Notwithstanding anything to the contrary contained in Section 1.01(a), the Sellers shall not be required to assign to the Purchaser at the Closing any Nontransferable Contracts (or any rights related thereto, including to any Software) if the assignment or attempted assignment thereof would result in a breach or violation of, or default under, the terms thereof (any such Nontransferable Contracts being

-8-

hereinafter referred to as “Retained Contracts”). Each of the Sellers, the Parent and the Purchaser agrees that from and after the Closing Date it will take, or cause to be taken, all reasonable actions necessary to obtain as promptly as practicable any required consent, approval or authorization to the assignment or other transfer of the Retained Contracts to the Purchaser. If and so long as any required consent, approval or authorization to the assignment or other transfer of any Retained Contracts to the Purchaser shall not have been obtained, the parties shall establish an agency-type relationship or other similar arrangement reasonably satisfactory to the Sellers and the Purchaser under which (i) the Purchaser is provided with such rights and benefits under such Retained Contracts as will not result in a violation or breach of, or constitute a default under, applicable Law or the terms of such Retained Contracts, including enforcement by the Sellers for the account of the Purchaser of any and all rights and benefits of the Sellers under such Retained Contracts, and (ii) as between the Purchaser and the Sellers, the Purchaser shall assume all obligations of the Sellers under such Retained Contracts, and all liabilities for the failure to perform such obligations, to the extent such obligations relate to and are required to be performed during periods after the Closing, and without limiting the generality of the foregoing, the Purchaser will (A) be responsible, as a subcontractor or service provider to the Sellers, for the completion of any work or provision of any goods or services thereunder to be performed or provided after the Closing, (B) bear all Taxes (if any) imposed or levied solely with respect thereto or arising therefrom and (C) be responsible for any breach of warranty for goods or services provided by the Purchaser thereunder or any related repurchase, indemnity or service obligations owed to the third-party contract party under any such Retained Contract arising out of Purchaser’s performance thereof. Notwithstanding anything to the contrary contained in this Agreement, if, as a condition to the assignment of any Retained Contract, the counterparty thereto requests a parent guaranty by the Parent of the obligations that would be assumed by the Purchaser and the Parent refuses to provide such guaranty, then the applicable Seller may, after sixty (60) days following the later of (i) the Closing Date or (ii) the date upon which the counterparty requests a parent guaranty, terminate such Retained Contract if and to the extent permitted under the terms thereof (without the payment of any penalty or termination fee). The Sellers shall not be required to exercise any options to extend or renew the term of any Retained Contracts.

SECTION 1.04. Purchase Price.

The consideration to be paid by the Purchaser to the Sellers in consideration of the sale, conveyance, assignment, transfer and delivery of the Assets shall be (a) cash in the amount of $445,600,000 (the “Base Price”), as adjusted pursuant to Section 1.05 (the “Purchase Price”) plus (b) the assumption by the Purchaser of the Assumed Liabilities.

SECTION 1.05. Working Capital Adjustment.

(a) The following preliminary adjustment to the Purchase Price in respect of Net Working Capital shall be made at the Closing:

(i) No later than three (3) Business Days prior to the Closing Date, Lafarge shall prepare and deliver to the Parent a certificate of the Chief Financial Officer of Lafarge (the “Initial CFO Certificate”) setting forth an estimated calculation of the Net

-9-

Working Capital as of the Closing Date prepared in accordance with the Working Capital Principles (“Estimated Working Capital”), together with reasonable supporting documentation. Thereafter, at the request of the Parent, Lafarge shall give the Parent reasonable access during normal business hours to the Books and Records and any other books and records of the Sellers that relate to the Business that are relevant to the calculation of the Estimated Working Capital. In addition, the Sellers shall make representatives of the Sellers reasonably available to answer questions with respect to the calculation of the Estimated Working Capital. The Sellers and the Parent shall cooperate in good faith and endeavor to resolve any disputes regarding the calculation of the Estimated Working Capital. If the parties agree to any changes to the Estimated Working Capital, the term “Estimated Working Capital” as used in this Agreement shall be deemed to reflect such changes.

(ii) At the Closing, (A) if Estimated Working Capital is less than $31,500,000, then an amount equal to the difference between the Estimated Working Capital and $31,500,000 shall be subtracted from the Base Price and (B) if Estimated Working Capital is greater than $31,500,000, then an amount equal to the difference between $31,500,000 and the Estimated Working Capital shall be added to the Base Price.

(b) The following final adjustment to the Purchase Price in respect of Net Working Capital shall be made after the Closing:

(i) No later than ninety (90) days after the Closing Date, the Parent shall prepare and deliver to Lafarge a certificate of the Chief Financial Officer of the Parent (the “Final CFO Certificate”) setting forth a proposed calculation of Net Working Capital for purposes of the final adjustment contemplated by this Section 1.05(b) (“Final Working Capital”) prepared in accordance with the Working Capital Principles, together with reasonable supporting documentation. Thereafter, at the request of either Lafarge or the Parent, the other party shall give Lafarge or the Parent (as the case may be) access during normal business hours to the Books and Records and the other books and records of the Sellers relating to the Business that are relevant to the calculation of Final Working Capital (it being understood that the obligations of Lafarge pursuant to this sentence shall be limited to providing access to any books and records retained by it pursuant to this Agreement or the Transition Services Agreement). In addition, the Parent shall make its representatives reasonably available to answer questions with respect to the calculation of the Final Working Capital.

(ii) Lafarge shall be entitled to dispute the calculation of the Final Working Capital set forth in the Final CFO Certificate if it delivers a written notice (an “Objection Notice”) to the Parent within sixty (60) days after delivery of the Final CFO Certificate (the “Objection Period”) in which it objects to the calculation by the Parent of the Final Working Capital. The Objection Notice shall contain a reasonably detailed description of any changes that Lafarge proposes to be made to the calculation of Final Working Capital set forth in the CFO Certificate. If Lafarge does not deliver an Objection Notice to the Parent within the Objection Period, Lafarge shall not be entitled to dispute the calculation of Final Working Capital set forth in the Final CFO Certificate, which shall be final and binding on each of the parties.

-10-

(iii) If Lafarge delivers an Objection Notice to the Parent within the Objection Period, the Parent and Lafarge shall attempt in good faith to agree upon the amount of the Final Working Capital during the period commencing on the date of delivery of the Objection Notice and ending 30 days thereafter (the “Negotiation Period”). If the Parent and Lafarge agree in writing on the Final Working Capital (whether such amounts are the same as or different from the amounts set forth in the Final CFO Certificate) during the Negotiation Period, the Final Working Capital shall be the amounts agreed upon by the parties.

(iv) If the Parent and Lafarge do not agree in writing on the Final Working Capital prior to the expiration of the Negotiation Period, each party shall submit to the other, not later than ten days after the end of the Negotiation Period, a statement containing its calculation of the items in dispute (each, an “Arbiter Statement”), which shall include only those items set forth in the Objection Notice that remain in dispute at the expiration of the Negotiation Period, to KPMG LLP or, if such firm declines to serve as accounting arbiter or the parties agree in writing not to engage such firm, such other firm of independent public accountants mutually agreed upon by the Parent and Lafarge (in either case, the “Accounting Arbiter”), which firm shall make a final and binding determination as to all matters in dispute as promptly as practicable after its appointment. In determining the proper amount of the Final Working Capital, the Accounting Arbiter shall be bound by the terms of this Section 1.05 and may not increase the amount of any item in dispute above the highest amount set forth in the Arbiter Statements nor decrease any such amount below the lowest amount set forth in the Arbiter Statements. The Accounting Arbiter shall send its written determination of the Final Working Capital, to the Parent and Lafarge, and such determination and calculation shall be final and binding on the parties, absent fraud or manifest error. The fees and expenses of the Accounting Arbiter shall be borne by Lafarge and the Parent in inverse proportion to the dollar amount of the items in dispute set forth in the Arbiter Statements as to which such party prevails in the accounting arbitration, which proportionate allocations shall also be determined by the Accounting Arbiter at the time it renders its determination on the merits of the matters in dispute. The Accounting Arbiter may not award damages, interest or penalties to any party with respect to any matter.

(v) No later than five (5) days after a final and binding determination of the Final Working Capital has been made in accordance with the applicable provisions of this Section 1.05(b), (A) if the Purchase Price is greater than the Base Price, as adjusted pursuant to Section 1.05(a), then the Purchaser shall make a payment equal to such difference in immediately available funds to such account or accounts as is designated in writing by Lafarge (it being agreed that Lafarge shall be entitled to direct that such payment be divided between Lafarge, on the one hand, and the other Sellers, on the other hand) or (B) if the Base Price, as adjusted pursuant to Section 1.05(a), is less than the Purchase Price, then Lafarge and the Sellers shall make payments in an aggregate amount (to be divided between Lafarge, on the one hand, and the other Sellers, on the other hand, in such proportions as Lafarge shall direct) equal to such difference in immediately available funds to such account or accounts as is designated in writing by the Parent.

SECTION 1.06. Purchase Price Allocation.

(a) The parties agree that the Purchase Price (adjusted to reflect the “purchase price” for U.S. federal, state and local tax purposes) shall be allocated among the Assets and among the Sellers in accordance with an allocation prepared in compliance with Section 1060 of the Code and the Treasury regulations promulgated thereunder (the “Allocation”). No later than 90 days after the Closing Date, the Parent shall deliver a proposed Allocation to Lafarge, prepared in good faith and in accordance with applicable Law. Thereafter, at the request of Lafarge, the Parent shall give Lafarge reasonable access during normal business hours to the books and records of the Business relevant to the Allocation. In addition, representatives of the Parent will be reasonably available to answer questions with respect to the Allocation.

(b) If Lafarge has any objections to the proposed Allocation, Lafarge shall notify the Purchaser in writing of such objections (the “Allocation Objections”) no later than forty-five (45) days after delivery of the proposed Allocation. The Allocation Objections, if any, shall set forth in reasonable detail the basis for any disagreement with the proposed Allocation prepared by the Parent. If Lafarge does not deliver Allocation Objections to the Parent by the date specified above, the proposed Allocation delivered by the Parent to Lafarge shall be final and binding on each of the parties.

(c) Upon delivery of the Allocation Objections, the Parent and Lafarge shall use commercially reasonable efforts to resolve all items in dispute with respect to the Allocation. Without limiting the generality of the foregoing, upon delivery of the Allocation Objections, each of the Parent and Lafarge shall promptly (but in no event later than five days after delivery of such objections) designate a senior financial officer of such party to participate in discussions regarding the Allocation with a senior financial officer of the other party. Thereafter, the Parent and Lafarge shall cause the senior financial officers designated by them to meet one or more times (as necessary under the circumstances) to resolve any differences between the parties with respect to the Allocation Objections. If the Parent and Lafarge agree in writing upon the items in dispute within forty (40) days after delivery of the Allocation Objections, the agreement reached by the parties as to the Allocation shall be final and binding on the parties. If the Parent and Lafarge are unable to resolve all items in dispute within forty (40) days after delivery of the Allocation Objections, each party shall be permitted to adopt its own position with regard to the Allocation, and neither party shall have any further obligations to the other with respect to the Allocation of the Purchase Price among the Assets for Tax purposes.

(d) If the Allocation (as revised by agreement of the parties, if applicable) becomes final and binding in accordance with the provisions of Section 1.06(b) or Section 1.06(c) (the “Final Allocation”), then (i) the parties shall follow the Final Allocation for all relevant Tax purposes (including the filing of any Tax Return), (ii) any subsequent

-12-

adjustments to the “purchase price” (as determined for U.S. federal, state or local law purposes, including to reflect the Final Working Capital determined pursuant to Section 1.05) shall be reflected in the Final Allocation in a manner consistent with Section 1060 of the Code and the Treasury regulations promulgated thereunder, (iii) the transactions contemplated in this Agreement shall be reported in a manner consistent with the Final Allocation, and none of the parties shall, except as required pursuant to a “determination” within the meaning of Section 1313(a) of the Code (or any comparable provision of any state or local law), take any position inconsistent therewith in any Tax Return, in any refund claim, in any Legal Proceeding, or otherwise, and (iv) the Sellers, on the one hand, and the Purchaser and the Parent, on the other hand, (A) shall prepare mutually acceptable and substantially identical IRS Forms 8594 (and other similar Tax Returns), (B) shall furnish the other with a copy of such forms within a reasonable period before its filing due date, (C) shall notify each other and cooperate in case of an audit or other investigation or dispute with respect to the Final Allocation or the treatment provided in Section 8.04(c), and (D) shall cooperate and provide the others promptly with any other information required to complete Form 8594 or any other applicable Tax Return.

