 (d) Interest. Interest payable on any 2046 Notes Interest Payment Date (as defined
below), the 2046 Notes Maturity Date, or if applicable, the Redemption Date (as determined in accordance with Section 4.2 of the Base Indenture) shall be the amount accrued from, and including, the immediately preceding 2046 Notes Interest
Payment Date in respect of which interest has been paid or duly provided for (or from and including the original issue date of September 14, 2015 if no interest has been paid or duly provided for with respect to the 2046 Notes) to but excluding
such 2046 Notes Interest Payment Date, 2046 Notes Maturity Date or, if applicable, Redemption Date, as the case may be (each, a “2046 Notes Interest Period”). The 2046 Notes will bear interest at the rate of 4.750% per year
from the original issue date thereof to the 2046 Notes Maturity Date. Interest on the 2046 Notes shall be payable semi-annually in arrears on March 1 and September 1 of each year, beginning on March 1, 2016 (each such date, a
“2046 Notes Interest Payment Date”). The amount of interest payable for any semi-annual 2046 Notes Interest Period will be computed on the basis of a 360-day year consisting of twelve 30-day months. In the event any 2046 Notes
Interest Payment Date on or before the 2046 Notes Maturity Date falls on a day that is not a Business Day, the interest payment due on that date will be postponed to the next day that is a Business Day and no interest shall accrue as a result of
such postponement. 
 In the event the 2046 Notes Maturity Date or a Redemption Date for any Note falls on a day that is not a Business Day,
then the related payments of principal, premium, if any, and 

  
 10 

 
interest may be made on the next succeeding date that is a Business Day (and no additional interest will accumulate on the amount payable for the period from and after the 2046 Notes Maturity
Date for such 2046 Note). Interest due on the 2046 Notes Maturity Date or a Redemption Date (in each case, whether or not a 2046 Notes Interest Payment Date) will be paid to the Person to whom principal of such 2046 Notes is payable. 

(e) Sinking Fund; Holder Repurchase Right. The 2046 Notes shall not be subject to any sinking fund or analogous provision or be
redeemable at the option of the Holders. 
 (f) Forms. The 2046 Notes shall be substantially in the form of Exhibit F
attached hereto, with such modifications thereto as may be approved by the authorized officer executing the same. 
 (g) Appointment of
Agent. The Trustee will initially be the Registrar and Paying Agent with respect to the 2046 Notes. 
 (h) Defeasance. Until the
applicable 2046 Notes Maturity Date, the 2046 Notes will be subject to Sections 11.2 and 11.3 of the Base Indenture. 
 (i) Further
Issues. The Company may from time to time, without the consent of the Holders of 2046 Notes, issue additional 2046 Notes. Any such additional 2046 Notes will have the same ranking, interest rate, maturity date and other terms as the 2046 Notes.
Any such additional 2046 Notes, together with the 2046 Notes herein provided for, will constitute a single series of Securities under the Indenture.

 [FORM OF REVERSE OF 2018 NOTE] 

Indenture. 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 March 30, 2011 (as heretofore supplemented, herein called the “Base Indenture”, which term shall have the meaning
assigned to it in such instrument), as supplemented by a Fifth Supplemental Indenture dated as of September 14, 2015 (herein called the “Fifth Supplemental Indenture”, and together with the Base Indenture, the
“Indenture”), between the Company and Wells Fargo Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to
the Indenture 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 designated on the face hereof, initially limited in aggregate principal amount to $1,000,000,000. The Company may at any time issue additional securities under the Indenture in
unlimited amounts having the same terms as the Securities.  
 Optional Redemption. The Securities of this series are subject
to redemption at the Company’s option, at any time and from time to time, in whole or in part, upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities to be redeemed at his address as it appears in the
records of the Registrar, on any date prior to their Stated Maturity at a Redemption Price equal to the greater of (i) 100% of the principal amount of such Securities to be redeemed, plus accrued and unpaid interest thereon to the Redemption
Date or (ii) as determined by an Independent Investment Banker (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest
accrued as of the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 12.5 basis points, plus in each case accrued and
unpaid interest thereon to the Redemption Date; provided that unless the Company defaults in payment of the Redemption Price, on or after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for
redemption. 
 For purposes of determining the optional redemption price, the following definitions are applicable: 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The semi-annual equivalent
yield to maturity of the Comparable Treasury Issue will be computed as of the third business day immediately preceding the Redemption Date.  

“Comparable Treasury Issue” means the United States Treasury security or securities selected by the Independent
Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt
securities of comparable maturity to the remaining term of the Securities.  

  
 A-5 

 “Comparable Treasury Price” means, with respect to any Redemption Date,
(1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four
Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received. 

“Independent Investment Banker” means the Reference Treasury Dealer appointed by the Company. 

“Reference Treasury Dealer” means Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC,
their successors and two other nationally recognized investment banking firms; provided, however, that, if the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury
Dealer”), the Company shall substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date,
the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue for the Securities (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent
Investment Banker by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date.  

