Human Resources: World's Largest Business Federation Will Manage Learning and Talent with SumTotal

    MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--April 30, 2007--The U.S.
Chamber of Commerce selected SumTotal(R) Systems, Inc. (NASDAQ:SUMT),
a global provider of talent and learning management solutions, to
build an online university for approximately 500 Chamber employees
across the United States. The online university will be an easily
accessible portal for employees to find information related to
professional development, tap into best practices and obtain
compliance training.

    To build its online university, the Washington, D.C.-based
organization selected SumTotal's ResultsOnDemand(TM) platform, which
is SumTotal's software-as-a-service (SaaS) model for analyzing
employee performance and delivering learning over the Internet.

    Among the first initiatives for the online university will be
delivering instruction aimed at the Chamber's membership-development
team, which focuses, in part, on selling the value of a Chamber
membership to small, medium and large businesses.

    To supplement training for its membership development team, the
Chamber will also use the SumTotal platform to put instruction online
so team members can continually refer back to their classes and access
the most up-to-date curriculum.
