_ for the: hydrogen gasand oxygen gas.                                  .

  This Executive Order is based on emission test results using Heavy-Duty Federai Test
 . Procedure (FTP) Transient Cycle test submitted by HH2 Energy Inc. with the HH2
   Hydrogen Generator Device.

  HH2 Energy Inc. shall be required to submit durability 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 parts demonstrate adequate durability,                           —

_ This Executive Order is valid provided that installation mstructlons for the HH2
  Hydrogen Generator Device do not recommend tuning the vehicles to spemflcahons
  different from those of the vehicle manufacturer.

  Changes made to the design or operating conditiohs of the‘ HH2 Hydrogen Generator
  Device, as exempt by the Air Resources Board, which adversely affect the performance
  of the vehicle‘s emission control system, shall invalidaté this Executive Order.

  Marketing of the HH2 Hydrogen Generator Device using identification other thanthat
  shown in this Executive Order or for an application other than that listed in this
. Executive Order shall be prohibited unless prior approval is obtamed from the Air
  Resources Board.

    Exemption of the HKH2 Hydrogen Generator Device shall not be construed as exemption
    to sell, offer for sale, or advertise any component of the kit as an individual device.

    This Executive Order shall not apply to any HH2 Hydrogen Generator Device
    advertised, offeredfor sale, sold with, or installed on a motor vehicle prlor to or

  Manufacturer Name: HH2 Energy Inc.

_ Name of Device: HH2 Hydrogen Generator Device

         HH2 Energy Inc. of 23100 Valerio St., West Hills, CA 91307 has applied for exemptlon
  from the prohibitions in Section 27156 of the Cahforn;a Vehicle Code for its HH2 Hydrogen .
  Generator Device. The device is designed for all 1900—2000 model year (MY)
  light/medium/heavy heavy—duty on—road gasoline or diesel engines up to 20.0 liters.

         Grant exemptionto HKH2 Energy Inc. asrequested andissue Executlve Order

  Device Description:
            The HH2 device produces hydrogen through an electrolySIS process by supplying
   electricity from the vehicle‘s battery to stainless steel metal tubes submerged in a reservoir
   containing distilled water and an electrolyte (sodium citrate). The device is connected to the
 _ vehicle‘s battery through a relay switch so that hydrogen gas is only produced when the engine
   is operating. The device consists of an acrylic water reservoir (which contains the metal tubes),
   relay switches, electrical wiring and connectors, an electrolyte (sodlum citrate), and vinyl supply
   hoses for the hydrogen gas and oxygen gas.                                               .

  DlscuSSIon/BaS|s for the Recommendatlon
         This exemption is based. on the following emission test conducted on a 2000 MY
  Cummins ISM 10.8L heavy—duty diesel engine, engine family YCEXHOS61MAI, with HH2
  Energy Inc.‘s HH2 Hydrogen Generator Device installed:

  The emission test results are shown below:

 . All exhaust emission test results for FTP transient cycle emission testing on the 2000 MY
  Cummins ISM 10.8L heavy—duty diesel engine modified with the HH2 Hydrogen Generator
  Device showed that the modified engine met the exhaust emission standards. Similar results
  are expected when HH2 Energy Inc.‘s HKH2 Hydrogen Generator Device is used on the
  1900—2000 MY light/medium/heavy heavyduty on—road gasoline or diesel engines up to 20.0
. liters as stated in this application:
