SECTION 1.01.      Definitions.  Capitalized terms used in this Eighteenth
Supplemental Indenture and not otherwise defined shall have the meanings

in New York, New York are open for business.

America.

being redeemed or paid and the amount of interest (exclusive of interest
accrued to the date of redemption or accelerated payment) that would 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, determined on the third
Business Day preceding the date notice of such redemption or accelerated
payment is given, from the respective dates on which such principal and
interest would have been payable if such redemption or accelerated payment had
not been made, to the date of redemption or accelerated payment, over
(ii) the aggregate principal amount of the Notes being redeemed or

maturities, rounding each of such relevant periods to the nearest month. For
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. If the format or content of the Statistical Release changes in a
manner that precludes determination of the Treasury Yield in the above manner,
then the Treasury Yield shall be determined in the manner that most closely

SECTION 2.02.      Definitions. As used herein:

 

“Annualized EBITDA”
means, for the four consecutive quarters ending on each Reporting Date, the
Operating Partnership’s Pro Rata Share (as defined below) of earnings
before interest, taxes, depreciation and amortization, with other adjustments
as are necessary to exclude the effect of all realized or unrealized gains and
losses related to hedging obligations, items classified as extraordinary items
and impairment charges in accordance with generally accepted accounting
principles, adjusted to reflect the assumption that (i) any EBITDA related
to any assets acquired or placed in service since the first day of such
four-quarter period had been earned, on an annualized basis, from the beginning
of such period, and (ii) any assets disposed of during such four-quarter
period had been disposed of as of the first day of such period and no EBITDA
related to such assets had been earned during such period.

Reporting Date, the Operating Partnership’s Pro Rata Share of interest expense,
with other adjustments as are necessary to exclude the effect of items
classified as extraordinary items, in accordance with generally accepted
accounting principles, reduced by amortization of debt issuance costs and
adjusted to reflect the assumption that (i) any interest expense related
to indebtedness incurred since the first day of such four-quarter period is
computed as if such indebtedness had been incurred as of the beginning of such
period, and (ii) any interest expense related to indebtedness that was
repaid or retired since the first day of such four-quarter period is computed
as if such indebtedness had been repaid or retired as of the beginning of such
period (except that, in making such computation, the amount of interest expense
related to indebtedness under any revolving credit facility shall be computed
based upon the average daily balance of such indebtedness during such
four-quarter period).

 

“Capitalization Rate”
means 7.00%.

through unconsolidated joint ventures, as determined in accordance with
generally accepted accounting principles, (iii) reimbursement

actually issued and called, (iv) any lease of property by the Operating
Partnership or any Subsidiary as lessee which is reflected in the Operating

Partnership or any Subsidiary to be liable for, or to pay, as obligor,
guarantor or otherwise, items of indebtedness of another Person (other than the
Operating Partnership or any Subsidiary) described in
clauses (i) through (iv) above (or, in the case of any such
obligation made jointly with another Person, the Operating Partnership’s or
Subsidiary’s allocable portion of such obligation based on its ownership
interest in the related real estate assets); and provided, further,
that Debt excludes Intercompany Debt (as defined below).

 

“Intercompany Debt”
means Debt to which the only parties are the Company, the Operating Partnership
and any of their Subsidiaries or affiliates (but only so long as such Debt is
held solely by any of the Company, the Operating Partnership and any Subsidiary
or affiliate) that is subordinate in right of payment to the Notes.

 

“Pro Rata Share”
means any applicable figure or measure of the Operating Partnership and its
Subsidiaries on a consolidated basis, less any portion attributable to minority
interests, plus the Operating Partnership’s or its Subsidiaries’ allocable
portion of such figure or measure, based on their ownership interest, of
unconsolidated joint ventures.

such asset becomes stabilized four Reporting Dates after the earlier of
(a) six Reporting Dates after substantial completion of construction or
development or (b) the first Reporting Date on which the asset is at least
90% leased.

