 For and in consideration of the promises and the purchase of the 2033 Senior Notes by the Holders

 Section 1. The Original Indenture is hereby amended solely with
respect to the 2033 Senior Notes as follows: 
  

	 	(A)	 By amending Section 101 to insert the following definitions in their entirety in the appropriate
alphabetical order as follows: 


 “Change of Control” means the occurrence of any one of the following:
(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the Company’s and its subsidiaries
assets taken as a whole to any Person other than to the Company or a Subsidiary; (2) the consummation of any transaction (including without limitation, any merger or consolidation) the result of which is that any Person becomes the
“beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of
the Company or the Voting Stock of any Parent Company (as defined below) or other Voting Stock into which the Voting Stock of the Company or the Voting Stock of any Parent Company is reclassified, consolidated, exchanged or changed, measured by
voting power rather than number of shares; (3) the Company or any Parent Company consolidates with, or merges with or into, any Person, or any Person consolidates with, or merges with or into, the Company or any Parent Company, in any such
event pursuant to a transaction in which any of the outstanding Voting Stock of the Company, the Voting Stock of such Parent Company or the Voting Stock of such other Person is converted into or exchanged for cash, securities or other property,
other than any such transaction where the shares of the Voting Stock of the Company or the Voting Stock of such Parent Company outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the
Voting Stock of the surviving Person or any Parent Company of the surviving Person immediately after giving effect to such transaction; or (4) the adoption of a plan relating to the liquidation or dissolution of the Company. Notwithstanding the
foregoing, a transaction will not be deemed to involve a Change of Control under clause (2) above if (i) the Company becomes a subsidiary of a Parent Company and (ii) the holders of the Voting Stock of the Company or the Voting Stock
of any Parent Company immediately prior to such transaction hold at least a majority of the Voting Stock of such Parent Company immediately following such transaction; provided that any series of related transactions shall be treated as a single
transaction. The term “Person,” solely as used in this definition, has the meaning given thereto in Section 13(d)(3) of the Exchange Act. 

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

“Common Stock” means, with respect to any Principal Subsidiary, Capital Stock of any class, however designated, except Capital Stock
which is non-participating beyond fixed dividend and liquidation preferences and the holders of which have either no voting rights or limited voting rights entitling them, only in the case of certain
contingencies, to elect less than a majority of the directors (or persons performing similar functions) of such Principal Subsidiary, and also includes securities of any class, however designated, which are convertible into Common Stock. 

  
 2 












 “Electronic Means” means the following communications methods: e-mail, facsimile transmission, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the
Trustee as available for use in connection with its services hereunder. 
 “Indebtedness” means, with respect to any Person
(without duplication): 
 (1) any liability of that Person (A) for borrowed money, or under any reimbursement obligation relating to a
letter of credit or similar instrument; (B) evidenced by a bond, note, debenture or similar instrument; (C) to pay the deferred purchase price of property or services, except trade accounts payable arising in the ordinary course of
business; or (D) for the payment of money relating to any obligations under any capital lease of real or personal property which has been recorded as a capitalized lease obligation; 

(2) any liability of others described in the preceding clause (1) that the Person has guaranteed or that is otherwise its legal liability
or which is secured by a lien on that Person’s Property; and 
 (3) any amendment, supplement, modification, deferral, renewal,
extension or refunding of any liability of the types referred to in clauses (1) or (2) above. 
 “Investment Grade” means a
rating of Baa3 or better by Moody’s (or its equivalent under any successor rating category) and a rating of BBB- or better by S&P Global Ratings (or its equivalent under any successor rating
category). 
 “Issue Date” means the first date on which 2033 Senior Notes are issued, which shall be November 22, 2022. 

“Moody’s” means Moody’s Investors Service, Inc., or any successor thereto. 

“Parent Company” means any holding company that, directly or indirectly, owns 100% of the Voting Stock of the Company. 

“Principal Subsidiary” means a consolidated subsidiary of the Company that, as of the relevant time of determination, is a
“significant subsidiary” as defined under Rule 405 under the Securities Act of 1933, as amended (as that Rule is in effect on November 7, 2022, without giving effect to any further amendment of that Rule). 

“Rating Agency” means: 

  
 3 












 (1) each of Moody’s and S&P Global Ratings, and 

(2) if either or both of Moody’s or S&P Global Ratings ceases to rate the 2033 Senior Notes or fails to make a rating of the 2033
Senior Notes publicly available for reasons outside of the Company’s control, a Substitute Rating Agency in lieu thereof. 

“Rating Event” means (i) the rating of the 2033 Senior Notes is lowered by both Rating Agencies during the related Trigger
Period and (ii) the 2033 Senior Notes are rated below an Investment Grade rating by both Rating Agencies on any day during such Trigger Period. If either Rating Agency is not providing a rating of the 2033 Senior Notes on any day during such
Trigger Period for any reason, the rating of such Rating Agency shall be deemed to be below Investment Grade on such day and such Rating Agency will be deemed to have lowered its rating of the 2033 Senior Notes during the Trigger Period. For the
avoidance of doubt, the Trustee shall not be charged with knowledge of any Rating Event nor have any duty to monitor the ratings of the Securities. 

“S&P Global Ratings” means S&P Global Ratings, a division of S&P Global Inc.. 

“Substitute Rating Agency” means a “nationally recognized statistical rating organization” as that term is defined in
Section 3(a)(62) of the Exchange Act, selected by the Company (as certified by a resolution of the Board of Directors delivered to the Trustee) as a replacement agency for Moody’s or S&P Global Ratings, or both of them, as the case may
be. 
 “Trigger Period” means the period commencing on the earlier of the first public notice of (a) the occurrence of a
Change of Control or (b) the Company’s intention to effect a Change of Control and ending 60 days following consummation of such Change of Control (which period shall be extended so long as the rating of the 2033 Senior Notes is under
publicly announced consideration for a possible downgrade by either of the Rating Agencies). 
 “Voting Stock” means, with respect
to any Person as of any date, the Capital Stock of such Person that is at the time entitled to vote generally in the election of the board of directors (or other analogous managing body) of such Person.

valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee, either by manual, facsimile or electronic execution, for such Security
or on its behalf pursuant to Section 614, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

consequences of any thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder (it being understood that such 2033 Senior Notes shall not be deemed outstanding for accounting

hereby, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture and this Twenty-Third Supplemental Indenture shall be read, taken and construed as one and the same instrument and all references to Securities in

Twenty-Third Supplemental Indenture limits, qualifies or conflicts with another provision which is required to be included herein or in the Original Indenture by the Trust Indenture Act of 1939, as amended, such required provision shall control.

 Section 6. All covenants and agreements in this Twenty-Third Supplemental Indenture by the Company shall bind

 Section 9. This Twenty-Third Supplemental Indenture may be
simultaneously executed in several counterparts, each of which shall be deemed to be an original, and such counterparts shall together constitute but one and the same instrument. The words “execution,” signed,” “signature,”
and words of like import in this Supplemental Indenture or in any other certificate, agreement or document related to this 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.

instructions (for the purposes of this Section, “Instructions”) given pursuant to the Indenture and delivered using Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency certificate listing
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.
