SIRIUS Now In Front of More Listeners Than Any Satellite Radio Broadcaster

NEW YORK and DALLAS – May 20, 2004 – SIRIUS, the premium satellite radio provider (NASDAQ: SIRI), known for delivering the very best in commercial-free music and sports programming to cars and homes across the country, today significantly increased its number of listeners across the country when it made its music service available to EchoStar Communications Corporation (NASDAQ: DISH) and its more than 9.7 million DISH Network satellite television customers. The official launch of the service is to take place today at the DISH Network 2004 Team Summit Satellite Television Conference in Dallas.

“Beginning today, SIRIUS is now in front of more listeners than anyone in satellite radio,” said Joseph P. Clayton, CEO of SIRIUS. “More than 9.7 million DISH Network subscribers now have the opportunity to listen to 100 percent commercial-free music from SIRIUS, and can enjoy the tremendous variety of music genres that we provide in digital quality sound. Once they hear what we have to offer, we believe that DISH Network customers will want to have SIRIUS in their cars, boats, RVs and trucks, as well as their homes.”

Subscribers of DISH Network’s premium packages – America’s Top 120, Top 180 and America’s Everything Pak – now receive SIRIUS’ music channels at no extra charge. The remaining DISH Network subscribers have the option to upgrade their subscription packages to include SIRIUS.

“Satellite radio is one of the hottest products, and SIRIUS has the best programming in this exciting new entertainment category,” said Charles Ergen, chairman and CEO of EchoStar. “At DISH Network, we stand for the best in quality, and that’s why we decided to link up with SIRIUS -- to provide our listeners with the most varied music in satellite radio. With over 60 channels of commercial-free music, we believe that SIRIUS has the depth and variety of programming to satisfy our customers.”

In addition to providing DISH Network subscribers with music programming, participating DISH Network retailers around the country will have the ability to offer consumers a DISH Network-branded SIRIUS Satellite Radio receiver. The transportable DISH Network Satellite Radio Receiver SR200 can easily be installed in a car, truck, boat or RV, and can be inserted into a portable speaker “boombox” for trips to the beach or a picnic. The DISH SR200, plus car kit and antenna, will be available through DISH Network retailers at a MSRP price of $149.95. Boombox pricing will be announced at a later date.
