either be paid to the person in whose name this Security (or one or more
predecessor Securities) is registered at the close of business on a special
record date for the payment of such defaulted interest to be fixed by the
Company, notice whereof shall be given to the Trustee and the Holders not less

other lawful manner. Interest on the Securities shall be computed on the basis
of a 360-day year of twelve 30-day months.

                  Principal of and interest on the Securities will be payable in
such coin or currency of the United States of America as at the time of payment
is legal tender for payment of public and private debts, the transfer of the
Securities will be registrable, the Securities may be presented for exchange,
and notices and demands to or upon the Company in respect of this Security and
the Indenture may be served, at the office or agency of the Company maintained

                            7.25% Debenture Due 2031

1.       General.

         This Security is one of a duly authorized series of securities of the
Company issued and to be issued under an Indenture, dated as of September 10,
1997, as amended, modified or supplemented from time to time (the "Indenture"),
between the Company and The Bank of New York, 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
Security is one of the series designated on the face hereof, limited (except as
otherwise provided in the Indenture) in aggregate principal amount to
$600,000,000 (herein called the "Securities"). All terms used but not defined in
this Security shall have the meanings assigned to them in the Indenture.

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

2.       Indenture.

         The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by the Officers' Certificate dated January 31,
2001 delivered pursuant thereto and the TIA. The Securities are subject to all
such terms, and the Securityholders are referred to the Indenture and said Act
for a statement of them.

3.       Sinking Fund.

         The Securities are not subject to any sinking fund and the Securities
are not subject to redemption or repurchase by the Company at the option of the
Holders.

4.       Redemption.

         The Securities are redeemable, in whole or in part, at the option of
the Company at any time at a redemption price equal to the greater of (i) 100%
of the principal amount of the Securities to be redeemed; or (ii) as determined
by an Independent Investment Banker, the sum of the present values of the
remaining scheduled payments of principal and interest thereon (not including
any portion of such payments of interest accrued as of the date of redemption)
discounted to the redemption date on a semiannual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 25 basis
points, plus, in each case, accrued and unpaid interest thereon to the date of
redemption.

         "Adjusted Treasury Rate" means, with respect to any redemption date:
(i) the yield, under the heading which represents the average for the
immediately preceding week, appearing in the most recently published statistical
release designated "H.15(519)" or any successor publication which is published
weekly by the Board of Governors of the Federal Reserve System and which
establishes yields on actively traded United States Treasury securities adjusted
to constant maturity under the caption "Treasury Constant Maturities," for the
maturity corresponding to the Comparable Treasury Issue (if no maturity is
within three months before or after the Remaining Life of the Securities, yields
for the two published maturities most closely corresponding to the Comparable
Treasury Issue shall be determined and the Adjusted Treasury Rate shall be
interpolated or extrapolated from such yields on a straight line basis, rounding
to the nearest month); or (ii) if such release (or any successor release) is not
published during the week preceding the calculation date or does not contain
such yields, the rate per annum equal to the semi-annual equivalent yield to
maturity of the Comparable Treasury Issue, calculated using a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price for such redemption date. The Adjusted
Treasury Rate shall be calculated on the third Business Day preceding the
redemption date.

                                       4

<PAGE>   5

         "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Securities that would be utilized, at the time of
selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of comparable maturity to the remaining term
of such Securities ("Remaining Life").

         "Comparable Treasury Price" means (1) the average of five Reference
Treasury Dealer Quotations for the applicable redemption date, after excluding
the highest and lowest Reference Treasury Dealer Quotations, or (2) if the
Independent Investment Banker obtains fewer than five such Reference Treasury
Dealer Quotations, the average of all such quotations.

         "Independent Investment Banker" means one of the Reference Treasury
Dealers appointed by the Trustee after consultation with the Company.

