Note to financial results forecast: The above estimates are based on certain assumptions made by the Company's management as of the date hereof. These assumptions are based on management's experience and perception of current conditions, trends, expected future developments and other factors believed to be appropriate in the circumstances. Such estimates are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company and may cause the Company's actual results to differ materially from the above estimates. Although the Company's management believes that these assumptions are reasonable, the Company cannot assure you that the Company's business will develop in accordance with these estimates. Investors are cautioned not to rely on these estimates as it is highly likely that actual results will differ, perhaps materially. These risks include the risk factors detailed in the Company's Securities and Exchange Commission filings, including the Company's Annual Report on Form 10-K for the year ended December 31, 2008 and its subsequent periodic reports on Forms 10-Q and 8-K. Our independent auditors have not compiled or been involved in the preparation of the forecasted financial results for fiscal year 2009. Accordingly, they assume no responsibility for the accuracy or presentation of this information.
