Except as set forth in Schedule 5.16, no Acquired Entity nor any of their ERISA Affiliates sponsors, maintains or contributes to currently, or sponsored, maintained or contributed at any time during the preceding five years, any plan, program, fund or arrangement that constitutes an “employee pension benefit plan.” Each Plan may be terminated by the applicable Acquired Entity or, if applicable, by an ERISA Affiliate at any time without any liability, cost or expense, other than costs and expenses that are customary in connection with the termination of a Plan. None of the Acquired Entities nor any ERISA Affiliate thereof has any obligation to contribute to, or accrue or pay any benefits under, any Plan on behalf of any employee or employees (such as, for example, and without limitation, any individual retirement account or annuity, retiree medical benefits, “excess benefit plan” within the meaning of Section 3(36) of ERISA or any nonqualified deferred compensation arrangements). For purposes of this Agreement, the term “employee pension benefit plan” shall have the meaning given that term in Section 3(2) of ERISA, and the term “ERISA Affiliate” means any corporation or trade or business under common control with an Acquired Entity as determined under Section 414(b), (c), (m) or (o) of the Code. Except as set forth in Schedule 5.16, none of the Acquired Entities or any ERISA Affiliate thereof has sponsored, maintained or contributed to any Plan pursuant to the provisions of any collective bargaining agreement at any time during the preceding five years.

Except as set forth in Schedule 5.16, each Plan that is intended to be “qualified” within the meaning of Section 401(a) of the Code (a “Qualified Plan”) is, and has been during the period from its adoption to the date hereof, so qualified, both as to form and operation and all necessary approvals of Governmental Authorities, including a favorable determination letter or opinion letter, as applicable, as to the qualification under the Code of each of such Qualified Plans and each amendment thereto, have been timely obtained. True and complete copies of all such reports, other documents and favorable determinations with respect to the past three years for each Plan have been provided to

No Acquired Entity nor any ERISA Affiliate maintains, has established or has ever participated in a multiple employer welfare arrangement as described in Section 3(40)(A) of ERISA.

(e) None of the Acquired Entities or any ERISA Affiliate has at any time contributed to or had an obligation to contribute to a Plan subject to either Section 412 of the Code or Title IV of ERISA.

(f) There are no pending or, to the knowledge of the Companies and Shareholders, threatened claims, lawsuits or actions (other than routine claims for benefits in the ordinary course) asserted or instituted against the assets of any Plan or its related trust or against any fiduciary of a Plan with respect to the operation of such Plan. To the knowledge of the Companies and Shareholders, there are no investigations or audits of any Plan by any Governmental Authority currently pending and there have been no such investigations or audits that have been concluded that resulted in any liability to any Acquired Entity or any ERISA Affiliate thereof that has not been fully discharged. None of the Acquired Entities or any ERISA Affiliate thereof has participated in any voluntary compliance or closing agreement programs established with respect to the form or operation of a Plan.

No written notice of any claim, action, suit or proceeding, whether pending or threatened, has been received by any Acquired Entity and, to the knowledge of the Companies and Shareholders, there are no facts or circumstances existing which, with delivery of notice or passage of time or both would be reasonably likely to form the basis of such a claim, action, suit or proceeding. Except to the extent set forth in Schedule 5.17, each Acquired Entity has conducted and is conducting its business in compliance with all Laws applicable to that Acquired Entity, its assets or the operation of its business, except for such instances of noncompliance as would not have, individually or in the aggregate, a Material Adverse Effect.

(v) make any investments in the Capital Stock or securities convertible into, or exchangeable or exercisable for, any Capital Stock of any other Entity or in any indebtedness of any other Person;

(ix) (A) adopt, establish, amend or terminate any Plan or (B) take any discretionary action, or omit to take any contractually required action, if that action or omission could either (1) deplete the assets of any Plan or (2) increase the liabilities or obligations under any such Plan;

(xiv) commit breaches of Listed Agreements that in the aggregate are material to the Acquired Business or amend or terminate any material agreement of the Acquired Business or any of its Governmental Approvals; or

(c) Prior to the Closing Date, the Companies will (i) satisfy any requirement for notice of the transactions this Agreement contemplates under applicable collective bargaining agreements and (ii) provide Buyer with proof that any required notice has been sent.

(d) Each of the Companies and each Shareholder agrees that, from the date hereof and until the first to occur of the Closing or the termination of this Agreement in accordance with Article XII, neither of the Companies nor either Shareholder, nor any of their respective officers or directors will, and each of the Companies and each Shareholder will direct and use their best efforts to cause each of their respective representatives not to, initiate, solicit or encourage, directly or indirectly, any inquiries or the making or implementation of any proposal or offer with respect to a merger, acquisition, consolidation or similar transaction involving, or any purchase of all or any significant portion of the assets or any equity securities of, any Acquired Entity (any such proposal or offer being an “Acquisition Proposal”) or engage in any activities, discussions or negotiations concerning, or provide any confidential information respecting, the Acquired Business or any of the Acquired Entities to, or have any discussions with, any Person relating to an Acquisition Proposal or otherwise facilitate any effort or attempt to make or implement an Acquisition Proposal. Each of the Companies and each Shareholder will: (i) immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons conducted heretofore with respect to any of the foregoing, and each will take the steps necessary to inform the Persons to which the first sentence of this Section 7.02(d) refers of the obligations undertaken in this Section 7.02(d); and (ii) notify Buyer immediately if any such inquiries or proposals are received by, any such information is requested from or any such discussions or negotiations are sought to be initiated or continued with either of the Companies or either Shareholder.

7.03 Notification of Certain Matters. From the date hereof and until the Closing, Shareholders will give prompt notice to Buyer of (i) the existence or occurrence of each condition or state of facts which, to the knowledge of the Companies and Shareholders, will cause any representation or warranty of Shareholders or the Companies contained herein to be

untrue or incorrect in any material respect on the Closing Date and (ii) any material failure of a Shareholder or any Acquired Entity to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by that party hereunder as of the Closing Date. From the date hereof and until the Closing, Buyer will give prompt notice to Shareholders of (i) the existence or occurrence of each condition or state of facts which will or reasonably could be expected to cause any representation or warranty of Buyer contained herein to be untrue or inaccurate on or prior to the Closing Date and (ii) any material failure of Buyer to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder. The delivery of any notice under this Section 7.03 will not be deemed to (i) modify the representations or warranties herein of the party delivering that notice, or any other party, (ii) modify the conditions set forth or referred to in Article IV or (iii) limit or otherwise affect the remedies available hereunder to the party receiving that notice.

7.04 Bonuses. Within 10 days following the determination of the Consideration Adjustment or 75 days following the Closing, whichever shall occur first, Redi-Mix, L.P. and ▇▇▇▇▇▇ Enterprises, L.P. (the “Partnerships”) will pay bonuses to the employees listed on Schedule 7.04 relating to the period through the Closing Date, with the aggregate amount of such bonuses, as well as the amount to be paid to each of them, to be determined in the reasonable discretion of Shareholders but not to exceed 50% of the pre-tax earnings generated by the Acquired Entities during the period from January 1, 2006 through the Effective Time (determined in accordance with GAAP, and after giving effect to the accrual of the obligation to pay such bonuses) (such limitation being the “50% Pre-Tax Earnings Limitation”); provided, however, that if the determination of the aggregate amount of such bonuses is made prior to the determination of the Consideration Adjustment, such determination shall be made using an estimate of the 50% Pre-Tax Earnings Limitation prepared by Shareholders and approved by Buyer (which approval shall not be unreasonably withheld). To the extent the bonuses paid in accordance with this Section 7.04 exceed the 50% Pre-Tax Earnings Limitation, as determined from the Effective Date Financial Statements following final determination of the Consideration Adjustment, if any, Shareholders shall pay to the applicable Partnership the amount of such excess within 10 days of receipt of the final determination of the Consideration Adjustment, and the obligation of the Shareholders to make such payment shall be joint and several and shall not be subject to any indemnification threshold or limitation set forth in Article VIII. Notwithstanding the foregoing: (i) with respect to the individuals listed on the bonus exhibit to Schedule 7.04, payment of amounts in accordance with this Section 7.04 shall be contingent upon the execution of a written consent of the partners in each Partnership; and (ii) the execution of any such consent is not a condition of Closing. The Acquired Entities will use their reasonable best efforts to cause each employee that is to receive a bonus to execute, as a condition to receipt of such bonus, a release of the Shareholders and their Affiliates in the form set forth in Schedule 7.04 and heretofore approved by the Shareholders and each such employee.

7.05 Public Announcements. Prior to the Closing, Buyer on the one hand and Shareholders on the other hand will consult with and obtain the approval (not to be unreasonably withheld or delayed) of the other party before issuing any press release or otherwise making any public statements with respect to this Agreement and the transactions it contemplates; provided, however, that no such consultation or approval shall be required where the release or announcement is required by applicable law; and provided, further, that either Buyer or Shareholders may respond to inquiries by the press or others regarding the transactions this

Agreement contemplates as long as such responses are consistent with and limited to the party’s previously issued press releases.

7.06 Title Assurance. Following the Closing Date, Shareholders shall provide Buyer at Buyer’s expense with such reasonable cooperation as Buyer may request in connection with Buyer’s acquisition of extended coverage policies of title insurance insuring title to the Land to be in the applicable Acquired Entities, subject only to Permitted Encumbrances. Buyer shall pay all of the premiums and associated out-of-pocket costs relating to such title policies.

7.07 Expenses. Buyer will pay the fees, expenses and disbursements of Buyer and its agents, representatives, accountants and counsel incurred in connection with the execution, delivery and performance of this Agreement and any amendments hereto. Shareholders will pay their fees, expenses and disbursements and those of their and the Acquired Entities’ agents, representatives, financial advisors, accountants and counsel incurred in connection with the execution, delivery and performance of this Agreement and any amendments hereto and the consummation of the transactions contemplated hereby. Shareholders will also pay any costs associated with business brokers or other advisors engaged by Shareholders or any Acquired Entity.

7.08 Repayment of Related-Party Indebtedness. Prior to or at the Effective Time, (a) Shareholders shall repay to each Acquired Entity all amounts outstanding as advances to or receivables from Shareholders, each of which advances or receivables is specifically reflected in Schedule 5.25, and (b) each Acquired Entity shall repay all amounts outstanding under loans to that Acquired Entity from Shareholders, each of which loans is specifically reflected in Schedule 7.08.

7.09 Governmental Filings.

(a) Buyer, the Acquired Entities and Shareholders shall cooperate with one another and assist each other:

(i) in determining whether any action by or in respect of, or filing with, any Governmental Authority is required, or any actions, consents, approvals, or waivers are required to be obtained from any Governmental Authority in connection with the consummation of the transactions contemplated by this Agreement; and

(ii) in taking such actions or making any such filings, furnishing information required in connection therewith and seeking timely to obtain any such actions, consents, approvals or waivers.

Each of Buyer, the Acquired Entities and Shareholders, as appropriate or required, shall: cooperate with the other party or parties in connection with any filings or submissions to, or conferences with, any Governmental Authorities with respect to the Acquisition; keep the other party reasonably and promptly informed of all developments and communications with any Governmental Authority with respect to the Acquisition; provide copies of all documents and correspondence filed or submitted to any Governmental Authority with respect to the Acquisition to the non-filing party or parties and its or their advisors prior to filing and, if requested, accept all reasonable modifications suggested in connection therewith; not participate in any meeting

with any Governmental Authority concerning the Acquisition unless it consults with the other party or parties in advance (to the extent permitted by such Governmental Authority and subject to the confidentiality provisions of this Agreement); and resist vigorously, at their respective cost and expense, any assertion that the transactions contemplated herein constitute a violation of any of the antitrust laws, all to the end of expediting consummation of the transactions contemplated herein; provided, however, that Buyer shall not be required to (i) institute or defend legal proceedings or to limit, curtail or divest of any of its existing businesses or the business it conducts with any of its customers in order to obtain any such approval or (ii) restructure the transactions contemplated hereby in any material respect.

