Section 2.2                                    Form of the 2024 Securities.  The Initial 2024 Securities shall be issued in the form of one or more Global Securities, duly executed by the Operating Partnership and authenticated by the Trustee without the necessity of the reproduction thereon of the corporate seal of WPG, as the general partner of the Operating Partnership, which shall be initially deposited with, or on behalf of, DTC and registered in the name of “Cede & Co.,” as the initial nominee of DTC.  If the Initial 2024 Securities are represented by one or more Global Securities, then any Additional 2024 Securities will also be represented by one or more Global Securities.  The 2024 Securities shall be substantially in the form of Exhibit A hereto.

Section 2.3                                    Terms and Conditions of the 2024 Securities.  The 2024 Securities shall be governed by all the terms and conditions of the Indenture.  In particular, the following provisions shall be terms of the 2024 Securities:

(a)                                 Title and Aggregate Principal Amount.  The title of the 2024 Securities shall be “Washington Prime Group, L.P. 5.950% Notes due 2024”; and the aggregate principal amount of the 2024 Securities shall be as specified in Section 2.1 of this Second Supplemental Indenture.

(b)                                 Stated Maturity Date.  The 2024 Securities shall mature, and the unpaid principal thereon shall be payable, on August 15, 2024, unless redeemed at the option of the Operating Partnership prior to such date in accordance with Section 2.3(e) of this Second Supplemental Indenture.

(c)                                  Interest.  The rate per annum at which interest shall be payable on the 2024 Securities shall be 5.950% subject to an increase under the circumstances set forth in Section 2.3(d) of this Second Supplemental Indenture.  Interest on the Initial 2024 Securities shall accrue from, and including, the Closing Date.  Interest on the Additional 2024 Securities shall accrue as contemplated in Section 2.3(h) of this Second Supplemental Indenture. Interest on the 2024 Securities shall be payable semi-annually in arrears on each February 15 and August 15, commencing on February 15, 2018 (each, an “Interest Payment Date”), to the Persons in whose names the applicable 2024 Securities are registered in the Security Register at the close of business on February 1 or August 1, as the case may be, immediately preceding the applicable Interest Payment Date, regardless of whether such day is a Business Day (each, a “Regular Record Date”).  Interest on the 2024 Securities shall be computed on the basis of a 360-day year of twelve 30-day months.

7

(d)                                 Interest Rate Adjustment.  (i)   The interest rate on the 2024 Securities will increase such that it will equal the interest rate payable on the 2024 Securities on the Closing Date plus 0.50%, or 50 basis points, if, at any time, at least two of Moody’s, S&P and Fitch (or, in each case, if such rating agency ceases to rate the 2024 Securities or fails to make a rating of the 2024 Securities publicly available, in each case for reasons outside of the Operating Partnership’s control, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act selected pursuant to the definition of ‘‘rating agencies’’ in substitution therefor (a “substitute rating agency”)), downgrades the credit rating assigned to the 2024 Securities to Ba1 or lower by Moody’s, BB+ or lower by S&P and/or BB+ or lower by Fitch (or, in each case the equivalent rating by any substitute rating agency).

(ii)                                  If at any time Moody’s, S&P or Fitch (or any substitute rating agency) ceases to rate the 2024 Securities or fails to make a rating of the 2024 Securities publicly available, the Operating Partnership will use its commercially reasonable efforts to obtain a rating of the 2024 Securities from a substitute rating agency, if one exists, in which case, for purposes of determining any increase in the interest rate on the 2024 Securities pursuant to Section 2.3(d)(i) of this Second Supplemental Indenture, (a) such substitute rating agency will be substituted for the last rating agency to provide a rating of the 2024 Securities but which has since ceased to provide such rating and (b) the relative rating scale used by such substitute rating agency to assign ratings to senior unsecured debt will be determined in good faith by an independent investment banking institution of national standing appointed by the Operating Partnership and, for purposes of determining the applicable ratings pursuant to Section 2.3(d)(i) of this Second Supplemental Indenture with respect to such substitute rating agency, such ratings will be deemed to be the equivalent ratings used by Moody’s, S&P or Fitch (or such substitute rating agency), as applicable, pursuant to Section 2.3(d)(i) of this Second Supplemental Indenture.

