      New Plug-In Hybrid (PHEV) Based on the Prius Introduced

      Valence Technology, a developer of large-format Lithium-ion rechargeable
      batteries, and EnergyCS, a developer of integration control systems, are
      introducing a plug-in hybrid (PHEV) concept car based on a 2004 Toyota

      To be shown at the 21st Worldwide International Battery, Hybrid and Fuel
      Cell Electric Vehicle Symposium & Exhibition (EVS 21) in Monaco next week,
      the PHEV uses Valence's phosphate-based Lithium-ion battery system.

      As designed and programmed, the Prius has a driver-selectable EV (electric
      vehicle) drive mode. When toggled, EV mode turns off the combustion engine
      and the Prius functions as an all electric vehicle-particularly good for
      starting up and neighborhood travel. The default EV driving mode can be used
      for about one mile with a maximum speed of about 34 mph. EV mode is not
      currently activated for Priuses bound for the US, although it is on models
      in Japan and Asia.

      In its stock EV mode, however, the Prius is not very satisfying. The battery
      pack wasn't selected with extended EV operation in mind, and, more
      critically, the vehicle can't plug in to recharge the batteries. Staying far
      away from a plug-in was part of Toyota's planning, and remains part of the
      marketing for the car. Toyota took special care especially during the roll
      out of this version of the Prius to point out that it did NOT plug in.

      The California Cars Initiative (CalCars), a non-profit startup dedicated to
      jump-starting the market for plug-in hybrids (PHEV), has also been working
      on building a prototype Prius (the Prius+) capable of functioning as a
      plug-in hybrid and running in full EV (electric vehicle) mode for longer
      distances than possible with the original Toyota equipment.

      With a more capable battery pack extending EV operation of the car, the
      Valence/EnergyCS prototype delivers up to 180 mpg for an average commute of
      50-60 miles per day. The vehicle will also be part of the Monte-Carlo Fuel
      Cell & Hybrid Rallye on April 2.

      The Valence batteries use a phosphate-based cathode material rather than the
      cobalt-oxide used in traditional Li-ion cells. Phosphates are stable in
      overcharge or short circuit conditions and have the ability to withstand
      high temperatures without decomposing. When abuse does occur, phosphates are
      not prone to thermal runaway and will not burn.

      In addition to being more stable and safer, the the phosphate-based
      batteries offer better longevity and discharge than their cobalt-oxide

      New Concept Car Developed With EnergyCS Offers Dramatically Better Gas
      Mileage and More Zero Emission Driving Than Existing Hybrids

      MONACO & AUSTIN, Texas--(BUSINESS WIRE)--March 29, 2005-- At the 21st
      Worldwide International Battery, Hybrid and Fuel Cell Electric Vehicle
      Symposium & Exhibition (EVS 21) being held next week, Valence Technology
      Inc. (Nasdaq:VLNC - News), a leader in the development of large-format
      Lithium-ion rechargeable batteries, and EnergyCS, developers of integration
      control systems, will showcase a new concept plug-in hybrid electric

      Powered by the Valence U-Charge(TM) Power System, the plug-in hybrid
      electric vehicle (PHEV) is a fully functional concept car based on a 2004
      Toyota Prius. Because the Valence battery offers much more energy than
      batteries traditionally used in hybrid vehicles, it allows significant
      amounts of zero-emission driving with the concept PHEV. With a fuel
      efficiency that can reach up to 180 miles per gallon for an average commute
      of 50-60 miles per day, the PHEV has superior gas mileage, which means fewer
      trips to the gas station. Using the U-Charge system, the PHEV offers the
      best of both worlds: zero-emission electric mode (up to 33 mi/h, 53 km/h)
      and an efficient gas motor for long trips.

      Valence will exhibit in EVS 21 Booth C128 and the Valence-EnergyCS PHEV will
      be on display at the Ride and Drive area throughout the EVS 21 show. The
      vehicle will also be part of the Rallye Monte-Carlo Fuel Cell & Hybrid on
      April 2.

      "Valence's phosphate-based Lithium-ion batteries have substantially higher
      energy density than competing batteries for hybrid electric vehicles. And,
      unlike other types of Lithium-ion batteries, our Saphion technology offers
      the longevity and safety needed for both hybrid and pure electric vehicles,"
      said Stephan Godevais, president and CEO of Valence Technology. "The
      Valence-EnergyCS plug-in hybrid vehicle is a breakthrough in the industry.
      It allows renewable energy to displace gasoline, reducing our reliance on
      fossil fuels, which is increasingly important given today's environment and
      economic concerns."

      The U-Charge battery system used in the Valence-EnergyCS PHEV is based on
      Valence's Saphion® technology, the only one like it on the market today. It
      replaces toxic heavy metals with phosphates, creating an energy storage
      battery that is chemically more stable, and therefore safer, than
      traditional oxide-based Lithium-ion batteries. Saphion technology's
      chemistry yields a battery that is not only environmentally friendly, but
      requires virtually no maintenance and offers long life and low total cost of
