CONVERSION OF SECURITIES

Section 2.1             Conversion of Units. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any membership unit of IRF (“IRF Units”) or units of Merger Sub:

(a)           Units of Merger Sub. Each issued and outstanding unit of Merger Sub shall be converted into and become one fully paid and nonassessable unit of the Surviving Company.

(b)           Cancellation of ABE-Owned and IRF-Owned Units. Any IRF Units that are owned by ABE, Merger Sub or IRF shall be canceled and retired and shall cease to exist and no unit of ABE or other consideration shall be delivered in exchange.

(c)           Conversion of IRF Units. Subject to Sections 2.2 and 2.5, each issued and outstanding IRF Unit (other than IRF Units to be canceled in accordance with Section 2.1(b) shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into, at the election of each individual holder of IRF Units, the right to receive either: (A) 500 fully paid and nonassessable of ABE Units; or (B) $5,000 in cash; provided, that in the aggregate, IRF’s members must elect to receive at least 250,000 ABE Units. All such IRF Units, when so converted, shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such IRF Units shall cease to have any rights with respect thereto, except the right to receive ABE Units or cash in consideration therefor upon the surrender of such certificate in accordance with Section 2.3. For purposes of this Agreement, “ABE Unit” means one membership unit of ABE.

Section 2.2             Escrow Agreement. At the Effective Time, ABE will, on behalf of the holders of IRF Units, withhold 75,000 ABE Units issuable to such holders pursuant to Section 2.1 of this Agreement (such ABE Units, the “Escrow Amount”). The Escrow Amount shall be held in escrow on behalf of the persons who are the holders of IRF Units immediately prior to the Effective Time (the “Former IRF Unitholders”), in accordance with each Former IRF Unitholder’s Pro Rata Share (as defined below). The Escrow Amount shall be held and applied pursuant to the provisions of this Agreement and an escrow agreement in the form attached hereto as Exhibit C (the “Escrow Agreement”). “Pro Rata Share” means, with respect to any Former IRF Unitholder, the fraction

2

obtained by dividing (A) the number of ABE Units placed in escrow on behalf of the Former IRF Unitholder by (B) the Escrow Amount.

Section 2.3             Exchange of Certificates.

(a)           From and after the Effective Time, each holder of an outstanding certificate or certificates (“Certificates”) that represented IRF Units immediately prior to the Effective Time shall have the right to surrender each Certificate to ABE (or at ABE’s option, an exchange agent to be appointed by ABE) and, in exchange for all Certificates held by such holder, to receive, as soon as reasonably practicable following the surrender of such Certificates, cash or a certificate representing the number of ABE Units into which the IRF Units evidenced by the Certificates so surrendered shall have been converted pursuant to the provisions of Section 2.1 of this Agreement. The surrender of Certificates shall be accompanied by duly completed and executed Letters of Transmittal in such form as may be reasonably specified by ABE. Until surrendered, each outstanding Certificate, which prior to the Effective Time represented IRF Units, shall be deemed for all corporate purposes to evidence ownership of cash or number of ABE Units into which the IRF Units have been converted but shall have no other rights. From and after the Effective Time, the holders of IRF Units shall cease to have any rights in respect of such units and their rights shall be solely in respect of the cash or ABE Units into which such IRF Units have been converted. From and after the Effective Time, there shall be no further registration of transfers on the records of IRF of IRF Units outstanding immediately prior to the Effective Time.

(b)           If any ABE Units are to be issued in the name of a person other than the person in whose name the Certificate(s) surrendered in exchange therefor is registered, it shall be a condition to the issuance of such ABE Units that (i) the Certificate(s) so surrendered shall be transferable, and shall be properly assigned, endorsed or accompanied by appropriate stock powers, (ii) such transfer shall otherwise be proper and (iii) the person requesting such transfer shall pay ABE, or its exchange agent, any transfer or other taxes payable by reason of the foregoing or establish to the satisfaction of ABE that such taxes have been paid or are not required to be paid. Notwithstanding the foregoing, neither ABE nor IRF shall be liable to a holder of IRF Units for ABE Units issuable to such holder pursuant to the provisions of Article II of this Agreement that are delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(c)           In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, ABE shall issue in exchange for such lost, stolen or destroyed Certificate the cash or ABE Units issuable in exchange therefor pursuant to the provisions of Article II of this Agreement. The board of directors of ABE may in its discretion and as a condition precedent to the issuance thereof, require the owner of the lost, stolen or destroyed Certificate to provide to ABE an indemnity agreement or bond against any claim that may be made against ABE with respect to the Certificate alleged to have been lost, stolen or destroyed.

Section 2.4             Distributions with Respect to Unexchanged Units. No dividends or other distributions declared or made after the Effective Time with respect to ABE Units with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the ABE Units represented thereby until the holder of record of such Certificate shall surrender such Certificate. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing ABE Units issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any dividends or other distributions with a record date after the Effective Time previously paid with respect to such ABE Units, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such ABE Units.

3

Section 2.5             No Fractional Units. No certificate or scrip representing fractional ABE Units shall be issued upon the surrender for exchange of Certificates, and such fractional unit interests will not entitle the owner thereof to vote or to any rights of a unitholder of ABE. Notwithstanding any other provision of this Agreement, each holder of IRF Units exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a ABE Unit (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fraction of a ABE Unit multiplied by $10.00.

Section 2.6             Required Withholding. Each of ABE, Merger Sub and any exchange agent that may be appointed by ABE shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of IRF Units such amounts as may be required to be deducted or withheld therefrom under the Internal Revenue Code of 1986 or under any provision of state, local or foreign Tax law or under any other applicable law. To the extent such amounts are so deducted or withheld, such amount shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid.

Section 3.5             Tax Matters.

