Verizon Wireless Signs E9-1-1 Contract With TCS

June 21, 2002



Verizon Wireless, the nation's largest wireless service provider, announced it has signed a five year agreement with TeleCommunication Systems, Inc. (TCS) (NASDAQ: TSYS), a key architect of wireless location and messaging software. TeleCommunication Systems will deliver Phase I and Phase II wireless Enhanced 911 (E-911) location service to approximately fifty percent of Verizon Wireless' cell sites nationwide.

Verizon Wireless recently reported to the Federal Communications Commission that it has achieved aggressive E-911 Phase II milestones by deploying handset-based technologies and network upgrades. Since 1998, Verizon Wireless, working with TCS, has been an industry leader in deploying Phase I E-911 service. Verizon Wireless uses the TCS Xypoint® Location Platform to provide the Public Safety Answering Points (PSAPs) with the wireless caller's phone number as well as location information for emergency assistance calls originated from wireless phones. As of April 15, 2002, Verizon Wireless has deployed Phase I service to more than 1,350 PSAPs throughout the country.

"TCS is proud to have strengthened its long-standing commitment to assist Verizon Wireless in meeting its Phase I and Phase II wireless E-911 deployment schedule," said Maurice B. Toseacute;, president, chairman and CEO of TeleCommunication Systems. "Verizon Wireless has continually been at the forefront in deploying technology enabling their subscribers to access emergency services."

The agreement consolidates the existing contracts that TCS had with several of the carriers that merged to form Verizon Wireless, including AIRTOUCH, PrimeCo and GTE Wireless and reinforces the long-standing relationship between the two companies.
