NETSCAPE ANNOUNCES NEW REAL-TIME AUDIO AND VIDEO FRAMEWORK FOR INTERNET
APPLICATIONS

January 31, 1996 -- MOUNTAIN VIEW, California -- Netscape Communications
Corporation (NASDAQ: NSCP) today announced Netscape LiveMedia, a
standards-based framework for bringing real- time audio and video to the
Netscape open software platform. As the cornerstone of its new framework,
Netscape announced the signing of a definitive agreement to acquire
InSoft, Inc., a leader in network-based communications and collaborative
multimedia software for the enterprise.

InSoft's applications include Communique! for desktop collaboration and
videoconferencing, InSoft Network Television or INTV! for distributed
digital video, and CoolTalk and CoolView for Internet audio, video and
data communications on Windows, Windows95 and UNIX based platforms.
Netscape plans to use InSoft's technology to create the Netscape LiveMedia
framework, which it plans to make a standard component in future Netscape
clients, servers and tools. Netscape LiveMedia framework will enable users
to have easier access to new Internet applications such as audio and video
on-demand, real-time video conferencing and Internet telephony.

In addition, eleven technology-leading companies announced plans to support
Netscape LiveMedia, which is based on open standards and interfaces that
will enable Netscape and third-party real-time audio and video products to
interoperate. Companies that announced their support are Progressive
Networks, Adobe Systems, Digital Equipment Corp., Macromedia, NetSpeak,
OnLive!, Precept, Silicon Graphics, Inc., VDOnet, VocalTec and Xing. The
Netscape LiveMedia framework will be based on the Internet Realtime
Transport Protocol (RTP), RFC number 1889, and other open audio and video
standards such as MPEG, H.261 and GSM to enable products from these and
other companies to work together seamlessly, providing users with a range
of real- time audio and video capabilities on the Internet. Netscape will
publish the LiveMedia framework on the Internet, openly license key
technology components of it, and work with the Internet standards bodies
to facilitate the adoption of this technology as a formal Internet
standard.

"By integrating InSoft's technology within our existing software
architectures, we can extend the Netscape software platform into a
foundation for real-time Internet and Intranet communications," said Jim
Barksdale, president and CEO of Netscape. "Through this agreement with
InSoft, Netscape will also gain InSoft's great team of people who bring
best-of-breed expertise in delivering real-time audio/video applications
to the enterprise."

"The Internet is a strategic component of our open, enterprise approach to
collaborative multimedia," said Dan Harple, chairman and CEO of InSoft.
"Real-time multimedia collaboration helps to bring people together across
a network, a goal that both Netscape and InSoft share. Without question,
we are extremely excited about joining the Netscape team and helping to
develop the Netscape LiveMedia framework."

Netscape intends to purchase 100 percent of InSoft, a privately held
company, for 1.96 million shares of Netscape stock (adjusted to reflect
the Netscape 2-for-1 stock split which was approved by shareholders on
January 23, 1996), to be accounted for as a pooling of interests. The deal
is expected to close on or before March 31, 1996.

InSoft, Inc., located in Mechanicsburg, Pennsylvania, was founded in 1992
by Dan Harple and Rich Pizzarro to develop and market collaborative
multimedia software products for the expanding desktop workstation market.
The company currently employs 71 people. InSoft's OpenDVE Collaborative
Multimedia Framework enables cross-platform collaboration between PCs and
UNIX workstations, transparent connectivity between a wide range of
networks, and interoperability between a range of video offerings.

Netscape plans to integrate InSoft's products in two phases. In the first
phase, the combined companies will develop the LiveMedia framework and
continue to promote InSoft's OpenDVE software architecture and development
toolkits; Communique!, INTV!, CoolTalk and CoolView applications, and the
GlobalConference telecommunications gateway. In the second phase later in
1996, Netscape plans to integrate InSoft's real-time audio and video
capabilities into future versions of Netscape Navigator and Netscape
servers. In addition, Netscape expects that third-party developers will
offer a wide variety of add-on audio and video products based on the
LiveMedia framework.

Netscape also announced today that it has signed an agreement with Voxware,
Inc., to license that company's compression/decompression (codec)
technology to plug into the Netscape LiveMedia framework. Codecs from
other companies can also be incorporated into the extensible framework.

Voxware, Inc. is a privately-held developer of advanced voice processing
software, based in Princeton, NJ. Voxware's ToolVox digital voice
technology enables high-quality, real-time voice communication across the
Web, while requiring only 2400 bps of bandwidth. Using the ToolVox
cross-platform encoder and player software, developers can compress voice
53:1; download or stream voice files in real time and add a variety of
voice effects. This combination of compression and quality simplifies
adding voices to the Web. This technology will help to provide widespread,
reliable voice delivery to any user with a Web connection. The
incorporation of the Voxware codec in LiveMedia is an example of how this
modular framework can accommodate technologies from various companies.

"We're delighted that our agreement with Netscape will make ToolVox a key
component of the core technology framework for Netscape LiveMedia," said
Michael Goldstein, president and CEO of Voxware. "We look forward to
working together to make real-time voice communications a natural and
everyday part of every Web user's experience."

"Enabling users to communicate and work together from any location -- and
in real time -- extends the Internet's power and reach to a new level,"
said Marc Andreessen, vice president of technology at Netscape. "The
Netscape LiveMedia framework will make a number of real-time audio and
video applications available to Internet users. InSoft and Voxware are
important to Netscape's strategy to deliver products based on LiveMedia,
and we will work with the technology-leading companies who are supporting
this interoperable approach to make real-time audio and video applications
an immediate reality."

Netscape LiveMedia represents a commitment to open Internet-supported
protocols and content definitions that transcend any single vendor,
including Netscape. Vendors adopting the LiveMedia Internet standards will
be able to offer products that interoperate with other LiveMedia
compatible products, making it easy for users to take advantage of
real-time audio and video capabilities on the Internet.
