ITEM 5.  OTHER EVENTS

    On October 1, 2001, we filed a Current Report on Form 8-K, relating to the
proposed spin-off of Five Star Quality Care, Inc., one of our wholly owned
subsidiaries, and the proposed acquisition of 31 senior living facilities from
Crestline Capital Corporation.

    We are supplementing our disclosure in the October Form 8-K hereby.

    In connection with the spin-off, we now expect to capitalize Five Star with
net equity of $50 million, rather than $40 million as described in the October
Form 8-K, as reflected in the accompanying pro forma financial statements.

    As of November 5, 2001, we and Crestline entered into an amendment to the
stock purchase agreement relating to the Crestline transaction, which is filed
herewith. The provisions of the amendment do not change, in any material
respect, our disclosure of the Crestline transaction in the October Form 8-K.

    As previously disclosed in the October Form 8-K, the registration statement
filed in connection with the Five Star spin-off has not yet become effective.
Five Star's common shares may not be sold nor may offers to buy be accepted
prior to the time the registration statement becomes effective. This Form 8-K
shall not constitute an offer to sell or the solicitation of an offer to buy
Five Star common shares, nor shall there be any sale of Five Star common shares
in any state in which such offer, solicitation or sale would be unlawful prior
to registration or qualification under the securities laws of such state.

    We have not entered into definitive documentation with Five Star regarding
the terms of the spin-off and related transactions, including its leases with
us. The description of these agreements in the October Form 8-K, as supplemented
hereby, includes the material terms which we currently expect and which are
based on our best estimate as of the date of this Form 8-K. The final terms may
be different from those that we now expect. Final terms are subject to
negotiation between us and Five Star, and are subject to approval by our Board
of Trustees and Five Star's Board of Directors. The final terms may be
influenced by factors which include, but are not limited to, changes to the
status of the economy, industry or regulatory changes, or changes in the
performance or expected performance of the facilities we expect to lease to Five
Star. These changes could affect any of the terms of the leases or the
transaction agreement, or all of them, and may include, for example, an increase
or decrease in the initial capital of Five Star on the date of the spin-off or
an increase or decrease in annual minimum rents, percentage rents, initial term
length or renewal options of the leases. While we are planning on consummating
the spin-off in December 2001, we can give no assurances that the spin-off will
be completed or that the final terms of the spin-off will not differ, including
in material respects, from the terms we currently expect, as described in the
October Form 8-K, as supplemented hereby.

    The Crestline transaction remains subject to conditions, including those
disclosed in the October Form 8-K.

          INTRODUCTION TO PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

  PRO FORMA CONSOLIDATED BALANCE SHEET AS OF SEPTEMBER 30, 2001 AND PRO FORMA
     CONSOLIDATED STATEMENTS OF INCOME FOR THE YEAR ENDED DECEMBER 31, 2000
                  AND THE NINE MONTHS ENDED SEPTEMBER 30, 2001

    The following unaudited pro forma consolidated balance sheet gives separate
effect to: (1) our issuance of 14,047,000 common shares of beneficial interest
in October 2001; (2) the proposed spin-off of Five Star, the commencement of the
lease for 56 facilities which we currently own and certain related transactions
described in the notes thereto; and (3) the proposed Crestline transaction and
the commencement of the lease with Five Star for the 31 facilities thereby
acquired and certain related transactions described in the notes thereto, as
though all such transactions had occurred on September 30, 2001.

    The following unaudited pro forma consolidated statements of income give
separate effect to: (1) our foreclosure or acquisition of facilities from former
tenants, our sale of four properties in October 2000, financing transactions
completed after January 1, 2000 and certain other transactions described in the
notes thereto; (2) the proposed spin-off of Five Star, the commencement of the
lease for 56 facilities which we currently own, and related transactions as
described in the notes thereto; and (3) the proposed Crestline transaction and
the commencement of the lease with Five Star for the 31 facilities thereby
acquired and certain related transactions described in the notes hereto, as
though all such transactions occurred on January 1, 2000.

