Such returns shall be submitted to the Seller no later than 30 Business Days prior to the due date for filing thereof for the Seller’s review and approval, which approval shall not be unreasonably withheld. The Seller shall respond in writing to the Company with any comments within 15 Business Days of receiving the draft Return(s). Failure by the Seller to respond in writing as contemplated in the previous sentence shall indicate the Seller’s approval of such Returns. The Seller, the Buyer and the Company shall consult with each other and attempt in good faith to resolve any issues arising as a result of such Returns and, if they are unable to do so, the disputed items shall be resolved (within a reasonable time, taking into account the deadline for filing such Return) by an internationally recognized independent accounting firm mutually agreed upon by the Buyer and the Seller. Upon resolution of all such items, the relevant Return shall be timely filed on that basis.

(ii)                                  In the event that the Seller is liable for the payment of Taxes pursuant to Section 6.10(a) with respect to any Return that the Buyer has the responsibility to cause to be filed pursuant to this Section 6.10(c), the Seller shall pay to the Company the amount of Taxes on the due date of such Return. No payment pursuant to this Section 6.10(c) shall excuse the Seller from its indemnification obligations pursuant to Section 6.10(a) if the amount of Taxes as ultimately determined (on audit or otherwise) for the periods covered by such Tax Returns and allocable to the Seller pursuant to Section 6.10(a) and Section 6.10(b) exceeds the amount of the Seller’s payment under this Section 6.10(c).

(iii)                               The Buyer (including, after the Closing Date, Intermediate LLC and the Company) shall not amend any Return of the Company for any period prior to the Closing Date without the express written consent of the Seller, which consent shall not be unreasonably withheld or delayed.

(d)                                 The Buyer, the Seller, the Company and each Subsidiary of the Buyer shall reasonably cooperate, and shall cause their respective Affiliates and their respective directors, officers, employees, agents, auditors and authorized representatives reasonably to

35

cooperate, in preparing and filing all Returns and in resolving all disputes and audits with respect to all taxable periods or relating to Taxes, including maintaining and making available to each other all records necessary in connection with Taxes.

(e)                                  (i)                                     If a claim for Taxes, including, without limitation, notice of a pending or threatened audit, shall be made by any taxing authority to the party seeking indemnification (the “Tax Indemnified Party”), which, if successful, could result in an indemnity payment pursuant to this Section 6.10 (a “Tax Claim”), the Tax Indemnified Party shall promptly notify the other party (the “Tax Indemnifying Party”) in writing of the Tax Claim. Such notice will state the nature and basis of the Tax Claim and the amount thereof, to the extent known by the Tax Indemnified Party; provided, however, that failure to give such notice shall not relieve the Tax Indemnifying Party of its obligations under this Section 6.10, except to the extent the Tax Indemnifying Party shall have been prejudiced by such failure.

(ii)                                  The provisions of Section 9.6 relating to third-person claims shall apply to Tax Claims; provided, however, that if a Tax Claim could adversely affect the liability of the Buyer or the Company for Taxes for any period (or portion thereof) after the Closing Date, (1) the Seller shall promptly notify the Buyer of such Tax Claim, (2) the Seller shall keep the Buyer reasonably informed and consult seriously and in good faith with the Buyer and their tax advisors with respect to any issue relating to such Tax Claim, (3) the Seller shall provide the Buyer with copies of all correspondence, notices or other written materials received from any Governmental Authority relating to such Tax Claim and shall otherwise keep the Buyer and their tax advisors apprised of significant developments in the Tax Claim and of significant communications involving representatives of the Governmental Authority prosecuting the Tax Claim, (4) the Seller shall provide the Buyer with a copy of any written submission to be sent to any Governmental Authority pertaining to such Tax Claim prior to the submission thereof and shall give serious and good faith consideration to any comments or suggested revisions that the Buyer or their tax advisors may have with respect thereto, and (5) the Seller shall not be entitled to settle, either administratively or after the commencement of litigation, any Tax Claim described in this Section 6.10(e)(ii) without the prior written consent of the Buyer, not to be unreasonably withheld.

(f)                                    The provisions under this Section 6.10 (and not any other provision in this Agreement) shall govern all indemnity claims with respect to Taxes of the Company. Any claim for indemnification for Taxes under this Section 6.10 shall be brought prior to the Expiration Date.

(g)                                 The Company shall be responsible for all transfer, sales, use, and value added Taxes, if any, arising out of, and all registration or recording fees, if any, applicable to, the Transaction.

(h)                                 The Buyer and the Seller shall treat the Transaction in a manner consistent with “Situation 1” of Revenue Ruling 99-5, 1999-1 C.B. 434. The parties shall treat the debt-funded portion of the Purchase Price (including, without limitation, the Seller’s existing debt deemed to be assumed for federal income tax purposes by Intermediate LLC in the Transaction) as a sale of assets by the Seller to Intermediate LLC pursuant to Section 707(a)(2) of the Code.

36

The Seller shall, within 21 days after the Closing Date, prepare and deliver to the Buyer for its review and approval a schedule that allocates among the assets of the Company that are treated for federal income tax purposes as having been purchased by the Buyer or Intermediate LLC the Purchase Price (as such may be adjusted from time to time and increased by any liabilities that are treated as purchase price for income tax purposes) for such assets as determined for federal income tax purposes. These allocations shall be prepared in accordance with Section 1060 of the Code and the Treasury regulations promulgated thereunder. The Seller and the Buyer shall negotiate in good faith to resolve any disputed items before the Closing Date, and, if they are unable to do so, the disputed items shall be resolved (within a reasonable time, taking into account the Closing Date) by an internationally recognized independent accounting firm mutually agreed upon by the Buyer and the Seller. The Buyer, the Seller, and Intermediate LLC shall file all federal, state, local and foreign Returns in accordance with the allocation agreed to pursuant to this Section 6.10(h) (as such allocation originally proposed or may be revised in accordance with this Agreement, as the case may be) and, except as required pursuant to a final determination (as defined in Section 1313(a) of the Code or corresponding provisions of state or local Law), shall not take, or cause to be taken, any action that would be inconsistent with such allocation in any Tax Return, audit, litigation or otherwise.

