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, 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, 1997,  
consisted of 441 industrial and office properties (the "Properties in  
Operation") totaling approximately 32.5 million leaseable square feet. 
As of December 31, 1997, the Properties in Operation were approximately 
94.6% leased to over 1500 tenants.  As of December 31, 1997, the Company 
also had 43 properties under development (the "Properties Under 
Development" and, together with the Properties in Operation, the 
"Properties"). The Properties Under Development are expected to generate 
approximately 4.1 million leaseable square feet. The Properties are 
located principally within the Southeastern, Mid-Atlantic and Mid-
Western United States.  As of December 31, 1997, the Company also owned 
957 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. The Company is 
obligated to purchase, over a 10-year period ending in 2007, 
approximately 800 acres of land.
 
During the year ended December 31, 1997, through Total Investments (as  
defined below) aggregating $871.5 million, the Company increased its 
total leaseable square footage of industrial and office space  
approximately 57.4% by acquiring 170 properties totaling approximately 
9.5 million leaseable square feet and by developing 20 properties 
totaling approximately 2.9 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, 1997, consisted of 297 
industrial and 144 office properties.  Single tenants occupied 154 of 
the Properties in Operation.  The Company provides a reduced level of 
services in connection with the operation or maintenance of these 
properties.  The remaining 287 of the Properties in Operation were 

     5

occupied by multiple tenants for which the Company renders a range of 
building, operating and maintenance services.  The Company's industrial 
properties consist of a variety of warehouse, distribution, service, 
assembly, light manufacturing and research and development facilities.  
Substantially all of the Company's industrial properties are located in 
suburban, mixed-use developments or business parks.  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 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 91.86% at December 31, 1997.  The units of limited 
partnership interest (the "Units") in the Operating Partnership 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.  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 4.7 million Common Shares on December 31, 
1997.  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, 1997 the Company's principal markets were as follows: 
Southeastern Pennsylvania; New Jersey/Delaware; Lehigh Valley, 
Pennsylvania; Richmond, Virginia; the Baltimore/Washington Corridor; the 
Carolinas; Jacksonville, Florida; Tampa, Florida; South Florida; the 
Minneapolis metropolitan area; and the Detroit metropolitan area. 
 
MANAGEMENT AND EMPLOYEES 
 
The Company's 278 employees (as of February 25, 1998) are under the 
direction of 19 senior executives, who have developed and managed over     
35 million square feet of commercial real estate during the past 25 
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 12 full-service local offices 
in the United States.  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 acquisition and development 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 

     6

Properties and (ii) developing and acquiring high quality properties in 
existing and select new markets.  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 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 higher rental rates and by improving the occupancy 
rates of its portfolio.  
 
NEW LEASES AND LEASE RENEWALS.  In the early 1990's, rental rates in the 
markets in which the Properties are located were flat or decreased as a 
result of recessionary market conditions and an oversupply of commercial 
real estate in such markets. Since that time, rental rates in these 
markets have improved, and as the leases entered into in the early 1990s 
and subsequent years have expired, 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 
higher rental rates.
 
CONTRACTUAL INCREASES.  The Company seeks to generate increased cash 
flow from the Properties in Operation through contractual increases in 
rental rates under its leases.  The leases in effect with respect to the 
Properties in Operation as of December 31, 1997 provide for contractual 
rental increases that are expected to contribute an additional $1.9 
million to the Company's cash flow for the year ending December 31, 
1998.  The Company intends to continue seeking to negotiate contractual 
rent increases that take effect during the terms of its leases. 
 
IMPROVING OCCUPANCIES.  The Company believes that the quality and 
diversity of its tenant base has contributed, and will continue to 
contribute, to the success of its strategy for increasing rental and 
occupancy rates.  The Company targets financially stable tenants in an 
effort to minimize uncertainty relating to the ability of its tenants to 
meet their lease obligations.  The Company's success in maintaining its 
occupancy rates and attracting and retaining tenants is demonstrated in 
part by its renewal rate which was approximately 72.2% for the year 
ended December 31, 1997. 
 
COST CONTROLS.  The Company seeks to monitor and control 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 
(including, in certain instances, an entity affiliated with one or more 
of the Company's senior executives), 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 their long-term values. 
 
     7

ACQUISITIONS 

STRATEGY

The Company seeks to acquire properties consistent with its business 
objectives and strategies.  The Company executes its acquisition 
strategy by purchasing portfolios of properties and individual 
properties as single asset acquisitions.  Portfolios are considered to 
be groups of properties or existing real estate companies within 
existing markets or select new markets.  At times, the Company may 
acquire multiple properties which because of their aggregate size or 
other factors are not considered portfolio acquisitions.  The Company 
has identified the following general categories of properties for 
acquisition:

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

     Entrepreneurial Acquisitions which 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.

     SINGLE-ASSET ACQUISITIONS
     -------------------------

     During the year ended December 31, 1997, the Company completed 78   
acquisitions of this type, aggregating approximately 4.5 million 
leaseable square feet for a Total Investment of $346.7 million.  The 
following sets forth certain information with respect to such 
acquisitions:

     Stabilized Acquisitions.  During the year ended December 31, 1997 
the Company completed acquisitions of 64 stabilized properties 
aggregating approximately 3.5 million leaseable square feet of 
industrial and office space for a Total Investment of $280.5 million.

     Entrepreneurial Acquisitions.  During the year ended December 31, 
1997, the Company completed entrepreneurial acquisitions of 14 
entrepreneurial properties aggregating approximately one million 
leaseable square feet of industrial and office space for a Total 
Investment of $66.2 million.

