) The right of Roche to have audited by an independent certified public accounting firm the books and records of IGEN and IGEN's Affiliates as provided in Section 4.8 above; (c) The indemnification provisions of Section 6.2 above; (d) The procedures set forth in Article 11 herein in respect of any matter arising prior to such expiration or termination; and (e) Any and all confidentiality obligations provided for in this Agreement; and (f) Sections 4.9, 8.2(e), 8.2(g), 8.3, 10, 12.1, 12.3, 12.5, 12.8, 12.9, 12.10, 12.14, 12.15, 12.17, 12.18 and 12.20. ARTICLE 9 ADDITIONAL COVENANTS AND AGREEMENTS 9.1 IGEN shall not, and shall cause each of its Affiliates not to, enter into a joint venture or other arrangement with any Third Party that would result in the conveyance to such Third Party of benefits substantially equivalent to those that would be received from a sublicense under the Licensed Patents licensed under this Agreement. Nothing in the foregoing shall restrict or limit IGEN's rights to sublicense, assign or transfer its rights hereunder in accordance with Sections 2.1, 2.3(e), 2.4 or 12.9. 9.2 IGEN shall not, and shall cause each of its Affiliates not to, arrange Sales of Royalty Products (or utilize the definitions relating thereto) to reduce in bad faith the Net Sales for which royalties are payable by IGEN hereunder. 9.3 IGEN shall not tolerate and shall enforce the provisions of any contract with a Research Collaborator of IGEN in the event that such Research Collaborator of IGEN repeatedly and materially A-13-20 fails to adhere to the provisions of its contract with IGEN and/or any of its Affiliates requiring that Licensed Products necessary to perform the work under such contract may be used only for the purposes of the protocol and that any Licensed Products not consumed in performing the work under such contract either be returned to IGEN and its Affiliates or be disposed of as laboratory waste. ARTICLE 10 REPRESENTATIONS AND WARRANTIES 10.1 Representations and Warranties of IGEN. IGEN hereby represents and warrants to Roche as follows: (a) The execution, delivery and performance of, and the consummation by IGEN of the transactions contemplated by, this Agreement have been duly authorized by all necessary action on the part of IGEN and no further consents by IGEN are needed in order to consummate the transactions contemplated hereby.

(c) IGEN's execution of this Agreement shall not constitute a breach or default under any contract, instrument or agreement to which IGEN or any of its Affiliates is a Party or by which IGEN or any of its Affiliates is bound. (d) All persons who will execute this Agreement on behalf of IGEN have been duly authorized to do so by all necessary action on the part of IGEN. 10.2 Representations and Warranties of Roche. Roche hereby represents and warrants to IGEN as follows: (a) Roche/Basle has the full power and right to grant to IGEN and IGEN's Affiliates the license outside of the United States under the Licensed Patents, and Roche/USA has the full power and right to grant to IGEN and IGEN's Affiliates the license in the United States under the Licensed Patents, set forth in Section 2.1, 2.2. and 2.4 above. (b) To the best of Roche's knowledge, Exhibit "1" constitutes a complete list of all granted U.S. patents (or where a corresponding U.S. patent is not granted as of the Effective Time, then a representative corresponding published U.S. or European patent application is listed) owned by Roche or its Affiliates as of the Effective Time and available for license to IGEN, which meet the criteria of Section 1.19 herein. IGEN's exclusive remedy for a breach of the foregoing representation and warranty shall be inclusion of the missing patents in Exhibit 1 as required by Section 1.19 herein. For the purposes of such list, where a U.S. patent application from which priority has been claimed has been abandoned and succeeded by one or more continuations and/or continuations-in-part, any such granted continuations and/or continuations-in-part, will be listed. Where no such U.S. Licensed Patents have been issued, the granted non-U.S. Licensed Patents or corresponding representative published application are listed. Subject to the terms, conditions and limitations of this Agreement, IGEN, its Affiliates and End-Users shall be immune from any suit for infringement of any patent rights which would constitute a failure of this representation and warranty. (c) The execution, delivery and performance of, and the consummation by Roche of the transactions contemplated by, this Agreement have been duly authorized by all necessary action, and the execution, delivery and performance of, and no further consents are needed in order to consummate the transactions contemplated hereby. A-13-21 (d) This Agreement, when executed and delivered by IGEN in accordance with the provisions hereof, shall be a legal, valid and binding obligation of Roche, enforceable against Roche in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or similar laws affecting the enforcement of creditors' rights generally and by limitations on the availability of specific performance and other equitable remedies against Roche. (e) Roche's execution of this Agreement shall not constitute a breach or default under any contract, instrument or agreement to which Roche or any of its Affiliates is a Party or by which Roche or any of its Affiliates is bound. (f) All persons who will execute this Agreement on behalf of Roche/Basle have been duly authorized to do so by all necessary action on the part of Roche/Basle, and all persons who will execute this Agreement on behalf of Roche/Germany have been duly authorized to do so by all necessary action on the part of Roche/Germany, and all persons who will execute this Agreement on behalf of Roche/USA have been duly authorized to do so by all necessary action on the part of Roche/USA. 10.3 No Other Representations or Warranties. Except as otherwise expressly set forth herein, the Parties make no other representation or warranty, express or implied, with regard to PCR or any other matter hereunder whatsoever. ARTICLE 11 DISPUTE RESOLUTION; VENUE AND CHOICE OF LAW 11.1 Good Faith Resolution. In the event that at any time during the term of this Agreement a disagreement, dispute, controversy or claim should arise out of or relating to the interpretation of this Agreement, or performance by a Party under this Agreement, or a breach of this Agreement by a Party, or any claim by a Party that any provision of this Agreement is invalid (a "Dispute" or collectively "Disputes"), one Party shall give written notice to the other Party that a dispute exists and the Parties will then attempt in good faith to resolve their differences before resorting to arbitration provided in Section 11.2. If the Parties cannot resolve the disputed matter within thirty (30) days after such notice, then either Party shall be free to submit the disputed matter to binding arbitration in accordance with Section 11.2 hereof. For purposes of this Article 11, the terms "Party" and "Parties" shall include each of the signatories to this Agreement and/or any one or more of their respective Affiliates, whether the reference is to a Party as a claimant or a Party against which a claim is made. 11.2 Arbitration. (a) The Parties intend Section 11.2 hereof to be enforceable in accordance with the Federal Arbitration Act (9 U.S.C. Section 1, et seq.), including any amendments to that Act which are subsequently adopted, notwithstanding any other choice of law provision set forth in this Agreement. In the event that either Party refuses to submit to arbitration as required herein, the other Party may request a United States District Court to compel arbitration in accordance with the Federal Arbitration Act. (b) Any dispute or other matter in question between Roche and IGEN arising out of or relating to the formation, interpretation, performance, or breach of this Agreement, whether such dispute or matter arises before or after termination of this Agreement, shall be resolved solely by arbitration if the Parties are unable to resolve the dispute through negotiation pursuant to Section 11.1 hereof. Arbitration shall be initiated by the delivery of a written notice of demand for arbitration by one Party to the other. The date on which the other Party receives such written notice shall be hereinafter referred to as the "Arbitration Notice Date." (c) Each Party shall appoint an individual as arbitrator and the two so appointed shall then appoint a third arbitrator. If either Party refuses or neglects to appoint an arbitrator within thirty (30) A-13-22 days after the Arbitration Notice Date, then the arbitration shall be conducted by a single arbitrator appointed by the American Arbitration Association. If two arbitrators are appointed but do not agree on the third arbitrator within sixty (60) days after the Arbitration Notice Date, each of the arbitrators shall nominate within