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

2.HVAC Alarm Repair. In Section 12(a)(i) of the Fourth Amendment, Purchaser agreed, as a condition of Closing, to undertake HVAC Corrective Actions to resolve intermittent alarms from the Trane vertical self-contained heating, cooling and air conditioning units located in the Building’s mechanical room so that such units would operate within manufacturers specifications. As of the Closing Date, the HVAC Corrective Actions will not be complete, and the parties desire to proceed with Closing according to the terms of the Purchase Agreement; provided, however, that Purchaser and Seller agree that Seller will deposit $14,000.00 (the “HVAC Alarm Escrow Funds”) into escrow at Closing to be administered by the Title Company in accordance with the terms of an escrow agreement, the form of which shall be reasonably agreed to by Purchaser and Seller on or before Closing.

3.Permitted Exceptions.

(a)    Background. Purchaser and Seller acknowledge that Seller made tenant improvement allowances available to two current tenants in the Building: (i) Hot Yoga pursuant to the Hot Yoga Lease (as those terms are defined in Section 7.1(a) of the Original Purchase Agreement, and (ii) Espaces, Inc., a Tennessee Corporation (“Espaces”), pursuant to that certain Lease Agreement between Seller and Espaces dated September 10, 2011 (the “Espaces Lease”). Seller agreed to provide tenant improvement allowances pursuant to the Hot Yoga Lease (the “Hot Yoga Allowance”) and the Espaces Lease (the “Espaces Allowance”). Portions of the Hot Yoga Allowance and the Espaces Allowance remain unpaid by Seller to Hot Yoga and Espaces, and each tenant’s contractors performing the improvements have not issued final unconditional lien waivers for all of the work to be performed under the respective leases. Seller has agreed to provide Purchaser with credits for the unused amounts of the Hot Yoga Allowance and the Espaces Allowance at Closing (the “Tenant Finish Credits”).

(b)    Permitted Exceptions. Purchaser and Seller hereby agree that the definitions of “Permitted Exceptions” and “Required Cure Items”, as set forth in Section 3.2(a) of the Original Purchase Agreement, are hereby amended such that the Title Policy may have an exception for potential mechanics’ liens arising solely from the tenant improvement work to be performed pursuant to the Hot Yoga Lease and the Espaces Lease, which exception will be limited strictly to the amount of the Tenant Finish Credits (the “Limited Mechanics’ Lien Exception”).

(c)    No Deed Claim. Purchaser acknowledges that, notwithstanding that the Limited Mechanics’ Lien Exception is not listed on the exceptions to Seller’s warranty of title in the Deed, Purchaser waives any warranty claim against Seller under the Deed for the Limited Mechanics’ Lien Exception, to the extent of the Tenant Finish Credits. The foregoing will survive Closing and delivery of the Deed.