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 Change of Control. If a
Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Securities as described above, it will be required to make an offer to repurchase all, or any part (equal to $2,000 or an integral multiple of $1,000
in excess thereof), of each Holder’s Securities pursuant to the offer described below (the “Change of Control Offer”) on the terms set forth herein. In the Change of Control Offer, the Company will be required to offer payment
in cash equal to 101% of the aggregate principal amount of Securities repurchased plus accrued and unpaid interest, if any, on the Securities repurchased, to the date of repurchase (the “Change of Control Payment”), subject to the
rights of Holders of Securities on the relevant record date to receive interest due on the relevant Interest Payment Date. 

Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control but
after the public announcement of the pending Change of Control, the Company will be required to mail a notice to Holders of Securities describing the transaction or transactions that constitute or may constitute the Change of Control Triggering
Event and offering to repurchase the Securities on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”),
pursuant to the procedures required herein and described in such notice. The Company must comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other
securities  

  
 A-6 

 
laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To
the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions herein, the Company will be required to comply with the applicable securities laws and regulations and will not be deemed to have
breached its obligations under the Change of Control provisions herein by virtue of such conflicts. 
 On the Change of Control Payment
Date, the Company will be required, to the extent lawful, to: 
 (a) accept for payment all Securities or portions of Securities properly
tendered, and not validly withdrawn, pursuant to the Change of Control Offer; 
 (b) deposit with the Paying Agent an amount equal to the
Change of Control Payment in respect of all Securities or portions of Securities properly tendered and not validly withdrawn; and 
 (c)
deliver or cause to be delivered to the Trustee the Securities properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions of Securities being purchased by the Company. 

The Paying Agent will be required to mail promptly to each Holder who properly tendered Securities the purchase price for such Securities and
the Trustee will be required to authenticate and mail (or cause to be transferred by book entry) promptly to each such Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any; provided
that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. 
 Notwithstanding the
foregoing, the Company will not be required to make a Change of Control Offer with respect to the Securities upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise
in compliance with the requirements for such an offer made by the Company and the third party purchases all such Securities properly tendered and not validly withdrawn under its offer. Further, the Company will not be required to repurchase any
Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default. 
 For purposes of the
foregoing discussion of a repurchase at the option of Holders, the following definitions are applicable: 
 “Capital
Stock” means the capital stock of every class whether now or hereafter authorized, regardless of whether such capital stock shall be limited to a fixed sum or percentage with respect to the rights of the holders thereof to participate in
dividends and in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of such corporation.  

“Change of Control” means the occurrence of any of the following: 

  
 A-7 

 (a) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by
way of merger or consolidation), in one or more series of related transactions, of all or substantially all of the Company’s assets and the assets of its Subsidiaries, taken as a whole, to any “person” (as that term is used in
Section 13(d)(3) of the Exchange Act), other than the Company or one of its Subsidiaries; 
 (b) the consummation of any transaction
(including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its Subsidiaries, becomes the
“beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of more than 50% of the Company’s then outstanding Voting Stock or other Voting Stock into which the Company’s Voting Stock is
reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; 
 (c) the Company consolidates, or
merges with or into any person, or any person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of its Voting Stock or the Voting Stock of such other person is converted into or
exchanged for cash, securities or other property, other than any such transaction where the shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of
the Voting Stock of the surviving person or any direct or indirect parent company of the surviving person immediately after giving effect to such transaction; 

(d) the first day on which a majority of the Company’s members of its board of directors are not Continuing Directors; or 

(e) the adoption of a plan relating to the Company’s liquidation or dissolution. 

Notwithstanding paragraphs (a), (b) and (c) above, a transaction will not be considered to be a Change of Control if (a) the
Company becomes a direct or indirect wholly-owned subsidiary of a holding company and (b)(x) immediately following that transaction, the direct or indirect holders of the Voting Stock of the holding company are substantially the same as the holders
of the Company’s Voting Stock immediately prior to that transaction or (y) immediately following that transaction, no person is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.

 “Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event. 

“Continuing Directors” means, as of any date of determination, any member of the Company’s board of directors who
(a) was a member of such board of directors on September 14, 2015 or (b) was nominated for election, elected or appointed to such board of directors with the approval of a majority of the Continuing Directors who were members of such
board of directors at the time of such nomination, election or appointment (either by a specific vote or by approval of a proxy statement in which such member was named as a nominee for election as a director). 

  
 A-8 

 “Investment Grade” means a rating of Baa3 or better by Moody’s (or
its equivalent under any successor rating categories of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) or the equivalent investment grade credit rating from any additional
Rating Agency or Rating Agencies selected by the Company.  
 “Moody’s” means Moody’s Investors Service,
Inc., a subsidiary of Moody’s Corporation, and its successors. 
 “Rating Agencies” means (a) each of
Moody’s and S&P; and (b) if any of Moody’s or S&P ceases to rate the Securities or fails to make a rating of the Securities publicly available for reasons outside of the Company’s control, a “nationally recognized

S&P, or both of them, as the case may be. 
 “Rating Event” means, with respect to the Securities, the rating on
the Securities is lowered below Investment Grade by each of the Rating Agencies on any date beginning on the date of public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice
of the occurrence of the Change of Control (which 60-day period shall be extended so long as the rating of the Securities is under publicly announced consideration for possible downgrade by any of the Rating Agencies). 

“S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc., and
its successors.  
 “Voting Stock” means, with respect to any specified person as of any date, the Capital

 No

Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. 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.

