PART I 
 
ITEM 1. BUSINESS 
 
THE COMPANY 
 
Liberty Property Trust (the "Trust") is one of the largest owners and  
operators of suburban industrial and office real estate in the United  
States.  The Trust is a self-administered and self-managed Maryland real  
estate investment trust (a "REIT").  The Trust and its subsidiary,  
Liberty Property Limited Partnership, a Pennsylvania limited partnership  
(the "Operating Partnership") and, together with the Trust, the  
"Company"), were 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 and Mid-Atlantic United  
States.  Substantially all of the Trust's assets are owned directly or  
indirectly by, and substantially all of the Trust's operations are  
conducted directly or indirectly by, the Operating Partnership. 
 
The Company provides leasing, property management, acquisition,  
development, construction management, design management and other  
related services for a portfolio which, as of December 31, 1996,  
consisted of 259 industrial and office properties (the "Properties in  
Operation") totaling approximately 20.6 million leasable square feet.   
As of December 31, 1996, the Company also had 22 properties under  
development (the "Properties Under Development") and, together with the  
Properties in Operation, the "Properties").   The Properties Under  
Development are expected to generate approximately 3.0 million leasable  
square feet.  The land, which is all zoned for commercial use, is  
believed to be capable of supporting, as and when developed, 9.3 million  
leaseable square feet. The Properties are located principally within the  
Southeastern and Mid-Atlantic United States.  As of December 31, 1996,  
the Properties in Operation were approximately 92.8% leased to over 800  
tenants. 
 
During the year ended December 31, 1996, through Total Investments (as  
defined below) aggregating $232.2 million, the Company has increased its  
total leasable square footage of industrial and office space by  
approximately 23.5% by acquiring 33 properties totaling approximately  
2.4 million leasable square feet and by developing 19 properties  
totaling approximately 1.5 million leasable 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.  During 1996, the Company has also increased its holdings  
of land for future development by 98 acres (net of acreage utilized in  
1996 for development projects and sold), all zoned for commercial use. 

                                 -5- 
<PAGE>

As of December 31, 1996, the Properties in Operation consisted of 173  
industrial and 86 office properties.  The Company's industrial  
properties are located principally in suburban mixed-use developments or  
business parks and include warehouse/distribution facilities, as well as  
flex facilities which accommodate both industrial and office use. The  
industrial activities in the Company's flex facilities typically include  
service, assembly, light manufacturing and research and development.   
The Company's office properties are mid-rise and single story office  
buildings, located principally in suburban mixed-use developments or  
office parks. 
 
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 90.05% at December 31, 1996.  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 Common Shares of Beneficial Interest $.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,  
principally senior executives of the Trust and their affiliates.  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 3.5 million Common Shares on December 31,  
1996. 
 
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 primary markets. 
 
MANAGEMENT AND EMPLOYEES 
 
The Company's 199 employees (as of February 18, 1997) are under the  
direction of 17 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 14 years. The Company's in-house leasing, marketing  
and property management staff operates in 8 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 primary objective is to increase funds from operations.   
See Item 6, "Selected Financial Data", for the definition of this term.   
The operating strategies for achieving this goal are to deliver  
outstanding tenant service, emphasize marketing to attract new tenants  
and enhance the Company's portfolio through the acquisition and  
development of high quality properties in markets affording  
opportunities for attractive investments.  In pursuing these strategies,  

                                -6-
<PAGE>

the Company seeks to manage its capital structure to fund growth while  
maintaining financial liquidity and stability. 
 
INTERNAL GROWTH STRATEGIES 
 
Management believes that the Properties offer significant opportunities  
for the Company to increase its rental revenues and cash flow.  The  
Company seeks to increase 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 1990s, 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. As these leases expire, the Company  
expects, although no assurance can be given, that replacement leases  
will reflect higher rental rates as economic conditions continue to  
improve and the oversupply of commercial real estate is mitigated by the  
decreased commercial construction starts in recent years. 
 
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, 1996 provide for contractual  
rental increases that are expected to contribute an additional $1.2   
million to the Company's cash flow for the year ending December 31,  
1997.  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 59.0% for the year  
ended December 31, 1996. 
 
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 parties.  For example, the Company relies  
primarily on its locally based leasing and marketing staff, thereby  
reducing commissions to third parties.  Similarly, 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  

                             -7-

<PAGE>

and preventive maintenance program designed to reduce the operating  
costs of the Properties and maintain their long-term value. 
 
ACQUISITIONS 
 
STRATEGY.  The Company seeks to acquire properties consistent with its  
business objectives and strategies for growth.  The Company has  
identified the following categories of acquisitions: 
 
SINGLE-ASSET ACQUISITIONS: 
 
STABILIZED ACQUISITIONS:  Stabilized Acquisitions consist of individual  
properties generally located within the Company's existing markets,  
which are typically at high occupancy levels upon acquisition. During  
the year ended December 31, 1996, the Company acquired 27 properties  
which can be characterized as Stabilized Acquisitions containing  
approximately 1.6 million leasable square feet of industrial and office  
space for a Total Investment of approximately $96.3 million.  These  
properties were 96.7% leased as of December 31, 1996. 
 
ENTREPRENEURIAL ACQUISITIONS:  Entrepreneurial Acquisitions consist of  
individual properties generally located within the Company's existing  
markets, 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 return when fully leased.   
During the year ended December 31, 1996, the Company acquired 6  
properties which can be characterized as Entrepreneurial Acquisitions  
containing approximately 783,000 leasable square feet of industrial and  
office space which was either vacant or partially leased at the time of  
acquisition,  for a Total Investment of approximately $36.6 million.   
Approximately 45,000 square feet of space was acquired vacant for a  
Total Investment of approximately $1.5 million, and was 100.0% leased as  
of December 31, 1996.  The remaining 738,000 square feet of this space  
was acquired partially leased for a Total Investment of approximately  
$35.1 million and was 68.1% leased as of December 31, 1996.  
 
PORTFOLIO ACQUISITIONS:   
 
Groups of properties or existing real estate companies that in either  
case offer an immediate return which can be enhanced by the Company's  
management expertise and financial strength. 
 
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  
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 in high-occupancy  
markets in which the Company has identified sufficient demand at market  
rental rates justifying such construction. 
 
                             -8-

<PAGE> 

COMPLETED DEVELOPMENTS: During the year ended December 31, 1996, the  
Company completed 4 build-to-suit and 15 inventory  
projects, approximately 1.5 million square feet of leasable space  
representing a Total Investment of approximately $99.3 million.  As of  
December 31, 1996, the completed development properties were 91.7%  
leased. 
 
PROPERTIES UNDER DEVELOPMENT: As of December 31, 1996,  the Company  was  
developing 22 development properties which, upon completion, are  
expected to generate approximately 3.0 million square feet of leasable  
space representing a Total Investment of approximately $153.8 million.   
Approximately 68.8% of such leaseable space was pre-leased as of  
December 31, 1996. Five of these properties are 100% pre-leased under net  
leases as build-to-suit projects. There can be no assurance that any of  
these Properties Under Development will be completed, or that the  
Company's budgets or estimates of construction costs or time periods  
necessary to complete construction, will be realized.  The Company  
expects to complete development of 12 properties (totalling 2.2 million  
square feet of leasable space) in the year ended December 31, 1997. 
 
LAND:  As of December 31, 1995, the Company owned 914 acres of land for  
development, all zoned for commercial use. During the year ended  
December 31, 1996 the Company purchased an additional 315 acres of land  
for development, and utilized 177 acres in development projects and sold  
40 acres.  Substantially all of the remaining 1,012 acres is located  
adjacent to or within existing industrial or business parks with site  
improvements, such as public sewers, water and utilities, available for  
service and the Company anticipates that the land would support 9.3  
million leasable square feet.  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, particularly as the  
availability of land within the Company's geographic markets continues  
to diminish. 
 
INTERNATIONAL OPERATION:  The Company earns an annual fee of $600,000  
(subject to adjustment for additional services undertaken by the  
Company) for its management services provided 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 for nominal  
consideration and an option to purchase future buildings and land within  
the park.  The Company's international operations also include 4  
Properties in Operation in the County of Kent. 
 
SUBSEQUENT ACTIVITIES 
 
Since December 31, 1996, the date as of which tabular data presented  
herein is reflected, the Company has purchased three office buildings  
containing approximately 267,134 leasable square feet for a Total  
Investment of $26.6 million. In addition, the Company has completed  

                             -9-

<PAGE>

development on three industrial distribution properties containing  
approximately 1.4 million leasable square feet for a Total Investment of  
$42.1 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 build-to-suit projects  
totalling over $200.0 million. 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 property and on the rents  
charged at the Properties in Operation.  However, the Company believes  
that its capital base, its existing sources of credit and its access as  
a public entity to the capital markets to raise funds during periods  
when conventional sources of financing may be unavailable or  
prohibitively expensive will provide the Company with competitive  
advantages.  Further, the Company believes that the number of real  
estate developers has decreased as a result of the recessionary market  
conditions and tight credit markets during the early 1990s as well as  
the reluctance on the part of more conventional financing sources to  
fund development and acquisition projects.  Moreover, the Company  
believes that its responsiveness to tenant needs will enable it to  
attract and maintain 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  

                                -10-

<PAGE>

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 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 on  
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  
ordinary 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 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"), as former owners.  The Company acquired the Church  
Road Properties from the Predecessor upon formation.  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 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, Mr. Congdon, Mr. Hammers and Joseph  
P. Denny, have agreed to indemnify the Company for a period of ten years  
commencing in June 1994 with respect to material environmental  
liabilities associated with the Church Road Properties.

                                -20-
<PAGE>

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>  Industry analysts generally consider funds from operations to be  
an appropriate measure of the performance of an equity REIT.  Funds from  
operations is defined as net income or loss (computed in accordance with  
generally accepted accounting principles), excluding gains (or losses)  
from debt restructuring and sales of property, plus real estate related  
depreciation and amortization excluding the amortization of deferred  
financing costs and depreciation of non-real estate assets.  Funds from  
operations does not represent cash generated from operating activities  
in accordance with generally accepted accounting principals and is not  
necessarily indicative of cash available to fund cash needs.  The  
Company believes that to facilitate a clear understanding of the  
Company's operating results, funds from operations should be examined in  
conjunction with net income, although it should not be considered as an  
alternative to net income as an indicator of the Company's operating  
performance or as an alternative to cash flow as a measure of liquidity.   
Funds from operations computed by the Company may not be comparable to  
other similarly titled measures of other REITs. 
 
ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND  
RESULTS OF OPERATIONS 
 
OVERVIEW 
 
The following discussion is based on the consolidated financial  
statements of the Company and the combined financial statements of the  
Predecessor.  The combined financial statements of the Predecessor  
reflect the combination of data from the balance sheets and the  
statements of operations of the partnerships that owned the properties,  
and the management, development and leasing operations of the  
Predecessor that were contributed to the Company in connection with its  
formation, which was consummated concurrently with its initial public  
offering.  The combined financial statements of the Predecessor are  
presented for comparative purposes only. 
 
The following discussion compares 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, and the  
results of operations of the Company for the year ended December 31,  
1995 with the results of operations of the Company and Predecessor, on a  
combined basis, for the year ended December 31, 1994.  As used herein,  
the term "Company" includes the Trust, the Operating Partnership and  
their subsidiaries (and, where the context indicates, the Predecessor). 
 
RESULTS OF OPERATIONS 
 
Comparison of year ended December 31, 1996 to year ended December 31,  
1995.  Total revenues (principally rental revenues and operating expense  
reimbursement) 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  

                             -23-
<PAGE>

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. 
 
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, and because of significant snow removal  
and other seasonal operating costs incurred as a result of the severe  
1996 winter. 
 
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. 
 
Set forth below is a schedule comparing the operating results for the  
Same Store properties for the years ended December 31, 1996 and 1995.

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  
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. 

                               -24-

<PAGE> 
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 in 1996.  This increase is partly offset by the lower  
interest rate on the outstanding debt because of the 1% reduction in the  
interest rate on the Line of Credit borrowings which became effective on  
May 1, 1995, and because of a decrease in the outstanding Subordinated  
Debentures due to the conversion of $58.7 million 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. 
 
Comparison of year ended December 31, 1995 to year ended December 31,  
1994.  Total revenues (principally rental revenues and operating expense  
reimbursement) increased from $83.0 million for the year ended December  
31, 1994 to $117.0 million for the year ended December 31, 1995.  This  
increase was primarily due to the increase in the number of properties   
owned during the respective periods. From January 1, 1994 through June  
22, 1994, the Predecessor owned 113 properties.  Concurrent with the  
initial public offering, the Company purchased 18 properties for a Total  
Investment of $57.0 million.  From the consummation of its initial  
public offering through December 31, 1994, the Company purchased 20  
additional properties for $79.5 million.  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 the development of five properties  
for a Total Investment of $223.1 million. 
 
Rental property and real estate tax expenses increased from $21.8  
million for the year ended December 31, 1994 to $29.3 million for the  
year ended December 31, 1995.  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, 1994) increased from $52.4 million  
for the year ended December 31, 1994 to $53.3 million for the year ended  
December 31, 1995.  This increase of 1.7% was attributable primarily to  
an increase in the occupancy in the industrial distribution and office  
properties. 
 
Set forth below is a schedule comparing the property level operating  
income for the Same Store properties for the years ended December 31,  
1995 and 1994.

General and administrative expenses increased from $4.7 million for the  
year ended December 31, 1994 to $5.2 million for the year ended December  
31, 1995.  This $500,000 increase is due to an increase in the number of  
properties owned during the respective periods and as a result of costs  
incurred to operate as a publicly owned company during the entire period  
of 1995.  The Predecessor did not incur similar costs from January 1,  
1994 through June 22, 1994. 
 
Depreciation and amortization expenses increased from $14.7 million for  
the year ended December 31, 1994 to $22.5 million for the year ended  
December 31, 1995.  This increase is due to the increase in the number  
of properties owned during the respective periods. 
 
Interest expense increased from $34.2 million for the year ended  
December 31, 1994 to $37.7 million for the year ended December 31, 1995.   
Interest expense for 1994 reflects, 1) interest on $525.0 million of  
mortgage loans for the Rouse Group, which loans were satisfied from the  
proceeds of the initial public offerings, and 2) interest on the  
Debentures for the period from issuance at June 23, 1994 through  
December 31, 1994.  Interest expense for 1995 reflects, 1) interest on  
the Line of Credit borrowings and mortgage loans incurred to fund  
property acquisitions and development, and 2) interest on the Debentures  
for the full 1995 year. 
 
During the year ended December 31, 1994, the Company recognized $55.8  
million in extraordinary income from the extinguishment of debt. There  
was no similar item in 1995. 
 
As a result of the foregoing, income before the effect of minority  
interest and extraordinary items increased from $7.6 million in 1994 to  
$22.3 million in 1995.  In addition, the Company's operating income  
increased from $41.8 million in 1994 to $60.0 million in 1995. 
 
LIQUIDITY AND CAPITAL RESOURCES 
 
As of December 31, 1996, the Company had cash and cash equivalents of  
$19.6 million.  Working capital at December 31, 1996 was $14.6 million. 
 
Net cash flow provided by operating activities increased from $50.5  
million for the year ended December 31, 1995 to $59.8 million for the  
year ended December 31, 1996.  This $9.3 million increase was primarily  
due to the additional cash flow generated by the greater number of  
properties in service during the latter period. 

                                -26-

<PAGE>

Net cash used in investing activities decreased from $281.9 million for  
the year ended December 31, 1995 to $265.4 million for the year ended  
December 31, 1996.  This decrease was a result of the $125.9 million  
investment made in March 1995 in connection with the acquisition of the  
Lingerfelt portfolio, while there was no similar portfolio acquisition  
made in 1996.  This decrease was partly offset by the increase in  
acquisition, development and property investment from $156.9 for the  
year ended December 31, 1995 to $265.4 million for the year ended  
December 31, 1996. 
 
Net cash provided by financing activities decreased from $216.9 million  
for the year ended December 31, 1995 to $214.6 million for the year  
ended December 31, 1996.  This decrease is consistent with the decrease  
in investing activities. 
 
The Company believes that its undistributed cash flow from operations  
are adequate to fund its short-term liquidity requirements. 
 
The Company has funded its long-term liquidity requirements such as  
property acquisition and development activities primarily through its  
$250 million Line of Credit. This Line matures on June 15, 1998, subject  
to the Company's option to extend the maturity of the loan as described  
below.  As of December 31, 1996, $241.7 million was outstanding under  
the Line of Credit.  The Line of Credit is recourse to the Company only  
with respect to 50% of the outstanding principal amount thereof.  Funds  
borrowed under the Line of Credit bear interest at an annual rate of 175  
basis points over LIBOR.  Subject to certain conditions and the payment  
of a fee equal to 0.5% of the then outstanding loan balance, the Company  
may exercise a one-time option to convert the loan balance into a two- 
year term loan upon the maturity of the Line of Credit.  Following such  
conversion, the interest rate on the term loan would be LIBOR plus 4%. 
 
In December 1996, the Company closed on an $80 million secured Line of  
Credit.  The Line matures on December 13, 1998, however, at any time  
prior to December 13, 1998, maturity may be extended for one year  
subject to certain conditions and the payment of an extension fee equal  
to 1/4% of the total commitment (as defined).  As of December 31, 1996  
collateral had been approved to enable the Company to borrow up to $56.0  
million, of which $25.0 million was outstanding.  The interest rate on  
the Line of Credit is 1.60% over LIBOR. 
 
Periodically, the Company pays down borrowings on its Line of Credit  
facilities with funds from long term capital sources.  During 1996, the  
Company utilized the funds from $77.6 million of mortgage loans it  
placed in 1996 to paydown the line of credit.  The Company has entered  
into a swap agreement, with a notional amount of $114.5 million, to  
hedge against possible fluctuations in interest rates in anticipation of  
a debt issuance in 1997 for a five to seven year term. 
 
As of December 31, 1996, $240.8 million in mortgage loans were  
outstanding with maturities ranging from 1997 to 2013.  The interest  
rates on $230.4 million of mortgage loans are fixed and range from 6% to  
10%.  Interest rates on $10.4 million of mortgage loans float with LIBOR  
or prime and are subject to certain caps.  The weighted average interest  

                               -27-

<PAGE>

rate for the mortgage loans is 7.7% and the weighted average life is 8  
years. 
 
General 
 
The Company expects to incur variable rate debt, including borrowings  
under the Lines of Credit, from time to time.  The Company believes that  
its existing sources of capital 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 stock,  
preferred stock and debt.  On November 27, 1995, the Company completed a  
follow-on public offering of 7,200,000 common shares resulting in  
proceeds of $140.4 million. The remaining $209.6 million shelf  
registration is available for future offerings.   
 
On February 8, 1996, Moody's Investors Service assigned a prospective  
rating of Ba2 for senior unsecured debt issued by Liberty Property

CALCULATION OF FUNDS FROM OPERATIONS 
 
Management considers funds from operations an appropriate measure of the  
performance of an equity REIT.  Funds from operations is defined by  
NAREIT as net income or loss (computed in accordance with generally  
accepted accounting principles), excluding gains or losses from debt  
restructuring and sales of property plus depreciation and amortization  
excluding the amortization of deferred financing costs and depreciation  
of non-real estate assets.  Funds from operations should not be  
considered as an alternative to net income or as an alternative to cash  
flow or as a measure of liquidity.  Funds from operations for the years  
ended December 31, 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 Predecessor or the  
Company during this period. The Lines of Credit bear interest at a  
variable rate; therefore, the amount of interest payable under the Lines  
of Credit 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.

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, 1996 and 1995, and the  
related consolidated statements of operations, shareholders' equity, and  
cash flows for each of the two years in the period ended December 31,  
1996, and the period June 23, 1994 through December 31, 1994.  We have  
also audited the combined statements of operations, owners' deficit and  
cash flows of the Rouse Group for the period January 1, 1994 through  
June 22, 1994.  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, 1996 and 1995, the consolidated  
results of Liberty Property Trust's operations and cash flows for each  
of the two years in the period ended December 31, 1996 and for the  
period June 23, 1994 through December 31, 1994, and the combined results  
of the Rouse Group's operations and cash flows for the period January 1,  
1994 through June 22, 1994, 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 
AND COMBINED FINANCIAL STATEMENTS OF THE ROUSE GROUP 
 
 
1.   ORGANIZATION 
 
Liberty Property Trust (the "Trust") a self-administered and self- 
managed real estate investment trust (a "REIT"), was formed in the State  
of Maryland on March 28, 1994 and commenced operations on June 23, 1994  
upon completion of its initial public offering of  20,987,500 Common  
Shares of Beneficial Interest (the "Share Offering").  The Trust  
conducts all of its operations, including leasing, property management  
and other services through Liberty Property Limited Partnership (the  
"Operating Partnership" and together with the Trust referred to as the  
"Company"). Simultaneous with the closing of the Share Offering, the  
Company succeeded to substantially all of the interests of Rouse &  
Associates, a general partnership, and certain other entities affiliated  
with Rouse & Associates (collectively the "Rouse Group"). At December  
31, 1996, the Trust owns an 90.02% interest in the Operating Partnership  
as the sole general partner and a .03% interest as a limited partner.   
Concurrent with the Share Offering, the Operating Partnership completed  
a public offering of $230 million of Exchangeable Subordinated  
Debentures (the "Debenture Offering", and, together with the Share  
Offering, the "Offerings") due 2001.  The Debentures are guaranteed by  
the Trust.  After June 23, 1995, the Debentures are exchangeable at any  
time prior to maturity into Common Shares of Beneficial Interest at a  
rate of one share for each $20 outstanding principal amount of  
Debentures, subject to certain adjustments. The Company completed a  
follow-on offering (the "Follow-on Offering") on November 27, 1995,  
which resulted in net proceeds of $131.5 million.  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  
and Mid-Atlantic United States. 
 
