MEDIUM-TERM NOTE, SERIES K 

Due Nine Months or More From Date of Issue 

Principal at Risk Securities Linked to a Global ETF Basket 

due April 5, 2019 

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), 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, on the Stated Maturity Date. The “Initial Stated Maturity
Date” shall be April 5, 2019. If the Calculation Day (as defined below) is not postponed for any Basket Component (as defined below), the Initial Stated Maturity Date will be the “Stated Maturity Date.” If the
Calculation Day is postponed for any Basket Component, the “Stated Maturity Date” shall be the later of (i) the Initial Stated Maturity Date and (ii) the third Business Day (as defined below) after the final postponed
Calculation Day. This Security shall not bear any interest. 
 Any payments 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. 

“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.” 







 Determination of Redemption Amount 

The “Redemption Amount” of this Security will equal: 

 

	 	•	 	 if the Ending Price is greater than the Starting Price: the lesser of: 



 

	 	(i)	 the Face Amount plus: 


  

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

  

	 	(ii)	 the Capped Value; 


  

	 	•	 	 if the Ending Price is less than or equal to the Starting Price, but greater than or equal to the Threshold Price: the Face Amount; or



  

	 	•	 	 if the Ending Price is less than the Threshold Price: 


  

															
		 	 	 	 Face Amount x      

 
	 	Ending Price	 	     x Multiplier

 
	 	 	  		  	
		 	 	 	 	Starting Price	 	 	 	  		  	

 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. 

“Basket” shall mean a basket comprised of the following Basket Components, with the return of each Basket
Component having the weighting noted parenthetically: iShares MSCI EAFE ETF (57%); iShares Russell 2000 ETF (16%); SPDR S&P MidCap 400 ETF Trust (15%); and iShares MSCI Emerging Markets ETF (12%).

Return of the 

  
 2 








 
SPDR S&P MidCap 400 ETF; and (D) 12% of the Component Return of the iShares MSCI Emerging Markets ETF. 

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

Final Component Price – Initial Component Price 

Initial Component Price 

  where, 
  

	 	•	 	 the “Initial Component Price” is the Fund Closing Price of such Basket Component on the Pricing Date; and 



 

	 	•	 	 the “Final Component Price” will be the Fund Closing Price of such Basket Component on the Calculation Day. 



The Initial Component Prices of the Basket Components are as follows: iShares MSCI EAFE ETF ($57.32); iShares Russell 2000 ETF
($109.20); SPDR S&P MidCap 400 ETF ($248.89); and iShares MSCI Emerging Markets ETF ($32.78). 
 The “Fund
Closing Price,” with respect to a Basket Component on any Trading Day, means the product of (i) the Closing Price of one share of such Basket Component (or one unit of any other security for which a Fund Closing Price must be
determined) on such Trading Day and (ii) the Adjustment Factor applicable to such Basket Component on such Trading Day. 

The “Closing Price” with respect to a share of a Basket Component (or one unit of any other security for which
a Closing Price must be determined) on any Trading Day means the price, at the scheduled weekday closing time, without regard to after hours or any other trading outside the regular trading session hours, of the share on the principal United States
securities exchange registered under the Securities Exchange Act of 1934, as amended, on which the share (or any such other security) is listed or admitted to trading. 

The “Adjustment Factor” means, with respect to a share of a Basket Component (or one unit of any other
security for which a Fund Closing Price must be determined), 1.0, subject to adjustment in the event of certain events affecting the shares of such Basket Component. See “Anti-dilution Adjustments Relating To A Basket Component; Alternate
Calculation—Anti-dilution Adjustments” below. 
 The “Capped Value” is 167.38% of the Face Amount
of this Security. 
 The “Threshold Price” is 85, which is equal to 85% of the Starting Price. 

The “Participation Rate” is 150%. 

The “Multiplier” is equal to the Starting Price divided by the Threshold Price. 

  
 3 








 “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. 

A “Trading Day” with respect to a Basket Component means a day, as determined by the Calculation Agent, on
which the Relevant Stock Exchange (as defined below) and each Related Futures or Options Exchange (as defined below) with respect to such Basket Component, or any successor thereto, if applicable, are scheduled to be open for trading for their
respective regular trading sessions. 
 The “Related Futures or Options Exchange” for a Basket Component
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 such Basket Component. 