(a)           For purposes of this Agreement, the following definitions shall apply:

(i)            The term “Taxes” shall mean all taxes, however denominated, including any interest, penalties or other additions to tax that may become payable in respect thereof, (A) imposed by any federal, territorial, state, local or foreign government or any agency or political subdivision of any such government, which taxes shall include, without limiting the generality of the foregoing, all income or profits taxes (including but not limited to, federal income taxes and state income taxes), payroll and employee withholding taxes, unemployment insurance, social security taxes, sales and use taxes, ad valorem taxes, excise taxes, franchise taxes, gross receipts taxes, business license taxes, occupation taxes, real and personal property taxes, stamp taxes, environmental taxes, ozone depleting chemicals taxes, transfer taxes, workers’ compensation, Pension Benefit Guaranty Corporation premiums and other governmental charges, and other obligations of the same or of a similar nature to any of the foregoing, which are required to be paid, withheld or collected, (B) any liability for the payment of amounts referred to in (A) as a result of being a member of any affiliated, consolidated, combined or unitary group, or (C)

6

(ii)           The term “Returns” shall mean all reports, estimates, declarations of estimated tax, information statements and returns relating to, or required to be filed in connection with, any Taxes, including information returns or reports with respect to backup withholding and other payments to third parties.

(b)           All Returns required to be filed prior to the date hereof by or on behalf of IRF have been duly filed on a timely basis, and such Returns are true, complete and correct in all material respects. All Taxes shown to be payable on such Returns or on subsequent assessments with respect thereto, and all payments of estimated Taxes required to be made prior to the date hereof by or on behalf of IRF have been paid in full on a timely basis and no other Taxes are payable by IRF with respect to items or periods covered by such Returns (whether or not shown on or reportable on such Returns). IRF has withheld and paid over all Taxes required to have been withheld and paid over prior to the date hereof, and complied with all information reporting and backup withholding requirements, including maintenance of required records with respect thereto, in connection with amounts paid or owing to any employee, creditor, independent contractor or other third party. To its knowledge, IRF has received, from each employee who holds IRF Units that are subject to a substantial risk of forfeiture as of the date hereof, a copy of the election(s) made under Section 83(b) of the Code with respect to all such IRF Units, and such elections were validly made and filed with the Internal Revenue Service in a timely fashion. There are no liens on any of the assets of IRF with respect to Taxes, other than liens for Taxes not yet due and payable or for Taxes that IRF is contesting in good faith through appropriate proceedings and for which appropriate reserves have been established on the IRF Balance Sheet. IRF has not at any time been (i) a member of an affiliated group of companies filing consolidated, combined or unitary income or franchise tax returns, or (ii) a member of any partnership or joint venture for a period for which the statue of limitations for any Tax potentially applicable as a result of such membership has not expired.

(c)           The amount of IRF’s liability for unpaid Taxes (whether actual or contingent) for all periods through the date of the IRF Balance Sheet does not, in the aggregate, exceed the amount of the current liability accruals for Taxes reflected on the IRF Balance Sheet, and the IRF Balance Sheet reflects proper accrual in accordance with generally accepted accounting principles applied on a basis consistent with prior periods of all liabilities for Taxes payable after the date of the IRF Balance Sheet attributable to transactions and events occurring prior to such date. No material amount of taxable income or liability for Taxes has been realized or incurred (or prior to and including the Effective Time will be realized or incurred) since such date other than in the ordinary course of business.

IRF does not do business in or derive income from any state other than states for which Returns have been duly filed and furnished to ABE.

(e)           The Returns of or including IRF have never been audited by a government or taxing authority, nor is any such audit in process, pending or, to IRF’s knowledge, threatened (either in writing or verbally, formally or informally). No deficiencies exist or have been asserted (either in writing or verbally, formally or informally), and IRF has not received notice (either in writing or verbally, formally or informally) that it has not filed a Return or paid Taxes required to be filed or paid. IRF is neither a party to any action or proceeding for assessment or collection of Taxes, nor has such event been asserted or threatened (either in writing or orally, formally or informally) against IRF or any of its assets. No waiver or extension of any statute of limitations is in effect with respect to Taxes or

7

Returns of IRF. IRF has disclosed on its federal and state income and franchise tax Returns all positions taken therein that could give rise to a substantial understatement penalty or comparable provisions of applicable state, local, foreign or other tax laws.

(f)            Except as may be required as a result of the Merger, IRF and its subsidiaries have not been and will not be required to include any material adjustment in Taxable income for any Tax period (or portion thereof) or any comparable provision under state or foreign Tax laws as a result of transactions, events or accounting methods employed prior to the Closing.

(g)           IRF is not, nor has it ever been, a party to any tax sharing agreement.

(h)           IRF is not, nor has it been, a United States real property holding corporation within the meaning of Section 897(c)(2) of the Code during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code, and ABE is not required to withhold tax by reason of Section 1445 of the Code. IRF is not a “consenting corporation” under Section 341(f) of the Code. IRF has not entered into any compensatory agreements with respect to the performance of services which payment thereunder would result in a nondeductible expense to IRF pursuant to Section 280G of the Code or an excise tax to the recipient of such payment pursuant to Section 4999 of the Code. IRF has not agreed to, nor is it required to make any adjustment under Code Section 481(a) by reason of, a change in accounting method. IRF is not, nor has it been, a “reporting corporation” subject to the information reporting and record maintenance requirements of Section 6038A and the regulations thereunder. IRF is in compliance with the terms and conditions of any applicable tax exemptions, agreements or orders of any foreign government to which it may be subject or which it may have claimed, and the transactions contemplated by this Agreement will not have any adverse effect on such compliance.

(i)            IRF has not constituted either a “distributing corporation” or a “controlled corporation” in a distribution of IRF Units intended to qualify for tax-free treatment under Section 355 of the Code.

No claims have been asserted or threatened against IRF (and IRF is not aware of any claims which are likely to be asserted or threatened against IRF or which have been asserted or threatened against others relating to IRF Proprietary Rights or IRF’s products) by any person challenging IRF’s use, possession, manufacture, sale or distribution of IRF products under any IRF Proprietary Rights (including, without limitation, the Third Party Technology) or challenging or questioning the validity or effectiveness of any material license or agreement relating thereto (including, without limitation, the Third Party Licenses) or alleging a violation of any person’s or entity’s privacy, personal or

10

confidentiality rights. None of IRF’s products nor the use or exploitation of any IRF Proprietary Rights or the Third Party Technology in IRF’s current business infringes on the rights of or constitutes misappropriation of any proprietary information or intangible property right of any third person or entity, including without limitation any patent, trade secret, copyright, trademark or trade name, and IRF has not been sued or named in any suit, action or proceeding which involves a claim of such infringement, misappropriation or unfair competition.

