Registrant's  Proxy  Statement  No.  001-08966  pursuant to Section 14(a) of the
Exchange Act, filed with the SEC on March 28, 2003.

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 Exchange 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  Registrant's
Long-Term Incentive Plan.

                  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
Exchange 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.

                  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 SEC,
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 San Jose, State of California on this
2nd day of May, 2003.
