	201.	 Establishment and Designation of the Notes 

Pursuant to the terms hereof and Section 301 of the Original Indenture, the Company hereby establishes three new series of Securities, the
first series designated as the “4.400% Senior Notes due 2030,” the second series designated as the “5.150% Senior Notes due 2040,” and the third series designated as the “5.250% Senior Notes due 2050.”
Any such series may be reopened, from time to time, for issuances of an unlimited aggregate principal amount of additional Securities of such series (with respect to such series, the “Additional Notes”). Any such Additional Notes
shall have the same ranking, interest rate, maturity date and other terms of the series being reopened, 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 of the series being reopened, 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 of the series being reopened 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 of the series being reopened. 
  

	202.	 Principal Amount of the Notes; Maturity 

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 Notes) is $750,000,000 in respect of the

  
 3 

 
2030 Notes, $500,000,000 in respect of the 2040 Notes and $1,000,000,000 in respect of the 2050 Notes. The principal amount of the 2030 Notes shall be due and payable on May 1, 2030,
the principal amount of the 2040 Notes shall be due and payable on May 1, 2040 and the principal amount of the 2050 Notes shall be due and payable on May 1, 2050. 
  

	203.	 Form of Notes; Denominations; Depositary

the form set forth in Exhibit A hereto, the 2040 Notes shall be initially issued in the form of one or more Global Securities (the “2040 Global Notes”) in substantially the form set forth in
Exhibit B hereto and the 2050 Notes shall be initially issued in the form of one or more Global Securities (the “2050 Global Notes” and, together with the 2030 Global Notes and the 2040 Global Notes,
the “Global Notes”) in substantially the form set forth in Exhibit C hereto. The Notes shall be issued in fully registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in
excess thereof. 
 The initial Depositary in respect of the Global Notes shall be The Depository Trust Company. The Global Notes shall be
deposited with, or on behalf of, the Depositary and shall be registered in the name of Cede & Co. Except as otherwise set forth in Section 305 of the Original Indenture, the Global Notes may be transferred, in whole or in part, only to
the Depositary, another nominee of the Depositary or to a successor of the Depositary or its nominee. 
  

	204.	 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 any Global Note in accordance with the arrangements then existing between the Paying Agent and the applicable Depositary, and all
payments of principal of and premium, if any, on any Global Note at the Corporate Trust Office upon surrender of such Note for payment. The Company will make all payments of interest on any definitive Note by mailing a check to the address of each
Person entitled thereto, and all payments of principal of and premium, if any, on any definitive Note at the Corporate Trust Office upon surrender of such Note for payment. 
  

	205.	 Interest Rate 

Interest on the 2030 Notes shall accrue at the rate of 4.400% per annum, interest on the 2040 Notes shall accrue at the rate of 5.150% per
annum and interest on the 2050 Notes shall accrue at the rate of 5.250% per annum. Interest on the Notes shall accrue from March 23, 2020 or the most recent Interest Payment Date to which interest was paid or duly provided for. Interest on
the 2030 Notes, the 2040 Notes and the 2050 Notes shall be payable semiannually in arrears on May 1 and November 1, commencing on November 1, 2020 (each an “Interest Payment Date” for the 2030 Notes, the 2040 Notes
and the 2050 Notes), to the Persons in whose names such Notes are registered at the close of business on the April 15 or October 15, as the case may be (in either case, whether or not a Business Day), immediately preceding such Interest
Payment Date (each a “Regular Record Date” for the 2030 Notes, the 2040 Notes and the 2050 Notes). Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

or any Subsidiary may act as Paying Agent or Security Registrar for the Notes. 
  

	207.	 No Sinking Fund 

The provisions of Article 12 of the Original Indenture shall not be applicable to the Notes. 

 

	208.	 Optional Redemption

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.

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 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 and discharge of the Indenture.

principal sum of                             
Dollars, on May 1, 2030 (the “Maturity Date”), and to pay interest thereon from March 23, 2020 (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 May 1 and November 1 in each year (each an “Interest Payment Date”), commencing November 1, 2020, at the rate of 4.400% 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 15 or October 15 (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

principal amount to $750,000,000 (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, as a whole or in part, at any time or
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), on at least 15 days
but not 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 that would have been due if the Notes matured on the Par Call Date (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 50 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 Ninth 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). 

“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.

(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.

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

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

being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

2040 (the “Maturity Date”), and to pay interest thereon from March 23, 2020 (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 May 1 and November 1 in each year (each an “Interest Payment Date”), commencing November 1, 2020, at the rate of 5.150% 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”))

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

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 “5.150% Senior Notes due 2040” of the Company initially limited in aggregate
principal amount to $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,

Additional series of Securities may be issued pursuant to the Indenture. 
 The Notes are unsecured senior obligations of the Company and

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.

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.

Indenture.

 With respect to any redemption of the Notes occurring

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

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.

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.

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.

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. 

The Company will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to:

principal sum of                             
Dollars, on May 1, 2050 (the “Maturity Date”), and to pay interest thereon from March 23, 2020 (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 May 1 and November 1 in each year (each an “Interest Payment Date”), commencing November 1, 2020, at the rate of 5.250% 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 April 15 or October 15 (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.]17 [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 principal of and premium, if any, on
this Note at the Corporate Trust Office upon surrender of this Note for payment.]18

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 a
Ninth Supplemental Indenture dated as of March 23, 2020 (the “Ninth 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 “5.250% Senior Notes due 2050” 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, as a whole or in part, at any time or
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), on at least 15 days
but not 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 that would have been due if the Notes matured on the Par Call Date (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 50 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 Ninth 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). 

“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.

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.

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. 

11.    Amendment; Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the

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