    PORTFOLIO ACQUISITIONS
    ----------------------

    Portfolio acquisitions may include stabilized, entrepreneurial and 
development properties and are considered to offer opportunities for 
enhanced operating performance as a result of the Company's management 
expertise and financial strength and/or the portfolio's fit within the 
Company's business plan.

     During the year ended December 31, 1997, the Company completed five 
portfolio acquisitions, consisting in the aggregate of 88 stabilized 
properties and four entrepreneurial properties.  In connection with 
these portfolio acquisitions, the Company opened offices to serve its 
new markets in the Detroit and Minneapolis metropolitan areas and South 
Carolina.  The properties acquired in the portfolio acquisitions 
comprise, in the aggregate, approximately 5.0 million leaseable square 
feet for a Total Investment of $381.2 million.  The following sets forth 
certain information with respect to such portfolio acquisitions:

      8

     Detroit Portfolios.  In June 1997, the Company entered the suburban 
Detroit, Michigan market with the acquisition of a portfolio (the "First 
Detroit Portfolio").  The First Detroit Portfolio consisted of 13 
industrial and office properties totaling approximately 1.1 million 
leaseable square feet which were purchased for a Total Investment of 
approximately $131.3 million.  All of these properties were considered 
stabilized acquisitions.

     In September 1997, the Company increased the number of properties 
it owned in the suburban Detroit market by acquiring a second portfolio 
(the "Second Detroit Portfolio").  The Second Detroit Portfolio 
consisted of 28 industrial properties totalling approximately 841,000 
leaseable square feet which were purchased for a Total Investment of 
approximately $45.0 million.  All of these properties were considered 
stabilized acquisitions.

     South Carolina Portfolio.  In May 1997, the Company acquired a 
portfolio consisting of properties located mainly in South Carolina (the 
"South Carolina Portfolio").  The South Carolina Portfolio consisted of 
18 properties totalling approximately 1.4 million leaseable square feet, 
11 of which were considered stabilized acquisitions, three of which were 
considered entrepreneurial acquisitions and four of which were 
considered development properties.  The Total Investment for the 
stabilized and entrepreneurial properties was approximately $57.6 
million.  The development properties comprised approximately 324,000 of 
the 1.4 million leaseable square feet and the Total Investment in the 
development properties was approximately $18.5 million.  In connection 
with the acquisition of the South Carolina Portfolio, the Company is 
also obligated to purchase, over a 10-year period ending in 2007, 
approximately 800 acres of land for commercial development. The purchase 
price of the land is $17.5 million, plus accrued interest at 7.5% per 
annum, payable over 10 years ending in 2007. 

     Minneapolis Portfolio.  In March 1997, the Company acquired a 
portfolio in Minneapolis, Minnesota (the "Minneapolis Portfolio").  All 
of the properties in the portfolio were considered stabilized 
acquisitions and totalled approximately 1.0 million square feet.  The 
Total Investment in the Minneapolis Portfolio was approximately $63.3 
million.  The Company also acquired 25 acres of land for commercial 
development, which the Company anticipates to be capable of supporting, 
as and when developed, approximately 180,000 leaseable square feet of 
office or industrial space.  The purchase price of the land was $2.9 
million, in addition to the purchase price of the industrial and office 
properties in the portfolio.

     Horsham Portfolio.  In November 1997, the Company acquired a 
portfolio of properties in the Pennsylvania Business Campus in Horsham, 
Pennsylvania (the "Horsham Portfolio").  The Horsham Portfolio consisted 
of 21 industrial and office properties, 20 of which were considered 
stabilized and one of which was considered entrepreneurial.  The 
properties, totaling approximately one million leaseable square feet, 
were purchased for a Total Investment of $84.0 million.

DEVELOPMENT 
 
STRATEGY.  The Company pursues selective development opportunities  
focusing primarily on high-quality suburban industrial and office  
properties within its existing markets.  The Company's development  
activities fall into two categories: build-to-suit projects and projects  

      9

built for inventory.  The Company develops build-to-suit (approximately 
70% pre-leased) 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, 
1997, the Company completed 11 build-to-suit and nine inventory  
projects, totalling approximately 2.9 million square feet of leaseable 
space and representing a Total Investment of approximately $143.5 
million.  As of December 31, 1997, the completed development properties 
were 97.6% leased. 
 
PROPERTIES UNDER DEVELOPMENT.  As of December 31, 1997, the Company was 
developing 43 properties which, upon completion, are expected to 
generate approximately 4.1 million leaseable square feet.  Approximately 
42.5% of such leaseable space was pre-leased as of December 31, 1997.  
The Properties Under Development as of December 31, 1997 are expected to 
represent a Total Investment of $304.9 million.  Five of these 
properties are 100% pre-leased under net leases as build-to-suit 
projects. There can be no assurance that any of the Properties Under 
Development will be completed, or that the Company's budgets or 
estimates of construction costs or time periods necessary to complete 
construction of such Properties, will be realized.  The Company is 
scheduled to complete development of 20 properties (totaling 2.5 million 
leaseable square feet) in the year ended December 31, 1998 representing 
a Total Investment of $162.7 million. 
 
