WHEREAS, the Issuers, the Guarantors and the Trustee are parties to that certain Indenture dated as of June 4, 2015 (the “Original Indenture”), relating to the Notes;

WHEREAS, Section 9.01(d) of the Original Indenture provides that the Issuers, the Guarantors and Trustee, without the consent of the Holders, may amend or supplement the Original Indenture to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any such Holder, provided that any change to conform this Indenture to the Offering Memorandum shall not be deemed to adversely affect such legal rights;

WHEREAS, the Issuers and the Guarantors desire and have requested the Trustee to join with them in entering into this Supplemental Indenture for the purpose of amending the Indenture in certain respects as permitted by Section 9.01(d) of the Original Indenture;

WHEREAS, the Issuers and the Guarantors have determined that Global Operating was inadvertently omitted from the signature page of the Original Indenture as a guarantor of the Notes, which resulted in the definition of the “Guarantors” in the Original Indenture being inconsistent with the definition of the same, contained in the Offering Memorandum;

WHEREAS, the Issuers have delivered to the Trustee simultaneously with the execution and delivery of this Supplemental Indenture an Officers’ Certificate and Opinion of Counsel relating to this Supplemental Indenture as contemplated by Sections 11.04 and 11.05 of the Original Indenture; and
