     WHEREAS, the Company executed and delivered its Indenture (the
"Original Indenture"), dated as of October 24, 1997, to the Trustee to
issue from time to time for its lawful purposes debt securities
evidencing its unsecured indebtedness.

     WHEREAS, the Original Indenture provides that by means of a
supplemental indenture, the Company may create one or more series of
its debt securities and establish the form and terms and conditions
thereof.

     WHEREAS, the Company intends by this Fourth Supplemental Indenture

Limited Partnership 8.50% Senior Notes due 2010" (the "Notes"); and

     WHEREAS, the Board of Trustees of Liberty Property Trust (the

of the Notes and the form, terms and conditions thereof.

     WHEREAS, the consent of Holders to the execution and delivery of
this Fourth Supplemental Indenture is not required, and all other
actions required to be taken under the Original Indenture with respect
to this Fourth Supplemental Indenture have been taken.

     NOW, THEREFORE IT IS AGREED:

                                ARTICLE ONE

     Definitions, Creation, Form and Terms and Conditions of the Debt
     Securities

     SECTION 1.01  Definitions.  Capitalized terms used in this Fourth
Supplemental Indenture and not otherwise defined shall have the
meanings ascribed to them in the Original Indenture.  In addition, the
following terms shall have the following meanings to be equally
applicable to both the singular and the plural forms of the terms
defined:

          "Closing Date" means July 31, 2000.

          "Global Note" means a single fully-registered global note in
book entry form, without coupons, substantially in the form of Exhibit
A attached hereto.

          "Indenture" means the Original Indenture as supplemented by
this Fourth Supplemental Indenture.

          "Intercompany Debt" means Debt to which the only parties are
the Trust, any of its subsidiaries, the Company and any Subsidiary, or
Debt owed to the Trust arising from routine cash management practices,
but only so long as such Debt is held solely by any of the Trust, any
of its subsidiaries, the Company and any Subsidiary.

          "Subsidiary" shall have the meaning provided in the Original
Indenture and shall include Liberty Property Development Corp.-II and
Liberty Property Development Corp. III.

     SECTION 1.02  Creation of the Debt Securities.  In accordance with
Section 301 of the Original Indenture, the Company hereby creates the
Notes as a separate series of its debt securities issued pursuant to
the Indenture.  The Notes shall be issued in an aggregate principal
amount initially limited to $200,000,000.

     The Company may issue, in addition to the Notes originally issued
on the Closing Date, additional Notes.  The Notes originally issued on
the Closing Date and any additional Notes originally issued subsequent
to the Closing Date shall be a single series for all purposes under the
Indenture.

     SECTION 1.03  Form of the Debt Securities.  The Notes will be
represented by one or more fully-registered global notes in book-entry
form, without coupons, registered in the name of the nominee of DTC.
The Notes shall be in the form of Exhibit A attached hereto.  So long
as DTC, or its nominee, is the registered owner of a Global Note, DTC
or its nominee, as the case may be, will be considered the sole owner
or holder of the Notes represented by such Global Note for all purposes
under the Indenture.  Ownership of beneficial interests in the Global
Note will be shown on, and transfers thereof will be effected only
through, records maintained by DTC (with respect to beneficial
interests of participants) or by participants or persons that hold
interests through participants (with respect to beneficial interests of
beneficial owners).

     SECTION 1.04  Terms and Conditions of the Debt Securities.  The
Notes shall be governed by all the terms and conditions of the Original
Indenture, as supplemented by this Fourth Supplemental Indenture, and
in particular, the following provisions shall be the terms of the
Notes:

     (a)  Optional Redemption.  The Issuer may redeem the Notes at any
time at the option of the Issuer, in whole or from time to time in
part, at a redemption price equal to the Redemption Price.
If notice of redemption has been given as provided in the Indenture and
funds for the redemption of any Notes called for redemption shall have
been made available on the Redemption Date referred to in such notice,
such Notes will cease to bear interest on the date fixed for such
redemption specified in such notice and the only right of the Holders
of such Notes from and after the Redemption Date will be to receive
payment of the Redemption Price upon surrender of such Notes in
accordance with such notice.

     Notice of any optional redemption of any Notes will be given to
Holders at their addresses, as shown in the security register for the
Notes, not more than 60 nor less than 30 days prior to the date fixed
for redemption.  The notice of redemption will specify, among other
items, the Redemption Price and the principal amount of the Notes held
by such Holder to be redeemed.