sixty-seven (67) days after the Arbitration Notice Date three individuals. Each arbitrator shall then within seventy-two (72) days after the Arbitration Notice Date decline two of the nominations presented by the other arbitrator. The third arbitrator shall then be chosen from the remaining two nominations by drawing lots. Notwithstanding anything contained herein to the contrary, if the third arbitrator is not chosen with seventy-two (72) days after the Arbitration Notice Date, then the American Arbitration Association shall appoint the third arbitrator within seventy-seven (77) days after the Arbitration Notice Date. The arbitrators shall not be or have been affiliated with, or have any personal, financial or business relationship with, either of the Parties or any Affiliate of either Party; the arbitrators shall not have a personal or financial interest in the result of the arbitration. (d) The arbitration hearings shall be held in Borough of Manhattan, State of New York or such other place as may be mutually agreed by the Parties, shall be conducted in the English language and shall be conducted as confidential proceedings (except to the extent necessary to enforce the award resulting therefrom). Unless the Parties agree otherwise, the arbitrators shall commence the arbitration hearing within thirty (30) days after the selection of the third arbitrator. The arbitrators shall issue orders to protect the confidentiality of proprietary information, trade secrets and other sensitive information disclosed. Pending the arbitration hearing, at the request of a Party, the arbitrators may issue temporary injunctive or other equitable relief to address any violation or threatened violation of this Agreement. All awards shall be made based on a majority vote of the arbitrators, shall be in writing, shall not be considered confidential information of either Party, shall be issued within sixty (60) days after hearings before the arbitrators are completed, and shall state the reasoning on which the award rests unless the Parties agree otherwise. In addition to any relief at law which may be available to an aggrieved Party for such breach, such Party shall be entitled to injunctive and other equitable relief as the arbitration panel may grant. The arbitrators shall deliver a copy of the award to each Party personally or by registered mail. Any party may request within ten (10) days after receiving the decision that, for good cause, the arbitrators reconsider and modify such decision. The arbitrators shall have thirty (30) days after such request to modify their decision, if they consider it appropriate. Thereafter, the decision of the arbitrators shall be final, binding and nonappealable, except to the extent appeals are permitted by the Federal Arbitration Act, with respect to all persons, including (without limitation) persons who have failed or refused to participate in the arbitration process. Judgment upon the award rendered may be entered in any court having jurisdiction thereof. (e) Each Party shall bear its own costs in connection with any such arbitration including, without limitation, (i) all legal, accounting, and any other professional fees and expenses, (ii) the fees and expenses of its own arbitrator, and (iii) all other costs and expenses each Party incurs to prepare for such arbitration. Other than set forth above, each side shall pay, (iv) one-half of the fee and expenses of the third arbitrator, and (v) one-half of the other expenses that the Parties jointly incur directly related to the arbitration proceeding. (f) Except as provided above, arbitration shall be based upon the Commercial Arbitration Rules of the American Arbitration Association. Discovery shall be limited at the discretion of the arbitrators, so that the timing and extent of such discovery shall not interfere with the normal business operations of the Parties. The arbitrators may proceed to an award notwithstanding the failure of either Party to participate in the proceedings. (g) In the event of subsequent actions or proceedings to confirm the award or to enforce the judgment entered thereon or any other rights flowing therefrom, the prevailing Party shall be entitled to recover its reasonable attorney's fees incurred in such actions or proceedings. A-13-23 (h) The fact that the dispute resolution procedures specified in this Article 11 shall have been or may be invoked shall not excuse any Party from performing its obligations under this Agreement, and during the pendency of any such procedure the Parties shall continue to perform their respective obligations in good faith. 11.3 Limited Recourse to Courts. This Article 11 shall be the exclusive dispute resolution procedure for Disputes under this Agreement and no Party shall bring Disputes before any court, except as appeals to arbitration awards are permitted by Section 11.2. Except as permitted by Section 11.2, the Parties hereby waive any right to appeal an arbitration award to any court. The provisions of Section 11.2 may be enforced, and judgment on the award (including without limitation equitable remedies) granted in any arbitration hereunder may be entered, in any court of competent jurisdiction. The Parties hereby submit to the non-exclusive in personam jurisdiction of the federal courts in New York for such purposes. THE PARTIES HEREBY WAIVE ANY AND ALL RIGHTS TO TRIAL BY JURY FOR MATTERS RELATED TO DISPUTES SUBMITTED TO ANY COURT. 11.4 Governing Law. This Agreement is made in accordance with and shall be governed and construed under the laws of the State of New York, U.S.A., without regard to its conflicts of laws rules.

The Party subject to such Action (the "Controlling Party") shall have the exclusive right and obligation to defend and control the defense of any such Action using counsel of its own choice; provided that the Controlling Party shall not enter into any settlement of such Action without the written consent of the other Party, which consent may be withheld in the unfettered discretion of the other Party if such settlement admits the invalidity or unenforceability of any patent rights of the other Party, and otherwise may not be unreasonably withheld. The Controlling Party agrees to keep the other Party reasonably informed of all material developments in connection with any Action. 6.2 IGEN shall assume full responsibility for its and its Affiliates' performance, use and sale of the Licensed Services and Licensed Animal Services and shall defend, indemnify and hold RMS (and its Affiliates, sublicensees and licensors and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of the heirs, executors, successors and assigns of the foregoing) harmless from and against all claims, damages, losses, costs and expenses (including reasonable attorneys' fees) for death, personal injury, illness, property damage or any other injury or damage, including any damages or expenses arising in connection with state or federal regulatory action (collectively "Damages"), resulting from or arising out of liability in any way relating to the performance, use and sale by IGEN or its Affiliates, including its officers, directors, agents and employees, of the Licensed Services and Licensed Animal Services. 6.3 Waiver of Claims. IGEN shall not assert, and IGEN shall ensure that its Affiliates do not assert, any claims against ROCHE for any matter for which IGEN has provided indemnity to ROCHE under Sections 6.2 and 6.4 hereof. IGEN shall indemnify, hold harmless and defend ROCHE against any such claims. 6.4 Breach by Affiliate. Failure of an Affiliate to adopt and satisfy a condition stated in this Agreement applicable to IGEN or an Affiliate shall be considered a breach of this Agreement by IGEN. IGEN and such Affiliate shall be jointly and severally responsible for and indemnify ROCHE and its Affiliates (and their respective officers, directors, shareholders, representatives, employees, consultants and agents and each of the heirs, executors, successors and assigns of the foregoing) against any loss, cost, damage or liability (including reasonable attorneys' fees) arising from the breach by such Affiliate of this Agreement. A-14-12 ARTICLE 7 PATENT ENFORCEMENT 7.1 Continuing Royalty Payment Obligations. IGEN's obligation to pay royalties on the Net Service Revenue of Licensed Services or Licensed Animal Services performed by IGEN and its Affiliates shall remain in effect to the extent provided for in this Agreement notwithstanding any alleged infringement by any Third Party of any of the Licensed Patents. 7.2 No IGEN Right to Enforce the Licensed Patents. It is expressly understood that nothing contained herein shall in any way grant or be construed to grant to IGEN the right to enforce the Licensed Patents. Roche shall have the sole right to bring legal action to enforce the Licensed Patents against any alleged Infringement by any Third Party. ARTICLE 8 TERM AND TERMINATION 8.1 Term. The term of this Agreement shall commence as of the Effective Time and shall continue in full force and effect, unless terminated sooner in accordance with Section 8.2 below, until the expiration date of the last to expire of the Valid Claims of the Licensed Patents. 