(c) The Purchaser shall cooperate with the Seller Representative in connection with its review of the Final Adjustment Schedule, including, without limitation, providing the Seller Representative and its accountants reasonable access during business hours to materials (including accountants’ work papers) used in the preparation of the Final Adjustment Schedule.

The Seller Representative shall, within 30 days following its receipt of the Closing Date Balance Sheet and the Final Adjustment Schedule, accept or reject the Purchase Price Adjustment submitted by the Purchaser. If the Seller Representative disagrees with such calculation, it shall give written notice to the Purchaser of such disagreement and any reason therefor within such 30 day period. Should the Seller Representative fail to notify the Purchaser of a disagreement within such 30 day period, the Seller Representative shall be deemed to agree with the Purchaser’s calculation. In the event of such a dispute, the Sellers’ Accountants and the Purchaser’s Accountants shall attempt to reconcile their differences, and any resolution by them as to any disputed amounts shall be final, binding and conclusive on the parties hereto. If the Sellers’ Accountants and the Purchaser’s Accountants are unable to reach a resolution with such effect within 30 days after the receipt by the Purchaser of the Seller Representative’s written notice of dispute, the Sellers’ Accountants and the Purchaser’s Accountants shall submit the items remaining in dispute for resolution to an independent accounting firm of national or regional reputation mutually reasonably acceptable to the Purchaser and the Seller Representative (the “Arbitrator”).

The Purchaser on the one hand, and the Sellers on the other hand, shall bear all costs and expenses incurred by them in connection with such arbitration, except that the fees and expenses of the Arbitrator hereunder shall be borne by the Purchaser and Sellers in the same proportion that the aggregate amount of such remaining disputed items so submitted to the Arbitrator that is unsuccessfully disputed by each such party (as finally determined by the Arbitrator) bears to the total amount of such remaining disputed items so submitted. This provision for arbitration shall be specifically enforceable by the parties and the decision of the Arbitrator in accordance with the provisions hereof shall be final and binding with respect to the matters so arbitrated and there shall be no right of appeal therefrom.

(d) The Final Adjustment Schedule shall be deemed final for the purposes of this Section 2.6 upon the earliest of (x) the failure of the Seller Representative to notify the Purchaser of a dispute within 30 days of the Purchaser’s delivery of the Closing Date Balance Sheet and the Final Adjustment Schedule to the Seller Representative, (y) the resolution of all disputes, pursuant to Section 2.6(c), by the Sellers’ Accountants and the Purchaser’s Accountants or (z) the resolution of all disputes, pursuant to Section 2.6(c), by the Arbitrator.

(e) Upon completion of the Final Adjustment Schedule, the Combined Purchase Price shall be recalculated and the following adjustments made:

(i)

If the Combined Purchase Price calculated using the Net Working Capital shown on the Final Adjustment Schedule is greater than the Combined Purchase Price calculated using the Net Working Capital shown on the Estimate Statement by at least the Designated Amount, the Purchaser shall pay or cause to be paid, the difference to the Sellers, Redeemed Holders and Qualifying Optionholders (in an amount for each such Seller, Redeemed Holder and Qualifying Optionholder determined consistent with Sections 2.2 and 2.5 hereof) by wire transfer in immediately available funds to one or more accounts designated by the Seller Representative. In such

event, the Seller Representative shall distribute all amounts in the Working Capital Adjustment Holdback Fund to the Sellers, Redeemed Holders and Qualifying Optionholders less any amount of expenses incurred by the Seller Representative in connection with the Final Adjustment Schedule;

(ii)

If the Combined Purchase Price calculated using the Net Working Capital shown on the Final Adjustment Schedule is less than the Combined Purchase Price calculated using the Net Working Capital shown on the Estimate Statement by at least the Designated Amount, the Purchaser shall deliver written notice to the Seller Representative specifying the amount of such difference, and the Seller Representative shall, within three Business Days of its receipt of such notice, pay such amount to the Purchaser out of the Working Capital Adjustment Holdback Fund by wire transfer in immediately available funds, it being recognized that Sellers and the Qualifying Optionholders shall remain liable in the event the Working Capital Adjustment Holdback Fund is insufficient to cover the amount of such deficiency; and

