Section 14.02 Indemnification Procedures. Whenever any claim shall arise for indemnification hereunder, Purchaser shall promptly provide written notice of such claim to the Seller Parties. In connection with any claim giving rise to indemnity hereunder resulting from or arising out of any action by a Person who is not a party to this Agreement, the Seller Parties, at their sole cost and expense and upon written notice to Purchaser, may assume the defense of any such action with counsel reasonably satisfactory to Purchaser. Purchaser shall be entitled to participate in the defense of any such action, with its counsel and at its own cost and expense. If neither of the Seller Parties assume the defense of any such action, Purchaser may, but shall not be obligated to, defend against such action in such manner as it may deem appropriate, including, but not limited to, settling such action, after giving notice of it to the Seller Parties, on such terms as Purchaser may deem appropriate and no action taken by Purchaser in accordance with such defense and settlement shall relieve either of the Seller Parties of their indemnification obligations herein provided with respect to any damages resulting therefrom. Neither of the Seller Parties may settle any action without Purchaser’s prior written consent (which consent shall not be unreasonably withheld or delayed). Section 14.03 Exclusivity. The rights and remedies set forth in this Article XIV shall be exclusive of all other rights to monetary damages that any Party (or any Party’s successors or assigns) would otherwise have at law or in equity in connection with the transactions contemplated by this Agreement or any of the other Transaction Documents, other than with respect to claims based on common law fraud or rights which by law cannot be waived or limited.

Section 14.05 Tax Treatment of Indemnification Payments. All indemnification payments made under this Agreement shall be treated by the Parties as an adjustment to the Purchase Price for tax purposes, unless otherwise required by applicable Law. Section 14.06 Effect of Investigation. Purchaser’s right to indemnification or other remedy based on the representations, warranties, covenants and agreements of Seller contained herein will not be affected by any investigation conducted by Purchaser, or any knowledge acquired by Purchaser at any time, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or agreement. Section 14.07 Payment of Indemnification Claims. The Seller Parties shall satisfy their obligations within thirty (30) days after the Parties reach agreement on the amount of such indemnification amount, or within thirty (30) days after the entry of a final, non-appealable adjudication, in either case by wire transfer of immediately available funds.

(a) If the Property shall be damaged or destroyed to the extent of more than fifty percent (50%) of the full replacement cost of the Core and Shell (as defined in the Lease), and the repair and restoration of any such damage or destruction cannot be completed within 180 days after the date of the occurrence, then either party may elect to terminate this Agreement by delivery of notice to the other party within thirty (30) days after the date of the occurrence, and the Deposit shall be promptly returned to Purchaser. (b) If Seller fails to deliver an Estimate within the 30-day period set forth in Section 15.01(a) above, Purchaser may elect to terminate this Agreement by delivery of notice to Seller within thirty (30) days after the expiration of the 30-day period set forth in Section 15.01(a) above, and the Deposit shall be promptly returned to Purchaser; provided, however, that if Seller provides an Estimate after such 30-day period set forth in Section 15.01(a) above but before Purchaser exercises its right to terminate hereunder, Purchaser shall not have the right to terminate this Agreement.

possible (but in any event within five (5) days after Seller first learns of same), and the Purchase Price shall be reduced proportionately as to the part of the Property taken. If the amount of the Property so taken is such as to impair substantially the usefulness of the Property for the purposes for which the same are hereby intended, then Purchaser shall have the option to terminate this Agreement and, if Purchaser elects to terminate this Agreement in accordance with the foregoing, the Deposit shall promptly be returned to Purchaser, and the Lease shall remain in full force and effect. If Purchaser does not elect to terminate this Agreement as provided in this paragraph, then, subject to Purchaser’s other rights to terminate as set forth in this Agreement, the transactions contemplated by this Agreement shall proceed as contemplated herein, in which event Purchaser shall be entitled to receive all proceeds of any award or payment in lieu thereof and Purchaser shall have the right to participate with Seller in any proceedings and Seller shall not be entitled to settle any such proceeding without the prior written consent of Purchaser.
