instrument; or”.

Assets caused by the application of the proceeds of additional Debt. 
 (b) In addition to the limitation set forth in

before the date on which such additional Debt is to be incurred shall have been less than 1.5 times the Maximum Annual Service Charge on the Debt of the Company and all Subsidiaries on a consolidated basis determined in accordance with GAAP to be
outstanding immediately after the incurrence of such additional Debt. 
 (c) For purposes of this Section 1004, Debt shall
be deemed to be “incurred” by the Company or a Subsidiary whenever the Company or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof.” 

The amendment of Section 1004 of the Indenture relates solely to the rights of the Holders of the Notes and shall not

under the Securities Exchange Act of 1934, with the Trustee) prior to such declaration or other action and (ii) $20,000,000; PROVIDED, HOWEVER, that the foregoing limitation shall not apply to any declaration or other action referred to above
which is necessary to maintain the Company’s status as a “real estate investment trust” under the Internal Revenue Code of 1986, as amended, if the aggregate principal amount of all outstanding Debt of the Company and its Subsidiaries
on a consolidated basis determined in accordance with GAAP at such time is less than 65% of the Undepreciated Real Estate Assets as of the end of the Company’s latest fiscal quarter covered in the Company’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 Securities Exchange Act of 1934, with the Trustee) prior to such declaration or other action. 

Notwithstanding the foregoing, the provisions of this Section 1005 will not prohibit the payment of any dividend within 30 days of
the declaration thereof if at such date of declaration such payment would have complied with the provisions hereof.” 
 The amendment of Section 1005 of the Indenture relates solely to the rights of the Holders of the Notes and shall not affect the rights under the Indenture of the Holders of Securities of any other
series. 
 Section 1015 of the Indenture is hereby amended in its entirety as follows:

Company’s and its Subsidiaries’ outstanding Secured Debt on a consolidated basis is greater than 40% of the sum of (i) the Total Assets as of the end of the Company’s fiscal quarter covered in the Company’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 Securities Exchange Act of 1934, with the Trustee) prior to the incurrence of such additional
Secured Debt and (ii) the increase, if any, in Total Assets from the end of such quarter including, without limitation, any increase in Total Assets caused by the application of the proceeds of additional Debt.”

 DDR CORP., an Ohio corporation (herein referred to as the “Company,” which term includes any successor corporation
under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to CEDE & CO., c/o The Depository Trust Company, 55 Water Street, New York, New York 10041, or registered assigns, the principal sum of THREE
HUNDRED MILLION Dollars ($300,000,000) on May 15, 2023 (the “Stated Maturity Date”), unless redeemed prior to such date in accordance with the provisions referred to on the reverse hereof (the Stated Maturity Date or date of earlier
redemption, as the case may be, is referred to herein as the “Maturity Date” with respect to the principal payable on such date), and to pay interest on the outstanding principal amount hereof from May 23, 2013 or from the most recent
Interest Payment Date (as defined below) to which interest has been paid or duly provided for, on May 15 and November 15, of each year, commencing November 15, 2013 (each, an “Interest Payment Date”), and on the Maturity
Date, at a rate of 3.375% per annum, computed on the basis of a 360-day year consisting of twelve 30-day months, until the principal hereof is paid or duly provided for. 

  
 A-1

 The interest so payable, and punctually paid or duly provided for, on any Interest Payment
Date and on the Maturity Date will, as provided in the Indenture, be paid to the Holder in whose name this Note (or one or more predecessor Notes) is registered at the close of business on the Regular Record Date for such interest, which shall be
fifteen calendar days (whether or not a Business Day, as defined below) next preceding such Interest Payment Date or the Maturity Date, as the case may be (each, a “Regular Record Date”). Any such 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 Special Record Date for
the payment of such Defaulted Interest to be fixed by the Trustee referred to on the reverse hereof, notice whereof shall be given to Holders of Notes of this series not less than 10 days prior to such Special Record Date, or may be paid at any time

respect of which interest has been paid or duly provided for (or from and including May 23, 2013, if no interest has been paid on this Note) to but excluding such Interest Payment Date or the Maturity Date, as the case may be. If any Interest
Payment Date or the Maturity Date falls on a day that is not a Business Day, principal, premium, if any, and/or interest payable with respect to such Interest Payment Date or Maturity 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 Maturity 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 New York City, New York, are authorized or required by law, regulation or executive order to close.

 All payments of principal, premium, if any, and interest by the Company in respect of this Note will be made by wire transfer
of immediately available funds. 
 Reference is hereby made to the further provisions of this Note 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 Note shall not be entitled to any benefit under the Indenture, or be valid or obligatory for any purpose.

