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 Purifilters, manufactured by
Engine Control Systems 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 Purifilters are exempt from the prohibitions in Sections 38390
and 38391 of the Vehicle Code for installation on 1996 through 2003 model—year off—road
compression—ignition engines of 20.0 liters or less displacement.

This Executive Order is only valid provided the engines meet the following operating
condition: the engine exhaust temperature is between 280 and 325 degrees Celsius for at
least 25 percent of the typical duty cycle.

The Purifilters 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 50 ppmw,
or PuriNOx water emulsion fuel based on standard California diesel or ULSD. The
Purifilters exempted under this Executive Order are identified in Attachment A.

This Executive Order is based on emission tests conducted by Engine Control Systems with
the Purifilter. Test data showed no adverse impact on engine emissions. The same
emissions impact is expected when the Purifilters are installed on any of the engines listed
above.            -

This Executive Order is valid provided that installation Instructions for the Purifilters—do not
recommend tuning the engines to specifications different from those of the engine
manufacturer.

Changes made to the design or operating conditions of the Purifilters, as exempted by the
ARB, which adversely affect the performance of the engine‘s pollution control system, shall
invalidate this Executive Order.

Purifilters may have on any warranty either expressed or implied by the engine
manufacturer.                    .

No claim of any kind, such as "Approved by the Air Resources Board," may be made with
respect to the action taken herein in any advertising or other oral or written communication.

In addition to the foregoing, the ARB reserves the right in the future to review this Execqutive

part continues to meet the standards and procedures of California Code of Regulations,
