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

PART I 
 
ITEM 1. BUSINESS
- ---------------- 
 
THE COMPANY 
 
Liberty Property Trust (the "Trust") is a self-administered and self-
managed Maryland real estate investment trust (a "REIT"). Substantially 
all of the Trust's assets are owned directly or indirectly, and 
substantially all of the Trust's operations are conducted directly or 
indirectly, by its subsidiary, Liberty Property Limited Partnership, a 
Pennsylvania limited partnership (the "Operating Partnership" and, 
together with the Trust and its consolidated subsidiaries, the 
"Company").  The Company was formed to continue and expand the 
commercial real estate business of Rouse & Associates, a Pennsylvania 
general partnership, and certain affiliated entities (collectively, the 
"Predecessor").  Founded in 1972, the Predecessor developed and managed 
commercial real estate in the Southeastern, Mid-Atlantic and West Coast 
markets.
 
The Company provides leasing, property management, acquisition,  
development, construction management, design management and other  
related services for a portfolio which, as of December 31, 1998,  
consisted of 608 industrial and office properties (the "Properties in  
Operation") totalling approximately 44.2 million leaseable square feet. 
As of December 31, 1998, the Properties in Operation were approximately 
95.0% leased to over 1,900 tenants.  As of December 31, 1998, the 
Company also had 45 properties under development (the "Properties Under 
Development" and, together with the Properties in Operation, the 
"Properties"). The Properties Under Development are expected to 
generate, upon completion, approximately four million leaseable square 
feet. The Properties are located principally within the Southeastern, 
Mid-Atlantic and Midwestern United States.  As of December 31, 1998, the 
Company also owned 1,113 acres of land, all zoned for commercial use, 
which the Company anticipates are capable of supporting, as and when 
developed, approximately nine million leaseable square feet.
 
During the year ended December 31, 1998, through Total Investments (as  
defined below) aggregating $863.6 million, the Company increased its 
total leaseable square footage of industrial and office space  
approximately 36.1% by acquiring 144 properties totalling approximately 
8.6 million leaseable square feet and by developing 34 properties 
totalling approximately 3.5 million leaseable square feet.  The "Total 
Investment" for a property is defined as the property's purchase price 
plus closing costs and management's estimate, as determined at the time 
of acquisition, of the cost of necessary building improvements in the 
case of acquisitions, or land costs and land and building improvement 
costs in the case of development projects, and, where appropriate, other 
development costs and carrying costs required to reach rent 
commencement.

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

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

- -5-
<PAGE>
properties are located in suburban, mixed-use developments or business 
parks.  They include both single-tenant and multi-tenant facilities, 
with most designed flexibly to accommodate various types of tenants, 
space requirements and industrial uses in an effort to increase re-
leasing opportunities and control re-leasing costs.  The Company's 
office properties are mid-rise and single-story office buildings, 
located principally in suburban mixed-use developments or office parks.  
Substantially all of the Company's properties are located in prime 
business locations within established business communities offering 
excellent access to interstate highway systems.
 
The Trust is the sole general partner and also a limited partner of the  
Operating Partnership, with a combined equity interest in the Operating  
Partnership of 92.6% at December 31, 1998.  The units of limited 
partnership interest in the Operating Partnership (the "Units") are 
exchangeable on a one-for-one basis (subject to antidilution 
protections) for the Common Shares of Beneficial Interest, $0.001 par 
value per share (the "Common Shares"), of the Trust, typically after the 
first anniversary of the issuance of any such Units.  The only limited 
partners of the Operating Partnership other than the Trust are persons 
or entities that contributed assets to the Operating Partnership and 
received Units in exchange therefor.  The Units held by the limited 
partners other than the Trust (that is, the minority interest reflected 
in the Trust's financial statements) were exchangeable for approximately 
5.2 million Common Shares on December 31, 1998.  Certain holders of 
Units issued in connection with the contribution of assets to the 
Operating Partnership have the right to require the Company to register 
the issuance or resale of the Common Shares underlying their Units upon 
exchange for the Units, in order to afford such holders liquidity with 
respect to their investment.
 
The Company's executive offices are located at 65 Valley Stream Parkway, 
Malvern, Pennsylvania 19355.  The telephone number is (610) 648-1700.   
The Company maintains offices in each of its principal markets.  As of 
December 31, 1998 the Company's principal markets were as follows: 
Southeastern Pennsylvania; New Jersey/Delaware; Lehigh Valley, 
Pennsylvania; Maryland; Virginia; the Carolinas; Jacksonville, Florida; 
Tampa, Florida; South Florida;  Minneapolis, Minnesota; Detroit, 
Michigan; and the United Kingdom.  Additionally, the Company owns and 
operates properties in the Orlando, Florida and Milwaukee, Wisconsin 
markets.  For further detail regarding the Company's properties in 
particular markets, please refer to Item 2. Properties and Notes 11 and 
10 of the Notes to the Liberty Property Trust and the Liberty Property 
Limited Partnership Financial Statements, respectively. 
 
MANAGEMENT AND EMPLOYEES 
 
The Company's 331 employees (as of February 22, 1999) are under the 
direction of 19 senior executives, who have developed and managed 
commercial real estate during the past 26 years and who, on average, 
have been affiliated with the Company and/or the Predecessor for 13 
years. The Company's in-house leasing, marketing and property management 
staff operates in full-service local offices in markets where it has a 
significant presence.  This structure enables the Company to better 
understand the particular characteristics of the local markets in which 
it operates, to respond quickly and directly to tenant needs and to 
better identify local development and acquisition opportunities.  The 
Company considers its relations with its employees to be good.

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

INTERNAL GROWTH STRATEGIES 
 
Management believes that the Properties offer significant opportunities  
for the Company to increase its rental revenues and cash flow over the 
long term.  The Company seeks to increase cash flow by continuing its 
practice of negotiating for annual contractual rental increases that 
take effect during the terms of its leases.  In addition, the Company 
seeks to increase rental revenues through the renewal or replacement of 
expiring leases at rental rates which are higher than the rates under 
expiring leases and by improving the occupancy rates of its portfolio.  
Finally, the Company intends to maximize earnings through controlling 
costs. 
 
NEW LEASES AND LEASE RENEWALS. In the past year, the Company generally 
has been experiencing increases in rental rates in replacement and 
renewal leases.  Although no assurance can be given, the Company expects 
that in the near term, replacement and renewal leases will continue to 
reflect rental rates which are higher than the rates under expiring 
leases.
 
CONTRACTUAL INCREASES.  The Company seeks to generate increased cash 
flow from the Properties in Operation through annual contractual 
increases in rental rates under its leases.  The leases in effect with 
respect to the Properties in Operation as of December 31, 1998 provide 
for contractual rental increases that are expected to contribute an 
additional $5.0 million to the Company's cash flow for the year ending 
December 31, 1999.  The Company intends to continue seeking to negotiate 
annual contractual rent increases that take effect during the terms of 
its leases. 
 
MAINTAINING HIGH OCCUPANCIES.  The Company believes that the quality and 
diversity of its tenant base and its strategy of operating in multiple 
markets has contributed, and will continue to contribute, to its success 
in obtaining increases in rental rates and maintaining high occupancy 
levels.  The Company targets financially stable tenants in an effort to 
minimize uncertainty relating to the ability of its tenants to meet 
their lease obligations.
 
COST CONTROLS.  The Company monitors and controls its operating and 
administrative costs by performing many functions in-house rather than 
by engaging outside third parties. For example, although construction 
and design services typically are provided by third parties, the 
Company's in-house construction and design management staff closely 
supervises construction and design activities in an effort to control 
costs, minimize cost overruns, ensure timely delivery of tenant space 
and maximize productivity and efficiencies.  The Company also employs an 
annual capital improvement and preventive maintenance program designed 
to reduce the operating costs of the Properties and maintain long-term 
values.

<PAGE>

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

COMPLETED PROPERTY DEVELOPMENTS.  During the year ended December 31, 
1998, the Company completed 12 build-to-suit and 22 inventory  
projects, totalling approximately 3.5 million square feet of leaseable 
space and representing an aggregate Total Investment of approximately 
$237.3 million.  As of December 31, 1998, these completed development 
properties were 94.5% leased. 
 
PROPERTIES UNDER DEVELOPMENT.  As of December 31, 1998, the Company had 
45 Properties Under Development in 11 markets which, upon completion, 
are expected to generate approximately four million leaseable square 
feet.  Approximately 56.8% of such leaseable space was pre-leased as of 
December 31, 1998.  The Properties Under Development as of December 31, 
1998 are expected to represent a Total Investment of $367.8 million.  
Six of these properties are 100% pre-leased under net leases as build-
to-suit projects. The Company is scheduled to complete development of 30 
properties (totalling approximately 2.9 million leaseable square feet) 
in the year ending December 31, 1999 representing a Total Investment of 
$229.0 million. 
 
ACQUISITIONS 

STRATEGY

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

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

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

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

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

- -8-
<PAGE>

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

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

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

INTERNATIONAL OPERATION.  The Company's international operation includes 
five Properties in Operation in the County of Kent, England.  In 
addition, the Company provides management services with respect to a 
joint venture between Rouse Kent Limited, which is owned by certain 
senior executives of the Company, and the County of Kent, England to 
develop a 650-acre, mixed-use park approximately 25 miles southeast of 
London.  The Company has an option to purchase Rouse Kent Limited for 
nominal consideration.  The Company has a loan receivable from Rouse 
Kent Limited at December 31, 1998, with an outstanding balance of $5.9 
million.  
 
SUBSEQUENT ACTIVITIES 
 
Since December 31, 1998, and through February 22, 1999, the Company has 
completed development of seven industrial and office properties 
containing approximately 415,000 leaseable square feet for a Total 
Investment of $23.2 million.  In addition, during such period the 
Company has purchased seven industrial and office properties containing 
approximately 275,000 leaseable square feet for a Total Investment of 
$26.3 million. 

On January 15, 1999 the Company closed a $135 million, two-year 
unsecured term loan.  The interest rate for the loan is 135 basis points 
over LIBOR.
 
The Company intends to continue to pursue its development and 
acquisition strategies.  The Company is currently in various stages of 
discussions and negotiations with respect to development and acquisition 
projects with a Total Investment of approximately $150.0 million.  The 

- -9-
<PAGE>
consummation of these or any other future developments or acquisitions, 
if any, and the pace at which developments may be completed and 
acquisitions made, cannot be assured. 
 
COMPETITION 
 
The Company faces competition as a lessor, buyer, and developer of 
properties and will likely face competition as a seller of  
properties to the extent that properties are sold.  The Company believes 
that its responsiveness to tenant needs will enable it to attract and 
retain high quality tenants in the markets in which the Properties in 
Operation are located. However, the number of competitive properties in 
any particular market in which the Company's Properties are located 
could have a material adverse effect on both the Company's ability to 
lease space and on rental rates at the Properties.  There are numerous 
other entities, including but not limited to other REITs, that compete 
with the Company in seeking to acquire the limited number of properties 
available for sale that meet the Company's criteria. However, the 
Company believes that its management, its capital base, its existing 
sources of credit and its access to capital will provide the Company 
with competitive advantages.
 
ENVIRONMENTAL REGULATIONS 
 
Under various federal, state and local laws, ordinances and regulations  
relating to the protection of the environment (collectively,  
"Environmental Laws"), a current or previous owner or operator of real  
estate may be liable for the cost of removal or remediation of certain  
hazardous or toxic substances disposed, stored, released, generated,  
manufactured or discharged from, on, at, onto, under or in such  
property.  Environmental Laws often impose such liability without regard 
to whether the owner or operator knew of, or was responsible for, the  
presence or release of such hazardous or toxic substances.  In addition, 
the presence of any such substances or the failure to properly remediate 
such substances when present, released or discharged may adversely  
affect the owner's ability to sell or rent such property or to borrow  
using such property as collateral.  The cost of any required remediation  
and the liability of the owner or operator therefore as to any property  
is generally not limited under such Environmental Laws and could exceed  
the value of the property and/or the aggregate assets of the owner or  
operator.  Persons who arrange for disposal of hazardous or toxic  
substances may also be liable for the costs of removal or remediation of  
such substances at a disposal or treatment facility, whether or not such  
facility is owned or operated by such persons.  In addition to any  
action required by federal, state or local authorities, the presence of  
hazardous or toxic substances on any of the Properties, or on any  
properties acquired hereafter, could result in private plaintiffs  
bringing claims for personal injury or other causes of action.  In  
connection with the ownership and operation of the Properties, and with 
respect to any properties acquired hereafter, the Company may be 
potentially liable for remediation, release or injury.  Further, various 
Environmental Laws impose on owners or operators the requirement of 
ongoing compliance with rules and regulations regarding business-related 
activities that may affect the environment.  Failure to comply with such 
requirements could result in difficulty in the lease or sale of any 
affected Property or the imposition of monetary penalties and fines in 
addition to the costs required to attain compliance. 
 
All of the Properties and land have been subject to Phase I  
Environmental Assessments ("Phase I Assessments").  The Phase I  
Assessments did not reveal, nor is the Company aware of, any non-

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

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 
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.

                                  HIGH        LOW          COMMON SHARE 
                                  ----        ---          -------------

Fourth Quarter                   25          20 13/16           0.45 
 
1997
First Quarter                   $26 1/8     $23 3/4            $0.41
Second Quarter                   25 1/2      23 5/8             0.41 
Third Quarter                    27 1/8      24 3/4             0.42 
Fourth Quarter                   28 7/8      25 1/2             0.42
 
As of February 22, 1999, the Common Shares were held by 1,062 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.

<F3>  "Funds from operations" is defined by the National Association of 
Real Estate Investment Trusts ("NAREIT") as net income or loss after 
preferred dividends (computed in accordance with generally accepted 
accounting principles ("GAAP")), excluding gains (or losses) from debt 
restructuring and sales of property, plus real estate-related 
depreciation and amortization and minority interest, and excluding 
significant non-recurring events that materially distort the comparative 
measurement of Company performance over time.  Funds from operations 
does not represent cash generated from operating activities in 
accordance with GAAP and is not necessarily indicative of cash available 
to fund cash needs.

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

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

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

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

- -23-
<PAGE>

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

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

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

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

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

FORWARD-LOOKING STATEMENTS

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

- -25-
<PAGE>
the effect of national and regional economic conditions; the Company's 
ability to identify and secure additional properties and sites that meet 
its criteria for acquisition or development; the availability of 
capital; and the effect of prevailing market interest rates; and other 
risks described from time to time in the Company's filings with the 
Securities and Exchange Commission.  Given these uncertainties, readers 
are cautioned not to place undue reliance on such statements.  The 
Company undertakes no obligation to update statements that may be made 
to reflect any future events or circumstances. 

RESULTS OF OPERATIONS

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

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

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

Total revenue (principally rental revenue and operating expense 
reimbursement) increased to $387.1 million for the year ended December 
31, 1998 from $232.5 million for the year ended December 31, 1997.  This 
increase was primarily due to the increase in the number of Properties 
in Operation owned during the respective periods. As of January 1, 1997, 
the Company owned 259 properties and, through December 31, 1997, 
acquired 170 additional properties and completed development on 20 
properties for a Total Investment (as defined below) of $871.5 million 
and disposed of eight properties for $35.4 million.  As of January 1, 
1998, the Company owned 441 properties, and, through December 31, 1998, 
acquired 144 additional properties and completed the development on 34 
properties for a Total Investment of $863.6 million, and disposed 10 
properties for $18.9 million. Furthermore, total revenue increased 
because the operating expense recovery percentage (the ratio of 
operating expense reimbursement to rental property expenses and real 
estate taxes) increased to 93.4% for the year ended December 31, 1998 
from 90.9% for the year ended December 31, 1997 due to the increase in 
occupancy.  The "Total Investment" for a property is defined as the 
property's purchase price plus closing costs and management's estimate, 
as determined at the time of acquisition, of the cost of necessary 
building improvements in the case of acquisitions, or land costs and 
land and building improvement costs in the case of development projects, 
and where appropriate, other development costs and carrying costs 
required to reach rent commencement.
 
Rental property and real estate tax expenses increased to $108.3 million 
for the year ended December 31, 1998 from $61.1 million for the year 
ended December 31, 1997.  This increase is due to the increase in the 
number of properties owned.

