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 contains statements that are or will
be forward-looking, such as statements relating to business development
and development activities, acquisitions, 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,
acquisitions, dispositions, 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 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,
the potential adverse impact of market interest rates on the market price
for the Company's securities.

                       LIBERTY PROPERTY LIMITED PARTNERSHIP

               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

                                   JUNE 30, 2000

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, 1999. 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 restated 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 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 93.4% at June 30, 2000.  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 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.

                                -16-


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 and six months ended June 30, 2000 (unaudited) with
the results of operations of the Company for the three and six months
ended June 30, 1999 (unaudited).  As a result of the development,
acquisition and disposition activities by the Company in 2000 and 1999,
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 and six months ended June 30, 2000 compared to the three
and six months ended June 30, 1999.
- -----------------------------------------------------------------------

Total revenue (principally rental revenue and operating expense
reimbursement) increased to $131.0 million from $115.2 million for the
three months ended June 30, 2000 compared to the same period in 1999, and
increased to $260.0 million from $227.4 million for the six months ended
June 30, 2000 as compared to the same period in 1999.  These increases
are primarily due to the increase in the number of properties in
operation during the respective periods.  As of June 30, 1999, the
Company had 627 properties in operation and, as of June 30, 2000, the
Company had 649 properties in operation. From January 1, 1999 through
March 31, 1999 and from April 1, 1999 through June 30, 1999 the Company
completed the development on or acquired 19 properties and 15 properties,
respectively, for Total Investments (as defined below) of approximately
$71.2 million and $120.0 million, respectively.  From January 1, 2000
through March 31, 2000 and from April 1, 2000 through June 30, 2000, the
Company completed the development on or acquired 15 properties and seven
properties, respectively, for Total Investments of approximately $130.7
million and $53.0 million, respectively. Offsetting the increases in the
number of properties developed and acquired and the related Total
Investments during the periods were property dispositions. From January
1, 1999 through March 31, 1999, and from April 1, 1999 through June 30,
1999, the Company sold two and 14 properties, respectively, for
approximately $8.7 million and $51.3 million, respectively.  From January
1, 2000 through March 31, 2000, and from April 1, 2000 through June 30,
2000, the Company sold three and three properties, respectively, for
approximately $30.2 million and $10.5 million, respectively.
Additionally, during the periods from January 1, 2000 through March 31,
2000 and from April 1, 2000 through June 30, 2000, the Company sold one
and two parcels of land for approximately $1.4 million and $7.9 million,
respectively.  There were no land sales during the six months ended June
30, 1999.  The "Total Investment" for a property is defined as the
property's purchase price plus closing costs and management's estimate,
as determined at the time of acquisition, of the cost of necessary
building improvements in the case of acquisitions, or land costs and land
and building improvement costs in the case of development projects, and
where appropriate, other development costs and carrying costs required to
reach rent commencement.

Rental property and real estate tax expenses increased to $35.7 million
from $30.7 million for the three months ended June 30, 2000 compared to

                                -20-


the same period in 1999, and to $72.8 million from $61.7 million for the
six months ended June 30, 2000 compared to the same period in 1999. This
increase is due to the increase in the number of properties owned during
the respective periods.

Property-level operating income for the "Same Store" properties
(properties owned as of January 1, 1999) increased to $156.1 million for
the six months ended June 30, 2000 from $151.7 million for the six months
ended June 30, 1999, with straightlining (which recognizes rental revenue
evenly over the life of the lease), and increased to $153.0 million for
the six months ended June 30, 2000 from $148.6 million for the six months
ended June 30, 1999, without straightlining.  These increases of 3.0% are
due to increases in the rental rates for the properties.

Set forth below is a schedule comparing the property-level operating
income for the "Same Store" properties for the six months ended June 30,
2000 and 1999 (in thousands).

General and administrative expenses increased to $4.8 million for the
three months ended June 30, 2000 from $3.9 million for the three months
ended June 30, 1999, and to $9.3 million for the six months ended June
30, 2000 from $7.9 million for the six months ended June 30, 1999.  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.

