Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

The Registrant is incorporated under the laws of the State of Delaware. Section 145 of the Delaware General Corporation Law (the “DGCL”) provides that a Delaware corporation may indemnify any persons who are, or are threatened to be made, parties 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 such corporation), by reason of the fact that such person was an officer, director, employee or agent of such corporation, or is or was serving at the request of such person as an officer, director, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was illegal.

Our Fourth Amended and Restated Certificate of Incorporation, as amended (the “Charter”), and Amended and Restated Bylaws (the “Bylaws”) provide for the indemnification of our directors and officers to the fullest extent permitted under the Delaware General Corporation Law. The Bylaws further provide that the Registrant shall indemnify any Indemnitee pursuant to the provisions described in the immediately foregoing paragraph who has been successful on the merits or otherwise in the defense of any action, suit or proceeding, any claim, issue or matter therein or on appeal from any such action suit or proceeding. The Registrant will advance expenses incurred by an indemnitee who is a party or is otherwise involved in a proceeding, action, suit, or investigation or appeal therefrom in advance of the final disposition of such proceeding, upon receipt of an undertaking by or on behalf of such Indemnitee to repay such amount if it is ultimately determined by final judicial decision that such person is not entitled to indemnification, that the Indemnitee did not act in good faith and in a manner reasonably believed to be in the best interests or not opposed to the Registrant, or with respect to any criminal action, indemnitee had reasonable cause to believe his or her conduct was unlawful. The Registrant will not indemnify an indemnitee to the extent such indemnitee is reimbursed from proceeds of insurance.

Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duties as a director, except for liability for any:

· transaction from which the director derives an improper personal benefit;

· act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

· unlawful payment of dividends or redemption of shares; or

· breach of a director’s duty of loyalty to the corporation or its stockholders.

Our Charter includes such a provision.

The Registrant has entered into indemnification agreements with each of its directors and executive officers. These agreements, among other things, would require the Registrant to indemnify each director and officer to the fullest extent permitted by the DGCL, the Charter and the Bylaws, for expenses such as, among other things, attorneys’ fees, judgments, fines, and settlement amounts incurred by the director or executive officer in any action or proceeding, including any action by or in the Registrant’s right, arising out of the person’s services as its director or executive officer or as the director or executive officer of any subsidiary of the Registrant or any other company or enterprise to which the person provides services at the Registrant’s request. At present, there is no pending litigation or proceeding involving any of our directors or executive officers as to which indemnification is required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for indemnification. The Registrant also maintains directors’ and officers’ liability insurance.

The Commission has taken the position that personal liability of directors for violation of the federal securities laws cannot be limited and that indemnification by the Registrant for any such violation is unenforceable. The limitation of liability and indemnification provisions in the Charter and Bylaws may discourage stockholders from bringing a lawsuit against the Registrant’s directors and officers for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against the Registrant’s directors and officers, even though an action, if successful, might benefit the Registrant and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that the Registrant pays the costs of settlement and damage awards against directors and officers as required by these indemnification provisions.

The foregoing summaries are necessarily subject to the complete text of the DGCL, the Charter, the Bylaws and the indemnification agreements with each of the Registrant’s directors and executive officers referred to above and are qualified in their entirety by reference thereto.

See also the undertakings set forth in response to Item 9 hereof.

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 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 a 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)(i) and (a)(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 Section 15(d) of the Exchange Act that are incorporated by reference in the 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 herein, 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 this registration statement shall be deemed to be a new registration statement relating to the securities offered herein, 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, 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.