(iii)                               Notwithstanding the foregoing, (a) in the event that one or more rating agencies cease to rate the 2024 Securities or fail to make a rating of the 2024 Securities publicly available, in each case for reasons outside of the Operating Partnership’s control, and the Operating Partnership is unable to obtain a rating of the 2024 Securities from a substitute rating agency therefor, the interest rate on the 2024 Securities will increase by 0.50%, or 50 basis points, only if (1) in the case where there are only two remaining rating agencies, the credit ratings assigned to the 2024 Securities by each such rating agency are below investment grade or (2) in the case where there is only one remaining rating agency, the credit rating assigned to the 2024 Securities by such rating agency is below investment grade, (b) in the event that all of the rating agencies cease to rate the 2024 Securities or fail to make a rating of the 2024 Securities publicly available, in each case for reasons outside of the Operating Partnership’s control, and the Operating Partnership is unable to obtain a rating of the 2024 Securities from a substitute rating agency therefor, the interest rate on the 2024 Securities will be equal to the interest rate payable on the 2024 Securities on the Closing Date plus 0.50%, or 50 basis points and (c) if the interest rate on the 2024 Securities is increased as described in this Section 2.3(d) at any time, then such increase shall apply for the balance of the term of the 2024 Securities irrespective of whether the requisite credit rating remains, or credit ratings remain, as applicable, below investment grade.

(iv)                              Any interest rate increase described in this Section 2.3(d) will take effect from the first Interest Payment Date following the date on which a rating change occurs that requires an increase in the interest rate.  As such, interest will not accrue at such increased rate until the next

8

Interest Payment Date following the date on which a rating change occurs.  If Moody’s, S&P or Fitch (or, in any case, a substitute rating agency therefor) changes its rating of the 2024 Securities more than once prior to any particular Interest Payment Date, the last change by such agency prior to such Interest Payment Date will control for purposes of any interest rate increase with respect to the 2024 Securities described above relating to such rating agency’s action.  If the interest rate payable on the 2024 Securities is increased as described above, the term “interest,” as used with respect to the 2024 Securities, will be deemed to include any such additional interest unless the context otherwise requires.  The Operating Partnership will promptly notify the Trustee, in writing of any event that causes an adjustment to the interest rate on the 2024 Securities to be applicable, and, unless it has received such notice, the Trustee shall not be deemed to have knowledge of any such event.

(e)                                  Optional Redemption.  The Operating Partnership may redeem the 2024 Securities, in whole or from time to time in part, subject to the conditions and at the redemption prices set forth in the form set forth in Exhibit A hereto, which is hereby incorporated by reference and made a part of this Second Supplemental Indenture.

(f)                                   Registration and Form.  The 2024 Securities shall be issuable as Global Securities in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.  All payments of principal, premium, if any, and interest in respect of the 2024 Securities shall be made by the Operating Partnership in immediately available funds.

(g)                                  Defeasance.  The provisions for legal defeasance in Section 402 of the Base Indenture and for covenant defeasance (which provisions shall apply to the covenants set forth in Article III of this Second Supplemental Indenture) in Section 402 of the Base Indenture shall be applicable to the 2024 Securities.

(h)                                 Issuance of Additional 2024 Securities. The Operating Partnership may, from time to time, without notice to or the consent of any Holders of the 2024 Securities, create and issue additional debt securities having the same terms as the 2024 Securities of such series in all respects, except for the issue date and, under certain circumstances, the issue price, the date from which interest begins to accrue and the first payment of interest thereon, provided that such issuance complies with the covenants described herein and no such additional issuance may occur prior to the date that is six months subsequent to the Closing Date (the “Additional 2024 Securities”). The Initial 2024 Securities and any additional debt securities issued pursuant to this Section 2.3(h) shall be treated as a single series of debt securities of the Operating Partnership for all purposes under the Indenture.

