7.4 Indemnification.

(a) To the fullest extent permitted by law but subject to the limitations expressly provided in this Agreement, all Covered Persons shall be indemnified and held harmless by the Company from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all threatened pending or completed claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, and whether formal or informal and including appeals, in which any Covered Person may be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as a Covered Person and acting (or refraining to act) in such capacity; provided, that the Covered Person shall not be indemnified and held harmless pursuant to this Agreement if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the Covered Person is seeking indemnification pursuant to this Agreement, the Covered Person acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that the Covered Person’s conduct was unlawful. Any indemnification pursuant to this Section 7.4 shall be made only out of the assets of the Company, it being agreed that the Members shall not be personally liable for such indemnification and shall have no obligation to contribute or loan any monies or property to the Company to enable it to effectuate such indemnification.

(c) The indemnification provided by this Section 7.4 shall be in addition to any other rights to which a Covered Person may be entitled under any agreement, pursuant to any written approval of the Managing Member, as a matter of law, in equity or otherwise, both as to actions in the Covered Person’s capacity as a Covered Person and as to actions in any other capacity, and shall continue as to a Covered Person who has ceased to serve in such capacity and shall inure to the benefit of the heirs, successors, assigns and administrators of the Covered Person.

(d) The Company may purchase and maintain insurance, on behalf of the Covered Persons and such other Persons as the Managing Member shall determine, against any liability that may be asserted against, or expense that may be incurred by, such Person in connection with the Company’s activities or such Person’s activities on behalf of the Company, regardless of whether the Company would have the power to indemnify such Person against such liability under the provisions of this Agreement.

-10-

(e) For purposes of this Article VII, the Company shall be deemed to have requested a Covered Person to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Company also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on a Covered Person with respect to an employee benefit plan pursuant to applicable law shall constitute “fines” within the meaning of Section 7.4(a), and action taken or omitted by it with respect to any employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the best interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose that is in the best interests of the Company.

(f) A Covered Person shall not be denied indemnification in whole or in part under this Section 7.4 because the Covered Person had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

(g) The provisions of this Section 7.4 are for the benefit of the Covered Persons and their heirs, successors, assigns, executors and administrators and shall not be deemed to create any rights for the benefit of any other Persons.

(h) No amendment, modification or repeal of this Section 7.4 or any provision hereof shall in any manner terminate, reduce or impair the right of any past, present or future Covered Person to be indemnified by the Company, nor the obligations of the Company to indemnify any such Covered Person under and in accordance with the provisions of this Section 7.4 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

7.5 Priority. Each Covered Person may have certain rights to indemnification or advancement of expenses provided by or on behalf of the Managing Member or its affiliates (collectively, the “ Member Indemnitors”). Notwithstanding anything to the contrary in this Agreement, to the fullest extent permitted by applicable law: (a) the Company shall be the indemnitor of first resort (i.e., the Company’s obligations to each Covered Person are primary and any obligation of the Member Indemnitors to provide indemnification or advancement of expenses for the same losses incurred by each Covered Person are secondary), (b) the Company shall advance the full amount of expenses incurred by each Covered Person and shall be liable for the full amount of losses to the extent legally permitted and as required by this Agreement, without regard to any rights each Covered Person may have against the Member Indemnitors, and (c) the Company and each Member irrevocably waive, relinquish and release the Member Indemnitors from any and all claims against the Member Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. Notwithstanding anything herein to the contrary, to the fullest extent permitted by applicable law, no advancement or payment by the Member Indemnitors for or on behalf of any Covered Person with respect to any claim for which such Covered Person has sought indemnification or advancement of expenses from the Company will affect the foregoing and the Member Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of such Covered Person against the Company. The Member Indemnitors are express intended third party beneficiaries of the terms of this Section 7.5.
