</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 (the &#147;DGCL&#148;) provides, in summary, that
directors and officers of Delaware corporations are entitled, under certain circumstances, to be
indemnified against all expenses and liabilities (including attorneys&#146; fees) incurred by them as a
result of suits brought against them in their capacity as directors or officers if they acted in
good faith and in a manner they reasonably believed to be in or not opposed to the Company&#146;s best
interests and, with respect to any criminal action or proceeding, if they had no reasonable cause
to believe their conduct was unlawful; provided that no indemnification may be made against
expenses in respect of any claim, issue, or matter as to which they shall have been adjudged to be
liable to us, unless and only to the extent that the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability but in view of all the
circumstances of the case, they are fairly and reasonably entitled to indemnity for such expenses
as the court shall deem proper. Any such indemnification may be made by us only as authorized in
each specific case upon a determination by the stockholders, disinterested directors, or
independent legal counsel that indemnification is proper because the indemnitee has met the
applicable standard of conduct.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;102(b)(7) of the DGCL permits a corporation to provide in its certificate of
incorporation that a director of the corporation shall not be personally liable to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a director except for
liability for any breach of the director&#146;s duty of loyalty to the corporation or its stockholders,
for acts or omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, for unlawful payments of dividends or unlawful stock repurchases, redemptions, or
other distributions or 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 Company&#146;s amended and restated certificate of incorporation and amended and restated
by-laws provide that the Company shall indemnify its directors and officers to the fullest extent
permitted by law and that no director shall be liable for monetary damages to the Company or its
stockholders for any breach of fiduciary duty, except to the extent provided by applicable law. The
Company has entered into indemnification agreements with its directors. The indemnification
agreements provide indemnification to the Company&#146;s directors under certain circumstances for acts
or omissions that may not be covered by directors&#146; and officers&#146; liability insurance and may, in
some cases, be broader than the specific indemnification provisions contained under Delaware law.
The Company currently maintains liability insurance for its directors and officers.

<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;(i)&nbsp;To include any prospectus required by Section&nbsp;10(a)(3) of the Securities Act;
</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;(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. 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 a 20&nbsp;percent change in the
maximum aggregate offering price set forth in the &#147;Calculation of Registration Fee&#148; table in the
effective 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;
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Provided, however</I>, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if
the registration statement is on Form S-8, and 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 Company pursuant to Section&nbsp;13 or Section 15(d) of the Exchange Act that are
incorporated by reference in this 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, 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 <I>bona fide </I>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
being registered which remain unsold at the termination of the offering.</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;The undersigned Company hereby undertakes that, for purposes of determining any liability
under the Securities Act, each filing of the Company&#146;s annual report pursuant to Section 13(a) or
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 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 Company pursuant to the foregoing
provisions, or otherwise, the Company has been advised that in the opinion of the 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 Company of expenses incurred or paid by a director, officer, or controlling
person of the
Company 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
Company 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 3. Incorporation of Documents by Reference
The following documents, filed by the Company with the Securities and Exchange Commission (the

incorporated herein by reference and deemed to be a part hereof:
(a) The Company's Annual Report on Form 10-K for the year ended December 31, 2009;
(b) All other reports filed by the Company pursuant to Section 13(a) or 15(d) of the Exchange
Act since December 31, 2009;
(c) The description of the Company's Common Stock that is contained in the Company's
Registration Statement on Form 8-A filed with the Commission on June 14, 2005 (File No. 333-122788)
under the Exchange Act, including any amendment or report filed for the purpose of updating such

Registration Statement that indicates that all securities offered have been sold or that

Any statement contained in a document incorporated or deemed incorporated herein by reference
shall be deemed to be modified or superseded for the purpose of this Registration Statement to the
extent that a statement contained herein or in any subsequently filed document that also is, or is
deemed to be, incorporated herein by reference modifies or supersedes such statement. Any such
statement so modified or superseded shall not be deemed, except as so modified or superseded, to
constitute a part of this Registration Statement.
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 145 of the Delaware General Corporation Law (the "DGCL") provides, in summary, that
directors and officers of Delaware corporations are entitled, under certain circumstances, to be
indemnified against all expenses and liabilities (including attorneys' fees) incurred by them as a
result of suits brought against them in their capacity as directors or officers if they acted in
good faith and in a manner they reasonably believed to be in or not opposed to the Company's best
interests and, with respect to any criminal action or proceeding, if they had no reasonable cause
to believe their conduct was unlawful; provided that no indemnification may be made against
expenses in respect of any claim, issue, or matter as to which they shall have been adjudged to be
liable to us, unless and only to the extent that the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability but in view of all the
circumstances of the case, they are fairly and reasonably entitled to indemnity for such expenses
as the court shall deem proper. Any such indemnification may be made by us only as authorized in
each specific case upon a determination by the stockholders, disinterested directors, or
independent legal counsel that indemnification is proper because the indemnitee has met the
applicable standard of conduct.
Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of
incorporation that a director of the corporation shall not be personally liable to the corporation
or its stockholders for monetary damages for breach of fiduciary duty as a director except for
liability for any breach of the director's duty of loyalty to the corporation or its stockholders,
for acts or omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, for unlawful payments of dividends or unlawful stock repurchases, redemptions, or
other distributions or for any transaction from which the director derived an improper personal
benefit.
The Company's amended and restated certificate of incorporation and amended and restated
by-laws provide that the Company shall indemnify its directors and officers to the fullest extent
permitted by law and that no director shall be liable for monetary damages to the Company or its
stockholders for any breach of fiduciary duty, except to the extent provided by applicable law. The
Company has entered into indemnification agreements with its directors. The indemnification
agreements provide indemnification to the Company's directors under certain circumstances for acts
or omissions that may not be covered by directors' and officers' liability insurance and may, in
some cases, be broader than the specific indemnification provisions contained under Delaware law.
The Company currently maintains liability insurance for its directors and officers.
Item 7. Exemption from Registration Claimed
Not applicable.
Item 8. Exhibits
See the Exhibit Index, which is incorporated herein by reference.

Item 9. Undertakings
(a) The undersigned Company 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 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) 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; 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) of this section do not apply if
the registration statement is on Form S-8, and 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 Company pursuant to Section 13 or Section 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) The undersigned Company hereby undertakes that, for purposes of determining any liability
under the Securities Act, each filing of the Company's annual report pursuant to Section 13(a) or
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 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 Company pursuant to the foregoing
provisions, or otherwise, the Company has been advised that in the opinion of the 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 Company of expenses incurred or paid by a director, officer, or controlling
person of the
Company 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
Company 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.