    The pro forma information is based in part upon our historical financial
statements filed on our Form 10-Q for the quarter ended September 30, 2001 and
Form 10-K for the year ended December 31, 2000, and financial statements of CSL
Group, Inc. and Subsidiaries as Partitioned For Sale to SNH/ CSL Properties
Trust, filed herewith, and the financial statements of our acquired businesses
filed on Form 8-K dated January 30, 2001, as amended, and this pro forma
information should be read in conjunction with all of these financial statements
and notes thereto. In the opinion of management, all adjustments necessary to
reflect the effects of the transactions discussed above have been reflected in
the pro forma information.

    We currently have sufficient financial resources to effect the closing of
the Crestline transaction through a combination of assumed debt, seller
financing, cash on hand and our credit facility (see Notes N and CC). We may
undertake one or more financings from time to time and at any time in the
future. Those financings could include common equity, preferred equity, debt or
other forms of capital. It is likely that any financing will reduce the amount
of proceeds under our revolving credit facility that we use to close the
Crestline transaction, if it closes at all. Any common equity financing will
increase our total shares outstanding and will cause our per share results to be
less than the per share results shown on the accompanying pro forma income
statements, whether or not the Crestline transaction or the spin-off is
completed. Any financing other than common shares will also cause our per share
results to be less than the per share results shown on the accompanying pro
forma income statements, whether or not the Crestline transaction or the
spin-off is completed, because if we undertake these financings, we will likely
incur interest or other fixed charges which are higher than the pro forma
interest charges on outstanding amounts under our credit facility. Although it
is not possible to estimate the effect of future possible financings because
their terms are unknown at this time, their impact may be material.

    The following unaudited pro forma financial data is not necessarily
indicative of what our actual financial position or results of operations would
have been as of the date or for the period indicated, nor does it purport to
represent our financial position or results of operations for future periods.

CONDENSED CONSOLIDATED BALANCE SHEET ADJUSTMENTS (DOLLARS IN THOUSANDS)

FINANCING ADJUSTMENTS

    Subsequent to September 30, 2001, we issued 14,047,000 common shares of
beneficial interest. A portion of the net proceeds of this transaction were
applied to reduce the outstanding balance on our revolving credit facility to
zero.

    A. Represents net cash available for the purpose of funding initial cash
       amounts to be contributed to Five Star, completing the Crestline
       transaction or for general business purposes. (See Note B).

    B.  Amount represents pro forma net cash applied as a reduction of our
       revolving credit facility and remaining cash as follows:

SPIN-OFF ADJUSTMENTS

    Although contingent upon a number of factors at this time, we currently
expect to spin-off our subsidiary, Five Star Quality Care, Inc., which will
separate our real estate ownership activities from our operating activities. The
operating assets and liabilities associated with our ownership of 56 senior
housing facilities which we repossessed or acquired from former tenants will be
contributed to Five Star. In addition, certain properties that are currently not
being operated or leased will be transferred to Five Star.

    D. Represents the real estate, net, of properties and personal property to
       be transferred to Five Star as part of the spin-off.

    E.  Represents cash used to fund initial cash amounts expected to be
       contributed to Five Star.

    F.  Represents patient accounts receivable to be transferred to Five Star as
       part of the spin-off generated by the 56 facilities which will be owned
       by us and leased to Five Star subsequent to the spin-off.

    G. Represents primarily prepaid expenses to be transferred to Five Star as
       part of the spin-off related to the 56 facilities which will be owned by
       us and leased to Five Star subsequent to the spin-off.

    H. Represents accounts payable and accrued expenses to be transferred to
       Five Star as part of the spin-off generated by the 56 facilities which
       will be owned by us and leased to Five Star subsequent to the spin-off.

                        SENIOR HOUSING PROPERTIES TRUST

    I.  In connection with the foreclosures of two former bankrupt tenants,
       Senior Housing identified deferred maintenance at the facilities which
       had been allowed to occur by its former tenants. In connection therewith,
       Senior Housing accounted for the estimated liability to correct this
       deferred maintenance, of which $4,272 remains at September 30, 2001. We
       will transfer this liability, along with the cash to satisfy it, to Five
       Star in the spin-off.

    J.  Represents the estimated net equity (assets in excess of liabilities,
       see Notes D, E, F, G, H, and I) of Five Star and distributed to our
       shareholders in the spin-off.

CRESTLINE TRANSACTION ADJUSTMENTS

    Pursuant to an agreement we announced in August 2001, we expect to acquire
31 senior living facilities from Crestline. Concurrent with the Crestline
transaction, we expect to lease these 31 facilities to Five Star. As described
in this Form 8-K, the Crestline transaction is subject to contingencies and may
not close.

