Article 5. Indemnification; Insurance

5.1 Right to Indemnity. If any Member or assignee or any trustee, director, officer, partner, member, or director of any Member or assignee serving on behalf of the Company; the board of directors or managers of any Subsidiary or any committee thereof; or any Director or Officer of the Company or any Subsidiary (an “Indemnitee”) was or is a party or is threatened to be made a party in any threatened, pending or completed action, suit, proceeding or investigation involving a cause of action or alleged cause of action for damages or other relief arising from or related to the business or affairs of the Company or any Subsidiary, the Company (but without recourse to the separate assets of the Member or any assignee) shall indemnify the Indemnitee against all losses, costs and expenses, including judgments and amounts paid in settlement and attorneys fees actually and reasonably incurred by the Indemnitee in connection with the action, suit, proceeding or investigation, so long as the Indemnitee has met the standard set forth in Section 4.5, and, with respect to any criminal action, proceeding or investigation, that she, he, or it had reasonable cause to believe his, hers or its conduct was not unlawful. The termination of any action, suit, proceeding or investigation by judgment, order, settlement or conviction upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that an Indemnitee did not act in good faith and in a manner she, he or it reasonably believed to be in the best interests of the Company or such subsidiary and with the care that an ordinarily prudent person in a like position would use under similar circumstances and, with respect to any criminal action, proceeding or investigation, that she, he or it had reasonable cause to believe his, hers or its conduct was not unlawful.

5.2 Member Determination. Unless indemnification is ordered by a court, the determination for purposes of Section 5.1 whether an Indemnitee met the standard set forth in this Agreement shall be made in the specific case by the Member.

5.3 Advancement of Expenses. Expenses, including attorneys fees, incurred by any Indemnitee (other than any employee or agent of the Company who is not an officer of the Company) in defending any action, suit, proceeding or investigation shall be paid by the Company as they are incurred, in advance of the final disposition of the action, suit, proceeding or investigation, upon the terms and conditions as the Member shall determine. Reasonable expenses, including court costs and attorneys fees, of the type referred to above in this Section 5.3 incurred by an employee or agent of the Company who is not also an officer of the Company may be so paid in the discretion of the Member upon such terms and conditions, if any, as the Member deems appropriate.

5.4 Other Rights to Indemnity or Reimbursement. Notwithstanding the foregoing, indemnification under this Article 5 shall be provided only with respect to losses, costs, expenses, judgments and amounts which otherwise are not compensated for by insurance carried for the benefit of the Company or its Subsidiaries. Any indemnification pursuant to this Agreement shall not be deemed exclusive of any other rights to which those

6

seeking indemnification may be entitled under any rule of law (whether common law or statutory), agreement or arrangement, whether as to action in an official capacity or as to action in another capacity while holding such position or while employed by or acting as agent for the Company or its Subsidiaries, and shall continue as to an Indemnitee who has ceased to serve in any capacity on behalf of the Company or its Subsidiaries and shall inure to the benefit of the heirs, successors, executors and administrators of the Indemnitee.

5.5 Indemnification of Employees and Agents. The Company may indemnify any employee or agent of the Company or its Subsidiaries and any employee or Affiliate or any Director serving on behalf of the Company or its Subsidiaries upon such terms and conditions, if any, as the Member considers appropriate.

5.6 Insurance. The Board shall cause the Company to purchase, procure, establish and maintain any insurance required for carrying out the business and purpose of the Company or otherwise for the protection of the Company, the Member or any Indemnitee who is or was serving at the request of the Company.

5.7 Savings Clause. If this Article 5 or any portion of this Article shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify each Indemnitee as to costs, charges and expenses (including attorneys fees), judgments, fines and amounts paid in settlement with respect to any action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, including any action by or in the right of the Company or any Subsidiary, to the full extent permitted by any applicable portion of this Article that shall not have been invalidated and to the fullest extent permitted by applicable law.

Article 6. Dissolution and Final Liquidation

6.1 Dissolution. Notwithstanding the retirement, resignation, expulsion, bankruptcy or dissolution of the Member, or the occurrence of any other event that terminates the continued membership of the Member in the Company, the term of the Company shall continue from the date of its formation in perpetuity, unless earlier dissolved on the earliest to occur of:

(a) An election to dissolve the Company made by written consent of the Member and the Board; or

(b) The entry of a decree of judicial dissolution under the Act.

6.2 Winding Up. On the dissolution of the Company, the Company’s affairs shall be wound up as soon as reasonably practicable. The winding up shall be accomplished by the Member.