SECTION 1.07. Receivables Settlement.

Within thirty (30) days after the determination of Final Working Capital in accordance with the provisions of Section 1.05(b) (or, if such determination is not made within 180 days after the Closing, within five (5) days after such determination is made), the Parent shall deliver a written notice to Lafarge (a) identifying any Receivables included in the Final Working Capital that (i) as of the Closing Date, were aged (180) days or more from the due date and (ii) the Parent elects in its sole discretion to require the Sellers to repurchase in accordance with the terms of this Section 1.07 (such trade account receivables being hereinafter referred to as the “Repurchased Receivables”) and (b) certifying that the Parent and the Purchaser used reasonable best efforts to collect the Repurchased Receivable during the period from and after the Closing until delivery of such notice. Within thirty (30) days after delivery of such notice to Lafarge, (i) the Purchaser shall transfer to Lafarge, and Lafarge shall acquire and accept from the Purchaser, the Repurchased Receivables and (ii) Lafarge shall pay to the Purchaser an amount in cash equal to the excess, if any, of (a) the aggregate amount of the Repurchased Receivables, less any amount previously collected in respect thereof by the Purchaser from the obligor thereon, over (b) the reserve or allowance applicable to such Receivables in the calculation of Final Working Capital.

(b) Without limiting the generality of Section 5.02(a), during the period from and after the date of this Agreement through the Closing Date, the Sellers shall reasonably cooperate with the Parent and the Purchaser and their respective attorneys, accountants and other advisors and representatives in connection with their due diligence review of the Real Property included in the Assets, and the Sellers shall (i) provide access to the Facilities, upon reasonable prior notice and during normal business hours, to the surveyor hired by the Purchaser to, at the Purchaser’s expense, survey such Facilities in connection with obtaining Title Policies, (ii) provide to the Purchaser all documents and information in their possession (or reasonably accessible to either the Sellers or the Title Company) relating to title to or the leasehold interests in such Real Property, and any exceptions to or defects in such title or leasehold interests, (iii) use its commercially reasonable efforts to

cooperate with the Purchaser and the Title Company in connection with the compilation, review and examination of title to the Real Property and in connection with obtaining the Title Policies, including by providing customary affidavits and other similar instruments as are reasonably required by the Title Company for the deletion of any standard or printed exceptions in the Title Policies that are customarily deleted by virtue of a seller delivering such instruments in commercial real estate transactions in the state in which the Real Property which is the subject of such Title Policy is located and (iv) use commercially reasonable efforts to cooperate with the Purchaser in obtaining new surveys (any such new surveys to be obtained at Purchaser’s option and expense).

For the avoidance of doubt, the obligation to pay transfer taxes, deed taxes, lease taxes, or stamp or similar charges relating to the conveyance of the Real Property are allocated as part of “transfer Taxes” in Section 5.08(a) and Section 5.08(b).

(c) In accessing the Real Property, the Purchaser shall at all times comply with all applicable Laws, and the Purchaser shall not, and shall cause its employees, agents, contractors and other representatives not to, (i) interfere in any material respect with the operation of the Assets or the conduct of the Business or with any other business of a Seller or, if applicable, the business of any of the tenants of such Seller conducted at the Real Property, or disturb in any material respect the use or occupancy of a Seller or any of its tenants; or (ii) damage the Real Property. The Purchaser shall schedule and coordinate all access with the Seller Representative and shall give such Seller at least one (1) Business Day written notice prior to accessing the Real Property. The Sellers shall be entitled to have a representative present at all times when the Purchaser is exercising its rights to access hereunder. The Purchaser agrees to pay to the applicable Seller within twenty (20) Business Days of each Seller’s written request the actual cost of repairing and restoring any damage which the Purchaser or any of its employees, agents, contractors or other representatives shall cause to the Real Property or any property of a Seller or any of a Seller’s employees, agents, contractors or representatives located thereon prior to the Closing.

correspondence and other documents in the possession of, or reasonably available to the Sellers regarding the environmental condition of the Assets, or the compliance (or noncompliance) of the Assets and the Business as it relates to the Assets, with any Environmental Laws that were not provided to the Seller prior to the date of this Agreement.

The interest of the Sellers in and to any Installed Software that is transferrable without the consent of a third party (if any) and any Installed Software with respect to which consents to transfer are obtained by the Purchaser shall be transferred by the Sellers to the Purchaser at the Closing. Notwithstanding anything to the contrary in this Agreement, the Sellers make no representations or warranties with respect to the Installed Software that may be transferred pursuant to this Section 5.03(d).

SECTION 5.04. Parent Financing.

(a) During the period commencing on the date of this Agreement and ending on the Closing Date, the Parent shall use its reasonable best efforts to take, and cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable so that there will be on the Closing Date revolving credit commitments in an amount at least equal to the Minimum Available Credit available to be drawn under the Parent Credit Facility for the purpose of funding the payment of a portion of the Purchase Price to the Sellers. Without limiting the generality of the foregoing, the Parent shall not agree to any amendment, supplement or other modification of, or waive any of its rights under, the Parent Credit Facility if such amendment, supplement, modification or waiver would reasonably be expected to (i) reduce the aggregate amount of the revolving credit commitments that are available on the Closing to be drawn for the purpose of funding the payment of a portion of the Purchase Price to an amount less than the Minimum Available Credit or (ii) modify the conditions to the making of borrowings under the Parent Credit Facility in a manner that could reasonably be expected to prevent or delay the Closing.

(b) The Sellers hereby acknowledge that the Parent has advised them that, in order to obtain a portion of the funding required for the payment of the Purchase Price pursuant to this Agreement, the Parent will need to complete (i) a successful Parent Equity Offering, and realize net proceeds therefrom in an aggregate amount equal to at least $125 million or (ii) complete one or more successful Other Parent Offerings, it being expressly agreed and acknowledged by each of the parties that the obligations of the Parent and the Purchaser to consummate the transactions contemplated in the Agreement shall not be subject to the success of the Parent Equity Offering or any Other Parent Offerings or to the availability of the Minimum Available Credit.

-49-

(c) The Sellers shall provide such assistance and cooperation to the Parent as it may reasonably request in connection with the Parent’s efforts to consummate any Parent Equity Offering or Other Parent Offering to be carried out prior to the Closing (each, a “Parent Offering”), including (i) participating in a reasonable number of customary due diligence or drafting sessions with the Parent and its lenders party to the Parent Credit Facility, the underwriters or placement agents or initial purchasers of any Parent Offering and their respective advisors, (ii) reasonably cooperating with prospective underwriters, placement agents or initial purchasers and their respective advisors in performing their reviews and due diligence investigation of the Assets, Assumed Liabilities and the Business, (iii) assisting with the preparation by the Parent of materials related to the Assets, Assumed Liabilities or Business for rating agency presentations, the Prospectus Supplement and any other offering documents, private placement memoranda, bank information memoranda or prospectuses and similar documents necessary or customary in connection with any Parent Offering (collectively, “Offering Documentation”), (iv) authorizing the inclusion of the Financial Statements in the Offering Documentation and the filing of this Agreement with the SEC as an exhibit to certain documents incorporated by reference therein (and the Sellers do hereby authorize the inclusion of the Financial Statements and the filing of this Agreement with the SEC) and the inclusion of all other financial statements and financial and other information of the Sellers related to the Business that are required in connection with any Parent Offering under the Securities Act or by the SEC or are reasonably requested by the underwriters, placement agents or initial purchasers of any Parent Offering, (any information authorized for such inclusion, other than this Agreement, “Seller Information”) (v) using reasonable best efforts to procure consents and other customary documentation from Ernst & Young or the internal accounting staff of the Sellers required in connection with any Parent Offering, (vi) using reasonable best efforts to cause Ernst & Young to provide customary comfort letters to any underwriters or initial purchasers of any Parent Offering consistent with SAS 72 (as amended) including standard negative assurance on any Unaudited Financial Statements it being understood that the Sellers shall have satisfied their respective obligations set forth in subclauses (i) through (vi) of this sentence if the Sellers shall have used their reasonable best efforts to comply with such obligations whether or not any applicable deliverables are actually obtained or provided. The Parent shall, promptly upon request by any of the Sellers, reimburse the Sellers for all reasonable out-of-pocket costs incurred by the Sellers or their advisors or representatives in connection with performing the foregoing obligations of the Sellers set forth in this Section 5.04(c).

(d) The Parent shall include, or cause to be included, in the Prospectus Supplement and any other Offering Documentation used after the date of this Agreement to solicit offers to purchase securities of the Parent in connection with any Parent Offering for the purpose of funding the payment of a portion of the Purchase Price, a statement substantially to the following effect:

Information contained in or incorporated by reference in this Prospectus Supplement or other Offering Documentation regarding the Business, including the Financial Statements for the Business, were obtained by us from Lafarge. Lafarge is not soliciting investments by any person in our securities or otherwise participating in this offering, and makes no representation or warranty of any kind to investors who elect to acquire our securities in this offering.

-50-

(e) The Sellers agree that, during the period commencing on the date of this Agreement and ending on the date as of which the Parent shall have notified the Sellers that it has successfully completed a Parent Offering that, together with available borrowings under the Parent Credit Facility, provides it with sufficient funds for purposes of financing the payment of the Purchase Price, if any of them shall become aware of any information that would cause any of the Seller Information to be false or misleading with respect to any material fact, it shall promptly inform the Parent in writing, and the Parent shall thereupon use its reasonable best efforts to promptly amend or supplement the Prospectus Supplement or other applicable Offering Documentation to correct the applicable misstatement or omission. Except as specifically provided herein, the Sellers shall not have any liability or responsibility to the Parent or the Purchaser for the accuracy and completeness of any Seller Information. Furthermore, the Parent shall indemnify, defend and hold harmless the Sellers, their Affiliates and any of their respective directors, officers, employees, advisors and representatives from and against any and all Losses suffered or incurred by them as a result of or based upon any Third Party Claim or any finding or determination in a Legal Proceeding that any statements included in the Prospectus Supplement or any other Offering Documentation are false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, except to the extent that the relevant misstatement or omission is based directly upon the Seller Information that was knowingly false when provided by the Seller.

SECTION 5.05. Exclusivity.

During the period from the date of this Agreement until the Closing Date, neither the Sellers nor any of their Affiliates shall, and each shall take all action required to ensure that their respective directors, officers, agents and other representatives (including any investment banker, financial advisor, attorney or accountant) do not, directly or indirectly, (i) solicit, initiate or knowingly encourage, or knowingly take any other action to facilitate, any proposal or offer relating to a transaction involving an acquisition of the Business or a substantial portion thereof (whether in the form of a merger, consolidation, stock acquisition, asset acquisition, share exchange, business combination, recapitalization or otherwise) (a “Competing Proposal”) or any inquiry or the making of any proposal that constitutes or could reasonably be expect to lead to a Competing Proposal or (ii) enter into, continue or otherwise participate in any discussions, negotiation or agreements (whether or not legally binding) regarding, or furnish to any Person (other than the Parent or the Purchaser) any information with respect to, or otherwise cooperate in any way with, any Competing Proposal.

In addition, the Sellers shall promptly provide written notice to the Parent if any supplier, insurer, lessor, licensor, licensee, distributor, customer, contractor or other Person having a material business relationship with any Seller relating to the Business informs the Sellers in writing that such Person intends to terminate or alter in any material respect such relationship because of the transactions contemplated by this Agreement.

