In order to induce the Sellers, Concrete and Geosolutions to enter into and perform this Agreement and to consummate the transactions contemplated hereby, the Purchaser hereby represents and warrants to the Sellers, Concrete and Geosolutions as follows:

Section 6.1 Organization. The Purchaser is a corporation duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation.

Section 6.2 Authority Relative to this Agreement. The Purchaser has the requisite corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. This Agreement has been duly and validly executed and

delivered by the Purchaser and, assuming the due authorization, execution and delivery hereof by the Sellers, Concrete and Geosolutions, constitutes a valid and binding agreement of the Purchaser, enforceable against it in accordance with its terms, except that such enforceability (a) may be limited by bankruptcy, insolvency, moratorium or other similar laws affecting or relating to enforcement of creditors’ rights generally and (b) is subject to general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity).

Section 6.3 Noncontravention. Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will (a) conflict with or result in any violation of any provision of the certificate of incorporation of incorporation or bylaws (or equivalent governing instruments) of the Purchaser or any of its Subsidiaries, (b) require any consent, approval or notice under, or conflict with or result in a violation or breach of, or constitute (with or without notice or lapse of time or both) a default (or give rise to any right of termination, cancellation or acceleration) under, any of the terms, conditions or provisions of any Contracts of the Purchaser or any of its Subsidiaries or (c) subject to the approvals, filings and consents referred to in Section 6.4, violate any Legal Requirements applicable to the Purchaser or any of its Subsidiaries, except in the case of clauses (b) and (c), with respect to matters that 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 by this Agreement.

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. The Purchaser has delivered to the Seller Representative a true and complete copy of the commitment letter dated December 30, 2005 and related term sheets provided by BNP Paribas for the debt financing of the transactions contemplated by this Agreement (the “Debt Financing Letter”). 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.

(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.

Section 7.1 Conduct of Business of Concrete and Geosolutions.

Nothing in this Section 7.2 shall be interpreted so as to grant to the Purchaser or any of its Representatives the right to perform invasive or subsurface investigations of the properties or facilities of Concrete or its Subsidiaries or Geosolutions.

Section 7.3 Governmental Filings and Consents. Upon the terms and subject to the

conditions of this Agreement, each of the parties hereto shall use all commercially reasonable efforts to take, or cause to be taken, all actions, and to do or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective as promptly as practicable the transactions contemplated by this Agreement, including using all commercially reasonable efforts to effect promptly all required registrations and filings with Governmental Entities, including, without limitation, filings and submissions pursuant to the HSR Act. Any and all filing fees required to be paid in respect of any filings under the HSR Act shall be paid by the Purchaser.

Section 7.4 Public Announcements. The initial press release or releases with respect to the transactions contemplated by this Agreement, as well as the press release or releases with respective to consummation of such transactions, shall be in the form consented to by the Purchaser and the Seller Representative (which consent shall not be unreasonably withheld or delayed), except where such release is required by applicable Legal Requirement. Through the Closing, the Purchaser, on the one hand, and the Sellers, Geosolutions and Concrete, on the other hand, shall not, and shall cause their Subsidiaries and Affiliates not to, issue or cause the publication of any other press release or other announcement with respect to this Agreement or the transactions contemplated hereby without the consent of the other (which consent shall not be unreasonably withheld or delayed), except where such release or announcement is required by applicable Legal Requirement.

Section 7.5 Further Action. Each of the parties hereto shall use all commercially reasonable efforts to take, or cause to be taken, all appropriate action, do or cause to be done all things necessary, proper or advisable under applicable Legal Requirements, and to execute and deliver such documents and other papers, as may be required to carry out the provisions of this Agreement and consummate and make effective the transactions contemplated by this Agreement. If requested by Purchaser, Sellers will use reasonable efforts to obtain cancellation letters from all holders of Concrete Stock Options or Geosolutions Stock Options in connection with the consummation of the transactions contemplated by this Agreement.

