SIRIUS' F1 schedule kicks off this weekend with live coverage of the
Monaco Grand Prix in Monte Carlo (Sunday, May 25 at 8:00 am ET), one of the
world's most prestigious and challenging motor racing events, exclusively on
SIRIUS channel 125. Often referred to as the crown jewel of F1, the Monaco
Grand Prix is one of the only street circuits in use. SIRIUS will broadcast
the entire remainder of the 2008 calendar's races live nationwide on SIRIUS
125, including the first-ever F1 night race, being held in Singapore on
September 28.

"We are very happy to be associated with SIRIUS Satellite Radio, and that
they will broadcast our races into North America," said Bernie Ecclestone,
Chief Executive of Formula One Management.

"FORMULA 1 is a worldwide spectacle, blending international backdrops and
advanced automotive technology from some of the best brands in motor racing
with extremely talented drivers racing the world's most challenging
circuits," said Scott Greenstein, SIRIUS' President of Entertainment and
Sports. "SIRIUS is thrilled to deliver the high-profile excitement of F1 to
our subscribers, with live coverage of races from each exotic location,
giving North American racing fans unprecedented access to this unique sport."

The FIA FORMULA 1 WORLD CHAMPIONSHIP is the highest end of open wheeled
motor racing and a single season can consist of a series of 18 races, known
as Grands Prix, run from March to November on road course circuits, and in a
few cases on closed city streets. The cars race at high speeds, exceeding 200
mph, and the results of each race are combined to determine two annual World
Championships, one for drivers and one for constructors (teams).

The reigning drivers' champion is FERRARI driver Kimi Raikkonen of
Finland, who is currently the top points holder this season (35), ahead of
FERRARI driver Felipe Massa of Brazil (28) and MCLAREN/MERCEDES driver Lewis
Hamilton of Great Britain (28). The reigning constructor's champion is
SCUDERIA FERRARI.
