 due April 3, 2023 

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, an amount equal to the
Redemption Amount (as defined below) on the Stated Maturity Date (as defined below), unless this Security is redeemed prior to the Stated Maturity Date as provided below under “Optional Redemption,” and to pay Contingent Coupon Payments
(as defined below) on the Face Amount of this Security to the extent provided herein on the Contingent Coupon Payment Dates specified herein at the Contingent Coupon Rate (as defined below) until the earlier of the Stated Maturity Date and the
Optional Redemption Date (as defined below), if any. The “Initial Stated Maturity Date” shall be April 3, 2023. If the Final Calculation Day (as defined below) is not postponed, the Initial Stated Maturity Date will be the
“Stated Maturity Date.” If the Final Calculation Day is postponed, the “Stated Maturity Date” shall be the later of (i) the Initial Stated Maturity Date and (ii) three Business Days (as defined below)
after the last Final Calculation Day as postponed. 
 “Face Amount” shall mean, when used with respect to
this Security, the amount set forth on the face of this Security as its “Face Amount.” 
 Optional Redemption 

The Company may, at its option, redeem this Security, in whole but not in part, on any Optional Redemption Date (as defined
below) by giving notice to the Holder hereof on or before the 









 
Calculation Day (as defined below) immediately preceding that Optional Redemption Date. If this Security is redeemed, the Holder hereof will receive the Optional Redemption Price (as defined
below) plus a final Contingent Coupon Payment (as defined below), if any, on the applicable Optional Redemption Date. Unless the Company defaults in the payment of the Optional Redemption Price plus the final Contingent Coupon Payment, if any, this
Security will cease to be outstanding on such Optional Redemption Date, no additional Contingent Coupon Payments will be payable on this Security and the Holder hereof will have no further rights under this Security after such Optional Redemption
Date. The “Optional Redemption Price” is equal to the Face Amount of this Security. The “Optional Redemption Dates” shall be the Contingent Coupon Payment Dates (as defined below) following each Calculation Day
scheduled to occur from March 2019 to December 2022, inclusive. 
 Payment of Contingent Coupon Payments, the Redemption Amount and the Optional
Redemption Price 
 On each quarterly Contingent Coupon Payment Date, the Company shall pay a Contingent Coupon
Payment if, and only if, the Closing Level (as defined below) of the Lowest Performing Index (as defined below) on the related Calculation Day is greater than or equal to its Coupon Threshold Level (as defined below). A “Contingent Coupon
Payment,” if payable as provided herein, shall be equal to the product of (i) the Face Amount of this Security, (ii) the Contingent Coupon Rate, and (iii) 90/360. The “Contingent Coupon Payment Dates” shall
be the third Business Day following each Calculation Day, as each such Calculation Day may be postponed as herein provided, provided that the Contingent Coupon Payment Date with respect to the Final Calculation Day will be the Stated Maturity Date.
If a Calculation Day is postponed with respect to one or more Indices, the related Contingent Coupon Payment Date will be three Business Days after the last Calculation Day as postponed. The “Contingent Coupon Rate” is 7.10% per
annum. Any Contingent Coupon Payments will be rounded to the nearest cent, with one-half cent rounded upward. 

Any Contingent Coupon Payment so payable, and punctually paid or duly provided for, on any Contingent Coupon 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 Contingent Coupon Payment next preceding such
Contingent Coupon Payment Date. The Regular Record Date for a Contingent Coupon Payment Date shall be the date one Business Day prior to such Contingent Coupon Payment Date. 

Any Contingent Coupon Payment 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 any Contingent Coupon Payment 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; provided, however, that, at the option of the Company, payment of any Contingent Coupon Payment 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. Payments of any Contingent Coupon Payment and the
Redemption Amount or the Optional Redemption Price, as applicable, 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 and at any other office or agency maintained by the Company for such purpose. Notwithstanding the foregoing, for so long as this Security is a Global Security registered in the name of the Depositary, any payments on this Security will be
made to the Depositary by wire transfer of immediately available funds. 
 Payment of the Redemption Amount or the Optional
Redemption Price, as applicable, and any Contingent Coupon Payments on this Security will be made 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.

than or equal to its Downside Threshold Level: the Face Amount; or 


  