LAND.  As of December 31, 1996, the Company owned 1,012 acres of land 
for development, all zoned for commercial use. During the year ended 
December 31, 1997, the Company purchased an additional 280 acres of land 
for development, utilized 283 acres in development projects and sold 52 
acres.  Substantially all of the remaining 957 acres owned as of 
December 31, 1997 is located adjacent to or within existing industrial 
or business parks with site improvements, such as public sewers, water 
and utilities, available for service.  The Company anticipates that the 
land would support, as and when developed, approximately nine million 
leaseable square feet.  The Company's Total Investment in land held for 
development as of December 31, 1997 was $61.9 million.  In connection 
with the acquisition of the South Carolina Portfolio, the Company is 
obligated to purchase, over a 10-year period ending in 2007, 
approximately 800 acres of land for commercial development, which the 
Company believes is capable of supporting, as and when developed, 
approximately eight million leaseable square feet of industrial or 
office space.  Substantially all of the acreage the Company is obligated 
to purchase is located in the Charleston, Columbia and Greenville, South 
Carolina 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 operations include 
four 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 committed to loans in 1996 to two 

      10

affiliates for development projects.  As of December 31, 1997, only one 
of these loans, with a balance of $5.5 million, remained outstanding.  
 
SUBSEQUENT ACTIVITIES 
 
Since December 31, 1997, the Company has purchased 23 industrial and 
office properties containing approximately 1.6 million leaseable square 
feet for a Total Investment of $131.7 million. In addition, the Company 
has completed development of four industrial and office properties 
containing approximately 207,000 leaseable square feet for a Total 
Investment of $15.2 million. 
 
The Company intends to pursue its acquisition and development 
strategies.  The Company is currently in various stages of discussions  
and negotiations with respect to acquisition and  development projects 
totaling over $400.0 million of Total Investment.  The consummation of 
these or any other future acquisitions or developments, if any, and the 
pace at which acquisitions may be made and developments completed, 
cannot be assured. 
 
COMPETITION 
 
The Company faces competition as a buyer, developer and lessor of  
properties and will likely face competition as an eventual seller of  
properties to the extent that properties are sold.  The Company may be  
competing with other owners and developers with greater resources and  
whose management may have more experience than the Company's officers  
and trustees.  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 acquisition strategy.  Like the Company, many of the  
potentially competing purchasers can use their own securities in making  
acquisitions.  Additionally, 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 at the Properties or any newly acquired or developed property and 
on the rents charged for the Properties in Operation.  However, the 
Company believes that its capital base, its existing sources of credit 
and its access, as a publicly owned entity, to the public capital 
markets to raise funds during periods when conventional sources of 
financing may be unavailable or relatively more expensive will provide 
the Company with competitive advantages.    Further, 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. 
 
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  

     11

and the liability of the owner or operator therefor 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 in Operation 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, George F. Congdon and David C. Hammers, 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

      21

indicated, the high and low closing prices of the Common Shares on the

As of February 25, 1998, the Common Shares were held by 561 holders of 
record.  Since its initial public offering, the Company has paid regular 
and uninterrupted dividends. 

Although the Company currently anticipates that comparable cash  
dividends will continue to be paid in the future, the payment of future  
dividends by the Company will be at the discretion of the Board of  
Trustees and will depend on numerous factors including the Company's  
cash flow, its financial condition, capital requirements, annual  
distribution requirements under the REIT provisions of the Internal  
Revenue Code of 1986, as amended, and such other factors as the Board of  
Trustees deems relevant.

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

In 1997, the Company continued to pursue acquisition and development 
opportunities and 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.

     24

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 Company's Properties in 
Operation.  In addition, the Company's continued growth is dependent 
upon its ability to maintain property occupancy rates and increase 
rental rates on the Properties in Operation and to continue development 
and acquisition of additional properties.  The occupancy rate of the 
Properties in Operation has increased during the last two years and was 
94.6% at December 31, 1997.  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 
earnings from rental operations.  

The Company also will seek to achieve growth in earnings from rental 
operations through (i) the acquisition of additional rental properties 
in its primary markets; (ii) the expansion into selected new markets; 
and (iii) the maintenance and expansion of its development pipeline.

The Company acquired 170 properties consisting of 9.5 million leaseable 
square feet during 1997 as compared to the acquisition of 33 properties 
consisting of 2.4 million leaseable square feet during 1996.  The 
Company anticipates continuing to pursue the acquisition of rental 
properties but notes that the competition for acquisitions has been 
increasing and that the initial return may be decreasing.  The Company 
will seek through its active pursuit of acquisitions in its multiple 
markets to continue to achieve attractive returns on acquisitions.

The Company also increased its level of development activity in 1997.  
In 1997, the Company completed 20 projects totalling approximately 2.9 
million leaseable square feet for a Total Investment of $143.5 million.  
In addition, as of December 31, 1997, the Company had 43 properties 
expected to generate approximately 4.1 million leaseable square feet of 
suburban office and industrial space under development which represents 
an estimated Total Investment of $304.9 million.  The Company expects to 
complete the Properties Under Development over the next eight quarters.

The Company continued to strengthen its balance sheet in 1997 by 
accessing both the public and private equity markets and the public debt 
market.  The Company raised approximately $433.9 million through the 
issuance of Common Shares and $120.8 million through the issuance of 
preferred shares of beneficial interest.  In addition, over the course 
of the year, the Company issued $350.0 million of investment grade rated 
unsecured notes with maturities ranging from six to 10 years.  The 
Company expects to continue to strengthen its capital structure.

