(b) The Parties agree that, from and after the Closing Date to and including the date on which such claim or cause of action against any of the Parties is based upon, directly or indirectly, a breach of any of the representations, warranties, covenants or agreements contained in this Agreement may be brought only, as expressly provided in, this Article VIII, and the indemnification provided for in this Article VIII shall be the sole and exclusive remedy (except in the case of fraud) for Losses related to or in connection with such breach.

8.2 Indemnification of Purchaser by Seller. Subject to the terms and conditions of this Article VIII, and except when the Loss arises from Purchaser’s negligence or willful misconduct or the matters contemplated by Section 8.5, from and after the Closing Date the Seller shall, subject to Section 8.4, indemnify, defend and hold Purchaser and each of Purchaser’s Affiliates, directors, officers and employees and the successors and assigns of any of them (including, without limitation, the Company) (collectively, the “Purchaser Group”) harmless from and against all Losses, arising from any claim resulting from, imposed upon or incurred by any member of the Purchaser Group, directly or indirectly, by reason of or resulting from any misrepresentation or inaccuracy of any representation or warranty of the Seller contained in or made pursuant to Articles II or III of this Agreement and/or any breach by Seller of any of its covenants, agreements or obligations contained in or made pursuant to this Agreement. Payments to Purchaser under this Section 8.2 shall be made in reais, calculated at the exchange rate on the date or dates Seller makes payment or payments to Purchaser.

8.3 Indemnification of Seller by Purchaser. Subject to the terms and conditions of this Article VIII, and except when the Loss arises from Seller’s negligence or willful misconduct, from and after the Closing Date Purchaser shall indemnify, defend and hold Seller, its Affiliates and each of their respective officers, directors, employees, agents and representatives (the “Seller Group”) harmless from and against all Losses arising from any claim resulting from, imposed upon or incurred by Seller, directly or indirectly, by reason of or resulting from any misrepresentation or inaccuracy of any representation or warranty of Purchaser contained in or made pursuant to Article IV of this Agreement; and/or any breach by Purchaser of any of its covenants, agreements or obligations of Purchaser contained in or made pursuant to this Agreement (including, without limitation, the matters contemplated by the proviso of the last sentence of Section 5.7). Payments to Seller under this Section 8.3 shall be made in U.S. currency, calculated at the exchange rate on the date or dates Purchaser makes payment or payments to Seller or any other member of the Seller Group.

8.4 Limitations on Seller’s Indemnification.

(a) Limitations. Claims for indemnification under Section 8.2 shall be made by Purchaser or by any other Person of the Purchaser Group in accordance with the following limits:

(i) if such claim involves Losses equal to or in excess of US$50,000 (the “Mini-Basket Amount”); and

(ii) if such Losses with respect to the claims permitted to be made pursuant to the foregoing clause (i) exceed in the aggregate an amount equal to US$500,000 (the “Deductible Amount”), and then only to the extent such Losses exceed the Deductible Amount.

(b) Losses Below the Deductible Amount. Notwithstanding the provisions of this Section 8.4, if claims made prior to the Survival Period Termination Date do not reach the Deductible Amount, Seller agrees to pay to Purchaser the aggregate amount of the Losses related to such claims meeting the Mini-Basket Amount definition and made until the Survival Period Termination Date.

(c) Indemnification Cap. The aggregate amount of Losses payable by Seller under this Agreement shall not exceed US$10,000,000 (the “Indemnification Cap”) in the aggregate.

(d) Calculation of Losses. The amount of any Loss subject to indemnification under Section 8.2 or 8.3 shall be calculated net of any insurance proceeds (net of direct collection expenses, deductibles and co-pays) or any indemnity, contribution or other similar payment received by Indemnitee from any third party with respect thereto. To the extent a Loss is reasonably expected to be covered by such policies, Indemnitee shall use commercially reasonable efforts to recover under its insurance policies covering such Loss to the same extent as they would if such Loss were not subject to indemnification hereunder; provided, however, that nothing in this Section 8.4(d) shall prevent Indemnitee from also seeking to recover such Loss from Indemnitor while such insurance claim is pending. In the event that an insurance or other recovery is made by Indemnitee with respect to any Loss for which any such Person has been indemnified hereunder, then a refund equal to the aggregate amount of the recovery (not to exceed the amount of the applicable indemnification payment made to it) shall be made promptly to Seller. Indemnitor shall be subrogated to all rights of Indemnitee and its Affiliates in respect of any Losses indemnified by Indemnitor.

