METROWERKS TO INCLUDE APPLE'S NEW OS TOOLS IN REGULAR CODEWARRIOR SUBSCRIPTIONS

CodeWarrior Tools for Apple's New OS to be Delivered in Incremental Releases

AUSTIN, Texas, December 20, 1996.-Metrowerks Inc. (NASDAQ: MTWKF,
TSE/ME:MWK), the leading provider of software development tools for the
Macintosh, today announced that CodeWarrior support for Apple Computer,
Inc.'s Next generation OS will be shipped to CodeWarrior customers as part
of their regular CodeWarrior subscription, in step with Apple's release of
its Next generation OS.

Metrowerks expects to have Objective C compilers and Objective C runtime
support in its C++ compilers hosted in CodeWarrior by the 1997 Apple
WorldWide Developers Conference. Metrowerks expects to have its CodeWarrior
compilers and linkers ported to Apple's Next generation OS simultaneous
with its availability from Apple Computer.

The CodeWarrior development environment will be supported on both Mac OS
and Apple's Next generation OS and the first developer release of the Apple
Next generation OS-hosted CodeWarrior will be made available to current
CodeWarrior subscribers at Macworld San Francisco 1998. Metrowerks compiler
offerings for Apple software platforms will include full support for 68K,
PowerPC and x86 applications development.

"Metrowerks intends to provide CodeWarrior support for Apple's Next
generation OS from day one," said Greg Galanos, President and Chief
Technology Officer of Metrowerks. "We will deliver CodeWarrior tools to the
developer community in an ongoing fashion to support current MacOS and
Apple's Next generation OS. Our intent is to make these tools available as
soon as possible to our customers in their regular CodeWarrior
subscription. CodeWarrior support of Apple's Next generation OS is in
alignment with our overall tools strategy and increases the availability of
CodeWarrior-hosted tools that can be used to develop applications software
for the desktop, consumer electronics and embedded systems markets."

"Metrowerks is a valued partner of Apple Computer and CodeWarrior was
instrumental in our successful transition from 68K to PowerPC." said Ellen
Hancock, Executive Vice President and Chief Technical Officer of Apple
Computer. "We are working closely with Metrowerks to ensure a cohesive set
of software development tools that span from MacOS 7.x to Apple's Next
generation OS. One of Apple's highest priorities in the deployment of our
Next generation OS is that CodeWarrior users can move their applications as
quickly and efficiently as possible. We're pleased that Metrowerks will
provide these new tools as part of their regular CodeWarrior subscription."