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

General and administrative expenses increased to $15.5 million for the 
year ended December 31, 1998 from $10.7 million for the year ended 
December 31, 1997.  This $4.8 million increase is due to the increase in 
personnel and other related overhead costs necessitated by the increase 
in the number of properties owned during the respective periods. The 
increase is somewhat mitigated by the benefit of certain economies of 
scale experienced by the Company in owning and operating the increased 
number of properties.  Additionally, the year ended December 31, 1998 
reflects the expensing of internal acquisition costs as of January 1, 
1998 in compliance with EITF 97-11, whereas these costs of $1.2 million 
were capitalized in 1997.
 
Depreciation and amortization expenses increased to $67.9 million for 
the year ended December 31, 1998 from $40.8 million for the year ended 
December 31, 1997.  This increase is due to the increase in the number 
of properties owned during the respective periods. 

Interest expense increased to $78.6 million for the year ended December 
31, 1998 from $53.9 million for the year ended December 31, 1997.  This 
increase is due to an increase in the average debt outstanding for the 
respective periods which was $1,233.3 million in 1998 and $787.7 million 
in 1997.  This increase is also due to an increase in the weighted 
average interest rates for the periods, to 7.5% in 1998 from 7.3% in 
1997.
 
As a result of the foregoing, the Company's operating income increased  
to $195.3 million for the year ended December 31, 1998 from $120.0 
million for the year ended December 31, 1997.  In addition, income 
before minority interest increased to $116.7 million for the year ended

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

Total revenue (principally rental revenue and operating expense 
reimbursement) increased to $232.5 million for the year ended December 
31, 1997 from $154.3 million for the year ended December 31, 1996.  This 
increase was primarily due to the increase in the number of properties 
owned during the respective periods. As of January 1, 1996, the Company 
owned 208 properties and, through December 31, 1996, acquired 33 
additional properties and completed development on 19 properties for a 
Total Investment of $232.2 million.  As of January 1, 1997, the Company 
owned 259 properties, and, through December 31, 1997, acquired 170 
additional properties and completed the development on 20 properties for 
a Total Investment of $871.5 million, and disposed of eight properties 
for $35.4 million.  Furthermore, total revenue increased because the 
operating expense recovery percentage (the ratio of operating expense 
reimbursement to rental property expenses and real estate taxes) 
increased to 90.9% for the year ended December 31, 1997 from 87.8% for 
the year ended December 31, 1996 due to the increase in occupancy.
 
Rental property and real estate tax expenses increased to $61.1 million 
for the year ended December 31, 1997 from $40.9 million for the year 
ended December 31, 1996.  This increase is due to the increase in the 
number of properties owned.
 
Property level operating income for the "Same Store" properties  
(properties owned since January 1, 1996) increased to $98.8 million for 
the year ended December 31, 1997 from $94.1 million for the year ended 
December 31, 1996, with straightlining (which recognizes rental revenue 
evenly over the life the lease), and increased to $98.3 million for the 
year ended December 31, 1997 from $93.0 million for the year ended 
December 31, 1996, without straightlining.  These increases of 5.0%, and 
5.7%, respectively are due to increases in rental rates and increases in 
occupancy.

year ended December 31, 1997 from $8.0 million for the year ended 

- -28-
<PAGE>
December 31, 1996.  This $2.7 million increase is due to the increase in 
personnel and other related overhead costs necessitated by the increase 
in the number of properties owned during the respective periods.  This 
increase is somewhat mitigated by the benefit of certain economies of 
scale experienced by the Company in owning and operating the Properties.
 
Depreciation and amortization expenses increased to $40.8 million for 
the year ended December 31, 1997 from $28.2 million for the year ended 
December 31, 1996.  This increase is due to the increase in the number 
of properties owned during the respective periods. 

Interest expense increased to $53.9 million for the year ended December 
31, 1997 from $38.5 million for the year ended December 31, 1996.  This 
increase is due to an increase in the average debt outstanding for the 
respective periods which was $552.4 million in 1996 and $787.7 million 
in 1997.  This increase is partly offset by the lower interest rates on 
the outstanding debt.  The reduction in interest rates was partially the 
result of the Company receiving investment grade ratings from both 
Standard & Poor's Ratings Group ("S&P") and Moody's Investors Service, 
Inc. ("Moody's") during the year which enabled the Company to access 
public debt markets more economically.
 
As a result of the foregoing, the Company's operating income increased  
to $120.0 million for the year ended December 31, 1997 from $77.2 
million for the year ended December 31, 1996.  In addition, income 
before minority interest increased to $66.1 million for the year ended 
December 31, 1997 from $37.6 million for the year ended December 31, 
1996. 

LIQUIDITY AND CAPITAL RESOURCES 
 
As of December 31, 1998, the Company had cash and cash equivalents of  
$14.4 million.
 
Net cash flow provided by operating activities increased to $219.2 
million for the year ended December 31, 1998 from $136.6 million for the 
year ended December 31, 1997.  This $82.6 million increase was primarily 
due to the additional cash flow generated by the greater number of 
properties in service during the latter period as discussed above under 
"Results of Operations".  Net cash flow provided by operations is the 
primary source of liquidity to fund distributions to shareholders and 
for the recurring capital expenditures and re-leasing costs for the 
Company's properties. 

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

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

- -29-
<PAGE>

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

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

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

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

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

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

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

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

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

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

- -31-

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

YEAR 2000 READINESS DISCLOSURE

Background
 
In the past, many computer software programs were written using two 
digits rather than four to define the applicable year.  As a result, 
date-sensitive computer software may recognize a date using "00" as the 
year 1900 rather than the year 2000.  This is generally referred to as 
the Year 2000 issue.  If this situation occurs, the potential exists for 
computer system failures or miscalculations by computer programs, which 
could disrupt operations.
 
Approach
 
The Company has established a group to coordinate the Company's response 
to the Year 2000 issue.  This group, which reports to the President and 
Chief Operating Officer, includes the Company's MIS Director, a Vice-
President-Property Management and its General Counsel, as well as 
support staff.  The Company is in the process of implementing a Year 
2000 compliance program at the Company's offices and properties 
consisting of the following phases: 
 
      PHASE 1  Compilation of an inventory of information technology 
(IT) and non-IT systems that may be sensitive to the Year 2000 problem.
 
      PHASE 2  Identification and prioritization of the critical systems 
from the systems inventory compiled in Phase 1 and inquiries of third 
parties with whom the Company does significant business (i.e., vendors, 
service providers and tenants) as to the state of their Year 2000 
readiness.
 
      PHASE 3   Analysis of critical systems to determine which systems 
are not Year 2000 compliant and evaluation of the costs to repair or 
replace those systems.
 
      PHASE 4   Repair or replace noncompliant systems and testing of 
critical systems.
 
- -32-
<PAGE>

Status

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

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

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

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

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

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

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

- -33-
<PAGE>
ability of such vendor or service provider to provide goods and 
services.  Though this is not considered as significant a risk with 
respect to the suppliers of goods, due to the availability of 
alternative suppliers, the disruption of certain services, such as 
utilities, could, depending upon the extent of the disruption, have a 
material adverse impact on the Company's operations.  To date, the 
Company is not aware of any vendor or service provider Year 2000 issue 
that management believes would have a material adverse impact on the 
Company's operations.  However, the Company has no means of ensuring 
that its vendors or service providers will be Year 2000 ready.  The 
inability of vendors or service providers to complete their Year 2000 
resolution process in a timely fashion could have a adverse impact on 
the Company.  The effect of non-compliance by vendors or service 
providers is not determinable at this time. 

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

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

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

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

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

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

- -34-
<PAGE>

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

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

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

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

Due to the uncertainty of fluctuations in interest rates, the specific 
actions that might be taken by management to mitigate the impact of such 
fluctuations and their possible effects, the sensitivity analysis 
assumes no changes in the Company's financial structure.
 
ITEM 8.   FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA 
- ----------------------------------------------------- 

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

REPORT OF INDEPENDENT AUDITORS 
 
 
 
 
To The Board of Trustees and Shareholders 
Liberty Property Trust 
 
 
 
We have audited the accompanying consolidated balance sheets of Liberty  
Property Trust (the "Trust") as of December 31, 1998 and 1997, and the 
related consolidated statements of operations, shareholders' equity, and 
cash flows for each of the three years in the period ended December 31, 
1998.  Our audits also included the financial statement schedule listed 
in the Index at Item 14(a).  These financial statements and schedule are 
the responsibility of the Trust's management.  Our responsibility is to 
express an opinion on these financial statements and schedule based on 
our audits. 
 
We conducted our audits in accordance with generally accepted auditing  
standards.  Those standards require that we plan and perform the audit  
to obtain reasonable assurance about whether the financial statements  
are free of material misstatement.  An audit includes examining, on a  
test basis, evidence supporting the amounts and disclosures in the  
financial statements.  An audit also includes assessing the accounting  
principles used and significant estimates made by management, as well as  
evaluating the overall financial statement presentation.  We believe  
that our audits provide a reasonable basis for our opinion. 
 
In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the consolidated financial 
position of Liberty Property Trust at December 31, 1998 and 1997, and 
the consolidated results of its operations and its cash flows for each 
of the three years in the period ended December 31, 1998 in conformity 
with generally accepted accounting principles.   Also, in our opinion, 
the related financial statement schedule, when considered in relation to 
the basic financial statements taken as a whole, presents fairly in all 
material respects the information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS OF LIBERTY PROPERTY TRUST 
 
1.   ORGANIZATION 
 
Liberty Property Trust (the "Trust") is a self-administered and self-
managed Maryland real estate investment trust (a "REIT").  Substantially 
all of the Trust's assets are owned directly or indirectly, and 
substantially all of the Trust's operations are conducted directly or 
indirectly, by its subsidiary, Liberty Property Limited Partnership, a 
Pennsylvania limited partnership (the "Operating Partnership" and, 
together with the Trust and its consolidated subsidiaries, the 
"Company"). The Trust is the sole general partner and also a limited 
partner of the Operating Partnership, with a combined equity interest in 
the Operating Partnership of 92.6% at December 31, 1998.  The Company 
provides leasing, property management, acquisition, development, 
construction management, and design management for a portfolio of 
industrial and office properties which are located principally within 
the Southeastern, Mid-Atlantic and Midwestern United States. 
 
2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 
 
Use of Estimates 
 
The preparation of financial statements in conformity with generally  
accepted accounting principles requires management to make estimates and  
assumptions that affect amounts reported in the financial statements and  
accompanying notes.  Actual results could differ from those estimates. 
 
Principles of Consolidation 
 
The Consolidated Financial Statements of the Company include the  
accounts of the Trust, the Operating Partnership and the Operating  
Partnership's consolidated subsidiaries. All significant intercompany 
transactions and accounts have been eliminated.  
 
Certain amounts from prior periods have been restated to conform to  
current year presentation. 
 
Real Estate and Depreciation 
 
The Properties are recorded at the lower of cost or fair value if 
impaired and are depreciated using the straight-line method over their 
estimated useful lives.  The estimated useful lives are as follows: 
 
        Building and improvements          40 years 
        Equipment                          10 years 
        Tenant improvements                Term of the related lease 

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

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

<PAGE>

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:

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

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

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

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

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

Impact of Recently Issued Accounting Standards

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

3.   REAL ESTATE 
 
At December 31, 1998 and 1997, the Company owned and operated industrial

Credit Facility

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

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

Convertible Debentures

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

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

operating expense reimbursement in the accompanying statements of  
operations.  
 
7.  SHAREHOLDERS' EQUITY

Common Shares

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

<PAGE>

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

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

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

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

Preferred Shares

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

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

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

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

Ordinary income                100.0%          95.3%
Capital gains                      -            4.7%

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

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

- -48-
<PAGE>
business on December 31, 1997.  In addition, a Right will be attached to 
each share of Common Stock issued in the future.  Each Right entitles 
the registered holder to purchase from the Company, under certain 
conditions, a unit (a "Rights Plan Unit") consisting of one one-
thousandth of a share of a Series A Junior Participating Preferred 
Share, $0.0001 par value, (the "Junior Preferred Stock"), of the 
Company, for $100 per Rights Plan Unit, subject to adjustment.  The 
Rights become exercisable only if a person or group of affiliated or 
associated persons (an "Acquiring Person") acquires, or obtains the 
right to acquire, beneficial ownership of Common Shares or other voting 
securities ("Voting Stock") that have 10% or more of the voting power of 
the outstanding shares of Voting Stock, or if an Acquiring Person 
commences with or makes an announcement of an intention to make a tender 
offer or exchange offer to acquire beneficial ownership of Voting Stock 
that have 10% or more of the voting power of the outstanding shares of 
Voting Stock.  The Rights are redeemable by the Company at a price of 
$0.0001 per Right.  If not exercised or redeemed, all Rights will expire 
on December 31, 2007.

Dividend Reinvestment Plan

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

8.  SHARE OPTIONS 
 
The Company has elected to follow Accounting Principles Board Opinion  
No. 25, "Accounting for Stock Issued to Employees" (APB 25) and related  
Interpretations in accounting for its employee stock options because, as  
discussed below, the alternative fair value accounting provided for  
under FASB Statement No. 123, "Accounting for Stock-Based Compensation,"  
requires use of option valuation models that were not developed for use  
in valuing employee stock options.  Under APB 25, because the exercise  
price of the Company's employee stock options equals the market price  
of the underlying stock on the date of grant, no compensation expense is  
recognized.  Under FASB Statement No. 123, the Company would recognize 
compensation expense equal to the value of such options upon grant date.
 
The Company's Share Incentive Plan ("Share Incentive Plan") has 
authorized the grant of options to executive officers, other key 
employees, non-employee trustees and consultants of up to 4,033,535  
shares of the Company's Common Shares.  All options granted have 10-year 
terms and vest over a 3-year period, with options to purchase up to 20% 
of the shares exercisable after the first anniversary, up to 50% after 
the second anniversary and 100% after the third anniversary of the date 
of grant. 

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

- -49-
<PAGE>
weighted-average expected life of the option of 8 years, 3 years and 3 
years. 
 
The Black-Scholes option valuation model was developed for use in  
estimating the fair value of traded options which have no vesting  
restrictions and are fully transferable.  In addition, option valuation  
models require the input of highly subjective assumptions including the  
expected stock price volatility.  Because the Company's employee share 
options have characteristics significantly different from those of 
traded options, and because changes in the subjective input assumptions 
can materially affect the fair value estimate, in management's opinion, 
the existing models do not necessarily provide a reliable single measure 
of the fair value of its employee share options. 
 
For purposes of pro forma disclosures, the estimated fair value of the  
options determined according to the Black-Scholes Option pricing model 
is amortized to expense over the options' vesting period.  The  
Company's pro forma information follows (in thousands, except for per  
share amounts): 
                                         1998       1997       1996

Pro forma income available to
   common shareholders                $ 96,673    $  55,538  $ 33,359
 
Pro forma income per common share:

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.

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

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

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

11.   SEGMENT INFORMATION

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

- -51-
<PAGE>
concentrate and hone market knowledge within a geographical area.  
Within these reportable segments, the Company derives its revenues from 
its two product types:  industrial and office properties.

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

REPORT OF INDEPENDENT AUDITORS 
 
 
 
To The Partners  
Liberty Property Limited Partnership  
 
 
 
We have audited the accompanying consolidated balance sheets of Liberty  
Property Limited Partnership ("the Operating Partnership") as of  
December 31, 1998, and 1997, and the related consolidated statements of 
operations, owners' equity, and cash flows for each of the three years 
in the period ended December 31, 1998.  Our audits also included the 
financial statement schedule listed in the Index at Item 14(a).  These 
financial statements and schedule are the responsibility of the 
Operating Partnership's management.  Our responsibility is to express an 
opinion on these financial statements and schedule based on our audits. 
 
We conducted our audits in accordance with generally accepted auditing  
standards.  Those standards require that we plan and perform the audit  
to obtain reasonable assurance about whether the financial statements  
are free of material misstatement.  An audit includes examining, on a  
test basis, evidence supporting the amounts and disclosures in the  
financial statements.  An audit also includes assessing the accounting  
principles used and significant estimates made by management, as well as  
evaluating the overall financial statement presentation.  We believe  
that our audits provide a reasonable basis for our opinion. 
 
