This news release may contain forward-looking statements within the meaning of
the federal securities laws. Statements regarding future events, developments,
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 and net income), are
forward-looking statements within the meaning of these laws and involve a number
of risks and uncertainties. Moreover, these forward-looking statements are
subject to a number of risks and uncertainties, some of which are outlined
below. As a result, actual results may vary materially from those anticipated by
the forward-looking statements. Among the important factors that could cause
actual results to differ materially from those indicated by such forward-looking
statements are: 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; the
timing, cost and success or failure of new product and service introductions,
development and product upgrade releases; undetected errors or bugs in software;
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; possible regulation of the Company's
software by the U.S. Food and Drug Administration; uncertainties concerning
threatened, pending and new litigation against the Company including related
professional services fees; uncertainties concerning the amount and timing of
professional fees incurred by the Company generally; changes of accounting
estimates and assumptions used to prepare the prior periods' financial
statements; general economic conditions; and the risk factors detailed from time
to time in Quality Systems' periodic reports and registration statements filed
with the Securities and Exchange Commission. A significant portion of the
Company's quarterly sales of software product licenses and computer hardware is
concluded in the last month of the 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.
The Company undertakes no obligation to publicly update any forward-looking
statements, whether as a result of new information, future events or otherwise.
