SIRIUS SATELLITE RADIO TO BEAM FROM BOTH COASTS WITH ADDITION OF LOS ANGELES STUDIOS
Selected SIRIUS Music and Talk Programs Will Originate From New Los Angeles Studios

NEW YORK - December 17, 2004 - SIRIUS Satellite Radio (NASDAQ: SIRI) will soon have a presence on both US coasts, with the establishment of new Los Angeles studios in early 2005.

SIRIUS' Los Angeles operations will be centered in the studios of Swinghouse, a facility currently used by many top artists as a rehearsal and recording studio, located in Hollywood, CA.

Acquiring the studio space provides SIRIUS the flexibility to broadcast from both the East and West coasts, according to Jay Clark, SIRIUS Executive Vice President of Programming. SIRIUS produces its premium, proprietary content and hosts daily visits by musicians and celebrities in all areas of entertainment from its national broadcast studios in Rockefeller Center, in the heart of New York City, and also has studios in Houston, Texas; Nashville and Memphis, Tennessee; and Daytona Beach, Florida.

"Along with New York and Nashville, Los Angeles is a world-class talent mecca," said Clark. "This moves SIRIUS another step forward in developing the greatest national audio entertainment platform available."

The exclusive SIRIUS programs which may be produced at the company's Swinghouse studio include those hosted by celebrity athletes Tony Hawk, Kelly Slater, Kerri Walsh and Bode Miller, and Viva La Bam creator and star Bam Margera, all of which are heard on Faction // Channel 28 - the innovative music channel designed for action sports enthusiasts; and talk programs such as Los Angeles-based The Young Turks, broadcast on SIRIUS Left // Channel 143.

SIRIUS talent currently based in the Los Angeles area includes Totally '70s // Channel 7 host and The Brady Bunch star Barry Williams; female rapper MC Lyte, a DJ on Hot Jamz // Channel 50; and Richard Blade, Freddy Snakeskin and Swedish Egil, all of whom are on-air personalities on First Wave // Channel 22.

Among the many recording and performing artists who have used Swinghouse are the Goo Goo Dolls, Red Hot Chili Peppers, Ozzy Osbourne, Green Day and Tom Petty & The Heartbreakers.