The Rouse Group combined financial statements include accounts of the  
properties and entities acquired by the Operating Partnership which are  
considered to be entities under common ownership and management. 
 
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

<PAGE>
interest by the Operating Partnership was accounted for as a  
reorganization of entities under common control which is similar to the  
accounting for a pooling of interests.  As a result, the operations of  
the Rouse Group are included in these Financial Statements. 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 net realizable 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 
 
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. 
 
Earnings per Share 
 
Earnings per share is computed using the weighted average common shares  
and common stock equivalents outstanding during the years ended December  
31, 1996 and December 31, 1995 and for the period from June 23, 1994  
through December 31, 1994.  Fully diluted earnings per share is not  
disclosed because such information is not meaningful.  Earnings per  
share is $1.16 calculated as if the debenture conversions which occurred  
in 1996 had occurred on January 1, 1996. 
 
Income Taxes 
 
The Trust has made an election to be taxed as a Real Estate Investment  
Trust ("REIT") under Sections 856 through 860 of 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  

                                 -38-
<PAGE>
taxable income to its shareholders.  If the Trust fails to qualify as a  
REIT in any taxable year, the Trust will be subject to Federal income  
tax (including any applicable Alternative Minimum Tax) at regular  
corporate rates on its taxable income. Even if the Trust qualifies for  
taxation as a REIT, 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. 
 
The Company paid dividends of $52.6 million, $38.7 million, and $10.2  
million during the years ended December 31, 1996 and 1995 and for the  
period from June 23, 1994 to December 31, 1994.  On a per share basis,  
the Company paid dividends of $1.61, $1.60 and $0.43 during the years  
ended December 31, 1996 and 1995 and for the period from June 23, 1994  
to December 31, 1994.  The portions of the 1996 dividend relating to  
return of capital and earnings and profits are 29.9% and 70.1%,  
respectively. 
 
The Federal tax cost basis of the real estate at December 31, 1996 was  
approximately $1.1 billion. 
 
3.   REAL ESTATE

4.   RELATED PARTY TRANSACTIONS 
 
An affiliated company provides construction services to the Company.   
Amounts paid to this affiliate were $29,717,000 in 1996, $6,245,000 in  
1995, and $2,583,000 in 1994. 
 
During 1995, three properties were purchased from partnerships  
affiliated with Rouse & Associates not included in the Rouse Group.  The  
Rouse principals 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, 1996 and December 31, 1995  
and the period from June 23, 1994 to December 31, 1994 the fees for  
these services were $600,000, $600,000 and $453,000 respectively. At  
December 31, 1995, the Company had a $250,000 receivable from Rouse Kent  
Limited for these management and other services.  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, 1996, the balance of these notes receivable was $7.4  
million. 
 
5.   MORTGAGE LOANS, SUBORDINATED DEBENTURES AND LINES OF CREDIT  
 
Long term indebtedness consists generally of mortgage loans,  
subordinated debentures and Lines of Credit.  The average annualized  
interest rates for the years ended December 31, 1996, 1995, and 1994,  
were approximately 7.6%, 7.8%, and 8.0%  respectively.  Interest expense   
for the years ended December 31, 1996, 1995, and 1994, aggregated  
$38,528,000,  $37,688,000, and $34,243,000, respectively.  Interest  
costs during these periods of $7,708,000, $3,475,000, and $190,000 were  
capitalized.  Cash paid for interest for the years ended December 31,  
1996, 1995, and 1994 was $35,995,000, $33,202,000, and $51,232,000,  
respectively. 
 
Mortgage loans with maturities ranging from 1997 to 2013 are  
collateralized by and in some instances cross collateralized by  
properties with a book value of $314.0 million.  The interest rates on  
$230.4 million of mortgage loans are fixed and range from 6% to 10%.   
Interest rates on $10.4 million of mortgage loans float with LIBOR or  
prime and are subject to certain caps.  The weighted average interest  
rate on the mortgage loans is 7.7% and the weighted average life is 8  
years.

                             ======== 
 
The Debentures are due on June 23, 2001 and are exchangeable for shares  
of the Trust at a rate of one share for each $20 outstanding principal  
amount of Debentures, subject to certain adjustments.  The initial  
interest rate on the Debentures was 8% and increases with increases in  
the dividend payment on the Company's Common Shares of Beneficial  
Interest.  At the current $.41 per share per quarter dividend payment  
rate, the effective interest rate on the Debentures is 8.2%.  During the  
year ended December 31, 1996, the Company paid sums aggregating $1.0  
million to facilitate the conversion of $58.7 million of Debentures into  
2,934,300 common shares. During the year ended December 31, 1996, $2.9  
million of related deferred financing costs were written off through  
additional paid-in capital. 
 
The Lines of Credit are composed of two secured lines of credit (the  
"$250 million Line of Credit" and the "$80 million Line of Credit").   
The $250 million Line of Credit is secured and is due on June 15, 1998  
at which time it may be converted into a two year term loan with the  
payment of a conversion fee equal to 1/2% of the then outstanding  
balance.  As of December 31, 1996, the $250.0 million Line of Credit was  
fully collateralized and $241.7 million was outstanding.  The interest  
rate on the $250 million Line of Credit is 30-day LIBOR plus 1.75%  
(7.13% and 7.75% at December 31, 1996 and 1995, respectively). Other  
normal and customary fees apply including an unused line fee. The $250  
million Line of Credit is recourse to the Company only with respect to  
50% of the outstanding principal thereof and is otherwise non-recourse  
subject to certain conditions.  At December 31, 1996, 109  properties  
with a book value of $387.6 million collateralized the $250 million Line  
of Credit. During 1996, the Company closed on an $80 million Line of  
Credit.  The $80 million Line of Credit is secured and is due on  
December 13, 1998.  At any time prior to December 13, 1998, maturity may  
be extended for one year subject to certain conditions and the payment  
of an extension fee equal to 1/4% of the total commitment.  As of  
December 31, 1996, collateral had been approved to enable the company to  
borrow up to $56.0 million, of which $25.0 million was outstanding.  The  
interest rate on the $80 million Line of Credit is 90-day LIBOR plus  
1.60% (7.13% at December 31, 1996).  At December 31, 1996, 23 properties  
with a book value of $64.5 million, and 2 development properties with a  
book value of $3.9 million collateralized the $80 million Line of  
Credit.

In 1994, the Company recognized a gain on extinguishment of debt which  
resulted primarily from the payment of mortgage notes and notes payable  
including penalties and accrued interest at a discount with $451.8  
million in proceeds obtained from the issuance of shares and the  
Debentures. 
 
The fair value of the Debentures at December 31, 1996 was $220.4 million  
based on the closing bid price of the security on the New York Stock  
Exchange.  The fair values of the mortgages and Lines of Credit were  
estimated using discounted cash flow analysis, based on the Company's  
estimated incremental borrowing rate at December 31, 1996, for similar  
types of borrowing arrangements.  The carrying values of the mortgages  
and the Lines of Credit approximate their fair values. 
 
6.	LEASING ACTIVITY 
 
Future minimum rental payments due from tenants under non-cancellable  
operating leases as of December 31, 1996 are as follows (in thousands): 
 
        1997                 $119,777  
        1998                  107,177

                             ======== 
 
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, persons contributing  
interest in properties to the Operating Partnership have received  
limited partnership interests in the Operating Partnership.  The  
aggregate outstanding limited partnership interests have the same  
economic characteristics as would 3,470,961 common shares of the Trust,  
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 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  

                              -42-

<PAGE>

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. 
 
The Company's 1995 Share Incentive Plan has authorized the grant of  
options to executive officers, other key employees, non-employee  
trustees and consultants for up to 2,100,000 shares of the Company's  
common shares of beneficial interest.  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: risk-free interest rate of 6.2%;  
dividend yield of 7.0%; volatility factor of the expected market price  
of the Company's common stock of .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 stock  
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 stock options. 
 
For purposes of pro forma disclosures, the estimated fair value of the  
options is amortized to expense over the options' vesting period.  The  
Company's pro forma information follows (in thousands, except for per  
share amounts):

An additional 511,887, 632,400 and 1,335,000 shares were reserved for  
issuance for future grants from the option plan at December 31, 1996,  
1995 and 1994, respectively. 
 
9.   COMMITMENTS AND CONTINGENCIES 
 
All of the Properties have been subject to Phase I Environmental  
Assessments ("Phase I Assessments") performed and obtained in  
contemplation of the formation or acquisitions.  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. 
 
The Trust is not a party to any material legal proceedings.  In the  
ordinary course of business, the Operating Partnership is party to  
ordinary routine litigation incidental to its business and in addition

The Company has entered into an interest rate swap agreement to hedge  
against possible fluctuations in interest rates in anticipation of a  
$120 million debt issuance in 1997 for a five to seven year term.  The  
securities underlying the interest rate swap agreement, with a notional  
amount of $114.5 million, are 5.875% US Treasury Securities maturing on  
February 15, 2004.  Gain or loss on this hedging transaction is being  
deferred and will be amortized as adjustments to interest expense  
commencing on the date of issuance of the debt and over the term of the  
debt.  At December 31, 1996, the Company had one swap transaction  
outstanding, and approximately $645,000 in unrealized gain has been  
deferred.

