NEUROCRINE BIOSCIENCES, INC. NOTES TO THE CONDENSED FINANCIAL STATEMENTS (unaudited) 1. ORGANIZATION Neurocrine Biosciences, Inc. ("Neurocrine" or the "Company") was incorporated in California on January 17, 1992 and was reincorporated in Delaware in March 1996. In May 1998, the Company acquired Northwest NeuroLogic, Inc. ("NNL"), an Oregon-based research corporation. In December 1999, the NNL corporate structure was merged with and into the Company. Between March 1996 and December 1999, the Company owned a minority interest in Neuroscience Pharma, Inc. ("NPI"), a Canadian based research and development company. Neurocrine is a neuroscience-based company focused on the discovery and development of novel therapeutics for neuropsychiatric, neuroinflammatory and neurodegenerative diseases and disorders. The Company's neuroscience, endocrine and immunology disciplines provide a unique biological understanding of the molecular interaction between central nervous, immune and endocrine systems for the development of therapeutic interventions for anxiety, depression, insomnia, stroke, malignant brain tumors, multiple sclerosis, obesity and diabetes. 2. BASIS OF PRESENTATION The condensed financial statements included herein are unaudited. Current year financial statements include the accounts of the Company. Prior year financial statements include the Company and its wholly owned subsidiary, NNL. All significant intercompany transactions were eliminated in consolidation. The Company's minority ownership interest in NPI was accounted for under the equity method. Certain reclassifications have been made to prior year amounts to conform to the presentation for the three and six months ended June 30, 2000. The condensed financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions of the Securities and Exchange Commission ("SEC") on Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, these financial statements include all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. The results of operations for the interim periods shown in this report are not necessarily indicative of results expected for the full year. The financial statements should be read in conjunction with the audited financial statements and notes for the year ended December 31, 1999, included in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission. 3. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. 4. LOSS PER COMMON SHARE Basic net loss per common share is calculated using the weighted average number of common shares outstanding during the period. Diluted net loss per common share is calculated by adding the total incremental number of common share equivalents and the weighted average number of common shares outstanding during the period. For the periods presented, incremental shares of the common share equivalents were excluded from the calculation of diluted net loss per share as their effects were antidilutive. Page 6

5. COMPREHENSIVE INCOME Comprehensive loss for the Company consists of net loss and unrealized gains and losses on investments. The accumulated balances of these components are disclosed as a separate component of stockholders' equity. 6. NEW ACCOUNTING PRONOUNCEMENTS In December 1999, the SEC issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements". SAB 101 provides guidance in applying generally accepted accounting principles to revenue recognition in financial statements, including the recognition of nonrefundable up-front fees received in conjunction with a research and development arrangement. The Company is required to adopt the pronouncement during the fourth quarter of 2000. Management does not expect SAB 101 to have a material effect on its financial statements. In March 2000, the Financial Accounting Standards Board issued Interpretation No. 44 ("FIN 44"), "Accounting for Certain Transactions Involving Stock Compensation". This interpretation clarifies the application of Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, with respect to certain issues in accounting for employee stock compensation and is generally effective as of July 1, 2000. Management does not expect FIN 44 to have a material effect on its financial statements. Item 2: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following Management's Discussion and Analysis of Financial Condition and Results of Operations of the Company contain forward-looking statements which involve risks and uncertainties, pertaining generally to the expected continuation of the Company's collaborative agreements, the receipt of research payments thereunder, the future achievement of various milestones in product development and the receipt of payments related thereto, the potential receipt of royalty payments, pre-clinical testing and clinical trials of potential products, the period of time the Company's existing capital resources will meet its funding requirements, and financial results and operations. Actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth below and those outlined in the Company's 1999 Annual Report on Form 10-K filed with the Securities and Exchange Commission. OVERVIEW Since the founding of the Company in January 1992, Neurocrine has been engaged in the discovery and development of novel pharmaceutical products for diseases and disorders of the central nervous and immune systems. To date, Neurocrine has not generated any revenues from the sale of products, and does not expect to generate any product revenues in the foreseeable future. The Company has funded its operations primarily through public offering and payments under research and development agreements. The Company is developing a number of products with corporate collaborators and will rely on those collaborators and new collaborators to meet funding requirements. Revenues are expected to come from the Company's strategic alliances. The Company expects to generate future net losses in anticipation of significant increases in operating expenses as products are advanced through the various stages of clinical development. As of June 30, 2000, Neurocrine has incurred a cumulative deficit of $52.9 million and expects to incur operating losses in the future, which may be greater than losses in prior years. Page 7

RESULTS OF OPERATIONS THREE MONTHS ENDED JUNE 30, 2000 AND 1999 Revenues for the second quarter of 2000 were $2.9 million compared with $3.8 million for the same period last year. The decline in revenues resulted primarily from the completion of the sponsored research portion of the Eli Lilly and Company ("Lilly") Collaboration in October 1999 and the reacquisition of the Multiple Sclerosis compound in January 2000. This compound was previously licensed to Novartis in connection with a 1996 collaboration agreement. Absence of revenues from these collaborations during 2000 was partially off-set by option fees received from Taisho Pharmaceutical Co., LTD ("Taisho"). Taisho paid the Company $2.0 million for an exclusive six-month option to negotiate a collaborative agreement on the Company's altered peptide ligand for diabetes. This fee was deferred and recognized as revenue over the six-month option period. Research and development expenses increased to $8.1 million for the second quarter 2000 compared with $7.2 million for the respective period in 1999. The increase in expenses primarily reflects higher costs associated with expanding development activities, adding scientific personnel and non-cash charges associated with stock compensation for employees and consultants. General and administration expenses increased to $2.2 million for the second quarter 2000 compared with $2.0 million for the same period last year. The increase in expenses is primarily related to non-cash charges associated with stock compensation for employees and consultants. Interest income increased to $1.5 million during the second quarter of 2000 compared to $694,000 for the same period last year. The increase was primarily due to higher investment balances generated by the Company's private placement of its common stock in December 1999. This transaction generated net proceeds of $39.3 million. Net loss for the second quarter of 2000 was $5.2 million or $0.24 per share compared to $4.6 million or $0.24 per share for the same period in 1999. The increase in net loss resulted from a decline in revenues of $868,000 and an increase in operating expenses of $1.1 million, partially off-set by an increase in net interest income of $769,000. Net losses are expected to increase this year due to higher operating costs associated with the advancement of the Company's compounds through progressive clinical development. SIX MONTHS ENDED JUNE 30, 2000 AND 1999 Revenues for the six-months ended June 30, 2000 were $5.7 million compared with $7.4 million in 1999. The decline in revenues resulted primarily from the completion of the sponsored research portion of the LillyCollaboration in October 1999 and the reacquisition of the Multiple Sclerosis compound in January 2000. This compound was previously licensed to Novartis in connection with a 1996 collaboration agreement. Absence of revenues from these collaborations during 2000 was partially off-set by option fees received from Taisho. Taisho paid the Company $2.0 million for an exclusive six-month option to negotiate a collaborative agreement on the Company's altered peptide ligand for diabetes. This fee was deferred and recognized as revenue over the six-month option period. Revenues for the remainder of 2000 are expected to increase slightly over the first half of the year in connection with the Taisho collaboration signed on July 21, 2000. For the six-months ended June 30, 2000 and 1999, research and development expenses were $15.9 million and $13.6 million, respectively. The increase in expenses reflects higher costs associated with expanding development activities, adding scientific personnel and non-cash charges associated with stock compensation for employees and consultants. These expenses are expected to rise significantly over the balance of 2000 as clinical studies are expanded on current compounds and new compounds advance to the clinical development stages. Page 8

