Quantum Acquires Regency Conversions, Inc.

IRVINE, Calif., Feb. 10, 2006 -- Quantum Fuel Systems Technologies Worldwide, Inc., today announced that its subsidiary, Tecstar Automotive Group, has acquired Texas based Regency Conversions, Inc., a special vehicle manufacturer, for 1.8 million shares of Quantum common stock and $3.3 million in cash. Regency, is one of the largest vehicle converters in North America, producing approximately 5000 vehicles annually which are sold through 250 automobile dealerships throughout the continental U.S. Regency's unaudited revenues for calendar year 2005 were in excess of $40 million.

Regency will supplement Tecstar's current second stage vehicle manufacturing and aftermarket parts business by offering additional distribution channels directly to automotive dealers, and significantly broadens Tecstar's customer base beyond OEMs. As a result of the acquisition, the integration of Tecstar's manufacturing and engineering expertise into Regency will enable Regency to further improve its product offerings and enter additional new vehicle markets requiring OEM level engineering and validation.

Alan Niedzwiecki, President and CEO said, "We are honored to have Regency join the Quantum-Tecstar team and participate with us in our aggressive plan to accelerate the growth of our business. The acquisition is the next step in a series of opportunities to build near-term, high-margin, revenue-enhancing business for Quantum. These opportunities are the result of our initiatives to utilize our competencies in limited volume production and advanced technology for near-term revenue growth. Our unique capabilities and experience in turning concepts into limited volume production is in growing demand worldwide for applications ranging from hybrid electric vehicles, to alternative fuel vehicles, including natural gas, propane, and hydrogen, to fuel cell vehicles, as well as for mainstream automotive and ultimate high- performance specialty vehicles."