In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the consolidated financial 
position of Liberty Property Limited Partnership at December 31, 1998 
and 1997, and the consolidated results of its operations and its cash 
flows for each of the three years in the period ended December 31, 1998, 
in conformity with generally accepted accounting principles.   Also, in 
our opinion, the related financial statement schedule, when considered 
in relation to the basic financial statements taken as a whole, presents 
fairly in all material respects the information set forth therein.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS OF 
                LIBERTY PROPERTY LIMITED PARTNERSHIP
  
1.   ORGANIZATION 
 
Liberty Property Trust (the "Trust") is a self-administered and self-
managed Maryland real estate investment trust (a "REIT").  Substantially 
all of the Trust's assets are owned directly or indirectly, and 
substantially all of the Trust's operations are conducted directly or 
indirectly, by its subsidiary, Liberty Property Limited Partnership, a 
Pennsylvania limited partnership (the "Operating Partnership" and, 
together with the Trust and its consolidated subsidiaries, the 
"Company"). The Trust is the sole general partner and also a limited 
partner of the Operating Partnership, with a combined equity interest in 
the Operating Partnership of 92.6% at December 31, 1998.  The Company 
provides leasing, property management, acquisition, development, 
construction management, and design management for a portfolio of 
industrial and office properties which are located principally within 
the Southeastern, Mid-Atlantic and Midwestern United States. 
 
2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 
 
Use of Estimates 
 
The preparation of financial statements in conformity with generally  
accepted accounting principles requires management to make estimates and  
assumptions that affect amounts reported in the financial statements and  
accompanying notes.  Actual results could differ from those estimates. 
 
Principles of Consolidation 
 
The Consolidated Financial Statements of the Company include the 
accounts of the Operating Partnership and the Operating Partnership's  
consolidated subsidiaries. All significant intercompany transactions and 
accounts have been eliminated. 
 
Certain amounts from prior periods have been restated to conform to  
current year presentation. 
 
Real Estate and Depreciation 
 
The Properties are recorded at the lower of cost or fair value if 
impaired and are depreciated using the straight-line method over their 
estimated useful lives.  The estimated lives are as follows: 
 
        Building and improvements              40 years 
        Equipment                              10 years 
        Tenant improvements                    Term of the related lease 

Expenditures directly related to acquisition, development or improvement 
of real estate are capitalized as a cost of the property.  Expenditures 
for maintenance and repairs are charged to operations as incurred.
 
The Company evaluates its real estate investments upon occurrence of 
significant adverse changes in their operations to assess whether any 
impairment indications are present that affect the recovery of the 
recorded value.  If any real estate investment is considered impaired, a 
loss is provided to reduce the carrying value of the property to its 
estimated fair value.

- -87-
<PAGE>

Cash and Cash Equivalents 
 
Highly liquid investments with a maturity of three months or less when  
purchased are classified as cash equivalents.  The carrying amount of  
these assets approximates their fair market value.  
 
Revenues 
 
The Company earns rental income under operating leases with tenants.   
Rental income is recognized on a straight-line basis over the applicable  
lease term. 
 
Deferred Financing and Leasing Costs 
 
Costs incurred in connection with financing or leasing are capitalized  
and amortized over the term of the related loan or lease. Amortization  
of deferred financing costs is reported as interest expense. 
 
Income Taxes 
 
In conformity with the Internal Revenue Code and applicable state and  
local tax statutes, taxable income or loss of the Operating Partnership  
is required to be reported in the tax returns of the partners in  
accordance with the terms of the Partnership Agreement and, accordingly,  
no provision has been made in the accompanying financial statements for  
any federal, state, or local income taxes. 

Impact of Recently Issued Accounting Standards

In June 1998, the FASB issued Statement No. 133, "Accounting for 
Derivative Instruments and Hedging Activities".  The Company expects to 
adopt the new Statement effective January 1, 2000.  The Statement will 
require the Company to recognize all derivatives on the balance sheet at 
fair value.  The Company does not anticipate that the adoption of this 
statement will have a significant effect on its results of operations or 
financial position.
 
3.   REAL ESTATE 
 
At December 31, 1998 and 1997, the Company owned and operated industrial 
and office properties located principally in suburban mixed use

Credit Facility

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

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

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

- -90-
<PAGE>
convertible debentures is 9.0%.  At December 31, 1997, the effective 
interest rate on the convertible debentures was 8.4%.  During the year 
ended December 31, 1997, the Company paid sums aggregating $98,000 to 
facilitate the conversion of $17.3 million of convertible debentures 
into 862,650 Common Shares. There was no such expense in 1998. At 
December 31, 1998 and 1997 the convertible debentures were convertible 
into 5,080,950 and 5,577,150 Common Shares, respectively.  

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

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

7.   PREFERRED UNITS

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

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

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

- -91-
<PAGE>
approximately 775 acres of land for commercial development.  The 
purchase price of the land as of December 31, 1998 is $16.2 million.

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

10.   SEGMENT INFORMATION

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

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

Liberty Property Limited Partnership, a Pennsylvania limited partnership 
(the "Company," which term includes any successor entity under the 
Indenture hereinafter referred to), for value received, hereby promises 
to pay to    CEDE & CO. , or registered assigns, upon presentation, the 
principal sum of $   20,000,000  (Twenty Million)     , on the Stated 
Maturity Date specified above (or any Redemption Date or Repayment Date, 
each as defined on the reverse hereof) (each such Stated Maturity Date, 
Redemption Date or Repayment Date being hereinafter referred to as the 
"Maturity Date" with respect to the principal repayable on such date) 
and to pay interest thereon, at the Interest Rate per annum specified 
above, until the principal hereof is paid or duly made available for 
payment, and (to the extent that the payment of such interest shall be 
legally enforceable) at the Default Rate per annum specified above on 
any overdue principal, premium and/or interest.  The Company will pay 
interest in arrears on each Interest Payment Date, if any, specified 
above (each, an "Interest Payment Date"), commencing with the first 
Interest Payment Date next succeeding the Original Issue Date specified 
above, and on the Maturity Date; provided, however, that if the Original 
Issue Date occurs between a Record Date (as defined below) and the next 
succeeding Interest Payment Date, interest payments will commence on the 
second Interest Payment Date next succeeding the Original Issue Date to 
the holder of this Note on the Record Date with respect to such second 
Interest Payment Date.  Interest on this Note will be computed on the 
basis of a 360-day year of twelve 30-day months.

Interest on this Note will accrue from, and including, the immediately 
preceding Interest Payment Date to which interest has been paid or duly 
provided for (or from, and including, the Original Issue Date if no 
interest has been paid or duly provided for) to, but excluding, the 
applicable Interest Payment Date or the Maturity Date, as the case may 
be (each, an "Interest Period").  The interest so payable, and 
punctually paid or duly provided for, on any Interest Payment Date will, 
subject to certain exceptions described herein, be paid to the person in 
whose name this Note (or one or more predecessor Notes) is registered at 
the close of business on the fifteenth calendar day (whether or not a 
Business Day, as defined below) immediately preceding such Interest 
Payment Date (the "Record Date"); provided, however, that interest 
payable on the Maturity Date will be payable to the person to whom the 
principal hereof and premium, if any, hereon shall be payable.  Any such 
interest not so punctually paid or duly provided for ("Defaulted 
Interest") will forthwith cease to be payable to the holder on any 
Record Date, and shall be paid to the person in whose name this Note is 
registered at the close of business on a special record date (the 
"Special Record Date") for the payment of such Defaulted Interest to be 
fixed by the Trustee hereinafter referred to, notice whereof shall be 
given to the holder of this Note by the Trustee not less than 10 days 
prior to such Special Record Date or may be paid at any time in any 
other lawful manner not inconsistent with the requirements of any 
securities exchange on which this Note may be listed, and upon such 
notice as may be required by such exchange, all as more fully provided 
for in the Indenture.

Payment of principal, premium, if any, and interest in respect of this 
Note due on the Maturity Date will be made in immediately available 
funds upon presentation and surrender of this Note (and, with respect to 
any applicable repayment of this Note, upon presentation and surrender 
of this Note and a duly completed election form as contemplated on the 
reverse hereof) at the office or agency maintained by the Company for 
that purpose in the Borough of Manhattan, The City of New York, 
currently the office of the Trustee located at First National Bank of 
Chicago, c/o First Chicago Trust Company of New York, 14 Wall Street, 
8th Floor, New York, New York 10005, or at such other paying agency in 
the Borough of Manhattan, The City of New York, as the Company may 
determine; provided, however, that if the Specified Currency specified 
above is other than United States dollars and such payment is to be made 
in the Specified Currency in accordance with the provisions set forth 
below, such payment will be made by wire transfer of immediately 
available funds to an account with a bank designated by the holder 
hereof at least 15 calendar days prior to the Maturity Date, provided 
that such bank has appropriate facilities therefor and that this Note 
(and, if applicable, a duly completed repayment election form) is 
presented and surrendered at the aforementioned office or agency 
maintained by the Company in time for the Trustee to make such payment 
in such funds in accordance with its normal procedures.  Payment of 
interest due on any Interest Payment Date other than the Maturity Date 
will be made at the aforementioned office or agency maintained by the 
Company or, at the option of the Company, by check mailed to the address 
of the person entitled thereto as such address shall appear in the 
Security Register maintained by the Trustee; provided, however, that a 
holder of U.S. $10,000,000 (or, if the Specified Currency is other than 
United States dollars, the equivalent thereof in the Specified Currency) 
or more in aggregate principal amount of Notes (whether having identical 
or different terms and provisions) will be entitled to receive interest 
payments on any Interest Payment Date other than the Maturity Date by 
wire transfer of immediately available funds if appropriate wire 
transfer instructions have been received in writing by the Trustee not 
less than 15 calendar days prior to such Interest Payment Date.  Any 
such wire transfer instructions received by the Trustee shall remain in 
effect until revoked by such holder.

If any Interest Payment Date or the Maturity Date falls on a day that is 
not a Business Day, the required payment of principal, premium, if any, 
and/or interest shall be made on the next succeeding Business Day with 
the same force and effect as if made on the date such payment was due, 
and no interest shall accrue with respect to such payment for the period 
from and after such Interest Payment Date or the Maturity Date, as the 
case may be, to the date of such payment on the next succeeding Business 
Day.

As used herein, "Business Day" means any day, other than a Saturday or 
Sunday, that is neither a legal holiday nor a day on which banking 
institutions are authorized or required by law, regulation or executive 
order to close in The City of New York or Chicago, Illinois; provided, 
however, that if the Specified Currency is other than United States 
dollars, such day is also not a day on which banking institutions are 
authorized or required by law, regulation or executive order to close in 
the Principal Financial Center (as defined below) of the country issuing 
the Specified Currency (unless the Specified Currency is European 
Currency Units ("ECU"), in which case such day is also not a day that 
appears as an ECU non-settlement day on the display designated as "ISDE" 
on the Reuter Monitor Money Rates Service (or a day so designated by the 
ECU Banking Association) or, if ECU non-settlement days do not appear on 
that page (and are not so designated), a day that is not a day on which 
payments in ECU cannot be settled in the international interbank 
market); provided that, with respect to Notes as to which LIBOR is an 
applicable Interest Rate Basis, such day is also a London Business Day 
(as defined below).  "London Business Day" means any day on which 
dealings in the Designated LIBOR Currency (as defined below) are 
transacted in the London interbank market.  "Principal Financial Center" 
means (i) the capital city of the country issuing the Specified Currency 
(except as described in the immediately preceding sentence with respect 
to ECU) or (ii) the capital city of the country which the Designated 
LIBOR Currency, if applicable, relates (or, in the case of ECU, 
Luxembourg), except, in each case, that with respect to United States 
dollars, Australian dollars, Canadian dollars, Deutsche marks, Dutch 
guilders, Italian lire, Swiss francs and ECUs, the "Principal Financial 
Center" shall be The City of New York, Sydney, Toronto, Frankfurt, 
Amsterdam, Milan (solely in the case of clause (i) above), Zurich and 
Luxembourg, respectively.

The Company is obligated to make payments of principal, premium, if any, 
and interest in respect of this Note in the Specified Currency (or, if 
the Specified Currency is not at the time of such payment legal tender 
for the payment of public and private debts, in such other coin or 
currency of the country which issued the Specified Currency as at the 
time of such payment is legal tender for the payment of such debts).  If 
the Specified Currency is other than United States dollars, except as 
provided below, any such amounts so payable by the Company will be 
converted by the Exchange Rate Agent specified above into United States 
dollars for payment to the holder of this Note.

If the Specified Currency is other than United States dollars, the 
holder of this Note may elect to receive such amounts in such Specified 
Currency.  If the holder of this Note shall not have duly made an 
election to receive all or a specified portion of any payment of 
principal, premium, if any, and/or interest in respect of this Note in 
the Specified Currency, any United States dollar amount to be received 
by the holder of this Note will be based on the highest bid quotation in 
The City of New York received by the Exchange Rate Agent at 
approximately 11:00 A.M., New York City time, on the second Business Day 
preceding the applicable payment date from three recognized foreign 
exchange dealers (one of whom may be the Exchange Rate Agent) selected 
by the Exchange Rate Agent and approved by the Company for the purchase 
by the quoting dealer of the Specified Currency for United States 
dollars for settlement on such payment date in the aggregate amount of 
the Specified Currency payable to all holders of Notes payable in the 
Specified Currency who are scheduled to receive United States dollar 
payments and at which the applicable dealer commits to execute a 
contract.  All currency exchange costs will be borne by the holder of 
this Note by deductions from such payments.  If three such bid 
quotations are not available, payments on this Note will be made in the 
Specified Currency unless the Specified Currency is not available due to 
the imposition of exchange controls or other circumstances beyond the 
control of the Company.

If the Specified Currency is other than United States dollars, the 
holder of this Note may elect to receive all or a specified portion of 
any payment of principal, premium, if any, and/or interest in respect of 
this Note in the Specified Currency by submitting a written request for 
such payment to the Trustee at its corporate trust office in The City of 
New York on or prior to the applicable Record Date or at least 15 
calendar days prior to the Maturity Date, as the case may be.  Such 
written request may be mailed or hand delivered or sent by cable, telex 
or other form of facsimile transmission.  The holder of this Note may 
elect to receive all or a specified portion of all future payments in 
the Specified Currency in respect of such principal, premium, if any, 
and/or interest and need not file a separate election for each payment.  
Such election will remain in effect until revoked by written notice to 
the Trustee, but written notice of any such revocation must be received 
by the Trustee on or prior to the applicable Record Date or at least 15 
calendar days prior to the Maturity Date, as the case may be.

If the Specified Currency is other than United States dollars or a 
composite currency and the holder of this Note shall have duly made an 
election to receive all or a specified portion of any payment of 
principal, premium, if any, and/or interest in respect of this Note in 
the Specified Currency and if the Specified Currency is not available 
due to the imposition of exchange controls or other circumstances beyond 
the control of the Company, the Company will be entitled to satisfy its 
obligations to the holder of this Note by making such payment in United 
States dollars on the basis of the Market Exchange Rate (as defined 
below), computed by the Exchange Rate Agent, on the second Business Day 
prior to such payment date or, if such Market Exchange Rate is not then 
available, on the basis of the most recently available Market Exchange 
Rate, or as otherwise specified on the face hereof.  The "Market 
Exchange Rate" for the Specified Currency means the noon dollar buying 
rate in The City of New York for cable transfers for the Specified 
Currency as certified for customs purposes by (or, if not so certified, 
as otherwise determined by) the Federal Reserve Bank of New York.  Any 
payment made under such circumstances in United States dollars will not 
constitute an Event of Default (as defined in the Indenture) with 
respect to this Note.

