FOR IMMEDIATE RELEASE

ANNOUNCING RETROSPECT 4.2 FOR MACINTOSH

Free upgrade of award-winning backup software includes new cross-platform
client license support and advanced networking features

ORINDA, CA–September 14, 1999–Dantz Development Corporation announced
today continued support for the Macintosh(R) by releasing a free upgrade to
the popular Retrospect(R) backup software. Retrospect 4.2 adds flexible
application-based client licensing that allows any Macintosh running
Retrospect to easily back up both Macintosh and Windows(R) computers across
the network. Administrators are no longer required to purchase separate
Retrospect Client packs for each platform. Other new features include
advanced networking to back up computers across routers, HTML-based help,
and an upgraded disaster recovery CD.

Retrospect 4.2 is a free upgrade to registered users of version 4.1 and
will be available via the Dantz Online Store starting October 1, 1999.

PRODUCT LINE CHANGES

With the release of version 4.2, the names of the Retrospect products for
Macintosh have changed. Retrospect becomes Retrospect Desktop Backup, and
Retrospect Network Backup Kit becomes Retrospect Workgroup Backup. In
addition to the name change, Retrospect Workgroup Backup includes twenty
(20) cross-platform clients, a significant increase from the ten (10)
previously included Macintosh only clients. Pricing remains unchanged for
all products.

APPLICATION-BASED, CROSS-PLATFORM CLIENT LICENSES

Retrospect 4.2 eases the task of client administration in workgroups by
shifting from individual client licenses to flexible application-based
licenses. The backup administrator simply enters one or more client license
codes into the Retrospect application. The administrator can then add
networked Macintosh or Windows clients, up to the amount allowed by the
license. Retrospect keeps track of all client licenses, significantly
decreasing administration tasks.

New Retrospect Client packs contain software for both Macintosh and Windows
platforms, providing users with more flexibility for heterogeneous
networks. Previously, separate packs were required for each platform.
Retrospect 4.2 also allows any previously purchased Retrospect Client codes
to be used with either Macintosh or Windows clients, regardless of the
Client package originally purchased.

ADVANCED NETWORKING

Retrospect 4.2’s advanced networking features make it easy to back up any
computer on the network. Administrators simply define IP address ranges,
and Retrospect ensures clients located within those subnets are included in
the backup. Organizations that use DHCP address allocation can now reliably
back up client computers, even across one or more routers.

ADDITIONAL NEW RETROSPECT 4.2 FEATURES

o HTML Help: Retrospect’s online help system is now easier to navigate and
search. Hypertext links allow users to quickly access information within
the program or on the Dantz website.

o Updated Disaster Recovery CD: The new Retrospect 4.2 CD boots all
currently shipping Power Macintosh computers, including iMacs, “blue and
white” G3s, and “bronze” G3 PowerBooks. The CD boots Mac OS 8.6 and
includes the latest versions of Apple’s Disk First Aid and Drive Setup
utilities, offering users the fastest method of repairing and restoring a
hard drive.

o DES Encryption: Retrospect 4.2 ships with the US government standard DES
encryption. Previously unavailable internationally, this robust 56-bit
encryption is now standard with all versions of Retrospect.

UPGRADES AND PRICING

Registered owners of Retrospect version 4.1 are entitled to a free upgrade
that can be downloaded from www.dantz.com beginning October 1, 1999. For
customers who wish to receive the new Mac OS 8.6 bootable disaster recovery
CD, a small handling fee will apply.
