 ARTICLE 5. 

MISCELLANEOUS 

Section 5.1.    Ratification of Indenture. The Indenture, as supplemented by this Supplemental Indenture, is
in all respects ratified, confirmed and binding upon the parties hereto, and this Supplemental Indenture shall be deemed part of the Indenture in the manner and to the extent herein and therein provided; provided, however, that the
provisions of this Supplemental Indenture shall apply solely with respect to the Notes. 

Section 5.2.    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 Supplemental Indenture. 

Section 5.3.    Governing Law. This Supplemental Indenture and each Note shall be governed by, and construed
in accordance with, the laws of the State of New York. 
 Section 5.4.    Separability. In case any one or
more of the provisions contained in the Indenture, this Supplemental Indenture or the 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 the Indenture, this Supplemental Indenture or the Notes, but the Indenture, this Supplemental Indenture and the Notes shall be construed as if such invalid or illegal or unenforceable provision had never been contained herein or
therein. 
 Section 5.5.    Counterparts. This 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. 

Section 5.6.    Electronic Means. The Trustee shall have the right to accept and act upon instructions,
including funds transfer instructions (“Instructions”) given pursuant to this Supplemental Indenture and the Notes and delivered using Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency
certificate listing officers with the authority to provide such Instructions (“Authorized Officers”) and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company whenever a
person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its discretion elects to act upon such Instructions, the Trustee’s understanding of such
Instructions shall be deemed controlling. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to
have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to
the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. The Trustee
shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written
instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of
interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting
Instructions than the method(s) selected by the Company; (iii) that the security procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its
particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

 [REVERSE OF NOTE] 

This Note is one of a duly authorized issue of securities of the Company (herein called the “Notes”), issued under an
Indenture, dated as of May 18, 2009, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee, and a fourteenth supplemental indenture relating to such series dated as of March 17, 2021 (herein, collectively called
the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee,” which term
includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the
Securities and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof, such series initially limited in aggregate principal amount to $[●];
provided that the Company may at any time and from time to time, without the consent of any Holder, issue additional Notes of this series. 

The Notes of this series are not redeemable at the option of the Holders. 

At any time prior to September 17, 2051, the Notes shall be redeemable in whole or in part, at any time or from time to time, at the
Company’s option, on at least 10 days’ but not more than 60 days’ prior notice mailed to the registered address of each Holder of Notes to be redeemed, at a redemption price (the “Make-Whole Redemption Price”),
calculated by the Company, equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of each remaining scheduled payment of principal and interest on the Notes to be redeemed
(assuming for such purposes that the Notes mature on September 17, 2051) (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Treasury Rate plus 12.5 basis points. 
 At any time
on or after September 17, 2051, the Notes shall be redeemable in whole or in part, at any time, at the Company’s option, on at least 10 days’ but not more than 60 days’ prior notice mailed to the registered address of each Holder
of Notes to be redeemed, at a redemption price (the “Final Redemption Price” and, together with the Make-Whole Redemption Price, the “Redemption Price”) equal to 100% of the principal amount of the Notes to be
redeemed. 
 The Redemption Price for any Notes redeemed pursuant to the two preceding paragraphs shall include accrued and unpaid interest
on the principal amount of such Notes to the Redemption Date. 
 For purposes of calculating the Make-Whole Redemption Price, the following
terms shall have the following specified meanings: 
 “Comparable Treasury Issue” means the United States Treasury security
or securities selected by an Independent Investment Banker as having an actual or interpolated 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 a comparable maturity to the remaining term of the Notes (assuming for such purposes that the Notes mature on September 17, 2051). 

  
 A-5 













 “Comparable Treasury Price” means, with respect to any Redemption Date
(A) the arithmetic average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations or (B) if the Company obtains fewer than four such Reference
Treasury Dealer Quotations, the arithmetic average of all such quotations for such Redemption Date. 
 “Independent Investment
Banker” means one of the Reference Treasury Dealers appointed by the Company. 
 “Reference Treasury Dealer” means
Morgan Stanley & Co. LLC and Wells Fargo Securities, LLC or their respective affiliates, which are primary U.S. government securities dealers in the United States of America and their respective successors plus two other primary U.S. government
securities dealers in the United States of America designated by the Company; provided, however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer in the United States of America (a
“Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer. 
 “Reference
Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the arithmetic average, as determined by the Company, of the bid and asked prices for the applicable 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. 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to
maturity or interpolated maturity (on a day count basis) of the applicable Comparable Treasury Issue, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury
Price for such Redemption Date. 
 The provisions of Article XI of the Indenture shall apply to any redemption of the Notes. 

The Notes of this series are not entitled to the benefit of any sinking fund. 

The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Notes of this series or certain restrictive
covenants and Events of Default with respect to such Notes, in each case upon compliance with certain conditions set forth in the Indenture. 

