	 	(i)	the Minimum Return; and 

  

							
				
		 	 (ii)	  	

	  	; or

  

	 	•	 	 If the Average Ending Level is less than the Starting Level: the Face Amount plus the Minimum Return. 

“Basket” shall mean a basket comprised of the following Basket Components, with the return of each Basket Component
relative to the U.S. Dollar having the weighting in the Basket noted parenthetically: the Australian Dollar (33.4%); the Norwegian Krone (33.3%); and the Canadian Dollar (33.3%). 

“Basket Component” shall mean each of the Australian Dollar; the Norwegian Krone; and the Canadian Dollar. 

The “Pricing Date” shall mean February 29, 2012. 

The “Starting Level” is 100. 
 The “Average Ending Level” will be calculated based on the weighted returns of the Basket Components, each relative to the U.S. Dollar, and will be equal to the product of
(i) 100 and (ii) an amount equal to 1 plus the sum of: (A) 33.4% of the Average Component Return of the Australian Dollar; (B) 33.3% of the Average Component Return of the Norwegian Krone; and (C) 33.3% of the Average
Component Return of the Canadian Dollar. 
 The “Minimum Return” is 2% of the Face Amount. 

The “Average Component Return” of a Basket Component will be equal to: 

Average Component Level – Initial Component Level 
 Initial Component Level 
 where, 

 

	 	•	 	 the “Initial Component Level” is the Exchange Rate of such Basket Component on the Pricing Date; and 

 

	 	•	 	 the “Average Component Level” will be the arithmetic average of the Exchange Rate of such Basket Component on the Calculation Days.

  
 2 

 The Initial Component Levels of the Basket Components are as follows: Australian Dollar
(1.08045); Norwegian Krone (1.7993); and Canadian Dollar (1.01528). 
 The “Participation Rate” is 100%.

 The “Exchange Rate” for each Basket Component on any Currency Trading Day, for purposes of determining the
Average Component Return, will be determined as follows: 
  

	 	•	 	 Australian Dollar – the rate for conversion of Australian Dollars into U.S. Dollars (expressed as the number of U.S. Dollars per 1 Australian
Dollar) equal to the WM/Reuters Closing Spot Rate (Mid) as calculated at approximately 4:00 p.m. London time and published at approximately 4:15 p.m. London time as referenced by Bloomberg page WMCO1 “AUD” below “MID,” or any
successor or replacement service or page, on such Currency Trading Day. 

  

	 	•	 	 Norwegian Krone – the rate for conversion of Norwegian Kroner into U.S. Dollars (expressed as the number of U.S. Dollars per 1 Norwegian Krone)
equal to one divided by the WM/Reuters Closing Spot Rate (Mid) as calculated at approximately 4:00 p.m. London time and published at approximately 4:15 p.m. London time as referenced by Bloomberg page WMCO1 “NOK” below “MID,” or
any successor or replacement service or page, rounded to five decimal places, with .000005 rounded upwards to .00001, on such Currency Trading Day. 

  

	 	•	 	 Canadian Dollar – the rate for conversion of Canadian Dollars into U.S. Dollars (expressed as the number of U.S. Dollars per 1 Canadian Dollar)
equal to one divided by the WM/Reuters Closing Spot Rate (Mid) as calculated at approximately 4:00 p.m. London time and published at approximately 4:15 p.m. London time as referenced by Bloomberg page WMCO1 “CAD” below “MID,” or
any successor or replacement service or page, rounded to five decimal places, with .000005 rounded upwards to .00001, on such Currency Trading Day.

to close in New York, New York or Minneapolis, Minnesota. 
 The “Calculation Days” shall be, for each Basket
Component, on the last Currency Trading Day of each February and August for that Basket Component, commencing August 2012 and ending August 2016. If the Exchange Rate for a Basket Component is not published on a Calculation Day, such Calculation Day
for such Basket Component will be postponed to the first succeeding Currency Trading Day on which the Exchange Rate for such Basket Component is published. If such first succeeding Currency Trading Day has not occurred as of the fifth scheduled
Currency Trading Day after a scheduled Calculation Day for such Basket Component, that fifth scheduled Currency Trading Day shall be deemed a Calculation Day. If a Calculation Day has been postponed five scheduled Currency Trading Days after a
scheduled Calculation 

  
 3 

 
Day for such Basket Component and such fifth scheduled Currency Trading Day is not a Currency Trading Day, or if the Exchange Rate with respect to such Basket Component on such fifth scheduled
Currency Trading Day is not published, the Calculation Agent will determine the Exchange Rate of such Basket Component on such fifth scheduled Currency Trading Day in a commercially reasonable manner. Notwithstanding a postponement of a Calculation
Day for a particular Basket Component due to the non-publication of the Exchange Rate for such Basket Component, the originally scheduled Calculation Day will remain a Calculation Day for any Basket Component for which an Exchange Rate is published.

