Key Business Metrics:

  In-house battery electronics design capability   5year/$40M United States Military contract to establish 30 year

supply of materials and cells for satellite and military applications   Strong Li ion battery IP Position with over 60 chemistry, cell and

battery patents issued and numerous patents pending   Operations contained within 52,000 sq ft production facility in Los

Angeles, CA, with an option to expand to 200,000 sq ft of contiguous manufacturing space

  Certifications include ISO 9001:2000, AS9100B, and ISO 13485:2003

  Diversified across medical, military, vehicle and aerospace markets, 104 employees. More than 60,000 cells produced annually

  Quallion is fiscally sound with cash reserves and profitable. Quallion is not reliant on the external credit markets for expanding production

  Unique knowledge of Li ion chemistry as technology is rooted in Material science

  Active large Li ion battery programs include: USG Title III, Aircraft Retrofit, NASA Orion program (new space shuttle), Blackhawk Helicopter Retrofit, APUs for HMMWV, UAVs, Launcher Vehicle Batteries, Satellite Systems, USAF X-51 Scramjet

Quallion 18650 HP

  Electrical Characteristics –  Nominal Capacity = 900 mAh –  Operating Range = -40°C to +71°C –  Chemistry = NCA/MCMB

  Physical Characteristics –  Diameter = 18.1 mm –  Height = 65.4 mm –  Volume = 66.7 cc –  Weight = 39 g

  Heritage Materials –  Active materials are the same as Quallion

SATELLITE cells –  USG T3 program enables Quallion to

produce Cathode NCA and Anode MCMB in-house by 2012
