AGREEMENT:

NOW, THEREFORE, in consideration of the foregoing and of the mutual promises, covenants and agreements set forth herein, the parties hereto hereby agree as follows:

ARTICLE I

SALE AND PURCHASE OF SECURITIES

1.1 Sale and Purchase of Securities. At the Closing, Sellers will sell, assign and transfer, and Buyer will purchase and acquire, the full legal and beneficial title, free from any Lien, to all of the Securities.

1.2 Purchase Price. In consideration for the Securities, Buyer shall pay (or cause to be paid) to Sellers an amount equal to the sum of items (a), (b), (c) and (d) below (the “Purchase Price”), with withholding Tax calculated in accordance with items (e) and (f) below, and documented through item (g) below:

(a) an amount in cash equal to $38,113,534.95 (the “Deposit”) will be paid to Sellers, allocated on the basis of $266,000.00 for Galena Shares and $37,847,534.95 for CBL Quotas, concurrently with the execution of this Agreement by wire transfer of immediately available funds to the account of Sellers designated on Exhibit C. On or prior to the Closing Date, but in no event earlier than five (5) Business Days prior to the expected Closing Date, Buyer may in its sole discretion

1

transfer to Sellers $38,113,534.95 together with the Closing Cash Consideration in accordance with Section 1.2(b) to the account of Sellers designated on Exhibit C. On the date of receipt of $38,113,534.95 or as soon thereafter as reasonably possible, Seller shall transfer to Buyer to an account of Buyer, which shall be indicated in writing by Buyer at least five (5) Business Days prior to the expected Closing Date, $38,113,534.95 plus $144,831.43, so that Buyer may re-enter the Deposit in Brazil. If this Agreement is terminated pursuant to Section 8.1 hereof, then the provisions of Section 8.2 will apply with respect to the Deposit;

(b) an amount in cash equal to the Dollar Equivalent of the Closing Cash Consideration will be paid to Sellers on the Closing Date by wire transfer of immediately available funds to an account designated in writing by Sellers at least five (5) Business Days prior to the expected Closing Date;

(c) an amount in cash equal to the Dollar Equivalent of the Preliminary Working Capital Payment will be paid to Sellers on the Closing Date by wire transfer of immediately available funds to an account designated in writing by Sellers at least five (5) Business Days prior to the expected Closing Date;

(d) an amount in cash equal to the Dollar Equivalent of the Working Capital Excess, Financial Debt Excess or Working Capital Shortfall, if any, allocated for Galena Shares and for CBL Quotas will be ascertained and paid in accordance with Sections 1.3.5, 1.3.6 and 1.3.7 on the Working Capital True-Up Date by wire transfer of immediately available funds to an account designated in writing in the case of a Working Capital Excess, by Sellers, and in the case of a Working Capital Shortfall or Financial Debt Excess, by Buyer, at least five (5) Business Days prior to the Working Capital True-Up Date;

(e) an amount in cash equal to the Withholding Tax at Closing Date shall be withheld by Buyer from amounts due to Sellers on the Closing Date and payment in full of such amount shall be made by Buyer to the applicable taxing authorities on the Closing Date;

(f) an amount in cash equal to the Withholding Tax at Working Capital True-Up Date which is withheld by Buyer from the Working Capital Excess pursuant to Section 1.3.6, if any, shall be paid by Buyer to the applicable taxing authorities on the Working Capital True-Up Date; and

(g) As soon as they are available, Buyer shall provide Sellers with certified copies of the Documentos de Arrecadação de Receitas Federais (“DARFs”) evidencing the withholding and payment in full of the Withholding Tax at Closing Date and the Withholding Tax at Working Capital True-Up Date.

1.3 Working Capital and Financial Debt Adjustment.

1.3.1 Promptly after Closing, Buyer will prepare the Closing Working Capital Statement and the Closing Financial Debt Statement in good faith in accordance with the Inventory Valuation Methodologies and the Accounting Methodologies applicable to the calculation of Working Capital and Financial Debt. Buyer agrees to use commercially reasonable efforts given the circumstances to cause the Closing Working Capital Statement and the Closing Financial Debt Statement to be prepared and delivered to Sellers as soon as practicable following the Closing Date, and in any event within sixty (60) days after the Closing Date. The date of delivery of the Closing Working Capital Statement and the Closing Financial Debt Statement to Sellers is referred to herein as the “Delivery Date.”

