Forward - Looking Statements This presentation contains forward - looking statements. All statements contained in this presentation other than statements of historical fact, including statements regarding our future results of operations and financial position, our business strategy and plans, and our objectives for future operations, are forward - looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” and similar expressions are intended to identify forward - looking statements. In addition, from time to time, we or our representatives may make forward - looking statements orally or in writing. We have based these forward - looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short - term and long - term business operations and objectives, and financial needs. These forward - looking statements are subject to a number of risks, uncertainties and assumptions, including those described in the “Risk Factors” section of the Company’s preliminary prospectus filed on Form F - 1. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward - looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this prospectus may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward - looking statements. In evaluating these forward - looking statements, you should consider various factors, including: our ability to change the direction of the Company; our ability to keep pace with new technology and changing market needs; and the competitive environment of our business. These and other factors may cause our actual results to differ materially from any forward - looking statement. Forward - looking statements are only predictions. Thus, you should not rely upon forward - looking statements as predictions of future events. The events and circumstances reflected in the forward - looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward - looking statements are reasonable, we cannot guarantee future results, levels of activity, performance, or achievements. Except as required by applicable law, we undertake no duty to update any of these forward - looking statements after the date of this prospectus or to conform these statements to actual results or revised expectations. 3