	 	•	 	 if the Ending Level of the Lowest Performing Index on the Final Calculation Day is less than its Downside
Threshold Level:

		 		 		 		 	 	 	 	 	Index on the Final Calculation Day	 	 	 		 		 		 		 	

 All calculations with respect to the Redemption Amount will be rounded to the nearest one hundred-thousandth,
with five one-millionths rounded upward (e.g., 0.000005 would be rounded to 0.00001); and the Redemption Amount will be rounded to the nearest cent, with one-half cent
rounded upward. 
 “Index” shall mean each of the S&P 500 Index, the Russell 2000 Index and the Dow
Jones Industrial Average. 
 The “Pricing Date” shall mean March 29, 2018. 

The “Lowest Performing Index” for any Calculation Day will be the Index with the lowest Performance Factor on
that Calculation Day (as such Calculation Day may be postponed for one or more Indices). 

  
 3 










 The “Performance Factor” with respect to an Index on any
Calculation Day is its Closing Level on such Calculation Day divided by its Starting Level (expressed as a percentage). 

The “Starting Level” with respect to the S&P 500 Index is 2640.87, its Closing Level on the Pricing Date,
with respect to the Russell 2000 Index is 1529.427, its Closing Level on the Pricing Date, and with respect to the Dow Jones Industrial Average is 24103.11, its Closing Level on the Pricing Date. 

The “Ending Level” of an Index will be its Closing Level on the Final Calculation Day. 

The “Coupon Threshold Level” with respect to the S&P 500 Index is 1584.522, which is equal to 60% of its
Starting Level, with respect to the Russell 2000 Index is 917.6562, which is equal to 60% of its Starting Level, and with respect to the Dow Jones Industrial Average is 14461.866, which is equal to 60% of its Starting Level.

its Starting Level, with respect to the Russell 2000 Index is 764.7135, which is equal to 50% of its Starting Level, and with respect to the Dow Jones Industrial Average is 12051.555, which is equal to 50% of its Starting Level. 

The “Closing Level” with respect to each Index on any Trading Day means the official closing level of that
Index reported by the relevant Index Sponsor on such Trading Day, as obtained by the Calculation Agent on such Trading Day from the licensed third-party market data vendor contracted by the Calculation Agent at such time; in particular, taking into
account the decimal precision and/or rounding convention employed by such licensed third-party market data vendor on such date, subject to the provisions set forth below under “—Market Disruption Events,” “—Adjustments to an
Index” and “—Discontinuance of an Index.” 
 “Index Sponsor” shall mean the sponsor or
publisher of an Index.

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. 

The “Calculation Days” shall be the 29th day of each
March, June, September and December, commencing June 2018 and ending December 2022, and the Final Calculation Day. If any such day is not a Trading Day with respect to any Index, such Calculation Day for each Index will be postponed to the next
succeeding day that is a Trading Day with respect to each Index. A Calculation Day for an Index is also subject to postponement due to the occurrence of a Market Disruption Event (as defined below) with respect to such Index on such Calculation Day.
The “Final Calculation Day” is March 29, 2023. If a Market Disruption Event occurs or is continuing with respect to an Index on any Calculation Day, then such Calculation Day for such Index will be postponed to the first
succeeding Trading Day for such Index on which a Market Disruption Event for such Index has not occurred and is not continuing; however, if such first succeeding Trading Day has not occurred as of the eighth Trading Day for such Index after the
originally scheduled Calculation Day, that eighth Trading Day shall be deemed to be the Calculation Day for such Index. If a Calculation Day has been postponed eight Trading Days for an Index after the originally scheduled Calculation Day and a
Market Disruption Event occurs or 

  
 4 










 
is continuing with respect to such Index on such eighth Trading Day, the Calculation Agent will determine the Closing Level of such Index on such eighth Trading Day in accordance with the formula
for and method of calculating the Closing Level of such Index last in effect prior to commencement of the Market Disruption Event, using the closing price (or, with respect to any relevant security, if a Market Disruption Event has occurred with
respect to such security, its good faith estimate of the value of such security at the Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant
Stock Exchange) on that day of each security included in such Index. As used herein, “closing price” means, with respect to any security on any date, the Relevant Stock Exchange traded or quoted price of such security as of the
Scheduled Closing Time of the Relevant Stock Exchange for such security or, if earlier, the actual closing time of the regular trading session of such Relevant Stock Exchange. Notwithstanding the postponement of a Calculation Day for an Index due to
a Market Disruption Event with respect to such Index on such Calculation Day, the originally scheduled Calculation Day will remain the Calculation Day for any Index not affected by a Market Disruption Event on such day. 

