| **Item 6.** | **Indemnification of Directors and Officers.** |

---

The Company is incorporated under the laws of the State of Delaware. Section 145 of the Delaware General Corporation Law, as amended, provides that, under certain circumstances, a corporation may 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 by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at its request in such capacity in 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 the person in connection with 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 corporation, and, with respect to any criminal action or proceeding, if they had no reasonable cause to believe the person's conduct was unlawful, except that no indemnification shall be made in respect of any claim, issue or matter by or in the right of the corporation to procure a judgment in its favor as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite an 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.

------

The Company's Amended and Restated Certificate of Incorporation limits the liability of the directors of the Company to the fullest extent permitted under Delaware corporate law. Specifically, the Company's directors will not be liable to the Company or its stockholders for monetary damages for any breach of fiduciary duty by a director, except for liability:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• for any breach of the director's duty of loyalty to the Company or its stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• under Section 174 of the Delaware General Corporation Law; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• for any transaction from which a director derived an improper personal benefit.

If the Delaware General Corporation Law is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Company shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended.

The Company's Amended and Restated Certificate of Incorporation provides that the Company will, in certain situations, indemnify to the fullest extent permitted under and in accordance with the laws of the State of Delaware any person made or threatened to be made a party to a proceeding by reason of that person's former or present official capacity with the Company against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such proceeding. Directors of the Company are and certain other persons may be, subject in each case to certain limitations, entitled to payment or reimbursement of reasonable expenses in advance of the final disposition of the proceeding upon providing an undertaking to repay the amount advanced if it is ultimately determined that he or she is not entitled to indemnification for such expenses.

In addition, the Company has entered into employment agreements with certain of its employees, which require it to, among other things and subject to specified exceptions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• indemnify such employee to the full extent authorized or permitted by applicable law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintain customary director and officer liability insurance policies for the benefit of such employee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• advance expenses incurred by such employee in connection with a threatened, pending or complete action relating to such employee's service to the Company.

The Company maintains a directors' and officers' insurance policy that insures the officers and directors of the Company from claims arising out of an alleged wrongful act by such persons in their respective capacities as officers and directors of the Company.

| **Item 9.** | **Undertakings.** |

---

The Company hereby undertakes:

(1)&nbsp;&nbsp;&nbsp;&nbsp;To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) &nbsp;&nbsp;&nbsp;&nbsp;to include any prospectus required by Section 10(a)(3) of the Securities Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) &nbsp;&nbsp;&nbsp;&nbsp;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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;&nbsp;&nbsp;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)(i) and (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 this Registration Statement.

(2)&nbsp;&nbsp;&nbsp;&nbsp;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; and

(3)&nbsp;&nbsp;&nbsp;&nbsp;To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering.

The Company further 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.

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 provisions described under Item 6 above 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.

------
