Borrower has (i) commenced construction of the Project and will cause the construction of the Project to be prosecuted with diligence and continuity in accordance with the Schedule of Construction for the Project, and will fully complete the same in substantial accordance with the Project Plans and Specifications free and clear of liens or claims for liens for material supplied and for labor or services performed in connection with the construction of the Project, on or before the Project Completion Date, and except that such date may be extended for Unavoidable Delays, provided, that Borrower shall have the right to contest any such lien claim in good faith so long as Borrower escrows an amount equal to one hundred twenty-five percent (125%) of the amount of such claim with Lender, or by obtaining a bond over the same in an amount and from a bonding company reasonably acceptable to Lender, and (ii) commenced construction of the Project Addition and will cause the construction of the Project Addition to be prosecuted with diligence and continuity in accordance with the Schedule of Construction for the Project Addition, and will complete the same in substantial accordance with the Project Addition Plans and Specifications free and clear of liens or claims for liens for material supplied and for labor or services performed in connection with the construction of the Project Addition, on or before the Project Addition Completion Date, and except that such date may be extended for Unavoidable Delays.

7.9 Restrictive Covenants. Borrower will comply with all restrictive covenants affecting the Property and/or the Project.

7.10 Insurance.

(a) Borrower at its sole cost and expense shall provide or cause to be provided and shall keep in force at all times for the benefit of Lender, with respect to the Property and the Improvements the following insurance coverages:

(i) builder’s all-risk completed value, non-reporting form insurance to cover all development and/or construction work, buildings, improvements and off-site and on-site materials on properties covered by the Leasehold Mortgage and this Agreement in an amount equal to the full insurable value of the Improvements;

(ii) insurance against loss of or damage to the Improvements by fire and other hazards covered by so-called “extended coverage” and such other casualties and hazards as Lender shall require from time to time;

(iii) insurance against loss or damage by earthquake in a commercially reasonable amount;

(iv) flood insurance in a commercially reasonable amount if the Property is now or later becomes designated as located in a flood hazard area as described in the Flood Disaster Protection Act of 1973;

(v) comprehensive general public liability insurance against claims for bodily injury, death or property damage;

(vi) such other insurance on the Property and the Improvements or any replacements or substitutions thereof, as Lender may reasonably require.

The policies of insurance required by this paragraph shall be with companies having at least an A- Class VIII rating by BEST Insurance Reports, and shall be in forms, amounts, limits and coverages and for such periods and subject to such deductibles, as Lender shall require from time to time, and shall insure the respective interests of Borrower and Lender. Such insurance may not be provided in umbrella policies covering more than one property without the prior written consent of Lender. The insurance proceeds thereof (other than the proceeds from the policy required under clause (v) above) shall be payable to Lender pursuant to a non-contributing first mortgage endorsement satisfactory in form and substance to Lender. Original policies and renewals thereof (or satisfactory certificates of insurance) covering the risks provided by this Agreement to be insured against, bearing satisfactory evidence of payment of all premiums thereon, shall be delivered to and held by Lender. At least ten (10) days prior to the expiration of

each policy required to be provided by Borrower, Borrower shall deliver renewal policies or certificates to Lender with appropriate evidence of payment of premiums therefore. All insurance policies required by this Agreement shall:

(1) include effective waivers by the insurer of all rights of subrogation against any named insured, the indebtedness secured by the Leasehold Mortgage and the Property and all claims for insurance premiums against Lender;

(2) provide that any losses shall be payable to Lender notwithstanding (A) any act, failure to act or negligence of or violation of warranties, declarations or conditions contained in such policy by any named insured, (B) the occupation or use of the Premises for purposes more hazardous than permitted by the terms thereof, or (C) any foreclosure or other action or proceeding taken by Lender pursuant to any provision of this Agreement.

(3) provide that no cancellation or reduction in amount in coverage thereof shall be effective until at least twenty (20) days after receipt by Lender of written notice thereof; and

(4) be reasonably satisfactory in all other respects to Lender.