(iii)

If any funds remain in the Working Capital Adjustment Holdback Fund after completion of the payment of the adjustments described in Section 2.6(e)(ii) above, the Seller Representative shall distribute all such funds to the Sellers, Redeemed Holders and Qualifying Optionholders, on a pro-rata basis based on the funds committed by each to the Working Capital Adjustment Holdback Fund less any amount of expenses incurred by the Seller Representative in connection with the Final Adjustment Schedule.

Section 6.4 Governmental Approvals. No consent, approval or authorization of, or declaration or filing with, any Governmental Entity on the part of the Purchaser or any of its Subsidiaries that has not been obtained or made is required in connection with the execution or delivery by the Purchaser of this Agreement or the consummation by the Purchaser of the transactions contemplated hereby, other than (a) compliance with the notification and waiting period requirements of the HSR Act and (b) consents, approvals, authorizations, declarations or filings that, if not obtained or made, are not reasonably likely to (i) result in a material adverse effect with respect to the Purchaser and its Subsidiaries, taken as a whole, (ii) impair the ability of the Purchaser to perform its obligations under this Agreement in any material respect or (iii) delay in any material respect or prevent the consummation of any of the transactions contemplated hereby.

Section 6.5 Financing.

Assuming the receipt of the funds contemplated by the Debt Financing Letter, the Purchaser will have available to it at the Closing cash in at least the amount required to make the payments required to be made by it at the Closing and sufficient funds to consummate the transactions contemplated hereby. The Purchaser is not aware of any facts or circumstances that would cause Purchaser to be unable to obtain the financing in accordance with the terms of the Debt Financing Letter.

Section 6.6 No Outside Reliance.

(a) The Purchaser acknowledges and agrees that no other party hereto or any of such other party’s Affiliates or Representatives is making any representation or warranty whatsoever, oral or written, express or implied, as to the accuracy or completeness of any information regarding Concrete, its Subsidiaries or Geosolutions, except as expressly set forth in this Agreement, and that the Purchaser is not relying on any representation or warranty, oral or written, express or implied, made by any other party hereto or such other party’s Affiliates or Representatives, except for the representations and warranties expressly set forth in this Agreement.

(b) In connection with the Purchaser’s investigation of Concrete and its Subsidiaries and Geosolutions, the Purchaser has received certain estimates, projections and other forecasts regarding Concrete and its Subsidiaries and Geosolutions. The Purchaser acknowledges and agrees that there are uncertainties inherent in attempting to make such estimates, projections and other forecasts, that the Purchaser is familiar with such uncertainties and that the Purchaser is taking responsibility for making and has made its own evaluation of the adequacy and accuracy of all estimates, projections and other forecasts so furnished to it (including the reasonableness of the assumptions underlying such estimates, projections and forecasts). Accordingly, none of Concrete, its Subsidiaries, Geosolutions or the Sellers make any representation or warranty with respect to such estimates, projections and other forecasts (including the reasonableness of the assumptions underlying such estimates, projections and forecasts).

Section 6.7 Investment Intent. The Purchaser is acquiring the Shares for its own account for investment purposes only and not with a view to any public distribution thereof in violation of the Securities Act of 1933, as amended or with any intention of selling, distributing or otherwise disposing of the Shares in a manner that would violate the registration requirements of the Securities Act of 1933, as amended.

