                Preliminary Prospectus dated September 9, 1998

PROSPECTUS

                                 144,328 SHARES
                             LIBERTY PROPERTY TRUST
                      COMMON SHARES OF BENEFICIAL INTEREST

      Liberty Property Trust (the "Company") is a self-administered and
self-managed Maryland real estate investment trust (a "REIT"). The Company
provides leasing, property management, acquisition, development, construction
management, design management and other related services for a portfolio which,
as of June 30, 1998, consisted of 540 industrial and office properties totaling
approximately 39.5 million leasable square feet. Such properties are located
principally in the Southeastern, Mid-Atlantic and Midwestern United States. As
of June 30, 1998, the Company also had 46 properties under development and owned
992 acres of land for future development.

      This Prospectus may be used only in connection with the resale, from time
to time, of up to 144,328 common shares of beneficial interest, $0.001 par value
(the "Common Shares"), of the Company by an entity (the "Selling Shareholder")
which has received such Common Shares (the "Shares") pursuant to an Agreement of
Sale and Purchase, dated June 3, 1998, as amended, (the "Agreement of Sale")
between Liberty Property Limited Partnership, a Pennsylvania limited
partnership, the operating partnership of the Company (the "Operating
Partnership") and the Selling Shareholder. The Shares may be sold from time to
time for the account of the Selling Shareholder. The Company will not receive
any proceeds from the sale of the Shares by the Selling Shareholder. The
expenses incurred in registering the Shares will be paid by the Company, except
for commissions, transfer taxes, legal fees, and certain other expenses
associated with the sale of the Shares, which will be paid by the Selling
Shareholder.     

     The Shares are to be issued by the Company to the Selling Shareholder
pursuant to the terms of the Agreement of Sale. The price at which the Shares
will be issued by the Company to the Selling Shareholder shall be $      . The
Company has agreed to indemnify the Selling Shareholder against certain
liabilities, including liabilities arising under the Securities Act of 1933, as
amended (the "Securities Act").

      The Selling Shareholder may offer, pursuant to this Prospectus, the Shares
to purchasers from time to time in transactions on the New York Stock Exchange
(the "NYSE"), in negotiated transactions, or otherwise, or by a combination of
these methods, at fixed prices that may be changed, at market prices prevailing
at the time of the sale, at prices related to such market prices or at
negotiated prices. The Selling Shareholder may effect these transactions by
selling the Shares to or through broker-dealers, who may receive compensation in
the form of discounts or commissions from the Selling Shareholder or from the
purchasers of the Shares for whom the broker-dealers may act as an agent or to
whom they may sell as a principal, or both. The Selling Shareholder and such
brokers-dealers may be deemed to be "underwriters" within the meaning of the
Securities Act, in connection with such sales. See "Plan of Distribution."

      The Common Shares are traded on the NYSE under the symbol "LRY." On
September 8, 1998, the last reported sale price of the Common Shares on the NYSE
was $22.00 per share.

      SEE "RISK FACTORS" BEGINNING ON PAGE 2 OF THIS PROSPECTUS FOR A DISCUSSION
OF CERTAIN MATTERS THAT SHOULD BE CONSIDERED BY PROSPECTIVE PURCHASERS OF THE
COMMON SHARES OFFERED HEREBY.

                                  RISK FACTORS

      Liberty Property Trust, a Maryland real estate investment trust (the
"Trust"), conducts substantially all of its operations through Liberty Property
Limited Partnership, a Pennsylvania limited partnership (the "Operating
Partnership"). Unless the context otherwise requires, as used in this
Prospectus, (i) the term "Operating Partnership" includes Liberty Property
Limited Partnership and its subsidiaries (and, where the context indicates, its
predecessor entities, Rouse & Associates, a Pennsylvania general partnership,
and certain affiliated entities (collectively, the "Predecessor")) and (ii) the
term "Company" includes the Trust and the Operating Partnership.

      This Prospectus contains or incorporates by reference forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933, as
amended (the "Securities Act"), and Section 21E of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"). The Company's actual results could
differ materially from those set forth in the forward-looking statements. For a
discussion of certain factors that might cause such a difference, in addition to
general investment risks and those factors incorporated by reference herein,
prospective investors should consider, among others, the following factors:

GENERAL REAL ESTATE INVESTMENT RISKS

      Dependence on Tenants; Renewal of Leases and Reletting of Space. The
Company's cash flow from operations will depend upon its ability to lease space
in its portfolio of properties (the "Operating Properties") and in its
properties currently under development (the "Development Properties" and,
together with the Operating Properties, the "Properties") on economically
favorable terms. Upon the expiration of leases, such leases may not be renewed,
the space may not be relet or the terms of renewal or reletting (including
rental rates, the cost of leasing commissions, required renovations and
concessions to tenants) may be less favorable than current lease terms. If any
or all of these events occur, the Company's cash flow from operations and
ability to make expected distributions to shareholders could be adversely
affected. The Company's cash flow from operations also would be adversely
affected if tenants leasing a significant amount of space fail to pay rent,
become bankrupt or, if for any other reason, such rents could not be collected.
Moreover, to the extent a tenant defaults on a lease, the Company may experience
delays and costs in enforcing its rights as lessor. Further, the Company may be
adversely affected by various facts and events over which the Company will have
no control, such as a change in the demand in the markets in which the
Properties are located, the possible unavailability of prospective tenants and
the possibility of economic or physical decline of the areas in which the
Properties are located or physical damage to the Properties that would make them
less attractive to tenants.

      Risks of Acquisition, Development and Construction Activities. The Company
intends to continue acquisition and development of industrial and office
properties. Acquisitions of additional properties and development activities
entail risks that investments will fail to perform in accordance with
expectations. With respect to the Company's development activities, such
development opportunities may be abandoned, construction costs of any property
may exceed original or budgeted estimates (possibly making the property
uneconomical) and construction and lease-up may not be completed on schedule,
resulting in increased debt service expense and construction costs. Development
activities are also subject to risks relating to the inability to obtain, or
delays in


                                        2
<PAGE>   6
obtaining, all necessary zoning, land-use, building, occupancy and other
required governmental permits and authorizations.

      The Company anticipates that future acquisitions and developments will be
financed, in whole or in part, under the Company's $325 million credit facility
(the "Credit Facility"), through other forms of secured or unsecured financing
or through utilization of access to capital markets. Such financings may result
in the risk that, upon completion of construction, permanent financing for newly
developed commercial properties may not be available or may be available only on
disadvantageous terms. If financing is not available on acceptable terms for new
acquisitions or developments undertaken without permanent financing, further
acquisitions and development might be curtailed, cash available for distribution
might be adversely affected and foreclosures on newly developed or acquired
properties could occur. Further, if any particular property is not successful,
the Company's losses could exceed its investment in the property.

      Competition. There are numerous developers and real estate companies that
compete with the Company in seeking land for development, properties for
acquisition and tenants for properties. The Company may be adversely affected by
the fact that the availability of land for development within the Company's
markets continues to diminish, as does the availability of high quality
properties for acquisition within the Company's markets and elsewhere.

      Possible Environmental Liabilities. Under various federal, state and local
laws, ordinances and regulations relating to the protection of the environment
(collectively, "Environmental Laws"), a current or previous owner or operator of
real estate may be liable for the cost of removal or remediation of certain
hazardous or toxic substances disposed, stored, released, generated,
manufactured or discharged from, on, at, onto, under or in such property.
Environmental Laws often impose such liability without regard to whether the
owner or operator knew of, or was responsible for, the presence or release of
such hazardous or toxic substances. In addition, the presence of any such
substances, or the failure to properly remediate such substances when present,
released or discharged, may adversely affect the owner's ability to sell or rent
such property or to borrow using such property as collateral. The cost of any
required remediation and the liability of the owner or operator therefor as to
any property is generally not limited under such Environmental Laws and could
exceed the value of the property and/or the aggregate assets of the owner or
operator. In addition to any action required by federal, state or local
authorities, the presence of hazardous or toxic substances on any of the
Properties, or on any properties acquired hereafter, could result in private
plaintiffs bringing claims for personal injury or other causes of action. In
connection with the ownership and operation of the Properties, and of any
properties acquired hereafter, the Company may be potentially liable for
remediation, release or injury. Further, various Environmental Laws impose on
owners or operators the requirement of on-going compliance with rules and
regulations regarding business-related activities that may affect the
environment. Failure to comply with such requirements could result in difficulty
in the lease or sale of any affected Property or the imposition of monetary
penalties and fines in addition to the costs required to attain compliance.


                                        3
<PAGE>   7
INDEBTEDNESS

      Required payments on mortgages and other indebtedness generally are not
reduced if the economic performance of any property declines. If such a decline
occurs, the Company's income, funds from operations and cash available for
distribution to shareholders will be adversely affected. If the payments under
such indebtedness cannot be made, the Company could sustain a loss, which may
include foreclosures by or judgments against the Company in favor of mortgagees.
Further, instruments evidencing certain of the Company's indebtedness, including
the Operating Partnership's Exchangeable Subordinated Debentures due 2001 (the
"Exchangeable Subordinated Debentures") and the Credit Facility, contain
cross-default and/or cross-acceleration provisions. Depending on the principal
amount of the Exchangeable Subordinated Debentures that are exchanged for Common
Shares, the Company may not have accumulated sufficient cash to repay the
principal due on the Exchangeable Subordinated Debentures upon their maturity
and may therefore be required to meet its obligations through refinancings.
Additionally, certain of the Company's indebtedness, including indebtedness
under the Credit Facility, bears interest at variable rates and, therefore,
exposes the Company to the risk of increasing interest rates. There can be no
assurance that the Company will be able to refinance this or any other
indebtedness.

RISK OF ENTRY INTO NEW MARKETS

      The Company's business strategy contemplates expanding the Company's
operations into additional new markets. In determining whether to enter a new
market, management considers demographics, job growth, employment, real estate
fundamentals and competition. There can be no assurance that the Company will be
successful in its effort to identify new markets that will afford it the
opportunity for favorable results or that the Company will be able to achieve
such results in those markets.

DEPENDENCE ON PRIMARY MARKETS

      The Properties are located principally in the Southeastern, Mid-Atlantic
and Midwestern United States. The Company's performance is, therefore, dependent
upon economic conditions in these geographic areas. Like much of the country,
the Southeastern, Mid-Atlantic and Midwestern United States have been subject to
periods of economic decline.