8.5 Special Indemnification by Seller.

(a) General. Notwithstanding any provision to the contrary in this Agreement or any other agreement contemplated hereby, from and after the Closing Date, Seller shall indemnify Purchaser against and hold it harmless from any Losses that result from or arise out of the matters set forth on Schedule 8.5(a), which shall be excluded from the Seller’s indemnification obligations and limits under Sections 8.2, 8.4(a), 8.4(b) and 8.4(c).

(b) Special Seller Indemnification Cap. In no event shall the aggregate amount of Losses payable by Seller under Section 8.5 exceed US$8,800,000 (the “Special Seller Indemnification Cap”) in the aggregate.

(c) Expiration. With respect to the claim noted in item 4 of Schedule 8.5(a), the Seller’s obligations under this Section 8.5(c) shall expire on October 27, 2009, unless a Third Party Claim (as defined in Section 8.7(a)) based on a Promissory Note is made with respect thereto prior to such date; provided that, if the enforceability of such a Promissory Note is tolled prior to the making of such Third Party Claim, the expiration date of Seller’s obligation with respect to such Promissory Note under this Section 8.5(c) shall be extended for a number of days equal to the number of days during which such enforceability was tolled. With respect to the other matters noted in Schedule 8.5(a), Seller’s obligations under this Section 8.5(c) shall expire on the fifteenth anniversary of the Closing Date.

(d) Payments. Payments to Purchaser under this Section 8.5 shall be made in reais, calculated at the exchange rate on the date or dates Seller makes payment or payments to Purchaser.

8.6 Mitigation. Each Person entitled to indemnification hereunder shall take commercially reasonable steps to mitigate all Losses after becoming aware of any event that could reasonably be expected to give rise to any Loss that is subject to indemnification hereunder.

8.7 General Procedures Applicable to Claims for Indemnification.

(a) Third Party Claim. Any request for indemnification by a party under this Article VIII shall be valid only if the party making the request (“Indemnitee”) notifies the other party in writing (“Indemnitor”) as promptly as reasonably practicable by written notice in accordance with Section 10.1 regarding a claim or demand made by any Person (other than a Party or Affiliate thereof) (“Third Party Claim”). Notice shall specify the nature of the Third Party Claim, the applicable provision(s) of this Agreement under which the Third Party Claim arises and, if possible, the amount of, or an estimated amount of, the Loss and such other information as Indemnitor may reasonably request. No failure or delay in giving a Third Party Claim Notice and no failure to include any specific information or any reference to any provision of this Agreement or other instrument under which the Third Party Claim arises shall affect the rights of Indemnitee hereunder, except to the extent that such failure or delay materially adversely affects the ability of Indemnitor to defend, settle or satisfy the Third Party Claim.

(b) Right of Indemnitor to Assume Defense of Claim; Control of the Defense. Indemnitor, at its sole cost and expense, shall have the right, upon written notice to Indemnitee to assume the defense of the Third Party Claim if in such written notice Indemnitor acknowledges in writing that the Third Party Claim is covered by the indemnification obligations under this Article VIII and all Losses incurred by Indemnitor shall be included in the calculation of the maximum amount of indemnification set forth in Section 8.4(c). If Indemnitor assumes the defense of the Third Party Claim, it shall select reputable counsel reasonably acceptable to Indemnitee to conduct the defense of the Third Party Claim and shall defend or settle the same. The contest of the Third Party Claim may be conducted in the name and on behalf of Indemnitor or Indemnitee, as the case may be appropriate. If Indemnitor assumes the defense of such claim, Indemnitor shall have full authority, in consultation with Indemnitee, to determine all action to be taken with respect to the Third Party Claim, except that Indemnitor may consent to a settlement or compromise of, or the entry of any monetary judgment arising from, the Third Party Claim only with the prior written consent of Indemnitee provided that, the proposed settlement, compromise or entry: (A) does not contain an admission of guilt or wrongdoing on the part of Indemnitee, and (B) does not provide for any remedy or sanction against Indemnitee other than the payment of money that is required to be and is timely paid by Indemnitor. Should Indemnitor so elect to assume the defense of such Third Party Claim, Indemnitor will not be liable to Indemnitee for legal expenses subsequently incurred by Indemnitee in connection with the defense thereof, unless the Third Party Claim involves potential conflicts of interest between Indemnitee and Indemnitor. Indemnitor will be liable for the fees and expenses of counsel employed by Indemnitee for any period during which Indemnitor has not assumed the defense thereof.

