(b) Excess Cash Flow. Such term loan shall require that, beginning with the first calendar quarter following the Construction Loan Maturity Date, and continuing throughout the term of the Term Loan, the Borrower shall remit to Lender, in addition to all other installments of principal and interest, an amount equal to 50% of the Borrower’s Excess Cash Flow for the immediately preceding calendar quarter (the “Excess Cash Flow Payment”), provided however, that the total Excess Cash Flow Payments required hereunder shall not exceed $5,000,000.00 in any calendar year. All Excess Cash Flow Payments shall be applied to the reduction of the outstanding principal balance of the Revolving Term Loan. No Excess Cash Flow Payments shall be required during any calendar year should the Tangible Owner’s Equity be greater than 60% at the end of the immediately preceding fiscal year of the Borrower.

(c) Principal Payment Suspension. Principal payments may be suspended by prepaying up to four quarterly term loan principal payments under the Term Loan. At any subsequent time to the prepayment during the course of the term of the loan Borrower may skip as many quarterly principal payments as have been prepaid (up to four) as long as all loan covenants are in compliance. Interest payments will continue to be paid according to the original amortization and due dates.

Section 2.05. Adjustments to Interest Rate. Notwithstanding any other provision of this Agreement, the Supplements, the Notes, or the Related Documents, after the Construction

Loan Maturity Date, the rate of interest under any Loan which bears interest on a variable rate, shall be adjusted according to the following schedule should the Tangible Owner’s Equity of the Borrower, achieve the levels set forth below:


Tangible Owner’s Equity		Interest Rate

Less than 49.99%		Applicable LIBOR Rate plus 325 basis points

50.00%—59.99%		Applicable LIBOR Rate plus 300 basis points

Greater Than 60.00%		Applicable LIBOR Rate plus 275 basis points

Upon delivery of the monthly financial statements and the Compliance Certificate pursuant to Section 5.01(c)(iii) for each month that corresponds with each month end, the rate of interest for any month shall automatically be adjusted in accordance with the Tangible Owner’s Equity set forth therein and the rates set forth above. Such automatic adjustment to the rate of interest shall take effect as of the first Business Day of the month in which the Lender received the related Compliance Certificate. The term “Adjustment Date” shall mean each such Business Day when such rates, margins or fees change pursuant to the immediately prior sentence or the next following sentence. If the Borrower fails to deliver such Compliance Certificate which so sets forth the Tangible Owner’s Equity within the period of time required by Section 5.01(c)(iii) hereof or if any Event of Default occurs, the rate of interest shall automatically be adjusted to a rate equal to the applicable LIBOR Rate plus 375 basis points, such automatic adjustments: (a) to take effect as of the first Business Day after the last day on which the Borrower were required to deliver the applicable Compliance Certificate in accordance with Section 5.01(c)(iii) hereof or in the case of an Event of Default, on the date the written notice is given to the Borrower; and (b) to remain in effect until subsequently adjusted in accordance herewith upon the delivery of such Compliance Certificate or, in the case of an Event of Default, when such Event of Default has been cured to the satisfaction of the Lender.

Section 2.06. Underwriting/Participation/Facility Fees. The Borrower agrees to pay to the Lender on the Closing Date: (i) a Underwriting Fee of $70,000.00, less any amount of this underwriting fee already paid by Borrower; and (ii) a Participation Fee of $489,000.00. In addition, the Borrower shall pay to Lender on or before the Construction Loan Maturity Date, and on each anniversary of the Construction Loan Maturity Date through the fourth anniversary, an annual Facility Fee of $35,000.00, provided that in the event the loans are refinanced, accelerated or for any other reason do not reach the Maturity Date, the Lender shall be entitled to payment of the total amount of such Facility Fees in an amount not less than $175,000.00.

Section 2.07. Default Interest. In addition to the rights and remedies set forth above and notwithstanding any Note: (i) if the Borrower fails to make any payment to Lender when due (including, without limitation, any purchase of equity of Lender when required), then at

Lender’s option in each instance, such obligation or payment shall bear interest from the date due to the date paid at 2% per annum in excess of the rate of interest that would otherwise be applicable to such obligation or payment; (ii) upon the occurrence and during the continuance of an Event of Default beyond any applicable cure period, if any, at Lender’s option in each instance, the unpaid balances of the Loans shall bear interest form the date of the Event of Default or such later date as Lender shall elect at 2% per annum in excess of the rate(s) of interest that would otherwise be in effect on the Loans under the terms of the applicable Note; (iii) after the maturity of any Loan, whether by reason of acceleration or otherwise, the unpaid principal balance of the Loan (including without limitation, principal, interest, fees and expenses) shall automatically bear interest at 2% per annum in excess of the rate of interest that would otherwise be in effect on the Loan under the terms of the applicable Note. Interest payable at the Default Rate shall be payable from time to time on demand or, if not sooner demanded, on the last day of each calendar month.

Section 2.08. Late Charge. If any payment of principal or interest due under the Supplements or the Notes is not paid within ten (10) days of the due date thereof, the Borrower shall, in addition to such amount, pay a late charge equal to five percent (5%) of the amount of such payment.

Section 2.09. Prepayment of Term Loan. The Borrower may, by notice to the Lender, prepay the outstanding amount of the Term Loan in whole or in part with accrued interest to the date of such prepayment on the amount prepaid, without penalty or premium, except as provided in this Section and Section 2.16. In the event the Term Loan is prepaid, in whole or in part, within two (2) years following the Closing Date, the Borrower shall pay a prepayment fee equal to the following specified percentage of the amount of principal prepaid:


Months 1-12	2.00	%
Months 13-24	1.00	%

Notwithstanding the foregoing, no prepayment fee shall be required if such prepayment is made pursuant to Section 2.04(b) of this Agreement. Any prepayment does not otherwise affect Borrower’s obligation to pay any fees due under this Agreement. In addition, in the event any Loan is converted to a fixed rate loan, the Borrower shall pay the prepayment penalty applicable to that fixed interest rate, if any.

Section 2.10. Changes in Law Rendering Certain LIBOR Rate Loans Unlawful. In the event that any change in any applicable law (including the adoption of any new applicable law) or any change in the interpretation of any applicable law by any judicial, governmental or other regulatory body charged with the interpretation, implementation or administration thereof, should make it (or in the good-faith judgment of the Lender should raise a substantial question as to whether it is) unlawful for the Lender to make, maintain or fund LIBOR Rate Loans, then: (a) the Lender shall promptly notify each of the other parties hereto; and (b) the obligation of the Lender to make LIBOR rate loans of such type shall, upon the effectiveness of such event, be suspended for the duration of such unlawfulness. During the period of any suspension, Lender

shall make loans to Borrower that are deemed lawful and that as closely as possible reflect the terms of this Agreement.

Section 2.11. Payments and Computations.

(a) Method of Payment. Except as otherwise expressly provided herein, all payments of principal, interest, and other amounts to be made by the Borrower under the Loan Documents shall be made to the Lender in U.S. dollars and in immediately available funds, without set-off, deduction, or counterclaim, not later than 2:00 P.M. (Minneapolis, Minnesota time) on the date on which such payment shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). The Borrower shall, at the time of making each such payment, specify to the Lender the sums payable under the Loan Documents to which such payment is to be applied and in the event that the Borrower fail to so specify or if an Event of Default exists, the Lender may apply such payment and any proceeds of any Collateral to the Loan Obligations in such order and manner as it may elect in its sole discretion.

(b) Application of Funds. Lender may apply all payments received by it to the Loan Obligations in such order and manner as Lender may elect in its sole discretion; provided that any payments received from any guarantor or from any disposition of any collateral provided by such guarantor shall only be applied against obligations guaranteed by such guarantor.

(c) Payments on a Non-Business Day. Whenever any payment under any Loan Document shall be stated to be due on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of the payment of interest and fees, as the case may be.

(d) Proceeds of Collateral. All proceeds received by the Lender from the sale or other liquidation of the Collateral when an Event of Default exists shall first be applied as payment of the accrued and unpaid fees and expenses of the Lender hereunder, including, without limitation, under Section 7.04 and then to all other unpaid or unreimbursed Loan Obligations (including reasonable attorneys’ fees and expenses) owing to the Lender and then any remaining amount of such proceeds shall be applied to the unpaid amounts of Loan Obligations, until all the Loan Obligations have been paid and satisfied in full or cash collateralized. After all the Loan Obligations (including without limitation, all contingent Loan Obligations) have been paid and satisfied in full, all Commitments terminated and all other obligations of the Lender to the Borrower otherwise satisfied, any proceeds of Collateral shall be delivered to the Person entitled thereto as directed by the Borrower or as otherwise determined by applicable law or applicable court order.

(e) Computations. Except as expressly provided otherwise herein, all computations of interest and fees shall be made on the basis of actual number of days lapsed over a year of 365 or 366 days, as appropriate. Interest shall accrue from and include the date of borrowing, but exclude the date of payment.

Section 2.12. Maximum Amount Limitation. Anything in this Agreement, any Supplement, any Note, or the other Loan Documents to the contrary notwithstanding, Borrower shall not be required to pay unearned interest on any Note or any of the Loan Obligations, or ever be required to pay interest on any Note or any of the Loan Obligations at a rate in excess of the Maximum Rate, if any. If the effective rate of interest which would otherwise be payable under this Agreement, any Note or any of the other Loan Documents would exceed the Maximum Rate, if any, then the rate of interest which would otherwise be contracted for, charged, or received under this Agreement, any Note or any of the other Loan Documents shall be reduced to the Maximum Rate, if any. If any unearned interest or discount or property that is deemed to constitute interest (including, without limitation, to the extent that any of the fees payable by Borrower for the Loan Obligations to the Lender under this Agreement, any Supplement, any Note, or any of the other Loan Documents are deemed to constitute interest) is contracted for, charged, or received in excess of the Maximum Rate, if any, then such interest in excess of the Maximum Rate shall be deemed a mistake and canceled, shall not be collected or collectible, and if paid nonetheless, shall, at the option of the holder of such Note, be either refunded to the Borrower, or credited on the principal of such Note. It is further agreed that, without limitation of the foregoing and to the extent permitted by applicable law, all calculations of the rate of interest or discount contracted for, charged or received by the Lender under its Note, or under any of the Loan Documents, that are made for the purpose of determining whether such rate exceeds the Maximum Rate applicable to the Lender, if any, shall be made, to the extent permitted by applicable laws (now or hereafter enacted), by amortizing, prorating and spreading during the period of the full terms of the Advances evidenced by the Notes, and any renewals thereof all interest at any time contracted for, charged or received by Lender in connection therewith. This Section 2.11 shall control every other provision of all agreements among the parties to this Agreement pertaining to the transactions contemplated by or contained in the Loan Documents, and the terms of this Section 2.11 shall be deemed to be incorporated in every Loan Document and communication related thereto.

Section 2.13. Lender Records. All advances and all payments or prepayments made thereunder on account of principal or interest may be evidenced by the Lender in accordance with its usual practice in an account or accounts evidencing such advances and all payments or prepayments thereunder from time to time and the amounts of principal and interest payable and paid from time to time thereunder; in any legal action or proceeding in respect of the Notes, the entries made in such account or accounts shall be prima facie evidence of the existence and amounts of all advances and all payments or prepayments made thereunder on account of principal or interest. Lender shall provide monthly statements of such entries to Borrower for the purpose of confirming the accuracy of such entries.

