Ph.D. ("Gordon") and VaxGen, Inc. ("VaxGen"), is effective September 6, 2001
(the "Effective Date"). In consideration of the mutual promises made herein,
VaxGen and Gordon agree as follows:

1. EMPLOYMENT. VaxGen hereby employs Gordon, and Gordon hereby accepts
employment with VaxGen, upon all of the terms and conditions described in this
Agreement. This Agreement supercedes, replaces and restates any and all prior
agreements between the parties hereto relating to the terms of Gordon's
employment with VaxGen, including any prior agreements concerning
confidentiality, non-disclosure and inventions.

2. WORK RESPONSIBILITIES. Subject to the terms of this Agreement, Gordon is
hereby employed in the position of Chief Executive Officer, reporting to the
Board of Directors of VaxGen (the "Board"), and shall perform the functions and
responsibilities of that position. VaxGen shall cause Gordon to be appointed to
the Board. Commencing 30 days or less after the Effective Date, Gordon shall
devote the whole of his professional time, attention and energies to the
performance of his work responsibilities. Gordon's position, job description,
duties and responsibilities may be modified from time to time in the sole
discretion of the Board. This Agreement shall not be interpreted to prohibit
Gordon, from engaging in the professional activities described in Appendix D
hereto.

3. COMPENSATION. As consideration for the services and covenants described in
this Agreement, VaxGen agrees to compensate Gordon during the term of this
Agreement in the following manner:

          A. Salary/Wages. VaxGen agrees to pay Gordon a base salary of $325,000
     per year. Gordon's salary, less required and authorized deductions, shall
     be paid in equal, periodic installments no less frequently than
     semi-monthly in accordance with VaxGen's then current payroll practices.
     The Compensation Committee of the Board will consider Gordon's salary
     annually for potential increase.

          B. Initial Option Grant and Subsequent Option Grants. On the Effective
     Date, Gordon shall be granted an option (the "Initial Option") to purchase
     400,000 shares of common stock of VaxGen at a per share exercise price
     equal to the fair market value of the common stock of VaxGen on the
     Effective Date in accordance with the form of grant used by VaxGen for
     grants made to its senior executive officers. The Initial Options shall be
     Incentive Stock Options to the maximum extent permitted by VaxGen's stock
     option plan. The Initial Option shall vest and become exercisable in
     installments at the rate of 100,000 shares on each of the following dates:
     (a) 30 days after the Effective Date, (b) the first (1st) anniversary of
     the Effective Date, (c) the second (2nd) anniversary of the Effective Date,
     and (d) the third (3rd) anniversary of the Effective Date; but only if in
     each case Gordon has been continuously employed with VaxGen from the
     Effective Date through the applicable vesting date, except as otherwise
     provided herein or under the terms of VaxGen's stock option plan. Except as
     otherwise provided herein, the Initial Option shall be subject to such
     terms and conditions, including provisions regarding post-

                                       19

     termination exercisability, as generally apply to stock options granted to
     other senior executive officers who participate in VaxGen's equity
     incentive plans as such terms and conditions are in effect on the Effective
     Date. In addition, Gordon will be eligible to receive an annual award of
     stock options, which will be issued, if at all, in accordance with the
     terms and conditions of this Agreement and VaxGen's stock option plan as in
     effect at the time of the award, in an amount to be determined in the sole
     discretion of the Board. In the event that Gordon's employment is
     terminated by the Company without Cause pursuant to paragraph 16A(4) below
     or by Gordon with Good Reason pursuant to paragraph 16A(5) below or
     following a Change in Control pursuant to paragraph 16D, then Gordon shall
     have three (3) years from the date of termination to exercise all options
     (both the Initial Option and any subsequently issued options) which are
     then vested or which vest as a result of this Agreement, provided however
     that in no event will Gordon be entitled to exercise such stock options
     after the expiration of 10 years from the date of grant of such options.

          C. Performance Bonus. Gordon is eligible to receive an annual
     performance bonus of up to thirty percent (30%) of his annual base salary
     in cash, VaxGen securities or a combination thereof, provided that no more
     than 50% of the performance bonus shall be paid in securities. Gordon shall
     be eligible to receive a prorated bonus for the 2001 calendar year. Such
     performance bonus shall be awarded, if at all, in the sole discretion of
     the Board. The Board and Gordon will mutually cooperate to establish annual
     performance objectives for Gordon. The Compensation Committee of the Board
     will consider Gordon's bonus annually for potential increase.

          D. Benefits. Gordon shall be entitled to employment benefits in
     accordance with policies established by or at the direction of the Board
     with respect to senior officers of VaxGen, including holidays, leaves of
     absence, health insurance, dental insurance, vacation and other benefits,
     if any, in accordance with any eligibility requirements, policies,
     procedures, or benefit plans adopted by VaxGen from time to time during the
     existence of this Agreement. Gordon's rights, or those of Gordon's
     dependents under any such benefits policies or plans, shall be governed
     solely by the terms of such policies or plans. VaxGen's employment
     benefits, and policies related thereto, are subject to termination,
     modification or limitation at VaxGen's sole discretion.

          E. Total Compensation. Gordon agrees that the compensation stated
     above constitutes the full and exclusive monetary consideration and
     compensation for all services rendered under this Agreement and for all
     promises and obligations under this Agreement.