For the six-months ended June 30, 2000 and 1999, general and administrative expenditures totaled $4.4 million and $3.7 million, respectively. Business development consulting and non-cash charges associated with stock compensation for employees and consultants were primarily responsible for the increase in expenses. These expenses are expected to continue to rise over the last half of 2000. Interest income increased to $3.0 million during the six-months ended June 30, 2000 compared to $1.6 million for the same period last year. The increase was primarily due to higher investment balances generated by the Company's private placement of its common stock. The private placement was completed in December 1999 and generated net proceeds of $39.3 million. The Company anticipates interest earnings for the remainder of the 2000 to decline from quarter-to-quarter as cash reserves will be needed to fund progressive clinical trials. Net loss for the first six months of 2000 was $11.2 million or $0.51 per share compared to $8.7 million or $0.46 per share for the same period in 1999. The increase in net loss resulted from a decline in revenues of $1.6 million and an increase in operating expenses of $3.0 million, partially off-set by an increase in interest income of $1.4 million. Net losses are expected to increase this year due to higher operating costs associated with the advancement of the Company's compounds through progressive clinical development. To date, the Company's revenues have come from funded research and achievements of milestones under corporate collaborations. The nature and amount of these revenues from period to period may lead to substantial fluctuations in the results of quarterly revenues and earnings. Accordingly, results and earnings of one period are not predictive of future periods. LIQUIDITY AND CAPITAL RESOURCES At June 30, 2000, the Company's cash, cash equivalents, and short-term investments totaled $79.8 million compared with $91.1 million at December 31, 1999. The decline in cash balances during 2000 reflects the funding of progressive clinical development programs and the addition of scientific personnel. Net cash used in operating activities during the first six months of 2000 was $10.8 million compared with $8.6 million for the same period last year. The increase in net cash used resulted primarily from the funding of operating activities. The Company expects cash usage to continue during the year as clinical trial efforts are expanded. Net cash used in investing activities during the first six months of 2000 was $9.4 million compared with net cash provided of $8.6 million during the same period in 1999. The increase in cash used resulted primarily from the timing differences in the investment purchases and sales/maturities and the fluctuations in the Company's portfolio mix between cash equivalents and short-term investment holdings. The Company expects similar fluctuations to continue throughout the year. Net cash provided by financing activities during 2000 was $1.3 million compared to $233,000 during 1999. Proceeds from the issuance of common stock provided cash during 2000, while proceeds from capital leases and issuance of common stock provided cash during 1999. Management anticipates an increase in proceeds from capital leasing during the last half of 2000. The Company believes that its existing capital resources, together with interest income and future payments due under the strategic alliances, will be sufficient to satisfy its current and projected funding requirements at least for the next twelve months. However, no assurance can be given that such capital resources and payments will be sufficient to conduct its research and development programs as planned. The amount and timing of expenditures will vary depending upon a number of factors, including progress of the Company's research and development programs. Page 9

Neurocrine will require additional funding for the continuation of its research and product development programs, for progress with preclinical testing and clinical trials, for operating expenses, for the pursuit of regulatory approvals for its product candidates, for the costs involved in filing and prosecuting patent applications and enforcing or defending patent claims, if any, the cost of product in-licensing and any possible acquisitions, and may require additional funding for establishing manufacturing and marketing capabilities in the future. The Company may seek to access the public or private equity markets whenever conditions are favorable. The Company may also seek additional funding through strategic alliances and other financing mechanisms, potentially including off-balance sheet financing. There can be no assurance that adequate funding will be available on terms acceptable to the Company, if at all. If adequate funds are not available, the Company may be required to curtail significantly one or more of its research or development programs or obtain funds through arrangements with collaborative partners or others. This may require the Company to relinquish rights to certain of its technologies or product candidates. Neurocrine expects to incur operating losses over the next several years as its research, development, preclinical testing and clinical trial activities increase. To the extent that the Company is unable to obtain third party funding for such expenses, the Company expects that increased expenses will result in increased losses from operations. There can be no assurance that the Company's products under development will be successfully developed or that its products, if successfully developed, will generate revenues sufficient to enable the Company to earn a profit. INTEREST RATE RISK The Company is exposed to interest rate risk on its short-term investments and on its long-term debt. The primary objective of the Company's investment activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. To achieve this objective, the Company invests in highly liquid and high quality government and other debt securities. To minimize the exposure due to adverse shifts in interest rates, the Company invests in short-term securities with maturities of less than forty-four months. If a 10% change in interest rates were to have occurred on June 30, 2000, such a change would not have had a material effect on the fair value of the Company's investment portfolio as of that date. Due to the short holding period of the Company's investments, the Company has concluded that it does not have a material financial market risk exposure. Interest risk exposure on long-term debt relates to the Company's note payable, which bears a floating interest rate of prime plus one quarter percent (9.75% at June 30, 2000 and 8.75% at December 31, 1999). At June 30, 2000 and December 31, 1999, the note balance was $386,000 and $461,000, respectively. This note is payable in equal monthly installments through January 2003. Based on the balance of its long-term debt, the Company has concluded that it does not have a material financial market risk exposure. CAUTION ON FORWARD-LOOKING STATEMENTS The Company's business is subject to significant risks, including but not limited to, the risks inherent in its research and development activities, including the successful continuation of the Company's strategic collaborations, the successful completion of clinical trials, the lengthy, expensive and uncertain process of seeking regulatory approvals, uncertainties associated both with the potential infringement of patents and other intellectual property rights of third parties, and with obtaining and enforcing its own patents and patent rights, uncertainties regarding government reforms and of product pricing and reimbursement levels, technological change and competition, manufacturing uncertainties and dependence on third parties. Even if the Company's product candidates appear promising at an early stage of development, they may not reach the market for numerous reasons. Such reasons include the possibilities that the product will be ineffective or unsafe during clinical trials, will fail to receive necessary regulatory approvals, will be difficult to manufacture on a large scale, will be uneconomical to market or will be precluded from commercialization by proprietary rights of third parties. For a further discussion of the risks associated with an investment in the Company, please see the section entitled "Risk Factors" in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 1999.

              the year of termination based on the number of completed months of
              Executive's employment in the fiscal year plus twelve (12),
(d)           the vesting of all  outstanding  stock  options  held by Executive
              shall be  accelerated  so that the amount of shares  vested  under
              such option  shall  equal that  number of shares  which would have
              been vested if the Executive  had continued to render  services to
              the Company for twelve (12)  continuous  months  after the date of
              his termination of employment, and

         or 6.3, then this section 6.4 shall apply.

