On July 28, 2011, we entered into a new master services agreement with T-Mobile effective July 1, 2011, which covers all services that we provide to T-Mobile. The new master services agreement with T-Mobile has an initial term of five years and will automatically renew for additional one-year periods thereafter, but may be terminated by T-Mobile upon 90 days written notice.

Our work for AT&T is covered by several contracts for a variety of different lines of AT&T business.  These contracts expire between 2014 and 2015.  Our initial master services agreement covering all AT&T work had been extended through January 31, 2013.   On January 25, 2013, we entered into a new master services agreement with AT&T Services, Inc., which expires December 31, 2015 and may be extended upon mutual agreement, but may be terminated by AT&T with written notice.

On January 4, 2014, we signed a new master services agreement with Comcast, effective June 22, 2013, which provides for the same services as the original master services agreement that was signed in 2011 and would have expired in 2014. The new master services agreement covers all services that we provide to Comcast, has an initial term of one year and will automatically renew for additional one-year periods unless either party gives notice of cancellation. Comcast may terminate the agreement upon 90 days written notice.
