WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of January 27, 2023, providing for the issuance of 11.750% Senior Second Lien Notes due 2026 (the “Notes”);

WHEREAS, pursuant to Section 9.01 of the Indenture, the Company and the Trustee are authorized to execute and deliver this Supplemental Indenture without the consent of Holders.

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