           $75,000,000 FLOATING RATE SENIOR NOTES, SERIES A, DUE 1999
          $125,000,000 FLOATING RATE SENIOR NOTES, SERIES B, DUE 1999
                            ------------------------
 
     The Floating Rate Senior Notes, Series A, Due 1999 (the "Series A Notes")
and the Floating Rate Senior Notes, Series B, Due 1999 (the "Series B Notes",
and together with the Series A Notes, the "Notes") offered hereby (collectively,
the "Offering") are being issued by Health and Rehabilitation Properties Trust,
a Maryland real estate investment trust ("HRP" or the "Company"), in an
aggregate principal amount equal to $75,000,000 and $125,000,000, respectively.
 
     Interest on the Notes will be payable in U.S. dollars quarterly in arrears
on each January 13, April 13, July 13 and October 13, commencing October 13,
1994, and at maturity or earlier redemption, as the case may be. The interest
rate for each Interest Period (as defined herein) will be subject to quarterly
adjustment effective on the thirteenth day of each January, April, July and
October. The Series A Notes will bear interest at a per annum rate equal to
LIBOR (determined as described herein) plus 1.05% (105 basis points), while the
Series B Notes will bear interest at a per annum rate equal to LIBOR (determined
as described herein) plus .72% (72 basis points). As more fully described
herein, LIBOR will be the rate for deposits in U.S. dollars for a three-month
period that appears on Telerate Page 3750 as of the second London Banking Day
(as defined herein) preceding the first day of the applicable Interest Period,
subject to alternative methods of determining LIBOR described herein. See
"Description of the Notes -- Payments of Principal and Interest on the Notes"
herein.
 
     The Notes will mature on July 13, 1999, but are subject to redemption at
the option of the Company, as a whole or from time to time in part, prior to
maturity on any Interest Payment Date (as defined herein) on and after April 13,
1995, in the case of the Series A Notes, or on and after July 13, 1996, in the
case of the Series B Notes, upon not less than 30 nor more than 60 days' prior
written notice, at a redemption price equal to 100% of the principal amount
thereof, plus accrued and unpaid interest thereon. See "Description of the
Notes -- Maturity and Optional Redemption" herein.
 
     Each series of Notes will be represented by a single fully-registered Note
in book-entry form (each, a "Global Note") registered in the name of the nominee
of The Depository Trust Company ("DTC"). Beneficial interests in a Global Note
will be shown on, and transfers thereof will be effected only through, records
maintained by DTC (with respect to beneficial interests of participants) or by
participants or persons that hold interests through participants (with respect
to beneficial interests of beneficial owners). Owners of beneficial interests in
a Global Note will be entitled to physical delivery of Notes of the same series
in certificated form equal in principal amount to their respective beneficial
interests only under the limited circumstances described under "Description of
the Notes -- Book-Entry System." Settlement for each series of the Notes will be
made in immediately available funds. The Notes will trade in DTC's Same-Day
Funds Settlement System until maturity or earlier redemption, as the case may
be, or until the Notes are issued in certificated form, and secondary market
trading activity in the Notes will therefore settle in immediately available
funds. All payments of principal and interest in respect of the Notes will be
made by the Company in immediately available funds. See "Description of the
Notes -- Same-Day Settlement and Payment."
 
     Application has been made to list each series of Notes for trading on the
New York Stock Exchange.

                         PROSPECTUS SUPPLEMENT SUMMARY
 
     The following summary is qualified in its entirety by the detailed
information appearing elsewhere in this Prospectus Supplement or the
accompanying Prospectus or incorporated herein by reference. Unless otherwise
noted, all information presented herein assumes completion of the transaction
described in "Business -- Recent Developments -- The Marriott Transaction".
 
                                  THE COMPANY
 
     The Company is a real estate investment trust ("REIT") which invests
primarily in retirement communities, assisted living centers, nursing homes and
other long term care facilities. In terms of equity capitalization, the Company
is one of the largest REITs in the United States; the Company has over 57
million common shares of beneficial interest outstanding, book equity of $626
million and an equity market capitalization of over $839 million. After this
Offering, the Company will have total debt of approximately $218 million, or 26%
of the Company's total capitalization. The Company has real estate investments
and commitments in 152 properties, located in 29 states and operated by 36
separate companies. Upon completion of the Marriott Transaction (as defined
herein), approximately 70% of the Company's total investments will be in
properties operated by seven NYSE listed companies.

     [INSERT PIE CHARTS HERE -- see appendix to electronic format document]
 
     The population of the United States is aging. According to information from
the U.S. Census Bureau, the segment of the U.S. population age 65 and over is
increasing and will increase sharply through the year 2020. The Company believes
that the demand for services provided at retirement communities, assisted living
centers and nursing homes should increase as the population ages. Moreover,
during the past ten years the intensity of medical services offered in nursing
homes has become an important factor increasing nursing facility revenues and
the value of facilities. Recently proposed federal healthcare reform legislation
seeks, in part, to control future expenditures for acute care hospitals by
providing increased funding for subacute care in nursing homes. Although the
Company has and will in the future invest in other types of health care real
estate, the Company expects to continue its focus on retirement communities,
assisted living centers and nursing homes.
 
     The Company's principal executive offices are located at 400 Centre Street,
Newton, Massachusetts 02158, and its telephone number is (617) 332-3990.

FINANCING POLICY
 
     The Company utilizes short term and long term borrowings and equity
offerings to finance investments and to pay operating expenses. When variable
rate debt is utilized the Company regularly purchases interest rate futures
contracts to hedge against changes in interest rates. At March 31, 1994, the
Company had outstanding revolving debt totalling $73 million, which was
subsequently repaid from the proceeds of the Equity Offering (as hereinafter
defined). After this Offering and assuming the use of proceeds from this
Offering, the Company's total debt outstanding will be approximately $217.6
million. The supplemental indenture covering the Notes issued in this Offering
includes a covenant prohibiting the Company from maintaining a debt to equity
ratio of greater than 1.5 to 1. However, the Company's borrowing guidelines
established in its bank credit facility and by its Board of Trustees prohibit
the Company from maintaining a debt to equity ratio of greater than 1 to 1,
except in certain limited circumstances. As of March 31, 1994, the Company's
debt to equity ratio was .16 to 1. After this Offering, and assuming the use of
proceeds described herein, the Company's debt to equity ratio on a pro forma
basis will be approximately .35 to 1. The present debt to equity limitations in
the bank credit facility and in Company policy may be changed in the future.
There can be no assurance that equity or debt capital will be available in the
future on reasonable terms to fund the Company's operations or growth.

THE LESSEES AND THE MORTGAGORS
 
     The Company's financial condition depends in part upon the financial
condition of the operators of the Company's Properties. After completion of the
Marriott Transaction, approximately 70% of the Company's total investments will
be in Properties operated by seven NYSE listed companies. Certain information
about publicly owned operators of the Company's Properties contained in their
filings with the Commission or other public sources, or provided by these
companies is set forth in the chart below.

    income for Horizon Healthcare and Hillhaven are for the year ended May 31,
    1993 and may not be indicative of the results which can be expected for the
    year ended May 31, 1994; moreover, annual revenues and net income shown for
    Horizon Healthcare do not reflect the merger of Greenery Rehabilitation
    Group, Inc. ("Greenery") into Horizon Healthcare, consummated in February

     The remaining 30% of HRP's portfolio is operated by a diverse group of 29
privately held companies. Based upon the most current financial reports
available to the Company, the ratio of earnings before depreciation,
amortization, interest, rent and charges subordinated to amounts due the
Company, derived by these 29 operators from the Properties in HRP's portfolio,
is on average, 1.7 to 1.
 
     Additional Security.  In addition to fee ownership of the leased properties
and mortgage liens on the mortgaged properties, certain of the Company's leases
and mortgages contain additional security features. Generally, with respect to
investments originated by the Company, each obligation of an operator to HRP is
subject to cross default provisions with respect to all other obligations of
that operator to HRP, and any collateral pledged by an operator to HRP
constitutes collateral for all obligations of that operator. Certain operators
have pledged additional collateral or provided corporate guarantees, security
deposits, or, in some cases, personal guarantees.

RECENT DEVELOPMENTS
 
     The Marriott Transaction.  On March 17, 1994, the Company agreed to acquire
14 retirement communities for $320 million, subject to adjustment. As of June
29, 1994, the Company had acquired 9 of these properties for $178.1 million.
These 14 communities (the "Marriott Properties") are presently leased to and
operated by a subsidiary of Marriott International Inc. (together with its
subsidiaries, "Marriott") and have been or will be acquired by the Company
subject to the existing leases. The Marriott Properties are located in the
following seven states: Florida -- five; Virginia -- three; Arizona -- two;
California -- one; Illinois -- one; Maryland -- one; and Texas -- one. The
retirement communities offer a continuum of services including independent
living residences, assisted living and on-site skilled nursing facilities. The
Marriott Properties contain a total of 3,952 residences or beds and are triple
net leased to Marriott for initial terms expiring on December 31, 2013, with
renewal options extending for an additional 20 years. The leases provide for
fixed rent aggregating approximately $28 million per year and additional rents
equal to 4.5% of annual revenues from operations in excess of base amounts
determined on a facility by facility basis. All of the leases are subject to
cross default provisions and all of the leases are fully guaranteed by the
parent corporation, a public corporation with a current senior debt rating of
Baa-1 from Moody's Investors Service, Inc. and A- from Standard and Poor's
Corporation. Upon completion of the Marriott Transaction, Marriott will become
the Company's largest single tenant.
 
     The consummation of the Marriott Transaction is subject to conditions and
contingencies customary in transactions of this type, including health care and
other regulatory approvals, and although no assurance can be given that the
remainder of the Marriott Transaction will be consummated, the Company expects
that the acquisition of the remaining 5 properties will close in July 1994. The
Company intends to fund the Marriott Transaction with the net proceeds of this
Offering, available cash, funds available to be drawn under credit facilities,
and the assumption of $17.6 million of industrial revenue bonds. See "Business
- -- Recent Developments -- New Revolving Credit Facility".
 
     New Revolving Credit Facility.  In February 1994, the Company closed a $110
million revolving credit facility from a syndicate of banks (the "New Credit
Facility"). The New Credit Facility replaced the Company's $40 million revolving
credit facility which was scheduled to mature in January 1995. The New Credit
Facility will mature in 1997, unless extended by the parties. Borrowings under
the New Credit Facility bear interest, at the Company's option, at prime or a
spread over LIBOR. On June 15, 1994, the New Credit Facility was revised to
increase the amount available thereunder, lower the interest rate charged on
borrowings and make the facility unsecured.
 
     Equity Offering.  In May 1994, the Company consummated an offering (the
"Equity Offering") of 12,650,000 common shares of beneficial interest from which
the Company received net proceeds of $174.5 million. The proceeds of the Equity
Offering were utilized, in part, to fund the Marriott Transaction and, in part,
to reduce amounts then outstanding under the New Credit Facility.
 
     Change of Name.  On May 17, 1994, the shareholders of the Company approved
an amendment to the Company's Declaration of Trust which will change the
Company's name to "Health and Retirement Properties Trust." The Company expects
that the amendment will become effective on or about July 1, 1994. The Company's
common shares of beneficial interest will continue to be traded on the New York
Stock Exchange under the symbol "HRP."
 
     Other Pending Transactions.  In the ordinary course of its business, the
Company regularly evaluates investment opportunities and enters into contracts
to purchase and lease or mortgage finance health care related real estate.
Several such possible investments are currently under consideration and at
various stages of the contractual process. Similarly, since January 1, 1994, the
Company has received principal prepayments of outstanding mortgages totalling
approximately $16.7 million, and the Company is now engaged in proceedings
relating to the appraisal for a sale of two properties subject to leases
scheduled to expire during 1994. The Company does not believe that consummation
of any one or all of these various pending transactions would have a material
impact upon its financial condition or operations.

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the Notes offered hereby
is estimated to be approximately $196.9 million. If the Notes are sold prior to
the consummation of the balance of the Marriott Transaction, the net proceeds
from the sale of the Notes will be used to fund the Marriott Transaction. If any
portion of the balance of the Marriott Transaction is consummated prior to the
sale of the Notes and the Company utilizes other borrowings to fund such
acquisition, all or a portion of the net proceeds from the sale of the Notes
will be used to repay amounts outstanding under such borrowings, and/or to
reduce amounts outstanding under the Company's credit facilities. In the event
that the balance of the Marriott Transaction is not consummated by the Company,
net proceeds from the sale of the Notes will be used to reduce amounts
outstanding under the Company's revolving credit facility or for working capital
or other general corporate purposes. Pending utilization as set forth above, the
proceeds from the sale of the Notes will be invested in short term investments,
including repurchase agreements.