         "Reference Treasury Dealer" means (i) each of Chase Securities Inc. and
Salomon Smith Barney Inc. and their respective successors; provided, however,
that if either of the foregoing shall cease to be a primary U.S. Government
securities dealer in New York City (a "Primary Treasury Dealer"), the Company
shall substitute therefor another Primary Treasury Dealer and (ii) any other
Primary Treasury Dealer selected by the Trustee after consultation with the
Company.

         "Reference Treasury Dealer Quotation" means, with respect to each
Reference Treasury Dealer and any redemption date for the Securities, the
average, as determined by the Independent Investment Banker, of the bid and
asked prices for the Comparable Treasury Issue (expressed in each case as a
percentage of its principal amount) quoted in writing to the Independent
Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City
time, on the third Business Day preceding such redemption date.

         Notice of any redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each Holder of the Securities to be
redeemed.

5.       Denominations; Transfer; Exchange.

         This Security is issuable only in registered form without coupons in
minimum denominations of U.S. $1,000 and integral multiples thereof.

         As provided in the Indenture and subject to certain limitations therein
and herein set forth, the transfer, or the exchange for an equal principal
amount, of this Security is registrable with the Registrar upon surrender of
this Security for registration of transfer at the office or agency of the
Registrar.

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

6.       Persons Deemed Owners.

         Prior to due presentment of this Security 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 Security is registered as the owner thereof for
all purposes, whether or not this Security be overdue, and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary.

7.       Unclaimed Money.

         The Trustee and any Paying Agent shall pay to the Company upon request
any money held by them for the payment of principal and interest that remains
unclaimed for two years. After that,

                                       5

<PAGE>   6

Securityholders entitled to the money must look to the Company for payment as
general creditors unless an applicable abandoned property law designates another
person.

8.       Defeasance Prior to Maturity.

         The Indenture contains provisions for defeasance of (i) the entire
indebtedness of the Securities or (ii) certain covenants and Events of Default
with respect to the Securities, in each case upon compliance with certain
conditions set forth therein.

9.       Amendment; Supplement; Waiver.

         Subject to certain limitations described in the Indenture, the
Indenture permits the Company and the Trustee to enter into a supplemental
indenture with the written consent of the Holders of at least a majority in
principal amount of the outstanding Securities (including consents obtained in
connection with a tender offer or exchange offer for the Securities), for the
purpose of 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 Securityholders. Subject to certain limitations
described in the Indenture, the Holders of at least a majority in principal
amount of the outstanding Securities by notice to the Trustee (including
consents obtained in connection with a tender offer or exchange offer for the
Securities) may waive compliance by the Company with any provision of the
Indenture or the Securities. Any such consent or waiver by the Holder of this
Security shall be conclusive and binding upon such Holder and upon all future
Holders of this Security and of any Security issued upon the registration of
transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

10.      Restrictive Covenants.

         The Indenture imposes certain limitations on the Company's and its
Subsidiaries' ability to create or incur certain Liens on any of their
respective properties or assets and to enter into certain sale and lease-back
transactions and on the Company's ability to engage in mergers or consolidations
or the conveyance, transfer or lease of all or substantially all of its
properties and assets. These limitations are subject to a number of important
qualifications and exceptions and reference is made to the Indenture for a
description thereof.

11.      Defaults and Remedies.

         If an Event of Default shall occur and be continuing, the principal of
the Securities may be declared (or, in certain cases, shall ipso facto become)
due and payable in the manner and with the effect provided in the Indenture.

12.      Proceedings.

         As provided in and subject to the provisions of the Indenture, the
Holder of this Security shall not have the right to institute any proceeding,
judicial or otherwise, with respect to the Indenture or for the appointment of a
receiver or trustee, or for any other remedy under the Indenture, unless such
Holder shall have previously given the Trustee written notice of a continuing
Event of Default with respect to the Securities and unless also the Holders of
at least a majority in principal amount of the Securities at the time
outstanding shall have made written request, and offered reasonable indemnity,
to the Trustee to institute such proceedings as trustee, and the Trustee shall
not have received from the Holders of a majority in principal amount of
Securities at the time outstanding a direction inconsistent with such request,
and shall have failed to institute such proceeding, within 60 days. The
foregoing shall not apply to any suit instituted by the Holder of this Security
for the enforcement of any payment of the principal hereof or any interest
hereon on or after the respective due dates expressed herein.