IMPACT OF YEAR 2000

The Year 2000 issue continues to receive a significant amount of 
publicity and attention.  The issue is the result of computer programs 
being written using two digits rather than four digits to define the 
applicable year.  If problematic and not corrected, many computer 
applications could fail or create erroneous results by or at the Year 
2000.  The Company's property management and accounting system uses four 
digit year fields.  The Company has been reviewing and will continue to 
review its building operating systems on a building by building basis in 
conjunction with its annual maintenance program.  The Company, based on 
the present status of its systems and the results of the reviews 
completed to date, believes any amount required to remediate any Year 

     25

2000 issues will not be material to the Company's business, operations 
or financial conditions.

FORWARD-LOOKING STATEMENTS

When used throughout this report, the words "believes," "anticipates," 
and "expects" and similar expressions are intended to identify forward-
looking statements.  Such statements indicate that assumptions have been 
used that are subject to a number of risks and uncertainties which could 
cause actual financial results or management plans and objectives to 
differ materially from those projected or expressed herein, including:  
the effect of national and regional economic conditions; the Company's 
ability to identify and secure additional properties and sites that meet 
its criteria for acquisition or development; the acceptance of the 
Company's financing plans by the capital markets; and the effect of 
prevailing market interest rates and the pricing of the Company's shares 
of beneficial interest; 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 
publicly release the results of any revisions to these forward-looking 
statements that may be made to reflect any future events or 
circumstances.

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, 1997 with the results of 
operations of the Company for the year ended December 31, 1996, and the 
results of operations of the Company for the year ended December 31, 
1996 with the results of operations of the Company for the year ended 
December 31, 1995. As a result of the differing levels of acquisitions 
by the Company in 1997 and 1996, the overall operating results of the 
Company during such periods are not directly comparable.  However, 
certain data, including the "Same Store" comparison, does lend itself to 
direct comparison.  As used herein, the term "Company" includes the 
Trust, the Operating Partnership and their subsidiaries. 
 
RESULTS OF OPERATIONS
 
COMPARISON OF YEAR ENDED DECEMBER 31, 1997 TO YEAR ENDED DECEMBER 31, 
1996.

Rental revenues increased from $154.3 million for the year ended 
December 31, 1996 to $232.5 million for the year ended December 31, 
1997.  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 eight 
properties for $35.4 million. 

Operating expense reimbursement increased from $35.9 million for the 
year ended December 31, 1996 to $55.5 million for the year ended 
December 31, 1997.  This increase is a result of the reimbursement from 
tenants for increases in rental property expenses and real estate taxes.  
The operating expense recovery percentage (the ratio of operating 
expense reimbursement to rental property expenses and real estate taxes) 

      26

increased from 87.8% for the year ended December 31, 1996 to 90.9% for 
the year ended December 31, 1997.
 
Rental property and real estate tax expenses increased from $40.9 
million for the year ended December 31, 1996 to $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, 1996) increased from $94.1     
million for the year ended December 31, 1996 to $98.8 million for the 
year ended December 31, 1997.  This increase of 5.01% is due to 
increases in rental rates and increases in occupancy. 
 
Set forth below is a schedule comparing the operating results for the  
Same Store properties for the years ended December 31, 1997 and 1996.

                                         ========       ======== 
 
General and administrative expenses increased from $8.0 million for the 
year ended December 31, 1996 to $10.7 million for the year ended 
December 31, 1997.  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 from $28.2 million for 
the year ended December 31, 1996 to $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 from $38.5 million for the year ended  
December 31, 1996 to $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 $576.3 million in 1996 and $819.4 in 
1997.  This increase is partly offset by the lower interest rate 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 Rating Group ("S&P") and Moody's Investment Service, 
Inc. ("Moody") 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  
from $77.2 million for the year ended December 31, 1996 to $120.0 
million for the year ended December 31, 1997.  In addition, income 

     27

before minority interest increased from $37.6 million for the year ended 
December 31, 1996 to $66.1 million for the year ended December 31, 1997. 
 
COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31,  
1995.  

Rental revenues increased from $117.0 million for the year ended 
December 31, 1995 to $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, 1995, 
the Company owned 151 properties and, through December 31, 1995, 
acquired 52 additional properties (net of two properties exchanged in 
connection with such acquisitions) and completed development of five  
properties for a Total Investment of $223.1 million.  As of January 1, 
1996, the Company owned 208 properties, and, through December 31, 1996, 
acquired 33 additional properties and completed the development on 19 
properties for a Total Investment of $232.2 million. 

Operating expense reimbursement increased from $24.6 million for the 
year ended December 31, 1995 to $35.9 million for the year ended 
December 31, 1996.  This increase is a result of the reimbursement from 
tenants for increases in rental property expenses and real estate taxes.  
The operating expense recovery percentage (the ratio of operating 
expense reimbursement to rental property expenses and real estate taxes) 
increased from 83.9% for the year ended December 31, 1995 to 87.8% for 
the year ended December 31, 1996.
 
Rental property and real estate tax expenses increased from $29.3 
million for the year ended December 31, 1995 to $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, 1995) increased from $68.0     
million for the year ended December 31, 1995 to $71.5 million for the 
year ended December 31, 1996.  This increase of 5.1% is due to increases 
in rental rates and increases in occupancy.

General and administrative expenses increased from $5.2 million for the 
year ended December 31, 1995 to $8.0 million for the year ended December 
31, 1996.  This $2.8 million increase is due to the increase in 
personnel and other related overhead costs necessitated by the increase 

       28

in the number of properties owned during the respective periods.  
Included in the general and administrative expenses for the year ended 
December 31, 1996 is a $704,000 non-cash charge resulting from the 
amortization of a stock award over its vesting period.  There is no 
corresponding charge for the year ended December 31, 1995.
 
