WHEREAS, pursuant to Section 901 of the Indenture, the parties hereto are authorized to execute and deliver this Supplemental Indenture to amend the Indenture, without the consent of any Holder;

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Issuer, the Company, the Subsidiary Guarantors and the Trustee mutually covenant and agree for the benefit of the Holders of the Notes as follows:

1. Defined Terms. As used in this Supplemental Indenture, terms defined in the Indenture or in the preamble or recital hereto are used herein as so defined. The words “herein,” “hereof” and “hereby” and other words of similar import used in this Supplemental Indenture refer to this Supplemental Indenture as a whole and not to any particular section hereof.

2. Title of Notes. There shall be a series of Notes of the Issuer designated the “5.125% Senior Notes due 2027” (the “November 2019 Notes”).

3. Maturity Date. The final Stated Maturity of the November 2019 Notes shall be December 1, 2027.

4. Interest and Interest Rates. Interest on the Outstanding principal amount of November 2019 Notes will accrue at the rate of 5.125% per annum and will be payable semi- annually in arrears on June 1 and December 1 in each year, commencing on June 1, 2020, to holders of record on the immediately preceding May 15 and November 15, respectively (each such May 15 and November 15, a “Regular Record Date”). Interest on the November 2019 Notes will accrue from the most recent date to which interest has been paid or provided for or, if no interest has been paid, from November 22, 2019, except that interest on any Additional November 2019 Notes (as defined below) issued on or after the first Interest Payment Date will

accrue (or will be deemed to have accrued) from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid on such Additional November 2019 Notes, from the Interest Payment Date immediately preceding the date of issuance of such Additional November 2019 Notes (or if the date of issuance of such Additional November 2019 Notes is an Interest Payment Date, from such date of issuance); provided that if any November 2019 Note issued in exchange therefor are surrendered for exchange on or after a record date for an Interest Payment Date that will occur on or after the date of such exchange, interest on such Note received in exchange thereof will accrue from such Interest Payment Date.

Subject to Section 407 of the Indenture, the Issuer may from time to time, without the consent of the Holders, create and issue Additional Notes having the same terms and conditions as the November 2019 Notes in all respects or in all respects except for issue date, issue price and, if applicable, the first date on which interest accrues and the first payment of interest thereon. Additional Notes issued in this manner will be consolidated with, and will form a single series with, the November 2019 Notes (any such Additional Notes, “Additional November 2019 Notes”), unless otherwise specified for Additional Notes in an applicable Notes Supplemental Indenture, or otherwise designated by the Issuer, as contemplated by Section 301 of the Indenture.

6. Redemption. (a) The November 2019 Notes will be redeemable, at the Issuer’s option, in whole or in part, at any time and from time to time on and after December 1, 2022 and prior to maturity at the applicable redemption price set forth below. The November 2019 Notes will be so redeemable at the following redemption prices (expressed as a percentage of principal amount), plus accrued and unpaid interest, if any, to, but excluding, the relevant Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the Redemption Date pursuant to Section 307 of the Indenture), if redeemed during the 12-month period commencing on December 1, 2022 of the years set forth below:

(b) In addition, at any time and from time to time prior to December 1, 2022, the Issuer at its option may redeem November 2019 Notes in an aggregate principal amount equal to up to 40.0% of the original aggregate principal amount of the Notes (including the principal amount of any Additional November 2019 Notes, or any other Additional Notes of the same series as the November 2019 Notes), with funds in an equal aggregate amount (the “Redemption Amount”) not exceeding the aggregate proceeds of one or more Equity Offerings, at a redemption price (expressed as a percentage of principal amount thereof) of 105.125%, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the Redemption Date pursuant to Section 307 of the Indenture); provided, however, that an aggregate principal amount of November 2019 Notes equal to at least 50.0% of the original aggregate principal amount of November 2019 Notes

3

(including the principal amount of any Additional November 2019 Notes, or any other Additional Notes of the same series as the November 2019 Notes) must remain outstanding immediately after each such redemption, unless all such November 2019 Notes are redeemed substantially concurrently. Any amount payable pursuant to this Section 6(b) may be funded from any source (including amounts in excess of the Redemption Amount). Any notice of any such redemption may be given prior to the completion of the related Equity Offering, but in no event may be given more than 180 days after the completion of the related Equity Offering.

