NEW YORK - June 5, 2007 — SIRIUS Satellite Radio (NASDAQ: SIRI) today announced that it has obtained a $250 million senior secured term loan commitment from Morgan Stanley Senior Funding, Inc.

The facility will mature in five and one-half years and have covenants substantially similar to those under the Company’s existing 9 5/8% Senior Notes. The proceeds will be used for general corporate purposes.

“This transaction takes advantage of favorable market conditions and significantly strengthens our balance sheet,” said David Frear, EVP and CFO of SIRIUS.