8.2 Termination. This Agreement, and the licenses granted to IGEN and its Affiliates herein, are perpetual and irrevocable, except to the extent termination is permitted in this Section 8.2: (a) IGEN may terminate this Agreement with respect to all or any one or more of the Licensed Patents for any reason by written notice to Roche at any time during the term of this Agreement. (b) [Reserved for future use]. (c) In the event that IGEN does not make any royalty payments which are due and payable, Roche may deliver written notice thereof to IGEN. If IGEN, within sixty (60) days after delivery of such notice to IGEN (the "Notice Period"), makes such payment to Roche, then Roche shall not have the right to terminate this Agreement for such non-payment. If, at the expiration of the Notice Period, IGEN has neither paid such royalty payment to Roche nor disputed the payment obligation in a written notice to Roche, then Roche may, upon written notice to IGEN following the Notice Period, terminate this Agreement. If, during the Notice Period, IGEN provides written notice to Roche that IGEN disputes such payment obligation, then the Parties shall arbitrate such dispute in accordance with Section 11.2. If the arbitration award requires IGEN to pay all or any portion of such royalty payments to Roche (the "Arbitrated Amount"), then IGEN shall pay such Arbitrated Amount to Roche within thirty (30) days after final resolution of the dispute or, if IGEN fails to do so, Roche may, upon written notice to IGEN following such 30-day period, terminate this Agreement. If the arbitration award does not require IGEN to pay any portion of such royalty payments to Roche, then Roche shall not have the right to terminate this Agreement with respect to such claimed non- payment. (d) Bankruptcy. IGEN shall retain the rights granted to it as a licensee under Section 365(n) of the United States Bankruptcy Code in case of the bankruptcy, insolvency or winding-up of ROCHE. (e) Expiration or termination of this Agreement shall not affect the ability of any Party to seek resolution of any matter arising prior to such expiration or termination pursuant to Article 11 herein. (f) The Parties agree that the provisions of this Section 8.2 shall not be considered when making the determination pursuant to Section 4.11(a), nor amended in the event of exercise of Section 4.11(b). A-14-13 (g) In the event of the termination of any license, in whole or in part, under this Agreement, the performance by IGEN and its Affiliates of services covered by such license shall cease immediately to the extent that such performance no longer is licensed as a result of such termination. 8.3 Survival of Certain Rights Upon Expiration or Termination. All rights granted to and obligations undertaken by the Parties hereunder shall terminate immediately upon the expiration of the term of this Agreement (as set forth in Section 8.1 above) or the termination of this Agreement (pursuant to Section 8.2 above) except for: (a) The obligations of IGEN to pay any and all royalties or other consideration accrued hereunder prior to such expiration or termination; (b) The right of Roche to have audited by an independent certified public accounting firm the books and records of IGEN and IGEN's Affiliates as provided in Section 4.8 above; (c) The indemnification provisions of Section 6.2 above; (d) The procedures set forth in Article 11 herein in respect of any matter arising prior to such expiration or termination; and (e) Any and all confidentiality obligations provided for in this Agreement; and (f) Sections 4.9, 8.2(e), 8.2(g), 8.3, 10, 12.1, 12.3, 12.5, 12.8, 12.9, 12.10, 12.14, 12.15, 12.17, 12.18 and 12.20. ARTICLE 9 ADDITIONAL COVENANTS AND AGREEMENTS 9.1 IGEN shall not, and shall cause each of its Affiliates not to, enter into a joint venture or other arrangement with any Third Party that would result in the conveyance to such Third Party of benefits substantially equivalent to those that would be received from a sublicense under the Licensed Patents licensed under this Agreement. 9.2 IGEN shall not, and shall cause each of its Affiliates not to, arrange the performance of Licensed Services or Licensed Animal Services (or utilize the definitions relating thereto) to reduce in bad faith the Net Service Revenues for which royalties are payable by IGEN hereunder. ARTICLE 10 REPRESENTATIONS AND WARRANTIES 10.1 Representations and Warranties of IGEN. IGEN hereby represents and warrants to Roche as follows: (a) The execution, delivery and performance of, and the consummation by IGEN of the transactions contemplated by, this Agreement have been duly authorized by all necessary action on the part of IGEN and no further consents by IGEN are needed in order to consummate the transactions contemplated hereby. (b) This Agreement, when executed and delivered by Roche/Basle, Roche/Germany and Roche/USA in accordance with the provisions hereof, shall be a legal, valid and binding obligation of IGEN, enforceable against IGEN in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or similar laws affecting the enforcement of creditors' rights generally and by limitations on the availability of specific performance and other equitable remedies against IGEN. A-14-14 (c) IGEN's execution of this Agreement shall not constitute a breach or default under any contract, instrument or agreement to which IGEN or any of its Affiliates is a Party or by which IGEN or any of its Affiliates is bound. (d) All persons who will execute this Agreement on behalf of IGEN have been duly authorized to do so by all necessary action on the part of IGEN. 10.2 Representations and Warranties of Roche. Roche hereby represents and warrants to IGEN as follows: (a) Roche/Basle has the full power and right to grant to IGEN and IGEN's Affiliates the license outside of the United States under the Licensed Patents, and Roche/USA has the full power and right to grant to IGEN and IGEN's Affiliates the license in the United States under the Licensed Patents, set forth in Section 2.1. (b) To the best of Roche's knowledge, Exhibit "1" constitutes a complete list of all granted U.S. patents (or where a corresponding U.S. patent is not granted as of the Effective Time, then a representative corresponding published U.S. or European patent application is listed) owned by Roche or its Affiliates as of the Effective Time and available for license to IGEN, which meet the criteria of Section 1.19 herein. IGEN's exclusive remedy for a breach of the foregoing representation and warranty shall be inclusion of the missing patents in Exhibit 1 as required by Section 1.19 herein. For the purposes of such list, where a U.S. patent application from which priority has been claimed has been abandoned and succeeded by one or more continuations and/or continuations-in-part, any such granted continuations and/or continuations-in-part, will be listed. Where no such U.S. Licensed Patents have been issued, the granted non-U.S. Licensed Patents or corresponding representative published application are listed. Subject to the terms, conditions and limitations of this Agreement, IGEN, its Affiliates and customers shall be immune from any suit for infringement of any patent rights which would constitute a failure of this representation and warranty. (c) The execution, delivery and performance of, and the consummation by Roche of the transactions contemplated by, this Agreement have been duly authorized by all necessary action, and the execution, delivery and performance of, and no further consents are needed in order to consummate the transactions contemplated hereby. (d) This Agreement, when executed and delivered by IGEN in accordance with the provisions hereof, shall be a legal, valid and binding obligation of Roche, enforceable against Roche in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or similar laws affecting the enforcement of creditors' rights generally and by limitations on the availability of specific performance and other equitable remedies against Roche. (e) Roche's execution of this Agreement shall not constitute a breach or default under any contract, instrument or agreement to which Roche or any of its Affiliates is a Party or by which Roche or any of its Affiliates is bound. (f) All persons who will execute this Agreement on behalf of Roche/Basle have been duly authorized to do so by all necessary action on the part of Roche/Basle, and all persons who will execute this Agreement on behalf of Roche/Germany have been duly authorized to do so by all necessary action on the part of Roche/Germany, and all persons who will execute this Agreement on behalf of Roche/USA have been duly authorized to do so by all necessary action on the part of Roche/USA. 10.3 No Other Representations