(i)                                     The Seller’s obligations pursuant to this Section 6.10 shall expire on the Expiration Date other than with respect to any Tax Claim filed prior to the date thereof, in which case the obligations with respect thereto shall terminate upon resolution of such Tax Claims.

6.11                        Registration and Restructuring.

(a)                                  Between the date of execution of this Agreement and the Closing Date and in any event as soon as practicable after the date of this Agreement, the Company (or an Affiliate of the Company as mutually determined by the Buyer and the Seller) shall file or cause to be filed with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-1 (the “Registration Statement”) relating to the Company’s (or such entity’s) common stock. The Company will keep the Buyer reasonably informed of meetings or conference calls relating to the IPO, including drafting and due diligence sessions, and the Buyer and its representatives may fully participate in such sessions including providing comments to documents and shall be given full access to all working group lists, distributions and other aspects of the IPO process. The law firm of ▇▇▇▇▇▇, ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP will serve as company counsel in connection with preparation of materials related to the IPO. Promptly following the execution of this Agreement, the Buyer shall select the investment bank(s) to serve as underwriter in the IPO, subject to the Seller’s approval (not to be unreasonably withheld or delayed). The Buyer shall have the right to approve the Registration Statement, including all amendments thereto and correspondence with the SEC, which approval shall not be unreasonably withheld or delayed. Subsequent to the Closing, the Buyer shall use its reasonable best efforts to cause the Registration Statement promptly to become effective, and thereafter prepare and file with the SEC such amendments and supplements to the Registration Statement and the prospectus used in connection therewith as may be necessary to keep such registration effective and to comply with the provisions of the Securities Act. The Buyer shall take all reasonable and customary actions to effectuate the IPO.

37

(b)                                 Notwithstanding anything set forth in Section 6.11(a) above, if there shall occur and for the duration of such occurrence, (i) any material adverse change in the financial markets in the United States or any outbreak or escalation of hostilities or other calamity or crisis, the effect of which is such as to make it, in the reasonable judgment of the Buyer, impracticable to market the Company’s securities or to enforce contracts for the sale of the Company’s securities, (ii) a suspension of trading in any securities of the Company on any exchange or in any over-the-counter market, (iii) a suspension or material limitation of trading generally on any of the New York Stock Exchange, the American Stock Exchange, the Nasdaq National Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade or other relevant exchanges, (iv) a declaration of a moratorium on commercial banking activities by either Federal or New York authorities or relevant foreign country authorities, (v) any material disruption in securities settlement, payment or clearance services in the United States, (vi) any material adverse change to the market for securities issued by ethanol producers, or (vii) the Buyer, in its reasonable judgment after reasonable consultation with underwriters and the Seller, believes that market conditions are not favorable based on the performance of recent initial public offerings of other companies, then the Buyer’s obligations set forth in Section 6.11(a) above shall be suspended, provided, however, that the Buyer’s obligation to use its reasonable best efforts to complete the initial public offering of the Company’s securities shall be reinstated when all of such above-stated conditions cease to exist. Notwithstanding any provision of Section 6.11(a) to the contrary, the Buyer shall have no obligation to complete an IPO if the proposed price to the public in such offering would be based on an enterprise value of the Company of less than $1.6 billion (before the application of any IPO discount that may be applied).

6.12                        Non-Competition; Non-Solicitation; Confidentiality.

(a)                                  Each of the Seller and persons set forth on Schedule 6.12(a) of the Disclosure Schedules (each, a “Non-Competition Party”) shall not, directly or indirectly, for the period of time commencing on the Closing Date through the period of time set forth opposite their respective names on Schedule 6.12(a) of the Disclosure Schedules, own, manage, engage in, operate, control, work for, consult with, render services for, do business with, maintain any interest in (proprietary, financial or otherwise) or participate in the ownership, management, operation or control of, any business, whether in corporate, proprietorship or partnership form or otherwise, engaged in the business of constructing, owning or operating corn ethanol plants (the “Restricted Business”); provided, however, that the restrictions contained in this Section 6.12(a) shall not restrict the acquisition by the Seller or a Non-Competition Party, directly or indirectly, of less than 2% of the outstanding capital stock of any publicly traded company engaged in the Restricted Business.

(b)                                 Each of the Seller, each Non-Competition Party and each person set forth on Schedule 6.12(b) of the Disclosure Schedules (each, a “Non-Solicit Party”) agrees it, he or she shall not, and shall cause, if applicable, their directors, officers, employees and Affiliates not to, directly or indirectly, for the period of time commencing on the Closing Date through the period of time set forth opposite their respective names on Schedule 6.12(b) of the Disclosure Schedules:  (i) cause, solicit, induce or encourage any employees of the Company to leave such employment or hire or employ any such individual; or (ii) cause, induce or encourage any material actual or prospective client, customer, supplier, or licensor of the Company (including

38

any existing or former customer of the Company and any Person that becomes a client or customer of the Company after the Closing) or any other Person who has a material business relationship with the Company, to terminate or modify any such actual or prospective relationship.

