harbor" for forward-looking statements. Certain information included in
this Annual Report on Form 10-K and other materials filed or to be filed
by the Company (as defined below) with the Securities and Exchange
Commission (as well as information included in oral statements or other
written statements made or to be made by the Company) contain statements
that are or will be forward-looking, such as statements relating to
business development and development activities, acquisitions, (including
related pro forma financial information) dispositions, future capital
expenditures, financing sources and availability, and the effects of
regulation (including environmental regulation) and competition. Such
forward-looking information involves important risks and uncertainties
that could significantly affect anticipated results in the future and,
accordingly, such results may differ from those expressed in any forward-
looking statements made by, or on behalf of, Liberty Property Trust and
Liberty Property Limited Partnership (together, the "Company"). These
risks and uncertainties include, but are not limited to, uncertainties
affecting real estate businesses generally (such as entry into new
leases, renewals of leases and dependence on tenants' business
operations), risks relating to construction and development activities,
acquisition, disposition, possible environmental liabilities, risks
relating to leverage and debt service (including availability of
financing terms acceptable to the Company and sensitivity of the
Company's operations and financing arrangements to fluctuations in
interest rates), the potential for the use of borrowings to make
distributions necessary to qualify as a REIT, dependence on the primary
markets in which the Company's properties are located, the existence of
complex regulations relating to status as a REIT and the adverse
consequences of the failure to qualify as a REIT, and the potential
adverse impact of market interest rates on the market price for the
Company's securities. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations - Forward-Looking

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 in 1994 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, 1999,
consisted of 634 industrial and office properties (the "Properties in
Operation") totaling approximately 46.2 million leasable square feet. As
of December 31, 1999, the Properties in Operation were approximately
94.9% leased to over 1,900 tenants. As of December 31, 1999, the
Company also had 22 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 2.2 million leasable square
feet. The Properties are located principally within the Southeastern,
Mid-Atlantic and Midwestern United States. As of December 31, 1999, the
Company also owned 1,307 acres of land, all zoned for commercial use,
which the Company anticipates are capable of supporting, as and when
developed, approximately ten million leasable square feet.

During the year ended December 31, 1999, through Total Investments (as
defined below) aggregating $348.9 million, the Company increased its
total leasable square footage of industrial and office space
approximately 4.6% by developing 41 properties totaling approximately
3.4 million leasable square feet and by acquiring 13 properties totaling
approximately 775,000 leasable square feet. This increase is net of the
disposition of 28 properties totaling approximately 2.1 million leasable
square feet for approximately $109.9 million. The "Total Investment"
for a Property is defined as the Property's purchase price plus closing
costs and management's estimate, as determined at the time of
acquisition, of the cost of necessary building improvements in the case
of acquisitions, or land costs and land and building improvement costs
in the case of development projects, and, where appropriate, other
development costs and carrying costs required to reach rent
commencement.

The Properties in Operation, as of December 31, 1999, consisted of 422
industrial and 212 office properties. Single tenants occupied 254 of
the Properties in Operation. The remaining 380 of the Properties in
Operation are multi-tenant properties for which the Company renders a
range of building, operating and maintenance services.

- -5-

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. 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 common equity interest in the
Operating Partnership of 93.2% at December 31, 1999. The common units
of limited partnership interest in the Operating Partnership (the
"Common 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 Common
Units. The only limited partners of the Operating Partnership who hold
Common Units other than the Trust are persons or entities that
contributed assets to the Operating Partnership and received Common
Units in exchange therefor. The Common Units held by the limited
partners other than the Trust were exchangeable for approximately 4.9
million Common Shares on December 31, 1999. Certain holders of Common
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 Common
Units upon exchange for the Common Units, in order to afford such
holders liquidity with respect to their investment. The Company has
issued Series B Cumulative Redeemable Preferred Units of the Operating
Partnership (the "Preferred Units"). The Preferred Units are
exchangeable on a one-for-one basis at any time on or after July 28,
2009 into Series B Cumulative Redeemable Preferred Shares.
Collectively, the ownership of the Common and Preferred Unitholders is
reflected on the Trust's financial statements as minority interest.

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, 1999, the Company's principal markets were as follows:
Southeastern Pennsylvania; New Jersey; Lehigh Valley, Pennsylvania;
Maryland; Virginia; the Carolinas; Jacksonville, Florida; Tampa,
Florida; South Florida; Minneapolis, Minnesota; Detroit, Michigan; and
the United Kingdom. For further detail regarding the Company's
Properties in particular markets, please refer to Item 2. Properties and
Note 11 of the Notes to the Liberty Property Trust Financial Statements
and Note 10 of the Notes to the Liberty Property Limited Partnership
Financial Statements.

MANAGEMENT AND EMPLOYEES

The Company's 331 employees (as of February 22, 2000) are under the
direction of 19 senior executives, who, on average, have been affiliated
with the Company and the Predecessor for 14 years. The Company and its
Predecessor has developed and managed commercial real estate for the
past 27 years. The Company's in-house leasing, marketing and property
management staff operates in full-service local offices in markets where

- -6-


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, (ii) developing and acquiring high-quality properties, and
(iii) selectively disposing of certain 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. 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. In addition, 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, and by improving the occupancy of its portfolio. The Company
also intends to enhance its ability to attract and retain tenants by
pursuing various e-commerce initiatives. 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, 1999 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, 2000. The Company intends to continue 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.

