of the Company; or
<PAGE>

               (iii) invest in or become a shareholder of another corporation or
other entity; provided, that the Employee's investment solely as a shareholder

national securities exchange.

          (c) Prior to or concurrently with the execution of this Agreement, the
Employee has executed an Employee Proprietary Information, Trade Secret and
Confidentiality Agreement (the "Confidentiality Agreement").

the Employee shall be employed for less than the entire number of days in such
month, the compensation payable under this Section 3(a) shall be prorated on the
basis of the number of days during which the Employee was actually employed
divided by the number of days in such month.

          (b) The Base Salary is a gross amount, and the Company shall be
required to withhold from such amount deductions with respect to Federal, state
and local taxes, FICA, unemployment compensation taxes and similar taxes,
assessments or withholding requirements.

          (c) During the Employee's employment under this Agreement, the
Employee shall also be reimbursed by the Company for reasonable business
expenses actually incurred or paid by the Employee, consistent with the policies
established by the Board, in rendering to the Company the services provided for
in this Agreement, upon presentation of expense statements or such other
supporting information as is consistent with the policies of the Company.

          (d) The Employee shall be entitled to 20 business days vacation for
each full year of employment under this Agreement, which vacation time will
accrue in accordance with the vacation policy of the Company.

(including deferred compensation plans and any medical, dental or life insurance
plans) which shall
<PAGE>

be available from time to time to the domestic management employees of the
Company generally, except to the extent such participation in any plan would, in
the opinion of the Designated Officer, alter the intended tax treatment of such
plan; provided, however, that the Employee shall have no right under this
Agreement to participate in any stock option, stock purchase or other plan
relating to shares of capital stock of the Company or its affiliates. The
Employee acknowledges and agrees that the Board may in its discretion terminate
at any time or modify from time to time any such benefit plans.

benefits except to the extent provided by the Board.

     4. Termination.

Employee remains employed by the Company, unless such at-will employment
relationship is modified by a specific, express written agreement signed by the
Company.

          (f) If the Employee's employment is terminated pursuant to this

          (g) Employee may terminate his employment hereunder for "Good Reason"
(as hereinafter defined).

               (i) For purposes of this Agreement, "Good Reason" shall mean a

defined): (i) a reduction in Employee's Base Salary then in effect; (ii) a

those described in Section 1(a) of this Agreement; or (iii) the failure of the
Company to obtain the assumption of this Agreement by any successor to the
extent required pursuant to Section 10(a) of this Agreement.

               (ii) For purposes of this Agreement, the term "Change in Control"
shall mean the occurrence of any of the following events with respect to the
Company:
<PAGE>

                    (A) All or substantially all of the assets of the Company
are sold or transferred to another corporation or entity; or

                    (B) The Company is sold, transferred, merged, consolidated,
ventured or reorganized into or with another corporation or entity, with the
result that upon conclusion of the transaction less than a majority of the
outstanding securities entitled to vote generally in the election of directors
or other capital interests of the acquiring corporation or entity are owned,
directly or indirectly, by the shareholders of the Company immediately prior to
the sale, transfer, merger, consolidation, venture or reorganization; or

                    (C) There is a report filed on Schedule 13D or Schedule
14D-1 (or any successor schedule, form or report), each as promulgated pursuant
to the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
disclosing that any person (as the term "person" is used in Section 13(d)(3) or
Section 14(d)(2) of the 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) of securities representing more
than 50% of the combined voting power of the then-outstanding voting securities
of the Company; or

                    (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-K thereunder or Item 14 of Schedule 14A
thereunder (or any successor schedule, form or report or item therein) that a
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) The individuals who, at the beginning of any period of
two consecutive calendar years, constituted members of the Board cease for any
reason to constitute at least a majority thereof unless the nomination for
election by the Company's stockholders of each new director of the Company was
approved by a vote of at least two-thirds of the directors of the Company still
in office who were Directors of the Company at the beginning of any such period.

