and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes of or within the Series pursuant to Section 304, 305, 306, 906, 1107 or 1305 of the Base Indenture); provided, the Company may increase such
aggregate principal amount upon the action of the Board to do so from time to time. 
 3.    The Notes shall bear interest at the rate
of 3.875% per annum. The aggregate principal amount of the Notes is payable at maturity on September 15, 2028. The interest on this Series shall accrue from June 20, 2018 or from the most recent Interest Payment Date (as defined below) to
which interest has been paid or duly provided for. Interest on the Notes shall be payable semi-annually in arrears on March 15 and September 15 of each year (each an “Interest Payment Date”), commencing on
September 15, 2018. Interest shall be paid to persons in whose names the Notes are registered on the March 1 and September 1 preceding the Interest Payment Date, whether or not a Business Day (each a “Regular Record Date”).

 4.    The principal of (and premium or Make-Whole Amount, if any), interest, if any, on the Notes shall be payable, and the Notes may
be surrendered for registration of transfer or exchange and notices or demands to or upon the Company in respect of the Notes and the Indenture may be served at the Corporate Trust Office of the Trustee (including for these purposes, its office,
located at 100 Wall Street, Suite 1600, New York, New York 10005). 
 5.    At any time prior to the Par Call Date, the Notes will be
redeemable in whole at any time or in part from time to time at the option of the Company, upon notice of not more than 60 nor less than 15 days prior to the Redemption Date, at a Redemption Price calculated by the Company and equal to the sum of
(1) 100% of the principal amount of the Notes to be redeemed 

 
plus accrued and unpaid interest, if any, to, but not including, the Redemption Date plus (2) the Make-Whole Premium. 

In addition, on and after the Par Call Date, the Notes will be redeemable in whole at any time or in part from time to time, at the option of
the Company, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date. 

The following definitions apply with respect to the Make-Whole Amount: 

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having
a maturity comparable to the remaining term of the Notes to be redeemed (assuming that such Notes matured on the Par Call Date) (the “Remaining Life”) 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 Life. 
 “Comparable
Treasury Price” means, 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 Trustee obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 

“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. 
 “Make-Whole Premium” means the excess, if any, of: 

 

	 	•	 	the sum of the present values of the remaining scheduled payments of principal and interest thereon that would be due if the Notes matured on the Par Call Date (exclusive of interest accrued to the Redemption Date),
determined by discounting to the Redemption Date, on a semiannual basis, such principal and interest at the Treasury Rate plus 15 basis points; over 

  

	 	•	 	the principal amount of such Notes to be redeemed. 

 “Par Call Date” means

(USA) Inc. and Wells Fargo Securities, LLC and their successors; and (ii) two other firms that are primary U.S. Government securities dealers (each a “Primary Treasury Dealer”) which the Company specifies from time to time;
provided, however, that if any of them ceases to be a Primary Treasury Dealer, the Company shall substitute 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.,
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 Notes 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 on the third business day preceding the Redemption Date. 

If notice of redemption has been given as provided in the Base Indenture and funds for the redemption of any Notes called for redemption shall
have been made available on the Redemption Date referred to in such notice, such Notes shall cease to bear interest on the Redemption Date and the only right of the Holders of the Notes from and after the Redemption Date shall be to receive payment
of the Redemption Price upon surrender of such Notes in accordance with such notice. 
 6.    The Notes shall not provide for any
sinking fund or analogous provision. None of the Notes shall be redeemable at the option of the Holder.

issuable in book-entry form only, in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

principal amount of, and the Make-Whole Premium, if any, on, the Notes shall be payable upon declaration of acceleration pursuant to Section 502 of the Base Indenture. 

9.    The Notes shall be denominated in and principal of or interest on the Notes (or Redemption Price) shall be payable in such coin or
currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

10.    Except as provided in paragraph 5 of this Officers’ Certificate, the amount of payments of principal of or interest on the
Notes (or Redemption Price) shall not be determined with reference to an index or formula. 
 11.    Except as set forth herein, in the
Indenture or in the Notes, none of the principal of or interest on the Notes (or Redemption Price) shall be payable at the election of the Company or a Holder thereof in a currency or currencies, currency unit or units or composite currency or
currencies other than that in which the Notes are denominated or stated to be payable.