If the Specified Currency is a composite currency and the holder of this 
Note shall have duly made an election to receive all or a specified 
portion of any payment of principal, premium, if any, and/or interest in 
respect of this Note in the Specified Currency and if such composite 
currency is unavailable due to the imposition of exchange controls or 
other circumstances beyond the control of the Company, then the Company 
will be entitled to satisfy its obligations to the holder of this Note 
by making such payment in United States dollars on the basis of the 
equivalent of the composite currency in United States dollars.  The 
component currencies of the composite currency for this purpose 
(collectively, the "Component Currencies" and each, a "Component 
Currency") shall be the currency amounts that were components of the 
composite currency as of the last day on which the composite currency 
was used.  The equivalent of the composite currency in United States 
dollars shall be calculated by aggregating the United States dollar 
equivalents of the Component Currencies.  The United States dollar 
equivalent of each of the Component Currencies shall be determined by 
the Exchange Rate Agent on the basis of the Market Exchange Rate on the 
second Business Day prior to the required payment, or, if such Market 
Exchange Rate is not then available, on the basis of the most recently 
available Market Exchange Rate for each such Component Currency, or as 
otherwise specified on the face hereof.

If the official unit of any Component Currency is altered by way of 
combination or subdivision, the number of units of the currency as a 
Component Currency shall be divided or multiplied in the same 
proportion.  If two or more Component Currencies are consolidated into a 
single currency, the amounts of those currencies as Component Currencies 
shall be replaced by an amount in such single currency equal to the sum 
of the amounts of the consolidated Component Currencies expressed in 
such single currency.  If any Component Currency is divided into two or 
more currencies, the amount of the original Component Currency shall be 
replaced by the amounts of such two or more currencies, the sum of which 
shall be equal to the amount of the original Component Currency.

All determinations referred to above made by the Exchange Rate Agent 
shall be at its sole discretion and shall, in the absence of manifest 
error, be conclusive for all purposes and binding on the holder of this 
Note.

Reference is hereby made to the further provisions of this Note set 
forth on the reverse hereof and, if so specified above on the face 
hereof, in the Addendum hereto, which further provisions shall have the 
same force and effect as if set forth on the face hereof.

Notwithstanding any provisions to the contrary contained herein, if the 
face of this Note specifies that an Addendum is attached hereto or that 
"Other/Additional Provisions" apply to this Note, this Note shall be 
subject to the terms set forth in such Addendum or such 
"Other/Additional Provisions."

Unless the Certificate of Authentication hereon has been executed by or 
on behalf of the Trustee by manual signature, this Note shall not be 
entitled to any benefit under the Indenture or be valid or obligatory 
for any purpose.

IN WITNESS WHEREOF, Liberty Property Limited Partnership has caused this 
Note to be duly executed by one of its duly authorized officers.

TRUSTEE'S CERTIFICATE OF AUTHENTICATION

   This is one of the Securities of the series designated therein

THE FIRST NATIONAL BANK OF CHICAGO,
     as Trustee




By:  /s/ Mark J. Frye

Date:  October 24, 1997
       Authorized Signatory




                             (REVERSE OF NOTE)

                   LIBERTY PROPERTY LIMITED PARTNERSHIP
                              MEDIUM-TERM NOTE
                                (Fixed Rate)


This Note is one of a duly authorized series of Securities (the 
"Securities") of the Company issued and to be issued under an Indenture, 
dated as of October 24, 1997, as amended, modified or supplemented from 
time to time (the "Indenture"), between the Company and The First 
National Bank of Chicago, as Trustee (the "Trustee," which term includes 
any successor trustee under the Indenture), to which Indenture and all 
indentures supplemental thereto reference is hereby made for a statement 
of the respective rights, limitations of rights, duties and immunities 
thereunder of the Company, the Trustee and the holders of the 
Securities, and of the terms upon which the Securities are, and are to 
be, authenticated and delivered.  This Note is one of the series of 
Securities designated as "Medium-Term Notes Due Nine Months or More from 
Date of Issue" (the "Notes").  All terms used but not defined in this 
Note or in an Addendum hereto shall have the meanings assigned to such 
terms in the Indenture or on the face hereof, as the case may be.

This Note is issuable only in registered form without coupons in minimum 
denominations of U.S. $1,000 and integral multiples thereof or the 
minimum Authorized Denomination specified on the face hereof.

This Note will not be subject to any sinking fund and, unless otherwise 
specified on the face hereof in accordance with the provisions of the 
following two paragraphs, will not be redeemable or repayable prior to 
the Stated Maturity Date.

This Note will be subject to redemption at the option of the Company on 
any date on or after the Initial Redemption Date, if any, specified on 
the face hereof, in whole or from time to time in part in increments of 
U.S. $1,000 or the minimum Authorized Denomination (provided that any 
remaining principal amount hereof shall be at least U.S. $1,000 or such 
minimum Authorized Denomination), at the Redemption Price (as defined 
below), together with unpaid interest accrued thereon to the date fixed 
for redemption (each, a "Redemption Date"), on written notice given to 
the holder hereof not more than 60 nor less than 30 calendar days prior 
to the Redemption Date and in accordance with the provisions of the 
Indenture.  The "Redemption Price," if any, shall initially be the 
Initial Redemption Percentage specified on the face hereof multiplied by 
the unpaid principal amount of this Note to be redeemed.  The Initial 
Redemption Percentage, if any, shall decline at each anniversary of the 
Initial Redemption Date by the Annual Redemption Percentage Reduction, 
if any, specified on the face hereof until the Redemption Price is 100% 
of the unpaid principal amount to be redeemed.  In the event of 
redemption of this Note in part only, a new Note of like tenor for the 
unredeemed portion hereof and otherwise having the same terms as this 
Note shall be issued in the name of the holder hereof upon the 
presentation and surrender hereof.

This Note will be subject to repayment by the Company at the option of 
the holder hereof on the Optional Repayment Date(s), if any, specified 
on the face hereof, in whole or in part in increments of U.S. $1,000 or 
the minimum Authorized Denomination (provided that any remaining 
principal amount hereof shall be at least U.S. $1,000 or such minimum 
Authorized Denomination), at a repayment price equal to 100% of the 
unpaid principal amount to be repaid, together with unpaid interest 
accrued thereon to the date fixed for repayment (each, a "Repayment 
Date").  If an Optional Repayment Date is not set forth on the face 
hereof, this Note will not be repayable at the option of the holder 
hereof prior to Maturity.  For this Note to be repaid, the Trustee must 
receive at its office in the Borough of Manhattan, The City of New York, 
referred to on the face hereof, at least 30 days but not more than 60 
days prior to the Repayment Date this Note and the form hereon entitled 
"Option to Elect Repayment" duly completed.  Exercise of such repayment 
option by the holder hereof will be irrevocable.  In the event of 
repayment of this Note in part only, a new Note of like tenor for the 
unrepaid portion hereof and otherwise having the same terms as this Note 
shall be issued in the name of the holder hereof upon the presentation 
and surrender hereof.

If this Note is a Discount Note as specified on the face hereof, the 
amount payable to the holder of this Note in the event of redemption, 
repayment or acceleration of maturity of this Note will be equal to the 
sum of (i) the Issue Price specified on the face hereof (increased by 
any accruals of the Discount, as defined below) and, in the event of any 
redemption of this Note (if applicable), multiplied by the Initial 
Redemption Percentage (as adjusted by the Annual Redemption Percentage 
Reduction, if applicable) and (ii) any unpaid interest on this Note 
accrued from the Original Issue Date to the Redemption Date, Repayment 
Date or date of acceleration of maturity, as the case may be.  The 
difference between the Issue Price and 100% of the principal amount of 
this Note is referred to herein as the "Discount."

For purposes of determining the amount of Discount that has accrued as 
of any Redemption Date, Repayment Date or date of acceleration of 
maturity of this Note, such Discount will be accrued so as to cause the 
yield on the Note to be constant. The constant yield will be calculated 
using a 30-day month, 360-day year convention, a compounding period 
that, except for the Initial Period (as defined below), corresponds to 
the shortest period between Interest Payment Dates (with ratable 
accruals within a compounding period), and an assumption that the 
maturity of this Note will not be accelerated.  If the period from the 
Original Issue Date to the initial Interest Payment Date (the "Initial 
Period") is shorter than the compounding period for this Note, a 
proportionate amount of the yield for an entire compounding period will 
be accrued.  If the Initial Period is longer than the compounding 
period, then such period will be divided into a regular compounding 
period and a short period, with the short period being treated as 
provided in the preceding sentence.

If an Event of Default, as defined in the Indenture, shall occur and be 
continuing, the principal of and premium (if any) and interest on the 
Notes either shall automatically become or may be declared due and 
payable in the manner and with the effect provided in the Indenture.

The Indenture contains provisions for defeasance at any time of (a) the 
entire indebtedness of the Company on this Note and (b) certain 
restrictive covenants and the related defaults and Events of Default 
applicable to the Company, in each case, upon compliance by the Company 
with certain conditions set forth in the Indenture, which provisions 
apply to this Note.

As provided in and subject to the provisions of the Indenture, the 
holder of this Note shall not have the right to institute any proceeding 
with respect to the Indenture or for the appointment of a receiver or 
trustee or for any other remedy hereunder, unless (i) such holder shall 
have previously given written notice to the Trustee of a continuing 
Event of Default with respect to the Securities of this series, (ii) the 
holders of not less than 25% in principal amount of the Securities of 
this series at the time Outstanding shall have made written request to 
the Trustee to institute proceedings in respect of such Event of Default 
in its own name as Trustee, (iii) such holder or holders have offered 
reasonable indemnity satisfactory to the Trustee against the costs, 
expenses and liabilities to be incurred in compliance with such request, 
(iv) the Trustee shall have failed to institute any such proceeding for 
60 days after its receipt of such notice, request and offer of 
indemnity, and (v) the Trustee shall not have received, during the 60-
day period referenced in clause (iv) above, from the holders of a 
majority in principal amount of Securities of this series at the time 
Outstanding in a direction inconsistent with such request; provided 
that, no one or more holder shall have any right in any manner whatever 
by virtue of, or by availing of, any provision of the Indenture to 
affect, disturb or prejudice the rights of any other holder, or to 
obtain or to seek to obtain priority or preference over any other holder 
or to enforce any right under the Indenture, except in the manner 
therein provided and for the equal and ratable benefit of all holders.  
The foregoing shall not apply to any suit instituted by the holder of 
this Note for the enforcement of any payment of principal hereof (and 
premium or Make-Whole Amount, if any) or any interest thereon on or 
after the respective due dates expressed herein.

The Indenture permits, with certain exceptions as therein provided, the 
amendment thereof and the modification of the rights and obligations of 
the Company and the rights of the holders of the Securities at any time 
by the Company and the Trustee with the consent of the holders of not 
less than a majority of the aggregate principal amount of all Securities 
at the time outstanding and affected thereby.  The Indenture also 
contains provisions permitting the holders of not less than a majority 
of the aggregate principal amount of the outstanding Securities of any 
series, on behalf of the holders of all such Securities, to waive 
compliance by the Company with certain provisions of the Indenture.  
Furthermore, provisions in the Indenture permit the holders of not less 
than a majority of the aggregate principal amount of the outstanding 
Securities of any series, in certain instances, to waive, on behalf of 
all of the holders of Securities of such series, certain past defaults 
under the Indenture and their consequences.  Any such consent or waiver 
by the holder of this Note shall be conclusive and binding upon such 
holder and upon all future holders of this Note and other Notes issued 
upon the registration of transfer hereof or in exchange heretofore or in 
lieu hereof, whether or not notation of such consent or waiver is made 
upon this Note.

No reference herein to the Indenture and no provision of this Note or of 
the Indenture shall alter or impair the obligation of the Company, which 
is absolute and unconditional, to pay principal, premium, if any, and 
interest in respect of this Note at the times, places and rate or 
formula, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein 
and herein set forth, the transfer of this Note is registrable in the 
Security Register of the Company upon surrender of this Note for 
registration of transfer at the office or agency of the Company in any 
place where the principal hereof and any premium or interest hereon are 
payable, duly endorsed by, or accompanied by a written instrument of 
transfer in form satisfactory to the Company and the Security Registrar 
duly executed by, the holder hereof or by his attorney duly authorized 
in writing, and thereupon one or more new Notes, of authorized 
denominations and for the same aggregate principal amount, will be 
issued to the designated transferee or transferees.

As provided in the Indenture and subject to certain limitations therein 
and herein set forth, this Note is exchangeable for a like aggregate 
principal amount of Notes of different authorized denominations but 
otherwise having the same terms and conditions, as requested by the 
holder hereof surrendering the same.

No service charge shall be made for any such registration of transfer or 
exchange, but the Company may require payment of a sum sufficient to 
cover any tax or other governmental charge payable in connection 
therewith.

Prior to due presentment of this Note for registration of transfer, the 
Company, the Trustee and any agent of the Company or the Trustee may 
treat the holder in whose name this Note is registered as the owner 
thereof for all purposes, whether or not this Note be overdue, and 
neither the Company, the Trustee nor any such agent shall be affected by 
notice to the contrary.

No recourse under or upon any obligation, covenant or agreement 
contained in the Indenture or in this Note, or because of any 
indebtedness evidenced thereby or hereby, (including without limitation, 
any obligation or indebtedness relating to the principal of, or premium 
or Make-Whole Amount, if any, interest or any other amounts due, or 
claimed to be due, on this Security), or for any claim based thereon or 
otherwise in respect thereof, shall be had (i) against Liberty Property 
Trust or any other partner of the Company, (ii) against any person which 
owns an interest, directly or indirectly, in any partner in the Company, 
or (iii) against any promoter, as such or, against any past, present or 
future stockholder, partner, officer or director, as such, of the 
Company or of any successor, either directly or through the Company or 
any successor, under any rule of law, statue or constitutional provision 
or by the enforcement of any assessment or by any legal or equitable 
proceeding or otherwise, all such liability being expressly waived and 
released by the acceptance of this Note by the holder thereof and as 
part of the consideration for the issue of the Securities of this 
series.  The holder of this Security acknowledges by acceptance of this 
Security that its sole remedies under the Indenture for any Default by 
the Company in the payment of principal of, or any premium or Make-Whole 
Amount, if any, interest or any amounts due, or claimed to be due, on 
this Security, or otherwise, are limited to claims against the property 
of the Company as provided in Sections 111 and 503 of the Indenture.

THE INDENTURE AND THE SECURITIES, INCLUDING THIS NOTE, SHALL BE GOVERNED 
BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

Pursuant to a recommendation promulgated by the Committee on Uniform 
Security Identification Procedures, the Company has caused "CUSIP" 
numbers to be printed on the Securities of this series as a convenience 
to the holders of such Securities.  No representation is made as to the 
correctness or accuracy of such CUSIP numbers as printed on the 
Securities, and reliance may be placed only on the other identification 
numbers printed hereon.

periods of time as Borrower has included the same on the list of 
Unencumbered Properties attached to the most recent Compliance 
Certificate delivered hereunder.

Property at any time, an amount computed as follows: (a) the Net 
Operating Income of such Unencumbered Property for the most recent 
fiscal quarter of the Borrower for which financial statements have been 
delivered to the Agent pursuant to 7.4; (b) then multiplying by four 
(4);  (c) then subtracting from such annualized Net Operating Income the

exceeds fifteen percent (15%) of the Value of All Unencumbered 
Properties as of the end of the most recent fiscal quarter of the 
Borrower for which financial statements have been delivered to the Agent 
pursuant to 7.4 then the amount in excess of said 15% level will be 
excluded when computing the Unencumbered Property Value for such 
Unencumbered Property.  With respect to any Unencumbered Property which, 
during the applicable fiscal quarter, has been acquired by Borrower or 
has had the building or buildings being constructed thereon completed 
and occupied by tenants, Borrower may compute the Unencumbered Property 
Value for such Unencumbered Property based on a pro forma Net Operating 
Income for such fiscal quarter, which computation must be approved by 
the Agent.

the Related Companies which is not secured by a Lien on any Properties 
including, without limitation, the Loans, the loans under the Revolving 
Credit Facility, the Subordinated Indebtedness and any Indebtedness 
evidenced by any bonds, debentures, notes or other debt securities 
presently outstanding or which may be hereafter issued by Borrower or by 
the Company.  Unsecured Indebtedness shall not include accrued ordinary 
operating expenses payable on a current basis.

