Section 102(b)(7) of the Delaware General Corporation Law (the "DGCL") permits a corporation, in its certificate of incorporation, to limit or eliminate, subject to certain statutory limitations, the liability of directors and officers to the corporation or its stockholders for monetary damages for breaches of fiduciary duty, except for liability (a) for any breach of the director's or officer's duty of loyalty to the corporation or its stockholders, (b) for acts or omissions by a director or officer not in good faith or which involve intentional misconduct or a knowing violation of law, (c) where a director authorized the payment of a dividend or approved a stock repurchase or redemption in violation of Section 174 of the DGCL, (d) for any transaction from which the director or officer derived an improper personal benefit, or (e) with respect to an officer, in any action by or in the right of the corporation. Article Seventh of the Registrant's amended and restated certificate of incorporation provides that the personal liability of the Registrant's directors is eliminated to the fullest extent permitted by the DGCL.

Under Section 145 of the DGCL, a corporation has the power to indemnify directors and officers under certain prescribed circumstances and subject to certain limitations against certain costs and expenses, including attorneys' fees actually and reasonably incurred in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative, to which any of them is a party by reason of being a director or officer of the corporation if it is determined that the director or officer acted in accordance with the applicable standard of conduct set forth in such statutory provision. Article VII of the Company's amended and restated by-laws provides that the Registrant will 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 by reason of the fact that the person is or was a director, officer or other authorized representative of the Registrant, or is or was serving at the request of the Registrant as a director, officer, employee or agent of another entity, against certain liabilities, costs and expenses. Notwithstanding the foregoing, the Registrant is not required to indemnify any person (1) for any action, suit or proceeding initiated by such person, unless the action suit or proceeding was authorized by the Registrant's board of directors; (2) for settlement amounts unless the Registrant consented to the settlement; (3) for judicial awards if the Registrant did not have an opportunity to participate, at its own expense, in the defense of the action, or (4) if the authorized representative has otherwise received payment for the amounts that would have been indemnifiable. Article VII also provides for the advancement of expenses to an indemnified party upon receipt of an undertaking by the party to repay those amounts if it is finally determined that the indemnified party is not entitled to indemnification. Article VII further permits the Registrant to maintain insurance on behalf of any person who is or was a director, officer,

employee or agent of the Registrant, or is or was serving at the request of the Registrant as a director, officer, employee or agent of another entity, against any liability asserted against such person and incurred by such person in any such capacity or arising out of his status as such, whether or not the Registrant would have the power to indemnify such person against such liability under the DGCL. Section 145 also provides that the aforesaid power to indemnify directors and officers may not be impaired by an amendment to the provision after the occurrence of the act or omission that is the subject of an action, suit or proceeding for which indemnification or advancement of expenses is sought, unless the provision in effect at the time of the act or omission explicitly authorizes the impairment.

The Registrant's directors and officers are covered by insurance policies indemnifying them against certain liabilities, including certain liabilities arising under the Securities Act, which might be incurred by them in such capacities and against which they cannot be indemnified by the Registrant.

The Registrant has entered into indemnification agreements (each, an "Indemnification Agreement") with each of its directors and executive officers (each, an "Indemnitee"). Each Indemnification Agreement provides contractual indemnification, expense advancement, and other related rights to the Indemnitees in accordance with the laws of the state of Delaware. The Indemnification Agreements are primarily designed to codify existing protections under the Registrant's articles of incorporation and by-laws and under Delaware law into individual contracts and to provide additional procedural protections for Indemnitees; they do not mandate indemnification of Registrant officials for acts that the Registrant was not previously required to indemnify.

Each Indemnification Agreement obligates the Registrant to indemnify the Indemnitee, to the fullest extent permitted by Delaware law, against all Indemnifiable Claims and Indemnifiable Losses (as those terms are defined in the Indemnification Agreement). Each Indemnification Agreement also provides the Indemnitee with certain rights to advancement of expenses relating to any Indemnifiable Claim paid or incurred, or reasonably likely to be paid or incurred, by the Indemnitee. Further, under each Indemnification Agreement, the Indemnitee is presumed to have satisfied the applicable standard of conduct under Delaware law required for indemnification, and the Registrant may overcome that presumption with clear and convincing evidence to the contrary.

Not applicable.

The following is a list of exhibits filed as part of this Registration Statement.

(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 this 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 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) of the Securities Act 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 this Registration Statement or any material change to such information in this 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 SEC by the Registrant 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 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 that is incorporated by reference in this 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 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.