With respect to any Additional 2024 Securities, the Operating Partnership shall set forth in a resolution of its Board of Directors and in an Officer’s Certificate, a copy of each of which shall be delivered to the Trustee, the following information:

(1)                                 the aggregate principal amount of such Additional 2024 Securities to be authenticated and delivered pursuant to this Second Supplemental Indenture; and

(2)                                 the issue price, the issue date, the CUSIP number of such Additional 2024 Securities, the first Interest Payment Date and the date from which interest begins to accrue.

9

(i)                                     Cancellation.  Any 2024 Securities purchased by the Operating Partnership may not be reissued or resold and will be canceled promptly.

(j)                                    Other Terms and Conditions.  The 2024 Securities shall have such other terms and conditions as provided in the form thereof attached as Exhibit A.

Section 2.4                                    Designation of Community Center Properties.  From time to time, the Operating Partnership may designate internally one or more additional properties acquired or placed in service since the date of WPG’s or the Operating Partnership’s most recent audited consolidated financial statements as Community Center Properties.  Upon the Operating Partnership’s internal designation, such property or properties shall each be deemed to be a Community Center Property for all purposes of this Second Supplemental Indenture until the next subsequent filing of Schedule III to the audited consolidated financial statements of WPG or the Operating Partnership; provided that if the Operating Partnership has not delivered within fifteen Business Days of the end of the fiscal quarter in which such property or properties were acquired or placed in service a certificate of any two of the Chief Executive Officer, the President, the Chief Financial Officer, the Chief Operations Officer and the Chief Administrative Officer of WPG, as the sole general partner of the Operating Partnership, in substantially the form attached hereto as Schedule A, to the Trustee (i) setting forth the name of such property or properties and (ii) certifying that such property or properties have been determined in good faith by each such officer to be “community centers” on the same basis as the “community centers” identified in Schedule III to such most recent audited consolidated financial statements, then such property or properties shall cease to be deemed Community Center Properties for the purpose of this Second Supplemental Indenture until such Officer’s Certificate is delivered to the Trustee.  The Trustee shall make any such Officer’s Certificate available to a Holder upon its written request.  Notwithstanding the foregoing and for the avoidance of doubt, a property shall no longer be a Community Center Property upon its sale or other disposition.

ARTICLE III

CERTAIN COVENANTS

In addition to the covenants set forth in Sections 1001 through 1004, inclusive, of the Base Indenture, there are established the following covenants for the benefit of the Holders of the 2024 Securities:

Section 3.1                                    Limitation on All Outstanding Indebtedness.  The Operating Partnership will not, and will not permit any Subsidiary to, incur any Indebtedness, if, immediately after giving effect to the incurrence of the additional Indebtedness and the application of the proceeds of such Indebtedness, the aggregate principal amount of all outstanding Indebtedness of the Operating Partnership and its Subsidiaries on a consolidated basis determined in accordance with GAAP is greater than 60% of Total Assets.

Section 3.2                                    Limitations on Incurrence of Secured Indebtedness.  The Operating Partnership will not, and will not permit any Subsidiary to, incur any Indebtedness secured by any Encumbrance upon any of its property or that of any Subsidiary if, immediately after giving effect to the incurrence of the additional Indebtedness and the application of the proceeds of such

10

Indebtedness, the aggregate principal amount of all outstanding Indebtedness of the Operating Partnership and its Subsidiaries on a consolidated basis, determined in accordance with GAAP, which is secured by any Encumbrance on its property or that of any Subsidiary is greater than 40% of Total Assets.

