TORONTO, Dec. 13 /PRNewswire-FirstCall/ - IMAX Corporation (Nasdaq:IMAX; TSX:IMX) announced today that it had settled a previously-disclosed litigation with the former owners of United Cinemas International Multiplex B.V. (UCI), an operator of multiplex theatres based in the United Kingdom. The majority of UCI's theatrical exhibition operations, and related entities, were recently sold to a private equity firm in the U.K. The specific terms of the settlement were not disclosed other than that the Company will receive cash payments in the fourth quarter of 2004 and first quarter of 2005.

"We are extremely pleased with this settlement agreement," said IMAX's Co-Chairmen and Co-Chief Executive Officers Richard L. Gelfond and Bradley J. Wechsler. "The cash that we will receive increases our financial flexibility and will help us to continue to execute on our strategic plan of growing the number of IMAX(R) theatres around the world and making IMAX venues the place to see Hollywood's biggest event films."

Added Messrs. Gelfond and Wechsler, "Because of this settlement, the success of The Polar Express: An IMAX 3D Experience, and other factors, we now expect to exceed our previous earnings guidance of $0.23 of net income per share ($0.25 prior to refinancing costs) for 2004."