E-COMMERCE INITIATIVES. The Company believes that its Properties
represent unique resources the value of which can be increased by the
addition of tenant-oriented amenities.

The Company has developed and commenced the introduction of a new
Internet-based product to link the Company's business communities with

- -7-


local service providers, national retailers and community organizations.
The Company believes that this product will enhance the working
environment in the business parks in which many of the Company's
Properties are located. The Company believes that this focus will
further the Company's goal of providing desirable business
accommodations for its tenants.

In another initiative, the Company has entered into an agreement with a
telecommunications service provider to make available to tenants a
portfolio of e-commerce solutions, including advanced voice and data
services and broadband Internet access. In exchange for access to the
Company's Properties, the telecommunications service provider has agreed
to wire substantially all of the Company's multi-tenant office
Properties and certain of its flex Properties. The arrangement provides
that the Company will participate in a portion of the revenue generated
by the tenants' use of such services. The Company believes that the
relationship with this telecommunications service provider will allow
the Company to offer its tenants an attractive e-commerce amenity and
may result in additional revenue as a product of the revenue sharing
arrangement.

The Company intends to continue to explore and develop various
e-commerce initiatives in order to maximize the value of its assets.

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.

DEVELOPMENT, ACQUISITION AND DISPOSITION STRATEGIES

The Company also seeks to achieve growth in income from rental
operations through maintenance and expansion of its development
pipeline, and acquisition of additional rental properties where
management has identified opportunities which will create shareholder
value over the long term. The Company also has a program to dispose of
Properties which no longer fit with the Company's strategic objective or
in situations where it can optimize cash proceeds.

The Company pursues attractive development opportunities, focusing
primarily on high-quality suburban industrial and office properties
within its existing markets. The Company and its Predecessor have
developed over 41 million square feet of commercial real estate during
the past 27 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. 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.

DEVELOPMENT. During the year ended December 31, 1999, the Company
completed 8 build-to-suit and 33 inventory projects, totaling

- -8-


approximately 3.4 million square feet of leasable space and representing
an aggregate Total Investment of approximately $285.7 million. As of
December 31, 1999, these completed development properties were 88.1%
leased.

As of December 31, 1999, the Company had 22 Properties Under Development
which, upon completion, are expected to generate approximately 2.2
million leasable square feet and are expected to represent a Total
Investment of approximately $198.1 million. Approximately 33.7% of such
leasable space was pre-leased as of December 31, 1999. The Company
expects to complete the Properties Under Development over the next eight
quarters.

As of December 31, 1999, the Company owned 1,307 acres of land for
development, all zoned for commercial use. Substantially all of the land
is 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 ten million leasable
square feet. The Company's investment in land held for development as
of December 31, 1999 was $111.2 million. The Company is obligated to
purchase additional land under contracts entered into with a variety of
parties. 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.

ACQUISITIONS. 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.

During the year ended December 31, 1999, the Company acquired 13
properties comprising approximately 775,000 leasable square feet for a
Total Investment of $63.1 million.

DISPOSITIONS. The Company seeks to generate capital through its asset
disposition program pursuant to which Properties in Operation which no
longer fit within the Company's strategic plan are sold and the proceeds
from such sales are utilized to fund development and acquisitions
consistent with the Company's business objectives and strategies.
During the year ended December 31, 1999, the Company sold 28 Properties
compromising approximately 2.1 million square feet of leasable space for
$109.9 million.

INTERNATIONAL OPERATION

The Company's international operation includes nine Properties in
Operation and one Property Under Development 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 accounts and a loan
receivable from Rouse Kent Limited at December 31, 1999, with
outstanding balances of $5.1 million.

- -9-


SUBSEQUENT ACTIVITIES

The Company intends to continue to pursue its development, acquisition
and disposition strategies. The Company is currently in various stages
of discussions and negotiations with respect to development, acquisition
and disposition projects. The consummation of these or any other future
developments, or acquisitions and dispositions, if any, and the pace at
which developments may be completed and acquisitions and dispositions
made, cannot be assured.

COMPETITION

The Company faces competition as a lessor, developer, buyer, and seller
of properties. The Company believes that the quality of its Properties
and its responsiveness to tenant needs will enable it to attract and
retain high-quality tenants in the markets in which the Properties 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 develop or acquire properties. However, the Company
believes that its management, its market knowledge, 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,
treated 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 storage, disposal or treatment facility or other
facility at which there has been a release or a threatened release of
such substances, 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 developed or acquired
hereafter, the Company may be potentially liable for removal,
remediation, natural resource damages, release or injury to persons or
property. 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

- -10-


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-
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, 1999, consisted of 422
industrial and 212 office properties.

Single tenants occupy 254 Properties in Operation. The Company provides
a reduced level of service in connection with the operation or
maintenance of these properties. The remaining 380 of the Company's
Properties in Operation are multi-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 offering excellent access to interstate highway systems 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 76,379 leasable
square feet. As of December 31, 1999, the Company's industrial
properties were 94.8% leased. Major industrial tenants, based upon
annual base rent, include DSC Logistics, Inc., the Government of the
United States of America, General Electric Company, and Dial
Corporation. None of the industrial tenants accounts for more than 1.3%
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, 1999, the
office properties were approximately 95.0% leased. The average building
size of the office properties is 65,975 leasable square feet. Major
office tenants, based upon annual base rent, include The Vanguard Group,
SmithKline Beecham, Citigroup, and the Prudential Insurance Company.

total annual base rent.

