(b) No Member, except as otherwise specifically provided in the Act, shall be obligated to pay any distribution to or for the account of the Company or any creditor of the Company.

5.2 Indemnification.

(a) The Member, the managers, any officers of the Company appointed by the Board of Managers, and their affiliates, and their respective stockholders, members, managers, directors, officers, partners, agents and employees (individually and collectively, an “Indemnitee”) shall be indemnified and held harmless by the Company from and against any and all losses, claims, damages, liabilities, expenses (including legal fees and expenses), judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative (each a “Claim”), in which the Indemnitee may be involved, or threatened to be involved, as a party or otherwise by reason of such Indemnitee’s status as any of the foregoing, which relates to or arises out of the Company, its assets, business or affairs, if in each of the foregoing cases (i) the Indemnitee acted in good faith and in a manner such Indemnitee believed to be in, or not opposed to, the best interests of the Company, and, with respect to any criminal proceeding, had no reasonable cause to believe such Indemnitee’s conduct was unlawful, (ii) the Indemnitee’s conduct did not constitute gross negligence or willful or wanton misconduct, (iii) the Indemnitee did not breach his, her or its duty of loyalty to the Company, and (iv) the Indemnitee did not receive any improper personal benefit with respect to the transaction at issue. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere, or its equivalent, shall not, of itself, create a presumption that the Indemnitee acted in a manner contrary to that specified in (i), (ii), (iii) or (iv) above. Any indemnification pursuant to this Article V shall be made only out of the assets of the Company, and no Member or manager shall have any personal liability on account thereof.

(b) In the event that an amendment to this Agreement reduces or eliminates any Indemnitee’s right to indemnification pursuant to this Article V, such amendment shall not be effective with respect to any Indemnitee’s right to indemnification that accrued prior to the date of such amendment. For purposes of this subsection (b), a right to indemnification shall accrue as of the date of the event underlying the Claim that gives rise to such right to indemnification.

(c) All calculations of Claims and the amount of indemnification to which any Indemnitee is entitled under this Article V shall be made (i) giving effect to the tax consequences of any such Claim and (ii) after deduction of all proceeds of insurance net of retroactive premiums and self-insurance retention recoverable by the Indemnitee with respect to such Claims.

5.3 Expenses. Expenses (including reasonable legal fees and expenses) incurred by an Indemnitee in defending any claim, demand, action, suit or proceeding described in Section 5.2 may, from time to time, be advanced by the Company prior to the final disposition of such claim, demand, action, suit or proceeding, in the discretion of the Board of Managers, upon receipt by the Company of an undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as authorized in this Article V.

5.4 Non-Exclusivity. The indemnification and advancement of expenses set forth in this Article V shall not be exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any statute, the Act, the Certificate, this Agreement, any other agreement, a vote of the Board of Managers, a policy of insurance or otherwise, and shall not limit in any way any right which the Company may have to make additional indemnifications with respect to the same or different persons or classes of persons, as determined by the Board of Managers. The indemnification and advancement of expenses set forth in this Article V shall continue as

to an Indemnitee who has ceased to be a named Indemnitee and shall inure to the benefit of the heirs, executors, administrators, successors and assigns of such a person.

5.5 Insurance. The Company may purchase and maintain insurance on behalf of the Indemnitees against any liability asserted against them and incurred by them in such capacity, or arising out of their status as Indemnitees, whether or not the Company would have the power to indemnify them against such liability under this Article V.

Article VI.
Dissolution and Termination

6.1 Events Causing Dissolution.

(a) The Company shall be dissolved upon the first to occur of the following events:

(i) The sale or other disposition of substantially all of the assets of the Company and the receipt and distribution of all the proceeds therefrom; or

(ii) Except as otherwise agreed upon in this Agreement, any other event causing a dissolution of the Company under the provisions of the Act.

6.2 Notices to Secretary of State. As soon as possible following the occurrence of the events specified in Section 6.1, the Company shall file a Certificate of Cancellation with the Secretary of State of Delaware.

(a) First, to the payment of debts and liabilities of the Company in the order of priority as provided by law (including any loans or advances that may have been made by the Member to the Company) and the expenses of liquidation.

(b) Second, to the establishment of any reserve which the Board of Managers may deem reasonably necessary for any contingent, conditional or unasserted claims or obligations of the Company. Such reserve may be paid over by the Board of Managers to an escrow agent to be held for disbursement in payment of any of the aforementioned liabilities and, at the expiration of such period as shall be deemed advisable by the Board of Managers, for distribution of the balance in the manner provided in this Article VI.

6.4 In-Kind. Notwithstanding the foregoing, in the event the Board of Managers shall determine that an immediate sale of part or all of the property would cause undue loss to the Member, or the Board of Managers determine that it would be in the best interest of the Member to distribute the property to the Member in-kind, then the Board of Managers may either defer liquidation of, and withhold from distribution for a reasonable time, any of the property except that necessary to satisfy the Company’s debts and obligations, or distribute the property to the Member in-kind.