or Warranties. Except as otherwise expressly set forth herein, the Parties make no other representation or warranty, express or implied, with regard to PCR or any other matter hereunder whatsoever. A-14-15 ARTICLE 11 DISPUTE RESOLUTION; VENUE AND CHOICE OF LAW 11.1 Good Faith Resolution. In the event that at any time during the term of this Agreement a disagreement, dispute, controversy or claim should arise out of or relating to the interpretation of this Agreement, or performance by a Party under this Agreement, or a breach of this Agreement by a Party, or any claim by a Party that any provision of this Agreement is invalid (a "Dispute" or collectively "Disputes"), one Party shall give written notice to the other Party that a dispute exists and the Parties will then attempt in good faith to resolve their differences before resorting to arbitration provided in Section 11.2. If the Parties cannot resolve the disputed matter within thirty (30) days after such notice, then either Party shall be free to submit the disputed matter to binding arbitration in accordance with Section 11.2 hereof. For purposes of this Article 11, the terms "Party" and "Parties" shall include each of the signatories to this Agreement and/or any one or more of their respective Affiliates, whether the reference is to a Party as a claimant or a Party against which a claim is made. 11.2 Arbitration. (a) The Parties intend Section 11.2 hereof to be enforceable in accordance with the Federal Arbitration Act (9 U.S.C. Section 1, et seq.), including any amendments to that Act which are subsequently adopted, notwithstanding any other choice of law provision set forth in this Agreement. In the event that either Party refuses to submit to arbitration as required herein, the other Party may request a United States District Court to compel arbitration in accordance with the Federal Arbitration Act. (b) Any dispute or other matter in question between Roche and IGEN arising out of or relating to the formation, interpretation, performance, or breach of this Agreement, whether such dispute or matter arises before or after termination of this Agreement, shall be resolved solely by arbitration if the Parties are unable to resolve the dispute through negotiation pursuant to Section 11.1 hereof. Arbitration shall be initiated by the delivery of a written notice of demand for arbitration by one Party to the other. The date on which the other Party receives such written notice shall be hereinafter referred to as the "Arbitration Notice Date." (c) Each Party shall appoint an individual as arbitrator and the two so appointed shall then appoint a third arbitrator. If either Party refuses or neglects to appoint an arbitrator within thirty (30) days after the Arbitration Notice Date, then the arbitration shall be conducted by a single arbitrator appointed by the American Arbitration Association. If two arbitrators are appointed but do not agree on the third arbitrator within sixty (60) days after the Arbitration Notice Date, each of the arbitrators shall nominate within sixty-seven (67) days after the Arbitration Notice Date three individuals. Each arbitrator shall then within seventy-two (72) days after the Arbitration Notice Date decline two of the nominations presented by the other arbitrator. The third arbitrator shall then be chosen from the remaining two nominations by drawing lots. Notwithstanding anything contained herein to the contrary, if the third arbitrator is not chosen with seventy-two (72) days after the Arbitration Notice Date, then the American Arbitration Association shall appoint the third arbitrator within seventy-seven (77) days after the Arbitration Notice Date. The arbitrators shall not be or have been affiliated with, or have any personal, financial or business relationship with, either of the Parties or any Affiliate of either Party; the arbitrators shall not have a personal or financial interest in the result of the arbitration. (d) The arbitration hearings shall be held in Borough of Manhattan, State of New York or such other place as may be mutually agreed by the Parties, shall be conducted in the English language and shall be conducted as confidential proceedings (except to the extent necessary to enforce the award resulting therefrom). Unless the Parties agree otherwise, the arbitrators shall commence the arbitration hearing within thirty (30) days after the selection of the third arbitrator. The arbitrators shall issue orders to protect the confidentiality of proprietary information, trade secrets and other sensitive information disclosed. Pending the arbitration hearing, at the request of a Party, the A-14-16 arbitrators may issue temporary injunctive or other equitable relief to address any violation or threatened violation of this Agreement. All awards shall be made based on a majority vote of the arbitrators, shall be in writing, shall not be considered confidential information of either Party, shall be issued within sixty (60) days after hearings before the arbitrators are completed, and shall state the reasoning on which the award rests unless the Parties agree otherwise. In addition to any relief at law which may be available to an aggrieved Party for such breach, such Party shall be entitled to injunctive and other equitable relief as the arbitration panel may grant. The arbitrators shall deliver a copy of the award to each Party personally or by registered mail. Any party may request within ten (10) days after receiving the decision that, for good cause, the arbitrators reconsider and modify such decision. The arbitrators shall have thirty (30) days after such request to modify their decision, if they consider it appropriate. Thereafter, the decision of the arbitrators shall be final, binding and nonappealable, except to the extent appeals are permitted by the Federal Arbitration Act, with respect to all persons, including (without limitation) persons who have failed or refused to participate in the arbitration process. Judgment upon the award rendered may be entered in any court having jurisdiction thereof. (e) Each Party shall bear its own costs in connection with any such arbitration including, without limitation, (i) all legal, accounting, and any other professional fees and expenses, (ii) the fees and expenses of its own arbitrator, and (iii) all other costs and expenses each Party incurs to prepare for such arbitration. Other than set forth above, each side shall pay, (iv) one-half of the fee and expenses of the third arbitrator, and (v) one-half of the other expenses that the Parties jointly incur directly related to the arbitration proceeding. (f) Except as provided above, arbitration shall be based upon the Commercial Arbitration Rules of the American Arbitration Association. Discovery shall be limited at the discretion of the arbitrators, so that the timing and extent of such discovery shall not interfere with the normal business operations of the Parties. The arbitrators may proceed to an award notwithstanding the failure of either Party to participate in the proceedings. (g) In the event of subsequent actions or proceedings to confirm the award or to enforce the judgment entered thereon or any other rights flowing therefrom, the prevailing Party shall be entitled to recover its reasonable attorney's fees incurred in such actions or proceedings. (h) The fact that the dispute resolution procedures specified in this Article 11 shall have been or may be invoked shall not excuse any Party from performing its obligations under this Agreement, and during the pendency of any such procedure the Parties shall continue to perform their respective obligations in good faith. 11.3 Limited Recourse to Courts. This Article 11 shall be the exclusive dispute resolution procedure for Disputes under this Agreement and no Party shall bring Disputes before any court, except as appeals to arbitration awards are permitted by Section 11.2. Except as permitted by Section 11.2, the Parties hereby waive any right to appeal an arbitration award to any court. The provisions of Section 11.2 may be enforced, and judgment on the award (including without limitation equitable remedies) granted in any arbitration hereunder may be entered, in any court of competent jurisdiction. The Parties hereby submit to the non-exclusive in personam jurisdiction of the federal courts in New York for such purposes. THE PARTIES HEREBY WAIVE ANY AND ALL RIGHTS TO TRIAL BY JURY FOR MATTERS RELATED TO DISPUTES SUBMITTED TO ANY COURT. 11.4 Governing Law. This Agreement is made in accordance with and shall be governed and construed under the laws of the State of New York, U.S.A., without regard to its conflicts of laws rules.

THE LIMITATION OF DAMAGES IN CLAUSE (B) ABOVE SHALL NOT APPLY TO DAMAGES PAID TO UNRELATED THIRD PARTIES (WHETHER PURSUANT TO JUDGMENT OR SETTLEMENT) FOR WHICH A PARTY HAS AN OBLIGATION TO INDEMNIFY THE OTHER PARTY HEREUNDER. 12.2 [Reserved for future use]. 12.3 Additional Documents.

