                                 EXECUTIVE ORDER D—249—5

                                 Relating to Exemptions under
                              Section 27156 of the Vehicle Code

                                   Donaldson Company, Inc.
                                            DPF Muffler

Pursuant to the authority vested in the Air Resources Board (ARB) by Section 27156 of the
Vehicle Code; and

Pursuant to the authority vested in theundersigned 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 DPF Muffler (Diesel Particulate
Filter Muffler DPM111144 and DPM111146), manufactured by Donaldson Company, Inc. of
1400 West 94‘" Street, Bloomington, Minnesota 55431, has been found not to reduce the
effectiveness of the applicable vehicle pollution control system, and therefore, the DPF
Muffler is exempt from the prohibitions in Section 27156 of the Vehicle Code for installation
on First Student, Inc.‘s school buses equipped with the following 4—stroke diesel engines, all
originally equipped with diesel oxidation catalysts:



                              Caterpillar              3126 (all horsepower)
              2004            Caterpillar                 C7 (all horsepower)

This Executive Order allows replacement of the original equipment manufacturer diesel
oxidation catalysts with Donaldson‘s DPF Mufflers. Donaldson will provide an original
equipment manufacturer—equivalent 5—year or 100,000—mile defects warranty on the DPF
Mufflers. The exemption under the Executive Order is limited to 280 school buses owned
by First Student, Inc. and operated in the Los Angeles Unified School District.

This Executive Order is only valid provided that the engines meet the following operating
conditions: (1) the engine exhaust temperature is greater than or equal to 225 degrees
Celsius for 40 to 50 percent of the duty cycle and (2) the engine is fueled with diesel having
a maximum sulfur content of 50 parts per million by weight.

This Executive Order is based on emission tests and engineering justification submitted by
Engelhard Corporation, supplier of the catalyzed filter used in the DPF Muffler. Test data
showed that the catalyzed filter does not adversely affect the exhaust emissions of the test
engines. The same emissions impact is expected when the DPF Muffier is installed on the
school buses equipped with any of the engines listed above.

This Executive Order is valid provided that installation instructions for the DPF Muffler do
not require tuning the vehicle to specifications different from those of the original engine or
vehicle manufacturer.                      —

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

POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF DONALDSON COMPANY,