     If all or less than all of the Notes are to be redeemed at the
option of the Issuer, the Issuer will notify the Trustee at least 45
days prior to giving notice of redemption (or such shorter period as is
satisfactory to the Trustee) of the aggregate principal amount of Notes
to be redeemed, if less than all of the Notes are to be redeemed, and
their Redemption Date.  The Trustee shall select, in such manner as it
shall deem fair and appropriate, no less than 60 days prior to the date
of redemption, the Notes to be redeemed in whole or in part.

     (b)  Payment of Principal and Interest.  Principal and interest
payments on interests represented by a Global Note will be made to DTC
or its nominee, as the case may be, as the registered owner of such
Global Note.  All payments of principal and interest in respect of the
Notes will be made by the Issuer in immediately available funds.


     (c)  Applicability of Defeasance or Covenant Defeasance.  The
provisions of Article 14 of the Original Indenture shall apply to the
Notes.

                                 ARTICLE TWO
                             Additional Covenants

     The Notes shall be governed by all the covenants contained in the
Original Indenture, as supplemented by this Fourth Supplemental
Indenture, and in particular, this Fourth Supplemental Indenture amends
Section 1004 of the Original Indenture to read as follows:

     "SECTION 1004.  Limitations on Incurrence of Debt.

     (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 with GAAP is greater than 60% 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).

     (b)  The Company will not, and will not permit any Subsidiary to,
incur any Debt if the ratio of Consolidated Income Available for Debt
Service to the Annual Service Charge on the date on which such
additional Debt is to be incurred, on a pro forma basis, after giving
effect to the incurrence of such Debt and to the application of the
proceeds thereof would have been less than 1.5 to 1.

     (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."

                             ARTICLE THREE

                      [      ]% Senior Notes due [       ]

Liberty Property Limited Partnership, a Pennsylvania limited
partnership (the "Issuer," which term includes any successor under the
Indenture hereinafter referred to), for value received, hereby promises
to pay to Cede & Co. or its registered assigns, the principal sum of
[           ] Dollars on [       ] (the "Maturity Date"), and to pay
interest thereon from [              ] (or from the most recent
interest payment date to which interest has been paid or duly provided
for), semi-annually in arrears on [            ] and [      ]
of each year (each, an "Interest Payment Date"), commencing on [     ],
and on the Maturity Date, at the rate of [       ]% per annum, until
payment of said principal sum has been made or duly provided for.

The interest so payable and punctually paid or duly provided for on any
Interest Payment Date and on the Maturity Date will be paid to the
Holder in whose name this Note (or one or more predecessor Notes) is
registered at the close of business on the "Record Date" for such
payment, which will be 15 days (regardless of whether such day is a
Business Day (as defined below)) prior to such payment date or the
Maturity Date, as the case may be.  Any interest not so punctually paid
or duly provided for shall forthwith cease to be payable to the Holder
on such record date, and shall be paid to the Holder in whose name this
Note (or one or more predecessor Notes) is registered at the close of
business on a subsequent record date for the payment of such defaulted
interest (which shall be not more than 15 days and not less than
10 days prior to the date of the payment of such defaulted interest)
established by notice given by mail by or on behalf of the Issuer to
the Holders of the Notes not less than 10 days preceding such
subsequent record date. Interest on this Note will be computed on the
basis of a 360-day year of twelve 30-day months.

The principal of this Note payable on the Maturity Date will be paid
against presentation and surrender of this Note at the corporate trust
office of the Trustee at One Bank One Plaza, Chicago, Illinois 60670-
0126, in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public or private
debt.

Interest payable on this Note on any Interest Payment Date and on the
Maturity Date, as the case may be, will be the amount of interest
accrued from and including the immediately preceding Interest Payment
Date (or from and including [             ], in the case of the initial
Interest Payment Date) to but excluding the applicable Interest Payment
Date or the Maturity Date, as the case may be.  If any Interest Payment
Date or the Maturity Date falls on a day that is not a Business Day (as
defined below), the required payment of interest or principal or both,
as the case may be, will be made on the next Business Day with the same
force and effect as if it were made on the date such payment was due
and no interest will accrue on the amount so payable for the period
from and after such Interest Payment Date or the Maturity Date, as the
case may be.  "Business Day" means any day, other than a Saturday or a
Sunday, that is neither a legal holiday nor a day on which banking
institutions in The City of New York or Chicago are authorized or
required by law, regulation or executive order to close.

Payments of principal and interest in respect of this Note will be made
by wire transfer of immediately available funds in such coin or
currency of the United States of America as at the time of payment is
legal tender for the payment of public and private debts.

