 Discontinuance of Quotation; Alteration of Manner of Quotation 

If the quotation source for a Basket Component discontinues quoting the Settlement Price for such Basket Component as provided
herein and another entity publishes a quotation that the Calculation Agent determines, in its sole discretion, to be comparable to the discontinued quotation, then any subsequent Settlement Price will be determined by reference to the quotation of
such Settlement Price provided by such successor entity (in any such case, referred to herein as a “Successor Quotation Source”) on the date that the Settlement Price is to be determined. 

Upon any selection by the Calculation Agent of a Successor Quotation Source, the Company will cause notice to be given to the
Holder of this Security. 
 If the quotation source for a Basket Component discontinues quoting the Settlement Price for
such Basket Component as provided herein and the Calculation Agent determines that no Successor Quotation Source for such Settlement Price is available at such time, then any subsequent Settlement Price will be determined by reference to the
Calculation Agent’s good faith estimate of the Settlement Price for such Basket Component. 
 If a Successor Quotation
Source is selected or the Calculation Agent calculates a Settlement Price in the absence of a Successor Quotation Source, such Successor Quotation Source or Settlement Price will be used for all purposes with respect to calculation of the Redemption
Amount, including for purposes of determining whether a Market Disruption Event exists. 
 If the method of quoting a
Settlement Price as provided herein is changed in a material respect by a quotation source or a Successor Quotation Source, then the Calculation Agent will, on the date that the Settlement Price is to be determined, make such calculations and
adjustments as, in the good faith judgment of the Calculation Agent, may be necessary in order to arrive at a Settlement Price for such Basket Component as if such changes had not been made. The Calculation Agent will calculate the Redemption Amount
with reference to the Settlement Price, as adjusted. 
 Calculation Agent 

The Calculation Agent will determine the Redemption Amount and the Ending Level. In addition, the Calculation Agent will
(i) determine if adjustments are required to the Settlement Price of a Basket Component under the circumstances described in this Security, (ii) if a quotation source for a commodity discontinues quoting the Settlement Price for such
commodity, select a Successor Quotation Source or, if no Successor Quotation Source is available, determine the Settlement Price of such Basket Component, and (iii) determine whether a Market Disruption Event has occurred. 

The Company covenants that, so long as this Security is Outstanding, there shall at all times be a Calculation Agent (which
shall be a broker-dealer, bank or other financial institution) with respect to this Security. 

All determinations made by the Calculation Agent with respect to this Security will be at the sole discretion of the
Calculation Agent and, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and the Holder of this Security. All percentages and other 

  
 6 

 
amounts resulting from any calculation with respect to this Security will be rounded at the Calculation Agent’s discretion. 

Tax Considerations 

The Company agrees, and by acceptance of a beneficial ownership interest in this Security each Holder of this Security will be
deemed to have agreed (in the absence of a statutory, regulatory, administrative or judicial ruling to the contrary), for United States federal income tax purposes to characterize and treat this Security as a pre-paid derivative contract in respect
of the Basket. 
 Redemption and Repayment 

This Security is not subject to redemption at the option of the Company or repayment at the option of the Holder hereof prior
to September 18, 2017. This Security is not entitled to any sinking fund. 
 Acceleration 

If an Event of Default, as defined in the Indenture, with respect to this Security shall occur and be continuing, the
Redemption Amount (calculated as set forth in the next sentence) of this Security may be declared due and payable in the manner and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted
under the Indenture will be equal to the Redemption Amount hereof calculated as provided herein as though the date of acceleration was the Calculation Day. 
  

 

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.

WELLS FARGO & COMPANY 

MEDIUM-TERM NOTE, SERIES K 

Due Nine Months or More From Date of Issue 

Securities Linked to a Commodity Basket 

due September 18, 2017 

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 July 21, 1999, 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 K, of the Company, which series is limited to an aggregate principal amount or face amount, as applicable, of $25,000,000,000 or the equivalent thereof in one or more
foreign or composite currencies. The amount payable on the Securities of this series may be determined by reference to the performance of one or more equity-, commodity- or currency-based indices, exchange traded funds, securities, commodities,
currencies, statistical measures of economic or financial performance, or a basket comprised of two or more of the foregoing, or any other market measure or may bear interest at a fixed rate or a floating rate. The Securities of this series may
mature at different times, be redeemable at different times or not at all, be repayable at the option of the Holder at different times or not at all and be denominated in different currencies. 

Article Sixteen of the Indenture shall not apply to this Security. 

The Securities are issuable only in registered form without coupons and will be either
(a) book-entry securities represented by one or more Global Securities recorded in the book-entry system maintained by the Depositary or (b) certificated
securities issued to and registered in the names of, the beneficial owners or their nominees. 
 The Company agrees, to the
extent permitted by law, not to voluntarily claim the benefits of any laws concerning usurious rates of interest against a Holder of this Security. 

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 

  
 9 

 
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. Solely for the purpose of determining whether any consent, waiver, notice or other action or Act to be taken or given by the Holders of Securities pursuant to the Indenture has been given or taken by the Holders of Outstanding Securities in
the requisite aggregate principal amount, the principal amount of this Security will be deemed to be equal to the amount set forth on the face hereof as the “Face Amount” hereof. 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 

Section 403 and Article Fifteen of the Indenture and the provisions of clause (ii) of Section 401(1)(B) of the
Indenture, relating to 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,
shall not apply to this Security. The remaining provisions of Section 401 of the Indenture shall apply to this Security. 
 Authorized
Denominations 
 This Security is issuable only in registered form without coupons in denominations of $1,000 or any
amount in excess thereof which is an integral multiple of $1,000. 
 Registration of Transfer 

Upon due presentment for registration of transfer of this Security at the office or agency of the Company in the City of
Minneapolis, Minnesota, a new Security or Securities of this series, with the same terms as this Security, in authorized denominations for an equal aggregate Face Amount will be issued to the transferee in exchange herefor, as provided in the
Indenture and subject to the limitations provided therein and to the limitations described below, without charge except for any tax or other governmental charge imposed in connection therewith. 

This Security is exchangeable for definitive Securities in registered form only if (x) the Depositary notifies the
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 successor depositary is not
appointed within 90 days after the Company receives such notice or becomes aware of such ineligibility, (y) the Company in its sole discretion determines that this Security shall be exchangeable for definitive Securities in registered form
and notifies the Trustee thereof or (z) an Event of Default with respect to the Securities represented hereby has occurred and is continuing. If this Security is exchangeable pursuant to the preceding sentence, it shall be exchangeable for
definitive Securities in registered 

  
 10 

 
form, having the same date of issuance, Stated Maturity Date and other terms and of authorized denominations aggregating a like amount. 

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. 

Prior to due presentment of this Security for registration of transfer, 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. 
 Obligation of the Company Absolute

the Company, which is absolute and unconditional, to pay the Redemption Amount at the times, place and rate, and in the coin or currency, herein prescribed, except as otherwise provided in this Security. 

No Personal Recourse 

No recourse shall be had for the payment of the Redemption Amount, or for any claim based hereon, or otherwise in respect
hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or any successor corporation, whether by virtue of
any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture
unless otherwise defined in this Security.
