previously defined, is concerned; 
 (e) the singular includes the plural and vice versa; 

(f) headings are for convenience of reference only and do not affect interpretation; and

on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be
made on the immediately preceding Business Day, in each case with the same force and effect as if made on the date the payment was originally payable.

 SECTION 1.04 Denominations. 

The Senior Notes may be issued in denominations of $2,000, or any integral multiple of $1,000 in excess thereof. 

SECTION 1.05 Global Securities. 

(a) Except under the limited circumstances described below, Senior Notes represented by Global Securities will not be exchangeable for, and
will not otherwise be issuable as, Senior Notes in definitive form. The Global Securities described above may not be transferred except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or to a successor Depositary or its nominee. 
 (b) Except as otherwise provided in this Thirty-Seventh
Supplemental Indenture, owners of beneficial interests in such Global Securities will not be considered the holders thereof for any purpose under the Indenture, and no Global Security representing a Senior Note shall be exchangeable, except for
another Global Security of like denomination and to be registered in the name of the Depositary or its nominee or to a successor Depositary or its nominee. The rights of holders of such Global Securities shall be exercised only through the
Depositary. 
 (c) A Global Security shall be exchangeable in whole or, from time to time, in part for Senior Notes in definitive registered
form only as provided in the Indenture. If (i) at any time the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the Senior Notes or if at any time the Depositary shall no longer be registered or in
good standing as a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, at such time as the Depositary is required to be
so registered and the Depositary so notifies the Company and, in each case, the Company does not appoint a successor Depositary within 90 days after the Company receives such notice or becomes aware of such condition, as the case may be,
(ii) any Event of Default or Default has occurred and is continuing with respect to the Senior Notes or (iii) subject to the procedures of the Depositary, the Company in its sole discretion determines that the Senior Notes shall be
exchangeable for Senior Notes in definitive registered form and executes and, in each case, delivers to the Security Registrar a written order of the Company providing that the Senior Notes shall be so exchangeable, the Senior Notes shall be
exchangeable for Senior Notes in definitive registered form, provided that the definitive Senior Notes so issued in exchange for the Senior Notes shall be in denominations of $2,000, or any integral multiple of $1,000 in excess thereof, and
be of like aggregate principal amount and tenor as the portion of the Senior Notes to be exchanged. Except as provided herein, owners of beneficial interests in the Senior Notes will not be entitled to have Senior Notes registered in their names,
will not receive or be entitled to physical delivery of Senior Notes in definitive registered form and will not be considered the holders thereof for any purpose under the Indenture. Neither the Company, the Trustee, any Paying Agent nor the
Security Registrar shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the Senior Notes, or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests. Any Global Security that is exchangeable pursuant to this Section 1.05(c) shall be exchangeable for Senior Notes registered in such names as the Depositary shall direct. 

  
 - 4 - 












 SECTION 1.06 Transfer. 

The Trustee is hereby designated as Security Registrar for the Senior Notes. No service charge will be made for any registration of transfer
or exchange of Senior Notes, but payment will be required of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. 

SECTION 1.07 Defeasance. 

The provisions of Sections 13.02 and 13.03 of the Original Indenture will apply to the Senior Notes. 

SECTION 1.08 Redemption at the Option of the Company. 

(a) Prior to July 15, 2053 (six months prior to the Stated Maturity Date) (the “Par Call Date”), The Company may redeem the
Senior Notes at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: 

(i) (1) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the
Redemption Date (assuming the Senior Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the
Treasury Rate plus 25 basis points less (2) interest accrued to the date of redemption, and 
 (ii) 100% of the
principal amount of the Senior Notes to be redeemed, 
 plus, in either case, accrued and unpaid interest thereon to the
Redemption Date. 
 (b) On or after the Par Call Date, the Company may redeem the Senior Notes, in whole or in part, at any time and from
time to time, at a Redemption Price equal to 100% of the principal amount of the Senior Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date. 