 

“Total Assets”
means, as of any Reporting Date, the sum of (i) for Stabilized Assets,
Capitalized Value; (ii) for all other assets of the Operating Partnership
and its Subsidiaries, the Operating Partnership’s Pro Rata Share of
undepreciated book value as determined in accordance with generally accepted
accounting principles; and (iii) the Operating Partnership’s Pro Rata
Share of cash and cash equivalents.

 

“Unencumbered Annualized
EBITDA” means Annualized EBITDA less any portion thereof
attributable to assets serving as collateral for Secured Debt.

of the Issuer (or of any Subsidiary, the repayment of which the Issuer has
guaranteed or for which the Issuer is directly responsible or liable as obligor
or guarantor), whether such indebtedness now exists or shall hereafter be
created, which default shall constitute a failure to pay an aggregate principal
amount exceeding $50,000,000 of such indebtedness when due and payable after
the expiration of any applicable grace period with respect thereto and shall
have resulted in such indebtedness in an aggregate principal amount exceeding
$50,000,000 becoming or being declared due and payable prior to the date on
which it would otherwise have become due and payable, without such indebtedness
having been discharged, or such acceleration having been rescinded or annulled,
within a period of 30 days after there shall have been given, by registered or
certified mail, to the Issuer by the Trustee or to the Issuer and the Trustee
by the Holders of at least 25% in principal amount of the Outstanding

of Default” hereunder; or”

 

SECTION 2.04.      Notice of Defaults. For the
purposes of the Notes, Section 601 of the Original Indenture is hereby replaced
in its entirety by the following; provided, however that Section 601 of

Trustee in good faith determine that the withholding of such notice is in the
interests of the Holders of the Securities and Coupons of such series; and
provided further that in the case of any default or breach of the character
specified in Section 501(4) with respect to the Securities and Coupons of
such series, no such notice to Holders shall be given until at least 90 days

SIMON PROPERTY GROUP, L.P.

 

[5.600
/ 5.875]% Note due [2011 / 2017]

 

Simon Property Group, L.P., a Delaware 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 [SIX
HUNDRED MILLION / FIVE HUNDRED MILLION] dollars on [September 1, 2011 / March
1, 2017] (the “Maturity Date”), and to pay interest thereon from August 29,
2006, semi-annually in arrears on March 1 and September 1 of each year (each,
an “Interest Payment Date”), commencing on March 1, 2007, and on the Maturity
Date, at the rate of [5.600 / 5.875]% 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 shall be
paid to the Holder in whose name this Note (or one or more predecessor
Notes) is registered in the Security Register applicable to this Note at
the close of business on the “Record Date” for such payment, which shall be the
15th calendar day immediately prior to such payment date or the
Maturity Date, as the case may be, regardless of whether such day is a Business
Day (as defined below). Any interest 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 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 less
than 10 calendar 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 calendar days preceding
such subsequent record date, or may be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange on 

 

A-1

 

which the Notes may be listed, and upon such notice as
may be required by such exchange, all as more fully provided in the Indenture
(as defined below). Interest on this Note shall be computed on the basis of a
360-day year of twelve 30-day months.

 

Interest payable on this Note on any Interest Payment
Date and on the Maturity Date, as the case may be, shall be the amount of
interest accrued from and including the immediately preceding Interest Payment
Date (or from and including August 29, 2006, 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 date for the payment of
principal, premium, if any, interest on, or any other amount with respect to,
this Note (each a “Payment Date”) falls on a day that is not a Business
Day, the principal, premium, if any, or interest payable with respect to such
Payment Date shall be made on the next succeeding Business Day with the same
force and effect as if made on such Payment Date, and no interest shall accrue
on the amount so payable for the period from and after such Payment Date to
such next succeeding Business Day. “Business Day” means any day, other than a
Saturday or a Sunday on which banking institutions in New York, New York are
open for business.

