WASHINGTON PRIME GROUP, L.P.

3.850% Senior Note due 2020

Washington Prime Group, L.P., an Indiana limited partnership (the “Operating Partnership,” which term includes any successor under the Indenture (as defined below)), for value received, hereby promises to pay to Cede & Co. or its registered assigns, the principal amount of [PRINCIPAL AMOUNT IN WORDS] dollars (or such lesser amount as shall be the outstanding principal amount of this Note shown in Schedule A hereto) on April 1, 2020 (the “Stated Maturity Date”), unless earlier redeemed as described on the reverse hereof, and to pay interest on the outstanding principal amount hereof from, and including, March 24, 2015, semi- annually in arrears on April 1 and October 1 of each year (each, an “Interest Payment Date”), commencing on October 1, 2015, at the rate of 3.850% per annum, until payment of said principal amount has been made or duly provided for.

The interest so payable and punctually paid or duly provided for on any Interest Payment 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 “Regular Record Date” for such payment, which shall be March 15 or September 15, as the

1

case may be, immediately prior to such Interest Payment Date, regardless of whether such day is a Business Day.  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 either 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 Special Record Date for the payment of such defaulted interest to be fixed by the Trustee (which shall not be more than 15 days and not less than 10 days prior to the date of the proposed payment of such defaulted interest) established by notice given by mail by or on behalf of the Operating Partnership to the Holders of the Notes not more than 15 days and not less than 10 days prior to the 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 Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. 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 or the Stated Maturity Date or date of earlier redemption shall be the amount of interest accrued from, and including, the immediately preceding Interest Payment Date (or from, and including, March 24, 2015, in the case of the initial period) to, but excluding, such Interest Payment Date or the Stated Maturity Date or such date of earlier redemption, as the case may be. If any Interest Payment Date or the Stated Maturity Date or date of earlier redemption falls on a day that is not a Business Day, the principal, premium, if any, and/or interest payable with respect to such date shall be made on the next succeeding Business Day with the same force and effect as if made on such date, and no interest shall accrue on the amount so payable for the period from and after such date to such next succeeding Business Day.

The principal of this Note payable on the Stated Maturity Date or date of earlier redemption shall be paid against presentation and surrender of this Note at the office or agency of the Operating Partnership maintained for that purpose in The Borough of Manhattan, The City of New York. The Operating Partnership 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 Operating Partnership in respect of the Notes or the Indenture may be served.

Payments of principal, premium, if any, 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. 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 the Indenture.

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.
