of the Base Indenture, and the Guarantees thereof by the Guarantors; 
 Sections 901 (9) and 901 (12) of the Base Indenture provide, among
other things, that the Company, the Guarantors and the Trustee may enter into indentures supplemental to the Base Indenture for, among other things, the purposes of (a) establishing the form or terms of Securities of any series as permitted by

SECTION 1.1. Issuance of Notes; Principal Amount; Maturity; Title.  

(1) On August 5, 2021, the Company shall issue and deliver to the Trustee, and the Trustee shall authenticate, the Initial Notes
substantially in the form set forth in Section 3.2 below, in each case with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by the Base Indenture and this Seventeenth Supplemental
Indenture, and with such letters, numbers, or other marks of identification and such legends or endorsements placed thereon as may be required to comply with applicable tax laws or the rules of any securities exchange or Depositary therefor or as
may, consistently herewith, be determined by the Officer executing such Notes, as evidenced by the execution of such Notes. 
 (2) The
Initial Notes to be issued pursuant to the Indenture shall be issued in the aggregate principal amount of $650,000,000 and shall mature on August 5, 2028 (the “Stated Maturity”), unless the Notes are redeemed prior to that date as
described in Section 5.1. The aggregate principal amount of Initial Notes Outstanding at any time may not exceed $650,000,000, except for Notes issued, authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu
of, other Notes of the series pursuant to Sections 304, 305, 306, 906 or 1107 of the Base Indenture and except for any Notes which, pursuant to Section 303 of the Base Indenture, are deemed never to have been authenticated and delivered. The
Company may without the consent of the Holders, issue additional Notes as part of the same series and on the same terms and conditions (and having the same Guarantors) and with the same CUSIP numbers and ISIN numbers as the Initial Notes
(“Additional Notes”), but such Additional Notes may be offered at a different offering price or have a different issue date, initial interest accrual or initial interest payment date; provided that if any Additional Notes are
issued at a price that causes such Additional Notes to have “original issue discount” within the meaning of Section 1273 of the United States Internal Revenue Code of 1986, as amended, and regulations of the United States Department
of Treasury thereunder, such Additional Notes shall not have the same CUSIP number or ISIN number as the Initial Notes. 
 (3) The Notes
shall be issued only in fully registered form without coupons in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. 

(4) Pursuant to the terms hereof and Sections 201 and 301 of the Base Indenture, the Company hereby creates a series of Securities designated
as the “1.625% Senior Notes due 2028” of the Company (as amended or supplemented from time to time, that are issued under the Indenture, including both the Initial Notes and the Additional Notes, if any, the “Notes”),
which Notes shall be deemed “Securities” for all purposes under the Base Indenture. 
 SECTION 1.2. Interest.  

(1) Interest on a Note will accrue at the per annum rate of 1.625% (the “Note Interest Rate”), from and including the date
specified on the face of such Note to, but excluding, the date on which the principal thereof is paid, deemed paid, or made available for payment and, in each case, will be paid on the basis of a 360-day year
comprised of twelve 30-day months.

 (2) The Company shall pay interest on the Notes semi-annually in arrears on February 5
and August 5 of each year (each, an “Interest Payment Date”), commencing February 5, 2022. 
 (3) Interest shall
be paid on each Interest Payment Date to the registered Holders of the Notes at the close of business on the Regular Record Date. 
 (4)
Amounts due on the Stated Maturity or earlier Redemption Date of the Notes will be payable at the Corporate Trust Office. The Company shall make payments of principal, premium, if any, and interest or the Repurchase Price in connection with a Change
of Control Repurchase Event in respect of the Notes in book-entry form to DTC in immediately available funds, while disbursement of such payments to owners of beneficial interests in Notes in book-entry form will be made in accordance with the
procedures of DTC and its participants in effect from time to time. The Company may at any time designate additional Paying Agents or rescind the designation of any Paying Agent or approve a change in the office through which any Paying Agent acts,
except that the Company shall be required to maintain a Paying Agent in each Place of Payment for the Notes. Neither the Company nor the Trustee shall impose any service charge for any transfer or exchange of a Note. However, the Company may require
Holders of the Notes to pay any taxes or other governmental charges in connection with a transfer or exchange of Notes. 
 (5) If any
Interest Payment Date, Stated Maturity, or earlier Redemption Date or Repurchase Price Payment Date falls on a day that is not a Business Day in The City of New York, the Company shall make the required payment of principal, premium, if any, and/or
interest or Repurchase Price in connection with a Change of Control Repurchase Event on the next succeeding Business Day as if it were made on the date payment was due, and no interest will accrue on the amount so payable for the period from and
after that Interest Payment Date, Stated Maturity or earlier Redemption Date or Repurchase Price Payment Date, as the case may be, to such next succeeding Business Day. 