Section 2.14. Loan Payments. During the continuance of an Event of Default, the Lender may deduct any obligations due or any other amounts due and payable by the Borrower under the Loan Documents from any accounts maintained with the Lender.

Section 2.15. Purchase of Equity Interests in AgStar Financial Services, PCA. In addition to (and not in lieu of) the other amounts payable by Borrower under this Agreement or

any Supplement, Borrower shall purchase $1,000.00 of equity interests in AgStar Financial Services, PCA. The purchase price for the equity interests shall be payable in full on or prior to the date hereof. Such purchases of equity interests shall comply with AgStar Financial Services, PCA’s respective by-laws and capital plans applicable to borrowers generally. Borrower hereby acknowledges receipt of the following information and materials pertaining to AgStar Financial Services, PCA prior to the execution of this Agreement: (i) copies of the by-laws of AgStar Financial Services, PCA; (ii) a written description of the terms and conditions under which the equity interests are issued; (iii) a copy of the most recent annual reports of AgStar Financial Services, PCA; and (iv) if more recent than the latest annual reports, the latest quarterly reports of AgStar Financial Services, PCA. AgStar Financial Services, PCA shall possess a statutory security interest in its equity interests. AgStar Financial Services, PCA reserves the right to sell participations on a non-patronage basis.

Borrower acknowledges and agrees that: (a) only the portions of the Loans provided to Borrower by AgStar Financial Services, PCA are entitled to patronage distributions in accordance with the bylaws of AgStar Financial Services, PCA and its practices and procedures; and (b) any patronage or similar payments to which Borrower is entitled as a result of its ownership of the equity interests in AgStar Financial Services, PCA will not be based on any of the Loans not belonging to AgStar Financial Services, PCA or in which AgStar Financial Services, PCA has granted a participation interest at any time.

Section 2.16. Compensation. Upon the request of the Lender, the Borrower shall pay to the Lender such amount or amounts as shall be sufficient (in the reasonable opinion of the Lender) to compensate it for any loss, cost, or expense (excluding loss of anticipated profits incurred by it) as a result of: (i) any payment, prepayment, or conversion of a LIBOR rate loan for any reason on a date other than the last day of the Interest Period for such Loan; or (ii) any failure by the Borrower for any reason (including, without limitation, the failure of any condition precedent specified in Section 3.01 to be satisfied) to borrow, extend, or prepay a LIBOR rate loan on the date for such borrowing, extension, or prepayment specified in the relevant notice of borrowing, extension or prepayment under this Agreement.

Such indemnification may include any amount equal to the excess, if any, of: (a) the amount of interest which would have accrued on the amount so prepaid, or not so borrowed, converted or extended, for the period from the date of such prepayment or of such failure to borrower, convert or extend to the last day of the applicable Interest Period (or in the case of a failure to borrow, convert or extend, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such loan as provided for herein; over (b) the amount of interest (as reasonably determined by the Lender) which would have accrued to the Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank LIBOR market. The covenants of the Borrower set forth in this Section 2.16 shall survive the repayment of the Loans and other obligations under the Loan Documents hereunder.

the ordinary course of and pursuant to the reasonable requirements of the business of the Borrower or any of its subsidiaries and upon fair and reasonable terms which are fully disclosed to Lender and are no less favorable to the Borrower or such subsidiary than would be obtained in a comparable arm’s length transaction with a person or entity that is not an Affiliate, and (iii) payment of compensation to directors, officers and employees in the ordinary course of business for services actually rendered in their capacities as directors, officers and employees, provided such compensation is reasonable and comparable with compensation paid by companies of like nature and similarly situated.

Directly or indirectly pay any management, consulting or other similar fees to any person, except legal or consulting fees paid to persons or entities that are not Affiliates of the Borrower or its subsidiaries for services actually rendered and in amounts typically paid by entities engaged in the Borrower’s or such subsidiary’s business. Not withstanding the foregoing and only with the prior written consent of the Lender, a management fee of up to 5% of the Borrower’s EBITDA for the immediately proceeding fiscal year may be paid by the Borrower after the Lender has determined that all applicable covenants will be met after the distribution of the management fee; or

(m) Material Control or Management. (i) One or more of the members of the Borrower as of the date hereof shall fail, in the aggregate, to own, directly or indirectly, 100% of the common (voting) membership interests in the Borrower, or (ii) there should be any change in the chief executive officer of the Borrower, unless within 90 days of such event a person reasonably acceptable to Lender is appointed to such position.

(s) The Borrower should terminate, change, amend or restate, without the Lender’s prior consent any Material Contract, or any material Construction Contract.

(a) may accelerate the due date of the unpaid principal balance of the Notes, all accrued but unpaid interest thereon and all other amounts payable under this Agreement making such amounts immediately due and payable, whereupon the Notes, all such interest and all such amounts shall become and be forthwith immediately due and payable, without presentment, notice of intent to accelerate or notice of acceleration, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Borrower; provided, however, that in the event of an actual or deemed entry of an order for relief with respect to any of the Borrower under the Federal Bankruptcy Code, the Notes, all such interest and all such amounts shall automatically become due and payable, without presentment, demand, protest or any notice of any kind, all of which are hereby expressly waived by the Borrower;

(b) may withhold or direct the Disbursing Agent to withhold any one or more Advances in its discretion, and terminate the Lender’s obligations, if any, under this Agreement to make any Advances whereupon the commitment and obligations of the Lender to extend credit or to make Advances hereunder shall terminate, and no disbursement of Loan funds by the Lender will cure any default of the Borrower, unless the Lender agrees otherwise in writing;

(c) may, by notice to the Borrower, obtain the appointment of a receiver to take possession of all Collateral of the Borrower, including, but not limited to all personal property, including all fixtures and equipment leased, occupied or used by any of the Borrower. Borrower hereby irrevocably consents to the appointment of such receiver and agrees to cooperate and assist any such receiver as reasonably requested to facilitate the transfer of possession of the Collateral to such receiver and to provide such receiver access to all books, records, information and documents as requested by such receiver;

(d) in its discretion, enter the Real Property and take any and all actions necessary in its judgment to complete construction of the Project, including but not limited to making changes in Plans and Specifications, work or materials, and entering into, modifying, or

terminating any contractual arrangements, subject to the Lender’s right at any time to discontinue any work without liability. If the Lender elects to complete the Project, it will not assume any liability to the Borrower or any other person for completing the Project or for the manner or quality of construction of the Project, and the Borrower expressly waives any such liability. The Borrower irrevocably appoints the Lender as its attorney-in-fact, with full power of substitution, to complete the Project in the Borrower’s name, or the Lender may elect to complete construction in its own name. In any event, all sums expended by the Lender in completing construction will be considered to have been disbursed to the Borrower and will be secured by the Mortgage and any other instruments or documents securing the Loans, and any such sums that cause the principal amount of the Loans to exceed the face amount of the Notes will be considered to be an additional loan to the Borrower bearing interest at the rate provided in the Notes and will be secured by the Mortgage and any other instrument or documents securing the Loans. The Lender will not have any obligation under the Plans and Specifications prepared for the Project, any studies, data, and drawings with respect thereto prepared by or for Borrower, or the contracts and agreements relating to the Plans and Specifications, or the aforesaid studies, data, and drawings, or to the construction of the Project unless it expressly hereafter agrees in writing. The Lender will have the right to exercise any rights of the Borrower under those contracts and agreements or with respect to such Plans and Specifications, studies, data, and drawings upon any default by the Borrower under this Agreement, and shall have such other rights and remedies with respect thereto as are afforded a secured creditor under applicable law; and

(e) may, by notice to the Borrower, require the Borrower to pledge to the Lender as security for the Loan Obligations an amount in immediately available funds equal to the then outstanding Letter of Credit Liabilities, such funds to be held in an interest bearing cash collateral account at the Lender without any right of withdrawal by the Borrower; provided, however, that in the event of an actual or deemed entry of an order for relief with respect to the Borrower or any of its subsidiaries under the Federal Bankruptcy Code, the Borrower shall, without notice, pledge to the Lender as security for the Loan Obligations an amount in immediately available funds equal to the then outstanding Letter of Credit Liabilities, such funds to be held in such an interest bearing cash collateral account at the Lender; and

(f) may exercise all other rights and remedies afforded to the Lender under the Loan Documents or by applicable law or equity.

Section 6.03. Remedies Cumulative. Each and every power or remedy herein specifically given shall be in addition to every other power or remedy, existing or implied, given now or hereafter existing at law or in equity, and each and every power and remedy herein specifically given or otherwise so existing may be exercised from time to time and as often and in such order as may be deemed expedient by Lender, and the exercise or the beginning of the exercise of one power or remedy shall not be deemed a waiver of the right to exercise at the same time or thereafter any other power or remedy. No delay or omission of Lender in the exercise of any right or power accruing hereunder shall impair any such right or power or be construed to be a waiver of any default or acquiescence therein.

Section 7.04. Costs, Expenses and Taxes.

(a) The Borrower agrees, jointly and severally, to pay on demand all costs and expenses in connection with the preparation, execution, delivery, filing, recording and administration of the Loan Documents and the other documents to be delivered under the Loan Documents, including, without limitation, the reasonable fees and out-of-pocket expenses of counsel for the Lender (who may be in-house counsel), and local counsel who may be retained by said counsel, with respect thereto and with respect to advising the Lender as to its respective rights and responsibilities under the Loan Documents, and all costs and expenses (including reasonable counsel fees and expenses) for the Lender in connection with the filing of the Financing Statements and the enforcement of the Loan Documents and the other documents to be delivered under the Loan Documents, including, without limitation, in the context of any bankruptcy proceedings. In addition, the Borrower agrees to pay on demand the expenses described in Section 5.01(b). In addition, the Borrower shall pay any and all stamp and other taxes and fees payable or determined to be payable in connection with the execution, delivery, filing and recording of the Loan Documents and the other documents to be delivered under the Loan Documents, and agrees to save the Lender harmless from and against any and all liabilities with respect to or resulting from any delay in paying or omission to pay such taxes and fees.

(b) If, due to payments made by the Borrower pursuant to Section 2.06 or due to acceleration of the maturity of the Advances pursuant to Section 6.01 or due to any other reason, the Lender receives payments of principal of any Loan other than on the last day of an Interest Period relating thereto, the Borrower shall pay to the Lender on demand any amounts required to compensate the Lender for any additional losses, costs or expenses which it may incur as a result of such payment, including, without limitation, any loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by the Lender to fund or maintain such Loan.

Section 7.05. Right of Set-off. The Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by the Lender to or for the credit or the account of the Borrower against any

and all of the Loan Obligations, irrespective of whether or not the Lender shall have made any demand under such Loan Document and although deposits, indebtedness or such obligations may be unmatured or contingent. The Lender agrees promptly to notify the Borrower after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Lender under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Lender may have.

Section 7.06. Severability of Provisions. Any provision of this Agreement or of any other Loan Document which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or thereof or affecting the validity or unenforceability of such provision in any other jurisdiction.

Section 7.07. Binding Effect; Successors and Assigns; Participations.

(a) This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign or otherwise transfer its rights hereunder or any interest herein without the prior written consent of the Lenders. Upon the request of Borrower, Lender shall provide copies of all invoices for costs and expenses to be reimbursed by Borrower under this Agreement or under any of the Loan Documents.

(b) Borrower agrees and consents to Lender’s sale or transfer, whether now or later, of one or more participation interests in the Loans to one or more purchasers, whether related or unrelated to Lender. Lender may provide, without any limitation whatsoever, to any one or more purchasers, or potential purchasers, any information or knowledge Lender may have about Borrower or about any other matter relating to the Loans, and Borrower hereby waives any rights to privacy it may have with respect to such matters; provided, however, that any information received by any such purchaser or potential purchaser under this provision which concerns the personal, financial or other affairs of the Borrower shall be received and kept by the purchaser or potential purchaser in full confidence and will not be revealed to any other persons, firms or organizations nor used for any purpose whatsoever other than for determining whether or not to participate in the Loans and in accord with the rights of Lender if a participation interest is acquired. Borrower additionally waives any and all notices of sale of participation interests, as well as all notices of any repurchase of such participation interest. Borrower also agrees that the purchasers of any such participation interests will be considered as the absolute owners of such interests in the Loans and will have all the rights granted under the participation agreement or agreements governing the sale of such participation interests. Borrower further waives all rights of offset or counterclaim that it may have now or later against Lender or against any purchaser of such a participation interest arising out of or by virtue of the participation and unconditionally agrees that either Lender or such purchaser may enforce Borrower’s obligation under the Loans irrespective of the failure or insolvency of any holder of any interests in the Loans. Borrower further agrees that the purchaser of any such participation interests may enforce its interests irrespective of any personal claims or defenses that Borrower may have against Lender.

Section 7.08. Consent to Jurisdiction.

(a) The Borrower hereby irrevocably submits to the jurisdiction of any Minnesota state court or federal court over any action or proceeding arising out of or relating to this Agreement, the Note and any instrument, agreement or document related hereto or thereto, and the Borrower hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such Minnesota state court or federal court. The Borrower hereby irrevocably waives, to the fullest extent it may effectively do so, the defense of an inconvenient forum to the maintenance of such action or proceeding. The Borrower irrevocably consents to the service of copies of the summons and complaint and any other process which may be served in any such action or proceeding by the mailing of copies of such process to Borrower at its address specified in Section 7.02. The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(b) Nothing in this Section 7.08 shall affect the right of the Lender to serve legal process in any other manner permitted by law or affect the right of the Lender to bring any action or proceeding against the Borrower or its property in the courts of other jurisdictions.

Section 7.09. Governing Law. THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF MINNESOTA.

Section 7.10. Execution in Counterparts. This Agreement may be executed in any number of counterparts and on telecopy counterparts, each of which when so executed shall be deemed to be an original and all of which when taken together shall constitute but one and the same agreement.

Section 7.11. Survival. All covenants, agreements, representations and warranties made by the Borrower in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Advances and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that Lender may have had notice or knowledge of any Event of Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as any Loan Obligations are outstanding and unpaid and so long as the Lender has any unexpired commitments under this Agreement or the Loan Documents. The expense reimbursement, additional cost, capital adequacy and indemnification provisions of this Agreement shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loan Obligations or the termination of this Agreement or any provision hereof.

Section 7.12. WAIVER OF JURY TRIAL. THE BORROWER AND THE LENDER HEREBY IRREVOCABLY WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENT TO WHICH IT IS A PARTY OR ANY INSTRUMENT OR DOCUMENT DELIVERED THEREUNDER.

P.O. Box 4249
Mankato, MN56002-4249

Re: Master Loan Agreement Dated November ___, 2005 by and between US Bio Albert City, LLC and AgStar Financial Services, PCA

Ladies and Gentlemen:

We have acted as counsel to US Bio Albert City, LLC, an Iowa limited liability company (the “Company”), in connection with the negotiation of the Master Loan Agreement dated November 15, 2005 (the “Loan Agreement”) by and between the Company and Agstar Financial Services, PCA (the “Lender” or “you”) dated as of the date hereof and the consummation of the transactions described therein. This letter is furnished to satisfy a condition set forth in Section 3.01(r) of the Loan Agreement. All capitalized terms used in this letter that are not otherwise defined herein have the meanings assigned to them in the Loan Agreement unless the context requires otherwise.

In our capacity as counsel to the Company, and for purposes of this opinion, we have examined the following documents:

(i) the Loan Agreement;

(ii) the First Supplement to the Loan Agreement;

(iii) the Second Supplement to the Loan Agreement;

(iv) the Construction Note;

(v) the Revolving Note;

(vi) the Security Agreement;

(vii) the Mortgage;

(viii) the Disbursing Agreement;

(ix) the Articles of Organization and Operating Agreement, as amended, of the Company;

(x) the records of proceedings and actions of the members and Board of Managers of the Company with respect to the transactions between you and the Company contemplated by the Loan Agreement;

(xi) such other documents, agreements and materials as we have deemed necessary and appropriate to render the opinions set forth in this letter, subject to the limitations, assumptions and qualifications noted below.

The documents listed as items (i) through (viii) above are dated as of the first date written above and are collectively referred to herein as the “Loan Documents.” In addition, we have examined and relied upon representations and warranties as to matters of fact (other than facts constituting conclusions of law) contained in and made pursuant to the Loan Documents.

In addition, we have examined such other resolutions, documents, certificates and records and have made such investigations of law and fact as we have deemed necessary or appropriate to enable us to render the opinions expressed herein.

In reaching the opinions set forth below, we have assumed, and have not independently verified, the genuineness of all signatures on all documents, the legal capacity and competency for all purposes relevant hereto of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to the authentic originals of all documents submitted to us as copies, the correctness, completeness and accuracy of all facts set forth in all representations, warranties and certificates referred to or identified in this opinion, and that there are no documents, agreements or understandings to which the Lender is a party between the Lender, on the one hand, and the Company on the other hand, other than the Loan Documents, which would have an effect on the opinions set forth below. In examining documents executed by parties other than the Company, we have assumed that such parties had the requisite power, right and authority (corporate or otherwise) to execute, deliver and perform all of their respective obligations thereunder and have also assumed the due authorization by all requisite corporate action and execution and delivery of such documents by such parties, and the validity, legality and binding effect of those documents on those parties. As to questions of fact material to our opinions, we have relied upon the representations and warranties made in the Loan Documents and upon certificates of officers or other representatives of the Company and of public officials (“Certificates”). We have not independently or through third parties verified such representations and warranties or Certificates, or made any independent investigation as to the existence of agreements, instruments or other documents, orders, judgments or decrees by which the Company or any of its properties or assets may be bound.

In basing the opinions and other matters set forth herein on phrases such as “best of our knowledge,” “our knowledge,” or “known to us,” such phrases signify that, in the course of our representation of the Company in matters with respect to which we have been engaged by the Company to give substantive attention as counsel, no information has come to our attention that would give us actual knowledge that any such opinion or other matters are not accurate or that any of the foregoing Certificates and other matters on which we have relied are not accurate and complete. Except as otherwise stated herein, we have undertaken no independent investigation or verification of such matters. The phrases “best of our knowledge,” “our knowledge,” “known

to us” and similar language used herein are intended to be limited to the knowledge of the lawyers currently employed by our firm who have performed substantive legal services related to the Loan Documents and have specific knowledge of the substance of this opinion.

Based on our review of the foregoing, and subject to the assumptions, qualifications and limitations set forth herein, it is our opinion that:

1. The Company is a limited liability company duly organized, validly existing, and in good standing under the laws of the State of Iowa.

2. The Company has the power to enter into and perform its obligations under the Loan Documents.

3. The Company has taken all necessary company action to authorize the execution, delivery, and performance by the Company of the Loan Documents, and the consummation by the Company of the transactions set forth in the Loan Documents.

4. The Loan Documents have been duly and validly executed and delivered by the Company and constitute legal, valid, binding, and enforceable obligations of the Company.

5. The execution and delivery by the Company of the Loan Documents do not, and the consummation by the Company of the transactions contemplated by the Loan Documents and the compliance by the Company with the provisions of the Loan Documents do not, (a) conflict with or result in a breach of any provision of the Company’s Articles of Organization, or Operating Agreement, (b) to our knowledge, conflict with or result in a material violation of any applicable state or federal law or regulation, (c) to our knowledge, conflict with any order, judgment, or decree to which the Company are a party or subject or by which any of its properties or assets are bound, or (d) to our knowledge, conflict with any Material Contract to which the Company is a party or by which the Company or any of its properties or assets are bound.

6. To our knowledge, except as expressly disclosed in the Loan Documents, there are no actions, suits or proceedings pending or threatened in writing against or affecting the Company before any court or arbitrator or by or before any administrative agency or government authority, which, if adversely determined, would constitute an material adverse effect on the Company. We do, however, call your attention to the recently completed private placement of the Company’s sole member US BioEnergy Corporation pursuant to private placement memorandum dated May 31, 2005, and the release of the Company’s equity funds (through contributions by US BioEnergy Corporation) for use in the transactions contemplated by the Loan Documents. We make no opinions herein with respect to the outcome or impact of those matters.

The foregoing opinions are subject to the following qualifications (in addition to the qualifications, exceptions, limitations and assumptions specified above):

A. Our opinions as they relate to the legality, validity, binding effect and/or enforceability of the Loan Documents are subject to the limitations that might result from bankruptcy, insolvency, reorganization, arrangement, moratorium, fraudulent or preferential transfer, fraudulent conveyance, and other state and federal laws relating to or affecting the rights or remedies of creditors generally, now or hereafter, in effect.

B. Our opinions as they relate to the legality, validity, binding effect and/or enforceability of the Loan Documents are subject to the qualification that the availability of the remedies of specific performance or injunctive relief, or any other equitable remedy, is subject to the discretion of the court before which a proceeding therefor may be brought, equitable defenses and the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), including without limitation, concepts of materiality, reasonableness, good faith, fair dealing and other similar doctrines affecting the enforcement of agreements generally.

C. Except as expressly stated herein, no opinion is expressed or implied as to the truth, accuracy or completeness of any of the representations, warranties or other statements of the Company or any other person contained in any of the Loan Documents or in any exhibit, schedule or attachment thereto.

D. We express or imply no opinion as to what actions the parties to the Loan Documents are required to or may take or fail to take on or after the date hereof which, if taken or not taken, would affect or impair the legality, validity, binding effect and/or enforceability of the Loan Documents or the rights and remedies of the parties thereunder.

E. With respect to the legality, validity, binding effect and enforceability of the remedies available to the Lender under the Uniform Commercial Code in force in the State of Minnesota (“UCC”), we have assumed that the Lender will enforce such remedies in accordance with the UCC and under such circumstances and in a manner in which it is commercially reasonable to do so. In addition, because a claimant bears the burden of proof required to support its claim, our opinion assumes that you will undertake the effort and expense necessary to present your claims in the prosecution of any remedy accorded you under the Loan Documents.

F. We express or imply no opinion as to the creation, attachment, perfection or priority of any security interest, mortgage or other lien which the Lender may claim in any real or personal property of the Company under any of the Loan Documents or otherwise.

G. Our opinions as they relate to the legality, validity, binding effect and/or enforceability of the Loan Documents are subject to the limitations arising from state and federal court decisions involving statutes, public policy and/or principles of equity holding that (i) purported waivers of notice, remedies (or the delay in, omission of, or enforcement thereof) or the benefits of statutory provisions or constitutional or common law rights and broadly or vaguely stated provisions waiving rights or waivers of unknown future rights or duties imposed by law are or may be void or unenforceable, (ii) under certain circumstances, provisions declaring that the failure to exercise or delay in exercising rights or remedies will not operate as

a waiver of any such right or remedy are invalid, (iii) provisions declaring that the documents may only be amended or waived in writing may be unenforceable to the extent that an oral agreement or an implied agreement by trade practice or course of conduct has been created modifying one or more provisions of the Loan Documents, (iv) the enforcement of public policy is of a paramount public interest which may prohibit enforcement of certain contractual provisions; (v) the indemnification and exculpation provisions of the Loan Documents may be unenforceable to the extent that the enforcement of such provisions is determined to be against public policy; and (vi) certain other provisions in the Loan Documents, including, without limitation, self-help provisions, provisions that purport to establish evidentiary standards, provisions requiring the payment of a late payment or repayment charge, fee, reinvestment charge, premium or penalty, however denominated, are or may be unenforceable in whole or in part.

H. Since it is necessary for the Lender to elect its proper remedy in certain instances, no opinion is expressed or implied that any cumulative remedy provision contained in any of the Loan Documents is valid or enforceable.

I. No opinion is expressed or implied as to the legality, validity, binding effect or enforceability of (i) any power of attorney granted to the Lender in any of the Loan Documents, or (ii) any document, certificate, agreement or instrument executed or delivered by the Lender pursuant thereto.

J. Minnesota Statutes, Section 290.371, subd. 4, provides that any corporation required to file a Notice of Business Activities Report does not have a cause of action upon which it may bring suit under Minnesota law unless the corporation has filed a Notice of Business Activities Report and that the use of the courts of the State of Minnesota for all contracts executed and all causes of action that arose before the end of any period for which a corporation failed to file a required report is precluded. We note, however, that a court may excuse the failure to file such a report under certain circumstances described in the statute. Insofar as the foregoing opinion may relate to the legality, validity, binding effect and/or enforceability of any agreement under Minnesota law or in a Minnesota court, we have assumed that any party seeking to enforce the agreement has at all times been, and will continue at all times to be, exempt from the requirement of filing a Notice of Business Activities Report or, if not exempt, has duly filed, and will continue to duly file, all Notice of Business Activities Reports.

K. In giving this opinion, we advise you that a Minnesota court may not strictly enforce certain covenants contained in the Loan Documents or allow acceleration of the maturity of the indebtedness evidenced by the Notes if it concludes that such enforcement or acceleration would be unreasonable under the then existing circumstances. We do believe, however, that subject to the limitations expressed elsewhere in this opinion, enforcement or acceleration would be available if an Event of Default occurs as a result of a material breach of a material covenant contained in the Loan Documents.

L. Certain rights, remedies, waivers and indemnities contained in the Loan Documents, in addition to those specifically enumerated above, may be limited or rendered

ineffective by applicable Minnesota laws or judicial decisions governing such provisions, but such laws and judicial decisions do not render the Loan Documents invalid as a whole, and there exist, in the Loan Documents or pursuant to applicable law, legally adequate remedies for a realization of the principal benefits intended to be provided by the Loan Documents.

In addition to the qualifications set forth above, the opinions set forth herein are also subject to the following qualifications:

M. We are members of the Bar of the State of Minnesota. The opinions expressed herein are limited to matters of Minnesota and federal law. We express no opinion with respect to (i) the laws of any other jurisdiction nor any state or federal law or regulation governing AgStar Financial Services, PCA or (ii) the impact of such laws on the Loan Documents or the transactions contemplated thereby. For purposes of this opinion we have assumed that the internal laws (as opposed to the choice of law rules) of the State of Minnesota and applicable federal law would apply and have rendered our opinion on that basis. To the extent that the law of another jurisdiction applies, we have assumed that the law of that jurisdiction would be the same as Minnesota law. We render no opinion as to the enforceability of any choice of law provision.

N. We express no opinion with respect to title to any property, nor do we express any opinion with respect to the existence of encumbrances upon any property or the attachment, validity, perfection or priority of any liens or security interests.

O. Except as explicitly addressed in the numbered opinions above, no opinion is expressed herein as to any of the topics listed under Section 19 “Specific Legal Issues” of the Third-Party Legal Opinion Report, published in 1991 by the Section of Business Law of the American Bar Association.

This opinion is limited to the specific legal issues addressed herein and no opinion is implied or may be inferred beyond the matters expressly set forth herein. Our opinion is rendered to you solely for your benefit in connection with consummation of the transactions set forth in the Loan Documents and may not be quoted in whole or in part, filed publicly or delivered to, or relied upon by any other person without our prior written consent. Our opinion is based upon the state of facts and the law existing and in effect on the date hereof, and we assume no obligation to revise, supplement or update this opinion in any respect at any time subsequent to the date hereof in order to account for any change in the law (whether or not hereinafter enacted or adopted) or future facts, events or circumstances affecting any of the transactions contemplated by any of the Loan Documents.


				Very truly yours,

RECENT DEVELOPMENTS

This Amended and Restated Confidential Private Placement Memorandum amends and restates in its entirety our Confidential Private Placement Memorandum dated January 31, 2005 (the “Memorandum”) relating to the offering for sale of up to 100,000,000 shares of our Class A common stock to accredited investors. The following explains recent developments in our business and our capital structure that occurred after the distribution of the Memorandum that are now reflected in this Amended and Restated Confidential Private Placement Memorandum.

Extension of Offering until September 30, 2005

On April 18, 2005, our Board of Directors extended the duration of this offering. As extended by our Board on April 18, 2005, we intend to terminate the offering on June 30, 2005, but we may extend the offering one or more times in our discretion to no later than September 30, 2005 to raise up to the maximum amount offered.

Issuances of Class A Common Stock; Conversion of Class B Common Stock

As a result of the Acquisition Transactions described below, we issued 1,500,000 shares of our Class A common stock on April 30, 2005 and 5,000,000 shares of our Class A common stock on May 5, 2005. On May 17, 2005, we closed on the options to purchase the land for our proposed ethanol plant in Lake Odessa, Michigan and as payment for the land, we issued 294,000 shares of our Class A common stock to the land holders.

Additionally, on April 18, 2005 and on April 28, 2005, US Bio Resource Group made payments of $500,000 and $750,000, respectively, under its December 2004 subscription agreement for which we issued it an additional 1,515,150 shares and 2,272,727 shares of our Class B common stock, respectively. Immediately following these issuances, US Bio Resource Group had been issued an aggregate of 14,537,877 shares of our Class B common stock and,

upon our receipt of an additional $3,500,000 in subscription payments from US Bio Resource Group pursuant to its December 2004 subscription agreement, would be issued an additional 10,462,123 shares of Class B common stock. On May 25, 2005, US Bio Resource Group elected to convert all shares of our Class B common stock into shares of our Class A common stock. As provided in our articles of incorporation, each share of Class B common stock is convertible into one share of Class A common stock. Upon its conversion, US Bio Resource Group was issued 14,537,877 shares of our Class A common stock and, through its December 2004 subscription agreement, US Bio Resource Group will be issued an additional 10,462,123 shares of Class A common stock upon our receipt of an additional $3,500,000.

Our articles of incorporation further provide that shares of our Class B common stock that are converted may not be reissued. Therefore, following the conversion of Class B common stock into Class A common stock, we had no shares of Class B common stock issued or outstanding and none are available for issuance.

Merger Transaction with Superior Corn Products

On March 31, 2005, we entered into a Transaction Agreement with Superior Corn Products, LLC (“Superior Corn”) pursuant to which we would acquire Superior Corn by merger. Superior Corn was a development-stage company organized to develop, own and operate a 45 million gallon per year dry grind ethanol plant near Lake Odessa, Michigan. The merger was structured as a reverse triangular merger of Superior Corn into a subsidiary we created for the purpose of this acquisition, with Superior Corn as the surviving company in the merger. The effect of the reverse triangular merger is that following the merger Superior Corn is our wholly-owned subsidiary.

On April 30, 2005, we closed the merger transactions with Superior Corn and in connection with the closing, we issued 1,500,000 shares of our Class A common stock to the 21 members of Superior Corn in exchange for all 600 outstanding Superior Corn membership units. As a result, Superior Corn became our wholly-owned subsidiary and we acquired all of the rights, privileges, properties and assets of Superior Corn and became responsible for all of the liabilities and obligations of Superior Corn. In connection with the merger, we adopted an amended and restated operating agreement of Superior Corn as its sole member. This operating agreement is similar to the one we have in place with our US Bio Albert City subsidiary.

In connection with the transaction agreement relating to the merger, we and Superior Corn each made certain customary representations and warranties to each other regarding our respective businesses, capital structures, assets and liabilities. These representations and warranties will survive the closing date for a period of one year. If there is a claim by a third party that arises out of a material breach of Superior Corn’s representations or warranties, the members of Superior Corn’s board of directors are obligated to jointly and severally indemnify us and Superior Corn against all losses and liabilities asserted against either party, which either individually or in the aggregate exceeds $50,000. In connection with this indemnification obligation by the Superior Corn board, each Superior Corn board member pledged to us the shares of our Class A common stock they received in the merger. Except in cases of fraud or intentional misconduct, our sole remedy against the members of Superior Corn’s Board is to foreclose on this pledge.

Acquisition Transaction with United Bio Energy, LLC

Effective May 5, 2005, we closed two transactions resulting in our acquisition of United Bio Energy, LLC (“UBE”). The acquisition transactions were between us, UBE and UBE’s two members, ICM Marketing, Inc. (“ICMM”) and Fagen Management, LLC (“Fagen Management”). ICMM and Fagen Management held 60% and 40%, respectively, of the outstanding voting power of UBE. The primary business of each of ICMM and Fagen Management was their ownership of UBE. UBE provides professional and operational services to ethanol plants through its five subsidiaries and currently provides services to approximately thirteen existing ethanol plants.

The first of the two transactions resulting in the acquisition of UBE was a merger between us and ICMM in which we were the surviving company. In connection with the merger, we issued to ICMM’s three shareholders an aggregate of 3,000,000 shares of our Class A common stock in exchange for all 800 shares of ICMM common stock outstanding. The three shareholders of ICMM were Dave Vander Griend, Jeff Roskam and Randy Ives who received 1,650,000, 1,050,000 and 300,000 shares of our Class A common stock in the merger, respectively, representing their proportionate ownership interest in ICMM. As a result of the merger with ICMM, we acquired all of the rights, privileges, properties and assets of ICMM and became responsible for all of the liabilities and obligations of ICMM.

The second transaction resulting in the acquisition of UBE was a purchase by us of all of the membership interest in UBE held by Fagen Management in exchange for 2,000,000 shares of our Class A common stock. The sole member of Fagen Management is Ron Fagen, our director.

In connection with the transaction agreement and member assignment agreement relating to the acquisition of UBE, the parties each made certain customary representations and warranties to each other regarding their respective businesses, capital structures, assets and liabilities. In the transaction agreement the parties also provided for indemnification by Ron Fagen, Dave Vander Griend, Jeff Roskam and Randy Ives of certain liabilities of UBE and/or ICMM. The agreements regarding the indemnification for these certain liabilities will survive the closing indefinitely. The other representations and warranties will survive the closing date for a period of one year. If there is a claim by a third party that arises out of a material breach of the representations or warranties of UBE or ICMM, the owners of the respective entity are obligated to indemnify us against all losses and liabilities asserted against us, which either individually or in the aggregate exceeds $50,000. The indemnification obligation is pro-rata among the owners of UBE and ICMM based upon their respective ownership of such entity. Further, the indemnification obligation is capped at an amount equal to the value received by each owner (directly or indirectly) in the UBE acquisition transactions. To secure the obligations of the indemnification, each owner has pledged to us the shares of Class A common stock each received in the UBE acquisition transactions.