Reference is made to the further provisions of this Note set forth on
the reverse hereof.  Such further provisions shall for all purposes
have the same effect as though fully set forth at this place.

This Note shall not be entitled to the benefits of the Indenture
referred to on the reverse hereof or be valid or become obligatory for
any purpose until the certificate of authentication hereon shall have
been signed by the Trustee under such Indenture.


IN WITNESS WHEREOF, the Issuer has caused this instrument to be signed

evidenced as provided in the Indenture, to execute supplemental
indentures adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of any
supplemental indenture or modifying in any manner the rights of the
Holders of the Securities of each series; provided, however, that no
such supplemental indenture shall, without the consent of the Holder of
each Security so affected, (i) change the Stated Maturity of the
principal of (or premium or Make-Whole Amount, if any, on) or any
installment of interest on, any such Security, (ii) reduce the
principal amount of, or the rate or amount of interest on, or any
premium payable on redemption of the Notes, or adversely affect any
right of repayment of the Holder of any Securities; (iii) change the
place of payment, or the coin or currency, for payment of principal or
premium, if any, or interest on the Securities; (iv) impair the right
to institute suit for the enforcement of any payment on or with respect
to the Securities on or after the stated maturity of any such Security;
(v) reduce the above-stated percentage in principal amount of
outstanding Securities, the extent of whose Holders is necessary to
modify or amend the Indenture, for any waiver with respect to the
Securities or to waive compliance with certain provisions of the
Indenture or certain defaults and consequences thereunder or to reduce
the quorum or voting requirements set forth in the Indenture; or (vi)
modify any of the foregoing provisions or any of the provisions
relating to the waiver of certain past defaults or certain covenants,
except to increase the required percentage to effect such action or to
provide that certain other provisions of the Indenture may not be
modified or waived without the consent of the Holder of each Security.
It is also provided in the Indenture that, with respect to certain
defaults or Events of Default regarding the Securities of any series,
the Holders of a majority in aggregate principal amount outstanding of
the Securities of such series (or, in the case of certain defaults or
Events of Default, all series of Securities) may on behalf of the
Holders of all the Securities of such series (or all of the Securities,
as the case may be) waive any such past default or Event of Default and
its consequences, prior to any declaration accelerating the maturity of
such Securities, or, subject to certain conditions, may rescind a
declaration of acceleration and its consequences with respect to such
Securities. Any such consent or waiver by the Holder of this Security
(unless revoked as provided in the Indenture) shall be conclusive and
binding upon such Holder and upon all future Holders and owners of this
Security and any Securities that may be issued in exchange or
substitution herefor, irrespective of whether or not any notation
thereof is made upon this security or such other securities.

No reference herein to the Indenture and no provision of this security
or of the Indenture shall alter or impair the obligation of the Issuer,
which is absolute and unconditional, to pay the principal of and any
Make-Whole Amount and interest on this security in the manner, at the
respective times, at the rate and in the coin or currency herein
prescribed.

This security is issuable only in registered form without coupons in
denominations of $1,000 and integral multiples thereof.  Securities may
be exchanged for a like aggregate principal amount of securities of
this series of other authorized denominations at the office or agency
of the Issuer in The Borough of Manhattan,  The City of New York, in
the manner and subject to the limitations provided in the Indenture,
but without the payment of any service charge except for any tax or
other governmental charge imposed in connection therewith.

Upon due presentment for registration of transfer of Securities at the
office or agency of the Issuer in The Borough of Manhattan, The City of
New York, one or more new Securities of the same series of authorized
denominations in an equal aggregate principal amount will be issued to
the transferee in exchange therefor, subject to the limitations
provided in the Indenture, without charge except for any tax or other
governmental charge imposed in connection therewith.

The Issuer, the Trustee or any authorized agent of the Issuer or the
Trustee may deem and treat the Person in whose name this security is
registered as the absolute owner of this security (whether or not this
security shall be overdue and notwithstanding any notation of ownership
or other writing hereon), for the purpose of receiving payment of, or
on account of, the principal hereof and Make-Whole Amount, if any, and
subject to the provisions on the face hereof, interest hereon, and for
all other purposes, and neither the Issuer nor the Trustee nor any
authorized agent of the Issuer or the Trustee shall be affected by any
notice to the contrary.

The Indenture and each Security shall be deemed to be a contract under
the laws of the State of New York, and for all purposes shall be
construed in accordance with the laws of such state, except as may
otherwise be required by mandatory provisions of law.

Capitalized terms used herein which are not otherwise defined shall
have the respective meanings assigned to them in the Indenture and all
indentures supplemental thereto relating to this security.