 

The principal of this Note payable on the Maturity
Date shall be paid against presentation and surrender of this Note at the
office or agency of the Issuer maintained for that purpose in The Borough of
Manhattan, The City of New York. The Issuer hereby initially designates the
Corporate Trust Office of the Trustee in The City of New York as the office to
be maintained by it where Notes may be presented for payment, registration of
transfer or exchange, and where notices to or demands upon the Issuer in
respect of the Notes or the Indenture referred to on the reverse hereof may be
served.

 

Payments of principal and interest in respect of this
Note shall 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 after the Trustee’s Certificate of
Authentication. 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 or be valid or obligatory for any purpose until the Certificate of
Authentication hereon shall have been signed by the Trustee under such
Indenture.

 

Capitalized terms used herein which are not otherwise
defined shall have the respective meanings assigned to them in the Indenture
and the Eighteenth Supplemental Indenture hereinafter referred to.

[REVERSE
OF NOTE]

 

SIMON
PROPERTY GROUP, L.P.

 

[5.600
/ 5.875]% Note due [2011 / 2017]

 

This security is one of a duly authorized issue of
debt securities of the Issuer (hereinafter called the “Securities”), issued or
to be issued under and pursuant to an Indenture dated as of November 26,
1996 (herein called the “Indenture”), duly executed and delivered by the Issuer
to JPMorgan Chase Bank, N.A. (as successor to The Chase Manhattan Bank), as
Trustee (herein called the “Trustee,” which term includes any successor trustee
under the Indenture with respect to the series of Securities of which this Note
is a part), to which Indenture and all indentures supplemental thereto relating
to this Note (including, without limitation, the Eighteenth Supplemental
Indenture, dated as of August 29, 2006, between the Issuer and the
Trustee) reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Issuer and the Holders of the Securities, and of the terms upon
which the Securities are, and are to be, authenticated and delivered and for
the definition of capitalized terms used hereby and not otherwise defined. 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 provisions (if any), and may otherwise vary as provided in the
Indenture or any indenture supplemental thereto. This Security is one of a
series designated as the Simon Property Group, L.P. [5.600 / 5.875]% Notes due
[2011 / 2017], initially limited in aggregate principal amount to [$600,000,000
/ $500,000,000] (the “Notes”).

 

In case an Event of Default with respect to the Notes
shall have occurred and be continuing, the principal amount of the Notes and
the Make-Whole Amount may be declared accelerated and thereupon become due and
payable, in the manner, with the effect, and subject to the conditions provided
in the Indenture.

 

The Notes may be redeemed 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 sum of (i) 100% of 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. If the Notes are
redeemed on or after 90 days prior to the Maturity Date, the redemption price
shall not include the Make-Whole Amount. Notice of any optional redemption
shall 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 shall specify, among other items, the
redemption price and the principal amount of the Notes to be redeemed.

 

The Indenture contains provisions permitting the
Issuer and the Trustee, with the consent of the Holders of not less than a
majority of the aggregate principal amount of the Securities at the time
Outstanding of all series to be affected (voting as one class), 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
Outstanding Security so affected, (i) change the Stated Maturity of the
principal of, or premium, (if any) or any installment of principal of or
interest on, any Security, or reduce the principal amount thereof or the rate
or amount of interest thereon or any premium payable upon the redemption or
acceleration thereof, or adversely affect any right of repayment at the option
of the Holder of any Security, or change any Place of Payment where, or the currency
or currencies, currency unit or units or composite currency or currencies in
which, the principal of any Security or any premium or interest thereon is
payable, or impair the right to institute suit for the

thereof, against any partner of the Issuer, whether limited or general,
including Simon Property Group, Inc. or such partner’s assets or against any
principal, shareholder, officer, director, trustee or employee of such partner.

SIMON PROPERTY GROUP, L.P.