Depreciation and amortization expenses increased from $22.5 million in 
1995 to $28.2 million in 1996.  This increase is due to the increase in 
the number of properties owned during the respective periods. 

Interest expense increased from $37.7 million for the year ended  
December 31, 1995 to $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 $397.4 million in 1995 and $576.3 
million 1996.  This increase is partly offset by the lower interest rate 
on the outstanding debt because of the 1% reduction in interest rate on 
the Line of Credit borrowings which became effective on May 1, 1995, and 
because of a decrease in the outstanding Convertible Debentures due to 
the conversion of $58.7 million principal amount of Convertible 
Debentures in 1996.
 
As a result of the foregoing, the Company's operating income increased  
from $60.0 million for the year ended December 31, 1995 to $77.2 million 
for the year ended December 31, 1996.  In addition, income before 
minority interest increased from $22.3 million for the year ended 
December 31, 1995 to $37.6 million for the year ended December 31, 1996. 

LIQUIDITY AND CAPITAL RESOURCES 
 
As of December 31, 1997, the Company had cash and cash equivalents of  
$55.1 million.
 
Net cash flow provided by operating activities increased from $64.4 
million for the year ended December 31, 1996 to $126.9 million for the 
year ended December 31, 1997.  This $62.5 million increase was primarily 
due to the additional cash flow generated by the greater number of 
properties in service during the latter period. 

Net cash used in investing activities increased from $265.4 million for 
the year ended December 31, 1996 to $854.9 million for the year ended 
December 31, 1997.  This $589.5 million increase was a result of the  
increase in investment in acquisitions and development from $232.2 for 
the year ended December 31, 1996 to $871.5 million for the year ended 
December 31, 1997. 

Net cash provided by financing activities increased from $210.0 million 
for the year ended December 31, 1996 to $763.5 million for the year 
ended December 31, 1997. This increase was primarily attributable to the 
Follow-On Offering (as defined below), and the exercise of the related 
overallotment option, which were completed on March 24, 1997 and April 
1, 1997, respectively, which resulted in the issuance of an aggregate of 
8,250,000 Common Shares, the Preferred Offering (as defined below), 
which was completed on August 11, 1997, which resulted in the issuance 
of 5,000,000 preferred shares of beneficial interest, the Senior Notes 
Offering (as defined below), which was completed on August 19, 1997, 
which resulted in the issuance of $200 million principal amount of 
unsecured notes, the Common Shares Offering (as defined below), which 
was completed on November 19, 1997, which resulted in the issuance an 
aggregate of 9,200,000 Common Shares, the Direct Placement (as defined 
below), which was completed on December 11, 1997, which resulted in the 
issuance of 796,505 Common Shares and the issuance of $150 million 

      29

principal amount of unsecured notes in December. The net proceeds to the 
Company of these offerings were approximately $191.7 million, $120.8 
million, $198.0 million, $222.2 million, $20.0 million and $149.0 
million, respectively.

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

The Company funded its long-term liquidity requirements, such as 
property acquisition and development activities, primarily through 
secured line of credit facilities (the "Lines of Credit").  During the 
second quarter of 1997, the Company replaced these secured facilities 
with a $325.0 million unsecured line of credit (the "Credit Facility").

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 the Eurodollar Rate.

Periodically, the Company pays down borrowings on the Credit Facility 
with funds from long term capital sources.  In the year ended December 
31, 1997, the Company used approximately $907.7 million of the proceeds 
from the Follow-On Offering, Common Shares Offering, the Preferred 
Offerings, the Senior Notes Offering, the Direct Placement and unsecured 
note issuances to paydown the Credit Facility.
 
As of December 31, 1997, $363.6 million in mortgage loans were 
outstanding with maturities ranging from 1998 to 2013. The interest 
rates on $344.4 million of mortgage loans are fixed and range from 6% to 
9.13%.  Interest rates on $19.2 million of mortgage loans float with 
LIBOR or prime, all of which are subject to certain caps.  The weighted 
average interest rate for the mortgage loans is 7.7%, and the weighted 
average remaining term is 8.3 years.
 
GENERAL 
 
The Company expects to incur variable rate debt, including borrowings 
under the Credit Facility, from time to time. The Company believes that 
its existing sources of capital, including public debt and equity 
markets, will provide sufficient funds to finance its continued 
acquisition and development activities.  In this regard, the Company 
continues to evaluate its long-term capital sources which generally 
include the availability of debt financing and access to equity.  

In July 1995, the Company filed a shelf registration with the Securities 
and Exchange Commission that enabled the Company to offer up to an 
aggregate of $350.0 million of securities, including common shares of 
beneficial interest, preferred shares of beneficial interest and debt 
(the "Initial Shelf Registration"). On November 27, 1995, the Company 
completed a follow-on public offering of 7,200,000 common shares

and debt (the "Third Shelf Registration").  The Third Shelf Registration 
Statement became effective on January 4, 1998.  Collectively, the 
Initial Shelf Registration, the Second Shelf Registration and the Third 
Shelf Registration are referred to as the "Shelf Registration 
Statement".

In connection with the acquisition of properties during the year ended 
December 31, 1997, the Company issued 1,197,739 Units.

Subsequent to year end, on January 12, 1998, the Company augmented its

the program, on January 23, 1998, the Company sold $100 million

available under the medium-term note program).

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 
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.