          F. Relocation Benefits. In order to minimize the disruption to Gordon,
     VaxGen will provide financial assistance to Gordon in connection with his
     relocation from Massachusetts to the Bay Area as follows (the "Relocation
     Benefits"):

          (1)  Reimbursement of the cost of shipping household goods and
               personal effects, including automobiles, up to a maximum of
               $15,000, payable against receipts.

          (2)  VaxGen will provide Gordon with temporary housing in the Bay Area
               for ninety (90) days and will provide reimbursement for the use
               of a rental car

                                       20

<PAGE>


               for ninety (90) days, which may, if necessary, be extended with
               the Board's approval.

          (3)  Reimbursement of the cost of storage of household goods following
               their arrival in the Bay Area for 90 days, which may, if
               necessary, be extended with the Board's approval.

          (4)  The payment of a one-time relocation assistance payment of
               $45,000, which will be included with Gordon's first paycheck to
               assist, among other things, with miscellaneous travel and
               relocation expenses, including the cost of one-way air travel for
               Gordon and his spouse from Massachusetts to the Bay Area (which
               will not be otherwise reimbursed).

          (5)  Reimbursement of realtor commissions paid on the sale of Gordon's
               primary residence in Massachusetts.

          (6)  An interest-free loan in the principal amount of $80,000 (the
               "Loan") to assist with Gordon's purchase of a primary residence
               in the Bay Area. The proceeds of the Loan shall be made available
               to Gordon within three (3) business days of written notification
               by Gordon to VaxGen of his intention to sign an agreement to
               purchase a residence. The Loan will be forgiven by VaxGen at the
               rate of 25% per year for each of the first four full years of
               Gordon's employment by VaxGen. In the event Gordon's employment
               is terminated by VaxGen without Cause (as defined below) or upon
               a Change in Control (as defined below) or in the event Gordon
               resigns his employment for Good Reason (as defined below), the
               Loan shall be forgiven in its entirety. If Gordon's employment is
               terminated for Cause or Gordon resigns without Good Reason, the
               balance of the Loan shall become immediately due and payable.

     Gordon shall submit one or more expense reports, including copies of bills
     and receipts, in order to obtain reimbursement of the moving and relocation
     expenses described in items 1, 2, 3 and 5, above, in accordance with
     VaxGen's expense reimbursement policies and procedures.

     VaxGen and Gordon acknowledge and agree that the Relocation Benefits may be
     included in Gordon's gross income as compensation for services. Gordon
     shall be entitled to a "gross-up" payment with respect to those Relocation
     Benefits described in this Section 3(F)(1)-(5) in an amount that, after
     reduction for all applicable taxes on such "gross-up" payment, is equal to
     the amount of applicable taxes imposed on Gordon with respect to such
     Relocation Benefits.

          G. Business Expenses. VaxGen shall pay Gordon's reasonable business
     expenses, including expenses incurred for travel on VaxGen business, in
     accordance with the policies and procedures of VaxGen, as may be adopted or
     amended from time to time at VaxGen's sole discretion. If Gordon incurs
     business expenses under this Agreement,

                                       21

<PAGE>


     he shall submit monthly to VaxGen a request for reimbursement together with
     supporting documentation satisfactory to VaxGen.

4. VAXGEN POLICIES. Gordon agrees to abide by VaxGen's written policies, and
procedures that have been communicated or made available to him, as they may
from time to time be adopted or modified by VaxGen in its sole discretion.
VaxGen's written policies and procedures, including the Employee Handbook, shall
be binding on Gordon unless superseded by, or in conflict with, this Agreement.
Copies of written policies and procedures are available to Gordon in the offices
of VaxGen, and Gordon shall be responsible at all times to review, and make
himself familiar with, these policies and procedures.

5. WARRANTIES. Gordon hereby represents and warrants that he has not unlawfully
misappropriated any confidential, proprietary or trade secret information from
Gordon's prior employer or employers and, except to the extent such information
has become publicly available, will not knowingly disclose such information to
VaxGen or improperly use any such information on behalf of VaxGen. Gordon
acknowledges that VaxGen has specifically requested that, if Gordon has any such
confidential, proprietary or trade secret knowledge or information, Gordon not
use such information while employed by VaxGen for the benefit of VaxGen. Gordon
further warrants that by entering into this Agreement with VaxGen he is not
violating any of the terms, agreements or covenants of any previous employment
or association.

6. PRIOR INVENTIONS. Gordon acknowledges that, except for the inventions
disclosed on Appendix A, Gordon does not have any right or claim to any
invention, idea, process, formula, discovery, copyright, patent or other such
item or matter. No rights are hereby conveyed by Gordon to VaxGen with respect
to inventions, if any, made by Gordon prior to employment by VaxGen, which
inventions are listed in Schedule A, attached hereto.

7. SUBSEQUENT INVENTION DISCLOSURE. Gordon hereby agrees to promptly disclose to
VaxGen any and all inventions that he develops during the term of his
employment. Gordon will also disclose to the Board all inventions made,
conceived, reduced to practice, or developed by Gordon within six months of the
termination of his employment with VaxGen that resulted from his prior work with
VaxGen. Such disclosures shall be received by VaxGen in confidence and do not
extend the assignment of inventions disclosed beyond that required by law.

