In the event that, by reason of not having in effect the permits identified in such Disclosure Schedule 13.3(q), a closure or suspension of industrial activities of the relevant facilities is imposed by the authorities, ADS shall take (or cause to be taken) all actions that may be necessary to ensure that all purchase orders issued or outstanding during the period of such closure or suspension are duly and timely fulfilled, and shall assume and be responsible for all additional or increased costs (including shipping costs, foreign exchange differences, custom duties and any other charges) that the Company or the Chilean Subsidiary, as applicable, may suffer as a consequence of such fulfillment. In the event that ADS fails to comply with the obligations of the previous sentence, then ADS shall be responsible for all direct costs and damages arising from such failure to comply, including, for the avoidance of doubt, loss of profits, provided, however, that the Company shall take, or cause to be taken, commercially reasonable actions to mitigate any of those damages. In that event, the Parties agree that such costs and damages shall be evaluated by an expert appointed by the Parties. If any of the Parties disagrees with such evaluation, each Party will appoint another expert, and the final amount will be the average of the two closest evaluations, and the third will be discarded, provided, however, that the liability of ADS for damages under this provision shall be limited to a maximum amount equivalent to the reasonable costs (including, without limitation, any costs of termination of lease agreements, constructions and transportation) that could reasonably be incurred by relocating the facilities to a different location, plus any fines actually applied by the relevant authorities. Upon the issuance and/or transfer to the Company or the Chilean Subsidiary of the permits corresponding to the environmental, sanitary, and municipal permits specifically described in Disclosure Schedule 13.3(q), the obligations of ADS set forth in this Section 3.2(g)(iv) shall terminate and be of no further force or effect with respect to any periods thereafter.

(v) Assignment of Employee Contracts.

(A) The Parties acknowledge and agree that, upon the contribution to the capital of the Company (and the corresponding contribution to the capital of the Chilean Subsidiary) of the ADS Chilean Assets, the employment contracts of each and all of the ADS Chile Employees will automatically be transferred to the Chilean Subsidiary by virtue of law, according to the provisions of Article 4(2) of the Chilean Labor Code. Consequently, the Parties acknowledge and agree that, upon such automatic transfer, the Chilean Subsidiary will (and the Company shall cause the Chilean Subsidiary to) assume, and be subject to, all rights, obligations and liabilities as employer under such employment contracts, as if the Chilean Subsidiary had been originally a party to each of such contracts. For good administrative purposes only, the Parties agree to cause the Chilean Subsidiary to deploy reasonable efforts to obtain from each ADS Chile Employee the execution of an addendum to their employment contracts acknowledging their transfer to the Chilean Subsidiary; provided, however, that failure by any of the ADS Chile Employees to execute such addendum shall not be deemed a breach, or failure to comply with, any obligation or condition under this Agreement

(B) In connection with the transfer of employment contracts referred to in this Section 3.2(g)(v), the Parties acknowledge and agree that, according to Article 4(2) of the Chilean Labor Code, if any of the employment contracts of the ADS Chile Employees is terminated by the Company or the Chilean Subsidiary after the Initial Closing Date, then the Company or the Chilean Subsidiary, as appropriate, may potentially be under the obligation to pay to such employees a severance payment (indemnización por años de servicio) that may proportionally correspond, totally or partially, to a period of years previous to the Initial Closing Date, when such employee provided employment services to ADS (the “Pre-Closing Service Period”). Considering the foregoing, and in order to allocate to ADS the economic costs of severance payments that would proportionally correspond to the Pre-Closing Service Period, the Parties agree that if the employment contract of any of the ADS Chile Employees is terminated for business necessities or at will (under article 161 of the Chilean Labor Code) by the Company or the Chilean Subsidiary, as appropriate, and provided the Company or the Chilean Subsidiary, as appropriate, is under an obligation with such employee to pay, and in fact effectively pays, a severance compensation (indemnización por años de servicio) then ADS shall have the obligation to pay to the Company or the Chilean Subsidiary, as appropriate, an amount necessary to assume the economic costs of such portion of the severance payment that corresponds to the Pre-Closing Service Period. For calculation purposes, the Parties agree that the amount of such severance compensation for a terminated ADS Chile Employee will be equivalent to the monthly rate of remuneration paid to the relevant ADS Chile Employee during the last month of the Pre-Closing Service Period (after any legal or contractual limitation applicable for the severance payment calculation, if any) multiplied by the number of years that such employee provided employment services to ADS during the Pre-Closing Service

- 11 -

Period; provided, however, that such number of years shall not exceed the difference between (I) eleven (11) years and (II) the actual number of years (and portion exceeding six (6) months) that such employee provided employment services to the Company, or the Chilean Subsidiary, after the Initial Closing Date. This compensation shall be subject to the terms of a Special Compensation Agreement to be entered into on the Initial Closing Date by and between ADS and the Company or the Chilean Subsidiary, as appropriate, substantially on the terms attached hereto as Exhibit L.

