<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The General Corporation Law of the State of Delaware (the &#147;DGCL&#148;) permits the Registrant and
its stockholders to limit directors&#146; exposure to liability for certain breaches of the directors&#146;
fiduciary duty, either in a lawsuit on behalf of the Registrant or in an action by stockholders of
the Registrant. The Restated Certificate of Incorporation of the Registrant provides that a
director of the Registrant shall not be personally liable to the Registrant or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for liability (i)&nbsp;for any
breach of the director&#146;s duty of loyalty to the Registrant or its stockholders, (ii)&nbsp;for acts or
omissions not in good faith or which involve intentional misconduct or a knowing violation of law,
(iii)&nbsp;under Section&nbsp;174 of the DGCL or (iv)&nbsp;for any transaction from which the director derived an
improper personal benefit.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Amended and Restated Bylaws (the &#147;Bylaws&#148;) of the Registrant provide that the Registrant
shall, to the full extent permitted by applicable laws (including the DGCL), indemnify its
directors, officers, employees and agents with respect to expenses (including counsel fees),
judgments, fines, penalties, other liabilities and amounts incurred by any such person in
connection with any threatened, pending or completed action, suit or proceeding to which such
person is or was a party, or is or was threatened to be made a party, by reason of the fact that
such person is or was serving as a director, officer, employee or agent of the Registrant or any of
its subsidiaries, or is or was serving at the request of the Registrant or any of its subsidiaries
as a director, officer, employee, agent or trustee of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise. The Bylaws provide that the
indemnification provided pursuant to the Bylaws is not exclusive of any other rights to which those
seeking indemnification may be entitled under any provision of law, certificate of incorporation,
bylaws, governing documents, agreement, vote of stockholders or disinterested directors or
otherwise. The Registrant has entered into indemnification agreements with certain of its officers
and directors, under which the Registrant has agreed to indemnify its officers and directors
against certain liabilities.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant maintains a standard form of officers&#146; and directors&#146; liability insurance
policy which provides coverage to the officers and directors of the Registrant for certain
liabilities, including certain liabilities which may arise out of this Registration Statement.

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 SEC 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.

Item 5. Interests of Named Experts and Counsel.

Item 6. Indemnification of Directors and Officers.
The General Corporation Law of the State of Delaware (the "DGCL") permits the Registrant and
its stockholders to limit directors' exposure to liability for certain breaches of the directors'
fiduciary duty, either in a lawsuit on behalf of the Registrant or in an action by stockholders of
the Registrant. The Restated Certificate of Incorporation of the Registrant provides that a
director of the Registrant shall not be personally liable 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 Registrant or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the DGCL or (iv) for any transaction from which the director derived an
improper personal benefit.
The Amended and Restated Bylaws (the "Bylaws") of the Registrant provide that the Registrant
shall, to the full extent permitted by applicable laws (including the DGCL), indemnify its
directors, officers, employees and agents with respect to expenses (including counsel fees),
judgments, fines, penalties, other liabilities and amounts incurred by any such person in
connection with any threatened, pending or completed action, suit or proceeding to which such
person is or was a party, or is or was threatened to be made a party, by reason of the fact that
such person is or was serving as a director, officer, employee or agent of the Registrant or any of
its subsidiaries, or is or was serving at the request of the Registrant or any of its subsidiaries
as a director, officer, employee, agent or trustee of another corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise. The Bylaws provide that the
indemnification provided pursuant to the Bylaws is not exclusive of any other rights to which those
seeking indemnification may be entitled under any provision of law, certificate of incorporation,

Item 9. Undertakings.
A. Undertaking to update.
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;
(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 hereof) 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 end of the estimated maximum offering
range may be reflected in the form of prospectus filed with the SEC 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
this Registration Statement; and
(iii) 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
,
however
, that paragraphs (i) and (ii) above 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 SEC by the Registrant pursuant to Section 13
or 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.
(2) 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 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. Filings incorporating subsequent Exchange Act documents by reference.
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 15(d) of the Exchange Act that is incorporated by reference in this
-3-
Table of Contents
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.
C. Undertaking with respect to indemnification.
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 SEC 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.
