TradeWave honored twice by industry groups.

AUSTIN, Texas--(BUSINESS WIRE)--Sept. 17, 1996--TradeWave Corporation, a subsidiary of SunRiver Corporation (NASDAQ:SRVC), received two Internet industry awards this past week for its security solutions.

TradeWave received an Internet & Electronic Commerce Award for Internet Infrastructure at the Gartner Group Fall iEC Conference and Exhibition. Additionally, TradeWave received an Internet and Intranet Commerce "Best of Class--Energy and Utilities" Award at the IDG Internet Commerce EXPO (ICE) Conference and Exhibition.

The iEC Awards were judged by Gartner analysts and Information Week editors, and ICE Awards were judged by Computerworld magazine and International Data Group (IDG). These awards seek to encourage expanded business activities through the Internet and corporate intranet solutions.

TradeWave was recognized as a winner for its creation of a secure electronic market on the Internet for wholesale sellers and purchasers of electricity who need current information on transmission availability and prices. The system, known as Open Access Same-Time Information System (OASIS), is the electric power industry's response to a mandate from the Federal Energy Regulatory Commission (FERC). The mandate called for utilities to make available transmission grid capacity electronically over the Internet to encourage competition in wholesale power markets.

A task force representing over 350 investor-owned electric utilities, public utilities and utility cooperatives selected BSG Alliance/IT, ISAVE Cegelec ESCA, and TradeWave Corporation to develop and implement an advanced system for electronic commerce. The task force controls approximately 70 percent of the transmission line mileage in the U.S. OASIS is scheduled to be in production in November, 1996. This system is expected to secure over $20 billion in transmission mileage when the system is fully operational.

"The security of this system was paramount to the electric power industry, as were flexibility and the ability to easily administer the system," said Dr. Alexander Cavalli, Chief Technical Officer of TradeWave. "The TradeWave solution is based on the strongest public-key infrastructure technology available today, and that's what the electric power community needed."

The new network is based on Trade VPI, the latest security technology from TradeWave Corporation. Trade VPI creates a "Virtual Private Internet" (VPI), where mission-critical transactions can be performed, such as the posting and reservation of electric power transmission capacity. The security architecture provided by Trade VPI features a public-key certification service, which enables security authorization at the individual user level; this kind of control is crucial for a mission-critical business system like OASIS. Also, users can access various OASIS group data from a single logon.

TradeWave's partner, BSG, is a leader in the integration of high-performance information technology for business and commerce, BSG will develop and implement the system that allows the interaction between buyers and sellers. The company is a wholly owned subsidiary of Medaphis Corporation (NASDAQ:MEDA), a major provider of business management and information technology services. BSG can be reached on the Internet at http://www.bsginc.com.

Cegelec ESCA is leading the systems application design effort. Cegelec ESCA is a major supplier of real-time systems for energy management, supervisory control and data acquisition, and power marketing.

TradeWave Corporation is a subsidiary of SunRiver Corporation (NASDAQ:SRVC), a provider of network-centric computing solutions. TradeWave develops and markets software products and services that enable secure, business-to-business electronic commerce over the Internet. In 1993, TradeWave delivered the first commercial intranet and secure VPI.

Based in Austin, Texas, the company was founded in 1991 as the Enterprise Integration Network (EINet) within the Microelectronics and Computer Technology corporation (MCC), a research consortium of the nation's leading high-tech companies such as IBM, Kodak, Hewlett-Packard, and AT&T.