1.3.2 Sellers will have forty-five (45) days after the Delivery Date (the “Dispute Period”) to dispute that any of the elements of or amounts reflected on the Closing Working Capital Statement and the Closing Financial Debt Statement are not prepared in accordance with the terms of this Agreement (a “Dispute”). Except as to any item on the Closing Working Capital Statement or the Closing Financial Debt Statement as to which Sellers give to Buyer written notice of a Dispute within the Dispute Period (a “Dispute Notice”), the Closing Working Capital Statement and the Closing Financial Debt Statement will be deemed to have been accepted and agreed to by Sellers in all respects as delivered to Sellers. Any Dispute Notice given by Sellers must set forth in reasonable detail the elements and amounts with which Sellers disagree. Within forty-five (45) days after delivery of any Dispute Notice, the parties will attempt to resolve such Dispute and agree in writing upon the final content of the disputed Closing Working Capital Statement and the Closing Financial Debt Statement.

1.3.3 During the Dispute Period and so long as there is any unresolved Dispute outstanding, Buyer and the Companies will (a) permit Sellers and their representatives, at no charge and during normal business hours, to have access to the

2

facilities, personnel and accounting and other records of the Companies to enable Sellers to examine information used in the preparation of the Closing Working Capital Statement and the Closing Financial Debt Statement as provided herein and (b) reasonably cooperate with Sellers and their representatives in respect of their review of the Closing Working Capital Statement and the Closing Financial Debt Statement.

1.3.4 If Buyer and Sellers are unable to resolve any Dispute within the forty-five (45) day period after Buyer’s receipt of a Dispute Notice, Sellers and Buyer will promptly jointly engage Ernst & Young, or such other accounting firm as is mutually agreed by the parties (the “Arbitrating Accountant”) as arbitrator. In connection with the resolution of any Dispute, the Arbitrating Accountant will have confidential access to all documents, records, work papers, facilities and personnel necessary to perform its function as arbitrator. The Arbitrating Accountant’s function and obligation will be to determine the matters in Dispute only in accordance with the requirements of this Section 1.3. The Arbitrating Accountant will allow Buyer and Sellers to present their respective positions regarding the Dispute and will thereafter as promptly as possible provide the parties hereto a written determination of the Dispute, and such written determination will be final and binding upon the parties hereto, subject to Section 10.6. The Arbitrating Accountant will promptly, and in any event within forty-five (45) days after the date of its appointment, render its decision on the question in writing and determine the Dispute. The Arbitrating Accountant may, at its discretion, conduct a conference concerning the Dispute, at which conference each party will have the right to present additional documents, materials and other information and to have present its advisors, counsel and accountants. In connection with such process, there will be no other hearings or any oral examinations, testimony, depositions, discovery or other similar proceedings. The Arbitrating Accountant’s fees and expenses will be paid 50% by Sellers and 50% by Buyer.

1.3.5 If Sellers have failed to deliver a Dispute Notice within the Dispute Period or Sellers have delivered to Buyer written notice that they do not dispute the Closing Working Capital Statement or the Closing Financial Debt Statement (an “Acceptance Notice”), (a) Sellers will be deemed to have irrevocably accepted the Closing Working Capital Statement and the Closing Financial Debt Statement, (b) the Closing Working Capital Statement and the Closing Financial Debt Statement will be final and binding upon Sellers and Buyer, and (c) within ten (10) days of the earlier of (1) the end of the Dispute Period, and (2) the delivery of an Acceptance Notice, the applicable payments indicated in Sections 1.3.6 and 1.3.7 below will be required to be made. If Sellers have delivered to Buyer a Dispute Notice within the Dispute Period, within ten (10) days after determination of the Dispute by the parties or by the Arbitrating Accountant, as relevant, the applicable payments indicated in Sections 1.3.6 and 1.3.7 below will be required to be made (the date on which the payments (if any) are to be made pursuant to Sections 1.3.6 and 1.3.7 is herein referred to as the “Working Capital True-Up Date”).

