              -------
Bonus") during the Employment Period in an amount to be determined prior to each
fiscal year by the Board and Executive. The Annual Bonus shall be structured, as
agreed upon by Executive and the Board in good faith, to provide for all or a

practice for other senior executives. Such company car shall be available for
Executive's use in a manner consistent with past practice for other senior
executives. Executive acknowledges and agrees that the Company may report all or

vacation during each year of the Employment Period, in addition to those legal
holidays observed

expenses incurred by him in the course of performing his duties under this
Agreement which are consistent with the terms of this Agreement and the
Company's policies in effect from time to time with respect to travel,
entertainment and other business expenses, subject to the Company's general
policies with respect to reporting and reasonable documentation of such
expenses.

              (vi)  The Company will provide a Country Club Membership of the
Executive's choice in San Joaquin County, and will pay the dues and any
assessments associated with such membership. Other charges in respect to this
account will be reimbursed in accordance with the Company's expense

<PAGE>

         (b) The Company and Executive each acknowledge the applicability of
Section 2870 of the California Labor Code. Accordingly, the provisions of
paragraph 7(a) shall not apply to, and the term "Work Product" shall not
include, any invention that Executive developed entirely on his own time without
using the Company's equipment, supplies, facilities, or trade secret information
except for those inventions that either: (i) relate at the time of conception or
reduction to practice of the invention to the Company's or any Subsidiary's
business, or to the actual or demonstrably anticipated research or development
of the Company or any Subsidiary; or (ii) result from any work performed by
Executive for the Company or any Subsidiary. Set forth on the attached "Excluded
Inventions Schedule" are the inventions Executive believes meet the criteria for
exclusion set forth above. Executive agrees to promptly advise the Company in
writing of any inventions developed after the Effective Date which Executive
believes meet the criteria for exclusion set forth above.

         (c) Executive shall promptly and fully disclose all Work Product to the
Company and shall cooperate and perform all actions reasonably requested by the
Company (whether during or after the Employment Period) to establish, confirm
and protect the Company's right, title and interest in such Work Product.

Company, at the Company's expense, to secure the Company's rights in the Work
Product in any and all countries, including the execution of all applications
and all other instruments and documents which the Company shall deem necessary
in order to apply for and obtain rights in such Work Product and in order to
assign and convey to the Company the sole and exclusive right, title and
interest in and to such Work Product. If the Company is unable because of
Executive's mental or physical incapacity or for any other reason (including
Executive's refusal to do so after request therefor is made by the Company) to
secure Executive's signature to apply for or to pursue any application for any
United States or foreign patents or copyright registrations covering Work
Product belonging to or assigned to the Company pursuant to paragraph 7(a)
above, then Executive hereby irrevocably designates and appoints the Company and
its duly authorized officers and agents as Executive's agent and
attorney-in-fact to act for and in Executive's behalf and stead to execute and
file any such applications and to do all other lawfully permitted acts to
further the prosecution and issuance of patents or copyright registrations
thereon with the same legal force and effect as if executed by Executive.
Executive agrees not to apply for or pursue any application for any United
States or foreign patents or copyright registrations covering any Work Product
other than pursuant to this paragraph in circumstances where such patents or
copyright registrations are or have been or are required to be assigned to the
Company.

in Executive's possession or within his control irrespective of the location or
form of such material and, if requested by the Company, shall provide the
Company with written confirmation that all such materials have been delivered to

9.       Subsequent Inventions. Executive understands and agrees that all
         ---------------------
Intellectual Property Rights made, conceived, developed, or reduced to practice
by Executive, either alone or jointly with others, shall be disclosed to the
Company by Executive for six (6) months following the termination of Executive's
employment with the Company. Employee further agrees that all Intellectual
Property Rights made, conceived, developed or reduced to practice within six (6)
months following such termination shall be presumed to have been conceived
during Executive's employment with the Company and with the use of the Company's
Confidential Information, but such presumption may be overcome by Executive by a
showing that such Intellectual Property Rights were conceived after such
employment and without the use of any such Confidential Information. In the
event Executive is not able to rebut such presumption and prove that such
Intellectual Property Rights were conceived after such employment and without
the use of Confidential Information, Executive agrees to assign all right, title
and interest in such Intellectual Property Rights to the Company.

10.      Disclosure.  Following the termination of Executive's employment with
         ----------
the Company, Executive shall communicate the restrictions contained in this
Agreement to any Person he intends to be employed by, provide consulting
services to or otherwise represent. Executive hereby consents to the Company's
communication of the restrictions contained in this Agreement to any such
Person.

paragraphs 6, 7, 8, 9 or 10 (the "Protective Covenants"), a court shall hold
that the duration or scope stated therein are unreasonable under circumstances
then existing, the parties hereto agree that the maximum duration or scope
reasonable under such circumstances shall be substituted for the stated duration
or scope and that the court shall be allowed to revise the restrictions
contained therein to cover the maximum period or scope permitted by law;
provided that in no event shall the duration or scope determined by such court
exceed the duration or scope set forth in this Agreement. Executive has
consulted legal counsel regarding the Protective Covenants and based on such
consultation has determined and hereby acknowledges that the Protective
Covenants are reasonable in terms of duration and scope and are necessary to
protect the goodwill of the Company's business and the Confidential Information.

         (b) If Executive breaches, or threatens to commit a breach of, any of
the Protective Covenants, the Company shall have the following rights and
remedies, each of which rights and remedies shall be independent of the others
and severally enforceable, and each of which is in addition to, and not in lieu
of, any other rights and remedies available to the Company at law or in equity:

             (i) The right and remedy to have the Protective Covenants
specifically enforced by any court of competent jurisdiction (without the need
to post a bond or other security), it being agreed that any breach or threatened
breach of the Protective Covenants

                                       7

<PAGE>

would cause irreparable injury to the Company and that money damages would not
provide an adequate remedy to the Company; and

             (ii) The right and remedy to require Executive to account for and
pay over to the Company any profits, monies, accruals, increments or other
benefits derived or received by Executive as the result of any transaction(s)
constituting a breach of the Protective Covenants.

         (c) In the event of any breach or violation by Executive of any of the
Protective Covenants, the time period of such covenant with respect to Executive
(to the extent such covenant is limited in duration) shall be tolled until such
breach or violation is resolved.

         ------------------------------------

         (a) The Executive shall not during the Employment Period and during the
period Executive is receiving any Severance Payment pursuant to paragraph 5(a)
(the "Noncompete Period"), for himself or on behalf of any other person, firm,
partnership, corporation, or other entity, engage, directly or indirectly,

owner of not more than 5% of the outstanding stock of any class of a corporation
which is publicly traded; and provided further that the restrictions set forth
in this paragraph 12 shall not restrict the activities of Executive to the
extent Executive has received the consent of the Board to such activities.

         (b) For purposes of this Agreement, "Restricted Territories" shall mean
any states or comparable jurisdictions in which the Company or its Subsidiaries
