                                  THE COMPANY
 
  Liberty Property Trust is one of the largest owners and operators of
suburban industrial and office real estate in the United States. The Trust is
a self-administered and self-managed Maryland real estate investment trust
("REIT") that was formed to continue and expand the commercial real estate
business of Rouse & Associates, a developer and manager of commercial real
estate in the Mid-Atlantic and Southeastern states, founded in 1972. The Trust
provides leasing, property management, acquisition, development, construction
and design management and other related services to a portfolio which, as of
September 30, 1996, consisted of 242 industrial and office properties.
 
  On a consolidated basis, substantially all of the Trust's assets are owned
directly or indirectly by, and all of the Trust's operations are conducted
directly or indirectly by, Liberty Property Limited Partnership, a
Pennsylvania limited partnership. As used herein, unless the context otherwise
requires, such partnership, together with its direct and indirect
subsidiaries, is referred to as the "Operating Partnership" and the Operating
Partnership, together with the Trust (and, where the context requires, the
predecessor entity), is referred to as the "Company." The Trust is the sole
general partner and also is a limited partner of the Operating Partnership,
with a combined equity interest in the Operating Partnership of 89.87% at
September 30, 1996.
 
  The Company's primary goals are to increase funds from operations and,
ultimately, cash available for distribution to shareholders. See "Selected
Financial Data" in the Prospectus Supplement for the definitions of these
terms. The strategy for achieving these goals is to increase the profitability
of the Company's portfolio by delivering outstanding tenant service,
emphasizing marketing to attract new tenants and enhancing the portfolio
through opportunistic and strategic acquisitions, as well as developing high
quality projects, in markets with solid growth opportunities. In pursuing this
strategy, the Company seeks to manage its capital structure to fund growth
while maintaining the strength of its balance sheet.
 
  The Company owned 242 properties as of September 30, 1996, including 163
industrial and 79 office properties, which at that date were approximately
93.1% leased to over 700 tenants. In addition to the 242 properties, the
Company had 22 buildings under construction as of September 30, 1996. The
Company also owns four properties located in the United Kingdom, three of
which are under construction.
 
  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 primary markets.
 
                                USE OF PROCEEDS
 
  Unless otherwise provided in the Prospectus Supplement, the net proceeds, if
any, from the sale of the Securities offered hereby will be used for general
business purposes, including the acquisition of properties or
 
                                       4
<PAGE>
 
other assets. At the date hereof, no specific material proposed purchases have
been identified as probable. The amount of Securities offered from time to
time pursuant to this Prospectus and any Prospectus Supplement, and the
precise amounts and timing of the application of net proceeds from the sale of
such Securities, will depend upon funding requirements of the Company. If the
Company elects at the time of an issuance of Securities to make different or
more specific use of proceeds than set forth herein, such use will be
described in the Prospectus Supplement.
 
                      RATIOS OF EARNINGS TO FIXED CHARGES
 
  The ratios of earnings to fixed charges (i) of the Trust for the nine month
periods ended September 30, 1996 and September 30, 1995, for the year ended
December 31, 1995 and for the period from June 23, 1994 to December 31, 1994
were 1.85, 1.65, 1.65 and 2.04, respectively. The ratio of earnings to fixed
charges were computed by dividing earnings by fixed charges. For this purpose,
earnings have been calculated by adding fixed charges (excluding capitalized
interest) to income (loss) before minority interest and extraordinary items.
Fixed charges consist of interest costs, whether expensed or capitalized, and
amortization of deferred financing costs.
 
  Prior to the completion of the initial public offering of its Common Shares
on June 23, 1994, the operations of the Trust were conducted through its
predecessor, Rouse & Associates and certain of its affiliates (collectively,
the "Rouse Group"). In connection with completion of the initial public
offering, the Company reorganized the Rouse Group and substantially
deleveraged the predecessor's asset base. As a result of these factors, the
Company does not consider information relating to the ratio of earnings to
fixed charges for the periods prior to the completion of the public offering
to be meaningful.
 
                        DESCRIPTION OF DEBT SECURITIES
 
  The Trust Debt Securities and Partnership Debt Securities (together, "Debt
Securities") may each be issued in one or more series under a senior indenture
(the "Senior Indenture") or a subordinated indenture (the "Subordinated
Indenture" and, together with the Senior Indenture, the "Indenture"), in each
case between the Trust or the Operating Partnership and a Trustee (a
"Trustee"), which may be the same Trustee, and in the forms that have been
filed as exhibits to the Registration Statement, subject to the terms of such
amendments or supplements thereto as may be entered into from time to time and
filed with the Commission as exhibits to or incorporated by reference in the
Registration Statement. The following summaries of certain provisions of the
Indentures do not purport to be complete and are subject to, and qualified in
their entirety by reference to, all provisions of the Indentures, including
the definitions therein of certain terms. Wherever particular sections or
defined terms of the Indentures are summarized herein or in a Prospectus
Supplement, it is intended that such sections or defined terms (including,
unless otherwise indicated herein, definitions of terms capitalized in such
summaries) shall be incorporated herein or therein by reference. The following
sets forth certain general terms and provisions of the Debt Securities to
which any Prospectus Supplement may relate. The particular terms of the Debt
Securities offered by any Prospectus Supplement and the extent, if any, to
which such general provisions may apply to the Debt Securities so offered,
will be described in the Prospectus Supplement relating to such Debt
Securities. The Trust and the Operating Partnership are each referred to as an
"Issuer" for purposes of the following summary.
 
  The Issuer's rights and the rights of its creditors, including the holders
of the Debt Securities offered hereby, to participate in the assets of any
subsidiary upon the latter's liquidation or recapitalization will be subject
to the prior claims of the subsidiary's creditors except, subject to certain
limitations, to the extent that the Issuer may itself be a creditor with
recognized claims against the subsidiary.

issued under the Senior Indenture will rank on a parity with all other

forth in the Subordinated Indenture. See "Special Terms Relating to
Subordinated Debt Securities."

  Debt Securities may be issued as Original Issue Discount Securities to be
sold at a discount below their principal amount, which discount may be
substantial. In the event of an acceleration of the maturity of any Original
Issue Discount Security, the amount payable to the holder of such Original
Issue Discount Security upon such acceleration will be determined in
accordance with the applicable Prospectus Supplement, the terms of such Debt
Security and the applicable Indenture, but will be an amount less than the
amount payable at the maturity of such Original Issue Discount Security. All
material federal income tax, accounting and other considerations applicable
thereto will be described in the Prospectus Supplement relating thereto.
 