(c)                                  From and after the Closing Date, Seller, each Non-Competition Party and each Non-Solicit Party agrees that he, she or it shall not and shall cause, if applicable, their directors, officers, employees and Affiliates not to, directly or indirectly, disclose, reveal, divulge or communicate to any Person other than authorized officers, directors and employees of Intermediate LLC or its Subsidiary or use or otherwise exploit for its own benefit or for the benefit of anyone other than Intermediate LLC or its Subsidiary, any Confidential Information (as defined below). Seller, each Non-Competition Party and each Non-Solicit Party agrees he, she or it shall not have any obligation to keep confidential (or cause its officers, directors or Affiliates to keep confidential) any Confidential Information if and to the extent disclosure thereof is specifically required by applicable Law; provided, however, that in the event disclosure is required by applicable Law, such Seller, Non-Competition Party or Non-Solicit Party shall, to the extent reasonably possible, provide the Company with prompt notice of such requirement prior to making any disclosure so that the Company may seek an appropriate protective order. For purposes of this Section 6.12(c), “Confidential Information” means (i) the names or identity of any direct or indirect member of the Seller (a “Member”) and (ii) any information with respect to Intermediate LLC, the Company and its Subsidiary and, including methods of operation, customer lists, products, prices, fees, costs, Technology, inventions, Trade Secrets, know-how, Software, marketing methods, plans, personnel, suppliers, competitors, markets or other specialized information or proprietary matters. “Confidential Information” does not include, and there shall be no obligation hereunder with respect to, information that (i) is generally available to the public on the date of this Agreement or (ii) becomes generally available to the public other than as a result of a disclosure not otherwise permissible hereunder.

(d)                                 The covenants and undertakings contained in this Section 6.12 relate to matters which are of a special, unique and extraordinary character and a violation of any of the terms of this Section 6.12 will cause irreparable injury to Buyer, Intermediate LLC and the Company, the amount of which will be impossible to estimate or determine and which cannot be adequately compensated. Accordingly, the remedy at law for any breach of this Section 6.12 will be inadequate. Therefore, Buyer, the Company and Intermediate LLC will be entitled to a temporary and permanent injunction, restraining order or other equitable relief from any court of competent jurisdiction in the event of any breach of this Section 6.12 without the necessity of proving actual damage or posting any bond whatsoever. The rights and remedies provided by this Section 6.12 are cumulative and in addition to any other rights and remedies which Buyer, the Company and Intermediate LLC may have hereunder or at law or in equity. In the event that Buyer, the Company and Intermediate LLC or were to seek damages for any breach of this Section 6.12, the portion of the consideration delivered to each of the Non-Competition Parties and each of the Non-Solicit Parties hereunder which is allocated by the parties to the foregoing covenant shall not be considered a measure of or limit on such damages.

(e)                                  The parties hereto agree that, if any court of competent jurisdiction determines that a specified time period, a specified geographical area, a specified business limitation or any other relevant feature of this Section 6.12 is unreasonable, arbitrary or against

39

public policy, then a lesser period of time, geographical area, business limitation or other relevant feature which is determined by such court to be reasonable, not arbitrary and not against public policy may be enforced against the applicable party.

(f)                                    Each of Non-Competition Parties and Non-Solicit Parties represent, as to themselves, that they are not currently an owner (other than a passive owner of less than 5% of the equity or debt securities of any Restricted Business), operator, manager, director, employee or consultant of any Restricted Business.

6.13                        Cooperation with Financing. In order to assist with obtaining the debt financing contemplated by the Debt Commitment Letter (the “Financing”), the Seller, Intermediate LLC and the Company shall provide such assistance and cooperation as Buyer and their Affiliates may reasonably request, including (i) preparing any marketing material and cooperating with initial purchasers, (ii) making senior management of the Company reasonably available for customary presentations, lender or proposed financing source meetings and rating agencies presentations, (iii) cooperating with prospective lenders, underwriters, placement agents or initial purchasers and their respective advisors in performing their due diligence, (iv) entering into customary agreements with lenders, and (v) helping procure other definitive financing documents or other reasonably requested certificates or documents, including pledge and security documents, customary certificates (including a certificate of the chief financial officer of the Company with respect to solvency matters), legal opinions and real estate title documentation.

6.14                        Cooperation with IPO. The Seller, Intermediate LLC and the Company shall provide such assistance and cooperation as Buyer and their Affiliates may reasonably request in connection with the initial public offering (“IPO”), including, without limitation, making senior management of the Company reasonably available for “road shows” and meetings with underwriters and cooperating with underwriters and their respective advisors in performing their due diligence.

6.15                        Related-Party Transactions with Non-Management Affiliates. On or prior to the Closing Date, the Company and Intermediate LLC shall (a) terminate all contracts with Seller or its Affiliates and (b) deliver releases executed by such Affiliates with whom the Company has terminated such contracts pursuant to this Section 6.15, providing that no further payments are due, or may become due, under or in respect of any such terminated contacts; provided that in no event shall Intermediate LLC and the Company pay any fee or otherwise incur any expense or financial exposure with respect to any such termination or release.

6.16                        Fairbank/Iowa Construction Expenses. Prior to Closing, the Company shall pay the Fairbank/Iowa Construction Expenses as they become due and payable.

6.17                        Intermediate LLC Formation.

(a)                                  Upon reasonable request of the Buyer, the Seller will form Intermediate LLC as a wholly owned Subsidiary of the Seller, solely for the purpose of consummating the transactions contemplated hereby. Intermediate LLC will not engage in any activity or conduct any other business and will have no assets (other than the membership interests in the Company) and no liabilities other than as provided in, or contemplated by, this Agreement and the

40

transactions contemplated thereby. At Closing, the Seller shall deliver a certificate to Buyer (the “Intermediate LLC Certificate”) representing to Buyer that (i) Seller owns the Membership Interests, representing 100% of the outstanding securities of the Intermediate LLC, free and clear of all liens, claims, charges, pledges, security interests, options or other encumbrances, (ii) the Membership Interests are duly authorized, validly issued, fully paid and nonassessable and are issued in compliance with federal and state securities laws, (iii) there are no outstanding options, warrants, puts or calls or other commitments relating to the issuance, sale or transfer of the Membership Interests, and (iv) the Intermediate LLC is a limited liability company duly organized, validly existing and in good standing under the laws of the State of Delaware.

