SIRIUS TO ADD MORE SHOWS FROM NATIONAL PUBLIC RADIO

Satellite Radio Programs Will Feature Classical Music

NEW YORK – May 8, 2003 – SIRIUS (NASDAQ: SIRI), the premier satellite radio broadcaster and only service delivering uncompromised Coast-to-coast music and entertainment for your car and home, today announced plans to add two highly regarded NPR programs to its classical music streams. NPR’s Performance Today and SymphonyCast will be broadcast on SIRIUS Symphony Hall // 80 and Vista // 82.

“SIRIUS has proven to be a great place for our programs,” said Margaret Low Smith, Vice President for Programming, NPR. “New shows, like The Tavis Smiley Show and The Motley Fool Radio Show were part of the NPR SIRIUS lineup from day one. We value our successful partnership with SIRIUS, and we look forward to providing their listeners with exceptional NPR programs as the service continues to grow.”

Performance Today, NPR’s Peabody award-winning daily classical music program, features concert performances from around the world. The two-hour show is hosted by Fred Child, and recreates the thrill of LIVE concerts by world-renowned artists in concert halls around the globe, without the cost or hassle of purchasing a ticket. “This show reflects NPR music and arts programming at its best,“ said Kaaren Hushagen, Classical Genre Manager for SIRIUS. “It is one of NPR’s musical gems.”

SymphonyCast, hosted by Korva Coleman, is the first NPR concert program to bring signature performances by the world’s finest orchestras into one comprehensive weekly series. Coleman describes SymphonyCast as “a music show, but with a real story to the music. Whether it’s the sweep of a Mahler symphony, the emotion of a conductor’s farewell or the excitement of inaugurating a brand new hall, each program is an event, combining the personalities and the passion behind some of the world’s greatest music.” The two-hour show will air once per week.

“We are delighted to offer these additional programs to our subscribers,” said Joseph P. Clayton, President and CEO of SIRIUS. “NPR is one of our premiere partners, and we look forward to developing – and premiering – more programming content with them in the future.”
