 WELLS FARGO & COMPANY, a corporation duly organized and existing
under the laws of the State of Delaware (hereinafter called the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or
registered assigns, the principal sum of
                                         
        DOLLARS ($                    ) on the Stated Maturity Date shown above (except to the extent
redeemed prior to such date) and to pay interest, if any, on the principal amount hereof, (i) from the Original Issue Date specified above or from the most recent Fixed Rate Interest Payment Date to which interest has been paid or duly provided
for to, but excluding, April 4, 2030 at the rate per annum of 4.478% on the Fixed Rate Interest Payment Dates specified above, and (ii) if this Security has not been previously redeemed, from, and including April 4, 2030 or from the
most recent Floating Rate Interest Payment Date to which interest has been paid or duly provided for to, but excluding, the date of Maturity on the Floating Rate Interest Payment Dates specified above at the Base Rate plus the Spread specified
above, as determined by the Calculation Agent in accordance with the provisions on the reverse hereof under the headings “Determination of LIBOR” and “Effect of Benchmark Transition Event,” as applicable. The interest so payable,
and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the
Regular Record Date next preceding such Interest Payment Date. Interest payable upon Maturity will be paid to the Person to whom principal is payable. 

If a Fixed Rate Interest Payment Date is not a Business Day, interest on this Security shall be payable on the next day that
is a Business Day, with the same force and effect as if made on such Fixed Rate Interest Payment Date, and without any interest or other payment with respect to the delay. If a Floating Rate Interest Payment Date falls on a day that is not a
Business Day, other than a Floating Rate Interest Payment Date that is also the date of Maturity, such Floating Rate Interest Payment Date will be postponed to the following day that is a Business Day, except that, if such following Business Day is
in the next calendar month, such Floating Rate Interest Payment Date shall be the immediately preceding day that is a Business Day. If the date of Maturity would fall on a day that is not a Business Day, the payment of principal and interest shall
be made on the next Business Day, with the same force and effect as if made on the due date, and no additional interest shall accrue on the amount so payable for the period from and after such date of Maturity. For purposes of this Security,
“Business Day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in New York, New York and, for a Floating Rate
Interest Payment Date and any date of Maturity during the period from, and including, January 3, 2031 to, but excluding, the Stated Maturity Date, a day that is also a London Banking Day. For purposes of this Security, “London Banking
Day” means any day on which commercial banks and foreign exchange markets settle payments in London. 
 Interest
payments on this Security shall be the amount of interest accrued from and including the Original Issue Date specified above or from and including the last date to which interest has been paid, or provided for, as the case may be, to but excluding,
the following Interest Payment Date or the date of Maturity. This period is referred to as an “Interest Period.” If this Security has been issued upon transfer of, in exchange for, or in replacement of, a Predecessor Security, interest on
this Security shall accrue from the last Interest Payment Date to which interest was paid on such Predecessor Security or, if no interest was paid on such 

  
 3 













 
Predecessor Security, from the Original Issue Date specified above. The first payment of interest on a Security originally issued and dated between a Regular Record Date specified above and an
Interest Payment Date will be due and payable on the Interest Payment Date following the next succeeding Regular Record Date to the registered owner on such next succeeding Regular Record Date. 

The principal and interest on this Security is payable by the Company in the Specified Currency specified above. 

Any interest not punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Regular Record
Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) 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,
notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on
which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. 

Payment of interest on this Security, other than payments of interest at Maturity, will be paid by check mailed to the Person
entitled thereto at such Person’s last address as it appears in the Security Register or by wire transfer to such account as may have been designated by such Person. Any such designation for wire transfer purposes shall be made by providing
written notice to the Paying Agent not later than 10 calendar days prior to the applicable Interest Payment Date. Payment of principal of and interest on this Security at Maturity will be made against presentation of this Security at the office or
agency of the Company maintained for that purpose in the City of Minneapolis, Minnesota. Notwithstanding the foregoing, for so long as this Security is a Global Security registered in the name of the Depositary, payments of principal and interest on
this Security will be made to the Depositary by wire transfer of immediately available funds. 
 The Company will pay any
administrative costs imposed by banks on payors in making payments on this Security in immediately available funds and the Holder of this Security will pay any administrative costs imposed by banks on payees in connection with such payments. Any
tax, assessment or governmental charge imposed upon payments on this Security will be borne by the Holder of this Security. 

