MI DEVELOPMENTS RECEIVES PROPOSAL FOR ELIMINATION OF DUAL CLASS SHARE STRUCTURE FROM CLASS A SHAREHOLDERS AND ITS CONTROLLING SHAREHOLDER

AURORA, ON, Dec. 22 /PRNewswire-FirstCall/ - MI Developments Inc. ("MID") (TSX: MIM.A, MIM.B; NYSE: MIM) announced that its Board of Directors has received a reorganization proposal providing for the elimination of MID's dual class share structure.  The proposal has been made by holders of its Class A Subordinate Voting Shares representing in excess of 50% of the outstanding Class A Subordinate Voting Shares (the "Initiating Shareholders"), including eight of MID's top ten shareholders.  The proposal is also supported by MID's controlling shareholder (the "Stronach Shareholder"), a company controlled by the Stronach Trust.

The Board of Directors of MID has established a Special Committee of independent directors to review and evaluate the proposal and to make recommendations to the Board.  The Board of Directors will communicate further with MID's shareholders in due course.

The reorganization proposal contemplates the elimination of MID's dual class share structure through:

• The cancellation of all MID Class B Shares held by the Stronach Shareholder in consideration for the transfer to the Stronach Shareholder of MID's horseracing, gaming and real estate development and other assets (and associated liabilities), and US$20 million of working capital (the "Assets"). The Assets include: Santa Anita Park; Golden Gate Fields; MID's joint venture interests in Maryland Jockey Club's real estate and racing assets (Pimlico Race Course, Laurel Park and the Bowie training facility); Gulfstream Park and MID's joint venture interest in the associated retail development; Portland Meadows; horseracing technology assets including Xpressbet® and AmTote; and all properties owned by MID as described under "Real Estate Business - Development Properties" in note 6(a) of the notes to the amended and restated interim consolidated financial statements of MID for the period ended September 30, 2010; and
• Each MID Class A Subordinate Voting Share would be changed into one common share and each MID Class B Share (other than the MID Class B Shares held by the Stronach Shareholder which will be cancelled) would be converted into 1.2 common shares, such that MID would only have one class of common shares.

Upon completion of the reorganization proposal, MID would retain its income producing real estate property business and would be restricted from engaging in or having an interest in, directly or indirectly, any business relating to horse racing or gaming, and the Board of Directors of MID would be comprised of directors elected by shareholders other than the Stronach Shareholder at the shareholders meeting called to consider the reorganization proposal, with the nominees for election to be proposed by the Initiating Shareholders.

The proposal contemplates that if the transfer of the Assets is completed, the transfer would be effective January 1, 2011.  MID would provide funding for the Assets during the period from January 1, 2011 to closing, provided that if the funding requirements exceed on average US$4 million per month, the Stronach Shareholder would reimburse MID for such excess.  The Stronach Shareholder would have a right of first refusal in respect of the Magna International corporate properties in Aurora, Ontario and in Oberwaltersdorf, Austria.  In addition, the proposal contemplates that effective upon closing, the applicable Initiating Shareholders would discontinue the litigation against MID and certain related parties filed with the Ontario Superior Court of Justice and MID would reimburse the Initiating Shareholders for their legal and advisory fees incurred in connection with the transaction and up to US$1 million for other legal and advisory fees, and reimburse the Stronach Shareholder for up to US$1 million of legal and advisory fees incurred in connection with the transaction.

The proposal contemplates that the transaction will be implemented by way of a court-approved plan of arrangement under the Business Corporations Act (Ontario) or other form of transaction agreed to by the parties.  The principal closing conditions of the proposed reorganization include receipt of regulatory approvals, receipt of required MID shareholder approvals, there being no material adverse change in the affairs of MID, MID continuing to operate in the ordinary course and not purchasing any unrelated gaming or horseracing assets, accuracy of MID's disclosure documents, execution of definitive documents by January 31, 2011 and implementation of the transaction by June 30, 2011.

The Initiating Shareholders and the Stronach Shareholder have agreed to vote in favour of the proposed reorganization. ST Acquisition Corp. has advised MID that, as a result of the reorganization proposal, it is suspending its earlier proposal announced on October 1, 2010 to make an offer to purchase any or all of the outstanding Class A Subordinate Voting Shares and Class B Shares of MID for a price of US$13 per share pending completion of the reorganization proposal.

The Initiating Shareholders may terminate their voting agreements if, among other things, definitive documents are not executed by January 31, 2011, the transaction has not been completed by June 30, 2011, the voting agreement has not been signed by a majority of the minority holders of the MID Class B Shares by January 31, 2011, or less than 30% of all outstanding MID Class A Subordinate Voting Shares remain subject to the voting agreement.

MID cautions shareholders and others considering trading in securities of MID that it has only recently received the reorganization proposal, and at this time no decisions or recommendations with respect to the proposal have been made by the Board of Directors of MID.  The proposal is subject to certain material conditions, some of which are beyond MID's control, and there can be no assurance that the transaction contemplated by the reorganization proposal, or any other transaction, will be completed.