(b) Each of the Parent and the Purchaser shall give prompt notice to the Sellers of (i) any matter hereafter arising or discovered that, if existing or known at the date of the Agreement, would have been required to be set forth or described in the Schedules prepared by the Parent hereunder (including the Schedules referred to in Article IV), (ii) the occurrence or non-occurrence of any event the occurrence or non-occurrence of which is reasonably expected to cause any representation or warranty of the Parent or the Purchaser contained in Article IV to be untrue or inaccurate in any material respect at or prior to the Closing, (iii) any failure of the Parent or the Purchaser to comply with or satisfy, in any material respect, any covenant, condition or agreement to be complied with or satisfied by any Seller hereunder, (iv) any written notice or other communication from any Person alleging that any consent, approval or authorization of such Person is or may be required in connection with the transactions contemplated by this Agreement, or (v) the commencement of any Legal Proceeding by a Governmental Authority or other Person or, to the knowledge of the Parent, threatened Legal Proceeding by a Governmental Authority or other Person that could reasonably be expected to affect the transactions contemplated hereby in any material respect; provided, however, that any such notice shall in any event be delivered to the Sellers no later than three Business Days prior to the Closing Date.

-52-

(c) The breach by any party of this Section 5.06 shall not be deemed to be a breach of a covenant, but instead shall be treated as a breach of the representation or warranty of such party whose subject matter is most similar to that of the fact, event or circumstance described herein giving rise to the notification obligations provided for in Section 5.06(a) and (b) above.

(a) The Sellers shall be liable for and shall pay to discharge when due (i) all Taxes relating to the direct or indirect ownership or operation of the Business or the Assets (including any Taxes payable under the Sugar Creek Lease) which are attributable to any taxable period or portion thereof ending on or before the Closing Date, (ii) one-half of all transfer Taxes, sales and use Taxes, goods and services, value added and similar Taxes, and withholding Taxes, if any, imposed as a result of the sale or transfer of the Assets and the Business pursuant to this Agreement, and (iii) all income, franchise or similar Taxes imposed on any of the Sellers (and any consolidated, combined, or unitary group of which any of the Sellers are a member) on account of the sale, conveyance, assignment, transfer or delivery of the Assets and the Business pursuant to this Agreement; but in each case, only to the extent the amount of such Taxes exceed the amount, if any, accrued for such Taxes and taken into account when computing Final Working Capital.

(b) The Purchaser shall be liable for and shall pay and discharge when due (i) all Taxes relating to the direct or indirect ownership or operation of the Business or the Assets (including any Taxes payable under the Sugar Creek Lease) which are attributable to any taxable period or portion thereof that begins after the Closing Date and (ii) one-half of all transfer Taxes, sales and use Taxes, goods and services, value added and similar Taxes, and withholding Taxes, if any, imposed as a result of the sale or transfer of the Assets and the Business pursuant to this Agreement.

-53-

(c) With respect to Taxes relating to the direct or indirect ownership or operation of the Business or the Assets which are attributable to a taxable period that begins on or before the Closing Date and ends after the Closing Date (a “Straddle Period”): (i) in the case of Taxes that are imposed on, or are based in whole or in part on, income, gross receipts, operations or payroll (such as income and franchise Taxes, payroll Taxes, and sales and use, value added, and goods and services Taxes), the portion of such Taxes which is attributable to the portion of such taxable period ending on or before the Closing Date shall be determined by closing the books of the Business as of the end of the Closing Date (and for such purpose, any exemption, deduction, credit or other item that is calculated on an annual basis shall be allocated to the portion of the Straddle Period ending on the Closing Date on a pro rata basis determined by multiplying the entire amount of such item allocated to the Straddle Period by a fraction, the numerator of which is the number of calendar days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period); and (ii) in the case of property Taxes, ad valorem Taxes, and other Taxes imposed on a periodic basis that are not described in subclause (i) of this Section 5.08(c), the portion of any such Tax that is attributable to the portion of the period ending on or before the Closing Date shall be considered to equal the amount of such Taxes for such taxable period, multiplied by a fraction, the numerator of which is the number of days in the portion of such taxable period that ends on the Closing Date and the denominator of which is the number of days in the entire taxable period (provided, however, that if the Tax is based on a valuation that pertains to a Tax period other than that in which the Closing Date occurs, such proration shall be recalculated at such time as actual Tax bills for such period are available and the parties shall cooperate with each other in all respects in connection with such recalculation and pay any sums due in consequence thereof to the party entitled to recover the same). For purposes hereof, Taxes attributable to any period or portion thereof ending on or before the Closing Date shall include Taxes based in whole or in part on income, gain, or receipts that accrue or are received on or before the Closing Date, payroll Taxes attributable to compensation for services performed prior to the Closing Date, sales, use, value added, goods and services and similar Taxes imposed on sales or gross receipts that accrue or are received prior to the Closing Date, and Taxes attributable to the ownership of property during period on to the Closing Date. Notwithstanding the foregoing, in no event shall the Purchaser be liable for any Taxes described in subclause (i) of this Section 5.08(c) that are imposed upon and payable by any of the Sellers (or any consolidated, combined or unitary group of which any of the Sellers is a member). The Purchaser shall cause to be prepared and duly filed all Tax Returns required to be filed with respect to any Taxes described in this Section 5.08(c) and not described in the immediately preceding sentence (the “Straddle Period Return”). Such Tax Returns shall be true, correct and accurate. For each Straddle Period Return, the Purchaser shall deliver to the Sellers, for their review and comment no less than forty-five (45) days prior to the applicable filing deadline (taking into account applicable extensions), a copy of the draft return (with copies of any relevant schedules, work papers and other documentation then available). At least thirty (30) days prior to the due date for the filing of such return (including extensions), the Sellers shall notify the Purchaser in writing of any objections to any items set forth on such returns and the parties shall address these objections in accordance with Section 5.08(h).

-54-

(d) Except as otherwise set forth in this Agreement, to the extent any refunds or credits with respect to Taxes paid with respect to the Assets or the Business are attributable to taxable years or a portion thereof ending before the Closing Date, such refunds or credits, less Purchaser’s reasonable expenses of obtaining such refunds or credits, shall belong to the Seller that operated the relevant Asset or portion of the Business (provided that the Purchaser shall pay over such refund, less such expenses, to the party identified by Lafarge). Except as provided in the immediately preceding sentence, to the extent that any refunds or credits with respect to Taxes paid with respect to the Assets or the Business are attributable to taxable years or a portion thereof commencing on or after the Closing Date, such refunds or credits, less the Sellers’ reasonable expenses of obtaining such refunds or credits, shall belong to the Purchaser. The Sellers and the Purchaser shall equitably apportion any refund or credit, net of expenses of obtaining such refunds or credits, with respect to Taxes for any Straddle Period in a manner consistent with the principles set forth in Section 5.08(c). Notwithstanding anything in this Section 5.08(d) to the contrary, refunds or credits, less the Sellers’ reasonable expenses of obtaining such refunds or credits, with respect to Taxes paid with respect to the Assets or the Business shall belong to the Purchaser if (and to the extent) such refunds or credits were taken into account when computing the Final Working Capital. The Purchaser shall forward to the Sellers or reimburse the Sellers for the amount of such refunds or credits belonging to the Sellers under this Section 5.08(d) within thirty (30) Business Days from receipt thereof by the Purchaser (provided that, for such purpose, a credit shall be deemed received on the due date for the Taxes it is actually applied against). The Sellers shall forward to the Purchaser or reimburse the Purchaser for the amount of any refunds or credits belonging to the Purchaser under this Section 5.08(d) within thirty (30) Business Days from receipt thereof by the Sellers (provided that, for such purpose, a credit shall be deemed received on the due date for the Taxes it is actually applied against).

(e) Without the review and consent of the Sellers (which consent may not be unreasonably withheld, conditioned or delayed), none of the Purchaser, the Parent nor any of their Affiliates shall file or make a formal or informal claim for refund or file any amended Tax Returns attributable to the Business or the Assets for any taxable years or periods ending before the Closing Date or for a Straddle Period.

(f) On and after the Closing Date, each of the Sellers and the Purchaser shall:

(i) use commercially reasonable efforts (x) to cooperate fully in preparing for any audits of, or disputes with Governmental Authorities regarding, any Tax Returns relating to the Assets or the Business, (y) to cooperate fully to obtain refunds or credits with respect to Taxes paid with respect to the Assets or the Business and (z) make available to the other and to any Governmental Authority as reasonably requested all information, records, and documents relating to liabilities for Taxes associated with the Business or the Assets as set forth in this Agreement, at the expense of the requesting party;

-55-

(ii) make available to the requesting party (at the expense of the requesting party), as reasonably requested and available, personnel responsible for preparing or maintaining information, records and documents in connection with Taxes as well as any related litigation; and

(iii) preserve all such information, records, and documents until the expiration of any applicable statutes of limitation or extensions thereof and as otherwise required by Law.

(g) Tax Claims.

(i) In case of any claim, audit, investigation, court proceeding or other dispute with respect to any Tax matter that affects the Business or the Assets (a “Tax Claim”) which, if successful, might result in an indemnity payment under Article VIII, the indemnified party shall notify the indemnifying party of such claim no later than ten (10) Business Days after written notice of such Tax Claim is received by the indemnified party; provided, however, that the failure to provide timely notice shall not affect the indemnified party’s right to indemnification hereunder except to the extent that the indemnifying party is actually prejudiced thereby.

(ii) With respect to any Tax Claim relating to (A) Taxes attributable to (1) the Excluded Assets for any and all periods or (2) the Business or the Assets, in each case, for any and all periods ending before the Closing Date; or (B) any other Taxes for which the Sellers might be entirely liable, the Sellers shall have the right (but not the duty) to control any resulting proceedings and to determine whether and when to settle any such claim, assessment, or dispute.

(iii) The Sellers on the one hand and the Purchaser on the other hand shall jointly control and participate in all proceedings in connection with (A) any Tax Claim relating to Taxes for any Straddle Period and (B) any Tax Claim which may result in a liability both for the Sellers and the Purchaser. The costs incurred by the Sellers and the Purchaser in connection with such proceedings shall be borne by the Sellers and the Purchaser in proportion to their liability for the Taxes asserted in the Tax Claim. Neither the Sellers nor the Purchaser shall settle or compromise any such Tax Claim without the prior written consent of the other, which consent shall not be unreasonably withheld, conditioned or delayed.

(iv) Except as otherwise provided in this Section 5.08, the Purchaser shall control all proceedings with respect to Tax Claims attributable to the Business and the Assets for any taxable year or period beginning on or after the Closing Date.

(v) This Section 5.08 (and not Section 8.04) shall govern with respect to any Tax matter.

(h) If the Sellers and the Purchaser disagree as to the amount of Taxes for which each is liable under this Agreement, the Sellers and the Purchaser shall promptly consult each other in an effort to resolve such dispute. If any such dispute cannot be resolved within fifteen (15) days after the initial date of consultation, then each party shall

-56-

deliver simultaneously to the Accounting Arbiter such work papers and other reports and information relating to the disputed matter(s) as the Accounting Arbiter may request and shall be afforded the opportunity to discuss the disputed matter(s) with the Accounting Arbiter. The Accounting Arbiter shall have thirty (30) days to carry out its review and prepare a written statement of its determination regarding the disputed matter(s) (including a statement regarding the Accounting Arbiter’s determination of the prevailing party in any such disputed matter that provides the Accounting Arbiter’s reasons for and an explanation of such determination), which determination shall be final and binding upon the parties. Any fees and expenses of the Accounting Arbiter incurred in resolving the disputed matter(s) shall be borne equally by the parties; provided, however, that a party shall bear all of the costs of such resolution if the Accounting Arbiter determines that such party’s position was in bad faith or without merit.

SECTION 5.09. Proration of Certain Amounts and Utilities.

