                            IN SIRIUS SATELLITE RADIO

 AUTOMAKER TO INSTALL SATELLITE RECEIVERS IN ITS VEHICLE LINES INCLUDING HEAVY
                             TRUCKS AND LUXURY CARS

AUBURN HILLS, MICH. - FEBRUARY 1, 2000 - DaimlerChrysler (NYSE: DCX) and Sirius
Satellite Radio (Nasdaq: SIRI) today announced an agreement to bring satellite
radio to DaimlerChrysler customers beginning next year.

Sirius Radio will provide DaimlerChrysler customers with seamless coast-to-coast
coverage of up to 100 channels of programming, including 50 channels of
commercial-free music and up to 50 channels of news, sports and entertainment
for a monthly subscription fee of $9.95.

Under the terms of the agreement, DaimlerChrysler Corporation will purchase $100
million of Sirius common stock and exclusively factory-install Sirius receivers
in DaimlerChrysler cars and light trucks.

The arrangement includes all DaimlerChrysler brands sold in the United States,
including Mercedes-Benz, Chrysler, Jeep'r', Dodge, Dodge Truck, as well as
Freightliner and Sterling heavy trucks.

DaimlerChrysler and Sirius will also work together to develop innovative
telematics functions using the Sirius national digital broadcasting system.
These applications may include a range of wireless security, convenience and
navigation services for DaimlerChrysler vehicle owners. This is a further step
in DaimlerChrysler's strategy to create and develop technologies to better serve
its customers.

DaimlerChrysler is North America's third largest auto manufacturer, selling more
than 4.8 million vehicles worldwide per year. Freightliner is North America's
largest heavy-duty truck manufacturer -- and the first truck manufacturer to
agree to install satellite radios in commercial vehicles.

"We believe Sirius Radio has a superior system which will offer our vehicle
owners tailored, commercial-free broadcasts across the country," said Jim
Holden, President, DaimlerChrysler Corporation. "We see this arrangement as part
of DaimlerChrysler's ongoing strategy to expand our business beyond the
traditional automotive manufacturing and sale. This is all about DaimlerChrysler
bringing new value and services to our Chrysler, Jeep and Dodge customers, and
providing innovation in every area of their automotive experience."







"Luxury car owners expect the most advanced performance, information and
entertainment technologies," added Ken Enders, Vice President of Marketing for
Mercedes-Benz USA, Inc. "We believe Sirius Radio will provide our Mercedes-Benz
clients with a revolution in audio information and entertainment."

"It is crucial that our commercial vehicle customers have the most advanced
technologies and the best entertainment options for the long hours spent on the
road," said Jim Hebe, President & CEO of Freightliner Corporation. "We expect
this alliance to usher in a new era of commercial-free music and innovative
news, talk and entertainment radio programming for motorists and truckers across
the U.S."

"We're extremely pleased that one of the world's most respected automakers has
made this significant commitment to our technology, our service and our
company," said David Margolese, Sirius Chairman and Chief Executive. "We believe
this decision affirms the superiority of our proprietary transmission technology
and the power of our completely commercial-free music capability."

Sirius has alliances with eight leading automotive electronics manufacturers to
produce digital receivers for the automotive aftermarket and for installation in
new cars. These companies include Alpine, Audiovox, Clarion, Delphi Delco
Electronics, Kenwood, Panasonic, Recoton, and Visteon.