 

[5.600
/ 5.875]% Note due [2011 / 2017]

 

Simon Property Group, L.P., a Delaware limited
partnership (the “Issuer,” which term includes any successor under the
Indenture hereinafter referred to), for value received, hereby promises to pay
to                                                ,
or registered assigns, the principal sum of [SIX HUNDRED MILLION / FIVE HUNDRED
MILLION] dollars on [September 1, 2011 / March 1, 2017] (the “Maturity Date”),
and to pay interest thereon from August 29, 2006, semi-annually in arrears on
March 1 and September 1 of each year (each, an “Interest
Payment Date”), commencing on March 1, 2007, and on the Maturity Date, at the
rate of [5.600 / 5.875]% 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 shall be
paid to the Holder in whose name this Note (or one or more predecessor
Notes) is registered in the Security Register applicable to this Note at
the close of business on the “Record Date” for such payment, which shall be the
15th calendar day immediately prior to such payment date or the
Maturity Date, as the case may be, regardless of whether such day is a Business
Day (as defined below). Any interest 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 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 less
than 10 calendar 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 calendar days preceding
such subsequent 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 Notes may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture (as defined below).
Interest on this Note shall be computed on the basis of a 360-day year of
twelve 30-day months.

 

Interest payable on this Note on any Interest Payment
Date and on the Maturity Date, as the case may be, shall be the amount of
interest accrued from and including the immediately preceding Interest Payment
Date (or from and including August 29, 2006, 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 date for the payment of principal,
premium, if any, interest on, or any other amount with respect to, this Note
(each a “Payment Date”) falls on a day that is not a Business Day, the
principal, premium, if any, or interest payable with respect to such Payment
Date shall be made on the next succeeding Business Day with the same force and
effect as if made on such Payment Date, and no interest shall accrue on the
amount so payable for the period from and after such Payment Date to such next
succeeding Business Day. “Business Day” means any day, other than a Saturday or
a Sunday on which banking institutions in New York, New York are open for
business.

 

B-1

 

The principal of this Note payable on the Maturity
Date shall be paid against presentation and surrender of this Note at the
office or agency of the Issuer maintained for that purpose in The Borough of
Manhattan, The City of New York. The Issuer hereby initially designates the
Corporate Trust Office of the Trustee in The City of New York as the office to
be maintained by it where Notes may be presented for payment, registration of
transfer or exchange, and where notices to or demands upon the Issuer in
respect of the Notes or the Indenture referred to on the reverse hereof may be
served.

 

Payments of principal and interest in respect of this
Note shall 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 after the Trustee’s Certificate of
Authentication. 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 or be valid or obligatory for any purpose until the Certificate of
Authentication hereon shall have been signed by the Trustee under such
Indenture.

 

Capitalized terms used herein which are not otherwise
defined shall have the respective meanings assigned to them in the Indenture
and the Eighteenth Supplemental Indenture hereinafter referred to.

[REVERSE
OF NOTE]

 

SIMON
PROPERTY GROUP, L.P.

 

[5.600
/ 5.875]% Note due [2011 /
2017]

 

This security is one of a duly authorized issue of
debt securities of the Issuer (hereinafter called the “Securities”), issued or
to be issued under and pursuant to an Indenture dated as of November 26,
1996 (herein called the “Indenture”), duly executed and delivered by the Issuer
to JPMorgan Chase Bank, N.A. (as successor to The Chase Manhattan Bank), as
Trustee (herein called the “Trustee,” which term includes any successor trustee
under the Indenture with respect to the series of Securities of which this Note
is a part), to which Indenture and all indentures supplemental thereto relating
to this Note (including, without limitation, the Eighteenth Supplemental Indenture,
dated as of August 29, 2006, between the Issuer and the Trustee) reference
is hereby made for a description of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Issuer and
the Holders of the Securities, and of the terms upon which the Securities are,
and are to be, authenticated and delivered and for the definition of
capitalized terms used hereby and not otherwise defined. 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
provisions (if any), and may otherwise vary as provided in the Indenture or any
indenture supplemental thereto. This Security is one of a series designated as
the Simon Property Group, L.P. [5.600 / 5.875]% Notes due [2011 / 2017],
initially limited in aggregate principal amount to [$600,000,000 /
$500,000,000] (the “Notes”).