7.10 Future Cooperation; Tax Matters.

(a) Shareholders and Buyer shall each deliver or cause to be delivered to the other following the Closing such additional instruments as the other may reasonably request for the purpose of fully carrying out this Agreement. Shareholders and Buyer will cooperate and use their reasonable best efforts to have the present and future officers, directors and employees of the Acquired Entities cooperate with Shareholders and Buyer at and after the Closing in furnishing information, evidence, testimony and other assistance in connection with any actions, proceedings, arrangements or disputes of any nature with respect to matters pertaining to all periods prior to the Closing. Buyer will provide Shareholders with access to such of its books and records as may be reasonably requested by Shareholders in connection with federal, state and local tax matters relating to periods prior to the Closing. The party requesting cooperation, information or actions under this Section 7.10 shall reimburse the other party for all reasonable out-of-pocket costs and expenses paid or incurred in connection therewith, which costs and expenses shall not, however, include per diem charges for employees or allocations of overhead charges.

(b) Following the Closing, Shareholders shall pay to Buyer (i) the amount of all Pre-Closing Taxes to the extent such Taxes were not paid by the Acquired Entities prior to Closing or reflected on the balance sheet included in the Effective Date Financial Statements and (ii) all Taxes of any such Shareholder or any Affiliate thereof (other than an Acquired Entity) that are collected by any Tax Authority from Buyer, any Affiliate of Buyer or any Acquired Entity.

(c) Following the Closing, Shareholders shall be responsible for the preparation of all Tax Returns of an Acquired Entity covering the period from the beginning of each Acquired Entity’s current Tax year through the Closing Date, and shall be responsible for all costs and expenses incurred in connection with the preparation of such Tax Returns. To the extent the Shareholders have any liability for Pre-Closing Taxes pursuant to Section 7.10(b) with respect to such Tax Returns, the Shareholders shall pay such Taxes to Buyer; and the Taxes on such Tax Returns shall be paid by the Acquired Entities. Shareholders shall not make any irrevocable elections on such Tax Returns that may impact future Tax Returns of Buyer or any of the Acquired Entities without the prior written consent of Buyer (which consent Buyer may withhold in its sole discretion if such election is inconsistent with past elections (or determinations not to elect) of the applicable Acquired Entity or Acquired Entities). Shareholders shall not cause an Acquired Entity to file any Tax Return without the prior written consent of Buyer, which consent shall not be unreasonably withheld or delayed. Buyer will cooperate with Shareholders in their preparation of all Tax returns covering the period from the beginning of each Acquired Entity’s

current Tax year through the Closing Date. Buyer shall prepare and timely file all Tax Returns in respect of an Acquired Entity with respect to taxable periods that begin before and end after the Tax Effective Date (“Straddle Period Returns”). To the extent that Shareholders have any liability for Pre-Closing Taxes pursuant to Section 7.10(b) on any Straddle Period Return, such Straddle Period Return shall be subject to the written approval of Shareholders, which approval shall not be unreasonably withheld or delayed; provided that such consent may not be withheld (and will be deemed to have been provided) if such Straddle Period Return is prepared in a manner consistent with past practices. The portions of the Straddle Period Returns relating to taxable periods ending on or before the Tax Effective Date shall reflect the practices of the Acquired Entity in respect of the Tax Returns for prior periods.

(d) Following the Closing, Shareholders shall be entitled to any Tax refunds payable with respect to (i) any period ending on or before the Tax Effective Date and (ii) the portion of any Straddle Period ending on the Tax Effective Date, in each case only to the extent such refunds are not reflected on the balance sheet included in the Effective Date Financial Statements and do not arise from tax elections or tax positions taken by Buyer on or after the Closing Date or results of operations after the Tax Effective Date. Buyer will cooperate with Shareholders in filing any Tax Return required to claim any such refund provided that (i) Shareholders shall incur all costs and expenses of filing such Tax Returns and (ii) the filing of any such Tax Return shall not negatively impact the Tax Returns of Buyer.

7.11 Further Assurances. Subject to the terms and conditions of this Agreement, each of Buyer, Shareholders and the Acquired Entities shall use reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement, including providing information and using reasonable efforts to obtain all necessary exemptions, rulings, consents, authorizations, approvals and waivers to effect all necessary registrations and filings and to lift any injunction or other legal bar to the transactions contemplated hereby as promptly as practicable.

7.12 Adjustments to Consideration Paid at Closing.

(a) As soon as practicable after the Closing Date, Buyer and the Acquired Entities (with the reasonable cooperation of and input from Shareholders) shall cause to be prepared and delivered to Shareholders a consolidated balance sheet of the Acquired Business as of the Effective Time and a consolidated income statement of the Acquired Business for the period from (and including) January 1, 2006 through the Effective Time, in each case prepared from the books and records of the Acquired Entities in conformity with GAAP (the “Effective Date Financial Statements”). Within 10 days of the delivery of the Effective Date Financial Statements, Buyer shall deliver to Shareholders a schedule (the “Consideration Adjustment Schedule”) setting forth the amount of each of the Final Dividend Adjustment, the Final Interest-Bearing Debt Adjustment, the Final Pre-Closing Earnings Adjustment and the resulting net Consideration Adjustment.

(b) The Effective Date Financial Statements and Consideration Adjustment will be final and binding on the parties hereto unless, within 10 days following Buyer’s delivery of the calculation of the Consideration Adjustment, Shareholders notify Buyer in writing that

Shareholders disagree with all or any portion of the Effective Date Financial Statements and/or the Consideration Adjustment. If Shareholders and Buyer cannot mutually resolve any such disagreement within 15 days after the receipt by Buyer of Shareholders’ notice of disagreement, then Shareholders and Buyer shall submit the dispute to a mutually agreeable certified public accounting firm (the “Accountant”) within 10 days after the end of such 15-day period. If Shareholders and Buyer are unable to agree upon such an accounting firm within such 10-day period, then Shareholders and Buyer shall select a “Big Four” accounting firm (excluding PricewaterhouseCoopers LLP) by lot, which accounting firm shall act as the Accountant. Shareholders and Buyer shall request that the Accountant audit the Effective Date Financial Statements and provide a computation of the Consideration Adjustment within 60 days thereafter, and this computation will be final and binding upon the parties hereto, and the payment of the Consideration Adjustment shall be made within five days of delivery by of this computation by the Accountant. In the event Shareholders and Buyer submit any unresolved objections to an Accountant for resolution as provided in this Section 7.12, Shareholders and Buyer will each pay one half of the fees and expenses of the Accountant.

(c) If the Consideration Adjustment (as finally determined in accordance with Section 7.12(b)) is a positive number, then Buyer shall pay that amount to Shareholders, in accordance with their respective shares set forth in Schedule 7.12(c), in cash within 10 days after the final determination thereof in accordance with Section 7.12(b). If the Consideration Adjustment (as finally determined in accordance with Section 7.12(b)) is a negative number, then Shareholders shall pay, in accordance with their respective shares set forth in Schedule 7.12(c), that amount to Buyer in cash within 10 days after the final determination thereof in accordance with Section 7.12(b).

7.13 Limitation on Future Distributions by Shareholders. In order to ensure the ability of Shareholders to satisfy any indemnification obligations that may become due from them to Buyer pursuant to the provisions of Article VIII, each Shareholder agrees that, from the Closing through the fifth anniversary of the Closing Date, without the prior written consent of Buyer, which shall not be unreasonably withheld, such Shareholder shall not authorize, pay or make any payment of a dividend or other distribution to its shareholders or other owners or repurchase any of its Capital Stock (any such dividend, distribution or repurchase being a “Shareholder Distribution”) if, at the time of declaration or payment of such Shareholder Distribution, such Shareholder is or would be (after giving effect to such Shareholder Distribution) insolvent under any applicable fraudulent conveyance or transfer law. Without limiting the foregoing covenant: (i) from the Closing through the second anniversary of the Closing Date, without the prior written consent of Buyer, which shall not be unreasonably withheld, neither Shareholder shall authorize, pay or make one or more Shareholder Distributions that would cause such Shareholder to have net cash or fair value of net tangible assets (that are not Encumbered) in an amount less than 20% of the Consideration received thereby; (ii) from the Closing through the fifth anniversary of the Closing Date, without the prior written consent of Buyer, which shall not be unreasonably withheld, neither Shareholder shall authorize, pay or make one or more Shareholder Distributions that would cause such Shareholder to have net cash or fair value of net tangible assets (that are not Encumbered) in an amount less than 5% of the Consideration received thereby; and (iii) without the prior written consent of Buyer, which shall not be unreasonably withheld, in no event shall either Shareholder authorize, pay or make any Shareholder Distribution after the Closing Date at the time any indemnification

claim or claims made in good faith by Buyer or any other Indemnified Party against either or both Shareholders pursuant to Article VIII is pending if, as a result of such Shareholder Distribution, the net cash or fair value of net tangible assets (that are not Encumbered) would be less than the aggregate amount reasonably determined by the Shareholders after consultation with counsel to be at issue pursuant to such indemnification claim or claims. Because of the fact that a breach of the foregoing covenants would diminish the value of the assets of Shareholders available to satisfy their indemnification obligations under this Agreement, and because of the immediate and irreparable damage that would be caused to Buyer for which Buyer would have no other adequate remedy, since monetary damages alone may not be an adequate remedy, each Shareholder agrees that the foregoing covenant may be enforced against such Shareholder by, without limitation, injunctions, restraining orders and other equitable actions.

7.14 Pre-Closing Loan.

(a) So long as none of the Companies or Shareholders are in breach of any of their obligations hereunder or the documents executed in connection herewith (the “Loan Documents”) and subject to the other conditions described in this Agreement, Atlas Investments, Inc. may request that Buyer provide a loan to Atlas Investments, Inc. not more than two days prior to the scheduled date of the Closing in a principal amount of not more than $33,000,000 (the “Loan”). The Loan shall be evidenced by a promissory note, in substantially the form of Exhibit C, dated the date the Loan is made in the original principal amount of the Loan advanced and made payable to the order of Buyer. The Loan shall be scheduled to mature on the earlier of the date of the Closing and the second day after the Loan is made and the principal amount thereof shall bear interest at 5% per annum, accruing from the date the Loan is made; provided, that in the event that the Closing does not occur as scheduled as a result of the failure of a condition set forth in Section 4.03 or the failure of Buyer to obtain the Financing, interest shall not be deemed to accrue for the period that the Loan is outstanding. All accrued and unpaid interest and principal of the Loan shall be due and payable on the maturity date of the Loan. The Loan and the obligations of the Shareholders and Companies with respect to this Agreement and the Loan Documents shall be secured by a first priority security interest on all of the Capital Stock (and related rights) of Alberta, Alliance, Atlas Investments, Inc., Redi-Mix Management, Inc., Redi-Mix GP, LLC and ▇▇▇▇▇▇ Enterprises Management, Inc., pursuant to a pledge and security agreement in substantially the form of Exhibit D. The conditions to the Loan shall include such conditions as are reasonably requested by Buyer, including (i) the receipt of a certificate of the Shareholder and Companies stating that at such time and after giving effect to the Loan and the transactions contemplated thereby all representations of the Shareholders and Companies contained herein and the Loan Documents are and shall be true and correct and that no breach of the obligations of the Shareholders or Companies has occurred under this Agreement and the Loan Documents, (ii) the execution and delivery of Loan Documents, together with stock powers satisfactory to Buyer, and (iii) the receipt of evidence reasonably satisfactory to Buyer as to the enforceability of the note, the loan agreement, pledges and other Loan Documents, the validity, perfection and priority of such security interests and the ability of the parties thereto affiliated with Alberta and Atlas Investments, Inc. to enter into the transactions contemplated by the Loan Documents.

