- -----------------------------
The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for forward-looking statements. Certain information included in
this Quarterly Report on Form 10-Q 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 real estate development activities,
acquisitions,  dispositions, future capital expenditures, financing
sources and availability, and the effects of regulation (including
environmental regulation) and competition.  Although Liberty Property
Trust and Liberty Property Limited Partnership (together, the "Company")
believe that the expectations reflected in such forward-looking
statements are based on reasonable assumptions, it can give no assurance
that its expectations will be achieved.  As forward-looking statements,
these statements involve important risks, uncertainties and other factors
that could cause actual results to differ materially from the expected
results and, accordingly, such results may differ from those expressed in
any forward-looking statements made by, or on behalf of the Company.
These risks, uncertainties and other factors include, without limitation,
uncertainties affecting real estate businesses generally (such as entry
into new leases, renewals of leases and dependence on tenants' business
operations), risks relating to our ability to maintain and increase
property occupancy and rental rates, 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), 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.   The Company assumes no
obligation to update or supplement forward-looking statements that become
untrue because of subsequent events.

accounting principles generally accepted in the United States ("US GAAP")
for interim financial information and with the instructions to Form 10-Q
and Article 10 of Regulation S-X. Accordingly, they do not include all of

(consisting solely of normal recurring adjustments) necessary for a fair

Diluted income per common share as of March 31, 2001 includes the
weighted average common shares, the dilutive effect of the outstanding

   8

options and the dilutive effect of the conversion of the Exchangeable
Subordinate Debentures due 2001 of the Operating Partnership (the
"Convertible Debentures"), into common shares.  Diluted income per common
share as of March 31, 2000 includes the weighted average common shares
and the 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.

NOTE 2 - ORGANIZATION
- ---------------------

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 the Operating
Partnership.  The Trust is the sole general partner and also a limited
partner of the Operating Partnership, owning 94.6% of the common equity
of the Operating Partnership at March 31, 2001.  The Company provides
leasing, property management, development, acquisition, 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.

NOTE 3 - 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
consolidated basis.

The operating information by segment is as follows (in thousands):

                       LIBERTY PROPERTY LIMITED PARTNERSHIP

               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

                                MARCH 31, 2001

NOTE 1 - BASIS OF PRESENTATION
- ------------------------------

The accompanying unaudited consolidated financial statements of Liberty
Property Limited Partnership (the "Operating Partnership") and its direct
and indirect subsidiaries have been prepared in accordance with
accounting principles generally accepted in the United States ("US GAAP")
for interim financial information and with the instructions to Form 10-Q
and Article 10 of Regulation S-X. Accordingly, they do not include all of
the information and footnotes required by US GAAP for complete financial
statements and should be read in conjunction with the consolidated
financial statements and notes thereto included in the Annual Report on
Form 10-K of the Trust and the Operating Partnership for the year ended
December 31, 2000. In the opinion of management, all adjustments
(consisting solely of normal recurring adjustments) necessary for a fair
presentation of the financial statements for these interim periods have
been included. The results of interim periods are not necessarily
indicative of the results to be obtained for a full fiscal year.  Certain
amounts from prior periods have been reclassified to conform to current
period presentation.

NOTE 2 - 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 the Operating Partnership (the Trust, Operating
Partnership and their respective subsidiaries referred to collectively as
the "Company").  The Trust is the sole general partner and also a limited
partner of the Operating Partnership, owning 94.6% of the common equity
of the Operating Partnership at March 31, 2001.  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.

NOTE 3 - 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.

   14

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
consolidated basis.  The operating information by segment is as follows
(in thousands):

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 three months ended March 31, 2001 (unaudited) with the
results of operations of the Company for the three months ended March 31,
2000 (unaudited).  As a result of the development, acquisition and
disposition activities by the Company in 2001 and 2000, 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.  As used herein, the
term "Company" includes the Trust, the Operating Partnership and their
subsidiaries.