(b)           To IRF’s knowledge, no employee, contractor or consultant of IRF is in violation in any material respect of any term of any written employment contract, patent disclosure agreement or any other written contract or agreement relating to the relationship of any such employee, consultant or contractor with IRF or, to IRF’s knowledge, any other party because of the nature of the business conducted by IRF or proposed to be conducted by IRF. The IRF Disclosure Schedule lists all employees, contractors and consultants who have participated in any way in the development of any material portion of the IRF Proprietary Rights.

(c)           Each person presently or previously a member of IRF has executed a confidentiality agreement pursuant to the form of agreement previously provided to ABE or its representatives.

Section 3.9             Employee Benefit Plans.

(a)           The IRF Disclosure Schedule lists, with respect to IRF and any trade or business (whether or not incorporated) that is treated as a single employer with IRF (an “ERISA Affiliate”) within the meaning of Section 414(b), (c), (m) or (o) of the Code, (i) all employee benefit plans (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) each loan to a non-officer employee, loans to officers and directors and any unit option,

11

unit purchase, phantom unit, unit appreciation right, supplemental retirement, severance, sabbatical, medical, dental, vision care, disability, employee relocation, cafeteria benefit (Code Section 125) or dependent care (Code Section 129), life insurance or accident insurance plans, programs or arrangements, (iii) all bonus, pension, profit sharing, savings, deferred compensation or incentive plans, programs or arrangements, (iv) other fringe or employee benefit plans, programs or arrangements that apply to senior management of IRF and that do not generally apply to all employees, and (v) any current or former employment or executive compensation or severance agreements, written or otherwise, for the benefit of, or relating to, any present or former employee, consultant or director of IRF as to which (with respect to any of items (i) through (v) above) any potential liability is borne by IRF (together, the “IRF Employee Plans”).

(b)           IRF has delivered to ABE or its representatives a copy of each of the IRF Employee Plans and related plan documents (including trust documents, insurance policies or contracts, employee booklets, summary plan descriptions and other authorizing documents, and, to the extent still in its possession, any material employee communications relating thereto) and has, with respect to each IRF Employee Plan that is subject to ERISA reporting requirements, provided copies of any Form 5500 reports filed. Any IRF Employee Plan intended to be qualified under Section 401(a) of the Code has either obtained from the Internal Revenue Service a favorable determination, notification or opinion letter as to its qualified status under the Code, including all amendments to the Code effected by the Tax Reform Act of 1986 and subsequent legislation, or has applied to the Internal Revenue Service for such a determination, notification or opinion letter prior to the expiration of the requisite period under applicable Treasury Regulations or Internal Revenue Service pronouncements in which to apply for such letter and to make any amendments necessary to obtain a favorable determination as to its qualified status from the date of adoption. IRF has also furnished ABE with the most recent Internal Revenue Service letter issued with respect to each such IRF Employee Plan, and nothing has occurred since the issuance of each such letter which could reasonably be expected to cause the loss of the tax-qualified status of any IRF Employee Plan subject to Code Section 401(a).

(c)           (i) None of the IRF Employee Plans promises or provides retiree medical or other retiree welfare benefits to any person (other than as required under applicable statutory law or regulation); (ii) there has been no “prohibited transaction,” as such term is defined in Section 406 of ERISA and Section 4975 of the Code, with respect to any IRF Employee Plan; (iii) each IRF Employee Plan has been administered in accordance with its terms and in compliance with the requirements prescribed by any and all statutes, rules and regulations (including ERISA and the Code), and IRF and each subsidiary or ERISA Affiliate have performed all material obligations required to be performed by them under, are not in any material respect in default, under or violation of, and have no knowledge of any material default or violation by any other party to, any of the IRF Employee Plans; (iv) neither IRF nor any subsidiary or ERISA Affiliate is subject to any liability or penalty under Sections 4976 through 4980 of the Code or Title I of ERISA with respect to any of the IRF Employee Plans; (v) all contributions required to be made by IRF or any subsidiary or ERISA Affiliate to any IRF Employee Plan have been made on or before their due dates and a reasonable amount has been accrued for contributions to each IRF Employee Plan for the current plan years; (vi) with respect to each IRF Employee Plan, no “reportable event” within the meaning of Section 4043 of ERISA (excluding any such event for which the 30 day notice requirement has been waived under the regulations to Section 4043 of ERISA) nor any event described in Section 4062, 4063 or 4041 of ERISA has occurred; and (vii) no IRF Employee Plan is covered by, and neither IRF nor any subsidiary or ERISA Affiliate has incurred or expects to incur any material liability under Title IV of ERISA or Section 412 of the Code. With respect to each IRF Employee Plan subject to ERISA as either an employee pension plan within the meaning of Section 3(2) of ERISA or an employee welfare benefit plan within the meaning of Section 3(1) of ERISA, IRF has prepared in good faith and timely filed all requisite governmental reports (which were true and correct as of the date filed) and has properly and timely filed and distributed or posted all notices and reports to

12

participants required to be filed, distributed or posted with respect to each such IRF Employee Plan. No suit, administrative proceeding, action or other litigation has been brought, or to the knowledge of IRF is threatened, against or with respect to any such IRF Employee Plan, including any audit or inquiry by the IRS or United States Department of Labor. Neither IRF nor any ERISA Affiliate is a party to, or has made any contribution to or otherwise incurred any obligation under, any “multi-employer plan” as defined in Section 3(37) of ERISA or any plan maintained by more than one unrelated employer (a “multiple employer plan”).

(e)           The consummation of the transactions contemplated by this Agreement will not (i) entitle any current or former employee or other service provider of IRF or any other ERISA Affiliate to severance benefits or any other payment (including, without limitation, unemployment compensation, golden parachute or bonus), except as expressly provided in this Agreement, or (ii) accelerate the time of payment or vesting of any such benefits, or (iii) increase or accelerate any benefits or the amount of compensation due any such employee or service provider.