(a) The parties agree to prorate as of 11:59 p.m. Central Standard Time on the day of the Closing (the “Effective Time”) any utilities, expenses and other items (other than (i) the allocation and proration of Taxes provided for in Section 5.08 and (ii) any amounts to be reflected in Net Working Capital pursuant to the Working Capital Principles) that are customarily prorated in connection with transactions similar to the transactions contemplated by this Agreement, including operating expenses payable by the owner of the Assets and rent paid pursuant to the Leases for the Leased Real Property (collectively, the “Proration Items”). Proration Items attributable to the period prior to the Effective Time will be for the account of the Sellers and Proration Items attributable to the period after the Effective Time will be for the account of the Purchaser and each party will be responsible for the payment of its prorated share of the Proration Items. If the actual amounts of the Proration Items are not known as of the Effective Time, the prorations will be made at Closing on the basis of the best evidence then available; thereafter, when the actual amount of any such Proration Item is received (and in no event later than 30 days after the receipt of such amount), a re-proration will be made on the basis of the actual amount and the parties shall reimburse each other accordingly.

(b) Promptly after the Closing (but in any event, no later than 30 days thereafter), the Purchaser shall notify all relevant utilities that the name of the Purchaser (or the name of an Affiliate of the Purchaser designated by it) should replace the name of the Sellers on all utility bills and that the Purchaser or such designee will be responsible for payment of all utility bills going forward.

SECTION 5.10. Certain Employee Matters.

(a) Prior to the Closing Date, Seller shall update the list of the Employees as disclosed on Schedule 5.10(a) hereto to reflect new hires and terminations of employment between the date of this Agreement and November 2, 2012.

(b) Prior to or on November 16, 2012, the Purchaser or an Affiliate thereof (each a “Purchaser Benefit Party,” and collectively, “Purchaser Benefit Parties”) shall make offers of employment in writing to the Employees who are set forth on the list

-57-

described in Section 5.10(a), which offers shall be for employment with the Purchaser or a Purchaser Benefit Party commencing on the applicable Employee Commencement Effective Time and otherwise on the terms and conditions set forth in this Section 5.10. Each such Employee shall have five (5) Business Days from the receipt of such an offer to accept. Neither the Sellers nor any of its Affiliates (each a “Seller Benefit Party,” and collectively, “Seller Benefit Parties”) shall induce or otherwise attempt to influence any such Employee to resign or to not accept his or her offer of employment from the Purchaser. Each Employee, who shall have accepted the Purchaser’s offer of employment and who shall meet the Purchaser Benefit Parties’ conditions of employment described in Schedule 5.10(b)(i) hereto (the “Purchaser Employment Conditions”) shall be hired by the applicable Purchaser Benefit Party, it being understood that (i) such Employee will thereafter become an employee of such Purchaser Benefit Party (“Purchaser Employee”) for purposes of this Section 5.10 effective as of the applicable Employee Commencement Effective Time and (ii) the parties hereto and their Affiliates will cooperate in good faith to effect the hiring of any Employees set forth on the list described in Section 5.10(a), who (x) are absent from work due to short or long-term disability or an authorized leave of absence and return to work within ninety (90) days following the Closing Date, and (y) shall meet the Purchaser Employment Conditions (any such Employee, a “Leave Employee”). If any Employee requires a work permit or employment pass as disclosed on Schedule 5.10(b)(ii) hereto for his or her employment with the Purchaser or any of the Purchaser Benefit Parties, the Purchaser shall, and shall cause the Purchaser Benefit Parties to, use commercially reasonable efforts to cause any such permit or pass to be obtained and in effect prior to the Employee Commencement Effective Time, and the Sellers shall, and shall cause the Seller Benefit Parties to, take all reasonably necessary or appropriate action at the Purchaser’s expense, as reasonably requested by the Purchaser, to assist in obtaining any such permit or pass prior to the Employee Commencement Effective Time.

(c) The Purchaser’s offers of employment to each Employee shall provide for employment on the following terms and conditions, which terms and conditions the Purchaser shall maintain or cause the applicable Purchaser Benefit Party to maintain for each Purchaser Employee for at least twelve (12) months following the Closing Date (or such shorter period as a Purchaser Employee is employed by the Purchaser following the Closing Date): (i) employment in a comparable position to the position such Employee held with the Sellers or their Affiliates immediately prior to the Closing Date, (ii) the same or greater base salary or rate of pay as in effect immediately prior to the Closing Date, (iii) other compensation and employee benefits that are substantially equivalent in the aggregate to the compensation and benefits that are provided by Sellers and its Affiliates to such Employee immediately prior to the Closing Date, and (iv) severance payments and benefits that are substantially equivalent to the severance benefits provided to Employees under Lafarge North America Inc. Severance Pay Plan; provided, however, that the terms and conditions of the Purchaser Employees who are covered by the Labor Agreements (the “Represented Employees”) shall be as set out in the applicable Labor Agreement until such Labor Agreement’s expiration, modification or termination in accordance with its terms or applicable Law.

-58-

(d) Prior to the Closing, the Sellers and the Purchaser shall cooperate and the Purchaser shall take all action reasonably necessary in order for the Purchaser to assume, effective for periods after the Closing, the Labor Agreements; provided, that the liabilities and obligations under the Labor Agreements shall be assumed only to the extent that such liabilities and obligations arise, relate to and are required to be performed during periods after the Closing. Notwithstanding any provision in this Agreement to the contrary, in no event shall the Purchaser Benefit Parties become responsible for liabilities or other obligations under the Labor Agreements that arise or otherwise relate to periods occurring prior to the Closing. The Purchaser shall give written notice to the counterparties to the Labor Agreements regarding Purchaser’s assumption of the Labor Agreements when and as required by the Labor Agreements.

(e) As soon as practicable following the Closing, the Purchaser shall enter into arrangements with the Multiemployer Plans described in Schedule 5.10(e) hereto (“Covered Multiemployer Plans”) to become a new contributing employer therein with respect to the Business and effective for periods on and after the Closing. With respect to the Covered Multiemployer Plans, the parties acknowledge and agree that they do not intend for the transactions contemplated by this Agreement to constitute a withdrawal from the Covered Multiemployer Plans but instead intend to satisfy the conditions set forth in Section 4204 of ERISA in respect of the Covered Multiemployer Plans. In furtherance thereof, the parties agree that they will cooperate in supplying information, documents and communications with the Covered Multiemployer Plans involved, and that the Purchaser shall maintain, for a period of five (5) plan years commencing with the first (1^st) plan year beginning after the Closing Date, either a bond issued by a corporate surety company that is an acceptable surety for purposes of Section 412 of ERISA or an amount held in escrow by a bank or similar financial institution, satisfactory to such Covered Multiemployer Plan (as applicable, “4204 Bond”), which bond or escrow will be paid to the applicable Covered Multiemployer Plan if the Purchaser withdraws from the Covered Multiemployer Plan or fails to make a contribution when due at any time during the first five (5) plan years beginning after the Closing Date, in an amount equal to the greater of:

(i) the average annual contribution required to be made by the Sellers and Seller Benefit Parties to the Covered Multiemployer Plan with respect to the operations under the applicable Labor Agreement for the three (3) plan years preceding the plan year in which the Closing Date occurs; and

(ii) the annual contribution that the Sellers and Seller Benefit Parties were required to make to the Covered Multiemployer Plan with respect to the operations under the applicable Labor Agreement for the last plan year prior to the plan year in which the Closing Date occurs.

The Sellers acknowledge and agree that they will be secondarily liable to each Covered Multiemployer Plan for withdrawal liability if the Purchaser withdraws from either Covered Multiemployer Plan within five (5) years and does not pay its withdrawal liability and any such withdrawal liability shall be considered an Assumed Liability under this Agreement and the Parent and the Purchaser shall indemnify the Sellers for any such amounts.

-59-

The Sellers further acknowledge and agree that if the Purchaser (or its Affiliate) incurs any withdrawal liability related to a Covered Multiemployer Plan due to a Non-Purchaser Withdrawal Event (as defined below) and the 4204 Bond is to be paid to the Covered Multiemployer Plan due to such Non-Purchaser Withdrawal Event, then the Sellers shall indemnify and promptly pay to the Purchaser the 4204 Bond amount paid to the Covered Multiemployer Plan. For purposes of this Section 5.10(e), a “Non-Purchaser Withdrawal Event” means any event or action that triggers a withdrawal liability with respect to a Covered Multiemployer Plan during the period that the 4204 Bond is required other than due to the Purchaser’s (or its Affiliate’s) withdrawal from the Covered Multiemployer Plan, which events or actions shall include, but are not limited to, (i) a collective bargaining representative’s disclaimer of interest in representing the employees of the Purchaser (or its Affiliate) who participate in the Covered Multiemployer Plan; (ii) a “mass withdrawal,” as defined in 29 Code of Federal Regulations (C.F.R.) § 4001.2, from the Covered Multiemployer Plan; (iii) a decertification of the collective bargaining representative to which the Covered Multiemployer Plan relates; or (iv) the termination of the Covered Multiemployer Plan pursuant to Sections 4041A(a) or 4042 of ERISA and any rules and regulations issued thereunder.

(f) As soon as practicable following the execution of this Agreement, and notwithstanding any provision herein to the contrary, the parties shall commence, and shall cooperate in connection with, the drafting of separate plan documents and related contracts thereto that shall be substantially similar to the Seller DB Retirement Plans described in Schedule 5.10(f) hereto (the “Mirror Plans”). Subject to this Section 5.10(f), the Mirror Plans shall provide benefits that are substantially identical to the benefits provided immediately prior to the Closing to the Purchaser Employees under the Seller DB Retirement Plans described in Schedule 5.10(f) hereto, it being understood that in no event shall the Mirror Plans be construed to provide any duplication of benefits to the Purchaser Employees with respect to any accrued benefits or other obligations to which the Purchaser Employees are otherwise entitled under such Seller DB Retirement Plans. In furtherance of the foregoing, the benefits to be provided to a Purchaser Employee under the Mirror Plans shall be determined based on such Purchaser Employee’s total service with the Sellers and Seller Benefit Parties and their respective predecessors (to the extent required to be taken into account under the applicable Seller DB Retirement Plans described in Schedule 5.10(f) hereto) and with the Purchaser and Purchaser Benefit parties, less the value of any accrued benefits as of the Closing Date under the Seller DB Retirement Plans (such accrued benefits frozen as of the Closing Date), with respect to each such Purchaser Employee under such Seller DB Retirement Plans. As soon as practicable following the Closing Date, each Mirror Plan shall be adopted by one or more of the Purchaser Benefit Parties, and modified as necessary, as a new employee benefit plan for the benefit of the applicable Purchaser Employees who participated immediately prior to the Closing Date in the applicable Seller DB Retirement Plans described in Schedule 5.10(f) hereto. For the avoidance of doubt and notwithstanding any provision herein to the contrary, with respect to any Seller DB Retirement Plan that is not described in Schedule 5.10(f) hereto, the Seller Benefit Parties shall retain all responsibility for all liabilities or other obligations under such Seller DB Retirement Plan.

-60-

(g) The Sellers will be responsible for discharging all obligations in respect of Employees under the WARN Act and similar applicable state or local Laws for the notification of any “employment loss” within the meaning of the WARN Act and similar applicable state or local Laws which occurs on or prior to the Closing. The Purchaser will be responsible for discharging all obligations in respect of the Purchaser Employees under the WARN Act and similar applicable state or local Laws for the notification of any “employment loss” within the meaning of the WARN Act and similar applicable state or local Laws which occurs after the Closing. The Sellers will provide the Purchaser at Closing a list of Employees whose employment has been involuntarily terminated or who have been notified of their termination by Seller (other than as a result of the transactions contemplated by this Agreement) during the 90-day period ending on the Closing Date.

(h) As soon as practicable following the Closing Date and with respect to the Benefit Plans described in Schedule 3.21(a) hereto that are qualified defined contribution plans, the Purchaser and the Purchaser Benefit Parties shall permit the Purchaser Employees to roll over their account balances and outstanding loan balances, if any, thereunder into any applicable “eligible retirement plan” within the meaning of Section 402(c)(8)(B) of the Code maintained by a Purchaser Benefit Party thereof after the Closing, subject to any restrictions on loan balance transfers under such plan.