(C) Similarly, and subject to the statutes of limitations that may be applicable under Chilean Law, the Parties agree that all labor and social security obligations and liabilities arising under the employment contracts of each and all of the ADS Chile Employees prior to the Initial Closing Date, shall be the sole responsibility of ADS. Therefore, and to the extent that any such labor or social security obligations and/or liabilities arising or accrued prior to the Initial Closing Date have not been satisfied by ADS in full, and to the extent the Company or the Chilean Subsidiary, as the case may be, is required under Chilean Law to pay or satisfy, and in fact effectively pays or satisfies, any such labor or social security obligations, then ADS shall reimburse the Company or the Chilean Subsidiary, as applicable, for such payments made promptly thereafter.

(vi) ADS Assignment and Assumption Agreement. On the Initial Closing Date, ADS shall enter into an Assignment and Assumption Agreement with the Chilean Subsidiary (the “ADS Assignment and Assumption Agreement”), pursuant to which ADS shall assign to the Chilean Subsidiary, and the Chilean Subsidiary shall assume and agree to pay or perform, those obligations and liabilities arising under the Assigned ADS Contracts on or after the Initial Closing Date. Notwithstanding the foregoing, the Parties acknowledge and agree that any insurance contracts of ADS shall only be assigned pursuant to the ADS Assignment and Assumption Agreement if such assignment can be made in a manner that results in ADS being the insured thereunder for all periods prior to the Initial Closing Date and the Chilean Subsidiary being the insured thereunder for all periods on and after the Initial Closing Date. The “Assigned ADS Contracts” shall consist of those certain contracts set forth on the ADS Assignment and Assumption Agreement, which ADS Assignment and Assumption Agreement shall include all purchase orders, insurance contracts (subject to the requirements of this Section 3.2(g)(vi)), supplier contracts, customer contracts, motor vehicle leases and other arrangements to which ADS is a party as of the Initial Closing Date.

(vii) Tigre Assignment and Assumption Agreement. On the Initial Closing Date, Tigre shall enter into an Assignment and Assumption Agreement with the Chilean Subsidiary (the “Tigre Assignment and Assumption Agreement”), pursuant to which Tigre shall assign to the Chilean Subsidiary, and the Chilean Subsidiary shall assume and agree to pay or perform, those obligations and liabilities arising under the Assigned Tigre Contracts on or after the Initial Closing Date. The “Assigned Tigre Contracts” shall consist of those certain contracts set forth in the Tigre Assignment and Assumption Agreement, which Tigre Assignment and Assumption Agreement shall include all purchase orders relating to mining applications to which Tigre is a party as of the Initial Closing Date.

(viii) Improperly Billed Items; Improperly Paid Insurance Proceeds; Unpaid Charges.

(A) The Parties agree that all obligations and liabilities under the items to be assigned or transferred by ADS and Tigre and/or assumed or obtained by the Chilean Subsidiary pursuant to this Section 3.2(g) relating to periods prior to the Initial Closing Date shall be the sole responsibility of ADS and Tigre, as the case may be, and all such obligations and liabilities relating to periods on or after the Initial Closing Date shall be the sole responsibility of the Chilean Subsidiary. In the event that the Chilean Subsidiary makes any payment with respect to any such item for or related to coverage, service, obligations or liabilities prior to the Initial Closing Date, then ADS or Tigre, as the case may be, shall reimburse the Chilean Subsidiary for such payments made promptly thereafter. In the event that ADS or Tigre, as the case may be, makes any payment with respect to any such item for or related to coverage, service, obligations or liabilities on or after the Initial Closing Date, then the Company shall cause the Chilean Subsidiary to reimburse ADS or Tigre, as the case may be, for such payments made promptly thereafter.

(B) Any unpaid obligations and/or liabilities under the items to be assigned or transferred by ADS and Tigre and/or assumed or obtained by the Chilean Subsidiary pursuant to this Section 3.2(g) to the extent such obligations and/or liabilities have not been satisfied by ADS or Tigre, as the case may be, which relate to such items for periods both before and after the Initial Closing Date (collectively, “Unpaid Charges”) shall be prorated between, on the one hand, ADS or Tigre, as the case may be, and, on the other hand, the Chilean Subsidiary, on a daily basis, with ADS or Tigre, as the case may be, being responsible for payment of all such Unpaid Charges allocable to the time period prior to the Initial Closing Date, and the Chilean Subsidiary being responsible for the payment of all such Unpaid Charges allocable to the time period on and after the Initial Closing Date. The Parties covenant and agree that all such Unpaid Charges (except to the extent reasonably disputed) shall be paid in full by either the ADS, Tigre or the Chilean Subsidiary, as the case may be, within sufficient time to prevent any Person from making any claim for or on account of any such items, including but not limited to claiming that a breach or default has occurred under the same. If either ADS or Tigre, as the case may be, on the one hand, or the Chilean Subsidiary, on the other hand, pays any such Unpaid Charges in full in accordance with the preceding sentence, then the non-paying party shall promptly reimburse such party’s pro rata portion to the paying party upon receipt of written notice of the fact and amount of such payment.

