controversy arising from or concerning the interpretation or application of this
Agreement or its subject matter, the parties agree that such controversy shall
be resolved exclusively through binding arbitration before a single neutral
arbitrator selected jointly by the parties.  The Company shall be responsible
for 100% of the fees and expenses of the arbitrator.  Each party shall be
responsible for 100% of its own attorneys' fees and any other costs occasioned
by the arbitration, without regard to which party to the controversy prevails;
provided, that the arbitrator may award attorneys' fees and costs to a party
when so empowered by law.  The parties to the arbitration shall have all rights,
remedies, and defenses available to them in a civil action for the issues in
controversy.  If, for any legal reason, a controversy arising from or concerning
the interpretation or application of this Agreement or its subject matter cannot
be arbitrated as provided in this Section 7, the parties agree that any civil
action shall be brought in the United States District Court for the Northern
District of California or, only if there is no basis for federal jurisdiction,
in the Superior Court of the State of California in and for the City and County
of San Francisco.  The parties further agree that any such civil action shall be
tried to the court, sitting without a jury.
8. Cooperation with the Company After Termination of
the Employment Period.  Following termination of the Employment Period by
Executive, Executive shall fully cooperate with the Company in all matters
relating to the winding up of his pending work on behalf of the Company and the
orderly transfer of any such pending work to other employees of the Company as
may be designated by the Company.
9. Confidentiality; Return of Property;  Non-Solicitation
of Employees.
(a)	The Executive acknowledges that during the
Employment Period he will receive confidential information from the Company and
subsidiaries of the Company and the respective customers thereof (each a
"Relevant Entity").  Accordingly, the Executive agrees that
during the Employment Period (as it may be extended from time to time) and
thereafter for a period of two years, the Executive and his affiliates shall
not, except in the performance of his obligations to the Company hereunder or as
may otherwise be approved in advance by the Company, directly or indirectly,
disclose or use (except for the direct benefit of the Company) any confidential
information that he may learn or has learned by reason of his association with
any Relevant Entity.  Upon termination of this Agreement, the Executive shall
promptly return to the Company any and all properties, records or papers of any
Relevant Entity, that may have been in his possession at the time of
termination, whether prepared by the Executive or others, including, but not
limited to, confidential information and keys.  For purposes of this Agreement,
"confidential information" includes all data, analyses,
reports, interpretations, forecasts, documents and information concerning a
Relevant Entity and its affairs, including, without limitation with respect to
clients, products, policies, procedures, methodologies, trade secrets and other
intellectual property, systems, personnel, confidential reports, technical
information, financial information, business transactions, business plans,
prospects or opportunities, (i) that the Company reasonably believes are
confidential or (ii) the disclosure of which could be injurious to a Relevant
Entity or beneficial to competitors of a Relevant Entity, but shall exclude any
information that (x) the Executive is required to disclose under any applicable
laws, regulations or directives of any government agency, tribunal or authority
having jurisdiction in the matter or under subpoena or other process of law, (y)
is or becomes publicly available prior to the Executive's disclosure or use of
the information in a manner violative of the second sentence of this Section 9
(a), or (z) is rightfully received by Executive without restriction or
disclosure from a third party legally entitled to possess and to disclose such
information without restriction (other than information that he may learn or has
learned by reason of his association with any Relevant Entity).  For purposes of
this Agreement, "affiliate" means any entity that, directly or
indirectly, is controlled by, or under common control with, the Executive.  For
purposes of this definition, the terms "controlled" and
"under common control with" means the possession, direct or
indirect, of the power to direct or cause the direction of the management and
policies of such person, whether through the ownership of voting stock, by
contract or otherwise.
(b)	For a period of one year following the termination of
Executive's employment with the Company for any reason, he will not, without the
Company' express written consent, either on his own behalf or on behalf of
another, solicit employees of the Company or any subsidiary of the Company for
the purpose of hiring them.  General employment advertising shall not be deemed
to be a solicitation.
10. General.
10.1	Indemnification.  In the event Executive
is made, or threatened to be made, a target, subject, witness or party to any
civil, criminal or administrative action, proceeding or investigation by reason
of the fact that Executive is or was a director or officer of the Company, or
serves or served any other corporation fifty percent (50%) or more owned by the
Company in any capacity at the Company's request, or serves or served as a
director of any other corporation at the Company's request, or serves or served
as a fiduciary of any ERISA plan at the Company's request, Executive shall be
indemnified by the Company for all amounts paid as a fine or settlement or
judgment, and the Company shall pay without any undertaking the Executive's
defense costs when and as incurred, all to the fullest extent permitted by
law.
10.2	Waiver.  Neither party shall, by mere lapse of
time, without giving notice or taking other action hereunder, be deemed to have
waived any breach by the other party of any of the provisions of this Agreement.
Further, the waiver by either party of a particular breach of this Agreement by
the other shall neither be construed as nor constitute a continuing waiver of
such breach or of other breaches by the same or any other provision of this
Agreement.
10.3	Severability.  If for any reason a court of
competent jurisdiction or arbitrator finds any provision of this Agreement be
unenforceable, the provision shall be deemed amended as necessary to conform to
applicable laws or regulations, or if it cannot be so amended without materially
altering the intention of the parties, the remainder of the Agreement shall
continue in full force and effect as if the offending provision were not
contained herein.
10.4	Notices.  All notices and other communications
required or permitted to be given under this Agreement shall be in writing and
shall be considered effective upon personal service or upon transmission of a
facsimile or the deposit with Federal Express or in Express Mail and addressed
to the Board of Directors of the Company at its principal corporate address, and
to Executive at his most recent address shown on the Company's corporate
records, or at any other address which he may specify in any appropriate notice
to the Company.
10.5	Counterparts.  This Agreement may be executed
in any number of counterparts, each of which shall be deemed an original and all
of which taken together constitutes one and the same instrument and in making
proof hereof it shall not be necessary to produce or account for more than one
such counterpart.
10.6	Entire Agreement.  The parties hereto
acknowledge that each has read this Agreement, understands it, and agrees to be
bound by its terms.  The parties further agree that this Agreement shall
constitute the complete and exclusive statement of the agreement between the
parties and supersedes all proposals (oral or written), understandings,
representations, conditions, covenants, and all other communications between the
parties relating to the subject matter hereof.
10.7	Governing Law.  This Agreement shall be
governed by the law of the State of California.
10.8	Assignment and Successors.  The Company shall
have the right to assign its rights and obligations under this Agreement to an
entity which acquires substantially all of the assets of the Company, whether by
merger or otherwise.  The rights and obligations of the Company under this
Agreement shall inure to the benefit and shall be binding upon the successors
and assigns of the Company.
