     7.   CIVIL CODE SECTION 1542.  Employee represents that Employee is not
aware of any claims against the Company other than the claims that are released
by this Release.  Employee acknowledges that she has been advised by legal
counsel and is familiar with the provisions of California Civil Code
Section 1542, which provides as follows:

               A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE
               CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT
               THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM
               MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE
               DEBTOR.

     Employee acknowledges that she is aware of and understands the Civil Code
Section set forth above and agrees expressly to waive any rights she may have
thereunder, as well as under any other statute or common law principles of
similar effect.

maintain in confidence the existence of this Release, the substance of this
Release, and the consideration for this Release (collectively, the "Settlement
Information").  Employee agrees to take all reasonable precautions to prevent
disclosure of any Settlement Information to third parties, and agrees that there
will not cause any public disclosure, directly or indirectly, of any Settlement
Information.  Employee agrees to disclose Settlement Information only to those
attorneys, accountants, governmental entities, and family members who have a
reasonable need to know the information.

     9.   NO ADMISSION OF LIABILITY.  Employee understands and acknowledges that
this Release constitutes a compromise and settlement of disputed claims.  No
action taken by the Company, either previously or in connection with this
Release shall be deemed or construed to be either: (a) an admission of the truth
or falsity of any claims heretofore made; or (b) an acknowledgment or admission
by the Company of any fault or liability whatsoever to the Employee or to any
third party.

     10.  COSTS.  The Parties shall each bear their own costs, expert fees,
attorneys' fees and other fees incurred in connection with this Release.

     11.  ARBITRATION.  The Parties agree that any and all disputes arising out
of the terms of this Release, their interpretation, and any of the matters
herein released, including any potential claims of harassment, discrimination or
wrongful termination, shall be subject to binding arbitration, to the extent
permitted by law, in its offices in San Francisco County, California, or at a
mutually agreeable location in San Mateo County, California, before the American
Arbitration Association under its National Rules for the Resolution of
Employment Disputes.  EMPLOYEE AGREES AND HEREBY WAIVES HER RIGHT TO JURY TRIAL
AS TO MATTERS ARISING OUT OF THE TERMS OF THIS RELEASE AND ANY MATTERS HEREIN
RELEASED TO THE EXTENT PERMITTED BY LAW.  In the event that Employee is in
breach of any of its obligations under this Release, nothing in this section is
to be construed as a waiver of the Company's rights to seek injunctive or
equitable relief in a court of competent jurisdiction and to recover its costs
and attorneys' fees and

expenses. The Parties agree that the prevailing party in any arbitration shall
be entitled to injunctive relief in any court of competent jurisdiction to
enforce the arbitration award.

capacity to act on her own behalf and on behalf of all who might claim through
Employee to bind them to the terms and conditions of this Release.

     13.  NO REPRESENTATIONS.  Employee represents that Employee has had the
opportunity to consult with an attorney, and has carefully read and understands
the scope and effect of the provisions of this Release.  Neither party has
relied upon any representations or statements made by the other party hereto
which are not specifically set forth in this Release.

     14.  SEVERABILITY.  In the event that any provision hereof becomes or is
declared by a court of competent jurisdiction to be illegal, unenforceable or
void, this Release shall continue in full force and effect without said
provision.

     15.  ENTIRE AGREEMENT.  This Release,  the stock option agreements between
the parties, the Employee Confidentiality and Nonsolicitation Agreement, and the
Employee's Affiliate Agreement, represent the entire agreement and understanding
between the Company and Employee concerning Employee's separation from the
Company, and supersede and replace any and all prior agreements and
understandings concerning Employee's relationship with the Company and her
compensation by the Company.  This Release may only be amended in writing signed
by Employee and the Company's Vice President, Legal, and General Counsel.

     16.  GOVERNING LAW.  This Release shall be governed by the internal
substantive laws, but not the choice of law rules, of the State of California.

     17.  EFFECTIVE DATE.  This Release is effective eight (8) days after it has
been signed by both Parties.
