 The maximum aggregate principal amount of the
Notes which may be authenticated and delivered pursuant to the Indenture (except for (i) Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Section 304, 305, 306,
906 or 1107 of the Original Indenture, (ii) Notes which, pursuant to Section 303 of the Original Indenture, are deemed never to have been authenticated and delivered under the Indenture, and (iii) for avoidance of doubt, Additional

then the Company shall be required to redeem all of the outstanding Special Mandatory Redemption Notes on the Special Mandatory Redemption Date at a redemption price equal to 101% of the aggregate principal amount of such Notes, plus accrued and
unpaid interest on the principal amount of such Notes to, but not including, the Special Mandatory Redemption Date. Notwithstanding the foregoing, installments of interest on the Special Mandatory Redemption Notes that are due and payable on
Interest Payment Dates falling on or prior to the Special Mandatory Redemption Date will be payable on such Interest Payment Dates to the registered Holders of Special Mandatory Redemption Notes as of the close of business on the relevant Regular

be no later than 30 days following any 

  
 6 

 
Special Mandatory Redemption Event, but no earlier than the fifth Business Day following the day the notice of special mandatory redemption is sent to Holders of Special Mandatory Redemption
Notes. If funds sufficient to pay the redemption price for the Special Mandatory Redemption Notes on the Special Mandatory Redemption Date are deposited with the Trustee or a Paying Agent on or before such Special Mandatory Redemption Date, then, on
and after such Special Mandatory Redemption Date, such Notes will cease to bear interest. 
 (b) To the extent not otherwise set forth in
Section 209(a) of this Eighth Supplemental Indenture, the provisions of Sections 1104 through 1107 of the Original Indenture shall apply to any redemption pursuant to Section 209(a) of this Eighth Supplemental Indenture, except to the
extent that any provision of Sections 1104 through 1107 conflicts with any provision of Section 209(a) of this Eighth Supplemental Indenture, in which case the provisions of Section 209(a) of this Eighth Supplemental Indenture shall govern
and be controlling. 
  

	210.	Exchange of the Notes 

 In addition to the circumstances set forth in Clause (2) of
the last paragraph of Section 305 of the Original Indenture, and subject to the arrangements then existing between the Company and the applicable Depositary, the Company may at any time, in its sole discretion, elect to have any Global Note
exchanged in whole or in part for Notes of the same series registered in the name or names of Persons other than such Depositary or a nominee thereof.

party is or has agreed to be subject to, the Company agrees (i) upon reasonable written request of the Trustee, to use commercially reasonable efforts to provide to the Trustee, to the extent available, sufficient information about Holders or
other applicable parties and/or transactions (including any modification to the terms of such transactions) so that the Trustee can determine whether it has tax related obligations under Applicable Tax Law and (ii) that the Trustee shall be
entitled to make any withholding or deduction in respect of taxes 

  
 8 

 
from payments under the Indenture to the extent necessary to comply with Applicable Tax Law for which the Trustee shall not have any liability. Nothing in the immediately preceding sentence shall
be construed as obligating the Company to make any “gross up” payment or similar reimbursement in connection with a payment in respect of which amounts are so withheld or deducted. The terms of this paragraph shall survive the satisfaction

October 15, 2020 (the “Maturity Date”), and to pay interest thereon from October 13, 2017 (the “Original Issue Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for,
semi-annually in arrears on April 15 and October 15 in each year (each an “Interest Payment Date”), commencing April 15, 2018, at the rate of 2.080% per annum until the principal hereof is paid or made available for
payment. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date and on the Maturity Date will, as provided in the Indenture,
be paid to the Person in whose name this Note (or one or more Predecessor Securities to this Note (the “Predecessor Notes”)) is registered at the close of business on the April 1 or October 1 (whether or not a Business Day)

Person on such Regular Record Date and may either be paid to the Holder in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed
by the Trustee under the Indenture, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may
be, will be the amount of interest accrued from and including the immediately preceding Interest Payment Date (or from and including the Original Issue Date, in the case of the initial Interest Payment Date) to but excluding the applicable Interest
Payment Date or the Maturity Date, as the case may be. If an Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the payment will be made on the next Business Day as if it were made on the date the payment was due,
and no interest will accrue on the amount so payable for the period from and after that Interest Payment Date or the Maturity Date, as the case may be. 

