way of the Company to fulfill any of its material obligations under this
Agreement (hereinafter "Breach"), the Consultant, after furnishing the Company
with thirty (30) days prior written notice and the opportunity to cure, shall be

      During the Term or an extended term, the Company shall be entitled, by

      breach by the Consultant of one or more of the terms of this Agreement, or

      because of the proprietary or confidential information to be obtained by
      or disclosed to the Consultant, the Consultant covenants and agrees that
      during the term of this Agreement and for two years thereafter, he shall
      not engage in or assist others to engage in any activity which is