- 13 -

(ix) Nonassignable Contracts. Notwithstanding anything set forth herein or in either the ADS Assignment and Assumption Agreement or the Tigre Assignment and Assumption Agreement to the contrary, none of the items to be assigned or transferred by ADS and Tigre and/or assumed or obtained by the Chilean Subsidiary pursuant to this Section 3.2(g) shall be deemed sold, transferred or assigned to the Chilean Subsidiary if the attempted sale, transfer or assignment thereof to the Chilean Subsidiary without the consent or approval of another party or any governmental authority would be ineffective or would constitute a breach of contract or a violation of any Law or would in any other way materially and adversely affect the rights of ADS or Tigre, as the case may be (or the Chilean Subsidiary as transferee or assignee), and such consent or approval is not obtained on or prior to the Initial Closing Date. In such case, to the extent possible, (A) the beneficial interests in or to such items (collectively, the “Beneficial Rights”) shall in any event pass as of the Initial Closing Date to the Chilean Subsidiary, and (B) pending such consent or approval, the Chilean Subsidiary shall assume or discharge the liabilities of ADS or Tigre, as the case may be, related to such Beneficial Rights, as agent for ADS or Tigre, as the case may be, and ADS or Tigre, as the case may be, shall act as the Chilean Subsidiary’s agent in receipt of any benefits, rights or interests received from the Beneficial Rights associated with such items. As applicable, ADS and Tigre shall, and the Company shall cause the Chilean Subsidiary to, use reasonable best efforts (and bear their respective costs) without payment of any material fees, penalties or other amounts to any third party to obtain or secure any and all consents or approvals that may be necessary to effect the legal and valid sale, transfer or assignment of any such items. As applicable, ADS and Tigre shall, and the Company shall cause the Chilean Subsidiary to, make or complete such sales, transfers or assignments as soon as reasonably practicable and cooperate with each other in any other reasonable arrangement designed to provide the Chilean Subsidiary with the Beneficial Rights including enforcement at the cost and for the account of the Chilean Subsidiary of any and all rights of ADS or Tigre, as the case may be, against the other party thereto, and to provide for the discharge by the Chilean Subsidiary of any liability under such items.

(x) Proration. Any rents, prepaid expenses, utilities or other charges allocable to ADS or Tigre, as the case may be, on the one hand, or the Chilean Subsidiary on the other hand pursuant to this Section 3.2(g) that cannot be transferred in accordance with this Section 3.2(g) as of the Initial Closing Date shall be prorated among the parties based on the allocations therefor set forth in this Section 3.2(g).

(j) Storage of Tigre Solid Wall Inventory. If requested by the Company or the Chilean Subsidiary, Tigre shall maintain at no cost to the Company or the Chilean Subsidiary the Tigre Solid Wall Inventory at Tigre’s Lampa, Chile facility.

Any such sale shall be consummated at a price equal to the cost of the raw materials and/or products to the selling Interestholder or Affiliate plus the applicable fee set forth in the Budget for a transaction involving such raw materials or products. All such sales shall be made subject to compliance with applicable tax and legal requirements. The Business and Budget Plan shall set forth raw material/product quantity levels and fees (or methods for calculating fees) for contemplated raw materials and product sales pursuant to this Section 5.7. The combined costs and fees for any such transaction shall not exceed the prices for such raw materials and/or products that would be available on an arm’s length basis with an unrelated third party. Sales by any Interestholder or Affiliate of an Interestholder that are within the quantity level parameters and at the fees contemplated by the Budget shall not be subject to the advance disclosure requirements of Section 5.8. However, if Section 5.1(b) applies to any such sale, then the same shall be approved in accordance with the requirements of Section 5.1(b).

ARTICLE VI

TAXES

6.1 Foreign Tax Matters.

(a) Each Party may determine the foreign tax status of the Company and any Subsidiary and take all actions on behalf of the Company and any Subsidiary and to cause the Company and any such Subsidiary to take all actions that such Party determines are necessary or appropriate to obtaining or changing the foreign tax status of the Company or any such Subsidiary, provided, however, that such Party shall previously require in writing the consent of

- 38 -

the other Party to any change in such foreign tax status of the Company or any such Subsidiary, such request for consent to include a description of all actions to be taken for such purpose. The Party receiving such request for consent shall only be entitled to withhold its consent to the extent such change can reasonably be determined to create adverse tax or financial effects for such Party, the Company, or any of its Subsidiaries (supported by reasonable tax analysis materials), and the Party opposing such actions gives written notice of its opposition to the Party planning to take such actions within thirty (30) Days from the Day the consent was required in writing. If the Party receiving the request for consent does not oppose in writing to such actions within such thirty (30) Day term, then its consent shall be deemed as granted for all purposes of this Section 6.1(a). Except for opposed actions that have not yet been resolved by the Parties, each Party hereby acknowledges and agrees to take (and to cause any of its Affiliates to take) all actions that the other Party requests in connection with obtaining or changing the foreign tax status of the Company or any Subsidiary, including signing and executing any election or document that such Party determines is necessary or appropriate to obtaining or changing the foreign tax status of the Company or any Subsidiary; provided, however, that no Party need take (and need not cause any of its Affiliates to take) any action that such Party in good faith determines to be adverse to such Party, the Company or any of their respective Affiliates.