Reference is hereby made to the further provisions of this Security 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 referred to on the reverse hereof by manual signature or its duly authorized agent under the Indenture referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

 [Reverse of Note] 

WELLS FARGO & COMPANY 

MEDIUM-TERM NOTE, SERIES U 

SENIOR REDEEMABLE FIXED-TO-FLOATING RATE NOTES 

General 
 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 February 21, 2017, as amended or supplemented from time to
time (herein called the “Indenture”), between the Company and Citibank, 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 of the Securities designated as Medium-Term Notes, Series U, of the Company. The Securities of this series may mature at different times, bear
interest, if any, at different rates, be redeemable at different times or not at all, be repayable at the option of the Holder at different times or not at all, be issued at an original issue discount and be denominated in different currencies. 

The Securities are issuable only in registered form without coupons and will be
book-entry securities represented by one or more global securities recorded in the book-entry system maintained by the Depositary (“Global Securities”). 

Interest Rate Reset 

The interest rate in effect for the Fixed Rate Period shall be the Initial Interest Rate specified on the face hereof. The
interest rate in effect for the Floating Rate Period shall be the Base Rate plus the Spread specified on the face hereof, subject to modification as provided herein. Commencing with the Initial Interest Reset Date specified on the face hereof
following the Original Issue Date specified on the face hereof, the interest rate on this Security will be reset quarterly as specified on the face hereof under “Interest Reset Period.” Each such adjusted rate shall be applicable from, and
including, the Interest Reset Date to which it relates to, but not including, the next succeeding Interest Reset Date or until Maturity, as the case may be. On each Interest Reset Date, the rate of interest on this Security shall be the rate
determined with respect to the Interest Determination Date next preceding such Interest Reset Date in accordance with the provisions below and adjusted by the addition of the Spread specified on the face hereof. 

If any Interest Reset Date would otherwise be a day that is not a Business Day, such Interest Reset Date will be postponed to
the following Business Day, except that if such following Business Day is in the next calendar month, such Interest Reset Date shall be the immediately preceding Business Day. 

  
 6 













 The amount of interest to be paid on this Security for each Interest Period
occurring during the Fixed Rate Period shall be computed on the basis of a 360-day year of twelve 30-day months. 

The amount of interest to be paid on this Security for each Interest Period occurring during the Floating Rate Period will be
calculated by multiplying the principal amount of this Security by an accrued interest factor. The “accrued interest factor” will be computed by adding the interest factors calculated for each day in such Interest Period. The
“interest factor” for each day is computed by dividing the interest rate applicable to that day by 360. 
 All
percentages resulting from any calculation referred to herein shall be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001% and all U.S. dollar amounts used in or resulting from
any of the above calculations will be rounded, if necessary, to the nearest cent, with one-half cent rounded upward. All U.S. Dollar amounts used in or resulting from these calculations will be rounded to
the nearest two decimal places, with 0.005 round up to 0.01. 
 The Calculation Agent shall calculate the interest rate
hereon in accordance with the foregoing on or before each Calculation Date. 
 The interest rate on this Security shall in
no event be higher than the maximum rate permitted by New York law, as the same may be modified by United States law of general application. 

At the request of the Holder hereof, the Calculation Agent shall provide to the Holder hereof the interest rate hereon then
in effect and, if determined, the interest rate that will become effective on the next Interest Reset Date with respect to this Security. The Calculation Agent’s determination of any interest rate shall be final and binding in the absence of
manifest error. The Calculation Agent shall notify the Paying Agent of each determination of the interest applicable to this Security promptly after the determination is made. 

A “Calculation Date”, where applicable, for any Interest Determination Date will be the earlier of: 

 

	 	•	 	 the tenth calendar day after that Interest Determination Date or, if that day is not a Business Day, the next
Business Day; or 


  

	 	•	 	 the Business Day immediately preceding the applicable Interest Payment Date or date of Maturity.



 Determination of LIBOR 

The Calculation Agent will determine the London Interbank Offered Rate (“LIBOR”) for each Interest Determination
Date as follows: 
  

	 	•	 	 “LIBOR” with respect to any Interest Determination Date specified on the face hereof shall equal the
arithmetic mean of the offered rates for deposits in the Index Currency having the Index Maturity designated on the face hereof, commencing on the second London Banking Day immediately following that Interest Determination Date that




  
 7 














	 	 
appear on the Designated LIBOR Page as of 11:00 a.m., London time, on that Interest Determination Date, if at least two offered rates appear on the Designated LIBOR Page, provided that if the
specified Designated LIBOR Page by its terms provides only for a single rate, that single rate will be used. 