(f)            There has been no amendment to, written interpretation or announcement (whether or not written) by IRF or other ERISA Affiliate relating to, or change in participation or coverage under, any IRF Employee Plan which would materially increase the expense of maintaining such Plan above the level of expense incurred with respect to that Plan for the most recent fiscal year included in the IRF Financial Statements. No IRF Employee Plan will be subject to any surrender fees or services fees upon termination other than the normal and reasonable administrative fees associated with the termination of benefit plans.

(g)           The IRF Disclosure Schedule lists all “nonqualified deferred compensation plans” (within the meaning of Section 409A of the Code) to which IRF is a party. Each such nonqualified deferred compensation plan to which IRF is a party complies with the requirements of paragraphs (2), (3) and (4) of Section 409A(a) by its terms and has been operated in accordance with such requirements.

Notwithstanding the foregoing, none of ABE, Merger Sub or IRF makes any representation or warranty with respect to any tax consequences to ABE, Merger Sub, IRF or any IRF members arising under this Agreement or the transactions contemplated hereby and IRF hereby represents that its members are relying on independent advice regarding the tax consequences to them of such transactions.

Section 7.10           Indiana Plant Financing. The parties contemplate that an additional equity financing by ABE or Surviving Company will need to be completed in order to provide sufficient funds necessary to fund construction of a 100 million gallon per year ethanol plant to be located near Rochester, Indiana (the “Indiana Plant”). The terms and conditions of this financing, including but not limited to the total amount raised and the per unit price (if Surviving Company units are sold in the offering), will be determined by ABE’s board of directors in good faith and in compliance with their fiduciary duties, and will take into account the value of Surviving Company and its planned ethanol facility. In connection with this determination, ABE’s board of directors will obtain in advance and consider the input of Surviving Company’s board of directors. In addition, Former IRF Unitholders agree to cooperate and assist ABE, without additional consideration, in meeting with potential investors in the State of Indiana. ABE agrees that it will not develop an ethanol plant in the State of Indiana other than the Indiana Plant without the consent of Surviving Company’s board of directors until the financing described in this section is completed.

If after such applicable 30 day period there remains a dispute as to any claims, the Securityholders’ Representative and ABE shall attempt in good faith for 30 days to agree upon the rights of the respective parties with respect to each of such claims. If the Securityholders’ Representative and ABE should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and, if the claim was made in any Officer’s Certificate, such memorandum shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and shall distribute ABE Units from the Escrow Fund in accordance with the terms of the memorandum.

(b)           If no such agreement can be reached after good faith negotiation, either ABE or the Securityholders’ Representative may, by written notice to the other, demand arbitration of the matter unless the amount of the damage or loss is at issue in pending litigation with a third party, in which event

35

arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators. Within 15 days after such written notice is sent, ABE (on the one hand) and the Securityholders’ Representatives (on the other hand) shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator. The decision of the arbitrators as to the validity and amount of any claim in such Officer’s Certificate or Representative Certificate, as applicable, shall be binding and conclusive upon the parties to this Agreement, and notwithstanding anything in Section 10.5, the Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments out of the Escrow Fund in accordance with such decision.

Such agency may be changed by the holders of a majority in interest of the Escrow Fund from time to time upon not less than ten days’ prior written notice to ABE. No bond shall be required of the Securityholders’ Representative, and the Securityholders’ Representative shall receive no compensation for services. Notices or communications to or from the Securityholders’ Representative shall constitute notice to or from each of the Former IRF Unitholders.

(b)           The Securityholders’ Representatives shall not be liable for any act done or omitted hereunder as Securityholders’ Representative while acting in good faith, and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of such good faith. The Former IRF Unitholders shall severally and pro rata, in accordance with their respective Pro Rata Shares, indemnify the Securityholders’ Representative and hold him harmless against any loss, liability or expense incurred without gross negligence or bad faith on the part of the Securityholders’ Representative and arising out of or in connection with the acceptance or administration of his duties hereunder under this Agreement or the Escrow Agreement.

(c)           The Securityholders’ Representative shall have reasonable access to information about IRF and ABE and the reasonable assistance of IRF’s and ABE’s officers and employees for purposes of performing his duties and exercising his rights under this Article X, provided, that the Securityholders’ Representative shall treat confidentially and not disclose any nonpublic information from or about IRF or ABE to anyone (except on a need to know basis to individuals who agree to treat such information confidentially).

Section 10.9           Actions of the Securityholders’ Representative. A decision, act, consent or instruction of the Securityholders’ Representative shall constitute a decision of all of the Former IRF Unitholders and shall be final, binding and conclusive upon each such Former IRF Unitholder, and the Escrow Agent and ABE may rely upon any decision, act, consent or instruction of the Securityholders’ Representative as being the decision, act, consent or instruction of each and every such Former IRF

36

Unitholder. The Escrow Agent and ABE are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Securityholders’ Representative.

Section 10.10         Defense of Third-Party Claims. ABE shall determine and conduct the defense or settlement of any claim, demand, action, arbitration, investigation, inquiry or proceeding brought by a third party against ABE or such other ABE Indemnified Person (in each case, a “Third-Party Claim”) that is based on, arises out of or relates to any matter specified in Section 10.1, and the costs and expenses incurred by ABE in connection with such defense or settlement (including reasonable attorneys’ fees, other professionals’ and experts’ fees and court or arbitration costs) shall be included in the Damages for which ABE may seek indemnification pursuant to a claim made by any ABE Indemnified Person hereunder. The Securityholders’ Representative shall have the right to receive copies of all pleadings, notices and communications with respect to the Third-Party Claim to the extent that receipt of such documents by the Securityholders’ Representative does not affect any privilege relating to the ABE Indemnified Person and may participate in, but not determine or conduct, any defense of the Third-Party Claim or settlement negotiations with respect to the Third-Party Claim. No settlement of any such Third-Party Claim with any third party claimant shall be determinative of the existence of or amount of Damages relating to such matter, except with the consent of the Securityholders’ Representative, which consent shall not be unreasonably withheld, conditioned or delayed and which shall be deemed to have been given unless the Securityholders’ Representative shall have objected within ten days after a written request for such consent by ABE.

