FORWARD LOOKING STATEMENTS : Certain statements contained in this press release may constitute forward-looking statements under Canadian securities legislation. Generally, forward-looking information can be identified by the use of forward-looking terminology such as “expects” or “it is expected”, or variations of such words and phrases or statements that certain actions, events or results “will” occur. This document contains statements about expected or anticipated future events and/or financial results that are forward-looking in nature and as a result, are subject to certain risks and uncertainties, such as general economic, market and business conditions, regulatory processes and actions, technical issues, new legislation, competitive conditions, the uncertainties resulting from potential delays or changes in plans, the occurrence of unexpected events and the company’s ability to execute and implement its future plans. Actual events may differ materially from those projected in the forward-looking statements. When relying on forward-looking statements to make decisions, investors and others should carefully consider the foregoing factors and other uncertainties and should not place undue reliance on such forward-looking statements. The Company does not undertake to update any forward-looking statements, except as may be required by applicable securities laws. For such forward-looking statements, we claim the safe harbour for forward-looking statements within the meaning of the Private Securities Legislation Reform Act of 1995.