(d)                                 by either the Seller or the Buyer if the Closing shall not have occurred by July 31, 2006 (the “Termination Date”); provided, that the right to terminate this Agreement under this Section 8.1(d) shall not be available if the failure of the party (in the case of the Seller, including for this purpose the Company) so requesting termination to fulfill any obligation under this Agreement shall have been the cause of the failure of the Closing to occur on or prior to such date; and provided further that if the Closing shall not have occurred as of the Termination Date solely because a curable (within thirty (30) days) event or condition shall have occurred or be existing that causes the failure to satisfy the condition set forth in Section 7.3(e), then the Termination Date shall be extended, to a date not later than August 17, 2006, in order for such condition to be satisfied; or

(e)                                  by either the Seller or the Buyer in the event that any Governmental Authority shall have issued an order, decree or ruling or taken any other action restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and such order, decree, ruling or other action shall have become final and non-appealable; provided, that

45

the party so requesting termination shall have complied with Section 6.7.

The party seeking to terminate this Agreement pursuant to this Section 8.1 (other than Section 8.1(a)) shall give prompt written notice of such termination to the other parties.

8.2                               Effect of Termination.

(a)                                  In the event of the termination of this Agreement pursuant to Section 8.1, this Agreement shall become void and have no effect, without any liability on the part of any party or its members, managers, directors or officers, except (a) for the provisions of Sections 3.6 and 5.5 relating to broker’s fees and finder’s fees, Section 6.6 relating to confidentiality, Section 6.8 relating to public announcements, Section 10.1 relating to notices, Section 10.3 relating to fees and expenses, Section 10.7 relating to third-party beneficiaries, Section 10.8 relating to governing law, Section 10.9 relating to submission to jurisdiction and this Section 8.2. Notwithstanding the foregoing, nothing in this Section 8.2 shall relieve any party hereto of liability for any willful and material breach of any covenant or agreement contained in this Agreement, and if it shall be judicially determined that termination of this Agreement was caused by an intentional breach of any covenant or agreement contained in this Agreement, then, in addition to other remedies at law or equity for breach of this Agreement, the party so found to have intentionally breached any covenant or agreement contained in this Agreement shall indemnify and hold harmless the other party for its costs, fees and expenses of its counsel, accountants, financial advisors, consultants and other experts and advisors as well as fees and expenses incident to negotiation, preparation and execution of this Agreement and related documentation and consents.

(b)                                 In the event that this Agreement is terminated by the Seller pursuant to Section 8.1(d), then the Buyer shall pay $42,500,000 (such amount, the “Termination Fee”) to the Seller as promptly as reasonably practicable (and, in any event, within two (2) business days following such termination), payable by wire transfer of same-day funds.

(c)                                  The Buyer acknowledges that Section 8.2(b) is an integral part of the transactions contemplated by this Agreement and constitute liquidated damages and not a penalty, and that the Seller would not have entered into this Agreement without Section 8.2(b); accordingly, if the Buyer fails to promptly pay any amounts due pursuant to Section 8.2(b) and, in order to obtain such payment, the Seller commences a suit which results in a final, non-appealable judgment or ruling against the Buyer for the fee set forth in Section 8.2(b), the Buyer shall pay to the Seller the Seller’s reasonable costs and expenses (including reasonable attorneys’ fees and expenses of enforcement) in connection with such suit, together with interest on the amounts owed at a per annum rate equal to the prime lending rate charged by Citibank, N.A. at such time for demand loans in U.S. dollars to its most creditworthy customers, plus two percent per annum, from the date such amounts were required to be paid until the date actually received by the Seller.

(d)                                 Notwithstanding anything to the contrary set forth in this Agreement, each of the parties hereto hereby expressly acknowledges and hereby agrees that, with respect to any termination of this Agreement pursuant to Section 8.1(b)(i) (other than a termination based upon the willful or intentional breach of, or any intentional misrepresentation made in, this Agreement,

46

it being acknowledged that failure to obtain the Financing shall not constitute a willful or intentional breach) under circumstances in which the Termination Fee is payable pursuant to Section 8.3(b), payment of the Termination Fee shall constitute liquidated damages with respect to any claim for damages or any other claim which the Seller or the Company would otherwise be entitled to assert against the Buyer or its assets, or against any employees or equityholders of the Buyer, with respect to any such termination of this Agreement, and shall constitute the sole and exclusive remedy with respect to any such termination of this Agreement. The parties hereto expressly acknowledge and agree that, in light of the difficulty of accurately determining actual damages with respect to the foregoing upon any such termination of this Agreement pursuant to Section 8.1(b)(i) (other than a termination based upon the willful or intentional breach of, or any intentional misrepresentation made in, this Agreement, it being acknowledged that failure to obtain the Financing shall not constitute a willful or intentional breach) under circumstances in which the Termination Fee is payable pursuant to Section 8.2(b), the right to such payment: (A) constitutes a reasonable estimate of the damages that will be suffered by reason of any such termination this Agreement, and (B) shall be in full and complete satisfaction of any and all damages arising as a result of any such termination of this Agreement. Except for nonpayment of the Termination Fee pursuant to Section 8.3(b), the parties agree that, upon any termination of this Agreement pursuant to Section 8.1(b)(i) (other than a termination based upon the willful or intentional breach of, or any intentional misrepresentation made in, this Agreement, it being acknowledged that failure to obtain the Financing shall not constitute a willful or intentional breach) under circumstances in which the Termination Fee is payable pursuant to this Section 8.3(b), in no event shall the Seller or the Company be entitled to seek or to obtain any recovery or judgment against the Buyer or any Subsidiary of the Buyer or any of their respective assets, or against any of their respective directors, officers, employees or equityholders for any such termination of this Agreement, and in no event shall the Seller or the Company be entitled to seek or obtain any other damages of any kind, including consequential, special, indirect or punitive damages, for any such termination of this Agreement. Notwithstanding the foregoing, payment of the Termination Fee pursuant to Section 8.3(b) shall not constitute liquidated damages with respect to any claim for damages or any other claim which the Seller or the Company would be entitled to assert against the Buyer or its assets, or against any employees or equityholders of the Buyer, with respect to any such termination of this Agreement based upon the willful or intentional breach or intentional misrepresentation of any representations, warranties or covenants of the Buyer in this Agreement, and shall not constitute the sole and exclusive remedy with respect to any such termination of this Agreement based upon the willful or intentional breach or misrepresentation of any of the representations, warranties or covenants of the Buyer in this Agreement, it being acknowledged that failure to obtain the Financing shall not constitute a willful or intentional breach.