The effect of our merger with ICMM and our acquisition of UBE membership units from Fagen Management is that we became the sole member of UBE. In connection with the acquisition transaction with UBE, we adopted an amended and restated operating agreement of

UBE as its sole member. This operating agreement is similar to the one we have in place with our US Bio Albert City subsidiary.

The rights and obligations of UBE and its subsidiaries to third parties did not change as a result of our acquisition of UBE. One of the liabilities of UBE Fuels and UBE Ingredients is a revolving loan of up to $15,000,000 from LaSalle Business Credit, LLC (“LaSalle”). As of May 5, 2005, there was approximately $5,850,025 outstanding under the LaSalle loan. Amounts under the loan are secured by the assets of UBE and each of its subsidiaries and guaranteed by each of the UBE subsidiaries. ICM, Inc. and Fagen, Inc. also provided LaSalle a joint limited guaranty for up to $4,000,000 of the loan obligations. ICM, Inc. is controlled by David Vander Griend, our director, and Fagen, Inc. is controlled by Ron Fagen, our director. In connection with the acquisition of UBE, we entered into a contribution and repayment agreement with LaSalle that provides that if UBE makes distributions or dividend payments to us that exceed the amount necessary to cover the tax liability we may incur as a result of our ownership of UBE, we must pay to LaSalle such excess amount. LaSalle has similar agreements in place with UBE and each of its subsidiaries limiting the distributions and dividends that may be received by them to the amount of their respective tax liabilities.

On April 28, 2005, our Board of Directors granted ten-year options to purchase 185,000 shares of our Class A common stock under our 2005 Stock Incentive Plan to management of UBE as incentives for future performance. All options to UBE management have an exercise price of $1.00 and vest with respect to 20% of the underlying shares on the first anniversary of the date of grant and each of the next four anniversaries of the date of grant.

Effective May 5, 2005, we appointed Jeff Roskam as the President of UBE, a position which he held prior to our acquisition of UBE. Also effective May 5, 2005, we appointed David Vander Griend to our Board of Directors, entered into a three-year consulting arrangement with him and granted him an option to purchase our Class A common stock. Further, with the addition of David Vander Griend to our Board, Jill Wilts resigned as a member of our Board of Directors. See “Management – Employment and Consulting Arrangements” for a description of our agreements with Jeff and Dave.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Since our inception, we have engaged in the transactions described below with our directors, officers and shareholders owning more than 5% of our voting securities. Although we believe that these transactions were in our best interests, we cannot assure you that these transactions were entered into on terms as favorable to us as those that could have been obtained in arms-length transactions.

In addition, conflicts of interest exist and may arise in the future because of the relationships between and among our officers, directors, affiliates and us, and the fact that we may, from time to time, enter into transactions with our officers, directors and affiliates. These conflicts of interest are described below. Conflicts of interest could cause our officers and directors to put their own personal interests ahead of ours. We may not be able to resolve

conflicts of interests, or if resolved, the resolution may be less favorable than if it involved unaffiliated parties.

Transactions with related parties and conflicts of interest may adversely affect our business and the value of your investment.

Our Related Parties

Our shareholder, US Bio Resource Group, LLC, has two equal members, Capitaline Advisors, LLC and Global Ethanol, Inc. Gordon Ommen is the sole owner of Capitaline Advisors, LLC. Ron and Diane Fagen own 91.24% of the voting power of Global Ethanol, Inc., with the remaining voting power controlled by approximately 8 other shareholders, some of whom are our directors and executive officers. Ron Fagen is also the sole owner of Fagen, Inc. and Fagen Management, LLC. David Vander Griend, our director, is the principal owner of ICM, Inc.

Private Placement Issuances of Our Common Stock to Related Parties

In November 2004, US Bio Resource Group subscribed for 10,000,000 shares of our common stock at a price of $0.10 per share. On November 2, 2004, November 23, 2004 and December 28, 2004, US Bio Resource Group made payments on this December 2004 subscription agreement totaling $1,000,000 and, in consideration for these payments, we issued to US Bio Resource Group an aggregate of 10,000,000 shares. The proceeds from this private placement were used to capitalize our company and to pay the expenses associated with its formation, organization and initial development of the Albert City ethanol plant.

In December 2004, US Bio Resource Group subscribed for an additional 15,000,000 shares of our common stock at a per share price of $0.33¹/₃ per share. In connection with the amendment and restatement of our Articles of Incorporation in January 2005, each share of common stock sold to US Bio Resource Group in the November and December 2004 subscriptions was automatically reclassified as one share of Class B common stock for a total of 25,000,000 shares of our Class B common stock issuable to US Bio Resource Group.

On December 28, 2004, April 18, 2005 and April 28, 2005, US Bio Resource Group made payments on this December 2004 subscription agreement totaling $1,500,000 and, in consideration for these payments, we issued to US Bio Resource Group an aggregate of 4,537,877 shares of our Class B common stock. Thus, immediately following the last subscription payment on April 28, 2005, we had received $2,500,000 in aggregate subscription proceeds from US Bio Resource Group and had issued to US Bio Resource Group an aggregate of 14,537,877 shares of our Class B common stock therefor.

On May 25, 2005, US Bio Resource Group elected to convert all shares of our Class B common stock into shares of our Class A common stock. As provided in our articles of incorporation, each share of Class B common stock is convertible into one share of Class A common stock. Upon its conversion, US Bio Resource Group was issued 14,537,877 shares of our Class A common stock and, through its December 2004 subscription agreement, US Bio

Resource Group will be issued an additional 10,462,123 shares of Class A common stock upon our receipt of an additional $3,500,000.

Administration of Our 2005 Stock Incentive Plan and Issuances of Options

In January 2005, we issued each of our seven directors and our Chief Financial Officer, Chad D. Hatch, a seven-year option to purchase 30,000 shares of Class A common stock at an exercise price of $1.00 per share in recognition of their services since our inception. Each option vests and becomes exercisable as to 10,000 shares of Class A common stock on each of the first three anniversaries of the date of grant. On April 28, 2005, our Board of Directors granted ten-year options to purchase an aggregate of 185,000 shares of our Class A common stock under our 2005 Stock Incentive Plan to management of UBE as incentives for future performance. All options to UBE management have an exercise price of $1.00 and vest with respect to 20% of the underlying shares on the first anniversary of the date of grant and each of the next four anniversaries of the date of grant. These options were issued under our 2005 Stock Incentive Plan.

Pursuant to the terms of the administrative services agreement between us and US Bio Resource Group, our board has delegated the discretion to determine the persons eligible to receive an award, the type of award and the number of shares underlying the award and the other terms and conditions of such awards consistent with the 2005 Stock Incentive Plan, to US Bio Resource Group. This delegation of authority is with respect to 5,000,000 shares of Class A common stock to be granted as options or other awards. Our board of directors continues to maintain authority over the 5,000,000 shares of Class A common stock currently authorized for awards under the 2005 Stock Incentive Plan and over which US Bio Resource Group has not been delegated any authority. US Bio Resource Group may issue awards under the 2005 Stock Incentive Plan to persons who render services to us or on our behalf, who may be employees of Capitaline Advisors, Global Ethanol or Fagen. No award or option may be granted pursuant to this delegation of authority in consideration for or arising out of any services related to our capital raising activities to persons who are not our employees without our prior approval. Of the total number of shares over which US Bio Resource Group has discretionary authority, up to 4,000,000 shares may be issued as options and the remainder as other awards under the 2005 Stock Incentive Plan. The costs of such awards are in addition to the other costs for such administrative services provided by US Bio Resource Group.

The delegation of authority will automatically terminate and US Bio Resource Group may not grant any awards pursuant to its delegation of authority from and after the earlier of an initial public offering of our stock, a change in control of us (as defined in the 2005 Stock Incentive Plan) or the termination of the administrative services agreement.

In connection with the Acquisition Transactions, we issued shares of our Class A common stock to Fagen Management, LLC, which is controlled by Ron Fagen, one of our directors and a shareholder owning more than 5% of our voting securities. We also entered into a consulting agreement with David Vander Griend and in connection with that consulting arrangement, granted Dave an option to purchase 100,000 shares of our Class A common stock.

Dave is also the president and chief executive officer of ICM, Inc. Dave is a former shareholder of ICMM and in connection with the acquisition of UBE, was appointed as one of our directors. We also entered into a letter agreement with Jeff Roskam, a former shareholder of ICMM, in connection with his appointment as the President of UBE relating to severance and change of control arrangements. See “Management-Employment and Consulting Arrangements” for a description of our agreements with Jeff and Dave.

Moreover, as a result of the Acquisition Transactions, we acquired the businesses of Superior Corn and UBE, each of which had pre-existing relationships with our directors, officers and shareholders owning more than 5% of our voting securities. These pre-existing relationships will continue after the Acquisition Transactions and include:

•		the limited guaranty by Fagen, Inc. and ICM, Inc. of debt of UBE Fuels and UBE Ingredients to LaSalle for a revolving loan of up to $15,000,000;

•		an agreement between Superior Corn and Fagen, Inc. for the construction of an ethanol plant near Lake Odessa, Michigan; and

•		UBE’s clients are ethanol plants, some of which are owned at least in part by or receive services from our directors, officers or shareholders owning 5% or more of our voting securities.

You should review the description of the Acquisition Transactions in this memorandum to further understand these relationships. Although we believe that these transactions were in our best interests, we cannot assure you that these transactions were entered into on terms as favorable to us as those that could have been obtained in arms-length transactions.

Transactions with US Bio Resource Group and Affiliates

Transactions with US Bio Resource Group, LLC

We have entered into an administrative services agreement with US Bio Resource Group, LLC to provide us management and administrative services relating to the development of our business and ethanol plants. Under our management services agreement, US Bio Resource Group will assist us with and advise us on nearly all management and administrative functions of our business, ranging from accounting matters, billing and collections, business planning, tax matters and maintenance of business and corporate records to human resource functions. US Bio Resource Group may contract with Capitaline Advisors, Fagen or its affiliates, or any other third party to provide these services. With our acquisition of UBE, we expect that we or US Bio Resource Group will utilize UBE for some of these services. See “Management’s Plan of Operation – UBE Services Business” for more information regarding the services US Bio Resource Group and UBE will provide to us.

Under the administrative services agreement, we will pay US Bio Resource Group an annual percentage amount of our audited annual earnings before interest, taxes, depreciation and amortization (before deduction of such annual percentage amount) (“EBITDA”) as soon as practicable following the end of our fiscal year, but no later than 105 days following the end of each fiscal year. The following table shows the percentage of EBITDA to be paid to US Bio Resource Group for the periods noted:


Period	EBITDA
Commencement of agreement through December 31, 2011		5	%
January 1, 2012 through December 31, 2013		4	%
January 1, 2014 through termination of agreement		3	%

We will also pay US Bio Resource Group an annual structure charge in an amount to be mutually agreed upon each year (payable in equal monthly installments) to compensate US Bio Resource Group for a portion of its corporate infrastructure expenses. In addition, we will reimburse US Bio Resource Group for all personnel costs of US Bio Resource Group related to providing the above services to us, all out-of-pocket expenses and all amounts charged to US Bio Resource Group by Fagen and Capitaline relating to services provided to us. The agreement also provides that we will indemnify US Bio Resource Group against claims arising from their services to us.

