(c)    All amounts required to be paid pursuant to this Article 7 shall be paid promptly in immediately available funds by wire transfer to a bank account designated by the indemnified party.

Section 7.03.    Tax Covenants. Each Buyer covenants that it shall not cause or permit the Companies or any Affiliate of either Buyer:

(a)    to take any action on the Closing Date other than in the Ordinary Course of Business, including but not limited to the distribution of any dividend or the effectuation of any redemption that could give rise to any Tax liability or reduce any Tax Asset of the Subsidiary Sellers or give rise to any loss of the Subsidiary Sellers under this Agreement; or

(b)    without the prior written consent of each of the Sellers (such consent not to be unreasonably withheld) (i) to make or change any Tax election; (ii) to amend, or request or permit the amendment of, or make or lodge any objection or appeal in relation to any Tax Returns contemplated in Section 7.05(d); (iii) apply to any Tax Authority for any binding or non-binding opinion, ruling or other determination in relation to any act, matter or transaction covered by any such Tax Returns or to any act, matter or transaction occurring on or before the Balance Sheet Date; or (iv) furnish to any Tax Authority any information (in writing or otherwise) in relation to any such Tax Returns or to any act, matter or transaction occurring on or before the Balance Sheet Date.

Without limitation on the foregoing, for the period after Closing and through the close of each such Company’s then current taxable year (as defined in the Code), Buyers shall not cause or permit such Company to engage in the following prohibited transactions:

(i)    declare or pay a dividend unless required by the terms of the Candelaria Shareholders’ Agreement or the Ojos Shareholders’ Agreement;

(ii)    make or cause to be made any investment in U.S. property within the meaning of Section 956 of the Code; or

(iii)     conduct business outside the Ordinary Course of Business or engage in any transaction outside the Ordinary Course of Business (in either case based upon the Company’s historic activities) if such business or activities would reasonably be expected to impact (1) the amount or character of the Subsidiary

Sellers’ gross income reportable under Section 1248 of the Code; (2) the amount of the Subsidiary Sellers’ associated deemed-paid foreign taxes within the meaning of Section 902 of the Code that are associated with the Section 1248 inclusion; or (3) the amount of Subsidiary Sellers’ subpart F income within the meaning of Section 952 of the Code.

Section 7.04.    Tax Returns.

(a)    Freeport shall file or cause to be filed, when due (taking into account any extension of a required filing date), all Tax Returns with respect to the Companies that are required to be filed on or prior to the Closing Date and timely cause the Companies to pay all Taxes shown as due on such Tax Returns. With respect to Tax Returns that relate to the Post-Balance Sheet Tax Period, any Tax Return shall be prepared in a manner consistent with past practice and without a change of any election or any accounting method (unless otherwise required by applicable law). Such Tax Returns shall be submitted by Freeport to Buyers (together with schedules, statements and, to the extent reasonably requested by Buyers, supporting documentation) at least 30 days prior to the due date (including any applicable extension) of such return. With respect to Tax Returns that relate to the Post-Balance Sheet Tax Period, Buyers shall have the right to review and comment on such Tax Returns, and such returns shall reflect Buyers' reasonable comments.

(b)    Buyers shall file, or cause to be filed, when due (taking into account any extensions of a required filing date), all Tax Returns for Income Taxes with respect to the Companies that are required to be filed with any taxing authority by either of the Companies after the Closing Date with respect to a Pre-Balance Sheet Tax Period or a Straddle Tax Period (each a “Buyer-Filed Income Tax Return”). Any Buyer-Filed Income Tax Return shall be prepared in a manner consistent with past practice and without a change of any election or any accounting method (unless otherwise required by applicable law). Buyer-Filed Income Tax Returns shall be submitted by Buyers to Freeport (together with schedules, statements and, to the extent reasonably requested by Freeport, supporting documentation) at least 30 days prior to the due date (including any applicable extension) of such return. Freeport shall have the right to review and comment on such Buyer-Filed Income Tax Return, which shall not be filed without Freeport’s consent, which consent shall not be unreasonably withheld.

