     "Make-Whole Amount" means, in connection with any optional redemption or
accelerated payment of any Notes, the excess, if any, of (i) the aggregate
present value as of the date of such redemption or accelerated payment of each
dollar of principal being redeemed or paid and the amount of interest (exclusive

have been payable in respect of each such dollar if such redemption or
accelerated payment had not been made, determined by discounting, on a
semi-annual basis, such principal and interest at the Reinvestment Rate

<PAGE>   5

     "Redemption Price" has the meaning specified in Section 2.5 hereof.

     "Reinvestment Rate" means 0.25% (twenty-five one hundredths of one percent)

Week" published in the Statistical Release under the caption "Treasury Constant
Maturities" for the maturity (rounded to the nearest month) corresponding to the
remaining life to maturity, as of the payment date of the principal being
redeemed or paid. If no maturity exactly corresponds to such maturity, yields
for the two published maturities most closely corresponding to such maturity
shall be calculated pursuant to the immediately preceding sentence and the
Reinvestment Rate shall be interpolated or extrapolated from such yields on a
straight-line basis, rounding in each of such relevant periods to the nearest
month. For the purposes of calculating the Reinvestment Rate, the most recent
Statistical Release published prior to the date of determination of the
Make-Whole Amount shall be used.

     "Statistical Release" means the statistical release designated "H.15(519)"
or any successor publication which is published weekly by the Board of Governors

                               THE SERIES OF NOTES

     SECTION 2.1. TITLE OF THE SECURITIES. There is hereby created under the
Senior Indenture a series of Securities designated the "8.875% Notes due 2006"
(the "Notes").

     SECTION 2.2. LIMITATIONS ON AGGREGATE PRINCIPAL AMOUNT. The aggregate
principal amount of the Notes shall be limited to $75,000,000, and, except as
provided in this Section and in Section 301 of the Senior Indenture, the
Partnership shall not execute and the Trustee shall not authenticate or deliver
Notes in excess of such aggregate principal amount.

     Nothing contained in this Section 2.2 or elsewhere in this Supplemental
Indenture, or in the Notes, is intended to or shall limit execution by the
Partnership or authentication or delivery by the Trustee of the Notes under the
circumstances contemplated in Sections 304, 305, 306, 906, 1107 and 1305 of the
Senior Indenture.

     SECTION 2.3. INTEREST AND INTEREST RATES; MATURITY DATE OF NOTES. The Notes
will bear interest at a rate of 8.875% per annum, from March 10, 2000 or from
the immediately preceding Interest Payment Date to which interest has been paid
or duly provided for, payable semi-annually in arrears on March 15 and September
15 of each year, commencing September 15, 2000 (each, an "Interest Payment
Date"), to the Person in whose name such Note is registered at the close of
business on March 1 or September 1 (whether or not a Business Day), as the case
may be, next preceding such Interest Payment Date (each, a "Regular Record
Date"). Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months. The interest so payable on any Note which is not
punctually paid or duly provided for on any Interest Payment Date shall
forthwith cease to be payable to the Person in whose name such Note is
registered on the relevant Regular Record Date, and such defaulted interest
shall instead be payable to the Person in whose name such Note is registered on
the Special Record Date or other specified date determined in accordance with
the Senior Indenture.

     If any Interest Payment Date or Maturity falls on a day that is not a
Business Day, the required payment shall be made on the next Business Day as if
it were made on the date such

                                        6



<PAGE>   7



payment was due and no interest shall accrue on the amount so payable for the
period from and after such Interest Payment Date or Maturity, as the case may
be.

     The Notes will mature on March 15, 2006.

     SECTION 2.4. LIMITATIONS ON INCURRENCE OF DEBT. For so long as any of the
Notes remain Outstanding:

          (a) The Partnership will not, and will not permit any Subsidiary to,
incur any Indebtedness if, immediately after giving effect to the incurrence of
such additional Indebtedness and the application of the proceeds thereof, the
aggregate principal amount of all outstanding Indebtedness of the Partnership
and its Subsidiaries on a consolidated basis determined in accordance with GAAP
is greater than 60% of the sum of (without duplication) (i) the Total Assets of
the Partnership and its Subsidiaries as of the end of the calendar quarter
covered in the Partnership's Annual Report on Form 10-K or Quarterly Report on
Form 10-Q, as the case may be, most recently filed with the Commission (or, if
such filing is not permitted under the Exchange Act, with the Trustee) prior to
the incurrence of such additional Indebtedness, and (ii) the purchase price of
any real estate assets or mortgages receivable acquired since the end of the
most recent calendar quarter, and (iii) the amount of any securities offering
proceeds received (to the extent such proceeds were not used to acquire real
estate assets or mortgages receivable or used to reduce Indebtedness), by the
Partnership or any Subsidiary since the end of such calendar quarter, including
those proceeds obtained in connection with the incurrence of such additional
Indebtedness, less (iv) the decrease, if any, in the Total Assets of the
Partnership and its Subsidiaries since the end of such quarter.

          (b) In addition to the limitation set forth in subsection (a) of this
Section 2.4, the Partnership will not, and will not permit any Subsidiary to,
incur any Indebtedness if the ratio of Consolidated Income Available for Debt
Service to the Annual Service Charge for the four consecutive fiscal quarters
most recently ended prior to the date on which such additional Indebtedness is
to be incurred shall have been less than 1.5:1 on a PRO FORMA basis after giving
effect thereto and to the application of the proceeds therefrom, and calculated
on the assumption that (i) such Indebtedness and any other Indebtedness incurred
by the Partnership and its Subsidiaries since the first day of such four-quarter
period and the application of the proceeds therefrom, including to refinance
other Indebtedness, had occurred at the beginning of such period; (ii) the
repayment or retirement of any other Indebtedness by the Partnership and its
Subsidiaries since the first day of such four-quarter period had been repaid or
retired at the beginning of such period (except that, in making such
computation, the amount of Indebtedness under any revolving credit facility
shall be computed based upon the average daily balance of such Indebtedness
during such period); (iii) in the case of Acquired Indebtedness or Indebtedness
incurred in connection with any acquisition since the first day of such
four-quarter period, the related acquisition had occurred as of the first day of
such period with the appropriate adjustments with respect to such acquisition
being included in such PRO FORMA calculation; and (iv) in the case of any
acquisition or disposition by the Partnership or its Subsidiaries of any asset
or group of assets since the first day of such four-quarter period,

                                        7



<PAGE>   8



whether by merger, stock purchase or sale, or asset purchase or sale, such
acquisition or disposition or any related repayment of Indebtedness had occurred
as of the first day of such period with the appropriate adjustments with respect
to such acquisition or disposition being included in such PRO FORMA calculation.

          (c) In addition to the limitations set forth in subsections (a) and
(b) of this Section 2.4, the Partnership will not, and will not permit any
Subsidiary to, incur any Indebtedness secured by any Encumbrance upon any of the
property of the Partnership or any Subsidiary if, immediately after giving
effect to the incurrence of such additional Indebtedness and the application of
the proceeds thereof, the aggregate principal amount of all outstanding
Indebtedness of the Partnership and its Subsidiaries on a consolidated basis
which is secured by any Encumbrance on property of the Partnership or any
Subsidiary is greater than 40% of the sum of (without duplication) (i) the Total
Assets of the Partnership and its Subsidiaries as of the end of the calendar
quarter covered in the Partnership's Annual Report on Form 10-K or Quarterly
Report on Form 10-Q, as the case may be, most recently filed with the Commission
(or, if such filing is not permitted under the Exchange Act, with the Trustee)
prior to the incurrence of such additional Indebtedness and (ii) the purchase
price of any real estate assets or mortgages receivable acquired since the end
of the most recent calendar quarter, and (iii) the amount of any securities
offering proceeds received (to the extent that such proceeds were not used to
acquire real estate assets or mortgages receivable or used to reduce
Indebtedness), by the Partnership or any Subsidiary since the end of such
calendar quarter, including those proceeds obtained in connection with the
incurrence of such additional Indebtedness, less (iv) the decrease, if any, in
the Total Assets of the Partnership and its Subsidiaries since the end of such
quarter.

          (d) The Partnership and its Subsidiaries may not at any time own Total
Unencumbered Assets equal to less than 150% of the aggregate outstanding
principal amount of the Unsecured Indebtedness of the Partnership and its
Subsidiaries on a consolidated basis.

