To Our Stockholders:
 
Quanex Corporation has entered into an agreement with Gerdau S.A. and Gerdau Delaware, Inc. pursuant to which Gerdau Delaware, Inc. will merge with and into Quanex (we refer to this agreement, as it may be amended from time to time, as the merger agreement, and we refer to Gerdau S.A. as Gerdau and Gerdau Delaware, Inc. as Gerdau Delaware). Immediately prior to and in connection with the merger, Quanex will spin-off to its stockholders a subsidiary containing all of the assets comprising the Building Products Group of Quanex. We are sending this proxy statement to Quanex stockholders to ask for your vote in favor of the approval and adoption of the merger agreement. If Quanex stockholders approve and adopt the merger agreement and the merger is subsequently completed, Quanex stockholders will receive $39.20 and one share of Quanex Building Products Corporation common stock in connection with the spin-off for each share of Quanex common stock they hold as of the closing date. Quanex stockholder approval is not needed for, and you are not being asked for a proxy in relation to, the proposed spin-off of the Building Products Group of Quanex.
 
You are cordially invited to attend a special meeting of stockholders of Quanex to be held at   a.m., Central time, on February   , 2008, at the Company’s principal executive offices at 1900 West Loop South, 15th Floor, Houston, Texas. This document is a proxy statement for Quanex to use in soliciting proxies for its special meeting of stockholders. Attached is an important document containing answers to frequently asked questions and a summary description of the merger (beginning on page 1), followed by more detailed information about Quanex, the proposed merger and the merger agreement. We urge you to read this document carefully and in its entirety.
 
Our Board of Directors has unanimously approved the merger, the merger agreement and the other transactions contemplated by the merger agreement, and has declared the merger, the merger agreement and the other transactions contemplated by the merger agreement advisable and in the best interests of our company and its stockholders. Our Board of Directors unanimously recommends that you vote “FOR” the proposal to adopt the merger agreement.
 
The merger agreement must be adopted by the affirmative vote of a majority of the outstanding shares of our common stock entitled to vote on the matter. The proxy statement accompanying this letter provides you with more specific information concerning the special meeting, the merger agreement and the other transactions contemplated by the merger agreement. We encourage you to read carefully the accompanying proxy statement, including the annexes. You also may obtain more information about our company from us or from documents we have filed with the Securities and Exchange Commission.
 
Your vote is very important regardless of the number of shares of common stock that you own. Whether or not you plan to attend the special meeting, we urge you to vote and submit your proxy in order to ensure the presence of a quorum. If you fail to vote by proxy or in person, or fail to instruct your broker on how to vote, it will have the same effect as a vote against the proposal to adopt the merger agreement.
 
Therefore, we request that you authorize your proxy by completing, signing, dating and returning the enclosed proxy card as promptly as possible. The enclosed proxy card contains instructions regarding voting. If you hold your shares through an account with a broker, nominee, fiduciary or other custodian, please follow instructions you receive from them to vote your shares. If you attend the special meeting, you may continue to have your shares voted as instructed in the proxy, or you will have the right to withdraw your proxy at the special meeting and vote your shares in person.
 
Sincerely,

NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
To Be Held February   , 2008
 
 
NOTICE IS HEREBY GIVEN that a Special Meeting of Stockholders of Quanex Corporation, a Delaware corporation (the “Company”), will be held at the principal executive offices of the Company, 1900 West Loop South, Suite 1500, Houston, Texas, on February   , 2008, at   a.m., Central time, for the following purposes:
 
(1) To consider and vote upon a proposal to approve and adopt the Agreement and Plan of Merger dated as of November 18, 2007, by and among Quanex Corporation, Gerdau S.A. and Gerdau Delaware, Inc. As a result of the merger, the Company will become a wholly-owned subsidiary of Gerdau S.A. and each outstanding share of the Company’s common stock will be converted into the right to receive $39.20 per share in cash, without interest.
 
(2) To consider and vote upon a proposal to adjourn or postpone the special meeting, if necessary, to solicit additional proxies in favor of the approval and adoption of the merger agreement.
 
(3) To consider and transact such other business as may properly come before the meeting or any adjournment or adjournments thereof.
 
Information with respect to the above matters is set forth in the proxy statement that accompanies this Notice.
 
The Board of Directors has fixed the close of business on January   , 2008, as the record date for determining stockholders entitled to notice of and to vote at the meeting. A complete list of the stockholders entitled to vote at the meeting will be maintained at the Company’s principal executive offices, will be open to the examination of any stockholder for any purpose germane to the meeting during ordinary business hours for a period of ten days prior to the meeting, and will be made available at the time and place of the meeting during the whole time thereof.
 
Our Board of Directors unanimously recommends that you vote “FOR” the proposal to adopt the merger agreement and “FOR” the proposal to approve any adjournments of the special meeting for purpose of soliciting additional proxies.
 
The merger agreement must be adopted by the affirmative vote of a majority of the outstanding shares of our common stock that are entitled to vote on the matter. Any adjournments of the special meeting for the purpose of soliciting additional proxies must be approved by the affirmative vote of a majority of the outstanding shares of our common stock present in person or by proxy at the special meeting and entitled to vote on the matter. Your vote is very important regardless of the number of shares of common stock that you own. Whether or not you plan to attend the special meeting, we urge you to vote and submit your proxy in order to ensure the presence of a quorum. If you fail to vote by proxy or in person, or fail to instruct your broker on how to vote, it will have the same effect as a vote against the proposal to adopt the merger agreement but will have no effect on the outcome of the adjournment proposal.
 
We request that you authorize your proxy by completing and returning the enclosed proxy card as promptly as possible. The enclosed proxy card contains instructions regarding voting. If you hold your shares through an account with a broker, nominee, fiduciary or other custodian, please follow instructions you receive from them to vote your shares. Stockholders who do not vote “FOR” the proposal to adopt the merger agreement will have the right to seek appraisal of the fair value of their shares if the merger is completed, but only if they submit a written demand for appraisal to us before the vote is taken on the merger agreement and they comply with all other requirements of Delaware law, which requirements are summarized in the accompanying proxy statement.
 
Please execute your vote promptly.  Your designation of a proxy is revocable and will not affect your right to vote in person if you find it convenient to attend the meeting and wish to vote in person.
 
By order of the Board of Directors,
 
-s-Kevin P. Delaney

Table of Contents

 
Quanex Corporation is an industry-leading manufacturer of value-added, engineered materials and components serving the vehicular products and building products markets. Prior to the merger, Quanex intends to spin-off its Building Products Group as a separate company to its stockholders.
 
Gerdau and Gerdau Delaware
 
Gerdau S.A.
Av. Dos Farrapos, 1811
Porto Alegre, RS 90220-005
Brazil
 
The Gerdau Group is the largest long steel bar producer in the Americas, and the fourteenth largest steelmaker in the world. It has over 35,000 employees and operates in 13 countries: Argentina, Brazil, Canada, Chile, Colombia, the Dominican Republic, India, Mexico, Peru, Spain, the United States, Uruguay and Venezuela. It has an annual steel production capacity of 23.2 million metric tons and is one of the largest recyclers in the Americas. Gerdau Delaware is a wholly-owned subsidiary of Gerdau and was formed by Gerdau to participate in the merger.
 
The Merger (page 18)
 
General
 
On November 18, 2007, the companies agreed to the merger between Quanex and Gerdau Delaware under the terms of the merger agreement described in this proxy statement and attached hereto as Annex A. The merger agreement is the legal document that governs the merger, and we urge you to read that agreement.
 
At the effective time of the merger, Gerdau Delaware will merge with and into Quanex. Quanex will be the surviving company and will become a wholly-owned subsidiary of Gerdau. The separate corporate existence of Gerdau Delaware will cease at the effective time of the merger.
 
Merger Consideration
 
At the effective time of the merger, each outstanding share of Quanex (other than any shares owned directly or indirectly by Quanex or Gerdau and those shares held by dissenting stockholders) will be converted into the right to receive $39.20 in cash, without interest.
 
In connection with the merger, Quanex stockholders will receive, pursuant to the spin-off of Quanex’s Building Products Group, one share of Quanex Building Products common stock for each share of Quanex common stock they own on the closing date of the merger.
 
Treatment of Quanex Stock Options and Restricted Stock Units
 
At the effective time of the merger, Quanex stock options will become vested and exercisable and will be cancelled. The holder of such Quanex stock options will be entitled to receive an amount in cash equal to: (x) the total number of shares of Quanex common stock subject to the stock option times (y) the excess of (i) the sum of (A) $39.20 and (B) the closing sales price of a share of Quanex Building Products common stock on the NYSE on the distribution date for the spin-off of Quanex’s Building Products Group over (ii) the exercise price per share under the stock option, less any applicable tax withholding.
 
Each restricted stock unit that has been issued but has not vested prior to the effective time of the merger will become fully vested at the effective time of the merger and will be converted into the right to receive an amount per restricted stock unit equal to the sum of (a) $39.20 and (b) the closing sales price of a share of Quanex Building Products common stock on the NYSE on the distribution date for the spin-off of Quanex’s Building Products Group.
 
See “Interests of Certain Persons in the Merger” beginning on page 33 for a discussion of the treatment of restricted stock pursuant to the terms of the spin-off.

The Spin-Off
 
Immediately prior to and in connection with the merger, Quanex will spin-off to its stockholders the limited liability company interests of its building products subsidiary containing all of the assets and liabilities of Quanex’s Building Products Group known as Quanex Building Products LLC. The interests will be distributed to Quanex’s stockholders on the basis of one unit of Quanex Building Products LLC for each share of Quanex common stock outstanding. Immediately following the spin-off, Quanex Building Products LLC will merge with and into its wholly-owned subsidiary Quanex Building Products Corporation, with Quanex Building Products Corporation being the surviving company in the merger. Each unit of Quanex Building Products LLC will be converted immediately into one share of Quanex Building Products Corporation common stock. As a result, a Quanex stockholder will receive one share of Quanex Building Products Corporation common stock for each share of Quanex common stock held by such stockholder.
 
Quanex stockholder approval is not needed for, and you are not being asked for a proxy in relation to, the proposed spin-off of the Building Products Group of Quanex or the subsequent merger of Quanex Building Products LLC with and into Quanex Building Products Corporation. Holders of Quanex common stock on the record date of the spin-off, which will be the same date as the closing date of the merger, will receive an information statement describing their ownership of Quanex Building Products Corporation.
 
Material U.S. Federal Income Tax Consequences (page 29)
 
For U.S. federal income tax purposes, we will treat and report the spin-off and the merger as a single integrated transaction with respect to the Quanex stockholders in which the spin-off will be treated as a redemption of shares of Quanex common stock that qualifies for “exchange” treatment. Accordingly, with respect to each Quanex stockholder who is a citizen or resident of the United States and holds his shares of Quanex common stock as a capital asset (generally, assets held for investment), we expect that such a Quanex stockholder will generally recognize capital gain or loss for U.S. federal income tax purposes in an amount equal to the difference between (i) the sum of the amount of cash received in the merger and the fair market value, determined when the spin-off occurs, of the property received in the spin-off, and (ii) such Quanex stockholder’s adjusted tax basis in his shares of Quanex common stock immediately prior to the spin-off. The deduction of any recognized loss may be delayed or otherwise adversely affected by certain loss limitation rules. Any such gain or loss will generally be long-term capital gain or loss if the Quanex stockholder’s holding period in the shares of Quanex common stock immediately prior to the spin-off is more than one year. The amount and character of gain or loss must be calculated separately for each identifiable block of shares of Quanex common stock surrendered.
 
See “Material U.S. Federal Income Tax Consequences” beginning on page 29 for a detailed discussion of the U.S. federal income tax treatment of the spin-off and merger, including a discussion of possible alternative treatments.
 
Tax matters are very complicated and the tax consequences of the merger to any particular Quanex stockholder will depend on that stockholder’s particular situation. Quanex stockholders should consult with their own tax advisors to determine the specific tax consequences of the merger to them.
 
Recommendation of the Quanex Board of Directors (page 21)
 
The Quanex Board of Directors has unanimously determined that the merger is advisable and in your best interests and unanimously recommends that you vote “FOR” approval and adoption of the merger agreement and the transactions contemplated thereby and any adjournment or postponement of the special meeting.
 
Opinion of Lazard Frères & Co. LLC — Financial Advisor to Quanex (page 21)
 
In connection with the proposed merger, Quanex’s financial advisor, Lazard Frères & Co. LLC, delivered to Quanex’s Board of Directors a written opinion, dated November 18, 2007, as to the fairness, from a financial point of view, to the holders of Quanex common stock of the merger consideration. The full text of Lazard’s written opinion is attached to this proxy statement as Annex B. We encourage you to read that opinion carefully in its entirety for a description of the procedures followed, assumptions made, matters

Table of Contents

considered, and limitations on the review undertaken by Lazard in rendering its opinion. Lazard’s opinion was provided for the use and benefit of Quanex’s Board of Directors in connection with its evaluation of the merger and does not address the merits of the proposed merger or constitute a recommendation to any stockholder as to how he or she should vote on the merger or any matter relevant to the merger agreement. The opinion addresses only the fairness, from a financial point of view, as of the date of the opinion, of the merger consideration to be paid to holders of shares of Quanex common stock (other than holders of dissenters’ shares and shares of Quanex common stock owned directly by Quanex as treasury stock or by Gerdau or Gerdau Delaware, and in each case not held on behalf of third parties).
 
Interests of Quanex Directors and Executive Officers in the Merger (page 33)
 
When you consider the recommendation of Quanex’s Board of Directors that you vote for the approval and adoption of the merger agreement, you should be aware that certain of our directors and executive officers may have interests in the merger that are different from, or in addition to, yours. The Quanex Board of Directors was aware of these interests and considered them, among other matters, in unanimously approving and adopting the merger agreement and unanimously recommending that Quanex stockholders vote to approve and adopt the merger agreement. At the close of business on the record date for the Quanex special meeting, directors and executive officers of Quanex and their affiliates will be entitled to vote approximately     % of the shares of Quanex common stock outstanding on that date.
 
Conditions to Completion of the Merger (page 44)
 
Completion of the merger depends on a number of conditions being satisfied or waived. These conditions include the following:
 
  •  the approval of Quanex’s stockholders will have been obtained;
 
  •  the waiting period applicable to the consummation of the merger under applicable antitrust laws will have expired or have terminated and any other approvals from governmental entities will have been obtained;
 
  •  there is no judgment, injunction or other order in effect that restrains, enjoins or otherwise prohibits consummation of the merger or the other transactions contemplated by the merger agreement;
 
  •  the representations and warranties of the parties contained in the merger agreement will be true and correct as of the date of the merger agreement and as of the effective time of the merger in the manner described under the caption “The Merger Agreement — Conditions to Completion of the Merger”;
 
  •  the parties will have performed in all material respects their respective obligations under the merger agreement at or prior to the closing date; and
 
  •  with respect to the obligations of Gerdau and Gerdau Delaware only, the spin-off will have been effected by Quanex.
 
Regulatory Matters (page 26)
 
Under the Hart-Scott-Rodino Act, the parties cannot complete the merger until they have notified and furnished information to the Federal Trade Commission (“FTC”) and the Antitrust Division of the United States Department of Justice (“DOJ”), and specified waiting periods expire or are terminated. On November 30, 2007, Quanex and Gerdau submitted the notification filings to the FTC and the DOJ. The waiting period under the Hart-Scott-Rodino Act will expire on December 31, 2007, unless each party receives early termination of the waiting period before that time or unless the reviewing agency extends the period by requesting additional information.
 
A party or parties to a transaction may, but are not required to, submit to the Committee on Foreign Investment in the United States, which we refer to as CFIUS, in accordance with the regulations implementing Section 721 of the Defense Production Act of 1950, as amended, a voluntary notice of the transaction. Section 721 empowers the President of the United States to prohibit or suspend an acquisition of, or


4


Table of Contents

investment in, a U.S. company by a “foreign person” if the President of the United States, after investigation, finds credible evidence that the foreign person might take action that threatens to impair the national security of the United States and that other provisions of existing law, other than the International Emergency Economic Powers Act, do not provide adequate and appropriate authority to protect the national security. CFIUS has the authority to receive notices of proposed transactions, determine when an investigation is warranted, conduct investigations and submit recommendations to the President of the United States to suspend or prohibit the completion of transactions or to require divestitures of completed transactions.
 
On          , 200 , the parties submitted a notice of the transaction to CFIUS. CFIUS has 30 calendar days from the date of submission to decide whether to initiate an investigation. If CFIUS declines to investigate, it sends a letter advising the parties that CFIUS has determined not to conduct an investigation and that CFIUS has concluded its review of the transaction, and the review process is complete. If CFIUS decides to investigate, it has 45 calendar days in which to prepare a recommendation to the President of the United States, who must then decide within 15 calendar days whether to block the transaction or, in the case of a completed transaction, seek a divestiture.
 
Although Quanex and Gerdau do not believe an investigation of, or recommendation to block, the merger by CFIUS is warranted under the standards of Section 721, CFIUS and the President of the United States have considerable discretion to conduct investigations and block transactions under Section 721.
 
Termination of the Merger Agreement (page 46)
 
Before the effective time of the merger, the merger agreement may be terminated by either party under certain circumstances specified in the merger agreement, including after a termination date of April 30, 2008, due to the breach by the other party of any of its representations, warranties, covenants or agreements in the merger agreement, under certain circumstances if the approval of Quanex’s stockholders is not obtained or if Quanex receives and accepts a superior proposal to the merger.
 
Non-Solicitation Provisions and Acquisition Proposals (page 41)
 
Subject to certain conditions, until the effective time of the merger, Quanex is not permitted to solicit or seek acquisition proposals, engage in any substantive discussions regarding such proposals, provide any information to third parties regarding such proposals, enter into any agreement relating to any such proposals or release any third party from, or waive any provision of, any confidentiality or standstill agreement relating to any such proposals. However, under certain circumstances, if Quanex receives an unsolicited takeover proposal from a third party that Quanex’s Board of Directors determines in good faith (after consultation with outside counsel and financial advisors) constitutes a superior proposal or would reasonably be expected to lead to a superior proposal, Quanex may furnish nonpublic information to that third party and engage in negotiations regarding a takeover proposal with that third party, subject to specified conditions set forth in the merger agreement.
 