(c)    If Freeport, within ten Business Days after receipt of any such Buyer-Filed Income Tax Return, notifies Buyers in writing that it objects to any items in such return, the disputed item shall be resolved in a manner mutually agreeable to both parties, and if not so resolved, then by a jointly retained nationally recognized accounting firm, who shall not have any material relationship with Buyers, Sellers, Subsidiary Sellers or their Affiliates (an “Accounting Referee”) within a reasonable time, taking into account the deadline for filing such return. Upon resolution of all such items, the relevant Buyer-Filed Income Tax Return shall be adjusted to reflect such resolution and shall be binding upon the parties without further adjustment. The costs, fees and expenses of such Accounting Referee shall be borne equally by Buyers, on the one hand, and Freeport, on the other hand. Neither Company shall amend any Tax Return with respect to Income Tax for a Pre-Balance Sheet Tax Period or a Straddle Tax Period without the prior written consent of Freeport, such consent not to be unreasonably withheld.

(d)    Buyers shall pay or cause to be paid to the appropriate Taxing Authority all Taxes with respect to any Buyer-Filed Income Tax Return filed under this Article in accordance with Applicable Law. To the extent the amount of any Pre-Balance Sheet Taxes shown as due and payable on any Buyer-Filed Income Tax Return prepared in compliance with this Article, exceeds the amount, if any, of such Taxes reflected as a liability in the relevant Balance Sheet, (i) Freeport shall pay to the applicable Buyer(s), without set-off or deduction, an amount equal to 80% of such excess within ten days after request therefore by the Buyers by submission of an invoice to Freeport evidencing such payment and a statement showing the allocation to Pre-Balance Sheet Taxes and (ii) if the SMMA Participant has exercised the Candelaria Tag-Along Right and the Ojos Tag-Along Right, the Tag-Along Sellers shall pay to the applicable Buyer(s), without set-off or deduction, an amount equal to 20% of such excess within ten days after request therefore by the Buyers by submission of an invoice to the Tag-Along Sellers evidencing such payment and a statement showing the allocation to Pre-Balance Sheet Taxes.

(e)    The parties hereto will, to the extent permitted by Applicable Law, elect with the relevant Taxing Authority to treat a portion of any Straddle Tax Period as a short taxable period ending as of the close of business on the Closing Date.

(f)    Except as provided in this Section, Freeport will be entitled to 80%, and, if the SMMA Participant has exercised the Candelaria Tag-Along Right and the Ojos Tag-Along Right, the Tag-Along Sellers shall be entitled to 20%, of any refunds (including interest received thereon) in respect of any Pre-Balance Sheet Tax Period net of any income taxes imposed thereon, except to the extent any such refund was taken into account as a current asset in the relevant Balance Sheet. Nothing in this Section will preclude the Companies from making an election under Section 172(h) of the Code or any comparable provision of Tax law or regulations for any taxable year beginning after the Closing Date.

(g)    Buyers shall pay to each Seller any refund to which it is entitled pursuant to paragraph (f) of this Section no later than ten days following receipt of such refund, net of any income taxes imposed thereon. If any Pre-Balance Sheet Income Tax paid by any Seller, the Companies, Subsidiary Sellers or any predecessor or Affiliate thereof has the

effect of reducing any Tax liability with respect to a Post-Balance Sheet Tax Period, Buyers or the Companies shall promptly pay or cause to be paid to Freeport 80%, and, if the SMMA Participant has exercised the Candelaria Tag-Along Right and the Ojos Tag-Along Right, to the Tag-Along Sellers 20%, of the amount of such reduction in Tax liability when either Buyer, any Affiliate of either Buyer or the Companies are entitled thereto, net of any income taxes imposed thereon, except to the extent any such credit or reduction in Tax liability was taken into account as a current asset in the relevant Balance Sheet. Unless such treatment is contrary to Applicable Law, the parties agree that any amounts paid to either of the Sellers pursuant to paragraphs (f) and (g) of this Section will be treated as an adjustment to the Purchase Price for Chilean tax law purposes.

(h)    If Buyers notify Sellers in writing that the Companies have become entitled to a refund of Taxes described above, and such refund (or any portion thereof) is attributable solely to the carryback of losses, credits or similar items of the Companies, as the case may be, from a Post-Balance Sheet Tax Period, the Companies will file a claim for a refund with respect to such losses, credits or similar items and the Companies will be entitled to retain the amount of any such refund received (together with interest thereon).

(i)    Except as provided in paragraphs (f) and (g) of this Section 7.04, the Companies will be entitled to any refunds (including any interest received thereon), in respect of any federal, state, local or foreign Tax liability of the Companies.

