San Francisco, CA--April 16, 1992--GO Corporation announced today the
commercial release of PenPoint. This award-winning operating
system--uniquely designed to meet the needs of mobile computer users--is
enabling an exciting new mobile, pen computing market.

PenPoint incorporates a number of enhancements which include; an advanced
32-bit architecture, new levels of ease of use, and a new handwriting
engine--GOWrite. Some of the most exciting news today though is the broad
range of breakthrough applications and development tools designed
specifically for PenPoint.

Advanced 32-bit Architecture 

PenPoint has been designed as a modern 32-bit, preemptive multitasking,
general-purpose operating system uniquely suited to mobile pen computing.
The system has been in development for four years. Since its initial
unveiling to the developer community in January of 1991, PenPoint has been
ported from a 286 to a 386 platform. The 386 support offers higher
performance as well as protect mode operation, preemptive multitasking,
and support for virtual memory.

The processing power of the 80386 gives PenPoint the bandwidth and
performance for delivering truly powerful system and application
functionality. The PenPoint operating system utilizes the protect mode of
80386, which greatly increases overall system reliability. An important
benefit of the protect mode is that if an application should crash
PenPoint would not be affected. As a processor-independent, flat memory
model operating system, PenPoint is capable of supporting RISC-based
machines as well.

Preemptive multi-tasking has always been an important feature of
PenPoint--mobile computing requires instant access to critical
information. The user's pen takes priority even while background tasks
such as handwriting and communications are processing.

A new feature of PenPoint 1.0 is the ability to use virtual memory. This
allows the system to utilize a hard disk as an extension to physical RAM.
Users are then able to open more documents simultaneously or use large
documents without having to add physical RAM. With a focus on lighter,
Less expensive and more durable mobile pen computers, this feature
optimizes the efficiency of the system.

New Level of Ease of Use 

Since the Developer Release of PenPoint, GO has conducted over 2300 hours
of formal user testing to further refine PenPoint's ease of use. Based on
this research, GO has incorporated a number of key enhancements including
a new and integrated Settings Notebook where users can quickly access all
of their system preferences and installed software. New standard
applications menus provide more consistent access to features and
functions across applications. GO has also designed Quick Start tutorials
which the user can use to get started with PenPoint and PenPoint
applications in ten minutes or less. These tutorial documents are bundled
with PenPoint (for the operating system as well as PenPoint applications).
GO's software partners are creating Quick Start tutorials for their
applications so that whenever a user gets a new application they can look
for the QuickStart document to rapidly familiarize themselves with the
program. Quick Start gives users a tool to become productive immediately.

GOWrite 

GO has developed an entirely new handwriting recognition engine for the
release of PenPoint. This new technology was designed specifically to
improve upon the developer release engine in areas that GO's extensive
User Research program identified as important for business applications.

GO Corporation has invested heavily in the development of a powerful
general-purpose handwriting recognition system. GO has also developed a
research program chartered with developing "real-world" metrics and
methods to evaluate the performance of the system for a wide variety of
tasks. The GOWrite engine focuses on a number of areas for improved
performance including; much better "walk-up" accuracy (no training or
practice), much more robust recognition, more tolerance of sloppiness and
shape variation, and much broader coverage. GOWrite also recognizes more
symbols than the previous engine (>25 punctuation characters) and a
greater variation of writing styles using a database of over 700,000
handwriting and gesture samples.

"Walk-up" accuracy is of particular importance in that some customers do
not have the patience to train the system to recognize their writing. In
addition, extensive training is impractical for some business
applications.

GO is committed to ensuring that the best handwriting recognition
technology is available to users of PenPoint (regardless of whether or not
it comes from GO). The company is licensing its extensive database of over
700,000 handwriting and gesture samples to any handwriting ISV who has
ported their technology to PenPoint. In addition, GO has an active program
of supporting third party developers' efforts to port their recognition
systems to PenPoint.

Breakthrough Applications 

Over 30 breakthrough applications were demonstrated in the Product Showcase
at the PenPoint Premiere. Nearly all of them are designed from the ground
up to take advantage of PenPoint's pen and paper metaphor, tightly
integrated handwriting and gesture capabilities as well as the rich
object-oriented environment. New types of applications highlighting
different requirements of mobile users--notetakers, personal information
managers, communications, financial/spreadsheets--were featured in the
PenPoint Product Showcase. Rapid development of applications for PenPoint
is enabled through the benefits of object-oriented programming. The
modularity of the operating system allows for efficient code reuse and
generally results in applications which are quite small in size. The user
benefits from a consistency of ease of use across all applications and the
operating system itself.

Development Tools 

GO announced today the creation of a Custom Solution Alliance designed to
greatly increase the number of custom solutions developed for PenPoint.
Participants in this alliance include PenMagic Software, Inc., Pensoft
Corporation and Slate Corporation. In addition the 32-bit C compiler with
PenPoint support is available from Watcom. The Custom Solutions Alliance
provides a spectrum of development facilities for PenPoint, aimed at a
broad segment of customers. These customers range from commercial
applications developers to corporate developers, VARs and selected
end-users who want to create customized applications. The development
tools which are available through this program enable financial document
creation, customizable personal information management, database access,
and industry specific application development.

GO provided information on its PenPoint Information Architecture (PIA)
which has been added to the system in order to permit uniform access to
data, regardless of location, access method, and database management
system. PIA is a comprehensive architecture for database connectivity on
pen computers. It defines a database application interface providing
common access to multiple database servers.

PenPoint has garnered virtually every industry award for technical
excellence over the course of the last year. These include the Byte
Product Excellence Award, the Technical Excellence Award from PC Magazine,
a Most Valuable Product of the year Award from PC/Computing Magazine, the
Most Influential Product Award from Personal Computer World (UK), and PC
World's World Class award for most promising newcomer.

Today GO is shipping, the PenPoint Software Development Kit which includes
PenPoint and can be run on a variety of compatible desktop PCs. PenPoint
will be made available directly to end users of tablet systems through
IBM, NCR, GRiD, and other OEMs. The PenPoint Software Development Kit is
available from GO Corporation, Merisel and Ingram/Micro D beginning in
April.

GO Corporation, a privately held company headquartered in Foster City,
California develops, markets and supports PenPoint, a pen operating
system, and applications designed for mobile users, worldwide.