(i) As soon as practicable following the Closing Date, the Purchaser shall permit the Purchaser Employees, as well as dependents of such employees (collectively, with the Purchaser Employees, the “Affected Participants”) to commence participation in the applicable employee benefit plans, programs or policies, if any, maintained by the Purchaser Benefit Parties (each, a “Purchaser Plan”); provided, that, with respect to the Purchaser Plans that provide health benefits (i.e., medical, dental, prescription drug and vision benefits) (the “Purchaser Health Plans”), the Affected Participants shall be permitted to commence participation in the Purchaser Health Plans on the later of (i) January 1, 2013 and (ii) the Closing Date with respect to periods occurring on and after such date. The Purchaser shall waive any evidence of insurability, waiting period and preexisting condition limitations with respect to the participation and coverage requirements under the Purchaser Health Plans except to the extent that any limitations were in effect immediately prior to the Closing Date under the analogous Benefit Plan. In the event the parties waive any applicable conditions and the Closing occurs after December 31, 2012, with respect to each Purchaser Health Plan, the Purchaser shall honor any deductible, co-payment and out-of-pocket maximums incurred by the Affected Participants under the health plans in which they participated immediately prior to the Closing Date during the portion of the calendar year prior to the Closing Date in satisfying any deductibles, co-payments or out-of-pocket maximums under Purchaser Health Plans in the same plan year in which such deductibles, co-payments or out-of-pocket maximums were incurred. With respect to each such Purchaser Plan, the Purchaser shall cause each Purchaser Employee to receive full credit for such Employee’s service with the Sellers and the Seller Benefit Parties and any of their respective predecessors for purposes of eligibility, vesting and, to the extent necessary under Section 5.10(f), benefit accruals, under any Purchaser Plans in which any such Purchaser Employee participates to the same extent recognized by the Sellers and the Seller Benefit Parties immediately prior to the Closing Date; provided, however, that such service shall not be recognized to the extent

-61-

that such recognition would result in a duplication of benefits with respect to the same period of service. It is also understood that, except as otherwise provided herein, the Purchaser Benefit Parties reserve the right to change, modify, discontinue or terminate any or all of its own welfare benefit plans (including welfare benefit plans that are established pursuant to the transactions contemplated under this Agreement) at any time following the Closing Date.

(j) Notwithstanding any provision herein to the contrary, if the Closing occurs prior to December 1, 2012, Sellers shall provide the Purchaser Employees with COBRA continuation coverage required under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, or similar state Law (“COBRA”) through December 31, 2012, pursuant to the Transition Services Agreement and to the extent permitted by applicable Law, subject in each case to such Purchaser Employee’s timely election in accordance with applicable Law. The Sellers shall provide the Purchaser Employees with information regarding their entitlement to make, and the process for making, COBRA elections, and the Purchaser shall provide reasonable assistance and cooperation to the Sellers to the extent necessary to effectuate the parties’ intentions in respect of this provision. The Purchaser shall reimburse the Sellers, directly or indirectly, for all costs incurred by the Sellers in connection with the provision of COBRA continuation coverage to Purchaser Employees. During any calendar month in which a Purchaser Employee participates in COBRA continuation coverage and pursuant to the Transition Services Agreement, the Purchaser shall be responsible for paying with respect to such Purchaser Employee one hundred two percent of monthly COBRA premiums charged by the Sellers, net of the Employee Premium (the “Purchaser COBRA Premium,” and collectively the “Purchaser COBRA Premiums”). For purposes of this Section 5.10, “Employee Premium” shall be equal to the employee contribution payable by a Purchaser Employee to Sellers or Seller Benefit Parties immediately prior to the Closing Date in connection with the employee’s participation in Benefit Plans that provide health benefits (i.e., medical, dental, prescription drug and vision benefits). The Sellers or Sellers’ service provider, Aetna, shall provide to the Purchaser a monthly invoice for the Purchaser COBRA Premium in respect of all Purchaser Employees participating in COBRA continuation coverage, and the Purchaser shall pay the amounts stated in the invoice in full pursuant to the procedure set forth in the Transition Services Agreement but in any event no later than thirty days of the invoice being issued to an account designated by the Purchaser. After information regarding payments of claims for eligible expenses incurred by Purchaser Employees in connection with any medical, vision, dental and prescription drug claims becomes available for the month in respect of which the invoice for Purchaser COBRA Premiums has been issued, the Sellers or Sellers’ service provider, Aetna, shall calculate, and shall provide to the Purchaser a true-up invoice for, the COBRA True Up Amount (unless such amount is zero), and the Purchaser shall pay the COBRA True Up Amount in full pursuant to the procedure set forth in the Transition Services Agreement but in any event no later than thirty days of the true-up invoice being issued to an account designated by the Purchaser. For purposes of this Section 5.10, the “COBRA True-Up Amount” shall be, in respect of a calendar month, an amount equal to the excess, if any, of all payments of claims for eligible expenses incurred during such month by Purchaser Employees participating in COBRA continuation coverage in connection with any medical, vision, dental and prescription drug claims over the aggregate amount of Purchaser COBRA Premiums for such month.

-62-

(k) Subject to the Transition Services Agreement, the Seller Benefit Parties shall be solely responsible for offering and providing any COBRA continuation coverage, with respect to any Employee (whether current, former or retired) who experiences a qualifying event on or prior to the Closing without regard to whether the coverage loss occurs before, on or after the Closing, and for any Employee who does not become a Purchaser Employee and who experiences a qualifying event after the Closing or who otherwise loses eligibility for coverage in connection with the transactions contemplated under this Agreement. Notwithstanding the foregoing, the Purchaser Benefit Parties shall be solely responsible for offering and providing any COBRA continuation coverage required with respect to any Purchaser Employee who experiences a qualifying event after the Closing. “Qualifying event” and “continuation coverage” are as defined in Section 4980B of the Code and the regulations promulgated thereunder.

(l) The parties to this Agreement agree to furnish each other with such information concerning employees and employee benefit plans, including, but not limited to, copies of administrative service agreements and other contracts that may relate to Seller DB Retirement Plans described in Schedule 5.10(f) hereto and are reasonably requested by Seller (or if such documents cannot be provided pursuant to their terms or the provision of such documents would be impractical, information regarding the vendors who are parties to such arrangements and the material terms thereof, to the extent such information may be disclosed by Seller under applicable Law and the terms of such arrangements), and to take all such other action, as is necessary and appropriate to effect the transactions contemplated by this Section 5.10, subject to any applicable restrictions under the Health Insurance Portability and Accountability Act of 1996, as amended, and other federal and state privacy Laws. Where any required information is in the possession of third parties controlled by a Seller Benefit Party, such as insurers or trustees, the Seller Benefit Parties shall use reasonable efforts to cause those third parties to cooperate in providing any such information to the Purchaser or Purchaser Benefit Party. The parties will reasonably cooperate with respect to any communications to Employees regarding the transactions contemplated by this Agreement. The Purchaser will provide the Sellers with a reasonable opportunity to review and comment on any communications intended for the Employees (including regarding its offers of employment) that it desires to send to Employees prior to the Closing Date.

(m) The Sellers shall be, or shall cause the Seller Benefit Parties to be, responsible, either directly or through insurance policies maintained by the Sellers or the Seller Benefit Parties, for all (i) medical, vision, dental and prescription drug claims for eligible expenses incurred by any Purchaser Employee or his or her dependents (x) during the month in which the Closing Date occurs, if the Closing occurs in November 2012 or December 2012 or (y) prior to the applicable Employee Commencement Effective Time, if the parties waive any applicable conditions and the Closing occurs after December 31, 2012, (ii) claims for short-term and long-term disability income benefits incurred by any Purchaser Employee prior to the applicable Employee Commencement Effective Time, and (iii) claims for group life, travel and accident, and accidental death and

-63-

dismemberment insurance benefits incurred by any Purchaser Employee prior to the applicable Employee Commencement Effective Time; provided that if the Closing occurs in November 2012 or December 2012, the Purchaser shall promptly reimburse the Seller for the amounts equal to the eligible expenses incurred by Purchaser Employees in connection with any medical, vision, dental and prescription drug claims arising from the Closing Date through the end of the month in which the Closing occurs (net of pro rata portion of aggregate Employee Premiums) upon the presentation by Seller of an invoice setting forth its costs. The Purchaser shall be, or shall cause the Purchaser Benefit Parties to be, responsible for all (A) medical, vision, dental and prescription drug claims for eligible expenses incurred by any Purchaser Employee or his or her dependents (x) during any month that follows the month in which the Closing Date occurs, if the Closing occurs in November 2012 or December 2012 (provided that any claims incurred by Purchaser Employees participating in COBRA continuation coverage will be paid by the Sellers and reimbursed by the Purchaser in accordance with Section 5.10(j) of this Agreement) or (y) after the applicable Employee Commencement Effective Time, if the parties waive any applicable conditions and the Closing occurs after December 31, 2012, (B) claims for short-term and long-term disability income benefits incurred by any Purchaser Employee on or after the applicable Employee Commencement Effective Time, and (C) claims for group life, travel and accident, and accidental death and dismemberment insurance benefits incurred by any Purchaser Employee on or after the applicable Employee Commencement Effective Time. Except in the event of any claim for workers compensation benefits, for purposes of this Agreement, the following claims and liabilities shall be deemed to be incurred as follows: (i) medical, vision, dental and/or prescription drug benefits (including hospital expenses), upon provision of the services or supplies comprising any such benefits; and (ii) short and long-term disability, life, accidental death and dismemberment and business travel accident insurance benefits, upon the death, illness, injury or accident giving rise to such benefits. The Sellers and the Seller Benefit Parties shall be responsible for all claims for workers compensation benefits that are incurred prior to the applicable Employee Commencement Effective Time by any Purchaser Employee. The Purchaser and the Purchaser Benefit Parties shall be responsible for all claims for workers compensation benefits that are incurred on or after the applicable Employee Commencement Effective Time by any Purchaser Employee. A claim for workers compensation benefits shall be deemed to be incurred when the event giving rise to the claim occurs.

(n) Lafarge hereby waives compliance by the Parent and the Purchaser with the non-solicitation and other restrictions contained in Section 11 of that certain letter agreement, dated July 2, 2011, between the Parent and Lafarge, and Section 10 of the Confidentiality Agreement solely with respect to any solicitation of or offers of employment made to the Employees in accordance with the terms of this Section 5.10 in connection with the transactions contemplated hereby.

(o) From and after the Closing Date, each Seller hereby waives any non-competition obligations or any other restriction on the activities of any Purchaser Employee that arise pursuant to any employment or other agreement between any such employee and any Seller that would otherwise prevent or restrict in any way such employee from at any time performing his or her obligations or responsibilities (as they may exist from time to time as determined by the Purchaser) to or for the Purchaser or its Affiliates.

-64-

(p) Except as otherwise expressly set forth in this Section 5.10, the Purchaser shall be, and shall cause the Purchaser Benefit Parties to be, responsible for any employment-related claims, liabilities or obligations to the extent such claim, liabilities or obligations arise or otherwise relate to periods occurring after the Closing, and the Sellers shall, and shall cause the Seller Benefit Parties to, remain responsible for any and all employment-related claims, liabilities or obligations to the extent such claim, liabilities or obligations arise or otherwise relate to periods occurring prior to the Closing.

(q) Purchaser shall assume the obligation to pay and shall pay, and shall cause Purchaser Benefit Parties to pay, to the Purchaser Employees accrued bonuses in respect of 2012 consistent with the principles of the Sellers’ bonus program (as specified on Schedule 5.10(q) hereto) and the calculation of Net Working Capital pursuant to the Working Capital Principles.

