Item 5.  Other Events.

A.  GPI Acquisition.

          As previously announced, on February 17, 1997 Health and Retirement
Properties Trust (the "Company" or "HRP") entered into a Agreement of Merger
(the "Merger Agreement") with Government Property Investors, Inc. (together
with its subsidiaries, except where the context requires otherwise, "GPI"), a
Delaware corporation, providing for the merger (the "Merger") of a wholly-owned
subsidiary of GPI into and with a wholly-owned subsidiary of the Company ("HRP
Merger Sub"). Except with respect to references to common shares of beneficial
interest of the Company ("Common Shares") and unless the context otherwise
requires, references in this Item of this Report to the Company include HRP 
Merger Sub and its subsidiaries. 

         Pursuant to the Merger and related transactions, the Company would
acquire up to 30 office buildings containing approximately 3.4 million square
feet, substantially all of which is leased to various agencies of the United
States Government (the "Government Office Properties"). Based upon the closing
sale price for the Common Shares as reported by the New York Stock Exchange (the
"Closing Price") on February 25, 1997 ($20.25 per share), the purchase price
would be approximately $448 million. The value of the First Closing
Consideration (as hereafter defined) will vary with the Common Share price on
the Closing Date (as hereafter defined). As set out in the Merger Agreement, the
purchase price payable on the Closing Date will be approximately $436 million,
of which approximately $72.6 million will be paid by the issuance of
approximately 4.2 million Common Shares, valued at $17.291 per share (the "First
Closing Consideration"), approximately $47 million will be paid by the Company's
assumption of debt secured by mortgages on four properties, and approximately
$317 million will be paid in cash at the time of or shortly after the
consummation of the Merger to retire other debt and pay certain obligations of
GPI and its subsidiaries assumed by the Company.

          The Company will pay an additional amount (the "Second Closing
Consideration") equal to the greater of $8 million or 3% of the aggregate cost
of Additional Properties (as hereafter defined) acquired by the Company prior 
to the first anniversary of the Closing Date (the "Second Closing Date") by 
the issuance of Common Shares valued at the arithmetic average of the closing 
sales prices for the Common Shares as reported by the NYSE for the 20 trading 
days immediately prior to the Second Closing Date.


         This transaction is expected to close, at least with respect to 24
Government Office Properties with a value of approximately $389 million
(calculated based upon the Closing Price on February 25, 1997), on or about
March 31, 1997 (the "Closing Date"). In addition, the Company will have the
option to pursue the acquisition of Additional Properties (as hereafter defined)
leased to various Government agencies where negotiations were commenced by the
sellers of the Government Office Properties.

          The information presented in this Report, unless otherwise indicated,
is stated as though the acquisition of all 30 of the Government Office
Properties has occurred. The closing under the Merger Agreement is subject to
certain conditions, including the delivery of certain estoppel certificates and
obtaining certain third-party consents. There can be no assurance, however, that
the acquisition of any or all of the Government Office Properties will be
completed, that the net operating income set forth herein will be achieved or
that, after the occurrence of the Merger, the Company will acquire all of the
properties under contract for acquisition or development or any additional
Government Office Properties.

         A copy of the Merger Agreement is filed as an exhibit to this Report.
The description of the Merger set forth herein describes certain provisions of 
the Merger Agreement, but does not purport to be complete and is subject to, 
and qualified in its entirety by reference to, all of the provisions of the 
Merger Agreement, including the definition of certain terms therein. 

<PAGE>

          The Merger. Pursuant to the Merger Agreement, Government Property 
Holdings Trust (together with its subsidiaries, except where context requires
otherwise, "GPH"), a Maryland real estate investment trust to be formed by GPI,
will merge with and into HRP Merger Sub and all outstanding stock of GPH will be
converted into the right to receive the First Closing Consideration and the
Second Closing Consideration. Prior to the Merger, GPI will contribute all of
its interest in certain of its subsidiaries to GPH, and GPH will assume certain
of GPI's indebtedness and certain other obligations of GPI. On the Closing Date,
pursuant to the Merger Agreement GPI, GPH, HRP, HRP Merger Sub and certain
related parties will enter into additional agreements (the "Other
Transactions"), among them the Investment and Registration Rights Agreement (the
"Registration Rights Agreement"), the Indemnification Agreement, the Voting
Agreement, Information Access Agreement and the Service Contract. See
"--Additional Agreements." The Merger is intended to qualify as a reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended.


          Government Office Properties. The Government Office Properties
consist of (i) 24 completed facilities purchased or developed by GPI prior to
the Merger (collectively, the "Existing Government Office Properties"); (ii)
three office buildings under development by GPI and third parties pursuant to
development agreements (the "Development Properties"); and (iii) three office
buildings with respect to which GPI has entered into purchase and sale
agreements as purchaser (the "Contract Properties"). Pursuant to the Merger
Agreement, if certain conditions relating to (i) the Development Property
located in Aurora, Colorado (the "Aurora Premises") are satisfied on or before
July 31, 1997, HRP will buy all interests of GPI and its affiliates in the
Aurora Premises and (ii) the Contract Properties are satisfied on or before the
Second Closing Date (hereafter defined), HRP will buy all interests of GPI and
its affiliates in the Contract Properties. In addition, GPI has entered into
negotiations to acquire an additional ten office buildings (the "Additional
Properties") which negotiations HRP may elect to continue following the Merger.
GPI has the option to transfer the Existing Government Office Property located
in Houston, Texas (the "Houston Premises") to a third party in return for a $5
million reduction in the purchase price. Based upon the Closing Price on
February 25, 1997, the reduction in the First Closing Consideration would be
$5.9 million.

          The Government Office Properties are located in 17 states and the
District of Columbia and are occupied by different agencies of the U.S.
Government, including the Internal Revenue Service, Drug Enforcement Agency,
Army Corps of Engineers and Department of Energy. GSA leases have been awarded
for the Development Properties, which are under development by GPI in
conjunction with third party developers and are scheduled to be completed by
January 1998. The Additional and Contract Properties are generally 100% leased,
primarily to the U.S. Government. See "Summary of the Government Office
Properties." The number of useable square feet of each Government Office
Property has been determined for these purposes based on the aggregate leased
square footage specified in currently effective leases.

          The average remaining lease term for the Government Office Properties
is approximately eight years. Most of these leases include tenant renewal
options for extended periods. The current rents payable under these leases are
approximately $61 million per year and most of the rental rates are subject to
annual adjustments based upon increasing operating expenses as measured by
Consumer Price Index increases. Generally, the leases are so called "modified
gross leases" under which the Company, as landlord, will be required to provide
certain property management services. The net operating income which the Company
will receive from these leases, before depreciation, amortization and interest
costs, and before management and home office costs, will depend upon the
efficiency with which the Company is able to provide these services, but the
Company estimates that such net income would be approximately $45 million per
annum. Five of the 30 Government Office Properties are currently under contract
for acquisition and/or development and will not produce rental income
until their acquisition and development is completed. 

          First Closing Consideration. The First Closing Consideration is 
payable by the issuance of Common Shares, valued at $17.291 per share, equal 
to $436 million minus the total debt of GPI and its subsidiaries (including
approximately $47 million of debt which will be assumed by HRP Merger Sub on the
Closing Date (the "Assumed Debt") but excluding debt to affiliates and certain
others), plus the aggregate amount of certain net current assets of GPH and its
subsidiaries as of the Closing Date.

          First Closing Consideration Adjustments. The amount of the First 
Closing Consideration is subject to the following reductions:

          i. an amount equal to the aggregate of prepayment penalties, if
             any, which would be incurred as the result of the prepayment of
             debt of GPI and its subsidiaries (exclusive of the Assumed Debt)
             on the Closing Date;

        ii. if the Development Property located in Golden, Colorado (the
            "Golden Premises") is not complete and the obligation of the tenant
            thereof to pay rent has not commenced by the Closing Date, the
            amount of $9,046,823;


                                       2

<PAGE>


       iii. if the Development Property located in San Diego, California (the
            "San Diego Premises") is not complete and the obligation of both of 
            the tenants thereof to pay rent has not commenced by the Closing 
            Date, the amount of $1,530,954;

        iv. $11,647,101, provided that GPH has not succeeded to the interest
            of GPI in the Aurora Premises;

         v. if the Contract Property located in Waco, Texas (the "Waco
            Premises") is not ready for acquisition on the Closing Date,
            the amount of $8,514,714;

       vi.  if the Contract Property located in Los Angeles, California (the
            "LA MEPS Premises") is not ready for acquisition on the
            Closing Date, the amount of $10,060,162;

      vii.  if the Contract Property located in Phoenix, Arizona (the "Phoenix
            Premises") is not ready for acquisition on the Closing Date,
            the amount of $12,159,106; and

     viii.  if GPI exercises its right to retain the Houston Premises, the
            amount of $5,000,000.

The Merger Agreement contemplates that GPH will not succeed to the interest of
GPI in the Aurora Premises on or before the Closing Date. 

          If GPI elects to retain the Houston Premises and sells the Houston 
Premises prior to the Closing Date and any of the proceeds of such sale (the
"Houston Proceeds") are included in the current assets of GPH used in the
calculation of the First Closing Consideration, the Common Shares issued on
account of the Houston Proceeds will be that number of Common Shares equal to
the quotient of the Houston Proceeds divided by $19.2125 per share.

          Upon completion of the development or acquisition of the Golden 
Premises, the San Diego Premises, the Aurora Premises, the Waco Premises, the LA
MEPS Premises and the Phoenix Premises, the amount of the reductions referred to
above, less amounts expended (or anticipated to be expended) by HRP Merger Sub
in connection with the acquisition or development of such premises (and in the
case of the Aurora Premises, see "--The Aurora Premises") will be payable by the
issuance of Common Shares valued at $17.291 per share.

          Second Closing Consideration. The aggregate cost of acquiring 
Additional Properties used to determine the Second Closing Consideration will
include the purchase price, any contingent purchase price, the amount of any
indebtedness assumed (but exclusive of transaction expenses and commissions paid
by HRP or any of its affiliates), and will include Additional Properties with
respect to which, prior to the Second Closing Date, HRP or any of its affiliates
have purchased or entered into a binding agreement to purchase. The Second
Closing Consideration payable in Common Shares will be adjusted (i) to offset
any difference between the debt and certain current assets of GPI used in the
determination of the First Closing Consideration as of the Closing Date and the
actual amounts of such debt and certain current assets following the Closing
Date; (ii) if the amounts paid to GPI or its successor pursuant to the Service
Contract (as hereafter defined) (the "Service Contract Payment") are less than
the amounts actually paid by GPI or its successor for office expenses, salaries
and other operating expenses through July 31, 1997, by the addition of an amount
of up to the difference between such amounts, provided that such amount shall
not exceed the difference between $947,935 and the Service Contract Payment;
(iii) if the aggregate amount funded or anticipated to be funded by HRP
subsequent to the consummation of the Merger to complete the Golden Premises
(including interest thereon) exceeds $9,046,823, by the deduction of one-half of
such excess; and (iv) if the aggregate amount funded or anticipated to be funded
by HRP subsequent to the consummation of the Merger to complete the San Diego
Premises (including interest thereon) exceeds $1,530,954, by the deduction of
one-half of such excess.

           Additional Agreements. Pursuant to the Merger Agreement, the
agreements described below (the "Additional Agreements") are to be entered into
by certain parties to the Merger Agreement and others. A copy of the form of
each Additional Agreement and each of certain other related agreements is filed
as a schedule to Exhibit 10.1 to this Report. The descriptions of the Additional
Agreements describe the material provisions of each of the Additional
Agreements, but do not purport to be complete and are subject to, and qualified
in their entirety by reference to, all of the provisions of each of the
Additional Agreements, including the definition of certain terms therein.

          Registration Rights Agreement. Pursuant to the Registration Rights
Agreement, HRP has agreed to file with the Securities and Exchange Commission 
within 30 days following the Closing Date a registration statement relating to
the offer and sale of Common Shares delivered on the Closing Date to GPI
pursuant to the Merger Agreement by the holders thereof. The Company has also
agreed to amend such registration statement from time to time to include
additional Common Shares delivered after the Closing Date to GPI and its
successors pursuant to the Merger Agreement. HRP is required to use its best
efforts to have such registration statement declared effective as soon as
reasonably practicable after filing and to maintain the continuous effectiveness
of such registration statement for three years from the Closing Date or such
shorter period as will terminate when all such Common Shares have been sold. The
Registration Rights Agreement provides for suspension periods when the
registration statement is not effective and for block out periods in connection
with other offerings of the securities of HRP, each on customary terms and
conditions. The Registration Rights Agreement also provides certain
cross-indemnities between HRP and sellers of the Common Shares subject to the
Registration Rights Agreement. Such indemnities may be unenforceable, in whole
or in part, under federal or state securities laws or certain public policies.


                                       3

<PAGE>

                   Indemnification Agreement. Pursuant to the Indemnification
Agreement, GPI will indemnify HRP and other related parties for certain losses
arising out of any breach of any warranty or representation made by GPI in the
Merger Agreement, the Registration Rights Agreement or the Indemnification
Agreement; provided that, any claim for indemnification must be made by 
December 31, 1997. The Indemnification Agreement provides that GPI has no
liability for such losses until such losses exceed $1,500,000 in the aggregate
(except for certain losses related to the Existing Government Office Property
located in College Park, Maryland) and that GPI shall have no liability for
losses in excess of the Second Closing Consideration.


                    Voting Agreement. At the time of the Merger, HRP Merger Sub
and The 1818 Fund II, L.P. and Rosecliff Realty, L.P., the principal
stockholders of GPI (the "Principal Stockholders"), will enter into the Voting
Agreement, pursuant to which each Principal Stockholder has agreed that it will
not, until the occurrence of a Change in Management (as defined in the Voting
Agreement) or until such Principal Stockholder, with its affiliates, owns less
than 25% of the aggregate Common Shares received by such Principal Stockholder
as Merger Consideration, unless otherwise approved by the Board of Trustees of
HRP, (i) transfer any Common Shares held by Principal Stockholder to any person
who, to the Principal Stockholders' knowledge, holds directly, or is an
affiliate of a person who holds, 5% or more of the aggregate Common Shares at
the time outstanding; (ii) make directly or indirectly or participate in an
unsolicited offer to purchase any Common Shares; (iii) vote (or direct to be
voted) any Common Shares or any other shares of equity interest in HRP as to
which either has direct or indirect voting power or control in favor of any
transaction that could result in a Change of Control (as defined in the Voting
Agreement) of HRP; or (iv) present any shareholder proposal dealing with a
Change of Control of HRP.

                   Information and Access Agreement. At the time of the Merger,
the Company and the Principal Stockholders will enter into the Information and
Access Agreement pursuant to which the Company will, upon request, permit the
Principal Stockholders to inspect the Company's properties, provide financial
information, make certain of the Company's officers available for consultation
and inform the Principal Stockholders of significant corporate actions. Each
Principal Stockholder has agreed to hold all such information in confidence. The
Information and Access Agreement will terminate on the third anniversary of the
Closing Date.

                   Service Contract. At the time of the Merger, GPI and M&P
Partners, Limited Partnership ("M&P"), an affiliate of HRPT Advisors, Inc.
("Advisors"), the Company's investment advisor, which is owned by Advisors and
Messrs. Gerard M. Martin and Barry M. Portnoy, the Managing Trustees of the
Company, will enter into the Service Contract, pursuant to which certain
employees of GPI will provide administrative and support services to HRP Merger
Sub until July 31, 1997. M&P is required to reimburse GPI for such employees'
compensation and for rent payments for GPI's office space in Washington, D.C.
until July 31, 1997 in an amount not to exceed $700,000.

                   The Aurora Premises. If, at any time on or before 
July 31, 1997, certain conditions relating to the Aurora Premises have been
satisfied, HRP will issue to GPI a number of Common Shares with an aggregate
value (with each such Common Share valued at $17.291) equal to $11,647,101 less
the sum of (x) $1,000,000, (y) the amount of any indebtedness or funding
obligations assumed by HRP with respect to the Aurora Premises, and (z) the cost
to complete construction of the Aurora Premises in accordance with the plans and
specifications therefor and as set forth in the guaranteed maximum price
construction contract relating to the Aurora Premises and including, without
limitation, any amounts required to be paid to buy out the third party
development partner and interest imputed on amounts advanced by HRP with respect
to the Aurora Premises, from the date advanced until the date the obligation to
pay rent of the tenant under the development lease in effect with respect to the
Aurora Premises shall commence, in consideration for the transfer of all GPI and
GPI affiliate ownership interests in the entity holding title to the Aurora
Premises. Within thirty (30) days after the last to occur of (x) completion of
the construction of the Aurora Premises, (y) the novation of the lease in effect
with respect to the Aurora Premises to HRP and (z) the commencement of the
obligation of the tenant under the lease to pay rent, HRP will issue GPI a
number of Common Shares valued at $17.291 per share with an aggregate value 
equal to the amount, if any, by which $11,647,101 exceeds the
actual aggregate amounts funded by HRP with respect to the Aurora Premises
(including, without limitation, interest and third party development partner
buy-out costs and Common Shares previously issued).

                                       4

<PAGE>

         Plan of Financing. Pursuant to the Merger Agreement, HRP will pay
certain debt and other obligations of GPI and its subsidiaries in the amount of 
approximately $317 million on the Closing Date. Funds to pay such debt and
other obligations may come from borrowings under HRP's unsecured bank credit
facility (the "Bank Credit Facility"), from new borrowings or from the sale of
Common Shares. The Bank Credit Facility is a $250 million unsecured revolving
credit facility with a syndicate of banks. This facility matures in 2000 and
interest on drawings is at LIBOR plus 87.5 basis points or prime. Aggregate
borrowings under the Bank Credit Facility at February 26, 1997 were $140
million. HRP is in the process of negotiating amendments to the Bank Credit
Facility to permit HRP to consummate the Merger and to extend the maturity 
until 2001.

         The Government Office Properties Business. Most of the Government
Office Properties are leased through the General Services Administration
("GSA"). HRP believes that the GSA's long term demand for leased space will
continue to be strong as a result of federal budget pressures to limit capital
expenditures and the need to use funds available for capital expenditures to
modernize the GSA inventory of owned buildings, over half of which exceed 50
years of age. Most large GSA leases are written for initial contractual terms of
10 to 20 years plus renewal options totaling an additional 5 to 20 years. Many
GSA leases, including leases for some Government Office Properties, permit the
GSA to terminate the lease by notices given any time after a so called "firm
term." The average remaining firm term for the Government Office Properties to
be acquired by HRP is approximately 8 years; the average remaining contractual
term for these properties is approximately 10 years; and the average remaining
full term for these leases, including all renewal options, is approximately 13
years.

         Based upon the GSA or tenant investments in improvements to the
Government Office Properties, the high cost of relocation, the stability of the
tenant missions and space requirements of the Government agencies which occupy
these properties, HRP believes that there is a high probability of lease
renewals for the Government Office Properties in many cases beyond the renewal
periods. Moreover, because of the locations of many of these properties and the
high standards to which they have been developed, HRP believes it may be able to
lease or sell most of such properties to commercial users in the event the GSA
terminates or fails to renew a lease.

         GSA is not directly dependent upon the government appropriations
process to fund its annual budget for contractual lease obligations. GSA has
authority to spend a lump sum amount from the Federal Buildings Fund for payment
of its lease obligations. The Federal Buildings Fund is primarily funded with
the lease payments of the government agency tenants, who pay GSA quarterly in
advance for the space they occupy. Although the budget of each GSA tenant agency
is subject to the appropriations process, virtually none of the agencies require
line item approval for lease payments under existing leases, and funds to meet
obligations under existing leases have been consistently available and have
continued to be available during government shut-downs. Each year Congress
allocates the percentage of the Federal Buildings Fund that GSA can spend for
leased space.

<PAGE>

         While the payment structure described in the preceding paragraph has
been in place since 1975 and GSA has historically had sufficient authority and
resources to meet its obligations under long-term leases, changes in the U.S.
Government's policies or regulations in this regard could have an adverse effect
on HRP. HRP's operation of the Government Office Properties could also be
adversely affected by changes in the procedures for authorizing GSA to enter
into new leases. HRP cannot predict what impact, if any, such initiatives will
have on HRP.

         Leases. The Government Office Properties are primarily leased to U.S.
Government agencies through GSA and, in three cases (the Government Office
Properties in Safford, Arizona, Gaithersburg, Maryland and Santa Fe, New
Mexico), directly to the tenant agency. While HRP believes the provisions of the
GSA leases on the Government Office Properties (the "Leases") as summarized
below are representative of the lease terms generally available from GSA, there
can be no assurance that such terms will be available with respect to other
properties acquired by HRP or to renewals by GSA of the Leases.
Although the Safford, Gaithersburg and Santa Fe leases do not have GSA as the 
lessee, such leases are on GSA lease forms; therefore, for purposes of
general description, the description of the Leases herein includes such leases.

          Each of the Leases requires GSA to pay (i) a fixed base rent amount
("Base Rent"), (ii) a pass-through for changes in real estate taxes from a base
year and (iii) annual CPI adjustments of the portion of the Base Rent that
represents estimated operating expenses and utilities. The Leases generally 
provide that GSA's obligation to pay rent is dependent on the lessor's
obligation to provide services, including all required building services,
utilities, maintenance and repairs. Therefore, if the lessor fails to provide
any such service, GSA has the right to offset the amount of any valid claim
against rent.

         Rental obligations under the Leases are absolute and unconditional
general obligations of the United States, subject to the terms of the particular
Lease. With one exception, the Leases do not contain any provisions conditioning
the payment of rent on annual appropriations. The U.S. Government's obligations
under leases such as the Leases are subject to the Prompt Payment Act and the
regulations promulgated thereunder by the Office of Management and Budget,
pursuant to which any rent payments not made when due will bear interest from
the day after the due date for not more than one year at an interest rate from
time to time established by the Secretary of the Treasury. Payment of the Base
Rent (including the CPI adjustment component of the Base Rent) is not
conditioned on monthly invoices or notices of adjustments, while invoices are
required for additional charges above the Base Rent. The Leases do not provide
for acceleration of the payment obligations thereunder for failure to make a
payment when due, but the Lessor would have standing to sue for collection of
unpaid rent under the Contract Disputes Act of 1978, as amended.

         The Leases generally have a fixed Base Term during which the lease is
not terminable or cancelable by either the U.S. Government tenant or the lessor.
In some cases, the lease may provide for a renewal option, in which case GSA
must take affirmative action to renew the lease. In other cases, the lease may
provide for early termination rights either after a specified date in the Base
Term or during a renewal period, in which case occupancy continues unless GSA
affirmatively acts to terminate the lease.

         The Leases can also be terminated at any time under the following
limited circumstances: (i) a substantial casualty or a taking by eminent domain
of a substantial portion of the leased property, (ii) upon default by the lessor
of its obligations under the lease, which default remains uncured after
applicable notice and cure period, or upon "repeated and unexcused" defaults
notwithstanding timely cure of such defaults, (iii) breach by the lessor of
various representations, including those regarding PCB's, asbestos or other
hazardous waste or (iv) violation by the lessor of statutes relating to, among
other things, kick-backs, equal opportunity or use of small business concerns
and small disadvantaged business concerns. Any provider of goods and
services to the U.S. Government, including a landlord under a lease, may be
debarred, suspended or otherwise declared ineligible for the award of contracts
by any federal agency if such provider is determined to have, among other
things, committed fraud or a criminal offense in obtaining or performing public
contracts, violated federal or state anti-kickback or similar statutes or
repeatedly defaulted under public contracts. In addition, GSA has the right to
terminate a lease in the event of a violation by the landlord of certain
regulations such as those requiring equal opportunity hiring 


                                       6

or the use of subcontractors that qualify as small businesses or minority-owned
businesses. Any such violation or repeated defaults by HRP or any of its
officers could (i) disqualify HRP from acquiring additional government-leased
properties or obtaining renewals of the Leases or (ii) result in termination of
the Leases, all of which would have an adverse effect on HRP's Funds from
Operations and its ability to make expected distributions to shareholders. HRP
will generally be compensated by insurance proceeds in the case of insured
casualties or a condemnation award in the case of a taking by eminent domain.
HRP believes that the probability of renewal for GSA leases is high, primarily
because of the tenant's investment in the leased facilities and, with respect to
the Government Office Properties, the stability of the tenant's mission and
resulting space requirements. 


          While at the closing of the Merger HRP (i) anticipates receiving 
certificates from GSA to the effect that GSA has given no notice of existing
defaults by GPI under any of the leases of the Existing Government Office
Properties and (ii) will be provided a limited indemnity for liabilities HRP
incurs that relate to prior periods, there can be no assurance that such
certificates and indemnities would be sufficient to protect HRP from such
liabilities.

(1)  The Kansas City property is occupied by six federal government agencies 
     under four separate leases: Housing and Urban Development, Bureau of 
     Census, Bureau of Prisons, Department of Labor, Equal Employment 
     Opportunity Commission and Civil Rights Commission. A portion of the space 
     is leased to commercial tenants and the State of Kansas.

(2)  The Washington, D.C. (Indiana Ave.) property is occupied by four agencies
     under separate leases: the Defense Nuclear Facilities Safety Board; the 
     Veteran's Administration General Counsel; the U.S. Court of Veteran's 
     Appeals; and the Department of Justice Child Care Center. A portion of the
     space is leased to commercial retail tenants. 

(3)  The Buffalo, NY property is leased under three separate GSA leases to
     different agencies within the Department of Justice: the U.S. Attorney's
     Office; the Immigration and Immigration and Naturalization Service and the
     Executive Office of Immigration Review. 


                                       9

(4)  This Property is under an active lease and lease payments are being made,
     but the tenant is not occupying this building. 

(5)  Occupancy to begin upon completion of development. 


(6)  There are two government agency leases for this property. The primary
     tenant has begun occupancy. The secondary tenant's occupancy will begin
     when certain buildouts have been completed.


         GSA's standards for office facilities are comparable to Class A
commercial facilities, and the improvements in many of the Government Offices
have security features, energy conservation systems and technological capacity
that are higher than in most commercial facilities and amenities not normally
included in standard commercial space, such as child care centers, fitness
centers and cafeterias. In addition, GSA requires its leased premises to comply
with strict building safety standards, including handicap accessibility, testing
for radon, lead in paint or water and air quality.

         HRP will carry, upon taking title to the Government Office Properties,
comprehensive liability, fire, extended coverage, rental loss and title
insurance covering all of the Government Office Properties, with policy
specifications, insured limits and deductibles customarily carried for similar
properties with carriers management deems capable to providing such coverage.
However, certain losses may not be insurable or may be insurable only at
prohibitive rates. In the event of a partial casualty or condemnation of a
Government Office Property, GSA is entitled to a rent abatement for the
untenantable portion of the Government Office Property, and HRP's coverage will
include rental loss for all periods during which GSA is entitled to an abatement
under the Leases. The Government Office Properties are insured for loss due to
terrorist activities, although there can be no assurance that insurance for
such risks will continue to be available at acceptable rates. Should an
uninsured loss or a loss in excess of insured limits occur, HRP could lose its
capital invested in the affected property, as well as the anticipated future
revenues from such property and would continue to be obligated on any mortgage
indebtedness or other obligations related to the property. Any such loss could
materially and adversely affect the business and financial condition of HRP. HRP
believes that the Government Office Properties will be adequately insured in
accordance with industry standards.

         In connection with each Property, a Phase I environmental site 
assessment was performed by an independent engineering firm. The studies were
performed at various times between 1993 and 1996 and in connection with the
Merger, HRP has contracted for updates to such Phase I studies. These Phase I
studies have included, among other things, a visual inspection of the Properties
and the surrounding area and a review of relevant state, federal and historical
documents. In certain instances, the consultant performed limited sampling for
the presence of radon, lead paint, and asbestos containing materials. In several
cases surface sampling was undertaken either as part of the Phase I study, as a
subsequent Phase II investigation or by others prior to GPI's acquisition of the
property.


         Based on the Phase I and other environmental studies, HRP does not 
believe that there are any environmental liabilities associated with any of the
Government Office Properties that would have a material adverse effect on HRP's
business, assets or results of operations taken as a whole, nor is HRP aware of
any such material environmental liability. Nevertheless, it is possible that the
Phase I and other environmental studies did not reveal all environmental
liabilities or that there are material environmental liabilities of which HRP is
unaware.

         In addition, there can be no assurance that (i) future laws,
ordinances regulations, or court decisions will not impose any material
environmental liability or (ii) the current environmental conditions of the
Government Office Properties will not be affected by tenants, by the condition
of land or operations in the vicinities of the properties (such as the presence
or operation of underground storage tanks), or by third parties unrelated to
HRP.

B.  Authorization of Additional Common Shares of Beneficial Interest.

         In connection with the Merger described above under "GPI Acquisition"
and the contemplated financing thereof, the Trustees of the Company have voted
to increase the authorized number of common shares of beneficial interest,
$0.01 par value per share, of the Company from 100,000,000 to 125,000,000. As
provided in the Company's Amended and Restated Declaration of Trust, as amended,
such increase does not require the consent or approval of shareholders of the
Company.

Management's Discussion and Analysis of Financial Condition
and Results of Operations

Results of Operations
- ---------------------

Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

     Total revenues for the year ended December 31, 1996 were $120.2 million, an
increase of $6.9 million over the year ended December 31, 1995. Rental income
increased to $98.0 million from $90.2 million and interest and other income
decreased to $22.1 million from $23.1 million. Rental income increased as a net
result of new real estate investments during 1996, offset by the exclusion of
rental revenue from the Company's formerly wholly owned subsidiary Hospitality
Properties Trust ("HPT"). HPT is a real estate investment trust investing
principally in income producing hotel real estate. The Company's investment in
HPT is accounted for using the equity method, and the 1996 period does not
include revenue and expenses of HPT. Interest and other income decreased as a
[net result of the scheduled and early repayment of mortgage loans acquired from
the Resolution Trust Company in 1992 and 1993. The Company anticipates that such
prepayments will continue and consequently interest income will decline in the
future. This interest income decline was partially offset in 1996 by short term
investment income on excess cash which resulted from the Company's issuance of
convertible debentures during the fourth quarter of 1996.

     Total expenses for 1996 increased to $55.5 million from $54.7 million in
1995. The increase of $0.8 million is the net result of higher operating,
general and administrative expenses during the 1996 period. Interest expense
declined due to lower borrowings and lower interest rates during 1996 as
compared to 1995. Depreciation expense was essentially unchanged as the net
result of new real estate investments during 1996 was offset by the HPT
transaction described above. Amortization expense declined due to the write-off
of deferred finance fees in March 1996 and October 1996.

     Income before gain (loss) on sale of properties and extraordinary items for
1996 increased to $77.2 million, or $1.16 per share, from $61.8 million, or
$1.04 per share, in 1995. Net income for 1996 increased to $73.3 million, or
$1.11 per share, from $64.2 million, or $1.08 per share, in 1995. These
increases are primarily the result of net new real estate investments and the
recognition of the gain on the equity transaction of HPT.

     The Company's business goal is to maximize funds from operations ("FFO")
rather than net income. The Company's Board of Trustees considers FFO, among
other factors, when determining dividends to be paid to shareholders. The
Company has adopted the National Association of Real Estate Investment Trust's
("NAREIT") definition of FFO as income before equity in earnings of HPT, gain
(loss) on sale of real estate and extraordinary items, plus depreciation, other
non-cash items and the Company's proportionate share of HPT's FFO. Funds from
operations for the year ended December 31, 1996, was $99.1 million, or $1.50 per
share, versus $84.6 million, or $1.43 per share, in 1995. Funds from operations
for 1996 increased $14.5 million, or 17.1%, over the prior year. The increase is
the result of new investments in 1996. Dividends declared for the years ended
December 31, 1996 and 1995 were $94.3 million, or $1.42 per share, and $83.9
million, or $1.38 per share, respectively. Dividends in excess of net income
constitute a return of capital. For 1996, the return of capital portion reported
was 24.8% of dividends. Cash flow provided by operating activities and cash
available for distribution may not necessarily equal funds from operations as
the cash flow of the Company is affected by other factors not included in the
funds from operations calculation, such as changes in assets and liabilities.

     Cash flow provided by (used for) operating, investing and financing
activities were $98.3 million, ($235.3 million) and $140.2 million, respectively
for the year ended December 31, 1996 and $82.3 million, ($190.3 million) and
$68.8 million, respectively, for the year ended December 31, 1995.

Year Ended December 31, 1995 Compared to Year Ended December 31, 1994

     Total revenues for the year ended December 31, 1995 were $113.3 million, an
increase of $26.6 million, or 30.7%, over the year ended December 31, 1994.
Rental income increased to $90.2 million from $63.9 million and interest income
increased to $23.1 million from $22.8 million. Rental income increased as a
result of new purchase and lease investments during 1995 and a full year's
results on 1994 investments. Interest income increased slightly due to interest
income from new investments in mortgages and notes, offset by the reduction in
interest income resulting from the repayment of existing mortgages and notes.

Management's Discussion and Analysis of Financial Condition
and Results of Operations



     Total expenses for 1995 increased to $54.7 million from $28.8 million for
the comparable 1994 period. The increase of $25.9 million was due primarily to
increases in interest expense of $15.3 million, general and administrative
expense of $1.8 million, and depreciation and amortization expense of $8.1
million. The increases in general and administrative and depreciation and
amortization expenses are directly related to the Company's increased real
estate investments whereas interest expense increased primarily due to higher
amounts outstanding under the revolving credit facility and the issuance of $200
million senior notes issued in July 1994.

     Income before gain (loss) on sale of properties and extraordinary items for
1995 increased to $61.8 million, or $1.04 per share, from $57.9 million, or
$1.10 per share, in 1994. Per share amounts decreased reflecting the issuance of
9 million new shares of the Company's stock in December 1994 and 6.5 million new
shares issued in December 1995.

     Net income in 1995 and 1994 was $64.2 million, or $1.08 per share, and
$49.9 million, or $.95 per share, respectively. Funds from operations for the
year ended December 31, 1995 was $84.6 million, or $1.43 per share, versus $71.9
million, or $1.36 per share, in 1994. FFO for 1995 increased $12.7 million, or
17.7%, over the prior year. The increase is the result of new investments in
1995. Dividends declared for the years ended December 31, 1995 and 1994 were
$1.38 and $1.33 per share, respectively. Dividends in excess of net income
constitute a return of capital. For 1995 the return of capital portion was 11.8%
of dividends and 5.9% of dividends was considered a long term capital gain.

     Cash flow provided by (used for) operating, investing and financing
activities were $82.3 million, ($190.3 million) and $68.8 million, respectively,
for the year ended December 31, 1995 and $76.4 million, ($261.8 million) and
$229.4 million, respectively in 1994.

Liquidity and Capital Resources

     Total assets of the Company increased to $1.2 billion at December 31, 1996
from $999.7 million as of December 31, 1995. The increase of $229.8 million, or
23.0%, is primarily the result of increases in the Company's net new real estate
investments.

     During 1996, the Company acquired five nursing properties, three retirement
communities, twelve medical office buildings and invested in capitalized
improvements for existing properties for an aggregated amount of approximately
$225.4 million. In addition, the Company provided debt and improvement financing
totaling $17.2 million secured by a retirement community and by properties under
existing mortgages with the Company. These transactions were funded by borrowing
on the Company's revolving credit facility and available cash. In addition, the
Company received principal payments and repayments on real estate mortgages of
$10.2 million.

     At December 31, 1996, the Company owned 4,000,000, or 14.9%, of the common
shares of beneficial interest of HPT with a carrying value of $103.1 million and
market value of $116.0 million. During April 1996, HPT completed a public stock
offering of 14,250,000 common shares of beneficial interest at a per share price
of $26.625 for total consideration of approximately $379.4 million. As a result
of this transaction, the Company's ownership percentage in HPT was reduced from
31.8% to 14.9% and the Company realized a gain of $3.6 million. Although the
Company did not sell any shares, pursuant to the Company's accounting policy,
gains and losses on the issuance of common shares of beneficial interest by HPT
are recognized in the Company's income statement.

     In January 1996, the Company issued 475,000 common shares resulting in net
proceeds of approximately $7 million as a result of the underwriters' exercise
of the over-allotment option granted pursuant to the Company's equity offering
in December 1995.

     In March 1996, the Company entered into a new credit facility to refinance
its $250 million unsecured revolving bank credit facility. The restated credit
facility matures in 2000 and bears interest at LIBOR plus 0.875% per annum. In
connection with the refinancing, the Company recognized an extraordinary loss of
$2.4 million from the early write-off of capitalized expenses associated with
the prior credit facility.

Management's Discussion and Analysis of Financial Condition
and Results of Operations




     In April, 1996 the Company prepaid the outstanding secured Revenue
Refunding Bonds totaling $17.6 million by borrowing on the revolving bank credit
facility and from available cash.

     In October 1996, the Company issued $200 million of 7.5% and $40 million of
7.25% Convertible Subordinated Debentures (the "Debentures") due 2003 and 2001,
respectively. The Debentures are non-callable for three years but are
convertible at any time prior to maturity into common shares of the Company at a
price of $18 per share. The net proceeds were used in part to repay the then
outstanding balance of $147 million on the Company's revolving bank credit
facility and $75.5 million was placed in an irrevocable trust to complete an
in-substance defeasance of the $75 million Floating Rate Senior Notes, Series A,
due 1999. The Company recognized an extraordinary loss of $1.5 million as a
result of the write-off of capitalized expenses associated with the debt prepaid
in the fourth quarter of 1996. At December 31, 1996, approximately $12.2 million
of the Debentures due 2003 had been converted into 679,441 common shares of the
Company. During January 1997, approximately $16 million of the Debentures due
2003 had been converted into 891,496 common shares of the Company.

     At December 31, 1996, the Company had $21.9 million of cash and cash
equivalents and had drawn $140 million of the $250 million revolving debt
facility. In addition, in June 1996 the Company filed a $750 million shelf
registration statement ("Shelf") that was declared effective by the Securities
and Exchange Commission. At December 31, 1996, $640 million was available to be
drawn on the Shelf.

     As of December 31, 1996, the Company had commitments to provide improvement
financing to existing properties and to purchase a medical office building
totaling approximately $16 million. In January 1997, the Company acquired the
medical office building for $5.4 million with available cash. In February 1997,
the Company announced it had entered into an agreement to acquire up to 30
office buildings which are leased to various agencies of the United States
government. The properties comprise approximately 3.4 million square feet and
are located in 17 states and the District of Columbia. Under the terms of the
acquisition agreement, consideration to be paid for this acquisition is
approximately $317 million in cash to retire certain assumed debt and to pay
certain other obligations of the seller, plus the assumption of approximately
$47 million of other debt and the issuance of approximately 4.2 million
unregistered common shares of the Company. The acquisition is subject to various
conditions customary in real estate transactions and is expected to be
substantially consummated by March 31, 1997; however, no assurances can be given
that this transaction will actually close.

     The Company intends to fund these commitments with a combination of cash on
hand, amounts available under its existing credit facilities, proceeds of
mortgage prepayments, if any, and/or proceeds of other financings such as the
possible issuance of additional securities.

     The Company continues to seek new investments to expand and diversify its
portfolio of leased and mortgaged health care, retirement and related real
estate. The Company believes that the transactions described above will improve
the security of its future funds from operations, cash available for
distribution, and dividends. The Company intends to balance the use of debt and
equity in such a manner that the long term cost of funds borrowed to acquire or
mortgage finance facilities is appropriately matched, to the extent practicable,
with the terms of the investments made with such borrowed funds. As of December
31, 1996, the Company's debt as a percentage of total book capitalization was
approximately 41%. There can be no assurances that debt or equity financing will
be available to fund the Company's existing commitments or its future growth,
but the Company expects such financing will be available.


Impact of Inflation
- -------------------

     Management believes that the Company is not adversely affected by
inflation. In the real estate market, inflation tends to increase the value of
the Company's underlying real estate which may be realized at the end of the
lessees' fixed rent terms. In the health care and hotel industries, inflation
usually increases the lessees' and mortgagors' revenues, thereby increasing the
Company's additional rent or interest. At December 31, 1996, increases in
interest rates on $200 million of the Company's outstanding debt were capped by
the use of interest rate cap agreements which provide for maximum weighted
average interest rates of approximately 6.24% on its variable rate debt.

Management's Discussion and Analysis of Financial Condition
and Results of Operations

Certain Considerations
- ----------------------

         The discussion and analysis of the Company's financial condition and
results of operations requires the Company to make certain estimates and
assumptions and contains certain statements of the Company's beliefs, intent or
expectation concerning projections, plans, future events and performance. The
estimates, assumptions and statements, such as those relating to the Company's
ability to expand its portfolio, performance of its assets, the ability to pay
dividends from FFO, its tax status as a "real estate investment trust," the
ability to appropriately balance the use of debt and equity and to access
capital markets depends upon various factors over which the Company and/or the
Company's lessees and mortgagors have or may have limited or no control. Those
factors include, without limitation, the status of the economy, capital markets
(including prevailing interest rates), compliance with and changes to
regulations within the health care industry, competition, changes to federal,
state and local legislation and other factors. The Company cannot predict the
impact of these factors, if any. However, these factors could cause the
Company's actual results for subsequent periods to be different from those
stated, estimated or assumed in this discussion and analysis of the Company's
financial condition and results of operations. The Company believes that its
estimates and assumptions are reasonable and prudent at this time.

REPORT OF INDEPENDENT AUDITORS


To the Trustees and Shareholders
Health and Retirement Properties Trust

We have audited the accompanying consolidated balance sheets of Health and
Retirement Properties Trust as of December 31, 1996 and 1995, and the related
consolidated statements of income, shareholders' equity, and cash flows for each
of the three years in the period ended December 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits. The financial statements of Hospitality Properties Trust (a real
estate investment trust in which the Company has a 14.9% interest) have been
audited by other auditors whose report has been furnished to us; insofar as our
opinion on the consolidated financial statements relates to data included for
Hospitality Properties Trust, it is based solely on their report.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits and the report of other auditors provide a reasonable
basis for our opinion.