 [REVERSE OF NOTE] 
 DDR CORP. 
 3.375% Notes Due 2023 

This Note is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be
issued in one or more series under an Indenture, dated as of May 1, 1994, as supplemented by the First Supplemental Indenture dated as of May 10, 1995, the Second Supplemental Indenture dated as of July 18, 2003, the Third
Supplemental Indenture dated as of January 23, 2004, the Fourth Supplemental Indenture dated as of April 22, 2004, the Fifth Supplemental Indenture dated as of April 28, 2005, the Sixth Supplemental Indenture dated as of
October 7, 2005, the Seventh Supplemental Indenture dated as of August 28, 2006, the Eighth Supplemental Indenture dated as of March 13, 2007, the Ninth Supplemental Indenture dated as of September 30, 2009, the Tenth

the “Indenture”), between the Company and U.S. Bank National Association, as successor trustee to U.S. Bank Trust National Association, as successor to National City Bank (herein called the “Trustee,” which term includes any
successor trustee under the Indenture with respect to the series of which this Note 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 Company, 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 Note is one of the duly authorized series of Securities
designated as “3.375% Notes Due 2023” (collectively, the “Notes”), and the aggregate principal amount of the Notes to be issued under such series is limited to $300,000,000 (except for Notes authenticated and delivered upon
transfer of, or in exchange for, or in lieu of other Notes). The Company may, without the consent of the Holders of any Securities, create and issue additional notes in the future having the same terms other than the date of original issuance, the
issue price and the date on which interest begins to accrue so as to form a single series with the Notes. No additional notes may be issued if an Event of Default has occurred with respect to the Notes. The Notes are the unsecured and unsubordinated
obligations of the Company and rank equally with all existing and future unsecured and unsubordinated indebtedness of the Company. All terms used but not defined in this Note shall have the meanings assigned to such terms in the Indenture.

 If an Event of Default shall occur and be continuing, the principal of the Securities of this series may be declared due and
payable in the manner and with the effect provided in the Indenture. 
 The Company may redeem the Notes at its option, at any
time prior to the Maturity Date, in whole or from time to time in part, at a Redemption Price equal to the greater of (a) 100% of the principal amount of the Notes being redeemed and (b) the sum of the present values of the remaining
scheduled payments of principal and interest through the Maturity Date on the Notes 

  
 A-4

 
being redeemed (not including the portion of any payments of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Rate plus 25 basis points, plus, in each case, any interest accrued but not paid to the Redemption Date; provided however, that if the Company redeems the Notes 90 days or fewer prior to the Stated Maturity
Date, the Redemption Price will equal 100% of the principal amount of the Notes being redeemed plus any interest accrued but not paid to the Redemption Date. For the avoidance of doubt, any calculation of the remaining scheduled payments of
principal and interest pursuant to the preceding sentence shall not include interest accrued as of the applicable Redemption Date. 
 “Treasury Rate” means, with respect to any Redemption Date for the Notes, (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the
most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which established yields on actively traded United States
Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Maturity Date,
yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest
month) or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated by the
Independent Investment Banker on the third Business Day preceding the Redemption Date. 
 “Comparable Treasury Issue”
means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes. 
 “Independent Investment Banker” means one of the Reference Treasury Dealers that has been appointed by the Company. 
 “Comparable Treasury Price” means with respect to any Redemption Date for the Notes (i) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the
highest and lowest of such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 

“Reference Treasury Dealer” means UBS Securities LLC, Jefferies LLC, RBS Securities Inc. and Scotia Capital (USA) Inc., or one
of their affiliates, and one nationally recognized investment banking firm that is a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”) appointed by U.S. Bancorp Investments, Inc., and their
respective successors, and two other Primary Treasury Dealers appointed by the Company, provided that prior written 

  
 A-5

 
notice of the Company’s appointment of such other Primary Treasury Dealers shall be provided to the Trustee; provided, further, that if any of the foregoing shall cease to be a Primary
Treasury Dealer, the Company shall substitute in its place another Primary Treasury Dealer. 
 “Reference Treasury Dealer
Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day preceding such Redemption Date. 
 Notice of any redemption will be mailed by first-class mail at least 30 days but not more than 60 days before the Redemption Date to each Holder of Notes to be redeemed. If the Company redeems less than
all of the Notes, the Trustee will select the particular Notes to be redeemed pro rata, by lot or by another method the Trustee deems fair and appropriate. 
 This Note is not subject to any sinking fund. 
 The Indenture contains provisions
for defeasance of (i) the entire indebtedness of the Notes or (ii) certain covenants and Events of Default with respect to the Notes, in each case upon compliance with certain conditions set forth therein, which provisions apply to the
Notes. 
 The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the
rights and obligations of the Company and the rights of the Holders of the Securities under the Indenture at any time by the Company 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 Company 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 of the
Outstanding Securities of any series, in certain instances, 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
Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and other Notes 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 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 Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note 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 Note is registrable in
the Security Register of the Company upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of, premium, if any, and interest on this Note are payable, duly endorsed by, or

 A-6

 
Company and the Security Registrar duly executed by, the Holder hereof or by his attorney duly authorized in writing, and thereupon one or more new Notes, 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 Note is exchangeable for a like aggregate principal amount of Notes of different authorized denominations but otherwise having the same terms and conditions, as requested by the
Holder hereof surrendering the same. 
 The Notes 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 Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Note is registered as the
owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 The Indenture and the Notes shall be governed by and construed in accordance with the laws of the State of Ohio applicable to agreements made and to be performed entirely in such State.