SECTION 1.3. Relationship with Base Indenture.  

The terms and provisions contained in the Base Indenture will constitute, and are hereby expressly made, a part of this Seventeenth
Supplemental Indenture. However, to the extent any provision of the Base Indenture conflicts with the express provisions of this Seventeenth Supplemental Indenture, the provisions of this Seventeenth Supplemental Indenture will govern and be

 [FORM OF REVERSE OF NOTE] 

Indenture. This Note is one of a duly authorized issue of securities of the Company designated as its “1.625% Senior Notes due
2028” (herein called the “Notes”), issued under a Seventeenth Supplemental Indenture, dated as of August 5, 2021 (the “Seventeenth Supplemental Indenture”), to an indenture, dated as of August 20,
2009 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the “Base Indenture” and herein with the Seventeenth Supplemental Indenture, collectively, the “Indenture”), among
the Company, the Guarantors and The Bank of New York Mellon, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. The aggregate
principal amount of Initial Notes Outstanding at any time may not exceed $650,000,000 in aggregate principal amount, except for, or in lieu of, other Notes of the series pursuant to Sections 304, 305, 306, 906 or 1107 of the Base Indenture and
except for any Notes which, pursuant to Section 303 of the Base Indenture, are deemed never to have been authenticated and delivered. The Seventeenth Supplemental Indenture pursuant to which this Note is issued provides that Additional Notes
may be issued thereunder. 
 All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the
Indenture. In the event of a conflict or inconsistency between this Note and the Indenture, the provisions of the Indenture shall govern. 

Optional Redemption. Prior to June 5, 2028, the Company may, at its option, redeem all or a part of the Notes upon not more than
60 nor less than 15 days prior notice, at a redemption price in cash equal to the greater of (i) 100% of the principal amount of any Notes being redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal
and interest on the Notes to be redeemed (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 10 basis points, plus in each case accrued and unpaid interest thereon to, but excluding, the Redemption Date. 

On or after June 5, 2028, the Company may, at its option, redeem all or a part of the Notes upon not more than 60 nor less than 15 days
prior notice, at a redemption price in cash equal to 100% of the principal amount of any Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date. 

Any notice of any redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited
to, completion of a securities offering or other corporate transaction. 
 Change of Control Repurchase Event. In the event of a
Change of Control Repurchase Event, unless the Company has exercised its option to redeem the Notes, the Company will make an offer to each Holder of Notes to repurchase all or any part of that Holder’s Notes at a repurchase price in cash equal
to 101% of the aggregate principal amount of the Notes, plus any accrued and unpaid interest, if any, pursuant to the provisions of Section 6.2 of the Seventeenth Supplemental Indenture. 

  
 17 













 Global Security. If this Note is a Global Security, then, in the event of a deposit
or withdrawal of an interest in this Note, including an exchange, transfer, redemption, repurchase or conversion of this Note in part only, the Trustee, as custodian of the Depositary, shall make an adjustment on its records to reflect such deposit
or withdrawal in accordance with the Applicable Procedures. 
 Defaults and Remedies. If an Event of Default shall occur and be
continuing, the principal of all the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. Upon payment of the amount of principal so declared due and payable, all obligations of the Company in respect of
the payment of the principal of and interest on the Notes shall terminate. 
 No Holder of Notes shall have any right to institute any
proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver, assignee, trustee, liquidator or sequestrator (or similar official) or for any other remedy hereunder (except actions for payment of overdue
principal of, and premium, if any, or interest on such Notes in accordance with its terms), unless (i) such Holder has previously given written notice to the Trustee of a continuing Event of Default, specifying an Event of Default, as required
under the Indenture; (ii) the Holders of not less than 25% in aggregate principal amount of the Outstanding Notes shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as
Trustee under the Indenture; (iii) such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request; (iv) the Trustee has
failed to institute any such proceeding for 60 days after its receipt of such notice, request and offer of indemnity; and (v) 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 aggregate principal amount of the Outstanding Notes, it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by
virtue of, or by availing of, any provision of the Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right
under the Indenture, except in the manner provided in the Indenture and for the equal and ratable benefit of all of such Holders. 
 The
foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal of, and premium, if any, or interest hereon, on or after the respective due dates expressed herein. 

