Washington D.C., January 06, 2000 -- XM Satellite Radio (NASDAQ:XMSR) and the National Association for Stock Car Auto Racing (NASCAR), the #1 spectator sport in America, today announced a strategic alliance to create the nation's first 24-hour, seven-day-a-week, all-NASCAR radio channel exclusively for XM RadioTM, making NASCAR the first sports property to announce a satellite radio partnership. The exclusive agreement also includes a strategic marketing relationship giving XM Radio an extensive sales/merchandising presence at each NASCAR event. The announcement was made by Hugh Panero, President and CEO of XM Satellite Radio Inc., and Brian France, Senior Vice President for NASCAR, at the outset of the Consumer Electronics Show in Las Vegas, Nevada.

NASCAR is also the fastest growing sport in America. In 1998, more than 11 million people attended NASCAR races and 252 million watched its events on television. Powered by stars like Jeff Gordan, Dale Earnhardt, Dale Jarrett and Terry Labonte, the sport's popularity is unquestioned. This was underscored in November 1999, when NASCAR signed a $2.4 billion television deal with Fox, NBC and TBS - one of the highest dollar-values for the television rights to any sport in the US. The XM NASCAR channel will focus on the total NASCAR lifestyle and experience: the races, cars, drivers, fans, collectibles, behind-the-scenes interviews and features, and in-depth analysis of all NASCAR events.

"The agreement with XM Radio, like the television consolidation agreement with Fox, NBC and Turner Sports, captures our vision of the sport of NASCAR's future," said France. "All of the new media ventures being pursued by NASCAR are reflective of the strategic values that have been created for the sport in recent years. Additionally, the new media agreements that have been announced or will be announced throughout the 2000 season will showcase NASCAR racing to millions of sports fans like never before, providing fans with an interactive experience and bringing them closer to NASCAR in ways they could have never imagined."

"We are thrilled about this unique collaboration," said Mr. Panero. "NASCAR is a way of life for millions of fans, who are among the most loyal and enthusiastic in the country, if not the world. The interests of a NASCAR fan and a future XM Radio subscriber are synonymous: they love their cars and their music with equal passion. XM Radio is committed to offering this dynamic audience an unprecedented selection of programming options around the clock, including in depth features, interviews and information related to NASCAR."

Incorporated in 1948, NASCAR today runs more than 2,200 events a year at 135 tracks across the United States, including the sport's premier event, the Daytona 500. The sport's popularity extends to NASCAR's growing family of publications, products, and online and radio programming. For more information, please visit