Section 7.6 Certain Indemnification. From and after the Closing, the Purchaser will cause each of Concrete and Geosolutions to, and each of Concrete and Geosolutions will, continue to indemnify and hold harmless each present and former director and officer of Concrete and its Subsidiaries and Geosolutions against any Losses incurred in connection with any Action, whether civil, criminal, administrative or investigative, arising out of or pertaining to matters existing or occurring on or prior to the Closing, whether asserted or claimed prior to, on or after the Closing, to the fullest extent that Geosolutions and Concrete would have been permitted under Delaware law and their certificates of incorporation, bylaws or other organizational documents in effect on the date hereof to indemnify such person (including the advancing of expenses as incurred to the fullest extent permitted under applicable Legal Requirements); provided, however, that the person to whom such expenses are advanced must provide an undertaking to Geosolutions or Concrete (as appropriate) to repay such advances if it is ultimately determined by a court of competent jurisdiction (which determination shall have become final) that such person is not entitled to indemnification. 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 costs of such coverage (which shall not exceed $180,000) shall be shared equally by the Sellers, on the one hand, and Purchaser, on the other hand. The Sellers’ portion of such cost shall be considered a Seller Transaction Expense.

Section 7.7 Seller Representative. Each Seller and Qualifying Optionholder hereby designates Investcorp International, Inc. to be the “Seller Representative” to execute any and all instruments or other documents on behalf of the Sellers and the Qualifying Optionholders and to do any and all other acts or things on behalf of the Sellers and the Qualifying Optionholders which the Seller Representative may deem necessary or advisable, or which may be required pursuant to this Agreement or otherwise, in connection with the consummation of the transactions contemplated hereby and the performance of all obligations hereunder at or following the Closing. Without limiting the generality of the foregoing, the Seller Representative shall have the full and exclusive authority to (a) agree with the Purchaser with respect to any matter or thing required or deemed necessary by the Seller Representative in connection with the provisions of this Agreement calling for the agreement of the Sellers and the Qualifying Optionholders, give and receive notices on behalf of all the Sellers and the Qualifying Optionholders, and act on behalf of the Sellers and the Qualifying Optionholders in connection with any matter as to which the Sellers and the Qualifying Optionholders are or may be obligated under this Agreement, all in the absolute discretion of the Seller Representative, (b) make payment to the Purchaser of any amount out of the Working Capital Adjustment Holdback Fund, the Legacy Tax Indemnification Holdback Fund or the Cobra Holdback Fund in order to pay the Purchaser any amounts due to the Purchaser from the Sellers and the Qualifying Optionholders pursuant to Sections 2.6, 10.2 and 7.9, respectively, of this Agreement, to object to any such payment, to agree to negotiate, enter into settlements and compromises of and comply with orders of courts with respect to such claims, all in the absolute discretion of the Seller Representative, and (c) in general, do all things and perform all acts, including without limitation executing and delivering all agreements, certificates, receipts, consents, elections, instructions, and other instruments or documents contemplated by, or deemed by the Seller Representative to be necessary or advisable in connection with, this Agreement. The Sellers and the Qualifying Optionholders shall cooperate with the Seller Representative and any accountants, attorneys or other agents whom it may retain to assist in carrying out its duties hereunder. All decisions by the Seller Representative shall be binding upon all Sellers and the Qualifying Optionholders, and no Seller or Qualifying Optionholder shall have the right to object, dissent, protest or otherwise contest the same. The Seller Representative may communicate with any Seller and the Qualifying Optionholders or any other Person concerning its responsibilities hereunder, but it is not required to do so. The Seller Representative has a duty to serve in good faith the interests of the Sellers and the Qualifying Optionholders and to perform its designated role under this Agreement, but the Seller Representative shall have no financial liability whatsoever to any Person relating to its services hereunder (including any action taken or omitted to be taken), except that it shall be liable for harm which it directly causes by an act of willful misconduct. The Sellers and the Qualifying Optionholders shall indemnify and hold harmless the Seller Representative against any loss, expense (including reasonable attorneys’ fees) or other liability arising out of its services as the Seller Representative under this Agreement, other than for harm directly caused by an act of willful misconduct. 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. The Seller Representative may resign at any time by notifying in writing the Purchaser, the Sellers and the Qualifying Optionholders, provided that at such time the Sellers and the Qualifying Optionholders have named a replacement representative to serve in the Seller Representative’s place.