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 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 

      32

income as an indicator of the Company's operating performance or to cash 
flows as a measure of liquidity.  Funds from Operations also does not 
represent cash flows generated from operating, investing or financing 
activities as defined by GAAP.  Funds from Operations for the years 
ended December 31, 1997, 1996 and 1995 are as follows:

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 bears interest at a variable rate; 
therefore, the amount of interest payable under the Credit Facility will 
be influenced by changes in short-term interest rates, which tend to be 
sensitive to inflation.  To the extent an increase in inflation would 
result in increased operating costs, such as in insurance, real estate 
taxes 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.

The dual presentation of financial statements for 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, 1997 and 1996, and the 
related consolidated statements of operations, shareholders' equity, and 
cash flows for each of the three years in the period ended December 31, 
1997.  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 financial statements referred to above present  
fairly, in all material respects, the consolidated financial position of  
Liberty Property Trust at December 31, 1997 and 1996, the consolidated  
results of Liberty Property Trust's operations and cash flows for each  
of the three years in the period ended December 31, 1997 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, the "Company").  At December 31, 1997, the 
Trust owned a 91.84% interest in the Operating Partnership as the sole 
general partner and a 0.02% interest as a limited partner. 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 Mid-Western 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 direct and indirect subsidiaries including Liberty  
Property Development Corporation. 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 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.
 
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.   

     40

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 
 
In the fourth quarter of 1997, the Company adopted Statement of 
Financial Accounting Standards No. 128, "Earnings per Share", which 
replaced the calculation of primary and fully diluted income per common 
share with basic and diluted income per common share.  Unlike primary 
income per common share, basic income per common share excludes any 
dilutive effects of options.  Diluted income per common share includes 
the weighted average common shares and dilutive effect of the 
outstanding options for the years ended December 31, 1997, 1996 and 
1995, 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.  All income per common share amounts for all 
periods have been presented, and where appropriate, restated to conform 
to the Statement 128 requirement.

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

Basic income per common share would be $1.39 calculated as if the 
debenture conversions which occurred in 1997 had occurred on January 1, 
1997.  

Income Taxes 
 
The Trust qualifies and intends to continue to qualify as REIT under the 
Internal Revenue Code.  As a REIT, the Trust generally will not be 
subject to federal income tax to the extent that it distributes at least 
95% of its REIT taxable income to its shareholders.  The Trust may be 
subject to certain state and local taxes on its income and property and 
to federal income and excise taxes on its undistributed income.

On a per share basis, the Company paid common dividends of $1.65, $1.61, 
and $1.60 during the years ended December 31, 1997, 1996 and 1995.  The 
portions of the 1997 common dividend relating to return of capital, 
earnings and profits, and capital gain are 30.4%, 68.4%, and 1.2%, 
respectively.  The capital gain distribution for the 1997 common

(25% tax rate) and long-term capital gain (20% tax rate) are 63.4% and 
36.6%, respectively.
 
The Federal tax cost basis of the real estate at December 31, 1997 was

       42

Depreciation expense was $36.0 million in 1997, $25.0 million in 1996, 
and $19.7 million in 1995. 
 
As of December 31, 1997, the Company has commenced development on 43 
properties, which upon completion are expected to comprise approximately 
4.1 million square feet of leaseable space.  As of December 31, 1997, 
approximately $156.1 million has been expended for the development of 
these projects and an additional $148.8 million is required for 
completion. 
 
4.   RELATED PARTY TRANSACTIONS 
 
An affiliated company provides construction services to the Company.   
Amounts paid to this affiliate were $8.2 million in 1997, $29.7 million 
in 1996 and $6.2 million in 1995. 
 
During 1995, three properties were purchased from partnerships in which 
officers of the Company had an interest.  The officers received no 
financial consideration for the purchase. 
 
Pursuant to agreements, the Company has been retained by an affiliate  
(Rouse Kent Limited) to provide development, management and other  
services. For the years ended December 31, 1997, 1996 and 1995  
the fees for these services were $600,000 per year.  Additionally, the 
Company committed to loans in 1996 to two affiliates (Rouse Kent 
Development Limited and 1 Tower View Limited) for development projects.  
As of December 31, 1997, only one (1 Tower View Limited) of these loans, 
with a balance of $5.5 million, remained outstanding.  As of December 
31, 1996, the balance of these loans was $7.4 million.
 
5.   MORTGAGE LOANS, UNSECURED NOTES, LINES OF CREDIT AND CONVERTIBLE 
DEBENTURES
 
Long term indebtedness consists generally of mortgage loans,  
unsecured notes, lines of credits, and convertible debentures.  
The average annualized interest rates for the years 
ended December 31, 1997, 1996 and 1995, were approximately 7.5%, 7.6% 
and 7.8%, respectively.  Interest expense for the years ended December 
31, 1997, 1996 and 1995, aggregated $53.9 million, $38.5 million and 
$37.7 million, respectively.  Interest costs during these periods of 
$11.8 million, $7.7 million and $3.5 million, were capitalized.  Cash 
paid for interest for the years ended December 31, 1997, 1996 and 1995, 
was $54.9 million, $43.7 million and $36.7 million, respectively. 

Mortgage loans with maturities ranging from 1998 to 2013 are  
collateralized by and in some instances cross-collateralized by  
properties with a book value of $493.2 million.  The interest rates on 
$344.4 million of mortgage loans are fixed and range from 6% to 9.13%.  
Interest rates on $19.2 million of mortgage loans float with Eurodollar 
or prime and are subject to certain caps.  The weighted average interest 
rate on the mortgage loans is 7.7% and the weighted average remaining 
term is 8.3 years. 