4.2           No Conflict. Neither the execution of this Agreement by ABE nor the consummation of the transactions contemplated hereby will result in a breach or violation of the terms of any agreement by which ABE is bound or by any decree, judgment, order, law or regulation now in effect of any court or other governmental body applicable to ABE.

NOW, THEREFORE, the parties, intending to be legally bound, hereby agree as follows:

1.             Acknowledgments by Unitholder. Unitholder acknowledges and understands that the representations, warranties and covenants by Unitholder set forth herein shall be relied upon by ABE, and its affiliates and counsel, and that substantial losses and damages may be incurred by such persons if Unitholder’s representations, warranties or covenants herein are breached or are incorrect or untrue. Unitholder has carefully read this Agreement and the Merger Agreement and has had an opportunity to discuss the requirements of this Agreement and the Merger Agreement with Unitholder’s professional advisors to the extent Unitholder has deemed necessary.

2.             Unitholder’s Representations.  Unitholder represents, warrants and covenants to ABE that:

(a)           Ownership of Membership Units of IRF.  Unitholder (together with such Unitholder’s spouse, if applicable) is the sole beneficial and record owner and holder of the membership units of IRF (“IRF Units”) set forth on the signature page hereof, which at the date hereof and at all times up until the Closing Date, will be free and clear of any liens, claims, options, charges, security interests, equities, options, warrants, rights to purchase (including, without limitation, restrictions on rights of disposition other than those imposed by applicable securities laws), third party rights of any nature or other encumbrance.

(b)           Authority; Due Execution.  Unitholder has full power and authority to make, enter into and carry out the terms of this Agreement.  Unitholder has duly executed and delivered this Agreement and (assuming the due authorization, execution and delivery of this Agreement by ABE) this Agreement shall constitute a valid and binding obligation of Unitholder, enforceable against Unitholder in accordance with its terms.

(c)           Information Concerning ABE.  Unitholder has had the opportunity to ask questions of, and obtain any additional information reasonably available to, ABE and IRF with respect to

1

their respective plans, results of operations, financial conditions, businesses, properties, assets or business prospects, and Unitholder has received all such information as Unitholder deems necessary and appropriate to enable Unitholder to evaluate the risks and merits of the Merger and the ABE Units to be received in connection therewith.  Unitholder acknowledges that the ABE Units are not registered under the Securities Act of 1933, as amended (the “Securities Act”) or the Securities and Exchange Act of 1934, as amended.  Unitholder understands that no public market now exists for any of the securities issued by ABE and that ABE has made no assurances that a public market will ever exist for its securities.

(d)           Economic Risk.  Unitholder can look after Unitholder’s financial interests in connection with the Merger, has such knowledge and experience in financial or business matters as to be able to evaluate the merits and risks of the Merger, and is able to suffer a complete loss on Unitholder’s investment in the ABE Units.

(e)           Residency.  Unitholder is a bona fide resident of the state set forth under Unitholder’s signature and the ABE Units are to be delivered to the Unitholder in that state.

(f)            Accredited Investor Status.  Unitholder is an “accredited investor” within the meaning of Rule 501 under the Securities Act, coming within the category or categories marked on the signature page to this Agreement, unless otherwise marked.  For any category marked, the Unitholder has truthfully set forth the factual basis or reason the undersigned comes within that category. The Unitholder agrees to furnish any additional information that ▇▇▇ ▇▇▇▇▇ necessary in order to verify the answers set forth below.

(g)           Entity Status.  If Unitholder is not an individual, (a) Unitholder was not organized for the specific purpose of acquiring the ABE Units.

(h)           Indemnification.  Unitholder agrees to indemnify and hold ABE harmless from any liability, loss or expense (including reasonable attorneys’ fees) if the Unitholder, alone or with others, defaults in any of the representations, warranties or covenants set forth in this Agreement.

3.             Restrictions on and Procedure for Sales.

(a)           Restrictions on Transfer of ABE Units.  Unitholder agrees that, notwithstanding the fact that the ABE Units issued in the Merger will be issued pursuant to an exemption from the registration requirements under the Securities Act pursuant to Section 4(2) of the Securities Act and Rule 506 of Regulation D promulgated thereunder, Unitholder will not make any sale, transfer, or other disposition of such ABE Units received by Unitholder in the Merger unless: (i) such sale, transfer or other disposition is within the applicable limitations of and in compliance with Rule 144 (“Rule 144”) promulgated by the Securities and Exchange Commission under the Securities Act in the opinion of counsel reasonably acceptable to ABE, or (ii) some other exemption from registration under the Securities Act and any applicable state securities law is available with respect to any such proposed sale, transfer or other disposition of such ABE Units in the opinion of counsel reasonably acceptable to ABE, or (iii) such sale, transfer or other disposition of ABE Units has been registered under the Securities Act.  Unitholder has no present intention to sell or otherwise dispose of such ABE Units and is acquiring such ABE Units for investment and not with a view to resale or distribution.  Unitholder is familiar with the provisions of, and restrictions imposed by, Rule 144 and understands that any sale, transfer or disposition under Rule 144 is conditioned upon various requirements which may include the time and manner of sale, the holding period of the securities and requirements relating to ABE which are outside of Unitholder’s control and which ABE is under no obligation and may not be able to satisfy.  Unitholder further understands that ABE has no obligation to register or qualify the ABE Units for resale.

2

(b)           Legend.  Unitholder understands that all certificates representing ABE Units deliverable to Unitholder pursuant to the Merger Agreement shall, until the occurrence of one of the events enumerated in Section 3(a) above, bear a legend substantially as follows:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED EXCEPT (i) PURSUANT TO REGISTRATION UNDER APPLICABLE FEDERAL AND STATE SECURITIES LAWS OR APPLICABLE EXEMPTIONS THEREFROM OR (ii) IF, IN THE OPINION OF COUNSEL REASONABLY ACCEPTABLE TO ADVANCED BIOENERGY, LLC, THE PROPOSED TRANSFER MAY BE EFFECTED IN COMPLIANCE WITH APPLICABLE FEDERAL AND STATE SECURITIES LAWS WITHOUT REGISTRATION.

