from time to time by the Issuers (subject to the Issuers’ compliance with Section 4.09 of the Indenture) without notice to or consent of the Holders and shall be consolidated with and form a single class with the Initial Notes and, except
as set forth therein, shall have the same terms as to status, redemption or otherwise as the Initial Notes; 
 WHEREAS, the Issuers and the
Guarantors desire to execute and deliver this Supplemental Indenture for the purpose of issuing an additional $180,000,000 aggregate principal amount of 6.750% Senior Notes due 2025, having terms substantially identical in all material respects to

WHEREAS, Section 9.01 of the Indenture provides that, among other things, the Issuers, the Guarantors and the Trustee may supplement the
Indenture without the consent of any Holder to provide for the issuance of Additional Notes in accordance with the terms of the Indenture. 

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged,

May 1, 2017. The Initial Notes and the Additional 2025 Notes shall be treated as a single class for all purposes under the Indenture. 

(3) Special Record Date. Notwithstanding anything to the contrary in the Indenture, the record date for the payment of
accrued and unpaid interest in respect of the Additional 2025 Notes on December 1, 2017 shall be November 27, 2017. 

(4) Necessary Actions. Each of the Issuers and the Guarantors hereby represents and warrants that all actions necessary
