Computer Modelling Group Receives Acceptance for Normal Course Issuer Bid

CALGARY, ALBERTA--(Marketwired - May 21, 2015) - Computer Modelling Group Ltd. ("CMG" or the "Company") (TSX:CMG) today announced that the Toronto Stock Exchange ("TSX") has accepted CMG's Notice of Intention to make a Normal Course Issuer Bid (the "Bid") through the facilities of the TSX. The Bid will permit the Company to purchase for cancellation up to 7,446,987 Common Shares of the Company, representing approximately 10% of CMG's public float, which was 74,469,870 at May 12, 2015. As at May 12, 2015 CMG's issued and outstanding shares were 78,543,457 Common Shares.

Purchases pursuant to the Bid may commence on May 25, 2015 and will terminate on May 24, 2016 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 28,063 shares, which equals 25% of CMG's average daily trading volume for the six months prior to May 1, 2015, other than block purchase exceptions. The average daily trading volume for such period was 112,252.

In addition, the purchase of shares by the Company may increase liquidity of the Common Shares.
