ACCLAIMED RADIO EXECUTIVE STEVE HARRIS JOINS XM'S PROGRAMMING TEAM

National, October 05, 2000 -- Award-winning ABC Radio Networks executive Steve Harris has joined XM Satellite Radio (Nasdaq: XMSR) as Vice President, External Programming. He will supervise all content provided by XM's brand-name programming partners, including BBC World Service and BBC Concerts, BET, Radio One, One-On-One Sports, CNN/Sports Illustrated and CNN Financial Network, Bloomberg, Hispanic Broadcast Corporation, C-SPAN Radio, and others. XM will offer digital-quality sound, coast-to-coast service and up to 100 channels to cars and homes beginning in the first half of 2001. Seventy percent of the channels will be produced in-house by the XM Originals programming team and 30 percent will come from brand name third party content providers. All the channels will be created or integrated at the XM Broadcast Center in Washington, D.C., the largest all digital facility of its kind in the U.S. with 82 studios.

Harris comes to XM from ABC Radio Networks, based in Dallas, Texas, where he was Vice President, Urban Programming at ABC Radio, overseeing ABC Radio Networks urban radio products, including nationally syndicated programs such as The Tom Joyner Show, The Doug Banks Show and 24-hour formats such as Classic R&B.

"During his 25-year career in radio, Steve has earned widespread acclaim for his ability to program winning radio stations, as well as a strong reputation for working with top talent," said Lee Abrams, XM's Chief Programming Officer. "Steve will add a level of depth and integrity to our programming team and bring a new dimension to XM's broadcast mission," added Abrams.

In 1999, Harris was named one of the "Top 25 Most Successful African Americans in Radio" by Radio Ink Magazine. He has also received several prestigious industry honors, including the exclusive Black Radio "Drummer Award," and the Young Black Programmer's "Programmer of the Year" award.

"XM is completely revolutionizing radio as we know it today. After working in traditional radio for more than two decades, I wouldn't have missed the opportunity to join forces with a company that is taking radio to a whole new level," said Harris.

XM-Ready radios will be manufactured by such household names as Sony, Alpine and Pioneer Electronics Corporation and sold by automotive and retail outlets such as Best Buy and Circuit City. The company has a long-term distribution agreement with General Motors to integrate XM-Ready radios into its vehicles commencing in 2001. XM's strategic investors include America's leading car, radio and satellite TV companies -- General Motors, American Honda Motor Co. Inc., Clear Channel Communications, DIRECTV and Motient Corporation (Nasdaq: MTNT), which holds a controlling interest in the company.