               (iii) Notwithstanding the foregoing, a termination shall not be
treated as a termination for Good Reason (i) if Employee shall have specifically
consented in writing to the occurrence of the event giving rise to the claim of
termination for Good Reason or (ii) unless Employee, within 30 days after
receiving written notice from the Company specifying in reasonable detail the
occurrence of one of such events, shall have delivered a written notice to the
Company stating that he intends to terminate his employment for Good Reason and
specifying the factual basis for such termination and such event, if capable of
being cured, shall not have been cured within 30 days of the receipt by the
Company of such notice.
<PAGE>

               (iv) If Employee shall terminate his employment for Good Reason,
the Company shall pay Employee (or, in the event of his death, his devisee,
legatee or, if there is none, his estate) a lump-sum amount equal to the highest
level of Employee's annual Base Salary in effect on the date of the Change in
Control, multiplied by a factor of 2.0. Employee will also be entitled to any
vested benefits under any employee benefit plans.

     5. Employee's Representations.

          (a) The Employee represents that he has full authority to enter into

Company, its officers, directors and stockholders from and against any losses,
liabilities, damages or costs (including reasonable attorney's fees) arising out
of a breach, or claimed breach, of any of the representations, warranties and
covenants of the Employee set forth in this Agreement.

          (c) The Employee acknowledges that he is free to seek advice from
independent counsel with respect to this Agreement. The Employee has either

advice from the Company or any of its officers, directors, attorneys or other
representatives regarding this Agreement, its content or effect.

     6. Arbitration. Any controversy or claim arising out of or relating to this
Agreement or any breach hereof or the Employee's employment by the Company or
termination thereof, shall be settled by arbitration by one arbitrator in
accordance with the rules of the American Arbitration Association, and judgment
upon such award rendered by the arbitrator may be entered in any court having
jurisdiction thereof. The arbitration shall be held in the City of San Diego or
such other place as may be agreed upon at the time by the parties to the
arbitration.

     7. Equitable Relief. The Employee acknowledges that the Company is relying
for its protection upon the existence and validity of the provisions of this
Agreement, that the services to be rendered by the Employee are of a special,
unique and extraordinary character, and that irreparable injury will result to
the Company from any violation or continuing violation of the provisions of this
Agreement for which damages may not be an adequate remedy. Accordingly, the
Employee hereby agrees that in addition to the remedies available to the Company
by law or under this Agreement, the Company shall be entitled to obtain such
equitable relief as may be permitted by law in a court of competent jurisdiction
including, without limitation, injunctive relief from any violation or
continuing violation by the Employee of any term or provision of this Agreement.

     8. Governing Law. This Agreement shall be governed by and construed and
enforced in accordance with the internal substantive laws (and not the laws of
conflicts) of the State of California.

parties hereto in reference to any employment of the Employee by the Company and
in reference to any of the matters or things herein provided for or hereinabove

corporation, partnership or business entity, or all or substantially all of the
Company's business or assets shall be transferred in any manner to any other
corporation, partnership or business entity, then such successor to the Company
shall thereupon succeed to, and be subject to, all rights, interests, duties and
obligations of, and shall thereafter be deemed for all purposes hereof to be,
the "Company" under this Agreement. This Agreement shall inure to the benefit of
and be enforceable by Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If
Employee should die, any amounts payable to him hereunder shall be paid in
accordance with the terms of this Agreement to Employee's devisee, legatee, or
other designee or, if there be no such designee, to his estate.

          (b) This Agreement is personal in nature and the Employee shall not,

Company, assign or transfer this Agreement or any rights or obligations
hereunder.

          (c) Except as set forth in subsection (a) above, nothing expressed or

give to any person, other than the parties to this Agreement, any right, remedy
or claim under or by reason of this Agreement or of any term, covenant or
condition of this Agreement.

     11. Amendments; Waivers. This Agreement may be amended, modified,
superseded, canceled, renewed or extended and the terms or covenants of this
Agreement may be waived only by a written instrument executed by the parties to
this Agreement or, in the case of a waiver, by the party waiving compliance. Any
such written instrument must be approved by the Board to be effective as against
the Company. The failure of any party at any time or times to require
performance of any provision of this Agreement shall in no manner affect the
right at a later time to enforce the same. No waiver by any party, of the
breach of any term or provision contained in this Agreement, whether by conduct
or otherwise, in any one or more instances, shall be deemed to be, or construed
as, a further or continuing waiver of any such breach, or a waiver of the breach
of any other term or covenant contained in this Agreement.