          (e) For purposes of this Section 2.4, Indebtedness shall be deemed to
be "incurred" by the Partnership or a Subsidiary whenever the Partnership or
such Subsidiary shall create, assume, guarantee or otherwise become liable in
respect thereof.

          (f) The covenants set forth in subsections (a), (b) and (c) of this
Section 2.4 shall not restrict the Partnership from refinancing existing
Indebtedness, provided that the outstanding principal amount of such
Indebtedness is not increased.

     SECTION 2.5. REDEMPTION.

          (a) The Notes shall be redeemable before their Stated Maturity in
accordance with this Section 2.5 and otherwise in accordance with the provisions
of Article Eleven of the Senior Indenture. In the event of any conflict between
this Section 2.5 (including the definitions of terms used herein) and Article
Eleven of the Senior Indenture (including the definitions of terms used
therein), this Section 2.5 shall control.

redeemed plus accrued interest thereon to the Redemption Date, and (ii) the
Make-Whole Amount, if any, with respect to such Notes (the "Redemption Price").

such Section 13 or 15(d) if the Partnership were so subject, such documents to

Indenture and with any other term, provision or condition with respect to the

least a majority in principal amount of all outstanding Notes or such series
thereof, as applicable, by Act of such Holders, either waive such compliance in
such instance or generally waive compliance with such covenant or condition.
Except to the extent so expressly waived, and until such waiver shall become

respect of any such term, provision or condition shall remain in full force and
effect.

     BRADLEY OPERATING LIMITED PARTNERSHIP, a Delaware limited partnership
(herein referred to as the "Partnership" which term includes any successor
entity under the Indenture referred to), for value received, hereby promises to
pay to CEDE & CO., or registered assigns, upon presentation, the principal sum
of SEVENTY FIVE MILLION AND NO/100 DOLLARS on March 15, 2006 (the "Stated
Maturity Date") and to pay interest thereon from March 10, 2000 or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, semi-annually on March 15 and September 15 in each year (each, an "Interest
Payment Date"), commencing September 15, 2000, at the rate of 8.875% per annum,
until the principal hereof is paid or duly provided for. The interest so
payable, and punctually paid or duly provided for, on any Interest Payment Date
will, as provided in such Indenture, be paid to the Holder in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest, which shall be the March
1 or September 1 (whether or not a Business Day), as the case may be, next
preceding such Interest Payment Date at the office or agency of the Partnership
maintained for such purpose; PROVIDED, HOWEVER, that such interest may be paid,
at the Partnership's option, by mailing a check to such Holder at its registered
address or by transfer of funds to an account maintained by such Holder within
the United States. Any such interest

                                       A-1

<PAGE>   15



not so punctually paid or duly provided for shall forthwith cease to be payable
to the Holder on such Regular Record Date, and may be paid to the Holder 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 Trustee, notice whereof shall be given to
Holders of Securities of this series 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 the
Securities of this series may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in the Indenture. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

     The principal of this Security payable on the Stated Maturity Date or the
principal of, premium or Make-Whole Amount, if any, and, if the Redemption Date
is not an Interest Payment Date, interest on this Security payable on the
Redemption Date will be paid against presentation of this Security at the office
or agency of the Partnership maintained for that purpose in Chicago, Illinois 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.

     Interest payable on this Security on any Interest Payment Date and on the
Stated Maturity Date or Redemption Date, as the case may be, will include
interest accrued from and including the next preceding Interest Payment Date in
respect of which interest has been paid or duly provided for (or from and
including March 10, 2000, if no interest has been paid on this Security) to but
excluding such Interest Payment Date or the Stated Maturity Date or Redemption
Date, as the case may be. If any Interest Payment Date or the Stated Maturity
Date or Redemption Date falls on a day that is not a Business Day, as defined
below, principal, premium or Make-Whole Amount, if any, and/or interest payable
with respect to such Interest Payment Date or Stated Maturity Date or Redemption
Date, as the case may be, will be paid on the next succeeding Business Day with
the same force and effect as if it were paid on the date such payment was due,
and no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date or Stated Maturity Date or Redemption Date, as
the case may be. "Business Day" means any day, other than a Saturday or Sunday,
that is neither a legal holiday nor a day on which banking institutions in the
City of New York or in the City of Chicago are authorized or required by law,
regulation or executive order to close.

