                      INTEGRAL SYSTEMS TO ACQUIRE RT LOGIC

Lanham, Md., September 3, 2002 -- Integral Systems, Inc. (NASDAQ: ISYS) today
announced the signing of a Letter of Intent proposing to acquire Real Time
Logic, Inc. (RT Logic) of Colorado Springs, Colorado. RT Logic is a privately
held company that specializes in the real time satellite, ground, test, and
range computing markets. RT Logic provides software driver products,
hardware/firmware-based interface systems, engineering services, integrated
development platforms, and complete turnkey solutions.

Under the terms of the proposal, Integral Systems will pay RT Logic shareholders
consideration nominally valued at $36.5 million, of which approximately $10.0
million will be in the form of a future earnout based on RT Logic pretax income
over the next three to four fiscal years. Payments are expected to be made with
50% cash and 50% Integral common stock. The acquisition of RT Logic is subject
to the negotiation and execution of a definitive purchase agreement and is
expected to close on or about October 1, 2002.

For the fiscal year ended March 31, 2002, RT Logic recorded $12.6 million in
revenue and earned $1.7 million of net income (audited). Steven R. Chamberlain,
Integral's Chairman and CEO, commented, "The acquisition of RT Logic is a
natural fit for us and will instantly expand our product offerings to our
Government client base. We intend to leave RT Logic as a standalone operating
entity, and are excited about the possibilities and opportunities that this
acquisition will afford us. We expect RT Logic to be immediately accretive to
earnings as the acquisition should add between $.08 and $.10 to EPS in FY03,"
added Chamberlain.

Mark McMillen, Chairman and Chief Executive Officer of RT Logic commented that,
"The industry name recognition of Integral Systems coupled with Integral's
financial muscle should help RT Logic to accelerate its revenue and profit
growth. The employees at RT Logic and myself are eager to begin working together
on joint product and marketing efforts."