         the  understanding  that as the  Company  grows  and  management  staff

         companies,  (ii) change in reporting  relationship that does not change
         in any  material way the  Executive's  duties and  responsibilities  or
         (iii)  any   change  in  duties  or   responsibilities   or   reporting
         relationships   that  Executive  does  not  identify  as   Constructive

         following  the Chief  Executive  Officer's  proposal  of such change to
         Executive;

                  (b) a reduction  by the Company in  Executive's  annual Base
         Salary by greater  than five percent (5%);

                  (c) a  relocation  of  Executive  or the  Company's  principal
         executive  offices if Executive's  principal office is at such offices,
         to a location  more than forty  (40) miles from the  location  at which
         Executive is then  performing his duties,  except for an opportunity to
         relocate which is accepted by Executive in writing;

                  (d) any material breach by the Company of any provision of
         this Agreement; or

                  (e) any failure by the Company to obtain the  assumption  of
         this  Agreement by any  successor or assign of the Company.

termination within thirty (30) days following the six (6) month anniversary of a
Change in Control,  the  Company  shall pay to  Executive  a lump sum  severance
payment in an amount equal to one and  one-half  (1.5) times  (Executive's  then

Incentive  Plan,  as amended,  or (ii) a cash payment equal to the cash value of
all unvested  Company  stock options held by Executive at the time of the Change
in Control.  In addition,  the Executive  will be reimbursed for the increase in

provided under this Section 6.6.

appropriate that California law govern this Agreement.

         7.2 Assignment; Successors Binding Agreement.

                  (a)  Executive  may not assign,  pledge or encumber  his

         indirect,  by purchase,  merger,  consolidation or otherwise) to all or
         substantially  all of the business  and/or  assets of the  Company,  by
         operation  of law or by  agreement  in form  and  substance  reasonably
         satisfactory  to  Executive,  to  assume  and  agree  to  perform  this
         Agreement  in the same  manner and to the same  extent that the Company

of the Code,  results in the receipt by Executive on an after-tax  basis, of the
greatest amount of the payment  notwithstanding  that all or some portion of the
payment may be taxable under Section 4999 of the Code.

         goodwill of the Company's  business will be  irreparable  and extremely
         difficult  to  estimate,  making  any  remedy  at  law  or  in  damages
         inadequate.  Accordingly,  the parties  agree that the Company shall be
         entitled to  injunctive  relief  against  Executive in the event of any
         breach or threatened  breach of any such  provisions  by Executive,  in
         addition  to any  other  relief  (including  damage)  available  to the
         Company under this Agreement or under law.

                  (b) Exclusive. Both parties agree that the remedy specified in
         Section  7.9(a)  above is not  exclusive  of any other  remedy  for the
         breach by Executive of the terms hereof.

         7.10  Counterparts.  This  Agreement  may be  executed  in one or  more
counterparts,  all of which taken  together  shall  constitute  one and the same
Agreement.

         7.11  Prevailing  Party  Expenses.  In the  event  that any  action  or
proceeding is commenced to enforce the  provisions of the  Agreement,  the court
adjudicating  such action or proceeding  shall award to the prevailing party all
costs and  expenses  thereof,  including,  but not  limited  to, all  reasonable
attorneys' fees, court costs, and all other related expenses.

Executed by the parties as of the day and year first above written.

              the year of termination  based on the number of completed months
              of Executive's employment in the fiscal year plus twelve (12),
(d)           the vesting of all  outstanding  stock  options  held by Executive
              shall be  accelerated  so that the amount of shares  vested  under
              such option  shall  equal that  number of shares  which would have
              been vested if the Executive  had continued to render  services to
              the Company for twelve (12)  continuous  months  after the date of
              his termination of employment, and
(e)           the Company shall pay all costs which the Company would  otherwise
              have incurred to maintain all of  Executive's  health and welfare,
              and  retirement  benefits  (either  on the  same or  substantially
              equivalent terms and conditions) if the Executive had continued to
              render services to the Company for twelve (12)  continuous  months
              after the date of his termination of employment.

         The Company shall have no further  obligations to Executive  other than

         corporation), or (ii) hire, solicit, or attempt to solicit on behalf of
         himself or any other party or any employee or exclusive  consultant  of

         of Executive  with the Company  other than pursuant to Section 6.1, 6.2
         or 6.3, then this section 6.4 shall apply.

         not include (i) duties and responsibilities  assigned to Executive with
         the  understanding  that as the  Company  grows  and  management  staff

         companies,  (ii) change in reporting  relationship that does not change
         in any  material way the  Executive's  duties and  responsibilities  or
         (iii)  any   change  in  duties  or   responsibilities   or   reporting
         relationships   that  Executive  does  not  identify  as   Constructive

         following  the Chief  Executive  Officer's  proposal  of such change to
         Executive;

                  (b) a  reduction  by the  Company in  Executive's  annual Base
         Salary by greater than five percent (5%);

                  (c) a  relocation  of  Executive  or the  Company's  principal
         executive  offices if Executive's  principal office is at such offices,
         to a location  more than forty  (40) miles from the  location  at which
         Executive is then  performing his duties,  except for an opportunity to
         relocate which is accepted by Executive in writing;

                  (d) any  material  breach by the Company of any  provision  of
         this Agreement; or

                  (e) any  failure by the  Company to obtain the  assumption  of
         this Agreement by any successor or assign of the Company.

termination within thirty (30) days following the six (6) month anniversary of a
Change in Control,  the  Company  shall pay to  Executive  a lump sum  severance
payment in an amount equal to one (1.0) times (Executive's then Base Salary plus
annual actual cash incentive bonus for Company's  fiscal year preceding the year

(ii) a cash  payment  equal to the  cash  value of all  unvested  Company  stock
options held by Executive at the time of the Change in Control. In addition, the
Executive  will be reimbursed for the increase in federal and state income taxes
payable by Executive by reason of the benefits provided under this Section 6.6.

Executive  shall not be required to mitigate the amount of any payment  provided
under this Agreement by seeking other employment or  self-employment,  nor shall
the amount of any payment  provided  for under this  Agreement be reduced by any
compensation  earned by Executive as a result of employment by another  employer
or  through  self-employment  or  by  retirement  benefits  after  the  date  of
Executive's termination of employment from the Company.

         6.10 Coordination. If upon termination of employment, Executive becomes
entitled to rights under other plans,  contracts or arrangements entered into by
the Company, this Agreement shall be coordinated with such other arrangements so
that  Executive's  rights under this  Agreement  are not  reduced,  and that any
payments  under  this  Agreement  offset the same  types of  payments  otherwise
provided under such other arrangements, but do not otherwise reduce any payments
or benefits under such other arrangements to which Executive becomes entitled.


                                    ARTICLE 7

                               GENERAL PROVISIONS

         7.1  Governing  Law. The  validity,  interpretation,  construction  and
performance of this Agreement and the rights of the parties  thereunder shall be
interpreted and enforced under California law without reference to principles of
conflicts of laws.  The parties  expressly  agree that inasmuch as the Company's
headquarters  and principal  place of business are located in California,  it is
appropriate that California law govern this Agreement.

