Purchases pursuant to the Bid may commence on May 1, 2013 and will terminate on April 30, 2014 or such earlier time as the Bid is completed or terminated at the option of CMG. The price which CMG will pay for any shares purchased will be the prevailing market price of the Common Shares on the TSX at the time of such purchase. The actual number of shares that may be purchased for cancellation and the timing of any such purchases will be at the discretion of CMG, subject to a maximum daily purchase limit of 12,621 shares, which equals 25% of CMG's average daily trading volume for the six months prior to April 26, 2013, other than block purchase exceptions.