 [FORM OF REVERSE OF 2020 NOTE] 

Indenture. 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 March 30, 2011 (as heretofore supplemented, herein called the “Base Indenture”, which term shall have the meaning
assigned to it in such instrument), as supplemented by a Fifth Supplemental Indenture dated as of September 14, 2015 (herein called the “Fifth Supplemental Indenture”, and together with the Base Indenture, the
“Indenture”), between the Company and Wells Fargo Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to
the Indenture 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 designated on the face hereof, initially limited in aggregate principal amount to $2,000,000,000. The Company may at any time issue additional securities under the Indenture in
unlimited amounts having the same terms as the Securities.  
 Optional Redemption. The Securities of this series are subject
to redemption at the Company’s option, at any time and from time to time, in whole or in part, upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities to be redeemed at his address as it appears in the
records of the Registrar, on any date prior to their Stated Maturity at a Redemption Price equal to the greater of (i) 100% of the principal amount of such Securities to be redeemed, plus accrued and unpaid interest thereon to the Redemption
Date or (ii) as determined by an Independent Investment Banker (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest
accrued as of the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 15 basis points, plus in each case accrued and
unpaid interest thereon to the Redemption Date; provided that unless the Company defaults in payment of the Redemption Price, on or after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for
redemption. 
 For purposes of determining the optional redemption price, the following definitions are applicable: 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The semi-annual equivalent
yield to maturity of the Comparable Treasury Issue will be computed as of the third business day immediately preceding the Redemption Date.  

“Comparable Treasury Issue” means the United States Treasury security or securities selected by the Independent
Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt
securities of comparable maturity to the remaining term of the Securities.  

  
 B-5 

 “Comparable Treasury Price” means, with respect to any Redemption Date,
(1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four
Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received. 
 “Independent
Investment Banker” means the Reference Treasury Dealer appointed by the Company. 
 “Reference Treasury Dealer”
means Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC, their successors and two other nationally recognized investment banking firms; provided, however, that, if the foregoing shall cease to
be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date,
the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue for the Securities (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent
Investment Banker by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date.  

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 Change of Control. If a
Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Securities as described above, it will be required to make an offer to repurchase all, or any part (equal to $2,000 or an integral multiple of $1,000
in excess thereof), of each Holder’s Securities pursuant to the offer described below (the “Change of Control Offer”) on the terms set forth herein. In the Change of Control Offer, the Company will be required to offer payment
in cash equal to 101% of the aggregate principal amount of Securities repurchased plus accrued and unpaid interest, if any, on the Securities repurchased, to the date of repurchase (the “Change of Control Payment”), subject to the
rights of Holders of Securities on the relevant record date to receive interest due on the relevant Interest Payment Date. 

Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control but
after the public announcement of the pending Change of Control, the Company will be required to mail a notice to Holders of Securities describing the transaction or transactions that constitute or may constitute the Change of Control Triggering
Event and offering to repurchase the Securities on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”),
pursuant to the procedures required herein and described in such notice. The Company must comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other
securities  

  
 B-6 

 
laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering
Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions herein, the Company will be required to comply with the applicable securities laws and regulations and will not be deemed
to have breached its obligations under the Change of Control provisions herein by virtue of such conflicts. 
 On the Change of
Control Payment Date, the Company will be required, to the extent lawful, to: 
 (a) accept for payment all Securities or portions of
Securities properly tendered, and not validly withdrawn, pursuant to the Change of Control Offer; 
 (b) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Securities or portions of Securities properly tendered and not validly withdrawn; and 

(c) deliver or cause to be delivered to the Trustee the Securities properly accepted together with an Officers’ Certificate stating the
aggregate principal amount of Securities or portions of Securities being purchased by the Company. 
 The Paying Agent will be
required to mail promptly to each Holder who properly tendered Securities the purchase price for such Securities and the Trustee will be required to authenticate and mail (or cause to be transferred by book entry) promptly to each such Holder a new
Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any; provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.  

Notwithstanding the foregoing, the Company will not be required to make a Change of Control Offer with respect to the Securities upon the
occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and the third party purchases all such
Securities properly tendered and not validly withdrawn under its offer. Further, the Company will not be required to repurchase any Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default. 

For purposes of the foregoing discussion of a repurchase at the option of Holders, the following definitions are applicable: 

“Capital Stock” means the capital stock of every class whether now or hereafter authorized, regardless of whether such
capital stock shall be limited to a fixed sum or percentage with respect to the rights of the holders thereof to participate in dividends and in the distribution of assets upon the voluntary or involuntary liquidation, dissolution or winding up of
such corporation.  
 “Change of Control” means the occurrence of any of the following: 

  
 B-7

way of merger or consolidation), in one or more series of related transactions, of all or substantially all of the Company’s assets and the assets of its Subsidiaries, taken as a whole, to any “person” (as that term is used in
Section 13(d)(3) of the Exchange Act), other than the Company or one of its Subsidiaries; 
 (b) the consummation of any transaction
(including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its Subsidiaries, becomes the
“beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of more than 50% of the Company’s then outstanding Voting Stock or other Voting Stock into which the Company’s Voting Stock is
reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; 
 (c) the Company consolidates, or
merges with or into any person, or any person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of its Voting Stock or the Voting Stock of such other person is converted into or
exchanged for cash, securities or other property, other than any such transaction where the shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of
the Voting Stock of the surviving person or any direct or indirect parent company of the surviving person immediately after giving effect to such transaction; 

(d) the first day on which a majority of the Company’s members of its board of directors are not Continuing Directors; or 

(e) the adoption of a plan relating to the Company’s liquidation or dissolution. 

