Mel Karmazin, Chief Executive Officer of SIRIUS XM Radio, said, "We are excited to have closed the second and final phase of our investment agreement with Liberty Media. It is an example of the confidence our lenders and Liberty have in our business model. These transactions resolve all of the uncertainty surrounding the company's and its subsidiaries' debt maturing in 2009. Having addressed our near-term financial obligations, we remain focused on continuing to deliver on all the promise of the merger of SIRIUS and XM -- a more efficient company offering the best programming through new packages to more subscribers."

"We are pleased to have completed the second phase of this investment," said Greg Maffei, president and CEO of Liberty. "This closing allows Liberty to align itself with one of the most exciting companies in media today."

XM Satellite Radio's existing term loan and revolving loan have been rolled into a single term loan facility. As previously agreed, Liberty has purchased $100 million aggregate principal amount from the lenders.

Liberty has committed to loan an additional $150 million to XM Satellite Radio, to be used to repay a portion of the outstanding principal amount of 10% Convertible Notes due December 1, 2009 of XM Satellite Radio Holdings Inc.

Under the existing terms of their agreement, SIRIUS XM has issued Liberty an aggregate of 12.5 million shares of new preferred stock convertible into 40% of the common stock of SIRIUS XM.

J.P. Morgan Securities acted as financial advisor to SIRIUS XM in connection with the transactions. UBS and Lazard Freres & Co. LLC acted as financial advisor to Liberty Media Corporation.