 

In case an Event of Default with respect to the Notes
shall have occurred and be continuing, the principal amount of the Notes and
the Make-Whole Amount may be declared accelerated and thereupon become due and
payable, in the manner, with the effect, and subject to the conditions provided
in the Indenture.

 

The Notes may be redeemed 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 sum of (i) 100% of 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. If the Notes are
redeemed on or after 90 days prior to the Maturity Date, the redemption price
shall not include the Make-Whole Amount. Notice of any optional redemption
shall 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 shall specify, among other items, the
redemption price and the principal amount of the Notes to be redeemed.

 

The Indenture contains provisions permitting the
Issuer and the Trustee, with the consent of the Holders of not less than a
majority of the aggregate principal amount of the Securities at the time
Outstanding of all series to be affected (voting as one class), 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
Outstanding Security so affected, (i) change the Stated Maturity of the
principal of, or premium, (if any) or any installment of principal of or
interest on, any Security, or reduce the principal amount thereof or the rate
or amount of interest thereon or any premium payable upon the redemption or
acceleration thereof, or adversely affect any right of repayment at the option
of the Holder of any Security, or change any Place of Payment where, or the
currency or currencies, currency unit or units or composite currency or
currencies in which, the principal of any Security or any premium or interest
thereon is payable, or impair the right to institute suit for the 

 

B-5

 

enforcement of any such payment on or after the Stated
Maturity thereof, or (ii) reduce the aforesaid percentage of Securities
the Holders of which are required to consent to any such supplemental
indenture, or (iii) reduce the percentage of Securities the Holders of
which are required to consent to any waiver of compliance with certain
provisions of the Indenture or any waiver of certain defaults and consequences
thereunder or to reduce the quorum or voting requirements set forth in the
Indenture, or (iv) effect certain other changes to the Indenture or any
supplemental indenture or in the rights of Holders of the Securities. The
Indenture also permits the Holders of a majority in principal amount of the
Outstanding Securities of any series (or, in the case of certain defaults or
Events of Default, all series of Securities), on behalf of the Holders of all
the Securities of such series (or all of the Securities, as the case may be),
to waive compliance by the Issuer with certain provisions of the Indenture and
certain past defaults or Events of Default under the Indenture and their
consequences, prior to any declaration accelerating the maturity of such
Securities, or subject to certain conditions, rescind a declaration of
acceleration and its consequences with respect to such Securities. Any such
consent or waiver by the Holder of this Note (unless revoked as provided in the
Indenture) shall be conclusive and binding upon such Holder and upon all
future Holders of this Note and of any Note that may be issued in exchange or
substitution hereof, irrespective of whether or not any notation thereof is
made upon this Note or such other 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
Issuer, which is absolute and unconditional, to pay the principal of, premium,
if any, and interest on this Note in the manner, at the respective times, at
the rate and in the coin or currency herein prescribed.

 

Notwithstanding any other provision of the Indenture
to the contrary, no recourse shall be had, whether by levy or execution or
otherwise, for the payment of any sums due under the Securities, including,
without limitation, the principal of, premium, if any, or interest payable
under the Securities, or for the payment or performance of any obligation
under, or for any claim based on, the Indenture or otherwise in respect
thereof, against any partner of the Issuer, whether limited or general,
including Simon Property Group, Inc. or such partner’s assets or against any
principal, shareholder, officer, director, trustee or employee of such partner.
It is expressly understood that the sole remedies under the Securities and the
Indenture or under any other document with respect to the Securities, against
such parties with respect to such amounts, obligations or claims shall be
against the Issuer.

 

This Note is issuable only in registered form without
Coupons in denominations of $2,000 and integral multiples of $1,000 in excess
thereof. This Note may be exchanged for a like aggregate principal amount of
Notes 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
this Note at the office or agency of the Issuer in The Borough of Manhattan,
The City of New York, one or more new Notes of authorized denominations in an
equal aggregate principal amount shall 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 and any authorized agent of
the Issuer or the Trustee may deem and treat the Person in whose name this Note
is registered as the absolute owner of this Note (whether or not this Note
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

SIMON PROPERTY GROUP, L.P.

