PART I

ITEM 1. BUSINESS
- ----------------

THE COMPANY

Liberty Property Trust (the "Trust") is a self-administered and self-
managed Maryland real estate investment trust (a "REIT"). Substantially
all of the Trust's assets are owned directly or indirectly, and
substantially all of the Trust's operations are conducted directly or
indirectly, by its subsidiary, Liberty Property Limited Partnership, a
Pennsylvania limited partnership (the "Operating Partnership" and,
together with the Trust and its consolidated subsidiaries, the
"Company"). The Company was formed to continue and expand the
commercial real estate business of Rouse & Associates, a Pennsylvania
general partnership, and certain affiliated entities (collectively, the
"Predecessor"). Founded in 1972, the Predecessor developed and managed
commercial real estate in the Southeastern, Mid-Atlantic and West Coast
markets.

The Company provides leasing, property management, acquisition,
development, construction management, design management and other
related services for a portfolio which, as of December 31, 1998,
consisted of 608 industrial and office properties (the "Properties in
Operation") totalling approximately 44.2 million leaseable square feet.
As of December 31, 1998, the Properties in Operation were approximately
95.0% leased to over 1,900 tenants. As of December 31, 1998, the
Company also had 45 properties under development (the "Properties Under
Development" and, together with the Properties in Operation, the
"Properties"). The Properties Under Development are expected to
generate, upon completion, approximately four million leaseable square
feet. The Properties are located principally within the Southeastern,
Mid-Atlantic and Midwestern United States. As of December 31, 1998, the
Company also owned 1,113 acres of land, all zoned for commercial use,
which the Company anticipates are capable of supporting, as and when
developed, approximately nine million leaseable square feet.

During the year ended December 31, 1998, through Total Investments (as
defined below) aggregating $863.6 million, the Company increased its
total leaseable square footage of industrial and office space
approximately 36.1% by acquiring 144 properties totalling approximately
8.6 million leaseable square feet and by developing 34 properties
totalling approximately 3.5 million leaseable square feet. The "Total
Investment" for a property is defined as the property's purchase price
plus closing costs and management's estimate, as determined at the time
of acquisition, of the cost of necessary building improvements in the
case of acquisitions, or land costs and land and building improvement
costs in the case of development projects, and, where appropriate, other
development costs and carrying costs required to reach rent
commencement.

The Properties in Operation, as of December 31, 1998, consisted of 424
industrial and 184 office properties. Single tenants occupied 241 of
the Properties in Operation. The remaining 367 of the Properties in
Operation are multiple tenant properties for which the Company renders a
range of building, operating and maintenance services.

The Company's industrial properties consist of a variety of warehouse,
distribution, service, assembly, light manufacturing and research and
development facilities. Substantially all of the Company's industrial

- -5-

properties are located in suburban, mixed-use developments or business
parks. They include both single-tenant and multi-tenant facilities,
with most designed flexibly to accommodate various types of tenants,
space requirements and industrial uses in an effort to increase re-
leasing opportunities and control re-leasing costs. The Company's
office properties are mid-rise and single-story office buildings,
located principally in suburban mixed-use developments or office parks.
Substantially all of the Company's properties are located in prime
business locations within established business communities offering
excellent access to interstate highway systems.

The Trust is the sole general partner and also a limited partner of the
Operating Partnership, with a combined equity interest in the Operating
Partnership of 92.6% at December 31, 1998. The units of limited
partnership interest in the Operating Partnership (the "Units") are
exchangeable on a one-for-one basis (subject to antidilution
protections) for the Common Shares of Beneficial Interest, $0.001 par
value per share (the "Common Shares"), of the Trust, typically after the
first anniversary of the issuance of any such Units. The only limited
partners of the Operating Partnership other than the Trust are persons
or entities that contributed assets to the Operating Partnership and
received Units in exchange therefor. The Units held by the limited
partners other than the Trust (that is, the minority interest reflected
in the Trust's financial statements) were exchangeable for approximately
5.2 million Common Shares on December 31, 1998. Certain holders of
Units issued in connection with the contribution of assets to the
Operating Partnership have the right to require the Company to register
the issuance or resale of the Common Shares underlying their Units upon
exchange for the Units, in order to afford such holders liquidity with
respect to their investment.

The Company's executive offices are located at 65 Valley Stream Parkway,
Malvern, Pennsylvania 19355. The telephone number is (610) 648-1700.
The Company maintains offices in each of its principal markets. As of
December 31, 1998 the Company's principal markets were as follows:
Southeastern Pennsylvania; New Jersey/Delaware; Lehigh Valley,
Pennsylvania; Maryland; Virginia; the Carolinas; Jacksonville, Florida;
Tampa, Florida; South Florida; Minneapolis, Minnesota; Detroit,
Michigan; and the United Kingdom. Additionally, the Company owns and
operates properties in the Orlando, Florida and Milwaukee, Wisconsin
markets. For further detail regarding the Company's properties in
particular markets, please refer to Item 2. Properties and Notes 11 and
10 of the Notes to the Liberty Property Trust and the Liberty Property
Limited Partnership Financial Statements, respectively.

MANAGEMENT AND EMPLOYEES

The Company's 331 employees (as of February 22, 1999) are under the
direction of 19 senior executives, who have developed and managed
commercial real estate during the past 26 years and who, on average,
have been affiliated with the Company and/or the Predecessor for 13
years. The Company's in-house leasing, marketing and property management
staff operates in full-service local offices in markets where it has a
significant presence. This structure enables the Company to better
understand the particular characteristics of the local markets in which
it operates, to respond quickly and directly to tenant needs and to
better identify local development and acquisition opportunities. The
Company considers its relations with its employees to be good.

BUSINESS OBJECTIVES AND STRATEGIES FOR GROWTH

The Company's business objective is to maximize long-term profitability
for its shareholders by (i) maintaining and increasing property
occupancy and rental rates through the effective management of the
Properties, and (ii) developing and acquiring high-quality properties.
In accomplishing these objectives the Company also intends to maintain a
conservative and flexible capital structure.

INTERNAL GROWTH STRATEGIES

Management believes that the Properties offer significant opportunities
for the Company to increase its rental revenues and cash flow over the
long term. The Company seeks to increase cash flow by continuing its
practice of negotiating for annual contractual rental increases that
take effect during the terms of its leases. In addition, the Company
seeks to increase rental revenues through the renewal or replacement of
expiring leases at rental rates which are higher than the rates under
expiring leases and by improving the occupancy rates of its portfolio.
Finally, the Company intends to maximize earnings through controlling
costs.

NEW LEASES AND LEASE RENEWALS. In the past year, the Company generally
has been experiencing increases in rental rates in replacement and
renewal leases. Although no assurance can be given, the Company expects
that in the near term, replacement and renewal leases will continue to
reflect rental rates which are higher than the rates under expiring
leases.

CONTRACTUAL INCREASES. The Company seeks to generate increased cash
flow from the Properties in Operation through annual contractual
increases in rental rates under its leases. The leases in effect with
respect to the Properties in Operation as of December 31, 1998 provide
for contractual rental increases that are expected to contribute an
additional $5.0 million to the Company's cash flow for the year ending
December 31, 1999. The Company intends to continue seeking to negotiate
annual contractual rent increases that take effect during the terms of
its leases.

MAINTAINING HIGH OCCUPANCIES. The Company believes that the quality and
diversity of its tenant base and its strategy of operating in multiple
markets has contributed, and will continue to contribute, to its success
in obtaining increases in rental rates and maintaining high occupancy
levels. The Company targets financially stable tenants in an effort to
minimize uncertainty relating to the ability of its tenants to meet
their lease obligations.

COST CONTROLS. The Company monitors and controls its operating and
administrative costs by performing many functions in-house rather than
by engaging outside third parties. For example, although construction
and design services typically are provided by third parties, the
Company's in-house construction and design management staff closely
supervises construction and design activities in an effort to control
costs, minimize cost overruns, ensure timely delivery of tenant space
and maximize productivity and efficiencies. The Company also employs an
annual capital improvement and preventive maintenance program designed
to reduce the operating costs of the Properties and maintain long-term
values.

- -7-


DEVELOPMENT

STRATEGY. The Company pursues selective development opportunities,
focusing primarily on high-quality suburban industrial and office
properties within its existing markets. The Company has developed over
38 million square feet of commercial real estate during the past 26
years. The Company's development activities fall into two categories:
build-to-suit projects and projects built for inventory. The Company
develops build-to-suit projects for existing and new tenants. The
buildings in these projects are substantially pre-leased to one or more
tenants prior to construction. The Company also builds properties for
inventory, typically in high-occupancy markets in which the Company has
identified sufficient demand at market rental rates to justify such
construction.

COMPLETED PROPERTY DEVELOPMENTS. During the year ended December 31,
1998, the Company completed 12 build-to-suit and 22 inventory
projects, totalling approximately 3.5 million square feet of leaseable
space and representing an aggregate Total Investment of approximately
$237.3 million. As of December 31, 1998, these completed development
properties were 94.5% leased.

PROPERTIES UNDER DEVELOPMENT. As of December 31, 1998, the Company had
45 Properties Under Development in 11 markets which, upon completion,
are expected to generate approximately four million leaseable square
feet. Approximately 56.8% of such leaseable space was pre-leased as of
December 31, 1998. The Properties Under Development as of December 31,
1998 are expected to represent a Total Investment of $367.8 million.
Six of these properties are 100% pre-leased under net leases as build-
to-suit projects. The Company is scheduled to complete development of 30
properties (totalling approximately 2.9 million leaseable square feet)
in the year ending December 31, 1999 representing a Total Investment of
$229.0 million.

