PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

The following documents, filed with the Commission by the Company, are incorporated by reference into the Registration Statement:

In addition, all documents filed by the Company with the Commission pursuant to Sections 13(a), 13(c), 14, and 15(d) of the Exchange Act subsequent to the date of this Registration Statement and prior to the filing of a post-effective amendment to this Registration Statement which

indicates that all the securities offered hereby have been sold or which deregisters all securities then remaining unsold shall be deemed to be incorporated by reference in this Registration Statement and to be a part hereof from the date of the filing of such documents with the Commission. Any statement contained in a document incorporated by reference herein shall be deemed to be modified or superseded for purposes hereof to the extent that a statement contained herein (or in any other subsequently filed document which also is incorporated by reference herein) modifies or supersedes such statement. Any statement so modified or superseded shall not be deemed to constitute a part hereof except as so modified or superseded. Nothing in this Registration Statement shall be deemed to incorporate by reference any documents or portions thereof, whether specifically listed above or filed in the future, that are not deemed “filed” with the Commission pursuant to applicable securities laws and regulations unless the Company expressly provides to the contrary that such documents or portions thereof are incorporated by reference herein.

Section 145 of the Delaware General Corporation Law provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation for another corporation, partnership, joint venture, trust or other enterprise in related capacities against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlements actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he or she is or is threatened to be made a party by reason of such position, if such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of 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.

The Company’s amended and restated certificate of incorporation provides that it will indemnify to the fullest extent permitted by Delaware corporate law each person who was or is a party or 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 Company) by reason of the fact that he or she is or was a director or officer of the Company, or is or was serving at the Company’s request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (all such persons being referred to as an “Indemnitee”), against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the Indemnitee in connection with such action, suit or proceeding, if such Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the Company’s best interests, and, with respect to any criminal action or proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful.

The Company’s amended and restated certificate of incorporation also provides that the Company will indemnify any Indemnitee who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding by or in the right of the Company to procure a judgment in the Company’s favor by reason of the fact that the Indemnitee is or was a director or officer of the Company, or is or was serving at the Company’s request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against all expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of such action, suit or proceeding, and any appeal therefrom, if the Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the Company’s best interests, except that no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the Company, unless and only to the extent that the court determines that, despite such adjudication but in view of all of the circumstances, he or she is fairly and reasonably entitled to indemnification for such expenses. Notwithstanding the foregoing, to the extent that any Indemnitee has been successful, on the merits or otherwise, he or she will be indemnified by the Company against all expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith. If the Company does not assume the defense, expenses must be advanced to an Indemnitee under certain circumstances.

In addition, the Company has entered into indemnification agreements with each of its directors and named executive officers and intends to enter into indemnification agreements with any new director and certain executive officers in the future.

The Company maintains a general liability insurance policy which covers certain liabilities of its directors and officers arising out of claims based on acts or omissions in their capacities as directors or officers.

Certain of the Company’s non-employee directors may, through their relationships with their employers, be insured and/or indemnified against certain liabilities in their capacity as members of the Company’s Board of Directors.

An underwriting agreement the Company may enter into in connection with an offering of shares of Common Stock may also provide that the underwriters will indemnify, under certain conditions, the Company’s directors and officers (as well as certain other persons) against certain liabilities arising in connection with such offering.

Not applicable.

The following exhibits are filed as part of this Registration Statement:

1.    The undersigned registrant hereby undertakes:

(a)    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 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% 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 (1)(a)(i) and (1)(a)(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 Company pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

(b)    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.

(c)    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.

2.    The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company’s annual report pursuant to Section 13(a) or 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.

3.    Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company 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 Company of expenses incurred or paid by a director, officer, or controlling person of the Company 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 Company 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.