 

5.60%
Note due 2011

 

Simon Property Group, L.P., a Delaware 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 Six Hundred
Million dollars on September 1, 2011 (the “Maturity Date”), and to pay interest
thereon from August 29, 2006, semi-annually in arrears on March 1 and September
1 of each year (each, an “Interest Payment Date”), commencing on March 1, 2007,
and on the Maturity Date, at the rate of 5.60% 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 shall be
paid to the Holder in whose name this Note (or one or more predecessor
Notes) is registered in the Security Register applicable to this Note at
the close of business on the “Record Date” for such payment, which shall be the
15th calendar day immediately prior to such payment date or the
Maturity Date, as the case may be, regardless of whether such day is a Business
Day (as defined below). Any interest 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 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 less
than 10 calendar 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 calendar days preceding
such subsequent 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 Notes may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in the Indenture (as defined below). Interest
on this Note shall be computed on the basis of a 360-day year of twelve 30-day
months.

 

 

Interest payable on this Note on any Interest Payment
Date and on the Maturity Date, as the case may be, shall be the amount of
interest accrued from and including the immediately preceding Interest Payment
Date (or from and including August 29, 2006, 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 date for the payment of principal,
premium, if any, interest on, or any other amount with respect to, this Note
(each a “Payment Date”) falls on a day that is not a Business Day, the
principal, premium, if any, or interest payable with respect to such Payment
Date shall be made on the next succeeding Business Day with the same force and
effect as if made on such Payment Date, and no interest shall accrue on the
amount so payable for the period from and after such Payment Date to such next
succeeding Business Day. “Business Day” means any day, other than a Saturday or
a Sunday on which banking institutions in New York, New York are open for
business.

 

The principal of this Note payable on the Maturity
Date shall be paid against presentation and surrender of this Note at the
office or agency of the Issuer maintained for that purpose in The Borough of
Manhattan, The City of New York. The Issuer hereby initially designates the
Corporate Trust Office of the Trustee in The City of New York as the office to
be maintained by it where Notes may be presented for payment, registration of
transfer or exchange, and where notices to or demands upon the Issuer in
respect of the Notes or the Indenture referred to on the reverse hereof may be
served.

 

Payments of principal and interest in respect of this
Note shall 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 after the Trustee’s Certificate of
Authentication. 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 or be valid or obligatory for any purpose until the Certificate of
Authentication hereon shall have been signed by the Trustee under such
Indenture.

 

Capitalized terms used herein which are not otherwise
defined shall have the respective meanings assigned to them in the Indenture
and the Eighteenth Supplemental Indenture hereinafter referred to.

SIMON
PROPERTY GROUP, L.P.

 

5.60%
Note due 2011

 

This security is one of a duly authorized issue of
debt securities of the Issuer (hereinafter called the “Securities”), issued or
to be issued under and pursuant to an Indenture dated as of November 26,
1996 (herein called the “Indenture”), duly executed and delivered by the Issuer
to JPMorgan Chase Bank, N.A. (as successor to The Chase Manhattan Bank), as
Trustee (herein called the “Trustee,” which term includes any successor trustee
under the Indenture with respect to the series of Securities of which this Note
is a part), to which Indenture and all indentures supplemental thereto relating
to this Note (including, without limitation, the Eighteenth Supplemental
Indenture, dated as of August 29, 2006, between the Issuer and the
Trustee) reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Issuer and the Holders of the Securities, and of the terms upon
which the Securities are, and are to be, authenticated and delivered and for
the definition of capitalized terms used hereby and not otherwise defined. 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 provisions (if any), and may otherwise vary as provided in the
Indenture or any indenture supplemental thereto. This Security is one of a
series designated as the Simon Property Group, L.P. 5.60% Notes due 2011,
initially limited in aggregate principal amount to $600,000,000 (the “Notes”).