The administrative services agreement has a term ending on December 31, 2016. After this initial term, the administrative services agreement will automatically be renewed on an annual basis for successive one year terms, unless earlier terminated upon notice for breach or at such time as US Bio Resource Group and its affiliates hold less than 5% of the outstanding voting power of us (as measured on the last day of each fiscal year). Even if the administrative services agreement is terminated prior to December 31, 2016, we are still obligated to pay US Bio Resource Group the annual percentage amount based upon EBITDA.

Transactions with Fagen, Inc.

Master Design-Build Letter Agreement

We have entered into a master design-build letter agreement with Fagen pursuant to which Fagen will provide us construction services relating to dry mill fuel grade ethanol plants in the U.S. Pursuant to this letter agreement, Fagen will design/build ethanol plants, utilizing ICM technology, for an agreed-upon lump sum base price per 100 mgy gas-fired fuel ethanol plant and agreed-upon lump sum base price per 50 mgy gas-fired fuel ethanol plant, guaranteed through December 31, 2007 and subject to a volume discount. Following December 31, 2007, Fagen may adjust the lump sum base pricing on design build agreements with us after December 31, 2007 to Fagen’s standard lump sum base price, less the volume discount. We have agreed to use Fagen as our exclusive developer and design-builder in connection with fuel ethanol plants.

In connection with the letter agreement, Fagen has the right to provide us with construction services relating to dry grind fuel grade ethanol plants we wish to have built on

terms no less favorable to us than those we could obtain in arms-length transactions with unrelated third parties.

A committee of our board consisting of two directors who are associated with Capitaline Advisors and one director who is associated with Fagen have the right to review the terms upon which Fagen proposes to provide us services to determine that they are no less favorable than the terms we might obtain from unrelated third parties. Our board will review the membership of the committee from time to time to determine compliance with then-applicable laws relating to approval of transactions between Fagen and us. As used in the letter agreement, the term “Board” means our board of directors or, if the board has delegated its authority to the committee described above, the committee.

In connection with a transaction, if the Board determines that a proposal for services by a party other than Fagen would, if consummated in accordance with its terms, result in the services being provided to us on terms more favorable to us than Fagen’s proposal, we will provide Fagen notice of this superior proposal and provide it an opportunity to match these terms. If Fagen does not agree to provide us services on the terms contained in the superior proposal, we may proceed to engage the party submitting the superior proposal. From time to time, the Board may also conduct a fee review for services to be provided by Fagen and, based upon that review, it may adjust the prices for Fagen’s services to us to the average of the fees charged on the comparable or similar transactions included in the review.

If we proceed with a party other than Fagen for the engineering or design-build services for any project, we must reimburse Fagen for its expenses incurred in connection with the project based upon its standard rate plus all third party costs incurred with respect to the project.

The letter agreement with Fagen terminate at the close of the first fiscal year following the letter agreement in which US Bio Resource Group, together with its affiliates, owns or controls less than 15% of the outstanding voting power of us.

The parties will enter into definitive design-build agreements acceptable to the parties with respect to each facility or project to be developed or constructed.

Administrative Services Agreement

Transactions with Capitaline Advisors, LLC

Right to Future Financial Services

We have entered into a letter agreement with Capitaline Advisors pursuant to which it has a right to provide us financial advisory services in connection with any purchase, acquisition, sale or disposition of any person or any properties or assets of any person having an aggregate transaction value in excess of $5,000,000. For such services, we will pay Capitaline Advisors a fee of 1% of the transaction value, plus its expenses. We have also agreed to engage Capitaline Advisors for financial advisory services in connection with our preparation for any public securities offering by us, with the compensation to Capitaline Advisors for such services to be determined at the time of the offering and subject to a review of the Board, as described below. Capitaline Advisors may choose to decline to provide us services for any transaction.

A committee of our board consisting of two directors who are associated with Fagen and one director who is associated with Capitaline Advisors have the right to review the terms upon which Capitaline Advisors proposes to provide us services to determine that they are no less favorable than the terms we might obtain from unrelated third parties. Our board will review the membership of the committee from time to time to determine compliance with then-applicable laws relating to approval of transactions between Capitaline Advisors and us. As used in the letter agreement, the term “Board” means our board of directors or, if the board has delegated its authority to the committee described above, the committee.

In connection with a transaction, if the Board determines that a proposal for services by a party other than Capitaline Advisors would, if consummated in accordance with its terms, result in the services being provided to us on terms more favorable to us than Capitaline Advisor’s proposal, we will provide Capitaline Advisors notice of this superior proposal and provide it an opportunity to match these terms. If Capitaline Advisors does not agree to provide us services on the terms contained in the superior proposal, we may proceed to engage the party submitting the superior proposal.

From time to time, the Board may also conduct a fee review for services to be provided by Capitaline and, based upon that review, it may adjust the prices for Capitaline Advisor’s services to us to the average of the fees charged on the comparable or similar transactions included in the review.

The provisions of this letter agreement terminate at the close of the first fiscal year following the letter agreement in which US Bio Resource Group, together with its affiliates, owns or controls less than 15% of the outstanding voting power of us.

Administrative Services Agreement

Conflicts of Interest

In addition to the transactions described above that present conflicts of interest among the parties, conflicts of interest could arise from the following relationships, among others:

•		Capitaline Renewable Energy II, a private fund created by Capitaline Advisors for the purpose of investing in this offering, intends to subscribe for Class A common stock in this offering. Capitaline Advisors is the investment advisor for Capitaline Renewable Energy II and therefore, controls the voting and disposition of the shares of Class A common stock purchased by Capitaline Renewable Energy II in this offering. Capitaline Advisors may experience a conflict of interest in acting in our best interest and in acting in the best interest of the investors in Capitaline Renewable Energy II when making decisions regarding the voting and/or disposition of our Class A common stock.

•		The officers and directors of US BioEnergy also serve as officers or directors of Fagen, Global Ethanol or Capitaline Advisors. The demands on the time of these officers and directors due to their attention to the business of Global Ethanol or Capitaline may from time to time compete for their time and attention to our business. In addition, these officers or directors may experience conflicts in attempting to act in the best interest of both US BioEnergy, Global Ethanol, Fagen or Capitaline Advisors.

•		Our directors also serve as directors of other ethanol producers that currently compete or will compete with us. While our directors must devote sufficient time to our business and affairs, our directors may experience conflicts of interest in allocating their time and attention between us and other businesses. Our directors may also acquire financial or other incentives in other businesses, including ethanol producers.

•		We will reimburse our directors and officers for out-of-pocket expenses relating to our business. We do not have a reimbursement policy or guideline for determining what expenses will be reimbursed. We will review and reimburse all reasonable expenses that our directors and officers submit to us.

•		Decisions of our directors and executive officers will affect our EBITDA and because annual payments to US Bio Resource Group under the administrative services agreement is based upon a percentage of EBITDA, these decisions may affect the amount we pay to US Bio Resource Group.

•		Decisions of our directors and executive officers regarding various matters, including expenditures that we make for our business, reserves for accrued expenses, including compensation of officers, compensation of directors and reimbursement of out-of-pocket expenses, awards under the 2005 Stock Incentive Plan, loan covenants, capital improvements and contingencies will affect the amount of cash available for distribution to shareholders and because of their significant ownership of our shares, our directors and executive officers will stand to benefit to a greater degree from any distribution to shareholders.

1. Definitions. As used in this Supplement, the following terms shall have the following meanings. Capitalized terms used and not otherwise defined in this Supplement shall have the meanings attributed to such terms in the MLA.

2. The Construction Loan. On the terms and conditions set forth in the MLA and this First Supplement, Lender agrees to make a Construction Loan to the Borrower (the “Construction Loan”), by means of multiple advances in an amount not to exceed the lesser of (i) $75,000,000.00 or (ii) an amount equal to 60% of the Project Costs (the “Construction Loan Commitment”). Under the Construction Loan, amounts borrowed and repaid or prepaid may not be reborrowed.

3. Purpose. Advances under the Construction Loan may be used to fund the payment of Project Costs, including closing costs and fees associated with the Construction Loan. The Borrower agrees that the proceeds of the Construction Loan are to be used only for the purposes set forth in this Section 3.

4. Interest Rate. Subject to the provisions of Sections 5 and 7 of this First Supplement, the Construction Loan shall bear interest at a rate equal to the LIBOR Rate plus 350 basis points. The computation of interest, amortization, maturity and other terms and conditions of the Construction Loan shall be as provided in the Construction Note, provided, however, in no event shall the applicable rate exceed the Maximum Rate. Such fixed rate of interest shall not be subject to any adjustments under Section 2.05 of the MLA.

5. Default Interest. In addition to the rights and remedies set forth in the MLA: (i) if the Borrower fails to make any payment to Lender when due (including, without limitation, any purchase of equity of Lender when required), then at Lender’s option in each instance, such obligation or payment shall bear interest from the date due to the date paid at 2% per annum in excess of the rate of interest that would otherwise be applicable to such obligation or payment; (ii) upon the occurrence and during the continuance of an Event of Default beyond any applicable cure period, if any, at Lender’s option in each instance, the unpaid balances of the Construction Loan shall bear interest form the date of the Event of Default or such later date as Lender shall elect at 2% per annum in excess of the rate(s) of interest that would otherwise be in effect on the Construction Loan under the terms of the Construction Note; (iii) after the maturity of the Construction Loan, whether by reason of acceleration or otherwise, the unpaid principal balance of the Construction Loan (including without limitation, principal, interest, fees and expenses) shall automatically bear interest at 2% per annum in excess of the rate of interest that would otherwise be in effect on the Construction Loan under the terms of the Construction Note. Interest payable at the Default Rate shall be payable from time to time on demand or, if not sooner demanded, on the last day of each calendar month.

6. Late Charge. If any payment of principal or interest due under this Supplement or the Construction Note is not paid within ten (10) days of the due date thereof, the Borrower shall pay, in addition to such amount, a late charge equal to five percent (5%) of the amount of such payment.

7. Changes in Law Rendering Certain LIBOR Rate Loans Unlawful. In the event that any change in any applicable law (including the adoption of any new applicable law) or any change in the interpretation of any applicable law by any judicial, governmental or other regulatory body charged with the interpretation, implementation or administration thereof, should make it (or in the good-faith judgment of the Lender should raise a substantial question as to whether it is) unlawful for the Lender to make, maintain or fund LIBOR Rate Loans, then: (a) the Lender shall promptly notify each of the other parties hereto; and (b) the obligation of the Lender to make LIBOR rate loans of such type shall, upon the effectiveness of such event, be suspended for the duration of such unlawfulness. During the period of any suspension, Lender shall make loans to Borrower that are deemed lawful and that as closely as possible reflect the terms of the MLA.

8. Payments and Computations.

(b) Application of Funds. Lender may apply all payments received by it to the Borrower’s obligations to Lender in such order and manner as Lender may elect in its sole

discretion; provided that any payments received from any guarantor or from any disposition of any collateral provided by such guarantor shall only be applied against obligations guaranteed by such guarantor.