Fees and Expenses (page 46)
 
If Quanex terminates the merger agreement, Quanex must pay to Gerdau, in certain circumstances set forth in the merger agreement, $50,190,000. Gerdau must pay Quanex a termination fee of $60 million if the merger agreement is terminated in certain circumstances set forth in the merger agreement following a second request made by the FTC or the DOJ under the Hart-Scott-Rodino Act.
 
Whether or not the merger is consummated, each of Gerdau, Gerdau Delaware and Quanex will bear its own fees and expenses in connection with the merger agreement.
 
Appraisal Rights (page 27)
 
Under Delaware law, you are entitled to appraisal rights in connection with the merger. As a result, you will have the right under Delaware law to have the “fair value” of your Quanex common stock determined by


5


Table of Contents

the Delaware Chancery Court. This right to appraisal is subject to a number of restrictions and procedural requirements. Generally, in order to exercise your appraisal rights, you must:
 
  •  Send a written demand to Quanex for appraisal in compliance with the DGCL before the vote on the adoption of the merger agreement;
 
  •  Not vote in favor of the adoption of the merger agreement; and
 
  •  Continuously hold your Quanex common stock from the date you make the demand for appraisal through the effective date of the merger.
 
Merely voting against the adoption of the merger agreement will not protect your rights to an appraisal, which requires you to take all the steps provided under Delaware law. Delaware law requirements for exercising appraisal rights are described in further detail in this proxy statement. In addition, Section 262 of the DGCL, which is the section of Delaware law regarding appraisal rights, is set forth in Annex C to this proxy statement.
 
Market Price of Our Common Stock (page 46)
 
Our shares of common stock are traded on the NYSE under the ticker symbol “NX.” On November 16, 2007, the last trading day prior to the date of the public announcement of the merger agreement, the closing price of our common stock on the NYSE was $36.74 per share. On January   , 2008, the last trading day prior to the date of this proxy statement, the closing price of our common stock on the NYSE was $      per share. You are encouraged to obtain current market quotations for shares of our common stock.

We cannot complete the merger unless, among other things, Quanex’s stockholders vote to approve and adopt the merger agreement.
 
Q3: What am I voting on?
 
A3: Quanex is proposing to merge with Gerdau Delaware, with Quanex becoming a wholly-owned subsidiary of Gerdau. Quanex stockholders are being asked to vote to approve and adopt the merger agreement. Quanex is also seeking your approval of a proposal to adjourn or postpone the special meeting, if necessary, to solicit additional proxies in favor of approval and adoption of the merger agreement.
 
Q4: What will I receive in exchange for my Quanex shares?
 
A4: Upon completion of the merger, you will receive $39.20 in cash, without interest, for each share of Quanex common stock that you own. The merger consideration is not subject to any adjustment.
 
In connection with the merger, Quanex stockholders will receive, pursuant to the spin-off of Quanex’s Building Products Group, one share of Quanex Building Products common stock for each share of Quanex common stock that they own on the record date of the spin-off, which will be the same date as the closing date of the merger.
 
Q5: What will I receive in exchange for my options to purchase Quanex common stock and my restricted stock units?
 
A5: At the effective time of the merger, Quanex stock options will become vested and exercisable and will be cancelled. If you hold Quanex stock options, you will be entitled to receive an amount in cash equal to: (x) the total number of shares of Quanex common stock subject to the stock option times (y) the excess of (i) the sum of (A) $39.20 and (B) the closing sales price of a share of Quanex Building Products common stock on the NYSE on the distribution date for the spin-off of Quanex’s Building Products Group over (ii) the exercise price per share under the stock option, less any applicable withholding.
 
Each restricted stock unit that has been issued but has not vested prior to the effective time of the merger will become fully vested at the effective time of the merger. If you hold Quanex restricted stock units, you will have the right to receive an amount per restricted stock unit equal to the sum of (y) $39.20 and (z) the closing sales price of a share of Quanex Building Products common stock on the NYSE on the distribution date for the spin-off of Quanex’s Building Products Group.

Q6: What is the required vote to approve and authorize the merger?
 
A6: Holders of a majority of the outstanding shares of Quanex common stock entitled to vote at the special meeting must vote to approve and adopt the merger agreement to complete the merger. Approval of any adjournments of the special meeting to solicit additional proxies requires the affirmative vote of a majority of the outstanding shares of Quanex common stock present in person or by proxy at the special meeting and entitled to vote on the matter.
 
If a quorum is not present at the special meeting, the special meeting may be adjourned by the vote of a majority of the outstanding shares of Quanex common stock entitled to vote at the special meeting and present in person or by proxy.
 
Even if the votes set forth above are obtained at the special meeting, we cannot assure you that the merger will be completed, because the completion of the merger is subject to the satisfaction or waiver of other conditions discussed in this proxy statement, including the completion of the spin-off.
 
Q7: What happens if I do not vote?
 
A7: Because the required vote of Quanex stockholders is based upon the number of outstanding shares of Quanex common stock entitled to vote rather than upon the number of shares actually voted, abstentions from voting and “broker non-votes” will have the same effect as a vote “AGAINST” approval and adoption of the merger agreement. If you return a properly signed proxy card but do not indicate how you want to vote, your proxy will be counted as a vote “FOR” approval and adoption of the merger agreement and “FOR” approval of any proposal to adjourn or postpone the special meeting to solicit additional proxies in favor of approval and adoption of the merger agreement.
 
Q8: How does the Quanex Board of Directors recommend I vote?
 
A8: The Board of Directors of Quanex unanimously recommends that Quanex’s stockholders vote “FOR” approval and adoption of the merger agreement and “FOR” the approval of any proposal to adjourn or postpone the special meeting to solicit additional proxies in favor of approval and adoption of the merger agreement. The Board of Directors of Quanex believes the merger is advisable and in the best interests of Quanex and its stockholders.
 
Q9: Do I have appraisal rights with respect to the merger?
 
A9: Yes. Under Delaware law, a Quanex stockholder has the right to dissent from the merger and, in lieu of receiving the merger consideration, obtain payment in cash of the fair value of his or her shares of Quanex common stock as determined by the Delaware Chancery Court. To exercise appraisal rights, a Quanex stockholder must strictly follow the procedures prescribed by Section 262 of the DGCL. See “The Merger — Appraisal Rights” beginning on page 27 of this proxy statement. In addition, the full text of the applicable provisions of Delaware law is included as Annex C to this proxy statement.
 
Q10: When do you expect the merger to be completed?
 
A10: We are working on completing the merger as quickly as possible. To complete the merger, we must obtain the approval of the Quanex stockholders and satisfy or waive all other closing conditions under the merger agreement, which we currently expect should occur in the first calendar quarter of 2008. However, we cannot assure you when or if the merger will occur. See “The Merger Agreement — Conditions to the Merger” beginning on page 44 of this proxy statement. If the merger occurs, we will promptly make a public announcement of that fact.
 
Q11: What will happen to my Quanex shares after completion of the merger?
 
A11: Upon completion of the merger, your shares of Quanex common stock will be canceled and will represent only the right to receive $39.20 per share as the merger consideration (or the fair value of your Quanex common stock if you seek appraisal rights) and any declared but unpaid dividends that you may be owed. In addition, trading in shares of Quanex common stock on the NYSE will cease and price quotations for shares of Quanex common stock will no longer be available.

In connection with the spin-off of Quanex’s Building Products Group, Quanex stockholders will also receive one share of Quanex Building Products common stock for each share of Quanex common stock that they own on the record date of the spin-off, which will be the same date as the closing date of the merger.
 
Q12: How does the merger consideration compare to the market price of the shares of Quanex common stock?
 
A12: The merger consideration is $39.20 per share of Quanex common stock, without interest. On November 16, 2007, the last trading day prior to the date of the public announcement of the merger agreement, the closing price of our common stock on the NYSE was $36.74 per share. On January   , 2008, the last trading day prior to the date of this proxy statement, the closing price of our common stock on the NYSE was $per share. In making this comparison, you should keep in mind that, as a result of the spin-off, you will also receive one share of Quanex Building Products common stock for each share of Quanex common stock that you hold on the record date for the spin-off, which will be the same date as the closing date of the merger.
 
Q13: What happens if the merger is not completed?
 
A13: Quanex will consider its options with respect to alternative transactions for the Building Products Group and the Vehicular Products Group and may still proceed with the spin-off of the Building Products Group.
 
About the Spin-Off
 
Q14: What is the spin-off transaction being contemplated by Quanex?
 
A14: Immediately prior to and in connection with the merger, Quanex will spin-off to its stockholders the limited liability company interests of its building products subsidiary containing all of the assets and liabilities of Quanex’s Building Products Group known as Quanex Building Products LLC. The interests will be distributed to Quanex’s stockholders on the basis of one unit of Quanex Building Products LLC for each share of Quanex common stock outstanding. Immediately following the spin-off, Quanex Building Products LLC will merge with and into its wholly-owned subsidiary Quanex Building Products Corporation, with Quanex Building Products Corporation being the surviving company in the merger. Each unit of Quanex Building Products LLC will be converted immediately into one share of Quanex Building Products Corporation common stock. As a result, a Quanex stockholder will receive one share of Quanex Building Products Corporation common stock for each share of Quanex common stock held by such stockholder.
 
Quanex stockholder approval is not needed for, and you are not being asked for a proxy in relation to, the proposed spin-off of the Building Products Group of Quanex or the subsequent merger of Quanex Building Products LLC with and into Quanex Building Products Corporation. Holders of Quanex common stock on the record date of the spin-off, which will be the same date as the closing date of the merger, will receive an information statement describing their ownership of Quanex Building Products Corporation.
 
About Voting at the Special Meeting
 
Q15: Who is entitled to vote at the special meeting?
 
A15: Holders of record of Quanex common stock at the close of business on January   , 2008, which is the date Quanex’s Board of Directors has fixed as the record date for the special meeting, are entitled to receive notice of and vote at the special meeting.
 
Q16: What is a quorum?
 
A16: A quorum is the number of shares that must be present to hold the meeting. The quorum requirement for the Quanex special meeting is the holders of a majority of the issued and outstanding shares of Quanex common stock as of the record date, present in person or represented by proxy and entitled to vote

Table of Contents

at the special meeting. A proxy submitted by a stockholder may indicate that all or a portion of the shares represented by the proxy are not being voted with respect to a particular matter. Proxies that are marked “abstain” or for which votes have otherwise been withheld and proxies relating to “street name” shares that are returned to Quanex but not voted will be treated as shares present for purposes of determining the presence of a quorum on all matters.
 
Q17: How many shares can vote?
 
A17: On the record date, Quanex had outstanding           shares of common stock, which constitute Quanex’s only outstanding voting securities. Each Quanex stockholder is entitled to one vote on each proposal for each share of Quanex common stock held as of the record date.
 
Q18: What do I need to do now?
 
A18: After carefully reading and considering the information contained and referred to in this proxy statement, including its annexes, please authorize your shares of Quanex common stock to be voted by returning your completed, dated, and signed proxy card in the enclosed return envelope, or vote by telephone or Internet, as soon as possible. To be sure that your vote is counted, please submit your proxy as instructed on your proxy card even if you plan to attend the special meeting in person. DO NOT enclose or return your stock certificates with your proxy card. If you hold shares registered in the name of a broker, bank, or other nominee, that broker, bank, or other nominee has enclosed or will provide a voting instruction card for use in directing your broker, bank, or other nominee how to vote the shares.
 
Q19: May I vote in person?
 
A19: Yes. You may attend the special meeting of Quanex’s stockholders and vote your shares in person rather than by signing and returning your proxy card. If you wish to vote in person and your shares are held by a broker, bank, or other nominee, you need to obtain a proxy from the broker, bank, or nominee authorizing you to vote your shares held in the broker’s, bank’s, or nominee’s name
 
Q20: If my shares are held in “street name,” will my broker, bank, or other nominee vote my shares for me?
 
A20: Yes, but your broker, bank, or other nominee may vote your shares of Quanex common stock only if you instruct your broker, bank, or other nominee how to vote. If you do not provide your broker, bank, or other nominee with instructions on how to vote your “street name” shares, your broker, bank, or other nominee will not be permitted to vote them on the merger. You should follow the directions your broker, bank, or other nominee provides to ensure your shares are voted at the special meeting. Please check the voting form used by your broker, bank, or other nominee to see if it offers telephone or Internet voting.
 
Q21: May I change my vote?
 
A21: Yes. You may change your vote at any time before your proxy is voted at the special meeting. If your Quanex common stock is registered in your own name, you can do this in one of three ways.
 
• First, you can deliver to Quanex, prior to the special meeting, a written notice stating that you want to revoke your proxy. The notice should be sent to the attention of Kevin P. Delaney, Secretary, Quanex Corporation, 1900 West Loop South, Suite 1500, Houston, Texas 77027, to arrive by the close of business on February   , 2008.
 
• Second, prior to the special meeting, you can complete and deliver a new proxy card. The proxy card should be sent to the addressee indicated on the pre-addressed envelope enclosed with your initial proxy card to arrive by the close of business on February   , 2008. The latest dated and signed proxy actually received by this addressee before the special meeting will be counted, and any earlier proxies will be considered revoked. If you vote electronically through the Internet or by telephone, you can change your vote by submitting a different vote through the Internet or by telephone, in which case your later-submitted proxy will be recorded and your earlier proxy revoked.


10


Table of Contents

 
• Third, you can attend the Quanex special meeting and vote in person. Any earlier proxy will thereby be revoked automatically. Simply attending the special meeting, however, will not revoke your proxy, as you must vote at the special meeting to revoke a prior proxy.
 
If you have instructed a broker, bank or nominee to vote your shares, you must follow directions you receive from your broker to change or revoke your vote.
 
If you are a street-name stockholder and you vote by proxy, you may later revoke your proxy instructions by informing the holder of record in accordance with that entity’s procedures.
 
Q22: How will the proxies vote on any other business brought up at the special meetings?
 
A22: By submitting your proxy, you authorize the persons named on the proxy card to use their judgment to determine how to vote on any other matter properly brought before the special meeting. The proxies will vote your shares in accordance with your instructions. If you sign, date, and return your proxy without giving specific voting instructions, the proxies will vote your shares “FOR” the proposal. If you do not return your proxy, or if your shares are held in street name and you do not instruct your bank, broker or nominee on how to vote, your shares will not be voted at the special meeting.
 
The Quanex Board of Directors does not intend to bring any other business before the meeting, and it is not aware that anyone else intends to do so. If any other business properly comes before the meeting, it is the intention of the persons named on the proxy cards to vote as proxies in accordance with their best judgment.
 
Q23: What is a broker non-vote?
 
A23: A “broker non-vote” occurs when a bank, broker, or other nominee submits a proxy that indicates that the broker does not vote for some or all of the proposals because the broker has not received instructions from the beneficial owners on how to vote on these proposals and does not have discretionary authority to vote in the absence of instructions.
 
Q24: Will broker non-votes or abstentions affect the results?
 
A24: Yes. Broker non-votes or abstentions will have the same effect as a vote against the proposal to adopt the merger agreement, but will have no effect on the outcome of the proposal relating to adjournments or postponements of the special meeting, if necessary, to permit further solicitation of proxies. If your shares are held in street name, we urge you to instruct your bank, broker, or nominee how to vote your shares for those proposals on which you are entitled to vote.
 
Q25: What happens if I choose not to submit a proxy or to vote?
 
A25: If you do not submit a proxy or vote at the Quanex special meeting, it will have the same effect as a vote against the proposal to adopt the merger agreement, but will have no effect on the outcome of the proposal relating to adjournments or postponements of the special meeting, if necessary, to permit further solicitations of proxies.
 
Q26: Why is it important for me to vote?
 
A26: We cannot complete the merger without holders of a majority of the outstanding Quanex common stock present in person or by proxy at the special meeting voting in favor of the approval and adoption of the merger agreement.
 
Q27: What happens if I sell my shares of Quanex common stock before the special meeting?
 
A27: The record date for the special meeting is January   , 2008, which is earlier than the date of the special meeting. If you hold your shares of Quanex common stock on the record date you will retain your right to vote at the special meeting. If you transfer your shares of Quanex common stock after the record date but prior to the date on which the merger is completed, you will continue to have the right to vote at the special meeting but you will lose the right to receive the merger consideration for shares of Quanex

Table of Contents

common stock. The right to receive the merger consideration will pass to the person who owns your shares of Quanex common stock when the merger is completed.
 
General
 
Q28: Should I send in my Quanex stock certificates now?
 
A28: No. PLEASE DO NOT SEND ANY STOCK CERTIFICATES WITH YOUR PROXY CARD. After the merger is completed, you will receive written instructions informing you how to send in your stock certificates to receive the merger consideration.
 
Q29: What does it mean if I get more than one proxy card?
 
A29: Your shares of Quanex common stock are probably registered in more than one account. You should vote each proxy card you receive.
 
Q30: Where can I find more information about the special meeting, the merger or Quanex?
 
A30: You can find more information about Quanex in its filings with the Securities and Exchange Commission and the NYSE. If you have any questions about the special meeting, the merger or how to submit your proxy, or if you need additional copies of this proxy statement or the enclosed proxy card or voting instructions, you should contact Quanex at the address or phone number below. If your broker holds your shares, you can also call your broker for additional information.

INFORMATION ABOUT THE SPECIAL MEETING AND VOTING
 
This proxy statement is being furnished to Quanex stockholders by Quanex’s Board of Directors in connection with the solicitation of proxies from the holders of Quanex common stock for use at the special meeting of Quanex stockholders and any adjournments or postponements of the special meeting.
 
Date, Time and Place
 
The special meeting of stockholders of Quanex will be held on February   , 2008 at :00 a.m., at the Company’s principal executive offices at 1900 West Loop South, 15th Floor, Houston, Texas.
 
Matters to Be Considered
 
At the special meeting, Quanex stockholders will be asked:
 
  •  to consider and vote upon a proposal to approve and adopt the merger agreement;
 
  •  to consider and vote upon a proposal to adjourn or postpone the special meeting, if necessary, to solicit additional proxies in favor of the approval and adoption of the merger agreement; and
 
  •  to consider and transact any other business as may properly be brought before the special meeting or any adjournments or postponements thereof.
 
At this time, the Quanex Board of Directors is unaware of any matters, other than those set forth above, that it expects to properly come before the special meeting.
 
