                                 PROXY STATEMENT
                       -----------------------------------

          This Proxy  Statement is furnished in connection with the solicitation
by the Board of Directors of Cytogen Corporation (also referred to in this Proxy
Statement as the "Company",  "Cytogen",  "we" or "us") of proxies to be voted at
our Annual Meeting of Stockholders  to be held on Tuesday,  June 18, 2002 at the
Radisson Hotel,  Route One at Ridge Road,  Princeton,  New Jersey at 11:00 a.m.,
local time, and at any adjournment or adjournments thereof. Holders of record of
our common stock, $.01 par value per share, as of the close of business on April
22,  2002,  will be entitled to notice of and to vote at the Annual  Meeting and
any adjournment or adjournments  thereof. As of that date, there were 82,512,259
shares of common stock issued and  outstanding  and entitled to vote. Each share
of common  stock is entitled to one vote on any matter  presented  at the Annual
Meeting.  The aggregate  number of common stock votes entitled to be cast at the
Annual Meeting is 82,512,259.  The holders of common stock will vote as a single
class for all proposals.

         If proxies in the accompanying form are properly executed and returned,
the  shares of common  stock  represented  thereby  will be voted in the  manner
specified  therein.  If not  otherwise  specified,  the  shares of common  stock
represented by the proxies will be voted:

         (i)  FOR, the election of the six nominees named below as directors;

         (ii) FOR, a proposal to amend, as required, our 1995 Stock Option Plan,
         the "1995 Plan", our 1999 Non-Employee  Director Stock Option Plan, the
         "Director  Plan",  and our By-Laws,  the "By-Laws",  as applicable,  to
         provide that without the approval of a majority of our stockholders, we
         shall not:

              (a) grant stock appreciation rights with an exercise price that is
                  less  than the fair  market  value  of the  underlying  common
                  stock; or

              (b) effectively amend or replace certain outstanding  equity-based
                  awards in a manner that would result in lower exercise prices,
                  accelerated  vesting  schedules or the issuance of  restricted
                  stock (as further described below); and

         (iii) in the  discretion  of the persons  named in the enclosed form of
         proxy, on any other proposals which may properly come before the Annual
         Meeting or any adjournment or adjournments thereof.

         Any  stockholder  who has  submitted  a proxy may revoke it at any time
before it is voted, by written notice addressed to and received by our Corporate
Secretary,  by  submitting  a duly  executed  proxy  bearing a later  date or by
electing  to vote in person at the  Annual  Meeting.  The mere  presence  at the
Annual Meeting of the person  appointing a proxy does not,  however,  revoke the
appointment.

         The presence, in person or by proxy, of holders of shares of our common
stock in the aggregate having a majority of the votes entitled to be cast by the
holders of common stock at the Annual  Meeting,  shall  constitute a quorum with
respect to all  matters  presented.  The  affirmative  vote by the  holders of a
plurality of the shares of common  stock  represented  at the Annual  Meeting is
required for the election of directors,  provided a quorum of such  stockholders
is present in person or by proxy.  All actions  proposed  herein  other than the
election of directors  may be taken upon the  affirmative  vote of  stockholders
possessing a majority of the requisite  voting power  represented  at the Annual
Meeting, provided a quorum is present in person or by proxy.

         Abstentions  are included in the shares  present at the Annual  Meeting
for purposes of  determining  whether a quorum is present,  and are counted as a
vote against for purposes of determining whether a proposal is approved.  Broker
non-votes  (when  shares  are  represented  at the  Annual  Meeting  by a  proxy
specifically conferring only limited authority to vote on certain matters and no
authority to vote on other  matters) are  included in the  determination  of the
number of shares  represented  at the Annual Meeting for purposes of determining
whether a quorum is present,  but are not counted  for  purposes of  determining
whether a proposal has been approved and thus have no effect on the outcome.

         This Proxy  Statement,  together  with the related proxy card, is being
mailed  to our  stockholders  on or about  May 9,  2002.  The  Annual  Report to
Stockholders  of the Company for the year ended  December  31,  2001,  including
financial statements,  is being mailed together with this Proxy Statement to all
stockholders  of record as of April 22,  2002.  In  addition,  we have  provided
brokers,  dealers,  banks,  voting trustees and their nominees,  at our expense,
with  additional  copies of the Annual Report so that such record  holders could
supply such materials to beneficial owners as of April 22, 2002.


                              ELECTION OF DIRECTORS

         At the Annual  Meeting,  six directors are to be elected  (which number
shall  constitute  our entire Board of  Directors) to hold office until the 2003
Annual  Meeting of  Stockholders,  and until  their  successors  shall have been
elected and  qualified.  The holders of common  stock,  voting as a class,  will
elect each such director.

         It is the  intention of the persons named in the enclosed form of proxy
to vote the stock represented thereby,  unless otherwise specified in the proxy,
for the election as directors of the persons whose names and biographies  appear
below. All such persons are, at present,  members of our Board of Directors.  In
the event any of the nominees should become  unavailable or unable to serve as a
director,  it is  intended  that  votes  will be cast for a  substitute  nominee
designated  by our Board of  Directors.  Our Board of Directors has no reason to
believe that the nominees named will be unable to serve if elected.  Each of the
nominees has  consented to being named in this Proxy  Statement  and to serve if
elected.

         The current members of our Board of Directors who are also nominees for
election to our Board of Directors are as follows:

the Compensation  Committee,  the Nominating Committee and the Audit and Finance
Committee.

The Nominating Committee

         The Nominating  Committee  currently consists of James A. Grigsby,  who
serves  as  Chairman,  and  H.  Joseph  Reiser.  The  Nominating  Committee  was
established  in 1994  and  did not  hold  any  meetings  in  2001.  The  primary

risk  management,  the  adequacy of  financial  and  accounting  procedures  and
internal  controls on a periodic  basis.  The Audit  Committee  also reviews and

operating  requirements and strategic  objectives.  The  responsibilities of the
Audit Committee are more fully set forth in the Audit Committee  Charter adopted
by the Audit Committee May 16, 2000, a copy of which was filed as an Appendix to
our Proxy Statement  filed with the Securities and Exchange  Commission on April
30, 2001.

         The Nasdaq  National  Market has adopted  requirements  relating to the
independence  of  members of the audit  committees  of  companies  traded on the
market.  Our Audit Committee  members meet the requirements of that rule, except
that members may not have been  employees of the Company  within the three prior
years. Dr. Bagalay served, at the request of the Board of Directors,  as interim
Chief  Executive  Officer from January  1998  through  August 1998,  pending the
recruitment  of a permanent  CEO,  and was deemed to be an employee  during this
period.  The new rules permit one member of an audit  committee to remain on the
committee   even  if  the   independence   criteria   are  not  met  in  certain
circumstances. In accordance with these rules, our Board of Directors determined
that, given his financial  expertise and judgment,  and the brief period of time
which he  served  as an  employee  upon the  Board of  Director's  request,  Dr.
Bagalay's  continued  service on the Audit Committee is in our best interest and
in the best interests of our stockholders.

         Except as noted above,  each Audit  Committee  member is an independent
member of our Board of Directors as defined in Rule  4200(a)(14) of the National
Association of Securities Dealers' listing standards. As an independent director
of our Board of  Directors,  each  Audit  Committee  member is not an officer or
employee of the  Company or our  subsidiaries  and does not have a  relationship
which,  in the  opinion of our Board of  Directors,  would  interfere  with that
person's exercise of independent  judgement in carrying out the responsibilities
of a director.

Report of the Audit Committee

March 28, 2002

To the Board of Directors of Cytogen Corporation:

         We have reviewed and discussed with  management  the Company's  audited
financial statements as of and for the year ended December 31, 2001.

         Management  is  responsible  for the  Company's  internal  controls and
financial  reporting  process.  The Company's  independent  public  accountants,
Arthur Andersen,  LLP ("Andersen") are responsible for performing an independent
audit  of the  Company's  financial  statements  in  accordance  with  generally
accepted  accounting  principles  and to  issue  a  report  on  those  financial
statements. As appropriate, the Audit Committee reviews, evaluates and discusses
with the  Company's  management,  internal  accounting,  financial  and auditing
personnel and Andersen, the following:

-    the plan  for,  and  Andersen's  report  on,  each  audit of the  Company's
     financial statements;

-    the  Company's  financial  disclosure  documents,  including  all financial
     statements and reports filed with the Securities and Exchange Commission or
     sent to stockholders;

-    management's  selection,  application and disclosure of critical accounting
     policies;

-    changes in the  Company's  accounting  practices,  principles,  controls or
     methodologies;

-    significant  developments or changes in accounting  rules applicable to the
     Company; and

-    the adequacy of the Company's  internal controls and accounting,  financial
     and auditing personnel.

         We have discussed with Andersen the matters required to be discussed by
Statement on Auditing Standards No. 61, Communication with Audit Committees,  as
amended,  by the Auditing Standards Board of the American Institute of Certified
Public  Accountants  ("SAS 61").  SAS 61 requires  Andersen to discuss  with the
Audit Committee, among other things, the following:

-    methods to account for significant unusual transactions;

-    the effect of significant  accounting policies in controversial or emerging
     areas for which there is a lack of authoritative guidance or consensus;

-    the  process  used by  management  in  formulating  particularly  sensitive
     accounting estimates and the basis for Andersen's conclusions regarding the
     reasonableness of those estimates; and

-    disagreements   with   management   over  the   application  of  accounting
     principles,  the  basis  for  management's  accounting  estimates  and  the
     disclosures in the financial statements.

         We have received,  reviewed and discussed the written  disclosures  and
the letter from Andersen  required by Independence  Standard No. 1, Independence
Discussions with Audit  Committees,  as amended,  by the Independence  Standards
Board  ("Independence  Standards Board Standard No. 1"), and have discussed with
Andersen their independence.

         We have considered whether the non audit services provided by Andersen,
as set forth in the section of our Proxy Statement entitled, "Independent Public
Accountant Fees and Other Matters",  are compatible with maintaining  Andersen's
independence.  Independence  Standards  Board  Standard No. 1 requires  auditors
annually  to  disclose  in  writing  all  relationships  that  in the  auditor's
professional opinion may be reasonably thought to bear on independence,  confirm
their perceived independence and engage in a discussion of independence.

         Furthermore,  we have received  representations from Andersen that: (i)
the audit conducted by Andersen was subject to Anderson's quality system for the
U.S.  accounting and auditing practice to provide reasonable  assurance that the
engagement was in compliance  with  professional  standards;  and (ii) there was
appropriate  continuity  of  Andersen  personnel  working  on the  audit and the
availability of national office consultation to conduct the relevant portions of
the audit.


                                       5


         Based on the reviews and discussions referred to above, we recommend to
the  Board of  Directors  that the  financial  statements  referred  to above be
included in the Company's Annual Report on Form 10-K for the year ended December
31, 2001.

Independent Public Accountants Fees and Other Matters

Audit Fees

         Andersen  billed us an  aggregate  of $96,250 in fees for  professional
services  rendered in connection with the audit of our financial  statements for
the most recent fiscal year and the reviews of the financial statements included
in each of our  Quarterly  Reports on Form 10-Q  during  the  fiscal  year ended
December 31, 2001.

Financial Information Systems Design and Implementation Fees

         Andersen  did  not  perform  any  professional  services  for us or our
affiliates  for the fiscal  year ended  December  31,  2001 in  connection  with
financial  information  systems design or  implementation,  the operation of our
information system or the management of our local area network.

All Other Fees

         Andersen  billed us $83,575 for other  services  rendered  for the most
recent fiscal year.

