ITEM 1.01. Entry into a Material Definitive Agreement

On September 13, 2010, Consolidated Capital Institutional Properties, LP, a Delaware limited partnership (“CCIP”), entered into an agreement and plan of merger (the “Merger Agreement”) with Aimco Properties, L.P., a Delaware limited partnership (“Aimco OP”) and Aimco CCIP Merger Sub LLC, a Delaware limited liability company of which Aimco OP is the sole member (the “Merger Subsidiary”), pursuant to which the Merger Subsidiary will be merged with and into CCIP, with CCIP as the surviving entity.

In the merger, each Series A Unit of CCIP outstanding immediately prior to the consummation of the merger, except those held by limited partners who perfect their appraisal rights pursuant to the Merger Agreement, will be converted into the right to receive, at the election of the limited partner, either (i) $4.31 in cash (the “Cash Consideration”) or (ii) a number of partnership common units of Aimco OP calculated by dividing $4.31 by the average closing price of Apartment Investment and Management Company common stock, as reported on the New York Stock Exchange, over the ten consecutive trading days ending on the second trading day immediately prior to the effective time of the merger (the “OP Unit Consideration”). However, if Aimco OP determines that the law of the state or other jurisdiction in which a limited partner resides would prohibit the issuance of partnership common units of Aimco OP in that state or jurisdiction (or that registration in that state or other jurisdiction would be prohibitively costly), then such limited partner will only be entitled to receive the Cash Consideration for each Series A Unit. Those limited partners who do not make an election will be deemed to have elected to receive cash.

In the merger, Aimco OP’s membership interest in the Aimco Subsidiary will be converted into CCIP Series A Units. As a result, after the merger, Aimco OP will be the sole limited partner in CCIP, holding all outstanding Series A Units. ConCap Equities, Inc. will continue to be the sole general partner of CCIP after the merger, and CCIP’s partnership agreement in effect immediately prior to the merger will remain unchanged after the merger.

Completion of the merger is subject to certain conditions, including approval by a majority in interest of the Series A Units. As of September 10, 2010, CCIP had issued and outstanding 199,030.2 Series A Units, and Aimco OP and its affiliates owned 152,648.05 of those units, or approximately 76.7% of the number of outstanding units. Aimco OP and its affiliates have indicated that they intend to take action by written consent to approve the merger.

The foregoing summary of the Merger Agreement is qualified in its entirety by reference to the Merger Agreement, which is attached hereto as Exhibit 10.1 and incorporated herein by reference.

Additional Information for Investors:

This communication does not constitute an offer to sell or the solicitation of an offer to buy any securities. Aimco OP and Apartment Investment and Management Company will file with the Securities and Exchange Commission a registration statement on Form S-4 that will include an information statement of CCIP relating to the transaction, which will also constitute a prospectus of Aimco OP and Apartment Investment and Management Company. INVESTORS ARE URGED TO READ THE INFORMATION STATEMENT/PROSPECTUS WHEN IT BECOMES AVAILABLE BECAUSE IT WILL CONTAIN IMPORTANT INFORMATION REGARDING THE TRANSACTION.