(j)    Notwithstanding anything to the contrary in this Agreement, all Transfer Taxes incurred in connection with the transactions contemplated by this Agreement shall be borne by Buyers. Buyers will, at their own expense, file all necessary Tax Returns with respect to all such Transfer Taxes, and, if required by Applicable Law, each Seller will join in the execution of any such Tax Returns.

Section 7.05.    Cooperation on Tax and Accounting Matters.

(a)    In the case of any audit, claim for refund, or administrative or judicial proceeding involving any asserted Tax liability or refund with respect to the Companies (any such audit, claim for refund, or proceeding relating to an asserted Tax liability referred to herein as a “Contest”) after the Closing Date that relates solely to Pre-Balance Sheet Taxes, Freeport shall control the conduct of such Contest, but Buyers shall have the right to participate in such Contest at Buyers’ own expense, and Freeport shall not be able to settle, compromise and/or concede any portion of such Contest that is reasonably likely to affect the Tax liability of the Companies for any taxable year (or portion thereof) beginning after the Balance Sheet Date without the consent of Buyers, which consent shall not be unreasonably withheld, delayed or conditioned; provided, that, with respect to any such Contest, if Freeport notifies Buyers that it does not intend to pursue the Contest following the receipt by Freeport of notice of such Contest, Buyers shall have the right to assume control of such Contest and shall be able to settle, compromise and/or concede such Contest in Buyers’ sole discretion.

(b)    In the case of a Contest after the Closing Date that relates to a Straddle Tax Period Buyers shall control the conduct of such Contest, but Freeport shall have the right to participate in such Contest at its own expense, and Buyers shall not settle, compromise and/or concede such Contest without the consent of Freeport, which consent shall not be unreasonably withheld, delayed or conditioned.

(c)    Buyers and each Seller agree to furnish or cause to be furnished to each other, upon request, as promptly as practicable, such information and assistance relating to the Companies (including access to books and records) as is reasonably necessary for the filing of all Tax Returns (including any report required pursuant to Section 6043A of the Code and all Treasury Regulations promulgated thereunder), the making of any election relating to Taxes, the preparation for any Contest, and the prosecution or defense of any claim, suit or proceeding relating to any Tax. Buyers and each Seller shall reasonably cooperate with each other in the conduct of any Contest or other proceeding involving or otherwise relating to the Companies (or their income or assets) with respect to any tax and each shall execute and deliver such powers of attorney and other documents as are necessary to carry out the intent of this Section 7.05(c). Any information obtained under this Section 7.05(d) shall be kept confidential, except as may be otherwise necessary in connection with the filing of Tax Returns or in the conduct of a Contest or other Tax proceeding.

(d)    Buyers and each Seller shall (i) retain all books and records with respect to Taxes pertaining to the Companies for a period of at least six years following the Closing Date and abide by all record retention agreements entered into with any Taxing Authority for all periods required by such Taxing Authority; and (ii) provide the other party with at least 30 days’ prior written notice before destroying any such books and records, during which period the party receiving the notice can elect to take possession, at its own expense, of such books and records.

Section 8.01.    Continuing Employees. (a) Prior to the Closing, the Buyers shall, or shall cause a Company to, make an offer of employment to each Specified Service Provider on terms consistent with those provided under this Section 8.01. In addition, as of the Closing Date, Buyers shall cause the Companies to continue the employment of all Company Employees provided that it is understood that the foregoing statement does not constitute a guarantee of continued employment. As of the Closing, or such other later date as set forth in the Transition Services Agreement, the Company Employees who are employed by the Companies and the Specified Service Providers who have accepted employment with a Company (the “Continuing Employees”) shall cease to be covered by the employee benefit plans of Freeport and its Affiliates (which, for the avoidance of doubt, shall not include the Companies from and after the Closing) and instead shall be covered by the employee benefit plans of a Buyer or its Affiliates, including, commencing on the Closing Date, the Companies, as applicable. In addition to any obligation either Buyer or its Affiliates may have under Applicable Law, for the period

beginning on the Closing Date and continuing through the first anniversary of the Closing Date, Buyers shall, or shall cause the Companies to, provide the Continuing Employees, to the extent that the Continuing Employees remain so employed, with (i) fixed cash compensation that is no less favorable than the compensation of each such Continuing Employee immediately prior to the Closing Date, (ii) incentive compensation opportunities comparable to those provided to each such Continuing Employee immediately prior to the Closing Date and (iii) benefits (including severance) substantially comparable in the aggregate to the benefits (including severance) provided by the Companies to each such Continuing Employee immediately prior to the Closing Date.

