PART I
Item 1. Business

The Company. HRPT Properties Trust ("HRP" or the "Company") was
organized on October 9, 1986 as a Maryland real estate investment trust
("REIT"). We invest in income producing real estate, including office buildings
and senior housing properties.

As of December 31, 1998, we owned 230 properties for a total investment
of $3.0 billion (at cost), had mortgage investments in 26 properties aggregating
$69.2 million and had an equity investment representing 8.8% of the outstanding
common shares of Hospitality Properties Trust ("HPT") with an approximate
carrying value of $110.6 million, for total real estate investments of
approximately $3.1 billion. The properties are described in "Business
Developments Since January 1, 1998" and "Properties".

Our  principal  executive  offices  are  located at 400 Centre  Street,
Newton, Massachusetts 02458, and our telephone number is (617) 332-3990.

Investment Policy and Method of Operation. Our investment goals are
current income for distribution to shareholders, capital growth resulting from
appreciation in the residual value of owned properties, and preservation and
protection of shareholders' capital. Our income is derived primarily from rent
and interest payments under our leases and mortgages.

Our day to day operations are conducted by REIT Management & Research,
Inc. ("RMR"), our investment manager. RMR provides investment, management,
property management and administrative services to us. RMR originates and
presents investment opportunities to our Board of Trustees. In evaluating
potential investments, we consider factors such as: the historical and projected
rents received and likely to be received from the property to meet operational
needs and financing obligations and to provide a competitive market return on
our investments; the historic and expected operating expenses, including real
estate taxes, incurred and expected to be incurred at the properties; the
growth, tax and regulatory environments of the market in which the property is
located; the quality, experience, and credit worthiness of the property's
operator and tenants; an appraisal of the property, if available; occupancy and
demand for similar properties in the same or nearby markets; the construction
quality, physical condition and design of the property; the geographic area and
type of property; and the pricing of comparable properties as evidenced by
recent arms length market sales.

Prior to investing in properties, we obtain title commitments or
policies of title insurance insuring that we hold title to or have mortgage
interests in such properties, free of material liens and encumbrances.

Our investments are structured using leases with minimum and/or
additional rent and escalation provisions, loans with fixed or floating rates,
joint ventures and partnerships with affiliated or unaffiliated parties,
commitments or options to purchase interests in real estate, mergers or any
combination of the foregoing that will best suit the particular investment.

In connection with our current bank credit facility, we have agreed to
obtain lender approval before exceeding investment concentrations based on
certain criteria (see "Borrowing Policy"). Among these are that no more than 40%
of our investments be operated by any single tenant or mortgagor and that no new
hotel investments be made. No limits, other than those in connection with our
bank credit facility, have been set on the number of properties in which we will
seek to invest, or on the concentration of investments involving any one
facility or geographical area; however, our Board of Trustees consider
concentration of investments in determining whether to make new or increase
existing investments.

Our Declaration of Trust and operating policies provide that any
investment in facilities owned by us or operated by RMR, persons expressly
permitted under the Declaration of Trust to own more than 8.5% of our shares, or
any company affiliated with any of the foregoing must be approved by a majority
of the Board of Trustees not affiliated with any of the foregoing.

We have in the past considered and may in the future consider, from
time to time, the acquisition of or merger with other companies engaged in the
same business as us; however, we have no present agreements or understandings
concerning any such acquisition or merger.

Borrowing Policy. In addition to the use of equity, we utilize
short-term and long-term borrowings to finance investments. We have a bank
credit facility of $500 million. In February 1999, the bank credit facility was
amended to permit the possible spin-off of our senior housing properties. The
bank credit facility (which is guaranteed by most of our subsidiaries) is used
for acquisition funding on an interim basis until equity or long-term debt is
raised and for working capital and general business purposes. Outstanding
borrowings under the bank credit facility at December 31, 1998 were $100
million.

Our borrowing guidelines established by our Board of Trustees and
covenants in various debt agreements prohibit us from maintaining a debt to
equity ratio of greater than 1 to 1. At December 31, 1998, our debt to equity
ratio was .62 to 1. Our senior unsecured debt also imposes covenants on us which
may limit our ability to borrow. The Declaration of Trust prohibits us from
incurring secured and unsecured indebtedness which in the aggregate exceeds 300%
of our net assets, unless approved by a majority of the Board of Trustees not
affiliated with us. There can be no assurance that debt capital will in the
future be available at reasonable rates to fund our operations or growth.

Business Developments Since January 1, 1998

Investments

During 1998, we acquired 48 office properties and five senior housing
properties for an aggregate amount of $981.6 million and provided improvement
funding totaling $17.2 million to our existing properties.

Financing

During 1998, we sold 25,000,000 common shares in a public offering and
sold 6,977,575 common shares in four offerings to unit investment trusts
sponsored by various investment banks, raising gross proceeds of $612.4 million
(net $580.3 million). Proceeds from these offerings were used to repay amounts
outstanding under our revolving bank credit facility, to purchase real estate
and for general business purposes. In addition, we issued 362,217 common shares
due to the conversion of $6.8 million of our convertible subordinated debentures
and issued 286,400 common shares for the purchase of real estate.

Since January 1, 1998, we have issued the following senior unsecured
fixed rate term notes: $100 million of 6.7% Senior Notes due 2005 issued in
February 1998; $160 million of 6-7/8% Senior Notes due 2002 issued in August
1998; $143 million of 8-1/2% Senior Notes due 2013 issued in November 1998; and
$90 million of 7-7/8% Senior Notes due 2009 in March, 1999. In addition, we
issued $50.0 million of senior unsecured remarketed reset notes which are due in
2007 and bear interest at LIBOR plus a premium. The $532.8 million aggregate net
proceeds from these notes were used to repay amounts then outstanding under our
revolving bank credit facility, to purchase real estate and for general business
purposes.

In April 1998, we increased and extended our unsecured revolving bank
credit facility with a group of banks for which Dresdner Bank AG acts as agent.
The new credit facility permits borrowings of up to $500.0 million, matures in
2002 and bears interest at LIBOR plus a premium. We recognized an extraordinary
loss on the early extinguishment of debt for $2.1 million as a result of the
write-off of deferred financing fees associated with our previous bank credit
facility.

Other Developments

Since January 1, 1998, we disposed of one office property and six
senior housing properties for $39.6 million, including two senior housing
properties for $22.5 million in 1999. During this period, we also received full
repayments for $36.0 million of mortgages secured by ten senior housing
properties, including two senior housing properties for $3.0 million in 1999.

In December 1998, we entered an agreement for the disposition of 12
senior housing properties. The net proceeds of this disposition are expected to
be about $65.0 million, and are subject to seller financing. These transactions
are expected to close within the next 30 to 60 days.

In December 1998, we announced a plan for a possible separate financing
which would include a public offering of common shares of one of our
subsidiaries, Senior Housing Properties Trust ("SNH"), and a distribution to our
shareholders of common shares of that subsidiary. The public offering and
distribution constitute one alternative transaction that we are considering with
respect to financing our senior housing real estate investments. The SNH
transaction as described in the SEC filing is not likely to occur under present
market conditions. At this time, we are considering various alternative
transactions which would reposition our senior housing properties into a
separate publicly owned REIT.

On July 1, 1998, we changed our name from "Health and Retirement
Properties Trust" to "HRPT Properties Trust", reflecting our investment in
commercial office properties as well as senior housing real estate.

The Investment Manager

RMR is a Delaware corporation owned by Gerard M. Martin and Barry M.
Portnoy. RMR's principal executive offices are located at 400 Centre Street,
Newton, Massachusetts 02458, and its telephone number is (617) 332-3990. As of
January 1, 1998, we entered into separate investment advisor and property
management agreements with RMR. RMR provides investment, management, property
management services and administrative services to us. In addition, an affiliate
of RMR also provides garage management services to some of our properties. RMR
also acts as the investment manager to HPT and has other business interests. The
Directors of RMR are Gerard M. Martin, Barry M. Portnoy and David J. Hegarty.
The officers of RMR are David J. Hegarty, President and

3
Secretary,  John G. Murray, Executive Vice President, John Popeo, Treasurer, and
Ajay Saini, John A. Mannix, David Lepore and Thomas M. O'Brien, Vice Presidents.
Gerard M. Martin and Barry M. Portnoy are our managing trustees and David J.
Hegarty, Ajay Saini, John A. Mannix and David M. Lepore are our officers.

Employees

As of March 16, 1999, we had no employees. RMR, which administers our
day-to-day operations, had 177 full-time employees and three active directors as
of that date.

Regulation and Reimbursement

Our tenants and borrowers who operate senior housing properties,
including long-term care facilities, retirement communities and assisted living
centers, must comply with federal, state and local statutes and regulations in
order to operate the properties. The health care industry depends significantly
upon federal and federal/state programs for revenues and, as a result, is
vulnerable to the budgetary policies of both the federal and state governments.

Certificates of Need. Certain of our investments are in senior housing
properties which require certificates of need ("CONs") prior to expansion of
beds or services, certain capital expenditures, and in some states, a change in
ownership. CON requirements are not uniform throughout the United States.
Changes in CON requirements may affect competition, profitability of the
properties and our opportunities for investment in senior housing properties.