(1) Includes, as an extraordinary item, the write-off of $4.3 million in
    deferred finance charges (approximately $.13 per Share) resulting from
    prepayment of debt.
(2) Amounts shown represent dividends declared with respect to the periods
    shown. The Company regularly determines and pays dividends based upon Funds
    from Operations (see note 3 below). Because dividends were paid on new
    shares issued prior to the record date for regular quarterly dividends,
    dividends exceeded Funds from Operations during the first quarter of 1994
    and on similar occasions in the past.
(3) Industry analysts generally consider Funds from Operations to be an
    appropriate measure of the performance of an equity REIT. Funds from
    Operations does not represent cash generated from operating activities in
    accordance with generally accepted accounting principles and should not be
    considered as an alternative to net income as an indication of the Company's
    performance or to cash flow as a measure of liquidity. Funds from Operations
    means net income (computed in accordance with generally accepted accounting
    principles), excluding gains (or losses) from debt restructuring and sales
    of property, plus depreciation and amortization, and after adjustments for
    unconsolidated partnerships and joint ventures. Adjustments for
    unconsolidated partnerships and joint ventures will be calculated to reflect
    funds from operations on the same basis. The Company has no partnership or
    joint venture interests.
(4) EBIT means net income (computed in accordance with generally accepted
    accounting principles), excluding gains (or losses) from debt restructuring
    and sales of property, plus interest expense, taxes and amortization of
    deferred finance costs included in depreciation and amortization.
(5) EBITDA means net income (computed in accordance with generally accepted
    accounting principles), excluding gains (or losses) from debt restructuring
    and sales of property, plus depreciation, amortization, interest expense and
    taxes.

                      RATIO OF EBITDA TO INTEREST EXPENSE
 
     Management believes that, as the Company is a REIT which is engaged
principally in the business of net leasing properties on long term bases, the
best measure of funds available for debt service is the ratio of EBITDA to
interest expense. The following table summarizes the Company's ratio of EBITDA
to interest expense on a historic basis and as adjusted for the Marriott
Transaction, the Equity Offering and this Offering.

                            DESCRIPTION OF THE NOTES
 
GENERAL
 
     The Series A Notes and the Series B Notes each constitute a separate series
of Debt Securities (which are more fully described in the accompanying
Prospectus) to be issued pursuant to an Indenture, dated as of June 1, 1994 (the
"Indenture") and a supplemental indenture (the "Supplemental Indenture") dated
as of June 29, 1994, between the Company and Shawmut Bank, N.A., as trustee (the
"Trustee"). The Series A Notes will be limited to $75,000,000 in aggregate
principal amount, while the Series B Notes will be limited to $125,000,000 in
aggregate principal amount. The terms of the Notes include those provisions
contained in the Indenture, the Supplemental Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939, as amended (the
"TIA"). The Notes are subject to all such terms, and holders of Notes are
referred to the Indenture, the Supplement Indenture and the TIA for a statement
thereof. The following summary of certain provisions of the Indenture and the
Supplemental Indenture does not purport to be complete and is subject to and
qualified in its entirety by reference to the Indenture and the Supplemental
Indenture, including the definitions therein of certain terms used below. Copies
of the Indenture, the Supplemental Indenture and the Notes are available for
inspection at the office of the Trustee located at One Federal Street, Boston,
Massachusetts 02211.
 
     The Notes will be direct, unsecured and unsubordinated obligations of the
Company and will rank equally with all other unsecured and unsubordinated
indebtedness of the Company from time to time outstanding. However, the Notes
will be effectively subordinated to mortgages and other secured indebtedness of
the Company. Upon consummation of this Offering and the Marriott Transaction,
the only secured indebtedness of the Company will be approximately $17.6 million
assumed by the Company in the Marriott Transaction in connection with certain
industrial revenue bonds. Adjusting on a pro forma basis for this Offering and
the consummation of the Marriott Transaction, the total outstanding indebtedness
of the Company as of June 29, 1994 was approximately $217.6 million. Subject to
certain limitations set forth in the Supplemental Indenture described below
under the caption "Description of the Notes -- Additional Covenants of the
Company", the Indenture and the Supplemental Indenture will permit the Company
to incur additional indebtedness and additional secured indebtedness.
 
     Each series of Notes will be issued only in fully registered, book-entry
form, in denominations of $1,000 and integral multiples thereof, except under
the limited circumstances described below under "Description of the
Notes -- Book-Entry System."
 
     Except as described under "Certain Covenants -- Existence", "Merger,
Consolidation or Sale" and "Events of Default; Notice and Waiver" in the
accompanying Prospectus and under "Description of the Notes -- Additional
Covenants of the Company" below, the Indenture and the Supplemental Indenture do
not contain any other provisions that would afford Holders of the Notes
protection in the event of (i) a highly leveraged or similar transaction
involving the Company, the management of the Company, or any Affiliate of either
such party, (ii) a change of control, or (iii) a reorganization, restructuring,
merger or similar transaction involving the Company that may adversely affect
the Holders of the Notes. In addition, subject to the limitations set forth
under "Description of Debt Securities -- Merger, Consolidation or Sale" in the
accompanying Prospectus, the Company may, in the future, enter into certain
transactions such as the sale of all or substantially all of its assets or the
merger or consolidation of the Company that would increase the amount of the
Company's indebtedness or substantially reduce or eliminate the Company's
assets, and which may have an adverse effect on the Company's ability to service
its indebtedness, including the Notes.
 
                                      S-14
<PAGE>   15
 
     The Company has no present intention of engaging in a highly leveraged or
similar transaction involving the Company. In addition, certain restrictions on
ownership and transfers of the Company's Shares designed to preserve its status
as a REIT may act to prevent or hinder any such transaction or a change of
control.
 
PAYMENT OF PRINCIPAL AND INTEREST ON THE NOTES
 
     Interest on the Notes will be payable in U.S. dollars quarterly in arrears
on January 13, April 13, July 13 and October 13 of each year (each, an "Interest
Payment Date"), commencing October 13, 1994, and on the date of maturity or
earlier redemption, as the case may be (such date of maturity or earlier
redemption, as the case may be, is herein referred to as the "Maturity Date"
with respect to the principal repayable on such date). The interest so payable
will be paid to the person (the "Holder") in whose name the applicable Note is
registered at the close of business on the date (whether or not a Business Day,
as defined below) fifteen calendar days preceding the applicable Interest
Payment Date or the Maturity Date (each, a "Regular Record Date"). The principal
of each Note payable on the Maturity Date will be paid against presentation and
surrender thereof at the corporate trust office of the Trustee, located
initially at 777 Main Street, Hartford, Connecticut 06115, in such coin or
currency of the United States of America as at the time of payment is legal
tender for the payment of public or private debts.
 
     Interest payable on an Interest Payment Date or the Maturity Date, as the
case may be, will be the amount of interest accrued during the applicable
Interest Period (as defined below). Accrued interest in respect of a Note will
be calculated by multiplying the principal amount thereof by an accrued interest
factor. Such accrued interest factor is computed by adding the interest factor
calculated for each day in the applicable Interest Period. The interest factor
for each day will be computed by dividing the interest rate applicable to such
day by 360.
 
     An "Interest Period" with respect to the Notes is each successive period
from and including the preceding Interest Payment Date (or July 13, 1994 in the
case of the initial Interest Period) to but excluding the applicable Interest
Payment Date or the Maturity Date, as the case may be. If an Interest Payment
Date other than the Maturity Date would otherwise be a day that is not a
Business Day, such Interest Payment Date will be postponed to the succeeding
Business Day, unless such succeeding Business Day is in the succeeding calendar
month, in which case such Interest Payment Date will be advanced to the
preceding Business Day. If the Maturity Date falls on a day that is not a
Business Day, the required payment will be made on the succeeding Business Day
as if it were made on the date such payment was due, and no interest shall
accrue on the amount so payable for the period from and after the Maturity Date.
A "Business Day" is any day, other than a Saturday or Sunday, (i) on which banks
in The City of New York are not required or authorized by law or executive order
to close and (ii) which is also a London Banking Day. A "London Banking Day" is
any day on which dealings in United States dollars are transacted in the London
interbank market.
 
     Interest on the Notes will be payable at a floating rate that will be
subject to quarterly adjustment effective as of the thirteenth day of January,
April, July and October (each, a "Reset Date"); provided, however, that if a
Reset Date would otherwise be a day that is not a Business Day, such Reset Date
will be postponed to the succeeding Business Day, unless such succeeding
Business Day is in the succeeding calendar month, in which case such Reset Date
will be advanced to the preceding Business Day. The "Determination Date"
pertaining to a Reset Date will be the second London Banking Day preceding such
Reset Date.
 
     The interest rate on the Series A Notes in respect of an Interest Period
will be a per annum rate equal to LIBOR (determined by the Calculation Agent (as
defined below) as of the applicable Determination Date), plus 1.05% (105 basis
points), while the interest rate on the Series B Notes in respect of an Interest
Period will be a per annum rate equal to LIBOR (determined by the Calculation
Agent as of the applicable Determination Date), plus .72% (72 basis points);
provided, however, that the interest rate on the Notes in respect of an Interest
Period may not be higher than the maximum rate permitted by Massachusetts law,
as the same may be modified by United States law of general application.
 
     "LIBOR" means, with respect to any Reset Date, the rate (expressed as a
percentage per annum) for deposits in U.S. dollars for a three-month period that
appears on Telerate Page 3750 (as defined below) as of
 
                                      S-15
<PAGE>   16
 
11:00 a.m., London time, on the applicable Determination Date for such Reset
Date. If such rate does not appear on Telerate Page 3750 as of 11:00 a.m.,
London time, on the applicable Determination Date, the Calculation Agent will
request the principal London office of each of four major reference banks in the
London interbank market selected by the Calculation Agent to provide such bank's
offered quotation (expressed as a percentage per annum) to prime banks in the
London interbank market for deposits in U.S. dollars for a three-month period as
of 11:00 a.m., London time, on such Determination Date and in a Representative
Amount (as defined below). If at least two such offered quotations are so
provided, LIBOR will be the arithmetic mean of such quotations. If fewer than
two such quotations are so provided, the Calculation Agent will request each of
three major banks in New York City selected by the Calculation Agent to provide
such bank's rate (expressed as a percentage per annum) for loans in U.S. dollars
to leading European banks for a three-month period as of approximately 11:00
a.m., New York City time, on the applicable Determination Date and in a
Representative Amount. If at least two such rates are so provided, LIBOR will be
the arithmetic mean of such rates. If fewer than two such rates are so provided,
then LIBOR will be LIBOR in effect on the preceding Reset Date.
 
     "Representative Amount" means a principal amount of not less than U.S.
$1,000,000 that is representative for a single transaction in the relevant
market at the relevant time.
 
     "Telerate Page 3750" means the display designated as "Page 3750" on the Dow
Jones Telerate Service, or such other page as may replace Page 3750 on that
service or such other service as may be nominated by the British Bankers'
Association as the information vendor for the purpose of displaying British
Bankers' Association Interest Settlement Rates for U.S. dollar deposits.
 
     Unless the Company shall have otherwise provided 30 days' prior written
notice to the Holders of a series of Notes, the "Calculation Agent" with respect
to such series of Notes will be Shawmut Bank, N.A. Upon the request of any
Holder of a Note, the Calculation Agent will disclose the interest rate then in
effect and, if determined, the interest rate that will become effective as a
result of a determination made for the succeeding Reset Date.
 
     All percentages resulting from any calculation in respect of a Note will be
rounded to the nearest one hundred-thousandth of a percentage point, with five
one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or
.09876545) would be rounded to 9.87655% (or .0987655)), and all dollar amounts
used in or resulting from such calculation in respect of a Note will be rounded
to the nearest cent (with one-half cent rounded upwards).
 
MATURITY AND OPTIONAL REDEMPTION
 
     The Notes will mature on July 13, 1999. However, the Notes are subject to
redemption at the option of the Company, as a whole or from time to time in
part, prior to maturity on any Interest Payment Date on and after April 13,
1995, in the case of the Series A Notes, or on and after July 13, 1996, in the
case of the Series B Notes, upon not less than 30, nor more than 60 days' prior
written notice given to the Holders of the applicable series of Notes as
provided in the Indenture, at a redemption price equal to 100% of the principal
amount thereof, plus accrued and unpaid interest to the date fixed for
redemption; provided, however, that interest payments due on an Interest Payment
Date which is on or prior to the date fixed for redemption will be payable to
the Holders of such Notes (or one or more predecessor Notes) on the Regular
Record Date related to such Interest Payment Date. If less than all of the Notes
are to be redeemed, the particular Notes to be redeemed shall be selected by
such method as the Trustee deems fair and appropriate.
 
     The Notes are not subject to repayment at the option of the Holders
thereof. In addition, the Notes will not be entitled to the benefit of any
sinking fund.
 
ADDITIONAL COVENANTS OF THE COMPANY
 
     Reference is made to the section entitled "Description of Debt Securities"
in the accompanying Prospectus for a description of the covenants applicable to
each series of Notes. Compliance with such covenants, and those described
herein, generally may not be waived by the Company's Board of Trustees or the
Trustee unless the Holders of at least a majority in principal amount of all
outstanding Notes of such series
 
                                      S-16
<PAGE>   17
 
consent to such waiver; provided, however, that the defeasance and covenant
defeasance provisions of the Indenture described under "Description of Debt
Securities -- Discharge, Defeasance and Covenant Defeasance" in the accompanying
Prospectus will apply to each series of Notes.
 
     In addition to the foregoing, the Supplemental Indenture contains the
following additional covenants of the Company for the benefit of the Holders of
each series of Notes:
 
     Limitation on Debt.  The Company covenants and agrees that, so long as any
Notes remain outstanding, at the end of each fiscal year of the Company, it
shall maintain a ratio of (a) total consolidated Debt of the Company to (b)
Total Adjusted Net Worth, of not more than 1.5:1.
 
     Interest Expense Coverage.  The Company covenants and agrees that, for any
fiscal year at the end of which any Notes remain outstanding, it will maintain a
ratio of (a) Total Cash Flow to (b) Total Interest Expense, of not less than
2:1.
 