In our opinion, based on our audits and the report of other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of Health and Retirement Properties
Trust at December 31, 1996 and 1995, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Trustees and Shareholders of
Hospitality Properties Trust:

We have audited the consolidated balance sheets of Hospitality Properties Trust
(the "Company") as of December 31, 1995 and 1996, and the related consolidated
statements of income, shareholders' equity and cash flows for the period from
February 7, 1995 (inception) to December 31, 1995 and the year ended 
December 31, 1996 not presented separately herein. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Hospitality
Properties Trust as of December 31, 1995 and 1996, and the results of its
operations and its cash flows for the period from February 7, 1995 (inception)

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (Dollars in thousands, except per share amounts)

Note 1.  Organization

    Health and Retirement Properties Trust, a Maryland real estate investment
trust (the "Company"), was organized on October 9, 1986. The Company invests in
income-producing real estate, primarily retirement housing and health care
related properties. As of December 31, 1996, the Company had investments in 175
properties located in 28 states and the District of Columbia. The properties
include 122 long-term care facilities, 25 retirement and assisted living
communities, 12 nursing homes with subacute services and 16 medical office
buildings and clinics. In addition, at December 31, 1996, the Company had a
14.9% equity investment in Hospitality Properties Trust ("HPT"). At December 31,
1996, HPT owned 82 hotels in 26 states.

    The Company is dependent upon its lessees' and mortgagors' compliance with
regulations within the health care industry. Future changes to these regulations
may affect the health care industry, the Company's lessees and mortgagors and,
as a result, the Company.


Note 2.  Summary of Significant Accounting Policies

    Basis of Presentation. The consolidated financial statements include the
Company's investment in 100% owned subsidiaries. The Company's investment in 50%
or less owned companies is accounted for using the equity method. All
inter-company transactions have been eliminated. The Company uses the income
statement method to account for issuance of common shares of beneficial interest
by HPT. Under this method, gains and losses on issuance of stock by HPT are
recognized in the Company's income statement.

    Real Estate Property and Mortgage Investments. Real estate properties and
mortgages are recorded at cost. Depreciation on real estate investments is
provided for on a straight-line basis over the estimated useful lives ranging up
to 40 years. Impairment losses on investments are recognized where indicators of
impairment are present and the undiscounted cash flow (net realizable value)
estimated to be generated by the Company's investments are less than the
carrying amount of such investments. The determination of net realizable value
includes consideration of many factors including income to be earned from the
investment, holding costs (exclusive of interest), estimated selling prices, and
prevailing economic conditions.

    Cash and Cash Equivalents. Cash, over-night repurchase agreements and
short-term investments with maturities of three months or less at the date of
purchase are carried at cost plus accrued interest.

    Deferred Interest and Finance Costs. Costs incurred to secure certain
borrowings are capitalized and amortized over the terms of the respective loans.
Accumulated amortization at December 31, 1996 and December 31, 1995 was $1,171
and $2,853 respectively.

    Interest Rate Hedging Arrangements. The Company enters into interest rate
hedging arrangements to limit its exposure to increasing interest rates with
respect to its bank borrowings and notes payable. Their cost is included in
interest expense ratably over the terms of the respective agreements. Amounts
receivable from hedging arrangements are accrued as an adjustment to interest
expense. The unamortized cost of these agreements is included in other assets.

    Revenue Recognition. Rental income from operating leases is recognized on a
straight line basis over the life of the lease agreements. Interest income is
recognized as earned over the terms of the real estate mortgages. Additional
rent and interest revenue is recognized as earned.

    Income Per Share. Income per share is computed using the weighted average
number of shares outstanding during the period. The effect of the convertible
debentures on fully diluted earnings per share is anti-dilutive. Supplemental
income per share for the years ended December 31, 1995, and 1994 was $1.11 and
$.93, respectively, based on the assumption that the issuance of shares in the
Company's public offerings during 1995 and 1994, and the related repayment of
outstanding bank borrowings, took place at the beginning of each year.

    Reclassifications. Certain reclassifications have been made to the prior
years' financial statements to conform with the current year's presentation.

    Federal Income Taxes. The Company is a real estate investment trust under
the Internal Revenue Code of 1986, as amended. Accordingly, the Company expects
not to be subject to federal income taxes provided it distributes its taxable
income and meets certain other requirements for qualifying as a real estate
investment trust.

    Use of Estimates. Preparation of these financial statements in conformity
with generally accepted accounting principles requires management to make
certain estimates and assumptions that may affect the amounts reported in these
financial statements and related notes. The actual results could differ from
these estimates.

Note 3.  Real Estate Properties

    During the year ended December 31, 1996, the Company acquired five nursing
properties, three retirement communities and twelve medical office buildings for
an aggregated amount of approximately of $213,911 in nine separate transactions.
In addition, the Company provided improvement financing at existing properties
of approximately $11,517. The medical office buildings are managed by M&P
Partners Limited Partnership ("M&P"), an affiliate of the Company. In January
1997, the Company acquired a medical office building for $5,375; this building
is also managed by M&P.

    The Company's real estate properties are leased pursuant to noncancellable,
fixed term operating leases expiring from 1997 to 2021. Generally, the Company's
leases to a single tenant are cross-collateralized, cross-defaulted and
cross-guaranteed. The leases generally provide for renewal terms at existing
rates followed by several market rate renewal terms. The majority of the leases
are triple net leases and generally require the lessee to pay minimum rent,
additional rent based upon increases in net patient revenues, real estate taxes,
and all operating costs associated with the leased property. Additional rent and
interest for the years ended December 31, 1996, 1995 and 1994 were $3,222,
$3,768 and $2,768, respectively.

    The future minimum lease payments to be received by the Company during the
current terms of the leases as of December 31, 1996, are approximately $108,965
in 1997, $107,934 in 1998, $102,612 in 1999, $101,306 in 2000, $98,403 in 2001
and $871,523 thereafter.


Note 4.  Investment in Hospitality Properties Trust

    At December 31, 1996, the Company owned 4,000,000 common shares of
beneficial interest of HPT with a carrying value of $103,062 and market value of
$116,000. HPT is a real estate investment trust investing principally in income
producing hotel real estate. The Company's percentage of ownership of HPT as of
December 31, 1996, was 14.9%. The Company's investment in HPT has been accounted
for using the equity method. During April 1996, HPT completed a public stock
offering of 14,250,000 common shares of beneficial interest at a per share price
of $26.625 for total consideration of approximately $379,406. As a result of
this transaction, the Company's ownership percentage in HPT was reduced from
31.7% to 14.9% and the Company realized a gain of $3,603. Although the Company
did not sell any shares, pursuant to the Company's accounting policy, gains and
losses on the issuance of common shares of beneficial interest by HPT are
recognized in the Company's income statement.

    Summarized financial data of HPT is as follows:

Note 8.  Transactions with Affiliates

    The Company has an agreement with the Advisor whereby the Advisor provides
investment, management and administrative services to the Company. The Advisor
is owned by Gerard M. Martin and Barry M. Portnoy, who also serve as Managing
Trustees of the Company. Messrs. Martin and Portnoy are principal shareholders
of Connecticut Subacute Corporation ("CSC"), Connecticut Subacute Corporation
II, New Hampshire Subacute Corporation and Vermont Subacute Corporation
(collectively the "Subacute Entities") and were formerly directors of
Horizon/CMS Healthcare Corporation ("Horizon") and Greenery Rehabilitation
Group, Inc. ("Greenery"), which merged with Horizon in 1994. Horizon and the
Subacute Entities are lessees of the Company. The Company has extended a $4,000
line of credit to CSC until June 30, 1997. At December 31, 1996, there was
$2,365 outstanding under this agreement. The lease and mortgage transactions
with the Subacute Entities and Horizon are based on market terms and are
generally similar to the Company's lease and mortgage agreements with
unaffiliated companies. The former president of the Company is the president of
the Subacute Entities. Mr. Portnoy is a partner in the law firm which provides
legal services to the Company. The Advisor is the general partner of M&P, which
provides management services for some of the Company's recently acquired medical
office buildings. The property management fees paid to M&P are generally equal
to three percent of gross rents from the managed properties.

    The Advisor is compensated at an annual rate equal to .7% of the Company's
real estate investments up to $250 million and .5% of such investments
thereafter. The Advisor is entitled to an incentive fee comprised of restricted
shares of the Company's common stock based on a formula. Incentive fees for the
years ended December 31, 1996, 1995 and 1994 were $610, $580 and $239, which
represent approximately 32,846, 35,560 and 17,400 common shares respectively. At
December 31, 1996, the Advisor owned 1,049,210 common shares.

    Amounts resulting from transactions with affiliates included in the

                         Report of Independent Auditors


Board of Directors and Stockholders
Government Property Investors, Inc.

We have audited the accompanying consolidated balance sheets of Government
Property Investors, Inc., (the "Company") as of December 31, 1996 and 1995 and
the related consolidated statements of operations, stockholders'
equity/(deficit), and cash flows for the years ended December 31, 1996 and 1995,
and the combined statements of operations, owners' equity, and cash flows of
GovProp Entities for the period from May 20, 1994 (inception) to December 31,
1994. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
Government Property Investors, Inc. at December 31, 1996 and 1995 and the
consolidated results of their operations and their cash flows for the years
ended December 31, 1996 and 1995, and the combined financial statements referred
to above present fairly, in all material respects, the combined results of
operations and cash flows of GovProp Entities for the period from May 20, 1994
(inception) to December 31, 1994, in conformity with generally accepted
accounting principles.

The accompanying financial statements have been prepared assuming that
Government Property Investors, Inc. will continue as a going concern. As more
fully described in Note 1, the Company has incurred recurring operating losses
and has a working capital deficiency. In addition, the Company has not complied
with certain loan convenants and a substantial portion of the Company's debt
matures in 1997. These conditions raise substantial doubt about the Company's
ability to continue as a going concern. Management's plans in regard to these
matters are also described in Note 1. The financial statements do not include
any adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.

                                       and

                          Notes to Financial Statements



1. Organization

Government Property Investors, Inc., and subsidiaries ("GPI" or the "Company")
and the GovProp Entities were formed for the purpose of acquiring, owning,
developing, leasing and operating a portfolio of U.S. Government-leased
properties. As of December 31, 1996, the Company owned twenty-five office
buildings, comprising approximately 2.9 million rentable square feet, occupied
by various U.S. Government agencies. Seven office buildings, representing
approximately 54 percent of the value of the Company's portfolio, are located in
the greater metropolitan Washington, DC area of the United States. The Company
intends to continue developing and acquiring additional properties as well as
expanding properties within its existing portfolio.

The GovProp Entities include Rosecliff Realty, Inc. ("RRI") and GovProp, L.P.
("GovProp"). RRI was formed on January 7, 1994 and commenced operations on May
20, 1994 ("Inception"). Its primary function was to manage the properties owned
by GovProp. GovProp was formed and commenced operations on May 20, 1994. Its
primary function was to acquire, own, lease and operate a portfolio of
government-leased properties. During 1994, RRI carried out property management,
development, acquisition and corporate management functions and GovProp held
title to real property under development, fully developed real property and
issued debt relating to such real property.

Disclosures made herein, for the period from Inception to December 31, 1994
pertain to the GovProp Entities. Disclosures for periods subsequent to December
31, 1994, except those specifically identified as relating to transactions prior
to the formation of the Company, pertain to GPI.

The Company was incorporated in Delaware on January 13, 1995 and, after the
merger transaction discussed below, commenced operations on February 7, 1995
(the date GovProp and RRI were merged with and into the Company). In connection
with the merger, RRI distributed its one percent ownership interest in GovProp
to its sole shareholder. On January 13, 1995, one share of Series A Common Stock
(then representing 100% ownership interest in the Company) was issued to
Rosecliff Realty L.P. ("RRLP"). In exchange for RRLP's ownership interests in
the GovProp Entities, RRLP received a total of 995,999 additional shares of GPI
Series A Common Stock; the GovProp Entities were concurrently merged with and
into GPI.

                                GovProp Entities

                    Notes to Financial Statements (continued)



1.    Organization (continued)

At the merger date, the GovProp Entities owned 99% of GovProp Funding L.P. In
conjunction with the merger transaction, RRLP acquired the remaining 1% interest
in GovProp Funding L.P.; this remaining partnership interest was then exchanged
by RRLP for 4,000 shares of GPI Series A Common Stock and GovProp Funding L.P.
was concurrently merged with and into GPI's wholly owned subsidiary, Rosecliff
Realty Funding, Inc.

In addition to the merger transactions referred to above, the Company sold
944,559 shares of Series A Common Stock for $8.5 million and issued $25.3
million of subordinated debt to The 1818 Fund II, L.P. ("The 1818 Fund" - see
Note 6). Fees of approximately $4.6 million were incurred in connection with
this transaction; $3.4 million was allocated to deferred financing costs and
$1.2 million was allocated to additional paid-in capital based on the dollar
amount of each type of financing.

Additionally, to attract and retain qualified management personnel and provide
for continued sources of financing, Series A and Series B Common Stock has been
issued for approximately $700,000 to additional equity investors and Company
management personnel. Upon the occurrence of a valuation realization event (as
defined in the Amended and Restated Certificate of Incorporation), which
includes an initial public offering of stock and a change of control, and based
upon specified terms, as defined, shares of Series B Common Stock convert to
shares of Series A Common Stock.

As of December 31, 1996, the Company was authorized to issue 9,000,000 shares of
Series A Common Stock, 500,000 shares of Series B Common Stock, 500,000 shares
of Preferred Stock, and 10,000,000 shares of Excess Stock. As of December 31,
1996, total Company shares issued and outstanding are as follows:

During 1996, the Company repurchased 111 shares of Series A Common Stock from an
additional equity investor, 22,176 shares of Series A Common Stock from
Rosecliff Realty, L.P., and 40,242 shares of Series B Common Stock from the
Company's former president (the "Former President") and the Company's former
general counsel. The treasury stock has been recorded at its original issue
price with the excess of repurchase cost over the original issue price charged
to earnings in the current period.


Going Concern

During the years ended December 31, 1996 and 1995, and the period from May 20,
1994 (inception) to December 31, 1994, the Company has experienced losses of
approximately $12.0 million, $8.5 million and $1.3 million, respectively. As of
December 31, 1996, these losses have created an equity deficit of $21.8 million.
Since inception, the Company has relied upon equity investments and loans from
affiliated parties to meet operating and administrative requirements.
Additional investments from existing stockholders is not currently anticipated.

As of December 31, 1996, the Company does not have sufficient working capital to
fully discharge all operating obligations and has not obtained additional
financing to meet such obligations. The Company's long-term debt due in 1997,
exclusive of debt due to affiliates, approximates $225 million. The Company has
not obtained extensions on these obligations and, due to events described in
Note 12, the Company is not in active negotiations to replace such debt at
maturity. In the event existing debt is not extended or refinanced prior to
maturity, the Company would be in default on such debt.

                    Notes to Financial Statements (continued)


1.    Organization (continued)

Going Concern (continued)

Additionally, as discussed in Note 5, various of the Company's borrowing
agreements contain covenants imposing restrictions on cash flow and the
maintenance of certain ratios, as defined. As of January 31, 1997, debt totaling
approximately $93 million was not in compliance with these requirements. These
conditions raise substantial doubt about the Company's ability to continue as a
going concern.

As discussed in Note 12, in February 1997, the Company signed an agreement to
sell substantially all of its assets and merge with Health and Retirement
Properties Trust. The sale would result in the repayment or restructuring of a
substantial portion of the Company's debt and result in lower interest expense.
The Company believes that, until the sale is finalized, existing cash balances
and anticipated cash receipts will be adequate to cover operating requirements,
including interest and principal payments. There can be no assurance that the
sale will be successfully accomplished on terms and conditions acceptable to the
Company. In the event that the sale is not completed, the Company would endeavor
to extend and refinance its debt.

 2.   Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements for the years ended December 31, 1996 and
1995 include the results of operations of the GovProp Entities and those of GPI
and subsidiaries on a consolidated basis. All significant intercompany accounts
and transactions have been eliminated in consolidation. The results of
operations of the GovProp Entities, prior to the merger transactions, and GPI
have been presented for the year ended December 31, 1995 on a historical basis
because of prior common ownership, management and control.

                    Notes to Financial Statements (continued)


2.   Summary of Significant Accounting Policies (continued)

Basis of Presentation (continued)

The accompanying 1994 financial statements present the combined historical
financial position and results of operations of RRI and GovProp, as the ultimate
ownership and control of RRI and GovProp was held by the same group of investors
and this control continued through the merger transaction discussed in Note 1.
All significant intercompany transactions and accounts have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the associated amount of revenues and expenses during
the reporting period; actual results could differ from those estimates.

Rental Property

Costs incurred for the acquisition, development and construction of rental
property, which includes assets recorded under capital leases, are capitalized
and depreciated or amortized on a straight-line basis over the estimated useful
lives of the related assets, as follows:

         Buildings and improvements...............................40 years
         Furniture, fixtures and equipment.........................5 years

Expenditures for ordinary maintenance and repairs are expensed to operations as
incurred. Significant renovations and improvements, which extend the useful
lives of the assets, are capitalized and depreciated over their estimated useful
lives.

The Company's properties are carried at the lower of historical cost or fair
value. The Company records impairment losses on long-lived assets used in
operations when events and circumstances indicate that the assets might be
impaired and the undiscounted cash flows estimated to be generated by those
assets are less than the carrying amount of those assets.

                    Notes to Financial Statements (continued)


2. Summary of Significant Accounting Policies (continued)

Rental Property (continued)

Fair values are determined on a periodic basis, and include consideration of the
assets' net operating income, comparable prices of other properties in the area,
existing environmental and zoning restrictions and other factors effecting
current economic conditions. In 1996, the Company adopted FASB No. 121,
"Accounting for the Impairment of Long-Lived Assets to be Disposed of". There
was no effect on the Company's financial statements in 1996 as a result of this
adoption.

Property Under Development

Project development costs, including related costs of architecture and
engineering, construction, interest and real estate taxes incurred during the
period of construction are capitalized. Upon completion of construction, all
related costs are included in the basis of the real property and depreciated
over its estimated useful life.

Cash and Cash Equivalents

Cash includes amounts on deposit with financial institutions. Cash equivalents
include highly liquid investments with original maturities of three months or
less from date of purchase.

Restricted Cash

Restricted cash includes amounts held in escrow for payment of insurance,
property taxes and replacement reserve deposits.

Deferred Financing and Organization Costs

Deferred financing costs include fees and associated costs incurred to obtain
financing. These costs, amortized on the interest method over the terms of the
respective loans, are included in interest expense. Organization costs include
primarily legal and other costs incurred in the formation of GPI and
subsidiaries. These costs are amortized on a straight-line basis over a five
year period.

Fair Value of Financial Instruments

The fair value of the Company's long-term debt has been estimated using
available market information, including rates currently offered to the Company
for debt of similar maturities.

Revenue Recognition

Minimum rent, including rental abatements and contractual fixed increases or
decreases attributable to operating leases, is recognized on a straight-line
basis over the term of the related lease. The excess amount of rental payments
contractually due over rents recognized is included in deferred rents payable, a
component of accounts payable and accrued expenses, in the accompanying balance
sheets. Contractually due but unpaid rent payments are included in accounts
receivable on the accompanying balance sheets. Most of the Company's leases
provide for additional revenues in the form of operating expense reimbursements
based on annual increases in the Consumer Price Index. These revenues are also
recognized on the accrual basis.

Stock Based Compensation

In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standard ("SFAS") No. 123, "Accounting for Stock Based
Compensation", which is effective for the Company's December 31, 1996 financial
statements. SFAS No. 123 allows companies to account for stock based
compensation either under the new provisions of SFAS No. 123 or under the
provisions of APB Opinion No. 25, with further pro forma disclosures within the
footnotes and financial statements as if the measurement provisions of SFAS No.
123 had been adopted. The Company intends to continue accounting for its stock
based compensation in accordance with the provisions of APB No. 25. As such, the
adoption of SFAS No. 123 will not impact the financial position or results of
operations of the Company.

Income Taxes

For federal income tax purposes, the Company is a real estate investment trust
("REIT"). As a REIT, the Company is required to distribute at least 95% of its
taxable income and meets certain other requirements. No provision for federal
income taxes is recorded in the financial statements because the Company expects
to distribute in excess of its taxable income to its shareholders. For the
period prior to the mergers discussed in Note 1, taxable income or loss is
reported on the owners' respective tax returns.

Secured Notes

At December 31, 1996 and 1995, the Company had $55.8 million and $60.3 million,
respectively, of fixed-rate debt backed by the securitization of the underlying
government lease payments and issuing U.S. Government General Service
Administration certificates of participation (the "Securitized Debt"). In
December 1996, the Company entered into an agreement with a lender to provide
funding to refinance $27.0 million of this fixed-rate debt (see Notes 8 and 12).
At December 31, 1996 and 1995, the weighted average interest rate of funds
borrowed under the Securitized Debt is 7.2 percent per annum. At December 31,
1996 and 1995, the Securitized Debt is collateralized by rental property
totaling $78.1 million and $80.7 million, respectively. The Securitized Debt
matures from 2002 through 2009. Additionally, all rents from the pledged
properties are assigned for payment of debt service, operating expenses, taxes,
insurance and reserves; remaining funds are remitted to the Company.

At December 31, 1996 and 1995, the Company had a permanent loan (the "Bayerische
Facility") with an outstanding balance of $4.2 million and $4.5 million,
respectively. The Bayerische Facility bears interest at 6.86 percent per annum,
and is collateralized by the underlying rental property totaling approximately
$5.9 million and $6.0 million at December 31, 1996 and 1995, respectively. The
Bayerische Facility matures in 2005.

Additionally, all rents from the pledged property are assigned to the lender
primarily for payment of debt service and reserves; remaining funds are remitted
to the Company.

At December 31, 1996, the Company had a loan (the "John Hancock Loan") with an
outstanding balance of $19.5 million. The John Hancock Loan bears interest at
7.65 percent, matures in 2016, and is collateralized by the underlying rental
property. Upon completion of construction in May 1996, the loan converted to a
permanent loan and is collateralized by the underlying rental property with a
completed cost of $20.5 million. Additionally, all rents from the pledged
property are assigned for payment of debt service and reserves; remaining funds
are remitted to the Company.

In April, 1996 the Company entered into an agreement providing for loans up to
$10.3 million for the purchase of land and construction of a building. These
loans bear interest at LIBOR plus 1.9 percent and mature in April of 1997 and
are collateralized by the underlying property and its rental income. As of
December 31, 1996, this construction loan had an outstanding balance of $1.6
million, with $8.7 million available for future borrowing.

In August, 1996, the Company entered into an agreement providing for loans up to
$11.3 million for the purchase of land and building and construction of building
improvements. These loans bear interest at LIBOR plus 1.75 percent, mature in
December of 1996, and may be extended until February, 1997 and are
collateralized by the underlying property and its rental income. In 1996, the
Company extended this loan until February, 1997. As of December 31, 1996, this
loan had an outstanding balance of $7.8 million, with $3.5 million available for
future borrowing.

Capital Lease

In March, 1996, the Company entered into a capital lease with the Erie County
Industrial Development Agency ("ECIDA"). The Company's obligations under the
capital lease approximate ECIDA's obligations under a $13.5 million, fixed rate
county revenue bond (the "ECIDA Bond"). The ECIDA Bond is backed by the
securitization of the underlying lease payments, bears interest at 7.66 percent
and matures in 2004. At December 31, 1996, the outstanding capital lease
obligation and balance on the ECIDA Bond approximated $13.0 million. If the
underlying tenant leases are extended, the term of the

capital lease and the ECIDA Bond can be extended through the lease extension
date, and will bear interest at the prevailing U.S. Treasury rate plus two
percent. The ECIDA Bond is collateralized by rental property totaling
approximately $21.3 million. Additionally, all rents from the pledged property
are assigned for payment of debt service and reserves; remaining funds are
remitted to the Company.

Lines of Credit and Other

During 1994, the GovProp Entities entered into an acquisition facility (the
"Acquisition Facility") with the maximum principal amount of $112.5 million, to
be used to finance up to 75 percent of the acquisition cost of properties
purchased and to meet certain funding criteria as specified by the Lender,
including closing costs and debt origination fees not to exceed to 3.5 percent
of the purchase price. At December 31, 1994, the Acquisition Facility's $6.1
million balance was collateralized by three properties, totaling approximately
$16.3 million. The Acquisition Facility had an initial maturity of June 1995, an
interest rate 300 basis points over one-month LIBOR and an origination fee of 2
percent of the principal amount borrowed. All available cash flow from the
properties acquired under the Acquisition Facility, after expenses, reserves and
distributions for estimated taxes, are used to repay the loan. At December 31,
1994, the interest rate on this facility was 9 percent.

During 1995, the Company negotiated an extension of the maturity date,
reductions of the interest rate and origination fees and increased the amount
available under the Acquisition Facility to $150 million. At December 31, 1995,
the balance outstanding under the Acquisition Facility was $57.8 million; future
borrowings of $92.2 million were available under this agreement. At December 31,
1995, the Acquisition Facility was collateralized by eleven properties, totaling
$86.8 million. At December 31, 1995, the 30 day LIBOR rate was approximately
5.72 percent.

In September 1996, the Acquisition Facility was renegotiated and extended to
include maximum funding of $200 million, at a rate of LIBOR plus 2.95 percent,
maturing in December 1996 and may be extended for two additional three month
periods. In December 1996, the Company extended the Acquisition Facility for one
additional three

month period. At December 31, 1996, the balance outstanding under the
Acquisition Facility was $158.9 million; future borrowings of $41.1 million are
available under this agreement. At December 31, 1996, the Acquisition Facility
is collateralized by sixteen properties, totaling $196.0 million. At December
31, 1996, the 30 day LIBOR rate was approximately 5.53 percent.

In 1995, the Company entered into another line of credit agreement (the "BHF
Facility"), totaling $50.0 million, to finance the balance of property
acquisition costs not covered under the Acquisition Facility. At December 31,
1996 and 1995, the BHF Facility had an outstanding balance of $50.0 million and
$22.1 million, respectively. The BHF Facility matures in October of 1997.
Funding under the BHF Facility bears interest at a fixed rate of 10 percent per
annum, is subordinated to the Company's other non-affiliated debt, and is
collateralized by stock in the Company's subsidiaries, with a secondary security
interest in all rents from the pledged properties.

Convertible Debt

At December 31, 1996, the Company had also issued approximately $390,000 of
convertible subordinated debt to the lenders of the BHF Facility. At the
holders' option, this debt is convertible, at $9.00 per share, into
approximately 43,000 shares of Series A Common Stock. Conversion is dependent
upon the occurrence of certain events, including an initial public offering of
stock or a change in control, as defined. Additionally, this convertible
subordinated debt is redeemable, at the option of either the holders or the
Company, starting in 1998.

In December, 1996, the Company entered into an interest rate protection
agreement (the "Hedge Agreement") with a financial institution, protecting the
Company from increases in interest rates effecting certain prepayment penalties
which will be incurred in connection with $27.0 million of Securitized Debt that
was refinanced in January, 1997 (see Notes 8 and 12). This transaction is
accounted for as a hedge; gains or losses are deferred as adjustments to the
carrying value of the $27.0 million of Securitized Debt as a component of the
gain or loss in the period the debt is refinanced.

Convertible Debt (continued)

During 1995, the Company refinanced approximately $11.3 million of debt. In
conjunction with this transaction, approximately $297,000 of deferred financing
charges were written off and classified as an extraordinary item in the
accompanying statement of operations.

Various of the Company's borrowing agreements contain covenants imposing
restrictions on cash flow and the maintenance of certain ratios, as defined. As
of December 31, 1996, the Company is not in compliance with certain of these
financial covenants.

 6.   Notes Payable - Affiliates

At December 31, 1996 and 1995, the Company had $47.5 million and $43.3 million,
respectively, of unsecured subordinated debt outstanding with equity partners
(the "Subordinated Debt"). The Subordinated Debt provides funding for
acquisitions and development properties, as defined, and for general corporate
purposes. Under these credit agreements, as of December 31, 1996 and 1995, $18.5
million is payable to GovProp Sub-Debt Partners, L.P., a limited partnership
whose partners are also partners in RRLP. Additionally, as of December 31, 1996
and 1995, $29.0 million and $26.8 million, respectively, in notes payable is due
to The 1818 Fund, a shareholder of the Company. All funding under the
Subordinated Debt agreements bears a fixed rate of interest; the weighted
average interest rate is approximately 12.5 percent per annum. As of December
31, 1996, $12.5 million of Subordinated Debt matures in 1997; the remaining
$35.0 million matures in years 2003 through 2005.

At December 31, 1996 and 1995, $5.4 million and $4.6 million, respectively, of
the Subordinated Debt (the "Subordinated Convertible Debt") contained conversion
provisions. At the holders' option, the Subordinated Convertible Debt is
convertible into approximately 478,000 shares of GPI Series A Common Stock at
conversion prices ranging from $9.00 to $11.27 per share. Conversion is
dependent upon the occurrence of certain events, including an initial public
offering of stock or a change in control, as defined.

6. Notes Payable - Affiliates (continued)

Certain borrowing agreements contain covenants requiring the maintenance of
ratios, as defined. As of December 31, 1996, the Company is not in compliance
with certain of these financial covenants.

7. Leases

The Company leases office space and equipment for its corporate offices under
operating leases that terminate in 1997. For the years ended December 31, 1996
and 1995, and the period from May 20, 1994 (inception) to December 31, 1994,
rental expenses for corporate office space and equipment under operating leases
were $302,950, $201,040 and $58,917, respectively. Future minimum noncancelable
rentals of approximately $226,000 are due in 1997.

In 1996, the Company entered into a lease with the Erie County Industrial
Development Agency. Based upon the terms of the lease, which include a bargain
purchase option at the end of the lease, the Company has classified the lease as
a capital lease. The underlying asset is included in real estate in the
accompanying consolidated December 31, 1996 balance sheet as follows (in
thousands):

8. Commitments and Contingencies

At December 31, 1996, the Company had signed commitments to purchase or develop
properties totaling approximately $27.9 million. In connection with these
acquisitions, the Company has placed $725,000 on deposit. In addition, the
Company is endeavoring to obtain the return of $115,000 of funds held in escrow
for projects it is no longer actively pursuing.

In December, 1996 the Company entered into a commitment with a lender for $31
million of financing to fund the refinancing of an existing property. In
connection with this transaction, the Company has placed $600,000 on deposit
and, as of December 31, 1996, is included in other assets in the accompanying
financial statements. This refinancing transaction was consummated in 1997 (see
Notes 5 and 12).

In 1996, the Company entered into and extended employment contracts with certain
management employees that expire in 1997 and 1998. These contracts provide that,
if employment is terminated "without cause," these employees will be paid their
base salaries and certain benefits through the remainder of the contract period.
Additionally, the

                    Notes to Financial Statements (continued)


8. Commitments and Contingencies (continued)

Company is obligated to pay its Former President a $275,000 fee, contingent upon
an initial public offering of stock.

In 1995, a property that is leased to the General Services Administration
("GSA") and was occupied by one of the agencies of the U.S. Government, was
vacated by its occupant. GSA has continued to pay rent under its non-cancelable
lease and is obligated to do so until May 1998, the lease expiration date. The
Company has determined that, unless the Government renews its lease at similar
rental rates in 1998, the carrying amount of the property will be impaired.
Accordingly, at December 31, 1995, the Company recorded a $2.8 million
impairment loss to write down the property to its estimated fair value of $6.5
million. Fair value was based on the estimated cash flow the property will
generate over the remainder of the GSA lease term and from a replacement tenant.
The Company's plan of action is to locate suitable replacement tenants to occupy
the space at the end of the lease term. Additionally, GSA is currently
evaluating other agencies for occupancy in the space.

Purchase agreements with the prior owners of two properties, acquired by the
Company during 1995, provide for contingent payments to the sellers. Pursuant to
the purchase agreements, the sellers may earn additional purchase price
consideration if the lessees exercise lease renewal options. The additional
purchase price consideration for one of the properties totals $1.0 million, plus
accrued interest at 10 percent per annum, accruing from the Company's original
purchase date. The additional purchase price consideration for the second
property could approximate $4.5 million; the final determination of the amount
of additional purchase consideration is further dependent upon certain terms and
conditions, as defined in the purchase agreement. Contingencies under these
purchase agreements expire in 2005; no amounts have been accrued under the
purchase agreements.

 9.   Employee Benefit Plan

The Company has a 401(k) benefit plan (the "Plan") for all permanent, full-time
employees. Starting on the first day of the month following commencement of
employment, eligible employees may participate in the Plan. The Company matches
50% of all employee contributions (which are subject to statutory limitations);
100% of all employer contributions vest immediately. During the years ended
December 31, 1996 and

                    Notes to Financial Statements (continued)


9. Employee Benefit Plan (continued)

1995, and the period from Inception to December 31, 1994, the Company's share of
Plan contributions was approximately, $67,600, $45,000 and $9,100, respectively.

10. Related Party Transactions

In November 1996, the Company entered into an agreement with its Former
President (the "Termination Agreement"), providing for: (i) repurchase of 33,582
shares of the Former President's Series B Common Shares for $150,000 (of which
approximately $135,000 is reflected as compensation expense in 1996 and
approximately $15,000 is reflected as the cost of treasury stock), plus a
contingent payment of approximately $350,000 if certain investment goals are met
(such payment will be reflected as compensation expense when incurred), (ii)
reduction of $200,000 of the Former President's note receivable in exchange for
22,176 Series A Common Shares held by RRLP, as such amounts approximate the
original issue price, (iii) reduction of approximately $381,000 of the Former
President's note receivable and accrued interest in exchange for an equal
reduction in Subordinated Debt due to GovProp Sub-Debt Partners, L.P., an
affiliate of RRLP, and (iv) compensation to the Former President of $200,000 for
his continuing services as a member of the Company's Board of Directors through
October, 1997.

At December 31, 1996 the Company had notes receivable from its Former President
aggregating $947,833 (including accrued interest at 10 percent per annum).
During the years ended December 31, 1996 and 1995, interest income of
approximately $130,000, and $122,000, respectively, was earned on these notes.
At December 31, 1996, $260,000 of these notes receivable mature in May, 2001 and
were used to purchase stock of the Company; this amount is classified as a
reduction of stockholders' equity in the accompanying financial statements.
Further, $687,833 of these notes receivable for advances to its Former
President, and accrued interest on all notes receivable from its Former
President, are reflected as affiliated notes receivable in the accompanying
financial statements. As of December 31, 1996, approximately $586,000 of the
funds advanced to the Company's Former President were used to fund a portion of
the Subordinated Debt issued by the Company to GovProp Sub-Debt Partners, L.P.,
an affiliate of RRLP, which bears interest at 14% per annum and matures in
March, 2003 (see Note 6).

                    Notes to Financial Statements (continued)


10. Related Party Transactions (continued)

During the year ended December 31, 1995, the Company paid the Fund $1.9 million
of transaction fees for its debt and equity raising efforts and paid an
affiliate of RRLP $500,000 of transaction fees for its debt and equity raising
efforts; of these amounts $2.0 million is classified as deferred financing costs
and $0.4 million is classified as a reduction of additional paid-in capital in
the accompanying financial statements.

During the year ended December 31, 1995, an affiliate of RRLP entered into a
consulting services agreement (the "Consulting Services Agreement") with the
Company to provide management, strategic planning and financing services. The
Company is required to pay certain fees upon achieving predetermined acquisition
or financing goals, plus an annual consulting fee of approximately $350,000
(adjusted annually by the consumer price index). The Consulting Services
Agreement expires in January, 2000. Under the Consulting Services Agreement, the
Company incurred consulting fees of $1,550,000 during the year ended December
31, 1995. In connection with debt and equity raising efforts, during the year
ended December 31, 1995, $900,000 was classified in the accompanying financial
statements as deferred financing costs, and $300,000 was classified as a
reduction of additional paid-in capital; the remaining $350,000 annual
consulting fee was included in general and administrative expenses.

In 1996, under the Consulting Services Agreement, the Company paid an annual
consulting fee of approximately $359,000. As of December 31, 1996, the Company
has a contingent obligation to pay approximately $554,000 in additional
consulting fees upon the consummation of a value realization event, as defined.

 11.      Fair Value of Financial Instruments

The following disclosures of estimated fair value were determined by management,
using available market information and valuation methodologies. Considerable
judgment is necessary to interpret market data and develop estimated fair value.
The use of different market assumptions or estimation methodologies may have a
material effect on the estimated fair value amounts.

Cash equivalents, accounts receivable, notes receivable, accounts payable,
accrued expenses and variable rate debt are carried at amounts which reasonably
approximate their fair values. As of December 31, 1996 and 1995, fixed rate
notes payable to nonaffiliated

11. Fair Value of Financial Instruments (continued)

entities with a carrying value of $142.5 million and $86.9 million,
respectively, have an estimated aggregate fair value of $141.4 million and $86.9
million, respectively. Due to the interrelationship of the Company's equity
funding, the estimated fair value of its Subordinated Debt at December 31, 1996
and 1995 is not readily determinable.

Disclosure about fair values of financial instruments is based on pertinent
information available to management as of December 31, 1996. Although management
is not aware of any factors that would significantly affect the reasonable fair
value amounts, such amounts have not been comprehensively revalued for purposes
of these financial statements since December 31, 1996, and current estimates of
fair value may differ from the amounts presented herein.

 12.      Subsequent Events

In January, 1997, the Company repurchased $27.0 million of Securitized Debt with
the proceeds of a $31.0 million term loan (the "Term Loan"). In connection with
this transaction, the Company paid a premium of approximately $820,000 to redeem
the Securitized Debt and incurred approximately $91,000 of associated redemption
costs, for a total loss on refinancing of approximately $911,000. Additionally,
under the related Hedge Agreement, the Company recognized gains of approximately
$43,000. These amounts will be reflected as an extraordinary loss in the period
subsequent to year-end.

The Term Loan bears interest at the lender's prime rate, and initially matures
in April of 1997 and is collateralized by an assignment of the Securitized Debt
repurchased with the proceeds and a secondary security interest in the rental
property and assignment of rents which collateralize the Securitized Debt. The
Term Loan may be extended, at the Company's option, for two additional one month
periods. All available cash flow from the underlying property, after expenses,
reserves and distributions for estimated taxes, is used to repay the loan.

In February 1997, the Company reached an agreement to sell substantially all of
its assets and merge with Health and Retirement Properties Trust. The
transaction is subject to various conditions, including completion of due
diligence; however, the parties anticipate consummating this transaction on or
around March 31, 1997. In connection with this transaction certain fees will be
incurred, deferred financing fees will be written off and

compensation expense attributable to the issuance and conversion of Series B
Common Stock, settlement of employment contracts, associated severance and other
costs will be incurred. The amount of these costs has not been finalized, but is
expected to be material; these items will be charged against earnings in the
period the transaction is consummated.

                                 and Other Data

     The following unaudited pro forma balance sheet at December 31, 1996 and
unaudited pro forma statement of income for the year ended December 31, 1996 are
intended to present the financial position and results of operations of the
Company as if the transactions described in the Notes were consummated on
December 31, 1996 and January 1, 1996, respectively. These unaudited pro forma
financial statements should be read in conjunction with the separate financial
statements of the Company and of Government Property Investors, Inc. (the 
"Seller"), both for the year ended December 31, 1996, and both included
elsewhere herein. These unaudited pro forma financial statements are not
necessarily indicative of the expected financial position or results of
operations of the Company for any future period. Differences would result from,
among other considerations, future changes in the Company's portfolio of
investments, changes in interest rates, changes in the capital structure of the
Company, delays in the acquisition of certain properties, and changes in
property level operating expenses.

     The following unaudited pro forma balance sheet and unaudited pro forma 
statement of income were prepared pursuant to the Securities and Exchange
Commission's rules for the presentation of pro forma data. The pro forma and
adjusted pro forma data give effect to the acquisition by the Company of the
Government Office Properties (the "Transaction") from the Seller and an offering
of common shares of beneficial interest ("Shares") to fund the payment of
certain debt of the Seller and the Company. Certain properties expected to be
acquired by the Company are currently under construction or development by the
Seller or third parties. Other properties were under construction or renovation
during 1996 when they were owned or under development by the Seller. The
accompanying pro forma operating data does not give further effect to the
completion of construction or the related lease commencement for any period
prior thereto. Construction projects not completed by December 31, 1996 are
likewise not reflected in the pro forma balance sheet data. Rather, the effect
of completion of these construction projects is presented separately from the
pro forma data as described in the accompanying notes. The Company believes that
a display of such adjusted pro forma data is meaningful and relevant to the
understanding of the Transaction and, accordingly has presented such data in the
final two columns, labelled "Other Data," on the accompanying pages.

     level expense adjustments are established for the purposes of this pro

     purposes of this pro forma presentation that the cost of borrowing is 
     equal to the cost of borrowing of the Company under its Bank Credit 
     Facility at a weighted average interest rate of 6.38%. Such costs are

     stand-alone basis. See Note D and Note H, above.

Effective  Time shall be the  directors  and  officers of the Survivor as of the
Effective Time.

         2.5 Manner of Converting Shares.

         All of the HRPT Common Shares and all shares of beneficial  interest of
Merger Sub issued and outstanding  immediately prior to the Effective Time shall
remain issued and  outstanding  after the Effective Time and shall be unaffected
by the  Merger.  The manner  and basis of  converting  the shares of  beneficial
interest of GPH upon consummation of the Merger shall be as follows:

                  (a) GPH Common  Shares.  Except as otherwise  provided in this
         Section 2.5, each GPH Common Share issued and  outstanding  immediately
         prior to the Effective Time shall,  as of the Effective Time, by virtue
         of the Merger and without any action on the part of the holder thereof,
         be  converted  into the right to  receive  one  percent of (i) the HRPT
         Merger  Shares,  (ii) any HRPT  Common  Shares  issued to  pursuant  to
         Sections 8.3 and 8.4 and (iii) HRPT Common  Shares  issued  pursuant to
         Section 9.2.

                  (b)  Anti-Dilution  Provisions.  If HRPT changes the number of
         HRPT Common Shares issued and outstanding,  after the  determination of
         the  Merger  Price and prior to the  Effective  Time,  as a result of a
         stock  split,  stock  dividend,   recapitalization,   reclassification,
         redemption,  exchange,  self-tender or exchange offer, or any action by
         HRPT similar to any of the foregoing,  or affects the value of the HRPT
         Common  Shares as a result of any  dividend  or  distribution  of cash,
         securities  or  other  property  (other  than  regular  cash  dividends
         declared  and paid in a manner and amount  consistent  with recent past
         practice  and  other  than  the  issuance  of  HRPT  Common  Shares  in
         connection with business combination  transactions) and the record date
         therefor  shall be after  the date of this  Agreement  and prior to the
         Effective Time, the numbers of HRPT Common Shares to be issued pursuant
         to this Agreement shall be appropriately adjusted.

                  (c)  Treasury  Shares.  Any and all GPH Common  Shares held as
         treasury  shares by GPH shall be cancelled and retired at the Effective
         Time, and no consideration shall be issued in exchange therefor.