(r) The parties hereto acknowledge and agree that all provisions contained in this Section 5.10 with respect to employees are included for the sole benefit of the respective parties hereto and shall not create any right (i) in any other person, including any employees, former employees, any participant in any Benefit Plan or Purchaser Plan or any beneficiary thereof or (ii) to continued employment with any of the Seller Benefit Parties or Purchaser Benefit Parties, or particular benefits or coverage in any Benefit Plan or Purchaser Plan. For the avoidance of doubt, (A) the provisions of this Section 5.10 shall not constitute an amendment to any Benefit Plan or Purchaser Plan, and (B) in no event shall any employee, former employee, any participant in any Benefit Plan or Purchaser Plan or any beneficiary thereof or any other person described herein be a third party beneficiary for purposes of this Agreement.

(i) the Sellers shall not, directly or indirectly, (A) redeem or tender any of the Series B Bonds, (B) accept any amounts as a prepayment in full of the principal balance owing to any of the Sellers in respect of the Series B Bonds or (C) agree or commit to take the actions specified in subclause (A) or (B) above;

(iv) notwithstanding the provisions of Section 5.08, the Sellers shall comply with the Sugar Creek Tax Compliance Agreement and shall not take any action or permit any action to be taken that would adversely affect the exclusion from gross income for federal income tax purposes of the interest on the Series A Bonds and will take whatever action, or refrain from taking whatever action, necessary to comply with the requirements of the Code to maintain the exclusion from gross income for federal income tax purposes of the interest on the Series A Bonds, and the Sellers will pay or provide for payment to the United States Government, all rebate payments required under Section 148(f) of the Code and the Sugar Creek Tax Compliance Agreement accrued at any time prior to or on the Closing Date; and

(v) the Sellers shall comply with all other covenants, terms and provisions applicable to any of them under the IRD Bond Documents.

(c) The Parent shall use its reasonable best efforts to cause Lafarge to (and Lafarge shall cooperate with the Parent in connection therewith) be fully released and discharged from all Assumed Liabilities under the IRB Bond Indenture, the Sugar Creek Guaranty, the Sugar Creek Lease and the Sugar Creek Development Agreement (including by offering guarantees of all such obligations). If, at or prior to the Closing, Lafarge is not discharged from all such Assumed Liabilities, the parties shall use reasonable best efforts to enter into reasonably satisfactory alternative arrangements designed to limit the liability of Lafarge to all such Assumed Liabilities as much as reasonably practicable.

SECTION 5.12. Related Party Matters.

At or prior to the Closing, the Sellers will cause to be terminated any Contract or other arrangement relating to the Business solely between or among the Sellers or any of their Affiliates that would otherwise be binding on or affect the Purchaser after the Closing and none of the Sellers, on the one hand, nor the Parent or the Purchaser, on the other, will have any obligations to the other thereunder. After the Closing, no services, commitments or other arrangements existing prior to Closing between the Business, on the one hand, and any other business of any Seller or any of its Affiliates, on the other hand, will continue to be binding or effective. Notwithstanding the previous sentences of this Section 5.12, the Sellers shall not be required to terminate the National Contracts, which are Excluded Assets. For the avoidance of doubt, this Section 5.12 does not apply to the Ancillary Agreements.

-66-

SECTION 5.13. Confidential Information.

(a) Each of the Sellers hereby acknowledges that by reason of its ownership and operation of the Business, it has acquired, and may acquire in connection with the transactions and arrangements contemplated hereby, confidential or proprietary information relating to the affairs, operations, assets, liabilities, personnel, results of operations and financial condition of the Business (“Business Confidential Information”), and that the Parent and the Purchaser may be irreparably damaged if at any time after the Closing any Business Confidential Information possessed by any Seller or any of its Affiliates, officers, directors, employees, representatives or agents were disclosed to or used by any Person other than the Purchaser, the Parent or any of its their respective Affiliates. From and after the Closing, each Seller covenants and agrees that it will not, and will not permit its Affiliates to, and that it will use reasonable efforts to cause its officers, directors, employees, representative and agents not to, use or disclose any such Business Confidential Information without the prior written consent of the Purchaser, except in the performance of the terms of the Agreement or the Ancillary Agreements, in the enforcement of its rights under the Agreement or the Ancillary Agreements or with the prior written consent of the Purchaser. The provisions of the prior sentence shall not apply to any portion of the Business Confidential Information that (i) is or becomes generally known by the public, other than as a result of a disclosure in breach of this Section 5.13(a), (ii) is independently obtained on a non-confidential basis after the Closing from sources that are not known by any of the Sellers to be in violation of any legal, contractual or fiduciary obligation to the Parent or the Purchaser with respect thereto or otherwise prohibited by Law, contract or fiduciary duty from disclosing such information or (iii) is independently developed after the Closing by the Sellers without the use of or reference to any Business Confidential Information. If any Seller is requested or required by any Governmental Authority to disclose any of such Business Confidential Information, then such Seller will provide the Purchaser with prompt written notice of such request or requirement. Each Seller shall reasonably cooperate with the Purchaser, at the Purchaser’s expense, in attempting to obtain any reasonable protective relief that the Purchaser chooses to seek in its sole discretion; provided, however, that none of the Sellers shall be obligated to undertake any Legal Proceeding. If after the Purchaser has had a reasonable opportunity to seek such relief, the Purchaser fails to obtain such relief, or if any Seller is compelled by Law to disclose any Business Confidential Information, then the applicable Seller may disclose only the portion of such Business Confidential Information which its legal counsel advises it is legally compelled to disclose, and the applicable Seller shall exercise commercially reasonable efforts, at the Purchaser’s expense, to obtain assurances that the Business Confidential Information will be accorded confidential treatment.

(b) The Purchaser hereby acknowledges that it may acquire, pursuant to the rights granted in Section 1.01(a)(xvii) or otherwise in connection with the transactions and arrangements contemplated hereby, confidential or proprietary information relating to the affairs, operations, assets, liabilities, personnel, results of operations and financial condition of the Sellers (such information, excluding all Business Confidential Information, is referred to as the “Seller Confidential Information”) and that the Sellers may be irreparably damaged if at any time after the Closing any Seller Confidential Information acquired by the Purchaser or any of its Affiliates, officers, directors,

-67-

employees, representatives or agents were disclosed to or used by any Person other than the Purchaser, the Parent or any of its their respective Affiliates. From and after the Closing, the Purchaser covenants and agrees that it will not, and will not permit its Affiliates to, and that it will use reasonable efforts to cause its officers, directors, employees, representative and agents not to, use or disclose any such Seller Confidential Information without the prior written consent of Lafarge, except in the performance of the terms of the Agreement or the Ancillary Agreements, in the enforcement of its rights under the Agreement or the Ancillary Agreements or with the prior written consent of Lafarge. The provisions of the prior sentence shall not apply to any portion of the Seller Confidential Information that (i) is already independently in the Purchaser’s or its Affiliates possession on a non-confidential basis (to a third-party) at the time of disclosure thereof, (ii) is or becomes generally known by the public, other than as a result of a disclosure in breach of this Section 5.13(b), (iii) is independently obtained on a non-confidential basis after the Closing from sources that are not known by the Purchaser to be in violation of any legal, contractual or fiduciary obligation to the Sellers with respect thereto or otherwise prohibited by Law, contract or fiduciary duty from disclosing such information or (iv) is independently developed after the Closing by the Purchaser or its Affiliates without the use of or reference to any Seller Confidential Information. If the Purchaser is requested or required by any Governmental Authority to disclose any of such Seller Confidential Information, then the Purchaser will provide Lafarge with prompt written notice of such request or requirement. The Purchaser shall reasonably cooperate with the Sellers, at the Sellers’ expense, in attempting to obtain any reasonable protective relief that the Sellers choose to seek in its sole discretion; provided, however, that the Purchaser shall not be obligated to undertake any Legal Proceeding. If after the Sellers have had a reasonable opportunity to seek such relief, the Sellers fail to obtain such relief, or if the Purchaser is compelled by Law to disclose any Seller Confidential Information, then the Purchaser may disclose only the portion of such Seller Confidential Information which its legal counsel advises it is legally compelled to disclose, and the Purchaser shall exercise commercially reasonable efforts, at the Sellers’ expense, to obtain assurances that the Seller Confidential Information will be accorded confidential treatment.

(c) The obligations of the Parent and its Affiliates pursuant to the Confidentiality Agreement or any other confidentiality or non-disclosure agreement among any of the Sellers or any of their Affiliates, on the one hand, and the Parent or any of its Affiliates, on the other hand, in respect of Business Confidential Information shall terminate as of the Closing and cease to be of any further force or effect.

(d) Nothing contained in this Section 5.13 or elsewhere in this Agreement shall alter or otherwise affect the obligations of the Parent, Lafarge or Lafarge S.A. under the confidentiality agreement, dated as of July 2, 2011 among such parties.

SECTION 5.14. Delivery of Cash; Certain Communications.

SECTION 5.17. Title Matters.

(a) The Purchaser acknowledges having received written copies of the title reports issued by the Title Company as of various dates in August and September 2012 and delivered to the Purchaser prior to the date of this Agreement with respect to all the Real Property (including the real property that the Wichita Terminal is a part of) (the “Current Title Reports”) and that as of midnight at the end of the Business Day prior to the date of this Agreement the Current Title Reports identify no matters of record that are not Permitted Encumbrances other than the title defects identified on Schedule 5.17(a) (“Identified Title Defects”) and the standard title exceptions customarily deleted by a title company upon receipt of a survey or an affidavit of the seller (the “Standard Exceptions”). In addition, the Purchaser shall have the right to object in writing at any time prior to the Closing to any title matters not set forth in the Current Title Reports, including any matters disclosed in amendments to the Current Title Reports and the surveys of the Real Property obtained by the Purchaser; provided that such matters are not shown on a Prior Survey and that a reasonable purchaser of real property would object to such matters as having a potential material and adverse effect on the ownership, use or operation of the subject Owned Real Property or the lessor in the subject Leased Real Property (collectively, “Additional Title Defects”). As used herein, the term “Title Defect” means any Identified Title Defects and Additional Title Defects, subject to the provisions of Section 5.17(b).

(b) If, between the date of this Agreement and three (3) Business Days prior to the Closing Date, the Purchaser identifies any Title Defects, the Purchaser shall provide to Sellers prompt written notice (and in any event, no later than three (3) Business Days prior to the Closing Date) of such Title Defects, which notice shall specify in reasonable detail the nature of such Title Defects. If (i) the Title Company is willing to insure over or provide affirmative insurance against any such Title Defect without any additional cost (unless the Sellers are willing to pay, and pay for at Closing, such additional cost) or (ii) such Title Defect is extinguished prior to or at the Closing by the Sellers, at the Sellers’ sole cost and expense, then the same shall not constitute Title Defects or any breach of the Sellers’ representations hereunder.

(c) The Sellers shall use good faith efforts to cause to be removed or cured, at their expense prior to the Closing, all Title Defects so that no Title Defects appear on the Title Policies. If the Sellers fail to remove any Title Defects or the Sellers are unable to do so, the Purchaser shall nonetheless be required to accept title subject to the uncured Title Defects, subject only to the conditions set forth in Section 6.02; provided, however, that notwithstanding anything to the contrary in this Section 5.17 or elsewhere in this Agreement, the Parent or the Purchaser or any of their respective Affiliates, directors, officers, shareholders, employees, agents or other representatives shall have the right to seek indemnification from the Sellers from and after the Closing under Article VIII in respect of such uncured Title Defects.

-71-

SECTION 5.18. Use of Seller Marks.

(a) Each of the Parent and the Purchaser acknowledges and agrees that, after the Closing, it shall not use the Excluded Marks, and shall remove any such Excluded Marks from the Assets as soon as reasonably practicable, and in any event, no later than sixty (60) days following the Closing Date. Without limiting this Section 5.18(a), promptly after the Closing, the Purchaser shall register all of the railcars using the Purchaser’s unique markings (including railcar identification numbers) and shall cease using the Seller’s unique markings (including railcar identification numbers).

(b) Each of the Sellers acknowledges and agrees that, after the Closing, it shall not use the Acquired Mark, and shall remove any such Acquired Mark from any Excluded Assets as soon as practicable, and in any event, no later than sixty (60) days following the Closing Date.

