(1) the JV Transactions shall be additional exceptions to Section 6.05 of the Credit Agreement and the negative covenants (which for this purpose shall not include financial covenants)

currently contained in the Loan Documents and shall not be counted towards or included in any of the existing baskets set forth therein; provided that the amount of cash Investments (including loans and capital contributions) in the Joint Venture permitted under such additional exceptions shall not exceed $45 million outstanding at any time (which, for the avoidance of doubt, shall be net of the repayment of loans or distributions from the Joint Venture);

(3) the Administrative Agent shall have the power and authority to consent to, on behalf of the Lenders, any structural changes to such formation of the Joint Venture as necessary to close the JV Transactions under the terms of this letter agreement, including the execution and delivery of applicable subordination and non-disturbance agreements; and
