Business Update Abe Reichental, CEO

State of Business In the second quarter of 2007, we incurred abnormally high expenses related to the completion of year-end and first quarter audit work We believe that the significant business setbacks and disruptions that we experienced in the course of implementing our strategic initiatives in 2006 have been successfully resolved We remain confident in our overall direction and expect that the key initiatives and investments that we undertook throughout 2006 will provide us with the right platform to achieve our long-term objectives We are gratified with the reduction in inventory and DSO We believe that our growing installed base, coupled with the integration of our new systems with proprietary materials cartridges and our continuum of expert solutions, will continue to improve the profitability of our business as revenue from materials continues to outpace our growth in systems The volatility of our revenue base should decline and its stability should improve as consumables' sales rise as a percentage of the product mix relative to systems We continue to focus on our goals and our efforts to transform our company and the way we do business to establish a strong record of sustained growth and profitability