                  (d) Fractional  Shares.  No fractional HRPT Common Shares will
         be  issued  as a  result  of the  Merger.  In lieu of the  issuance  of
         fractional shares pursuant to this Agreement, cash adjustments (without
         interest)  will be paid to GPI in  respect of any  fraction  of an HRPT
         Common Share that would otherwise be issuable to GPI, and 

                                      -10-

<PAGE>


         the amount of such cash adjustment shall be determined by multiplying
         the fraction of an HRPT Common Share otherwise issuable times the
         Merger Price.

         2.6 Investment and Registration Rights Agreement.

         The issuance of the HRPT Merger Shares  pursuant to this Agreement will
not be registered  under the 1933 Act or any state  securities  laws in reliance
upon certain exemptions from registration contained therein. The transfer of the
HRPT Merger Shares will, accordingly,  be subject to certain restrictions as set
forth in the Investment and Registration Rights Agreement,  in the form attached
as Schedule 2.6 (the "Registration  Rights  Agreement").  GPI shall have certain
rights to require the  registration  of an  offering  of the HRPT Merger  Shares
pursuant to the Registration Rights Agreement.

              CLOSING, EFFECTIVE TIME AND DELIVERY OF CONSIDERATION

         3.1 The Closing.

         Following the day on which the last of the conditions set forth in this
Agreement shall be fulfilled or waived in accordance  herewith (other than those
conditions  which  are to be  fulfilled  contemporaneously  with  the  Closing),
subject to the terms and conditions of this Agreement, the closing of the Merger
shall take place (a) at the  offices of  Sullivan &  Worcester  LLP,  at Boston,
Massachusetts  at 9:00 a.m.  (local time), on the day set forth in a notice from
HRPT to GPI which shall not be sooner than 3 business days following the date of
such notice and not later than March 31, 1997  (unless  delayed as  permitted by
Section  10.2),  or (b) at such other  time,  date or place as the  Parties  may
agree.

         3.2 Effective Time.

         If all of the  conditions  to the  Merger  set forth in this  Agreement
shall  have been  fulfilled  or waived  and this  Agreement  shall not have been
terminated,  on the Closing Date the Parties shall deliver to the  Department of
Assessments  and  Taxation  of the State of Maryland  the  Articles of Merger in
accordance  with Maryland Law. The Merger shall become  effective at the time of
filing of the Articles of Merger.

         3.3 Issuance of HRPT Merger Shares.

         At the Closing,  HRPT shall  authorize the transfer  agent for the HRPT
Common  Shares to issue the number of whole HRPT  Common  Shares to which GPI is
entitled  pursuant to Section 2.5. As promptly as possible  after the  Effective
Date,  GPI, as the sole  record  holder of all of the  outstanding  certificates
which  immediately  prior to the Effective  Time  represented  GPH Common Shares
(collectively, the "Certificates" and each a "Certificate") shall surrender such
Certificates  (together with a stock power,  duly executed in blank) to HRPT and
shall  thereupon  be entitled to receive in  exchange  therefor  (i) one or more
certificates as requested by GPI (properly issued,  executed and counter-signed,
as appropriate) representing,  in the aggregate, the HRPT Merger Shares to which
GPI shall have become  entitled  pursuant to the  provisions  of Section 2.5 and
(ii) as to any fractional

                                      -11-

<PAGE>



share,  a check  representing  the cash  consideration  to which GPI shall  have
become entitled  pursuant to Section 2.5. The Certificates so surrendered  shall
forthwith be cancelled.  No interest will be paid or accrued on the cash payable
upon the surrender of the Certificates.  From the Effective Time until surrender
in accordance  with the provisions of this Section 3.3, each  Certificate  shall
represent for all purposes only the right to receive the consideration  provided
in Section 2.5. No dividends  that are  otherwise  payable on HRPT Common Shares
will be paid GPI until GPI surrenders the  Certificates.  After such  surrender,
there shall be paid GPI any dividends on such HRPT Common Shares that shall have
a record date on or after the Effective Time and prior to such surrender. If the
payment  date for any such  dividend is after the date of such  surrender,  such
payment  shall be made on such  payment  date.  In no event  shall  the  persons
entitled to receive  such  dividends  be  entitled  to receive  interest on such
dividends.


                                    SECTION 4
                      REPRESENTATIONS AND WARRANTIES OF GPI

         The  execution,  delivery and  performance of this  Agreement,  and the
consummation of the transactions provided for in this Agreement,  have been duly
authorized  by all  necessary  action  on the  part  of GPI and  this  Agreement
constitutes the legal, valid and binding obligation of GPI,  enforceable against
GPI in accordance  with its terms,  except as  enforceability  may be limited by
bankruptcy,  insolvency,  reorganization,  or other  laws

repurchase, redeem or otherwise acquire any outstanding GPI Common Stock. Except

         and the GPI Subsidiaries,  taken as a whole, or (xiii) any other event,
         condition or state of facts of any character  peculiar to GPI or any of
         the  GPI   Subsidiaries  or  to  their  operations  and  not  generally
         applicable to private enterprises in the same business as GPI or any of

formula, know-how, data, plan, specification,  drawing or the like, necessary or
required  for the conduct of its business as such  business is  currently  being

infringing  upon the  rights  of any  third  party  with  respect  to any of the
foregoing,  and GPI does not know of any basis for the assertion  against GPI or

         4.15 Pension and Benefit Plans.

                  (a)  Company   Employee  Benefit  Plans  and  Company  Benefit
         Arrangements. Schedule 4.15(a) lists each Company Employee Benefit Plan
         and Company  Benefit  Arrangement.  GPI and the GPI  Subsidiaries  have
         delivered to HRPT with respect to each such  Company  Employee  Benefit
         Plan and Company  Benefit  Arrangement  true and complete copies of (i)
         all written documents comprising such plans and arrangements (including
         amendments  and  individual,  trust or  insurance  agreements  relating
         thereto);  (ii) the most recent Federal Form 5500 series (including all
         schedules  thereto)  filed with respect to each such  Company  Employee
         Benefit  Plan;  (iii)  the two most  recent  financial  statements  and
         actuarial reports, if any, pertaining to each such plan or arrangement;
         (iv) the summary plan description  currently in effect and all material
         modifications  thereto,  if any, for each such Company Employee Benefit
         Plan;  and (v) written  communications  to  employees to the extent the
         substance  of any  Company  Employee  Benefit  Plan  described  therein
         differs  materially from the other  documentation  furnished under this
         Section.

                  (b)  Multiemployer  Plans.  Neither GPI nor any GPI Subsidiary
         nor any ERISA  Affiliate of GPI or any GPI  Subsidiary  has at any time
         during the 6-year period  preceding the date hereof  participated in or
         been  required to make or accrue a  contribution  to any  Multiemployer
         Plan.  Neither GPI nor any GPI Subsidiary  nor any of their  respective
         ERISA  Affiliates  has  incurred  or  reasonably  expects  to incur any
         material  withdrawal  liability  (within the meaning of Section 4201 of
         ERISA) or any other material current, contingent or potential liability
         with respect to any Multiemployer Plan.

                  (c) Welfare Benefits Plans.  Except as set forth in Disclosure
         Schedule  4.15(c) and pursuant to the  provisions of COBRA,  no Company
         Employee  Benefit Plan provides  benefits  described in Section 3(1) of
         ERISA to any former employees or retirees of GPI or any GPI Subsidiary.
         Except as set forth in  Disclosure  Schedule  4.15  (c),  no  condition
         exists that would  prevent GPI or any GPI  Subsidiary  from amending or
         terminating  any  Company  Employee  Benefit  Plan or  Company  Benefit
         Arrangement  providing  health or  medical  benefits  in respect of any
         active or retired employee other than limitations imposed by law.

                  (d)  Company  Employee  Benefit  Plans.  None  of the  Company
         Employee  Benefit  Plans is a Pension Plan which is subject to Title IV
         of ERISA and neither GPI nor any GPI Subsidiary nor any ERISA Affiliate
         has at any time maintained or sponsored a Pension Plan which is subject
         to Title IV of ERISA.  Neither GPI nor any GPI Subsidiary nor any ERISA
         Affiliate  has incurred any material  liability  under  Section 4062 of
         ERISA to the  Pension  Benefit  Guaranty  Corporation  or to a  trustee
         appointed  under Section 4042 of ERISA.  All Company  Employee  Benefit
         Plans that are Pension Plans intended to be qualified under Section 401
         of the  Internal  Revenue  Code  are so  qualified  and  have  been  so
         qualified  during the period since their  adoption;  each trust created
         under  any such plan is exempt  from tax  under  Section  501(a) of the
         Internal Revenue Code and has been so exempt since its creation. A true
         and correct copy of the most recent  determination  letter from the IRS
         regarding such  qualified  status for each such plan has been delivered
         to HRPT.

                  (e)  Additional  Benefits.  Except as set forth on  Disclosure
         Schedule  4.15(e),  no employee of GPI or of any ERISA Affiliate of GPI
         will receive or be entitled to, and neither GPI nor any GPI  Subsidiary
         shall be liable  for,  any  additional  benefits,  bonuses,  service or
         accelerated  rights to  payment of  benefits  under any  Company  Plan,
         including  the right to receive any  parachute  payment,  as defined in
         Section 280G of the Internal  Revenue Code,  or become  entitled to any
         severance, termination allowance or similar payments as a result of the
         transactions contemplated by this Agreement.

                  (f) Compliance with Laws; Contributions. Each Company Plan has
         at all times prior hereto been maintained, in all material respects, in
         accordance with all applicable  laws. Other than claims for benefits in
         the ordinary course,  there is no claim pending or, to the knowledge of
         GPI,  threatened  involving any Company Plan by any Person against such
         plan or GPI or any GPI  Subsidiary.  There  is no  pending  or,  to the
         knowledge  of GPI,  threatened  proceeding  involving  any Company Plan
         before the IRS,  the  United  States  Department  of Labor or any other
         governmental authority.  Each of GPI and the GPI Subsidiaries and their
         respective  ERISA  Affiliates  have made full and timely payment of all
         amounts required to be contributed under the terms of each Company Plan
         and  applicable  law or  required  to be paid as  expenses  under  such
         Company  Plan.  To the  extent  it  might  give  rise  to any  material
         liability:  (i) no Prohibited  Transaction has occurred with respect to
         any Company Employee Benefit Plan or any other employee benefit plan or
         arrangement  maintained  by GPI or any GPI  Subsidiary  or any of their
         respective ERISA Affiliates which is covered by Title I of ERISA;  (ii)
         no  Reportable  Event that was not waived by  regulation of the Pension
         Benefit Guaranty Corporation, and no event described in Section 4062 or
         4063 of ERISA,  has occurred in  connection  with any Company  Employee
         Benefit Plan;  and (iii) neither GPI nor any GPI  Subsidiary nor any of
         their current or former ERISA Affiliates (while an ERISA Affiliate) has
         engaged in, or is a successor or parent  corporation to any entity that
         has engaged in, a transaction described in Section 4069 of ERISA.

         4.16 Tax Matters.

                  (a) GPI and each of the GPI  Subsidiaries  have (x) filed when
         due  with  local,  foreign  and  other  governmental  agencies  all tax
         returns, estimates, information and reports ("Tax Returns") required to
         be filed by them with respect to all federal,  state,  local or foreign
         taxes,  levies,  imposts,  duties,  licenses and registration fees, and
         charges of any nature whatsoever including, without limitation,  income
         taxes,  unemployment and social security  withholding taxes,  interest,
         penalties, and additions to tax with respect thereto ("Taxes"), and (y)
         paid when due and  payable  or, to the  extent of Taxes not yet due and
         payable,  have accrued or otherwise  adequately  reserved in accordance
         with  GAAP for the  payment  of all  Taxes.  All such Tax  Returns  are
         correct  and  complete  in  all  respects   excluding   defects  which,
         individually  and in the  aggregate,  will not have a Material  Adverse
         Effect.  Complete and accurate copies of all such Tax Returns have been
         furnished  or made  available  to HRPT.  Neither GPI nor any of the GPI
         Subsidiaries has obtained an extension of the time within which to file
         any Tax Return. Neither GPI nor any of its Subsidiaries

                                      -19-

<PAGE>


         has  received  written  notice  from  any  governmental   agency  in  a
         jurisdiction  in which such entity  does not file a Tax Return  stating
         that such entity is or may be subject to taxation by that jurisdiction.

                  (b) No Taxes  have been  assessed  or  asserted  in writing in
         respect of any Tax Returns filed by GPI or any of the GPI  Subsidiaries
         or claimed in writing to be due by any taxing  authority  or  otherwise
         that are not accrued or  adequately  reserved  for in  accordance  with
         GAAP. No Tax Return of GPI or any of the GPI  Subsidiaries has been or,
         to GPI's  knowledge,  is  currently  being  audited by the IRS or other
         taxing authority (whether foreign or domestic).  Neither GPI nor any of
         the GPI  Subsidiaries  has  executed or filed with the IRS or any other
         taxing authority  (whether foreign or domestic) any agreement,  waiver,
         or other  document  extending,  or having the effect of extending,  the
         period for  assessment or collection of any Taxes,  which  extension or
         waiver  is  still  in  effect,  and  neither  GPI  nor  any of the  GPI
         Subsidiaries  has entered into any tax allocation or sharing  agreement
         with any other  entity.  GPI has delivered to HRPT correct and complete
         copies of all  examination  reports,  statements  of  deficiencies  and
         similar  documents  prepared by the IRS or any other  taxing  authority
         that  have  been  received  by GPI or any  GPI  Subsidiary.  All  final
         adjustments  made by the IRS with  respect  to any Tax Return of GPI or
         any of the GPI  Subsidiaries  have been reported to the relevant state,
         local, or foreign taxing  authorities to the extent required by law. No
         requests for ruling or determination letters filed by GPI or any of the
         GPI Subsidiaries are pending with any taxing authority. Neither GPI nor
         any GPI  Subsidiary  has any  liability to any Person,  with respect to
         Taxes paid,  owed or to be paid for periods of time during which GPI or
         any  GPI  Subsidiary  or any  predecessor  thereof  were  members  of a
         consolidated  group other than a consolidated group of which GPI is the
         common parent.

                  (c) At all  times  that  it has  been  in  existence,  GPI has
         qualified as a "real estate  investment trust" under Section 856 of the
         Internal  Revenue Code, and each GPI Subsidiary  (other than general or
         limited partnerships or limited liability companies) has qualified as a
         "qualified  REIT  Subsidiary"  under  Section  856(i)  of the  Internal
         Revenue Code. GPI has at all times satisfied  Section  857(a)(3) of the
         Internal  Revenue  Code and does not have any  "non-REIT  earnings  and
         profits" within the meaning of Treasury  Regulation ss.  1.857-11.  The
         assets of GPI as of the Effective Time fulfill the "substantially  all"
         requirement  as it is set forth in IRS  Revenue  Procedure  77-37,  ss.
         3.01.  Neither GPI nor any of the GPI  Subsidiaries has filed a consent
         pursuant to Section  341(f) of the Internal  Revenue Code, or agreed to
         have  Section  341(f)(2)  of the  Internal  Revenue  Code  apply to any
         disposition  of a  subsection  (f) asset (as such  term is  defined  in
         Section  341(f)(4)  of the  Internal  Revenue  Code)  owned  by it.  No
         property of GPI or any of the GPI  Subsidiaries  is property  that such
         entity is or will be required to treat as being owned by another person
         pursuant to the provisions of Section 168(f)(8) of the Internal Revenue
         Code of  1954,  as  amended  and in  effect  immediately  prior  to the
         enactment of the Tax Reform Act of 1986. Neither GPI nor any of the GPI
         Subsidiaries  has  agreed  to or is  required  to make  any  adjustment
         pursuant to Section 481(a) of the Internal  Revenue Code by reason of a
         change  in the  accounting  method  initiated  by GPI or any of the GPI
         Subsidiaries,  and GPI has no  knowledge  that the IRS has proposed any
         such

                                      -20-

<PAGE>


         adjustment or change in accounting  method.  Neither GPI nor any of the
         GPI  Subsidiaries  has  executed  or entered  into a closing  agreement
         pursuant  to  Section  7121  of  the  Internal   Revenue  Code  or  any
         predecessor  provision thereof or any similar provision of state, local
         or foreign law.

         4.17 Contracts.

                  (a) Except as set forth in Disclosure  Schedule 4.17,  neither
         GPI nor any of the GPI  Subsidiaries  is a party to or bound by any (A)

         among  shareholders or granting a right of refusal or for a partnership
         or for a joint  venture or for the  acquisition,  sale or lease  (other
         than the Tenant Leases and Development Property Leases) of any material
         assets of GPI or any of the GPI  Subsidiaries;  (E)  mortgage,  pledge,
         conditional sales contract, security agreement,  factoring agreement or
         other similar  Contract  with respect to any real or tangible  personal
         property  of GPI or any of the GPI  Subsidiaries;  (F) loan  agreement,
         credit agreement, promissory note, guarantee, indenture,  subordination
         agreement,  letter of credit or any other similar type of Contract;  or
         (G)  retainer   Contract  with   attorneys,   accountants,   actuaries,
         appraisers,  investment bankers or other  professional  advisers (other
         than  those  referred  to in  Section  4.28).  GPI and  each of the GPI
         Subsidiaries  has delivered or otherwise  made  available to HRPT true,
         correct  and  complete  copies of the  Contracts  listed in  Disclosure
         Schedule 4.17,  together with all amendments,  waivers,  modifications,
         supplements  or side letters  affecting  the  obligations  of any party
         thereunder.

                  (b) Except as set forth in Disclosure  Schedule  4.17,  GPI is
         not a party to or bound by any employment, consulting, non-competition,
         severance or indemnification  Contract and no GPI Subsidiary is a party
         to or bound by any employment, consulting,  non-competition,  severance
         or indemnification Contract.

         in Disclosure Schedule 4.17:

                           (i) Each of the Contracts which is material to any of
                  GPI or any of the GPI Subsidiaries is valid and enforceable in
                  accordance   with  its  terms,   assuming   the  validity  and
                  enforceability  thereof  against the other parties  thereto in
                  all material respects,  and subject to applicable  bankruptcy,
                  insolvency,   reorganization   and  similar   laws   affecting
                  creditors'  rights and remedies  generally and subject,  as to
                  enforceability, to general principles of equity (regardless of
                  whether enforcement is sought in a proceeding at law or in 
                  equity).

                           (ii)  No  previous  or  current  party  to  any  such
                  Contract  which  is  material  to any of GPI or any of the GPI
                  Subsidiaries  has given to GPI or any of the GPI  Subsidiaries
                  written  notice of or made a claim with  respect to any breach
                  or default under any such Contract which breach or default has
                  not been cured or waived.

         4.18 Insurance.

                  (a)  Schedule  4.18 sets forth a true and correct  list of all
         insurance  policies of any kind or nature whatsoever which are in force
         and to which  GPI or any of the GPI  Subsidiaries  is a named  party or
         beneficiary,  specifying the insurance  carrier,  the type of insurance
         coverage,  the policy number, the date through which premiums have been
         paid,  the  aggregate  amount of  insurance  coverage  per claim or per
         occurrence, as the case may be, applicable self-retention limits and/or
         self- or co-insurance requirements, and describing in reasonable detail
         each pending  claim under each such  policy.  Such  insurance  provides
         coverage  against,  among  other  matters,  property  damage  and other
         casualty loss, personal injury,  workers' compensation claims,  general
         liability,  and other similar risks and matters incident to the conduct
         of the business of GPI and each of the GPI  Subsidiaries  and similarly
         situated businesses and in a manner and in an amount that is consistent
         with industry practice.  GPI and each of the GPI Subsidiaries regularly
         accrues,  and the  financial  statements of GPI reflect the accrual of,
         adequate reserves against loss contingencies,  in accordance with GAAP,
         arising from known and incurred  claims against GPI and each of the GPI
         Subsidiaries.  Based on the past claims  experience  of GPI and each of
         the GPI  Subsidiaries,  such  insurance  together with such reserves is
         reasonably  likely to adequately cover any loss  contingencies  and, to
         GPI's  knowledge,  all  policies  of such  insurance  are  binding  and
         effective upon the issuers (each of whom is reputable and creditworthy)
         in accordance with their respective terms.

                  (b) Neither GPI nor any of the GPI  Subsidiaries  has received
         written notice from any insurance carrier of defects or inadequacies in
         the Premises which,  if  uncorrected,  would result in a termination of
         insurance  coverage  or a material  increase  in the  premiums  charged
         therefor.

         4.19 Bank Accounts.

         Schedule  4.19  contains  a correct  and  complete  list of every  bank
account  or lock box that GPI or any of the GPI  Subsidiaries  has or  maintains
with any bank, savings and loan association or other financial institution,  the
account  identification  number, if any, and the names of persons  authorized to
make withdrawals or have access to each such account or lock box.

         4.20 Accounts.

                  (a)  The  accounts  receivable  of GPI  and  each  of the  GPI
         Subsidiaries as reflected in the Financial  Statements or arising after
         the date  thereof  are the  result  of bona  fide  transactions  in the
         ordinary course of business.

                                      -22-

<PAGE>


                  (b)  All  accounts   payable  of  GPI  and  each  of  the  GPI
         Subsidiaries as reflected in the Financial  Statements or arising after
         the date  thereof  are the  result  of bona  fide  transactions  in the
         ordinary  course of business  and have been paid or are not yet due and
         payable  (giving  due regard to  payment  practices  prevailing  in the
         industry  and  GPI's  and such GPI  Subsidiary's  historical  course of
         dealing with its vendors and suppliers).

         4.21 Labor Matters.

                  (a) No  employees  of GPI or any of the GPI  Subsidiaries  are
         represented by any labor  organization,  and no labor  organization  or
         group of  employees of GPI or any of the GPI  Subsidiaries  have made a
         pending  demand for  recognition  or have  filed a  petition  seeking a
         representation  proceeding  with the  National  Labor  Relations  Board
         within the last two years; and

                  (b) There are no strikes,  grievances or other labor  disputes
         pending  against  GPI  or  any  of the  GPI  Subsidiaries  and,  to the
         knowledge of GPI,  there are no such strikes,  grievances  and disputes
         threatened.  There are no unfair labor  practice  charges or complaints
         pending or, to the knowledge of GPI,  threatened by or on behalf of any
         employee or group of employees of GPI or any of the GPI Subsidiaries.

         4.22 Title to Properties.

                  (a) Schedule 4.22 identifies (i) the real property  comprising
         the  Premises  and the  Development  Properties  which,  as of the date
         hereof,  constitute  all of the real property  owned by GPI and the GPI
         Subsidiaries  (based on surveys and title insurance  policies issued in
         favor of GPI or the GPI Subsidiaries  with respect to such Premises and
         Development  Properties) and (ii) the leases of all real property which
         is  leased  by any of them,  and of the  nature  of  GPI's  and the GPI
         Subsidiaries' interest therein.

                  (b) Except as otherwise set forth in Disclosure Schedule 4.22,
         the  GPI  Subsidiaries  have  marketable  title  to all  real  property
         constituting  the Premises and Development  Properties and title to all
         other property and assets,  tangible and intangible,  owned by them, in
         each case free and clear of all Liens,  except:  (i) the Tenant  Leases
         and Development  Property Leases, (ii) Permitted Liens, and (iii) Liens
         reflected in the Financial Statements.

                  (c) Other  than the  Tenant  Leases,  neither  GPI nor any GPI
         Subsidiary  has entered into any contract or agreement  with respect to
         the occupancy of the Premises and, to GPI's  knowledge,  other than the
         Development Property Leases, there are no contracts or other agreements
         with respect to the occupancy of the Development Properties, which will
         be  binding  after the  Closing.  To GPI's  knowledge,  other  than the
         Contract  Property  Leases,  there is no  contract  or  agreement  with
         respect  to the  occupancy  of the  Contract  Properties  which will be
         binding  after the  Closing  with  respect  thereto.  The copies of the
         Tenant  Leases,  the  Development  Property  Leases  and  the  Contract
         Property Leases heretofore delivered

         as evidenced by amendments  similarly  delivered or made  available and
         constitute the entire agreement between GPI or the GPI Subsidiaries and
         the  tenants  thereunder.  Disclosure  Schedule  4.22  includes a true,

         Lease has asserted in writing or, to GPI's  knowledge,  has any defense

         GPI  Subsidiary  has any material  overdue  outstanding  obligation  to
         provide any tenant under a Tenant Lease with an allowance to construct,
         or to construct at its own expense,  any tenant  improvements;  (iv) no
         tenant under a Tenant Lease is in arrears in the payment of any sums or

         appointment  of or has had  appointed a receiver,  trustee or custodian
         for any of its property; (vi) no tenant under a Tenant Lease or, to the
         knowledge of GPI,  under a Development  Property Lease has requested in

         obligations under its Tenant Lease in any material respect or has given
         written notice  terminating  its Tenant Lease,  or has been released of
         its obligations  thereunder in any material respect prior to the normal
         expiration  of the term  thereof;  (vii) no  guarantor  of any tenant's
         obligations   has  been   released  or   discharged,   voluntarily   or
         involuntarily,  or by operation of law, from any obligation under or in
         connection  with any Tenant Lease or any transaction  related  thereto;

         representations  of the landlords under the Tenant Leases (including in
         any  solicitations  or requests for offers delivered in connection with
         such landlords'  entering into the Tenant Leases) and in any collateral
         documentation  are true and correct in all material  respects as of the
         relevant  date  thereof.  All  covenants  and  agreements  of  the  GPI
         Subsidiaries  as  landlords  under the  Tenant  Leases  required  to be
         performed  as of the date hereof have been  performed  in all  material

                  (e) No Person other than GPI, the GPI Subsidiaries and tenants
         under  Tenant  Leases has any interest in the  Premises,  except as set
         forth in Disclosure Schedule 4.22 or pursuant to Permitted Liens.

         4.23 Proprietary Information.

         GPI and  each  of the  GPI  Subsidiaries  owns,  or has a right  to use
without material limitations or restrictions  adversely affecting the use of the
same in the ordinary  conduct of its business,  subject to all applicable  laws,
rules and  regulations,  including  without  limitation,  directives,  orders or
similar actions of any applicable  state regulatory  authority,  all technology,
know-how, processes and other proprietary information now used in the conduct of
its business  (collectively,  "Proprietary  Data"),  and the consummation of the
transactions  contemplated  by this  Agreement will not alter or impair any such
rights or breach any agreements with third party vendors or require  payments of
additional  sums  thereto.  No claims have been asserted by any person to use or
obtain  access to any such  Proprietary  Data and no person  has  challenged  or
questioned  (i) the  validity  or  effectiveness  of any  license  or  agreement
relating to the same in  accordance  with the terms thereof or (ii) the right of
GPI or any of the GPI Subsidiaries to copy,  modify, use or distribute the same,
nor to the best of GPI's  knowledge,  is there  any  basis  for any such  claim,
challenge  or question.  The manner in which GPI or any of the GPI  Subsidiaries
has  actually  used or copied  such  Proprietary  Data does not  infringe on the
rights of any persons.

                  facilities  and  properties  were owned,  leased,  operated or
                  occupied  by it (or,  to the  knowledge  of GPI,  at any prior

Aggregate  Closing   Consideration  shall  be  reduced  by  $5,000,000  and  all
representations  and warranties  contained in this Agreement shall be deemed not
to include the Houston Premises.  If GPI elects to transfer the Houston Premises

although the Aggregate Closing Consideration shall be reduced as provided in the
next prior sentence,  HRPT shall issue GPI a number of HRPT Common Shares on the
Closing  Date with an  aggregate  value  (based  upon a price for an HRPT Common
Share of $19.2125) equal to such increase in working capital.

with the plans and  specifications  therefor  shall  not have  occurred  and the
obligation  to pay rent of the tenant under the  Development  Property  Lease in
effect  with  respect to the Golden  Premises  shall not have  commenced  by the
Closing  Date,  the  Aggregate  Closing   Consideration   shall  be  reduced  by
$9,046,823.  Upon (x) the 30th day after  substantial  completion  of the Golden

novation of the Development  Property Lease in effect with respect to the Golden
Premises  in favor of an HRPT  Subsidiary,  HRPT will issue GPI a number of HRPT
Common  Shares with an aggregate  value (with each such HRPT Common Share valued
at the  Merger  Price)  equal to  $9,046,823,  less  all  amounts  funded  at or
subsequent to Closing,  exclusive of HRPT Common  Shares  issued at Closing,  or
anticipated  to be funded in  connection  with the punch  list  items by HRPT to

therefor  as set forth in the  related  guaranteed  maximum  price  construction
contract, including, without limitation, any amounts paid to retire indebtedness
or to third party partner, together with interest thereon from the date advanced
by HRPT through the date of issuance of the HRPT Common Shares  pursuant to this
Section  8.3(a) at an annual  rate  equal to 7.4%.  If the  aggregate  amount so
funded,  exclusive of HRPT Common Shares issued at Closing, or so anticipated to
be funded by HRPT (including the interest thereon) exceeds $9,046,823,  one-half
such excess shall be deducted from the Second Closing Consideration.

accordance  with the plans and  specifications  therefor shall not have occurred
and the obligations to pay rent of both tenants under the  Development  Property
Leases in effect with respect to the San Diego Premises shall not have commenced

Premises  in  accordance  with the Plans and  specifications  therefor,  (y) the
transfer to HRPT of the developer partner's interest and (z) the novation of the
Development  Property Leases in effect with respect to the San Diego Premises in
favor of an HRPT Subsidiary,  HRPT will issue GPI a number of HRPT Common Shares
with an  aggregate  value (with each such HRPT Common Share valued at the Merger
Price) equal to $1,530,954  less all amounts  funded or anticipated to be funded
in  connection  with the punch list items by HRPT at or subsequent to Closing to
complete the San Diego Premises in accordance with the plans and  specifications
therefor, including,

                                      -44-

partners,  together with interest thereon from the date advanced by HRPT through

(including the interest thereon) exceeds $1,530,954,  one-half such excess shall
be deducted from the Second Closing Consideration.

                  (c) Aurora Premises. Notwithstanding the provisions of Section
         6.1(d)  or 6.3 on or  before  the  Closing  Date,  GPI will  cause  the
         partnership  interests in Rose Aurora, L.P. held by a GPI Subsidiary to

         Closing  Conditions (as defined below) shall have been satisfied,  HRPT
         will issue GPI a number of HRPT Common  Shares with an aggregate  value
         (with each such HRPT Common Share valued at the Merger  Price) equal to
         $11,647,101  less  the sum of (x)  $1,000,000,  (y) the  amount  of any
         indebtedness or funding obligations assumed by HRPT with respect to the
         Aurora  Premises,  and (z) the  cost to  complete  construction  of the
         Aurora  Premises  in  accordance  with  the  plans  and  specifications
         therefor and as set forth in the guaranteed  maximum price construction
         contract  referred  to below and  including,  without  limitation,  any
         amounts  required  to be paid to buy out the third  party  partner  and
         interest imputed on amounts advanced by HRPT with respect to the Aurora

         rent of the tenant under the  Development  Lease in effect with respect
         to the Aurora Premises shall  commence,  at the  Construction  Rate (as
         defined below),  in  consideration  for the transfer of all GPI and GPI
         affiliate ownership interests in the entity holding title to the Aurora

with  respect  to  the  Aurora  Premises  to an  HRPT  Subsidiary  and  (z)  the
commencement of the obligation of the tenant under the Aurora  Development Lease
to pay rent, HRPT will issue GPI additional HRPT Common Shares with an aggregate
value (with each such HRPT Common Share valued at the Merger Price) equal to the
amount, if any, by which $11,647,101 exceeds the actual aggregate amounts funded
by HRPT  (including  HRPT Common Shares  issued under the next prior  paragraph)
with respect to the Aurora Premises  (including,  without  limitation,  interest
imputed at the Construction Rate and third party buy-out costs.

                  limitation, interest imputed at the Construction Rate, and the
                  cost to buy out the third party partner), which approval shall
                  not  be  unreasonably  withheld,   provided  that  HRPT  shall
                  determine that the Development Lease in effect with respect to
                  the  Aurora  Premises  will,  upon  the  commencement  of  the
                  obligation of the tenant to pay rent thereunder,  provide HRPT
                  with  an  annual  yield  on  the  aggregate   amounts   funded
                  (including,  without  limitation,   interest  imputed  at  the
                  Construction  Rate) with respect to the Aurora Premises of not

         (iv)     HRPT and the tenant under the  Development  Lease with respect
                  to the  Aurora  Premises  shall  have  approved  the  complete
                  construction  drawings  and/or final plans and  specifications

                  withhold, delay or condition its approval).

         (v)      There shall be executed  and  delivered a  guaranteed  maximum
                  price  construction   contract  with  respect  to  the  Aurora

                  provided a completion  bond in form and  substance  reasonably
                  satisfactory to HRPT; and such contractor  shall have obtained

                  party  partner  to  the  Development   Partnership   Agreement
                  relating to the Aurora Premises.

         (viii)   HRPT  shall  reasonably   determine  that  (x)  completion  of
                  construction can occur within the deadlines applicable thereto
                  pursuant to the Aurora  Development  Lease, as the same may be

                  however, that, GPI may, by written notice to HRPT, modify such
                  representations   and   warranties   to  reflect   changes  in
                  circumstances  and HRPT  shall not have the right to object to
                  such  modifications  unless  the  same  shall  materially  and
                  adversely affect the contemplated development or use of Aurora
                  Premises or such Development Partnership.

         As  used  herein,  "Construction  Rate"  shall  mean  (x)  one  hundred
seventy-five  (175)  basis  points in excess of the per annum  rate of  interest
reported in The Wall Street  Journal as the London  Interbank  Offered  Rate for
United  States  dollar  deposits  for a  ninety  (90)  day  term  in the  amount
outstanding  as of the  date of  determination  or (y),  in the  event  the rate
described in clause (x) shall cease to be published,  two (2) percentage  points
in excess of the per annum rate of  interest,  from time to time,  of the 14-day
moving average closing trading price of the 180-day Treasury Bills.

                  (d)  Liquidation.  If any payments due GPI under  Sections 8.3
         (a), (b) or (c) become payable after GPI has  liquidated,  the payments
         shall be made to the Second Closing Recipient.

                  (e) Fractional  Shares.  If the Second Closing Recipient would
         receive a fraction of a HRPT Common Share  pursuant to Section  8.3(a),
         (b) or (c), a check  representing  an amount  determined by multiplying
         such  fractional  share by the Merger  Price shall be  delivered to the
         Second Closing Recipient.

                  (f) Control.  Notwithstanding  6.1(d), HRPT will permit GPI to
         control  negotiations  with the  developer  partners'  and  others  and
         supervision of  construction  in connection with any of the Development
         Properties  which are not completed on or before the Closing Date until
         July 31, 1997,  provided any  modification  or amendment of  agreements
         relating  thereto will be subject to the  reasonable  approval of HRPT.
         After  July  31,  1997,  HRPT  will  control   negotiations   with  the
         development  partners'  and others  and  supervision  of  construction,
         provided that any modification or amendment of any agreements  relating
         thereto will be subject to the reasonable  approval of GPI. In the case
         of HRPT's refusal to give  approval,  if the proposed  modification  or
         amendment  would have an adverse  effect on HRPT's  expected yield with
         respect to the particular  Development Property HRPT's refusal shall be
         deemed  reasonable.  In the case of GPI's refusal to give approval,  if
         the proposed  modification or amendment would have an adverse effect on
         GPI's  expected  profit  with  respect  to the  particular  Development
         Property,  GPI's  refusal  shall be deemed  reasonable.  HRPT agrees to
         comply  in all  material  respects  with the  terms of the  Development
         Partnership Agreements.

         Common Shares as  calculated  above  promptly  upon receipt  thereof or
         shall assign the rights of Rosecliff  Realty  Funding,  Inc. to receive

         Purchase  and  Sale of Real  Property  and  Escrow  Instructions  dated
         October 4,1996 (the "LA MEPS Agreement") prior to the Closing Date, the

         Common Shares with an aggregate value (with each such HRPT Common Share
         valued at the Merger  Price)  equal to  $10,060,162,  less the costs of
         acquisition  (net of any deposit)  including  closing costs.  If the LA
         MEPS  Premises are not acquired by the Second  Closing Date, or at such
         earlier time as the LA MEPS Agreement is terminated, HRPT shall pay GPI
         an amount  equal to the  deposit  under the LA MEPS  Agreement  in HRPT

         Aggregate  Closing  Consideration  shall be reduced by $12,159,106.  At
         such time as the Phoenix  Premises are acquired in accordance  with the
         terms of the Phoenix  Agreement,  HRPT shall issue GPI a number of HRPT
         Common Shares with an aggregate value (with each such HRPT Common Share

         any increase in the purchase price for the Phoenix Premises pursuant to
         any  amendment  to the  Phoenix  Agreement  to which  HRPT  shall  have
         consented in writing less the costs of acquisition (net of any deposit)
         including  closing costs.  If the Phoenix  Premises are not acquired by

                  (d)  Liquidation.  If any payments due GPI under  Sections 8.4
         (a), (b) or (c) become payable after GPI has  liquidated,  the payments
         shall be made to the Second Closing Recipient.

                  (e) Fractional  Shares.  If the Second Closing Recipient would
         receive a fraction of a HRPT Common Share  pursuant to Section  8.4(a),
         (b) or (c), a check  representing  an amount  determined by multiplying
         such  fractional  share by the Merger  Price shall be  delivered to the
         Second Closing Recipient.

                  (f) Control.  Notwithstanding the Closing, if HRPT will permit

         the  Closing  Date  until July 31,  1997,  provided  any  modification,
         amendment or termination of agreements relating thereto will be subject
         to the  reasonable  approval of HRPT.  After July 31,  1997,  HRPT will
         control  negotiations  with the sellers and others,  provided  that any
         modification  or amendment of any agreements  relating  thereto will be
         subject  to the  reasonable  approval  of GPI.  In the  case of  HRPT's
         refusal to give approval,  if the proposed  modification,  amendment or
         termination  would have an adverse effect on HRPT's expected yield with
         respect to the  particular  Contract  Property  HRPT's refusal shall be
         deemed  reasonable.  In the case of GPI's refusal to give approval,  if
         the proposed  modification or amendment would have an adverse effect on
         GPI's expected profit with respect to the particular  Contract Property
         GPI's refusal shall be deemed reasonable.  HRPT agrees to comply in all
         material  respects  with the terms of the purchase and sale  agreements
         relating to the Contract Properties.

         8.5 College Park.

in the Indemnification  Agreement) for which the Indemnified Parties (as defined
in the Indemnification Agreement) shall be entitled to indemnification under the
Indemnification  Agreement,  without  regard to any minimum loss  threshold  and

warranty.

negotiations  with the Sellers named in the Purchase  Agreement  with respect to
the matters  contemplated  by Section 2.B and 2.C of the Purchase  Agreement and
HRP  shall  give GPI  notice of any  information  obtained  by HRP with  respect
thereto.

any of them (provided with respect to the GPI  Subsidiaries  the obligation will
be only with respect to periods  ending on or before the  Effective  Time),  and
provide  HRPT,  at its  request,  with  copies  for HRPT's  review,  of all such
returns, reports, filings and amendments at GPI's offices prior to filing.

         If at any time prior to the Closing Date HRPT shall  determine  that it
requires the consent of its lenders to permit the  transactions  contemplated by
this  Agreement to be  consummated as a merger between Merger Sub and GPH and if
HRPT shall not have  obtained  such  consent,  HRPT may fulfill its  obligations
under this  Agreement by causing an HRPT  Subsidiary  to purchase the GPH Common
Shares  for  the  Aggregate   Closing   Consideration  and  the  Second  Closing
Consideration  on the terms and  conditions  set forth in this Agreement and the
parties agree to make such conforming changes as may be reasonably required as a
result thereof.

expenses incurred by GPI or its successor for such period or (ii) $947,935, then
the excess,  if any, of the amount described in clause (b) above over the amount

equal to the sum of all  pending  claims,  shall be  deposited  with a  mutually
acceptable  escrow agent to be held pursuant to the terms of an escrow agreement
substantially in the form of Schedule 9.2.


                                   SECTION 10

         the trustees of HRPT;

                  (b) by either HRPT or GPI, in writing,  without liability,  if

         that no party  shall have the right to  terminate  under  this  Section
         10.1(b) if the conditions precedent to such Party's obligation to close
         have been or at Closing  would be satisfied or have been waived by such
         Party and such Party has nonetheless failed or refused to close;

                  (c) by either HRPT or GPI in writing,  without  liability,  if
         there shall be any order,  writ,  injunction  or decree of any court or
         governmental  or regulatory  agency  binding on HRPT and/or GPI,  which
         prohibits  or  restrains   HRPT  and/or  GPI  from   consummating   the
         transactions contemplated by this Agreement, provided that HRPT and GPI
         shall  have used  their  best  efforts  to have any such  order,  writ,
         injunction  or decree  lifted and the same  shall not have been  lifted
         within  90 days  after  entry,  by any such  court or  governmental  or

                  7.2 shall not have been  complied  with or performed  and such
                  noncompliance or  nonperformance  shall not have been cured or
                  eliminated (or by its nature cannot be cured or eliminated) by

                           (ii)  if  HRPT  shall  (i)  fail  to  perform  in any
                  material  respect its  agreements  contained in this Agreement
                  required  to be  performed  by it on or prior  to the  Closing
                  Date, or (ii) breach any of its  representations or warranties
                  contained in this  Agreement,  which  failure or breach is not

                  intent to terminate  this  Agreement  pursuant to this Section
                  10.1(d)(ii);

                  (e)  by HRPT, in writing, without liability:

                           (i) if the  conditions  set forth in Sections 7.1 and
                  7.3 shall not have been  complied  with or performed  and such
                  noncompliance or  nonperformance  shall not have been cured or
                  eliminated (or by its nature cannot be cured or eliminated) by
                  GPI or otherwise by March 31, 1997; or

                           (ii) if GPI shall (i) fail to perform in any material
                  respect its agreements contained in this Agreement required to
                  be performed on or prior to the Closing  Date,  or (ii) breach
                  any of its  representations  or  warranties  contained in this
                  Agreement,  which  failure  or breach is not cured  within ten

                  this Agreement pursuant to this Section 10.1(e)(ii);

                  provided  if GPI shall  breach a  representation  or  warranty
                  which  would  have a  Material  Adverse  Effect as  defined in
                  Section 1.59(ii),  HRPT shall not terminate this Agreement and
                  shall  consummate the transactions on the Closing Date without
                  adjustment to the Aggregate  Closing  Consideration on account
                  of  such   breach   and   shall   have   recourse   under  the
                  Indemnification Agreement, it being agreed that HRPT's failure
                  to exercise its right to terminate this Agreement shall not be
                  deemed a waiver of such breach.

