(b) If Cementos disagrees with any calculations set forth in the Post-Closing Certificate, Cementos may deliver to Summit, within 45 days following the date on which the Post-Closing Certificate was delivered (the “Objection Period”), a written notice (the “Dispute Notice”) setting forth Cementos’s calculation of the disputed amount, a description in reasonable detail of the grounds for each such disagreement and Cementos’s alternative calculation of the Closing Consideration (each such item or amount as to which Cementos disagrees and set forth in the Dispute Notice, an “Item of Disagreement”). Except for those Items of Disagreement set forth in the Dispute Notice delivered during the Objection Period, Cementos shall be deemed to have agreed with all other items and amounts set forth in the Post-Closing Certificate, which items and amounts shall be final, binding and conclusive for all purposes hereunder, and no Party

may thereafter dispute any item or amount not set forth in such Dispute Notice. Cementos may only deliver one Dispute Notice and, if Cementos does not timely deliver a Dispute Notice, the Post-Closing Certificate, and the items and amounts therein, shall be deemed final, binding and conclusive for all purposes hereunder, and no Party may thereafter dispute any item or amount not set forth in such Dispute Notice.

(c) In the event that Cementos delivers the Dispute Notice to Summit within the Objection Period, Summit and Cementos will negotiate in good faith to resolve all Items of Disagreement. If, after a period of 30 days (or any mutually agreed extension thereof) following the date on which such Dispute Notice is delivered, Summit and Cementos have not resolved each such Item of Disagreement, then at the request of either Summit or Cementos all such Items of Disagreement that remain unresolved shall be submitted to the Resolution Accountants in writing. Summit and Cementos shall, and shall cause their respective Representatives to, reasonably cooperate with the Resolution Accountants so as to enable them to make their determination as quickly and as accurately as practicable. The Parties agree that (i) the Resolution Accountant shall consider only those items or amounts in the Post-Closing Certificate as to which Cementos has disagreed in a Dispute Notice and which have not been resolved prior to submission to the Resolution Accountant, (ii) no Party shall have any ex parte meetings or communications with the Resolution Accountants, (iii) the Resolution Accountants shall not be entitled to hold any hearings or take or order the taking of depositions or other testimony, (iv) the Resolution Accountants shall decide all remaining Items of Disagreement solely based on the terms and standards set forth in this Agreement and in the Accounting Policies and (v) with respect to each matter submitted to it, the Resolution Accountant shall not resolve such matter in a manner that is more favorable to Summit’s position than the Post-Closing Certificate or more favorable to Cementos’s position than the Dispute Notice. Summit and Cementos shall use reasonable best efforts to obtain from the Resolution Accountants a resolution of all Items of Disagreement that remain unresolved as promptly as reasonably practicable after the date on which the Resolution Accountants are engaged. The Resolution Accountants shall render such resolution in writing, and the calculation of the remaining Items of Disagreement referred to the Resolution Accountants and the Final Aggregate Cash Consideration as determined by the Resolution Accountants shall be binding upon the Parties absent manifest error or actual intentional common law fraud (and not constructive fraud or other similar claims based on constructive knowledge, negligent misrepresentation, recklessness or similar theories). The costs, fees and expenses of the Resolution Accountants shall be borne by Summit and Cementos (on behalf of the Argos Parties and included as a Company Transaction Expense) in the same proportion as the aggregate amount of the Items of Disagreement submitted to the Resolution Accountants that are unsuccessfully disputed by each such Party (as finally determined by the Resolution Accountants) bears to the total amount of such Items of Disagreement so submitted. For example, if Cementos timely submits a Dispute Notice for $1,000, and if Summit contests only $500 of such amount, and the Resolution Accountants ultimately resolve the dispute by awarding Cementos $300 of the $500 contested, then the costs and expenses of the Resolution Accountants will be allocated 60% (i.e., 300/500) to Summit and 40% (i.e., 200/500) to Cementos. All other costs, fees and expenses incurred by the Parties in connection with resolving such dispute shall be borne by the party incurring such cost and expense. The dispute

resolution by the Resolution Accountants under this ‎Section 2.06 shall constitute an expert determination and shall not constitute an arbitration. The Resolution Accountant shall have exclusive jurisdiction over, and resort to the Resolution Accountant as provided in this Section 2.06 shall be the only recourse and sole and exclusive remedy of the parties against one another with respect to, any disputes arising out of or relating to the adjustments pursuant to this Section 2.06. Any disputes not within the scope of the disputes to be resolved by the Resolution Accountant pursuant to this Section 2.06 (as well as any disputes about the scope of disputes to be resolved by the Resolution Accountants pursuant to this Section 2.06) shall be resolved pursuant to Section 12.07.

Section 2.07. Post-Closing Closing Consideration Adjustment. (a) Promptly following the determination of the Final Aggregate Cash Consideration (but in any event within five Business Days of such determination), (i) if the Final Aggregate Cash Consideration exceeds the Estimated Aggregate Cash Consideration, Summit shall pay to Argos Parties or its designee, the amount of such excess by wire transfer of immediately available funds to an account designated by Cementos or (ii) if the Final Aggregate Cash Consideration is less than the Estimated Aggregate Cash Consideration, then Cementos and the Argos Parties shall be obligated, on a joint and several basis, to pay such amount to Summit, such amount, by wire transfer of immediately available funds to an account designated by Summit. Any amounts payable pursuant to this Section 2.07 shall be treated for Tax purposes as an adjustment to the Closing Consideration unless required otherwise by a change in Tax law, or final determination by the appropriate Governmental Authority or court .

Section 2.08. Share Capital Adjustments; Lost Certificates; Fractional Shares. (a) In the event of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into capital stock), reorganization, reclassification, combination, recapitalization or other like change with respect to the Purchased Shares or Summit Common Stock occurring after the date hereof and prior to the Closing, all references herein to specified numbers of shares of any class or series affected thereby, and all calculations provided for that are based upon numbers of shares of any class or series (or prices therefor) affected thereby, shall be equitably adjusted to the extent necessary to provide the parties the same economic effect as contemplated by this Agreement prior to such stock split, reverse stock split, stock dividend, reorganization, reclassification, combination, recapitalization or other like change.

(b) Legend. Any certificates or book entry entitlements representing the shares of Summit Common Stock to be issued pursuant to this Agreement shall bear the legend set forth (along with any other legends that may be required under Applicable Law) in Section 5.03 of the Stockholder Agreement.

Section 2.09. Withholding. Notwithstanding any provision contained herein to the contrary, Summit, any Affiliate of Summit, and any other Person at the direction of Summit, shall be entitled to deduct and withhold from any amounts otherwise payable to any Person pursuant to this Agreement or any other Transaction Documents such amounts as it is required to

deduct and withhold with respect to the making of such payment under any provision of Applicable Law; provided that if Cementos and the Argos Parties deliver to Summit, on or before the Closing Date, the Closing FIRPTA Certificate pursuant to Section 2.05(b)(vi), then no such amounts will be required to be withheld under Section 1445 of the Code. If Cementos and the Argos Parties do not deliver such Closing FIRPTA Certificate pursuant to the previous sentence, the Closing shall nonetheless proceed, and Summit’s sole remedy shall be to withhold such amount as required pursuant to Section 1445 of the Code and remit such amounts to the IRS, in each case, in accordance with Schedule IV attached hereto. Any amounts so deducted and withheld by Summit, any of Summit’s Affiliates or any Person at the direction of Summit, as the case may be, shall be treated for all purposes of this Agreement or such other Transaction Documents as having been paid to such Person in respect of which such deduction or withholding was made. If Summit determines that withholding is required pursuant to this Section 2.09 (other than pursuant to Section 1445 of the Code), then at least 5 Business Days prior to making any such deduction or withholding, Summit shall provide notice to Cementos of the amounts subject to withholding and shall cooperate with Cementos to eliminate or minimize to the greatest extent practicable the basis for such deduction or withholding.