Directors' Compensation

         Each of our  non-employee  directors  receives  an annual  retainer  of
$12,000,  plus $1,500 for each board meeting  attended ($500 if participation is
by  telephone).  Any  non-employee  director  who also chairs a board  committee
receives an additional annual fee of $2,000. Non-employee directors receive $500
for each  committee  meeting  attended,  but receive no additional  retainer for
committee  membership.  Members of the  Nominating  Committee do not receive any
compensation  for serving on that  committee.  The Chairman of the Board (who is
not an employee of the Company) currently receives,  based upon significant time
spent on Company  business,  an  additional  annual  retainer  of  $50,000.  The
additional  retainer  contemplates  four days per month  substantially  given to
Company  business  by the  Chairman.  An amount of $1,500 per day is paid to the
Chairman for additional days in which the significant part of the day is devoted
to Company  matters.  During 2001,  the  Chairman  received  $50,000  under this
arrangement.  In  addition,  the  Chairman  was paid $12,500 in fees during 2001
relating to services to be performed in 2002.

                                       6


         Pursuant to the Director Plan, each  non-employee  director receives an
initial grant of options on the date of appointment  equal to a pro-rata portion
of 20,000 shares of our common stock,  based upon the number of months remaining
from the date of election until the one year anniversary of the preceding annual
meeting.  In  addition,  on  the  day  following  each  annual  meeting  of  the
stockholders,  each  individual who is elected as a non-employee  director shall
automatically  be granted options to purchase 10,000 shares of our common stock.
The  Chairman  of  the  Board,  unless  the  Compensation  Committee  determines
otherwise,  receives an additional grant of 15,000 options to purchase shares of
our common stock on the date of each annual  meeting.  Options granted under the
Director  Plan are  exercisable  at a price equal to the average of the high and
low sale prices of the common stock as reported on the Nasdaq National Market on
the date of grant and vest in full (i.e., first become exercisable) at the first
anniversary of the option grant date. Each director's  outstanding  options also
become  immediately  exercisable in full: (i) upon the occurrence of a change of
control of the Company; (ii) upon death or disability; or (iii) upon resignation
or retirement after age 55.

         In  addition,   at  the  2001  Annual  Meeting  of  Stockholders,   our
stockholders  adopted a proposal  to amend the  Director  Plan to  provide  that
non-employee directors shall receive, at the sole discretion of and after formal
action by our Board of Directors,  such number of shares of common stock that is
equal to each such director's cash compensation (including,  but not limited to,
annual service fees, fees payable for board and committee  meetings attended and
fees for committees chaired), (the "Cash Component"), divided by the fair market
value of our  common  stock  as of the date of  issuance  of such  shares,  (the
"Compensation  Shares"),  which date shall be no earlier  than the date on which
the  applicable  Cash  Component  compensation  becomes  due and  payable by us.
Compensation  Shares  shall not be issued for  services not yet rendered by such
directors to the Company.  Such  amendments to the Director Plan further provide
that in the event the board elects to issue Compensation  Shares,  such eligible
directors  shall receive  Compensation  Shares until,  absent  additional  board
action,  at least such time as: (i) such director owns twenty thousand  (20,000)
shares of our common stock,  excluding options or other rights to acquire shares
of our common stock, whether exercisable or unexercisable; or (ii) if fewer than
20,000  shares are so owned,  such  smaller  number of shares has a fair  market
value of in excess of one hundred  thousand  dollars  ($100,000),  excluding the
value,  if any, of options to purchase  common  stock,  whether  exercisable  or
unexercisable,  or other  rights to acquire  our common  stock.  Upon  achieving
either of such  milestones (i) or (ii) above,  each such director may, at his or
her option,  elect to cease  receiving his or her Cash  Component to which he or
she is entitled in shares of our common stock under the Director Plan; provided,
however,  that such director must make such election by providing notice of such
election to us in a timely manner.  In October 2001, our Board of Directors took
appropriate  actions to  implement  the  payment  of  director  compensation  in
Compensation Shares.

         Each  option  provided  for in  the  Director  Plan  shall  be  granted
automatically  and without  further  action by us, our Board of Directors or our
stockholders.  Promptly  after the date of grant of each option  provided for in
the  Director  Plan,  we shall  cause an option  agreement  to be  executed  and
delivered  to the holder of the option.  No other  options may be granted at any
time under the Director Plan.

         We have prepared an amendment to the Director  Plan that  restricts our
ability,  without the approval of a majority of our  stockholders,  to (a) grant
stock  appreciation  rights  with an  exercise  price that is less than the fair
market value of the underlying common stock; or (b) effectively amend or replace
certain  outstanding  equity-based awards in a manner that would result in lower
exercise  prices,  accelerated  vesting  schedules or the issuance of restricted
stock, as more fully set forth under the heading "PROPOSED AMENDMENT TO THE 1999
NON-EMPLOYEE  DIRECTOR  STOCK  OPTION  PLAN,  THE  1995  STOCK  OPTION  PLAN AND
BY-LAWS."

(1)  Based on an  aggregate  of 747,360  options  granted to  employees in 2001,
     including options granted to Named Executives.

(2)  The exercise price of all stock options granted during the last fiscal year
     is equal to the average of the high and low sale prices of our common stock
     as  reported  on the Nasdaq  National  Market on the  respective  dates the
     options were granted.  Options granted to executive officers generally vest
     over  three  years at the rate of 33.3%  per year  beginning  on the  first
     anniversary  of the date of grant,  subject to  acceleration  under certain
     conditions.  The maximum term of each option  granted is ten years from the
     date of grant.

(3)  These amounts represent certain assumed rates of appreciation  only. Actual
     gains,  if any, on stock option  exercises  and common  stock  holdings are
     dependent on the future  performance  of our common stock and overall stock
     market conditions. There is no assurance that the amounts reflected will be
     realized.

     our subsidiary company, AxCell Biosciences  Corporation,  during 2001, with

     AxCell's  common stock in 2001 and will expire  beginning in September 2010
     to December 2011.

(5)  Ms. Verna resigned from her positions with us effective  February 28, 2002.
     The options  granted to Ms. Verna during 2001 will expire within 90 days of
     the date of her  termination  of employment  with us, or May 28, 2002,  and
     were not, nor will such options be, vested as of such date.

Equity Compensation Plans Not Approved by Security Holders:

          The  following   describes   the  material   features  of  our  equity
compensation  plans that have not been approved by our security holders,  as set
forth in the above table.

          We have  issued  options to  purchase  2,050,000  shares of our common
stock outside of any of our equity  compensation  plans to H. Joseph Reiser, our
President and Chief Executive  Officer,  upon his commencement of his employment
with us in August 1998. Such options: (i) vest from time to time and pursuant to
the  achievement  of certain  milestones  within the  discretion of our Board of
Directors;  (ii) have an exercise price of $1.0937 per share; (iii) terminate on
August  18,  2008;  and  (iv)  are  subject  to  equitable  adjustment  upon the
occurrence of certain  reorganizations,  recapitalizations or similar events. We
have also issued options to purchase  300,000 shares of our common stock outside
of any of our  equity  compensation  plans  to  Lawrence  R.  Hoffman,  our Vice
President and Chief Financial  Officer,  upon the commencement of his employment
with us in July 2000. Such options were granted on July 10, 2000 and vest at the
rate of 33.3% per year beginning on the first  anniversary of the date of grant.
Such options have an exercise price of $10.141 per share,  terminate on July 10,
2010 and are subject to  equitable  adjustment  upon the  occurrence  of certain
reorganizations, recapitalizations or similar events.

          Additionally  we have issued options to purchase  10,000 shares of our
common stock  issued  outside any of our equity  compensation  plans to Kevin G.
Lokay,  upon his  appointment  to our Board of Directors in January  2001.  Such
options have an exercise  price of $6.126 per share,  expire on January 17, 2011
and vested in full on January  17,  2002.  Such  options are subject to the same
equitable  adjustment as are our outstanding  shares of common stock and are not
afforded anti-dilution protection.

          We have also issued an aggregate of 63,630 warrants to purchase shares
of our  common  stock to various  persons  and  entities  in  consideration  for
services  rendered by such persons or entities.  Such  warrants  have a weighted
average  exercise price of $2.27 per share and expire from time to time over the
next three years. All such warrants are immediately exercisable.

          We are  contractually  obligated  to issue  warrants  to  purchase  an
additional  70,000  shares of our common stock to the SCO Group over the next 10
months, which warrants are in consideration for certain services provided by SCO
to us and in addition to warrants to purchase  14,000 shares of our common stock
previously  so  issued to SCO and which  are  included  in the above  referenced
warrants.  Such warrants shall be issued at the beginning of each month, have an
exercise  price equal to 50% above our closing  stock price on the last business
day of the preceeding month and will expire three years from the date of grant.

Employment   Contracts,   Termination   of  Employment   and   Change-in-Control
Arrangements


         We have executed indemnification  agreements with each of our executive
officers  and  directors  pursuant  to which we have  agreed to  indemnify  such
parties to the full extent permitted by law, subject to certain  exceptions,  if
any such party  becomes  subject to an action  because such party is a director,
officer,  employee, agent or fiduciary of the Company. In general, our employees
are covered by confidentiality agreements.

         We entered into an employment  agreement with H. Joseph Reiser,  Ph.D.,
our  President  and Chief  Executive  Officer,  which  provides  for bonuses and
vesting of options  for the  purchase  of shares of our  common  stock  based on
continued employment and on the achievement of performance objectives defined by
our Board of Directors.  Dr. Reiser is also entitled to one year's severance pay
equal to his base salary, along with medical and insurance benefits for the same
period, if he is dismissed for reasons other than cause.

         We have  also  entered  into  Executive  Change  of  Control  Severance
Agreements with each of Messrs. Becker,  Goeckeler and Hoffman and Ms. Kaminsky,
which  provide,  generally,  for the payment of twelve  months' base  salary,  a
pro-rata portion of such officer's bonus  compensation,  the continuation of all
benefits,  reasonable  Company-paid  outplacement  assistance  and certain other
accrued rights, in the event such officer's  employment with us is terminated in
connection with a change in control as set forth therein.

Compensation Committee Interlocks And Insider Participation

         During  2001,  our  Compensation   Committee  consisted  of  Robert  F.
Hendrickson, who served as Chairman, Kevin G. Lokay and S. Leslie Misrock (until
Mr.  Misrock  resigned July 18, 2001).  There are no, and during 2001 there were
no,  Compensation  Committee  interlocks.  In  June  1999,  we  entered  into an
agreement  with  S.  Leslie  Misrock,   and  others,  to  reacquire  rights  for
immunotherapy to our PSMA technology by acquiring Prostagen,  Inc., of which Mr.
Misrock  was a  principal  holder.  Mr.  Misrock  was  elected  to our  Board of
Directors in August 1999. In connection  with the  acquisition,  Mr. Misrock and
other shareholders of Prostagen received shares of our common stock. We may also
issue additional shares upon completion of certain  milestones,  including up to
450,000  shares of our common stock upon the  satisfactory  termination of lease
obligations  assumed in the  acquisition;  up to 500,000  shares of common stock
upon beneficial  resolution of other  contractual  arrangements  entered into by
Prostagen;  and up to an  additional  $4.0 million in shares of our common stock
(calculated  at the time of issuance) if certain  milestones are achieved in our
dendritic  cell  therapy  and  PSMA  development   programs.  We  are  currently
determining whether the initial $2.0 million milestone has been met in the first
quarter of 2002 based on the  progress of the  dendritic  cell  prostate  cancer
clinical  trials  being  conducted  by  Northwest  Biotherapeutics  Inc.  (NWBT,
NASDAQ).

         In addition,  Mr.  Misrock,  until his death,  was a senior  partner at
Pennie  and  Edmonds,  a New York  based  intellectual  property  law firm  that
represents us in certain intellectual property matters.

