SIRIUS unleashed a national print and retail advertising campaign today, which sets forth the "SIRIUS Guarantee" in national and metropolitan publications. The guarantee says clearly that no SIRIUS radios will become obsolete as a result of a merger with XM. SIRIUS has millions of radios in the market, including many that are built into the vehicles manufactured by its automakers.

    * 100% commercial-free music

    * The best sports line-up including the NFL, NASCAR, NBA and college