(b)    Prior to the Closing, each Company shall assume all liabilities related to Company Employees and Specified Service Providers set forth opposite such Company’s name in Section 8.01(b) of the Companies Disclosure Schedule.

Section 8.02.    Buyer Plans. In addition to any obligation either Buyer or its Affiliates may have under Applicable Law:

(a)    With respect to any employee benefit plan maintained by either Buyer or its Affiliates in which any Continuing Employee becomes a participant, for purposes of determining eligibility to participate, vesting and benefit accrual (other than benefit accrual under a defined benefit pension plan of such Buyer or its Affiliates), each Continuing Employee’s service with Freeport, the Companies and any of their respective Affiliates (as well as service with any predecessor employer, to the extent service with the predecessor employer is so recognized) shall be treated as service with such Buyer and its Affiliates; provided, however, that such service need not be recognized to the extent that such recognition would result in any duplication of benefits.

(b)    Each Buyer shall waive, or shall cause its Affiliates to waive, unless legally unable to do so, any preexisting conditions, limitations, exclusions, actively-at-work requirements and waiting periods under any welfare benefit plan maintained by such Buyer or any of its Affiliates in which Continuing Employees (and their eligible dependents) will be eligible to participate from and after the Closing Date. Each Buyer shall recognize, or shall cause its Affiliates to recognize, all co-payments, deductibles and similar expenses and out-of-pocket maximums incurred by each Continuing Employee (and his or her eligible dependents) prior to the Closing Date for purposes of satisfying any analogous deductible and co-payment limitations and out-of-pocket requirements under the relevant welfare benefit plans in which such Continuing Employee (and his or her eligible dependents) will be eligible to participate from and after the Closing Date.

Section 8.03.    No Third-Party Beneficiaries. Without limiting the generality of Section 12.09, no provision of this Article 8, express or implied: (a) is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person (including, without limitation, any Continuing Employees and any dependent or beneficiary thereof) other than the parties hereto and their respective successors and permitted assigns, (b) shall constitute an amendment of, or an undertaking to amend, any Employee Benefit Plan or any employee benefit plan, program or arrangement

maintained by Freeport, Buyers or any of their respective Affiliates or (c) is intended to prevent either Buyer or its Affiliates from amending or terminating any Employee Benefit Plan in accordance with its terms.

Section 9.01.    Conditions to Obligations of Buyers and Sellers. The obligations of Buyers and Sellers to consummate the Closing are subject to the satisfaction of the following conditions:

(a)    No provision of Applicable Law or any Governmental Authority having competent jurisdiction shall prohibit the consummation of the Closing, no judgment, injunction, order or decree issued by any Governmental Authority having competent jurisdiction shall prohibit the consummation of the Closing and no proceeding or lawsuit shall be pending by any Governmental Authority having competent jurisdiction for the purpose of obtaining any injunction, order or decree prohibiting the consummation of the Closing; and

(b)    The parties shall have received all consents, authorizations or approvals from the Governmental Authorities set forth in Schedule 9.01(b).

Section 9.02.    Conditions to Obligation of Buyers. The obligation of Buyers to consummate the Closing is subject to the satisfaction of the following further conditions:

(b)    Buyers shall have received all documents they may reasonably request from each Seller, the Subsidiary Sellers, and the Companies relating to the existence of such Seller, the Subsidiary Sellers and the Companies and the authority of Freeport for the Transaction Agreements, all in form and substance reasonably satisfactory to Buyers; and

(c)    Each Seller shall deliver a certificate, reasonably satisfactory to Buyers, to the effect that no powers of attorney granted by the Companies to such Seller and/or its respective Affiliates and/or members of the Administration Committee or any subcommittee thereof remain outstanding.

Section 9.03.    Conditions to Obligation of Sellers. The obligation of each Seller to consummate the Closing is subject to the satisfaction of the following additional conditions:

(a)    (i) Buyers shall have performed in all material respects all of their obligations hereunder required to be performed by Buyers at or prior to the Closing Date, (ii) the representations and warranties of Buyers contained in this Agreement and in any certificate or other writing delivered by Buyers pursuant hereto shall be true in all material respects at and as of the Closing Date, as if made at and as of such date, and (iii) Sellers shall have received a certificate signed by an officer of each Buyer to the foregoing effect; and

(b)    Each Seller shall have received all documents it may reasonably request from Buyers relating to the existence of Buyers and the authority of Buyers for this Agreement, all in form and substance reasonably satisfactory to such Seller.