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the
following two paragraphs. 
 (i) The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or
after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that
appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected 

  
 - 5 - 












 
Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant
maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the
Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant
maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual
number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity
on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such
Treasury constant maturity from the Redemption Date. 
 (ii) If on the third Business Day preceding the Redemption Date H.15
or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second
Business Day preceding such Redemption Date of the U.S. Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no U.S. Treasury security maturing on the Par Call Date but there are two or
more U.S. Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the U.S. Treasury
security with a maturity date preceding the Par Call Date. If there are two or more U.S. Treasury securities maturing on the Par Call Date or two or more U.S. Treasury securities meeting the criteria of the preceding sentence, the Company shall
select from among these two or more U.S. Treasury securities the U.S. Treasury security that is trading closest to par based upon the average of the bid and asked prices for such U.S. Treasury securities at 11:00 a.m., New York City time. In
determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable U.S. Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of
principal amount) at 11:00 a.m., New York City time, of such U.S. Treasury security, and rounded to three decimal places. 
 (c) The
Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. 

(d) Notwithstanding Section 3.02 of the Original Indenture, the notice of redemption with respect to any redemption pursuant to
Section 1.08(a) need not set forth the Redemption Price but only the manner of calculation thereof as described above. 

  
 - 6 - 












 (e) The Company shall notify the Trustee of the Redemption Price with respect to any
redemption pursuant to Section 1.08(a) promptly after the calculation thereof. The Trustee shall not be responsible for calculating said Redemption Price. 

(f) If less than all of the Senior Notes are to be redeemed, the Trustee shall select the Senior Notes or portions of the Senior Notes to be
redeemed by such method as the Trustee shall deem fair and appropriate. The Trustee may select for redemption Senior Notes and portions of Senior Notes in amounts of $1,000 and integral multiples of $1,000 in excess thereof (provided that the
unredeemed portion of any Senior Note to be redeemed in part will not be less than $2,000) and shall thereafter promptly notify the Company in writing of the numbers of Senior Notes to be redeemed, in whole or in part; provided that if the
Senior Notes are represented by one or more Global Securities, interests in such Global Securities shall be selected for redemption by the Depositary in accordance with its standard procedures therefor. 

SECTION 1.09 No Sinking Fund. 

The Senior Notes shall not be entitled to any sinking fund. 

ARTICLE II 

MISCELLANEOUS PROVISIONS

Notes. To the extent the terms of the Original Indenture are amended by any of such other supplemental indentures, no such amendment shall relate or apply to the Senior Notes. To the extent the terms of the Original Indenture are amended as provided
herein, no such amendment shall in any way affect the terms of any such other supplemental indenture or any other series of Securities. This Thirty-Seventh Supplemental Indenture shall relate and apply solely to the Senior Notes. 

SECTION 2.02 Trustee Not Responsible for Recitals. 

The recitals herein contained are made by the Company and not by the Trustee, and the Trustee assumes no responsibility for the correctness
thereof. The Trustee makes no representation as to the validity or sufficiency of this Thirty-Seventh Supplemental Indenture or the Senior Notes. 

SECTION 2.03 Ratification and Incorporation of Original Indenture. 

As supplemented hereby, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture and this Thirty-Seventh

This Thirty-Seventh Supplemental Indenture shall be deemed to be a contract made under the internal laws of the State of New York, and for all
purposes shall be construed in accordance with the laws of said State. 
 SECTION 2.05 Separability. 

In case any one or more of the provisions contained in this Thirty-Seventh Supplemental Indenture or in the Senior Notes shall for any reason
be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Thirty-Seventh Supplemental Indenture or of the Senior Notes, but this Thirty-Seventh
Supplemental Indenture and the Senior Notes shall be construed as if such invalid or illegal or unenforceable provision had never been contained herein or therein. 

SECTION 2.06 Executed in Counterparts. 

