#### ITEM 1.01 - ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT
On January 11, 2023, Crown Castle Inc. ("Company") closed its previously announced public offering ("Debt Offering") of $1,000,000,000 aggregate principal amount of the Company's 5.000% Senior Notes due 2028 ("Notes"). The Notes were issued pursuant to an indenture dated as of February 11, 2019 ("Base Indenture"), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee ("Trustee"), as amended and supplemented by the eighth supplemental indenture dated as of January 11, 2023 ("Eighth Supplemental Indenture" and, together with the Base Indenture, "Indenture"), between the Company and the Trustee. The Company intends to use the net proceeds from the Debt Offering to repay outstanding indebtedness under its existing revolving credit facility and pay related fees and expenses.

The Notes are senior unsecured obligations of the Company, which rank equally with all existing and future senior indebtedness of the Company, including the Company's obligations under its senior unsecured credit facility, its commercial paper program and its existing bonds, and senior to all future subordinated indebtedness of the Company. The Notes will effectively rank junior to all of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness. The Notes will be structurally subordinated to all existing and future liabilities and obligations of the Company's subsidiaries. The Notes will bear interest at a rate of 5.000% per annum, with interest on the Notes payable semi-annually on January 11 and July 11, to persons who are registered holders of the Notes on the immediately preceding December 28 and June 27, beginning on July 11, 2023.

The Indenture limits the ability of the Company and its subsidiaries to incur certain liens and merge with or into other companies, in each case subject to certain exceptions and qualifications set forth in the Indenture.

In the event of a Change of Control Triggering Event (as defined in the Indenture), holders of the Notes will have the right to require the Company to repurchase all or any part of the Notes at a purchase price equal to 101% of the aggregate principal amount of such Notes, plus accrued and unpaid interest, if any, to the date of such repurchase.

The Notes will mature on January 11, 2028. However, the Company, at its option, may redeem some or all of the Notes at any time or from time to time prior to their maturity. If the Company elects to redeem the Notes prior to December 11, 2027 (the date that is one month prior to their maturity date) ("Par Call Date"), the Company will pay a redemption price in respect of the Notes to be redeemed equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed discounted to the redemption date (assuming the 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 (as defined in the Eighth Supplemental Indenture) plus 25 basis points less (b) interest accrued on those Notes to the date of redemption, and

(2) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the redemption date.

If the Company elects to redeem the Notes on or after the Par Call Date, the Company will pay a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

The above description of the Indenture does not purport to be a complete statement of the parties' rights and obligations under the Indenture and is qualified in its entirety by reference to the terms of the Base Indenture, a copy of which was filed as Exhibit 4.1 to the Company's Current Report on Form 8-K filed on February 11, 2019, and the Eighth Supplemental Indenture, a copy of which the Company is filing as Exhibit 4.1 to this Current Report on Form 8-K, and which is incorporated herein by reference.

EIGHTH SUPPLEMENTAL INDENTURE (this "**Supplemental Indenture**") dated as of January 11, 2023, to the Indenture dated as of February 11, 2019 (the "**Base Indenture**," and, together with this Supplemental Indenture, the "**Indenture**") between Crown Castle Inc. (formerly known as Crown Castle International Corp.), a Delaware corporation (the "**Company**"), and The Bank of New York Mellon Trust Company, N.A., as Trustee.

WHEREAS, the Company has executed and delivered to the Trustee the Base Indenture providing for the issuance from time to time of one or more Series of Securities;

WHEREAS, Section 9.01 of the Base Indenture provides for the Company and the Trustee to enter into an indenture supplemental to the Base Indenture without the consent of any Holders (as defined in the Base Indenture) to establish the form or terms of Securities of a Series as permitted by Section 2.02 and Section 2.03 of the Base Indenture;

WHEREAS, pursuant to Section 2.02 of the Base Indenture, the Company wishes to provide for the issuance of a Series of Securities, the 5.000% Senior Notes due 2028 (the "**Notes**"), the form and terms of such Notes and the terms, provisions and conditions thereof to be set forth as provided in this Supplemental Indenture; and

