NASDAQ Grants Exception

Liberty Media's investment will be funded in two separate phases. Upon completion of the second phase of the Liberty investments, SIRIUS XM will issue Liberty an aggregate of 12.5 million shares of preferred stock convertible into 40% of the common stock of SIRIUS XM. Details regarding the transaction are available in the Current Report on Form 8-K the Company filed with the Securities and Exchange Commission on February 17, 2009.

While the NASDAQ rules generally require shareholder approval prior to the issuance of securities that are convertible into more than 20% of the outstanding shares of a listed company, the Company is relying on an exception in cases when the delay in securing shareholder approval would seriously jeopardize the financial viability of the enterprise. The Company's Audit Committee has approved the use of this exception.