This Thirty-Seventh Supplemental Indenture may be executed in any number of counterparts, each of which shall be an original; but such
counterparts shall together constitute but one and the same instrument. The words “execution,” “signed,” “signature,” and words of like import in this Thirty-Seventh Supplemental Indenture shall include images of
manually executed signatures transmitted by facsimile or other electronic format (including, without limitation, “pdf”, “tif” or “jpg”) and other electronic signatures (including, without limitation, DocuSign and
AdobeSign). The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect,
validity and enforceability as a manually executed signature or use of a paper- based record-keeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New
York State Electronic Signatures and Records Act, and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code. For the avoidance of doubt and only with
respect to the Senior Notes, this Section shall be deemed to amend Section 2.04 of the Indenture to permit (i) electronic signatures of the Senior Notes by the officers specified therein and attested to by the Secretary or Assistant
Secretary without affixation of the corporate seal thereto and (ii) authentication by the Trustee to be executed by manual, electronic or facsimile signature and provide that any Senior Note executed, authenticated and delivered in such manner
shall be valid and obligatory for all purposes under the Indenture and entitled to the benefits thereunder and hereunder.

Trust Company, National Association (as successor to Bank One Trust Company, N.A.)), as trustee (the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental
thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the holders of the Senior Notes issued thereunder and of the terms upon which said
Senior Notes are, and are to be, authenticated and delivered. This Senior Note is one of the series designated on the face hereof as the 5.250% Senior Notes due 2054, initially limited in aggregate principal amount of $1,000,000,000;
provided, however, that (subject to the provisions of the Thirty-Seventh Supplemental Indenture) the aggregate principal amount of the Senior Notes may be increased in the future with no limit, without the consent of the holders of the
Senior Notes, on the same terms and with the same CUSIP and ISIN numbers as the Senior Notes, except for the issue price, Original Issue Date and, if applicable, the first Interest Payment Date and the initial interest accrual date, provided
that no Event of Default with respect to the Senior Notes shall have occurred and be continuing. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture. 

2. This Senior Note is exchangeable in whole or, from time to time, in part for Senior Notes in definitive registered form only as provided
herein and in the Indenture. If (i) at any time the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for this Senior Note or if at any time the Depositary shall no longer be registered or in good standing
as a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, at such time as the Depositary is required to be so registered
and the Depositary so notifies the Company and, in each case, the Company does not appoint a successor Depositary within 90 days after the Company receives such notice or becomes aware of such condition, as the case may be, (ii) any Event of
Default or Default has occurred and is continuing with respect to the Senior Notes or (iii) subject to the procedures of the Depositary, the Company in its sole discretion determines that this Senior Note shall be exchangeable for Senior Notes
in definitive registered form and executes and delivers to the Security Registrar a written order of the Company providing that this Senior Note shall be so exchangeable, this Senior Note shall be exchangeable for Senior Notes in definitive
registered form, provided that the definitive Senior Notes so issued in exchange for this Senior Note shall be in denominations of $2,000 and integral multiples of $1,000 in excess thereof and be of like aggregate principal amount and tenor
as the portion of this Senior Note to be exchanged. Except as provided above or in the Thirty-Seventh Supplemental Indenture, owners of beneficial interests in this Senior Note will not be entitled to have Senior Notes registered in their names,
will not receive or be entitled to physical delivery of Senior Notes in definitive registered form and will not be considered the holders thereof for any purpose under the Indenture. Neither the Company, the Trustee, any Paying Agent nor the
Security Registrar shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in this Senior Note, or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests.

 3. If an Event of Default with respect to the Senior Notes shall occur and be continuing,
the principal of the Senior Notes may be declared due and payable in the manner, with the effect and subject to the conditions provided in the Indenture. 

4. 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 under the Indenture at any time by the Company and the Trustee with the consent of the holders of not less than a majority in aggregate 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 Senior Notes at the time Outstanding, on behalf of the holders of all Senior Notes,
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 Senior Note shall be conclusive and binding upon such
holder and upon all future holders of this Senior Note and of any Senior Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Senior Note.

 5. The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of the Company pursuant to this
Senior Note and (b) restrictive covenants and the related Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Senior Note. 

6. (a) Prior to July 15, 2053 (six months prior to the Stated Maturity Date) (the “Par Call Date”), The Company may redeem
the Senior Notes at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: 

(i) (1) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to
the Redemption Date (assuming the Senior Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the
Treasury Rate plus 25 basis points less (2) interest accrued to the date of redemption, and 
 (ii) 100% of the
principal amount of the Senior Notes to be redeemed, 
 plus, in either case, accrued and unpaid interest thereon to the
Redemption Date. 
 (b) On or after the Par Call Date, the Company may redeem the Senior Notes, in whole or in part, at any time and from
time to time, at a Redemption Price equal to 100% of the principal amount of the Senior Notes being redeemed plus accrued and unpaid interest thereon to the Redemption Date. 

