   The WhippleCharger is a supercharger consisting of the following main components: Twin
   Screw Whipple supercharger, two auxiliary fuel injectors (one injector on the PT—Cruiser) with
   a stand alone computer, air bypass valve, a low temperature thermostat to replace stock
   thermostat, and a newair cleaner element for use in the stock air cleaner housing.
~ _ Intercooler is included on selected kits and denoted as IC in the part number. The maximum
   boost is 8 psi. on the Ford and General Motors vehicles and 9.2 psi. on the Chrysler
   PT—Cruisers.

   This Executive Order is valid provided that the installation instructions for the supercharger
   will not recommend tuning the vehicle to specifications different from those of the vehicle °
   manufacturer. Whipple Industries, Inc. recommends that only premium fuel be used.

   Changes made to the design or operating conditions of the WhippleCharger, 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 Whipple Industries WhippleCharger advertised,
   offered for sale, sold with, or installed on a motor vehicle prior to or concurrent with transfer
   to an ultimate purchaser.

   Marketing of the supercharger using any identification other than that shown in this Executive
   Order or marketing of the supercharger 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 supercharger 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
   supercharger may have on any warranty either expressed or implied by the vehicle
   manufacturer.

   This Executive Order is granted based on emissions test data generated on the following test
   vehicles using the Cold Start CVS—75 Federal Test Procedures. Emission levels of the
   modified vehicles met the applicable emission standards. The following test results are in
   grams per mile:

This Executive Order is also based on On—Board Diagnostic I! (OBD [I) tests conducted on
the same test vehicles. Test data showed that the supercharger when installed on the
vehicles 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 show that
emissions are not affected during the Cold—Start CVS—75 Federal Test Procedures. However,
the ARB finds that reasonable grounds exist to believe that use of the WhippleCharger 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 WhippleCharger adversely affects emissions during off—cycle conditions (defined as
those conditions which are beyond the parameters of the Cold—Start CVS—75 Federal Test
Procedures), 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 WhippleCharger will affect the durability of the emission control system, Whipple 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.