2. Method of Payment. The Company will pay the principal of and premium, if any, and interest on the Notes in money of the United States of America that at
the time of payment is legal tender for payment of public and private debts. [The Company will make all payments of interest on this Global Note in accordance with the arrangements then existing between the Paying Agent and the Depositary, and all

 3. Paying Agent

of transfer or exchange. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to any Holders, and the Company or any Subsidiary may act as Paying Agent or Security Registrar for the Notes. 

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of
November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental Indenture dated as of
March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”) and an Eighth Supplemental Indenture dated as of October 13,
2017 (the “Eighth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture, the “Indenture”), by and between the
Company and The Bank of New York Mellon, as Trustee (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, and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

This Note is one of the series designated as the “2.080% Senior Notes due 2020” of the Company initially limited in aggregate
principal amount to $1,000,000,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”). Any such
Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date and the
initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided,
however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from
the Notes. Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of
the Company and rank pari passu with all unsecured and unsubordinated obligations of the Company. 
 The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a
statement of all those terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

 Capitalized terms used but not defined in this Note have the respective meanings ascribed to them
by the Indenture. 
 5. Optional Redemption. The Notes are subject to redemption, in whole at any time or in part from time to time, at the option of
the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), upon not less than 15 days nor more than 60 days prior
notice as provided in the Indenture. The Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum of the present values of
the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date), discounted to the Redemption Date on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate (as defined below), as determined by the Independent Investment Banker (as defined below), plus 10 basis points, and
(ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date. 

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a
Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the Eighth Supplemental
Indenture. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual
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. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes 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 such Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (A) the arithmetic mean of the
Reference Treasury Dealer Quotations received for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as the “Independent
Investment Banker.”

Securities (USA) LLC, Goldman Sachs & Co. LLC and Wells Fargo Securities, LLC (or their respective affiliates which are primary U.S. Government securities dealers in the United States(“Primary Treasury Dealers”)), and their
respective successors; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s)
selected by the Company. 
 “Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any
Redemption Date, the arithmetic mean, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference
Treasury Dealer at 3:30 p.m. (New York City time) on the third Business Day preceding such Redemption Date. 
 The Company shall give
the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

In connection with any redemption of the Notes in part, if the Notes are represented by one or more Global Notes, interests in the Notes will
be selected for redemption by the Depositary in accordance with its standard procedures therefor. 
 6. Sinking Fund. The Notes are not subject to
any sinking fund or analogous provisions. 
 7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations
of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the
Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service
charge shall be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of
transfer or exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Notes are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any
Notes during the period beginning at the opening of business 15 days before the day of the mailing of the applicable notice of redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or
exchange any Note so selected for redemption in whole or in part (except the unredeemed portion of any Note being redeemed in part). 
 8. Persons Deemed
Owner. The Holder of this Note may be treated as the owner of this Note for all purposes. 
 9. Unclaimed Funds. If money for the payment of
principal, premium or interest of or on the Notes remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment,
Holders entitled to the money must look only to the Company and not to the Trustee or any Paying Agent for payment.

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 Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note
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 Note. 

12. Defaults and Remedies. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared
due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or
for the appointment of a receiver or trustee or for any other remedy thereunder, unless: the Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes; the Holders of not less than 25%
in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days
after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a
majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the
respective due dates expressed herein (including, in case of a redemption, on the Redemption Date). 
 13. Obligations Absolute. No reference herein
to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at the times, place
and rate, and in the coin or currency, herein prescribed. 
 14. No Recourse Against Others. No recourse shall be had for the payment of the
principal of, or premium, if any, or interest on this Note, or for any claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder,
officer or director, as such, past, present or future, of the Company or of any successor corporation, whether by virtue of 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 issue hereof, expressly waived and released.