Information obtained by the Purchaser and its Representatives pursuant to Section 7.2 shall be subject to the provisions of the Confidentiality Agreement. If for any reason this Agreement is terminated prior to the Closing Date, the Confidentiality Agreement shall nonetheless continue in full force and effect in accordance with its terms.

(b) For a period of five years following the Closing Date, the Sellers shall not, and the Sellers shall cause their Affiliates and the respective Representatives of the Sellers and their Affiliates not to, use for their own benefit or divulge or convey to any third party, any Confidential Information; provided, however, that the Sellers or their Affiliates may furnish such portion (and only such portion) of the Confidential Information as the Sellers or such Affiliates reasonably determine they are legally obligated to disclose if: (i) he, she or it receives a request to disclose all or any part of the Confidential Information under the terms of a subpoena, civil investigative demand or order issued by a Governmental Entity; (ii) to the extent legally permissible, he, she or it notifies the Purchaser of the existence, terms and circumstances surrounding such request and consults with the Purchaser on the advisability of taking steps available under applicable Legal Requirements to resist or narrow such request; and (iii) he, she or it exercises his, her or its commercially reasonable efforts to obtain an order or other reliable assurance that confidential treatment will be accorded to the disclosed Confidential Information. For purposes of this Agreement, “Confidential Information” consists of all confidential, proprietary or secret information and data relating to Concrete or its Subsidiaries or Geosolutions or the transactions contemplated hereby including, without limitation, technical information and information pertaining to methods, processes, designs, equipment, customer data and supplier data, utilities data, cost information, transportation information, pricing and operating procedures (other than data or information that is or becomes available to the public other than as a result of a breach of this Section 7.8(b)).

Sellers, Concrete and Geosolutions acknowledge that the Purchaser and its Affiliates may cause one or more information or offering memoranda to be prepared and used in connection with the Purchaser’s financing of the transactions contemplated hereby and the ongoing working capital needs of the Business following Closing. Concrete and Geosolutions shall use their reasonable commercial efforts to provide and to cause the Subsidiaries of Concrete to provide to the Purchaser, its Affiliates and their Representatives access to, and to permit the use of, information reasonably necessary with respect thereto, and to cooperate with the Purchaser, its Affiliates and their Representatives in any reasonable manner in connection with such financing, including providing access to all personnel necessary to consummate such financing, all at such times, in such manner, and upon

such notice as to avoid undue disruption to the Business. Concrete and Geosolutions shall deliver to the Purchaser, its Affiliates and their financing providers in a timely manner and make the management personnel of Concrete, its Subsidiaries and Geosolutions available to execute and deliver or cause to be executed and delivered such agreements, documents, instruments, certificates as to financial and solvency matters and other certificates and consents as are customarily delivered in connection with comparable financings and as may be reasonably requested by the Purchaser, its Affiliates and their financing providers in connection with such financing. Concrete and Geosolutions shall make the management personnel of Concrete, its Subsidiaries and Geosolutions available to participate in road shows and similar presentations to potential lenders and investors and in the preparation of offering memoranda, private placement memoranda and similar documents, provided that such activities do not unduly interfere with the performance by such management personnel of their duties. All out-of-pocket costs and expenses incurred by or on behalf of Concrete, its Subsidiaries and Geosolutions in connection with this Section 7.16 shall be on account of and shall be payable by the Purchaser. Concrete and Geosolutions shall cooperate with the Purchaser, its Affiliates and their Representatives in any reasonable manner to assist the Purchaser in procuring ALTA/ACSM Land Title Surveys-Improved Property (As-Built) of Concrete Real Property or Geosolutions Real Property and written commitments for owner’s policies of title insurance on Concrete Real Property or Geosolutions Real Property (owned and leased), on an American Land Title Association 1992 form (or, if unavailable, equivalent state-specific form).

