CLEAN DIESEL SIGNS LETTER OF INTENT
PAGE 2-2-2

Japan recently announced plans to fit new and existing diesel powered vehicles
with filters to reduce particulates and has also called for further reductions
in NOx emissions. The Tokyo Metropolitan Government called for retrofit
particulate control programs on over 900,000 vehicles operating within the city
limits starting in 2002-2003. Both the ARIS technology and the Platinum Plus FBC
have been demonstrated to provide reductions in diesel NOx and particulate
emissions in excess of 85 percent with current sulfur fuels.