1.3.6 If the Closing Working Capital is less than the Preliminary Working Capital Payment, Sellers will pay to Buyer an amount of cash equal to the Dollar Equivalent of such deficit by wire transfer to an account designated in writing by Buyer (“Working Capital Shortfall”). If the Closing Working Capital exceeds the Preliminary Working Capital Payment, Buyer will pay to Sellers an amount of cash equal to the Dollar Equivalent of such excess, less any Withholding Tax at Working Capital True-Up Date, if any, with payment to be made by wire transfer to an account designated in writing by Sellers (“Working Capital Excess”). Any payments made to Buyer pursuant to this Section 1.3.6 shall be made without any deduction or withholding for tax or in respect of any amount of tax already withheld pursuant to Section 1.2 above.

1.3.7 Sellers will pay to Buyer an amount of cash equal to the Dollar Equivalent of the Closing Financial Debt, if any, by wire transfer to an account designated in writing by Buyer (the “Financial Debt Excess”). Any payments made to Buyer pursuant to this Section 1.3.7 shall be made without any deduction or withholding for tax or in respect of any amount of tax already withheld pursuant to Section 1.2 above.

1.4 Treatment of Purchase Price and Other Payments.

1.4.1 The parties agree that all payments made under this ARTICLE I and any other payments made either by Buyer to a Seller or a Sellers Indemnified Person or by Sellers to a Buyer or Buyer Indemnified Person under this Agreement will be made in accordance with the applicable Central Bank regulations in effect at the time of the payment. For the purposes of any remittance to be made hereunder to Sellers, Sellers agree to make available to Buyer any and all information readily available to Sellers and necessary in order to allow Buyer to legally effect such remittances outside Brazil, including the information and passwords to be made available by the Central Bank immediately prior to the Closing in respect of the registration of the Sellers’ investment in the Securities.

3

1.4.2 Except as set forth in Section 1.2, all payments made under this Agreement shall be made without any withholding or deduction for any Tax unless such withholding or deduction is required by law. In the event that Tax, other than a withholding Tax under Sections 1.2(e) and 1.2(f) or a Tax relating to income or gain, is required to be withheld or deducted on a payment made under this Agreement, the payer of such amount is required to pay to the recipient such additional amount as is necessary to ensure that the net amount actually received by the recipient will equal the full amount that the recipient would have received had no such deduction or withholding occurred.

ARTICLE II

Buyer hereby irrevocably and unconditionally waives any right, whether arising at law or in equity, to seek contribution, cost recovery, Losses, or any other recourse or remedy from Sellers, and hereby releases Sellers, from any claim, demand, or liability, with respect to any Tax Proceeding, except as otherwise provided in this Agreement, including Exhibit O.

7.6.4 Any Person entitled to seek indemnification under this Section 7.6 (a “Tax Indemnified Person”) will promptly notify the party (or parties) against whom such indemnification is sought (a “Tax Indemnifying Party”) in writing upon receipt by the Tax Indemnified Person of written notice of any inquiries, claims, assessments, audits or similar events with respect

27

to Taxes for which the Tax Indemnifying Party may be liable under this Section 7.6 (any such inquiry, claim, assessment, audit or similar event, a “Tax Matter”). The Tax Indemnifying Party, at its expense, will have the exclusive authority to represent the interests of the Transferred Business or the Retained Businesses, as applicable, with respect to any Tax Matter before the applicable Governmental Authority and will have the sole right to extend or waive the statute of limitations with respect to a Tax Matter and to control the defense, compromise or other resolution of any Tax Matter, including responding to inquiries, filing Tax Returns and settling audits; provided, however, that (a) if Sellers are the Tax Indemnifying Party, Sellers will not enter into any settlement of or otherwise compromise any Tax Matter that affects or may affect the Tax Liability of Buyer, the Companies or any Affiliate of the foregoing without the prior written consent of Buyer, which consent may not be unreasonably withheld or delayed and (b) if Buyer is the Tax Indemnifying Party, Buyer will not enter into any settlement of or otherwise compromise any Tax Matter that affects or may affect the Tax liability of Sellers, any Affiliate or the Retained Businesses without the prior written consent of Sellers, which consent may not be unreasonably withheld or delayed. The Tax Indemnifying Party will, in good faith, keep the Tax Indemnified Person reasonably informed with respect to the status of any Tax Matter and allow the Tax Indemnified Person to consult with it regarding the conduct of or positions taken in any such Tax Matter.