Depreciation and amortization expense increased to $22.8 million for the
three months ended June 30, 2000 from $20.4 million for the three months
ended June 30, 1999, and to $45.5 million for the six months ended June
30, 2000, from $40.6 million for the six months ended 1999.  This
increase is due to an increase in the number of properties owned during
the respective periods.

Interest expense increased to $26.4 million for the three months ended
June 30, 2000 from $25.8 million for the three months ended June 30,
1999, and to $52.0 million for the six months ended June 30, 2000 from
$49.6 million for the six months ended 1999.  These increases are due to
an increase in the average debt outstanding for the respective periods
which was $1,564.3 million for the three months ended June 30, 2000
compared to $1,497.2 million for the three months ended June 30, 1999,
and $1,540.0 million for the six months ended June 15, 2000 compared to
$1,472.7 million for the six months ended June 30, 1999.  In addition,
the weighted average interest rates for the respective periods have
increased from 7.24% for the six months ended June 30, 1999 to 7.53% for

                                -21-


the six months ended June 30, 2000, and from 7.23% for the six months
ended June 30, 1999 to 7.52% for the six months ended June 30, 2000.

In the second quarter of 2000, the Company realized a gain on sale of
$4.4 million, due to the sale of three properties and two parcels of land
for $18.4 million, and during the six months ended June 30, 2000 the
Company realized a gain on sale of $8.7 million, due to the sale of six
properties and three parcels of land for $50.0 million.  In the second
quarter of 1999, the Company realized a gain on sale of $11.9 million,
due to the sale of 14 properties for $51.3 million, and during the six
months ended June 30, 1999 the Company realized a gain on sale of $13.2
million, due to the sale of 16 properties for $60.0 million.

In the second quarter of 2000, the Company repurchased $1.2 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 second quarter of 2000
totaling $228,000.  During the six months ended June 30, 2000, the
Company repurchased $10.9 million principal amount of the Exchangeable
Subordinated Debentures due 2001.  This resulted in the recognition of
an extraordinary loss in the six months ended June 30, 2000 totaling $2.1
million.  These losses represent the redemption premium and the write-off
of related deferred financing costs.  There were no extraordinary items
in the six months ended June 30, 1999.

As a result of the foregoing, the Company's income before minority
interest decreased to $45.6 million for the three months ended
June 30, 2000 from $46.3 million for the three months ended June 30,
1999, and increased to $87.1 million for the six months ended June 30,
2000 from $80.9 million for the six months ended June 30, 1999.  In
addition, net income decreased to $40.3 million for the three months
ended June 30, 2000 from $43.3 million for the three months ended June
30, 1999, and increased to $77.2 million for the six months ended June
30, 2000 from $75.7 million for the six months ended June 30, 1999.

LIQUIDITY AND CAPITAL RESOURCES

As of June 30, 2000, the Company had cash and cash equivalents of $4.7
million.

Net cash flow provided by operating activities decreased to $120.0
million for the six months ended June 30, 2000 from $131.2 million for
the six months ended June 30, 1999.  This $11.2 million decrease was
primarily due to the fluctuations in accounts payable and prepaid
expenses and other assets during the respective periods.

Net cash used in investing activities increased to $133.8 million for the
six months ended June 30, 2000 from $128.4 million for the six months
ended June 30, 1999.  This increase primarily resulted from an increase
in land held for development and decreased disposition activity in 2000.

Net cash provided by financing activities decreased to $9.4 million for
the six months ended June 30, 2000 from $16.4 million for the six months
ended June 30, 1999. This decrease is primarily due to the retirement of
convertible debentures.

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

The Company funds its acquisitions and completed development with long-
term capital sources.  In the six months ended June 30, 2000, these

                               -22-

activities were funded on a temporary basis through a $325.0 million
unsecured line of credit (the "$325 Million Credit Facility"), which was
replaced in April 2000.

In April 2000, the Company increased its borrowing capacity and obtained
a new $450 million unsecured revolving credit facility (the "$450 Million
Credit Facility") replacing the $325 Million Credit Facility and a $90
million term loan due January 2001 (the "$90 Million Term Loan").