  Debt Securities may also be issued under the Indentures upon exercise of
Debt Warrants. See "Description of Warrants."
 
REGISTRATION, TRANSFER, PAYMENT AND PAYING AGENT
 
  Unless otherwise indicated in the applicable Prospectus Supplement, each
series of Debt Securities will be issued in registered form only, without
coupons. The Indentures, however, provide that the Issuer may also issue Debt
Securities in bearer form only, or in both registered and bearer form. Debt
Securities issued in bearer form shall have interest coupons attached, unless
issued as Original Issue Discount Securities. Debt Securities in bearer form
shall not be offered, sold, resold or delivered in connection with their
original issuance in the United States or to any United States person (as
defined below) other than through offices located outside the United States of
certain United States financial institutions. As used herein, "United States
person" means any citizen or resident of the United States, any corporation,
partnership or other entity created or organized in or under the laws of the
United States, or any estate or trust, the income of which is subject to
United States federal income taxation regardless of its source, and "United

District of Columbia), its territories, its possessions and other areas
subject to its jurisdiction. Purchasers of Debt Securities in bearer form will
be subject to certification procedures and may be affected by certain
limitations under United States tax laws. Such procedures and limitations will
be described in the Prospectus Supplement relating to the offering of the Debt
Securities in bearer form.
 
  Unless otherwise indicated in the applicable Prospectus Supplement, Debt
Securities will be issued in denominations of $1,000 or any integral multiple
thereof. No service charge will be made for any transfer, exchange or
conversion of the Debt Securities but the Issuer may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.
 
  Unless otherwise described in the Prospectus Supplement relating thereto,
the principal, premium, if any, and interest, if any, of or on the Debt
Securities will be payable, transfer of the Debt Securities will be
 
                                       7
<PAGE>
 
registerable, and, if applicable, any Convertible Debt Securities (as
hereinafter defined) will be convertible, at the office or agency of the
Issuer maintained for that purpose, as the Issuer may designate from time to
time, provided that payments of interest may be made at the option of the
Issuer by check mailed to the address appearing in the Security Register of
the person in whose name such registered Debt Security is registered at the
close of business on the applicable Regular Record Date(s).
 
  Unless otherwise indicated in the applicable Prospectus Supplement, payment
of principal of, premium, if any, and interest, if any, on Debt Securities in
bearer form will be made payable, subject to any applicable laws and
regulations, at such office outside the United States as specified in the
Prospectus Supplement and as the Issuer may designate from time to time, at
the option of the holder, by check or by transfer to an account maintained by
the payee with a bank located outside the United States. Unless otherwise
indicated in the applicable Prospectus Supplement, payment of interest and
certain additional amounts on Debt Securities in bearer form will be made only
against surrender of the coupon relating to the applicable Interest Payment
Date. No payment with respect to any Debt Security in bearer form will be made
at any office or agency of the Issuer in the United States or by check mailed
to any address in the United States or by transfer to an account maintained
with a bank located in the United States.
 
GLOBAL DEBT SECURITIES
 
  The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities ("Global Debt Securities") that will be
deposited with, or on behalf of, a depositary (the "Depositary") identified in
the Prospectus Supplement relating to such series. Global Debt Securities may
be issued in either registered or bearer form and in either temporary or
permanent form. Unless and until it is exchanged in whole or in part for
individual certificates evidencing Debt Securities in definitive form
represented thereby, a Global Debt Security may not be transferred except as a
whole by the Depositary for such Global Debt Security to a nominee of such
Depositary or by a nominee of such Depositary to such Depositary or another
nominee of such Depositary or by such Depositary or any such nominee to a
successor of such Depositary or a nominee of such successor.
 
  The specific terms of the depositary arrangement with respect to a series of
Global Debt Securities, and certain limitations and restrictions relating to a
series of bearer Global Debt Securities, will be described in the Prospectus
Supplement relating to such series.
 
RESTRICTIVE COVENANTS
 
  The Indentures do not contain restrictive covenants, but the indenture
supplement or amendment entered into at the time of the issuance of any Debt
Securities may contain such restrictions on the Issuer and its operations. The
applicable Prospectus Supplement will describe any restrictive covenants
applicable to the Debt Securities that are issued thereunder.
 
OUTSTANDING DEBT SECURITIES
 
  Unless otherwise indicated in the applicable Prospectus Supplement, in
determining whether the holders of the requisite principal amount of
Outstanding Debt Securities have given any request, demand, authorization,
direction, notice, consent or waiver under the Indentures: (a) the portion of
the principal amount of an Original Issue Discount Security that shall be
deemed to be Outstanding for such purposes shall be that portion of the
principal amount thereof that could be declared to be due and payable pursuant
to the terms of such Original Issue Discount Security as of the date of such
determination; (b) the principal amount of any Indexed Security shall be the
principal face amount of such Indexed Security determined on the date of its
original issuance; and (c) any Debt Security owned by the Issuer or any
obligor on such Debt Security or any Affiliate of the Issuer or such other
obligor, shall be deemed not to be outstanding.
 
 
                                       8
<PAGE>
 
MODIFICATION AND WAIVER
 
  The Issuer may amend the Indentures with the written consent of the holders
of a majority in principal amount of the respective Debt Securities
outstanding thereunder. However, without the consent of each Holder affected,
an amendment may not: (a) reduce the amount of Debt Securities whose holders
must consent to an amendment; (b) reduce the rate or change the time of
payment of interest on any Debt Securities; (c) reduce the principal of or
change the fixed maturity of Debt Securities; (d) make any Debt Securities
payable in money other than that stated in the definitive notes representing
such Debt Securities; (e) change the provisions of the respective Indenture
regarding the right of a majority of the Holders to waive defaults under such
Indenture or impair the right of any Holder to institute suit for the
enforcement of any payment of principal and interest on the Debt Securities on
and after their respective due dates; (f) make any change that adversely
affects the right to convert or exchange any Convertible Debt Securities; or
(g) make any change to the provisions of the respective Indenture regarding
subordination and seniority of the Debt Securities that adversely affects the
rights of any Holders.
 