THIS SECURITY MAY NOT BE SOLD, EXCHANGED OR OTHERWISE TRANSFERRED OR DISPOSED OF EXCEPT IN COMPLIANCE WITH THE TERMS AND PROVISIONS OF THE UNITHOLDER AGREEMENT DATED AS OF                    , 2006 BETWEEN ADVANCED BIOENERGY, LLC AND THE RECORD OWNER OF THIS SECURITY, AS IT MAY BE AMENDED, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF ADVANCED BIOENERGY, LLC.

(c)           Transferees Subject to Restrictions.  Any transferee of ABE Units from Unitholder shall be subject to the restrictions set forth in Section 3(a) above, and Unitholder shall condition such transfer on the transferee’s agreement in writing to be so bound.

4.             Limitations on Transfer.  In addition to any other limitation on transfer created by applicable securities laws or this Agreement, Unitholder shall not assign, encumber or dispose of any interest in ABE Units received by Unitholder except in compliance with applicable securities laws.  All transferees of ABE Units or any interest therein will receive and hold such ABE Units or interest subject to the provisions of this Agreement.  Any sale or transfer of the ABE Units shall be void unless the provisions of this Agreement are satisfied.

5.             Additional Agreements, Covenants and Representations Related to the Merger.

(a)           Unitholder agrees to not sell or otherwise transfer or dispose of the ABE Units (or any other ABE securities) held by the Unitholder during the 90-day period after the effective date of an ABE registration statement filed under the Securities Act, provided that all ABE officers and directors are bound by and have entered into similar agreements.  The obligations described in this Section 5(d) will not apply to a registration relating solely to employee benefit plans on Form S-l or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future.  ABE may impose stop-transfer instructions with respect to the ABE Units (or any other ABE securities) subject to the foregoing restriction until the end of such 90-day period.  Unitholder agrees to execute a lock-up agreement with any underwriters in customary form consistent with the provisions of this Section.

6.             Miscellaneous.

(a)           This Agreement constitutes the entire agreement between the parties pertaining to the subject matter hereof.  No waiver of any of the provisions of this Agreement shall be deemed, or shall constitute, a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing waiver.  No waiver shall be binding unless executed in writing by the party making the waiver.

(b)           For the convenience of the parties hereto, this Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same document.

(c)           This Agreement shall be enforceable by, and shall inure to the benefit of and be binding upon, the parties hereto and their respective successors and assigns.  As used herein, the term “successors and assigns” shall mean, where the context so permits, heirs, executors, administrators, trustees and successor trustees, and personal and other representatives.

(d)           All notices, requests, consents and other communications required or permitted hereunder will be in writing and will be delivered, or sent by facsimile transmission, or mailed first-class postage prepaid, registered or certified mail, as follows:

(g)           Unitholder acknowledges that this Agreement is one of a number of substantially identical agreements being entered into between ABE and holders of IRF Units.  Unitholder agrees that any term of this Agreement may be amended upon the written consent of ABE and the holders of a majority of the then-outstanding ABE Units into which IRF Units were exchanged in connection with the Merger, and such amendment shall be binding on Unitholder and its permitted successors and assigns.

ESCROW AGREEMENT

This ESCROW AGREEMENT (this “Agreement”) is entered into as of May *[    ], 2006, by and among Advanced BioEnergy, LLC, a Delaware limited liability company (“ABE”), ▇▇▇▇▇ Fargo Bank, National Association, as Escrow Agent (“Escrow Agent”) and ▇▇▇▇ ▇▇▇▇, as Securityholders’ Representative (“Securityholders’ Representative”) of the Former IRF Unitholders.

RECITALS

A.            ABE, Indiana Renewable Fuels, LLC, an Indiana limited liability company (“IRF”), and IRF Acquisition, LLC, an Indiana limited liability company and wholly owned subsidiary of ABE (“Merger Sub”), have entered into an Agreement and Plan of Merger (the “Merger Agreement”), which provides for the merger (the “Merger”) of Merger Sub with and into IRF.  Terms used herein and not defined herein have the meanings set forth in the Merger Agreement.

B.            Section 2.2 of the Merger Agreement provides that at the Effective Time, ABE will withhold *[75,000] of the ABE Units issuable to the Former IRF Unitholders (the “Escrow Amount”).  Section 10.3(a) of the Merger Agreement provides that, as soon as practicable after the Effective Time, a certificate representing the Escrow Amount shall be deposited with the Escrow Agent (such deposit to constitute the “Escrow Fund”).  The Escrow Amount shall be held in accordance with each Former IRF Unitholder’s Pro Rata Share.  The aggregate Escrow Amount of all Former IRF Unitholders is hereinafter collectively referred to as the “Initial Escrow Property” and, together with the Additional Escrow Units, the “Escrow Property.”

C.            The parties to this Agreement desire to establish the terms and conditions pursuant to which the Escrow Amounts will be deposited, held in, and disbursed from the Escrow Fund.

NOW, THEREFORE, the parties, intending to be legally bound, agree as follows:

1.             Escrow Fund.  The Escrow Agent agrees to: (a) accept delivery of the Escrow Amount; and (b) hold such Escrow Amount in escrow as part of the Escrow Fund, all subject to the terms and conditions of this Agreement and Article X of the Merger Agreement (which Article X is attached to this Agreement as Appendix I and incorporated by reference into this Agreement) (collectively, the “Escrow Provisions”).

2.             Deposit of Escrow Amounts: Release from Escrow.

(a)           Delivery of Escrow Amounts.  As soon as practicable after the Effective Time, the Escrow Amount will be deposited by ABE on behalf of the Former IRF Unitholders with the Escrow Agent.  Any ABE Units comprising a portion of the Escrow Amount (the “Escrow Units”) will be issued in the name of the Escrow Agent.  In the event that ABE issues additional ABE Units constituting additional escrow property (the “Additional Escrow Units”), such units shall be issued in the name of the Escrow Agent and delivered to the Escrow Agent in the same manner as the Escrow Units.