         7.2 Assignment; Successors Binding Agreement.

                  (a) Executive may not assign,  pledge or encumber his interest
         in this Agreement or any part thereof.

                  (b) The Company will require any successor  (whether direct or
         indirect,  by purchase,  merger,  consolidation or otherwise) to all or
         substantially  all of the business  and/or  assets of the  Company,  by
         operation  of law or by  agreement  in form  and  substance  reasonably
         satisfactory  to  Executive,  to  assume  and  agree  to  perform  this
         Agreement  in the same  manner and to the same  extent that the Company
         would be required to perform it if no such succession had taken place.

                  (c)  This  Agreement  shall  inure  to the  benefit  of and be
         enforceable   by   Executive's   personal  or  legal   representatives,
         executors, administrators, successors, heirs, distributee, devisees and
         legatees.  If  Executive  should  die while any  amount is at such time
         payable to his hereunder,  all such amounts,  unless otherwise provided
         herein, shall be paid in accordance with the terms of this Agreement to
         Executive's devisee,  legates or other designee or, if there be no such
         designee, to his estate.

         7.3 Certain  Reduction  of  Payments.  In the event that any payment or
benefit  received or to be  received by  Executive  under this  Agreement  would
result in all or a portion  of such  payment  to be subject to the excise tax on
"golden  parachute  payments" under Section 4999 of the Internal Revenue Code of
1986, as amended (the "Code"),  then Executive's payment shall be either (a) the
full  payment or (b) such lesser  amount which would result in no portion of the
payment being subject to excise tax under Section 4999 of the Code, whichever of
the foregoing  amounts,  taking into account the applicable  Federal,  state and
local employment taxes, income taxes, and the excise tax imposed by Section 4999
of the Code,  results in the receipt by Executive on an after-tax  basis, of the
greatest amount of the payment  notwithstanding  that all or some portion of the
payment may be taxable under Section 4999 of the Code.

         7.4 Notice.  For the purposes of this Agreement,  notices and all other
communications  provided for in this Agreement  shall be in writing and shall be
deemed  to have been duly  given  when  delivered  or  mailed  by  certified  or
registered mail,  return receipt  requested,  postage prepaid,  addressed to the
respective  addresses  set forth below or to such other  address as either party
may have furnished to the other in writing in accordance  herewith,  except that
notice of change of address shall be effective only upon receipt.

         To the Company:                                      To Executive:

         San Diego, CA 92121
         Attn.: President & Chief Executive Officer

         7.5  Modification;  Waiver;  Entire  Agreement.  No  provisions of this
Agreement may be modified, waived or discharged unless such waiver, modification
or discharge is agreed to in writing signed by Executive and such officer as may
be  specifically  designated  by the Board of the  Company.  No waiver by either
party  hereto at any time of any  breach by the  other  party of, or  compliance
with, any condition or provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
at the same or any prior or subsequent  time. No agreements or  representations,
oral or otherwise, express or implied, with respect to the subject matter hereof
have  been  made by  either  party  which  are not  expressly  set forth in this
Agreement.

         7.6 Validity.  The invalidity or  unenforceability  of any provision of
this  Agreement  shall not affect the  validity or  enforceability  of any other
provision of this Agreement, which shall remain in full force and effect.

         7.7  Controlling  Document.  Except to the extent  described in Section
6.l0,  in case of  conflict  between  any of the  terms  and  condition  of this
Agreement and the document  herein referred to, the terms and conditions of this
Agreement shall control.

         7.8 Executive  Acknowledgment.  Executive  acknowledges (a) that he has
consulted with or has had the opportunity to consult with independent counsel of
his own choice  concerning this Agreement,  and has been advised to do so by the
Company, and (b) that he has read and understands the Agreement,  is fully aware
of its legal effect, and has entered into it freely based on his own judgment.

         7.9 Remedies.

                  (a) Injunctive  Relief. The parties agree that the services to
         be rendered by Executive  hereunder  are of a unique nature and that in
         the event of any breach or  threatened  breach of any of the  covenants
         contained  herein,  the damage or imminent  damage to the value and the
         goodwill of the Company's  business will be  irreparable  and extremely
         difficult  to  estimate,  making  any  remedy  at  law  or  in  damages
         inadequate.  Accordingly,  the parties  agree that the Company shall be
         entitled to  injunctive  relief  against  Executive in the event of any
         breach or threatened  breach of any such  provisions  by Executive,  in
         addition  to any  other  relief  (including  damage)  available  to the
         Company under this Agreement or under law.

                  (b) Exclusive. Both parties agree that the remedy specified in
         Section  7.9(a)  above is not  exclusive  of any other  remedy  for the
         breach by Executive of the terms hereof.

         7.10  Counterparts.  This  Agreement  may be  executed  in one or  more
counterparts,  all of which taken  together  shall  constitute  one and the same
Agreement.

         7.11  Prevailing  Party  Expenses.  In the  event  that any  action  or
proceeding is commenced to enforce the  provisions of the  Agreement,  the court
adjudicating  such action or proceeding  shall award to the prevailing party all
costs and  expenses  thereof,  including,  but not  limited  to, all  reasonable
attorneys' fees, court costs, and all other related expenses.

Executed by the parties as of the day and year first above written.

provide Executive with the usual health insurance benefits it generally provides
to its other  senior  management  employees.  As Executive  becomes  eligible in
accordance with criteria to be adopted by the Company, the Company shall provide

as such plans and benefits may be adopted by the Company.  The amount and extent

         4.3 Housing and Relocation Allowances.

         (a) Relocation to the Untied Kingdom.  Upon  termination of Executive's
         employment  with the  Company,  the  Company  has  agreed to  reimburse
         Executive  for costs  associated  with  relocation  back to the  United
         Kingdom  including (i) customary  closing costs and fees (not to exceed
         six  percent  (6%)  of  the  selling  price)  related  to the  sale  of
         Executive's  home in San  Diego  and  (ii)  documented  reasonable  and
         customary moving expenses of household goods and personal  property not
         to  exceed  in  the  aggregate  ten  thousand  dollars  ($10,000).  The
         foregoing provision shall not apply in the event (each a "Disqualifying
         Event")  (i)  at  the  time  of  relocation,   Executive  has  accepted
         employment with another company or it is Executive's intention to do so
         within a period of six (6) months,  (ii)  Executive  has not  completed
         four (4) full years of employment  at the Company or (iii)  termination
         of Executive's  employment  with the Company is for Cause as defined in
         paragraph 6.3 below. In 1999 Executive  elected to sell his home in San
         Diego  and  in  connection  therewith  incurred  seventy-five  thousand
         dollars ($75,000) in documented closing costs. In connection therewith,
         the Company  provided to  Executive,  a loan of  seventy-five  thousand
         dollars  ($75,000) (the  "Relocation  Loan") for the costs that will be
         paid by Company on behalf of Executive hereunder in the event Executive
         meets the requirements for such payments.  The principal balance of the
         Relocation  Loan will bear  interest at a rate of one percent per annum
         (1.0% p.a.) and  principal and interest will be due and payable in full
         upon the earlier of (i) an  Disqualifying  Event or (ii) the  exercise,
         pledge or sale of all or part of the stock  options  granted by Company
         to Executive.  Upon  termination  of  Executive's  employment  with the
         Company  at a time  when  no  Disqualifying  Event  has  occurred,  the
         principal  of the  Relocation  Loan will,  together  with any  interest
         accruing on such amount, be forgiven.