WHEREAS, the Company has requested that the Trustee execute and deliver this Supplemental Indenture, and all requirements necessary to make this Supplemental Indenture a valid, binding and enforceable instrument in accordance with its terms, and to make the Notes, when executed by the Company and authenticated and delivered by the Trustee, the valid, binding and enforceable obligations of the Company, have been done and performed, and the execution and delivery of this Supplemental Indenture has been duly authorized in all respects;

NOW, THEREFORE, in consideration of the covenants and agreements set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1.1. <u>Application of this Supplemental Indenture.</u> Notwithstanding any other provision of this Supplemental Indenture, the provisions of this Supplemental Indenture and any amendments or modifications to the terms of the Base Indenture made herein are expressly and solely for the benefit of the Holders (and not for the benefit of any other Series of Securities (as defined in the Base Indenture)). The Notes constitute a Series of Securities as provided in Section 2.01 of the Base Indenture. Unless otherwise expressly specified, references in this Supplemental Indenture to specific Article numbers or Section numbers refer to Articles and Sections contained in this Supplemental Indenture, and not the Base Indenture or any other document. To the extent that the provisions (including the definitions set forth in Sections 1.3 and 1.4) of this Supplemental Indenture conflict with any provision of the Base Indenture, the provisions of this Supplemental Indenture shall govern and be controlling, with respect to the Notes (and only with respect to the Notes).

Beneficial Owner, directly or indirectly, of more than 50% of the voting power of the Voting Stock of the Company; provided that a transaction in which the Company becomes a Subsidiary of another Person shall not constitute a Change of Control if
(a) the Company's stockholders immediately prior to such transaction Beneficially Own, directly or indirectly through one or more intermediaries, 50% or more of the voting power of the outstanding Voting Stock of such other Person of whom
the Company is a Subsidiary immediately following such transaction and (b) immediately following such transaction, no person (as defined in this clause (2)) other than such other Person, Beneficially Owns, directly or indirectly, more than 50%
of the voting power of the Voting Stock of the Company; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) the first day on which a majority of the members of the Board of Directors are not Continuing Directors.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the Net Income (but not loss) of any Person other than the Company that is not a Subsidiary or that is
accounted for by the equity method of accounting shall be included only to the extent of the amount of dividends or distributions paid in cash to the referent Person or a Subsidiary thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) the Net Income of any Person acquired in a pooling of interests transaction for any period prior to the date of

currency exchange rates.

"**Holder**" means a Person in whose name a Note is registered on the Registrar's books.

"**S&P**" means S&P Global Ratings, a division of S&P Global Inc., or any successor to the rating agency business thereof.

"**Supplemental Indenture**" means this Supplemental Indenture, as amended or supplemented from time to time.

"**Treasury Rate**" means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

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) ("**H.15 TCM**"). In determining the Treasury Rate, the Company shall select, as applicable:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

If on the third Business Day preceding the redemption date H.15 TCM 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 United States Treasury security maturing

------

on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States 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 United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among those two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States 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 United States 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 United States Treasury security, and rounded to three decimal places.

"**Unrestricted Subsidiary**" means (1) (a) each of Crown Castle Investment Corp. and Crown Castle Investment II Corp. and (b) any Newly Created Subsidiary of the Company that is designated by the Board of Directors as an Unrestricted Subsidiary, in each case until such time as the Board of Directors may designate Crown Castle Investment Corp., Crown Castle Investment II Corp. or such Newly Created Subsidiary, as applicable, to be a Subsidiary; *provided* that no Default or Event of Default would occur or be existing following such designation, and (2) any subsidiary of an Unrestricted Subsidiary. Any such designation by the Board of Directors shall be evidenced to the Trustee by filing with the Trustee a certified copy of the board resolution giving effect to such designation. At the time of designation of an Unrestricted Subsidiary as a Subsidiary, such Subsidiary shall be deemed to incur outstanding Indebtedness and grant any existing Liens.

"**Voting Stock**" of any Person as of any date means the Capital Stock of such Person that is normally entitled to vote in the election of the board of directors, managers or trustees of such Person.

Any Note so accepted for payment shall cease to accrue interest on and after the Change of Control Payment Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Change of Control provisions described in this Section 4.2 shall be applicable whether or not any other provisions of the Indenture are applicable.

