                                       EXECUTIVE ORDER D—493
                              Relating to Exemptions Under Section 27156
                                           of the Vehicle Code

                                      DOWNING/ATLANTA, INC.
                                      BMW SUPERCHARGER KIT


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—45—9;

IT IS ORDERED AND RESOLVED: That the installation of the BMW Supercharger Kit, manufactured
and marketed by Downing/Atlanta, Inc., 5096 Peachtree Road, Atlanta, Georgia 30341 has been
found not to reduce the effectiveness of the applicable vehicle pollution control system and,
therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for 1999 and older
BMW vehicles equipped with a four cylinder fuel injected engine.

The BMW Supercharger Kit includes the following main components: Eaton M—62 supercharger,
intake manifold, fuel regulator, and an open element air cleaner. The stock air cleaner may also be
retained. No changes are made to the stock ignition system. The kit includes a 3.7" diameter
supercharger pulley and uses the stock crankshaft pulley. Maximum boost is limited to 7.5
psi.

This Executive Order is valid provided that the installation instructions for the BMW Supercharger Kit
will not recommend tuning the vehicle to specifications different from those of the vehicle
manufacturer.

This Executive Order shall not apply to any Downing/Atlanta, Inc. BMW Supercharger Kit advertised,
offered for sale, or sold with or installed on, a motor vehicle prior to or concurrent with transfer to an
ultimate purchaser.

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

Marketing of the BMW Supercharger Kit using any identification other than that shown in this
Executive Order or marketing of the BMW Supercharger Kit for an application other than those listed
in this Executive Order shall be prohibited unless prior approval is obtained from the Air Resources
Board.

Exemption of the BMW Supercharger Kit shall not be construed as exemption to sell, offer for sale, or
advertise any component of the kit as an individual device.

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


DOWNING/ATLANTA, INC.                                                   Executive Order D—493
BMW Supercharger Kit                                                    (Page 2 of 2)



This Executive Order is granted based on the following submitted emissions test data on a 1998
BMW Z3 equipped with a 1.9L engine and the BMW Supercharger Kit with the open element air
cleaner:

                  NMOG CO         NOx    HCHO
Standards         0.125 3.4       0.4    0.015
Device            0.094 1.3       0.3    0.001

Test results showed that tailpipe emissions with the Supercharger Kit installed on the vehicle met the
vehicle‘s applicable emission standard during Cold Start CVS—75 Federal Test Procedure. This               |
Executive Order is also based on On Board Diagnostic II (OBD II) testing conducted on the same
vehicle. Test data showed that the Supercharger Kit when installed on the vehicle did not affect the
vehicle‘s ability to perform its OBD II monitoring.

This Executive Order is granted based on submitted emissions test data which showed that the
Downing/Atlanta, Inc. Supercharger Kit did not adversely affect tailpipe emissions during the Cold
Start CVS—75 Federal Test Procedure. However, the ARB finds that reasonable grounds exist to
believe that use of the Supercharger Kit may adversely affect emissions of motor vehicles when
operating under conditions outside the parameters of the previously prescribed test procedures.
Accordingly, the ARB reserves the right to conduct additional emission tests in the future, as such
tests are developed, that will more adequately measure emissions from all cycle phases. If such test
results demonstrate that the supercharger adversely affects emissions during off—cycle conditions
(defined as those conditions which are beyond the parameters of the Cold—Start CVS—75 Federal
Test Procedure), this Executive Order shall be effectively rescinded as of the date the test results are
validated. Further, if such test results or other evidence provides the ARB with reason to suspect
that the supercharger will affect the durability of the emission control systems, Downing/Atlanta, Inc.
shall be required to submit durability data to show that the durability of the vehicle emission control
system is not, in fact, affected and/or that the add—on or modified part demonstrates adequate
durability.

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 of Title 13, California Code of Regulations, Section 2222, et seq.
THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION,
APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF
ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY
ALLEGED BENEFITS OF DOWNING/ATLANTA, INC.‘S BMW SUPERCHARGER 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 order. The order may
be revoked only after a ten—day written notice of intention to revoke the order, in 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 after hearing that grounds for revocation exist.