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

For the three months ended March 31, 2001 compared to the three months
ended March 31, 2000.
- -----------------------------------------------------------------------

Total revenue (principally rental revenue and operating expense
reimbursement) increased to $145.6 million from $129.0 million for the
three months ended March 31, 2001 compared to the same period in 2000.
This increase is primarily due to the increase in the number of
properties in operation during the respective periods.  As of March 31,
2001, the Company had 660 properties in operation compared to 645
properties at March 31, 2000.  The following is a summary of the
Company's acquisition, development and disposition activity for the three
months ended March 31, 2001 and 2000:

(1) 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.


Additionally, during the period from January 1, 2001 through March 31,
2001, the Company sold two parcels of land for approximately $1.2
million.  From January 1, 2000 through March 31, 2000, the Company sold
one parcel of land for approximately $1.6 million.

Rental property and real estate tax expenses increased to $42.6 million
from $37.1 million for the three months ended March 31, 2001 compared to
the same period in 2000. This increase is due to the increase in the
number of properties owned during the respective periods, and an increase
in snow removal and other seasonal operating costs during the severe 2001
winter compared to the mild 2000 winter.

Property-level operating income for the "Same Store" properties
(properties owned as of January 1, 2000) increased to $90.0 million for
the three months ended March 31, 2001 from $85.8 million for the three
months ended March 31, 2000, on a straight line basis (which recognizes
rental revenue evenly over the life of the lease), and increased to $88.1
million for the three months ended March 31, 2000 from $83.5 million for
the three months ended March 31, 2000, on a cash basis.  These increases
of 4.9% and 5.5%, respectively, are primarily due to increases in rental
rates for the properties and also due to increases in occupancy.

Set forth below is a schedule comparing the property-level operating
income for the "Same Store" properties for the three months ended March
31, 2001 and 2000 (in thousands).

General and administrative expenses increased to $5.8 million for the
three months ended March 31, 2001 from $4.4 million for the three months
ended March 31, 2000.  This 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, and the
funding of initiatives which the Company undertook relating to training,
internal assurance, property management, and marketing.

   18

Depreciation and amortization expense increased to $24.9 million for the
three months ended March 31, 2001 from $22.6 million for the three months
ended March 31, 2000.  This increase is due to an increase in the number
of properties owned during the respective periods.

Interest expense increased to $27.8 million for the three months ended
March 31, 2001 from $25.7 million for the three months ended March 31,
2000.  This increase is due to an increase in the average debt
outstanding for the respective periods, which was $1,724.7 million for
the three months ended March 31, 2001 compared to $1,528.2 million for
the three months ended March 31, 2000.  In addition, the weighted average
interest rates for the respective periods have increased from 7.33% for
the three months ended March 31, 2000 to 7.60% for the three months ended
March 31, 2001.

In the first quarter of 2001, the Company realized a gain on sale of $1.5
million, due to the sale of two properties, one development property and
two parcels of land for $13.6 million.  In the first quarter of 2000, the
Company realized a gain on sale of $4.4 million, due to the sale of three
properties and one parcel of land for $31.6 million.

During the three months ended March 31, 2000, the Company repurchased
$9.8 million principal amount of the Exchangeable Subordinated Debentures
due 2001 of the Operating Partnership (the "Convertible Debentures").
This resulted in the recognition of an extraordinary loss in the three
months ended March 31, 2000 totaling $1.9 million.  This loss represents
the redemption premium and the write-off of related deferred financing
costs.  There were no extraordinary items during the first quarter of
2001.

As a result of the foregoing, the Company's income before minority
interest increased to $45.9 million for the three months ended
March 31, 2001 from $41.5 million for the three months ended March 31,
2000.  In addition, net income increased to $41.1 million for the three
months ended March 31, 2001 from $36.9 million for the three months ended
March 31, 2000.

LIQUIDITY AND CAPITAL RESOURCES

As of March 31, 2001, the Company had cash and cash equivalents of $3.4
million.

Net cash flow provided by operating activities increased to $89.5
million for the three months ended March 31, 2001 from $49.2 million for
the three months ended March 31, 2000.  This $40.3 million increase was
primarily due the increase in net income and to the fluctuations in
prepaid expenses during the respective periods.