TAX RISKS

      Adverse Consequences of the Failure to Qualify as a REIT. Although the
Company believes that the Company qualifies as a REIT, no assurance can be given
that the Company in fact has qualified, or will remain qualified, as a REIT.
Qualification as a REIT involves the application of highly technical and complex
provisions of the Internal Revenue Code of 1986, as amended (the "Code"), for
which there are only limited judicial or administrative interpretations. The
complexity of these provisions and of the applicable income tax regulations that
have been promulgated under the Code (the "Treasury Regulations") is greater in
the case of a REIT that holds its assets in partnership form. Moreover, no
assurance can be given that new legislation, regulations, administrative
interpretations or court decisions will not significantly alter the tax laws
regarding qualification as a REIT or the federal income tax consequences of such
qualification, possibly with retroactive effect. At the present time however,
the Company has no reason to expect a change in


                                        4
<PAGE>   8
such tax laws that would significantly and adversely affect the Company's
ability to qualify and operate as a REIT.

      If in any taxable year the Company were to fail to qualify as a REIT, the
Company would not be allowed a deduction for distributions to shareholders in
computing its taxable income and would be subject to federal income tax on its
taxable income at regular corporate rates. Moreover, unless entitled to relief
under certain statutory provisions, the Company also would be disqualified from
treatment as a REIT for the four taxable years following the year in which such
qualification was lost, and if the Company subsequently requalified as a REIT,
it may be required to pay a full corporate-level tax on any unrealized gain in
its assets as of the date of requalification and to make distributions at that
time equal to any earnings accumulated during the period of non-REIT status. As
a result, such additional taxes would reduce the funds available for
distribution to shareholders for each of the years involved. In addition, during
the period in which the Company had lost its REIT status, the Company would no
longer be required by the Code to make any distributions to shareholders.
Although the Company intends to continue to operate in a manner designed to
qualify as a REIT, it is possible that future economic, market, legal, tax or
other considerations may cause the Company's trustees, with the consent of the
holders of a majority of the voting interest of all outstanding Common Shares,
to revoke the election for the Company to qualify as a REIT. For further federal
income tax considerations, including a discussion of the qualification of the
Operating Partnership as a partnership for federal income tax purposes, see
"Federal Income Tax Considerations with Respect to the Trust and the Operating
Partnership -- Classification as a Partnership."

      Tax Consequences to Certain Officers and Trustees. Certain officers and
trustees of the Company own Units which may be exchanged for Common Shares.
Prior to the exchange of Units for Common Shares, officers and trustees of the
Company who own Units may suffer different and more adverse tax consequences
than holders of Common Shares upon the sale of certain of the Properties, the
refinancing of debt associated with those properties or in connection with a
proposed tender offer or merger involving the Company and, therefore, such
individuals and the Company, as partners in the Operating Partnership, may have
different objectives regarding the appropriate terms of any such transaction.

LIMITATIONS ON CHANGES IN CONTROL

      Ownership Limit. In order to protect its status as a REIT, the Company
must satisfy certain conditions, including the condition that no more than 50%
in value of its outstanding shares of beneficial interest may be owned, directly
or indirectly, by five or fewer individuals. To this end, the Declaration of
Trust, among other things, prohibits any holder from owning more than 5.0% of
its outstanding shares of beneficial interest without the consent of the Board
of Trustees of the Company (the "Board of Trustees"). This limitation may have
the effect of precluding acquisition of control of the Company by a third party
without the consent of the Board of Trustees.

      Shareholder Rights Plan. Under the Company's Shareholder Rights Plan (the
"Plan"), each Right (as defined in the Plan), which is attached to each Common
Share entitles the holder thereof (other than an Acquiring Person (as defined in
the Plan)) to purchase from the Trust, under certain conditions, one
one-thousandth of a Series A Junior Participating Preferred Share, $0.0001 par
value, of the Trust for $100, subject to adjustment. Each Right may also, under
certain conditions,


                                        5
<PAGE>   9
entitle the holder thereof (other than an Acquiring Person) to receive Common
Shares, or common shares of an entity acquiring the Company, or other
consideration, each having a value equal to twice the exercise price of each
Right ($200). The Trust has designated 200,000 Series A Junior Participating
Preferred Shares and has reserved such shares for issuance under the Plan. The
Rights are redeemable by the Trust at a price of $0.0001 per Right. If not
exercised or redeemed, all Rights will expire on December 31, 2007. The
description and terms of the Rights are set forth in the Rights Agreement, dated
as of December 17, 1997, between the Trust and Bank Boston, N.A., as Rights
Agent.

      Staggered Board and Nominating Procedures. The Board of Trustees has three
classes of trustees. The term of office of one class expires each year. Trustees
for each class are elected for three-year terms upon the expiration of the
respective class' term. Any nominee for trustee must have been selected pursuant
to the nominating provisions contained in the Declaration of Trust and By-Laws.
The staggered terms for trustees and such nominating procedures may affect the
shareholders' ability to take control of the Company, even if a change in
control were in the shareholders' interest.

      Preferred Shares. The Declaration of Trust authorizes the Board of
Trustees to issue preferred shares and to establish the preferences and rights
of any shares issued. The issuance of preferred shares could have the effect of
delaying or preventing a change of control of the Company, even if a change in
control were in the shareholders' interest.

ADVERSE IMPACT OF INCREASING MARKET INTEREST RATES ON MARKET PRICE

      One of the factors that may influence the price of the Common Shares in
public markets is the annual yield on the Common Share price paid from dividend
distributions by the Company. Thus, an increase in market interest rates may
lead purchasers of Common Shares to demand a higher annual yield, which could
adversely affect the market price of the Common Shares.

FORWARD-LOOKING STATEMENTS

      The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for forward-looking statements. Certain materials filed or to be filed
by the Company with the Commission and incorporated by reference herein contain
statements that are or will be forward-looking, such as statements relating to
acquisitions (including related pro forma financial information) and other
business development activities, future capital expenditures, financing sources
and availability and the effects of regulations (including environmental
regulation) and competition. Such forward-looking information involves important
risks and uncertainties that could significantly affect anticipated results in

                                   THE COMPANY

      Liberty Property Trust is a self-administered and self-managed real estate
investment trust formed in 1994. The Company provides leasing, property
management, acquisition, development, construction management, design management
and other related services for the Operating Properties which, as of June 30,
1998, consisted of 363 industrial and 177 office properties totaling
approximately 39.5 million leasable square feet. The Operating Properties
were approximately 95.0% leased to approximately 1,800 tenants as of June 30,
1998. As of the same date, the Company also had 46 Development Properties,
expected to generate approximately 5.0 million leasable square feet. As of
June 30, 1998, the Company also owned 992 acres of land, anticipated by the
Company to be capable of supporting, as and when developed, approximately
nine million leasable square feet. The Properties and such land are located
principally within the Southeastern, Mid-Atlantic and Midwestern United States.

      During the six months ended June 30, 1998, the Company increased its total
leasable square footage of industrial and office space by approximately 21.7%
through the acquisition of 88 properties totaling approximately 6.4 million
leasable square feet, the disposition of five properties containing 193,000
leasable square feet, and the completion of the development of 15 properties
totaling approximately 782,000 leasable square feet. In the same period, the
Company also increased its ownership of land for future development by 35 acres
as a result of the purchase of 65 acres, the disposition of 10 acres and the
development of 120 acres.

      The Company's executive offices are located at 65 Valley Stream Parkway,
Malvern, Pennsylvania 19355. The telephone number is (610) 648-1700. The Company
maintains offices in each of its principal markets.

                                RECENT ACTIVITIES

RECENT FINANCING ACTIVITIES

      On August 4, 1998, the Company consummated a public offering of 3,960,820
Common Shares at a price of $25.25 per share. The aggregate net proceeds to the
Company from such offering were approximately $99.2 million.

RECENT ACQUISITION AND  DEVELOPMENT ACTIVITIES

      Since July 1, 1998, through August 31, 1998, the Company purchased 49
industrial and office properties comprising approximately 1.6 million leasable
square feet for a Total Investment (as defined below) of $124.0 million. Of
these 49 properties, 43 were industrial properties that contain approximately
1.1 million leasable square feet for a Total Investment of $67.2 million and 6
were office properties that contain approximately 503,000 leasable square feet
for a Total Investment of $56.8 million. The "Total Investment" for a property
is defined as the property's purchase price plus closing costs and management's
estimate, as determined at the time of acquisition, of the cost of necessary
building improvements in the case of acquisitions, or land costs and land and
building improvement costs in the case of development projects, and where
appropriate, other development costs and carrying costs required to reach rent
commencement.

      As of August 31, 1998, the Company's portfolio consisted of 594 industrial
and office properties totaling approximately 41.7 million leasable square feet.
As of August 31, 1998, the Company also had 45 properties under development and
owned 1,078 acres of land for future development.

PENDING ACQUISITIONS

      As of August 31, 1998, the Company had entered into agreements to acquire
three industrial and office properties (the "Pending Acquisitions) which the
Company considered probable of closing as of the date of this Prospectus. The
Pending Acquisitions aggregate approximately 145,000 leasable square feet and
the aggregate Total Investment in the properties is estimated to be $10.4
million.

      The purchase of each of the properties comprising the Pending Acquisitions
is subject to certain contingencies, including completion of due diligence
satisfactory to the Company and other customary conditions. Accordingly, there
can be no assurance that the Company will acquire any or all of such properties
or that the acquisitions of such properties will be consummated for the
estimated Total Investment.

                        FEDERAL INCOME TAX CONSIDERATIONS
             WITH RESPECT TO THE TRUST AND THE OPERATING PARTNERSHIP

      The following summary of the material federal income tax considerations
with respect to the Trust and the Operating Partnership regarding the offering
of the Common Shares is based on current law, is for general information only
and is not intended as tax advice. The tax treatment of a holder of any of the
Common Shares will vary depending on such holder's particular situation, and
this summary is addressed only to holders that hold the Common Shares as capital
assets and does not attempt to address all aspects of federal income taxation
relating to holders of the Common Shares. Nor does it discuss all of the aspects
of federal income taxation that may be relevant to certain types of holders
(including insurance companies, tax-exempt entities, financial institutions or
broker-dealers, foreign corporations and persons who are not citizens or
residents of the United States) who are subject to special treatment under the
federal income tax laws.