                        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, 1996 and 1995, and the related consolidated statements of  
operations, owners' equity, and cash flows for each of the two years in  
the period ended December 31, 1996, and the period June 23, 1994 through  
December 31, 1994.  We have also audited the combined statements of  
operations, owners' deficit and cash flows of the Rouse Group for the  
period January 1, 1994 through June 22, 1994.  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, 1996 and 1995, the  
consolidated results of Liberty Property Limited Partnership's  
operations and cash flows for each of the two years in the period ended   
December 31, 1996 and for the period June 23, 1994 through December 31,  
1994, and the combined results of the Rouse Group's operations and cash  
flows for the period January 1, 1994 through June 22, 1994, 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 AND COMBINED FINANCIAL STATEMENTS OF THE ROUSE GROUP 
 
 
1.   ORGANIZATION 
 
Liberty Property Trust (the "Trust") a self-administered and self- 
managed real estate investment trust (a "REIT"), was formed in the State  
of Maryland on March 28, 1994 and commenced operations on June 23, 1994  
upon completion of its initial public offering of 20,987,500 Common  
Shares of Beneficial Interest (the "Share Offering").  The Trust  
conducts all of its operations, including leasing, property management  
and other services through Liberty Property Limited Partnership (the  
"Operating Partnership" and together with the Trust referred to as the  
"Company"). Simultaneous with the closing of the Share Offering, the  
Company succeeded to substantially all of the interests of Rouse &  
Associates, a general partnership, and certain other entities affiliated  
with Rouse & Associates (collectively the "Rouse Group"). At December  
31, 1996, the Trust owns an 90.02% interest in the Operating Partnership  
as the sole general partner and a .03% interest as a limited partner.   
Concurrent with the Share Offering, the Operating Partnership completed  
a public offering of $230 million of Exchangeable Subordinated  
Debentures (the "Debenture Offering", and, together with the Share  
Offering, the "Offerings") due 2001.  The Debentures are guaranteed by  
the Trust.  After June 23, 1995, the Debentures are exchangeable at any  
time prior to maturity into Common Shares of Beneficial Interest at a  
rate of one share for each $20 outstanding principal amount of  
Debentures, subject to certain adjustments. The Company completed a  
follow-on offering (the "Follow-on Offering") on November 27, 1995,  
which resulted in net proceeds of $131.5 million. 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  
and Mid-Atlantic United States. 
 
The Rouse Group combined financial statements include accounts of the  
properties and entities acquired by the Operating Partnership which are  
considered to be entities under common ownership and management. 
 
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.  The acquisition of the Rouse Group interest by the  

                               -68-
<PAGE>

Operating Partnership was accounted for as a reorganization of entities  
under common control which is similar to the accounting for a pooling of  
interests.  As a result, the operations of the Rouse Group are included  
in these Financial Statements. 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 net realizable 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 
 
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. 
 
3.   REAL ESTATE 
 
At December 31, 1996 and 1995, the Company owned and operated industrial  
and office properties within suburban mixed use developments or business  
parks.  The carrying value of these properties by type is as follows (in  
thousands):

feet of leasable space.  As of December 31, 1996 approximately $85.6  
million has been expended for the development of these projects and an  
additional $68.2 million is required for completion. 
 
4.   RELATED PARTY TRANSACTIONS

1995, and $2,583,000 in 1994. 
 
During 1995, three properties were purchased from partnerships  
affiliated with Rouse & Associates not included in the Rouse Group.  The  
Rouse principals 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, 1996 and December 31, 1995,  
and the period from June 23, 1994 to December 31, 1994, the fees for  
these services were $600,000, $600,000 and $453,000, respectively.  At  
December 31, 1995, the Company had a $250,000 receivable from Rouse Kent  
Limited for these management and other services.  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, 1996, the balance of these notes receivable was $7.4  
million. 
 
5.   MORTGAGE LOANS, SUBORDINATED DEBENTURES AND LINES OF CREDIT  
 
Long term indebtedness consists generally of mortgage loans,

The Debentures are due on June 23, 2001 and are exchangeable for shares  
of the Trust at a rate of one share for each $20 outstanding principal  
amount of Debentures, subject to certain adjustments.  The initial  
interest rate on the Debentures was 8% and increases with increases in  
the dividend payment on the Company's Common Shares of Beneficial  
Interest.  At the current $.41 per share per quarter dividend payment  
rate, the effective interest rate on the Debentures is 8.2%.  During the  
year ended December 31, 1996, the Company paid sums aggregating $1.0  
million to facilitate the conversion of $58.7 million of Debentures into  
2,934,300 common shares.  During the year ended December 31, 1996, $2.9  
million of related deferred financing costs were written off through  
additional paid-in capital. 
 
The Lines of Credit are composed of two secured lines of credit (the  
"$250 million Line of Credit" and the "$80 million Line of Credit").   
The $250 million Line of Credit is secured and is due on June 15, 1998  
at which time it may be converted into a two year term loan with the  
payment of a conversion fee equal to 1/2% of the then outstanding  
balance.  As of December 31, 1996, the $250 million Line of Credit was  
fully collateralized and $241.7 million was outstanding. The interest  
rate on the $250 million Line of Credit is 30-day LIBOR plus 1.75%  
(7.13% and 7.75% at December 31, 1996 and 1995, respectively). Other  
normal and customary fees apply including an unused line fee. The $250  
million Line of Credit is recourse to the Company only with respect to  
50% of the outstanding principal thereof and is otherwise non-recourse  

                               -71-

<PAGE>

subject to certain conditions.  At December 31, 1996, 109 properties  
with a book value of $387.6 million collateralized the $250 million Line  
of Credit.  During 1996, the Company closed on an $80 million Line of  
Credit.  The $80 million Line of Credit is secured and is due on  
December 13, 1998.  At any time prior to December 13, 1998, maturity may  
be extended for one year subject to certain conditions and the payment  
of an extension fee equal to 1/4% of the total commitment.  As of  
December 31, 1996, collateral had been approved to enable the Company to  
borrow up to $56.0 million, of which $25.0 million was outstanding.  The  
interest rate on the $80 million Line of Credit is 90-day LIBOR plus  
1.60% (7.13% at December 31, 1996).  At December 31, 1996, 23 properties  
with a book value of $64.5 million, and 2 development properties with a  
book value of $3.9   million collateralized the $80 million Line of  
Credit. 
 
In 1994, the Company recognized a gain on extinguishment of debt which  
resulted primarily from the payment of mortgage notes and notes payable  
including penalties and accrued interest at a discount with $451.8  
million in proceeds obtained from the issuance of shares and the close  
of the Debenture offering. 
 
The fair value of the Debentures at December 31, 1996 was $220.4 million  
based on the closing bid price of the security on the New York Stock  
Exchange.  The fair values of the mortgages and Lines of Credit were  
estimated using discounted cash flow analysis, based on the Company's  
estimated incremental borrowing rate at December 31, 1996, for similar  
types of borrowing arrangements.  The carrying values of the mortgages  
and the Lines of Credit approximate their fair values. 
 
6.   LEASING ACTIVITY

                             ======== 
 
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 have been subject to Phase I Environmental  
Assessments ("Phase I Assessments") performed and obtained in  

                                -72-

<PAGE>

contemplation of the formation or acquisitions.  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. 
 
The Trust is not a party to any material legal proceedings.  In the  
ordinary course of business, the Operating Partnership is party to  
ordinary routine litigation incidental to its business and in addition  
it is covered by insurance. 
 
The Company has entered into an interest rate swap agreement to hedge  
against possible fluctuations in interest rates in anticipation of a  
$120 million debt issuance in 1997 for a five to seven year term.  The  
securities underlying the interest rate swap agreement, with a notional  
amount of $114.5 million, are 5.875% US Treasury securities maturing on  
February 15, 2004.  Gain or loss on this hedging transaction is being  
deferred and will be amortized as adjustments to interest expense  
commencing on the date of issuance of the debt and over the term of the  
debt.  At December 31, 1996, the Company had one swap transaction  
outstanding, and approximately $645,000 in unrealized gain has been  
deferred.

2.    REVOLVING CREDIT FACILITY. 
 
      2.1.  Commitment to Lend; Limitation on Total Commitment.  Subject  
to the provisions of 2.5 and the other terms and conditions set forth in  
this Agreement, each of the Banks severally agrees to lend to the  
Borrower and the Borrower may borrow, repay, and reborrow from time to  
time between the Effective Date and the Maturity Date (or, if the Term  
Extension Option is exercised, the Term Extension Maturity Date) upon  
notice by the Borrower to the Agent given and approved by the Agent in  
accordance with 2.5, such sums as are requested by the Borrower up to a  
maximum aggregate principal amount outstanding (after giving effect to  
all amounts requested) at any one time equal to such Bank's Commitment,  
provided that the sum of the outstanding amount of the Loans (after  
giving effect to all amounts requested) shall not at any time exceed the  
Maximum Loan Amount. The Loans shall be made pro rata in accordance with  
each Bank's Commitment Percentage and the Banks shall at all times  
immediately adjust inter se any inconsistency between each Bank's  
outstanding principal amount and each Bank's Commitment. Each request  
for a Loan hereunder shall constitute a representation and warranty by  
the Borrower that the conditions set forth in 10 or 11 (whichever is  
applicable) have been satisfied on the date of such request and will be  
satisfied on the proposed Drawdown Date of the requested Loan, provided  
that the making of such representation and warranty by Borrower shall  
not limit the right of any Bank not to lend upon a determination by the  
Requisite Banks that such conditions have not been satisfied. 
 
      2.2.  Reduction of Commitment.  The Borrower shall have the right  
effective upon the extension of the Maturity Date pursuant to 3.1, upon  
at least ten (10) Business Days' prior written notice to the Agent, to  
reduce by $1,000,000 or an integral multiple of $100,000 in excess  
thereof the unborrowed portion of the then Total Commitment, provided  
that the Total Commitment shall not be reduced to less than $50,000,000,  
whereupon the Commitments of the Banks shall be reduced pro rata in  
accordance with their respective Commitment Percentages by the amount  
specified in such notice. Upon the effective date of any such reduction,  
the Borrower shall pay to the Agent for the respective accounts of the  
Banks the full amount of any commitment fee then accrued on the amount  
of the reduction. No reduction of the Commitments may be reinstated. 
 
      2.3.  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. A  
Note shall be payable to the order of each Bank in a 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  
Drawdown 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. 
 
      2.4.  Interest on Loans. 
 
            (a)  Each Base Rate Loan shall bear interest for the period  
commencing with the Drawdown 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 Drawdown Date thereof and ending on the last  
day of the Interest Period with respect thereto at the rate of 160 basis  
points 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. 
 
      2.5.  Requests for Loans. 
 
            (a) The Borrower shall give to the Agent written notice in  
the form of Exhibit B hereto of each Loan requested hereunder (a "Loan  
Request") no less than (a) two (2) Business Days prior to the proposed  
Drawdown Date of any Base Rate Loan and (b) four (4) Eurodollar Business  
Days prior to the proposed Drawdown Date of any Eurodollar Rate Loan.  
Each such notice shall specify (i) the principal amount of the Loan  
requested, (ii) the proposed Drawdown Date of such Loan, (iii) the  
Interest Period for such Loan, and (iv) the Type of such Loan, and shall  
be accompanied by a statement in the form of Exhibit C hereto signed by  
a Responsible Officer setting forth in reasonable detail computations  
evidencing compliance with the covenants contained in 9.1 through 9.7  
hereof after giving effect to such requested Loan (a "Compliance  
Certificate").  Promptly upon receipt of a Loan Request, the Agent shall  
notify each of the Banks thereof and each Bank shall immediately notify  
the Agent if it believes that any of the conditions contained in 11 of  
this Agreement has not been met or waived.  If such a notice is given  
the Requisite Banks shall promptly determine whether all of the  
conditions contained in 11 of this Agreement have been met or waived.   
If no such notice is given by any Bank or if following such notice the  
Requisite Banks determine that the conditions contained in 11 have been  
met or waived, each of the Banks shall be obligated to fund its  
Commitment Percentage of the requested Loans.  Each such Loan Request  
shall be irrevocable and binding on the Borrower and the Borrower shall  
be obligated to accept the Loan requested from the Banks on the proposed  
Drawdown Date. Each Loan Request shall be in a minimum aggregate amount  
of $3,000,000 or an integral multiple of $1,000,000 in excess thereof. 
 