8. ASSIGNMENT OF INVENTIONS. Gordon hereby assigns and agrees to assign to
VaxGen or its designee, Gordon's entire right, title and interest in and to all
inventions, works of authorship, developments, concepts, discoveries, ideas,
trademarks and trade secrets, whether or not patentable or registrable under
copyright or other intellectual property laws ("Inventions") which Gordon may
solely or jointly develop, conceive or reduce to practice, during the period of
employment, except as provided in paragraph 10 below. Gordon agrees that all
such Inventions are the sole property of VaxGen. Gordon further agrees that all
such Inventions, including works of authorship, are "works for hire" for
purposes of VaxGen's rights under copyright laws. Gordon agrees to keep and
maintain adequate and current written records of all Inventions made by him
(solely or jointly with others) during the term of his employment with VaxGen.
The records will be in the form of notes, sketches, drawings, and any other
format that may be specified by VaxGen. The records will be available to and
remain the sole property of VaxGen

                                       22

<PAGE>


at all times. Gordon understands and agrees that the decision whether or not to
commercialize or market any Invention developed by him solely or jointly with
others is within VaxGen's sole discretion and for VaxGen's sole benefit and that
no royalty will be due to him as a result of VaxGen's efforts to commercialize
or market any such Invention. Gordon further agrees to perform, during and after
employment with VaxGen, all acts deemed necessary or desirable by VaxGen to
permit and assist VaxGen, at VaxGen's expense, in obtaining and enforcing the
full benefits, enjoyment, rights and title, throughout the world, of and to the
Inventions hereby assigned by Gordon to VaxGen as set forth above.

9. PATENT AND COPYRIGHT REGISTRATIONS. Gordon agrees to assist VaxGen, or its
designee, at VaxGen's expense, in every proper way to secure VaxGen's rights in
the Inventions and any copyrights, patents, trademarks, and trade secret rights
or other intellectual property rights in connection with any such Inventions in
any and all countries, including the disclosure to VaxGen of all pertinent
information and data with respect thereto, the execution of all applications,
specifications, oaths, assignments and all other instruments or papers which
VaxGen shall deem necessary in order to apply for and obtain such rights and in
order to assign and convey to VaxGen, its successors, assigns, and nominees the
sole and exclusive rights, title and interest in and to such Inventions, and any
copyrights, patents, trademark and other intellectual property rights relating
thereto. Gordon further agrees that his obligation to execute or cause to be
executed, when it is in his power to do so, any such instrument or papers shall
continue after the termination of this Agreement. If VaxGen is unable, because
of Gordon's mental or physical incapacity or for any other reason, to secure his
signature to apply for or to pursue any application for any United States or
foreign patents or copyright registrations covering Inventions or original works
of authorship assigned to VaxGen as above, then Gordon hereby irrevocably
designates and appoints VaxGen and its duly authorized officers and agents as
his agent and attorney in fact to act for and in his behalf and stead to execute
and file any such applications and to do all other lawfully permitted acts to
further the prosecution and issuance of letters patent or copyright
registrations thereon with the same legal force and effect as if executed by
Gordon.

10. INVENTIONS NOT ASSIGNED. The parties agree that the assignment of inventions
under this Agreement does not apply to an invention which qualifies fully for
protection under Section 2870 of the California Labor Code, which states that
"Any provision in an employment agreement which provides that an employee shall
assign, or offer to assign, any of his or her rights in an invention to his or
her employer shall not apply to an invention that the employee developed
entirely on his or her own time without using the employer's equipment,
supplies, facilities or trade secret information except for those inventions
that either: (1) relate at the time of conception or reduction to practice of
the invention to the employer's business, or actual or demonstrably anticipated
research or development of the employer; or (2) result from any work performed
by the employee for the employer."

11. CONFIDENTIAL, PROPRIETARY AND TRADE SECRET INFORMATION. During the course of
his employment, Gordon will come into possession of or acquire knowledge of
confidential, proprietary and trade secret information of VaxGen. Gordon hereby
covenants and agrees that he will not, either during his employment or at any
time thereafter, disclose any such confidential, proprietary or trade secret
information to any person, firm, corporation, association, partnership or other
entity (other than those in VaxGen's organization

                                       23

<PAGE>

qualified and authorized to receive such information) for any purpose or reason
whatsoever. Such confidential and proprietary information shall be deemed to
include, but not be limited to, manuals, discs, tapes, and summaries or
originals of any papers, documents, plans, specifications, client lists,
contracts, licenses or licensing agreements, data bases, or portions thereof,
related to the research and development, products or operations of VaxGen,
provided that such information is confidential, proprietary or falls within the
definition of a "trade secret" under the Uniform Trade Secrets Act. Gordon
specifically agrees that he will not make use of any such confidential or
proprietary information for his own purpose, or for the benefit of any person,
firm, corporation or other entity except VaxGen. Gordon will abide by VaxGen's
policies and procedures, as established from time to time for the protection of
its trade secrets and confidential information.

12. RETURN OF PROPERTY. All confidential, proprietary and trade secret
information, and all other documents, records, apparatus, equipment and other
physical property which is furnished to or obtained by Gordon in the course of
employment with VaxGen, shall be and remain the sole property of VaxGen. Gordon
agrees that upon request by VaxGen or the termination of Gordon's employment
(whichever occurs first), Gordon shall return all such property, and agrees not
to make or retain copies, reproductions or summaries of any such property
without the express written consent of VaxGen.