Federal and State Regulation and Reimbursement. Our senior housing properties
are affected by a number of federal and state statutes and regulations,
including state licensing laws, laws related to reimbursement of long-term care
facilities under Medicare and Medicaid programs and federal and state anti-fraud
and anti-kickback laws. In order to receive Medicare and Medicaid reimbursement,
our tenants and borrowers who operate long-term care facilities must demonstrate
that the facilities are in substantial compliance with state licensing and
federal certification standards, which include extensive resident care and
physical plant requirements. Federal and state agencies regularly monitor the
quality of care provided and regularly inspect the physical conditions of
long-term care facilities. Medicare and Medicaid laws limit reimbursement for
capital costs and in some circumstances for rental or lease expenses. Under the
Balanced Budget Act of 1997 (Public Law 105-33), (the "BBA"), the federal
Department of Health and Human Services, ("HHS"), has adopted a Medicare
prospective payment system for skilled nursing facilities which includes
capital-related costs and is being phased in over three years beginning July 1,
1998. Many states have adopted Medicaid prospective payment systems. The BBA
also increases states' flexibility in establishing Medicaid rates for nursing
facility services, repeals the Boren Amendment under which Medicaid providers
had the right to challenge the adequacy of Medicaid rates and strengthens the
ability of HHS and the states to exclude providers from the Medicare and
Medicaid programs for health care-related offenses. Reduction in Medicare rates
and Medicaid rates may have a negative effect on some of our tenants or
borrowers and may effect their ability to pay rent or mortgage interest income
to us.

Two federal government studies are currently underway to provide
background information and make recommendations regarding the future regulation
of and the possibility of increased governmental funding for the assisted living
industry. One study is being conducted by the General Accounting Office ("GAO")
for the Senate Special Committee on Aging and is focused upon consumer
protection and quality of care issues. The second study is being conducted by
the HHS's Assistant Secretary for Planning and Evaluation and is expected to
touch upon all aspects of the assisted living industry including quality of care
and financing. A 1998 National Academy for State Health Policy study, which is
part of this second study, found that 22 states had implemented licensing
standards specifically for assisted living and draft rules had been issued in an
additional six states, and predicted that every state will soon have reviewed
their regulations governing residential care settings. These studies are
expected to be completed during 1999. We cannot predict whether these studies
will result in governmental policy changes or new legislation, or what impact
any changes may have. Based upon our analysis of current economic and regulatory
trends, we do not believe that the federal government is likely to have a
material impact upon the current regulatory environment in which the assisted
living industry operates unless it also undertakes expanded funding obligations;
and we do not believe a materially increased financial commitment from the
federal government is presently likely. However, we do anticipate that assisted
living facilities will increasingly be licensed and regulated by the various
states, and that with the absence of federal standards, the states' policies
will continue to vary widely.

HHS's Health Care Financing Administration, ("HCFA"), has begun to
implement an initiative to increase the effectiveness of Medicare/Medicaid
nursing facility survey and enforcement activities by HCFA and the states.
HCFA's initiative follows its July 1998 report to Congress on the effectiveness
of the survey and enforcement system, several March 1999 reports by HCFA's
Office of Inspector General concerning quality of care in nursing homes, a July
1998 GAO report which found inadequate care in a significant proportion of
California nursing

4
homes and March  1999 GAO  reports  which  recommended  that HCFA and the states
strengthen their enforcement activities to ensure that nursing homes maintain
compliance with federal health care standards. In July 1998 and March 1999 the
Senate Special Committee on Aging held hearings on these issues. HCFA plans to
focus survey and enforcement efforts at nursing facilities with repeat
violations of Medicare/Medicaid standards, including chain-operated facilities
with patterns of noncompliance. HCFA also is requiring state agencies to use
enforcement sanctions and remedies more promptly and effectively when
substandard care is identified, and HCFA is increasing its oversight of state
survey agencies. In addition, HCFA has adopted new regulations expanding the
ability of HCFA and the states to impose civil money penalties in instances of
noncompliance. Medicare/Medicaid survey results for each facility are being
posted on the Internet. A newly-enacted federal law prohibits nursing homes
which reduce their Medicaid participation from evicting Medicaid residents.
Federal efforts to target fraud and abuse and kickback violations by Medicare
and Medicaid providers have also increased. An adverse determination concerning
any operator's licensure or eligibility for government reimbursement or its
compliance with applicable federal or state statutes on regulations may affect
such operator and its affiliates and may affect their ability to pay their rent
or mortgage interest income.

A number of legislative proposals that would affect major reforms of
the health care system have been introduced in Congress, such as additional
Medicare and Medicaid reforms and cost containment measures. We cannot predict
whether any such legislative proposals will be adopted or, if adopted, what
effect, if any, such proposals would have on our business, lessees or
mortgagors.

Competition.

We compete with other real estate investment trusts in that each is
continually seeking attractive investment opportunities in office and senior
housing facilities and other types of real estate. We also compete with banks,
non-bank finance companies, leasing companies and insurance companies.

FEDERAL INCOME TAX CONSIDERATIONS

The following summary of federal income tax considerations is based on
existing law, and is limited to investors who own our shares as an investment
asset rather than as inventory or as property used in a trade or business. The
summary does not discuss the particular tax consequences that might be relevant
to you if you are subject to special rules under the federal income tax law, for
example if you are:

- a bank, life insurance company, regulated investment company,
or other financial institution,

- a broker or dealer in securities or foreign currency,

- a person that has a functional currency other than the U.S.
dollar,

- a person who acquires our shares in connection with his
employment or other performance of services,

- a person subject to alternative minimum tax,

- a person who owns our shares as part of a straddle, hedging
transaction, or conversion transaction, or

- except as specifically described in the following summary, a
tax-exempt entity or a foreign person.


The sections of the Internal Revenue Code that govern the federal income tax
qualification and treatment of a REIT and its shareholders are complex. The
following summary is thus qualified by applicable Internal Revenue Code
provisions, related rules and regulations and administrative and judicial
interpretations, all of which are subject to change, possibly with retroactive
effect. Thus, future legislative, judicial, or administrative actions or
decisions could affect the accuracy of statements made in this summary. No
ruling has been sought from the Internal Revenue Service with respect to any
matter described in this summary, and there can be no assurance that the IRS or
a court will agree with the statements made in this summary. In addition, the
following summary is not exhaustive of all possible tax considerations, and does
not discuss any state, local, or foreign tax considerations. For all these
reasons, we urge you to consult with your tax advisor about the federal income
tax and other tax consequences of the acquisition, ownership and disposition of
our shares.


5
For purposes of this summary, you are a "U.S. shareholder" if you are a
beneficial owner of our shares and for federal income tax purposes are:

(1) a citizen or resident of the United States,

(2) a corporation, partnership or other entity treated as a
corporation or partnership for federal income tax purposes,
that is created or organized in or under the laws of the
United States, any state thereof or the District of Columbia,
unless otherwise provided by Treasury regulations,

(3) an estate the income of which is subject to federal income
taxation regardless of its source, or

(4) a trust if a court within the United States is able to
exercise primary supervision over the administration of the
trust and one or more United States persons have the authority
to control all substantial decisions of the trust, or electing
trusts in existence on August 20, 1996 to the extent provided
in Treasury regulations.

Conversely, you are a "non-U.S. shareholder" if you are a beneficial owner of
our shares and are not a U.S. shareholder.

Taxation as a REIT

We have elected to be taxed as a REIT under Sections 856 through 860 of
the Internal Revenue Code, commencing with our taxable year ending December 31,
1987. Our REIT election, assuming continuing compliance with the federal income
tax qualification tests summarized below, continues in effect for subsequent
taxable years. Although no assurance can be given, we believe that we are
organized, have operated, and will continue to operate in a manner that
qualifies us to be taxed under the Internal Revenue Code as a REIT.

As a REIT, we generally will not be subject to federal income tax on
our net income distributed as dividends to our shareholders. Distributions to
our shareholders generally will be includable in their income as dividends to
the extent the distributions do not exceed our current or accumulated earnings
and profits. A portion of these dividends may be treated as capital gain
dividends, as explained below. No portion of these dividends will be eligible
for the dividends received deduction for corporate shareholders. Distributions
in excess of our current or accumulated earnings and profits generally will be
treated for federal income tax purposes as a return of capital to the extent of
a shareholder's basis in its shares, and will reduce this basis. Our current or
accumulated earnings and profits will generally be allocated first to
distributions on our outstanding preferred shares, if any, and thereafter to
distributions on our common shares. For tax purposes, our distributions per
common share paid in 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996,
1997 and 1998 aggregated $1.085, $.840, $1.13, $1.16, $1.22, $1.25, $1.29,
$1.32, $1.37, $1.41, $1.45 and $1.51 respectively, of which $.289, $.065, $.332,
$.267, $.104, $.218, $.335, $.081, $.161, $.350, $.252 and $.096 respectively,
represented a return of capital. The federal income taxation of our
distributions to you is discussed in more detail in the following sections of
this summary.

Our counsel, Sullivan & Worcester LLP, has opined that we have been
organized and have qualified as a REIT under the Internal Revenue Code for our
1987 through 1998 taxable years, and that our current investments and plan of
operation will enable us to continue to meet the requirements for qualification
and taxation as a REIT under the Internal Revenue Code. These opinions are
conditioned upon the assumption that our leases, our declaration of trust and
by-laws, and all other legal documents to which we are or have been a party have
been and will be complied with by all parties to these documents, upon the
accuracy and completeness of the factual matters described in this Annual
Report, and upon representations made by us. The opinion of Sullivan & Worcester
LLP is based on the law as it exists today, but the law may change in the
future, possibly with retroactive effect. Also, an opinion of counsel is not
binding on the Internal Revenue Service or the courts, and the IRS or a court
could take a position different from that expressed by counsel.