Except for Summit’s rights under this Agreement, no Person has any Contract or any right or privilege (whether by Applicable Law or under any preemptive or contractual right) for the purchase or acquisition of any Equity Securities of any ANAC Company.

The Audited Financial Statements and the Interim Financial Statements have each been prepared in conformity with U.S. GAAP applied on a consistent basis and fairly present, in all material respects, the consolidated financial position of the Company and each of its Subsidiaries as of the dates thereof and their consolidated results of operations, cash flows and members’ equity for the periods then ended (subject, in the case of the Interim Financial Statements, to normal year-end adjustments which are not material individually or in the aggregate to the Company and each of its Subsidiaries and the absence of footnote disclosure which are not material and adverse individually or in the aggregate to the ANAC Companies, taken as a whole). Prior to the date hereof, the Company has made available to Summit true and complete copies of each of the Audited Financial Statements and Interim Financial Statements. No auditor of any Audited Financial Statements has indicated to any ANAC Company that it will withdraw its audit opinion with respect to such Audited Financial Statements and no ANAC Company has determined that it is required to restate any Audited Financial Statements or any Interim Financial Statements.

There are no material deficiencies or material weaknesses in the design or operation of internal control over financial reporting relating to the ANAC Companies which are reasonably likely to adversely affect the ANAC Companies’ ability to record, process, summarize and report financial information, and any such prior deficiencies or weaknesses identified since January 1, 2021 have been adequately disclosed to the ANAC Companies’ auditors. Since January 1, 2021, the ANAC Companies have not identified and have not been advised by their auditors of any fraud or allegation of fraud, whether or not material, that involves management or other employees of the Company or any of its Subsidiaries who have a significant role in the ANAC Companies’ internal controls over financial reporting.

With respect to all Material Contracts, none of the ANAC Companies nor, to the Knowledge of the Company, any other party to any such Contract is in breach thereof or default thereunder and there does not exist under any Material Contract any event which, with the giving of notice or the lapse of time, would constitute such a breach or default by any ANAC Company or, to the Knowledge of the Company, any other party to such Material Contract (and none of the ANAC Companies have received any written claim or notice of (x) any purported breach or default of any Material Contract or any dispute thereunder or (y) regarding the non-renewal or partial or total termination of any Material Contract), in each case except for such breaches, defaults and events which would not, individually or in the aggregate, reasonably be expected to be material to the ANAC Companies, taken as a whole. Prior to the date hereof, the Company has made available to Summit true and complete copies of each Material Contract, and all amendments, extensions, renewals, guaranties and other agreements with respect thereto.

Cementos will be directly or indirectly acquiring Summit Common Stock representing the Aggregate Stock Consideration and Summit Preferred Stock for the purpose of investment and not with a view to, or for resale in connection with, the distribution thereof in violation of applicable federal, state or provincial securities laws. Cementos acknowledges that the issuance of Summit Common Stock representing the Aggregate Stock Consideration and Summit Preferred Stock hereunder has not been registered under the 1933 Act or any state securities laws, and that Summit Common Stock representing the Aggregate Stock Consideration and Summit Preferred Stock may not be sold without registration under the 1933 Act, pursuant to an exemption from the 1933 Act or in a transaction not subject thereto.

Section 4.08.   Accredited Investor; Independent Investigation.

(a)   Cementos is knowledgeable, sophisticated and experienced in business and financial matters, is experienced in evaluating investments in companies such as Summit and qualifies as an “accredited investor” as defined in Rule 501(a) of Regulation D promulgated under the Securities Act of 1933.

63

(b)   Cementos has been afforded access to information about Summit and the financial condition, results of operations, business, property and management of Summit sufficient to enable it to evaluate its investment in Summit Common Stock and Summit Preferred Stock. Cementos has reviewed the financial statements of Summit and such other documents as Cementos has reasonably deemed advisable or necessary in connection with making its, his or her investment decision. Cementos and its advisors, if any, have been afforded the opportunity to ask questions of Summit. Cementos understands that there may be certain consequences under U.S. and other tax laws resulting from an investment in Summit Common Stock and Summit Preferred Stock, and has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its, his or her acquisition of Summit Common Stock and Summit Preferred Stock.

(c)   Cementos understands that its investment in Summit Common Stock and Summit Preferred Stock involves a high degree of risk and such shares of Summit Common Stock and Summit Preferred Stock are, therefore, a speculative investment. Cementos is able to bear the economic risk of its investment in such Summit Common Stock and Summit Preferred Stock for an indefinite period of time, and is presently able to afford the complete loss of such investment.

(d)   Cementos acknowledges that it, he or she has conducted to its, his or her satisfaction an independent investigation of the financial condition, results of operations, assets, liabilities, properties, taxes, prospects, creditworthiness, status, affairs and projected operations of Summit and, in making the determination to acquire Summit Common Stock and Summit Preferred Stock has relied solely on the results of its independent investigation and appraisal, and is not relying (for purposes of making any investment decision or otherwise) upon any advice, counsel or representations (whether written or oral) of Summit or any of its officers, employees, agents, advisors or affiliates, other than the representations and warranties expressly set forth in Article 5 and the representations and warranties expressly set forth in the other Transaction Documents or the representations and warranties set forth in the certificates required to be delivered pursuant to Section 9.02(d). Cementos further acknowledges that none of Summit, any of its Affiliates or any of its Representatives has made any representations or warranties, either expressed or implied, as to the accuracy or completeness of any information regarding Summit furnished or made available to the Argos Party and its Representatives.

(e)   Cementos is not acquiring Summit Common Stock or Summit Preferred Stock as a result of any advertisement, article, notice or other communication regarding Summit Common Stock or Summit Preferred Stock or ordinary shares of Summit published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general advertisement, and the offer to purchase Summit Common Stock and Summit Preferred Stock was directly communicated to Cementos by Summit.

64

(f)   Cementos understands that (i) Summit Common Stock and Summit Preferred Stock that it, he or she is acquiring have not been and will not be registered under the 1933 Act and are “restricted securities” within the meaning of Rule 144(a)(3) under the 1933 Act as they are being acquired from Summit in a transaction not involving a public offering and that under such laws and applicable regulations Summit Common Stock and Summit Preferred Stock may not be offered or sold absent registration under the 1933 Act except pursuant to an exception from, or in a transaction not subject to, the registration requirements of the 1933 Act and in compliance with any applicable securities laws of any state or territory of the United States and of any other jurisdiction, and that no representation can be made as to the availability of the exemption provided by Rule 144 under the 1933 Act. Each Argos Party understands and acknowledges that Summit shall have no obligation to recognize any offer, sale, pledge or other transfer made other than in compliance with the restrictions on transfer set forth in the Stockholder Agreement and that Summit may make notation on its records or give instructions to any transfer agent of Summit Common Stock and Summit Preferred Stock in order to implement such restrictions. Cementos, in making its decision to purchase Summit Common Stock, has made its investment decision regarding its acquisition of Summit Common Stock and Summit Preferred Stock (including, without limitation, the income Tax consequences of acquiring, owning or disposing of Summit Common Stock and Summit Preferred Stock in light of Cementos’s particular situation and tax residence(s) as well as any consequences arising under the laws of any taxing jurisdiction).

