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

     The following documents filed with the Securities and Exchange Commission
(the "Commission") are incorporated herein by reference:

     (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 (the
          "Exchange Act") or the latest prospectus filed pursuant to Rule 424(b)

<PAGE>

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

     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

                                       3
<PAGE>

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

     The indemnification provisions in the Registrant's Amended and Restated
Certificate of Incorporation, Bylaws and the Indemnity Agreements entered or 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.

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.

     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,

                                       5
<PAGE>

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.

     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

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

     The following documents filed with the Securities and Exchange Commission
(the "Commission") are incorporated herein by reference:

     (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 (the
          "Exchange Act") or the latest prospectus filed pursuant to Rule 424(b)

                                       2
Item 5.  Interests of Named Experts and Counsel
------   --------------------------------------

     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

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

     The indemnification provisions in the Registrant's Amended and Restated
Certificate of Incorporation, Bylaws and the Indemnity Agreements entered or 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.

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.

     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,

                                       5
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