      EACH PROSPECTIVE PURCHASER OF COMMON SHARES IS ADVISED TO CONSULT HIS OR
HER OWN TAX ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE
PURCHASE, OWNERSHIP AND SALE OF THE COMMON SHARES AND OF THE TRUST'S ELECTION TO
BE TAXED AS A REAL ESTATE INVESTMENT TRUST, INCLUDING THE FEDERAL, STATE, LOCAL,
FOREIGN AND OTHER TAX CONSEQUENCES OF SUCH PURCHASE, OWNERSHIP, SALE AND
ELECTION AND OF POTENTIAL CHANGES IN APPLICABLE TAX LAWS.

TAXATION OF THE TRUST

      Management of the Trust believes that, commencing with the Trust's taxable
year ended December 31, 1994, the Trust has been organized and operated in such
a manner as to qualify as a REIT under Sections 856 through 860 of the Code. The
Trust intends to continue to operate in such a manner as to qualify for taxation
as a REIT in the future, but no assurance can be given that it has or will
remain qualified.

      The sections of the Code relating to qualification and operation as a REIT
are highly technical and complex. The following sets forth the material aspects
of the Code sections that govern the federal income taxation of a REIT. This
summary is qualified in its entirety by the applicable Code provisions, rules
and regulations promulgated thereunder, and administrative and judicial
interpretations thereof.

      Wolf, Block, Schorr and Solis-Cohen LLP has opined that, commencing with
the Trust's taxable year ended December 31, 1994, the Trust has been organized
and operated in conformity with the requirements for qualification and taxation
as a REIT under the Code, and its proposed method of operation will enable it to
continue to meet the requirements for qualification and taxation as a REIT under
the Code for future taxable periods. It must be emphasized that the opinion of
Wolf, Block, Schorr and Solis-Cohen LLP is based on certain assumptions and
representations made by the Trust and the Operating Partnership as to factual
matters. Moreover, such qualification and taxation as a REIT depend upon the
Trust's future ability to meet, through actual annual operating results, certain
distribution levels, the diversity of stock ownership requirements and the
various other qualification tests imposed under the Code discussed below, the
results of which may not be reviewed by Wolf, Block, Schorr and Solis-Cohen LLP.
Accordingly, no assurance can be given


                                       11
<PAGE>   15
that the actual results of the Trust's operation for any particular taxable year
will satisfy such requirements. For a discussion of the tax consequences of
failure to qualify as a REIT, see "-- Failure to Qualify."

      As a REIT, the Trust generally is not subject to federal corporate income
taxes on its net income that it currently distributes to shareholders. This
treatment substantially eliminates the "double taxation" (at the corporate and
shareholder levels) that generally results from investment in a corporation.
However, the Trust will be subject to federal income or excise tax as follows.
First, the Trust will be taxed at regular corporate rates on any undistributed
real estate investment trust taxable income, including undistributed net capital
gains. Second, under certain circumstances, the Trust may be subject to the
"alternative minimum tax" on its items of tax preference. Third, if the Trust
has (i) net income from the sale or other disposition of "foreclosure property"
(generally property acquired by a REIT upon the default by a debtor with respect
to indebtedness secured by the property or upon the default by a lessee where
the REIT was the lessor) which is held primarily for sale to customers in the
ordinary course of business or (ii) other nonqualifying income from foreclosure
property, it will be subject to tax at the highest corporate tax rate on such
income. Fourth, if the Trust has net income from "prohibited transactions"
(which are, in general, certain sales or other dispositions of property held
primarily for sale to customers in the ordinary course of business, other than
foreclosure property and, effective for the Trust's taxable year ending December
31, 1998, dispositions of property that occur due to involuntary conversion),
such income will be subject to a 100% tax. Fifth, if the Trust should fail to
satisfy the 75% gross income test or the 95% gross income test (discussed
below), but has nonetheless maintained its qualification as a REIT because
certain other requirements have been met, it will be subject to a 100% tax on an
amount equal to (i) the gross income attributable to the greater of the amount
by which the Trust fails the 75% test or the 95% test in the taxable year,
multiplied by (ii) a fraction generally intended to reflect the Trust's
profitability. Sixth, if the Trust should fail to distribute during each
calendar year at least the sum of (i) 85% of its REIT ordinary income for such
year, (ii) 95% of its REIT capital gain net income for such year, and (iii) any
undistributed taxable income from prior periods, the Trust would be subject to a
4% excise tax on the excess of such required distribution over the amounts
actually distributed. Seventh, if the Trust acquires any asset from a C
corporation (i.e., generally a corporation subject to full corporate-level tax)
in a transaction in which the basis of the asset in the Trust's hands is
determined by reference to the basis of the asset (or any other property) in the
hands of such C corporation, and the Trust recognizes gain on the disposition of
such asset during the 10-year period following acquisition of the asset, then,
pursuant to guidelines issued by the Internal Revenue Service (the "IRS"), to
the extent of the "built-in gain" (the excess of the fair market value of the
asset on the date acquired over its adjusted tax basis at that date), such gain
will be subject to tax at the highest regular corporate rate. The result
described above with respect to the recognition of built-in gain assumes the
Trust is eligible to make, and makes, an election pursuant to IRS Notice 88-19.

REQUIREMENTS FOR QUALIFICATION

      The 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 as a domestic corporation, but
for Sections 856 through 860 of the Code; (4) that is neither a financial
institution nor an insurance Trust subject to certain provisions of the Code;
(5) the beneficial ownership of


                                       12
<PAGE>   16
which is held by 100 or more persons; (6) during the last half of each taxable
year not more than 50% in value of the outstanding stock of which is owned,
directly or indirectly, by five or fewer individuals (as defined in the Code to
include certain entities as "individuals" for these purposes); and (7) which
meets certain other tests, described below, regarding the nature of its income
and assets. The 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. For purposes of determining stock
ownership under the rule limiting ownership by five or fewer individuals, REIT
shares held by a pension fund generally are treated as held proportionately by
its beneficiaries and certain other attribution rules will apply.

      The Trust has satisfied and will continue to satisfy conditions (1)
through (6) above. In making the "five or fewer individuals" determination, if
treating interests in the Operating Partnership that can be converted into
shares of the Trust as converted into outstanding shares would cause the Trust
to fail that test, the interests are deemed to have been converted. In addition,
the Declaration of Trust provides for restrictions regarding transfer of its
shares, in order to assist the Trust in continuing to satisfy the share
ownership requirements described in (5) and (6) above. Such transfer
restrictions are included in the Declaration of Trust, filed as an exhibit to a
report incorporated by reference herein. See "Incorporation of Certain Documents
by Reference."

      Code Section 856(i) provides that a corporation which is a "qualified REIT
subsidiary" is not to be treated as a separate corporation, and all assets,
liabilities, and items of income, deduction, and credit of a "qualified REIT
subsidiary" are treated as assets, liabilities, and such items (as the case may
be) of the REIT. A qualified REIT subsidiary is defined as a corporation 100% of
the stock of which is held by the REIT at all times during the existence of the
corporation. Effective for the Trust's taxable year ending December 31, 1998, a
qualified REIT subsidiary will be defined as any corporation 100% of the stock
of which is held by the REIT, regardless of whether the REIT has held such
corporation's stock at all times during its existence. Thus, in applying the
requirements described herein, the Trust's "qualified REIT subsidiaries" are
ignored, and all assets, liabilities, and items of income, deduction, and credit
of such subsidiaries will be treated as assets, liabilities and items of the
Trust.

      In the case of a REIT which is a partner in a partnership, Treasury
Regulations provide that the REIT will be deemed to own its proportionate share
of the assets of the partnership and will be deemed to be entitled to the income
of the partnership attributable to such share. In addition, the character of the
assets and gross income of the partnership retain the same character in the
hands of the REIT for purposes of Section 856 of the Code, including satisfying
the gross income tests and the asset tests described below. Thus, the Trust's
proportionate share of the assets, liabilities and items of income of the
Operating Partnership and the other partnerships through which the Trust's
properties are owned (the "Property Partnerships") will be treated as assets,
liabilities and items of income of the Trust for purposes of applying the
requirements described herein. The references to the gross income or assets of
the Trust, as discussed immediately below in "Income Tests" and "Assets Tests,"
include the Trust's proportionate share of the gross income or assets, as the
case may be, of the Operating Partnership and the Property Partnerships.


                                       13
<PAGE>   17
INCOME TESTS

      For the Trust to maintain its qualification as a REIT, the Trust must
satisfy three separate tests based on the nature of the underlying gross income.
These requirements must be satisfied annually. First, at least 75% of the
Trust's gross income (excluding gross income from prohibited transactions) for
each taxable year must consist of income derived directly or indirectly from
investments relating to real property or mortgages on real property (including
"rents from real property" and, in certain circumstances, interest) or certain
types of "qualified temporary investment income." Second, at least 95% of the
Trust's gross income (excluding gross income from prohibited transactions) for
each taxable year must be derived from such real property investments, and from
dividends, other types of interest, and gain from the sale or disposition of
stock or securities or from any combination of the foregoing. Third, for its
taxable years ending on or before December 31, 1997, short-term gain from the
sale or other disposition of stock or securities, gain from prohibited
transactions and gain on the sale or other disposition of real property held for
less than four years (apart from involuntary conversions and sales of
foreclosure property) must represent less than 30% of the Trust's gross income
(including gross income from prohibited transactions) for each taxable year.

