At Closing, if Purchaser has received (i) a letter from Lender approving the amounts set forth below, and (ii) evidence that Seller has paid all leasing commissions due to CBRE, then the Purchase Price shall be reduced by an amount equal to the tenant improvement allowance, which is currently anticipated to be $300,000.

This section replaces Section 5 of that certain Third Amendment and Reinstatement of Purchase and Sale Agreement dated November 30, 2012, between Seller and Purchaser (the “Third Amendment”). The Escrow Agreement attached to the Third Amendment is hereby terminated in its entirety. Upon receipt by Purchaser of evidence that (i) all work under the Construction Contract has been completed and paid for (including lien releases) and the applicable lien period has expired, and (ii) all of Lender’s requirements concerning such work have been satisfied and Lender has delivered any excess amounts for such work to Purchaser, Purchaser shall pay to Seller the difference (if any) between the amount of the Purchase Price reduction under this Section 4 and the actual cash paid under the Construction Contract or necessary to finish the work contemplated by the Construction Contract, including but not limited to any inspection of the foundation work required by Lender and payment for any additional security guard required by tenant or any third party. Prior to delivery of any such difference to Seller, Purchaser may retain such amounts that constitute prepaid rent that should have been delivered to Purchaser at Closing in accordance with the terms of the Agreement; provided, however, Purchaser shall not retain any amounts as prepaid rent if (i) within thirty (30) days following Closing Seller delivers estoppels from the affected tenants certifying that there are no prepaid rents under each of the affected tenants’ respective leases; or (ii) such affected tenants do not deliver estoppels to Seller within the time periods allotted under each affected tenant’s lease for the provision of estoppels notwithstanding Seller’s request therefor, in which even such amounts shall be conclusively deemed not to be prepaid rents. At Closing, Seller shall deliver to Purchaser all original lien releases relating to the Construction Contract.

5. Payment to Lindemann Construction. At Closing, Escrow Agent shall deliver to Lindemann Construction $25,986.00 pursuant to that Application and Certificate for Payment dated January 4, 2013 executed in connection with the Construction Contract.

6. Purchase Price Reduction for City Mill Lease. The Purchase Price shall be reduced in an amount equal to $37,272.00, which amount represents the cost of the water valve replacement which occurred in October 2005, and which Landlord was required to pay pursuant to the Lease dated May 24, 2009, Exhibit G #4. According to City Mill’s tenant estoppel, this amount has not been paid to tenant or credited against rent.

7. Holdback. At Closing, Escrow shall withhold $148,000 (the “Holdback”) from the Purchase Price and hold it in Escrow to settle prorations and other costs relating to the Property for a period of 30 days in accordance with the terms of the Agreement; provided, however, that the prorations related to the loan shall be done at Closing in accordance with the terms of the Agreement. Without limiting the foregoing, Seller shall perform and Buyer shall reasonably approve the 2011 and 2012 CAM Reconciliation, which shall be settled and prorated in accordance with the Agreement.

8. Purchase Price. The parties agree that the Purchase Price shall be $29,762,728.00.

9. Default Interest. At Closing, Escrow Agent shall withhold from the Purchase Price and pay to Lender any default interest that Lender may require in connection with the loan that Buyer is assuming. The default interest is anticipated to be $50,000.