 15. Trustee Dealings with the Company. Subject to certain limitations imposed by the Trust Indenture Act,
the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the
Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 

16. Successors and Assigns. All covenants and agreements in the Indenture by the Company shall bind its successors and assigns, whether so expressed or
not, except as provided in Section 802 of the Original Indenture.

ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders thereof. No representation is made as to the
accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.

Company shall redeem the Notes upon the terms and subject to the conditions set forth in Section 209 of the Eighth Supplemental Indenture. The Eighth Supplemental Indenture provides that the Company will cause the notice of redemption pursuant

rights, duties and immunities thereunder of the Company, the Trustee and the Holders, and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

This Note is one of the series designated as the “2.550% Senior Notes due 2022” of the Company initially limited in aggregate
principal amount to $1,500,000,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”). Any such
Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date and the
initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided,
however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from
the Notes. Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of the
Company and rank pari passu with all unsecured and unsubordinated obligations of the Company. 
 The terms of the Notes include those stated
in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all those
terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

 5. Optional Redemption. The Notes are subject to redemption, in whole at any time or in part from time to time, at the option of

notice as provided in the Indenture. Prior to the Par Call Date, the Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum
of the present values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date) that would have been due if
the Notes matured on the Par Call Date, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate (as defined below), as determined
by the Independent Investment Banker (as defined below), plus 10 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date. 

On and after the Par Call Date, the Redemption Price for the Notes will equal the sum of (i) 100% of the principal amount of the Notes
then Outstanding to be redeemed and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date. 

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a
Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the Eighth Supplemental
Indenture. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual
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.

maturity comparable to the remaining term of the Notes (assuming the Notes matured on the Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt

(New York City time) on the third Business Day preceding such Redemption Date. 
 With respect to any redemption of the Notes occurring
prior to the Par Call Date, the Company shall give the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

In connection with any redemption of the Notes in part, if the Notes are represented by one or more Global Notes, interests in the Notes will

any Paying Agent for payment. 
 10. Defeasance and Discharge. The Notes will be subject to defeasance and discharge as set forth in

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 Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note
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 Note. 

12. Defaults and Remedies. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared

issue hereof, expressly waived and released. 
 15. Trustee Dealings with the Company. Subject to certain limitations imposed by the Trust Indenture
Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the
Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

“Maturity Date”), and to pay interest thereon from October 13, 2017 (the “Original Issue Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on
January 15 and July 15 in each year (each an “Interest Payment Date”), commencing July 15, 2018, at the rate of 2.930% per annum until the principal hereof is paid or made available for payment. Interest will be
computed on the basis of a 360-day year of twelve 30-day months. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date and on the Maturity Date will, as provided in the Indenture, be paid to the Person in

Maturity Date, as the case may be. If an Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the payment will be made on the next Business Day as if it were made on the date the payment was due, and no interest will
accrue on the amount so payable for the period from and after that Interest Payment Date or the Maturity Date, as the case may be.

(New York City time) on the third Business Day preceding such Redemption Date. 
 With respect to any redemption of the Notes occurring

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 Note. 

12. Defaults and Remedies. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared
due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or
for the appointment of a receiver or trustee or for any other remedy thereunder, unless: the Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes; the Holders of not less than 25%
in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days
after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a
majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the
respective due dates expressed herein (including, in case of a redemption, on the Redemption Date).

any claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or
of any successor corporation, whether by virtue of 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
issue hereof, expressly waived and released. 
 15. Trustee Dealings with the Company. Subject to certain limitations imposed by the Trust Indenture
Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the
Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

not, except as provided in Section 802 of the Original Indenture.

ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 
 18. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders thereof. No representation is made as to the
accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 

19. Special Mandatory Redemption. The Eighth Supplemental Indenture provides that upon the occurrence of a Special Mandatory Redemption Event, the
Company will redeem the Notes upon the terms and subject to the conditions set forth in Section 209 of the Eighth Supplemental Indenture. The Eighth Supplemental Indenture provides that the Company will cause the notice of redemption pursuant

received, hereby promises to pay to [                                  ]‡ [CEDE &

the principal sum of
                               Dollars, on January 15, 2028 (the “Maturity
Date”), and to pay interest thereon from October 13, 2017 (the “Original Issue Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on
January 15 and July 15 in each year (each an “Interest Payment Date”), commencing July 15, 2018, at the rate of 3.250% per annum until the principal hereof is paid or made available for payment. Interest will be
computed on the basis of a 360-day year of twelve 30-day months. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date and on the Maturity Date will, as provided in the Indenture, be paid to the Person in
whose name this Note (or one or more Predecessor Securities to this Note (the “Predecessor Notes”)) is registered at the close of business on the January 1 or July 1 (whether or not a Business Day) (each, a “Regular Record
Date”), as the case may be, next preceding such Interest Payment Date or the Maturity Date, as applicable. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to such Person on such Regular Record
Date and may either be paid to the Holder in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee under the
Indenture, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the
Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount
of interest accrued from and including the immediately preceding Interest Payment Date (or from and including the Original Issue Date, in the case of the initial Interest Payment Date) to but excluding the applicable Interest Payment Date or the
Maturity Date, as the case may be. If an Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the payment will be made on the next Business Day as if it were made on the date the payment was due, and no interest will
accrue on the amount so payable for the period from and after that Interest Payment Date or the Maturity Date, as the case may be. 
 2. Method of
Payment. The Company will pay the principal of and premium, if any, and interest on the Notes in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. [The Company will make
all payments of interest on this Global Note in accordance with the arrangements then existing between the Paying Agent and the Depositary, and all payments of principal of and premium, if any, on this Global Note at the Corporate Trust Office upon
surrender of this Global Note for payment.]** [The Company will make all payments of interest on this Note by mailing a check to the address of the Person entitled thereto, and all payments of

 3. Paying Agent
and Security Registrar. The Trustee shall initially act as the Paying Agent and Security Registrar in respect of the Notes and its Corporate Trust Office is designated as a place where the Notes may be presented for payment or for registration
of transfer or exchange. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to any Holders, and the Company or any Subsidiary may act as Paying Agent or Security Registrar for the Notes. 

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of
November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental Indenture dated as of
March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”) and an Eighth Supplemental Indenture dated as of October 13,
2017 (the “Eighth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture, the “Indenture”), by and between the
Company and The Bank of New York Mellon, as Trustee (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, and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

This Note is one of the series designated as the “3.250% Senior Notes due 2028” of the Company initially limited in aggregate
principal amount to $2,000,000,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”). Any such
Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date and the
initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided,
however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from
the Notes. Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of the
Company and rank pari passu with all unsecured and unsubordinated obligations of the Company. 
 The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all
those terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

 Capitalized terms used but not defined in this Note have the respective meanings ascribed to them

 5. Optional Redemption. The Notes are subject to redemption, in whole at any time or in part from time to time, at the option of
the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), upon not less than 15 days nor more than 60 days prior
notice as provided in the Indenture. Prior to the Par Call Date, the Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum
of the present values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date) that would have been due if
the Notes matured on the Par Call Date, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate (as defined below), as determined
by the Independent Investment Banker (as defined below), plus 15 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date. 

On and after the Par Call Date, the Redemption Price for the Notes will equal the sum of (i) 100% of the principal amount of the Notes
then Outstanding to be redeemed and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date. 

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a
Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the Eighth Supplemental
Indenture. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual
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. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes (assuming the Notes matured on the Par Call Date) 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 such Notes (assuming such Notes matured on the Par Call Date).

however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company. 