Notwithstanding paragraphs (a), (b) and (c) above, a transaction will not be considered to be a Change of Control if (a) the
Company becomes a direct or indirect wholly-owned subsidiary of a holding company and (b)(x) immediately following that transaction, the direct or indirect holders of the Voting Stock of the holding company are substantially the same as the holders
of the Company’s Voting Stock immediately prior to that transaction or (y) immediately following that transaction, no person is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.

 B-8

its equivalent under any successor rating categories of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) or the equivalent investment grade credit rating from any additional

 “Moody’s” means Moody’s Investors
Service, Inc., a subsidiary of Moody’s Corporation, and its successors.  
 “Rating Agencies” means

replacement agency for Moody’s or S&P, or both of them, as the case may be. 
 “Rating Event” means, with
respect to the Securities, the rating on the Securities is lowered below Investment Grade by each of the Rating Agencies on any date beginning on the date of public notice of an arrangement that could result in a Change of Control until the end of

Agencies).

Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. 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.

 [FORM OF REVERSE OF 2022 NOTE] 

Indenture. 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 March 30, 2011 (as heretofore supplemented, herein called the “Base Indenture”, which term shall have the meaning
assigned to it in such instrument), as supplemented by a Fifth Supplemental Indenture dated as of September 14 2015 (herein called the “Fifth Supplemental Indenture”, and together with the Base Indenture, the
“Indenture”), between the Company and Wells Fargo Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to
the Indenture 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 designated on the face hereof, initially limited in aggregate principal amount to $1,000,000,000. The Company may at any time issue additional securities under the Indenture in
unlimited amounts having the same terms as the Securities.  
 Optional Redemption. The Securities of this series are subject
to redemption at the Company’s option, at any time and from time to time, in whole or in part, upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities to be redeemed at his address as it appears in the

 In the event of redemption of this Security in part
only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.  

Notwithstanding the foregoing, the Company will not be required to make a Change of Control Offer with respect to the Securities upon the
occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and the third party purchases all such
Securities properly tendered and not validly withdrawn under its offer. Further, the Company will not be required to repurchase any Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default.

 [FORM OF REVERSE OF 2026 NOTE] 

Indenture. 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 March 30, 2011 (as heretofore supplemented, herein called the “Base Indenture”, which term shall have the meaning

the Indenture 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 designated on the face hereof, initially limited in aggregate principal amount to $2,750,000,000. The Company may at any time issue additional securities under the Indenture in
unlimited amounts having the same terms as the Securities.  
 Optional Redemption. The Securities of this series are subject
to redemption at the Company’s option, at any time and from time to time, in whole or in part, upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities to be redeemed at his address as it appears in the
records of the Registrar, on any date prior to their Stated Maturity at a Redemption Price equal to the greater of (i) 100% of the principal amount of such Securities to be redeemed, plus accrued and unpaid interest thereon to the Redemption
Date or (ii) as determined by an Independent Investment Banker (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest
accrued as of the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 25 basis points, plus in each case accrued and
unpaid interest thereon to the Redemption Date; provided that unless the Company defaults in payment of the Redemption Price, on or after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for
redemption. 
 For purposes of determining the optional redemption price, the following definitions are applicable: 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The semi-annual equivalent
yield to maturity of the Comparable Treasury Issue will be computed as of the third business day immediately preceding the Redemption Date.  

“Comparable Treasury Issue” means the United States Treasury security or securities selected by the Independent
Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt
securities of comparable maturity to the remaining term of the Securities.  

  
 D-5 

 “Comparable Treasury Price” means, with respect to any Redemption Date,

Dealer”), the Company shall substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date,
the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue for the Securities (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent
Investment Banker by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date.  

The Securities of this series are also subject to redemption at the Company’s option, at any time on or after December 1, 2025, in
whole or in part, upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities to be redeemed at his address as it appears in the records of the Registrar, at a Redemption Price equal to 100% of the principal amount
of the Securities to be redeemed, plus accrued and unpaid interest to the Redemption Date. 
 In the event of redemption of this Security in
part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 

Change of Control. If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem
the Securities as described above, it will be required to make an offer to repurchase all, or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof), of each Holder’s Securities pursuant to the offer described below (the

and unpaid interest, if any, on the Securities repurchased, to the date of repurchase (the “Change of Control Payment”), subject to the rights of Holders of Securities on the relevant record date to receive interest due on the
relevant Interest Payment Date. 
 Within 30 days following any Change of Control Triggering Event or, at the Company’s option,
prior to any Change of Control but after the public announcement of the pending Change of Control, the Company will be required to mail a notice to Holders of Securities describing the 

  
 D-6 

 
transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Securities on the date specified in the notice, which date

connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions herein, the Company will be
required to comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions herein by virtue of such conflicts.

(a) accept for payment all Securities or portions of Securities properly tendered, and not validly withdrawn, pursuant to the Change of
Control Offer;

portions of Securities properly tendered and not validly withdrawn; and 
 (c) deliver or cause to be delivered to the Trustee the
Securities properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions of Securities being purchased by the Company. 

