The Private Securities Litigation Reform Act of 1995 provides a "safe 
harbor" for forward-looking statements. Certain information included in 
this Quarterly Report on Form 10-Q contain statements that are or will be 
forward-looking, such as statements relating to acquisitions and other 
business development activities, future capital expenditures, financing 
sources and availability, and the effects of regulation (including 
environmental regulation) and competition. Such forward-looking 
information involves important risks and uncertainties that could 
significantly affect anticipated results in the future and, accordingly, 
such results may differ from those expressed in any forward-looking 
statements made by, or on behalf of, the Company. These risks and 
uncertainties include, but are not limited to, uncertainties affecting 
real estate businesses generally (such as entry into new leases, renewals 
of leases and dependence on tenants' business operations), risks relating 
to acquisition, construction and development activities, possible 
environmental liabilities, risks relating to leverage and debt service 
(including availability of financing terms acceptable to the Company and 
sensitivity of the Company's operations to fluctuations in interest 
rates), the potential for the use of borrowings to make distributions 
necessary to qualify as a REIT, dependence on the primary markets in 
which the Company's properties are located, the existence of complex 
regulations relating to status as a REIT and the adverse consequences of 
the failure to qualify as a REIT and the potential adverse impact of 
market interest rates on the market price for the Company's securities.

                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

                                   MARCH 31, 1998

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

The accompanying unaudited consolidated financial statements of Liberty 
Property Trust (the "Trust") and its subsidiaries, including Liberty 
Property Limited Partnership (the "Operating Partnership") (the Trust, 
Operating Partnership and their respective subsidiaries referred to 
collectively as the "Company"), have been prepared in accordance with 
generally accepted accounting principles for interim financial 
information and with the instructions to Form 10-Q and Article 10 of 
Regulation S-X. Accordingly, they do not include all of the information 
and footnotes required by generally accepted accounting principles for 
complete financial statements and should be read in conjunction with the 
consolidated financial statements and notes thereto included in the 
Annual Report on Form 10-K of the Trust and the Operating Partnership for 
the year ended December 31, 1997. In the opinion of management, all 
adjustments (consisting solely of normal recurring adjustments) necessary 
for a fair presentation of the financial statements for these interim 
periods have been included. The results of interim periods are not 
necessarily indicative of the results to be obtained for a full fiscal 
year.  Certain amounts from prior periods have been restated to conform 
to current period presentation.

In the fourth quarter of 1997, the Company adopted Statement of Financial 
Accounting Standards No. 128, "Earnings per Share", which replaced the 
calculation of primary and fully diluted income per common share with 
basic and diluted income per common share.  Unlike primary income per 
common share, basic income per common share excludes any dilutive effects 
of options.  Diluted income per common share generally includes the 
weighted average common shares, the effect of the outstanding options, 
and the conversion of the Units and Convertible Debentures into common 
shares, unless the inclusion of such common share equivalents are 
antidilutive for the period(s) presented.

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

The EITF 97-11 ruling "Accounting for Internal Costs Relating to Real 
Estate Property Acquisitions", effective March 19, 1998, requires the 
expensing of internal acquisition costs.  The Company has adopted this 
release as of January 1, 1998 and accordingly, the results of operations 
for the quarter reflect the expensing of internal acquisition costs.  The 
adoption of the ruling did not have a material effect on the results of 
operations for the quarter ended March 31, 1998 and it is not anticipated 
that it will have a material effect on the Company's results of 
operations for future periods.

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

Liberty Property Trust (the "Trust") is a self-administered and self-
managed Maryland real estate investment trust (a "REIT").  Substantially 
all of the Trust's assets are owned directly or indirectly, and 
substantially all of the Trust's operations are conducted directly or 
indirectly, by its subsidiary, Liberty Property Limited Partnership, a 
Pennsylvania limited partnership (the "Operating Partnership" and, 
together with the Trust, the "Company").  At March 31, 1998, the Trust 
owned a 92.38% interest in the Operating Partnership as the sole general 
partner and a 0.02% interest as a limited partner.  The Company provides 
leasing, property management, acquisition, development, construction 
management and design management for a portfolio of industrial and office 
properties which are located principally within the Southeastern, Mid-
Atlantic and Midwestern United States.

On January 22, 1998, the Company sold $75 million principal amount of 
6.375% notes due 2013.  Such notes are subject to mandatory repayment of 
principal to the holders thereof in 2003 pursuant to a call/put option 
relating to such notes. On January 23, 1998, the Company sold $100 
million principal amount of 7.50% notes due 2018.  The aggregate net 
proceeds to the Company from such offerings were approximately $173.3 
million.

NOTE 3 - PRO FORMA INFORMATION (UNAUDITED)
- -----------------------------------------

The following unaudited pro forma information has been prepared assuming 
the common and preferred shares offerings which were consummated in 1997 
and the first three months of 1998 and the acquisitions of 170 properties 
acquired in 1997 and 48 properties acquired during the first three months 
of 1998, had occurred at January 1, 1997.  The 1997 acquisitions were 
acquired for a total investment of $727.9 million and the 1998 
acquisitions were acquired for a total investment of $274.6 million.

                                 (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

Total revenue                          $ 87,101            $ 77,565
Income available to common

Income per share - basic (1)           $   0.40            $   0.35
Income per share - diluted (1)             0.40                0.35

(1)  Income in the per share calculations has been computed after a 
deduction for minority interest.

This pro forma information is not necessarily indicative of what the 
actual results of operations of the Company would have been, assuming the 
Company had completed the common and preferred shares offerings of 1997 
and the first three months of 1998 as of January 1, 1997, nor does it 
purport to represent the results of operations of the Company for future 
periods.

                       LIBERTY PROPERTY LIMITED PARTNERSHIP

               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

                                 MARCH 31, 1998

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

The accompanying unaudited consolidated financial statements of Liberty 
Property Limited Partnership (the "Operating Partnership") and its direct 
and indirect subsidiaries have been prepared in accordance with generally 
accepted accounting principles for interim financial information and with 
the instructions to Form 10-Q and Article 10 of Regulation S-X. 
Accordingly, they do not include all of the information and footnotes 
required by generally accepted accounting principles for complete 
financial statements and should be read in conjunction with the 
consolidated financial statements and notes thereto included in the 
Annual Report on Form 10-K of the Trust and the Operating Partnership for 
the year ended December 31, 1997. In the opinion of management, all 
adjustments (consisting solely of normal recurring adjustments) necessary 
for a fair presentation of the financial statements for these interim 
periods have been included. The results of interim periods are not 
necessarily indicative of the results to be obtained for a full fiscal 
year.  Certain amounts from prior periods have been restated to conform 
to current period presentations.

The EITF 97-11 ruling "Accounting for Internal Costs Relating to Real 
Estate Property Acquisitions", effective Mar0ch 19, 1998, requires the 
expensing of internal acquisition costs.  The Company has adopted this 
release as of January 1, 1998 and accordingly, the results of operations 
for the quarter reflect the expensing of internal acquisition costs.  The 
adoption of the ruling did not have a material effect on the results of 
operations for the quarter ended March 31, 1998 and it is not anticipated 
that it will have a material effect on the Company's results of 
operations for future periods.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND  
RESULTS OF OPERATIONS
- -----------------------------------------------------------------------

The following discussion compares the activities of the Company for the 
three  months ended March 31, 1998 (unaudited) with the activities of the 
Company for the three months ended March 31, 1997 (unaudited).  As a 
result of the significant level of acquisition and development activities 
by the Company in 1998 and 1997, the overall operating results of the 
Company during such periods are not directly comparable.  However, 
certain data, including the "Same Store" comparison, do lend themselves 
to direct comparison.  As used herein, the term "Company" includes the 
Trust, the Operating Partnership and their subsidiaries.

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

RESULTS OF OPERATIONS
- ---------------------

For the three months ended March 31, 1998 compared to the three months 
ended March 31, 1997.
- -----------------------------------------------------------------------

Rental revenues increased from $34.6 million to $61.0 million, or by 76%, 
for the three months ended March 31, 1997 to 1998. This increase is 
primarily due to the increase in the number of properties in operation 

- -15-
<PAGE>

("Operating Properties") during the respective periods. As of March 31, 
1997, the Company had 285 Operating Properties and as of March 31, 1998, 
the Company had 496 Operating Properties. From January 1, 1997 through 
March 31, 1997, the Company acquired or completed the development on 26 
properties, for a Total Investment (as defined below) of approximately 
$158.9 million. From January 1, 1998 through March 31, 1998, the Company 
acquired or completed the development on 55 properties, for a Total 
Investment of approximately $301.6 million. 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.

Operating expense reimbursement increased from $10.8 million to $20.3 
million for the three months ended March 31, 1997 to 1998. This increase 
was a result of the reimbursement from tenants for increases in rental 
property expenses and real estate taxes. The operating expense recovery 
percentage (the ratio of operating expense reimbursement to rental 
property expenses and real estate taxes) increased from 91.0% for the 
three months ended March 31, 1997 to 92.3% for the three months ended 
March 31, 1998 due to the increase in occupancy.

