lieu of, all other accrued, vested or deferred compensation, rights, options or

employment, including but not limited to accrued sick pay and vacation pay,

such Participant upon termination of employment pursuant to any applicable law
or other severance program or arrangement. For this purpose, unemployment

                  3. Confidentiality. The benefits provided in Section 2 are
expressly conditioned upon Participant's agreement not to, directly or
indirectly, for a period of one (1) year after his or her Date of Termination,

payments due hereunder all taxes which, by applicable federal, state, local or
other law, it is required to withhold therefrom.

perform fully in accordance with the terms hereof, the Company shall reimburse
such Participant, on a current basis, for all reasonable legal fees and
expenses, if any, reasonably incurred by such in connection with such contest or
dispute (to the extent the Participant prevails in such contest or dispute),
provided, that, if it is determined by a court or by arbitration that such
Participant did not enter into the contest or dispute in good faith, such
Participant shall be obligated to return to the Company such reimbursed fees and
expenses. All disputes hereunder shall be settled exclusively by arbitration in
the State of California in accordance with the rules of the American Arbitration
Association then in effect. Judgment may be entered on the arbitration award in
any court having jurisdiction. The Company shall bear all costs and expenses in
connection with the retention of the arbitration panel for any proceeding.

<PAGE>
                  6. Termination or Amendment of Plan.

                  (a) Subject to paragraph (b) below, this Plan shall be in
effect as of May 3, 2001.

                  (b) The Board shall have the right at any time prior to a
Change of Control, in its sole discretion, to terminate or amend the Plan, which
right includes, but is not limited to, the right to add any person to the Plan
as a Participant or to remove any Person from the Plan as a Participant. In no
event shall this Plan be terminated or amended following a Change of Control in
any manner which would adversely affect the rights or potential rights of a
Participant (or his or her dependents) under this Plan with respect to such
Change of Control.

                  7. Successors.

                  (a) This Plan shall not be terminated by any merger,
consolidation, share exchange or similar event involving the Company whereby the
Company is or is not the surviving or resulting entity. In the event of any
merger, consolidation, share exchange or similar event, the provisions of this
Plan shall be binding upon the surviving or resulting corporation or the person
or entity to which the Company's assets are transferred.

                  (b) Concurrently with any merger, consolidation, share
exchange or sale, lease or transfer of all or substantially all of its assets,
the Company will cause any successor or transferee unconditionally to assume all
of the obligations of the Company hereunder.

                  (c) This Plan shall inure to the benefit of and be enforceable
by each Participant's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If a
Participant shall die while any amounts are payable to such Participant
hereunder, all such amounts, unless otherwise provided herein, shall be paid in
accordance with the terms of this Plan to such Participant's surviving spouse
or, if none, to such Participant's estate.

                  8. No Mitigation, Offset. The obligation of the Company to
provide a Participant with the benefits specified in Section 2 and otherwise to
perform its obligations hereunder shall not be affected by any set-off,
counterclaim, recoupment, defense or other claim, right or action which the
Company may have against such Participant or others. In no event shall a
Participant be obligated to seek other employment or take other action by way of
mitigation of the amounts payable to such Participant under any of the
provisions of this Plan and such amounts shall not be reduced whether or not
such Participant obtains other employment, except as provided in Section
2(a)(ii) of this Plan.

<PAGE>
                  9. Governing Law; Law Validity. The interpretation,
construction and performance of this Plan, unless preempted by the Standard
Participant Retirement Income Security Act of 1974, as amended ("ERISA"), shall
be governed by and construed and enforced in accordance with the laws of the
State of California without regard to the principle of conflicts of laws. The
invalidity or unenforceability of any provision of this Plan shall not affect
the validity or enforceability of any other provision of this Plan, which other
provisions shall remain in full force and effect.

                  10. Administration. The Plan shall be administered by the
Administrator. Consistent with the requirements of ERISA and the regulations of
the Department of Labor, the Administrator shall provide adequate written notice
to any Participant covered by the Plan whose claim for a Separation Benefit or
other benefits hereunder has been denied, setting forth specific reasons for
such denial, written in a manner calculated to be understood by such Participant
and affording such Participant a full and fair review of the decision denying
the claim.

                  11. Miscellaneous.

                  (a) The Company shall not be required to fund or otherwise
segregate assets to be used for the payment of any benefits under the Plan. The
Company shall make such payments only out of its general corporate funds, and
therefore its obligation to make such payments shall be subject to any claims of
its other creditors having priority as to its assets.

                  (b) This Plan does not constitute a contract of employment or
impose on the Company any obligation to retain a Participant as an officer or
employee (as the case may be), to retain a Participant as a Participant (prior
to a Change in Control), not to change the status of a Participant's employment,
or not to change the policies of the Company regarding termination of
employment.

                  (c) No rights of any Participant (or beneficiary) to payments
of any amounts under the Plan shall be sold, exchanged, transferred, assigned,
pledged, hypothecated or otherwise disposed of other than by will or by the laws
of descent and distribution.

                  (d) Unless the Company specifically provides otherwise, any
benefits payable under this Plan shall not be taken into account for purposes of
determining benefits payable to a Participant under any other benefit plan or
program.

                  (e) The Company's obligations hereunder shall be subject to
all applicable laws, and the Separation Benefit and other benefits payable
hereunder may be adjusted to comply with any such laws.