SPECIAL TERMS RELATING TO SUBORDINATED DEBT SECURITIES
 
  Upon any distribution of assets of the Issuer resulting from any
dissolution, winding up, liquidation or reorganization, payments on
Subordinated Debt Securities are to be subordinated, to the extent provided in
the Subordinated Indenture, in right of payment to the prior payment in full
of all Senior Indebtedness, but the obligation of the Issuer to make payments
on the Subordinated Debt Securities will not otherwise be affected. No payment
on Subordinated Debt Securities may be made at any time when there is a
default in the payment of any principal, premium, interest, Additional Amounts
or sinking fund of or on any Senior Indebtedness. Holders of Subordinated Debt
Securities will be subrogated to the rights of holders of Senior Indebtedness
to the extent of payments made on Senior Indebtedness upon any distribution of
assets in any such proceedings out of the distributive shares of Subordinated
Debt Securities. By reason of such subordination, in the event of a
distribution of assets upon insolvency, certain creditors of the Issuer may
recover more, ratably, than holders of Subordinated Debt Securities.
 
  The Prospectus Supplement relating to any Subordinated Debt Securities will
set forth the aggregate amount of Senior Indebtedness outstanding as of the
most recent date practicable and any limitations on the issuance of additional
Senior Indebtedness. As of the date of this Prospectus, there is no limitation
on the amount of Senior Indebtedness that may be issued by the Trust or the
Operating Partnership.
 
CONVERSION OR EXCHANGE
 
  The holders of Debt Securities of a specified series that are convertible
into or exchangeable for other Securities ("Convertible Debt Securities") will
be entitled at certain times specified in the Prospectus Supplement relating
to such Convertible Debt Securities, subject to prior redemption, exchange,
repayment or repurchase, to convert or exchange any Convertible Debt
Securities of such series into such other Securities, at the conversion price
set forth in such Prospectus Supplement, subject to adjustment and to such
other terms as are set forth in such Prospectus Supplement. Any such
conversion or exchange of Convertible Debt Securities will be further subject
to the applicable terms and conditions set forth in the Indentures, as
supplemented or amended from time to time.

Securities is based on current law, is for general information only and is not
tax advice. The tax treatment of holder of any of the Securities will vary
depending on the terms of the specific Securities acquired or held by such
holder as well as such holder's particular situation, and this summary does
not attempt to address any aspects of federal income taxation relating to
holders of the Securities. Certain federal income tax consideration relevant
to holders of Securities will be provided on the applicable Prospectus
Supplement relating thereto.
 
  EACH PROSPECTIVE PURCHASER OF SECURITIES 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 SECURITIES 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
 
  The Trust and the Operating Partnership believe that, commencing with the
Trust's taxable year ended December 31, 1994, the Trust has been organized and
was and is operated in such a manner as to qualify as a real estate investment
trust under Sections 856 through 860 of the Code. The Trust intends to
continue to operate in such a manner, but no assurance can be given that it
will operate in a manner so as to qualify or remain qualified.
 
  The sections of the Code relating to qualification and operation as a real
estate investment trust are highly technical and complex. The following sets
forth the material aspects of the Code sections that govern the federal income
taxation of a real estate investment trust. 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 has acted as counsel to the Trust in connection
with the Trust's election to be taxed as a real estate investment trust.
 
  Because the Trust qualifies for taxation as a real estate investment trust,
generally it will not be subject to federal corporate income taxes on its net
income that is currently distributed 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 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 real estate investment trust upon
the default by a debtor with respect to indebtedness secured by the property
or upon the default by a lessee where the real estate investment trust 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), such income will be subject to a 100% tax. The Operating
 
                                      12
<PAGE>
 
Partnership does not anticipate recognizing gross income from either of the
"third" or "fourth" immediately foregoing sources, although Liberty Property
Development Corporation ("Liberty Development"), the corporation which owns
undeveloped land and with respect to which the Operating Partnership owns 8.0%
of its voting common stock and 100% of its non-voting common stock, may
realize gross income from such sources. 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 real estate
investment trust because certain other requirements have been met, it will be
subject to a 100% tax on the net income attributable to the greater of the
amount by which the Trust fails the 75% test or the 95% test in the taxable
year, i.e., the excess of the Trust's gross income in the category over the
qualifying income in the category, multiplied by a fraction generally intended
to reflect Trust profitability. Sixth, if the Trust should fail to distribute
during each calendar year at least the sum of (i) 85% of its real estate
investment trust ordinary income for such year, (ii) 95% of its real estate
investment trust 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 the 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 "Built-In Gain Rule"). 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.
 
  Wolf, Block, Schorr and Solis-Cohen has opined that, commencing with the
Trust's taxable year ended December 31, 1994, the Trust has been organized in
conformity with the requirements for qualification as a real estate investment
trust, and its method of operation will enable it to meet the requirements for
qualification and taxation as a real estate investment trust under the Code.
It must be emphasized that the opinion of Wolf, Block, Schorr and Solis-Cohen
is based on certain assumptions and representations made by the Trust and the
Operating Partner as to factual matters. Moreover, such qualification and
taxation as a real estate investment trust 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. Accordingly,
no assurance can be given 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 real estate investment
trust, see "--Failure to Qualify."
 
REQUIREMENTS FOR QUALIFICATION
 
  The Code defines a real estate investment trust 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 company subject to certain
provisions of the Code; (5) the beneficial ownership of 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. Conditions (5) and (6) will not
apply until after the first taxable year for which an election is made by the
Trust to be taxed as a real estate investment trust. Generally, real estate
investment trust shares held by a pension fund are treated as held
proportionately by its beneficiaries.
 
                                      13
<PAGE>
 
  The Trust has issued sufficient shares to allow it to satisfy conditions (5)
and (6) above. In making the "five or fewer individual" determination,
interests in the Operating Partnership that can be converted into shares of
the Trust are presumed to be converted and represent the appropriate number of
outstanding shares. In addition, the Trust's 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 Trust's Registration
Statement on Form 8-A, which is 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 real estate investment trust. A qualified REIT subsidiary is a
corporation 100% of the stock of which is held by the real estate investment
trust at all times during the existence of the corporation. 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 real estate investment trust which is a partner in a
partnership, Treasury Regulations provide that the real estate investment
trust 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 real
estate investment trust for purposes of Section 856 of the Code, including
satisfying the gross income tests and the asset tests described below. 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.
 