ACQUISITIONS

STRATEGY

The Company seeks to acquire properties consistent with its business
objectives and strategies. The Company executes its acquisition
strategy by purchasing properties which management believes will create
shareholder value over the long term.

The Company has identified the following general categories of
properties for acquisition:

Stabilized Acquisitions - consist of properties which are typically
at high occupancy levels upon acquisition.

Entrepreneurial Acquisitions - consist of properties which are
typically either vacant or at low occupancy levels and can be purchased
substantially below replacement cost, thereby offering the opportunity
for above-average returns when fully renovated and leased.

During the year ended December 31, 1998, the Company acquired 144
properties comprising approximately 8.6 million leaseable square feet
for a Total Investment of $626.3 million. The following sets forth
certain information with respect to such acquisitions:

- -8-


Stabilized Acquisitions. During the year ended December 31, 1998
the Company completed stabilized acquisitions of 136 properties
aggregating approximately 8.2 million leaseable square feet of
industrial and office space for a Total Investment of $587.7 million.

Entrepreneurial Acquisitions. During the year ended December 31,
1998, the Company completed entrepreneurial acquisitions of eight
properties aggregating approximately 450,000 leaseable square feet of
industrial and office space for a Total Investment of $38.6 million.

LAND. As of December 31, 1997, the Company owned 957 acres of land for
development, all zoned for commercial use. During the year ended
December 31, 1998, the Company purchased an additional 472 acres of land
for development, utilized 259 acres in development projects and sold 57
acres. Substantially all of the remaining 1,113 acres owned as of
December 31, 1998 are located adjacent to or within existing industrial
or business parks with site improvements, such as public sewers, water
and utilities, available for service. The Company anticipates that the
land would support, as and when developed, approximately nine million
leaseable square feet. The Company's investment in land held for
development as of December 31, 1998 was $75.5 million. The Company is
obligated to purchase, over a 10-year period ending in 2007,
approximately 775 acres of land for commercial development for $16.2
million as of December 31, 1998. The Company believes the land will
support, as and when developed, approximately eight million leaseable
square feet of industrial or office space. This land is located in the
Charleston, Columbia and Greenville, South Carolina and Tampa, Florida
markets. The Company believes that, because it is a fully integrated
real estate firm, its base of commercially zoned land in existing
industrial and business parks provides a competitive advantage for
future development activities.

INTERNATIONAL OPERATION. The Company's international operation includes
five Properties in Operation in the County of Kent, England. In
addition, the Company provides management services with respect to a
joint venture between Rouse Kent Limited, which is owned by certain
senior executives of the Company, and the County of Kent, England to
develop a 650-acre, mixed-use park approximately 25 miles southeast of
London. The Company has an option to purchase Rouse Kent Limited for
nominal consideration. The Company has a loan receivable from Rouse
Kent Limited at December 31, 1998, with an outstanding balance of $5.9
million.

SUBSEQUENT ACTIVITIES

Since December 31, 1998, and through February 22, 1999, the Company has
completed development of seven industrial and office properties
containing approximately 415,000 leaseable square feet for a Total
Investment of $23.2 million. In addition, during such period the
Company has purchased seven industrial and office properties containing
approximately 275,000 leaseable square feet for a Total Investment of
$26.3 million.

On January 15, 1999 the Company closed a $135 million, two-year
unsecured term loan. The interest rate for the loan is 135 basis points
over LIBOR.

The Company intends to continue to pursue its development and
acquisition strategies. The Company is currently in various stages of
discussions and negotiations with respect to development and acquisition
projects with a Total Investment of approximately $150.0 million. The

- -9-

consummation of these or any other future developments or acquisitions,
if any, and the pace at which developments may be completed and
acquisitions made, cannot be assured.

COMPETITION

The Company faces competition as a lessor, buyer, and developer of
properties and will likely face competition as a seller of
properties to the extent that properties are sold. The Company believes
that its responsiveness to tenant needs will enable it to attract and
retain high quality tenants in the markets in which the Properties in
Operation are located. However, the number of competitive properties in
any particular market in which the Company's Properties are located
could have a material adverse effect on both the Company's ability to
lease space and on rental rates at the Properties. There are numerous
other entities, including but not limited to other REITs, that compete
with the Company in seeking to acquire the limited number of properties
available for sale that meet the Company's criteria. However, the
Company believes that its management, its capital base, its existing
sources of credit and its access to capital will provide the Company
with competitive advantages.

ENVIRONMENTAL REGULATIONS

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

All of the Properties and land have been subject to Phase I
Environmental Assessments ("Phase I Assessments"). The Phase I
Assessments did not reveal, nor is the Company aware of, any non-

- -10-

compliance with Environmental Laws, environmental liability or other
environmental claim that the Company believes would likely have a
material adverse effect on the Company. Although certain environmental
issues have been identified with respect to certain of the Properties,
the Company does not believe that any of these issues is likely to
materially adversely affect the results of the Company's operations. No
assurance can be given that the Phase I Assessments revealed all
potential environmental liabilities, that no prior owner or operator
created any material adverse environmental condition not known to the
Company, that no environmental liabilities have developed since such
Phase I Assessments were prepared, that future laws, ordinances or
regulations will not impose any material environmental requirement or
liability, or that a material adverse environmental condition does not
otherwise exist.

ITEM 2. PROPERTIES

The Properties in Operation, as of December 31, 1998, consisted of 424
industrial and 184 office properties.

Single tenants occupy 241 Properties in Operation. The Company provides
a reduced level of service in connection with the operation or
maintenance of these properties. The remaining 367 of the Company's
Properties in Operation are multiple tenant properties for which the
Company renders a range of building, operating and maintenance services.

The Company's industrial properties consist of a variety of warehouse,
distribution, service, assembly, light manufacturing, and research and
development facilities. Substantially all of the Company's industrial
properties are located in suburban, mixed-use developments or business
parks and all are well-maintained facilities. They include both single-
tenant and multi-tenant facilities, with most designed flexibly to
accommodate various types of tenants, space requirements, and industrial
uses to increase re-leasing opportunities and control re-leasing costs.
The average building size of the industrial properties is 75,094
leaseable square feet. As of December 31, 1998, the Company's
industrial properties were 94.8% leased. Major industrial tenants,
based upon annual base rent, include the Government of the United States
of America, DSC Logistics, Inc., Hewlett-Packard Company and General
Electric Company. None of the industrial tenants accounts for more than
2% of the Company's total annual base rent.

The Company's office properties are mid-rise and single story office
buildings principally located in suburban, mixed-use developments or
office parks. All of the Company's office properties are well-
maintained facilities. Substantially all are located in prime business
locations within established business communities offering excellent
access to interstate highway systems. As of December 31, 1998, the
office properties were approximately 95.6% leased. The average building
size of the office properties is 67,002 leaseable square feet. Major
office tenants, based upon annual base rent, include The Vanguard Group,
AT&T Resource Management, Corp., SmithKline Beecham, the Prudential
Insurance Company, PNC Bank and Sanofi Winthrop, Inc. None of the
office tenants accounts for more than 4% of the Company's total annual
base rent.

The table on the following pages sets forth certain information on the
Company's Properties in Operation as of December 31, 1998.

ITEM 3. LEGAL PROCEEDINGS

The Trust is not a party to any material legal proceedings. In the
ordinary course of business, the Operating Partnership is party to
routine litigation incidental to its business, including routine actions
for negligence, personal injury or other claims, many of which are
expected to be covered by liability insurance and in the aggregate are
not expected to have a material effect on the business or financial
condition of the Company.

On June 27, 1995, the Environmental Protection Agency ("EPA") notified
Willard G. Rouse III, and two former senior executives, together with
six other companies or individuals, that they may be potentially
responsible, as former owners, for a portion of the response costs for
remediation of ground water in part of the North Penn Service Area for
certain properties located in Upper Gwynedd Township, Pennsylvania, (the
"Church Road Properties"). The Company acquired the Church Road
Properties from the Predecessor upon formation of the Company. The
Company has not been similarly notified by the EPA; however, as the
present owner of the Church Road Properties, the potential exists for
the Company to be named a potentially responsible party if there has
been a release from the Church Road Properties of hazardous substances,
including trichloroethylene, that requires remediation. In such
circumstances, the Company believes it would have claims against other
financially responsible parties (including previous owners of the Church
Road Properties, such as Zenith and the other parties identified by the
EPA as potentially liable) and, consequently, the Company does not
believe that its liability with respect to this matter, if any, is
likely to be material. In addition, Mr. Rouse, Joseph P. Denny and two
former senior executives agreed to indemnify the Company for a period of
10 years commencing in June 1994 with respect to material environmental
liabilities associated with the Church Road Properties.

and uninterrupted dividends.

Although the Company currently anticipates that comparable cash
dividends will continue to be paid in the future, the payment of future
dividends by the Company will be at the discretion of the Board of
Trustees and will depend on numerous factors including the Company's

distribution requirements under the REIT provisions of the Internal
Revenue Code of 1986, as amended, and such other factors as the Board of
Trustees deems relevant.

