TeleCommunication Systems Named Sole Awardee on $315 Million Contract to Deliver U.S. Navy Satellite Communications Infrastructu

   TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a world leader in highly reliable and secure mobile communication technology, today announced that it has been named as the sole awardee on an indefinite-delivery/indefinite-quantity (IDIQ) contract for Military Sealift Command's Next Generation Wideband commercial satellite communications infrastructure and service. The contract -- with a $315 million potential value and a guaranteed first-year minimum of $5 million -- will replace the current MSC Afloat Bandwidth Efficient Satellite Transport commercial satellite communications infrastructure. The period of performance is four years plus four one-year option periods, November 3, 2010 through November 2, 2018. The Defense Information Systems Agency (DISA), Defense Information Technology Contracting Organization (DITCO), is managing the contract activity and selected TCS from a full and open competitive action.

TCS will provide the U.S. Navy's Military Sealift Command (MSC) Next Generation Wideband communications with integrated systems and services for a highly secure, turnkey solution through a proven, commercial off-the-shelf (COTS) antenna system and comprehensive wideband satellite coverage. TCS and its supporting partners will provide MSC with overall contract program management; bandwidth and managed services; engineering and integration expertise; information assurance management; and installation, operation and maintenance services.

"TCS is pleased to be awarded the Military Sealift Command's Next Generation Wideband contract," said Michael Bristol, senior vice president and general manager of government solutions at TCS. "This solution is in direct alignment with TCS' core competencies, as it requires secure, cost-effective, end-to-end IP communications pathways linking more than seventy globally deployed ships with MSC network operation centers. We are fully committed to this opportunity as the Navy's innovative partner to bring proven off-the-shelf technology and reliable total communications-on-the-move solutions in support of their maritime missions."

The U.S. Navy's Military Sealift Command is the premier provider of ocean transportation for the Department of Defense. Originally named Military Sea Transportation Service, MSC was created to consolidate the Department of Defense's sealift assets and ensure that the U.S. military would be able to rapidly deploy troops, equipment and supplies by sea to any location in the world. The MSC mission has evolved subtly over time -- for instance moving away from troop transport and moving toward combat logistics support and humanitarian relief. Through all this, MSC has proven her value again and again from the Korean War to the Vietnam War to the events following the September 11, 2001, terrorists attacks on the United States to tsunami relief efforts in Indonesian and hurricane relief on the Gulf Coast of the United States.

TCS has established a proven track record for more than two decades as a trusted provider of communication technology solutions to solve the government's toughest technical challenges, under conditions that demand the highest level of reliability, availability and security. To ensure mission continuity, TCS offers a family of deployable communications solutions, SwiftLink® and complete end-to-end managed services for converged (IP-based) voice, video and data solutions to organizations requiring seamless, highly secure connectivity between fixed sites and remote operations.
