To the extent that the actual real estate and personal property taxes (on the Tangible Personal Property) and assessments paid differ from the amount apportioned at Closing, the parties shall make all necessary adjustments by appropriate payments between themselves within 30 days of the issuance of final tax bills, subject to the terms of Section 5.3.2.7, with the parties hereto agreeing that all Proration Adjusting Payments (defined in Section 7.4.3.6, below) that required to be made by Seller to Purchaser under this Section 5.3.2.2 shall be paid from the Escrow Fund (as defined in the General Escrow Agreement), and Seller hereby agrees to direct General Escrow Agent to pay such amounts from the Escrow Fund in accordance with Section 7.4.3.6, below.

Collections for the month in which Closing occurs shall be prorated in the same manner as other Rents. Prior to Closing, Seller shall reconcile all Collections and Expenses for the calendar year preceding the year in which the Closing occurs with the tenants. Subsequent to Closing, Purchaser shall calculate adjustments for Expenses incurred and Collections received for the year of Closing, which reconciliation as to electricity usage in Tenant’s premises will be done on a monthly, quarterly or annual basis depending on the terms of the applicable Lease.

If the Indemnifying Party elects to assume such control, the Indemnified Party shall have the right to retain counsel to act on its behalf, but the fees and disbursements of such counsel shall be paid by the Indemnified Party unless the Indemnifying Party consents in writing to the retention of such counsel or unless there exists or is reasonably likely to exist a conflict of interest that would make it inappropriate in the judgment of the Indemnified Party (based upon advice of counsel) for the same counsel to represent both the Indemnified Party and the Indemnifying Party. In the event of such conflict, the Indemnified Party shall be entitled to retain its own counsel in each jurisdiction for which the Indemnified Party determines counsel is required, at the expense of the Indemnifying Party. If the Indemnifying Party, having elected to assume such control, thereafter fails to vigorously defend the Third Party Claim, and such failure continues for ten (10) days after the Indemnifying Party is given written notice of such failure, the Indemnified Party shall be entitled to assume such control; provided, however, that if the Indemnified Party gives a notice of such a failure at any time with respect to any Third Party Claim, it shall not thereafter as a condition to the assumption of control of a Third Party Claim have any obligation to give an Indemnifying Party any other notice of such a failure with respect to such Third Party Claim. In the event that the Indemnifying Party exercises the right to undertake any such defense against any such Third

Party Claim as provided above, the Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is reasonably required by the Indemnifying Party, subject to considerations with respect to the maintenance of privilege. Similarly, in the event the Indemnified Party is, directly or indirectly, conducting the defense against any such Third Party Claim, the Indemnifying Party shall cooperate with the Indemnified Party in such defense and make available to the Indemnified Party, at the Indemnifying Party’s expense, all such witnesses, records, materials and information in the Indemnifying Party’s possession or under the Indemnifying Party’s control relating thereto as is reasonably required by the Indemnified Party, subject to considerations with respect to the maintenance of privilege. No such Third Party Claim may be settled by the Indemnifying Party without the prior written consent of the Indemnified Party unless (i) such settlement involves only the payment of money damages for which the Indemnifying Party is fully liable hereunder, (ii) the settlement does not include or constitute any admission of liability on the part of the Indemnified Party, and (iii) such settlement includes a full release of the Indemnified Party with respect to all liability with respect thereto.

7.4.5 Exclusion of Other Remedies. Other than with respect to fraud, the indemnification provisions and provisions set forth in this Article 7 constitute the sole and exclusive recourse and remedies of the parties for recovery of Claims, Damages, and Expenses arising out of or relating to any matters subject to indemnification under this Article 7.

7.4.6 No Right of Set-Off. Under no circumstances may Purchaser or Seller, as applicable, exercise or assert any right to set off against or reduce any other payment obligation to the other or any Affiliate thereof, with respect to any claim for indemnification hereunder.

7.4.7 Other Limitations. Any liability for indemnification under this Agreement shall be determined without duplication of recovery (i) by reason of the state of facts giving rise to such liability constituting a breach of more than one representation or warranty or (ii) with respect to any liability to the extent that the dollar value thereof is included in the calculation of any Proration Adjustment. Claims, Damages and Expenses shall be reduced by the amount of any insurance proceeds for such Claims, Damages and Expenses actually received by the Indemnified Party with respect to the matters causing such Claims, Damages and Expenses. The Indemnified Parties shall use their respective commercially reasonable efforts to mitigate the amount of any Claims, Damages and Expenses, where practicable and feasible, so long as the applicable Indemnifying Parties reimburse all such Indemnified Parties for all good faith out-of-pocket expenses incurred with respect to such efforts promptly upon written request therefor accompanied by documentation thereof.

12.18 1031 Exchange. Purchaser and Seller understand that either party (the “Exchanging Party”) may designate any individual property in connection with an exchange pursuant to the provisions of Internal Revenue Code Section 1031 (a “Like Kind Exchange”). In the event an Exchanging Party desires to structure the sale as a Like Kind Exchange, the other party (the “Non-Exchanging Party”) shall cooperate with the Exchanging Party and with any lender/accommodator to achieve a successful Like-Kind Exchange; provided, however, that the Non-Exchanging Party shall not have any obligation to incur any costs, expenses or liabilities in connection with any such Like-Kind Exchange (and all such costs shall be borne entirely by the Exchanging Party). The Exchanging Party shall indemnify Non-Exchanging Party from and against all loss, costs and expense incurred by reason of said exchange. This transaction is not contingent upon, and the Closing shall not be delayed as a result of, the success or failure of any such Like-Kind Exchange. The Non-Exchanging Party shall not be required to take title to other property involved in any such exchange or to incur any expenses or liability in connection with any such Like-Kind Exchange. Subject to this Section 12.18, the Non-Exchanging Party agrees to execute any and all commercially reasonable documents and instruments reasonably necessary to effectuate such a Like-Kind Exchange; provided, however, that no such documents shall release or relieve the Exchanging Party of any of its obligations under this Agreement or any of the Transaction Documents. Neither party makes any warranty whatsoever to the other with respect to the qualification of the transaction for tax deferred exchange treatment under Section 1031 of the Code, and neither party shall have any responsibility obligation or liability with respect to the tax consequences to the other.