The table below sets forth certain information on the Company's
Properties in Operation as of December 31, 1999. A complete listing of
the Properties in Operations appears as Schedule III to the financial

ITEM 3. LEGAL PROCEEDINGS

The ownership of property and provision of services to the public
entails an inherent risk of liability. Although the Company is engaged
in litigation incidental to its business, there is no legal proceeding
to which it is a party which, in the opinion of management, will
materially adversely affect the results of the Company's operations.
The Company carries liability insurance against certain types of claims
that management believes meets industry standards; however, there can be
no assurance that any future legal proceedings (including any related
judgments, settlements or costs) will not materially adversely affect
the Company's financial condition, liquidity, or results of operations.

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 sold the Church Road Properties in 2000. The Company has not
been similarly notified by the EPA; however, as a prior 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.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matters were submitted to a vote of security holders during the
fourth quarter of the year ended December 31, 1999.

PART II

ITEM 5. MARKET FOR THE REGISTRANTS' COMMON EQUITY AND RELATED
SHAREHOLDERS MATTERS

The Common Shares are traded on the New York Stock Exchange under the
symbol "LRY." There is no established public trading market for the
Common Units. The following table sets forth, for the calendar quarters
indicated, the high and low closing prices of the Common Shares on the
New York Stock Exchange, and the dividends declared per Common Share for
such calendar quarter.

DIVIDENDS
DECLARED PER

As of February 22, 2000, the Common Shares were held by 1,114 holders of
record. Since its initial public offering, the Company has paid regular
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
cash flow, its financial condition, capital requirements, annual
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.

ITEM 6. SELECTED FINANCIAL DATA

Basic weighted average number of shares includes only Common

Diluted weighted average number of shares outstanding includes the

"Funds from operations" is defined by the National Association of
Real Estate Investment Trusts ("NAREIT") as net income or loss after
preferred distributions (computed in accordance with generally accepted
accounting principles ("GAAP")), excluding gains (or losses) from sales
of property and extraordinary items as defined by GAAP, plus real
estate-related depreciation and amortization and minority interest.
Funds from operations does not represent net income or cash flows
generated 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.

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,
1999, 1998 and 1997 are included in Note 11 of the Notes to the Liberty

- -17-


Property Trust Financial Statements and Note 10 of the Liberty Property
Limited Partnership Financial Statements.

In 1999, the Company continued to focus on creating value and increasing
profitability and cash flow. With respect to its core portfolio of
Properties in Operation the Company endeavors to maintain and increase
its high occupancy levels while increasing rental rates. The Company
pursues development opportunities that create value and yield high
returns. The Company also acquires properties which provide high
returns and create long-term value, and disposes of Properties which no
longer fit with the Company's strategic objectives or in situations
where it can optimize cash proceeds.

The Company's operating results depend primarily upon income from rental
operations. This income is substantially influenced by rental demand
for the Properties in Operation. 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, to
develop new properties to meet demand and to strategically acquire
additional properties and dispose of existing properties. The occupancy
rate of the Properties in Operation has been in the 94% to 95% range for
the last three years and was 94.9% at December 31, 1999. 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 increasing occupancy, along with increases in 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 seeks to achieve growth in income from rental
operations through controlling expenses, maintenance and expansion of
its development pipeline, and acquisition of additional rental
properties where management has identified opportunities which will
create shareholder value over the long term.

The number of properties brought into service increased in 1999 compared
to 1998. In 1999, the Company completed development of 41 properties
totaling approximately 3.4 million leasable square feet for a Total
Investment of $285.7 million. In 1998, the Company completed
development of 34 properties totaling approximately 3.5 million leasable
square feet for a Total Investment of $237.3 million. In addition, as
of December 31, 1999, the Company had 22 Properties Under Development
expected to generate, upon completion, approximately 2.2 million
leasable square feet of suburban office and industrial space for a Total
Investment of approximately $198.1 million. The Company expects to
complete the Properties Under Development over the next eight quarters.

The Company acquired 13 properties consisting of approximately 775,000
leasable square feet during 1999 for a Total Investment of approximately
$63.1 million as compared to the acquisition of 144 properties
consisting of approximately 8.6 million leasable square feet during 1998
for a Total Investment of approximately $626.3 million. The Company
will seek to continue to achieve attractive returns on acquisitions.
The Company anticipates that given current market conditions, the pace
of acquisitions of rental properties in 2000 will be approximately the
same as it was in 1999.

In 1999, the Company disposed of 28 Properties totaling approximately
2.1 million leasable square feet for $109.9 million. In 1998, the
Company disposed of ten Properties totaling approximately 412,000
leasable square feet for $18.9 million. The Company anticipates the
selective disposition of Properties to continue.

- -18-


The Company continued to strengthen its balance sheet in 1999 by
accessing both the private equity market and the public debt market.
The Company raised approximately $95.0 million through the issuance of
9.25% Series B Cumulative Redeemable Preferred Units. In addition, the
Company issued $250.0 million principal amount of investment grade rated
10-year unsecured notes.

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:
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, 1999 with the results of
operations of the Company for the year ended December 31, 1998, and 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. As a result of the significant level of development,
acquisition and disposition activities by the Company in 1999 and 1998,
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, 1999 TO YEAR ENDED DECEMBER 31,
1998.

