ALADDIN SYSTEMS ANNOUNCES STUFFIT DELUXE OS 8 UPGRADE POLICY

Registered StuffIt Deluxe 4.0 Users Who Have Purchased StuffIt Deluxe After
July 26, 1997, Qualify For Free StuffIt 4.5 Upgrade

Watsonville, CA – August 27, 1997 – Aladdin Systems today announced that
StuffIt Deluxe 4.0 registered users (who purchased 4.0 after July 26,
1997) will be able to upgrade to version 4.5 for free (plus shipping fee).
Significant enhancements of StuffIt Deluxe 4.5 will include Mac OS 8
(Tempo) compatibility, support for more expansion formats like MIME/Base64,
encrypted ZIP, and LHA expansion, additional email program support and
Private File encrypted file support.

StuffIt Deluxe works in the Finder at a lower level than most applications,
and a lot has changed in the OS 8 Finder. Currently, the StuffIt Deluxe 4.0
core functionality is compatible, but the package contains three
incompatible elements: StuffIt Browser, StuffIt SpaceSaver, and Magic
Menu. These components will be compatible with OS 8 in StuffIt Deluxe 4.5.

Aladdin expects to release StuffIt Deluxe 4.5 within the next 90 days.