ROCHE and IGEN agree for themselves and their Affiliates, and on behalf of their respective officers, employees and agents, that until the later of (i) 10 years from the Effective Time hereof or (ii) 5 years after the expiration date of this Agreement, each will treat as confidential, using the same degree of care as it uses for its own confidential and proprietary information, but in no event less than reasonable care, and shall not disclose to any Third Party, and shall not use for its own benefit or the benefit of any Third Party (except as permitted hereunder, including disclosures to IGEN Affiliates and permitted subcontractors to the extent necessary to have the services licensed hereunder performed and subject to confidentiality obligations at least as restrictive as those contained herein) the confidential information furnished to it by the other Party unless the furnishing party ("Discloser") A-14-18 otherwise agrees in writing or unless such information clearly and convincingly falls within the following exceptions: (a) Such confidential information was known to the receiving party ("Recipient") prior to the time of disclosure by the Discloser or was in the public domain at the time of disclosure by Discloser as can be documented by written records; or (b) Such confidential information is or becomes publicly known after disclosure by Discloser through no fault or omission attributable to Recipient; or (c) Such confidential information is given to Recipient from sources independent of Discloser who have the right to disclose it; or (d) Such confidential information is independently developed by employees of Recipient that did not have access to it as can be documented by written records; or (e) Recipient is required to disclose such confidential information to a court of law or to appropriate governmental agencies to enable Recipient to carry out the evaluation of a Product or to secure a governmental approval, or as otherwise required by law; provided, however, that (1) Recipient gives the Discloser prompt written notice of such required disclosure and reasonably assists the Discloser in its efforts to prevent or limit such disclosure; and (2) any confidential information disclosed pursuant to this Section 12.5(e) shall otherwise remain confidential information for the purposes of this Agreement.

Access to such confidential information must be restricted to the Recipient's, its Affiliate's or subcontractor's, employees or agents with a need to have access. The Recipient acknowledges that by virtue of this Agreement it acquires only such rights as set forth under the terms and conditions of this Agreement and only so long as it is in effect and does not acquire any rights of ownership or title in the Discloser's confidential information. In addition, each of the Parties agrees to execute appropriate confidentiality agreements with Third Party collaborators of such Party prior to disclosing the other Party's confidential information to such Third Party collaborator. Upon expiration of this Agreement, each Party, its Affiliates or subcontractors and their employees and agents shall immediately discontinue use of the other's confidential information, except as otherwise permitted under the provisions hereof. The Parties agree that this Section 12.5 sets out in its entirety the Parties' confidentiality obligations with respect to the subject matter of this Agreement. Neither Party nor any of its Affiliates shall make any public announcement of or otherwise disclose to any Third Party this Agreement or any of its terms without the prior written consent of the other Party. 12.6 License Registration. IGEN shall pay all costs and legal fees connected with registration of this Agreement in those countries where it (or its Affiliates and/or agents) performs Licensed Services and Licensed Animal Services, where required, and shall otherwise ensure that the laws of all the countries where performance of its Licensed Services and Licensed Animal Services occurs are fully satisfied. None of such amounts shall be deductible against amounts payable to ROCHE hereunder. ROCHE shall provide reasonable assistance to IGEN in effecting such registrations if IGEN reimburses any out-of-pocket expenses incurred in providing such assistance. 12.7 Reservation of Rights. ROCHE reserves the right to use for any purpose (commercial or noncommercial), anywhere in the world, and the right to allow other persons to use for any purpose, anywhere in the world, any Licensed Patents licensed hereunder, without ROCHE or such other persons being obligated to pay IGEN any royalties or other compensation. 12.8 Waiver. No delay or omission on the part of either Party to this Agreement in requiring performance by the other Party or in exercising any right hereunder shall operate as a waiver of any provision hereof or of any right or rights hereunder; and the waiver, omission or delay in requiring performance or exercising any right hereunder on any one occasion shall not be construed as a bar to or waiver of such performance or right, or of any right or remedy under this Agreement, on any future A-14-19 occasion. Any agreement on the part of either Party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such Party. 12.9 Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their permitted successors and assigns; provided, however, that: (a) neither Party shall assign any of its rights and obligations hereunder except as consented to by the other Party, which consent shall not be unreasonably withheld, and (b) such consent shall not be required with respect to an assignment of (i) any or all of its rights and obligations hereunder to an Affiliate of such assigning party; or (ii) all (but not less than all) of its rights and obligations hereunder to an acquirer of all or substantially all of the assets or business of the assigning party related to such party's use of the Licensed Patents, whether as incident to a merger, consolidation, reorganization, acquisition or otherwise.

DREISMANN ---------------------------------- Name: Heiner Dreismann Title: President, Roche Molecular Systems A-14-24 ANNEX 15 LEHMAN BROTHERS July 24, 2003 Board of Directors IGEN International, Inc. 16020 Industrial Drive Gaithersburg, MD 20877 Members of the Board: We understand that IGEN International, Inc. (the "Company") intends to enter into an agreement and plan of merger (the "Agreement") with Roche Holding Ltd ("Roche"), its subsidiary, 66 Acquisition Corporation II, and NewCo (as defined below), pursuant to which (1) Roche will purchase 100% of the outstanding common stock of the Company for $47.25 per share, and (2) a subsidiary ("NewCo") of the Company containing certain assets and liabilities of the Company will simultaneously be spun-off to IGEN stockholders in a taxable transaction ("the Proposed Transaction"). The terms and conditions of the Proposed Transaction are set forth in more detail in the Agreement. We have been requested by the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the Company's stockholders of the consideration to be received by such stockholders in the Proposed Transaction. In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and the specific terms of the Proposed Transaction; (2) publicly available information concerning the Company and Roche that we believe to be relevant to our analysis; (3) financial and operating information with respect to the business, operations and prospects of the Company and NewCo furnished to us by the Company, including, without limitation, certain projections of future financial performance of the Company and NewCo prepared by the management of the Company; (4) a trading history of the Company's common stock from its initial public offering on February 3, 1994 to the present; (5) a comparison of the historical financial results and present financial condition of the Company with those of other companies that we deemed relevant; and (6) a comparison of the financial terms of the Proposed Transaction with the financial terms of certain other transactions that we deemed relevant. In addition, we have had discussions with the management of the Company concerning its business, operations, assets, financial condition and prospects and have undertaken such other studies, analyses and investigations as we deemed appropriate. In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without assuming any responsibility for independent verification of such information and have further relied upon the assurances of management of the Company that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of the Company and NewCo, upon advice of the Company, we have assumed that such projections have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of the Company and NewCo and that the Company and NewCo will perform substantially in accordance with such projections. In addition, you have not authorized us to solicit, and we have not solicited, any indications of interest from any third party with respect to the purchase of all or a part of the Company's business. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter. A-15-1 LEHMAN BROTHERS IGEN International, Inc. July 24, 2003 Page 2 Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the consideration to be received by the stockholders of the Company in the Proposed Transaction is fair to such stockholders. We are acting as financial advisor to the Company in connection with the Proposed Transaction and will receive a fee for our services in connection therewith. In addition, the Company has agreed to indemnify us for certain liabilities that may arise out of the rendering of this opinion. We also have performed various investment banking services for the Company in the past and have received customary fees for such services. In the ordinary course of our business, we may actively trade in the debt and equity securities of the Company and Roche for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities. This opinion is for the use and benefit of the Board of Directors of the Company in connection with its consideration of the Proposed Transaction. This opinion is not intended to be, and does not constitute, a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the Proposed Transaction. Very truly yours, LEHMAN BROTHERS By: /s/ FREDERICK FRANK ------------------------------------ Vice Chairman A-15-2 ANNEX 16 BIOVERIS CORPORATION 2003 STOCK INCENTIVE PLAN 1. Purpose The purpose of this 2003 Stock Incentive Plan (the "Plan") of BioVeris Corporation, a Delaware corporation (the "Company"), is to advance the interests of the Company's stockholders by enhancing the Company's ability to attract, retain and motivate persons who make (or are expected to make) important contributions to the Company by providing such persons with equity ownership opportunities and performance-based incentives and thereby better aligning the interests of such persons with those of the Company's stockholders. Except where the context otherwise requires, the term "Company" shall include any of the Company's present or future parent or subsidiary corporations as defined in Sections 424(e) or (f) of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the "Code") and any other business venture (including, without limitation, joint venture or limited liability company) in which the Company has a controlling interest, as determined by the Board of Directors of the Company (the "Board"). 