SECOND AMENDMENT TO REAL ESTATE SALE AGREEMENT

This SECOND AMENDMENT TO REAL ESTATE SALE AGREEMENT (“Amendment”) is made on September 6, 2007 between CMD REALTY INVESTMENT FUND IV, L.P., an Illinois limited partnership (“Seller”), and HARVARD PROPERTY TRUST, LLC, a Delaware limited liability company, dba Behringer Harvard Funds (“Purchaser”).

A.                                   Seller and Purchaser entered into the Real Estate Sale Agreement, dated August 15, 2007, regarding the sale and purchase of the office buildings and related improvements commonly known as “Northpoint Central”, “2603 Augusta” and “Regency Center” located in Houston, Texas and that certain First Amendment to Real Estate Sale Agreement dated September 5, 2007 (collectively, the “Original Sale Agreement”).

B.                                     Seller has requested Purchaser to waive the estoppel conditions and related rights set forth in Section 7 of the Original Sale Agreement.  Purchaser is willing to waive such conditions and rights subject to the terms and conditions set forth in this Amendment.

Seller and Purchaser agree as follows:

1.                                       Defined Terms.  All of the terms used in this Amendment have the same meanings set forth for such terms in the Original Sale Agreement, except to the extent expressly provided otherwise in this Amendment.  The term “Sale Agreement” means the Original Sale Agreement, as amended by this Amendment and as hereafter further amended from time to time.

2.                                       Estoppel Conditions.  Purchaser hereby waives the Tenant Estoppel Condition set forth in Section 7(a) of the Original Sale Agreement and all rights to terminate the Sale Agreement under Section 7(a) and Section 7(d) of the Original Sale Agreement.  Seller and Purchaser each waive the Extension Right under Section 7(c) of the Original Sale Agreement.  Purchaser hereby acknowledges and agrees that it received an estoppel certificate from the Association which satisfies the requirements of Section 7(b) of the Original Sale Agreement.

3.                                       T.R. Moore — Indemnity.  T.R. Moore & Company, P.C. (“T.R. Moore”), a tenant under one of the Leases, has not as of the date hereof, delivered to Seller and Purchaser a tenant estoppel certificate that is acceptable to Purchaser.  T.R. Moore has stated in its estoppel certificate that it believes it may have been overcharged for operating expenses for prior years (the “Base Year Claim”.)  Notwithstanding the Base Year Claim, Purchaser has agreed to waive its Tenant Estoppel Condition and proceed to Closing.  In consideration of the foregoing, Seller hereby agrees to indemnify, defend and hold Purchaser harmless from and against all claims(including reasonable attorneys’ fees)  by T.R. Moore with respect to the Base Year Claim (the “Base Year Indemnity”), provided, however, in no event shall Seller’s liability under the foregoing Base Year Indemnity exceed $50,000.00.  In addition, upon Closing, Seller shall deposit into escrow out of the proceeds of Closing the sum of $50,000.00 (the “Base Year Claim Security”) to provide Purchaser with adequate funds necessary to resolve the Base Year Claim with T.R. Moore and to secure Seller’s performance under the Base Year Indemnity.  The Base Year Claim Security shall be held in escrow following the Closing and disbursed by

Escrow Agent pursuant to the “Post-Closing Escrow Agreement” attached hereto and made a part hereof as Exhibit A.  Seller and Purchaser each hereby covenant and agree to execute and deliver to the other at Closing the Post-Closing Escrow Agreement attached hereto as Exhibit A.  In addition, it shall be a condition precedent to Purchaser’s obligation to close the transaction contemplated under the Sale Agreement that the Base Year Claim Security be deposited in escrow with the Escrow Agent and that Seller execute and deliver to Purchaser (through the closing escrow) the Post-Closing Escrow Agreement.

4.                                       Survival.  Seller’s obligations under the Base Year Indemnity shall survive until the earlier of (1) the date Purchaser and T.R. Moore settle the Base Year Claim, (2) the date the entire Base Year Security has been paid out of the escrow pursuant to the terms of the Post-Closing Escrow Agreement and (3) August 31, 2009 (the Termination Date”).  On the Termination Date, the Base Year Indemnity shall be deemed to be of no further force or effect, and Purchaser shall be deemed to have released Seller from all claims with respect to all matters related to the Base Year Claim.

5.                                       Full Force and Effect.  Except to the extent expressly provided otherwise in this Amendment, all of the terms and conditions set forth in the Original Sale Agreement shall remain in full force and effect.

6.                                       Counterparts; Facsimile; E-Mail.  This Amendment may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.  For purposes of this Amendment, any signature transmitted by facsimile or e-mail (in pdf format) shall be considered to have the same legal and binding effect as any original signature.