“Calculation Agent Agreement” shall mean the Calculation Agent Agreement dated as of January 24, 2018
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, whether a Contingent Coupon Payment will be made, the Optional Redemption Price, if any, and the Redemption Amount, if any,
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. 

Certain Definitions 
 A
“Trading Day” with respect to an Index means a day, as determined by the Calculation Agent, on which (i) the Relevant Stock Exchanges with respect to each security underlying such Index are scheduled to be open for trading for
their respective regular trading sessions and (ii) each Related Futures or Options Exchange with respect to such Index is scheduled to be open for trading for its regular trading session. 

The “Relevant Stock Exchange” for any security underlying an Index means the primary exchange or quotation
system on which such security is traded, as determined by the Calculation Agent. 
 The “Related Futures or Options
Exchange” for an Index means an exchange or quotation system where trading has a material effect (as determined by the Calculation Agent) on the overall market for futures or options contracts relating to such Index. 

  
 5 










 Adjustments to an Index 

If at any time the method of calculating an Index or a Successor Equity Index, or the closing level thereof, is changed in a
material respect, or if an Index or a Successor Equity Index is in any other way modified so that such index does not, in the opinion of the Calculation Agent, fairly represent the level of such index had those changes or modifications not been
made, then the Calculation Agent will, at the close of business in New York, New York, on each date that the closing level of such index is to be calculated, make such calculations and adjustments as, in the good faith judgment of the Calculation
Agent, may be necessary in order to arrive at a level of an index comparable to such Index or Successor Equity Index as if those changes or modifications had not been made, and the Calculation Agent will calculate the closing level of such Index or
Successor Equity Index with reference to such index, as so adjusted. Accordingly, if the method of calculating an Index or Successor Equity Index is modified so that the level of such index is a fraction or a multiple of what it would have been if
it had not been modified (e.g., due to a split or reverse split in such equity index), then the Calculation Agent will adjust such Index or Successor Equity Index in order to arrive at a level of such index as if it had not been modified
(e.g., as if the split or reverse split had not occurred). 
 Discontinuance of an Index 

If an Index Sponsor discontinues publication of an Index, and such Index Sponsor or another entity publishes a successor or
substitute equity index that the Calculation Agent determines, in its sole discretion, to be comparable to such 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 for purposes of calculating the Closing Level of such Index on any date of determination. 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 an Index Sponsor discontinues publication of an Index prior to, and the discontinuance is continuing on, a
Calculation Day and the Calculation Agent determines that no Successor Equity Index is available at such time, the Calculation Agent will calculate a substitute Closing Level for such Index in accordance with the formula for and method of
calculating such Index last in effect prior to the discontinuance, but using only those securities that comprised such Index immediately prior to that discontinuance. If a Successor Equity Index is selected or the Calculation Agent calculates a
level as a substitute for such Index, the Successor Equity Index or level will be used as a substitute for such Index for all purposes, including the purpose of determining whether a Market Disruption Event exists. 

If on a Calculation Day an Index Sponsor fails to calculate and announce the level of an Index, the Calculation Agent will
calculate a substitute Closing Level of such Index in accordance with the formula for and method of calculating such Index last in effect prior to the failure, but using only those securities that comprised such Index immediately prior to that
failure; provided that, if a Market Disruption Event occurs or is continuing on such day with respect to such Index, then the provisions set forth above under the definition of “Calculation Days” shall apply in lieu of the
foregoing. 

  
 6 










 Market Disruption Events 

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

	 	(A)	 The occurrence or existence of a material suspension of or limitation imposed on trading by the Relevant Stock
Exchanges or otherwise relating to securities which then comprise 20% or more of the level of such Index or any Successor Equity Index at any time during the one-hour period that ends at the Close of Trading
on that day, whether by reason of movements in price exceeding limits permitted by those Relevant Stock Exchanges or otherwise. 