7.6.5 Any Tax Refunds and Credits that are received by Buyer or the Companies that relate to Taxes for which Sellers are responsible under Section 7.6.1 will be for the account of Sellers. Any Tax Refunds and Credits that are received by Sellers or their Affiliates that relate to Taxes for which Buyer is responsible under Sections 7.6.2 or 7.6.7 will be for the account of the Buyer. Any indemnities to be paid pursuant to this ARTICLE VII (collectively, “Payments”) will be settled promptly as follows: The Payments will be made to the relevant party. The amounts of the Payments will (a) first, be used to offset any amounts due to the relevant party as indemnification hereunder and (b) second, be paid to the relevant party.

7.6.6 (a) Buyer, the Companies and Sellers will cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to this ARTICLE VII and any Proceeding with respect to Taxes. Such cooperation will include the retention for a period of at least ten (10) years following the Closing Date, and (upon the other party’s request) the provision of, books, records and information that are reasonably relevant to any Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Buyer and Sellers further agree, upon request, to use their commercially reasonable efforts given the circumstances to obtain any certificate or other document from any governmental authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

(b) Notwithstanding any other provisions of this Agreement, the Companies will retain the original corporate, accounting, financial and tax books and records, ledgers, original entry, balance sheets and Tax Returns of the Companies.

7.6.7 Except as otherwise provided in this Agreement, all Taxes required to be paid in connection with the transactions provided for in this Agreement shall be borne by the party responsible for such Taxes under applicable Law.

7.7 Procedures for Third-Party Claims. Except with respect to Tax matters, which are exclusively governed by Section 7.6, the parties will follow the procedures set forth in this Section 7.7 with respect to any Third-Party Claim.

7.7.1 If any Person entitled to seek indemnification under Sections 4.6, 7.2, 7.3 or 7.5 (an “Indemnified Person”) receives notice of the assertion or commencement against such Indemnified Person of a Third-Party Claim with respect to which the party against whom such indemnification is being sought (an “Indemnifying Party”) is obligated to provide indemnification under this Agreement, the Indemnified Person will give such Indemnifying Party reasonably prompt written notice thereof. Such notice by the Indemnified Person will describe the Third-Party Claim in reasonable detail, will include copies of all available non-privileged material written evidence thereof and will indicate the estimated amount, if reasonably practicable, of the Losses that have been or may be sustained by the Indemnified Person. The Indemnifying Party will have the right to participate in or, by giving written notice to the Indemnified Person, to assume, the defense of any Third-Party Claim at such Indemnifying Party’s own expense and by such Indemnifying Party’s counsel (reasonably satisfactory to the Indemnified Person), and the Indemnified Person will cooperate in good faith in such defense.

7.7.2 If, within ten (10) days after giving notice of a Third-Party Claim to an Indemnifying Party pursuant to Section 7.7.1, an Indemnified Person receives written notice from the Indemnifying Party that the Indemnifying Party has elected

