ITEM 1.     CHANGES IN CONTROL OF REGISTRANT.

            On October 1, 1998, Apartment Investment and Management Company, a
Maryland corporation ("AIMCO"), completed the merger of Insignia Financial
Group, Inc., a Delaware corporation ("Insignia"), with and into AIMCO, with
AIMCO being the surviving corporation (the "Insignia Merger"). Pursuant to the
Amended and Restated Agreement and Plan of Merger, dated as of May 26, 1998, by
and among AIMCO, AIMCO Properties, L.P., Insignia and Insignia/ESG Holdings,
Inc., each share of Insignia outstanding as of the effective time of the
Insignia Merger was converted into the right to receive 0.262 shares of AIMCO
Class E Cumulative Preferred Stock, par value $.01 per share, of AIMCO (the
"Class E Preferred Stock"). AIMCO will issue approximately 8.9 million shares
of its Class E Preferred Stock to the former Insignia stockholders. As a result
of the Insignia Merger, AIMCO acquired approximately 51% of the outstanding
common shares of beneficial interest, par value $.01 per share ("IPT Shares"),
of Insignia Properties Trust, a Maryland real estate investment trust ("IPT").
Angeles Realty Corporation II, which is the general partner (the "General
Partner") of Angeles Income Properties, Ltd. IV, is a wholly-owned subsidiary
of IPT.

            Also, effective October 1, 1998, IPT and AIMCO entered into an
Agreement and Plan of Merger (the "IPT Merger Agreement"), pursuant to which
IPT is to be merged with and into AIMCO or a subsidiary of AIMCO (the "IPT
Merger"). The IPT Merger Agreement provides that, upon consummation of the IPT
Merger, IPT shareholders will receive $13.25 per share in cash or $13.28 per
share in shares of Class A Common Stock, par value $.01 per share of AIMCO, at
AIMCO's option, as more fully provided therein. The transactions contemplated
by the IPT Merger Agreement are subject to certain conditions. The IPT Merger
requires the approval of the holders of a majority of the outstanding IPT
Shares. AIMCO has indicated that it expects to vote all of the IPT Shares owned
by it in favor of the IPT Merger, and accordingly IPT shareholder approval is
assured.

            Under the IPT Merger Agreement, AIMCO has agreed to vote all IPT
Shares owned by it and its subsidiaries in favor of the IPT Merger, and in
connection therewith AIMCO has granted an irrevocable limited proxy to Andrew
L. Farkas, James A. Aston and Frank M. Garrison to vote the IPT Shares owned by
AIMCO and its subsidiaries in favor of the IPT Merger (the "Irrevocable Limited
Proxy").

            The IPT Merger Agreement also provides that Andrew L. Farkas, James
A. Aston, Warren M. Eckstein, Frank M. Garrison and Bryan L. Herrman will
continue to serve as trustees of IPT (collectively, the "Continuing Trustees")
until the earlier of the closing of the IPT Merger or the termination of the
IPT Merger Agreement. Pursuant to the IPT Merger Agreement and the Bylaws of
IPT, a majority of the Continuing Trustees must approve, among other things,
the following actions: (i) removal of a Continuing Trustee; (ii) termination of
IPT's independent auditors or the financial advisor or legal counsel for the
IPT Merger; (iii) all alternative proposals to acquire IPT or its subsidiaries;
(iv) amendment or waiver of any provision of (A) the IPT Merger Agreement, (B)
the Fourth Amended and Restated Agreement of Limited Partnership of Insignia
Properties, L.P., (C) the Declaration of Trust of IPT or (D) the Bylaws of IPT;
(v) modification of the powers of the Continuing Trustees, and (vi) making of
loans by IPT or its subsidiaries to AIMCO or its subsidiaries. The Continuing
Trustees' special powers terminate on the earliest to occur of (i) the IPT
Merger, (ii) January 1, 2002 or (iii) the sooner termination of the IPT Merger
Agreement under certain circumstances.

            In connection with the execution of the IPT Merger Agreement, AIMCO
and certain shareholders of IPT entered into an agreement, dated October 1,
1998 (the "Shareholder's Agreement"), whereby AIMCO agreed that, following a
termination of the IPT Merger Agreement under certain circumstances, it will
vote its IPT Shares as follows: for the first two annual meetings of IPT
Shareholders following such a termination, in favor of designees of the
Continuing Trustees so that such designees constitute a majority of the
trustees of the IPT Board, and thereafter in favor of designees of the
Continuing Trustees so that such designees constitute one less than a majority
of the trustees of the IPT Board. The Shareholder's Agreement remains in effect
as long as


                                       2






AIMCO and/or its affiliates own at least 10% of the outstanding IPT Shares, but
terminates upon consummation of the IPT Merger.

            The summary description above of each of the IPT Merger Agreement,
Irrevocable Limited Proxy and Shareholder's Agreement is qualified in its
entirety by reference to Exhibits 2.1, 99.1 and 99.2 attached hereto, each of
which is incorporated herein by reference.
