5.5 DUVAZ and MPC shall notify the partners of DUVAZ in the Limited Liability Mining Companies indicated in Points 5.2, 5.3 and 5.4 above, of their intention to transfer the share interests of DUVAZ in such companies, in order that said partners notify DUVAZ of their intention to exercise or not their right of first refusal, within a period of ten (10) days following the notice of MPC indicating its intention to exercise the Option pursuant to the provisions set forth in Point 4.1 of this Option Agreement. In the event that the joint ownership mentioned in Point 5.1 above, and within a period of ten (10) days following the transfer of such asset as a result of the exercise of the option established in this Option Agreement, DUVAZ and MPC shall notify the co-owners of the transfer of such aliquots. The texts of said communications and notices shall be subject to the texts forming part hereof as Appendices D, E and E-1.

Should DUVAZ fail to notify MPC that any of its partners or co-owners would have expressed their intention to enforce their right of first refusal or right of revocation, within a period of thirty (30) days after reception thereof; (A) MPC shall be entitled to offset the double value of the aforementioned Properties in respect of which it had failed to notify MPC of the answer of its co-owners with the obligations indicated in Exhibit F to the Master Agreement, as a penalty, or in the event there is no sum against which said discount can be made, (B) DUVAZ shall be bound to pay the difference until completing the full discount within the ninety (90) days following the date on which MPC had demanded DUVAZ to fulfill such payment.

If (A) DUVAZ and the Agents were unable to obtain the consents required to formalize the transfer of the Assets detailed in Points 5.2 to 5.4 hereof; and/or

(B) if, after the transfer of the Assets detailed in Point 5.1 above, the co-owners of DUVAZ exercise their right of revocation, then MPC shall be entitled to offset a sum corresponding to the value of the aforementioned Assets with any outstanding debt of Exhibit F to the Master Agreement, which are not transferred to MPC (in accordance with the values to be established in this Article) or in the event that there is no sum against which such discount can be made, DUVAZ shall be bound to pay the difference until completing the full discount. Said reimbursement shall be made in a term of no more than ninety (90) days after the exercise of the right of first refusal or right of revocation on the part of the partners or co-owners.

Without prejudice to the foregoing, such discount shall take effect with the first payment to be made in respect of Exhibit F to the Master Agreement, following receipt of notice of the partners in companies to enforce their right of first refusal, or of the co-owners to exercise their right of revocation. If the first payment was insufficient to cover the aforementioned discount, it shall take effect with the following payments until completing the amount of discount or failing that, DUVAZ shall be bound to pay MPC the difference until completing the full discount.

In other words and by way of example, if the share interest of S.M.R.L. GRANCERO DE HUANCAYO could not be transferred, MPC shall be exempted from making the payment of the installment(s) indicated in Exhibit F to the Master Agreement until completing the amount of such discount contemplated for such Assets, or failing that, DUVAZ shall be bound to pay MPC the difference until completing the full discount.

It shall be understood that in the event that the “Calabaza” mining concession, under a system of co-ownership, and therefore, its co-owners having rights of revocation in respect of transfer of aliquots, MPC shall be authorized to make the aforementioned discount (and/or DUVAZ shall be bound to pay MPC a sum equivalent to the value of such ideal shares) to that extent that any of the co-owners exercises its right of revocation, regardless of the occasion the demand of right of revocation is notified and provided that it has been filed within the term for the exercise of the right of revocation established in the Civil Code.

It is hereby understood between the parties that the eventual non-compliance of the party exercising the right of revocation or right of first refusal with the obligations assumed before DUVAZ or the Agents shall not give rise to any claim against MPC, whose obligation shall be reduced to the amount corresponding to each Asset for which the right of first refusal or right of revocation would have been exercised, considering the obligation to pay the installments of Exhibit F to the Master Agreement. extinguished, which would have been subject to the aforementioned discount, without prejudice to the provisions set forth in the next paragraph.