28

to assume the defense of such Third-Party Claim as provided in the last sentence of Section 7.7.1, the Indemnifying Party will not be liable for any legal expenses subsequently incurred by the Indemnified Person in connection with the defense thereof; provided, however, that if the Indemnifying Party fails to take reasonable steps necessary to defend diligently such Third-Party Claim within ten (10) days after receiving written notice from the Indemnified Person that the Indemnified Person reasonably believes the Indemnifying Party has failed to take such steps, if the Indemnifying Party has not undertaken fully to indemnify the Indemnified Person in respect of all Losses relating to the matter, or if the Indemnified Person reasonably believes that the counsel selected by the Indemnifying Person has a conflict of interest with the Indemnified Person or otherwise is not likely to adequately defend the Indemnified Persons interest, the Indemnified Person may assume its own defense and may engage its own counsel, and the Indemnifying Party will be liable for all reasonable costs and expenses paid or incurred in connection therewith. Without the prior written consent of the Indemnified Person, the Indemnifying Party will not enter into any settlement of any Third-Party Claim which would lead to liability or create any financial or other obligation on the part of the Indemnified Person for which the Indemnified Person is not entitled to indemnification hereunder, or which provides for injunctive or other non-monetary relief applicable to the Indemnified Person or does not include an unconditional release of all Indemnified Persons. If a firm offer is made to settle a Third-Party Claim (a) without leading to liability or the creation of a financial or other obligation on the part of the Indemnified Person for which the Indemnified Party is not entitled to indemnification hereunder and (b) without providing for injunctive or other non-monetary relief, and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party will give written notice to the Indemnified Person to that effect. If the Indemnified Person fails to consent to such firm offer within twenty (20) days after its receipt of such notice, the Indemnified Person may continue to contest or defend such Third-Party Claim and, in such event, the maximum liability of the Indemnifying Party as to such Third-Party Claim will not exceed the amount of such settlement offer. Sellers and Buyer will make available to each other, their counsel and accountants (and, subsequent to the Closing, Buyer will cause the Companies to make available to Sellers), all non-privileged information and documents reasonably available to them that relate to any Third-Party Claim that may be subject to indemnification hereunder and to render to each other such assistance as may reasonably be required in order to ensure the proper and adequate defense of any such claim.

7.8 Direct Claims. Any claim by an Indemnified Person on account of Losses that does not involve a Third-Party Claim will be asserted by giving the Indemnifying Party reasonably prompt written notice thereof. Such notice by the Indemnified Person will describe the claim in reasonable detail, will include copies of all available non-privileged material written evidence thereof and will indicate the estimated amount, if reasonably practicable, of Losses that have been or may be sustained by the Indemnified Person. The Indemnifying Party will have a period of ten (10) days or such shorter period required by applicable Law within which to respond in writing to such claim. If the Indemnifying Party rejects such claim or does not so respond within such ten-day period (or lesser applicable period of time), the Indemnifying Party will be deemed to have rejected such claim, and the Indemnified Person will then be free to pursue such remedies as may be available to the Indemnified Person on the terms and subject to the provisions of this Agreement.

7.9 Limitations on Claims for Indemnification. The rights of Buyer Indemnified Persons and Sellers Indemnified Persons to indemnification under this ARTICLE VII will be limited as follows:

7.9.1 The amount of Losses for which indemnification is provided under Sections 7.2, 7.3 and 7.5.1 will be computed net of any insurance proceeds actually received by the Indemnified Person in respect of such Losses, reduced by all costs and expenses related thereto and any premium increase or expense resulting therefrom.

7.9.2 Any failure to give timely notice or to include any required information in any notice as provided in Section 7.6 or 7.7 will not affect the rights or obligations of any party hereunder, except and only to the extent that, as a result of such failure, any party that was entitled to receive such notice was deprived of its right to recover any payment under its applicable insurance coverage or was otherwise materially prejudiced as a result of such failure.

7.9.3 No Buyer Indemnified Person, including Guarantor, will be entitled to make a claim against Sellers under Section 7.2 in respect of a breach of the Commercial Warranties unless the amount of the liability pursuant to that claim (and for these purposes, a number of claims arising out of the same or related facts, events and circumstances may be aggregated and form a single claim) exceeds R$750,000 (in which case Buyer shall be able to claim the whole amount of such claim and not merely the excess) and until the aggregate amount of Losses incurred by Buyer Indemnified Persons and indemnifiable and reimbursable under Section 7.2(a) in respect of a breach or breaches of the Commercial Warranties exceeds R$7,500,000, in which event Buyer Indemnified Persons may assert rights thereunder to the full extent of Losses in respect of the amount in excess of R$7,500,000, up to, but not in excess of, an amount equal to ten percent (10%) of the Purchase Price (excluding

29

adjustments made pursuant to Section 7.9.7). For the avoidance of doubt, the liability of Sellers for all Losses arising pursuant to Section 7.2 shall be unlimited except as provided in this Section 7.9.3. Losses incurred by Buyer in respect of a breach or breaches of Section 4.1(a) (as to which a claim may validly be made under Section 10.13) shall be counted for purposes of the calculations, thresholds and limits under this Section 7.9.3 as if it were a breach of the Commercial Warranties.

