WHEREAS, the Issuer has heretofore executed and delivered to the Trustee a third supplemental indenture, dated as of August 30, 2019 (the “Third Supplemental Indenture”), among those entities listed in Annex A thereto, as new guarantors, the Issuer, the other Guarantors party thereto (as defined therein) and the Trustee, to accede certain new guarantors under the Notes (the Base Indenture, as supplemented by each of the First Supplemental Indenture, the Second Supplemental Indenture and the Third Supplemental Indenture, herein referred to as the “Indenture”);
WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuer’s obligations under the Notes and the Indenture on the terms and conditions set forth herein (the “Note Guarantee”); and
WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.
NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:
1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.
