IT IS ORDERED AND RESOLVED; That the installation of the CCX and CMX Diesel
Oxidation Catalytic Converters (CCX/CMX), manufactured and marketed by Englehard
Corporation, 101 Wood Ave., Iselin, NJ 08830—0770, has been found not to reduce the
effectiveness of the applicable vehicle pollution control system and, therefore, is exempt
from the prohibitions of Section 27156 of the Vehicle Code for installation on 2002 and
older model year on—road heavy—duty diesel engines not otherwise equipped with a
catalytic converter. The CCX is an integrated catalytic converter muffler while the CMX
is a catalyst only device.

This Executive Order is valid provided that the installation instructions for the CCX/ CMX
will not recommend tuning the vehicle to specifications different from those of the vehicle

This Executive Order shall not apply to any Englehard Corporation CCX/CMX
advertised, offered for sale, sold with, or installed on a motor vehicle prior to or
concurrent with the transfer to an ultimate purchaser.

This Executive Order shall apply only to CCX/CMX catalytic converters with a catalyst
formulation of A or B, as described in the Attachment. Changes made to the design or
operating conditions of the CCX/CMX, as exempt by the Air Resources Board, which
adversely affect the performance of the vehicle‘s pollution control system shall invalidate
this Executive Order.

Marketing of the CCX/CMX using any identification other than that shown in this
Executive Order or marketing of the CCX/CMX for an application other than those listed
in this Executive Order shall be prohibited unless prior approval is obtained from the Air
Resources Board. Exemption of the system shall not be construed as exemption to sell,
offer for sale, or advertise any component of the kit as an individual device.

This Executive Order does not constitute any opinion as to the effect that the use of the
CCX/CMX may have on any warranty either expressed or implied by the vehicle
manufacturer.                                         ‘

This Executive Order is granted based on test results submitted by Englehard
Corporation which demonstrated, using various heavy—duty diesel engines, that the
CCX/CMX has no adverse impact on exhaust emissions.

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 Title 13, California
Code of Regulations, Section 2222, et seq.


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 of other oral or written
communication.                                                                '

Violation of any of the above conditions shall be grounds for revocation of this order.

order, in which period the holder of the order may request in writing a hearing to contest

receipt of the request and the order may not be revoked until a determination is made,
after the hearing, that grounds for revocation exist.