8.3                               Amendment. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

8.4                               Extension; Waiver. At any time prior to the Closing Date, the Buyer (with respect to the Seller and the Company) and the Seller and the Company (with respect to the Buyer) may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of such party, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto, and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the

47

part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party.

ARTICLE IX
INDEMNIFICATION

9.1                               Survival of Representations, Warranties and Covenants. All representations and warranties made by the parties in this Agreement, or in connection with the negotiation, execution and performance of this Agreement, shall survive the Closing until the first anniversary of the Closing Date (the “Expiration Date”), at which time they shall expire; provided, however, that those representations and warranties made by the parties in Sections 3.1 (Organization and Standing), 3.2 (Corporate Power and Authority), 4.1 (Organization and Qualification), 4.2 (Authority), and 4.5 (Membership Interests and Ownership), and 5.1 (Organization), 5.2 (Authorization), 5.4 (Ownership of Membership Interests), 5.6 (Organization), 5.7 (Authorization), and 5.8 (Membership Interests and Ownership) and in the Intermediate LLC Certificate shall survive for the applicable statute of limitations. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or agreement, will not affect the right to indemnification or other remedy based on such representation, warranty, covenant and agreement. Notwithstanding any investigation or audit conducted before or after the Closing Date or the decision of the parties to complete the Closing, each party shall be entitled to rely upon the representations and warranties set forth herein, and none of such representations and warranties shall be deemed waived or modified in any respect by reason of any such investigation or audit. All covenants and agreements contained herein which by their terms contemplate actions or impose obligations following the Closing shall survive the Closing and remain in full force and effect in accordance with their terms.

9.2                               Indemnification

(a)                                  The Seller shall indemnify and hold harmless the Buyer and its Subsidiary and other Affiliates (including, after the Closing Date, Intermediate LLC and the Company) and their respective officers, directors, employees, stockholders, partners and agents (collectively, the “Buyer Indemnified Parties”), from and against all losses, costs, claims, damages, liabilities, expenses (including reasonable attorneys’ and accountant’s fees, costs of suit and costs of appeal), fines and penalties (collectively, “Damages”) incurred by any Buyer Indemnified Party, directly or indirectly, arising out of or relating to (i) any breach or failure to be true of any representation or warranty contained herein (other than those representations and warranties contained in Section 4.15) made by the Seller or the Company as if such representation or warranty was made on the date hereof and as of the Closing Date (other than representations and warranties made as of a specified date, which need be true and correct only as of the specified date) or (ii) except for those covenants in Section 6.1(p) and Section 6.10, the breach or non-performance by the Seller or the Company of any of their covenants or agreements contained herein.

(b)                                 The Buyer shall indemnify and hold harmless the Seller and its Subsidiary and other Affiliates (including, prior to the Closing Date, the Company) and their respective managers, members, officers, directors, employees, stockholders, partners and agents

48

(collectively, the “Seller Indemnified Parties”), from and against all Damages incurred by any Seller Indemnified Party, directly or indirectly, arising out of or relating to (i) any breach or failure to be true of any representation or warranty contained herein made by the Buyer as if such representation or warranty was made on or as of the Closing Date (other than representations and warranties made as of a specified date, which need be true and correct only as of the specified date) or (ii) the breach or non-performance by the Buyer of any of its covenants or agreements contained herein.

(c)                                  The term “Damages” as used in this Article IX is not limited to matters asserted by third parties, but includes Damages incurred or sustained by an indemnified party in the absence of third-party claims. The amount of Damages shall be calculated as further provided in Section 9.7. No party hereto will be liable to another party hereunder for any punitive or special damages, including, without limitation, cost of capital or loss of business reputation, relating to any claim for which such party may be entitled to recover under this Agreement, other than indemnification of amounts paid or payable to third parties in respect of any third-party claim for which indemnification hereunder is required.

9.3                               Limitations on Indemnification.

(a)                                  Notwithstanding any other provision in this Agreement to the contrary, a party shall not be liable to indemnify the other party pursuant to this Article IX until the aggregate of all claims for which indemnity is required to be made hereunder shall exceed $12,500,000 (the “Deductible”) and thereafter, only to the extent further Damages for which indemnification hereunder is sought exceed the Deductible; provided, however, that the aggregate amount of Damages recoverable pursuant to this Article IX shall be limited to $60,000,000 (the “Cap”); provided, however, that the Deductible and Cap shall not apply to Damages related to the failure to be true and correct of any of the representations and warranties set forth in Sections 3.1 (Organization and Standing), 3.2 (Corporate Power and Authority), 4.1 (Organization and Qualification), 4.2 (Authority), and 4.5 (Membership Interests and Ownership), and the Intermediate LLC Certificate and 5.1 (Organization), 5.2 (Authorization), 5.4 (Ownership of Membership Interests), 5.6 (Organization), 5.7 (Authorization), and 5.8 (Membership Interests and Ownership) hereof and provided further, except as otherwise provided in this Agreement, no portion of this Section 9.3 shall apply to any indemnification obligation described in Section 6.10.

(b)                                 Except as otherwise provided in this Agreement, the rights and obligations of the parties with respect to indemnification for any and all Tax matters shall be governed by Section 6.10. Any payments made pursuant to this Article IX or Section 6.10 shall constitute an adjustment to the Purchase Price for Tax purposes and shall be treated as such by the Buyer, the Seller, the Company and Intermediate LLC on their Returns to the extent permitted by Law.