      Rents received by the Trust will qualify as "rents from real property" in
satisfying the gross income requirements for a REIT described above provided
that several conditions are met. First, the amount of rent must not be based in
whole or in part on the income or profits of any person. However, an amount
received or accrued generally is not excluded from the term "rents from real
property" solely by reason of being based on a fixed percentage or percentages
of receipts or sales. Special rules apply where the tenant is a sublessor with
respect to property which permits a REIT to receive rent determined by reference
to the income or profits of the tenant in some cases. Second, the Code provides
that rents received from a tenant do not qualify as "rents from real property"
in satisfying the gross income tests if the REIT, directly or through the
applicable ownership attribution rules, owns 10% or more of such tenant (a
"Related Party Tenant"). Although the Trust may lease portions of its properties
to tenants that may constitute Related Party Tenants, the Trust does not believe
that the rents attributable to such leases would cause the Trust to fail to
satisfy the 75% or 95% gross income tests. Third, if rent attributable to
personal property leased in connection with a lease of real property is greater
than 15% of the total rent received under the lease, the portion of rent
attributable to such personal property will not qualify as "rents from real
property." The Trust does not anticipate that the rent attributable to the
personal property leased in connection with the real property will be greater
than 15% of the total rent received under the lease or, if it was as to any
particular lease or group of leases, that the rent attributable to the personal
property would cause the Trust to fail to satisfy the 75% or 95% gross income
tests. Finally, in order for rents received to qualify as "rents from real
property," the REIT generally must not operate or manage the property or furnish
or render services to the tenants of such property, other than through an
independent contractor that is adequately compensated and from whom the REIT
derives no revenue; provided, however, that the Trust may directly perform
services "usually and customarily" rendered in connection with the rental of
space for occupancy only and that are not otherwise considered "rendered to the
occupant" of the property. The Trust has represented that it does not and will
not knowingly (i) charge rent for any property that is based in whole or in part
on the income or profits of any person or (ii) directly perform services
considered to be rendered to the occupant of property, other than services
usually and customarily rendered in connection with the rental of space for
occupancy only.


                                       14
<PAGE>   18
      The Trust is a self-managed REIT; i.e., the Operating Partnership performs
all of the management and leasing functions with respect to the properties it
owns, provided that the services called for do not cause the rents received with
respect to those leases to fail to qualify as "rents from real property." To the
extent that the services provided are not "usual and customary" under the
foregoing rules, the Trust will employ a qualifying independent contractor to
render the services. The Trust may provide property management and leasing
services to third parties and will provide services to an affiliated entity for
a fee.

      Effective for the Trust's taxable years beginning on or after January 1,
1998, the Trust may render a de minimis amount of impermissible services to
tenants, or in connection with the management of a property (together,
"Impermissible Services"), without having otherwise qualifying rents from the
property being disqualified as "rents from real property." In order to qualify
for this de minimis exception, the amount received by the Trust for
Impermissible Services with respect to any property for any taxable year may not
exceed 1% of all amounts received or accrued by the Trust during such taxable
year with respect to such property. For purposes of the foregoing, the amount
treated as "received" by the Trust for Impermissible Services will not be less
than 150% of the Trust's direct cost in rendering such service. However, the
amount of any income that the Trust receives for Impermissible Services will not
be treated as "rents from real property" for purposes of the gross income tests.
The Operating Partnership may receive fees in consideration of the performance
of management and administrative services with respect to any properties that
are not owned entirely by the Operating Partnership. Although a portion of such
management and administrative fees generally will not constitute "qualifying
income" for purposes of the 75% and 95% gross income tests, the Trust Management
believes that the aggregate amount of such fees, if any (plus any income from
Impermissible Services and other nonqualifying income), in any taxable year will
not cause the Trust to fail the 75% and 95% gross income tests.

      For purposes of the gross income test, the term "interest" generally does
not include any amount received or accrued (directly or indirectly) if the
determination of such amount depends in whole or in part on the net income or
profits of any person. However, an amount received or accrued generally will not
be excluded from the term "interest" solely by reason of being based on a fixed
percentage or percentages of receipts or sales.

      Generally, the failure to satisfy either or both of the 75% and 95% gross
income tests will cause the REIT status of the Trust to terminate with the
taxable year in which the failure occurs. Relief from the adverse consequences
of such failure is available if the Trust's failure to meet such tests was due
to reasonable cause and not willful neglect, the Trust attaches a schedule of
the nature and the sources of its gross income to its income tax return, and any
incorrect information set forth on the schedule is not due to fraud with intent
to evade tax. It is not possible to state whether, in all circumstances, the
Trust would be entitled to the benefit of these relief provisions. As discussed
above in "Taxation of the Trust," even if these relief provisions apply, a tax
would be imposed with respect to the excess of 75% or 95% of the Trust's gross
income over the Trust's qualifying income in the relevant category, whichever is
greater.

<PAGE>   19
ASSET TESTS

      The Trust, at the close of each quarter of its taxable year, must also
satisfy three tests relating to the nature of its assets. First, at least 75% of
the value of the Trust's total assets must be represented by real estate assets
(including (i) its allocable share of real estate assets held by partnerships in
which the Trust owns an interest or held by "qualified REIT subsidiaries" of the
Trust and (ii) stock or debt instruments held for not more than one year
purchased with the proceeds of a stock offering or long-term (at least five
years) debt offering of the Trust), cash, cash items and governmental
securities. Second, not more than 25% of the Trust's total assets may be
represented by securities other than those in the 75% asset class. Third, of the
investments included in the 25% asset class, the value of any one issuer's
securities owned by the Trust may not exceed 5% of the value of the Trust's
total assets and the Trust may not own more than 10% of any one issuer's
outstanding voting securities (other than the stock of a qualified REIT
subsidiary, of which the REIT is required to own all of the stock, or of another
real estate investment trust).

      The Operating Partnership owns 8.0% of the voting common stock and 100% of
the non-voting common stock of Liberty Property Development Corp. ("Liberty
Development") and none of the voting common stock and 100% of the non-voting
common stock of Liberty Property Development Corp.-II ("Development-II" and,
together with Liberty Development, the "Development Companies"). By virtue of
its ownership of partnership interests in the Operating Partnership, the Trust
owns its pro rata shares of the common stock of the Development Companies. The
Operating Partnership does not own more than 10% of the voting securities of
either of the Development Companies and, therefore, the Trust will not own more
than 10% of the voting securities of either of the Development Companies. The
IRS could contend that the Trust, through its interest in the Operating
Partnership, should be viewed as owning more than 10% of the voting securities
of either of the Development Companies because of its substantial economic
positions in the Development Companies and because of the close business
relationships between it and each of the two Development Companies. If such
contention were sustained, the Trust would not qualify as a REIT. The Operating
Partnership does not possess the requisite power to elect or designate a member
of the respective Boards of Directors of the Development Companies, and there is
no understanding or arrangement permitting the Trust to exercise voting power or
control over the voting common stock of either of the Development Companies not
owned by it. Accordingly, Wolf, Block, Schorr and Solis-Cohen LLP and the Trust
do not believe that the Trust will be viewed as owning in excess of 10% of the
voting securities of either of the Development Companies. Based on its analysis
of the estimated value of the securities of the subsidiaries to be owned by the
Operating Partnership relative to the estimated value of the other assets to be
owned by the Operating Partnership, the Trust has determined that its respective
pro rata shares of the securities of the Development Companies held by the
Operating Partnership do not exceed 5% of the total value of the Trust's assets.
No independent appraisals will be obtained to support this conclusion and Wolf,
Block, Schorr and Solis-Cohen LLP, in rendering its opinion as to the
qualification of the Trust as a REIT, is relying solely on the representations
of the Trust regarding the values of the Development Companies. The 5%-of-value
requirement must be satisfied each time the Trust increases its ownership of
securities of either of the Development Companies (including as a result of
increasing its interest in the Operating Partnership as its limited partners
exercise their conversion rights). Although the Trust plans to take steps to
insure that it satisfies the 5% value test for any quarter with respect to which
retesting is to occur, there can be no assurance that such steps will


                                       16
<PAGE>   20
always be successful or will not require a reduction in the Operating
Partnership's overall interest in either of the Development Companies.

      After initially meeting the asset tests at the close of any quarter, the
Trust will not lose its status as a REIT for failure to satisfy the asset tests
at the end of a later quarter solely by reason of changes in asset values. If
the failure to satisfy the asset tests results from an acquisition of securities
or other property during a quarter, the failure can be cured by disposition of
sufficient non-qualifying assets within 30 days after the close of any quarter
as may be required to cure any non-compliance.

ANNUAL DISTRIBUTION REQUIREMENTS

      To qualify as a REIT, the Trust is required to distribute dividends (other
than capital gain dividends) to its stockholders in an amount at least equal to
(A) the sum of (i) 95% of the "REIT taxable income" of the Trust (computed
without regard to the dividends paid deduction and the Trust's net capital gain)
and (ii) 95% of the net taxable income (after tax), if any, from foreclosure
property, minus (B) the sum of certain items of noncash income. Such
distributions must be paid in the taxable year to which they relate, or in the
following taxable year if declared before the Trust timely files its tax return
for such year and if paid on or before the first regular dividend payment after
such declaration. To the extent the Trust does not distribute all of the net
capital gain or distributes at least 95%, but less than 100%, of its "REIT
taxable income," as adjusted, it will be subject to tax on the undistributed
amount at the regular corporate tax rates applicable to such income.
Furthermore, if the Trust should fail to distribute during each calendar year at
least the sum of (i) 85% of its REIT ordinary income for such year, (ii) 95% of
its REIT capital gain income for such year, and (iii) any undistributed taxable
income from prior periods, the Trust would be subject to a 4% excise tax on the
excess of such required distribution over the amounts actually distributed.

      The Trust has made, and intends to make, timely distributions to its
shareholders in amounts sufficient to satisfy the annual distribution
requirements. The Operating Partnership, as the general partner of each Property
Partnership, is authorized under the various partnership agreements to cause
distributions to be made to their respective partners of all available cash to
permit the Trust to meet the annual distribution requirement. It is possible
that, from time to time, the Trust may experience timing differences between (i)
the actual receipt of income and actual payment of deductible expenses and (ii)
the inclusion of such income and deduction of such expenses in arriving at REIT
taxable income. Further, it is possible that, from time to time, the Trust may
be allocated a share of net capital gain attributable to the sale of depreciable
property which exceeds its allocable share of cash attributable to that sale. In
such cases, the Trust may have less cash available for distribution than is
necessary to meet the annual 95% distribution requirement or to avoid tax with
respect to the capital gain or the excise tax imposed on certain undistributed
income. To meet the 95% distribution requirement necessary to qualify as a real
estate investment trust or to avoid tax with respect to capital gain or the
excise tax imposed on certain undistributed income, the Trust may find it
appropriate to arrange for short-term (or possibly long-term) borrowings or to
pay distributions in the form of taxable stock dividends. Any such borrowings
for the purpose of making distributions to shareholders of the Trust are
required to be arranged through the Operating Partnership.


