                                   EXECUTIVE ORDER D—353
                         Relating to Exemptions Under Section 27156
                                    of the Vehicle Code

                                MILLER CATALYZER CORPORATION

     WHEREAS, Vehicle Code Section      27156 and Title 13 California Code of
     Regulations (hereafter "CCR")      Section 2222(i), authorize the California Air
     Resources Board (ARB) and its      Executive Officer to exempt used aftermarket
     catalytic converters from the      prohibitions in Vehicle Code Sections 27156
     and 38391.

     WHEREAS, Miller Catalyzer Corporation of 3295 Depot Road, Hayward,
     California 94545, has applied to the ARB for exemption from the prohibitions
     in Vehicle Code Sections 27156 and 38391 to market used original
     manufacturer (OEM} two—way or oxidation converters (OC), three—way
     converters (TWC), three—way plus oxidation converters (TWC + OC), and
     precatalysts in California.  Miller Catalyzer Corporation shall salvage,
     recondition (as necessary), and test the converters for application on
     vehicles identical to the certification vehicles.

    WHEREAS, pursuant to the authority vested in the Executive Officer by Health
    and Safety Code Section 39515 and in the Chief, Mobile Source Division by

    Health and Safety Code Section 39516 and Executive Order G—45—5,          the ARB
    —finds that the Miller Catalyzer Corporation used catalytic converters comply
    with the California Vehicle Code Sections 27156 and 38391,          and Title 13,
    California Code of Regulations, Section 2222(i).

    IT IS HEREBY RESOLVED that Miller Catalyzer Corporation used catalytic
    converters are exempt from the prohibitions in Vehicle Code Sections 27156
    and 38391 for installation on applicable vehicles subject to the following

       1.   Used catalytic converters marketed in California must attain the
            minimum conversion efficiencies shown below within the specified time
            after the exhaust is switched to pass through the catalytic

                              Minimum Conversion Efficiency
            Converter Type       _HC_     co    NOx              Time
            oc                   70%     70%    =               60 sec
            TWC                  70%     70%    60%             60 sec
            TWC + OC             70%     70%    50%             60 sec
            Precatalysts         40%     40%    —               60 sec

       2.   No changes are permitted to the catalytic converters as described in
            the application for exemption.  Any changes to the catalytic
            converters or any of their components, applicable model year, or
            other factors addressed in this order must be evaluated and approved
            by the ARB prior to marketing in California.

       3.   Marketing of the converters using identifications other than those
            shown in the exemption application or marketing of the catalytic
            converters for vehicle applications other than those identical to the
            certification vehicles shall be prohibited unless prior approval is
            obtained from the ARB.  Exemption of these products shall not be

    MILLER CATALYZER CORP                                 EXECUTIVE ORDER D—353

             construed as an exemption to sell,    offer for sale,   or advertise any
             components of the catalytic converters as individual devices.

       4.    Any oral or written references to this Executive Order or its content
        °_   by Miller Catalyzer Corporation, 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 emissions reduction claims for
             the catalytic converters and is only a finding that the catalytic
             converters are exempt from the prohibitions of Vehicle Code Sections
             27156 and 38391.

       5.    Miller Catalyzer Corporation must submit their quality audit data or
             quality control procedures, as well as production quantity data for
             each converter type produced, to the ARB for review on a semi—annual
             basis no later than August 15 and February 15 for each production
             year.  For the first calendar year following the exemption of their
             used catalytic converters, the production audit testing shall
             demonstrate correlation between conversion efficiencies of two TWC
             and two TWC + OC determined using the procedures established by
             Miller Catalyzer Corporation and the cold—start CVS—75 Federal Test
             Procedure. The test parameters shall be specified by the ARB and will
             be sent to Miller Catalyzer Corporation not less than 30 days before
             the end of the reporting period.  Failure to establish correlation
             between the conversion efficiency obtained using the CVS—75 and the

             conversion efficiency obtained using the procedures developed by
             Miller Catalyzer Corporation may cause the ARB to require Miller
             Catalyzer Corporation to review and modify its procedures.

       6.    Miller will be required to adopt a new bench test procedures should
             the ARB develop a bench test procedures for screening OEM catalytic
             converters which are more stringent than those used by Miller, in the

    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     2     day of February,    1994.
