CRTC Approvals Obtained in Connection With Alliance Atlantis' Plan of Arrangement

Mr. James Macdonald appointed to act as trustee

TORONTO, May 25 /PRNewswire-FirstCall/ -- Alliance Atlantis Communications Inc. ("Alliance Atlantis") and CanWest Global Communications Corp. ("CanWest") today announced that approvals had been obtained from the Canadian Radio-television and Telecommunications Commission ("CRTC") in respect of the Plan of Arrangement pursuant to which AA Acquisition Corp. (formerly 6681859 Canada Inc.) would acquire all of the outstanding shares of Alliance Atlantis for $53.00 cash per share.

Alliance Atlantis owns (directly or indirectly) the securities of certain entities which are regulated by the CRTC. In connection with the completion of the Plan of Arrangement, those securities will be deposited with a trustee pending the CRTC's decision regarding the acquisition of those regulated entities by AA Acquisition Corp. The CRTC has now approved the trust arrangements with respect to those regulated entities, including the appointment of Mr. James Macdonald to act as trustee. Approval of the trust arrangements by the CRTC is a condition of completion of the Plan of Arrangement, and this condition has now been satisfied.

After completion of the Plan of Arrangement, it is intended that there will be a reorganization of the various business units and assets of Alliance Atlantis. The CRTC has now also approved those steps in the reorganization which includes the entities that are regulated by the CRTC being placed in the approved trust. Approval of the reorganization by the CRTC is also a condition of the Arrangement, and this condition has now been satisfied.

While no other CRTC approvals are required as conditions of the Plan of Arrangement, the acquisition of the regulated entities by AA Acquisition Corp. remains subject to the CRTC's approval.

"We are very pleased that these approvals have been obtained which satisfy certain conditions pertaining to the acquisition," said Leonard Asper, President and Chief Executive Officer of CanWest. "This is another important step in the transaction process. All material regulatory approvals required in connection with the broadcasting operations that are part of the Plan of Arrangement have now been obtained."

"Jim Macdonald is a highly experienced and well-respected member of the Canadian broadcasting industry," said Phyllis Yaffe, Chief Executive Officer of Alliance Atlantis. "Jim's long-standing commitment to the broadcasting sector makes him an ideal candidate for this important role and I look forward to working with him in the weeks and months ahead."
