         PICTURETEL, FIRST VIRTUAL COMMUNICATIONS, AND CUSEEME NETWORKS
                   ANNOUNCE AGREEMENT FOR A STRATEGIC ALLIANCE

     PARTNERS TO INTEGRATE TECHNOLOGY AND MARKETING PROGRAMS TO DELIVER THE
         INDUSTRY'S FIRST END-TO-END RICH MEDIA COMMUNICATIONS SOLUTION


ANDOVER, MA, SANTA CLARA, CA, AND NASHUA, NH, MAY 8, 2001 - PictureTel(R)
Corporation (NASDAQ: PCTL), FirsT Virtual Communications (NASDAQ: FVCX), and
CUseeMe Networks (NASDAQ: CUSM) today announced an agreement for a strategic
technology, marketing, and distribution alliance that is expected to deliver the
industry's most powerful end-to-end rich media collaboration solution for
enterprises and service providers.

         By combining the three companies' best-of-breed audio, video, web
collaboration, application server, multipoint server and client technologies,
this strategic alliance is expected to create the most scalable and functional
rich media communications solution on the market.

         "Today's announcement underscores our commitment to deliver a full
spectrum of multi-media collaboration solutions incorporating iPower(TM),"
states Dr. Norman Gaut, PictureTel's chairman of the board and chief executive
officer. "This partnership will result in the first true fully integrated,
end-to-end solution that will simplify the implementation, management, and
utilization of rich media collaboration capabilities at the enterprise level.
Importantly, we will take advantage of the combined strength of our global
direct and multi-level distribution channels to significantly expand our
delivery of these industry leading products."

         Under the terms of the letter of agreement executed today, PictureTel
will provide engineering personnel and a license for its PurePoint(TM) rich
media communications solution to First Virtual Communications, which will
integrate its key features into First Virtual Communication's Click To Meet(TM)
platform.


                                    - more -



         In addition, the Companies will cross-license their unique
technologies, including iPower and the CUseeMe Networks' software video client,
for integration into each party's products, enabling the delivery of a fully
integrated and complementary end-to-end solution. Specific financial terms were
not disclosed. However, in consideration of technology, marketing, and sales
contributions, PictureTel will receive warrants of up to 15 percent of First
Virtual Communications' current outstanding common stock, exercisable upon
PictureTel's achievement of specified milestones.

         "Our mission is to change the way people communicate. This is no simple
task. Each of our three companies has approached the challenge with a different
set of capabilities. Only by combining our efforts will we accelerate the
delivery of a solution that our customers require to make collaboration seamless
and simple," states Ralph Ungermann, chairman of the board and chief executive
officer, First Virtual Communications. "We are 100 percent committed to
delivering an end-to-end enterprise and service provider solution and are
continuing our expansion into the consumer market. Our merger with CUseeMe
Networks and our agreement for an alliance with PictureTel, announced today, are
critical steps towards achieving these goals."

         PictureTel's PurePoint is a web-based bridge control application that
uses directories, calendars, and messenger services to automate point-to-point
and multipoint conferences. Click to Meet, with its simple point-and-click
interface, is a gatekeeper-based application and management platform that
seamlessly integrates videoconferencing, streaming, and data collaboration into
an easy-to-use, web-based rich media communications solution. The CUseeMe(R)
Videoware solution, a complete software-based rich media communications
environment from CUseeMe Networks that interfaces with existing messaging and
collaboration environments such as Microsoft(R) Exchange(TM), will be integrated
with First Virtual's Click to Meet as part of the merger announced recently
between the two companies.

         The agreement also provides for integration with CUseeMe Networks'
award-winning Multipoint Control Unit (MCU), the CUseeMe Conference Server. When
coupled with CUseeMe Networks' powerful web-based software video client, the
CUseeMe Conference Server addresses the needs of the enterprise desktop and
consumer markets by providing robust and cost-effective solutions for
large-scale deployment.

         "Organizations around the world and across vertical market sectors are
racing to figure out how to make best use of their in-demand knowledge resources
to achieve competitive advantage," states Killko Caballero, chairman of the
board, chief executive officer, and president, CUseeMe Networks. "We believe
there is no question that these collaboration tools will be a business
necessity. Working together, our companies are well positioned to take advantage
of this growing market."

         The collaboration is subject to the completion of the merger between
CUseeMe Networks and First Virtual Communications. The definitive agreement for
the collaboration is expected to be executed by the parties by August 1, 2001.


DELIVERING A COMPLETE RICH MEDIA CUSTOMER SOLUTION

         Together, the organizations plan to deliver the industry's first
integrated end-to-end rich media communications solution, which will include:


                                    - more -



         -        Application servers that automate management of video and
                  audio telephony, data collaboration, and streaming across IP,
                  ISDN, DSL, PSTN, and ATM networks
         -        Scheduling, directory, and messenger services
         -        Conference room and desktop clients
         -        Multi-point conferencing units, gateways, and gatekeepers

         Most important, the alliance is expected to deliver significant
benefits for the customer. First, through the combination of PurePoint and
Click to Meet, end users will have access to the most functional and scalable
rich media management application on the market today. Secondly, the
incorporation of the iPower feature set into all jointly offered products
(end-point, MCU, gateway, gatekeeper, application server) is expected to
provide the world's first end-to-end rich media solution that should allow
customers to benefit from the superior features of iPower in multipoint as
well as point-to-point conferences. This means that customers may expect to
collaborate using 14kHz Siren(TM) audio and engage the power and simplicity
of People+Content(TM) in bridged calls, while enjoying the additional
automation/control benefits of Click to Meet. Thirdly, customers may expect
to see new products coming to market faster and with richer feature sets as
the three companies focus on their core development strengths and collaborate
to eliminate development overlap.

         "End users have clearly been asking for an end-to-end rich media
collaboration solution for the enterprise that is easy to deploy and simple to
use," states Dr. S. Ann Earon, president, Telemanagement Resources
International. "This alliance and the commitment to cooperation between
PictureTel, CUseeMe Networks, and First Virtual Communications makes great
sense."

         The parties have agreed to engage in a worldwide strategic marketing
effort to drive the expansion of the market. All parties have agreed to sell
each other's products, in addition to the new products to be developed by the
partnership, in bundled and stand-alone configurations specific to their
respective customers' requirements. Harnessing the combined global distribution
capabilities of the three organizations, customers are expected to have access
to the most advanced portfolio of collaboration solutions and services in the
industry.

         In March 2001, First Virtual Communications and CUseeMe Networks
announced that they have agreed to merge to create one of the market's leading
rich media communications providers. The merged company will retain the name
First Virtual Communications, Inc. By harnessing First Virtual's expertise in
broadband rich media networking and CUseeMe Networks' state-of-the-art
software-based visual collaboration technologies, the combined company plans to
deliver integrated end-to-end solutions seamlessly across multiple network
types, including IP, ISDN, ATM, PSTN, and DSL to enterprises, service providers,
and consumer markets worldwide.

      Greenbridge Partners LLC acted as exclusive financial advisor to
PictureTel and FVC in connection with the strategic alliance.