Rental property and real estate tax expenses increased from $11.9 million 
to $21.9 million for the three months ended March 31, 1997 to 1998. This 
increase was due to the increase in the number of properties owned during 
the respective periods.

Property level operating income for the "Same Store" properties 
(properties owned as of January 1, 1997) increased from $31.0 million to 
$32.4 million for the three months ended March 31, 1997 to 1998, an 
increase of 4.3%. This increase was due to increases in the rental rates 
for the properties and increases in occupancy.

Set forth below is a schedule comparing the property level operating 
income for the Same Store properties for the three month periods ended 
March 31, 1998 and 1997.

General and administrative expenses increased from $2.5 million for the 
three months ended March 31, 1997 to $3.4 million for the three months 
ended March 31, 1998.  This $900,000 increase was 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.  
Additionally, the first quarter of 1998 reflects the expensing of 
internal acquisition costs as of January 1, 1998 in compliance with EITF 

- -16-
<PAGE>

97-11, whereas these costs were previously capitalized.  These increases 
are somewhat mitigated by the benefit of certain economies of scale 
experienced by the Company in owning and operating the properties.

Depreciation and amortization expense increased from $8.0 million for the 
three months ended March 31, 1997 to $14.2 million for the three months 
ended March 31, 1998.  This increase was due to an increase in the number 
of properties owned during the respective periods.

Interest expense increased from $12.6 million for the three months ended 
March 31, 1997 to $16.6 million for the three months ended March 31, 
1998. This increase was due to an increase in the average debt 
outstanding for the first quarter of 1997 compared to the first quarter 
of 1998, which equalled $647.7 million and $1,059.5 million, 
respectively, partially offset by reduced interest rates. The reduction 
in interest rates was partially the result of the Company receiving 
investment grade ratings from both Standard & Poor's Rating Group ("S&P") 
and Moody's Investor Service, Inc. ("Moody's") during mid-1997 which 
enabled the Company to access public debt markets and other borrowings 
more economically.

As a result of the foregoing, the Company's operating income increased 
from $24.1 million for the three months ended March 31, 1997 to $43.1 
million for the three months ended March 31, 1998.  In addition, income 
before minority interest for the three months increased from $11.5 
million for the three months ended March 31, 1997 to $26.5 million for 
the three months ended March 31, 1998.

LIQUIDITY AND CAPITAL RESOURCES

As of March 31, 1998, the Company had cash and cash equivalents of $37.1 
million.

Net cash flow provided by operating activities increased from $22.2 
million for the three months ended March 31, 1997 to $49.2 million for 
the three months ended March 31, 1998. This $27.0 million increase was 
primarily due to the cash provided by the additional Operating Properties 
in service during the latter period.

Net cash used in investing activities increased from $107.5 million for 
the three months ended March 31, 1997 to $330.7 million for the three 
months ended March 31, 1998. This increase primarily resulted from 
increased acquisition activity in the first three months of 1998 as 
compared to the first three months of 1997.

Net cash provided by financing activities increased from $85.8 million 
for the three months ended March 31, 1997 to $263.6 million for the three 
months ended March 31, 1998. This increase was attributable to the 
issuance of $175 million principal amount of unsecured notes and the 
issuance of 4,002,128 common shares which generated net proceeds of 
$103.1 million during the three months ended March 31, 1998.

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

The Company funds its long-term liquidity requirements such as property 
acquisition and development activities primarily through its $325.0 
million unsecured line of credit (the "Credit Facility").  The interest 
rate on borrowings under the Credit Facility fluctuates based upon the 
Company's leverage levels or ratings from Moody's and S&P.  On June 23, 
1997, Moody's raised its prospective senior debt rating of the Company to 

- -17-
<PAGE>

Baa3 from Ba2 and on July 22, 1997, S&P assigned a BBB- prospective 
senior debt rating to the Company. At these ratings, the interest rate 
for borrowings under the Credit Facility is 110 basis points over the 
Eurodollar Rate.

Periodically, the Company pays down borrowings on the Credit Facility 
with funds from long term capital sources. In the first quarter of 1998, 
the Company used approximately $216.0 million of the proceeds from the 
common share offerings and from medium-term note issuances to paydown the 
Credit Facility.

As of March 31, 1998, $376.7 million in mortgage loans were outstanding 
with maturities ranging from 1998 to 2018. The interest rates on $351.0 
million of mortgage loans are fixed and range from 6% to 9.13%. Interest 
rates on $25.7 million of mortgage loans float with LIBOR or prime, of 
which $19.1 million is subject to certain caps. The weighted average 
interest rate for the mortgage loans is 7.6%, and the weighted average 
remaining term is 8.0 years.

General

The Company expects to incur variable rate debt, including borrowings 
under the Credit Facility, from time to time. The Company believes that 
its existing sources of capital, including public debt and equity 
markets, will provide sufficient funds to finance its continued 
acquisition and development activities. In this regard, the Company 
continues to evaluate its long-term capital sources which generally 
include the availability of debt financing and access to equity.

In July 1995, the Company filed a shelf registration with the Securities 
and Exchange Commission that enabled the Company to offer up to an 
aggregate of $350.0 million of securities, including common shares of 
beneficial interest, preferred shares of beneficial interest and debt 
(the "Initial Shelf Registration"). 

On February 21, 1997, the Company filed a shelf registration with the 
Securities and Exchange Commission that enables the Company to offer up 
to an aggregate of $850.0 million of securities, including common shares 
of beneficial interest, preferred shares of beneficial interest and debt 
(the "Second Shelf Registration"). 

On December 24, 1997 the Company filed a shelf registration statement 
with the Securities and Exchange Commission that enables the Company to 
offer up to an aggregate of $1.5 billion of securities, including common 
shares of beneficial interest, preferred shares of beneficial interest 
and debt (the "Third Shelf Registration").  The Third Shelf Registration 
Statement became effective on January 4, 1998.  Collectively, the Initial 
Shelf Registration, the Second Shelf Registration and the Third Shelf 
Registration are referred to as the "Shelf Registration Statement."

On January 12, 1998, the Company augmented its medium-term note program 
to enable the Company to offer, in the aggregate, up to $450 million of 
the Operating Partnership's medium-term notes.  Under the program, on 
January 22, 1998, the Company sold $75 million principal amount of 6.375% 
notes due 2013.  Such notes are subject to mandatory repayment of 
principal to the holders thereof in 2003 pursuant to a call/put option 
relating to such notes.  Also under the program, on January 23, 1998, the 
Company sold $100 million principal amount of 7.50% notes due 2018.  The 
aggregate net proceeds to the Company from such offerings were 
approximately $173.3 million.

Calculation of Funds from Operations

Management generally considers Funds from Operations (as defined below) a 
useful financial performance measure of the operating performance of an 
equity REIT, because, together with net income and cash flows, Funds from 
Operations provides investors with an additional basis to evaluate the 
ability of a REIT to incur and service debt and to fund acquisitions and 
capital expenditures.  Funds from Operations is defined by NAREIT as net 
income or loss after preferred dividends (computed in accordance with 
generally accepted accounting principals ("GAAP")), excluding gains (or 
losses) from debt restructuring and sales of property, plus real-estate 
related depreciation and amortization and minority interest and excluding 
significant non-recurring events that materially distort the comparative 
measurement of the Company's performance over time.  Funds from 
Operations does not represent net income or cash flows from operations as 
defined by GAAP and does not necessarily indicate that cash flows will be 
sufficient to fund cash needs.  It should not be considered as an 
alternative to net income as an indicator of the Company's operating 
performance or to cash flows as a measure of liquidity.  Funds from 
Operations also does not represent cash flows generated from operating, 
investing or financing activities as defined by GAAP.  Funds from 
Operations for the three months ended March 31, 1998 and March 31, 1997 
are as follows:

INFLATION
- ---------

Inflation has remained relatively low during the last three years, and as 
a result, it has not had a significant impact on the Company during this

<PAGE>

period. The Credit Facility bears interest at a variable rate; therefore, 
the amount of interest payable under the Credit Facility will be 
influenced by changes in short-term interest rates, which tend to be 
sensitive to inflation. To the extent an increase in inflation would 
result in increased operating costs, such as in insurance, real estate 
taxes and utilities, substantially all of the tenants' leases require the 
tenants to absorb these costs as part of their rental obligations. In 
addition, inflation also may have the effect of increasing market rental 
rates.

      (a)  The Company will not, and will not permit any Subsidiary to, 
incur any Debt, other than Intercompany Debt, that is subordinate in 
right of payment to the Notes, if, immediately after giving effect to 
the incurrence of such Debt and the application of the proceeds thereof, 
the aggregate principal amount of all outstanding Debt of the Company 
and its Subsidiaries on a consolidated basis determined in accordance

additional Debt is to be incurred would have been less than 1.5 to 1, on 
a pro forma basis, after giving effect to the incurrence of such Debt 
and to the application of the proceeds thereof.