  

	 	•	 	 If (i) fewer than two offered rates appear or (ii) no rate appears and the Designated LIBOR Page by
its terms provides only for a single rate, then the Calculation Agent will request the principal London offices of each of four major banks in the London Interbank market, as selected by the Calculation Agent, to provide the Calculation Agent with
its offered quotation for deposits in the Index Currency for the period of the Index Maturity specified on the face hereof commencing on the second London Banking Day immediately following the Interest Determination Date to prime banks in the London
Interbank market at approximately 11:00 a.m., London time, on that Interest Determination Date and in a principal amount that is representative of a single transaction in that Index Currency in that market at that time. 



 

	 	•	 	 If at least two quotations are provided, LIBOR determined on that Interest Determination Date will be the
arithmetic mean of those quotations. If fewer than two quotations are provided, LIBOR will be determined for the applicable Interest Reset Date as the arithmetic mean of the rates quoted at approximately 11:00 a.m., or some other time specified on
the face hereof, in the applicable principal financial center for the country of the Index Currency on that Interest Determination Date, by three major banks in that principal financial center selected by the Calculation Agent for loans in the Index
Currency to leading European banks, having the Index Maturity specified on the face hereof and in a principal amount that is representative of a single transaction in that Index Currency in that market at that time. 



 

	 	•	 	 If the banks so selected by the Calculation Agent are not quoting as set forth above, LIBOR for that Interest
Determination Date will remain LIBOR for the immediately preceding Interest Reset Period, or, if none, the rate of interest payable will be the Initial Interest Rate. 



The “Index Currency” means the currency specified on the face hereof as the currency for which LIBOR will be
calculated. 
 “Designated LIBOR Page” means the display on Thomson Reuters Eikon Service, or any successor
service, on page LIBOR01, or any other page as may replace that page on that service, for the purpose of displaying the London Interbank rates for the applicable Index Currency. 

Effect of Benchmark Transition Event 

Upon the occurrence of a Benchmark Transition Event (as defined below) and its related Benchmark Replacement Date (as defined
below), the following terms will apply to this Security solely in respect of determinations, decisions, elections, calculations and adjustments to be made in respect of the Floating Rate Period. References in this section entitled “Effect of
Benchmark Transition Event” to “its designee” refer to the Calculation Agent to be appointed by the Company. 

  
 8 













 Benchmark Replacement 

If the Company or its designee determines that a Benchmark Transition Event and its related Benchmark Replacement Date have
occurred prior to the Reference Time (as defined below) in respect of any determination of the Benchmark (as defined below) on any date, the Benchmark Replacement (as defined below) will replace the then-current Benchmark for all purposes relating
to this Security in respect of such determination on such date and all determinations on all subsequent dates. 

Benchmark Replacement Conforming Changes 

In connection with the implementation of a Benchmark Replacement, the Company or its designee will have the right to make
Benchmark Replacement Conforming Changes (as defined below) from time to time. 
 Decisions and Determinations 

Any determination, decision, election or calculation that may be made by the Company or its designee pursuant to this section
entitled “Effect of Benchmark Transition Event,” including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and
any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error, may be made in the Company’s or its designee’s sole discretion, and, notwithstanding anything to the contrary
herein relating to this Security, shall become effective without consent from any other party. 
 For the avoidance of
doubt, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, interest payable on this Security for the Floating Rate Period will be an annual rate equal to the sum of the applicable Benchmark Replacement and
the Spread specified on the face hereof. 
 Definitions 

As used in this section entitled “Effect of Benchmark Transition Event”: 

“Benchmark” means, initially, three-month LIBOR; provided that if a Benchmark Transition Event and its
related Benchmark Replacement Date have occurred with respect to three-month LIBOR or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement. 

“Benchmark Replacement” means the Interpolated Benchmark with respect to the then-current Benchmark, plus the
Benchmark Replacement Adjustment for such Benchmark; provided that if the Company or its designee cannot determine the Interpolated Benchmark as of the Benchmark Replacement Date, then “Benchmark Replacement” means the first
alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date: 

  
 9 














	 	(1)	 the sum of: (a) Term SOFR and (b) the Benchmark Replacement Adjustment; 



 

	 	(2)	 the sum of: (a) Compounded SOFR and (b) the Benchmark Replacement Adjustment;



  

	 	(3)	 the sum of: (a) the alternate rate of interest that has been selected or recommended by the Relevant
Governmental Body as the replacement for the then-current Benchmark for the applicable Corresponding Tenor and (b) the Benchmark Replacement Adjustment; 



 

	 	(4)	 the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment;



  

	 	(5)	 the sum of: (a) an alternate rate of interest that has been selected by the Company or its designee as
the replacement for the then-current Benchmark for the applicable Corresponding Tenor that gives due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate
notes at such time and (b) the Benchmark Replacement Adjustment. 


