                                  set by the Distributor, or MTI and the

                                  "Annual Goal Default"), then MTI may
                                  terminate this Agreement in accordance with

         d.      Normal Retail Price.  Concurrent with each submission of
                 Annual Goal by the Distributor under this Agreement, the
                 Distributor shall also submit to MTI the "Normal Retail Price"

                 are sold to the end user of the Products, normally a repair
                 garage or   service center.  Notwithstanding the foregoing,

                 Territory any other products that are similar to, or
                 competitive with, the Products.  For the same period,
                 Distributor will not attempt to replicate, sell, promote,
                 distribute or manufacture any cleaning solution or fuel system
                 cleaning machines for use, under any circumstances, with or
                 without MTI's patented and proprietary technology or systems.
                 Any such actions by Distributor would substantially and
                 permanently damage MTI, and result in the immediate
                 termination of this Agreement (if applicable).  In connection
                 with the above, MTI will be entitled to seek any remedy
                 available at law or in equity.

         f.      Restrictions With Respect to Proprietary Information.

                 (i)      Trade Secrets.  Distributor hereby acknowledges and
                          agrees that MTI owns certain trade secrets and other
                          confidential and/or proprietary information and
                          intellectual property which constitute valuable
                          property rights, which MTI has developed through a
                          substantial expenditure of time and money, which are
                          and will continue to be utilized in MTI's business
                          and which are not generally known to the trade. This
                          proprietary information expressly includes, but is
                          not limited to, the list of names of the
                          distributors, dealers, customers and suppliers of
                          MTI, the identities of key personnel of the
                          distributors, dealers, customers and suppliers of
                          MTI, and other information concerning the Products,
                          finances, personnel contractors processes,  pricing
                          information, production schedules and other types of
                          proprietary information relating to MTI's operations.
                          In recognition of these facts, Distributor hereby
                          agrees that the Distributor, both during and after
                          the term of this Agreement:

                          (a)     Will not use or disclose, directly or
                                  indirectly, and will keep secret and
                                  confidential, all trade secrets and
                                  proprietary

                          (c)     Upon the termination of this Agreement or at
                                  anytime  at MTI's request, Distributor shall
                                  return all documents or materials which have
                                  been furnished to Distributor by MTI in
                                  connection with this Agreement; and

                          (d)     All uses by Distributor of MTI's name or any
                                  trademarks or tradenames (or any other marks
                                  or names closely resembling the same) now and
                                  hereafter owned by MTI or its affiliates
                                  shall be subject to prior written approval by
                                  MTI. Distributor is not authorized to use
                                  MTI's names or trademarks in connection with
                                  any aspect of its business other than in the
                                  sales, marketing and advertising of the
                                  Products.

         g.      Distributor Further Acknowledges and Agrees :

                 (i)      Copying, duplicating, or imitating the Products by
                          Distributor is illegal and would result in permanent
                          irreparable injury to MTI.  Any such activities will
                          cause an immediate termination of this Agreement, and
                          MTI will be entitled to seek any remedy available at
                          law or in equity.

                 (ii)     Distributor may sell the Products only in the
                          Territory.  If Distributor sells any Products outside
                          said Territory, either directly or indirectly, the
                          Distributor shall be in breach of this Agreement and
                          MTI shall have the right to terminate this Agreement
                          at its sole discretion by providing the Distributor
                          with 90 days advance written notice. MTI shall not be
                          required to sell to the Distributor any further
                          Products after notification of termination has been
                          sent by MTI to the Distributor.

         h.      Purchase Price.  MTI will sell to the Distributor the Products
                 at the prices shown in Exhibit B of this Agreement. These
                 prices are consistent with those given to MTI's international
                 distributors. MTI reserves the right to adjust prices from
                 time to time, but may not increase prices more than two times
                 per

                 MTI also reserves the right to cancel any order placed by the

                 required Annual Goals in accordance with Section 1(b(iv)
                 hereof or fails to purchase the required First 180-day Goal or
                 Second 180-day Goal amounts at any time,  MTI may terminate
                 this Agreement, at its sole discretion, by providing the
                 Distributor with thirty (30) days advance written notice of
                 its intent to terminate this Agreement.

         c.      Default.  If, during the term of this Agreement, Distributor
                 defaults in the performance of any of its other obligations
                 under this Agreement, or any of the representations or
                 warranties made by Distributor are determined to be untrue,
                 MTI may give Distributor notice of default and if Distributor
                 fails to cure such default within thirty (30) days (or if such
                 default cannot be cured within thirty (30) days,  no diligent
                 effort has been made to cure such default), this Agreement
                 shall be deemed terminated as of the end of such ninety (90)
                 day period without any further action on the part of MTI .
                 Distributor will then accept no further orders for the
                 Products from the Territory and MTI shall have no further
                 obligations to Distributor hereunder.

         d.      Insolvency.  This Agreement will automatically terminate if
                 either party should become bankrupt, insolvent, or cease to do
                 business, or make an assignment for the benefit of creditors.

         e.      Competition This Agreement shall automatically terminate in
                 the event that the Distributor breaches any of the covenants
                 against competition contained in Sections 3.e. and 3.f.(i)
                 hereof;

                 Distributor breaches the sales covenants contained in Section

                 3.g.(ii) hereof.

         g.      No Waivers. The failure of MTI to terminate this Agreement
                 pursuant to any of the subparagraphs in this Section
                 shall not be considered to be a waiver by MTI of its right to
                 terminate this Agreement in the future pursuant to this
                 section for such default or any similar default.

         h.      Repurchase.  In the event of termination of this Agreement by

                 and taxes on the shipment thereof to the Distributor, any MTI
                 Products at the Distributor's place of business or in the