     Limitation on Unsecured Debt.  The Company covenants and agrees that, so
long as any Notes remain outstanding, at the end of each fiscal year of the
Company, it shall maintain a ratio of (a) Total Unencumbered Assets to (b) total
Unsecured Debt, of not less than 1.4:1.
 
     Interest Rate Protection.  The Company covenants and agrees that, beginning
75 days after the date on which Notes are issued, and for so long thereafter as
any Notes remain outstanding, the Company shall have in effect Interest Rate
Protection Arrangements with respect to a principal amount at least equal to the
Unhedged Balance, such that, at any time, Pro Forma Annualized Interest Charges
shall not exceed an amount equal to nine percent (9%) of the Unhedged Balance.
 
     As used in the Supplemental Indenture, the following terms have the
meanings set forth below:
 
     "Debt" means any indebtedness of the Company or any subsidiary, in respect
of (i) borrowed money evidenced by bonds, notes, debentures or similar
instruments, (ii) indebtedness secured by any mortgage, pledge, lien, charge,
encumbrance or any security interest existing on property owned by the Company
or any subsidiary, (iii) letters of credit or amounts representing the balance
deferred and unpaid of the purchase price of any property except any such
balance that constitutes an accrued expense or trade payable or (iv) Capitalized
Leases, in the case of items of indebtedness under (i) through (iii) above to
the extent that any such items (other than letters of credit) would appear as a
liability on the Company's Consolidated Balance Sheet in accordance with
generally accepted accounting principles applied on a consistent basis ("GAAP"),
and also includes, to the extent not otherwise included, any obligation by the
Company or any subsidiary to be liable for, or to pay, as obligor, guarantor or
otherwise (other than for purposes of collection in the ordinary course of
business), indebtedness of another person (other than the Company or any
subsidiary).
 
     "Floating Rate Investments" means real estate investments owned by the
Company or any subsidiary, valued on the basis of cost of each such asset to the
Company or any subsidiary (less principal amortization, if any) without
reduction for depreciation or adjustments due to asset reappraisals or
otherwise, under which the rental or interest payments to be received by the
Company or such subsidiary are based on fluctuating interest rates, which have
been designated from time to time by the Company to relate to the Notes.
 
     "Interest Rate Protection Arrangements" means interest rate caps, collars,
swaps or similar agreements, the effect of which is to protect the Company from
fluctuations in interest rates, which have been designated from time to time by
the Company to relate to the Notes.
 
     "Pro Forma Annualized Interest Charges" means, at any date, (i) the
weighted average annualized interest rate applicable to the Notes as of that
date multiplied by the Unhedged Balance, less (ii) the annualized amounts which
should be received by the Company under the Interest Rate Protection
Arrangements in effect at that date.
 
     "Total Adjusted Net Worth" means the excess of total assets over total
liabilities of the Company on a consolidated basis, computed in accordance with
GAAP, plus the aggregate amount of accumulated depreciation and adjustments due
to asset reappraisals or otherwise with respect to any such assets since the
acquisition thereof.
 
                                      S-17
<PAGE>   18
 
     "Total Cash Flow" means, for any period, consolidated net income of the
Company, computed in accordance with GAAP, excluding gains (or losses) from debt
restructuring or sales of property, plus (a) Total Interest Expense, (b)
depreciation, amortization or adjustments due to asset reappraisals or
otherwise, and (c) provisions for income taxes, all to the extent deducted in
computing consolidated net income.
 
     "Total Interest Expense" means, for any period, the aggregate amount,
computed in accordance with GAAP consistently applied, of interest payable
during such period by the Company on a consolidated basis in respect of all
Debt, less amortization of capitalized fees, costs and expenses incurred in
connection with such Debt or in connection with interest rate caps, collars,
swaps, or similar agreements in respect of any such Debt, all to the extent
included in the computation of interest payable.
 
     "Total Unencumbered Assets" means the aggregate value of all assets of the
Company and any subsidiary, determined on the basis of cost of each such asset
to the Company or any subsidiary (less principal amortization, if any) without
reduction for depreciation or adjustments due to asset reappraisals or
otherwise, which have not been voluntarily pledged, mortgaged or otherwise
encumbered by the owner thereof to secure Debt.
 
     "Unhedged Balance" means, at any date, the aggregate principal amount of
outstanding Notes, less Floating Rate Investments as of that date; provided,
that if a Floating Rate Investment is terminated, other than by virtue of its
scheduled maturity, within 30 days or less of that date, such terminated
Floating Rate Investment shall be deemed to remain in effect at that date.
 
     "Unsecured Debt" means any Debt of the Company or any subsidiary on a
consolidated basis for which the obligations thereunder are not secured by a
pledge of or other encumbrance on any assets of the Company or any subsidiary.
 
ADDITIONAL EVENT OF DEFAULT
 
     Pursuant to the Supplemental Indenture, the Company has agreed that it
shall also be an Event of Default for each series of Notes if any event of
default under any bond, debenture, note or other evidence of indebtedness of the
Company (including an event of default with respect to any other series of
Securities), or under any mortgage, indenture or other instrument of the Company
under which there may be issued or by which there may be secured or evidenced
any indebtedness of the Company (or by any subsidiary, the repayment of which
the Company has guaranteed or for which the Company is directly responsible or
liable as obligor or guarantor), whether such indebtedness now exists or shall
hereafter be created, shall happen and shall result in an aggregate principal
amount exceeding $20,000,000 of such indebtedness becoming or being declared due
and payable prior to the date on which it would otherwise have become due and
payable, without such indebtedness having been discharged, or such acceleration
having been rescinded or annulled, within a period of 10 days after there shall
have been given, by registered or certified mail, to the Company by the Trustee
or to the Company and the Trustee by the Holders of at least 25% in principal
amount of the outstanding Notes of such series, a written notice specifying such
default and requiring the Company to cause such indebtedness to be discharged or
cause such acceleration to be rescinded or annulled and stating that such notice
is a "Notice of Default" hereunder.
 
BOOK-ENTRY SYSTEM
 
     Each series of Notes will be issued in the form of a single
fully-registered Note in book-entry form (each, a "Global Note") which will be
deposited with, or on behalf of, The Depository Trust Company ("DTC") and
registered in the name of DTC's nominee. Except as set forth below, a Global
Note may not be transferred except as a whole by DTC to a nominee of DTC or by a
nominee of DTC to DTC or another nominee of DTC or by DTC or any such nominee to
a successor of DTC or a nominee of such successor.
 
     So long as DTC or its nominee is the registered owner of a Global Note, DTC
or its nominee, as the case may be, will be considered the sole Holder of the
Notes represented by such Global Note for all purposes under the Indenture.
Except as provided below, owners of beneficial interests in a Global Note will
not be
 
                                      S-18
<PAGE>   19
 
entitled to have Notes represented by such Global Note registered in their
names, will not receive or be entitled to receive physical delivery of Notes of
such series in certificated form and will not be considered the registered
owners or Holders thereof under the Indenture or the Supplemental Indenture.
 
     If (i) DTC is at any time unwilling or unable to continue as depository or
if any time DTC ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, and a successor depository is not appointed by
the Company within 90 days, (ii) an Event of Default under the Indenture or the
Supplemental Indenture with respect to the Notes of either series has occurred
and is continuing and the beneficial owners representing a majority in principal
amount of the series of Notes represented by a Global Note advise DTC to cease
acting as depository or (iii) the Company, in its sole discretion, determines at
any time that all Notes of any series shall no longer be represented by a Global
Note, the Company will issue individual Notes of the applicable series in
certificated form in exchange for the related Global Note. In any such instance,
an owner of a beneficial interest in such Global Note will be entitled to
physical delivery of individual Notes in certificated form of like series and
tenor, equal in principal amount to such beneficial interest and to have such
Notes in certificated form registered in its name. Notes so issued in
certificated form will be issued in denominations of $1,000 or any integral
multiple thereof, and will be issued in registered form only, without coupons.
 
     The following is based on information furnished by DTC:
 
          DTC will act as securities depository for the Notes. The Notes will be
     issued as fully registered securities registered in the name of Cede & Co.
     (DTC's partnership nominee). One fully registered Note certificate is
     issued with respect to each $150 million of principal amount of the
     securities of the applicable series.
 
          DTC is a limited-purpose trust company organized under the New York
     Banking Law, a "banking organization" within the meaning of the New York
     Banking Law, a member of the Federal Reserve System, a "clearing
     corporation" within the meaning of the New York Uniform Commercial Code,
     and a "clearing agency" registered pursuant to the provisions of Section
     17A of the Securities Exchange Act of 1934, as amended. DTC holds
     securities that its participants ("Participants") deposit with DTC. DTC
     also facilitates the settlement among Participants of securities
     transactions, such as transfers and pledges, in deposited securities
     through electronic computerized book-entry changes in Participants'
     accounts, thereby eliminating the need for physical movement of securities
     certificates. Direct Participants include securities brokers and dealers,
     banks, trust companies, clearing corporations and certain other
     organizations ("Direct Participants"). DTC is owned by a number of its
     Direct Participants and by the New York Stock Exchange, Inc., the American
     Stock Exchange, Inc. and the National Association of Securities Dealers,
     Inc. Access to the DTC system is also available to others such as
     securities brokers and dealers, banks and trust companies that clear
     through or maintain a custodial relationship with a Direct Participant,
     either directly or indirectly ("Indirect Participants"). The rules
     applicable to DTC and its Participants are on file with the Securities and
     Exchange Commission.
 
          Purchases of Notes under the DTC system must be made by or through
     Direct Participants, which will receive a credit for the Notes on DTC's
     records. The ownership interest of each actual purchaser of each Note
     ("Beneficial Owner") is in turn recorded on the Direct and Indirect
     Participants' records. A Beneficial Owner does not receive written
     confirmation from DTC of its purchase, but such Beneficial Owner is
     expected to receive a written confirmation providing details of the
     transaction, as well as periodic statements of its holdings, from the
     Direct or Indirect Participant through which such Beneficial Owner entered
     into the transaction. Transfers of ownership interests in Notes are
     accomplished by entries made on the books of Participants acting on behalf
     of Beneficial Owners. Beneficial Owners do not receive certificates
     representing their ownership interests in Notes, except in the event that
     use of the book-entry system for the Notes is discontinued.
 
          To facilitate subsequent transfers, the Notes are registered in the
     name of DTC's partnership nominee, Cede & Co. The deposit of the Notes with
     DTC and their registration in the name of Cede & Co. effects no change in
     beneficial ownership. DTC has no knowledge of the actual Beneficial Owners
     of the Notes; DTC records reflect only the identity of the Direct
     Participants to whose accounts
 
                                      S-19
<PAGE>   20
 
    Notes are credited, which may or may not be the Beneficial Owners. The
    Participants remain responsible for keeping account of their holdings on
    behalf of their customers.
 
          Delivery of notices and other communications by DTC to Direct
     Participants, by Direct Participants to Indirect Participants, and by
     Direct Participants and Indirect Participants to Beneficial Owners are
     governed by arrangements among them, subject to any statutory or regulatory
     requirements as may be in effect from time to time.
 
          Redemption notices shall be sent to Cede & Co. If less than all of the
     Notes of any series represented by a Global Note are to be redeemed, DTC's
     practice is to determine by lot the amount of the interest of each Direct
     Participant to be redeemed.
 
          Neither DTC nor Cede & Co. will consent or vote with respect to the
     Notes. Under its usual procedures, DTC mails a proxy (an "Omnibus Proxy")
     to the issuer as soon as possible after the record date. The Omnibus Proxy
     assigns Cede & Co's consenting or voting rights to those Direct
     Participants to whose accounts the Notes are credited on the record date
     (identified on a list attached to the Omnibus Proxy).
 
          Principal and interest payments on the Notes will be made by the
     Company to the Trustee and from the Trustee to DTC. DTC's practice is to
     credit Direct Participant's accounts on the payable date in accordance with
     their respective holdings as shown on DTC's records unless DTC has reason
     to believe that it will not receive payment on the payable date. Payments
     by Participants to Beneficial Owners will be governed by standing
     instructions and customary practices, as is the case with securities held
     for the accounts of customers in bearer form or registered in "street
     name", and will be the responsibility of such Participant and not of DTC,
     the Trustee or the Company subject to any statutory or regulatory
     requirements as may be in effect from time to time. Payment of principal
     and interest to DTC is the responsibility of the Company or the Trustee,
     disbursement of such payments to Direct Participants is the responsibility
     of DTC, and disbursement of such payments to the Beneficial Owners is the
     responsibility of Direct and Indirect Participants.
 
          DTC may discontinue providing its services as securities depository
     with respect to the Notes at any time by giving reasonable notice to the
     Company or the Trustee. Under such circumstances, in the event that a
     successor securities depository is not appointed, Note certificates are
     required to be printed and delivered.
 
          The Company may decide to discontinue use of the system of book-entry
     transfers through DTC (or a successor securities depository). In that
     event, Note certificates will be printed and delivered.
 
     None of the Company, the Underwriters or the Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial interests in a Global Note, or for
maintaining, supervising or reviewing any records relating to such beneficial
interests.
 
SAME-DAY SETTLEMENT AND PAYMENT
 
     Settlement for each series of Notes will be made by the Underwriters in
immediately available funds. All payments of principal and interest in respect
of the Notes will be made by the Company in immediately available funds.
 