The “Relevant Stock Exchange” for a Basket Component means the primary exchange or quotation system on which
shares (or other applicable securities) of such Basket Component are traded, as determined by the Calculation Agent. 
 The
“Calculation Day” shall be April 2, 2019. If such day is not a Trading Day with respect to a Basket Component, the Calculation Day for such Basket Component will be postponed to the next succeeding day that is a Trading Day
with respect to such Basket Component. Notwithstanding the postponement of the Calculation Day for a particular Basket Component due to a non-Trading Day for such Basket Component, the originally scheduled Calculation Day will remain the Calculation
Day for any Basket Component not affected by such non-Trading Day. The Calculation Day is also subject to postponement due to the occurrence of a Market Disruption Event (as defined below). If a Market Disruption Event occurs or is continuing with
respect to a Basket Component on the Calculation Day, then such 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; however, if such first succeeding Trading Day has not occurred as of the eighth Trading Day for a Basket Component after the originally scheduled Calculation Day, that eighth Trading Day shall be deemed to be
the Calculation Day. If the Calculation Day has been postponed eight Trading Days for a Basket Component after the originally scheduled Calculation Day for such Basket Component, and a Market Disruption Event occurs or is continuing with respect to
such Basket Component on such eighth Trading Day, the Calculation Agent will determine the Closing Price of such Basket Component on such eighth Trading Day based on its good faith estimate of the value of the shares (or other applicable securities)
of such Basket Component as of the Close of Trading (as defined below) on such eighth Trading Day. Notwithstanding a postponement of a Calculation Day for a particular Basket Component due to a 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 Market Disruption Event. See “—Market Disruption Events.” 

“Calculation Agent Agreement” shall mean the Calculation Agent Agreement dated as of March 18, 2015
between the Company and the Calculation Agent, as amended from time to time. 

  
 4 








 “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 Price 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, with respect to a Basket Component, 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 Exchange or otherwise relating to
the shares (or other applicable securities) of such Basket Component or any Successor Fund (as defined below) on the Relevant Stock Exchange at any time during the one-hour period that ends at the Close of Trading on such day, whether by reason of
movements in price exceeding limits permitted by such Relevant Stock Exchange 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 the shares (or other applicable securities) of such Basket Component or any Successor Fund 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, shares (or other applicable securities) of such Basket Component or any Successor Fund on the Relevant Stock Exchange 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 shares (or other applicable securities) of such Basket Component or any Successor Fund 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 of the Relevant Stock Exchange or any Related Futures or Options Exchange with respect to such Basket Component or any Successor Fund
prior to its Scheduled Closing Time unless the earlier closing time is announced by the 



  
 5 









	 	 
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 the Close of Trading on that day. 


  

	 	(F)	 The Relevant Stock Exchange or any Related Futures or Options Exchange with respect to such Basket Component or any Successor Fund fails to open
for trading during its regular trading session. 


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

	 	(1)	 “Close of Trading” means the Scheduled Closing Time of the Relevant Stock Exchange with respect to such Basket Component or any
Successor Fund; and 


  

	 	(2)	 the “Scheduled Closing Time” of the Relevant Stock Exchange or any Related Futures or Options Exchange on any Trading Day for such
Basket Component or any Successor Fund 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. 


 Anti-dilution Adjustments Relating To A Basket Component; Alternate Calculation 

Anti-dilution Adjustments 

The Calculation Agent will adjust the Adjustment Factor with respect to a Basket Component as specified below if any of the
events specified below occurs with respect to such Basket Component and the effective date or ex-dividend date, as applicable, for such event is after the Pricing Date and on or prior to the Calculation Day. 

The adjustments specified below do not cover all events that could affect a Basket Component. The Calculation Agent may, in its
sole discretion, make additional adjustments to any terms of this Security upon the occurrence of other events that affect or could potentially affect the market price of, or shareholder rights in, such Basket Component, with a view to offsetting,
to the extent practical, any such change, and preserving the relative investment risks of this Security. In addition, the Calculation Agent may, in its sole discretion, make adjustments or a series of adjustments that differ from those described
herein if the Calculation Agent determines that such adjustments do not properly reflect the economic consequences of the events specified herein or would not preserve the relative investment risks of this Security. All determinations made by the
Calculation Agent in making any adjustments to the terms of this Security, including adjustments that are in addition to, or that differ from, those described herein, will be made in good faith and a commercially reasonable manner, with the aim of
ensuring an equitable result. In determining whether to make any adjustment to the terms of this Security, the Calculation Agent may consider any adjustment made by the Options Clearing Corporation or


  
 6 








 
any other equity derivatives clearing organization on options contracts on the affected Basket Component. 