(g)   Cementos understands that Summit, as the issuer of Summit Common Stock and Summit Preferred Stock, and its affiliates are relying upon the truth and accuracy of, and such Argos Party’s compliance with, the representations and agreements contained in this ‎Section 4.08 for the purpose of determining whether the offer, sale and issuance of Summit Common Stock and Summit Preferred Stock meets the requirements for an applicable exemption from registration under the 1933 Act.

Section 4.09.   No Reliance.

(b)   As of the date of this Agreement, (i) the Debt Commitment Letter is in full force and effect (except as limited by the Enforceability Exception) and constitutes a legal, valid and binding obligation of Summit and, to the Knowledge of Summit, the other parties thereto and (ii) assuming due and valid execution by each other party thereto, the Debt Commitment Letter is enforceable against Summit and to the knowledge of Summit, the other parties thereto in accordance with its terms, subject to the Enforceability Exception. As of the date hereof, except as not prohibited under Section 7.08(b), the Debt Commitment Letter has not been amended or modified in any respect, no provisions or rights thereunder have been waived and the respective commitments contained therein have not been withdrawn, rescinded or otherwise modified in any respect and, to the Knowledge of Summit, no such withdrawal, rescission or modification is contemplated. As of the date hereof, no event has occurred which, with or without notice, lapse of time or both, would constitute a default or breach under the Debt Commitment Letter on the part of Summit or, to the knowledge of Summit, any other party thereto. There are no conditions precedent or other contingencies directly or indirectly related to the funding of the full amount of the Debt Financing required to consummate the transactions contemplated by this Agreement other than the conditions precedent expressly set forth in the Debt Commitment Letter, and Summit has no reason to believe that, as of the date of this Agreement, assuming satisfaction of the conditions set forth in Article 9, (i) it or any other party thereto will not be able to satisfy on a timely basis any term or condition of the Debt Commitment Letter, including any condition to the closing of the Debt Financing, or (ii) the amount of the Debt Financing required to consummate the transactions contemplated by this Agreement will not be made available to Summit at or prior to the Closing. As of the date of this Agreement, other than the Debt Commitment Letter and any customary engagement letters or customary fee letters in each case with respect to the Debt Financing (none of which adversely affect the conditionality, enforceability or availability of the Debt Financing), there are no side letters or other contracts, arrangements or understandings directly or indirectly related to the funding or investing, as applicable, of the full amount of the Debt Financing or that would reasonably be expected to affect the availability of the Debt Financing on the Closing Date. The aggregate proceeds of the Debt Financing when funded in accordance with the Debt Commitment Letter are in an amount sufficient to (1) consummate the Closing upon the terms contemplated by this Agreement and (2) pay all amounts payable by Summit on the Closing Date in connection with the consummation of the transactions contemplated by this Agreement. As of the date hereof, Summit has fully paid, or caused to be paid, any and all commitment fees and any and all other fees and expenses, in each case as are required to be paid on or prior to the date hereof pursuant to the terms of the Debt Commitment Letter. Summit expressly acknowledges and agrees that its ability to obtain any financing (including the Debt Financing) is not a condition to its obligations under this Agreement.

(b)   Exceptions. Notwithstanding anything contained in this Section 6.04 to the contrary, at any time prior to receipt of the Summit Stockholder Approval:

In addition, nothing contained in this Agreement shall prevent Summit or the Summit Board (or any committee thereof) from (1) taking and disclosing to Summit’s stockholders a position contemplated by Rule 14d-9 and Rule 14e-2(a) promulgated under the 1934 Act (or any similar communication to stockholders in connection with the making or amendment of a tender offer or exchange offer), (2) making any legally required disclosure to stockholders with regard to the Transactions or any offer, inquiry, proposal or indication of interest with respect to a Summit Acquisition Proposal, (3) issuing a “stop, look and listen” disclosure or similar communication of the type contemplated by Rule 14d-9(f) under the 1934 Act or (4) contacting and engaging in discussions with any person or group and their respective Representatives who has made an offer, inquiry, proposal or indication of interest with respect to a Summit Acquisition Proposal that was not solicited in breach of this Section 6.04 solely for the purpose of clarifying such offer, inquiry, proposal or indication of interest and the terms thereof or informing such Third Party of the restrictions imposed by this ‎Section 6.04; provided, that nothing in this Section 6.04(c) will be deemed to permit Summit or the Summit Board to effect a Summit Adverse Recommendation Change other than in accordance with Section 6.04(e).

(d)   Required Notices. Prior to the earlier of the termination of this Agreement pursuant to Article 11 and the Closing, Summit shall (i) notify Cementos promptly (and in any event no later than 24 hours) (A) of the receipt by Summit of any Summit Acquisition Proposal (including any bona fide offer, inquiry, proposal or indication of interest with respect to thereto) or any amendment or modification to the material terms of any Summit Acquisition Proposal and such notice shall include, to the extent then known to Summit, the identity of the Person making such Summit Acquisition Proposal (or bona fide offer, inquiry, proposal or indication of interest with respect to thereto) and the material terms and conditions thereof (along with unredacted copies of all material proposed transaction agreements and other material documents provided in connection therewith) and (B) of any request for nonpublic information relating to Summit or any of its Subsidiaries or for access to the business, properties, assets, books or records or personnel of Summit or any of its Subsidiaries by any Third Party that has notified Summit that

To the extent that it has not done so prior to the date hereof, Summit shall promptly deliver a written notice to each such Person providing only that Summit is ending all discussions and negotiations with such Person with respect to any Summit Acquisition Proposal, or proposal or transaction that would reasonably be expected to lead to an Summit Acquisition Proposal and informing such Persons of the obligations undertaken in this Section 6.04, which notice shall, to the extent such Person has executed a confidentiality agreement in connection with its consideration of a Summit Acquisition Proposal, also request the prompt return or destruction of all confidential information concerning Summit and any of its Subsidiaries heretofore furnished to such Person by or on behalf of the Company or any of its Subsidiaries, as applicable. Summit will use reasonable best efforts to promptly terminate all physical and electronic data access previously granted to such Persons.

85

(h)   Definition of Intervening Event. For purposes of this Agreement, “Intervening Event” means a material Effect that was not known and was not reasonably foreseeable to the Summit Board prior to Summit’s execution and delivery of this Agreement (or, if known or foreseeable, the consequences, probability or magnitude of which were not known by the Summit Board as of the date hereof), which Effect, or any consequence thereof (or probability or magnitude of which), occurs, arises or becomes known to the Summit Board after Summit’s execution and delivery of this Agreement and before the Summit Stockholder Approval is obtained; provided that in no event shall any of the following be an Intervening Event or be taken into account in determining whether an Intervening Event has occurred: (a) the receipt, existence or terms of a Summit Acquisition Proposal or a Superior Proposal or any inquiry or communications or matters relating; (b) the fact that Summit and its Subsidiaries meet or exceed (1) any public estimates or expectations for Summit’s revenue, earnings or other financial operations or results for any financial period, or (2) any internal budgets, plans, projections or forecasts of its revenues, earnings or other financial performance or results of operations for any financial period (it being understood that any underlying cause may be taken into account in determining whether there has been an Intervening Event), or (c) any change in the market price or change in the trading volume of Summit Common Stock (it being understood that any underlying cause may be taken into account in determining whether there has been an Intervening Event).

