                             Relating to Exemptions Under Section 27156
                                          of the Vehicle Code

                               JOHNSON MATTHEY, INC.
                       CAM CONVERTER TECHNOLOGY UPGRADE KIT


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—45—9;

IT IS ORDERED AND RESOLVED: That installation of the Cam Converter Technology (CCT)
Upgrade Kit, manufactured by Johnson Matthey, Inc. of 460 East Swedesford Road, Wayne,
Pennsylvania 19087—1880, has been found not to reduce the effectiveness of the applicable vehicle
pollution control system, and therefore, the CCT Upgrade Kit is exempt from the prohibitions of
Section 27156 of the Vehicle Code for installation on 1985—1993 model—year Detroit Diesel
Corporation (DDC) 6V92ZTA DDEC two—stroke urban bus diesel engines with power ratings of 253
and 277 horsepower.

The CCT Upgrade Kit rebuilds all applicable engines to federal 1991—1993 model—year DDC
specification. The CCT Upgrade Kit is exempt only when used in conjunction with other DDC engine
rebuild parts. The required CCT Upgrade Kit parts and DDC rebuild parts are listed in the parts lists
which are attached hereto and incorporated herein.

The CCT Upgrade Kit includes patented engine camshafts, CCT cylinder kits, CEM II catalytic
mutffler, and 0.015 offset key to retard fuel injection timing. For 1985—1987 model—year engines, the
CCT Upgrade Kit also includes DDEC I to DDEC II conversions parts, fuel injectors, turbocharger,
blower assembly, blower bypass valve, 40—tooth blower drive gear, and an ECM upgrade. For
1988—1990 model—year engines, the CCT Upgrade Kit also includes fuel injectors and an ECM
upgrade.

For 1985—1990 model—year engines, DDC‘s revised certification word codes listed in Attachment A
must be used. For 1991—1993 model—year engines, the revised certification word codes may be used.

This exemption is based on emission tests conducted by Johnson Matthey, Inc. on a 1992 model—year
6GV9ZTA DDEC II engine rebuilt to a federal 1991 model—year urban bus engine configuration.
Johnson Matthey, Inc. submitted the following federal transient heavy—duty diesel engine test results
for a 552 cubic inch G6V92TA DDEC engine with a 277 horsepower rating:

       Emission Standard          1.3     15.5    5.0     0. 1



The test data show that the CCT Upgrade Kit did not adversely affect the exhaust emissions of the
DDEC GV9ZTA engine. The same emissions impact is expected when the CCT Upgrade Kit is
installed on the engines for which the exemption is requested.

This Executive Order is valid provided that installation instructions for the CCT Upgrade Kit not
recommend tuning the vehicle to specifications different from those submitted by the vehicle
manufacturer.

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

Marketing of the CCT Upgrade Kit using an identification other than that shown in this Executive
Order or for an application other than those listed in the attachments shall be prohibited unless prior
approval is obtained from the ARB.

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

This Executive Order does not constitute any opinion as to the effect the use ofthe CCT Upgrade Kit
may have on any warranty either expressed or implied by the vehicle manufacturer.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION,
APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD
OF CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY
ALLEGED BENEFITS OF JOHNSON MATTHEY, INC.°S CCT UPGRADE KIT.

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.

Violation 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
ofthe request and the Executive Order may not be revoked until a determination after the hearing that
grounds for revocation exist.