SECTION 5.19. Use of Software.

(a) The Purchaser shall not use (or allow any of its Affiliates to use) any Installed Software or any proprietary software of the Sellers that is installed on computer systems that are included in the Assets, unless the Purchaser has obtained prior to such use all required licenses and consents (at Purchaser’s sole expense), or otherwise has the right to use such software (including pursuant to Sections 5.03(d) or 5.19(b), the Transition Services Agreement or the Software License Agreement).

(b) Subject to the terms and conditions of this Agreement, the Sellers hereby grant to the Purchaser and its Affiliates that are involved in the operation of the Cement Plants a perpetual, non-exclusive, non-sublicensable and non-transferrable (except as expressly set forth in this clause (b)) royalty-free license to use, copy, modify and adapt the First Level Control interface developed by the Sellers and identified in Schedule 3.12(a), solely in connection with the operation of the Cement Plants and solely on the premises of such Cement Plants. The foregoing license shall be non-assignable and non-transferrable, except to the purchaser of all or substantially all of any Cement Plant at which the First Level Control interface is deployed. This clause (b) does not constitute a transfer or sale of the Sellers’ ownership rights in or to the First Level Control interface, which is an Excluded Asset. THE FIRST LEVEL CONTROL INTERFACE IS BEING PROVIDED ON AN “AS IS” AND “WHERE IS” BASIS, WITHOUT ANY WARRANTY, EXPRESS, IMPLIED OR STATUTORY, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR THE PURCHASER’S PURPOSE, ACCURACY, OR SYSTEM INTEGRATION. THERE IS NO WARRANTY AGAINST INTERFERENCE WITH THE USE OF THE SOFTWARE OR AGAINST INFRINGEMENT.

SECTION 5.20. Air Quality Consent Decree.

The substitution of the Parent and the Purchaser

-72-

for the Defendants as contemplated by this Section 5.20 and paragraph 4(a) of the Air Quality Consent Decree shall be effected pursuant to an amendment to the decree in form and substance reasonably satisfactory to the United States, the Affected States (as defined in the Air Quality Consent Decree), the Defendants, the Parent and the Purchaser.

SECTION 5.21. Certain Environmental Matters.

For a period of five (5) years after the Closing Date, neither the Parent nor the Purchaser shall perform any invasive or destructive sampling or testing at any of the Real Property included in the Assets, unless such sampling or testing is (a) required by any Environmental Law, a Governmental Authority, or the landlord for any Leased Real Property; (b) reasonably necessary in order to avoid a Legal Proceeding threatened by a Governmental Entity or other Person under any Environmental Law; (c) reasonably necessary in order to evaluate, prevent or mitigate an imminent and substantial endangerment to human health or the environment; or (d) undertaken in good faith and in manner consistent with a reasonable and prudent business person (without consideration of the benefit of any indemnification provided by Lafarge) (i) as part of the Parent’s normal operations during the continued use of the plants and facilities (including the performance of capital improvements, operations and maintenance, and reasonable construction and renovation activities) or (ii) as part of an environmental investigation or other due diligence activity (including any Phase I or Phase II assessment) by or in satisfaction of the reasonable requirements of a lender or a bona fide prospective purchaser, assignee, lessee or sublessee of the plants or other facilities.

SECTION 5.22. Wichita Terminal.

The parties shall equally pay all costs and expenses in connection with such partition and subdivision including, without limitation, the cost of a survey. At Closing, the Sellers shall deliver into escrow with the Title Company, to the extent applicable, (i) the documents described in Section 2.02(a)(i), Section 2.02(a)(v), Section 2.02(a)(vii), Section 2.02(a)(x) and Section 2.02(a)(xvii), (ii) an affidavit described in Section 5.02(b)(iii), and (iii) easement agreements for the Easements in recordable form and reasonably acceptable to both Sellers and Purchaser (collectively, the “Wichita Closing Documents”), in each case duly executed and acknowledged, if applicable, with all exhibits completed except for any exhibits setting forth the legal description of the Wichita Terminal. At Closing, Seller and Purchaser shall deliver joint

-73-

escrow instructions to the Title Company instructing the Title Company to hold the Wichita Closing Documents in escrow until the partition and subdivision of the Wichita Terminal from the Wichita Property is completed in compliance with all applicable laws. Promptly following the completion of such partition and subdivision, (i) the Sellers and Purchaser shall instruct the Title Company to insert the legal description of the Wichita Terminal approved by the applicable Governmental Authorities in connection with the partition and subdivision on all applicable Wichita Closing Documents and to record the Deed and the documents creating the Easements, and (ii) in consideration therefor, the Purchaser shall pay to the Sellers an amount in cash equal to the product of (A) $25,000 and (B) the number of acres included in the Wichita Terminal (the “Wichita Conveyance”) by wire transfer of immediately available funds to an account designated by the Sellers, in each case, on the terms and subject to the conditions relating thereto contained in this Agreement . Upon the completion of the Wichita Conveyance, the Wichita Terminal shall, without any further action, be deemed to be an Asset under this Agreement as of such date and the Wichita Terminal Lease Agreement shall automatically terminate. To the extent the Purchaser desires to obtain title insurance (at Purchaser’s sole cost and expense), the provisions of Section 5.17 shall apply as applicable.

The Parent and the Purchaser shall reasonably cooperate with the Sellers in obtaining a release of the bonds or letters of credit that the Sellers have provided to Governmental Authorities or other third parties with respect to the Assumed Liabilities (the “Sellers Bonds or Letters of Credit”), including by providing such Governmental Authorities or third parties bonds or letters of credit in the amounts specified and on terms substantially similar to the relevant Sellers Bonds or Letters of Credit. If such Governmental Authorities or other third parties do not release the Sellers from the Sellers Bonds or Letters of Credit, then for so long as such unreleased Sellers Bonds or Letters of Credit remain outstanding, the Parent shall provide to the Sellers such bonds or letters of credit in favor of the Sellers, in the same amount and on the same terms, as the unreleased Sellers Bonds or Letters of Credit from a third party with the same or higher credit rating as the provider of the unreleased Sellers Bonds or Letters of Credit.

SECTION 5.25. Vehicle, Equipment and Rail Car Leases.

(a) Schedule 5.25 hereto lists each vehicle, piece of equipment, rail car or other Tangible Personal Property that is used exclusively in the conduct of the Business but leased by the Sellers pursuant to a National Contract.

If the Purchaser does not enter into new master Leases in the Purchaser’s name at or prior to the Closing, then the Purchaser may, at its option, (A) purchase such Tangible Personal Property according to the terms required by the Lease between the Sellers and such lessor, (B) treat such Lease as a Retained Contract to which the provisions of Section 1.03 shall apply or (C) implement any other reasonable arrangement acceptable to the Sellers, provided that if, at Closing, no reasonable arrangement that is acceptable to the Sellers is implemented and the Purchaser has not purchased such Tangible Personal Property, then such lease for such Tangible Personal Property shall be deemed a Retained Contract.

(b) If the Sellers receive any invoices for payment of maintenance, property taxes, insurance or loss related to the railcars included in the Assets that are for periods after the Closing, and if the Sellers pay such invoices, then the Purchaser shall promptly reimburse the Seller for any such payments.

If the Purchaser notifies the Sellers within ten (10) days of receipt of such offer that it is interested in acquiring the Fredonia Property or such portion thereof on such terms, the Sellers shall negotiate with the Parent in good faith for the sale thereof to the Parent or a designated subsidiary of the Parent. If (i) the Purchaser fails to notify the Sellers that it is interested in acquiring the Fredonia Property of such portion thereof within ten (10) days of receipt of such offer or (ii) the parties fail to enter into a definitive agreement for the sale of the Fredonia Property or such portion thereof by the end of the thirtieth (30th) day after the Purchaser notified the Sellers that it was interested in acquiring such property, then the Parent shall be deemed to have waived its rights under this Section 5.27 and the Sellers may negotiate and enter into a definitive agreement for the sale of the Fredonia Property or any portion thereof with any third party.

SECTION 5.28. Certain Real Properties.

(a) At the Closing, except to the extent otherwise requested in writing by the Purchaser within thirty (30) days after the date of this Agreement, the Sellers shall deliver, or cause to be delivered, to the Purchaser a Deed with respect to each of the properties described on Schedule 5.28(a) hereto.

If the transactions contemplated by the North Allen Road Agreements do not occur prior to the Closing, then, at the Closing, the Sellers shall, subject to the Sellers obtaining consent from the sellers under the North Allen Road Agreements, assign the North Allen Road Agreements to the Purchaser, and the Purchaser shall assume all rights and obligations of the Sellers under the North Allen Road Agreements. If the Sellers are unable to obtain such consent to assignment prior to Closing, then Sellers shall convey such property pursuant to the provisions of clause (i) and (ii) promptly upon Sellers’ acquisition of such property.

(c) Notwithstanding anything to the contrary in this Agreement, the Sellers make no representations or warranties with respect to, and the indemnification provisions of Section 8.02(a) or Section 8.02(c) shall not apply to the North Allen Road Agreements or any of the properties that may be transferred pursuant to this Section 5.28.

As soon as is reasonably practicable following the Purchaser’s fulfillment of all such pending orders, the Purchaser shall cease all use of the foregoing Mix Designs, and shall delete or destroy (or or cause to be deleted or destroyed) the applicable portions of any books and records containing such Mix Designs.

(i) The Indemnitee shall give the Indemnitor written notice of any such Third-Party Claim, which notice shall specify in reasonable detail (based on the information then available to the Indemnitee) the nature of such Third-Party Claim, promptly following the earlier of the written assertion thereof or the service of any notice of commencement of, or other first legal process relating to, any Legal Proceeding in which such Third-Party Claim is asserted; provided, however, that, if the Indemnitee fails to notify the Indemnitor of a Third-Party Claim promptly as contemplated by this Section 8.04(a)(i), the Indemnitor shall not be relieved of its obligations in respect of such Third-Party Claim except to the extent (and only to the extent) that the Indemnitor is actually and materially prejudiced by such failure.

(ii) Promptly after notification of a Third-Party Claim as contemplated by Section 8.04(a)(i), the Indemnitor may elect to control the defense and, subject to subclause (D) herein, the compromise and settlement of such Third-Party Claim with counsel reasonably acceptable to the Indemnitee; provided, however, that (A) if the Indemnitor fails, within forty-five (45) calendar days after receipt of written notice of such Third-Party Claim, to assume the defense and, subject to subclause (D) herein, the compromise and settlement thereof on the terms set forth in this Section 8.04(a)(ii), the Indemnitee shall have the right to undertake the defense, and subject to subclause (E) herein, the compromise and settlement of such Third-Party Claim on behalf of and for the account and risk of the Indemnitor (subject to the limitations contained in Section 8.05) and the Indemnitor shall pay the reasonable fees and expenses of counsel to the Indemnitee, (B) if, (1) in the reasonable judgment of the Indemnitee, there exists a conflict of interest between the Indemnitee and the Indemnitor with respect to such Third-Party Claim or there are any material defenses available to the Indemnitee that differ from or are in addition to those available to the Indemnitor or (2) the Third-Party Claim would reasonably be expected to result in an injunction or other equitable relief against the Indemnitee that, in the reasonable judgment of the Indemnitee, would be expected to materially and adversely affect the business activities or operations of the Indemnitee, the Indemnitee shall (upon notifying the Indemnitor of its election to do so) have the right to undertake the defense, and subject to subclause (E) herein, the compromise and settlement of such Third-Party Claim with counsel reasonably acceptable to the Indemnitor on behalf of and for the account and risk of the Indemnitor (subject to the limitations contained in Section 8.05) and the Indemnitor shall pay the reasonable fees and expenses of counsel to the Indemnitee, (C) to the extent that the Indemnitee does not have the right to undertake the defense, and subject to subclause (E) herein, the compromise and settlement of such Third-Party Claim, the Indemnitee, if it in its sole discretion so elects, shall be entitled to employ separate counsel and to participate in the defense of such Third-Party Claim, but (1) the fees and expenses of counsel so employed shall

-83-

(except as otherwise provided in subclauses (A) and (B) above) be borne solely by the Indemnitee and (2) the Indemnitee and its counsel shall cooperate with the Indemnitor and its counsel (who, to the extent provided in subclauses (A) and (B) above, shall have the right to control the defense of the Third-Party Claim) in the defense of such Third-Party Claim, (D) the Indemnitor shall not settle or compromise any Third-Party Claim or consent to the entry of any judgment in respect thereof that does not include the grant by the claimant or plaintiff to each Indemnitee of a full and unconditional release from any and all liability in respect thereof and (E) the Indemnitee shall not settle or compromise any Third-Party Claim in any manner, or consent to the entry of any judgment in respect thereof, without the prior written consent of the Indemnitor, which consent will not be unreasonably withheld, conditioned or delayed.

