 A “Trading
Day” with respect to the Index means a day, as determined by the Calculation Agent, on which (i) the Relevant Exchanges (as defined below) with respect to the securities underlying the Index are open for trading for their regular
trading sessions and (ii) the exchanges on which futures or options contracts related to the Index or successor thereto, if applicable, are traded, are open for trading for their respective regular trading sessions. 

The “Calculation Day” shall be April 30, 2014 or, if such day is not a Trading Day, the next succeeding Trading
Day. 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 the Index on the Calculation Day, such Calculation Day will be postponed to
the first succeeding Trading Day on which a Market Disruption Event has not occurred and is not continuing. If such first succeeding Trading Day has not occurred as of the eighth scheduled Trading Day after the scheduled Calculation Day, that eighth
scheduled Trading Day shall be deemed the Calculation Day. If the Calculation Day has been postponed eight scheduled Trading Days after the scheduled Calculation Day and such eighth scheduled Trading Day is not a Trading Day, or if a Market
Disruption Event occurs or is continuing with respect to the Index on such eighth scheduled Trading Day, the Calculation Agent will determine the Closing Level of the Index on such eighth scheduled Trading Day in accordance with the formula for and
method of calculating the Closing Level of the Index last in effect prior to commencement of the Market Disruption Event, using the closing price (or, with respect to any of the relevant securities, if such date is not a Trading Day or a Market
Disruption Event has occurred, its good faith estimate of the closing price that would have prevailed for such securities) on such date of each security most recently included in the Index. See “—Market Disruption Events.” As used
herein, “closing price” means, with respect to any security on any date, the last reported sales price regular way on such date or, in case no such reported sale takes place on such date, the average of the reported closing bid and
asked prices regular way on such date, in either case on the primary organized exchange or trading system on which such security is then listed or admitted to trading. 
 “Calculation Agent Agreement” shall mean the Calculation Agent Agreement dated as of November 5, 2010 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. 
 Discontinuance Of The Index; Alteration Of Method Of
Calculation 
 If the Index Sponsor discontinues publication of the Index, and the Index Sponsor or another entity
publishes a successor or substitute equity index that the Calculation Agent 

  
 3 








 
determines, in its sole discretion, to be comparable to the Index (a “Successor Equity Index”), then, upon the Calculation Agent’s notification of that determination to the
Trustee and the Company, the Calculation Agent will substitute the Successor Equity Index as calculated by the relevant Index Sponsor or any other entity and calculate the Ending Level as described above. Upon any selection by the Calculation Agent
of a Successor Equity Index, the Company will cause notice to be given to the Holder of this Security. 
 In the event that the
Index Sponsor discontinues publication of the Index and the Calculation Agent does not select a Successor Equity Index, the Calculation Agent will compute a substitute level for the Index in accordance with the procedures last used to calculate the
Index before any discontinuance. If a Successor Equity Index is selected or the Calculation Agent calculates a level as a substitute for the Index, the Successor Equity Index or level will be used as a substitute for the Index for all purposes,
including the purpose of determining whether a Market Disruption Event exists. 
 If at any time the Index Sponsor makes a
material change in the formula for or the method of calculating the Index, or in any other way materially modifies the Index so that the Index does not, in the opinion of the Calculation Agent, fairly represent the level of the Index had those
changes or modifications not been made, then, from and after that time, the Calculation Agent will, at the close of business in New York, New York, on the date that the Closing Level of the Index is to be calculated, make any adjustments as, in the
good faith judgment of the Calculation Agent, may be necessary in order to arrive at a value of an equity index comparable to the Index as if those changes or modifications had not been made, and calculate the level of the Index with reference to
such equity index, as so adjusted. Accordingly, if the method of calculating the Index is modified so that the level of the Index is a fraction or a multiple of what it would have been if it had not been modified, then the Calculation Agent will
adjust the Index in order to arrive at a level of the Index as if it had not been modified. 
 Market Disruption Events

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

	 	(A)	A material suspension or material limitation of trading in the securities which then comprise 20% or more of the level of the Index or any Successor Equity Index has
been imposed by the Relevant Exchanges on which those securities are traded, at any time during the one-hour period preceding the Close of Trading on such day, whether by reason of movements in price exceeding limits permitted by those Relevant
Exchanges or otherwise. 

  

	 	(B)	A material suspension or material limitation of trading has occurred on that day, in each case during the one-hour period preceding the Close of Trading in options or
futures contracts related to the Index or any Successor Equity Index, on the primary exchange or quotation system on which those options or futures contracts are traded, whether by reason of movements in price exceeding levels permitted by the
exchange, the quotation system or otherwise. 


  
 4 








  

	 	(C)	Any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market
values for, the securities that then comprise 20% or more of the level of the Index or any Successor Equity Index, at any time during the one-hour period that ends at the Close of Trading on that day. 


 

	 	(D)	Any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market
values for, the futures or options contracts relating to the Index or any Successor Equity Index on the primary exchange or quotation system on which those futures or options contracts are traded, at any time during the one-hour period that ends at
the Close of Trading on that day. 

  

	 	(E)	The closure of the Relevant Exchanges on which the securities that then comprise 20% or more of the level of the Index or any Successor Equity Index are traded or the
primary exchange or quotation system on which futures or options contracts relating to the Index or any Successor Equity Index are traded prior to its scheduled Close of Trading unless the earlier closing time is announced by the Relevant Exchanges,
the primary exchange or the quotation system, as applicable, at least one hour prior to the earlier of (1) the actual closing time for the regular trading session on the Relevant Exchanges, the primary exchange or the quotation system, as
applicable, and (2) the submission deadline for orders to be entered into the relevant exchanges, the primary exchange or the quotation system, as applicable, for execution at the Close of Trading on that day. 


For purposes of determining whether a Market Disruption Event has occurred: 

 

	 	(1)	the relevant percentage contribution of a security to the level of the Index or any Successor Equity Index will be based on a comparison of (x) the portion of the
level of the Index attributable to that security and (y) the overall level of the Index or Successor Equity Index, in each case immediately before the occurrence of the Market Disruption Event; 


 

	 	(2)	“Close of Trading” means in respect of any Relevant Exchange, primary exchange or quotation system, the scheduled weekday closing time on a day on
which such Relevant Exchange, primary exchange or quotation system is scheduled to be open for trading for its respective regular trading session, without regard to after hours or any other trading outside the regular trading session hours; and


  

	 	(3)	“Relevant Exchange” for any security (or any combination thereof then underlying the Index or any Successor Equity Index) means the primary exchange or
quotation system on which such security is traded, as determined by the Calculation Agent.

 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 Closing Level of the Index under the circumstances described in this Security, (ii) if publication of the Index is discontinued, select a Successor Equity Index or, if no Successor
Equity Index is available, determine the Closing Level of the Index under the circumstances described in this Security, 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
Index. 
 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 May 7, 2014. 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 the S&P 500 Index 
 due May 7, 2014 
 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.

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.

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

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.

the Indenture shall have the meanings assigned to them in the Indenture unless otherwise defined in this Security.