                                       17
<PAGE>   21
      Under certain circumstances, the Trust may be able to rectify a failure to
meet the distribution requirement for a year by paying "deficiency dividends" to
shareholders in a later year, which may be included in the Trust's deduction for
dividends paid for the earlier year. Thus, the Trust may be able to avoid being
taxed on amounts distributed as deficiency dividends; however, the Trust will be
required to pay interest based upon the amount of any deduction taken for
deficiency dividends.

FAILURE TO QUALIFY

      If the Trust fails to qualify for taxation as a REIT in any taxable year
and the relief provisions do not apply, the Trust would be subject to tax
(including any applicable alternative minimum tax) on its taxable income at
regular corporate rates. Distributions to shareholders of the Trust in any year
in which the Trust failed to qualify would not be deductible by the Trust nor
would there be a requirement to make distributions. In such event, to the extent
of current and accumulated earnings and profits, all distributions to
shareholders of the Trust would be taxable as ordinary income, and, subject to
certain limitations of the Code, corporate distributees may be eligible for the
dividends received deduction. Unless entitled to relief under specific statutory
provisions, the Trust would also be disqualified from taxation as a REIT for the
four taxable years following the year in which qualification was lost. It is not
possible to state whether in all circumstances the Trust would be entitled to
such statutory relief.

OTHER TAX CONSIDERATIONS

      The Trust may be subject to state or local taxation in various state or
local jurisdictions, including those in which it transacts business. The state
and local tax treatment of the Trust may not conform to the federal income tax
consequences discussed above. Consequently, prospective investors should consult
their own tax advisors regarding the effect of state and local tax laws on an
investment in the Trust.

      To the extent that the Trust engages in real estate development activities
in foreign countries or invests in real estate located in foreign countries, the
Trust's profits from such activities or investments will generally be subject to
tax in the countries where such activities are conducted or such properties are
located. The precise nature and amount of such taxation will depend on the laws
of the countries where the activities are conducted or the properties are
located. Although the Trust will attempt to minimize the amount of such foreign
taxation, there can be no assurance as to whether or the extent to which
measures taken to minimize such taxes will be successful. If the Trust satisfies
the annual distribution requirements for qualification as a REIT and is,
therefore, not subject to federal corporate income tax on that portion of its
ordinary income and capital gain that is currently distributed to its
shareholders, the Trust will generally not be able to recover the cost of any
foreign tax imposed on such profits from its foreign activities or investments
by claiming foreign tax credits against its federal income tax liability on such
profits. Moreover, the Trust will not be able to pass foreign tax credits
through to its shareholders. As a result, to the extent that the Trust is
required to pay taxes in foreign countries, the cash available for distribution
to its shareholders will be reduced accordingly.


                                       18
<PAGE>   22
      The Operating Partnership will receive fees from an affiliated entity as
consideration for services that the Operating Partnership will provide to such
entity in connection with the development and management of the Kings Hill
project in the United Kingdom ("U.K."). The amount of this fee income will not
be qualifying income for purposes of the 75% or 95% gross income tests, although
the Trust does not expect that the revenue derived from such services would
cause it to fail the 75% or 95% gross income tests. The Trust may be subject to
Corporation Tax in the U.K. at the rate of 33% on its share of such fee income
if the Trust is deemed to have a branch or agency in the U.K. as a result of
services that may be performed for such entity in the U.K. In addition, rental
income received by the Trust with respect to leases of real property in the U.K.
would be subject to U.K. withholding tax at the rate of 25%. It is possible that
such rental income (together with any gain arising from the sale or other
disposition of such properties) could instead be subject to Corporation Tax in
the U.K. at the rate of 33% if the U.K. Inland Revenue did not regard the Trust
as holding the properties for purposes of long term investment or if such income
or gain were deemed attributable to a branch or agency of the Trust in the U.K.
Such U.K. taxes will reduce the amount of cash available for distribution by the
Trust to its shareholders out of such income.

TAX ASPECTS OF THE TRUST'S INVESTMENTS IN PARTNERSHIPS

      The following discussion summarizes certain federal income tax
considerations applicable solely to the Trust's investment in the Operating
Partnership and the Property Partnerships (collectively, the "Partnerships").

CLASSIFICATION AS A PARTNERSHIP

      The Trust will be required to include in its income its distributive share
of the Operating Partnership's income and to deduct its distributive share of
the Operating Partnership's losses, and the Trust and the Operating Partnership
will be required to include in computing their income their respective
distributive shares of the income and losses of the Property Partnerships only
if the Operating Partnership and each of the Property Partnerships is
classified, for federal income tax purposes, as a partnership rather than as an
association taxable as a corporation.

      For taxable periods prior to January 1, 1997, an organization formed as a
partnership was treated as a partnership rather than as a corporation for
federal income tax purposes only if it possessed no more than two of the four
corporate characteristics that the Treasury Regulations used to distinguish a
partnership from a corporation. These four characteristics were continuity of
life, centralization of management, limited liability, and free transferability
of interests. Although neither the Operating Partnership nor the Property
Partnerships requested a ruling from the IRS that they would be classified as
partnerships for Federal income tax purposes, rather than as associations
taxable as corporations, Wolf, Block, Schorr and Solis-Cohen LLP had opined
that, based on the provisions of the respective partnership agreements of the
Operating Partnership and each Property Partnership, and certain factual
assumptions and representations as to each of them, the Operating Partnership
and each Property Partnership will be treated as partnerships for federal income
tax purposes and not as associations taxable as corporations. Effective January
1, 1997, newly promulgated Treasury Regulations eliminated the four-factor test
described above and, instead, permit partnerships and other non-corporate
entities to be taxed as partnerships for federal income tax purposes without
regard to the number of corporate characteristics possessed by such entity.


                                       19
<PAGE>   23
Under those Regulations, both the Operating Partnership and each of the Property
Partnerships will be classified as partnerships for federal income tax purposes
unless an affirmative election is made by the entity to be taxed as a
corporation. The Trust has represented that no such election has been made, or
is anticipated to be made, on behalf of the Operating Partnership or any of the
Property Partnerships. Under a special transitional rule in the Regulations, the
IRS will not challenge the classification of an existing entity such as the
Operating Partnership or a Property Partnership for periods prior to January 1,
1997 if: (i) the entity has a "reasonable basis" for its classification; (ii)
the entity and each of its members recognized the federal income tax
consequences of any change in classification of the entity made within the 60
months prior to January 1, 1997; and (iii) neither the entity nor any of its
members had been notified in writing on or before May 8, 1996 that its
classification was under examination by the IRS. Neither the Partnership nor any
of the Property Partnerships changed their classification within the 60 month
period preceding May 8, 1996, nor was any one of them notified that their
classification as a partnership for federal income tax purposes was under
examination by the IRS. Therefore, in reliance on the opinion previously
rendered by Wolf, Block, Schorr and Solis-Cohen LLP, the Operating Partnership
and each of the Property Partnerships should continue to be taxed as
partnerships for federal tax purposes.

      If for any reason the Operating Partnership or a Property Partnership were
taxable as a corporation rather than as a partnership for federal income tax
purposes, the Trust would not be able to satisfy the income and asset
requirements for status as a REIT. In addition, any change in the Operating
Partnership's status or that of a Property Partnership for tax purposes might be
treated as a taxable event, in which case the Trust might incur a tax liability
without any related cash distribution. See "--Taxation of the Trust," above.
Further, items of income and deduction for the Operating Partnership or a
Property Partnership would not pass through to the respective partners, and the
partners would be treated as stockholders for tax purposes. Each Partnership
would be required to pay income tax at regular corporate tax rates on its net
income and distributions to partners would constitute dividends that would not
be deductible in computing the Partnership's taxable income.

INCOME TAXATION OF THE PARTNERSHIPS

      Partners, Not the Operating Partnership or Property Partnerships, Subject
to Tax

      A partnership is not a taxable entity for federal income tax purposes.
Rather, the Trust will be required to take into account its allocable share of
the income, gains, losses, deductions and credits of each of the Operating
Partnership and the Property Partnerships for any taxable year of such
Partnerships ending within or with the taxable year of the Trust, without regard
to whether the Trust has received or will receive any cash distributions. The
same will be true for the Operating Partnership with respect to its allocable
share of the income, gains, losses, deductions and credits of each of the
Property Partnerships.

      Partnership Allocations

      Although a partnership agreement generally will determine the allocation
of income and losses among partners, the allocations provided in the partnership
agreement will be disregarded for tax purposes if they do not comply with the
provisions of Section 704(b) of the Code and the Treasury Regulations
promulgated thereunder.


                                       20
<PAGE>   24
      If an allocation is not recognized for federal income tax purposes, the
item subject to the allocation will be reallocated in accordance with the
partners' interests in the partnership, which will be determined by taking into
account all of the facts and circumstances relating to the economic arrangement
of the partners with respect to such item. The allocations of taxable income and
loss of each of the Operating Partnership and the Property Partnerships are
intended to comply with the requirements of Section 704(b) of the Code and the
Treasury Regulations promulgated thereunder.

      Tax Allocations With Respect to Pre-Contribution Gain

      Pursuant to Section 704(c) of the Code, income, gain, loss, and deduction
attributable to appreciated property that is contributed to a partnership in
exchange for an interest in the partnership must be allocated for federal income
tax purposes in a manner such that the contributor is charged with the
unrealized gain associated with the property at the time of the contribution.
The amount of such unrealized gain is generally equal to the difference between
the fair market value of the contributed property at the time of contribution
and the adjusted tax basis of such property at the time of contribution (the
"Book-Tax Difference"). In general, the fair market value of the properties
owned (directly or indirectly) by the Trust and interests in Property
Partnerships contributed to the Operating Partnership has been substantially in
excess of their respective adjusted tax bases. The partnership agreements of
each of the Operating Partnership and the Property Partnerships require that
allocations attributable to each item of contributed property be made so as to
allocate the tax depreciation available with respect to such property first to
the partners other than the partner that contributed the property, to the extent
of, and in proportion to, their book depreciation, and then, if any tax
depreciation remains, to the partner that contributed the property. Upon the
disposition of any item of contributed property, any gain attributable to the
"built-in" gain of the property at the time of contribution would be allocated
for tax purposes to the contributing partner. These allocations are intended to
be consistent with the Treasury Regulations under Section 704(c) of the Code.