      (c)  The Company will not, and will not permit any Subsidiary to, 
incur any Debt secured by any mortgage, lien, charge, pledge, 
encumbrance or security interest of any kind upon any of the properties 
of the Company or any Subsidiary ("Secured Debt"), whether owned at the 
date hereof or hereafter acquired, if, immediately after giving effect 
to the incurrence of such Secured Debt and the application of the 
proceeds thereof, the aggregate principal amount of all outstanding 
Secured Debt of the Company and its Subsidiaries on a consolidated basis 
is greater than 40% of the sum of (i) the Company's Adjusted Total 
Assets as of the end of the most recent fiscal quarter prior to the 
incurrence of such additional Debt and (ii) the increase in Adjusted 
Total Assets since the end of such quarter (including any increase 
resulting from the incurrence of additional Debt).

      (d)  The Company will at all time maintain an Unencumbered Total 
Asset Value in an amount not less than 150% of the aggregate principal 
amount of all outstanding unsecured Debt of the Company and its 
Subsidiaries on a consolidated basis.

For purposes of the foregoing provisions regarding the limitation on the 
incurrence of Debt, Debt shall be deemed to be "incurred" by the Company 
or a Subsidiary whenever the Company or such Subsidiary shall create, 
assume, guarantee or otherwise become liable in respect thereof."

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

[REVERSE OF NOTE]

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


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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Liberty Property Limited Partnership, a Pennsylvania limited partnership 
(the "Company," which term includes any successor entity under the 
Indenture hereinafter referred to), for value received, hereby promises 
to pay to                                                                     
, or registered assigns, upon presentation, the principal sum of $             
, on the Stated Maturity Date specified above (or any Redemption Date or 
Repayment Date, each as defined on the reverse hereof) (each such Stated 
Maturity Date, Redemption Date or Repayment Date being hereinafter 
referred to as the "Maturity Date" with respect to the principal 
repayable on such date) and to pay interest thereon, at a rate per annum 
equal to the Initial Interest Rate specified above until the Initial 
Interest Reset Date specified above and thereafter at a rate determined 
in accordance with the provisions specified above and on the reverse 
hereof or in an Addendum hereto with respect to one or more Interest 
Rate Bases specified above until the principal hereof is paid or duly 
made available for payment, and (to the extent that the payment of such 
interest shall be legally enforceable) at the Default Rate per annum 
specified above on any overdue principal, premium and/or interest.  The 
Company will pay interest in arrears on each Interest Payment Date, if 
any, specified above (each, an "Interest Payment Date"), commencing with 
the first Interest Payment Date next succeeding the Original Issue Date 
specified above, and on the Maturity Date; provided, however, that if 
the Original Issue Date occurs between a Record Date (as defined below) 
and the next succeeding Interest Payment Date, interest payments will 
commence on the second Interest Payment Date next succeeding the 
Original Issue Date to the holder of this Note on the Record Date with 
respect to such second Interest Payment Date.

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

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

If any Interest Payment Date other than the Maturity Date would 
otherwise be a day that is not a Business Day, such Interest Payment 
Date shall be postponed to the next succeeding Business Day, except that 
if LIBOR is an applicable Interest Rate Basis and such Business Day 
falls in the next succeeding calendar month, such Interest Payment Date 
shall be the immediately preceding Business Day, and if the Maturity 
Date falls on a day that is not a Business Day, the required payment of 
principal, premium, if any, and/or interest shall be made on the next 
succeeding Business Day, each with the same force and effect as if made 
on the date such payment was due, and no interest shall accrue with 
respect to such payment for the period from and after such Interest 
Payment Date or the Maturity Date, as the case may be, to the date of 
such payment on the next succeeding Business Day.

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

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

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

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

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

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

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

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

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

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

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

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

[REVERSE OF NOTE]

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


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

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

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

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

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

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

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

The interest rate borne by this Note shall be determined as follows:

(i)Unless the Interest Category of this Note is specified on the face 
hereof as a "Floating Rate/Fixed Rate Note" or an "Inverse Floating Rate 
Note" or as having an Addendum attached or having "Other/Additional 
Provisions," in each case relating to different interest rate formula, 
this Note shall be designated as a "Regular Floating Rate Note" and, 
except as set forth below or specified on the face hereof or in an 
Addendum hereto, shall bear interest at the rate determined by reference 
to the applicable Interest Rate Basis or Bases (a) plus or minus the 
Spread, if any, and/or (b) multiplied by the Spread Multiplier, if any, 
in each case as specified on the face hereof.  Commencing on the Initial 
Interest Reset Date, the rate at which interest on this Note shall be 
payable shall be reset as of each Interest Reset Date specified on the 
face hereof; provided, however, that the interest rate in effect for the 
period, if any, from the Original Issue Date to the Initial Interest 
Reset Date shall be the Initial Interest Rate.

(ii)If the Interest Category of this Note is specified on the face 
hereof as a "Floating Rate/Fixed Rate Note," then, except as described 
below or specified on the face hereof or in an Addendum hereto, this 
Note shall bear interest at the rate determined by reference to the 
applicable Interest Rate Basis or Bases (a) plus or minus the Spread, if 
any, and/or (b) multiplied by the Spread Multiplier, if any.  Commencing 
on the Initial Interest Reset Date, the rate at which interest on this 
Note shall be payable shall be reset as of each Interest Reset Date; 
provided, however, that (y) the interest rate in effect for the period, 
if any, from the Original Issue Date to the Initial Interest Reset Date 
shall be the Initial Interest Rate and (z) the interest rate in effect 
for the period commencing on the Fixed Rate Commencement Date specified 
on the face hereof to the Maturity Date shall be the Fixed Interest Rate 
specified on the face hereof or, if no such Fixed Interest Rate is 
specified, the interest rate in effect hereon on the day immediately 
preceding the Fixed Rate Commencement Date.

(iii)If the Interest Category of this Note is specified on the face 
hereof as an "Inverse Floating Rate Note," then, except as set forth 
below or specified on the face hereof or in an Addendum hereto, this 
Note shall bear interest at the Fixed Interest Rate minus the rate 
determined by reference to the applicable Interest Rate Basis or Bases 
(a) plus or minus the Spread, if any, and/or (b) multiplied by the 
Spread Multiplier, if any; provided, however, that, unless otherwise 
specified on the face hereof or in an Addendum hereto, the interest rate 
hereon shall not be less than zero.  Commencing on the Initial Interest 
Reset Date, the rate at which interest on this Note shall be payable 
shall be reset as of each Interest Reset Date; provided, however, that 
the interest rate in effect for the period, if any, from the Original 
Issue Date to the Initial Interest Reset Date shall be the Initial 
Interest Rate.

Except as set forth above or specified on the face hereof or in an 
Addendum hereto, the interest rate in effect on each day shall be (i) if 
such day is an Interest Reset Date, the interest rate determined as of 
the Interest Determination Date (as defined below) immediately preceding 
such Interest Reset Date or (ii) if such day is not an Interest Reset 
Date, the interest rate determined as of the Interest Determination Date 
immediately preceding the most recent Interest Reset Date.  If any 
Interest Reset Date would otherwise be a day that is not a Business Day, 
such Interest Reset Date shall be postponed to the next succeeding 
Business Day, except that if LIBOR is an applicable Interest Rate Basis 
and such Business Day falls in the next succeeding calendar month, such 
Interest Reset Date shall be the immediately preceding Business Day.  In 
addition, if the Treasury Rate is an applicable Interest Rate Basis and 
the Interest Determination Date would otherwise fall on an Interest 
Reset Date, then such Interest Reset Date will be postponed to the next 
succeeding Business Day.

The interest rate applicable to each Interest Reset Period commencing on 
the related Interest Reset Date will be determined by the Calculation 
Agent as of the applicable Interest Determination Date and will be 
calculated by the Calculation Agent on or prior to the Calculation Date 
(as defined below), except with respect to LIBOR and the 11th District 
Cost of Funds Rate, which will be calculated on such Interest 
Determination Date.  The "Interest Determination Date" with respect to 
the CD Rate, the CMT Rate, the Commercial Paper Rate, the Federal Funds 
Rate, the Kenny Rate and the Prime Rate will be the second Business Day 
immediately preceding the applicable Interest Reset Date; the "Interest 
Determination Date" with respect to the 11th District Cost of Funds Rate 
shall be the last working day of the month immediately preceding the 
applicable Interest Reset Date on which the Federal Home Loan Bank of 
San Francisco (the "FHLB of San Francisco") publishes the Index (as 
defined below); and the "Interest Determination Date" with respect to 
LIBOR shall be the second London Business Day immediately preceding the 
applicable Interest Reset Date, unless the Designated LIBOR Currency is 
British pounds sterling, in which case the "Interest Determination Date" 
will be the applicable Interest Reset Date.  The "Interest Determination 
Date" with respect to the Treasury Rate shall be the day in the week in 
which the applicable Interest Reset Date falls on which day Treasury 
Bills (as defined below) are normally auctioned (Treasury Bills are 
normally sold at an auction held on Monday of each week, unless that day 
is a legal holiday, in which case the auction is normally held on the 
following Tuesday, except that such auction may be held on the preceding 
Friday); provided, however, that if an auction is held on the Friday of 
the week preceding the applicable Interest Reset Date, the "Interest 
Determination Date" shall be such preceding Friday, provided, further, 
that if the Interest Determination Date would otherwise fall on an 
Interest Reset Date, then such Interest Reset Date shall be postponed to 
the next succeeding Business Day.  If the interest rate of this Note is 
determined with reference to two or more Interest Rate Bases specified 
on the face hereof, the "Interest Determination Date" pertaining to this 
Note shall be the most recent Business Day which is at least two 
Business Days prior to the applicable Interest Reset Date on which each 
Interest Rate Basis is determinable. Each Interest Rate Basis shall be 
determined as of such date, and the applicable interest rate shall take 
effect on the applicable Interest Reset Date.