13.      Trustee Dealings with Company.

         The Trustee under the Indenture, in its individual or any other
capacity, may deal with the Company or an Affiliate of the Company with the same
rights it would have if it were not Trustee.

                                       6

14.      No Recourse Against Others.

         A past, present or future director, officer, employee, shareholder or
incorporator, as such, of the Company or any successor corporation shall not
have any liability for any obligations of the Company under this Security or the
Indenture or for any claim based on, in respect of, or by reason of such
obligations or their creation. Each Securityholder by accepting a Security
waives and releases all such liability. The waiver and release are part of the
consideration of issuance of the Securities.

15.      Governing Law.

         The internal laws of the State of New York shall govern the Indenture
and the Securities.

       AMB PROPERTY, L.P., a Delaware limited partnership (hereinafter called
the "Operating Partnership", which term includes any successor under the
Indenture referred to below), for value received, hereby promises to pay to the
Registered Holder specified on the face hereof, or registered assigns
("Holder"), upon presentation and surrender of this Note, on the Maturity Date
specified on the face hereof (except to the extent repaid or redeemed prior to
the Maturity Date) the Principal Amount specified on the face hereof in the
Specified Currency specified on the face hereof, and to pay interest thereon at
the Interest Rate per annum specified on the face hereof, until the principal
hereof is paid or duly made available for payment.

       Unless otherwise specified on the face hereof, the Operating Partnership
will pay interest (other than defaulted interest) on each Interest Payment Date
(as defined below), commencing with the first Interest Payment Date next
succeeding the Original Issue Date specified on the face hereof, to the person
who is the Holder of this Note on the applicable Regular Record Date (as defined
below); provided that if the Original Issue Date occurs between a Regular Record
Date and an Interest Payment Date, the Operating Partnership will make the first
payment of interest on the Interest Payment Date following the next Regular
Record Date to the registered owner on that Regular Record Date.

       The Operating Partnership will pay interest due on the Maturity Date,
Redemption Date (as defined on the reverse hereof) or Repayment Date (as defined
on the reverse hereof), as applicable, to the same person to whom it is paying
the principal amount; provided that if the Operating Partnership would have made
a regular interest payment on the Maturity Date, Redemption Date or Repayment
Date, as the case may be, it will make that regular interest payment to the
Holder as of the applicable Regular Record Date, even if it is not the same
person to whom it is paying the principal amount.

       Any such interest not so punctually paid or duly provided for ("Defaulted
Interest") will forthwith cease to be payable to the Holder on any Regular
Record Date, and shall be paid, at the election of the Operating Partnership, to
either (i) to the Holder 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 (as defined on the reverse hereof), notice whereof shall be given to
the Holder of this Note by the Trustee not less than 10 calendar days prior to
such Special Record Date or (ii) 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.

       Unless specified on the face hereof, payments of interest on this Note
with respect to any Interest Payment Date, Maturity Date, Redemption Date or
Repayment Date, as applicable, will include interest accrued from and including
each immediately preceding Interest Payment Date (or from and including the
Original Date of Issue if no interest has been paid or duly provided for), to,
but excluding, the Interest Payment Date, Maturity Date, Redemption Date or
Repayment Date, as the case may be.

       If an Interest Payment Date, Maturity Date, Redemption Date or Repayment
Date, as applicable, falls on a day that is not a Business Day (as defined
below), interest (or interest and principal) will be paid on the next Business
Day; provided that interest on the payment will not accrue for the period from
the original Interest Payment Date, Maturity Date, Redemption Date or Repayment
Date, as the case may be, to the date of such payment on the next Business Day.

