Amended and Restated Credit Agreement due 2011

On March 6, 2009, XM amended and restated (i) the $100,000 Senior Secured Term Loan due 2009, dated as of June 26, 2008, among XM, XM Holdings, the lenders named therein and UBS AG, as administrative agent (the “UBS Term Loan”), and (ii) the $250,000 Senior Secured Revolving Credit Facility due 2009, dated as of May 5, 2006, among XM, XM Holdings, the lenders named therein and JPMorgan Chase Bank, N.A., as administrative agent (the “JPM Revolver” and, together with the UBS Term Loan, the “Previous Facilities”). The Previous Facilities were combined as term loans into the Amended and Restated Credit Agreement, dated as of March 6, 2009, among XM, XM Holdings, the lenders named therein and JPMorgan Chase Bank, N.A., as administrative agent (the “First-Lien Credit Agreement”), and Liberty Media LLC (“Liberty”) purchased $100,000 aggregate principal amount of such loans from the lenders. XM paid a restructuring fee of 2% to the existing lenders under the Previous Facilities.

Loans under the First-Lien Credit Agreement held by existing lenders (the “Tranche A” and the “Tranche B” term loans) mature on May 5, 2010 and the remaining loans purchased by Liberty (the “Tranche C” term loans) mature on May 5, 2011. The Tranche A and the Tranche B term loans are subject to scheduled quarterly amortization payments of $25,000 starting on March 31, 2009 with all remaining amounts ($150,000) due on the maturity date. The Tranche C term loans are subject to a partial amortization of $25,000 on March 31, 2010, with all remaining amounts ($75,000) due on the final maturity date. Pursuant to these maturities and the scheduled amortization payments, of the outstanding principal amount, $100,000 of the $350,000 is due in 2009; $175,000 is due in 2010; and $75,000 is due in 2011. We paid $25,000 on March 31, 2009. The loans bear interest at rates ranging from prime plus 11% to LIBOR (subject to a 3% floor) plus 12%. The current interest rate is 15.00%.

The loans under the First-Lien Credit Agreement are guaranteed by XM Holdings and each of the subsidiary guarantors named therein. The loans are secured by a first lien on substantially all of the assets of XM Holdings, XM and certain subsidiaries named therein. The affirmative covenants, negative covenants and event of default provisions contained in the First-Lien Credit Agreement are substantially similar to those contained in the Previous Facilities, except that (i) XM must maintain cash reserves of $75,000 (without taking into account any proceeds from the Second-Lien Credit Agreement (as defined below)), (ii) SIRIUS must maintain cash reserves of $35,000, (iii) XM Holdings and XM must maintain certain EBITDA levels set forth therein and (iv) an event of default shall occur upon the acceleration of any our material indebtedness or in the event of our voluntary or involuntary bankruptcy.