Basic weighted average number of shares includes only Common

Diluted weighted average number of shares outstanding includes the
dilutive effect of outstanding options, and excludes Common Shares
issuable upon conversion of Units, and upon the exchange of Convertible
Debentures, because to do so would have been antidilutive for the
periods presented, with the exception of the period June 23, 1994 to
December 31, 1994. The diluted weighted average shares for this period
includes the dilutive effect of all of the aforementioned securities.

"Funds from operations" is defined by the National Association of
Real Estate Investment Trusts ("NAREIT") as net income or loss after
preferred dividends (computed in accordance with generally accepted
accounting principles ("GAAP")), excluding gains (or losses) from debt
restructuring and sales of property, plus real estate-related
depreciation and amortization and minority interest, and excluding
significant non-recurring events that materially distort the comparative
measurement of Company performance over time. Funds from operations
does not represent cash generated from operating activities in
accordance with GAAP and is not necessarily indicative of cash available
to fund cash needs.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

OVERVIEW

The following discussion and analysis is based on a consolidated view of
the Company. Geographic segment data for the years ended December 31,
1998, 1997 and 1996 is included in Notes 11 and 10 of the Notes to the
Liberty Property Trust and the Liberty Property Limited Partnership Financial
Statements, respectively.

In 1998, the Company continued to pursue development and acquisition
opportunities and continued to focus on increasing the cash flow from
its Properties in Operation by increasing property occupancy and
increasing rental rates. The Company also continued to strengthen its
balance sheet and its capital structure.

The Company's operating results depend primarily upon income from the
rental operations of the Properties in Operation. This income is
substantially influenced by the demand for the Properties in Operation.

- -23-


In addition, the Company's continued growth is dependent upon its
ability to maintain property occupancy rates and increase rental rates
on the Properties in Operation and to continue the development and
acquisition of additional properties. The occupancy rate of the
Properties in Operation has increased during each of the last three
years and was 95.0% at December 31, 1998. The Company will seek to
maintain and increase its overall occupancy and also will seek to
increase rental rates in replacement and renewal leases. Stable or
increased occupancy, along with increasing rental rates, would allow the
Properties in Operation to continue to provide a comparable or
increasing level of income from rental operations.
The Company also will seek to achieve growth in income from rental
operations through (i) growth of its core portfolio by maintaining high
levels of occupancies and obtaining increases in rental rates upon
expirations of leases, (ii) the maintenance and expansion of its
development pipeline, (iii) the acquisition of additional rental
properties where the Company has identified opportunities to add value,
and (iv) selected disposition of properties.

The Company increased its level of development activity in 1998. The
Company completed development of 34 properties totalling approximately
3.5 million leaseable square feet for a Total Investment of $237.3
million. In 1997, the Company completed development of 20 properties
totalling approximately 2.9 million leaseable square feet for a Total
Investment of $143.5 million. In addition, as of December 31, 1998, the
Company had 45 Properties Under Development expected to generate, upon
completion, approximately four million leaseable square feet of suburban
office and industrial space for a Total Investment of approximately
$367.8 million. The Company expects to complete the Properties Under
Development over the next eight quarters.

The Company acquired 144 properties consisting of approximately 8.6
million leaseable square feet during 1998 as compared to the acquisition
of 170 properties consisting of approximately 9.5 million leaseable
square feet during 1997. The Company will seek, through its active
pursuit of acquisitions in its multiple markets, to continue to achieve
attractive returns on acquisitions. However, the Company anticipates
that given current market conditions, that the pace of acquisitions of
rental properties in 1999 will be slower than in 1998.

In 1998, the Company disposed of ten properties totalling approximately
412,000 leaseable square feet for $18.9 million. In 1997, the Company
disposed of eight properties totalling approximately 635,000 leaseable
square feet for $35.4 million. The Company anticipates the selective
disposition of properties to continue as strategic opportunities arise.

The Company continued to strengthen its balance sheet in 1998 by
accessing both the public and private equity markets and the public debt
market. The Company raised approximately $296.3 million through the
issuance of Common Shares. In addition, over the course of the year,
the Company issued $295.0 million of investment grade rated unsecured
notes with maturities ranging from 4 to 15 years.

FORWARD-LOOKING STATEMENTS

When used throughout this report, the words "believes," "anticipates,"
and "expects" and similar expressions are intended to identify forward-
looking statements. Such statements indicate that assumptions have been
used that are subject to a number of risks and uncertainties which could
cause actual financial results or management plans and objectives to
differ materially from those projected or expressed herein, including:

- -25-

the effect of national and regional economic conditions; the Company's
ability to identify and secure additional properties and sites that meet
its criteria for acquisition or development; the availability of
capital; and the effect of prevailing market interest rates; and other
risks described from time to time in the Company's filings with the
Securities and Exchange Commission. Given these uncertainties, readers
are cautioned not to place undue reliance on such statements. The
Company undertakes no obligation to update statements that may be made
to reflect any future events or circumstances.

RESULTS OF OPERATIONS

The following discussion is based on the consolidated financial
statements of the Company. It compares the results of operations of the
Company for the year ended December 31, 1998 with the results of
operations of the Company for the year ended December 31, 1997, and the
results of operations of the Company for the year ended December 31,
1997 with the results of operations of the Company for the year ended
December 31, 1996. As a result of the significant level of acquisition
and development activities by the Company in 1998 and 1997, the overall
operating results of the Company during such periods are not directly
comparable. However, certain data, including the "Same Store"
comparison, do lend themselves to direct comparison.

This information should be read in conjunction with the accompanying
consolidated financial statements and notes included elsewhere in this
report.

COMPARISON OF YEAR ENDED DECEMBER 31, 1998 TO YEAR ENDED DECEMBER 31,
1997.

Total revenue (principally rental revenue and operating expense
reimbursement) increased to $387.1 million for the year ended December
31, 1998 from $232.5 million for the year ended December 31, 1997. This
increase was primarily due to the increase in the number of Properties
in Operation owned during the respective periods. As of January 1, 1997,
the Company owned 259 properties and, through December 31, 1997,
acquired 170 additional properties and completed development on 20
properties for a Total Investment (as defined below) of $871.5 million
and disposed of eight properties for $35.4 million. As of January 1,
1998, the Company owned 441 properties, and, through December 31, 1998,
acquired 144 additional properties and completed the development on 34
properties for a Total Investment of $863.6 million, and disposed 10
properties for $18.9 million. Furthermore, total revenue increased
because the operating expense recovery percentage (the ratio of
operating expense reimbursement to rental property expenses and real
estate taxes) increased to 93.4% for the year ended December 31, 1998
from 90.9% for the year ended December 31, 1997 due to the increase in
occupancy. The "Total Investment" for a property is defined as the
property's purchase price plus closing costs and management's estimate,
as determined at the time of acquisition, of the cost of necessary
building improvements in the case of acquisitions, or land costs and
land and building improvement costs in the case of development projects,
and where appropriate, other development costs and carrying costs
required to reach rent commencement.

Rental property and real estate tax expenses increased to $108.3 million
for the year ended December 31, 1998 from $61.1 million for the year
ended December 31, 1997. This increase is due to the increase in the
number of properties owned.

- -26-


Property level operating income for the "Same Store" properties
(properties owned since January 1, 1997) increased to $129.7 million for
the year ended December 31, 1998 from $124.2 million for the year ended
December 31, 1997, with straightlining (which recognizes rental revenue
evenly over the life of the lease), and increased to $129.3 million for
the year ended December 31, 1998 from $122.8 million for the year ended
December 31, 1997, without straightlining. These increases of 4.4%, and
5.3%, respectively are due to increases in rental rates and increases in
occupancy.

Set forth below is a schedule comparing the property level operating
income, with and without straightlining, for the Same Store properties
for the years ended December 31, 1998 and 1997.

======== ======== ======== ========


General and administrative expenses increased to $15.5 million for the
year ended December 31, 1998 from $10.7 million for the year ended
December 31, 1997. This $4.8 million increase is due to the increase in
personnel and other related overhead costs necessitated by the increase
in the number of properties owned during the respective periods. The
increase is somewhat mitigated by the benefit of certain economies of
scale experienced by the Company in owning and operating the increased
number of properties. Additionally, the year ended December 31, 1998
reflects the expensing of internal acquisition costs as of January 1,
1998 in compliance with EITF 97-11, whereas these costs of $1.2 million
were capitalized in 1997.

Depreciation and amortization expenses increased to $67.9 million for
the year ended December 31, 1998 from $40.8 million for the year ended
December 31, 1997. This increase is due to the increase in the number
of properties owned during the respective periods.

Interest expense increased to $78.6 million for the year ended December
31, 1998 from $53.9 million for the year ended December 31, 1997. This
increase is due to an increase in the average debt outstanding for the
respective periods which was $1,233.3 million in 1998 and $787.7 million
in 1997. This increase is also due to an increase in the weighted
average interest rates for the periods, to 7.5% in 1998 from 7.3% in
1997.

As a result of the foregoing, the Company's operating income increased
to $195.3 million for the year ended December 31, 1998 from $120.0
million for the year ended December 31, 1997. In addition, income
before minority interest increased to $116.7 million for the year ended

December 31, 1998 from $66.1 million for the year ended December 31,
1997.

COMPARISON OF YEAR ENDED DECEMBER 31, 1997 TO YEAR ENDED DECEMBER 31,
1996.

