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”) grants the Registrant the power to indemnify each 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, whether civil, criminal, administrative or investigative by reason of the fact that the person 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 enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with any such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Registrant, and with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful, provided, however, no indemnification shall

be made in connection with any proceeding brought by or in the right of the Registrant where the person involved is adjudged to be liable to the Registrant except to the extent approved by a court.

The Registrant’s Amended and Restated Certificate of Incorporation (“Certificate of Incorporation”) and Third Amended and Restated Bylaws (“Bylaws”) provide that the Registrant will indemnify and hold harmless to the fullest extent permitted by the DCGL, as amended from time to time, any person who is made a party or is threatened to be made a party to any action, suit or proceeding because such person is or was a director or officer of the Registrant, or at the Registrant’s request, a director, officer, employee or agent of another enterprise. The Registrant’s Certificate of Incorporation and Bylaws also provide that the right to indemnification includes the right to be paid the expenses incurred in defending any such proceeding in advance of its final disposition, subject to limited exceptions. Indemnification under the Registrant’s Certificate of Incorporation and Bylaws is expressly not exclusive of any other rights to which those seeking indemnification may be entitled as a matter of law.

The Registrant’s Certificate of Incorporation provides that directors of the Registrant will not be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, whether or not an individual continues to be a director at the time such liability is asserted, 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, relating to prohibited dividends or distributions or the repurchase or redemption of stock, or (iv) for any transaction from which the director derives an improper personal benefit.

Section 145(g) of the DGCL and the Registrant’s Certificate of Incorporation and Bylaws grant the Registrant the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Registrant, or is serving as a director, officer, employee or agent of another enterprise at the Registrant’s request, against any liability asserted against, and incurred by, such person in any such capacity or arising out of such person’s status as such, whether or not the Registrant would have the power to indemnify such person against such liability under the provisions of the DGCL. Pursuant to this authority, the Registrant has purchased and maintains directors’ and officers’ liability insurance policies covering certain liabilities that the Registrant’s present and former directors and officers and former directors and officers of acquired subsidiary companies might incur in connection with the performance of their duties.

In addition, the Registrant has entered into indemnification agreements with each of its directors and executive officers which require that the Registrant indemnify those directors and executive officers to the fullest extent permitted by the DGCL and the Registrant’s Certificate of Incorporation and Bylaws, and to advance to them all reasonable expenses incurred in connection with any proceedings, subject to certain defenses.

Item 7. Exemption from Registration Claimed

Not applicable.

Item 8. Exhibits

See the attached Exhibit Index at page 9, which is incorporated herein by reference.

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 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;

(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 Commission 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)    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 (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 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.

(h)    Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, executive officers and controlling persons of the Registrant pursuant to the provisions described in Item 6 above, 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.
