Formula and SIRIUS Make Waves with Satellite Radio as Standard Equipment

All 2004 Formula Boats To Include Radio and One Year of SIRIUS Music and Entertainment

DECATUR, IN and NEW YORK — July 30, 2003 — SIRIUS (NASDAQ: SIRI), known for delivering the very best in commercial-free music and premium audio entertainment, and Thunderbird Products/Formula Powerboats, builders of premium family, sport and offshore racing boats, today announced that a SIRIUS Satellite Radio system, and one year of SIRIUS’ premium programming, will be offered as a standard feature on all 2004 Formula powerboats. Formula made the announcement at its annual dealer meeting, themed “Experience the Magic,” being held at the Sanibel Harbor Resort & Spa in Fort Myers, Florida.

In 2003, Formula became the first boat builder to include SIRIUS-ready head units in its boats. For 2004, every Formula boat will be equipped with a complete SIRIUS marine system featuring a Kenwood Marine or Clarion Marine AM/FM/CD/SIRI head unit, with a direct digital interface to a SIRIUS tuner and a Shakespeare marine SIRIUS antenna. All Formula boats will also come bundled with one year of SIRIUS service.

In addition to the inclusion of SIRIUS on all Formula boats, SIRIUS and Formula have agreed to continue their race sponsorship partnership. Formula has provided SIRIUS with a 38-foot Formula offshore race boat to be on display at NASCAR and other events throughout the country, and SIRIUS is a proud sponsor of three Formula factory race teams: Let’s Play Racing, Total Marine Racing, and R & S Racing. SIRIUS/Let’s Play Racing is currently #1 in the APBA Pro-Series Factory 2 Class standings.

"SIRIUS offers the commercial-free premium entertainment that complements the high standards of our boats and boat owners,” said Scott Porter, President of Thunderbird/Formula Boats. “We are excited about continuing our race and display programs with SIRIUS.” Offshore racing featuring the Formula/SIRIUS race teams can be seen regularly on Speed Channel and Outdoor Channel offshore racing programs.

”SIRIUS is proud to continue and expand our association with Thunderbird Formula Boats," said Joseph P. Clayton, President and CEO of SIRIUS. “Our second year with Formula, both with the factory satellite radio offerings and the race sponsorships, is a great win for Formula, SIRIUS and Formula customers.”