The Paying Agent will be required to mail promptly to each Holder who properly tendered Securities the purchase price for such
Securities and the Trustee will be required to authenticate and mail (or cause to be transferred by book entry) promptly to each such Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any;
provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.  

Notwithstanding the foregoing, the Company will not be required to make a Change of Control Offer with respect to the Securities upon the
occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and the third party purchases all such
Securities properly tendered and not validly withdrawn under its offer. Further, the Company will not be required to repurchase any Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default.

corporation.

than the Company or one of its Subsidiaries; 
 (b) the consummation of any transaction (including, without limitation, any merger or
consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its Subsidiaries, becomes the “beneficial owner” (as defined in Rule
13d-3 under the Exchange Act), directly or indirectly, of more than 50% of the Company’s then outstanding Voting Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or changed,

 [FORM OF REVERSE OF 2035 NOTE] 

Indenture. 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 March 30, 2011 (as heretofore supplemented, herein called the “Base Indenture”, which term shall have the meaning
assigned to it in such instrument), as supplemented by a Fifth Supplemental Indenture dated as of September 14, 2015 (herein called the “Fifth Supplemental Indenture”, and together with the Base Indenture, the
“Indenture”), between the Company and Wells Fargo Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to
the Indenture 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 designated on the face hereof, initially limited in aggregate principal amount to $1,000,000,000. The Company may at any time issue additional securities under the Indenture in
unlimited amounts having the same terms as the Securities.  
 Optional Redemption. The Securities of this series are subject
to redemption at the Company’s option, at any time and from time to time, in whole or in part, upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities to be redeemed at his address as it appears in the
records of the Registrar, on any date prior to their Stated Maturity at a Redemption Price equal to the greater of (i) 100% of the principal amount of such Securities to be redeemed, plus accrued and unpaid interest thereon to the Redemption
Date or (ii) as determined by an Independent Investment Banker (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest
accrued as of the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 25 basis points, plus in each case accrued and
unpaid interest thereon to the Redemption Date; provided that unless the Company defaults in payment of the Redemption Price, on or after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for
redemption. 
 For purposes of determining the optional redemption price, the following definitions are applicable: 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The semi-annual equivalent
yield to maturity of the Comparable Treasury Issue will be computed as of the third business day immediately preceding the Redemption Date.  

“Comparable Treasury Issue” means the United States Treasury security or securities selected by the Independent
Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt
securities of comparable maturity to the remaining term of the Securities.  

  
 E-5 

 “Comparable Treasury Price” means, with respect to any Redemption Date,
(1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four
Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received. 
 “Independent
Investment Banker” means the Reference Treasury Dealer appointed by the Company. 
 “Reference Treasury Dealer”
means Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC, their successors and two other nationally recognized investment banking firms; provided, however, that, if the foregoing shall cease to
be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date,
the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue for the Securities (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent
Investment Banker by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date.  

The Securities of this series are also subject to redemption at the Company’s option, at any time on or after March 1, 2035, in
whole or in part, upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities to be redeemed at his address as it appears in the records of the Registrar, at a Redemption Price equal to 100% of the principal amount
of the Securities to be redeemed, plus accrued and unpaid interest to the Redemption Date. 
 In the event of redemption of this Security in
part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 

Change of Control. If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem
the Securities as described above, it will be required to make an offer to repurchase all, or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof), of each Holder’s Securities pursuant to the offer described below (the
“Change of Control Offer”) on the terms set forth herein. In the Change of Control Offer, the Company will be required to offer payment in cash equal to 101% of the aggregate principal amount of Securities repurchased plus accrued
and unpaid interest, if any, on the Securities repurchased, to the date of repurchase (the “Change of Control Payment”), subject to the rights of Holders of Securities on the relevant record date to receive interest due on the
relevant Interest Payment Date. 
 Within 30 days following any Change of Control Triggering Event or, at the Company’s option,
prior to any Change of Control but after the public announcement of the pending Change of Control, the Company will be required to mail a notice to Holders of Securities describing the 

  
 E-6 

 
transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Securities on the date specified in the notice, which date
will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required herein and described in such notice. The Company must comply
with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in
connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions herein, the Company will be
required to comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions herein by virtue of such conflicts.  

On the Change of Control Payment Date, the Company will be required, to the extent lawful, to: 

(a) accept for payment all Securities or portions of Securities properly tendered, and not validly withdrawn, pursuant to the Change of
Control Offer; 
 (b) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or
portions of Securities properly tendered and not validly withdrawn; and 
 (c) deliver or cause to be delivered to the Trustee the
Securities properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions of Securities being purchased by the Company. 

The Paying Agent will be required to mail promptly to each Holder who properly tendered Securities the purchase price for such
Securities and the Trustee will be required to authenticate and mail (or cause to be transferred by book entry) promptly to each such Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any;
provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.  

Notwithstanding the foregoing, the Company will not be required to make a Change of Control Offer with respect to the Securities upon the
occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and the third party purchases all such
Securities properly tendered and not validly withdrawn under its offer. Further, the Company will not be required to repurchase any Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default.

