Business Editors, Telecommunications Writers

SEATTLE--(BUSINESS WIRE)--Feb. 28, 2000

Cellular Technical Services Company, Inc. (Nasdaq:CTSC) ("CTS"), a leading provider of products and services for the tele-communications industry, commented today on the announcement of the proposed acquisition of KSI, Inc. ("KSI") by TruePosition, Inc., a wholly-owned subsidiary of Liberty Media (NYSE:LMG.A) (NYSE:LMG.B), in a stock acquisition of the company.

"In November," Stephen Katz, CTS Chairman and CEO stated, "we announced our entry into the geo-location market and our strategy to develop application-specific products and services that can be deployed with all major geo-location technologies. In fact, we are currently in the process of readying our first commercial application for field trials, which we expect to commence by the end of the year."

"Concurrently, we formed a strategic alliance with, and took an approximate 6.5% stake in, KSI, a pioneer in wireless location technologies. The combination of TruePosition and KSI should not only enhance the return on our initial investment in KSI but also align CTS with one of the premiere providers of wireless location technology and services," Katz added.

CTS provides real-time information processing and management solutions for the telecommunications industry. Over the past 11 years, CTS has used its extensive experience with real-time wireless call processing to create technologically advanced solutions for this industry, including integrated solutions for fraud management. Today, CTS is building a more diversified, vertically structured organization with a focus on providing a wide range of products and services.