 “Benchmark Replacement
Adjustment” means the first alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date: 
  

	 	(1)	 the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a
positive or negative value or zero) that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement; 



 

	 	(2)	 if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA
Fallback Adjustment; 


  

	 	(3)	 the spread adjustment (which may be a positive or negative value or zero) that has been selected by the
Company or its designee giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark
Replacement for U.S. dollar denominated floating rate notes at such time. 


 “Benchmark Replacement
Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definitions of Interest Reset Period and Interest Reset Date, timing and frequency of
determining rates and making payments of interest, rounding of amounts or tenors, changes to the definition of “Corresponding Tenor” solely when such tenor is longer than the Interest Reset Period and other administrative matters) that the
Company or its designee decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its designee decides that adoption of any portion of such
market practice is not administratively feasible or if the Company or its designee determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee determines is reasonably
necessary). 

  
 10 













 “Benchmark Replacement Date” means the earliest to
occur of the following events with respect to the then-current Benchmark: 
  

	 	(1)	 in the case of clause (1) or (2) of the definition of “Benchmark Transition Event,” the later
of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark; or 



 

	 	(2)	 in the case of clause (3) of the definition of “Benchmark Transition Event,” the date of the
public statement or publication of information referenced therein. 


 For the avoidance of doubt, if the event giving rise
to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

 “Benchmark Transition Event” means the occurrence of one or more of the following events with respect
to the then-current Benchmark: 
  

	 	(1)	 a public statement or publication of information by or on behalf of the administrator of the Benchmark

the Benchmark; 


  

	 	(2)	 a public statement or publication of information by the regulatory supervisor for the administrator of the
Benchmark, the central bank for the currency of the Benchmark, an insolvency official with jurisdiction over the administrator for the Benchmark, a resolution authority with jurisdiction over the administrator for the Benchmark or a court or an
entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark has ceased or will cease to provide the Benchmark permanently or indefinitely, provided
that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark; or 


  

	 	(3)	 a public statement or publication of information by the regulatory supervisor for the administrator of the
Benchmark announcing that the Benchmark is no longer representative. 


 “Compounded SOFR” means
the compounded average of SOFRs for the applicable Corresponding Tenor, with the rate, or methodology for this rate, and conventions for this rate (which will be compounded in arrears with a lookback and/or suspension period as a mechanism to

 11 














	 	(1)	 the rate, or methodology for this rate and conventions for this rate selected or recommended by the Relevant
Governmental Body for determining compounded SOFR; provided that: 


  

	 	(2)	 if, and to the extent that, the Company or its designee determines that Compounded SOFR cannot be determined
in accordance with clause (1) above, then the rate, or methodology for this rate, and conventions for this rate that have been selected by the Company or its designee giving due consideration to any industry-accepted market practice for U.S.
dollar denominated floating rate notes at such time. 


 “Corresponding Tenor” with respect to a
Benchmark Replacement means a tenor (including overnight) having approximately the same length (disregarding business day adjustment) as the applicable tenor for the then-current Benchmark. 

“Federal Reserve Bank of New York’s Website” means the website of the Federal Reserve Bank of New York at
http://www.newyorkfed.org, or any successor source. 
 “Interpolated Benchmark” with respect to the Benchmark
means the rate determined for the Corresponding Tenor by interpolating on a linear basis between: (1) the Benchmark for the longest period (for which the Benchmark is available) that is shorter than the Corresponding Tenor and (2) the
Benchmark for the shortest period (for which the Benchmark is available) that is longer than the Corresponding Tenor. 

“ISDA Definitions” means the 2006 ISDA Definitions published by the International Swaps and
Derivatives Association, Inc. (“ISDA”) or any successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time.

zero) that would apply for derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor. 

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions
to be effective upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment.

LIBOR, 11:00 a.m. (London time) on the day that is two London Banking Days preceding the date of such determination, and (2) if the Benchmark is not three-month LIBOR, the time determined by the Company or its designee in accordance with the
Benchmark Replacement Conforming Changes. 