(b) It is intended that the Company initially be treated as a corporation for U.S. federal tax purposes. Accordingly, if directed by ADS, the Board shall file an election on U.S. Internal Revenue Service Form 8832 (or successor form) to classify the Company as a corporation for U.S. federal income tax purposes, effective as of the date the Company was formed, and no member of the Board, no officer of the Company nor the Company shall authorize or permit any action that revokes, changes or modifies such election without the prior written consent of ADS.

(c) If the Company’s U.S. tax status is changed to a partnership, the Board shall maintain a capital account for each Interestholder of the Company and allocate net profits, net losses and other items of Company income, gain, loss and deduction to each Interestholder’s capital account, in each case, for U.S. federal income tax purposes and in accordance with such provisions as ADS prescribes. The Board also shall apply the provisions of the immediately preceding sentence with respect to each subsidiary of the Company that is intended to be classified as a partnership for U.S. federal income tax purposes. The Interestholders are aware of the U.S. federal income tax consequences of the designations of the Company’s and any Subsidiary’s U.S. tax status under this Agreement and hereby agree to be bound by such designations in reporting their shares of Company, or any Subsidiary, income and loss for U.S. federal income tax purposes.

6.2 Tax Matters Generally; Tax Returns. The Company shall prepare and timely file (or cause to be prepared and timely filed) all Tax Returns required to be filed by the Company and/or any Subsidiary. The Company shall deliver a copy of each such material Tax Return to the Interestholders on or before ten (10) Days following the due date of any such Tax Return. The Company shall provide (or cause to be provided) to an Interestholder such information as such Interestholder requests to enable such Interestholder to comply with its (or its Affiliates) tax reporting or filing obligations. The Company shall bear the cost of the preparation and filing of all Tax Returns and the preparation and providing of information to the Interestholders. The Company shall not settle or resolve any material Tax audits relating to the Company or any Subsidiary without prior approval by the Board.

ARTICLE VII

DISPOSITION OF INTERESTS

7.1 General Restrictions. No Interestholder may Dispose of or Encumber all or any portion of its Interests without the advance written consent of the other Interestholder, except as provided in this Article VII. Notwithstanding any provision in this Article VII to the contrary, (a) an Interestholder may not make any Disposition of less than all of its Interests, and such Disposition may only be for Cash and only to a single transferee; (b) no Interestholder shall be permitted to transfer any Interests to a Person on the other Interestholder’s Prohibited List or any Affiliate of such Person; (c) except for Dispositions described in Section 7.1(d), an Interestholder may not make any Disposition to a Person who is engaged, directly or indirectly, in the other Interestholder’s Competing Business; and (d) the Disposition of Interests by an Interestholder to an Affiliate of the Interestholder shall not require the advance written consent of the other Interestholder or compliance with Section 7.2 (but shall comply with the requirements of Section 7.3). Any attempted Disposition or Encumbrance of all or any portion of the Interests, other than in strict accordance with this Article VII, shall be, and is hereby declared, null and void ab initio.

7.2 Right of First Refusal; Tag Along Right.

(a) Transfer Notice. In the event that any Interestholder at any time desires to Dispose of all of its Interests, then such Interestholder (the “Disposing Interestholder”) shall promptly give written notice thereof (the “Transfer Notice”) to the other Interestholder (the “Notified Interestholder”). The Transfer Notice shall set forth the following:

(i) The number of Interests of the Disposing Interestholder which the prospective acquirer will purchase (which number shall necessarily be the total number of the Interests held by the Disposing Interestholder);

(ii) The name of the prospective acquirer, which may not be (A) a Person on the other Interestholder’s Prohibited List or any Affiliate of such Person or (B) a Person who is engaged, directly or indirectly, in the other Interestholder’s Competing Business;

(iii) The price offered by the prospective acquirer for the Interests and the method of payment therefor; and

(iv) Any other applicable terms and conditions of the proposed Disposition.

The Notified Interestholder shall have thirty (30) Days following its receipt of the Transfer Notice (the “Exercise Period”) in which to notify the Disposing Interestholder whether the Notified Interestholder desires to exercise its Right of First Refusal or Tag Along Right (an “Exercise Notice”). The procedures for exercising and implementing an Interestholder’s Right of First Refusal and/or Tag Along Right are set forth in Sections 7.2(b) and 7.2(c), respectively.