       Unless otherwise specified on the face hereof, the "Interest Payment
Dates" shall be June 30 and December 30 of each year. The "Regular Record Dates"
shall be June 15 for a June 30 interest payment date, December 15 for a December
30 interest payment date and the date that is 15 calendar days before any other
interest payment date, whether or not those dates are Business Days.

       "Business Day" as used herein means any day, other than a Saturday or
Sunday, (a) that is neither a legal holiday nor a day on which banking
institutions are authorized or required by law or regulation to close (x) in The
City of New York or (y) for notes denominated in a specified currency other than
U.S. dollars, Australian dollars or euro, in the principal financial center of
the country of the specified currency or (z) for notes denominated in Australian
dollars, in Sydney, and (b) for notes denominated in euro, that is also a day on
which the Trans-European

                                       1
<PAGE>   3

Automated Real-time Gross Settlement Express Transfer System, which is commonly
referred to as "TARGET," is operating.

       Payment of principal (and premium, if any) and interest on, this Note on
any day, if the Holder of this Note is DTC (or its nominee or other depository,
a "Depository"), will be made in accordance with any applicable provisions of
such written agreement between the Operating Partnership, the Trustee and the
Depository (or its nominee) as may be in effect from time to time. Otherwise
payment of principal (and premium, if any) and interest on, this Note on any day
shall be payable and this Note may be surrendered for the registration of
transfer or exchange at the Office of the Trustee's affiliate, State Street Bank
and Trust Company, at 61 Broadway, 15th Floor, New York, New York 10006;
provided, however, that at the option of the Operating Partnership, interest may
be paid by check mailed to the address of the Person entitled thereto as such
address shall appear in the Operating Partnership's Security Register or by wire
transfer, if proper wire instructions are on file with the Trustee or are
received at presentment, to an account maintained by the payee located in the
United States. The place where notices or demands to or upon the Operating
Partnership in respect of this Note and the Indenture may be served shall be the
Corporate Trust Office of the Trustee at 633 West Fifth Street, 12th Floor, Los
Angeles, California 90071.

       To receive payment of a U.S. dollar denominated Note upon redemption (if
applicable) or at maturity, a Holder must make presentation and surrender of
such Note on or before the Redemption Date or Maturity Date, as applicable. To
receive payment of a Note denominated in a Foreign Currency (as defined on the
reverse hereof) upon redemption or at maturity, a Holder must make presentation
and surrender of such Note not less than two Business Days prior to the
Redemption Date or Maturity Date, as applicable. Upon presentation and surrender
of a Note denominated in a Foreign Currency at any time after the date two
Business Days prior to the Redemption Date or Maturity Date, as applicable, the
Operating Partnership will pay the principal amount (and premium, if any) of
such Note, and any interest due upon redemption or at maturity (unless the
Redemption Date or Maturity Date is an Interest Payment Date), two Business Days
after such presentation and surrender.

       For procedures relating to the receipt of payment upon repayment, if
applicable, see the reverse hereof.

       The Operating Partnership will pay any administrative costs imposed by
banks in connection with sending payments by wire transfer, but any tax,
assessment or governmental charge imposed upon payments will be borne by the
Holders of the Notes in respect of which payments are made.

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

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

       Notwithstanding the foregoing, if an Addendum is attached hereto or
"Other/Additional Provisions" apply to this Note as specified on the face
hereof, this Note shall be subject to the terms set forth in such Addendum or
such "Other/Additional Provisions."

                                (REVERSE OF NOTE)

                                AMB PROPERTY L.P.
                                MEDIUM-TERM NOTE
                                  (FIXED RATE)