Section 3.3                                    Maximum Ratio of Consolidated Income Available for Debt Service to Annual Service Charge.  The Operating Partnership will not, and will not permit any Subsidiary to, incur any Indebtedness if the ratio of Consolidated EBITDA to the Annual Service Charge for the four consecutive fiscal quarters ended on the most recent Reporting Date would have been less than 1.50 to 1.00, on a pro forma basis, after giving effect to the incurrence of the additional Indebtedness and the application of the proceeds of such Indebtedness and calculated on the assumption that: (i) the additional Indebtedness and any other Indebtedness incurred by the Operating Partnership or its Subsidiaries since the first day of such four-quarter period and the application of the proceeds of such Indebtedness, including Indebtedness to refinance other Indebtedness, had occurred at the beginning of such period; (ii) the repayment or retirement of any other Indebtedness by the Operating Partnership or its Subsidiaries since the first day of such four-quarter period had been repaid or retired at the beginning of such period; (iii) in the case of Acquired Indebtedness or Indebtedness incurred in connection with any acquisition since the first day of the four-quarter period, the related acquisition had occurred as of the first day of the period with appropriate adjustments to Consolidated EBITDA for the acquisition being included in the pro forma calculation; and (iv) in the case of any acquisition or disposition by the Operating Partnership or any Subsidiary of any asset or group of assets since the first day of such four-quarter period, including, without limitation, 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 appropriate adjustments to Consolidated EBITDA for the acquisition or disposition being included in the pro forma calculation.

In applying the above assumptions to the calculation of the Annual Service Charge and Consolidated EBITDA, 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.

Section 3.4                                    General.  For purposes of the foregoing provisions, Indebtedness is deemed to be “incurred” by the Operating Partnership or a Subsidiary whenever the Operating Partnership or such Subsidiary creates, assumes, guarantees or otherwise becomes liable for such Indebtedness.

Section 3.5                                    Maintenance of Total Unencumbered Assets.  The Operating Partnership and its Subsidiaries will at all times own Total Unencumbered Assets equal to at least 150% of the aggregate outstanding principal amount of the Unsecured Indebtedness of the Operating Partnership and its Subsidiaries on a consolidated basis determined in accordance with GAAP.

WASHINGTON PRIME GROUP, L.P.

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, August 4, 2017, 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.

This Note is one of a duly authorized issue of debt securities of the Operating Partnership (collectively, the “Securities”), issued or to be issued under and pursuant to an Indenture, dated as of March 24, 2015 (as amended or supplemented from time to time, the “Indenture”), duly executed and delivered by the Operating Partnership to U.S. Bank National Association, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture with respect to the Securities of the series of which this Note is a part), to which Indenture and all indentures supplemental thereto relating to this Note (including, without limitation, the Second Supplemental Indenture, dated as of August 4, 2017 (the “Second Supplemental Indenture”), between the Operating Partnership 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 Operating Partnership 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.  This Note is one of a series designated as the Washington Prime Group, L.P. 5.950% Notes due 2024, limited in aggregate principal amount to $750,000,000, except as contemplated in the Indenture (collectively, 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 any premium due on the outstanding Notes and unpaid interest, if any, accrued thereon may be declared, and in certain cases shall automatically become, due and payable immediately, in the manner, with the effect, and subject to the conditions provided in the Indenture.

The Notes may be redeemed at the option of the Operating Partnership, in whole at any time or in part from time to time (in amounts of $2,000 and whole multiples of $1,000 in excess thereof), (x) prior to June 15, 2024, for cash, at a redemption price equal to the greater of (1) 100% of the aggregate principal amount of the Notes to be redeemed and (2) an amount equal to the sum of the present values of the remaining scheduled payments of principal of and interest on the Notes to be redeemed, calculated as if the Stated Maturity Date of the Notes were June 15, 2024, not including any portion of the payments of interest accrued to, but not including, such redemption date, discounted to such redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 0.50%, or 50 basis points, plus, in each case, accrued and unpaid interest, if any, on the principal amount of the Notes to be redeemed to, but not including, such redemption date and (y) on or after June 15, 2024, for cash, at a redemption price equal to 100% of the aggregate principal amount of the Notes to be redeemed plus accrued and unpaid interest, if any, on the principal amount of the Notes to be redeemed to, but not including, such redemption date.

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, subject to certain exceptions requiring the consent of each Holder of Securities affected thereby and certain other exceptions not requiring the consent of any Holder of Securities.  The Indenture also permits the Holders of a majority in aggregate principal amount of the Outstanding Securities of any series, 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 Operating Partnership with certain provisions of the Indenture and certain past defaults or Events of Default under the Indenture and their consequences.  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 Operating Partnership, 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.
