International Launch Services (ILS), a world leader in providing mission and launch services to the commercial satellite industry, and SIRIUS XM Radio (NASDAQ:SIRI), America's satellite radio company, today announced a contract for the launch of the XM-5 satellite on an ILS Proton. The satellite is scheduled for launch in 2010. This is the tenth firm award announced by ILS this year.

This will be the 5 th ILS Proton launch for the SIRIUS XM Radio fleet; ILS launched the entire SIRIUS satellite constellation with the most recent being the SIRIUS FM-5 satellite last June. The Proton vehicle is Russia’s premier heavy-lift launcher and is built by Khrunichev Research and Production Space Center, one of the pillars of the Russian space industry and

the majority owner of ILS. Proton has launched over 345 times to date since its maiden flight in 1965.

The 6,000 kg XM-5 satellite will be located at 85 degrees West and will enhance the existing XM satellite fleet, ensuring XM subscribers across North America continue receiving high-quality, digital-music, entertainment and data services. Built on the flight proven Space Systems/Loral 1300 platform, the XM-5 satellite will provide high-power, digital audio radio service (DARS) and will have an end-of-life power capability of nearly 20 kilowatts, making it one of the world's most powerful communications satellites.

“ILS/Proton has launched all of the SIRIUS satellites; that is a strong vote of confidence in the demonstrated abilities of ILS/Proton. We are honored to once again provide critical schedule assurance for the XM-5 mission with an ILS/Proton launch,” said ILS President, Frank McKenna.