Total revenue (principally rental revenue and operating expense
reimbursement) increased to $472.5 million for the year ended December
31, 1999 from $388.4 million for the year ended December 31, 1998. This
increase was primarily due to the increase in the number of Properties
in Operation during the respective periods. As of January 1, 1998, the
Company had 441 Properties in Operation, and, through December 31, 1998,
completed the development on 34 properties, acquired 144 additional
properties for a Total Investment (as defined below) of $863.6 million,
and disposed of 10 Properties for $18.9 million. As of January 1, 1999,
the Company had 608 Properties in Operation and, through December 31,
1999, completed development on 41 properties, acquired 13 additional
properties for a Total Investment of $348.9 million, and disposed of 28
Properties for $109.9 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 95.5% for the year ended December 31, 1999
from 93.4% for the year ended December 31, 1998 due to the increase in
average occupancy during the year. 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,

- -20-


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 $129.4 million
for the year ended December 31, 1999 from $108.3 million for the year
ended December 31, 1998. This increase is due to the increase in the
number of Properties in Operation.

Property level operating income for the "Same Store" properties
(properties owned since January 1, 1998) increased to $219.6 million for
the year ended December 31, 1999 from $209.9 million for the year ended
December 31, 1998, with straightlining (which recognizes rental revenue
evenly over the life of the lease), and increased to $216.3 million for
the year ended December 31, 1999 from $206.7 million for the year ended
December 31, 1998, without straightlining. These increases, each
equaling 4.6%, are primarily due to increases in rental rates, and to a
modest extent due to 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, 1999 and 1998(in thousands).

General and administrative expenses increased to $16.1 million for the
year ended December 31, 1999 from $15.5 million for the year ended
December 31, 1998. This $600,000 increase is due to the increase in
personnel and other related overhead costs necessitated by the increase
in the number of Properties in Operation 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 in Operation.

Depreciation and amortization expenses increased to $84.5 million for
the year ended December 31, 1999 from $67.9 million for the year ended
December 31, 1998. This increase is due to the increase in the number
of Properties in Operation during the respective periods.

Interest expense increased to $99.7 million for the year ended December
31, 1999 from $78.6 million for the year ended December 31, 1998. This
increase is due to an increase in the average debt outstanding for the
respective periods which was $1,474.6 million in 1999 and $1,233.3
million in 1998. This increase is also due to an increase in the
weighted average interest rates for the periods, to 7.33% in 1999 from
7.29% in 1998.

- -21-


In 1999, the Company realized a gain on sale of $13.2 million, due to
the sale of 28 Properties for $109.9 million. In 1998, the Company
realized a loss on sale of $1.3 million, due to the sale of 10
Properties for $18.9 million.

In 1999, the Company repurchased $6.6 million principal amount of its
Convertible Debentures. This resulted in the recognition of an
extraordinary loss in 1999 of $1.1 million. This loss represented the
redemption premium and the write-off of related deferred financing
costs. There were no extraordinary items in 1998.

As a result of the foregoing, the Company's income before minority
interest increased to $154.8 million for the year ended December 31,
1999 from $116.7 million for the year ended December 31, 1998. In
addition, net income increased to $141.3 million for the year ended
December 31, 1999 from $108.6 million for the year ended December 31,
1998.

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

Total revenue (principally rental revenue and operating expense
reimbursement) increased to $388.4 million for the year ended December
31, 1998 from $230.0 million for the year ended December 31, 1997. This
increase was primarily due to the increase in the number of Properties
in Operation during the respective periods. As of January 1, 1997, the
Company had 259 Properties in Operation and, through December 31, 1997,
completed development on 20 properties, acquired 170 additional
properties for a Total Investment of $871.5 million and disposed of
eight Properties for $35.4 million. As of January 1, 1998, the Company
had 441 Properties in Operation, and, through December 31, 1998,
completed the development on 34 properties, acquired 144 additional
properties for a Total Investment of $863.6 million, and disposed of 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.

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 in Operation.

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, 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.

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 in Operation 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 in Operation. 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 in Operation during the respective periods.

Interest expense increased to $78.6 million for the year ended December
31, 1998 from $51.1 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 offset by a decrease in the weighted average
interest rates for the periods, to 7.3% in 1998 from 7.5% in 1997.

In 1998, the Company realized a loss on sale of $1.3 million, due to the
sale of 10 Properties for $18.9 million. In 1997, the Company realized
a gain on sale of $2.5 million, due to the sale of 8 Properties for
$35.4 million.

In 1997, the Company replaced its two existing secured lines of credit
aggregating $350 million with a $325 million unsecured credit facility.
This resulted in the recognition of an extraordinary loss in 1997 of
$2.9 million. This loss represented the write-off of related deferred
financing costs. There were no extraordinary items in 1998.

As a result of the foregoing, the Company's 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. In
addition, net income increased to $108.6 million for the year ended
December 31, 1998 from $60.4 million for the year ended December 31,
1997.

- -23-


LIQUIDITY AND CAPITAL RESOURCES

As of December 31, 1999, the Company had cash and cash equivalents of
$9.1 million.

