regular trading session. 
 The “Related Exchange” for the Underlier means each exchange or quotation

 The “Determination
Date” shall be April 1, 2016. If the originally scheduled Determination Date is not a Trading Day, the Determination Date will be postponed to the next succeeding Trading Day. The Determination Date is also subject to postponement due

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 Underlier; Alteration Of Method Of Calculation 

If the Underlier Sponsor discontinues publication of the Underlier, and the Underlier 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 Underlier (a “Successor Underlier”), then, upon the Calculation Agent’s notification of that
determination to the Trustee and the Company, the Calculation Agent will substitute the Successor Underlier as calculated by the relevant Underlier Sponsor or any other entity and calculate the Final Underlier Level as described above. Upon any
selection by the Calculation Agent of a Successor Underlier, the Company will cause notice to be given to the Holder of this Security. 

  
 3 








 In the event that the Underlier Sponsor discontinues publication of the Underlier
prior to, and the discontinuance is continuing on, the Determination Date and the Calculation Agent determines that no Successor Underlier is available at such time, the Calculation Agent will calculate a substitute Closing Level for the Underlier
in accordance with the formula for and method of calculating the Underlier last in effect prior to the discontinuance, but using only those securities that comprised the Underlier immediately prior to that discontinuance. If a Successor Underlier is
selected or the Calculation Agent calculates a level as a substitute for the Underlier, the Successor Underlier or level will be used as a substitute for the Underlier for all purposes, including the purpose of determining whether a Market
Disruption Event exists. 
 If on the Determination Date the Underlier Sponsor fails to calculate and announce the level of
the Underlier, the Calculation Agent will calculate a substitute Closing Level of the Underlier in accordance with the formula for and method of calculating the Underlier last in effect prior to the failure, but using only those securities that
comprised the Underlier immediately prior to that failure; provided that, if a Market Disruption Event occurs or is continuing on such day, then the provisions set forth below under “Market Disruption Events” shall apply in lieu of the
foregoing. 
 If at any time the Underlier Sponsor makes a material change in the formula for or the method of calculating
the Underlier, or in any other way materially modifies the Underlier (other than a modification prescribed in that formula or method to maintain the Underlier 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 Underlier is to be calculated, calculate a substitute Closing Level of the Underlier in accordance
with the formula for and method of calculating the Underlier last in effect prior to the change, but using only those securities that comprised the Underlier immediately prior to that change. Accordingly, if the method of calculating the Underlier
is modified so that the level of the Underlier 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 Underlier in order to arrive at a level of the Underlier as if it had not
been modified. 
 Market Disruption Events 

A “Market Disruption Event” means, with respect to the Underlier, 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 Underlier or any Successor Underlier 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 Underlier or any Successor Underlier on any Related Exchange at any time during the one-hour period that ends at the Close of Trading on that day, 



  
 4 









	 	
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 Underlier or any Successor Underlier 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 Underlier or any Successor Underlier 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 Underlier
or any Successor Underlier 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 Underlier or Successor Underlier or any Related Exchange fails to open for trading during its
regular trading session. 


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

  

	 	 (1)
	 the relevant percentage contribution of a security to the level of the Underlier or any Successor Underlier will be based on a comparison of
(x) the portion of the level of the Underlier attributable to that security and (y) the overall level of the Underlier or Successor Underlier, 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
Underlier or any Successor Underlier; 


  

	 	 (3)
	 the “Scheduled Closing Time” of any Relevant Exchange or Related Exchange on any Trading Day for the Underlier or any Successor
Underlier 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 



  
 5 









	 	 (4)
	 an “Exchange Business Day” means any Trading Day for the Underlier or any Successor Underlier on which each Relevant Exchange for
the securities underlying the Underlier or any Successor Underlier 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. 


 If a Market Disruption Event occurs or is continuing on the Determination Date, then the
Determination Date will be postponed to the first succeeding Trading Day on which a Market Disruption Event has not occurred and is not continuing; however, if such first succeeding Trading Day has not occurred as of the eighth Trading Day after the
originally scheduled Determination Date, that eighth Trading Day shall be deemed to be the Determination Date. If the Determination Date has been postponed eight Trading Days after the originally scheduled Determination Date and a Market Disruption
Event occurs or is continuing on such eighth Trading Day, the Calculation Agent will determine the Closing Level of the Underlier on such eighth Trading Day in accordance with the formula for and method of calculating the Closing Level of the
Underlier 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 on the Relevant Exchange) on such date of each security included in the Underlier. As used herein, “closing price” means, with respect to any security on any date, the
Relevant Exchange traded or quoted price of such security as of the Close of Trading on such date. 
 Calculation Agent 

The Calculation Agent will determine the Cash Settlement Amount and the Final Underlier Level. In addition, the Calculation
Agent will (i) determine if adjustments are required to the Closing Level of the Underlier under the circumstances described in this Security, (ii) if publication of the Underlier is discontinued, select a Successor Underlier or, if no
Successor Underlier is available, determine the Closing Level of the Underlier under the circumstances described in this Security, 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. 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 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 6, 2016. This Security is not entitled to any sinking fund. 
 Acceleration 

If an Event of Default, as defined in the Indenture, with respect to this Security shall occur and be continuing, the Cash
Settlement 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 Cash Settlement Amount hereof calculated as provided herein as though the date of acceleration was the Determination Date. 
  

 

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.

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

 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.

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 

  
 9 








 
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

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

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.

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.