Total revenue (principally rental revenue and operating expense
reimbursement) increased to $232.5 million for the year ended December
31, 1997 from $154.3 million for the year ended December 31, 1996. This
increase was primarily due to the increase in the number of properties
owned during the respective periods. As of January 1, 1996, the Company
owned 208 properties and, through December 31, 1996, acquired 33
additional properties and completed development on 19 properties for a
Total Investment of $232.2 million. As of January 1, 1997, the Company
owned 259 properties, and, through December 31, 1997, acquired 170
additional properties and completed the development on 20 properties for
a Total Investment of $871.5 million, and disposed of eight properties
for $35.4 million. Furthermore, total revenue increased because the
operating expense recovery percentage (the ratio of operating expense
reimbursement to rental property expenses and real estate taxes)
increased to 90.9% for the year ended December 31, 1997 from 87.8% for
the year ended December 31, 1996 due to the increase in occupancy.

Rental property and real estate tax expenses increased to $61.1 million
for the year ended December 31, 1997 from $40.9 million for the year
ended December 31, 1996. This increase is due to the increase in the
number of properties owned.

Property level operating income for the "Same Store" properties
(properties owned since January 1, 1996) increased to $98.8 million for
the year ended December 31, 1997 from $94.1 million for the year ended
December 31, 1996, with straightlining (which recognizes rental revenue
evenly over the life the lease), and increased to $98.3 million for the
year ended December 31, 1997 from $93.0 million for the year ended
December 31, 1996, without straightlining. These increases of 5.0%, and
5.7%, respectively are due to increases in rental rates and increases in
occupancy.

Set forth below is a schedule comparing the property level operating
income, with and without straightlining, for the Same Store properties
for the years ended December 31, 1997 and 1996.

General and administrative expenses increased to $10.7 million for the
year ended December 31, 1997 from $8.0 million for the year ended

- -28-

December 31, 1996. This $2.7 million increase is due to the increase in
personnel and other related overhead costs necessitated by the increase
in the number of properties owned during the respective periods. This
increase is somewhat mitigated by the benefit of certain economies of
scale experienced by the Company in owning and operating the Properties.

Depreciation and amortization expenses increased to $40.8 million for
the year ended December 31, 1997 from $28.2 million for the year ended
December 31, 1996. This increase is due to the increase in the number
of properties owned during the respective periods.

Interest expense increased to $53.9 million for the year ended December
31, 1997 from $38.5 million for the year ended December 31, 1996. This
increase is due to an increase in the average debt outstanding for the
respective periods which was $552.4 million in 1996 and $787.7 million
in 1997. This increase is partly offset by the lower interest rates on
the outstanding debt. The reduction in interest rates was partially the
result of the Company receiving investment grade ratings from both
Standard & Poor's Ratings Group ("S&P") and Moody's Investors Service,
Inc. ("Moody's") during the year which enabled the Company to access
public debt markets more economically.

As a result of the foregoing, the Company's operating income increased
to $120.0 million for the year ended December 31, 1997 from $77.2
million for the year ended December 31, 1996. In addition, income
before minority interest increased to $66.1 million for the year ended
December 31, 1997 from $37.6 million for the year ended December 31,
1996.

LIQUIDITY AND CAPITAL RESOURCES

As of December 31, 1998, the Company had cash and cash equivalents of
$14.4 million.

Net cash flow provided by operating activities increased to $219.2
million for the year ended December 31, 1998 from $136.6 million for the
year ended December 31, 1997. This $82.6 million increase was primarily
due to the additional cash flow generated by the greater number of
properties in service during the latter period as discussed above under
"Results of Operations". Net cash flow provided by operations is the
primary source of liquidity to fund distributions to shareholders and
for the recurring capital expenditures and re-leasing costs for the
Company's properties.

Net cash used in investing activities decreased to $839.5 million for
the year ended December 31, 1998 from $864.6 million for the year ended
December 31, 1997. This $25.1 million decrease was a result of the
decrease in net investment in Operating Properties partially offset by
an increase in investment in development and land held for development.

Net cash provided by financing activities decreased by $183.8 million to
$579.6 million for the year ended December 31, 1998 from $763.4 million
for the year ended December 31, 1997. Net cash provided by financing
activities includes proceeds from the issuance of equity and debt net of
debt repayments and shareholder distributions. It is the Company's
primary source of capital to fund its investment activities. Although
the Company's level of investment activities was relatively constant
between 1997 and 1998, the Company decreased its financing activities
because of additional cash flow provided by operations in 1998 and
because it utilized $40.7 million of its cash balance during 1998.

- -29-


The Company believes that its undistributed cash flow from operations is
adequate to fund its short-term liquidity requirements.

The Company funds its acquisitions and completed development with long-
term capital sources. These activities may be funded on a temporary
basis through its $325.0 million unsecured line of credit (the "Credit
Facility"), which matures May, 1999, and can be extended for one year
for $650,000.

The interest rate on borrowings under the Credit Facility fluctuates
based upon the Company's leverage levels or ratings from Moody's and
S&P. On June 23, 1997, Moody's raised its prospective senior debt rating
of the Company to Baa3 from Ba2 and on July 22, 1997, S&P assigned a
BBB- prospective senior debt rating to the Company. At these ratings,
the interest rate for borrowings under the Credit Facility is 110 basis
points over LIBOR.

As of December 31, 1998, $413.2 million in mortgage loans and $645.0
million in unsecured notes were outstanding. The interest rates on
$1,041.6 million of mortgage loans and unsecured notes are fixed and
range from 5.0% to 9.1%. Interest rates on $16.6 million of mortgage
loans float with LIBOR, prime or a municipal bond index, $10.0 million
of which is subject to certain caps. The weighted average remaining
term for the mortgage loans and unsecured notes is 8.5 years. The
scheduled maturities of principal amortization of the Company's mortgage
loans and unsecured notes outstanding and the related weighted average
interest rates are as follows:

GENERAL

The Company believes that its existing sources of capital will provide
sufficient funds to finance its continued development and acquisition
activities. The Company's need for capital in 1998 was somewhat reduced
by a decline in acquisition activity, resulting from a general
marketplace decline during that period in initial returns on
acquisitions. The Company's existing sources of capital include the
public debt and equity markets, proceeds from property dispositions and
net cash provided from its operating activities. Additionally, the
Company expects to incur variable rate debt, including borrowings under
the Credit Facility, from time to time.

In 1998, the Company received $296.3 million in aggregate net proceeds
from the issuance of Common Shares and $292.1 million in aggregate net
proceeds from the issuance of unsecured notes. The Company used the
aggregate net proceeds from the sale of Common Shares and the unsecured
notes to fund the Company's activities, including paying down the Credit
Facility, which funds acquisition and development activity.

In 1997, the Company received $433.9 million in aggregate net proceeds
from the issuance of Common Shares; $120.8 million in aggregate net
proceeds from the issuance of preferred shares and $347.0 million in
aggregate net proceeds from the issuance of unsecured notes. The
Company used the aggregate net proceeds from issuance of the Common
Shares, the preferred shares and unsecured notes to fund the Company's
activities, including paying down the Credit Facility, which funds
acquisition and development activity.

In connection with the acquisition of properties during the years ended
December 31, 1998 and 1997, the Company issued 1,049,846 and 1,197,739
Units, respectively.

The Company has an effective S-3 shelf registration statement on file
with the Securities and Exchange Commission (the "Shelf Registration
Statement"). As of March 1, 1999, pursuant to the Shelf Registration
Statement, the Trust has the capacity to issue up to $696.4 million in
equity securities and the Operating Partnership has the capacity to
issue up to $356.1 million in debt securities.

CALCULATION OF FUNDS FROM OPERATIONS

Management generally considers Funds from operations (as defined below)
a useful financial performance measure of the operating performance of
an equity REIT, because, together with net income and cash flows, Funds
from operations provides investors with an additional basis to evaluate
the ability of a REIT to incur and service debt and to fund acquisitions
and capital expenditures. Funds from operations is defined by NAREIT as
net income or loss after preferred dividends (computed in accordance
with generally accepted accounting principals ("GAAP")), excluding gains
(or losses) from debt restructuring and sales of property, plus real-
estate related depreciation and amortization and minority interest and
excluding significant non-recurring events that materially distort the
comparative measurement of the Company's performance over time. Funds
from operations does not represent net income or cash flows from
operations as defined by GAAP and does not necessarily indicate that
cash flows will be sufficient to fund cash needs. It should not be
considered as an alternative to net income as an indicator of the
Company's operating performance or to cash flows as a measure of
liquidity. Funds from operations also does not represent cash flows
generated from operating, investing or financing activities as defined

by GAAP. Funds from operations for the years ended December 31, 1998,
1997, and 1996 are as follows:

YEAR 2000 READINESS DISCLOSURE

Background

In the past, many computer software programs were written using two
digits rather than four to define the applicable year. As a result,
date-sensitive computer software may recognize a date using "00" as the
year 1900 rather than the year 2000. This is generally referred to as
the Year 2000 issue. If this situation occurs, the potential exists for
computer system failures or miscalculations by computer programs, which
could disrupt operations.

Approach

The Company has established a group to coordinate the Company's response
to the Year 2000 issue. This group, which reports to the President and
Chief Operating Officer, includes the Company's MIS Director, a Vice-
President-Property Management and its General Counsel, as well as
support staff. The Company is in the process of implementing a Year
2000 compliance program at the Company's offices and properties
consisting of the following phases:

PHASE 1 Compilation of an inventory of information technology
(IT) and non-IT systems that may be sensitive to the Year 2000 problem.

