RECITALS:

A.            Seller and Purchaser entered into a Purchase and Sale Agreement dated as of December 10, 2014, as amended by that certain First Amendment to Purchase and Sale Agreement dated as of December 15, 2014 (collectively, the “Agreement”) to sell and purchase the Property.

B.           Seller and Purchaser wish to further amend the Agreement, as specified below.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto acknowledge and agree as follows:

1.          All capitalized terms used herein and not otherwise defined herein shall have the respective meanings ascribed to them in the Agreement.

2.          Schedule 1.1(a) of the Agreement is hereby deleted in its entirety and replaced with Exhibit A attached hereto.

3.          The following paragraphs are hereby added to the Agreement as Section 11.25:

(a) Purchaser has received the results of radon tests for units number 2 and 8 in Building 4 (the “Initial Units”) which results exceed the United States Environmental Protection Agency recommended action level of 4.0 pCi/l. (the “Action Level”). Purchaser shall have until December 30, 2014 (subject to force majeure and other factors outside of Purchaser's control, such as the loss of test canisters in the mail or invalid test results) to cause the Initial Units to be retested and to receive the results of such retesting. If the new test results for each of the Initial Units are below the Action Level, or in the event Purchaser fails to retest and receive the results of such tests of the Initial Units on or before December 30, 2014, then the patiies shall proceed to Closing in accordance with the terms hereof. If the new test results for either of the Initial Units reveal radon levels at or above the Action Level (a “High Test Result”), to the extent such results have been timely received and communicated to Seller prior to December 30, 2014, then Purchaser shall be entitled to perform radon tests on such other basement or ground floor units, but not any other units, as Purchaser deems necessary (the “Additional Units”); provided, however, that Purchaser shall both conduct such tests and receive the results thereof within ten (10) days of Purchaser's receipt of the test results of the Initial Units, failing which, Purchaser shall be deemed to have waived its right to conduct such additional testing and shall proceed to Closing in accordance with the terms hereof.

(b) If any radon test of any Initial Unit or Additional Unit results in a High Test Result, then the parties shall nonetheless proceed to Closing in accordance with the terms of the Agreement; provided, however, to the extent such radon test of any Initial Unit or Additional Unit has been performed and results received within the timeframes set forth above, Purchaser shall receive a credit at Closing in the amount of Seven Thousand Dollars ($7,000) per Initial Unit or Additional Unit which tested at a High Test Result. In no event shall Purchaser have any right to terminate this Agreement as a result of the testing hereunder.

4.          Purchaser is hereby deemed to have timely delivered the Notice to Proceed pursuant to Section 3.2 of the Agreement and Purchaser shall have no fmiher rights to terminate the Agreement pursuant to Section 3.2.

5.          Intentionally Omitted.

6.          This Amendment shall be governed by and construed in accordance with the laws of the State of Tennessee without reference to the choice of law doctrine of such State.

7.          This Amendment may be executed in any number of identical counterparts, each of which shall be deemed an original, but all of which together shall constitute but one and the same Amendment. Handwritten signatures to this Amendment transmitted by telecopy or electronic transmission (for example, through use of a Portable Document Format or “PDF” file) shall be valid and effective to bind the party so signing. Each party agrees to promptly deliver to the other party an executed original of this Amendment with its actual signature, but a failure to do so shall not affect the enforceability of this Amendment, it being expressly agreed that each party to this Amendment shall be bound by its own telecopied or electronically transmitted handwritten signature and shall accept the telecopied or electronically transmitted handwritten signature of the other party to this Amendment.

8.          In the event of any inconsistency between the terms of this Amendment and the terms of the Agreement, the terms of this Amendment shall prevail.

9.          This Amendment shall be binding upon and inure to the benefit of the parties hereto and to their respective successors and assigns.

10.         Except as expressly amended by this Amendment, the Agreement shall remain in full force and effect. All references to the “Agreement” shall be deemed to be references to the Agreement as amended by this Amendment.