      In general, participants in the formation of the Trust (and the
Partnerships) have been allocated disproportionately lower amounts of
depreciation deductions for tax purposes relative to their percentage interests
in the Operating Partnership, and disproportionately greater shares relative to
their percentage interests in the Operating Partnership of the gain on the sale
by the Partnerships of one or more of the contributed properties. These tax
allocations will tend to reduce or eliminate the Book-Tax Difference over the
life of the Partnerships. Because the partnership agreements of the Partnerships
adopt the "traditional method" in obtaining items allocable under Section 704(c)
of the Code, the amounts of the special allocations of depreciation and gain
under the special allocation rules of Section 704(c) of the Code may be limited
by the so-called "ceiling rule" and may not always eliminate the Book-Tax
Difference on an annual basis or with respect to a specific transaction such as
a sale. Thus, the carryover basis of the contributed assets in the hands of the
Partnerships may cause the Trust to be allocated less depreciation than would be
available for newly purchased properties.

      The foregoing principles also apply in determining the earnings and
profits of the Trust. The application of these rules may result in a larger
share of the distributions from the Trust being taxable to shareholders as
dividends.


                                       21
<PAGE>   25
      Basis in Operating Partnership Interest

      The Trust's adjusted tax basis in its partnership interest in the
Operating Partnership generally (i) will be equal to the amount of cash and the
basis of any other property contributed to the Operating Partnership by the
Trust plus the fair market value of the Shares it issues or cash it pays upon
conversion of interests in the Operating Partnership, (ii) has been, and will
be, increased by (a) its allocable share of the Operating Partnership's income
and (b) its allocable share of indebtedness of the Operating Partnership and of
the Property Partnerships and (iii) has been, and will be, reduced (but not
below zero) by the Trust's allocable share of (a) the Operating Partnership's
loss and (b) the amount of cash distributed to the Trust, and by constructive
distributions resulting from a reduction in the Trust's share of indebtedness of
the Operating Partnership and the Property Partnerships.

      If the allocation of the Trust's distributive share of the Operating
Partnership's loss would reduce the adjusted tax basis of the Trust's
partnership interest in the Operating Partnership below zero, the loss is
deferred until such time as the recognition of such loss would not reduce the
Trust's adjusted tax basis below zero. To the extent that the Operating
Partnership's distributions, or any decrease in the Trust's share of the
indebtedness of the Operating Partnership or a Property Partnership (each such
decrease being considered a constructive cash distribution to the partners),
would reduce the Trust's adjusted tax basis below zero, such distributions
(including such constructive distributions) would be includible as taxable
income to the Trust in the amount of such excess. Such distributions and
constructive distributions would normally be characterized as capital gain, and
if the Trust's partnership interest in the Operating Partnership has been held
for longer than the long-term capital gain holding period (currently, one year),
the distributions and constructive distributions would constitute long-term
capital gain. Based on Treasury Regulations to be issued, the tax rates
applicable to such capital gain will likely vary depending on the precise amount
of time such interest has been held by the Trust and the nature of the Operating
Partnership's property. Based on certain undertakings by limited partners of the
Operating Partnership, the Exchangeable Subordinated Debentures issued by the
Operating Partnership are allocated for purposes of Section 752 of the Code
disproportionately in favor of certain limited partners.

SALE OF THE PARTNERSHIPS' PROPERTY

      Generally, any gain realized by the Operating Partnership or a Property
Partnership on the sale of property held by the Operating Partnership or a
Property Partnership, or on the sale of partnership interests in the Property
Partnerships, if the property or partnership interests are held for more than
one year, will be long-term capital gain (except for any portion of such gain
that is treated as depreciation or cost recovery recapture), and may result in
capital gain distributions to the shareholders. See "--Taxation of Taxable
Domestic Shareholders," below.

      The Trust's share of any gain realized on the sale of any property held by
the Operating Partnership or a Property Partnership as inventory or other
property held primarily for sale to customers in the ordinary course of the
trade or business of any of the Operating Partnership or the Property
Partnerships will, however, be treated as income from a prohibited transaction
that is subject to a 100% penalty tax. Under existing law, whether property is
held as inventory or primarily for sale to customers in the ordinary course of a
trade or business is a question of fact that depends on all the facts and
circumstances with respect to the particular transaction. The Operating


                                       22
<PAGE>   26
Partnership and the Property Partnerships intend to hold their properties for
investment with a view to long-term appreciation, to engage in the business of
acquiring, developing, owning and operating their properties and to make such
occasional sales of such properties, including peripheral land, as are
consistent with the investment objectives of the Trust and the Operating
Partnership. Complete assurance cannot be given, however, that the Trust will be
able to avoid owning property that may be characterized as property held
"primarily for sale to customers in the ordinary course of business."

TAXATION OF TAXABLE DOMESTIC SHAREHOLDERS

      As long as the Trust qualifies as a REIT, distributions made to the
Trust's taxable U.S. shareholders out of current or accumulated earnings and
profits (and not designated as capital gain dividends) will be taken into
account by such U.S. shareholders as ordinary income and will not be eligible
for the dividends received deduction for corporations. Distributions that are
designated as capital gain dividends will be taxed as gain from the sale or
exchange of a capital asset held for more than one year (to the extent they do
not exceed the Trust's actual net capital gain for the taxable year) without
regard to the period for which the shareholder has held its stock. Subject to
certain limitations, the Trust may further designate capital gain dividends as a
"20% rate gain distribution," an "unrecaptured section 1250 gain distribution,"
or a "28% rate gain distribution," in which case such dividends will be taxable
to recipient individual shareholders when received at tax rates of 20%, 25% and
28%, respectively. If no additional designation is made regarding a capital gain
distribution, it will be treated as a 28% rate gain distribution. Corporate
shareholders may be required to treat up to 20% of certain capital gain
dividends as ordinary income.

      Distributions in excess of current and accumulated earnings and profits
will not be taxable to a shareholder to the extent that they do not exceed the
adjusted basis of the shareholder's shares, but rather will reduce the adjusted
basis of such shares. To the extent that such distributions exceed the adjusted
basis of a shareholder's shares, they will be included in income as short-term,
mid-term or long-term capital gain (depending on the length of time the shares
have been held) assuming the shares are a capital asset in the hands of the
shareholder. In addition, any dividend declared by the Trust in October,
November or December of any year payable to a shareholder of record on a
specified date in any such month shall be treated as both paid by the Trust and
received by the shareholder on December 31 of such year, provided that the
dividend is actually paid by the Trust during January of the following calendar
year. Shareholders may not include in their individual income tax returns any
net operating losses or capital losses of the Trust.

      In general, a domestic shareholder will realize capital gain or loss on
the disposition of Common Shares equal to the difference between (i) the amount
of cash and the fair market value of any property received on such disposition,
and (ii) the shareholder's adjusted basis of such Common Shares. Subject to
certain exceptions, the maximum rate of tax on net capital gains of individuals,
trusts and estates from the sale or exchange of capital assets is 28% in respect
of capital assets held for more than one year but not more than 18 months and is
20% in respect of capital assets held for more than 18 months. Any loss upon a
sale or exchange of shares by a shareholder who has held such shares for six
months or less (after applying certain holding-period rules) will be treated as
a long-term capital loss to the extent of distributions from the Trust required
to be treated by such shareholder as long-term capital gain.


                                       23
<PAGE>   27
      Effective for its taxable years beginning on or after January 1, 1998, the
Trust may elect to retain its net long-term capital gains recognized during a
taxable year ("Retained Gains") and pay a corporate-level tax on such Retained
Gains. Corporations are currently subject to a maximum 35 percent tax on
recognized capital gains. A shareholder owning the Trust's shares of beneficial
interest on December 31 of any taxable year in which the Trust has Retained
Gains would be required to include in gross income such shareholder's
proportionate share of the Retained Gains (as designated by the Trust in a
notice mailed to shareholders within 60 days following the end of the taxable
year). The amount of any corporate-level tax paid by the Trust in respect of the
Retained Gains (the "Trust Tax") would be treated as having been paid by the
shareholders of the Trust and each shareholder would receive a credit for such
shareholder's share of the Trust Tax. A shareholder's basis in his shares of
beneficial interest would increase by the excess of such shareholder's
proportionate share of the Retained Gains over the shareholder's share of the
Trust Tax. Unless the Retained Gains were treated as actually distributed, it is
possible that the Retained Gains might be subject to the Excise Tax.

BACKUP WITHHOLDING

      The Trust will report to its U.S. shareholders and the IRS the amount of
distributions paid during each calendar year, and the amount of tax withheld, if
any. Under the backup withholding rules, a shareholder may be subject to backup
withholding at the rate of 31% with respect to distributions paid unless such
shareholder (a) is a corporation or comes within certain other exempt categories
and, when required, demonstrates this fact or (b) provides a taxpayer
identification number, certifies as to no loss of exemption from backup
withholding, and otherwise complies with applicable requirements of the backup
withholding rules. A shareholder that does not provide the Trust with his
correct taxpayer identification number may also be subject to penalties imposed
by the IRS. Any amount paid as backup withholding will be creditable against the
shareholder's income tax liability. In addition, the Trust may be required to
withhold a portion of capital gain distributions to shareholders who fail to
certify their non-foreign status to the Trust. The United States Treasury has
recently issued final regulations (the "Final Regulations") which affect the
procedures regarding the withholding and information reporting rules discussed
above. In general, the Final Regulations do not alter the substantive
withholding and information reporting requirements but unify current
certification procedures and forms and clarify and modify reliance standards.
The Final Regulations are generally effective for payments made on or after
January 1, 1999, subject to certain transition rules. Prospective investors
should consult their own tax advisors concerning the adoption of the Final
Regulations and the potential effect on their ownership of Common Shares. See
"-- Taxation of Foreign Shareholders."

TAXATION OF TAX-EXEMPT SHAREHOLDERS

      Generally, distributions to a tax-exempt entity from a real estate
investment trust do not constitute unrelated business taxable income, as defined
in Section 512(a) of the Code ("UBTI"), provided that the tax-exempt entity has
not financed its acquisition of its shares with "acquisition indebtedness"
within the meaning of the Code and the shares are not otherwise used in an
unrelated trade or business of the tax-exempt entity. Thus, distributions by the
Trust to shareholders that are tax-exempt should not be taxable as UBTI,
provided that no acquisition indebtedness was incurred with respect to such
shares.


