INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

The following documents filed by the Company with the Commission are hereby incorporated by reference in this Registration Statement (other than portions of these documents that are furnished under Item 2.02 or Item 7.01 of a Current Report on Form 8-K, including any exhibits included with such Items):

In addition, all documents subsequently filed by the Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, excluding any information in those documents that is deemed by the rules of the Commission to be furnished but not filed, before the filing of a post-effective amendment that indicates all securities offered herein have been sold or that deregister all securities covered by this registration statement then remaining unsold, shall be deemed to be incorporated by reference in this registration statement and to be a part of this registration statement from the date of filing of such documents.

Any statement contained herein or in any document incorporated or deemed to be incorporated by reference shall be deemed to be modified or superseded for purposes of this registration statement to the extent that a statement contained in any other subsequently filed document which also is or is deemed to be incorporated by reference modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed to constitute a part of this registration statement, except as so modified or superseded.

The opinion of counsel as to the legality of the securities that may be issued under the Plan is given by David C. Sienko, Vice President and General Counsel for the Company. Mr. Sienko is employed by the Company, owns shares of the Company’s Common Stock and is eligible to participate in the Plan.

The Company is organized under the Delaware General Corporation Law (the “DGCL”) which empowers Delaware corporations to indemnify any director or officer, or former director or officer, 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 such person is or was a director or officer 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 in connection with such action, suit or proceeding, provided that such director or officer acted in good faith in a manner reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, provided further that such director or officer has no reasonable cause to believe his conduct was unlawful. The DGCL also empowers Delaware corporations to provide similar indemnity to any director or officer, or former director or officer, for expenses, including attorneys’ fees, actually and reasonably incurred by the person in connection with the defense or settlement of actions or suits by or in the right of the corporation if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the interests of the corporation, except in respect of any claim, issue or matter as to which such director or officer shall have been adjudged to be liable to the corporation unless and only to the extent that the

2

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 of the circumstances of the case, such director or officer is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper. The DGCL further provides that (i) to the extent a present or former director or officer of a corporation has been successful in the defense of any action, suit or proceeding described above or in the defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person, in connection therewith; and (ii) indemnification and advancement of expenses provided for, by, or granted pursuant to, the DGCL shall not be deemed exclusive of any other rights to which the indemnified party may be entitled. The DGCL permits a Delaware corporation to purchase and maintain on behalf of any director or officer, insurance against liabilities incurred in such capacities. The DGCL also permits a corporation to pay expenses incurred by a director or officer in advance of the final disposition of an action, suit or proceeding, upon receipt of an undertaking by the director or officer to repay such amount if it is determined that such person is not entitled to indemnification. The DGCL further permits a corporation, in its original certificate of incorporation or an amendment thereto, to eliminate or limit the personal liability of a director to the corporation or its stockholders for monetary damages for violations of the director’s fiduciary duty except: (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL (providing for liability of directors for unlawful payment of dividends or unlawful stock purchases or redemptions) or (iv) for any transaction from which a director derived an improper personal benefit.

The Company’s Certificate of Incorporation and bylaws provide that the Company shall indemnify its officers and directors to the extent permitted by Delaware law. The Company’s Certificate of Incorporation also eliminates the personal liability of directors to the Company or its shareholders for monetary damages for breach of fiduciary duty to the extent permitted by Delaware law.

In addition, the Company has entered into an Indemnification Agreement with each of its officers and directors, which states that if the officer or director that is a party to the agreement was, is, or becomes a party to or witness or other participant in, or is threatened to be made a party to, or witness or other participant in, any threatened, pending, or completed action, suit, or proceeding or any inquiry or investigation, whether conducted by the Company or any other party, by reason of (or arising in part out of) any event or occurrence related to the fact that the officer or director is or was a director, officer, employee, agent, or fiduciary of the Company or is or was serving at the Company’s request as a director, officer, employee, trustee, agent, or fiduciary of another corporation, partnership, joint venture, employee benefit plan, trust, or other enterprise or by reason of anything done or not done by the officer or director that is a party to the agreement in any such capacity, the Company shall indemnify such officer or director to the fullest extent permitted by law against any and all attorneys’ fees and all other costs, expenses, and obligations paid or incurred in connection with investigating, defending, being a witness in, or participating in any claim described above, and judgments, fines, penalties, and amounts paid in settlement of any claim described above, provided that a member or members of the Company’s board of directors has not concluded upon review of the claim that the director or officer party to the agreement would not be permitted to be indemnified under applicable law. Prior to a change in control of the Company, as defined in the agreement, the director or officer who is a party to the agreement will not be entitled to indemnification in connection with any claim described above by such officer or director against the Company or any other director or officer of the Company except under certain circumstances. In the event of a change in control of the Company, as defined in the agreement, other than a change in control which has been approved by a majority of the Company’s board of directors who were directors immediately prior to such change in control, then with respect to all matters thereafter arising concerning the rights of the director or officer party to the agreement to indemnity payments, the Company is required to seek legal advice only from special, independent counsel selected by such officer or director and approved by the Company.

The foregoing statements are subject to the detailed provisions of the DGCL and the Company’s certificate of incorporation and the Company’s bylaws.

(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 of 1933;

4

(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 Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a twenty percent (20%) 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 periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act of 1934 that are incorporated by reference herein.

(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 Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) 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 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.