For any event described below, the Calculation Agent will not be required to adjust the Adjustment Factor unless the adjustment
would result in a change to the Adjustment Factor then in effect of at least 0.10%. The Adjustment Factor resulting from any adjustment will be rounded up or down, as appropriate, to the nearest one-hundred thousandth. 

 

	 	(A)	 Stock Splits and Reverse Stock Splits 



If a stock split or reverse stock split has occurred, then once such split has become effective, the Adjustment Factor will be
adjusted to equal the product of the prior Adjustment Factor and the number of securities which a holder of one share (or other applicable security) of the Basket Component before the effective date of such stock split or reverse stock split would
have owned or been entitled to receive immediately following the applicable effective date. 
  

	 	(B)	 Stock Dividends 



If a dividend or distribution of shares (or other applicable securities) to which this Security is linked has been made by a
Basket Component ratably to all holders of record of such shares (or other applicable security), then the Adjustment Factor will be adjusted on the ex-dividend date to equal the prior Adjustment Factor plus the product of the prior Adjustment Factor
and the number of shares (or other applicable security) of such Basket Component which a holder of one share (or other applicable security) of such Basket Component before the ex-dividend date would have owned or been entitled to receive immediately
following that date; provided, however, that no adjustment will be made for a distribution for which the number of securities of such Basket Component paid or distributed is based on a fixed cash equivalent value. 

 

	 	(C)	 Extraordinary Dividends 



If an Extraordinary Dividend (as defined below) has occurred, then the Adjustment Factor will be adjusted on the ex-dividend
date to equal the product of the prior Adjustment Factor and a fraction, the numerator of which is the Closing Price per share (or other applicable security) of such Basket Component on the Trading Day preceding the ex-dividend date, and the
denominator of which is the amount by which the Closing Price per share (or other applicable security) of such Basket Component on the Trading Day preceding the ex-dividend date exceeds the Extraordinary Dividend Amount (as defined below). 

  
 7 








 For purposes of determining whether an Extraordinary Dividend has occurred: 

 

	 	(1)	 “Extraordinary Dividend” means any cash dividend or distribution (or portion thereof) that the Calculation Agent determines, in
its sole discretion, is extraordinary or special; and 


  

	 	(2)	 “Extraordinary Dividend Amount” with respect to an Extraordinary Dividend for the securities of such Basket Component will equal
the amount per share (or other applicable security) of such Basket Component of the applicable cash dividend or distribution that is attributable to the Extraordinary Dividend, as determined by the Calculation Agent in its sole discretion.



 A distribution on the securities of such Basket Component described below under the section entitled
“—Reorganization Events” below that also constitutes an Extraordinary Dividend will only cause an adjustment pursuant to that “—Reorganization Events” section. 

 

	 	(D)	 Other Distributions 



If a Basket Component declares or makes a distribution to all holders of the shares (or other applicable security) of such
Basket Component of any non-cash assets, excluding dividends or distributions described under the section entitled “—Stock Dividends” above, then the Calculation Agent may, in its sole discretion, make such adjustment (if any) to the
Adjustment Factor as it deems appropriate in the circumstances. If the Calculation Agent determines to make an adjustment pursuant to this paragraph, it will do so with a view to offsetting, to the extent practical, any change in the economic
position of a holder of this Security that results solely from the applicable event. 
  

	 	(E)	 Reorganization Events 



If a Basket Component, or any Successor Fund, is subject to a merger, combination, consolidation or statutory exchange of
securities with another exchange traded fund, and such Basket Component to which this Security is linked is not the surviving entity (a “Reorganization Event”), then, on or after the date of such event, the Calculation Agent shall,
in its sole discretion, make an adjustment to the Adjustment Factor or the method of determining the Redemption Amount or any other terms of this Security as the Calculation Agent determines appropriate to account for the economic effect on this
Security of such event, and determine the effective date of that adjustment. If the Calculation Agent determines that no adjustment that it could make will produce a commercially reasonable result, then the Calculation Agent may deem such event a
Liquidation Event (as defined below). 

