Safe Harbor Statement

2. Safe Harbor Statement The attached materials and management’s prepared remarks include forward-looking statements, and management may make additional forward-looking statements in response to questions. These materials may include, but are not limited to, statements concerning our anticipated performance, including revenue, margin, cash flow, balance sheet and profit expectations; development and implementation of our software; duration, size, scope and revenue expectations associated with client contracts; benefits provided by Eclipsys software, outsourcing and consulting services; business mix; sales and growth in our client base; market opportunities; industry conditions; and our accounting, including its effects and potential changes in accounting. Actual results might differ materially from the results projected due to a number of risks and uncertainties. Software development may take longer and cost more than expected, and incorporation of anticipated features and functionality may be delayed, due to various factors including programming and integration challenges and resource constraints. We may change our product strategy in response to client requirements, market factors, resource availability, and other factors. Implementation of some of our software is complex and time consuming. Results depend upon a variety of factors and can vary by client. Each client’s circumstances may include unforeseen issues that make it more difficult or costly than anticipated to implement or derive benefit from software, outsourcing or consulting services. The success and timeliness of our services often depends at least in part upon client involvement, which can be difficult to control. We are required to meet specified performance standards, and contracts can be terminated or their scope reduced under certain circumstances. Competition is vigorous, and competitors may develop more compelling offerings or offer more aggressive pricing. New business is not assured and existing clients may migrate to competing offerings. Financial performance targets might not be achieved due to various risks, including slower-than-expected business development or new account implementation, or higher-than-expected costs to develop products, meet service commitments or sign new contracts. Our cash consumption may exceed expected levels if profitability does not meet expectations or strategic opportunities require cash investments. More information about Eclipsys’ risks is available in Eclipsys’ recent Form 10-Q and other filings made by Eclipsys from time to time with the Securities and Exchange Commission. Special attention is directed to the portions of those documents entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