Net cash flow provided by operating activities decreased to $212.4
million for the year ended December 31, 1999 from $219.2 million for the
year ended December 31, 1998. This $6.8 million decrease was primarily
due to the 1998 increase in other liabilities and the 1999 increase in
other assets, offset by the additional cash flow generated by the
greater number of Properties in Operation 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 in Operation.

Net cash used in investing activities decreased to $238.8 million for
the year ended December 31, 1999 from $839.5 million for the year ended
December 31, 1998. The primary reason for this $600.7 million decrease
was a reduction in investment in Properties in Operation due to a
decrease in the number of attractive acquisition opportunities available
in 1999 compared to 1998. Furthermore, due to this market situation,
the Company increased the level of its asset dispositions in 1999
compared to 1998.

Net cash provided by financing activities decreased by $558.6 million to
$21.0 million for the year ended December 31, 1999 from $579.6 million
for the year ended December 31, 1998. Net cash provided by financing
activities includes proceeds from the issuance of equity and debt net of
debt repayments and shareholder distributions. It is a source of
capital utilized by the Company to fund investment activities and the
decrease in such funding activities for 1999 is consistent with the
decrease in the level of the Company's investment activities as
described above.

The Company believes that its undistributed cash flow from operations is
adequate to fund its operating needs.

The Company funds its development and acquisitions with long-term
capital sources to include proceeds from the disposition of Properties.
These activities may be funded on a temporary basis through its $325.0
million unsecured line of credit (the "Credit Facility"), which matures
in May 2000. The Company is in the process of negotiating a new credit
facility. The Company uses debt financing to lower its overall cost of
capital which increases our return to our shareholders. The Company
staggers its debt maturities and maintains debt levels it considers to
be prudent. In determining its debt levels, the Company considers
various financial measures to include debt to gross assets and interest
coverage and earnings to fixed charges ratios. The Company's capital
structure and financial policies have earned the Company prospective
senior debt ratings of BBB- from Standard and Poor's Ratings Group
("S&P") and Baa3 from Moody's Investors Services, Inc. ("Moody's").

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. At the Company's current ratings, the interest rate for borrowings
under the Credit Facility is 110 basis points over LIBOR.

As of December 31, 1999, $374.8 million in mortgage loans and $985.0
million in unsecured notes were outstanding. The interest rates on

- -24-


$1,263.5 million of mortgage loans and unsecured notes are fixed and
range from 5.0% to 9.1%. Interest rates on $6.3 million of mortgage
loans float with a municipal bond index. The weighted average remaining
term for the mortgage loans and unsecured notes is 7.6 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 (in thousands):

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 1999 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 (or a replacement credit facility) from time to
time.

In 1999, the Company received $93.0 million in aggregate net proceeds
from the issuance of 9.25% Series B Cumulative Redeemable Preferred
Units, $135.0 million from the closing of a two-year unsecured term
loan, and $246.0 million in aggregate net proceeds from the issuance of
unsecured notes. The Company used the aggregate net proceeds from
issuance of the preferred units, term loan and unsecured notes to fund
the Company's activities, including paying down the credit facility,
which funds development and acquisition activity.

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 development and acquisition activity.

- -25-


In connection with the acquisition of properties during the year ended
December 31, 1998, the Company issued 1,049,846 common units. No common
units were issued in connection with the acquisition of properties in
the year ended December 31, 1999.

In October 1999, the Board of Trustees authorized a share repurchase
program under which the Company may purchase up to $100 million of the
Company's Common Shares or Convertible Debentures. Through December 31,
1999, the Company purchased 59,100 Common Shares and purchased
Convertible Debentures exchangeable into 332,250 Common Shares. The
total cost for the purchase of the Common Shares and Convertible
Debentures was approximately $9 million.

In September 1999, the quarterly Common Share dividend was increased to
$0.52 per share from $0.45 per share. The Company's annual Common Share
dividend paid was $1.87 per share, $1.71 per share and $1.65 per share
in 1999, 1998 and 1997, respectively. In 1999, the Company's dividend
payout ratio was approximately 65% of funds from operations per share.

The Company has an effective S-3 shelf registration statement on file
with the Securities and Exchange Commission (the "Shelf Registration
Statement"). As of February 22, 2000, pursuant to the Shelf
Registration Statement, the Trust has the capacity to issue up to $688.4
million in equity securities and the Operating Partnership has the
capacity to issue up to $108.0 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 distributions (computed in accordance
with generally accepted accounting principles ("GAAP")), excluding gains
(or losses) from sales of property and extraordinary items as defined by
GAAP, plus real estate-related depreciation and amortization and
minority interest. 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, 1999, 1998 and 1997 are as follows:

IMPACT OF YEAR 2000

In prior filings, the Company discussed the nature and progress of its
plans to become Year 2000 ready. In 1999, the Company completed its
remediation and testing of systems. As a result of those planning and
implementation efforts, the Company experienced no significant
disruptions in mission-critical information technology and non-
information technology systems and believes those systems successfully
responded to the Year 2000 date change. The expenses incurred during
1999 in connection with remediating the Company's systems were not
material. The Company is not aware of any material problems resulting
from Year 2000 issues, either with its Properties, its internal systems,
or the products and services of third parties. The Company will
continue to monitor its mission-critical computer applications and those
of its suppliers and vendors throughout the Year 2000 to ensure that any
latent Year 2000 matters that may arise are addressed promptly.

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 tenants' 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.