(c) Cooperation in Defense. If requested by Indemnitor, Indemnitee shall cooperate with Indemnitor and its counsel, including permitting reasonable access to books and records, in contesting any Third Party Claim that Indemnitor elects to contest or, if appropriate, in making any counterclaim against the Person asserting the Third Party Claim or any cross-complaint against any Person, but Indemnitor shall reimburse Indemnitee for reasonable out-of-pocket costs incurred by Indemnitee in so cooperating. With respect to any claims arising out or relating to Section 8.5, Purchaser shall, and shall cause its Affiliates to, provide Seller with such assistance as may reasonably be requested by Seller in connection with any indemnification or defense with respect to the matters provided for in Section 8.5, including, without limitation, providing Seller with such information, documents and records and reasonable access to the services of and consultations with such personnel of Purchaser or its Affiliates as Seller shall deem reasonably necessary.

(d) Failure of Indemnitor to Assume Defense. If Indemnitor does not inform Indemnitee in writing that it will assume the defense of the Third Party Claim in accordance with the terms hereof within one third of the legal term for defense or five (5) calendar days, whichever is less, after the receipt of notice thereof, Indemnitee may, but not in any means shall be obliged to, at Indemnitor’s sole expense, defend against the Third Party Claim in such manner as it may deem appropriate, and the expense of such defense shall constitute an indemnifiable Loss, which amounts shall be included in the calculation of the maximum amount of indemnification set forth in Section 8.4(c). Indemnitor shall have the right, and Indemnitee shall use its reasonable efforts to afford Indemnitor, to have its counsel attend, observe and participate in all administrative and judicial meetings, conferences, hearings and other proceedings in connection with such defense and to be provided with copies of, or reasonable access to, all pleadings, notices and other filings in connection with such defense.

(e) Dispute Resolution. In the event that Indemnitee should have a claim against Indemnitor under this Article VIII, Indemnitee shall notify Indemnitor in writing, and in reasonable detail, of such claim as promptly as reasonably practicable, including (i) the reason why Indemnitee believes that Indemnitor is or will be obligated to indemnify Indemnitee, (ii) the Loss amount and (iii) the basis on which Indemnitee has calculated such Loss amount (such notice shall be referred to as the “Notice of Claim”). If, within twenty (20) Business Days upon receipt of the Notice of Claim, Indemnitor does not deliver a notice in writing disputing in good faith such Notice of Claim, then Indemnitor shall be deemed to have accepted such claim and the Loss amount as final and binding without amendment or modification and conclusive upon the parties. For ten (10) Business Days after the receipt of the Notice of Claim, Indemnitor and Indemnitee shall use reasonable efforts to engage in negotiations and discussions relating to any matters arising out of or concerning the Notice of Claim. If Indemnitor and Indemnitee shall fail to resolve any such dispute during the 10-Business Day period, then the claim in dispute shall be promptly submitted by Indemnitor (in any event, no later than five (5) Business Days after the 10-Business Day period) to the Panel in accordance with Section 10.9 of this Agreement. Indemnitor and Indemnitee shall make readily available to the Panel all relevant books and records, notices and documents, and all other items reasonably requested by the Panel. Section 10.9 shall govern the resolution of disagreements among the Parties under this Article VIII.

8.8 Payment. Indemnitor shall reimburse Indemnitee for Losses incurred no later than ten (10) days after the final resolution of a Notice of Claim in accordance with Section 8.7(e) or, with respect to Losses in relation to Third Party Claims (other than on-going out-of-pocket costs and expenses with respect thereto), ten (10) days after Indemnitor receives written notice from Indemnitee reasonably describing the Loss being claimed (“Loss Payment Date”). Failure to comply with the Loss Payment Date shall cause the Loss amount to be duly adjusted by IGP-M, plus interest of one percent (1%) per month with respect to Losses paid in reais.

8.9 Energy Guarantee.

(a) For value received, Energy hereby fully, unconditionally and irrevocably guarantees from and after the Closing Date (the “Energy Guarantee”) to Purchaser the prompt and punctual payment of any amount Seller is required to pay under this Agreement, when and as the same shall become due and payable, subject as to such payment obligations to the terms and conditions of this Article VIII. Energy’s guarantee obligations include the principal, interest, fines, fees, costs and other amounts that may be due and payable by Seller under this Agreement.