Net cash used in investing activities increased to $111.0 million for the
three months ended March 31, 2001 from $87.2 million for the three months
ended March 31, 2000.  This increase primarily resulted from an increase
in development in progress and decreased disposition activity in 2001.

Net cash provided by financing activities decreased to $20.3 million for
the three months ended March 31, 2001 from $32.1 million for the three
months ended March 31, 2000.  This decrease is primarily due to the pay
down of the Credit Facility in 2001 with the proceeds from an unsecured
notes issuance and the funding of investing activities with the increased
funds provided by operations.

   19

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

The Company funds its acquisitions and completed developments with long-
term capital sources.  During the three months ended March 31, 2001,
these activities were funded through a $450 million unsecured line of
credit (the "Credit Facility").  This facility was obtained in April
2000, replacing a $325 million unsecured line of credit and a $90 million
term loan due January 2001.

The interest rate on borrowings under the Credit Facility fluctuates
based upon the Company's leverage levels or ratings from Moody's
Investors Services, Inc. ("Moody's") and Standard & Poor's Ratings Group
("Standard & Poor's"). Moody's and Standard & Poor's currently assign
senior debt ratings to the Company of Baa3 and BBB, respectively.  At
these ratings the interest rate for borrowings under the Credit Facility
is 115 basis points over LIBOR.

As of March 31, 2001, $357.2 million in mortgage loans and $1,345.0
million in unsecured notes were outstanding.  The interest rates on
$1,696.2 million of mortgage loans and unsecured notes are fixed and
range from 6.0% to 8.8%.  The interest rate on a $6.0 million mortgage
loan floats with a municipal bond index. The weighted average remaining
term for the mortgage loans and the unsecured notes is 7.6 years. The
scheduled maturities of principal amortization of the Company's mortgage
loans and the unsecured notes outstanding and the related weighted
average interest rates as of March 31, 2001 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 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

Credit Facility, from time to time.

In 2000, the Company received approximately $19.5 million in aggregate
net proceeds from the issuance of 9.125% Series C Cumulative Redeemable
Preferred Units, and approximately $197.1 million in aggregate net
proceeds from the issuance of unsecured notes.  In 2001, the Company
received approximately $246.2 million in aggregate net proceeds from the
issuance of unsecured notes.  The Company used the aggregate net proceeds
from issuance of the preferred units, and unsecured notes to fund the
Company's activities, including paying down the Credit Facility, which
funds development and acquisition activity.

In October 1999, the Board of Trustees authorized a share repurchase
program.  Pursuant to the Plan, as amended, the Company may purchase up
to $100 million of the Company's Common Shares, Convertible Debentures or
Preferred Shares.  Through May 4, 2001, the Company purchased 59,100
Common Shares and purchased Convertible Debentures exchangeable into
877,950 Common Shares. The total cost for the purchase of the Common
Shares and Convertible Debentures was approximately $21.9 million.

with the Securities and Exchange Commission.  As of May 4, 2001, the
Company had the capacity pursuant to this shelf registration statement to
issue $688.4 million in equity securities and the Operating Partnership
had the capacity to issue $261.1 million in debt securities.

CALCULATION OF FUNDS FROM OPERATIONS

Management generally considers Funds from operations (as defined below) a
useful financial performance measure of the operating performance of an
equity REIT, because, together with net income and cash flows, Funds from
operations provides investors with an additional basis to evaluate the
ability of a REIT to incur and service debt and to fund development,
acquisitions and capital expenditures.  Funds from operations is defined
by NAREIT as net income (computed in accordance with generally accepted
accounting principles ("GAAP")), excluding gains (or losses) from sales
of property, plus depreciation and amortization, and after adjustments
for unconsolidated partnerships and joint ventures.  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 three months ended March 31, 2001 and March 31, 2000
are as follows (in thousands):

INFLATION
- ---------

Inflation has remained relatively low during the last three years, and as
a result, it has not had a significant impact on the Company during this
period. The Credit Facility bears interest at a variable rate; therefore,
the amount of interest payable under the Credit Facility 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 and 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.
