12.

Formal Agreement

If required by either party, the parties will use their best efforts to settle and execute formal documentation as necessary to give effect to this agreement in Peru within a reasonable time after such party delivers notice to the other to enter into such formal Peruvian agreement.  Such formal documentation will reflect the terms and conditions of this letter together with such additional terms and conditions as are typical of option agreements of this nature and will reflect a structure among the parties indicated to be the most beneficial by the parties' Canadian and Peruvian legal and tax advisers, but this agreement is not subject to the settlement and execution such formal documentation and is a binding agreement upon acceptance hereof by Minera.  If there are disputes with respect to the form of such formal documentation, the matter will be referred to arbitration in accordance with paragraph 13.

13.

Arbitration

Any dispute, controversy or claim arising out of or relating to this agreement, the breach, termination or invalidity of it, any deadlock or inability of the parties to agree on a course of action to be taken hereunder, or the failure of the parties to settle the formal agreement referred to in paragraph 12, will be referred to and finally resolved by arbitration in accordance with the  "Procedures for Cases under the BCICAC Rules" of the British Columbia International Commercial Arbitration Centre ("BCICAC"), which will administer the arbitration case in accordance with such rules.

The place of arbitration will be Vancouver, British Columbia, Canada and the language used in the arbitral proceeding will be English.  The arbitrator's fees, and the other costs of the arbitration, will be paid by the prevailing party, subject to the contrary decision of the arbitrator.

14.

Force Majeure

No party will be liable for its failure to perform any of its obligations under this agreement due to a cause beyond its control (except those caused by its own lack of funds) (each an "Intervening Event") including, but not limited to, acts of God, fire, flood, explosion, strikes, lockouts or other industrial disturbances, laws, rules and regulations or orders of any duly constituted governmental authority, excessive delays in obtaining, or the refusal to issue, any required permits or licenses, or non-availability of materials, supplies, labour or transportation.  All time limits imposed by this agreement will be extended by a period equivalent to the period of delay resulting from an Intervening Event.  A party relying on force majeure will take all reasonable steps to eliminate an Intervening Event and, if possible, will perform its obligations under this agreement as far as practical, but nothing herein will require such party to settle or adjust any labour dispute or to question or to test the validity of any law, rule, regulation or order of any duly constituted governmental authority.

15.

Legal and Property Title Due Diligence

This agreement is subject to the completion by Wealth of legal and title due diligence on the Property, and results therefrom satisfactory to Wealth, acting reasonably, within a period of thirty (30) days after the Execution Date.  If the results of such due diligence are not satisfactory to Wealth it may, at any time prior to the end of such thirty (30) day period, so notify Minera and thereupon this agreement will be terminated without any further obligations of either party to the other.

16.

Application to TSX Venture Exchange Inc. for Acceptance

Forthwith upon the completion by Wealth of the due diligence specified in paragraph 15 and receipt of results satisfactory to Wealth therefrom, Wealth will make application to the TSXV requesting the acceptance for filing hereof on behalf of Wealth, and will diligently pursue the obtaining of such acceptance, including arranging for the preparation of and providing all information and materials required by the TSXV in order to grant such acceptance.  Minera will co-operate with Wealth in connection therewith and will provide any information with respect to Minera or the Property as may be required by the TSXV in connection with the grant of such acceptance.
