SIRIUS Canada Inc. announced that it has
exceeded 750,000 paying subscribers, adding more than 250,000 subscribers in
the 8 months since October 2007. The last 8 months were the company’s
strongest period of subscriber growth since inception and SIRIUS expects the
growth to continue through the busy Father’s Day sales period and beyond.

“SIRIUS has experienced a surge of growth in the past 8 months from both
the automotive and retail channel and its subscriber base is now in excess of
750,000 paying customers,” said Mark Redmond, President and CEO, SIRIUS Canada
Inc. “The last 8 months were the strongest period of subscriber growth since
launch and our success to-date has surpassed the expectations of the company’s
management and shareholders. We’d like to thank SIRIUS’ employees, subscribers
as well as our automotive and retail partners for helping achieve this
important milestone.”

SIRIUS also announced that later this month it will increase its
programming line-up to 120 full time channels, adding a range of sports and
talk programming, and 100% commercial-free music channels.

“With the best coverage and content and now with 120 channels, SIRIUS is
the leading satellite radio brand in the country and will continue to compete
aggressively to become an even larger part of Canadians’ entertainment-mix.
SIRIUS is proud to be Canada’s number one choice for satellite radio with
unique content not available on any other platform,” said Redmond.

Since launch, SIRIUS Satellite Radio has been the fastest growing
satellite radio company in Canada with the most subscribers and the brand most
selected by consumers. According to The NPD Group, SIRIUS captured 73% market
share of satellite radios sold at retail during April 2008 and more than 75%
market share throughout 2007.