13d-3 under the Exchange Act), directly or indirectly, of more than 50% of the Company’s then outstanding Voting Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or changed,
measured by voting power rather than number of shares;

consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of its Voting Stock or the Voting Stock of such other person is converted into or exchanged for cash, securities or other property,
other than any such transaction where the shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person or any
direct or indirect parent company of the surviving person immediately after giving effect to such transaction; 
 (d) the first day on which
a majority of the Company’s members of its board of directors are not Continuing Directors; or 
 (e) the adoption of a plan relating

 [FORM OF REVERSE of 2046 NOTE] 

Indenture. 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 March 30, 2011 (as heretofore supplemented, herein called the “Base Indenture”, which term shall have the meaning
assigned to it in such instrument), as supplemented by a Fifth Supplemental Indenture dated as of September 14, 2015 (herein called the “Fifth Supplemental Indenture”, and together with the Base Indenture, the
“Indenture”), between the Company and Wells Fargo Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to
the Indenture 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 designated on the face hereof, initially limited in aggregate principal amount to $2,250,000,000. The Company may at any time issue additional securities under the Indenture in
unlimited amounts having the same terms as the Securities.  
 Optional Redemption. The Securities of this series are subject
to redemption at the Company’s option, at any time and from time to time, in whole or in part, upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities to be redeemed at his address as it appears in the
records of the Registrar, on any date prior to their Stated Maturity at a Redemption Price equal to the greater of (i) 100% of the principal amount of such Securities to be redeemed, plus accrued and unpaid interest thereon to the Redemption
Date or (ii) as determined by an Independent Investment Banker (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest
accrued as of the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 30 basis points, plus in each case accrued and
unpaid interest thereon to the Redemption Date; provided that unless the Company defaults in payment of the Redemption Price, on or after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for
redemption. 
 For purposes of determining the optional redemption price, the following definitions are applicable: 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent
yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The semi-annual equivalent
yield to maturity of the Comparable Treasury Issue will be computed as of the third business day immediately preceding the Redemption Date.  

“Comparable Treasury Issue” means the United States Treasury security or securities selected by the Independent
Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt
securities of comparable maturity to the remaining term of the Securities.  

  
 F-5 

 “Comparable Treasury Price” means, with respect to any Redemption Date,
(1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four
Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received. 
 “Independent
Investment Banker” means the Reference Treasury Dealer appointed by the Company. 
 “Reference Treasury Dealer”
means Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC, their successors and two other nationally recognized investment banking firms; provided, however, that, if the foregoing shall cease to
be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company shall substitute therefor another nationally recognized investment banking firm that is a Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date,
the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue for the Securities (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent
Investment Banker by such Reference Treasury Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date.  

The Securities of this series are also subject to redemption at the Company’s option, at any time on or after September 1, 2045, in
whole or in part, upon not less than 30 nor more than 60 days’ notice mailed to each Holder of Securities to be redeemed at his address as it appears in the records of the Registrar, at a Redemption Price equal to 100% of the principal amount
of the Securities to be redeemed, plus accrued and unpaid interest to the Redemption Date. 
 In the event of redemption of this Security in
part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 

Change of Control. If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem
the Securities as described above, it will be required to make an offer to repurchase all, or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof), of each Holder’s Securities pursuant to the offer described below (the
“Change of Control Offer”) on the terms set forth herein. In the Change of Control Offer, the Company will be required to offer payment in cash equal to 101% of the aggregate principal amount of Securities repurchased plus accrued
and unpaid interest, if any, on the Securities repurchased, to the date of repurchase (the “Change of Control Payment”), subject to the rights of Holders of Securities on the relevant record date to receive interest due on the
relevant Interest Payment Date. 
 Within 30 days following any Change of Control Triggering Event or, at the Company’s option,
prior to any Change of Control but after the public announcement of the pending Change of Control, the Company will be required to mail a notice to Holders of Securities describing the 

  
 F-6 

 
transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Securities on the date specified in the notice, which date will
be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required herein and described in such notice. The Company must comply with
the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in
connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions herein, the Company will be
required to comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions herein by virtue of such conflicts. 

On the Change of Control Payment Date, the Company will be required, to the extent lawful, to: 

(a) accept for payment all Securities or portions of Securities properly tendered, and not validly withdrawn, pursuant to the Change of
Control Offer; 
 (b) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or
portions of Securities properly tendered and not validly withdrawn; and 
 (c) deliver or cause to be delivered to the Trustee the
Securities properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions of Securities being purchased by the Company. 

The Paying Agent will be required to mail promptly to each Holder who properly tendered Securities the purchase price for such Securities and
the Trustee will be required to authenticate and mail (or cause to be transferred by book entry) promptly to each such Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any; provided that
each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. 
 Notwithstanding the
foregoing, the Company will not be required to make a Change of Control Offer with respect to the Securities upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise
in compliance with the requirements for such an offer made by the Company and the third party purchases all such Securities properly tendered and not validly withdrawn under its offer. Further, the Company will not be required to repurchase any
Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default. 
 For purposes of the
foregoing discussion of a repurchase at the option of Holders, the following definitions are applicable: 
 “Capital Stock”
means the capital stock of every class whether now or hereafter authorized, regardless of whether such capital stock shall be limited to a fixed sum or percentage 