The interest rate on borrowings under the $450 Million 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, as of July 31, 2000, the interest rate
for borrowings under the $450 Million Credit Facility is 115 basis points
over LIBOR.

As of June 30, 2000, $370.3 million in mortgage loans and $895.0 million
in unsecured notes were outstanding.  The interest rates on $1,259.0
million of mortgage loans and unsecured notes are fixed and range from
5.0% to 9.1%.  The interest rates on $6.3 million of mortgage loans float
with LIBOR or a municipal bond index, none of which is subject to a cap.
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 June
30, 2000 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
expects to incur variable rate debt, including borrowings under the $450
Million Credit Facility, from time to time.

                                -23-


In 1999, the Company received approximately $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 approximately $246.0 million in aggregate net proceeds
from the issuance of unsecured notes. 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.  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 October 1999, the Board of Trustees authorized a share repurchase
program.  Pursuant to the Plan, the Company may purchase up to $100
million of the Company's Common Shares, Convertible Debentures or
Preferred Shares. Through July 31, 2000, 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.

The Company has an effective S-3 shelf registration statement on file
with the Securities and Exchange Commission.  As of July 31, 2000, 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 $508.0 million in debt securities.

In April 2000, the Company obtained a new, three year, $450 million
unsecured revolving credit facility replacing a $325 million unsecured
revolving credit facility due May 2000 and a $90 million term loan
January 2001.  The interest rate for the loan, as of July 31, 2000, is
115 basis points over LIBOR.


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), 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
generally accepted accounting principles 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

                                 -24-


generally accepted accounting principles.  Funds from operations for the
three and six months ended June 30, 2000 and June 30, 1999 are as follows

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 $450 Million Credit Facility bears interest at a variable
rate; therefore, the amount of interest payable under the $450 Million
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.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
- -------------------------------------------------------------------

There have been no material changes to the Company's exposure to market
risk since its Annual Report on Form 10-K for the year ended December 31,
1999.

PART II: OTHER INFORMATION
- --------------------------

Item 1.  Legal Proceedings

         None

Item 2.  Changes in Securities and Use of Proceeds

         On April 18, 2000, the Operating Partnership issued 800,000
9.125% Series C Cumulative Redeemable Preferred Units of Limited
Partnership Interest (the "Units").  The aggregate sale price of the
Units was $20.0 million.  The Units were sold to an institutional
investor in a private placement in reliance on the exemption from
registration under Section 4(2) of the Securities Act of 1933, as
amended.  The Units are convertible after ten years (or, under limited
circumstances, a shorter period of time), on a one-for-one basis, into
the 9.125% Series C Cumulative Redeemable Preferred Shares of Beneficial
Interest of the Trust (the "Preferred Shares"), which were authorized
for issuance by the Trust in connection with this transaction.  The
Units have identical rights, preferences and privileges as the Preferred
Shares.  The Units do not include any mandatory redemption or sinking
fund provisions.  The holders of the Units have certain rights to cause
the Trust to register the Preferred Shares pursuant to the terms of a
registration rights agreement entered into in connection with this
private placement.

         The aggregate net proceeds of the sale of the Units,
approximately $19.5 million, were used to repay the borrowings under the
$325 Million Credit Facility.

         In connection with the sale of the Units, the Operating
Partnership amended its Second Restated and Amended Agreement of Limited
Partnership, as amended, pursuant to the Second Amendment thereto, filed
as Exhibit 3.1.1 to this Report.  The Articles Supplementary to the
Amended and Restated Declaration of Trust of the Trust creating the
Preferred Shares are filed as Exhibit 3.1.2 to this Report.

         The Units are pari passu with the 8.80% Series A Cumulative
Redeemable Preferred Units of Limited Partnership and the 9.25% Series B
Cumulative Redeemable Preferred Units of Limited Partnership of the
Operating Partnership, and senior to all other units of limited
partnership interest of the Operating Partnership.  The Preferred Shares
are pari passu with the 8.80% Series A Cumulative Redeemable Preferred
Shares of Beneficial Interest and the 9.25% Series B Cumulative
Redeemable Preferred Shares of Beneficial Interest of the Trust, and
senior to the Common Shares of Beneficial Interest of the Trust.