         (b) Travel Allowance. The Company will provide to Executive annually up
         to four (4) round trip Coach Class  airline  tickets San Diego-  United
         Kingdom for  Executive  and his family.  These  tickets  will be booked
         through the  Company's  corporate  travel  account and the Company will
         provide  Business  Class  upgrades  for such tickets on an as available
         basis.

         (c) Taxes. Executive will be responsible for the payment of all federal
         and state income taxes on all  allowances,  loans and loan  forgiveness
         accruing to Executive pursuant to this Section 4.3.

         4.4 Business Expense Reimbursement.  During the term of this Agreement,
Executive shall be entitled to receive proper  reimbursement  for all reasonable
out-of-pocket  expenses  incurred by him (in  accordance  with the  policies and
procedures  established  by the Company for its senior  executive  officers)  in
performing  services  hereunder.  Executive  agrees to  furnish  to the  Company
adequate  records  and other  documentary  evidence  of such  expense  for which
Executive seeks  reimbursement.  Such expenses shall be reimbursed and accounted
for under the policies and procedure established by the Company.

                                    ARTICLE 5

                                 CONFIDENTIALITY

         5.1 Proprietary Information.  Executive represents and warrants that he
has  previously  executed and  delivered to the Company the  Company's  standard
Proprietary  Information  and  Inventions  Agreement in form  acceptable  to the
Company's counsel.

         5.2 Return of Property. All documents,  records,  apparatus,  equipment
and other  physical  property  which is furnished to or obtained by Executive in
the  course of his  employment  with the  Company  shall be and  remain the sole
property of the Company.  Executive  agrees that,  upon the  termination  of his
employment,  he shall  return all such  property  (whether or not it pertains to
Proprietary Information as defined in the Proprietary Information and Inventions
Agreement), and agrees not to make or retain copies,  reproductions or summaries
of any such property.

         5.3      No use of Prior Confidential Information.  Executive will not
intentionally disclose to the Company or use on its behalf any confidential
information belonging to any of his former employers or any other third party.


                                    ARTICLE 6

                                   TERMINATION

         6.1 By Death.  The period of employment  shall terminate  automatically
upon the death of Executive.  In such event, all stock options held by Executive
at the time of termination  will continue to vest for a period of six (6) months
following  termination.  All stock options held by Executive which are vested at
the time of termination or within six (6) months  thereafter will be exercisable
in accordance  with their terms for a period of one year following  termination.
In addition,  the Company shall pay to Executive's  beneficiaries or his estate,
as the case may be, any  accrued  Base  Salary,  any bonus  compensation  to the
extent  earned,  any vested  deferred  compensation  (other than pension plan or

applicable plan), any benefits under any plans of the Company in which Executive
is a participant to the full extent of Executive's  rights under such plans, any
accrued vacation pay and any appropriate business expenses incurred by Executive
in  connection  with  his  duties  hereunder,  all to the  date  of  termination
(collectively Accrued Compensation),  but no other compensation or reimbursement
of  any  kind,  including,  without  limitation,   severance  compensation,  and
thereafter, the Company's obligations hereunder shall terminate.

         6.2 By Disability.  If Executive is prevented from properly  performing
his duties hereunder by reason of any physical or mental incapacity for a period
of one hundred and twenty (120)  consecutive days, or for one hundred and eighty
(180)  days in the  aggregate  in any three  hundred  and  sixty-five  (365) day
period,  then,  to the extent  permitted by law, the Company may  terminate  the
employment of Executive at such time.  In such event,  all stock options held by
Executive  will  continue  to vest  for a  period  of six (6)  months  following
termination.  All stock options  vested at the time of termination or within six
(6) months  thereafter  will be exercisable in accordance with their terms for a
period of one year following termination.  In addition, the Company shall pay to
Executive all Accrued  Compensation,  and shall continue to pay to Executive the
Base  Salary  until such time as  Executive  shall  become  entitled  to receive
disability insurance payments under the disability insurance policy


maintained by the Company,  but no other  compensation or  reimbursement  of any
kind, including without limitation,  severance compensation,  and thereafter the
Company's obligations  hereunder shall terminate.  Nothing in this Section shall

employment for Cause (as defined  below)  without  liability at any time with or
without advance notice to Executive. The Company shall pay Executive all Accrued
Compensation,  but no other compensation or reimbursement of any kind, including
without  limitation,   severance  compensation,  and  thereafter  the  Company's
obligations  hereunder shall terminate.  Termination shall be for "Cause" in the
event of the occurrence of any of the following:  (a) any intentional  action or
intentional  failure to act by Executive which was performed in bad faith and to
the material detriment of the Company;  (b) Executive  intentionally  refuses or
intentionally fails to act in accordance with any lawful and proper direction or
order of the Chief  Executive  Officer;  (c) Executive  habitually  neglects the
duties of employment;  or (d) Executive is convicted of a felony crime involving
moral  turpitude,  provided that in the event that an of the foregoing events is
capable of being cured,  the Company shall provide  written  notice to Executive
describing the nature of such event and Executive shall thereafter have ten (10)
business days to cure such event.

         6.4  Termination  Without Cause. At any time, the Company may terminate
the employment of Executive without liability other than as set forth below, for
any reason not  specified  in Section  6.3  above,  by giving  thirty  (30) days
advance  written  notice  to  Executive.  If the  Company  elects  to  terminate
Executive pursuant to this Section 6.4,

(a)      the Company shall pay to Executive all Accrued Compensation,
(b)           the Company shall continue to pay to Executive as provided  herein
              Executive's  Base Salary over the period  equal to nine (9) months
              from the date of such termination as severance compensation,
(c)           the  Company  shall  make a lump sum  payment to  Executive  in an

              actual cash  incentive  bonus for Company's  fiscal year preceding
              the year of termination based on the number of completed months of
              Executive's employment in the fiscal year plus nine (9),
(d)           the vesting of all  outstanding  stock  options  held by Executive
              shall be  accelerated  so that the amount of shares  vested  under
              such option  shall  equal that  number of shares  which would have
              been vested if the Executive  had continued to render  services to
              the Company for nine (9)  continuous  months after the date of his
              termination of employment, and
(e)           the Company shall pay all costs which the Company would  otherwise
              have incurred to maintain all of  Executive's  health and welfare,
              and  retirement  benefits  (either  on the  same or  substantially
              equivalent terms and conditions) if the Executive had continued to
              render  services  to the Company  for nine (9)  continuous  months
              after the date of his termination of employment.

