         including, without limitation, U.S. Department of State, Treasury or
         Commerce Export Control or other U.S. Government.

         Non-performance in whole or in part by either party because of said
         applicable laws shall not constitute a default or breach by such party
         of its obligations hereunder, or subject such party to liability to the
         other party for damage or convey any right to the other Party to
         terminate this Agreement.

         MIC covenants that it is familiar with the U.S. Foreign Corrupt
         Practices Act of 1977, as amended, "the Act", and it proposes and
         represents that neither MIC nor any of its shareholders, officers,
         directors, or employees will perform any service or action related to
         this Agreement that would or might constitute any such violation.

14.      AMENDMENTS

         This Agreement may be amended only by written agreement of both MIC and
         WXT.

15.      ASSIGNMENT

         This Agreement is assignable by WXT to EnerTeck upon giving reasonable
         written notice to MIC and subject to EnerTeck agreeing to appropriate
         changes to reflect that the Agreement would be between EnerTeck and the
         distributor. Otherwise, neither party shall have the right to assign
         all or any part of its rights, duties or obligations hereunder without
         the prior written consent of the other party, which shall not be
         unreasonably withheld.

         This Agreement is binding and enforceable against the parties and their
         respective successors, and permitted assigns.

16.      GEOGRAPHIC EXCLUSIVITY

         In consideration of MIC's efforts in newly developing the business of
         marketing the Products in the Territory, MIC shall have exclusive sales
         and distribution rights throughout the Territory for an initial period
         of one year from the effective date of this agreement. WXT agrees to
         provide to MIC marketing and technical support commensurate with that
         provided to WXT's other International distributors of EnerBurn
         products. After such initial exclusivity period, MIC shall retain the
         right of geographic exclusivity for all countries listed in Exhibit "A"
         as long as MIC is providing a satisfactory service to WXT. If the
         minimal annual purchase volumes outlined in Exhibit "B" are not met in
         any given year, WXT, by its sole decision may terminate the extended
         geographic exclusivity for MIC.

         During the period of exclusivity for the Territory, WXT shall not sell
         Products either directly or indirectly to any entity in the Territory
         and shall refer to MIC any inquiries it may receive from any such
         entity.

         In the event geographic exclusivity is terminated for less than minimum
         sales as provided for in Appendix "B" of this Agreement, MIC shall have
         extended exclusivity for any customer who has

                                  Page 5 of 13                                 5

         Products in commercial quantities prior to the end of the Geographic
         exclusivity period as long as this Agreement is in force.

17.      TERM AND TERMINATION

         (a)      This Agreement shall be effective as of the Effective Date and
                  shall continue in force for an initial term of five (5) years
                  and thereafter and shall be automatically renewed for
                  successive one-year terms unless terminated by either party by

                  party.

         (b)      Notwithstanding the foregoing, this Agreement may be
                  terminated by either party with immediate effect and without
                  recourse against the terminating party upon the occurrence of
                  any of the following events:

                  (i)      The other party breaches any material obligation
                           imposed by this Agreement providing that such
                           material breaches are not reasonably remedied within
                           sixty (60) days of written notice of breach.

                  (ii)     The other party fails to make any payment of sums
                           owed by it hereunder when due.

                  (iii)    The other party becomes insolvent, or subject to a
                           petition in bankruptcy filed by or against it or is
                           placed under the control of receiver, liquidator or
                           committee of creditors.

                  (iv)     The other party assigns transfers or attempts to
                           assign or transfer this Agreement without the
                           terminating party's prior consent.

         (c)      Notwithstanding the foregoing, the Agreement may be terminated
                  by WXT with immediate effect upon the occurrence of any of the
                  following events:

                  (i)      A period of one hundred eighty days (180 days) from
                           the Effective Date of this agreement passes without
                           WXT receiving a valid and acceptable purchase order
                           of commercial quantities for the Products in the
                           Territory.

         (d)      Notwithstanding any termination of this agreement, WXT agrees
                  to honor any orders for products placed by MIC prior to the
                  effective date of termination.

              PRICE SCHEDULE, MINIMUM PURCHASES AND MARGIN SHARING

The Base Price of EnerBurn 5805C (or equivalent) to MIC shall be USD 66.00
(sixty-six dollars) per US Gallon in bulk. Other packaging such as drums or
pails will be price-adjusted as necessary to reflect additional packaging and
handling costs to WXT.

WXT can amend the base price with sixty days (60) notice to MIC to reflect
changes in WXT's product acquisition cost. Product is offered FOB the Port of
Houston, Texas, USA.

The base price will be adjusted for volume incentive for any particular country
of destination/sale as follows:

Up to 6500 US Gallons per any given calendar quarter. - No Adjustment.

6500 US Gallons to 12,999 US Gallons per any given calendar quarter. - USD 2.00
Discount.

13,000 US Gallons to 19,999 US Gallons per any given calendar quarter. - USD
4.00 Discount

20,000 plus US Gallons any given calendar quarter - USD 6.00 Discount.

Example: Sales to Japan in 1st quarter 2003 are 13,200 US Gal. (two isotanks).
Base price would be adjusted by USD 4.00. At a Base Price of USD 66.00, the net
FOB price is USD 62.00 per gallon.

Excess Margin share for MIC = (105.00 - 90.01)*0.60 = USD 8.994 Excess Margin