INCOME TESTS
 
  For the Trust to maintain its qualification as a real estate investment
trust, the Trust's gross income 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 or temporary 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, short-
term gain from the sale or other disposition of stock or securities that do
not constitute dealer property, 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 real estate investment trust
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. 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 real estate
investment trust 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 real estate investment trust, or an
owner of 10% or more of the real estate investment trust, directly or
constructively, owns 10% or more of
 
                                      14
<PAGE>
 
such tenant (a "Related Party Tenant"). The IRS has interpreted this rule to
treat a portion of rents received or accrued by a real estate investment trust
from a prime tenant where a sublessee is a Related Party Tenant, as from 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 real estate investment trust 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 from whom the real
estate investment trust 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 indicated
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. To the extent that the Trust does provide services to tenants, it
will render those services through one or more independent contractors from
whom the Trust derives no revenue.
 
  The Trust is a self-managed real estate investment trust; i.e., the
Operating Partnership performs all of the management and leasing functions
with respect to the properties it owns itself and not through the use of an
independent contractor 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." The Trust may provide property management and leasing services
to third parties and will provide services to an affiliated entity for a fee,
although the Trust does not expect that the revenue derived from such services
would cause it to fail to satisfy the 75% or 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 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.
 
  Any gross income derived from a prohibited transaction is taken into account
in applying the 30% income test necessary to maintain the Trust's
qualification as a real estate investment trust (and the net income from that
transaction is subject to a 100% tax). The Operating Partnership and the Trust
believe that no asset owned by the Operating Partnership, the Property
Partnerships or the Trust is held for sale to customers and that any sale of
any property will not be in the ordinary course of business of the Operating
Partnership, the relevant Property Partnership or the Trust. Whether property
is held "primarily for sale to customers in the ordinary course of a trade or
business" depends, however, on the facts and circumstances in effect from time
to time, including those related to a particular property. The Trust and the
Operating Partnership will attempt to comply with the terms of safe-harbor
provisions in the Code prescribing when asset sales will not be characterized
as prohibited transactions. Complete assurance cannot be given, however, that
the Trust can comply with the safe-harbor provisions of the Code or avoid
owning property that may be characterized as property held "primarily for sale
to customers in the ordinary course of business." Assets owned by an
affiliated entity may constitute property held for sale, although the Trust
will own an interest solely as a shareholder in such entity.
 
  As noted above, the Operating Partnership owns 8% of the voting common stock
and 100% of the non-voting common stock of Liberty Development, a corporation
that is taxable as a regular corporation. Income earned by and taxed to
Liberty Development may constitute income that would not qualify under the
three REIT income tests described above if earned directly by the Trust. As a
consequence of the corporate structure, the income will be earned by and
taxable to Liberty Development, rather than the Trust or the Operating
Partnership.
 
                                      15
<PAGE>
 
The Operating Partnership will receive income from Liberty Development only in
the form of interest or dividend income. Although interest and dividend income
ordinarily are qualifying income under the 95% gross income test, the IRS has
instituted a "no-ruling" policy under which it will not issue a ruling with
respect to whether this form of ownership arrangement constitutes ownership of
more than 10% of the voting securities of an issuer, whether the interest and
dividends are characterized as interest and dividends for purposes of the 75%
and 95% tests, and whether the activities of the corporate entity are taken
into account in determining whether the REIT has income from a prohibited
transaction.
 
  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. The Trust can maintain its
classification as a real estate investment trust, notwithstanding such
failure, if it is entitled to relief under a statutory safe harbor applying to
such cases. 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. This statutory relief is available only for failures to satisfy the
75% and 95% gross income tests and no such relief is available for a failure
to satisfy the 30% gross income test. In such case, the Trust would cease to
qualify as a real estate investment trust.
 
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 (excluding the stock of a qualified
REIT subsidiary, of which the REIT is required to own all of the stock, or of
another REIT).
 
  As noted above, the Operating Partnership will own 8.0% of the voting common
stock and 100% of the non-voting common stock of Liberty Development. By
virtue of its ownership of partnership interests in the Operating Partnership,
the Trust will own its pro rata share of assets of the Operating Partnership,
including the securities of such subsidiaries as described above. The
Operating Partnership will not own more than 10% of the voting securities of
Liberty Development and, therefore, the Trust will not own more than 10% of
the voting securities of Liberty Development. In addition, the Trust has
determined, 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,
that its pro rata share of the securities of such subsidiaries to be held by
the Operating Partnership will 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, in rendering its opinion as to the
qualification of the Trust as a real estate investment trust, is relying
solely on the representations of the Trust regarding the value of Liberty
Development. As noted above, this requirement must be satisfied not only on
the date that the Trust acquired securities in Liberty Development, but also
each time the Trust increases its ownership of securities of such subsidiary
(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
 
                                      16
<PAGE>
 
occur, there can be no assurance that such steps will always be successful or
will not require a reduction in the Operating Partnership's overall interest
in Liberty Development.
 
  As set forth above, the ownership of more than 10% of the voting securities
of any one issuer by a real estate investment trust is prohibited by the asset
tests. However, if the Trust's subsidiaries are "qualified REIT subsidiaries"
as defined in the Code, such subsidiaries will not be treated as separate
corporations for federal income tax purposes. Thus, the Trust's ownership of
the stock of a "qualified REIT subsidiary" will not cause the Trust to fail
the asset tests. The Trust believes that it has met the three tests related to
the classification of its assets at each of the relevant testing points since
its inception.
 
  After initially meeting the asset tests at the close of any quarter, the
Trust will not lose its status as a real estate investment trust 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. As noted above, one of the requirements for qualification as a
REIT is that the Trust not own more than 10 percent of the outstanding voting
securities of any issuer (other than stock in a qualified REIT subsidiary or
another REIT). In compliance with this requirement, the Operating Partnership
owns only 8% of the voting common stock, although it owns 100% of the non-
voting common stock, of Liberty Development. It is possible that the IRS would
contend that the Trust, through its interest in the Operating Partnership,
should be viewed as owning more than 10% of the voting securities of Liberty
Development because of its substantial economic position in Liberty
Development and the close business relationship between the two entities. If
the IRS were successful in this contention, the Trust's status as a REIT would
be terminated and the Trust would be subject to federal and state corporate
income tax on its net income, determined without any deduction on account of
dividends paid to shareholders. The Operating Partnership does not posses the
requisite power to elect or designate a member of the Board of Directors,
there is no understanding or arrangement permitting the Trust to exercise
voting power or control over the voting common stock not owned by it, and the
Trust does not believe that it will be viewed as owning in excess of 10% of
the voting securities of Liberty Development.
 