          (e) In addition to the circumstances described in subsection (a), (b),
(c) and (d) above, the Company may terminate the Employee's employment for any

at-will employee and may be terminated by the Company without cause or prior
notice pursuant to this subsection (e) notwithstanding any other provision
contained in this Agreement. This at-will relationship will remain in effect

Employee remains employed by the Company, unless such at-will employment
relationship is modified by a specific, express written agreement signed by the
Company.

          (f) If the Employee's employment is terminated pursuant to this
Section 4 or for any other reason, the Employee shall not be entitled to any

(as hereinafter defined).

               (i) For purposes of this Agreement, "Good Reason" shall mean a

<PAGE>

                    (A) All or substantially all of the assets of the Company
are sold or transferred to another corporation or entity; or

                    (B) The Company is sold, transferred, merged, consolidated,
ventured or reorganized into or with another corporation or entity, with the
result that upon conclusion of the transaction less than a majority of the
outstanding securities entitled to vote generally in the election of directors
or other capital interests of the acquiring corporation or entity are owned,
directly or indirectly, by the shareholders of the Company immediately prior to
the sale, transfer, merger, consolidation, venture or reorganization; or

                    (C) There is a report filed on Schedule 13D or Schedule
14D-1 (or any successor schedule, form or report), each as promulgated pursuant
to the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
disclosing that any person (as the term "person" is used in Section 13(d)(3) or
Section 14(d)(2) of the 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) of securities representing more
than 50% of the combined voting power of the then-outstanding voting securities
of the Company; or

                    (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-K thereunder or Item 14 of Schedule 14A
thereunder (or any successor schedule, form or report or item therein) that a
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) The individuals who, at the beginning of any period of
two consecutive calendar years, constituted members of the Board cease for any
reason to constitute at least a majority thereof unless the nomination for
election by the Company's stockholders of each new director of the Company was
approved by a vote of at least two-thirds of the directors of the Company still
in office who were Directors of the Company at the beginning of any such period.

               (iii) Notwithstanding the foregoing, a termination shall not be
treated as a termination for Good Reason (i) if Employee shall have specifically
consented in writing to the occurrence of the event giving rise to the claim of
termination for Good Reason or (ii) unless Employee, within 30 days after
receiving written notice from the Company specifying in reasonable detail the
occurrence of one of such events, shall have delivered a written notice to the
Company stating that he intends to terminate his employment for Good Reason and
specifying the factual basis for such termination and such event, if capable of
being cured, shall not have been cured within 30 days of the receipt by the
Company of such notice.

                                       5

               (iv) If Employee shall terminate his employment for Good Reason,
the Company shall pay Employee (or, in the event of his death, his devisee,
legatee or, if there is none, his estate) a lump-sum amount equal to the highest
level of Employee's annual Base Salary in effect on the date of the Change in
Control, multiplied by a factor of 2.0. Employee will also be entitled to any
vested benefits under any employee benefit plans.

     5. Employee's Representations.

          (a) The Employee represents that he has full authority to enter into
this Agreement and that he is free to enter into this Agreement and not under
any contractual restraint which would prohibit the Employee from satisfactorily
performing his duties to the Company under this Agreement.

          (b) The Employee hereby agrees to indemnify and hold harmless the
Company, its officers, directors and stockholders from and against any losses,
liabilities, damages or costs (including reasonable attorney's fees) arising out
of a breach, or claimed breach, of any of the representations, warranties and
covenants of the Employee set forth in this Agreement.

          (c) The Employee acknowledges that he is free to seek advice from
independent counsel with respect to this Agreement. The Employee has either
obtained such advice or, after carefully reviewing this Agreement, has decided
to forego such advice. The Employee is not relying on any representation or
advice from the Company or any of its officers, directors, attorneys or other
representatives regarding this Agreement, its content or effect.