Our qualification and taxation as a REIT will depend upon our ability
to meet the various REIT qualification tests imposed under the Internal Revenue
Code and summarized below. While we believe that we have operated and will
continue to operate in a manner to satisfy the various REIT qualification tests,
Sullivan & Worcester LLP has not reviewed and will not review our compliance
with these tests on a continuing basis. If we fail to qualify as a REIT in any
year, we will be subject to federal income taxation as if we were a domestic
corporation, and our shareholders will be taxed like shareholders of ordinary
corporations. In this event, we could be subject to significant tax liabilities,
and the amount of cash available for distribution to our shareholders may be
reduced or eliminated.


6
If we qualify for taxation as a REIT and distribute to our shareholders
at least 95% of our "real estate investment trust taxable income," computed by
excluding any net capital gain and before taking into account any dividends paid
deduction for which we are eligible, we generally will not be subject to federal
corporate income taxes on the amount distributed. However, even if we qualify
for federal income taxation as a REIT, we may be subject to federal tax in the
following circumstances:

- We will be taxed at regular corporate rates on any
undistributed "real estate investment trust taxable income,"
including our undistributed net capital gains.

- If our alternative minimum taxable income exceeds our taxable
income, we may be subject to the corporate alternative minimum
tax on items of tax preference.

- If we have (1) net income from the sale or other disposition
of "foreclosure property" that is held primarily for sale to
customers in the ordinary course of business or (2) other
nonqualifying income from foreclosure property, we will be
subject to tax on this income at the highest regular corporate
rate, which is currently 35%.

- If we have net income from prohibited transactions, including
sales or other dispositions of inventory or property held
primarily for sale to customers in the ordinary course of
business other than foreclosure property, this income will be
subject to tax at a 100% rate.

- If we fail to satisfy the 75% gross income test or the 95%
gross income test discussed below, but nonetheless maintain
our qualification as a REIT, we will be subject to tax at a
100% rate on the greater of the amount by which we fail the
75% or the 95% test, multiplied by a fraction intended to
reflect our profitability.

- If we fail to distribute for any calendar year at least the
sum of (1) 85% of our REIT ordinary income for that year, (2)
95% of our REIT capital gain net income for that year, and (3)
any undistributed taxable income from prior periods, we will
be subject to a 4% excise tax on the excess of the required
distribution over the amounts actually distributed.

- If we acquire an asset from a corporation in a transaction in
which our basis in the asset is determined by reference to the
basis of the asset in the hands of a present or former C
corporation, and if we subsequently recognize gain on the
disposition of this asset during the ten-year period beginning
on the date on which the asset ceased to be owned by the C
corporation, then we will pay tax at the highest regular
corporate tax rate, which is currently 35%, on the lesser of
(1) the excess of the fair market value of the asset over the
C corporation's basis in the asset on the date the asset
ceased to be owned by the C corporation or (2) the gain we
recognize in the disposition.

If we invest in properties in foreign countries, our profits from these
investments will generally be subject to tax in the countries where those
properties are located. The nature and amount of this taxation will depend on
the laws of the countries where the properties are located. If we operate as we
currently intend, then our taxable income will be distributed to our
shareholders and we will not pay federal corporate income tax, and thus we
generally cannot recover the cost of foreign taxes imposed on our foreign
investments by claiming foreign tax credits against our federal income tax
liability. We will also not be able to pass through to our shareholders any
foreign tax credits.

If we fail to qualify for federal income taxation as a REIT in any
taxable year, then we will be subject to federal taxes in the same manner as an
ordinary corporation. Distributions to our shareholders in any year in which we
fail to qualify as a REIT will not be deductible by us, nor will these
distributions be required to be made. In that event, to the extent of our
current and accumulated earnings and profits, all distributions to our
shareholders will be taxable as ordinary dividend income, and subject to
limitations in the Internal Revenue Code will be eligible for the dividends
received deduction for corporations. We would also generally be disqualified
from federal income taxation as a REIT for the four taxable years following
disqualification. Failure to qualify for federal income taxation as a REIT for
even one year could result in our incurring substantial indebtedness or
liquidating substantial investments in order to pay the resulting
corporate-level taxes.

REIT Qualification Requirements

General Requirements. Section 856(a) of the Internal Revenue Code
defines a REIT as a corporation, trust or association:

(1) that is managed by one or more trustees or directors;

(2) the beneficial ownership of which is evidenced by transferable
shares or by transferable certificates of beneficial interest;

(3) that would be taxable, but for Sections 856 through 859 of the
Internal Revenue Code, as an ordinary domestic corporation;

(4) that is neither a financial institution nor an insurance
company subject to special provisions of the Internal Revenue
Code;

(5) the beneficial ownership of which is held by 100 or more
persons;

(6) that is not "closely held" as defined under the personal
holding company stock ownership test, as described below; and

(7) that meets other tests regarding income, assets and
distributions, all as described below.

Section 856(b) of the Internal Revenue Code provides that conditions (1) to (4),
inclusive, must be met during the entire taxable year and that condition (5)
must be met during at least 335 days of a taxable year of 12 months, or during a
proportionate part of a taxable year of less than 12 months. Section 856(h)(2)
of the Internal Revenue Code provides that conditions (5) and (6) need not be
met for our first taxable year as a REIT. We believe that we have satisfied
conditions (1) to (6), inclusive, during the requisite periods for each of our
taxable years ending on or before December 31, 1998, and that we will continue
to satisfy those conditions.
There can, however, be no assurance in this regard.

By reason of condition (6) above, we will fail to qualify as a REIT for
a taxable year if at any time during the last half of the year more than 50% in
value of our outstanding shares is owned directly or indirectly by five or fewer
individuals. To help comply with condition (6), our declaration of trust
contains provisions restricting transfers of our shares and giving the trustees
the power to redeem our shares. In addition, commencing with our 1998 taxable
year, if we comply with applicable Treasury regulations for ascertaining the
ownership of our outstanding shares and do not know, or exercising reasonable
diligence would not have known, whether we failed condition (6), then we will be
treated as satisfying condition (6). Also, our failure to comply with these
applicable Treasury regulations for ascertaining ownership of our outstanding
shares may result in a penalty to us of $25,000, or $50,000 for intentional
violations. Accordingly, we intend to comply with these applicable Treasury
regulations, and request annually from record holders of significant percentages
of our shares information regarding the ownership of our shares. Under our
declaration of trust, our shareholders are required to respond to these requests
for information.

The rule that an entity will fail to qualify as a REIT for a taxable
year if at any time during the last half of the year more than 50% in value of
its outstanding shares is owned directly or indirectly by five or fewer
individuals is relaxed in the case of pension trusts owning shares in a REIT.
Shares in a REIT held by a pension trust are treated as held directly by the
pension trust's beneficiaries in proportion to their actuarial interests in the
pension trust. Consequently, five or fewer pension trusts could own more than
50% of the interests in an entity without jeopardizing that entity's federal
income tax qualification as a REIT. However, as discussed below, if the REIT is
a "pension-held REIT," each pension trust owning more than 10% of the REIT's
shares by value generally will be taxed on a portion of the dividends received
from the REIT, based on the ratio of (1) the REIT's gross income for the year
that would be unrelated trade or business income if the REIT were a qualified
pension trust to (2) the REIT's total gross income for the year.

Our Wholly-Owned Subsidiaries. Section 856(i) of the Internal Revenue
Code provides that any corporation 100% of whose stock is held by the REIT is a
qualified REIT subsidiary and shall not be treated as a separate corporation.
The assets, liabilities and items of income, deduction, and credit of a
qualified REIT subsidiary are treated as the REIT's. We believe that each of our
direct and indirect wholly-owned subsidiaries is either a qualified REIT
subsidiary within the meaning of Section 856(i) of the Internal Revenue Code, or
a noncorporate entity that for federal income tax purposes is not treated as
separate from its owner pursuant to


8
regulations  under Section 7701 of the Internal  Revenue Code. Thus, in applying
all the federal income tax REIT qualification requirements described in this
summary, our direct and indirect wholly-owned subsidiaries are ignored, and all
assets, liabilities and items of income, deduction and credit of our direct and
indirect wholly-owned subsidiaries are treated as ours.

Our Investments through Partnerships. We have invested, and in the
future may invest, in real estate through one or more limited partnerships or
limited liability companies that are treated as partnerships for federal income
tax purposes. In the case of a REIT that is a partner in a partnership,
regulations under the Internal Revenue Code provide that, for purposes of the
REIT qualification requirements regarding income and assets discussed below, the
REIT is deemed to own its proportionate share of the assets of the partnership
corresponding to the REIT's proportionate capital interest in the partnership
and is deemed to be entitled to the income of the partnership attributable to
this proportionate share. In addition, for these purposes, the character of the
assets and gross income of the partnership generally retain the same character
in the hands of the REIT. Accordingly, our proportionate share of the assets,
liabilities, and items of income of each partnership in which we are a partner
are treated as ours for purposes of the income tests and asset tests discussed
below. In contrast, for purposes of the distribution requirement discussed
below, we must take into account as a partner our distributive share of the
partnership's income as determined under the general federal income tax rules
governing partners and partnerships under Sections 701 through 777 of the
Internal Revenue Code.

