TeleCommunication Systems, Inc. Named to Everything Channels' VARBusiness 500 List for Third Consecutive Year

ANNAPOLIS, MD (NASDAQ: TSYS), a leading provider of mission-critical wireless communications, today announced that it has been recognized by Everything Channel's VARBusiness magazine as one of North America's top technology integrators. TCS placed number 226 in the 14th annual VARBusiness 500 ranking.

The VAR 500 list details the leading revenue producers among technology integrators and technology Solution Provider organizations in North America. The list's ranking is based on gross worldwide revenue of hardware and software sales, as well as earnings from professional and managed information technology (IT) services.

"Over the last year, we have seen significant revenue growth in all aspects of our business and this award validates our position as a top technology integrator," said Maurice B. Tosé, Chairman, President and CEO of TCS. "This is the third consecutive year we have been recognized for our financial achievements, and we will continue toward providing our customers with the best wireless data communications technology."

TCS provides wireless and VoIP E9-1-1 network-based services, secure deployable communication systems, engineered satellite-based services, and commercial location applications, like traffic and navigation, using the precise location of a wireless device. TCS also pioneered the world's first wireless location platform for cellular E9-1-1 in 1996 and is leading the advancement of wireless location-based technology with multiple patents in this area.

"The indirect sales Channel for technology products and services drives two-thirds of all technology sales in the U.S., and the Solution Providers who make up the Channel are the primary influencers of business technology decision making. This is why the VAR 500 is such an important list, because these are the top Solution Providers in the industry, and we salute each of them for their stellar performance," said Robert C. DeMarzo, senior vice president and editorial director, Everything Channel.

The complete listing of the VARBusiness 500 is available in the June 2, 2008 issue of VARBusiness, the business magazine that provides strategic insight for technology integrators.

To enter the 2008 ranking of the 500 largest North American solution providers, system integrators, VARs and IT consultants, companies were asked to complete an online questionnaire to determine prequalification. In February 2008 VARBusiness conducted extensive research and analyzed the data. Independent data sourcing (e.g., SEC filings, annual reports, etc.) also was conducted. Finalists were ranked according to their fiscal year 2007 revenue, based only on their reseller-related services business.