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 rates for variable rate debt were 100 basis points
higher or lower during 1999, the Company's interest expense would have

- -27-


been increased or decreased by approximately $1.8 million. If the
interest rates for fixed rate debt maturing and to be refinanced in 2000
are 100 basis points higher or lower than its current weighted average
rate of 8.7%, the Company's interest expense would be increased or
decreased by approximately $13,000.

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, 1999 and 1998, and the
related consolidated statements of operations, shareholders' equity, and
cash flows for each of the three years in the period ended December 31,
1999. 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 auditing standards generally
accepted in the United States. 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, 1999 and 1998, and
the consolidated results of its operations and its cash flows for each
of the three years in the period ended December 31, 1999, in conformity
with accounting principles generally accepted in the United States.

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 common equity
interest in the Operating Partnership of 93.2% at December 31, 1999.
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 accounting
principles generally accepted in the United States 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.

Reclassifications

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:

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

Expenditures directly related to development, acquisition, 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

- -35-


impairment indicators 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. As of December 31, 1999 and 1998, none of the
Company's assets was considered impaired.

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 (in thousands, except per share amounts):

----------- ------------

Diluted income per common share
Income available to common

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


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 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 $1.96 calculated as if the
debenture conversions which occurred in 1999 had occurred on January 1,
1999.

Income Taxes

The Company has elected to be taxed as a REIT under Sections 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
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, 1999 was
approximately $3.1 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, 2001. 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.

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


Depreciation expense was $74.8 million in 1999, $61.7 million in 1998,
and $36.0 million in 1997.

As of December 31, 1999, the Company has commenced development on 22
properties, which upon completion are expected to comprise approximately
2.2 million square feet of leasable space. As of December 31, 1999,
approximately $138.9 million has been expended for the development of
these projects and an additional $59.2 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, 1999, 1998, and 1997, the
fees for these services were $600,000 per year. The Company had accounts
and a loan receivable from Rouse Kent Limited with balances of $5.1
million and $6.5 million as of December 31, 1999 and 1998, 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, 1999, 1998, and 1997, were
approximately 7.3%, 7.2%, and 7.5%, respectively. Interest expense for
the years ended December 31, 1999, 1998, and 1997, aggregated $99.7
million, $78.6 million, and $51.1 million, respectively. Interest costs
during these periods of $15.3 million, $16.3 million, and $11.8 million,
respectively, were capitalized. Cash paid for interest for the years
ended December 31, 1999, 1998, and 1997, was $105.8 million, $83.2
million, and $54.9 million, respectively.

- -38-


Mortgage Loans, Unsecured Notes

Mortgage loans with maturities ranging from 2000 to 2013 are
collateralized by and in some instances cross-collateralized by
properties with a book value of $548.5 million.

As of December 31, 1999, $374.8 million in mortgage loans and $985.0
million in unsecured notes were outstanding. The interest rates on
$1,263.5 million of mortgage loans and unsecured notes are fixed and
range from 5.0% to 9.1%. Interest rates on $6.3 million of mortgage
loans float with a municipal bond index. The weighted average remaining
term for the mortgage loans and unsecured notes is 7.6 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(in thousands):

(1) The $75,000 of unsecured notes due 2013 is putable 2003.

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. This resulted in the recognition
of an extraordinary loss in 1997 of $2.9 million. This loss represented
the write-off of related deferred financing costs. 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 (7.43% at December 31, 1999). The rate
for the Credit Facility at December 31, 1998 was 6.67%. Customary fees
apply to the Credit Facility including an annual administrative fee and
an unused line fee. The Credit Facility matures on May 20, 2000. The
Company is in the process of negotiating a new credit facility.

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 distribution payment on the
Company's Common Shares. At the current $0.52 per Common Share per
quarter distribution payment rate, the effective interest rate on the
Convertible Debentures is 10.4%. At December 31, 1998, the effective
interest rate on the Convertible Debentures was 9.0%. In October 1999,
the Board of Trustees authorized a share repurchase plan under which the
Company may purchase up to $100 million of the Company's Common Shares
or its Convertible Debentures. In 1999, the Company repurchased $6.6
million principal amount of its Convertible Debentures. The repurchase
of the Convertible Debentures in 1999 resulted in the recognition of an
extraordinary loss in 1999 of $1.1 million. This loss represented the
redemption premium and the write-off of related deferred financing
costs. At December 31, 1999 and 1998, the Convertible Debentures were
convertible into 4,220,650 and 5,080,950 Common Shares, respectively.

The fair value of the Convertible Debentures at December 31, 1999 was
$104.5 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, 1999, 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 noncancelable
operating leases as of December 31, 1999 are as follows (in thousands):


2000 $ 333,739
2001 308,660
2002 252,204
2003 212,355
2004 170,339
Thereafter 514,908
----------
TOTAL $1,792,205
==========

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

7. SHAREHOLDERS' EQUITY

Common Shares

The Company paid to common shareholders and unitholders distributions of
$133.4 million, $109.4 million, and $70.6 million, during the years
ended December 31, 1999, 1998, and 1997, respectively. On a per share
basis, the Company paid Common Share distributions of $1.87, $1.71, and

- -40-


$1.65 during the years ended December 31, 1999, 1998, and 1997,
respectively.

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:

1999 1998 1997
------ ------ ------

Return of capital - - 30.4%
Ordinary income 100.0% 100.0% 68.4%
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.

