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.
