Date: 09/04/2007

Company: ISE Limited

Segment: Systems, Transportation

SAN DIEGO, CA, September 4, 2007 — ISE Corporation recently received an order for its ThunderVoltTM gasoline hybrid-electric drive systems to power six NABI (North American Bus Industries) buses in the Los Angeles, CA area. Funded by the Advanced Transit Vehicle Consortium (ATVC), the hybrid buses will be operated by the Los Angeles County Metropolitan Transportation Authority (LA Metro).

The NABI hybrid buses will feature ISE’s ThunderVoltTM gasoline hybrid-electric drive system, which was certified as an “alternative fuel” system by the California Air Resources Board (CARB) in November 2003. Over 100 hybrid buses utilizing ISE’s ThunderVoltTM gasoline hybrid-electric drive system are already in revenue service in various California cities, including Long Beach, Orange County, Norwalk, Montebello, Gardena, San Bernardino, and Fresno. ISE will supply the six ThunderVoltTM hybrid-electric drive systems to NABI with Siemens electric drive components, advanced ultracapacitor energy storage system, and ISE proprietary hybrid controls.

“We are pleased to be a part of LA Metro’s environmental path, showcasing NABI’s 42-foot low-floor, stylized transit bus,” said Bob Shaughnessy, President and CEO of NABI. “The reliability, enhanced passenger and driver accommodations, combined with the powerful ISE series hybrid drive train exemplifies our technologically-advanced hybrid buses.”

“ISE is proud of its role in delivering clean and efficient technology to LA Metro,” said David Mazaika, ISE’s President and CEO. “These buses will deliver lower emissions while also improving vehicle performance, reducing brake maintenance and eliminating transmission maintenance.”

“We are looking for these buses to push the technology envelope for our industry,” said John Drayton, LA Metro’s Vehicle Technology Manager. “With their increased generating capacity and ultra-capacitors for energy storage, these buses should be a pretty significant leap forward for hybrid transit vehicles.”