     Value of All Unencumbered Properties. When determined as of the end 
of a fiscal quarter, an amount computed as follows: (a) Unencumbered Net 
Operating Income;  (b) then multiplying by four (4);  (c) then 
subtracting from such annualized Net Operating Income the Reserve Amount 
for all Unencumbered Properties;  and (d) dividing such difference by 
0.095.  When determined as of a date which is during a fiscal quarter 
based on an updated list of Unencumbered Properties attached to the 
applicable Compliance Certificate, the Value of All Unencumbered 
Properties most recently computed as provided in the preceding sentence 
of this definition will be adjusted by subtracting the Unencumbered 
Property Value of the previous Unencumbered Properties which have been 
deleted from such list and by adding the Unencumbered Property Value of 
the Unencumbered Properties which have been added to such list; 
provided, however, that to the extent the addition of Unencumbered 
Properties located in the United Kingdom causes the aggregate 
Unencumbered Property Values of the Unencumbered Properties located in 
the United Kingdom to exceed four percent (4%) of the Value of All 
Encumbered Properties, the amount in excess of said 4% level will be 
excluded when computing the Value of All Unencumbered Properties. 

     Variable Rate Indebtedness.  The Loans and all other Indebtedness

through maturity or for a term of at least thirty-six  (36) months from

entity involved, or (b) to control, manage or conduct the business of 
the corporation, partnership, association, trust or other business 
entity involved.

2.     TERM LOAN FACILITY.

     2.1.     Commitment to Lend.  Subject to the provisions of 10 and 
the other terms and conditions set forth in this Agreement, each of the 
Banks severally agrees to lend to the Borrower on the Closing Date the 
principal amount equal to such Bank's Commitment. Any amounts repaid 
pursuant to  3 may not be reborrowed.               

     2.2.     The Notes. The Loans shall be evidenced by separate 
promissory notes of the Borrower in substantially the form of Exhibit A 
hereto (each a "Note"), and completed with appropriate insertions.  One 
or more Notes shall be payable to the order of each Bank in an aggregate 
principal amount equal to such Bank's Commitment. The Borrower 
irrevocably authorizes each Bank to make or cause to be made, at or 
about the time of the Funding Date of any Loan or at the time of receipt 
of any payment of principal on such Bank's Note, an appropriate notation 
on such Bank's Record reflecting the making of such Loan or (as the case 
may be) the receipt of such payment. The Outstanding amount of the Loans 
set forth on such Bank's Record shall (absent manifest error) be prima 
facie evidence of the principal amount thereof owing and unpaid to such 
Bank, but the failure to record, or any error in so recording, any such 
amount on the Record shall not limit or otherwise affect the obligations 
of the Borrower hereunder or under any Note to make payments of 
principal of or interest on any Note when due.

     2.3.      Interest on Loans.

          (a)  Each Base Rate Loan shall bear interest for the period 
commencing with the Funding Date thereof and ending on the last day of 
the Interest Period with respect thereto at the Base Rate.

          (b)  Each Eurodollar Rate Loan shall bear interest for the 
period commencing with the Funding Date thereof and ending on the last 
day of the Interest Period with respect thereto at the rate equal to the 
Applicable Margin per annum above the Eurodollar Rate determined for 
such Interest Period.

          (c)  The Borrower unconditionally promises to pay interest on 
each Loan in arrears on each Interest Payment Date with respect thereto.

     2.4.      Interest Options .  The Loans advanced on the Closing 
Date shall be Eurodollar Rate Loans with an Interest Period of 6 months.  
After the expiration of such initial Interest Period, Outstanding Loans 
may be converted or continued as follows:

          (a) The Borrower may elect from time to time to convert any 
Outstanding Loan to a Loan of another Type, provided that (i) with 
respect to any such conversion of a Eurodollar Rate Loan to a Base Rate 
Loan, the Borrower shall give the Agent at least three (3) Business 
Days, prior written notice of such election; (ii) with respect to any 
such conversion of a Eurodollar Rate Loan into a Base Rate Loan, such 
conversion shall only be made on the last day of the Interest Period 
with respect thereto; (iii) subject to the further proviso at the end of 
this section and subject to 2.4(b) and 2.4(d) hereof with respect to any 
such conversion of a Base Rate Loan to a Eurodollar Rate Loan, the 
Borrower shall give the Agent at least four (4) Eurodollar Business 
Days, prior written notice of such election and (iv) no Loan may be 
converted into a Eurodollar Rate Loan when any Default or Event of 
Default has occurred and is continuing. On the date on which such 
conversion is being made, each Bank shall take such action as is 
necessary to transfer its Facility Percentage of such Loans to its 
Domestic Lending Office or its Eurodollar Lending Office, as the case 
may be. All or any part of Outstanding Loans of any Type may be 
converted as provided herein, provided further that each Conversion 
Request relating to the conversion of a Base Rate Loan to a Eurodollar 
Rate Loan shall be for an amount equal to $5,000,000 or an integral 
multiple of $1,000,000 in excess thereof and shall be irrevocable by the 
Borrower.

          (b) Any Loans of any Type may be continued as such upon the 
expiration of an Interest Period with respect thereto by compliance by 
the Borrower with the notice provisions contained in 2.4 (a) ; provided 
that no Eurodollar Rate Loan may be continued as such when any Default 
or Event of Default has occurred and is continuing but shall be 
automatically converted to a Base Rate Loan on the last day of the first 
Interest Period relating thereto ending during the continuance of any 
Default or Event of Default of which the officers of the Agent active 
upon the Borrower's account have actual knowledge.

          (c) In the event that the Borrower does not notify the Agent 
of its election hereunder with respect to any Loan, such Loan shall be 
automatically converted to a Base Rate Loan at the end of the applicable 
Interest Period.

          (d) The Borrower may not elect to convert a Base Rate Loan to 
a Eurodollar Rate Loan pursuant to 2.4(a) or elect to continue a 
Eurodollar Rate Loan pursuant to 2.4(b) if, after giving effect thereto, 
there would be greater than four (4) Eurodollar Rate Loans Outstanding. 
Any request for a Eurodollar Rate Loan that would create greater than 
four (4) Eurodollar Rate Loans Outstanding shall be deemed to be a 
request for a Base Rate Loan.

     2.5.     Funds for Loans .

          (a) Subject to 10 and other provisions of this Agreement, not 
later than 11:00 a.m. (Boston time) on the Closing Date, each of the 
Banks will make available to the Agent, at the Agent's Head Office, in 
immediately available funds, the amount of such Bank's Commitment. Upon 
receipt from each Bank of such amount, and upon receipt of the documents 
required by 10 and the satisfaction of the other conditions set forth 
therein, to the extent applicable, the Agent will make available to the 
Borrower the aggregate amount of such Loans made available to the Agent 
by the Banks. The failure or refusal of any Bank to make available to 
the Agent at the aforesaid time and place on the Closing Date the amount 
of its Commitment shall not relieve any other Bank from its several 
obligation hereunder to make available to the Agent the amount of such 
other Bank's Commitment but shall not obligate any other Bank or Agent 
to fund more than its Commitment or to increase its Commitment.

          (b) The Agent may, unless notified to the contrary by any Bank 
prior to the Closing Date, assume that such Bank has made available to 
the Agent on such Closing Date the amount of such Bank's Facility 
Percentage of the Loans to be made on such Closing Date, and the Agent 
may (but it shall not be required to), in reliance upon such assumption, 
make available to the Borrower a corresponding amount. If any Bank makes 
available to the Agent such amount on a date after such Closing Date, 
such Bank shall pay to the Agent on demand an amount equal to the 
product of (i) the average computed for the period referred to in clause 
(iii) below, of the weighted average interest rate paid by the Agent for 
federal funds acquired by the Agent during each day included in such 
period, times (ii) the amount of such Bank's Commitment, times (iii) a 
fraction, the numerator of which is the number of days or portion 
thereof that elapsed from and including such Closing Date to the date on 
which the amount of such Bank's Commitment shall become immediately 
available to the Agent, and the denominator of which is 365.  A 
statement of the Agent submitted to such Bank with respect to any 
amounts owing under this paragraph shall be prima facie evidence of the 
amount due and owing to the Agent by such Bank.

     
     3.     REPAYMENT OF THE LOANS.

     3.1.     Maturity . The Borrower unconditionally promises to pay on 
the Maturity Date, and there shall become absolutely due and payable on 
the Maturity Date, all of the Loans Outstanding on such date, together 
with any and all accrued and unpaid interest and charges thereon.

     3.2.      Optional Repayments of Loans . The Borrower shall have 
the right, at its election, to repay the Outstanding amount of the 
Loans, as a whole or in part, on any Business Day, without penalty or 
premium; provided that the full or partial prepayment of the Outstanding 
amount of any Eurodollar Rate Loans made pursuant to this 3.2 may be 
made only on the last day of the Interest Period relating thereto, 
except as set forth below in this 3.2. The Borrower shall give the Agent 
no later than 10:00 a.m., Boston time, at least three (3) Business Days' 
prior written notice of any prepayment pursuant to this 3.2 of any Base 
Rate Loans and four (4) Eurodollar Business Days, notice of any proposed 
repayment pursuant to this 3.2 of any Eurodollar Rate Loans, specifying 
the proposed date of payment of Loans and the principal amount to be 
paid.  The Agent shall promptly notify each Bank of the principal amount 
of such payment to be received by such Bank. Each such partial 
prepayment of the Loans shall be in an integral multiple of $1,000,000 
and shall be accompanied by the payment of all charges outstanding on 
all Loans and of accrued interest on the principal repaid to the date of 
payment and shall be applied, in the absence of instruction by the 
Borrower, first to the principal of Base Rate Loans and then to the 
principal of Eurodollar Rate Loans.  Notwithstanding anything contained 
herein to the contrary, the Borrower may make a full or partial 
prepayment of a Eurodollar Rate Loan on a date other than the last day 
of the Interest Period relating thereto, if all optional prepayments (in 
whole or in part) on such Loans shall be accompanied by, and the 
Borrower hereby promises to pay, a prepayment fee in an amount 
determined by the Agent in the following manner:

          (a)     Fixed Rate Prepayment Fee.  Borrower acknowledges that 
prepayment or acceleration of a Eurodollar Loan during an Interest 
Period shall result in the Banks incurring additional costs, expenses 
and/or liabilities and that it is extremely difficult and impractical to 
ascertain the extent of such costs, expenses and/or liabilities.  
Therefore, on the date a Eurodollar Rate Loan is prepaid or the date all 
sums payable hereunder become due and payable, by acceleration or 
otherwise ("Prepayment Date"), Borrower will pay to Agent, for the 
account of each Bank, (in addition to all other sums then owing), an 
amount ("Fixed Rate Prepayment Fee") determined by the Agent to be the 
amount, if any, by which (i) the amount of interest which would have 
accrued on the prepaid Eurodollar Rate Loan for the remainder of the 
Interest Period at the rate applicable to such Eurodollar Rate Loan 
exceeds (ii) the amount of interest that would accrue for the same 
period on any readily marketable bond or other obligation of the United 
States of America designated by the Agent in its sole discretion at or 
about the time of such payment, such bond or other obligation of the 
United States of America to be in an amount equal (as nearly as may be) 
to the amount of principal so paid and to have a maturity comparable to 
the remainder of such Interest Period, and the interest to accrue 
thereon to take account of amortization of any discount from par or 
accretion of premium above par at which the same is selling at the time 
of designation.

          (b)     Upon the written notice to Borrower from Agent, 
Borrower shall immediately pay to Agent, for the account of the Banks, 
the Fixed Rate Prepayment Fee.  Such written notice (which shall include 
calculations in reasonable detail) shall, in the absence of manifest 
error, be conclusive and binding on the parties hereto.

          (c)     Borrower understands, agrees and acknowledges the 
following:  (i) no Bank has any obligation to purchase, sell and/or 
match funds in connection with the use of the Eurodollar Rate as a basis 
for calculating the rate of interest on a Eurodollar Rate Loan; (ii) the 
Eurodollar Rate is used merely as a reference in determining such rate; 
and (iii) Borrower has accepted the Eurodollar Rate  as a reasonable and 
fair basis for calculating such rate and a Fixed Rate Prepayment Fee.  
Borrower further agrees to pay the Fixed Rate Prepayment Fee, if any, 
whether or not a Bank elects to purchase, sell and/or match funds.
  
     4.     CERTAIN GENERAL PROVISIONS.

     4.1.     Facility Fees, Arrangement Fee and Agent's Fee . The 
Borrower shall pay to the Agent for the account of each of the Banks 
facility fees in the amount of 50 basis points of such Bank's 
Commitment.  The Borrower shall pay to BankBoston arrangement fees and 
agency fees in the amounts specified in the fee agreement between 
BankBoston and the Borrower dated January 12, 1999. 


     4.2.     Funds for Payments .

          (a)      All payments of principal, interest, closing fees, 
commitment fees and any other amounts due hereunder (other than as 
provided in 4.1, 4.4 and 4.5) or under any of the other Loan Documents, 
and all prepayments, shall be made to the Agent, for the respective 
accounts of the Banks, at the Agent's Head Office, in each case in 
Dollars in immediately available funds.

          (b)  All payments by the Borrower hereunder and under any of 
the other Loan Documents shall be made without setoff or counterclaim 
and free and clear of and without deduction for any taxes, levies, 
imposts, duties, charges, fees, deductions, withholdings, compulsory 
liens, restrictions or conditions of any nature now or hereafter imposed 
or levied by any jurisdiction or any political subdivision thereof or 
taxing or other authority therein unless the Borrower is compelled by 
law to make such deduction or withholding.  If any such obligation is 
imposed upon the Borrower with respect to any amount payable by it 
hereunder or under any of the other Loan Documents, the Borrower shall 
pay to the Agent, for the account of the Banks or (as the case may be) 
the Agent, on the date on which such amount is due and payable hereunder 
or under such other Loan Document, such additional amount in Dollars as 
shall be necessary to enable the Banks or the Agent to receive the same 
net amount which the Banks or the Agent would have received on such due 
date had no such obligation been imposed upon the Borrower. The Borrower 
will deliver promptly to the Agent certificates or other valid vouchers 
for all taxes or other charges deducted from or paid with respect to 
payments made by the Borrower hereunder or under such other Loan 
Document.

     4.3.     Computations . All computations of interest on the Loans 
and of other fees to the extent applicable shall be based on a 360-day 
year and paid for the actual number of days elapsed. Except as otherwise 
provided in the definition of the term "Interest Period" with respect to 
Eurodollar Rate Loans, whenever a payment hereunder or under any of the 
other Loan Documents becomes due on a day that is not a Business Day, 
the due date for such payment shall be extended to the next succeeding 
Business Day, and interest shall accrue during such extension. The 
Outstanding amount of the Loans as reflected on the Records from time to 
time shall (absent manifest error) be considered correct and binding on 
the Borrower unless within thirty (30) Business Days after receipt by 
the Agent or any of the Banks from Borrower of any notice by the 
Borrower of such Outstanding amount, the Agent or such Bank shall notify 
the Borrower to the contrary.

     4.4.     Additional Costs, Etc. If any present or future applicable 
law which expression, as used herein, includes statutes, rules and 
regulations thereunder and interpretations thereof by any competent 
court or by any governmental or other regulatory body or official 
charged with the administration or the interpretation thereof and 
requests, directives, instructions and notices at any time or from time 
to time hereafter made upon or otherwise issued to any Bank or the Agent 
by any central bank or other fiscal, monetary or other authority 
(whether or not having the force of law), shall:

          (a)  subject any Bank or the Agent to any tax, levy, impost, 
duty, charge, fee, deduction or withholding of any nature with respect 
to this Agreement, the other Loan Documents, such Bank's Commitment or 
the Loans (other than taxes based upon or measured by the income or 
profits of such Bank or the Agent), or

          (b)  materially change the basis of taxation (except for 
changes in taxes on income or profits) of payments to any Bank of the 
principal of or the interest on any Loans or any other amounts payable 
to any Bank under this Agreement or the other Loan Documents, or

          (c)  impose or increase or render applicable (other than to 
the extent specifically provided for elsewhere in this Agreement) any 
special deposit, reserve, assessment, liquidity, capital adequacy or 
other similar requirements (whether or not having the force of law) 
against assets held by, or deposits in or for the account of, or loans 
by, or commitments of an office of any Bank, or

          (d)  impose on any Bank any other conditions or requirements 
with respect to this Agreement, the other Loan Documents, the Loans, the 
Commitment, or any class of loans or commitments of which any of the 
Loans or the Commitment forms a part;

and the result of any of the foregoing is

          (i) to increase the cost to such Bank of making, funding, 
issuing, renewing, extending or maintaining any of the Loans or such 
Bank's Commitment, or

          (ii) to reduce the amount of principal, interest or other 
amount payable to such Bank or the Agent hereunder on account of the 
Commitments or any of the Loans, or

          (iii) to require such Bank or the Agent to make any payment or 
to forego any interest or other sum payable hereunder, the amount of 
which payment or foregone interest or other sum is calculated by 
reference to the gross amount of any sum receivable or deemed received 
by such Bank or the Agent from the Borrower hereunder, 

then, and in each such case, the Borrower will, upon demand made by such 
Bank or (as the case may be) the Agent at any time and from time to time 
and as often as the occasion therefor may arise, pay to such Bank or the 
Agent, to the extent permitted by law, such additional amounts as will 
be sufficient to compensate such Bank or the Agent for such additional 
cost, reduction, payment or foregone interest or other sum.

