March 15 and September 15 in each year, commencing September 15, 2018, at the rate of 4.400% per annum, on the basis of a 360-day year consisting of twelve
30-day months, until the principal hereof is paid or duly provided for or made available for payment, and (to the extent that the payment of such interest shall be legally enforceable) at the rate of 4.400%
per annum on any overdue principal and premium and on any overdue installment of interest.

 REVERSE OF SECURITY 

This Security 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 April 11, 2007 as supplemented by the first supplemental indenture dated as of August 9, 2013 (herein called the “Indenture”), between the Company and The Bank of New
York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), 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 Security
is one of the series designated on the face hereof, initially limited in aggregate principal amount to $500,000,000. 
 All terms used in
this Security that are defined in the Indenture shall have the meaning assigned to them in the Indenture. 
 Prior to September 15,
2047, the Company shall have the right, at its option, to redeem this Security, at any time in whole, or from time to time in part, in multiples of $1,000, at a redemption price equal to the greater of: 

1.    100% of the principal amount of the Securities of this series to be redeemed; and 

2.    the sum of the present values of the remaining scheduled payments of principal and interest on the Securities of
this series to be redeemed (assuming the Securities matured on September 15, 2047) (exclusive 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 then current Treasury Rate plus 25 basis points. 

In each case, the Company shall pay accrued and unpaid interest on the principal amount being redeemed to the Redemption Date. 

On or after September 15, 2047, the Company shall have the right, at its option, to redeem the Security, in whole or in part, at any time
at a redemption price equal to 100% of the principal amount of the Securities of this series to be redeemed plus accrued and unpaid interest to, but excluding, the redemption date. 

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a
maturity comparable to the remaining term (“Remaining Life”) of the Securities of this series 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 Securities. 
 “Comparable Treasury Price” means,
as determined by the Company, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if
the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. 

  
 1 








 “Independent Investment Banker” means one of the Reference Treasury Dealers that the
Company appoints to act as the Independent Investment Banker from time to time. 
 “Reference Treasury Dealer” means (1) each
of Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P. Morgan Securities LLC and one other primary U.S. Government securities dealer in New York City selected by U.S. Bancorp Investments, Inc. and their
respective successors, unless any of them ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), in which case the Company shall substitute another Primary Treasury Dealer and (2) any
other Primary Treasury Dealers selected by the Company. 
 “Reference Treasury Dealer Quotations” means, with respect to each
Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, 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 Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

“Treasury Rate” means, with respect to any Redemption Date, the rate per year equal to: (1) 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 establishes 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; provided that, if no maturity is within three months before or after the Remaining Life of the Securities of this series to be redeemed, 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 those yields on a straight line basis, rounding to the nearest month; or (2) 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 year equal to the semiannual 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 Company on the third Business Day preceding the Redemption Date. 

Notice of redemption shall be mailed at least 30 but not more than 60 days before the Redemption Date to each Holder of Securities of this
series to be redeemed at its registered address. The notice of redemption for such Securities shall state, among other things, the amount of Securities of this series to be redeemed (any unredeemed portion of such Securities to be in a minimum
denomination of $2,000), the Redemption Date, the manner in which the redemption price shall be calculated and the place or places that payment shall be made upon presentation and surrender of such Securities to be redeemed. Unless the Company
defaults in the payment of the redemption price together with accrued interest, interest will cease to accrue on any Securities of this series that have been called for redemption on the Redemption Date. The Company shall notify the Trustee of the
redemption price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

  
 2 








 In the event of redemption of this Security in part only, a new Security or Securities of this
series for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 Installments of
accrued and unpaid interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of the Securities of this series, or one or more Predecessor Securities, registered as such at the close of business on the
relevant Regular Record Dates according to their terms. 
 The Indenture contains provisions for satisfaction, discharge and defeasance of
the entire indebtedness on this Security, upon compliance by the Company with certain conditions set forth therein. 
 If an Event of
Default with respect to Securities of this series 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 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 of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the
time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all
Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be
conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security 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 Security. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair
the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the
Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and interest on this Security are payable, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series,
of authorized denominations and for the same aggregate principal amount, will be a issued to the designated transferee or transferees. 

  
 3 








 The Securities of this series are issuable only in registered form without coupons in
denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of
Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same. 
 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. 

The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the
owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 

THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
