All initially-capitalized terms not otherwise defined herein shall have the meanings set forth in the Purchase Agreement unless the context clearly indicates otherwise.

B. Seller and Buyer have agreed to modify the terms of the Purchase Agreement as set forth in this Second Amendment.

NOW, THEREFORE, in consideration of Buyer’s not terminating the Purchase Agreement pursuant to the terms of Section 5.3 of the Purchase Agreement, and for other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intended to be legally bound, Seller and Buyer agree as follows:

1. Recitals. The Recitals set forth above are hereby incorporated herein by reference as if the same were fully set forth herein.

3. Escrow Agreement Regarding TI Allowance. With respect to any outstanding tenant improvement allowance that may become owed to UNCF under its lease (as the landlord under the lease to UNCF is liable for up to a maximum of $201,953.02, but only as and to the extent that the tenant completes the tenant improvement work in accordance with the terms of the lease; such amounts are the “Remaining UNCF TI Amounts”), Seller and Buyer shall enter into and deliver, and Seller shall direct Brandywine Realty Trust (“BRT”) to enter into and deliver, at the Closing, an agreement among BRT, Seller, Buyer and Escrow Agent, in form and substance reasonably acceptable to each of such parties (the “TI Escrow Document”), receipt of which shall be a condition to Buyer’s obligations to close the Transaction, pursuant to which (a) BRT shall agree to fund $201,953.02 to Seller for Seller to fund into escrow with

Escrow Agent (receipt of such $201,953.02 by Escrow Agent being a condition of Buyer’s obligation to close the Transaction, provided, however, that such amounts are not required to be deposited by Seller or BRT if the TI Escrow Agreement, approved as aforesaid, is not executed and delivered into escrow for Closing pursuant to the Purchase Agreement by Buyer and Escrow Agent) for the payment of any Remaining UNCF TI Amounts; (b) Escrow Agent shall be permitted to advance amounts therefrom to pay Remaining UNCF TI Amounts in accordance with the lease to UNCF (as such lease exists as of the date hereof relative to the Remaining UNCF TI Amounts, Buyer not being permitted to amend any terms relating to the Remaining UNCF TI Amounts without the prior written consent of Seller and BRT, if such amendment would increase or extend the liability of Seller or BRT with respect thereto); and (c) within ten (10) Business Days after passing any deadline under the lease to UNCF for the disbursement by the landlord thereunder for the Remaining UNCF TI Amounts, after which, if UNCF is not entitled to any Remaining UNCF TI Amounts, then such Remaining UNCF TI Amounts shall be disbursed to BRT. Interest on the escrow deposit shall be payable to BRT. BRT joins in this Third Amendment solely to confirm that BRT shall enter into such TI Escrow Document with Buyer at Closing. BRT shall have no rights whatsoever arising from its joining in this Third Amendment, and no liabilities except as set forth above with respect to the TI Escrow Agreement and the $201,953.02 to be deposited thereunder.

4. HVAC Reimbursements. Seller covenants and agrees that, if after the Closing, it receives from tenants at the Property payments from any of such tenants for their HVAC usage at the Property, Seller shall remit such amounts to Buyer within ten (10) business days following Seller’s receipt of the same (a) to the extent that Buyer did not receive a credit at Closing for any of such HVAC costs and (b) to the extent that, pursuant to Section 6.1 of the Purchase Agreement, such Rent or other revenue is attributable to any period on and after the Closing Date and is therefore to be credited and tendered to Buyer under Article 6 of the Purchase Agreement (without duplication of such existing obligation already set forth therein with respect to proration of Rents and other revenues generally).

5. Closing Deadline. Seller and Buyer agree that the Closing Deadline shall be, and hereby is, extended to August 26, 2009, and that, accordingly, by such change in the Closing Deadline, and without limiting any other change resulting from such change in the Closing Deadline, Seller and Buyer acknowledge and agree that the date by which Buyer must notify Seller under Section 8.2(c) of the Purchase Agreement of Buyer’s election to terminate the Purchase Agreement due to Seller’s failure to satisfy the estoppel conditions set forth in Section 8.2(c) on or before three (3) Business Days prior to the Closing Deadline, is now August 21, 2009 (being three (3) Business Days prior to August 26, 2009).
