        reason for delivery of a Notice of Termination;

  any of the obligations set out in clause 3 that were to become payable subsequent

  of this Agreement by reason set out in clause 8 paragraph (a), (b) (solely if
  the defaulting party is not the Vendors) and (c) (solely if such is the intent
  of the termination agreement referred thereto), the undivided 100% right, title
  and interest in and to the Mining Concessions subject matter hereof shall be
  transferred from Purchaser to Vendor, at no cost, free and clear of all liens,
  charges, encumbrances, claims, rights or interest of any person and with no
  reservation of any right or action of any kind whatsoever. To comply with such
  provision, the Purchaser covenants and agrees to execute and/or file whatever
  document, and to execute any act, that in its opinion is required, necessary
