(1) Indemnification. The Company shall indemnify, to the full extent that it shall have power under applicable law to do so and in a manner permitted by such law, any person made or threatened to be made a party to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (hereinafter, a “Proceeding”), by reason of the fact that such person is or was a Member, Director or Officer of the Company, or is or was serving at the request of the Company as a Director or Officer of another corporation, partnership, limited liability company, joint venture, trust, or other enterprise. The Company may indemnify, to the full extent that it shall have power under applicable law to do so and in a manner permitted by such law, any person made or threatened to be made party to any Proceeding, by reason of the fact that such person is or was an employee or agent of the Company, or is or was serving at the request of the Company as an employee or agent of another corporation, partnership, limited liability company, joint venture, trust, or other enterprise.

(2) Advancement of Expenses. With respect to any person made or threatened to be made a party to any threatened, pending, or completed Proceeding, by reason of the fact that such person is or was a Member, Director or Officer of the Company, the Company shall pay the expenses (including attorneys’ fees) incurred by such person in defending any such Proceeding in advance of its final disposition (hereinafter an “advancement of expenses”); provided, however, that the payment of expenses (including attorneys’ fees) incurred by such person in advance of the final disposition of such Proceeding shall be made only upon receipt of an undertaking (hereinafter an “undertaking”) by such person to repay all amounts advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (hereinafter a “final adjudication”) that such person is not entitled to be indemnified for such expenses under this Section 10 or otherwise; and further provided that with respect to a Proceeding initiated against the Company by a Member, Director or Officer of the Company (including a person serving at the request of the Company as a director or officer of another corporation, partnership, limited liability company, joint venture, trust, or other enterprise), such Member, Director or Officer shall be entitled under this Section to the payment of expenses (including attorneys’ fees) incurred by such person in defending any counterclaim, cross-claim, affirmative defense, or like claim of the Company in connection with such Proceeding in advance of the final disposition of such proceeding only if such proceeding was authorized by the Board of Directors of the Company. With respect to any person made or threatened to be made a party to any Proceeding, by reason of the fact that such person is or was an employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employee, or agent of another corporation, partnership, limited liability company, joint venture, trust, or other enterprise, the Company may, in its discretion and upon such terms and conditions, if any, as the Company deems appropriate, pay the expenses (including attorneys’ fees) incurred by such person in defending any such Proceeding in advance of its final disposition.

4

(3) Claims. With respect to any person made or threatened to be made a party to any Proceeding, by reason of the fact that such person is or was a Member, Director or Officer of the Company, or is or was serving at the request of the Company as a director or officer of another corporation, partnership, limited liability company, joint venture, trust, or other enterprise, the rights to indemnification and to the advancement of expenses conferred in subsections (1) and (2) above shall be contract rights. If a claim under subsection (1) or (2) above with respect to such rights is not paid in full by the Company within sixty days after a written demand has been received by the Company, except in the case of a claim for an advancement of expenses by an Officer, Director or Member of the Company, in which case the applicable period shall be twenty days, the person seeking to enforce a right to indemnification or an advancement of expenses hereunder may at any time thereafter bring suit against the Company to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Company to recover an advancement of expenses pursuant to the terms of an undertaking, the person seeking to enforce a right to indemnification or an advancement of expenses hereunder or the person from whom the Company seeks to recover an advancement of expenses shall also be entitled to be paid the expenses (including attorneys’ fees) of prosecuting or defending such suit. In any suit brought by a person seeking to enforce a right to indemnification hereunder (but not in a suit brought by a person seeking to enforce a right to an advancement of expenses hereunder) it shall be a defense that the person seeking to enforce a right to indemnification has not met any applicable standard for indemnification under applicable law. In any suit brought by the Company to recover an advancement of expenses pursuant to the terms of an undertaking, the Company shall be entitled to recover such expenses upon a final adjudication that the person from whom the Company seeks to recover an advancement of expenses has not met any applicable standard for indemnification under applicable law. With respect to any suit brought by a person seeking to enforce a right to indemnification hereunder (including any suit seeking to enforce a right to the advancement of expenses hereunder) or any suit brought by the Company to recover an advancement of expenses pursuant to the terms of an undertaking, neither the failure of the Company to have made a determination prior to commencement of such suit that indemnification of such person is proper in the circumstances because such person has met the applicable standards of conduct under applicable law, nor an actual determination by the Company that such person has not met such applicable standards of conduct, shall create a presumption that such person has not met the applicable standards of conduct or, in a case brought by such person seeking to enforce a right to indemnification, be a defense to such suit. In any suit brought by a person seeking to enforce a right to indemnification or to an advancement of expenses hereunder, or by the Company to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the person seeking to enforce a right to indemnification or to an advancement of expenses or the person from whom the Company seeks to recover an advancement of expenses is not entitled to be indemnified, or to such an advancement of expenses, under this Section 10 or otherwise shall be on the Company.

(4) Non-exclusive Rights. The indemnification and advancement of expenses provided in this Section 10 shall not be deemed exclusive of any other rights to which any person indemnified may be entitled under any agreement or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office, and shall

5

continue as to a person who has ceased to be such Member, Director, Officer, employee, or agent and shall inure to the benefit of the heirs, executors, and administrators of such person.

(5) Insurance. The Company may purchase and maintain insurance on behalf of any person who is or was a Member, Director, Officer, employee, or agent of the Company, or is or was serving at the request of the Company as a director, officer, employee, or agent of another corporation, partnership, limited liability company, joint venture, trust, or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the Company would have the power to indemnify such person against such liability under the provisions of this Section 10 or otherwise.