     4.5.     Capital Adequacy. If any present or future law, 
governmental rule, regulation, policy, guideline or directive (whether 
or not having the force of law) or the interpretation thereof by a court 
or governmental authority with appropriate jurisdiction affects the 
amount of capital required or expected to be maintained by banks or bank 
holding companies and any Bank or the Agent determines that the amount 
of capital required to be maintained by it is increased by or based upon 
the existence of the Loans made or deemed to be made pursuant hereto, 
then such Bank or the Agent may notify the Borrower of such fact, and 
the Borrower shall pay to such Bank or the Agent from time to time on 
demand, as an additional fee payable hereunder, such amount as such Bank 
or the Agent shall determine in good faith and certify in a notice to 
the Borrower to be an amount that will adequately compensate such Bank 
or the Agent in light of these circumstances for its increased costs of 
maintaining such capital. Each Bank and the Agent shall allocate such 
cost increases among its customers in good faith and on an equitable 
basis.

     4.6.     Certificate. A certificate setting forth any additional 
amounts payable pursuant to 4.4 or 4.5 and a brief explanation of such 
amounts which are due, submitted by any Bank or the Agent to the 
Borrower, shall be prima facie evidence that such amounts are due and 
owing.

     4.7.     Indemnity.  In addition to the other provisions of this 
Agreement regarding any such matters, the Borrower agrees to indemnify 
each Bank and to hold each Bank harmless from and against any loss, cost 
or reasonable expense (including loss of anticipated profits) that such 
Bank may sustain or incur as a consequence of (a) a default by the 
Borrower in payment of the principal amount of or any interest on any 
Eurodollar Rate Loans as and when due and payable, including any such 
loss or expense caused by Borrower's breach or other default and arising 
from interest or fees payable by such Bank to lenders of funds obtained 
by it in order to maintain its Eurodollar Rate Loans, (b) a default by 
the Borrower in making conversion after the Borrower has given (or is 
deemed to have given) a Conversion Request, and (c) the making of any 
payment of a Eurodollar Rate Loan or the making of any conversion of a 
Eurodollar Rate Loan to a Base Rate Loan on a day that is not the last 
day of the applicable Interest Period with respect thereto, including 
interest or fees payable by such Bank to lenders of funds obtained by it 
in order to maintain any such Eurodollar Rate Loan.

     4.8.     Interest on Overdue Amounts. Overdue principal and (to the 
extent permitted by applicable law) interest on the Loans and all other 
overdue amounts payable hereunder or under any of the other Loan 
Documents shall bear interest compounded monthly and payable on demand 
at a rate per annum equal to four percent (4%) above the Base Rate until 
such amount shall be paid in full (after as well as before judgment). In 
addition, the Borrower shall pay to the Agent a late charge equal to 
three percent (3%) of any amount of principal and/or interest and/or 
charges on the Loans which is not paid within ten (10) days of the date 
when due.

     4.9     Inability to Determine Eurodollar Rate.  In the event, 
prior to the commencement of any Interest Period relating to any 
Eurodollar Rate Loan, the Agent shall determine that adequate and 
reasonable methods do not exist for ascertaining the Eurodollar Rate 
that would otherwise determine the rate of interest to be applicable to 
any Eurodollar Rate Loan during any Interest Period, the Agent shall 
forthwith give notice of such determination (which shall be conclusive 
and binding on the Borrower) to the Borrower. In such event (a) any 
Conversion Request with respect to Eurodollar Rate Loans shall be 
automatically withdrawn and shall be deemed a request for Base Rate 
Loans, (b) each Eurodollar Rate Loan will automatically, on the last day 
of the then current Interest Period thereof, become a Base Rate Loan, 
and (c) the obligations of the Banks to make Eurodollar Rate Loans shall 
be suspended until the Agent determines that the circumstances giving 
rise to such suspension no longer exist, whereupon the Agent shall so 
notify the Borrower.  

     4.10.     Illegality.  Notwithstanding any other provisions herein, 
if any present or future law, regulation, treaty or directive or in the 
interpretation or application thereof shall make it unlawful for any 
Bank to make or maintain Eurodollar Rate Loans, such Bank shall 
forthwith give notice of such circumstances to the Borrower and 
thereupon (a) the commitment of such Bank to make Eurodollar Rate Loans 
or convert Loans of another Type to Eurodollar Rate Loans shall 
forthwith be suspended and (b) the Eurodollar Rate Loans then 
Outstanding shall be converted automatically to Base Rate Loans on the 
last day of each Interest Period applicable to such Eurodollar Rate 
Loans or within such earlier period as may be required by law. The 
Borrower hereby agrees promptly to pay to the Agent for the account of 
such Bank, upon demand, any additional amounts necessary to compensate 
such Bank for any costs incurred by such Bank in making any conversion 
in accordance with this 4.10, including any interest or fees payable by 
such Bank to lenders of funds obtained by it in order to make or 
maintain its Eurodollar Rate Loans hereunder.

     4.11.     Replacement of Banks.  If any of the Banks shall make a 
notice or demand upon the Borrower pursuant to 4.4, 4.5, or 4.10 based 
on circumstances or laws which are not generally applicable to the Banks 
organized under the laws of the United States or any State thereof, the 
Borrower shall have the right to replace such Bank with an Eligible 
Assignee selected by the Borrower and approved by the Agent.  In such 
event the assignment shall take place on a date set by the Agent at 
which time the assigning Bank and the Eligible Assignee shall enter into 
an Assignment and Acceptance as contemplated by 18.1 (and clause (d) 
thereof shall not be applicable) and the assigning Bank shall receive 
from the Eligible Assignee or the Borrower a sum equal to the 
Outstanding principal amount of the Loans owed to the assigning Bank 
together with accrued interest thereon allocated to the assigning Bank.

     5.     UNENCUMBERED PROPERTIES; NO LIMITATION ON RECOURSE.

     5.1.     Listing of Unencumbered Properties .  The Borrower 
represents and warrants that each of the Real Estate Assets listed on 
Schedule 1.1 will on the Closing Date satisfy all of the conditions set 
forth in the definition of Unencumbered Property.  From time to time 
during the term of this Agreement additional Real Estate Assets may 
become Unencumbered Properties and certain Real Estate Assets which 
previously satisfied the conditions set forth in the definition of 
Unencumbered Property may cease to be Unencumbered Properties by virtue 
of property dispositions, creation of Liens or other reasons.  There 
shall be attached to each Compliance Certificate delivered pursuant to 
7.4(d) or 7.12 an updated listing of the Unencumbered Properties relied 
upon by the Borrower in computing the Value of All Unencumbered 
Properties and the Unencumbered Net Operating Income stated in such 
Compliance Certificate.

     5.2.      Waivers by Requisite Banks.  If any Real Estate Asset 
fails to satisfy any of the requirements contained in the definition of 
Unencumbered Property then the applicable Real Estate Asset may 
nevertheless be deemed to be Unencumbered Property hereunder if the 
Requisite Banks grant the necessary waivers and vote to accept such Real 
Estate Asset as an Unencumbered Property.

     5.3.     Rejection of Unencumbered Properties.  If at any time the 
Agent determines that any Real Estate Asset listed as an Unencumbered 
Property by the Borrower does not satisfy all of the requirements of the 
definition of Unencumbered Property (to the extent not waived by the 
Requisite Banks pursuant to 5.2) it may reject an Unencumbered Property 
by notice to the Borrower and if the Agent so requests the Borrower 
shall revise the applicable Compliance Certificate to reflect the 
resulting change in the Value of All Unencumbered Properties and the 
Unencumbered Net Operating Income.

     5.4.     Change in Circumstances.  If at any time during the term 
of this Agreement Borrower becomes aware that any of the representations 
contained in 6 are no longer accurate with respect to any Unencumbered 
Property, it will promptly so notify the Agent and either request a 
waiver pursuant to 5.2 or confirm that such Real Estate Asset is no 
longer an Unencumbered Property.  If any waiver so requested is not 
granted by the Requisite Banks within ten (10) Business Days the Agent 
shall reject the applicable Unencumbered Property pursuant to 5.3.

     5.5.     No Limitation on Recourse. The Obligations are full 
recourse obligations of the Borrower and, to the extent provided in the 
applicable Guaranty, of the Guarantors, and all of their respective Real 
Estate Assets and other properties shall be available for the 
indefeasible payment in full in cash and performance of the Obligations.  
Notwithstanding anything to the contrary contained herein, the trustees 
of Liberty Property Trust shall have no personal liability of any nature 
under this document.  The Agent and the Banks shall look solely to the 
assets of Liberty Property Trust to satisfy any liability or recourse 
against Liberty Property Trust hereunder.

     5.6.     Additional Guarantor Subsidiaries.  If Borrower desires 
that a Real Estate Asset owned by a Related Company which is not 
previously a Guarantor Subsidiary become an Unencumbered Property, then 
provided that the applicable Related Company is at least 85% owned by 
Borrower, such Related Company may become a Guarantor Subsidiary upon 
delivery to the Agent the following, all in form and substance 
satisfactory to the Agent: (a) a Guaranty in substantially the form of 
the Guaranty executed and delivered by the Guarantor Subsidiaries prior 
to the Closing Date, (b) good standing certificates, general partner 
certificates, secretary certificates, opinions of counsel and such other 
documents as may be reasonably requested by the Agent.  The Agent shall 
provide copies of said documents to the Banks.

or groundwater contamination, may have come to be located on; and (v) to 
the best of Borrower's knowledge, any Hazardous Materials that have been 
generated on any of the Real Estate have been transported off-site only 
by carriers having an identification number issued by the EPA, treated 
or disposed of only by treatment or disposal facilities maintaining 
valid permits as required under applicable Environmental Laws, which 
transporters and facilities have been and are, to the best of the 
Borrower's knowledge, operating in material compliance with such permits 
and applicable Environmental Laws. Notwithstanding that any 
representation contained herein may be limited to the knowledge of the 
Borrower, any such limitation shall not affect the covenants specified 
in 7.10 or elsewhere in this Agreement.

          (d)  None of the Real Estate is or shall be subject to any 
applicable environmental clean-up responsibility law or environmental 
restrictive transfer law or regulation, solely by virtue of the

Loan Documents are true and correct in all material respects.

     6.21.     Buildings on the Unencumbered Properties.  Except as set 
forth on Schedule 6.21, to the best of Borrower's knowledge there are no 
material defects in the roof, foundation, structural elements and 
masonry walls of the Buildings on the Unencumbered Properties or their 
heating, ventilating and air conditioning, electrical, sprinkler, 
plumbing or other mechanical systems which would materially decrease the 
value of such Unencumbered Property.

     6.22.  Year 2000 Compliance. The Borrower has (i) reviewed the 
areas within its business and operations which could be adversely 
affected by failure to become "Year 2000 Compliant" (that is that 
computer application, imbedded microchips and other systems used by the 
Borrower or its material vendors or property managers, will be able 
properly to recognize and perform date sensitive functions involving 
certain dates prior to and any date after December 31, 1999; (ii) 
developed a detailed plan and timetable to become Year 2000 Compliant in

believes that it will become Year 2000 Compliant on a timely basis 
except to the extent that a failure to do so will not have a Material 
Adverse Effect.

or of any obligations issued thereunder to accelerate the maturity 
thereof, and in any event, such failure shall continue for thirty (30)

debt, dissolution or liquidation or similar law of any jurisdiction, now 
or hereafter in effect, or shall take any action to authorize or in 
furtherance of any of the foregoing, or if any such petition or 
application shall be filed or any such case or other proceeding shall be 
commenced against any such Person and such Person shall indicate its 
approval thereof, consent thereto or acquiescence therein or any of the 
events described in this paragraph shall occur with respect to any other 
Related Company or any Permitted Joint Venture and such event shall have 
a Material Adverse Effect;

          (h)  a decree or order is entered appointing any such trustee,

involuntary case under federal bankruptcy laws as now or hereafter 
constituted or any of the events described in this paragraph shall occur 
with respect to any other Related Company or any Permitted Joint Venture 
and such event shall have a Material Adverse Effect;

          (i)  there shall remain in force, undischarged, unsatisfied 
and unstayed, for more than thirty days, whether or not consecutive, any 
uninsured final judgment against the Borrower that, with other 
outstanding uninsured final judgments, undischarged, against the 
Borrower, the Company or any of the Related Companies plus the amount of 
any defaulted Recourse Indebtedness under paragraph (f) of this 12.1, 
exceeds in the aggregate $30,000,000.00;

          (j)  if any of the Loan Documents or any material provision of 
any Loan Documents shall be unenforceable, cancelled, terminated, 
revoked or rescinded otherwise than in accordance with the terms thereof 
or with the express prior written agreement, consent or approval of the 
Agent, or any action at law, suit or in equity or other legal proceeding

Indebtedness of the Borrower to any Bank (other than the Obligations) 
and/or relating to any Permitted Lien (other than the Obligations) 
within any applicable period of grace provided for in such agreement, 
document or instrument;

          (m)  any "Event of Default", as defined in any of the other 
Loan Documents, in the Revolving Credit Agreement or in the Subordinated 
Debenture Indenture, shall occur; then, and in any such event, so long 
as the same may be continuing, the Agent may, and upon the request of 
the Requisite Banks shall, by notice in writing to the Borrower declare 
all amounts owing with respect to this Agreement, the Notes and the 
other Loan Documents to be, and they shall thereupon forthwith become, 
immediately due and payable without presentment, demand, protest or 
other notice of any kind, all of which are hereby expressly waived by 
the Borrower; provided that in the event of any Event of Default 
specified in 12.1(g) or 12.1(h), all such amounts shall become 
immediately due and payable automatically and without any requirement of 
notice from the Agent or action by the Requisite Banks.

     12.2.      Remedies.  In case any one or more of the Events of 
Default shall have occurred, and whether or not the Requisite Banks 
shall have accelerated the maturity of the Loans pursuant to 12.1, each 
Bank, if owed any amount with respect to the Loans, may, with the 
consent of the Requisite Banks, direct the Agent to proceed to protect 
and enforce the rights and remedies of the Agent and the Banks under 
this Agreement, the Notes or any of the other Loan Documents by suit in 
equity, action at law or other appropriate proceeding, whether for the 
specific performance of any covenant or agreement contained in this 
Agreement and the other Loan Documents or any instrument pursuant to 
which the Obligations are evidenced and, if any amount shall have become 
due, by declaration or otherwise, to proceed to enforce the payment 
thereof or any other legal or equitable right of such Bank. No remedy 
herein conferred upon any Bank or the Agent or the holder of any Note is 
intended to be exclusive of any other remedy and each and every remedy 
shall be cumulative and shall be in addition to every other remedy given 
hereunder or now or hereafter existing at law or in equity or by statute 
or any other provision of law.