Report of the Compensation Committee of the Board of Directors

Policy

         The Compensation Committee of the Board of Directors is responsible for
oversight of our executive  compensation program. The Compensation  Committee is
composed  entirely of  independent,  non-employee  directors.  The  Compensation
Committee makes  recommendations  to the full Board of Directors on compensation
policy and as to specific compensation actions,  except where independent action
by the Compensation Committee is appropriate.

         Our compensation  program,  both for our executive  officers as well as
for all  employees,  is  based  on the  philosophy  that  the  interests  of the
employees  should be closely  aligned with those of our  stockholders.  Our 2001
executive compensation program was based on the following principles:

-    compensation  opportunities  should attract the best talent to us, motivate
     individuals  to  perform  at  their  highest  levels,   reward  outstanding
     achievement,  and retain the leadership  and skills  necessary for building
     long-term stockholder value;

-    a portion of total compensation should be at risk of performance; and

-    individual  executives  should be encouraged to manage from the perspective
     of owners of the Company.

         Our 2001 compensation  program  reflected the Compensation  Committee's
assessment  as to  appropriate  treatment on an  individual  basis for the Chief
Executive  Officer  and the other  Named  Executives  compared to the prior year
levels.  We target our overall  compensation  program at the median level of the
biotechnology industry. In addition,  compensation for the Named Executives (and
other   executives),   including   our  CEO,   took  into   account   individual
responsibility and performance as assessed by the Compensation Committee.

         The  compensation  program  includes a combination of competitive  base
salary and benefits,  annual cash bonus  opportunities  and stock option awards.
The 2001  executive  compensation  program and a specific  discussion  as to the
compensation of the CEO are set out below.

Annual Compensation for 2001

         Generally,   annual   compensation  of  executive  officers  under  the
executive   compensation   program  for  2001  consisted  of  salary  and  bonus
components.

Base Salary

         In  December   2000,   the   Compensation   Committee   determined  for
recommendation  to the  full  Board  of  Directors,  base  salaries  and  annual
incentive  opportunities for 2001 for our executives,  including the CEO and the
other Named Executives.

Bonus

         A portion of 2001 executive officer annual compensation opportunity was
based  on  corporate  performance.  The  Compensation  Committee  believes  that
incentive  compensation  should be linked to  corporate  financial  results  and
corporate  goals.  Bonus  opportunity  levels for 2001  performance  were set in
advance of the year at a percentage of base salary, with the total amount of the
bonus  opportunity  dependent on the extent to which  corporate  objectives were
achieved and the amount of cash  available  as  determined  by the  Compensation
Committee.  At year-end,  the  Compensation  Committee  determined the extent to
which our financial and corporate  objectives  had been achieved and applied the
appropriate  bonus percentage to the respective base salary of each of the Named
Executives. The amounts approved on the Compensation Committee's recommendations
were less than target amounts. We issued to each of Mr. Rodwell,  Mr. Goeckeler,
Mr. Hoffman and Ms. Verna,  4,937,  4,909,  8,314 and 5,041 registered shares of
our common stock,  respectively,  as part of each such  individual's  2001 bonus
compensation.


                                       19



Long Term Compensation - Stock Options

         The  Compensation   Committee   believes  that  stock  options  are  an
appropriate   means  to  link  our  employees'   interests  with  those  of  our
stockholders.  Stock  option  awards are designed  primarily  to provide  strong
incentives for superior longer-term performance and continued retention. Because
the  Compensation  Committee  believes that corporate  performance is one of the
principal factors influencing the market value of our common stock, the granting
of stock options to our executive  officers  encourages  them to work to achieve
consistent improvements in corporate performance. Options only have value to the
recipient when the price of our common stock exceeds the exercise  price,  which
is not less than the fair market value of our common stock at the date of grant.

         Option  grants are set taking into account the  comparison of practices
at peer groups,  an  individual's  level of  responsibility  and  furtherance of
corporate objectives,  and the amount and terms of past stock option awards. The
Compensation Committee also took into account in its review of option grants the
fact that we have no other  long  term  incentive  program,  and  believes  that
options are important to retain  executives and promote steps to build long term
value.

Compensation of the Chief Executive Officer

         Dr.  Reiser's  salary  for  2001 was set on the  recommendation  of the
Compensation  Committee  and was  believed  to be an  appropriate  level of base
compensation in view of compensation levels paid by the industry, in view of Dr.
Reiser's experience,  and considering our continuing  accomplishments  under his
leadership  during the year.  The year end bonus in the amount of  $100,000  was
based  on  the  Compensation  Committee's  judgment  as to  achievement  of  his
objectives  compared to a target  amount set by the  Compensation  Committee  in
advance  of the year.  During  2001,  Dr.  Reiser's  salary  was  $315,000.  The
Committee has approved an increase of $10,000 to $325,000 for 2002.

Federal Income Tax Considerations

         Section 162(m) of the Internal Revenue Code of 1986, as amended, or the
"Code,"  generally  disallows a federal income tax deduction to public companies
for certain compensation over $1 million paid to its chief executive officer and
four other most highly compensated  executive  officers.  Certain  compensation,
including  compensation  based on  performance,  is not subject to this limit if
certain  conditions  are  met,  primarily,  that  the  compensation  is based on
objective  performance  criteria  approved  by  stockholders.  The  compensation
payments  must also be made  pursuant to a plan  administered  by a committee of
outside directors.  The Compensation Committee must certify that the performance
goals were achieved before payments can be awarded.

         The  Compensation  Committee  believes that our executive  compensation
program is consistent with the requirements of Section 162(m). Our regular stock
option plans under which options may be granted to executive  officers have been
approved by our  stockholders  and we believe such plans should  qualify for the
exclusion  from the deduction  limits.  Base salary,  annual bonuses and certain
other  compensation  amounts disclosed in the summary  compensation table do not
qualify  for the  exclusion  from  the $1  million  limit  but such  amounts  of
compensation are not expected to exceed the deduction  limits.  The Compensation
Committee will consider appropriate steps in the future,  including  stockholder
approval,  to maintain  deductions for our incentive  compensation  plans to the
greatest extent practical while maintaining flexibility to take actions which it
deems in our best  interests and in the best interests of our  stockholders  but
which may result in certain compensation not qualifying for tax deductions.

         The  Compensation   Committee   believes  that  performance  should  be
rewarded,  that the  financial  interests of the  executive  officers  should be
aligned with the stockholders,  and that compensation should be competitive.  We
have structured the compensation we pay to meet these criteria.

         The  foregoing  report on  compensation  is provided  by the  following
outside directors, who constituted the Compensation Committee as of December 31,
2001.


                                           Robert F. Hendrickson, Chairman

    PROPOSED AMENDMENTS TO THE 1995 STOCK OPTION PLAN, THE 1999 NON-EMPLOYEE
                    DIRECTOR STOCK OPTION PLAN, AND BY-LAWS

The 1995 Stock Option Plan

General

         On March 28,  1995,  the Board of  Directors  approved  and, on May 23,
1995, our stockholders adopted, the 1995 Stock Option Plan, the "1995 Plan". The
1995 Plan  currently  provides for the grant of options to purchase a maximum of
4,502,635 shares of our common stock to eligible employees and consultants.

         The following is a summary description of the 1995 Plan as it currently
exists without giving effect to the proposed amendment,  and is qualified in its
entirety  by the full text of the 1995 Plan.  The full text of the 1995 Plan may
be  obtained by our  stockholders  upon  request to the office of our  Corporate
Secretary.

         A Committee,  designated by our Board of Directors, the "Committee", is
authorized  to, among other things,  interpret and  administer the 1995 Plan, to
select  employees or eligible  consultants  to whom options will be granted,  to
determine the time when options will be granted and the terms and  provisions of
the options  (which may differ from one another),  and to adopt and make changes
in the rules and regulations for carrying out the 1995 Plan. The Committee shall
be  composed of not less than two outside  directors  who are also  non-employee
directors and who are not eligible to participate in the 1995 Plan.

         Our Board of Directors may amend the 1995 Plan, except that stockholder
approval is required  to: (i)  increase  the maximum  number of shares of common
stock that may be issued on  exercise  of options  granted  under the 1995 Plan,
with  certain  exceptions;  (ii) change the  categories  of persons  eligible to
receive  options;  (iii)  increase the limit on the number of shares that may be
granted per optionee;  or (iv) modify the  provisions  of Section  7(a)(i) as it
relates to the  prohibition  of granting  options with an exercise price that is
less than the fair market  value of the  underlying  common stock on the date of
grant.

         Options  may be granted  under the 1995 Plan only to persons who at the
date of grant  either (i) are  employees  or eligible  consultants  or (ii) have
agreed to become  employees or eligible  consultants,  and, in either case,  are
determined by the Committee to be of substantial  importance to us or any of our
subsidiaries.  Options  granted to persons who are not yet employees or eligible
consultants  at the date of grant may not be  exercised  until the  optionee has
become an employee  or eligible  consultant,  and shall  expire if the  optionee
fails to  commence  service as an employee  or  eligible  consultant  within six
months (or such other period as the Committee may  determine)  after the date of
grant.

         The mere grant of an option does not require any consideration from the
optionee.  The  Committee  may, in its  discretion,  provide that payment of the
exercise  price  of an  option  may be made in cash or  check.  Options  will be
exercisable  over a period to be designated by the  Committee,  but not prior to
six months or more than ten years (or five  years for  certain  incentive  stock
options)  after  the  date of  grant.  Except  as  otherwise  determined  by the
Committee,  options  granted under the 1995 Plan will be exercisable  only while
the  optionee is employed by us and within three  months  after  termination  of
employment  generally or within 12 months after  termination  of  employment  by
reason of death or disability.


                                       22




         No  eligible  employee  may be granted  options to  purchase  more than
200,000 shares in any one calendar year. Under the 1995 Plan, eligible Optionees
may be granted  either ISOs or NQSOs.  ISOs are intended to be "incentive  stock
options"  under Section 422 of the Code and NQSOs are those options which do not
qualify under Section 422 of the Code.  Under the Code, the exercise price of an
ISO must be at least  equal to 100% of the fair  market  value of the  shares of
common stock on the date of grant,  although the exercise price of a NQSO may be
less than such fair market value. The aggregate fair market value (determined at
the time an option is  granted) of the common  stock with  respect to which ISOs
are first  exercisable  by an optionee  during any calendar  year may not exceed
$100,000.

         Options granted under the 1995 Plan are not transferable  other than by
will  or by  operation  of  the  laws  of  descent  and  distribution,  and  are
exercisable  to the extent vested at any time prior to the scheduled  expiration
date of the option. In the event of the death of an optionee,  the option may be
exercisable  by his estate.  If an option expires or is cancelled or surrendered
without being  exercised in full, the number of shares as to which the option is
not  exercised  will once again  become  shares as to which new  options  may be
granted. The 1995 Plan became effective as of March 28, 1995, and will remain in
effect for ten years thereafter  (March 28, 2005), or until sooner terminated by
our Board of Directors.

         Unless otherwise determined by our Board of Directors,  our issuance of
shares of stock of any class, or securities  convertible into shares of stock of
any class,  for cash or  property,  or for labor or services  either upon direct
sale or upon the  exercise of rights or warrants to  subscribe  therefor,  or on
conversion of shares or obligations of the Company  convertible into such shares
or other securities, shall not affect, and no adjustment by reason thereof shall
be made with  respect to, the number,  class or price of shares of common  stock
then subject to outstanding options.