Borrower shall not permit any activity to occur or condition to exist on or with respect to the Property or the Improvements that would wholly or partially invalidate any of the insurance thereon. Borrower shall promptly notify Lender of any material change in coverage under any insurance policy of Borrower.

(b) Borrower irrevocably makes, constitutes and appoints Lender (and all officers, employees or agents designated by Lender) as Borrower’s true and lawful attorney-in-fact and agent, with full power of substitution, for the purpose of making and adjusting claims under such policies of insurance, endorsing the name of Borrower on any check, draft, instrument or other item of payment of the proceeds of such policies of insurance and for making all determinations and decisions with respect to such policies of insurance required above or to pay any premium in whole or in part relating thereto. Lender, without waiving or releasing any obligation or default by Borrower hereunder, may (but shall be under no obligation to do so) at any time or times hereafter maintain such action with respect thereto as Lender deems advisable. All sums disbursed by Lender in connection therewith, including reasonable attorneys’ fees, court costs, expenses and other charges relating thereto, shall be payable, on demand, by Borrower to Lender and shall be additional Obligations hereunder secured by the Leasehold Mortgage and each of the other Loan Documents which secure the Obligations. Lender agrees not to exercise the power of attorney granted in this subparagraph (b) until the occurrence of an Event of Default.

(c) All proceeds of the insurance required to be obtained by Borrower hereunder, other than those relating to the insurance required under clause (v) of subparagraph (a) hereof, shall be paid to Lender. Lender may deduct from such proceeds any expenses, including, without limitation, reasonable legal fees, incurred by it in connection with adjusting

and obtaining such proceeds (the balance remaining after such deduction being hereinafter referred to as the “Net Insurance Proceeds”), and thereafter Lender may, subject to subsection (d) immediately below, apply such proceeds toward the payment or performance of Borrower’s obligations evidenced by this Agreement, the Notes or any other Loan Documents, whether or not such obligations are then due, or release such proceeds to Borrower in accordance with the terms and conditions of the Leasehold Mortgage. So long as Borrower shall not be in default hereunder, Borrower shall have the right to participate with Lender in the adjustment and compromise of any claims, but the decision of Lender in any such case shall be binding and conclusive upon Borrower.

(d) In case of any loss covered by insurance or in case of any damage caused by a taking or exercise of eminent domain, notwithstanding anything in this Agreement to the contrary, provided that (i) no Event of Default then exists, (ii) the Construction/Term Loan Maturity Date does not fall within the six (6) month period following the date of the casualty or taking, (iii) in Lender’s good faith judgment the Improvements can be repaired or restored prior to the Construction/Term Loan Maturity Date, (iv) Lender reasonably determines the restoration of the Improvements is economically feasible, (v) Lender reasonably determines that the Borrower’s operation or financial condition will materially benefit from restoration of the collateral, (vi) Borrower is a viable operating entity at the time the loss occurred, and (vii) Borrower deposits with Lender the amount of deficiency, if any, between the estimated cost of (x) restoration or repair and completion of the Improvements (as determined by Lender in its good faith judgment) and (y) the amount of Net Insurance Proceeds plus the undisbursed proceeds of the Loan, then Lender shall make the Net Insurance Proceeds available to Borrower on the terms and conditions set forth in this Agreement for disbursement of the Loan, together with such additional terms and conditions as are customary and as may be reasonably required by Lender in the circumstances. The application of any insurance proceeds toward the payment or performance of the obligations shall not be deemed a waiver by Lender of its right to receive payment or performance of the rest of the obligations and the interest thereon in accordance with the provisions of this Agreement.

(e) To the extent permitted by such policies, in the event of a foreclosure under the Leasehold Mortgage, the purchaser of Borrower’s interest in the Property and the Improvements shall succeed to all of the rights of Borrower, including any right to unearned premiums, in and to all policies of insurance which Borrower is required to maintain under this paragraph and to all proceeds of such insurance.

