                                       EXECUTIVE ORDER D—280—4
                           Relating to Exemptions Under Section 27156
                                       of the Vehicle Code

                                 AIRTEK, INC. (dba CATCO)
WHEREAS, Vehicle Code Sections 27156 and 38391, and Title 13, California  Code
of Regulations (hereafter "CCR") Section 2222(h), authorize the  California
Air Resources Board (ARB) and its Executive Officer to exempt new aftermarket
catalytic converter from the prohibitions of Vehicle Code Section 27156.

WHEREAS, AirTek, Inc. (AirTek) of 4410 w. 37° Ave, Hobart, Indiana 46342, has
applied to the ARB for exemption from the prohibitions in Vehicle Code
Sections 27156 and 38391 to market their aftermarket series 4444000 three—way
plus oxidation catalytic converter (TWC + OC) for the following application,
except for vehicles equipped with an on—board diagnostic II system:

Type            Use          Series No.     Max.   Eng.   Size    Max.   Test Veh.   Wt.
TWe + oc        oC           4444000        5.9L (360 CID)        5,500 lbs.
TWC + oC        TWC          4444000        5.9L   (360 CID)      5,500 lbs.
TWC + Oc        TWC + OC     4444000        5.9L   (360 CID)      5,500 lbs.

WHEREAS, pursuant to the authority vested in the Executive Officer by Health
and Safety Code Section 39515 and in the Chief, Mobile Source Operations
Division by Health and Safety Code Section 39516 and Executive Order G—45—9,
the ARB finds that the above aftermarket catalytic converter complies with the
California Vehicle Code Section 27156 and Title 13, California Code of
Regulations,          Section 2222(h).    Emission performance of the catalytic converter
was based on durability mileage accumulation on the catalyst for 25,000 miles
using a 1976 and a 1978 5.9L Chrysler Cordoba vehicles and AMA driving cycle
(Reference Appendix IV, Title 40, part 86, Code of Federal Regulations (June
28, 1977)).

Whereas, emissions tests conducted at California Environmental Engineering
(CEE),    Santa Ana,       California,    showed the following conversion efficiencies
which meet the minimum requirements for new aftermarket catalytic converters:

                                            Catalyst Application Type
Pollution Component                        THC + 0C            TWC        ac

IT IS HEREBY RESOLVED that the above catalytic converter is exempt from the
prohibitions in Vehicle Code Section 27156 for installation on the approved
application vehicles subject to the following conditions:

         1..     No changes are permitted to the catalytic converter as described
                 in the application for exemption.  Any changes to the catalytic
                 converter or any of its components, and other factors addressed in
                 this order must be evaluated and approved by the ARB prior to
                 marketing in California.

AIRTEK, INC. (dba CATCO)                               EXECUTIVE ORDER D—280—4
"TWC + OC SERIES 4444000"                              (Page 2 of 2)

      2.    Marketing of the catalytic converter using identifications other
            than those shown in the exemption application, and in this
            Executive Order, or marketing of the catalytic converter for
            application other than the ones shown in this Executive Order
            shall be prohibited unless prior approval is obtained from the
            ARB.   Exemption of this product shall not be construed as an
            exemption to sell,   offer for sale,    or advertise any components of
            the catalytic converter as individual devices.

      3.    Any oral or written references to this Executive Order or its
            content by AirTek, Inc., its principals, agents, employees,
            distributors,   dealers,    or other representatives must include the
            disclaimer that the Executive Order or the exemption it provides
            is not an endorsement or approval of any emission reduction clains
            for the catalytic converter and is only a finding that the
            catalytic converter is exempt from the prohibitions of Vehicle
            Code Section 27156.

      4.    AirTek, Inc.    installation instructions for the new catalytic
            converter must conform to requirements      in Paragraphs I and IX of
            California Evaluation Procedures for New Aftermarket Non—Original
            Equipment Catalytic Converters.

      5.    Upon installation, the catalytic converter must carry a
            manufacturer‘s warranty for 25,000 miles on the substrates and
            50,000 miles or five years on the shell and end pipes.

Violation of any of the above conditions shall be grounds for revocation of
this order.  The order may be revoked only after ten day written notice of
intention to revoke it, during which period the holder of the 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 order may not be revoked until a determination is made, after the hearing,
that grounds for revocation exist.

Executed at El Monte,   California,    this