86

membership interests, or otherwise (any of the foregoing, a “Company Acquisition Proposal”), or (ii) enter into or knowingly participate in any discussions or negotiations with, furnish any nonpublic information relating to any ANAC Company or afford access to the business, properties, assets, books or records of any ANAC Company, or otherwise knowingly cooperate with, any Third Party, in each case relating to a Company Acquisition Proposal by such Third Party.

(b)   Prior to Closing, Summit shall not (i) agree to or permit any amendment, supplement or other modification of, or waive any of its rights under, the Debt Commitment Letter, any Debt Financing Agreements or any other definitive agreements or documents related to the Debt Financing or (ii) substitute other debt financing for all or any portion of the Debt Financing from the same or Alternative Financing sources, in each case, without Cementos’s prior written consent (such consent not to be unreasonably withheld, conditioned or delayed), except, solely in the case of the Debt Commitment Letter, any Debt Financing Agreements or any other definitive agreements or documents related to the Debt Financing, to the extent (A) such amendment, supplement, modification or waiver would not (1) reduce the aggregate amount of the Debt Financing (or the cash proceeds available therefrom), when taken together with cash on the balance sheet of Summit and drawings available under Summit’s revolving credit facility, below the amount required to consummate the transactions contemplated by this Agreement, (2) impose new or additional conditions precedent to any of the Debt Financing, or adversely amend, modify or waive any of the existing conditions thereto, (3) be reasonably expected to materially delay the funding of the Debt Financing or satisfaction of the conditions to obtaining the Debt Financing less likely to occur or (4) otherwise reasonably be expected to materially prevent or impair the availability of the amount of the Debt Financing required to consummate the transactions contemplated by this Agreement or the ability of Summit to consummate the transactions contemplated by this Agreement or enforce its rights against the other parties to the Debt Commitment Letter, the Debt Financing Agreements or any other definitive agreements or documents related to the Debt Financing (provided that, subject to compliance with the other provisions of this Section 7.08, Summit may amend the Debt Commitment Letter to add additional lenders, arrangers, bookrunners, managers or agents that have not executed the Debt Commitment Letter as of the date of this Agreement) and (B) with respect to any substitution for other debt financing under clause (ii) above, Summit reasonably determines (after consultation with Cementos) that the terms and conditions of such substitute debt financing, taken as a whole, are more favorable to Summit than the terms and conditions, taken as a whole, contemplated in

95

the Debt Commitment Letter. Upon any such amendment, supplement or modification of the Debt Commitment Letter in accordance with this Section 7.08, Summit shall promptly provide a copy thereof to Cementos, and references to the “Debt Commitment Letter” shall include such documents as permitted to be amended, supplemented or modified under this Section 7.08, and references to the “Debt Financing” shall include the financing contemplated by the Debt Commitment Letter as permitted to be amended, supplemented or modified under this Section 7.08.

If any Alternative Financing is obtained in accordance with this Section 7.08, Summit shall promptly notify Cementos thereof and references to the “Debt Financing,” and “Debt Commitment Letter” (and other like term in this Agreement) shall include such Alternative Financing, as applicable.

For all purposes under this Agreement, in respect of any Straddle Tax Period, the portion of Taxes that are allocable to a Pre-Closing Tax Period will be: (x) in the case of any ad valorem and property Taxes, the amount of such Tax for the entire Straddle Tax Period multiplied by a fraction the numerator of which is the number of days in the Straddle Tax Period ending on and including the Closing Date and the denominator of which is the number of days in the entire Straddle Tax Period, and (y) in the case of any other Taxes, the amount that would be payable if the relevant Straddle Tax Period ended on and included the Closing Date; provided, that the taxable year of any ANAC Company that is a “controlled foreign corporation” (as defined in the Code) shall be deemed to have closed on the Closing Date, including for purposes of computing any inclusion under sections 951 and 951A of the Code (or any corresponding or similar provision of U.S. state or local law). The amount of any item that is taken into account only once for each taxable period (e.g., the benefit of graduated Tax rates, exemption amounts, etc.) shall be allocated between the two portions of the Straddle Tax Period in proportion to the number of days in each portion.

Section 8.05.   Tax Sharing Agreements. All Tax Sharing Agreements between any of the Argos Parties (or any Affiliate of an Argos Party, other than an ANAC Company), on the one hand, and any ANAC Company, on the other hand, shall be terminated as of the Closing Date and, after the Closing Date, no ANAC Company shall be bound thereby or have any liability thereunder.

109

Section 8.06.   Tax Proceedings. Any party that receives written notice of any claim for Taxes or the commencement of any audit, examination, contest, investigation or assessment relating to Taxes of the ANAC Companies (a “Tax Proceeding”) with respect to an Indemnified Tax shall notify such other party within 10 Business Days of receipt of such notice; provided that the failure to provide such notice shall not relieve the Indemnifying Party from any of its obligations under ‎Article 10 except (and only) to the extent the Indemnifying Party suffers an actual prejudice as a result of such failure. Subject to the last sentence of ‎Section 10.03(c), the Argos Parties shall have the right to control the conduct of any Tax Proceeding that relates solely to Indemnified Taxes; provided that (A) the Argos Parties shall: (1) permit Summit to participate in the resolution of such Tax Proceeding and (2) not settle or otherwise compromise such Tax Proceeding without the prior written consent of Summit, which consent shall not be unreasonably withheld, conditioned or delayed; and (B) if the Argos Parties fail to assume control of any such Tax Proceeding after having had reasonable opportunity to do so, Summit may elect to control the handling, disposition and settlement of such proceeding at Argos Party’s expense and the Argos Parties shall pay any Taxes related thereto; provided that Summit shall not settle or otherwise compromise such Tax Proceeding without the prior written consent of the Argos Parties, which consent shall not be unreasonably withheld, conditioned or delayed. Summit shall have the right to control the conduct of all other Tax Proceedings (including any Tax Proceedings related to a Straddle Tax Period); provided that in the event that any Tax Proceeding relates to a Straddle Tax Period and could affect the Tax liability of the Argos Parties or includes Indemnified Taxes, Summit shall: (1) permit the Argos Parties to participate in the resolution of such Tax Proceeding and (2) not settle or otherwise compromise such Tax Proceeding in relation to any Indemnified Tax without the prior written consent of the Argos Parties, which consent shall not be unreasonably withheld, conditioned or delayed.

Section 8.07.   Limitations on Tax Indemnification.

(a)   The Argos Parties shall have no obligation to indemnify Summit to the extent that

(i)   the Indemnified Taxes were taken into account to reduce the Closing Consideration as finally determined pursuant to Article 2 of this Agreement;

(ii)   the Indemnified Tax results from a breach by Summit of any provision of this Agreement; and

(iii)   the Indemnified Tax gives rise to a Tax benefit that is actually realized (determined on a “with and without” basis) by Summit or any of its Affiliates (including, for the avoidance of doubt, the ANAC Companies) as a result of such Indemnified Tax in the year such Indemnified Tax is due.

