Canadian Warrants

The units will separate immediately upon their issuance into their component parts on the basis of one common share and one warrant per unit.

Each warrant will be exercisable into one common share (symbol: MND) for two years from their issuance at 33 cents per common share.

The warrants will be issued in the book-entry system of CDS Clearing and Depository Services Inc. pursuant to the terms of a warrant indenture to be dated Aug. 6, 2010, between the company and Computershare Trust Company of Canada, as warrant agent. The warrants must be purchased, transferred or exercised through participants in the depository service of CDS. The warrant indenture will provide for appropriate adjustments to be made to the warrants upon the occurrence of certain events such as stock splits, consolidations and other forms of capital reorganizations.

The TSX will release a trader note prior to the opening on Aug. 6, 2010, confirming whether or not the closings of the prospectus offering and acquisition have occurred. Should the prospectus offering close but the acquisition not close before the opening on Aug. 6, 2010, the subscription receipts will not be exchanged for units and the trader note will: (i) provide information for the listing and posting for trading of the subscription receipts under the symbol MND.R and Cusip No. 562568 11 3; (ii) state, until further notice, the warrants will be halted from trading at the opening on Aug. 6, 2010; and (iii) state, until further notice, the TSX will not list the common shares underlying the subscription receipts.