Stockholders Entitled to Vote
 
The close of business on January   , 2008 has been fixed by Quanex’s Board as the record date for the determination of those holders of Quanex common stock who are entitled to notice of, and to vote at, the special meeting and on any adjournments or postponements thereof. At the close of business on the record date, there were           shares of Quanex common stock outstanding and entitled to vote, held by approximately           holders of record. A list of the stockholders of record entitled to vote at the special meeting will be available for examination by Quanex stockholders for any purpose germane to the meeting. The list will be available at the meeting and for ten days prior to the meeting during ordinary business hours by contacting Quanex’s Secretary at 1900 West Loop South, Suite 1500, Houston, Texas 77027.
 
Quorum and Required Vote
 
Each holder of record of Quanex common stock as of the record date is entitled to cast one vote per share at the special meeting on each proposal. The presence, in person or by proxy, of the holders of a majority of the issued and outstanding shares of Quanex common stock outstanding as of the record date constitutes a quorum for the transaction of business at the special meeting. The affirmative vote of the holders of a majority of the shares of Quanex common stock entitled to vote at the special meeting is required to approve and adopt the merger agreement.
 
As of the record date for the special meeting, directors and executive officers of Quanex and their affiliates beneficially owned an aggregate of      shares of Quanex common stock entitled to vote at the special meeting. These shares represent approximately     % of the Quanex common stock outstanding and entitled to vote as of the record date.
 
As of the record date, Gerdau and its directors, executive officers, and their affiliates owned none of the outstanding shares of Quanex common stock.
 
How Shares Will Be Voted at the Special Meeting
 
All shares of Quanex common stock represented by properly executed proxies received before or at the special meeting, and not properly revoked, will be voted as specified in the proxies. Properly executed proxies


13


Table of Contents

that do not contain voting instructions will be voted “FOR” approval and adoption of the merger agreement and any adjournment or postponement of the special meeting.
 
A properly executed proxy marked “Abstain” with respect to any proposal will be counted as present for purposes of determining whether there is a quorum at the special meeting. However, because the approval and adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares entitled to vote at the special meeting, an abstention will have the same effect as a vote “AGAINST” approval and adoption of the merger agreement.
 
If you hold shares of Quanex common stock in “street name” through a bank, broker, or other nominee, the bank, broker, or nominee may vote your shares only in accordance with your instructions. If you do not give specific instructions to your bank, broker, or nominee as to how you want your shares voted, your bank, broker, or nominee will indicate that it does not have authority to vote on the proposal, which will result in what is called a “broker non-vote.” Broker non-votes will be counted for purposes of determining whether there is a quorum present at the special meeting, but because approval and adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares entitled to vote at the special meeting, broker non-votes will have the same effect as a vote “AGAINST” approval and adoption of the merger agreement.
 
If any other matters are properly brought before the special meeting, the proxies named in the proxy card will vote the shares represented by duly executed proxies in their sole discretion.
 
How to Vote Your Shares
 
Record holders may cause their shares of Quanex common stock to be voted using one of the following methods:
 
  •  mark, sign, date and return the enclosed proxy card by mail;
 
  •  submit your proxy or voting instructions by telephone or Internet by following the instructions included with your proxy card; or
 
  •  appear and vote in person by ballot at the special meeting.
 
Regardless of whether you plan to attend the special meeting, we request that you complete and return a proxy for your shares of Quanex common stock as described above as promptly as possible. You can always change your vote at the special meeting. If you properly submit your proxy card or your voting instructions as described above, one of the individuals named as your proxy will vote your shares of Quanex common stock as you have directed. You may vote for or against the proposals submitted at the special meeting or you may abstain from voting.
 
If you hold shares of Quanex common stock through a broker, bank, or other nominee, please follow the voting instructions provided by that firm. If you do not return your proxy card, or if your shares are held in a stock brokerage account or held by a bank, broker, or other nominee, or, in other words, in “street name” and you do not instruct your bank, broker, or other nominee on how to vote those shares, those shares will not be voted at the special meeting.
 
A number of banks and brokerage firms participate in a program that also permits stockholders whose shares are held in “street name” to direct their vote by the Internet or telephone. This option, if available, will be reflected in the voting instructions from the bank or brokerage firm that accompany this proxy statement. If your shares are held in an account at a bank or brokerage firm that participates in such a program, you may direct the vote of these shares by the Internet or telephone by following the voting instructions enclosed with the proxy from the bank or brokerage firm. The Internet and telephone proxy procedures are designed to authenticate stockholders’ identities, to allow stockholders to give their proxy voting instructions and to confirm that those instructions have been properly recorded. Votes directed by the Internet or telephone through such a program must be received by 11:59 p.m., New York, New York time, on February   , 2008. Requesting a proxy prior to the deadline described above will automatically cancel any voting directions you have previously given by the Internet or telephone with respect to your shares. Directing the voting of your


14


Table of Contents

shares will not affect your right to vote in person if you decide to attend the meeting; however, you must first obtain a signed and properly executed proxy from your bank, broker, or other nominee to vote your shares held in street name at the special meeting.
 
If you submit your proxy but do not make specific choices, your proxy will be voted “FOR” each of the proposals presented.
 
How to Change Your Vote
 
If you are a registered stockholder, you may revoke your proxy at any time before the shares are voted at the special meeting by:
 
  •  completing, signing, and timely submitting a new proxy to the addressee indicated on the pre-addressed envelope enclosed with your initial proxy card by the close of business on February   , 2008; the latest dated and signed proxy actually received by such addressee before the special meeting will be counted, and any earlier proxies will be considered revoked;
 
  •  notifying Quanex’s Secretary at 1900 West Loop South, Suite 1500, Houston, Texas 77027, Attn: Kevin P. Delaney, in writing, by the close of business on February   , 2008, that you have revoked your earlier proxy; or
 
  •  voting in person at the special meeting.
 
Merely attending the special meeting will not revoke any prior votes or proxies; you must vote at the special meeting to revoke a prior proxy.
 
If you hold shares of Quanex common stock through a bank, broker or other nominee and you vote by proxy, you may later revoke your proxy instructions by informing the holder of record in accordance with that firm’s procedures.
 
Solicitation of Proxies
 
In addition to solicitation by mail, directors, officers, and employees of Quanex may solicit proxies for the special meeting from Quanex stockholders personally or by telephone, facsimile, and other electronic means without compensation other than reimbursement for their actual expenses.
 
Arrangements will be made with brokerage firms and other custodians, nominees, and fiduciaries for the forwarding of solicitation material to the beneficial owners of Quanex common stock held of record by those persons, and Quanex will, if requested, reimburse the record holders for their reasonable out-of-pocket expenses in so doing.
 
Quanex has engaged D.F. King & Co., Inc. to assist in the solicitation of proxies and provide related advice and informational support for a services fee and the reimbursement of customary disbursements that are not expected to exceed $12,000 in the aggregate.
 
Recommendation of the Quanex Board of Directors
 
The Quanex Board of Directors has unanimously approved the merger agreement and the transactions contemplated by the merger agreement, including the merger. The Quanex Board of Directors determined that the merger is advisable and in the best interests of Quanex and its stockholders and unanimously recommends that you vote “FOR” approval and adoption of the merger agreement. See “The Merger — Quanex’s Reasons for the Merger” beginning on page 20 and “The Merger — Recommendation of the Quanex Board of Directors” beginning on page 21 for a more detailed discussion of the recommendation of the Quanex Board of Directors.
 
Special Meeting Admission
 
If you wish to attend the special meeting in person, you must present a form of personal identification and proof of ownership. If you are a beneficial owner of shares of Quanex common stock that is held by a


15


Table of Contents

bank, broker, or other nominee, you will need proof of such beneficial ownership of such shares to be admitted to the meeting. A recent brokerage statement or a letter from your bank or broker are examples of proof of ownership.
 
No cameras, recording equipment, electronic devices, large bags, briefcases, or packages will be permitted in the meeting.
 
PLEASE DO NOT SEND IN ANY QUANEX COMMON STOCK CERTIFICATES WITH YOUR PROXY CARD. After the merger is completed, you will receive written instructions from the exchange agent informing you how to surrender your stock certificates to receive the merger consideration.
 
Adjournment and Postponements
 
The special meeting may be adjourned from time to time, to reconvene at the same or some other place, by approval of the holders of shares of Quanex common stock representing a majority of the votes present in person or by proxy at the special meeting, whether or not a quorum exists, without further notice other than by an announcement made at the special meeting, so long as the new time and place for the special meeting are announced at that time. If the adjournment is for more than thirty days, or if after the adjournment a new record date is determined for the adjourned special meeting, a notice of the adjourned special meeting must be given to each stockholder of record entitled to vote at the special meeting. If a quorum is not present at the Quanex special meeting, holders of shares of Quanex common stock may be asked to vote on a proposal to adjourn or postpone the Quanex special meeting to solicit additional proxies. If a quorum is not present at the Quanex special meeting, the holders of a majority of the shares entitled to vote who are present in person or by proxy may adjourn the meeting. If a quorum is present at the Quanex special meeting but there are not sufficient votes at the time of the special meeting to approve the other proposal(s), holders of shares of Quanex common stock may also be asked to vote on a proposal to approve the adjournment or postponement of the special meeting to permit further solicitation of proxies.
 
Appraisal Rights
 
Under Delaware law, if you do not vote in favor of adopting the merger agreement, you will have the right to have the “fair value” of your shares of our common stock determined by the Court of Chancery of the State of Delaware and to receive payment based on that valuation in lieu of receiving the merger consideration, but only if you comply with all requirements of Delaware law, which are summarized in this proxy statement. The ultimate amount that you receive as a dissenting stockholder in an appraisal proceeding may be more than, less than, or the same as, the $39.20 per share you would have received under the merger agreement. If you intend to exercise appraisal rights, among other things, you must:
 
  •  send a written demand to us for appraisal in compliance with Delaware law before the vote on adopting the merger agreement at the special meeting;
 
  •  not vote for the proposal to adopt the merger agreement; and
 
  •  continuously hold your shares of our common stock from the date you make the demand for appraisal through the effective date of the merger.
 
If you vote for the proposal to adopt the merger agreement, you will waive your rights to seek appraisal of your shares of our common stock under Delaware law. Also, merely voting against or abstaining with respect to the proposal to adopt the merger agreement will not protect your rights to an appraisal. Failure to follow exactly the procedures specified under Delaware law will result in the loss of your appraisal rights. Delaware law requirements for exercising appraisal rights are described in further detail in “Appraisal Rights” beginning on page 27 and the relevant section of Delaware law regarding appraisal rights is reproduced and attached as Annex C to this proxy statement.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
 
Certain of the statements contained in this proxy statement are “forward-looking” statements as defined under the Private Securities Litigation Reform Act of 1995. Generally, the words “expect,” “believe,” “intend,” “estimate,” “anticipate,” “project,” “will” and similar expressions identify forward-looking statements, which generally are not historical in nature. All statements which address future operating performance, events or developments that we expect or anticipate will occur in the future, including statements relating to volume, sales, operating income and earnings per share, and statements expressing a general outlook about future operating results, are forward-looking statements. Forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from Quanex’s historical experience and our present projections or expectations. As and when made, management believes that these forward-looking statements are reasonable. However, caution should be taken not to place undue reliance on any such forward-looking statements since such statements speak only as of the date when made and there can be no assurance that such forward-looking statements will occur. Quanex undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
 
Factors exist that could cause Quanex’s actual results to differ materially from the expected results described in or underlying Quanex’s forward-looking statements. Such factors include domestic and international economic activity, prevailing prices of steel and aluminum scrap and other raw material costs, the rate of change in prices for steel and aluminum scrap, energy costs, interest rates, construction delays, market conditions, particularly in the vehicular, home building and remodeling markets, any material changes in purchases by Quanex’s principal customers, labor supply and relations, environmental regulations, changes in estimates of costs for known environmental remediation projects and situations, world-wide political stability and economic growth, Quanex’s successful implementation of its internal operating plans, acquisition strategies and integration, performance issues with key customers, suppliers and subcontractors, and regulatory changes and legal proceedings. Accordingly, there can be no assurance that the forward-looking statements contained herein will occur or that objectives will be achieved. All written and verbal forward-looking statements attributable to Quanex or persons acting on its behalf are expressly qualified in their entirety by such factors.
 
THE SPIN-OFF
 
Immediately prior to and in connection with the merger, Quanex will spin-off to its stockholders the limited liability company interests of its building products subsidiary containing all of the assets and liabilities of Quanex’s Building Products Group known as Quanex Building Products LLC. The interests will be distributed to Quanex’s stockholders on the basis of one unit of Quanex Building Products LLC for each share of Quanex common stock outstanding. Immediately following the spin-off, Quanex Building Products LLC will merge with and into its wholly-owned subsidiary Quanex Building Products Corporation, with Quanex Building Products Corporation being the surviving company in the merger. Each unit of Quanex Building Products LLC will be converted immediately into one share of Quanex Building Products Corporation common stock. As a result, a Quanex stockholder will receive one share of Quanex Building Products Corporation common stock for each share of Quanex common stock held by such stockholder.
 
Quanex stockholder approval is not needed for, and you are not being asked for a proxy in relation to, the proposed spin-off of the Building Products Group of Quanex or the subsequent merger of Quanex Building Products LLC with and into Quanex Building Products Corporation. Holders of Quanex common stock on the record date of the spin-off, which will be the same date as the closing date of the merger, will receive an information statement describing their ownership of Quanex Building Products Corporation.

THE MERGER
 
General
 
Quanex’s Board of Directors is using this document to solicit proxies from the holders of Quanex common stock for use at the Quanex special meeting, at which holders of Quanex common stock will be asked to vote upon approval and adoption of the merger agreement.
 
The Board of Directors of Quanex has unanimously approved the merger agreement providing for the merger of Gerdau Delaware with and into Quanex. Upon the completion of the merger, the separate corporate existence of Gerdau Delaware will terminate and Quanex will be a wholly-owned subsidiary of Gerdau. Subject to the satisfaction or waiver of the conditions to closing of the merger, including the completion of the spin-off, we expect to complete the merger in the first calendar quarter of 2008.
 
Background of the Merger
 
Since early 2006 the management and Board of Directors of Quanex had been debating and exploring the merits of alternative strategies involving the separation of its Building Products Group from its Vehicular Products Group. Ultimately, management and the Board of Directors determined that each Group would be better positioned to grow separate from each other and would receive a better valuation in the marketplace and, as a result, would deliver enhanced value to stockholders.
 
In July 2006, Quanex began active discussions with its financial and legal advisors regarding a potential tax free spin-off of the Building Products Group as an initial step towards delivering value to stockholders, given Quanex’s relatively low market valuation compared to other public companies active in the building products sector. At a meeting of the Quanex Board of Directors held in October 2006, Lazard presented several scenarios to the Board for realizing the potential values of the Building Products Group and the Vehicular Products Group as two separate companies. A reverse Morris trust transaction was introduced as an alternative method to achieve a tax free separation of the two Groups.
 
In October 2006, a potential candidate was identified for a reverse Morris trust transaction involving Quanex’s Building Products Group given the company’s size and business composition. From October 2006 through February 2007, Quanex and management of this company exchanged high-level business and financial information and held numerous discussions regarding the potential merits of a reverse Morris trust transaction. At a Quanex Board of Directors meeting held in February 2007, this transaction was presented to the Board and a special committee of the Board was formed to monitor the progress of the potential transaction. During March 2007 and April 2007, the two companies conducted formal due diligence, including numerous site visits, management presentations and the negotiation of merger terms. Quanex and this company, however, were unable to reach agreement on certain key issues and negotiations were ultimately terminated.
 
On May 4, 2007, Quanex’s Board of Directors met with Lazard to review Quanex’s strategic alternatives. At that meeting, it was concluded that the value of the Vehicular Products Group would be enhanced under an alternative growth strategy that might be best achieved through a strategic combination with a larger, more diversified steel company. Given that such a strategy was unlikely to include a combination of the Vehicular Products Group and the Building Products Group, the Board of Directors approved senior management’s formally exploring separation alternatives for the Building Products Group, including the potential sale or spin-off of the division.
 
On May 16, 2007, Quanex publicly announced the strategic review of the Building Products Group. Lazard commenced a sale process for the Building Products Group on May 17, 2007. In total, 72 prospective strategic and financial buyers were contacted, 36 confidentiality agreements were signed and 36 confidential information memoranda were distributed. On July 11, 2007, 11 preliminary indications of interest were received from prospective financial buyers for the Building Products Group
 
On July 14, 2007, Quanex’s Board met with Lazard and approved five parties to be invited to conduct detailed due diligence on the Building Products Group, to include site visits, management presentations and access to an electronic data room. At this meeting the Board of Directors also gave Lazard approval to begin

contacting a targeted list of potential strategic buyers for the Vehicular Products Group to solicit preliminary indications of interest. Lazard contacted 19 parties regarding the Vehicular Products Group, from which eight confidentiality agreements were signed and eight confidential information packages were distributed.
 
In early August 2007, two of the bidders for the Building Products Group elected not to continue with that process, citing deteriorating U.S. credit market conditions. The remaining three bidders attended management presentations in early August, but significantly reduced or retracted their preliminary indications of interest, also citing deteriorating U.S. credit market conditions. During this period the U.S. new home construction market also began to rapidly deteriorate, which significantly reduced management’s confidence that an attractive sale price could be secured for the Building Products Group.
 
On August 28, 2007, the Quanex Board of Directors met with Lazard and discussed the merits of a taxable spin-off of the Building Products Group as a means to facilitate the continuation of the sales process for the Vehicular Products Group.
 
On September 10, 2007, five preliminary indications of interest were received for the Vehicular Products Group ranging from $1,000 million to $1,300 million in enterprise value. All five parties were invited to a second round of due diligence, which included management presentations in Houston, Texas, and access to an electronic data room.
 
On October 12, 2007, the remaining bidders were provided with draft forms of the merger agreement and the spin-off related agreements for their review. Bidders were instructed to submit their second round offers on a per share basis for Quanex, subject to the separation of the Building Products Group through a taxable spin-off, assuming a certain level of net financial debt and other corporate adjustments.
 
On October 24, 2007, three parties submitted non-binding, all cash offers for Quanex. These offers ranged from $19.20 to $32.61 per share, representing $919 million to $1,418 million in enterprise value. In addition, one other offer was submitted under an alternative transaction structure.
 
