NEW YORK – August 2, 2004- SIRIUS (NASDAQ: SIRI), the premium satellite radio provider known for delivering the very best in commercial-free music and sports programming to cars and homes across the country, today announced that surfing legend Kelly Slater will launch his own radio show on SIRIUS Faction, the innovative music channel created especially for action sports enthusiasts.

Slater is a six-time world champion and holds more surfing titles than anyone in the world. Often referred to as the “Michael Jordan of surfing,” Slater also has recorded an album with Sony Music, developed his own video game and penned an autobiography, Pipe Dreams: A Surfer’s Journey, a recent New York Times best seller.

On his new SIRIUS show, Kelly Slater’s Radio K-OS, Slater will play music from Jack Johnson, G. Love and other artists who inspire him. Slater will also interview musicians and the surfing world’s biggest names. The show will air on SIRIUS Faction, channel 28, starting Sunday, August 22 at 9pm ET.

Slater says, "Are you SIRIUS? Radio K-OS is getting set to take over the world ... or at least one hour a week on Faction."

“Kelly Slater is a unique athlete, musician and soulful human being,” said Scott Greenstein, SIRIUS’ President of Entertainment and Sports. “His varied talents are a perfect match for Faction, which also combines music and action sports, blended with humanity for a powerful listening experience.”

Slater becomes SIRIUS Faction’s second celebrity host, joining skateboarding legend Tony Hawk. Hawk recently launched his weekly show Tony Hawk’s Demolition Radio heard exclusively on SIRIUS. Over the next few months SIRIUS will roll out additional star athletes who will join Faction’s on-air team.