     All payments of principal, premium or Make-Whole Amount, if any, and
interest in respect of this Security will be made by the Partnership in
immediately available funds.

     Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

     Unless the Certificate of Authentication hereon has been executed by the
Trustee by manual signature of one of its authorized signatories, this Security
shall not be entitled to any benefit under the Indenture, or be valid or
obligatory for any purpose.

                              [Reverse of Security]

                      BRADLEY OPERATING LIMITED PARTNERSHIP

     This Security is one of a duly authorized issue of securities of the
Partnership (herein called the "Securities"), issued and to be issued in one or
more series under an Indenture, dated as of November 24, 1997, as supplemented
by Supplemental Indenture No. 3, dated as of March 10, 2000 (as so supplemented,
herein called the "Indenture") between the Partnership and LaSalle Bank National
Association, as Trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture with respect to the series of which this
Security is a part), 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 Partnership, 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 duly
authorized series of Securities designated on the face hereof (collectively, the
"Securities"), and the aggregate principal amount of the Securities to be issued
under such series is initially limited to $75,000,000 (except for Securities
authenticated and delivered upon transfer of, or in exchange for, or in lieu of
other Securities). All terms used in this Security which are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

     If an Event of Default, as defined in the Indenture, with respect to the
Securities of this series, shall occur and be continuing, the principal of and
the Make-Whole Amount, if any, on the Securities of this series may be declared
due and payable in the manner and with the effect provided in the Indenture.

     The Securities are subject to redemption at any time at the option and in
the sole discretion of the Partnership in whole or from time to time in part, at
a redemption price equal to the sum of (i) the principal amount of the Notes
being redeemed plus accrued interest thereon to the Redemption Date and (ii) the
Make-Whole Amount, if any, with respect to such Notes; PROVIDED, HOWEVER, that
installments of interest on this Security whose Stated Maturity is on or prior
to such Redemption Date will be payable to the Holder of this Security, or one
or more Predecessor Securities, of record at the close of business on the
relevant Record Dates referred to on the face hereof, all as provided in the
Indenture.

     Notice of redemption will be given by mail to Holders of Securities, not
less than 30 nor more than 60 days prior to the Redemption Date, all as provided
in the Indenture.

     In the event of redemption of this Security in part only, a new Security or
Securities for the unredeemed portion hereof shall be issued in the name of the
Holder hereof upon the cancellation hereof.


                                       A-4



<PAGE>   18



     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Partnership and the rights of the Holders of the Securities under the Indenture
at any time by the Partnership and the Trustee with the consent of the Holders
of not less than a majority of the aggregate principal amount of all Securities
issued under the Indenture 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, on
behalf of the Holders of all such Securities, to waive compliance by the
Partnership 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, in certain instances, of the Outstanding Securities of any
series 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 Security shall be conclusive and binding
upon such Holder and upon all future Holders of this Security and other
Securities 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.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Partnership, which
is absolute and unconditional, to pay the principal of (and premium or
Make-Whole Amount, if any) and interest on this Security at the times, places
and rate, 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 Security is registrable in the Security
Register of the Partnership upon surrender of this Security for registration of
transfer at the office or agency of the Partnership in any place where the
principal of (and premium or Make-Whole Amount, if any) and interest on this
Security are payable, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Partnership and the Security Registrar
duly executed by, the Holder hereof or by his attorney duly authorized in
writing, and thereupon one or more new Securities, 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 Security is exchangeable for a like aggregate principal
amount of Securities of different authorized denominations but otherwise having
the same terms and conditions, as requested by the Holder hereof surrendering
the same.

     The Securities of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof.

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

                                       A-5



<PAGE>   19



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

     No recourse shall be had for the payment of the principal of or premium or
Make-Whole Amount, if any, or the interest on this Security, or for any claim
based hereon, or otherwise in respect hereof, or based on or in respect of the
Indenture or any indenture supplemental thereto, against any past, present or
future stockholder, employee, officer or director, as such, of the Partnership
or of any successor, either directly or through the Partnership or any
successor, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

     The Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York applicable to agreements made
and to be performed entirely in such State.

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Partnership 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.
