Lockheed Martin Corporation , today announced it has entered into a definitive agreement to acquire ISX Corporation (ISX), a privately owned, California- based provider of military decision systems and other information technology solutions for government customers. Terms of the transaction were not disclosed.

Founded in 1988, ISX provides IT solutions in technology engineering and systems integration; command and control, communications, computers and intelligence; information and knowledge management. Approximately 90 percent of ISX's business comes from the Department of Defense.

"ISX has gained broad recognition for innovation as a research and development leader, to include winning two consecutive awards as DARPA's contractor of the year -- a first for any company," said Bob Stevens, Lockheed Martin Chairman, President and Chief Executive Officer. "This acquisition complements and accelerates our growth in decision systems, distributed collaborative military operations, autonomous systems, and knowledge management."

"ISX has long focused on developing and transitioning innovative information technology that addresses complex warfighting and intelligence challenges," said Scott Fouse, ISX Corporation Chief Executive Officer. "We are very excited to be joining such a high-quality organization as Lockheed Martin, and we look forward to expanding our technologies and methodologies."

Lockheed Martin Advanced Technology Laboratories (ATL), located in Cherry Hill, NJ, will manage the ISX business. ATL is Lockheed Martin's advanced- computing, applied research and development facility. It develops and transitions technologies in autonomy and intelligence, network-centric operations, cognitive computing, information exploitation, and advanced signal processing for Lockheed Martin, DARPA, military services, and service laboratories. The transaction is expected to close in June.

Headquartered in Bethesda, Md., Lockheed Martin employs about 135,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The corporation reported 2005 sales of $37.2 billion.