         10.2 Extension.

                  (a) Notwithstanding  anything contained in Section 10.1 to the
         contrary,  if GPI shall be unable to satisfy a closing  condition prior
         to March 31,  1997,  GPI shall have the right to delay the Closing Date
         and extend the date for  termination  of the rights and  obligations of
         the parties under Section 10.1 until the date which is 10 business days
         following  notice from GPI to HRPT that such closing  condition(s)  are
         satisfied but not later than May 31, 1997.

         confirmed  as  provided  in  the   definition   of  Aggregate   Closing
         Consideration.

The  failure  of any Party at any time or times to  require  performance  of any
provisions of this Agreement  shall in no manner affect the right to enforce the
same.  No waiver by any Party of any  conditions,  or of the breach of any term,
provision,  warranty,  representation,  agreement or covenant  contained in this
Agreement,  whether by conduct or otherwise,  in any one or more instances shall

or breach of any other term, provision, warranty,  representation,  agreement or
covenant contained in this Agreement.

         11.11 Severability.

         Any provision of this Agreement which is prohibited or unenforceable in
any jurisdiction will, as to such jurisdiction,  be ineffective to the extent of
such  prohibition  or  unenforceability   without   invalidating  the  remaining
provisions of this Agreement,  and any such prohibition or  unenforceability  in
any jurisdiction will not invalidate or render  unenforceable  such provision in
any other  jurisdiction.  To the extent  permitted by law, the Parties waive any
provision of law which renders any such provision prohibited or unenforceable in
any respect.

         11.12 Counterparts.

         This  Agreement  may be executed in two or more  counterparts,  each of
which shall be deemed an original, and it shall not be necessary in making proof
of this  Agreement or the terms of this Agreement to produce or account for more
than one of such counterparts.

         The  Declaration  of Trust of HRPT, a copy of which has been duly filed
with the  Department  of  Assessments  and  Taxation  of the State of  Maryland,
provides that the name "Health and  Retirement  Properties  Trust" refers to the
trustees  under such  Declaration  of Trust  collectively  as trustees,  but not
individually or personally, and that no trustee, officer, shareholder,  employee
or agent of HRPT shall be held to any personal liability,  jointly or severally,
for any obligation of, or claim against,  HRPT. All persons dealing with HRPT in
any way shall look only to the assets of HRPT, respectively,  for the payment of
any sum or the performance of any obligation.

         11.14 Diligence.

         HRPT acknowledges that it has received surveys (other than with respect
to the Premises located in Richland, Washington) and title insurance commitments
and/or policies with respect to all of the Premises.

                                ESCROW AGREEMENT


         THIS ESCROW AGREEMENT (this "Escrow  Agreement") is made as of February
__,  1997  by  and  among  Health  and  Retirement  Properties  Trust  ("HRPT"),
Government Property Investors, Inc.
("GPI"), and ____________________  (the "Escrow Agent").

                                 R E C I T A L:

         HRPT  and  GPI  have  entered  into a  Merger  Agreement  (the  "Merger
Agreement"),  an executed  copy of which has been  provided to the Escrow Agent,
pursuant to which Government Property Holdings Trust ("GPH") will be merged with
and into HUB  Acquisition  Trust  ("Merger Sub") on the terms and conditions set
forth in the Merger Agreement.

         Pursuant to the Merger Agreement, HRPT has agreed to deposit $5,000,000
into escrow upon  execution  of this Escrow  Agreement  subject to the terms and
conditions set forth in the Merger Agreement and in this Escrow Agreement.

         NOW, THEREFORE, the parties agree as follows:

         Section 1. Defined Terms. Terms not otherwise defined herein shall have
the  respective  meanings  prescribed  therefor  in the  Merger  Agreement.  The
following terms are defined in this Escrow Agreement:

         "Bank" is _______________.

         "Escrow Fund" is defined in Section 3 of this Escrow Agreement.

         Section 2. Appointment of Escrow Agent. HRPT and GPI hereby appoint the
Escrow Agent as the escrow agent to hold the Escrow Fund in accordance  with the
terms and conditions of this Escrow Agreement.

         Section  3.  Delivery  and  Receipt of Funds.  Simultaneously  with the
execution of this Escrow  Agreement,  HRPT shall deliver to the Escrow Agent the
sum of $5,000,000 in immediately  available  funds by wire transfer.  The Escrow
Agent shall open an escrow  account in the name of HRPT and shall  deposit  into
such  account  such  immediately  available  funds.  The  amount  so  deposited,
including accrued interest thereon, is referred to as the "Escrow Fund." Receipt
of the Escrow Fund from HRPT is hereby acknowledged by the Escrow Agent.

         Section 4. Investment of Escrow Fund. Until distributed and released in
accordance  with the terms and conditions of this Escrow  Agreement,  the Escrow
Agent shall invest the Escrow Fund in a so-called  "money  market"  deposit fund
with the Bank or in such other  liquid,  investment  grade  securities as may be
specified  in writing by HRPT.  The Escrow  Fund may be  invested in the name of
Escrow Agent and may be commingled with other funds.

         Section 5.  Release of Escrow Fund.  The Escrow Agent shall  distribute
and release the Escrow Fund ten days after  receipt of notice (a) from HRPT that
either there has been compliance with the conditions set forth in Section 7.2 of
the Merger Agreement or that the Merger  Agreement has been terminated  pursuant
to Section 10.1(a), (b), (c) or (e) thereof and that any applicable grace period
has  expired  or (b)  from  GPI that GPI has  terminated  the  Merger  Agreement
pursuant to Section 10.1(d)(ii) thereof and that any applicable grace period has
expired.  Such notice shall contain a certification  by the party delivering the
notice certifying that such distribution and release is being requested pursuant
to clause (a) or clause (b) of the preceding sentence, as applicable, and


<PAGE>


                                       -2-

that a copy of such notice has been  concurrently sent to HRPT (in the case of a
notice by GPI) or to GPI (in the case of a notice by HRPT) and shall specify the
name and address of the party to whom such Escrow  Fund shall be  delivered  and
wire  transfer  information.  Within  ten days  after  receipt  of such  notice,
provided  that the Escrow Agent shall not have  received a contrary  instruction
from the other  party,  the Escrow  Agent  shall  deliver the Escrow Fund to the
party  so  specified.   If  the  Escrow  Agent  has  received  such  a  contrary
instruction, it shall release the Escrow Fund only pursuant to a joint direction
in writing of HRPT and GPI or pursuant to the decision of an arbitrator pursuant
to the arbitration  proceedings set forth in Section 13 of this Agreement.  Upon
distribution  and release of the Escrow  Fund,  this Escrow  Agreement  shall be
deemed terminated and the Escrow Agent shall be released and discharged from all
further obligations hereunder.

         Section 6. Duties of Escrow Agent.  The  acceptance by the Escrow Agent
of its duties as such under this Escrow  Agreement  is subject to the  following
terms and  conditions,  which HRPT and GPI hereby agree shall govern and control
with respect to the rights,  duties,  liabilities  and  immunities of the Escrow
Agent:

                  (a) The Escrow Agent acts hereunder as a depositary  only, and
is not  responsible  or liable in any manner  whatever for any  investment  made
pursuant to the provisions of Section 4 or any failure,  refusal or inability of
the Bank to release or make payment pursuant to the Escrow Agent's  direction of
said Escrow Fund, including by reason of insolvency or bankruptcy of the Bank.

                  (b) The Escrow  Agent  shall not be liable for acting upon any
written  notice,  request,  waiver,  consent,  receipt  or other  instrument  or
document which the Escrow Agent in good faith believes to be genuine and what it
purports to be.

                  (c) It is understood  and agreed that the duties of the Escrow
Agent hereunder are purely ministerial in nature and that it shall not be liable
for any error of  judgment,  fact or law, or any act done or omitted to be done,
except for its own willful  misconduct,  breach of fiduciary  duty, bad faith or
gross negligence or that of its officers,  directors,  employees and agents. The
Escrow Agent's  determination  as to whether an event or condition has occurred,
or been met or satisfied,  or as to whether a provision of this Escrow Agreement
has been  complied  with, or as to whether  sufficient  evidence of the event or
condition or compliance  with the provision has been  furnished to it, shall not
subject the Escrow Agent to any claim, liability or obligation whatsoever,  even
if it shall  be found  that  such  determination  was  improper  and  incorrect,
provided, only, that the Escrow Agent and its officers, directors, employees and
agents  shall not have been guilty of willful  misconduct,  breach of  fiduciary
duty, bad faith or gross negligence in making such determination.

                  (d) The Escrow Agent may consult with, and obtain advice from,
legal counsel including its own officers, employees and partners in the event of
any dispute or question as to the  construction of any of the provisions  hereof
or its duties  hereunder,  and it shall  incur no  liability  and shall be fully
protected  in  acting  in  good  faith  in  accordance   with  the  opinion  and
instructions of such counsel.

                  (e) In the  event  of any  disagreement  or lack of  agreement
between HRPT and GPI of which the Escrow Agent has knowledge, resulting or which
might result in adverse  claims or demands with respect to the Escrow Fund,  the
Escrow Agent shall be entitled, in its sole discretion, to refuse to comply with
any claims or demands on it with  respect  thereto  until such  matter  shall be
resolved,  and in so refusing, the Escrow Agent may elect to make no delivery or
other disposition of the Escrow Fund, and in so doing the Escrow Agent shall not
be or become  liable in any way to either HRPT or GPI for its failure or refusal
to comply with such  claims or demands,  and it shall be entitled to continue so
to  refrain  from  acting,  and so to  refuse to act,  until all such  claims or
demands  (i)  shall  have  been  finally  determined  by a  court  of  competent
jurisdiction, or (ii) shall have


<PAGE>


                                       -3-

been  resolved by the  agreement of HRPT and GPI and the Escrow Agent shall have
been notified thereof in writing.

                  (f) The Escrow  Agent may  resign at any time upon  giving ten
(10)  days'  notice to HRPT and GPI and may  appoint a  successor  escrow  agent
hereunder  so long as such  successor  shall accept and agree to be bound by the
terms of this Escrow  Agreement  and shall be  acceptable to HRPT and GPI. It is
understood and agreed that the Escrow Agent's resignation shall not be effective
until a successor  escrow  agent  agrees to be bound by the terms of this Escrow
Agreement.

         Section 7. No  Representations  by Escrow Agent. The Escrow Agent makes
no  representation  as to the validity,  value,  genuineness,  negotiability  or
collectibility  of any  security  or other  document  or  instrument  held by or
delivered to or by it.

         Section 8. Obligations of Escrow Agent. The Escrow Agent shall be under
no obligation to institute or defend any actions,  suits or legal proceedings in
connection  herewith  or take any other  action  likely to involve it in expense
unless first indemnified to its reasonable satisfaction.

         Section 9. Expenses. The reasonable  out-of-pocket expenses (including,
without  limitation,  reasonable legal fees and  disbursements)  incurred by the
Escrow Agent in the  performance  of its duties  hereunder  shall be  reimbursed
one-half  by GPI and  one-half by HRPT.  Such  reimbursement  for  out-of-pocket
expenses  shall be made by cash  payment to the  Escrow  Agent from time to time
upon its  written  request.  The Escrow  Agent  shall have no right or lien with
respect to the Escrow Fund for  payment of such  expenses.  Except as  otherwise
herein  or in the  Merger  Agreement  provided,  each  party  shall  pay its own
expenses  incident to the  performance or enforcement of this Escrow  Agreement,
including  all fees and  expenses  of its  counsel  for all  activities  of such
counsel undertaken pursuant to this Escrow Agreement.

         [Section 10. Escrow Agent Status.  _____ hereby  acknowledges  that the
Escrow Agent is counsel to _____ and agrees that it will not seek to  disqualify
the Escrow  Agent from acting and  continuing  to act as counsel to _____ in the
event of a dispute  hereunder or in the course of the defense or  prosecution of
any claim  relating  to the  transactions  contemplated  hereby or by the Merger
Agreement;  provided,  however, that in the event of a dispute, the Escrow Agent
shall (a) immediately seek to appoint a successor  escrow agent,  which shall be
acceptable to HRPT and GPI,  having no business  relationships  with HRPT or GPI
and (b) immediately  resign upon acceptance of such appointment and agreement to
be bound by the terms of this Escrow Agreement by such successor escrow agent.]

         Section 11. Assignment;  Successors and Assigns.  This Escrow Agreement
shall not be assignable by either party without the prior written consent of the
other.

         Nothing in this Escrow Agreement expressed or implied is intended to or
shall be  construed  to  confer  upon or create in any  Person  (other  than the

remedies under or by reason of this Agreement,  including without limitation any
rights to enforce this Escrow Agreement.

         Section 12. Specific Performance; Other Rights and Remedies. Each party

Agreement,  be  entitled  to  injunctive  relief and to enforce its rights by an
action for specific  performance to the extent permitted by applicable law. Each
party hereby waives any  requirement  for security or the posting of any bond or
other surety in connection  with any temporary or permanent award of injunctive,
mandatory or other equitable relief. Nothing herein contained shall

                  INVESTMENT AND REGISTRATION RIGHTS AGREEMENT


         THIS INVESTMENT AND REGISTRATION  RIGHTS AGREEMENT (the "Agreement") is
made and entered  ____________,  1997,  among Health and  Retirement  Properties
Trust, a Maryland real estate investment trust ("HRPT"), and Government Property
Investors, Inc., a Delaware corporation (including its successors and assignees,
the "Holder").

                                    RECITALS

         A. Concurrently  with the execution of this Agreement,  HRPT has issued
to the Holder _____ shares of the  beneficial  interest $.01 par value per share
of HRPT ("Initial  Shares") and from time to time will issue  additional  shares
("Additional  Shares"  and  together  with  the  Initial  Shares  and any  other
securities  which are hereafter  issued with respect thereto by way of exchange,
reclassification,  dividend or distribution, whether or not such securities have
been sold to the public, the "Securities") pursuant to a Merger Agreement, dated
February 17, 1997 (the "Merger Agreement"), among HRPT and the Holder.


         B. The Securities  have been issued to the Holder without  registration
under the Securities Act of 1933, as amended (the  "Securities  Act"),  and HRPT
and the Holder desire to provide for compliance  with the Securities Act and for
the  registration  of the  Securities  upon the terms and  conditions  set forth
below.

         NOW, THEREFORE, the parties agree as follows:

         1. Certain Other Definitions.  Capitalized terms used but not otherwise
defined in this  Agreement  shall have the meanings given therefor in the Merger
Agreement.  The  capitalized  terms set forth  below  shall  have the  following
meanings:

              1.1  "Commission":  the  United  States  Securities  and  Exchange
Commission and any successor federal agency having similar powers.

              1.2 The terms "register", "registered" and "registration" refer to
a  registration  effected by preparing  and filing a  registration  statement in
compliance  with the  Securities  Act,  and the  declaration  or ordering of the
effectiveness of such registration statement.

              1.3 "Registrable  Securities":  Securities that have not been sold
pursuant to a registration statement or under Rule 144 under the Securities Act.

              1.4  "Registration  Expenses":  all  expenses  incurred by HRPT in
complying with Section 5, including,  without  limitation,  all registration and
filing fees, printing expenses, fees and disbursements of counsel for HRPT, blue
sky fees and expenses, and accountants' expenses including,  without limitation,
any  special  audits or comfort  letters  incident  to or  required  by any such
registration,  transfer taxes, fees of transfer agents and registrars,  costs of
insurance,   but  excluding  any  fees  and   disbursements   of   underwriters,
underwriting  discounts and  commissions and expenses of Holder and, in the case
of an underwriter offering pursuant to Section 5.2(j) any filing fees.

         2.  Representations  and  Warranties of HRPT. The  representations  and
warranties  of  HRPT  contained  in  Section  5  of  the  Merger  Agreement  are
incorporated by reference into this Agreement. The Holder is entitled to rely on
such representations and warranties as if they were set forth in this Agreement.
The Holder  agrees  that it shall not bring any action  based on a breach of any
such

                                                           

<PAGE>



representation  and warranty against HRPT, any Subsidiary,  any affiliate or any
officer,  director,  employee or agent of any of them with  respect to any claim
made after the first anniversary of the date of this Agreement.

         3.  Representations  and Warranties of Holder.  GPI hereby  represents,
acknowledges,  covenants  and agrees as follows:  (i) the  Securities  are being
acquired  for  its  own  account  for  investment  and  not  with a view  to any
distribution  or public offering within the meaning of the Securities Act or any
state  securities law; (ii) the Securities  have not been  registered  under the
Securities Act or any state securities law; (iii) it is an "accredited investor"
within the meaning of Rule 501  promulgated  by the  Commission  pursuant to the
Securities  Act;  and  (iv) it will not sell or  otherwise  transfer  any of the
Securities  except upon the terms and  conditions  specified  herein and it will
cause  any  subsequent  Holder of the  Securities  to agree to take and hold the
Securities subject to the terms and conditions of this Agreement,  provided that
any Holder  may sell the  Securities  in one or more  private  transactions  not
requiring registration under the Securities Act or any state securities law.

         4.  Restrictions on Transfer.

              4.1 Legend. Each certificate representing the Securities issued to
the Holder or to a  subsequent  Holder  pursuant to Section 4.2 shall  include a
legend in substantially the following form,  provided that such legend shall not
be required if such  transfer  is being made in  connection  with a sale that is
exempt from registration pursuant to Rule 144 under the Securities Act or if the
opinion of counsel  referred  to in Section  4.3 is to the  further  effect that
neither  such legend nor the  restrictions  on  transfer  in this  Section 4 are
required in order to ensure compliance with the Securities Act:

         THE SHARES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN  REGISTERED
         UNDER THE  SECURITIES  ACT OF 1933 OR ANY STATE  SECURITIES ACT AND MAY
         NOT BE SOLD OR  TRANSFERRED IN THE ABSENCE OF SUCH  REGISTRATION  OR AN
         EXEMPTION THEREFROM.  SUCH SHARES MAY BE TRANSFERRED ONLY IN COMPLIANCE
         WITH THE CONDITIONS SPECIFIED IN THE INVESTMENT AND REGISTRATION RIGHTS
         AGREEMENT  DATED AS OF  __________,  1997,  BETWEEN  THE ISSUER AND THE
         OTHER ENTITIES  NAMED THEREIN,  A COMPLETE AND CORRECT COPY OF WHICH IS
         AVAILABLE FOR INSPECTION AT THE PRINCIPAL OFFICE OF THE ISSUER AND WILL
         BE  FURNISHED  TO THE HOLDER  HEREOF UPON  WRITTEN  REQUEST AND WITHOUT
         CHARGE.

              4.2 Notice of Transfer. Prior to any proposed assignment, transfer
or sale of any Securities  (other than pursuant to a  Registration  Statement or
pursuant  to Rule  144(k)),  the Holder of such  Securities  shall give  written
notice to HRPT of  Holder's  intention  to effect such  assignment,  transfer or
sale,  which  notice  shall  set  forth  the date of such  proposed  assignment,
transfer  or  sale.  Holder  shall  also  furnish  to HRPT an  agreement  by the
transferee  that it is taking  and  holding  the same  subject  to the terms and
conditions  specified  in this  Agreement  and a  written  opinion  of  Holder's
counsel,  in form  reasonably  satisfactory  to  HRPT,  to the  effect  that the
proposed transfer may be effected without registration under the Securities Act.

              4.3 Termination of  Restrictions.  The  restrictions  set forth in
this Section 4 shall  terminate and cease to be effective with respect to any of
the  Securities  (i)  upon  the  sale of any  such  Securities  which  has  been
registered  under the Securities Act, (ii) upon receipt by HRPT of an opinion of
counsel, in form reasonably  satisfactory to HRPT, to the effect that compliance
with such  restrictions  is not necessary in order to comply with the Securities
Act with respect to the sale of the  Securities or (iii) upon the  expiration of
the three-year  period  referred to in Rule 144(k)  promulgated  pursuant to the
Securities  Act (or such  other  period  set  forth in Rule  144(k) as it may be
amended from time to time).  Whenever such restrictions shall so terminate,  the
Holder shall be entitled to receive from HRPT, without

                                        2

<PAGE>



expense  (other  than  transfer  taxes,  if any,  if the  Holder  requests  that
certificates  be issued in another name),  certificates  for such Securities not
bearing the legend set forth in Section 4.1.

         5. Registration under Securities Act  etc.

              5.1 Shelf-Registration.

                  (a) General.  HRPT shall prepare and file with the  Commission
         on or prior to 30 days after the date hereof, a registration  statement
         on an appropriate  form under the Act relating to the offer and sale of
         the Initial Shares (and with respect to the Additional  Shares, as soon
         after their issuance as is reasonably  practicable,  HRPT shall prepare
         and file appropriate  amendments relating to such shares) by the Holder
         in  accordance  with the  methods  of  distribution  set  forth in such
         registration statement and Rule 415 under the Act (hereafter,  a "Shelf
         Registration  Statement")  and shall use its best  efforts to cause the
         Shelf  Registration  Statement  to be  declared  effective  as  soon as
         reasonably practicable thereafter.

                  (b) Effective  Period.  HRPT agrees to use its best efforts to
         keep the Shelf Registration  Statement  continuously effective in order
         to permit the prospectus  included in the Shelf Registration  Statement
         to be  usable  by the  Holders  for a period  of three  years  from the
         Closing Date or such shorter  period that shall  terminate when all the
         Securities covered by the Shelf Registration  Statement have been sold;
         provided that HRPT shall be deemed not to have used its best efforts to
         keep the Shelf  Registration  Statement  effective during the requisite
         period if it voluntarily  takes any action that would result in holders
         of the Securities covered by the Shelf Registration Statement not being
         able to offer and sell such Securities during that period,  unless such
         action is required by applicable law, and provided,  further,  that the
         foregoing  shall not apply to  actions  taken by HRPT in good faith and
         for  valid  business   reasons  (not  including   avoidance  of  HRPT's
         obligations pursuant to this Agreement), including, without limitation,
         the acquisition or divestiture of a material portion of its assets, the
         offering of Securities  pursuant to the registration  rights granted to
         others or the offering of  Securities  by HRPT for its own account,  so
         long as HRPT promptly complies with the requirements of Section 5.2(f),
         if  applicable.  Any such  period  during  which HRPT fails to keep the
         Shelf Registration  Statement effective and usable for offers and sales
         of Securities  is hereafter  referred to as a  "Suspension  Period".  A
         Suspension  Period shall commence on and include the date on which HRPT
         provides  notice  that the Shelf  Registration  Statement  is no longer
         effective  that  the  prospectus  included  in the  Shelf  Registration
         Statement  is no longer  usable for offers and sales of  Securities  or
         that HRPT is required to suspend the sale of Securities  because of the
         occurrence of an  underwritten  offering in connection  with the demand
         registrations or primary registrations  referred to above and shall end
         on the date  when  each  seller  of  Securities  covered  by the  Shelf
         Registration  Statement  either receives the copies of the supplemented
         or amended  prospectus  contemplated by Section 5.2(f) or is advised in
         writing by HRPT that use of the prospectus may be resumed;  provided no
         one  Suspension  Period shall continue for more than 75 days. If one or
         more Suspension  Periods occur, the time period  referenced above shall
         be extended by a period which is not less than the aggregate  number of
         days included in all Suspension Periods.

                  (c) Block-out  Period.  Each Holder of Registrable  Securities
         agrees by acquisition of such Registrable  Securities,  if so requested
         by HRPT,  not to effect any sale of  Securities  pursuant  to the Shelf
         Registration  Statement  for any  period  (but not  more  than 75 days)
         reasonably  deemed  necessary  by HRPT or its managing  underwriter  in
         connection with the offering of HRPT equity pursuant to an underwritten
         offering  pursuant  to demand  registration  rights  granted to another
         entity  pursuant  to Section 11 or the  offering  of any debt or equity
         securities by HRPT for its own account (a "Block-out Period").

<PAGE>



                  (d)    Anything   in   this    Agreement   to   the   contrary
         notwithstanding,  in any period of 12 consecutive months, the aggregate
         time during which Holder would be  prohibited  from selling  Securities
         pursuant  to the Shelf  Registration  Statement  during any  Suspension
         Periods and Block- out Periods shall not exceed 150 days.

              5.2 Registration Procedures. HRPT shall:

                  (a) cause any registration statement filed pursuant to Section
         5.1 and the related  prospectus and any amendment or supplement,  as of
         the  effective  date  of  such  registration  statement,  amendment  or
         supplement,  (i) to comply in all material respects with the applicable
         requirements of the Securities Act and the rules and regulations of the
         Commission promulgated under the Securities Act and (ii) not to contain
         any untrue  statement  of a  material  fact or omit to state a material
         fact required to be stated  therein or necessary to make the statements
         therein not misleading;

                  (b) prepare and file with the Commission  such  amendments and
         supplements to such  registration  statement and the prospectus used in
         connection with such registration statement as may be necessary to keep
         such registration statement effective and to comply with the provisions
         of  the  Securities  Act  with  respect  to  the   disposition  of  all
         Registrable   Securities   and  other   securities   covered   by  such
         registration  statement  until  the  earlier  of such  time as all such
         Registrable   Securities  and  securities  have  been  disposed  of  in
         accordance  with the intended  methods of  disposition by the seller or
         sellers  thereof  set  forth in such  registration  statement  or for a
         period of three years from the Closing  Date;  and will  furnish,  upon
         request, to each such seller and each Holder a copy of any amendment or
         supplement to such registration statement or prospectus prior to filing
         it and shall not file any such  amendment  or  supplement  to which any
         such  seller or Holder  shall have  reasonably  objected on the grounds
         that such  amendment  or  supplement  does not  comply in all  material
         respects with the requirements of the Securities Act or of the rules or
         regulations thereunder;

                  (c) furnish to each seller of such Registrable  Securities and
         each  Holder  such  number of  conformed  copies  of such  registration
         statement and of each such  amendment and  supplement  thereto (in each
         case including all  exhibits),  such number of copies of the prospectus
         included in such  registration  statement  (including each  preliminary
         prospectus  and  any  summary  prospectus),   in  conformity  with  the
         requirements   of  the  Securities   Act,  such   documents,   if  any,
         incorporated by reference in such registration statement or prospectus,
         and such  other  documents,  as such  seller or Holder  may  reasonably
         request;

                  (d)  use  its  best   efforts  to   register  or  qualify  all
         Registrable   Securities   and  other   securities   covered   by  such
         registration  statement under such other securities or blue sky laws of
         the  states  of the  United  States  as each  seller  or  Holder  shall
         reasonably  request,  to keep such  registration  or  qualification  in
         effect for so long as such  registration  statement  remains in effect,
         and do any and all other  acts and  things  which may be  necessary  or
         advisable to enable such seller to consummate  the  disposition in such
         jurisdictions   of  its   Registrable   Securities   covered   by  such
         registration statement, except that HRPT shall not for any such purpose
         be  required  to  qualify   generally  to  do  business  as  a  foreign
         corporation in any  jurisdiction  in which it is not and would not, but
         for the  requirements  of this  Section  5.2(d),  be obligated to be so
         qualified,  or to subject itself to taxation in any such  jurisdiction,
         or to consent to general service of process in any such jurisdiction;

                  (e)  upon  request,  furnish  to each  seller  of  Registrable
         Securities  and each  Holder a signed  counterpart,  addressed  to such
         seller and such  Holder,  of (i) an opinion of counsel for HRPT,  dated
         the effective date of such registration statement,  and (ii) a "comfort
         letter", signed

                                        4

         by  the  independent  public  accountants  who  have  certified  HRPT's
         financial statements included in such registration statement, dated the
         effective date of such registration  statement,  covering substantially
         the same matters with respect to such  registration  statement (and the
         prospectus included in such registration statement) and, in the case of
         such accountants' letter, with respect to events subsequent to the date
         of such financial statements, as are customarily covered in opinions of
         issuer's counsel and in accountants'  letters delivered to underwriters
         in underwritten public offerings of securities;

                  (f) immediately  notify each seller of Registrable  Securities
         covered by such  registration  statement  and each Holder,  at any time
         when a prospectus  relating  thereto is required to be delivered  under
         the Securities  Act, upon discovery  that, or upon the happening of any
         event  as  a  result  of  which,   the  prospectus   included  in  such
         registration statement, as then in effect, includes an untrue statement
         of a material  fact or omits to state any material  fact required to be
         stated  therein  or  necessary  to  make  the  statements  therein  not
         misleading  in the  light of the  circumstances  then  existing,  which
         untrue  statement or omission  requires  amendment of the  registration
         statement or supplementation  of the prospectus,  and at the request of
         any such seller or Holder,  as soon as practicable  prepare and furnish
         to such  seller  and each  Holder a  reasonable  number  of copies of a
         supplement to or an amendment of such prospectus as may be necessary so
         that, as  thereafter  delivered to the  purchasers of such  Registrable
         Securities,  such prospectus shall not include an untrue statement of a
         material  fact or omit to state a material  fact  required to be stated
         therein or necessary to make the  statements  therein not misleading in
         the light of the circumstances then existing;  provided,  however, that
         each  Holder of  Registrable  Securities  registered  pursuant  to such
         registration  statement  agrees  that he will not sell any  Registrable
         Securities pursuant to such registration statement during the time that
         HRPT is preparing and filing with the  Commission a supplement to or an
         amendment of such prospectus or registration statement;

                  (g)  otherwise  use  its  best  efforts  to  comply  with  all
         applicable rules and regulations of the Commission,  and make available
         to its  securities  holders,  as soon  as  reasonably  practicable,  an
         earnings  statement  covering the period of at least twelve months, but
         not more than eighteen  months,  beginning  with the first month of the
         first fiscal  quarter  after the  effective  date of such  registration
         statement,  which  earnings  statement  shall satisfy the provisions of
         Section ll(a) of the Securities Act;

                  (h) provide and cause to be  maintained  a transfer  agent and
         registrar for all Registrable  Securities  covered by such registration
         statement  from and after a date not later than the  effective  date of
         such registration statement;

                  (i)   cause  all   Registrable   Securities   included   in  a
         registration  statement  to be listed on each  securities  exchange  on
         which similar  securities issued by HRPT are then listed and, if not so
         listed,  but similar  securities  are then listed on the NASD automated
         quotation system,  to be listed on the NASD automated  quotation system
         and, if listed on the NASD  automated  quotation  system,  use its best
         efforts to secure  designation of all such Registrable  Securities as a
         NASDAQ  national  market  system  security  within the  meaning of Rule
         11Aa2-1  of the  SEC or  failing  that,  at such  time as HRPT  becomes
         eligible for such  authorization,  to secure NASDAQ  authorization  for
         such  Registrable  Securities if available  and,  without  limiting the
         generality of the foregoing,  to arrange for at least two market makers
         to register as such with respect to such  Registrable  Securities  with
         the NASD; and

                  (j) enter into customary  agreements  (including  underwriting
         agreements  in  customary   form  but  subject  to  the  allocation  of
         Registration Expenses provided for in Section

                                        5

<PAGE>



         1.4) and take all such other actions reasonably requested by any Holder
         of  Registrable  Securities  in order to  expedite  or  facilitate  the
         disposition of such Registrable Securities.

Each seller of  Registrable  Securities  as to which any  registration  is being
effected  shall furnish to HRPT such  information  regarding such seller and the
distribution of such securities as shall be required by law or by the Commission
in connection therewith.

              5.3 Indemnification.

                  (a)  Indemnification  by HRPT.  HRPT shall  indemnify and hold
         harmless  the  seller  of any  Registrable  Securities  covered  by any
         registration  statement  filed  pursuant to Section 5.1, its directors,
         partners,  trustees and officers, each other person who participates as
         an  underwriter  in the  offering or sale of such  securities  and each
         other person,  if any, who controls such seller or any such underwriter
         within the meaning of the  Securities  Act against any losses,  claims,
         damages,  liabilities  or  expenses,  joint or  several,  to which such
         seller or Holder or any such  director or officer or  participating  or
         controlling  person  may become  subject  under the  Securities  Act or
         otherwise,  insofar as such losses,  claims,  damages,  liabilities  or
         expenses (or related actions or proceedings)  arise out of or are based
         upon (x) any  untrue  statement  or  alleged  untrue  statement  of any
         material fact contained in any registration  statement under which such
         securities  were  registered  under the Securities Act, any preliminary
         prospectus,  final prospectus or summary  prospectus  contained in such
         registration   statement,  or  any  amendment  or  supplement  to  such
         registration  statement,  or any document  incorporated by reference in
         such registration statement, or (y) any omission or alleged omission to
         state  therein  a  material  fact  required  to be  stated  therein  or
         necessary to make the statements therein not misleading,  and HRPT will
         reimburse such seller, Holder and each such director, trustee, officer,
         participating  person and controlling person for any legal or any other
         expenses  reasonably  incurred by them in connection with investigating
         or defending any such loss,  claim,  liability,  action or  proceeding,
         provided  that HRPT  shall not be liable in any such case to the extent
         that any such loss, claim,  damage,  liability or expense (or action or
         proceeding in respect thereof) arises out of or is based upon an untrue
         statement or alleged untrue  statement or omission or alleged  omission
         made in such registration  statement,  any such preliminary prospectus,
         final  prospectus,  summary  prospectus,  amendment  or  supplement  in
         reliance upon and in conformity with written  information  furnished to
         HRPT through an instrument  duly executed by such seller or such Holder
         or  any  such  director,  trustee,  officer,  participating  person  or
         controlling  person  specifically  stating  that  it is for  use in the
         preparation of such registration statement. Such indemnity shall remain
         in full force and effect regardless of any investigation  made by or on
         behalf of such  seller or such  Holder or any such  director,  officer,
         participating  person  or  controlling  person  and shall  survive  the
         transfer of such  securities  by such seller.  HRPT shall agree to make
         provision  for  contribution  relating  to such  indemnity  as shall be
         reasonably  requested by any seller of  Registrable  Securities  or the
         underwriters.

                  (b)   Indemnification  by  the  Sellers.  As  a  condition  to
         including  any  Registrable  Securities in any  registration  statement
         filed  pursuant  to  Section  5.1,  each  prospective  seller  of  such
         securities  hereby undertakes  severally and not jointly,  to indemnify
         and hold  harmless  (in the same  manner and to the same  extent as set
         forth in Section  5.3(a)) HRPT,  each director of HRPT, each officer of
         HRPT who shall sign such registration  statement and each other person,
         if any, who  controls  HRPT within the meaning of the  Securities  Act,
         with  respect  to  any  untrue  statement  in  or  omission  from  such
         registration statement, any preliminary prospectus, final prospectus or
         summary  prospectus  included in such  registration  statement,  or any
         amendment or supplement to such registration  statement,  of a material
         fact if such  statement  or omission  was made in reliance  upon and in
         conformity  with  written  information  furnished  to HRPT  through  an
         instrument duly executed by such seller specifically stating that it is
         for use in the preparation of

                                        6

<PAGE>



         such registration statement,  preliminary prospectus, final prospectus,
         summary  prospectus,  amendment or  supplement.  Such  indemnity  shall
         remain in full force and effect regardless of any investigation made by
         or on  behalf  of HRPT or any such  director,  officer  or  controlling
         person  and shall  survive  the  transfer  of such  securities  by such
         seller.

                  (c)  Notice of  Claims.  etc.  Promptly  after  receipt  by an
         indemnified  party of  notice  of the  commencement  of any  action  or
         proceeding  involving a claim  referred to in Sections  5.3(a) and (b),
         such  indemnified  party  will,  if a claim  is to be made  against  an
         indemnifying   party,   give  written  notice  to  the  latter  of  the
         commencement  of  such  action,   provided  that  the  failure  of  any
         indemnified  party to give notice  shall not  relieve the  indemnifying
         party of its  obligations  under Sections  5.3(a) or (b), except to the
         extent  that  the   indemnifying   party  is  actually  and  materially
         prejudiced  by such failure to give notice.  In case any such action is
         brought  against  an  indemnified  party,  unless  in such  indemnified
         party's  reasonable  judgment  (i) a conflict of interest  between such
         indemnified  and  indemnifying  parties  may exist in  respect  of such
         claim,  or (ii) the  indemnified  party has  available to it reasonable
         defenses which are different  from or additional to those  available to
         the indemnifying  party,  the  indemnifying  party shall be entitled to
         participate  in and to assume the defense of such action,  jointly with
         any other indemnifying party similarly notified,  to the extent that it
         may wish,  with counsel  reasonably  satisfactory  to such  indemnified
         party, and after notice from the indemnifying party to such indemnified
         party of its  election  so to assume the  defense of such  action,  the
         indemnifying  party shall not be liable to such  indemnified  party for
         any legal or other  expenses  subsequently  incurred  by the  latter in
         connection with the defense of such action other than reasonable  costs
         of investigation.  Notwithstanding  the foregoing,  in any such action,
         any  indemnified  party  shall have the right to retain its own counsel
         but the fees and  disbursements of such counsel shall be at the expense
         of such indemnified party unless (i) the indemnifying  party shall have
         failed  to  retain  counsel  for the  indemnified  party,  or (ii)  the
         indemnifying  party and such  indemnified  party  shall  have  mutually
         agreed to the  retention of such  counsel.  It is  understood  that the
         indemnifying  party shall not, in connection with any action or related
         actions  in  the  same  jurisdiction,   be  liable  for  the  fees  and
         disbursements  of  more  than  one  separate  firm  qualified  in  such
         jurisdiction to act as counsel for the indemnified  parties,  unless in
         any indemnified  party's reasonable judgment (i) a conflict of interest
         between  such  indemnified  party and any other  indemnified  party may
         exist in  respect of such  claims,  or (ii) the  indemnified  party has
         available  to it  reasonable  defenses  which  are  different  from  or
         additional  to  those  available  to  another  indemnified  party.  The
         indemnifying  party  shall  not be  liable  for any  settlement  of any
         proceeding  effected  without its written  consent but if settled  with
         such  consent or if there be a final  judgment for the  plaintiff,  the
         indemnifying  party agrees to indemnify the indemnified  party from and
         against any loss or liability by reason of such settlement or judgment.
         No  indemnifying  party shall,  without the consent of the  indemnified
         party,  consent to entry of any  judgment or enter into any  settlement
         which  does not  include  as an  unconditional  term the  giving by the
         claimant or plaintiff to such  indemnified  party of a release from all
         liability in respect to such claim or litigation.

                  (d) Other  Indemnification.  Indemnification  similar  to that
         specified  in  the  Sections   5.3(a)  and  5.3(b)  (with   appropriate
         modifications)  shall be given by HRPT and each  seller of  Registrable
         Securities   with  respect  to  any  required   registration  or  other
         qualification of such Registrable Securities under any federal or state
         law or regulation of  governmental  authority other than the Securities
         Act.

                  (e) Contribution.  If the indemnification provided for in this
         Section  5.3  is  unavailable  or  insufficient  to  hold  harmless  an
         indemnified   party  in  respect  of  any  losses,   claims,   damages,
         liabilities or expenses described as indemnifiable  pursuant to Section
         5.3(a)  or  5.3(b),  then each  indemnifying  party  shall,  in lieu of
         indemnifying such indemnified  party,  contribute to the amount paid or
         payable by such indemnified party, as a result of such losses,  claims,
         damages, liabilities

                                        7

<PAGE>



         or expenses in such  proportion as  appropriate to reflect the relative
         fault  of  HRPT,  on the  one  hand,  or  such  seller  of  Registrable
         Securities,  on the other hand,  and to the parties'  relative  intent,
         knowledge,  access to information and opportunity to correct or prevent
         any untrue  statement or omission  giving rise to such  indemnification
         obligation.  HRPT and the Holders of Registrable  Securities agree that
         it would not be just and  equitable if  contributions  pursuant to this
         Section  5.3(e) were  determined  by pro rata  allocation  (even if the
         Holders of Registrable  Securities  were treated as one entity for such
         purpose)  or by any  other  method  of  allocation  which  did not take
         account  of the  equitable  considerations  referred  to  above in this
         Section  5.3(e).  No  person  guilty  of  fraudulent  misrepresentation
         (within the meaning of Section  11(f) of the  Securities  Act) shall be
         entitled  to  contribution  from any  person  who is not guilty of such
         fraudulent misrepresentation.

                  (f)  Indemnification  Payments.  Periodic  payments of amounts
         required to be paid  pursuant to this  Section 5.3 shall be made during
         the  course of the  investigation  or  defense,  as and when  bills are
         received or expense, loss, damage or liability is incurred.

                  (g)  Limitation  on  Seller's  Payments.  Notwithstanding  any
         provision  of this  Agreement  to the  contrary,  the  liability of any
         seller of  Registrable  Securities  under this  Section 5.3 shall in no
         event  exceed the  proceeds  received  by such  seller from the sale of
         Registrable  Securities  covered by the  registration  statement giving
         rise to such liability.

              5.4  Registration  Expenses.  HRPT  shall  bear  all  Registration
Expenses  incurred in connection with the  performance of its obligations  under
Section 5.1 of this Agreement.

         6. Rule 144. HRPT shall comply with the  requirements of Rule 144 under
the  Securities  Act,  as such  Rule may be  amended  from  time to time (or any
similar rule or regulation  hereafter adopted by the Commission),  regarding the
availability of current public  information to the extent required to enable any
Holder  of  Registrable   Securities  to  sell  Registrable  Securities  without
registration  under the Securities Act pursuant to Rule 144 (or any similar rule
or regulation).  Upon the request of any Holder of Registrable Securities,  HRPT
will  deliver to such Holder a written  statement  as to whether it has complied
with such requirements.

         7.  Amendments and Waivers.  This Agreement may be amended and HRPT may
take any action herein prohibited, or omit to perform any act herein required to
be performed by it, only if HRPT shall have obtained the written consent to such
amendment, action or omission to act, of the Holder or Holders of 51% or more of
Registrable Securities (and, in the case of any amendment, action or omission to
act which adversely  affects any specific Holder of Registrable  Securities or a
specific group of Holders of Registrable Securities, the written consent of each
such Holder or Holders of 51% or more of the Registrable Securities held by such
group). Each Holder of any Registrable  Securities at the time shall be bound by
any  consent  authorized  by this  Section 7,  whether  or not such  Registrable
Securities shall have been marked to indicate such consent.

         8. Nominees for Beneficial  Owners.  In the event that any  Registrable
Securities  are  held  by a  nominee  for  the  beneficial  owner  thereof,  the
beneficial owner thereof may, at its election,  be treated as the Holder of such
Registrable Securities for purposes of any request or other action by any Holder
or  Holders  of  Registrable  Securities  pursuant  to  this  Agreement  or  any
determination of any number or percentage of Registrable  Securities held by any
Holder or Holders of Registrable Securities  contemplated by this Agreement.  If
the beneficial owner of any Registrable  Securities so elects,  HRPT may require
assurances reasonably satisfactory to it of such owner's beneficial ownership of
such Registrable Securities.