9.4                               Mitigation; Exclusivity of Remedy.

(a)                                  Prior to the assertion of any claims for indemnification under this Article IX, an Indemnified Party (as defined below) shall utilize all reasonable efforts, consistent with normal practices and policies and good commercial practice, to mitigate such Damages; provided that, it is hereby acknowledged that such efforts shall not include any obligation by

49

Buyer to exhaust remedies or commence a lawsuit. Except as provided in Section 6.10, the remedies in this Article IX shall be the exclusive remedies of the parties with respect to any and all matters covered by this Agreement, except for the remedies of specific performance, injunction and other equitable relief; provided, however, that no party hereto shall be deemed to have waived any rights, claims, causes of action or remedies if and to the extent such rights, claims, causes of action or remedies may not be waived under applicable Law, or actual fraud, intentional misrepresentation or active concealment is proven on the part of a party by another party hereto.

(b)                                 The parties agree that any and all indemnification obligations of the Seller hereunder (including obligations under Section 6.10), other than indemnity obligations with respect to Damages related to the failure to be true and correct of any of the representations and warranties set forth in Sections 4.1 (Organization and Qualification), 4.2 (Authority), 5.1 (Organization), and 5.4 (Ownership of Membership Interests) and the Intermediate LLC Certificate, shall be satisfied solely from available amounts of the Indemnity Escrow Fund then on deposit with the Escrow Agent. If the Indemnity Escrow Fund is exhausted or is otherwise unavailable, then the Seller (or, to the extent that the Seller has liquidated assets, the Members, on a several and not joint basis), shall be liable to the Buyer for Damages related to the failure to be true and correct of any of the representations and warranties set forth in Sections 4.1 (Organization and Qualification), 4.2 (Authority), 4.5 (Membership Interests and Ownership), 5.1 (Organization), 5.2 (Authorization) and 5.4 (Ownership of Membership Interests) and the Intermediate LLC Certificate.

(c)                                  For purposes of determining whether there has been a breach of any representation, warranty or covenant and for purposes of calculating Damages hereunder, any materiality or Material Adverse Effect qualifications in the representations, warranties, covenants and agreements shall be disregarded, except with respect to any representation or warranty made by the Company on behalf of or with respect to the Subsidiary.

9.5                               Notice of Claims.

(a)                                  Except with respect to Tax Claims, which shall be governed exclusively by Section 6.10, any Buyer Indemnified Party or Seller Indemnified Party seeking indemnification hereunder (the “Indemnified Party”) shall, within the relevant limitation period provided for in Section 9.1 above, give to the party obligated to provide indemnification to such Indemnified Party (the “Indemnitor”) a notice (a “Claim Notice”) describing in reasonable detail the facts giving rise to any claims for indemnification hereunder and shall include in such Claim Notice (if then known) the amount or the method of computation of the amount of such claim, and a reference to the provision of this Agreement or any agreement, certificate or instrument executed pursuant hereto or in connection herewith upon which such claim is based; provided, that a Claim Notice in respect of any action at law or suit in equity by or against a third Person as to which indemnification will be sought shall be given promptly after the action or suit is commenced and shall be subject to Section 9.6 below; provided, further, that failure to give such notice shall not relieve the Indemnitor of its obligations hereunder, except to the extent it shall have been prejudiced by such failure.

50

(b)                                 An Indemnitor shall have 30 days after the giving of any Claim Notice pursuant hereto to (i) agree to the amount or method of determination set forth in the Claim Notice and to pay such amount to such Indemnified Party in immediately available funds or (ii) provide such Indemnified Party with notice that it disagrees with the claim or the amount or method of determination set forth in the Claim Notice (the “Dispute Notice”). Within 15 days after the giving of the Dispute Notice, a representative of the Indemnitor and the Indemnified Party shall negotiate in a bona fide attempt to resolve the matter. In the event that the controversy is not resolved within 30 days of the giving of the Dispute Notice, the parties shall proceed to binding arbitration pursuant to the following procedures:

(i)                                     Any party may send another party written notice identifying the matter in dispute and invoking the procedures of this Section 9.5. Within 14 days, each party involved in the dispute shall meet at a mutually agreed location in New York, New York, for the purpose of determining whether they can resolve the dispute themselves by written agreement, and, if not, whether they can agree upon a third-party arbitrator to whom to submit the matter in dispute for final and binding arbitration.

(ii)                                  If such parties fail to resolve the dispute by written agreement or agree on the arbitrator within said 14-day period, any such party may make written application to the Judicial Arbitration & Mediation Services, Inc. (“J.A.M.S.”) for the appointment of a panel of three arbitrators (collectively, the “Arbitrators”) to resolve the dispute by arbitration. At the request of J.A.M.S., the parties involved in the dispute shall meet with J.A.M.S. at its offices within ten days of such request to discuss the dispute and the qualifications and experience which each party respectively believes the Arbitrators should have; provided, however, that the selection of the Arbitrators shall be the exclusive decision of J.A.M.S. and shall be made within 30 days of the written application to J.A.M.S.

(iii)                               Within 120 days of the selection of the Arbitrators, the parties involved in the dispute shall meet in New York, New York, with such Arbitrators at a place and time designated by such Arbitrators after consultation with such parties and present their respective positions on the dispute. The arbitration proceeding shall be held in accordance with the rules for commercial arbitration of J.A.M.S. in effect on the date of the initial request for appointment of the Arbitrators (as such rules are modified by the terms of this Agreement or may be further modified by mutual agreement of the parties). Each party shall have no longer than five days to present its position, the entire proceedings before the Arbitrators shall be no more than ten consecutive days, and the decision of the Arbitrators shall be made in writing no more than 30 days following the end of the proceeding. Such an award shall be a final and binding determination of the dispute and shall be fully enforceable as an arbitration decision in any court having jurisdiction and venue over such parties. The prevailing party (as determined by the Arbitrators) shall in addition be awarded by the Arbitrators such party’s own attorneys’ fees and expenses in connection with such proceeding. The non-prevailing party (as determined by the Arbitrators) shall pay the Arbitrators’ fees and expenses.

