Sirius Satellite Radio To Launch Weekly Talk Show Created And Hosted By Former Senator Bill Bradley

"American Voices" will Debut on SIRIUS Satellite Radio in May

NEW YORK - April 13, 2005 - SIRIUS Satellite Radio (NASDAQ: SIRI) today announced that former U.S. Senator Bill Bradley will be the host and creator of American Voices, a weekly talk show that will feature varied stories, personalities and opinions from a broad cross section of America and the world. The show launches in May on SIRIUS Talk Central, channel 148.

Having traveled the country extensively for over forty years as a professional basketball player, U.S. Senator, and former Presidential candidate, Bradley plans to have guests on his show as varied as the ones he has met on the road. From athletes and writers to entrepreneurs and community leaders, Bradley's show will reflect the wide spectrum of people, places, and politics that make up the American landscape.

Bradley says, "I will not just be interviewing my guests...I will be having a conversation with them about their lives. The show will strive for a balance between the predictable and the unexpected." Bradley is quick to explain that the show is non-partisan. "American Voices will focus on the common humanity of our citizens and will recognize those extraordinary individuals who make a difference in their communities."

A native of Crystal City, Missouri, Bradley graduated from Princeton University and Oxford University, which he attended as a Rhodes Scholar. He also won a gold medal with the U.S Olympic basketball team in 1964. After graduation, Bradley played ten years with the New York Knicks, during which time the team won two NBA championships in 1970 and 1973. He was inducted into the Basketball Hall of Fame in 1982.

Bradley served in the U.S Senate from New Jersey from 1979 to 1997, where he focused on issues such as tax reform, international trade and race relations. He opted not to run for a fourth term in 1996 but returned to the political arena in 2000 when he ran for the Democratic nomination for President.

Bradley currently serves as a Managing Director at Allen & Company. He is also an accomplished author and has written five books including the New York Times best-sellers Time Present, Time Past: A Memoir and Values of the Game.

"Bill Bradley is a unique icon on the American landscape. He holds a wide-ranging perspective of America, all learned through first-hand experience," says Scott Greenstein, SIRIUS President of Entertainment and Sports. "This time he offers America, through SIRIUS, an oasis on radio to talk about the vital and compelling parts of America and to bring listeners insight into the issues of life today."

"For me, radio is a way of connecting with people," says Bradley. "I look forward to hearing and sharing some great stories."