     6. Arbitration. Any controversy or claim arising out of or relating to this
Agreement or any breach hereof or the Employee's employment by the Company or
termination thereof, shall be settled by arbitration by one arbitrator in
accordance with the rules of the American Arbitration Association, and judgment
upon such award rendered by the arbitrator may be entered in any court having
jurisdiction thereof. The arbitration shall be held in the City of San Diego or
such other place as may be agreed upon at the time by the parties to the
arbitration.

     7. Equitable Relief. The Employee acknowledges that the Company is
relying for its protection upon the existence and validity of the provisions of
this Agreement, that the services to be rendered by the Employee are of a
special, unique and extraordinary character, and that irreparable injury will
result to the Company from any violation or continuing violation of the
provisions of this Agreement for which damages may not be an adequate remedy.
Accordingly, the Employee hereby agrees that in addition to the remedies
available to the Company by law or under this Agreement, the Company shall be
entitled to obtain such equitable relief as may be permitted by law in a court
of competent jurisdiction including, without limitation, injunctive relief from
any violation or continuing violation by the Employee of any term or provision
of this Agreement.

                                       6

     8. Governing Law. This Agreement shall be governed by and construed and
enforced in accordance with the internal substantive laws (and not the laws of
conflicts) of the State of California.

     9. Entire Agreement. This Agreement constitutes the whole agreement of the
parties hereto in reference to any employment of the Employee by the Company and
in reference to any of the matters or things herein provided for or hereinabove
discussed or mentioned in reference to such employment; all prior agreements,
promises, representations and understandings relative thereto (including,
without limitation, the Prior Agreement) being herein merged.

     10. Assignability.

          (a) In the event the Company shall merge or consolidate with any other
corporation, partnership or business entity, or all or substantially all of the
Company's business or assets shall be transferred in any manner to any other
corporation, partnership or business entity, then such successor to the Company
shall thereupon succeed to, and be subject to, all rights, interests, duties and
obligations of, and shall thereafter be deemed for all purposes hereof to be,
the "Company" under this Agreement. This Agreement shall inure to the benefit of
and be enforceable by Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If
Employee should die, any amounts payable to him hereunder shall be paid in
accordance with the terms of this Agreement to Employee's devisee, legatee, or
other designee or, if there be no such designee, to his estate.

          (b) This Agreement is personal in nature and the Employee shall not,
except as set forth in subsection (a) hereof, without the written consent of the
Company, assign or transfer this Agreement or any rights or obligations
hereunder.

          (c) Except as set forth in subsection (a) above, nothing expressed or
implied in this Agreement is intended or shall be construed to confer upon or
give to any person, other than the parties to this Agreement, any right, remedy
or claim under or by reason of this Agreement or of any term, covenant or
condition of this Agreement.

     11. Amendments; Waivers. This Agreement may be amended, modified,
superseded, canceled, renewed or extended and the terms or covenants of this
Agreement may be waived only by a written instrument executed by the parties to
this Agreement or, in the case of a waiver, by the party waiving compliance. Any
such written instrument must be approved by the Board to be effective as against
the Company. The failure of any party at any time or times to require
performance of any provision of this Agreement shall in no manner affect the
right at a later time to enforce the same. No waiver by any party of the breach
of any term or provision contained in this Agreement, whether by conduct or
otherwise, in any one or more instances, shall be deemed to be, or construed as,
a further or continuing waiver of any such breach, or a waiver of the breach of
any other term or covenant contained in this Agreement.

facsimile transmission (with "answerback" confirmation of transmission), sent to
such parties' addresses or telecopy numbers as are set forth below such parties'
signatures to this Agreement, or such other addresses or telecopy numbers of

notice, request or consent shall be deemed effective upon the date of actual
receipt, receipt signature or confirmation of transmission, as applicable.

     13. Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     14. Survival. The representations and agreements of the Employee set forth
in Sections 5, 6 and 7 of this Agreement shall survive the expiration or
termination of this Agreement (irrespective of the reason for such expiration of
termination).

his or its rights under this Agreement, the prevailing party or parties shall be
entitled to recover reasonable fees, costs and expenses incurred in connection
therewith including, without limitation, the fees, costs and expenses of
attorneys, accountants and experts, whether or not litigation is instituted, and
including such fees, costs and expenses of appeals.
