March 16, 2005. RADVISION Completes the Acquisition of Millennium Portfolio Company First Virtual Communications, Inc.

RADVISION (NASDAQ: RVSN) reported that it has completed the previously announced acquisition of substantially all of the operating assets, intellectual property and customer contracts of First Virtual Communications, Inc. (FVC) and its wholly-owned subsidiary CUseeMe Networks, Inc. The closing followed approval of the transaction by the United States Bankruptcy Court for the Northern District of California. FVC filed for protection under Chapter 11 on January 20, 2005.

"We believe the combination of the technologies of RADVISION and FVC, including their Click to Meet communications platform, yields a powerful desktop oriented solution that bridges all uses, whether they are in the meeting room, at the desktop, or on the road into a seamless multimedia communications architecture," said Gadi Tamari, CEO of RADVISION.

"FVC has been a pioneer in the desktop conferencing and communications space with an award-winning, web-based solution that offers all of the features necessary for personal multimedia communications. With a track record of over seven years of delivering desktop-oriented communications solutions, FVC developed a large customer base in both the federal and enterprise markets -- a customer base we intend to continue to serve and expand."

Killko Caballero, RADVISION's Senior Vice President of Enterprise Strategy, will also head a new division comprising the former FVC assets. Prior to joining RADVISION, Mr. Caballero served as president and CEO of FVC as well as Chief Technology Officer and later the Chairman, President and CEO of CUseeMe, before it was acquired by FVC. He commented: "We have hired a significant number of key FVC employees in every area of the company's operations and welcome them to RADVISION. Our focus now is to deliver seamless service and support to all FVC customers as well as to fully develop the substantial potential of our combined technologies."

The assets of First Virtual Communication and its wholly-owned subsidiary CUseeMe Networks, Inc. include contracts and technologies related to providing integrated real-time voice, video, and Web collaboration/communication solutions to enterprises, service providers, and portals. FVC's flagship product, Click to Meet, provides a distributed software-based rich media communications platform and downloadable Web browser-based communications software client that transparently passes through firewalls - making it ideal for consumer, video call centers, and extranet applications. Click to Meet also features tight integration with commonly used enterprise desktop applications and network solutions including Microsoft Outlook, Microsoft Active Directory, Microsoft Office Live Communications Server 2005, IBM Lotus Instant Messaging, and IBM Domino directory.