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the arithmetic
mean, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 3:30 p.m.
(New York City time) on the third Business Day preceding such Redemption Date. 
 With respect to any redemption of the Notes occurring
prior to the Par Call Date, the Company shall give the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

In connection with any redemption of the Notes in part, if the Notes are represented by one or more Global Notes, interests in the Notes will
be selected for redemption by the Depositary in accordance with its standard procedures therefor. 
 6. Sinking Fund. The Notes are not subject to
any sinking fund or analogous provisions. 
 7. Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations
of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the
Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service
charge shall be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any such registration of
transfer or exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Notes are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any
Notes during the period beginning at the opening of business 15 days before the day of the mailing of the applicable notice of redemption and ending at the close of business on the day of such mailing, or (B) to register the transfer of or
exchange any Note so selected for redemption in whole or in part (except the unredeemed portion of any Note being redeemed in part).

 9. Unclaimed Funds. If money for the payment of principal, premium or interest of or on the Notes remains unclaimed for two years, the
Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee or
any Paying Agent for payment. 
 10. Defeasance and Discharge. The Notes will be subject to defeasance and discharge as set forth in
Section 1302 of the Original Indenture and to covenant defeasance as set forth in Section 1303 of the Original Indenture.

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 Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note
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 Note. 

12. Defaults and Remedies. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared
due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or
for the appointment of a receiver or trustee or for any other remedy thereunder, unless: the Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes; the Holders of not less than 25%
in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days
after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a
majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the
respective due dates expressed herein (including, in case of a redemption, on the Redemption Date).

the principal sum of
                             Dollars, on October 15, 2047 (the “Maturity Date”), and to
pay interest thereon from October 13, 2017 (the “Original Issue Date”), or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on April 15 and October 15
in each year (each an “Interest Payment Date”), commencing April 15, 2018, at the rate of 4.030% per annum until the principal hereof is paid or made available for payment. Interest will be computed on the basis of a 360-day year
of twelve 30-day months. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date and on the Maturity Date will, as provided in the Indenture, be paid to the Person in whose name this Note (or one or more
Predecessor Securities to this Note (the “Predecessor Notes”)) is registered at the close of business on the April 1 or October 1 (whether or not a Business Day) (each, a “Regular Record Date”), as the case may be, next
preceding such Interest Payment Date or the Maturity Date, as applicable. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to such Person on such Regular Record Date and may either be paid to the
Holder in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee under the Indenture, notice whereof shall be
given to Holders of Notes not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such
notice as may be required by such exchange, all as more fully provided in said Indenture. Interest payable on this Note on any Interest Payment Date and on the Maturity Date, as the case may be, will be the amount of interest accrued from and
including the immediately preceding Interest Payment Date (or from and including the Original Issue Date, in the case of the initial Interest Payment Date) to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may
be. If an Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the payment will be made on the next Business Day as if it were made on the date the payment was due, and no interest will accrue on the amount so
payable for the period from and after that Interest Payment Date or the Maturity Date, as the case may be. 
 2. Method of Payment. The Company will
pay the principal of and premium, if any, and interest on the Notes in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. [The Company will make all payments of interest on this
Global Note in accordance with the arrangements then existing between the Paying Agent and the Depositary, and all payments of principal of and premium, if any, on this Global Note at the Corporate Trust Office upon surrender of this Global Note for

 3. Paying Agent
and Security Registrar. The Trustee shall initially act as the Paying Agent and Security Registrar in respect of the Notes and its Corporate Trust Office is designated as a place where the Notes may be presented for payment or for registration
of transfer or exchange. The Company may, however, change the Paying Agent or Security Registrar for the Notes without prior notice to any Holders, and the Company or any Subsidiary may act as Paying Agent or Security Registrar for the Notes. 