Section 7.17 Purchaser Financing Efforts. The Purchaser shall use all commercially reasonable efforts to take, or cause to be taken all appropriate action and to do or cause to be done all things necessary, proper or advisable and within its control to cause the funding of the financing contemplated by the Debt Financing Letter to occur at the Closing on terms no less favorable to the Purchaser as the terms set forth therein, or if such financing becomes unavailable for any reason (other than a reason set forth in such letter), to secure alternative financing; provided that this Section 7.17 shall not require the Purchaser to secure alternative financing on terms that are materially less favorable to the Purchaser than those set forth in the Debt Financing Letter.

Section 7.18 Employee Benefits. Except as set forth in Section 7.19 below, at least fifteen days prior to the Closing, the Purchaser shall notify Concrete and Geosolutions of the Concrete Plans and Geosolutions Plans to be terminated effective immediately prior to the Closing, and Concrete and Geosolutions shall take all actions necessary to terminate such Concrete Plans and Geosolutions Plans effective immediately prior to the Closing. The Purchaser shall, and shall cause Concrete, its Subsidiaries and Geosolutions to cause the respective employees of Concrete, its Subsidiaries or Geosolutions after the Closing to be credited with service with Concrete, its Subsidiaries and Geosolutions and their respective predecessors for purposes of eligibility, benefit accrual (except under any defined benefit pension plan or where such crediting would result in duplication of benefits) and vesting under any employee benefit plan or program which is analogous to any Concrete Plan or Geosolutions Plan established, maintained or provided by the Purchaser, Concrete, its Subsidiaries or Geosolutions, as applicable, for the benefit of such employees.

Section 7.19 401(k) Plan. At least fifteen days prior to the Closing Date, the Purchaser shall notify the sponsor of the 401(k) plan in effect for employees of Concrete, its Subsidiaries

and Geosolutions (“Concrete/Geosolutions 401(k) Plan”), that such plan sponsor shall, or shall not, terminate the Concrete/Geosolutions 401(k) Plan effective as of the day before the Closing Date. 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.

Section 7.20 Exclusivity. From and after the date hereof until January 31, 2006, the Sellers, Concrete and Geosolutions shall not, nor shall they permit any of their respective Affiliates to, nor shall they authorize or permit any of their officers, directors or employees or any investment banker, financial advisor, attorney, accountant or other Representative retained by any of them or any of their respective Affiliates to, directly or indirectly through another Person, (a) solicit, initiate or encourage (including by way of furnishing information), or take any other action designed to facilitate any inquiry, offer, proposal or agreement with respect to any Alternative Transaction, (b) participate in any discussions or negotiations regarding any Alternative Transaction, (c) enter into any letter of intent, agreement in principle, memorandum of understanding or binding agreement with respect to any Alternative Transaction, or (d) consummate any Alternative Transaction. Sellers, Concrete and Geosolutions shall and shall cause their respective Affiliates and Representatives to immediately cease and terminate any solicitation, initiation, encouragement, activity, discussion or negotiation with any Person regarding an Alternative Transaction conducted heretofore by any Seller, Concrete, Geosolutions or any of their Affiliates or their Representatives.

Section 7.21 Notification of Certain Matters. The Seller Representative shall give prompt notice to the Purchaser if, prior to the Closing Date, (a) to the knowledge of Concrete, Concrete is served with an Action or (b) to the knowledge of Geosolutions, Geosolutions is served with an Action.

