</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;102 of the Delaware General Corporation Law allows a corporation to eliminate the
personal liability of directors of a corporation to the corporation or to any of its stockholders
for monetary damage for a breach of his or her fiduciary duty as a director, except in the case
where the director breached his or her duty of loyalty, failed to act in good faith, engaged in
intentional misconduct or knowingly violated a law, authorized the payment of a dividend or
approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal
benefit. The Registrant&#146;s Certificate of Incorporation contains a provision that eliminates
directors&#146; personal liability as set forth above.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the Delaware General Corporation Law, as amended, provides that a corporation
may indemnify any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that he or she is or was a director,
officer, employee or agent of the corporation or is or was serving at its request in such capacity
in another corporation or business association, against expenses (including attorneys&#146; fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in
connection with such action, suit or proceeding if he or she acted in good faith and in a manner he
or she reasonably believed to be in or not opposed to the best interests of the corporation and,
with respect to any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant&#146;s Certificate of Incorporation provides that, to the fullest extent permitted
by the Delaware General Corporation Law, no director of the Company shall be personally liable to
the Company or its stockholders for monetary damages for breach of fiduciary duty as a director.
The Certificate of Incorporation also provides that no amendment or repeal of such provision or
adoption of an inconsistent provision shall apply to or have any effect on the protection from
personal liability to the Company or its stockholders permitted thereunder with respect to any
matter occurring, or any cause of action, suit or claim that, but for the Certificate of
Incorporation, would accrue or arise prior to such amendment, repeal or adoption of an inconsistent
provision. Additionally, the Registrant&#146;s Amended and Restated Bylaws provide that the Registrant
will indemnify to the maximum extent authorized by law each of its directors and officers against
expenses incurred in connection with any proceeding arising by reason of the fact that such person
is or was an agent of the corporation.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant has also obtained on behalf of its officers and directors insurance against
losses arising from any claim asserted against or incurred by such individual in any such capacity,
subject to certain exclusions.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;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; and
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;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 periodic reports filed by the registrant pursuant to Section&nbsp;13 or 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)&nbsp;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.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&nbsp;To remove from registration by means of a post-effective amendment any of the securities

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B.&nbsp;The undersigned registrant hereby undertakes that, for purposes of determining liability
under the Securities Act of 1933, each filing of the registrant&#146;s annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed 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.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C.&nbsp;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.

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 102 of the Delaware General Corporation Law allows a corporation to eliminate the
personal liability of directors of a corporation to the corporation or to any of its stockholders
for monetary damage for a breach of his or her fiduciary duty as a director, except in the case
where the director breached his or her duty of loyalty, failed to act in good faith, engaged in
intentional misconduct or knowingly violated a law, authorized the payment of a dividend or
approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal
benefit. The Registrant's Certificate of Incorporation contains a provision that eliminates
directors' personal liability as set forth above.
Section 145 of the Delaware General Corporation Law, as amended, provides that a corporation
may indemnify any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that he or she is or was a director,
officer, employee or agent of the corporation or is or was serving at its request in such capacity
in another corporation or business association, against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in
connection with such action, suit or proceeding if he or she acted in good faith and in a manner he
or she reasonably believed to be in or not opposed to the best interests of the corporation and,
with respect to any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.
The Registrant's Certificate of Incorporation provides that, to the fullest extent permitted
by the Delaware General Corporation Law, no director of the Company shall be personally liable to
the Company or its stockholders for monetary damages for breach of fiduciary duty as a director.
The Certificate of Incorporation also provides that no amendment or repeal of such provision or
adoption of an inconsistent provision shall apply to or have any effect on the protection from
personal liability to the Company or its stockholders permitted thereunder with respect to any
matter occurring, or any cause of action, suit or claim that, but for the Certificate of
Incorporation, would accrue or arise prior to such amendment, repeal or adoption of an inconsistent
provision. Additionally, the Registrant's Amended and Restated Bylaws provide that the Registrant
will indemnify to the maximum extent authorized by law each of its directors and officers against
expenses incurred in connection with any proceeding arising by reason of the fact that such person
is or was an agent of the corporation.
The Registrant has also obtained on behalf of its officers and directors insurance against
losses arising from any claim asserted against or incurred by such individual in any such capacity,
subject to certain exclusions.

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; and
(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 periodic reports filed by the registrant pursuant to Section 13 or 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 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.
B. The undersigned registrant hereby undertakes that, for purposes of determining liability
under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section
13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed 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 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.
