On May 10, 2011, MetroPCS Wireless, Inc. (the “Borrower”), an indirect, wholly-owned subsidiary of MetroPCS Communications, Inc. (“Communications”), entered into an Incremental Commitment Agreement, dated May 10, 2011 (the “Incremental Agreement”), by and among the Borrower, Communications, MetroPCS, Inc., a direct wholly-owned subsidiary of Communications, all wholly-owned subsidiaries of the Borrower, and JPMorgan Chase Bank N.A., as administrative agent (as such, the “Administrative Agent”) and as the incremental term lender. The Incremental Agreement supplements the Third Amended and Restated Credit Agreement, dated as of March 17, 2011 (the “2011 Credit Agreement”; unless otherwise defined herein, terms defined in the 2011 Credit Agreement and used herein shall have the meanings given to them in the 2011 Credit Agreement), among the Borrower, the banks and other financial institutions or entities party thereto from time to time as lenders, the Administrative Agent and the other agents and arrangers party thereto, to provide for an additional $1.0 billion of Tranche B-3 Term Loans (the “Incremental Terms Loans”), which amount was borrowed on May 10, 2011. The Borrower intends to use the proceeds of the Incremental Term Loans to prepay all of the existing Tranche B-1 Term Loans, with the remaining proceeds to be used for general corporate purposes, including opportunistic spectrum acquisitions.

The Incremental Term Loans will mature on March 17, 2018 (which is the same maturity date as the existing Tranche B-3 Term Loans), and will require quarterly principal amortization payments of $2.5 million. The interest rate payable on the Incremental Term Loans is LIBOR + 3.75% (which is the same interest rate as the existing Tranche B-3 Term Loans).

The Incremental Agreement did not modify the interest rate, maturity date or any of the other terms of the 2011 Credit Agreement applicable to the Tranche B-2 Term Loans or the existing Tranche B-3 Term Loans.

This description of the Incremental Agreement is a summary only and is qualified in its entirety by the full and complete terms of the Incremental Agreement, a copy of which is attached as an exhibit hereto and incorporated herein by reference.

The information contained in Item 1.01 is incorporated by reference in its entirety into this Item 2.03.