PHASE 2 Identification and prioritization of the critical systems
from the systems inventory compiled in Phase 1 and inquiries of third
parties with whom the Company does significant business (i.e., vendors,
service providers and tenants) as to the state of their Year 2000
readiness.

PHASE 3 Analysis of critical systems to determine which systems
are not Year 2000 compliant and evaluation of the costs to repair or
replace those systems.

PHASE 4 Repair or replace noncompliant systems and testing of
critical systems.

- -32-


Status

The Company's property management and accounting system uses four digit
year fields and consequently is believed to be Year 2000 compliant.

Phases 1, 2 and 3 are substantially complete but for the process of
following up on inquiries of significant third parties as to their Year
2000 readiness, which is currently ongoing.

Phase 4 is ongoing and will continue through the first half of calendar
1999. It is the Company's goal to have this project completed by
mid-1999. Based upon the analysis conducted to date, the Company
believes the major critical systems at the Company's properties are
currently compliant or will be compliant by mid-1999.

Costs

The total cost to the Company of making its systems Year 2000 compliant
is currently estimated to be in the range of $200,000-$300,000. The
majority of this cost relates to repairing certain software, testing
systems and retrofiting or replacing energy management systems at
certain of the properties. The cost for the replacement of the
equipment and the software will be capitalized and depreciated over
their expected useful life. To the extent existing hardware or software
is replaced, the Company will write-off the cost incurred. This write-
off is included in the above cost estimate. Furthermore, all costs
related to software modification, as well as all costs associated with
the Company's administration of its Year 2000 project, are being
expensed as incurred and are likewise included in the cost estimate
above.

Risks Associated with the Year 2000 Problem

The Company utilizes computer systems in many aspects of its business.
As noted, the Company's property management and accounting systems use
four digit year fields and are believed to be Year 2000 compliant.
Additionally, with respect to the hardware and software systems utilized
by the Company in its management information systems, the Company's
assessment to date indicates that these systems are Year 2000 compliant
or can readily be made Year 2000 compliant on a stand-alone basis.
Testing of this preliminary assessment and of the operation of these
systems together is ongoing.

The Company also utilizes microprocessors which are imbedded in systems
which are part of the building operations (e.g., microprocessors
contained within the buildings' energy management systems or fire and
life safety systems.) In particular, Year 2000 Problems in the HVAC,
security or other such systems at the properties could disrupt
operations at the affected properties. The Properties generally consist
of suburban office and industrial Properties. The Properties are also
principally single-story and low-rise buildings. The Company has
reviewed its building operating systems on a building by building basis.
At this point, based on the status of its assessment the Company does
not believe a material number of these systems are non-compliant.
Additionally, many of these systems, which operate automatically, can be
operated manually and consequently in the event these systems experience
a failure as a result of the Year 2000 problem, the disruption caused by
such failure should not be material to the Company's operations.

The Company is also exposed to the risk that one or more of its vendors
or service providers could experience Year 2000 problems that impact the

- -33-

ability of such vendor or service provider to provide goods and
services. Though this is not considered as significant a risk with
respect to the suppliers of goods, due to the availability of
alternative suppliers, the disruption of certain services, such as
utilities, could, depending upon the extent of the disruption, have a
material adverse impact on the Company's operations. To date, the
Company is not aware of any vendor or service provider Year 2000 issue
that management believes would have a material adverse impact on the
Company's operations. However, the Company has no means of ensuring
that its vendors or service providers will be Year 2000 ready. The
inability of vendors or service providers to complete their Year 2000
resolution process in a timely fashion could have a adverse impact on
the Company. The effect of non-compliance by vendors or service
providers is not determinable at this time.

In addition, the Company is exposed to the risk that one or more of its
tenants could experience Year 2000 problems that impact the ability of
such tenant to pay its rent to the Company in a timely fashion. The
Company does not believe that such a problem is likely to affect enough
tenants to pose a material problem for the Company. To date, the
Company is not aware of any tenant Year 2000 issue that would have a
material adverse impact on the Company's operations. However, the
Company has no means of ensuring that their tenants will be Year 2000
ready. The inability of tenants to complete their Year 2000 resolution
process in a timely fashion could have an adverse impact on the Company.
The effect of non-compliance by tenants is not determinable at this
time.

Widespread disruptions in the national or international economy,
including disruptions affecting the financial markets, resulting from
Year 2000 issues, or in certain industries, such as commercial or
investment banks, could also have an adverse impact on the Company. The
likelihood and effect of such disruptions is not determinable at this
time.

Readers are cautioned that forward-looking statements contained in the
Year 2000 discussion should be read in conjunction with the Company's
disclosures regarding forward-looking statements previously disclosed.

INFLATION

Inflation has remained relatively low during the last three years, and
as a result, has not had a significant impact on the Company during this
period. The Credit Facility and certain other indebtedness bear
interest at a variable rate; therefore, the amount of interest payable
under the Credit Facility and such other indebtedness will be influenced
by changes in short-term interest rates, which tend to be sensitive to
inflation. To the extent an increase in inflation would result in
increased operating costs, such as in insurance, real estate taxes or
utilities, substantially all of the tenant's leases require the tenants
to absorb these costs as part of their rental obligations. In addition,
inflation also may have the effect of increasing market rental rates.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
- --------------------------------------------------------------------

The following discussion about the Company's risk management includes
forward-looking statements that involve risks and uncertainties. Actual
results could differ materially from the results discussed in the
forward-looking statements.

- -34-


The Company's primary market risk exposure is to changes in interest
rates.

The Company is exposed to market risk related to its Credit Facility and
certain other indebtedness as discussed in "Management's Discussion and
Analysis of Financial Condition and Results of Operation - Liquidity and
Capital Resources and Inflation". The interest on the Credit Facility
and such other indebtedness is subject to fluctuations in the market.

The Company also uses long-term and medium-term debt as a source of
capital. These debt instruments are typically issued at fixed interest
rates. When these debt instruments mature, the Company typically
refinances such debt at then-existing market interest rates which may be
more or less than the interest rates on the maturing debt. In addition,
the Company may attempt to reduce interest rate risk associated with a
forecasted issuance of new debt. In order to reduce interest rate risk
associated with these transactions, the Company occasionally enters into
interest rate protection agreements.

If the interest rate for variable rate debt was 100 basis points higher
or lower during 1998, the Company's interest expense net of amounts
capitalized would have been increased or decreased by approximately $1.5
million. If interest rates for fixed rate debt maturing and to be
refinanced in 1999 is 100 basis points higher or lower than its current
weighted average rate of 6.3%, the Company's interest expense would be
increased or decreased by approximately $75,000.

Due to the uncertainty of fluctuations in interest rates, the specific
actions that might be taken by management to mitigate the impact of such
fluctuations and their possible effects, the sensitivity analysis
assumes no changes in the Company's financial structure.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA
- -----------------------------------------------------

The dual presentation of financial statements for the Company is
required by the Securities and Exchange Commission. The Company is
comprised of two Securities and Exchange Commission registrants: Liberty
Property Trust and Liberty Property Limited Partnership. Accordingly,
one set of financial statements are required for each registrant. The
financial information contained within the two sets of financial
statements is essentially the same, with the exception of reformatting
to account for the ownership differences between the entities.

REPORT OF INDEPENDENT AUDITORS




To The Board of Trustees and Shareholders
Liberty Property Trust



We have audited the accompanying consolidated balance sheets of Liberty
Property Trust (the "Trust") as of December 31, 1998 and 1997, and the
related consolidated statements of operations, shareholders' equity, and
cash flows for each of the three years in the period ended December 31,
1998. Our audits also included the financial statement schedule listed
in the Index at Item 14(a). These financial statements and schedule are
the responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and schedule based on
our audits.

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

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial
position of Liberty Property Trust at December 31, 1998 and 1997, and
the consolidated results of its operations and its cash flows for each
of the three years in the period ended December 31, 1998 in conformity
with generally accepted accounting principles. Also, in our opinion,
the related financial statement schedule, when considered in relation to
the basic financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS OF LIBERTY PROPERTY TRUST

1. ORGANIZATION

Liberty Property Trust (the "Trust") is a self-administered and self-
managed Maryland real estate investment trust (a "REIT"). Substantially
all of the Trust's assets are owned directly or indirectly, and
substantially all of the Trust's operations are conducted directly or
indirectly, by its subsidiary, Liberty Property Limited Partnership, a
Pennsylvania limited partnership (the "Operating Partnership" and,
together with the Trust and its consolidated subsidiaries, the
"Company"). The Trust is the sole general partner and also a limited
partner of the Operating Partnership, with a combined equity interest in
the Operating Partnership of 92.6% at December 31, 1998. The Company
provides leasing, property management, acquisition, development,
construction management, and design management for a portfolio of
industrial and office properties which are located principally within
the Southeastern, Mid-Atlantic and Midwestern United States.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

Principles of Consolidation

The Consolidated Financial Statements of the Company include the
accounts of the Trust, the Operating Partnership and the Operating
Partnership's consolidated subsidiaries. All significant intercompany
transactions and accounts have been eliminated.

Certain amounts from prior periods have been restated to conform to
current year presentation.

Real Estate and Depreciation

The Properties are recorded at the lower of cost or fair value if
impaired and are depreciated using the straight-line method over their
estimated useful lives. The estimated useful lives are as follows:

Building and improvements 40 years
Equipment 10 years
Tenant improvements Term of the related lease

Expenditures directly related to acquisition, development or improvement
of real estate are capitalized as a cost of the property. Expenditures
for maintenance and repairs are charged to operations as incurred.

