TeleCommunication Systems Executes Definitive Agreement
to Acquire Networks In Motion, Inc.

ANNAPOLIS, MD — December 1, 2009— TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a leading provider of mission-critical wireless communications, today announced that it has entered into a definitive merger agreement to acquire Networks In Motion, Inc., a privately held provider of wireless navigation solutions for GPS-enabled mobile phones headquartered in Aliso Viejo, California, for an aggregate of $170 million. The merger consideration will be paid in a combination of cash, TCS common stock and promissory notes. Networks in Motion’s Board of Directors has unanimously adopted the merger agreement and recommended its approval by Networks in Motion’s stockholders.

The acquisition accelerates TCS’ position in enabling mobile operators to offer enhanced location-based data services. “Location-based services are experiencing substantial growth and we believe that this is the right time to invest to strengthen our participation in this space,” said Maurice B. Tosé, chief executive officer of TCS. “We believe the combination of Networks in Motion applications with our current offerings of carrier infrastructure and applications for location-based services will enhance our value proposition for this exciting market.”

“TCS provides an ideal opportunity for us to achieve our goals of leadership in location-based services on a faster and much larger scale,” said Doug Antone, chief executive officer of Networks in Motion. We look forward to becoming an integral part of the TCS family.”

The transaction is subject to the terms and conditions of the merger agreement, the approval of Network in Motion’s stockholders, and customary regulatory clearance and other closing conditions. The transaction is expected to close in December 2009. Following the closing of the transaction, TCS will provide additional information about the transaction and will host an investor conference call.

This announcement is neither an offer to sell nor a solicitation of an offer to buy any of securities of TCS or Networks in Motion and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful.

The shares of TCS common stock, both series of notes and the shares of TCS common stock which may be issued in lieu of payment in cash for one of the series of notes have not been registered under the Securities Act of 1933, as amended, or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.
