Due Nine Months or More From Date of Issue 

Notes Linked to 3 Month LIBOR due March 26, 2020 

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 March 26, 2020 (the “Stated Maturity Date”) and to pay interest thereon from March 26, 2015 or from the most recent Interest Payment Date to which
interest has been paid or duly provided for quarterly on each March 26, June 26, September 26 and December 26, commencing June 26, 2015 and at Maturity (each, an “Interest Payment Date”), at the rate per
annum specified below 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 for such interest next preceding such Interest Payment Date. The Regular Record Date for an Interest Payment Date
shall be one 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. “Business Day” shall mean a 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 in New York, New York and (ii) that is also a London Banking Day (as defined below). 

Except as described below for the first Interest Period, on each Interest Payment Date, interest will be paid for the period
commencing on and including the immediately preceding 







 
Interest Payment Date and ending on and including the day immediately preceding that Interest Payment Date. This period is referred to as an “Interest Period.” The first Interest
Period will commence on and include March 26, 2015 and end on and include June 25, 2015. Interest on this Security will be computed on the basis of a 360-day year of twelve 30-day months. 
 The interest rate on this Security that will apply during the first four
Interest Periods (up to and including the Interest Period ending March 25, 2016) will be equal to 1.30% per annum. For all Interest Periods commencing on or after March 26, 2016, the interest rate on this Security will be determined
by the calculation agent for this Security (the “Calculation Agent”) and will be equal to 3 month LIBOR on the Determination Date for such Interest Period plus 0.40%, but in no event will such rate be more than the Maximum Interest
Rate or less than the Minimum Interest Rate. 
 The “Determination Date” for an Interest Period commencing
on or after March 26, 2016 will be two London Banking Days prior to the first day of such Interest Period. A “London Banking Day” is any day on which commercial banks and foreign exchange markets settle payments in London. 

“3 month LIBOR” means, for any Determination Date, the arithmetic mean of the offered rates for deposits in
U.S. dollars having a 3 month maturity, commencing on the second London Banking Day immediately following that Determination Date that appear on the Designated LIBOR Page as of 11:00 a.m., London time, on that Determination Date, if at
least two offered rates appear on the Designated LIBOR Page, provided that if the Designated LIBOR Page by its terms provides only for a single rate, that single rate will be used. The “Designated LIBOR Page” means the display on
Reuters, 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 U.S. dollars. 

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 U.S. dollars for a 3 month period commencing on the second London Banking Day immediately following that Determination Date to prime banks in the London Interbank market at approximately 11:00 a.m., London time,
on that Determination Date and in a principal amount that is representative of a single transaction in U.S. dollars in that market at that time. If at least two quotations are provided, 3 month LIBOR determined on that Determination Date will
be the arithmetic mean of those quotations. 
 If fewer than two quotations are provided, 3 month LIBOR will be the
arithmetic mean of the rates quoted at approximately 11:00 a.m. in New York, New York on that Determination Date by three major banks in New York, New York selected by the Calculation Agent for loans in U.S. dollars to leading European banks,
having a 3 month maturity and in a principal amount that is representative of a single transaction in U.S. dollars in that market at that time. 

  
 2 








 If the banks so selected by the Calculation Agent are not quoting as set forth
above, 3 month LIBOR on such Determination Date will be determined by the Calculation Agent in a commercially reasonable manner. 

The “Maximum Interest Rate” applicable to an Interest Period commencing on or after March 26, 2016 is
4.00% per annum. 
 The “Minimum Interest Rate” applicable to an Interest Period commencing on or
after March 26, 2016 is 0.00% per annum. 
 The Calculation Agent shall, upon the request of a Holder of this Security,
provide the interest rate then in effect and, if determined, the interest rate that will become effective for the next Interest Period. All calculations of the Calculation Agent, in the absence of manifest error, shall be conclusive for all purposes
and binding on the Company and the Holder hereof. The Calculation Agent shall notify the Paying Agent of each determination of the interest applicable to this Security promptly after the determination is made. Wells Fargo Securities, LLC will
initially act as Calculation Agent. The Company may appoint a successor Calculation Agent with the written consent of the Trustee. 

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 will be made in immediately available funds at the office or agency of the Company
maintained for that purpose in the City of Minneapolis, Minnesota 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; provided, however, that, at the option of
the Company, payment of interest may 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.
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. 

This Security is not subject to redemption at the option of the Company or repayment at the option of the Holder hereof prior
to March 26, 2020. This Security is not entitled to any sinking fund.

 Reference is hereby made to the further provisions of this Security set forth on

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.