     Secondary trading in long-term notes and debentures of corporate issuers is
generally settled in clearing house or next-day funds. In contrast, the Notes
will trade in DTC's Same-Day Funds Settlement System until maturity or earlier
redemption, as the case may be, or until the Notes are issued in certificated
form, and secondary market trading activity in the Notes will therefore be
required by DTC to settle in immediately available funds. No assurance can be
given as to the effect, if any, of settlement in immediately available funds on
trading activity in the Notes.

</TABLE>
 
     The Underwriting Agreement provides that the obligations of the
Underwriters are subject to certain conditions precedent, and that the
Underwriters will be obligated to purchase all of the Notes if any are
purchased.
 
     The Underwriters have advised the Company that they propose initially to
offer the Notes to the public at the public offering price set forth on the
cover page of this Prospectus Supplement, and to certain dealers at such price
less a concession not in excess of .45% of principal amount thereof. The
Underwriters may allow, and such dealers may reallow, a discount not in excess
of .25% of principal amount to certain other dealers. After the initial public
offering of the Notes, the public offering price, concession and discount may be
changed.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, as amended,
or to contribute to payments the Underwriters may be required to make in respect
thereof.
 
     MLPF&S has been paid, and will be entitled to additional, advisory fees
from the Company upon consummation of the Marriott Transaction. The Company
negotiated with Merrill Lynch Mortgage Capital, Inc. ("MLMCI"), a subsidiary of
MLPF&S, for provision of an interim credit facility to be available in
connection with the Company's consummation of the Marriott Transaction, and, as
a result, MLMCI will be entitled to a fee upon consummation of the Marriott
Transaction. In addition, MLPF&S and MLMCI are both presently entitled to
reimbursement from the Company for their respective out-of-pocket expenses
incurred in advising and assisting the Company in connection with the Marriott
Transaction.
 
                                 LEGAL MATTERS
 
     Certain legal matters with respect to the Notes offered by the Company will
be passed upon for the Company by Sullivan & Worcester, Boston, Massachusetts
and for the Underwriters by Brown & Wood, New York, New York. Sullivan &
Worcester and Brown & Wood will rely, as to all matters of Maryland law, upon
the opinion of Piper & Marbury, Baltimore, Maryland. Barry M. Portnoy, a partner
in the firm of Sullivan & Worcester, is a Trustee of the Company and a director
and 50% shareholder of the Advisor.

NOTE 1 -- BASES OF RECORDING THE ADJUSTMENTS
 
     For the purposes of the unaudited adjusted balance sheet at December 31,
1993 and the unaudited adjusted statement of income for the year ended December
31, 1993, it has been assumed that the following transactions took place on
December 31, 1993 and January 1, 1993, respectively. The adjustments shown on
the face of the unaudited adjusted financial statements are the result of the
cumulative adjustments described in Notes 1(a) through (k) and are summarized in
Note 2.
 
     (a) Marriott Transaction.  On March 17, 1994, the Company entered into an
agreement with Host Marriott Corporation to acquire 14 retirement communities
containing 3,952 residences or beds for $320,000, subject to adjustment. The
communities are triple net leased through December 31, 2013 to a wholly owned
subsidiary of Marriott International, Inc. (Marriott). For purposes of these
unaudited adjusted financial statements, minimum annual rent of $27,645 is used,
which represents a full year's rent for each facility whether or not the
facility was in operation for a full year during 1993. No amount is included in
these statements for additional rent, which pursuant to the leases will commence
in 1994 at the rate of 4.5% of revenues in excess of base amounts determined on
a facility by facility basis. The Company anticipates incurring $5,000 in fees
and expenses related to the Marriott Transaction. The leases are cross-defaulted
and guaranteed by Marriott. The acquisition is expected to close in June 1994.

     (h) Horizon/Greenery Merger.  On February 11, 1994, in connection with the
merger of Greenery into Horizon Healthcare Corporation (Horizon) the Company
sold to Horizon for $28,400, three facilities that had been leased to Greenery.
The Company realized a capital gain of approximately $3,906 on the sale of these
properties. Cumulative net income has been adjusted on the unaudited adjusted
balance sheet by the $3,906 gain on the sale of these properties to exclude this
gain so that the unaudited adjusted statement of income will reflect only normal
results of operations. In addition, Horizon has leased seven facilities
previously leased to Greenery, on substantially similar terms except the leases
were extended through 2005. The Company has also granted Horizon a ten year
option to buy, at the rate of no more than one facility per year, the seven
leased facilities. Also, the Company leased the three remaining Greenery
facilities to a newly formed corporation, Connecticut Subacute Corporation II
(CSCII), an affiliate of HRPT Advisors, Inc. (Advisor). These facilities are
being managed by and the lease payments are guaranteed by Horizon for a term of
up to five years. The terms of these lease arrangements are substantially
similar to the original lease arrangements. In addition, the Company provided
Horizon with $9,400 first mortgage financing for two facilities. One of the
facilities previously was owned by the Company and leased to Greenery. The
mortgage notes bear interest at 11.5% per annum and will mature on December 31,
2000.
 
     Adjustments to the unaudited adjusted financial statements in respect of
these transactions are as follows:

retirement communities (the "Marriott Properties") leased to and operated by a
subsidiary of Marriott International, Inc. (including its subsidiaries,
"Marriott") for $320 million (the "Marriott Transaction"). The Marriott
Properties will be acquired subject to the existing leases which are fully
guaranteed by Marriott. The Marriott Properties contain a total of 3,952
residences or beds and are located in seven states. Upon completion of the
Marriott Transaction: Marriott will be the Company's largest single tenant and
will operate 38% of the Company's investment portfolio of properties; the
Company will have gross real estate investments totalling $831 million, in 152
properties, located in 29 states and operated by 36 separate companies;
approximately 70% of the Company's total investments will be in properties
operated by seven NYSE listed companies; and 97% of the Company's investments
will be in retirement communities, assisted living centers, nursing homes and
other long term care facilities.
 
                                USE OF PROCEEDS
 
     Unless otherwise described in the applicable Prospectus Supplement, the
Company intends to use the net proceeds from the sale of the Offered Securities
for general corporate purposes, which may include the acquisition of, or other
investments in, retirement communities, assisted living centers, nursing homes,
other long term care facilities or other healthcare or healthcare related
properties, and the repayment of indebtedness outstanding at such time. If
Offered Securities are sold prior to the closing of the Marriott Transaction,
all or a portion of the net proceeds from the sale of Offered Securities will be
used to fund the Marriott Transaction. If the Marriott Transaction is
consummated prior to the sale of Offered Securities and the Company utilizes
borrowings to fund the Marriott Transaction, all or a portion of the net
proceeds from the sale of Offered Securities will be used to repay amounts
outstanding under such borrowings, and/or to reduce amounts outstanding under
the Company's credit facilities. In the event that the Marriott Transaction is
not consummated by the Company, net proceeds from the sale of Offered Securities
will be used to reduce amounts outstanding under the Company's revolving credit
facility or for working capital or other general corporate purposes. Pending
utilization as set forth above, the proceeds from the sale of the Offered
Securities will be invested in short term investments, including repurchase
agreements. Such investments may not be investment grade.
 
                         DESCRIPTION OF DEBT SECURITIES
 
     The Debt Securities are to be issued under an Indenture, to be dated as of
June 1, 1994, as amended or supplemented from time to time (the "Indenture"),
between the Company and Shawmut Bank, N.A., as Trustee (the "Trustee"). The
Indenture has been filed as an exhibit to the Registration Statement of which
this Prospectus is a part and is available for inspection at the corporate trust
office of the Trustee at One Federal Street, Boston, Massachusetts or as
described above under "Available Information". The Indenture is subject to, and
governed by, the Trust Indenture Act of 1939, as amended (the "TIA"). The
statements made
 
                                        3
<PAGE>   34
 
hereunder relating to the Indenture and the Debt Securities to be issued
thereunder are summaries of certain provisions thereof and do not purport to be
complete and are subject to, and are qualified in their entirety by reference
to, all provisions of the Indenture and such Debt Securities. All section
references appearing herein are to sections of the Indenture, and capitalized
terms used but not defined herein shall have the respective meanings set forth
in the Indenture.
 
GENERAL
 
     The Debt Securities will be direct, unsecured obligations of the Company.
Except for any series of Debt Securities which is specifically subordinated to
other indebtedness of the Company, the Debt Securities will rank equally with
all other unsecured and unsubordinated indebtedness of the Company. The
Indenture provides that the Debt Securities may be issued without limit as to
aggregate principal amount, in one or more series, in each case as established
from time to time in or pursuant to authority granted by a resolution of the
Board of Trustees of the Company or as established in one or more indentures
supplemental to the Indenture. All Debt Securities of one series need not be
issued at the same time and, unless otherwise provided, a series may be
reopened, without the consent of the Holders of the Debt Securities of such
series, for issuances of additional Debt Securities of such series (Section
301).
 
     The Indenture provides that there may be more than one Trustee thereunder,
each with respect to one or more series of Debt Securities. Any Trustee under
the Indenture may resign or be removed with respect to one or more series of
Debt Securities, and a successor Trustee may be appointed to act with respect to
such series (Section 608). In the event that two or more persons are acting as
Trustee with respect to different series of Debt Securities, each such Trustee
shall be a trustee of a trust under the Indenture separate and apart from the
trust administered by any other Trustee (Section 609), and, except as otherwise
indicated herein, any action described herein to be taken by the Trustee may be
taken by each such Trustee with respect to, and only with respect to, the one or
more series of Debt Securities for which it is Trustee under the Indenture.
 
     Reference is made to the Prospectus Supplement relating to the series of
Debt Securities being offered for the specific terms thereof, including:
 
      (1) the title of such Debt Securities;
 
      (2) the aggregate principal amount of such Debt Securities and any limit
          on such aggregate principal amount;
 
      (3) the percentage of the principal amount at which such Debt Securities
          will be issued and, if other than the principal amount thereof, the
          portion of the principal amount thereof payable upon declaration of
          acceleration of the maturity thereof, or (if applicable) the portion
          of the principal amount of such Debt Securities which is convertible
          into Common Shares or Preferred Shares, or the method by which any
          such portion shall be determined;
 
      (4) the date or dates, or the method for determining such date or dates,
          on which the principal of such Debt Securities will be payable;
 
      (5) the rate or rates (which may be fixed or variable), or the method by
          which such rate or rates shall be determined, at which such Debt
          Securities will bear interest, if any;
 
      (6) the date or dates, or the method for determining such date or dates,
          from which any such interest will accrue, the Interest Payment Dates
          on which any such interest will be payable, the Regular Record Dates
          for such Interest Payment Dates, or the method by which such Dates
          shall be determined, the Person to whom such interest shall be
          payable, and the basis upon which interest shall be calculated if
          other than that of a 360-day year of twelve 30-day months;
 
      (7) the place or places where the principal of (and premium, if any) and
          interest, if any, on such Debt Securities will be payable, such Debt
          Securities may be surrendered for conversion or registration of
          transfer or exchange and notices or demands to or upon the Company in
          respect of such Debt Securities and the Indenture may be served.

      (8) the period or periods within which, or the date or dates on which, the
          price or prices at which and the terms and conditions upon which such
          Debt Securities may be redeemed, as a whole or in part, at the option
          of the Company, if the Company is to have such an option;
 
      (9) the obligation, if any, of the Company to redeem, repay or repurchase

     (11) whether the amount of payments of principal of (and premium, if any)
          or interest, if any, on such Debt Securities may be determined with
          reference to an index, formula or other method (which index, formula
          or method may, but need not be, based on a currency, currencies,
          currency unit or units or composite currency or currencies) and the
          manner in which such amounts shall be determined;
 
     (12) any additions to, modifications of or deletions from the terms of such
          Debt Securities with respect to the Events of Default or covenants set
          forth in the Indenture;
 
     (13) whether such Debt Securities will be issued in certificated or
          book-entry form;
 
     (14) whether such Debt Securities will be in registered or bearer form and,
          if in registered form, the denominations thereof if other than $1,000
          and any integral multiple thereof and, if in bearer form, the
          denominations thereof and terms and conditions relating thereto;
 
     (15) the applicability, if any, of the defeasance and covenant defeasance
          provisions of Article XIV of the Indenture;
 
     (16) if such Debt Securities are to be issued upon the exercise of debt
          warrants, the time, manner and place for such Debt Securities to be

          and conditions upon which such conversion will be effected, including,
          without limitation, the initial conversion price or rate, the
          conversion period and, in connection with the preservation of the
          Company's status as a REIT, limitations on the ownership of the Common
          Shares or Preferred Shares into which such Debt Securities are
          convertible;
 
     (18) the terms and conditions, if any, upon which such Debt Securities may
          be subordinated to other indebtedness of the Company;
 
     (19) whether and under what circumstances the Company will pay Additional
          Amounts as contemplated in the Indenture on such Debt Securities in
          respect of any tax, assessment or governmental charge and, if so,
          whether the Company will have the option to redeem such Debt
          Securities in lieu of making such payment; and
 
     (20) any other terms of such Debt Securities not inconsistent with the
          provisions of the Indenture (Section 301).
 
     The Debt Securities may provide for less than the entire principal amount
thereof to be payable upon declaration of acceleration of the maturity thereof
("Original Issue Discount Securities"). Special U.S. federal income tax,
accounting and other considerations applicable to the Original Issue Discount
Securities will be described in the applicable Prospectus Supplement.
 
