Item 2.       ACQUISITION OR DISPOSITION OF ASSETS

         On June 4, 1998, pursuant to an Agreement and Plan of Merger, dated as
of March 9, 1998 (the "Merger Agreement"), by and between Bay Apartment
Communities, Inc., a Maryland corporation ("Bay"), and Avalon Properties, Inc.,
a Maryland corporation ("Avalon"), Avalon merged with and into Bay (the

Bay changed its name to "Avalon Bay Communities, Inc." ("Avalon Bay").

         Pursuant to the Merger Agreement, holders of Avalon common stock, par
value $.01 per share ("Avalon Common Stock"), are entitled to receive, for each
such share held by them on June 4, 1998 at 10:00 p.m. (Baltimore, Maryland
time) (the "Effective Time"), 0.7683 of a share of Avalon Bay common stock, par
value $.01 per share ("Avalon Bay Common Stock"), and an equal number of
associated rights ("Rights") to purchase, under certain circumstances, one
one-thousandth of a share of the Company's Series E Junior Participating
Cumulative Preferred Stock, par value $.01 per share. In exchange for each share
of Avalon 9.00% Series A Cumulative Redeemable Preferred Stock, par value $.01
per share, holders thereof are entitled to receive, for each such share held by
them at the Effective Time, one share of Avalon Bay 9.00% Series F Cumulative
Redeemable Preferred Stock, par value $.01 per share ("Avalon Bay Series F
Preferred Stock"), and in exchange for each share of Avalon 8.96% Series B
Cumulative Redeemable Preferred Stock, par value $.01 per share, holders thereof
are entitled to receive, for each such share held by them at the Effective
Time, one share of Avalon Bay 8.96% Series G Cumulative Redeemable Preferred
Stock, par value $.01 per share ("Avalon Bay Series G Preferred Stock"). In
addition, any holder of Avalon Common Stock who would otherwise be entitled to
receive a fraction of a share of Avalon Bay Common Stock will instead receive an
amount of cash equal to the product of such fraction and $36.825, subject to
applicable withholding taxes.

         The aggregate liquidation value of the Avalon Bay Series F Preferred
Stock and Avalon Bay Series G Preferred Stock issued in the Merger is