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the
following two paragraphs. 

  
 A-7 













	(i)	 The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as
yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such
time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication)
(“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable:
(1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly
equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining
Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15
shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be
deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date. 


  

	(ii)	 If on the third Business Day preceding the Redemption Date H.15 or any successor designation or publication is
no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the
U.S. Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no U.S. Treasury security maturing on the Par Call Date but there are two or more U.S. Treasury securities with a maturity date
equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the U.S. Treasury security with a maturity date preceding the Par Call
Date. If there are two or more U.S. Treasury securities maturing on the Par Call Date or two or more U.S. Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more U.S. Treasury
securities the U.S. Treasury security that is trading closest to par based upon the average of the bid and asked prices for such U.S. Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the
terms of this paragraph, the semi-annual yield to maturity of the applicable U.S. Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of
such U.S. Treasury security, and rounded to three decimal places. 


 7. The Company’s actions and determinations in
determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error. 

  
 A-8 












 8. The Trustee shall not be responsible for calculating the Redemption Price with respect to
any redemption occurring prior to the Par Call Date. 
 9. If less than all of the Senior Notes are to be redeemed, the Trustee shall select
the Senior Notes or portions of Senior Notes to be redeemed by such method as the Trustee shall deem fair and appropriate. The Trustee may select for redemption Senior Notes and portions of Senior Notes in amounts of $1,000 and integral multiples of
$1,000 in excess thereof (provided that the unredeemed portion of any Senior Note to be redeemed in part will not be less than $2,000) and shall thereafter promptly notify the Company in writing of the numbers of Senior Notes to be redeemed,
in whole or in part; provided that if the Senior Notes are represented by one or more Global Securities, interests in such Global Securities shall be selected for redemption by the Depositary in accordance with its standard procedures
therefor. 
 10. No reference herein to the Indenture and no provision of this Senior 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 due on this Senior Note at the time, place and rate, and in the coin or currency, herein prescribed. 

11. (a) As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Senior Note is registrable in
the Security Register, upon surrender of this Senior Note for registration of transfer at the office or agency of the Company for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company
or the Security Registrar and duly executed by, the holder hereof or his attorney duly authorized in writing, and thereupon one or more new Senior Notes, of authorized denominations and of like tenor and for the same aggregate principal amount, will
be issued to the designated transferee or transferees. No service charge shall be made for any such exchange or registration of transfer, but the Company will require payment of a sum sufficient to cover any tax or other governmental charge payable
in connection therewith. 
 (b) Prior to due presentment of this Senior Note for registration of transfer, the Company, the Trustee, any
Paying Agent and the Security Registrar of the Company or the Trustee may deem and treat the Person in whose name this Senior Note is registered as the absolute owner hereof for all purposes (subject to Section 1.03(a) of the Thirty-Seventh
Supplement Indenture), whether or not this Senior Note be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the Security Registrar, and neither the Company nor the Trustee nor any Paying Agent nor the
Security Registrar shall be affected by notice to the contrary. Except as provided in Section 1.03(a) of the Thirty-Seventh Supplemental Indenture, all payments of the principal of and premium, if any, and interest due on this Senior Note made
to or upon the order of the registered holder hereof shall, to the extent of the amount or amounts so paid, effectually satisfy and discharge liability for moneys payable on this Senior Note. 

(c) The Senior Notes are issuable only in registered form without coupons in denominations of $2,000, or any integral multiple of $1,000 in
excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes of a different authorized denomination, as requested by the holder
surrendering the same upon surrender of the Senior Note or Senior Notes to be exchanged at the office or agency of the Company.

 12. No recourse shall be had for payment of the principal of, or premium, if any, or
interest on this Senior Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past, present or future, as such, of the Company or
of any predecessor or 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 issuance hereof, expressly waived and released. 
 13. This Senior Note shall be deemed to be a contract made under
the internal laws of the State of New York, and for all purposes shall be construed in accordance with laws of said State.
