Management’s prepared remarks and answers to questions during the presentation referenced in this release, including those concerning the company’s financial results, operational initiatives, future performance expectations, and effects of economic conditions are forward-looking statements and actual results may differ materially from those projected or implied by the forward-looking statements due to a variety of risks and uncertainties. Future performance expectations are predicated upon achievement of various sales and performance targets that may be difficult to meet. Economic conditions are unstable and may cause hospitals and other healthcare providers to curtail HIT system spending. Eclipsys’ cost reduction and other initiatives in response to the challenging economic environment may not be effective, and it is difficult to predict what the company may be able to achieve. Eclipsys sales may be slower than expected due to market conditions, competition, and other factors. Costs may be greater than anticipated due to the potential need to increase spending to ensure performance in accordance with commitments to clients and other factors. 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. The market is highly competitive. Implementation and customization of Eclipsys software is complex and time-consuming. Results depend upon a variety of factors and can vary by client. Each client’s circumstances are unique and may include unforeseen issues that make it more difficult than anticipated to implement or derive benefit from software, implementation or consulting services. The success and timeliness of the company’s services will depend at least in part upon client involvement, which can be difficult to control. Eclipsys is required to meet specified performance standards, and clients can terminate contracts, assess penalties or reduce contract scope under certain circumstances. More information about company risks is available in recent Form 10-K 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.” Eclipsys Corporation and The Outcomes Company are registered trademarks of Eclipsys Corporation.