     12.3.     Distribution of Enforcement Proceeds.  In the event that, 
following the occurrence or during the continuance of any Default or 
Event of Default, the Agent or any Bank as the case may be, receives any 
monies in connection with the enforcement of any of the Loan Documents, 
such monies shall be distributed for application as follows:

          (a)  First, to the payment of, or (as the case may be) the 
reimbursement of the Agent for or in respect of all reasonable costs, 
expenses, disbursements and losses which shall have been incurred or 
sustained by the Agent in connection with the collection of such monies 
by the Agent, for the exercise, protection or enforcement by the Agent 
of all or any of the rights, remedies, powers and privileges of the 
Agent or the Banks under this Agreement or any of the other Loan 
Documents or in support of any provision of adequate indemnity to the 
Agent against any taxes or liens which by law shall have, or may have, 
priority over the rights of the Agent to such monies;

          (b)  Second, to all other Obligations in such order or 
preference as the Requisite Banks may determine; provided, however, that 
distribution in respect of such Obligations shall be made among the 
Banks pro rata in accordance with each Bank's respective Facility 
Percentage; and provided, further, that the Agent may in its discretion 
make proper allowance to take into account any Obligations not then due 
and payable;

          (c)  Third, upon payment and satisfaction in full or other 
provisions for payment in full satisfactory to the Requisite Banks and 
the Agent of all of the obligations, and to the payment of any 
obligations required to be paid pursuant to 9-504(1)(c) of the Uniform 
Commercial Code of the Commonwealth of Massachusetts; and

          (d)  Fourth, the excess, if any, shall be returned to the 
Borrower or to such other Persons as are legally entitled thereto.

     13.     SETOFF.  During the continuance of any Event of Default, 
any deposits (general or specific, time or demand, provisional or final, 
regardless of currency, maturity, or the branch of where such deposits 
are held) or other sums credited by or due from any of the Banks to the 
Borrower and any securities or other property of the Borrower in the 
possession of such Bank may be applied to or set off against the payment 
of Obligations and any and all other liabilities, direct, or indirect, 
absolute or contingent, due or to become due, now existing or hereafter 
arising, of the Borrower to such Bank. Each of the Banks agrees with 
each other Bank that (a) if an amount to be set off is to be applied to 
Indebtedness of the Borrower to such Bank, other than Indebtedness 
evidenced by the Notes held by such Bank, such amount shall be applied 
ratably to such other Indebtedness and to the Indebtedness evidenced by 
all such Notes held by such Bank, and (b) if such Bank shall receive 
from the Borrower, whether by voluntary payment, exercise of the right 
of setoff, counterclaim, cross action, enforcement of the claim 
evidenced by the Notes held by such Bank by proceedings against the 
Borrower at law or in equity or by proof thereof in bankruptcy, 
reorganization, liquidation, receivership or similar proceedings, or 
otherwise, and shall retain and apply to the payment of the Note or 
Notes held by such Bank any amount in excess of its ratable portion of 
the payments received by all of the Banks with respect to the Notes held 
by all of the Banks, such Bank will make such disposition and 
arrangements with the other Banks with respect to such excess, either by 
way of distribution, pro tanto assignment of claims, subrogation or 
otherwise as shall result in each Bank receiving in respect of the Notes 
held by it its proportionate payment as contemplated by this Agreement; 
provided that if all or any part of such excess payment is thereafter 
recovered from such Bank, such disposition and arrangements shall be 
rescinded and the amount restored to the extent of such recovery, but 
without interest.

     14.     THE AGENT.

     14.1.     Authorization .  The Agent is authorized to take such 
action on behalf of each of the Banks and to exercise all such powers as 
are hereunder and under any of the other Loan Documents and any related 
documents delegated to the Agent, together with such powers as are 
reasonably incident thereto, provided that no duties or responsibilities 
not expressly assumed herein or therein shall be implied to have been 
assumed by the Agent. The relationship between the Agent and the Banks 
is and shall be that of agent and principal only, and nothing contained 
in this Agreement or any of the other Loan Documents shall be construed 
to constitute the Agent as a trustee for any Bank.

     14.2.     Employees and Agents .  The Agent may exercise its powers 
and execute its duties by or through employees or agents and shall be 
entitled to take, and to rely on, advice of counsel concerning all 
matters pertaining to its rights and duties under this Agreement and the 
other Loan Documents. The Agent may utilize the services of such Persons 
as the Agent in its sole discretion may reasonably determine, and all 
reasonable fees and expenses of any such Persons shall be paid by the 
Borrower.

     14.3.     No Liability .  Neither the Agent nor any of its 
shareholders, directors, officers or employees nor any other Person 
assisting them in their duties nor any agent or employee thereof, shall 
be liable for any waiver, consent or approval given or any action taken, 
or omitted to be taken, in good faith by it or them hereunder or under 
any of the other Loan Documents, or in connection herewith or therewith, 
or be responsible for the consequences of any oversight or error of 
judgment whatsoever, except that the Agent or such other Person, as the 
case may be, may be liable for losses due to its willful misconduct or 
gross negligence.

     14.4.     No Representations .  The Agent shall not be responsible 
for the execution or validity or enforceability of this Agreement, the 
Notes, any of the other Loan Documents or any instrument at any time 
constituting, or intended to constitute, collateral security for the 
Notes, or for the value of any such collateral security or for the 
validity, enforceability or collectability of any such amounts owing 
with respect to the Notes, or for any recitals or statements, warranties 
or representations made herein or in any of the other Loan Documents or 
in any certificate or instrument hereafter furnished to it by or on 
behalf of the Borrower, or be bound to ascertain or inquire as to the 
performance or observance of any of the terms, conditions, covenants or 
agreements herein or in any instrument at any time constituting, or 
intended to constitute, collateral security for the Notes. The Agent 
shall not be bound to ascertain whether any notice, consent, waiver or 
request delivered to it by the Borrower or any holder of any of the 
Notes shall have been duly authorized or is true, accurate and complete. 
The Agent has not made nor does it now make any representations or 
warranties, express or implied, nor does it assume any liability to the 
Banks, with respect to the credit worthiness or financial condition of 
the Borrower. Each Bank acknowledges that it has, independently and 
without reliance upon the Agent or any other Bank, and based upon such 
information and documents as it has deemed appropriate, made its own 
credit analysis and decision to enter into this Agreement. Each Bank has 
been independently represented by separate counsel on all matters 
regarding this Agreement.

     14.5.     Payments .

          (a)  A payment by the Borrower to the Agent hereunder or any 
of the other Loan Documents for the account of any Bank shall constitute 
a payment to such Bank subject to the pro rata rights to repayment based 
upon the Facility Percentage of each Bank. The Agent agrees promptly to 
distribute to each Bank such Bank's pro rata share of payments received 
by the Agent for the account of the Banks except as otherwise expressly 
provided herein or in any of the other Loan Documents. 

          (b)  If in the opinion of the Agent the distribution of any 
amount received by it in such capacity hereunder, under the Notes or 
under any of the other Loan Documents might involve it in liability, it 
may refrain from making distribution until its right to make 
distribution shall have been adjudicated by a court of competent 
jurisdiction. If a court of competent jurisdiction shall adjudge that 
any amount received and distributed by the Agent is to be repaid, each 
Person to whom any such distribution shall have been made shall either 
repay to the Agent its proportionate share of the amount so adjudged to 
be repaid or shall pay over the same in such manner and to such Persons 
as shall be determined by such court.

          (c)  Notwithstanding anything to the contrary contained in 
this Agreement or any of the other Loan Documents, any Bank that fails 
(i) to make available to the Agent its pro rata share of any Loan or 
(ii) to comply with the provisions of 13 with respect to making 
dispositions and arrangements with the other Banks, where such Bank's 
share of any payment received, whether by setoff or otherwise, is in 
excess of its pro rata share of such payments due and payable to all of 
the Banks, in each case as, when and to the full extent required by the 
provisions of this Agreement, or to adjust promptly such Bank's 
outstanding principal and its pro rata Facility Percentage as provided 
in 2.1 hereof, shall be deemed delinquent (a "Delinquent Bank") and 
shall be deemed a Delinquent Bank until such time as such delinquency is 
satisfied.  A Delinquent Bank shall be deemed to have assigned any and 
all payments due to it from the Borrower, whether on account of 
Outstanding Loans, interest, fees or otherwise, to the remaining 
nondelinquent Banks for application to, and reduction of, their 
respective pro rata shares of all Outstanding Loans.  The Delinquent 
Bank hereby authorizes the Agent to distribute such payments to the 
nondelinquent Banks in proportion to their respective pro rata shares of 
all Outstanding Loans. A Delinquent Bank shall be deemed to have 
satisfied in full a delinquency when and if, as a result of application 
of the assigned payments to all Outstanding Loans of the nondelinquent 
Banks, the Banks' respective pro rata shares of all Outstanding Loans 
have returned to those in effect immediately prior to such delinquency 
and without giving effect to the nonpayment causing such delinquency.

     (d) If any amount which the Agent is required to distribute to the 
Banks pursuant to this 14.5 is actually distributed to any Bank on a 
date which is later than the first Business Day following the Agent's 
receipt of the corresponding payment from the Borrower, the Agent shall 
pay to such Bank on demand an amount equal to the product of (i) the 
average computed for the period referred to in clause (iii) below, of 
the weighted average interest rate paid by the Agent for federal funds 
acquired by the Agent during each day included in such period, times 
(ii) the amount of such late distribution to such Bank, times (iii) a 
fraction, the numerator of which is the number of days or portion 
thereof that elapsed from and including the second Business Day after 
the Agent's receipt of such corresponding payment from the Borrower to 
the date on which the amount so required to be distributed to such Bank 
actually is distributed, and the denominator of which is 365.

     14.6.     Holders of Notes.  The Agent may deem and treat the payee 
of any Note as the absolute owner or purchaser thereof for all purposes 
hereof until it shall have been furnished in writing with a different 
name by such payee or by a subsequent holder assignee or transferee.

     14.7.     Indemnity.  The Banks ratably agree hereby to indemnify 
and hold harmless the Agent from and against any and all claims, actions 
and suits (whether groundless or otherwise), losses, damages, costs, 
expenses (including any expenses for which the Agent has not been 
reimbursed by the Borrower as required by 15), and liabilities of every 
nature and character arising out of or related to this Agreement, the 
Notes, or any of the other Loan Documents or the transactions 
contemplated or evidenced hereby or thereby, or the Agent's actions 
taken hereunder or thereunder, except to the extent that any of the same 
shall be directly caused by the Agent's willful misconduct or gross 
negligence.

     14.8.     Agent as Bank.  In its individual capacity, BankBoston 
shall have the same obligations and the same rights, powers and 
privileges in respect to its Commitment and the Loans made by it, and as 
the holder of any of the Notes as it would have were it not also the 
Agent.

     14.9.     Resignation.  The Agent may resign at any time by giving 
sixty (60) days, prior written notice thereof to the Banks and the 
Borrower.  Upon any such resignation, the Requisite Banks shall have the 
right to appoint a successor Agent.  Unless a Default or Event of 
Default shall have occurred and be continuing, appointment of such 
successor Agent shall be subject to the reasonable approval of the 
Borrower.  If no successor Agent shall have been so appointed by the 
Requisite Banks and shall have accepted such appointment within thirty 
(30) days after the giving of notice of resignation or removal of the 
Borrower has disapproved or failed to approve a successor agent within 
such period, then the retiring Agent may, on behalf of the Banks, 
appoint a successor Agent, which shall be a financial institution having 
a rating of not less than A2/P2 or its equivalent by Standard & Poor's 
Corporation. Upon the acceptance of any appointment as Agent hereunder 
by a successor Agent, such successor Agent shall thereupon succeed to 
and become vested with all the rights, powers, privileges and duties of 
the retiring Agent, and the retiring Agent shall be discharged from its 
duties and obligations as Agent hereunder.  After any retiring Agent's 
resignation, the provisions of this Agreement and the other Loan 
Documents shall continue in effect for its benefit in respect of any 
actions taken or omitted to be taken by it while it was acting as Agent.

     14.10.  Notification of Defaults and Events of Default  and other 
Notices.  Each Bank hereby agrees that, upon learning of the existence 
of a Default or an Event of Default, it shall promptly notify the Agent 
thereof. The Agent hereby agrees that upon receipt of any notice under 
this 14.10, or upon it otherwise learning of the existence of a Default 
or an Event of Default, it shall promptly notify the other Banks of the 
existence of such Default or Event of Default.  The Agent shall also 
promptly provide each Bank with a copy of any notices which the Agent 
receives from the Borrower pursuant to 7.5 or 7.12.

     14.11.  Duties in the Case of Enforcement.  In case one of more 
Events of Default have occurred and shall be continuing, and whether or 
not acceleration of the Obligations shall have occurred, the Agent may, 
with the consent of the Requisite Banks (which consents may be obtained 
orally in emergency situations), and the Agent shall, if (a) so 
requested by the Requisite Banks and (b) the Banks have provided to the 
Agent such additional indemnities and assurances against expenses and 
liabilities as the Agent may reasonably request, proceed to enforce the 
provisions of the Loan Documents and exercise all or any such other 
legal and equitable and other rights or remedies as it may have. The 
Requisite Banks may direct the Agent in writing as to the method and the 
extent of any such enforcement actions, the Banks hereby agreeing to 
indemnify and hold the Agent harmless from all liabilities incurred in 
respect of all actions taken or omitted in accordance with such 
directions, provided that the Agent need not comply with any such 
direction to the extent that the Agent reasonably believes the Agent's 
compliance with such direction to be unlawful or commercially 
unreasonable in any applicable jurisdiction.

     14.12.  Mandatory Resignation of Agent.  In the event that the 
Agent enters into one or more Assignments pursuant to 18 having the 
effect of reducing the Agent's Facility Percentage to less than 10% then 
the Agent shall promptly so notify the Banks.  Upon the written request 
of any Bank whose Facility Percentage exceeds that of the Agent, which 
written request is made within thirty (30) days after the Agent's notice 
that its Facility Percentage is below such minimum level, the Agent 
shall be obligated to resign pursuant to 14.9.  Further, the Agent shall 
be obligated to resign pursuant to 14.9 upon the written request made 
for cause by Banks whose aggregate Facility Percentages constitute at 
least sixty-six percent (66%) of  the total Facility Percentages 
excluding the Facility Percentage of the Bank which is then the Agent 
hereunder.

     15.     EXPENSES.  The Borrower agrees to pay (a) the reasonable 
costs of producing and reproducing this Agreement, the other Loan 
Documents and the other agreements and instruments mentioned herein, (b) 
any taxes (including any interest and penalties in respect thereto) 
payable by the Agent or any of the Banks (other than taxes based upon 
the Agent's or any Bank's net income), including any recording, 
mortgage, documentary or intangibles taxes in connection with the Loan 
Documents, or other taxes payable on or with respect to the transactions 
contemplated by this Agreement, including any taxes payable by the Agent 
or any of the Banks after the Closing Date (the Borrower hereby agreeing 
to indemnify the Banks with respect thereto), (c) all title examination 
costs, appraisal fees, engineers', inspectors' and surveyors' fees, 
recording costs and the reasonable fees, expenses and disbursements of 
the Agent's counsel or any local counsel to the Agent incurred in

hereto or hereunder, (d) the fees, costs, expenses and disbursements of 
the Agent incurred in connection with the preparation, administration or 
interpretation of the Loan Documents and other instruments mentioned 
herein including without limitation, the costs incurred by the Agent in 
connection with its inspection of the Unencumbered Properties, and the 
fees and disbursements of the Agent's counsel and the Borrower's legal 
counsel in preparing documentation, (e) the fees, costs, expenses and 
disbursements of the Agent incurred in connection with the syndication 
and/or participation of the Loans, (f) all reasonable out-of-pocket 
expenses (including reasonable attorneys' fees and costs, which 
attorneys may be employees of any Bank or the Agent and the fees and 
costs of appraisers, engineers, investment bankers, surveyors or other 
experts retained by the Agent or any Bank in connection with any such 
enforcement proceedings) incurred by any Bank or the Agent in connection 
with (i) the enforcement of or preservation of rights under any of the 
Loan Documents against the Borrower or the administration thereof after 
the occurrence of a Default or Event of Default (including, without 
limitation, expenses incurred in any restructuring and/or "workout" of 
the Loans), and (ii) any litigation, proceeding or dispute whether 
arising hereunder or otherwise, in any way related to the Agent's or the 
Bank's relationship with the Borrower, the Company, any Permitted Joint 
Venture or any of the Related Companies, (g) all reasonable fees, 
expenses and disbursements of the Agent incurred in connection with UCC 
searches, and (h) all costs incurred by the Agent in the future in 
connection with its inspection of the Unencumbered Properties. The 
covenants of this 15 shall survive payment or satisfaction of payment of 
amounts owing with respect to the Notes.

