This presentation has been prepared to assist interested parties in making their own evaluation of the Company and does not propose to contain all of the information that may be relevant. In all cases, interested parties should conduct their own investigation and analysis of the Company and the data set forth in the presentation and any other information provided by or on behalf of the Company. This presentation does not constitute an offer to sell, nor a solicitation of an offer to buy, any securities of the Company by any person in any jurisdiction in which it is unlawful for such person to make such an offering or solicitation. Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of the securities of the Company or passed upon the accuracy or adequacy of this presentation.

Except as otherwise indicated, this presentation speaks as of the date hereof. The delivery of this presentation shall not, under any circumstances, create any implication that there has been no change in the affairs of the Company after the date hereof.

The Company cannot guarantee the accuracy of such information and has not independently verified such information.

This presentation contains forward-looking statements within the meaning of the federal securities laws. These forward-looking statements can be identified by the use of forward-looking terminology, including the terms "believe," "estimate," "project," "anticipate," "expect," "seek," "predict," "continue," "possible," "intend," "may," "might," "will," "could," would" or "should" or, in each case, their negative, or other variations or comparable terminology. These forward-looking statements include all matters that are not historical facts. They appear in a number of places throughout this presentation and include statements regarding our intentions, beliefs or current expectations concerning, among other things, the performance of our products in the marketplace, the current technological, network, and communication platforms our products operate on and with; our ability to stay current and competitive in our research and development efforts; our ability to protect and enforce our intellectual property rights, the success of our commercialization objectives, and our customer marketing and sales initiatives. We derive many of our forward-looking statements from our operating budgets and forecasts, which are based upon many detailed assumptions. While we believe that our assumptions are reasonable, we caution that it is very difficult to predict the impact of known factors, and, of course, it is impossible for us to anticipate all factors that could affect our actual results. Forward-looking statements should not be read as a guarantee of future performance or results and may not be accurate indications of when such performance or results will be achieved. In light of these risks and uncertainties, the forward-looking events and circumstances discussed in this presentation may not occur and actual results could differ materially from those anticipated or implied in the forward-looking statements. A number of important factors could cause our actual results to differ materially from those indicated in these forward-looking statements, including risks and uncertainties related to product performance, rapidly changing technologies, and the success of our sales and marketing efforts, as well as those set forth in the Company's filings with the Securities and Exchange Commission under the heading "Risk Factors."