                                       24
<PAGE>   28
      Some or all of the distributions by a real estate investment trust to a
tax-exempt employee's pension fund that owns more than 10% in value of the real
estate investment trust are treated as UBTI if the real estate investment trust
constitutes a "pension-held REIT" and if other conditions are met. In order to
constitute a "pension-held REIT" the real estate investment trust must meet the
test for classification as a real estate investment trust only because
tax-exempt pension funds are not treated as a single individual for purposes of
the "five-or-fewer" rule (see "Risk Factors --Limitations on Changes in Control
- -- Ownership Limit") and either (A) one pension fund owns more than 25% in value
of the real estate investment trust or (B) one or more pension funds (holding at
least 10% in value of the real estate investment trust each) own, in the
aggregate, more than 50% of the value of the real estate investment trust. In
addition, the gross income of the real estate investment trust derived from
activities that would constitute unrelated trades or businesses, computed as if
the REIT was a "qualified trust," must be at least five percent of the gross
income of the real estate investment trust in the taxable year in which the
distributions are made. The ownership limitations in the Declaration of Trust
(assuming no waiver by the Board of Trustees) would prevent the Trust from being
classified as a "pension-held REIT."

TAXATION OF FOREIGN SHAREHOLDERS

      The rules governing United States federal income taxation of nonresident
alien individuals, foreign corporations, foreign partnerships and other foreign
shareholders (collectively, "Non-U.S. Shareholders") are complex, and no attempt
will be made herein to provide more than a summary of the rules. Prospective
Non-U.S. Shareholders should consult with their own tax advisors to determine
the impact of federal, state and local income tax laws with regard to an
investment in the Common Shares offered hereby, including any reporting
requirements, as well as the tax treatment of such an investment under their
home country laws. If income from the investment in the Common Shares offered
hereby is treated as "effectively connected" with the Non-U.S. Shareholder's
conduct of a United States trade or business, the Non-U.S. Shareholder generally
will be subject to a tax at graduated rates, in the same manner as U.S.
shareholders are taxed with respect to the dividends (and may also be subject to
the 30% "branch profits" tax in the case of a shareholder that is a foreign
corporation). The remainder of this discussion assumes that the distributions do
not constitute "effectively connected" income. Prospective investors whose
investment in Common Shares may be "effectively connected" with the conduct of a
United States trade or business should consult their own tax advisors as to the
tax consequences thereof.

      Distributions by the Trust that are not attributable to gain from sales or
exchanges by the Trust of United States real property interests and not
designated by the Trust as capital gains dividends will be treated as dividends
of ordinary income to the extent that they are made out of current or
accumulated earnings and profits of the Trust. Such distributions, ordinarily,
will be subject to a withholding tax equal to 30% of the gross amount of the
distribution unless an applicable tax treaty reduces or eliminates that tax.
Distributions in excess of current and accumulated earnings and profits of the
Trust will not be taxable to a shareholder to the extent that such distributions
do not exceed the adjusted basis of the shareholder's shares, but rather will
reduce the adjusted basis of such shares. To the extent that distributions in
excess of current accumulated earnings and profits exceed the adjusted basis of
a Non-U.S. Shareholder's shares, such 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 disposition of his shares in the Trust, as described
below. The Trust expects to withhold United States income tax at the rate of 30%
on the gross amount of any distributions


                                       25
<PAGE>   29
made to a Non-U.S. Shareholder unless (i) a lower treaty rate applies and the
Non-U.S. Shareholder files all necessary forms required to establish eligibility
for the lower rate and provides certification as to such eligibility, if
necessary, or (ii) the Non-U.S. Shareholder files an IRS Form 4224 with the
Trust certifying that the investment to which the distribution relates is
"effectively connected" to a United States trade or business of such Non-U.S.
Shareholder. Lower treaty rates generally applicable to dividend income may not
necessarily apply to distributions from a REIT, such as the Trust. If it cannot
be determined at the time a distribution is made whether or not such
distribution will be in excess of current and accumulated earnings and profits,
the distributions will be subject to withholding at the same rate as dividends.
Pursuant to recently enacted legislation, effective for distributions made after
August 20, 1996, the Trust is obligated to withhold 10% of the amount of any
distribution in excess of the Trust's current and accumulated earnings and
profits. However, amounts withheld are refundable if it is subsequently
determined that the distribution was in excess of current and accumulated
earnings and profits of the Trust and the amount withheld exceeded the Non-U.S.
Shareholders' United States tax liability, if any.

      For any year in which the Trust qualifies as a REIT, distributions that
are attributable to gain from sales or exchanges by the Trust of United States
real property interests will be taxed to a Non-U.S. Shareholder under the
provisions of the Foreign Investment in Real Property Tax Act of 1980
("FIRPTA"). Under FIRPTA, these distributions are taxed to a Non-U.S.
Shareholder as if the gain were "effectively connected" with a United States
business. Non-U.S. Shareholders would be taxed at the normal capital gain rates
applicable to domestic shareholders (subject to applicable alternative minimum
tax and a special alternative minimum tax in the case of nonresident alien
individuals), without regard to whether such distributions are designated by the
Trust as capital gain dividends. Also, distributions subject to FIRPTA may be
subject to a 30% "branch profits" tax in the hands of a foreign corporate
shareholder not entitled to treaty exemption. The Trust is required by
applicable income tax regulations that have been promulgated under the Code (the
"Treasury Regulations") to withhold 35% of any distribution that could be
designated by the Trust as a capital gains dividend. This amount is creditable
against the Non-U.S. Shareholder's FIRPTA tax liability.

      Gain recognized by a Non-U.S. Shareholder upon a sale of shares generally
will not be taxed under FIRPTA if the Trust is a "domestically controlled REIT,"
defined generally as a REIT in which at all times during a specified testing
period less than 50% in value of the stock was held directly or indirectly by
foreign persons. The Trust currently is a "domestically controlled REIT," and
anticipates continuing to be so classified, and therefore the sale of the Common
Shares offered hereby should not be subject to taxation under FIRPTA. However,
because the Common Shares will be publicly traded, no assurance can be given
that the Trust will continue to so qualify. Notwithstanding the foregoing, any
gain not otherwise subject to FIRPTA will be taxable to a Non-U.S. Shareholder
if (i) investment in the shares is effectively connected with the Non-U.S.
Shareholder's United States trade or business, in which case the Non-U.S.
Shareholder will be subject to the same treatment as U.S. shareholders with
respect to the gain (a shareholder that is a foreign corporation may also be
subject to the 30% "branch profits" tax), or (ii) the Non-U.S. Shareholder is a
nonresident alien individual who was present in the United States for 183 days
or more during the taxable year and has a "tax home" in the United States, in
which case the nonresident alien individual will be subject to a 30% tax on the
individual's capital gains. If the gain on the sale of shares were to be subject
to taxation under FIRPTA, the Non-U.S. Shareholder will be subject to the same
treatment as U.S. shareholders with respect to the gain (subject to applicable
alternative minimum tax and a special alternative minimum tax in the case of
nonresident alien


                                       26
<PAGE>   30
individuals and, in the case of foreign corporations, subject to the possible
application of the 30% "branch profits" tax).

      If the proceeds of a disposition of Common Shares are paid by or through a
United States office of a broker, the payment is subject to information
reporting requirements and to backup withholding unless the disposing Non-U.S.
Shareholder certifies as to his name, address, and non-United States status or
otherwise establishes an exemption. Generally, United States information
reporting and backup withholding will not apply to the payment of disposition
proceeds if the payment is made outside the United States through a non-United
States broker. United States information reporting (but not backup withholding)
will apply, however, to a payment of disposition proceeds outside the United
States if (i) the payment is made through an office outside the United States
that is either (a) a United States person, (b) a foreign person that derives 50%
or more of its gross income for certain periods from the conduct of a trade or
business in the United States or (c) a "controlled foreign corporation" for
United States federal income tax purposes, and (ii) the broker fails to obtain
documentary evidence that the Shareholder is a Non-U.S. Shareholder and that
certain conditions are met or that the Non-U.S. Shareholder is otherwise
entitled to an exemption. The Final Regulations, issued by the United States
Treasury on October 6, 1997, affect the rules applicable to payments to foreign
persons. In general, the Final Regulations do not alter the substantive
withholding and information reporting requirements but unify current
certification procedures and forms and clarify and modify reliance standards.
The Final Regulations also address certain issues relating to intermediary
certification procedures designed to simplify compliance by withholding agents.
The Final Regulations are generally effective for payments made on or after
January 1, 1999, subject to certain transition rules. Prospective investors
should consult their own tax advisors concerning the adoption of the Final
Regulations and the potential effect on their ownership of the Common Shares.

                              PLAN OF DISTRIBUTION

      The Company has been advised by the Selling Shareholder that the Selling
Shareholder may sell the Shares from time to time in transactions on the NYSE,
in negotiated transactions, or otherwise, or by a combination of these methods,
at fixed prices which may be changed, at market prices at the time of sale, at
prices related to market prices or at negotiated prices. The Selling Shareholder
may effect these transactions by selling the Shares to or through
broker-dealers, who may receive compensation in the form of discounts,
concessions or commissions from the Selling Shareholder or the purchasers of the
Shares for whom the broker-dealer may act as an agent or to whom they may sell
the Shares as a principal, or both. The compensation to a particular
broker-dealer may be in excess of customary commissions.

      The Selling Shareholder and broker-dealers who act in connection with the
sale of the Shares may be deemed to be "underwriters" within the meaning of the
Securities Act, and any commissions received by such broker-dealers and profits
on any resale of the Shares as a principal may be deemed to be underwriting
discounts and commissions under the Securities Act.

      Any broker-dealer participating in such transactions as agent may receive
commissions from the Selling Shareholder (and, if they act as agent for the
purchaser of such Shares, from such purchaser). Broker-dealers may agree with
the Selling Shareholder to sell a specified number of Shares at a stipulated
price per share, and, to the extent such a broker-dealer is unable to do so
acting


                                       27
<PAGE>   31
as agent for the Selling Shareholder, to purchase as principal any unsold Shares
at the price required to fulfill the broker-dealer commitment to the Selling
Shareholder. Broker-dealers who acquire Shares as principal may thereafter
resell such Shares from time to time in transactions (which may involve crosses
and block transactions and which may involve sales to and through other
broker-dealers, including transactions of the nature described above) in the
over-the-counter market, in negotiated transactions or otherwise at market
prices prevailing at the time of sale or at negotiated prices, and in connection
with such resales may pay to or receive from the purchasers of such Shares
commissions computed as described above. To the extent required under the
Securities Act, a supplemental prospectus will be filed, disclosing (a) the name
of any such broker-dealers; (b) the number of Shares involved; (c) the price at
which such Shares are to be sold; (d) the commissions paid or discounts or
concessions allowed to such broker-dealers, where applicable; (e) that such
broker-dealers did not conduct any investigation to verify the information set
out or incorporated by reference in this Prospectus, as supplemented; and (f)
other facts material to the transaction.

