	 	(iv)	in the case of soybean futures, the official settlement price per bushel of deliverable-grade soybeans of the first nearby month futures contract (or, in the case of

The “Calculation Day” shall be April 17, 2017. If such day is not a Trading Day with respect to a Basket Component,
the Calculation Day for such a Basket Component will be postponed to the next succeeding day that is a Trading Day with respect to such Basket Component. The Calculation Day is subject to postponement due to the occurrence of a Market Disruption
Event. If a Market Disruption Event occurs or is continuing with respect to a Basket Component on the Calculation Day, the Calculation Day for such Basket Component will be postponed to the first succeeding Trading Day for such Basket Component on
which a Market Disruption Event for such Basket Component has not occurred and is not continuing. If such first succeeding Trading Day has not occurred as of the fifth scheduled Trading Day after the scheduled Calculation Day for such Basket
Component, that fifth scheduled Trading Day shall be deemed the Calculation Day. If the Calculation Day has been postponed five scheduled Trading Days for such Basket Component after the scheduled Calculation Day for such Basket Component and such
fifth scheduled Trading Day is not a Trading Day, or if a Market Disruption Event occurs or is continuing with respect to the Basket Component on such fifth scheduled Trading Day, the Calculation Agent will determine its good faith estimate of the
Settlement Price of such Basket Component on such fifth scheduled Trading Day. Notwithstanding a postponement of a Calculation Day for a particular Basket Component due to a non-Trading Day or Market Disruption Event with respect to such Basket
Component, the originally scheduled Calculation Day will remain the Calculation Day for any Basket Component not affected by a non-Trading Day or Market Disruption Event. See “—Market Disruption Events.” 

“Calculation Agent Agreement” shall mean the Calculation Agent Agreement dated as of April 24, 2012 between the
Company and the Calculation Agent, as amended from time to time.

 “Calculation Agent” shall mean the Person that has entered into the
Calculation Agent Agreement with the Company providing for, among other things, the determination of the Ending Level and the Redemption Amount, which term shall, unless the context otherwise requires, include its successors under such Calculation
Agent Agreement. The initial Calculation Agent shall be Wells Fargo Securities, LLC. Pursuant to the Calculation Agent Agreement, the Company may appoint a different Calculation Agent from time to time after the initial issuance of this Security
without the consent of the Holder of this Security and without notifying the Holder of this Security. 
 Market Disruption Events

 A “Market Disruption Event” means any of the following events as determined by the Calculation Agent
in its sole discretion: 
  

	(i)	with respect to crude oil futures: (A) a material limitation or suspension of trading in the first nearby month futures contract for ICE Brent crude oil traded on
the ICE; or (B) the failure of the ICE to announce the ICE Brent crude price; 

  

	(ii)	with respect to gasoline futures: (A) a material limitation or suspension of trading in the first nearby month futures contract for NYMEX RBOB gasoline traded on
NYMEX; or (B) the failure of NYMEX to announce the NYMEX RBOB gasoline price; 

  

	(iii)	with respect to corn futures: (A) a material limitation or suspension of trading in the applicable futures contract for deliverable-grade corn; or (B) the
failure of the CBOT to announce the CBOT corn price; 

  

	(iv)	with respect to soybean futures: (A) a material limitation or suspension of trading in the applicable futures contract for deliverable-grade soybeans; or
(B) the failure of the CBOT to announce the CBOT soybean price; 

  

	(v)	with respect to copper: (A) a material limitation or suspension of trading in copper Grade A on the LME; or (B) the failure of the LME to announce the LME
copper Grade A price; and 

  

	(vi)	with respect to nickel: (A) a material limitation or suspension of trading in Primary Nickel on the LME; or (B) the failure of the LME to announce the LME
Primary Nickel price. 

 For purposes of determining whether a Market Disruption Event has occurred or is continuing with respect
to a Basket Component, a limitation on the hours or number of days of trading will not constitute a Market Disruption Event if it results from an announced change in the regular business hours of the relevant trading facility. 

Discontinuance of Quotation; Alteration of Manner of Quotation 
 If the quotation source for a commodity discontinues quoting the Settlement Price for such commodity 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 

  
 5 








 
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 commodity discontinues quoting the Settlement Price for such commodity 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 commodity. 

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 commodity 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 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
April 24, 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; provided, however, if such date is not a Trading Day or if a Market Disruption Event has occurred or is
continuing on that day, the Calculation Day will be postponed as provided herein. 
  

 
 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 
 Notes Linked to a Commodity Basket 
 due April 24, 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.

Section 401 of the Indenture shall apply to this Security.

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

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.

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.
