In addition, XM announced that it exercised its early purchase option and has accepted for purchase all of the $489,065,000 aggregate principal amount of its outstanding 11.25% Senior Secured Notes due 2013 (the “11.25% Notes”) tendered and not validly withdrawn prior to 5:00 p.m., New York City time, on October 26, 2010 pursuant to the previously announced tender offer and consent solicitation.

A supplemental indenture and other documents giving effect to the amendments have been executed and delivered. The amendments have eliminated most of the restrictive covenants and certain of the events of default contained in the indenture governing the 11.25% Notes and have released the security for, and guarantees of, the 11.25% Notes.
