         This report contains forward-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995, including with
respect to our pending acquisition of 31 senior living properties from
Crestline Capital Corporation and the pending spin-off of our subsidiary,
Five Star Quality Care, Inc. Such forward-looking statements are not
guarantees and involve risks and uncertainties. Actual results may differ
materially from those contained in or implied by the forward-looking
statements as a result of various factors. Such factors include, without
limitation, that we may not complete the Five Star spin-off on contemplated
terms and that we may not acquire the Crestline properties because of
Crestline's or our failure to satisfy conditions to the closing. The
information contained in our Annual Report on Form 10-K, including
information contained in "Business" and "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and our Current Reports on
Form 8-K dated September 21, 2001, October 3, 2001, as amended, and November
5, 2001 also identifies important factors that could cause such differences.

Item 5. Other Items

         On December 13, 2001, we agreed to sell $200 million aggregate
principal amount of our 8 5/8% Senior Notes due 2012 in a public offering. We
expect to issue and deliver these notes on or about December 20, 2001. The
price to the public in the offering was 99.163% of the principal amount. We
intend to use the $194.3 million of expected net proceeds to partially fund
our previously announced planned acquisition of 31 senior living properties
and for general business purposes, including other acquisitions.

         This report does not constitute an offer to sell or the solicitation
of an offer to buy notes, and there shall not be any offer, solicitation of
an offer to buy or sale of the notes in any state or other jurisdiction in
which such offer, solicitation or sale would be unlawful.

         We have previously reported our issuance of 14,047,000 common shares
of beneficial interest, the pending spin-off of our subsidiary, Five Star
Quality Care, Inc., our pending acquisition of 31 properties from Crestline
Capital Corporation, and related pending transactions. Additional pro forma
financial information with respect to these transactions and our sale of
notes is contained in Item 7 of this Report.

         X.   Represents elimination, for any period subsequent to December 31,
              2000, of facilities' operating revenues and expenses, and for any
              period prior to December 31, 2000, of other real estate income.
              These amounts were derived from the operations of facilities that
              were conducted for our own account. The facilities will be
              leased by Five Star subsequent to the spin-off and no longer
              operated for our account.

         Y.   Represents elimination of interest income received from a former
              mortgagee prior to foreclosure.

         Z.   Represents the elimination of historical depreciation expense
              related to the properties to be transferred to Five Star (see
              Note D).

         AA.  Represents minimum rent expected to be paid by Five Star for the
              31 properties which we expect to acquire in the pending
              acquisition. Additional rent equal to 5% of revenues at these
              properties in excess of 2002 revenues is due beginning in 2003.

         BB.  In addition to the minimum rent and additional rent described in
              Note W and Note AA, our lease with Five Star and the Marriott
              management agreements for the 31 properties to be acquired from
              Crestline will require Five Star to deposit a percentage of gross
              revenues from these properties into an FF&E reserve for capital
              expenditures at the 31 properties which we expect to acquire in
              the pending Crestline transaction. The FF&E reserve accounts and
              improvements and other items purchased with those funds will
              belong to us. Accordingly, the periodic deposits will be reported
              as additional rental income to us under GAAP.

         CC.  To complete the purchase from Crestline, we will assume debts as
              described in Note N above. These debts bear interest at various
              rates, including some at floating rates based on LIBOR. The
              applicable interest rates during the pro forma periods, assuming
              LIBOR equals its monthly average during the periods presented,
              were as follows:

                  Some of the debt we will assume in the Crestline transaction
                  requires both interest and principal payments. The weighted

                  As outlined above, a portion of the debt we expect
                  to incur as part of the acquisition of properties
                  from Crestline will be at floating rates. A 1/8
                  percentage point increase in interest rates would
                  produce pro forma interest expense which is $178 higher
                  per annum.