On October 28, 2007, the Quanex Board met with Lazard to discuss the various offers received and to review the merits of the alternative transaction structure. After review, the Board of Directors instructed Lazard to invite Gerdau and another company to proceed with a third and final round of confirmatory due diligence and final contract negotiations. In addition, the Board of Directors instructed Lazard to determine whether the company that submitted the alternative transaction structure would be prepared to submit an offer on an all cash basis similar to the other offers received. This company declined to proceed on that basis soon thereafter. The Board of Directors also reviewed the merits of a spin-off transaction involving the Building Products Group and decided that Quanex should proceed with a taxable spin-off of the Building Products Group to Quanex stockholders immediately prior to the closing of any transaction involving the Vehicular Products Group.
 
From October 29, 2007 to November 16, 2007, representatives of Quanex and Quanex’s legal advisors continued to negotiate the terms of the merger agreement, the spin-off related agreements and the associated schedules to those agreements with the two remaining bidders. At the same time, both remaining bidders conducted extensive additional due diligence through written questions responded to by Quanex management and telephone conferences attended by representatives of the bidders, their legal counsel, accountants and financial advisers and Quanex’s management, legal counsel, accountants and financial advisers. Both bidders were also provided with the opportunity to visit several of the facilities of the Vehicular Products Group in Lansing, Michigan, Jackson, Michigan, Monroe, Michigan, and Ft. Smith, Arkansas.
 
On the evening of November 16, 2007, Gerdau and the second bidder submitted their final bids to Quanex together with the forms of agreements they would be willing to enter into with Quanex. Gerdau presented a bid of $40.02 per share of outstanding Quanex common stock, or $1,673 million in enterprise value. The second bidder presented a bid of $38.67 per share of outstanding Quanex common stock, or $1,623 million in enterprise value. That night and into the next morning Lazard evaluated the financial impact of the bids while Quanex’s legal counsel evaluated the draft documents provided with the bids.

On November 17, 2007, attorneys for Quanex and Gerdau continued negotiating certain provisions of the agreements. In addition, Lazard representatives held conversations with representatives of the second bidder regarding certain commercial positions that the bidder was proposing in its form of agreements that varied from Quanex’s expectations for the agreements.
 
To facilitate the bidding process, Quanex advised the bidders to make their bids based on the assumption that Quanex, not the Building Products Group, would remain liable for Quanex’s convertible notes and certain expenses of the transaction, including expenses dependent on Quanex’s share price such as the cost of employee stock options, restricted stock and restricted stock units and change-in-control obligations, in a stated amount. Pursuant to the agreements between Quanex and the Building Products Group, if the actual amount, as determined by Quanex’s share price at closing, exceeded the stated amount, the Building Products Group would reimburse Quanex, and if the actual amount was less than the stated amount, Quanex would pay the Building Products Group the difference. Based on the enterprise values reflected in the two final bids, management of Quanex believed that the stated amount underestimated the actual cost of these liabilities and therefore would require the Building Products Group to make a payment to Quanex. To avoid this result, Quanex instructed Gerdau to mathematically adjust its bid to reflect a higher stated amount which would result in it acquiring Quanex with a larger liability. This mathematical adjustment changed the Gerdau bid to $39.20 per share of outstanding Quanex common stock but that bid, with assumed liabilities, continued to reflect an enterprise value of $1,673 million.
 
On the morning of November 18, 2007, at a telephonic special meeting of the Quanex Board of Directors, the Board met to discuss the two bids that had been submitted and the status of negotiations regarding the respective sets of agreements with both bidders. Raymond Jean and other members of senior management of Quanex discussed certain aspects of both bids and the progress that had been made with Gerdau both in the amount of their bid and the status of the transaction agreements. Also, representatives of Lazard presented an overview of the financial aspects of the proposed merger. At the meeting, Lazard delivered its oral opinion to the Quanex Board of Directors followed by delivery of its written opinion, dated November 18, 2007, as described under “— Opinion of Lazard Frères & Co. LLC — Quanex’s Financial Advisor,” to the effect that, as of that date, and based upon and subject to the assumptions made, matters considered and limitations described in the opinion, the consideration to be paid in the merger to holders of shares of Quanex common stock (other than holders of dissenters’ shares and shares of Quanex common stock owned directly by Quanex as treasury stock or by Gerdau or Gerdau Delaware, and in each case not held on behalf of third parties) was fair to such holders from a financial point of view. The Board approved the merger agreement and authorized the Company to enter into the merger agreement with Gerdau and, contingent upon completion of the merger, approved the distribution of Quanex Building Products to Quanex’s stockholders.
 
On November 18, 2007, representatives of the Company and Gerdau executed and delivered the merger agreement.
 
Quanex’s Reasons for the Merger
 
Following a review and discussion of all relevant information regarding the merger, Quanex’s Board of Directors determined that the merger is in the best interests of Quanex and its stockholders. In reaching their conclusion, the members of Quanex’s Board of Directors relied on their personal knowledge of Quanex and the served industries of its operating groups, and the advice of management and Quanex’s legal and financial advisors. The Quanex Board considered numerous factors in favor of the merger agreement, including, among other things, the following:
 
  •  Separating the Building Products Group from the Vehicular Products Group Enhances Stockholder Value.  Separating the groups will better enable each group to reach its full potential. Management did not see the Vehicular Products Group as a consolidator in the steel industry and believes it would be disadvantaged over time in servicing its increasingly global vehicular customers. The ongoing steel consolidation trend, where company size and geographic location can make a competitive difference, is expected to continue. With respect to the Building Products Group, management and the Quanex Board believe it should be managed under an “invest for growth” strategy and that there are rapid growth

opportunities, both organically (particularly as the housing sector rebounds), through new product introduction, and through an acquisition program. Management and the Board also believe the focus on the Building Products Group will permit more corporate vigor and a new level of creativity to be applied to stimulate profitable growth in this sector business.
 
  •  Creating Stockholder Value With Respect to Quanex’s Vehicular Products Group.  The cash to be paid to stockholders, per the terms of the merger agreement, represent a fair value in exchange for the assets and liabilities being assumed by Gerdau. Recent consolidation activity in the market has created enhanced value for a well-positioned business like the Vehicular Products Group. However, it has also created future uncertainty with the potential addition of much larger competitors. As a result, the Board believes that at present there is an unusual opportunity to realize capitalized value for the Quanex stockholders. This view is supported by the fact that the earnings multiple represented by the enterprise value implicit in the total consideration is equal to or higher than multiples paid for similarly situated steel companies in recent years.
 
  •  Opportunity to Raise Equity Market Valuation.  Over the past decade, the current Quanex portfolio of companies has not been rewarded in the equities markets with strong valuation metrics. Equity analysts and institutional investment managers often specialize in specific economic sectors. Because of its unique combination of specialty steel bar mills serving primarily automotive applications, positioned alongside building products businesses serving primarily residential, new home and remodeling markets, Quanex has not neatly fallen into any one investment category, nor has it been classified as a diversified industrial. In addition, Quanex shares have traditionally traded at earnings multiples more in line with steel companies rather than the higher multiples typically associated with building products manufacturers. Management and the Board believe that a separately traded Building Products Group may trade at a higher multiple.
 
The Quanex Board therefore concluded that the merger and the spin-off present an opportunity to maximize the cash value of the Vehicular Products Group under favorable circumstances while giving our stockholders the opportunity to participate in a pure play building products business with greater growth and market pricing potential.
 
Recommendation of the Quanex Board of Directors
 
After careful consideration of the matters discussed above, the Quanex Board of Directors concluded that the proposed merger is advisable and in the best interests of the stockholders of Quanex.
 
FOR THE REASONS SET FORTH ABOVE, THE BOARD OF DIRECTORS OF QUANEX HAS UNANIMOUSLY ADOPTED THE MERGER AGREEMENT AS BEING ADVISABLE AND IN THE BEST INTERESTS OF QUANEX AND ITS STOCKHOLDERS, AND UNANIMOUSLY RECOMMENDS THAT QUANEX’S STOCKHOLDERS VOTE “FOR” APPROVAL AND ADOPTION OF THE MERGER AGREEMENT.
 
Opinion of Lazard Frères & Co. LLC — Quanex’s Financial Advisor
 
Under an engagement letter dated as of October 21, 2006, as amended and restated as of March 16, 2007, Quanex retained Lazard to act as its investment banker in connection with certain potential transactions involving Quanex and its businesses. As part of that engagement, the Board of Directors of Quanex requested that Lazard evaluate the fairness to the holders of shares of Quanex common stock (other than holders of dissenters’ shares and shares of Quanex common stock owned directly by Quanex as treasury stock or by Gerdau or Gerdau Delaware, and in each case not held on behalf of third parties), from a financial point of view, of the consideration to be received by such holders in the merger. On November, 18, 2007, Lazard rendered its opinion to Quanex’s Board of Directors that, as of that date, and subject to certain assumptions, limitations, factors and qualifications set forth therein, the merger consideration of $39.20 per share in cash to be received by each holder of shares of Company common stock (other than holders of dissenters’ shares and shares of Quanex common stock owned directly by Quanex as treasury stock or by Gerdau or Gerdau

Delaware, and in each case not held on behalf of third parties)in the merger was fair to such holders from a financial point of view.
 
The full text of the Lazard opinion, which was approved by Lazard’s opinion committee and which sets forth, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by Lazard in connection with the opinion, is attached as Annex B to this proxy statement and is incorporated into this proxy statement by reference. You are urged to read Lazard’s opinion carefully in its entirety.
 
In connection with rendering its opinion, Lazard:
 
(i) reviewed the financial terms and conditions of the draft, dated November 18, 2007, of the merger agreement;
 
(ii) analyzed certain publicly available historical business and financial information relating to Quanex;
 
(iii) reviewed various financial forecasts and other data provided to Lazard by the management of Quanex relating to the business and prospects of Quanex after giving effect to the disposition of Quanex’s Building Products Group;
 
(iv) held discussions with members of the senior management of Quanex with respect to the business and prospects of Quanex after giving effect to the disposition of Quanex’s Building Products Group;
 
(v) reviewed public information with respect to certain other companies in lines of business Lazard believes to be generally comparable to the business of Quanex after giving effect to the disposition of Quanex’s Building Products Group;
 
(vi) reviewed the financial terms of certain business combinations involving companies in lines of business Lazard believes to be generally comparable to the business of Quanex after giving effect to the disposition of Quanex’s Building Products Group;
 
(vii) reviewed the historical stock prices and trading volumes of Quanex’s common stock; and
 
(viii) conducted such other financial studies, analyses and investigations as Lazard deemed appropriate.
 
Lazard relied upon the accuracy and completeness of the foregoing information and did not assume any responsibility for any independent verification of (and did not independently verify) such information or any independent valuation or appraisal of any of the assets or liabilities of Quanex or concerning the solvency or fair value of Quanex. With respect to financial forecasts, Lazard assumed that they were reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of Quanex as to the future financial performance of Quanex. Lazard assumed no responsibility for and expressed no view as to such forecasts or the assumptions on which they were based.
 
In rendering its opinion, Lazard assumed that the merger agreement would be identical in all material respects to the draft merger agreement reviewed by Lazard and that the merger would be consummated on the terms described in the merger agreement without any waiver or modification of any material terms or conditions. Lazard further assumed that obtaining the necessary regulatory approvals and contractual consents for the merger and the disposition of the Building Products Group would not have an adverse effect on Quanex or the merger. In addition, Lazard assumed the representations and warranties contained in the merger agreement and all agreements related thereto were true and correct in all material respects. Lazard did not express any opinion as to any tax or other consequences that might result from the merger or the disposition of the Building Products Group, nor did the Lazard opinion address any legal, tax, regulatory or accounting matters, as to which Lazard understood that Quanex obtained such advice it deemed necessary from qualified professionals. In addition, Lazard did not express any opinion about the fairness of the amount or nature of, or any other aspect of, the compensation to any of Quanex’s officers, directors or employees, or any class of such persons, relative to the merger consideration to be paid to Quanex’s public stockholders or otherwise.

Table of Contents

In rendering the Lazard opinion, Lazard further assumed that the stockholders of Quanex prior to the consummation of the merger (and not the owners of Quanex after giving effect to the merger) will either own or be entitled to receive the proceeds of the disposition of Quanex’s Building Products Group. Lazard expressed no opinion as to the value of Quanex’s Building Products Group or as to the fairness or any other aspect of the disposition of Quanex’s Building Products Group.
 
Lazard’s opinion was for the benefit of the Board of Directors in connection with its consideration of the merger and only addressed the fairness to the holders of shares of common stock (other than holders of dissenters’ shares and shares of Quanex common stock owned directly by Quanex as treasury stock or by Gerdau or Gerdau Delaware, and in each case not held on behalf of third parties) of the merger consideration to be paid to such holders in the merger from a financial point of view as of the date of the Lazard opinion. Lazard’s written opinion did not address the relative merits of the merger as compared to other business strategies or transactions that might be available to Quanex or the underlying decision by Quanex to engage in the merger, and was not intended to and does not constitute a recommendation to Quanex’s stockholders as to how such stockholders should vote with respect to the merger or any matter relating thereto. Lazard’s opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to Lazard as of, the date of the Lazard opinion. Lazard assumed no responsibility for updating or revising the Lazard opinion based on circumstances or events occurring after the date of the Lazard opinion. Lazard expressed no opinion as to the price at which shares of Quanex’s common stock may trade at any time subsequent to the announcement of the merger. The following is only a summary of the Lazard opinion. You are urged to read the entire Lazard opinion.
 
The following is a summary of the material financial analyses that Lazard performed in connection with rendering its opinion. The summary of Lazard’s analyses described below is not a complete description of the analyses underlying Lazard’s opinion. The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analyses and the application of those methods to the particular circumstances, and, therefore, is not readily susceptible to summary description. In arriving at its opinion, Lazard considered the results of all the analyses and did not attribute any particular weight to any factor or analysis considered by it; rather, Lazard made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of the analyses.
 
For purposes of its analyses, Lazard considered industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Quanex. No company, transaction or business used in Lazard’s analyses as a comparison is identical to Quanex, either before or after giving effect to the disposition of the Building Products Group, or the merger, and an evaluation of the results of those analyses is not entirely mathematical. Rather, the analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, business segments or transactions analyzed. The estimates contained in Lazard’s analyses and the ranges of valuations resulting from any particular analysis are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by the analyses. In addition, analyses relating to the value of businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold. Accordingly, the estimates used in, and the results derived from, Lazard’s analyses are inherently subject to substantial uncertainty.
 
The financial analyses summarized below include information presented in tabular format. In order to fully understand Lazard’s financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Lazard’s financial analyses.

Financial Analyses
 
Discounted Cash Flow Analysis.  Based on the base case and downside case projections provided to Lazard by Quanex, Lazard performed a discounted cash flow analysis of Quanex to calculate the estimated present value of the standalone, unlevered, after-tax free cash flow that Quanex, after giving effect to the disposition of the Building Products Group, could generate during the fiscal years ended October 31, 2008 through October 31, 2011. Lazard calculated estimated terminal values for Quanex, after giving effect to the disposition of the Building Products Group, by applying a range of multiples of 5.0x to 6.0x to Quanex’s fiscal year ended October 31, 2011 base case and downside case estimated earnings before interest, taxes, depreciation and amortization, referred to as EBITDA. The standalone, unlevered, after-tax free cash flows and terminal values were discounted to present value using discount rates ranging from 11.25% to 12.75%, which were based on the weighted average cost of capital of a selected group of global steel producers. Based on this analysis, Lazard calculated an implied enterprise value range for Quanex of approximately $915 million to $1,080 million in the base case and $720 million to $840 million in the downside case. A company’s enterprise value is equal to its short and long term debt plus the market value of its common equity and the value of any preferred stock (at liquidation value), minus its cash and cash equivalents.
 
Comparable Company Analysis.  Lazard reviewed and analyzed selected public companies in the steel industry that it viewed as reasonably comparable to Quanex, after giving effect to the disposition of the Building Products Group. In performing these analyses, Lazard reviewed and analyzed publicly available financial information relating to the selected companies and compared that information to the corresponding information for Quanex, after giving effect to the disposition of the Building Products Group, based on the forecasts of management of Quanex. Specifically, Lazard compared Quanex, after giving effect to the disposition of the Building Products Group, to the following five public companies in the steel industry:
 
  •  The Timken Company;
 
  •  Steel Dynamics, Inc.;
 
  •  Nucor Corporation;
 
  •  Commercial Metals Company; and
 
  •  Gerdau Ameristeel Corporation.
 
Based on equity analysts’ estimates and other public information, Lazard reviewed, among other things, the enterprise value of each selected comparable company as a multiple of such company’s estimated EBITDA, for calendar year 2008, and each comparable company’s closing stock price on November 16, 2007, as a multiple of such comparable company’s estimated earnings per share, referred to as EPS, for calendar year 2008.
 
Lazard calculated the following multiples for the above comparable companies:
 
                 
          November 16, 2007
 
    Enterprise Value/EBITDA
    Closing Stock Price/EPS
 
    CY 2008E     CY 2008E  
 
Low
    4.8 x     7.3 x
Mean
    5.3 x     9.2 x
High
    5.8 x     10.6 x
 
Based on the foregoing, Lazard applied EBITDA multiples of 5.0x to 6.0x to Quanex’s calendar year 2008 estimated EBITDA, after giving effect to the disposition of the Building Products Group, provided by Quanex’s management, and determined an implied enterprise value range of $970 million to $1,165 million.
 
Comparable Transactions Analysis.  Lazard reviewed and analyzed selected precedent merger and acquisition transactions involving companies in the steel industry. In performing these analyses, Lazard analyzed certain financial information and transaction multiples relating to companies in the selected transactions and compared such information to the corresponding information for Quanex, after giving effect to the disposition of the Building Products Group. Specifically, Lazard reviewed 14 merger and acquisition

transactions since November 2005 involving companies in the steel industry for which sufficient public information was available. Lazard reviewed, among other things, the transaction value of each acquired company implied by the transaction as a multiple of the acquired company’s EBITDA for the last twelve months, or LTM, prior to the public announcement of the transaction.
 