(d) Proceeds of Collateral. All proceeds received by the Lender from the sale or other liquidation of the Collateral when an Event of Default exists shall first be applied as payment of the accrued and unpaid fees and expenses of the Lender hereunder, including, without limitation, under Section 7.04 of the MLA and then to all other unpaid or unreimbursed Loan Obligations (including reasonable attorneys’ fees and expenses) owing to the Lender and then any remaining amount of such proceeds shall be applied to the unpaid amounts of the Loan Obligations, until all the Loan Obligations have been paid and satisfied in full or cash collateralized. After all the Loan Obligations (including without limitation, all contingent Loan Obligations) have been paid and satisfied in full, all Commitments terminated and all other obligations of the Lender to the Borrower otherwise satisfied, any proceeds of Collateral shall be delivered to the Person entitled thereto as directed by the Borrower or as otherwise determined by applicable law or applicable court order.

7. Maximum Amount Limitation. Anything in the MLA, this First Supplement, or the other Loan Documents to the contrary notwithstanding, Borrower shall not be required to pay unearned interest on the Construction Note or any of the Loan Obligations, or ever be required to pay interest on the Construction Note or any of the Loan Obligations at a rate in excess of the Maximum Rate, if any. If the effective rate of interest which would otherwise be payable under the MLA, this First Supplement, the Construction Note, or any of the other Loan Documents would exceed the Maximum Rate, if any, then the rate of interest which would otherwise be contracted for, charged, or received under the MLA, this First Supplement, the Construction Note, or any of the other Loan Documents shall be reduced to the Maximum Rate, if any. If any unearned interest or discount or property that is deemed to constitute interest (including, without limitation, to the extent that any of the fees payable by Borrower for the Loan Obligations to the Lender under the MLA, this First Supplement, the Construction Note, or any of the other Loan Documents are deemed to constitute interest) is contracted for, charged, or received in excess of the Maximum Rate, if any, then such interest in excess of the Maximum Rate shall be deemed a mistake and canceled, shall not be collected or collectible, and if paid nonetheless, shall, at the option of the holder of the Construction Note, be either refunded to the Borrower, or credited on the principal of the Construction Note. It is further agreed that, without limitation of the foregoing and to the extent permitted by applicable law, all calculations of the rate of interest or discount contracted for, charged or received by the Lender under the Construction Note, or under

any of the Loan Documents, that are made for the purpose of determining whether such rate exceeds the Maximum Rate applicable to the Lender, if any, shall be made, to the extent permitted by applicable laws (now or hereafter enacted), by amortizing, prorating and spreading during the period of the full terms of the Advances evidenced by the Construction Note, and any renewals thereof all interest at any time contracted for, charged or received by Lender in connection therewith. This section shall control every other provision of all agreements among the parties to the MLA pertaining to the transactions contemplated by or contained in the Loan Documents, and the terms of this section shall be deemed to be incorporated in every Loan Document and communication related thereto.

8. Lender Records. All advances and all payments or prepayments made thereunder on account of principal or interest may be evidenced by the Lender in accordance with its usual practice in an account or accounts evidencing such advances and all payments or prepayments thereunder from time to time and the amounts of principal and interest payable and paid from time to time thereunder; in any legal action or proceeding in respect of the Notes, the entries made in such account or accounts shall be prima facie evidence of the existence and amounts of all advances and all payments or prepayments made thereunder on account of principal or interest. Lender shall provide monthly statements of such entries to Borrower for the purpose of confirming the accuracy of such entries.

9. Loan Payments. During the continuance of an Event of Default, the Lender may deduct any obligations due or any other amounts due and payable by the Borrower under the Loan Documents from any accounts maintained with the Lender.

10. Compensation. Upon the request of the Lender, the Borrower shall pay to the Lender such amount or amounts as shall be sufficient (in the reasonable opinion of the Lender) to compensate it for any loss, cost, or expense (excluding loss of anticipated profits incurred by it) as a result of: (i) any payment, prepayment, or conversion of a LIBOR rate loan for any reason on a date other than the last day of the Interest Period for such Loan; or (ii) any failure by the Borrower for any reason (including, without limitation, the failure of any condition precedent specified in the MLA or this First Supplement to be satisfied) to borrow, extend, or prepay a LIBOR rate loan on the date for such borrowing, extension, or prepayment specified in the relevant notice of borrowing, extension or prepayment under this First Supplement.

Such indemnification may include any amount equal to the excess, if any, of: (a) the amount of interest which would have accrued on the amount so prepaid, or not so borrowed, converted or extended, for the period from the date of such prepayment or of such failure to borrower, convert or extend to the last day of the applicable Interest Period (or in the case of a failure to borrow, convert or extend, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such loan as provided for herein; over (b) the amount of interest (as reasonably determined by the Lender) which would have accrued to the Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank LIBOR market. The covenants of the Borrower set forth in this section shall survive the repayment of the Construction Loan and other obligations under the Loan Documents hereunder.

11. Construction Loan Term. The Construction Loan shall run for a period beginning on the Closing Date and ending on the Construction Loan Maturity Date. On the Construction Loan Maturity Date, the amount of the then unpaid principal balance of the Construction Loan and any and all other amounts due and owing hereunder or under any other Construction Loan Document relating to this Construction Loan shall be due and payable, except for that part, if any, of the Construction Loan which is converted into a Term Loan pursuant to the terms of the MLA.

12. Payment and Calculation. The Borrower will pay interest on the Construction Loan (i) quarterly in arrears on first day of each January, April, July and October (each such dated a “Quarterly Payment Date”), commencing on the first Quarterly Payment Date following the date on which the first Advance is made on the Construction Loan, and continuing on each Quarterly Payment Date thereafter until the Construction Loan Maturity Date. If any Quarterly Payment Date is not a Business Day, then the principal installment then due shall be paid on the next Business Day and shall continue to accrue interest until paid.

13. Disbursement of Construction Loan.

(a) Deposit Account. Disbursements of the Construction Loan will be made by the Lender in the manner provided in the Disbursing Agreement. Subject to Section 13(b) below, all disbursements will be made by wire transferring such funds to the deposit account of the Disbursing Agent in the amount of each Draw Request which is approved pursuant to the Disbursing Agreement. All Construction Loan funds will be considered to have been advanced to and received by the Borrower upon, and interest on such funds will be payable by the Borrower from and after, their deposit in such deposit account.

(b) Lender’s Application of Loan Proceeds. Notwithstanding the provisions of Section 13(a), above, the Lender may elect, upon ten (10) days’ notice to the Borrower, to use the Construction Loan funds to pay, as and when due, any Construction Loan fees owing to Lender, interest on the Construction Loan, release charges under prior mortgages on the Property, and legal fees and disbursements of the Lender’s attorneys which are payable by the Borrower, unless Borrower causes such amount(s) to be paid within said ten (10) days. Such

payments may be made, at the option of the Lender, by debiting or charging the Construction Loan funds in the amount of such payments.

(c) Cost Information. All disbursements will be based upon a detailed breakdown of the Project Costs as set forth in the Sworn Construction Statement attached as Exhibit A to the MLA. In the event that the Borrower becomes aware of any change in the approved Project Costs, which would increase the total cost in excess of $50,000.00 above the amount shown on the attached Sworn Construction Statement, the Borrower shall immediately notify the Lender in writing and promptly submit to the Lender for its approval a revised Sworn Construction Statement. No further disbursements need be made by the Disbursing Agent unless and until the revised Sworn Construction Statement is approved. The Lender reserves the right to approve or disapprove any revised Sworn Construction Statement in its reasonable discretion.

(d) Loan in Balance, Deposit of Funds by Borrower. The Borrower shall keep the Loan in balance as provided in this Section. If the Lender at any time reasonably determines that the amount of the undisbursed Construction Loan proceeds will not be sufficient fully to pay for all costs required to complete the construction of the Project in accordance with the approved Plans and Specifications and for all Project Costs to be incurred by the Borrower, whether such deficiency is attributable to changes in the work of construction or in the Plans and Specifications or to any other cause, the Lender may make written demand on the Borrower to deposit in an escrow fund to be established with the Lender an amount equal to the amount of the shortage reasonably determined by the Lender. The Borrower shall then deposit the required funds with the Lender within ten (10) days after the date of the Lender’s written demand. No further disbursements shall be made by the Disbursing Agent until those funds are deposited by the Borrower in the escrow fund. Whenever the Lender has any such funds on deposit in such escrow fund, it shall make all future advances for Project Costs from the escrow fund before making any further advances under the Loan.

(e) Additional Security. The Borrower irrevocably assigns to the Lender and grants to the Lender a security interest in, as additional security for the performance of the Borrower’s obligations under this the MLA and this First Supplement and the Related Documents, its interest in all funds held by the Disbursing Agent, whether or not disbursed, all funds deposited by the Borrower with the Lender under this First Supplement, all governmental permits obtained for the lawful construction of the Project, and all reserves, deferred payments, deposits, refunds, cost savings, and payments of any kind relating to the construction of the Project. Upon any default of the Borrower, the Lender may use any of the foregoing for any purpose for which the Borrower could have used them under this First Supplement or with respect to the construction or financing of the Project. The Lender will also have all other rights and remedies as to any of the foregoing which are provided under applicable law or in equity.

(f) Conditions Precedent to Construction Advances. The Lender’s obligation to make Construction Advances under the Construction Note shall be subject to the terms, conditions and covenants set forth in the MLA and this First Supplement, including, without limitation, the following further conditions precedent:

(i) Representations and Warranties. The representations and warranties set forth in the MLA and this First Supplement are true and correct in all material respects as of the date of the request for any Advance, except as disclosed in writing to the Lender, to the same extent and with the same effect as if made at and as of the date thereof;

(ii) Draw Request. The Borrower has submitted to the Lender and the Disbursing Agent a Draw Request for each such Advance, which such Draw Request shall comply with the requirements contained in this the MLA, this Supplement and the Disbursing Agreement;

(iii) Compliance With Disbursing Agreement. All of the terms and conditions of the Disbursing Agreement have been satisfied with respect to each such Advance;

(iv) Sworn Construction Statement. The Borrower shall furnish to the Lender an updated Sworn Construction Statement setting forth the Contractor(s) providing services or materials with respect to specific portions of the construction of the Project and setting forth the amounts actually incurred and paid, or to be incurred, in completing construction of the Project. Such updated Sworn Construction Statement shall be sworn to by the Borrower and the General Contractor to be a true, complete and accurate account of all costs actually incurred and an accurate estimate of all costs to be incurred in the future;

(v) No Defaults. The Borrower is not in default under the terms of the MLA, the Related Documents or any other agreement to which the Borrower is a party and which relates to the construction of the Project;

(vi) Guaranties. Each of the Guarantors shall have executed and delivered to Lender the Guaranties;

(vii) Loan in Balance. The Loan is in balance, as required by the provisions of Section 13(d), above;

(viii) Government Action. No license, permit, permission or authority necessary for the construction of the Project has been revoked or challenged by or before any Governmental Authority;

(g) Suspension of Construction. If the Lender in reasonably good faith determines that any work or materials do not conform to the approved Plans and Specifications or sound building practice, or otherwise departs from any of the requirements of the MLA and this Supplement, the Lender may require the work to be stopped and withhold disbursements until the matter is corrected. In such event, the Borrower will promptly correct the work to the Lender’s satisfaction. Provided Lender’s actions were reasonable, in good faith, and the work or materials did not conform to the approved Plans and Specifications or sound building practice, no such action by the Lender will affect the Borrower’s obligation to complete the Project on or before the Completion Date.

