WHEREAS, Seller, Buyer and Broker desire to modify and amend the Original Agreement, in the manner and for the purposes herein set forth.

NOW, THEREFORE, for and in consideration of the covenants contained herein, and other good and valuable consideration, the receipt, adequacy and sufficiency of which are hereby acknowledged by Seller, Buyer and Broker, Seller, Buyer and Broker hereby agree as follows:

1. Extensions of Closing Date. In addition to the extension to the Closing Date set forth in the Original Agreement, Buyer shall have the right to one (1) additional extension of the Closing Date, upon and subject to the following terms and conditions:

3. Physical Improvements; Buyer’s Inspection of Improvements.

(a) Buyer has tested and shall continue to test the SWUD units in the Improvements pursuant to and in accordance with paragraph 5 of the Original Agreement and other terms and provisions thereof. In connection with this testing, Buyer has identified certain repair work that needs to be done on the SWUD units in the Improvements. Subject to subparagraph (c), below, Seller hereby covenants and agrees to reimburse Buyer for the cost of the additional testing necessary to determine any repair work needed or required on the SWUD units, and any necessary or required repair work on the SWUD units themselves, as determined by the testing by, and in the professional judgment of, the party conducting such testing, which repair work shall be satisfactory to Seller, in Seller’s reasonable judgment; such reimbursement to Buyer for the cost of the testing and for the repair work necessary or required to be accomplished shall be effected through a credit against the Purchase Price otherwise due to Seller at Closing.

(b) Seller and Buyer recognize that certain repair work needs to be completed to the heating system in the leased space in the Improvements known as the “Café at Glenlake”. On or before the Closing, Buyer shall provide Seller with an estimate of the cost of such repair work, which estimate shall be satisfactory to Seller, in Seller’s reasonable judgment. Subject to subparagraph (c), below, Buyer shall receive a credit against the Purchase Price otherwise payable by Buyer at Closing for the cost of such repair work, as indicated in the estimate described above.
