FORE SYSTEMS AND GENERAL INSTRUMENT ANNOUNCE PLANS TO JOINTLY DEVELOP
ATM-BASED CABLE MODEM NETWORK SYSTEM

SYSTEM TO ENABLE ADVANCED HIGH SPEED COMPUTER SERVICES TO HOMES AND
BUSINESSES INCLUDING INTERNET ACCESS, INTERACTIVE GAMES, AND WORK-
AT-HOME

Pittsburgh, PA and San Diego, CA - January 9, 1996- FORE Systems, Inc.
(Nasdaq: FORE), a worldwide leader in networking products based on
asynchronous transfer mode (ATM) technology, and General Instrument
Corporation (NYSE: GIC), a world leader in cable and satellite systems,
today announced their plans to jointly develop a high-speed, ATM-based
telecommunications network system. The system is designed to enable
broadband telecommunications operators to provide high-speed, two-way
communication services to computers over hybrid fiber coax (HFC) cable TV
plants.

The network enables the delivery of full motion video in real time to the
personal computer, in addition to Internet and online service access, and
a multimedia library featuring a variety of CD ROM titles on demand. It is
anticipated future applications will be developed that leverage the
network's capability to integrate video into multimedia applications,
creating an entirely new generation of video- based media.

The system is designed to provide a computer connection at speeds of up to
25 Mbps, hundreds of times greater than today's fastest telephone computer
modems. Customers will enjoy substantially more rapid access to their
current on-line services and dial-up connections. Additionally, the high
transmission speeds and dedicated links will be able to support exciting
new capabilities and interactive services.

The development plans between FORE and GI, who have been cooperating for
over a year, are significant as they bring together two leading companies
in their respective fields. FORE's expertise is in building end-to-end ATM
solutions. According to Dataquest, FORE has a market share of nearly 65%
and has shipped more ATM local area network (LAN) products than all of its
competitors combined. GI is a leading provider of video, audio and data
delivery systems.

"We are very enthusiastic about our partners working together to deliver
high performance network technology that can take advantage of a rich
Internet and also deliver the Quality of Service that multimedia and
broadband applications require," said Craig Mundie, senior vice president,
Consumer Systems Division at Microsoft. "Microsoft has worked closely with
FORE on ATM technology and standards for the past two years and with GI on
set-top box technology. We believe this announcement will help speed
Microsoft's efforts to bring new services to PCs and televisions."

Mike Ozburn, vice president and general manager, Telecommunication Network
Systems business unit of the GI Communications Division, commented, "The
creation of standards for cable modem systems will be an important step
toward making this technology readily available to the consumer. FORE and
GI have been proactively working with several industry groups and
standards bodies to help shape these standards to ensure that our system
is compatible."

FORE is a principal member of the ATM Forum, Internet Engineering Task
Force (IETF), and International Telecommunications Union (ITU). GI is a
contributor to the ATM Forum, the Moving Pictures Experts Group (MPEG),
and the IEEE 802.14 standards committee on a Standard Protocol for
Cable-TV Based Broadband Communications Networks. Both companies have also
been working with the cable industry through CableLabs on its High Speed
Cable Data Services program providing a framework for vendor
interoperability. Both FORE and GI intend to design the ATM-based cable
modem network system to be compatible with industry standards, as each has
done with previous products.

"The inherent switching nature of ATM will facilitate the formation of very
high-speed wide area and global networks that can be directly accessed
from the cable TV network similar to the ubiquitous access currently
supported by phone modems. To create such an advanced network, GI plans to
develop an end-to-end ATM communications system working cooperatively with
FORE as a development partner," said Ozburn.

According to industry analysts, there will be an estimated 300,000 cable
modem PC households in 1997, rising to 12.9 million in 2004.

"This represents a very exciting opportunity for FORE Systems," said Eric
Cooper, chairman and CEO of FORE Systems. "We have successfully
demonstrated our ability to deliver complete ATM solutions to benefit
businesses, government, and communications service providers worldwide.
Now, with General Instrument, we plan deliver a cost-effective ATM
solution to the home."

The network solution will be based on an end-to-end ATM system. Servers and
content gateways at the cable head-end are designed to be connected
through FORE Systems ATM switching products to a head- end processor which
will be jointly developed by FORE and GI. The processor will send traffic
downstream over an HFC infrastructure to a cable modem from GI, that is
connected to the home computer equipped with a standard network interface
card (NIC), such as a FORE 25 Mbps ATM adapter card. Upstream traffic will
travel over the same path in reverse at lower speeds. GI is developing a
specialized network navigator for use with the system.

The end-to-end ATM-based solution is designed to offer several advantages
over other proposed cable modem systems. The network is highly scalable,
serving larger networks and higher bandwidths more easily than Ethernet-
based products. The system also can deliver the guaranteed Quality of
Service needed for effective delivery of multimedia applications. It will
also provide operators with the option of billing by usage rather than
connect time. Finally it supports an open architecture using industry
standard interfaces.