Treasury Shares

In October 1999, the Board of Trustees authorized a share repurchase
plan under which the Company may purchase up to $100 million of the
Company's Common Shares or Convertible Debentures. In 1999, the Company
repurchased 59,100 of its Common Shares for $1.3 million.

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, $11.0
million, and $2.4 million during the years ended December 31, 1999, 1998
and 1997, respectively. On a per share basis, the Company paid
preferred share distributions of $2.20, $2.20, and $0.48 during the
years ended December 31, 1999, 1998, and 1997, respectively.

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:

1999 1998 1997
------ ------ ------

Return of capital - - -
Ordinary income 100.0% 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, certain
subsequent acquisitions, and the sale of preferred units. In connection
with the acquisition of properties for the year ended 1998, the Company
issued 1,049,846 common units. No common units were issued in
connection with acquisitions in 1999. The common limited partnership

- -41-


interests outstanding as of December 31, 1999 have the same economic
characteristics as would 4,884,221 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.

On July 28, 1999, the Company issued 3,800,000 Series B Cumulative
Redeemable Preferred Units of the Operating Partnership (the "Preferred
Units"). The Preferred Units are payable at the rate of 9.25% per annum
of the $25 liquidation preference. On or after July 28, 2004, the
Preferred Units may be redeemed for cash at the option of the Company.
The Preferred Units are exchangeable on a one-for-one basis at any time
on or after July 28, 2009 into Series B Cumulative Redeemable Preferred
Shares of the Trust.

The Company paid Preferred Unit distributions of $3.8 million during the
year ended December 31, 1999. On a per share basis, the Company paid
Preferred Unit distributions of $1.00 during the year ended December 31,
1999.

Shareholder Rights Plan

In December 1997, the Board of Trustees 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
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 to make a tender offer or exchange offer to acquire
beneficial ownership of Voting Stock that has 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. During the years ended December
31, 1999, 1998, and 1997, 367,263 Common Shares, 65,166 Common Shares,
and 13,293 Common Shares, respectively, were issued through 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

- -42-


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"), as amended,
has authorized the grant of options to executive officers, other key
employees, non-employee trustees and consultants of up to 6,500,000
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 1999, 1998, and 1997:

1999 1998 1997
------ ------ ------

Risk-free interest rate 6.6% 4.7% 5.5%
Dividend yield 8.4% 7.3% 6.0%
Volatility factor .174 .159 .155
Weighted-average expected life 8 years 8 years 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):
1999 1998 1997
--------- --------- --------
Pro forma income available to
common shareholders $129,317 $ 96,673 $ 55,538

Pro forma income per common share:

Basic $ 1.94 $ 1.58 $ 1.37
Diluted $ 1.94 $ 1.58 $ 1.36

- -43-


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, 1999, 1998, and 1997
follows:

Exercise prices for options outstanding as of December 31, 1999 ranged
from $19.75 to $26.95. The weighted-average remaining contractual life
of those options is 7.1 years.

An additional 2,580,168, 1,033,276, and 1,858,502 Common Shares were
reserved for issuance for future grants from the Share Incentive Plan at
December 31, 1999, 1998 and 1997, 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.

Although the Company is engaged in litigation incidental to its
business, there is no legal proceeding to which it is a party which, in
the opinion of management, will materially adversely affect the results
of the Company's operations.

11. SEGMENT INFORMATION

The Company 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; Lehigh Valley, Pennsylvania;
Virginia; the Carolinas; Jacksonville, Florida; Detroit, Michigan; and
all others combined (including Maryland; Tampa, Florida; South Florida;
Minneapolis, Minnesota; and the United Kingdom). The Company's
reportable segments are distinct business units which are each managed
separately in order to concentrate market knowledge within a
geographical area. Within these reportable segments, the Company
derives its revenues from its two product types: industrial properties
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 property
expenses and real estate taxes. The accounting policies of the
reportable segments are the same as those for the Company on a

- -45-


consolidated basis. The operating information by segment is as follows

12. PRO FORMA INFORMATION (UNAUDITED)

The following unaudited pro forma information has been prepared assuming
the common and preferred shares offerings which were consummated in 1997
and 1998 and the acquisitions of 170 properties acquired in 1997, and
137 properties acquired in 1998 had occurred at January 1, 1997. The
1997 acquisitions were acquired for a total investment of $727.9 million
and the 1998 acquisitions were acquired for a total investment of $580.2
million.

the Company had completed the common and preferred shares offerings and
completed the 1997 and 1998 acquisitions as of January 1, 1997, nor do
they purport to represent the results of operations of the Company for
future periods.

13. SUBSEQUENT EVENTS

In January 2000, under the Company's share repurchase plan, the
Company repurchased $3.8 million principal amount of its Convertible
Debentures. The repurchase of the Convertible Debentures will result in
the recognition of an extraordinary loss of $911,000. This loss
represents the redemption premium and write-off of related deferred
financing costs.

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 auditing standards generally
accepted in the United States. 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, 1999
and 1998, and the consolidated results of its operations and its cash
flows for each of the three years in the period ended December 31, 1999,
in conformity with accounting principles generally accepted in the
United States. 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 common equity
interest in the Operating Partnership of 93.2% at December 31, 1999.
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 accounting
principles generally accepted in the United States 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.