Section 7.22 Section 280G. 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”). Within a reasonable period of time prior to the Closing Date, the Seller Representative shall deliver to the Purchaser and its counsel for review and comment a copy of any documents or agreements necessary to effect this Section 7.22, including but not limited to, any consent form, disclosure statement or waiver.

(a) (i) the representations and warranties contained in Articles III, IV and V shall be true and correct as of the Closing as if made at and as of the Closing (except for representations and warranties that speak as of a specific date prior to the Closing Date which need only be true and correct as of such earlier date); provided, however, that this condition shall be deemed satisfied unless any and all inaccuracies in the representations and warranties contained in Articles III, IV and V, in the aggregate, result in a Material Adverse Effect (ignoring for the purposes of this Section any qualifications by Material or otherwise by material adversity and any materiality qualification or words of similar import contained in such representations or warranties); (ii) Concrete, Geosolutions and the Sellers shall each have performed in all material respects all covenants and agreements herein required to be performed by each of them at or prior to the Closing Date; and (iii) the Purchaser shall have received a certificate from each of Concrete, Geosolutions and the Seller Representative, on behalf of the Sellers, dated as of the Closing Date and signed by an authorized officer of Concrete, Geosolutions and the Seller Representative, respectively, certifying that the conditions specified in this Section 8.1(a) have been satisfied;

(a) the representations and warranties of the Purchaser shall be true and correct in all material respects as of the Closing as if made at and as of such time (other than representations and warranties that speak as of a specific date prior to the Closing Date which only need be true and correct in all material respects as of such earlier date). The Purchaser shall have performed in all material respects all covenants and agreements herein required to be performed by it at or prior to the Closing Date.

(c) the waiting period (and any extension thereof) under the HSR Act applicable to the purchase of the Shares shall have expired or shall have been terminated.

Section 9.1 Termination. This Agreement may be terminated and the transactions contemplated hereby may be abandoned at any time prior to the Closing:

(a) by unanimous written consent of the Purchaser, the Seller Representative, Concrete and Geosolutions;

(b) by the Purchaser, the Seller Representative, on behalf of the Sellers, Concrete or Geosolutions if:

(i) any court or other Governmental Entity of competent jurisdiction shall have issued an order, decree or ruling or taken any other action restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and such order, decree, ruling or other action shall have become final and nonappealable; or

(ii) the Closing shall not have occurred on or prior to January 31, 2006 (the “Termination Date”); provided, however, that the right to terminate this Agreement under this Section 9.1(b)(ii) shall not be available to any party whose failure to fulfill any obligation under this Agreement has been the cause of, or resulted in, the failure of the Closing to occur on or before such date; and provided, further that the Purchaser, if it is not in breach of this Agreement, is using all commercially reasonable efforts to consummate the transactions contemplated hereby and has not satisfied the conditions contained in Section 8.2, or the Seller Representative, if the Sellers are not in breach of this Agreement, are using all commercially reasonable efforts to consummate the transactions contemplated hereby and have not satisfied the conditions contained in Section 8.1, shall have the right, upon notice to the other parties hereto not less than 3 Business Days prior to the Termination Date, to extend the Termination Date until February 8, 2006.

(c) by the Purchaser in the event of a breach by the Sellers, Concrete or Geosolutions of this Agreement that has not been cured within 30 days after the giving of written notice to the Seller Representative or which is incapable of being cured prior to the Termination Date and all such uncured breaches result in a Material Adverse Effect; or

(d) by the Seller Representative, Concrete or Geosolutions in the event of a material breach by the Purchaser of this Agreement, that has not been cured within 30 days after the giving of written notice to the Purchaser or which is incapable of being cured prior to the Termination Date.

Section 9.2 Effect of Termination. In the event that this Agreement is terminated and the transactions contemplated by this Agreement are abandoned pursuant to Section 9.1, written notice of such termination and abandonment shall forthwith be given to the other parties hereto and this Agreement shall terminate and the transactions contemplated hereby shall be abandoned without further action. If this Agreement is terminated as provided herein, no party hereto shall have any liability or further obligation to any other party under the terms of this Agreement; provided, however, that no such termination shall relieve any party for liability resulting from any breach of this Agreement by such party; and provided further that the provisions of this Section 9.2, Article XI and Section 7.8(a) shall survive the termination of this Agreement.

