<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;317 of the California General Corporation Law provides that a corporation may
indemnify corporate &#147;agents&#148; (including directors, officers and employees of the corporation)
against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred
in connection with defending non-derivative actions if such person acted in good faith and in a
manner such person reasonably believed to be in the best interests of the corporation and, in the
case of a criminal proceeding, had no reasonable cause to believe the conduct of such person was
unlawful, and against expenses actually and reasonably incurred in connection with defending
derivative actions if such person acted in good faith and in a manner such person believed to be in
the best interests of the corporation and its shareholders. Indemnification is obligatory to the
extent that an agent of a corporation has been successful on the merits in defense of any such
proceeding against such agent, but otherwise may be made only upon a determination in each instance
either by a majority vote of a quorum of the Board of Directors (other than directors involved in
such proceeding), by independent legal counsel if such a quorum of directors is not obtainable, by
the shareholders (other than shareholders to be indemnified), or by the court, that indemnification
is proper because the agent has met the applicable statutory standards of conduct. Corporations
may also advance expenses incurred in defending proceedings against corporate agents, upon receipt
of an undertaking that the agent will reimburse the corporation unless it is ultimately determined

on such excess indemnification set forth in Section&nbsp;204 of the California General Corporation Law.

Securities and Exchange Commission such indemnification is against public policy as expressed in
the Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such

Item 4. Description of Securities.
Not Applicable.
Item 5. Interests of Named Experts and Counsel.
Not Applicable.
Item 6. Indemnification of Directors and Officers.
Section 317 of the California General Corporation Law provides that a corporation may
indemnify corporate "agents" (including directors, officers and employees of the corporation)
against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred
in connection with defending non-derivative actions if such person acted in good faith and in a
manner such person reasonably believed to be in the best interests of the corporation and, in the
case of a criminal proceeding, had no reasonable cause to believe the conduct of such person was
unlawful, and against expenses actually and reasonably incurred in connection with defending
derivative actions if such person acted in good faith and in a manner such person believed to be in
the best interests of the corporation and its shareholders. Indemnification is obligatory to the
extent that an agent of a corporation has been successful on the merits in defense of any such
proceeding against such agent, but otherwise may be made only upon a determination in each instance
either by a majority vote of a quorum of the Board of Directors (other than directors involved in
such proceeding), by independent legal counsel if such a quorum of directors is not obtainable, by
the shareholders (other than shareholders to be indemnified), or by the court, that indemnification
is proper because the agent has met the applicable statutory standards of conduct. Corporations
may also advance expenses incurred in defending proceedings against corporate agents, upon receipt
of an undertaking that the agent will reimburse the corporation unless it is ultimately determined
that the agent is entitled to be indemnified against expenses reasonably incurred.
The indemnification provided by Section 317 of the California General Corporation Law is not
deemed to be exclusive of any other rights to which agents of a corporation seeking indemnification
may be entitled under any bylaw, agreement, vote of shareholders or disinterested directors, or
otherwise, both as to action in an official capacity and as to action in another capacity while
holding such office, to the extent such additional rights are authorized in the articles of the
corporation. Article V of the Registrant's Amended and Restated Articles of Incorporation
authorizes the Registrant to provide for indemnification of its agents for breach of duty to the
Registrant and its shareholders, through bylaw provisions or through agreements with such agents,
or both, in excess of the indemnification otherwise permitted by Section 317, subject to the limits
on such excess indemnification set forth in Section 204 of the California General Corporation Law.
Article VI of the Registrant's Amended and Restated Bylaws, as amended (the "Amended and
Restated Bylaws"), provides for the mandatory indemnification of all directors and executive
officers of the Registrant to the maximum extent and in the manner permitted by Section 317.
Additionally, the Registrant has entered into indemnification agreements with its directors and
executive officers under which the Registrant has undertaken to indemnify each such director or
executive officer to the fullest extent permitted by its Amended and Restated Articles of
2
Incorporation, Amended and Restated Bylaws and applicable law against all expenses, liability
and loss (which are not paid by insurance or otherwise by the Registrant) reasonably incurred or
suffered by such agent in connection with the defense of any action or proceeding to which the
agent was or is a party or is threatened to be made a party by reason of conduct in his capacity as
an officer or director, or in which the agent is or may be involved by reason of the fact that he
is or was serving as an officer or director of the Registrant. These indemnification agreements do
not require the Registrant to:
•
indemnify any director or executive officer where such indemnification for any
acts or omissions or transactions would be in violation of the California General
Corporation Law or other applicable law, including without limitation
imdemnification for breach of duty to the corporation or its shareholders under
circumstances in which such indemnity would be expressly prohibited by Section 317
of the California General Corporation Law;
•
indemnify or advance expenses to any director or executive officer with respect
to claims voluntarily initiated by such director or executive officer and not by
way of defense, other than with respect to claims brought in order to enforce the
indemnification agreement itself or a right under Section 317 of the California
General Corporation Law, or other applicable law, unless such claim has been
approved by the Registrant;
•
indemnify any director or executive officer for any expenses incurred with
respect to claims brought to enforce the indemnification agreement itself or a
right under Section 317 of the California General Corporation Law, or other
applicable law, which claim was determined by a court of competent jurisdiction to
be frivolous or not in good faith;
•
indemnify any director or executive officer for any expenses for which such
director or executive officer has otherwise received payment pursuant to a
liability insurance policy, the Registrant's Amended and Restated Articles of
Incorporation or Amended and Restated Bylaws, any applicable provisions of the
California General Corporation Law, or any other agreement; or
•
indemnify any director or executive officer for expenses or profits arising from
the purchase and sale by such director or executive officer of securities in
violation of Section 16(b) of the Exchange Act.
The Registrant also maintains on behalf of its directors and officers insurance protection
against certain liabilities arising out of the discharge of their duties.

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 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;
provided
,
however
, that 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 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 (a)(1)(i) and (a)(1)(ii) do not apply if
the information required to be included in a post-effective amendment by those paragraphs is
contained in 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 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
4
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.
(4) That, for the purpose of determining liability of the Registrant under the Securities Act
of 1933 to any purchaser in the initial distribution of the securities, the undersigned Registrant
undertakes that in a primary offering of securities of the undersigned Registrant pursuant to the
registration statement, regardless of the underwriting method used to sell the securities to the
purchaser, if the securities are offered or sold to such purchaser by means of any of the following
communications, the undersigned Registrant will be a seller to the purchaser and will be considered
to offer or sell such securities to such purchaser: (i) any preliminary prospectus or prospectus of
the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;
(ii) any free writing prospectus relating to the offering prepared by or on behalf of the
undersigned Registrant or used or referred to by the undersigned Registrant; (iii) the portion of
any other free writing prospectus relating to the offering containing material information about
the undersigned Registrant or its securities provided by or on behalf of the undersigned
Registrant; and (iv) any other communication that is an offer in the offering made by the
undersigned Registrant to the purchaser.
(b) 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 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.
(c) 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 Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such
issue.
