Item 6. Indemnification of Directors and Officers.

Section 145 (“Section 145”) of the Delaware General Corporation Law (“DGCL”) permits a Delaware corporation to indemnify any person in connection with any suit, action or proceeding, whether civil, criminal, administrative or investigative, to which the person is or is threatened to be made a party by reason of the fact that such person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, or other enterprise, against expenses (including attorneys’ fees), and against judgments, fines, and amounts paid in settlement, other than in actions by or in the right of the corporation, that are actually and reasonably incurred by such person in connection with such action, suit or proceeding, if such person acted in good faith and in a manner that the person reasonably believed to be in or not opposed to the best interest of the corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful; provided, however, that, in the case of actions by or in the right of the corporation, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the adjudicating court determines that indemnification is proper under the circumstances. Under Section 145, a corporation shall indemnify any such person who is successful on the merits or otherwise in defense of any action, suit or proceeding referred to in the Section.

Section 9 of Article III of the Registrant’s by-laws provides that the Registrant must indemnify its current and former directors and officers to the fullest extent permitted by Delaware law and, as permitted by Section 145, requires the Registrant to advance expenses incurred in defending a suit, action or proceeding, whether civil or criminal, to the extent authorized by the Registrant’s Board of Directors upon receipt of an undertaking by a director or officer to repay such expenses if it is determined that such director or officer is not entitled to indemnification.

The Registrant’s certificate of incorporation, in Article Thirteenth, paragraph (b), provides that no director of the Registrant shall be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director. This provision does not eliminate the liability of a director of the Registrant (1) for any breach of a director’s duty of loyalty to the Registrant or its stockholders; (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law; (3) under Section 174 of the DGCL; or (4) for any transaction in which a director derived improper personal benefit.

The indemnification provisions in the Registrant’s by-laws and certificate of incorporation are not exclusive of any other rights to which those indemnified thereunder may be entitled to by law, agreement, vote of stockholders or otherwise.

The Registrant has entered into agreements to indemnify its non-employee directors (each an “Indemnified Representative”) in addition to the indemnification provided for in the Registrant’s certificate of incorporation and by-laws. Under these agreements, the Registrant will, among other things, indemnify each Indemnified Representative against certain expenses (including attorneys’ fees and expenses), judgments, settlement amounts, or fines incurred by or assessed against an Indemnified Representative in any threatened, pending or completed action or proceeding, including those by or in the right of the Registrant, by reason of the fact that the Indemnified Representative is or was serving the Registrant as a director, officer, employee or agent of the Registrant, or, at the request of the Registrant, as a director, officer, employee, agent, fiduciary, or in a similar capacity for another corporation, joint venture, trust, employee benefit plan or other entity.

3

In addition, the Registrant maintains liability insurance providing coverage per policy year (with certain deductibles and exceptions) for past, present and future directors and officers of the Registrant acting in such capacities.

Item 7. Exemption from Registration Claimed.

Not applicable.

24.1 Power of Attorney

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;

(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 a 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 Exchange Act that are incorporated by reference in the 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 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 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

5

otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of such issue.
