QUANTUM Awarded Contract to Develop Hydrogen Storage System

    IRVINE, Calif., March 22 QUANTUM Technologies, Inc., a
wholly owned subsidiary of IMPCO Technologies, Inc. today
announced that Thor Industries , the largest mid-size bus
manufacturer in the U.S., will use a QUANTUM hydrogen storage tank system in
its new fuel cell bus.
    
    QUANTUM will use its advanced composite Type IV hydrogen storage tank that
is uniquely designed and manufactured with a single end boss, one-piece
seamless liner and a carbon composite over-wrap.  The QUANTUM Type IV hydrogen
storage tank is tested and validated to all regulations and standards,
including OEM-specific validation tests.  QUANTUM's hydrogen storage tanks
will be mounted on the roof of the bus.

    The Thor fuel cell bus will use a Thunderpower (r) hybrid-electric drive
train developed by ISE Research Corporation, San Diego, CA in a 30' low-floor
bus built by Thor's subsidiary, Eldorado National.  ISE will perform the
system integration, to include the QUANTUM hydrogen storage tank subsystem.
The fuel cell power plant is being developed by International Fuel Cells
(IFC), a division of United Technologies.

    Thor has been a market leader in the development of alternative propulsion
systems for bus applications.  IFC is the world's leading manufacturer of fuel
cell power plants.  ISE is a leading developer of hybrid drive trains for
heavy-duty vehicles.

    "This event marks QUANTUM's entry into the fuel cell bus market and
underscores QUANTUM's successful focus on enabling technologies for
alternative propulsion and energy," said Syed Hussain, President & CEO of
QUANTUM."