Income Tests. There have been three gross income requirements for
qualification as a REIT under the Internal Revenue Code, but only the first two
still apply in our current taxable years:

- First, at least 75% of our gross income, excluding gross
income from sales or other dispositions of property held
primarily for sale, must be derived from investments relating
to real property, including "rents from real property" as
defined under Section 856 of the Internal Revenue Code,
mortgages on real property, or shares in other REITs. When we
receive new capital in exchange for our shares or in a public
offering of five-year or longer debt instruments, income
attributable to the temporary investment of this new capital
in stock or a debt instrument, if received or accrued within
one year of our receipt of the new capital, is generally also
qualifying income under the 75% test.

- Second, at least 95% of our gross income, excluding gross
income from sales or other dispositions of property held
primarily for sale, must be derived from a combination of (1)
items of real property income that satisfy the 75% test
described above, (2) dividends, (3) interest, (4) payments
under interest rate swap or cap agreements, options, futures
contracts, forward rate agreements, or similar financial
instruments, and (5) gain from the sale or disposition of
stock, securities, or real property.

- Third, for our 1997 and prior taxable years, less than 30% of
our gross income must have been derived from (1) short-term
gain from the sale or other disposition of stock or
securities, including stock in other REITs or dispositions of
interest rate swap or cap agreements, and (2) gain from
prohibited transactions or other dispositions of real property
held for less than four years, other than involuntary
conversions and sales of foreclosure property.

For purposes of these three requirements, income derived from a "shared
appreciation provision" in a mortgage loan is generally treated as gain
recognized on the sale of the property to which it relates. Although we will use
our best efforts to ensure that the income generated by our investments will be
of a type which satisfies both the 75% and 95% gross income tests, there can be
no assurance in this regard.

In order to qualify as "rents from real property" under Section 856 of
the Internal Revenue Code, several requirements must be met:

- First, the amount of rent received generally must not be
determined from the income or profits of any person, but may
be based on receipts or sales.

- Second, rents do not qualify if the REIT owns 10% or more of
the tenant, whether directly or after application of
attribution rules. While we intend not to lease property to
any party if rents from that property would not qualify as
rents from real property, application of the 10% ownership
rule is dependent upon complex attribution rules and
circumstances that may be beyond our control. For example,
ownership directly or by attribution by an unaffiliated third
party of more than 10% of our shares and more than 10% of the
stock of one of our lessees would result in this lessee's

9
rents  not  qualifying  as  rents  from  real  property.   Our
declaration of trust provides that transfers or purported
acquisitions, directly or by attribution, of shares that could
result in our disqualification as a REIT under the Internal
Revenue Code are null and void and permits the trustees to
repurchase shares to the extent necessary to maintain our
status as a REIT under the Internal Revenue Code.
Nevertheless, there can be no assurance that these provisions
in our declaration of trust will be effective to prevent our
REIT status under the Internal Revenue Code from being
jeopardized under the 10% lessee affiliate rule. Furthermore,
there can be no assurance that we will be able to monitor and
enforce these restrictions, nor will our shareholders
necessarily be aware of ownership of shares attributed to them
under the Internal Revenue Code's attribution rules.

- Third, in order for rents to qualify, we generally must not
manage the property or furnish or render services to the
tenants of the property, except through an independent
contractor from whom we derive no income. There is an
exception to this rule permitting a REIT to perform customary
tenant services of the sort which a tax-exempt organization
could perform without being considered in receipt of
"unrelated business taxable income" as defined in Section
512(b)(3) of the Internal Revenue Code. In addition, for our
1998 and later taxable years, a de minimis amount of
noncustomary services will not disqualify income as "rents
from real property" so long as the value of the impermissible
services does not exceed 1% of the gross income of the
property.

- Fourth, if rent attributable to personal property leased in
connection with a lease of real property is 15% or less of the
total rent received under the lease, then the rent
attributable to personal property will qualify as rents from
real property; but if this 15% threshold is exceeded, the rent
attributable to personal property will not so qualify. The
portion of rental income treated as attributable to personal
property is determined according to the ratio of the tax basis
of the personal property to the total tax basis of the real
and personal property which is rented.

Substantially all of our gross income has been and is expected to continue to be
attributable to rental income. We believe that all or substantially all our
rents have qualified and will continue to qualify as rents from real property
for purposes of Section 856 of the Internal Revenue Code, but if for some reason
a significant amount of our rents do not so qualify, we may fail the 95% or 75%
gross income tests.

In order to qualify as mortgage interest on real property for purposes
of the 75% test, interest must derive from a mortgage loan secured by real
property with a fair market value at least equal to the amount of the loan. If
the amount of the loan exceeds the fair market value of the real property, the
interest will be treated as interest on a mortgage loan in a ratio equal to the
ratio of the fair market value of the real property to the total amount of the
mortgage loan.

Any gain we realize on the sale of property held as inventory or other
property held primarily for sale to customers in the ordinary course of business
will be treated as income from a prohibited transaction that is subject to a
penalty tax at a 100% rate. This prohibited transaction income also may have an
adverse effect upon our ability to satisfy the 75% and 95% gross income tests
for federal income tax qualification as a REIT. We cannot provide assurances as
to whether or not the IRS might successfully assert that one or more of our
dispositions is subject to the 100% penalty tax. However, we believe that any
occasional disposition of real estate that we might make will not be subject to
the 100% penalty tax, because we intend to: (1) own our real estate assets for
investment with a view to long-term income production and capital appreciation,
(2) engage in the business of developing, owning and operating our existing real
estate assets and acquiring, developing, owning and operating other real estate
assets, and (3) make occasional dispositions of real estate assets consistent
with our long-term investment objectives.

If we fail to satisfy one or both of the 75% or 95% gross income tests
for any taxable year, we may nevertheless qualify as a REIT for that year if:
(1) our failure to meet the test was due to reasonable cause and not due to
willful neglect, (2) we report the nature and amount of each item of our income
included in the 75% or 95% gross income tests for that taxable year on a
schedule attached to our tax return, and (3) any incorrect information on the
schedule was not due to fraud with intent to evade tax. It is impossible to
state whether in all circumstances we would be entitled to the benefit of this
relief provision for the 75% and 95% gross income tests. Even if this relief
provision did apply to us, a special tax equal to 100% is imposed upon the
greater of the amount by which we failed the 75% test or the 95% test,
multiplied by a fraction intended to reflect our profitability. No similar
relief provision is available if we failed the 30% gross income test for any
taxable year in which that test was applicable.

Asset Tests. At the close of each quarter of each taxable year, we must
also satisfy three percentage tests relating to the nature of our assets:

10
-        First,  at least  75% of the value of our  total  assets  must
consist of (1) real estate assets, (2) cash and cash items,
(3) shares in other REITs, (4) government securities, and (5)
stock or debt instruments purchased with proceeds of a stock
offering or an offering of our debt with a term of at least
five years, but only for the one-year period commencing with
our receipt of the offering proceeds.

- Second, not more than 25% of our total assets may be
represented by securities other than those securities that
count favorably toward the preceding 75% asset test.

- Third, of the investments included in the preceding 25% asset
class, the value of any one issuer's securities that we own
may not exceed 5% of the value of our total assets, and we may
not own more than 10% of any one issuer's outstanding voting
securities.

When a failure to satisfy the above asset tests results from an acquisition of
securities or other property during a quarter, the failure can be cured by
disposition of sufficient nonqualifying assets within 30 days after the close of
that quarter. We have maintained and intend to continue to maintain records of
the value of our assets to document our compliance with the above three asset
tests, and to take actions as may be required to cure any failure to satisfy the
tests within 30 days after the close of any quarter.

Annual Distribution Requirements. In order to qualify for taxation as a
REIT under the Internal Revenue Code, we are required to make annual
distributions other than capital gain dividends to our shareholders in an amount
at least equal to the excess of:

(A) the sum of (1) 95% of our "real estate investment trust
taxable income," as defined in Section 857 of the Internal
Revenue Code, but computed without regard to the dividends
paid deduction and net capital gain, and (2) 95% of our net
income after tax, if any, from property received in
foreclosure, over

(B) the sum of our qualifying noncash income, e.g., imputed rental
income or income from transactions inadvertently failing to
qualify as like-kind exchanges.

These distributions must be paid in the taxable year to which they relate, or in
the following taxable year if declared before we timely file our tax return for
the earlier taxable year and if paid on or before the first regular distribution
payment after that declaration. Dividends declared in October, November, or
December and paid during the following January will be treated as having been
both paid and received on December 31 of the prior taxable year. A distribution
which is not pro rata within a class of our beneficial interests entitled to a
distribution, or which is not consistent with the rights to distributions
between our classes of beneficial interests, is a preferential distribution that
is not taken into consideration for purposes of the distribution requirement,
and accordingly the payment of a preferential distribution could affect our
ability to meet the distribution requirement. Taking into account our
distribution policies, including our dividend reinvestment plan, we believe that
we have not made and expect that we will not make any preferential
distributions. The distribution requirements may be waived by the IRS if a REIT
establishes that it failed to meet them by reason of distributions previously
made to meet the requirements of the 4% excise tax discussed below. To the
extent that we do not distribute all of our net capital gain and all of our real
estate investment trust taxable income, as adjusted, we will be subject to tax
on undistributed amounts.

In addition, we will be subject to a 4% excise tax to the extent we
fail within a calendar year to make required distributions to our shareholders
of 85% of our ordinary income and 95% of our capital gain net income plus the
excess, if any, of the "grossed up required distribution" for the preceding
calendar year over the amount treated as distributed for that preceding calendar
year. For this purpose, the term "grossed up required distribution" for any
calendar year is the sum of our taxable income for the calendar year without
regard to the deduction for dividends paid and all amounts from earlier years
that are not treated as having been distributed under the provision.

