Item 6.

Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law provides generally that a corporation shall have the power to indemnify any person sued or threatened to be sued as a director, officer, employee or agent of the corporation, or of another corporation if that person is serving at the request of the indemnifying corporation, in non-derivative suits for expenses (including attorneys' fees), judgments, fines and amounts paid in settlement if the person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the indemnifying corporation. In the case of criminal actions and proceedings, the person must also have had no reasonable cause to believe his conduct was unlawful. Indemnification of expenses, actually and reasonably incurred in connection with the defense or settlement of the action is authorized in stockholder derivative suits where the person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the indemnifying corporation and so long as he had not been found liable to the indemnifying corporation. Even in this latter instance, the court may determine that in view of all the circumstances the person is entitled to indemnification for the expenses that the court deems proper. A person sued as a director or officer of a corporation who has been successful in defense of the action must be indemnified by the corporation against expenses.

The Registrant's By-laws include the indemnification provisions excerpted below:

4. (a) The Corporation shall 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, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation) by reason of the fact that he 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, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he 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 his conduct was unlawful.

(b) The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact he 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, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to the Corporation unless and only to the extent that the Court of Chancery or 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, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

All directors and certain officers of the Registrant have entered into an indemnity agreement (the “Indemnity Agreements”) with the Registrant. The Indemnity Agreements describe the substantive and procedural rights of the above individuals to seek indemnity from the Registrant in the event any of them is or will be involved as a party or otherwise to a legal proceeding because any of them is or was a director or officer of the Registrant. The Indemnity Agreement generally provides that the Indemnitees will be indemnified to the fullest extent permitted by applicable law. The Indemnity Agreement generally excludes from its indemnification provisions proceedings initiated against the Registrant by the Indemnitee. This description of the Indemnity Agreement is qualified in its entirety by the form of the Indemnity Agreement, which is an exhibit to the Registrant’s 8-k filed on November 23, 2005.

The Registrant maintains directors' and officers' liability insurance for all its directors and officers.

In addition, under the Plan, any member of the Compensation Committee, which is responsible for the administration of the Plan, is indemnified to the fullest extent permitted by law with respect to any action taken, failure to act or determination made, in good faith in connection with the Plan.

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; 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 periodic 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 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 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 payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in 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.