2. Eligibility All of the Company's employees, officers, directors, consultants and advisors are eligible to be granted options, restricted stock or other stock-based awards (each, an "Award") under the Plan. Each person who has been granted an Award under the Plan shall be deemed a "Participant". 3. Administration and Delegation (a) Administration by Board of Directors. The Plan will be administered by the Board. The Board shall have authority to grant Awards and to adopt, amend and repeal such administrative rules, guidelines and practices relating to the Plan as it shall deem advisable. The Board may correct any defect, supply any omission or reconcile any inconsistency in the Plan or any Award in the manner and to the extent it shall deem expedient to carry the Plan into effect and it shall be the sole and final judge of such expediency. All decisions by the Board shall be made in the Board's sole discretion and shall be final and binding on all persons having or claiming any interest in the Plan or in any Award. No director or person acting pursuant to the authority delegated by the Board shall be liable for any action or determination relating to or under the Plan made in good faith. (b) Appointment of Committees. To the extent permitted by applicable law, the Board may delegate any or all of its powers under the Plan to one or more committees or subcommittees of the Board (a "Committee"), which Committee will consist of not less than two members, each member of which shall be an "outside director" within the meaning of Section 162(m) of the Code and a "non-employee director" as defined in Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). All references in the Plan to the "Board" shall mean the Board or a Committee of the Board or the executive officers referred to in Section 3(c) to the extent that the Board's powers or authority under the Plan have been delegated to such Committee or executive officers. (c) Delegation to Executive Officers. To the extent permitted by applicable law, the Board may delegate to one or more executive officers of the Company the power to grant Awards to employees or officers of the Company or any of its present or future subsidiary corporations and to exercise such other powers under the Plan as the Board may determine, provided that the Board shall fix the terms of the Awards to be granted by such executive officers (including the exercise price of such Awards, which may include a formula by which the exercise price will be determined) and the maximum number of shares subject to Awards that the executive officers may grant; provided further, however, that no executive officer shall be authorized to grant Awards to any "executive officer" of the Company (as defined by Rule 3b-7 under the Exchange Act) or to any "officer" of the Company (as defined by Rule 16a-1 under the Exchange Act). A-16-1 4. Stock Available for Awards (a) Number of Shares. Subject to adjustment under Section 8, Awards may be made under the Plan for up to 5,300,000 shares of common stock, $0.001 par value per share, of the Company (the "Common Stock"). If any Award expires or is terminated, surrendered or canceled without having been fully exercised or is forfeited in whole or in part (including as the result of shares of Common Stock subject to such Award being repurchased by the Company at the original issuance price pursuant to a contractual repurchase right) or results in any Common Stock not being issued, the unused Common Stock covered by such Award shall again be available for the grant of Awards under the Plan, subject, however, in the case of Incentive Stock Options (as hereinafter defined), to any limitations under the Code. Shares issued under the Plan may consist in whole or in part of authorized but unissued shares or treasury shares. (b) Per-Participant Limit. Subject to adjustment under Section 8, the maximum number of shares of Common Stock with respect to which Awards may be granted to any Participant under the Plan shall be 500,000 per calendar year. The per-Participant limit described in this Section 4(b) shall be construed and applied consistently with Section 162(m) of the Code ("Section 162(m)"). 5. Stock Options (a) General. The Board may grant options to purchase Common Stock (each, an "Option") and determine the number of shares of Common Stock to be covered by each Option, the exercise price of each Option and the conditions and limitations applicable to the exercise of each Option, including conditions relating to applicable federal or state securities laws, as it considers necessary or advisable. An Option which is not intended to be an Incentive Stock Option (as hereinafter defined) shall be designated a "Nonstatutory Stock Option". (b) Incentive Stock Options. An Option that the Board intends to be an "incentive stock option" as defined in Section 422 of the Code (an "Incentive Stock Option") shall only be granted to employees of BioVeris Corporation, any of BioVeris Corporation's present or future parent or subsidiary corporations as defined in Sections 424(e) or (f) of the Code, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code, and shall be subject to and shall be construed consistently with the requirements of Section 422 of the Code. The Company shall have no liability to a Participant, or any other party, if an Option (or any part thereof) that is intended to be an Incentive Stock Option is not an Incentive Stock Option. (c) Exercise Price. The Board shall establish the exercise price at the time each Option is granted and specify it in the applicable option agreement provided, however, that the exercise price shall not be less than 100% of the fair market value of the Common Stock, as determined by the Board, at the time the Option is granted. (d) Duration of Options. Each Option shall be exercisable at such times and subject to such terms and conditions as the Board may specify in the applicable option agreement, provided, however, that no Option will be granted for a term in excess of 10 years. (e) Exercise of Option. Options may be exercised by delivery to the Company of a written notice of exercise signed by the proper person or by any other form of notice (including electronic notice) approved by the Board together with payment in full as specified in Section 5(f) for the number of shares for which the Option is exercised. (f) Payment Upon Exercise. Common Stock purchased upon the exercise of an Option granted under the Plan shall be paid for as follows: (1) in cash or by check, payable to the order of the Company; (2) except as the Board may, in its sole discretion, otherwise provide in an option agreement, by (i) delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to the Company sufficient funds to pay the exercise price and any required tax withholding A-16-2 or (ii) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the Company cash or a check sufficient to pay the exercise price and any required tax withholding; (3) when the Common Stock is registered under the Exchange Act, by delivery of shares of Common Stock owned by the Participant valued at their fair market value as determined by (or in a manner approved by) the Board in good faith ("Fair Market Value"), provided (i) such method of payment is then permitted under applicable law and (ii) such Common Stock, if acquired directly from the Company, was owned by the Participant at least six months prior to such delivery; (4) to the extent permitted by applicable law and the Board, in its sole discretion by (i) delivery of a promissory note of the Participant to the Company on terms determined by the Board, or (ii) payment of such other lawful consideration as the Board may determine; or (5) by any combination of the above permitted forms of payment. (g) Substitute Options. In connection with a merger or consolidation of an entity with the Company or the acquisition by the Company of property or stock of an entity, the Board may grant Options in substitution for any options or other stock or stock-based awards granted by such entity or an affiliate thereof. Substitute Options may be granted on such terms as the Board deems appropriate in the circumstances, notwithstanding any limitations on Options contained in the other sections of this Section 5 or in Section 2. (h) Repricing. In no event shall any Option be repriced at any time during the term of such Option (other than adjustments for stock splits, stock dividends, recapitalizations and similar events as provided herein and in the documents governing such Option), without the prior affirmative vote of a majority of outstanding shares of voting stock of the Company present at a stockholders' meeting in person or by proxy and entitled to vote thereon. "Repriced" means any of the following or any other action that has the same effect: (1) lowering the strike price of an option after it is granted, (2) any other action that is treated as a repricing under generally accepted accounting principles, or (3) canceling an option at a time when its strike price exceeds the fair market value of the underlying stock, in exchange for another option, share of restricted stock, or other equity, unless the cancellation and exchange occurs in connection with a merger, acquisition, spin-off or other similar corporate transaction. Any amendment or repeal of this provision shall require the affirmative vote of a majority of outstanding shares of voting stock of the Company present at a stockholders' meeting in person or by proxy and entitled to vote thereon. (i) Director Grants. On the day following each Annual Stockholders Meeting, each non-employee director shall automatically be granted an option to purchase 4,000 shares of Common Stock. Any person who is appointed or elected as a non-employee director at any other time shall automatically be granted an option to purchase 4,000 shares of Common Stock on the date of such appointment or