 

In case an Event of Default with respect to the Notes
shall have occurred and be continuing, the principal amount of the Notes and the
Make-Whole Amount may be declared accelerated and thereupon become due and
payable, in the manner, with the effect, and subject to the conditions provided
in the Indenture.

 

The Notes may be redeemed 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 sum of (i) 100% of 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. If the Notes are
redeemed on or after 90 days prior to the Maturity Date, the redemption price
shall not include the Make-Whole Amount. Notice of any optional redemption
shall 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 shall specify, among other items, the
redemption price and the principal amount of the Notes to be redeemed.

 

The Indenture contains provisions permitting the
Issuer and the Trustee, with the consent of the Holders of not less than a
majority of the aggregate principal amount of the Securities at the time
Outstanding of all series to be affected (voting as one class), 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
Outstanding Security so affected, (i) change the Stated Maturity of the
principal of, or premium, (if any) or any installment of principal of or
interest on, any Security, or reduce the principal amount thereof or the rate
or amount of interest thereon or any premium payable upon the redemption or
acceleration thereof, or adversely affect any right of repayment at the option
of the Holder of any Security, or change any Place of Payment where, or the
currency or currencies, currency unit or units or composite currency or
currencies in which, the principal of any Security or any premium or interest
thereon is payable, or impair the right to institute suit for the enforcement
of any such payment on or after the Stated Maturity thereof, or
(ii) reduce the aforesaid

percentage of Securities the Holders of which are
required to consent to any such supplemental indenture, or (iii) reduce
the percentage of Securities the Holders of which are required to consent to
any waiver of compliance with certain provisions of the Indenture or any waiver
of certain defaults and consequences thereunder or to reduce the quorum or
voting requirements set forth in the Indenture, or (iv) effect certain
other changes to the Indenture or any supplemental indenture or in the rights
of Holders of the Securities. The Indenture also permits the Holders of a
majority in principal amount of the Outstanding Securities of any series (or,
in the case of certain defaults or Events of Default, all series of
Securities), on behalf of the Holders of all the Securities of such series (or
all of the Securities, as the case may be), to waive compliance by the Issuer
with certain provisions of the Indenture and certain past defaults or Events of
Default under the Indenture and their consequences, prior to any declaration
accelerating the maturity of such Securities, or subject to certain conditions,
rescind a declaration of acceleration and its consequences with respect to such
Securities. Any such consent or waiver by the Holder of this Note (unless
revoked as provided in the Indenture) shall be conclusive and binding upon
such Holder and upon all future Holders of this Note and of any Note that may
be issued in exchange or substitution hereof, irrespective of whether or not
any notation thereof is made upon this Note or such other 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
Issuer, which is absolute and unconditional, to pay the principal of, premium,
if any, and interest on this Note in the manner, at the respective times, at
the rate and in the coin or currency herein prescribed.

 

Notwithstanding any other provision of the Indenture
to the contrary, no recourse shall be had, whether by levy or execution or
otherwise, for the payment of any sums due under the Securities, including,
without limitation, the principal of, premium, if any, or interest payable
under the Securities, or for the payment or performance of any obligation
under, or for any claim based on, the Indenture or otherwise in respect
thereof, against any partner of the Issuer, whether limited or general,
including Simon Property Group, Inc. or such partner’s assets or against any
principal, shareholder, officer, director, trustee or employee of such partner.
It is expressly understood that the sole remedies under the Securities and the Indenture
or under any other document with respect to the Securities, against such
parties with respect to such amounts, obligations or claims shall be against
the Issuer.

 

This Note is issuable only in registered form without
Coupons in denominations of $2,000 and integral multiples of $1,000 in excess
thereof. This Note may be exchanged for a like aggregate principal amount of
Notes of other authorized denominations at the office or agency of the Issuer

except for any tax or other governmental charge imposed in connection

The Issuer, the Trustee and any authorized agent of
the Issuer or the Trustee may deem and treat the Person in whose name this Note
is registered as the absolute owner of this Note (whether or not this Note
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 and any premium hereof or hereon, 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.