9.6                               Third-Person Claims. If a claim by a third Person is made against an Indemnified Party, and if such party intends to seek indemnity with respect thereto under this

51

Article IX, such Indemnified Party shall promptly notify the Indemnitor in writing of such claims, setting forth such claims in reasonable detail. The Indemnitor shall have 20 days after receipt of such notice to undertake, conduct and control, through counsel of its own choosing and at its own expense, the settlement or defense thereof, and the Indemnified Party shall cooperate with it in connection therewith; provided, that the Indemnified Party may participate in such settlement or defense through counsel chosen by such Indemnified Party and paid at its own expense; provided, further, that, if in the reasonable opinion of counsel for such Indemnified Party, there is a reasonable likelihood of a conflict of interest between the Indemnitor and the Indemnified Party, the Indemnitor shall be responsible for the reasonable fees and expenses of one counsel to such Indemnified Party in connection with such defense. So long as the Indemnitor is reasonably contesting any such claim in good faith, the Indemnified Party shall not pay or settle any such claim without the consent of the Indemnitor. If the Indemnitor does not notify the Indemnified Party within ten days after receipt of the Indemnified Party’s notice of a claim of indemnity under this Section 9.6 that it elects to undertake the defense thereof, the Indemnified Party shall have the right to undertake, at Indemnitor’s cost, risk and expense, the defense, compromise or settlement of the claim, but shall not thereby waive any right to indemnity therefore pursuant to this Agreement. The Indemnitor shall not, except with the consent of the Indemnified Party, enter into any settlement that does not include as an unconditional term thereof the giving by the Person or Persons asserting such claim to all Indemnified Parties of an unconditional release from all liability with respect to such claim or consent to entry of any judgment.

9.7                               Calculation of Damages.

(a)                                  The amount of any Damage for which indemnification is provided under this Article IX shall be (i) with respect to the Company, net of any reserves, liability accruals or other provisions for such Damages on the balance sheet of the Company as of the Closing Date and (ii) net of any amounts recovered by the Indemnified Party under insurance policies with respect to such Damage. In the event that any claim for indemnification asserted hereunder is, or may be, the subject of any insurance coverage or other right to indemnification or contribution from any third Person, the Indemnified Party expressly agrees to promptly notify the applicable insurance carrier of any such claim or loss and tender defense thereof to such carrier, and shall also promptly notify any potential third party indemnitor or contributor which may be liable for any portion of such losses or claims. The Indemnified Party agrees to pursue, at the cost and expense of the Indemnitor, such claims diligently and to reasonably cooperate, at the cost and expense of the Indemnitor, with each applicable insurance carrier and third party indemnitor or contributor. The Indemnified Party shall use its commercially reasonable efforts to seek recoveries under insurance policies and shall reimburse the Indemnitor for any Damage indemnified by them, which is subsequently recovered by the Indemnified Party under any such insurance.

(b)                                 The amount of any Damage (including Taxes) for which indemnification is provided shall be reduced to take account of any net Tax benefit actually recognized by the Indemnified Party arising from the incurrence or payment of any such Damage. In computing the amount of any such Tax benefit, the Indemnified Party shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the

52

receipt of any indemnity payment hereunder or the incurrence or payment of any indemnified Damage.

SCHEDULE 2.1

ADJUSTMENT OF PURCHASE PRICE

(a)                                  At least five (5) Business Days prior to the Closing Date, the Seller shall prepare and deliver to the Buyer a statement (the “Closing Statement”) setting forth a reasonably detailed calculation of the estimated Working Capital of the Company as of the Closing Date prepared in accordance with (A) the books and records of the Company and (B) the Working Capital Accounting Principles. Seller shall grant Buyer and its Affiliates and representatives (including advisors and accountants) access to all books, records and employees of the Company (in each case, only those portions or aspects as they relate solely to the Company) that is reasonably requested by the Buyer in connection with the Seller’s preparation of estimated Working Capital. The Buyer and Seller shall negotiate and cooperate in good faith to agree upon the estimated Working Capital as of the Closing Date. If (A) Seller and Buyer agree on the estimated Working Capital and (B) the estimated Working Capital is less than the Target Working Capital Amount, then the Purchase Price payable at Closing shall be reduced by such shortfall (such amount being the “Closing Date Adjustment”) and no further post-Closing adjustment based on Working Capital shall be made. If (A) Seller and Buyer agree on estimated Working Capital and (B) the estimated Working Capital is greater than the Target Working Capital Amount, then no adjustment to the Purchase Price shall be made at Closing and no further post-Closing adjustment based on Working Capital shall be made.

(b)                                 If the Seller and Buyer cannot agree upon the estimated Working Capital prior to Closing, then the Closing Date Adjustment shall be based on the Seller’s estimated Working Capital and the procedures set forth below in clauses (c)-(h) shall take place

(c)                                  The Seller and the Buyer shall refer any items which are in dispute (“Disputed Items”) to an accountant who is a partner at a nationally recognized firm of independent accountants (the “Accounting Referee”), within five (5) days after acceptance of appointment by the Accounting Referee, to make a final, non-appealable and binding determination as to such remaining Disputed Items pursuant to the terms hereof. The Accounting Referee shall be selected by mutual agreement of the Buyer and the Seller; provided in the event that no Accounting Referee is appointed pursuant to the preceding provision within fifty (50) days of the Closing Date, the Seller and the Buyer shall each, within sixty (60) days of the Closing Date, select an accountant who is a partner at a nationally recognized firm of independent public accountants, who shall be directed to select, within seventy (70) days of the Closing Date, a third accountant who is a partner at a nationally recognized firm of independent public accountants to serve as the Accounting Referee; provided further that any Accounting Referee appointed pursuant to this sentence shall be a certified public accountant or accounting expert with substantial experience with complex financial transactions of the type set forth in the Agreement. The Accounting Referee shall be directed to make a determination in accordance with paragraph (d) below of the Disputed Items promptly, but no later than sixty (60) days, after acceptance of its appointment. The Seller and the Buyer agree to use their commercially reasonable efforts to effect the selection and appointment of the Accounting Referee pursuant to this paragraph (c), including, without limitation, executing an engagement agreement with the Accounting Referee providing for reasonable and customary compensation and other terms of such engagement. The Seller and the