Unless otherwise specified on the face hereof or in an Addendum hereto, 
the rate with respect to each Interest Rate Basis will be determined in 
accordance with the following provisions.

CD Rate.  If an Interest Rate Basis for this Note is specified on the 
face hereof as the CD Rate, the CD Rate shall be determined as of the 
applicable Interest Determination Date (a "CD Rate Interest 
Determination Date") as the rate on such date for negotiable United 
States dollar certificates of deposit having the Index Maturity 
specified on the face hereof as published by the Board of Governors of 
the Federal Reserve System in "Statistical Release H.15(519), Selected 
Interest Rates" or any successor publication ("H.15(519)") under the 
heading "CDs (Secondary Market)", or, if not published by 3:00 P.M., New 
York City time, on the related Calculation Date, the rate on such CD 
Rate Interest Determination Date for negotiable United States dollar 
certificates of deposit of the Index Maturity as published by the 
Federal Reserve Bank of New York in its daily statistical release 
"Composite 3:30 P.M. Quotations for United States Government Securities" 
or any successor publication ("Composite Quotations") under the heading 
"Certificates of Deposit".  If such rate is not yet published in either 
H.15(519) or Composite Quotations by 3:00 P.M., New York City time, on 
the related Calculation Date, then the CD Rate on such CD Rate Interest 
Determination Date will be calculated by the Calculation Agent specified 
on the face hereof and will be the arithmetic mean of the secondary 
market offered rates as of 10:00 A.M., New York City time, on such CD 
Rate Interest Determination Date, of three leading nonbank dealers in 
negotiable United States dollar certificates of deposit in The City of 
New York selected by the Calculation Agent for negotiable United States 
dollar certificates of deposit of major United States money center banks 
in the market for negotiable United States dollar certificates of 
deposit with a remaining maturity closest to the Index Maturity in an 
amount that is representative for a single transaction in that market at 
that time; provided, however, that if the dealers so selected by the 
Calculation Agent are not quoting as mentioned in this sentence, the CD 
Rate determined as of such CD Rate Interest Determination Date will be 
the CD Rate in effect on such CD Rate Interest Determination Date.

CMT Rate.  If an Interest Rate Basis for this Note is specified on the 
face hereof as the CMT rate, the CMT Rate shall be determined as of the 
applicable Interest Determination Date (a "CMT Rate Interest 
Determination Date") as the rate displayed on the Designated CMT 
Telerate Page (as defined below) under the caption "...Treasury Constant 
Maturities...Federal Reserve Board Release H.15...Mondays Approximately 
3:45 P.M.," under the column for the Designated CMT Maturity Index (as 
defined below) for (i) if the Designated CMT Telerate Page is 7055, the 
rate on such CMT Rate Interest Determination Date and (ii) if the 
Designated CMT Telerate Page is 7052, the weekly or monthly average, as 
specified on the face hereof, for the week or month, as applicable, 
ended immediately preceding the week or month, as applicable, in which 
the related CMT Rate Interest Determination Date occurs.  If such rate 
is no longer displayed on the relevant page or is not displayed by 3:00 
P.M., New York City time, on the related Calculation Date, then the CMT 
Rate for such CMT Rate Interest Determination Date will be such treasury 
constant maturity rate for the Designated CMT Maturity Index as 
published in H.15(519).  If such rate is no longer published or is not 
published by 3:00 P.M., New York City time, on the related Calculation 
Date, then the CMT Rate on such CMT Rate Interest Determination Date 
will be such treasury constant maturity rate for the Designated CMT 
Maturity Index (or other United States Treasury rate for the Designated 
CMT Maturity Index) for the CMT Rate Interest Determination Date with 
respect to such Interest Reset Date as may then be published by either 
the Board of Governors of the Federal Reserve System or the United 
States Department of the Treasury that the Calculation Agent determines 
to be comparable to the rate formerly displayed on the Designated CMT 
Telerate Page and published in H.15(519).  If such information is not 
provided by 3:00 P.M., New York City time, on the related Calculation 
Date, then the CMT Rate on the CMT Rate Interest Determination Date will 
be calculated by the Calculation Agent and will be a yield to maturity, 
based on the arithmetic mean of the secondary market offered rates as of 
approximately 3:30 P.M., New York City time, on such CMT Rate Interest 
Determination Date reported, according to their written records, by 
three leading primary United States government securities dealers in The 
City of New York (each, a "Reference Dealer") selected by the 
Calculation Agent (from five such Reference Dealers selected by the 
Calculation Agent and eliminating the highest quotation (or, in the 
event of equality, one of the highest) and the lowest quotation (or, in 
the event of equality, one of the lowest)), for the most recently issued 
direct noncallable fixed rate obligations of the United States 
("Treasury Notes") with an original maturity of approximately the 
Designated CMT Maturity Index and a remaining term to maturity of not 
less than such Designated CMT Maturity Index minus one year.  If the 
Calculation Agent is unable to obtain three such Treasury Note 
quotations, the CMT Rate on such CMT Rate Interest Determination Date 
will be calculated by the Calculation Agent and will be a yield to 
maturity based on the arithmetic mean of the secondary market offered 
rates as of approximately 3:30 P.M., New York City time, on such CMT 
Rate Interest Determination Date of three Reference Dealers in The City 
of New York (from five such Reference Dealers selected by the 
Calculation Agent and eliminating the highest quotation (or, in the 
event of equality, one of the highest) and the lowest quotation (or, in 
the event of equality, one of the lowest)), for Treasury Notes with an 
original maturity of the number of years that is the next highest to the 
Designated CMT Maturity Index and a remaining term to maturity closest 
to the Designated CMT Maturity Index and in an amount of at least U.S. 
$100 million.  If three or four (and not five) of such Reference Dealers 
are quoting as described above, then the CMT Rate will be based on the 
arithmetic mean of the offered rates obtained and neither the highest 
nor the lowest of such quotes will be eliminated; provided, however, 
that if fewer than three Reference Dealers selected by the Calculation 
Agent are quoting as mentioned herein, the CMT Rate determined as of 
such CMT Rate Interest Determination Date will be the CMT Rate in effect 
on such CMT Rate Interest Determination Date.  If two Treasury Notes 
with an original maturity as described in the second preceding sentence 
have remaining terms to maturity equally close to the Designated CMT 
Maturity Index, the Calculation Agent will obtain quotations for the 
Treasury Note with the shorter remaining term to maturity and will use 
such quotations to calculate the CMT Rate as set forth above.

"Designated CMT Telerate Page" means the display on the Dow Jones 
Telerate Service (or any successor service) on the page specified on the 
face hereof (or any other page as may replace such page on that service 
(or any successor service) for the purpose of displaying Treasury 
Constant Maturities as reported in H.15(519)).  If no such page is 
specified on the face hereof, the Designated CMT Telerate Page shall be 
7052, for the most recent week.

"Designated CMT Maturity Index" means the original period to maturity of 
the United States Treasury securities (either one, two, three, five, 
seven, 10, 20 or 30 years) specified on the face hereof with respect to 
which the CMT Rate will be calculated.  If no such maturity is specified 
on the face hereof, the Designated CMT Maturity Index shall be two 
years.

Commercial Paper Rate.  If an Interest Rate Basis for this Note is 
specified on the face hereof as the Commercial Paper Rate, the 
Commercial Paper Rate shall be determined as of the applicable Interest 
Determination Date (a "Commercial Paper Rate Interest Determination 
Date") as the Money Market Yield (as defined below) on such date of the 
rate for commercial paper having the Index Maturity as published in 
H.15(519) under the heading "Commercial Paper".  In the event that such 
rate is not published by 3:00 P.M., New York City time, on the related 
Calculation Date, then the Commercial Paper Rate on such Commercial 
Paper Rate Interest Determination Date will be the Money Market Yield of 
the rate for commercial paper having the Index Maturity as published in 
Composite Quotations under the caption "Commercial--Nonfinancial Paper" 
(with an Index Maturity of one month or three months being deemed to be 
equivalent to an Index Maturity of 30 days or 90 days, respectively).  
If such rate is not yet published in either H.15(519) or Composite 
Quotations by 3:00 P.M., New York City time, on such Calculation Date, 
then the Commercial Paper Rate on such Commercial Paper Rate Interest 
Determination Date will be calculated by the Calculation Agent and shall 
be the Money Market Yield of the arithmetic mean of the offered rates at 
approximately 11:00 A.M., New York City time, on such Commercial Paper 
Rate Interest Determination Date of three leading dealers of commercial 
paper in The City of New York selected by the Calculation Agent for 
commercial paper having the Index Maturity placed for an industrial 
issuer whose bond rating is "Aa," or the equivalent, from a nationally 
recognized statistical rating organization; provided, however, that if 
the dealers so selected by the Calculation Agent are not quoting as 
mentioned in this sentence, the Commercial Paper Rate determined as of 
such Commercial Paper Rate Interest Determination Date will be the 
Commercial Paper Rate in effect on such Commercial Paper Rate Interest 
Determination Date.