(b) Buyer acknowledges that, and the promissory note evidencing the Loan and the related pledge and security agreement shall permit that, the proceeds of the Loan may be used by

Atlas Investments, Inc. to effect a distribution to Alberta and by Alberta to effect a distribution to Atlas with respect to the outstanding shares of preferred stock of Alberta (the “Alberta/Atlas Investments Distribution”).

(c) In the event that the Closing shall occur prior to repayment of the Loan, (i) Buyer shall reduce the Consideration to be paid as of the Closing by the amount of the Loan and (ii) in the event the Loan is used to effect the Alberta/Atlas Investments Distribution, each party hereto agrees to disregard for United States federal income Tax purposes the Loan and the Alberta/Atlas Investments Distribution and to treat the proceeds of the Loan as a payment of a portion of the consideration paid by Buyer to Shareholders in respect of the Companies Capital Stock; provided that Section 5.18 (as to representations by Shareholders as to Taxes) shall for all purposes of this Agreement be deemed to include a representation by Shareholders that such treatment is proper for such purposes and for all other United States Tax purposes so that the Shareholders shall be responsible pursuant to the other provisions hereof for any failure of such representation to be true and without loss of generality shall so be responsible for any Tax (such as a withholding Tax) that is imposed upon Alberta, Atlas or any other Acquired Entity by reason of one or both of the Loan and Alberta/Atlas Distribution not properly being disregarded for United States federal income tax purposes or for any other United States Tax purpose.

7.15 Financing Commitments. Buyer will use reasonable best efforts to enter into definitive agreements with respect to and obtain the Financing prior to Closing. At Shareholders’ request, Buyer shall keep Shareholders reasonably informed with respect to all material activity concerning the status of the Financing and shall give Shareholders prompt notice of any material adverse change with respect to such Financing. Buyer will furnish correct and complete copies of such definitive agreements to the Shareholders promptly upon their execution.

ARTICLE VIII
INDEMNIFICATION

8.01 Survival of Representations and Warranties and Covenants.

(a) Notwithstanding any investigation at any time made by or on behalf of any party hereto, the representations and warranties set forth in Article V and Article VI and in any certificate delivered in connection with this Agreement with respect to any of those representations and warranties shall survive the Closing for a period of two years from the Closing Date (the “Expiration Date”), except that (i) the representations and warranties set forth in Sections 5.11, 5.16 and 5.18 hereof shall survive until such time as the applicable statute of limitations period has run, which shall be deemed to be the Expiration Date for Sections 5.11, 5.16 and 5.18, as the case may be, and (ii) the representations and warranties in Section 5.03 shall survive indefinitely and shall not expire. Any representation or warranty as to which a party has given notice in writing describing in reasonable detail the alleged breach prior to the applicable Expiration Date shall survive until the earlier of payment in full or judicial termination of any claim relating thereto. The respective parties shall remain liable after the Expiration Date for breaches of the representations and warranties set forth in Article V and Article VI, provided such breaches are asserted in good faith by notice in writing and in reasonable detail to the alleged breaching party prior to the Expiration Date.

(b) The covenants set forth in Article VII, other than in Sections 7.07, 7.10, 7.11 and 7.12, will terminate immediately following the Closing.

8.02 Indemnification by Shareholders.

(a) Subject to Section 8.06 and Section 8.07, Shareholders covenant and agree that they will jointly and severally (without any right of indemnification or contribution from any of the Acquired Entities) indemnify, defend, protect and hold harmless Buyer and its officers, directors, employees, stockholders, agents, representatives and Affiliates, at all times from and after the date of this Agreement from and against all Losses incurred by any of such indemnified Persons, whether asserted prior to, at or after the Closing, arising out of or resulting from any facts, circumstances or events occurring (or not occurring) on or before the Closing Date relating to: (i) any breach of the representations and warranties of Shareholders or the Companies set forth herein or in the Schedules attached hereto (it being understood that, notwithstanding anything to the contrary contained in this Agreement, to determine the amount of Losses arising from an inaccuracy or breach of a representation or warranty of Shareholders (but not to determine whether or not such a breach has occurred), such representation or warranty shall be read as if it were not qualified by materiality); (ii) any breach or nonfulfillment of any covenant or agreement on the part of Shareholders or the Companies under this Agreement; (iii) all transfer Taxes arising from the transactions this Agreement contemplates (including all transfer and other Taxes arising from the Alberta/Atlas Investments Distribution, whether paid or payable by any of the Acquired Entities or any Shareholder) and all other Taxes for which a Shareholder is liable under this Agreement; (iv) any of the matters referred to on Schedule 8.02, to the extent such Losses exceed any specific reserves for such Losses reflected in the balance sheet included in the Effective Date Financial Statements, subject to any applicable limitation with respect thereto set forth in Schedule 8.02; or (v) any condition, circumstance or state of facts set forth in Schedule 5.11 or any other existing condition, circumstance or state of facts in existence on or before the Closing Date which Section 5.11 calls for disclosure in Schedule 5.11 (the “Existing Environmental Conditions”) to the extent such Losses exceed any specific reserves for such Losses reflected in the balance sheet included in the Effective Date Financial Statements; provided, however, that, except with respect to the completion of any Remediation Activities (as defined below) with respect to any of the Existing Environmental Conditions initiated at any time prior to the Closing Date: (A) any responsibility of Shareholders for Losses with respect to any investigation, removal, abatement, response, cleanup or groundwater monitoring activities (collectively, “Remediation Activities”) with respect to any of the Existing Environmental Conditions in connection with the indemnification provided pursuant to this clause (v) shall apply only to the extent such Remediation Activities are required under any applicable Environmental Law that is in effect on the date hereof or by directive or order of any Governmental Authority having jurisdiction; and (B) Buyer agrees that neither it nor any of the Acquired Entities may seek indemnification pursuant to this clause (v) with respect to any previously unreported Environmental Condition the discovery or existence of which Buyer or an Acquired Entity reports to any Governmental Authority after the Closing Date unless Buyer or an Acquired Entity determines in good faith that such a report is required under applicable Environmental Law.

(b) If Atlas Investments, Inc., Alberta, Buyer or any Person who is then an Affiliate of Buyer and who is an Indemnified Person receives any claim from the Internal Revenue

Service or other Governmental Authority as to the payment of any withholding Tax or other Tax by reason of the Loan or the Alberta/Atlas Distribution (or both), then, notwithstanding any provision hereof to the contrary, the Shareholders shall promptly either (i) pay the amount of such claim to such Indemnified Person who shall pay the amount so received to the Internal Revenue Service or such Governmental Authority, as the case may be, or (ii) provide security that is satisfactory to Buyer in its reasonable judgment for the payment of such claim and any interest or additional Tax that may accrue thereafter on such claim during the next two years (and shall, each six months thereafter, increase the amount that is so provided as security so that an amount that is equal to interest or additional Tax on such for two years after such date is also so held); provided, however, that if Atlas Investments, Inc., Alberta, Buyer or any Person who is then an Affiliate of Buyer pays any such amounts (including during the pendency of any dispute with the Internal Revenue Service or other Governmental Authority relating thereto and whether or not it is obligated to do so), then Shareholders shall make prompt payment to Buyer or any Affiliate of Buyer designated by Buyer of the amount so paid to the Internal Revenue Service or other Governmental Authority. If the Shareholders breach their obligations pursuant to this Section 8.02(b), then Buyer may in its sole discretion pay (or cause to be paid) the amount of such claim and Buyer (or any Affiliate of Buyer that makes such payment) shall then be entitled to full indemnification from Shareholders hereunder as to the amount so paid and Shareholders shall have no right to delay payment thereof. In the event the Shareholders pay any amounts pursuant to this Section 8.02(b) either directly to the Internal Revenue Service or other Governmental Authority, or to Atlas, Alberta, Buyer or any Person who is then an Affiliate of Buyer to reimburse any such party for a payment to the Internal Revenue Service or other Governmental Authority, Buyer and its Affiliates will cooperate with the Shareholders at the cost and expense of Shareholders in filing any refund claim based on such payment provided that (i) the Shareholders shall incur all costs and expenses of filing and prosecuting such refund claim and (ii) the filing of such refund claim does not in the reasonable judgment of Buyer adversely affect Buyer or its Affiliates. The obligations of Shareholders pursuant to this Section 8.02(b) shall be joint and several.

8.03 Indemnification by Buyer. Subject to Section 8.06 and Section 8.07, Buyer covenants and agrees that it will indemnify, defend, protect and hold harmless Shareholders and their respective agents, representatives, Affiliates, beneficiaries and heirs and employees at all times from and after the date of this Agreement from and against all Losses incurred by any of such indemnified Persons as a result of or arising from (a) until the Expiration Date, any breach of the representations and warranties of Buyer set forth herein or in the Schedules attached hereto or certificates delivered in connection herewith or (b) any breach or nonfulfillment of any covenant or agreement on the part of Buyer under this Agreement.

8.04 Third Person Claims. (a) Promptly after any party entitled to indemnification under Sections 8.02 or 8.03 hereof (in such capacity, an “Indemnified Party”) has received notice of or has knowledge of any claim by a Person not a party to this Agreement (a “Third Person”), or of the commencement of any action or proceeding by a Third Person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement (a “Third Person Claim”), the Indemnified Party shall give to the party obligated to provide indemnification pursuant to Sections 8.02 or 8.03 hereof (in such capacity, the “Indemnifying Party”) prompt written notice of such claim or the commencement of such action or proceeding (a “Claim Notice”). Such Claim Notice shall state the nature and the basis of such Third Person

Claim and (to the extent feasible) a reasonable estimate of the amount being claimed (which estimate will not be conclusive of the final amount of such Third Person Claim). Except as Section 8.01 sets forth, the failure to promptly deliver a Claim Notice will not relieve the Indemnifying Party of its obligations to the Indemnified Party with respect to the related Third Person Claim except to the extent that the resulting delay is prejudicial to the defense of that Third Person Claim. Notwithstanding the foregoing and the following provisions of Section 8.04(b), Buyer shall be deemed to have delivered a sufficiently detailed Claim Notice with respect to each of the items set forth in Schedule 8.02 and with respect to each of the Existing Environmental Conditions referenced in clause (v) of Section 8.02(a) as to which Remediation Activities have been initiated prior to the Closing Date, and, to the extent any such items may involve any defense of any Third Person Claims, Shareholders shall be deemed to have elected to assume the defense of such Third Person Claims in accordance with the provisions of Section 8.04(b).

