         insider information on a selective basis, and public expressions of
         opinions and information respecting TIREX which a reasonable man might
         expect to result in undue trading in the stock and stock price
         variations. The Consultants expressly covenant that they will not
         knowingly contravene any Securities Law or Regulation in force in the
         United States of America in the course of providing consulting services

         activities which might be undertaken to raise funds for Tirex from
         private investors compensation for which is expressly excluded from any
         rights of inclusion under a Form S-8 Registration Statement, will not
         render them ineligible for inclusion on any S-8 filing which might be
         made by the Corporation during the course of the twelve-month period
         following the date on which the compensation shares will have been
         issued to the Consultants.

                  prior written notice of the effective date of such
                  termination.

                  of the Consultant's contract with the Corporation other than
