HKS USA, INC.                                        EXECUTIVE ORDER D—186—15
HKS SPORT TURBO UPGRADE                              (Page 2 of 2)

This Executive Order is granted based on results from emissions tests
conducted in accordance with Cold—Start CVS—75 Federal Test Procedure.
However, the Air Resources Board finds that reasonable grounds exist to
believe that use of the HKS Sport Turbo Upgrade may adversely affect
emissions of motor vehicles when operating under conditions outside the
parameters of the previously prescribed test procedures.  Accordingly, the
Air Resources Board reserves the right to conduct additional emissions
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 HKS Sport Turbo Upgrade 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Order shall be effectively rescinded as of the date the test results are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 Air
Resources Board with reason to suspect that the HKS Sport Turbo Upgrade will
affect the durability of the emission control system,      HKS USA,    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
HKS Sport Turbo Upgrade 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 HKS Sport Turbo Upgrade 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 communication.

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 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 the
hearing that grounds for revocation exist.

Executed at El Monte, California, this     _/ S   day of June, 1994.

                                         Assistant Division Chief
