Amerigon Announces Agreement in Principle With Visteon to Develop Array of Climate Control Automotive Products

Environmentally Friendly Spot Heating/Cooling Units among First Products Targeted; Advances in Thermoelectric Technology to Be Employed

DEARBORN, Mich., June 18 -- Amerigon Inc. today announced that it signed an agreement in principle with Visteon Corporation to develop an array of environmentally friendly heating and cooling products for the automotive industry. The agreement couples Amerigon's subsidiary, BSST's proprietary efficient thermoelectric device (TED) technology with Visteon's world-class climate control and vehicle interior systems capabilities.

Amerigon Chairman Oscar (Bud) Marx said, "We believe that TED-based climate control systems could revolutionize automotive climate control in the next decade. We are building on the strengths of the two companies, combining Amerigon's proprietary TED technology and Visteon's systems capability, global customer base and strong market position in climate control, vehicle interiors and electronics. Together we can provide the platform to develop a broad and exciting array of TED-based products."

BSST's TED-based technology was developed under the guidance of Amerigon Vice Chairman Lon E. Bell, Ph.D., who is also President of BSST. "TED-based products are extremely environmentally friendly and, with few moving parts, exhibit outstanding reliability," Bell said.

"As we at BSST make thermoelectrics much more efficient, the range of product opportunities opens up dramatically," Bell said. "BSST has already developed breakthrough technology that doubles the efficiency of the present thermoelectric devices for air conditioning and related applications. These advances, along with emerging TED materials improvements, which will further increase efficiency, should provide the basis for a variety of products not only within the automotive industry, but in many other areas including communications, electronics, healthcare, personal comfort and defense."

Amerigon's value enhancing Climate Control Seat(TM) (CCS(TM)) system, which the Company will continue to exclusively market to automotive and seat manufacturers worldwide, uses a proprietary TED-based heat pump and is the industry's only actively heated and cooled seat system providing individual driver and passenger comfort in virtually all climatic conditions. Four major automotive manufacturers have chosen CCS for use in 12 vehicles, and more than 500,000 seat systems have been shipped.