       This Note is one of a duly authorized issue of debt securities of the
Operating Partnership (hereinafter called the "Securities") of the series
hereinafter specified, unlimited in aggregate principal amount, all issued or to
be issued under or pursuant to an Indenture dated as of June 30, 1998, among the
Operating Partnership, AMB Property Corporation, a Maryland corporation and
general partner of the Operating Partnership (the "Guarantor"), and State Street
Bank and Trust Company of California, N.A., as Trustee; to which Indenture and
all indentures supplemental thereto (herein collectively called the "Indenture")
reference is hereby made for a specification of the rights and limitation of
rights thereunder of the Holders of the Securities, the rights and obligations
thereunder of the Operating Partnership and the rights, duties and immunities
thereunder of the Trustee. The Securities may be issued in one or more series,
which different series may be issued in various aggregate principal amounts, may
mature at different times, may bear interest (if any) at different rates, may be
subject to different redemption or repayment provisions (if any), may be subject
to different covenants and defaults and may otherwise vary as provided in the
Indenture. This Note is one of a series designated as "Medium-Term Notes"
(hereinafter referred to as the "Notes") of the Operating Partnership, of up to
$400,000,000 in aggregate principal amount. All terms used in this Note which
are defined in the Indenture and which are not otherwise defined in this Note
shall have the meanings assigned to them in the Indenture. The terms of the
Notes include those stated in the Indenture and those made a part of the
Indenture by reference to the Trust Indenture Act of 1939, as amended. The Notes
are subject to all such terms, and the Holders are referred to the Indenture and
such Act for a statement of such terms. To the extent any provision of this Note
conflicts with the provisions of the Indenture, the provisions of the Indenture
shall govern and be controlling.

       Unless stated to the contrary on the face hereof, this Note is issuable
only in registered form without coupons in Book-Entry form represented by one or
more global notes (each a "Global Note") recorded in the book-entry system
maintained by the Depository. If specified on the face hereof, this Note is
issuable in certificated form issued to, and registered in the name of, the
beneficial owner or its nominee (a "Certificated Note").

       Unless a different minimum Authorized Denomination is set forth on the
face hereof, this Note is issuable in minimum denominations of (i) if the
Specified Currency of this Note is US dollars, U.S. $1,000 and in any larger
amount in integral multiples of $1,000 and (ii) if the Specified Currency of
this Note is a currency other than US dollars (a "Foreign Currency"), the
equivalent in such Foreign Currency determined in accordance with the Market
Exchange Rate (as defined below) for such Foreign Currency on the Business Day
immediately preceding the date on which the Operating Partnership accepts an
offer to purchase a Note, of U.S. $1,000 (rounded to an integral multiple of
1,000 units of the Foreign Currency), and in any larger amount in integral
multiples of 1,000 units.

       If this is a Global Note representing Book-Entry Notes, this Note may be
transferred or exchanged only through DTC. In the manner and subject to the
limitations provided in the Indenture, if this is a Certificated Note, it may be
transferred or exchanged, without charge except for any tax or other
governmental charge imposed in relation thereto, for other Notes of authorized
denominations for a like aggregate principal amount, at the office or agency of
the Operating Partnership in the Borough of Manhattan of The City of New York,
or, at the option of the Holder, such office or agency, if any, maintained by
the Operating Partnership in the city in which the principal executive offices
of the Operating Partnership are located or the city in which the principal
corporate trust office of the Trustee is located.

       The principal (and premium, if any) and interest on, this Note is payable
by the Operating Partnership in the Specified Currency.

       If this Note is denominated in a Foreign Currency, in the event that the
Foreign Currency is not available for payment at a time at which any payment is
required hereunder due to the imposition of exchange controls or other
circumstances beyond the control of the Operating Partnership or is no longer
used by the government of the

                                       2
<PAGE>   6

country issuing such currency or for the settlement of transactions by public
institutions within the international banking community, the Operating
Partnership may, in full satisfaction of its obligation to make such payment,
make instead a payment in an equivalent amount of US dollars, determined by the
Exchange Rate Agent, as specified on the face hereof, on the basis of the Market
Exchange Rate for such Foreign Currency 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; provided, however,
that if such Specified Currency is replaced by a single European currency, the
payment of principal of (and premium, if any) or interest, if any, on this Note
denominated in such currency shall be effected in the new single European
currency in conformity with legally applicable measures taken pursuant to, or by
virtue of, the treaty establishing the European Community, as amended by the
treaty on European Unity. 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 U.S. dollars or a new single European
currency where the required payment is in a Specified Currency other than U.S.
dollars or such single European currency, respectively, will not constitute an
Event of Default (as defined in the Indenture).