- 40 -

If the Notified Interestholder does not respond during the Exercise Period, the Notified Interestholder shall be deemed to have waived its Right of First Refusal and Tag Along Right. If the terms of a proposed Disposition are different than or modified from those set forth in the Transfer Notice related thereto, any waiver by an Interestholder of its Right of First Refusal or Tag Along Right with respect to such proposed Disposition shall be invalid and, notwithstanding any such waiver, the proposed Disposition shall again become subject to the Right of First Refusal and Tag Along Right provisions set forth in this Section 7.2.

(b) Right of First Refusal. Upon receipt of a Transfer Notice, the Notified Interestholder shall have the preferential right to acquire the Disposing Interestholder’s Interests for the same purchase price, and on the same terms and conditions, as are set forth in the Transfer Notice (the “Right of First Refusal”). If the Right of First Refusal is exercised in accordance with this Section 7.2, the closing of such purchase (the “First Refusal Closing”) shall occur at the offices of ▇▇▇▇▇ y Cia. Ltda. in Santiago, Chile, on or before the later of (i) the thirtieth (30th) Day after the expiration of the Exercise Period or (ii) the fifth (5th) Business Day after the receipt of all applicable regulatory and governmental approvals to the purchase, if any. At the First Refusal Closing: (A) the Disposing Interestholder shall execute and deliver to the Notified Interestholder (1) an Assignment of the Interests described in the Transfer Notice, in form and substance reasonably acceptable to the Notified Interestholder and (2) any other instruments reasonably requested by the Notified Interestholder to give effect to the purchase; and (B) the Notified Interestholder shall deliver to the Disposing Interestholder the purchase price specified in the Transfer Notice in immediately available funds. In the event that the Disposing Interestholder refuses to execute such Assignment following the Notified Interestholder’s compliance with the procedures set forth in Section 7.2(a) and (b), the Disposing Interestholder shall be in material breach of this Agreement, and the Notified Interestholder shall be entitled to obtain an order compelling the Disposing Interestholder to execute and deliver such Assignment pursuant to the dispute resolution procedures set forth in Section 10.1.

(c) Tag Along Right. As an alternative to the Right of First Refusal, upon receipt of a Transfer Notice, the Notified Interestholder shall have the right to require, prior to the Disposing Interestholder’s Disposition of its Interests to the prospective acquirer, that the Disposing Interestholder must cause the prospective acquirer to purchase all of the Interests of the Notified Interestholder, at the same price and on the same terms and conditions as the prospective acquirer has offered to purchase the Interests of the Disposing Interestholder (the “Tag Along Right”). If the Notified Interestholder exercises its Tag Along Right, the Disposing Interestholder must cause the prospective acquirer to purchase all of the Interests of both the Disposing Interestholder and the Notified Interestholder or the Disposing Interestholder may not sell its Interests to the prospective acquirer. If the Tag Along Right is exercised in accordance with Section 7.2(a) and the prospective acquirer is willing to purchase the Interests of both the Disposing Interestholder and the Notified Interestholder, the closing of such purchase (the “Tag Along Closing”) shall occur at the offices of ▇▇▇▇▇ y Cia. Ltda. in Santiago, Chile, on a date mutually agreeable to the prospective acquirer, the Disposing Interestholder and the Notified Interestholder. At the Tag Along Closing: (i) each of the Interestholders shall concurrently execute and deliver to the prospective acquirer (A) an Assignment of all of its respective Interests, in form and substance reasonably acceptable to the prospective acquirer, and (B) any other instruments reasonably requested by the prospective acquirer to give effect to the purchase; and (ii) the prospective acquirer shall deliver to each of the Interestholders an amount equal to

- 41 -

the price specified in the Transfer Notice in immediately available funds. In the event that either Interestholder refuses to execute such an Assignment following the other Interestholder’s compliance with the procedures set forth in Section 7.2(a) and (c), the Interestholder refusing to execute such an Assignment shall be in material breach of this Agreement, and the other Interestholder shall be entitled to obtain an order compelling the refusing Interestholder to execute and deliver such an Assignment pursuant to the dispute resolution procedures set forth in Section 10.1.

(d) Sufficiency of Payment. Subject to any unpaid charges under any of the JV Documents and/or any other obligations or liabilities existing among the selling Interestholder, the other Interestholder and the Company as of the First Refusal Closing or Tag Along Closing, as the case may be, the payment to the Disposing Interestholder pursuant to this Section 7.2 will be, and will be deemed to be, in complete liquidation and satisfaction of all the rights and interest of the Disposing Interestholder (and of all Persons claiming by, through, or under the Disposing Interestholder) in and in respect of the Company, including any rights against the Company and (insofar as the affairs of the Company are concerned) against the other Interestholder.

