RESTON, Va., and GAITHERSBURG, Md./Dec. 2, 2002 -- Comerica (NYSE: CMA), a leading financial services company, and AWS Convergence Technologies, Inc., which owns and operates the largest weather network in the world, announced today that Comerica's Technology and Life Sciences Division has provided AWS with a $2 million credit facility. The $1.5 million revolving credit line and $500,000 equipment term loan will be used to help AWS build and sell products across each of its rapidly growing business units.

"As owner of the world's largest weather network, AWS offers an invaluable service to a diverse user base, so we are pleased to provide the company with financial support through this credit facility," said Bradley Steele, regional manager in Comerica's Mid-Atlantic Technology and Life Sciences Division. "We are committed to serving the technology market, providing financial products and services to help both emerging and mature companies compete successfully for market share."

For nearly a decade, AWS has delivered high impact weather information to consumers, broadcasters, schools and industry. WeatherBugTM, the Web's only source for live, neighborhood weather conditions and personal forecasts, has been called the "fastest growing Web site in the world" by Forbes.com and was shown by Nielsen/Net Ratings to be the number one weather site in the world. The company's WeatherNet program is among the most sought-after weather reporting systems in the broadcasting industry; WeatherNet Classroom delivers real-time weather data to schools for teaching science and math; and MesoStreamer provides real-time weather information to energy companies to support power trading operations. In addition, AWS recently completed an agreement with the National Weather Service to provide real-time weather information to support homeland security.

"We wanted to work with a bank that has technology expertise and the ability to provide creative, flexible financial solutions," said Dan O'Connell, AWS's vice president of Finance and Administration. "We've established AWS as a dominant technology company in the field of weather, so we now look to expand our reach into new markets, and this credit facility will help us do that."
