Apple Turns Over Development of Macintosh Common Lisp to Digitool, Inc.

Digitool to Market and Support Macintosh Common Lisp, Provide Native Power
Macintosh Version

Cupertino, California--November 10, 1994--As part of its program to
accelerate the availability of developer tools for the Power Macintosh,
and demonstrating its commitment to Macintosh Common Lisp (MCL) users,
Apple Computer, Inc. today announced that it has licensed its MCL
development software to Digitool, Inc. The purpose of the agreement is for
Digitool to take over future development of MCL. Digitool has agreed to
provide ongoing marketing and technical support for MCL, and to introduce
next year a Power Macintosh version of the software, which will generate
native PowerPC code.

Digitool also has agreed to continue further development of the version of
MCL for Macintosh systems based on the Motorola 680x0 processors. Apple
will continue to offer MCL through APDA, the company's source for
developer tools.

"This agreement underscores Apple's ongoing commitment to the developer
community to provide strong support for our developer tools and to allow
developers to move their code forward to new hardware platforms and OS
releases," commented Peter Christy, Apple's senior director of Developer
Products Engineering. "With this agreement, Apple and Digitool will be
working together to ensure a bright future for MCL on both the 680x0-based
Macintosh and Power Macintosh."

Apple now expects that developers who have programs based on MCL code will
be able to continue development efforts with the knowledge that their code
can be ported to the Power Macintosh. In addition, developers will benefit
by full support--and future enhancements--of the 680x0 version of MCL by
Digitool.

"Digitool is very pleased with this new MCL responsibility," said Hazem
Sayed, president and founder of Digitool. "MCL is in a league of its own
as an implementation of the Common Lisp standard and object system. It has
sold many Lisp users on the Macintosh and sold many Macintosh developers
on Lisp. Now, as well as with our future release of a Power Macintosh
native MCL, many of the large workstation-based Lisp systems developed in
academe, aerospace, telecommunications, military, finance and medicine
will find an unbeatable price/performance delivery platform."

Digitool, based in Cambridge, Massachusetts, is a new software company
formed by the principals of Paradigm Software, Incorporated, and staffed
by former employees of Apple's MCL development team. Digitool's MCL
development effort is partially funded by eleven corporate sponsors and
MCL customers including Apple Computer, Inc., Flavors Technology, Inc.,
KyTek, Inc., Lissys Ltd., and the University of Basel.

Product Summary

Common Lisp is an advanced programming language widely used in industry and
research. MCL is recognized as a premier implementation of Common Lisp on
personal computers with performance comparable to Lisp workstations. An
object-oriented dynamic language, MCL implements the ANSI Common Lisp
Object System (CLOS) and includes an incremental compiler and application
generator. MCL is ideally suited for quick application prototyping and
provides a delivery environment for intelligent applications as well as
high-level Macintosh interface access.

Availability and Pricing

MCL Version 2.0.1 is available for U.S. $495 through APDA, Apple's source
for development tools and related programming products. Pricing for future
versions will be announced upon product availability. Digitool also has
announced that it will provide current users with the ability to upgrade
to future versions at a reduced price. Site licenses for MCL are also
available from APDA.

APDA publishes the APDA Tools Catalog which describes hundreds of Apple and
third-party products. Developers should contact APDA for orders only and
