Melville, New York, December 5, 2002 - Andrea Electronics Corporation (Amex: AND - News), a leading provider of hardware and software audio input technologies, and Marconi (MONI), a global telecommunications equipment and solutions company, announced today that the parties have signed a license agreement for Marconi to integrate a number of Andrea's proprietary audio software technologies into the Marconi ViPr Virtual Presence System (ViPrTM). The ViPr conference system is a new network appliance developed by Marconi that enables secure, high resolution, real-time, multimedia communications between people in geographically dispersed locations. This revolutionary communications system, enabling real-time collaboration and multi-point conferencing, turns the vision of virtual presence into an everyday tool for improving executive decision-making.

The addition of Andrea Electronics' hands-free audio system includes an advanced stereo version of Andrea's patented EchoStop®, as well as its patented DSDA® 2.0 and PureAudio® 2.0 noise canceling algorithms, among others. The implementation of Andrea's microphone array, which is embedded in the monitor of the ViPr system, together with the proprietary audio technologies, allows users to carry on a discussion at normal conversational levels, even in a noisy room. Background noise is cancelled out, as is all the sound coming from the speakers, to create an environment that breeds natural conversations.

"After extensively reviewing several microphone technologies available in the market today, Andrea Electronics' portfolio proved to be an overwhelmingly superior solution for this breakthrough virtual presence system," said Dennis Rowlands, vice president, Application Platforms, Marconi's Broadband Routing & Switching group. "Audio quality is a critical element for any real-time, multi-point communications system, and with Andrea Electronics' audio technologies, Marconi's ViPr system provides a virtual presence environment that dramatically accelerates and enhances executive decision-making in government, military and corporate enterprise markets."

"The need for superior audio quality is increasingly critical in the video conferencing markets as multi-point conferencing alternatives are becoming more common for conducting mission-critical meetings," said Christopher P. Sauvigne, President and Chief Executive Officer of Andrea Electronics Corporation. "We are proud of what we've accomplished with Marconi's ViPr system, and we look forward to continued successes in the growing video communications market."

Real-time, global demonstrations of Marconi's ViPr system were conducted at SC2002, a conference of high-performance computing, networking and data technologies, in the Baltimore Convention Center, November 18 - 21, where sites in Honolulu, HI; Belleville, IL; Stuttgart, Germany; and Washington, D.C. were linked with Marconi's booth. ViPr is also being demonstrated at the U.S. Naval Research Lab in Washington, D.C., and through every-day user-experiences in several government locations.