(f) Pursuant to Mo. Rev. Stat. §427.120, Borrower acknowledges receipt of the following notice: “Unless you [Borrower] provide evidence of the insurance coverage required by your agreement with us [Lender], we may purchase insurance at your expense to protect our interests in your collateral. This insurance may, but need not, protect your interests. The coverage that we purchase may not pay any claim that you make or any claim that is made against you in connection with the collateral. You may later cancel any insurance purchased by us, but only after providing evidence that you have obtained insurance as required by our agreement. If we purchase insurance for the collateral, you will be responsible for the costs of that insurance, including the insurance premium, interest and any other charges we may impose in connection with the placement of the insurance, until the effective date of the cancellation or expiration of the insurance. The costs of the insurance may be added to your total outstanding

balance or obligation. The costs of the insurance may be more than the cost of insurance you may be able to obtain on your own.”

If Borrower fails to maintain any insurance required hereunder or under the other Loan Documents or fails to provide evidence of such insurance as required hereunder or under the other Loan Documents, Lender may, but shall not be obligated to, purchase such required insurance at Borrower’s expense to protect its interests in the Property and the Improvements. This insurance may, but need not, protect Borrower’s interests in the Property and the Improvements. The coverage that Lender purchases shall not be required to pay any claim that Borrower makes or any claim that is made against Borrower in connection with the Property and the Improvements. Borrower may later cancel any insurance purchased by Lender, but only after providing evidence that Borrower has obtained the insurance required hereunder and under any other Loan Document. If Lender purchases insurance for the Property and/or the Improvements, Borrower will be responsible for the costs of the insurance, including the insurance premiums, interest thereon from the date of each such payment or expenditure at the then applicable rate under the Construction/Term Loan Note and any other charges Lender may impose in connection with the placement of the insurance, until the effective date of the cancellation or expiration of the insurance. All sums so paid or expended by Lender, the interest thereon and the other charges in connection therewith shall be added to the Loan and shall be secured by the lien of the Leasehold Mortgage. The costs of the insurance obtained by Lender may be more than the cost of insurance Borrower may be able to obtain on its own. Unless Lender otherwise agrees in writing, Borrower shall pay to Lender the full costs of such insurance, together with the accrued interest thereon and the other charges in connection therewith, within thirty (30) days after “Notice of Placement of Insurance” as required by Mo. Rev. Stat. 427.125.

(g) In addition to the insurance requirements under (a) – (f) of this Section 7.10, Borrower shall maintain all insurance required to be maintained pursuant to the terms of the Ground Lease.

7.11 Governmental Requirements. Borrower will comply with all Environmental Laws and all land use, building, subdivision, zoning, OSHA, pollution, sales practices laws, regulations and similar laws, rules, ordinances and regulations promulgated by any governmental authority and applicable to Borrower’s business, the Property, its development and construction of Improvements and the operation thereof, except where the failure to so comply would not reasonably be expected to have a material adverse effect on Borrower, the Improvements, or the Borrower’s ability to pay and/or perform the Obligations.

(b) Borrower shall not, nor shall it permit any Subsidiary to, declare or make, or agree to pay or make, directly or indirectly, any Restricted Payment, or incur any obligation (contingent or otherwise) to do so, except, so long as no Default or Event of Default has occurred and is continuing, the Borrower may pay dividends or make distributions to its members either:

(i) annually within thirty (30) days after Lender has received (1) Borrower’s annual Audited financial statements for the applicable fiscal year on which such dividends and distributions are based and (2) supporting calculations from Borrower in

form satisfactory to Lender in its reasonable discretion to support the amount of the proposed dividends and distributions, or

(ii) quarterly within thirty (30) days after Lender has received (1) for any fiscal quarter other than the last fiscal quarter of the fiscal year for which such dividends and distributions are based, Borrower’s quarterly Reviewed financial statements or internally prepared quarterly financial statements certified by an accountant, which accountant and certificate shall be acceptable to Lender in its sole discretion, for the applicable fiscal quarter for which such dividends and distributions are based, (2) for the last fiscal quarter of the fiscal year for which such dividends and distributions are based, Borrower’s annual Audited financial statements for the fiscal year for which such dividends and distributions are based and (3) supporting calculations from Borrower in form satisfactory to Lender in its reasonable discretion to support the amount of the proposed dividends and distributions;

provided, however, that:

(A) no such dividends or distributions shall be made until the Lender has received Borrower’s financial statements as of the end of the eighth full fiscal quarter following Commencement of Production;

(B) such dividends and distributions shall be permitted only in an amount and to the extent (i) that Borrower’s Fixed Charge Coverage Ratio (measured in accordance with Section 7.33 of this Agreement) would not be less than 1.50 to 1.00 after taking into calculation the amount of the dividends and distributions to be made and (ii) no Default or Event of Default would result after giving effect to such dividend and/or distribution;

(E) If Borrower elects to make dividends and distributions quarterly, then dividends and distributions shall be based upon Borrower’s fiscal year to date Net Income as of the end of such applicable fiscal quarter, provided, that the amount of

7.16 Certificates.

Borrower shall promptly furnish to Lender and the Inspecting Engineer, copies of all change orders, regardless of whether Lender’s approval is required.

The remedies and rights of Lender shall be cumulative and not exclusive of any other remedies of Lender under any other provision of this Agreement or under any other instrument or at law or in equity.

SECTION 9. LENDER’S RIGHT TO COMPLETE.

9.1 Lender’s Right. Upon the occurrence of any Event of Default described in Section 8 which would give Lender the right under this Agreement to refrain from making any further Advance hereunder, Lender, at its sole option (whether or not it exercised any rights under Section 8) but without any obligation upon Lender to do so, may at any time thereafter (1) advance the proceeds of the Loan or any part thereof, or if necessary, sums in excess of the Loan proceeds, to the Project General Contractor, any subcontractor or any person furnishing labor or material in the construction of the Project for the account of Borrower, and the sums so paid or advanced shall for the purposes of this Agreement, be deemed to have been advanced to Borrower pursuant to the provisions hereof; (2) disburse the proceeds of the Project Addition Escrow Account or any part thereof to the Project Addition General Contractor, any subcontractor or any person furnishing labor or material in the construction of the Project Addition, and (3) take possession of the Property and the Improvements together with all materials, equipment and improvements thereon whether affixed to the realty or not, and all Plans and Specifications, which Borrower hereby assigns to Lender, and Lender shall have the right but shall be under no obligation to perform any and all work and labor necessary to complete the Improvements substantially according to the Plans and Specifications and may employ watchmen or take any action it may deem necessary to protect them from depredation or injury.

(e) to cure any breach or failure to perform by Borrower under the Project General Construction Contract for which Project General Contractor has given Borrower and/or Lender notice that Project General Contractor will or intends to either (i) stop work pursuant to the Project General Construction Contract or (ii) terminate such Project General Construction Contract;

(f) to cure any breach or failure to perform by Borrower under the Project Addition General Construction Contract for which Project Addition General Contractor has given Borrower and/or Lender notice that Project Addition General Contractor will or intends to either (i) stop work pursuant to the Project Addition General Construction Contract or (ii) terminate such Project Addition General Construction Contract;

(g) to pay, settle or compromise all existing bills and claims which may be or become liens against the Property or Improvements or as may be necessary or desirable for completion of the Improvements or for the clearance of title;

(i) to do any and every act which Borrower might or could do in its own behalf.

Lender, in its name, or on behalf of Borrower, shall also have power to prosecute and defend all actions and proceedings in connection with the construction of the Improvements on the Property and to take such action and require such performance as it deems necessary. Borrower hereby assigns and quitclaims to Lender all sums unadvanced hereunder conditioned upon the use of said sums in trust for the completion of the Improvements, such assignment to become effective only at the option of Lender upon the occurrence and continuance of an Event of Default described in Section 8. In addition it is agreed that Lender may, at its option, expend money in completing said construction and protecting and preserving the Property, which shall be over and above the total amount of the funds in the Loan fund to the maximum extent permitted by the law of the applicable jurisdiction, and said money when so expended, shall be added to the principal of the Loans and the same, together with interest thereon at the Default Rate, shall be secured by the lien of the Loan Documents and shall be payable by Borrower on demand.