         If as a  result  of (i)  our  reorganization  or  liquidation  or  (ii)
reclassification of our capital stock, or (iii) our consolidation or merger with
or into another  corporation,  or sale of all or substantially all the assets of
ours (such  reorganization  or  liquidation or  reclassification  of our capital
stock,  or a  merger,  consolidation  or  sale  of the  type  described  in this
subsection being a "Corporate Transaction") while an option is outstanding,  the
holders of the common  stock become  entitled to receive,  with respect to their
common  stock,  securities or assets other than, or in addition to, their common
stock,  upon  exercise of that  option,  the holder will receive what the holder
would have owned if the holder had exercised the option  immediately  before the
Corporate  Transaction  which occurred while the option was  outstanding and had
not disposed of anything the holder would have  received as a result of that and
all subsequent Corporate Transactions.

The 1999 Non-Employee Director Plan

General

         The  following  is a  summary  description  of  the  1999  Non-Employee
Director Plan,  (the  "Director  Plan"),  as it currently  exists without giving
effect to the proposed  amendment,  and is qualified in its entirety by the full
text of the Director Plan. The full text of the Director Plan may be obtained by
our stockholders upon request to the office of our Corporate Secretary.

         On April 1, 1999,  the Board of  Directors  approved  and,  on June 16,
1999, the stockholders  adopted,  the Director Plan. The Director Plan currently
provides for the grant of options to purchase a maximum of 500,000 shares of our
common stock to non-employee directors, of whom there are five.

                                       24



         Pursuant to the Director Plan, each  non-employee  director receives an
initial grant of options on the date of appointment  equal to a pro-rata portion
of 20,000 shares of our common stock,  based upon the number of months remaining
from the date of election until the one year anniversary of the preceding annual
meeting.  In  addition,  on  the  day  following  each  annual  meeting  of  the
stockholders,  each  individual who is elected as a non-employee  director shall
automatically  be granted options to purchase 10,000 shares of our common stock.
The  Chairman  of  the  Board,  unless  the  Compensation  Committee  determines
otherwise,  receives an additional grant of 15,000 options to purchase shares of
our common stock on the date of each annual  meeting.  Options granted under the
Director  Plan are  exercisable  at a price equal to the average of the high and
low sale prices of the common stock as reported on the Nasdaq National Market on
the date of grant and vest in full (i.e., first become exercisable) at the first
anniversary of the option grant date. Each director's  outstanding  options also
become  immediately  exercisable in full: (i) upon the occurrence of a change of
control of the Company; (ii) upon death or disability; or (iii) upon resignation
or retirement after age 55.

         In  addition,   at  our  2001  Annual  Meeting  of  Stockholders,   our
stockholders  adopted a proposal  to amend the  Director  Plan to  provide  that
non-employee directors shall receive, at the sole discretion of and after formal
action by our Board of Directors,  such number of shares of common stock that is
equal to each such director's cash compensation (including,  but not limited to,
annual service fees, fees payable for Board and committee  meetings attended and
fees for committees chaired),  (the "Cash Component") divided by the fair market
value of our  common  stock  as of the date of  issuance  of such  shares,  (the
"Compensation  Shares"),  which date shall be no earlier  than the date on which
the  applicable  Cash  Component  compensation  becomes  due and  payable by us.
Compensation  Shares  shall not be issued for  services not yet rendered by such
directors to us. Such  amendments to the Director  Plan further  provide that in
the event the Board of  Directors  elects  to issue  Compensation  Shares,  such
eligible Directors shall receive  Compensation  Shares until,  absent additional
board  action,  at least such time as: (i) such  director  owns twenty  thousand
(20,000)  shares of our  common  stock,  excluding  options  or other  rights to
acquire shares of our common stock,  whether  exercisable or  unexercisable;  or
(ii) if fewer than 20,000 shares are so owned, such smaller number of shares has
a fair market  value of in excess of one hundred  thousand  dollars  ($100,000),
excluding  the value,  if any,  of options to  purchase  common  stock,  whether
exercisable or unexercisable,  or other rights to acquire our common stock. Upon
achieving  either of such milestones (i) or (ii) above,  each such director may,
at his or her option,  elect to cease  receiving  his or her Cash  Component  to
which he or she is  entitled  in  shares  of our  common  stock  under the Plan;
provided,  however,  that such  director  must make such  election by  providing
notice of such election to us in a timely manner.  In October 2001, our Board of
Directors  took  appropriate  actions  to  implement  the  payment  of  director
compensation in Compensation Shares.

         Each  option  provided  for in  the  Director  Plan  shall  be  granted
automatically  and without  further  action by us, our Board of Directors or our
stockholders.  Promptly  after the date of grant of each option  provided for in
the  Director  Plan,  we shall  cause an option  agreement  to be  executed  and
delivered  to the holder of the option.  No other  options may be granted at any
time under the Director Plan.

         Options may not be transferred except by will or by the laws of descent
and  distribution  and are exercisable to the extent vested at any time prior to
the scheduled expiration date of the option. The Director Plan terminates on the
earlier  of June 16,  2009 or at such  time as all  shares of our  common  stock
currently or hereafter  reserved  for  issuance  shall have been issued,  unless
sooner terminated by the Board of Directors.

         In the event that our common stock shall be subdivided or combined into
a greater or smaller  number of shares or if we shall issue any shares of common
stock as a stock dividend on our outstanding  common stock, the number of shares
of common  stock  deliverable  upon the  exercise of options  granted  under the
Director Plan shall be appropriately increased or decreased proportionately, and
appropriate adjustments shall be made in the purchase price per share to reflect
such subdivision,  combination or stock dividend. In the event that we are to be
consolidated  with or  acquired  by another  entity in a merger,  sale of all or
substantially  all of our assets or  otherwise,  each option  granted  under the
Director Plan which is outstanding but unvested as of the effective date of such
event shall become fully exercisable.

         Our Board of Directors  may, at any time and from time to time,  modify
or amend the  Director  Plan in any respect  effective  at any date the Board of
Directors determines;  provided,  that without the approval of our stockholders,
the Board of  Directors  may not:  (i)  except as  provided  in Section 8 of the
Director  Plan,  increase the maximum number of shares of our common stock which

                                       25

may be issued on  exercise  of Options or the  payment  of  Compensation  Shares
granted  under the Director  Plan;  (ii) change the  provisions  of Section 6 or
Section 7 of the  Director  Plan;  or (iii)  change  the  categories  of persons
eligible to receive options or  Compensation  Shares under the Director Plan. No
modification or amendment of the Director Plan will,  without the consent of the
holder of an outstanding  Option or Compensation  Shares,  adversely  affect the
holder's rights under that Option or with respect to such Compensation Shares.

Previously Granted Options Under the Director Plan

         As of March 31, 2002,  we had granted  options to purchase an aggregate
of 271,666 shares of common stock (net of cancellations) under the Director Plan

167,940  options to purchase  shares were vested and 10,726  options to purchase
shares had been  exercised  under the Director  Plan.  The following  table sets

Background Regarding By-Laws

General

         The By-Laws  were last  amended by our Board of  Directors  on June 19,
2001.  The By-Laws  generally  provide that our  property,  business and affairs
shall be  managed  and  controlled  by our  Board  of  Directors.  The  Board of
Directors shall exercise all of the powers and duties conferred by law except as

                                       26



provided by the  Certificate  of  Incorporation  or the  By-Laws.  Copies of the
By-Laws may be obtained by our  stockholders  upon  request to the office of our
Corporate Secretary.

Federal Income Tax Treatment of the 1995 Plan and Director Plan

         The  following  is a summary of the United  States  federal  income tax
consequences  that generally will arise with respect to awards granted under the
1995 Plan and/or the  Director  Plan and with  respect to the sale of our common
stock acquired  under such plans.  This summary is based on the federal tax laws
in effect as of the date of this  Proxy  Statement.  Changes to these laws could
alter the tax consequences described below.

         The  options  issued  or to be  issued  under  the  1995  Plan  may  be
designated as either  incentive  stock  options  (ISOs) or  non-qualified  stock
options  (NQSOs),  and options under the Director Plan may only be designated as
NQSOs.

         In general,  a participant  will not recognize  taxable income upon the
grant or exercise of an ISO.  Instead,  a  participant  will  recognize  taxable
income  with  respect  to an ISO only  upon the sale of  common  stock  acquired
through the  exercise of the option,  or "ISO  Stock".  The  exercise of an ISO,
however, may subject the participant to the alternative minimum tax.

         Generally,  the  tax  consequences  of  selling  ISO  Stock  will  vary
depending on the date on which it is sold.  If the  participant  sells ISO Stock
more than two years from the date the option was  granted and more than one year
from the date the option was  exercised,  then the  participant  will  recognize
long-term capital gain in an amount equal to the excess of the sale price of the
ISO Stock over the exercise price.

         If the  participant  sells  ISO  Stock  prior to  satisfying  the above
waiting periods, then all or a portion of the gain recognized by the participant
will be ordinary  compensation  income and the remaining gain, if any, will be a
capital  gain.  This  capital  gain  will  be a  long-term  capital  gain if the
participant  has held the ISO Stock for more than one year  prior to the date of
sale.

         If a participant sells ISO Stock for less than the exercise price, then
the participant will recognize  capital loss in an amount equal to the excess of
the exercise price over the sale price of the ISO Stock.  This capital loss will
be a long-term  capital loss if the  participant has held the ISO Stock for more
than one year prior to the date of sale.

         NQSOs are  taxed  pursuant  to  Section  83 of the  Code.  If a NQSO is
granted  in  connection  with the  performance  of  services  and has a "readily
ascertainable  fair market value" at the time of the grant, the optionee will be
deemed to have  received  compensation  income in the year of grant in an amount
equal to the excess of the fair market  value of the option at the time of grant
over the amount,  if any, paid by the optionee for the option.  However,  a NQSO
generally has "readily  ascertainable fair market value" only when the option is
actively  traded  on an  established  market  and when  certain  stringent  Code
requirements are met.

         If the option does not have a readily  ascertainable  fair market value
at the time of the grant,  the option is not included as compensation  income at
that time. Rather, the optionee realizes ordinary  compensation income only when
the option is exercised and the optionee has become  substantially vested in the
shares  transferred.  The shares are considered to be substantially  vested when
they are either transferable or not subject to a substantial risk of forfeiture.
The amount of ordinary  compensation  income  realized is equal to the excess of
the fair market value of the shares at the time the shares become  substantially
vested over the sum of the exercise  price plus the amount,  if any, paid by the
optionee for the option.

         If a NQSO is exercised  through  payment of the  exercise  price by the
delivery of common  stock,  to the extent that the number of shares  received by
the optionee  exceeds the number of shares  surrendered,  ordinary  compensation
income  will be realized  by the  optionee at that time equal to the  difference
between the fair market value of such excess shares and the tax basis (generally
zero) of such excess shares.  We are generally  entitled to a tax deduction with
respect to any ordinary  compensation  income  recognized by a participant under
the 1995 Plan. Any such deduction will be subject to the  limitations of Section
162(m) of the Code.


                                       27


         Generally,  the  optionee's  basis in the shares  will be the  exercise
price plus the  optionee's  basis in the  option.  The  optionee's  basis in the
option is equal to the sum of the  compensation  income  realized at the time of
grant or exercise,  whichever is applicable, and the amount, if any, paid by the
optionee for the option. In the compensatory option context,  optionees normally
pay nothing for the grant of the option so the basis in the option will  usually
be the amount of ordinary  compensation  income realized at the time of grant or
exercise.  Thus, the  optionee's  basis in the shares will generally be equal to
the exercise price of the option plus the amount of ordinary compensation income
realized by the  optionee.  The capital gain or loss will be  short-term  if the
shares  are  disposed  of within one year  after the  option is  exercised,  and
long-term  if the shares are  disposed of more than one year after the option is
exercised.

