         (d) The Registrant's Registration Statement on Form 8-A, filed with the
             Commission on October 31, 1997, pursuant to Section 12(g) of the
             1934 Act, and as amended on Form 8-A/A on December 13, 1999 and
             April 10, 2000 in which there is described the terms, rights and
             provisions applicable to the Registrant's Preferred Share Purchase

         after the date of this Registration Statement and prior to the filing
         of a post-effective amendment which indicates that all securities
         offered hereby have been sold or which de-registers all securities

         of filing of such documents. Any statement contained in a document
         incorporated or deemed to be incorporated by reference herein shall be
         deemed to be modified or superseded for purposes of this Registration

Item 5.  Interests of Named Experts and Counsel

Item 6.  Indemnification of Directors and Officers

                  Section 145 of the Delaware General Corporation Law permits a
corporation to include in its charter documents, and in agreements between the
corporation and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.


                                      II-1



                  Article X of the Registrant's Restated Certificate of
Incorporation provides for the indemnification of directors to the fullest
extent permissible under Delaware Law.

                  Article VII of the Registrant's Bylaws provides for the
indemnification of officers, directors and third parties to the fullest extent
permissible under Delaware Law, which provisions are deemed to be a contract
between the Registrant and each director and officer who serves in such capacity
while such bylaw is in effect.

                  The Registrant has entered into indemnification agreements
with its directors and executive officers, in addition to the indemnification
provided for in the Registrant's Bylaws, and intends to enter into
indemnification agreements with any new directors and executive officers in the
future. The Registrant has also obtained liability insurance for the benefit of
its directors and officers.

     Statement of Form S-8 (File No. 333-90643) as filed with the Securities and
     Exchange Commission on November 9, 1999.


Item 9.  Undertakings

                  A. The undersigned Registrant hereby undertakes: (1) to file,
during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement: (i) to include any prospectus required
by Section 10(a)(3) of the 1933 Act, (ii) to reflect in the prospectus any facts
or events arising after the effective date of this Registration Statement (or
the most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in this
Registration Statement and (iii) to include any material information with
respect to the plan of distribution not previously disclosed in this
Registration Statement or any material change to such information in this
Registration Statement; provided, however, that clauses (1)(i) and (1)(ii) shall
not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the 1934 Act that are
incorporated by reference into this Registration Statement; (2) that for the
purpose of determining any liability under the 1933 Act each such post-effective
amendment shall be deemed to be a new registration statement relating to the
securities offered therein and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof; and (3) to remove
from registration by means of a post-effective amendment any of the securities
being registered which remain unsold at the termination of the offering.

                  B. The undersigned Registrant hereby undertakes that, for
purposes of determining any liability under the 1933 Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
1934 Act that is incorporated by reference into this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.


                                      II-2


                  C. Insofar as indemnification for liabilities arising under
the 1933 Act may be permitted to directors, officers or controlling persons of
the Registrant pursuant to the indemnification provisions summarized in Item 6
or otherwise, the Registrant has been advised that, in the opinion of the
Commission, such indemnification is against public policy as expressed in the
1933 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the 1933 Act and
will be governed by the final adjudication of such issue.



                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, as amended, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of  the  requirements  for  filing  on  Form  S-8,  and  has  duly  caused  this
Registration Statement to be signed on its behalf by the undersigned,  thereunto
duly authorized,  in the City of Mountain View, State of California on this 24th
day of February, 2003.

         Re:      Registration Statement on Form S-8

Ladies and Gentlemen:

     We have examined the Registration  Statement on Form S-8 to be filed by you
with  the  Securities  and  Exchange   Commission  on  February  24,  2003  (the
"Registration   Statement")  in  connection  with  the  registration  under  the
Securities  Act of  1933,  as  amended  (the  "Securities  Act"),  of  3,302,258
additional  shares of your Common Stock  reserved  for  issuance  under the 1998
Nonstatutory  Stock Option Plan (the  "Plan").  As your legal  counsel,  we have
examined the proceedings taken and are familiar with the proceedings proposed to
be taken by you in  connection  with the sale and  issuance of such Common Stock
under the Plan.

     It is our opinion that,  when issued and sold in the manner  referred to in
the Plan and pursuant to the  agreements  which  accompany the Plan,  the Common
Stock issued and sold thereby will be legally and validly issued, fully paid and
non-assessable.

     We  consent to the use of this  opinion  as an exhibit to the  Registration
Statement and further  consent to the use of our name wherever  appearing in the
Registration Statement and any subsequent amendment thereto.

                                  Very truly yours,