If the provisions of any of the applicable securities laws or securities regulations conflict with the provisions of this Section 4.2, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.2 by virtue of the compliance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Company shall not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer. In addition, notwithstanding the occurrence of a Change of Control Triggering Event, the Company shall not be obligated to make a Change of Control Offer in the event it has delivered a notice of redemption (which is or has become unconditional) with respect to all of the outstanding Notes as provided under Section 3.1. A Change of Control Offer may be made in advance of a Change of Control Triggering Event and conditioned upon such Change of Control Triggering Event if a definitive agreement is in place for the Change of Control Triggering Event at the time of making the Change of Control Offer. The provisions under the Indenture relating to the Company's obligation to make an offer to repurchase the Notes as a result of a Change of Control Triggering Event may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes then outstanding.

CROWN CASTLE INC. (formerly known as Crown Castle International Corp.), a corporation duly organized and existing under the laws of the State of Delaware (herein called the "**Company**," which term includes any successor Person under the Indenture hereinafter defined), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal sum of $(Dollars)[(as such sum may be increased or decreased as set forth on the

Schedule of Exchanges of Notes attached hereto)]<sup>2</sup> on January 11, 2028, and to pay interest thereon from January 11, 2023 or from the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, semi-annually on January 11 and July 11 (each, an "**Interest Payment Date**") in each year, commencing July 11, 2023, at the rate of 5.000% per annum, until the principal hereof is paid or made available for payment.

The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Note is registered at the close of business on the regular record date for such interest, which shall be December 28 or June 27, as the case may be, next preceding such Interest Payment Date or, if such record date is not a Business Day, at the close of business of the immediately succeeding Business Day. A "**Business Day**" shall mean any day other than a Saturday, Sunday or a day on which banking institutions in the City of New York or at a place of payment are authorized by law, regulation or executive order to remain closed. If a payment date is not a Business Day at a place of payment, payment may be made at that place on the next succeeding day that is a Business Day, and no interest shall accrue on such payment for the intervening period. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such regular record date and shall be paid to the Person in whose name this Note is registered at the close of business on a subsequent special record date, which date shall be the fifteenth day next preceding the date fixed by the Company for the payment of defaulted interest or the next succeeding Business Day if such date is not a Business Day. At least 30 days before the special record date, the Company shall send or cause to be sent to each Holder, with a copy to the Trustee, a notice that states the special record date, the payment date and the amount of defaulted interest and the amount of interest payable on such defaulted interest, if any, to be paid.

If a Holder has given wire transfer instructions to the Company, the Company will make all payments of principal, premium and interest, if any, on that Holder's Notes in accordance with those instructions. All other payments on the Notes will be made at the office or agency of the Paying Agent and Registrar for the Notes within the City and State of New York unless, with respect to such other payments, the Company elects to make interest payments by check sent to the Holders at their address set forth in the register of Holders. Interest will be computed on the basis of a 360-day year composed of twelve 30-day months.

Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof or an authenticating agent appointed by the Company, by manual, facsimile or electronic signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

**[FORM OF REVERSE OF 5.000% NOTE]** 

1. Notes.

This Note is one of a duly authorized issue of senior notes of the Company, issued and to be issued in one or more Series under the Eighth Supplemental Indenture, dated as of January 11, 2023 (the "**Supplemental Indenture**"), to the Indenture dated as of February 11, 2019 (the "**Base Indenture**" and, together with the Supplemental Indenture, the "**Indenture**") 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 and of the terms upon which the Notes (as defined below) are, and are to be, authenticated and delivered. To the extent the provisions of this Note are inconsistent with the provisions of the Indenture, the Indenture shall control. This Note is one of the Series designated on the face hereof as "5.000% Senior Notes due 2028" (herein called the "**Notes**"), issued in an initial aggregate principal amount of $1,000,000,000. The Notes constitute a Series of Securities under the Indenture. All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

2. No Sinking Fund.

No sinking fund is provided for the Notes.

3. Optional Redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Prior to the Par Call Date, the Company may redeem the 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) (i) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed discounted to the redemption date (assuming the 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 (ii) interest accrued on those Notes to the date of redemption, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to the redemption date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) On and after the Par Call Date, the Company may redeem the 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 Notes being redeemed plus accrued and unpaid interest thereon to the redemption date.

4. Selection and Notice of Redemption.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary's procedures) at least 10 days but not more than 60 days before the redemption date to each Holder of Notes to be redeemed. Notices of

------

redemption may be conditional and, at the Company's discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. For so long as the Notes are held by DTC (or another Depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the Depositary.

