TorontoStock Exchange Symbol: XSR

TORONTO, Jan. 18 /PRNewswire/ - Canadian Satellite Radio Holdings Inc. (the "Company"), parent company of XM Canada, announced today that it has mailed to its shareholders a notice of meeting, a management information circular (the "Circular") and other materials for its annual and special meeting of shareholders (the "Meeting") to be held on Thursday, February 17, 2011 at 2:00 p.m. (Toronto time) at the Ivey ING Director Leadership Centre, Ground Floor, 130 King Street West, Toronto, Ontario, M5X 1A9.

At the Meeting, disinterested shareholders will be asked to approve, among other things, the following special business matters (the "Special Resolutions"), all as more particularly described in the Circular, in connection with the proposed merger (the "Combination Transaction") of the Company and Sirius Canada Inc. ("Sirius"):

• ordinary resolutions approving the issuance from treasury of shares representing a 58.0% equity interest in the Company (on a partially diluted basis) immediately following closing of the Combination Transaction;
• ordinary resolutions approving the appointment of a new slate of directors, to be conditional on, and effective as of the closing of the Combination Transaction; and
• special resolutions approving certain amendments to the Company's articles, to be conditional on, and effective as of the closing of the Combination Transaction.

The Circular describes, among other things, the particulars of the Combination Transaction, additional details regarding the Special Resolutions and the manner in which shareholders may vote at the Meeting. The Company's board of directors, based on the unanimous recommendation of a committee of independent directors, has recommended that shareholders support the Combination Transaction by voting in favour of each of the Special Resolutions at the Meeting, Two directors of the Company abstained from voting on the board's recommendation due to a potential conflict of interest resulting from their respective relationships with Sirius XM Radio Inc., which currently holds an approximate 19.9% voting interest (approximately 49.9% equity interest) of Sirius and an indirect 10.5% voting interest (21.5% equity interest) of the Company. CSRI Inc., an entity controlled by John I. Bitove, the Executive Chairman of the Company and which currently holds a 77.0% voting interest in the Company on a non-diluted basis, has entered into a voting support agreement with Sirius and its shareholders pursuant to which it has committed to vote all of its shares in favour of the Special Resolutions at the Meeting, subject to certain terms and conditions. Copies of the Circular and other meeting materials are available on SEDAR at www.sedar.com. Shareholders are encouraged to read the Circular and other meeting materials in their entirety and to vote.

The Company's board of directors fixed the close of business on January 10, 2011, as the record date for the determination of shareholders entitled to receive notice of and to vote at the Meeting and any adjournment or postponement thereof. No shareholders becoming shareholders of record after that time will be entitled to vote at the Meeting, or any adjournment or postponement thereof. In addition to disinterested shareholder approval, completion of the Combination Transaction is subject to certain other conditions including regulatory review and approvals. It is currently expected that the Combination Transaction will be completed during the third quarter of the Company's 2011 fiscal year.
