                               EXECUTIVE ORDER D—547U—1

                               Relating to Exemptions under
                       Sections 38390 and 38391 of the Vehicle Code

                                    Haldor Topsge A/S
                         Urea Selective Catalytic Reduction System

  Pursuant to the authority vested in the Air Resources Board (ARB) by Part 5, Division
  26 of the Health and Safety Code and Sections 38390, 38391, and 38395 of the Vehicle
  Code; and

  Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the
  Health and Safety Code and Executive Order G—02—003;

  IT |S ORDERED AND RESOLVED: That installation of the Urea Selective Catalytic
_ Reduction (SCR) System, manufactured by Haldor Topsge AVS of Nymallevej 55,
  DK—2800, Lyngby, Denmark, has been found not to reduce the effectiveness of the
  applicable engine emission control system, and therefore, the Urea SCR System is
  exempt from the prohibitions in Sections 38390 and 38391 of the Vehicle Code for
  installation on 1996—2002 model—year 4—stroke diesel and diesel/natural gas bi—fuel
  engines (< 600 hp) used in off—road equipment.

 The Urea SCR System consists of a urea injection system, an SCR catalyst, and control
 sensors. The injection system includes a combined dosing pump and electronic control
 unit, valve manifold, urea/air atomizer, and a urea storage tank. The sensors include a
 NOx sensor, mass air flow sensor, and two temperature sensors. The system
 components exempted under this Executive Order are identified in Attachment A.

 This exemption is based on emission tests conducted by Haldor Topsa@e A/S with the
 Urea SCR System. Test data showed that the Urea SCR System has no adverse
 impact on engine emissions.

 This Executive Order is valid provided that installation instructions for the Urea SCR
 System do not recommend tuning the engines to specifications different from those of
 the engine manufacturer.

 Changes made to the design or operating conditions of the Urea SCR System, as
 exempted bythe ARB, which adversely affect the performance of the engine‘s pollution
 control system, shall invalidate this Executive Order.

 Marketing of the Urea SCR System using identification other than that shown in this
 Executive Order or for an application other than that listed in this Executive Order shall
 be prohibited unless prior approval is obtained from the ARB.


                                               «2.

This Executive Order shall not apply to any Urea SCR System advertised, offered for
sale, sold with, or installed on an off—road engine or equipment prior to or concurrent
with transfer to an ultimate purchaser.

This Executive Order does not constitute any opinion as to the effect the use of the
Urea SCR System may have on any warranty either expressed or implied by the engine
manufacturer.

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.

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 2474, 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 HALDOR TOPSOE
AS® UREA SELECTIVE CATALYTIC REDUCTION SYSTEM.

Viotation of any of the above conditions shall be grounds for revocation of this Executive
Ordér. The Executive Order may be revoked only after a ten—day written notice of
intention to revoke the Executive Order, in which period the holder of the Executive
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 Executive
Order may not be revoked until a determination is made after a hearing that grounds‘for
revocation exist.

Executed at El Monte, California, this Z_Z_"D        day of October 2002.
