Pursuant to the authority vested in the Air Resources Board (ARB) by Section 27156 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 Continuously Regenerating
Technology (CRT) Particulate Filter, manufactured by Johnson Matthey of 380 Lapp Road,
Maivern, Pennsylvania 19355, has been found not to reduce the effectiveness of the
applicable vehicle pollution control system, and therefore, the CRT Particulate Filter is
exempt from the prohibitions in Section 27156 of the Vehicle Code for installation on
heavy—duty on—road vehicles equipped with the following 4—stroke diesel engines:



                                                  3208, 3116, 3126, 3306, 3406,

CRT Particulate Filters exempted under this Executive Order are identified in Attachment A.
This exemption is only valid provided the engines meet the following operating conditions:
(1) the engine exhaust temperature is greater than or equal to 260 degrees Celsius for 40 to
50 percent of the typical duty cycle, (2) the NOx to PM ratio is at least 8, and (3) the engine
is operated using diesel with a maximum sulfur content of 50 parts per million by weight.

This exemption is based on emission tests conducted by Johnson Matthey with the CRT
Particulate Filter. Testing showed that the CRT Particulate Filter does not adversely affect
the exhaust emissions of the test engines. The same emissions impact is expected when
the CRT Particulate Filter is installed on heavy—duty vehicles equipped with any of the
engines listed above.


                                               2.

This Executive Order is valid provided that installation instructions for the CRT Particulate
Filter do not recommend tuning the vehicle to specifications different from those of the
vehicle manufacturer.

Changes made to the design or operating conditions of the CRT Particulate Filter, as
exempt by the ARB, which adversely affect the performance of the vehicle‘s pollution
control system, shall invalidate this Executive Order.

Marketing of the CRT Particulate Filter using identification other than that shown in this
Executive Order or for an application other than that listed in this Executive Order shall be
prohibited unless prior approval is obtained from the ARB.

This Executive Order shall not apply to any CRT Particulate Filter advertised, offered for
sale, sold with, or installed on a motor vehicle prior to or concurrent with transfer to an
ultimate purchaser.

This Executive Order does not constitute any opinion as to the effect the use of the
CRT Particulate Filter may have on any warranty either expressed or implied by the vehicle
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 Executive
Order and the exemption provided herein to assure that the exempted add—on or modified
part continues to meet the standards and procedures of California Code of Regulations,
Title 13, Section 2222, et seq.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION,         .
ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE
AIR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING
ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF JOHNSON MATTHEY‘S
CRT PARTICULATE FILTER.

Viotation of any of the above conditions shall be grounds for revocation of this Executive
Order. The Executive Order may be revoked only after a ten—day written notice of intention
to revoke the Executive Order, in which period the holder of the Executive Order may
request in writing a hearing to contest the proposed revocation. If a hearing is requested, it
shall be held within ten days of receipt of the request, and the Executive Order may not be
revoked until a determination is made after a hearing that grounds for revocation exist.

Executed at El Monte, California, this     &”/      day of May 2003.