5. Repurchase at Option of Holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) If a Change of Control Triggering Event occurs with respect to the Notes, each Holder of Notes shall have the right to require the Company to repurchase all or any part, equal to $2,000 or an integral multiple of $1,000 thereafter, of such Holder's Notes pursuant to the offer described below (the "**Change of Control Offer**"). The offer price in any Change of Control Offer shall be payable in cash and will be 101% of the aggregate principal amount of any Notes repurchased plus accrued and unpaid interest on such Notes, if any (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), to the date of purchase (the "**Change of Control Payment**"). Within 30 days following any Change of Control Triggering Event and subject to certain limitations described below, the Company shall send a notice to each Holder describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Notes on the date specified in the notice (the "**Change of Control Payment Date**"). The Change of Control Payment Date shall be no earlier than 30 days and no later than 60 days from the date the notice is sent, pursuant to the procedures required by the Indenture and described in such notice.

6. Acceleration Upon Event of Default.

The Events of Default relating to the Notes are set forth in Section 6.01 of the Indenture. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then-outstanding Notes may declare all such Notes to be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default with respect to the Notes arising from Section 6.01(a)(vii) or Section 6.01(a)(viii) of the Indenture, with respect to the Company, all outstanding Notes shall become due and payable without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power.

The Holders of a majority in aggregate principal amount of the then-outstanding Notes by notice to the Trustee may, on behalf of the Holders of all Notes, waive any existing Default or Event of Default and its consequences under the Indenture, except a continuing Default or Event of Default in the payment of the principal of, premium, if any, and interest on the Notes (including in connection with a Change of Control Offer) (*provided*, *however*, that the Holders of a majority in aggregate principal amount of the then-outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). 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 the Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

7. Amendment and Modification.

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 with respect to the Notes under the Indenture at any time by the Company and the Trustee with the consent of the Holders of at least a majority in principal amount of the Notes then-outstanding, voting as a single class. The Indenture also contains provisions permitting the Holders of at least a majority in principal amount of the Notes then-outstanding, on behalf of the Holders of all the 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 Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued 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.

8. Transfer and Exchange.

As provided in the Indenture and subject to certain limitations set forth therein, the Notes shall be transferable only upon the surrender of a Note for registration of transfer. When a Note is presented to the Registrar with a request to register a transfer, the Registrar will register the transfer as requested if the requirements of the Indenture are satisfied. When Notes are presented to the Registrar with a request to exchange them for an equal principal amount of Notes of other denominations, the Registrar shall make the exchange as requested if the requirements of the Indenture are met. To permit registration of transfers and exchanges, the Company will execute and the Trustee will authenticate Notes at the Registrar's request.

9. No Service Charge.

No service charge shall be made for any such registration of transfer or exchange, but the Company or the Registrar may require payment by the Holder of a sum sufficient to pay all taxes, assessments or other governmental charges in connection therewith.

10. Treatment as Owner.

Prior to the due presentation of this Note for registration of transfer, the Company, the Trustee, the Paying Agent or the Registrar may deem and treat the Person in whose name this Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and (subject to the provisions with respect to record dates) interest on such Note and for all other purposes whatsoever, whether or not such Note is overdue, and none of the Company, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

11. No Liability.

No past, present or future director, officer, employee, incorporator or stockholder of the Company, as such, shall have any liability for any obligations of the Company under the Notes

------

or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Notes.

12. Governing Law.

THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THE INDENTURE AND THE NOTES.

The Notes will be issued under the indenture dated as of February 11, 2019 (the "Base Indenture"), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the "Trustee"), as supplemented by the Eighth Supplemental Indenture dated as of January 11, 2023 (together with the Base Indenture, the "Indenture"), between the Company and the Trustee, in accordance with the Underwriting Agreement, dated January 9, 2023 (the "Underwriting Agreement"), among BNP Paribas Securities Corp., J.P. Morgan Securities LLC, MUFG Securities Americas Inc., PNC Capital Markets LLC, RBC Capital Markets, LLC and Truist Securities, Inc., as Representatives of the several Underwriters listed on Schedule I thereto (the "Underwriters"), and the Company.