  

	 	(B)	 The occurrence or existence of a material suspension of or limitation imposed on trading by any Related
Futures or Options Exchange or otherwise in futures or options contracts relating to such Index or any Successor Equity Index on any Related Futures or Options Exchange at any time during the one-hour period
that ends at the Close of Trading on that day, whether by reason of movements in price exceeding limits permitted by the Related Futures or Options Exchange or otherwise. 



 

	 	(C)	 The occurrence or existence of 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, securities that then comprise 20% or more of the level of such Index or any Successor Equity Index on their Relevant Stock Exchanges at any time during
the one-hour period that ends at the Close of Trading on that day. 


  

	 	(D)	 The occurrence or existence of 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, futures or options contracts relating to such Index or any Successor Equity Index on any Related Futures or Options Exchange at any time during the one-hour period that ends at the Close of Trading on that day. 


  

	 	(E)	 The closure on any Exchange Business Day of the Relevant Stock Exchanges on which securities that then
comprise 20% or more of the level of such Index or any Successor Equity Index are traded or any Related Futures or Options Exchange with respect to such Index or any Successor Equity Index prior to its Scheduled Closing Time unless the earlier
closing time is announced by the Relevant Stock Exchange or Related Futures or Options Exchange, as applicable, at least one hour prior to the earlier of (1) the actual closing time for the regular trading session on such Relevant Stock
Exchange or Related Futures or Options Exchange, as applicable, and (2) the submission deadline for orders to be entered into the Relevant Stock Exchange or Related Futures or Options Exchange, as applicable, system for execution at such actual
closing time on that day. 



  
 7 











	 	(F)	 The Relevant Stock Exchange for any security underlying such Index or Successor Equity Index or any Related
Futures or Options Exchange with respect to such Index or Successor Equity Index fails to open for trading during its regular trading session. 



For purposes of determining whether a Market Disruption Event has occurred with respect to an Index: 

 

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


  

	 	(2)	 the “Close of Trading” on any Trading Day for such Index or any Successor Equity Index means
the Scheduled Closing Time of the Relevant Stock Exchanges with respect to the securities underlying such Index or Successor Equity Index on such Trading Day; provided that, if the actual closing time of the regular trading session of any such
Relevant Stock Exchange is earlier than its Scheduled Closing Time on such Trading Day, then (x) for purposes of clauses (A) and (C) of the definition of “Market Disruption Event” above, with respect to any security underlying
such Index or Successor Equity Index for which such Relevant Stock Exchange is its Relevant Stock Exchange, the “Close of Trading” means such actual closing time and (y) for purposes of clauses (B) and (D) of the definition of
“Market Disruption Event” above, with respect to any futures or options contract relating to such Index or Successor Equity Index, the “Close of Trading” means the latest actual closing time of the regular trading session of any
of the Relevant Stock Exchanges, but in no event later than the Scheduled Closing Time of the Relevant Stock Exchanges; 


  

	 	(3)	 the “Scheduled Closing Time” of any Relevant Stock Exchange or Related Futures or Options
Exchange on any Trading Day for such Index or any Successor Equity Index means the scheduled weekday closing time of such Relevant Stock Exchange or Related Futures or Options Exchange on such Trading Day, without regard to after hours or any other
trading outside the regular trading session hours; and 


  

	 	(4)	 an “Exchange Business Day” means any Trading Day for such Index or any Successor Equity Index
on which each Relevant Stock Exchange for the securities underlying such Index or any Successor Equity Index and each Related Futures or Options Exchange with respect to such Index or any Successor Equity Index are open for trading during their
respective regular trading sessions, notwithstanding any such Relevant Stock Exchange or Related Futures or Options Exchange closing prior to its Scheduled Closing Time. 



Calculation Agent 

The Calculation Agent will determine whether a Contingent Coupon Payment will be made, the Optional Redemption Price, if any,

Principal at Risk Securities Linked to the Lowest Performing of the S&P 500®
Index, 
 the Russell 2000® Index and the Dow Jones Industrial AverageSM 
 due April 3, 2023 

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 February 21, 2017, 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 S, of the Company. 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.

 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 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


  
 11 










 
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

Indenture, relating to defeasance at any time of (a) the entire indebtedness on this Security and (b) certain restrictive covenants, 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, bearing interest at the same rate, having the same date of issuance, Stated Maturity Date and other terms and of authorized denominations aggregating a like amount. 

  
 12 










 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,
