Motorola, Inc (NYSE: MOT) and Amerigon Inc. (Nasdaq: ARGNA) today announced they have entered into a non-binding memorandum of understanding to develop a new generation of electronic control modules (ECMs).

Under terms of the memorandum of understanding, the companies intend to negotiate and enter into a definitive non-exclusive agreement to use Amerigon's proprietary Climate Control Seat(TM) system (CCS(TM)) and Motorola's manufacturing expertise to jointly develop ECMs. ECMs are used to manage the thermal outputs of the CCS system.

The Amerigon CCS system is currently available as an option on the 2000 model year Lincoln Navigator Sports Utility Vehicle and is the only product on the market today that makes it possible for both the driver and front seat passenger of a vehicle to individually and actively control the warming and/or cooling of their respective seat for year-round comfort.

"We believe that the Amerigon CCS is a breakthrough automotive technology with great potential," said Michael Cops, Vice President and Director of Motorola's Automotive and Industrial Electronics Group (AIEG). "Our goal is to team with companies like Amerigon where Motorola's design, quality and manufacturing resources combined with Amerigon's entrepreneurial innovation and marketing skill can produce high volume products that have the potential to capture strong market positions."

"Motorola is known globally for supplying world-class electronic products that deliver top performance to automotive customers," said Amerigon President and CEO Richard A. Weisbart. "By joining forces with Motorola for the development and manufacture of our new generation of ECMs for CCS, we will gain significant leverage in the market and have a dependable, high-volume supply of product of the best-possible quality."

According to Weisbart, each company intends to be responsible for funding its own costs such as engineering, technical resources and capital investment.

The Ford Motor Co. has agreed to use Amerigon's proprietary CCS system exclusively for heated and cooled or heated and ventilated seats for a period of five years. Amerigon continues to market CCS to other vehicle manufacturers and seat suppliers worldwide. The Irwindale, Calif.-based company is currently in discussions with more than 20 other seat and vehicle manufacturers in the U.S. and internationally.