Without prejudice to the foregoing, it is also understood that in the event of non-compliance of the parties exercising the right of first refusal or right of

revocation, with the obligations assumed before DUVAZ in respect of such exercise, and said non-compliance gave rise to: (i) the termination of the agreement for the transfer of the share interests and the filing of such termination in filing entries corresponding to the pertinent mining companies or concessions; or (ii) an agreement between DUVAZ and the partners or co-owners is reached stating that the exercise of the right of first refusal or right of revocation is null and void; MPC shall acquire the Assets subject matter of said termination, bearing in such case the outstanding payment, to the extent that the amount already paid would not have to be subject to reimbursement on the part of DUVAZ. In such case, the payment shall be made by assigning it to the payments of Exhibit F to the Master Agreement that MPC would have made up to a value equivalent to the transferred Asset.

For the purposes of calculating the price and obligation of DUVAZ referred to in the second paragraph of Point 5.5, the value of the Assets outlined in Points 5.1 to 5.4 shall be as follows:

a) In the event of the concession named “Calabaza”, the value agreed by the parties to be assigned to the 33.33% amounts to US$945,400 (Nine Hundred Forty Five Thousand Four Hundred US Dollars).

b) In the event of the share interests of SOCIEDAD MINERA DE RESPONSABILIDAD LIMITADA GRANCERO DE HUANCAYO, owned by DUVAZ (company holder of the concessions named “Grancero” and “Lola”), the value agreed by the parties to be assigned amounts to US$1,988,600 (One Million Nine Hundred Eighty Eight Thousand Six Hundred US Dollars).

c) In the event of the concession named “Pobre Diablo”, the value agreed by the parties to be assigned to the 20% amounts to US$326,000 (Three Hundred Twenty Six Thousand US Dollars).

In order to avoid any doubt, any payments made by MPC to the creditors of Exhibit F to the Master Agreement shall be assigned as follows: (a) US$4,160,000 (Four Million One Hundred Sixty Thousand US Dollars) shall be the consideration to be paid for the transfer of the Properties outlined in Section 2.2.2 to the Master Agreement, (b) US$3,260,000 (Three Million Two Hundred and Sixty Thousand US Dollars) shall be the consideration to be paid for the

transfer of the Assets indicated in Points 5.1 and 5.4 and (c) the remaining amount shall be the consideration to be paid for the execution of the Option Agreement (which shall be then assigned to the price for the transfer of the Assets Indicated in Exhibit A, in the event of exercising the Option).

6.2 The parties hereto expressly agree that any payments made by MPC to DUVAZ’s creditors in compliance with the Schedule of Payments attached to the Master Agreement as Exhibit F may not be considered to be an assignment of the position as creditor in favor of MPC nor shall they generate any reimbursement obligation for MPC.

6.3 This obligation assumed by MPC shall constitute part of the consideration for the transfer of the Assets in the event that MPC decides to exercise the Option, and shall remain in full force and effect until the notice referred to Point 8.2 of Article Eight hereof takes effect.

EIGHT: Formalities and Consequences of Failure to Exercise the Option

8.1 If MPC notifies DUVAZ of its decision not to exercise the Option and the Stock Purchase Agreement is still in force, this fact shall not affect the validity or enforceability of MPC’s obligation to pay off, on account of DUVAZ and without

any reimbursement obligation for it, the obligations listed in the Schedule of Payments attached to the Master Agreement as Exhibit F. In these cases, the Option Agreement shall remain in full force and effect with respect to all the obligations related to the payment by MPC of the obligations listed in said Exhibit F to the Master Agreement. In this case, the payments made by MPC until that time, in compliance with the Exhibit F to the Master Agreement, as well as those to be made in respect of the same, shall be considered as a penalty in favor of DUVAZ for the non transfer of the Assets. In the case provided for in this point, the notice of MPC informing on its decision not to exercise the Option shall take effect immediately.

8.2 If, concurrently with the notice informing on its decision not to exercise the Option, MPC also notifies the CENTENARIO Class “A” Shareholders of its decision to terminate the Stock Purchase Agreement, the following consequences shall take place:

(i) Any and all credit rights of MPC before DUVAZ or CENTENARIO shall be assigned, under gratuitous title, to the Agents or their designees. To that purpose, MPC commits itself to have previously complied with its obligations (including any outstanding obligation) under the agreements executed to acquire title to said credit rights.

