Business Editors/High-Tech Writers

RALEIGH, N.C.--(BUSINESS WIRE)--March 17, 2003

Summus, Inc. (USA) (OTCBB: SUMU), a developer of applications and information processing tools that optimize the wireless multimedia experience, and AccuWeather, the world's leading commercial weather service, today announced that the companies have joined forces to develop a suite of wireless applications containing dynamic weather content. The suite will be powered by BlueFuel(TM), Summus' Superfast, Superthin(TM) platform tailored for efficient and seamless interaction with information in the mobile environment. The applications from AccuWeather.com and Summus provide wireless users with local, national and international weather forecasts, including radar and satellite images, along with continuous updates and alerts on changing weather conditions.

The AccuWeather.com content provides highly accurate localized weather reports with text and images using Summus' extremely efficient representation of weather data and its revolutionary user interface designed specifically for mobile phones. The application delivers five-day forecasts for more than 43,000 U.S. zip codes plus international locations, including detailed information on temperature, precipitation, wind speed, visibility, humidity, UV index, pollen count and overall air quality. Satellite and regional radar images are continuously updated, providing both static and animated graphics on changing weather patterns.

"Many individuals rely on accurate weather reports to determine how adverse weather conditions might impact their daily activities. Individuals no longer have to rely on conventional methods to stay abreast of current and future weather conditions," says Dr. Joel N. Myers, founder and president of AccuWeather, Inc. "We are delighted to work with Summus because of the strength of their BlueFuel platform, which creates a high quality experience for wireless users and quickly delivers time-sensitive data."

AccuWeather has become a leader in accurate weather forecasting by providing more than 16,000 paying customers in media, business, government and institutions with regular weather updates and by reaching millions more through the AccuWeather.com website. AccuWeather also provides content for more than 600 Internet sites, including CNN Interactive, ABC's owned and operated stations, The Associated Press(R), The Washington Post and The New York Times.

"Weather reports represent one of the major application areas for wireless users, and we see this collaboration as proof positive of the capacity of BlueFuel, as AccuWeather is one of the most well recognized names in weather forecasting, said Bjorn Jawerth, CEO of Summus. "This application will showcase BlueFuel and its capability to take the user experience to an entirely new level and to deliver rich, dynamic radar maps and animations of changing weather patterns."

The AccuWeather.com application will be built on QUALCOMM's BREW(TM) platform and will be available by early Q2 of 2003 to mobile carriers that support BREW. The application will also be built to run on J2ME and Symbian platforms and available to carriers supporting these platforms.

Summus' BlueFuel platform enables service providers, content providers and handset manufacturers to create and deliver robust mobile applications quickly and on a much wider range of devices and operating systems than competing technologies. The platform and architecture gives developers the tools necessary to easily build applications for today's resource-constrained wireless environment, while providing a superior user experience.