"Money Market Yield" means a yield (expressed as a percentage) 
calculated in accordance with the following formula:

Money Market Yield = D x 360 
                               --------------------------- x 100
                                        360 - (D x M)

where "D" refers to the applicable per annum rate for commercial paper 
quoted on a bank discount basis and expressed as a decimal, and "M" 
refers to the actual number of days in the applicable Interest Reset 
Period.

11th District Cost of Funds Rate.  If an Interest Rate Basis for this 
Note is specified on the face hereof as the 11th District Cost of Funds 
Rate, the 11th District Cost of Funds Rate shall be determined as of the 
applicable Interest Determination Date (an "11th District Cost of Funds 
Rate Interest Determination Date") as the rate equal to the monthly 
weighted average cost of funds for the calendar month immediately 
preceding the month in which such 11th District Cost of Funds Rate 
Interest Determination Date falls, as set forth under the caption "11th 
District" on Telerate Page 7058 as of 11:00 A.M., San Francisco time, on 
such 11th District Cost of Funds Rate Interest Determination Date.  If 
such rate does not appear on Telerate Page 7058 on such 11th District 
Cost of Funds Rate Interest Determination Date, then the 11th District 
Cost of Funds Rate on such 11th District Cost of Funds Rate Interest 
Determination Date shall be the monthly weighted average cost of funds 
paid by member institutions of the 11th Federal Home Loan Bank District 
that was most recently announced (the "Index") by the FHLB of San 
Francisco as such cost of funds for the calendar month immediately 
preceding such 11th District Cost of Funds Rate Interest Determination 
Date.  If the FHLB of San Francisco fails to announce the Index on or 
prior to such 11th District Cost of Funds Rate Interest Determination 
Date for the calendar month immediately preceding such 11th District 
Cost of Funds Rate Interest Determination Date, the 11th District Cost 
of Funds Rate determined as of such 11th District Cost of Funds Rate 
Interest Determination Date will be the 11th District Cost of Funds Rate 
in effect on such 11th District Cost of Funds Rate Interest 
Determination Date.

Federal Funds Rate.  If an Interest Rate Basis for this Note is 
specified on the face hereof as the Federal Funds Rate, the Federal 
Funds Rate shall be determined as of the applicable Interest 
Determination Date (a "Federal Funds Rate Interest Determination Date") 
as the rate on such date for United States dollar federal funds as 
published in H.15(519) under the heading "Federal Funds (Effective)" or, 
if not published by 3:00 P.M., New York City time, on the Calculation 
Date, the rate on such Federal Funds Rate Interest Determination Date as 
published in Composite Quotations under the heading "Federal 
Funds/Effective Rate."  If such rate is not published in either 
H.15(519) or Composite Quotations by 3:00 P.M., New York City time, on 
the related Calculation Date, then the Federal Funds Rate on such 
Federal Funds Interest Determination Date shall be calculated by the 
Calculation Agent and will be the arithmetic mean of the rates for the 
last transaction in overnight United States dollar federal funds 
arranged by three leading brokers of federal funds transactions in The 
City of New York selected by the Calculation Agent, prior to 9:00 A.M., 
New York City time, on such Federal Funds Rate Interest Determination 
Date; provided, however, that if the brokers so selected by the 
Calculation Agent are not quoting as mentioned in this sentence, the 
Federal Funds Rate determined as of such Federal Funds Rate Interest 
Determination Date will be the Federal Funds Rate in effect on such 
Federal Funds Rate Interest Determination Date.

LIBOR.  If an Interest Rate Basis for this Note is specified on the face 
hereof as LIBOR, LIBOR shall be determined by the Calculation Agent as 
of the applicable Interest Determination Date (a "LIBOR Interest 
Determination Date") in accordance with the following provisions: 

(i) if (a) "LIBOR Reuters" is specified on the face hereof, the 
arithmetic mean of the offered rates (unless the Designated LIBOR Page 
(as defined below) by its terms provides only for a single rate, in 
which case such single rate will be used) for deposits in the Designated 
LIBOR Currency having the Index Maturity, commencing on the applicable 
Interest Reset Date, that appear (or, if only a single rate is required 
as aforesaid, appears) on the Designated LIBOR Page (as defined below) 
as of 11:00 A.M., London time, on such LIBOR Interest Determination 
Date, or (b) "LIBOR Telerate" is specified on the face hereof, or if 
neither "LIBOR Reuters" nor "LIBOR Telerate" is specified on the face 
hereof as the method for calculating LIBOR, the rate for deposits in the 
Designated LIBOR Currency having the Index Maturity, commencing on such 
Interest Reset Date, that appears on the Designated LIBOR Page as of 
11:00 A.M., London time, on such LIBOR Interest Determination Date.  If 
fewer than two such offered rates appear, or if no such rate appears, as 
applicable, LIBOR on such LIBOR Interest Determination Date shall be 
determined in accordance with the provisions described in clause (ii) 
below.

(ii) with respect to a LIBOR Interest Determination Date on which fewer 
than two offered rates appear, or no rate appears, as the case may be, 
on the Designated LIBOR Page as specified in clause (i) above, the 
Calculation Agent shall request the principal London offices of each of 
four major reference banks in the London interbank market, as selected 
by the Calculation Agent, to provide the Calculation Agent with its 
offered quotation for deposits in the Designated LIBOR Currency for the 
period of the Index Maturity, commencing on the applicable Interest 
Reset Date, to prime banks in the London interbank market at 
approximately 11:00 A.M., London time, on such LIBOR Interest 
Determination Date and in a principal amount that is representative for 
a single transaction in the Designated LIBOR Currency in such market at 
such time.  If at least two such quotations are so provided, then LIBOR 
on such LIBOR Interest Determination Date will be the arithmetic mean of 
such quotations.  If fewer than two such quotations are so provided, 
then LIBOR on such LIBOR Interest Determination Date will be the 
arithmetic mean of the rates quoted at approximately 11:00 A.M., in the 
applicable Principal Financial Center, on such LIBOR Interest 
Determination Date by three major banks in such Principal Financial 
Center selected by the Calculation Agent for loans in the Designated 
LIBOR Currency to leading European banks, having the Index Maturity and 
in a principal amount that is representative for a single transaction in 
the Designated LIBOR Currency in such market at such time; provided, 
however, that if the banks so selected by the Calculation Agent are not 
quoting as mentioned in this sentence, LIBOR determined as of such LIBOR 
Interest Determination Date shall be LIBOR in effect on such LIBOR 
Interest Determination Date.

"Designated LIBOR Currency" means the currency or composite currency 
specified on the face hereof as to which LIBOR shall be calculated.  If 
no such currency or composite currency is specified on the face hereof, 
the Designated LIBOR Currency shall be United States dollars.

"Designated LIBOR Page" means (a) if "LIBOR Reuters" is specified on the 
face hereof, the display on the Reuter Monitor Money Rates Service (or 
any successor service) on the page specified on the face hereof (or any 
other page as may replace such page on such service (or any successor 
service)), for the purpose of displaying the London interbank rates of 
major banks for the Designated LIBOR Currency, or (b) if "LIBOR 
Telerate" is specified on the face hereof or if neither "LIBOR Reuters" 
nor "LIBOR Telerate" is specified on the face hereof as the method for 
calculating LIBOR, the display on the Dow Jones Telerate Service (or any 
successor service) on the page specified on the face hereof (or any 
other page as may replace such page on such service (or any successor 
service)), for the purpose of displaying the London interbank rates of 
major banks for the Designated LIBOR Currency.