(b) The Energy Guarantee is a first demand guarantee and shall constitute an autonomous and independent obligation of Energy not being ancillary to the obligations of Seller under this Agreement. Energy hereby agrees to cause any such payment to be made as if such payment were made by Seller. Energy hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of a merger or bankruptcy of Seller, any right to require a proceeding first against Seller, protest or notice with respect to any amount payable by Seller under this Agreement and all demands whatsoever, and covenants that the Energy Guarantee will not be discharged except by (i) termination of this Agreement according to its terms, (ii) termination or expiration of Seller’s indemnification obligations under this Agreement or (iii) payment in full of all amounts due and payable under this Agreement.

(c) Energy expressly waives the benefits set forth in Articles 366, 827, 835, 837, 838 and 839 of the Brazilian Civil Code and Article 595 of the Brazilian Code of Civil Procedure.

(d) The applicability of the Energy Guarantee shall not be affected or impaired by any of the following: (i) any extension of time, forbearance or concession given to Seller; (ii) any assertion of, or failure to assert, or delay in asserting, any right, power or remedy against Seller; (iii) any amendment of the provisions of this Agreement; (iv) any failure of Seller to comply with any requirement of any Law; (v) the dissolution, liquidation, reorganization or any other alteration of the legal structure of Seller; (vi) any invalidity or unenforceability of any provision of this Agreement; or (vii) any other circumstance (other than complete payment by Seller or Energy) which might otherwise constitute a legal or equitable discharge or defense of a surety or a guarantor.

(e) Energy shall be subrogated to all rights of Seller against Purchaser based on and to the extent of any amounts paid to Purchaser by Energy pursuant to the provisions of the Energy Guarantee.

(f) All notices under this Article VIII from Purchaser or any member of the Purchaser Group shall be given to Seller and Energy concurrently.

All notices under this Agreement for Purchaser or any member of the Purchaser Group shall be given to Seller and to Energy concurrently. For the purposes of this Section 10.1, notice to the Company shall not constitute notice to Seller and/or Energy, and vice versa.

10.2 Binding Effect. This Agreement shall be binding upon and inure to the benefit of the Parties, Energy and their respective heirs, successors and permitted assigns.

10.3 Assignment; Successors; Third-Party Beneficiaries.

(a) This Agreement is not assignable by any Party or Energy without the prior written consent of all of the other Parties and Energy, as the case may be, and any attempt to assign this Agreement without such consent shall be void and of no effect; provided, however, that Purchaser may assign its rights and obligations hereunder to one or more of its Affiliates (upon prior written notice to Seller), provided that Purchaser remains irrevocably and unconditionally liable for all such rights and obligations; provided, however, that no such assignment shall be permitted if such assignment shall impair, delay or otherwise adversely affect the consummation of the Transaction and the other transactions contemplated hereby.

(b) This Agreement shall inure to the benefit of, and be binding on and enforceable by and against, the successors and permitted assigns of the respective Parties and Energy, whether or not so expressed.

(c) This Agreement is intended for the benefit of the Parties and Energy and does not grant any rights to any third parties.

10.4 Amendment; Waivers; etc. No amendment, modification or discharge of this Agreement, and no waiver under this Agreement, shall be valid or binding unless set forth in writing and duly executed by the Parties and Energy, as the case may be, against whom enforcement of the amendment, modification, discharge or waiver is sought. Any such waiver shall constitute a waiver only with respect to the specific matter described in such writing and shall in no way impair the rights of any of the Parties or Energy, as the case may be, granting such waiver in any other respect or at any other time. The waiver by any of the Parties or Energy, as the case may be, of a breach of or a default under any of the provisions of this Agreement, or any failure or delay to exercise any right or privilege under this Agreement, shall not be construed as a waiver thereof or otherwise affect any of such provisions, rights or privileges under this Agreement. The Parties and Energy shall amend this Agreement to make a wholly owned direct subsidiary of Purchaser a party hereto, provided that Purchaser agrees to cause any such Affiliate to enter into an amendment to this Agreement in accordance herewith pursuant to which Purchaser and such Affiliate shall provide that each of the respective representations, warranties, covenants and agreements made in this Agreement by Purchaser shall constitute the joint and several representations, warranties, covenants and agreements of each of Purchaser and such Affiliate; provided, further, that no amendment shall be permitted if such amendment shall impair, delay or otherwise adversely affect the consummation of the Transaction and the other transactions contemplated hereby and, in any event, after the tenth Business Day following the date hereof.

