ARTICLE ONE

DEFINITIONS, CREATION, FORM AND TERMS AND CONDITIONS OF THE DEBT SECURITIES

Section 1.1 Definitions. Capitalized terms used but not otherwise defined in this Eighteenth Supplemental Indenture shall have the meanings ascribed to them in the Fifteenth Supplemental Indenture.

Section 1.2 Additional Notes. As of the date hereof, the Issuer hereby creates and issues the Additional Notes under the Fifteenth Supplemental Indenture and this Eighteenth Supplemental Indenture. The Additional Notes shall be consolidated with, and shall form a single series with, the Initial Notes and shall have the same terms and conditions as the Initial Notes in all respects, except for the issue date, the issue price, the payment of interest accruing prior to the issue date of the Additional Notes and the first Interest Payment Date (as defined below).

Section 1.3 Form of the Notes. The Additional Notes will be issued in the form of one or more permanent fully registered global securities (the “Global Note”) that will be deposited with, or on behalf of the Depository, and registered in the name of the Depository or its nominee, as the case may be, subject to Section 305 of the Base Indenture. So long as the Depository, or its nominee, is the registered owner of the Global Note, the Depository or its nominee, as the case may be, will be considered the sole Holder of the Additional Notes represented by the Global Note for all purposes under the Indenture.

Section 1.4 Terms and Provisions of the Notes. The Additional Notes shall be governed by all of the terms and provisions of the Base Indenture, as supplemented by the Fifteenth Supplemental Indenture and this Eighteenth Supplemental Indenture, and in particular, the following provisions shall be terms of the Additional Notes:

(a) Registration and Form. The Additional Notes shall be issuable in registered form without coupons in minimum denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. Each Additional Note shall be dated the date of its authentication and the Additional Notes shall be substantially in the form of Exhibit A attached hereto.

3

(b) Payment of Principal and Interest. All payments of principal, premiums, if any, and interest in respect of the Global Notes will be made by the Issuer in immediately available funds to the Depository or its nominee, as the case may be, as the Holder of each of the Global Notes. The Additional Notes shall mature, and the unpaid principal thereon, shall be payable, on August 1, 2053, subject to the provisions of the Base Indenture. The rate per annum at which interest shall be payable on the Additional Notes shall be 5.350%. Interest on the Additional Notes will be payable semi-annually in arrears on each February 1 and August 1, commencing August 1, 2024 (each, an “Interest Payment Date”) and on the Stated Maturity as specified in this Section 1.4(b), to the Persons in whose names the Additional Notes are registered in the Security Register applicable to the Additional Notes at the close of business on the fifteenth calendar day (whether or not a Business Day) immediately preceding each Interest Payment Date. Interest on the Additional Notes shall be computed on the basis of a 360-day year of twelve 30-day months. Interest on the Additional Notes shall accrue from February 1, 2024.

(c) Sinking Fund. There shall be no sinking fund provided for the Additional Notes.

(d) Redemption at the Option of the Issuer.

(1) Prior to the Par Call Date, the Issuer shall have the option to redeem the Additional Notes at any time in whole, or from time to time in part, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(x) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Additional 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 (b) interest accrued to the Redemption Date, and

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

plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

(2) On or after the Par Call Date, the Issuer shall have the option to redeem the Additional Notes at any time in whole, or from time to time in part, at a Redemption Price equal to 100% of the principal amount of the Additional Notes to be redeemed plus accrued and unpaid interest thereon to the Redemption Date.

(3) Notwithstanding the foregoing, if the Redemption Date falls after a Record Date and on or prior to the corresponding Interest Payment Date, the Issuer will pay the full amount of accrued and unpaid interest, if any, due on such Interest Payment Date to the Holder of record at the close of business on the corresponding Record Date (instead of the Holder surrendering its Additional Notes for redemption). The Issuer shall not redeem the Additional Notes pursuant to Section 1.4(d)(1) or (2) on any date if the principal amount of the Additional Notes has been accelerated, and such acceleration has not been rescinded or annulled on or prior to such date (except in the case of an acceleration resulting from a default by the Issuer in the payment of the Redemption Price with respect to the Additional Notes to be redeemed).

4

(e) Payment of Notes Called for Redemption by the Issuer.

(1) If notice of redemption has been given at least 10 days but not more than 60 days prior to the Redemption Date to each Holder of Additional Notes to be redeemed as otherwise provided in Article Eleven of the Base Indenture (as amended by the Fifteenth Supplemental Indenture and this Eighteenth Supplemental Indenture), the Additional Notes or portion of Additional Notes with respect to which such notice has been given shall become due and payable on the Redemption Date and at the place or places stated in such notice at the Redemption Price, and unless the Issuer shall default in the payment of such Additional Notes at the Redemption Price, so long as the Paying Agent holds funds irrevocably deposited with it sufficient to pay the Redemption Price of the Additional Notes to be redeemed on the Redemption Date, then (a) such Additional Notes will cease to be Outstanding on and after the date of the deposit, (b) interest on the Additional Notes or portion of Notes so called for redemption shall cease to accrue on and after the Redemption Date, and (c) the Holders of the Additional Notes being redeemed shall have no right in respect of such Additional Notes except the right to receive the Redemption Price thereof. On surrender of such Additional Notes at the place of payment specified in such notice, the said Additional Notes or the specified portions thereof shall be paid and redeemed by the Issuer at the Redemption Price, together with interest accrued thereon to, but excluding, the Redemption Date.

(2) The Notes will not be convertible or exchangeable for any other security or property.