7.9.4 Sellers will not be liable for any claim for breach of a Commercial Warranty if and to the extent that the fact, matter, event or circumstance giving rise to such claim was disclosed in this Agreement (including the Schedules and Exhibits hereto) or the Data Room; provided, however, the foregoing shall not be construed to relieve Sellers of any obligations or Buyer of any rights expressly stated in Section 3.4.

7.9.5 The Indemnified Person will cooperate with the Indemnifying Party with respect to resolving any claim or liability with respect to which the Indemnifying Party is obligated to indemnify the Indemnified Person under Sections 7.2 and 7.3, including by making commercially reasonable efforts considering the circumstances to mitigate any Losses; provided, however, that the Indemnified Person shall not be required to make such efforts if they would be detrimental in any material respect to the Indemnified Person. In the event that the Indemnified Person fails to make such commercially reasonable efforts to mitigate Losses, then (unless the proviso to the foregoing sentence shall be applicable) notwithstanding anything else to the contrary contained herein, the Indemnifying Party shall not be required to indemnify the Indemnified Person for any Loss that could reasonably be expected to have been avoided if the Indemnified Person had made such efforts.

7.9.6 All payments to be made by an Indemnifying Party in respect of any claims under Section 7.2, 7.3, 7.5 or 7.6 shall be made in Dollars and, if such payments are denominated in Reais, the Indemnifying Party will pay the Indemnified Person an amount in cash equal to the Dollar Equivalent of the payment required to be made.

7.9.7 Any offset made or amount paid to a Buyer Indemnified Person or a Sellers Indemnified Person under this ARTICLE VII will be treated as an adjustment to the Purchase Price.

7.9.8 None of the limitations contained in this Section 7.9 shall apply to any claim to the extent that the claim (or the delay in discovery of it) (i) is the consequence of, or is increased as a consequence of, the knowingly dishonest or deliberate misstatement or concealment or other fraud by Sellers or any of their Affiliates (other than the Companies) or any officer or employee (or former officer or employee) of Sellers or any of their Affiliates (other than the Companies), or (ii) concerns a breach of any of the Tax, Title and Capacity Warranties.

ARTICLE VIII

8.1 Termination of Agreement. This Agreement may be terminated at any time prior to the Closing as follows:

(a) By mutual consent in writing of Buyer and Sellers;

(b) By Sellers, on the one hand, or Buyer, on the other hand, if the conditions contained in Sections 5.1, 5.2, 6.1 and 6.2 have not been satisfied or waived by Sellers or Buyer (as applicable) in accordance therewith on or before February 28, 2009 (the “Outside Date”); provided, that if on the Outside Date any or all of the conditions to Closing set forth in Sections 5.1.2, 5.1.3, 6.1.2 and 6.1.3 (the “Divestiture Transactions and IT Separation Conditions”) have not been fulfilled or waived but all other conditions (other than those steps customarily taken and completed on the Closing Date) to the Closing have been fulfilled or waived, then either party may extend the Outside Date for an additional period up to June 30, 2009 (the “Extended Outside Date”); provided, however, that the right to terminate this Agreement pursuant to this Section 8.1(b) will not be available to any party whose failure to perform any of its obligations under this Agreement materially contributed to the failure of the condition(s) to Closing being satisfied by the relevant date referred to in this Section 8.1(b).

No assignment will relieve the assignor of its obligations or liabilities hereunder without the prior written consent of the other parties hereto, and no assignment will occur without the prior written consent of the other parties, except, for the avoidance of doubt, for any assignment of assets that are to be part of the Retained Businesses, required to implement the Divestiture Transactions.

All arbitration proceedings, including but not limited to written submissions, hearings, etc., shall be conducted in English. All arbitration hearings and any related proceedings shall take place in Miami, Florida. Any arbitration awards may be entered as judgments in any State Court in New York, in the Federal District Courts of New York or any other court having jurisdiction and enforcement of such judgments may be made through all means permissible and available in such courts. For the purpose of enforcing any arbitration award arising from this Agreement, the parties irrevocably and unconditionally consent to the jurisdiction and venue of such courts. However, no party waives its right to remove any action to a Federal District Court.