(b)           Former IRF Unitholders’ Accounts.  The Escrow Agent will maintain for each Former IRF Unitholder an accounting record (each Former IRF Unitholder’s “Account”) specifying the portion of the Escrow Amount held for the record of each Former IRF Unitholder pursuant to the Escrow Provisions. All Escrow Amounts received under Section 2(a) will be allocated to each Former IRF Unitholder’s Account in accordance with such Former IRF Unitholder’s Pro Rata Share in the Escrow Fund as set forth on Appendix II.

(c)           Dividends, Voting and Rights of Ownership.  Except for tax-free dividends paid in equity securities declared with respect to the Escrow Units (the “Additional Escrow Securities”) pursuant to Section 305(a) of the Internal Revenue Code of 1986, as amended (the “Code”), there will be distributed promptly to the Former IRF Unitholders any cash dividends or dividends payable in securities

1

or other distributions of any kind made in respect of the Escrow Units.  Additional Escrow Units, if any, will be credited to each Former IRF Unitholder’s Account in accordance with each Former IRF Unitholder’s Pro Rata Share.  Each Former IRF Unitholder will have voting rights with respect to the Escrow Units deposited in the Escrow Fund with respect to such Former IRF Unitholder so long as such Escrow Units are held in the Escrow Fund.  While the Escrow Units remain in the Escrow Agent’s possession pursuant to this Agreement and the Merger Agreement, the Former IRF Unitholders will be able to exercise all other incidents of ownership of said Escrow Units that are not inconsistent with the terms and conditions of this Agreement and the Merger Agreement.  Any funds received under this section will not be invested by the Escrow Agent.

(d)           ABE Unit Dividends and Splits or Conversion.  In the event of any unit dividend, unit split or similar recapitalization with respect to the ABE Units that becomes effective while the Escrow Units are held in the Escrow Fund, or upon any optional conversion (at the election of the respective Former IRF Unitholders as to his number of Escrow Units then held in the Escrow Fund) or mandatory conversion of such units, the additional securities of ABE issued in respect of the Escrow Units shall be added to the Escrow Fund and shall be subject to the terms and conditions of this Agreement as if such units were initially delivered.  In the event of such a conversion, all references to Escrow Units as used herein shall be deemed to refer to the underlying equity interests of ABE issued upon such conversion.

(e)           Release.  The Escrow Property will be held by the Escrow Agent until required to be released to the Former IRF Unitholders pursuant to Section 10.4 of the Merger Agreement, unless previously delivered to ABE pursuant to Section 10.5 of the Merger Agreement.  Within five business days following the date that the applicable release condition is met, ABE and the Securityholders’ Representative will deliver written instructions to the Escrow Agent setting for the number of ABE Units to be delivered to each Former IRF Unitholder (the “Release Instructions”).  As soon as reasonably practicable after receipt of Release Instructions, the Escrow Agent will deliver to the Securityholders’ Representative the portion of the Escrow Property to be released.  Escrow Property will be delivered to the Securityholders’ Representative in the form of a unit certificate(s) issued in the name of each such Former IRF Unitholder.  The Escrow Property will be released to the respective Former IRF Unitholders by the Securityholders’ Representative in accordance with their respective Accounts.  Escrow Agent and ABE will take such action as may be necessary to cause such unit certificate(s) to be issued in the names of the appropriate Former IRF Unitholders.  Cash will be paid in lieu of fractional units in an amount equal to the product determined by multiplying such fraction by $10.00 as set forth in such Release Instructions.

(g)           No Encumbrance.  No Escrow Property or any beneficial interest in the Escrow Property may be pledged, sold, assigned or transferred, including by operation of law, by a Former IRF Unitholder or be taken or reached by any legal or equitable process in satisfaction of any debt or other liability of a Former IRF Unitholder, prior to the delivery to such Former IRF Unitholder of such Former IRF Unitholder’s portion of the Escrow Property by the Escrow Agent.

(h)           Power to Transfer Escrow Securities.  The Escrow Agent is granted the power to effect any transfer of the Escrow Units contemplated by the Escrow Provisions.  ABE will cooperate with the Escrow Agent in promptly (but in any event, for so long as ABE is the transfer agent for the ABE Units, no later than ten days after being instructed to do so by the Escrow Agent) issuing unit certificates to effect such transfers.

(h)           Tax Reporting.  The parties hereto agree that the Former IRF Unitholders shall be treated for all tax purposes as the owners of their Pro Rata Share of the Escrow Property as indicated on Appendix II hereto.  Within 30 days of the date hereof, the Securityholders’ Representative shall furnish to the Escrow Agent Internal Revenue Service (“IRS”) Forms W-9 or Forms W-8BEN for the

2

Former IRF Unitholders.  The parties agree that any interest and other earnings attributable to the Escrow Property shall be treated for U.S. tax purposes as income of the Former IRF Unitholders in the respective proportions indicated on Appendix II hereto.  Should any issue arise regarding federal income tax reporting or withholding, the Escrow Agent shall act in accordance with the written instructions of the Securityholders’ Representative and ABE.

3.             Limitation of the Escrow Agent’s Liability.

(a)           The Escrow Agent will incur no liability with respect to any action taken or suffered by it in reliance upon any notice, direction, instruction, consent, statement or other document believed by it to be genuine and duly authorized, nor for any other action or inaction, except its own willful misconduct, bad faith or gross negligence.  Concurrent with the execution of this Escrow Agreement, ABE and Securityholders’ Representative, respectively, shall deliver to the Escrow Agent an authorized signers form in the form of Exhibit A-1 and Exhibit A-2 to this Escrow Agreement The Escrow Agent will not be responsible for the validity or sufficiency of the Escrow Provisions.  In all questions arising under the Escrow Provisions, the Escrow Agent may rely on the advice of counsel, and for anything done, omitted or suffered in good faith by the Escrow Agent based on such advice, the Escrow Agent will not be liable to anyone.  The Escrow Agent will not be required to take any action under the Escrow Provisions involving any expense unless the payment of such expense is made or provided for in a manner satisfactory to it.  In no event shall the Escrow Agent be liable, directly or indirectly, for any (i) damages or expenses arising out of the services provided hereunder, other than damages which result from the Escrow Agent’s gross negligence or willful misconduct, or (ii) special or consequential damages, even if the Escrow Agent has been advised of the possibility of such damages.