(b) Within 30 days after receipt of any Claim Notice (the “Election Period”), the Indemnifying Party must notify the Indemnified Party (i) whether the Indemnifying Party disputes its potential liability to the Indemnified Party under this Article VIII with respect to the related Third Person Claim and (ii) if the Indemnifying Party does not dispute its potential liability to the Indemnified Party with respect to that Third Person Claim, whether the Indemnifying Party desires, at the sole cost and expense of the Indemnifying Party, to defend the Indemnified Party against that Third Person Claim. If the Indemnifying Party does not dispute its potential liability to the Indemnified Party and notifies the Indemnified Party within the Election Period that the Indemnifying Party elects to assume the defense of a Third Person Claim specified in a Claim Notice, then the Indemnifying Party will have the right to defend, at its sole cost and expense, that Third Person Claim by all appropriate proceedings, which proceedings the Indemnifying Party must prosecute diligently to a final conclusion or settle at its discretion in accordance with this Section 8.04, and the Indemnified Party will furnish the Indemnifying Party with all information in its possession with respect to such claim and otherwise cooperate with the Indemnifying Party in the defense of that Third Person Claim. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any Third Person Claim, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement thereof; provided, however, that the Indemnified Party shall be entitled, at its expense, to participate in the defense of that Third Person Claim and the negotiation of any settlement thereof. The Indemnifying Party shall not settle any such Third Person Claim without the consent of the Indemnified Party (which consent may be withheld in the sole discretion of that Indemnified Party), unless the settlement thereof does not cause any adverse Tax consequences to the Indemnified Party or its affiliates for which the Indemnifying Party does not indemnify the Indemnified Party, imposes no liability or obligation on the Indemnified Party, and includes a complete release from liability benefiting the Indemnified Party. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Person Claim the Indemnifying Party controls under this Section 8.04 and will bear its own costs and expenses with respect to that participation; provided, however, that if the named parties to any such action (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party, and the Indemnified Party has been advised by counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the Indemnifying Party, then the Indemnified Party may employ

separate counsel at the expense of the Indemnifying Party, and, on its written notification of that employment, the Indemnifying Party will not have the right to assume or continue the defense of that action on behalf of the Indemnified Party; provided, further, that the Indemnified Party is hereby authorized, at the sole cost and expense of the Indemnifying Party, to file, during the Election Period, any motion, answer or other pleadings that the Indemnified Party deems necessary or appropriate to protect its interests or those of the Indemnifying Party.

(c) If with respect to a claim for indemnification under this Article VIII involving a Third Person Claim, the Indemnifying Party (i) within the applicable Election Period (A) disputes its potential liability to the Indemnified Party under this Article VII, (B) elects not to defend the Indemnified Party under Section 8.04(b) or (C) fails to notify the Indemnified Party that the Indemnifying Party elects to defend the Indemnified Party under Section 8.04(b) or (ii) elects to defend the Indemnified Party under Section 8.04(b), but fails diligently and promptly to prosecute or settle the Third Person Claim, then the Indemnified Party will have the right to defend, at the sole cost and expense of the Indemnifying Party (if the Indemnified Party is entitled to indemnification hereunder), the Third Person Claim by all appropriate proceedings, which proceedings the Indemnified Party must promptly and vigorously prosecute to a final conclusion or settle. The Indemnified Party will have full control of such defense and proceedings. Notwithstanding the foregoing, if the Indemnifying Party has delivered a written notice to the Indemnified Party to the effect that the Indemnifying Party disputes its potential liability to the Indemnified Party under this Article VIII and if that dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party will not be required to bear the costs and expenses of the Indemnified Party’s defense under this Section 8.04 or of the Indemnifying Party’s participation therein at the Indemnified Party’s request. The Indemnifying Party may participate in, but not control, any defense or settlement the Indemnified Party controls under this Section 8.04(c), and the Indemnifying Party will bear its own costs and expenses with respect to that participation.

(d) Payments of all amounts owing by an Indemnifying Party under this Article VIII relating to a Third Person Claim will be made within 10 days after the latest of (i) the settlement of that claim, (ii) the expiration of the period for appeal of a final adjudication of that claim or (iii) the expiration of the period for appeal of a final adjudication of the Indemnifying Party’s liability to the Indemnified Party under this Agreement in respect of that claim.

8.05 Non-Third Person Claims. In the event that any Indemnified Party asserts the existence of a claim giving rise to Losses (but excluding Third Person Claims), such party shall give written notice to the Indemnifying Party. Such written notice shall state that it is being given pursuant to this Section 8.05, specify the nature and amount of the claim asserted, and indicate the date on which such assertion shall be deemed accepted and the amount of the claim deemed a valid claim (such date to be established in accordance with the next sentence). If such Indemnifying Party, within 30 days after the mailing of notice by such Indemnified Party, shall not give written notice to such Indemnified Party announcing such Indemnifying Party’s intent to contest such assertion of such Indemnified Party, such assertion shall be deemed accepted and the amount of such claim shall be deemed a valid claim. In the event, however, that such Indemnifying Party contests such assertion of a claim by giving such written notice to the Indemnified Party within said period, then the parties shall act in good faith to reach agreement regarding such claim. If the parties cannot resolve such dispute after good faith negotiations

with respect thereto within 60 days after the notice provided by the Indemnifying Party, such dispute shall be submitted to arbitration in accordance with the provisions of Section 12.10. In the event that arbitration shall arise with respect to any such claim, the prevailing party shall be entitled to reimbursement of costs and expenses incurred in connection with such arbitration including reasonable attorneys’ fees.

8.06 Indemnification Threshold. Neither Shareholders, on the one hand, nor Buyer, on the other hand, have any indemnification obligation to the other under the provisions of Section 8.02 (other than clauses (iii), (iv) and (v) of Section 8.02(a), Section 8.02(b) and the indemnification obligations with respect to any breach of the representations and warranties set forth in Section 5.07, as they pertain to parcels of Land in which the Acquired Entities hold fee title, or the covenants set forth in Section 7.10, as to which the condition set forth in this sentence shall not apply) or Section 8.03, as the case may be, until such time as the aggregate amount of such obligations exceed $1,000,000, at which time the indemnification obligations shall be effective as to all amounts, including the initial $1,000,000. Notwithstanding the foregoing, the foregoing provisions of this Section 8.06 shall not apply to any fraudulent misrepresentation.

8.07 Indemnification Limitation. Subject to the last sentence of Section 8.06, (i) the aggregate joint and several indemnification obligations of Shareholders under Section 8.02 and (ii) the aggregate indemnification obligations of Buyer under Section 8.03 shall, in each case, be limited to an amount equal to the Consideration (as determined after giving effect to the Consideration Adjustment pursuant to Section 7.12). Notwithstanding the foregoing, the limitations set forth in this Section 8.07 shall not apply to fraudulent misrepresentations. Any amount that becomes payable pursuant to this Article VIII in respect of indemnification for any damages, loss, cost or expense shall be reduced by the amount of any insurance proceeds, including title insurance, actually received by the party suffering the damages, loss, cost or expense with respect thereto (net of any resulting increase in insurance premiums); provided, however, that nothing herein shall obligate Buyer or any Acquired Entity to maintain such insurance policies after the Closing or to insure any particular risk after the Closing, and nothing herein shall require Buyer or any Acquired Entity to make application to any insurance of Buyer or of any Acquired Entity that is obtained or maintained on its behalf after the Closing. The parties to this Agreement agree to treat all payments made in respect of indemnification for any damages, loss, cost or expense pursuant to this Article VIII as adjustments to the Consideration for Tax purposes, except to the extent otherwise required by applicable Law, in which event any amount that is payable pursuant hereto shall be increased by the amount that causes the aggregate payment, when reduced by all Taxes payable in respect of the receipt of the payment, to be equal to such damages, loss, cost or expense.

8.08 Indemnification for Negligence of Indemnified Party. THE RIGHTS TO INDEMNIFICATION UNDER THIS ARTICLE VIII INCLUDE RIGHTS TO INDEMNIFICATION FOR THE RESULTS OF AN INDEMNIFIED PARTY’S ACTUAL OR ALLEGED SOLE OR CONTRIBUTORY NEGLIGENCE OR STRICT LIABILITY, IF SUCH INDEMNIFIED PARTY WOULD OTHERWISE BE ENTITLED TO INDEMNIFICATION HEREUNDER.

ARTICLE IX
NONCOMPETITION COVENANTS

9.01 Prohibited Activities.

(a) Except as set forth on Schedule 9.01, each Shareholder (which term, for purposes of this Article IX and Article X only, shall include each individual shareholder or Affiliate of Atlas who has joined in the execution of this Agreement, as reflected on the signature pages hereto) will not, for five years following the Closing Date (such period being herein referred to as the “Noncompete Term”), directly or indirectly, for itself or himself or on behalf of or in conjunction with any other Person or:

(i) engage, as an officer, director, shareholder, owner, investor, lender, partner, joint venturer, or in a managerial or advisory capacity, whether as an employee, independent contractor, consultant or advisor, or as a sales representative, dealer or distributor, in any Competitive Business in the State of Texas or within a radius of 100 air miles of any plant or other operating facility in which any Acquired Entity or Buyer was engaged in business on the date immediately prior to the Closing Date (collectively, the “Territory”);

(ii) call upon or otherwise solicit any person, who is, at that time, an employee or consultant of Buyer or any of its Affiliates, for the purpose or with the intent or effect of enticing such employee or consultant away from or out of the employ or contract with Buyer or any of its Affiliates;

(iii) call upon or otherwise solicit any Person which is, at that time, or which has been, within two years prior to that time, a customer of the Acquired Business, Buyer or any of the Affiliates of such parties within the Territory for the purpose of soliciting or selling services or products in a Competitive Business within the Territory; or

(iv) call upon or otherwise solicit any Entity which the Acquired Business or Buyer has called on in connection with the possible acquisition by either of them of such Entity or of which either of them has made an acquisition analysis, with the knowledge of that Entity’s status as an acquisition candidate of Buyer, for the purpose of acquiring that Entity or arranging the acquisition of that Entity by any Person other than Buyer

(b) Notwithstanding the above, Section 9.01(a) shall not be deemed to prohibit any Shareholder from acquiring, as a passive investor with no involvement in the operations of the business, not more than five percent of the capital stock of a Competitive Business whose stock is publicly traded on a national securities exchange or the NASDAQ National Market.

9.02 Equitable Relief. Because of the difficulty of measuring economic losses to Buyer as a result of a breach of the foregoing covenant, because a breach of such covenant would diminish the value of the assets, properties and business of the Acquired Business being sold pursuant to this Agreement, and because of the immediate and irreparable damage that would be caused to Buyer for which Buyer would have no other adequate remedy, since monetary damages alone may not be an adequate remedy, each Shareholder agrees that the foregoing

covenant may be enforced against such individual or Entity by, without limitation, injunctions, restraining orders and other equitable actions.

9.03 Reasonable Restraint. It is agreed by the parties hereto that the foregoing covenants in this Article IX are necessary in terms of time, activity and territory to protect Buyer’s interest in the assets, properties and business being acquired pursuant to the terms of this Agreement and impose a reasonable restraint on Shareholders in light of the activities and businesses of Buyer on the date of the execution of this Agreement and the current plans of Buyer.

9.04 Severability; Reformation. The covenants in this Article IX are severable and separate, and the unenforceability of any specific covenant shall not affect the continuing validity and enforceability of any other covenant. In the event any court of competent jurisdiction shall determine that the scope, time or territorial restrictions set forth in this Article IX are unreasonable and therefore unenforceable, then it is the intention of the parties that such restrictions be enforced to the fullest extent which the court deems reasonable and this Agreement shall thereby be reformed.

9.05 Material and Independent Covenant. Shareholders acknowledge that their agreements and the covenants set forth in this Article IX are material conditions to Buyer’s agreements to execute and deliver this Agreement and to consummate the transactions contemplated hereby and that Buyer would not have entered into this Agreement without such covenants. All of the covenants in this Article IX shall be construed as an agreement independent of any other provision in this Agreement. The existence of any claim or cause of action by any Shareholder against Buyer, whether predicated on this Agreement or otherwise, will not constitute a defense to the enforcement by Buyer of any of the covenants of this Article IX. It is specifically agreed that the time period Section 9.01 specifies will be computed in the case of each Shareholder by excluding from that computation any time during which that Shareholder is in violation of any provision of Section 9.01. The covenants this Article IX contains will not be affected by any breach of any other provision hereof by any party hereto.