10.7 Severability. If any provision of this Agreement or the application of any such provision to any Person or circumstance is held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction, the remainder of the provisions of this Agreement (or the application of such provision in other jurisdictions or to Persons or circumstances other than those to which it was held invalid, illegal or unenforceable) will in no way be affected, impaired or invalidated, and to the extent permitted by applicable Law, any such provision will be restricted in applicability or reformed to the minimum extent required for such to be enforceable. This provision will be interpreted and enforced to give effect to the original written intent of the parties prior to the determination of such invalidity or unenforceability.

10.8 Entire Agreement. This Agreement (including the Schedules and Exhibits) together with the Confidentiality Agreement and the Ancillary Agreements constitute the entire agreement among the parties and supersede any prior understandings or agreements by or among the parties, written or oral, related to the subject matter hereof.

10.9 Construction. The parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties, and no presumption or burden of proof will arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement. Unless the context otherwise requires, (a) any reference to any federal, state, local or foreign statute or law will be deemed also to refer to all rules and regulations promulgated thereunder, (b) the use of the singular will include the plural, the use of the masculine will include the feminine, and vice versa, (c) all references to Sections, Articles, Exhibits or Schedules are to Sections, Articles, Exhibits or Schedules of or to this Agreement, (d) each of the Schedules will apply only to the corresponding Section or subsection of this Agreement, (e) the word “including” will mean including without limitation, and, (f) any definition of or reference to any agreement, contract, document, instrument or other record herein shall be construed as referring to such agreement, contract, document, instrument or other record as from time to time amended, supplemented, restated or otherwise modified (subject to any restrictions on such amendments, supplements or modifications set forth herein).

10.10 Effect of Due Diligence and Related Matters.

(a) Buyer acknowledges that it is a sophisticated entity that was advised by legal counsel and financial advisors and, to the extent it deemed necessary, other advisors in connection with this Agreement and has conducted its own independent review and evaluation of the Transferred Business.

(b) Buyer acknowledges that (i) the Properties and Transferred Business have at some time been used for the storage, distribution or processing of petroleum products, oils and fuels or other chemical substances, contaminants, pollutants, substances or materials which may still be present at, in, upon, under or emanating from each Property; and (ii) the vast majority of the retail, commercial and industrial, and terminal sites that have comprised the Transferred Business have not undergone physical environmental site assessments by Sellers, their Affiliates, or their respective consultants, and environmental remediation or cleanup may be required with respect to such Properties and those Properties that have undergone physical environmental site assessments by Sellers, their Affiliates, or their respective consultants.

(c) Buyer acknowledges that (i) it relies at its own risk on the contents of any report, plan and/or other written material and/or information either disclosed to it (in the Data Room or otherwise) and/or orally communicated to it by Sellers or any other Person as to any Environmental Condition related to the Transferred Business or Properties, and (ii) except to the extent expressly provided in Sections 3.2.5 and 3.2.14(b), Sellers make no representations whatsoever as to the accuracy, completeness or reliability of any such environmental information as prepared by third parties, whether obtained from Seller or another source, nor as to any such environmental information prepared by Sellers or their Affiliates in reliance upon information from third parties.

42

(d) Buyer covenants and agrees that there are no representations or warranties by or on behalf of any of Sellers, their Affiliates or their representatives in respect of the subject matter of this Agreement except for those expressly set forth in this Agreement and the Ancillary Agreements.

(e) Except to the extent expressly provided in Sections 3.2.5 and 3.2.14(b), neither Sellers, nor the Companies, nor any Affiliate of Sellers make any representations or warranties (i) as to any Environmental Condition relating to the past, current or future facilities, properties or operations of the Companies, their Subsidiaries or their Affiliates (or their respective predecessors), including any such matter arising under Environmental Law, any analogous Law or any other applicable Law, nor shall the representations and warranties contained in this Agreement be construed to do so, or (ii) as to the physical state or condition of any of the facilities associated with the Transferred Business, including any property and equipment used in the marketing and sales of hydrocarbon products nor shall the representations and warranties contained in this Agreement be construed to do so (all of which are, for the avoidance of doubt, but without prejudice to its rights under this Agreement or any of the Ancillary Agreements, to be acquired by Buyer on an “AS IS, WHERE IS, AND WITH ALL FAULTS” basis).

