NOW, THEREFORE, in consideration of the mutual covenants herein contained, the sum of $10.00 and for other good and valuable consideration, the mutual receipt and legal sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

1. Capitalized Terms. Capitalized terms used in this Amendment shall have the meanings given to them in the Contract, except as expressly otherwise defined herein.

2. No Financing Contingency. Section 8.1.5 of the Contract is hereby deleted, provided that the Capmark Approval Letter (as defined below) has not been revoked or materially amended by Capmark Finance, Inc. (“Capmark”) for any reason, other than due to any act or failure to act by Purchaser or any of its members or principals, including without limitation (x) the failure of Purchaser or any of its members or principals to comply with the terms of the Capmark Approval Letter, (y) any misrepresentation made by Purchaser or any of its members or principals to Capmark in connection with obtaining the Capmark Approval Letter or otherwise, or (z) any change in the financial condition of Purchaser or any of its members or principals. Purchaser shall have no further financing contingency or right to terminate the Contract due to Purchaser’s failure to obtain the Loan Assumption and Approval; provided, however, that Purchaser shall not be obligated to close if (a) the Lender fails to consummate the Loan Assumption and Release due to a default by Seller under the Loan Documents or (b) the Capmark Approval letter has been revoked or materially amended by Capmark for any reason, other than due to any act or failure to act by Purchaser or any of its principals (including any of the matters described in the first sentence of this Section 2). Purchaser acknowledges and agrees that it has received loan assumption approval from the Lender and has accepted such approval on the terms set forth therein and that the terms of Section 4.7.2.2 of the Contract have been satisfied. For purposes hereof, the “Capmark Approval Letter” shall mean that certain letter issued by Capmark to Mr. Meyer Orbach, dated November 20, 2009.

3. Closing Credit. At the Closing, Purchaser shall receive a credit against the Purchase Price in the amount of $136,208, in consideration for Purchaser’s acceptance of the Lender’s requirements that in connection with the loan assumption Purchaser shall fund (x) an escrow in the amount of $52,400 for certain roof and asphalt repairs and (y) $6,984 per month for a replacement reserve.

4. Allocation to Personal Property. The Purchase Price (i.e., $27,810,415) shall be allocated as follows: $1,400,000 shall be allocated to the sale and purchase of the Fixtures and Tangible Personal Property, and the balance of the Purchase Price (i.e., $26,410,415) shall be allocated to the sale and purchase of the Land and Improvements. The Bill of Sale and the Deed shall reflect the foregoing allocations of the Purchase Price.

5. Broker’s Commission. The total commission payable to Purchaser’s Broker, as set forth in Section 9.2 of the Contract, is hereby reduced to $250,500. Purchaser’s Broker shall execute this Amendment to confirm its agreement with the terms of this Section 5.

6. Closing Date Adjournment Right. Purchaser shall have the one-time right, by delivering written notice to Seller not later than 5:00 p.m. (EST) on December 17, 2009, to adjourn the Closing Date to December 23, 2009, provided that Purchaser shall, concurrently with the delivery of such adjournment notice, deliver to Escrow Agent an additional deposit of $250,000, which additional deposit shall be added to (and be deemed to be a part of) the Deposit and applied against the cash portion of the Purchase Price payable at Closing.

7. Miscellaneous. This Amendment may be executed in counterparts, each of which shall be deemed an original and all of which, when taken together, shall constitute a single instrument and may be delivered by facsimile transmission, and any such facsimile transmitted Amendment shall have the same force and effect, and be as binding, as if original signatures had been delivered. As modified hereby, all the terms of the Contract are hereby ratified and confirmed and shall continue in full force and effect.
