Investment by Liberty Media Corporation and its affiliate, Liberty Radio, LLC

Liberty Media Corporation and its affiliate, Liberty Radio, LLC, have invested an aggregate of $350,000 in the form of loans, are committed to invest an additional $180,000 million in loans, and have received a significant equity interest in us.

Phase One: Sirius Credit Agreement

On February 17, 2009, SIRIUS entered into a Credit Agreement (the “Sirius Credit Agreement”) with Liberty Media Corporation, as administrative agent and collateral agent. The Sirius Credit Agreement provides for a $250,000 term loan and $30,000 of purchase money loans. Concurrently with entering into the Sirius Credit Agreement, SIRIUS borrowed $250,000 under the term loan facility. The proceeds of the term loan were used (i) to repay at maturity our outstanding 2 ¹/2% Convertible Notes due February 17, 2009 and (ii) for general corporate purposes, including related transaction costs.

The loans under the Sirius Credit Agreement bear interest at a rate of 15% per annum. Commencing on March 31, 2010, the loans amortize in quarterly installments equal to: (i) 0.25% of the aggregate principal amount of the loans outstanding on January 1, 2010 and (ii) after December 31, 2011, 25% of the aggregate principal amount of the loans outstanding on January 1, 2012. The loan matures on December 20, 2012. We paid Liberty Media Corporation a structuring fee of $30,000 in connection with the Sirius Credit Agreement. In addition, we will pay a commitment fee of 2.0% per annum on the unused portion of the purchase money loan facility.

The loans under the Sirius Credit Agreement are guaranteed by Satellite CD Radio, Inc. and Sirius Asset Management Company LLC, SIRIUS’ wholly owned subsidiaries. The loans are secured by a lien on substantially all of SIRIUS’ assets. The affirmative covenants, negative covenants and event of default provisions in the Sirius Credit Agreement are substantially similar to those in the Term Credit Agreement, dated as of June 20, 2007, among SIRIUS, the lenders party thereto and Morgan Stanley Senior Funding, Inc., as administrative agent and collateral agent.

Phase One: Investment Agreement

On February 17, 2009, SIRIUS entered into an Investment Agreement (the “Investment Agreement”) with Liberty Radio, LLC (the “Purchaser”), an indirect wholly-owned subsidiary of Liberty Media Corporation. Pursuant to the Investment Agreement, SIRIUS agreed to issue to the Purchaser 12,500,000 shares of convertible preferred stock with a liquidation preference of $0.001 per share in partial consideration for the loan investments described herein.

Upon expiration of the applicable waiting period under the Hart-Scott-Rodino Act, the preferred stock will be convertible into 40% of our outstanding shares of common stock (after giving effect to such conversion). The Purchaser has agreed not to acquire more than 49.9% of our outstanding common stock for three years. Certain of the standstill restrictions will cease to apply after two years.

The rights, preferences and privileges of the preferred stock are set forth in a Certificate of Designations filed with the Secretary of State of the State of Delaware. The holders of the preferred stock are entitled to appoint a proportionate number of our board of directors based on their ownership levels from time to time. The Certificate of Designations also provides that so long as the Purchaser beneficially owns at least half of its initial equity investment, we need the consent of the Purchaser for certain actions, including:

The preferred stock, with respect to dividend rights, ranks on a parity with our common stock, and with respect to rights on liquidation, winding-up and dissolution, rank senior to our common stock. Dividends on the preferred stock are payable, on a non-cumulative basis, as and if declared on our common stock, in cash, on an as-converted basis.

XM Credit Agreement.    On February 17, 2009, XM Satellite Radio Inc. entered into a Credit Agreement (the “XM Credit Agreement”) with Liberty Media Corporation, as administrative agent and collateral agent. The XM Credit Agreement provides for a $150,000 term loan.

On March 6, 2009, XM amended and restated the XM Credit Agreement (the “Second-Lien Credit Agreement”) with Liberty Media Corporation, and simultaneously closed the facility. Pursuant to the Second-Lien Credit Agreement, XM may borrow $150,000 aggregate principal amount of term loans on December 1, 2009. The proceeds of the loans will be used to repay a portion of the 10% Convertible Notes due 2009 of XM Holdings on the stated maturity date thereof. The Second-Lien Credit Agreement matures on March 1, 2011, and bears interest at 15% per annum. XM will pay a commitment fee of 2.0% per annum on the undrawn portion of the Second-Lien Credit Agreement until the date of disbursement of the loans or the termination of the commitments.

The Previous Facilities have been 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 (the “Purchaser”) has 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) will mature on May 5, 2010 and the remaining loans purchased by Liberty (the “Tranche C” term loans) will 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. The Tranche C term loans are subject to a partial amortization of $25,000 on March 31, 2010, with all remaining amounts 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. The loans will bear interest at rates ranging from prime plus 11% to LIBOR (subject to a 3% floor) plus 12%.

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 million (without taking into account any proceeds from the Second-Lien Credit Agreement (as defined above)), (ii) we must maintain cash reserves of $35 million, (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.
