TeleCommunication Systems Completes Acquisition
of Networks In Motion

TCS to Host Conference Call to Discuss the Acquisition Tomorrow Wednesday, December 16
at 9:30 A.M. ET

ANNAPOLIS, MD— December 15, 2009 — TeleCommunication Systems, Inc. (TCS) (NASDAQ:TSYS), a leading provider of mission-critical wireless communications, today announced the successful completion of its acquisition of Networks In Motion, Inc., (NIM) a privately held provider of wireless navigation solutions for GPS-enabled mobile phones.

Pursuant to the merger agreement, TCS issued former Networks In Motion shareholders approximately $110 million in cash, $40 million in promissory notes, and approximately 2.2 million shares of TCS common stock valued at $20 million based on the volume weighted average stock price for 10 days prior to close. The promissory notes bear simple interest at 6% and are due in three installments: $30 million on the 12 month anniversary of the closing,$5 million on the 18 month anniversary of the closing, and $5 million on the 24 month anniversary of the closing, subject to escrow adjustments.

The U.S. consumer Location-Based Services (LBS) space is one of the most dynamic areas of wireless applications and continues to transform the mobile experience. In a January 2009 Frost & Sullivan report on LBS companies, TCS was shown to offer the most complete LBS solution. In May 2009, TCS acquired the LBS assets of the company with the next most complete LBS solution, LocationLogic, adding two leading location-based applications and additional depth to its carrier LBS infrastructure “stack.” TCS has had wireless traffic and points-of-interest applications since 2004. The acquisition of Networks In Motion adds a Tier 1, market leading navigation business.

“The addition of Networks In Motion strengthens TCS’s market position in three significant ways,” said Maurice B. Tosé, TCS chairman and CEO. “First, it substantially enhances our portfolio of Tier 1 location based wireless applications, with market-leading navigation technology that shares the 99.999% reliability standard of other TCS solutions. Second, it deepens our longstanding relationships with three of the largest North American carriers and adds an internationally recognized navigation application to our global LBS applications portfolio. And finally, the acquisition adds 13 patents and 44 applications that are complementary to our existing patent portfolio of 94 patents issued in the U.S. and abroad, and more than 260 patent applications pending — reinforcing our position as a location technology leader. Overall, we expect this acquisition to enhance our LBS leadership in an industry which is at the early stages of what is widely viewed as a long term, high growth market, better enabling us to support carriers in monetizing LBS as we have with text messaging for more than a decade.”

The acquisition also further shifts the company’s revenue mix from an historical 50% services/50% systems to an expected 2010 revenue that is 65% services/35% systems. Substantially all of Networks In Motion’s revenue is recurring services revenue derived from subscriptions to its full-featured navigation applications, providing high visibility of future revenues. Based on contracts in place at the time of acquisition, TCS expects the NIM business to add $65 to $75 million to TCS’s 2010 commercial services revenue and $21 to $24 million to EBITDA. Networks In Motion has about 3.5 million subscribers to its applications, and about 200 employees. The transaction is expected to be accretive to net income by the end of 2010.

TCS announced its agreement to acquire NIM on December 1, 2009. TCS may incur one-time acquisition- related charges in this quarter to account for expenses associated with the transaction.

Raymond James & Associates served as financial advisor to TCS in this transaction. Networks In Motion was advised by Jefferies & Co.