Section 6.8 Solvency. Assuming all conditions to Closing pursuant to Article VIII hereto have been fulfilled, immediately following the Closing, each of Concrete and Geosolutions will be Solvent. For purposes of this Agreement, “Solvent” when used with respect to Concrete and Geosolutions, means that, immediately following the Closing Date, (i) the amount of the Present Fair Salable Value of each of Concrete’s and Geosolutions’ assets will, as of such date, exceed all of their respective liabilities, contingent or otherwise, determined after giving effect to any savings provisions in guarantees limiting liability to an amount that can be guaranteed without rendering the guarantee voidable under applicable state and federal law, including insolvency laws, as of such date, (ii) each of Concrete and Geosolutions will not have, as of such date, an unreasonably small amount of capital for the business in which they are respectively engaged or will be engaged and (iii) each of Concrete and Geosolutions will be able to pay their respective Debts as they become absolute and mature, taking into account the timing of and the amounts of cash to be received by them and the timing of and the amounts of cash to be payable on or in respect of their indebtedness. The term “Solvency” shall have its correlative meaning. For purposes of the definition of “Solvent”, (A) “Debt” means liability on a “Claim”; and (B) “Claim” means (i) any right to payment, whether or not such a right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed,

legal, equitable, secured or unsecured, determined after giving effect to any savings provisions in guarantees limiting liability to an amount that can be guaranteed without rendering the guarantee voidable under applicable state and federal law, including insolvency laws or (ii) the right to an equitable remedy for breach on performance if such breach gives rise to a payment, whether or not such equitable remedy is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured or unsecured. “Present Fair Salable Value” means the amount that may be realized if the aggregate assets of each of Concrete or Geosolutions, as applicable, (including goodwill) are sold as an entirety with reasonable promptness in an arms length transaction under present conditions for the sale of comparable business enterprises.

Section 6.9 Brokers. No broker, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of the Purchaser for which any Seller would be responsible.

No later than the Closing Date, Purchaser shall purchase “run-off” or “tail coverage” officers and directors liability insurance coverage for the officers and directors of Concrete and Geosolutions, which shall continue until the sixth anniversary of the Closing Date.

The Seller Representative may deduct all out-of-pocket expenses incurred by or on behalf of the Sellers and the Qualifying Optionholders by the Seller Representative from the Holdback Funds. Each Seller and each Qualifying Optionholder hereby agrees that the Purchaser shall have no responsibility for, and hereby releases the Purchaser from, any Liability to such Seller or Qualifying Optionholder and such Seller or

Qualifying Optionholder’s heirs, legal representatives, successors and assigns, for any act or omission of the Seller Representative; provided that the Purchaser shall be entitled to rely upon the identity and notice information for the Seller Representative set forth in Section 11.8 until notice is received by the Purchaser that such information has changed.

Concrete and Geosolutions shall allow each participant in the Concrete/Geosolutions 401(k) Plan who is an employee of Concrete, any of its Subsidiaries or Geosolutions on the Closing Date and qualifies to elect a direct rollover of his or her rolloverable account balance under the Concrete/Geosolutions 401(k) Plan to the 401(k) Plan sponsored by the Purchaser or one of its Affiliates (“Purchaser’s 401(k) Plan”), and Concrete and Geosolutions shall cause the Concrete/Geosolutions 401(k) Plan to deliver to the Purchaser’s 401(k) Plan as soon as practicable after the Closing Date any promissory notes and plan other loan documentation, if any with respect to each participant who elects such rollover.

With respect to each employee of Concrete, its Subsidiaries or Geosolutions who is, or would reasonably be expected to be as of the Closing Date, a “disqualified individual” (as defined in Section 280G(c) of the Code), Sellers shall (i) ensure that any payments made or benefits received by such “disqualified individual” that would otherwise constitute a “parachute payment” with respect to the transactions contemplated by this Agreement (as defined in Section 280G(b)(2) of the Code) shall be exempt from the definition of “parachute payment” by reason of the exemption provided under Section 280G(b)(5)(A)(ii) of the Code, and (ii) prior to the Closing Date, take all actions necessary to so exempt such payments (including, without limitation, obtaining any necessary waivers or consents from such “disqualified individuals”).