ANNUAL DISTRIBUTION REQUIREMENTS
 
  The Trust, to qualify as a real estate investment 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 thereon 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 depreciated property which exceeds its
allocable
 
                                      17
<PAGE>
 
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 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.
 
  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.
 
  Pursuant to applicable Treasury Regulations, in order to elect to be taxed
as a real estate investment trust, the Trust must maintain certain records and
timely request certain information from its shareholders designed to disclose
the actual ownership of its stock. The Trust believes it has complied, and
intends to continue to comply, with such requirements.
 
FAILURE TO QUALIFY
 
  If the Trust fails to qualify for taxation as a real estate investment trust
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 real estate investment trust 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 real estate investment trust 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.

  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")
and represents the view of Wolf, Block, Schorr and Solis-Cohen. The discussion
does not purport to address the impact of state or local tax laws or any
federal tax laws other than income tax laws.
 
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 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. 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
 
                                      19
<PAGE>
 
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, the
classification of the Operating Partnership and each of the Property
Partnerships should not be subject to challenge for any period prior to
January 1, 1997.
 
  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 real estate investment trust. As a consequence,
the Trust would be subject to tax (including any applicable alternative
minimum tax) on its taxable income at regular corporate income tax rates.
Distributions to shareholders in any year in which the Trust fails to qualify
as a real estate investment trust would not be deductible by the Trust and
would, to the extent of the Trust's current and accumulated earnings and
profits, be subject to taxation as dividends at ordinary income tax rates.
Subject to certain limitations, corporate distributees might be eligible for
the dividends received deduction in such event. Unless entitled to relief
under specific statutory provisions, the Trust would also be disqualified from
electing to be treated as a real estate investment trust for the four taxable
years following the year in which it ceased to qualify as a real estate
investment trust. 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.
 
  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
 
                                      20
<PAGE>
 
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 an excess at such time of basis for book purposes over basis
for tax purposes 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 will be limited by the so-called "ceiling rule" and
will 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.
 
 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 certain undertakings by limited partners of the
Operating Partnership, the Subordinated Debentures issued by the Operating
Partnership are allocated for purposes of Section 752 of the Code
disproportionately in favor of certain limited partners.
 
                                      21

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.
 
  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. See "--Requirements for Qualification"
and "--Income Tests." Such prohibited transaction income may also have an
adverse effect upon the Trust's ability to satisfy the income tests for real
estate investment trust status. See "--Requirements For Qualification" and "--
Income Tests," above. 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
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.
 
                             PLAN OF DISTRIBUTION
 
  The Trust and/or the Operating Partnership, as the case may be, may sell the
Securities being offered hereby: (a) directly to purchasers; (b) through
agents; (c) through underwriters; (d) through dealers; or (e) through a
combination of any such methods of sale. The Securities may also be used as
all or part of the consideration to be paid by the Trust or the Operating
Partnership for the acquisition of non-operating assets for which financial
statements would not be required to be filed with the Commission, or in
exchange for units of limited partnership interest of the Operating
Partnership. In addition, Common Shares may be offered hereby in exchange for
certain debt securities of the Operating Partnership that are exchangeable for
such Common Shares.
 
  The distribution of the Securities may be effected from time to time in one
or more transactions: (a) at a fixed price or at final prices, which may be
changed; (b) at market prices prevailing at the time of sale; (c) at prices
related to such prevailing market prices; or (d) at negotiated prices. Offers
to purchase Securities may be solicited directly by the Trust or the Operating
Partnership, as the case may be, or by agents designated by the Trust or the
Operating Partnership, as the case may be, from time to time. Any such agent,
which may be deemed to be an underwriter as that term is defined in the
Securities Act, involved in the offer or sale of the Securities in respect of
which this Prospectus is delivered will be named, and any commissions payable
by the Trust or the Operating Partnership, as the case may be, to such agent
will be set forth, in the applicable Prospectus Supplement.
 
  If an underwriter is, or underwriters are, utilized in the offer and sale of
Securities in respect of which this Prospectus and the accompanying Prospectus
Supplement are delivered, the Trust and/or the Operating Partnership will
execute an underwriting agreement with such underwriter(s) for the sale to it
or them and the name(s) of the underwriter(s) and the terms of the transaction
will be set forth in such Prospectus Supplement, which will be used by the
underwriter(s) to make resales of the Securities in respect of which this
Prospectus and such Prospectus Supplement are delivered to the public.
 
  If a dealer is utilized in the sale of the Securities in respect of which
this Prospectus is delivered, the Trust and/or the Operating Partnership will
sell such Securities to the dealer, as principal. The dealer may then resell
such Securities to the public at varying prices to be determined by such
dealer at the time of resale.
 
 
                                      22

  Certain of the underwriters, dealers or agents utilized by the Trust and/or
the Operating Partnership in any offering hereby may be customers of,
including borrowers from, engage in transactions with, and perform services
for, the Trust and/or the Operating Partnership or one or more of their
respective affiliates in the ordinary course of business. Underwriters,
dealers, agents and other persons may be entitled, under agreements which may
be entered into with the Trust or the Operating Partnership, as the case may
be, to indemnification against certain civil liabilities, including
liabilities under the Securities Act.
 
                                LEGAL OPINIONS
 
  Wolf, Block, Schorr and Solis-Cohen, Philadelphia, Pennsylvania, has
rendered an opinion with respect to the legality of the Securities to be
issued by the Operating Partnership. Weinberg & Green LLC, Baltimore,
Maryland, has rendered an opinion with respect to the legality of the
Securities to be issued by the Trust. The statements in this Prospectus under
the caption "Federal Income Tax Considerations with Respect to the Trust and
the Operating Partnership" and the other statements herein relating to the
Trust's qualification as a real estate investment trust will be passed upon
for the Trust by Wolf, Block, Schorr and Solis-Cohen, although such firm has
rendered no opinion as to matters involving the imposition of non-U.S. taxes
on the operations of, and distributions of payments from, its United Kingdom
affiliate. Michael M. Dean, a partner of Wolf, Block, Schorr and Solis-Cohen,
is the sole trustee of irrevocable trusts established by three of the Trust's
senior executives for the benefit of their respective children. Each of such
trusts received limited partnership interests in the Operating Partnership in
connection with the Company's formation in exchange for interests in the Rouse
Group owned by such trusts.

