Except with respect to (i) the representations and warranties of Purchaser set forth herein and (ii) fraud, Adviser, on behalf of each Seller, agrees that none of Purchaser, its Affiliates, or any of its or their respective Representatives shall have any liability to such Seller, its Affiliates, or any of its or their respective Representatives whatsoever due to or in connection with Purchaser’s and its Affiliates’ (including, without limitation, the Partnership) use or non-disclosure of the Information or otherwise as a result of the transactions contemplated hereby, and Adviser, on behalf of each Seller, hereby irrevocably waives any claim that it might have based on the failure of Purchaser and its Affiliates (including, without limitation, the Partnership) to disclose the Information.

of such Seller, would not enter into this Agreement or engage in the transactions contemplated hereby.

Any agreement on the part of any Party to any extension or waiver with respect to this Agreement shall be valid only if set forth in an instrument in writing signed on behalf of such Party. The failure of any Party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

Any purported assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective successors and assigns.

7.9 Specific Enforcement; Jurisdiction.

(a) The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions, or any other appropriate form of equitable relief, to prevent breaches of this Agreement and to enforce specifically the performance of the terms and provisions of this Agreement in any court referred to in Section 7.9(b), without the necessity of proving the inadequacy of money damages as a remedy (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties acknowledges and agrees that the right of specific enforcement is an integral part of the transactions contemplated by this Agreement and without such right, none of the Parties would have entered into this Agreement.

(b) Each of the Parties hereby irrevocably submits to the exclusive jurisdiction of the courts of the State of Delaware for the purpose of any legal action, suit or proceeding arising out of or relating to this Agreement or any of the transactions contemplated hereby, and

The Parties agree that a final trial court judgment in any such legal action, suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law; provided, however, that nothing in the foregoing shall restrict any Party’s rights to seek any post-judgment relief regarding, or any appeal from, such final trial court judgment.

7.10 Waiver of Jury Trial. Each Party hereby waives, to the fullest extent permitted by applicable Law, any right it may have to a trial by jury in respect of any legal action, suit or proceeding arising out of this Agreement or any of the transactions contemplated hereby. Each Party (a) certifies that no representative, agent or attorney of any other Party has represented, expressly or otherwise, that such Party would not, in the event of any legal action, suit or proceeding, seek to enforce the foregoing waiver and (b) acknowledges that it and the other Parties have been induced to enter into this Agreement by, among other things, the mutual waiver and certifications in this Section 7.10.

7.11 Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware, regardless of the Laws that might otherwise govern under applicable principles of conflicts of laws thereof.