Amendment, Supplement and Waiver. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the Holders of the Notes under the Indenture at any time by the Company and the Trustee with the written consent of the Holders of at least a majority in aggregate principal
amount of the Outstanding Notes. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Outstanding Notes, on behalf of the Holders of all the Notes, to waive compliance by the


  
 18 













 
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
or such other Note. Certain modifications or amendments to the Indenture require the consent of the Holder of each Outstanding Note affected. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair (without the consent of the
Holder hereof) the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed. 

Registration and Transfer. As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note
is registerable on the Security Register. Upon surrender for registration of transfer of this Note at the office or agency of the Company in a Place of Payment, the Company shall execute, and the Trustee shall authenticate and deliver, in the name
of the designated transferee or transferees, one or more new Notes of any authorized denominations and of like tenor and principal amount. As provided in the Indenture and subject to certain limitations therein set forth, at the option of the
Holder, this Note may be exchanged for one or more new Notes of any authorized denominations and of like tenor and principal amount, upon surrender of this Note at such office or agency. Upon such surrender by the Holder, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of like tenor and principal amount. Every Note presented or surrendered for
registration of transfer or for exchange shall be duly endorsed (if so required by the Company or the Trustee), or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the
Holder thereof or such Holder’s attorney duly authorized in writing. 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 that may be imposed in connection therewith. 
 Prior to due presentment of this Note for registration of transfer, the
Company, the Guarantors, the Trustee and any agent of the Company, a Guarantor or the Trustee may treat the Person in whose name such Note is registered as the owner thereof for all purposes, whether or not such Note be overdue, and neither the
Company, the Guarantors, the Trustee nor any agent of the Company, a Guarantor or the Trustee shall be affected by notice to the contrary. 

Guarantee. As expressly set forth in the Base Indenture, payment of this Note is jointly and severally and fully and unconditionally
guaranteed by the Guarantors that have become and continue to be Guarantors pursuant to the Indenture. Guarantors may be released from their obligations under the Indenture and their Guarantees under the circumstances specified in the Base
Indenture.

“tif” or “jpg”) and other electronic signatures (including, without limitation, DocuSign and AdobeSign), so long as any electronic signature is a true representation of such signatory’s actual signature. 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.

Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Seventeenth Supplemental Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

 The
Credit Parties shall not, and shall not cause or permit any of their respective Subsidiaries to, create, assume, incur or guarantee any indebtedness for money borrowed that is secured by a pledge, mortgage, lien or other encumbrance (other than

merger, consolidation, sale of assets or otherwise) to all or any substantial part of the business of any of such Subsidiaries, without providing that the Notes (together with, if the Credit Parties shall so determine, any other indebtedness of, or
guarantee by, the Credit Parties ranking equally with the Notes and existing as of the closing of the offering of the Notes or thereafter created) will be secured equally and ratably with or prior to all other indebtedness secured by such pledge,
mortgage, lien or other encumbrance on the voting stock or profit participating equity interests of any such entities for so long as such other indebtedness is so secured. This Section 6.1 shall not limit the ability of the Credit Parties or

 22 













 SECTION 6.2. Obligation to Offer to Repurchase Upon a Change of Control Repurchase
Event.  
 (1) If a Change of Control Repurchase Event occurs, unless the Company has exercised its option to redeem the Notes
pursuant to Article V, the Company shall make an offer to each Holder of Notes to repurchase all or any part of that Holder’s Notes (the “Change of Control Offer”) at a repurchase price in cash equal to 101% of the aggregate
principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to, but excluding, the date of purchase (the “Repurchase Price”). 