110

(b)   Except as required by applicable law or with prior written consent of the Argos Parties, on or after the Closing Date, Summit shall not and shall not cause or permit the ANAC Companies or any of its Affiliates to (i) make, change, or revoke any Tax election (including under Sections 336 or 338 of the Code) under applicable Law with respect to any of the ANAC Companies in respect of, or that has retroactive effect to, any taxable period ending on or prior to the Closing Date; (ii) initiate or permit any ANAC Company to initiate any contact with any Taxing Authority regarding any voluntary disclosure or similar procedures involving Taxes for any Pre-Closing Tax Period; (iii) file any ruling or request with any Taxing Authority that relates to Taxes or Tax Returns of any ANAC Company for a Pre-Closing Tax Period; (iv) make or change any Tax election or accounting method that has any effect with respect to any Pre-Closing Tax Period of any ANAC Company; or (v) amend any Tax Return of any ANAC Company for any Pre-Closing Tax Period, except as required by a Governmental Authority, in the cases of each of clauses (i) through (v) above, to the extent such action (or inaction) would reasonably be expected to: (A) increase Taxes for which the Argos Parties would be liable or (B) decrease the amount of any Tax refund to which the Argos Parties are entitled under this Agreement.

Section 8.08.   Tax Refunds.

(a)   Summit shall reimburse the Argos Parties for any Tax refund attributable to any Indemnified Taxes (net of any expenses associated with such refund or Taxes resulting from the receipt thereof) received by Summit or the ANAC Companies after the Closing Date except to the extent of such refund that has otherwise increased the Closing Consideration as finally determined pursuant to Article 2 of this Agreement.

(b)   Summit shall, and shall cause the ANAC Companies to, promptly notify the Argos Parties in writing of the receipt of any Tax refund described in Section 8.08(a).

(c)   Any amount payable to the Argos Parties pursuant to this Section 8.08 shall be due five Business Days after the Tax refund attributable to any Indemnified Taxes has been refunded (including, without limitation, by way of set-off or deduction) to Summit or the ANAC Companies.

Section 8.09.   Purchase Price Allocation. The allocation of the Purchase Price payable to Cementos and the Argos Parties pursuant to this Agreement (the “Purchase Price Allocation”) shall be made in accordance with Schedule V attached hereto, unless otherwise required by a “determination” within the meaning of Section 1313(a) of the Code, and the withholding under Section 2.09, if any is required, shall be made in accordance with such Schedule V.

(a)   Except in the case of Fraud, the representations and warranties of the Parties contained in this Agreement or in any certificate or other writing delivered pursuant hereto or in connection herewith shall not survive the Closing; provided that (i) the Fundamental Representations and any claims made by Summit based on Fraud shall survive the Closing indefinitely or until the latest date permitted by Applicable Law (in each case, giving effect to any waiver or extension of any statutes of limitations), and (ii) solely for purposes of Section

113

10.02(a)(i), (A) the representations and warranties set forth in Section 3.20 shall survive until the six-year anniversary following the Closing, and (B) all other representations and warranties set forth in Article 3 and Article 4, shall survive until the three-year anniversary following the Closing. The covenants and agreements of the Parties contained in this Agreement or in any certificate or other writing delivered pursuant hereto or in connection herewith (x) that require performance in full prior to the Closing shall survive the Closing until the later of (A) the date that is three months after Summit’s filing of its 10-K in respect of the fiscal year ending in which the Closing occurs and (B) the date that is the one year anniversary of the Closing and (y) that are required to be performed, in whole or in part, after the Closing, shall survive the Closing indefinitely or for such shorter period expressly specified therein, except that for such covenants and agreements that survive for such shorter period, breaches thereof shall survive indefinitely or until the latest date permitted by Applicable Law. Any claim for indemnification pursuant to Section 10.02(a)(iv) shall be made no later than the six-year anniversary of the Closing Date.

(b)   Notwithstanding the preceding sentences, any breach of representation, warranty, covenant or agreement, or other indemnity, in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate pursuant to Section 10.01(a) if requisite written notice pursuant to this Article 10 of the breach thereof or Damage giving rise to such right of indemnity shall have been given to Summit (if the indemnity is sought against Summit) or to Cementos (if the indemnity is sought against the Argos Parties), as applicable, prior to such time, or in the case of Fraud. For the avoidance of doubt, in the event notice is delivered to Cementos, such notice will be deemed delivered to each of the Argos Parties.

Section 10.02.   Indemnification. (a) Subject to the limitations set forth in this Article 10, effective at and after the Closing, Cementos and the Argos Parties hereby, jointly and severally, indemnify Summit, each ANAC Company and each of their respective officers, directors, employees, Affiliates and agents and each of their respective successors and permitted assigns (collectively, the “Summit Indemnified Parties”) against and agrees to defend and hold each of them harmless from any and all Damages, incurred or suffered by any Summit Indemnified Party (regardless of whether such Damages arise as a result of the negligence, strict liability, or other liability under any theory of law or equity of any Person and whether involving a Third-Party Claim or claims solely between the Parties) arising out of, relating to or resulting from or under:

(i)   any inaccuracy in or breach of any of the representations and warranties set forth in Article 3 and Article 4 as of the date hereof and as of the Closing Date (except for any such representation and warranty that addresses matters only as of a specific date, which representation and warranty shall be true and correct as of such specific date);

(ii)   any inaccuracy in or breach of any of the Company Fundamental Representation or Argos Party Fundamental Representation as of the date hereof and as of the Closing Date (except for any such representation and warranty that addresses matters only as of a specific date, which representation and warranty shall be true and correct as of such specific date);

114

(iii)   any breach of any covenant or agreement made or to be performed by Cementos, the Argos Parties or the Company pursuant to this Agreement;

(iv)   any Indemnified Tax (to the extent provided in Article 8);

(v)   any Liabilities to the extent relating to the business of Cementos, the Argos Parties and their Affiliates (other than the Business), other than liabilities arising pursuant to the terms of any other Transaction Document (other than this Agreement); and

(vi)   Fraud.

(b)   Except with respect to claims of Fraud, the maximum aggregate amount of indemnifiable Damages that may be recovered from Cementos or any Argos Party pursuant to Section 10.02(a) shall be $3,170,000,000.

(c)   The indemnification provided pursuant to Section 10.02(a)(i) shall be available only to the extent a Summit Indemnified Party incurs Damages in respect of the matters described in Section 10.02(a)(i) and coverage under the R&W Insurance Policy is not available with respect thereto due to either (x) the exhaustion of the Limit of Liability provided under the R&W Insurance Policy, (y) the failure to report such Damages to the insurers under the R&W Insurance Policy prior to the Notice Date provided therein; provided that the failure to report such Damages shall not have been willful and intentional; or (z) both (x) and (y); provided that for purposes of determining the availability of coverage, the impact of the "Retention" in the R&W Insurance Policy shall be disregarded; provided further, that, except in the case of Fraud, the maximum aggregate amount of indemnifiable Damages that may be recovered from Cementos or any Argos Party pursuant to Section 10.02(a)(i) shall be the lesser of (A) the aggregate amount of “Loss” recovered by the Summit Indemnified Parties pursuant to the R&W Insurance Policy in respect of any breach of the representations and warranties contained in Section 3.10 or Section 3.20 or any Indemnified Tax, and (B) $150,000,000. Neither Cementos nor any Argos Party shall be liable in respect for indemnification pursuant to Section 10.02(a)(i) in the circumstances described in clause (y) or (z) of this Section 10.02(c) to the extent the then-applicable "Retention" in the R&W Insurance Policy is greater than zero (in which case the "Retention" shall be deemed to be eroded by the cumulative amount of Damages for which Cementos and the Argos Parties are relieved of liability as a result of this sentence). Capitalized terms used but not defined in this Section II shall have the meanings ascribed to such terms in the R&W Insurance Policy.