ARTICLE X
NONDISCLOSURE OF CONFIDENTIAL INFORMATION

10.01 General. Each Shareholder recognizes and acknowledges that he had in the past, currently has, and in the future will have, access to certain confidential information relating to the Acquired Entities, the Acquired Business and/or Buyer, including lists of customers, operational policies, and pricing and cost policies that are, and following the Closing will be, valuable, special and unique assets of Buyer and the Acquired Entities. Each Shareholder agrees that he or she will not use or disclose such confidential information to any Person, for any purpose whatsoever, except as is required in the course of performing his or her duties, if any, to Buyer, unless (a) such information becomes known to the public generally through no fault of any Shareholder, or (b) disclosure is required by Law, provided that prior to disclosing any information pursuant to this clause (b) the disclosing party shall give prior written notice thereof to Buyer and provide Buyer with the opportunity to contest such disclosure.

10.02 Equitable Relief. Because of the difficulty of measuring economic losses to Buyer as a result of the breach of the foregoing covenant, because a breach of such covenant would diminish the value of the assets, properties and business of the Acquired Business being sold pursuant to this Agreement, and because of the immediate and irreparable damage that would be caused to Buyer for which it would have no other adequate remedy, since monetary damages alone may not be an adequate remedy, each Shareholder agrees that the foregoing covenants may be enforced against such individual or Entity by, without limitation, injunctions, restraining orders and other equitable actions. Nothing herein shall be construed as prohibiting Buyer from pursuing any other available remedy for such breach or threatened breach, including, without limitation, the recovery of damages.

ARTICLE XI
TERMINATION

11.01 Termination of This Agreement. This Agreement may be terminated at any time prior to the Closing solely:

(a) by the mutual written consent of Buyer and Shareholders;

(b) by Buyer, on the one hand, or by Shareholders, acting together, on the other hand, if the transactions this Agreement contemplates will take place at the Closing shall not have been consummated by August 31, 2006, unless the failure of those transactions to be consummated results from the willful failure of the party (or in the case of Shareholders, any of them or any of the Acquired Entities) seeking to terminate this Agreement to perform or adhere to any covenant or agreement required hereby to be performed or adhered to by it or them prior to or at the Closing;

(c) by Buyer if (i) either Shareholder or any Acquired Entity shall have failed to perform in any material respect any of its respective covenants and agreements contained in this Agreement which failure would give rise to the failure of the condition set forth in Section 4.04(b) or (ii) the respective representations and warranties of Shareholders and the Companies contained in this Agreement are or shall become untrue (without giving effect to any materiality qualification or standard contained in any such representations and warranties) in any respect, which untruth would give rise to the failure of the condition set forth in Section 4.04(a), except, in either case, where the failure to perform or to be true and correct, individually or in the aggregate, would not have a Material Adverse Effect; or

(d) by Shareholders if (i) Buyer shall have failed to perform in any material respect any of its respective covenants and agreements contained in this Agreement which failure would give rise to the failure of the condition set forth in Section 4.03(b), or (ii) the representations and warranties of Buyer contained in this Agreement are or shall become untrue(without giving effect to any materiality qualification or standard contained in any such representations and warranties) in any respect, which untruth would give rise to the failure of the condition set forth in Section 4.03(a), except where the failure to perform or to be true and correct, individually or in the aggregate, would not have a material adverse effect on the ability of Buyer to perform its obligations hereunder.

11.02 Liabilities in Event of Termination. If this Agreement is terminated under Section 11.01, there shall be no liability or obligation on the part of any party hereto except (i) as Section 7.07 provides and (ii) to the extent that such liability is based on the breach by that party of any of its covenants this Agreement sets forth. Nothing in this Article XI will release Buyer, Shareholders or the Companies from liability for any breach of this Agreement prior to its termination.

ARTICLE XII
MISCELLANEOUS

12.01 Successors and Assigns; Rights of Parties. This Agreement and the rights of the parties hereunder may not be assigned (except by operation of Law) without the prior written consent of the other parties hereto; provided, however, that Buyer may, without the prior written consent of any Acquired Entity or either Shareholder, assign its rights and obligations under this Agreement to (i) any of its Affiliates or (ii) any of Buyer’s lenders or holders of debt instruments of Buyer for collateral security purposes only. Subject to the previous sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto, the successors of Buyer and the Companies, and the respective successors, heirs and legal representatives of Shareholders. Except as expressly provided in Article VIII or in this Section 12.01, nothing in this Agreement is intended or will be construed, deemed or interpreted to confer upon or give any Person other than the parties hereto any rights or remedies under or by reason of this Agreement or any transaction contemplated hereby.

12.02 Entire Agreement; Amendment; Waivers. This Agreement (including the Exhibits and Schedules hereto) and the documents delivered pursuant hereto constitute the entire agreement and understanding among Shareholders, the Companies and Buyer and supersede any prior agreement and understanding relating to the subject matter of this Agreement, including the Letter of Intent. This Agreement may be modified or amended only by a written instrument executed by Shareholders, the Companies and Buyer, acting through their respective officers, duly authorized by their respective Boards of Directors. Any right hereunder may be waived only by a written instrument executed by the party waiving such right. The waiver of any of the terms and conditions hereof shall not be construed or interpreted as, or deemed to be, a waiver of any other term or condition hereof.

12.03 Counterparts; Facsimile Signatures. This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute but one and the same instrument. Facsimile transmission of any signed original document and/or retransmission of any signed facsimile transmission will be deemed the same as delivery of an original. At the request of any party, the parties will confirm facsimile transmission by signing a duplicate original document.

12.04 Brokers and Agents. Each party hereto represents and warrants that it employed no broker or agent in connection with the transactions contemplated by this Agreement. Each party agrees, without regard to any threshold or limitation Article VIII sets forth, to indemnify each other party hereto against all loss, cost, damages or expense arising out of claims for fees or commissions of brokers employed or alleged to have been employed by such indemnifying party in connection with the transactions contemplated by this Agreement.

12.05 Notices. All notices and communications required or permitted hereunder shall be in writing and may be given by overnight delivery or by depositing the same in the United States mail, addressed to the party to be notified, postage prepaid and registered or certified with return receipt requested, or by delivering the same in person to an officer or agent of such party as follows:

12.06 Exercise of Rights and Remedies. Except as otherwise provided herein, no delay of or omission in the exercise of any right, power or remedy accruing to any party as a result of any breach or default by any other party under this Agreement shall impair any such right, power or remedy, nor shall it be construed as a waiver of or acquiescence in any such breach or default, or of any similar breach or default occurring later; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default occurring before or after that waiver. No right, remedy or election provided by any term of this Agreement will be

deemed exclusive, but each will be cumulative with all other rights, remedies and elections available at law or in equity.

12.07 Reformation and Severability. In case any provision of this Agreement shall be invalid, illegal or unenforceable, it shall, to the extent possible, be modified in such manner as to be valid, legal and enforceable, but so as to most nearly retain the intent of the parties, and if such modification is not possible, such provision shall be severed from this Agreement, and in either case, the validity, legality and enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby.

12.08 Captions. The Article and Section headings contained in this Agreement are inserted for convenience of reference only and shall not affect the meaning or interpretation of this Agreement.

12.09 Governing Law. This Agreement shall be construed in accordance with the laws of the State of Texas (without regard to any conflicts of laws provisions thereof that would result in the application of the laws of any other jurisdiction).

12.10 Dispute Resolution.

(a) Except with respect to injunctive relief as provided in Section 7.13, Section 9.02 and Section 10.02 (which relief may be sought from any court or administrative agency with jurisdiction with respect thereto), any unresolved dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration in accordance with the rules of the American Arbitration Association then in effect. The arbitration shall be conducted by a retired judge with commercial litigation experience employed by the Dallas, Texas office of J.A.M.S./Endispute, Inc. (“JAMS”). The arbitration shall be held in JAMS’ Dallas, Texas office.

(b) The parties shall obtain from JAMS a list of the retired judges available to conduct the arbitration. The parties shall use their reasonable efforts to agree upon a judge to conduct the arbitration. If the parties cannot agree upon a judge to conduct the arbitration within 10 days after receipt of the list of available judges, the parties shall ask JAMS to provide the parties a list of three available judges (the “Judge List”). Within five days after receipt of the Judge List, each party shall strike one of the names of the available judges from the Judge List and return a copy of such list to JAMS and the other party. If two different judges are stricken from the Judge List, the remaining judge shall conduct the arbitration. If only one judge is stricken from the Judge List, JAMS shall select a judge from the remaining two judges on the Judge List to conduct the arbitration.

(c) The arbitrator shall not have the authority to add to, detract from, or modify any provision hereof nor to award punitive damages to any injured party. The arbitrator shall have the authority to order payment of damages, reimbursement of costs, including those incurred to enforce this Agreement, and interest thereon in the event the arbitrator determines that a material breach of this Agreement has occurred. A decision by the arbitrator shall be final and binding. Judgment may be entered on the arbitrator’s award in any court having jurisdiction. The arbitrator shall issue a reasonably detailed statement of his findings of fact and conclusions of law. The parties shall be entitled to discovery.

July [ ], 2006

U.S. Concrete, Inc.
▇▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇
▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

We have acted as special counsel to Alliance Haulers, Inc., a Texas corporation (“Alliance”), Alberta Investments Inc., a Texas corporation (“Alberta”), Atlas Concrete Inc., an Alberta, Canada corporation (“Atlas”), and Wild Rose Holdings Ltd., a Jersey corporation (“Wild Rose”), in connection with the Stock Purchase Agreement, dated as of [ ], 2006, to which U.S. Concrete, Inc., a Delaware corporation (“Buyer”), Alliance, Alberta, Atlas and Wild Rose are parties (the “Stock Purchase Agreement”). We deliver this opinion letter to you pursuant to Section 4.04(e)(2) of the Stock Purchase Agreement in connection with the closing of the sale to Buyer in accordance with the Stock Purchase Agreement of the certificates representing the Companies Capital Stock. Capitalized terms this opinion letter uses, but does not define, have the respective meanings the Stock Purchase Agreement specifies.

We have examined the executed originals, or copies certified or otherwise identified to our satisfaction, of the Stock Purchase Agreement, the Promissory Note dated [ ], 2006 relating to the Loan from Buyer to Atlas Investments, Inc., a Nevada corporation (“AII”), pursuant to Section 7.14 of the Stock Purchase Agreement (the “Promissory Note”), the Pledge and Security Agreement, dated as of [ ], 2006, by and among Atlas, Wild Rose and Alberta in favor of Buyer (the “Pledge Agreement”) relating to the Loan and the related guaranties provided by Atlas, Wild ▇▇▇▇, ▇▇▇▇▇▇▇ and Alliance pursuant to the Promissory Note (the “Guaranties”), the organizational documents of each of the Companies, the Shareholders and AII, each as amended to date, minute books and certain other records of each of the Companies, the Shareholders and AII, certificates of public officials and of representatives of each of the Companies, the Shareholders and AII, and such statutes and other instruments and documents as we have deemed necessary as a basis for the opinions hereinafter expressed. The Stock Purchase Agreement, the Promissory Note (including the Guaranties set forth therein) and the Pledge Agreement are hereinafter referred to as the “Transaction Documents.”

In rendering the following opinions, we have relied as to matters of fact on certificates of the officers of the Companies and the Shareholders. We have assumed, without independent investigation, the legal capacity of natural persons, the authenticity of all documents and records submitted to us as originals, the conformity to original documents and records of all documents and records submitted to us as copies or by facsimile or electronic transmission and the authenticity of the original of such copies, and the accuracy and authenticity of certificates of public officials. Our opinions expressed in opinion paragraph 1 as to the existence and good

standing of each entity described therein are based solely on our review of certificates of public officials of the applicable jurisdictions.

We have further assumed, to the extent relevant to our opinions expressed below, that (i) the Transaction Documents constitute the legal, valid and binding obligations of each party thereto (except that we have not made this assumption with respect to the Companies, the Shareholders or AII) and (ii) all terms, provisions and conditions relating to the transactions referred to in this opinion letter are completely and correctly reflected in the Stock Purchase Agreement.