(b)           In the event conflicting demands are made or notices are served upon the Escrow Agent with respect to the Escrow Fund, the Escrow Agent will have the absolute right, at the Escrow Agent’s election, to do either or both of the following:  resign so a successor can be appointed pursuant to Section 5 or file a suit in interpleader and obtain an order from a court of competent jurisdiction requiring the parties to interplead and litigate in such court their several claims and rights among themselves.  In the event such interpleader suit is brought, the Escrow Agent will thereby be fully released and discharged from all further obligations imposed upon it under the Escrow Provisions, and ABE will pay the Escrow Agent (and ABE may be reimbursed by the Former IRF Unitholders pursuant to Section 4) all costs, expenses and reasonable attorney’s fees expended or incurred by the Escrow Agent pursuant to the exercise of the Escrow Agent’s rights under this Section 3 (such costs, fees and expenses will be treated as extraordinary fees and expenses for the purposes of Section 4).

(c)           ABE and the Former IRF Unitholders and their successors and assigns agree jointly and severally to indemnify and hold Escrow Agent harmless against any and all losses, claims, damages, liabilities, and expenses, including reasonable costs of investigation, counsel fees, including allocated costs of in-house counsel and disbursements that may be imposed on Escrow Agent or incurred by Escrow Agent in connection with the performance of its duties under this Agreement, including but not limited to any litigation arising from this Agreement or involving its subject matter.  The indemnification provided by this section shall survive the resignation or removal of the Escrow Agent and the termination of this Agreement.

(d)           Notwithstanding anything in this Section 3, no indemnity need be paid in the event of the Escrow Agent’s gross negligence, bad faith or willful misconduct.

4.             Expenses.

before the closing shall be paid at the Effective Time.  Any additional fees and expenses, including without limitation any fees or expenses incurred by the Escrow Agent in connection with a dispute over the distribution of Escrow Property or the validity of a claim or claims by ABE, will be paid divided evenly between ABE and the Former IRF Unitholders.  The Former IRF Unitholders’ liability for the extraordinary fees and expenses of the Escrow Agent may be paid by ABE and recovered as a claim hereunder out of the Escrow Fund.  If ABE has paid the Former IRF Unitholders’ portion of such fees and expenses as permitted under this Section 4(a) then the Escrow Agent will, upon demand by ABE, transfer to ABE a portion of the Escrow Property, equal to such portion of fees and expenses.

(b)           Securityholders’ Representative.  The Securityholders’ Representative will not be entitled to receive any compensation from ABE or the Former IRF Unitholders in connection with this Agreement.  Except as set forth in the Merger Agreement, any loss, liability or expense incurred by the Securityholders’ Representative in connection with actions taken pursuant to the terms of the Escrow Provisions will be paid by the Former IRF Unitholders.

5.             Successor Escrow Agent.  In the event the Escrow Agent becomes unavailable or unwilling to continue in its capacity as such, the Escrow Agent may resign and be discharged from its duties or obligations hereunder by giving written notice to the parties to this Agreement, specifying not less than thirty days’ prior notice of the date when such resignation will take effect.  ABE will designate a successor Escrow Agent (with the consent of the Securityholders’ Representative, which will not be unreasonably withheld) prior to the expiration of such 30-day period by giving written notice to the Escrow Agent and the Securityholders’ Representative.  ABE may appoint a successor Escrow Agent with the consent of the Securityholders’ Representative, which will not be unreasonably withheld.  The Escrow Agent will promptly transfer the Escrow Property to such designated successor.  In the event no successor Escrow Agent is appointed as described in this Section 5, the Escrow Agent may apply to a court of competent jurisdiction for the appointment of a successor Escrow Agent.

Section 10.5           Claims for Damages.

(a)           Upon receipt by the Escrow Agent on or before the last day of the Escrow Period of a certificate signed by any appropriately authorized officer of ABE (an “Officer’s Certificate”):

Section 10.7           Resolution of Conflicts.

(a)           If the Securityholders’ Representatives shall object in writing to any claim or claims by ABE made in any Officer’s Certificate, then ABE shall have 30 days to respond in a written statement to the objection of the Securityholders’ Representatives.  If ABE shall object in writing to any claim or claims on behalf of the Securityholder Indemnified Parties made in any Representative Certificate, then the Securityholders’ Representative shall have 30 days to respond in a written statement to the objection of ABE.  If after such applicable 30 day period there remains a dispute as to any claims, the Securityholders’ Representative and ABE shall attempt in good faith for 30 days to agree upon the rights of the respective parties with respect to each of such claims.  If the Securityholders’ Representative and ABE should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and, if the claim was made in any Officer’s Certificate, such memorandum shall be furnished to the Escrow Agent.  The Escrow Agent shall be entitled to rely on any such memorandum and shall distribute ABE Units from the Escrow Fund in accordance with the terms of the memorandum.

(b)           If no such agreement can be reached after good faith negotiation, either ABE or the Securityholders’ Representative may, by written notice to the other, demand arbitration of the matter unless the amount of the damage or loss is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators.  Within 15 days after such written notice is sent, ABE (on the one hand) and the Securityholders’ Representatives (on the other hand) shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator.  The decision of the arbitrators as to the validity and amount of any claim in such Officer’s Certificate or Representative Certificate, as applicable, shall be binding and

I-3

conclusive upon the parties to this Agreement, and notwithstanding anything in Section 10.5, the Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments out of the Escrow Fund in accordance with such decision.

(c)           Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction.  Any such arbitration shall be held in Minneapolis, Minnesota under the commercial rules then in effect of the American Arbitration Association.