election. Notwithstanding anything herein to the contrary, each non-employee director of the Company who is serving at the closing of transactions contemplated by the Agreement and Plan of Merger entered into among Roche Holding Ltd, 66 Acquisition Corporation II, IGEN International, Inc. and the Company, shall receive an option to purchase 4,000 shares of Common Stock as of such closing date. 6. Restricted Stock (a) Grants. The Board may grant Awards entitling recipients to acquire shares of Common Stock, subject to the right of the Company to repurchase all or part of such shares at their issue price or other stated or formula price (or to require forfeiture of such shares if issued at no cost) from the recipient in the event that conditions specified by the Board in the applicable Award are not satisfied prior to the end of the applicable restriction period or periods established by the Board for such Award (each, a "Restricted Stock Award"). (b) Terms and Conditions. The Board shall determine the terms and conditions of any such Restricted Stock Award, including the conditions for repurchase (or forfeiture) and the issue price, if any. A-16-3 (c) Stock Certificates. Any stock certificates issued in respect of a Restricted Stock Award shall be registered in the name of the Participant and, unless otherwise determined by the Board, deposited by the Participant, together with a stock power endorsed in blank, with the Company (or its designee). At the expiration of the applicable restriction periods, the Company (or such designee) shall deliver the certificates no longer subject to such restrictions to the Participant or if the Participant has died, to the beneficiary designated, in a manner determined by the Board, by the Participant to receive amounts due or exercise rights of the Participant in the event of the Participant's death (the "Designated Beneficiary"). In the absence of an effective designation by a Participant, Designated Beneficiary shall mean the Participant's estate. 7. Other Stock-Based Awards The Board shall have the right to grant other Awards based upon the Common Stock having such terms and conditions as the Board may determine, including the grant of shares based upon certain conditions, the grant of securities convertible into Common Stock and the grant of stock appreciation rights. 8. Adjustments for Changes in Common Stock and Certain Other Events (a) Changes in Capitalization. In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any distribution to holders of Common Stock other than a normal cash dividend, (i) the number and class of securities available under this Plan, (ii) the per-Participant limit set forth in Section 4(b), (iii) the number and class of securities and exercise price per share subject to each outstanding Option or other stock-based award, and (iv) the repurchase price per share subject to each outstanding Restricted Stock Award shall be appropriately adjusted by the Company (or substituted Awards may be made, if applicable) to the extent the Board shall determine, in good faith, that such an adjustment (or substitution) is necessary and appropriate. If this Section 8(a) applies and Section 8(c) also applies to any event, Section 8(c) shall be applicable to such event, and this Section 8(a) shall not be applicable. (b) Liquidation or Dissolution. In the event of a proposed liquidation or dissolution of the Company, the Board shall upon written notice to the Participants provide that all then unexercised Options will (i) become exercisable in full as of a specified time at least 10 business days prior to the effective date of such liquidation or dissolution and (ii) terminate effective upon such liquidation or dissolution, except to the extent exercised before such effective date. The Board may specify the effect of a liquidation or dissolution on any Restricted Stock Award or other stock-based award granted under the Plan at the time of the grant. (c) Reorganization Events (1) Definition. A "Reorganization Event" shall mean: (a) any merger or consolidation of the Company with or into another entity as a result of which all of the Common Stock is converted into or exchanged for the right to receive cash, securities or other property or (b) any exchange of all of the Common Stock of the Company for cash, securities or other property pursuant to a share exchange transaction. (2) Consequences of a Reorganization Event on Options. Upon the occurrence of a Reorganization Event, or the execution by the Company of any agreement with respect to a Reorganization Event, the Board shall provide that all outstanding Options shall be assumed, or equivalent options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof). For purposes hereof, an Option shall be considered to be assumed if, following consummation of the Reorganization Event, the Option confers the right to purchase, for each share of Common Stock subject to the Option immediately prior to the consummation of the Reorganization Event, the consideration (whether cash, securities or other property) received as a result of the Reorganization Event by holders of Common Stock for each share of Common Stock held immediately prior to the consummation of the Reorganization Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a A-16-4 majority of the outstanding shares of Common Stock); provided, however, that if the consideration received as a result of the Reorganization Event is not solely common stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, provide for the consideration to be received upon the exercise of Options to consist solely of common stock of the acquiring or succeeding corporation (or an affiliate thereof) equivalent in fair market value to the per share consideration received by holders of outstanding shares of Common Stock as a result of the Reorganization Event. Notwithstanding the foregoing, if the acquiring or succeeding corporation (or an affiliate thereof) does not agree to assume, or substitute for, such Options, then the Board shall, upon written notice to the Participants, provide that all then unexercised Options will become exercisable in full as of a specified time prior to the Reorganization Event and will terminate immediately prior to the consummation of such Reorganization Event, except to the extent exercised by the Participants before the consummation of such Reorganization Event; provided, however, that in the event of a Reorganization Event under the terms of which holders of Common Stock will receive upon consummation thereof a cash payment for each share of Common Stock surrendered pursuant to such Reorganization Event (the "Acquisition Price"), then the Board may instead provide that all outstanding Options shall terminate upon consummation of such Reorganization Event and that each Participant shall receive, in exchange therefor, a cash payment equal to the amount (if any) by which (A) the Acquisition Price multiplied by the number of shares of Common Stock subject to such outstanding Options (whether or not then exercisable), exceeds (B) the aggregate exercise price of such Options. To the extent all or any portion of an Option becomes exercisable solely as a result of the first sentence of this paragraph, upon exercise of such Option the Participant shall receive shares subject to a right of repurchase by the Company or its successor at the Option exercise price. Such repurchase right (1) shall lapse at the same rate as the Option would have become exercisable under its terms and (2) shall not apply to any shares subject to the Option that were exercisable under its terms without regard to the first sentence of this paragraph. (3) Consequences of a Reorganization Event on Restricted Stock Awards. Upon the occurrence of a Reorganization Event, the repurchase and other rights of the Company under each outstanding Restricted Stock Award shall inure to the benefit of the Company's successor and shall apply to the cash, securities or other property which the Common Stock was converted into or exchanged for pursuant to such Reorganization Event in the same manner and to the same extent as they applied to the Common Stock subject to such Restricted Stock Award. 9. General Provisions Applicable to Awards (a) Transferability of Awards. Except as the Board may otherwise determine or provide in an Award, Awards shall not be sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the life of the Participant, shall be exercisable only by the Participant. References to a Participant, to the extent relevant in the context, shall include references to authorized transferees. (b) Documentation. Each Award shall be evidenced in such form (written, electronic or otherwise) as the Board shall determine. Each Award may contain terms and conditions in addition to those set forth in the Plan. (c) Board Discretion. Except as otherwise provided by the Plan, each Award may be made alone or in addition or in relation to any other Award. The terms of each Award need not be identical, and the Board need not treat Participants uniformly. The Board, in its sole discretion, may take such further action, in respect of the Plan or any Award, as it, in its sole discretion, determines to be fair and equitable in light of the circumstances presented (including without limitation in the context of a reorganization event or any change in control of BioVeris) as long as such action would not materially and adversely affect the Participant. (d) Termination of Status. The Board shall determine the effect on an Award of the disability, death, retirement, authorized leave of absence or other change in the employment or other status of a A-16-5 Participant and the extent to which, and the period during which, the Participant, the Participant's legal representative, conservator, guardian or Designated Beneficiary may exercise rights under the Award. (e) Withholding. Each Participant shall pay to the Company, or make provision satisfactory to the Board for payment of, any taxes required by law to be withheld in connection with Awards to such Participant no later than the date of the event creating the tax liability. Except as the Board may otherwise provide in an Award, when the Common Stock is registered under the Exchange Act, Participants may, at the Company's option, satisfy such tax obligations in whole or in part by delivery of shares of Common Stock, including shares retained from the Award creating the tax obligation, valued at their Fair Market Value; provided, however, that the total tax withholding where stock is being used to satisfy such tax obligations cannot exceed the Company's minimum statutory withholding obligations (based on minimum statutory