SumTotal and Adobe Provide New Integrated Learning Solution

MOUNTAIN VIEW, Calif. – August 9, 2006 – SumTotal® Systems, Inc. (Nasdaq: SUMT), the largest provider of talent, learning and business performance technologies and services, and Adobe Systems Incorporated have integrated Adobe’s Macromedia® Breeze® Meeting software with SumTotal’s Enterprise Suite. Adobe also signed an agreement with SumTotal to make the Mountain View, Calif.-based firm an official reseller of Breeze, a collaborative web communication system.

With Breeze, employees can deliver multimedia content via virtual classrooms, training courses and online presentations. Companies can deploy Breeze using the ubiquitous Macromedia Flash® Player, which is already installed on more than 98 percent of browsers worldwide. Because users do not have to download software to launch Breeze, they can engage instantly with rich multimedia content. The SumTotal Enterprise Suite – an award-winning software platform – is a fulcrum for launching and managing online learning that aligns employees’ goals with an employer’s business aims. Together, the solutions should give employers large and small a hub for enabling online learning as well as capturing mission-critical knowledge.

“Adobe® Acrobat®, Flash, Dreamweaver® and Captivate™ are integral to the work our global network of clients does each day,” said Jon Ciampi, vice president of marketing for SumTotal. “With the addition of Breeze Meeting to our software suite, we can offer our clients unrivaled support for rich media through virtual classrooms and on-demand presentations."

SumTotal’s suite is among a select few learning management platforms that can simultaneously manage virtual classroom sessions from different vendors; this gives SumTotal’s clients even greater choice, flexibility and freedom in picking a solution for online collaboration.

“The combination of SumTotal’s industry-leading technology and Adobe Macromedia Breeze Meeting will give our customers a powerful new option for end-to-end learning solutions,” said Kevin M. Lynch, vice president of product marketing, Knowledge Worker Business Unit, Adobe. “Our partnership with SumTotal will give learning and development professionals a single, integrated learning-management and virtual classroom solution that is comprehensive and easy to use, at a low cost of ownership.”
