	 	(i)	 the Face Amount plus: 

  

																			
		 	 	 	Face Amount  x    	 	 	 	 Ending Level – Starting Level
	 	 	 	  x  Participation Rate	 	 	 	; and

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

The “Relevant Exchange” for any security then underlying the Index means the primary exchange or quotation
system on which such security is traded, as determined by the Calculation Agent. 
 The “Calculation Day”
shall be August 29, 2017 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

has not occurred as of the eighth Trading Day after the originally scheduled Calculation Day, that eighth Trading Day shall be deemed the Calculation Day. If the Calculation Day has been postponed eight Trading Days after the originally scheduled
Calculation Day and a Market Disruption Event occurs or is continuing with respect to the Index on such eighth Trading Day, the Calculation Agent will determine the Closing Level of the Index on such eighth 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 a Market Disruption Event has occurred,
its good faith estimate of the value of such securities at the Scheduled Closing Time (as defined below) on the Relevant Exchanges) on such date of each security included in the Index. See “—Market Disruption Events.” As used herein,

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. 

  
 3 

 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 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 prior to, and the discontinuance is continuing on, the 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 the Index in accordance with the formula for and method of calculating the Index last in effect prior to the discontinuance, but using only those securities that comprised the Index immediately prior to that
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 on the Calculation Day the Index Sponsor of the Index fails
to calculate and announce the level of the Index, the Calculation Agent will calculate a substitute Closing Level of the Index in accordance with the formula for and method of calculating the Index last in effect prior to the failure, but using only
those securities that comprised the Index immediately prior to that failure; provided that, if a Market Disruption Event occurs or is continuing on such day, then the provisions set forth above under the definition of “Calculation
Day” shall apply in lieu of the foregoing. 
 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 (other than a modification prescribed in that formula or method to maintain the Index in the event of changes in constituent stock and capitalization and
other routine events), then, from and after that time, the Calculation Agent will, at the close of business in New York, New York, on each date that the Closing Level of the Index is to be calculated, calculate a substitute Closing Level of the
Index in accordance with the formula for and method of calculating the Index last in effect prior to the change, but using only those securities that comprised the Index immediately prior to that change. 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. 

  
 4 

 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)	 The occurrence or existence of a material suspension of or limitation imposed on trading by the Relevant Exchanges or otherwise relating to
securities which 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, whether by reason of movements in price exceeding limits
permitted by those Relevant Exchanges or otherwise. 

  

	 	(B)	 The occurrence or existence of a material suspension of or limitation imposed on trading by any Related Exchange or otherwise in futures or options
contracts relating to the Index or any Successor Equity Index on any Related 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 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 the Index or any Successor Equity Index on their Relevant 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 the Index or any Successor Equity Index on any Related 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 Exchanges on which securities that then comprise 20% or more of the level of the Index or
any Successor Equity Index are traded or any Related Exchange prior to its Scheduled Closing Time unless the earlier closing time is announced by the Relevant Exchange or Related 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 Exchange or Related Exchange, as applicable, and (2) the submission deadline for orders to be entered into the Relevant Exchange or Related Exchange, as
applicable, system for execution at the Close of Trading on that day. 

  

	 	(F)	 The Relevant Exchange for any security underlying the Index or Successor Equity Index or any Related Exchange fails to open for trading during its
regular trading session. 

  
 5 

 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)	 the “Close of Trading” means the Scheduled Closing Time of the Relevant Exchanges with respect to the securities underlying the
Index or any Successor Equity Index; 

  

	 	(3)	 the “Scheduled Closing Time” of any Relevant Exchange or Related Exchange on any Trading Day for the Index or any Successor Equity
Index means the scheduled weekday closing time of such Relevant Exchange or Related 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 the Index or any Successor Equity Index on which each Relevant Exchange for
the securities underlying the Index or any Successor Equity Index and each Related Exchange are open for trading during their respective regular trading sessions, notwithstanding any such Relevant Exchange or Related Exchange closing prior to its
Scheduled Closing Time. 

 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, 

  
 6 

 
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 September 1, 2017. This Security is not entitled to any sinking fund. 
 Acceleration 

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

 

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions
shall for all purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication
hereon has been executed by the Trustee referred to on the reverse hereof by manual signature or its duly authorized agent under the Indenture referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

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

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