9.3 Lender May Perform Obligations; Further Assurances. Upon the occurrence and during the continuance of and Event of Default, Borrower shall permit Lender, if Lender so elects in its sole discretion, to pay or perform Borrower’s Obligations hereunder or under the other Loan Documents and to reimburse Lender, on demand, or, if Lender so elects, by Lender making either (i) an Advance against the Loan on Borrower’s behalf or (ii) debiting any account maintained by Borrower with Lender for any and all fees and charges due hereunder, including, without limitation, the accounts established by Borrower with Lender pursuant to this

10.4 No Oral Amendments. Neither this Agreement nor any provision hereof may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against whom enforcement of the change, waiver, discharge or termination is sought.

10.5 Additional Remedies. The remedies herein provided shall be in addition to and not in substitution for the rights and remedies which would otherwise be vested in Lender in any Loan Document or in law or equity, all of which rights and remedies are specifically reserved by Lender. The remedies herein provided or otherwise available to Lender shall be cumulative and may be exercised concurrently. The failure to exercise any of the remedies herein provided shall not constitute a waiver thereof nor shall use of any of the remedies hereby provided prevent the subsequent or concurrent resort to any other remedy or remedies. It is intended that all remedies herein provided for or otherwise available to Lender shall continue and be each and all available to Lender until all sums due it by reason of this Agreement have been paid to it in full and all obligations incurred by it in connection with the construction or operation of the Improvements have been fully discharged without loss or damage to Lender.

10.6 No Partner. Lender is not a partner with Borrower or any other party in the building of the Improvements. Lender shall not in any way be liable or responsible by reason of the provisions hereof, or otherwise, for the payment of any claims growing out of the operation of any Improvements.

10.7 The Collateral Documents as Security. The Collateral Documents shall constitute security for all monies advanced by Lender and all obligations incurred by Lender in excess of the Loans advanced or incurred by Lender pursuant to the authority of this Agreement; and all such monies advanced and obligations incurred shall constitute a lien upon Borrower’s

interest in the Property and Improvements secured by the Collateral Documents and recovery therefore may be had by Lender upon the Collateral Documents in addition to all other remedies herein granted to Lender.

10.8 Usury Savings. Notwithstanding any provision herein or in any other Loan Document, the total liability of Borrower for any payments of interest or in the nature of interest shall not exceed the limits imposed by the usury laws of the State of Missouri. In the event that such payment is paid by Borrower or received by Lender, then such excess sum shall be credited as a payment of the principal amount of the Obligations, unless Borrower shall notify Lender, in writing, that they elect to have such excess sum returned forthwith. Such return or credit shall not cure or waive any Event of Default under this Agreement, the Leasehold Mortgage or any other Loan Document.

10.9 Assignment by Lender. Lender may pledge or otherwise hypothecate or may assign in whole or in part, or issue participating interests in amounts of up to $10,000,000 in the aggregate, in and to this Agreement and any of its rights and security hereunder, and the Notes, the Leasehold Mortgage and all other Loan Documents, to any other person, firm or corporation provided that all of the provisions of this Agreement shall continue to apply to the Loans, the Notes, the Leasehold Mortgage and the other Loan Documents. In the event of such assignment, it shall be deemed in compliance by Lender with this Agreement and to have been made in pursuance of this Agreement and not to be in modification hereof and the Advances made by any such assignee shall be evidenced and secured by the Notes, and the Leasehold Mortgage. In the case of any such transfer, whether by assignment, issuance of participations, pledge, or hypothecation, by Lender, Borrower will accord full recognition thereto and agrees that all rights and remedies of Lender in connection with the interest so transferred shall be enforceable against Borrower by such institution with the same force and effect and to the same extent as the same would have been enforceable by Lender but for such transfer.

10.10 Signs. Borrower agrees, upon Lender’s request, to erect and maintain a sign in form acceptable to Lender on the Property during construction of the Improvements which indicates that Lender is providing construction financing for the Biodiesel Plant.

10.11 Additional Documents. Borrower agrees upon demand to do any act or execute any additional documents (including, but not limited to, security agreements on any personalty included or to be included in the Property or the Improvements) as may be reasonably required by Lender to secure the Notes, to confirm the lien of the Leasehold Mortgage, or any other applicable Loan Document, or to otherwise create, evidence, assure or enhance Lender’s rights and remedies under, or as contemplated by, the Loan Documents or at law or in equity. All of said documents shall be in form and substance prepared by or acceptable to Lender.

