<DIV align="left"><A NAME="002"></A></DIV>

<P align="center" style="font-size: 10pt"><B>INDEMNIFICATION OF DIRECTORS AND OFFICERS</B>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under Section&nbsp;145 of the Delaware General Corporation Law, the Registrant
has broad powers to indemnify its directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant&#146;s Amended and Restated Certificate of Incorporation and
Amended and Restated Bylaws include provisions to (i)&nbsp;eliminate the personal
liability of its directors for monetary damages resulting from breaches of
their fiduciary duty to the extent permitted by Section&nbsp;102(b)(7) of the
General Corporation Law of Delaware (the &#147;Delaware Law&#148;) and (ii)&nbsp;require the
Registrant to indemnify its directors and executive officers to the fullest
extent permitted by Section&nbsp;145 of the Delaware Law, including circumstances in
which indemnification is otherwise discretionary. Pursuant to Section&nbsp;145 of
the Delaware Law, a corporation generally has the power to indemnify its
present and former directors, officers, employees and agents against expenses
incurred by them in connection with any suit to which they are, or are
threatened to be made, a party by reason of their serving in such positions so
long as they acted in good faith and in a manner they reasonably believed to be
in or not opposed to, the best interests of the corporation and with respect to
any criminal action, they had no reasonable cause to believe their conduct was
unlawful. The Registrant believes that these provisions are necessary to
attract and retain qualified persons as directors and officers. These
provisions do not eliminate the directors&#146; duty of care, and, in appropriate
circumstances, equitable remedies such as injunctive or other forms of
non-monetary relief will remain available under Delaware Law. In addition, each
director will continue to be subject to liability for breach of the director&#146;s
duty of loyalty to the Registrant, for acts or omissions not in good faith or
involving intentional misconduct, for knowing violations of law, for acts or
omissions that the director believes to be contrary to the best interests of
the Registrant or its stockholders, for any transaction from which the director
derived an improper personal benefit, for acts or omissions involving a
reckless disregard for the director&#146;s duty to the Registrant or its
stockholders when the director was aware or should have been aware of a risk of
serious injury to the Registrant or its stockholders, for acts or omissions
that constitute an unexcused pattern of inattention that amounts to an
abdication of the director&#146;s duty to the Registrant or its stockholders, for
improper transactions between the director and the Registrant and for improper
distributions to stockholders and loans to directors and officers.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The provisions also do not affect a director&#146;s responsibilities under any
other law, such as the federal securities laws or state or federal
environmental laws.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant&#146;s policy is to enter into separate indemnification
agreements with each of its directors and executive officers that contain
indemnification provisions that may be broader than the specific
indemnification provisions contained in the Delaware Law. These indemnification
agreements may require the Registrant, among other things, to indemnify its
directors and executive officers for some expenses, including attorneys&#146; fees,

<P align="left" style="font-size: 10pt">judgments, fines and settlement amounts incurred by a director or executive
officer in any action or proceeding arising out of his service as a director,
officer, employee or other agent of the Registrant or any of its subsidiaries
or any other company or enterprise to which the person provides services at the
Registrant&#146;s request. The form of these indemnification agreements is filed as
Exhibit&nbsp;10.7 to the Form S-1.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Amended and Restated Investor Rights Agreement, dated October&nbsp;2, 2001,
among the Registrant and certain holders of the Registrant&#146;s securities
provides for cross-indemnification in connection with registration of the
Registrant&#146;s common stock held by such holders. The Amended and Restated
Investor Rights Agreement is filed as Exhibit&nbsp;10.1 to the Form S-1.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;At present, there is no pending litigation or proceeding involving a
director or officer of the Registrant as to which indemnification is being
sought nor is the Registrant aware of any threatened litigation that may result
in claims for indemnification by any officer or director.