  
 F-7

corporation. 
 “Change of Control” means the occurrence of any of the following:

more series of related transactions, of all or substantially all of the Company’s assets and the assets of its Subsidiaries, taken as a whole, to any “person” (as that term is used in Section 13(d)(3) of the Exchange Act), other
than the Company or one of its Subsidiaries; 
 (b) the consummation of any transaction (including, without limitation, any merger or
consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) other than the Company or one of its Subsidiaries, becomes the “beneficial owner” (as defined in Rule
13d-3 under the Exchange Act), directly or indirectly, of more than 50% of the Company’s then outstanding Voting Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or changed,
measured by voting power rather than number of shares; 
 (c) the Company consolidates, or merges with or into any person, or any person
consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of its Voting Stock or the Voting Stock of such other person is converted into or exchanged for cash, securities or other property,
other than any such transaction where the shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person or any
direct or indirect parent company of the surviving person immediately after giving effect to such transaction; 
 (d) the first day on which
a majority of the Company’s members of its board of directors are not Continuing Directors; or 
 (e) the adoption of a plan relating
to the Company’s liquidation or dissolution. 
 Notwithstanding paragraphs (a), (b) and (c) above, a transaction will not be
considered to be a Change of Control if (a) the Company becomes a direct or indirect wholly-owned subsidiary of a holding company and (b)(x) immediately following that transaction, the direct or indirect holders of the Voting Stock of the
holding company are substantially the same as the holders of the Company’s Voting Stock immediately prior to that transaction or (y) immediately following that transaction, no person is the beneficial owner, directly or indirectly, of more
than 50% of the Voting Stock of such holding company. 
 “Change of Control Triggering Event” means the occurrence of both
a Change of Control and a Rating Event. 
 “Continuing Directors” means, as of any date of determination, any member of the
Company’s board of directors who (a) was a member of such board of directors on September 

  
 F-8 

 
14, 2015 or (b) was nominated for election, elected or appointed to such board of directors with the approval of a majority of the Continuing Directors who were members of such board of
directors at the time of such nomination, election or appointment (either by a specific vote or by approval of a proxy statement in which such member was named as a nominee for election as a director). 

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating
categories of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P) or the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected
by the Company.  
 “Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s
Corporation, and its successors. 
 “Rating Agencies” means (a) each of Moody’s and S&P; and (b) if any
of Moody’s or S&P ceases to rate the Securities or fails to make a rating of the Securities publicly available for reasons outside of the Company’s control, a “nationally recognized statistical rating organization” within the
meaning of Section 3(a)(62) of the Exchange Act that is selected by the Company (as certified by a resolution of the Company’s board of directors) as a replacement agency for Moody’s or S&P, or both of them, as the case may be.

 “Rating Event” means, with respect to the Securities, the rating on the Securities is lowered below Investment Grade by
each of the Rating Agencies on any date beginning on the date of public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of the Change of Control (which
60-day period shall be extended so long as the rating of the Securities is under publicly announced consideration for possible downgrade by any of the Rating Agencies). 

“S&P” means Standard & Poor’s Ratings Services, a division of The McGraw-Hill Companies, Inc., and its

 “Voting Stock” means, with respect to any specified person as of any date, the Capital Stock of such person

 The Indenture contains
provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture,
which provisions apply to this Security. This Security is not subject to repayment at the Holder’s option. 
 No reference herein to
the Indenture and no provision of this Security or the Indenture shall affect or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Security at the respective due
dates, place and rate, and in the Currency herein prescribed. 

  
 F-9 

 Default and Remedies. If an Event of Default with respect to Securities of this series

Amendment, Modification and Waiver. 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 each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time
outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. 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. 
 Denominations; Transfer and Exchange. As provided in the
Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the records of the Registrar, upon surrender of this Security for registration of transfer at the office or agency of the Company in any

the Holder’s attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or
transferees.  
 The Securities of this series are issuable only in registered form in denominations of $2,000 and any integral
multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor
of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made to a Holder for
any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

Persons Deemed Owners. Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent
of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by

FOR
VALUE RECEIVED, ProGreen Properties, Inc., a Delaware corporation (the “Issuer” of this Security) with at least 136,848,183
common shares issued and outstanding, issues this Security and promises to pay to JMJ Financial, a Nevada sole proprietorship,
or its Assignees (the “Investor”) the Principal Sum along with the Interest Rate and any other fees according to the
terms herein. This Note will become effective only upon execution by both parties and delivery of the first payment of Consideration
by the Investor (the “Effective Date”).

 

The
Principal Sum is up to $250,000 (two hundred fifty thousand) plus accrued and unpaid interest and any other fees. The Consideration
is $225,000 (twenty five thousand) payable by wire (there exists a $25,000 original issue discount (the “OID”)). The
Investor shall pay $30,000 of Consideration upon closing of this Note. The Investor may pay additional Consideration to the Issuer
in such amounts and at such dates as the Investor may choose, however, the Issuer has the right to reject any of those payments
within 24 hours of receipt of rejected payments. The Principal Sum due to THE Investor
shall be based on the Consideration actually paid by Investor (plus an approximate 10% original issue discount that is based on
the Consideration actually paid by the Investor as well as any other interest or fees) such
that the Issuer is only required to repay the amount funded and the Issuer is not required to repay any unfunded portion of this
Note. The Maturity Date is two years from the Effective Date of each payment (the “Maturity Date”) and
is the date upon which the Principal Sum of this Note, as well as any unpaid interest and other fees, shall be due and payable.
The Conversion Price is 60% of the average of two lowest trade prices in the 20 trading days previous to the conversion (In the
case that conversion shares are not deliverable by DWAC an additional 10% discount will apply; and if the shares are ineligible
for deposit into the DTC system and only eligible for Xclearing deposit an additional 5% discount shall apply; in the case of
both an additional cumulative 15% discount shall apply). Unless otherwise agreed in writing by both parties, at no time will the
Investor convert any amount of the Note into common stock that would result in the Investor owning more than 4.99% of the common
stock outstanding.