10.12 Binding Effect; Continuing Agreement. The terms, conditions, covenants, agreement, powers, privileges, notices and authorizations herein contained shall extend to, be binding upon and available to the heirs, executors, administrators, successors and, to the extent permitted hereunder, the assigns of each of the respective parties hereto. Notwithstanding the foregoing, Borrower shall not, without the prior written consent of Lender, assign or transfer voluntarily or by operation of law this Agreement. An assignment or transfer in violation of this provision shall be invalid and of no force or effect. Borrower’s obligations, covenants,

representations and warranties hereunder shall continue beyond the final disbursement of the Loan made hereunder for so long as Borrower has any obligations outstanding Lender, or Lender has any lien on any property of Borrower.

10.13 Governing Law. This Agreement and each transaction consummated hereunder shall be deemed to be made under the laws of the State of Missouri and shall be construed in accordance with and governed by the laws of such State.

10.14 Headings. The titles and headings of the paragraphs of this Agreement have been inserted for convenience of reference only and are not intended to summarize or otherwise describe, or limit, modify or expound upon the subject matter of such paragraphs.

10.15 Lender’s Discretion. Any condition of this Agreement which requires the submission of evidence of the existence or non-existence of a specified fact or facts implies as a condition the existence or non-existence, as the case may be, of such fact or facts and Lender shall, at all time, be free independently to establish to its satisfaction and in its reasonable discretion such existence or non-existence. Except as otherwise expressly provided in this Agreement, whenever Lender’s judgment, consent or approval is required hereunder for any matter, or Lender shall have an option or election hereunder, such judgment, the decision as to whether or not to consent to or approve the same or the exercise of such option or election shall be in the sole discretion of Lender.

10.16 Consent to Forum. As part of the consideration for new value this day received, Borrower hereby consents to the jurisdiction of any state court located within St. Louis County, Missouri or the United States District Court, Eastern District of Missouri, Eastern Division, and waives personal service of any and all process upon Borrower and consents that all such service of process be made by certified or registered mail directed to Borrower at the address set forth in the preliminary statements hereof, and service so made shall be deemed to be completed upon actual receipt thereof. Nothing contained herein should be deemed to affect the parties’ right to remove to Federal Court within the Eastern District of Missouri. Borrower waives any objection to jurisdiction and venue of any action instituted against Borrower as provided herein and agrees not to assert any defense based on lack of jurisdiction or venue. Borrower further agrees not to assert against Lender (except by way of a defense or counterclaim in a proceeding initiated by Lender) any claim or other assertion of liability with respect to this Agreement, the Notes, any of the Loan Documents, Lender’s conduct in respect of any of the foregoing or otherwise in any jurisdiction other than the foregoing jurisdictions. Nothing in this section shall affect the right of Lender to serve legal process in any other manner permitted by law or affect the right of Lender to bring any action or proceeding against Borrower in the courts of any other jurisdictions.

10.17 Waiver of Jury Trial. TO THE FULLEST EXTENT PERMITTED BY LAW, AND AS SEPARATELY BARGAINED FOR CONSIDERATION TO LENDER, BORROWER HEREBY WAIVES ANY RIGHT TO TRIAL BY JURY (WHICH LENDER ALSO WAIVES) IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM OF ANY KIND ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE NOTES, ANY OF THE LOAN DOCUMENTS OR LENDER’S CONDUCT IN RESPECT OF ANY OF THE FOREGOING.

All of the terms of the other Loan Documents are incorporated in and made part of this Loan Agreement by reference. Pursuant to Mo. Rev. Stat. Section 432.047, Lender hereby gives the following notice to Borrower:

To protect you (borrower(s)) and us (creditor) from misunderstanding or disappointment, any agreements we reach covering such matters are contained in this writing, which is the complete and exclusive statement of the agreement between us, except as we may later agree in writing to modify it.”
