Business Editors/High Tech Writers

FAIRFAX, Va.--(BUSINESS WIRE)--May 24, 2001

BTG, Inc. (Nasdaq: BTGI), an information systems and technical services company, announced that it is a subcontractor to Anteon Corporation on a firm fixed-price contract to provide battle simulation services to the U.S. Army.

The contract is valued at $47 million over nine years, assuming all options are exercised, with revenue to BTG estimated at $6 million over the term.

The contract was issued by the Fort Hood Contracting Command and the work will be performed at the Army's III Corps Battle Simulation Centers at Fort Hood, Texas, Fort Carson, Colorado, Fort Riley, Kansas, and at various international locations. Anteon will support the full spectrum of the Army's computer-based simulation models at Fort Hood. BTG will operate the Fort Riley Battle Simulation Center, which offers a full range of simulation activities and supports the U.S. Army Simulation, Training, and Instrumentation Command (STRICOM) with database management, system administration, and simulation technician/instructors. The Centers train officers, non-commissioned officers, warrant officers, and unit personnel on battle simulations, including the Corps Battle Simulation (CBS), Brigade and Battle Simulation (BBS), JANUS, SPECTRUM, and a range of variants to these simulations.

BTG Group Vice President Kevin Wilshere, General Manager of the company's Logistics, Engineering and Training business unit, said the program is critical in the development of training simulations for U.S. military forces. It combines live and virtual simulations to prepare soldiers, intelligence teams, and battle units for the 21st century.

Wilshere said highlights of BTG's work with U.S. military forces include:

--Development of operational tools applicable to the development of critical systems that have been used Army-wide to improve combat capabilities.

--Porting of legacy simulation systems to PC-based applications at all levels of command in the Army to enhance Command and Staff training.

--Development of customized databases for simulation sites that allow commanders to tailor their training exercises to fit their warfighting needs.

--Development of a book of "workarounds" for the JANUS and BBS systems, which provides for greater functionality and reduces down time during training exercises.

--Building of a top secret lab with fiber optic interface for the Department of Defense that linked nine development agents into a single simulation system that allowed every customer involved to gain access to sensitive information and to fully integrate joint training.

--Application of the company's experience in Post Deployment Software Support (PDSS) to improve legacy systems that must fill the training gap while new systems are under development.

Wilshere said BTG provides a variety of services in the modeling and simulation area, including engineering, logistics, systems integration, and life cycle software engineering support. For the U.S. Army Simulation Training and Instrumentation Command (STRICOM), BTG supports Battle Simulation Centers at 11 sites throughout the United States, the Close Combat Tactical Trainer program, the Corps Battle Simulation system, the Brigade and Battle Simulation system, and the JANUS system. BTG also supports the National Security Agency on the Joint Simulation System Signals Intelligence Simulation (J-SIGSIM) for the next generation of joint military training simulations. The company also provides Life Cycle Contractor Support for the Army's Communications-Electronics (CECOM) Software Engineering Center.

In addition to Modeling and Simulation, BTG's expert practice areas include Integrated Logistics Support, Information Management, Enterprise Support Services and Network Management, Technology in Schools, E-Commerce, Geographic Information Systems, Mobile Computing, and Client Care Services.
