------    ---------------------------------------

          The following documents filed with the Securities and Exchange

          (a)  The Registrant's latest annual report filed pursuant to Section
               13(a) or 15(d) of the Securities Exchange Act of 1934, as amended

                                      -2-
<PAGE>

          The validity of the issuance of the shares of Common Stock offered
hereby will be passed upon for the Registrant by Fenwick & West LLP, of Palo
Alto, California. Members of the firm of Fenwick & West LLP own an aggregate of
approximately 7,000 shares of Common Stock of the Registrant.

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

          Section 145 of the Delaware General Corporation Law 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 the Delaware General Corporation Law, the Registrant's
Certificate of Incorporation includes a provision that eliminates the personal
liability of its directors for monetary damages for breach of fiduciary duty as
a director, except for liability:

          .    for any breach of the director's duty of loyalty to the
               Registrant or its stockholders,

          .    for acts or omissions not in good faith or that involve
               intentional misconduct or a knowing violation of law,

          .    under section 174 of the Delaware General Corporation Law
               (regarding unlawful dividends and stock purchases), or

          .    for any transaction from which the director derived an improper
               personal benefit.


          As permitted by the Delaware General Corporation Law, the Registrant's
Bylaws provide that:

          .    the Registrant is required to indemnify its directors and
               officers to the fullest extent permitted by the Delaware General
               Corporation Law, subject to certain very limited exceptions,

          .    the Registrant may indemnify its other employees and agents as
               set forth in the Delaware General Corporation Law,

          .    the Registrant is required to advance expenses, as incurred, to
               its directors and officers in connection with a legal proceeding
               to the fullest extent permitted by the Delaware General
               Corporation Law, subject to certain very limited exceptions, and

          .    the rights conferred in the Bylaws are not exclusive.


          The Registrant has entered into Indemnity Agreements with each of its
current directors and officers to give such directors and officers additional
contractual assurances regarding the scope of the indemnification set forth in
the Registrant's Amended and Restated Certificate of Incorporation and to
provide additional procedural protections. At present, there is no pending
litigation or proceeding involving a director, officer or employee of the
Registrant regarding

                                      -3-
<PAGE>

which indemnification is sought, nor is the Registrant aware of any threatened
litigation that may result in claims for indemnification.

          Reference is also made to Section 7 of the Underwriting Agreement
relating to the Registrant's secondary public offering, effected pursuant to the
Registrant's Registration Statement on Form S-1 (Registration No. 333-92943)
originally filed with the Commission on December 17, 1999, as subsequently
amended, which provides for the indemnification of officers, directors and
controlling persons of the Registrant against certain liabilities. The
indemnification provisions in the Registrant's Amended and Restated Certificate
of Incorporation, Bylaws and the Indemnity Agreements to be entered into between
the Registrant and each of its directors and officers may be sufficiently broad
to permit indemnification of the Registrant's directors and officers for
liabilities arising under the Securities Act.

          The Registrant maintains directors' and officers' liability insurance.

          See also the undertakings set out in response to Item 9.


          Reference is made to the following documents filed as exhibits to this
Registration Statement regarding relevant indemnification provisions described
above and elsewhere herein:

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 of 1933;

               (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 the 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 and 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 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
-------
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act of 1934 that are incorporated by reference in the Registration
Statement.

          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, 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 which remain unsold at the
termination of the offering.

          The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Exchange Act of 1934) 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.

                                      -5-
<PAGE>

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the 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 whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

Item 4.   Description of Securities.

          Not applicable.

Item 5.   Interests of Named Experts and Counsel.
------    --------------------------------------

                                      -2-
The validity of the issuance of the shares of Common Stock offered
hereby will be passed upon for the Registrant by Fenwick & West LLP, of Palo
Alto, California. Members of the firm of Fenwick & West LLP own an aggregate of
approximately 7,000 shares of Common Stock of the Registrant.

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

          Section 145 of the Delaware General Corporation Law 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 the Delaware General Corporation Law, the Registrant's
Certificate of Incorporation includes a provision that eliminates the personal
liability of its directors for monetary damages for breach of fiduciary duty as
a director, except for liability:

          .    for any breach of the director's duty of loyalty to the
               Registrant or its stockholders,

          .    for acts or omissions not in good faith or that involve
               intentional misconduct or a knowing violation of law,

          .    under section 174 of the Delaware General Corporation Law
               (regarding unlawful dividends and stock purchases), or

          .    for any transaction from which the director derived an improper
               personal benefit.

          As permitted by the Delaware General Corporation Law, the Registrant's
Bylaws provide that:

          .    the Registrant is required to indemnify its directors and
               officers to the fullest extent permitted by the Delaware General
               Corporation Law, subject to certain very limited exceptions,

          .    the Registrant may indemnify its other employees and agents as
               set forth in the Delaware General Corporation Law,

          .    the Registrant is required to advance expenses, as incurred, to
               its directors and officers in connection with a legal proceeding
               to the fullest extent permitted by the Delaware General
               Corporation Law, subject to certain very limited exceptions, and

          .    the rights conferred in the Bylaws are not exclusive.

          The Registrant has entered into Indemnity Agreements with each of its
current directors and officers to give such directors and officers additional
contractual assurances regarding the scope of the indemnification set forth in
the Registrant's Amended and Restated Certificate of Incorporation and to
provide additional procedural protections. At present, there is no pending
litigation or proceeding involving a director, officer or employee of the
Registrant regarding

                                      -3-
which indemnification is sought, nor is the Registrant aware of any threatened
litigation that may result in claims for indemnification.

          Reference is also made to Section 7 of the Underwriting Agreement
relating to the Registrant's secondary public offering, effected pursuant to the
Registrant's Registration Statement on Form S-1 (Registration No. 333-92943)
originally filed with the Commission on December 17, 1999, as subsequently
amended, which provides for the indemnification of officers, directors and
controlling persons of the Registrant against certain liabilities. The
indemnification provisions in the Registrant's Amended and Restated Certificate
of Incorporation, Bylaws and the Indemnity Agreements to be entered into between
the Registrant and each of its directors and officers may be sufficiently broad
to permit indemnification of the Registrant's directors and officers for
liabilities arising under the Securities Act.

          The Registrant maintains directors' and officers' liability insurance.

          See also the undertakings set out in response to Item 9.

          Reference is made to the following documents filed as exhibits to this
Registration Statement regarding relevant indemnification provisions described
above and elsewhere herein:

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 of 1933;

               (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 the 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 and 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 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
-------
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act of 1934 that are incorporated by reference in the Registration
Statement.

          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, 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 which remain unsold at the
termination of the offering.

          The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Exchange Act of 1934) 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.

                                      -5-
Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the 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 whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                                      -6-
