NEW YORK - September 22, 2005 - SIRIUS Satellite Radio (NASDAQ: SIRI), which offers more live sports play-by-play than any other radio source with live coverage of more than 250 professional and college teams, together with CSTV: College Sports Television, Conference USA and the Mountain West Conference, announced today an agreement to broadcast two college football "Games of the Week," one each from Conference USA and the Mountain West Conference, on SIRIUS throughout the season.  In addition to the "Games of the Week," other C-USA and MWC games may be heard on SIRIUS over the course of the season.  Schedules are available at www.sirius.com.

Mountain West Conference football games will feature Air Force, BYU, Colorado State, New Mexico, San Diego State, TCU, UNLV, Utah and Wyoming.  The next game scheduled to air on SIRIUS is Air Force @ Utah tonight, September 22. The game will air on SIRIUS channel 123.  Conference USA teams include East Carolina, Houston, Marshall, Memphis, Rice, SMU, Southern Mississippi, Tulane, Tulsa, UAB, UCF and UTEP. The next CUSA game to air on SIRIUS will be Memphis @ Tulsa this Saturday, September 24 on SIRIUS channel 110.

"Conference USA and the Mountain West Conference are great additions to our sports lineup," said Steve Cohen, Vice President of Sports Programming for SIRIUS.  "SIRIUS is a premier destination for college sports fans and these partnerships with CSTV and the conferences certainly enhance that appeal across a large and widespread fan base."

"We are very pleased that people all over the country will be able to listen to Conference USA games this season through SIRIUS Satellite Radio," said Conference USA Commissioner Britton Banowsky.  "This is just another great example of how we have broadened our distribution this year and how CSTV is reaching out to give our fans unprecedented access to follow their favorite teams."

"CSTV has the ideal `fans first' focus. The agreement with Sirius is just another example of how Mountain West fans will hear and see more MWC sports at better times and in more media platforms than ever before," said Craig Thompson, MWC Commissioner.  "Having MWC games accessible on satellite radio is a tremendous benefit to our fans."

"We're delighted that Sirius recognizes the huge appetite that college fans have for accessing games in every way, including on satellite radio," said Chris Bevilacqua, President, CSTV Networks.  "Sirius subscribers now can enjoy football games featuring our partners at Conference USA and the Mountain West Conference."

CSTV and Conference USA have kicked off the first year of a long-term multimedia and marketing relationship that includes significant national, regional and local exposure for football, men's and women's basketball and all other C-USA sports.  CSTV is televising 55 C-USA football games live this fall, and provides distribution via pay per view, broadband video and audio-on-demand, satellite radio, cable/broadcast/satellite television wireless and more. 

CSTV becomes the official television partner for the Mountain West Conference in 2006. The MWC forged an agreement with CSTV, giving the fastest-growing independent cable network exclusive rights to Mountain West Conference football and men's basketball, plus coverage for all other MWC sports. 

SIRIUS airs sports play-by-play from more than 125 college and university partners around the nation and will broadcast every game in its entirety of the 2005, 2006 and 2007 NCAA Division I Men's Basketball Championship.  In addition to being the official satellite radio partner of the NFL, NHL, Wimbledon Championships and Barclays English Premier League soccer, SIRIUS provides sports news and talk, play-by-play action from the NBA and coverage of several of the year's top thoroughbred horse races.  Starting in 2007, SIRIUS will be the official satellite radio home of NASCAR.