Kenny Rate.  If an Interest Rate Basis for this Note is specified on the 
face hereof as the Kenny Rate, the Kenny Rate shall be determined as of 
the applicable Interest Determination Date (a "Kenny Rate Interest 
Determination Date") as the rate equal to the high grade weekly index 
(the "Weekly Index") on such date made available by Kenny Information 
Systems ("Kenny") to the Calculation Agent.  The Weekly Index is, and 
shall be, based upon 30 day yield evaluations at par of bonds, the 
interest on which is exempt from Federal income taxation under the 
Internal Revenue Code of 1986, as amended (the "Code"), of not less than 
five high grade component issuers selected by Kenny which shall include, 
without limitation, issuers of general obligation bonds.  The specific 
issuers included among the component issuers may be changed from time to 
time by Kenny in its discretion.  The bonds on which the Weekly Index is 
based shall not include any bonds on which the interest is subject to a 
minimum tax or similar tax under the Code, unless all tax-exempt bonds 
are subject to such tax.  In the event Kenny ceases to make available 
such Weekly Index, a successor indexing agent will be selected by the 
Calculation Agent, such index to reflect the prevailing rate for bonds 
rated in the highest short-term rating category by Moody's Investors 
Service, Inc. and Standard & Poor's Corporation in respect of issuers 
most closely resembling the high grade component issuers selected by 
Kenny for its Weekly Index, the interest on which is (A) variable on a 
weekly basis, (B) exempt from Federal income taxation under the Code, 
and (C) not subject to a minimum tax or similar tax under the Code, 
unless all tax-exempt bonds are subject to such tax.  If such successor 
indexing agent is not available, the rate for any Kenny Rate Interest 
Determination Date shall be 67% of the rate determined if the Treasury 
Rate option had been originally selected.

Prime Rate.  If an Interest Rate Basis for this Note is specified on the 
face hereto as the Prime Rate, the Prime Rate shall be determined as of 
the applicable Interest Determination Date (a "Prime Rate Interest 
Determination Date") as the rate on such date as such rate is published 
in H.15(519) under the heading "Bank Prime Loan."  If such rate is not 
published prior to 3:00 P.M., New York City time, on the related 
Calculation Date, then the Prime Rate shall be the arithmetic mean of 
the rates of interest publicly announced by each bank that appears on 
the Reuters Screen USPRIME1 Page (as defined below) as such bank's prime 
rate or base lending rates as in effect for such Prime Rate Interest 
Determination Date.  If fewer than four such rates appear on the Reuters 
Screen USPRIME1 Page for such Prime Rate Interest Determination Date, 
then the Prime Rate shall be the arithmetic mean of the prime rates 
quoted on the basis of the actual number of days in the year divided by 
a 360-day year as of the close of business on such Prime Rate Interest 
Determination Date by four major money center banks in The City of New 
York selected by the Calculation Agent.  If fewer than four such 
quotations are so provided, the Prime Rate shall be the arithmetic mean 
of four prime rates quoted on the basis of the actual number of days in 
the year divided by a 360-day year as of the close of business on such 
Prime Rate Interest Determination Date as furnished in The City of New 
York by the major money center banks, if any, that have provided such 
quotations and by a reasonable number of substitute banks or trust 
companies to obtain four such prime rate quotations, provided such 
substitute banks or trust companies are organized and doing business 
under the laws of the United States, or any State thereof, each having 
total equity capital of at least U.S. $500 million and being subject to 
supervision or examination by Federal or State authority, selected by 
the Calculation Agent to provide such rate or rates; provided, however, 
that if the banks or trust companies so selected by the Calculation 
Agent are not quoting as mentioned in this sentence, the Prime Rate 
determined as of such Prime Rate Interest Determination Date will be the 
Prime Rate in effect on such Prime Rate Interest Determination Date.

"Reuters Screen USPRIME1 Page" means the display designated as page 
"USPRIME1" on the Reuter Monitor Money Rates Service (or any successor 
service) (or such other page as may replace the USPRIME1 page on such 
service (or any successor service) for the purpose of displaying prime 
rates or base lending rates of major United States banks).

Treasury Rate.  If an Interest Rate Basis for this Note is specified on 
the face hereof as the Treasury Rate, the Treasury Rate shall be 
determined as of the applicable Interest Determination Date (a "Treasury 
Rate Interest Determination Date") as the rate from the auction held on 
such Treasury Rate Interest Determination Date (the "Auction") of direct 
obligations of the United States ("Treasury Bills") having the Index 
Maturity, as such rate is published in H.15(519) under the heading 
"Treasury bills-auction average (investment)" or, if not published by 
3:00 P.M., New York City time, on the related Calculation Date, the 
auction average rate of such Treasury Bills (expressed as a bond 
equivalent on the basis of a year of 365 or 366 days, as applicable, and 
applied on a daily basis) as otherwise announced by the United States 
Department of the Treasury.  In the event that the results of the 
Auction of Treasury Bills having the Index Maturity are not reported as 
provided above by 3:00 P.M., New York City time, on such Calculation 
Date, or if no such Auction is held, then the Treasury Rate shall be 
calculated by the Calculation Agent and shall be a yield to maturity 
(expressed as a bond equivalent on the basis of a year of 365 or 366 
days, as applicable, and applied on a daily basis) of the arithmetic 
mean of the secondary market bid rates, as of approximately 3:30 P.M., 
New York City time, on such Treasury Rate Interest Determination Date, 
of three leading primary United States government securities dealers 
selected by the Calculation Agent, for the issue of Treasury Bills with 
a remaining maturity closest to the Index Maturity; provided, however, 
that if the dealers so selected by the Calculation Agent are not quoting 
as mentioned in this sentence, the Treasury Rate determined as of such 
Treasury Rate Interest Determination Date will be the Treasury Rate in 
effect on such Treasury Rate Interest Determination Date.

Notwithstanding the foregoing, the interest rate hereon shall not be 
greater than the Maximum Interest Rate, if any, or less than the Minimum 
Interest Rate, if any, in each case as specified on the face hereof.  
The interest rate on this Note will in no event be higher than the 
maximum rate permitted by New York law, as the same may be modified by 
United States law of general application.

The Calculation Agent shall calculate the interest rate hereon on or 
before each Calculation Date.  The "Calculation Date", if applicable, 
pertaining to any Interest Determination Date shall be the earlier of 
(i) the tenth calendar day after such Interest Determination Date or, if 
such day is not a Business Day, the next succeeding Business Day or (ii) 
the Business Day immediately preceding the applicable Interest Payment 
Date or the Maturity Date, as the case may be.  At the request of the 
holder hereof, the Calculation Agent will provide to the holder hereof 
the interest rate hereon then in effect and, if determined, the interest 
rate that will become effective as a result of a determination made for 
the next succeeding Interest Reset Date.

Accrued interest hereon shall be an amount calculated by multiplying the 
principal amount hereof by an accrued interest factor.  Such accrued 
interest factor shall be computed by adding the interest factor 
calculated for each day in the applicable Interest Period.  Unless 
otherwise specified as the Day Count Convention on the face hereof, the 
interest factor for each such date shall be computed by dividing the 
interest rate applicable to such day by 360 if the CD Rate, the 
Commercial Paper Rate, the 11th District Cost of Funds Rate, the Federal 
Funds Rate, LIBOR or the Prime Rate is an applicable Interest Rate Basis 
or by the actual number of days in the year if the CMT Rate or the 
Treasury Rate is an applicable Interest Rate Basis, or by 365 if Kenny 
Rate is an applicable Interest Rate Basis.  Unless otherwise specified 
as the Day Count Convention on the face hereof, the interest factor for 
this Note, if the interest rate is calculated with reference to two or 
more Interest Rate Bases, shall be calculated in each period in the same 
manner as if only the Applicable Interest Rate Basis specified on the 
face hereof applied.

All percentages resulting from any calculation on this Note shall be 
rounded to the nearest one hundred-thousandth of a percentage point, 
with five one-millionths of a percentage point rounded upwards, and all 
amounts used in or resulting from such calculation on this Note shall be 
rounded, in the case of United States dollars, to the nearest cent or, 
in the case of a Specified Currency other than United States dollars, to 
the nearest unit (with one-half cent or unit being rounded upwards).

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

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

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

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

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

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

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

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

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

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

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

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

Liberty Property Limited Partnership, a Pennsylvania limited partnership 
(the "Company," which term includes any successor entity under the 
Indenture hereinafter referred to), for value received, hereby promises 
to pay to CEDE & CO, or registered assigns, upon presentation, the 
principal sum of $75,000,000  (Seventy Five Million), on the Stated 
Maturity Date specified above (or any Redemption Date or Repayment Date, 
each as defined on the reverse hereof) (each such Stated Maturity Date, 
Redemption Date or Repayment Date being hereinafter referred to as the 
"Maturity Date" with respect to the principal repayable on such date) 
and to pay interest thereon, at the Interest Rate per annum specified 
above, until the principal hereof is paid or duly made available for 
payment, and (to the extent that the payment of such interest shall be 
legally enforceable) at the Default Rate per annum specified above on 
any overdue principal, premium and/or interest.  The Company will pay 
interest in arrears on each Interest Payment Date, if any, specified 
above (each, an "Interest Payment Date"), commencing with the first 
Interest Payment Date next succeeding the Original Issue Date specified 
above, and on the Maturity Date; provided, however, that if the Original 
Issue Date occurs between a Record Date (as defined below) and the next 
succeeding Interest Payment Date, interest payments will commence on the 
second Interest Payment Date next succeeding the Original Issue Date to 
the holder of this Note on the Record Date with respect to such second 
Interest Payment Date.  Interest on this Note will be computed on the 
basis of a 360-day year of twelve 30-day months.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                              [REVERSE OF NOTE]

