         WHEREAS:

         A. The Corporation is a corporation organized under the laws of the
            State of Delaware, and is engaged in the business of developing and
            manufacturing pharmaceutical products and services; and

         accepts such employment as Chief Executive Officer and Chief Scientific
         Officer of Corporation upon the terms and provisions set forth in this
         Agreement. Executive shall report only to the Board of Directors of the
         Corporation ("the Board") subject to the directions of the Board and
         shall have general supervision, direction and control of the business,
         officers and employees of the Corporation. All officers and employees

         the Corporation as necessary to faithfully discharge the duties and
         responsibilities of his office.

<PAGE>   2

             Executive may participate in other business and act as a director
         of any profit or nonprofit corporation, so long as such activity is not
         competitive with the business of the Corporation in any material
         respect and does not materially detract from the performance of his
         duties as a full time executive of the Corporation.

         1.2 Board Seat

             During the term hereof, including any extensions, Executive shall

and shall continue until December 31, 2003 unless sooner terminated as hereafter
provided. Thereafter, this Agreement will automatically renew for one (1) year
periods, unless either party gives to the other written notice at least ninety

             shall be as set forth in the separate option agreements. To the
             extent that Corporation does not have available options in its

             new plans as promptly as possible to provide sufficient options for
             such option grants. Corporation shall use its best efforts to
             prepare and submit for approval by its directors and its
             stockholders at the 2001 Annual Meeting of Stockholders a new
             option plan which would provide sufficient options to allow
             Corporation to meet its contractual obligations to Executive herein
             and to provide for potential grants of stock options to other key
             employees.

                 (B) Executive shall be considered for additional grants of
             options, SAR's, phantom stock rights and any similar option or
             securities compensation when and as such grants are considered for
             other executives or employees of the Corporation, but any grant is
             wholly at the discretion of the Board.

                 (C) For all purposes of this Agreement, a "change of control"
             shall mean and shall be deemed to have occurred if:

                     (1) There shall be consummated (x) any consolidation or
                  merger of the Corporation with another corporation or entity
                  and as a result of such consolidation or merger, a majority of
                  the outstanding voting securities of the surviving or
                  resulting corporation or entity shall be owned in the
                  aggregate by persons who were not stockholders of the
                  Corporation prior to the merger or consolidation (excluding
                  the affiliates of the acquiror who acquired their shares
                  within one hundred eighty (180) days prior to such merger or
                  transfer (or in one transaction or a series of related
                  transactions) of all, or substantially all, of the assets of
                  the Corporation, or

                     (2) The stockholders of the Corporation shall have approved
                  any plan or proposal for the liquidation or dissolution of the
                  Corporation; or

                     (3) Any "person" (as such term is used in the Sections
                  13(d) and 14 (d) (2) of the Securities Exchange Act of 1934),
                  shall have become the beneficial owner (within the meaning of
                  Rule 13d-3 under the Exchange Act) of forty percent (40%) or
                  more of the Corporation's outstanding common stock, without
                  the prior approval of the Board, or

                     (4) During any period of two (2) consecutive years,
                  individuals who at the beginning of such period constituted
                  the entire Board of Directors shall have ceased for any reason
                  to constitute a majority thereof unless the election, or the
                  nomination for election by the Corporation's stockholders, of
                  each new Director was approved by vote of the Directors then
                  still in office who were Directors at the beginning of the
                  period.

                 (D) Retirement of Executive

                 Any options held by Executive will become fully vested at the
             time that Executive terminates employment due to his retirement.
             Retirement is defined as the voluntary termination of employment by
             the Executive as a result of the Executive having reached the
             retirement age as established by the Corporation or age 65,
             whichever occurs first or, subsequent to thereto, voluntarily
             terminates his employment.

         Options, and Additional Benefits then being provided to Executive not

         the Corporation may, in its discretion, increase the Base Salary, award
         a Bonus, grant Stock Options and Additional Benefits.

         be defined as any of the following, provided however, that the board of
         directors of the Corporation by a duly adopted resolution has
         determined the presence of such cause in good faith: (i) Executive's

         (ii) Executive's conviction by, or entry of a plea of guilty in, a
         court of competent jurisdiction for a felony; or, (iii) Executive's
         commission of an act of fraud or willful misconduct or gross negligence
         in the performance of his duties

             Not withstanding the foregoing, Executive shall not be terminated
         for "cause pursuant to the clauses above, unless and until Executive

         details on the bases for such termination and has had an opportunity to
         be heard before at least a majority of members of the board of

         such an opportunity if written or telephonic notice is given at least
         ten (10) days in advance of a meeting.