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) (&#167; 230.424(b) of this
chapter) if, in the aggregate, the changes in volume and price represent no
more than a 20% change in the maximum aggregate offering price set forth in the

statement.

registrant has been advised that in the opinion of the Securities and

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, 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
Securities Act and will be governed by the final adjudication of such
issue.</TD>

(c)

reports and documents.
INTERESTS OF NAMED EXPERTS AND COUNSEL
The validity of the issuance of the common stock offered by this
prospectus and certain other legal matters are being passed upon for us by our
counsel, Cooley Godward LLP, Palo Alto, California. As of the date of this
prospectus, Cooley Godward LLP beneficially owned 45,833 shares of our common
stock.
INDEMNIFICATION OF DIRECTORS AND OFFICERS
Under Section 145 of the Delaware General Corporation Law, the Registrant
has broad powers to indemnify its directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act.
The Registrant's Amended and Restated Certificate of Incorporation and
Amended and Restated Bylaws include provisions to (i) eliminate the personal
liability of its directors for monetary damages resulting from breaches of
their fiduciary duty to the extent permitted by Section 102(b)(7) of the
General Corporation Law of Delaware (the "Delaware Law") and (ii) require the
Registrant to indemnify its directors and executive officers to the fullest
extent permitted by Section 145 of the Delaware Law, including circumstances in
which indemnification is otherwise discretionary. Pursuant to Section 145 of
the Delaware Law, a corporation generally has the power to indemnify its
present and former directors, officers, employees and agents against expenses
incurred by them in connection with any suit to which they are, or are
threatened to be made, a party by reason of their serving in such positions so
long as they acted in good faith and in a manner they reasonably believed to be
in or not opposed to, the best interests of the corporation and with respect to
any criminal action, they had no reasonable cause to believe their conduct was
unlawful. The Registrant believes that these provisions are necessary to
attract and retain qualified persons as directors and officers. These
provisions do not eliminate the directors' duty of care, and, in appropriate
circumstances, equitable remedies such as injunctive or other forms of
non-monetary relief will remain available under Delaware Law. In addition, each
director will continue to be subject to liability for breach of the director's
duty of loyalty to the Registrant, for acts or omissions not in good faith or
involving intentional misconduct, for knowing violations of law, for acts or
omissions that the director believes to be contrary to the best interests of
the Registrant or its stockholders, for any transaction from which the director
derived an improper personal benefit, for acts or omissions involving a
reckless disregard for the director's duty to the Registrant or its
stockholders when the director was aware or should have been aware of a risk of
serious injury to the Registrant or its stockholders, for acts or omissions
that constitute an unexcused pattern of inattention that amounts to an
abdication of the director's duty to the Registrant or its stockholders, for
improper transactions between the director and the Registrant and for improper
distributions to stockholders and loans to directors and officers.
The provisions also do not affect a director's responsibilities under any
other law, such as the federal securities laws or state or federal
environmental laws.
The Registrant's policy is to enter into separate indemnification
agreements with each of its directors and executive officers that contain
indemnification provisions that may be broader than the specific
indemnification provisions contained in the Delaware Law. These indemnification
agreements may require the Registrant, among other things, to indemnify its
directors and executive officers for some expenses, including attorneys' fees,
3.
Table of Contents
judgments, fines and settlement amounts incurred by a director or executive
officer in any action or proceeding arising out of his service as a director,
officer, employee or other agent of the Registrant or any of its subsidiaries
or any other company or enterprise to which the person provides services at the
Registrant's request. The form of these indemnification agreements is filed as
Exhibit 10.7 to the Form S-1.
The Amended and Restated Investor Rights Agreement, dated October 2, 2001,
among the Registrant and certain holders of the Registrant's securities
provides for cross-indemnification in connection with registration of the
Registrant's common stock held by such holders. The Amended and Restated
Investor Rights Agreement is filed as Exhibit 10.1 to the Form S-1.
At present, there is no pending litigation or proceeding involving a
director or officer of the Registrant as to which indemnification is being
sought nor is the Registrant aware of any threatened litigation that may result
in claims for indemnification by any officer or director.

UNDERTAKINGS
1.
The undersigned registrant hereby undertakes:
(a)
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) (§ 230.424(b) of this
chapter) if, in the aggregate, the changes in volume and price represent no
more than a 20% 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 (a)(i) and (a)(ii) 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 issuer pursuant to
section 13 or section 15(d) of the Exchange Act that are incorporated by
reference herein.
5.
Table of Contents
(b)
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 herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
(c)
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.
2.
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 herein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
3.
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 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 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, 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
Securities Act and will be governed by the final adjudication of such
issue.
