DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

This annual report contains forward-looking statements that reflect our current expectations and views of future events, all of which are subject to risks and uncertainties. Forward-looking statements give our current expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current facts. You can find many (but not all) of these statements by the use of words such as “approximates,” “believes,” “hopes,” “expects,” “anticipates,” “estimates,” “projects,” “intends,” “plans,” “will,” “would,” “should,” “could,” “may” or other similar expressions in this annual report. These statements are likely to address our growth strategy, financial results and product and development programs. You must carefully consider any such statements and should understand that many factors could cause actual results to differ from our forward-looking statements. These factors may include inaccurate assumptions and a broad variety of other risks and uncertainties, including some that are known and some that are not. No forward-looking statement can be guaranteed and actual future results may vary materially. Factors that could cause actual results to differ from those discussed in the forward-looking statements include, but are not limited to:

We base our forward-looking statements on our management’s beliefs and assumptions based on information available to our management at the time the statements are made. We caution you that actual outcomes and results may, and are likely to, differ materially from what is expressed, implied or forecast by our forward-looking statements. Accordingly, you should be careful about relying on any forward-looking statements. Except as required under the federal securities laws, we do not have any intention or obligation to update publicly any forward-looking statements after the distribution of this annual report, whether as a result of new information, future events, changes in assumptions, or otherwise.