(ii) MPC shall formalize the transfer of one hundred percent (100%) of the shares issued by CENTENARIO in favor of the CENTENARIO Class “A” Shareholders, pursuant to the terms and conditions foreseen in the Stock Purchase Agreement.

(iii) Once the conditions described in points (i) and (ii) above have been met, the notice of MPC informing on its decision not to exercise the Option shall take effect, so that this Option Agreement shall be automatically terminated and, MPC shall not be obliged to pay the unaccrued balance of the Schedule of Payments attached to the Master Agreement as Exhibit F. The refusal of the Agents, CENTENARIO Class “A” Shareholders, DUVAZ or their designees to formalize the acts indicated in points (i) and (ii) above, shall be considered as if such conditions are met.

In this case, the parties expressly place on record that MPC shall not have any right to claim DUVAZ or the Agents any of the payments made to DUVAZ’s creditors in compliance with the Schedule of Payments attached to the Master Agreement as Exhibit F. In this case, such payments shall be considered as a penalty in favor of DUVAZ for the non transfer of the Assets.

NINE: Exercise of the Option

9.1 MPC may exercise the Option at any time during the term hereof, six (6) months in advance of the expiry of the term granted in Article Three hereof, provided

that MPC has complied with its obligation to provide DUVAZ’s creditors with the funds detailed in the Schedule of Payments attached to the Master Agreement as Exhibit F or has it subrogated DUVAZ’s position as debtor before the creditors.

9.2 Once the Option is exercised, DUVAZ binds itself to formalize the transfer of the Assets in favor of MPC. To that purpose, on the dates mentioned in the notice referred to in Point 4.2, DUVAZ and MPC shall execute the preliminary agreement and the notarially recorded instrument corresponding to the Transfer Agreement.

9.3 Furthermore, DUVAZ is under the obligation to execute any and all public or private documents required to perfect and formalize the execution of the Transfer Agreement and the filing thereof with the Public Records Office. In an effort to accelerate the filing with the Public Records Office, the parties may additionally execute the pertinent documents reflecting the transfer of each one of the Assets subject matter of the Option.

It is hereby understood between the parties that MPC shall not be bound to pay off obligations of Exhibit F to the Master Agreement up to the amount corresponding to the value assigned to the Assets mentioned in Points 5.1 to 5.4 hereof, if the partners of the limited liability mining companies holders of the concessions, or co-owners of them, exercise their right of first refusal or right of revocation and these Assets are not transferred to MPC. Likewise, MPC shall pay DUVAZ, as consideration for the execution of the Transfer Agreement, a royalty on the production extracted from such Assets, under the terms and conditions set forth in the Royalty Agreement to be entered into by and between both parties for that purpose, a sample of which is contained in Exhibit H to the Master Agreement.

10.2 If the exercise of the Option by MPC takes effect prior to the expiry of the term prescribed in Article Three hereof, in addition to the consequence foreseen in the foregoing paragraph: (i) MPC shall pay DUVAZ the projected economic cash flow of the Assets, in accordance with Exhibit J to the Master Agreement, which is attached to this Option Agreement as Exhibit C; (ii) MPC shall pay DUVAZ’s creditors the full unpaid balance of the obligations detailed in the

Schedule of Payments attached to the Master Agreement as Exhibit F, considering them extinguished, or, in any case, subrogate DUVAZ’s position as debtor before the creditors; and (iii) MPC shall pay the CENTENARIO Class ”A” Shareholders the full unpaid balance of the price of the shares issued by CENTENARIO.

In no case shall the costs related to the comprehensive Kingsmill tunnel project be deductible, except for those obligations related to this project that are attributable to DUVAZ and that are enforceable on the date the Option is exercised.

17.3 The conclusions of the baseline study and the amount that may be necessary to be deducted for DUVAZ to fulfill its obligations mentioned in the foregoing paragraph are to be notified by MPC to DUVAZ within a term not exceeding five (5) business days following receipt of said baseline study.