         The Company shall have no further  obligations to Executive  other than
         those set forth in the preceding sentence.  During the period when such
         severance compensation is being paid to Executive,  Executive shall not
         (i) engage, directly or indirectly,  in providing services to any other
         business program or project that is competitive to a program or project

         terminates  this  Agreement or the  employment  of  Executive  with the

termination  of  his  employment  for  death,  disability,   retirement,  fraud,
misappropriation,  embezzlement  (or  any  other  occurrence  which  constitutes
"Cause" under section 6.3) or any other  voluntary  termination of employment by

         Executive's position in the Company's peer group of companies and shall
         not include (i) duties and responsibilities  assigned to Executive with
         the  understanding  that as the  Company  grows  and  management  staff
         increases in number, such duties and  responsibilities  will eventually
         be reassigned in a manner  consistent  with the Company's peer group of
         companies,  (ii) change in reporting  relationship that does not change
         in any  material way the  Executive's  duties and  responsibilities  or
         (iii)  any   change  in  duties  or   responsibilities   or   reporting
         relationships   that  Executive  does  not  identify  as   Constructive

         following  the Chief  Executive  Officer's  proposal  of such change to
         Executive;

         Salary by greater than five percent (5%);

                  (c) a  relocation  of  Executive  or the  Company's  principal
         executive  offices if Executive's  principal office is at such offices,
         to a location  more than forty  (40) miles from the  location  at which
         Executive is then  performing his duties,  except for an opportunity to
         relocate which is accepted by Executive in writing;

                  (d) any  material  breach by the Company of any  provision  of
         this Agreement; or

                  (e) any  failure by the  Company to obtain the  assumption  of
         this Agreement by any successor or assign of the Company.

termination within thirty (30) days following the six (6) month anniversary of a

         7.1  Governing  Law. The  validity,  interpretation,  construction  and
performance of this Agreement and the rights of the parties  thereunder shall be

headquarters  and principal  place of business are located in California,  it is
appropriate that California law govern this Agreement.

         7.2 Assignment; Successors Binding Agreement.

                  (a) Executive may not assign,  pledge or encumber his interest
         in this Agreement or any part

                  (b) The Company will require any successor  (whether direct or
         indirect,  by purchase,  merger,  consolidation or otherwise) to all or
         substantially  all of the business  and/or  assets of the  Company,  by
         operation  of law or by  agreement  in form  and  substance  reasonably
         satisfactory  to  Executive,  to  assume  and  agree  to  perform  this
         Agreement  in the same  manner and to the same  extent that the Company
         would be required to perform it if no such succession had taken place.

                  (c)  This  Agreement  shall  inure  to the  benefit  of and be
         enforceable   by   Executive's   personal  or  legal   representatives,

         legatees.  If  Executive  should  die while any  amount is at such time
         payable to his hereunder,  all such amounts,  unless otherwise provided

result in all or a portion  of such  payment  to be subject to the excise tax on
"golden  parachute  payments" under Section 4999 of the Internal Revenue Code of
1986, as amended (the "Code"),  then Executive's payment shall be either (a) the
full  payment or (b) such lesser  amount which would result in no portion of the
payment being subject to excise tax under Section 4999 of the Code, whichever of
the foregoing  amounts,  taking into account the applicable  Federal,  state and
local employment taxes, income taxes, and the excise tax imposed by Section 4999
of the Code,  results in the receipt by Executive on an after-tax  basis, of the
greatest amount of the payment  notwithstanding  that all or some portion of the
payment may be taxable under Section 4999 of the Code.


         7.4 Notice.  For the purposes of this Agreement,  notices and all other

Agreement may be modified, waived or discharged unless such waiver, modification
or discharge is agreed to in writing signed by Executive and such officer as may
be  specifically  designated  by the Board of the  Company.  No waiver by either
party  hereto at any time of any  breach by the  other  party of, or  compliance
with, any condition or provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
at the same or any prior or subsequent  time. No agreements or  representations,
oral or otherwise, express or implied, with respect to the subject matter hereof
have  been  made by  either  party  which  are not  expressly  set forth in this
Agreement.

         7.6 Validity.  The invalidity or  unenforceability  of any provision of

         goodwill of the Company's  business will be  irreparable  and extremely
         difficult  to  estimate,  making  any  remedy  at  law  or  in  damages
         inadequate.  Accordingly,  the parties  agree that the Company shall be
         entitled to  injunctive  relief  against  Executive in the event of any
         breach or threatened  breach of any such  provisions  by Executive,  in
         addition  to any  other  relief  (including  damage)  available  to the

         breach by Executive of the terms hereof.

counterparts,  all of which taken  together  shall  constitute  one and the same
Agreement.

adjudicating  such action or proceeding  shall award to the prevailing party all
costs and  expenses  thereof,  including,  but not  limited  to, all  reasonable
attorneys' fees, court costs, and all other related expenses.

         6.1 By Death.  The period of employment  shall terminate  automatically
upon the death of Executive.  In such event, all stock options held by Executive
at the time of termination  will continue to vest for a period of six (6) months
following  termination.  All stock options held by Executive  that are vested at
the time of termination or within six (6) months  thereafter will be exercisable
in accordance  with their terms for a period of one year following  termination.
In addition,  the Company shall pay to Executive's  beneficiaries or her estate,
as the case may be, any  accrued  Base  Salary,  any bonus  compensation  to the
extent  earned,  any vested  deferred  compensation  (other than pension plan or
profit-sharing  plan  benefits  which  will  be  paid  in  accordance  with  the
applicable plan), any benefits under any plans of the Company in which Executive
is a participant to the full extent of Executive's  rights under such plans, any
accrued vacation pay and any appropriate business expenses incurred by Executive
in  connection  with  her  duties  hereunder,  all to the  date  of  termination
(collectively Accrued Compensation),  but no other compensation or reimbursement
of  any  kind,  including,  without  limitation,   severance  compensation,  and
thereafter, the Company's obligations hereunder shall terminate.

         6.2 By Disability.  If Executive is prevented from properly  performing
her duties hereunder by reason of any physical or mental incapacity for a period
of one hundred  twenty (120)  consecutive  days, or for one hundred eighty (180)
days in the aggregate in any three hundred sixty-five (365) day period, then, to
the extent  permitted  by law,  the  Company may  terminate  the  employment  of
Executive at such time.  In such event,  all stock  options held by Executive at
the time of  termination  will  continue  to vest for a period of six (6) months
following  termination.  All stock options held by Executive  that are vested at
the  time of  termination  or vest  within  six (6)  months  thereafter  will be
exercisable  in accordance  with their terms for a period of one year  following
termination.  In  addition,  the  Company  shall pay to  Executive  all  Accrued
Compensation,  and shall continue to pay to Executive the Base Salary until such
time as Executive shall become entitled to receive disability insurance payments
under the disability  insurance policy  maintained by the Company,  but no other
compensation  or  reimbursement  of  any  kind,  including  without  limitation,
severance compensation, and thereafter the Company's obligations hereunder shall
terminate.  Nothing in this Section  shall affect  Executive's  rights under any
disability plan in which she is a participant.