(d)   Subject to the limitations set forth in this Article 10, effective at and after the Closing, Summit hereby indemnifies Cementos, each Argos Party and each of their respective officers, directors, employees, Affiliates (other than the ANAC Companies) and agents and each of their respective successors and permitted assigns (collectively, the “Argos Party Indemnified

115

Parties”) against and agrees to defend hold each of them harmless from any and all Damages, incurred or suffered by such Argos Party Indemnified Party (regardless of whether such Damages arise as a result of the negligence, strict liability, or other liability under any theory of law or equity of any Person and whether involving a Third-Party Claim or claims solely between the Parties) arising out of, relating to or resulting from or under:

(i)   any inaccuracy in or breach of any Summit Fundamental Representation as of the date hereof and as of the Closing Date (except for any such representation and warranty that addresses matters only as of a specific date, which representation and warranty shall be true and correct as of such specific date);

(ii)   any breach of any covenant or agreement made or to be performed by Summit pursuant to this Agreement;

(iii)   any Actions asserted by a Third Party to the extent relating to, arising out of or in connection with or resulting from the ownership or the operation of the Business following the Closing except (A) to the extent such Damages are suffered or incurred by such Persons by virtue of their direct or indirect ownership of the Business or (B) with respect to any matters for which Summit is indemnified under this Agreement, including Section 10.02(a), without giving effect to any limitations on such indemnity obligation set forth herein; and

(iv)   Fraud.

(e)   Except with respect to claims of Fraud, the maximum aggregate amount of indemnifiable Damages that may be recovered from Summit arising out of or resulting from the causes enumerated in Sections 10.02(d) shall not exceed $3,170,000,000.

(f)   Notwithstanding anything in this Agreement that may be deemed to be contrary, for purposes of determining the amount of any Damages related to a breach of any representation or warranty contained in this Agreement and for purposes of determining whether there has been a breach of such representation or warranty, the representations and warranties contained in this Agreement shall be considered without regard to any “material,” “Company Material Adverse Effect,” “Summit Material Adverse Effect” or similar qualifications contained therein.

Section 10.03.   Third-Party Claim Procedures. (a) The party seeking indemnification under Section 10.02 (the “Indemnified Party”) agrees to give prompt notice following the first date on which such Indemnified Party has knowledge of facts, matters or circumstances from which it is reasonably apparent that such occurrence is likely to have occurred in writing to the party against whom indemnity is to be sought (the “Indemnifying Party”) of the assertion of any claim or the commencement of any Action (including any Tax audit or administrative or judicial proceeding relating to Taxes) in respect of which indemnity may be sought under Section 10.02 (a “Claim”). Such notice shall set forth in reasonable detail such Claim and the basis for indemnification (taking into account the information then available to the Indemnified Party), including a description of the facts and circumstances giving rise to such occurrences, the

116

estimated amount of Damages imposed, incurred, suffered or asserted in connection therewith or arising therefrom (to the extent then ascertainable), and a description of any other remedy sought in connection therewith (in each case, solely to the extent such information is then available). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have materially and adversely prejudiced the Indemnifying Party.

(b)   The Indemnifying Party shall be entitled to participate in the defense of any Claim asserted by any third party (“Third-Party Claim”) and, subject to the limitations set forth in this Section 10.03, shall be entitled to control and appoint lead counsel for such defense, in each case at its own expense.

(c)   If the Indemnifying Party desires to assume the control of the defense of any Third-Party Claim in accordance with the provisions of this Section 10.03, the Indemnifying Party shall give written notice to the Indemnified Party within 20 days after the Indemnified Party has given written notice to the Indemnifying Party of the Third-Party Claim. If such notice is timely given, the Indemnifying Party shall be entitled to control and appoint lead counsel for such defense so long as (i) the Third-Party Claim involves only a claim for monetary damages and not any claim for an order, injunction or other equitable relief or relief for other than monetary damages against any Indemnified Party, (ii)  the Indemnifying Party timely provides the Indemnified Party with (x) evidence reasonably acceptable to the Indemnified Party that the Indemnifying Party will have adequate financial resources to defend against the Third-Party Claim and fulfill its indemnification obligations hereunder, and (y) a statement that, based on the facts set forth in the notice required by Section 10.03 (assuming that the facts alleged by the third party as set forth in the notice were actually true), the Indemnifying Party would have an indemnity obligation for the Damages resulting from such Third Party Claim, the Third-Party Claim does not relate to or otherwise arise in connection with any criminal or regulatory Action and (iii) the Indemnifying Party is reasonably diligently defending or prosecuting the Third-Party Claim.

(d)   If the Indemnifying Party is controlling the defense of a Third-Party Claim, the Indemnifying Party shall obtain the prior written consent of the Indemnified Party before entering into any settlement, compromise or discharge of such Third-Party Claim; provided that (i) the Indemnified Party’s consent shall not be unreasonably withheld, conditioned or delayed and (ii) the prior written consent of the Indemnified Party shall not be required if the settlement, compromise or discharge, by its express terms, (i) obligates the Indemnifying Party to pay the full amount of the Damages in connection with such Third-Party Claim and the Indemnifying Party has the financial ability to pay the full amount of such Damages, (ii) is for money damages only and does not impose injunctive or equitable relief or require an admission or finding of liability or wrongdoing and (iii) contains a full and unconditional release of all Indemnified Parties and their Affiliates from all Damages and obligations with respect to such Third-Party Claim.

(e)   If the Indemnifying Party does not timely deliver the notice contemplated by Section 10.03(b), or if such notice is given on a timely basis but any of the other conditions in this Section 10.03 are unsatisfied, the Indemnified Party may defend the Third-Party Claim, but shall be required to obtain the prior written consent of the Indemnifying Party before entering into any settlement, compromise or discharge of such Third-Party Claim, provided that the Indemnifying Party’s consent shall not be unreasonably withheld, conditioned or delayed.

117

(f)   In circumstances where the Indemnifying Party is controlling the defense of a Third-Party Claim, the Indemnified Party shall be entitled to participate in the defense of any Third-Party Claim and to employ separate counsel of its choice for such purpose, in which case the fees and expenses of such separate counsel incurred by the Indemnified Party after such time as the Indemnifying Party assumed control pursuant to Section 10.03(b) shall be borne by the Indemnified Party; provided that notwithstanding the foregoing, the Indemnifying Party shall pay the fees and expenses of such separate counsel (i) incurred by the Indemnified Party prior to the date the Indemnifying Party assumes control of the defense of the Third-Party Claim or during any period in which the Indemnifying Party ceases to be eligible to maintain control of the defense of the Third-Party Claim, in either case as provided in this Section 10.03, (ii) if representation of both the Indemnifying Party and the Indemnified Party by the same counsel would create a conflict of interest (including if any counsel chosen by the Indemnifying Party requests a conflict wavier or other waiver from the Indemnified Party with respect to such matter) or (iii) there may be one or more defenses or claims available to the Indemnified Party that are different from or additional to those available to the Indemnifying Party and that could be adverse to the Indemnifying Party.

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

(h)   Notwithstanding the foregoing provisions of this Section 10.03, with respect to any Tax Proceeding, the procedures set forth in the applicable provisions of Article 8 shall apply.

