      by the Canadian Institute of Mining, Metallurgy and Petroleum which is
      incorporated into Canadian securities regulators National Instrument
      43-101 (Standards of Disclosure for Mineral Projects), being a
      comprehensive study of a range of options for the technical and economic
      viability of a mineral project that has advanced to a stage where a
      preferred mining method, in the case of underground mining, or the pit
      configuration, in the case of an open pit, is established and an effective
      method of mineral processing is determined. It includes a financial
      analysis based on reasonable assumptions on the Modifying Factors and the
      evaluation of any other relevant factors which are sufficient for a
      Qualified Person, acting reasonably, to determine if all or part of the
      Mineral Resource may be converted to a Mineral Reserve at the time of
  reporting. A Pre-Feasibility Study is at a lower confidence level than a Feasibility Study.

| | (e) | Non-arms Length Transactions.No transaction or
      arrangement between the Company and any Person with whom the Company was
      not dealing at arms length within the meaning of Tax Act involving the
      acquisition, delivery, disposition or provision of property or services or
      the right to use property or services, took place for consideration that
      is other than the fair market value for such property, services or right
      and such transaction or arrangement was made on arms length terms and

| | (f) | Tax Jurisdictions.No Governmental Authority of a
      jurisdiction in which the Company does not file Tax Returns has made any
      claim that such entity is or may be subject to taxation by such
      jurisdiction. To the Sellers knowledge, there is no basis for a claim
      that the Company is subject to Tax in a jurisdiction in which it does not
      file Tax Returns.

| | (a) | An Indemnifying Party shall have 30 days from receipt of
      the Notice of Claim (the Notice Period) to notify the Indemnified
      Party (i) whether or not the Indemnifying Party disputes the liability of
      the Indemnifying Party to the Indemnified Party hereunder with respect to
      such Notice of Claim and (ii) if applicable, whether or not it elects to
      defend the Indemnified Party against any third party action, proceeding or
      claim. In the event that the Indemnifying Party notifies the Indemnified
      Party within the Notice Period that it elects to defend the Indemnified
      Party with respect to such action, proceeding or claim, the Indemnifying
      Party shall be entitled to assume the defense or settlement thereof with
      counsel of its own choosing, and shall have the right to defend the
      Indemnified Party by appropriate proceedings, provided that such counsel
      shall be satisfactory to the Indemnified Party, acting reasonably. Subject
      to Section 8.3, all costs and expenses incurred by the Indemnifying Party
      in defending any such action, proceeding or claim shall be a liability of,
      and shall be paid by, the Indemnifying Party. If the Indemnified Party
      desires to participate in any such defense or settlement it may do so at
      its sole cost and expense, but control of such defense or settlement shall
      remain with the Indemnifying Party. Notwithstanding the foregoing, except
      with the prior written consent of the Indemnified Party, no Indemnifying
      Party, in the defense of any such action, proceeding or claim, shall
      consent to entry of any judgment or enter into any settlement that
      provides for injunctive or other nonmonetary relief affecting the
      Indemnified Party or that does not include as an unconditional term
      thereof the giving by each claimant or plaintiff to such Indemnified Party
      of a release from all liability with respect to such action, proceeding or
      claim. In the event that the Indemnified Party shall receive written
      advice of counsel that the Indemnified Party would have available to it
      one or more defenses or counterclaims that are in addition to, or
      inconsistent with, one or more of those that may be available to the
      Indemnifying Party in respect of such action, proceeding or claim or any
      litigation relating thereto, the Indemnified Party shall have the right at
      all times to take over and assume control over the defense, settlement,
      negotiations or litigation relating to any such action, proceeding or
      claim (provided such Indemnified Party shall only be entitled to one set
      of counsel in each applicable jurisdiction) and the cost thereof shall,
      subject to Section 8.3, be paid by the Indemnifying Party, provided that
      the Indemnified Party shall not settle any such action, proceeding or
      claim without the written consent of the Indemnifying Party.

      failing agreement within 10 Business Days of the demand for arbitration,

      of the arbitration, such matter shall be referred to and decided by the
      arbitrator whose decision shall be final and binding on the parties to the