ARTICLE X

TAX MATTERS

Section 10.1 General. For the sole purpose of appropriately apportioning any Taxes relating to a Tax year or Tax period that begins before and ends after the ▇▇▇▇ Closing Date (a

“Straddle Period”), such apportionment shall be made assuming that each of Concrete, Geosolutions and SIND had a taxable year that ended at the close of business on the ▇▇▇▇ Closing Date. In the case of property Taxes and other Taxes that apply ratably to a taxable period, the amount of Taxes allocable to the portion of the Straddle Period ending on the ▇▇▇▇ Closing Date shall equal the Tax for the period multiplied by a fraction, the numerator of which shall be the number of days in the period up to and including the ▇▇▇▇ Closing Date, and the denominator of which shall be the total number of days in the period. All other Taxes for any Tax Return that involves a Straddle Period shall be based upon the actual events and transactions that occur within such Straddle Period.

Section 10.2 Tax Indemnification.

(a) The Sellers shall be responsible for and pay and shall indemnify and hold harmless the Purchaser Indemnified Parties from and against all Legacy Tax Liabilities, including losses relating to the payment of any Legacy Tax Liabilities, with respect to Concrete, Geosolutions, SI Corp and SIND for any Tax year or Tax period ending on or before the ▇▇▇▇ Closing Date, and, in the case of a Straddle Period, to the extent apportioned to the period that ends at the close of the ▇▇▇▇ Closing Date under Section 10.1, whether pursuant to the SIND Stock Purchase Agreement or otherwise.

(b) The Purchaser shall be responsible for and shall indemnify and hold harmless the Sellers against all Taxes of each of Concrete and Geosolutions for all Tax years or Tax periods ending after the ▇▇▇▇ Closing Date or, with respect to a Straddle Period, to the extent apportioned to the period after the ▇▇▇▇ Closing Date under Section 10.1.

(c) The indemnification obligations contained in this Section 10.2 shall be the sole remedy available to the Purchaser in connection with Legacy Tax Liabilities, and such indemnification obligations shall survive the Closing and shall continue in full force and effect until 30 calendar days after the applicable statute of limitations, giving effect to extensions thereto, has expired with respect to each such Legacy Tax Liability.

Section 10.3 Tax Contests.

(a) For periods following the Closing, the Purchaser shall promptly notify the Seller Representative in writing of any proposed assessment or the commencement of any Tax Contest or any demand or claim on the Purchaser, its Affiliates, Concrete or Geosolutions that, if determined adversely to the taxpayer or after the lapse of time, could be grounds for indemnification by the Sellers under Section 10.2. Such notice shall contain factual information (to the extent known to the Purchaser, its Affiliates, Concrete or Geosolutions) describing the asserted Tax liability in reasonable detail and shall include copies of any notice or other document received from any taxing authority in respect of any such asserted Tax liability. If the Purchaser fails to give the Sellers prompt notice of an asserted Legacy Tax Liability as required by this Section 10.3, then the Sellers shall not have any obligation to indemnify for any loss arising out of such asserted Legacy Tax Liability, but only to the extent that failure to give such notice results in a detriment to the Sellers.

(b) The Sellers shall have the sole right, at their expense, to control the conduct of such Tax Contest.

(c) The Purchaser and the Sellers agree to cooperate in the defense against or compromise of any claim in any Tax Contest.

Section 10.4 Tax Returns.

(a) The Sellers shall prepare, or cause to be prepared, on a basis consistent with past tax accounting practices all Tax Returns required to be prepared by each of Concrete and Geosolutions pursuant to Section 8.4 of the SIND Stock Purchase Agreement, and shall pay the amount of Taxes shown due on such returns as provided in such Section.

(b) The Purchaser shall timely prepare and file, or cause to be timely prepared and filed, all Tax Returns of each of Concrete and Geosolutions for all Tax periods ending after the ▇▇▇▇ Closing Date, and timely pay, or cause to be paid, when due, all Taxes shown due on such returns.

(c) Neither the Purchaser, Concrete nor Geosolutions (or subsidiaries of any) shall file any amended Tax Return for any period that ends on or before the ▇▇▇▇ Closing Date without the prior written consent of the Seller Representative (which consent is not to be unreasonably withheld or delayed), except as required under applicable Legal Requirements.