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


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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Liberty Property Limited Partnership, a Pennsylvania limited partnership 
(the "Company," which term includes any successor entity under the 
Indenture hereinafter referred to), for value received, hereby promises 
to pay to    CEDE & CO, or registered assigns, upon presentation, the 
principal sum of $100,000,000 (One Hundred Million), on the Stated 
Maturity Date specified above (or any Redemption Date or Repayment Date, 
each as defined on the reverse hereof) (each such Stated Maturity Date, 
Redemption Date or Repayment Date being hereinafter referred to as the 
"Maturity Date" with respect to the principal repayable on such date) 
and to pay interest thereon, at the Interest Rate per annum specified 
above, until the principal hereof is paid or duly made available for 
payment, and (to the extent that the payment of such interest shall be 
legally enforceable) at the Default Rate per annum specified above on 
any overdue principal, premium and/or interest.  The Company will pay 
interest in arrears on each Interest Payment Date, if any, specified 
above (each, an "Interest Payment Date"), commencing with the first 
Interest Payment Date next succeeding the Original Issue Date specified 
above, and on the Maturity Date; provided, however, that if the Original 
Issue Date occurs between a Record Date (as defined below) and the next 
succeeding Interest Payment Date, interest payments will commence on the 
second Interest Payment Date next succeeding the Original Issue Date to 
the holder of this Note on the Record Date with respect to such second 
Interest Payment Date.  Interest on this Note will be computed on the 
basis of a 360-day year of twelve 30-day months.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

IN WITNESS WHEREOF, Liberty Property Limited Partnership has caused this

TRUSTEE'S CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated therein referred 
to in the within-mentioned Indenture.


THE FIRST NATIONAL BANK OF CHICAGO,
     as Trustee




By       /s/ Mark J. Frye                    Date:   Oct. 24, 1997

Authorized Signatory




                                  [REVERSE OF NOTE]

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


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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

      2.   Letters of Credit.   Section 2 of the Restated Agreement is 
hereby amended by adding a new Section 2.9 at the end thereof:

          Section 2.9.   LETTERS OF CREDIT

                         (a)  Up to $30,000,000 of the Commitments may 
be used by Borrower for the issuance of Letters of Credit by the Agent 
for the account of the Borrower subject to the terms and conditions set 
forth herein.  Each Letter of Credit shall be denominated in dollars and 
shall be a standby letter of credit issued to support the obligations of 
Borrower in connection with any purposes for which the proceeds of the 
Loans may be used pursuant to Section7.11.  The issuance of a Letter of 
Credit shall be deemed to be an Investment under Section8.2(g) as of the 
time of issuance.  Each Letter of Credit shall have an initial term of 
not more than one (1) year, and shall expire no later than five (5) 
Business Days prior to the Maturity Date.  Although the Agent shall be 
the issuing bank of the Letter of Credit, each Bank hereby accepts for 
its own account and risk an undivided interest equal to its Commitment 
Percentage in the Agent's obligations and rights under each Letter of 
Credit issued hereunder.  Each Bank unconditionally and irrevocably 
agrees with the Agent that, if a draft is paid under any Letter of 
Credit, such Bank shall promptly pay to the Agent  an amount equal to 
such Bank's Commitment Percentage of the amount of such draft or any 
part thereof.   Upon the issuance of each Letter of Credit hereunder, 
there shall be reserved from each Bank's Commitment an amount equal to 
such Bank's Commitment Percentage of the face amount of the Letter of 
Credit.  Such reserved amounts shall remain in place and shall be 
unavailable for borrowing under Section2.1 until the date that the 
Letter of Credit expires, is fully drawn or is terminated. 

                         (b)  The Borrower shall give to the Agent a 
written notice in the form of Exhibit F hereto of each Letter of Credit 
requested hereunder (a "Letter of Credit Request") no less than five (5) 
Business Days prior to the proposed issuance date of the requested 
Letter of Credit.  Each Letter of Credit Request shall specify (i) the 
name and address of the beneficiary of the requested Letter of Credit, 
(ii) the face amount of the requested Letter of Credit, (iii) the 
proposed issuance date and expiration date of the requested Letter of 
Credit, (iv)  the proposed form of the requested Letter of Credit, and 
(v) the permitted purpose for which the Letter of Credit will be used, 
and shall be accompanied by a Compliance Certificate 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 Section 9 hereof after including in the outstanding amount 
of Loans the face amount of the requested Letter of Credit.  The Agent 
may also require that the Borrower complete its standard letter of 
credit application in the form of Exhibit G attached hereto, as such 
standard form may be revised from time to time, and submit the same 
together with the Letter of Credit Request.  Within two (2) Business 
Days after receipt of a Letter of Credit Request, the Agent shall 
provide to each of the Banks by facsimile a copy of such Letter of 
Credit Request and accompanying Compliance Certificate and each Bank 
shall, within 24 hours thereafter, notify the Agent if it believes that 
any of the conditions contained in Section11 of this Agreement has not 
been met or waived such that a Loan in an amount equal to the face 
amount of the requested Letter of Credit could be made on the proposed 
issuance date of such Letter of Credit.  If such a notice is given the 
Requisite Banks shall promptly determine whether all of the conditions 
contained in Section11 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 Section11 
have been met or waived, and if the Agent determines, in its discretion, 
that it is willing to issue the requested Letter of Credit, and that it 
is satisfied with the proposed form thereof, the Letter of Credit shall 
be issued by the Agent and each of the Banks shall then be obligated to 
the Agent with respect to its Commitment Percentage of the Letter of 
Credit as provided above in Section 2.9(a).  

                         (c)  On or before the issuance date of any 
requested Letters of Credit, the Borrower shall pay to the Agent for its 
own account an issuance fee equal to one-eighth percent (.125%) of the 
face amount of the Letter of Credit.  On or before the date of any 
renewal or extension of a Letter of Credit, the Borrower shall pay to 
the Agent for its own account a renewal fee equal to five-hundredths 
percent (.05%) of the face amount of the Letter of Credit.  The Borrower 
shall pay to the Agent for the account of the Banks a Letter of Credit 
fee equal to the then prevailing Applicable Margin per annum of the face 
amount of the Letter of Credit, which  Letter of Credit fee shall be due 
and payable on the issuance date of the Letter of Credit and on the date 
of each renewal or extension thereof, and shall be prorated for any 
partial year based on a 360-day year and paid for the actual number of 
days between the issuance date and the expiration date of such Letter of 
Credit.  Promptly after its receipt thereof the Agent shall distribute 
such Letter of Credit fee to the Banks pro-rata in accordance with their 
respective Commitment Percentages.  Such fees shall be nonrefundable and 
shall not be further prorated in the event that the Letter of Credit 
terminates prior to its scheduled expiration date.  The Borrower also 
agrees to reimburse the Agent for all reasonable fees, costs, expenses 
and disbursements of the Agent in issuing, effecting payment under, 
amending or otherwise administering any Letter of Credit. 

                         (d)  Promptly after each Drawing Date the Agent 
shall notify the Banks and the Borrower of the amount of the draft paid 
by the Agent on such Drawing Date.  The payment of a draft under a 
Letter of Credit shall constitute an advance of a Loan which shall bear 
interest as a Base Rate Loan from the Drawing Date.  On the Drawing Date 
each Bank shall pay to the Agent its Commitment Percentage of the amount 
of the draft under the Letter of Credit so paid.  If the Agent receives 
such payment from any Bank on a date after the Drawing Date, such Bank 
shall pay to the Agent on demand an amount computed in the same manner 
as the amount due to the Agent from a Bank which has made available 
funds for loans after the Drawdown Date thereof pursuant to Section 
2.7(b).  Each Bank's obligation to pay its Commitment Percentage of each 
draft under a Letter of Credit shall not be subject to the satisfaction 
of the conditions set forth in Section11.   Within three (3) Business 
Days after each Drawing Date, the Borrower  shall deliver to the Agent a 
written explanation of the facts and circumstances relating to such 
drawing and a Compliance Certificate and any other information requested 
by the Agent for the purpose of allowing the Banks to determine whether 
the drawing or related events have resulted in a Default or Event of 
Default.  The Agent shall promptly provide copies of such explanation 
and information to the Banks.

                         (e)  The Borrower's obligations under this 
Section 2.9 shall be absolute and unconditional under any and all 
circumstances and irrespective of any set-off, counterclaim or defense 
to payment which the Borrower may have or have had against the Agent, 
any Bank or any beneficiary of a Letter of Credit.  The Borrower also 
agrees that the Agent shall not be responsible for, and the Borrower's 
reimbursement obligations hereunder shall not be affected by, among 
other things, (i) the validity or genuineness of documents or of any 
endorsements thereon, even though such documents shall in fact prove to 
be invalid, fraudulent or forged, or (ii) any dispute between or among 
the Borrower and any beneficiary of any Letter of Credit or any other 
party to which such Letter of Credit may be transferred or (iii) any 
claims whatsoever of the Borrower against any beneficiary of such Letter 
of Credit or any such transferee.  The Agent shall not be liable for any 
error, omission, interruption or delay in transmission, dispatch or 
delivery of any message or advice, however transmitted, in connection 
with any Letter of Credit, except for errors, omissions, interruptions 
or delays caused by the Agent's gross negligence or willful misconduct.  
The Borrower agrees that any action taken or omitted by the Agent under 
or in connection with any Letter of Credit or the related drafts or 
documents, if done in the absence of gross negligence or willful 
misconduct and in accordance with the standards of care specified in the 
Uniform Customs and Practices for Documentary Credits as the same may be 
amended from time to time, shall be binding on the Borrower and shall 
not result in any liability of the Agent to the Borrower.

