Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) INTEREST.

Interest (computed on the basis of a 360-day year consisting of twelve 30-day months) shall accrue on the principal amount of this Note from and including January 12, 2024 until maturity at a rate per annum equal to 4.850%.

The Issuer promises to pay interest semi-annually in arrears on January 15 and July 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be July 15, 2024. If an interest payment date or the maturity date falls on a day that is not a Business Day, the related payment of principal or interest will be made on the next succeeding Business Day as if made on the date the payment was due, and no interest shall accrue for the intervening period.

(2) METHOD OF PAYMENT.

The Issuer will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the January 1 or July 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.14 of the Base Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Issuer maintained for such purpose within the City and State of New York, or, at the option of the Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the books and records of the Registrar; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium, if any, on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying Agent. Such payment will be in such money of the United States of America as at the time of payment is legal tender for payment of public and private debts. [The Holder of a Definitive Note is not required to surrender such Definitive Note to the Trustee in order to receive payment of principal at maturity. Such Definitive Note, after payment has been made, shall be cancelled without the requirement of presentation.]³

Exhibit A-7

(3) PAYING AGENT AND REGISTRAR.

Initially, Deutsche Bank Trust Company Americas, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer or any of its Subsidiaries may act in any such capacity.

(4) INDENTURE.

The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and to the Trust Indenture Act for a statement of such terms.

The Issuer’s obligations under the Notes are unconditionally guaranteed on a senior unsecured basis, to the extent set forth in the Indenture, by each of the Guarantors to the extent set forth in the Indenture.

(5) OPTIONAL REDEMPTION.

Prior to December 15, 2028 (the “Par Call Date”), the Issuer 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:

• 100% of the principal amount of the Notes to be redeemed; and

• (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming that such 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 applicable Treasury Rate (as defined below) plus 15 basis points, less (b) unpaid interest accrued to the date of redemption (any excess of the amount described in this bullet point over the amount described in the immediately preceding bullet point, the “Make-Whole Premium”);

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

On or after the Par Call Date, the Issuer may redeem the Notes, in whole or in part, at any time or 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.

Exhibit A-8

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Issuer in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Issuer 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). In determining the Treasury Rate, the Issuer shall select, as applicable: (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 (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 (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 or any successor designation or publication is no longer published, the Issuer 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 such Par Call Date, one with a maturity date preceding such Par Call Date, and one with a maturity date following such Par Call Date, the Issuer 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 Issuer shall select from among these 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.

The Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Exhibit A-9

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.

The Trustee shall have no responsibility for calculating the redemption price for the Notes.

Unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable redemption date. At or before 10:00 a.m. (New York time) on the redemption date, the Issuer will deposit with the Trustee or a paying agent money sufficient to pay the redemption price of and accrued interest on the Notes to be redeemed on such date. If less than all of the Notes are to be redeemed, the Notes to be redeemed shall be selected in accordance with the procedures of DTC.

For the avoidance of doubt, the requirement to pay any Make-Whole Premium shall not arise in connection with any recovery of amounts due as a result of any breach of any covenant contained in the Indenture or the applicable Notes except where the transaction resulting in such breach was consummated with the intent to breach such covenant.

(6) MANDATORY REDEMPTION.

The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

(7) NOTICE OF REDEMPTION.

Notice of redemption will be sent at least 10 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed, except that redemption notices may be sent or mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. In connection with any redemption of Notes, any such notice of redemption may, at the Issuer’s discretion, state that such redemption is subject to one or more conditions precedent, including, but not limited to, completion of an equity offering, other offering, issuance of Indebtedness or other corporate transaction or event. In addition, if such notice of redemption is subject to satisfaction of one or more conditions precedent, such notice may state that, in the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied (or waived by the Issuer in its sole discretion) by the redemption date (whether the original redemption date or the redemption date so delayed).

Exhibit A-10

(8) DENOMINATIONS, TRANSFER, EXCHANGE.

The Notes are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The Issuer need not exchange or register the transfer or exchange of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Issuer need not exchange or register the transfer of any Notes (i) for a period beginning at the opening of business 15 days immediately preceding the sending of notice of redemption of Notes selected for redemption and ending at the close of business on the day such notice is sent or (ii) during the period between a record date and the corresponding Interest Payment Date.

(9) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

(10) AMENDMENT, SUPPLEMENT AND WAIVER. The Indenture, the Notes and the Note Guarantees may be amended, supplemented or waived as provided in Article IX of the Base Indenture.

(11) DEFAULTS AND REMEDIES. If an Event of Default occurs (other than an Event of Default relating to certain events of bankruptcy or insolvency of the Issuer, any of its Significant Subsidiaries or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary) and is continuing, the Trustee or the Holders of at least 30% in aggregate principal amount of the outstanding Notes, in each case, by notice to the Issuer, may declare the principal of, premium, if any, and accrued but unpaid interest, if any, on all the Notes to be due and payable; provided that no such declaration may be made with respect to or as a result of any action taken, and reported publicly or to holders of Notes, more than two years prior to such declaration. If an Event of Default relating to certain events of bankruptcy or insolvency of the Issuer, any of its Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary occurs, the principal of, premium, if any, and interest on all the Notes shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences. The requirement to pay any Make-Whole Premium shall not arise in connection with any recovery of amounts due as a result of any breach of any covenant contained in the Indenture, this Supplemental Indenture or the applicable Notes except where the transaction resulting in such breach was consummated with the intent to breach such covenant.

(12) TRUSTEE DEALINGS WITH ISSUER. The Trustee, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee.

(13) NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, member, manager, partner, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, will have any liability for any obligations of the Issuer or the Guarantors under the Notes, the Indenture, the Note Guarantees 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. The waiver and release are part of the consideration for the issuance of the Notes.