If we do not have enough cash or other liquid assets to meet the 95%
distribution requirements, we may find it necessary to arrange for new debt or
equity financing to provide funds for required distributions, or else our REIT
status for federal income tax purposes could be jeopardized. We can provide no
assurance that financing would be available for these purposes on favorable
terms.

If we fail to distribute sufficient dividends for any year, we may be
able to rectify this failure by paying "deficiency dividends" to shareholders in
a later year. These deficiency dividends may be included in our deduction for
dividends paid for the earlier year, but an interest charge would be imposed
upon us for the delay in distribution.

11
Although  we may be  able  to  avoid  being  taxed  on  amounts  distributed  as
deficiency dividends, we will remain liable for the 4% excise tax discussed
above.

Depreciation and Federal Income Tax Treatment of Leases

For federal income tax purposes, including for purposes of computing
our earnings and profits, we have generally elected to depreciate our real
property on a straight-line basis over 40 years and our personal property over
12 years. We will be entitled to depreciation deductions from our facilities
only if we are treated for federal income tax purposes as the owner of the
facilities. This means that the leases of the facilities must be classified for
federal income tax purposes as true leases, rather than as sales or financing
arrangements. As to approximately 0.7% of our leased facilities which constitute
personal property, it is not entirely clear that we will be treated as the owner
of this personal property.

In the case of sale-leaseback arrangements, the IRS could assert that
we realized prepaid rental income in the year of purchase to the extent that the
value of a leased property exceeds our purchase price for that property. Because
of the lack of clear precedent, we cannot provide assurances as to whether or
not the IRS might successfully assert the existence of prepaid rental income in
our sale-leaseback transactions.

Additionally, Section 467 of the Internal Revenue Code, which concerns
leases with increasing rents, may apply to those of our leases which provide for
rents that increase from one period to the next. Section 467 of the Internal
Revenue Code provides that in the case of a so-called "disqualified leaseback
agreement," rental income must be accrued at a constant rate. Where constant
rent accrual is required, we could recognize rental income from a lease in
excess of cash rents and, as a result, encounter difficulty in meeting the 95%
distribution requirement. "Disqualified leaseback agreements" include leaseback
transactions where a principal purpose for providing increasing rent under the
agreement is the avoidance of federal income tax. Because Section 467 of the
Internal Revenue Code directs the Treasury to issue regulations providing that
rents will not be treated as increasing for tax avoidance purposes where the
increases are based upon a fixed percentage of lessee receipts, and because
regulations proposed to be effective for "disqualified leaseback agreements"
entered into after June 3, 1996 adopt this rule, the additional rent provisions
in our leases that are based on a fixed percentage of lessee receipts generally
should not cause the leases to be "disqualified leaseback agreements." In
addition, the legislative history of Section 467 of the Internal Revenue Code
indicates that the Treasury should issue regulations under which leases
providing for fluctuations in rents by no more than a reasonable percentage from
the average rent payable over the term of the lease will be deemed not motivated
by tax avoidance, and the proposed regulations permit a 10% fluctuation.

Taxation of U.S. Shareholders

As long as we qualify as a REIT for federal income tax purposes, a
distribution by us to our U.S. shareholders that we do not designate as a
capital gain dividend will be treated as an ordinary income dividend to the
extent that it is made out of our current or accumulated earnings and profits.
Distributions made out of our current or accumulated earnings and profits that
we properly designate as capital gain dividends will be taxed as long-term
capital gains, as discussed below, to the extent they do not exceed our actual
net capital gain for the taxable year. However, corporate U.S. shareholders may
be required to treat up to 20% of any capital gain dividend as ordinary income
under Section 291 of the Tax Code. In addition, we may elect to retain net
capital gain income and treat it as constructively distributed. In that case,

(1) we will be taxed at regular corporate capital gains tax rates
on retained amounts,

(2) each U.S. shareholder will be taxed on its designated
proportionate share of our retained net capital gains as
though that amount were distributed and designated a capital
gain dividend,

(3) each U.S. shareholder will receive a credit for its designated
proportionate share of the tax that we pay,

(4) each U.S. shareholder will increase its adjusted basis in our
shares by the excess of the amount of its proportionate share
of these retained net capital gains over its proportionate
share of this tax that we pay, and

(5) both we and our corporate U.S. shareholders will make
commensurate adjustments in our respective earnings and
profits for federal income tax purposes.

If we elect to retain our net capital gain in this fashion, we will notify U.S.
shareholders of the relevant tax information within 60 days after the close of
the affected taxable year. Because we are a REIT, neither our ordinary


12
income  dividends nor our capital gain  dividends will qualify for any dividends
received deduction for our corporate U.S. shareholders.

For noncorporate U.S. shareholders, long-term capital gains are
generally taxed at maximum rates of 20% or 25%, depending upon the type of
property disposed of and the previously claimed depreciation with respect to
this property at the time of disposition. If for any taxable year we designate
as capital gain dividends any portion of the dividends paid or made available
for the year to our shareholders, including our retained capital gains treated
as capital gain dividends, then the portion of the capital gain dividends so
designated that will be allocated to the holders of a particular class of our
shares will on a percentage basis equal the ratio of (1) the amount of the total
dividends paid or made available for the year to the holders of that class of
shares, to (2) the total dividends paid or made available for the year to
holders of all classes of our shares. We will similarly designate the portion of
any capital gain dividend that is to be taxed to noncorporate U.S. shareholders
at the maximum rates of 20% or 25% so that the designations will be proportional
among all classes of our shares.

Distributions in excess of current or accumulated earnings and profits
will not be taxable to a U.S. shareholder to the extent that they do not exceed
the U.S. shareholder's adjusted basis in our shares, but will reduce the U.S.
shareholder's basis in our shares. To the extent that these excess distributions
exceed the adjusted basis of a U.S. shareholder's shares, they will be included
in income as capital gain, with long-term gain generally taxed to noncorporate
U.S. shareholders at a maximum rate of 20%. No U.S. shareholder may include on
his federal income tax return any of our net operating losses or any of our
capital losses.

Dividends that we declare in October, November or December of a taxable
year to shareholders of record on a date in those months will be deemed to have
been received by shareholders on December 31 of that taxable year, provided we
actually pay these dividends during the following January. Also, items that are
treated differently for regular and alternative minimum tax purposes are to be
allocated between a REIT and its shareholders under Treasury regulations which
are to be prescribed. It is possible that these Treasury regulations would
require tax preference items to be allocated to our shareholders with respect to
any accelerated depreciation or other tax preference items that we claim.

The sale or exchange of our shares will result in recognition of gain
or loss to a U.S. shareholder in an amount equal to the difference between the
amount realized and the U.S. shareholder's adjusted basis in the shares sold or
exchanged. This gain or loss will be capital gain or loss, and will be long-term
capital gain or loss if the U.S. shareholder's holding period in the shares
exceeds one year. Long-term capital gains will generally be taxed to
noncorporate U.S. shareholders at a maximum rate of 20%. In addition, any loss
upon a sale or exchange of our shares by a U.S. shareholder who has held our
shares for six months or less will generally be treated as a long-term capital
loss to the extent of our distributions required to be treated by the U.S.
shareholder as long-term capital gain. The relevant six-month holding period is
determined after applying the holding period rules under Section 857 of the
Internal Revenue Code.

U.S. shareholders other than corporations who borrow funds to finance
their acquisition of our shares could be limited in the amount of deductions
allowed for the interest paid on the indebtedness incurred. Under Section 163(d)
of the Internal Revenue Code, interest paid or accrued on indebtedness incurred
or continued to purchase or carry property held for investment is generally
deductible only to the extent of the investor's net investment income. A U.S.
shareholder's net investment income will include ordinary income dividend
distributions and, if an appropriate election is made by the U.S. shareholder,
capital gain dividend distributions received from us; however, distributions
treated as a nontaxable return of the U.S. shareholder's basis will not enter
into the computation of net investment income. Under Section 469 of the Internal
Revenue Code, U.S. shareholders, except for corporations that are other than
closely held C corporations or personal service corporations, generally will not
be entitled to deduct losses from so-called passive activities except to the
extent of their income from passive activities. For purposes of these rules,
distributions received by a U.S. shareholder from us will not be treated as
income from a passive activity and thus will not be available to offset a U.S.
shareholder's passive activity losses.

Taxation of Tax-Exempt U.S. Shareholders

In Revenue Ruling 66-106, the IRS ruled that amounts distributed by a
REIT to a tax-exempt employees' pension trust did not constitute "unrelated
business taxable income," even though the REIT may have financed some its
activities with acquisition indebtedness. Although revenue rulings are
interpretive in nature and subject to revocation or modification by the IRS,
based upon the analysis and conclusion of Revenue Ruling 66-106, our
distributions made to U.S. shareholders that are tax-exempt pension plans,
individual retirement accounts, or other qualifying tax-exempt entities should
not constitute unrelated business taxable income, unless the U.S. shareholder



13
has  financed  its  acquisition  of our shares with  "acquisition  indebtedness"
within the meaning of the Internal Revenue Code, or our shares are otherwise
used in an unrelated trade or business conducted by the U.S.
shareholder.