 

1.ZERO
Percent Interest for the First Three Months. The Issuer may repay this Note at any time on or before 90 days from
the Effective Date, after which the Issuer may not make further payments on this Note prior to the Maturity Date without written
approval from the Investor. If the Issuer repays a payment of Consideration on or before 90 days from the Effective Date of
that payment, the Interest Rate on that payment of Consideration shall be ZERO PERCENT (0%).  If the Issuer does not repay
a payment of Consideration on or before 90 days from its Effective Date, a one-time Interest charge of 12% shall be applied to
the Principal Sum. Any interest payable is in addition to the OID, and that OID remains payable regardless of time and manner
of payment by the Issuer.

 

2.Conversion.
The Investor has the right, at any time after the Effective Date, at its election, to convert all or part of the outstanding and
unpaid Principal Sum and accrued interest (and any other fees) into shares of fully paid and non-assessable shares of common stock
of the Issuer as per this conversion formula: Number of shares receivable upon conversion equals the dollar conversion amount
divided by the Conversion Price. Conversions may be delivered to the Issuer by method of the Investor’s choice (including
but not limited to email, facsimile, mail, overnight courier, or personal delivery), and all conversions shall be cashless and
not require further payment from the Investor. If no objection is delivered from the Issuer to the Investor regarding any variable
or calculation of the conversion notice within 24 hours of delivery of the conversion notice, the Issuer shall have been thereafter
deemed to have irrevocably confirmed and irrevocably ratified such notice of conversion and waived any objection thereto. The
Issuer shall deliver the shares from any conversion to the Investor (in any name directed by the Investor) within 3 (three) business
days of conversion notice delivery.

 

3.Conversion
Delays. If the Issuer fails to deliver shares in accordance with the timeframe stated in Section 2, the Investor, at any time
prior to selling all of those shares, may rescind any portion, in whole or in part, of that particular conversion attributable
to the unsold shares and have the rescinded conversion amount returned to the Principal Sum with the rescinded conversion shares
returned to the Issuer (under the Investor’s and the Issuer’s expectations that any returned conversion amounts will
tack back to the original date of the Note). In addition, for each conversion, in the event that shares are not delivered by the
fourth business day (inclusive of the day of conversion), a penalty of $2,000 per day will be assessed for each day after the
third business day (inclusive of the day of the conversion) until share delivery is made; and such penalty will be added to the
Principal Sum of the Note (under the Investor’s and the Issuer’s expectations that any penalty amounts will tack back
to the original date of the Note).

8.Remedies.
In the event of any default, the outstanding principal amount of this Note, plus accrued but unpaid interest, liquidated damages,
fees and other amounts owing in respect thereof through the date of acceleration, shall become, at the Investor’s election,
immediately due and payable in cash at the Mandatory Default Amount. The Mandatory Default Amount means the greater of (i) the
outstanding principal amount of this Note, plus all accrued and unpaid interest, liquidated damages, fees and other amounts hereon,
divided by the Conversion Price on the date the Mandatory Default Amount is either demanded or paid in full, whichever has a lower
Conversion Price, multiplied by the VWAP on the date the Mandatory Default Amount is either demanded or paid in full, whichever
has a higher VWAP, or (ii) 150% of the outstanding principal amount of this Note, plus 100% of accrued and unpaid interest, liquidated
damages, fees and other amounts hereon. Commencing five (5) days after the occurrence of any event of default that results in
the eventual acceleration of this Note, the interest rate on this Note shall accrue at an interest rate equal to the lesser of
18% per annum or the maximum rate permitted under applicable law. In connection with such acceleration described herein, the Investor
need not provide, and the Issuer hereby waives, any presentment, demand, protest or other notice of any kind, and the Investor
may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other
remedies available to it under applicable law. Such acceleration may be rescinded and annulled by the Investor at any time prior
to payment hereunder and the Investor shall have all rights as a holder of the note until such time, if any, as the Investor receives
full payment pursuant to this Section 8. No such rescission or annulment shall affect any subsequent event of default or impair
any right consequent thereon. Nothing herein shall limit the Investor’s right to pursue any other remedies available to
it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to
the Issuer’s failure to timely deliver certificates representing shares of Common Stock upon conversion of the Note as required
pursuant to the terms hereof.

 

9.No
Shorting. The Investor agrees that so long as this Note from the Issuer to the Investor remains outstanding, the Investor
will not enter into or effect “short sales” of the Common Stock or hedging transaction which establishes a net short
position with respect to the Common Stock of the Issuer. The Issuer acknowledges and agrees that upon delivery of a conversion
notice by the Investor, the Investor immediately owns the shares of Common Stock described in the conversion notice and any sale
of those shares issuable under such conversion notice would not be considered short sales.
