Dow Kokam and PVI Partner in Deployment of First Fully Electric Refuse Trucks

Dow Kokam Batteries and PVI Electric Powertrain Eliminate 130 tons of CO2 Per Truck Per Year

LYON, France, December 3, 2010 - Dow Kokam and PVI announced today an agreement to supply advanced lithium
polymer battery technology to power the first ever fully electric refuse
trucks. The electric truck and its battery system, which will be produced and
assembled in France, was unveiled today at Pollutec 2010 by PVI and its
partner SITA, a subsidiary of Suez Environnement, alongside examples of Dow
Kokam's battery system technology. The 26-ton, zero-emission truck will
eliminate 130 tons of CO2 per truck per year.

"Today's unveiling of our first fully electric refuse truck, arguably the
largest electric truck on the market, is a great accomplishment in vehicle
electrification because these trucks place unique and high demands on their
operating systems due to specific designs for urban cleaning," said Michel
Bouton, the Chief Executive Officer of PVI. "The ability to introduce a
completely electric truck of this size that doesn't sacrifice performance or
power is due to PVI's extensive history in vehicle electrification and the
selection of Dow Kokam's advanced lithium polymer battery technology, which
provides ready solutions to meet the high performance needs of working trucks
operating daily in urban environments."

Electrification of all powertrain elements of the trucks and the
mechanical elements for collecting refuse bins allow for significantly
reduced noise pollution, zero local emissions and no idling during inactive
periods. PVI designed the vehicles to achieve comparable performance to
conventional refuse trucks with a deadheading speed that can reach 70
kilometers per hour at full payload, and the added benefit of 100 percent
starting torque. Drivers will be able to collect a payload of 16-tons in two
rounds of service. The modular plug-in pack was also designed to be
interchangeable or accommodate a partial recharge between two daily service
rounds, thus doubling performance capabilities. Thanks to PVI's integrated
gearbox kinematics, the truck will be able to climb steep inclines with a
full payload without impeding urban traffic.

Dow Kokam will supply each truck with a complete battery system
containing five strings of seven battery packs (equivalent to 250 kilowatt
hours), power management capability and the complete battery management
system. These battery systems are assembled in France at the production
facility of Le Bouchet (Vert-le-Petit, Essonne).

PVI selected Dow Kokam's large-format, prismatic battery system because
of its 10 year usable life and superior energy density, (140 watt hours per
kilogram of specific energy), while maintaining exceptional energy/power
balance, (140 watt peak power). The advanced liquid cooled lithium ion
battery packs and exceptional thermal management of the Dow Kokam system
enable the vehicles to be used in very diverse operating temperatures from
the far northern areas of Europe to the very south.

Dow Kokam batteries bring the reliability of more than 10 years of proven
performance in demanding applications. The system integration capabilities
have been proven in more than 1 million kilometers of rigorous, on-the-road
testing. Dow Kokam technology has been adopted as the primary source of
energy for high performance equipment in industries ranging from
transportation, marine, aerospace, defense and high-end industrial products.

"This achievement demonstrates that real advanced battery solutions exist
for the commercial and fleet industry today," said Jean-Francois Herchin,
Vice President of Dow Kokam. "PVI has chosen Dow Kokam technology to achieve
the highest level of usable energy while maintaining the power and
acceleration necessary to move its massive 26-ton truck."

PVI's vehicle, propelled by Dow Kokam battery technology, is the first
ever fully electric refuse truck offering the same performance levels as
conventional utility vehicles. Its first deployment by SITA Ile de France is
expected to be in Courbevoie, just outside of Paris, by early 2011; and a
fleet of 11 vehicles will be operating daily before the end of 2011.
