Human Resources: SumTotal Wins $1.5 Million Contract with U.S. Army Defense Ammunition Center

    MOUNTAIN VIEW, Calif.--Nov. 1, 2006--SumTotal(R) Systems
(Nasdaq:SUMT), the largest provider of talent and learning solutions,
received a $1.5-million subcontract during its third quarter for
continued support of the U.S. Army Defense Ammunition Center's (DAC)
current and future global training initiatives. SumTotal will provide
hosting operations to support the DAC's migration to an upgraded
version of the SumTotal learning management system (LMS) and learning
content management system (LCMS). This upgrade will also expand the
capacity of DAC's student population to well over 100,000 users
worldwide. SumTotal serves as a sub-contractor to SI International
(Nasdaq:SINT) of Reston Va., a provider of information technology and
network solutions, on this award.

    The McAlester, Okla.-based DAC will use SumTotal Enterprise
Suite(TM) Version 7.2, an integrated LMS/LCMS software platform, to
instruct U.S. military personnel on the proper handling of ammunition,
explosives safety and logistics support to Department of Defense
military and civilian personnel, other federal agencies and military
students from allied nations. SumTotal's LMS delivers online education
via the Internet, and its LCMS helps course designers rapidly create
an array of content, including simulations.

    "The LMS can prepare students for face-to-face training, and also
provide a lifeline to their lessons after they get to the field," said
William S. Scott, distance-learning supervisor -- DAC Training
Directorate. "This helps keep students stay connected to their newly
acquired skills, and it increases retention. This is crucial to
mission readiness and success."

    The primary focus of the DAC is to support ammunition readiness
for the 21st century war-fighter as well as supporting the global war
on terrorism. With the support of SI International and SumTotal, the
DAC currently provides web-based training to over 25,000 students on
an annual basis.

    "The Defense Ammunition Center is a leader in constructing
innovative solutions that are increasing the readiness of the arms,
ammunition and logistics community." said James Gill, director of
Government Solutions for SumTotal. "It is a privilege for us to be
part of this mission-critical project, and we are honored that DAC and
SI International selected us as a partner to continue this important
work in support of our war-fighters."

    In 2004, SI International won an initial contract to provide an
enterprise-wide learning solution used to evaluate DAC training
courses, create web-based training development processes, develop a
long term Training Plan, and implement the SumTotal LMS/LCMS. Under
the new contract, of which SumTotal is a sub-contractor, SI
International will provide continued support for previous tasks,
implementation of an Enterprise Resource Planning training solution,
and design and development of an Arms, Ammunition and Explosives
(AA&E) web portal. The contract was awarded under the Millennia Lite
Functional Area 2 GSA contract vehicle and has a one-year base period
with four one-year option periods. The contract value is approximately
$9 million, if all options are exercised.
