                              EXECUTIVE ORDER D-621

                             Relating to Exemptions under
                           Section 27156 of the Vehicle Code

                              Oil Purification Systems, Inc.
                                          OPS-1

Pursuant to the authority vested in the Air Resources Board by Section 27156 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 IS ORDERED AND RESOLVED: That installation of the OPS-1, manufactured by Oil
Purification Systems, Inc. of 2176 Thomaston Avenue, Waterbury, Connecticut 06704,
has been found not to reduce the effectiveness of the applicable vehicle pollution
control systems, and therefore, are exempt from the prohibitions in Section 27156 of the
Vehicle Code for installation on 2007 model-year and older heavy-duty diesel engines
with pressurized oil systems.

The OPS-1 device is a two-stage oil refining system consisting of a Filtration chamber
and an evaporation chamber. It is set-up as a closed-loop system with the evaporative
emissions from the evaporation chamber vented back into the air intake system.

This Executive Order is based on engineering evaluation which determined that the
device when installed on 2007 and older heavy-duty diesel engines with pressurized oil
syste'ms will not adversely affect the performance of emission control systems of
affected engines.

This Executive Order is valid provided that installation instructions for the OPS-1 do not
recommend tuning the vehicles to specifications different from those of the vehicle
manufacturer.

Changes made to the design or operating conditions of the OPS-1, as exempt by the Air
Resources Board, which adversely affect the performance of ,the vehicles' emission
control system, shall invalidate this Executive Order.

Marketing of the OPS-1 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 Air Resources Board.

Exemption of the OPS-1 shall not be construed as exemption to sell, offer for sale, or
advertise any component of the systems as an individual device.


This Executive Order shall not apply to any OPS-1 advertised, offered for sale,
sold with, or installed on a niotor vehicle 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 OPS-I may have on any warranty either expressed or implied by the vehicle
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 Air Resources Board 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 ANY CLAIMS OF THE APPLICANT
CONCERNING ANTI-POLLUTION BENEFITS OR ANY ALLEGED BENEFITS
OF OIL PURIFICATION SYSTEMS, INC.'S OPS-1.

Violation of any of the above conditions shall be grounds for revocation of this
Executive Order. 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 the hearing that grounds for revocation exist.

Executed at El Monte, California, this     26 day of June 2007.

                                         Annette Hebert, Chief