 A “Currency Trading Day,” with respect to a Basket Component, means a day on which commercial banks are open
for business (including dealings in foreign exchange in accordance with the market practice of the foreign exchange market) in New York, New York and in the principal financial center for the applicable Basket Component (Sydney, Australia, with
respect to the Australian Dollar; Oslo, Norway, with respect to the Norwegian Krone; and Toronto, Canada, with respect to the Canadian Dollar) and are not otherwise required by law, regulation or executive order to close. 

“Calculation Agent Agreement” shall mean the Calculation Agent Agreement dated as of March 7, 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 Average 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. 

Adjustments to a Basket Component 
 If, after the Pricing Date and on or before a Calculation Day, any country issuing a Basket Component (the “issuing entity”) has lawfully eliminated, converted, redenominated or exchanged
its lawful currency that was in effect on the Pricing Date (an “original currency”) for a successor currency, then for the purpose of calculating the Average Component Return for such Basket Component, the Basket will include the
successor currency and no longer include the original currency. The Initial Component Level for the successor currency, and the Exchange Rate of the successor currency on any prior Calculation Days used in the calculation of the Average Component
Level of such successor currency, will be adjusted to reflect such successor currency in accordance with the exchange ratio set by the issuing entity for converting the original currency into the successor currency on the date that the elimination,
conversion, redenomination or exchange occurred. If there is more than one such date prior to a Calculation Day, the date closest to such Calculation Day will be selected. 

  
 4 

 Calculation Agent 
 The Calculation Agent will determine the Redemption Amount and the Average Ending Level. In addition, the Calculation Agent will (i) determine whether the Exchange Rate for a Basket Component is not
published, and, if so, determine such Exchange Rate in a commercially reasonable manner, (ii) select a successor or replacement service or page if needed, and (iii) determine if adjustments are required to the Exchange Rate of a Basket
Component as described in this Security. 
 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. 

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 8, 2016. 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; provided, however, that the Redemption Amount will be calculated using (A) the Exchange Rates ascertained on the Calculation Day(s) that occurred before the date of acceleration and (B) the Exchange Rates ascertained on the date of
acceleration and on each of the Currency Trading Days leading up to the date of acceleration in such aggregate number (including the date of acceleration) equal to the number of Calculation Days scheduled to occur after the date of acceleration.

  
  

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. 

  
 5 

 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.

(“NYMEX”) RBOB gasoline, expressed in U.S. dollars per gallon, traded on the NYMEX on that day (the “NYMEX RBOB gasoline price”) as made public by the NYMEX. 

The term “first nearby month futures contract” for a commodity on any day refers to the futures contract for that
commodity with the last Trading Day closest to such day and the term “second nearby month futures contract” for a commodity refers to the futures contract for that commodity with the last Trading Day immediately after the last
Trading Day of the first nearby month futures contract for that commodity. 
 The “Participation Rate” is 300%.

 “Business Day” shall mean a 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 or Minneapolis, Minnesota. 
 A “Trading Day” means (i) with respect to silver, any day on which the LBMA is open for trading, (ii) with respect to copper and nickel, any day the LME is open for trading,
(iii) with respect to corn and soybeans, any day the CBOT is open for trading, (iv) with respect to sugar and crude oil, any day the ICE is open for trading, and (v) with respect to gasoline, any day the NYMEX is open for trading.

 The “Calculation Day” shall be August 31, 2018. 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. 

  
 4 

 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 March 7, 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 silver: (A) a material limitation or suspension of trading in the London silver fixing market; or (B) the failure of the London Silver Market
to announce or publish the London silver fixing price; 

  

	(ii)	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; 

  

	(iii)	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

	(vi)	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; 

  
 5 

	(vii)	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; and 

  

	(viii)	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. 

 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 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.

  
 6 

 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. 
 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 10, 2018. 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. 

  
 7 

 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 K

 Due Nine Months or More From Date of Issue 
 Notes Linked to a Commodity Basket 
 due September 10, 2018

 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 

  
 10 

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

  
 11 

 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 
 No reference herein to the Indenture and no provision of this Security or the Indenture shall alter or impair the obligation of 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.