(e) Waiver of Right of First Refusal and Tag Along Right. If the Notified Interestholder (i) does not deliver an Exercise Notice prior to the deadline therefor set forth in Section 7.2(a) or (ii) affirmatively waives its Right of First Refusal and Tag Along Right, then the Disposing Interestholder shall have the right, subject to compliance with the provisions of this Article VII, to Dispose of the Interests described in the Transfer Notice to the proposed acquirer strictly in accordance with the terms of the Transfer Notice for a period of thirty (30) Days after the expiration of the Exercise Period (the “Disposition Period”). If, however, the Disposing Interestholder fails to so Dispose of such Interests within such Disposition Period, the proposed Disposition shall again become subject to the Right of First Refusal and Tag Along Right provisions set forth in this Section 7.2.

7.3 Requirements Applicable to All Dispositions and Admissions. In addition to the requirements set forth in Section 7.1 or 7.2, any Disposition of Interests shall also be subject to the following requirements, and such Disposition (and admission, if applicable) shall not be effective unless such requirements are complied with:

(a) Disposition Documents. The following documents must be delivered to the non-Disposing Interestholder and must be reasonably satisfactory, in form and substance, to the non-Disposing Interestholder:

(i) A copy of the Assignment pursuant to which the Disposition is effected.

(ii) An instrument, executed by the Disposing Interestholder and its transferee, containing the following information and agreements, to the extent they are not contained in the instrument described in Section 7.3(a)(i):

(A) The notice address of the transferee;

- 42 -

(B) The transferee’s ratification of this Agreement and agreement to be bound by it;

(D) Representations and warranties by the Disposing Interestholder and the transferee (1) that the Disposition, is being made in accordance with all applicable Law, and (2) that the instruments provided in response to this Section 7.3(a)(i) and (ii) are true and correct.

(b) Payment of Expenses. The Disposing Interestholder shall promptly pay, or reimburse the Company for, all costs and expenses incurred by the Company in connection with the Disposition, on or before the tenth (10th) Day after receipt of the Company’s invoice for the amount due.

(c) Effective Date. Each Disposition complying with the provisions of this Article VII is effective as of the Day in which all of the requirements of this Section 7.3 have been met.

7.4 Encumbrances. No Interestholder may Encumber all or any portion of its Interests without the consent of the other Interestholder. If the other Interestholder consents to the creation by an Interestholder of an Encumbrance on its Interests, the Interestholder effecting such Encumbrance shall ensure that the applicable secured party executes and delivers to the Interestholders a signed writing by which such secured party (a) acknowledges the rights of the Interestholders under Section 7.3 and Article VIII and (b) agrees to allow the exercise of such rights prior to any foreclosure by such secured party or its assignees on the Interests subject to such Encumbrance.

7.5 Direct Ownership Interests in Subsidiaries.

(a) Restrictions Against Dispositions. No Interestholder may Dispose of any portion of its direct interests in the ownership of any Subsidiary without the advance written consent of the other Interestholder, except in connection with a Disposition of its Interests permitted by and made in accordance with this Article VII. If an Interestholder Disposes of its Interests in a Disposition permitted by and made in accordance with this Article VII, the disposing Interestholder shall also Dispose of all of its direct interests in the ownership of each Subsidiary in a manner that results in the owner of the Disposed Interest also holding all of the direct interests in the ownership of each Subsidiary previously held by the Disposing Interestholder.

(b) Restrictions Against Encumbrances. No Interestholder may Encumber all or any portion of its direct interests in the ownership of any Subsidiary without the consent of the other Interestholder. If the other Interestholder consents to the creation by an Interestholder of an Encumbrance on its direct interests in the ownership of any Subsidiary, the Interestholder effecting such Encumbrance shall ensure that the applicable secured party executes and delivers to the Interestholders a signed writing by which such secured party (a) acknowledges the rights of the Interestholders under Section 7.5(a) and Article VIII and (b) agrees to allow the exercise of such rights prior to any foreclosure by such secured party or its assignees on the direct interests in the ownership of any Subsidiary subject to such Encumbrance.

(c) Attempted Dispositions or Encumbrances in Violation of Agreement. Any attempted Disposition or Encumbrance of all or any portion of the direct interests in the ownership of any Subsidiary held by any Interestholder, other than in strict accordance with this Section 7.5, shall be, and is hereby declared, null and void ab initio.

- 43 -

7.6 Specific Performance. The Interestholders agree that breach of the provisions of this Article VII may cause irreparable injury to the Company, the Interestholders and/or their Affiliates for which monetary damages (or other remedy at law) are inadequate in view of (a) the complexities and uncertainties in measuring the actual damages that would be sustained by reason of the failure of compliance with such provisions, and (b) the uniqueness of the Business and the relationships among the Interestholders and their Affiliates. Accordingly, the Interestholders agree that the provisions of this Article VII may be enforced by specific performance (cumplimiento forzado).

(a) Rights of Non-Affected Interestholder. If a Termination Event of the type described in Section 8.1(d) occurs, as part of the arbitration proceeding in which the finding described in Section 8.1(d) is made, the non-Affected Interestholder shall be entitled to (i) initiate the buy/sell procedure described in Section 8.2(b) or (ii) cause the liquidation of the Company pursuant to the provisions of Article XI.