     The Indenture does not contain any provisions that would limit the ability
of the Company to incur indebtedness or that would afford Holders of Debt
Securities protection in the event of a highly leveraged or
 
                                        5
<PAGE>   36
 
similar transaction involving the Company. However, restrictions on ownership
and transfers of the Common Shares and Preferred Shares, designed to preserve
its status as a REIT, may prevent or hinder a change of control. Reference is
made to the applicable Prospectus Supplement for information with respect to any
deletions from, modifications of or additions to the Events of Default or
covenants of the Company that are described below, including any addition of a
covenant or other provision providing event risk or similar protection.
 
DENOMINATIONS, INTEREST, REGISTRATION AND TRANSFER
 
     Unless otherwise described in the applicable Prospectus Supplement, the
Debt Securities of any series will be issuable in denominations of $1,000 and
integral multiples thereof (Section 302).
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
principal of (and premium, if any) and interest on any series of Debt Securities
will be payable at the corporate trust office of the Trustee, initially located
at One Federal Street, Boston, Massachusetts, provided that, at the option of
the Company, payment of interest may be made by check mailed to the address of
the Person entitled thereto as it appears in the Security Register or by wire
transfer of funds to such Person at an account maintained within the United
States (Sections 301, 305, 307 and 1002).
 
     Any interest not punctually paid or duly provided for on any Interest
Payment Date with respect to a Debt Security ("Defaulted Interest") will
forthwith cease to be payable to the Holder on the applicable Regular Record
Date and may either be paid to the person in whose name such Debt Security is
registered at the close of business on a special record date (the "Special
Record Date") for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to the Holder of such Debt Security not
less than 10 days prior to such Special Record Date, or may be paid at any time
in any other lawful manner, all as more completely described in the Indenture
(Sections 101 and 307).
 
     Subject to certain limitations imposed upon Debt Securities issued in
book-entry form, the Debt Securities of any series will be exchangeable for
other Debt Securities of the same series and of a like aggregate principal
amount and tenor of different authorized denominations upon surrender of such
Debt Securities at the corporate trust office of the Trustee referred to above.
In addition, subject to certain limitations imposed upon Debt Securities issued
in book-entry form, the Debt Securities of any series may be surrendered for
conversion or registration of transfer thereof at the corporate trust office of
the Trustee referred to above. Every Debt Security surrendered for conversion,
registration of transfer or exchange shall be duly endorsed or accompanied by a
written instrument of transfer. No service charge will be made for any
registration of transfer or exchange of any Debt Securities, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith (Section 305). If the applicable
Prospectus Supplement refers to any transfer agent (in addition to the Trustee)
initially designated by the Company with respect to any series of Debt
Securities, the Company may at any time rescind the designation of any such
transfer agent or approve a change in the location through which any such
transfer agent acts, except that the Company will be required to maintain a
transfer agent in each Place of Payment for such series. The Company may at any
time designate additional transfer agents with respect to any series of Debt
Securities (Section 1002).
 
     Neither the Company nor the Trustee shall be required to (i) issue,
register the transfer of or exchange Debt Securities of any series during a
period beginning at the opening of business 15 days before any selection of Debt
Securities of that series to be redeemed and ending at the close of business of
the day of mailing of the relevant notice of redemption; (ii) register the
transfer of or exchange any Debt Security, or portion thereof, called for
redemption, except the unredeemed portion of any Debt Security being redeemed in
part; or (iii) issue, register the transfer of or exchange any Debt Security
which has been surrendered for repayment at the option of the Holder, except
that portion, if any, of such Debt Security which is not to be so repaid
(Section 305).

MERGER, CONSOLIDATION OR SALE
 
     The Company may consolidate with, or sell, lease or convey all or
substantially all of its assets to, or merge with or into, any other trust or
corporation, provided that (a) either the Company shall be the continuing
entity, or the successor (if other than the Company) formed by or resulting from
any such consolidation or merger or which shall have received the transfer of
such assets shall expressly assume payment of the principal of (and premium, if
any) and interest on all of the Debt Securities and the due and punctual
performance and observance of all of the covenants and conditions contained in
the Indenture; (b) immediately after giving effect to such transaction and
treating any indebtedness which becomes an obligation of the Company or any
Subsidiary as a result thereof as having been incurred by the Company or such
Subsidiary at the time of such transaction, no Event of Default under the
Indenture, and no event which, after notice or the lapse of time, or both, would
become such an Event of Default, shall have occurred and be continuing; and (c)
an officer's certificate and legal opinion covering such conditions shall be
delivered to the Trustee (Sections 801 and 803).
 
CERTAIN COVENANTS
 
     Existence.  Except as permitted under "Merger, Consolidation or Sale," the
Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its existence, rights (declaration and statutory) and
franchises; provided, however, that the Company shall not be required to
preserve any right or franchise if it determines that the preservation thereof
is no longer desirable in the conduct of its business and that the loss thereof
is not disadvantageous in any material respect to the Holders of the Debt
Securities (Section 1004).
 
     Provision of Financial Information.  Whether or not the Company is subject
to Section 13 or 15(d) of the Exchange Act, the Company will, to the extent
permitted under the Exchange Act, file with the Commission the annual reports,
quarterly reports and other documents which the Company would have been required
to file with the Commission pursuant to such Section 13 or 15(d) (the "Financial
Statements") if the Company were so subject, such documents to be filed with the
Commission on or prior to the respective dates (the "Required Filing Dates") by
which the Company would have been required so to file such documents if the
Company were so subject. The Company will also in any event (x) file with the
Trustee copies of the annual reports, quarterly reports and other documents
which the Company would have been required to file with the Commission pursuant
to Section 13 or 15(d) of the Exchange Act if the Company were subject to such
Sections and (y) if filing such documents by the Company with the Commission is
not permitted under the Exchange Act, promptly upon written request and payment
of the reasonable cost of duplication and delivery, supply copies of such
documents to any prospective Holder (Section 1005).
 
     Other.  Reference is made to the applicable Prospectus Supplement for
information with respect to any additional covenants specific to a particular
series of Debt Securities.
 
EVENT OF DEFAULT, NOTICE AND WAIVER
 
     The Indenture provides that the following events are "Events of Default"
with respect to any series of Debt Securities issued thereunder: (a) default for
30 days in the payment of any installment of interest on any Debt Security of
such series; (b) default in the payment of the principal of (or premium, if any,
on) any Debt Security of such series at its Maturity; (c) default in making any
sinking fund payment as required for any Debt Security of such series; (d)
default in the performance of any other covenant or warranty of the Company
contained in the Indenture (other than a covenant or warranty, added to the
Indenture solely for the benefit of a series of Debt Securities issued
thereunder other than such series), continued for 60 days after written notice
as provided in the Indenture; (e) default in the payment of an aggregate
principal amount exceeding $10,000,000 of any evidence of indebtedness of the
Company or any mortgage, indenture or other instrument under which such
indebtedness is issued or by which such indebtedness is secured, such default
having occurred after the expiration of any applicable grace period and having
resulted in the acceleration of the maturity of such indebtedness, but only if
such indebtedness is not discharged or such acceleration is not rescinded or
annulled; (f) certain events of bankruptcy, insolvency or reorganization, or
court appointment of
 
                                        7
<PAGE>   38
 
a receiver, liquidator or trustee of the Company or any Significant Subsidiary
or the property of either; (g) the acquisition by any Person (including any
affiliates of such Person) of 20% or more of the Company's Common Shares, unless
the Company's Board of Trustees shall have first approved of such acquisition;
and (h) any other Event of Default provided with respect to a particular series
of Debt Securities (Section 501). The term "Significant Subsidiary" means each
significant subsidiary (as defined in Regulation S-X promulgated under the
Securities Act) of the Company.
 
     If an Event of Default under the Indenture with respect to Debt Securities
of any series at the time Outstanding occurs and is continuing, then in every
such case the Trustee or the Holders of not less than a majority in principal
amount of the Outstanding Debt Securities of that series may declare the
principal amount (or, if the Debt Securities of that series are Original Issue
Discount Securities or Indexed Securities, such portion of the principal amount
as may be specified in the terms thereof) of all of the Debt Securities of that
series to be due and payable immediately by written notice thereof to the
Company (and to the Trustee if given by the Holders). However, any time after
such a declaration of acceleration with respect to Debt Securities of such
series (or of all Debt Securities then Outstanding under the Indenture, as the
case may be) has been made, but before a judgment or decree for payment of the
money due has been obtained by the Trustee, the Holders of not less than a
majority in principal amount of Outstanding Debt Securities of such series (or
of all Debt Securities then Outstanding under the Indenture, as the case may be)
may rescind and annul such declaration and its consequences if (a) the Company
shall have deposited with the Trustee all required payments of the principal of
(and premium, if any) and interest on the Debt Securities of such series (or of
all Debt Securities then outstanding under the Indenture, as the case may be),
plus certain fees, expenses, disbursements and advances of the Trustee and (b)
all Events of Default, other than the non-payment of accelerated principal (or
specified portion thereof), with respect to Debt Securities of such series (or
of all Debt Securities then Outstanding under the Indenture, as the case may be)
have been cured or waived as provided in the Indenture (Section 502). The
Indenture also provides that the Holders of not less than a majority in
principal amount of the Outstanding Debt Securities of any series (or of all
Debt Securities then Outstanding under the Indenture, as the case may be) may
waive any past default with respect to such series and its consequences, except
a default (x) in the payment of the principal of (or premium, if any) or
interest on any Debt Security of such series or (y) in respect of a covenant or
provision contained in the Indenture that cannot be modified or amended without
the consent of the Holder of each Outstanding Debt Security affected thereby
(Section 513).
 
     The Trustee is required to give notice to the Holders of Debt Securities
within 90 days of a default under the Indenture; provided, however, that the
Trustee may withhold notice to the Holders of any series of Debt Securities of
any default with respect to such series (except a default in the payment of the
principal of (or premium, if any) or interest on any Debt Security of such
series or in the payment of any sinking fund installment in respect of any Debt
Security of such series) if the Responsible Officers of the Trustee consider
such withholding to be in the interest of such Holders (Section 601).
 
     The Indenture provides that no Holders of Debt Securities of any series may
institute any proceedings, judicial or otherwise, with respect to the Indenture
or for any remedy thereunder, except in the case of failure of the Trustee, for
60 days, to act after it has received a written request to institute proceedings
in respect of an Event of Default from the Holders of not less than a majority
in principal amount of the Outstanding Debt Securities of any series, as well as
an offer of reasonable indemnity (Section 507). This provision will not prevent,
however, any Holder of Debt Securities from instituting suit for the enforcement
of payment of the principal of (and premium, if any) and interest on such Debt
Securities at the respective due dates thereof (Section 508).
 
     Subject to provisions in the Indenture relating to its duties in case of
default, the Trustee is under no obligation to exercise any of its rights or
powers under the Indenture at the request or direction of any Holders of any
series of Debt Securities then Outstanding under the Indenture, unless such
Holders shall have offered to the Trustee reasonable security or indemnity
(Section 602). The Holders of not less than a majority in principal amount of
the Outstanding Debt Securities of any series (or of all Debt Securities then
Outstanding under the Indenture, as the case may be) shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or of exercising any trust or power
 
                                        8
<PAGE>   39
 
conferred upon the Trustee. However, the Trustee may refuse to follow any
direction which is in conflict with any law or the Indenture, which may involve
the Trustee in personal liability or which may be unduly prejudicial to the
Holders of Debt Securities of such series not joining therein (Section 512).
 
     Within 120 days after the close of each fiscal year, the Company must
deliver to the Trustee a certificate, signed by one of several specified
officers, stating whether or not such officer has knowledge of any default under
the Indenture and, if so, specifying each such default and the nature and status
thereof (Section 1006).
 
MODIFICATION OF THE INDENTURE
 
     Modifications and amendments of the Indenture may be made only with the
consent of the Holders of not less than a majority in principal amount of all
Outstanding Debt Securities which are affected by such modification or
amendment; provided, however, that no such modification or amendment may,
without the consent of the Holder of each such Debt Security affected thereby,
(a) change the Stated Maturity of the principal of, or any installment of
interest (or premium, if any) on, any such Debt Security; (b) reduce the
principal amount of, or the rate or amount of interest on, or any premium
payable on redemption of, any such Debt Security, or reduce the amount of
principal of an Original Issue Discount Security that would be due and payable
upon declaration of acceleration of the maturity thereof or would be provable in
bankruptcy, or adversely affect any right of repayment of the Holder of any such
Debt Security; (c) change the Place of Payment, or the coin or currency, for
payment of principal of, premium, if any, or interest on any such Debt Security;
(d) impair the right to institute suit for the enforcement of any payment on or
with respect to any such Debt Security; (e) reduce the above-stated percentage
of Outstanding Debt Securities of any series necessary to modify or amend the
Indenture, to waive compliance with certain provisions thereof or certain
defaults and consequences thereunder or to reduce the quorum or voting
requirements set forth in the Indenture; or (f) modify any of the foregoing
provisions or any of the provisions relating to the waiver of certain past
defaults or certain covenants, except to increase the required percentage to
effect such action or to provide that certain other provisions may not be
modified or waived without the consent of the Holder of such Debt Security
(Section 902).
 
     The Holders of not less than a majority in principal amount of Outstanding
Debt Securities have the right to waive compliance by the Company with certain
covenants in the Indenture (Section 1008).
 