On the basis of the foregoing, and subject to the assumptions, limitations, qualifications and exceptions herein set forth, we are of the opinion that:

	1.		Each Company, each Shareholder and AII is a corporation duly incorporated, validly existing and in good standing under the laws of its jurisdiction of incorporation and has all requisite corporate power and authority to own, lease and operate its assets and properties and to carry on its business as such business is currently being conducted.

	2.		Each of the Companies, the Shareholders and AII has all requisite corporate power and authority to execute, deliver and perform its respective obligations under the Transaction Documents and to effectuate the transactions the Transaction Documents contemplate, including, without limitation: (i) the borrowing by AII pursuant to the Loan and AII’s execution and delivery to Buyer of the Promissory Note; (ii) the Guaranties by each of Atlas, Wild ▇▇▇▇, ▇▇▇▇▇▇▇ and Alliance and the execution and delivery to Buyer of the Promissory Note by each of Atlas, Wild ▇▇▇▇, ▇▇▇▇▇▇▇ and Alliance to evidence the Guaranties; (iii) AII’s use of the proceeds of the Loan to effect a distribution to Alberta; and (iv) Alberta’s use of those proceeds to effect a distribution to Atlas with respect to the outstanding shares of preferred stock of Alberta. The execution and delivery by each Company, each Shareholder and AII of the Transaction Documents to which it is a party and the performance by that entity of its respective obligations thereunder have been duly authorized by all necessary corporate action and proceedings required under that entity’s charter documents and all applicable Laws.

	3.		Each of the Transaction Documents to which either Company is a party has been duly and validly executed and delivered by that Company and constitutes its valid and binding agreement, enforceable against that party in accordance with its terms. Each of the Transaction Documents to which either Shareholder is a party has been duly and validly executed and delivered by that Shareholder and constitutes its valid and binding agreement, enforceable against that party in accordance with its terms. Each of the Transaction Documents to which AII is a party has been duly and validly executed and delivered by AII and constitutes its valid and binding agreement, enforceable against that party in accordance with its terms.

	4.		The execution, delivery and performance by each of the Companies, the Shareholders and AII of the Transaction Documents to which it is a party and the consummation by that party of the transactions contemplated thereby (including, without limitation, the transactions referred to in clauses (i) through (iv) of the first sentence of paragraph 2, above) will not violate or result in a breach of any provision of, or constitute a default (or an event that, with notice or lapse of time or both, would constitute a default) or result in the termination of, or accelerate the performance required by, or result in a right of termination or acceleration under, or result in the creation of any Encumbrance upon any of the properties or assets of any Acquired Entity or the Acquired Business under any of the terms, conditions or provisions of (i) the organizational documents of any Acquired Entity, (ii) any Law applicable to any Shareholder, any Acquired Entity, the Acquired Business or any of the properties or assets of any Shareholders, any Acquired entity or the Acquired Business or (iii) any agreement, note, bond, mortgage, indenture, deed of trust, license, franchise, Permit, concession, lease or other instrument, obligation or agreement of any kind to which either Shareholder, any Acquired Entity or the Acquired Business is now a party or by which the Acquired Business, any Acquired Entity or any of their respective properties or assets may be bound or affected (including, without limitation, the Listed Agreements), other than, in the case of clause (iii), the Encumbrances expressly created by the terms of the Promissory Note and the Pledge Agreement.

	5.		Except as disclosed pursuant to the Stock Purchase Agreement, no Governmental Approvals are required to be obtained, and no reports or notices or filings with any Governmental Authority are required to be made by, either Company, either Shareholder or AII under any Applicable Governmental Requirement for the execution, delivery or performance by them of the Transaction Documents or the effectuation of the transactions described therein.

	6.		To our knowledge, there are no outstanding subscriptions, options, warrants, calls, convertible or exchangeable securities, other conversion rights or commitments of any kind that obligate any Acquired Entity to issue any of its capital stock or Shareholders to transfer any of the equity interests in any Acquired Entity. To our knowledge, except as disclosed pursuant to the Stock Purchase Agreement, none of the Companies or the Shareholders is a party to or bound by any agreement, instrument, contract, commitment or understanding of any character, except for the Stock Purchase Agreement, providing for the sale, assignment, conveyance, encumbrance, transfer or delivery of any Capital Stock of any Acquired Entity or all or substantially all the assets of any Acquired Entity.

	7.		To our knowledge, there are no claims, actions, suits or proceedings, pending or threatened against or affecting any Acquired Entity that (a) questions the validity of the Stock Purchase Agreement or any action taken or to be taken by either Company or either Shareholder in connection with the Stock Purchase Agreement, at law or in equity, before or by any Governmental Authority or before any arbitrator, or (b) if adversely determined, would have a material

			adverse effect on the ability of either Company or either Shareholder to perform its respective obligations under the Stock Purchase Agreement.

	8.		On the date hereof: (a) the authorized capital stock of Alliance consists solely of 1,000,000 shares of common stock, of which 1,000 shares are issued and outstanding and owned beneficially and of record by Wild Rose, and the authorized capital stock of Alberta consists solely of 1,000 shares of Series B common stock, of which 330 shares are issued and outstanding and owned beneficially and of record by Wild Rose, and 500 shares of Series A preferred stock, of which 15 shares are issued and outstanding and owned beneficially and of record by Atlas; (b) the authorized, issued and outstanding capitalization of each of the other Acquired Entities is as set forth on Schedule 5.03 to the Stock Purchase Agreement; and (c) all of the issued and outstanding shares of Capital Stock of each of the Acquired Entities (i) have been duly authorized and validly issued, (ii) are fully paid and nonassessable, except, as to any Acquired Entity that is a Texas limited partnership, as to the general partner interests therein and as such nonassessability may be affected by Sections 3.03, 5.02 and 6.07 of the Texas Revised Limited Partnership Act, and (iii) to our knowledge, have not been issued in violation of any preemptive or other similar rights.

The validity and enforceability of the Transaction Documents may be limited by bankruptcy, insolvency, reorganization, rearrangement, moratorium, liquidation, and other similar laws now or hereafter in effect and affecting creditors’ rights generally, and by general principles of equity (including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance, injunctive relief or other equitable remedies), regardless of whether such validity, binding effect and enforceability are considered in a proceeding in equity or at law.

For purposes of this opinion letter, we have reviewed only those laws, rules and regulations that in our experience are normally applicable to transactions of the type described in the Transaction Documents and, to the extent relevant to any of our opinions, only those agreements, judgments and orders brought to our attention by the Company.

We neither express nor imply any opinion regarding: (i) the validity or enforceability of any provision of any Transaction Document that purports to: (a) release a party from liability for its own negligence, or in cases where the party released is strictly liable, or to the extent that any such release provisions are inconsistent with public policy; (b) exclude all conflicts-of-law rules; (c) prohibit the non-written waiver or modification of any provision of any Transaction Document; (d) confer, waive or consent to the jurisdiction of any court; (e) waive the objection of inconvenient forum; (f) provide for severability and reformation or (g) restrict the ability of any Person to engage in any business or trade activities in competition with another Person; or (ii) the validity or enforceability of provisions relating to delay or omission of enforcement of rights or remedies.

We have not made any examination of any accounting or financial matters, and we express no opinion with respect thereto.

With respect to any opinion expressed herein that is qualified by the phrase “to our knowledge” or is otherwise qualified by words of like import, we are referring to the conscious awareness of the lawyers currently practicing law with this Firm who have had involvement in representing the Company in connection with the transactions described in the Transaction Documents.

of the laws of any other jurisdiction.

PROMISSORY NOTE



$[33],000,000.00		July [___], ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇

FOR VALUE RECEIVED, Atlas Investments, Inc., a Nevada corporation (herein referred to as the “Maker”), hereby promises and agrees to pay to the order of U.S. Concrete, Inc., a Delaware corporation (the “Holder”), the principal amount of [____________] MILLION DOLLARS ($[33],000,000), together with interest on the unpaid principal sum from (and including) the date hereof until (but excluding) the date on which that unpaid principal sum shall become due and payable (whether on the Maturity Date (as hereinafter defined) or upon acceleration thereof pursuant to the provisions of Section 3(b)), at the rate of five percent (5.0%) per annum as hereinafter provided; provided, however that, notwithstanding the foregoing, if the Closing (as hereinafter defined) under the Stock Purchase Agreement (as hereinafter defined) does not occur as a result of the failure of a condition set forth in Section 4.03 of the Stock Purchase Agreement or the failure of the Holder to obtain the Financing (as defined in the Stock Purchase Agreement), no such interest shall accrue. Any past due principal and interest owing under this Promissory Note (this “Note”) shall bear interest from and after the date such obligations first become payable until paid at a per annum rate equal to the lesser of (i) eighteen percent (18.0%) or (ii) the maximum nonusurious rate allowed under applicable law (the “Highest Lawful Rate”), which interest shall be payable upon demand. All interest hereunder shall be calculated on the basis of a 365-day year for the actual number of days elapsed. References in this Note to the “Stock Purchase Agreement” mean that certain Stock Purchase Agreement made as of June 27, 2006 by and among the Holder, Atlas Concrete Inc., an Alberta, Canada corporation (“Atlas”), Wild Rose Holdings Ltd., a Jersey corporation (“Wild Rose”), Alberta Investments Inc., a Texas corporation of which the Maker is a direct, wholly owned subsidiary (“Alberta”), Alliance Haulers, Inc., a Texas corporation (“Alliance”), and the Maker.

Payment Obligations.

(a)

Subject to Section 3(b), the principal amount of this Note shall be due and payable in full immediately upon the first to occur of (i) the time of the Closing (as defined in the Stock Purchase Agreement) or (ii) 9:00 A.M., Central Time, on July [___], 2006 (the date of the first such time to occur is referred to herein as the “Maturity Date”). Interest on the unpaid principal amount of this Note shall accrue and shall be payable as provided above. Payments of principal and interest shall be made in lawful money of the United States of America, by wire transfer of immediately available funds to such bank account of the Holder as the Holder may designate from time to time by written notice to the Maker. Any check, draft or other instrument given in payment of all or any

			portion of this Note may be accepted by the Holder and handled in collection in a customary manner, but the same shall not constitute payment hereunder or diminish any rights of the Holder except to the extent that actual cash proceeds of such instruments are unconditionally received by the Holder. Any payment (excluding any prepayment) on or in respect of this Note shall be applied first to accrued but unpaid interest and then to the principal balance hereof. The unpaid principal may, at the option of the Maker, be prepaid, in whole or in part, at any time without premium or penalty, through the payment of an amount equal to 100% of the principal amount being prepaid, together with all accrued and unpaid interest on this Note to (but excluding) the date of the prepayment. At such time as this Note is paid or prepaid in full, it shall be surrendered to the Maker and cancelled and shall not be reissued.

	(b)		As further provided in Section 5, each of Atlas, Wild ▇▇▇▇, ▇▇▇▇▇▇▇ and Alliance (each, a “Guarantor”) is guaranteeing the payment obligations of the Maker under this Note. Pursuant to the provisions of the Pledge and Security Agreement dated as of the date of this Note to which Atlas, Wild ▇▇▇▇, ▇▇▇▇▇▇▇ and the Holder are parties (the “Pledge Agreement”), the guarantee obligations of the Guarantors are being secured by a security interest in all of the outstanding capital stock of each of Alberta, Alliance and the subsidiaries of Alberta specified in the Pledge Agreement (the “Collateral”). Each of the Maker and the Guarantors sometimes is referred to herein as an “Obligor.”

	(c)		Regardless of any provision contained herein, or in any other document executed in connection with this Note, the Holder shall never be entitled to contract for, charge, take, reserve, receive, collect, or apply, as interest on any obligation payable under this Note, any unearned interest or any amount in excess of the Highest Lawful Rate, and in the event the holder hereof ever contracts, for charges, takes, reserves, receives, collects or applies, as interest, any unearned interest or any such excess, such amount shall be deemed a partial prepayment of principal, and, if the principal hereof is paid in full, any remaining excess shall forthwith be refunded to the Maker.