The precedent transactions were (listed by acquirer followed by the acquired company and the date the transaction was publicly announced):

Based on the foregoing, Lazard applied LTM EBITDA multiples of 7.0x to 8.9x to Quanex’s LTM EBITDA as provided by Quanex’s management, and determined an implied enterprise value range of $1,130 million to $1,430 million.
 
Miscellaneous
 
In connection with Lazard’s services as investment banker to Quanex, Quanex agreed to pay Lazard a fee of 0.7% of the aggregate transaction consideration, or $11.7 million, a substantial portion of which is payable upon consummation of the merger. Lazard will also be entitled to receive a separate fee in connection with the disposition of Quanex’s Building Products Group. Lazard and Quanex have agreed that if the disposition of the buildings products business is accomplished through a spin-off, split-off or similar transaction, and Lazard serves as the resulting entity’s investment banker in connection with a subsequent sale, merger, consolidation or business combination transaction, within 18 months following the disposition, a portion of the fee to be paid to Lazard in connection with Quanex’s disposition of the Building Products Group will be credited against the fee payable to Lazard by the resulting entity in such second stage transaction. The Company has also agreed to reimburse Lazard for all expenses incurred in connection with the engagement and to indemnify Lazard and certain related parties against certain liabilities under certain circumstances that may arise out of the rendering of its advice, including certain liabilities under U.S. federal securities laws.

Lazard, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements, leveraged buyouts, and valuations for estate, corporate and other purposes. In addition, in the ordinary course of their respective businesses, affiliates of Lazard and LFCM Holdings LLC (an entity owned in large part by managing directors of Lazard) may actively trade securities of Quanex and/or the securities of Gerdau for their own accounts and for the accounts of their customers and, accordingly, may at any time hold for a long or short position in such securities.
 
Lazard is an internationally recognized investment banking firm providing a full range of financial advisory and securities services. Lazard was selected to act as investment banker to Quanex because of its qualifications, expertise and reputation in investment banking and mergers and acquisitions, as well as its familiarity with the businesses of Quanex.
 
The opinion of Lazard was one of many factors taken into consideration by Quanex’s Board of Directors. Consequently, the analyses described above should not be viewed as determinative of the opinion of Quanex’s Board of Directors with respect to the merger consideration or of whether Quanex’s Board of Directors would have been willing to recommend a merger transaction with different merger consideration. Additionally, Lazard’s opinion is not intended to confer any rights or remedies upon any employee or creditor of Quanex.
 
Regulatory Matters
 
The merger is subject to review by the DOJ and the FTC under the Hart-Scott-Rodino Act. The Hart-Scott-Rodino Act, and the rules promulgated under it by the FTC, prevent transactions, such as the merger, from being completed until required information and materials are furnished to the DOJ and the FTC and certain waiting periods are terminated or expire. The initial waiting period is 30 days after both parties have filed the applicable notifications, but this period may be extended if the reviewing agency issues a formal request for additional information and documentary material, referred to as a second request. On November 30, 2007, the parties submitted the notification filings with the DOJ and the FTC. The waiting period under the Hart-Scott-Rodino Act will expire on December 31, 2007, unless each party receives early termination of the waiting period before that time.
 
The DOJ, the FTC and others may also challenge the merger on antitrust grounds either before or after expiration or termination of the waiting period. Accordingly, at any time before or after the completion of the merger, the DOJ, the FTC or another regulatory agency could take action under the antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the merger or permitting completion subject to regulatory concessions or conditions. We cannot assure you that a challenge to the merger will not be made or that, if a challenge is made, it will not prevail.
 
A party or parties to a transaction may, but are not required to, submit to the Committee on Foreign Investment in the United States, which we refer to as CFIUS, in accordance with the regulations implementing Section 721 of the Defense Production Act of 1950, as amended, a voluntary notice of the transaction. Section 721 empowers the President of the United States to prohibit or suspend an acquisition of, or investment in, a U.S. company by a “foreign person” if the President of the United States, after investigation, finds credible evidence that the foreign person might take action that threatens to impair the national security of the United States and that other provisions of existing law, other than the International Emergency Economic Powers Act, do not provide adequate and appropriate authority to protect the national security. CFIUS has the authority to receive notices of proposed transactions, determine when an investigation is warranted, conduct investigations and submit recommendations to the President of the United States to suspend or prohibit the completion of transactions or to require divestitures of completed transactions.
 
On             , 200 , the parties submitted a notice of the transaction to CFIUS. CFIUS has 30 calendar days from the date of submission to decide whether to initiate an investigation. If CFIUS declines to investigate, it sends a letter advising the parties that CFIUS has determined not to conduct an investigation and that CFIUS has concluded its review of the transaction, and the review process is complete. If CFIUS decides to investigate, it has 45 calendar days in which to prepare a recommendation to the President of the


26


Table of Contents

United States, who must then decide within 15 calendar days whether to block the transaction or, in the case of a completed transaction, seek a divestiture.
 
Although Quanex and Gerdau do not believe an investigation of, or recommendation to block, the merger by CFIUS is warranted under the standards of Section 721, CFIUS and the President of the United States have considerable discretion to conduct investigations and block transactions under Section 721.
 
Other than as we describe in this document, the approval of any other U.S. federal or state agency or any foreign agency is not a condition to completion of the transaction.
 
Appraisal Rights
 
Under the DGCL, any Quanex stockholder who does not wish to accept the merger consideration has the right to dissent from the merger and to seek an appraisal of, and to be paid the fair value (exclusive of any element of value arising from the accomplishment or expectation of the merger) for his or her shares of Quanex common stock, so long as the stockholder complies with the provisions of Section 262 of the DGCL.
 
Holders of record of Quanex common stock who do not vote in favor of the merger agreement and who otherwise comply with the applicable statutory procedures summarized in this proxy statement will be entitled to appraisal rights under Section 262 of the DGCL. A person having a beneficial interest in shares of Quanex common stock held of record in the name of another person, such as a broker or nominee, must act promptly to cause the record holder to follow the steps summarized below properly and in a timely manner to perfect appraisal rights.
 
THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE LAW PERTAINING TO APPRAISAL RIGHTS UNDER THE DGCL AND IS QUALIFIED IN ITS ENTIRETY BY THE FULL TEXT OF SECTION 262 OF THE DGCL, WHICH IS REPRINTED IN ITS ENTIRETY AS ANNEX C. ALL REFERENCES IN SECTION 262 OF THE DGCL AND IN THIS SUMMARY TO A “STOCKHOLDER” OR “HOLDER” ARE TO THE RECORD HOLDER OF THE SHARES OF COMMON STOCK AS TO WHICH APPRAISAL RIGHTS ARE ASSERTED.
 
Under Section 262 of the DGCL, holders of shares of Quanex common stock who follow the procedures set forth in Section 262 of the DGCL will be entitled to have their shares of Quanex common stock appraised by the Delaware Chancery Court and to receive payment in cash of the “fair value” of those shares of Quanex common stock, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with a fair rate of interest, if any, as determined by that court.
 
Under Section 262 of the DGCL, when a proposed merger is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, must notify each of its stockholders who was a stockholder on the record date for the meeting with respect to shares for which appraisal rights are available, that appraisal rights are so available, and must include in that required notice a copy of Section 262 of the DGCL.
 
This proxy statement constitutes the required notice to the holders of those shares of Quanex common stock and the applicable statutory provisions of the DGCL are attached to this proxy statement as Annex C. Any Quanex stockholder who wishes to exercise his or her appraisal rights or who wishes to preserve his or her right to do so should review the following discussion and Annex C carefully because failure to timely and properly comply with the procedures specified in Annex C will result in the loss of appraisal rights under the DGCL.
 
A holder of shares of Quanex common stock wishing to exercise his or her appraisal rights (a) must not vote in favor of the merger agreement and (b) must deliver to Quanex prior to the vote on the merger agreement at the Quanex special meeting, a written demand for appraisal of his or her shares of Quanex common stock. This written demand for appraisal must be in addition to and separate from any proxy or vote abstaining from or against the merger. This demand must reasonably inform Quanex of the identity of the stockholder and of the stockholder’s intent thereby to demand appraisal of his or her shares. A holder of shares of Quanex common stock wishing to exercise his or her appraisal rights must be the record holder of such


27


Table of Contents

shares on the date the written demand for appraisal is made and must continue to hold such shares until the consummation of the merger. Accordingly, a holder of shares of Quanex common stock who is the record holder of shares of Quanex common stock on the date the written demand for appraisal is made, but who thereafter transfers such shares prior to consummation of the merger, will lose any right to appraisal in respect of such shares.
 
Only a holder of record of shares of Quanex common stock is entitled to assert appraisal rights for the Quanex shares registered in that holder’s name. A demand for appraisal should be executed by or on behalf of the holder of record, fully and correctly, as the holder’s name appears on the holder’s stock certificates. If the shares of Quanex common stock are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, execution of the demand should be made in that capacity, and if the shares of Quanex common stock are owned of record by more than one owner 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 holder of record. The agent, however, must identify the record owner or owners and expressly disclose the fact that, in executing the demand, the agent is agent for the owner or owners. A record holder such as a broker who holds shares of Quanex common stock as nominee for several beneficial owners may exercise appraisal rights with respect to shares of Quanex common stock held for one or more beneficial owners while not exercising appraisal rights with respect to shares of Quanex common stock held for other beneficial owners. In this case, the written demand should set forth the number of shares of Quanex common stock as to which appraisal is sought. When no number of shares of Quanex common stock is expressly mentioned, the demand will be presumed to cover all shares of Quanex common stock in brokerage accounts or other nominee forms, and those who wish to exercise appraisal rights under Section 262 of the DGCL are urged to consult with their brokers to determine the appropriate procedures for the making of a demand for appraisal by such a nominee.
 
ALL WRITTEN DEMANDS FOR APPRAISAL SHOULD BE SENT OR DELIVERED TO QUANEX CORPORATION, 1900 WEST LOOP SOUTH, SUITE 1500, HOUSTON, TEXAS 77027, ATTENTION: SECRETARY.
 
Within ten days after the effective time of the merger, Gerdau will notify each stockholder who has properly asserted appraisal rights under Section 262 of the DGCL and has not voted in favor of the merger agreement.
 
Within 120 days after the effective time of the merger, but not thereafter, Gerdau or any stockholder who has complied with the statutory requirements summarized above may file a petition in the Delaware Chancery Court demanding a determination of the fair value of the shares of Quanex common stock held by those stockholders. None of Gerdau, Gerdau Delaware or Quanex is under any obligation to and none of them has any present intention to file a petition with respect to the appraisal of the fair value of the Quanex shares. Accordingly, it is the obligation of stockholders wishing to assert appraisal rights to initiate all necessary action to perfect their appraisal rights within the time prescribed in Section 262 of the DGCL.
 
Within 120 days after the effective time of the merger, any Quanex stockholder who has complied with the requirements for exercise of appraisal rights will be entitled, upon written request, to receive from Gerdau a statement setting forth the aggregate number of shares of Quanex common stock not voted in favor of adoption of the merger agreement and with respect to which demands for appraisal have been received and the aggregate number of holders of those shares of Quanex common stock. That statement must be mailed to those stockholders within ten days after a written request therefor has been received by Gerdau.
 
If a petition for an appraisal is filed timely, at a hearing on the petition, the Delaware Chancery Court will determine the stockholders entitled to appraisal rights. After determining those stockholders, the Delaware Chancery Court will appraise the “fair value” of their Quanex shares, exclusive of 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. Stockholders considering seeking appraisal should be aware that the fair value of their Quanex shares as determined under Section 262 of the DGCL 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 Quanex common stock and that investment banking

opinions as to fairness from a financial point of view are not necessarily opinions as to fair value under Section 262 of the DGCL. The Delaware Supreme Court has stated that “proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court” should be considered in the appraisal proceedings.
 
The Delaware Chancery Court will determine the amount of interest, if any, to be paid upon the amounts to be received by stockholders whose shares of Quanex common stock have been appraised. The costs of the appraisal proceeding may be determined by the Delaware Chancery Court and taxed upon the parties as the Delaware Chancery Court deems equitable. The Delaware Chancery Court may also order that all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys’ fees and the fees and expenses of experts used in the appraisal proceeding, be charged pro rata against the value of all of the shares of Quanex common stock entitled to appraisal.
 
Any holder of shares of Quanex common stock who has duly demanded an appraisal in compliance with Section 262 of the DGCL will not, after the effective time of the merger, be entitled to vote the shares of Quanex common stock subject to that demand for any purpose or be entitled to the payment of dividends or other distributions on those shares of Quanex common stock (except dividends or other distributions payable to holders of record of shares of Quanex common stock as of a record date prior to the effective time of the merger).
 
If any stockholder who properly demands appraisal of his or her shares of Quanex common stock under Section 262 of the DGCL fails to perfect, or effectively withdraws or loses, his or her right to appraisal, as provided in Section 262 of the DGCL, the shares of Quanex common stock of that stockholder will be converted into the right to receive the merger consideration receivable with respect to these shares of Quanex common stock in accordance with the merger agreement. A stockholder will fail to perfect, or effectively lose or withdraw, his or her right to appraisal if, among other things, no petition for appraisal is filed within 120 days after the consummation of the merger, or if the stockholder delivers to Quanex or Gerdau, as the case may be, a written withdrawal of his or her demand for appraisal. Any attempt to withdraw an appraisal demand in this matter more than 60 days after the consummation of the merger will require the written approval of the surviving company.
 
Failure to follow the steps required by Section 262 of the DGCL for perfecting appraisal rights may result in the loss of these rights, in which event a Quanex stockholder will be entitled to receive the merger consideration receivable with respect to his or her shares of Quanex common stock in accordance with the merger agreement.
 
Delisting and Deregistration of Quanex Common Stock
 
If the merger is completed, the shares of Quanex common stock will be delisted from the NYSE and will be deregistered under the Securities Exchange Act of 1934.
 
Accounting Treatment
 
We expect that the merger will be accounted for as a business combination using the purchase method of accounting for financial accounting purposes, whereby the purchase price would be allocated to our assets and liabilities based on their relative fair values following Financial Accounting Standards Board Statement of Financial Accounting Standards No. 141, Business Combinations.
 
Material U.S. Federal Income Tax Consequences
 
The following discussion summarizes the material U.S. federal income tax consequences of the spin off and the merger that may be relevant to Quanex stockholders who hold shares of Quanex common stock as a capital asset for U.S. federal income tax purposes (generally, assets held for investment) and who or that are for U.S. federal income tax purposes:
 
  •  an individual who is a citizen or resident of the United States (including certain former citizens and former long-term residents);


29


Table of Contents

 
  •  a corporation, or other entity taxable as a corporation for U.S. federal tax purposes, created or organized in or under the laws of the United States or any state thereof or the District of Columbia;
 
  •  an estate the income of which is subject to U.S. federal income taxation regardless of its source; or
 
  •  a trust (i) that is subject to the primary supervision of a court within the United States and the control of one or more United States persons as defined in section 7701(a)(30) of the Code or (ii) that has a valid election in effect under applicable Treasury regulations to be treated as a United States person.
 
This discussion is addressed only to those Quanex stockholders who exchange shares of Quanex common stock for cash in the merger.
 
This discussion is based on the Internal Revenue Code of 1986, as amended, or the Code, Treasury regulations promulgated thereunder, court decisions, published rulings of the Internal Revenue Service, or the IRS, and other applicable authorities, all as in effect on the date of this proxy statement and all of which are subject to change or differing interpretations, possibly with retroactive effect.
 
This discussion does not address all of the U.S. federal income tax consequences that may be relevant to Quanex stockholders in light of their particular circumstances or to Quanex stockholders who may be subject to special treatment under U.S. federal income tax laws, such as tax exempt organizations, foreign persons or entities, S corporations or other pass-through entities, financial institutions, insurance companies, broker-dealers, persons who hold Quanex shares as part of a hedge, straddle, wash sale, synthetic security, conversion transaction, or other integrated investment comprised of shares of Quanex common stock and one or more investments, persons whose “functional currency” (as defined in the Code) is not the U.S. dollar, persons who exercise appraisal rights, and persons who acquired shares of Quanex common stock in compensatory transactions. Further, this discussion does not address any aspect of state, local, or foreign taxation.
 
We have not sought nor obtained an opinion of counsel or any advance tax ruling from the IRS regarding the U.S. federal income tax consequences described below. If the IRS contests a conclusion set forth herein, no assurance can be given that a Quanex stockholder would ultimately prevail in a final determination by a court. Quanex stockholders are urged to consult their own tax advisors as to the U.S. federal income tax consequences of the spin-off and the merger, as well as the effects of state, local, and foreign tax laws.
 
If a partnership (or other entity classified as a partnership for U.S. federal tax purposes) is a beneficial owner of shares of Quanex common stock, the tax treatment of a partner in that partnership will generally depend on the status of the partner and the activities of the partnership. Quanex stockholders that are partnerships and partners in these partnerships are urged to consult their tax advisors regarding the U.S. federal income tax consequences of the spin-off and the merger to them.
 
THIS SUMMARY IS NOT A SUBSTITUTE FOR AN INDIVIDUAL ANALYSIS OF THE TAX CONSEQUENCES OF THE SPIN OFF AND THE MERGER TO YOU. WE URGE YOU TO CONSULT YOUR TAX ADVISOR REGARDING THE PARTICULAR FEDERAL, STATE, LOCAL, AND FOREIGN TAX CONSEQUENCES OF THE SPIN OFF AND THE MERGER IN LIGHT OF YOUR OWN SITUATION.
 
Tax Consequences of the Spin-Off and the Merger to Quanex Stockholders
 
Quanex believes, and the parties to the merger agreement intend, that for U.S. federal income tax purposes the spin-off and the merger will constitute a single integrated transaction with respect to the Quanex stockholders in which the spin-off will be treated as a redemption of shares of Quanex common stock in connection with the complete termination of Quanex stockholders interests in Quanex. Quanex will treat and report the spin-off and the merger in a manner consistent with such characterization. Under such characterization, Quanex stockholders should generally recognize capital gain or loss for U.S. federal income tax purposes in an amount equal to the difference between (i) the sum of the amount of cash received in the merger and the fair market value, determined when the spin-off occurs, of the property received in the spin-off, and (ii) such Quanex stockholder’s adjusted tax basis in his shares of Quanex common stock immediately prior to the spin-off.