(c) At any time prior to December 1, 2022, the November 2019 Notes may also be redeemed in whole or in part, at the Issuer’s option, at a price (the “Redemption Price”) equal to 100.0% of the principal amount thereof plus the Applicable Premium (as defined below) as of, and accrued but unpaid interest, if any, to, the Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the Redemption Date pursuant to Section 307 of the Indenture).

“Applicable Premium” means, with respect to a November 2019 Note at any Redemption Date, the greater of (i) 1.00% of the principal amount of such November 2019 Note and (ii) the excess of (A) the present value at such Redemption Date, calculated as of the date of the applicable redemption notice, of (1) the redemption price of such November 2019 Note on December 1, 2022 (such redemption price being that described in Section 6(a)), plus (2) all required remaining scheduled interest payments due on such November 2019 Note through such date (excluding accrued and unpaid interest to the Redemption Date), computed using a discount rate equal to the Treasury Rate plus 50 basis points, over (B) the principal amount of such November 2019 Note on such Redemption Date. Calculation of the Applicable Premium will be made by the Issuer or on behalf of the Issuer by such Person as the Issuer shall designate; provided that such calculation shall not be a duty or obligation of the Trustee.

“Treasury Rate” means, with respect to a Redemption Date, the weekly average yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15(519) that has become publicly available at least two Business Days prior to the date of the applicable redemption notice (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from such Redemption Date to December 1, 2022; provided, however, that if the period from the Redemption Date to such date is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from the Redemption Date to such date is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

(d) Notwithstanding clauses (a), (b) and (c) of this Section 6, in connection with any tender for the November 2019 Notes, if Holders of not less than 90.0% in the aggregate principal amount of the outstanding November 2019 Notes (including the principal amount of any Additional November 2019 Notes, or any other Additional Notes of the same series as the November 2019 Notes) validly tender and do not withdraw such Notes in such tender offer and

the Issuer, or any other Person making such tender offer, purchases all of the November 2019 Notes (including any Additional November 2019 Notes and any Additional Notes of the same series as the November 2019 Notes) validly tendered and not withdrawn by such Holders, the Issuer will have the right, upon notice given not more than 30 days following such purchase pursuant to such tender offer, to redeem all of the November 2019 Notes that remain outstanding following such purchase at a price in cash equal to the price offered to each Holder in such tender offer, plus, to the extent not included in the tender offer payment, accrued and unpaid interest to but excluding the Redemption Date.

(e) Any redemption of Notes pursuant to this Section 6 may be made upon notice sent electronically or, at the Issuer’s option, mailed by first-class mail to each Holder’s registered address in accordance with Section 1005 of the Indenture, and, if applicable, the Issuer should notify the Trustee of such redemption date, and the principal amount of Notes to be redeemed in accordance with Section 1003 of the Indenture. The Issuer may provide in any redemption notice that payment of the redemption price and the performance of the Issuer’s obligations with respect to such redemption may be performed by another Person.

(f) Any redemption of Notes pursuant to this Section 6 (including in connection with an Equity Offering) or notice thereof may, at the Issuer’s discretion, be subject to the satisfaction (or, waiver by the Issuer in its sole discretion) of one or more conditions precedent, which may include consummation of any related Equity Offering or the occurrence of a Change of Control. If such redemption or notice 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 (including more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) 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 (or, in the Issuer’s sole determination, may not be) satisfied (or waived by the Issuer in its sole discretion) by the Redemption Date, or by the Redemption Date so delayed.