Certain Covenants. The Obligors hereby covenant and agree as follows, after the date of the Note and until such time as this Note has been paid in full in cash:

	(f)		Notification of default. Each Obligor shall notify the Holder, immediately after receipt by such Obligor, of any notice of default received by it under any Interest-Bearing Debt (as defined in the Stock Purchase Agreement) or any agreement or instrument governing or creating any Interest-Bearing Debt or any material Indebtedness (as hereinafter defined) of such Obligor or any of its consolidated subsidiaries.

	(m)		Prohibition on loans. No Obligor shall make loans to any person or entity.

Events of Default and Remedies.

(a)

Events of Default. So long as this Note has not been paid in full in cash, each of the following events will constitute an “Event of Default”:

	(i)		any default in the payment of the principal or accrued interest payable under this Note, as and when the same shall become due and payable;

	(ii)		any breach of any of the covenants contained in Section 2;

	(iii)		commencement of an involuntary case or other proceeding against any Obligor seeking (A) liquidation, reorganization, or other relief with respect to it or its debts under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect or (B) the appointment of a receiver, liquidator, custodian, or trustee of any Obligor or for all or substantially all the property and other assets of any Obligor; or

	(iv)		(A) commencement of a voluntary case by any Obligor under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, (B) consent by any Obligor to the entry of an order for relief in an involuntary case against such Obligor under any such law, (C) consent by any Obligor to the appointment or taking possession by a receiver, liquidator, custodian, or trustee of such Obligor or for all or substantially all its assets or (D) a general assignment by any Obligor for the benefit of its creditors.

	(b)		Remedies. If an Event of Default shall occur, then, without any notice to the Maker or any other act by the Holder, the entire principal amount of this Note (together with all accrued interest thereon) shall become immediately due and payable without presentment, demand, protest, or other notice of any kind, all of which are hereby expressly waived by the Maker.

	(c)		Expenses. If an Event of Default shall occur, the Maker shall pay, and save the Holder harmless against liability for the payment of, all reasonable expenses, including reasonable attorneys’ fees, incurred by the Holder in enforcing its rights hereunder.

Waivers; Amendments. To the extent permitted by applicable law, each Obligor, for itself and its legal representatives, successors and assigns, hereby expressly waives demand for payment, presentment, notice of dishonor, notice of intent to demand, notice of acceleration, notice of intent to accelerate, protest, notice of protest and diligence in collecting and the bringing of suit against the Maker or any other Obligor with respect to this Note. The Obligors agree that the Holder may extend the time for repayment or accept partial payment an unlimited number of times without discharging or releasing any of the Obligors from their respective obligations under this Note (including the Guaranties). No delay or omission on the part of the Holder in exercising any power or right in connection herewith shall operate as a waiver of such right or any other right under this Note (including the Guaranties), nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. No amendment, modification, or waiver of any provision of this Note (including the Guaranties), nor any consent to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the person against whom enforcement thereof is to be

			sought, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. Each Obligor also hereby expressly waives, as a defense, any counterclaim, setoff or claim which such Obligor may now or hereafter have against the Holder.

	5.		Guaranties. (a) Subject to the terms and conditions of this Note, the Guarantors hereby, jointly and severally, unconditionally guarantee to the Holder the prompt and complete payment in cash when due of all the Maker’s payment obligations to the Holder under this Note (the “Obligations”). An Event of Default under this Note shall constitute an event of default under the guaranties of the Guarantors provided in this Section 5 (the “Guaranties”), and shall entitle the Holder to accelerate the obligations of the Guarantors hereunder in the same manner and to the same extent as the Obligations. The Guaranties constitute guarantees of payment when due and not of collection.

	(b)		Anything herein to the contrary notwithstanding, the maximum liability of each Guarantor hereunder shall in no event exceed the amount which can be guaranteed by such Guarantor under applicable federal and state laws relating to fraudulent transfers or conveyances or to the insolvency of debtors (after giving effect to any right of contribution from the other Guarantor).

	(c)		The Guarantors shall not exercise any rights which they may acquire by way of subrogation to the rights of the Holder hereunder until all the Obligations shall have been paid in full in cash. Subject to the foregoing, upon payment of all the Obligations, the Guarantors shall be subrogated to the rights of the Holder against the Maker, and the Holder agrees to take such steps as the Guarantors may reasonably request to implement such subrogation.

	(d)		To the maximum extent permitted by applicable law, the Guarantors understand and agree that the Guaranties shall be construed as continuing, complete, absolute, and unconditional guarantees of payment without regard to, and each Guarantor hereby waives any defense of a surety or guarantor or any other obligor on any obligations arising in connection with or in respect of, and hereby agrees that its obligations hereunder shall not be discharged or otherwise affected as a result of, any of the following: (i) any defense, setoff, or counterclaim (other than the defense of payment or performance in full) which may at any time be available to or be asserted by the Maker against the Holder; (ii) the insolvency, bankruptcy arrangement, reorganization, adjustment, composition, liquidation, disability, dissolution, or lack of power of the Maker or any of the other Guarantors, or any sale, lease, or transfer of any or all of the assets of the Maker or any of the other Guarantors, or any change in the shareholders or other equity owners of the Maker or any of the other Guarantors; (iii) any change in the corporate or other existence, structure, or ownership of any other Obligor; (iv) the absence of any attempt to collect the Obligations or

any part of them from any other Obligor; or (v) any other circumstance or act which constitutes, or might be construed to constitute, an equitable or legal discharge of the Maker for the Obligations, or of such Guarantor under its Guaranty, in bankruptcy or in any other instance (other than the defense of payment or performance in full). When making any demand hereunder or otherwise pursuing its rights and remedies hereunder against either Guarantor, the Holder may, but shall be under no obligation to, join or make a similar demand on or otherwise pursue or exhaust such rights and remedies as it may have against the Maker or any of the other Guarantors, and any failure by the Holder to make any such demand, to pursue such other rights or remedies, or to collect any payments from the Maker or any of the other Guarantors, or any release of the Maker or any of the other Guarantors, shall not relieve such Guarantor of any obligation or liability hereunder, and shall not impair or affect the rights and remedies, whether express, implied, or available as a matter of law, of the Maker against such Guarantor.

	6.		Certain Representations. The Maker hereby represents that: (a) it is duly incorporated, validly existing, and in good standing under the laws of the State of Nevada and has full corporate power and authority to execute and deliver this Note; (b) its execution and delivery of this Note has been duly authorized by all necessary corporate action on its part; (c) as of the time of the execution and delivery of this Note, and after giving effect to the incurrence of the indebtedness and the other transactions contemplated hereby, all representations of the Obligors contained in the Stock Purchase Agreement and the Pledge Agreement are and shall be true and correct and no breach of the obligations of any of the Obligors has occurred under the Stock Purchase Agreement or the Pledge Agreement; and (d) this Note constitutes a legal, valid, and binding obligation of the Maker, enforceable against the Maker in accordance with the terms hereof, except as such enforceability may be limited by: (i) bankruptcy, insolvency, reorganization, fraudulent transfer or conveyance, and other laws of general applicability relating to or affecting creditors’ rights; and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

	7.		Entire Agreement; Assignment. This Note, the Stock Purchase Agreement and the Pledge Agreement constitute the entire agreement and understanding among the Holder and the Obligors with respect to the subject matter of this Note and supersede all prior agreements and understandings, oral or written, among such parties with respect to the subject matter of this Note.

			The Maker may not assign any of its rights or obligations under this Note without the prior written consent of the Holder.

	8.		Notices. All notices and communications provided for hereunder shall be in writing and sent (a) by facsimile if the sender on the same day sends a confirming copy of such notice by a recognized overnight-delivery service (charges prepaid), or (b) by registered or certified mail with return receipt requested (postage prepaid), or (c) by a recognized overnight-delivery service (with charges prepaid).

Upon the occurrence and during the continuance of an Event of Default, the Lender shall have the right, at any time in its discretion and without notice to any of the Pledgors, to irrevocably transfer to or to register in its name or in the name of its nominees any Pledged Collateral. The Lender shall have the right at any time to exchange any certificate or instrument representing or evidencing any Pledged Collateral for certificates or instruments of smaller or larger denominations.

If any sum of money or property so paid or distributed in respect of any Pledged Collateral shall be received by any Pledgor, that Pledgor shall, until such money or property is paid or delivered to the Lender, hold such money or property in trust for the Lender, segregated from other funds of that Pledgor, as additional security for the Secured Obligations.

(c) Except as provided in Article V (Remedial Provisions) or the Stock Purchase Agreement, each Pledgor shall be entitled to exercise all voting, consent and corporate, partnership, limited liability company and similar rights with respect to its Pledged Collateral; provided, however, that no vote shall be cast, consent given or right exercised or other action taken by any Pledgor that would impair the Collateral, result in any violation of any provision of the Stock Purchase Agreement, this Agreement or any other Loan Document.

(d) No Pledgor shall grant “control” (within the meaning of such term under Article 9-106 of the UCC) over any Collateral to any Person other than the Lender.

(e) If any Pledgor is a holder of any Stock or Stock Equivalent in any Person that is an issuer of Stock or Stock Equivalents to be pledged to the Lender under the Stock Purchase Agreement, that Pledgor consents to (i) the exercise of the rights granted to the Lender hereunder (including those described in Section 5.2 (Pledged Collateral)) or under such pledges, and (ii) the pledge by each other Pledgor, pursuant to the terms hereof or the Stock Purchase Agreement, of the Pledged Stock in such Person and to the transfer of such Pledged Stock to the Lender or its nominee and to the substitution of the Lender or its nominee as a holder of such Pledged Stock with all the rights, powers and duties of other holders of Pledged Stock of the same class and, if the Pledgor having pledged such Pledged Stock hereunder had any right, power or duty at the time of such pledge or at the time of such substitution beyond that of such other holders, with all such additional rights, powers and duties. Each Pledgor agrees to execute and deliver to the Lender such certificates, agreements and other documents as may be necessary to evidence, formalize or otherwise give effect to the consents given in this clause (e).

(f) No Pledgor shall, without the consent of the Lender, agree to any amendment of any Constituent Document that in any way adversely affects the perfection of the security interest of the Lender in the Pledged Collateral pledged by that Pledgor hereunder, including any amendment electing to treat any membership interest or partnership interest that is part of the

Pledged Collateral as a “security” under Section 8-103 of the UCC, or any election to turn any previously uncertificated Stock that is part of the Pledged Collateral into certificated Stock.

ARTICLE V REMEDIAL PROVISIONS

Section 5.1 Code and Other Remedies

During the continuance of an Event of Default, the Lender may exercise, in addition to all other rights and remedies granted to it in this Agreement and in any other instrument or agreement securing, evidencing or relating to the Secured Obligations, all rights and remedies of a secured party under the UCC or any other applicable law. Without limiting the generality of the foregoing, the Lender, without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except any notice required by law referred to below) to or upon any Pledgor or any other Person (all and each of which demands, defenses, advertisements and notices are hereby waived), may in such circumstances forthwith collect, receive, appropriate and realize upon any Collateral, and may forthwith sell, lease, assign, give option or options to purchase, or otherwise dispose of and deliver any Collateral (or contract to do any of the foregoing), in one or more parcels at public or private sale or sales, at any exchange, broker’s board or office of the Lender or elsewhere upon such terms and conditions as it may deem advisable and at such prices as it may deem best, for cash or on credit or for future delivery without assumption of any credit risk. The Lender shall have the right upon any such public sale or sales, and, to the extent permitted by the UCC and other applicable law, upon any such private sale or sales, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption of any Pledgor, which right or equity is hereby waived and released. The Lender shall apply the net proceeds of any action taken by it pursuant to this Section 5.1, after deducting all reasonable costs and expenses of every kind incurred in connection therewith or incidental to the care or safekeeping of any Collateral or in any way relating to the Collateral or the rights of the Lender, including reasonable attorneys’ fees and disbursements, to the payment in whole or in part of the Secured Obligations, in such order as the Lender shall prescribe, and only after such application and after the payment by the Lender of any other amount required by any provision of law, need the Lender account for the surplus, if any, to the Pledgors. TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH PLEDGOR WAIVES ALL CLAIMS, DAMAGES AND DEMANDS IT MAY ACQUIRE AGAINST THE LENDER ARISING OUT OF THE EXERCISE BY THE LENDER OF ANY RIGHTS HEREUNDER EXCEPT TO THE EXTENT SUCH LIABILITY IS DETERMINED IN A FINAL, NON-APPEALABLE JUDGMENT IN A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY FROM SUCH PERSON’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. If any notice of a proposed sale or other disposition of Collateral shall be required by law, such notice shall be deemed reasonable and proper if given at least 10 days before such sale or other disposition.