The Company evaluates its real estate investments upon occurrence of
significant adverse changes in their operations to assess whether any
impairment indications are present that affect the recovery of the
recorded value. If any real estate investment is considered impaired, a
loss is provided to reduce the carrying value of the property to its
estimated fair value.

- -42-


Cash and Cash Equivalents

Highly liquid investments with a maturity of three months or less when
purchased are classified as cash equivalents. The carrying amount of
these assets approximates their fair market value.

Revenues

The Company earns rental income under operating leases with tenants.
Rental income is recognized on a straight-line basis over the applicable
lease term.

Deferred Financing and Leasing Costs

Costs incurred in connection with financing or leasing are capitalized
and amortized over the term of the related loan or lease. Amortization
of deferred financing costs is reported as interest expense.

Income per Common Share

The following table sets forth the computation of basic and diluted
income per common share:

- -43-


Diluted income per common share includes the weighted average common
shares and dilutive effect of the outstanding options, and excludes the
effects of the conversion of the Units and Convertible Debentures into
common shares, as to do so would have been antidilutive for the periods
presented. The securities excluded from the diluted calculation could
potentially dilute basic income per common share in the future.

Basic income per common share would be $1.60 calculated as if the
debenture conversions which occurred in 1998 had occurred on January 1,
1998.

Income Taxes

The Company has elected to be taxed as a REIT under Section 856 through
860 of the Internal Revenue Code of 1986, as amended (the "Code"). As a
result, the Company generally is not subject to federal income taxation
at the corporate level to the extent it distributes annually at least
95% of its REIT taxable income, as defined in the Code, to its
shareholders and satisfies certain other requirements. The Company has
met these requirements, and accordingly, no provision has been made for
federal income taxes in the accompanying consolidated financial
statements.

The Company and certain of its subsidiaries are subject to certain state
and local income, excise and franchise taxes. The provision for such
state and local taxes has been reflected in general and administrative
expense in the consolidated statements of operations and has not been
separately stated since it is not material.

The Federal tax cost basis of the real estate at December 31, 1998 was
approximately $2.9 billion.

Impact of Recently Issued Accounting Standards

In June 1998, the FASB issued Statement No. 133, "Accounting for
Derivative Instruments and Hedging Activities". The Company expects to
adopt the new Statement effective January 1, 2000. The Statement will
require the Company to recognize all derivatives on the balance sheet at
fair value. The Company does not anticipate that the adoption of this
statement will have a significant effect on its results of operations or
financial position.

3. REAL ESTATE

At December 31, 1998 and 1997, the Company owned and operated industrial
and office properties located principally in suburban mixed use

and $25.0 million in 1996.

As of December 31, 1998, the Company has commenced development on 45
properties in 11 markets, which upon completion are expected to comprise
approximately four million square feet of leaseable space. As of
December 31, 1998, approximately $207.6 million has been expended for
the development of these projects and an additional $160.2 million is
required for completion.

4. RELATED PARTY TRANSACTIONS

Pursuant to agreements, the Company has been retained by an affiliate
(Rouse Kent Limited) to provide development, management and other
services. For the years ended December 31, 1998, 1997 and 1996
the fees for these services were $600,000 per year. The Company has a
loan receivable from to Rouse Kent Limited with a balance of $5.9
million and $5.5 million as of December 31, 1998 and 1997, respectively.

5. INDEBTEDNESS

Indebtedness consists generally of mortgage loans, unsecured notes, the
credit facility, and convertible debentures. The weighted average
interest rates as of December 31, 1998, 1997 and 1996, were
approximately 7.2%, 7.5% and 7.6%, respectively. Interest expense for
the years ended December 31, 1998, 1997 and 1996, aggregated $78.6
million, $53.9 million and $38.5 million, respectively. Interest costs
during these periods of $16.3 million, $11.8 million and $7.7 million,
were capitalized. Cash paid for interest for the years ended December
31, 1998, 1997 and 1996, was $83.2 million, $54.9 million and $43.7
million, respectively.

Mortgage Loans, Unsecured Notes

Mortgage loans with maturities ranging from 1999 to 2013 are
collateralized by and in some instances cross-collateralized by
properties with a book value of $602.6 million.

- -45-


As of December 31, 1998, $413.2 million in mortgage loans and $645.0
million in unsecured notes were outstanding. The interest rates on
$1,041.6 million of mortgage loans and unsecured notes are fixed and
range from 5.0% to 9.1%. Interest rates on $16.6 million of mortgage
loans float with LIBOR, prime or a municipal bond index, $10.0 million
of which is subject to certain caps. The weighted average remaining
term for the mortgage loans and unsecured notes is 8.5 years. The
scheduled maturities of principal amortization of the Company's mortgage
loans and unsecured notes outstanding and the related weighted average
interest rates are as follows:

Credit Facility

The credit facility is a $325 million unsecured credit facility (the
"Credit Facility") which replaced two existing secured lines of credit
aggregating $350 million in May 1997. Coincident with the replacement
of the lines of credit, $2.9 million of related deferred financing costs
were charged to interest expense. The interest rate on borrowings under
the Credit Facility fluctuates, based on the Company's leverage levels
and senior debt ratings from Moody's Investors Service, Inc. ("Moody's")
and Standard & Poor's Ratings Group ("Standard & Poor's"). The current
ratings for the Company's senior unsecured debt are Baa3 and BBB- from
Moody's and Standard & Poor's, respectively. At these ratings, the
current interest rate on the Credit Facility is 110 basis points over
the LIBOR Rate (6.67% at December 31, 1998). The rate for the Credit
Facility at December 31, 1997 was 7.09%. Customary fees apply to the
Credit Facility including an annual administrative fee and an unused
line fee. The Credit Facility matures on May 20, 1999, and can be
extended for one year for $650,000.

On January 15, 1999 the Company closed a $135 million, two-year
unsecured term loan. The interest rate for the loan is 135 basis points
over LIBOR.

- -46-


Convertible Debentures

The convertible debentures are due on June 23, 2001 and are exchangeable
for common shares of beneficial interest of the Trust (the "Common
Shares") at a rate of one Common Share for each $20 outstanding
principal amount of convertible debentures, subject to certain
adjustments. The initial interest rate on the convertible debentures
was 8.0% and increases with increases in the dividend payment on the
Company's Common Shares. At the current $.45 per common share per
quarter dividend payment rate, the effective interest rate on the
convertible debentures is 9.0%. At December 31, 1997, the effective
interest rate on the convertible debentures was 8.4%. During the year
ended December 31, 1997, the Company paid sums aggregating $98,000 to
facilitate the conversion of $17.3 million of convertible debentures
into 862,650 Common Shares. There was no such expense in 1998. At
December 31, 1998 and 1997 the convertible debentures were convertible
into 5,080,950 and 5,577,150 Common Shares, respectively.

The fair value of the convertible debentures at December 31, 1998 was
$125.1 million based on the closing bid price of the Company's Common
Shares on the New York Stock Exchange. The fair values of the
mortgages, the unsecured notes and Credit Facility were estimated using
discounted cash flow analysis, based on the Company's estimated
incremental borrowing rate at December 31, 1998, for similar types of
borrowing arrangements. The carrying values of the mortgages, the
unsecured notes and the Credit Facility approximate their fair values.

6. LEASING ACTIVITY

Future minimum rental payments due from tenants under non-cancellable
operating leases as of December 31, 1998 are as follows (in thousands):

1999 $ 306,662
2000 267,891
2001 218,764
2002 180,641
2003 144,407
Thereafter 508,082
----------
TOTAL $1,626,447
==========

In addition to minimum rental payments, tenants pay for their pro rata
share of specified operating expenses. These amounts are included as
operating expense reimbursement in the accompanying statements of
operations.

7. SHAREHOLDERS' EQUITY

Common Shares

The Company paid to common shareholders and to unitholders distributions
of $109.4 million, $70.6 million, and $52.6 million, during the years
ended December 31, 1998, 1997 and 1996. On a per share basis, the
Company paid common share distributions of $1.71, $1.65 and $1.61 during
the years ended December 31, 1998, 1997 and 1996.

For federal income tax purposes, the following table summarizes the
portions of the common share distributions relating to return of
capital, ordinary income, and capital gains:

1998 1997 1996
------ ------ ------

Return of capital - 30.4% 29.9%
Ordinary income 100.0% 68.4% 70.1%
Capital gains - 1.2% -

The Company's federal income tax returns are subject to examination by
taxing authorities. Because the application of tax laws and regulations
is susceptible to varying interpretations, the taxability of
distributions could be changed at a later date upon final determination
by taxing authorities.

Preferred Shares

On August 11, 1997 the Company issued 5,000,000 Series A Cumulative
Redeemable Preferred Shares (the "Preferred Shares"). The Preferred
Shares are non-voting and have a liquidation preference of $25.00 per
share. On or after July 30, 2002, the Preferred Shares may be redeemed
for cash at the option of the Company.

The Company paid preferred share distributions of $11.0 million and $2.4
million during the years ended December 31, 1998 and 1997. On a per
share basis, the Company paid preferred share distributions of $2.20 and
$0.48 during the years ended December 31, 1998 and 1997.