Item 15.  Indemnification of Directors and Officers.

The Trust

     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

                                      II-1
<PAGE>
 
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.

The Operating Partnership

     Section 8570 of the Pennsylvania Revised Uniform Limited Partnership Act
authorizes the Operating Partnership to indemnify any partner or other person
from and against any and all claims and demands whatsoever, unless it is
determined by a court that the act or omission giving rise to the claim of
indemnification constituted willful misconduct or recklessness.

     Reference is made to Section 7.8 of the Operating Partnership's First
Restated and Amended Limited Partnership Agreement (the "Partnership
Agreement"), a copy of which is filed as Exhibit 3.1 to the Registration
Statement, which provides for indemnification of the general partners and
others.  Section 7.8(d) of the Partnership Agreement authorizes the Operating
Partnership to purchase and maintain insurance on behalf of the general partner
and others against any liability that may be asserted against or expenses that
may be incurred by such person regardless of whether the Operating Partnership
would have the power to indemnify such person against liability under the
Partnership Agreement.

     Reference is made to Section 7.9 of the Partnership Agreement which limits
the general partner's liability for monetary or other damages.

Item 17.  Undertakings.

     (a)  The undersigned Registrants hereby undertake:

          (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) 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% 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 the undertakings set forth in clauses (i) and 
     (ii) of this paragraph shall not apply if the information required to be
     included in such post-effective amendments is contained in periodic reports
     filed by the Registrants 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 Registrants hereby undertake that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrants' 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 directors, officers or controlling persons of
the Registrants pursuant to the foregoing provisions, or otherwise, the
Registrants have 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 payment by the Registrants of expenses
incurred or paid by a director, officer or controlling person of either
Registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the Registrants will, unless in the opinion of
their counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
either of them is against public policy as expressed in the Act and will be
governed by the final adjudication of such issue.

     (d)  The undersigned Registrants hereby undertake that:

          (1)  For purposes of determining any liability under the Securities 
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A under the Securities
     Act and contained in a form of prospectus filed by the Registrants pursuant
     to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be
     deemed to be part of this Registration Statement as of the time it was
     declared effective.

          (2)  For the purpose of determining any liability under the 
     Securities Act, each post-effective amendment that contains a form of
     prospectus 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.

     (e)  The undersigned Registrants hereby undertake to file an application 
for the purpose of determining the eligibility of the trustee to act under
subsection (a) of Section 310 of the Trust Indenture Act of 1939 as amended (the
"TIA") in accordance with the rules and regulations prescribed by the Commission
under Section 305(b)(2) of the TIA.

             THIRD AMENDMENT TO AGREEMENT OF LIMITED PARTNERSHIP OF
                      LIBERTY PROPERTY LIMITED PARTNERSHIP


     THIS THIRD AMENDMENT (the "Amendment"), entered into as of January 1, 1996,
to that certain Agreement of Limited Partnership dated as of June 23, 1994, as
amended by First Amendment dated as of March 1, 1995, and Second Amendment dated
as of June 19, 1995 (collectively, the "Agreement"), of LIBERTY PROPERTY LIMITED
PARTNERSHIP, a Pennsylvania limited partnership (the "Partnership").
Capitalized terms used herein shall have the meanings given to them in the
Agreement.

                                   BACKGROUND
                                   ----------

     The General Partner and the Limited Partners are parties to the Agreement
with respect to the Partnership.

     Pursuant to the authority granted to the General Partner in Article XIV of
the Agreement, the General Partner desires to amend Exhibit A to the Agreement
in order to reflect the division of the Partnership Interest jointly held by
Rebecca H. and David L. Lingerfelt.

     NOW THEREFORE, the General Partner and the Limited Partners, acting through
the General Partner as their attorney-in-fact pursuant to the authority granted
in Section 10.7 of the Agreement, agree as follows, intending to be legally
bound:

     1.  Exhibit A to the Agreement is hereby amended to reflect the division of
the 16,152 units jointly held by Rebecca H. and David L. Lingerfelt such that
Rebecca H. Lingerfelt shall be allocated 8,076 units in her name, with all
appurtenant rights and responsibilities, and David L. Lingerfelt shall be
allocated 8,076 units in his name, with all appurtenant rights and
responsibilities.  The units so allocated to David L. Lingerfelt shall be added
to the 22,598 units already held by him in his name for a total of 30,674 units
held by him in his name.  The Percentage Interests held by Rebecca H. Lingerfelt
and David L. Lingerfelt as Limited Partners shall be readjusted between them
accordingly.

     2.  Except as expressly modified hereby, the Agreement shall continue in

             Re:  Liberty Property Limited Partnership
                  Registration Statement on Form S-3
                  ------------------------------------

Ladies and Gentlemen:

     As counsel for Liberty Property Limited Partnership, a Pennsylvania limited
partnership (the "Partnership"), we have assisted in the preparation of a
Registration Statement on Form S-3 (the "Registration Statement") to be filed
with the Securities and Exchange Commission (the "Commission") jointly by the
Partnership and Liberty Property Trust, a Maryland real estate investment trust
(the "Trust"). The Registration Statement relates to the issuance and sale from
time to time, pursuant to Rule 415 of the General Rules and Regulations of the
Commission promulgated under the Securities Act of 1933, as amended (the
"Securities Act"), of securities with an aggregate initial public offering price
of up to $850,000,000 or the equivalent thereof in one or more foreign
currencies or composite currencies, including securities of the Partnership with
an aggregate initial public offering price up to $300,000,000 or the equivalent
thereof in one or more foreign currencies or composite currencies (the
"Registered Partnership Securities") and securities of the Trust with an
aggregate initial public offering price of up to $550,000,000 or the equivalent
thereof in one or more foreign currencies or composite currencies. The
Registered Partnership Securities consist of (i) debt securities of the
Partnership, which may be any of senior secured debt securities, senior
unsecured debt securities, senior subordinated debt securities or subordinated
debt securities, in one or more series (the "Partnership Debt Securities"),
which in each case are to be issued under either a senior indenture (the "Senior
Indenture") or a subordinated indenture (the "Subordinated Indenture" and,
together with the Senior Indenture, the "Indentures") to be entered into by the
Partnership

and an institution to be designated prior to the issuance of any Partnership
Debt Securities under such Indenture to serve as trustee thereunder (a "Trustee"
and, collectively with the trustees, if any, under other Indentures, the
"Trustees") and, if such Partnership Debt Securities are to be issued with
"Trust Guaranties," as defined in the Registration Statement ("Trust
Guaranties"), the Trust; and (ii) guaranties of the Partnership (the
"Partnership Guaranties") to be issued in connection with "Trust Debt
Securities," as defined in the Registration Statement ("Trust Debt Securities"),
which in each case are to be issued under an Indenture to be entered into by the
Trust, the Trustee under such Indenture and the Partnership prior to the
issuance of any Trust Debt Securities or Partnership Guaranties under such
Indenture.