13. NON-SOLICITATION, ANTI-RAIDING. For a period of one (1) year immediately
following the termination of his employment, Gordon agrees that he will not,
either directly or indirectly, (a) attempt to recruit, solicit or take away any
of the employees of VaxGen who worked for VaxGen at any time during the term of
this Agreement; make known to any person, firm or corporation the names or
addresses of, or any information pertaining to, any current or former employees
of VaxGen; (b) use any confidential or proprietary information to attempt to
call on, solicit or take away any clients of VaxGen or any other persons,
entities, or corporations with which VaxGen has had or contemplated any business
transaction or relationship during Gordon's employment with VaxGen, including,
but not limited to, investments, licenses, joint ventures, and agreements for
development..

14. EQUITABLE RELIEF. Gordon and VaxGen each agree that in the event of a breach
or threatened breach of paragraphs 8 through 13 of this Agreement each party
will not have an adequate remedy at law. Thus, in the event of such a breach or
threatened breach by one party, the other party will be entitled to such
equitable and injunctive relief in a court of law as may be available to prevent
and restrain a breach of the provisions of paragraphs 8 through 13. Said
availability to obtain injunctive relief will not prevent either party from
pursuing any other equitable or legal relief, including the recovery of damages
from such breach or threatened breach.

15. AT-WILL EMPLOYMENT. Gordon understands and agrees that employment at VaxGen
is at-will. This means that, for any reason or no reason, Gordon's employment
may be terminated, with or without cause, at any time by either Gordon or by
VaxGen, subject to the severance and notice provisions contained in Section 16
below. Nothing in this or any other document or statement shall limit the right
of VaxGen to terminate Gordon's employment at-will. Only the Board has the
authority to amend this Agreement on behalf of VaxGen, and then

                                       24

<PAGE>

only in a writing that is signed by both Gordon and VaxGen pursuant to authority
expressly granted by the Board.



16.  TERMINATION OF EMPLOYMENT.

     A.   Subject to the survivability provisions of Section 18 below, Gordon's
          employment under this Agreement and all compensation and benefits
          provided for herein shall terminate upon the occurrence of any of the
          following events.

               (1) Death: In the event of Gordon's death, the termination shall
               be effective upon the date thereof.

               (2) Disability: In the event that Gordon should become
               "disabled," VaxGen may terminate Gordon's employment under this
               Agreement. For purposes of this paragraph "disabled" shall mean
               Gordon's inability, despite reasonable accommodation, to perform
               the essential duties of his position for a period of five (5)
               consecutive months, and failure to resume the performance of such
               duties on a full-time basis within thirty (30) days of notice
               from VaxGen of intent to terminate this Agreement on such
               grounds. The termination shall be effective upon the date
               specified in VaxGen's notice to Gordon as provided for herein.
               Any base salary payable to Gordon by VaxGen may be offset by any
               benefits paid to Gordon under any applicable short-term or
               long-term disability plan.

               (3) Cause: VaxGen may terminate Gordon's employment under this
               Agreement upon the occurrence of "cause" for termination as
               herein defined. "Cause" shall mean (a) Gordon's fraud,
               misappropriation, embezzlement or other willful commission of a
               dishonest or unlawful act that has the effect of materially
               injuring VaxGen or its reputation, (b) Gordon's conviction of a
               crime involving moral turpitude or a felony, (c) Gordon's willful
               or reckless violation of VaxGen's written policies or procedures
               that has the effect of materially injuring VaxGen, or Gordon's
               breach of the confidential information and invention assignment
               provisions of this Agreement, and, if any such violation or
               breach under this Section 16.A(3)(c) is curable, Gordon's failure
               to cure such violation or breach within 15 business days of
               receiving notice of such violation or breach from the Board, or
               (d) Gordon's habitual failure to perform his job duties, as
               determined by the Board in its reasonable judgment, and after
               notice of such failure has been given to Gordon by the Board and
               Gordon has had a 15 business-day period within which to cure such
               failure. The Parties acknowledge that the reference to a "for
               Cause" termination herein does not alter the employment at-will
               relationship, but merely sets forth circumstances under which
               VaxGen has no obligation to pay severance to Gordon. The
               termination shall be effective upon the date specified in
               VaxGen's notice to Gordon.

                                       25

<PAGE>

               (4) Without Cause: Either VaxGen or Gordon may terminate Gordon's
               employment under this Agreement without Cause at any time upon
               thirty (30) days written notice to the other party. The
               termination shall be effective upon the date specified in the
               notice given pursuant hereto.

               (5) By Gordon with Good Reason: Gordon may terminate his
               employment under this Agreement for Good Reason (i) in the event
               VaxGen breaches a material term hereof and, after receiving
               written notice from Gordon detailing the specific provision
               allegedly breached, does not remedy said breach within thirty
               (30) days of receiving notice, (ii) there is a demotion of Gordon
               from the position of Chief Executive Officer or the assignment of
               job duties or responsibilities materially inconsistent with such
               position, (iii) VaxGen moves Gordon's principal place of business
               more than thirty-five (35) miles from VaxGen's current principal
               place of business at 1000 Marina Blvd, Brisbane, California, (iv)
               there is a reduction in Gordon's then-current base salary and/or
               performance bonus opportunity, or (v) there is a material and
               substantial reduction in the aggregate of Gordon's employee
               benefits. The termination shall be effective on the date
               specified in the notice given hereunder, which date shall not be
               earlier than the date such notice is given nor more than 30 days
               after the date such notice is given.