(f) Additional Issues. The Issuer may, from time to time, without the consent of or notice to the Holders of the Additional Notes, create and issue further notes having the same terms and conditions as the Notes in all respects, except for the issue date and, to the extent applicable, the issue price, the payment of interest accruing prior to the issue date and the first Interest Payment Date. Additional notes issued in this manner shall be consolidated with, and shall form a single series with, the previously outstanding Notes; provided, however, that the issuance of such additional notes will not be so consolidated for United States federal income tax purposes unless such issuance constitutes a “qualified reopening” within the meaning of the Internal Revenue Code of 1986, as amended, and the Treasury regulations promulgated thereunder.

Section 1.5 Book-Entry Provisions. This Section 1.5 shall apply only to the Global Notes deposited with or on behalf of the Depository.

(a) The Issuer shall execute and the Trustee shall, in accordance with this Section 1.5 and Section 303 of the Base Indenture, authenticate and deliver the Global Notes that shall be registered in the name of the Depository or its nominee and shall be held by the Trustee as custodian for the Depository.

5

(b) Participants of the Depository shall have no rights either under the Indenture or with respect to the Global Notes. The Depository or its nominee, as applicable, shall be treated by the Issuer, any future Guarantor, the Trustee and any agent of the Issuer, any future Guarantor or the Trustee as the absolute owner and Holder of each such Global Note for all purposes under the Indenture. Notwithstanding the foregoing, nothing herein shall prevent the Issuer, any future Guarantor or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or its nominee, as applicable, or impair, as between the Depository and its participants, the operation of customary practices of such Depository governing the exercise of the rights of an owner of a beneficial interest in the Global Notes.

ARTICLE TWO

ADDITIONAL COVENANTS FOR BENEFIT OF HOLDERS OF NOTES

In addition to the covenants set forth in the Base Indenture, the Issuer hereby further covenants as follows, the following covenants being for the sole benefit of the Holders of the Notes:

Section 2.1 Limitations on Incurrence of Debt.

(a) Aggregate Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such Debt and any other Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Debt and the application of the proceeds from such Debt and such other Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Debt would exceed 65% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate purchase price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger).

(b) Secured Debt Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Secured Debt if, immediately after giving effect to the incurrence of such Secured Debt and any other Secured Debt incurred or repaid since the end of the most recent Reporting Date prior to the incurrence of such Secured Debt and the application of the proceeds from such Secured Debt and such other Secured Debt on a pro forma basis, the aggregate principal amount of the Issuer’s Secured Debt would exceed 50% of the sum of the following (without duplication): (1) the Issuer’s Total Assets as of such Reporting Date; (2) the aggregate purchase price of any assets acquired, and the aggregate amount of proceeds received from any incurrence of other Debt and any securities offering proceeds received (to the extent such proceeds were not used to acquire assets or used to reduce Debt), by the Issuer or any of its Subsidiaries since the end of the most recent Reporting Date prior to the incurrence of such Debt; and (3) the proceeds or assets obtained from the incurrence of such Secured Debt and other securities issued as part of the same transaction on a pro forma basis (including assets to be acquired in exchange for debt assumption and security issuance as in the case of a merger).

6

(c) Debt Service Test. The Issuer will not, and will not permit any of its Subsidiaries to, incur any Debt if, immediately after giving effect to the incurrence of such Debt and the application of the proceeds from such Debt on a pro forma basis, the ratio of Adjusted EBITDA to Interest Expense for the four (4) consecutive fiscal quarters ended on the most recent Reporting Date prior to the incurrence of such Debt would be less than 1.50 to 1.00, and calculated on the following assumptions (without duplication): (1) such Debt and any other Debt incurred since such Reporting Date and outstanding on the date of determination had been incurred, and the application of the proceeds from such Debt (including to repay or retire other Debt) had occurred, on the first day of such four-quarter period; (2) the repayment or retirement of any other Debt since such Reporting Date had occurred on the first day of such four-quarter period; and (3) in the case of any acquisition or disposition by the Issuer or any of its Subsidiaries of any asset or group of assets since such Reporting Date, whether by merger, stock purchase or sale or asset purchase or sale or otherwise, such acquisition or disposition had occurred as of the first day of such four-quarter period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation. If any Debt incurred during the period from such Reporting Date to the date of determination bears interest at a floating rate, then, for purposes of calculating the Interest Expense, the interest rate on such Debt will be computed on a pro forma basis as if the average daily rate during such interim period had been the applicable rate for the entire relevant four-quarter period. For purposes of the foregoing, Debt will be deemed to be incurred by a Person whenever such Person creates, assumes, guarantees or otherwise becomes liable in respect thereof.

(d) Maintenance of Total Unencumbered Assets. As of each Reporting Date, the Issuer’s Unencumbered Assets will not be less than 125% of the Issuer’s Unsecured Debt.

Section 2.2 Guarantee. The payment of principal, interest and all other obligations when due on the Additional Notes is hereby fully and unconditionally guaranteed by the Guarantor on a senior unsecured basis, as set out in Article Sixteen of the Base Indenture.

Section 2.3 Covenant Defeasance and Waiver of Covenant. The covenants set forth in Section 2.1 shall be subject to covenant defeasance under Section 402(3) of the Base Indenture and subject to waiver under Section 1006 thereof.

Section 2.4 Merger, Consolidation or Sale. The Issuer or the Guarantor may consolidate with or into, or sell, assign, convey, transfer or lease all or substantially all of their respective property and assets to, any other entity, provided that:

The Trustee is permitted to engage in other transactions with the Issuer and its Affiliates.