         If a NQSO is taxed at the time of grant and  expires or lapses  without
being exercised,  it is treated in the same manner as the lapse of an investment
option.  The lapse is deemed to be a sale or  exchange  of the option on the day
the option  expires or lapses and the amount of income  realized by the optionee
is zero. The optionee  recognizes a capital loss in the amount of the optionee's
basis (ordinary  compensation  income realized at the time of the grant plus the
amount,  if any,  paid by the optionee for the option) in the option at the time
of the lapse.  This capital loss is short-term  or  long-term,  depending on the
optionee's holding period in the option.

         If a NQSO is not  taxed at the  time of grant  and  expires  or  lapses
without  being  exercised,   the  optionee  will  have  no  federal  income  tax
consequences unless the optionee paid for the option. In such case, the optionee
would  recognize a capital  loss in the amount of the price paid by the optionee
for the option.  This capital loss is short-term or long-term,  depending on the
optionees holding period in the option.

Reasons for and General Effect of Proposed Amendments to the 1995 Plan, the
Director Plan and By-Laws

         On January 18, 2002, we entered into a share  purchase  agreement  with
our principal  stockholder,  the State of Wisconsin  Investment  Board, or SWIB,
pursuant to which we issued and sold  2,970,665  shares of our common  stock for
aggregate proceeds of approximately $8.0 million.  Under the terms of such share
purchase agreement, we were required to ensure that our Director Plan, 1995 Plan
and By-Laws did not permit us to:

         (a) grant any stock option, including stock appreciation right, with an
exercise price that is less than 100% of the fair market value of the underlying
stock on the date of grant;

         (b) reduce the  exercise  price of any stock  option,  including  stock
appreciation  right,  outstanding  or to be  granted in the  future;  cancel and
re-grant options at a lower exercise price (including entering into any "6 month
and 1 day"  cancellation  and  re-grant  scheme),  whether or not the  cancelled
options  are put back into the  available  pool for  grant;  replace  underwater
options with  restricted  stock in an  exchange,  buy-back or other  scheme;  or
replace  any  options  with  new  options  having  a  lower  exercise  price  or
accelerated vesting schedule in an exchange, buy-back or other scheme; or

         (c) amend or repeal such Amendments or the requirement for such
Amendments.

         Previously,  on June 19, 2001, our Board of Directors  approved amended
versions of the 1995 Plan, the Director Plan and the By-Laws  incorporating most
of such restrictions pursuant to the terms of a share purchase agreement that we
had executed with SWIB. Such restrictions did not require stockholder  approval,
but did prohibit further  amendments to such  restrictions  without  stockholder
approval.  At that time, we issued and sold 1,820,000 shares of our common stock
to SWIB for aggregate proceeds of approximately $8.2 million.

         The  additional  amendments  to the 1995 Plan,  the  Director  Plan and
By-Laws required at this time are amendments which further restrict our ability,
without  the  approval of a majority  of our  stockholders,  to: (a) grant stock
appreciation  rights  with an  exercise  price that is less than the fair market
value of the  underlying  common  stock;  or (b)  effectively  amend or  replace
certain  outstanding  equity-based awards in a manner that would result in lower
exercise  prices,  accelerated  vesting  schedules or the issuance of restricted
stock (the "Amendments").  We are seeking stockholder approval of the Amendments
herein.


                                       28


         The incorporation of such Amendments into our 1995 Plan,  Director Plan
and By-Laws  could  further  impact our ability to  provide,  on certain  terms,
competitive   equity-based   compensation   to  our  employees,   directors  and
consultants.  Our Board of Directors will not have the  discretion,  without the
approval of a majority of our stockholders,  to grant stock appreciation  rights
having  an  exercise  price  that is less  than  the  fair  market  value of the
underlying   common  stock.  We  will  also  be  precluded,   without  requisite
stockholder  approval,  from modifying certain terms of existing and outstanding
options that we have already  granted.  Furthermore,  we will be prohibited from
reducing  the  exercise  price  of  any   outstanding   stock  option  or  stock
appreciation right or performing any action that has the same or similar effect,
whether or not such option or stock appreciation right was granted pursuant to a
plan or  otherwise.  These  restrictions  may limit our  ability to attract  and
retain management, directors, employees or consultants, or to provide motivating
equity  incentives  to such persons  because we will not be able to grant awards
having immediate  economic value to the recipient or modify  outstanding  awards
that do not, and may not ever have economic value.

         Our  success  depends  in large part upon our  ability  to attract  and
retain qualified scientific, technical,  administrative and management personnel
as well as the continued contributions of our existing personnel. Our failure to
continue  to attract  and retain  qualified  personnel  may limit our ability to
achieve our  business  objectives  and could make it  difficult  for us to raise
additional funds or to attract or engage strategic  partners.  From time to time
in the past,  we have  repriced  certain  outstanding  options to  maintain  the
economic  value and incentive  nature of such options.  At this time, we believe
that our current equity-based  compensation  programs,  as amended, will provide
our personnel with an  opportunity  to acquire a meaningful  equity stake in our
business,   while  continuing  to  align  their  interests  with  those  of  our
stockholders.

         Our  Board  of  Directors  has  approved  the  Amendments   subject  to
stockholder  approval.  Our By-Laws  govern and set forth certain of the powers,
rights,  duties and  obligations  of our Board of Directors  and  officers,  and
accordingly, by incorporating such Amendments into our By-Laws, we are providing
that our directors and officers  cannot adopt new equity  compensation  plans or
arrangements  that are  inconsistent  with the provisions of our By-Laws,  as so
amended, without the requisite approval of our stockholders.  If we determine at
a future date that these restrictions are no longer in the best interests of our
stockholders,  then we can seek stockholder  approval to change the restrictions
at that time.

         The  Board  of  Directors  recommends  a vote FOR the  approval  of the
Amendments to the 1995 Plan, the Director Plan and the By-Laws.

                   INFORMATION CONCERNING INDEPENDENT AUDITORS

         Arthur  Andersen LLP has served as our independent  public  accountants
since 1982.  Our Board of  Directors  has no reason to  question  the quality or
integrity of the audit and other assurance  services provided by Andersen during
this  time.  However,  during  the  past  several  months  our  Board  has  been
monitoring,  and will continue to monitor,  ongoing developments relating to the
investigation  of  Andersen  and  criminal  allegations  that have been  brought
against the firm. In  consideration of these  developments,  our Board has asked
management to hold discussions with other auditing firms, and these  discussions
are ongoing as of the date hereof.  Following these  discussions,  our Board may
engage another firm for auditing  services  beginning in 2002. We have requested
that  a  representative   from  Andersen  attend  our  2002  Annual  Meeting  of
Stockholders.  Such representative will have an opportunity to make a statement,
if he or she desires, and will be available to respond to appropriate  questions
from stockholders.

                             STOCKHOLDERS' PROPOSALS

         Stockholders who intend to have a proposal  considered for inclusion in
our proxy materials for  presentation at our 2003 Annual Meeting of Stockholders
pursuant to Rule 14a-8 under the Exchange  Act must submit their  proposal to us
at our offices at 600 College Road East, CN 5308, Princeton,  New Jersey, 08540,
attention H. Joseph Reiser not later than January 9, 2003.

         Stockholders  who intend to present a proposal at such meeting  without
inclusion of such proposal in our proxy  materials  pursuant to Rule 14a-8 under
the Exchange Act are required to provide  advanced notice of such proposal to us
at the aforementioned address not later than March 25, 2003.

                                       29


         If we do not  receive  notice of a  stockholder  proposal  within  this
timeframe,  our  management  will use its  discretionary  authority  to vote the
shares they represent,  as our Board of Directors may recommend.  We reserve the
right to  reject,  rule out of order,  or take  other  appropriate  action  with
respect  to any  proposal  that does not  comply  with  these  other  applicable
requirements.

                    HOUSEHOLDING OF ANNUAL MEETING MATERIALS

         The SEC has also recently adopted a "householding" rule which we intend
to  implement  for future  stockholder  communications.  This rule permits us to
deliver a single proxy or information statement to a household,  even though two
or more  stockholders  live  under the same  roof or a  stockholder  has  shares
registered in multiple  accounts.  This rule enables us to reduce the expense of
printing and mailing  associated with proxy statements and reduces the amount of
duplicative  information you may currently receive.  If this rule applies to you
and  you  wish  to  continue   receiving   separate  proxy   materials   without
participating in the "householding" rule, please check the designated box on the
enclosed  proxy card.  If we do not hear from you within 60 days, we will assume
that we have your implied  consent to deliver one set of proxy  materials  under
the new rule.  This implied  consent  will  continue for as long as you remain a
stockholder of the company,  unless you inform us in writing  otherwise.  If you
revoke your consent, we will begin sending separate copies within 30 days of the
receipt of your revocation.

         Some  banks,  brokers  and other  nominee  record  holders  are already
"householding"  proxy  statements and annual  reports.  This means that only one
copy of our proxy  statement  or annual  report  may have been sent to  multiple
stockholders  in your  household.  We will  promptly  deliver a separate copy of
either  document  to you if you  write  us at 600  College  Road  East  CN-5308,
Princeton,  New  Jersey  08540,  or call us at  (609)  750-8200.  If you want to
receive  separate copies of the annual report and proxy statement in the future,
or if you are receiving  multiple copies and would like to receive only one copy
for your  household,  you should  contact your bank,  broker,  or other  nominee
record holder, or you may contact us at the above address and phone number.

                                  OTHER MATTERS

         Our Board of Directors  is not aware of any matter to be presented  for
action at the Annual Meeting other than the matters  referred to above, and does
not intend to bring any other matters  before the Annual  Meeting.  However,  if
other matters should come before the Annual  Meeting,  we intend that holders of
the proxies will vote thereon in their discretion.

                                     GENERAL

         The  accompanying  proxy is  solicited by and on behalf of our Board of
Directors,  whose notice of meeting is attached to this Proxy Statement, and the
entire cost of such solicitation will be borne by us.

         In  addition  to the use of the  mails,  proxies  may be  solicited  by
personal interview,  telephone and telegram by our directors, officers and other
employees who will not be specially compensated for these services. We will also
request  that  brokers,  nominees,  custodians  and  other  fiduciaries  forward
soliciting  materials to the beneficial  owners of shares held of record by such
brokers,  nominees,  custodians  and other  fiduciaries.  We will reimburse such
persons for their reasonable expenses in connection therewith.

         Certain  information  contained in this Proxy Statement relating to the
occupations  and security  holdings of our  directors and officers is based upon
information received from the individual directors and officers.

         WE WILL FURNISH,  WITHOUT CHARGE, A COPY OF OUR REPORT ON FORM 10-K FOR
THE YEAR ENDED DECEMBER 31, 2001,  INCLUDING  CONSOLIDATED  FINANCIAL STATEMENTS
BUT NOT INCLUDING  EXHIBITS,  TO EACH OF OUR STOCKHOLDERS OF RECORD ON APRIL 22,
2002, AND TO EACH BENEFICIAL  STOCKHOLDER ON THAT DATE UPON WRITTEN REQUEST MADE

REASONABLE FEE WILL BE CHARGED FOR COPIES OF REQUESTED EXHIBITS.

subject to  adjustment  as provided in Section 8. If any Option or  Compensation
Share expires or is cancelled,  surrendered or forfeited without being exercised

is not exercised, or Options or Compensation Shares are canceled, surrendered or
forfeited, will once again become shares as to which new Options or Compensation
Shares may be granted.  The Common  Stock  which is issued upon the  exercise of
Options or issued as  Compensation  Shares may be authorized but unissued shares
or shares which have been issued and  reacquired  by the  Company.

          Initial  Option  shall  become  exercisable  in  one-third  increments
          annually on the first,  second, and third anniversaries of the Date of

office:

     (i)  a notice of exercise of the Option,  which  states the extent to which
          the option is being exercised; and

     (ii) payment  in full in cash,  which may be  satisfied  by a check,  in an
          amount equal to the  Exercise  Price of the option times the number of
          shares as to which it is being exercised.