(f) Nothing in this Section 10.10 eliminates or reduces any right expressly provided to Buyer in this Agreement; provided, however, it is acknowledged that the only rights of any kind provided to Buyer hereunder with respect to Environmental matters are stated in Sections 3.2.5 and 3.2.14(b).

10.11 Buyer’s Rights to Equitable Relief; Sole Remedy. Notwithstanding any other provision of this Agreement, other than as provided in Article VIII and Section 10.13, Buyer’s sole and exclusive remedy with respect to any breach or attempted breach of the covenants contained in Sections 4.1, 4.2, 4.3, 4.4, 4.6, 4.7, 4.8, 4.9, 4.10, 4.11, 4.12 or 4.15 and Paragraph 5 of Exhibit F (as such paragraph imposes obligations on Sellers) shall be a right to seek, in an arbitration proceeding pursuant to Section 10.6, equitable relief, including the remedy of specific performance. Without waiver of any other potential argument, Sellers agree to not assert that an adequate remedy at law is available with respect to any attempt by Buyer to seek relief in accordance with this Section 10.11. Notwithstanding the foregoing, Buyer’s remedies for any post-Closing breaches by Sellers of Sections 4.6(d), 4.6(e), 4.15 or Paragraph 5 of Exhibit F, shall not be limited by this Section 10.11.

Notwithstanding any other provision of this Agreement, other than as provided in Article VIII, Sellers sole and exclusive remedy with respect to breach or attempted breach of the covenants contained in Sections 4.8, 4.10 or 4.13 and Paragraph 5 of Exhibit F (as such paragraph imposes obligations on Buyer) shall be a right to seek, in an arbitration proceeding pursuant to Section 10.6, equitable relief, including the remedy of specific performance. Without waiver of any other potential argument, Buyer agrees to not assert that an adequate remedy at law is available with respect to any attempt by Sellers to seek relief in accordance with this Section 10.12. Notwithstanding the foregoing, Sellers’ remedies for any post-Closing breaches by Buyer of Sections 4.6(d), 4.6(e), or Paragraph 5 of Exhibit F shall not be limited by this Section 10.12.

10.13 Breach of Section 4.1(a).

(a) Subject to the terms and conditions of this Section 10.13 effective from and after the Closing, Sellers, jointly and severally, will indemnify, defend and hold harmless each Buyer Indemnified Person from and against, and will reimburse them for, any and all Losses resulting from or arising in connection with any breach of any covenant of Sellers prior to the Closing contained in Section 4.1(a) of this Agreement.

(b) Any claim by Buyer for breach of Section 4.1(a) is deemed to be forever waived unless: (i) in the case of such claims known by Buyer prior to Closing, the claim is asserted by Buyer giving Sellers prompt written notice thereof, but in no event on or after the Closing Date; and (ii) in the case of such claims which were not known by Buyer prior to Closing, the claim is asserted by Buyer giving Sellers notice within sixty (60) days following Closing. All such notices shall set out all material relevant details as are then reasonably available as to the specific matter in question and which details shall establish either actual damages or obligations or at least a reasonable likelihood of actual damages or obligations. Sellers shall have a period of ten (10) days within which to respond in writing to such claim. If Sellers reject such claim or do not so respond within such ten (10) day period, Sellers will be deemed to have rejected such claim, and Buyer may file a claim in accordance with Section 10.6 so long as such a filing occurs within thirty (30) days following the date of Sellers’ rejection of the claim.

43

(c) The terms of Section 7.9.3 shall apply equally to any claim made under this Section 10.13.

10.14 Third-Party Beneficiaries. Except with respect to the right to indemnification under Sections 4.6(b) and 4.16(a), ARTICLE VII and Section 10.13, nothing expressed or implied in this Agreement is intended, or will be construed, to confer upon or give any Person, other than the parties hereto, any rights or remedies under or by reason of this Agreement.