                         (f)  In the event that any Letters of Credit 
are in effect at the time of an acceleration of the maturity of the 
Loans pursuant to Section 12.1, the amounts which shall thereupon become 
immediately due and payable by the Borrower shall include a sum equal to 
the aggregate face amount of such then effective Letters of Credit.  
Such sum shall be deposited in a cash collateral account to be opened by 
the Agent.  Amounts held in such cash collateral account shall be 
applied by the Agent on each Drawing Date thereafter to pay any drafts 
presented pursuant to the Letters of Credit.  After all Letters of 
Credit have been fully drawn upon, expired or otherwise terminated, any 
balance remaining in such cash collateral account shall be applied in 
the same manner as enforcement proceeds under Section12.4.

      3.   Amendment to Section 8.1.  Section 8.1 of the Restated 
Agreement is hereby amended and restated in its entirety as follows:

                         Section 8.1  Restrictions on Recourse 
Indebtedness.  Except with the prior written consent of the Requisite 
Banks, the Borrower will not, and the Borrower will not permit any 
Guarantor, any of the Related Companies or any Permitted Joint Venture 
to create, incur, assume, guarantee or become or remain liable, 
contingently or otherwise, or agree not to do any of same with respect 
to any Recourse Indebtedness other than:

                         (a)  Indebtedness to the Banks arising under 
any of the Loan Documents;

                         (b)  current liabilities of the Borrower 
incurred in the ordinary course of business but not incurred through (i) 
the borrowing of money, or (ii) the obtaining of credit except for 
credit on an open account basis customarily extended and in fact 
extended in connection with normal purchases of goods and services;

                         (c)  Indebtedness in respect of taxes, 
assessments, governmental charges or levies and claims for labor, 
materials and supplies to the extent that payment therefor shall not at 
the time be required to be made in accordance with the provisions of 
Section7.8;

                         (d)  Indebtedness in respect of judgments or 
awards that have been in force for less than the applicable period for 
taking an appeal so long as execution is not levied thereunder or in 
respect of which the Borrower shall at the time in good faith be 
prosecuting an appeal or proceedings for review and in respect of which 
a stay of execution shall have been obtained pending such appeal or 
review;

                         (e)  endorsements for collection, deposit or 
negotiation and warranties of products or services, in each case 
incurred in the ordinary course of business;

                         (f) Indebtedness presently outstanding under 
the Subordinated Debenture Indenture consisting of the Subordinated 
Debentures in the aggregate amount of approximately $150,244,000 as of 
March 31, 1997;

                         (g)  Indebtedness under unsecured term notes 
which may be hereafter issued by Borrower provided that the weighted 
average maturity date of all such term notes outstanding at any time 
shall not be earlier than four (4) years after the Facility Closing 
Date.  If more than one issue or series of such unsecured term notes is 
outstanding at any time, the foregoing weighted average maturity date 
shall be computed on an aggregate basis including all issues or series 
of such notes;

                         (h)  Recourse Indebtedness other than that 
described in other paragraphs of this Section 8.1 up to a maximum 
principal amount outstanding at any time equal to four percent (4%) of 
Total Assets at such time. 

      4.  Amendment to Section 12.4.  Section 12.4 of the Restated 
Agreement is hereby amended by amending and restating paragraph (c) 
thereof as follows:

                         (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 the deposit 
in any cash collateral account established pursuant to Section2.9(f) of 
the amount required thereby, to the payment of any obligations required 
to be paid pursuant to Section9-504(1)(c) of the Uniform Commercial Code 
of the Commonwealth of Massachusetts; and

      5.  Replacement Exhibit C.  Exhibit C attached to the Restated 
Agreement is hereby replaced with Exhibit C attached hereto.

      6.  Replacement Schedule 1.2.  The Borrower did not exercise its 
Commitment Reduction Option.  Therefore, Schedule 1.2 and the Banks' 
signature pages have been revised to remove the distinction between Core 
Commitments and Additional Commitments.  Schedule 1.2 to the Restated 
Agreement is hereby replaced with Schedule 1.2 attached hereto.

      7.  Replacement Schedule 1.3.  Schedule 1.3 to the Restated 
Agreement is hereby replaced with Schedule 1.3 attached hereto.

represent and warrant that each of the representations and warranties 
contained in Section6 is true, correct and complete in all material 
respects as of the date hereof to the same extent as though made on such 
date and that no Default or Event of Default has occurred and is 
continuing on the date hereof.  

      9.  Miscellaneous.  This Amendment shall be governed by, 
interpreted and construed in accordance with all of the same provisions 
applicable under the Restated Agreement including, without limitation, 
all definitions set forth in Section 1.1, the rules of interpretation 
set forth in Section 1.2, the provisions relating to governing law set 
forth in Section 20, the provisions relating to counterparts in Section 
22 and the provision relating to severability in Section 26.   Except as 
amended hereby all of the terms and conditions set forth in the Restated 
Agreement shall remain in full force and effect and are hereby ratified 
and confirmed.

Amendment as a sealed instrument as of the date first set forth above.

Liberty Property Limited Partnership

Malvern, PA 19355

Compliance Certificate under
Amended and Restated Loan Agreement dated as of June 16, 1997

The undersigned, a Responsible Officer of Liberty Property Trust, 
general partner of Liberty Property Limited Partnership (the 
"Borrower"), hereby certifies on behalf of the Borrower as of the date 
hereof the following:

1.  No Defaults.  I have read a copy of the Amended and Restated Loan 
Agreement dated as of June 16, 1997 (the "Loan Agreement") among the 
Borrower, Liberty Property Trust, BankBoston, N.A., the other lending 
institutions party thereto, and BankBoston, N.A., as Agent. Terms used 
herein and not otherwise defined herein shall have the meanings set 
forth in Section1.1 of the Loan Agreement. No Default is continuing in 
the performance or observance of any of the covenants, terms or 
provisions of the Loan Agreement or any of the other Loan Documents.  
Without limiting the foregoing, the Borrower has not taken any actions 
which are prohibited by the negative covenants set forth in Section8 of 
the Loan Agreement.  Attached hereto as Appendix I are all relevant 
calculations needed to determine whether the Borrower is in compliance 
with Section9.1 through Section9.10, inclusive, Section8.1(h), 
Section8.2(e)(iv) and Section8.2(g) of the Loan Agreement as of the end 
of the most recently completed fiscal quarter (except that in the case 
of Compliance Certificates delivered pursuant to Section2.5(a), 
Section2.9(a), Section11.1 or Section7.13, the calculations determining 
compliance with Section9.1, Section9.2 and Section9.3 are based on 
amounts of Unsecured Indebtedness,  Pro Forma Principal Amount and Total 
Liabilities which have been computed on a pro forma basis after giving 
effect to the proposed transaction and, at the option of Borrower, Value 
of All Unencumbered Properties, Unencumbered Net Operating Income and 
Total Assets may similarly be computed on a proforma basis) and is in 
compliance with Section8.7 of the Loan Agreement for the most recently 
completed fiscal year and over the three most recently completed fiscal 
quarters.

2.  No Material Changes, Etc.  Except as disclosed on Appendix II 
hereto, since the [date of most recent financial statements furnished to 
the Agent and the Banks], there have occurred no materially adverse 
changes in the financial condition or business of the Borrower as shown 
on or reflected in the balance sheet of the Borrower as at such date 
other than (a) changes in the ordinary course of business that have not 
had any materially adverse effect either individually or in the 
aggregate on the business or financial condition of the Borrower and (b) 
changes resulting from the making of the Loans and the transactions 
contemplated by the Loan Agreement.

3.  No Materially Adverse Contracts, Etc.  Neither the Borrower nor the 
Company is subject to any charter, corporate, trust, partnership or 
other legal restriction, or any judgment, decree, order, rule or 
regulation that has or is expected, in the reasonable judgment of the 
Company's officers, in the future to have a Materially Adverse Effect. 
Neither the Borrower nor the Company is  a party to any contract or 
agreement that has or is expected, in the reasonable judgment of the 
Company's officers, to have a Materially Adverse Effect.

4. [Include for Compliance Certificates delivered pursuant to 
Section7.4(d) and Section7.13].  Attached hereto as Appendix III is a 
list of the Unencumbered Properties as of ____________.  The Borrower 
certifies that each of the Real Estate Assets listed on Appendix III 
satisfied on said date each of the conditions set forth in the 
definition of Unencumbered Property, except to the extent that waivers 
may have been granted pursuant to Section5.2.  Appendix III lists for 
each Unencumbered Property its street address, name of the owner, type 
(office or industrial), number of square feet and number of leased 
square feet.