       If the Specified Currency is a composite currency and if such composite
currency is unavailable due to the imposition of exchange controls or other
circumstances beyond the control of the Operating Partnership, then the
Operating Partnership will be entitled to satisfy its obligations to the Holder
of this Note by making such payment in U.S. dollars. The amount of each payment
in U.S. dollars shall be computed by the Exchange Rate Agent on the basis of the
equivalent of the composite currency in U.S. 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 U.S.
dollars shall be calculated by aggregating the U.S. dollar equivalents of the
Component Currencies. The U.S. dollar equivalent of each of the Component
Currencies shall be determined by the Exchange Rate Agent 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.

       If a Redemption Commencement Date is specified on the face hereof, this
Note may be redeemed, whether or not any other Note is concurrently redeemed, at
the option of the Operating Partnership, in whole, or from time to time in part,
on any Business Day on or after such Redemption Commencement Date and prior to
the Maturity Date, upon mailing by first-class mail, postage prepaid, a notice
of such redemption not less than 30 nor more than 60 days prior to the actual
date of redemption ("Redemption Date"), to the Holder of this Note at such
Holder's address appearing in the Security Register, as provided in the
Indenture (provided that, if the Holder of this Note is a Depository or a
nominee of a Depository, notice of such redemption shall be given in accordance
with any applicable provisions of such written agreement between the Operating
Partnership, the Trustee and such Depository (or its nominee) as may be in
effect from time to time), at the Redemption Price (as defined below), together
in each case with interest accrued to the Redemption Date (subject to the right
of the Holder of record on a Regular Record Date to receive interest due on an
Interest Payment Date). The "Redemption Price" shall be equal to (i) the Initial
Redemption Percentage specified on the face of this Note, as adjusted downward
on each anniversary of the Redemption Commencement Date by the Annual Redemption
Price Reduction, if any, specified on the face hereof, multiplied by (ii) the
unpaid Principal Amount of this Note to be redeemed. In the event of

                                       3
<PAGE>   7

redemption of this Note in part only, a new Note or Notes of this series, and of
like tenor, for the unredeemed portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

       If an Optional Repayment Date(s) is specified on the face hereof, this
Note will be subject to repayment by the Operating Partnership at the option of
the Holder hereof on such Optional Repayment Date(s), in whole or in part in
increments of U.S. $1,000, at the Repayment Price specified on the face hereof,
together with unpaid interest accrued hereon to the date of repayment
("Repayment Date"). For this Note to be repaid, this Note must be received,
together with the form hereon entitled "Option to Elect Repayment" duly
completed, by the Trustee at the corporate trust office of the Trustee's
Affiliate, State Street Bank and Trust Company, at 61 Broadway Street, New York,
New York (or at such other address of which the Operating Partnership shall from
time to time designate and notify Holders of the Notes) at least 30 but not more
than 60 days prior to the Repayment Date. 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 is a Global Note representing Book-Entry Notes, only the
Depository may exercise the repayment option in respect of this Note.
Accordingly, if this is a Global Security representing Book-Entry Notes and the
beneficial owner desires to have all or any portion of the Book-Entry Note
represented by this Global Security repaid, the beneficial owner must instruct
the participant through which he owns his interest to direct the Depository to
exercise the repayment option on his behalf by delivering this Note and duly
completed election form to the Trustee as aforesaid.

       If this Note is an Original Issue 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 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) multiplied, in the event of any redemption or
repayment of this Note (if applicable), by the Redemption Price or Repayment
Price, as the case may be, 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, as specified on the face hereof, 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.