         6.4 Termination without Cause

             Without cause. Notwithstanding any other provision of this section,

         employment with the Corporation without cause at any time, but any such
         termination shall be without prejudice to Executive's rights to receive
         Base Salary, and Additional Benefits provided; under this Agreement for
         the greater of two (2) years or the remaining term as set forth in
         paragraph 2 above of this Agreement and, except as provided in the
         proviso below, Executive shall be vested in all options granted to him,
         and shall have one (1) month for each month of Executive's tenure, with
         a minimum of six (6) months and a maximum of one (1) year, to exercise
         all vested options; provided, further, if the Board determines that
         Executive's employment is being terminated for the reason that the
         shared expectations of Executive and the Board are not being met; in
         the Board's judgement, then Executive's vesting as shall occur during a
         period following the date of termination of Executive's employment
         equal to the number of months of Executive's tenure with the
         Corporation, with a minimum of six (6) months and a maximum of one (1)
         year, with the right to exercise for the same period plus thirty (30)
         days. The continued vesting and exercise rights relative to all options
         granted to Executive shall be subject to the same limitations as set
         forth in the immediately preceding sentence. If Executive is terminated
         without cause, Executive may elect to receive a lump sum payment
         representing the aggregate cash compensation (including salary, bonus,
         auto allowance and any other cash or equivalent compensation, other
         than continued vacation accrual). Such lump sum payment shall be made

                                       7

<PAGE>   8

         total and permanent by a physician selected by the Corporation or its
         insurers and reasonably acceptable to Executive or Executive's legal
         representative. If Executive shall become disabled, Executive's
         employment may be terminated; by written notice to Executive. In the
         event of the death of Executive, all compensation hereunder shall be
         paid based on value at time of death.

         6.6 By Executive Without Cause

             By Executive at any time upon ninety (90) days' notice to
         Corporation. Executive shall not be entitled to any severance in the
         event of such a termination.

7. CHANGE OF CONTROL

         If there should occur a "change of control" of the Corporation (or any
successor), as defined in paragraph 3.4 (C) hereof, and Executive's employment
is terminated (other than by Executive) or Executive is adversely affected in
terms of overall compensation, benefits, title, authority, reports reporting
relationships, location of employment or similar matters, then Executive,
without limitation on any other rights hereunder, may, within six (6) months
after receiving notice of such event, elect to resign from full time service to
the Corporation. In the event of such election by Executive, Executive shall be
provided with senior executive outplacement services at an outplacement or
executive search firm of Executive's selection (and reasonably acceptable to
Corporation), and the cash compensation and all benefits to which Executive is
entitled hereunder shall be discontinued twenty-four (24) months after the date
of election (or earlier, if a lump sum payment of cash compensation is
specified). Executive, at his election, shall have the right to request and, if
requested, shall be paid the full cash value of all amounts of cash compensation
due for the 24-month period (including salary, approved bonus, auto allowance,
and any other cash or equivalent compensation) in a lump sum, such lump sum
payment shall be made not later than ten (10) days after Executive gives notice
to the Corporation of his lump sum election. In the event of such election, all
insurance and noncash benefits shall cease. All options granted to Executive
shall vest to the extent provided in paragraph 6.4 above. In addition, if an
acquirer of 100% of the Corporation stock is itself a publicly held company, the
Corporation shall make reasonable efforts to negotiate that Executive shall have
the right, but not the obligation, to convert all his Corporation vested options
into options on the acquirer's stock and shall have two (2) years to exercise
those options, but Corporation shall have no obligation to Executive if it fails
to secure such rights or concludes that pursuing such rights would materially
prejudice the interest of the stockholders of the Corporation.

8. BREAKUP AND DISPOSITION OF CORPORATION ASSETS

         If within the first year of Executive's employment, the Board
determines to maximize stockholder value through disposition of a significant
amount of assets or business units of the Corporation, Executive shall assist
Corporation through such disposition and shall thereafter be entitled to
terminate this Agreement within six (6) months of such event (completion of such
disposition) and receive all benefits provided under section 6.4 hereof. As used
herein, the term ""significant amount of assets or


                                       8

<PAGE>   9

business units of the Corporation" shall mean either fifty percent (50%) or more
of the gross revenues of Corporation or, in the absence of gross revenues, 50%
of the gross assets of the Corporation including intellectual properties, as
determined by an independent appraisal, or fifty percent (50%) or more of the
operating income by excluding losses from business units of the Corporation
which are operating at a loss.)

9. BUSINESS DISCLOSURES AND SOLICITATION OF EMPLOYEES

         Executive agrees during the term of his employment by the Corporation
and thereafter that he will not disclose, other than to an authorized employee,
officer, director or agent of the Corporation, any information relating to the
Corporation's business, trade, practices, trade secrets or know-how or
proprietary information without the Corporation's prior express written consent.
Following termination of Executive's employment, Executive shall be permitted to
continue in his usual occupation and shall not be prohibited from competing with
the Corporation except during the two (2) year severance period and in the
specific industry market segments in which the Corporation competes and which
represent twenty percent (20%) or more of its revenues. Executive agrees that
for a period of one (1) year following the termination of Executive's employment
with the Corporation for any reason, Executive shall not directly or indirectly
solicit, induce, recruit or encourage any of the Corporation's employees to
leave their employment or take away such employees to leave their employment or
take away such employees or attempts to solicit, induce, recruit, encourage or
take away employees of the Corporation.

         California.

         10.9 Amendments and Waivers

              No amendment of any provision of this Agreement shall be valid

         breach of warranty or convenant hereunder, whether intentional or not,
         shall be deemed to extend to any prior or subsequent default,
         misrepresentation, or breach of warranty or convenant hereunder or
         affect in any way any rights arising by virtue of any prior or
         subsequent such occurrence.

         10.10 Severability

              Any term or provision of this Agreement that is invalid or
         unenforceable in any situation in any jurisdiction shall not affect the
         validity or enforceability of the remaining terms and provisions hereof
         or the validity or enforceability of the offending term or provision in
         any other situation or in any other jurisdiction.
