Mac Users Gain Performance, Security and Flexibility with Latest Upgrade

December 2, 2003 (Arlington, VA) - Group Logic, Inc. announced today the

Enterprise software for Mac OS X. Group Logic is the leading developer of
network workflow software products used throughout the print media and
graphic arts industry. Its enhanced version of MassTransit provides a
valuable new platform for mission critical file transfers by combining the
power of Apple's UNIX-based Mac OS X operating system with the advanced

MassTransit 4.2 takes advantage of the major enhancements of the Mac OS X
platform to create a more powerful tool for customers. Fully compatible
with the Mac OS X environment, MassTransit Version 4.2 provides an
integrated workflow solution that delivers:

- Superior performance, stability and reliability of MassTransit servers
based on the rock-solid, UNIX-based underpinnings of Mac OS X.

- Powerful new options for hosting MassTransit Enterprise's unique, web
file transfer workflows.

- Integrated security for web-based file transfer workflows.

- Enhanced flexibility in designing file transfer system architectures
through Mac OS X's networking enhancements.

"The Mac platform is extremely important to our customers in the graphic
arts marketplace," explains Andy Lewis, VP of Sales and Marketing at Group
Logic. "The stability, reliability and performance of Mac OS X make it an
excellent platform for mission-critical server software packages such as
our MassTransit Enterprise product."

MassTransit is the file transfer solution of choice among businesses that
buy or provide graphic arts and printing services, including corporations,
publishers, printers, prepress companies, and advertising agencies. In
North America, 11 of the top 15 printers use MassTransit for transferring
files between plants as well as to and from customer sites. Since its
inception in 1988, Group Logic has focused on Mac related products and the
company remains strongly committed to Apple and the Mac platform.