(ii) Rights of Affected Interestholder. Within thirty (30) Days of the receipt by the Affected Interestholder of the Material Breach Buy/Sell Notice, the Affected Interestholder shall elect, via delivery of notice to the non-Affected Interestholder and such arbitrator, to, in a transaction overseen by the arbitrator of such arbitration proceeding, either (A) sell all, but not less than all, of the Interests of the Affected Interestholder to the non-Affected Interestholder or its designee for cash in an amount equal to ninety percent (90%) of the price designated in the Material Breach Buy/Sell Notice minus the amount of damages resulting from the Affected Interestholder’s breach of the Agreement that is the basis for the Termination Event (as determined by such arbitrator) (the “Material Breach Arbitration Award”) or (B) purchase all, but not less than all, of the Interests of the non-Affected Interestholder for cash in an amount equal to one hundred percent (100%) of the price designated in the Material Breach Buy/Sell Notice plus the Material Breach Arbitration Award.

(iv) Sufficiency of Payment. Subject to any unpaid charges under any of the JV Documents and/or any other obligations or liabilities existing among the selling Interestholder, the other Interestholder and the Company as of the closing of the transactions described in Section 8.2(b), the payment to the selling Interestholder pursuant to this Section 8.2 will be, and will be deemed to be, in complete liquidation and satisfaction of all the rights and interest of the selling Interestholder (and of all Persons claiming by, through, or under the selling Interestholder) in and in respect of the Company, including any rights against the Company and (insofar as the affairs of the Company are concerned) against the other Interestholder.

(b) Exercise of Termination Rights. The non-Affected Interestholder may exercise such rights by notifying the Affected Interestholder (or its representative) of the exercise of such option within thirty (30) Days following the later of the occurrence of such Termination Event and the receipt by the non-Affected Interestholder of the Affected Interestholder’s notice as required by the first sentence of Section 8.4(a), (the “Termination Option Period”).

- 46 -

(c) Effectuation of Termination Option. If, during the Termination Option Period, the non-Affected Interestholder (the “Termination Buyer”) exercises its option under Section 8.4 to acquire all of the Interests held by the Affected Interestholder, then each of the following shall apply:

(ii) Termination Option Closing Date and Location. The date for the sale transaction described in Section 8.4 shall be selected by the Termination Buyer but shall occur on or before the later of (A) if no Formal Termination Valuation is utilized, forty-five (45) Days, or if a Formal Termination Valuation is utilized, ninety (90) Days, after the end of the Termination Option Period or (B) the fifth (5th) Business Day after the receipt of all applicable regulatory and governmental approvals to such sale transaction, if any. The closing of such sale transaction shall occur at the offices of ▇▇▇▇▇ y Cia. Ltda. in Santiago, Chile.

(iii) Sufficiency of Payment. Subject to any unpaid charges under any of the JV Documents and/or any other obligations or liabilities existing among the selling Interestholder, the other Interestholder and the Company as of the closing of the sale transaction described in Section 8.4, the payment to the Affected Interestholder pursuant to this Section 8.4 will be, and will be deemed to be, in complete liquidation and satisfaction of all the rights and interest of the Affected Interestholder (and of all Persons claiming by, through, or under the Affected Interestholder) in and in respect of the Company, including any rights against the Company and (insofar as the affairs of the Company are concerned) against the other Interestholder.

(iv) Determination of Fair Market Value. The fair market value of the Interests of the Affected Interestholder to be sold pursuant to this Section 8.4 shall be determined, if possible, by the mutual agreement of the Termination Buyer and the Affected Interestholder. If the Termination Buyer and the Affected Interestholder do not reach such agreement as to fair market value of such Interests on or before the thirtieth (30th) Day following the end of the Termination Option Period, either of them, by notice to the other, may require the determination of fair market value to be made by the Valuation Specialist (such determination by the Valuation Specialist, the “Formal Termination Valuation”).

ARTICLE XV

GENERAL PROVISIONS

15.1 Notices. All notices, requests or consents provided for or permitted to be given under this Agreement must be in writing in the English language and must be delivered to the recipient in person or by internationally recognized overnight courier (except that notices of Board meetings may be sent to Board members via electronic mail transmission to the electronic mail addresses of the members of the Board on record with the Company); and any notice,

- 70 -

request or consent given under this Agreement shall be effective upon receipt. All notices, requests and consents to be sent to an Interestholder must be sent to or made at the addresses given for that Interestholder on Schedule I, or such other address as that Interestholder may specify by notice to the other Interestholder pursuant to this Section 15.1. Any notice, request or consent to the Company must be given to all of the Interestholders. Whenever any notice is required to be given by Law or this Agreement, a written waiver thereof, signed by the Person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice.

15.2 Entire Agreement. This Agreement, including the Exhibits, Schedules and Disclosure Schedules attached hereto, constitutes the entire agreement relating to the formation and organization of the Company and supersedes all prior contracts or agreements with respect to such matters, whether oral or written. The Confidentiality Agreement is hereby superseded in its entirety by this Agreement. Upon their execution and delivery, each of the JV Documents will be an integral part of the joint venture relationship between the Interestholders contemplated by this Agreement.