     43

The aggregate maturities of the mortgage loans outstanding are as  
follows (in thousands):  
 
        1998                 $ 13,443 
        1999                   21,718 
        2000                   32,451  
        2001                   22,700
        2002                    6,044
        Thereafter            267,235 
                             -------- 
        TOTAL                $363,591 
                             ======== 

The unsecured notes are comprised of $350 million principal amount of 
fixed rate unsecured notes with four maturities, which are as follows:  
$50 million principal amount bears interest at 6.97% and is due 2003, 
$100 million principal amount bears interest at 7.1% and is due 2004, 
$100 million principal amount bears interest at 6.95% and is due 2006, 
and $100 million principal amount bears interest at 7.25% and is due 
2007.
 
The line of credit 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 Eurodollar Rate (7.09% at December 31, 1997).  The rate for both 
Lines of Credit at December 31, 1996 was 7.13%.  Customary fees apply to 
the Credit Facility including an annual administrative fee and an unused 
line fee. 

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% and increases with increases in the dividend payment on the 
Company's Common Shares.  At the current $.42 per share per quarter 
dividend payment rate, the effective interest rate on the convertible 
debentures is 8.4%.  At December 31, 1996, the effective interest rate 
on the convertible debentures was 8.2%.  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. During the year ended December 31, 1997, $2.4 million of 
deferred financing costs relating to converted convertible debentures 
were charged to additional paid-in capital.  During the year ended 
December 31, 1996, the Company paid sums aggregating $1.0 million to 
facilitate the conversion of $58.7 million of convertible debentures 
into 2,934,300 Common Shares.  During the year ended December 31, 1996, 
$2.9 million of related deferred financing costs were charged to 
additional paid-in capital.  At December 31, 1997 and 1996 the 
convertible debentures were convertible into 5,577,150 Common Shares and 
8,560,700 Common Shares, respectively.  

     44

The fair value of the convertible debentures at December 31, 1997 was 
$159.3 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, 1997, for similar types of 
borrowing arrangements.  The carrying values of the mortgages, the 
unsecured notes and the Credit Facility approximate their fair values. 
 
6. LEASING ACTIVITY 
 
Future minimum rental payments due from tenants under non-cancellable  
operating leases as of December 31, 1997 are as follows (in thousands): 
 
        1998                 $  211,211
        1999                    186,375
        2000                    147,201
        2001                    109,323
        2002                     85,078
        Thereafter              309,527
                             ---------- 
        TOTAL                $1,048,715 
                             ========== 
 
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.  MINORITY INTEREST 
 
In conjunction with the formation of the Company and certain subsequent 
acquisitions, persons contributing interest in properties to the 
Operating Partnership have received limited partnership interests in the 
Operating Partnership.  In connection with the acquisition of properties 
for the year ended 1997, the Company issued 1,197,739 units.  There were 
no units issued in connection with the acquisition of properties in 
1996.  The aggregate outstanding limited partnership interests have the 
same economic characteristics as would 4,668,700 Common Shares 
outstanding as of December 31, 1997, 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. 
 
Minority interest in the accompanying consolidated financial statements  
relates to such limited partnership interests. 
  
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. 
 
     45

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 2,100,000 
shares of the Company's Common Shares.  An amendment to increase the 
number of Common Shares available for awards under the Share Incentive 
Plan from 2,100,000 to 4,033,535 was approved at the 1997 Annual 
Shareholders' Meeting.  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 1997, 1996 and 1995, 
respectively: risk-free interest rate of 5.5%, 6.2% and 6.2%;  
dividend yield of 6.0%, 7.0% and 7.0%; volatility factor of the expected 
market price of the  Common Shares of .155, .164 and .164; and a 
weighted-average expected life of the option of 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):

on reported net income for future years because of the staggered vesting  
periods of the options.

Exercise prices for options outstanding as of December 31, 1997 ranged

of those options is 7.7 years.  
 
An additional 1,858,502, 511,887, and 632,400 Common Shares were 
reserved for issuance for future grants from the Share Incentive Plan at 
December 31, 1997, 1996 and 1995, respectively. 

9.  SHAREHOLDER'S 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 
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.

10.   COMMITMENTS AND CONTINGENCIES 
 
All of the Properties 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 

     47

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 800 acres of land for commercial development.  The 
purchase price of the land is $17.5 million, plus accrued interest at 
7.5% per annum, payable over 10 years ending in 2007.

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.

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, 1997, and 1996 , and the related consolidated statements of 
operations, owners' equity, and cash flows for each of the three years 
in the period ended December 31, 1997.  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 financial statements referred to above present  
fairly, in all material respects, the consolidated financial position of  
Liberty Property Limited Partnership at December 31, 1997 and 1996, the 
consolidated results of Liberty Property Limited Partnership's  
operations and cash flows for each of the three years in the period 
ended December 31, 1997, 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, the "Company").  At December 31, 1997, the 
Trust owned a 91.84% interest in the Operating Partnership as the sole 
general partner and a 0.02% interest as a limited partner. 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 Mid-Western 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  
direct and indirect subsidiaries including Liberty Property Development  
Corporation. 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 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.
 
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.  
 
      74

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. 
 
3.   REAL ESTATE 
 
At December 31, 1997 and 1996, the Company owned and operated industrial

As of December 31, 1997 the Company has commenced development on 43 
properties, which upon completion are expected to comprise approximately 
4.1 million square feet of leaseable space.  As of December 31, 1997 
approximately $156.1 million has been expended for the development of these 
projects and an additional $148.8 million is required for completion. 
 
