Forward Looking Statements

This communication may contain forward-looking statements within the meaning of the federal securities laws, including but not limited to, statements regarding future events including but not limited to the COVID-19 pandemic, developments in the healthcare sector and regulatory framework, the Company’s future performance, as well as management’s expectations, beliefs, intentions, plans, estimates or projections relating to the future (including, without limitation, statements concerning revenue, net income, and earnings per share). Risks and uncertainties exist that may cause the results to differ materially from those set forth in these forward-looking statements. Factors that could cause the anticipated results to differ from those described in the forward-looking statements and additional risks and uncertainties are set forth in Part I, Item A of our most recent Annual Report on Form 10-K and subsequently filed Quarterly Reports on Form 10-Q, including but not limited to: volatility and uncertainty in the global economy, financial markets and on our customers in light of the continuing COVID-19 pandemic, including the potential (i) slowdown or shutdown of preventive and elective medical procedures, (ii) delay in the contracting for additional products and services by our customers and (iii) delay in the sales cycle for new customers; a determination by the jury that the Company has liability in litigation advanced by a former director and shareholder; the volume and timing of systems sales and installations; length of sales cycles and the installation process; the possibility that products will not achieve or sustain market acceptance; seasonal patterns of sales and customer buying behavior; impact of incentive payments under The American Recovery and Reinvestment Act on sales and the ability of the Company to meet continued certification requirements; uncertainties related to the future impact of U.S. tax reform; the impact of governmental and regulatory agency investigations; the

development by competitors of new or superior technologies; the timing, cost and success or failure of new product and service introductions, development and product upgrade releases; undetected errors or bugs in software; product liability; changing economic, political or regulatory influences in the health-care industry; changes in product-pricing policies; availability of third-party products and components; competitive pressures including product offerings, pricing and promotional activities; the Company’s ability or inability to attract and retain qualified personnel; the impact of any proxy contest at the 2021 Annual Meeting of Shareholders; possible regulation of the Company’s software by the U.S. Food and Drug Administration; changes of accounting estimates and assumptions used to prepare the prior periods’ financial statements; disruptions caused by acquisitions of companies, products, or technologies; the extent to which the COVID-19 pandemic and measures taken in response thereto could adversely affect our financial condition and results of operations; and general economic conditions. A significant portion of the Company’s quarterly sales of software product licenses and computer hardware is concluded in the last month of a fiscal quarter, generally with a concentration of such revenues earned in the final ten business days of that month. Due to these and other factors, the Company’s revenues and operating results are very difficult to forecast. A major portion of the Company’s costs and expenses, such as personnel and facilities, are of a fixed nature and, accordingly, a shortfall or decline in quarterly and/or annual revenues typically results in lower profitability or losses. As a result, comparison of the Company’s period-to-period financial performance is not necessarily meaningful and should not be relied upon as an indicator of future performance. These forward-looking statements speak only as of the date hereof. The Company undertakes no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.