4. Indenture. This Note is one of a duly authorized series of Securities issued or to be issued in one or more series under an Indenture dated as of
November 21, 2001 (the “Original Indenture”), as supplemented and amended by a First Supplemental Indenture dated as of July 30, 2009 (the “First Supplemental Indenture”), a Third Supplemental Indenture dated as of
March 30, 2011 (the “Third Supplemental Indenture”), a Fourth Supplemental Indenture dated as of March 30, 2011 (the “Fourth Supplemental Indenture”) and an Eighth Supplemental Indenture dated as of October 13,
2017 (the “Eighth Supplemental Indenture” and, together with the Original Indenture, the First Supplemental Indenture, the Third Supplemental Indenture and the Fourth Supplemental Indenture, the “Indenture”), by and between the
Company and The Bank of New York Mellon, as Trustee (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, and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

This Note is one of the series designated as the “4.030% Senior Notes due 2047” of the Company initially limited in aggregate
principal amount to $2,250,000,000 (the “Notes”). Such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (the “Additional Notes”). Any such
Additional Notes shall have the same ranking, interest rate, maturity date and other terms as the Notes, except, if applicable, the issue date, the issue price, the initial Interest Payment Date and corresponding initial Regular Record Date and the
initial interest accrual date. Any such Additional Notes, together with the Notes, shall constitute a single series of Securities for all purposes under the Indenture, including voting, waivers, amendments and redemptions; provided,
however, that in the event any such Additional Notes are not fungible with the Notes for U.S. federal income tax purposes, such nonfungible Additional Notes shall be issued with a separate CUSIP number so that they are distinguishable from
the Notes. Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of the
Company and rank pari passu with all unsecured and unsubordinated obligations of the Company. 
 The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all those terms, and Holders thereof are referred to the Indenture and the Trust Indenture Act for a statement of all
those terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control. 

  

					
		  	E-5	  	Reverse Side of Form of 4.030% Senior Note due 2047

 Capitalized terms used but not defined in this Note have the respective meanings ascribed to them
by the Indenture. 
 5. Optional Redemption. The Notes are subject to redemption, in whole at any time or in part from time to time, at the option of
the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Note redeemed in part may not be less than $2,000), upon not less than 15 days nor more than 60 days prior
notice as provided in the Indenture. Prior to the Par Call Date, the Redemption Price for the Notes will equal the sum of (i) the greater of (y) 100% of the principal amount of the Notes then Outstanding to be redeemed and (z) the sum
of the present values of the remaining scheduled payments of principal and interest on the Notes then Outstanding to be redeemed (not including any portion of any payments of such interest accrued to the Redemption Date) that would have been due if
the Notes matured on the Par Call Date, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of the Adjusted Treasury Rate (as defined below), as determined
by the Independent Investment Banker (as defined below), plus 20 basis points, and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date. 

On and after the Par Call Date, the Redemption Price for the Notes will equal the sum of (i) 100% of the principal amount of the Notes
then Outstanding to be redeemed and (ii) accrued and unpaid interest on the principal amount of the Notes then Outstanding to be redeemed to, but not including, the Redemption Date. 

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a
Redemption Date will be payable on the Interest Payment Date to the Holders thereof as of the close of business on the corresponding Regular Record Date pursuant to Section 1 of this Note and Section 205 of the Eighth Supplemental
Indenture. 
 “Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual
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. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes (assuming the Notes matured on the Par Call Date) 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 such Notes (assuming such Notes matured on the Par Call Date). 

  

					
		  	E-6	  	Reverse Side of Form of 4.030% Senior Note due 2047

 “Comparable Treasury Price” means, with respect to any Redemption Date, (A) the
arithmetic mean of the Reference Treasury Dealer Quotations received for such Redemption Date, or (B) if only one Reference Treasury Dealer Quotation is received, such quotation. 

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company to act as the “Independent
Investment Banker.” 
 “Par Call Date” means April 15, 2047. 