Special rules apply to tax-exempt pension trusts, including so-called
401(k) plans but excluding individual retirement accounts or government pension
plans, that own more than 10% by value of a "pension-held REIT" at any time
during a taxable year. The pension trust may be required to treat a percentage
of all dividends received from the pension-held REIT during the year as
unrelated business taxable income. This percentage is equal to the ratio of

(1) the pension-held REIT's gross income derived from the conduct
of unrelated trades or businesses, determined as if the
pension-held REIT were a tax-exempt pension fund, less direct
expenses related to that income, to

(2) the pension-held REIT's gross income from all sources, less
direct expenses related to that income,

except that this percentage shall be deemed to be zero unless it would otherwise
equal or exceed 5%. A REIT is a pension-held REIT if (a) the REIT is
"predominantly held" by tax-exempt pension trusts, and (b) the REIT would
otherwise fail to satisfy the "closely held" ownership requirement discussed
above if the stock or beneficial interests in the REIT held by tax-exempt
pension trusts were viewed as held by tax-exempt pension trusts rather than by
their respective beneficiaries. A REIT is predominantly held by tax-exempt
pension trusts if at least one tax-exempt pension trust owns more than 25% by
value of the REIT's stock or beneficial interests, or if one or more tax-exempt
pension trusts, each owning more than 10% by value of the REIT's stock or
beneficial interests, own in the aggregate more than 50% by value of the REIT's
stock or beneficial interests. Because of the restrictions in our declaration of
trust regarding the ownership concentration of our shares, we believe that we
are not and will not be a pension-held REIT. However, because our shares are
publicly traded, we cannot completely control whether or not we are or will
become a pension-held REIT.

Taxation of Non-U.S. Shareholders

The rules governing the federal income taxation of non-U.S.
shareholders are complex, and the following discussion is intended only as a
summary of these rules. If you are a non-U.S. shareholder, you should consult
with your own tax advisor to determine the impact of federal, state, local, and
foreign tax laws, including any tax return filing and other reporting
requirements, with respect to your investment in our shares.

In general, a non-U.S. shareholder will be subject to regular federal
income tax in the same manner as our U.S. shareholders with respect to its
investment in our shares if that investment is effectively connected with the
non-U.S. shareholder's conduct of a trade or business in the United States. In
addition, a corporate non-U.S. shareholder that receives income that is or is
deemed effectively connected with a trade or business in the United States may
also be subject to the 30% branch profits tax under Section 884 of the Tax Code,
which is payable in addition to regular federal corporate income tax. The
balance of this discussion on the federal income taxation of non-U.S.
shareholders addresses only those non-U.S. shareholders whose investment in our
shares is not effectively connected with the conduct of a trade or business in
the United States.

A distribution by us to a non-U.S. shareholder that is not attributable
to gain from the sale or exchange by us of a United States real property
interest and that is not designated by us as a capital gain dividend will be
treated as an ordinary income dividend to the extent that it is made out of
current or accumulated earnings and profits. A distribution of this type will
generally be subject to federal income tax and withholding at the rate of 30%,
or the lower rate that may be specified by a tax treaty if the non-U.S.
shareholder has in the manner prescribed by the IRS demonstrated its entitlement
to benefits under a tax treaty. Because we cannot determine our current and
accumulated earnings and profits until the end of our taxable year, withholding
at the rate of 30% or applicable lower treaty rate will be imposed on the gross
amount of any distribution to a non-U.S. shareholder that we make and do not
designate a capital gain dividend. Notwithstanding this withholding on
distributions in excess of our current and accumulated earnings and profits,
these distributions are a nontaxable return of capital to the extent that they
do not exceed the non-U.S. shareholder's adjusted basis in our shares, and the
nontaxable return of capital will reduce the adjusted basis in these shares. To
the extent that distributions in excess of current and accumulated earnings and
profits exceed the non-U.S. shareholder's adjusted basis in our shares, the
distributions will give rise to tax liability if the non-U.S. shareholder would
otherwise be subject to tax on any gain from the sale or exchange of our shares,
as discussed below. A non-U.S. shareholder may seek a refund of amounts withheld
on distributions to him in excess of our current and accumulated earnings and
profits, provided that the required information is furnished to the IRS.


14
For any year in which we qualify as a REIT, our distributions  that are
attributable to gain from the sale or exchange of a United States real property
interest are taxed to a non-U.S. shareholder as if these distributions were
gains effectively connected with a trade or business in the United States
conducted by the non-U.S. shareholder. Accordingly, a non-U.S. shareholder will
be taxed on these amounts at the normal capital gain rates applicable to a U.S.
shareholder, subject to any applicable alternative minimum tax and a special
alternative minimum tax in the case of nonresident alien individuals; the
non-U.S. shareholder would be required to file a United States federal income
tax return reporting these amounts, even if applicable withholding were imposed
as described below; and corporate non-U.S. shareholders may owe the 30% branch
profits tax under Section 884 of the Tax Code in respect of these amounts. We
will be required to withhold from distributions to non-U.S. shareholders, and
remit to the IRS, 35% of the maximum amount of any distribution that could be
designated by us as a capital gain dividend. In addition, for purposes of this
withholding rule, if we designate prior distributions as capital gain dividends,
then subsequent distributions up to the amount of the designated prior
distributions will be treated as capital gain dividends. The amount of any tax
withheld is creditable against the non-U.S. shareholder's federal income tax
liability, and any amount of tax withheld in excess of that tax liability may be
refunded provided that an appropriate claim for refund is filed with the IRS. If
for any taxable year we designate as capital gain dividends any portion of the
dividends paid or made available for the year to our shareholders, including our
retained capital gains treated as capital gain dividends, then the portion of
the capital gain dividends so designated that will be allocated to the holders
of a particular class of our shares will on a percentage basis equal the ratio
of (1) the amount of the total dividends paid or made available for the year to
the holders of that class of shares, to (2) the total dividends paid or made
available for the year to holders of all classes of our shares.

Tax treaties may reduce the withholding obligations on our
distributions. Under some treaties, however, rates below 30% generally
applicable to ordinary income dividends from United States corporations may not
apply to ordinary income dividends from a REIT. If the amount of tax withheld by
us with respect to a distribution to a non-U.S. shareholder exceeds the
shareholder's federal income tax liability with respect to the distribution, the
non-U.S. shareholder may file for a refund of the excess from the IRS. In this
regard, note that the 35% withholding tax rate on capital gain dividends
corresponds to the maximum income tax rate applicable to corporate non-U.S.
shareholders but is higher than the 20% and 25% maximum rates on capital gains
generally applicable to noncorporate non-U.S. shareholders. Generally effective
with respect to distributions paid after December 31, 1999, new Treasury
regulations alter the information reporting and backup withholding rules
applicable to non-U.S. shareholders and provide presumptions under which a
non-U.S. shareholder is subject to backup withholding and information reporting
until we receive certification from the shareholder of its non-U.S. shareholder
status. The new Treasury regulations also provide special rules to determine
whether, for purposes of determining the applicability of a tax treaty, our
distributions to a non-U.S. shareholder that is an entity should be treated as
paid to the entity or to those owning an interest in that entity, and whether
the entity or its owners are entitled to benefits under the tax treaty.

If our shares are not "United States real property interests" within
the meaning of Section 897 of the Tax Code, a non-U.S. shareholder's gain on
sale of our shares generally will not be subject to federal income taxation,
except that a nonresident alien individual who was present in the United States
for 183 days or more during the taxable year will be subject to a 30% tax on
this gain. Our shares will not constitute a United States real property interest
if we are a "domestically controlled REIT." A domestically controlled REIT is a
REIT in which at all times during the preceding five-year period less than 50%
in value of its shares is held directly or indirectly by foreign persons. We
believe that we are and will be a domestically controlled REIT and thus that a
non-U.S. shareholder's gain on sale of our shares will not be subject to federal
income taxation. However, because our shares are publicly traded, we can provide
no assurance that we will be a domestically controlled REIT. If we are not a
domestically controlled REIT, a non-U.S. shareholder's gain on sale of our
shares will not be subject to federal income taxation as a sale of a United
States real property interest, if (1) our shares are "regularly traded," as
defined by applicable Treasury regulations, on an established securities market
such as the New York Stock Exchange, and (2) the non-U.S. shareholder has at all
times during the preceding five years owned 5% or less by value of that class of
our shares. If the gain on the sale of our shares were subject to federal income
taxation, the non-U.S. shareholder would generally be subject to the same
treatment as a U.S. shareholder with respect to its gain, would be required to
file a United States federal income tax return reporting that gain, and in the
case of corporate non-U.S. shareholders might owe branch profits tax under
Section 884 of the Tax Code. In any event, a purchaser of our shares from a
non-U.S. shareholder will not be required to withhold on the purchase price if
the purchased shares are regularly traded on an established securities market or
if we are a domestically controlled REIT. Otherwise, the purchaser of our shares
may be required to withhold 10% of the purchase price paid to the non-U.S.
shareholder and to remit the withheld amount to the IRS.



15
Backup Withholding and Information Reporting Requirements

We will report to our U.S. shareholders and to the IRS the amount of
dividends paid during each calendar year and the amount of tax withheld, if any.
Under the backup withholding rules, a U.S. shareholder may be subject to backup
withholding at the rate of 31% with respect to dividends paid unless the U.S.
shareholder (1) is a corporation or comes within other exempt categories and
when required demonstrates that fact or (2) provides a taxpayer identification
number, certifies as to no loss of exemption from backup withholding rules and
otherwise complies with applicable requirements of the backup withholding rules.
A U.S. shareholder who does not provide us with his correct taxpayer
identification number may be subject to penalties imposed by the IRS. In
addition, we may be required to withhold a portion of capital gain distributions
to any U.S. shareholder who fails to certify his non-foreign status to us.