             (b) Notwithstanding anything contained in 2.5 (a) to the  
contrary, in the event that the making of a requested Loan would cause  
non-compliance with any of the covenants contained in 9.1 through 9.7  
hereof, the Agent may, in its sole discretion, reduce the amount of the  
Loan Request to an amount which would enable the Borrower to maintain  
compliance with such otherwise defaulted covenant or covenants and  
Borrower shall accept the Loan made pursuant to such reduced Loan  
Request. 
 
      2.6.   Conversion Options. 
 
             (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 2.6(b) and 2.6(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 Commitment 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 $3,000,000 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 2.6 (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 request a Eurodollar Rate Loan  
pursuant to 2.5, elect to convert a Base Rate Loan to a Eurodollar Rate  
Loan pursuant to 2.5(a) or elect to continue a Eurodollar Rate Loan  
pursuant to 2.6(b) if, after giving effect thereto, there would be  
greater than six (6) Eurodollar Rate Loans outstanding. Any Loan Request  
for a Eurodollar Rate Loan that would create greater than six (6)  
Eurodollar Rate Loans outstanding shall be deemed to be a Loan Request  
for a Base Rate Loan. 
 
      2.7.   Funds for Loans. 
 
             (a) Subject to 2.5 and other provisions of this Agreement,  
not later than 11:00 a.m. (Boston time) on the proposed Drawdown Date of  
any Loans, 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 Percentage of the amount of the requested Loans. Upon  
receipt from each Bank of such amount, and upon receipt of the documents  
required by 10 or 11 (whichever is applicable) 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 any Drawdown Date the amount of its Commitment Percentage of  
the requested Loans 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 Percentage of any requested Loans but shall not  
obligate any other Bank or Agent to fund more than its Commitment  
Percentage of the requested Loans or to increase its Commitment  
Percentage. 
 
             (b) The Agent may, unless notified to the contrary by any  
Bank prior to a Drawdown Date, assume that such Bank has made available  
to the Agent on such Drawdown Date the amount of such Bank's Commitment  
Percentage of the Loans to be made on such Drawdown 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 Drawdown 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 Percentage of  
such Loans, times (iii) a fraction, the numerator of which is the number  
of days or portion thereof that elapsed from and including such Drawdown  
Date to the date on which the amount of such Bank's Commitment  
Percentage of such Loans 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; Term Extension Option. (a) 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 unless prior to the Maturity Date the  
Borrower elects the Term Extension Option pursuant to this 3.1. 
 
             (b)  At any time prior to the Maturity Date, provided that  
no Default or Event of Default has occurred and is continuing, the  
Borrower shall have the option to extend the Maturity Date for one (1)  
year subject to satisfaction of the following conditions: (a) the  
Borrower shall acquire the Required Interest Rate Contracts, and (b) not  
more than an aggregate of $10,000,000 of other Recourse Indebtedness of  
Borrower has a maturity which is sooner than ninety days after the  
extended Maturity Date.  The Term Extension Option shall be exercised by  
written notice to the Agent at least ten (10) Business Days prior to the  
Maturity Date.  Such written notice must be accompanied by payment of a  
Term Extension option fee equal to twenty-five basis points (0.25%) of  
the Total Commitment to be in effect after such extension taking into  
account any reduction pursuant to 2.2. 
 
      3.2.   Mandatory Repayments of Loan. If at any time the sum of the  
outstanding amount of the Loans exceeds the Maximum Loan Balance, then  
the Borrower shall immediately pay the amount of such excess to the  
Agent for the respective accounts of the Banks for application to the  
Loans. 
 
      3.3.   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 3.3 may be made only  
on the last day of the Interest Period relating thereto, except as set  
forth below in this 3.3. 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 3.3 of any Base Rate Loans and  
four (4) Eurodollar Business Days, notice of any proposed repayment  
pursuant to this 3.3 of any Eurodollar Rate Loans, specifying the  
proposed date of payment of Loans and the principal amount to be paid.  
Each such partial prepayment of the Loans shall be in an integral  
multiple of $100,000 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: 
 
             (i)   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.  (For  
all purposes of this Section, any Loan not being made as a Eurodollar  
Rate Loan in accordance with the Loan Request therefor, as a result of  
Borrower's cancellation thereof, shall be treated as if such Eurodollar  
Rate Loan had been prepaid.)  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 on a Eurodollar Rate Loan in the same amount for the same period  
if the Eurodollar Rate were set on the Prepayment Date. 
 
             (ii)  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. 
 
             (iii) 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.   Revolving Credit Facility Fees and Agent's Fee. The  
Borrower agrees to pay to the Agent a revolving credit facility fee and  
agency fees in the amounts specified in the agreement regarding fees  
between the Agent and the Borrower and the Agent shall be responsible  
for any facility fees which it may agree to pay to the other Banks which  
become a party to this Agreement. 
 
      4.2.   Commitment Fee.  The Borrower shall pay to the Agent for  
the accounts of the Banks in accordance with their respective Commitment  
Percentages a commitment fee calculated at the rates set forth below per  
annum on the daily amount by which the Total Commitment (as it may have  
been reduced pursuant to 2.2) exceeds the outstanding amount of Loans  
(the "Unused Amount"):  
 
        Unused Amount                              Fee Rate 
 
less than 1/3 of Total Commitment               15 basis points 
at least 1/3 of Total Commitment 
   but less than 2/3 of Total Commitment        20 basis points 
at least 2/3 of Total Commitment                25 basis points 
 
The commitment fee shall not accrue until March 1, 1997.  Thereafter,  
the commitment fee shall be payable on the basis of the applicable  
annual rate quarterly in arrears on the first day of each calendar  
quarter for the immediately preceding calendar quarter commencing on the  
first such date following the date hereof, with a final payment on the  
Maturity Date or, if the Term Extension Option is exercised, the Term  
Extension Maturity Date or any earlier date on which the Commitments  
shall terminate. 
 
4.3.  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, 4.5 and 4.6) 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. 
 
4.4.  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. 
 
4.5.  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. 
 
      4.6.   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. 
 
      4.7.   Certificate. A certificate setting forth any additional  
amounts payable pursuant to 4.5 or 4.6 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. 
 
      4.8.   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 a borrowing or conversion after the Borrower has  
given (or is deemed to have given) a Loan Request or 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. 
 
      4.9.   Interest or 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 rate of  
interest otherwise payable hereunder 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. 
 
      4.10.  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 Loan  
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.   
 
      4.11.  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 4.11, 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. 
 
      4.12.  Replacement of Banks.  If any of the Banks shall make a  
notice or demand upon the Borrower pursuant to 4.5, 4.6, or 4.11 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 plus the accrued commitment fee  
under 4.2 allocated to the assigning Bank. 
 
5.    COLLATERAL SECURITY; NO LIMITATION ON RECOURSE. 
 
      5.1.   Collateral Security. The Obligations shall be secured by  
(i) a perfected first priority lien and security interest to be held by  
the Agent (subject only to Permitted Liens) in the Mortgaged Properties,  
pursuant to the terms of the Security Documents, (ii) a perfected first  
priority lien and security interest to he held by the Agent in the  
Leases and rents pursuant to the Assignments of Leases and Rents, and  
(iii) the Guaranties.  Each of the Security Documents shall secure all  
of the Obligations and Allocated Loan Amounts shall not be deemed to in  
any way limit the amount of the Obligations secured pursuant to any  
Security Documents. 
 
      5.2.   No Limitation on Recourse. Notwithstanding the foregoing  
Collateral, 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. 
 
      5.3.   Additional Properties.

in 5.4. In the event that the Requisite Banks grant such approval and  
all of the conditions set forth in 5.4 are satisfied, the Agent shall  
notify the Borrower and within ten (10) days thereafter the Mortgagor  
shall execute and deliver to the Agent a Security Deed, an Assignment of  
Rents and Leases and UCC-1 Financing Statements, which Security  
Documents shall be in substantially the form of the Security Documents  
executed and delivered herewith with such changes as the Agent may deem  
desirable to address the laws of the State where the Additional Property  
is located or the factual circumstances of the Additional Property. Such  
Additional Properties shall be deemed to be Mortgaged Properties upon  
the recording and filing of such Security Documents and the Agent's  
receipt of satisfactory evidence thereof. 
 
      5.4.   Conditions to Approval of Additional Properties.  Prior to  
acceptance of any Real Estate Asset to become an Additional Property

and the Agent as to the matters described on Exhibit E relating to the  
Loan Documents executed by Borrower with respect to the Additional  
Property and relating to the laws of the state where the Additional  
Property is located. 
 
      5.5.   Release of Mortgaged Properties. The Borrower may request  
that the Agent release any Mortgaged Property from the lien of the  
Security Documents and the Agent shall approve any such request provided  
that there is then no continuing Default or Event of Default under this  
Agreement and the requested release will not result in any Default or  
Event of Default under this Agreement and the Borrower delivers to the  
Agent a pro-forma Compliance Certificate reasonably satisfactory to the  
Agent demonstrating that the requested release will not result in a  
violation of any of the covenants in 9.1 through 9.7.  The Borrower may  
request releases of a portion of a Mortgaged Property consisting of  
undeveloped land to be developed by Borrower or sold provided that in  
addition to the requirements set forth above, the Borrower shall also

the Title Policy; (ii) an updated Appraisal of the remaining portion of  
the Mortgaged Property and (iii) evidence that the division of the  
Mortgaged Property pursuant to the requested release will not result in  
violation of any zoning ordinance or other applicable laws and  
ordinances.  If the Borrower shall request the release of any Mortgaged  
Property which is adjacent to any other Mortgaged Property which is not  
to be simultaneously released, the Agent may require the establishment  
of appropriate easements and maintenance agreements satisfactory to the  
Agent relating to any shared utilities, drainage facilities, access  
drives or walks, parking areas or other shared facilities.

