XM TO LAUNCH INNOVATIVE NEW CHANNEL “XMX" ON AUGUST 1

Washington, D.C., July 2, 2007 – XM, the nation’s leading satellite radio service with more than eight million subscribers, today announced the launch of “XMX," an innovative new channel dedicated to XM exclusive music programming. XMX will feature XM’s most popular and critically-acclaimed original music shows all in one place, including “Theme Time Radio Hour with Your Host Bob Dylan," “Ludacris’ Open Mic," “Tom Petty’s Buried Treasure," “In the Swing Seat with Wynton Marsalis," “Quincy Jones’ Off the Charts" and XM’s signature performance/interview series “Artist Confidential," among others. The channel will launch August 1 on XM channel 2.

While new episodes of XM’s original music series will continue to air in their regular timeslots and on their home channels, “XMX" will be uniquely scheduled in a ‘program of the day’ format designed to provide listeners with more opportunities to tune in anytime and listen to episode premieres or catch up on episodes from previous weeks or seasons.

“XMX is the first of its kind, a channel uniquely programmed to meet the needs of our subscribers and how they use the network. As the leader in original programming, our subscribers have been asking for a channel like this and we’re thrilled to bring it to them," said Eric Logan, XM’s executive vice president of programming.

XMX will be heard on XM channel 2, beginning at 12:01 a.m. ET on Wednesday, August 1. More information is available at http://www.xmradio.com/xmx. A complete programming schedule for XMX will be available online later this month.

XM plans additional channel lineup enhancements later this summer, starting with the launch of the Starbucks XM Café channel (channel 45) on August 1. Starbucks XM Café will bring together the very best of the original XM Café and Starbucks Hear Music channels to create the highest-quality coffeehouse music experience – featuring popular programs and live performances from both channels. In addition, later in August, XM will begin broadcasting exclusive sports channels for SEC college sports (channels 199 – 201) and Big 12 college sports (channels 241 and 242), and in September, a news channel dedicated to 24-hour Presidential election coverage called P.O.T.U.S. ’08 (channel 130).