We will report to our non-U.S. shareholders and to the IRS the amount
of dividends paid during each calendar year and the amount of tax withheld, if
any. These information reporting requirements apply regardless of whether
withholding was reduced or eliminated by an applicable tax treaty. As discussed
above, withholding rates of 30% and 35% may apply to distributions to non-U.S.
shareholders, and new Treasury regulations will when effective alter the
information reporting and withholding rules applicable to non-U.S. shareholders.

The payment of the proceeds from the disposition of our shares to or
through the United States office of a broker will generally be subject to
information reporting and backup withholding at a rate of 31% unless under
penalties of perjury you certify your status as a non-U.S. shareholder or
otherwise establish an exemption. The payment of the proceeds from the
disposition of our shares to or through a non-United States office of a broker
generally will not be subject to backup withholding and information reporting.

Any amounts required to be withheld from payments to you will be
collected by us or other applicable withholding agents for remittance to the
IRS. Amounts withheld are generally not an additional tax and may be refunded or
credited against your federal income tax liability, provided that you furnish
the required information to the IRS. In addition, the absence or existence of
applicable withholding does not necessarily excuse you from filing applicable
United States federal income tax returns.

Other Tax Considerations

You should recognize that our and our shareholders' present federal
income tax treatment may be modified by legislative, judicial, or administrative
actions at any time, which actions may be retroactive in effect. The rules
dealing with federal income taxation are constantly under review by the
Congress, the IRS and the Treasury Department, and statutory changes as well as
promulgation of new regulations, revisions to existing regulations, and revised
interpretations of established concepts occur frequently. No prediction can be
made as to the likelihood of passage of any new tax legislation or other
provisions either directly or indirectly affecting us or our shareholders.
Revisions in federal income tax laws and interpretations of these laws could
adversely affect the tax consequences of an investment in our shares. We and our
shareholders may also be subject to state or local taxation in various state or
local jurisdictions, including those in which we or our shareholders transact
business or reside. State and local tax treatment may not conform to the federal
income tax consequences discussed above.

We thus urge you to consult your own tax advisor regarding the specific
federal, state, local, foreign and other tax consequences to you of the
acquisition, ownership, and disposition of our shares.

ERISA PLANS, KEOGH PLANS AND INDIVIDUAL RETIREMENT ACCOUNTS

General Fiduciary Obligations

Fiduciaries of a pension, profit-sharing or other employee benefit plan
subject to Title I of the Employee Retirement Income Security Act of 1974
("ERISA") must consider the following:

- whether their investment in our shares satisfies the
diversification requirements of ERISA;

- whether the investment is prudent in light of possible
limitations on the marketability of our shares;

- whether they have authority to acquire our shares under the
applicable governing instrument and Title I of ERISA; and


16
-        whether the  investment  is  otherwise  consistent  with their
fiduciary responsibilities.

Trustees and other fiduciaries of an ERISA plan may incur personal
liability for any loss suffered by the plan on account of a violation of their
fiduciary responsibilities. In addition, these fiduciaries may be subject to a
civil penalty of up to 20% of any amount recovered by the plan on account of a
violation. Fiduciaries of any Individual Retirement Account, "Keogh Plan" or
other qualified retirement plan not subject to Title I of ERISA should consider
that an IRA or such a plan may only make investments that are authorized by the
appropriate governing instrument. Fiduciary shareholders should consult their
own legal advisors if they have any concern as to whether the investment is
consistent with the foregoing criteria.

Prohibited Transactions

Fiduciaries of ERISA plans and persons making the investment decision
for an IRA or other non-ERISA plan should also consider the application of the
prohibited transaction provisions of ERISA and the Internal Revenue Code in
making their investment decision. Sales and other transactions between an ERISA
plan, an IRA, or certain types of non-ERISA plans such as Keogh plans
("Non-ERISA Plans") and persons related to it are prohibited transactions. The
particular facts concerning the sponsorship, operations and other investments of
an ERISA plan, IRA, or other Non-ERISA Plan may cause a wide range of other
persons to be treated as disqualified persons or parties in interest with
respect to it. A prohibited transaction, in addition to imposing potential
personal liability upon fiduciaries of ERISA Plans, may also result in the
imposition of an excise tax under the Internal Revenue Code or a penalty under
ERISA upon the disqualified person or party in interest with respect to the plan
or IRA. If the disqualified person who engages in the transaction is the
individual on behalf of whom an IRA is maintained or his beneficiary, the IRA
may lose its tax-exempt status and its assets may be deemed to have been
distributed to the individual in a taxable distribution on account of the
prohibited transaction but no excise tax will be imposed. Fiduciary shareholders
should consult their own legal advisors if they have any concern as to whether
the investment is a prohibited transaction.

Special Fiduciary and Prohibited Transactions Considerations

The Department of Labor, which has administrative responsibility over
ERISA plans as well as over IRAs and other Non-ERISA Plans, has issued a
regulation defining "plan assets." The regulation generally provides that when
an ERISA or Non-ERISA Plan or IRA acquires a security that is an equity interest
in an entity and that security is neither a "publicly offered security" nor a
security issued by an investment company registered under the Investment Company
Act of 1940, the ERISA plan's or Non-ERISA Plan's or IRA's assets include both
the equity interest and an undivided interest in each of the underlying assets
of the entity, unless it is established either that the entity is an operating
company or that equity participation in the entity by benefit plan investors is
not significant.

Each class of our shares--that is, our common shares and any class of
preferred shares that may be outstanding--must be analyzed separately to
ascertain whether it is a publicly offered security. The regulation defines a
publicly offered security as a security that is "widely held," "freely
transferable" and either part of a class of securities registered under the
Securities Exchange Act of 1934, or sold under an effective registration
statement under the Securities Act of 1933, provided the securities are
registered under the Securities Exchange Act of 1934 within 120 days after the
end of the fiscal year of the issuer during which the offering occurred. Each
class of our shares has been registered under the Securities Exchange Act of
1934.

The regulation provides that a security is "widely held" only if it is
part of a class of securities that is owned by 100 or more investors independent
of the issuer and of one another. However, a security will not fail to be
"widely held" because the number of independent investors falls below 100
subsequent to the initial public offering as a result of events beyond the
issuer's control. Our common shares have been widely held and we expect our
common shares to continue to be widely held. We expect the same to be true of
any class of preferred stock that we issue, but we can give no assurance in that
regard.

The regulation provides that whether a security is "freely
transferable" is a factual question to be determined on the basis of all
relevant facts and circumstances. The regulation further provides that, where a
security is part of an offering in which the minimum investment is $10,000 or
less, some restrictions on transfer ordinarily will not, alone or in
combination, affect a finding that these securities are freely transferable. The
restrictions on transfer enumerated in the regulation as not affecting that
finding include:

- any restriction on or prohibition against any transfer or
assignment which would result in a termination or
reclassification for federal or state tax purposes, or would
otherwise violate any state or federal law or court order;

17
-        any   requirement   that  advance  notice  of  a  transfer  or
assignment be given to us and any requirement that either the
transferor or transferee, or both, execute documentation
setting forth representations as to compliance with any
restrictions on transfer which are among those enumerated in
the regulation as not affecting free transferability,
including those described in the preceding clause of this
sentence;

- any administrative procedure which establishes an effective
date, or an event prior to which a transfer or assignment will
not be effective; and

- any limitation or restriction on transfer or assignment which
is not imposed by the issuer or a person acting on behalf of
the issuer.

We believe that the restrictions imposed under the declaration of trust
on the transfer of shares do not result in the failure of our shares to be
"freely transferable." Furthermore, we believe that at present there exist no
other facts or circumstances limiting the transferability of our common or
preferred shares which are not included among those enumerated as not affecting
their free transferability under the regulation, and we do not expect or intend
to impose in the future, or to permit any person to impose on our behalf, any
limitations or restrictions on transfer which would not be among the enumerated
permissible limitations or restrictions.

Assuming that each class of our shares will be "widely held" and that
no other facts and circumstances exist which restrict transferability of our
shares, we have received an opinion of counsel that such shares will not fail to
be "freely transferable" for purposes of the regulation due to the restrictions
on transfer of the shares under our declaration of trust and that under the
regulation the shares are publicly offered securities and our assets will not be
deemed to be "plan assets" of any ERISA plan, IRA or Non-ERISA Plan that invests
in our shares.

If our assets are deemed to be plan assets under ERISA, then

- the prudence standards and other provisions of Part 4 of Title
I of ERISA would be applicable to investments made by us;

- the person or persons having investment discretion over the
assets of ERISA plans which invest in us would be liable under
Part 4 of Title I of ERISA for investments made by us which do
not conform to the ERISA standards, unless the investment
decision was made by an advisor that has registered as an
investment adviser under the Investment Advisers Act of 1940
and other applicable conditions are satisfied, in which case
the registered advisor would potentially have such liability;

- transactions that we might enter into in the ordinary course
of its business and operation might constitute "prohibited
transactions" under ERISA and the Internal Revenue Code.

Item 2.  Properties

General. At December 31, 1998, approximately 29% of our total
investments were in senior housing properties, 67% were in office buildings and
4% were in hotels through our equity investment in HPT. We believe that the
physical plant of each of the facilities in which we have invested is suitable
and adequate for our present and any currently proposed uses. At December 31,
1998, we had real estate investments totaling $3.0 billion (at cost) in 256
properties that were leased to or operated by over approximately 700 tenants or
mortgagors, plus an investment of approximately $110.6 million (carrying value)
in approximately 8.8% of the common shares of HPT, which has investments in 170
hotel properties. At December 31, 1998, three properties with an aggregate cost
of $45.1 million were secured by two mortgages aggregating $24.8 million.

