                       Relating to Exemptions Under Section 27156
                                  of the California Vehicle Code

                                       Tii Trading Co.
                                  Tiico Engine Conversion

Pursuant to the authority vested in the Air Resources Board by Section 27156 of the
Vehicle Code; and

Pursuant to the authority vested in the undersigned by Section 39515 and Section
39516 of the Health and Safety Code and Executive Order G—02—003;

IT IS ORDERED AND RESOLVED: That the installation of the Tiico Engine Conversion,
produced and marketed by Tii Trading Co., 3031 Alhambra Dr., Suite 202, Cameron Air
Center, Cameron Park, California 95682, has been found not to reduce the
effectiveness of the applicable vehicle pollution control systems and, therefore, is
exempt from the prohibitions of Section 27156 of the Vehicle Code for the 1983 through
1991 model—year VW Vanagon.

The Tiico Engine Conversion includes the following main components: a South African
rebuilt 1991 Audi 80/90 2.0 Liter 4 cylinder engine with a 1993—1996 Golf/Jetta intake
manifold (to allow room for installation in the Vanagon engine compartment, p/n 037
133 201AP). The throttle body of the engine has been fitted with an inlet for connection
to the evaporative system. The ECU utilized is the stock 1991 Audi 80/90 unit, p/n 893
907 404. The original vanagon catalytic converter is retained. Also included are
brackets and hardware necessary for installation of the engine.

This Executive Order is valid provided that the installation instructions for the Tiico
Engine Conversion will not recommend tuning the vehicle to specifications different from
those of the vehicle manufacturer for the 1991 Audi 80/90 engine utilized in the Tiico
Engine Conversion.

Changes made to the design or operating conditions of the Tiico Engine Conversion, as
exempt by the Air Resources Board, which adversely affect the performance of the
vehicle‘s pollution control system shall invalidate this Executive Order.

This Executive Order shall not apply to any Tiico Engine Conversion advertised, offered
for sale, sold with, or installed on a new motor vehicle prior to or concurrent with transfer
to an ultimate purchaser.

Marketing of the Tiico Engine Conversion using any identification other than that shown
in this Executive Order or marketing of the Tiico Engine Conversion for an application

«—   other than those listed in this Executive Order shall be prohibited unless prior approval
     is obtained from the Air Resources Board.

     This Executive Order does not constitute any opinion as to the effect the use of the Tiico
     Engine Conversion may have on any warranty either expressed or implied by the
     vehicle manufacturer.

     This Executive Order is granted based on an examination of a 1987 VW Vanagon in the
     modified configuration using the Cold—Start CVS—75 Federal Test Procedure. Test data
     showed that the Tiico Engine Conversion will have no adverse impact on the vehicle‘s
     emissions. Results from emissions testing conducted at Northern California Diagnostic
     Labs are shown below (in grams per mile):

                            50k           HC       CO         NOx
                      Emission Level     0.154     0.998      0.685
                      (w. DF applied)
                            STD          0.50      9.0        1.0

     If evidence provides the ARB with reason to suspect that the Tiico Engine Conversion
     will affect the durability of emission control systems, Tii Trading Co. shall be required to
     submit durability data to show that the durability of vehicle emission control systems are
     not, in fact, affected and/or that the add—on or modified part demonstrates adequate

     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 or other oral or written

                        TIl TRADING CO. — TIICO ENGINE CONVERSION — D—573

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

Executed at El Monte, California, this    _ _/ ST.    day of October 2003.
