Spyglass Provides Internet Solutions for IBM's Digital Set-top Box Reference
Platform

Spyglass Professional Services Ports Embedded Web Browsing Capabilities

Naperville, Ill. -- Monday, May 24, 1999 -- Spyglass (NASDAQ: SPYG)
announced today that the company will provide Internet solutions for IBM
Microelectronics' (NYSE: IBM) digital set-top box reference platform.
Spyglass Professional Services has ported Spyglass Device Mosaic, an
embedded Web browser, and Spyglass ThinGUI Library, a small footprint
graphics library, to Integrated Systems, Inc.'s (NASDAQ: INTS) pSOSystem,
the industry's leading real-time operating system used in the platform.

Spyglass' embedded Internet technologies provide a standards-based framework
for authoring content, creating applications and connecting to on-line
services. These technologies can be used to create Internet browsing
applications, electronic programming guides (EPGs), video-on-demand services
and a variety of other revenue generating applications and services
accessible from the set-top box.

IBM's digital set-top box reference platform provides the application
development environment needed to craft premier digital set-top box-based
services. This set-top box development environment is available with
quality-tested integrated hardware, software and development tools. With
IBM's set-top box reference platform users do not have to design from
scratch, minimizing time-to-market.

Set-top box manufacturers that select or are interested in IBM's set-top box
technology will contact Spyglass directly if they are interested in adding
Spyglass Device Mosaic to their Internet solution. Initially, interested
set-top box manufactures will target the digital video broadcasting (DVB)
market.

Spyglass has developed a comprehensive approach to advanced television that
is meant not only to leverage their strengths in technology and engineering,
but also to fully support IBM's manufacturing, marketing and development
capabilities. Spyglass is known as a solutions provider. Rather than simply
throwing technology at IBM, Spyglass took the time to understand how IBM
could best use Spyglass' technology and expertise in the interactive
television market.

"With Spyglass at our side providing proven Internet solutions, IBM will be
able to furnish the set-top box solutions our customers need to stay at the
forefront of this very competitive industry," said Bob Voskian, IBM
Microelectronics segment marketing manager, pervasive computing.  "Together
with Spyglass, IBM is positioned and deeply committed to helping our
customers succeed."

"Set-top box manufacturers are being forced to reduce hardware costs, while
still maintaining distinction," said Randy Littleson, Spyglass vice
president and general manager.  "IBM's reference platform, and Spyglass
Internet solutions, gives set-top box makers the ability to create the kind
of solutions they need to compete today and tomorrow."