     Modifications and amendments of the Indenture may be made by the Company
and the Trustee without the consent of any Holder of Debt Securities for any of
the following purposes: (i) to evidence the succession of another Person to the
Company as obligor under the Indenture; (ii) to add to the covenants of the
Company for the benefit of the Holders of all or any series of Debt Securities
or to surrender any right or power conferred upon the Company in the Indenture;
(iii) to add Events of Default for the benefit of the Holders of all or any
series of Debt Securities; (iv) to add or change any provisions of the Indenture
to facilitate the issuance of, or to liberalize certain terms of, Debt
Securities in bearer form, or to permit or facilitate the issuance of Debt
Securities in uncertified form, provided that such action shall not adversely
affect the interests of the Holders of the Debt Securities of any series in any
material respect; (v) to change or eliminate any provisions of the Indenture,
provided that any such change or elimination shall become effective only when
there are no Debt Securities Outstanding of any series created prior thereto
which are entitled to the benefit of such provision; (vi) to secure the Debt
Securities; (vii) to establish the form or terms of Debt Securities of any
series, including the provision and procedures, if applicable, for the
conversion of such Debt Securities into Common Shares or Preferred Shares;
(viii) to provide for the acceptance of appointment by a successor Trustee or
facilitate the administration of the trusts under the Indenture by more than one
Trustee; (ix) to cure any ambiguity, defect or inconsistency in the Indenture,
provided that such action shall not adversely affect the interests of Holders of
Debt Securities of any series in any material respect; or (x) to supplement any
of the provisions of the Indenture to the extent necessary to permit or
facilitate defeasance and discharge of any series of such Debt Securities,
provided that such action shall not adversely affect the interests of the
Holders of the Debt Securities of any series in any material respect (Section
901).
 
     The Indenture provides that in determining whether the Holders of the
requisite principal amount of Outstanding Debt Securities of a series have given
any request, demand, authorization, direction, notice,
 
                                        9
<PAGE>   40
 
consent or waiver thereunder or whether a quorum is present at a meeting of
Holders of Debt Securities, (i) the principal amount of an Original Issue
Discount Security that shall be deemed to be outstanding shall be the amount of
the principal thereof that would be due and payable as of the date of such
determination upon declaration of acceleration of the maturity thereof, (ii) the
principal amount of a Debt Security denominated in a Foreign Currency that shall
be deemed outstanding shall be the U.S. dollar equivalent, determined on the
issue date for such Debt Security, of the principal amount (or, in the case of
an Original Issue Discount Security, the U.S. dollar equivalent on the issue
date of such Debt Security of the amount determined as provided in (i) above),
(iii) the principal amount of an Indexed Security that shall be deemed
outstanding shall be the principal face amount of such Indexed Security at
original issuance, unless otherwise provided with respect to such Indexed
Security pursuant to Section 301 of the Indenture, and (iv) Debt Securities
owned by the Company or any other obligor upon the Debt Securities or any
Affiliate of the Company or of such other obligor shall be disregarded (Section
101).
 
     The Indenture contains provisions for convening meetings of the Holders of
Debt Securities of a series (Section 1501). A meeting may be called at any time
by the Trustee, and also, upon request, by the Company or the Holders of at
least 25% in principal amount of the Outstanding Debt Securities of such series,
in any such case upon notice given as provided in the Indenture (Section 1502).
Except for any consent that must be given by the Holder of each Debt Security
affected by certain modifications and amendments of the Indenture, any
resolution presented at a meeting or adjourned meeting duly reconvened at which
a quorum is present may be adopted by the affirmative vote of the Holders of a
majority in principal amount of the Outstanding Debt Securities of that series;
provided, however, that, except as referred to above, any resolution with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that may be made, given or taken by the Holders of a
specified percentage, which is less than a majority, in principal amount of the
Outstanding Debt Securities of a series may be adopted at a meeting or adjourned
meeting duly reconvened at which a quorum is present by the affirmative vote of
the Holders of such Debt Securities of that series. Any resolution passed or
decision taken at any meeting of Holders of Debt Securities of any series duly
held in accordance with the Indenture will be binding on all Holders of Debt
Securities of that series. The quorum at any meeting called to adopt a
resolution, and at any reconvened meeting, will be Persons holding or
representing a majority in principal amount of the Outstanding Debt Securities
of a series; provided, however, that if any action is to be taken at such
meeting with respect to a consent or waiver which may be given by the Holders of
not less than a specified percentage in principal amount of the Outstanding Debt
Securities of a series, the Persons holding or representing such specified
percentage in principal amount of the Outstanding Debt Securities of such series
will constitute a quorum (Section 1504).
 
     Notwithstanding the foregoing provisions, if any action is to be taken at a
meeting of Holders of Debt Securities of any series with respect to any request,
demand, authorization, direction, notice, consent, waiver or other action that
the Indenture expressly provides may be made, given or taken by the Holders of a
specified percentage in principal amount of all Outstanding Debt Securities
affected thereby, or of the Holders of such series and one or more additional
series: (i) there shall be no minimum quorum requirement for such meeting and
(ii) the principal amount of the Outstanding Debt Securities of such series that
vote in favor of such request, demand, authorization, direction, notice,
consent, waiver or other action shall be taken into account in determining
whether such request, demand, authorization, direction, notice, consent, waiver
or other action has been made, given or taken under the Indenture (Section
1504).
 
DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE
 
     The Company may discharge certain obligations to Holders of any series of
Debt Securities that have not already been delivered to the Trustee for
cancellation and that either have become due and payable or will become due and
payable within one year (or scheduled for redemption within one year) by
irrevocably depositing with the Trustee, in trust, funds in such currency or
currencies, currency unit or units or composite currency or currencies in which
such Debt Securities are payable in an amount sufficient to pay the entire
indebtedness on such Debt Securities in respect of principal (and premium, if
any) and interest to the date of such deposit (if such Debt Securities have
become due and payable) or to the Stated Maturity or Redemption Date, as the
case may be (Section 401).
 
                                       10
<PAGE>   41
 
     The Indenture provides that, if the provisions of Article Fourteen are made
applicable to the Debt Securities of or within any series pursuant to Section
301 of the Indenture, the Company may elect either (a) to defease and be
discharged from any and all obligations with respect to such Debt Securities
(except for the obligation to pay Additional Amounts, if any, upon the
occurrence of certain events of tax, assessment or governmental charge with
respect to payments on such Debt Securities and the obligations to register the
transfer or exchange of such Debt Securities, to replace temporary or mutilated,
destroyed, lost or stolen Debt Securities, to maintain an office or agency in
respect of such Debt Securities and to hold moneys for payment in trust)
("defeasance") (Section 1402) or (b) to be released from its obligations with
respect to such Debt Securities under Sections 1004 and 1005, inclusive, of the
Indenture (being the restrictions described under "Certain Covenants") or, if
provided pursuant to Section 301 of the Indenture, its obligations with respect
to any other covenant, and any omission to comply with such obligations shall
not constitute a default or an Event of Default with respect to such Debt
Securities ("covenant defeasance") (Section 1403), in either case upon the
irrevocable deposit by the Company with the Trustee, in trust, of an amount, in
such currency or currencies, currency unit or units or composite currency or
currencies in which such Debt Securities are payable at Stated Maturity, or
Government Obligations (as defined below), or both, applicable to such Debt
Securities which through the scheduled payment of principal and interest in
accordance with their terms will provide money in an amount sufficient to pay
the principal of (and premium, if any) and interest on such Debt Securities, and
any mandatory sinking fund or analogous payments thereon, on the scheduled due
dates therefor.
 
     Such a trust may only be established if, among other things, the Company
has delivered to the Trustee an Opinion of Counsel (as specified in the
Indenture) to the effect that the Holders of such Debt Securities will not
recognize income, gain or loss for U.S. federal income tax purposes as a result
of such defeasance or covenant defeasance and will be subject to U.S. federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such defeasance or covenant defeasance had not
occurred, and such Opinion of Counsel, in the case of defeasance, must refer to
and be based upon a ruling of the Internal Revenue Service or a change in
applicable United States federal income tax law occurring after the date of the
Indenture (Section 1404).
 
     "Government Obligations" means securities which are (i) direct obligations
of the United States of America or the government which issued the Foreign
Currency in which the Debt Securities of a particular series are payable, for
the payment of which its full faith and credit is pledged or (ii) obligations of
a Person controlled or supervised by and acting as an agency or instrumentality
of the United States of America or such government which issued the Foreign
Currency in which the Debt Securities of such series are payable, the payment of
which is unconditionally guaranteed as a full faith and credit obligation by the
United States of America or such other government, which, in either case, are
not callable or redeemable at the option of the issuer thereof, and shall also
include a depository receipt issued by a bank or trust company as custodian with
respect to any such Government Obligation or a specific payment of interest on
or principal of any such Government Obligation held by such custodian for the
account of the holder of a depository receipt, provided that (except as required
by law) such custodian is not authorized to make any deduction from the amount
payable to the holder of such depository receipt from any amount received by the
custodian in respect of the Government Obligation or the specific payment of
interest on or principal of the Government Obligation evidenced by such
depository receipt (Section 101).
 
     Unless otherwise provided in the applicable Prospectus Supplement, if after
the Company has deposited funds and/or Government Obligations to effect
defeasance or covenant defeasance with respect to Debt Securities of any series,
(a) the Holder of a Debt Security of such series is entitled to, and does, elect
pursuant to Section 301 of the Indenture or the terms of such Debt Security to
receive payment in a currency, currency unit or composite currency other than
that in which such deposit has been made in respect of such Debt Security, or
(b) a Conversion Event (as defined below) occurs in respect of the currency,
currency unit or composite currency in which such deposit has been made, the
indebtedness represented by such Debt Security shall be deemed to have been, and
will be, fully discharged and satisfied through the payment of the principal of
(and premium, if any) and interest on such Debt Security as they become due out
of the proceeds yielded by converting the amount so deposited in respect of such
Debt Security into the currency, currency unit or
 
                                       11
<PAGE>   42
 
composite currency in which such Debt Security becomes payable as a result of
such election or such cessation of usage based on the applicable market exchange
rate (Section 1405). "Conversion Event" means the cessation of use of (i) a
currency, currency unit or composite currency both by the government of the
country which issued such currency and for the settlement of transactions by a
central bank or other public institutions or within the international banking
community, (ii) the ECU both within the European Monetary System and for the
settlement of transactions by public institutions of or within the European
Communities or (iii) any currency unit or composite currency other than the ECU
for the purposes for which it was established. Unless otherwise provided in the
applicable Prospectus Supplement, all payments of principal of (and premium, if
any) and interest on any Debt Security that is payable in a Foreign Currency
that cease to be used by its government of issuance shall be made in U.S.
dollars (Section 101).
 
     In the event the Company effects covenant defeasance with respect to any
Debt Securities and such Debt Securities are declared due and payable because of
the occurrence of any Event of Default other than the Event of Default described
in clause (d) under "Events of Default, Notice and Waiver" with respect to
Sections 1004 and 1005, inclusive, of the Indenture (which Sections would no
longer be applicable to such Debt Securities) or described in clause (h) under
"Events of Default, Notice and Waiver" with respect to any other covenant as to
which there has been covenant defeasance, the amount in such currency, currency
unit or composite currency in which such Debt Securities are payable, and
Government Obligations on deposit with the Trustee, will be sufficient to pay
amounts due on such Debt Securities at the time of their Stated Maturity but may
not be sufficient to pay amounts due on such Debt Securities at the time of the
acceleration resulting from such Event of Default. However, the Company would
remain liable to make payment of such amounts due at the time of acceleration.
 
     The applicable Prospectus Supplement may further describe the provisions,
if any, permitting such defeasance or covenant defeasance, including any
modifications to the provisions described above, with respect to the Debt
Securities of or within a particular series.
 
CONVERSION RIGHTS
 
     The terms and conditions, if any, upon which the Debt Securities are
convertible into Common Shares or Preferred Shares will be set forth in the
applicable Prospectus Supplement relating thereto. Such terms will include
whether such Debt Securities are convertible into Common Shares or Preferred
Shares, the conversion price (or manner of calculation thereof), the conversion
period, provisions as to whether conversion will be at the option of the Holders
or the Company, the events requiring an adjustment of the conversion price and
provisions affecting conversion in the event of the redemption of such Debt
Securities.
 
SUBORDINATION
 
     The terms and conditions, if any, upon which the Debt Securities are
subordinated to other indebtedness of the Company will be set forth in the
applicable Prospectus Supplement relating thereto. Such terms will include a
description of the indebtedness ranking senior to the Debt Securities, the
restrictions on payments to the Holders of such Debt Securities while a default
with respect to such senior indebtedness in continuing, the restrictions, if
any, on payments to the Holders of such Debt Securities following an Event of
Default, and provisions requiring Holders of such Debt Securities to remit
certain payments to holders of senior indebtedness.
 
GLOBAL SECURITIES
 
     The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities (the "Global Securities") that will be
deposited with, or on behalf of, a depositary (the "Depositary") identified in
the applicable Prospectus Supplement relating to such series. Global Securities
may be issued in either registered or bearer form and in either temporary or
permanent form. The specific terms of the depositary arrangement with respect to
a series of Debt Securities will be described in the applicable Prospectus
Supplement relating to such series.

          dividend rights and rights upon liquidation, dissolution or winding up
          of the affairs of the Company; and
 
     (14) any limitations on direct or beneficial ownership and restrictions on
          transfer, in each case as may be appropriate to preserve the status of
          the Company as a REIT.
 