         6.3 By Company for Cause.  The Company may  terminate  the  Executive's
employment for Cause (as defined  below)  without  liability at any time with or
without advance notice to Executive. The Company shall pay Executive all Accrued
Compensation,  but no other compensation or reimbursement of any kind, including
without  limitation,   severance  compensation,  and  thereafter  the  Company's
obligations  hereunder shall terminate.  Termination shall be for "Cause" in the
event of the occurrence of any of the following:  (a) any intentional  action or
intentional  failure to act by Executive which was performed in bad faith and to
the material detriment of the Company;  (b) Executive  intentionally  refuses or
intentionally fails to act in accordance with any lawful and proper direction or
order of the Chief  Executive  Officer;  (c) Executive  habitually  neglects the
duties of employment;  or (d) Executive is convicted of a felony crime involving
moral  turpitude,  provided that in the event that an of the foregoing events is
capable of being cured,  the Company shall provide  written  notice to Executive
describing the nature of such event and Executive shall thereafter have ten (10)
business days to cure such event.

         6.4  Termination  Without Cause. At any time, the Company may terminate
the employment of Executive without liability other than as set forth below, for
any reason not  specified  in Section  6.3  above,  by giving  thirty  (30) days
advance  written  notice  to  Executive.  If the  Company  elects  to  terminate
Executive pursuant to this Section 6.4,

(a)           the Company shall pay to Executive all Accrued Compensation,
(b)           the Company shall continue to pay to Executive as provided  herein
              Executive's  Base Salary over the period  equal to nine (9) months
              from the date of such termination as severance compensation,
(c)           the  Company  shall  make a lump sum  payment to  Executive  in an
              amount  equal  to a pro rata  portion  of the  Executive's  annual
              actual cash  incentive  bonus for Company's  fiscal year preceding
              the year of termination based on the number of completed months of
              Executive's employment in the fiscal year plus nine (9),
(d)           the vesting of all  outstanding  stock  options  held by Executive
              shall be  accelerated  so that the amount of shares  vested  under
              such option  shall  equal that  number of shares  which would have
              been vested if the Executive  had continued to render  services to
              the Company for nine (9)  continuous  months after the date of her
              termination of employment, and
(e)           the Company shall pay all costs which the Company would  otherwise
              have incurred to maintain all of  Executive's  health and welfare,
              and  retirement  benefits  (either  on the  same or  substantially
              equivalent terms and conditions) if the Executive had continued to
              render  services  to the Company  for nine (9)  continuous  months
              after the date of her termination of employment.

         The Company shall have no further  obligations to Executive  other than
         those set forth in the preceding sentence.  During the period when such
         severance compensation is being paid to Executive,  Executive shall not
         (i) engage, directly or indirectly,  in providing services to any other
         business program or project that is competitive to a program or project
         being conducted by the Company or any Affiliated Company at the time of
         such employment  termination (provided that Executive may own less than
         two percent (2%) of the  outstanding  securities of any publicly traded
         corporation), or (ii) hire, solicit, or attempt to solicit on behalf of
         himself or any other party or any employee or exclusive  consultant  of
         the Company. If the Company terminates this Agreement or the employment
         of Executive  with the Company  other than pursuant to Section 6.1, 6.2
         or 6.3, then this section 6.4 shall apply.

         6.5 Constructive Termination A Constructive Termination shall be deemed
to be a termination of employment of Executive without cause pursuant to Section
6.4. For Purposes of this Agreement, a "Constructive Termination" means that the
Executive  voluntarily  terminates his employment  except in connection with the
termination  of  her  employment  for  death,  disability,   retirement,  fraud,
misappropriation,  embezzlement  (or  any  other  occurrence  which  constitutes
"Cause" under section 6.3) or any other  voluntary  termination of employment by
Executive other than a Constructive  Termination  after any of the following are
undertaken without Executive's express written consent:

                  (a)  the   assignment   to   Executive   of  any   duties   or
         responsibilities  which result in any  diminution of position as judged

         Executive's position in the Company's peer group of companies and shall
         not include (i) duties and responsibilities  assigned to Executive with
         the  understanding  that as the  Company  grows  and  management  staff
         increases in number, such duties and  responsibilities  will eventually
         be reassigned in a manner  consistent  with the Company's peer group of
         companies,  (ii) change in reporting  relationship that does not change
         in any  material way the  Executive's  duties and  responsibilities  or
         (iii)  any   change  in  duties  or   responsibilities   or   reporting
         relationships   that  Executive  does  not  identify  as   Constructive
         Termination  to the Chief  Executive  Officer in writing within 15 days
         following  the Chief  Executive  Officer's  proposal  of such change to
         Executive;
                   (b) a  reduction  by the  Company in  Executive's annual Base
         Salary by greater than five percent (5%);
                   (c) a relocation of Executive or the Company's principal
         executive  offices if Executive's  principal office is at such offices,
         to a location  more than forty  (40) miles from the  location  at which
         Executive is then  performing her duties,  except for an opportunity to
         relocate which is accepted by Executive in writing;
                  (d) any  material  breach by the Company of any  provision  of
         this Agreement; or
                  (e) any  failure by the  Company to obtain the  assumption  of
         this Agreement by any successor or assign of the Company.

         6.6  Termination  Following  Change  in  Control.  In  the  event  of a
termination  Without  Cause or  Constructive  Termination  within six (6) months
after  a  Change  in  Control  (as  defined  below)  or  Executive's   voluntary
termination within thirty (30) days following the six (6) month anniversary of a
Change in Control,  the  Company  shall pay to  Executive  a lump sum  severance
payment in an amount equal to one (1.0) times (Executive's then Base Salary plus
annual actual cash incentive bonus for Company's  fiscal year preceding the year
of termination).  In addition,  the Executive will receive at Executive's option
(i) accelerated  vesting of all stock options held by Executive by reason of the
assumption  or  substitution  of  successor  corporation  stock  options for the
Executive's  unvested Company stock options at the time of the Change in Control
pursuant to the terms of the Company's 1992 Stock Incentive Plan, as amended, or
(ii) a cash  payment  equal to the  cash  value of all  unvested  Company  stock
options held by Executive at the time of the Change in Control. In addition, the
Executive  will be reimbursed for the increase in federal and state income taxes
payable by Executive by reason of the benefits provided under this Section 6.6.

