XM RADIO CLOSES $475 MILLION FINANCING PACKAGE

Company Also Closes Exchange Offer With 92 Percent Participation

Washington D.C., January 28, 2003 -- XM Satellite Radio Inc. (Nasdaq: XMSR) today closed on its $475 million funding package - consisting of $225 million in new funds from strategic and financial investors and $250 million in payment deferrals and related credit facilities from General Motors.

XM also closed its exchange offer with respect to its outstanding 14 percent Senior Secured Notes due 2010. XM had offered its noteholders a package of cash and new securities, including new 14 percent Senior Secured Discount Notes due 2009 and warrants to purchase common stock. Over $300 million, representing 92 percent of the outstanding issue of Existing Notes, were tendered. 25,514,960 warrants, exercisable at $3.18 per share, have been issued to noteholders. The company was advised on these transactions by Bear, Stearns & Co., Merrill Lynch & Co. and Veronis Suhler Stevenson.

"The completion of these financings and refinancings under today's difficult investment conditions is a critical milestone in XM's road to becoming a major entertainment company. The funding acquired, coupled with recent GM/Honda OEM announcements and the marketplace success of new XM receiver products in the retail marketplace, gives us a clear path to cashflow breakeven in 2004. Our management team and employees will continue their focus on executing each element of our business plan and delivering exciting, innovative services to our growing base of customers," said XM President and CEO Hugh Panero.

The $225 million in new funding is in the form of 10 percent Senior Secured Discount Convertible Notes due in 2009 and a small concurrent common stock sale. Purchasers of the Notes include American Honda Motor Co., Inc.; Hughes Electronics Corporation; The Hearst Corporation; affiliates of Columbia Capital LLC, AEA Investors Inc., Eastbourne Capital Management LLC, Everest Capital Management and BayStar Capital II, L.P.; and other parties. The Notes are convertible into common stock at a price of $3.18 per share. Proceeds will be used for general corporate purposes.

Last week, the XM Board of Directors also voted to add two new members to the Board: R. Steven Hicks, who brings 33 years of experience building successful companies in the radio broadcasting and media industry; and Thomas G. Elliott, Executive Vice President, Automobile Operations of American Honda Motor Co., Inc.