  
 12

Securities at the time Outstanding of all series to be affected, acting together as a class; provided, however, that amendments or modifications to this Security contemplated by the provisions set forth in the section entitled “Effect of
Benchmark Transition Event” shall not require the consent of the Holder of this Security. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities of all series at the time Outstanding
affected by certain provisions of the Indenture, acting together as a class, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with those provisions of the Indenture. Certain past defaults under the
Indenture and their consequences may be waived under the Indenture by the Holders of a majority in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series. 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. 
 Defeasance and Covenant Defeasance

 Redemption 

This Security is redeemable at the option of the Company. The Company may redeem this Security, in whole at any time or in
part from time to time on any day included in the Make-Whole Redemption Period (as defined below), at a redemption price equal to the sum of: (i) 100% of the principal amount of this Security being redeemed plus accrued and unpaid interest
thereon, to, but excluding, the date of such redemption (the “Make-Whole Redemption Date”) and (ii) the Make-Whole Amount (as defined below). The redemption price will be calculated by the Company or by a Person designated by the
Company on the Company’s behalf. 
 “Make-Whole Amount” means the excess, if any, of: (i) the aggregate
present value as of the Make-Whole Redemption Date of each dollar of principal being redeemed and the amount of interest (exclusive of interest accrued to the Make-Whole Redemption Date) that would have been payable in respect of each such dollar if
such redemption had been made on the final day of the Make-Whole Redemption Period, determined by discounting, on a semi-annual basis, such principal and interest at the Reinvestment Rate (as defined below) (determined on the third Business Day
preceding the date notice of such redemption is given) from the respective dates on which such principal and interest would have been payable if such redemption had been made on the final day of the Make-Whole Redemption Period over (ii) the
aggregate principal of this Security being redeemed. 
 “Reinvestment Rate” means the yield on Treasury
securities at a constant maturity corresponding to the remaining life (as of the Make-Whole Redemption Date and rounded to the nearest month) to the Stated Maturity Date specified above (the “Treasury Yield”), plus the Make-Whole Spread.
For purposes hereof, the Treasury Yield shall be equal to the arithmetic mean of the yields published in the Statistical Release (as defined below) under the heading which represents the average for the immediately preceding week for “U.S.
Government Securities—Treasury Constant Maturities” with a maturity equal to such remaining life; provided that if no published maturity exactly corresponds to such remaining life, then the Treasury Yield shall be
interpolated or extrapolated on a straight-line basis from the arithmetic means of the yields for the next shortest and next longest published maturities. For purposes of calculating the Reinvestment Rate, the most recent Statistical Release
published prior to the date of determination of the Make-Whole Amount shall be used. If the format or content of the Statistical Release changes in a manner that precludes determination of the Treasury Yield in the above manner, then the Treasury
Yield shall be determined in the manner that most closely approximates the above manner, as reasonably determined by the Company. 

“Statistical Release” means the Data Download Program designated as “H.15” or any successor publication
which is published weekly by the Board of Governors of the Federal Reserve System and which reports yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at
the time of any determination, then such other reasonable comparable index which shall be designated by the Company. 
 The
“Make-Whole Redemption Period” is the period commencing on and including April 6, 2021 and ending on and including April 3, 2030. 

  
 14 













 The “Make-Whole Spread” is 0.50%. 

This Security is also redeemable by the Company (i) in whole, but not in part, on April 4, 2030 or (ii) in
whole at any time or in part from time to time, on or after January 3, 2031, in each case at a redemption price equal to 100% of the principal amount of this Security being redeemed plus accrued and unpaid interest thereon to, but excluding,
the date of such redemption. 
 The Company may exercise its options to redeem this Security by mailing a notice by
first-class mail, postage prepaid, of such redemption to each Holder of the Securities of this series to be redeemed or, in the case of Global Securities, the Company shall provide such notice to the Depositary, as holder of the Global Securities
pursuant to the applicable procedures of such Depositary, at least 15 days and not more than 60 days prior to the applicable Redemption Date. Unless the Company defaults in the payment of the Redemption Price, on and after the applicable
Redemption Date interest will cease to accrue on this Security or portion hereof called for redemption. 
 Repayment 

This Security will not be repayable prior to the Stated Maturity Date at the option of the Holder.

Company that it is unwilling or unable to continue as Depositary for this Security or if at any time the Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and a qualified successor depositary

This Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of
the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor of the Depositary or a nominee of such successor. Except as provided above, owners of beneficial interests in this Global
Security will not be entitled to receive physical delivery of Securities in definitive form and will not be considered the Holders hereof for any purpose under the Indenture.
