RED HAT AND GRAMMAR ENGINE UNVEIL EMBEDDED DEVELOPMENT
TOOL RUNNING OPEN SOURCE SOFTWARE

PromICE.net?s Web Server Capabilities and Red Hat?s Open Source Solution Enables
Network-Based Access to Remote Target Development Hardware

RESEARCH TRIANGLE PARK, N.C.--April 4, 2001--Red Hat, Inc.
(Nasdaq:RHAT), the leader in developing, deploying and managing open source
solutions, today announced that Grammar Engine, Inc.?s PromICE.net, a memory
emulator that allows embedded developers to collaboratively build applications over the
Internet, runs on uClinux operating system technology that was implemented by Red Hat.
PromICE.net, based on the NetSilicon processor, is an embedded development tool that
runs open source software. Its Web server capabilities enable embedded developers to put
their target on the Internet and allow co-workers to access it from anywhere in the world
for development of applications.

"The incorporation of Red Hat Linux into the memory emulator represents a
breakthrough for embedded developers who want to avoid the limitations imposed by
proprietary software in their development environment," said Michael Tiemann, CTO of
Red Hat. "This is an opportunity for developers to use Linux to add features, options and
programs to PromICE.net that are needed for their individual development environments
without experiencing the shortcomings of the proprietary model."

"Grammar Engine has chosen to work with Red Hat and use uClinux and support GPL
software because of the tremendous opportunities that this offers to embedded
developers," said Arvind Rana, CTO of Grammar Engine Inc. "Since our customers are
embedded software developers, we understand that they want ultimate control over their
development tools. Access to open source code provides us the opportunity to co-
develop, with each of our customers, the exact tool they need."
