                  INTEGRAL SYSTEMS ANNOUNCES FINANCIAL RESULTS
                         FOR THE SECOND QUARTER OF 2003

               Quarterly Revenue and Net Income are Historic Highs

Lanham, Md., May 12, 2003 -- Integral Systems, Inc. (NASDAQ: ISYS) today
reported financial results for the second quarter of fiscal 2003. Revenues for
the quarter were $20 million, up from $10.6 million in the second quarter of
fiscal 2002--an increase of approximately 89%, and a new Company record.
Operating income also rose to $2.3 million for the quarter, versus $152,000 in
the second quarter of fiscal 2002--a fifteen fold increase.

Net income increased to $1.5 million in the second quarter of fiscal 2003 from
$434,000 in the second quarter of fiscal 2002, an increase of 246% and also a
new Company record. Further, net income from the second quarter last year was
boosted by a gain of approximately $390,000 on the sale of marketable equity
securities which did not recur during the current quarter, making the current
quarter to quarter increase in net operating income that much more dramatic. On
a fully diluted per share basis, net income tripled to $.15 during the second
quarter of fiscal 2003 from $.05 during the second quarter of fiscal 2002.

"While we are pleased with our second quarter revenue totals, we are even more
gratified to see the improvements in operating income and net income," commented
Steven R. Chamberlain, Chairman and Chief Executive Officer. "Although our SAT
and Newpoint subsidiaries have yet to reach break-even, the results from the
Company's core command and control business plus operating income from our newly
acquired subsidiary, RT Logic, have handsomely offset the losses from the two
losing subsidiaries."

"Despite the losses at SAT and Newpoint, we are seeing operating improvements
and efficiencies for both entities each consecutive quarter. Our focus continues
to be long term in nature and we intend to invest in these businesses for the
foreseeable future. We believe that once the commercial satellite market in
general turns around both SAT and Newpoint will begin to generate positive
operating results," Chamberlain said.

Operating results for the three months ended March 31, 2003 include full quarter
results for Newpoint and RT Logic. The Company did not own RT Logic in the
second quarter of the prior year while Newpoint was only owned for two months of
the prior year's second quarter.

For the six months ended March 31, 2003 revenues were $39.5 million compared to
$20.8 million for the six months ended March 31, 2002 - an increase of $18.7
million or 90%. For the current six-month

                                     -more-



period, operating income was $3.6 million compared to $810,000 for the same
period last year, while net income increased to $2.3 million from $1.1 million,
an increase of approximately $1.3 million. On a fully diluted per share basis,
net income increased to $.24 during the six months ended March 31, 2003 from
$.11 during the first half of fiscal 2002.

 "Currently we are on target to meet or beat our previously announced guidance
for the full fiscal year," remarked Chamberlain. "Through the first half of the
current fiscal year, we have already recorded 78% of our full fiscal 2002
revenue and more importantly 89% of all the net income posted in fiscal 2002.
One should also remember that the net income figure for fiscal 2002 included
gains of approximately $1.1 million on marketable security sales that have not
recurred this year," stated Chamberlain.

Mr. Chamberlain will host a conference call Wednesday, May 14, 2003 at 11:00
a.m. Eastern Time (ET). Chamberlain will discuss the earnings release and other
Company prospects. To participate or listen to the call, dial 800-558-9407. A
