ALADDIN SYSTEMS’ STUFFIT ENGINE SDK GETS AN UPDATE TO BOOST PERFORMANCE AND
ALLOW DEVELOPERS TO USE THE NEW 5.0 COMPRESSION STANDARD IN THEIR SOFTWARE

The StuffIt Engine 5.0 SDK Includes The StuffIt Compression And
Decompression Standard To Reduce Installer Size, Fit Developers
Needs, And Increase Benefits To Customers

Watsonville, CA- February 26, 1999 – Aladdin Systems, Inc., developer
and publisher of the worldwide Macintosh compression standard,
StuffIt(r), today announced the StuffIt Engine Software Developer Kit
(SDK) 5.0 for Macintosh is now available. The StuffIt Engine gives
third party software built-in support for StuffIt archives (.sit),
the Macintosh standard for archiving and compression.

By licensing the StuffIt Engine, a developer’s product can easily
create the new StuffIt 5.0 archives (.sit), Self-Extracting archives
(.sea), and encrypted archives among other formats. The StuffIt
Engine consists of a series of code resources that give users access
to standard StuffIt archival compression and decompression.

“As an industry leader it is important for Aladdin to continue to
develop new and better technology,” said Darryl Lovato, CTO.
“Creating the best architecture for Macintosh developers is
critically important and a big focus for us and the technology that
we introduce. Innovative leaders continuously push the boundaries to
improve their products transparently so the customer doesn’t even
notice a difference in how they use the product- that’s what we’ve
done with StuffIt.”

New StuffIt Engine Features and Enhancements:

*Now Multi-Lingual, all strings are stored in Unicode, lending files to
