Capitalized terms used herein and not otherwise defined shall have the meanings assigned to them in the Indenture (as defined below).

W I T N E S S E T H

WHEREAS, SGMS Escrow Corp., a Delaware corporation (the “Escrow Issuer”) has heretofore executed and delivered to the Trustee an indenture dated as of November 21, 2014 (the “Initial Indenture” as supplemented by this Supplemental Indenture, the “Indenture”) relating to the Escrow Issuer’s 7.000% Senior Secured Notes due 2022 (the “Securities”);

WHEREAS, on the date hereof, the Escrow Issuer is merging with and into SGI, with SGI being the surviving Person of such merger and the Escrow Issuer ceasing to exist (the “Merger”); 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 parties to this Supplemental Indenture mutually covenant and agree for the equal and ratable benefit of the Holders of the Securities as follows:

1.ASSUMPTION OF OBLIGATIONS. Effective upon consummation of the Merger, the Company, pursuant to Article 5 of the Indenture, hereby expressly assumes and agrees to pay, perform and/or discharge when due each and every debt, obligation, covenant and agreement incurred, made or to be paid, performed or discharged by the Escrow Issuer under the Indenture and the Securities. The Company hereby agrees to be bound by all the terms, provisions and conditions of the Indenture and the Securities to which Escrow Issuer was theretofore bound and, as the Surviving Entity, shall succeed to, and be substituted for, and may exercise every right and power of, the Escrow Issuer under the Indenture and the Securities, and the Escrow Issuer is relieved of all of its obligations and duties under the Indenture and the Securities.

2.AGREEMENT TO GUARANTEE. Each Supplemental Guarantor hereby agrees, jointly and severally with all other Supplemental Guarantors, and fully and unconditionally, to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Guarantee and in the Indenture including but not limited to Article 10 thereof.

3.NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator, stockholder or controlling person of the Company or any Supplemental Guarantor, as such, shall have any liability for any obligations of the Company or any Supplemental Guarantor under

the Securities, any Guarantees, the Indenture or this Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Securities by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities.

4.NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

5.COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. The exchange of copies of this Supplemental Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Supplemental Indenture as to the parties hereto and may be used in lieu of the original Supplemental Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.

6.EFFECT OF HEADINGS. The section headings herein are for convenience only and shall not affect the construction hereof.