                                      A-5

owed such  Compensation  Shares,  certificates  registered in that person's name
representing  the number of shares of Common  Stock which were  purchased by the
exercise of the option or grant of  Compensation  Shares in payment for services
rendered.  Each certificate may bear a legend to indicate,  if applicable,  that
the Common Stock  represented  by the  certificate  was issued in a  transaction
which was not registered  under the Securities Act of 1933, as amended,  and may
only be sold or transferred in a transaction  which is registered under that Act
or is exempt from the registration requirements of that Act.

    (e)  Nontransferability

     (i)  Options.  During the lifetime of a person to whom an option is issued,
          the Option may be exercised only by that person or his or her guardian
          or legal  representative.  An Option may not be  assigned,  pledged or
          hypothecated  in any way, will not be subject to  execution,  and will
          not be transferable  otherwise than by will or the laws of descent and
          distribution.  The Company will not  recognize  any attempt to assign,
          transfer,  pledge,  hypothecate  or  otherwise  dispose  of an  option
          contrary to the provisions of this Plan, or any levy of any attachment
          or similar process upon any Option, and, except as expressly stated in
          this Plan,  the Company will not be required  to, and will not,  issue
          Common  Stock on  exercise  of an option to anyone  who claims to have
          acquired that option from the person to whom it was granted.

     (ii) Compensation  Shares.  For one  year  after  the date of  issuance  of
          Compensation Shares to any Eligible Director, such Compensation Shares
          shall not be transferable by such Eligible  Director.  During this one
          year  period,  Compensation  Shares  may not be  assigned,  pledged or
          hypothecated in any way, and will not be  transferable  otherwise than
          by will or the laws of descent and distribution.  The Company will not
          recognize  any attempt to assign,  transfer,  pledge,  hypothecate  or
          otherwise dispose of Compensation Shares contrary to the provisions of
          this Plan, or any levy of any  attachment or similar  process upon any
          Compensation Shares, and, except as expressly stated in this Plan, the
          Company  will not be  required  to, and will not,  remove any  related
          restrictive  legend from the  Compensation  Shares until such one year
          period has expired.  The Compensation  Shares shall bear a restrictive
          legend  evidencing  such  lock-up  (the  "Lock-up  Legend").  Upon the
          expiration of such one year lock-up period, Compensation Share s shall
          become fully  transferable by the holder,  subject to the terms of the
          Securities  Act of 1933,  as amended and state  securities  laws.  The
          Company shall take reasonable  steps to remove the Lock-up Legend from
          the Compensation  Shares within a reasonable time after the expiration
          of  such   period   upon  the   request  of  an   Eligible   Director.
          Notwithstanding such lock-up provision, upon the occurrence of a Major
          Event,  all of the  Compensation  Shares issued  hereunder to Eligible
          Directors  shall be  treated in a like  manner as are the  outstanding
          shares of the Company's Common Stock upon the occurrence of such Major
          Event.

                                      A-6

     (f) Termination of Service of Director Holding an Option Other Than Because
of Death or Disability.  Subject to the provisions of Sections 7(b) and 7(h), if
there is a  Termination  of  Service  of a  director  to whom an Option has been
granted,  other  than by  reason  of the  director's  death  or  disability,  or
retirement,  each Option held by the director may be exercised until the earlier
of (x) the end of the  three-month  period  immediately  following  the  date of
Termination of service, or (y) the expiration of the term of the option.

     (g) Death or Disability of Director Holding an Option.  Notwithstanding the
provisions of Section  7(b), if there is a Termination  of Service of a director
to whom an  option  has  been  granted  by  reason  of the  director's  death or
disability,  or a former director dies within three months following the date of
his or her Termination of Service,  each option held by the Director on the date
of the  Director's  Termination  of Service may be exercised  in full (i.e.,  in
respect of up to 100% of the Option shares, regardless of the time elapsed since
the Date of  Grant)  until the  earlier  of (x) the end of the  one-year  period
immediately  following the date of  Termination of service or (y) the expiration
of the term of the option. In the event of an Eligible  Director's death, all of
such person's  outstanding Options will transfer to the maximum extent permitted
by law to such person's designated Beneficiary. Each Eligible Director may name,
from  time to  time,  any  beneficiary  or  beneficiaries  (which  may be  named
contingent ly or  successively)  as his or her  Beneficiary for purposes of this
Plan. Each  designation  shall be on a form  prescribed by the Company,  will be
effective  only when delivered to the Company and when effective will revoke all
prior designations by the Eligible  Director.  If an Eligible Director dies with
no such  beneficiary  designation  in  effect,  such  person's  Options  will be
transferable  by will  or  pursuant  to the  laws of  descent  and  distribution
applicable to such person.

     (h)  Retirement or  Resignation.  If there is a Termination of Service of a
Director by reason of the Director's retirement or resignation at any time after
the  Director  has  reached age 55 with a minimum of three  years'  service as a
non-employee  director,  each  Option  held by the  Director  on the date of the
Director's  Termination of Service may be exercised in full (i.e., in respect of
up to 100% of the Option  Shares,  regardless of the time elapsed since the Date
of Grant)  until the earlier of (x) the end of the five year period  immediately
following the date of  Termination  of Service or (y) the expiration of the term
of the option.

8.   Recapitalization, reorganizations, stock splits and the like.

     (a) The existence of outstanding  Options or Compensation  Shares shall not
affect in any way the right or power of the Company or its  stockholders to make
or authorize any or all adjustments, recapitalizations, reorganizations or other
changes in the Company's  capital  structure or its  business,  or any merger or
consolidation of the Company,  or any issue of bonds,  debentures,  preferred or
prior  preference  stock ahead of or  affecting  the Common  Stock or the rights
thereof,  or the  dissolution  or  liquidation  of the  Company,  or any sale or
transfer of all or any part of its assets or business or any other corporate act
or  proceeding,   whether  of  a  similar  character  or  otherwise.  Except  as
hereinafter  expressly provided,  the issue by the Company of shares of stock of
any class, or securities convertible into shares of stock of any class, for cash
or  property,  or for labor or  services  either  upon  direct  sale or upon the


                                      A-7


exercise of rights or warrants to subscribe therefor, or on conversion of shares
or obligations o f the Company convertible into such shares or other securities,
shall not affect, and no adjustment by reason thereof shall be made with respect
to,  the  number,  class or price of shares  of Common  Stock  then  subject  to
outstanding options.

     (b) If as a result of any (i)  reorganization or liquidation of the Company
or (ii)  reclassification  of the Company's capital stock,  stock splits,  stock
splits  in  the  form  of   dividends,   reverse   stock   splits,   or  similar
recapitalizations  of the  Company,  or (iii)  consolidation  or  merger  of the
Company with or into another  corporation,  or sale of all or substantially  all
the assets of the Company (a  reorganization  or  liquidation  of the Company or
reclassification  of the Company's capital stock, or a merger,  consolidation or
sale of the type described in this subsection  being a "Corporate  Transaction")
while an Option is outstanding,  the holders of the Common Stock become entitled
to receive with respect to their Common Stock,  securities or assets other than,
or in addition to, their Common  Stock,  upon exercise of that Option the holder
will receive what the holder  would have owned if the holder had  exercised  the
Option immediately  before the first Corporate  Transaction which occurred while
the option was outstan  ding and had not  disposed of anything  the holder would
have  received as a result of that and all  subsequent  Corporate  Transactions.
Compensation Shares shall be adjusted in the same manner as the Company's Common
Stock in all events.

9.   Rights of Option  Holder.

     The holder of an Option will not have any rights as a stockholder by reason
of holding that Option. Upon exercise of an Option, the holder will be deemed to
acquire the rights of a stockholder when, but not before, the issuance of Common
Stock as a result  of the  exercise  is  recorded  in the stock  records  of the
Company.

10.  Laws and Regulations.

     The obligation of the Company to sell and deliver shares of Common Stock on
exercise of options or upon the issuance of Compensation  Shares will be subject
to the condition  that legal counsel for the Company be satisfied  that the sale
and delivery will not violate the  Securities  Act of 1933,  as amended,  or any
other applicable laws, rules or regulations.

11.  Reservation of Shares.

     The Company  will at all times keep  reserved  for  issuance on exercise of
options a number of authorized but unissued or reacquired shares of Common Stock
equal to the  maximum  number of shares the  Company may be required to issue on
exercise of  outstanding  options  (assuming  no  subsequent  adjustments  under
Section 8).

12.  Amendment of the Plan.

     The  Board of  Directors  may at any time and from  time to time  modify or
amend  this Plan in any  respect  effective  at any date the Board of  Directors
determines;  provided,  that  without the  approval of the  stockholders  of the
Company  the Board of  Directors  may not,  (i) except as provided in Section 8,

                                      A-8

increase  the  maximum  number of shares of Common  Stock which may be issued on
exercise of Options or the payment of  Compensation  Shares  granted  under this
Plan;  (ii) change the  provisions  of Section 6 or Section 7; (iii)  change the
categories of persons  eligible to receive options or Compensation  Shares under
this Plan; or (iv)  otherwise  materially  increase  (within the meaning of Rule
16b-3  of  the  Exchange  Act)  the  benefits   accruing  under  this  Plan.  No
modification  or amendment of this Plan will,  without the consent of the holder
of an outstanding Option or Compensation  Shares,  adversely affect the holder's
rights  under  that  Option  or  with  respect  to  such  Compensation   Shares.
Notwithstanding approval by shareholde rs, the Board may amend this Plan without
further shareholder approval to add provisions required or enabled by changes to
Rule 16b-3.

13.  Termination of the Plan.

     This Plan will terminate on June 16, 2009,  unless sooner  terminated.  The
Board of Directors  may suspend or terminate  this Plan at any time or from time
to time, but no such action may adversely  affect the rights of a person holding
an outstanding  Option or Compensation  Share. The applicable terms of the Plan,
and any terms and  conditions as applicable  to Options or  Compensation  Shares
granted  prior to such  date,  shall  survive  the  termination  of the Plan and
continue to apply to such Options or Compensation Shares.

     (b) No member of the  Committee  shall be liable for any act or omission of
the Committee or any other member of the  Committee,  or for any act or omission
on his own part, in connection with the  administration  of this Plan, unless it
resulted from the member's own willful misconduct.


4.   Persons Eligible to Receive Options.

     (a) Options may be granted  under this Plan only to persons who at the Date
of Grant  either (i) are  officers,  Employees  or Eligible  Consultants  of the

                                      B-3

Company  or any of its  Subsidiaries  or (ii) have  agreed  to become  officers,
Employees  or Eligible  Consultants  of the Company or any of its  Subsidiaries,
and, in either  case,  are  determined  by the  Committee  to be of  substantial
importance to the Company or any of its Subsidiaries.

     (b)  Options  granted to persons  who are not yet  officers,  Employees  or
Eligible  Consultants  at the  Date of  Grant  may not be  exercised  until  the
optionee  has become an  officer,  Employee or  Eligible  Consultant,  and shall
expire if the  optionee  fails to commence  service as an  officer,  Employee or
Eligible Consultant within six months (or such other period as the Committee may
determine) after the Date of Grant.

     (c)  Incentive  Stock  Options  may be  granted  only  to  persons  who are
Employees  at the Date of  Grant,  and only on such  terms  as are  provided  in
paragraphs 6, 7 and 8 hereof.

     (d) No Employee or Eligible Consultant to whom Options may be granted under
this Plan may be granted Options to purchase more than 200,000 shares in any one
calendar year.