                                        8

         9.  Successors in Interest.  The parties  anticipate the liquidation of
Holder immediately  following the Effective Date.  Contemporaneously  therewith,
the former stockholders of Holder shall, by instrument  reasonably acceptable to
HRPT, become parties to this Agreement.

         10.  Successors and Assigns.  This Agreement  shall be binding upon and
inure to the benefit of and be  enforceable  by the  respective  successors  and
assigns of the parties to this  Agreement,  whether so expressed or not, and, in
particular,  shall inure to the benefit of and be  enforceable  by any Holder or
Holders of Registrable Securities.

         11. Notices.  All notices,  communications  and deliveries  required or
permitted by this Agreement  shall be made in writing signed by the Party making
the same,  shall specify the Section of this  Agreement  pursuant to which it is
given or being made and shall be deemed given or made (i) on the date  delivered
if  delivered  by telecopy or in person,  (ii) on the third (3rd)  business  day
after it is mailed if mailed by  registered  or certified  mail (return  receipt
requested) (with postage and other fees prepaid) or (iii) on the day after it is
delivered,  prepaid,  to an overnight  express delivery service that confirms to
the sender delivery on such day, as follows:

                  (a) if to any Holder of Registrable Securities, at the address
         shown on the  stock  transfer  books of HRPT  unless  such  Holder  has
         advised  HRPT in writing  of a  different  address as to which  notices
         shall be sent under this Agreement, and

                  (b) if to HRPT, at 400 Centre  Street,  Newton,  Massachusetts
         02158, Attn: David J. Hegarty, President, Telecopy No.: (617) 332-2281,
         with a copy to  Sullivan  &  Worcester  LLP,  One Post  Office  Square,
         Boston,  Massachusetts  02109,  Attn:  Alexander  A.  Notopoulos,  Jr.,
         Telecopy No: (617) 338-2880,

or to such  other  representative  or at such  other  address of a Party as such
Party  hereto may furnish to the other  Parties in  writing.  If notice is given
pursuant to this Section 10 of any assignment to a permitted successor or assign
of a Party  hereto,  the  notice  shall  be  given  as set  forth  above to such
successor or assign of such Party.

         12.  Miscellaneous.  HRPT  shall not  after the date of this  Agreement
enter into any agreement  with respect to its securities  which is  inconsistent
with or violates the rights granted to Holders of Registrable Securities in this
Agreement;  provided,  however,  that  HRPT  shall be  permitted  to enter  into
registration  rights  agreements with respect to Securities issued in connection
with acquisitions  consummated after the date of this Agreement.  This Agreement
embodies  the entire  agreement  and  understanding  between  HRPT and the other
parties to this Agreement relating to the subject-matter of this Agreement. This
Agreement shall be construed and enforced in accordance with and governed by the
law of the State of Delaware. The headings in this Agreement are for purposes of
reference  only and shall not limit or  otherwise  affect  the  meaning  of this
Agreement. This Agreement may be executed in any number of counterparts, each of
which shall be an  original,  but all of which  together  shall  constitute  one
instrument.

         13. HRPT  Limitation of Liability.  The Declaration of Trust of HRPT, a
copy of which is duly filed with the Department of  Assessments  and Taxation of
the State of Maryland,  provides that the name "Health and Retirement Properties
Trust" refers to the trustees under such  Declaration of Trust  collectively  as
trustees,  but not  individually  or personally,  and that no trustee,  officer,
shareholder,  employee or agent of HRPT shall be held to any personal liability,
jointly or severally, for any obligation of, or claim against, HRPT. All persons
dealing  with  HRPT in any way  shall  look  only to the  assets of HRPT for the
payment of any sum or the performance of any obligation.

                                 R E C I T A L:

         Pursuant to that certain Agreement of Merger,  dated as of February 17,
1997 (the "Merger  Agreement"),  between HRPT and Government Property Investors,
Inc., a Delaware  corporation  ("GPI"),  Government  Property  Holdings Trust, a
Maryland real estate  investment  trust  ("GPH"),  has of the date hereof merged
with and into HUB  Acquisition  Trust, a Maryland real estate  investment  trust
(the "Company"), and the subsidiaries of GPH have thereby become subsidiaries of
the Company (the "Acquisition").

         Upon the  consummation of the  Acquisition,  GPI will receive shares of
beneficial  interest,  par  value  $.01 per  share,  of HRPT (the  "HRPT  Common
Shares"),  as  consideration  for shares of the capital stock of GPH held by GPI
immediately  prior  to  the  consummation  of  the  Acquisition,  and  GPI  will
thereafter  liquidate  and dissolve and as a result the former  stockholders  of
GPI, including the Principal Shareholders, will become shareholders of HRPT.

         To  induce  HRPT  to   consummate   the   Acquisition,   the  Principal
Shareholders  are  willing to agree to the  restrictions  set forth  herein with
respect to the  transfer  and  voting of the HRPT  Common  Shares  issued to the
Principal  Shareholders  pursuant to the Merger Agreement and the liquidation of
GPI.

         NOW,  THEREFORE,  HRPT and the Principal  Shareholders  hereby agree as
follows:

         1.  Definitions.  The  capitalized  terms  set  forth  below  (in their
singular  and plural  forms as  applicable)  shall have the  meanings  set forth

individuals  other  than  individuals  who  at  the  beginning  of  such  period
constituted  the entire Board of Directors or Trustees  become a majority of the
Directors or Trustees; provided, in the case of HRPT Advisors, Inc., a change in
ownership  following the death or legal  incapacity of a shareholder as a result
of such shareholder's interest being held by his estate or legal representative,
shall not constitute a Change of Control.

              (d)  "Person":   an   individual,   partnership,   joint  venture,

to such Principal Shareholder's knowledge, holds directly, or is an Affiliate of
a Person who holds  directly,  5% or more of the aggregate HRPT Common Shares at
the time  outstanding  or (ii) make directly or indirectly or  participate in an
unsolicited offer to purchase any HRPT Common Shares.

         3.  Voting.  Until the  occurrence  of a Change in  Management,  unless

beneficial  interest,  par  value  $.01 per  share,  of HRPT (the  "HRPT  Common

GPI, including the Principal Shareholders, will become shareholders of HRPT.

         To induce the Principal Shareholders to approve the consummation of the
Acquisition,  HRPT is willing to agree to make certain information  available to

corporation,  limited  liability  company,  trust or any other form of  business
organization.

          2. Access to Information. Solely for the purpose of enabling the

may be obliged to execute and deliver an appropriate  confidentiality  agreement
to HRPT. The Principal  Shareholders  shall use all reasonable efforts to ensure
that their  respective  employees,  agents  and  outside  consultants  similarly
maintain the confidentiality of such proprietary and confidential information of

                  successors and assigns of any of the foregoing  (collectively,
                  the  "Indemnified  Parties"),   against  any  losses,  claims,
                  damages,  liabilities or expenses whenever arising or incurred
                  (including,  without  limitation,  amounts paid in settlement,
                  reasonable  costs of investigation  and reasonable  attorneys'
                  fees and expenses) (collectively, "Losses") (x) arising out of
                  or  relating to any breach of any  representation  or warranty
                  made by (i) GPI in the Merger  Agreement,  provided solely for
                  purposes of this Agreement,  each  representation and warranty
                  made by GPI  shall be deemed  to have  been  qualified  by the
                  phrase  "to the  knowledge  of GPI" (as  defined in the Merger
                  Agreement),   whether  or  not  so  qualified  in  the  Merger
                  Agreement, or (ii) GPI in Sections 3 and 4 of the Registration
                  Rights  Agreement  and Section  6(b) of this  Agreement or (y)
                  pursuant to Section 8.5 of the Merger Agreement.

                           (b) No  Indemnified  Party  shall be entitled to make
                  any claim for indemnification pursuant to this Agreement after
                  December 31, 1997 (the "Claim Period").

                           (i)      Promptly  after  receipt  by an  Indemnified
                                    Party of notice of the  commencement  of any
                                    action or  proceeding  involving  a claim to
                                    which  indemnification is being sought, such
                                    Indemnified  Party will, if a claim is to be
                                    made against GPI, give written notice to GPI
                                    of  the   commencement  of  such  action  or
                                    proceeding;  provided, however, that failure
                                    so to notify GPI shall not  relieve GPI from
                                    any  liability   which  GPI  may  have  with
                                    respect to such claim,  except to the extent
                                    that GPI is actually  materially  prejudiced
                                    by such failure to give notice.

                           (ii)     In case any such  action is brought  against
                                    an   Indemnified   Party,   unless  in  such
                                    Indemnified  Party's  reasonable  judgment a
                                    conflict of interest between the Indemnified
                                    Party and GPI may exist in  respect  of such
                                    claim,  GPI shall be  entitled to assume and
                                    control  the  defense of such  action to the
                                    extent  that  it  may  wish,   with  counsel
                                    reasonably  satisfactory to such Indemnified
                                    Party,  and  after  notice  from GPI to such
                                    Indemnified  Party  of  its  election  so to
                                    assume  and  control  the  defense  of  such
                                    action,  GPI  shall  not be  liable  to such
                                    Indemnified  Party  for any  legal  or other
                                    expenses subsequently incurred by the latter
                                    in  connection  with  the  defense  of  such
                                    action  other  than   reasonable   costs  of
                                    investigation.      Notwithstanding      the
                                    foregoing,   in   any   such   action,   any
                                    Indemnified  Party  shall  have the right to
                                    retain  its own  counsel,  but the  fees and
                                    disbursements  of such  counsel  shall be at
                                    the expense of such Indemnified Party unless
                                    GPI shall have failed to retain  counsel for
                                    the Indemnified Party. It is understood that
                                    GPI shall not, in connection with any action
                                    or related actions in the same jurisdiction,
                                    be liable for the fees and  disbursements of
                                    more than one  separate  firm  qualified  in
                                    such  jurisdiction to act as counsel for all
                                    Indemnified  Parties,  unless  in  any  such
                                    Indemnified  Party's  reasonable  judgment a
                                    conflict    of   interest    between    such
                                    Indemnified  Party and any other Indemnified
                                    Party may exist in  respect  of such  claim.
                                    GPI shall not be liable  for any  settlement
                                    of  any  proceeding   effected  without  the
                                    written  consent of GPI but if settled  with
                                    such consent or if there be a final judgment
                                    for the  plaintiff,  GPI agrees to indemnify
                                    the  Indemnified  Party from and against any
                                    loss  or   liability   by   reason  of  such
                                    settlement  or  judgment;   GPI  shall  not,
                                    without  the  consent  of  the   Indemnified
                                    Party,  consent to entry of any  judgment or
                                    enter  into any  settlement  which  does not
                                    include as an unconditional  term the giving
                                    by  the   claimant  or   plaintiff  to  such
                                    Indemnified  Party  of a  release  from  all
                                    liability   in  respect  to  such  claim  or
                                    litigation. Within five business days of the
                                    final  determination  of any such settlement
                                    or  judgment,  GPI  shall  deliver  or shall
                                    instruct  the Escrow Agent to deliver to the
                                    Indemnified  Party HRPT Common Shares issued
                                    in the Merger having a value,

                                    determined    under    Section     2(c)(iv),
                                    sufficient  to  satisfy  the  amount of such
                                    claim as finally determined.

                           (iii)    If an Indemnified  Party shall claim a right
                                    to payment  pursuant to this  Agreement with
                                    respect to which there has been no action or
                                    proceeding  involving such claim pursuant to
                                    Section  2(c)(i)  above,   such  Indemnified
                                    Party  shall  send  written  notice  of such
                                    claim to GPI.  Such notice shall specify the
                                    basis  for  such   claim.   As  promptly  as
                                    possible  after  the  Indemnified  Party has
                                    given such notice,  such  Indemnified  Party
                                    and  GPI  shall  establish  the  merits  and
                                    amount of such claim (by mutual agreement or
                                    arbitration)  and, within five business days
                                    of the final determination of the merits and
                                    amount of such claim,  GPI shall deliver (or
                                    shall  instruct the Escrow Agent to deliver)
                                    to the Indemnified  Party the amount of such
                                    claim as  finally  determined.  HRPT  Common
                                    Shares  issued in the Merger having a value,
                                    determined    under    Section     2(c)(iv),
                                    sufficient  to  satisfy  the  amount of such
                                    claim as finally determined.

                           (iv)     For  purposes  of  Paragraphs  2(c)(ii)  and
                                    2(c)(iii),  HRPT Common Shares issued GPI in
                                    the   Merger   that   are    delivered    in
                                    satisfaction of a claim made hereunder shall
                                    be valued at the greater of the closing sale
                                    price for an HRPT  Common  Share as reported
                                    by the NYSE for the  trading  day next prior
                                    to delivery or the Merger Price.

                  3.       Liability Limits.

                           (a) GPI shall have no liability for Losses until such
                  time as the aggregate of such Losses exceeds  $1,500,000  (the
                  "Deductible")   and   thereafter,   GPI  shall  indemnify  the
                  Indemnified  Parties for all Losses  incurred in excess of the
                  Deductible,  provided the limitation contained in this Section
                  3(a) shall not apply  with  respect  to Losses  arising  under
                  Section 8.5 of the Merger Agreement, and provided further that
                  Losses  pursuant to Section 8.5 of the Merger  Agreement shall
                  not  be  taken  into  account  in   determining   whether  the
                  Deductible has been met.

                           (b) Solely for purposes of this Agreement,  a Loss or
                  series of  related  Losses  shall be deemed to have a Material
                  Adverse Effect if the amount of such Loss or series of related
                  Losses exceeds $250,000.

                           (c)  In  the  case  of all  Premises  (including  the
                  College Park Premises and including Development Properties and
                  Contract  Properties acquired after the Closing Date) if there
                  shall be a Material  Adverse Effect and an  Indemnified  Party
                  (A) shall  make a claim for a Loss  with  respect  to which an
                  Indemnified Party is entitled to indemnification under Section
                  2 (a)  resulting  from (1) a reduction or offset of rent for a
                  period which is less than the  remaining  term of the lease or
                  (2) a  tenant  claim  for one  time  refund  of rent or  other
                  amounts,  then in either case, the amount of the Loss shall be
                  equal to such  offset,  reduction or tenant claim or (B) shall
                  make a claim for a Loss

                                       -3-

<PAGE>



                  with  respect to which an  Indemnified  Party is  entitled  to
                  indemnification  under Section 2(a) resulting from a reduction
                  or offset of rent for a period equal to the remaining  term of
                  the  lease,  then the amount of the Loss shall be equal to ten
                  (10) times the amount of such offset or reduction. In the case
                  of the College  Park  Premises,  if either (1) a reduction  in
                  rent  during  the  extension  period  from  the  rent for such
                  extension  period  set out by the terms of the  current  lease
                  and/or (2) a  reduction  in the GSA buyout  option  price,  as
                  contemplated  by Section 2.B or 2.C of the  Purchase  and Sale
                  Agreement with respect to the College Park Premises,  then the
                  amount of the Loss shall be equal to the present  value of (1)
                  the ten (10) year stream of such  reduction in rent during the
                  extension  period plus (2) the  reduction in the buyout option
                  price  ((1) and (2)  discounted  to the date of the claim at a
                  discount rate of 10%).

                           (d)  Notwithstanding  the preceding,  GPI's aggregate
                  liability for all Losses under this  Agreement  and, after the
                  Closing Date,  under the Merger Agreement shall not exceed and
                  shall be payable solely from the Second Closing  Consideration
                  (as adjusted). At the Second Closing, if any Indemnified Party
                  shall  have made a claim  hereunder  within  the Claim  Period
                  which remains outstanding, HRPT shall deliver to _____________
                  as escrow agent (the  "Escrow  Agent") a number of HRPT Common
                  Shares having a value (based on the Merger Price) equal to the
                  amount of such claim.

                  4.       Arbitration.

                           The  Parties  agree  that  any  and all  disputes  or
                  disagreements  arising out of or  relating to this  Agreement,
                  other than actions or claims for injunctive or other equitable
                  relief or claims raised in actions or  proceedings  brought by
                  third parties,  shall be resolved through  negotiations or, if
                  the  dispute  is not so  resolved,  through  mediation  and if
                  necessary      binding      arbitration      conducted      by
                  ____________________,  whose  decision shall be binding on all
                  parties  and  not  appealable.   Any  such  mediation   and/or
                  arbitration shall be conducted in _______________  pursuant to
                  the  procedures  set forth in Exhibit ___ attached  hereto and
                  made a part hereof and the arbitration rules and procedures of
                  ____________________.

         essence for each and every  provision of this  Agreement.  Whenever the
         last day for the exercise of any privilege or the discharge of any duty
         under this Agreement shall fall upon a Saturday,  Sunday or any date on

         the next succeeding day which is a regular business day.

                  8.  Successors  in  Interest.   The  parties   anticipate  the
         liquidation  of GPI  immediately  following  the  Effective  Date. As a
         condition of such liquidation and contemporaneously  therewith, certain
         holders of GPI Common  Stock listed on Exhibit A shall,  by  instrument
         reasonably  acceptable  to HRPT,  severally  assume  and  agree to pay,
         perform  and  observe  GPI's   obligations   under  this  Agreement  in
         accordance with their proportionate  interests set forth opposite their

                  9.  Captions.  The  titles  and  captions  contained  in  this
         Agreement  are  inserted  in  this   Agreement  only  as  a  matter  of
         convenience  and for reference and in no way define,  limit,  extend or
         describe the scope of this  Agreement or the intent of any provision of
         this  Agreement.  Unless  otherwise  specified  to  the  contrary,  all
         references to Sections are references to Sections of this Agreement.

                  10. Amendments. To the extent permitted by law, this Agreement
         may be amended by a subsequent writing signed by all of the Parties.

                  11. Controlling Law; Integration; Waiver. This Agreement shall
         be governed by and construed  and enforced in accordance  with the laws
         of the  Commonwealth of  Massachusetts.  This Agreement  supersedes all
         negotiations,  agreements  and  understandings  among the Parties  with
         respect to the subject  matter of this  Agreement and  constitutes  the
         entire  agreement  among the Parties to this Agreement  relating to the
         subject matter of this Agreement.  The failure of any Party at any time
         or times to require  performance  of any  provisions of this  Agreement
         shall no manner  affect the right to enforce the same. No waiver by any
         Party of any  conditions,  or of the  breach  of any  term,  provision,
         warranty,  representation,  agreement  or  covenant  contained  in this
         Agreement,  whether  by  conduct  or  otherwise,  in any  one  or  more
         instances  shall be deemed or  construed  as a  further  or  continuing
         waiver of any such  condition  or breach of any other term,  provision,
         warranty,  representation,  agreement  or  covenant  contained  in this
         Agreement.

                  12. Sole  Recourse.  The Parties  agree that the  remedies set

         Agreement and, after the Closing Date, under the Merger Agreement.

                  13.  Severability.  Any provision of this  Agreement  which is
         prohibited  or  unenforceable  in any  jurisdiction  will,  as to  such
         jurisdiction,  be  ineffective  to the  extent of such  prohibition  or
         unenforceability without invalidating the remaining

                                       -6-

         provisions   of  this   Agreement,   and  any   such   prohibition   or
         unenforceability  in any  jurisdiction  will not  invalidate  or render
         unenforceable such provision in any other  jurisdiction.  To the extent
         permitted by law, the Parties  waive any provision of law which renders
         any such provision prohibited or unenforceable in any respect.

                  14. HRPT Limitation of Liability.  The Declaration of Trust of
         HRPT, a copy of which is duly filed with the  Department of Assessments
         and Taxation of the State of Maryland,  provides  that the name "Health
         and  Retirement  Properties  Trust"  refers to the trustees  under such
         Declaration of Trust collectively as trustees,  but not individually or
         personally,  and that no  trustee,  officer,  shareholder,  employee or
         agent  of HRPT  shall be held to any  personal  liability,  jointly  or
         severally,  for any obligation of, or claim against,  HRPT. All persons
         dealing  with HRPT in any way shall look only to the assets of HRPT for
         the payment of any sum or the performance of any obligation.

                         SECOND CLOSING ESCROW AGREEMENT


         THIS SECOND CLOSING ESCROW AGREEMENT (this "Escrow  Agreement") is made
as of _________  __, 19__ by and among Health and  Retirement  Properties  Trust
("HRPT"),  ____________________ (the "Successor"), and ____________________ (the
"Escrow Agent").

                                 R E C I T A L:

         HRPT and GPI entered into a Merger Agreement (the "Merger  Agreement"),
an executed  copy of which has been  provided to the Escrow  Agent,  pursuant to
which  Government  Property  Holdings  Trust  ("GPH")  merged  with and into HUB
Acquisition  Trust  ("Merger  Sub") on the terms and conditions set forth in the
Merger Agreement.

         To induce  HRPT to  consummate  the  transactions  contemplated  by the
Merger Agreement,  GPI entered into an Indemnification  Agreement with HRPT, and
the Successor subsequently entered into an Accession Agreement,  executed copies
of which agreements have been provided to the Escrow Agent (such Indemnification
Agreement,  as  amended  by  such  Accession  Agreement,   the  "Indemnification
Agreement"), pursuant to which agreements the Successor agreed to indemnify HRPT
with  respect to certain  matters on the terms and  conditions  set forth in the
Indemnification Agreement.

         HRPT has made a claim for  Losses (as  defined  in the  Indemnification
Agreement)  which  has  not  been  resolved.  Pursuant  to  the  Indemnification
Agreement,  the Successor  has agreed to deposit an aggregate of _________  HRPT
Second Closing Shares (the "Escrowed Shares") into escrow upon execution of this
Escrow  Agreement  subject  to  the  terms  and  conditions  set  forth  in  the
Indemnification Agreement and in this Escrow Agreement.

         NOW, THEREFORE, the parties agree as follows:

         Section 1. Defined Terms. Terms not otherwise defined herein shall have
the  respective  meanings  prescribed  therefor in the Merger  Agreement and the
Indemnification Agreement.

         Section 2.  Appointment of Escrow Agent.  HRPT and the Successor hereby
appoint the Escrow  Agent as the escrow  agent to hold the  Escrowed  Shares (as
defined  below)  in  accordance  with the terms and  conditions  of this  Escrow
Agreement.

         Section 3. Delivery and Receipt of Escrowed Shares. Simultaneously with
the  execution of this Escrow  Agreement,  the  Successor  shall  deliver to the
Escrow Agent certificates representing the Escrowed Shares together with undated
stock  powers duly  executed in blank.  Receipt of the  Escrowed  Shares and the
related  stock  powers  is  hereby  acknowledged  by  the  Escrow  Agent.  Until
distributed  and released in  accordance  with the terms and  conditions of this
Escrow  Agreement,  the Escrow Agent shall hold in trust the Escrowed Shares and
the related stock powers.  If the Escrow Agent should  receive any cash or other
property in respect of the  Escrowed  Shares,  the Escrow Agent shall invest and
reinvest  such  cash  and  the  income  therefrom  in  any  money  market  fund,
substantially  all of which is  invested  in direct  obligations  of the  United
States of America or obligations  the principal of and the interest on which are
unconditionally  guaranteed  by the United States of America and shall hold such
other  property in trust  subject to the terms and  conditions  hereinafter  set
forth.

         Section 4. Release of Escrowed Shares. The Escrowed Shares shall secure
the obligations of the Successor pursuant to the  Indemnification  Agreement and
in accordance with the terms of


<PAGE>


                                       -2-

this Escrow  Agreement.  The Escrow  Agent shall  release  the  Escrowed  Shares
pursuant to a joint  direction in writing of HRPT and the  Successor or pursuant
to the decision of an arbitrator  pursuant to the  arbitration  proceedings  set
forth in  Section  4 of the  Indemnification  Agreement.  For  purposes  of this
Section,  each Escrowed Share shall be valued at the greater of the closing sale
price for an HRPT Common  Share as reported on the NYSE for the trading day next
prior to delivery or the Merger Price.

         Section 5. Termination of Escrow. The Escrow Agent shall distribute and
release any remaining  Escrowed  Shares (and, if  applicable,  any cash or other
property in respect of the Escrowed Shares,  and any income therefrom,  received
by the Escrow Agent) upon receipt of notice from HRPT and the Successor  that no
claim for  indemnification  made on or before the expiration of the Claim Period
(as defined in the Indemnification  Agreement) remains outstanding.  Such notice
shall specify the name and address of each party to whom the remaining  Escrowed
Shares (and, if applicable,  such cash, property and income) shall be delivered.
Promptly  after  receipt of such  notice,  the Escrow  Agent  shall  deliver the
certificates  representing such Escrowed Shares (and, if applicable,  such cash,
property and income) to each party so specified.  Upon  distribution and release
of such Escrowed  Shares (and, if applicable,  such cash,  property and income),
this Escrow  Agreement shall be deemed  terminated and the Escrow Agent shall be
released and discharged from all further obligations hereunder.

         Section 6. Duties of Escrow Agent.  The  acceptance by the Escrow Agent
of its duties as such under this Escrow  Agreement  is subject to the  following
terms and conditions, which HRPT and the Successor hereby agree shall govern and
control with respect to the rights,  duties,  liabilities  and immunities of the
Escrow Agent:

                  (a) The Escrow  Agent  shall not be liable for acting upon any
written  notice,  request,  waiver,  consent,  receipt  or other  instrument  or
document which the Escrow Agent in good faith believes to be genuine and what it
purports to be.

                  (b) It is understood  and agreed that the duties of the Escrow
Agent hereunder are purely ministerial in nature and that it shall not be liable
for any error of  judgment,  fact or law, or any act done or omitted to be done,
except for its own willful  misconduct,  breach of fiduciary  duty, bad faith or
gross negligence or that of its officers,  directors,  employees and agents. The
Escrow Agent's  determination  as to whether an event or condition has occurred,
or been met or satisfied,  or as to whether a provision of this Escrow Agreement
has been  complied  with, or as to whether  sufficient  evidence of the event or
condition or compliance  with the provision has been  furnished to it, shall not
subject the Escrow Agent to any claim, liability or obligation whatsoever,  even
if it shall  be found  that  such  determination  was  improper  and  incorrect,
provided, only, that the Escrow Agent and its officers, directors, employees and
agents  shall not have been guilty of willful  misconduct,  breach of  fiduciary
duty, bad faith or gross negligence in making such determination.

                  (c) The Escrow Agent may consult with, and obtain advice from,
legal counsel including its own officers, employees and partners in the event of
any dispute or question as to the  construction of any of the provisions  hereof
or its duties  hereunder,  and it shall  incur no  liability  and shall be fully
protected  in  acting  in  good  faith  in  accordance   with  the  opinion  and
instructions of such counsel.

                  (d) In the  event  of any  disagreement  or lack of  agreement
between  HRPT and the  Successor  of  which  the  Escrow  Agent  has  knowledge,
resulting or which might result in adverse claims or demands with respect to the
Escrowed Shares, the Escrow Agent shall be entitled, in its sole discretion,  to
refuse to comply  with any claims or demands on it with  respect  thereto  until
such matter shall be resolved, and in so refusing, the Escrow Agent may elect to
make no delivery or other  disposition of the Escrowed  Shares,  and in so doing
the Escrow Agent shall not be or become  liable in any way to either HRPT or the
Successor for its failure or refusal to comply


<PAGE>


                                       -3-

with such claims or demands,  and it shall be entitled to continue so to refrain
from acting, and so to refuse to act, until all such claims or demands (i) shall
have been finally determined by a court of competent jurisdiction, or (ii) shall
have been  resolved by the  agreement of HRPT and the  Successor  and the Escrow
Agent shall have been notified thereof in writing.

                  (e) The Escrow  Agent may  resign at any time upon  giving ten
(10) days' notice to HRPT and the Successor  and may appoint a successor  escrow
agent  hereunder so long as such successor shall accept and agree to be bound by
the  terms of this  Escrow  Agreement  and shall be  acceptable  to HRPT and the
Successor. It is understood and agreed that the Escrow Agent's resignation shall
not be effective until a successor  escrow agent agrees to be bound by the terms
of this Escrow Agreement.

         Section 7. No  Representations  by Escrow Agent. The Escrow Agent makes
no  representation  as to the validity,  value,  genuineness,  negotiability  or
collectibility  of any  security  or other  document  or  instrument  held by or
delivered to or by it.

         Section 8. Obligations of Escrow Agent. The Escrow Agent shall be under
no obligation to institute or defend any actions,  suits or legal proceedings in
connection  herewith  or take any other  action  likely to involve it in expense
unless first indemnified to its reasonable satisfaction.

         Section 9. Expenses. The reasonable  out-of-pocket expenses (including,
without  limitation,  reasonable legal fees and  disbursements)  incurred by the
Escrow Agent in the  performance  of its duties  hereunder  shall be  reimbursed
one-half  by  the  Successor  and  one-half  by  HRPT.  Such  reimbursement  for
out-of-pocket  expenses  shall be made by cash  payment to the Escrow Agent from
time to time upon its written  request.  The Escrow Agent shall have no right or
lien with respect to the Escrowed Shares for payment of such expenses. Except as
otherwise herein or in the Merger Agreement  provided,  each party shall pay its
own  expenses  incident  to  the  negotiation,   preparation,   performance  and
enforcement  of this Escrow  Agreement  (including  all fees and expenses of its
counsel, accountants and other consultants, advisors and representatives for all
activities of such persons undertaken pursuant to this Escrow Agreement), except
to the extent, if any, otherwise specifically set forth in this Agreement.

         [Section 10. Escrow Agent Status.  _____ hereby  acknowledges  that the
Escrow Agent is counsel to _____ and agrees that it will not seek to  disqualify
the Escrow  Agent from acting and  continuing  to act as counsel to _____ in the
event of a dispute  hereunder or in the course of the defense or  prosecution of
any claim  relating  to the  transactions  contemplated  hereby or by the Merger
Agreement;  provided,  however, that in the event of a dispute, the Escrow Agent
shall (a) immediately seek to appoint a successor  escrow agent,  which shall be
acceptable to HRPT and the Shareholders,  having no business  relationships with
HRPT or the  Shareholders  and (b)  immediately  resign upon  acceptance of such
appointment  and agreement to be bound by the terms of this Escrow  Agreement by
such successor escrow agent.]

         Section 11. Assignment;  Successors and Assigns.  This Escrow Agreement
shall not be assignable  by any party  without the prior written  consent of the
other parties.

         Nothing in this Escrow Agreement expressed or implied is intended to or
shall be  construed  to  confer  upon or create in any  Person  (other  than the
parties  hereto  and their  permitted  successors  and  assigns)  any  rights or
remedies under or by reason of this Agreement,  including without limitation any
rights to enforce this Escrow Agreement.

         Section 12. Specific Performance; Other Rights and Remedies. Each party
recognizes and agrees that the other party's remedy at law for any breach of the
provisions  of this Escrow  Agreement  would be  inadequate  and agrees that for
breach of such provisions,  such party shall, in addition to such other remedies
as may be  available  to it at law or in equity or as  provided  in this  Escrow
Agreement,  be  entitled  to  injunctive  relief and to enforce its rights by an
action for specific


<PAGE>


                                       -4-

performance to the extent  permitted by applicable law. Each party hereby waives
any  requirement  for  security  or the  posting of any bond or other  surety in
connection  with any temporary or permanent  award of  injunctive,  mandatory or
other  equitable  relief.   Nothing  herein  contained  shall  be  construed  as
prohibiting  either party from pursuing any other  remedies  available to it for
such breach or threatened  breach,  including without limitation the recovery of
damages.

         Section 13. Entire  Agreement.  This Escrow  Agreement  constitutes the
entire  agreement  between the parties with respect to the subject matter hereof
and  supersedes  all  prior  agreements,   arrangements,   covenants,  promises,
conditions,  understandings,   inducements,  representations  and  negotiations,
expressed or implied, oral or written, between them as to such subject matter.

         Section 14. Waivers;  Amendments.  Anything in this Escrow Agreement to
the contrary  notwithstanding,  amendments to and  modifications  of this Escrow
Agreement  may  be  made,  required  consents  and  approvals  may  be  granted,
compliance with any term, covenant, agreement,  condition or other provision set
forth  herein  may be omitted or waived,  either  generally  or in a  particular
instance and either  retroactively  or  prospectively  with,  but only with, the
written consent of the party entitled to the benefit thereof.

provision of this Escrow  Agreement  are required or permitted to be given shall

         Section 16.  Severability.  If any  provision of this Escrow  Agreement
shall be held or  deemed  to be,  or shall  in fact  be,  invalid,  inoperative,
illegal or  unenforceable  as applied to any particular case in any jurisdiction
or  jurisdictions,  or in all  jurisdictions  or in all  cases,  because  of the

or unenforceable in any other  jurisdiction or in any other case or circumstance
or of rendering any other  provision or  provisions  herein  contained  invalid,
inoperative,  illegal or  unenforceable to the extent that such other provisions
are not themselves actually in conflict with such constitution,  statute or rule
of public policy,  but this Escrow  Agreement shall be reformed and construed in
any  such  jurisdiction  or case as if such  invalid,  inoperative,  illegal  or
unenforceable  provision  had never been  contained  herein  and such  provision
reformed so that it would be valid,  operative  and  enforceable  to the maximum
extent permitted in such jurisdiction or in such case.

income or cash flow  statements  of Borrower or any of its  Subsidiaries  or any
other  Person  (each  of the  foregoing  being a  "Calculation  Item"),  if such
Calculation  Item is owed or otherwise  recorded or measured in GBP or any other
currency other than U.S.  Dollars,  the amount or value of the Calculation  Item
shall be calculated in U.S. Dollars and shall be the amount of U.S. Dollars that
can be  purchased  with GBP or such other  currency  calculated  on the basis of
Administrative  Agent's spot rate of exchange  for the purchase of U.S.  Dollars
with GBP or such  other  currency  on the date such  calculation  is to be made;
provided that  notwithstanding the continuous nature of certain  representations
and  covenants  in  this  Agreement,  unless  requested  to do so  by  Agent  or
Administrative Agent or unless

       
                                       26

Borrower is aware of any material currency movement or other  circumstance which
would be reasonably  likely to have an effect on its ability to satisfy any such
representation  or  covenant,  Borrower  shall  not be  required  to  make  such
calculation with respect to such representations and covenants at any time other
than in  connection  with  the  delivery  of a Real  Property  Statement  or the
delivery of the  certificate  of a Responsible  Officer  under  Section  5.2(b);
provided further that even if not required to make such calculations, nothing in
this  Section  1.3(a)  shall  be  construed  to  in  any  way  limit  Borrower's
obligations to satisfy all such representations and covenants in accordance with
their terms.

                  (b) Administrative Agent shall calculate the Equivalent Amount
of Loans  denominated  in GBP: (i) after any  Borrowing  Date on which Loans are
made such that the aggregate  principal amount of Loans outstanding  exceeds 75%
of the Commitments and if requested by Agent or if  Administrative  Agent in the
reasonable  exercise  of its  judgment  considers  it  desirable  to  make  such
calculation  to  monitor  compliance  by  Borrower  with the limits set forth in
Section  2.1, on the final  Business Day of each  Interest  Period for each Loan
denominated in GBP or otherwise as often as  Administrative  Agent  considers it
desirable or necessary to make such calculation and  Administrative  Agent shall
notify  Borrower  and  Agent  if,  based  on such  calculation,  Borrower  is in
compliance  with the  requirements  of Section 2.1 as to the  maximum  aggregate
outstanding  principal amount of Loans denominated in GBP or whether  prepayment
of the Loans is  necessary as required by Section  2.8(e);  (ii) on any proposed
Borrowing  Date  to  determine  whether,  after  giving  effect  to  a  proposed
borrowing, Borrower will be in compliance with such requirements of Section 2.1;
and (iii) on any  proposed  continuation/conversion  date under  Section  2.5 to
determine whether, after giving effect to such proposed continuation/conversion,
Borrower will be in compliance with such  requirements of Section 2.1;  provided
that any failure by  Administrative  Agent to make such  calculations or provide
the  information  under this Section 1.3(b) shall not affect the  obligations of
Borrower  to comply  with the limits set forth in Section  2.1 or  otherwise  to
satisfy all representations and covenants made by it in this Agreement.


                  SECTION 2.  AMOUNT AND TERMS OF REVOLVING LOANS

                  2.1.  Revolving Loans.

                  (a) Each Lender severally (and not jointly) agrees, subject to
the terms and conditions  hereof,  to continue the Existing Loans outstanding on
the  Effective  Date,  to make Loans to  Borrower  from time to time  during the
period from the Effective Date to and including the Final Borrowing Date, and to
maintain its Loans outstanding to Borrower on the Final Borrowing Date from such
date until the Termination Date, up to an aggregate amount  (including,  without
limitation, the amount of any Existing Loans) or the Equivalent Amount in GBP at
any one time not exceeding its Pro Rata Share of the aggregate  Commitments  (as
defined below) to be used for the purposes identified in Section 2.11 ; provided
that in no event  shall  the  aggregate  outstanding  principal  amount of Loans
denominated in GBP at any time exceed the Equivalent  Amount of $100,000,000 (as
determined in accordance with Section 1.3(b)). Each Loan hereunder shall be made
by Lenders in accordance with their respective Pro Rata Share. Upon satisfaction
of the  conditions set forth in Section 4, (i) all loans  outstanding  under the
Existing Loan Agreement

       
                                       27

<PAGE>



as of, and at the time of, the Effective Date ("Existing  Loans") and all rights
relating to the Existing  Loans and all other rights  arising under the Existing
Loan  Agreement  and  all  documents  relating  thereto,  except  to the  extent
specifically amended and restated by this Agreement,  shall be assigned (without
any further  action or  authorization  being  required) by the lenders under the
Existing Loan Agreement to the Lenders  proportionately  to their respective Pro
Rata Shares of the  Commitments  without  recourse,  representation  or warranty
(except for  representations  and warranties made in this Section 2.1(a)) of any
nature,  express or implied, by any such lender and such Existing Loans shall be
continued and deemed to be Loans for all purposes  under this Agreement and (ii)
each Lender shall pay to Administrative Agent its Pro Rata Share of the Existing
Loans  or,  if less,  the  amount  by which  such Pro  Rata  Share  exceeds  its
outstanding  Existing Loans (if any), for  distribution to the lenders under the
Existing Loan  Agreement that are not Lenders and to the other Lenders that have
funded such Loans, in accordance  with their  respective  Commitments,  and each
Lender's  share  of  the  Existing  Loans  shall  be  adjusted  accordingly.  In
connection  with such  assignment,  each Lender shall be deemed to represent and
warrant to each other Lender that (i) it is, and will be on the Effective  Date,
prior to the assignment of its interests  pursuant to this Section  2.1(a),  the
legal and  beneficial  owner of the interests  being assigned and such interests
are, and will be on the Effective  Date, free and clear of any adverse claim and
(ii) the total aggregate  principal amount and accrued interest,  fees and other
amounts due to such Lender under the Existing  Loan  Agreement on March 29, 1996
are as set forth on Schedule 3 annexed hereto.  Any amounts of accrued interest,
commitment  fees or other amounts  (other than  principal)  owed (whether or not
presently due and payable) by Borrower to the lenders under or in respect of the
Existing Loans shall,  as of the Effective Date, be deemed to be due and payable
to the lenders  under the  Existing  Loan  Agreement.  The  continuation  of the
Existing  Loans  hereunder  shall not be deemed to be a repayment  thereof,  and
Borrower  shall not be required to deliver any notice of prepayment or notice of
borrowing or to satisfy any condition relating to minimum amounts of prepayments
or minimum amounts of borrowings  hereunder with respect to such  continuance of
the Existing Loans.

                  (b) Each  Lender's  commitment  to make and maintain  Loans to
Borrower pursuant to this Section 2.1 is herein called its "Commitment" and such
commitments of all Lenders in the aggregate are herein called the "Commitments".
The original  amount of each Lender's  Commitment is set forth opposite its name
on  Schedule  1  annexed  hereto  and  the  aggregate  original  amount  of  the
Commitments  is  $250,000,000;  provided  that  up to an  Equivalent  Amount  of
$100,000,000  may be  made  in  Loans  denominated  in  GBP  (as  determined  in
accordance  with  Section  1.3(b));  provided  further  that the  amount  of the
Commitments  shall be reduced from time to time by the amount of any  reductions
thereto  made  pursuant to Section 2.7 (with a  proportionate  reduction  of the
amount  of the  Commitments  otherwise  available  for the  borrowing  of  Loans
denominated in GBP);  provided  further that Lenders shall have no obligation to
make or maintain Loans hereunder to the extent any such Loan would (i) cause the
aggregate amount of the Loans then outstanding to exceed the Commitments or (ii)
cause the aggregate  amount of the General  Corporate Loans then  outstanding to
exceed 25% of the  Commitments;  and provided further that Lenders shall have no
obligation to make or maintain Loans  denominated in GBP hereunder to the extent
any such Loan would cause the aggregate  amount of the Loans  denominated in GBP
then outstanding to exceed the Equivalent  Amount of $100,000,000 (as determined
in accordance with Section 1.3(b)).

<PAGE>



                   (c) Each Lender's  Commitment shall expire on the Termination
Date and all Loans and all other  amounts  owed  hereunder  with  respect to the
Loans and the Commitments shall be paid in full no later than that date.

                  (d) Subject to the other terms and conditions hereof, Borrower
may borrow under this Section 2.1,  repay Loans in accordance  with Section 2.10
or prepay  Loans in  accordance  with  Section 2.8 and  reborrow  the amounts so
repaid under this Section 2.1.

                  2.2.  Notes;  Maturity Date. The Loans of each Lender pursuant
hereto shall be evidenced by, and be repayable with interest in accordance  with
the terms of, a promissory note of Borrower substantially in the form of Exhibit
A, with  appropriate  insertions,  payable  to the  order of such  Lender in the
principal   amount  of  the  Commitment  of  such  Lender   (together  with  any
replacement,  modification,  renewal or  substitution  thereof,  individually  a
"Note" and collectively,  the "Notes"),  which shall be dated the Effective Date
and be duly  completed,  executed and  delivered by Borrower.  The Loans of each
Lender  pursuant  hereto shall be made and  maintained by such Lender's  Lending
Office(s) as designated by such Lender from time to time. All outstanding  Loans
and each of the Notes shall  mature and  Borrower  shall  repay the  outstanding
principal  amount of such Loans and the Notes in full  together  with all unpaid
interest  accrued  thereon on the  Termination  Date (or earlier as  hereinafter
provided)  (or if such day is not a Business  Day, the next  preceding  Business
Day) all in accordance with Section 2.10(b), and shall be subject to payment and
prepayment  as  provided in Section 2.8  hereof.  Each Lender is  authorized  to
endorse  at any  time  the  date  and  amount  of  each  Loan or  conversion  or
continuation  thereof,  the date and amount of each  payment of  principal  with
respect to its Loans and whether its Loans are Base Rate Loans, Eurodollar Loans
or Alternate Rate Loans, on the schedule  annexed to and  constituting a part of
such Lender's Note, which  endorsement  shall constitute prima facie evidence of
the accuracy of the information endorsed.