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 Shaw 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 Shaw 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 Shaw 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 Shaw 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.

(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 Shaw Closing Date, and, in the case of a Straddle Period, to the extent apportioned to the period that ends at the close of the Shaw 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 Shaw Closing Date or, with respect to a Straddle Period, to the extent apportioned to the period after the Shaw 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.

(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.

(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 Shaw 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 Shaw 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 Shaw 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 Shaw 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.

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.

Section 11.2 Indemnity by the Sellers. Following the Closing, the Sellers and the Qualifying Optionholders shall severally (and not jointly) indemnify, defend and hold harmless the Purchaser Indemnified Parties from, against and in respect of all Losses resulting from or in connection with any breach of or inaccuracy in any Survival Extended Representations and Warranties contained in Article III or Article IV and each Seller shall severally (and not jointly) (as to himself, herself or itself and not as to any other Seller or Qualifying Optionholder) indemnify, defend and hold harmless the Purchaser Indemnified Parties from, against and in respect of all Losses resulting from or in connection with any breach of or inaccuracy in any Survival Extended Representations and Warranties contained in Article V. No Seller or Qualifying Optionholder shall have any indemnification obligation under this Agreement that aggregates in excess of the proceeds actually received by it for the sale of its Shares or the payment for its Concrete Stock Options or Geosolutions Stock Options pursuant to Article II.

Section 11.3 Amendment and Modification. Subject to applicable Legal Requirements, this Agreement may be amended, modified or supplemented only by a written agreement signed by the Purchaser, on the one hand, and the Seller Representative, on behalf of the Sellers, Concrete and Geosolutions.

Section 11.4 Waiver of Compliance; Consents. 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.

Section 11.6 Expenses. Except as otherwise provided herein, whether or not the transactions contemplated by this Agreement are consummated, all fees, charges and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such fees, charges or expenses.

In this Agreement, unless the context otherwise requires, words in the singular number and the plural number shall each include the singular number and the plural number.

Section 11.10 Partial Invalidity. Wherever possible, each provision hereof shall be interpreted in such manner as to be effective and valid under applicable law, but, in case any one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision or provisions had never been contained herein, unless the deletion of such provision or provisions would result in such a material change as to cause completion of the transactions contemplated hereby to be unreasonable.

Section 11.11 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile shall be as effective as delivery of a manually executed counterpart of this Agreement.

Section 11.14 Jurisdiction; Forum. Any case, proceeding or Action concerning any dispute arising out of or relating to this Agreement must be brought in a court situated in the Borough of Manhattan in the City and State of New York, and each party hereto consents and submits to the jurisdiction of any state or federal court sitting in Borough of Manhattan in the City and State of New York for any such case, proceeding or Action. Each party hereto waives any objection to the laying of venue in such courts and any claim that any such Action has been brought in an inconvenient forum. To the extent permitted by law, any judgment in respect of a dispute arising out of or relating to this Agreement may be enforced in any other jurisdiction within or outside the United States by suit on the judgment, a certified copy of such judgment being conclusive evidence of the fact and amount of such judgment.

Section 11.17 Construction of Certain Provisions. It is understood and agreed that the specification of any dollar amount in the representations and warranties contained in this Agreement or the inclusion of any specific item in the Disclosure Schedule or any other schedules or exhibits attached hereto is not intended to imply that such amounts, or higher or lower amounts, or the items so included or other items, are or are not material, and no party shall use the fact of the setting of such amounts or the fact of the inclusion of any such item herein or therein in any dispute or controversy between the parties as to whether any obligation, item or matter not described herein or therein is or is not material for purposes of this Agreement.
