                                 Engine Control Systems Ltd.
                                AZ Purifier and AZ Purimuffier

Pursuant to the authority vested in the Air Resources Board by Part 5, Division 26 of the
Health and Safety Code and Sections 38390, 38391, and 38395 of the Vehicle Code; and

Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the
Health and Safety Code and Executive Order G—02—003;

IT IS ORDERED AND RESOLVED: That installation of the AZ Purifier and AZ Purimuffier
devices, manufactured by Engine Control Systems Ltd. of 165 Pony Drive, Newmarket,
Ontario, Canada L3Y 7V1, has been found not to reduce the effectiveness of the applicable
engine emission control system, and therefore, the AZ Purifier and AZ Purimuffler devices
are exempt from the prohibitions in Sections 38390 and 38391 of the Vehicle Code for
installation on the off—road compression—ignition engines listed below. This exemption is
limited to engines certified to California‘s Tier 1 exhaust emission standards. This
exemption is also limited to engines used in equipment used at the ports, railway yards, and
intermodal operation such as a yard tractor, lift truck, top pick, side pick, and a gantry crane.



              1996—2002             Case                         3.9/5.9/8.3

The AZ Purifier and AZ Purimuffler exempted under this Executive Order can be installed
on engines operated using standard California diesel with a maximum sulfur content of 500
parts per million by weight (ppmw), ultra low sulfur diesel (ULSD) with a maximum sulfur
content of 15 ppmw, or PuriNOx water emulsion fuel based on either standard California
diesel or ULSD. The AZ Purifier and AZ Purimuffler devices exempted under this Executive
Order are identified in Attachment A.

This exemption is based on emission tests conducted by Engine Control Systems Ltd. with
the AZ Purimuffler. Test data showed that the AZ Purimuffler has no adverse impact on
engine emissions. The same emissions impact is expected when the AZ Purifier and AZ
 Purimuffler are installed on any of the engines listed above.

 This Executive Orderis valid provided that installation instructions for the AZ Purifier and AZ
 Purimuffler do not recommend tuning the engines to specifications different from those of
 the engine manufacturer.

Purifier and AZ Purimuffler may have on any warranty either expressed or implied by the           t
engine manufacturer.                                                                              :