(b) In the event an Indemnitee has an Indemnity Claim against an Indemnitor that is not a Third-Party Claim (a “Direct Claim”), the Indemnitee shall deliver written notice of such Direct Claim, which notice shall specify in reasonable detail (based on the information then available to the Indemnitee) the nature of such Direct Claim, to the Indemnitor promptly after it determines that it is entitled to seek indemnification for such Direct Claim. The failure by the Indemnitee to so notify the Indemnitor hereunder shall not relieve the Indemnitor of its obligations hereunder except to the extent (and only to the extent) that the Indemnitor is actually and materially prejudiced by such failure. If the Indemnitor does not notify the Indemnitee within forty-five (45) calendar days following its receipt of such notice that the Indemnitor disputes its liability to the Indemnitee, such Direct Claim specified by the Indemnitee in such notice shall be conclusively deemed a liability of the Indemnitor and the Indemnitor shall promptly pay the amount of such liability to the Indemnitee on demand or, in the case of any notice in which the amount of the Direct Claim (or any portion thereof) is estimated, on such later date when the amount of such Direct Claim (or such portion thereof) becomes finally determined.

(c) The parties hereto agree that, unless otherwise required by Law, any payment of Losses to an Indemnitee made pursuant to this Article VIII shall be treated as an adjustment to the purchase price paid by the Purchaser for Tax purposes.

SECTION 8.05. Certain Limitations.

Covered Purchaser Indemnity Claims shall accumulate until such time as the aggregate amount of all Losses arising therefrom exceeds the Basket Amount, at which time the Sellers shall be obligated to indemnify the applicable Indemnitees against such Losses, but only to the extent the aggregate amount thereof exceeds the Basket Amount.

-84-

(b) The obligations of the Parent and the Purchaser in respect of Seller Indemnity Claims pursuant to Section 8.03(a) (other than Seller Indemnity Claims in respect of a breach of any Fundamental Representations or that arise from fraud or an intentional and material misrepresentation by or on behalf of the Purchaser or the Parent, which shall not be subject to the limitations set forth in this Section 8.05) (“Covered Seller Indemnity Claims”) shall become operative and effective only if and to the extent that the aggregate amount of all Losses incurred by the applicable Indemnitees arising from Covered Seller Indemnity Claims exceeds the Basket Amount. Covered Seller Indemnity Claims shall accumulate until such time as the aggregate amount of all Losses arising therefrom exceeds the Basket Amount, at which time the Parent and the Purchaser shall be obligated to indemnify the applicable Indemnitees against such Losses, but only to the extent the aggregate amount thereof exceeds the Basket Amount.

(c) The maximum obligation of the Sellers to provide indemnification in respect of Covered Purchaser Indemnity Claims shall not exceed $56,000,000 (the “Cap Amount”).

(d) The maximum obligation of the Parent and the Purchaser to provide indemnification in respect of Covered Seller Indemnity Claims shall not exceed the Cap Amount.

(e) The obligations of the Sellers in respect of any Covered Purchaser Indemnity Claim shall not apply if the amount of Loss incurred by the applicable Indemnitees related to such individual Covered Purchaser Indemnity Claim, together with all related Covered Purchaser Indemnity Claims, totals less than $45,000 (the “De Minimis Threshold”).

(f) The obligations of the Parent and the Purchaser in respect of Covered Seller Indemnity Claims shall become operative and effective only if and to the extent that the amount of Loss incurred by the applicable Indemnitees related to each individual Covered Seller Indemnity Claim or series of related Covered Purchaser Indemnity Claims exceeds the De Minimis Threshold.

(g) Each of the parties hereby acknowledges and agrees that the limitations provided for in Section 8.05(a) through Section 8.05(f) above apply only to Covered Purchaser Indemnity Claims or Covered Seller Indemnity Claims (as the case may be), and do not apply to any other rights to indemnification provided for in this Article VIII, including rights to indemnification against Retained Liabilities or Assumed Liabilities (as the case may be).

(h) Notwithstanding anything to the contrary contained in this Article VIII, the Sellers shall have no obligation to indemnify the Purchaser or its Affiliates under Section 8.02(a) or Section 8.02(c) with respect to any liabilities or obligations arising from the Release of Materials of Environmental Concern to the Environment if such liabilities or obligations constitute Excluded Pre-Closing Environmental Liabilities. In addition, the obligation of the Sellers to provide indemnification pursuant to Section 8.02(a) or Section 8.02(c) with respect to any clean up costs or costs of remediation arising from the Release

-85-

of Materials of Environmental Concern to the Environment shall be limited to costs associated with clean up and remediation actions that are (i) required by applicable Environmental Law or an Order issued by a Governmental Authority, reasonably necessary in order to avoid a Legal Proceeding threatened by a Governmental Entity or other Person under any Environmental Law or reasonably necessary in order to prevent or mitigate an imminent and substantial endangerment to human health or the environment and (ii) taken in good faith and in a manner consistent with the actions that would be taken by a reasonable and prudent business person who owns the applicable Real Property (without consideration of the benefit of any indemnification provided by the Sellers).

(i) Any Losses for which any Indemnitee would be entitled to indemnification under this Article VIII shall be reduced by (i) the amount of insurance proceeds actually received or recovered under any insurance policies for the benefit of such Indemnitee (including the Title Policies) and any cash payments, setoffs or recoupment of any payments recovered by such Indemnitee in respect of such Losses (other than pursuant to any indemnification or similar arrangements that the Indemnitee has purchased following the Closing Date), and (ii) any Tax Benefit. To the extent required by principles of applicable Delaware contract law, each Indemnitee shall use commercially reasonable efforts to mitigate losses for which such Indemnitee is subject to indemnification under this Article VIII. Notwithstanding anything to the contrary in the previous Section, if an Indemnitee believes that coverage for Losses is likely to be available under the Title Policies, such Indemnitee shall use commercially reasonable efforts to pursue any insurance proceeds available to such Indemnitee pursuant to any Title Policies. If, after the Indemnitor has made an indemnification payment to an Indemnitee in satisfaction of its obligations under this Article VIII with respect to any Third-Party Claim or Direct Claim pursuant to this Article VIII, the Indemnitee actually recovers from any third parties amounts in respect of such Losses of the type described in the first sentence of this Section 8.05(i), it shall as promptly as practicable forward to the Indemnitor such amounts (less the full amount of expenses incurred in procuring such recovery, including any applicable deductibles or retentions), but not in excess of the indemnification payment received by the Indemnitee.

(j) For the avoidance of doubt, if any Loss was included as a current liability in the calculation of the Final Working Capital in accordance with the provisions of Section 1.05, the amount of such Loss may not be recovered under this Article VIII, but the amount, if any, of any such Loss that exceeds the amount included as a current liability in the calculation of Final Working Capital may be recovered on and subject to the terms and conditions of this Article VIII.

SECTION 8.06. Exclusive Remedy

From and after the Closing, (a) the provisions of this Article VIII and of Section 1.05(b) shall constitute the exclusive remedy on the part of any party hereto in respect of the subject matter of this Agreement, the Deeds, ’or the transactions contemplated hereby and (b) neither the Parent nor the Purchaser, on the one hand, nor any of the Sellers, on the other, shall seek any indemnification, contribution, repayment or other remedy or recourse directly or indirectly from the other party or parties or their Affiliates with respect to

-86-

the subject matter of this Agreement, the Deeds ’or the transactions contemplated hereby (whether on the basis of a claim sounding in tort, contract, statute or otherwise) outside the provisions of this Article VIII; provided, however, that (i) nothing herein shall limit the right of any party to seek specific performance or injunctive relief in connection with a breach by another party of its obligations under this Agreement or any Ancillary Delivery that occurs after the Closing Date and (ii) nothing herein shall limit the rights of any party under any of the Ancillary Agreements or in respect of a breach of any of the provisions thereof, which rights shall not be subject to or limited by this Article VIII. Notwithstanding the previous sentence or any other provision of this Article VIII, nothing contained in this Article VIII shall be construed to limit any liability on the part of any party hereto for fraud; provided, that in no event shall any party be liable for (A) punitive or exemplary damages, except to the extent that such damages are imposed on or incurred by a party as a result of a Third-Party Claim or (B) any consequential or indirect damages, lost profits, diminution in value, damages to reputation or loss to goodwill except to the extent recoverable under applicable principles of Delaware contract law because they were the reasonably foreseeable consequence of the relevant breach or action and were not occasioned by the special circumstances relating to the Indemnitee.

SECTION 8.07. Investigation

An Indemnitee’s right to indemnification, payment of Losses or other remedies based on any representation, warranty, covenant or obligation of another party contained in or made pursuant to this Agreement, any Deed ’shall not be affected by any investigation conducted by such Indemnitee or any of its representatives or any knowledge acquired (or capable of being acquired) by any such Indemnitee or its representatives, in each case, at any time prior to or after either the date of this Agreement or the Closing Date.

SECTION 10.07. Governing Law.

This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the principles of conflicts of law that would require the application of the laws of another jurisdiction, except to the extent that mandatory principles of conflicts of law require the application of the laws of another jurisdiction wherein any of the Assets are located to determine the validity or effect of the sale, conveyance, transfer, assignment and delivery thereof in accordance with Article I.

SECTION 10.08. Choice of Forum; Waiver of Jury Trial.

(a) All disputes, controversies or Legal Proceedings arising in connection with or commenced by or on behalf of any party to this Agreement in connection with or relating to this Agreement or any of the Ancillary Deliveries or any matters described or contemplated herein or therein (other than with respect to the matters, if any, to be submitted to the Accounting Arbiter in accordance with Section 1.05(b)) shall be instituted in the courts of the State of Delaware.

SECTION 10.09. Severability.

If any provision contained herein shall be held to be invalid, illegal or unenforceable for any reason, the invalidity, illegality or unenforceability thereof shall not affect any other provision hereof, and, to the extent permitted by Law, this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

SECTION 10.10. Specific Performance.

The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with the terms and conditions set forth herein. Accordingly, the parties agree that each of them shall be entitled to seek injunctive relief to prevent breaches of the terms of this Agreement without the necessity of proving actual damages or of posting any bond, and to enforce specifically the provisions hereof, in addition to any other remedy now or hereafter available at law or in equity, or otherwise.

SECTION 10.11. Press Releases.

No party hereto (nor any of its Affiliates) shall issue any press release or other public announcement relating to the subject matter of this Agreement without the prior written approval of (i) in the case of a public announcement by the Sellers (or any of their Affiliates), the Parent or (ii) in the case of a public announcement by the Parent or the Purchaser (or any of their Affiliates), Lafarge; provided, however, that any party hereto may make any such public disclosure to the extent such party reasonably determines such public disclosure to be required by applicable Law or the rules of any stock exchange or by any regulatory body or agency having jurisdiction over it or its Affiliates (but in any such case the disclosing party shall, if practicable in the circumstances, use reasonable efforts to allow the other parties reasonable time to comment on such disclosure in advance of its issuance). The Sellers will consult with the Parent prior to making any announcement relating to the subject matter of this Agreement to the employees of the Business and allow the Parent a reasonable opportunity to review and comment on such announcement prior to the release thereof.