The representations and warranties of the parties hereto contained in this Agreement or in any certificate or other writing delivered pursuant hereto or in connection herewith shall survive the Closing for a period of 18 months following the Closing Date; provided that the representations and warranties of Sellers in Sections 3.01, 3.02 and 3.06 (the “Seller Fundamental Representations”) and the representations and warranties of Buyers in Sections 4.01 and 4.03 (the “Buyer Fundamental Representations”) shall survive the Closing until the expiration of the applicable statute of limitations; provided further that the representation and warranty of Sellers in Section 3.12 shall survive the Closing for a period of 90 days. The covenants and agreements of the parties hereto contained in this Agreement or in any certificate or other writing delivered pursuant hereto or in connection herewith shall survive the Closing indefinitely or for the shorter period explicitly specified therein, except that for such covenants and agreements that survive for such shorter period, breaches thereof shall survive indefinitely or until the latest date permitted by law; provided that the covenants and agreements of Freeport in Sections 2.03 and 5.02, including breaches thereof, shall survive the Closing for a period of 90 days. Notwithstanding the foregoing, any breach of representation, warranty, covenant or agreement in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate pursuant to the foregoing, if notice of the inaccuracy or breach thereof giving rise to such right of indemnity shall have been given to the party against whom such indemnity may be sought prior to such time.

Section 10.02.    Indemnification. (a) Effective at and after the Closing, each Seller hereby, severally and not jointly, indemnifies Buyers and their Affiliates (including, following the Closing, the Companies) against and agrees to hold each of them harmless from (x) any and all damage, loss and expense (including reasonable expenses of investigation and reasonable attorneys’ fees and expenses in connection with any action,

suit or proceeding) (“Damages”) actually suffered by Buyers or any of their Affiliates arising out of the failure of any representation or warranty made by such Seller in this Agreement to be true and correct on and as of the date hereof or, in the case of the Closing Date Representations only, the Closing Date (or with respect to any representation or warranty that is made as of a specific date, the failure of such representation or warranty to be true and correct as of such date) (each such failure, a “Seller Warranty Breach”) or breach of covenant or agreement made or to be performed by such Seller pursuant to this Agreement, other than any Damages arising out of any Specified Matter (as defined in Schedule 10.02), and (y) Specified Matter Indemnifiable Costs (as defined in Schedule 10.02); provided that with respect to indemnification by any Seller for Seller Warranty Breaches pursuant to clause (x) of this Section 10.02(a) (other than Seller Warranty Breaches in respect of the Seller Fundamental Representations), (i) no Seller shall be liable with respect to any individual claim unless the Damages with respect to the underlying Seller Warranty Breach (or series of related Seller Warranty Breaches) exceeds US$200,000, (ii) no Seller shall be liable unless the aggregate amount of Damages with respect to all Seller Warranty Breaches, disregarding any Damages for which no Seller is liable pursuant to clause (i), exceeds (A) if the SMMA Participant does not exercise the SMMA Candelaria Tag-Along Right and does not exercise the SMMA Ojos Tag-Along Right, US$18,000,000 or (B) if the SMMA Participant exercises the SMMA Candelaria Tag-Along Right and the SMMA Ojos Tag-Along Right, US$22,500,000, and then only to the extent of such excess and (iii) Sellers’ maximum liability for all such Seller Warranty Breaches shall not exceed (A) if the SMMA Participant does not exercise the SMMA Candelaria Tag-Along Right and does not exercise the SMMA Ojos Tag-Along Right, US$270,000,000 or (B) if the SMMA Participant exercises the SMMA Candelaria Tag-Along Right and the SMMA Ojos Tag-Along Right, US$337,500,000; provided, further, that each Seller’s maximum liability for all such Seller Warranty Breaches (including in respect of the Seller Fundamental Representations) and for all Specified Matter Indemnifiable Costs, shall not exceed such Seller’s Allocable Share of the Base Purchase Price. Notwithstanding the foregoing, (i) the sole remedy for any Seller Warranty Breach of Section 3.12 or any breach of Section 2.03 or Section 5.02 shall be as set forth in Section 2.03, and neither Buyer nor any of its Affiliates shall be entitled to indemnification therefor and (ii) neither Seller shall have any indemnification obligation with respect to any Seller Warranty Breach of any representation or warranty in respect of, or any breach of any covenant or agreement of, the other Seller or such other Seller’s Subsidiary Sellers, and each Seller’s indemnification liability with respect to any Seller Warranty Breach of any representation or warranty in respect of the Companies and with respect to any Specified Matter Indemnifiable Costs shall be limited to such Seller’s Allocable Share of the Damages or Specified Matter Indemnifiable Costs for which indemnification is owed in accordance with this Article 10.

