The Purchase Agreement is hereby further amended by inserting therein the following as Section 12 thereof:

SECTION 12.

EXCHANGE CONTRACT MATTERS.

12.1. Exchanges. The Seller desires to effectuate and the Purchaser agrees to cooperate in effectuating separate tax deferred exchanges of Exchange Properties for the Exchange Parcels on the terms and conditions set forth in this Agreement.

12.2. Exchange Property Credit. In connection with the consummation of any Exchange Closing, the Purchaser shall direct that all or any portion of the Allocable Purchase Price of the applicable Exchange Property equal to the Exchange Value be applied to the acquisition of the applicable Exchange Parcel or held in escrow by the Title Company for such purpose pursuant to Section 12.13 (each such designated amount, an "Exchange Property Credit"). The Purchaser shall be obligated (subject to the terms hereof) to expend cash in an amount not to exceed the Exchange Property Credit to acquire and convey to the Seller pursuant to Exchange Contracts such Exchange Parcels as the Seller may designate. Any Exchange Property Credit shall, from time to time, be reduced by any payments made in connection with the acquisition of the applicable Exchange Parcels. The Title Company shall disburse, at the direction of the Purchaser and the Seller, the unapplied portion of any applicable Exchange Property Credit as may from time to time be required to pay amounts then due under the applicable Exchange Contract. Notwithstanding the foregoing, if the Seller notifies the Purchaser in writing at least 5 days prior to the Closing Date or Exchange Closing Date that it has elected not to designate any Exchange Parcels, the Exchange Value shall be paid to the Seller on such Exchange Closing Date as herein described.

12.3. Designation of Exchange Parcels.

(a). The Seller may from time to time after the date of this Agreement but, in any event, no later than 45 days after the Closing Date, designate one or more parcels of real property as Exchange Parcels, which Exchange Parcels the Purchaser shall acquire and transfer to the Seller, in exchange for the Exchange Properties, upon the terms and subject to the conditions of this Agreement. The Seller shall be unconditionally obligated to accept any Exchange Parcel acquired by the Purchaser pursuant to the terms of this Agreement.

(b). In the event that the Seller does not designate any Exchange Parcels on or before the day within 45 days after the Closing Date, or if the Exchange Property Credit has not been reduced to zero on or before the Final Exchange Closing Date, the provisions of Section 12.11 shall apply.

12.4. Exchange Contracts.

(a). At the request of the Seller and subject to all of the applicable terms and conditions of this Agreement, the Purchaser shall, upon 5 days' prior notice from the Seller, execute and deliver a purchase and sale agreement or an assignment and assumption agreement of the Seller's interest under any purchase and sale agreement, in either case, for the acquisition of one or more Exchange Parcels (any such purchase and sale agreement or assignment thereof, an "Exchange Contract"), it being expressly understood and agreed, however, that the Purchaser's obligation to execute or accept assignment of any Exchange Contract shall be subject to the conditions that:

(i) Pursuant to the terms of such Exchange Contract, the closing thereunder shall be scheduled to occur within 180 days after the Closing Date;

(ii) The aggregate amount of payments required to be made under or in connection with such Exchange Contract, as reasonably estimated by the Purchaser, shall not exceed the unapplied portion of the applicable Exchange Property Credit, unless the Seller shall provide the Purchaser with such assurances regarding the payment of such amounts by the Seller as the Purchaser shall require;

(iii) The Purchaser shall have no rights or obligations under such Exchange Contract, monetary or nonmonetary, including, without limitation, the performance of any due diligence or the giving of any notices, other than the payment of amounts less than or equal to the unapplied portion of the applicable Exchange Property Credit;

(iv) Such Exchange Contract shall permit the Purchaser to designate the Seller as the Purchaser's designee or nominee to receive title to the Exchange Parcel to be conveyed thereunder (the Seller agreeing to accept such title); and

(v) The Purchaser shall be under no duty or obligation to find or assist the Seller in finding or selecting Exchange Parcels suitable for exchange or negotiating its purchase and the Purchaser shall have no responsibility for the failure of the purchase of any Exchange Parcel to be closed or settled by the Exchange Closing Date other than by reason of the Purchaser's willful failure to perform its obligations under this Agreement.

(b). It is further expressly understood and agreed that anything herein to the contrary notwithstanding, the Purchaser shall have no obligation to participate in any exchange contemplated by this Agreement if such exchange would or reasonably could (as determined by the Purchaser's legal counsel) result in:

(i) the recognition of any gain by the Purchaser,

(ii) a tax basis in any Property lower than the tax basis therein that the Purchaser would have had such Property been sold to the Purchaser for an amount equal to the Allocable Purchase Price (subject to adjustment as provided in this Agreement) as contemplated by this Agreement other than the provisions in this Section 12, or

(iii) any other federal or state income tax consequences different from those that would have resulted had such Property been sold to the Purchaser for an amount equal to the Allocable Purchase Price (subject to adjustment as provided in this Agreement) as contemplated by this Agreement other than the provisions in this Section 12.

12.5. Conveyance of Exchange Parcels. At the time of any Exchange Closing, title to the applicable Exchange Parcel shall be conveyed directly to the Seller as the nominee and designee of the Purchaser and the Seller shall accept such title as shall be conveyed thereunder; it being expressly understood and agreed that the Purchaser makes no representations, warranties or covenants with respect to such title, the satisfaction of any conditions precedent under any Exchange Contract or any other matter in regard or pertaining thereto.

12.6. Failure of Exchange Parcels to Close.

Upon assignment of an Exchange Contract to the Seller, the Purchaser shall have no further obligations hereunder with respect to the applicable Exchange Parcels or Exchange Contract.

12.8. Closing Period. Purchaser shall not be obligated to participate in any Exchange Closing prior to the Closing Date or after the date which is 180 days after the Closing Date.

12.9. Reductions to Exchange Property Credit. The applicable Exchange Value and the Purchase Price payable under this Agreement shall be reduced from time to time by (a) the aggregate cash consideration paid by the Purchaser under any Exchange Contract, (b) any costs and expenses incurred by or on behalf of Purchaser in connection with any Exchange Parcel, (c) the amount of any claim or indemnity owing to the Purchaser by or at the direction of the Seller pursuant to this Agreement, (d) the amount of any consideration paid by the Purchaser to the Seller pursuant to this Agreement and (e) the costs and expenses incurred in good faith by or on behalf of the Purchaser in connection with the proposed acquisition of an Exchange Parcel, whether or not an Exchange Contract is executed in connection therewith and whether or not the proposed transaction is consummated.

12.10. Increases to Exchange Property Credit. Regardless of the actual interest earned thereon, there shall be credited to the Exchange Property Credit an amount equal to the interest which would be earned on the amount of such credit outstanding from time to time if it had been deposited with the Title Company earning interest equivalent to the Federal Reserve Bank Discount Rate.

12.11. Final Exchange Closing Date. On a Final Exchange Closing Date, the Title Company shall pay to the Seller an amount equal to the then remaining balance of the Exchange Property Credit, if any, less any payments, if any, then due and unpaid by the Seller to the Purchaser pursuant to this Agreement. Upon such payment, and upon payment of any other sums then due by any party to another party pursuant to this Agreement, such Exchange Contract shall be finally closed and no party shall have any further rights or obligations pursuant thereto, except as otherwise provided herein. Any excess balance in the escrow account then held by Escrow Agent shall be returned to Purchaser.