RANK
 
     Unless otherwise determined by the Board of Trustees of the Company and
specified in the Prospectus Supplement, it is expected that the Preferred Shares
will, with respect to dividend rights and rights upon liquidation, dissolution
or winding up of the Company, rank (i) senior to all Common Shares, and to all
equity securities ranking junior to such Preferred Shares; (ii) on a parity with
all equity securities issued by the Company the terms of which specifically
provide that such equity securities rank on a parity with the Preferred Shares;
and (iii) junior to all equity securities issued by the Company the terms of
which specifically provide that such equity securities rank senior to the
Preferred Shares.
 
DIVIDENDS
 
     Holders of Preferred Shares of each series shall be entitled to receive,
when, as and if declared by the Board of Trustees of the Company, out of assets
of the Company legally available for payment, cash dividends at such rates and
on such dates as will be set forth in the applicable Prospectus Supplement. Each
such dividend shall be payable to holders of record as they appear on the stock
transfer books of the Company on such record dates as shall be fixed by the
Board of Trustees of the Company.
 
     Dividends on any series of the Preferred Shares may be cumulative or
non-cumulative, as provided in the applicable Prospectus Supplement. Dividends,
if cumulative, will be cumulative from and after the date set forth in the
applicable Prospectus Supplement. If the Board of Trustees of the Company fails
to declare a dividend payable on a dividend payment date on any series of the
Preferred Shares for which dividends are noncumulative, then the holders of such
series of the Preferred Shares will have no right to receive a dividend in
respect of the dividend period ending on such dividend payment date, and the
Company will have no obligation to pay the dividend accrued for such period,
whether or not dividends on such series are declared payable on any future
dividend payment date.
 
     If Preferred Shares of any series are outstanding, no full dividends shall
be declared or paid or set apart for payment on the preferred shares of the
Company of any other series ranking, as to dividends, on a parity
 
                                       14
<PAGE>   45
 
with or junior to the Preferred Shares of such series for any period unless (i)
if such series of Preferred Shares has a cumulative dividend, full cumulative
dividends have been or contemporaneously are declared and paid or declared and a
sum sufficient for the payment thereof set apart for such payment on the
Preferred Shares of such series for all past dividend periods and the then
current dividend period or (ii) if such series of Preferred Shares does not have
a cumulative dividend, full dividends for the then current dividend period have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof set apart for such payment on the Preferred Shares of
such series. When dividends are not paid in full (or a sum sufficient for such
full payment is not so set apart) upon the Preferred Shares of any series and
the shares of any other series of preferred shares ranking on a parity as to
dividends with the Preferred Shares of such series, all dividends declared upon
Preferred Shares of such series and any other series of preferred shares shall
in all cases bear to each other the same ratio that accrued dividends per share
on the Preferred Shares of such series (which shall not include any accumulation
in respect of unpaid dividends for prior dividend periods if such Preferred
Shares do not have a cumulative dividend) and such other series of preferred
shares bear to each other. No interest, or sum of money in lieu of interest,
shall be payable in respect of any dividend payment or payments on Preferred
Shares of such series which may be in arrears.
 
     Except as provided in the immediately preceding paragraph, unless (i) if
such series of Preferred Shares has a cumulative dividend, full cumulative
dividends on the Preferred Shares of such series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the repayment thereof
set apart for payment for all past dividend periods and the then current
dividend period and (ii) if such series of Preferred Shares does not have a
cumulative dividend, full dividends on the Preferred Shares of such series have
been or contemporaneously are declared and paid or declared and a sum sufficient
for the payment thereof set apart for payment for the then current dividend
period, no dividends (other than in Common Shares or other capital stock ranking
junior to the Preferred Shares of such series as to dividends and upon
liquidation) shall be declared or paid or set aside for payment or other
distribution shall be declared or made upon the Common Shares or any other
capital stock of the Company ranking junior to or on a parity with the Preferred
Shares of such series as to dividends or upon liquidation, nor shall any Common
Shares or any other capital stock of the Company ranking junior to or on a
parity with the Preferred Shares of such series as to dividends or upon
liquidation be redeemed, purchased or otherwise acquired for any consideration
(or any moneys be paid to or made available for a sinking fund for the
redemption of any shares of any such stock) by the Company (except by conversion
into or exchange for other capital stock of the Company ranking junior to the
Preferred Shares of such series as to dividends and upon liquidation).
 
     Any dividend payment made on shares of a series of Preferred Shares shall
first be credited against the earliest accrued but unpaid dividend due with
respect to shares of such series which remains payable.
 
REDEMPTION
 
     If so provided in the applicable Prospectus Supplement, the Preferred
Shares will be subject to mandatory redemption or redemption at the option of
the Company, as a whole or in part, in each case upon the terms, at the times
and at the redemption prices set forth in such Prospectus Supplement.
 
     The Prospectus Supplement relating to a series of Preferred Shares that is
subject to mandatory redemption will specify the number of such Preferred Shares
that shall be redeemed by the Company in each year commencing after a date to be
specified, at a redemption price per share to be specified, together with an
amount equal to all accrued and unpaid dividends thereon (which shall not, if
such Preferred Shares does not have a cumulative dividend, include any
accumulation in respect of unpaid dividends for prior dividend periods) to the
date of redemption. The redemption price may be payable in cash or other
property, as specified in the applicable Prospectus Supplement. If the
redemption price for Preferred Shares of any series is payable only from the net
proceeds of the issuance of capital stock of the Company, the terms of such
Preferred Shares may provide that, if no such capital stock shall have been
issued or to the extent the net proceeds from any issuance are insufficient to
pay in full the aggregate redemption price then due, such Preferred Shares shall
automatically and mandatorily be converted into shares of the applicable capital
stock of the Company pursuant to conversion provisions specified in the
applicable Prospectus Supplement.
 
                                       15
<PAGE>   46
 
     Notwithstanding the foregoing, unless (i) if such series of Preferred
Shares has a cumulative dividend, full cumulative dividends on all shares of any
series of Preferred Shares shall have been or contemporaneously are declared and
paid or declared and a sum sufficient for the payment thereof set apart for
payment for all past dividend periods and the then current dividend period and
(ii) if such series of Preferred Shares does not have a cumulative dividend,
full dividends on the Preferred Shares of any series have been or
contemporaneously are declared and paid or declared and a sum sufficient for the
payment thereof set apart for payment for the then current dividend period, no
shares of any series of Preferred Shares shall be redeemed unless all
outstanding Preferred Shares of such series are simultaneously redeemed;
provided however, that the foregoing shall not prevent the purchase or
acquisition of Preferred Shares of such series pursuant to a purchase or
exchange offer made on the same terms to holders of all outstanding Preferred
Shares of such series, and, unless (i) if such series of Preferred Shares has a
cumulative dividend, full cumulative dividends on all outstanding shares of any
series of Preferred Shares have been or contemporaneously are declared and paid
or declared and a sum sufficient for the payment thereof set apart for payment
for all past dividend periods and the then current dividend period and (ii) if
such series of Preferred Shares does not have a cumulative dividend, full
dividends on the Preferred Shares of any series have been or contemporaneously
are declared and paid or declared and a sum sufficient for the payment thereof
set apart for payment for the then current dividend period, the Company shall
not purchase or otherwise acquire directly or indirectly any Preferred Shares of
such series (except by conversion into or exchange for capital stock of the
Company ranking, junior to the Preferred Shares of such series as to dividends
and upon liquidation).
 
     If fewer than all of the outstanding Preferred Shares of any series are to
be redeemed, the number of shares to be redeemed will be determined by the
Company and such shares may be redeemed pro rata from the holders of record of
such shares in proportion to the number of such shares held by such holders
(with adjustments to avoid redemption of fractional shares) or by lot in manner
determined by the Company.
 
     Notice of redemption will be mailed at least 30 days but not more than 60
days before the redemption date to each holder of record of a Preferred Share of
any series to be redeemed at the address shown on the stock transfer books of
the Company. Each notice shall state: (i) the redemption date; (ii) the number
of shares and series of the Preferred Shares to be redeemed; (iii) the
redemption price; (iv) the place or places where certificates for such Preferred
Shares are to be surrendered for payment of the redemption price; (v) that
dividends on the shares to be redeemed will cease to accrue on such redemption
date; and (vi) the date upon which the holder's conversion rights, if any, as to
such shares shall terminate. If fewer than all the Preferred Shares of any
series are to be redeemed, the notice mailed to each such holder thereof shall
also specify the number of Preferred Shares to be redeemed from each such
holder. If notice of redemption of any Preferred Shares has been given and if
the funds necessary for such redemption have been set aside by the Company in
trust for the benefit of the holders of any of the Preferred Shares so called
for redemption, then from and after the redemption date dividends will cease to
accrue on such Preferred Shares, and all rights of the holders of such shares
will terminate, except the right to receive the redemption price.
 
LIQUIDATION PREFERENCE
 
     Upon any voluntary or involuntary liquidation, dissolution or winding up of
the affairs of the Company, then, before any distribution or payment shall be
made to the holders of any Common Shares or any other class or series of capital
stock of the Company ranking junior to the Preferred Shares in the distribution
of assets upon any liquidation, dissolution or winding up of the Company, the
holders of each series of Preferred Shares shall be entitled to receive out of
assets of the Company legally available for distribution to shareholders
liquidating distributions in the amount of the liquidation preference per share
(set forth in the applicable Prospectus Supplement), plus an amount equal to all
dividends accrued and unpaid thereon (which shall not include any accumulation
in respect of unpaid dividends for prior dividend periods if such Preferred
Shares do not have a cumulative dividend). After payment of the full amount of
the liquidating distributions to which they are entitled, the holders of
Preferred Shares will have no right or claim to any of the remaining assets of
the Company. In the event that upon any such voluntary or involuntary
liquidation, dissolution or winding up, the available assets of the Company are
insufficient to pay the amount of the liquidating distributions on all
outstanding Preferred Shares and the corresponding amounts payable on all shares
of other
 
                                       16
<PAGE>   47
 
classes or series of capital stock of the Company ranking on a parity with the
Preferred Shares in the distribution of assets, then the holders of the
Preferred Shares and all other such classes or series of capital stock shall
share ratably in any such distribution of assets in proportion to the full
liquidating distributions to which they would otherwise be respectively
entitled.
 
     If liquidating distributions shall have been made in full to all holders of
Preferred Shares, the remaining assets of the Company shall be distributed among
the holders of any other classes or series of capital stock ranking junior to
the Preferred Shares upon liquidation, dissolution or winding up, according to
their respective rights and preferences and in each case according to their
respective number of shares. For such purposes, the consolidation or merger of
the Company with or into any other trust or corporation, or the sale, lease or
conveyance of all or substantially all of the property or business of the
Company, shall not be deemed to constitute a liquidation, dissolution or winding
up of the Company.
 
VOTING RIGHTS
 
     Holders of the Preferred Shares will not have any voting rights, except as
set forth below or as otherwise from time to time required by law or as
indicated in the applicable Prospectus Supplement.
 
     Whenever dividends on any Preferred Shares shall be in arrears for six
consecutive quarterly periods, the holders of such Preferred Shares (voting
separately as a class with all other series of preferred shares upon which like
voting rights have been conferred and are exercisable) will be entitled to vote
for the election of two additional trustees of the Company at the next annual
meeting of shareholders and at each subsequent meeting until (i) if such series
of Preferred Shares has a cumulative dividend, all dividends accumulated on such
Preferred Shares for the past dividend periods and the then current dividend
period shall have been fully paid or declared and a sum sufficient for the
payment thereof set aside for payment or (ii) if such series of Preferred Shares
does not have a cumulative dividend, four consecutive quarterly dividends shall
have been fully paid or declared and a sum sufficient for the payment thereof
set aside for payment. In such case, the entire Board of Trustees of the Company
will be increased by two trustees.
 
     Unless provided otherwise for any series of Preferred Shares, so long as
any Preferred Shares remain outstanding, the Company shall not, without the
affirmative vote or consent of the holders of a majority of the shares of each
series of Preferred Shares outstanding at the time, given in person or by proxy,
either in writing or at a meeting (such series voting separately as a class),
(i) authorize or create, or increase the authorized or issued amount of, any
class or series of capital stock ranking prior to such series of Preferred
Shares with respect to payment of dividends or the distribution of assets upon
liquidation, dissolution or winding up, or reclassify any authorized capital
stock of the Company into any such shares, or create, authorize or issue any
obligation or security convertible into or evidencing the right to purchase any
such shares; or (ii) amend, alter or repeal the provisions of the Company's
Declaration of Trust or the certificate of designations for such series of
Preferred Shares, whether by merger, consolidation or otherwise, so as to
materially and adversely affect any right, preference, privilege or voting power
of such series of Preferred Shares or the holders thereof; provided, however,
that any increase in the number of the authorized preferred shares or the
creation or issuance of any other series of preferred shares, or any increase in
the amount of authorized shares of such series or any other series of Preferred
Shares, in each case ranking on a parity with or junior to the Preferred Shares
of such series with respect to payment of dividends or the distribution of
assets upon liquidation, dissolution or winding up, shall not be deemed to
materially and adversely affect such rights, preferences, privileges or voting
powers.
 
