TruePosition and Cingular Sign National Multi-Year Agreement For GSM Location Solution

TruePosition's U-TDOA Location Solution Provides High Accuracy For Anyphone, Anywhere™

KING OF PRUSSIA, Pa. and ATLANTA, Ga., March 10, 2003 - TruePosition Inc., a leading provider of location-based technologies today announced a multi-year agreement with Cingular Wireless to provide a location-based E-911 technology for Cingular's GSM networks. The same agreement also states that Cingular has contracted to upgrade its existing TruePosition location system to the TruePosition GSM location product as well.

As previously announced in the Fall of 2002, TruePosition's U-TDOA location solution complies with the regulatory mandated standards. In testing conducted on Cingular's Wilmington, Delaware system, 67% of calls were located within 47.1 meters and 95% of calls were located within 112.2 meters. TruePosition has currently deployed over 4000 units in cell sites in numerous markets across the United States.

This multi-year agreement is designed to support Cingular with meeting the FCC enhanced 9-1-1 mandate. The FCC requires wireless carriers to provide designated public safety agencies with location information for 911 calls in accordance with the following standard for network-based location technologies such as TruePosition's: 100 meters for 67% of calls and 300 meters for 95% of calls.

"TruePosition brings a fresh perspective backed by years of experience and the largest body of location services intellectual property in the industry.
