Item 5.  Other Events.

         Today we announced a new agreement with DaimlerChrysler Corporation.
Beginning with 2005 model year vehicles, DaimlerChrysler will bundle a one-year
subscription to our service in all of its vehicles that contain a
factory-installed Sirius radio. DaimlerChrysler has agreed to use commercially
reasonable efforts to produce and distribute an aggregate of 550,000 such
bundled vehicles by June 30, 2006. We will receive from Chrysler our standard
one-year subscription fee for each bundled subscription. We have agreed to
reimburse DaimlerChrysler for the costs of factory-installed Sirius radios and
to pay incentives to DaimlerChrysler upon the achievement of agreed upon volume
thresholds. DaimlerChrysler will continue to offer Sirius radios as a
dealer-installed option in the majority of its remaining vehicles.

         We will issue DaimlerChryler AG warrants to purchase an aggregate of up
to 21.5 million shares of our common stock at an exercise price of $1.04 per
share (a valuation at which we issued warrants in connection with our
recapitalization in March 2003). These warrants vest based on the achievement of
various performance milestones, including the volume thresholds contained in our
agreement with DaimlerChrysler Corporation. These warrants replace the warrants
issued to DaimlerChrysler AG in October 2002.
