LIABILITIES AND INDEMNIFICATION

10.1 The General Partner shall be liable for the debts and obligations of the Partnership. The Limited Partner shall not be liable for the debts and obligations of the Partnership or for any Partnership liabilities or losses beyond the amount of its capital contributions required under Article V of this Agreement.

10.2 The Partnership shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Partnership) by reason of the fact that he is or was a Partner, Management Committee Member, officer, employee or agent of the Partnership (collectively, an “Action”), against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such Action if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Partnership, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any Action by judgment or settlement, conviction or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Partnership, and with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

10.3 Any indemnification under Section 10.2 shall be limited by the provisions of the TRLPA and shall be made by the Partnership only as authorized in the specific case upon a determination that indemnification of the Partner, Management Committee Member, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth therein. Such determination shall be made (a) by the Management Committee by a majority vote of a quorum consisting of Management Committee Members who are not parties to such Action, or (b) if directed by the Management Committee, by independent legal counsel in a written opinion. Notwithstanding the foregoing, to the extent that a Partner, Management Committee Member, officer, employee or agent of the Partnership has been successful on the merits or otherwise in defense of any Action, or in defense of any claim, issue or matter therein, he shall

be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith.

10.4 Expenses (including attorneys’ fees) actually and reasonably incurred by a Partner, Management Committee Member, officer, employee or agent of the Partnership in connection with the defense or disposition of any Action may be paid from time to time by the Partnership in advance of the final disposition thereof upon receipt of (a) an affidavit by such person of his good faith belief that he has met the standard of conduct necessary for indemnification under Section 10.2, and (b) an undertaking by such person to repay to the Partnership the amounts so paid if it is ultimately determined that he is not entitled to indemnification as authorized in Section 10.2, which undertaking may be accepted by the Partnership without reference to the financial ability of such person to make repayment.

10.5 If both the Partnership and any person to be indemnified are parties to an Action, legal counsel representing the Partnership therein may, at the request of such person, also represent such person (unless such dual representation would involve such legal counsel in a conflict of interest in violation of applicable law or principles of professional ethics), and the Partnership shall pay all fees and expenses of such legal counsel incurred during the period of dual representation other than those, if any, that would not have been incurred if legal counsel were representing only the Partnership. Any allocation of fees and expenses between the Partnership and such person made by legal counsel shall be final and binding upon the Partnership and such person.

10.6 The indemnification and advancement of expenses provided in this Article X shall not be deemed exclusive of any other rights to which a Partner, Management Committee Member, officer, employee or agent of the Partnership may be entitled under any contract, agreement or otherwise, both as to action in his official capacity and as to action in another capacity while holding such position or office, and shall continue as to a person who has ceased to be a Partner, Management Committee Member, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such person.

10.7 The Partnership shall have power to purchase and maintain insurance on behalf of any person who is or was a Partner, Management Committee Member, officer, employee or agent of the Partnership, or is or was serving at the request of the Partnership as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the Partnership would have the power to indemnify him against such liability under the provisions of this Article X.