withholding rates for federal and state tax purposes, including payroll taxes, that are applicable to such supplemental taxable income). The Company may, to the extent permitted by law, deduct any such tax obligations from any payment of any kind otherwise due to a Participant. (f) Amendment of Award. The Board may amend, modify or terminate any outstanding Award, including but not limited to, substituting therefor another Award of the same or a different type, changing the date of exercise or realization, and converting an Incentive Stock Option to a Nonstatutory Stock Option, provided that the Participant's consent to such action shall be required unless the Board determines that the action, taking into account any related action, would not materially and adversely affect the Participant. (g) Conditions on Delivery of Stock. The Company will not be obligated to deliver any shares of Common Stock pursuant to the Plan or to remove restrictions from shares previously delivered under the Plan until (i) all conditions of the Award have been met or removed to the satisfaction of the Company, (ii) in the opinion of the Company's counsel, all other legal matters in connection with the issuance and delivery of such shares have been satisfied, including any applicable securities laws and any applicable stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered to the Company such representations or agreements as the Company may consider appropriate to satisfy the requirements of any applicable laws, rules or regulations. (h) Acceleration. The Board may at any time provide that any Award shall become immediately exercisable in full or in part, free of some or all restrictions or conditions, or otherwise realizable in full or in part, as the case may be. 10. Miscellaneous (a) No Right To Employment or Other Status. No person shall have any claim or right to be granted an Award, and the grant of an Award shall not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under the Plan, except as expressly provided in the applicable Award. (b) No Rights As Stockholder. Subject to the provisions of the applicable Award, no Participant or Designated Beneficiary shall have any rights as a stockholder with respect to any shares of Common Stock to be distributed with respect to an Award until becoming the record holder of such shares. Notwithstanding the foregoing, in the event the Company effects a split of the Common Stock by means of a stock dividend and the exercise price of and the number of shares subject to such Option are adjusted as of the date of the distribution of the dividend (rather than as of the record date for such dividend), then a Participant who exercises an Option between the record date and the distribution date for such stock dividend shall be entitled to receive, on the distribution date, the stock dividend with respect to the shares of Common Stock acquired upon such Option exercise, notwithstanding the fact that such shares were not outstanding as of the close of business on the record date for such stock dividend. (c) Effective Date and Term of Plan. The Plan shall become effective on the date on which it is adopted by the Board, but no Award granted to a Participant that is intended to comply with Section 162(m) shall become exercisable, vested or realizable, as applicable to such Award, unless and A-16-6 until the Plan has been approved by the Company's stockholders to the extent stockholder approval is required by Section 162(m) in the manner required under Section 162(m) (including the vote required under Section 162(m)). No Awards shall be granted under the Plan after the completion of ten years from the earlier of (i) the date on which the Plan was adopted by the Board or (ii) the date the Plan was approved by the Company's stockholders, but Awards previously granted may extend beyond that date. (d) Amendment of Plan. The Board may amend, suspend or terminate the Plan or any portion thereof at any time, provided that to the extent required by Section 162(m), no Award granted to a Participant that is intended to comply with Section 162(m) after the date of such amendment shall become exercisable, realizable or vested, as applicable to such Award, unless and until such amendment shall have been approved by the Company's stockholders if required by Section 162(m) (including the vote required under Section 162(m)). (e) Governing Law. The provisions of the Plan and all Awards made hereunder shall be governed by and interpreted in accordance with the laws of the State of Delaware, without regard to any applicable conflicts of law. A-16-7 ANNEX 17 SECTION 262 Of The Delaware General Corporation Law sec. 262. Appraisal rights. (a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to sec. 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository. (b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to sec. 251 (other than a merger effected pursuant to sec. 251(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or sec. 264 of this title: (1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of sec. 251 of this title. (2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to sec.sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except: a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof; b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders; c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph. A-17-1 (3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under sec. 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation. (c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable. (d) Appraisal rights shall be perfected as follows: (1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or (2) If the merger or consolidation was approved pursuant to sec. 228 or sec. 253 of this title, then, either a constituent corporation before the effective date of the merger or consolidation, or the surviving or resulting corporation within ten days thereafter, shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, A-17-2 provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given. (e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later. (f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation. (g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. (h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may A-17-3 participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section. (i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state. (j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal. (k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just. (l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation. A-17-4 [BACK COVER OF PROSPECTUS] Until , 2004, all dealers that effect transactions in these securities, whether or not participating in this distribution, may be required to deliver a prospectus. IGN-SPS-03 PART II INFORMATION NOT REQUIRED IN THE PROSPECTUS ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS Section 145(a) of the General Corporation Law of the State of Delaware, or the Delaware Corporation Law, provides, in general, that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation, because the person is or was a director or officer of the corporation. Such indemnity may be against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and if, with respect to any criminal action or proceeding, the person did not have reasonable cause to believe the person's conduct was unlawful. Section 145(b) of the Delaware Corporation Law provides, in general, that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor because the person is or was a director or officer of the corporation, against any expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interest of the corporation, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to be indemnified for such expenses which the Court of Chancery or such other court shall deem proper. Article X of BioVeris's certificate of incorporation requires indemnification to the fullest extent authorized by Delaware law of any person who is or was a director or officer of BioVeris who was or is made a party or is threatened to be made a party to or is otherwise involved in any proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director or officer of the BioVeris or was serving at the request of the BioVeris as a director, officer, employee or agent of any other enterprise. The right to indemnification under Article X of BioVeris's certificate of incorporation is not exclusive of any right to indemnification that any person may otherwise have. BioVeris will enter into separate indemnification agreements with Messrs. Samuel Wohlstadter, Richard Massey, Joop Sistermans, Anthony Rees, Robert Salsmans, George Migausky, Don Elsey and Daniel J. Abdun-Nabi and Mrs. Nadine Wohlstadter, pursuant to which BioVeris has agreed to indemnify such officers and directors to the fullest extent authorized by law, and to purchase and maintain insurance on behalf of such officers and directors. Section 145(g) of the Delaware Corporation Law and Article X of BioVeris's certificate of incorporation permit BioVeris to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation against any liability asserted against the person and incurred by the person in any such capacity, or arising out of the person's status as such, whether or not the corporation would have the power to indemnify the person against such liability under the provisions of the law. As authorized by Section 145(g) of the Delaware Corporation Law and Article X of BioVeris's certificate of incorporation, and as required by BioVeris's indemnification agreements, BioVeris will have in effect directors' and officers' liability insurance policies. II-1 ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES (a) See Exhibit Index. (b) Not applicable. (c) Opinion of Lehman Brothers (included as Annex 15 to the proxy statement/prospectus which is a part of this registration statement). ITEM 22. UNDERTAKINGS (a)(1) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form. (2) The registrant undertakes that every prospectus (i) that is filed pursuant to paragraph (a)(1) immediately preceding, or (ii) that purports to meet the requirements of section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 20 or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. (c) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request. (d) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective. II-2 SIGNATURES Pursuant to the requirements of the Securities Act, the registrant has duly caused this amendment to the registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Gaithersburg, Maryland on this 30th day of December, 2003.
