                                EXECUTIVE   ORDER D—437—1
                       Relating to Exemptions Under Section 27156
                                   of the Vehicle Code

                                 DKS TECHNOLOGIES, INC.
                              "DKS FUEL STABILIZER SYSTEM"

WHEREAS, Vehicle Code Sections 27156 and 38391, and Title 13, California Code of
Regulations (hereafter "CCR") Section 2222(e), authorize the California Air
Resources Board (ARB) and its Executive Officer to exempt add—on and modified
aftermarket devices from the prohibitions of Vehicle Code Section 27156.

WHEREAS, DKS Technologies, Inc. of 2226 Northpoint Parkway, Santa Rosa, California
95407, has applied to the ARB for exemption from the prohibitions in Vehicle Code
Sections 27156 and 38391 for their DKS Fuel Stabilizer System, Models E83700 and
ACV3700, for installation on 1997 and older model—year vehicles powered by a diesel
engine utilizing liquid coolant.  Model ES3700 uses electronic temperature control
valve,   and Model ACV3700 uses mechanical temperature control valve.

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 add—on device complies with the California Vehicle Code Section 27156 and
Title 13, California Code of Regulations.      It was determined through engineering
evaluation that the device will not reduce the effectiveness of the pollution
control system of applicable vehicles.

It has not been determined what effect use of the DKS Fuel Stabilizer System may
have on any warranty, either expressed or implied,     by the manufacturer or a motor
vehicle on which the device is installed.

IT IS HEREBY RESOLVED that the above DKS Fuel Stabilizer System 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 DKS Fuel Stabilizer System device as described
     in the application for exemption.      Any changes to the DKS PFuel Stabilizer
     System 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.

2.   Marketing of the DKS Fuel Stabilizer System using identifications other than
     those shown in this Executive Order or marketing of the DKS Fuel Stabilizer
     System for application other than the one listed 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 DKS Fuel Stabilizer System device as individual

3.   Any oral or written references to this Executive Order or its content by DKS
     Technologies, 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 emissions
     reduction claims for the DKS Fuel Stabilizer System and is only a finding that
     the DKS Fuel Stabilizer System is exempt from the prohibitions of Vehicle Code
     Section 27156.

4.   Should the installation of the DKS Fuel Stabilizer System on applicable
     vehicles be determined to result in unacceptable emission increase or cause
     adverse effect on pollution control systems of the vehicles, the ARB may
     require DKS Fuel Stabilizer System to conduct specific tests in order to   _
     determine the levels of emissions increase.  Should such tests show excessive
     emission increase, DKS Technologies, Inc. may be required to cease and @esist
     from marketing the device in California, and this exemption may be rescinded,
     in accordance with established procedures.

DKS TECHNOLOGIES, INC.                                          EXECUTIVE ORDER D—437—1

_further force and effect.