5.   Stock Subject to the Plan.

     (a)  Subject to any  adjustment  as provided  in  paragraph  9, the maximum
number of shares of Common Stock as to which  Options may be granted  under this
Plan is 4,502,635  shares reduced by the number of outstanding  options  granted
under the Cytogen  Corporation 1989 Employee Stock Option Plan (the "1989 Plan")
that are exercised  after the effective date of this Plan. If any Option expires
or is cancelled or  surrendered  without being  exercised in full, the number of
shares as to which the Option is not exercised  will once again become shares as
to which  new  Options  may be  granted.  The  Common  Stock  which is issued on
exercise of Options may be authorized  but unissued  shares or shares which have
been issued and reacquired by the Company.

     (b) For  administrative  purposes  only, the Committee  shall  establish an
account  indicating the number of shares of Common Stock as to which Options may
then be granted under this Plan (the "Current  Account"),  and the Committee may
issue  Options  only with respect to the shares of Common  Stock  available  for
grant as set forth in the Current Account. The Current Account shall contain the
number of shares available for grant calculated as follows: (a) 4,502,635, minus
(b) the number of shares of Common Stock  subject to options  granted  under the
1989 Plan that are exercised  after the effective  date of this Plan,  minus (c)
the number of shares of Common  Stock  subject to  outstanding  options  granted
under the 1989 Plan and this Plan, plus (d) the number of shares of Common Stock
subject to outstanding options granted under the 1989 Plan and/or this Plan that
expire, are cancelled or surrendered without being exercised in full.

6.   Grants of Options.

     (a) Subject to paragraph 4(d), the Committee will have complete  discretion
to  determine  when,  and to which  officers  or  other  Employees  or  Eligible
Consultants,  Options are to be granted, the number of shares of Common Stock to
which Options granted to each officer or other Employee or Eligible  Consultant,
will relate,  whether and to what extent Options  granted to an officer or other

                                      B-4

Employee  or  Eligible   Consultant,   will  be  Incentive   Stock   Options  or
Non-Qualified  Options and, subject to the provisions of paragraphs 7 and 8, the
Exercise Price and the term of each Option. The Committee may, in its discretion
at the time of granting the Option,  provide that the Exercise Price may be paid
in cash,  by the surrender of Common Stock,  by an  interest-bearing  promissory
note, or by other means; subject, however, to any requirements of applicable law
which may limit the type or amount of such non-cash consideration. If payment by
promissory note is permitted:  (i) the optionee shall be required to make a cash
payment upon exercise of the Option of not less than 20% of the Exercise  Price;
(ii) the note shall provide for full recourse  against the maker;  and (iii) the
note shall be payable in full prior to its stated  maturity upon the  optionee's
Termination of Service for any reason other than death or Total Disability.

     (b) Any Options which are not  designated  as Incentive  Stock Options when
they are granted will be Non-Qualified Options.

     (c)  Promptly  after the Date of Grant of each  Option,  the Company  shall
cause an Option  Agreement  to be executed  and  delivered  to the holder of the
Option.  The Option  Agreement shall clearly state whether the Option granted is
or is not an Incentive Stock Option.  Separate Option  Agreements  shall be used
for Incentive Stock Options and Non-Qualified Stock Options.

     (d) Except as otherwise  determined  by the  Committee,  and subject to the
requirements  of  applicable  law,  the entire  Exercise  Price  received by the
Company upon the exercise of an option shall  constitute  stated  capital to the
extent of the  aggregate  par value of the Common Stock issued upon  exercise of
the Option.

     (e) Any  Option  granted  under  this  Plan  prior  to the date the Plan is
approved by the Company's stockholders shall not be exercisable unless and until
the Plan is so approved.

7.   Option Provisions.

     (a) Exercise Price. No  consideration  shall be payable by any optionee for
the grant of an Option.  Subject to the  provisions  of  paragraph  7(a)(i)  and
paragraph  8, the  Exercise  Price of each Option will be as  determined  by the
Committee.

          (i) The  Committee  shall not grant any Option with an exercise  price
     that is less than 100% of the Fair Market Value of the underlying  stock on
     the date of grant or reduce the exercise  price of any Option granted under
     the Plan.


     (b) Term.  The term of each Option will be as determined by the  Committee,
but in no event  will the term of an Option be  longer  than ten years  from the
Date of Grant, or five years in the case of an Incentive Stock Option granted to
a Ten Percent Shareholder.  Options may not be exercised before six months after
the Date of Grant.  Options will cease to be exercisable prior to the expiration
of their term under certain  circumstances  as provided in paragraphs 7(f), (g),
and (h).  Subject  to the  foregoing,  and to any  vesting  or other  conditions
imposed at the time it is  granted,  an Option may be  exercised  in whole or in
part at any time, or from time to time, during its term.

                                      B-5

     (c) Manner of Exercise.  To exercise an Option,  the person  exercising the
Option must deliver to the Company, at its principal office:

          (i) a notice of exercise,  which states the extent to which the Option
     is being exercised;

          (ii) a certified or bank cashier's check in an amount, or Common Stock
     with a Fair Market Value,  equal to the Exercise  Price of the Option times
     the number of shares as to which it is being exercised, or consideration in
     such other form as may be permitted  under the terms on which the Option is
     granted; and

          (iii) a certified  or bank  cashier's  check equal to any  withholding
     taxes the Company is required to pay because of the exercise of the Option.

     The  Committee  may permit an  Employee,  as an  alternative  to making the
     payment  described in clause (iii),  to authorize the Company to withhold a
     sum equal to the withholding  taxes the Company is required to pay from the
     Employee's  salary  and bonus  payments  over a period of not more than six
     months (or such  longer  period as the Company  may  approve).  The date on
     which the Company  receives all the items specified in this subsection will
     be the date on which the Option is exercised to the extent described in the
     notice of election.

     (d) Delivery of Stock  Certificates.  As promptly as  practicable  after an
Option is  exercised,  the Company will deliver to the person who  exercises the
Option certificates,  registered in that person's name,  representing the number
of shares of Common  Stock which were  purchased  by the exercise of the Option.
Each  certificate  may bear a legend to indicate,  if  applicable,  that (i) the
Common Stock  represented by the certificate  was issued in a transaction  which
was not registered under the Securities Act of 1933, as amended, and may only be
sold or  transferred in a transaction  which is registered  under that Act or is
exempt from the registration requirements of that Act, and (ii) the Common Stock
represented by the certificate is subject to the obligation of the holder to pay
any unpaid balance of the Exercise Price (whether  pursuant to a promissory note
or  otherwise),  and/or  that the  Common  Stock is  pledged  to secure  such an
obligation.

     (e)  Nontransferability  of Options.  During the  lifetime of the person to
whom an Option is issued, the Option may be exercised only by that person or his
or her guardian or legal representative.  An Option may not be assigned, pledged
or  hypothecated  in any way, will not be subject to execution,  and will not be
transferable otherwise than by will or the laws of descent and distribution. The
Company will not recognize any attempt to assign, transfer,  pledge, hypothecate
or otherwise  dispose of an Option  contrary to the  provisions of this Plan, or
any levy of any attachment or similar  process upon any Option,  and,  except as
expressly  stated in this Plan,  the Company  will not be required  to, and will
not,  issue  Common  Stock on exercise of an Option to anyone who claims to have
acquired that Option from the person to whom it was granted.


                                      B-6

     (f)  Termination of Service of Holder of Option Other Than Because of Total
Disability or Death. If there is a Termination of Service of a person to whom an
Option has been  granted,  other than by reason of the  person's  death or Total
Disability,  each  Option  held by the person  may be  exercised  (if  otherwise
exercisable)  until  the  earlier  of (i)  the  end of  the  three-month  period
immediately  following  the  date  of  the  Termination  of  Service,  (ii)  the
expiration  of the term  specified in the Option,  or (iii) such earlier time as
may be determined by the Committee at the time of granting the Option.

     (g) Total  Disability  of Holder of Option.  If there is a  Termination  of
Service of a person to whom an Option  has been  granted by reason of his or her
Total Disability,  each Option held by the person may be exercised (if otherwise
exercisable) until the earlier of (i) the end of the one-year period immediately
following the date of the  Termination  of Service,  (ii) the  expiration of the
term specified in the Option, or (iii) such earlier time as may be determined by
the Committee at the time of granting the Option.

     (h) Death of Holder of Option.  If there is a  Termination  of Service of a
person to whom an Option has been  granted  by reason of his or her death,  or a
former officer or Employee or Eligible Consultant dies following the date of his
or her  Termination  of  Service  but at a time  when an Option  still  would be
exercisable by that person but for the death of the person,  each Option held by
the  person at the time of his or her death may be  exercised  by the  person or
persons  to  whom  the  Option  passed  by will or by the  laws of  descent  and
distribution  (but by no other  persons) until the earlier of (i) the end of the
one-year period immediately following the date of death (or such other period as
may be determined by the Committee at the time of granting the Option), (ii) the
expiration  of the term  specified  in the Option,  or (iii) if the death occurs
after the  Termination  of  Service,  the end of the  period in which the Option
could be exercised under paragraph 7(f) or (g).

     8. Special  Provisions  Relating to Incentive  Stock Options.  No Incentive
Stock  Option may be granted  after March 27,  2005.  The  Exercise  Price of an
Incentive  Stock  Option will be not less than 100% of the Fair Market  Value of
the Common Stock on the Date of Grant of the Option.  An Incentive  Stock Option
may not be granted to a person who, at the time the Option is granted,  is a Ten
Percent  Shareholder,  unless (i) the  Exercise  Price of the Option is at least
110% of the Fair Market  Value of the Common Stock on the Date of Grant and (ii)
the Option by its terms is not  exercisable  after the  expiration of five years
from the Date of Grant.  To the extent  that the  aggregate  Fair  Market  Value
(determined  at the time an  Incentive  Stock  Option is  granted) of the Common
Stock with respect to which Incentive Stock Options are first  exercisable by an
Employee during any calendar year (under this Plan and any other incentive stock
option plans of the Company) exceeds $100,000,  such Options shall be treated as
Non-Qualified  Options.


                                      B-7

9.   Recapitalization.

     (a) The  existence of  outstanding  Options shall not affect in any way the
right or power of the Company or its  stockholders  to make or authorize  any or
all  adjustments,  recapitalizations,  reorganizations  or other  changes in the
Company's capital  structure or its business,  or any merger or consolidation of
the Company,  or any issue of bonds,  debentures,  preferred or prior preference
stock  ahead of or  affecting  the Common  Stock or the rights  thereof,  or the
dissolution or liquidation of the Company, or any sale or transfer of all or any
part of its assets or business or any other corporate act or proceeding, whether
of a similar character or otherwise.  Unless otherwise  determined by the Board,
the  issue  by the  Company  of  shares  of stock of any  class,  or  securities
convertible  into  shares of stock of any class,  for cash or  property,  or for
labor or services  either  upon  direct  sale or upon the  exercise of rights or
warrants to subscribe therefor, or on conversion of shares or obligations of the
Company convertible into such shares or other securities,  shall not affect, and
no adjustment by reason thereof shall be made with respect to, the number, class
or price of shares of Common Stock then subject to outstanding Options.

     (b) If as a result of any (i)  reorganization or liquidation of the Company
or (ii)  reclassification of the Company's capital stock, or (iii) consolidation
or merger of the Company  with or into  another  corporation,  or sale of all or
substantially  all the assets of the Company (a reorganization or liquidation of
the Company or  reclassification  of the Company's  capital stock,  or a merger,
consolidation  or  sale  of the  type  described  in  this  subsection  being  a
"Corporate  Transaction")  while an Option is  outstanding,  the  holders of the
Common  Stock become  entitled to receive  with  respect to their Common  Stock,
securities  or assets other than,  or in addition to, their Common  Stock,  upon
exercise of that Option the holder will receive what the holder would have owned
if the  holder  had  exercised  the  Option  immediately  before  the  Corporate
Transaction which occurred while the Option was outstanding and had not disposed
of  anything  the  holder  would  have  received  as a  result  of that  and all
subsequent Corporate Transactions.

