Item 4.   Description of Securities.
------    -------------------------

               Not applicable.

Item 5.   Interests of Named Experts and Counsel.
------    --------------------------------------
               Not applicable.


Item 6.   Indemnification of Directors and Officers and Limitation of Liability.
------    ---------------------------------------------------------------------

        Section 145 of the Delaware General Corporation Law (the "DGCL")
authorizes a court to award, or a corporation's board of directors to grant,
indemnity to directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act.

        As permitted by Section 107 of the DGCL, the Registrant's Certificate of
Incorporation, as amended, includes a provision that eliminates the personal
liability of its directors to the Registrant or its stockholders for

                                      II-1



monetary damages for breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the DGCL regarding unlawful payments of dividends and unlawful
stock purchases or redemptions) or (iv) for any transaction from which the
director derived an improper personal benefit.

        In addition, as permitted by Section 145 of the DGCL, the Bylaws of the
Registrant, as amended, provide that:

          (i)   the Registrant is required to indemnify to the fullest extent
authorized by law, subject to certain very limited exceptions, any person who
was or is made a party or is threatened to be made a party to or is otherwise
involved in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that she or he is or was
a director or officer of the Registrant or is or was serving at the request of
the Registrant as a director, officer, employee or agent of another corporation
or of a partnership, joint venture, trust or other enterprise, including service
with respect to an employee benefit plan (an "indemnitee"), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid in settlement reasonably incurred or
suffered by such person in connection therewith);

          (ii)  the Registrant is required to advance expenses, as incurred, to
its indemnitees in connection with defending a legal proceeding; provided,
however, that, if the DGCL so requires, an advancement of expenses to a director
or officer will be made only if an undertaking is delivered to the corporation
to repay all amounts advanced if it is ultimately determined that
indemnification is unavailable;

          (iii) an indemnitee may bring suit against the Registrant to recover
the unpaid amount of any claim within 60 days after a written claim has been
received by the Registrant;

          (iv)  the rights conferred in the Bylaws, as amended, are not
exclusive. The Registrant's obligation to indemnify an indemnitee must be
reduced by any amounts such indemnitee receives (1) from insurance policies
purchased by the Registrant, (2) from another corporation, partnership, joint
venture, trust or other enterprise for whom the indemnitee was serving at the
request of the Registrant, or (3) under any other applicable indemnification
provision;

          (v)   the Registrant may indemnify and advance expenses to employees
and agents of the Registrant to the same extent as it provides indemnification
and advancement of expenses to its directors and officers, except as otherwise
directed by law, its Certificate of Incorporation, the bylaws, agreement or
vote.

        The Registrant has entered into Indemnification Agreements with each of
its current directors and executive officers to give such directors and
executive officers additional contractual assurances regarding the scope of the
indemnification set forth in Registrant's Certificate of Incorporation and to
provide additional procedural protections.

        The Registrant, with approval by the Registrant's Board of Directors,
has obtained directors' and officers' liability insurance.

Item 9.   Undertakings.
------    ------------

              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 Securities Act;

              (ii)  To reflect in the prospectus any facts or events arising
after the effective date of the 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 the Registration
Statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20 percent change in the
maximum aggregate offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement.

              (iii) To include any material information with respect to the plan
of distribution not previously disclosed in the Registration Statement or any
material change to such information in the Registration Statement.

     Provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if
     --------  -------
the Registration Statement is on Form S-3 or Form S-8 or Form F-3, and 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 in the Registration Statement.

     (2)      That, for the purpose of determining any liability under the
Securities 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.

     (3)      To remove from registration by means of a post-effective amendment
any of the securities being registered that remain unsold at the termination of
the offering.

     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the 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.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions discussed in Item 6 hereof, or otherwise,
the Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities 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 hereby, 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

                                      II-4



whether such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                                   SIGNATURES

               Pursuant to the requirements of the Securities Act of 1933, 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 the 21st day
of September, 2001.
