Immediate Release

MontaVista and Trolltech Join Forces:
Embedded Linux and Graphical Toolkit
Qt/Embedded and Hard Hat Linux to be Demonstrated at ESC- Spring

SAN FRANCISCO, April 9, 2001, -- MontaVista Software Inc., the
company powering the embedded revolution, and Trolltech AS have
joined forces to create a comprehensive and integrated embedded Linux

Developers can see a demo of MontaVista's Hard Hat=81 Linux=AE bundled
with Trolltech's Qt/Embedded at MontaVista's booth #122 at the
Embedded Systems Conference in San Francisco, April 10 - 12. The demo
will be running on a Compaq iPAQ that features a palmtop computing
environment designed and built with Qt/Embedded.

The new agreement combines Trolltech's Qt/Embedded development
framework with MontaVista's Hard Hat Linux distribution in a
comprehensive platform - OS, development framework, and embedded
windowing system - for embedded systems developers.

"The integration of Qt/Embedded with Hard Hat Linux creates a stable
and predictable platform for embedded systems developers," said Eirik
Eng, President of Trolltech.  "They can develop for the
MontaVista/Trolltech platform with confidence."

Kevin Morgan, MontaVista's vice president of engineering, said "This
alliance offers a complete embedded software solution that
significantly decreases time to market and lowers total development
costs. Bundling Qt/Embedded with our distribution creates a rich and
resource-efficient development and run-time environment."
Hard Hat Linux 2.0 Professional Edition is available direct from
MontaVista and MontaVista distribution channels worldwide as a
product subscription, providing the MontaVista Hard Hat Linux kernel,
utilities, development tools and one year of technical support. It is
open source, royalty-free, and built from 100% pure Linux sources.

Also available with Hard Hat Linux 2.0 Professional Edition are
expanded add-on capabilities, including packages for embedded Java,
High-Availability, legacy RTOS porting and emulation, and embedded
GUI development.

MontaVista will also make Hard Hat Linux 2.0 Journeyman Edition
freely available for technical evaluation and other uses.  A subset
of Hard Hat Linux Professional Edition, it targets a sampling from
all Hard Hat Linux CPU architectures and hosts on Red Hat Linux. It
can be downloaded from MontaVista's Web site or obtained on CD-ROM
for a nominal charge.

Hard Hat Linux 2.0 Professional Edition will be available the last
week of April 2001, and will be joined by additional functionality
and add-on technologies within 30 days via on-line distribution and
on CD-ROM. Trolltech's Qt/Embedded will be available on the Hard Hat
Linux platform in May 2001.
