benchmark floor on such Other Term Loans, such adjustment shall be effected (to such extent) solely through an increase in the interest rate benchmark floor of the Initial Senior Lien Term Loans (or if no interest rate benchmark floor applies to the
Initial Senior

This Agreement shall apply and be effective only with respect to the provisions of the Credit Agreement specifically referred to herein. After the Incremental Facility Effective Date, any reference to the Credit Agreement shall mean the Credit
Agreement as modified hereby.

continue to be in full force and effect and shall accrue to the benefit of the Secured Parties (including in respect of the Incremental Term Loan Lenders). Each of the Reaffirming Loan Parties agrees that, neither the modification of the Credit
Agreement effected pursuant to the Agreement nor the execution, delivery, performance or effectiveness of this Agreement (a) impairs the validity, effectiveness or priority of Liens granted pursuant to any Loan Document, and such Liens continue
unimpaired with the same priority to secure repayment of all Obligations (as defined in the Guarantee and Collateral Agreement and including the Incremental Term Loan), whether heretofore or hereafter incurred or (b) require that any new
filings be made or other action taken to perfect or to maintain the perfection of such Liens. Each of the Reaffirming Loan Parties further agrees to take any action that may be required or that is reasonably requested by the Administrative Agent to
effect the purposes of this Agreement, the transactions contemplated hereby or the Loan Documents and hereby reaffirms its obligations under each provision of each Loan Document to which it is party.

 This
Solvency Certificate is being executed and delivered pursuant to Section 4.2(f) of that certain Credit Agreement dated as of November 9, 2015, among T-Mobile USA, Inc., a Delaware corporation (the

increase their First Amendment Incremental Term Loan Commitments under the First Amendment Incremental Term Loan Facility in the aggregate principal amount of $1,340,000,000 and the Second Amendment Incremental Term Loan Lenders have agreed to

	4.	The Borrower and its Subsidiaries, on a consolidated basis after giving effect to the Transaction, have not incurred and do not intend to incur, or believe that they will incur, debts or other liabilities, including
current obligations, beyond their ability to pay such debts or other liabilities as they become due (whether at maturity or otherwise). 

  

	5.	For purposes of this Solvency Certificate, the amount of any contingent liability has been computed as the amount that, in light of all of the facts and circumstances existing as of the date hereof, represents the
amount that can reasonably be expected to become an actual or matured liability. 

  

	6.	In reaching the conclusions set forth in this Solvency Certificate, the undersigned has (i) reviewed the Credit Agreement and other Loan Documents referred to therein and such other documents deemed relevant and