     This opinion is being delivered in accordance with the requirements of
Item 601(b)(5) of Regulation S-K promulgated under the Securities Act.

     For the purpose of rendering this opinion, we have examined (i) the
Registration Statement; (ii) the form of Senior Indenture being incorporated by
reference as an exhibit to the Registration Statement (the "Base Senior
Indenture"); (iii) the form of Subordinated Indenture being incorporated by
reference as an exhibit to the Registration Statement (the "Base Subordinated
Indenture"); (iv) the Certificate of Limited Partnership of the Partnership, as
amended to date (the "Certificate of Limited Partnership"); (iv) the First
Amended and Restated Agreement of Limited Partnership of the Partnership, as
amended to date (the "Agreement of Limited Partnership"); and (v) certain
resolutions adopted by the Board of Trustees of the Trust (the "Board of
Trustees"), in the Trust's capacity as the sole general partner of the
Partnership, relating to the Registered Partnership Securities. We have also
examined originals or copies, certified or otherwise identified to our
satisfaction, of such records of the Partnership and the Trust and such
agreements, certificates of public officials, certificates of officers or other
representatives of the Partnership and the Trust and others and such other
documents, certificates and records as we have deemed necessary or appropriate
as a basis for the opinions set forth herein.

        In our examination, we have assumed without independent verification (i)
the legal capacity of all natural persons; (ii) the genuineness of all
signatures; (iii) the authenticity of all documents submitted to us as
originals; (iv) the conformity to original documents of all documents submitted
to us as certified, conformed or photostatic copies and the authenticity of the
originals of such latter documents; and (v) the power and authority of all
persons other than the Partnership signing such documents to execute, deliver
and perform such documents, and the valid authorization, execution and delivery
of such documents by such other persons. As to any facts material to the
opinions expressed herein which have not been independently established or
verified, we have relied upon oral or written statements and representations of
officers or other representatives of the Partnership and others.

        We do not express any opinion as to the laws of any jurisdiction other
than the Commonwealth of Pennsylvania and the federal laws of the United States
of America to the
<PAGE>

extent referred to specifically herein. The Registered Partnership Securities
may be issued from time to time on a delayed or continuous basis, and this
opinion is limited to the laws, including applicable rules and regulations, in
effect on the date hereof. We assume no obligation to update this opinion.

     Based upon and subject to the foregoing, such examinations of law and
such other matters as we have deemed relevant under the circumstances, we are of
the opinion that, as of the date hereof:

     1.  The respective forms of the Base Senior Indenture and the Base
         Subordinated Indenture (collectively, the "Base Indentures") have been
         duly authorized by the Partnership, through the action of the Board of
         Trustees, in the Trust's capacity as the sole general partner of the
         Partnership. Each of the Base Indentures, and each other Indenture in
         the form of either of the Base Indentures, as modified in accordance
         with duly adopted resolutions of the Board of Trustees, in the Trust's
         capacity as the sole general partner of the Partnership, to reflect the
         additional terms applicable to the Registered Partnership Securities to
         which such Indenture relates, when executed and delivered by the
         Partnership and duly executed and delivered by the Trustee thereunder
         (and, in the case of an Indenture that relates to Partnership
         Guaranties, the Trust), will be a valid and binding agreement,
         enforceable against the Partnership in accordance with its terms,
         except to the extent that enforcement thereof may be limited by (a)
         bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium
         or other similar laws now or hereafter in effect relating to or
         affecting creditors' rights generally, (b) general principles of equity
         (regardless of whether enforceability is considered in a proceeding at
         law or in equity), (c) requirements that a claim with respect to any
         Registered Partnership Securities denominated other than in United
         States dollars (or a judgment denominated other than in United States
         dollars in respect of such claim) be converted into United States
         dollars at a rate of exchange prevailing on a date determined pursuant
         to applicable law, and (d) governmental authority to limit, delay or
         prohibit the making of payments outside the United States or in foreign
         currency or composite currency.

     2.  With respect to any Registered Partnership Securities, when (i) if such
         Registered Partnership Securities are to be sold pursuant to a firm
         commitment underwritten offering, the underwriting agreement with
         respect to such Registered Partnership Securities (the "Underwriting
         Agreement") has been duly authorized, executed and delivered by the
         Partnership through the action of the Trust in its capacity as the sole
<PAGE>