Based on the information contained in the Environmental Reports,  
Borrower makes the following representations and warranties:

none of the Borrower, the Guarantors or the Related Companies has  
received written notice from any third party including, without  
limitation any federal, state or local governmental authority with  
respect to any of the Mortgaged Properties or otherwise if the same  
would have a Material Adverse Effect, (i) that it has been identified by

federal, state or local agency or other third party has conducted or has  
ordered that the Borrower, any Guarantor or any of the Related Companies  
conduct a remedial investigation, removal or other response action  
pursuant to any Environmental Law; or (iii) that it is or shall be a  
named party to any claim, action, cause of action, complaint, or legal  
or administrative proceeding (in each case, contingent or otherwise)  
arising out of any third party's incurrence of costs, expenses, losses  
or damages of any kind whatsoever in connection with the release of  
Hazardous Materials. 
 
             (c)  Except as set forth on Schedule 6.18 attached hereto  
and/or in the Environmental Reports, (i) to the best of Borrower's  
knowledge no portion of the Real Estate has been used for the handling,  
processing, storage or disposal of Hazardous Materials except in  
material compliance with applicable Environmental Laws; and except as  
set forth on Schedule 6.18, no underground tank or other underground  
storage receptacle for Hazardous Materials is located on any portion of  
the Real Estate; (ii) in the course of any activities conducted by the  
Borrower, any Guarantor, any of the Related Companies or the operators  
of any Real Estate, or to the best of Borrower's knowledge, any ground  
or space tenants on any Real Estate, no Hazardous Materials have been  
generated or are being used on the Real Estate except in material  
compliance with applicable Environmental Laws; (iii) there has been no

or the environment; (iv) to the best of Borrower's knowledge, there have  
been no Releases on, upon, from or into any real property in the

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.

applicable environmental clean-up responsibility law or environmental  
restrictive transfer law or regulation, solely by virtue of the

Subsidiaries except for the Related Companies listed on Schedule 1.3 and  
does not have an ownership interest in any entity whose financial  
statements are not consolidated with the Borrower's except for the  
Permitted Joint Ventures listed on Schedule 1.3.  The Company is not a

any limited liability company.  The Company owns no material assets  
other than its partnership interest in Borrower. 
 
      6.20.  Major Leases.  The Borrower has delivered to the Agent  
copies of the Major Leases. 
 
      6.21.  Loan Documents.  All of the representations and warranties

Banks pursuant to or in connection with any of such Loan Documents are  
true and correct in all material respects. 
 
      6.22.  Mortgaged Properties.  The Borrower makes the following  
additional representations and warranties concerning the Mortgaged  
Properties: 
 
             (a)  Off-Site Utilities. All water, sewer, electric, gas,  
telephone and other utilities are installed to the property lines of the  
Mortgaged Properties and, except in the case of drainage facilities, are  
connected to the Buildings located thereon with valid permits and are  
adequate to service the Buildings in full compliance with applicable  
law; and the Buildings are properly and legally connected directly to,  
and served exclusively by, public water and sewer systems. No easements  
over land of others not yet obtained are required for any such  
utilities, and no drainage of surface or other water across land of  
others is required except as disclosed in the Surveys. 
 
             (b) Surveys, Access; Etc.  Since the date of the most  
recent Survey delivered to the Agent with respect to each Mortgaged  
Property, there has been no construction of additional Buildings or  
additions to Buildings on such Mortgaged Property, no takings by eminent  
domain affecting such Mortgaged Property or other changes which may have  
caused such Survey to be no longer accurate. The streets abutting the  
Mortgaged Properties are public roads, to which each of the Mortgaged  
Properties has direct access by trucks and other motor vehicles and by  
foot, or are private ways (with direct access by trucks and other motor  
vehicles and by foot to public roads) to which each of the Mortgaged  
Properties has direct access without charge or liability for maintenance  
or repair. No easements over land of others not yet obtained are  
required for such means of access and egress except as disclosed in the  
Surveys. 
 
             (c)  Independent Building.  The Buildings on each Mortgaged  
Property are fully independent from any other real estate in all  
respects including, without limitation, in respect of structural  
integrity, heating, ventilating and air conditioning, plumbing,  
mechanical and other operating and mechanical systems, and electrical,  
sanitation and water systems, all of which are connected directly to  
off-site utilities located in public streets or ways. The Buildings are  
located on lots which are separately assessed for purposes of real  
estate tax assessment and payment. The Buildings, all Building Service  
Equipment and all paved or landscaped areas related to or used in  
connection with the Buildings are located wholly within the perimeter  
lines of the lot or lots on which the Mortgaged Properties are located  
except as disclosed in the Surveys. 
 
             (d)  Condition of Building; No Asbestos. Except as set  
forth in the engineering reports provided to the Agent and listed on  
Schedule 6.22(d), to the best of Borrower's knowledge there are no  
material defects in the roof, foundation, structural elements and  
masonry walls of the Buildings or their heating, ventilating and air  
conditioning, electrical, sprinkler, plumbing or other mechanical  
systems or their Building Service Equipment; the Buildings are fully  
sprinkled; and no asbestos is located in or on the Buildings except as  
may be disclosed in the Environmental Reports. 
 
             (e)  Building Compliance with Law; Permits.  The Buildings  
as presently constructed and used do not materially violate any  
applicable federal or state law or governmental regulation, or any local  
ordinance, order or regulation the violation of which may materially  
affect the use or the value of the applicable Mortgaged Property,  
including but not limited to laws, regulations, or ordinances relating  
to zoning, building use and occupancy, subdivision control, fire  
protection, health and sanitation; and the zoning laws permit use of the  
Buildings for their current use; there is such number of parking spaces  
on the lot or lots on which the Mortgaged Properties are located as is  
adequate under the zoning laws to permit use of the Buildings for their  
current use; and all private ways providing access to the Mortgaged  
Properties are zoned in a manner which will permit access to the  
Buildings over such ways by trucks and other commercial and industrial  
vehicles. All Permits required for the operation and maintenance of the  
Mortgaged Properties, including without limitation, building permits,  
curb-cut permits, water connection permits, sewer extension or  
connection permits and other permits relating to the use of utilities,  
and permits required under the Federal Clean Air Act, as amended, the  
Federal Clean Water Act, as amended (including, without limitation a  
so-called Section 404 Permit"), and by state law or regulations  
consistent with the requirements of said Acts, have been validly issued  
by the appropriate governmental Persons and are now in full force and  
effect. 
 
             (f)  No Required Real Property Consents, Permits, Etc. The  
Borrower has received no notices of, nor has any knowledge of, any  
Permits, utility installations and connections (including, without  
limitation, drainage facilities, curb cuts and street openings), or  
private consents required for the maintenance, operation, servicing and  
use of the Mortgaged Properties for their current use which have not  
been granted, effected, or performed and completed (as the case may be)  
or any fees or charges therefor which have not been fully paid. 
 
             (g)  Suits; Judgments.  There are no outstanding material  
notices, suits, orders, decrees or judgments relating to zoning,  
building use and occupancy, subdivision control, fire protection,  
health, sanitation, or other violations affecting, against, or with  
respect to, the Mortgaged Properties or any part thereof. 
 
             (h)  Insurance.  The Borrower has not received any notices  
from any insurer or its agent requiring performance of any work with  
respect to the Mortgaged Properties or canceling or threatening to  
cancel any policy of insurance. 
 
             (i)  Real Property Taxes; Special Assessments.  There are  
no unpaid or outstanding real estate or other taxes or assessments on or  
against the Mortgaged Properties or any part thereof which are payable  
by Borrower or tenants (except only real estate taxes not yet due and  
payable). There are no betterment assessments or other special  
assessments presently pending with respect to any portion of the  
Mortgaged Properties, and Borrower has received no notice of any such  
special assessment being contemplated. 
 
             (j)  Historic Status.  The Buildings are not historic  
structures or landmarks, and the Mortgaged Properties are not within any  
historic district pursuant to any federal, state or local law or  
governmental regulation. 
 
             (k)  Domain.  There are no pending eminent domain  
proceedings against the Mortgaged Properties or any part thereof, and,  
to the Borrower's knowledge, no such proceedings are presently  
threatened or contemplated by any taking authority. 
 
             (l)  Leases.  A rent roll with respect to all Leases of any  
portion of the Mortgaged Properties (current as of the date set forth  
thereon) is accurate and completely set forth in Schedule 6.22(1) as the  
same shall be supplemented each fiscal quarter by a certificate signed  
by an authorized officer of Borrower. The Leases reflected on such rent  
roll constitute the sole and complete agreements and understandings  
relating to leasing or licensing of space in the Buildings or otherwise  
at the Mortgaged Properties. The Borrower has delivered to the Agent a  
true and complete copy of all Major Leases. There are no occupancies,  
rights, privileges or licenses in or to the Buildings or any other part  
of the Mortgaged Properties other than pursuant to the Leases reflected  
on the rent roll set forth in Schedule 6. 22(1). Except as set forth in  
Schedule 6.22(1) the Leases reflected on the Schedule 6.22(1) rent roll  
are in full force and effect, in accordance with their respective terms,  
without any payment default or any other material default thereunder,  
nor are there any defenses, counterclaims, offsets, concessions or  
rebates available to any tenant thereunder, and the Mortgagor has not  
given or made, or received, any notice of default, or any material  
claim, which remains uncured or unsatisfied, with respect to any of the  
Major Leases and, to the best of the Borrower's knowledge there is no  
basis for any such claim or notice of default by any tenant. The  
Schedule 6.22(1) rent roll accurately and completely sets forth all  
rents payable by tenants, no tenant having paid more than one month's  
rent in advance. All tenant improvements or work to be done, furnished  
or paid for by the landlord, or credited or allowed to a tenant, for, or  
in connection with, the Buildings pursuant to any Lease has been  
completed and paid for, or provided for in a manner satisfactory to the  
Agent, or will be paid for by the Borrower in the ordinary course of the  
Borrower's business. No leasing, brokerage or like commissions, fees or  
payments are due from the Borrower in respect of the Leases, or will be  
paid for by the Borrower in the ordinary course of the Borrower's  
business. Except as set forth on the Schedule 6.22(1) rent roll, all  
tenants under all Leases are in occupancy and operating the premises  
covered by such Leases within the permitted uses under such Leases. 
 
             (m)  Service Agreements.  Except as listed on Schedule 6.22  
(m), there are no Service Agreements relating to the operation and  
maintenance of the Mortgaged Properties or any part thereof except  
Service Agreements which may be terminated at the owner's option upon  
not more than 60 days advance notice.  To the best of Borrower's  
knowledge, there are no claims or any bases for claims in respect of the  
Mortgaged Properties or their operation by any party to any Service  
Agreement. 
 
