NOW, THEREFORE, in consideration of such employment and the mutual covenants and promises herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company, Holdings and the Executive agree as follows:

Section 1.               Employment and Position.  Subject to Section 2, the Company hereby agrees to continue to employ the Executive as its Chief Executive Officer, and the Executive hereby agrees to continue such employment under and subject to the terms and conditions hereinafter set forth.  From and after the date that the equity securities of Holdings are converted to common stock of IPO Corp. in accordance with Section 3.6 of the Securityholders Agreement (the “Conversion”), all references to Company in this Agreement shall mean IPO Corp.  In no

event will the substitution of IPO Corp. as the Company under this Agreement constitute a termination of employment under this Agreement.

Section 2.               Term.  The term of employment under this Agreement shall begin on the date hereof and, unless sooner terminated as provided in Section 6, shall conclude on the three year anniversary of the date hereof (the “Term”).  The Term shall automatically renew for an additional one year period at the end of the initial Term and each successive year thereafter unless either party provides the other with written notice of termination at least 30 days’ prior to the end of such initial Term or successive one year term thereafter.

Section 3.               Duties.  The Executive shall perform services in a managerial capacity in a manner consistent with the Executive’s position as Chief Executive Officer, subject to the general supervision of the Board of Directors of the Company (the “Board”) and the terms of the Amended and Restated Limited Liability Company Agreement dated the date hereof, among the Executive, Holdings, the Seller, the Investors and the other parties thereto (the “LLC Agreement”), the Limited Liability Company Securityholders Agreement dated the date hereof, among the Executive, Holdings, the Seller, the Investors and the other parties thereto (the “Securityholders Agreement”) and, after the date of the Conversion, the by-laws of IPO Corp.; provided, however, that no amendment or modification of the LLC Agreement, the Securityholders Agreement or the by-laws of IPO Corp. after the date hereof which would have the effect of altering any of the terms of this Agreement shall be effective without the consent of the Executive.  The Executive hereby agrees to devote his full business time and best efforts to the faithful performance of such duties and to the promotion and forwarding of the business and affairs of the Company for the Term.

Section 4.               Compensation; Equity Participation.

Section 4.01           Compensation.  (a) Salary.  In consideration of the services rendered by the Executive under this Agreement, the Company shall pay the Executive a base salary at the rate of $250,000 per calendar year (the “Base Salary”).  The Base Salary shall be paid in such installments and at such times as the Company pays its regularly salaried executives and shall be subject to all necessary withholding taxes, FICA contributions and similar deductions.  The Board will review annually the Base Salary payable to Executive hereunder and may, in its sole discretion, increase but not decrease, the Executive’s rate of compensation.  Any such increased Base Salary shall be and become the “Base Salary” for purposes of this Agreement.

                (b)           Annual Bonus.  During the Term, the Executive shall be eligible to receive an annual bonus in an amount up to two hundred percent (200%) of the Base Salary (the “Annual Bonus”).  The Annual Bonus shall be calculated and payable in accordance with and based on operating performance targets established by the Board by reference to the budget approved from time to time by the Board for such fiscal year (the “Annual Budget”).  The Annual Bonus will be calculated and payable in accordance with formula to be agreed to by the Company and the Executive after the date hereof.  The parties each will use their commercially reasonable efforts (including taking the actions described in Section 13.01 hereof) to structure and pay such Annual Bonus so as to comply with the requirements of Internal Revenue Code Section 409A in order to ensure that any amounts paid or payable as an Annual Bonus are not subject to the additional 20% income tax.  The Annual Bonus shall be paid within thirty (30) days after receipt of audited

2

financial statements by the Company for the applicable fiscal year.  For purposes of determining any Annual Bonus for 2006 (assuming projected bonuses for 2006 have been accrued on the Company’s monthly balance sheets for each month preceding the closing of the Transaction), the Executive shall be deemed to have commenced employment hereunder as of the first day of such fiscal year.  Any compensation paid to the Executive as the Annual Bonus shall be in addition to the Base Salary.  Annual Bonus performance criteria are subject to annual review and change by the Board relative to key strategic objectives for the year; provided that, the Executive’s Annual Bonus opportunity provided for hereunder (i.e., the percentage of Base Salary) may not be modified without the Executive’s prior written consent.  Upon calculation of the Annual Bonus, the Board shall be provided with a summary of the Executive’s compensation and other payments received by the Executive from the Company for the preceding fiscal year, including but not limited to, Base Salary, Annual Bonus, expenses, and related party transactions.