Section 10.04.   Direct Claim Procedures. In the event an Indemnified Party has a claim for indemnity under Section 10.02 against an Indemnifying Party that does not involve a Third-Party Claim, the Indemnified Party agrees to give prompt notice in writing of such claim to the Indemnifying Party. Such notice shall set forth in reasonable detail such claim and the basis for indemnification (taking into account the information then available to the Indemnified Party), including a description of the facts and circumstances giving rise to such occurrences, the estimated amount of Damages imposed, incurred, suffered or asserted in connection therewith or arising therefrom (to the extent then ascertainable), and a description of any other remedy sought in connection therewith (in each case, solely to the extent such information is then available). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have materially and adversely prejudiced the Indemnifying Party. The Indemnifying Party shall have a period of 30 days within which to respond to such Claim. If the Indemnifying Party has timely disputed its indemnity

118

obligation for any Damages with respect to such claim, the parties shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in an appropriate court of jurisdiction determined pursuant to Section 12.06. If the Indemnifying Party does not object in writing to such claim within such 30 days after receipt of written notice from the Indemnified Party, such failure shall constitute an irrevocable acknowledgement by the Indemnified Party that the Indemnified Party is entitled to the full amount of the claims for Damages set forth in such notice.

Section 10.05.   Calculation of Damages. (a) The amount of any Damages payable under this Article 10 by the Indemnifying Party shall be net of any amounts recovered by the Indemnified Party under insurance policies (including the R&W Insurance Policy), net of any costs or expenses incurred in the collection thereof, including deductibles, indemnity, reimbursement arrangements or other similar arrangements (each, an “Alternative Recovery”). Solely with respect to claims for Damages arising under Sections 10.02(a)(iii) or 10.02(a)(iv), the Summit Indemnified Party shall use its commercially reasonable efforts to seek recovery under the R&W Insurance Policy, to the extent coverage would reasonably be expected to be available thereunder (assuming all other past, current and future claims are paid out in full by the insurers thereunder), and if Summit receives insurance proceeds after having received payment from an Indemnifying Party pursuant to this Article 10 in respect thereof, then to the extent such insurance proceeds were not taken into account in determining the amount of Damages required to be paid by the applicable Indemnifying Party to Summit with respect thereto, Summit shall refund to the applicable Indemnifying Party up to the lesser of (x) the amount of such insurance proceeds so received, and (y) the amount of the indemnification payment received by the Summit Indemnified Party from the Indemnifying Party with respect thereto pursuant to this Article 10, in each case, after deducting therefrom the amount of any costs or expenses incurred in procuring such recovery, net of any Taxes actually imposed on the Summit Indemnified Party that arise from having received amounts under the R&W Insurance Policy (such Taxes being reduced by any refund, offset in Tax or other Tax Asset realized by Summit or its Affiliates from the payment of amounts under this Section 10.05); provided that, (A) the amount the Summit Indemnified Party is required to refund pursuant to this sentence shall not exceed the amount by which the indemnification payment actually paid to the Summit Indemnified Party in respect of such Damages pursuant to this Article 10 would have been reduced pursuant to this Section 10.05 had such recovery been received prior to the date of such indemnification payment, and (B) notwithstanding the foregoing, any Summit Indemnified Party may deliver a Claim against Cementos or any Argos Party at any time in order to reserve rights under this Article 10.

(b)   Each Argos Party hereby agrees that (i) the availability of indemnification of the Summit Indemnified Parties under this Article 10 shall be determined without regard to any right to indemnification, advancement, contribution or reimbursement that such Argos Party may have from any ANAC Company (whether such rights may arise from or pursuant to Applicable Law, Contract, the Governing Documents of any ANAC Company or otherwise), and (ii) such Argos Party shall not be entitled to any indemnification, advancement, contribution or reimbursement from Summit, any ANAC Company or any of their respective Affiliates for amounts for which Summit Indemnified Parties would be entitled to indemnification under this Article 10 (determined without regard to any thresholds, baskets, deductibles, caps, survival periods or other limitations).

119

Section 10.06.   Characterization of Indemnification Payments. To the extent permitted by Applicable Law, any amount paid pursuant to this Article 10 shall be treated for Tax purposes as adjustments to the Closing Consideration.

Section 10.07.   Mitigation. Each Indemnified Party shall use its reasonable best efforts to mitigate any indemnifiable Damages to the extent required by Applicable Law; provided that the costs to mitigate shall be deemed to be indemnifiable Damages.

Section 10.08.   Exclusivity of Remedy.

(a)   Without limiting any Party’s rights (w) pursuant to Section 7.21, (x) under any other Transaction Document or any other agreement entered into in connection with this Agreement, (y) with respect to claims for Fraud or (z) disputes under Section 2.06 (which disputes will be resolved in accordance with the dispute resolution provisions set forth in Section 2.06), the Parties acknowledge and agree that, from and after the Closing, the indemnification provisions in this Article 10 shall be the sole and exclusive monetary remedy of any Party with respect to any and all claims arising out of breaches of representations, warranties, covenants or agreements contained in this Agreement. For the avoidance of doubt, (b) nothing herein is intended to, nor shall it have the effect of, limiting or diminishing Summit Indemnified Parties’ right to seek or obtain recovery under the R&W Insurance Policy, and (c) as between Summit, on the one hand, and the insurers of the R&W Insurance Policy, on the other hand, none of the limitations and restrictions on indemnification set forth in this Article 10 shall affect the rights of Summit under the R&W Insurance Policy, which rights shall be governed solely thereby.

(b)   This Agreement may only be enforced against, and any Action, right or remedy that may be based upon, arise out of or relate to this Agreement, any other Transaction Document or the Transactions, or the negotiation, execution or performance of this Agreement, may only be made against the Persons that are expressly identified as Parties in their capacities as parties to this Agreement, and no Party shall at any time assert against any Person (other than a Party) which is a director, officer, employee, shareholder, general or limited partner, member, manager, agent or Affiliate or Representative of another Party (each, a “Nonparty”), any claim, cause of action, right or remedy, or any Action, relating to this Agreement, any other Transaction Document, the Transactions or any document or instrument delivered in connection herewith or therewith. Each Party hereby waives and discharges any such claim, cause of action, right, remedy and Action, and releases (and agrees to execute and deliver any instrument necessary to effectuate the release of) each Nonparty therefrom.

Section 11.03.   Summit Termination Fees.

(a)   If this Agreement is validly terminated by Summit pursuant to ‎Section 11.01(d)(i) (Superior Proposal) to enter into a written definitive agreement with a Third Party or by Cementos pursuant to ‎Section 11.01(c)(i) (Adverse Recommendation Change), Summit shall pay or cause to be paid to Cementos in immediately available funds an amount equal to the Summit Termination Fee, in the case of a termination by Cementos, within two Business Days after such termination and, in the case of a termination by Summit, before or contemporaneously with such termination.

(b)   If, prior to receipt of the Summit Stockholder Approval, (A) this Agreement is terminated by Cementos pursuant to Section 11.01(c)(ii) (Material Breach) or ‎by Cementos or Summit pursuant to Section 11.01(b)(i) (End Date), ‎‎Section 11.01(b)(iii) (Company No Vote), (B) after the date of this Agreement and prior to the date of termination (in the case of a termination pursuant to ‎‎Section 11.01(b)(i) (End Date) or Section 11.01(c)(ii) (Material Breach)) or the date of the Summit Stockholders Meeting (in the case of a termination pursuant to Section 11.01(b)(iii) (Company No Vote)), a Summit Acquisition Proposal shall have been publicly announced and not withdrawn prior to the date of termination (in the case of a termination pursuant to ‎‎Section 11.01(b)(i) (End Date) or Section 11.01(c)(ii) (Material Breach)) or the date of the Summit Stockholders Meeting (in the case of a termination pursuant to‎‎ Section 11.01(b)(iii) (Company No Vote)) and (C) within 12 months after the date of such termination, (1) Summit enters into a definitive agreement with respect to a Summit Acquisition Proposal or (2) a Summit Acquisition Proposal is subsequently consummated (provided that for purposes of this Section 11.03(b), each reference to “20%” in the definition of Summit Acquisition Proposal shall be deemed to be a reference to “70%”), then Summit shall pay to Cementos in immediately available funds, concurrently with the occurrence of either of the events described in the foregoing clauses (C)(1) or (C)(2).