             (n)  Other Material Real Property Agreements; No Options.   
Except as listed on Schedule 6.22(n), there are no material agreements  
pertaining to the Mortgaged Properties or the operation or maintenance  
thereof other than as described in this Agreement (including the  
Schedules hereto) or otherwise disclosed in writing to the Agent by the  
Borrower, and no person or entity has any right or option to acquire any  
of the Mortgaged Properties or any portion thereof or interest therein  
or lease any portion thereof or additional portion thereof or provide  
services thereat.

aware of any litigation or proceedings threatened in writing or any  
pending litigation and proceedings affecting any of the Mortgaged  
Properties or affecting the Borrower, Guarantor or any of the Related  
Companies or to which the Borrower, Guarantor or any of the Related  
Companies is or is to become a party involving an uninsured claim (or as  
to which the insurer reserves rights) against the Borrower, Guarantor or  
any of the Related Companies that at the time of giving of notice could  
reasonably be expected to have a Materially Adverse Effect, and stating  
the nature and status of such litigation or proceedings. The Borrower  
will give notice to the Agent, in writing, in form and detail  
satisfactory to the Agent, within ten (10) days of any judgment not  
covered by insurance, final or otherwise, against the Borrower in an  
amount in excess of $1,000,000. 
 
             (e)  Notice of Default under Major Leases.  The Borrower  
will immediately notify the Agent in writing of the occurrence of any  
failure of any of the Major Tenants to materially comply with any of the  
material terms, covenants, conditions or agreements under any of the  
Major Leases. 
 
      7.6.   Existence; Maintenance of REIT Status; Maintenance of  
Properties.  The Company will do or cause to be done all things  
necessary to preserve and keep in full force and effect its existence as  
a Maryland trust and its status as a self administered real estate  
investment trust under the Code and the existence of Borrower as a  
Pennsylvania limited partnership. The Borrower will do or cause to be  
done all things necessary to preserve and keep in full force all of its  
rights and franchises which in the judgment of the Borrower may be  
necessary to properly and advantageously conduct the businesses being  
conducted by it, the Company or any of the Related Companies. The  
Borrower (a) will cause all of the properties used or useful in the  
conduct of the business of Borrower, the Company or any of the Related  
Companies to be maintained and kept in good condition, repair and  
working order and supplied with all necessary equipment, (b) will cause  
to be made all necessary repairs, renewals, replacements, betterments  
and improvements thereof, all as in the judgment of the Borrower may be  
necessary so that the business carried on in connection therewith may be  
properly and advantageously conducted at all times, and (c) will  
continue to engage primarily in the businesses now conducted by it and  
in related businesses. 
 
      7.7.   Insurance.  The Borrower will maintain insurance on the  
Mortgaged Properties as required by the Security Deeds. With respect to  
other properties and businesses of Borrower, the Guarantors and the  
Related Companies, the Borrower will maintain or cause to be maintained  
insurance with financially sound and reputable insurers against such  
casualties and contingencies as shall be in accordance with the general  
practices of businesses engaged in similar activities in similar  
geographic areas and in amounts, containing such terms, in such forms  
and for such periods as may be reasonable and prudent. 
 
      7.8.   Taxes.  The Borrower will pay real estate taxes, other  
taxes, assessments and other governmental charges against the Mortgaged  
Properties before the same become delinquent, and will duly pay and  
discharge, or cause to be paid and discharged, before the same shall  
become overdue, all taxes, assessments and other governmental charges  
imposed upon it and its other properties, sales and activities, or any  
part thereof, or upon the income or profits therefrom, as well as all  
claims for labor, materials, or supplies that if unpaid might by law  
become a lien or charge upon any of its properties; provided that any  
such tax, assessment, charge, levy or claim with respect to properties  
other than the Mortgaged Properties need not be paid if the validity or  
amount thereof shall currently be contested in good faith by appropriate  
proceedings and if the Borrower shall have set aside on its books  
adequate reserves with respect thereto; and provided further that the  
Borrower will pay all such taxes, assessments, charges, levies or claims  
forthwith upon the commencement of proceedings to foreclose any lien  
that may have attached as security therefor. Promptly after payment of  
real estate taxes, other taxes, assessments and other governmental  
charges against the Mortgaged Properties, Borrower will provide evidence  
of such payments to the Agent, in the form of receipted tax bills or  
other form reasonably acceptable to the Agent. Notwithstanding anything  
contained herein to the contrary, with respect to the Mortgaged  
Properties, Borrower, after receipt of notice from the Agent (which  
notice may be given by the Agent at any time after the occurrence of an  
Event of Default) , shall deposit with Agent, on the first day of each  
month thereafter, a sum determined by Agent to be sufficient to provide,  
in the aggregate, a fund adequate to pay all real estate taxes, other  
taxes, assessments and other governmental charges against the Mortgaged  
Properties at least ten (10) days before the same becomes delinquent;  
and whenever the Agent determines sums accumulated under such escrow to  
be insufficient to meet the obligations for which such deposits were  
made, the Borrower shall pay, on the demand of the Agent, any amount  
required to cover the deficiency therein. 
 
      7.9.   Inspection of Properties and Books.  The Borrower shall  
permit the Banks, through the Agent or any of the Banks' other  
designated representatives, to visit and inspect any of the Mortgaged  
Properties, to examine the books of account of the Borrower, the Company  
and the Related Companies (and to make copies thereof and extracts  
therefrom) and to discuss the affairs, finances and accounts of the  
Borrower with, and to be advised as to the same by, its officers, all at  
such reasonable times and intervals as the Agent or any Bank may  
reasonably request. 
 
      7.10.  Compliance with Laws, Contracts, Licenses, and Permits.   
The Borrower will comply, and will cause each Guarantor and all Related  
Companies to comply, with (a) all applicable laws and regulations now or  
hereafter in effect wherever its business is conducted, including all  
Environmental Laws, (b) the provisions of all applicable partnership  
agreements, charter documents and by-laws, (c) all agreements and  
instruments to which it is a party or by which it or any of its Real  
Estate Assets may be bound including the Leases, and (d) all applicable  
decrees, orders, and judgments except (with respect to (a) through (d)  
above) to the extent such non-compliance would not have a Material  
Adverse Effect. If at any time any Permit from any governmental Person  
shall become necessary or required in order that the Borrower or any  
Guarantor may fulfill or be in compliance with any of its obligations  
hereunder or under any of the Loan Documents, the Borrower will  
immediately take or cause to be taken all reasonable steps within the  
power of the Borrower to obtain such authorization, consent, approval,  
permit or license and furnish the Agent and the Banks with evidence  
thereof. 
 
      7.11.  Use of Proceeds.  Subject to the provisions of 2.5 hereof,  
the proceeds of the Loans shall be used by the Borrower for Permitted  
Acquisitions, Permitted Build-to-Suit Developments and Permitted  
Developments, working capital and other purposes consistent with the  
covenants contained herein. 
 
      7.12.  Appraisals.  The Appraised Values of the Mortgaged  
Properties, including the Appraised Values of Additional Properties  
determined pursuant to Appraisals approved by the Requisite Banks  
pursuant to 10. 14 and 5.4(b), may increase or decrease only upon the  
approval by the Requisite Banks of a new or updated Appraisal of such  
Mortgaged Property. The Agent shall order a new or updated Appraisal of  
a Mortgaged Property (i) promptly following a written request from the  
Borrower, (ii) at any time with respect to any Mortgaged Property if the  
occupied percentage of the gross leasable area of the Buildings on such  
Mortgaged Property for two (2) consecutive fiscal quarters is more than  
20 percentage points lower than the occupancy percentage shown on the  
rent roll for such Mortgaged Property attached as Schedule 6.22(l)  
hereto, (iii) on a date which is approximately 24 months after the date  
of the most recent Appraisal of such Mortgaged Property, and (iv)  
following an Event of Default, if requested by any Bank. The Borrower  
shall provide to the Agent all available information needed to assist in  
the preparation of an Appraisal and shall pay to the Agent on demand all  
reasonable costs of all such Appraisals. 
 
      7.13.  Leases; Lease Approvals.  The Borrower will at all times  
exercise or enforce its material rights under the Leases. The Agent  
shall have the right, and the Borrower hereby authorizes the Agent, to  
communicate directly with any of the tenants or guarantors solely for  
the purpose of verifying any information delivered to the Agent by the  
Borrower concerning the tenants or guarantors, the Buildings, or the  
Leases provided that during the continuance of a Default or Event of  
Default the Agent may contact any tenant or guarantor for any purpose  
contemplated by this Agreement or any of the Security Documents. In the  
event that any of the Leases is terminated, the Borrower will take or  
cause to be taken all steps within the power of the Borrower to market  
and lease the untenanted rentable area of the Buildings. Any proposed  
lease which would be a Major Lease shall be submitted to and approved by  
the Agent prior to execution, along with the most recent financial  
statements of such proposed tenant and any guarantor.  The Borrower will  
not materially adversely amend, terminate, or accept a surrender of any  
Major Lease or release any Major Tenant or waive the material  
performance of a Major Lease by a Major Tenant, in each case without  
prior approval of the Agent. 
 
      7.14.  Further Assurance.  The Borrower will cooperate with the  
Agent and the Banks and execute such further instruments and documents  
and perform such further acts as the Agent and the Banks shall  
reasonably request to carry out to their satisfaction the transactions  
contemplated by this Agreement and the other Loan Documents and the  
granting and perfecting of all liens in the Collateral for the benefit  
of the Agent as agent for the Banks. 
 
      7.15.  Environmental Indemnification.  The Borrower covenants and  
agrees that it will indemnify and hold the Agent and each Bank harmless  
from and against any and all claims, expense, damage, loss or liability  
incurred by the Agent or any Bank (including all reasonable costs of  
legal representation incurred by the Agent or any Bank, but excluding,  
as applicable, for the Agent or a Bank any claim, expense, damage, loss  
or liability as a result of the gross negligence or willful misconduct  
of the Agent or such Bank) relating to (a) any Release or threatened  
Release of Hazardous Substances on any Mortgaged Property or any Real  
Estate; (b) any violation of any Environmental Laws with respect to  
conditions at any Mortgaged Property or any Real Estate or the  
operations conducted thereon; or (c) the investigation or remediation of  
off-site locations at which the Borrower or its predecessors are alleged  
to have directly or indirectly disposed of Hazardous Substances. It is  
expressly acknowledged by the Borrower that this covenant of  
indemnification shall survive any foreclosure or any modification,  
release or discharge of any or all of the Security Documents or the  
payment of the Loans and shall inure to the benefit of the Agent and the  
Banks, and their successors and assigns. 
 