Section 4.02:  Profits Interest.   The Executive shall be granted on the date hereof one million eighty-three thousand three-hundred and thirty three (1,083,333) Class B common units in Holdings representing 2.499% of the outstanding common equity interests of Holdings on the date hereof (the “Employee Units”).  The Employee Units shall participate in distribution of Holdings and shall be subject to vesting and the other terms contained in (i) the LLC Agreement, and (ii) that certain Restricted Unit Agreement of even date between the Executive and Holdings (“Restricted Unit Agreement”), which is incorporated herein by reference.

Section 5.   Benefits.  In addition to the compensation detailed in Section 4 of this Agreement, the Executive shall be entitled to the following additional benefits:

Section 5.02.          Insurance Coverage.  During the Term, the Executive and the Executive’s family shall be eligible for participation in and shall receive benefits under welfare benefit plans, practices, policies and programs provided by the Company which provide benefits and coverage levels which are at least equal to the benefits and coverage levels made available to executives of the Company immediately prior to the date hereof.  The Company may, at its election and for its benefit, insure the Executive against disability, accidental loss or death and the Executive shall submit to such physical examinations and supply such information as may be required in connection therewith.

Section 5.03.          Reimbursement of Expenses.  The Company shall reimburse the Executive for all reasonable and necessary expenses actually incurred by the Executive directly in connection with the business affairs of the Company and the performance of his duties hereunder upon presentation of proper receipts or other proof of expenditure and subject to such guidelines established by the Company from time to time.  The Executive shall comply with such guidelines and reporting requirements with respect to such expenses as the Board may establish from time to time.

Section 5.04.          Other Benefit Plans.  During the Term, the Executive shall be entitled to participate in all incentive, savings, retirement and pension plans, practices, policies and programs applicable generally to other executives of the Company, including but not limited to, an equity incentive plan maintained by the Company; provided, however, that if the Company does not provide retirement or pension plans after the date of the Conversion, the Executive shall be entitled to participate in any such plans that may, in the Company’s discretion, be maintained by Hawkeye Renewables, LLC.

Section 6.03.          By the Company For Cause.  The employment of the Executive may be terminated by the Company for Cause (as defined below) at any time effective upon written notice to the Executive.  For purposes hereof, the term “Cause” shall mean:

(b)           engaging in conduct that is demonstrably and materially injurious to the business, reputation, character, or community standing of the Company;

(c)           continued material failure to perform the duties described in Section 3 for 15 days after written notice from the Company to the Employee providing a detailed description of the failure constituting cause;

Section 6.04.          By the Company without Cause.  The Company may terminate the Executive’s employment at any time without Cause effective upon 60 days prior written notice to

4

the Executive, provided that, in lieu of such prior written notice, the Company may continue to pay the Executive’s compensation and provide the benefits contemplated hereunder for such 60-day period and for purposes of Section 7.02 the Executive’s termination date shall be considered to be the end of such 60-day period.  Expiration or termination of the Term as provided for in Section 2 shall not constitute termination without Cause.

Section 6.06.          By the Executive for Good Reason.  The Executive may terminate this Agreement effective upon written notice to the Company for Good Reason.  Such notice must provide a detailed explanation of the Good Reason.  Any such termination shall be treated for purposes of this Agreement as a termination by the Company without Cause.  For this purpose, the term “Good Reason” shall mean:  (i) a material diminution in or assignment of duties inconsistent with Executive’s position prior to the date of this Agreement or a change in the Executive’s direct reporting relationship, provided, however, that a change in title shall not itself be considered a material diminution; (ii)  a reduction in Base Salary or a reduction in Annual Bonus (it being understood that the failure to receive an Annual Bonus or a reduced Annual Bonus due to failure to meet applicable performance targets shall not be considered a reduction in Annual Bonus hereunder); or (iii) any breach of this Agreement by Company, provided, the Company is provided written notice of such breach by Executive and is provided 15 days to cure such breach; or (iv) any material breach of the Securityholders’ Agreement or LLC Agreement by the Company which has an adverse impact upon Executive and which is not cured within 15 days after written notice of such breach is provided by Executive to the Company.
