 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
                                    , or registered assigns,
the principal sum of                                     
(                        ) on the Stated Maturity Date shown above (except to the extent redeemed, repaid, renewed or
extended prior to such date) and to pay interest, if any, on the principal amount hereof from the Original Issue Date or from the most recent Interest Payment Date to which interest has been paid or duly provided for on each Interest Payment Date
set forth above, commencing on the Initial Interest Payment Date shown above, and at Maturity at the Interest Rate shown above (computed on the basis of a 360-day year of twelve 30-day months) until the principal hereof is paid or made available for
payment. 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. The Regular Record Date for an Interest Payment Date shall be the
fifteenth calendar day, whether or not a Business Day, prior to such Interest Payment Date. 
 If an 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 Interest Payment Date, and without any interest or other payment with respect to the delay.
If the date of Maturity would fall on a day that is not a Business Day, the payment of principal and any premium 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, (i) that is neither a legal holiday nor
a day on which banking institutions are authorized or required by law or regulation to close (a) in New York, New York, (b) if this Security is denominated in a Specified Currency other than U.S. dollars, euro or Australian dollars, in the
principal financial center of the country of the Specified Currency or (c) if this Security is denominated in Australian dollars, in Sydney, Australia and (ii) if this Security is denominated in euro, that is also a TARGET Settlement Day.
For purposes of this Security, “TARGET Settlement Day” means any day on which the Trans-European Automated Real-time Gross Settlement Express Transfer System is open. 

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 

  
 2 








 
paid, or provided for, as the case may be, to but excluding, the following Interest Payment Date or the date of Maturity. 

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 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. 
 Notwithstanding the foregoing, if an Addendum is attached hereto or
“Other/Additional Terms” apply to this Security as specified above, this Security shall be subject to the terms set forth in such Addendum or such “Other/Additional Terms.” 

The principal (and premium, if any) 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.

 [Reverse of Note] 

WELLS FARGO & COMPANY 

SUBORDINATED MEDIUM-TERM FIXED RATE NOTE, SERIES O 

Due Nine Months or More From Date of Issue 

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 August 30, 1999, as amended or supplemented from time to
time (herein called the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, National Association (successor in interest to The First National Bank of Chicago), 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 Subordinated Medium-Term
Notes, Series O, 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”). 

The indebtedness evidenced by this Security is, to the extent and in the manner set forth in the Indenture, subordinate and
subject in right of payment to the prior payment in full of the principal of and premium, if any, and interest on all Senior Debt of the Company, and the Holder of this Security, by accepting the same, agrees to and shall be bound by the provisions
of the Indenture with respect thereto. 
 Events of Default 

If an Event of Default, as defined in the Indenture, 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. 

  
 6 








 Modification and Waivers 

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 all series to be affected, acting together as a class. 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 

The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness on this Security and
(b) certain restrictive covenants and certain Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Security. 

Redemption 
 If so
provided on the face hereof, the Company may at its option redeem this Security in whole or in part in increments of $1,000 or the equivalent amount in a foreign or composite currency (provided that any remaining principal amount of this Security
shall not be less than the minimum authorized denomination hereof) on or after the date or dates designated as the Redemption Date(s) on the face hereof at 100% of the unpaid principal amount hereof or the portion thereof redeemed, together with
accrued interest, if any, to the Redemption Date or, if a Redemption Price other than 100% of the principal amount to be redeemed is specified on the face hereof, the Redemption Price specified in the Addendum attached hereto. The Company may
exercise such option by mailing a notice of such redemption to each Holder of the Securities of this series to be redeemed by first-class mail, postage prepaid, at least 30 days and not more than 60 days prior to the applicable Redemption Date.
In the event of redemption of this Security in part only, the Company shall issue a new Security or Securities for the unredeemed portion hereof in the name of the Holder hereof upon the cancellation hereof. If less than all of the Securities of
this series with like tenor and terms are to be redeemed, the Securities to be redeemed shall be selected by the Trustee by such method as the Trustee shall deem fair and appropriate and may provide for the selection for redemption of a portion of
the principal amount of the Securities of this series held by a Holder equal to an authorized denomination. If this Security is a Global Security and if less than all of the Securities of this series are to be redeemed, the redemption shall be made
in accordance with the Depositary’s customary procedures. 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

principal amount to be repaid, plus accrued interest, if any, to the Repayment Date or, if a Repayment Price other than 100% of the principal amount to be repaid is specified on the face hereof, at the Repayment Price specified in the Addendum
attached hereto. In order for this Security to be repaid, the Paying Agent must receive at least 30 days but not more than 45 days prior to the Optional Repayment Date (i) this Security with the form entitled “Option to Elect
