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.