       In case a default, as defined in the Indenture, shall occur and be
continuing with respect to the Notes, the principal amount of all Notes then
outstanding under the Indenture may be declared or may become due and payable
upon the conditions and in the manner and with the effect provided in the
Indenture. The Indenture provides that such declaration may in certain events be
annulled by the Holders of a majority in principal amount of the Notes
outstanding.

       To the extent permitted by, and as provided in, the Indenture, the
Operating Partnership may enter into one or more supplements to the Indenture
for the purpose of modifying or altering the Indenture, without the consent of
any Holders of Notes, for the limited purposes described in the Indenture.

       To the extent permitted by, and as provided in, the Indenture, the
Operating Partnership may enter into one or more supplements to the Indenture
for the purpose of modifying or altering the rights and obligations of the

                                       4
<PAGE>   8

Operating Partnership and the Holders of the Securities (as defined in the
Indenture) with the consent of the Holders of not less than a majority in
principal amount of all Outstanding Securities (as defined in the Indenture) of
any series affected, evidenced as provided in the Indenture.

       The Indenture contains provisions for legal defeasance and covenant
defeasance with respect to the Notes, in each case, upon compliance with certain
conditions set forth therein, which provisions apply to the Notes.

       The Operating Partnership, the Trustee, any Authenticating Agent, any
paying agent and any Security registrar may deem and treat the registered Holder
hereof as the absolute owner hereof (whether or not this Note shall be overdue
and notwithstanding any notice of ownership or other writing hereon by anyone
other than the Operating Partnership or any Security registrar) for the purpose
of receiving payment of or on account of the principal hereof (and premium, if
any), and interest hereon, and for all other purposes, and none of the Operating
Partnership, the Trustee, an Authenticating Agent, a paying agent nor the
Security registrar shall be affected by any notice to the contrary. All such
payments shall be valid and effectual to satisfy and discharge the liability
upon this Note to the extent of the sum or sums so paid.

       No recourse under or upon any obligation, covenant or agreement of the

any such payment to be made punctually when and as the same shall become due and
payable, whether at the Maturity Date, upon acceleration, by redemption or
repayment or otherwise, and as if such payment were made by the Operating
Partnership. The undersigned hereby agrees, jointly and severally with the
Subsidiary Guarantors, if any, that its obligations hereunder shall be as
principal and not merely as surety, and shall be absolute and unconditional, and
shall not be affected, modified or impaired by the following: (a) the failure to
give notice to the Guarantors of the occurrence of an Event of Default under the
Indenture; (b) the waiver, surrender, compromise, settlement, release or
termination of the payment, performance or observance by the Operating
Partnership or the Guarantors of any or all of the obligations, covenants or
agreements of either of them contained in the Indenture or any Note; (c) the
acceleration, extension or any other changes in the time for payment of any

or any of the assets of any of them, or any allegation or contest of the
validity of this Parent Guarantee in any such proceeding; (h) to the extent
permitted by law, the release or discharge by operation of law of the Guarantors
from the performance or observance of any obligation, covenant or agreement
contained in the Indenture; (i) to the extent permitted by law, the release or
discharge by operation of law of the Operating Partnership from the performance

Indenture; (j) the default or failure of the Operating Partnership or the

affecting the Operating Partnership or any Note or consent or indulgence granted
to the Operating Partnership by the Holders or by the Trustee; or (m) the
recovery of any judgment against the Operating Partnership or any action to

equitable discharge of a surety or guarantor. The undersigned hereby waives
diligence, presentment, demand of payment, filing of claims with a court in the
event of merger, sale, lease or conveyance of all or substantially all of its
assets, insolvency or bankruptcy of any Guarantor or the Operating Partnership,
any right to require a proceeding first against any other Guarantor or the
Operating Partnership, protest or notice with respect to such Note or the
indebtedness evidenced thereby and all demands whatsoever, and covenants that
this Parent Guarantee will not be discharged except by complete performance of
the obligations contained in such Note and in this Parent Guarantee.

       No reference herein to such Indenture and no provision of this Parent
Guarantee or of such Indenture shall alter or impair the guarantee of the
undersigned, which is absolute and unconditional, of the full and prompt payment
of the principal of and premium, if any, and interest on the Note.