15.3 Effect of Waiver or Consent. A waiver or consent, express or implied, to or of any breach or default by any Person in the performance by that Person of its obligations with respect to the Company or this Agreement is not a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person with respect to the Company or this Agreement. Failure on the part of a Person to complain of any act of any Person or to declare any Person in default with respect to the Company or this Agreement, irrespective of how long that failure continues, does not constitute a waiver by that Person of its rights with respect to that default until the applicable statute of limitations period has run.

15.4 Amendments. This Agreement may be amended only by a written instrument executed by all of the Interestholders.

15.5 Binding Effect; No Third-Party Beneficiaries; Remedies Not Exclusive. This Agreement is binding on and inures to the benefit of each Interestholder and its respective heirs, legal representatives, successors, and assigns. This Agreement is solely for the benefit of the Interestholders, their Affiliates, the Indemnitees and their respective successors and permitted assigns, and this Agreement shall not otherwise be deemed to confer upon or give to any other third party any remedy, claim, liability, reimbursement, cause of action or other right. Except as otherwise expressly stated in this Agreement, the rights and remedies provided by this Agreement are cumulative and the use of any one right or remedy shall not preclude or constitute a waiver of a right to use any or all other remedies. Such rights and remedies are given in addition to any other rights and remedies a party may have by Law or otherwise.

15.6 Governing Law; Severability. This Agreement (including any matters relating to Article X and/or any substantive or procedural issues relating to any arbitration pursuant thereto that are not governed by the ICC Rules) is governed by and shall be construed in accordance with Chilean Law, excluding any conflict of laws rule or principle that might refer the governance or the construction of this Agreement to the law of another jurisdiction. Nothing in this Agreement shall preclude bringing enforcement proceedings in any jurisdiction in order to

- 71 -

enforce any judgment obtained in any other proceeding or to compel arbitration or enforce an order or judgment of the arbitrator, nor shall the bringing of such enforcement proceedings in any one or more jurisdictions preclude the bringing of enforcement proceedings in any other jurisdiction. If any noncompetition restriction on the activities of the Company and its Subsidiaries set forth in Article IX of this Agreement is determined to be invalid, illegal or unenforceable, such restriction shall remain in full force and effect to the extent determined to be valid, legal and enforceable. Further, no Party shall be entitled to exercise its rights under Section 3.7 or Section 11.1(d) with respect to a modification to any such restriction unless such modification would affect the restriction throughout the entire Territory.

15.7 Further Assurances. In connection with this Agreement and the transactions contemplated hereby, each Interestholder (and their permitted successors or assigns) shall execute and deliver any additional documents and instruments and perform any additional acts that may be reasonably necessary or appropriate to effectuate and perform the provisions of this Agreement and those transactions.

15.8 Language. This Agreement has been drafted and executed in English. In the event this Agreement is translated into any other language, such translation shall be for informational purposes and the English version shall prevail over any other version. The Interestholders hereby undertake to amend the Bylaws of the Company each time it may be necessary to conform them to the provisions of this Agreement. Accordingly, if in the future there shall exist any discrepancy between this Agreement and the Bylaws of the Company, this Agreement shall prevail and the Interestholders shall amend the Bylaws to the extent necessary to eliminate such discrepancy.

15.9 Directly or Indirectly; Without Limitation. Where any provision in this Agreement refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person, including actions taken by or on behalf of any Affiliate of such Person. Where any provision of this Agreement refers to action to be taken by the Interestholders, unless the language or context indicates otherwise, such action shall be deemed to require the action of all of the Interestholders. Throughout this Agreement, the term “including” and words to the same or similar effect shall be interpreted and construed to mean “including without limitation.”

15.10 Fees and Expenses. Except as set forth in Section 14.6, each of the Parties will bear its own costs and expenses (including without limitation the fees and expenses of any advisor, accountant, attorney or other representative retained by it, including any brokerage, commission, finder’s or financial advisory fees) incurred in connection with this Agreement and the transactions contemplated hereby.

15.11 References. All references herein to one gender shall include the others and the singular shall include the plural and vice versa as appropriate. All references to an entity shall be deemed to include its successors and assigns, to the extent succession or assignment is not restricted by this Agreement. Unless otherwise expressly provided, all references to “Articles” or “Sections” are to Articles or Sections of this Agreement.

15.12 Counterparts. This Agreement may be executed in one or more counterparts (including by means of facsimile), each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

15.13 Headings. The Article and Section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement.

5. Meaning of “Agreement”.

6. Ratification and Confirmation of the Interestholders Agreement. Tigre and ADS do hereby ratify and reaffirm all of the terms and provisions of the Interestholders Agreement, which, as amended and supplemented by this Amendment, shall remain in full force and effect.