If an Event of Default with respect to Notes of this series shall occur and be continuing, the principal of such Notes may be declared, or
shall immediately become, due and payable in the manner and with the effect provided in the Indenture. 
 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 Notes 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 aggregate principal 

  
 A-6 













 
amount of the Notes at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of
the Notes of each series at the time Outstanding, on behalf of the Holders of all Notes 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 Holders of Notes of this series shall be conclusive and binding upon such Holders 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. 
 As provided in and subject to the provisions of
the Indenture, the Holders of the Notes of this series 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 such Holder shall
have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes of this series, the Holders of not less than 25% in aggregate principal amount of the Notes of this series 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, and the Trustee shall not have received from the Holders of a majority in aggregate principal
amount of such Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply

 [REVERSE OF NOTE] 

This Note is one of a duly authorized issue of securities of the Company (herein called the “Notes”), issued under an
Indenture, dated as of May 18, 2009, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee, and a fourteenth supplemental indenture relating to such series dated as of March 17, 2021 (herein, collectively called
the “Indenture,” which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee,” which term
includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the
Securities and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof, such series initially limited in aggregate principal amount to $[●];
provided that the Company may at any time and from time to time, without the consent of any Holder, issue additional Notes of this series. 

The Notes of this series are not redeemable at the option of the Holders. 

At any time prior to September 17, 2061, the Notes shall be redeemable in whole or in part, at any time or from time to time, at the
Company’s option, on at least 10 days’ but not more than 60 days’ prior notice mailed to the registered address of each Holder of Notes to be redeemed, at a redemption price (the “Make-Whole Redemption Price”),
calculated by the Company, equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of each remaining scheduled payment of principal and interest on the Notes to be redeemed
(assuming for such purposes that the Notes mature on September 17, 2061) (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Treasury Rate plus 12.5 basis points. 
 At any
time on or after September 17, 2061, the Notes shall be redeemable in whole or in part, at any time, at the Company’s option, on at least 10 days’ but not more than 60 days’ prior notice mailed to the registered address of
each Holder of Notes to be redeemed, at a redemption price (the “Final Redemption Price” and, together with the Make-Whole Redemption Price, the “Redemption Price”) equal to 100% of the principal amount of the Notes
to be redeemed. 
 The Redemption Price for any Notes redeemed pursuant to the two preceding paragraphs shall include accrued and unpaid
interest on the principal amount of such Notes to the Redemption Date. 
 For purposes of calculating the Make-Whole Redemption Price, the
following terms shall have the following specified meanings: 
 “Comparable Treasury Issue” means the United States
Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated 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 a comparable maturity to the remaining term of the Notes (assuming for such purposes that the Notes mature on September 17, 2061). 

  
 B-5 













 “Comparable Treasury Price” means, with respect to any Redemption Date
(A) the arithmetic average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations or (B) if the Company obtains fewer than four such Reference
Treasury Dealer Quotations, the arithmetic average of all such quotations for such Redemption Date. 
 “Independent Investment
Banker” means one of the Reference Treasury Dealers appointed by the Company. 
 “Reference Treasury Dealer” means
Morgan Stanley & Co. LLC and Wells Fargo Securities, LLC or their respective affiliates, which are primary U.S. government securities dealers in the United States of America and their respective successors plus two other primary U.S. government
securities dealers in the United States of America designated by the Company; provided, however, that if any of the foregoing shall cease to be a primary U.S. government securities dealer in the United States of America (a
“Primary Treasury Dealer”), the Company shall substitute therefor another Primary Treasury Dealer. 
 “Reference
Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the arithmetic average, as determined by the Company, of the bid and asked prices for the applicable 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. 

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to
maturity or interpolated maturity (on a day count basis) of the applicable Comparable Treasury Issue, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury
Price for such Redemption Date. 
 The provisions of Article XI of the Indenture shall apply to any redemption of the Notes. 

The Notes of this series are not entitled to the benefit of any sinking fund. 

The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Notes of this series or certain restrictive
covenants and Events of Default with respect to such Notes, in each case upon compliance with certain conditions set forth in the Indenture. 

If an Event of Default with respect to Notes of this series shall occur and be continuing, the principal of such Notes may be declared, or
shall immediately become, due and payable in the manner and with the effect provided in the Indenture. 
 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 Notes 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 aggregate principal 

  
 B-6 













 
amount of the Notes at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of
the Notes of each series at the time Outstanding, on behalf of the Holders of all Notes 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 Holders of Notes of this series shall be conclusive and binding upon such Holders 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. 
 As provided in and subject to the provisions of
the Indenture, the Holders of the Notes of this series 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 such Holder shall
have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes of this series, the Holders of not less than 25% in aggregate principal amount of the Notes of this series 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, and the Trustee shall not have received from the Holders of a majority in aggregate principal
amount of such Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. 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. 

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 any premium and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security
Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Note are payable, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes of this series and of like tenor, of authorized
denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The Notes of this
series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Notes of this series are
exchangeable for a like principal amount of Notes of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.
