or otherwise) arising out of, relating to, or resulting from Executives
employment with the Company, or the termination of Executives employment with
the Company, including any breach of this Agreement, shall be subject to
binding arbitration rules set forth in California Code of Civil Procedure
Section 1280 through 1294.2, including Section 1283.05 (the Rules) and

of 1964, the Americans with Disabilities Act of 1990, the Age Discrimination in
Employment Act of 1967, the Older Workers Benefit Protection Act, the
California Fair Employment and Housing Act, the California Labor Code, claims
of harassment, discrimination or wrongful termination and any statutory
claims.  Executive further understands
that this Agreement to arbitrate also applies to any disputes that the Company
may have with Executive.  9.2Procedure.  Executive agrees that any arbitration will
be administered by the American Arbitration Association (AAA) and that the
neutral arbitrator will be selected in a manner consistent with its National
rules for the Resolution of Employment Disputes.  Executive agrees that the arbitrator shall have the power to
decide any motions brought to any party to the arbitration, including motions
for summary judgment and/or adjudication and motions to dismiss and demurrers,
prior  9 
   to any arbitration hearing.  Executive also agrees that the arbitrator shall have the power to
award any remedies, including attorneys fees and costs, available under
applicable law.  Executive understands
the Company will pay for any administrative or hearing fees charged by the arbitrator
or AAA, except that Executive shall pay the first $125.00 of any filing fees
associated with any arbitration he initiates. 
Executive agrees that the arbitrator shall administer and conduct any
arbitration in a manner consistent with the rules and that to the extent that
the AAAs National Rules for the Resolution of Employment Disputes conflict
with the Rules, the Rules shall take precedence.  Executive agrees that the decision of the arbitrator shall be in
writing.  9.3Remedy.  Except as provided by the Rules and this
Agreement, arbitration shall be the sole, exclusive and final remedy for any
dispute between Executive and the Company. 
Accordingly, except as provided for and by the Rules and this Agreement,
neither Executive nor the Company will be permitted to pursue court action
regarding claims that are subject to arbitration.  Notwithstanding, the arbitrator will not have the authority to
disregard or refuse to enforce any lawful Company policy, and the arbitrator
shall not order or require the Company to adopt a policy not otherwise required
by law which the Company has not adopted.  9.4Availability
Of Injunctive Relief.  In

relief, Executive agrees that any party may also petition the court for
injunctive relief whether either party alleges or claims a violation of this
Agreement or any other agreement regarding trade secrets, confidential
information, nonsolicitation of Labor Code '2870.  Executive understands that any breach or threatened breach of
such an agreement will cause irreparable injury and that money damages will not
provide an adequate remedy therefor and both parties hereby consent to the
issuance of an injunction.  In the event
either party seeks injunctive relief, the prevailing party shall be entitled to
recover reasonable costs and attorney fees.  9.5Administrative
Relief.  Executive understands
that this Agreement does not prohibit Executive from pursuing an administrative
claim with a local, state or federal administrative body such as the Department
of Fair Employment and Housing, the Equal Employment Opportunity Commission, or
the Workers Compensation Board.  This
Agreement, however, does preclude Executive from pursing court action regarding
any such claim.  9.6Voluntary

Executive acknowledges and agrees that Executive is executing this
Agreement voluntarily and without any duress or undue influence by the Company
or anyone else.  Executive further
acknowledges and agrees that Executive has carefully read this Agreement and

provision in an employment agreement which provides that an employee shall
assign, or offer to assign, any of his or her rights in an invention to his or
her employer shall not apply to an invention that the employee developed
entirely on his or her own time without using the employers equipment,
supplies, facilities, or trade secret information except for those inventions
that either:  (1)Relate
at the time of conception or reduction to practice of the invention to the
employers business, or actual or demonstrably anticipate research or
development of the employer; or  (2)Result
from any work performed by the employee for the employer.  (b)To
the extent a provision in an employment agreement purports to require an
employee to assign an invention otherwise excluded from being required to be
assigned under subdivision (a), the provision is against the public policy of
this state and is unenforceable.
