(c) Indemnification. Seller and Buyer jointly and severally agree to indemnify and hold harmless Escrow Agent from and against any and all costs, damages and expenses, including reasonable attorneys’ fees, that said Escrow Agent may incur in its compliance in good faith with the terms of this Agreement; provided, however, this indemnity shall not extend to any act of gross negligence or willful malfeasance on the part of Escrow Agent.

In such event, Buyer may either (a) terminate this Agreement, in which case the Deposit made hereunder (together with all interest accrued thereon) shall be forthwith returned to Buyer, or (ii) if Buyer desires to purchase the Partnership Interests in accordance with the terms of this Agreement, Buyer shall have the right to compel specific performance by Seller hereunder (and recover Buyer’s reasonable attorneys’ fees and costs in connection with Buyer’s specific performance action); provided, that if specific performance is not available to Buyer for any reason, Buyer shall have the right to pursue any and all remedies, at law or in equity, on account of such Seller default.

12.03 Buyer’s Default. If Buyer fails to fulfill any of its obligations under this Agreement, Buyer shall be in default under this Agreement. In such event, Seller may terminate this Agreement. The parties acknowledge that in the event of Buyer’s failure to fulfill its obligations hereunder it is impossible to compute exactly the damages which would accrue to Seller in such event. The parties have taken these facts into account in setting the amount of the Deposit, and hereby agree that (a) such amount (together with the interest earned thereon) is the pre-estimate of such damages which would accrue to Seller, (b) such amount represents damages and not any penalty against Buyer, and (c) if this Agreement shall be terminated by Seller by reason of Buyer’s failure to fulfill Buyer’s obligations hereunder, the Deposit (together with the interest earned thereon) shall be Seller’s full and liquidated damages in lieu of all other rights and remedies which Seller may have against Buyer at law or in equity.

Amount (the “Cap Amount”), and that in no event shall Buyer be entitled to seek or obtain any other damages of any kind, including, without limitation, consequential, indirect or punitive damages.

15.03 Merger. The delivery of the items listed in Section 10.01 hereof by Seller, and the acceptance thereof by Buyer, shall be deemed the full performance and discharge of each and every obligation on the part of Seller to be performed hereunder and shall be merged in the delivery and acceptance of such items, except as provided in Section 15.01 hereof and except for such other obligations of Seller which are expressly provided herein to survive the Closing.