Section 5.2 Pledged Collateral

(a) During the continuance of an Event of Default, upon notice by the Lender to the Pledgors, (i) the Lender shall have the right to receive any Proceeds of the Pledged Collateral and make application thereof to the Secured Obligations in the order determined by the Lender and (ii) the Lender or its nominee may exercise (A) any voting, consent, corporate and other right pertaining to the Pledged Collateral at any meeting of shareholders, partners or members, as the case may be, of the relevant issuer or issuers of Pledged Collateral or otherwise and (B) any right of conversion, exchange and subscription and any other right, privilege or option pertaining to the Pledged Collateral as if it were the absolute owner thereof (including the right to exchange at its discretion any of the Pledged Collateral upon the merger, amalgamation, consolidation, reorganization, recapitalization or other material change in the corporate, limited liability or partnership structure of any issuer of Pledged Stock, the right to deposit and deliver any Pledged Collateral with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Lender may determine), all without liability except to account for property actually received by it; provided, however, that the Lender shall have no duty to any of the Pledgors to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

(b) In order to permit the Lender to exercise the voting and other consensual rights that it may be entitled to exercise pursuant hereto and to receive all dividends and other distributions that it may be entitled to receive hereunder, (i) each Pledgor shall promptly execute and deliver (or cause to be executed and delivered) to the Lender all such proxies, dividend payment orders and other instruments as the Lender may from time to time reasonably request and (ii) without limiting the effect of clause (i) above, each Pledgor hereby grants to the Lender an irrevocable proxy to vote all or any part of the Pledged Collateral and to exercise all other rights, powers, privileges and remedies to which a holder of the Pledged Collateral would be entitled (including giving or withholding written consents of shareholders, partners or members, as the case may be, calling special meetings of shareholders, partners or members, as the case may be, and voting at such meetings), which proxy shall be effective, automatically and without the necessity of any action (including any transfer of any Pledged Collateral on the record books of the issuer thereof) by any other person (including the issuer of such Pledged Collateral or any officer or agent thereof), during the continuance of an Event of Default and which proxy shall only terminate upon the payment in full of the Secured Obligations.

(c) Each Pledgor hereby expressly authorizes and instructs each issuer of any Pledged Collateral pledged hereunder by that Pledgor to (i) comply with any instruction received by it from the Lender in writing that (A) states that an Event of Default has occurred and is continuing and (B) is otherwise in accordance with the terms of this Agreement, without any other or further instructions from that Pledgor, and each Pledgor agrees that such issuer shall be fully protected in so complying and (ii) unless otherwise expressly permitted hereby, pay any dividend or other payment with respect to such Pledged Collateral directly to the Lender.

Section 5.3 Registration Rights

(a) Each Pledgor recognizes that the Lender may be unable to effect a public sale of any Pledged Collateral by reason of certain prohibitions contained in the Securities Act and

applicable state securities laws or otherwise or may determine that a public sale is impracticable or not commercially reasonable and, accordingly, may resort to one or more private sales thereof to a restricted group of purchasers that shall be obliged to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Pledgor acknowledges and agrees that any such private sale may result in prices and other terms less favorable than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The Lender shall be under no obligation to delay a sale of any Pledged Collateral for the period of time necessary to permit the issuer thereof to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if such issuer would agree to do so.

(b) Each Pledgor agrees to use its best efforts to do or cause to be done all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Collateral pursuant to this Section 5.3 valid and binding and in compliance with all other applicable requirements of law; provided that no Pledgor shall be required by the terms of this Agreement to make any kind of filing under the Securities Act, the Exchange Act or any state securities law if the Lender, in its sole discretion, determines that a private sale is practicable and commercially reasonable. Each Pledgor further agrees that a breach of any covenant contained in this Section 5.3 will cause irreparable injury to the Lender, that the Lender has no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section 5.3 shall be specifically enforceable against that Pledgor, and each Pledgor hereby waives and agrees, to the extent permitted by law, not to assert any defense against an action for specific performance of such covenants except for a defense that no Event of Default has occurred.

Section 5.4 Deficiency

The Pledgors shall remain jointly and severally liable for any deficiency if the proceeds of any sale or other disposition of the Collateral are insufficient to pay the Secured Obligations and the reasonable fees and disbursements of any attorney employed by the Lender to collect such deficiency.

Section 5.5 Waivers

Each Pledgor hereby waives any and all rights that it may otherwise have (whether any such right is contractual or exists pursuant to the articles of incorporation or bylaws of any relevant entity or under applicable law) that would breach this Agreement or interfere with the exercise by the Lender of any rights or remedies granted to it pursuant to this Agreement.

ARTICLE VI THE LENDER

Section 6.1 Lender’s Appointment as Attorney-in-Fact

(a) Each Pledgor hereby irrevocably constitutes and appoints the Lender and any officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of that Pledgor and in the name of that Pledgor or in its own name, for the purpose of carrying out the terms of this Agreement,

to take any appropriate action and to execute any document or instrument that may be necessary or desirable to accomplish the purposes of this Agreement, and, without limiting the generality of the foregoing, each Pledgor hereby gives the Lender the power and right, on behalf of that Pledgor, without notice to or assent by that Pledgor, to do any of the following:

(i) in the name of that Pledgor or its own name, or otherwise, take possession of and indorse and collect any check, draft, note, acceptance or other instrument for the payment of moneys due under any account or General Intangible or with respect to any other Collateral and file any claim or take any other action or proceeding in any court of law or equity or otherwise deemed appropriate by the Lender for the purpose of collecting any such moneys due under any account or General Intangible or with respect to any other Collateral whenever payable;

(ii) pay or discharge taxes and Liens levied or placed on or threatened against the Collateral, effect any repair or pay any insurance called for by the terms of this Agreement (including all or any part of the premiums therefor and the costs thereof);

(iii) execute, in connection with any sale provided for in Section 5.1 (Code and Other Remedies) or 5.3 (Registration Rights), any endorsement, assignment or other instrument of conveyance or transfer with respect to the Collateral; or

(iv) (A) direct any party liable for any payment under any Collateral to make payment of any moneys due or to become due thereunder directly to the Lender or as the Lender shall direct, (B) ask or demand for, collect, and receive payment of and receipt for, any moneys, claims and other amounts due or to become due at any time in respect of or arising out of any Collateral, (C) sign and indorse any invoice, draft against debtors, assignment, verification, notice and other document in connection with any Collateral, (D) commence and prosecute any suit, action or proceeding at law or in equity in any court of competent jurisdiction to collect any Collateral and to enforce any other right in respect of any Collateral, (E) defend any suit, action or proceeding brought against that Pledgor with respect to any Collateral, (F) settle, compromise or adjust any such suit, action or proceeding and, in connection therewith, give such discharges or releases as the Lender may deem appropriate, and (G) generally, sell, transfer, pledge and make any agreement with respect to or otherwise deal with any Collateral as fully and completely as though the Lender were the absolute owner thereof for all purposes, and do, at the Lender’s option and the Pledgors’ expense, at any time, or from time to time, all acts and things that the Lender deems necessary to protect, preserve or realize upon the Collateral and the Lender’s security interests therein and to effect the intent of this Agreement, all as fully and effectively as that Pledgor might do.

Anything in this clause (a) to the contrary notwithstanding, the Lender agrees that it shall not exercise any right under the power of attorney provided for in this clause (a) unless an Event of Default shall be continuing.

(b) If any Pledgor fails to perform or comply with any of its agreements contained herein, the Lender, at its option, but without any obligation so to do, may perform or comply, or otherwise cause performance or compliance, with such agreement.

(c) The reasonable expenses of the Lender incurred in connection with actions undertaken as provided in this Section 6.1, together with interest thereon at a rate per annum equal to the rate per annum at which interest would then be payable on past due principal under the Note, from the date of payment by the Lender to the date reimbursed by the Pledgors, shall be jointly and severally payable by the Pledgors to the Lender on demand.

(d) The Pledgors hereby ratify all that said attorneys shall lawfully do or cause to be done by virtue hereof. All powers, authorizations and agencies contained in this Agreement are coupled with an interest and are irrevocable until this Agreement is terminated and the security interests created hereby are released.

Section 6.2 Duty of Lender

The Lender’s sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession shall be to deal with it in the same manner as the Lender deals with similar property for its own account. Neither the Lender, nor any of its respective officers, directors, employees or agents shall be liable for failure to demand, collect or realize upon any Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Pledgor or any other Person or to take any other action whatsoever with regard to any Collateral. The powers conferred on the Lender hereunder are solely to protect the Lender’s interest in the Collateral and shall not impose any duty upon the Lender to exercise any such powers. The Lender shall be accountable only for amounts that it actually receives as a result of the exercise of such powers, and neither the Lender nor any of its respective officers, directors, employees or agents shall be responsible to any Pledgor for any act or failure to act hereunder, except for its own gross negligence or willful misconduct.

Section 6.3 Authorization of Financing Statements

Each Pledgor authorizes the Lender and its affiliates, counsel and other representatives, at any time and from time to time, to file or record financing statements, amendments to financing statements, and other filing or recording documents or instruments with respect to the Collateral in such form and in such offices as the Lender reasonably determines appropriate to perfect the security interests of the Lender under this Agreement. Each Pledgor hereby also authorizes the Lender and its affiliates, counsel and other representatives, at any time and from time to time, to file continuation statements with respect to previously filed financing statements.

Each Pledgor acknowledges that the rights and responsibilities of the Lender under this Agreement with respect to any action taken by the Lender or the exercise or non-exercise by the Lender of any option, voting right, request, judgment or other right or remedy provided for herein or resulting or arising out of this Agreement shall be conclusively presumed to be acting with full and valid authority so to act or refrain from acting, and no Pledgor shall be under any obligation, or entitlement, to make any inquiry respecting such authority.

This Agreement shall be binding upon the successors and assigns of each Pledgor and shall inure to the benefit of the Lender and its successors and assigns; provided, however, that no Pledgor may assign, transfer or delegate any of its rights or obligations under this Agreement without the prior written consent of the Lender. The Lender may transfer or assign this Agreement or any of its rights hereunder to any third party without the consent of any Obligor (including, without limitation, to the administrative or collateral agent for any secured credit facility entered into by the Lender prior to, on or after the date hereof, in connection with the security arrangements relating thereto), and any such transfer or assignment shall be binding on all of the Obligors, and any such assignee of the Lender shall be entitled to enforce all the rights of the Lender hereunder so transferred or assigned to such assignee.

Section 7.5 Counterparts

Signature pages may be detached from multiple counterparts and attached to a single counterpart so that all signature pages are attached to the same document. Delivery of an

executed counterpart by telecopy shall be effective as delivery of a manually executed counterpart.