     16.     INDEMNIFICATION.  The Borrower agrees to indemnify and hold 
harmless the Agent and the Banks and the shareholders, directors, 
agents, officers, subsidiaries, and affiliates of the Agent and the 
Banks from and against any and all claims, actions or causes of action 
and suits whether groundless or otherwise, and from and against any and 
all Liabilities, losses, settlement payments, obligations, damages and 
expenses of every nature and character arising out of this Agreement or 
any of the other Loan Documents or the transactions contemplated hereby 
or which otherwise arise in connection with the financing including, 
without limitation except to the extent directly caused by the gross 
negligence or willful misconduct of a Bank or the Agent (but such 
limitation on indemnification shall only apply to the Agent or Bank 
being grossly negligent or committing willful misconduct), (a) any 
actual or proposed use by the Borrower of the proceeds of any of the 
Loans, (b) any actual or alleged infringement of any patent, copyright, 
trademark, service mark or similar right of the Borrower, (c) the 
Borrower entering into or performing this Agreement or any of the other 
Loan Documents or (d) with respect to the Borrower and its respective 
properties, the violation of any Environmental Law, the Release or 
threatened Release of any Hazardous Substances or any action, suit, 
proceeding or investigation brought or threatened with respect to any 
Hazardous Substances (including, but not limited to claims with respect 
to wrongful death, personal injury or damage to property), (e) any cost, 
claim liability, damage or expense in connection with any harm the 
Borrower may be found to have caused in the role of a broker, in each 
case including, without limitation, the reasonable fees and 
disbursements of counsel and allocated costs of internal counsel 
incurred in connection with any such investigation, litigation or other 
proceeding. In litigation, or the preparation therefor, the Banks and 
the Agent shall each be entitled to select their own separate counsel 
and, in addition to the foregoing indemnity, the Borrower agrees to pay 
promptly the reasonable fees and expenses of such counsel.  If, and to 
the extent that the obligations of the Borrower under this 16 are 
unenforceable for any reason, the Borrower hereby agrees to make the 
maximum contribution to the payment in satisfaction of such obligations 
which is permissible under applicable law. The provisions of this 16 
shall survive the repayment of the Loans and the termination of the 
obligations of the Banks hereunder and shall continue in full force and 
effect as to the Banks so long as the possibility of any such claim, 
action, cause of action or suit exists.

     17.     SURVIVAL OF COVENANTS, ETC.  All covenants, agreements, 
representations and warranties made herein, in the Notes, in any of the 
other Loan Documents or in any documents or other papers delivered by or 
on behalf of the Borrower or any Guarantor pursuant hereto shall be 
deemed to have been relied upon by the Banks and the Agent, 
notwithstanding any investigation heretofore or hereafter made by it, 
and shall survive the making by the Banks of the Loans, as herein 
contemplated, and shall continue in full force and effect so long as any 
amount due under this Agreement or the Notes or any of the other Loan 
Documents remains outstanding. The indemnification obligations of the 
Borrower provided herein and the other Loan Documents shall survive the 
full repayment of amounts due and the termination of the obligations of 
the Banks hereunder and thereunder to the extent provided herein and 
therein. All statements contained in any certificate or other paper 
delivered to the Agent or any Bank at any time by or on behalf of the 
Borrower pursuant hereto or in connection with the transactions 
contemplated hereby shall constitute representations and warranties by 
the Borrower hereunder.

     18.     ASSIGNMENT; PARTICIPATIONS; ETC.

     18.1.     Conditions to Assignment by Banks.  Except as provided 
herein, each Bank may assign to one or more Eligible Assignees all or a 
portion of its interests, rights and obligations under this Agreement 
(including all or a portion of its Facility Percentage and the same 
portion of the Loans at the time owing to it, and the Notes held by it); 
provided that (a) the Agent shall have given its prior written consent 
to such assignment, which consent shall not be unreasonably withheld or 
delayed, except that such consent shall not be needed with respect to an 
assignment from a Bank to either one of its Affiliated Banks or to 
another Bank hereunder, (b) each such assignment shall be of a portion 
of the assigning Bank's rights and obligations under this Agreement 
relating to a specified Facility Percentage, (c) each assignment shall 
be of Loans in an amount of not less than $10,000,000 (which number will 
be reduced in proportion to any partial prepayment of the Loans pursuant 
to 3.2) that is a whole multiple of $1,000,000, (d) each Bank either 
shall assign all of its Loans and cease to be a Bank hereunder or shall 
retain, free of any such assignment, an amount of its Outstanding Loans 
of not less than $10,000,000 (which number will be reduced in proportion 
to any partial prepayment of the Loans pursuant to 3.2), and (e) the 
parties to such assignment shall execute and deliver to the Agent, for 
recording in the Register (as hereinafter defined), an Assignment and 
Acceptance, substantially in the form of Exhibit E hereto (an 
"Assignment and Acceptance") , together with any Notes subject to such 
assignment.   Upon such execution, delivery, acceptance and recording, 
from and after the effective date specified in each Assignment and 
Acceptance, which effective date shall be at least five (5) Business 
Days after the execution thereof, (i) the assignee thereunder shall be a 
party hereto and, to the extent provided in such Assignment and 
Acceptance, have the rights and obligations of a Bank hereunder, and 
(ii) the assigning Bank shall, to the extent provided in such assignment 
and upon payment to the Agent of the registration fee referred to in 
18.3, be released from its obligations under this Agreement. So long as 
no Default or Event of Default has occurred and is continuing, 
Borrower's consent shall also be required for any assignment to an 
Eligible Assignee which is not at the time a Bank hereunder or one of 
such Bank's Affiliated Banks provided that Borrower's consent shall not 
be unreasonably withheld or delayed and shall not be withheld unless 
Borrower simultaneously designates an alternative Eligible Assignee 
(approved by the Agent) who agrees to accept an assignment of the 
interest which the assigning Bank proposed to assign and pay to such 
assigning Bank a sum equal to the Outstanding balance of principal and 
interest of Loans relating to the Facility Percentage being assigned. 
Assignments by BankBoston shall be exempt from the requirement in clause 
(c) above that assignments be of Loans in an amount which is a whole 
multiple of $1,000,000, the requirement that the effective date be at 
least five days after execution of the Assignment and Acceptance and the 
requirement for Borrower's consent and there shall be no registration 
fee with respect thereto under 18.3.

     18.2.     Certain Representations and Warranties; Limitations; 
Covenants.  By executing and delivering an Assignment and Acceptance, 
the parties to the assignment thereunder confirm to and agree with each 
other and the other parties hereto as follows: (a) other than the 
representation and warranty that it is the legal and beneficial owner of 
the interest being assigned thereby free and clear of any adverse claim, 
the assigning Bank makes no representation or warranty and assumes no 
responsibility with respect to any statements, warranties or 
representations made in or in connection with this Agreement or the 
execution, legality, validity, enforceability, genuineness, sufficiency 
or value of this Agreement, the other Loan Documents or any other 
instrument or document furnished pursuant hereto; (b) the assigning Bank 
makes no representation or warranty and assumes no responsibility with 
respect to the financial condition of the Borrower or any other Person 
primarily or secondarily liable in respect of any of the Obligations, or 
the performance or observance by the Borrower or any other Person 
primarily or secondarily liable in respect of any of the Obligations of 
any of their obligations under this Agreement or any of the other Loan 
Documents or any other instrument or document furnished pursuant hereto 
or thereto; (c) such assignee confirms that it has received a copy of 
this Agreement, together with copies of the most recent financial 
statements referred to in 6.4 and 7.4 and such other documents and 
information as it has deemed appropriate to make its own credit analysis 
and decision to enter into such Assignment and Acceptance; (d) such 
assignee will, independently and without reliance upon the assigning 
Bank, the Agent or any other Bank and based on such documents and 
information as it shall deem appropriate at the time, continue to make 
its own credit decisions in taking or not taking action under this 
Agreement, (e) such assignee represents and warrants that it is an 
Eligible Assignee; (f) such assignee appoints and authorizes the Agent 
to take such action as "Agent" on its behalf and to exercise such powers 
under this Agreement and the other Loan Documents as are delegated to 
the Agent by the terms hereof or thereof, together with such powers as 
are reasonably incidental thereto; (g) such assignee agrees that it will 
perform in accordance with their terms all of the obligations that by 
the terms of this Agreement are required to be performed by it as a 
Bank; and (h) such assignee represents and warrants that it is legally 
authorized to enter into such Assignment and Acceptance.  Each of the 
Syndication Banks shall be subject to the provisions of this 18.2 to the 
same extent as though it were becoming a party to this Agreement as an 
assignee by entering into an Assignment and Acceptance with BankBoston 
effective on the Closing Date.

     18.3     Register.  The Agent shall maintain a copy of each 
Assignment and Acceptance delivered to it and a register or similar list 
(the "Register") for the recordation of the names and addresses of the 
Banks and the Facility Percentages of, and principal amount of the Loans 
owing to the Banks from time to time. The entries in the Register shall 
be conclusive, in the absence of manifest error, and the Borrower, the 
Agent and the Banks may treat each Person whose name is recorded in the 
Register as a Bank hereunder for all purposes of this Agreement. The 
Register shall be available for inspection by the Borrower and the Banks 
at any reasonable time and from time to time upon reasonable prior 
notice.  Upon each such recordation, the assigning Bank agrees to pay to 
the Agent a registration fee in the sum of $2,500.00. The Agent may, 
without action by any other party, amend Schedules 1 and 1.2 hereof to 
reflect the recording of any such assignments.

     18.4.     New Notes.  Upon its receipt of an Assignment and 
Acceptance executed by the parties to such assignment, together with 
each Note subject to such assignment, the Agent shall (a) record the 
information contained therein in the Register, and (b) give prompt 
notice thereof to the Borrower and the Banks (other than the assigning 
Bank). Within five (5) Business Days after receipt of such notice, the 
Borrower, at its own expense, shall execute and deliver to the Agent, in 
exchange for each surrendered Note, a new Note to the order of such 
Eligible Assignee in an amount equal to the amount assumed by such 
Eligible Assignee pursuant to such Assignment and Acceptance and, if the 
assigning Bank has retained some portion of its Loans hereunder, a new 
Note to the order of the assigning Bank in an amount equal to the amount 
retained by it hereunder. Such new Notes shall provide that they are 
replacements for the surrendered Notes and that they do not constitute a 
novation, shall be in an aggregate principal amount equal to the 
aggregate principal amount of the surrendered Notes, shall be dated the 
effective date of such Assignment and Acceptance and shall otherwise be 
in substantially the form of the assigned Notes.  Within five (5) days 
of issuance of any new Notes pursuant to this 18.4, the Borrower shall 
deliver an opinion of counsel, addressed to the Banks and the Agent, 
relating to the due authorization, execution and delivery of such new 
Notes and the legality, validity and binding effect thereof, and that 
the Obligations evidenced by the new Notes have the same validity, 
enforceability and priority as if given on the Closing Date, in form and 
substance satisfactory to the Banks. The surrendered Notes shall be 
cancelled and returned to the Borrower.

     18.5.     Participations.  Each Bank may sell participations to one 
or more banks or other entities in a portion of such Bank's rights and 
obligations under this Agreement and the other Loan Documents not to 
exceed forty-nine percent (49%) of its Facility Percentage; provided 
that (a) the Agent shall have given its prior written consent to such 
participation, which consent shall not be unreasonably withheld or 
delayed, except that any Bank may sell participations to its Affiliated 
Banks without such consent, (b) each such participation, other than 
participations to its Affiliated Banks or to another Bank hereunder, 
shall be in an amount of not less than $10,000,000 that is a whole 
multiple of $1,000,000, (c) any such sale or participation shall not 
affect the rights and duties of the selling Bank hereunder to the 
Borrower and the Bank shall continue to exercise all approvals, 
disapprovals and other functions of a Bank, (d) the only rights granted 
to the participant pursuant to such participation arrangements with 
respect to waivers, amendments or modifications of the Loan Documents 
shall be the rights to approve the vote of the Bank as to waivers, 
amendments or modifications that would reduce the principal of or the 
interest rate on any Loans, extend the term or increase the amount of 
the Commitment of such Bank as it relates to such participant, reduce 
the amount of any fees to which such participant is entitled or extend 
any regularly scheduled payment date for principal or interest, provided 
that all approvals affecting a Loan or this Agreement under this clause 
(d) shall be by a fifty-one percent (51%) vote of such Bank's Facility 
Percentage, and (e) no participant which is not a Bank hereunder shall 
have the right to grant further participations or assign its rights, 
obligations or interests under such participation to other Persons 
without the prior written consent of the Agent. The Agent shall promptly 
advise the Borrower in writing of any such sale or participation.

     18.6.     Pledge by Lender.  Any Bank may at any time pledge all or 
any portion of its interest and rights under this Agreement (including 
all or any portion of its Note) to any of the twelve Federal Reserve 
Banks organized under 4 of the Federal Reserve Act, 12 U.S.C. 341. No 
such pledge or the enforcement thereof shall release the pledgor Bank 
from its obligations hereunder or under any of the other Loan Documents.

     18.7.     No Assignment by Borrower.  The Borrower shall not assign 
or transfer any of its rights or obligations under any of the Loan 
Documents without the prior written consent of each of the Banks, and 
any such attempted assignment shall be null and void.

     18.8.     Disclosure.  The Borrower agrees that in addition to 
disclosures made in accordance with standard banking practices any Bank 
may disclose information obtained by such Bank pursuant to this 
Agreement to assignees or participants and potential assignees or 
participants hereunder.

     19.     NOTICES, ETC.  Except as otherwise expressly provided in 
this Agreement, all notices and other communications made or required to

as contemplated by this Agreement. Notwithstanding the foregoing, (i) 
the rate of interest on and the term or amount of the Notes, (ii) the 
amount of the Commitments of the Banks, (iii) the amount of any fee 
payable to a Bank hereunder, (iv) any provision herein or in any of the 
Loan Documents which expressly requires consent of all the Banks, (v) 
the funding provisions of 11.1 hereof, (vi) the rights, duties and 
obligations of the Agent specified in 14 hereof, and (vii) the 
definition of Requisite Banks, may not be amended without the written 
consent of each Bank affected thereby, nor may the Agent release the 
Borrower or any Guarantor from its liability with respect to the 
Obligations, without first obtaining the written consent of all the 
Banks.  No waiver shall extend to or affect any obligation not expressly 
waived or impair any right consequent thereon. No course of dealing or 
delay or omission on the part of the Agent or any Bank in exercising any 
right shall operate as a waiver thereof or otherwise be prejudicial 
thereto. No notice to or demand upon the Borrower shall entitle the 
Borrower to other or further notice or demand in similar or other 
circumstances.

     26.     SEVERABILITY.  The provisions of this Agreement are 
severable, and if any one clause or provision hereof shall be held 
invalid or unenforceable in whole or in part in any jurisdiction, then 
such invalidity or unenforceability shall affect only such clause or 
provision, or part thereof, in such jurisdiction, and shall not in any 
manner affect such clause or provision in any other jurisdiction, or any 
other clause or provision of this Agreement in any jurisdiction.

     27.     ACKNOWLEDGMENTS.     The Borrower hereby acknowledges that: 
(i) neither the Agent nor any Bank has any fiduciary relationship with, 
or fiduciary duty to, the Borrower arising out of or in connection with 
this Agreement or any of the other Loan Documents; (ii) the relationship 
in connection herewith between the Agent and the Banks, on the one hand, 
and the Borrower, on the other hand, is solely that of debtor and 
creditor and (iii) no joint venture or partnership among any of the 
parties hereto is created hereby or by the other Loan Documents, or 
otherwise exists by virtue of the Facility or the Loans.



     IN WITNESS WHEREOF, the undersigned have duly executed this 
Agreement as a sealed instrument as of the date first set forth above.