     B.   In the event that Gordon's employment under this Agreement is
          terminated by VaxGen under paragraphs (A)(1), (A)(2) or (A)(3) above,
          or by Gordon under paragraph (A)(4) above, no severance pay will be
          due to Gordon; however Gordon shall be entitled to payment for any
          earned but unpaid base salary through the date of termination as well
          as payment for any accrued but unused vacation time and any accrued
          employee benefits, subject to the terms of the applicable employee
          benefit plans.

     C.   In the event that Gordon's employment under this Agreement is
          terminated by VaxGen under paragraph (A)(4) above or by Gordon under
          paragraph (A)(5) above, Gordon shall be entitled to receive: (i)
          severance pay in the amount of twelve (12) months of his then-existing
          annual base salary (such severance being limited strictly to annual
          base salary and will not include any amount paid or payable as a bonus
          or stock option grant), less required and authorized deductions,
          payable as a lump sum for six months' base salary and the other six
          months' base salary shall be paid on VaxGen's ordinary payroll cycles
          until fully paid out; and (ii) accelerated vesting of all his
          outstanding stock options to fully vested status as of the date of
          termination.

     D.   Gordon shall be entitled to the severance benefits provided for in
          16.C above if, within twelve (12) months following a Change in Control
          (as defined below), VaxGen or its successor in interest terminates
          Gordon's employment for any reason other than for Cause (as defined
          above) or Gordon terminates his employment on account of any of the
          following: (i) in the event VaxGen breaches a material term hereof
          and, after receiving written notice from Gordon detailing the specific
          provision allegedly breached, does not remedy said breach

                                       26

<PAGE>


          within thirty (30) days of receiving notice; or (ii) there is a
          material reduction in Gordon's job duties or responsibilities,
          including, without limitation, demotion from the position of Chief
          Executive Officer; or (iii) VaxGen or its successor in interest moves
          Gordon's principal place of business more than thirty-five (35) miles
          from VaxGen's current principal place of business at 1000 Marina Blvd,
          Brisbane, California; or (iv) there is a reduction in Gordon's
          then-current base salary and/or performance bonus opportunity; or (v)
          there is a material and substantial reduction in the aggregate of
          Gordon's employee benefits.

     E.   For purposes of this Agreement, a "Change in Control" shall be deemed
          to have occurred if: (i) there is an acquisition by any individual,
          entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of
          the Securities Exchange Act of 1934, as amended (the "Exchange Act"))
          (for the purposes of this Section, a "Person") of beneficial ownership
          (within the meaning of Rule 13d-3 promulgated under the Exchange Act)
          of 50% or more of the voting power of the then outstanding voting
          securities of VaxGen entitled to vote generally in the election of
          directors (the "Outstanding Company Voting Securities"); provided,
          however, that for purposes of this subsection (a), any acquisition by
          any employee benefit plan (or related trust) sponsored or maintained
          by VaxGen or any corporation controlled by VaxGen shall not constitute
          a Change in Control; or (ii) individuals who, as of the date hereof,
          constitute the Board (the "Incumbent Board") cease for any reason to
          constitute at least a majority of the Board; provided, however, that
          any individual (other than an individual whose initial assumption of
          office occurs as a result of an actual or threatened solicitation of
          proxies or consents by or on behalf of a Person other than the Board)
          who becomes a director subsequent to the date hereof whose election or
          nomination for election by VaxGen's shareholders was approved by a
          vote of at least a majority of the directors then comprising the
          Incumbent Board shall be considered as though such individual were a
          member of the Incumbent Board; or (iii) there is a consummation of a
          reorganization, merger or consolidation or sale or other disposition
          of all or substantially all of the assets of VaxGen (a "Business
          Combination") unless, following such Business Combination, (a)
          individuals and entities who were the beneficial owners of the
          Outstanding Company Voting Securities immediately prior to such
          Business Combination beneficially own, directly or indirectly, more
          than 50% of the voting power of the then Outstanding Company Voting
          Securities of the corporation resulting from such Business Combination
          (including, without limitation, a corporation which as a result of
          such transaction owns VaxGen or all or substantially all of VaxGen's
          assets either directly or through one or more subsidiaries) and (b) at
          least a majority of the members of the board of directors of the
          corporation resulting from such Business Combination were members of
          the Incumbent Board at the time of the execution of the initial
          agreement, or of the action of the Board, providing for such Business
          Combination; or (iv) approval by the shareholders of VaxGen of a
          complete liquidation or dissolution of VaxGen.

                                       27

<PAGE>


     F.   In the event Gordon's employment with VaxGen is terminated, Gordon
          agrees that he will, unless otherwise requested by the Board, resign
          his position on the Board within ten (10) days of the date his
          employment is terminated.

17. INDEMNIFICATION. VaxGen shall maintain, for the benefit of Gordon, director
and officer liability insurance in form at least as comprehensive as, and in an
amount that is at least equal to, that maintained by VaxGen as of the Effective
Date of this Agreement for its other officers and directors. In addition, VaxGen
shall indemnify Gordon against liability as an officer and director of VaxGen or
any subsidiary or affiliate of VaxGen to the maximum extent permitted by
applicable law. Gordon's rights under this Paragraph 17 shall continue so long
as he may be subject to such liability, whether or not his employment may have
terminated prior thereto.