(b)    Effective at and after the Closing, Buyers hereby indemnify Sellers, the Subsidiary Sellers and their respective Affiliates against and agrees to hold each of them harmless from any and all Damages actually suffered by any Seller, the Subsidiary Sellers or any of their respective Affiliates arising out of the failure of any representation or warranty made by Buyers in this Agreement to be true and correct on and as of the

date hereof or the Closing Date (or with respect to any representation or warranty that is made as of a specific date, the failure of such representation or warranty to be true and correct as of such date) (each such failure, a “Buyer Warranty Breach”) or breach of covenant or agreement made or to be performed by either Buyer pursuant to this Agreement; provided that with respect to indemnification by Buyers for Buyer Warranty Breaches pursuant to this Section (other than Buyer Warranty Breaches in respect of the Buyer Fundamental Representations), (i) Buyers shall not be liable with respect to any individual claim unless the Damages with respect to the underlying Buyer Warranty Breach (or series of related Buyer Warranty Breaches) exceeds $200,000, (ii) Buyers shall not be liable unless the aggregate amount of Damages with respect to such Buyer Warranty Breaches, disregarding any Damages for which Buyers are not liable pursuant to clause (i), exceeds (A) if the SMMA Participant does not exercise the SMMA Candelaria Tag-Along Right and does not exercise the SMMA Ojos Tag-Along Right, US$18,000,000 or (B) if the SMMA Participant exercises the SMMA Candelaria Tag-Along Right and the SMMA Ojos Tag-Along Right, US$22,500,000, and then only to the extent of such excess and (iii) Buyers’ maximum liability for all such Buyer Warranty Breaches shall not exceed (A) if the SMMA Participant does not exercise the SMMA Candelaria Tag-Along Right and does not exercise the SMMA Ojos Tag-Along Right, US$270,000,000 or (B) if the SMMA Participant exercises the SMMA Candelaria Tag-Along Right and the SMMA Ojos Tag-Along Right, US$337,500,000; provided, further, that Buyers’ maximum liability for all such Buyer Warranty Breaches (including in respect of the Buyer Fundamental Representations) shall not exceed the Base Purchase Price paid by Buyers.

Section 10.03.    Third Party Claim Procedures. (a) The party seeking indemnification under Section 10.02 (the “Indemnified Party”) agrees to give prompt notice in writing to the party against whom indemnity is to be sought (the “Indemnifying Party”) of the assertion of any claim or the commencement of any suit, action or proceeding by any third party (a “Third Party Claim”) in respect of which indemnity may be sought under such Section. Such notice shall set forth in reasonable detail such Third Party Claim and the basis for indemnification (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have actually prejudiced the Indemnifying Party.

(b)    The Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and, subject to the limitations set forth in this Section, shall be entitled to control and appoint lead counsel for such defense, in each case at its own expense (it being understood that Freeport shall be entitled to control the defense of any Third Party Claims with respect to which indemnification is sought from all Sellers). Notwithstanding the foregoing sentence, Buyers and their Affiliates shall control and appoint lead counsel for the defense of any Specified Matter subject to Section 10.06 below.

(c)    If the Indemnifying Party shall assume the control of the defense of any Third Party Claim in accordance with the provisions of this Section 10.03, (i) the Indemnifying Party shall obtain the prior written consent of the Indemnified Party (which

shall not be unreasonably withheld) before entering into any settlement of such Third Party Claim, if the settlement does not fully and unconditionally release the Indemnified Party and its Affiliates from all liabilities and obligations with respect to such Third Party Claim or the settlement imposes injunctive or other equitable relief against the Indemnified Party or any of its Affiliates and (ii) the Indemnified Party shall be entitled to participate in the defense of any Third Party Claim and to employ separate counsel of its choice for such purpose. The fees and expenses of such separate counsel shall be paid by the Indemnified Party.

