This Executive Order does not constitute any opinion as to the effect the use of the High—Lift Camshaft
Set may have on any warranty either expressed or implied by the vehicle manufacturer.

This Executive Order is granted based on the following submitted emissions test data on a 1997 Acura
NSX certified to a tier 1 emission standard:
                     NMHC       CO      NOX
Standards            0.25       3.4     0.4
device w/ dfs        0.19       1.2     0.2

Test results showed that tailpipe emissions with the High—Lift Camshaft Set 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 1997
Acura NSX. Test data showed that the High—Lift Camshaft Set when installed on the vehicle did not
affect the vehicle‘s ability to perform its OBD II monitoring.

APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF
ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY    *

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.

Executed at El Monte, California, this 3 51 day of June 1998.
