AGREEMENT

NOW, THEREFORE, in consideration of the mutual covenants set forth herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Sellers and Purchaser hereby agree as follows:

1.Capitalized Terms.  All capitalized terms and phrases used herein but not otherwise defined shall have the same meanings given to them in the Agreement. 

2.Amendment to Seller Financing Provision.  Section 4.6 of the Agreement, regarding the Seller Loans, is hereby deleted in its entirety and replaced with the following:

At Closing, Sellers (or such other AIMCO-affiliated entity as Sellers may select) will offer partial financing to the applicable Purchaser’s Designated Entities for Purchaser’s acquisition of (i) the Runaway Bay I Property, and (ii) the Webb Bridge Crossing Property (collectively, the “Seller Loans”).  The Seller Loans shall be in an amount equal to $3,250,000 with respect to Runaway Bay I and $2,200,000 with respect to Webb Bridge Crossing.  The applicable Seller and Purchaser shall cooperate, using commercially reasonable efforts, to obtain the consent of the applicable Assumption Lender to (a) the recording of a second lien mortgage or deed of trust, as applicable, against the applicable Property as security for that Seller Loan; and (b) authorization for AIMCO or its designated affiliate to assume management responsibilities at the applicable Property in the event of a default by Purchaser (or the applicable Purchaser’s Designated Entity) under the applicable Seller Loan (regardless of whether a default has occurred under the senior Assumed Loan).  In the event the parties are unable to obtain an Assumption Lender’s consent to the imposition of a second lien on the applicable Property, such Seller Loan shall be secured by a pledge of 100% of the ownership interests in such Purchaser’s Designated Entity owning such Property and providing, without limitation, for AIMCO or its designated affiliate to assume management of the applicable entity and of the Property upon a default under such Seller Loan.  Interest shall be payable on the Runaway Bay I Seller Loan at a rate of 0% for the first three (3) years and at a rate of 4% each year thereafter until maturity.  Interest shall be payable on the Webb Bridge Crossing Seller Loan at a rate of 1.4% for the first three (3) years and at a rate of 4% each year thereafter until maturity.  Prior to the Closing Date, Purchaser and Sellers shall agree upon the forms of the loan documents to be executed by the parties with respect to the Seller Loans (including, without limitation, promissory notes, which shall not be subject to offset) (collectively, the “Loan Documents”). 

3.Amendment of Closing Date.  Section 6.2 of the Agreement, regarding the Closing, is hereby deleted in its entirety and replaced with the following: 

“6.2.     Closing Date.  The Closing for each of the Properties except the Copper Mill Property and the Cooper’s Pointe Property shall occur on October 22, 2008 and the Closing for the Copper Mill Property and the Cooper’s Pointe Property shall occur on October 24, 2008 (each, a “Closing Date”), through an escrow with Escrow Agent, whereby the Sellers, Purchaser and their attorneys need not be physically present at the Closing and may deliver documents by overnight air courier or other means.  Notwithstanding the foregoing, with regard to the Copper Mill Property and the Cooper’s Pointe Property, Purchaser may elect, at its option and if unable to Close either such Property on October 24, 2008, to Close such Property on October 29, 2008, by written notice delivered to the applicable Seller on or before 1:00 p.m. PST on October 23, 2008.  In addition, if Purchaser has extended the Closing Date for either the Cooper’s Pointe Property or the Copper Mill Property as provided in the foregoing sentence, Purchaser may elect, at its option and if unable to Close either such Property on October 29, 2008, to Close such Property on October 31, 2008, by written notice delivered to the applicable Seller on or before 1:00 p.m. PST on October 28, 2008.  In the event that on or before October 30, 2008, Purchaser has not obtained Loan Assumption Approval for the Cooper’s Pointe Property, and Purchaser has used its best efforts to obtain such Loan Assumption Approval with respect to such Property, the Closing Date with respect to the Cooper’s Pointe Property shall automatically be extended to November 21, 2008 and the provisions of Section 5.7 of this Agreement shall apply.  If, under Section 5.7 Purchaser is unable to obtain Loan Assumption Approval by November 21, 2008 with respect to the Cooper’s Pointe Property and the applicable Seller has elected to convert Cooper’s Pointe to a Payoff Property, the Closing Date shall be thirty (30) days after the Cooper’s Pointe Seller gives notice of its election to convert the Property to Purchaser.

4.Amendment to Closing Deliveries with Respect to Cooper’s Pointe.  Each reference in Section 6.3(k) and in Section 6.4(h) to “Cooper’s Pointe” is hereby deleted from the Agreement.

5.Amendment to Closing Deliveries with Respect to Hibben Ferry I.  A new Section 6.3(m) is hereby added to the Agreement as follows:

6.3(m)  With respect to the Hibben Ferry I Apartments Property Closing, an assignment of such Seller’s interests under that certain Settlement Agreement Regarding Hibben Ferry II Homeowners Association, Inc. v. Hibben Ferry Recreation, Inc., Hibben Ferry I Apartment Partners, L.P. and AIMCO/Charleston, LLC dated May 13, 2004.

6.Credit to Purchase Price on Springhouse Property.  With respect to the Springhouse Property being sold by Charleston – Oxford Associates Limited Partnership to Springhouse Apartments, LLC (the “Springhouse Purchaser”), at Closing, Springhouse Purchaser shall receive a credit against the Applicable Purchase Price for the Springhouse Property equal to $120,750.00 and Springhouse Purchaser shall assume responsibility for all deficiencies at the Springhouse Property identified by the South Carolina Low Income Housing Authority.

7.Counterparts.  This Third Amendment may be executed in multiple counterparts, each of which shall be an original and all of which together shall constitute one and the same Third Amendment.  It shall not be necessary that each party execute each counterpart, or that any one counterpart be executed by more than one party, so long as each party executes at least one counterpart.

8.Ratification.  Except as expressly set forth in this Third Amendment, all other terms and conditions of the Agreement shall remain unmodified, the same being ratified, confirmed and republished hereby.

9.Governing Law.  This Third Amendment shall be governed by and construed in accordance with the laws of the State of Colorado.
