ISE Corporation, Leading Manufacturer of Hybrid-Electric Drive Systems, Announces $25 million Series B Financing

POWAY, CA; WASHINGTON, DC, March 8, 2006 — ISE Corporation ("ISE") and NGP Energy Technology Partners L.P. ("NGP ETP") today announced a $25 million equity investment in ISE, a leading supplier of advanced electric and hybrid-electric drive systems for heavy-duty buses, trucks, airport equipment, and specialized military vehicles. In addition to NGP ETP, investors in the ISE Series B financing include Rockport Capital Partners and Third Avenue Management. This $25 million Series B preferred stock financing is one of the most significant investments to date in a hybrid-electric technology company.

The financing follows ISE's achievement of several milestones including ISE's successful delivery of 100 hybrid-electric drive systems in 2005, which accumulated a total of 1.5 million miles during their first year of revenue service in transit buses across California. ISE's ThunderVolt® hybrid-electric drive systems are based on a "series" hybrid design that mates a power source (such as an engine/generator or fuel cell) with energy storage (batteries or ultracapacitors) to power a set of electric motors which propel the vehicle. ISE's ThunderCAN® proprietary control software optimizes power management to provide significantly higher mileage and lower emissions while providing excellent performance. ISE's broad product offering includes hybrid systems fueled by gasoline, diesel, natural gas, and hydrogen, including fuel cell-based systems, and are targeted at transit buses, delivery and trash trucks, military vehicles, and school buses.

"These funds will be used to increase our production capacity to meet the rapidly expanding demand and provides ISE the financial strength to become a truly global player in the hybrid transportation market," stated David Mazaika, ISE co-founder and CEO. "It also will enable expanded R&D to ensure ISE continues to offer the broadest product line in the industry, incorporating the most advanced technologies to produce the highest fuel efficiency, lowest emission heavy duty hybrid drive systems available."

"NGP Energy Technology Partners believes that the future of energy technology will be led by companies with strong management teams, disciplined business strategies, and compelling commercial products. ISE has all these and is poised to take advantage of the benefits hybrid technologies will bring to the transit bus, heavy duty truck, and military markets," said Philip J. Deutch, Managing Partner of NGP ETP. Alexander "Hap" Ellis, General Partner of Rockport Capital, added, "ISE's technology is fuel flexible, working with gasoline, diesel, natural gas, and fuel cell powered vehicles. No other technology company has these capabilities." Martin J. Whitman, Founder and Co-Chief Investment Officer of Third Avenue Funds and an extremely well-known value investor, stated, "We are impressed by both ISE's management and products and strongly believe in the prospects for ISE to be a leader in hybrid drive systems and alternative fuel technologies in the United States."

The $25 million Series B preferred stock investment led by NGP ETP follows a $6.7 million Series A preferred stock investment led by North Arrows LLC in 2004. "North Arrows and the Series A investors are pleased that other highly regarded investors recognize ISE's outstanding accomplishments to date and its future growth potential," said Steve Strait, Principal of North Arrows and Chairman of ISE. Added Strait, "We look forward to working together with our new partners to demonstrate to the heavy-duty vehicle market the low emissions, higher fuel efficiency, and outstanding reliability of ISE's drive systems."

ISE plans to use the proceeds from the financing to expand ISE's production capacity to five hundred hybrid drive systems per year and to provide the resources to market and support its hybrid drive products on a global scale.

First Albany Capital served as ISE's placement agent and financial advisor on the transaction.