30


Table of Contents

The deduction of any recognized loss may be delayed or otherwise adversely affected by certain loss limitation rules. Any such gain or loss will generally be long-term capital gain or loss if the Quanex stockholder’s holding period in the shares of Quanex common stock immediately prior to the spin-off is more than one year. The amount and character of gain or loss must be calculated separately for each identifiable block of shares of Quanex common stock surrendered. Each Quanex stockholder is urged to consult his tax advisor regarding the manner in which gain or loss should be calculated as a result of the spin-off and the merger.
 
Although Quanex believes the foregoing treatment correctly characterizes the transaction for U.S. federal income tax purposes, there is no direct authority on point, and the IRS could challenge the treatment of the spin-off and the merger as a single integrated transaction for U.S. federal income tax purposes. Such a challenge, if successful, could result in Quanex stockholders being treated as receiving a “dividend” distribution in the spin-off in respect of their shares of Quanex common stock and as selling, in a separate transaction, their shares of Quanex common stock in the merger immediately after the spin-off. Under such characterization, the fair market value of the property treated as received by a Quanex stockholder in the spin-off would generally (i) be treated as a dividend to the Quanex stockholder to the extent of our current or accumulated earnings and profits, (ii) to the extent such amount exceeded our earnings and profits, it would be applied to reduce, but not below zero, each Quanex stockholder’s adjusted basis in such Quanex stockholder’s shares of Quanex common stock, and (iii) to the extent such amount exceeded the sum of the amounts described in (i) and (ii), would be taxable as capital gain to each Quanex stockholder. It is not clear whether corporations would be entitled to a “dividends received deduction” or whether individuals would be entitled to preferential rates with respect “qualified dividend income.” In the merger, each Quanex stockholder would generally recognize gain or loss in an amount equal to the difference between the amount of cash received and such Quanex stockholder’s adjusted basis in the shares of Quanex common stock immediately prior to the merger, taking into account the effect of the spin-off on such adjusted basis as described above. Quanex stockholders should consult their tax advisors with respect to the tax consequences of the spin-off and the merger.
 
Information Reporting and Backup Withholding
 
Under U.S. federal income tax laws, the exchange agent will generally be required to report to a Quanex stockholder and to the IRS any reportable payments made to such Quanex stockholder in the spin-off and the merger. Additionally, a Quanex stockholder may be subject to a backup withholding tax, unless the Quanex stockholder provides the exchange agent with his correct taxpayer identification number, which in the case of an individual is his social security number, or, in the alternative, establishes a basis for exemption from backup withholding. If the correct taxpayer identification number or an adequate basis for exemption is not provided, a Quanex stockholder will be subject to backup withholding (which will be satisfied out of any cash paid to such Quanex stockholder in the merger) on any reportable payment. To prevent backup withholding, each Quanex stockholder must complete the IRS Form W-9 or a substitute Form W-9 which will be provided by the exchange agent with the transmittal letter. Any amounts withheld under the backup withholding rules from a payment to a Quanex stockholder will be allowed as a credit against his U.S. federal income tax liability and may entitle him to a refund, if the required information is furnished to the IRS.
 
The foregoing discussion is for general information only and is not intended to be legal or tax advice to any particular Quanex stockholder. Tax matters regarding the spin-off and the merger are very complicated, and the tax consequences of the spin-off and merger to any particular Quanex stockholder will depend on that stockholder’s particular situation. Quanex stockholders should consult their own tax advisor to determine the specific tax consequences of the spin-off and the merger, including tax return reporting requirements, the applicability of U.S. federal, state, local, and foreign tax laws, and the effect of any proposed change in the tax laws to them.

INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
In considering the recommendation of the Quanex Board of Directors with respect to the merger, Quanex stockholders should be aware that some directors and executive officers of Quanex have interests in the merger that are different from, or in addition to, the interests of Quanex stockholders generally. The Quanex Board of Directors was aware of those interests and took them into account in approving and adopting the merger agreement and recommending that Quanex stockholders vote to approve and adopt the merger agreement. Those interests are summarized below.
 
Quanex’s Stock Options, Restricted Stock Units and Restricted Stock
 
As of December 10, 2007, an aggregate of 850,112 shares of our common stock subject to stock options, 6,019 restricted stock units and 43,417 shares of restricted stock were held by our directors and executive officers under our equity incentive plans.
 
At the effective time of the merger, Quanex stock options will become vested and exercisable and will be cancelled. The holder of such Quanex stock options will be entitled to receive an amount in cash equal to: (x) the total number of shares of Quanex common stock subject to the stock option times (y) the excess of (i) the sum of (A) $39.20 and (B) the closing sales price of a share of Quanex Building Products common stock on the NYSE on the distribution date for the spin-off of Quanex’s Building Products Group over (ii) the exercise price per share under the stock option, less any applicable withholding.
 
Each restricted stock unit that has been issued but has not vested prior to the effective time of the merger will become fully vested at the effective time of the merger and will be converted into the right to receive an amount per restricted stock unit equal to the sum of (y) $39.20 and (z) the closing sales price of a share of Quanex Building Products common stock on the NYSE on the distribution date for the spin-off of Quanex’s Building Products Group.
 
Pursuant to the terms of the spin-off of Quanex’s Building Products Group, all shares of Quanex restricted stock that have been issued but have not vested immediately prior to the record date for the spin-off will become fully vested at such time, and on the distribution date for the spin-off, the owners of such shares will be entitled to participate in the spin-off, and, at the effective time of the merger, the owners of such shares will be entitled to receive the merger consideration in exchange for their shares.
 
The following table summarizes the stock options, restricted stock units, and restricted stock held by each of our directors and executive officers as of December 10, 2007, and the consideration (calculated prior to any reduction for any required withholding taxes) that each of them will receive pursuant to the merger agreement in connection with the conversion of restricted stock units and restricted stock and the cancellation of options in the merger (assuming that a share of Quanex Building Products common stock on the distribution date for the spin-off equals $13.29):

Indemnification of Officers and Directors
 
Following the effective time of the merger, Gerdau and the surviving company will indemnify and hold harmless, and provide advancements of expenses to, each present and former officer or director of Quanex or any of its subsidiaries. This indemnification will include indemnification against all losses, expenses (including reasonable attorneys’ fees and expenses), claims, damages and liabilities arising out of actions or omissions occurring at or prior to the effective time of the merger (whether asserted or claimed prior to, at or after the effective time of the merger) that are based on the fact that the person is or was a director or officer of Quanex or any of its subsidiaries.
 
For six years after the effective time of the merger, Gerdau will also maintain in effect directors’ and officers’ liability insurance covering acts or omissions occurring prior to the effective time of the merger with respect to those directors and officers of Quanex who were covered by, and on terms and in amounts no less favorable than those of, Quanex’s directors’ and officers’ liability insurance at the time the merger agreement was executed. In no event will the surviving company be required to pay aggregate annual premiums for insurance in excess of three times the most recent aggregate annual premium paid by Quanex for such purpose (which most recent aggregate annual premium was $561,500 in the aggregate) provided, further, that if the annual premiums of such insurance coverage exceed such amount, the surviving company will be obligated to obtain a policy with the best coverage available, in the reasonable judgment of the Board of Directors of the surviving company, for a cost up to but not exceeding 300% of the most recent aggregate annual premium paid by Quanex. In addition, for six years after the effective time of the merger, Gerdau will cause the surviving company to maintain in effect fiduciary liability insurance policies for employees who serve or have served as fiduciaries under or with respect to any employee benefit plans described in the disclosure schedules with coverages and in amounts no less favorable than those of the policies of Quanex in effect on the date of the merger agreement.
 
Quanex’s Frozen Non-Employee Director Retirement Plan
 
The Quanex Non-Employee Director Retirement Plan, which was previously frozen, will be terminated as of the effective time of the merger, and each former or present director who has accrued benefits under the plan will be paid a lump sum cash payment of the present value of the director’s accrued benefits, discounted using the interest rate for 30-year Treasury securities for the month of August 2007 (which rate is used for lump sum determinations under the Quanex Employee’s Pension Plan) or the interest rate for 30-year Treasury securities for the last month preceding the month in which the effective time occurs, which ever provides the higher lump sum amount.
 
Change-in-Control Agreements with Executive Officers
 
In the past, the Company entered into change in control agreements (the “change-in-control agreements”) with Raymond A. Jean, Thomas M. Walker, Kevin P. Delaney, John J. Mannion, Paul A. Hammonds, Mark A. Marcucci and Brent L. Korb (each, an “executive”). On November 18, 2007, the Board authorized and approved waiver and release agreements (the “waivers”) with each of the executives with the exception of Mr. Marcucci. The waivers provide that the change-in-control agreements with these executives will be deemed to have terminated immediately prior to the closing date of the merger, and the executive will release Quanex from all claims he may have had with respect to his change-in-control agreement. The waivers are conditioned upon the consummation of the merger and the spin-off as well as the executive being offered employment by Quanex Building Products at a level of base pay and cash incentive bonus opportunities at or higher than the level the executive has at present with Quanex along with other conditions.
 
The waivers provide that (i) any outstanding unvested stock options that the executive holds will immediately vest and be exercisable; (ii) all restrictions on any restricted stock held by the executive will immediately lapse and the restricted stock will become free of restrictions and be transferable; (iii) the executive will be fully vested in his entire account balance under Quanex’s Deferred Compensation Plan or any portion of such plan that is spun-off to Quanex Building Products as a result of the spin-off; and (iv) the

executive’s accrued benefit under Quanex’s Supplemental Benefit Plan will be spun-off to Quanex Building Products as a result of the spin-off.
 
In conjunction with the waivers, Quanex will also pay each executive the following:
 
  •  If a performance unit award was granted to the executive in 2005 pursuant to Quanex’s 2003 Long-Term Incentive Plan, an amount equal to the number of units granted under the award times the target value of the award times 3/3; plus
 
  •  If a performance unit award was granted to the executive in 2006 under Quanex’s 2006 Omnibus Incentive Plan, an amount equal to the number of units granted under the award times the target value of the award times 2/3; plus
 
  •  An amount equal to the executive’s bonus under the fiscal year 2008 bonus plan as determined by the Quanex Board of Directors times a fraction, the numerator of which is the number of days in the current fiscal year through the closing date and the denominator of which is 365.
 
The waivers provide that the executive is entitled to a gross-up payment for any excise taxes that are imposed upon him under Section 4999 of the Code as a result of these or any payments made by Quanex being deemed to be “excess parachute payments” under Section 280G of the Code.
 
We currently value these benefits (excluding the acceleration of equity awards) for Mr. Jean at approximately $1,526,667, for Mr. Walker at approximately $329,375, for Mr. Delaney at approximately $336,458, for Mr. Mannion at approximately $103,333, for Mr. Hammonds at approximately $111,000, and for Mr. Korb at approximately $107,667.
 
Pursuant to the waivers, Quanex will also cause Quanex Building Products to enter into a new change-in-control agreement and a severance agreement with each executive. Under the terms of the severance agreement, Quanex Building Products will provide a severance benefit in an amount equal to 12 months for Messrs. Korb, Hammonds and Mannion, 18 months for Messrs. Delaney and Walker and 24 months for Mr. Jean of their respective base salary and a prorated annual bonus equal to the executive’s annual bonus opportunity prorated through the date of severance if the executive’s employment with Quanex Building Products is terminated by Quanex Building Products without “cause” or, if within the one-year period following the closing date, the executive terminates his employment with “good reason,” as each such term will be defined in the severance agreement.
 
If the merger or the spin-off fail to close or if Quanex breaches any of the provisions of the waivers or any other agreement required to be entered into under the terms of the waivers, then the waivers will be void and the change-in-control agreements will remain in full force and effect.
 
Since Mr. Marcucci did not execute a waiver, his change-in-control agreement will remain in full force and effect. A “change in control” is defined generally as (i) an acquisition of securities resulting in an individual or entity or group thereof becoming, directly or indirectly, the beneficial owner of 20% or more of either (a) Quanex’s then-outstanding common stock or (b) the combined voting power of the then-outstanding voting securities of Quanex entitled to vote generally in the election of directors, (ii) a change in a majority of the members of the Board of Directors as of the effective date of the agreement, (iii) generally, a reorganization, merger or consolidation or sale of Quanex or disposition of all or substantially all of the assets of Quanex, or (iv) the approval by the stockholders of Quanex of a complete liquidation or dissolution of Quanex.
 
Upon a change in control, Mr. Marcucci will continue to receive substantially the same compensation and benefits from Quanex (or its successor) that he received before the change. In addition, all options to acquire Quanex common stock held by Mr. Marcucci will immediately vest and be fully exercisable, and all restrictions on restricted Quanex common stock granted to Mr. Marcucci will be removed and the stock will be fully transferable. If during the two-year period following a change in control Mr. Marcucci’s employment is terminated by Quanex (or its successor) other than for “cause” (as defined in the change-in-control agreement) or if Mr. Marcucci terminates his own employment with the company for “good reason” (as defined in the change-in-control agreement), Mr. Marcucci will be entitled to (i) a payment equal to two times

the sum of (a) his base salary and (b) his annual bonus (ii) a prorated annual bonus for the year in which such termination occurs and (iii) continued coverage under Quanex welfare plans until the earlier to occur of (x) the third anniversary of his termination of employment and (y) the date he becomes employed on a full time basis with another employer. The agreement also provides that Mr. Marcucci is entitled to a gross-up payment for any excise taxes that are imposed upon him under Section 4999 of the Code as a result of these or any other payments made by Quanex being deemed to be “excess parachute payments” under Section 280G of the Code.
 
We currently value these benefits (excluding the acceleration of equity awards) for Mr. Marcucci at approximately $867,917.
 
THE MERGER AGREEMENT
 
The following summary of the merger agreement is qualified by reference to the complete text of the merger agreement, which is attached as Annex A and incorporated by reference into this proxy statement. This section of the proxy statement describes the material provisions of the merger agreement but may not contain all of the information about the merger agreement that is important to you. We encourage you to read the merger agreement in its entirety. It is an agreement that establishes and governs the legal relationships among the parties to the agreement with respect to the transactions described in this proxy statement. It is not intended to be a source of factual, business or operational information about any of the parties to the merger agreement. The representations, warranties and covenants made in the agreement are qualified and subject to important limitations. Furthermore, the representations and warranties may be subject to a contractual standard of materiality or material adverse effect applicable to the parties to the agreement that may be different from those that are applicable to you or may be used to allocate risk among the parties to the agreement rather than establishing matters of fact. Some of these representations and warranties may not have been accurate or complete as of any specified date and do not purport to be accurate or complete as of the date of this proxy statement. Accordingly, you should not rely on the representations and warranties as characterizations of the actual state of facts at the time they were made or otherwise.
 
Structure of the Merger
 
Following the spin-off of Quanex’s Building Products Group, on the terms and subject to the conditions of the merger agreement, and in accordance with the DGCL, at the effective time of the merger, Gerdau Delaware will merge with and into Quanex. Quanex will continue as the surviving company and will be a wholly-owned subsidiary of Gerdau. The separate corporate existence of Gerdau Delaware will cease.
 
Timing of Closing
 
The closing of the merger will occur as promptly as practicable following the Quanex stockholder meeting and when all other conditions to the merger, including the completion of the spin-off, other than those conditions that by their nature are to be satisfied at the closing, have been satisfied or waived (or such other date as the parties may agree). However, we cannot assure you when or if the merger will occur.
 
As soon as practicable after the closing of the merger, Gerdau and Quanex will file a certificate of merger with the Secretary of State of the State of Delaware. The effective time of the merger will be the time Gerdau and Quanex file the certificate of merger with the Secretary of State of the State of Delaware or at a later time as may be agreed to and specified in the certificate of merger.
 
Merger Consideration
 
At the effective time of the merger, each outstanding share of Quanex common stock (other than any shares owned directly or indirectly by Gerdau or Quanex and those shares held by dissenting stockholders), together with the rights associated with that share of Quanex common stock under the Third Amended and Restated Rights Agreement dated as of September 15, 2004, between Quanex and Wells Fargo Bank, N.A. as Rights Agent (the “Rights Plan”), collectively will be converted into the right to receive $39.20 in cash, without interest.

Treatment of Quanex Stock Options and Restricted Stock Units
 
At the effective time of the merger, Quanex stock options will become vested and exercisable and will be cancelled. The holder of such Quanex stock options will be entitled to receive an amount in cash equal to: (x) the total number of shares of Quanex common stock subject to the stock option times (y) the excess of (i) the sum of (A) $39.20 and (B) the closing sales price of a share of Quanex Building Products common stock on the NYSE on the distribution date for the spin-off of Quanex’s Building Products Group over (ii) the exercise price per share under the stock option, less any applicable withholding.
 
Each restricted stock unit that has been issued but has not vested prior to the effective time of the merger will become fully vested at the effective time of the merger and will be converted into the right to receive an amount per restricted stock unit equal to the sum of (y) $39.20 and (z) the closing sales price of a share of Quanex Building Products common stock on the NYSE on the distribution date for the spin-off of Quanex’s Building Products Group.
 
See “Interests of Certain Persons in the Merger” beginning on page 33 for a discussion of the treatment of restricted stock pursuant to the terms of the spin-off.
 
Exchange and Payment Procedures
 
At the effective time of the merger, Gerdau will deposit cash in an amount sufficient to pay the merger consideration and the other equity amounts due to each holder of shares of Quanex common stock or other equity holders with a bank or trust company (the “paying agent”) reasonably acceptable to Quanex. As soon as reasonably practicable after the effective time of the merger, the paying agent will send to each holder of Quanex common stock a letter of transmittal and instructions. The letter of transmittal and instructions will tell each holder of Quanex common stock how to exchange their shares for the merger consideration.
 
QUANEX STOCK CERTIFICATES SHOULD NOT BE RETURNED WITH THE ENCLOSED PROXY CARD. QUANEX STOCK CERTIFICATES SHOULD NOT BE SENT TO THE PAYING AGENT WITHOUT A LETTER OF TRANSMITTAL.
 
Holders of Quanex common stock that hold certificates will not be entitled to receive the merger consideration until they surrender their stock certificate or certificates to the paying agent, together with a duly completed and executed letter of transmittal and any other documents as may be reasonably requested by the paying agent. For holders of Quanex common stock that hold their shares in book-entry form, the letter of transmittal will provide specific instructions on how to provide evidence of your ownership of Quanex common stock. The merger consideration may be paid to a person other than the person in whose name the corresponding certificate is registered if the certificate is properly endorsed or is otherwise in the proper form for transfer. In addition, the person who surrenders such certificate must pay any transfer or similar taxes or establish to the satisfaction of the paying agent that such tax has been paid or is not applicable.
 
