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 15^th 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

A-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 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

A-6

Issuer nor the Trustee nor any authorized agent of the Issuer or the Trustee shall be affected by any notice to the contrary.

This Note, including the validity hereof, and the Indenture shall be governed by and construed in accordance with the laws of the State of New York, and for all purposes shall be construed in accordance with the laws of such state, except as may otherwise be required by mandatory provisions of law.