      Under applicable rules and regulations under the Exchange Act, any person
engaged in a distribution of the Shares may not simultaneously engage in market
making activities with respect to such securities for a period beginning when
such person becomes a distribution participant and ending upon such person's
completion of participation in a distribution, including stabilization
activities in the Common Shares to effect syndicate covering transactions, to
impose penalty bids or to effect passive market making bids. In addition and
without limiting the foregoing, in connection with transactions in the Shares,
the Selling Shareholder will be subject to applicable provisions of the Exchange
Act and the rules and regulations thereunder, including, without limitation,
Rule 10b-5 and, insofar as the Selling Shareholder is a distribution
participant, Regulation M and Rules 100, 101, 102, 103, 104 and 105 thereof. All
of the foregoing may affect the marketability of the Shares.

      The Selling Shareholder will pay all commissions and certain other
expenses associated with the sale of the Shares. The Shares offered hereby are
being registered pursuant to contractual obligations of the Company, and the
Company has paid the expenses of the preparation of this Prospectus. The Company
has also agreed to indemnify the Selling Shareholder with respect to the Shares
offered hereby against certain liabilities, including, without limitation,
certain liabilities under the Securities Act, or, if such indemnity is
unavailable, to contribute toward amounts required to be paid in respect of such
liabilities.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.


      Under Section 8-301(15) and 2-418 of the Maryland General Corporation Law,
as amended, the Trust has the power to indemnify trustees and officers under
certain prescribed circumstances (including when authorized by a majority vote
of a quorum of disinterested trustees, by a majority vote of a committee of two
or more disinterested trustees, by independent legal counsel, or by
shareholders) and, subject to certain limitations (including, unless otherwise
determined by the proper court, when such trustee or officer is adjudged liable
to the Trust), against certain costs and expenses, including attorneys' fees
actually and reasonably incurred in connection with any action, suit or
proceeding, whether civil, criminal, administrative or investigative, to which
any of them is a party by reason of his or her being a trustee or officer of the
Trust if it is determined that he or she acted in accordance with the applicable
standard of conduct set forth in such statutory provisions including when such
trustee or officer acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the Trust's best interests, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
his or her conduct was unlawful.

      Article XII of the Trust's By-laws provides that the Trust has the power
to indemnify trustees, officers and shareholders of the Trust against expenses
(including legal fees) reasonably incurred by any of them in connection with the
successful defense of a proceeding to which such person was made a party by
reason of such status, whether the success of such defense was on the merits or
otherwise, to the maximum extent permitted by law. The trustees, officers and
shareholders of the Trust also have the right, in certain circumstances, to be
paid in advance for expenses incurred in connection with any such proceedings.

            (1) To file, during any period in which offers or sales are being
      made, a post-effective amendment to this Registration Statement:

                  (i) To include any prospectus required by Section 10(a)(3) of
            the Securities Act;

                  (ii) To reflect in the Prospectus any facts or events arising
            after the effective date of the Registration Statement (or the most
            recent post-effective amendment thereof) which, individually or in
            the aggregate, represent a fundamental change in the information set
            forth in the Registration Statement. Notwithstanding the foregoing,
            any increase or decrease in volume of securities offered (if the
            total dollar value of securities offered would not exceed that which
            was registered) and any deviation from the low or high end of the
            estimated maximum offering range may be reflected in the form of
            prospectus filed with the Commission pursuant to Rule 424(b) if, in
            the aggregate, the changes in volume and price represent no more
            than a 20 percent change in the maximum aggregate offering price set
            forth in the "Calculation of Registration Fee" table in the
            effective Registration Statement;

                  (iii) To include any material information with respect to the
            plan of distribution not previously disclosed in the Registration
            Statement or any material change to such information in the
            Registration Statement;

      provided, however, that paragraphs (i) and (ii) of this paragraph do not
      apply if the information required to be included in a post-effective
      amendment by those paragraphs is contained in periodic reports filed with
      or furnished to the Commission by the Registrant pursuant to Section 13 or
      Section 15(d) of the Exchange Act that are incorporated by reference in
      the Registration Statement.

            (2) That, for the purpose of determining any liability under the
      Securities Act, each such post-effective amendment shall be deemed to be a
      new registration statement relating to the securities offered therein, and
      the offering of such securities at that time shall be deemed to be the
      initial bona fide offering thereof.

            (3) To remove from registration by means of a post-effective
      amendment any of the securities being registered which remain unsold at
      the termination of the offering.

      (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

      (c) Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to trustees, officers or controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the


                                      II-3
<PAGE>   39
payment by the Registrant of expenses incurred or paid by a trustee, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such trustee, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.


                                      II-4

      Pursuant to the requirements of the Securities Act of 1933, as amended,
the undersigned Registrant certifies that it has reasonable grounds to believe
that it meets all of the requirements for filing on Form S-3 and has duly caused
this Registration Statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Malvern, Commonwealth of Pennsylvania,
on the 8th day of September, 1998.

                  Re:   Liberty Property Trust
                        Registration Statement on Form S-3

Ladies and Gentlemen:

                  We have acted as Maryland counsel for Liberty Property Trust,
a Maryland real estate investment trust (the "Company"), in connection with
certain matters of Maryland law arising out of the registration of up to
144,328 common shares of beneficial interest of the Company, $0.001 par value
(the "Shares"), proposed to be offered for resale from time to time, together
or separately, at prices and on terms to be determined at the time of offering
pursuant to a registration statement on Form S-3 (the "S-3 Registration
Statement") and the prospectus contained in the S-3 Registration Statement (the
"S-3 Prospectus").                                                  

                  In connection with our representation of the Company and as a
basis for the opinions hereinafter set forth, we have examined originals or
photostatic copies of the following documents (hereinafter collectively referred
to as the "Documents"):

                  a. The S-3 Registration Statement, in the form filed by the
                  Company with the Securities and Exchange Commission (the
                  "Commission") under the Securities Act of 1933 (the "Act");
<PAGE>   2
                  b. The S-3 Prospectus;

                  c. The Amended and Restated Declaration of Trust of the
                  Company recorded on May 29, 1997 (the "Declaration of Trust");

                  d. Articles Supplementary of the Company recorded on August 7,
                  1997 and Articles Supplementary of the Company recorded on
                  December 23, 1997 (the "Articles Supplementary");

                  e. The Bylaws of the Company;

                  f. Resolutions adopted by the Board of Trustees of the Company
                  dated June 24, 1998; and

                  g. Such other documents and matters as we have deemed
                  necessary and appropriate to express the opinions set forth in
                  this letter, subject to the limitations, assumptions and
                  qualifications noted below.

                  In expressing the opinion set forth below, we have assumed,
and so far as is known to us there are no facts inconsistent with, the
following:

                  1. Each of the parties (other than the Company) executing any
of the Documents has duly and validly executed and delivered each of the
Documents to which such party is a signatory, and such party's obligations set
forth therein are legal, valid and binding and are enforceable in accordance
with all stated terms except as limited (a) by bankruptcy, insolvency,
reorganization, moratorium, fraudulent conveyance or other laws relating to or
affecting the enforcement of creditors' rights or (b) by general equitable
principles;

                  2. Each individual executing any of the Documents on behalf of
a party is duly authorized and legally competent to do so;

                  3. All Documents submitted to us as originals are authentic.
All Documents submitted to us as certified or photostatic copies conformed to
the original documents. All signatures on all such documents are genuine. All
public records reviewed or relied upon by us or on our behalf are true and
complete. All statements and information contained in the Documents are true and
complete;

                  4. There will be no changes in applicable law between the date
of this opinion and any date of issuance or delivery of the Shares;

                  5. At the time of delivery of the Shares, all contemplated
additional actions shall have been taken and the authorization of the issuance
of the Shares will not have been modified or rescinded;
<PAGE>   3
                  6. The issuance, execution and delivery of the Shares, and the
compliance by the Company with the terms of the Shares, will not violate any
then-applicable law or result in a default under, breach of, or violation of any
provision of any instrument or agreement then binding on the Company, or any
restriction imposed by any court or governmental body having jurisdiction over
the Company;

                  7. The consideration received or proposed to be received for
the issuance and sale of the Shares as contemplated by each of the S-3
Registration Statement and the S-3 Prospectus is not less than the par value per
share; and

                  8. The aggregate number of shares of the Company which would
be outstanding after the issuance of any of the Shares and any other
contemporaneously issued or reserved common shares or preferred shares, together
with the number of common shares and preferred shares previously issued and
outstanding and the number of common shares and preferred shares previously
reserved for issuance upon the conversion or exchange of other securities issued
by the Company or Liberty Property Limited Partnership, a Pennsylvania limited
partnership of whom the Company is the sole general partner, does not exceed the
number of then-authorized shares of the Company.

                  On the basis of the foregoing, and subject to the
qualifications and limitations stated herein, it is our opinion that:

                  When and if (a) the definitive terms of any offering of the
Shares have been duly established, in accordance with resolutions of the Board
of Trustees authorizing the issuance and sale of the Shares, and (b) those
Shares so offered have been duly issued and delivered in the manner and for the
consideration contemplated by each of the S-3 Registration Statement and the S-3
Prospectus, those Shares will be validly issued, fully paid and nonassessable.

                  The foregoing opinion is limited to the laws of the State of
Maryland and we do not express any opinion herein concerning any other law. We
assume no obligation to supplement this opinion if any applicable law changes
after the date hereof or if we become aware of any facts that might change the
opinions expressed herein after the date hereof.

                  We hereby consent to the filing of this opinion as an exhibit
to the S-3 Registration Statement and to the use of the name of our firm
therein. In giving this consent, we do not admit that we are within the category
of persons whose consent is required by Section 7 of the Securities Act of 1933.

                                       Very truly yours,

                                       WEINBERG & GREEN LLC