(d)    Each party shall cooperate, and cause their respective Affiliates to cooperate, in the defense or prosecution of any Third Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith.

Section 10.04.    Direct Claim Procedures. In the event an Indemnified Party has a claim for indemnity under Section 10.02 against an Indemnifying Party that does not involve a Third Party Claim, the Indemnified Party agrees to give prompt notice in writing of such claim to the Indemnifying Party. Such notice shall set forth in reasonable detail such claim and the basis for indemnification (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have actually prejudiced the Indemnifying Party.

Section 10.05.    Calculation of Damages. (a) The amount of any Damages payable under Section 10.02 by the Indemnifying Party shall be net of any (i) amounts actually recovered by the Indemnified Party under applicable insurance policies or from any other Person alleged to be responsible therefor, and (ii) Tax benefit actually realized by the Indemnified Party arising from the incurrence or payment of any such Damages. Each Indemnified Party shall use reasonable best efforts to collect any amounts available under insurance coverage, or from any other Person alleged to be responsible, for any Damages payable under Section 10.02. If the Indemnified Party receives any amounts under applicable insurance policies, or from any other Person alleged to be responsible for any Damages, subsequent to an indemnification payment by the Indemnifying Party, then such Indemnified Party shall promptly reimburse the Indemnifying Party for any payment made or expense incurred by such Indemnifying Party in connection with providing such indemnification payment up to the amount received by the Indemnified Party, net of any expenses incurred by such Indemnified Party in collecting such amount, and without interest.

(b)    The Indemnifying Party shall not be liable under Section 10.02 for (i) any Damages reflected as a liability in the relevant Balance Sheet other than with respect to Specified Matters, (ii) any matter that is the subject of Section 2.03, (iii) any consequential, special, indirect or punitive Damages (except for punitive Damages awarded against an Indemnified Party in a Third Party Claim or consequential, special or indirect damages with respect to Specified Matters), or (iv) Damages for lost profits.

(c)    In the case of any Damages suffered or incurred by the Companies (including with respect to Specified Matters), the amounts recoverable by any Indemnified Party in respect of such Damages shall be limited to 80% of the amount of such Damages, unless the SMMA Participant exercises either the SMMA Candelaria Tag-Along Right or the SMMA Ojos Tag-Along Right.

(d)    Each Indemnified Party must use commercially reasonable efforts to mitigate in accordance with Applicable Law any loss for which such Indemnified Party seeks indemnification under this Agreement. If such Indemnified Party mitigates its loss after the Indemnifying Party has paid the Indemnified Party under any indemnification provision of this Agreement in respect of that loss, the Indemnified Party must notify the Indemnifying Party and promptly pay to the Indemnifying Party the extent of the value of the benefit to the Indemnified Party of that mitigation (less the Indemnified Party’s reasonable costs of mitigation) and without interest.

Section 10.06.    Environmental Procedures. (a) Notwithstanding any other provision of this Agreement to the contrary, no Seller shall be liable under this Agreement for, and neither Buyer nor any of its Affiliates shall be indemnified for, any Damages relating to Environmental Matters to the extent such Damages: (i) arise out of any sampling, testing or other invasive investigation of the air, soil, soil gas, surface water, groundwater, building materials or other environmental media, or any disclosure, report or communication relating to any Environmental Matter to any Governmental Authority or other third Person, unless such sampling, testing, investigation, disclosure, report or communication is required by Applicable Law or is necessary to respond to any Third Party Claim against any of Buyers or their Affiliates; (ii) result from any material construction, renovation, expansion, demolition, shutdown or closure of any asset, facility or real property following the Closing; or (iii) exceed those Damages that must be incurred to satisfy, in a reasonably cost-effective manner, the minimum requirements of a Governmental Authority pursuant to applicable Environmental Law using where possible risk-based standards, engineering, use or institutional controls or deed or other restrictions.

(b)    Other than with respect to any Specified Matter (control of which is addressed in Section 10.03(b)), as between Sellers and any of Buyers or their Affiliates, Freeport shall have the right at its option to control, or cause its Affiliates to control, any Environmental Matter that is subject to indemnification under this Agreement, including the disclosure, investigation, negotiation, performance, remediation, monitoring, settlement and resolution of such matter.
