NEW YORK -- March 12, 2004 - SIRIUS Satellite Radio (NASDAQ: SIRI) today announced that it has extended the exercise date of the option it granted to Morgan Stanley & Co. Incorporated to purchase up to $50 million in principal amount of its 2½% Convertible Notes due 2009. The option, which was granted to Morgan Stanley & Co. Incorporated, as the initial purchaser, in connection with the company’s offering of $250 million of 2½% Convertible Notes due 2009 last month, will now expire on April 13, 2004 to the extent it is not exercised.

Each $1,000 in principal amount of the notes will be convertible, at the option of the holder, into 226.7574 shares of SIRIUS’ common stock, an effective price of $4.41 per share. SIRIUS plans to use the net proceeds for general corporate purposes.