                  2.3.  Procedure for Borrowing.

                  (a) Whenever  Borrower desires to borrow under Section 2.1, it
shall  deliver  both a Notice of  Borrowing  and a Real  Property  Statement  to
Administrative  Agent  (with a copy of each to Agent) no later  than  11:00 A.M.
(New York time) in the case of Base Rate Loans at least one  Business Day and in
the case of  Eurodollar  Loans at least  three  Business  Days in advance of the
proposed  Borrowing Date. The Notice of Borrowing shall specify (i) the proposed
Borrowing Date (which shall be a Business  Day),  (ii) whether such Loans are to
be  denominated  in U.S.  Dollars or,  subject to the limit in Section 2.1, GBP,
(iii) the  amount of the Loans  requested  (which  amount  shall be in a minimum
aggregate  amount of $1,000,000 and integral  multiples of $500,000 in excess of
that  amount if the Loans are to be  denominated  in U.S.  Dollars  or a minimum
aggregate  amount of GBP  1,000,000  and  integral  multiples  of GBP 500,000 in
excess of that amount if the Loans are to be denominated  in GBP),  (iv) whether
such Loans will be Base Rate Loans or Eurodollar  Loans and, if Eurodollar Loans
are specified,  the initial Interest Period requested for such Eurodollar Loans,
(v) Borrower's account at Administrative  Agent to which the net proceeds of the

thereof  are  so  designated,  the  amount  of  such  portion,  (vii)  that  the
representations and warranties contained in the Loan Documents are true, correct
and accurate in all material respects to the same extent as though

       
                                                        29

made on and as of the date of such  Notice  of  Borrowing  unless  stated in the
relevant Loan Document to relate to a specific  earlier date, in which case such
representations  and  warranties  shall be true,  correct  and  complete  in all
material respects as of such earlier date, (viii) that no event has occurred and
is continuing or would result from the proposed  borrowing that would constitute
a Default or Event of Default,  (ix) that the amount of the  proposed  borrowing
will not cause (A) the aggregate  outstanding  principal  amount of the Loans to
exceed the  Commitments  currently in effect,  (B) the  aggregate  amount of the
General Corporate Loans then outstanding to exceed 25% of the Commitments or (C)
the aggregate amount of the Loans  denominated in GBP then outstanding to exceed
the Equivalent  Amount of $100,000,000 (as determined in accordance with Section
1.3(b)),  (x)  that the  proceeds  of the  proposed  borrowing  (other  than any
proceeds  of  General  Corporate  Loans)  shall be used to make  payment  on the
proposed Borrowing Date for the purchase price and costs of acquiring  interests
in one or more  Facilities  due and payable on such Borrowing Date and (xi) with
respect to the amount of such Loans which will not be General  Corporate  Loans,
the following:

                           (x)  the  name  of  the  proposed   Operators  and/or
                  Mortgagors  (as  applicable)  of the Facility or Facilities to
                  which such borrowing  relates and any Credit Support  Obligors
                  in relation thereto;

                           (y)  the  name  and  location  of  such  Facility  or
                  Facilities,  the  Appraised  Value(s)  thereof and each of the
                  other costs,  values and prices  referred to in the definition
                  of  "Allowed  Value"  therefor,   and  a  description  of  the
                  interests of Borrower or any of its Subsidiaries therein to be
                  acquired with the proceeds of such borrowing; and

                           (z) if the  proceeds  of  such  Loan  will be used to
                  acquire an interest in any Facility which interest is required
                  to be an Eligible  Property or Eligible  Mortgage  included in
                  the calculation of Indebtedness permitted under Section 6.8(a)
                  after  giving  effect  to  such  Loan,  certification  to that
                  effect.

                  In lieu of delivering the above-described Notice of Borrowing,
         Borrower  may  give  Administrative   Agent  telephonic  notice  (which
         telephonic  notice  shall be  followed  immediately  with a  notice  by
         facsimile  telecopy)  by the time  specified  for a Notice of Borrowing
         above; provided that such notice shall be promptly confirmed in writing
         by delivery of a Notice of Borrowing and a Real  Property  Statement to
         Administrative  Agent and Agent on or before the  applicable  Borrowing
         Date;  provided  further that in the event of a  discrepancy  between a
         Notice of Borrowing and such telephonic  notice,  the telephonic notice
         shall govern. Except as otherwise provided in Sections 2.13 and 2.14, a
         Notice of Borrowing (or  telephonic  notice in lieu thereof as provided
         above) shall be  irrevocable,  and Borrower  shall be bound to make the
         borrowing  specified in such Notice of Borrowing (or telephonic  notice
         in lieu thereof as provided above) in accordance therewith.

                  None of Agent,  Administrative Agent or any Lender shall incur
any liability to any Person  (including  Borrower or any of its Subsidiaries) in
acting upon any telephonic notice referred to above that Administrative Agent or
Agent believes in good faith to have been given by a duly authorized  officer or
other Person authorized to borrow on behalf of

       
                                       30

<PAGE>



Borrower or  otherwise  acting in good faith under this  Section  2.3,  and upon
funding of Loans by Lenders in accordance  with this  Agreement  pursuant to any
such telephonic  notice Borrower shall have effected the borrowing of such Loans
hereunder.

                  (b) All Loans  under this  Agreement  shall be made by Lenders
simultaneously  and  proportionately  to their respective Pro Rata Shares of the
Commitments,  it being  understood  that no Lender shall be responsible  for any
default by any other  Lender in that  other  Lender's  obligation  to make Loans
requested  hereunder  nor  shall the  Commitment  of any  Lender  to make  Loans
requested  hereunder  be  increased or decreased as a result of a default by any
other  Lender  in  that  other  Lender's  obligation  to  make  Loans  requested
hereunder.  Promptly  after  receipt  by  Administrative  Agent of a  Notice  of
Borrowing  pursuant  to Section  2.3(a) (or  telephonic  notice in lieu  thereof
followed  immediately with a notice by facsimile  telecopy) and in any event not
later than 2:00 p.m. (New York time) on the preceding  Business Day (in the case
of Base Rate Loans) or at least three  Business  Days (in the case of Eurodollar
Loans) in advance of the proposed  Borrowing  Date,  Administrative  Agent shall
notify each  Lender of the  relevant  details of the  proposed  borrowing.  Each
Lender shall make the amount of its Loan available to  Administrative  Agent, in
immediately available funds, at the account specified by Administrative Agent to
the Lenders,  not later than 11:00 A.M.  (New York time) on the  Borrowing  Date
specified in the applicable Notice of Borrowing.  Upon satisfaction or waiver of
the  applicable   conditions  precedent  specified  in  Sections  4.1  and  4.2,
Administrative Agent shall make the proceeds of such Loans available to Borrower
on such Borrowing Date by causing an amount of immediately available funds equal
to the proceeds of all such Loans received by Administrative  Agent from Lenders
to be credited to the account at  Administrative  Agent as specified by Borrower
in the Notice of Borrowing.

                  Unless  Administrative  Agent shall have been  notified by any
Lender  prior to the  Borrowing  Date for any Loans  that such  Lender  does not
intend to make  available to  Administrative  Agent the amount of such  Lender's
Loan  requested  on such  Borrowing  Date (and any such notice  shall be without
prejudice   to  any  rights  of  Borrower   against   such  Lender   hereunder),
Administrative  Agent may assume that such Lender has made such amount available
to Administrative  Agent on such Borrowing Date and Administrative Agent may, in
its sole discretion, but shall not be obligated to, make available to Borrower a
corresponding amount on such Borrowing Date. If such corresponding amount is not
in fact made available to  Administrative  Agent by such Lender,  Administrative
Agent shall be entitled to recover such corresponding amount on demand from such
Lender  together with interest  thereon,  for each day from such  Borrowing Date
until the date such amount is paid to Administrative  Agent, at the Base Rate in
the case of Loans  denominated  in U.S.  Dollars or at the Alternate GBP Rate in
the  case  of  Loans  denominated  in GBP.  If such  Lender  does  not pay  such
corresponding  amount  forthwith upon  Administrative  Agent's demand  therefor,
Administrative   Agent  shall  promptly   notify  Borrower  and  Borrower  shall
immediately pay such corresponding  amount to Administrative Agent together with
interest  thereon,  for each day from such  Borrowing  Date  until the date such
amount is paid to  Administrative  Agent,  at the Base Rate in the case of Loans
denominated  in U.S.  Dollars or at the  Alternate GBP Rate in the case of Loans
denominated  in GBP.  Nothing in this Section 2.3 shall be deemed to relieve any
Lender from its obligation to fulfill its Commitments  hereunder or to prejudice
any rights that  Borrower may have against any Lender as a result of any default
by such Lender hereunder.

<PAGE>



                  2.4.  Interest.

                  (a) Generally.  Each Loan shall be a Eurodollar Loan or a Base
Rate Loan as selected by Borrower initially at the time a Notice of Borrowing is
given pursuant to Section 2.3(a) or as selected  pursuant to Section 2.5 (or, in
the case of any Existing Loans, as in effect on the Effective Date),  except for
any portion of a Eurodollar  Loan which is  converted to an Alternate  Rate Loan
pursuant  to  Section  2.13 or 2.14.  Loans  shall bear  interest  on the unpaid
principal  amount  thereof  from the date made (or, in the case of any  Existing
Loans,  from the  Effective  Date) to  maturity  (whether  by  accelerations  or
otherwise), at the interest rates specified as follows:

                             (i)  in  the  case  of a  Eurodollar  Loan,  at  an
                  interest  rate per annum for and during each  Interest  Period
                  equal to the  LIBO  Rate for  such  Interest  Period  plus the
                  Applicable Margin in effect from time to time;

                            (ii)  in the  case  of the  Base  Rate  Loan,  at an
                  interest  rate per annum equal to the Base Rate in effect from
                  time to time plus the Applicable Margin in effect from time to
                  time; and

                           (iii)  in  the  case  of  an   Alternate   Rate  Loan
                  (including  any Alternate GBP Rate Loan),  at an interest rate
                  per annum equal to the  Alternate  Rate in effect from time to
                  time plus the Applicable Margin in effect from time to time,

                  plus, in the case of any Loan denominated in GBP and made by a
Lender subject to such requirements, Mandatory Liquid Asset Costs.

Borrower  shall  pay  interest  on the  unpaid  principal  amount  of the  Loans
outstanding  from time to time, in arrears,  (i) on each Interest  Payment Date,
(ii) on the Termination  Date, (iii) in the currency required by Section 2.10(b)
and (iv) in  accordance  with Section  2.4(b) (where  applicable).  In addition,
Borrower shall pay accrued interest on the principal amount of any Loans prepaid
in accordance with Section 2.8 on the date of any such prepayment.

                  (b) Default Interest. If Borrower shall default in the payment
of the  principal  of or interest  on any portion of a Loan or any other  amount
becoming due  hereunder or under any of the Loan  Documents,  Borrower  shall on
demand from time to time pay  interest  (to the extent  permitted  by law in the
case of interest on overdue interest) on such defaulted amount accruing from and
including the date of such default (without reference to any period of grace) up
to and including the date of actual payment  (after as well as before  judgment)
at a rate per  annum  which is the sum of (i) two  percent  (2%)  plus  (ii) the
greatest of the LIBO Rate,  the  Alternate  Rate or the Base Rate plus (iii) the
Applicable Margin.
Interest under this Section 2.4(b) shall be payable upon demand.

                  (c) Interest Determination. Upon determining the LIBO Rate for
each  Interest  Period,  the  Alternate  Rate for any period or the Base Rate in
effect from time to time,  Administrative  Agent shall promptly  notify Borrower
and Lenders thereof by telephone  (confirmed promptly in writing) or in writing.
Such  determination  shall,  in the absence of manifest error, be conclusive and
binding upon Borrower and the Lenders.

                  2.5.    Duration    of    Interest    Period;     Notice    of
Continuation/Conversion.

                  (a)  Borrower  may,  pursuant  to  the  applicable  Notice  of
Borrowing or Notice of  Continuation/Conversion,  as the case may be,  select an
Interest Period to be applicable to each Eurodollar Loan.

                  (b)  Subject  to the  provisions  of  Sections  2.13 and 2.14,
Borrower  shall  have the  option  (i) to convert at any time all or any part of
outstanding  Base Rate Loans to Eurodollar  Loans or (ii) upon the expiration of
any Interest  Period  applicable  to  Eurodollar  Loans,  to continue all or any
portion of such Loans as Eurodollar  Loans or convert all or any portion of such
Loans  to Base  Rate  Loans,  as the case may be,  and the  succeeding  Interest
Period(s) of such  continued  Loans shall  commence on the most recent  Interest
Payment Date  therefor;  provided  that Loans may be continued  as, or converted
into,  Eurodollar  Loans with a particular  Interest Period only in an aggregate
amount equal to $1,000,000 and integral  multiples of $500,000 in excess of that
amount if the Loans are to be denominated in U.S. Dollars or a minimum aggregate
amount of GBP 1,000,000 and integral  multiples of GBP 500,000 in excess of that
amount if the  Loans are to be  denominated  in GBP (but  subject  always to the
determinations  described  in Section  1.3(b) and the limits in Section  2.1 for
Loans denominated in GBP); provided further that Eurodollar Loans or any portion
thereof may only be converted into Base Rate Loans on the expiration date of the
Interest Period(s)  applicable  thereto;  and provided further that (i) no event
has   occurred   and  is   continuing   or   would   result   from   such   Loan
continuation/conversion that would constitute a Default or Event of Default, and
(ii) the  representations  and warranties  contained in Section 3 shall be true,
correct  and  complete  in all  material  respects  on  and  as of the  proposed
continuation/  conversion  date to the same  extent as though  made on and as of
that date unless stated in such section to relate to a specific earlier date, in
which  case such  representations  and  warranties  shall be true,  correct  and
complete in all material  respects as of such earlier date. All  conversions and
continuations of Loans shall be made  simultaneously  and on a pro rata basis by
the Lenders in accordance with their respective Pro Rata Shares.

                  Borrower shall deliver a Notice of Continuation/ Conversion to
Administrative  Agent  (with a copy to Agent to follow) no later than 11:00 A.M.
(New York City time) at least  three  Business  Days in advance of the  proposed
continuation/ conversion date (in the case of a conversion to, or a continuation
of, Eurodollar Loans) or at least three Business Days in advance of the proposed
conversion  date (in the case of a conversion  to Base Rate Loans).  A Notice of
Continuation/Conversion  shall specify (i) the proposed  continuation/conversion
date  (which  shall be a  Business  Day),  (ii) the  amount  of the  Loans to be

specific earlier date, in which case such  representations  and warranties shall
be true,  correct and complete in all material respects as of such earlier date,
and (vi) that no event has occurred and is  continuing  or would result from the
proposed  continuation/conversion  that would  constitute  a Default or Event of
Default.    In   lieu   of   delivering    the    above-described    Notice   of
Continuation/Conversion,  Borrower  may  give  Administrative  Agent  telephonic
notice by the time specified for delivery of a Notice of

       
                                       33

Continuation/Conversion   above  (which  telephonic  notice  shall  be  followed
immediately with a notice by facsimile telecopy);  provided that in the event of
a discrepancy  between a Notice of  Continuation/Conversion  and such telephonic
notice, such telephonic notice shall govern.

                  Promptly after receipt by Administrative  Agent of a Notice of
Continuation/Conversion  pursuant  to this  Section  2.5 (or  telephonic  notice
followed immediately with a notice by facsimile telecopy),  and in any event not
later than 2:00 p.m. (New York time) at least three  Business Days in advance of
the proposed  continuation/conversion  date,  Administrative  Agent shall notify
each Lender of the relevant details of the proposed continuation/conversion.

                  None of Agent,  Administrative Agent or any Lender shall incur
any liability to any Person  (including  Borrower) in acting upon any telephonic
notice  referred to above that  Administrative  Agent or Agent  believes in good
faith to have been given by a duly authorized officer or other person authorized
to act on behalf of  Borrower or for  otherwise  acting in good faith under this
Section 2.5, and upon the continuation  and/or conversion (as applicable) of any
Loan in accordance with this Agreement  pursuant to any such telephonic  notice,
Borrower shall have effected a continuation  and/or  conversion (as  applicable)
hereunder of such Loan.

                  Except as  otherwise  provided  in Sections  2.13 and 2.14,  a
Notice of  Continuation/Conversion  (or telephonic notice in lieu thereof) shall
be irrevocable from and after the giving thereof, and Borrower shall be bound to
effect a continuation and/or conversion (as applicable) in accordance therewith.

                  2.6.  Fees.

                  (a) Borrower shall pay to Administrative Agent for the account
of each Lender,  in  accordance  with its Pro Rata Share of the  Commitments,  a
facility fee in an amount equal to the Applicable Facility Fee Percentage of the
average daily balance of such Lender's  Commitment in respect of each  quarterly

Borrowing Date.  Borrower shall pay to  Administrative  Agent for the account of

facility fee in an amount equal to the Applicable Facility Fee Percentage of the
average daily balance of such Lender's Outstandings in respect of each quarterly
period  during the period from the Final  Borrowing  Date to but  excluding  the
Final Repayment Date. Such fees shall be calculated  quarterly and be payable in
arrears on (x) the last Business Day of March,  June,  September and December of
each year until the Final  Repayment Date and (y) the Final  Repayment Date, and

                  (b) Borrower  shall on the date this Agreement is delivered by

in accordance with its Pro Rata Share of the  Commitments,  an upfront fee in an
amount equal to 0.150% of the  Commitments,  all in  accordance  with the letter
agreement dated February 5, 1996 between Agent and Borrower.

                  (c) Borrower  shall on the date this Agreement is delivered by

the  account of each  Lender such fees in such amount as may have been agreed in
writing between Agent and Borrower.

                  (d) Borrower shall pay to Administrative Agent for its account
an annual administration fee payable in such amounts and according to such terms
as are set forth in a separate letter agreement between Administrative Agent and
Borrower,  the  first  such  payment  to be due on the date  this  Agreement  is
delivered by the parties hereto.

                  2.7.  Termination or Reduction of  Commitment.  Borrower shall
have the right,  upon not less than five Business Days' notice to Administrative
Agent,  to terminate the  Commitments  or, from time to time, to reduce pro rata
the  amount  of the  Commitments,  to the  extent,  in  either  case,  that  the
Commitments are undrawn.  Any such reduction shall be in an amount of $1,000,000
or any integral  multiple  thereof and shall reduce  permanently  the  aggregate
amount of the Commitments then in effect, with a proportionate  reduction of the
amount  of the  Commitments  otherwise  available  for the  borrowing  of  Loans
denominated in GBP.

                  2.8.  Optional Prepayments; Mandatory Prepayments.

                  (a) Subject to Sections 2.8(f) and 2.15,  Borrower may, at its
option,  prepay  any  Loans on any  Business  Day in  whole or in part,  without
premium, upon at least three Business Days', in the case of Eurodollar Loans, or
one Business  Day's,  in the case of Base Rate Loans,  prior  written  notice to
Administrative  Agent,  specifying  the  amount of  prepayment.  Each  notice of
prepayment  pursuant  to this  clause (a) shall be  irrevocable  and the payment
amount  specified in such notice shall be due and payable on the date  specified
in the currency  required by Section 2.10(b),  together with accrued interest to
such date on the Loans and all  amounts  (if any)  payable  pursuant  to Section
2.15.  Partial  prepayments of the Loans pursuant to this clause (a) shall be in
an aggregate  principal  amount of  $1,000,000  (or GBP  1,000,000)  or integral
multiples of $500,000 (or GBP 500,000) in excess of that amount.

                  (b) In the  event  of any  sale or  other  disposition  of any
interest in any Facility, any Lease termination,  or any other event giving rise
to Net Property Proceeds or Net Mortgage Proceeds,  on the final Business Day of
the first  Interest  Period to expire  after the  closing  of such sale or other
disposition  or, if such closing  occurs at a time when there are no  Eurodollar
Loans  outstanding,  on the final  Business  Day of the month  during which such
closing occurs, Borrower shall apply an amount equal to all of such Net Property
Proceeds and Net Mortgage  Proceeds (other than any amount thereof  required and
used to satisfy  Indebtedness secured by a Lien, not inconsistent with the terms
of this  Agreement,  on the relevant  Properties  or Mortgage  Interests) to the
prepayment of the Loans; provided that with respect to a particular  transaction
or a related series of transactions  giving rise to Net Property Proceeds or Net
Mortgage  Proceeds,  prepayment  of the Loans  shall be  required  from such Net
Property  Proceeds  or Net  Mortgage  Proceeds  only to the extent that the same
exceed  $5,000,000;  provided  further that no  prepayment  shall be required in
respect of Loans  denominated  in GBP to the extent  the  aggregate  outstanding
principal  amount of such Loans does not exceed the  Allowed  Value of  Eligible
Properties and Eligible Mortgages in respect of Properties located in the United
Kingdom acquired with or funded with GBP.

                  (c) In the event of any (i) public or private  offering  by or
on behalf of  Borrower of debt or equity  securities  issued by Borrower or (ii)
incurrence by Borrower of  Indebtedness  to one or more financial  institutions,
within thirty days after such offering or  incurrence,  Borrower shall apply all
Net  Securities  Proceeds  arising  from  such  offering  or  incurrence  to the
prepayment  of the Loans or, at the option of  Borrower,  to the  prepayment  of
other  Indebtedness  of Borrower  outstanding  on the Effective  Date;  provided
further that no prepayment shall be required in respect of Loans  denominated in
GBP to the extent the aggregate  outstanding principal amount of such Loans does
not exceed the Allowed Value of Eligible  Properties  and Eligible  Mortgages in
respect of Properties located in the United Kingdom acquired with or funded with
GBP.

                  (d)  The  Loans   shall  be  subject   to  certain   mandatory
prepayments  pursuant to and upon the occurrence of the events  described in the
provisions of Sections 2.13 and 2.14.

                  (e) If at any time the principal  balance of the Loans exceeds
the  Commitments,  Borrower  shall  promptly (and in any event no later than two
Business Days after becoming aware thereof) repay Loans to the extent  necessary
to reduce the aggregate  outstanding  principal amount thereof to an amount that
is equal to or less than the Commitments.  If at any time the principal  balance
of the General Corporate Loans then outstanding  exceeds 25% of the Commitments,
Borrower  shall promptly (and in any event no later than two Business Days after
becoming aware thereof) repay General Corporate Loans to the extent necessary to
reduce the aggregate  outstanding  principal amount thereof to an amount that is
equal to or less  than  25% of the  Commitments.  If at any  time the  principal
balance  of the  Loans  denominated  in GBP  exceeds  the  Equivalent  Amount of
$100,000,000 (as determined in accordance with Section  1.3(b)),  Borrower shall
promptly (and in any event no later than two Business Days after  becoming aware
thereof) repay Loans  denominated  in GBP to the extent  necessary to reduce the
aggregate  outstanding principal amount thereof to an amount that is equal to or
less than the Equivalent  Amount in GBP of $100,000,000;  provided that, so long
as no Default or Event of  Default  has  occurred  and is  continuing,  any such
repayment  of the  Loans  denominated  in  GBP  may be  made  at the  end of the
applicable   Interest   Periods  on  condition   that  Borrower   deposits  with
Administrative  Agent  cash in an amount  equal to the  amount  of the  required
prepayment at the time  otherwise  required for  prepayment  (such amounts to be
held as cash collateral by Administrative  Agent pending such repayment on terms
satisfactory to Agent, Administrative Agent and Borrower).

                  (f) Subject to the  application  of the payment  provisions of
Section 2.10(a), any prepayments of the Loans pursuant to this Section, Sections
2.13 or 2.14, or any other provision of any Loan Document shall be applied first
to any amounts payable with respect thereto pursuant to Section 2.15,  second to
the  payment  of  accrued  and  unpaid  interest  on  the  principal  amount  of
outstanding  General Corporate Loans up to and including the date of prepayment,
third, to the payment of accrued and unpaid interest on the principal  amount of
all other outstanding  Loans up to and including the date of prepayment,  fourth
to the  principal  amount  of such  General  Corporate  Loans,  and fifth to the
principal amount of all other outstanding Loans.  Subject to the requirements of
the  preceding   sentence,   Borrower  may  designate  the  application  of  any
prepayments,  to be applied to principal on the Loans, to the Eurodollar  Loans,
Base Rate Loans and/or Alternate Rate Loans, as it may select,  provided that if
Borrower does not designate such application,  such prepayments shall be applied
(x) first to outstanding  Base Rate Loans,  (y) second to outstanding  Alternate
Rate

Loans and (z) third to outstanding Eurodollar Loans.

                  2.9.  Computation of Interest and Fees. Fees and other amounts
other  than  interest  calculated  on the  basis  of a rate per  annum  shall be
computed on the basis of a 360-day year for the actual days elapsed. Interest on
the Base Rate Loans and on the Alternate Rate Loans, in each case, calculated by
reference to the prime rate and interest on the Eurodollar Loans  denominated in
GBP  shall be  computed  on the  basis of a  365-day  year for the  actual  days
elapsed,  while interest on the Eurodollar Loans denominated in U.S. Dollars and
interest  on the  Alternate  Rate Loans and the Base Rate  Loans,  in each case,
where  interest is not  calculated  by  reference  to the prime  rate,  shall be
computed on the basis of a 360-day year for the actual days elapsed.

                  2.10.  Payments and Currency.  (a) Except as  contemplated  by
this  Agreement,  the  borrowing  by Borrower  from the  Lenders,  each  payment
(including  each  prepayment) by Borrower on account of principal,  interest and
fees required under Sections  2.6(a) and (b), and any reduction of the amount of
the Commitments of the Lenders hereunder,  shall be made for the account of each
Lender according to its Pro Rata Share; provided that payments to the Lenders of
interest based upon the Alternate Rate shall be allocated  appropriately to give
effect to differences among the Lenders' respective costs of funds. All payments
(including  prepayments)  by Borrower on account of principal,  interest,  fees,
costs,  indemnities or other amounts payable  hereunder or under any of the Loan
Documents  shall  be  made  to  Administrative  Agent  for  the  account  of the
applicable Lenders (except for fees required under Section 2.6(c) which shall be
only for the account of  Administrative  Agent and Agent,  respectively)  at the
account of Administrative  Agent specified in Section 10.3(b) and in immediately
available  funds in the currency  required by Section  2.10(b).  Each payment or
prepayment  hereunder and under the Notes and the other Loan Documents  shall be
made  without  set-off  or  counterclaim  and free and  clear  of,  and  without
deduction  for,  any present or future  withholding  or other  taxes,  duties or
charges of any nature imposed on or attributable to such payments or prepayments
by or on behalf of any Governmental Authority, except for any Excluded Taxes. If
any such taxes (other than any Excluded  Taxes),  duties or charges  (including,
without  limitation,  any tax, duty or charge imposed by Sections 1, 2 and/or 39
of the  Massachusetts  General  Laws,  Chapter 63, as  currently in effect or as
amended hereafter or any analogous provisions (or provisions having an analogous
effect)  of the laws,  rules or  regulations  (or  interpretations  thereof)  of
Massachusetts or any other  Governmental  Authority) are so levied or imposed on
or are  attributable  to any such  payment  or  prepayment,  Borrower  will make
additional  payments in such  amounts as may be necessary so that the net amount
received by a Lender,  after  withholding  or deduction for or on account of all
such taxes,  duties or charges,  will be equal to the amount provided for herein
or in such  Lender's  Note or in any of the other Loan  Documents.  Whenever any
taxes, duties or charges are payable by Borrower with respect to or attributable
to any payments or prepayments  hereunder or under any of the Notes or any other
Loan Document,  Borrower agrees to furnish promptly to Administrative  Agent for
the account of the applicable  Lender official  receipts or copies  thereof,  if
reasonably available, evidencing payment of any such taxes, duties or charges so
withheld or deducted. If Borrower fails to pay any such taxes, duties or charges
when due to the  appropriate  taxing  authority after receipt of notice that any
such taxes, duties or charges are due, or fails to remit to Administrative Agent
for the account of the  applicable  Lender the customary  evidence of payment of
any such taxes, duties or charges so withheld or deducted, Borrower shall

       
                                       37

<PAGE>



indemnify  the  affected  Lender for any  incremental  taxes,  duties,  charges,
interest or penalties  that may become payable by such Lender as a result of any
such failure.  During the continuance of any Default,  Administrative Agent may,
but  shall  be  under  no  obligation   to,  apply  all  payments   received  by
Administrative  Agent from Borrower pursuant to any of the Loan Documents in the
following order of payment regardless of the application designated by Borrower:
first to any  interest  owing  under  Section  2.4(b)  or under  any of the Loan
Documents  other  than  interest  owing on the Loans and the Notes  referred  to
below,  second to any fees then  payable to Agent,  Administrative  Agent or the
Lenders,  third to any amounts  owing  pursuant to Section  10.7,  fourth to any
amounts owing pursuant to Sections 2.13,  2.14 or 2.15,  fifth to any other sums
(other than principal on the Loans and the Notes and interest  thereon  referred
to below) owing under any of the Loan Documents,  sixth to any interest owing on
the Loans and Notes and seventh to the  repayment of the  principal of the Loans
and the Notes as  designated  by  Administrative  Agent;  provided  that if such
application  is  other  than in  accordance  with  any  express  designation  by
Borrower,   Administrative   Agent  shall  promptly   notify  Borrower  of  such
application. Administrative Agent will distribute each payment to the applicable
Lenders promptly upon receipt thereof (and in any event on the same Business Day
as the date when received, if such payment is received at or prior to 12:00 noon
(New York time)). Each payment by Administrative Agent to a Lender shall be made
for the account of such Lender's  Lending Office as designated by such Lender to
Administrative  Agent in writing  from time to time.  Whenever any payment to be
made hereunder or under any Loan Document,  including,  without limitation,  any
principal of or interest on any Loan, shall become due and payable,  or whenever
the last day of any Interest Period would otherwise occur, on a day which is not
a Business  Day,  such payment  shall be made and the last day of such  Interest
Period shall occur on the next  succeeding  Business  Day and such  extension of
time shall in such case be  included  in  computing  interest  on such  payment;
provided that if such  extension  would cause any such payment to be made in the
next succeeding calendar month, or the last day of such Interest Period to occur
in the next succeeding  calendar month, such payment shall be made, and the last
day of such Interest Period shall occur, on the next preceding Business Day.

                  (b) A repayment or  prepayment of a Loan or any part of a Loan
is  payable in the  currency  in which the Loan was  denominated  at the time at
which such Loan was made to Borrower  by Lenders.  Interest in respect of a Loan
is payable in the currency in which the principal portion of the respective Loan
in respect of which it is payable is denominated. Fees in respect of Commitments
or otherwise  hereunder  shall be payable in U.S.  Dollars.  Amounts  payable in
respect of costs, expenses and taxes and the like are payable in the currency in
which they are  incurred.  Any other amount  payable  under this  Agreement  is,
except as otherwise provided in this Agreement, payable in U.S. Dollars.

                  2.11.  Use of Proceeds.  The  proceeds of the Loans  hereunder
shall be used by Borrower  (either directly or indirectly  through  intercompany
advances of such proceeds as permitted under Section 6.8(d) to its Subsidiaries;
provided that,  Church Creek  Corporation may not receive any such proceeds) for
(a) the  acquisition of Properties;  (b) the  acquisition or funding of Mortgage
Interests;  and (c) the direct or indirect  reimbursement of the issuing bank of
the letter of credit  supporting the obligations of Church Creek  Corporation in
respect of the IDFA Indebtedness;  provided that the General Corporate Loans may
be used by Borrower and its Subsidiaries for their respective  general corporate
purposes; provided further that the Existing Loans may be continued for the same
purposes as they were made

       
                                       38

under the Existing Loan Agreement, and shall not be treated as General Corporate
Loans.

                  2.12.  Increased Costs.

                  (a) If any Requirement of Law or other event or condition,  or
any  amendment,  modification  or  interpretation  thereof  (including,  without
limitation,  any request,  recommendation,  guideline or policy,  whether or not
having  the  force of law,  of or from any  central  bank or other  Governmental
Authority), in any such case, adopted,  effective, made or issued after the date
hereof (but in any event including, without limitation, Regulation D and Section
1, 2 and/or 39 of the  Massachusetts  General  Laws,  Chapter 63 as currently in
effect or as amended hereafter or any analogous provisions (or provisions having
an  analogous  effect) of the laws,  rules or  regulations  (or  interpretations
thereof) of Massachusetts or any other Governmental  Authority) by any authority
charged with the administration or interpretation thereof:

                             (i)  subjects  Agent,  Administrative  Agent or any
         Lender or any branch or  Affiliate  of Agent,  Administrative  Agent or
         such Lender to any tax (except Excluded Taxes), fee,  deduction,  duty,
         withholding,  levy,  impost or other charge or reduction of any nature,
         on or with  respect to, or which  Agent,  Administrative  Agent or such
         Lender in its sole discretion  deems applicable or attributable to this
         Agreement, any Note, any of the other Loan Documents, its Commitment or
         its pro rata share of the Loans,  or  interest,  fees or other  amounts
         attributable thereto or to any of the foregoing; or

                            (ii)  changes  the basis of  taxation of payments to
         any Lender or any branch or  Affiliate  of such Lender of  principal of
         and/or  interest  on such  share of the  Loans  and/or  other  fees and
         amounts  payable  hereunder or under any of the Loan  Documents or with
         respect  hereto or thereto  (including  in any event  imposition  of or
         change in any withholding taxes, but excluding any Excluded Taxes); or

                           (iii)  imposes  upon,  modifies,  requires,  makes or
         deems  applicable to any Lender,  or any of its branches or Affiliates,
         any  regular,  special,  supplementary  or  other  reserve  or  deposit
         requirement,  insurance  assessment or similar  requirement  against or
         affecting  any assets held by, or  liabilities  of, or deposits with or
         for the  account of,  such  Lender or such  branch or  Affiliate,  with
         respect to or which Agent or such Lender in its sole  discretion  deems
         applicable or  attributable  to this  Agreement,  any Note,  any of the
         other  Loan  Documents,  its  Commitment  or its pro rata  share of the
         Loans, or interest,  fees or other amounts  attributable  thereto or to
         any of the foregoing; or

                            (iv)  imposes,  modifies  or  deems  applicable  any
         condition or  requirement  upon or causes in any manner the addition of
         any supplement to, or increase of any kind to, the capital or cost base
         of  Agent,  Administrative  Agent  or any  Lender  or  such  branch  or
         Affiliate,  for extending or maintaining its Commitment or its pro rata
         share  of the  Loans  which  results  in an  increase  in  the  capital

         other  Loan  Documents,  its  Commitment  or its pro rata  share of the
         Loans, or interest,  fees or other amounts  attributable  thereto or to
         any of the foregoing; or

         Lender or any branch or  Affiliate  of Agent,  Administrative  Agent or
         such  Lender any other  conditions  with  respect to, or  allocable  or
         attributable in good faith by Agent, Administrative Agent or the Lender
         to, this  Agreement,  any Note, any of the other Loan Documents or such
         share of the Loans or its Commitment  hereunder or such interest,  fees
         or other amounts;

and the  result  of any of the  foregoing,  based  solely  upon the  good  faith
determination  and allocation by Agent,  Administrative  Agent or any Lender, as
the case may be, of costs, decreased benefits and/or reduced amount of payments,
is to  increase  the  cost or  decrease  the  benefit,  in any  way,  to  Agent,
Administrative  Agent  or such  Lender,  as the case may be,  or any  branch  or
Affiliate of Agent,  Administrative Agent or such Lender, as the case may be, of
funding or maintaining its Commitment or its share of the Loans hereunder, or to
reduce the amount of any payment (whether of principal,  interest, or otherwise)
received or receivable  by Agent,  Administrative  Agent or such Lender,  as the
case may be, or any branch or Affiliate of Agent,  Administrative  Agent or such
Lender,  as the case may be, or to require Agent,  Administrative  Agent or such
Lender, as the case may be, or any branch or Affiliate of Agent,  Administrative
Agent or such Lender,  as the case may be, to make any payment,  then and in any
such case:

                  (1) Agent,  Administrative  Agent or such Lender,  as the case
         may be, shall promptly notify Borrower and the other Lenders in writing
         of the happening of such event;

                  (2) Agent,  Administrative  Agent or such Lender,  as the case
         may be,  shall  promptly  deliver to Borrower  and the other  Lenders a
         certificate  stating  the  change or event  which has  occurred  or the
         reserve or capital  requirements  or other  conditions  which have been
         imposed on Agent,  Administrative Agent or such Lender, as the case may
         be, or  branch or  Affiliate  of  Agent,  Administrative  Agent or such
         Lender, as the case may be, or the request,  recommendation,  guideline
         or policy with which it has  complied,  together with the date thereof,
         the amount of such  increased  cost,  decreased  benefit  or  reduction
         payment; and

                  (3)  Borrower  shall pay Agent,  Administrative  Agent or such
         Lender,  as the case may be,  promptly  on  demand  such an  amount  or
         amounts as:

                           (A) in the case of events referred to in clauses (i),
                  (ii),  (iii) and (v) and,  if  applicable,  clause (iv) above,
                  shall  be  sufficient  to  compensate  it or  such  branch  or
                  Affiliate for all such increased  costs and/or payments and/or
                  decreased benefits, and/or reduced amount of payment; and/or

                           (B) in the case of events  referred to in clause (iv)
                  above, shall be an

       
                                       40

<PAGE>



                  amount equal to the  reduction,  as  reasonably  determined by
                  Agent,  Administrative  Agent or such Lender,  as the case may
                  be, in the after-tax rate of return on Agent's, Administrative
                  Agent's  or such  Lender's  capital  resulting  from  any such
                  capital or increased  capital or similar  requirement,  all as
                  certified  by Agent,  Administrative  Agent or such  Lender or
                  Lenders,  as the  case  may be,  in  said  written  notice  to
                  Borrower.  Such certification  shall be conclusive and binding
                  on Borrower absent manifest error.

                  The certificate of Agent,  Administrative Agent or such Lender
as to the additional  amounts payable pursuant to this Section 2.12 delivered to
Borrower shall  constitute  prima facie evidence of the amount  thereof.  Agent,
Administrative  Agent  and each  Lender  agree  to use  reasonable  efforts,  as
determined by Agent, Administrative Agent or such Lender, as the case may be, to
avoid or minimize the payment by Borrower of any  additional  amounts under this
Section 2.12. The protection provided by this Section 2.12 shall be available to
Agent,   Administrative  Agent  and  each  Lender  regardless  of  any  possible
contention  of  invalidity  or   inapplicability  of  the  Requirement  of  Law,
interpretation,  recommendation,  guideline,  policy or event or condition which
has been imposed or has occurred.  In the event that after  Borrower  shall have
paid any  additional  amount  under this  Section 2.12 with respect to the Loans
Agent,  Administrative  Agent or such Lender shall have  successfully  contested
such Requirement of Law, interpretation,  recommendation,  guideline,  policy or
event or condition then, to the extent that Agent,  Administrative Agent or such
Lender will be placed in the same position it was in prior to the  incurrence of
the  increased  cost or  reduction  in  amount  received  or  receivable  (on an
after-tax  basis),  but without  giving  effect to interest  which may have been
earned on the  additional  amount  paid by  Borrower  (but with  interest to the
extent actually  earned by Agent,  Administrative  Agent or such Lender,  as the
case may be, on such amount as determined by Agent, Administrative Agent or such
Lender, as the case may be), Agent,  Administrative Agent or such Lender, as the
case may be,  shall  refund  to  Borrower  such  additional  amount  (with  such
interest, if any).

                  2.13.  Change in Law Rendering  Eurodollar  Loans or Alternate
Rate Loans Unlawful; Failure to Give Notice of Continuation.

                  (a) Notwithstanding anything to the contrary herein contained,
in  the  event  that  any  Requirement  of Law or  any  change  in any  existing
Requirement  of  Law  or in  the  interpretation  thereof  by  any  Governmental
Authority charged with the administration  thereof, in any case adopted,  issued
or effective after the date hereof, (i) shall make it unlawful for any Lender to
fund any portion of the Eurodollar Loans or to give effect to its obligations as
contemplated hereby with respect to its making or maintaining its pro rata share
of the Eurodollar  Loans,  or (ii) shall make it unlawful for any Lender to fund
any portion of the Alternate Rate Loans or to give effect to its  obligations as
contemplated  hereby with respect to its Commitment or making or maintaining its
pro rata  share  of the  Alternate  Rate  Loans,  such  Lender  shall,  upon the
happening of such event, notify Agent,  Administrative  Agent, the other Lenders
and Borrower  thereof in writing  stating the reason  therefor and the effective
date of such event, and (x) upon the effectiveness of any such event referred to
in clause (i) above,  the  obligation of such Lender to make or maintain its pro
rata share of the Eurodollar  Loans to Borrower shall forthwith be suspended for
the duration of such  illegality and during such  illegality  such Lender shall,
upon  payment of any  amounts  owing  under  Section  2.15 with  respect to such
conversion, convert its share of the Eurodollar

       
                                       41

<PAGE>



Loans to Alternate Rate Loans or (upon  effectiveness of any such event referred
to in clause (ii) and during the  continuance  of such event) Base Rate Loans in
the case of Loans denominated in U.S. Dollars or Alternate GBP Rate Loans in the
case of Loans  denominated  in GBP, and (y) upon the  effectiveness  of any such
event  referred  to in clause  (ii),  the  obligation  of such Lender to make or
maintain  its pro rata  share of the  Alternate  Rate  Loans to  Borrower  shall
forthwith  be  suspended  for the  duration of such  illegality  and during such
illegality  such Lender  shall,  upon payment of any amounts owing under Section
2.15 with respect to such  conversion,  convert its share of the Alternate  Rate
Loans to Base Rate  Loans in the case of Loans  denominated  in U.S.  Dollars or
Alternate  GBP Rate Loans in the case of Loans  denominated  in GBP. If and when
such  illegality with respect  thereto ceases to exist,  such  suspension  shall
cease and such affected  Lender shall  similarly  notify  Agent,  Administrative
Agent,  the other Lenders and Borrower and the Alternate  Rate Loan or Base Rate
Loan or Alternate GBP Rate Loan into which such share of the Eurodollar Loans or
Alternate Rate Loans (as applicable) was converted pursuant to this Section 2.13
shall be reconverted to a Eurodollar Loan or Alternate Rate Loan,  respectively,
on the first day of the next succeeding Interest Period.