“Reference Treasury Dealer” means (A) J.P. Morgan Securities LLC, Credit Suisse Securities (USA) LLC, Goldman Sachs &
Co. LLC and Wells Fargo Securities, LLC (or their respective affiliates which are primary U.S. Government securities dealers in the United States(“Primary Treasury Dealers”)), and their respective successors; provided,
however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) selected by the Company. 

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the arithmetic
mean, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 3:30 p.m.
(New York City time) on the third Business Day preceding such Redemption Date. 
 With respect to any redemption of the Notes occurring
prior to the Par Call Date, the Company shall give the Trustee notice of the Redemption Price promptly after the calculation thereof and the Trustee shall have no responsibility for such calculation. 

In connection with any redemption of the Notes in part, if the Notes are represented by one or more Global Notes, interests in the Notes will
be selected for redemption by the Depositary in accordance with its standard procedures therefor. 
  

	6.	Sinking Fund. The Notes are not subject to any sinking fund or analogous provisions. 

 7.
Denominations; Transfer; Exchange. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes in accordance with the Indenture. Every
Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by the Holder thereof or its attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of this Note, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection with any such registration of transfer or exchange, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Notes are to be
redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Notes during the period beginning at the opening of business 15 days before the day of the mailing of the applicable notice of redemption
and ending at the close of business on the day of such mailing, or (B) to register the transfer of or exchange any Note so selected for redemption in whole or in part (except the unredeemed portion of any Note being redeemed in part).

 8. Persons Deemed Owner. The Holder of this Note may be treated as the owner of this Note for all
purposes. 
 9. Unclaimed Funds. If money for the payment of principal, premium or interest of or on the Notes remains unclaimed for two years, the
Trustee or Paying Agent shall pay the money back to the Company at its written request, subject to any applicable abandoned property laws. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee or
any Paying Agent for payment. 
 10. Defeasance and Discharge. The Notes will be subject to defeasance and discharge as set forth in
Section 1302 of the Original Indenture and to covenant defeasance as set forth in Section 1303 of the Original Indenture. 
 11. Amendment;
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 Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note
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 Note. 

12. Defaults and Remedies. If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared
due and payable in the manner and with the effect provided in the Indenture. As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or
for the appointment of a receiver or trustee or for any other remedy thereunder, unless: the Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes; the Holders of not less than 25%
in principal amount of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity; the Trustee for 60 days
after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a
majority in principal amount of the Outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the
respective due dates expressed herein (including, in case of a redemption, on the Redemption Date). 

  

					
		  	E-8	  	Reverse Side of Form of 4.030% Senior Note due 2047

 13. Obligations Absolute. No reference herein to the Indenture and no provision of this Note or of the

 14. No Recourse Against Others. No recourse shall be had for the payment of the principal of, or premium, if any, or interest on this Note, or for
any claim based hereon or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or
of any successor corporation, whether by virtue of 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
issue hereof, expressly waived and released. 
 15. Trustee Dealings with the Company. Subject to certain limitations imposed by the Trust Indenture
Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the
Company or its Affiliates with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 

16. Successors and Assigns. All covenants and agreements in the Indenture by the Company shall bind its successors and assigns, whether so expressed or
not, except as provided in Section 802 of the Original Indenture. 
 17. Governing Law. THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 
 18. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and has directed the Trustee to use CUSIP numbers in notices of redemption as a convenience to Holders thereof. No representation is made as to the
accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 

19. Special Mandatory Redemption. The Eighth Supplemental Indenture provides that upon the occurrence of a Special Mandatory Redemption Event, the
Company will redeem the Notes upon the terms and subject to the conditions set forth in Section 209 of the Eighth Supplemental Indenture. The Eighth Supplemental Indenture provides that the Company will cause the notice of redemption pursuant
to Section 209 of the Eighth Supplemental Indenture to be sent to each Holder, with a copy to the Trustee, within five Business Days after the occurrence of a Special Mandatory Redemption Event.