Reclassifications

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:

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

Expenditures directly related to development, acquisition, 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 indicators are present that affect the recovery of the

- -80-


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. As of December 31, 1999 and 1998, none of the
Company's assets was considered impaired.

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, 2001. 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, 1999 and 1998, the Company owned and operated industrial
and office properties located principally in suburban mixed-use

- -81-


developments or business parks. The carrying value of these properties
by type is as follows (in thousands):

Depreciation expense was $74.8 million in 1999, $61.7 million in 1998,
and $36.0 million in 1997.

As of December 31, 1999, the Company has commenced development on 22
properties, which upon completion are expected to comprise approximately
2.2 million square feet of leasable space. As of December 31, 1999
approximately $138.9 million has been expended for the development of
these projects and an additional $59.2 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, 1999, 1998, and 1997, the
fees for these services were $600,000 per year. The Company had accounts
and loan receivable from Rouse Kent Limited with balances of $5.1
million and $6.5 million as of December 31, 1999 and 1998, 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, 1999, 1998, and 1997, were
approximately 7.3%, 7.2%, and 7.5%, respectively. Interest expense for
the years ended December 31, 1999, 1998, and 1997, aggregated $99.7
million, $78.6 million, and $51.1 million, respectively. Interest costs
during these periods of $15.3 million, $16.3 million, and $11.8 million,
respectively, were capitalized. Cash paid for interest for the years
ended December 31, 1999, 1998, and 1997, was $105.8 million, $83.2
million, and $54.9 million, respectively.

Mortgage Loans, Unsecured Notes

Mortgage loans with maturities ranging from 2000 to 2013 are
collateralized by and in some instances cross-collateralized by
properties with a book value of $548.5 million.

As of December 31, 1999, $374.8 million in mortgage loans and $985.0
million in unsecured notes were outstanding. The interest rates on
$1,263.5 million of mortgage loans and unsecured notes are fixed and

- -82-


range from 5.0% to 9.1%. Interest rates on $6.3 million of mortgage
loans float with a municipal bond index. The weighted average remaining
term for the mortgage loans and unsecured notes is 7.6 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 (in thousands):

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

(1) The $75,000 of unsecured notes due 2013 is putable 2003.

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. This resulted in the recognition
of an extraordinary loss in 1997 of $2.9 million. This loss represented
the write-off of related deferred financing costs. 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 (7.43% at December 31, 1999). The rate for
the Credit Facility at December 31, 1998 was 6.67%. Customary fees
apply to the Credit Facility including an annual administrative fee and
an unused line fee. The Credit Facility matures on May 20, 2000. The
Company is in the process of negotiating a new credit facility.

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

- -83-


was 8.0% and increases with increases in the distribution payment on the
Company's Common Shares. At the current $.52 per Common Share per
quarter distribution payment rate, the effective interest rate on the
Convertible Debentures is 10.4%. At December 31, 1998, the effective
interest rate on the Convertible Debentures was 9.0%. In October 1999,
the Board of Trustees authorized a share repurchase plan under which the
Company may purchase up to $100 million of the Company's Common Shares
or Convertible Debentures. In 1999, the Company repurchased $6.6
million principal amount of its Convertible Debentures. The repurchase
of the Convertible Debentures in 1999 resulted in the recognition of an
extraordinary loss in 1999 of $1.1 million. This loss represented the
redemption premium and the write-off of related deferred financing
costs. At December 31, 1999 and 1998, the Convertible Debentures were
convertible into 4,220,650 and 5,080,950 Common Shares, respectively.

The fair value of the Convertible Debentures at December 31, 1999 was
$104.5 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, 1999, 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 noncancelable
operating leases as of December 31, 1999 are as follows (in thousands):

2000 $ 333,739
2001 308,660
2002 252,204
2003 212,355
2004 170,339
Thereafter 514,908
----------
TOTAL $1,792,205
==========

In addition to minimum rental payments, most leases require the tenants
to pay for their pro rata share of specified operating expenses. These
payments 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 "Series A Preferred Units"). All of the
Series A Preferred Units are held by the Trust. The Series A 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 Series A Preferred Units may be redeemed for cash at
the option of the Company.

On July 28, 1999, the Company issued 3,800,000 Series B Cumulative
Redeemable Preferred Units (the "Series B Preferred Units"). All of the
Series B Preferred Units are held by the Limited Partners. The Series B
Preferred Units are non-voting and have a liquidation preference of
$25.00 per unit and a preferential cash distribution rate of 9.25%. On
or after July 28, 2004, the Series B Preferred Units may be redeemed for
cash at the option of the Company. The Series B Preferred Units are

- -84-


exchangeable on a one-for-one basis at any time on or after July 28,
2009 into Series B Cumulative Redeemable Preferred Shares of the Trust.

8. 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.

Although the Company is engaged in litigation incidental to its
business, there is no legal proceeding to which it is a party which, in
the opinion of management, will materially adversely affect the results
of the Company's operations.

10. SEGMENT INFORMATION

The Company 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; Lehigh Valley, Pennsylvania;
Virginia; the Carolinas; Jacksonville, Florida; Detroit, Michigan; and
all others combined (including Maryland; Tampa, Florida; South Florida;
Minneapolis, Minnesota; and the United Kingdom). The Company's
reportable segments are distinct business units which are each managed
separately in order to concentrate 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 for the Company on a consolidated basis. The
operating information by segment is as follows (in thousands):