    K.  The Crestline transaction will result in the allocation of consideration
       using the purchase method of accounting. In addition to the payments made
       on the closing date of the Crestline transaction of the contract purchase
       price and adjustments thereto, we estimate we will pay closing costs of
       $10 million and we expect to make a cash payment to Five Star. The
       expected cash payment to Five Star of $3,573 on a pro forma basis is
       intended to compensate Five Star for assuming certain liabilities in
       excess of assets used in the operation of the 31 facilities. Amounts
       allocated to tangible fixed assets are as follows:

    L.  Represents cash used to complete the Crestline transaction (see Note B).

    M. Amounts allocated to other assets represent cash deposits in accounts
       restricted for use: (1) servicing future interest payments on assumed
       mortgage debt; (2) making future payments for real estate taxes on
       properties which secure the related mortgage debt; and (3) cash escrow
       accounts for routine capital expenditures at the facilities. The assets
       received in the Crestline transaction are offset by a deposit in escrow
       that will be applied to the purchase price when the Crestline transaction
       is closed:


                                                           
Assets received.............................................   $7,769

    N. To finance the Crestline transaction and cash payment to Five Star, we
       expect to assume certain existing Crestline debts and to contribute
       additional funds from our own sources:


                                                         
Assumed term debt, including capital leases...............  $233,386

    O. Amounts allocated to other liabilities primarily represent accrued
       interest related to the Crestline debt to be assumed.

       As outlined above, a substantial portion of the debt we expect to incur
       as part of the Crestline transaction will be at floating rates. A
       1/8 percentage point increase in interest rates would produce pro forma
       interest expense which is $397 higher per annum.

       expense and general and administrative expense.

                        CSL GROUP, INC. AND SUBSIDIARIES
              AS PARTITIONED FOR SALE TO SNH/CSL PROPERTIES TRUST

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.  On August 9, 2001, Crestline Capital Corporation ("Crestline Capital") and
    CSL Group, Inc. ("CSL Group") entered into a stock purchase agreement (the
    "Stock Purchase Agreement") with Senior Housing Properties Trust ("SNH") and
    SNH/CSL Properties Trust ("SNH/CSL"). Pursuant to the Stock Purchase
    Agreement, SNH/CSL would purchase the stock of CSL Group and certain other
    subsidiaries of Crestline Capital that compose Crestline Capital's senior
    living business (the "Partitioned Business") for $600 million, including the
    assumption of approximately $235 million in existing debt. The transaction
    is expected to close in the first quarter of 2002 and is subject to a
    successful vote by at least two-thirds of Crestline Capital's shareholders,
    arranging additional mortgage debt financing for $150 million to
    $175 million, obtaining certain consents and customary closing conditions.

    These condensed consolidated financial statements include only the assets
    and liabilities, along with the results from operations generated from the
    Partitioned Business, as described in the Stock Purchase Agreement. The
    Partitioned Business is an organizational unit of Crestline Capital and is
    not a distinct legal entity. As of September 7, 2001, the Partitioned
    Business consisted of the ownership of 31 senior living communities, a
    general partnership interest in one senior living community and a second
    mortgage note receivable on a senior living community.

    The accompanying condensed consolidated financial statements of the
    Partitioned Business have been prepared by management without audit. Certain
    information and footnote disclosures normally included in financial
    statements presented in accordance with generally accepted accounting
    principles have been condensed or omitted. Management believes the
    disclosures made are adequate to make the information presented not
    misleading. However, the condensed consolidated financial statements should
    be read in conjunction with the consolidated financial statements and notes
    thereto included in the Partitioned Business's audited financial statements
    for the fiscal year ended December 29, 2000.

    The accompanying unaudited condensed consolidated financial statements
    reflect all adjustments (which include only normal and recurring
    adjustments) necessary to present fairly the financial position of the
    Partitioned Business as of September 7, 2001 and the results of operations
    and cash flows for the thirty-six week period ended September 7, 2001. All
    significant intercompany accounts and transactions have been eliminated.
    Interim results are not necessarily indicative of fiscal year performance
    because of the impact of seasonal and short-term variations.