Section 10.5 Refunds and Credits. Any refunds, rebates, credits or overpayments of Taxes of either Concrete or Geosolutions for any taxable period ending on or before the ▇▇▇▇ Closing Date shall be for the account of the Sellers. Any refunds, rebates, credits or overpayments of either Concrete or Geosolutions for any taxable period beginning after the ▇▇▇▇ Closing Date shall be for the account of the Purchaser. Any refunds, rebates, credits or overpayments of Taxes of either Concrete or Geosolutions for a Straddle Period shall be equitably apportioned between the accounts of the Sellers and the Purchaser by applying the rules and regulations of the Governmental Entity applicable to such Tax Return. The Purchaser shall, if the Seller Representative so requests and at the expense of the Sellers, the Qualifying Optionholders and the Redeemed Holders, file for and obtain any refunds, rebates, credits or overpayments, or cause either Concrete or Geosolutions to file for and obtain any refunds, rebates, credits or overpayments, to which the Sellers shall be entitled under this Section 10.5. The Purchaser shall permit the Seller Representative to control the prosecution of any such refund claim.

Section 10.6 Cooperation. After the Closing, the Purchaser and the Seller Representative shall promptly make available or cause to be made available to the other, as reasonably requested, and to any taxing authority, all information, records or documents relating to Tax liabilities and potential Tax liabilities relating to either Concrete or Geosolutions for all periods prior to or including the Closing Date and shall preserve all such information, records and documents until the expiration of any applicable statute of limitations or extensions thereof. The Purchaser shall provide to the Seller Representative any Tax information packages, including information relating or received by the Purchasers pursuant to the SIND Stock Purchase Agreement, reasonably requested by the Seller Representative for the Seller Representative’s use in preparing the Tax Returns of SIND, SI Corp, Concrete or Geosolutions.

Section 10.7 Treatment as Purchase Price Adjustment. For Tax purposes, the parties agree to treat all payments made under this Article 10 as Purchase Price Adjustments.

Section 10.8 Payments Net of Tax Benefits. All payments under this Article 10 shall be net of any Tax benefit actually received by the indemnified party or its Affiliates arising in connection with the accrual, incurrence or payment of any Taxes for which indemnification is sought.

ARTICLE XI

MISCELLANEOUS

Section 11.1 Survival of Representations and Warranties. Except for Survival Extended Representations and Warranties, the representations and warranties of Concrete, Geosolutions and Sellers set forth herein shall not survive the Closing. Survival Extended Representations and Warranties and the Purchaser’s representations and warranties set forth in Article VI shall survive without limitation for the maximum period permitted by law.

Any failure of the Purchaser, on the one hand, or the Sellers, Concrete or Geosolutions, on the other hand, to comply with any obligation, covenant, agreement or condition herein may, subject to Section 11.1, be waived by the Purchaser or the Seller Representative (on behalf of the Sellers, Concrete and Geosolutions), respectively, only by a written instrument signed by the party granting such waiver, but such waiver or failure to insist upon strict compliance with such obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure. Whenever this Agreement requires or permits consent by or on behalf of any party hereto, such consent shall be given in writing in a manner consistent with the requirements for a waiver of compliance as set forth in this Section 11.4.

Section 11.5 Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, but neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned by any of the parties hereto without the prior written consent of the Seller Representative and the Purchaser; provided, however, that on or after the Closing, without the consent of the Seller Representative, the Purchaser may pledge, grant a security interest in or assign as collateral all or any portion of its interest in, or rights under, this Agreement to any one or more financial institutions providing all or any portion of the financing of the purchase by the Purchaser of the Shares as contemplated hereby or the refinancing thereof and that upon foreclosure or sale or deed in lieu of foreclosure by or to any such financial institutions, the rights of the Purchaser hereunder may be assigned to any such financial institutions or any purchaser upon such foreclosure or sale or deed in lieu of foreclosure.