Item 3. Legal Proceedings

As previously disclosed, in early 1995 we commenced an action in
Florida state court to collect on a secured indemnity agreement from a former
tenant and mortgagor, together with certain related parties (collectively, the
"Former Tenant"). In May 1995 the Former Tenant filed a counterclaim and
third-party complaint against HRP and others including Messrs. Martin and
Portnoy, HRPT Advisors, Inc. and Sullivan & Worcester LLP, seeking, among other
things, to set aside the indemnity agreement and to recover substantial damages.
After a Massachusetts state court ordered the dispute to arbitration and a
Florida court stayed further proceedings pending arbitration, the Former Tenant
brought a separate action against HRP in the United States District Court for
the District of Massachusetts and realleged many of the same allegations made in
the counterclaims and third-party complaints previously brought by them in
response to HRP's original action, and adding allegations of violations of
Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5
promulgated thereunder and violations of 18 U.S.C ss. 1962 (RICO). In September
1996, the United States District Court for the District of Massachusetts ordered
the case brought by the Former Tenant dismissed and all disputes between the
Former Tenant and HRP referred to arbitration.

The arbitration is proceeding, and although the amount of damages
claimed by the Former Tenant is material, all claims of the Former Tenant
against HRP were dismissed in January of this year, except a basic claim for
common law fraud, which is scheduled for trial before the arbitrators in October
1999. The arbitrators' ruling, dismissing all but one claim against HRP, both
narrows substantially the scope of claims pending against HRP and diminishes
greatly the risk of the Former Tenant being able to hold HRP liable for (i)
attorneys fees and costs, or (ii) multiple damages, should the Former Tenant
prevail on its sole remaining claim against HRP. We continue to pursue our
indemnity claims in the arbitration.

As we have previously disclosed, certain related cases have also been
filed by creditors or assignees of the Former Tenant. The amounts of damages
claimed by the creditors or assignees of the Former Tenant are material. We will
defend the claims of the creditors or assignees of the Former Tenant in these
related proceedings, currently pending in Massachusetts Superior Court. The
outcome of the arbitration and the related pending claims and proceedings cannot
be predicted.

The Declaration of Trust provides that our Trustees shall be
indemnified in certain circumstances by HRP in connection with claims asserted
against them by reason of their status, subject to various limitations contained
in the Declaration of Trust. Were Messrs. Martin and Portnoy to be held liable
in the proceedings described above, they may have a claim for indemnification
from HRP.

No matters were submitted to a vote of shareholders during the fourth
quarter of the year covered by this Annual Report on Form 10-K.

PART II

Item 5. Market for Registrant's Common Stock and Related Stockholder Matters

Our Shares are traded on the New York Stock Exchange (symbol: HRP). The
following table sets forth for the periods indicated the high and low sale
prices for the Shares as reported in the New York Stock Exchange Composite
Transactions reports.

High Low
1997
First Quarter $20 5/8 $18
Second Quarter 19 17 3/4
Third Quarter 19 1/8 17 5/8
Fourth Quarter 20 5/16 18 9/16

1998
First Quarter 20 15/16 19 5/8
Second Quarter 20 1/4 17 7/8
Third Quarter 18 13/16 15 5/8
Fourth Quarter 17 1/8 14

The closing price of the Shares on the New York Stock Exchange on March
29, 1999 was $13 3/4.

As of March 5, 1999, there were approximately 5,951 holders of record of the
Shares, and we estimate that as of such date there were in excess of 145,000
beneficial owners of the Shares.

Dividends declared with respect to each period for the two most recent
fiscal years and the amount of such dividends and the respective annualized
rates are set forth in the following table.

Dividend Annualized
Per Share Dividend Rate
1997
First Quarter $.36 $1.44
Second Quarter .36 1.44
Third Quarter .37 1.48
Fourth Quarter .37 1.48

1998
First Quarter .38 1.52
Second Quarter .38 1.52
Third Quarter .38 1.52
Fourth Quarter .38 1.52

All dividends declared have been paid. We intend to continue to declare
and pay future dividends on a quarterly basis.

In order to qualify for the beneficial tax treatment accorded to REITs
by Sections 856 through 860 of the Internal Revenue Code, we are required to
make distributions to shareholders which annually will be at least 95% of our
taxable income. All distributions will be made by us at the discretion of the
Trustees and will depend on our earnings, our cash flow available for
distribution, our financial condition and other factors that the Trustees deem
relevant. We have in the past distributed, and intend to continue to distribute,
substantially all of our "real estate investment trust taxable income" to our
shareholders.

As previously reported, in 1997 we entered into an Agreement of Merger
(the "Merger Agreement") with Government Property Investors, Inc. ("GPI")
pursuant to which we agreed to acquire up to 30 office buildings


22
containing  approximately 3.4 million square feet, substantially all of which is
leased to various agencies of the United States government. The Merger Agreement
provided for us to acquire these properties in a series of closings in exchange
for our Shares. As of May 1998, the final closing under the Merger Agreement had
occurred, and we had issued 4,271,428 Shares to GPI and its successors and
assigns; however, the final number of Shares issuable in connection with the
Merger Agreement had not been determined. In February, 1999, we issued an
additional 256,246 Shares to GPI pursuant to the exemption from registration
contained in Section 4(2) of the Securities Act of 1933, as amended.

Item 6. Selected Financial Data

(1) Our Funds From Operations ("FFO") represents net income (computed in accordance with generally accepted accounting principles
("GAAP")), before gain or loss on sale of properties and extraordinary items, depreciation and other non-cash items and
includes HRP's pro rata share of HPT's FFO. Management considers FFO to be a measure of the financial performance of an equity
REIT that provides a relevant basis for comparison among REITs. FFO does not represent cash flow from operating activities (as
determined in accordance with GAAP) and should not be considered as an alternative to net income, as an indicator of our
financial performance or to cash flows as a measure of liquidity.

(2) Amounts represent dividends declared with respect to the periods shown. Distributions in excess of net income generally
constitute a return of capital.

Item 7. Management's  Discussion and Analysis of Financial Condition and Results
of Operations

The information required by this item is incorporated herein by
reference to the section entitled "Management's Discussion and Analysis of
Financial Condition and Results of Operations" in Item 5 of our Current Report
on Form 8-K dated March 5, 1999.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to risks associated with interest rate changes. We
manage our exposure to this market risk through our monitoring of available
financing alternatives. Our strategy to manage exposure to changes in interest
rates is unchanged from December 31, 1997. Furthermore, we do not foresee any
significant changes in our exposure to fluctuations in interest rates or in how
such exposure is managed in the near future. At December 31, 1998, our total
outstanding debt for fixed rate notes consisted of the following:

Amount Coupon Maturity

Unsecured senior notes:
$40.0 million 7.25% 2001
$160.0 million 6.875% 2002
$150.0 million 6.75% 2002
$164.9 million 7.50% 2003
$100.0 million 6.7% 2005
$143.0 million 8.5% 2013

Secured notes:
$13.1 million 8.00% 2008
$11.7 million 7.66% 2009

No principal repayments are due under the unsecured senior notes until
maturity. If, at maturity, the unsecured senior notes were to be refinanced at
interest rates which are 1/2 percentage point higher than shown above, our per
annum interest cost would increase by approximately $3.8 million. The secured
notes are secured by three of our office properties and require principal and
interest payments through maturity.

As of December 31, 1998, we had two series of senior unsecured notes
that were subject to floating interest rates; a $500.0 million bank credit
facility and another series of unsecured senior notes totaling $250.0 million.
Our bank credit facility bears interest at floating rates and matures in 2002.
At December 31, 1998, $400.0 million was available for drawing under our line of
credit and $100.0 million was outstanding. Our line of credit is available to
finance our acquisition commitments. As of December 31, 1998, our acquisition
commitments required approximately $21.7 million (plus closing costs) of cash.
Assuming these commitments were all funded with borrowings under our bank credit
facility, and assuming interest rates increased 1/2 percentage point, our
annualized interest cost would increase by approximately $108,500. Our unsecured
senior notes totaling $250.0 million bear interest at floating rates and mature
in 2007. Assuming interest rates increase 1/2 percentage point, our annualized
interest costs would increase by approximately $1.3 million.

Each of our obligations for borrowed money has provisions that allow us
to make repayments earlier than the stated maturity date. In some cases, we are
not allowed to make early repayment prior to a cutoff date and in other cases we
are allowed to make prepayments only at a premium to face value. In any event,
these prepayment rights may afford us the opportunity to mitigate the risk of
refinancing at maturity at higher rates, by refinancing at lower rates prior to
maturity.

From time to time, we may enter into contracts to hedge our interest
rate risk. As of December 31, 1998, we have not entered into any of these
contracts.

The market prices, if any, of each of our fixed rate obligations as of
December 31, 1998 are sensitive to changes in interest rates. Typically, if
market rates of interest increase, the current market price of a fixed rate
obligation will decrease. Conversely, if market rates of interest decrease, the
current market price of a fixed rate obligation typically will increase. Based
on the balances outstanding at December 31, 1998, a hypothetical immediate one
percentage point change in interest rates would change the fair value of our
fixed rate debt obligations by approximately $36.5 million (based on discounted
cash flow analysis).
