These statements can sometimes be identified by our use of forward-looking words such as "may," "will," "anticipate," "believe," "expect," "project," or "intend." All statements, other than statements of historical facts, included in this press release that address activities, events or developments that the Company expects, believes or anticipates will or may occur in the future, are forward-looking statements. These statements are based on certain assumptions and analyses made by the Company in light of its experience and its perception of historical trends, current conditions, expected future developments and other factors it believes are appropriate in the circumstances. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company.

Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.
