    MOUNTAIN VIEW, Calif.--Dec. 4, 2006--Military Training Technology
magazine and Kerrigan Media International have placed SumTotal(R)
Systems, Inc. (NASDAQ: SUMT) on the Military Training Technology 2006
Top 100 List for the second consecutive year. The list includes
companies that have made significant contributions to the military
training industry. SumTotal makes software that not only delivers and
manages training over the Internet but also automates employee
performance appraisals.

    Selection criteria for this year's list included customer
feedback, innovation and volume of military sales. Military Training
Technology magazine also awarded SumTotal an orange ribbon for "Best
Programs," which denotes a company that has been involved with or
spearheaded programs that are revolutionizing training for the
military. According to the magazine, SumTotal "received contracts this
year from U.S. Northern Command, Defense Security Service, U.S. Army
Military Intelligence School, Defense Acquisition University and
Defense Ammunition Center."

    "We believe our mission is giving warfighters a range of
cutting-edge training and development tools that will help them
complete their mission anywhere, anyplace and anytime," said Jim Gill,
SumTotal Systems' director of Government Solutions. "Earning this
ribbon and place on the Top 100 confirms we've kept our focus upon our
mission and our expertise."

    The magazine's editorial board and panel of independent experts
also noted SumTotal's acquisition of MindSolve Technologies Inc., a
privately held provider of performance management software, in
describing why SumTotal earned a place on this year's Top 100 list.