                  (b)  If   Borrower   fails   to   give  a  valid   Notice   of
Continuation/Conversion  in respect of any portion of a Eurodollar Loan which is
not  repaid  in  accordance  with the terms  hereof  at the end of the  relevant
Interest   Period  in  respect   thereto,   such  portion   shall  be  converted
automatically  into Base  Rate  Loans in the case of Loans  denominated  in U.S.
Dollars or  Alternate  GBP Rate Loans in the case of Loans  denominated  in GBP;
provided   that   if   Borrower   subsequently   gives   a   valid   Notice   of
Continuation/Conversion in respect of such Base Rate Loans or Alternate GBP Rate
Loans,  such Loans shall be converted into  Eurodollar  Loans in accordance with
the requirements for a continuation/conversion under Section 2.5.

                  (c) If  any  Loan  is  converted  to an  Alternate  Rate  Loan
pursuant  to  this  Section   2.13,   Borrower  and  Lenders,   acting   through
Administrative Agent, shall enter into negotiations in good faith with a view to
agreeing upon a substitute  basis for  determining the rate or rates of interest
from time to time  applicable  to such Loan,  which shall be  acceptable to each
Lender,  and the rate or rates so determined shall constitute the Alternate Rate
for that  Loan  from the date of such  conversion.  If,  however,  Borrower  and
Majority  Lenders fail to agree to such substitute basis within thirty (30) days
after such  conversion,  such Loan shall be deemed to have been converted to (i)
in the case of Loans denominated in U.S. Dollars,  a Base Rate Loan, and (ii) in
the case of Loans  denominated  in GBP, an Alternate GBP Rate Loan effective (in
the case of clauses (i) and (ii)) from the date of such conversion.

                  2.14. Eurodollar  Availability.  (a) In the event, and on each
occasion,  that on the day two Business  Days prior to the  commencement  of any
Interest  Period  for any  Eurodollar  Loans,  Administrative  Agent  shall have
determined  (which  determination  shall,  in the absence of manifest  error, be
conclusive and binding upon  Borrower) that U.S.  Dollar or GBP (as the case may
be) deposits in the amount of the principal amount of the Eurodollar Loans which
is to have such  Interest  Period  are not  generally  available  in the  London
interbank market, or that the rate at which such U.S. Dollar or GBP (as the case
may be) deposits are being offered will not  accurately  reflect the cost to any
of the Lenders of making or funding  such  principal  amount of such  Eurodollar
Loans during such Interest  Period,  or that  reasonable  means do not exist for
ascertaining the LIBO Rate, Administrative Agent

       
                                       42

<PAGE>



shall,  as soon as  practicable  thereafter,  give written or telephonic  notice
(which  telephonic  notice  shall  be  followed  immediately  with a  notice  by
facsimile telecopy) of such determination to Agent, the Lenders and Borrower and
(i) such  principal  amount of such  Eurodollar  Loans  shall  automatically  be
converted,  as of  the  last  day of  the  Interest  Period  during  which  such
determination  is made, to Alternate  Rate Loans subject to the last sentence of
this  paragraph  and (ii) any  request by  Borrower  for such  Eurodollar  Loans
pursuant  to Section 2.3 hereof  shall  thereupon,  and until the  circumstances
giving rise to such notice no longer exist (as notified by Administrative  Agent
to Borrower  and the  Lenders),  be deemed a request for the making of Alternate
Rate Loans. If at any time  Administrative  Agent shall have  determined  (which
determination shall, in the absence of manifest error, be conclusive and binding
upon Borrower) that any  contingency  has occurred which  adversely  affects the
London  interbank  market or that any  Requirement  of Law or any  change in any
existing  Requirement  of  Law  or  in  the  interpretation   thereof  or  other
circumstance  affecting  the Lenders or the London  interbank  market  makes the
funding of the Eurodollar Loans  impracticable,  Administrative  Agent shall, as
soon as  practicable  thereafter,  give  written  or  telephonic  notice  (which
telephonic  notice  shall be  followed  immediately  with a notice by  facsimile
telecopy) of such  determination  to Agent, the Lenders and Borrower and (i) the
Eurodollar Loans shall  automatically  be converted,  as of the last day of each
Interest  Period  during  which such  determination  is made and in each case in
respect of the  principal  amount of the  Eurodollar  Loans  having an  Interest
Period  ending on such  date,  to  Alternate  Rate  Loans,  subject  to the last
sentence of this paragraph,  and (ii) any request by Borrower for the Eurodollar
Loans   pursuant  to  Section  2.3  hereof  shall   thereupon,   and  until  the
circumstances  giving  rise to such  notice no  longer  exist  (as  notified  by
Administrative  Agent to Borrower,  Agent and the Lenders),  be deemed a request
for the making of Alternate Rate Loans.  If, in the  circumstances  specified in
this  paragraph or in Section  2.13,  Administrative  Agent  determines  that no
reasonable  alternate  source  of  funding  for  the  Eurodollar  Loans,  or  no
reasonable   basis  for   determining   the  Alternate  Rate,  is  available  or
practicable,  Administrative  Agent shall  promptly so notify the other Lenders,
Agent and Borrower  thereof and any notice of borrowing  under Section 2.3 shall
be deemed  rescinded  and each  principal  amount of the  Eurodollar  Loans,  if
outstanding,  having an Interest Period then current, together with all interest
thereon,  shall be due and payable by  Borrower on the last day of the  Interest
Period then applicable to it.

                  (c) If  any  Loan  is  converted  to an  Alternate  Rate  Loan
pursuant  to  this  Section   2.14,   Borrower  and  Lenders,   acting   through
Administrative Agent, shall enter into negotiations in good faith with a view to
agreeing upon a substitute  basis for  determining the rate or rates of interest
from time to time  applicable  to such Loan,  which shall be  acceptable to each
Lender,  and the rate or rates so determined shall constitute the Alternate Rate
for that  Loan  from the date of such  conversion.  If,  however,  Borrower  and
Majority  Lenders fail to agree to such substitute basis within thirty (30) days
after such  conversion,  such Loan shall be deemed to have been converted to (i)
in the case of Loans denominated in U.S. Dollars,  a Base Rate Loan, and (ii) in
the case of Loans denominated in GBP, an Alternate GBP Rate Loan,  effective (in
the case of clauses (i) and (ii)) from the date of such conversion.

                  2.15.  Indemnities.  Borrower  shall  indemnify each Lender on
demand for, from and against any actual loss (including, without limitation, any
loss of anticipated  profits) or expense  (including but not limited to any loss
or expense  sustained or incurred in  liquidating  or  employing or  redeploying
deposits from third parties acquired to effect or

       
                                       43

<PAGE>



maintain  any Loan or any  portion  thereof)  which such Lender or its branch or
Affiliate may sustain or incur as a consequence of (i) any default in payment or
prepayment  of the  principal  amount  of any  Loan or any  portion  thereof  or
interest accrued thereon,  as and when due and payable (at the due date thereof,
by irrevocable notice of payment or prepayment,  or otherwise),  (ii) the effect
of the  occurrence  of any Event of Default upon any Loan,  (iii) the payment or
prepayment of any principal  amount of any Loan or the conversion of any portion
of any  Eurodollar  Loan to  Alternate  Rate Loans or Base Rate Loans on any day
other than the last day of an Interest  Period or the payment of any interest on
such Loan, or portion thereof,  on a day other than an Interest Payment Date for
the Loan or (iv) any failure of  Borrower  to accept or make a borrowing  of the
Loans or continue or convert a Loan after delivery of a notice requesting a Loan
under Section 2.3 or, as the case may be, a notice  requesting a continuation or
conversion  under  Section  2.5 or any failure by Borrower to satisfy any of the
conditions precedent to the making of Loans hereunder after it has requested the
borrowing  thereof (other than any such conditions that are waived in accordance
with the  provisions  hereof).  The  determination  of each Lender of any amount
payable  under this Section  2.15 shall,  in the absence of manifest  error,  be
conclusive and binding upon Borrower.

                  2.16 Eligible  Mortgages  and Eligible  Properties No Mortgage
Interest  shall be an Eligible  Mortgage  and no  Property  shall be an Eligible
Property unless,  on any relevant date, there has been no MAC in respect of such
(i) Property (or any Operator or Credit Support  Obligor for the Lease thereof),
or (ii) Mortgaged  Property (or any Mortgagor or Credit Support  Obligor for the
Mortgage Interest  Agreements in respect  thereof),  in each case since December
31, 1995 or, if later,  the date on which  Borrower  or any of its  Subsidiaries
acquired an interest in such Property or Mortgaged  Property other than, in each
case, a MAC which has ceased to be in effect;  provided that for the purposes of
this  Section  2.16,  failure to comply with  clause  (ii) of Section  5.5(a) in
connection with an Eligible  Property or an Eligible Mortgage shall be deemed to
constitute a MAC in respect of such Eligible Property or Eligible Mortgage.


                           SECTION 3.  REPRESENTATIONS AND WARRANTIES

                  In order to induce the  Lenders  to enter into this  Agreement
and to make the Loans herein provided for, Borrower hereby covenants, represents
and warrants to Agent, Administrative Agent and each Lender that:

                  3.1.  Financial  Condition.  The balance sheet of Borrower and
its Subsidiaries (if any) as at December 31, 1991,  December 31, 1992,  December
31, 1993,  December 31, 1994 and December 31, 1995 and the related  consolidated
statements of income,  stockholders'  equity and cash flows for the fiscal years
ended on such dates, certified by Ernst & Young, copies of which have heretofore
been  furnished  to Agent,  are  complete  and correct  and  present  fairly the
financial  condition of Borrower and its Subsidiaries (if any) on a consolidated
basis as at such dates, and  stockholders'  equity and cash flows for the fiscal
years then ended. All such financial statements, including the related schedules
and  notes  thereto,   have  been  prepared  in  accordance  with  GAAP  applied
consistently  throughout  the  periods  involved  (except  as  approved  by such
accountants  or  Responsible  Officer,  as the  case  may be,  and as  disclosed
therein). Borrower and its Subsidiaries have no material Contingent

       
                                       44

payment of which  could  result in a Default  or Event of  Default  nor have any
Common  Shares,  Preferred  Shares or other equity  securities  of Borrower been
redeemed,  retired, purchased or otherwise acquired for value by Borrower or any
of its Subsidiaries.

                  3.3. Existence;  Compliance with Law. Borrower and each of its

respective  jurisdiction of incorporation,  (b) has full power and authority and
the legal right to own its  property,  to lease (as lessee) the property that it

jurisdiction  where its  ownership  or lease of  property  or the conduct of its
business  require  such  qualification,  and  (d)  is  in  compliance  with  all
Requirements of Law except to the extent that the failure to comply therewith is
not reasonably likely to have, in the aggregate, a Material Adverse Effect.

                  3.4. Operator,  Advisor,  Credit Support Obligors;  Compliance
with Law.

                  (a) To the best  knowledge  of  Borrower,  each  Operator  and

jurisdiction  where its  ownership,  lease (or  sublease)  or  operation  of any
Facility  requires  such  qualification,  and  (iii) is in  compliance  with all
Requirements  of Law applicable to the Facilities  operated by it, or applicable
to the  operation  thereof  except  to the  extent  that the  failure  to comply
therewith is not reasonably likely to have, in the aggregate, a Material Adverse
Effect.

                  (b) To the best  knowledge  of  Borrower,  the Advisor (i) has
full power and  authority and legal right to conduct the business in which it is
presently engaged and to perform its obligations  under the Advisory  Agreement,

Obligors  (i) have full  power and  authority  and legal  right to  conduct  the
business in which they are presently  engaged and to perform  their  obligations
under the Credit Support Agreements to which they

<PAGE>



are parties, and (ii) are in compliance with all Requirements of Law, except, in
the case of  clauses  (i) and (ii),  to the  extent  that the  failure to comply
therewith is not reasonably likely to have, in the aggregate, a Material Adverse
Effect.

                  3.5. Power; Authorization;  Enforceable Obligations.  Borrower
and each of its  Subsidiaries has the power and authority and the legal right to
make, deliver and perform each of the Loan Documents to which it is a party and,
in the case of  Borrower,  to  borrow  hereunder;  and  Borrower  has  taken all
necessary  action  to  authorize  the  borrowings  hereunder,  on the  terms and
conditions of the Loan Documents,  and Borrower and each of its Subsidiaries has
taken all necessary action to authorize the execution,  delivery and performance
of  each  of  the  Loan  Documents  to  which  it  is a  party.  No  consent  or
authorization of, filing with, or other act by or in respect of any Governmental
Authority is required in connection  with the  borrowings  hereunder or with the
execution,  delivery,  performance,  validity  or  enforceability  of  the  Loan
Documents.  This  Agreement has been, and each other Loan Document will be, duly
executed and delivered on behalf of Borrower and each of its Subsidiaries  which
is a party thereto and this Agreement constitutes,  and each other Loan Document
when  executed  and  delivered  will  constitute,  a legal,  valid  and  binding
obligation  of Borrower and each of its  Subsidiaries  which is a party  thereto
enforceable  against  Borrower  and  each of its  Subsidiaries  which is a party
thereto in accordance with its terms, except as enforceability may be limited by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting the enforcement of creditors' rights generally.

                  3.6. No Legal Bar. The execution,  delivery and performance of
this Agreement and the other Loan  Documents,  the borrowings  hereunder and the
use of the  proceeds  thereof,  will not violate any  Requirement  of Law or any
Contractual  Obligation  of  Borrower or any of its  Subsidiaries,  and will not
result in, or require,  the creation or  imposition  of any Lien on any of their
respective  properties  or  revenues  pursuant  to  any  Requirement  of  Law or
Contractual Obligation.

                  3.7. No Material Litigation.  No litigation,  investigation or
proceeding of or before any arbitrator or Governmental  Authority is pending or,
to the best knowledge and belief of Borrower,  threatened by or against Borrower
or any of its  Subsidiaries  or against any of their  respective  properties  or
revenues or, to the best knowledge and belief of Borrower,  by or against any of
the Operators and Mortgagors or against any of their  respective  properties (a)
with respect to this  Agreement  or the other Loan  Documents,  the Leases,  the
Mortgage Interest Agreements,  or any of the transactions contemplated hereby or
thereby,  or (b) relating to the  Properties,  the  Mortgaged  Properties or the
ownership  or the  operation  thereof  or the  conduct  of  business  thereon as
presently  conducted,  which, in the case of (a) or (b), is reasonably likely to
have, in the aggregate, a Material Adverse Effect.

                  3.8. No Default.  Neither Borrower nor any of its Subsidiaries
is in default under or with respect to any Contractual Obligation in any respect
which could have a Material  Adverse Effect.  No Default or Event of Default has
occurred and is continuing.

                  3.9.  Ownership of Mortgage Interests and Property; Liens.

                  (a) In the case of a Mortgage Interest, Borrower or one of its
Subsidiaries has good record, marketable and indefeasible title to such Mortgage
Interest. In the case of a Property which is a Fee Interest,  Borrower or one of
its  Subsidiaries  has good  record,  marketable  and  indefeasible  fee  simple
absolute  title  to such Fee  Interest.  In the  case of a  Property  which is a
Leasehold  Interest,  Borrower  or one of its  Subsidiaries  has good record and
marketable title to such Leasehold Interest.  In the case of a Mortgage Interest
in respect of which all or any part of the Mortgaged  Property is a fee interest
in land and/or buildings,  structures,  improvements and fixtures, the Mortgagor
with  respect  to such  Mortgaged  Property  has  good  record,  marketable  and
indefeasible fee simple absolute title to such Mortgaged  Property.  In the case
of a Mortgage  Interest  in  respect  of which all or any part of the  Mortgaged
Property is a leasehold  estate,  the Mortgagor  with respect to such  Mortgaged
Property has good record and marketable title to such leasehold  estate. In each
of the cases  described in this Section 3.9,  such title shall be free and clear
of all Liens and other matters affecting title except for such other matters not
reasonably likely to have, in the aggregate, a Material Adverse Effect.

                  (b) The buildings,  structures, and other improvements located
on each Facility are in good operating  condition and repair  (ordinary wear and
tear which are not such as to materially and adversely  affect the operations of
the business conducted thereon,  excepted),  free of any material  structural or
engineering  defects  known to Borrower or any of its  Subsidiaries  on the date
hereof and are suitable for their present uses, subject to such exceptions which
are not reasonably likely to have, in the aggregate, a Material Adverse Effect.

                  (c) All water,  sewer, gas,  electricity,  telephone and other
utilities serving each Facility are supplied directly to such Facility by public
utilities and enter such Facility  through  adjoining public streets or, if they
pass through  adjoining  private  land,  do so in  accordance  with valid public
easements which inure to the benefit of Borrower or one of its  Subsidiaries (in
the case of a Facility in which Borrower or such  Subsidiary has a Fee Interest)
or a mortgagor's  or  beneficiary's  benefit (in the case of a Facility in which
Borrower or such Subsidiary is a mortgagor or beneficiary,  as applicable,  of a
loan  secured  in whole  or in part by a Lien on a  Facility),  subject  to such
exceptions which are not reasonably likely to have, in the aggregate, a Material
Adverse Effect. All of such utilities are presently  installed and operating and
are in good  and  safe  condition,  subject  to such  exceptions  which  are not
reasonably  likely to have, in the aggregate,  a Material  Adverse  Effect.  All
material  assessments  for public  improvements  that have been made against the
Facilities  have  been  paid or  provided  for,  except  that in the case of any
assessments  that are payable in  installments,  all  installments due as of the
date hereof have been paid or provided for, subject to such exceptions which are
not reasonably likely to have, in the aggregate, a Material Adverse Effect.

                  (d) None of Borrower or any of its Subsidiaries or to the best
knowledge and belief of Borrower,  the Operators  and  Mortgagors,  has received
notice of any pending,  threatened or  contemplated  condemnation  proceeding or
similar taking affecting the Facilities,  or any portion thereof, or any sale or
other  disposition  of  the  Facilities  or  any  portion  thereof  in  lieu  of
condemnation or similar taking, in each case, subject to such

       
                                       47

<PAGE>



exceptions which are not reasonably likely to have, in the aggregate, a Material
Adverse Effect.

                  (e)  All  Real   Property   Permits   from  all   Governmental
Authorities having jurisdiction over the Facilities or any portion thereof,  the
absence  of  which  could  materially  impair  the use of any  Facility  for the
purposes for which it is currently  used,  and from all insurance  companies and
fire rating and similar boards and organizations required to have been issued to
Borrower or any of its  Subsidiaries  or any  Operators  and  Mortgagors of such
Facility,  as the case may be, to enable such Facility or any portion thereof to
be lawfully  occupied and used as currently so occupied or used have been issued
and are in full  force and  effect,  subject  to such  exceptions  which are not
reasonably likely to have, in the aggregate,  a Material Adverse Effect. Neither
Borrower nor any of its  Subsidiaries  has received or been  informed by a third
party, including the Operators and Mortgagors of the Facilities,  of the receipt
by it of any notice from any Governmental Authority having jurisdiction over the
Facilities or any portion  thereof or from any insurance  company or fire rating
or  similar  board  or  organization   threatening  a  suspension,   revocation,
modification  or  cancellation  of any Real  Property  Permit,  subject  to such
exceptions which are not reasonably likely to have, in the aggregate, a Material
Adverse Effect.

                  (f)  Each of the  Leases,  Mortgage  Interest  Agreements  and
Credit  Support  Agreements   relating  to  Properties  and  Mortgage  Interests
(including  Properties which are not Eligible  Properties and Mortgage Interests
which are not Eligible  Mortgages)  is in full force and effect and is a legally
valid and  binding  obligation  of Borrower  or its  Subsidiaries  and the other
parties thereto,  subject to such exceptions which are not reasonably  likely to
have, in the aggregate,  a Material Adverse Effect.  Neither Borrower nor any of
its  Subsidiaries  has  mortgaged,  pledged or otherwise  encumbered  any of the
Leases or Mortgage Interest  Agreements or its right to obtain rental,  interest
or other  payments  thereunder  except for the Liens  permitted  by Section 6.9.
Neither  Borrower nor any of its  Subsidiaries  has collected any rents becoming
due under any Lease more than 30 days in advance  (except (i) an amount equal to
one  month's  instalment  of rent  under a Lease  or (ii) in the case of a lease
acquired  from Host  Marriott  Corporation  and its  Affiliates  pursuant to the
transaction (or one on  substantially  similar terms)  described in the Form S-3
Registration  Statement of Borrower filed with the Commission on March 29, 1994,
an amount  equal to no more than  three  months'  instalment  of rent under such
lease).  All rent and other sums and charges  payable by any Operator under each
Lease to which it is a party are  current,  no notice of default or  termination
under any such  Lease is  outstanding,  no  termination  event or  condition  or
uncured default on the part of an Operator exists under any Lease,  and no event
of default has occurred which, with the giving of notice or the lapse of time or
both,  would  constitute  such a default or  termination  event or  condition or
uncured default on the part of Borrower or its Subsidiaries or the Operators (as
the case may be), subject to such exceptions which are not reasonably  likely to
have,  in the  aggregate,  a  Material  Adverse  Effect.  Except as set forth on
Schedule 6, all payments required from any Mortgagor under any Mortgage Interest
Agreement  to  which  it is a  party  are  current,  no  notice  of  default  or
acceleration  under any such  Mortgage  Interest  Agreement is  outstanding,  no
default or  condition  or uncured  default on the part of the  Mortgagor  exists
under any  Mortgage  Interest  Agreement,  and no event of default has  occurred
which,  with the giving of notice or the lapse of time or both, would constitute
such a default or termination  event or condition or uncured default on the part
of the Mortgagor,  subject to such exceptions which are not reasonably likely to
have, in the

       
                                       48

<PAGE>



aggregate,  a Material  Adverse  Effect.  All payments  required from any Credit
Support  Obligor in respect of any Credit  Support  Agreement for the Lease of a
Property  or for a  Mortgage  Interest  are  current,  no notice of  default  or
acceleration  under any such Credit  Support  Agreement is  outstanding,  and no
default or  condition  or uncured  default  on the part of such  Credit  Support
Obligor  exists  under  any  such  Credit  Support  Agreement,  subject  to such
exceptions which are not reasonably likely to have, in the aggregate, a Material
Adverse Effect.  As to all of the Leases,  Borrower and each of its Subsidiaries
has performed all of its repair and maintenance obligations (if any) and, to the
best  knowledge and belief of Borrower,  each Operator and Mortgagor  under each
Lease and  Mortgage to which it is a party has  performed  all of its repair and
maintenance  obligations,  subject to such  exceptions  which are not reasonably
likely to have, in the aggregate, a Material Adverse Effect.

                  (g) Borrower and each of its  Subsidiaries has good record and
marketable  title in fee simple to or valid  mortgage  interests in all its real
property,  other  than the  Properties  and  Mortgaged  Properties,  as to which
Borrower has made the representation set forth in subsection (a) of this Section
3.9, and good title to all its other  property  other than the  Properties,  and
none of such  property is subject to any Lien for borrowed  money as of the date
hereof, except for Liens permitted by Section 6.9.

                  3.10. No Burdensome Restrictions. No Contractual Obligation of
Borrower or any of its Subsidiaries or, to Borrower's best knowledge and belief,
of any of the Operators and Mortgagors and no Requirement of Law currently has a
Material Adverse Effect, or insofar as Borrower may reasonably  foresee may have
a Material Adverse Effect.

                  3.11.  Taxes.  Borrower and each of its Subsidiaries has filed
or caused to be filed all tax returns which to the best  knowledge and belief of
Borrower are  required to be filed,  and has paid or caused to be paid all taxes
shown to be due and payable on said returns or on any  assessments  made against
it or any of its property and all other taxes,  fees or other charges imposed on
it or any of its property by any  Governmental  Authority  (other than those the
amount or  validity  of which is  currently  being  contested  in good  faith by
appropriate  proceedings  and with respect to which reserves in conformity  with
GAAP have been provided on the books of Borrower or such Subsidiary); and no tax
Liens have been filed and, to the  knowledge  of  Borrower,  no claims are being
asserted with respect to any such taxes, fees or other charges.

                  3.12.  Federal  Regulations.  Neither  Borrower nor any of its
Subsidiaries  is engaged  and nor will it engage,  principally  or as one of its
important  activities,  in the business of  extending  credit for the purpose of
"purchasing" or "carrying" any "margin stock" within the respective  meanings of
each of the quoted  terms under  Regulation  U of the Board of  Governors of the
Federal Reserve System as now and from time to time hereafter in effect. No part
of the  proceeds  of the  Loans  hereunder  will be  used  for  "purchasing"  or
"carrying"  "margin stock" as so defined or for any purpose which  violates,  or
which would be  inconsistent  with,  the  provisions of the  Regulations of such
Board of  Governors.  If requested by Agent,  Borrower will furnish to Agent and
each Lender a statement in conformity  with the  requirements of Federal Reserve
Form U-1 referred to in said Regulation U to the foregoing effect.

                  3.13. Employees.  Neither Borrower nor any of its Subsidiaries
has any

       
                                       49

<PAGE>



employees and none of them has ever engaged any employees.

                  3.14.  ERISA. No ERISA Affiliate has been, since July 1, 1974,
an  "employer",  as defined in Section 3(5) of ERISA,  in respect of any Plan or
making contributions to any Multiemployer Plan.

                  3.15. Status as REIT. Borrower is organized in conformity with
the requirements for  qualification as a real estate  investment trust under the
Code.  Borrower's  failure to elect to be treated  as a real  estate  investment
trust under the Code for its fiscal year ended December 31, 1986 has not had and
will  not  have  any  Material  Adverse  Effect.  Borrower  has  met  all of the
requirements for  qualification as a real estate investment trust under the Code
for its fiscal  years  ended  December  31,  1991,  1992,  1993,  1994 and 1995.
Borrower  is in a position  to qualify  for its  current  fiscal  year as a real
estate  investment  trust under the Code and its  proposed  methods of operation
will enable it to so qualify.

                  3.16. Restrictions on Incurring Indebtedness. Neither Borrower
nor  any  of  its  Subsidiaries  is (a) an  "investment  company"  or a  company
"controlled"  by an "investment  company,"  within the meaning of the Investment
Company Act of 1940,  as amended,  or (b) a "holding  company" as defined in, or
otherwise subject to, regulation under the Public Utility Holding Company Act of
1935.  Neither  Borrower nor any of its  Subsidiaries  is subject to  regulation
under any federal or state  statute or  regulation  which  limits its ability to
incur the indebtedness or give the guaranties described in this Agreement.

                  3.17. Subsidiaries.  Set forth on Schedule 4 annexed hereto is
a complete and accurate list of all of Borrower's Subsidiaries showing as of the
date hereof (as to each Subsidiary) the jurisdiction of its  incorporation,  the
number of shares of each  class of  capital  stock  authorized,  and the  number
outstanding,  and the  percentage  of each  class  of  capital  stock  owned  by
Borrower,  all of which capital stock is owned free and clear of all Liens;  all
of the issued and outstanding  shares of capital stock of such Subsidiaries have
been duly authorized and validly issued and are fully paid and non-assessable.

                  3.18. Compliance with Environmental Laws. Borrower and each of
its Subsidiaries and, to the best knowledge of Borrower,  each Operator and each
Mortgagor of the Facilities is in compliance with all applicable statutes, laws,
rules,  regulations  and  orders of all  Governmental  Authorities  relating  to
environmental  protection,  pollution  control and Hazardous  Materials and with
respect to the conduct of its  business  and the  ownership  of its  properties,
except for such  noncompliance  which would not result in  imposition  of Liens,
fines,  penalties,  injunctive relief or other civil or criminal liabilities and
which, in the aggregate, could not have a Material Adverse Effect.

                  3.19. Pollution;  Hazardous Materials.  In connection with the
acquisition  and  ownership  of its  interests  in the  Properties  and Mortgage
Interests,  Borrower and each of its  Subsidiaries has made and will continue to
make such inquiries, and has and will continue to cause such testing, surveying,
inspection  or other  action,  with respect to each  Facility as is necessary or
desirable in connection  with Hazardous  Materials which might be present in the
air,  soil,  surface  water or  groundwater  at such  Facility.  Except for such
exceptions which are not reasonably likely to have, in the aggregate, a Material
Adverse Effect, there are not, and,

       
                                       50

<PAGE>



to the knowledge of Borrower after diligent  inquiry,  were not previously,  any
Hazardous  Materials  present in the air, soil,  surface water or groundwater at
any Facility and no Hazardous Materials (except Hazardous  Materials  maintained
in  accordance  with all  Requirements  of Law and  necessary  for the  business
operations of any such Facility as a health care  facility,  including,  without
limitation,  petroleum used for heating oil and certain medications) are used in
the operation of any  Facility.  Borrower is not aware of any claim or notice of
violation,  alleged violation,  noncompliance,  liability or potential liability
relating  to any  Facility  nor any  judicial  proceedings  or  governmental  or
administrative actions pending or, to the knowledge of Borrower,  threatened, to
which Borrower or any of its  Subsidiaries  would be named a party in connection
with any Facility which, if adversely determined,  would be reasonably likely to
result in a Material Adverse Effect.

                  3.20.  Securities  Laws. None of the Common Shares,  Preferred
Shares or other  equity  securities  of Borrower has been issued in violation of
the Securities Act of 1933, as amended, or the securities or "blue sky" or other
applicable laws or regulations of any applicable jurisdiction.

                  3.21. Declaration of Trust, By-Laws,  Advisory Contract,  etc.
The copies of the  Declaration of Trust and by-laws of Borrower and the Advisory
Agreement  which have been  furnished  to Agent are true,  correct and  complete
copies thereof as in effect on the date of this Agreement.

                  3.22.  Disclosures.  The financial  statements  referred to in
Section 3.1 do not, nor does this Agreement,  the other Loan  Documents,  or any
other written  statement  furnished by or on behalf of Borrower to any Lender in
connection with the  transactions  contemplated  hereby or thereby,  contain any
untrue  statement of a material fact or omit a material  fact  necessary to make
the statement contained therein or herein not misleading.

                  3.23.  Medicare  and Medicaid  Certification.  Subject to such
exceptions which, in the aggregate, are not reasonably likely to have a Material
Adverse   Effect,   to  the  best   knowledge  of  Borrower   after   reasonable
investigation,  each  Operator  with respect to each of the  Properties  that it
operates,  and each Mortgagor  with respect to each of the Mortgaged  Properties
that it owns,  (a) is validly  licensed  under  applicable  law to operate  such
Property  or  Mortgaged  Property  and to conduct  the  business  in which it is
currently  engaged,  (b)  has  received  any  applicable  certificate  of  need,
determination  of need or similar  approval,  and any amendments or supplements,
and such  approvals  are in full force and  effect,  (c)  (except in the case of
non-healthcare  Properties  and Mortgaged  Properties,  United  Kingdom  located
Properties or Mortgaged  Properties or otherwise where participation in Medicare
or Medicaid is deemed  undesirable  in the reasonable  business  judgment of the
Operator or Mortgagor)  is validly  certified or approved for  participation  in
Medicare and Medicaid by the applicable  federal and state  authorities and is a
party to provider  agreements with respect to its  participation in Medicare and
Medicaid,  which provider  agreements are in full force and effect, in each case
only to the extent that such  Property or  Mortgaged  Property is of a character
eligible for participation in Medicare or Medicaid,  and (d) no proceedings have
been  initiated  or  notices  issued  to  suspend  or revoke  any such  license,
approval,  certification or provider agreement, except for notices of deficiency
which are issued and corrected in the ordinary course of business.

                  3.24. Offering, Etc., of Securities.  Neither Borrower nor any
agent with the authority of Borrower has offered any  securities  similar to the
Notes,  nor  solicited any offer to buy any such  securities,  in a manner which
would  render  the  offering,  sale or  issuance  of the  Notes  subject  to the
registration requirements of the Securities Act of 1933, as amended.


                  SECTION 4.  CONDITIONS PRECEDENT

                           principal)  accrued or owed under the  Existing  Loan
                           Agreement, whether or not presently due and payable.

                  (a)  Representations  and Warranties.  The representations and

real property, health care or retirement facilities to the effect that, or Agent
shall  otherwise  in good faith have  determined  that,  facts or  circumstances
exist, or changes in market conditions have occurred, as a result of which there
exists a reasonable  possibility that Appraisals of the Eligible  Properties and
Mortgaged Properties covered by Eligible Mortgages, might result in an aggregate
valuation  thereof  reflecting a material loss of value as compared to the value
thereof indicated in the certificate of a Responsible Officer delivered to Agent
pursuant to Section 4.1(j) or 4.2(h), or (ii) an Event of Default has occurred.

requested  by  Agent;  provided  that  each  Lender  shall  bear  the  costs  of

record-keeping  requirements relating to the qualification of Borrower as a real
estate  investment  trust as required by the Code and applicable  regulations of
the Department of the Treasury promulgated  thereunder and will properly prepare
and timely  file with the  Internal  Revenue  Service  all  returns  and reports
required  thereby.  Borrower will request from its  shareholders all shareholder
information required by the Code and applicable regulations of the Department of
Treasury promulgated thereunder.

                  5.12.  Indemnification.  Borrower agrees to indemnify,  defend
(with counsel selected by Agent) and hold Agent,  Administrative  Agent, Lenders

connection with the presence,  suspected presence,  release or suspected release
of any Hazardous  Material in the air, soil,  surface water or groundwater at or
from the real property or any portion thereof with respect to a Facility, or any
other  real  property  in  which  Borrower  or any of its  Subsidiaries  has any
interest (all of the foregoing real property  shall be referred to  collectively
as the "Real Property").  Without limiting the generality of the foregoing,  the
indemnification  provided by this Section  shall  specifically  cover (i) costs,
including capital,  operating and maintenance costs, incurred in connection with
any  investigation  or monitoring of site conditions or any clean-up,  remedial,
removal or restoration work required or performed by any federal, state or local

release,  discharge,  disposal,  dumping,  spilling  or leaking  (accidental  or
otherwise)  onto or from the Property before or after the date of this Agreement
by any Person.

                  5.13.  Changes in GAAP.  Borrower and the Lenders hereby agree
that in the event of a change in GAAP which would cause the financial  covenants
set forth  herein to provide  less  protection  to the  Lenders  than  presently
provided for hereunder,  such financial covenants shall be reset, in good faith,
by the Majority Lenders to maintain the protection to the Lenders  equivalent to
that in place  prior to such change and  Borrower  agrees to execute one or more
amendments to this Agreement to effect such reset.

                  5.14.  Clean-Down Period. If at any date of determination (the
"Trigger Date"), Loans are outstanding in an aggregate principal amount equal to
or greater  than 66- 2/3% of the  Commitments,  Borrower  shall prepay the Loans

                  (b) If Borrower or any of its Subsidiaries  shall agree to any
"negative pledge" or like agreement more restrictive (or otherwise more generous
to its  beneficiaries) in its scope than Section 6.9, then,  without any further
action  being  required,  the  provisions  of  such  agreement  relating  to the
prohibition on Liens shall be deemed incorporated by reference (with appropriate
modifications  as may be  necessary)  into this  Agreement  for the  benefit  of
Lenders.

                  5.16. Currency  Arrangements.  (a) Borrower shall at all times

exchange or similar or analogous  arrangements as are (in Borrower's  reasonable

Subsidiaries than are available in an arm's-length transaction from unaffiliated
third  parties  and  (iii)  if  the  Independent  Trustees  determine  in  their
reasonable good faith judgment that such transaction is in the best interests of
Borrower or such  Subsidiary  based on full disclosure of all relevant facts and
circumstances.

                  6.5.  Subsidiaries.  (a) Without the prior written  consent of

                  6.7. Change in Nature of Business. Make any material change in
the nature of its business as  presently  conducted  (where a "material  change"
shall mean any change in the type of industry  then  invested  in in  accordance
with this Section 6.7, regardless of the amount or size of such new investment);
the business of Borrower and its  Subsidiaries as presently  conducted being the

the IDFA Indebtedness, Indebtedness in the nature of bridge financings described
in the  exception  to  Section  6.8(b)  and  Indebtedness  described  in Section
6.8(c)),  at any time to be greater than 50% of the  aggregate  Allowed Value of
all Eligible Properties and all Eligible Mortgages.

                  (b) Incur any  Indebtedness  unless,  in the case of Borrower,
the earliest date for any payment of principal or other settlement thereof is at
least  three  months  after the  Termination  Date,  except  for (i)  Borrower's
guaranty of the IDFA Indebtedness,  the terms of which Indebtedness  provide for
mandatory  redemption  prior to the  Termination  Date  upon the  occurrence  of
certain extraordinary events, and (ii) Indebtedness of Borrower in the nature of
bridge financings to effect  acquisitions of Fee Interests or Mortgage Interests
by  Borrower so long as the final date for  payment or other  settlement  of all

incurrence or issuance and Borrower promptly commences (and diligently  pursues)
the  refinancing  thereof;  provided  that,  at  any  time  either  after  total
Indebtedness in the nature of bridge financings exceeds $100,000,000 or would as
a result of any proposed further bridge financing exceed $100,000,000,  not less
than thirty days prior to the incurrence or issuance of any additional

       
                                       63

<PAGE>



bridge financing,  Borrower shall provide Lenders with such details of the terms
and conditions  thereof as Lenders (acting through Agent) may reasonably request
(and Borrower shall promptly advise Agent of any subsequent  material changes to
such details),  and if after a review of such details  Majority Lenders (each in
its respective absolute discretion)  determine that no further Loans may be made
and the Termination Date shall be brought forward to a date which is the earlier
of the maturity date for such additional  bridge  Indebtedness and a date eleven
months  after the  incurrence  or issuance  thereof,  then,  effective  upon the
incurrence or issuance of such Indebtedness and without any further action being
required,  no further  Loans shall be made and the  definition  of  "Termination
Date" shall be so amended;  provided that if Majority  Lenders  (acting  through
Agent) have not advised Borrower of such a determination  within fifteen days of
receipt of all such  details as they may have  requested,  then,  subject to the
opportunity to review any subsequent  material  changes to the details  provided
and to make a contrary  determination  based thereon,  Majority Lenders shall be
deemed  not to have made such a  determination  and no change to this  Agreement
shall be effected pursuant to this Section 6.8(b).

its  Subsidiaries,  (ii) Indebtedness of a Person acquired by Borrower or any of
its Subsidiaries or (iii)  Indebtedness to which the assets of a Person acquired
by Borrower or any of its Subsidiaries are subject,  which in the case of any of
clause (i), (ii) or (iii) is outstanding at the time of the relevant acquisition
and remains outstanding following such acquisition, to exceed $50,000,000 at any
time; provided that, in addition to Indebtedness  otherwise permitted under this
Section  6.8(c),  Borrower and Church Creek  Corporation may suffer or permit to
exist the IDFA Indebtedness.

                  (d) In the case of Subsidiaries of Borrower,  suffer or permit
to exist any  Indebtedness,  except for (i)  intercompany  Indebtedness  owed to
Borrower  which is incurred  as the result of the direct or indirect  advance by
Borrower of the  proceeds of Loans and used for  purposes  described  in Section
2.11 and (ii) in the case of Subsidiaries  other than Church Creek  Corporation,
the Contingent Obligations arising from the guarantees given under Section 9 and

on any Facility,  Lease, Mortgage Interest, or Credit Support Agreement,  except
(i) in the case of Borrower,  Liens granted to secure Indebtedness in the nature
of  bridge  financings  (but  not  any  subsequent   refinancing  or  any  other
restructuring of such bridge financing)  permitted under Section 6.8(b), so long
as such Liens are granted only on the properties or interests acquired with such
Indebtedness;  provided that any such property or interest  which is the subject
of such a Lien shall not be an Eligible Property or an Eligible  Mortgage,  (ii)
Permitted  Exceptions,  (iii) with respect to either (A) Properties that are not
Eligible  Properties  or (B) Mortgaged  Properties  that are subject to Mortgage
Interest  Agreements  which are not Eligible  Mortgages only, Liens that are not
created or granted by Borrower or any of its  Subsidiaries,  which Liens, in the
aggregate,  would not be reasonably likely to cause or create a Material Adverse
Effect and (iv) (A) Liens  securing  Indebtedness  permitted  by Section  6.8(c)
(other than the IDFA Indebtedness) so long as neither such Indebtedness nor such
Liens were incurred or granted in  contemplation  of such  acquisition  and such
Liens are  granted  only on the  related  properties  or  interests  acquired by
Borrower or its Subsidiaries

       
                                       64

<PAGE>



and (B) Liens existing on the Effective Date securing the IDFA  Indebtedness and
any Liens in  continuation  thereof or replacement or  substitution  therefor so
long as the  Allowed  Value of the  subject  property or interest is not greater
than the Allowed  Value on the  Effective  Date of the property or interest then
the subject of such  permitted  Liens;  provided  that any  property or interest
which is the subject of a Lien permitted  under this clause (iv) shall not be an
Eligible Property or an Eligible Mortgage.

otherwise modify (a) the Advisory Agreement,  or (b) the Declaration of Trust in
a manner which would be reasonably likely to cause a Material Adverse Effect, in
either case without the prior written consent of Agent.

                  6.13.   Payments   Not  to   Exceed   Appraised   Value.   Pay
consideration  in an amount greater than the Appraised Value for the acquisition

Borrower (and to Agent and/or Administrative Agent, as applicable, to the extent
it is or they  are  not  participating  in the  giving  of  notice)  annul  such
acceleration  and the  consequences  thereof;  provided  that at the  time  such
acceleration is annulled:

other sums

       
                                       68

payable in respect of the Loans and  pursuant to this  Agreement,  the Notes and
each other Loan Document  (except any principal of or interest or premium on the

subsequent Default or Event of Default or impair any right consequent thereon.

                  7.3.  Cooperation by Borrower.  To the extent that it lawfully
may,  Borrower agrees that it will not (and that it will cause its  Subsidiaries
not to) at any time insist  upon or plead,  or in any manner  whatever  claim or
take any  benefit  or  advantage  of any  applicable  present  or  future  stay,
extension or moratorium  law, which may affect  observance or performance of the
provisions of this Agreement or of any Note or any other Loan Document.


