          (i) The Company shall, to the maximum extent permitted by law, indemnify and hold harmless each Member, Board representative and Officer and their respective directors, officers, partners, employees, agents and affiliates (each, an “Indemnitee”) from and against any and all liabilities, damages, reasonable expenses (including reasonable legal fees and expenses), judgments, amounts paid in settlement and fines actually and reasonable incurred by such Indemnitee arising out of or in connection with any threatened, pending or completed claim, demand, action, suit or proceeding, whether of a civil, criminal, administrative, investigative or other nature, or any appeal thereof, to which such Indemnitee was or is a party or is threatened to be made a party, by reason of (i)

any such Indemnitee’s status as a Member, Board representative or Officer, or (ii) any action taken or omitted to be taken by any such Indemnitee in any capacity referred to in clause (i) of Section 7(a) (including, without limitation, any such action or omission prior to the formation of the Company or prior to being appointed to such status), relating to this Agreement or the formation, capitalization, business, affairs or management of, or the property of, the Company; provided, however, that the Indemnitee did not act in bad faith and the act or omission which is the basis of such claim, demand, action, suit or proceeding did not involve the fraud, gross negligence or willful misconduct of such Indemnitee; provided, further, that the Company shall indemnify an Indemnitee for the defense of any action brought in the name of the Company to procure a judgment in its favor by a Member only to the extent that such indemnification is permitted by applicable law (including without limitation the Act).

          (iii) The indemnification provided by this Section 7(d) shall be in addition to any other rights to which an Indemnitee may be entitled, and shall continue as to an Indemnitee who has ceased to serve in a capacity for which the Indemnitee is entitled to indemnification.

          (iv) To the extent commercially reasonable, the Company shall have the right to purchase and maintain insurance on behalf of the Indemnitees against any liability which may be asserted against or expense which may be incurred by an Indemnitee in connection with the Company’s activities, whether or not the company would have the power to indemnify an Indemnitee against such liability under the provisions of this Agreement; and the cost of premium of any such insurance shall be borne by the Company.
