Acquisition Expands Company's Portfolio of Solutions,
     Technical Capabilities and Customer Footprint in Critical
                          Growth Markets

COLUMBIA, Md., March 5, 2010 (GLOBE NEWSWIRE) -- Integral Systems,
Inc., (Nasdaq:ISYS) announced today that it has acquired privately held
CVG, Incorporated and its subsidiary, Avtec Systems, Inc. (together,
"CVG-Avtec"). The acquisition further expands the reach of Integral
Systems' award winning product line and customer base within the
Department of Defense (DoD). CVG-Avtec, based in Chantilly, VA, has
approximately 100 employees and will be integrated into Integral
Systems' Products Group as Integral Systems SATCOM Solutions.

Integral Systems will pay an aggregate of $34,675,000 in an all cash
transaction or approximately one times the trailing twelve months
revenue of CVG-Avtec. Additional terms of the transaction are
summarized in the current report on Form 8-K filed today by Integral
Systems with the Securities and Exchange Commission. Concurrent with
this acquisition, Integral Systems will obtain a new $55 million
secured credit facility with three syndicate banks led by Bank of
America, N.A. The acquisition will be financed with a combination of
the Company's existing cash available and borrowings under the new line
of credit.

CVG-Avtec provides secure, satellite-based communication solutions to
government and commercial markets. The company offers integrated ground
systems infrastructure solutions for satellite communications, payload
data processing, simulation and testing for military, intelligence,
government, and commercial programs worldwide.

"CVG-Avtec's world-class products and services are immediately
synergistic with our business model," said Paul Casner, President and
CEO of Integral Systems. "With this acquisition we increase our
footprint in the satellite communications (SATCOM) and unmanned aerial
vehicle (UAV) markets and augment our customer offerings for satellite
ground control and processing. In addition, CVG-Avtec's talented
employees -- many of whom have high-level security clearances --
broaden our in-house system engineering and product development
capabilities."

"CVG-Avtec has an outstanding reputation for delivering cutting-edge
solutions in support of its customers," said Stuart Daughtridge,
Executive Vice President of Integral Systems' Products Group. "As
Integral Systems SATCOM Solutions, CVG-Avtec will continue to provide
the technical and subject area expertise to customers that they have
come to expect. In addition, these customers will benefit from having
access to the full range of solutions offered by the existing Integral
Systems family of companies."