                  SECTION 8.  THE AGENTS

                  8.1.  Appointment of Agent and Administrative Agent.

                  (a) Each Lender  hereby  irrevocably  designates  and appoints
Kleinwort Benson as Agent of such Lender and each of Wells Fargo Bank,  National
Association  and the GBP Agent (as defined in the definition of  "Administrative
Agent"), as Administrative Agent of such Lender (with their respective functions
as set  forth in the  definition  of  "Administrative  Agent")  (the  Agent  and
Administrative Agent collectively being the "Loan Agents", and, for the purposes
of Sections 8.1(c), 8.1(g), 8.1(h) and 8.1(l),  Co-Agent shall also be deemed to
be a "Loan  Agent") under this  Agreement  and the Loan  Documents and the other
documents or  instruments  delivered  pursuant to or in  connection  herewith or
therewith and each such Lender hereby  irrevocably  authorizes  each Loan Agent,
for such  Lender,  to take  such  action  on  behalf  of each  Lender  under the
provisions  of the Loan  Documents  and to exercise such powers and perform such
duties as are  expressly  delegated  to such Loan Agent by the terms of the Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding  any provision to the contrary  elsewhere in the Loan Documents,
no Loan  Agent  shall  have any  duties or  responsibilities  other  than  those
expressly set forth in the Loan Documents,  nor any fiduciary  relationship with
any  Lender,  and no implied  covenants,  functions,  responsibilities,  duties,
obligations  or  liabilities  shall be read into the Loan Documents or otherwise
exist against either Loan Agent.

                  (b) Each Loan Agent may  execute  any of its duties  under the
Loan Documents by or through agents or  attorneys-in-fact  and shall be entitled
to advice of counsel  concerning all matters  pertaining to such duties. No Loan
Agent shall be  responsible  for the  negligence  or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

                  (c)  None  of the  Loan  Agents  nor any of  their  respective
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(i) liable for any action lawfully

       
                                       69

<PAGE>



taken  or  omitted  to be  taken  by it  under  or in  connection  with the Loan
Documents  (except  for its gross  negligence  or willful  misconduct),  or (ii)
responsible  in  any  manner  to  any  Lender  for  any  recitals,   statements,
representations or warranties made by Borrower or any of its Subsidiaries or any
other Person  contained in the Loan  Documents  or in any  certificate,  report,
statement  or other  document  referred  to or  provided  for in, or received by
either Loan Agent under or in connection  with, the Loan  Documents  (including,
without  limitation,  any  Appraisal or valuation  or any  certificate  or other
report relating to the value of any Property or any Mortgage  Interest),  or for
the value, validity, effectiveness,  genuineness,  enforceability or sufficiency
of the Loan  Documents or otherwise or for any failure of Borrower or any of its
Subsidiaries  or any other  Person to  perform  its  obligations  under the Loan
Documents.  The Loan Agents shall not be under any  obligation  to any Lender to
ascertain  or to  inquire  as to the  observance  or  performance  of any of the
agreements contained in, or conditions of, the Loan Documents, or to inspect the
properties, books or records of Borrower or any of its Subsidiaries or any other
Person or to insure,  protect or preserve any of the property of Borrower or any
of its Subsidiaries or any other Person.

                  (d) Each Loan Agent shall be  entitled  to rely,  and shall be
fully protected in relying, upon any Note, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message,  statement, order or other document or conversation reasonably believed
by it to be genuine  and correct  and to have been  signed,  sent or made by the
proper  Person or  Persons  and upon  advice  and  statements  of legal  counsel
(including,  without  limitation,  counsel  to  Borrower  or its  Subsidiaries),
independent  accountants  and other  experts  selected by such or the other Loan
Agent.  Each  Loan  Agent  may deem and treat the payee of any Note as the owner
thereof for all purposes  unless a written notice of assignment,  negotiation or
transfer thereof shall have been filed with such Loan Agent.

                  (e) Each Loan  Agent  shall be fully  justified  in failing or
refusing  to take any  action  under the Loan  Documents  unless it shall  first
receive  such  advice  or  concurrence  of  the  Majority  Lenders  as it  deems
appropriate or it shall first be indemnified to its  satisfaction by the Lenders
against any and all  liability and expense which may be incurred by it by reason
of taking or  continuing  to take any such action.  Each Loan Agent shall in all
cases be fully protected in acting, or in refraining from acting, under the Loan
Documents in accordance with a request of the Majority Lenders, and such request
and any action  taken or failure to act pursuant  thereto  shall be binding upon
all the Lenders and all future holders of the Notes.

                  (f) No Loan Agent shall be deemed to have  knowledge or notice
of the occurrence of any Event of Default or event,  act or condition which with
notice or lapse of time, or both, would constitute an Event of Default hereunder
unless such Loan Agent shall have received  notice from the other Loan Agent,  a
Lender or Borrower  referring to this Agreement,  describing such event,  act or
condition  or Event of  Default  and  stating  that such  notice is a "notice of
default". In the event that a Loan Agent receives such a notice, such Loan Agent
shall give prompt notice thereof to the Lenders and (provided such notice is not
received  from the other Loan  Agent) to the other Loan  Agent.  Each Loan Agent
shall take such action  with  respect to the rights and  remedies  given to such
Loan Agent  pursuant to the terms of the Loan  Documents as shall be  reasonably
directed by the  Majority  Lenders;  provided  that,  unless and until such Loan
Agent shall have received such directions, such

       
                                       70

<PAGE>



Loan Agent may (but shall not be obligated to) take such action, or refrain from
taking such  action,  as it shall deem  advisable  in the best  interests of the
Lenders.

                  (g) Each Lender expressly  acknowledges  that none of the Loan
Agents   nor   any   of   their   officers,   directors,    employees,   agents,
attorneys-in-fact or affiliates has made any representations or warranties to it
and that no act by either Loan Agent hereinafter taken or hereinbefore  taken in
connection with the Existing Loan Agreement, including any review of the affairs
of  Borrower  or any of its  Subsidiaries,  shall be  deemed to  constitute  any
representation  or  warranty  by that  Loan  Agent to any  Lender.  Each  Lender
represents to the Loan Agents that it has,  independently  and without  reliance
upon  either Loan Agent or any other  Lender,  and based on such  documents  and
information  as it  has  deemed  appropriate,  made  its  own  appraisal  of and
investigation  into the  business,  operations,  property,  financial  and other
condition and creditworthiness of Borrower and its Subsidiaries,  each Operator,
each  Mortgagor and each Credit  Support  Obligor,  and made its own decision to
make  its  loans  hereunder  and  enter  into  this  Agreement,  and that it has
satisfied itself independently, without reliance on either of the Loan Agents or
any   of   their   respective   officers,    directors,    employees,    agents,
attorneys-in-fact  or  affiliates,  as to the  compliance  of  the  transactions
contemplated  hereby with all legal and  regulatory  requirements  applicable to
such Lender.  Each Lender expressly  acknowledges that its representation in the
previous  sentence shall not be restricted or construed in any way to import any
reliance on either  Loan Agent or any other  Lender as a result of any duties or
other actions which may have been  undertaken by that Loan Agent or other Lender
in connection with the Existing Loan Agreement, and, where such Lender is itself
also a party to the Existing Loan Agreement, that such Lender's decision to make
its Loans hereunder and enter into this Agreement is made  independently  of its
decisions  to enter  into the  Existing  Loan  Agreement  and to make any  loans
thereunder.  Each Lender also represents that it will, independently and without
reliance upon either Loan Agent or any other Lender, and based on such documents
and information as it shall deem  appropriate at the time,  continue to make its
own credit  analysis,  appraisals  and  decisions in taking or not taking action
under this Agreement,  and to make such  investigation  as it deems necessary to
inform  itself as to the  business,  operations,  property,  financial and other
condition and  creditworthiness of Borrower and its Subsidiaries,  any Operator,
any Mortgagor or any Credit  Support  Obligor.  Except for notices,  reports and
other documents  expressly  required to be furnished to the Lenders by that Loan
Agent  hereunder,  neither Loan Agent shall have any duty or  responsibility  to
provide any Lender with any credit or other information concerning the business,
operations,  property,  financial and other  condition or  credit-worthiness  of
Borrower  and its  Subsidiaries  which  may  come  into  its  possession  or the
possession   of   any   of   its   officers,   directors,   employees,   agents,
attorneys-in-fact or affiliates.

                  (h) Each Lender  agrees to  indemnify,  defend  (with  counsel
selected  by each Loan  Agent) and hold each Loan Agent in its  capacity as such
(to the extent not reimbursed by Borrower and without limiting the obligation of
Borrower  to do so),  and such  Loan  Agent's  respective  officers,  directors,
shareholders,  employees and agents,  ratably  according to the  aggregate  loan
percentages set forth opposite its name on Schedule 1 hereto, harmless for, from
and against any and all liabilities,  obligations,  losses, damages,  penalties,
actions,  judgments,  suits,  costs,  expenses  or  disbursements  of  any  kind
whatsoever  which  may at any time  (including  without  limitation  at any time
following  the  payment of the Notes) be imposed  on,  incurred  by or  asserted
against  such  Loan  Agent in any way  relating  to or  arising  out of the Loan
Documents or the transactions contemplated thereby or any action taken or

       
                                       71

<PAGE>



omitted by such Loan Agent  under or in  connection  with any of the  foregoing;
provided  that no Lender  shall be liable for the payment of any portion of such
liabilities,  obligations,  losses,  damages,  penalties,  actions,  judgements,
suits,  costs,  expenses or  disbursements  resulting  primarily  from such Loan
Agent's willful  misconduct or gross negligence.  The agreements in this Section
shall survive the payment of the Notes.

                  (i) Each Loan Agent and its  affiliates  may make loans to and
generally  engage  in  any  kind  of  business  with  Borrower  or  any  of  its
Subsidiaries  as though  such Loan Agent were not a Loan Agent  hereunder.  With
respect  to its pro rata share of the Loan made or  extended  by it and any Note
issued to it, each Loan Agent  shall have the same rights and powers  under this
Agreement  as any Lender and may  exercise the same as though it were not a Loan
Agent.  The terms  "Lender" and  "Lenders"  shall include each Loan Agent in its
individual capacity.

                  (j) A Loan  Agent  may  resign  as Loan  Agent  upon 30  days'
written  notice to the  Lenders.  In the event  that a Loan  Agent  shall  enter
receivership,  then the Lenders  (other than the Lender  which is acting as such
Loan Agent, if applicable) may, by unanimous consent,  remove such Loan Agent as
Loan Agent under this Agreement. If a Loan Agent shall resign as such Loan Agent
under this Agreement or a Loan Agent shall be removed, then the Majority Lenders
shall within 30 days of such  resignation  or removal or, in the absence of such
appointment,  the  resigning or removed  Loan Agent  shall,  appoint a successor
agent for the  Lenders,  whereupon  such  successor  agent shall  succeed to the
rights,  powers  and  duties  of such  Loan  Agent,  and  the  term  "Agent"  or
"Administrative Agent", as applicable, shall mean such successor agent effective
upon its appointment,  and the former Loan Agent's rights,  powers and duties as
Loan Agent shall be terminated,  without any other or further act or deed on the
part of such former Loan Agent or any of the  parties to this  Agreement  or any
holders of the Notes. After any retiring Loan Agent's  resignation  hereunder as
Loan Agent or any Loan Agent's removal, the provisions of this Section 8.1 shall
inure to its benefit as to any actions  taken or omitted to be taken by it while
it was a Loan Agent under this Agreement.

                  (k) Each Lender  agrees to use its best efforts  promptly upon
an officer  responsible for the  administration of this Agreement becoming aware
of any development or other information which may have a Material Adverse Effect
or MAC to notify the other  Lenders of the same.  Each Loan Agent agrees that it
shall promptly deliver to each Lender copies of all notices, demands, statements
and communications  which such Loan Agent gives to Borrower,  except for routine
notices of payment due under the Loan Documents and other miscellaneous notices,
demands, statements and communications, the failure of delivery of which to each
Lender shall not have a material  adverse  effect on any Lender.  The  foregoing
notwithstanding, no Loan Agent shall have any liability to any Lender, nor shall
a cause of action  arise  against any Loan Agent,  as a result of the failure of
such Loan  Agent to  deliver to any Lender  any  notice,  demand,  statement  or
communication  required to be delivered by it under this Section 8.1(k),  except
to the extent such failure is due to the gross  negligence or wilful  misconduct
of such Loan Agent.

                  (l) Each Loan Agent shall  endeavor to exercise  the same care
in  administering  the Loan  Documents as it  exercises  with respect to similar
transactions  in  which  it  is  involved  and  where  no  other  co-lenders  or
participants are involved; provided that the liability of such

       
                                       72

<PAGE>



Loan Agent for failing to do so shall be limited as  provided  in the  preceding
paragraphs of this Section 8.1.

                  (m) Each Lender agrees that, as between it and any Loan Agent,
any Loan  Document or  Appraisal,  or other  report or document  with respect to
which the approval of such Lender is required  hereunder,  sent to it for review
shall be deemed  consented to by it for purposes of any approval  thereof by any
Loan Agent if such Lender does not give to such Loan Agent written notice of its
objection  thereto  within  five  Business  Days  of its  receipt  thereof.  The
foregoing  shall be for the  benefit  of such Loan  Agent  only and shall not be
deemed a consent  under any other  provision of this  Agreement or to confer any
rights on Borrower or any of its Subsidiaries under this Agreement in any manner
whatsoever.


                  SECTION 9.  SUBSIDIARY GUARANTIES

                  9.1      Guaranties.

                  In order to induce the  Lenders  to enter into this  Agreement
and to make the Loans to Borrower  hereunder,  each Subsidiary of Borrower other
than Church Creek Corporation agrees as follows:

                  (a) Each such  Subsidiary of Borrower  hereby  unconditionally
(subject to the next paragraph) and irrevocably  guarantees,  as primary obligor
and not merely as  surety,  the full and  punctual  payment  (whether  at stated
maturity,  upon  acceleration  or  otherwise)  of  the  principal  and  interest
(including, without limitation, interest which, but for the filing of a petition
in bankruptcy with respect to Borrower would accrue hereunder) on all Loans made
to Borrower,  and the full and punctual  payment of all other amounts payable by
Borrower under this Agreement  (including  amounts that would become due but for
the  operation of the automatic  stay under Section  362(a) of the United States
Bankruptcy  Code).  Upon failure by Borrower to pay  punctually any such amount,
each such Subsidiary  shall forthwith on demand pay the amount not so paid as if
that Subsidiary instead of Borrower were expressed to be the principal obligor.

                           The  obligations of each Subsidiary of Borrower under
this  Section 9 shall be  limited  to a maximum  aggregate  amount  equal to the
largest amount that would not render its  obligations  subject to avoidance as a
fraudulent  transfer  or  conveyance  under  Section  548 of the  United  States
Bankruptcy  Code or any applicable  provisions of comparable  state law, in each
case after giving  effect to all other  liabilities  of the relevant  Subsidiary
(contingent or otherwise) that are relevant under those laws.

                           In  order   to   provide   for  just  and   equitable
contribution  among the  Subsidiaries of Borrower,  each such Subsidiary  agrees
that if any other Subsidiary makes payments under this Section 9 in an aggregate
amount  in  excess  of the net  value of the  benefits  received  by such  other
Subsidiary  and its own  Subsidiaries  from  extensions  of  credit  under  this
Agreement,  then the Subsidiary which has made such excess payments shall have a
right of  contribution  against  the other  Subsidiaries  of  Borrower  for such
excess.  However,  this right of contribution shall be subject to Section 9.1(e)
in all respects.


       
                                       73

<PAGE>



                           Each  Subsidiary  of Borrower  acknowledges  that the
giving  by it of this  guarantee  is a  condition  precedent  to the  making  or
maintenance of the Loans to Borrower and also acknowledges that a portion of the
proceeds of the Loans may be advanced to it by  Borrower,  and  accordingly  the
obligations guaranteed are being incurred for, and will inure to, its benefit.

                  (b) The obligations of each  Subsidiary of Borrower  hereunder
shall be unconditional,  irrevocable,  direct and absolute and, without limiting
the generality of the foregoing, shall not be released,  discharged or otherwise
affected by (and, to the fullest extent  permitted by law, each such  Subsidiary
waives its rights in connection with):

                  (i) any extension, increase, renewal, settlement,  compromise,
         waiver or release in respect of any  obligation of Borrower  hereunder,
         by operation of law or otherwise;

                  (ii) any  modification  or amendment of or  supplement to this
         Agreement;

                  (iii) any release, impairment, non-perfection or invalidity of
         any direct or indirect security (if any) for any obligation of Borrower
         under this Agreement;

                  (iv) any change in the trust existence, structure or ownership
         of Borrower,  or any insolvency,  bankruptcy,  reorganization  or other
         similar  proceeding  affecting  Borrower or its assets or any resulting
         release or discharge  of any  obligation  of Borrower  contained in the
         Agreement;

                  (v) the existence of any claim,  set-off or other rights which
         such  Subsidiary may have at any time against  Borrower,  any Lender or
         any other  Person,  whether in  connection  herewith  or any  unrelated
         transactions;  provided that nothing herein shall prevent the assertion
         of any such claim by separate suit or compulsory counterclaim;

                  (vi) any invalidity or unenforceability relating to or against
         Borrower  for  any  reason  of  this  Agreement,  or any  provision  of
         applicable  law or  regulation  purporting  to prohibit  the payment by
         Borrower of the  principal  or interest on any Loan or any other amount
         payable by Borrower under this Agreement; or

                  (vii) any other act or omission to act or delay of any kind by
         Borrower,  any  Lender  or any other  Person or any other  circumstance
         whatsoever  which  might,  but for the  provisions  of this  Section 9,
         constitute  a  legal  or  equitable  discharge  of or  defense  to such
         Subsidiary's obligations hereunder.

                  (c) Each such Subsidiary's  obligations hereunder shall remain
in full force and effect  until this  Agreement  shall have  terminated  and the
principal  and interest on all Loans and all other  amounts  payable by Borrower
hereunder shall have been paid in full. Each such Subsidiary further agrees that
its guarantee hereunder shall continue to be effective or be reinstated,  as the
case may be, if at any time  payments,  or any part thereof,  of principal of or
interest on any  obligation  of  Borrower  is  rescinded  or must  otherwise  be
restored  by Agent  or any  Lender  upon the  bankruptcy  or  reorganization  of
Borrower or otherwise.

<PAGE>



                  (d) Each such Subsidiary irrevocably waives acceptance hereof,
presentment,  demand, protest and any notice not provided for herein, as well as
any  requirement  that at any time any  action  be taken by any  Person  against
Borrower or any other Person.

                  (e) Each Subsidiary  irrevocably  waives any and all rights to
which it may be  entitled,  by operation  of law or  otherwise,  upon making any
payment  hereunder to be subrogated to the rights of the payee against  Borrower
with  respect  to such  payment  or  against  any  direct or  indirect  security
therefor, or otherwise to be reimbursed, indemnified or exonerated by or for the
account of Borrower in respect thereof.

                  10.1  CHOICE OF LAW.  THIS  AGREEMENT  AND THE NOTES  SHALL BE

unless  given in writing by the  Majority  Lenders or as  otherwise  provided in
Section 10.6. No waiver of any such right,  power,  privilege or remedy shall be
deemed a waiver of any other  right,  power,  privilege  or remedy  hereunder or
thereunder.  Every right, power, privilege and remedy given by this Agreement or
by applicable law to Agent,  Administrative Agent or any Lender may be exercised
from  time  to  time  and  as  often  as  may  be  deemed  expedient  by  Agent,
Administrative Agent or any Lender.

                  (c) This  Agreement,  the Notes and the other  Loan  Documents
constitute  the entire  agreement of the parties  relating to the subject matter
hereof  and  thereof  and  there  are no verbal  agreements  relating  hereto or
thereto. Section headings herein shall have no legal effect.

                  (d) This  Agreement,  the Notes and the other  Loan  Documents
(including  all  covenants,   representations,   warranties,   rights,   powers,
privileges  and remedies made or granted  herein or therein)  shall inure to the
benefit of, and be enforceable by, Agent,  Administrative  Agent and each Lender
and their  respective  successors  and assigns,  except as  otherwise  expressly
provided in this Agreement.  Neither  Borrower nor any of its  Subsidiaries  may
directly or indirectly assign or transfer (whether by agreement, by operation of
law or otherwise) any of its rights or  obligations  and  liabilities  hereunder
without the prior written consent of each Lender.  Each of the Lenders may make,
carry or transfer  its pro rata share of the Loans at, to or for the account of,
any of its  branch  offices  or the  office  of one or more  of its  Affiliates.
Further,  each Lender may sell participations in all or any part of its pro rata
share of the Loans or its  Commitments  or any other  interest  herein or in its
Notes to another bank or Person,  or with the prior written consent of Agent and
Borrower (not to be  unreasonably  withheld;  provided that  Borrower's  consent
shall not be  required if an Event of Default has  occurred  and is  continuing)
each  Lender  may assign its rights  and  delegate  its  obligations  under this
Agreement and any of the other Loan Documents and with the prior written consent
of Agent and Borrower (not to be unreasonably withheld; provided that Borrower's
consent  shall  not be  required  if an Event of  Default  has  occurred  and is
continuing) may assign all or any part of its pro rata share of the Loans or its
Commitment or any other interest herein or in its Notes to another bank or other
Person in amounts not less than  $5,000,000 (or any lesser amount in the case of
an  assignment by one Lender to another  Lender) to any one  assignee,  in which
event (i) in the case of an  assignment,  upon notice  thereof by such Lender to
Borrower, Agent and Administrative Agent, the assignee shall have, to the extent
of such assignment  (unless  otherwise  provided  therein),  the same rights and
benefits as it would have if it were such Lender  hereunder  and the holder of a
Note and to such  extent  shall be deemed a "Lender"  for all  purposes  of this
Agreement and the other Loan Documents, and (ii) in the case of a participation,
the  participant  shall not have any rights under this  Agreement or any Note or
any other Loan Document (the participant's rights against such Lender in respect
of such  participation  to be those set forth in the agreement  executed by such
Lender  in favor of the  participant  relating  thereto).  In the case of such a
participation,  the terms of the agreement or  agreements  pursuant to which any
such participation is created shall not confer upon the participant any right to
vote its  interest  as a  participant  in respect of any matter  relating to the
Loans other than (w) the  extension  of the  maturity of any Note or the time of
payment of interest  thereon,  (x) the reduction of the rate of interest payable
hereunder,  (y) the reduction of any other amount  payable  hereunder or (z) the
increase  of  such  participant's  share  of the  relevant  Lender's  Commitment
hereunder.  Each Lender may furnish any information  concerning Borrower and its
Subsidiaries, the

       
                                                        78

Advisor,  any  Operator,  any Mortgagor  and any Credit  Support  Obligor in the
possession  of such  Lender  from  time to time to  assignees  and  participants
(including prospective assignees and participants). In the event that any Lender
shall  assign or sell any of its Notes,  such  Lender  shall at the time of such
assignment  or sale  give  written  notice to  Agent,  Administrative  Agent and
Borrower  of the name and  address of the  assignee  (including  the name of the
account officer if applicable).

                  (e) Each Lender  agrees  that such Lender  shall not assign or
offer to assign interests in its Notes in such a manner which would require that
the Notes be registered under applicable securities laws. Each Lender represents
that it is acquiring its  respective  Note for investment and not with a view to
or for sale in connection  with any  distribution  thereof within the meaning of
the  Securities  Act of 1933, as amended;  provided that the  disposition of the
Notes in accordance with the other  provisions of this Section 10.4 shall at all
times remain within the Lenders' control.

                  (f) This  Agreement  may be executed in any number of separate
counterparts,  each of which shall be deemed an original  and all of which taken
together shall be deemed to constitute one and the same instrument.

                  (g) In the event any one or more of the  provisions  contained
in this  Agreement  or any  Notes or any  other  Loan  Documents  should be held
invalid,  illegal or  unenforceable in any respect,  the validity,  legality and
enforceability of the remaining provisions contained herein or therein shall not
in any way be affected  or  impaired  thereby.  The  parties  shall  endeavor in
good-faith  negotiations  to  replace  the  invalid,  illegal  or  unenforceable
provisions with valid  provisions the economic effect of which comes as close as
possible to that of the invalid, illegal, or unenforceable provisions.

                  10.5 Survival. The obligations of Borrower under Sections 2.6,
2.10, 2.12, 2.13, 2.14, 2.15, 5.12 and 10.7 (and all other  indemnification  and
expense  reimbursement  obligations  of  Borrower  under this  Agreement)  shall
survive the  repayment  of the Loans and the  cancellation  of the Notes and the
termination of the other  obligations of Borrower  hereunder and under the other
Loan  Documents.  All  representations  and warranties made hereunder and in any
document,  certificate or statement  delivered  pursuant hereto or in connection
herewith  shall  survive the  execution  and delivery of this  Agreement and the
Notes and the funding of the Loans.

                  10.6  Amendments and Waivers.  With the written consent of the
Majority Lenders,  Agent and Borrower may, from time to time, enter into written
amendments,  supplements  or  modifications  hereto or to any of the other  Loan
Documents and with the written consent of the Majority Lenders,  Agent on behalf
of the Lenders may execute and deliver to Borrower a written instrument waiving,
on such terms and conditions as Agent may specify in such instrument, any of the
requirements  of this  Agreement or the Notes or any Default or Event of Default
and  its  consequences;  provided  that no such  waiver  and no such  amendment,
supplement or modification  shall (a) extend the maturity of any Note, or reduce
the rate or  extend  the time of  payment  of  interest  thereon,  or  reduce or
postpone  the due date for the  principal  amount  thereof  or any other  amount
payable in  connection  herewith,  or change the amount or terms of any Lender's
Commitment or amend, modify or waive any provision of this Section or reduce the
percentage specified in the definition of Majority

Lenders,  or consent to the  assignment  or  transfer  by Borrower or any of its
Subsidiaries of any of its rights and obligations under this Agreement,  in each
case without the written consent of all the Lenders,  (b) amend, modify or waive
any provision of Section 8 or otherwise  change any of the rights or obligations
of either or both of the Loan Agents under any of the Loan Documents without the
written consent of the affected Loan Agent or Loan Agents (as applicable) at the
time, (c) with respect to Section 6.7, amend,  modify or waive (y) any provision
thereof in a manner which permits  Borrower or any of its  Subsidiaries  to own,
operate,  acquire or fund income producing real property interests or facilities
which  do not  offer  health  care or  related  services  or  rehabilitation  or
retirement services,  or incidental  activities to any of the foregoing,  or (z)
the proviso to Section 6.7, without,  in the case of both clauses (y) and (z) of
this clause (c), the written consent of the Majority  Lenders,  Agent,  Co-Agent
and Borrower (provided that any other type of amendment,  modification or waiver
of Section 6.7 shall only require the written  consent of the Majority  Lenders,
Agent and Borrower) or (d) amend,  modify or waive any provision of this Section
10.6  without the  written  consent of all  Lenders.  In the case of any waiver,
Borrower, Agent, Administrative Agent and the Lenders shall be restored to their
former position and rights  hereunder and under the Outstanding  Notes,  and any
Default  or  Event  of  Default  waived  shall be  deemed  to be  cured  and not
continuing;  but no such waiver shall extend to any  subsequent or other Default
or Event of Default, or impair any right consequent thereon.

                  10.7 Payment of Expenses and Taxes. Borrower agrees (a) to pay
or  reimburse  each of Agent  and  Administrative  Agent on  demand  for all its
out-of-pocket  costs and expenses  incurred in connection with the  development,
preparation and execution of, and any amendment,  supplement or modification to,
this  Agreement,  the Notes  and any other  Loan  Documents  or other  documents
prepared  in  connection  herewith,  and the  consummation  of the  transactions
contemplated hereby and thereby,  including,  without limitation, the reasonable
fees and disbursements of counsel to Agent and Administrative  Agent, (b) to pay
or reimburse each Lender,  Agent and Administrative  Agent on demand for all its
costs and expenses  incurred in connection  with the enforcement or preservation
of any rights under this Agreement,  the Notes, the other Loan Documents and any
such other documents,  or the satisfaction or review of conditions  precedent to
any  borrowing  other than that  occurring  on the  Effective  Date,  including,
without  limitation,  reasonable fees and  disbursements of counsel to Agent and
Administrative  Agent and, in the case of  enforcement  or  preservation  of any
rights under this  Agreement,  counsel to the several  Lenders,  and (c) to pay,
indemnify,  and to hold each Lender,  Agent and  Administrative  Agent and their
respective  officers,  directors,  employees  and agents  harmless for, from and
against,  any and all recording and filing fees and any and all liabilities with
respect  to, or  resulting  from any delay in  paying,  stamp,  excise and other
taxes,  if any,  which may be payable or  determined to be payable in connection
with the execution and delivery of, or consummation or  administration of any of
the transactions  contemplated by, or any amendment,  supplement or modification
of, or any waiver or consent under or in respect of, this Agreement,  the Notes,
the  other  Loan  Documents  and  any  such  other  documents,  and  (d) to pay,
indemnify,  and hold  each  Lender,  Agent  and  Administrative  Agent and their
respective  officers,  directors,  employees  and agents  harmless for, from and
against any and all other liabilities,  obligations, losses, damages, penalties,
actions,  judgments,  suits,  costs,  expenses or  disbursements  of any kind or
nature  whatsoever  with  respect  to  the  execution,  delivery,   enforcement,
performance  and  administration  of,  or in any  other  way  arising  out of or
relating to, this  Agreement,  the Notes,  the other Loan Documents and any such
other documents, including, without limitation, any

       
                                       80

claim resulting or arising out of the presence of Hazardous  Materials in any of
the Properties (all the foregoing, collectively, the "Indemnified Liabilities"),
provided  that  Borrower  shall have no  obligation  hereunder  with  respect to
Indemnified  Liabilities  arising  from (i) the willful  misconduct  of any such
Lender  or (ii)  legal  proceedings  commenced  against  any such  Lender by any
security  holder  or  creditor  thereof  arising  out of and based  upon  rights
afforded any such security holder or creditor solely in its capacity as such.

                  10.8  Adjustments; Setoff.

                  (a) If any Lender (a  "benefitted  Lender")  shall at any time
receive any payment of all or part of its Loan, or interest thereon,  or receive
any collateral in respect  thereof  (whether  voluntarily or  involuntarily,  by
set-off,  pursuant to events or proceedings of the nature  referred to in clause
(g) of Section 7.1, or otherwise) in a greater  proportion than any such payment
to or collateral  received by any other Lender, if any, in respect of such other
Lenders' Loan, or interest  thereon,  such benefitted  Lender shall purchase for
cash from the other  Lenders such portion of each such other  Lender's  Loan, or
shall  provide such other Lenders with the benefits of any such  collateral,  or
the proceeds  thereof,  as shall be necessary to cause such benefitted Lender to
share the excess payment or benefits of such collateral or proceeds ratably with
each of the Lenders;  provided that if all or any portion of such excess payment
or benefits is thereafter  recovered from such benefitted Lender,  such purchase
shall be rescinded,  and the purchase price and benefits returned, to the extent
of such  recovery,  but without  interest.  Borrower  expressly  consents to the
foregoing  arrangements  and agrees that each Lender so  purchasing a portion of
another  Lender's  Loan may exercise all rights of payment  (including,  without
limitation,  rights of set-off) with respect to such portion as fully as if such
Lender were the direct holder of such portion.

                  (b) In  addition  to any rights and  remedies  of the  Lenders
provided  by law,  each Lender  shall have the right,  without  prior  notice to
Borrower,  any such  notice  being  expressly  waived by  Borrower to the extent
permitted by applicable law, upon

                  (i) the filing of a petition  under any of the  provisions  of
         the federal bankruptcy act or amendments thereto, by or against;

                  (ii) the making of an assignment  for the benefit of creditors
         by;

                  (iii) the application for the appointment, or the appointment,
         of any receiver of, or of any of the property of;

                  (iv) the issuance of any execution against any of the property
         of;

                  (v) the  issuance  of a subpoena  or order,  in  supplementary
         proceedings, against or with respect to any of the property of; and/or

                  (vi) or the issuance of a warrant of attachment against any of
         the property of;

Borrower  to set off and apply  against  any  indebtedness,  whether  matured or
unmatured,  of Borrower  to such  Lender,  any amount  owing from such Lender to
Borrower, at or at any time

       
                                       81

<PAGE>



after,  the happening of any of the  above-mentioned  events,  and the aforesaid
right of set off may be exercised by such Lender against Borrower or against any
trustee  in  bankruptcy,  debtor in  possession,  assignee  for the  benefit  of
creditors,  receiver, or execution, judgment or attachment creditor of Borrower,
or against anyone else claiming  through or against  Borrower or such trustee in
bankruptcy,  debtor  in  possession,  assignee  for the  benefit  of  creditors,
receiver,  or execution,  judgment or attachment  creditor,  notwithstanding the
fact that such  right of set off shall not have been  exercised  by such  Lender
prior to the making,  filing or issuance,  or service upon such Lender of, or of
notice  of,  any  such  petition;  assignment  for  the  benefit  of  creditors;
appointment or  application  for the  appointment of a receiver;  or issuance of
execution,  subpoena or order of warrant.  Each Lender agrees promptly to notify
Borrower,  Agent and Administrative Agent after any such set off and application
made by such  Lender,  provided  that the failure to give such notice  shall not
affect the validity of such set off and application. The proceeds of any set off
or  application  pursuant  to this  subsection  (b) of  Section  10.8  shall  be
distributed in accordance with the preceding subsection (a).

                  10.9  NONLIABILITY OF TRUSTEES.  THE DECLARATION OF
TRUST ESTABLISHING BORROWER, DATED OCTOBER 9, 1986, A COPY OF
WHICH,  TOGETHER WITH ALL AMENDMENTS THERETO (THE "DECLARATION"),  IS DULY FILED

                                   SCHEDULE 5
                 Calculation of the Mandatory Liquid Asset Costs
                                for any GBP Loans




(a)      The Mandatory  Liquid Asset Costs for a Loan if  denominated in GBP for
         each Interest Period for that Loan is calculated in accordance with the
         following formula:

                  BY + L(Y-X) + S(Y-Z)%                                PER ANNUM
                  --------------------
                       100 - (B+S)

         where on the day of the application of the formula:

         B        is the percentage of Agent's  eligible  liabilities  which the
                  Bank  of   England   then   requires   Agent   to  hold  on  a
                  non-interest-bearing  deposit  account in accordance  with its
                  cash ratio requirements;

         Y        is the rate at which  GBP  deposits  are  offered  by Agent to
                  leading banks in the London interbank market at or about 11.00
                  A.M. on that day for the relevant period;

         L        is the percentage of eligible  liabilities  which (as a result
                  of the requirements of the Bank of England) Agent maintains as
                  secured  money  with  members of the  London  Discount  Market
                  Association  or in certain  marketable or callable  securities
                  approved by the Bank of England,  which  percentage  shall (in
                  the absence of evidence that any other figure is  appropriate)
                  be conclusively presumed to be 5 per cent.;

         X        is the rate at which  secured  GBP  deposits  may be placed by
                  Agent with members of the London Discount  Market  Association
                  at or about 11.00 A.M. on that day for the relevant period or,
                  if  greater,  the rate at which  GBP bills of  exchange  (of a
                  tenor equal to the duration of the relevant  period)  eligible
                  for  rediscounting at the Bank of England can be discounted in
                  the London Discount Market at or about 11.00 A.M. on that day;

         S        is the percentage for Agent's eligible  liabilities  which the
                  Bank of England  requires Agent to place as a special deposit;
                  and

         Z        is the interest  rate per annum allowed by the Bank of England
                  on special deposits.

(b)      For the purposes of this Schedule:

         (i)      "eligible   liabilities"  and  "special   deposits"  have  the
                  meanings  given  to them at the  time  of  application  of the
                  formula by the Bank of England; and

         (ii)     "relevant period" in relation to each Interest Period means:


       
                                      S5-1

<PAGE>



         (A)      if it is 3 months or less, that Interest Period, or

         (B)      if it is more than 3 months, 3 months.

(c)      In the application of the formula,  B, Y, L, X, S and Z are included in
         the formula as figures and not as  percentages,  e.g. if B=0.5% and Y =
         15%, BY is calculated as 0.5 x 15.

(d)      The formula is applied on the first day of each relevant  period.  Each
         amount is rounded up to the nearest one-sixteenth of one per cent.

(e)      If Agent  determines that a change in  circumstances  has rendered,  or
         will render, the formula inappropriate,  Agent (after consultation with
         the Lenders) shall notify Borrower of the manner in which the Mandatory
         Liquid Asset Costs for such Loans will subsequently be calculated.  The
         manner of  calculation  so notified by Agent  shall,  in the absence of
         manifest error, be binding on Borrower.

         Re:      Third Amended and Restated Revolving Loan Agreement

Ladies and Gentlemen:

         As you have  been  advised,  Health  and  Retirement  Properties  Trust
("HRP"),  the  Borrower  under the Third  Amended and  Restated  Revolving  Loan
Agreement,   dated  as  of  March  15,  1996  (the  "Loan  Agreement"),   issued
US$240,000,000 aggregate principal amount of convertible subordinated debentures
on October 7, 1996.  The  Debentures  consisted of three  series:  US$70,000,000
aggregate principal amount of 7.5% Convertible Subordinated Debentures due 2003,
Series A (the "Series A Debentures");  US$130,000,000 aggregate principal amount
of 7.5% Convertible  Subordinated  Debentures due 2003,  Series B (the "Series B
Debentures"),   and  US$40,000,000  aggregate  principal  of  7.25%  Convertible
Subordinated Debentures,  due 2001 (the "7.25% Debentures").  The Debentures are
subordinate to debt of HRP incurred under the Loan Agreement.

         The  Series A  Debentures  mature  on  October  1,  2003 and the  7.25%
Debentures  mature on  October  1,  2001,  which in each case is more than three
months  after the  Termination  Date (as  defined  in the Loan  Agreement),  and
neither such series of Debentures provides for required principal payments prior
to maturity (other than by reason of an acceleration following default).

         The Series B  Debentures  were  offered and sold  outside of the United
States  pursuant to the  provisions of Regulation S under the  Securities Act of
1933, as amended.  The Series B Debentures  mature on October 1, 2003,  which is
more than three  months  after the  Termination  Date,  and do not  provide  for
required  principal  payments  prior to  maturity  (other  than by  reason of an
acceleration  following  default),  except as follows:  As is customary for debt
offerings  of this type in  offshore  transactions,  the  terms of the  Series B
Debentures provide that if (a) HRP

determines  that the payment of principal  of,  premium,  if any, or interest on
Series B Debentures  in bearer form  ("Bearer  Debentures")  or related  coupons
outside of the United  States would under any United States law or regulation be
subject to a certification, identification or information reporting requirements
with regard to the nationality, residence or identity of the beneficial owner of
Bearer  Debentures  or coupons who is a United  States  alien (other than such a
requirement (i) that would not be applicable to a payment make by the Company or
its paying agent (A) directly to the  beneficial  owner or (B) to any custodian,
nominee or other agent of the beneficial owner, or (ii) that can be satisfied by
the custodian,  nominee or other agent certifying that the beneficial owner is a
United States  alien,  provided in the cases  referred to in clauses  (i)(B) and
(ii) that payment to such a custodian,  nominee or other agent is not  otherwise
subject  to  such   requirement),   and  (b)   either  (i)  the   certification,
identification or information reporting requirement cannot be fully satisfied by
the payment of United States withholding, backup withholding or similar taxes or
(ii) the Company has not agreed to pay additional  amounts that are necessary to
"gross up" payments on the Bearer Debentures for such United States withholding,
backup  withholding  or similar  taxes,  then HRP may be  required to redeem the
Bearer Debentures,  in whole and not in part, at 100% of their principal amount,
plus accrued and unpaid  interest,  less applicable  withholding  taxes plus any
applicable additional payments (the "Contingent Tax Redemption").

         As discussed with the Agent,  HRP requests that for purposes of Section
6.8(b) of the Loan Agreement, "the earliest date for any payment of principal or
other  settlement"  of the Series B Debentures  be deemed to be their October 1,
2003 maturity date, notwithstanding the Contingent Tax Redemption.

         HRP would  appreciate  your  confirmation of its  understanding  as set
forth above.  Such  confirmation  will be considered by HRP to be effective as a
written  consent given  pursuant to Section 10.6 of the Loan  Agreement  and, as
such,  will  be  considered  to be  effective  when  executed,  in one  or  more
counterparts, by the Majority Lenders and the Agent.

                                    Very truly yours,

                                    HEALTH AND RETIREMENT PROPERTIES
                                      TRUST

         2.       Conditions to Effectiveness.

         3.       Representations and Warranties.

         In order to induce  Lenders and Agent to enter into this  Amendment and
to amend the Loan Agreement in the manner provided herein,  Borrower  represents
and warrants to each Lender and Agent that the  following  statements  are true,
correct and complete:


         (a) Borrower has the power and  authority to enter into this  Amendment
and to carry out the  transactions  contemplated by, and perform its obligations
under,   the  Loan   Agreement  (as  amended  by  this  Amendment  the  "Amended
Agreement").

         (b) The execution and delivery of this Amendment and the performance of
the Amended  Agreement have been authorized by all necessary  action on the part
of Borrower.

         (c) The  execution  and delivery by Borrower of this  Amendment and the
performance  by  Borrower  of the  Amended  Agreement  and the  use of  proceeds
thereunder do not violate any  Requirement of Law or  Contractual  Obligation of
Borrower and will not result in, or require,  the creation or  imposition of any
Lien on any of its properties or revenues  pursuant to any Requirement of Law or
Contractual Obligation of Borrower.

         (d) This  Amendment and the Amended  Agreement  have been duly executed
and delivered by Borrower and are the legally valid and binding  obligations  of
Borrower,  enforceable  against  Borrower in  accordance  with their  respective
terms,  except  as  enforceability  may be  limited  by  applicable  bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement
of creditors' rights generally.

         (e) The  representations  and warranties  contained in Section 3 of the

relate to an earlier date, in which case they were true, correct and complete in
all material respects on and as of such earlier date.

         (f) No event has  occurred  and is  continuing  or will result from the
consummation o the transactions  described in or otherwise  contemplated by this
Amendment that would constitute a Default or an Event of Default.

         (g)  The  Declaration  of  Trust,   By-Laws  and  other  organizational
documents of Borrower have not been amended since March 15, 1996, and the copies
thereof  delivered to Lenders  under the Loan  Agreement  are true,  correct and
complete  copies thereof as in effect on the effective date described in Section
2.

         4.       Addition of HUB as Guarantor.

         By execution  and delivery of this  Amendment,  HUB hereby agrees to be

notwithstanding  the conditions to  effectiveness  set forth in this  Amendment,
such Subsidiary  Guarantor is not required by the terms of the Loan Agreement to
consent  to the  amendments  to the Loan  Agreement  effected  pursuant  to this
Amendment  and (b)  nothing in the Loan  Agreement  or this  Amendment  shall be
deemed to  require  the  consent  of such  Subsidiary  Guarantor  to any  future
amendments or waivers to the Loan Agreement.