No interest will be paid or will accrue on the cash payable upon surrender of the certificates. Each of the surviving company and the paying agent will be entitled to deduct and withhold, and pay to the appropriate taxing authorities, any applicable taxes from the merger consideration and the option and restricted stock unit amounts. Any sum which is withheld and paid to a taxing authority by the surviving company or the paying agent will be deemed to have been paid to the person with regard to whom it is withheld.
 
At the effective time of the merger, Quanex’s stock transfer books will be closed, and there will be no further registration of transfers of outstanding shares of Quanex common stock. If, after the effective time of the merger, certificates are presented to the surviving company for transfer, they will be cancelled and exchanged for the merger consideration.
 
If any certificate is lost, or if it has been stolen or destroyed, then before the holder of such certificate will be entitled to receive the merger consideration, such holder will have to make an affidavit of that fact and, if required by Gerdau, post a bond or surety in such reasonable amount as Gerdau may direct as indemnity against any claim that may be made against it with respect to that certificate.

Non-Solicitation Provisions and Acquisition Proposals
 
Quanex has agreed that it will instruct its advisors or representatives not to, directly or indirectly:
 
  •  solicit, initiate or knowingly take any action to facilitate or encourage, whether publicly or otherwise, the submission of any inquiries or the making of any inquiry, proposal or offer or other efforts or attempts that constitutes, or could reasonably be expected to lead to, any “acquisition proposal”;
 
  •  enter into, or participate in any discussions or negotiations regarding, or furnish to any person any non-public information for the purpose of encouraging or facilitating any “acquisition proposal”; or
 
  •  enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or similar agreement with respect to any “acquisition proposal” or enter into any agreement or agreement in principle requiring Quanex to abandon, terminate or fail to consummate the transactions contemplated under the merger agreement or breach its obligations under the merger agreement or agree to do any of the foregoing.
 
An “acquisition proposal” means any inquiry, proposal or offer (other than the transactions contemplated by the merger agreement) from any person or group relating to:
 
  •  any proposal or offer for a merger, consolidation, dissolution, tender offer, recapitalization, reorganization, share exchange, business combination or similar transaction involving Quanex; or
 
  •  any proposal or offer to acquire in any manner, directly or indirectly, over 20% of the equity securities or consolidated total assets (including, without limitation, equity securities of Quanex’s subsidiaries) of Quanex, in each case other than the transactions contemplated under the merger agreement.
 
Notwithstanding the above, Quanex may, to the extent failure to take such actions would reasonably be expected to result in a breach of the fiduciary obligations of the Quanex Board under applicable law, as determined in good faith by the Quanex Board after consultation with outside counsel, in response to a (1) a “superior proposal” or (2) a bona fide, unsolicited written acquisition proposal that Quanex’s Board determines in good faith after consultation with outside counsel and its financial advisor is or is reasonably likely to lead to a superior proposal, furnish information with respect to Quanex to such person that has made a “superior proposal” or potential “superior proposal” and its representatives (provided that Quanex will promptly make available to Gerdau and Gerdau Delaware any material non-public information concerning Quanex or its subsidiaries that is made available to any person given such access which was not previously provided to Gerdau and Gerdau Delaware) pursuant to a customary confidentiality agreement not less restrictive of the


40


Table of Contents

other party than the confidentiality agreement current in place with Gerdau Ameristeel Corporation, but excluding any standstill provisions, and participate in discussions or negotiations with, such person and its representatives regarding any such “superior proposal” or potential “superior proposal.” Quanex will promptly advise Gerdau of the receipt by Quanex of any acquisition proposal or any request for non-public information made by any person or group of persons that has informed Quanex that it is considering making an acquisition proposal or any request for discussions or negotiations with Quanex or its representatives relating to an acquisition proposal (in each case within 48 hours of receipt thereof), and Quanex will provide Gerdau (within such 48 hour time frame) a written summary of the material terms of such acquisition proposal (which shall include the identity of the person or group of persons making the acquisition proposal) and if Quanex determines to begin providing information or to engage in discussions regarding an acquisition proposal. Quanex will keep Gerdau reasonably informed of any material change to the terms and conditions of any acquisition proposal. Quanex agrees not to enter into any confidentiality agreement with any person subsequent to the date of the merger agreement which prohibits Quanex from providing such information to Gerdau.
 
For purposes of the merger agreement, a “superior proposal” means any bona fide written acquisition proposal made by a third party and not solicited to acquire more than 50% of the assets of Quanex and its subsidiaries, taken as a whole but excluding the Building Products Group, pursuant to a tender or exchange offer, a merger, a recapitalization, a consolidation or a sale of its assets, which the Board of Directors of Quanex determines in its good faith judgment (i) to be more favorable from a financial point of view to Quanex stockholders than the merger contemplated with Gerdau and (ii) is reasonably capable of being completed on the terms proposed therein, after taking into account the likelihood and timing of completion and after taking into account all financial, regulatory, legal and other aspects of such proposal.
 
Quanex’s Board of Directors shall generally not be permitted to make a “change in recommendation” regarding the transactions contemplated in the merger agreement unless, prior to obtaining the Quanex stockholder approval, it determines in good faith, after consulting with outside legal counsel, that the failure to do so would reasonably be expected to result in a breach of its obligations under applicable law provided that Quanex cannot make such “change in recommendation” in response to a superior proposal until:
 
  •  at least three business days following Gerdau’s receipt of written notice from Quanex (i) advising Gerdau that the Quanex Board intends to make a “change in recommendation” and the reason for such change, (ii) specifying the terms and conditions of such superior proposal (including the proposed financing for such proposal) and (iii) identifying any party making such superior proposal, and
 
  •  prior to effecting such “change in recommendation” in response to a superior proposal, Quanex and its financial and legal advisors negotiate with Gerdau and Gerdau Delaware in good faith (to the extent that Gerdau and Gerdau Delaware desire to negotiate) to make such adjustments to the terms and conditions of the merger agreement so that the acquisition proposal ceases to constitute a superior proposal.
 
For the purposes of the merger agreement, a “change in recommendation” occurs when the Quanex Board of Directors (i) withdraws, qualifies or modifies or proposes publicly to withdraw, qualify or modify in any manner adverse to Gerdau, its approval or recommendation with respect to the merger agreement and the merger or other transactions contemplated thereby or (ii) approves or recommends any superior proposal made or received after the date of the merger agreement. In determining whether to make a change in recommendation in response to a superior proposal, the Quanex Board of Directors must take into account any changes to the terms of the merger agreement proposed by Gerdau in determining whether such third party acquisition proposal still constitutes a superior proposal.
 
Quanex has also agreed to, and will direct its advisors and representatives to:
 
  •  immediately cease all discussions and negotiations that commenced prior to the date of the merger agreement regarding any acquisition proposals existing on the date of the merger agreement, and to request return or destruction of all confidential information;
 
  •  promptly advise Gerdau of Quanex’s receipt of any acquisition proposal or any request for non-public information made by any person or group of persons that has informed Quanex that it is considering


41


Table of Contents

  making an acquisition proposal or any request for discussions or negotiations with Quanex or its representatives relating to an acquisition proposal, in each case within 48 hours receipt thereof, and Quanex shall provide Gerdau a written summary of the material terms and conditions of the proposal, including the identity of the person or persons making such proposal, and if Quanex determines to begin providing information or engage in discussions regarding an acquisition proposal;
 
  •  keep Gerdau reasonably informed of any material change to the terms and conditions of any acquisition proposal; and
 
  •  not enter into any confidentiality agreement with any person after the date of the merger agreement which prohibits Quanex from providing such information to Gerdau.
 
Financing Commitments; Cooperation of Quanex
 
Gerdau Delaware has represented in the merger agreement that it has sufficient funds to consummate the merger and has provided Quanex a commitment letter from a major bank in order to demonstrate its ability to pay the merger consideration. The ability of Gerdau Delaware to pay the merger consideration is not a condition to the completion of the merger.
 
Quanex has agreed to use its commercially reasonable efforts to, and will cause its subsidiaries and its and their respective officers, employees and representatives to use their commercially reasonable efforts to assist Gerdau and Gerdau Delaware in connection with the arrangement of any financing to be consummated prior to or contemporaneously with the closing of the merger in order for Gerdau to satisfy its obligations under the merger agreement or any refinancing or replacement of any existing, or the arrangement of any new, facility for indebtedness of Quanex and its subsidiaries. Such assistance may include the following:
 
  •  entering into customary agreements, including underwriting and purchase agreements, in connection with the debt financing;
 
  •  participating in meetings, due diligence sessions and road shows;
 
  •  assisting in preparing offering memoranda, rating agency presentations, private placement memoranda, prospectuses and similar documents;
 
  •  using commercially reasonable efforts to obtain comfort letters of accountants and legal opinions; and
 
  •  otherwise making available documents and information relating to Quanex and its subsidiaries.
 
However, such assistance will not be provided if it would:
 
  •  unreasonably interfere with the ongoing operations of Quanex or any of its subsidiaries;
 
  •  cause any representation or warranty in the merger agreement to be breached;
 
  •  cause any condition to the closing of the merger to fail to be satisfied or otherwise cause any breach of the merger agreement or any material agreement to which Quanex or any of its subsidiaries is a party;
 
  •  involve any binding commitment by Quanex or any of its subsidiaries which commitment is not conditioned on the closing of the merger and does not terminate without liability to Quanex or any of its subsidiaries upon the termination of the merger agreement; or
 
  •  in the case of Quanex’s or its subsidiaries’ officers, (i) result in the indemnification protections afforded such officers by Quanex or its subsidiaries not being in full force and effect, (ii) not allow such officers to sign documents, certificates and other instruments in their representative capacity with Quanex or such subsidiary and (iii) result in personal liability attaching to such officers as a result of signing such documents, certificates and other instruments.
 
Employee Benefits
 
For a period of one year after the effective time of the merger, Gerdau will, or will cause the surviving company or its subsidiaries to, offer base salary and bonus opportunities to Quanex employees who are not

covered by a collective bargaining agreement that are in the aggregate equal to the base salary, bonus opportunities and value of the equity incentives being offered to such employees for the fiscal year immediately preceding the fiscal year in which the merger is closed. Generally, Gerdau will grant Quanex employees not covered by a collective bargaining agreement full credit for past service with Quanex for purposes of eligibility, vesting and benefit accrual (other than accrual under certain pension and retiree medical plans) under any employee benefit plans maintained by Gerdau or any of its subsidiaries. Gerdau will take any actions as are necessary so that each Quanex employee who continues as an employee of Quanex not covered by a collective bargaining agreement or any of its subsidiaries will not be subject to preexisting condition exclusions or waiting periods for coverages under any Gerdau benefit plan.
 
Directors’ and Officers’ Indemnification and Insurance
 
Each of Quanex’s certificate of incorporation and bylaws contains a provision eliminating the personal liability of its directors to the company or its stockholders for monetary damages for breach of fiduciary duty as a director to the extent permitted under applicable law. The effect of this provision is to eliminate the personal liability of directors to the company or its stockholders for monetary damages for actions involving a breach of their fiduciary duty. The bylaws of Quanex generally provide for the mandatory indemnification of, and payment of expenses incurred by, its directors and officers to the fullest extent permitted under applicable law. Quanex has obtained directors’ and officers’ liability insurance, which insures against liabilities that its directors and officers may incur in these capacities.
 
Following the effective time of the merger, Gerdau and the surviving company will indemnify and hold harmless, and provide advancements of expenses to, each present and former officer or director of Quanex or any of its subsidiaries. This indemnification will include indemnification against all losses, expenses (including reasonable attorneys’ fees and expenses), claims, damages and liabilities arising out of actions or omissions occurring at or prior to the effective time of the merger (whether asserted or claimed prior to, at or after the effective time of the merger) that are based on the fact that the person is or was a director or officer of Quanex or any of its subsidiaries.
 
For six years after the effective time of the merger, Gerdau will also maintain in effect directors’ and officers’ liability insurance covering acts or omissions occurring prior to the effective time of the merger with respect to those directors and officers of Quanex who were covered by, and on terms and in amounts no less favorable than those of, Quanex’s directors’ and officers’ liability insurance at the time the merger agreement was executed. In no event will the surviving company be required to pay aggregate annual premiums for insurance under this in excess of three times the most recent aggregate annual premium paid by Quanex for such purpose (which most recent aggregate annual premium was $561,500 in the aggregate) provided, further, that if the annual premiums of such insurance coverage exceed such amount, the surviving company will be obligated to obtain a policy with the best coverage available, in the reasonable judgment of the Board of Directors of the surviving company, for a cost up to but not exceeding 300% of the most recent aggregate annual premium paid by Quanex. In addition, for six years after the effective time of the merger, Gerdau will cause the surviving company to maintain in effect fiduciary liability insurance policies for employees who serve or have served as fiduciaries under or with respect to any employee benefit plans described in the disclosure schedules with coverages and in amounts no less favorable than those of the policies of Quanex in effect on the date of the merger agreement.
 
Actions to Consummate the Merger
 
Quanex and Gerdau will cooperate with each other and use their respective reasonable best efforts to take all action to consummate the merger, including complying with Hart-Scott-Rodino Act notice requirements, furnishing information upon request by the other, keeping each other apprised of the status of matters relating to the completion of the transactions and affording representatives of the other party reasonable access to properties, books, contracts, records and personnel. Gerdau and Quanex each agreed to make a filing under the Hart-Scott-Rodino Act with respect to the merger, to request early termination of the waiting period with respect to the merger under the Hart-Scott-Rodino Act and to use their respective reasonable best efforts to promptly respond to any request for additional information under the Hart-Scott-Rodino Act. In addition,

Gerdau has agreed to use its best efforts, after consultation with Quanex, to avoid the entry of any permanent, preliminary or temporary injunction or other order or judgment that would delay, prevent or prohibit consummation of the transactions contemplated by the merger agreement, including:
 
  •  the defense through litigation of any claim brought to delay, prevent or prohibit the transactions contemplated by the merger agreement, and
 
  •  the agreement by Gerdau to sell or dispose of assets or businesses of Gerdau or Quanex if such action is necessary to obtain termination of the waiting period under the Hart-Scott-Rodino Act or to avoid commencement of a proceeding or the issuance of an order that would delay, prevent or prohibit the transactions contemplated by the merger agreement.
 
Gerdau has also agreed to use its best efforts, if an injunction, judgment or decree is issued that would make consummation of the merger unlawful or would delay, prevent or prohibit the transactions contemplated by the merger agreement, to take any and all steps necessary to resist, vacate or modify the injunction, judgment or decree so as to permit consummation on a schedule as close as possible to that contemplated by the merger agreement.

  •  with respect to the obligations of Gerdau and Gerdau Delaware only, the spin-off will have been effected by Quanex.

The merger agreement may be terminated, and the merger may be abandoned in the following ways:
 
  •  at any time prior to the effective time of the merger by mutual written consent of Quanex and Gerdau or by action of their respective boards of directors;

  •  by Gerdau, in the event that the Quanex Board of Directors (i) shall have effected a change in recommendation to the Quanex stockholders or (ii) fails publicly to reaffirm its adoption and recommendation of the merger agreement, the merger or the other transactions contemplated by the merger agreement within ten business days of receipt of a written request by Gerdau to provide such reaffirmation following an acquisition proposal; or

STOCKHOLDER PROPOSALS
 
If the merger agreement described in Proposal 1 is approved and adopted and the merger is completed, we will no longer have any public stockholders and we will not hold an annual meeting of stockholders in 2008. However, if the merger is not completed for any reason, we expect to hold a 2008 Annual Meeting of Stockholders in the second calendar quarter of 2008. Under the rules of the Securities and Exchange Commission, if a stockholder wants us to include a proposal in our proxy statement and form a proxy for presentation at our 2008 Annual Meeting it must have been received by us at our principal executive offices by September 21, 2007. Under our bylaws, if a stockholder has a proposal that they would like us to consider at the 2008 Annual Meeting or if a stockholder would like to nominate an individual for a position on the Board of Directors, the proposal must be submitted not more than 180 days (October 1, 2007) nor less than 60 days (December 29, 2007) prior to February 27, 2008, the anniversary date of the 2007 Annual Meeting. In the event that the date of the Annual Meeting is more than 45 days (which for the 2008 Annual Meeting would be April 12, 2008) later than the anniversary date of the immediately preceding Annual Meeting, notice by the stockholder to be timely must be received not later than the close of business on the tenth day following the earlier of the date on which a written statement setting forth the date of the Annual Meeting was mailed to stockholders or the date on which it is first disclosed to the public.

4.2 Exchange of Shares for Merger Consideration.
 
(a) Exchange of Certificates.  Parent shall select a bank or trust company in the United States reasonably acceptable to the Company to act as the paying agent hereunder (the “Paying Agent”). At the Effective Time, Parent shall deposit with the Paying Agent for the benefit of the holders of certificates, which immediately prior to the Effective Time represented Shares (the “Certificates”), the Merger Consideration, (the “Exchange Fund”), payable pursuant to Section 4.1(c) in exchange for outstanding Shares.
 
(b) Exchange Procedures.  
 
(i) As soon as reasonably practicable after the Effective Time, the Paying Agent will mail to each holder of record of a Certificate whose Shares were converted into the right to receive the Merger Consideration, (A) a letter of transmittal (which will specify that delivery will be effected, and risk of loss and title to the Certificates will pass, only upon proper delivery of the Certificates to the Paying Agent and will be in such form and have such other provisions as Parent and the Company may specify consistent with this Agreement) and (B) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration.
 
(ii) After the Effective Time, upon surrender of a Certificate for cancellation to the Paying Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate will be entitled to receive in exchange therefor the Merger Consideration that such holder has the right to receive therefor pursuant to the provisions of this Article IV, and the Certificate so surrendered will forthwith be cancelled. In the event of a transfer of ownership of Shares that are not registered in the transfer records of the Company, payment may be issued to a person other than the person in whose name the Certificate so surrendered is registered (the “Transferee”) if such Certificate is properly endorsed or otherwise in proper form for transfer and the Transferee pays any transfer or other taxes required by reason of such payment to a person other than the registered holder of such Certificate or establishes to the satisfaction of the Paying Agent that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 4.2(b), each Certificate will be deemed at any time after the Effective Time to represent only the right to receive, upon such surrender, the Merger Consideration that the holder thereof has the right to receive in respect of such Certificate pursuant to the provisions of this Article IV. No interest will be paid or will accrue on any cash payable to holders of Certificates pursuant to the provisions of this Article IV.
 