<PAGE>   10

       THIS PARENT GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK.

       This Parent Guarantee shall not be valid or obligatory for any purpose
until the certificate of authentication on the Note shall have been executed by
the Trustee under the Indenture referred to above by the manual signature of one
of its authorized officers. The validity and enforceability of this Parent
Guarantee shall not be affected by the fact that it is not affixed to any
particular Note.

       An Event of Default under the Indenture or any Note shall constitute an
event of default under this Parent Guarantee, and shall entitle the Holder of
the Note to accelerate the obligations of the undersigned hereunder in the same
manner and to the same extent as the obligations of the Operating Partnership.

       Notwithstanding any other provision of this Parent Guarantee to the
contrary, the undersigned hereby waives any claims or other rights which it may
now have or hereafter acquire against any other Guarantor or the Operating
Partnership that arise from the existence or performance of its obligations
under this Parent Guarantee (all such claims and rights are referred to as
"Guarantor's Conditional Rights"), including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution, or indemnification, any
right to participate in any claim or remedy against any Guarantor or the
Operating Partnership, whether or not such claim, remedy or right arises in
equity or under contract, statute or common law, by any payment made hereunder
or otherwise, including without limitation, the right to take or receive from
any Guarantor or the Operating Partnership, directly or indirectly, in cash or
other property or by setoff or in any other manner, payment or security on
account of such claim or other rights. The undersigned hereby agrees not to
exercise any rights which may be acquired by way of contribution under this
Parent Guarantee or any other agreement, by any payment made hereunder or
otherwise, including, without limitation, the right to take or receive from any
other guarantor, directly or indirectly, in cash or other property or by setoff
or in any other manner, payment or security on account of such contribution
rights. If, notwithstanding the foregoing provisions, any amount shall be paid
to the undersigned on account of the Guarantor's Conditional Rights and either
(i) such amount is paid to such undersigned party at any time when the
indebtedness shall not have been paid or performed in full, or (ii) regardless
of when such amount is paid to such undersigned party, any payment made by any
Guarantor or the Operating Partnership to a Holder that is at any time
determined to be a Preferential Payment (as defined below), then such amount
paid to the undersigned shall be held in trust for the benefit of such Holder
and shall forthwith be paid such Holder to be credited and applied upon the
indebtedness, whether matured or unmatured. Any such payment is herein referred
to as a "Preferential Payment" to the extent any Guarantor or the Operating
Partnership makes any payment to such Holder in connection with the Note, and
any or all of such payment is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid or paid over to a
trustee, receiver or any other entity, whether under any bankruptcy act or
otherwise.

       To the extent that any of the provisions of the immediately preceding
paragraph shall not be enforceable, the undersigned agrees that until such time
as the indebtedness has been paid and performed in full and the period of time
has expired during which any payment made by any Guarantor, the Operating
Partnership or the undersigned to a Holder may be determined to be a
Preferential Payment, Guarantor's Conditional Rights to the extent not validly
waived shall be subordinate to Holders' right to full payment and performance of
the indebtedness and the undersigned shall not enforce any of Guarantor's
Conditional Rights until such time as the indebtedness has been paid and
performed in full and the period of time has expired during which any payment
made by any Guarantor, the Operating Partnership or the undersigned to Holders
may be determined to be a Preferential Payment.

       The obligations of the undersigned to the Holder of the Note and to the
Trustee pursuant to this Parent Guarantee and the Indenture are expressly set
forth in Article 14 of the Indenture and reference is hereby made to the
Indenture for the precise terms of this Parent Guarantee and all of the other
provisions of the Indenture to which this Parent Guarantee relates.

       Capitalized terms used in this Parent Guarantee which are not defined
herein shall have the meanings assigned to them in the Indenture.

       IN WITNESS WHEREOF, the undersigned has caused this Parent Guarantee to
be duly executed.
