MI Developments announces intention to seek solutions for a prosperous and
successful California horse racing industry

AURORA, ON, May 18 /CNW/ - MI Developments Inc. ("MID") (TSX: MIM.A, MIM.B; NYSE: MIM), on April 30, 2010, went effective with a Plan of Reorganization ("Plan") previously confirmed by the U.S. Bankruptcy Court in respect of the assets of Magna Entertainment Corp. Pursuant to the Plan, MID acquired Santa Anita Park, Golden Gate Fields, Gulfstream Park, The Maryland Jockey Club (Pimlico and Laurel Park), Portland Meadows, XpressBet and AmTote.

MID understands that recent actions taken in respect of the Plan, including actions taken by Santa Anita Park concerning its lease with Oak Tree Racing Association, have been misperceived by the California horse racing industry, including the California Horse Racing Board, the Thoroughbred Owners of California, Breeders' Cup, trainers and breeders in California, other racetracks in California, the California Fairs, and Oak Tree. We believe that our intentions have been misunderstood.

In order to clarify those misunderstandings and misperceptions, MID underscores that it is committed to achieving a viable and sustainable horse racing industry in California and throughout the United States by working collaboratively with all other participants in the industry, including regulators, horsemen, breeders, trainers and other stakeholders.

MID's Vice Chairman and Chief Executive Officer, Dennis Mills, will immediately commence discussions with all participants in the California horse racing industry, including the California Horse Racing Board, the Thoroughbred Owners of California, California breeders and trainers, other racetracks in California, the California Racing Fairs, Breeders' Cup, California legislators, Oak Tree and other stakeholders to come up with both short-term and long-term solutions that will create a prosperous and successful California horse racing industry that will benefit all.

MID regrets any misunderstanding within the horse racing industry. MID, as direct owner of the racing assets recently acquired from Magna Entertainment Corp., and MID's Chairman, Frank Stronach, have been long-time supporters of the horse racing industry. MID looks forward to continuing to work with the horse racing industry and its valued stakeholders in creating and sustaining jointly beneficial solutions to the many issues currently facing the industry.