4.3 Return and Investment of Exchange Fund.
 
(a) Any portion of the Exchange Fund that remains undistributed to the former stockholders of the Company for 15 months after the Effective Time shall be delivered to the Surviving Entity upon demand of the Surviving Entity, and any former stockholders of the Company who have not theretofore complied with this Article IV shall thereafter look only to the Surviving Entity for payment of their claim for the Merger Consideration; provided, that such former stockholder of the Company shall have no greater rights against the Surviving Entity than may be accorded to general creditors of the Surviving Entity under applicable Laws. None of the Company, Parent or the Surviving Entity shall be liable to any holder of Shares for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.
 
(b) The Paying Agent shall invest the Exchange Fund as directed by Parent; provided, that such investments shall be in obligations of or guaranteed by the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker’s acceptance of commercial banks with capital exceeding $10 billion and provided that such investments shall be made in such a manner so as not to impair the availability of the Merger Consideration for payment on the Shares when required.

4.5 Lost Certificates.  If any Certificate shall have 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 required by Parent, the posting by such person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will deliver in exchange for such lost, stolen or destroyed Certificate the Merger Consideration to which such person is entitled pursuant to Section 4.1 with respect to Shares formerly represented thereby.
 
4.6 Withholding Rights.  Each of the Surviving Entity and Parent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares and Company Options such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), and the rules and regulations promulgated thereunder, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by the Surviving Entity or Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holders of Shares and Company Options in respect of which such deduction and withholding was made by the Surviving Entity or Parent, as the case may be.
 
4.7 Closing of the Company Transfer Books.  At the Effective Time, the stock transfer books of the Company shall be closed and no transfer of Shares shall thereafter be made. If, after the Effective Time, Certificates are presented to the Surviving Entity, they shall be canceled and exchanged as provided in this Article IV.
 
4.8 Dissenters’ Shares.  Notwithstanding any provision of this Agreement to the contrary, Shares that are issued and outstanding immediately prior to the Effective Time and held by holders of such Shares who exercise appraisal rights with respect thereto in accordance with applicable provisions of the DGCL, including, without limitation, Section 262 thereof (the “Dissenters’ Shares”) will not be exchangeable for the right to receive the Merger Consideration, and holders of such Dissenters’ Shares will be entitled to receive payment of the appraised value of such Dissenters’ Shares in accordance with those provisions unless and until such holders fail to perfect or effectively withdraw or lose their rights to appraisal and payment under the DGCL. If, after the Effective Time, any such holder fails to perfect or effectively withdraws or loses such rights to appraisal and payment under the DGCL, such Dissenters’ Shares will thereupon be treated as if they had been converted into and have become exchangeable for, at the Effective Time, the right to receive the Merger Consideration, without any interest thereon. The Company shall give Parent prompt notice of any demands received by the Company for appraisals of Shares. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal or offer to settle or settle any such demands. Notwithstanding any provision of this Agreement to the contrary, if Parent or the Company abandon or are finally enjoined or prevented from carrying out the Merger and the other transactions contemplated under this Agreement, the right of each holder of Dissenters’ Shares to receive payment of the appraised value of Shares as provided herein shall terminate, effective as of the time of such abandonment, injunction, prevention or rescission.
 
4.9 Company Options.  
 
(a) At the Effective Time, each option to purchase Shares granted under the Stock Plans that is outstanding immediately prior to the Effective Time (a “Company Option”) shall become fully vested and exercisable, and shall be cancelled and entitle the holder thereof to receive, as soon as reasonably practicable after the Effective Time (but in no event more than three business days following the Effective Time), an amount in cash equal to (x) the total number of shares of Company Common Stock subject to the Company Option times (y) the excess of (i) the sum of (A) the Merger Consideration and (B) the closing sales price of a share of Spinco Common Stock on the Distribution Date as reported on the Exchange over (ii) the exercise price per share under such Company Option (the terms “Spinco Common Stock,” “Distribution Date” and “Exchange” being defined in the Distribution Agreement attached hereto as Exhibit C-1 (the “Distribution Agreement”)), less any applicable withholding.
 
(b) At the Effective Time, each restricted stock unit in respect of a share of Company Common Stock (collectively, the “RSUs”) shall become fully vested and shall be converted into the right of each RSU holder to receive, as soon as reasonably practicable after the Effective Time (but in no event more than three business days following the Effective Time), an amount per RSU equal to the sum of (y) the Merger Consideration and (z) the closing sales price of a share of Spinco Stock on the Distribution Date as reported on the Exchange.

The Company shall, and shall direct its Representatives to, cease immediately all discussions and negotiations that commenced prior to the date of this Agreement regarding any Acquisition Proposal existing on the date of this Agreement and shall use its (and will cause the Company Representatives to use their) commercially reasonable efforts to require the other parties thereto to promptly return or destroy in accordance with the terms of such agreement any confidential information previously furnished by the Company, its Subsidiaries or its Representatives thereunder.
 
Notwithstanding anything to the contrary set forth in this Agreement the Company may, to the extent failure to do so would reasonably be expected to result in a breach of the fiduciary obligations of the Company Board under applicable Law, as determined in good faith by the Company Board after consultation with outside counsel, in response to (1) a Superior Proposal (as defined below) or (2) a bona fide, unsolicited written Acquisition Proposal that the Company Board determines in good faith after consultation with outside counsel and its financial advisor is or is reasonably likely to lead to a Superior Proposal (any such Acquisition Proposal, a “Potential Superior Proposal”), (x) furnish information with respect to the Company to the Person making such Superior Proposal or Potential Superior Proposal and its Representatives (provided that the Company shall promptly make available to Parent and Merger Sub any material non-public information concerning the Company or its Subsidiaries that is made available to any Person given such access which was not previously made available to Parent and Merger Sub) pursuant to a customary confidentiality agreement not less restrictive of the other party than the Confidentiality Agreement, dated July 17, 2007, between Gerdau Ameristeel Corporation and the Company, but excluding any “standstill” provisions (the “Confidentiality Agreement”) and (y) participate in discussions or negotiations with such Person and its Representatives regarding any such Superior Proposal or Potential Superior Proposal. The Company shall promptly advise Parent of the receipt by the Company of any Acquisition Proposal or any request for non public information made by any Person or group of Persons that has informed the Company it is considering making an Acquisition Proposal or any request for discussions or negotiations with the Company or the Company Representatives relating to an Acquisition Proposal (in each case within 48 hours of receipt thereof), and the Company shall provide to Parent (within such 48 hour time frame) a written summary of the material terms of such Acquisition Proposal (it being understood that such material terms shall include the identity of the Person


A-22


Table of Contents

or group of Persons making the Acquisition Proposal) and if the Company determines to begin providing information or to engage in discussions regarding an Acquisition Proposal. The Company shall keep Parent reasonably informed of any material change to the terms and conditions of any Acquisition Proposal. The Company agrees that it and its Subsidiaries will not enter into any confidentiality agreement with any Person subsequent to the date hereof which prohibits the Company from providing such information to Parent.
 
(b) No Change in Company Recommendation or Alternative Acquisition Agreement.  The Company Board and each committee thereof shall not:
 
(i) except as expressly permitted by this Section 6.2, withdraw or modify (or publicly propose to withdraw or modify), in a manner adverse to Parent, the approval or recommendation by the Company Board or any committee thereof with respect to this Agreement and the Merger and other transactions contemplated hereby;
 
(ii) cause or permit the Company to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or similar agreement (an “Alternative Acquisition Agreement”) providing for the consummation of a transaction contemplated by any Acquisition Proposal (other than a confidentiality agreement entered into in the circumstances referred to in Section 6.2(a)); or
 
(iii) except as expressly permitted by this Section 6.2, approve, recommend or propose publicly to approve or recommend any Acquisition Proposal.
 
Notwithstanding anything to the contrary set forth in this Agreement, at any time prior to obtaining the Company Stockholder Approval, the Company Board may withdraw, qualify or modify or propose publicly to withdraw, qualify or modify in any manner adverse to Parent, its approval or recommendation with respect to this Agreement and the Merger and other transactions contemplated hereby or approve or recommend any Superior Proposal made or received after the date of this Agreement, if the Company Board determines in good faith, after consultation with outside counsel, that failure to do so would reasonably be expected to result in a breach of its obligations under applicable Law (a “Change in Company Recommendation”); provided, however, that no Change in Company Recommendation may be made in response to a Superior Proposal until three business days (the “Notice Period”) following Parent’s receipt of written notice from the Company (an “Adverse Recommendation Notice”) (x) advising Parent that the Company Board intends to make such Change in Company Recommendation and the reason for such change, (y) specifying the material terms and conditions of such Superior Proposal (including the proposed financing for such proposal) and (z) identifying any party making such Superior Proposal; provided further prior to effecting such Change in Company Recommendation in response to a Superior Proposal, the Company shall, and shall cause its legal and financial advisors to, during the Notice Period, negotiate with Parent and Merger Sub in good faith (to the extent Parent and Merger Sub desire to negotiate) to make such adjustments to the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal. In the event that during the Notice Period any revisions are made to the Superior Proposal to which the proviso in this Section 6.2(b) applies and the Company Board in its good faith judgment determines such revisions are material (it being agreed that any change in the purchase price in such Superior Proposal shall be deemed a material revision), the Company shall be required to deliver a new Adverse Recommendation Notice to Parent and Merger Sub and to comply with the requirements of this Section 6.2(b) with respect to such new written notice, except that the Notice Period shall be reduced to two business days. In determining whether to make a Change in Company Recommendation in response to a Superior Proposal, the Company Board shall take into account any changes to the terms of this Agreement proposed by Parent (in response to an Adverse Recommendation Notice or otherwise) in determining whether such third party Acquisition Proposal still constitutes a Superior Proposal.
 
(c) Certain Permitted Disclosure.  Nothing contained in this Agreement shall be deemed to prohibit the Company from taking and disclosing to its stockholders a position with respect to a tender offer contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act or from making any other disclosure to the Company’s stockholders or the general public if, in the good faith judgment of the Company Board, after consultation with outside counsel, failure to so disclose would reasonably be expected to result in a breach of its fiduciary duties under applicable Law; provided, however, that neither the Company nor the Company


A-23


Table of Contents

Board (or any committee thereof) shall be permitted to recommend that the Company stockholders tender any securities in connection with any tender or exchange offer (or otherwise approve, endorse or recommend any Acquisition Proposal), unless in each case, in connection therewith, the Company Board effects a Change in Company Recommendation; provided further that any such disclosure (other than a “stop, look and listen” communication or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) shall be deemed to be a Change in Company Recommendation unless the Company Board expressly reaffirms the Company Recommendation at least two business days prior to the Company Stockholders Meeting if Parent has delivered to the Company a written request to so reaffirm at least 48 hours (or if 48 hours is impracticable, as far in advance as is practicable) prior to the time such reaffirmation is to be made.

(e) The provisions of this Section 6.9 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties, their heirs and their representatives and are in addition to, and not in substitution for, any other rights to indemnification that any such person may have by contract or otherwise. If any Indemnified Party is required to bring any action to enforce rights or to collect moneys due under this Agreement and is successful in such action, Parent and the Surviving Entity shall reimburse such Indemnified Party for all of its expenses reasonably incurred in connection with bringing and pursuing such action including, without limitation, reasonable attorneys’ fees and costs.

November 18, 2007
The Board of Directors
Quanex Corporation
1900 West Loop South
Suite 1500
Houston, TX 77027
 
Dear Members of the Board of Directors:
 
We understand that Quanex Corporation, a Delaware corporation (the “Company”), Gerdau S.A., a corporation organized under the laws of the Federative Republic of Brazil (“Parent”), and Gerdau Delaware, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), propose to enter into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, among other things, Merger Sub will be merged with and into the Company (the “Merger”). We understand that prior to the Merger, the Company will spin off or otherwise dispose of its business involving the manufacture and sale of aluminum sheet and engineered materials and components primarily used in the United States building products market (the “Buildings Products Business”). We understand that as a result of the Merger, among other things, each share of the Company’s common stock, par value $0.50 per share (“Company Common Stock”), together with the associated Right (as defined in the Merger Agreement; each share of Company Common Stock together with the associated Right being hereinafter referred to as a “Share” or, collectively, “Shares”), issued and outstanding immediately prior to the effective time of the Merger, other than any (i) shares of Company Common Stock owned directly by the Company as treasury stock or by the Parent or Merger Sub and in each case not held on behalf of third parties, or (ii) Dissenters’ Shares (as defined in the Merger Agreement; the Dissenters’ Shares and shares referred to in clause (i) of this sentence are collectively referred to as the “Excluded Shares”), shall be automatically converted into the right to receive $39.20 in cash (the “Merger Consideration”). The terms and conditions of the Merger are set out more fully in the Merger Agreement.
 
You have requested our opinion as of the date hereof as to the fairness, from a financial point of view, to the holders of the Shares (other than holders of Excluded Shares) of the Merger Consideration to be paid to such holders in the Merger. In connection with this opinion, we have:
 
(i) Reviewed the financial terms and conditions of the draft, dated November 18, 2007 of the Merger Agreement (the “Draft Merger Agreement”);
 
(ii) Analyzed certain publicly available historical business and financial information relating to the Company;
 
(iii) Reviewed various financial forecasts and other data provided to us by the management of the Company relating to the business and prospects of the Company after giving effect to the disposition of the Building Products Business;
 
(iv) Held discussions with members of the senior management of the Company with respect to the business and prospects of the Company after giving effect to the disposition of the Building Products Business;

Table of Contents

(v) Reviewed public information with respect to certain other companies in lines of business we believe to be generally comparable to the business of the Company after giving effect to the disposition of the Building Products Business;
 
(vi) Reviewed the financial terms of certain business combinations involving companies in lines of business we believe to be generally comparable to the business of the Company after giving effect to the disposition of the Building Products Business;
 
(vii) Reviewed the historical stock prices and trading volumes of the Company Common Stock; and
 
(viii) Conducted such other financial studies, analyses and investigations as we deemed appropriate.
 
We have relied upon the accuracy and completeness of the foregoing information, and have not assumed any responsibility for any independent verification of (and we have not independently verified) such information or any independent valuation or appraisal of any of the assets or liabilities of the Company or concerning the solvency or fair value of the Company. With respect to financial forecasts, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of the Company as to the future financial performance of the Company. We assume no responsibility for and express no view as to such forecasts or the assumptions on which they are based.
 
Further, our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof. We assume no responsibility for updating or revising our opinion based on circumstances or events occurring after the date hereof. We do not express any opinion as to the price at which shares of Company Common Stock may trade at any time subsequent to the announcement of the Merger.
 
In rendering our opinion, we have assumed that the Merger Agreement will be identical in all material respects to the Draft Merger Agreement reviewed by us and that the Merger will be consummated on the terms described in the Merger Agreement, without any waiver or modification of any material terms or conditions of the Merger Agreement. We have further assumed that obtaining the necessary regulatory approvals and contractual consents for the Merger and the disposition of the Building Products Business will not have an adverse effect on the Company or the Merger. In addition, we have assumed that the representations and warranties contained in the Merger Agreement and all agreements related thereto are true and complete in all material respects. We do not express any opinion as to any tax or other consequences that might result from the Merger or the disposition of the Building Products Business, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that the Company has obtained such advice as it deemed necessary from qualified professionals. In addition, we express no opinion about the fairness of the amount or nature of, or any other aspect of, the compensation to any of the Company’s officers, directors or employees, or any class of such persons, relative to the Merger Consideration to be paid to public stockholders of the Company or otherwise.
 
In rendering our opinion, we have assumed that the stockholders of the Company prior to the consummation of the Merger (and not the owners of the Company after giving effect to the Merger) will either own or be entitled to receive the proceeds of the disposition of the Building Products Business. We express no opinion as to the value of the Building Products Business or as to the fairness or any other aspect of the disposition of the Building Products Business.
 
Lazard Frères & Co. LLC (“Lazard”) is acting as investment banker to the Board of Directors in connection with the Merger and will receive a fee for its services, a substantial portion of which is payable upon consummation of the Merger. Lazard will also be entitled to receive a fee in connection with the disposition by the Company of the Building Products Business (a “BP Separation Fee”). If the disposition of the Buildings Products Business is accomplished through a spin-off, split-off or similar transaction, and Lazard serves as the resulting entity’s investment banker in connection with a subsequent sale, merger, consolidation or business combination transaction (a “Second Stage Transaction”) within 18 months following the disposition, an additional fee would be payable to Lazard which would be reduced by an amount equal to 50% of the BP Separation Fee received by Lazard. In addition, in the ordinary course of their respective businesses,

affiliates of Lazard and LFCM Holdings LLC (an entity indirectly owned in large part by managing directors of Lazard) may actively trade securities of the Company for their own accounts and for the accounts of their customers and, accordingly, may at any time hold a long or short position in such securities.
 
Our engagement and the opinion expressed herein (which has been approved by our opinion committee) are for the benefit of the Board of Directors in connection with its consideration of the Merger. Our opinion does not address the relative merits of the Merger as compared to other business strategies or transactions that might be available with respect to the Company or the underlying business decision by the Company to engage in the Merger, and is not intended to and does not constitute a recommendation to any holder of Company Common Stock as to how such holder should vote with respect to the Merger or any matter relating thereto.
 
Based on and subject to the foregoing, we are of the opinion that, as of the date hereof, the Merger Consideration to be paid to holders of the Shares (other than holders of Excluded Shares) in the Merger is fair to such holders from a financial point of view.
 
Very truly yours,
 
    LAZARD FRÈRES & CO. LLC

ANNEX C
 
Section 262 of the Delaware General Corporation Law
 
§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 §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 §251 (other than a merger effected pursuant to §251(g) of this title), §252, §254, §257, §258, §263 or §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 §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 §§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.
 
(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under §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-1


Table of Contents

(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 §228 or §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, 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 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.