      7.16.  Response Actions.  The Borrower covenants and agrees that  
if any Release or disposal of Hazardous Substances shall occur or shall  
have occurred on any Mortgaged Property or any other Real Estate if the  
same would have a Material Adverse Effect, the Borrower will cause the  
prompt containment and removal of such Hazardous Substances and  
remediation of such Mortgaged Property or Real Estate as necessary to  
comply with all Environmental Laws or to preserve the value of such  
Mortgaged Property or Real Estate to the extent necessary to avoid a  
Material Adverse Effect. 
 
      7.17.  Environmental Assessments.  The Borrower shall diligently  
and continuously comply with all recommendations set forth in the  
Environmental Reports to the extent the Borrower's failure to do so  
would result in a Material Adverse Effect.  If the Agent in its good  
faith judgment, after discussion with the Borrower, has reason to  
believe that the environmental condition of any Mortgaged Property has  
deteriorated, after reasonable notice by the Agent, whether or not a  
Default or an Event of Default shall have occurred, the Agent may, from  
time to time, for the purpose of assessing and ensuring the value of  
such Mortgaged Property, obtain one or more environmental assessments or  
audits of such Mortgaged Property prepared by a hydrogeologist, an  
independent engineer or other qualified consultant or expert approved by  
the Agent to evaluate or confirm (i) whether any Hazardous Substances  
are present in the soil or water at such Mortgaged Property and (ii)  
whether the use and operation of such Mortgaged Property complies with  
all Environmental Laws. Environmental assessments may include without  
limitation detailed visual inspections of such Mortgaged Property  
including, without limitation, any and all storage areas, storage tanks,  
drains, dry wells and leaching areas, and the taking of soil samples,  
surface water samples and ground water samples, as well as such other  
investigations or analyses as the Agent deems appropriate. All such  
environmental assessments shall be at the sole cost and expense of the  
Borrower; provided, however, the Agent may not require environmental  
assessments at the Borrower's expense, with respect to any Mortgaged  
Property, more frequently than annually except (i) during the  
continuance of an Event of Default or (ii) upon the occurrence of a  
Release on any Mortgaged Property. 
 
      7.18.  Employee Benefit Plans. 
 
             (a)  Representation.  The Borrower and its ERISA Affiliates  
do not currently maintain or contribute to any Employee Benefit Plan,  
Guaranteed Pension Plan or Multiemployer Plan. 
 
             (b)  Notice.  The Borrower will obtain the consent of the  
Agent prior to the establishment of any Employee Benefit Plan or  
Guaranteed Pension Plan by the Borrower or any ERISA Affiliate. 
 
             (c)  In General.  Each Employee Benefit Plan maintained by  
the Borrower or any ERISA Affiliate will be operated in compliance in  
all material respects with the provisions of ERISA and, to the extent  
applicable, the Code, including but not limited to the provisions  
thereunder respecting prohibited transactions. 
 
             (d)  Terminability of Welfare Plans.  With respect to each  
Employee Benefit Plan maintained by the Borrower or an ERISA Affiliate  
which is an employee welfare benefit plan within the meaning of 3(1) or  
3(2)(B) of ERISA, the Borrower, or the ERISA Affiliate, as the case may  
be, has the right to terminate each such plan at any time (or at any  
time subsequent to the expiration of any applicable bargaining  
agreement) without liability other than liability to pay claims incurred  
prior to the date of termination. 
 
             (e)  Multiemployer Plans.  Without the consent of the  
Agent, the Borrower will not enter into, maintain or contribute to, any  
multiemployer Plan. 
 
             (f)  Unfunded or Underfunded Liabilities.  The Borrower  
will not, at any time, have accruing unfunded or underfunded liabilities  
with respect to any Employee Benefit Plan, Guaranteed Pension Plan or  
Multiemployer Plan, or permit any condition to exist under any  
Multiemployer Plan that would create a withdrawal liability. 
 
      7.19   Required Interest Rate Contracts.  If the Maturity Date is  
extended pursuant to 3.1(b) commencing on December 13, 1997 and  
thereafter until all Loans are paid in full and the Banks have no  
further obligation to make Loans hereunder, the Borrower shall maintain  
in effect the Required Interest Rate Contracts in form reasonably  
satisfactory to the Agent. 
 
8.    CERTAIN NEGATIVE COVENANTS OF THE BORROWER.  The Borrower  
covenants and agrees as follows, so long as any Loan or Note is  
outstanding or the Banks have any obligation to make any Loans: 
 
      8.1    Restrictions on Indebtedness.  Except with the prior

execution shall have been obtained pending such appeal or review;

securing Indebtedness for such period of time as would permit (assuming  
the giving of appropriate notice if required) the holder or holders  
thereof or of any obligations issued thereunder to accelerate the  
maturity thereof, and in any event, such failure shall continue for  
thirty (30) days, unless the aggregate amount of all such defaulted

described in paragraph (i) of this 12.1 is less than $30,000,000.00; 
 
             (g)  any of the Borrower, the Company or any Guarantor

writing its inability to pay or generally fail to pay its debts as they  
mature or become due, or shall petition or apply for the appointment of  
a trustee or other custodian, liquidator or receiver of any substantial  
part of its properties or shall commence any case or other proceeding  
under any bankruptcy, reorganization, arrangement, insolvency,

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

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

document or instrument;

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

Bank may by notice to the Borrower terminate the unused portion of its  
Commitment hereunder, and upon such notice being given such unused  
portion of its Commitment hereunder shall terminate immediately and such  
Bank shall be relieved of all further obligations to make Loans. No  
termination of such Bank's Commitment hereunder shall relieve the  
Borrower of any of the Obligations or any of its existing obligations to  
such Bank arising under other agreements or instruments. 
 
      12.3.  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, including to the full extent permitted by  
applicable law the obtaining of the ex parte appointment of a  
receiverand, 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. 
 
      12.4.  Distribution of Collateral 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 Security  
Documents, or otherwise with respect to the realization upon any of the  
Collateral, 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 respect of the Collateral 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 Commitment  
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. 
 
      12.5.   Addition of Real Estate Assets to Cure Default.  As an  
alternative to the payment of cash to cure a Default under 9.1 or 9.2  
hereof, the Borrower shall have the right to offer to provide additional  
Collateral to the Agent in the form of Additional Properties pursuant to  
5.3 and 5.4, for the purpose of curing a Default under 9.1 or 9.2  
hereof, if the Borrower designates such Collateral for addition within  
fifteen (15) days after the occurrence of such Default and the Borrower  
executes and delivers to the Agent a Security Deed, an Assignment of  
Leases and Rents, an Indemnity Agreement and UCC-1 Financing Statements  
relating to the Additional Property together with the Certificates and  
opinion described in 5.4(d) and 5.4(e) within thirty (30) days after the  
occurrence of such Default. The Agent and the Banks shall accept and  
approve the addition of such Collateral as a cure for such Default if  
such Collateral shall cure the Default and satisfies the due diligence  
requirements of the Agent and the Requisite Banks, including, without  
limitation, the conditions set forth in 5.4 and those requirements with  
respect to the Mortgaged Properties specified in 10 hereof, within  
ninety (90) days after the occurrence of the subject Default, and at the  
time that such due diligence requirements are so satisfied, no other  
Defaults or Events of Default are continuing. If any such additional  
Collateral is provided to the Agent in accordance with this 12.5, such  
additional Collateral shall, for all purposes hereof, be deemed to be a  
"Mortgaged Property." Until the Agent and Requisite Banks have  
acknowledged in writing the cure of such Default, all consequences of  
such Default hereunder shall be effective (except as provided in 8.7)  
and the Agent may exercise all available remedies except that the  
maturity of the Loans shall not be accelerated based solely on the  
Default which Borrower is diligently attempting to cure hereunder, prior  
to the expiration of said ninety (90) day period. 
 
13.   SETOFF.  Regardless of the adequacy of any Collateral, 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 WITH THE  
PRIOR APPROVAL OF THE AGENT 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.  Notwithstanding the foregoing, no Bank shall exercise  
a right of setoff if such exercise would limit or prevent the exercise  
of any other remedy, right to Collateral or other recourse against the  
Borrower. 
 
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 Commitment 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 Commitment 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. 
 
      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, FNBB 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.  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 it shall  
promptly notify the other Banks of the existence of such Default or  
Event of Default. 
 
      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  
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 Security Documents authorizing the sale or  
other disposition of all or any part of the Collateral and exercise all  
or any such other legal and equitable and other rights or remedies as it  
may have in respect of such Collateral. The Requisite Banks may direct  
the Agent in writing as to the method and the extent of any such sale or  
other disposition, 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.  
The Agent may take such steps as it reasonably determines for the taking  
of possession or title to any Collateral, including the formation of  
trusts or corporation with each Bank having a beneficial interest equal  
to its pro rata percentage of the outstanding Loans. 
 
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

or intangibles taxes in connection with the Security Documents and other  
Loan Documents, or other taxes payable on or with respect to the

title insurance premiums, appraisal fees, engineer's, inspector's and  
surveyor's fees, recording costs and the reasonable fees, expenses and

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, UCC filings or mortgage

connection with its inspection of the Mortgaged Properties, and (i) the  
fees, costs, expenses and disbursements of the Agent incurred in  
connection with the granting of additional Collateral by the Borrower  
pursuant to 12.5 hereof, including, without limitation, the costs  
incurred by the Agent in connection with its inspection of such  
additional Collateral, and the fees and disbursements of the Agent's  
counsel. 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,

indemnification shall only apply to the Agent or Bank being grossly  
negligent or committing willful misconduct), (a) any actual or proposed

respective properties, the violation of any Environmental Law, the

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

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 or the Banks have any obligation to make  
any Loans. 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

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 Commitment 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  
amend Schedules 1 and 1.2 hereof to reflect the recording of any such  
assignments.

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

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 non-preferential effect  
thereof, and that the Obligations evidenced by the new Notes are secured  
by the Collateral with the same validity, enforceability and priority as  
if given on the Effective 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

participation, except that any Bank may sell participations to its  
Affiliated Banks without such consent, (b) each such participation shall  
be in an amount of not less than $9,000,000 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 Commitment Percentage, and (e) no  
participant 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.

or transfer any of its rights or obligations under any of the Loan  
Documents without the prior written consent of each of the Banks.

may disclose information obtained by such Bank pursuant to this  
Agreement to assignees or participants and potential assignees or  
participants hereunder.

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

manner affect such clause or provision in any other jurisdiction, or any  
other clause or provision of this Agreement in any jurisdiction.

In case an Event of Default shall occur and be continuing, the entire  
unpaid principal amount of this Note and all of the unpaid interest  
accrued thereon may become or be declared due and payable in the manner  
and with the effect provided in the Loan Agreement. 
 
The Borrower and all endorsers hereby waive presentment, demand, protest  
and notice of any kind in connection with the delivery, acceptance,  
performance and enforcement of this Note, and also hereby assent to  
extensions of time of payment or forebearance or other indulgences