         general partner of the Partnership and the other party or parties
         thereto; (ii) if such Registered Partnership Securities are to be sold
         on an agency basis, the distribution agreement with respect to such
         Registered Partnership Securities (the "Distribution Agreement") has
         been duly authorized, executed and delivered by the Partnership through
         the action of the Trust in its capacity as the sole general partner of
         the Partnership and the other party or parties thereto; (iii) the Board
         of Trustees, including any appropriate committee appointed thereby, in
         the Trust's capacity as the sole general partner of the Partnership
         (and, in the case of Partnership Guaranties, the Trust in its capacity
         as issuer of the Trust Debt Securities to which such Partnership
         Guaranties relate), and the appropriate officers of the Partnership and
         the Trust have taken all necessary Partnership or Trust action, as the
         case may be, to approve the issuance and terms of such Registered
         Partnership Securities (and, in the case of Partnership Guaranties, the
         Trust Debt Securities to which such Partnership Guaranties relate) and
         related matters; (iv) the terms of such Registered Partnership
         Securities (and, in the case of Partnership Guaranties, the Trust Debt
         Securities to which such Partnership Guaranties relate) and of their
         issuance and sale have been duly established in conformity with the
         Indenture relating thereto so as not to violate any applicable law, the
         Certificate of Limited Partnership or the Agreement of Limited
         Partnership or result in a default under or breach of any agreement or
         instrument binding upon the Partnership (or, in the case of Partnership
         Guaranties, the Partnership or the Trust), and so as to comply with any
         requirement or restriction imposed by any court or governmental body
         having jurisdiction over the Partnership (or, in the case of
         Partnership Guaranties, the Partnership or the Trust); (v) the
         applicable Indenture has been duly executed and delivered by the
         Partnership (and, in the case of Partnership Guaranties, the Trust),
         through the action of the Trust in its capacity as the sole general
         partner of the Partnership (and, in the case of Partnership Guaranties,
         in its capacity as issuer of the Trust Debt Securities to which such
         Partnership Guaranties relate), and the Trustee thereunder; and (vi)
         such Registered Partnership Securities (and, in the case of Partnership
         Guaranties, the Trust Debt Securities to which such Partnership
         Guaranties relate) have been duly executed and authenticated in
         accordance with the provisions of the applicable Indenture and duly
         delivered to the purchasers thereof upon payment of the agreed-upon
         consideration therefor, such Registered Partnership Securities, when
         issued and sold in accordance with the applicable Indenture and the
         related Underwriting Agreement or Distribution Agreement, if any, or
         any other duly authorized, executed and delivered applicable purchase
         agreement, will be valid and binding obligations of the Partnership,

         enforceable against the Partnership in accordance with their respective
         terms, except to the extent that enforcement thereof may be limited by
         (a) bankruptcy, insolvency, reorganization, fraudulent transfer,
         moratorium or other similar laws now or hereafter in effect relating to
         or affecting creditors' rights generally, (b) general principles of
         equity (regardless of whether enforceability is considered in a
         proceeding at law or in equity), (c) requirements that a claim with
         respect to any Registered Partnership Securities denominated other than
         in United States dollars (or a judgment denominated other than in
         United States dollars in respect of such claim) be converted into
         United States dollars at a rate of exchange prevailing on a date
         determined pursuant to applicable law, and (d) governmental authority
         to limit, delay or prohibit the making of payments outside the United
         States or in foreign currency or composite currency.

     We note that, as of the date hereof, a judgment for money in an action
based on a Registered Partnership Security denominated in a foreign currency,
currency unit or composite currency in a federal or state court in the United
States ordinarily would be enforced in the United States only in United States
dollars. The date used to determine the rate of conversion of the foreign
currency, currency unit or composite currency in which a particular Registered
Partnership Security is denominated into United States dollars will depend upon
various factors, including which court renders the judgment.

     We hereby consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement. We also consent to the reference to our
firm under the heading "Legal Opinions" in the Registration Statement. In giving
this consent, we do not admit that we are in the category of persons whose
consent is required under Section 7 of the Securities Act or the Rules and
Regulations of the Commission.


                                 Sincerely yours,

          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 shelf registration of up to
U.S. $850,000,000 (or the equivalent) of Trust Debt Securities, Preferred
Shares, Depositary Shares, Common Shares, Trust Debt Warrants, Preferred Shares
Warrants, Common Shares Warrants, and Trust Guaranties (each as defined in the
above-referenced Registration Statement)(collectively referred to as the "Trust
Securities") proposed to be offered by the Company from time to time and certain
securities proposed to be offered by Liberty Property Limited Partnership, a
Pennsylvania limited partnership, from time to time, in one or more series,
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"), a Prospectus and one or more Prospectus supplements.
(The Trust Debt Warrants, Preferred Shares Warrants, and Common Shares Warrants
are referred to collectively as the "Trust Warrants.")

          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.  A copy of the S-3 Registration Statement, as filed by the Company
              with the Securities and Exchange Commission (the "Commission")
              under the Securities Act of 1933 (the "Act");

          b.  The prospectus contained in the S-3 Registration Statement (the
              "S-3 Prospectus");

                                            Page 2

          c.  The Amended and Restated Declaration of Trust of the Company (the
              "Declaration of Trust");

          d.  The Bylaws of the Company;  and

          e.  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 opinions 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.  Liberty Property Limited Partnership (the "Partnership") is a
limited partnership validly existing and in good standing under the laws of its
state of formation;

          5.  There will be no changes in applicable law between the date of
this opinion and any date of issuance or delivery of the Trust Securities,
including without limitation, any Trust Securities that may be issued upon
conversion or exchange of any of the Trust Securities;

          6.  At the time of delivery of the Trust Securities, all contemplated
additional actions shall have been taken and the authorization of the issuance
of the Trust Securities will not have been modified or rescinded;
<PAGE>

                                        Liberty Property Trust
                                        ___________, 1997
                                        Page 3

          7.  The terms of all Trust Securities to be established subsequent to
the date of this opinion; the issuance, execution and delivery of the Trust
Securities; and the compliance by the Company with the terms of the Trust
Securities, 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;

          8.  The consideration received or proposed to be received for the
issuance and sale or reservation for issuance of any offering of common shares
of the Company as contemplated by each of the S-3 Registration Statement, the S-
3 Prospectus, and the applicable supplement or supplements to the S-3 Prospectus
is not less than the par value per share; and

          9.  The aggregate number of shares of the Company which would be
outstanding after the issuance or reservation for issuance of any preferred
shares or common shares of the Company, whether to effect an issuance of Common
Shares, Preferred Shares, Depositary Shares, Trust Warrants, or other Trust
Securities or Partnership Debt Securities exchangeable or convertible into
common shares or preferred 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 Trust Securities, 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:

          1.  When and if (a) the terms, issuance, execution and delivery by the
Company of any of the Trust Debt Securities have been duly authorized by all
necessary action of the Company and as contemplated by either the Senior
Indenture or the Subordinated Indenture (as those terms are defined in the S-3
Registration Statement)(either of which shall be referred to herein as an
"Indenture"), and (b) those Trust Debt Securities have been duly executed and
delivered by the Company, authenticated by the trustee under the appropriate
Indenture and sold as contemplated by each of the S-3 Registration Statement,
the S-3 Prospectus, the applicable supplement or supplements to the S-3
Prospectus and the appropriate Indenture, assuming that the terms of those Trust
Debt Securities are in compliance with the applicable Indenture, those Trust
Debt Securities will be validly issued and will constitute valid and binding
obligations of the Company, enforceable against the Company in accordance with