         6.7 Change in Control.  For  purposes of this  Agreement,  a "Change in
Control"  shall have  occurred  if at any time  during  the term of  Executive's
employment hereunder, any of the following events shall occur:

         combined  voting  power  of the  then-outstanding  securities  of  such
         corporation or person  immediately  after such  transaction are held in

         immediately prior to such transaction;
                  (b) The Company sells all or  substantially  all of its assets
         or any other  corporation  or other legal person and  thereafter,  less
         than 50% of the combined  voting power of the  then-outstanding  voting
         securities  of the  acquiring  or  consolidated  entity are held in the
         aggregate  by  the  holders  of  voting   securities   of  the  Company
         immediately prior to such sale;
                  (c) There is a report  filed after the date of this  Agreement

         exchange Act) has become the beneficial  owner (as the term  beneficial
         owner is defined under Rule 13d-3 or any  successor  rule or regulation
         promulgated  under the Exchange  Act)  representing  50% or more of the
         combined voting power of the then-outstanding  voting securities of the
         Company;
                  (d) The Company  shall file a report or proxy  statement  with
         the  Securities  and Exchange  Commission  pursuant to the Exchange Act
         disclosing in response to item 1 of Form 8-X thereunder or Item 5(f) of
         Schedule 14 A thereunder (or any successor schedule,  form or report or
         item therein) that the change in control of the Company has or may have
         occurred  or  will  or  may  occur  in  the  future   pursuant  to  any
         then-existing contract or transaction; or
                  (e)  During  any   period  of  two  (2)   consecutive   years,
         individuals  who at the  beginning  of any such period  constitute  the
         directors of the Company  cease for any reason to constitute at least a

employment by giving thirty (30) days advance written notice to the Company. The
Company shall pay Executive all Accrued Compensation,  but no other compensation

Executive  shall not be required to mitigate the amount of any payment  provided
under this Agreement by seeking other employment or  self-employment,  nor shall
the amount of any payment  provided  for under this  Agreement be reduced by any
compensation  earned by Executive as a result of employment by another  employer
or  through  self-employment  or  by  retirement  benefits  after  the  date  of
Executive's termination of employment from the Company.

payments  under  this  Agreement  offset the same  types of  payments  otherwise
provided under such other arrangements, but do not otherwise reduce any payments
or benefits under such other arrangements to which Executive becomes entitled.


                                    ARTICLE 7

                               GENERAL PROVISIONS

         7.1  Governing  Law. The  validity,  interpretation,  construction  and
performance of this Agreement and the rights of the parties  thereunder shall be
interpreted and enforced under California law without reference to principles of
conflicts of laws.  The parties  expressly  agree that inasmuch as the Company's
headquarters  and principal  place of business are located in California,  it is
appropriate that California law govern this Agreement.

         7.2 Assignment; Successors Binding Agreement.

                  (a) Executive may not assign,  pledge or encumber her interest
         in this Agreement or any part thereof.
                  (b) The Company will require any successor  (whether direct or
         indirect,  by purchase,  merger,  consolidation or otherwise) to all or
         substantially  all of the business  and/or  assets of the  Company,  by
         operation  of law or by  agreement  in form  and  substance  reasonably
         satisfactory  to  Executive,  to  assume  and  agree  to  perform  this
         Agreement  in the same  manner and to the same  extent that the Company
         would be required to perform it if no such succession had taken place.
                  (c)  This  Agreement  shall  inure  to the  benefit  of and be
         enforceable   by   Executive's   personal  or  legal   representatives,
         executors, administrators, successors, heirs, distributee, devisees and
         legatees.  If  Executive  should  die while any  amount is at such time
         payable to her hereunder,  all such amounts,  unless otherwise provided
         herein, shall be paid in accordance with the terms of this Agreement to
         Executive's devisee,  legates or other designee or, if there be no such
         designee, to her estate.

         7.3 Certain  Reduction  of  Payments.  In the event that any payment or
benefit  received or to be  received by  Executive  under this  Agreement  would
result in all or a portion  of such  payment  to be subject to the excise tax on
"golden  parachute  payments" under Section 4999 of the Internal Revenue Code of
1986, as amended (the "Code"),  then Executive's payment shall be either (a) the
full  payment or (b) such lesser  amount which would result in no portion of the
payment being subject to excise tax under Section 4999 of the Code, whichever of
the foregoing  amounts,  taking into account the applicable  Federal,  state and
local employment taxes, income taxes, and the excise tax imposed by Section 4999
of the Code,  results in the receipt by Executive on an after-tax  basis, of the
greatest amount of the payment  notwithstanding  that all or some portion of the
payment may be taxable under Section 4999 of the Code.

         7.4 Notice.  For the purposes of this Agreement,  notices and all other
communications  provided for in this Agreement  shall be in writing and shall be
deemed  to have been duly  given  when  delivered  or  mailed  by  certified  or
registered mail,  return receipt  requested,  postage prepaid,  addressed to the
respective  addresses  set forth below or to such other  address as either party
may have furnished to the other in writing in accordance  herewith,  except that

 To Executive:
         Margaret Valeur-Jensen, Ph.D., J.D.

         7.5  Modification;  Waiver;  Entire  Agreement.  No  provisions of this
Agreement may be modified, waived or discharged unless such waiver, modification
or discharge is agreed to in writing signed by Executive and such officer as may
be  specifically  designated  by the Board of the  Company.  No waiver by either
party  hereto at any time of any  breach by the  other  party of, or  compliance
with, any condition or provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
at the same or any prior or subsequent  time. No agreements or  representations,
oral or otherwise, express or implied, with respect to the subject matter hereof
have  been  made by  either  party  which  are not  expressly  set forth in this
Agreement.

         7.6 Validity.  The invalidity or  unenforceability  of any provision of
this  Agreement  shall not affect the  validity or  enforceability  of any other
provision of this Agreement, which shall remain in full force and effect.

         7.7  Controlling  Document.  Except to the extent  described in Section
6.l0,  in case of  conflict  between  any of the  terms  and  condition  of this
Agreement and the document  herein referred to, the terms and conditions of this
Agreement shall control.

         7.8 Executive  Acknowledgment.  Executive acknowledges (a) that she has
consulted with or has had the opportunity to consult with independent counsel of
her own choice  concerning this Agreement,  and has been advised to do so by the
Company, and (b) that she has read and understands the Agreement, is fully aware
of its legal effect, and has entered into it freely based on her own judgment.

         7.9 Remedies.

                  (a) Injunctive  Relief. The parties agree that the services to
         be rendered by Executive  hereunder  are of a unique nature and that in
         the event of any breach or  threatened  breach of any of the  covenants
         contained  herein,  the damage or imminent  damage to the value and the
         goodwill of the Company's  business will be  irreparable  and extremely
         difficult  to  estimate,  making  any  remedy  at  law  or  in  damages
         inadequate.  Accordingly,  the parties  agree that the Company shall be
         entitled to  injunctive  relief  against  Executive in the event of any
         breach or threatened  breach of any such  provisions  by Executive,  in
         addition  to any  other  relief  (including  damage)  available  to the
         Company under this Agreement or under law.

                  (b) Exclusive. Both parties agree that the remedy specified in
         Section  7.9(a)  above is not  exclusive  of any other  remedy  for the
         breach by Executive of the terms hereof.

         7.10  Counterparts.  This  Agreement  may be  executed  in one or  more
counterparts,  all of which taken  together  shall  constitute  one and the same
Agreement.

         7.11  Prevailing  Party  Expenses.  In the  event  that any  action  or
proceeding is commenced to enforce the  provisions of the  Agreement,  the court
adjudicating  such action or proceeding  shall award to the prevailing party all
costs and  expenses  thereof,  including,  but not  limited  to, all  reasonable
attorneys' fees, court costs, and all other related expenses.

Executed by the parties as of the day and year first above written.