18. SURVIVABILITY. The respective rights and obligations of the Parties
hereunder, including, without limitation, Sections 7, 8, 9, 10, 11, 12, 13, 14,
16(C), 17, 19 and 28 of this Agreement, shall, to the extent necessary, survive
any termination of Gordon's employment or this Agreement.

19. GOVERNING LAW. This Agreement shall be construed in accordance with and
governed by the laws of the State of California without regard to its conflict
of law rules. This Agreement shall be interpreted in accordance with the plain
meaning of its terms and not strictly for or against either party.

by VaxGen, and contains all of the covenants and agreements of any kind
whatsoever between the parties with respect to such employment. Each party
acknowledges that no representations, inducements, promises or agreements,
whether oral or written, express or implied, have been made by either party or
anyone acting on behalf of a party, that are not incorporated herein and that no
agreement or promise not contained herein shall be valid or binding.

21. WAIVER. The failure of either party to insist, in any one or more instances,
upon performance of the terms or conditions of this Agreement shall not be
construed as a waiver or a relinquishment of any right granted under this
Agreement or of the future performance of any such term, covenant or condition.

22. INVALIDITY. Should any provision, portion or part of this Agreement be held
by a court of competent jurisdiction to be invalid, void or unenforceable, the
remaining provisions, portions or parts shall be unaffected and shall continue
in full force and effect, and said invalid, void or unenforceable provision(s),
portion(s) or part(s) shall be deemed not to be part of this Agreement.

23. NO THIRD PARTY BENEFICIARIES. This Agreement is not intended by either party
to create any third-party beneficiaries, and shall not be so construed in any
proceeding. The sole parties to this Agreement are Gordon and VaxGen, and it is
their mutual intent that they alone shall have standing to enforce the
provisions of this Agreement, subject to the provisions of Section 26 below.

24. VOLUNTARY AGREEMENT. Gordon and VaxGen represent and agree that each has
reviewed all aspects of this Agreement, has carefully read and fully understands
all provisions of this Agreement, and is voluntarily entering into this

Agreement.

26. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and inure to
the benefit of and shall be enforceable by and against Gordon's heirs,
beneficiaries and legal representatives. It is agreed that the rights and
obligations of Gordon may not be delegated or assigned except as specifically
set forth in this Agreement. In the event of a Change in Control (as defined
above), VaxGen may assign its rights and obligations under this Agreement to its
successor-in-interest, and in that event such successor-in-interest shall be

                          ALTERNATIVE DISPUTE AGREEMENT

o    Agreement To Arbitrate

     In the event that any employment dispute arises between VaxGen, Inc.
("VaxGen") and Lance K. Gordon, Ph. D. ("Gordon"), the parties involved will
make all efforts to resolve any such dispute through informal means. However, if
within thirty (30) days of the event giving rise to the dispute, these informal
attempts at resolution fail and if the dispute arises out of or is related to
Gordon's Employment Agreement, Gordon's employment, the termination of Gordon's
employment or alleged unlawful discrimination, including but not limited to
sexual or other unlawful harassment (an "Arbitrable Dispute"), VaxGen and Gordon
will submit the dispute to final and binding arbitration, except as set forth in
Paragraphs 7-14 of the Employment Agreement.

     The parties expressly understand and agree that arbitration is the
exclusive remedy for all such Arbitrable Disputes; with respect to such
disputes, no other action may be brought in court or any other forum (except
actions to compel arbitration or enforce an award issued hereunder). THIS
ALTERNATIVE DISPUTE RESOLUTION ("ADR") AGREEMENT IS A WAIVER OF THE PARTIES'
RIGHTS TO A CIVIL COURT ACTION FOR A DISPUTE RELATING TO BREACH OF THE PARTIES'
EMPLOYMENT AGREEMENT, TERMINATION OF THAT EMPLOYMENT OR ALLEGED UNLAWFUL
DISCRIMINATION, WHICH INCLUDES RETALIATION OR SEXUAL OR OTHER UNLAWFUL
HARASSMENT; ONLY AN ARBITRATOR, NOT A JUDGE OR JURY, WILL DECIDE THE DISPUTE.

     Arbitrable Disputes arising out of or related to employment, or the
termination of such employment or alleged unlawful discrimination, including
retaliation or sexual or other unlawful harassment, shall include, but not be
limited to, the following: alleged violations of federal, state and/or local
constitutions, statutes or regulations; claims based on any purported breach of
contractual obligation, including breach of the covenant of good faith and fair
dealing; and claims based on any purported breach of duty arising in tort,
including violations of public policy.

     The following types of employment disputes are not subject to this ADR
Agreement: (1) disputes related to workers' compensation and unemployment
insurance; (2) claims for benefits covered by a separate benefit plan that
provides for arbitration; and (3) claims subject to Sections 7 through 14 of the
Employment Agreement. Also, nothing in the Employment Agreement or in the ADR
Agreement shall be construed as precluding Gordon from filing a charge with the
Equal Employment Opportunity Commission ("EEOC"), the National Labor Relations
Board ("NLRB") or other federal, state or local agencies, seeking administrative
assistance in resolving claims. However, any claim that cannot be resolved
administratively through such an agency shall be subject to the Employment
Agreement and the ADR Agreement.

o    Request For Arbitration

     o    Attempt At Informal Resolution Of Disputes

     Prior to the submission of any Arbitrable Dispute to arbitration, Gordon
and VaxGen shall attempt to resolve the dispute informally as set forth below.