(c)   Each Party agrees that (i) the agreements contained in this ‎Section 11.03 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, the other parties would not enter into this Agreement and (ii) in light of the difficulty of accurately determining actual damages with respect to the foregoing, the right to payment of the Summit Termination Fee constitutes a reasonable estimate of the losses, damages, claims, costs or expenses that will be suffered by reason of any such termination of this Agreement and constitutes liquidated damages (and not a penalty) and hereby irrevocably waives, and agrees not to assert in any Action arising out of or relating to this Agreement, any claim to the contrary.

123

(d)   Notwithstanding anything herein to the contrary, Cementos and the Argos Parties, on their own behalf and on behalf of their respective Related Parties, agree that, upon any termination of this Agreement under circumstances where the Summit Termination Fee is payable by Summit pursuant to this Section 11.03 and such Summit Termination Fee is paid in full, the receipt by Cementos of the Summit Termination Fee shall be deemed to be liquidated damages and the sole and exclusive monetary remedy of Cementos (other than any willful and intentional breach of Section 6.04(a)), the Argos Parties and their respective Related Parties, in connection with this Agreement or the Transactions and neither Cementos nor any Argos Party (nor any other Person) shall seek to obtain any recovery, judgment, or damages of any kind, including consequential, indirect, or punitive damages, against Summit or any of Summit’s Subsidiaries or any of their respective directors, officers, employees, partners, managers, members, stockholders, Affiliates or Representatives or any Debt Financing Party in connection with this Agreement or the Transactions, including any breach of this Agreement (other than any willful and intentional breach of Section 6.04(a)) (provided that, in the event of any Action among the Parties with respect to an alleged willful and intentional breach of Section 6.04(a), the non-prevailing Party shall pay the reasonable attorneys’ fees and other costs and expenses (including expert witness fees) of the prevailing Party in such amount as the may be determined). Each Party acknowledges and agrees that in no event shall Summit be required to pay the Summit Termination Fee on more than one occasion.

(e)   If Summit fails to promptly pay any amount due pursuant to this Section 11.03 and, in order to obtain such payment, Cementos commences an Action that results in a judgment against Summit for such amount or any portion thereof, Summit shall pay to Cementos its reasonable out-of-pocket fees, costs and expenses (including reasonable attorneys’ fees) in connection with such Action, together with interest on such amount due or portion thereof at the annual rate of 5% plus the prime rate as published in the Wall Street Journal in effect on the date that such payment or portion thereof was required to be made through the date that such payment or portion thereof was actually received, or a lesser rate that is the maximum permitted by Applicable Law.

(f)   While Cementos may pursue both a grant of specific performance in accordance with Section 12.11 and the payment of the Summit Termination Fee, as applicable, under Section 11.03, under no circumstances shall Cementos be permitted or entitled to receive both a grant of specific performance that results in the Closing and any money damages, including all or any portion of the Summit Termination Fee.

130

with such matters. Accordingly, each of Summit and the Company hereby (i) waives and shall not assert, and agrees after the Closing to cause its Subsidiaries to waive and to not assert, any conflict of interest arising out of or relating to the representation by one or more Prior Company Counsel of one or more Designated Persons in connection with one or more Post-Closing Matters (the “Post-Closing Representation”) and (ii) agrees that, in the event that a Post-Closing Matter arises, Prior Company Counsel may represent one or more Designated Persons in such Post-Closing Matter even though the interests of such Person(s) may be directly adverse to Summit or any of its Subsidiaries (including the Company and its Subsidiaries), and even though Prior Company Counsel may (A) have represented the Company or its Subsidiaries in a matter substantially related to such dispute or (B) be currently representing the Company or any of its Subsidiaries. Without limiting the foregoing, each of Summit and the Company (on behalf of itself and its Subsidiaries) consents to the disclosure by Prior Company Counsel, in connection with one or more Post-Closing Representations, to the Designated Persons of any information substantially related to such Post-Closing Representations learned by Prior Company Counsel in the course of one or more Existing Representations, whether or not such information is subject to the attorney-client privilege of the Company or any of its Subsidiaries or Prior Company Counsel’s duty of confidentiality as to the Company or any of its Subsidiaries and whether or not such disclosure is made before or after the Closing.

(b)   Attorney-Client Privilege. Each of Summit and the Company (on behalf of itself and its Subsidiaries) waives and shall not assert, and agrees after the Closing to cause its Subsidiaries to waive and to not assert, any attorney-client privilege, attorney work-product protection or expectation of client confidence with respect to any confidential or privileged communication between any Prior Company Counsel, on the one hand, and any Designated Person or the Company or any of its Subsidiaries, on the other hand (collectively, the “Pre-Closing Designated Persons”), or any legal advice given to any Pre-Closing Designated Person by any Prior Company Counsel, in each case to the extent occurring during one or more Existing Representations (collectively, “Pre-Closing Privileges”) in connection with any Post-Closing Representation, including in connection with a dispute between any Designated Person and one or more of Summit, the Company and their respective Subsidiaries, it being the intention of the Parties hereto that all rights to such Pre-Closing Privileges, and all rights to waive or otherwise control such Pre-Closing Privilege, shall be retained by Cementos and the Argos Parties, and shall not pass to or be claimed or used by Summit or the Company, except as provided in the last sentence of this Section 12.18(b). Furthermore, each of Summit and the Company (on behalf of itself and its Subsidiaries) acknowledges and agrees that any advice given to or communication with any of the Designated Persons to the extent related to an Existing Representation or a Post-Closing Representation shall not be subject to any joint privilege (whether or not the Company or one or more of its Subsidiaries also received such advice or communication) and shall be owned solely by such Designated Persons. Notwithstanding the foregoing, in the event that a dispute arises between Summit or the Company or any of its Subsidiaries, on the one hand, and a third party other than a Designated Person, on the other hand, the Company shall (and shall cause its Subsidiaries to) assert to the extent available the Pre-Closing Privileges on behalf of the Designated Persons (and at such Designated Person’s sole cost and expense) to prevent disclosure of Privileged Materials to such third party; provided, however, that such privilege may be waived only with the prior written consent of Cementos (on behalf of the Argos Parties), which consent shall not be unreasonably conditioned, withheld or delayed.

132

(c)   Privileged Materials. All such Pre-Closing Privileges, and all books and records and other documents of the Company and its Subsidiaries to the extent containing any advice or communication that is subject to any Pre-Closing Privilege (“Privileged Materials”), shall be deemed excluded from the acquisition of the Purchased Shares, and shall be distributed to Cementos (on behalf of the applicable Designated Persons) immediately prior to the Closing with (in the case of such books and records solely to the extent containing any Privileged Materials) no copies retained by the Company or any of its Subsidiaries. Absent the prior written consent of Cementos (on behalf of the Argos Parties) (which consent shall not be unreasonably conditioned, withheld or delayed), none of Summit or (following the Closing) the Company shall have a right of access to Privileged Materials. The Company shall deliver all Privileged Materials to Cementos (on behalf of the applicable Designated Persons) within a reasonable period of time following the Closing.