For federal income tax purposes, the following table summarizes the
portions of the preferred shares distributions relating to return of
capital, ordinary income and capital gains:

1998 1997
------ ------

Return of capital - -
Ordinary income 100.0% 95.3%
Capital gains - 4.7%

Minority Interest

Minority interest in the accompanying consolidated financial statements
relates to limited partnership interests of the Operating Partnership
issued in connection with the formation of the Company and certain
subsequent acquisitions. In connection with the acquisition of
properties for the years ended 1998 and 1997, the Company issued
1,049,846 and 1,197,739 units, respectively. The limited partnership
interests outstanding as of December 31, 1998 have the same economic
characteristics as would 5,245,220 Common Shares, inasmuch as they share
proportionately in the net income or loss and in any distributions of
the Operating Partnership and such interests are exchangeable into the
same number of Common Shares of the Trust.

Shareholder Rights Plan

In December 1997, the Board of Directors of the Company adopted a
shareholder rights plan (the "Shareholder Rights Plan"). Under the
Shareholder Rights Plan, one Right (as defined in the Shareholder Rights
Plan) was attached to each outstanding Common Share at the close of

- -48-

business on December 31, 1997. In addition, a Right will be attached to
each share of Common Stock issued in the future. Each Right entitles
the registered holder to purchase from the Company, under certain
conditions, a unit (a "Rights Plan Unit") consisting of one one-
thousandth of a share of a Series A Junior Participating Preferred
Share, $0.0001 par value, (the "Junior Preferred Stock"), of the
Company, for $100 per Rights Plan Unit, subject to adjustment. The
Rights become exercisable only if a person or group of affiliated or
associated persons (an "Acquiring Person") acquires, or obtains the
right to acquire, beneficial ownership of Common Shares or other voting
securities ("Voting Stock") that have 10% or more of the voting power of
the outstanding shares of Voting Stock, or if an Acquiring Person
commences with or makes an announcement of an intention to make a tender
offer or exchange offer to acquire beneficial ownership of Voting Stock
that have 10% or more of the voting power of the outstanding shares of
Voting Stock. The Rights are redeemable by the Company at a price of
$0.0001 per Right. If not exercised or redeemed, all Rights will expire
on December 31, 2007.

Dividend Reinvestment Plan

The Company has instituted a Dividend Reinvestment and Share Purchase
Plan under which holders of common shares may elect to automatically
reinvest their distributions in additional common shares and may make
optional cash payments for additional common shares. The Company may
issue additional common shares or repurchase common shares in the open
market for purposes of financing its obligations under the Dividend
Reinvestment and Share Purchase Plan.

8. SHARE OPTIONS

The Company has elected to follow Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for
under FASB Statement No. 123, "Accounting for Stock-Based Compensation,"
requires use of option valuation models that were not developed for use
in valuing employee stock options. Under APB 25, because the exercise
price of the Company's employee stock options equals the market price
of the underlying stock on the date of grant, no compensation expense is
recognized. Under FASB Statement No. 123, the Company would recognize
compensation expense equal to the value of such options upon grant date.

The Company's Share Incentive Plan ("Share Incentive Plan") has
authorized the grant of options to executive officers, other key
employees, non-employee trustees and consultants of up to 4,033,535
shares of the Company's Common Shares. All options granted have 10-year
terms and vest over a 3-year period, with options to purchase up to 20%
of the shares exercisable after the first anniversary, up to 50% after
the second anniversary and 100% after the third anniversary of the date
of grant.

Pro forma information regarding net income and earnings per share is
required by Statement 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method of
that Statement. The fair value for these options was estimated at the
date of grant using a Black-Scholes option pricing model with the
following weighted-average assumptions for 1998, 1997 and 1996,
respectively: risk-free interest rate of 4.7%, 5.5% and 6.2%;
dividend yield of 7.3%, 6.0% and 7.0%; volatility factor of the expected
market price of the Common Shares of .159, .155 and .164; and a

- -49-

weighted-average expected life of the option of 8 years, 3 years and 3
years.

The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting
restrictions and are fully transferable. In addition, option valuation
models require the input of highly subjective assumptions including the
expected stock price volatility. Because the Company's employee share
options have characteristics significantly different from those of
traded options, and because changes in the subjective input assumptions
can materially affect the fair value estimate, in management's opinion,
the existing models do not necessarily provide a reliable single measure
of the fair value of its employee share options.

For purposes of pro forma disclosures, the estimated fair value of the
options determined according to the Black-Scholes Option pricing model
is amortized to expense over the options' vesting period. The
Company's pro forma information follows (in thousands, except for per
share amounts):
1998 1997 1996
--------- --------- --------
Pro forma income available to
common shareholders $ 96,673 $ 55,538 $ 33,359

Pro forma income per common share:

Basic $ 1.58 $ 1.37 $ 1.13
Diluted $ 1.58 $ 1.36 $ 1.12

Pro forma disclosures are not likely to be representative of the effects
on reported net income for future years because of the staggered vesting
periods of the options.

A summary of the Company's share option activity, and related
information for the years ended December 31, 1998, 1997 and 1996
follows:

Exercise prices for options outstanding as of December 31, 1998 ranged
from $19.75 to $26.95. The weighted-average remaining contractual life
of those options is 7.4 years.

- -50-


An additional 1,033,276, 1,858,502, and 511,887 Common Shares were
reserved for issuance for future grants from the Share Incentive Plan at
December 31, 1998, 1997 and 1996, respectively.

9. COMMITMENTS AND CONTINGENCIES

All of the Properties and land were subject to Phase I Environmental
Assessments ("Phase I Assessments") obtained in contemplation of their
acquisition by the Company. The Phase I Assessments consisted of, among
other activities, a visual inspection of each Property and its
neighborhood and a check of pertinent public records. The Phase I
Assessments did not reveal, nor is the Company aware of, any non-
compliance with environmental laws, environmental liability or other
environmental claim that the Company believes would likely have a
material adverse effect on the Company.

In connection with one of the 1997 acquisitions, the Company is
obligated to purchase, over a 10-year period ending in 2007,
approximately 775 acres of land for commercial development. The
purchase price of the land as of December 31, 1998 is $16.2 million.

The Trust is not a party to any material legal proceedings. In the
ordinary course of business, the Operating Partnership is party to
routine litigation incidental to its business and in addition
it is covered by insurance.

11. SEGMENT INFORMATION

Liberty Property Trust operates its portfolio of properties throughout
the Southeastern, Mid-Atlantic and Midwestern United States. The
Company reviews performance of the portfolio on a geographical basis, as
such, the following regions are considered the Company's reportable
segments: Southeastern Pennsylvania; New Jersey/Delaware; Lehigh
Valley, Pennsylvania; Maryland; Virginia; the Carolinas; Jacksonville,
Florida; Tampa, Florida; South Florida; Minneapolis, Minnesota; Detroit,
Michigan; and the United Kingdom. The Company's reportable segments are
distinct business units which are each managed separately in order to

- -51-

concentrate and hone market knowledge within a geographical area.
Within these reportable segments, the Company derives its revenues from
its two product types: industrial and office properties.

The Company evaluates performance of the reportable segments based on
property level net operating income, which is calculated as rental
revenue and operating expense reimbursement less rental expenses and
real estate taxes. The accounting policies of the reportable segments
are the same as those described in the summary of significant accounting
policies.

REPORT OF INDEPENDENT AUDITORS



To The Partners
Liberty Property Limited Partnership



We have audited the accompanying consolidated balance sheets of Liberty
Property Limited Partnership ("the Operating Partnership") as of
December 31, 1998, and 1997, and the related consolidated statements of
operations, owners' equity, and cash flows for each of the three years
in the period ended December 31, 1998. Our audits also included the
financial statement schedule listed in the Index at Item 14(a). These
financial statements and schedule are the responsibility of the
Operating Partnership's management. Our responsibility is to express an
opinion on these financial statements and schedule based on our audits.

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

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial
position of Liberty Property Limited Partnership at December 31, 1998
and 1997, and the consolidated results of its operations and its cash
flows for each of the three years in the period ended December 31, 1998,
in conformity with generally accepted accounting principles. Also, in
our opinion, the related financial statement schedule, when considered
in relation to the basic financial statements taken as a whole, presents
fairly in all material respects the information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS OF
LIBERTY PROPERTY LIMITED PARTNERSHIP

1. ORGANIZATION

Liberty Property Trust (the "Trust") is a self-administered and self-
managed Maryland real estate investment trust (a "REIT"). Substantially
all of the Trust's assets are owned directly or indirectly, and
substantially all of the Trust's operations are conducted directly or
indirectly, by its subsidiary, Liberty Property Limited Partnership, a
Pennsylvania limited partnership (the "Operating Partnership" and,
together with the Trust and its consolidated subsidiaries, the
"Company"). The Trust is the sole general partner and also a limited
partner of the Operating Partnership, with a combined equity interest in
the Operating Partnership of 92.6% at December 31, 1998. The Company
provides leasing, property management, acquisition, development,
construction management, and design management for a portfolio of
industrial and office properties which are located principally within
the Southeastern, Mid-Atlantic and Midwestern United States.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

Principles of Consolidation

The Consolidated Financial Statements of the Company include the
accounts of the Operating Partnership and the Operating Partnership's
consolidated subsidiaries. All significant intercompany transactions and
accounts have been eliminated.

Certain amounts from prior periods have been restated to conform to
current year presentation.