     Gordon and VaxGen will select a mediator from a list provided by the
Federal Mediation and Conciliation Service or other similar agency who will
assist the parties in attempting to reach a settlement of the dispute. The
mediator may make settlement suggestions to the Parties but shall not have the
power to impose a settlement upon them. If the dispute is resolved in mediation,
the matter shall be deemed closed. If the dispute is not resolved in mediation
and goes to the next step (binding arbitration), any proposals or compromises
suggested by either of the parties or the mediator shall not be referred to in
or have any bearing on the arbitration procedure. The mediator cannot also serve
as the arbitrator in the subsequent proceeding unless all parties expressly
agree in writing. o Arbitration Procedures

     The party desiring arbitration, whether Gordon or VaxGen, must submit a
"Request For Arbitration" in writing to the other party within the time period
required by the law that applies to the claim under the applicable statute of
limitations. If the "Request for Arbitration" is not submitted in accordance
with the aforementioned time limitations, the party failing to do so will not be
able to bring his claims to this or any other forum. The requesting party may
use a "Request for Arbitration" form supplied by VaxGen (Appendix C).
Alternatively, the requesting party may create a "Request For Arbitration" form
that, unless otherwise required by law, clearly states "Request For Arbitration"
at the beginning of the first page and includes the following information:

     1. A factual description of the dispute in sufficient detail to advise the
other party of the nature of the dispute;

     2. The date when the dispute first arose;

     3. The names, work locations and telephone numbers of any individuals,
including employees or supervisors, with knowledge of the dispute; and

     4. The relief requested by requesting party.

     The responding party may submit counterclaim(s) in accordance with
applicable law. o Selection Of The Arbitrator

     All disputes will be resolved by a single Arbitrator, the Arbitrator will
be mutually selected by VaxGen and Gordon. If the parties cannot agree on an
Arbitrator, then a list of seven (7) arbitrators, experienced in employment
matters, shall be provided by the Judicial Arbitration Mediation Services
("JAMS/Endispute"). The Arbitrator will be selected by the

                                       33

<PAGE>

parties who will alternately strike names from the list. The last name remaining
on the list will be the Arbitrator selected to resolve the dispute. Upon
selection, the Arbitrator shall set an appropriate time, date and place for the
arbitration, after conferring with the parties to the dispute.

     o    The Arbitrator's Authority

          The Arbitrator shall have the powers enumerated below:

          1. Ruling on motions regarding discovery, and ruling on procedural and
evidentiary issues arising during the arbitration.

          2. Ruling on motions to dismiss and/or motions for summary judgment
applying the standards governing such motions under the Federal Rules of Civil
Procedure.

          3. Issuing protective orders on the motion of any party or third party
witness. Such protective orders may include, but are not limited to, sealing the
record of the arbitration, in whole or in part (including discovery proceedings
and motions, transcripts, and the decision and award), to protect the privacy or
other constitutional or statutory rights of parties and/or witnesses.

          4. Determining only the issue(s) submitted to him/her. The issue(s)
must be identifiable in the "Request For Arbitration" or counterclaim(s). Except
as required by law, any issue(s) not identifiable in those documents is outside
the scope of the Arbitrator's jurisdiction and any award involving such
issue(s), upon motion by a party, shall be vacated.

     o    Discovery

          The discovery process shall proceed and be governed by the standards
of the California Code of Civil Procedure and the Federal Arbitration Act. Each
party may obtain discovery necessary to adequately explore and arbitrate their
respective claims. The Arbitrator shall have the power to enforce the
aforementioned discovery rights and obligations by the imposition of the same
terms, conditions, consequences, liabilities, sanctions and penalties as can or
may be imposed in like circumstances in a civil action under the California Code
of Civil Procedure, except the power to order the arrest or imprisonment of a
person.

     o    Hearing Procedure

          The hearing shall be held at a location mutually agreed upon by the
parties, or as determined by the Arbitrator in the absence of an agreement, and
shall proceed according to the current version of the American Arbitration
Association's "National Rules for the Resolution of Employment Disputes" (the
"Rules") with the following amendments:

          1. The Arbitrator shall rule at the outset of the arbitration on
procedural issues that bear on whether the arbitration is allowed to proceed.

          2. Each party has the burden of proving each element of its claims or
counterclaims, and each party has the burden of proving any of its affirmative
defenses.

                                       34

<PAGE>

          3. In addition to, or in lieu of closing argument, either party shall
have the right to present a post-hearing brief, and the due date for exchanging
any post-hearing briefs shall be mutually agreed on by the parties and the
Arbitrator, or determined by the Arbitrator in the absence of agreement.

          4. The Rules shall otherwise be modified to the extent necessary to be
consistent with applicable law.

     o    Substantive Law

          1. The parties agree that they will be afforded the identical legal,
equitable, and statutory remedies as would be afforded them were they to bring
an action in a court of competent jurisdiction.

          2. The applicable substantive law shall be the law of the State of
California and/or federal law. Choice of substantive law in no way affects the
procedural aspects of the arbitration, which are exclusively governed by the
provisions of this ADR Agreement.

     o    Opinion And Award

          The Arbitrator shall issue a written opinion and award, in conformance
with the following requirements:

          1. The opinion and award must be signed and dated by the Arbitrator.

          2. The Arbitrator's opinion and award shall decide all issues
submitted.

          3. The Arbitrator's opinion and award shall set forth the findings of
fact and conclusions of law supporting each part of the opinion.

