METROWERKS ANNOUNCES SUPPORT FOR MICROSOFT AFC JAVA CLASSES

AUSTIN, Texas-April 2, 1997-At the Software Development West Conference and
JavaOne, Metrowerks Inc. (NASDAQ: MTWKF, TSE/ME:MWK), one of the world’s
leading providers of software development tools, today announced that
Metrowerks’ CodeWarrior will offer full support for Microsoft’s recently
announced Application Foundation Classes (AFC), a comprehensive set of
cross-platform, value-added class libraries written entirely in Java.

These classes provide small, fast and flexible graphics, user interface and
multimedia capabilities in a suite of highly functional Java class
libraries. This enhances development of rich, sophisticated cross-platform
Java applications while saving on valuable development time. Metrowerks
will provide support for AFC in upcoming versions of its CodeWarrior Gold
Integrated Development Environment hosted on the Microsoft Windows 95 and
Windows NT operating systems and Mac OS.

“We have worked closely with Microsoft and delivered the fastest, most
robust, virtual machine on Mac OS,” said Greg Galanos, president and chief
technology officer of Metrowerks. “We look forward to continuing and
expanding our relationship by providing the Microsoft Application
Foundation Classes as part of the CodeWarrior product line. It’s good to
see Microsoft investing in new Java class technology that makes Java better
for all developers on all platforms.”

“We are pleased to see a leading development tools vendor such as
Metrowerks provide support for AFC in their Java tools,” said Tod Nielsen,
general manager of Developer Relations and Platform Manager of Microsoft.
“With their help we are able to rapidly extend our cross-platform Java
class technology to a large pool of software developers on multiple
platforms.”