Real Estate and Depreciation

The Properties are recorded at the lower of cost or fair value if
impaired and are depreciated using the straight-line method over their
estimated useful lives. The estimated lives are as follows:

Building and improvements 40 years
Equipment 10 years
Tenant improvements Term of the related lease

Expenditures directly related to acquisition, development or improvement
of real estate are capitalized as a cost of the property. Expenditures
for maintenance and repairs are charged to operations as incurred.

The Company evaluates its real estate investments upon occurrence of
significant adverse changes in their operations to assess whether any
impairment indications are present that affect the recovery of the
recorded value. If any real estate investment is considered impaired, a
loss is provided to reduce the carrying value of the property to its
estimated fair value.

- -87-


Cash and Cash Equivalents

Highly liquid investments with a maturity of three months or less when
purchased are classified as cash equivalents. The carrying amount of
these assets approximates their fair market value.

Revenues

The Company earns rental income under operating leases with tenants.
Rental income is recognized on a straight-line basis over the applicable
lease term.

Deferred Financing and Leasing Costs

Costs incurred in connection with financing or leasing are capitalized
and amortized over the term of the related loan or lease. Amortization
of deferred financing costs is reported as interest expense.

Income Taxes

In conformity with the Internal Revenue Code and applicable state and
local tax statutes, taxable income or loss of the Operating Partnership
is required to be reported in the tax returns of the partners in
accordance with the terms of the Partnership Agreement and, accordingly,
no provision has been made in the accompanying financial statements for
any federal, state, or local income taxes.

Impact of Recently Issued Accounting Standards

In June 1998, the FASB issued Statement No. 133, "Accounting for
Derivative Instruments and Hedging Activities". The Company expects to
adopt the new Statement effective January 1, 2000. The Statement will
require the Company to recognize all derivatives on the balance sheet at
fair value. The Company does not anticipate that the adoption of this
statement will have a significant effect on its results of operations or
financial position.

3. REAL ESTATE

At December 31, 1998 and 1997, the Company owned and operated industrial
and office properties located principally in suburban mixed use
developments or business parks. The carrying value of these properties

Depreciation expense was $61.7 million in 1998, $36.0 million in 1997
and $25.0 million in 1996.

As of December 31, 1998, the Company has commenced development on 45
properties in 11 markets, which upon completion are expected to comprise
approximately four million square feet of leaseable space. As of
December 31, 1998 approximately $207.6 million has been expended for the
development of these projects and an additional $160.2 million is
required for completion.

4. RELATED PARTY TRANSACTIONS

Pursuant to agreements, the Company has been retained by an affiliate
(Rouse Kent Limited) to provide development, management and other
services. For the years ended December 31, 1998, 1997 and 1996
the fees for these services were $600,000 per year. The Company has a
loan receivable from Rouse Kent Limited with a balance of $5.9 million
and $5.5 million as of December 31, 1998 and 1997, respectively.

5. INDEBTEDNESS

Indebtedness consists generally of mortgage loans, unsecured notes, the
credit facility, and convertible debentures. The weighted average
interest rates as of December 31, 1998, 1997 and 1996, were
approximately 7.2%, 7.5% and 7.6%, respectively. Interest expense for
the years ended December 31, 1998, 1997 and 1996, aggregated $78.6
million, $53.9 million and $38.5 million, respectively. Interest costs
during these periods of $16.3 million, $11.8 million and $7.7 million,
were capitalized. Cash paid for interest for the years ended December
31, 1998, 1997 and 1996, was $83.2 million, $54.9 million and $43.7
million, respectively.

Mortgage Loans, Unsecured Notes

Mortgage loans with maturities ranging from 1999 to 2013 are
collateralized by and in some instances cross-collateralized by
properties with a book value of $602.6 million.

As of December 31, 1998, $413.2 million in mortgage loans and $645.0
million in unsecured notes were outstanding. The interest rates on
$1,041.6 million of mortgage loans and unsecured notes are fixed and
range from 5.0% to 9.1%. Interest rates on $16.6 million of mortgage
loans float with LIBOR, prime or a municipal bond index, $10.0 million
of which is subject to certain caps. The weighted average remaining
term for the mortgage loans and unsecured notes is 8.5 years. The
scheduled maturities of principal amortization of the Company's mortgage

- -89-

loans and unsecured notes outstanding and the related weighted average
interest rates are as follows:

======== ======== ======== ========== =====


Credit Facility

The credit facility is a $325 million unsecured credit facility (the
"Credit Facility") which replaced two existing secured lines of credit
aggregating $350 million in May 1997. Coincident with the replacement
of the lines of credit, $2.9 million of related deferred financing costs
were charged to interest expense. The interest rate on borrowings under
the Credit Facility fluctuates, based on the Company's leverage levels
and senior debt ratings from Moody's Investors Service, Inc. ("Moody's")
and Standard & Poor's Ratings Group ("Standard & Poor's"). The current
ratings for the Company's senior unsecured debt are Baa3 and BBB- from
Moody's and Standard & Poor's, respectively. At these ratings, the
current interest rate on the Credit Facility is 110 basis points over
the LIBOR (6.67% at December 31, 1998). The rate for the Credit
Facility at December 31, 1997 was 7.09%. Customary fees apply to the
Credit Facility including an annual administrative fee and an unused
line fee. The Credit Facility matures on May 20, 1999, and can be
extended for one year for $650,000.

On January 15, 1999 the Company closed a $135 million, two-year
unsecured term loan. The interest rate for the loan is 135 basis points
over LIBOR.

Convertible Debentures

The convertible debentures are due on June 23, 2001 and are exchangeable
for common shares of beneficial interest of the Trust (the "Common
Shares") at a rate of one Common Share for each $20 outstanding
principal amount of convertible debentures, subject to certain
adjustments. The initial interest rate on the convertible debentures
was 8.0% and increases with increases in the dividend payment on the
Company's Common Shares. At the current $.45 per common share per
quarter dividend payment rate, the effective interest rate on the

- -90-

convertible debentures is 9.0%. At December 31, 1997, the effective
interest rate on the convertible debentures was 8.4%. During the year
ended December 31, 1997, the Company paid sums aggregating $98,000 to
facilitate the conversion of $17.3 million of convertible debentures
into 862,650 Common Shares. There was no such expense in 1998. At
December 31, 1998 and 1997 the convertible debentures were convertible
into 5,080,950 and 5,577,150 Common Shares, respectively.

The fair value of the convertible debentures at December 31, 1998 was
$125.1 million based on the closing bid price of the Company's Common
Shares on the New York Stock Exchange. The fair values of the
mortgages, the unsecured notes and Credit Facility were estimated using
discounted cash flow analysis, based on the Company's estimated
incremental borrowing rate at December 31, 1998, for similar types of
borrowing arrangements. The carrying values of the mortgages, the
unsecured notes and the Credit Facility approximate their fair values.

6. LEASING ACTIVITY

Future minimum rental payments due from tenants under non-cancellable
operating leases as of December 31, 1998 are as follows (in thousands):

1999 $ 306,662
2000 267,891
2001 218,764
2002 180,641
2003 144,407
Thereafter 508,082
----------
TOTAL $1,626,447
==========

In addition to minimum rental payments, tenants pay for their pro rata
share of specified operating expenses. These amounts are included as
operating expense reimbursement in the accompanying statements of
operations.

7. PREFERRED UNITS

On August 11, 1997 the Company issued 5,000,000 Series A Cumulative
Redeemable Preferred Units (the "Preferred Units"). All of the
Preferred Units are held by the Trust. The Preferred Units are non-
voting and have a liquidation preference of $25.00 per unit and a
preferential cash distribution rate of 8.8%. On or after July 30, 2002,
the Preferred Units may be redeemed for cash at the option of the
Company.

8. COMMITMENTS AND CONTINGENCIES

All of the Properties and land were subject to Phase I Environmental
Assessments ("Phase I Assessments") obtained in contemplation their
acquisition by the Company. The Phase I Assessments consisted of, among
other activities, a visual inspection of each Property and its
neighborhood and a check of pertinent public records. The Phase I
Assessments did not reveal, nor is the Company aware of, any non-
compliance with environmental laws, environmental liability or other
environmental claim that the Company believes would likely have a
material adverse effect on the Company.

In connection with one of the 1997 acquisitions, the Company is
obligated to purchase, over a 10-year period ending in 2007,

- -91-

approximately 775 acres of land for commercial development. The
purchase price of the land as of December 31, 1998 is $16.2 million.

The Operating Partnership is not a party to any material legal
proceedings. In the ordinary course of business, the Operating
Partnership is party to routine litigation incidental to its business
and in addition it is covered by insurance.

10. SEGMENT INFORMATION

Liberty Property Trust operates its portfolio of properties throughout
the Southeastern, Mid-Atlantic and Midwestern United States. The
Company reviews performance of the portfolio on a geographical basis, as
such, the following regions are considered the Company's reportable
segments: Southeastern Pennsylvania; New Jersey/Delaware; Lehigh
Valley, Pennsylvania; Maryland; Virginia; the Carolinas; Jacksonville,
Florida; Tampa, Florida; South Florida; Minneapolis, Minnesota; Detroit,
Michigan; and the United Kingdom. The Company's reportable segments are
distinct business units which are each managed separately in order to
concentrate and hone market knowledge within a geographical area.
Within these reportable segments, the Company derives its revenues from
its two product types: industrial and office properties.

The Company evaluates performance of the reportable segments based on
property level net operating income, which is calculated as rental
revenue and operating expense reimbursement less rental expenses and
real estate taxes. The accounting policies of the reportable segments
are the same as those described in the summary of significant accounting
policies.