          4. The Arbitrator shall have the same authority to award remedies,
damages and costs as provided to a judge and/or jury under parallel
circumstances.

     o    Enforcement Of Arbitrator's Award

          Following the issuance of the Arbitrator's decision, any party may
petition a court to confirm, enforce, correct or vacate the Arbitrator's opinion
and award under the Federal Arbitration Act, and/or applicable State law. o Fees
And Costs

          Unless otherwise required by law, fees and costs shall be allocated in
the following manner:

          1. Each party shall be responsible for its own attorneys' fees, except
as otherwise provided by law for the particular claim(s) at issue.

                                       35

<PAGE>

          2. VaxGen shall pay the entire cost of the arbitrator's services, the
facility in which the arbitration is to be held, and any similar costs that
Gordon would not have otherwise incurred if the dispute were adjudicated in a
court of law rather than through arbitration.

          3. VaxGen shall pay the entire cost of a court reporter to transcribe
the arbitration proceedings. Each party shall advance the cost for said party's
transcript of the proceedings. Each party shall advance its own costs for
witness fees, service and subpoena charges, copying, or other incidental costs
that each party would bear during the course of a civil lawsuit.

          4. Each party shall be responsible for its costs associated with
discovery, except as required by law or court order.

o    Severability

          Each term, clause and provision of this ADR Agreement is separate and
independent, and should any term, clause or provision of this ADR Agreement be
found to be invalid or unenforceable, the validity of the remaining terms,
clauses, and provisions shall not be affected. As to those terms, clauses and
provisions found to be invalid or unenforceable, they shall be replaced with
valid and enforceable terms, clauses or provisions or shall be modified, in
order to achieve, to the fullest extent possible, the economic, business and
other purposes of the invalid or unenforceable terms, clauses or provisions.

Lance K. Gordon:  Involvement with outside organizations

     1.   Cambrex Corporation (NYSE: CBM); I have been a member of the
          Scientific Advisory Committee (SAC) of BioScience Contract Production
          since approximately 1990. BioScience was acquired by Cambrex on April
          30, 2001. Cambrex has continued the BioScience SAC which meets
          approximately every two months. Travel is paid by Cambrex.

     2.   PATH; PATH is a non-profit with substantial funding from the Gates
          Foundation active in global vaccines initiatives. I am a consultant to
          PATH in regard to their initiative to secure a new vaccine for
          epidemic Group A meningitis in Sub-Saharan Africa. The project is a
          priority for GAVI and is joint between PATH, The World Health
          Organization and the US Centers for Disease Control and Prevention. I
          am both a technical advisor and a member of the committee negotiating
          with potential manufacturers. There are no regularly scheduled
          meetings of the meningitis task force. I believe my role will
          essentially end once PATH issues a contract.

     3.   The World Bank; I am a consultant to the World Bank in regard to their
          vaccine initiatives. I have two current roles.
          a) One of these is as a member of the "Brainstorming Group", The
          Brainstorming Group are the organizers of the "Out of The Box" (OOTB).
          OOTB is composed of 10 very senior international leaders from
          industry, government and finance. OOTB is chartered to be the
          strategic and operational advisors to the Board of Directors of GAVI
          (Global Alliance for Vaccines and Immunization). It is currently
          anticipated that the Brainstorming Group would meet twice a year. b) I
          am currently on the Vaccine Procurement Group of the GAVI Financing
          Task Force. This group coordinates how vaccines are purchased for
          approximately 60- 70% of the world's children.

     4.   Sabin Vaccine Institute: I am a Senior Scientific Advisor to the Sabin
          Vaccine Institute. I have no regularly scheduled responsibilities with
          the Institute. I have attended two of their annual events for the past
          several years. Each year, typically in June they have a black tie
          award dinner in NYC honoring outstanding contributors to the world of
          vaccines. The second is a colloquium held in October at Cold Spring
          Harbor in New York State. This year I am co-chairman for the Cold
          Spring Harbor conference.
          Earlier this year the Sabin Institute has asked me to write a book on
          the history of the development of the vaccine for Haemophilus
          influenzae b. I developed the first of the conjugate vaccines now
          universally used in the developed world and finding it's way into the
          developing countries. This is an in progress background activity.
          Sabin has offered to hire a professional writer to carry much of the
          load.

     5.   I am a member of the National Institutes of Health Task force on
          malaria. This is a recent appointment and I'm told that they
          anticipate only one on-site meeting a year in the Washington DC area.

     6.   US Medicine Institute: USMI is a Washington DC based not-for-profit
          organization whose principal activity is holding policy forums for
          government leaders in DC. I am a Senior Fellow of the US Medicine
          Institute. As a Senior Fellow I contribute to their planning
          activities but have no established responsibilities. Annually they run
          a "Leadership Course" principally for senior government personnel.
          I've been asked to help structure a three-day portion of the course
          for February 2002 focusing on the vaccine manufacture in the US.

     7.   I have agreed to write a chapter on vaccines manufacture for third
          edition of a textbook on vaccines, "New Generation Vaccines". The
          senior editor of the textbook is Myron M. Levine, M.D. It is published
          by Marcel Dekker, Inc.