10.5 Entire Agreement.

(a) This Agreement (including the Exhibits and the Seller Disclosure Letter, Company Disclosure Letter and Purchaser Disclosure Letter referred to in or delivered under this Agreement) and the Confidentiality Agreement contains the entire agreement between the parties relating to the subject matter of this Agreement to the exclusion of any terms implied by Law which may be excluded by contract and supersedes all prior agreements and understandings, both written and oral, among the Parties and Energy with respect to such subject matters. Each of Party and Energy acknowledges that it has not been induced to enter this Agreement by and, in agreeing to enter into this Agreement, it has not relied on, any representations and warranties except as expressly stated or referred to in this Agreement.

(b) The liability of any Party or Energy shall be limited or excluded as set out in this Agreement if and to the extent such limitations or exclusions apply, except for fraud.

10.6 Severability. Any term or provision of this Agreement that is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction or other authority declares that any term or provision hereof is invalid, void or unenforceable, each of the Parties and Energy agree that the court making such determination, to the greatest extent legally permissible, shall have the power to reduce the scope, duration, area or applicability of the term or provision, to delete specific words or phrases, or to replace any invalid, void or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision.

10.7 Counterparts. This Agreement may be executed and delivered (including via facsimile) in several counterparts, each of which shall be deemed an original and all of which shall together constitute one and the same instrument.

10.8 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of Brazil.

10.9 Arbitration. Any dispute, action, claim or controversy of any kind related to, arising from or in connection with this Agreement or the relationship of the parties under this Agreement (the “Dispute”) whether based on contract, tort, common law, equity, statute, regulation, order or any other source of law, shall be finally settled before the International Chamber of Commerce (“ICC”) under the Rules of Arbitration (the “Rules”) of the ICC by three (3) arbitrators designated by the Parties (the “Panel”). Seller (or Energy, to the extent applicable for the limited purposes relating to Section 8.9), on the one hand, and Purchaser, on the other hand, shall each designate one arbitrator to serve on the Panel. The third arbitrator shall be designated by the two arbitrators designated by such parties. If either party fails to designate an arbitrator within thirty (30) days after the filing of the Dispute with the ICC, such arbitrator shall be appointed in the manner prescribed by the Rules. An arbitration proceeding hereunder shall be conducted in New York, New York, and shall be conducted in the English language. The decision or award of the Panel shall be in writing and shall be final and binding on each of the Parties and Energy. The Panel shall award the prevailing party all fees and expenses incurred in connection with the arbitration, including, without limitation, attorneys’ fees and costs, arbitration administrative fees charged by the ICC, Panel member fees and costs, and any other costs associated with the arbitration (the “Arbitration Expenses”); provided, however, that if the claims or defenses are granted in part and rejected in part, the Panel shall proportionately allocate between Seller (or Energy, to the extent applicable for the limited purposes relating to Section 8.9), on the one hand, and Purchaser, on the other hand, the Arbitration Expenses in accordance with the outcomes. The Panel may only award damages as provided for under the terms of this Agreement and in no event may punitive, consequential and/or special damages be awarded. In the event of any conflict between the Rules and any provision hereof, this Agreement shall govern.

10.10 Limitation on Damages. ▇▇▇ of the Parties nor Energy, shall, under any circumstance, have any liability to any of the other parties, for any special, indirect, consequential or punitive damages claimed by any such other party, under the terms of or due to any breach or non-performance of this Agreement, including lost profits, loss of revenue or income, cost of capital, or loss of business reputation or opportunity.

10.11 Enforcement. Each of the Parties and Energy agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not to be performed in accordance with the terms hereof and that Seller shall be entitled to specific performance of the terms hereof in addition to any other remedies at law or in equity.

10.12 No Right of Set-Off. Purchaser, for itself and its successors and permitted assigns, hereby unconditionally and irrevocably waives any rights of set-off, netting, offset, recoupment, or similar rights that such Purchaser or any of its successors and permitted assigns has or may have with respect to the payment of the Purchase Price or any other payments to be made by Purchaser pursuant to this Agreement or any other document or instrument delivered by Purchaser in connection herewith.