10. Rights of Option Holder.

     (a) The holder of an Option  will not have any rights as a  stockholder  by
reason of holding that Option.  Upon  exercise of an Option,  the holder will be
deemed to acquire the rights of a stockholder when, but not before, the issuance
of Common Stock as a result of the exercise is recorded in the stock  records of
the Company.

     (b)  Nothing in this Plan or in the grant of an Option will confer upon any
Employee  the  right  to  continue  in the  employment  of the  Company  or will
interfere with or restrict in any way the rights of the Company to discharge any
Employee at any time for any reason whatsoever,  with or without cause, nor will
it impose any obligation on the Employee to remain in the employ of the Company.


     11. Laws and Regulations. The obligation of the Company to sell and deliver
shares of Common Stock on exercise of Options  will be subject to the  condition
that legal counsel for the Company be satisfied  that the sale and delivery will
not violate the  Securities  Act of 1933,  as amended,  or any other  applicable
laws,  rules or regulations.

                                      B-8

12.  Withholding of Taxes.

     (a) In  addition  to the  requirement  in  paragraph  7(c) that in order to
exercise  an Option a person  must make a payment to the  Company  or  authorize
withholding in order to enable the Company to pay any withholding taxes due as a
result of the  exercise,  if a person who  exercised an  Incentive  Stock Option
disposes of shares of Common Stock acquired  through  exercise of that Incentive
Stock  Option  either  (i)  within  two  years  after  the  Date of Grant of the
Incentive  Stock Option or (ii) within one year after the issuance of the shares
on exercise of the Incentive  Stock  Option,  the person will notify the Company
promptly of the  occurrence of the event and, if the event was a disposition  of
Common  Stock  acquired on exercise of an  Incentive  Stock  Option,  the amount
realized upon the disposition.

     (b) If,  whether  because of a  disposition  of Common  Stock  acquired  on
exercise of an Incentive Stock Option, or otherwise,  the Company is required to
pay withholding  taxes to any Federal,  state or other taxing  authority and the
Employee  fails to  provide  the  Company  with the funds with which to pay that
withholding tax, the Company may withhold up to 50% of each payment of salary or
bonus to the  Employee  (which  will be in  addition  to any other  required  or
permitted  withholding),  until the Company has been  reimbursed  for the entire
withholding tax it was required to pay.

     (c) The  obligations  contained  in  this  paragraph  12  shall  bind  each
optionee,  and each optionee, by accepting and/or exercising an Option, shall be
deemed to agree to observe and comply with them.

     13.  Reservation of Shares. The Company will at all times keep reserved for
issuance  on  exercise  of  Options  a number  of  authorized  but  unissued  or
reacquired  shares of Common  Stock  equal to the  maximum  number of shares the
Company may be required to issue on exercise of outstanding Options (assuming no
subsequent adjustments under paragraph 9).

     14.  Amendment of the Plan. The Board of Directors may at any time and from
time to time modify or amend this Plan in any respect  effective at any date the
Board of  Directors  determines;  provided,  that  without  the  approval of the
stockholders  of the  Company  the Board of  Directors  may not,  (i)  except as
provided in paragraph 9,  increase the maximum  number of shares of Common Stock
which may be issued on exercise of Options  granted under this Plan; (ii) change
the  categories  of persons  eligible to receive  Options;  (iii)  increase  the
per-optionee  limit  specified  in  paragraph  4(d),  (iv) take any other action
requiring the approval of the  stockholders  of the Company in order to maintain
the exemption available under Rule 16b-3 (or any similar rule) of the Securities
and Exchange  Commission,  or (v) modify the provisions of paragraph 7(a)(i). No
modification  or amendment of this Plan will,  without the consent of the holder
of an  outstanding  Option,  adversely  affect the  holder's  rights  under that
Option.

                                      B-9

     15. Interpretation The Committee shall have the power to interpret the Plan
and to make and amend rules for putting it into effect and  administering it. It
is  intended  that the  Incentive  Stock  Options  granted  under the Plan shall
constitute  incentive  stock  options  within the  meaning of section 422 of the
Code,  that the  Non-Qualified  Options  shall  constitute  property  subject to
federal income tax pursuant to the provisions of section 83 of the Code and that
the Plan shall  qualify  for the  exemption  available  under Rule 16b-3 (or any
similar rule) of the  Securities  and Exchange  Commission.  It is also intended
that all  compensation  income  recognized  by  optionees  as the  result of the
exercise of Options or the  disposition  of Common Stock acquired on exercise of
Options shall be considered performance-based  compensation excludable from such
optionee's  "applicable employee  remuneration" pursuant to section 162(m)(4)(C)
of the Code. The provisions of the Plan shall be interpreted and applied insofar
as possible to carry out such intent.

     16.  Termination of the Plan.  This Plan shall  terminate on March 27, 2005
unless sooner  terminated.  The Board of Directors may suspend or terminate this
Plan at any time or from time to time,  but no such action may adversely  affect
the rights of a person holding an outstanding Option.

     SECTION 1. NOTICE.  Whenever any written  notice is required to be given by
law, the Certificate of Incorporation or these By-Laws,  such notice, if mailed,

law, the Certificate of Incorporation or these By-laws, a written waiver thereof
signed by the person entitled to notice, whether before or after the time stated
therein,  shall be deemed  equivalent  to  notice.  Attendance  of a person at a
meeting  shall  constitute a waiver of notice of such  meeting,  except when the
person attends a meeting for the express purpose of objecting,  at the beginning
of the meeting,  to the  transaction of any business  because the meeting is not
lawfully  called or convened.  Neither the business to be transacted at, nor the
purpose  of,  any  meeting  of the  stockholders,  directors,  or  members  of a
committee of the Board need be specified in any written waiver of notice.

regulating an impending election of directors is adopted, amended or repealed by
the  Board,  there  shall be set  forth in the  notice  of the next  meeting  of
shareholders for the election of directors the By-Law(s) so adopted, amended, or
repealed, together with a precise statement of the changes made. By-Laws adopted
by  Board  of   Directors   may  be  amended  or   repealed   by   stockholders.
Notwithstanding  the  foregoing to the  contrary,  the  provisions  of Article X
hereof may not be further amended or repealed  without the  affirmative  vote of
the  holders of a  majority  of the  shares of common  stock of the  Corporation
present and entitled to vote at a duly convened  meeting of the  stockholders of

                                 INDEMNIFICATION

     SECTION 1. A director of the Corporation  shall not be personally liable to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director,  except for liability  (i) for any breach of the  director's
duty  of  loyalty to  the Corporation or  its stockholders, (ii) for  acts  or

                                      C-9

omissions not in good faith or which involve intentional misconduct or a knowing
violation of law,  (iii) under Section 174 of the Delaware  General  Corporation
Law, or (iv) for any  transaction  from which the  director  derived an improper
personal benefit.

     SECTION 2. Each  person who has or is made a party or is  threatened  to be
made a party to or is involved in any action, suit or proceeding, whether civil,
criminal,  administrative  or  investigative  (hereinafter a  "proceeding"),  by
reason  of the fact  that he or she,  or a person of whom he or she is the legal
representative,  is or  was a  director,  officer,  employee  or  agent  of  the
Corporation  or is or  was  serving  at the  request  of  the  Corporation  as a
director, officer, employee or agent of another corporation or of a partnership,
joint  venture,  trust or other  enterprise,  including  service with respect to
employee  benefit plans,  whether the basis of such proceeding is alleged action
or inaction in an official capacity as a director, officer, employee or agent or
in any other capacity while serving as a director,  officer,  employee or agent,
shall be indemnified  and held harmless by the Corporation to the fullest extent
permitted by the  Delaware  General  Corporation  Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the extent
that such amendment  permits the Corporation to provide broader  indemnification
rights  than  said  law  permitted  the  Corporation  to  provide  prior to such
amendment),  against all expense, liability and loss (including attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid
in  settlement)  reasonably  incurred or  suffered by such person in  connection
therewith and such indemnification  shall continue as to a person who has ceased
to be a director,  officer,  employee or agent and shall inure to the benefit of
his or her heirs, executors and administrators;  provided, however, that, except
as provided in this Section 2, the  Corporation  shall indemnify any such person
seeking  indemnification  in  connection  with a  proceeding  (or part  thereof)
initiated  by  such  person  only if  such  proceeding  (or  part  thereof)  was
authorized  by  the  Board  of  Directors  of  the  Corporation.  The  right  to
indemnification  conferred in this Section 2 shall be a contract right and shall
include  the  right  to be paid by the  Corporation  the  expenses  incurred  in
defending any such proceeding in advance of its final  disposition as authorized
by the Board of  Directors;  provided,  however,  that if the  Delaware  General
Corporation  Law so  requires,  the  payment  of  such  expenses  incurred  by a
director,  officer,  employee or agent of the Company in his or her  capacity as
such in advance of the final disposition of a proceeding shall be made only upon
delivery to the Corporation of an undertaking, by or on behalf of such director,
officer,  employee or agent of the Company,  to repay all amounts so advanced if
it shall ultimately be determined that such director, officer, employee or agent
of the  Company  is not  entitled  to be  indemnified  under  this  Section 2 or
otherwise.

     SECTION  3. If a claim  under  Section 2 of this  Article IX is not paid in
full by the  Corporation  within 30 days after a written claim has been received
by the  Corporation,  the claimant may at any time thereafter bring suit against
the  Corporation to recover the unpaid amount of the claim and, if successful in
whole or in part,  the claimant shall be entitled to be paid also the expense of
prosecuting  such claim. It shall be a defense to any such action (other than an
action  brought  to  enforce a claim for  expenses  incurred  in  defending  any
proceeding in advance of its final disposition  where the required  undertaking,
if any is required,  has been tendered to the Corporation) that the claimant has
not met the standard of conduct  which makes it  permissible  under the Delaware
General  Corporation  Law for the  Corporation to indemnify the claimant for the
amount  claimed, but  the burden  of proving  such  defense shall  be on  the

                                      C-10

Corporation.  Neither the  failure of the  Corporation  (including  its Board of
Directors,  independent  legal  counsel,  or its  stockholders  to  have  made a
determination  prior to the commencement of such action that  indemnification of
the  claimant  is  proper  in the  circumstances  because  he or she has met the
applicable  standard of conduct set forth in the  Delaware  General  Corporation
Law, nor an actual  determination  by the  Corporation  (including  its Board of
Directors, independent legal counsel, or its stockholders) that the claimant has
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption  that the claimant has not met the  applicable  standard of
conduct.

     SECTION  4. The  right  to  indemnification  and the  payment  of  expenses
incurred in defending a proceeding in advance of its final disposition conferred
in this  Article IX shall not be  exclusive  of any other right which any person
may have or hereafter acquire under any statute, provision of the Certificate of
Incorporation,  these By-Laws,  agreement, vote of stockholders or disinterested
directors or otherwise.

     SECTION 5. The  Corporation  may maintain  insurance,  at its  expense,  to
protect itself and any director,  officer,  employee or agent of the Corporation
or another corporation,  partnership,  joint venture,  trust or other enterprise
against any such  expense,  liability  or loss,  whether or not the  corporation

Common Stock  Equivalent,  to the Equivalent  Price (provided that such price or
Equivalent Price is fixed on or before the execution date of the  agreement)(the
"Fixed Price") in the event that the Corporation, during the period beginning on
the date of the  agreement  and ending no later  than 90 days after the  closing

to another  investor at a price or Equivalent  Price,  as the case may be, below
the Fixed Price.
