 LINGENFELTER 383 CID LT—1 ENGINE                 (Page 2 of 2)

 This Executive Order is granted based on the results from previous emission
 tests conducted in accordance with Cold—Start CVS—75 Federal Test Procedure.
 However, the ARB finds that reasonable grounds exist to believe that use of
 the Lingenfelter 383 CID LT—1 Engine may adversely affect emissions of motor
 vehicles when operating under conditions outside the parameters of the
 previously prescribed test procedure. Accordingly, the ARB reserves the
 right to conduct additional emission tests in the future, as such tests are
dgveloped, that will more adequately measure emissions from all cycle
phases.                                                       .

If such test results demonstrate that the Lingenfelter 383 CID LT—1 Engine
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Test Procedure), this Executive Order shall be effectively rescinded as of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 reasons to suspect that the
Lingenfelter 383 CID LT—1 Engine will affect the durability of the emission
control system, Lingenfelter shall be required to submit durability test
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 California Code of Regulations, Title 13, 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
CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED
BENEFITS OF LINGENFELTER PERFORMANCE ENGINEERING, INC.‘S LINGENFELTER 383
CID LT—1 ENGINE.

 made with respect to the action takem herein in any advertising or other

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
