agreements contained herein and other good and valuable consideration, the sufficiency of which is hereby confirmed, the Company, the New Guarantors and the Trustee mutually covenant and agree for the equal and ratable benefit of the Trustee and 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 Base Indenture. 
 2. Agreement to Guarantee. Each New Guarantor hereby agrees to 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 Trustee and the Holders of the Notes under the Notes, each Indenture and this Sixteenth Supplemental Indenture (each a “Guarantee”

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 applicable Indenture. For the avoidance of doubt, (other than as expressly provided in the applicable Indenture) nothing in this Sixteenth Supplemental Indenture shall prevent any New Guarantor from merging
with and into the Company or Sprint, or the Company or Sprint from merging with and into any New Guarantor, and in such event such Guarantee of such New Guarantor shall terminate and the surviving entity shall remain the primary obligor under the
Notes, the Indenture and this Sixteenth Supplemental Indenture. Furthermore, for the avoidance of doubt (other than as expressly provided in the applicable Indenture), nothing in this Sixteenth 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 Guarantees; 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. 
 3. Effect of Supplemental Indenture; Conflicts With Indenture. This Sixteenth Supplemental
Indenture is executed by each New Guarantor, the Company, Sprint and the Trustee upon the Company’s request, pursuant to the provisions of each Indenture, and the terms and conditions hereof shall be deemed to be part of each Indenture for all
purposes. The Indenture, as amended and supplemented by this Sixteenth Supplemental Indenture, is in all respects hereby adopted, ratified and confirmed. Notwithstanding the foregoing, to the extent that any of the terms of this Sixteenth
Supplemental Indenture are inconsistent with, or conflict with, the terms of any Indenture, the terms of this Sixteenth Supplemental Indenture shall govern. 

  
 3 

 4. No Personal Liability of Directors, Officers, Employees and Stockholders of the New
Guarantors. No director, officer, employee, incorporator or stockholder of any New Guarantors, as such, shall have any liability for any obligations of the Company, Sprint, the New Guarantors or any guarantor under any series of Notes, any
guarantees under any series of Notes, any Indenture or this Sixteenth 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
SIXTEENTH 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. 

6. Counterparts. The parties may sign any number of copies of this Sixteenth Supplemental Indenture. Each signed copy shall be an
original, but all of them together represent the same agreement. 
 7. Effect of Headings. The headings of the sections of this
Sixteenth Supplemental Indenture have been inserted for convenience of reference only, are not to be considered a part of this Sixteenth Supplemental Indenture and will in no way modify or restrict any of the terms or provisions hereof. 

8. The Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this
Sixteenth Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the New Guarantors, the Company and Sprint.