1

Buyer shall make readily available to the Accounting Referee all relevant books, records and employees of the Company that are reasonably requested by the Accounting Referee in connection with the Accounting Referee’s review of any Disputed Items; provided that the Seller, the Buyer and their respective Affiliates shall not be obligated to provide any information the disclosure of which would jeopardize any privilege available to such Person relating to such information or which would cause such Person to breach a confidentiality obligation to which it is bound; and provided further that the Seller, the Buyer and their respective Affiliates shall use their commercially reasonable efforts to minimize the effects of any such limitations.

(d)                                 If Disputed Items are referred to the Accounting Referee for resolution pursuant to paragraph (d) above, the Accounting Referee (i) shall determine only with respect to the Disputed Items submitted whether and to what extent, if any, the Working Capital of the Company as of the Closing Date set forth in the Closing Statement requires adjustment, (ii) shall utilize the Working Capital Accounting Principles without modification and (iii) shall not assign a value to any item greater than the greatest value for such item claimed by either party or less than the smallest value for such item claimed by either party. Any finding by the Accounting Referee shall be a reasoned award stating in reasonable detail the findings of fact (if any) on which it is based, shall be final, non-appealable and binding upon the parties and shall be the sole and exclusive remedy between the parties regarding the Disputed Items so presented. The fees and expenses of the Accounting Referee shall be borne by the Seller and the Buyer in the same proportion that the dollar amount of Disputed Items which are not resolved in favor of the Seller or the Buyer (as applicable) bears to the total dollar amount of Disputed Items resolved by the Accounting Referee. For illustration purposes only, (A) if the total amount of Disputed Items by the Seller is $1,000, and the Seller is awarded $500 by the Accounting Referee, the Seller and the Buyer shall bear the Accounting Referee’s fees and expenses equally; or (B) if the total amount of Disputed Items by the Seller is $1,000, and the Seller is awarded $750 by the Accounting Referee, the Seller shall bear twenty five percent (25%) and the Buyer shall bear seventy five percent (75%) of the Accounting Referee’s fees and expenses. Each of the Seller and the Buyer shall bear the fees, costs and expenses of its own accountants and all of its other expenses incurred in connection with matters contemplated by this Schedule 2.1.

(e)                                  The Working Capital of the Company as of the Closing Date as finally determined by the Accounting Referee under Section (d) above, shall be the “Final Working Capital.”

(f)                                    The “Closing Date Adjustment” shall be recalculated using the Final Working Capital instead of the estimated Working Capital. If the recalculated Closing Date Adjustment (using Final Working Capital) exceeds the Closing Date Adjustment made at Closing, then Buyer shall pay to Seller such excess. If the recalculated Closing Date Adjustment (using Final Working Capital) is less than the Closing Date Adjustment made at Closing, then Seller shall pay to Buyer such shortfall. Any such payment under this Section (f) shall be deemed the “True-Up Amount.”

(g)                                 Payment of the True-up Amount calculated pursuant to this Schedule 2.1 shall be made within ten (10) days following final resolution of all Disputed Items by the parties or the Accounting Referee, by wire transfer of immediately avaiable funds to an account designated

2

by the parties receiving such funds, plus interest thereon from and including the Closing Date through and including the day before the date of such payment, at a per annum rate equal to the prime lending rate charged by Citibank, N.A. as at the Closing Date for demand loans in U.S. dollars to its most creditworthy customers.

Working Capital Accounting Principles

The following Working Capital Accounting Principles shall be used in preparing the Closing Working Capital Worksheet and the Closing Statement:

All terms set forth in the Working Capital Worksheet are defined, recognized, measured and estimated consistently with the use on the balance sheet of the Company in the interim consolidated 2006 financial statements of the Company. For purposes of the calculation of the Closing Working Capital Worksheet above, line item amounts shall be presented on a basis consistent with the accounting principles, measurement methodologies and estimation procedures applied by the Company in presenting the balance sheet in the interim consolidated 2006 financial statements of the Company, notwithstanding any changes to GAAP that have become effective subsequent to March 31, 2006.

The underlying balance sheet components of Estimated Working Capital shall, subject to the immediately succeeding paragraph, be determined in accordance with GAAP, as in effect at March 31, 2006, applied in a manner consistent with the accounting principles and practices used in the determination of the Working Capital as of March 31, 2006. No reserves shall exist with respect to such balance sheet components for purposes of the calculations contemplated herein.

To the extent that (i) there exists any conflict between GAAP and the historical methods and practices used by the Company in the preparation of its related financial statements or (ii) GAAP would otherwise yield a different result than would occur using the historical methods and practices of the Company, the historical methods and practices of the Company shall be applied and shall supersede GAAP.

For the avoidance of doubt, if and to the extent an item of Net Debt, unpaid Transaction Expenses or unpaid Fairbank/Iowa Construction Expenses are otherwise reflected in the calculation of the Purchase Price, no such item shall be counted or reflected in the determination of Working Capital.

In preparation of the estimated Working Capital, the following accounting principles shall be utilized with regard to specific line items:

A new current liability can be established for a new event or for changes in circumstance arising after March 31, 2006 and before the Closing Date, however, the respective amounts included in the Estimated Working Capital shall not include any reserves.
