Yesterday's Announcement We filed for an extension of time to file our first quarter Form 10-Q We have delayed releasing our first-quarter 2007 operating results until we finish the 10-Q We wanted to share with you preliminary results for the first quarter of 2007 There can be no assurance that the final results that we report will be within the ranges set forth today

First Quarter 2007 Expectations We believe that: Revenue for the first quarter should be in the range of $36 to $37 million Revenue for materials is expected to continue its double-digit pace of growth Gross profit should be in the range of $15.5 million to $16.5 million for the first quarter

We believe that: Operating loss for the first quarter should be in the range of $1 million to $2 million Net loss available to the common stockholders should be in the range of $1.5 to $2.5 million for the first quarter of 2007 Unrestricted cash on hand should be approximately $7 million, primarily reflecting borrowings under our Bank credit facility. We expect to repay or refinance those bank borrowings when they become due. First Quarter 2007 Expectations

State of Business We believe that the significant business setbacks and disruptions that we experienced in the course of implementing our strategic initiatives in 2006 are now largely behind us We are gratified with the progress we are making In the first quarter of 2007, we continued to incur abnormally high expenses related to the restatement and year-end audit Strong demand for our materials suggests that the demand for our products remains strong Our growing installed base, coupled with the integration of our new systems with proprietary materials' cartridges and our continuum of expert solutions, should improve the profitability of our business as revenue from materials continues to outpace the growth in systems

State of Business (continued) The stability of our revenue base should improve as consumables' sales rise as a percentage of the product mix relative to systems We are committed to completing our remediation efforts and to having state-of-the-art controls, procedures and processes We continue undeterred 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

Out of respect for other conference call participants, please ask one question and then return to the queue to ask additional questions. Because of the preliminary nature of our first- quarter 2007 results, we are not in a position today to comment further on them. All questions must be directed through the teleconference portion of this call. Questions via the web will not be accepted. Question & Answer Session
