Item 5.  Interests of Named Experts and Counsel.

     The validity of the Common Stock will be passed upon for the Registrant by
Manatt, Phelps & Phillips, LLP, Palo Alto, California.

Item 6. Indemnification of Directors and Officers.

     As permitted by Section 145 of the Delaware General Corporation Law, the
Registrant's Certificate of Incorporation includes a provision that eliminates
the personal liability of its directors to the Registrant or its stockholders
for 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 that involve intentional misconduct or a knowing violation of law,
(iii) under section 174 of the Delaware General

                                      2

<PAGE>

Corporation Law or (iv) for any transaction from which the director derived
an improper personal benefit. In addition, as permitted by Section 145 of the
Delaware General Corporation Law, the Certificate of Incorporation of the
Registrant provides that: (i) the Registrant is required to indemnify its
directors and officers to the fullest extent permitted by the Delaware General
Corporation Law; (ii) the Registrant may, in its discretion, indemnify other
officers, employees and agents as set forth in the Delaware General Corporation
Law; (iii) upon receipt of an undertaking to repay such advances if
indemnification is determined to be unavailable, the Registrant is required to
advance expenses, as incurred, to its directors and executive officers in
connection with a proceeding; (iv) the rights conferred in the Certificate of
Incorporation are not exclusive and the Registrant is authorized to enter into
indemnification agreements with its directors, officers, employees and agents;
(v) the Registrant may not retroactively apply any amendment of the Certificate
of Incorporation provisions relating to indemnity; and (vi) to the fullest
extent permitted by the Delaware General Corporation Law, a director or
executive officer will be deemed to have acted in good faith if his or her
action is based on the records or books of account of the Registrant or on
information supplied to him or her by officers of the Registrant in the course
of their duties or on the advice of legal counsel for the Registrant or on
information or records given or reports made to the Registrant by independent
certified public accountants or appraisers or other experts.

     The indemnification provision in the Certificate of Incorporation may be
sufficiently broad to permit indemnification of the Registrant's directors and
executive officers for liabilities arising under the Securities Act.

     As approved by the Registrant's Board of Directors, the Registrant
maintains director and officer liability insurance.

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 Securities Act of 1933;

               (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. 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 and 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;

     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,

                                      3

<PAGE>

however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(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 Securities Exchange Act of 1934 that are
incorporated by reference in this 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; 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 Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in 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)  The undersigned Registrant hereby undertakes to deliver or cause to
be delivered with the prospectus, to each person to whom the prospectus is sent
or given, the latest annual report, to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

     (d)  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 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, 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.

     Not applicable

Item 5.  Interests of Named Experts and Counsel.

     The validity of the Common Stock will be passed upon for the Registrant by
Manatt, Phelps & Phillips, LLP, Palo Alto, California.

Item 6. Indemnification of Directors and Officers.

     As permitted by Section 145 of the Delaware General Corporation Law, the
Registrant's Certificate of Incorporation includes a provision that eliminates
the personal liability of its directors to the Registrant or its stockholders
for 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 that involve intentional misconduct or a knowing violation of law,
(iii) under section 174 of the Delaware General

                                      2
Corporation Law or (iv) for any transaction from which the director derived
an improper personal benefit. In addition, as permitted by Section 145 of the
Delaware General Corporation Law, the Certificate of Incorporation of the
Registrant provides that: (i) the Registrant is required to indemnify its
directors and officers to the fullest extent permitted by the Delaware General
Corporation Law; (ii) the Registrant may, in its discretion, indemnify other
officers, employees and agents as set forth in the Delaware General Corporation
Law; (iii) upon receipt of an undertaking to repay such advances if
indemnification is determined to be unavailable, the Registrant is required to
advance expenses, as incurred, to its directors and executive officers in
connection with a proceeding; (iv) the rights conferred in the Certificate of
Incorporation are not exclusive and the Registrant is authorized to enter into
indemnification agreements with its directors, officers, employees and agents;
(v) the Registrant may not retroactively apply any amendment of the Certificate
of Incorporation provisions relating to indemnity; and (vi) to the fullest
extent permitted by the Delaware General Corporation Law, a director or
executive officer will be deemed to have acted in good faith if his or her
action is based on the records or books of account of the Registrant or on
information supplied to him or her by officers of the Registrant in the course
of their duties or on the advice of legal counsel for the Registrant or on
information or records given or reports made to the Registrant by independent
certified public accountants or appraisers or other experts.

     The indemnification provision in the Certificate of Incorporation may be
sufficiently broad to permit indemnification of the Registrant's directors and
executive officers for liabilities arising under the Securities Act.

     As approved by the Registrant's Board of Directors, the Registrant
maintains director and officer liability insurance.

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 Securities Act of 1933;

               (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. 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 and 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;

     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,

                                      3
however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(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 Securities Exchange Act of 1934 that are
incorporated by reference in this 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; 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 Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in 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)  The undersigned Registrant hereby undertakes to deliver or cause to
be delivered with the prospectus, to each person to whom the prospectus is sent
or given, the latest annual report, to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

     (d)  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 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, 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.