  
 8 








 Liquidation Events 

If a Basket Component is de-listed, liquidated or otherwise terminated (a “Liquidation Event”), and a
successor or substitute exchange traded fund exists that the Calculation Agent determines, in its sole discretion, to be comparable to such Basket Component, then, upon the Calculation Agent’s notification of that determination to the Trustee
and the Company, any subsequent Fund Closing Price for such Basket Component will be determined by reference to the Fund Closing Price of such successor or substitute exchange traded fund (such exchange traded fund being referred to herein as a
“Successor Fund”), with such adjustments as the Calculation Agent determines are appropriate to account for the economic effect of such substitution on the holder of this Security. 

If a Basket Component undergoes a Liquidation Event prior to, and such Liquidation Event is continuing on, the date that any
Fund Closing Price of such Basket Component is to be determined and the Calculation Agent determines that no Successor Fund is available at such time, then the Calculation Agent will, in its discretion, calculate the Fund Closing Price for such
Basket Component on such date by a computation methodology that the Calculation Agent determines will as closely as reasonably possible replicate such Basket Component, provided that if the Calculation Agent determines in its discretion that it is
not practicable to replicate such Basket Component (including but not limited to the instance in which the sponsor of the index underlying such Basket Component discontinues publication of that index), then the Calculation Agent will calculate the
Fund Closing Price for such Basket Component in accordance with the formula last used to calculate such Fund Closing Price before such Liquidation Event, but using only those securities that were held by such Basket Component immediately prior to
such Liquidation Event without any rebalancing or substitution of such securities following such Liquidation Event. 
 If a
Successor Fund is selected or the Calculation Agent calculates the Fund Closing Price as a substitute for such Basket Component, such Successor Fund or Fund Closing Price will be used as a substitute for such Basket Component for all purposes,
including for purposes of determining whether a Market Disruption Event exists. 
 If any event is both a Reorganization
Event and a Liquidation Event, such event will be treated as a Reorganization Event for purposes of this Security unless the Calculation Agent makes the determination referenced in the last sentence of the section entitled “—Anti-dilution
Adjustments—Reorganization Events” above. 
 Alternate Calculation 

If at any time the method of calculating a Basket Component or a Successor Fund, or the related Underlying Index, is changed in
a material respect, or if a Basket Component or a Successor Fund is in any other way modified so that such Basket Component does not, in the opinion of the Calculation Agent, fairly represent the price of the securities of such Basket Component or
such Successor Fund had such changes or modifications not been made, then the Calculation Agent may, at the close of business in New York City on the date that any Fund Closing 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 Closing Price of an 

  
 9 








 
exchange traded fund comparable to such Basket Component or such Successor Fund, as the case may be, as if such changes or modifications had not been made, and calculate the Fund Closing Price
and the Redemption Amount with reference to such adjusted Closing Price of such Basket Component or such Successor Fund, as applicable. 
 Calculation
Agent 
 The Calculation Agent will determine the Redemption Amount and the Ending Price. In addition, the
Calculation Agent will (i) determine if adjustments are required to the Fund Closing Price and/or the Adjustment Factor of a Basket Component under the circumstances described in this Security, (ii) if a Basket Component undergoes a
Liquidation Event, select a Successor Fund or, if no Successor Fund is available, determine the Fund Closing Price of such Basket Component, and (iii) determine whether a Market Disruption Event or non-Trading Day 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. 

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 treat this Security as a prepaid derivative contract that is an “open
transaction.” 
 Redemption and Repayment 

This Security is not subject to redemption at the option of the Company or repayment at the option of the Holder hereof prior
to April 5, 2019. 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. 

  
 10 








 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. 
 [The remainder of this page has been left intentionally blank]

 IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed
under its corporate seal.

WELLS FARGO & COMPANY 

MEDIUM-TERM NOTE, SERIES K 

Due Nine Months or More From Date of Issue 

Principal at Risk Securities Linked to a Global ETF Basket 

due April 5, 2019 

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 

  
 13 








 
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

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.

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

definitive Securities in registered 

  
 14