     The foregoing voting provisions will not apply if, at or prior to the time
when the act with respect to which such vote would otherwise be required shall
be effected, all outstanding shares of such series of Preferred Shares shall
have been redeemed or called for redemption and sufficient funds shall have been
deposited in trust to effect such redemption.
 
CONVERSION RIGHTS
 
     The terms and conditions, if any, upon which shares of any series of
Preferred Shares are convertible into Common Shares will be set forth in the
applicable Prospectus Supplement relating thereto. Such terms will
 
                                       17
<PAGE>   48
 
include the number of Common Shares into which the Preferred Share is
convertible, the conversion price (or manner of calculation thereof), the
conversion period, provisions as to whether conversion will be at the option of
the holders of the Preferred Shares or the Company, the events requiring an
adjustment of the conversion price and provisions affecting conversion in the
event of the redemption of such Preferred Shares.
 
LIMITATION OF LIABILITY; SHAREHOLDER LIABILITY
 
     Maryland law permits a REIT to provide, and the Declaration provides, that
no trustee, officer, shareholder, employee or agent of the Company shall be held
to any personal liability, jointly or severally, for any obligation of or claim
against the Company, and that, as far as practicable, each written agreement of
the Company is to contain a provision to that effect. Despite these facts
counsel has advised the Company that in some jurisdictions the possibility
exists that shareholders of a non-corporate entity such as the Company may be
held liable for acts or obligations of the Company. Counsel has advised the
Company that the State of Texas may not give effect to the limitation of
shareholder liability afforded by Maryland law, but that Texas law would likely
recognize contractual limitations of liability such as those discussed above.
The Company intends to conduct its business in a manner designed to minimize
potential shareholder liability by, among other things, inserting appropriate
provisions in written agreements of the Company; however, no assurance can be
given that shareholders can avoid liability in all instances in all
jurisdictions.
 
     The Declaration provides that, upon payment by a shareholder of any such
liability, the shareholder will be entitled to indemnification by the Company.
There can be no assurance that, at the time any such liability arises, there
will be assets of the Company sufficient to satisfy the Company's
indemnification obligation. The trustees intend to conduct the operations of the
Company, with the advice of counsel, in such a way as to minimize or avoid, as
far as practicable, the ultimate liability of the shareholders of the Company.
The trustees do not intend to provide insurance covering such risks to the
shareholders.
 
REDEMPTION AND BUSINESS COMBINATIONS
 
     For the Company to qualify as a REIT under the Code, in any taxable year,
not more than 50% in value of its outstanding Shares may be owned, directly or
indirectly, by five or fewer individuals during the last six months of such
year, and the Shares must be owned by 100 or more persons during at least 335
days of a taxable year or a proportionate part of a taxable year less than 12
months. In order to meet these and other requirements, the trustees have the
power to redeem or prohibit the transfer of a sufficient number of Shares to
maintain or bring the ownership of the Shares into conformity with such
requirements. In connection with the foregoing, if the trustees shall, at any
time and in good faith, be of the opinion that direct or indirect ownership of
Shares representing more than 8.5% in value of the total Shares outstanding (the
"Excess Shares") has or may become concentrated in the hands of one beneficial
owner, other than "Excepted Persons" (as defined in the Declaration), the
trustees shall have the power (i) to purchase from any shareholder of the
Company such Excess Shares, and (ii) to refuse to transfer or issue Shares to
any person whose acquisition of such Shares would, in the opinion of the
trustees, result in the direct or indirect beneficial ownership by any person of
Shares representing more than 8.5% in value of the outstanding Shares. Any
transfer of Shares, options, or other securities convertible into Shares that
would create a beneficial owner (other than any of the Excepted Persons) of
Shares representing more than 8.5% in value of the total shares outstanding
shall be deemed void ab initio and the intended transferee shall be deemed never
to have had an interest therein. Further, the Declaration provides that
transfers or purported acquisitions, directly, indirectly or by attribution, of
Shares, or securities convertible into Shares, that could result in
disqualification of the Company as a REIT are null and void and permits the
trustees to repurchase Shares or other securities to the extent necessary to
maintain the Company's status as a REIT. The purchase price for any Shares so
purchased shall be determined by the price of the Shares on the principal
exchange on which they are then traded, or, if no such price is available, then
the purchase price shall be equal to the net asset value of such Shares as
determined by the trustees in accordance with applicable law. From and after the
date fixed for purchase by the trustees, and so long as payment of the purchase
price for the Shares to be so redeemed shall have been made or duly provided
for, the holder of any Excess Shares so called for purchase shall cease to be
entitled to
 
                                       18
<PAGE>   49
 
distributions, voting rights and other benefits with respect to such Shares,
except the right to payment of the purchase price for the Shares.
 
     The Declaration also requires that "Business Combinations" (as defined
therein) between the Company and a beneficial holder of 10% or more of the
outstanding Shares be approved by the affirmative vote of the holders of at
least 75% of the Shares unless: (1) the Trustees by unanimous vote or written
consent shall have expressly approved in advance the acquisition of the
outstanding Shares that caused the Related Person (as defined in the
Declaration) to become a Related Person or shall have approved the Business
Combination prior to the Related Person involved in the Business Combination
having become a Related Person; or (2) the Business Combination is solely
between the Company and a 100% owned affiliate of the Company. As permitted by
law, the Company has elected to be governed by such provisions rather than the
provisions of Subtitle 6 of Title 3 of the Corporations and Associations Article
of the Annotated Code of Maryland regarding business combinations.
 
     Under the Declaration the number of trustees may be fixed from time to time
by two-thirds of the trustees or by amendment of the Declaration by the
shareholders of the Company, with a minimum of three and a maximum of 12
trustees, a majority of whom must be Independent Trustees. The Declaration fixes
the current number of trustees of the Company at five and divides the trustees
into three groups. Trustees in each group are elected to three-year terms. As
the trustees' terms expire, replacements are elected by a majority of the
outstanding Shares. The classified nature of the trustees may make it more
difficult for the shareholders to remove the management of the Company than if
all trustees were elected on an annual basis. Vacancies may be filled by a
majority of the remaining trustees, except that a vacancy among the Independent
Trustees must be filled by a majority of the remaining Independent Trustees or
by majority vote of the Company's shareholders. Any trustee may be removed for
cause by all the remaining trustees, or with or without cause by vote of
two-thirds of the Shares then outstanding and entitled to vote thereon.
 
     The provisions regarding business combinations and the classified nature of
the trustees and certain other matters may not be repealed or amended without
the affirmative vote of at least 75% of the shareholders of the Company,
provided that the trustees, by two-thirds vote, may, without the approval or
consent of the shareholders adopt any amendment that they in good faith
determine to be necessary to permit the Company to qualify as a REIT under the
Code.
 
     The foregoing provisions may have the effect of discouraging unilateral
tender offers or other takeover proposals which certain shareholders might deem
in their interests or pursuant to which they might receive a substantial premium
for their Shares. The provisions could also have the effect of insulating
current management against the possibility of removal and could, by possibly
reducing temporary fluctuations in market price caused by accumulations of
shares, deprive shareholders of opportunities to sell at a temporarily higher
market price. However, the Trustees believe that inclusion of the business
combination provisions in the Declaration may help assure fair treatment of
shareholders and preserve the assets of the Company.
 
CONTROL SHARE ACQUISITION
 
     Maryland law provides for a limitation of voting rights in a "control share
acquisition". The Maryland statute defines a "control share acquisition" at the
20%, 33 1/3% and 50% acquisition levels, and requires a two-thirds vote
(excluding shares owned by the acquiring person and certain members of
management) to accord voting rights to shares acquired in a control share
acquisition. The statute would require the target company to hold a special
meeting at the request of an actual or proposed control share acquiror subject
to compliance with certain conditions by such acquiror. In addition, unless the
charter, declaration of trust or By-Laws provide otherwise, the statute gives
the Company, within certain time limitations, various redemption rights if there
is a shareholder vote on the issue and the grant of voting rights is not
approved, or if an "acquiring person statement" is not delivered to the target
company within 10 days following a control share acquisition. Moreover, unless
the charter, declaration of trust or By-Laws provide otherwise, the statute
provides that if, before a control share acquisition occurs, voting rights for
"control shares" are approved at a shareholders meeting and the acquiror becomes
entitled to vote a majority of the shares entitled to vote, then all other
shareholders may exercise appraisal rights. The statute does not apply to shares
acquired in a merger,
 
                                       19
<PAGE>   50
 
consolidation or share exchange if the Company is a party to the transaction. An
acquisition of shares may be exempted from the control share statute provided
that a charter, declaration of trust or By-Law provision is adopted for such
purpose prior to the control share acquisition. There are no such provisions in
the Declaration or By-Laws of the Company.
 
                      DESCRIPTION OF COMMON SHARE WARRANTS
 
     The Company may issue Common Share Warrants for the purchase of Common
Shares. Common Share Warrants may be issued independently or together with any
other Offered Securities offered by any Prospectus Supplement and may be
attached to or separate from such Offered Securities. Each series of Common
Share Warrants will be issued under a separate warrant agreement (each, a
"Warrant Agreement") to be entered into between the Company and a warrant agent
specified in the applicable Prospectus Supplement (the "Warrant Agent"). The
Warrant Agent will act solely as an agent of the Company in connection with the
Common Share Warrants of such series and will not assume any obligation or
relationship of agency or trust for or with any holders or beneficial owners of
Common Share Warrants. The following sets forth certain general terms and
provisions of the Common Share Warrants offered hereby. Further terms of the
Common Share Warrants and the applicable Warrant Agreement will be set forth in
the applicable Prospectus Supplement.
 
     The applicable Prospectus Supplement will describe the terms of the Common
Share Warrants in respect of which this Prospectus is being delivered,
including, where applicable, the following:
 
      (1) the title of such Common Share Warrants;
 
      (2) the aggregate number of such Common Share Warrants;
 
      (3) the price or prices at which such Common Share Warrants will be
          issued;
 
      (4) the designation, number and terms of Common Shares purchasable upon
          exercise of such Common Share Warrants;
 
      (5) the designation and terms of the other Offered Securities with which
          such Common Share Warrants are issued and the number of such Common
          Share Warrants issued with each such Offered Security;
 
      (6) the date, if any, on and after which such Common Share Warrants and
          the related Common Shares will be separately transferable;
 
      (7) the price at which each Common Share purchasable upon exercise of such
          Common Share Warrants may be purchased;
 
      (8) the date on which the right to exercise such Common Share Warrants
          shall commence and the date on which such right shall expire;
 
      (9) the minimum or maximum amount of such Common Share Warrants which may
          be exercised at any one time;
 
     (10) information with respect to book-entry procedures, if any;
 
     (11) a discussion of certain federal income tax considerations; and
 
     (12) any other terms of such Common Share Warrants, including terms,
          procedures and limitations relating to the exchange and exercise of
          such Common Share Warrants.
 
                      RATIOS OF EARNINGS TO FIXED CHARGES
 
     The Company's ratio of earnings to fixed charges for the years ended
December 31, 1989, 1990, 1991, 1992 and 1993 and the quarter ended March 31,
1994 was 1.8x, 2.4x, 2.8x, 3.6x, 6.8x and 9.6x, respectively. To
 
                                       20
<PAGE>   51
 
date, the Company has not issued any preferred shares; therefore, the ratios of
earnings to combined fixed charges and preferred share dividends are unchanged
from the ratios presented in this section.
 
     For purposes of computing these ratios, earnings have been calculated by
adding fixed charges (excluding capitalized interest) to income (loss) before
income taxes and extraordinary items. Fixed charges consist of interest costs,
whether expensed or capitalized, the interest component of rental expense, and
amortization of debt discounts and issue costs, whether expensed or capitalized.
 
                              PLAN OF DISTRIBUTION
 
     The Company may sell the Offered Securities to one or more underwriters for
public offering and sale by them or may sell the Offered Securities to investors
directly or through agents. Any such underwriter or agent involved in the offer
and sale of the Offered Securities will be named in the applicable Prospectus
Supplement.
 
     Underwriters may offer and sell the Offered Securities at a fixed price or
prices, which may be changed, at prices related to the prevailing market prices
at the time of sale or at negotiated prices. The Company also may offer and sell
the Offered Securities in exchange for one or more of its then outstanding
issues of debt or convertible debt securities. The Company also may, from time
to time, authorize underwriters acting as the Company's agents to offer and sell
the Offered Securities upon the terms and conditions as are set forth in the
applicable Prospectus Supplement. In connection with the sale of Offered
Securities, underwriters may be deemed to have received compensation from the
Company in the form of underwriting discounts or commissions and may also
receive commissions from purchasers of Offered Securities for whom they may act
as agent. Underwriters may sell Offered Securities to or through dealers, and
such dealers may receive compensation in the form of discounts, commissions from
the underwriters and/or commissions from the purchasers for whom they may act as
agent.
 
     Any underwriting compensation paid by the Company to underwriters or agents
in connection with the offering of Offered Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers, are
set forth in the applicable Prospectus Supplement. Underwriters, dealers and
agents participating in the distribution of the Offered Securities may be deemed
to be underwriters, and any discounts and commissions received by them and any
profit realized by them on resale of the Offered Securities may be deemed to be
underwriting discounts and commissions, under the Securities Act of 1933.
Underwriters, dealers and agents may be entitled, under agreements entered into
with the Company, to indemnification against and contribution toward certain
civil liabilities, including liabilities under the Securities Act.