4.   RELATED PARTY TRANSACTIONS 
 
An affiliated company provides construction services to the  Company.   

       75

Amounts paid to this affiliate were $8.2 million in 1997, $29.7 million 
in 1996 and $6.2 million in 1995.  

During 1995, three properties were purchased from partnerships in which 
officers of the Company had an interest.  The officers received no 
financial consideration for the purchase. 
 
Pursuant to agreements, the Company has been retained by an affiliate  
(Rouse Kent Limited) to provide development, management and other  
services. For the years ended December 31, 1997, 1996 and  1995, the 
fees for these services were $600,000 per year.   Additionally, the 
Company committed to loans in 1996 to two affiliates (Rouse Kent 
Development Limited and 1 Tower View Limited) for development projects.  
At December 31, 1997, only one (1 Tower View Limited) of these loans, 
with a balance of $5.5 million, remained outstanding.  As of December 
31, 1996, the balance of these loans was $7.4 million.
 
5.   MORTGAGE LOANS, UNSECURED NOTES, LINES OF CREDIT, AND CONVERTIBLE 
DEBENTURES
 
Long term indebtedness consists generally of mortgage loans,  
unsecured notes, lines of credit and convertible debentures. 
The average annualized interest rates for the years ended 
December 31, 1997, 1996 and 1995,  were approximately 7.5%, 7.6% and 
7.8%, respectively.  Interest expense for the years ended December 31, 
1997, 1996 and 1995,  aggregated $53.9 million, $38.5 million and $37.7 
million, respectively.  Interest costs during these periods of $11.8 
million, $7.7 million and $3.5 million were capitalized.  Cash paid for 
interest for the years ended December 31, 1997, 1996 and 1995, was $54.9 
million, $43.7 million $36.7 million, respectively. 
 
Mortgage loans with maturities ranging from 1998 to 2013 are 
collateralized by and in some instances cross-collateralized by  
properties with a book value of $493.2 million.  The interest rates on 
$344.4 million of mortgage loans are fixed and range from 6% to 9.13%.  
Interest rates on $19.2 million of mortgage loans float with Eurodollar 
or prime and are subject to certain caps.  The weighted average interest 
rate on the mortgage loans is 7.7% and the weighted average remaining 
term is 8.3 years. 
 
The aggregate maturities of the mortgage loans outstanding are as  
follows (in thousands): 
 
        1998                 $ 13,443  
        1999                   21,718 
        2000                   32,451  
        2001                   22,700
        2002                    6,044
        Thereafter            267,235 
                             -------- 
        TOTAL                $363,591 
                             ======== 
 
The unsecured notes are comprised of $350 million principal amount of 
fixed rate unsecured notes with four maturities which are as follows:  
$50 million principal amount bears interest at 6.97% and is due 2003, 
$100 million principal amount bears interest at 7.1% and is due 2004, 
$100 million principal amount bears interest at 6.95% and is due 2006, 
and $100 million principal amount bears interest at 7.25% and is due 
2007.

       76

The line of credit 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 Services, 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 Eurodollar Rate (7.09% at December 31, 1997).  The rate for
both lines of credit at December 31, 1996 was 7.13%.  Customary fees 
apply to the Credit Facility including an annual administrative fee and 
an unused line fee.

The convertible debentures are due on June 23, 2001 and are 
exchangeable for the 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% and increases with increases in the dividend payment on the 
Company's Common Shares.  At the current $.42 per share per quarter 
dividend payment rate, the effective interest rate on the convertible 
debentures is 8.4%.  At December 31, 1996 the effective interest rate on 
the convertible debentures was 8.2%.  During the year ended December 31, 
1997, the Company paid sums aggregating $98,000 to facilitate the 
conversion of $17.3 million of debentures into 862,650 Common Shares.  
During the year ended December 31, 1997, $2.4 million of deferred 
financing costs relating to converted debentures were charged to 
additional paid-in capital.  During the year ended December 31, 1996, 
the Company paid sums aggregating $1.0 million to facilitate the 
conversion of $58.7 million of convertible debentures into 2,934,300 
Common Shares.  During the year ended December 31, 1996, $2.9 million of 
related deferred financing costs were charged to additional paid-in 
capital.  At December 31, 1997 and 1996 the convertible debentures were 
convertible into 5,577,150 Common Shares and 8,560,700 Common Shares, 
respectively.

The fair value of the convertible debentures at December 31, 1997 was 
$159.3 million based on the closing bid price of the Common Shares on 
the New York Stock Exchange.  The fair values of the mortgages, 
unsecured notes and Credit Facility were estimated using discounted cash 
flow analysis, based on the Company's estimated incremental borrowing 
rate at December 31, 1997, for similar types of borrowing arrangements.  
The carrying values of the mortgages, unsecured notes and the Credit 
Facility approximate their fair values. 
 
6.   LEASING ACTIVITY 
 
Future minimum rental payments due from tenants under non-cancellable  
operating leases as of December 31, 1997 are as follows (in thousands): 

        1998                 $  211,211   
        1999                    186,375
        2000                    147,201
        2001                    109,323
        2002                     85,078 
        Thereafter              309,527
                             ---------- 
        TOTAL                $1,048,715 
                             ========== 
 
     77

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.   COMMITMENTS AND CONTINGENCIES 
 
All of the Properties 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, 
approximately 800 acres of land for commercial development.  The 
purchase price of the land is $17.5 million, plus accrued interest at 
7.5% per annum, payable over 10 years ending in 2007.

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.
