Following the Mergers, T-Mobile US contributed Sprint to T-Mobile USA, Inc.

WHEREAS, upon consummation of the T-Mobile Transaction, Sprint became an indirect wholly owned subsidiary of T-Mobile US;

WHEREAS, in connection with the consummation of the T-Mobile Transaction, the parties wish to provide that each New Guarantor will provide an irrevocable and unconditional guarantee in respect of each series of Notes;

WHEREAS, the guarantees of each New Guarantor constitute a direct benefit to such New Guarantor and will be in furtherance of the corporate purposes of such New Guarantor or necessary or convenient to the conduct, promotion or attainment of the business of such New Guarantor and, accordingly, in consideration therefor, each New Guarantor is willing to guarantee the Notes on the terms set forth herein; and

WHEREAS, pursuant to Section 901(10) of the Base Indenture, the Trustee is authorized to execute and deliver this Fifth Supplemental Indenture without the consent of the Holders of the Notes to make the changes described below that do not adversely affect the interests of the Holders in any material respect.

WHEREAS, for the purposes hereinabove recited, and pursuant to due corporate action, the Company has duly determined to execute and deliver to the Trustee this Fifth Supplemental Indenture; and

WHEREAS, all conditions and requirements necessary to make this Fifth Supplemental Indenture a valid and binding instrument in accordance with its terms have been done and performed, and the execution and delivery hereof have been in all respects duly authorized.

NOW, THEREFORE, in consideration of the premises, the covenants and other agreements contained herein and other good and valuable consideration, the sufficiency of which is hereby confirmed, the New Guarantors, the Company, Sprint, Sprint Communications, and the Trustee mutually covenant and agree as follows:

1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Base Indenture.

2. Agreement to Guarantee. Each New Guarantor hereby agrees to and does hereby, jointly and severally, irrevocably and unconditionally guarantee, on a senior unsecured basis, the full and punctual payment when due, whether at maturity, by acceleration or otherwise, all payment obligations of the Company under the Notes for the payment of principal of, premium, if any, and interest on the Notes, and all other amounts payable by the Company to the Holders of the Notes under the Notes, the Indenture and this Fifth Supplemental Indenture (each a “Guarantee” and, together, the “Guarantees”). Each Guarantee is limited to the maximum

2

amount that can be guaranteed by law or without resulting in the Guarantee being voidable or unenforceable under applicable laws relating to fraudulent transfer, or under similar laws affecting the rights of creditors generally. Each Guarantee shall be automatically and unconditionally released (and thereupon shall terminate and be discharged and be of no further force and effect) upon the Company exercising its legal defeasance or covenant defeasance option pursuant to Article XIII of the Base Indenture or the satisfaction and discharge of the obligations of the Company with respect to the Notes pursuant to Article IV of the Base Indenture, each in compliance with the terms of the Indenture. For the avoidance of doubt (other than as expressly provided in the Indenture), nothing in this Fifth Supplemental Indenture shall prevent any New Guarantor from merging with and into the Company, or the Company from merging with and into any New Guarantor, and in such event the applicable Guarantee shall terminate and the surviving entity shall remain the primary obligor under the Notes, the Indenture and this Fifth Supplemental Indenture. Furthermore, for the avoidance of doubt (other than as expressly provided in the Indenture), nothing in this Fifth Supplemental Indenture shall prevent any Guarantor from merging with and into any other Guarantor, and in such event the guarantee of the surviving entity shall remain in full force and effect and the guarantee of the non-surviving entity shall terminate. Each New Guarantor shall be subrogated to all rights of the Holders of the Notes against the Company in respect of any amounts paid by such New Guarantor pursuant to the Guarantee; provided, however, that such New Guarantor shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until the principal of, premium, if any, and interest on all Notes shall have been paid in full or payment thereof shall have been provided for in accordance with the provisions of the Indenture. For the avoidance of doubt, in the event of a default in payment by the Company, legal proceedings may be instituted against any New Guarantor to enforce the Guarantee without first proceeding against the Company.

3. Effect of Fifth Supplemental Indenture ; Conflicts With Indenture. This Fifth Supplemental Indenture is executed by the New Guarantors, the Company, the Existing Guarantors and the Trustee upon the Company’s request, pursuant to the provisions of the Base Indenture, and the terms and conditions hereof shall be deemed to be part of the Base Indenture for all purposes. The Base Indenture, as amended and supplemented by this Fifth Supplemental Indenture, is in all respects hereby adopted, ratified and confirmed. Notwithstanding the foregoing, to the extent that any of the terms of this Fifth Supplemental Indenture are inconsistent with, or conflict with, the terms of the Base Indenture, the terms of this Fifth Supplemental Indenture shall govern.

4. No Personal Liability of Directors, Officers, Employees and Stockholders of the New Guarantors. No director, officer, employee, incorporator or stockholder of any New Guarantor, as such, shall have any liability for any obligations of the Company, the New Guarantors or the Existing Guarantors, any guarantee under any series of Notes, the Indenture, any Officers’ Certificates or this Fifth Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability.

5. Governing Law. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THIS FIFTH 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.

7. Effect Of Headings. The Headings of the Sections of this Fifth Supplemental Indenture have been inserted for convenience of reference only, are not to be considered a part of this Fifth Supplemental Indenture and will in no way modify or restrict any of the terms or provisions hereof.

8.
