22. Indemnification

a. Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is involved (including, without limitation, as a witness) in any actual or threatened action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he is or was a director or officer of the Company or, while a director or officer of the Company, is or was serving at the request of the Company as a director, officer, employee or agent of another limited liability company or of a corporation, partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (hereinafter an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as such a director, officer, employee or agent, shall be indemnified and held harmless by the Company to the full extent authorized by the General Corporation Law of the State of Delaware as if such director or officer were a director or officer of a corporation formed under the laws of the State of Delaware, as the same exists or may hereafter be amended, or by other applicable law as then in effect, against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts to be paid in settlement) actually and reasonably incurred or suffered by such indemnitee in connection therewith and such indemnification shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators; provided, however, that except as provided in Section 22(b) with respect to proceedings seeking to enforce rights to indemnification or to advancement of expenses, the Company shall be required to indemnify any such indemnitee seeking indemnification in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Member. The Company shall pay the reasonable expenses (including attorneys’ fees) incurred in defending any such proceeding in advance of its final disposition (hereinafter an “advancement of expenses”); provided, however, that, if the General Corporation Law of the State of Delaware requires, an advancement of expenses incurred by an indemnitee in his or her capacity as a director or officer, as if such director or officer were a director or officer of a corporation formed under the laws of the State of Delaware (and not in any other capacity in which service was or is rendered by such indemnitee while a director, officer or employee, including, without limitation, service to an employee benefit plan), shall be made only upon delivery to the Company of an undertaking, by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined that such indemnitee is not entitled to be indemnified under this Section 22(a), or otherwise; and provided further that except as provided in Section 22(b) with respect to proceedings seeking to enforce rights to indemnification or an advancement of expenses, the Company shall be required to advance expenses to any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Member.

b. Right of Indemnitee to Bring Suit. If a claim under Section 22(a) is not paid in full by the Company (following the final disposition of the proceeding) within sixty days after a written claim has been received by the Company, except in the case of a claim for an advancement of expenses, in which case final disposition of the proceeding is not required and the applicable period shall be twenty days, the indemnitee may at any time thereafter bring suit against the Company to recover the unpaid amount of the claim and, to the extent successful in whole or in part, the indemnitee shall be entitled to be paid the expense of prosecuting such suit. The indemnitee shall be presumed to be entitled to indemnification under this Section 22 upon submission of a written claim (and, in an action brought to enforce a claim for an advancement of expenses, where the required undertaking, if any is required, has been tendered to the Company), and thereafter the Company shall have the burden of proof to overcome the presumption that the indemnitee is not so entitled. Neither the failure of the Company (including the Member, independent legal counsel, or its stockholders), to have made a determination prior to the commencement of such suit that indemnification of the indemnitee is proper in the circumstances, nor an actual determination by the Company (including its Member, independent legal counsel or its stockholders) that the indemnitee is not entitled to indemnification, shall be a defense to the suit or create a presumption that the indemnitee is not so entitled.

c. Contract Rights. The rights to indemnification and to advancement of expenses conferred upon an indemnitee pursuant to Section 22(a) and (b) shall be contract rights, and any amendment to or repeal of this Section 22 (or any provision thereof) shall not adversely affect any right to indemnification or advancement of expenses with respect to acts or omissions of such indemnitee occurring prior to such amendment or repeal (regardless of whether the proceeding relating to such acts or omissions is commenced before or after such amendment or repeal).

d. Nonexclusivity of Rights. The rights to indemnification and to the advancement of expenses conferred in this Section 22 shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of this Agreement, any indemnity agreements whether now existing or hereinafter entered into, any action of the Member or otherwise.

e. Insurance, Contracts and Funding. The Company may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Company or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Company, if it were a corporation organized under the General Corporation Law of the State of Delaware, would have the power to indemnify such person against such expense, liability or loss under the General Corporation Law of the State of Delaware. The Company may enter into contracts with any indemnitee in furtherance of the provisions of this Section and may create a trust fund, grant a security interest or use other means (including, without limitation, a letter of credit) to ensure the payment of such amounts as may be necessary to effect indemnification as provided in this Section.

5

f. Wholly Owned Subsidiaries. Any person who is or was serving as a director of any wholly owned subsidiary of the Company shall be deemed, for purposes of this Section 22 only, to be a director, officer or employee of the Company entitled to indemnification under this Article.

g. Indemnification of Employees and Agents of the Company. The Company may, by action of the Member from time to time, in its discretion and upon such terms and conditions, if any, as it deems appropriate under the circumstances, grant rights to indemnification and advancement of expenses to employees and agents of the Company to the full extent authorized by the General Corporation Law of the State of Delaware, as if the Company were a corporation organized under the General Corporation Law of the State of Delaware, or the Act, in each case as the same exists or may hereafter be amended, or by other applicable law as then in effect. The Company may, by action of the Member from time to time, authorize one or more officers to grant rights to indemnification and advancement of expenses to employees and agents of the Company, in the discretion of such officer or officers and upon such terms and conditions, if any, as such officer or officers deem appropriate under the circumstances, in each case to the full extent authorized by the General Corporation Law of the State of Delaware, as if the Company were a corporation organized under the General Corporation Law of the State of Delaware, as the same exists or may hereafter be amended, or by other applicable law as then in effect.

23. Assignments. The Member may transfer, assign, pledge or hypothecate, in whole or in part, its limited liability company interest, as determined in its sole discretion.

24. Termination of Membership. The rights of the Member to share in the profits and losses of the Company, to receive distributions and to assign its interest in the Company pursuant to Section 23 shall, on its dissolution, termination, winding-up, bankruptcy or other inability to act in such capacity, devolve on its legal representative for the purpose of settling its estate or administering its property.

a. The Company shall dissolve, and its affairs shall be wound up upon the first to occur of the following:
