<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 that a corporation
may indemnify directors and officers as well as other employees and agents of the corporation
against expenses (including attorneys&#146; fees), judgments, fines, and amounts paid in settlement in
connection with specified actions, suits or proceedings, whether civil, criminal, administrative,
or investigative (other than action by or in the right of the corporation &#150; a &#147;derivative action&#148;),
if 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 or proceeding, had no
reasonable cause to believe their conduct was unlawful. A similar standard is applicable in the
case of derivative actions, except that indemnification only extends to expenses (including
attorneys&#146; fees) incurred in connection with the defense or settlement of such action, and the DGCL
requires court approval before there can be any indemnification where the person seeking
indemnification has been found liable to the corporation. The DGCL provides that it is not
exclusive of other indemnification that may be granted by a corporation&#146;s charter, by-laws,
disinterested director vote, stockholder vote, agreement, or otherwise.

a partnership, joint venture, trust or other enterprise, including service with respect to an
employee benefit plan, will be indemnified by the Company to the full extent permitted by the DGCL

opposed to the best interests of the Company. The indemnification rights conferred by the Company&#146;s
By-laws are not exclusive of any other right to which such person seeking indemnification may be

liability for (i)&nbsp;any breach of the director&#146;s duty of loyalty to the corporation or its
stockholders, (ii)&nbsp;acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii)&nbsp;payment of unlawful dividends or unlawful stock purchases or

fiduciary duty as a director.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;145 of the DGCL provides, in general, that a corporation may purchase and maintain
insurance on behalf of any person who is or was a director or officer of the corporation against
any liability asserted against the person in any such capacity, or arising out of the person&#146;s
status as such, whether or not the corporation would have the power to indemnify the person against
such liability under the provisions of the law.

Company and its subsidiaries, of certain losses of such persons (other than matters uninsurable
under law) arising from claims, including claims arising under the Securities Act, for acts or

Item 4. Description of Securities
Not Applicable.
Item 5. Interests of Named Experts and Counsel
The legality of the securities offered hereby will be passed upon by Laureen E. Seeger,
Executive Vice President, General Counsel and Secretary of the Registrant. Ms. Seeger owns,
directly and indirectly, less than 1% of the outstanding shares of the Registrant's Common Stock.
Item 6. Indemnification of Directors and Officers
Section 145 of the Delaware General Corporation Law (the "DGCL") provides that a corporation
may indemnify directors and officers as well as other employees and agents of the corporation
against expenses (including attorneys' fees), judgments, fines, and amounts paid in settlement in
connection with specified actions, suits or proceedings, whether civil, criminal, administrative,
or investigative (other than action by or in the right of the corporation – a "derivative action"),
if 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 or proceeding, had no
reasonable cause to believe their conduct was unlawful. A similar standard is applicable in the
case of derivative actions, except that indemnification only extends to expenses (including
attorneys' fees) incurred in connection with the defense or settlement of such action, and the DGCL
requires court approval before there can be any indemnification where the person seeking
indemnification has been found liable to the corporation. The DGCL provides that it is not
exclusive of other indemnification that may be granted by a corporation's charter, by-laws,
disinterested director vote, stockholder vote, agreement, or otherwise.
The Company's Amended and Restated By-laws provide that each person who is involved in any
actual or threatened action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he or she is or was a director or officer of the Company,
or is or was serving at the
Table of Contents
request of the Company as a director, officer, employee or agent of another corporation or of
a partnership, joint venture, trust or other enterprise, including service with respect to an
employee benefit plan, will be indemnified by the Company to the full extent permitted by the DGCL
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 Company. The indemnification rights conferred by the Company's
By-laws are not exclusive of any other right to which such person seeking indemnification may be
entitled under any law, by-law, agreement, vote of stockholders or disinterested directors or
otherwise.
Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of
incorporation that a director of the corporation will 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 (i) any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) payment of unlawful dividends or unlawful stock purchases or
redemptions, or (iv) any transaction from which the director derived an improper personal benefit.
Article VI of the Company's Amended and Restated Certificate of Incorporation provides that to the full
extent permitted by the DGCL, as it now exists or may hereafter be amended, no director of the
Company will be liable to the Company or its stockholders for monetary damages for breach of
fiduciary duty as a director.
Section 145 of the DGCL provides, in general, that a corporation may purchase and maintain
insurance on behalf of any person who is or was a director or officer of the corporation against
any liability asserted against the person in any such capacity, or arising out of the person's
status as such, whether or not the corporation would have the power to indemnify the person against
such liability under the provisions of the law.
As permitted by Section 145 of the DGCL, the Company maintains directors' and officers'
liability insurance which provides for payment, on behalf of the directors and officers of the
Company and its subsidiaries, of certain losses of such persons (other than matters uninsurable
under law) arising from claims, including claims arising under the Securities Act, for acts or
omissions by such persons while acting as directors or officers of the Company and/or its
subsidiaries, as the case may be.

Item 9. 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) 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.
(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 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 periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that
are incorporated by reference in the Registration Statement.
(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.
Table of Contents
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 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.