(2) In connection with any Change of Control related to a Change of Control Repurchase Event and any particular reduction in the rating on the
Notes, the Company shall request from the Rating Agencies each such Rating Agency’s written confirmation that such reduction in the rating on the Notes was the result, in whole or in part, of any event or circumstance comprised of or arising as
a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of any Below Investment Grade Rating Event). The Company shall promptly deliver an officers’
certificate to the Trustee certifying as to whether or not such confirmation has been received or denied. 
 (3) Within 30 days following any
Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Company shall give notice to each Holder of Notes, with a written copy to the
Trustee. Such notice shall state: 
 (i) a description of the transaction or transactions that constitute or may constitute
the Change of Control Repurchase Event; 
 (ii) that the Change of Control Offer is being made pursuant to this
Section 6.2; 
 (iii) the Repurchase Price and the date on which the Repurchase Price will be paid, which date shall be
a Business Day that is no earlier than 30 days and no later than 60 days from the date such notice is mailed, other than as may be required by law (the “Repurchase Price Payment Date”); and 

(iv) if the notice is given prior to the date of consummation of the Change of Control, a statement that the offer to purchase
is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. 
 (4) The
Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection
with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Company
shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict. 

  
 23 













 (5) On the Repurchase Price Payment Date, the Company shall, to the extent lawful: 

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer on the
Repurchase Price Payment Date; 
 (ii) deposit with the Paying Agent an amount equal to the Repurchase Price in respect of
all Notes or portions of Notes properly tendered; and 
 (iii) deliver or cause to be delivered to the Trustee the Notes
properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased. 
 The
Paying Agent shall promptly deliver to each Holder of Notes properly tendered the Repurchase Price for such Notes, and the Trustee shall promptly authenticate (if applicable) and deliver (or cause to be transferred by book-entry) to each Holder of
Notes properly tendered a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note will be in a principal amount of $2,000 or any integral multiple of $1,000 in excess thereof. 

(6) Notwithstanding the foregoing, the Company shall not be required to make an offer to repurchase the Notes upon a Change of Control
Repurchase Event if (i) a third party makes such an offer in respect of the Notes in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all the Notes
properly tendered and not withdrawn under its offer or (ii) the Company has given written notice of a redemption as provided under Section 1104 of the Base Indenture; provided that the Company has not failed to pay the Redemption
Price on the Redemption Date. 
 SECTION 6.3. Financial Reports  

Section 704 of the Base Indenture shall apply to the reports, information, and documents delivered under this Section 6.3. 

(1) For so long as the Corporation is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, the Company shall
provide (or cause its Affiliates to provide) to the Trustee, unless available on the Commission’s Electronic Data Gathering, Analysis and Retrieval System (or successor system), within 15 days after the Corporation files the same with the
Commission, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) which the Corporation may
file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act. The Trustee may conclusively presume, and shall incur no liability in such presumption, that the Corporation has not filed any such reports, information,
documents and other reports with the Commission that are not available on the Commission’s Electronic Data Gathering, Analysis and Retrieval System (or successor system) unless and until it shall have received written notice from the Company to
the contrary. 

  
 24 













 (2) For so long as any of the Notes remain Outstanding, the Company shall, or shall cause
its Affiliates to, furnish to the Holders of the Notes and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act and, unless available on the Commission’s
Electronic Data Gathering, Analysis and Retrieval System (or successor system), such information for the Corporation (as if such rule applied to it); provided, however, that if any time the Corporation no longer directly or indirectly
controls the Credit Parties or guarantees the Notes, such information shall be provided for either (i) the Credit Parties on a combined and consolidated basis and taken as a whole or (ii) any Person that directly or indirectly controls the
Credit Parties and guarantees the Notes (in each case, as if such rule applied to such Person). The Company shall, or shall cause its Affiliates to, make the above information and reports available to securities analysts and prospective investors
upon request.

memorandum dated July 29, 2021, to the extent that such provision in the Description of the Notes was intended to be a verbatim recitation of a provision of this Seventeenth Supplemental Indenture, the Base Indenture or the Notes, shall be

Notes. 
 Section 902 of the Base Indenture shall not apply to the Notes, and, with respect to the Notes, any reference to

Covenant Defeasance.  
 Section 1303 of the Base Indenture shall not apply to the Notes, and, with respect to the Notes,

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