(h) Inspections. The Borrower and the Inspecting Engineer shall be responsible for making inspections of the Project during the course of construction and shall determine to their

own satisfaction that the work done or materials supplied by the Contractors to whom payment is to be made out of each Advance has been properly done or supplied in accordance with the applicable contracts with such Contractors. If any work done or materials supplied by a Contractor are not satisfactory to the Borrower or the Inspecting Engineer, the Borrower will immediately notify the Lender in writing of such fact. It is expressly understood and agreed that the Lender or its authorized representative may conduct such inspections of the Project as it may deem necessary for the protection of the Lender’s interest, and, specifically, an architectural or engineering firm acceptable to the Lender may, at the option of the Lender and at the expense of the Borrower, conduct such periodic inspections of the Project, prepare such written progress reports during the period of construction, prepare such written reports upon completion of the Project and sign such Draw Requests, as the Lender may reasonably request, provided that no inspection shall unreasonably delay progress on the Project. Any inspections which may be made of the Project by the Lender or its representative will be made, and all certificates issued by the Lender’s representative will be issued, solely for the benefit and protection of the Lender, and that Borrower will not rely thereon. The Lender is under no duty to supervise or inspect construction or examine any books and records. Any inspection or examination by the Lender is for the sole purpose of protecting the Lender’s security and preserving the Lender’s rights under the MLA and this Supplement. No default of the Borrower will be waived by any inspection by the Lender. In no event will any inspection by the Lender be a representation that there has been or will be compliance with the Plans or Specifications or that the construction is free from defective materials or workmanship.

(j) No Waiver. Any waiver by the Lender of any condition of disbursement must be expressly made in writing. The making of a disbursement prior to fulfillment of one or more conditions thereof shall not be construed as a waiver of such conditions, and the Lender reserves the right to require their fulfillment prior to making any subsequent disbursements.

14. Construction of Project. As a further condition to the Lender’s funding of Project Costs pursuant to the terms of the MLA and this First Supplement, the Borrower will:

(ii) use the proceeds of all Advances solely to pay the Project Costs as specified in the Project Sources and Uses Statement;

(iii) use its best efforts to require the Contractor(s) to comply with all rules, regulations, ordinances and laws relating to work on the Project;

(iv) obtain the Lender’s prior written approval of any change in the Plans and Specifications for the Project approved by the Lender which might materially adversely affect the value of the Lender’s security, and has a cost of $50,000.00 or greater. The Lender will have a reasonable time to evaluate any requests for its approval of any changes referred to in this paragraph. The Lender may approve or disapprove changes in its discretion,

subject to the foregoing provisions of this Section 14(iv). If it reasonably appears to the Lender that any change may increase the Project Costs, the Lender may require the Borrower to deposit additional funds with the Lender pursuant to the provisions of this The MLA and this in an amount sufficient to cover the increased costs as a condition to giving its approval;

(viii) not purchase any materials, equipment, fixtures, or articles of personal property placed in the Project prior to the Completion Date under any security agreement or other agreement where the seller reserves or purports to reserve title or the right of removal or repossession, or the right to consider them personal property after their incorporation in the work of construction, unless authorized by the Lender in writing;

Borrower will promptly provide a bond, cash deposit, or other security reasonably satisfactory to the Lender to protect the Lender’s interest and security should the contest be unsuccessful;

(xii) maintain in force until full payment of the Loan all insurance required by law, public liability insurance, and property insurance. The policies must be approved by the Lender as to amounts, form, risk coverage, deductibles, insurer, and loss payable and cancellation provision. The Lender’s approval, however, will not be a representation of the solvency of any insurer or the sufficiency of any amount of insurance;

(xiv) pay the Lender’s and the Disbursing Agent’s reasonable out-of-pocket costs and expenses incurred in connection with the making or disbursement of the Loans or in the exercise of any of its rights or remedies under the MLA, this Supplement and the Disbursing Agreement, including but not limited to title insurance and escrow charges, disbursing agent fees, recording charges, and mortgage taxes, reasonable legal fees and disbursements, and reasonable fees and costs for services which are not customarily performed by the Lender’s salaried employees and are not specifically covered by the fees charged to originate the Loan, if any. The provision of this paragraph will survive the termination of the MLA, this Supplement and the repayment of the Loan;

(xvi) comply with the requirements of any commitment or agreement entered into by Borrower with any Governmental Authority to assist the construction or

financing of the Real Property and/or Project and with the terms of all applicable laws, regulations, and requirements governing such assistance;

(xviii) obtain and deliver to the Lender copies of all necessary occupancy certificates relating to the Project.

15. Security. The Borrower’s obligations hereunder and, to the extent related thereto, the MLA, shall be secured as provided in the MLA.

IN WITNESS WHEREOF, the parties have caused this First Supplement to the Master Loan Agreement to be executed by their duly authorized officers as of the date shown above.

(Minneapolis, Minnesota time) on such date or by

(g) Issuer Responsibility. Borrower assumes all risks of the acts or omissions of any beneficiary of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Lender, nor any of its respective officers or directors shall have any responsibility or liability to the Borrower or any other Person for: (a) the failure of any draft to bear any reference or adequate reference to any Letter of Credit, or the failure of any documents to accompany any draft at negotiation, or the failure of any Person to surrender or to take up any Letter of Credit or to send documents apart from drafts as required by the terms of any Letter of Credit, or the failure of any Person to note the amount of any instrument on any Letter of Credit, each of which requirements, if contained in any Letter of Credit itself, it is agreed may be waived by the Lender; (b) errors, omissions, interruptions, or delays in transmission or delivery of any messages; (c) the validity, sufficiency, or genuineness of any draft or other document, or any endorsement(s) thereon, even if any such draft, document or endorsement should in fact prove to be in any and all respects invalid, insufficient, fraudulent, or forged or any statement therein is untrue or inaccurate in any respect; (d) the payment by the Lender to the beneficiary of any Letter of Credit against presentation of any draft or other document that does not comply with the terms of the Letter of Credit; or (e) any other circumstance whatsoever in making or failing to make any payment under a Letter of Credit.

their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

8. Interest Rate. Subject to the provisions of Sections 6 and 9 of this Second Supplement, the Revolving Loan shall bear interest at a rate equal to the LIBOR Rate plus 325 basis points. The computation of interest, amortization, maturity and other terms and conditions of the Revolving Loan shall be as provided in the Revolving Note, provided, however, in no event shall the applicable rate exceed the maximum nonusurious interest rate, if any, that at any time, or from time to time, may be contracted for, taken, reserved, charged, or received under applicable state or federal laws (the “Maximum Rate”).

9. Default Interest. In addition to the rights and remedies set forth in the MLA: (i) if the Borrower fails to make any payment to Lender when due (including, without limitation, any purchase of equity of Lender when required), then at Lender’s option in each instance, such obligation or payment shall bear interest from the date due to the date paid at 2% per annum in excess of the rate of interest that would otherwise be applicable to such obligation or payment; (ii) upon the occurrence and during the continuance of an Event of Default beyond any applicable cure period, if any, at Lender’s option in each instance, the unpaid balances of the Revolving Loan shall bear interest from the date of the Event of Default or such later date as Lender shall elect at 2% per annum in excess of the rate(s) of interest that would otherwise be in effect on the Revolving Loan under the terms of the Revolving Note; (iii) after the maturity of the Revolving Loan, whether by reason of acceleration or otherwise, the unpaid principal balance of the Revolving Loan (including without limitation, principal, interest, fees and expenses) shall automatically bear interest at 2% per annum in excess of the rate of interest that would otherwise be in effect on the Revolving Loan under the terms of the Revolving Note. Interest payable at the Default Rate shall be payable from time to time on demand or, if not sooner demanded, on the last day of each calendar month.

10. Late Charge. If any payment of principal or interest due under this Supplement or the Revolving Note is not paid within ten (10) days of the due date thereof, the Borrower shall, in addition to such amount, a late charge equal to five percent (5%) of the amount of such payment.

11. Changes in Law Rendering Certain LIBOR Rate Loans Unlawful. In the event that any change in any applicable law (including the adoption of any new applicable law) or any change in the interpretation of any applicable law by any judicial, governmental or other regulatory body charged with the interpretation, implementation or administration thereof, should make it (or in the good-faith judgment of the Lender should raise a substantial question as to whether it is) unlawful for the Lender to make, maintain or fund LIBOR Rate Loans, then:

(a) the Lender shall promptly notify each of the other parties hereto; and (b) the obligation of the Lender to make LIBOR rate loans of such type shall, upon the effectiveness of such event, be suspended for the duration of such unlawfulness. During the period of any suspension, Lender shall make loans to Borrower that are deemed lawful and that as closely as possible reflect the terms of the MLA.

12. Payments and Computations.

(b) Application of Funds. Apply all payments received by it to the Borrower’s obligations to Lender in such order and manner as Lender may elect in its sole discretion; provided that any payments received from any guarantor or from any disposition of any collateral provided by such guarantor shall only be applied against obligations guaranteed by such guarantor.

(d) Proceeds of Collateral. All proceeds received by the Lender from the sale or other liquidation of the Collateral when an Event of Default exists shall first be applied as payment of the accrued and unpaid fees and expenses of the Lender hereunder and then to all other unpaid or unreimbursed Loan Obligations (including reasonable attorneys’ fees and expenses) owing to the Lender and then any remaining amount of such proceeds shall be applied to the unpaid amounts of Loan Obligations, until all the Loan Obligations have been paid and satisfied in full or cash collateralized. After all the Loan Obligations (including without limitation, all contingent Loan Obligations) have been paid and satisfied in full, all Commitments terminated and all other obligations of the Lender to the Borrower otherwise satisfied, any proceeds of Collateral shall be delivered to the Person entitled thereto as directed by the Borrower or as otherwise determined by applicable law or applicable court order.

(e) Computations. Except as expressly provided otherwise herein, all computations of interest and fees shall be made on the basis of actual number of days lapsed over

a year of 365 or 366 days, as appropriate. Interest shall accrue from and include the date of borrowing, but exclude the date of payment.

13. Maximum Amount Limitation. Anything in this MLA, this Second Supplement, or the other Loan Documents to the contrary notwithstanding, Borrower shall not be required to pay unearned interest on the Revolving Note or any of the Loan Obligations, or ever be required to pay interest on the Revolving Note or any of the Loan Obligations at a rate in excess of the Maximum Rate, if any. If the effective rate of interest which would otherwise be payable under the MLA, this Supplement, the Revolving Note, or any of the other Loan Documents would exceed the Maximum Rate, if any, then the rate of interest which would otherwise be contracted for, charged, or received under the MLA, this Supplement, the Revolving Note, or any of the other Loan Documents shall be reduced to the Maximum Rate, if any. If any unearned interest or discount or property that is deemed to constitute interest (including, without limitation, to the extent that any of the fees payable by Borrower for the Loan Obligations to the Lender under the MLA, this Supplement, the Revolving Note, or any of the other Loan Documents are deemed to constitute interest) is contracted for, charged, or received in excess of the Maximum Rate, if any, then such interest in excess of the Maximum Rate shall be deemed a mistake and canceled, shall not be collected or collectible, and if paid nonetheless, shall, at the option of the holder of the Revolving Note, be either refunded to the Borrower, or credited on the principal of the Revolving Note. It is further agreed that, without limitation of the foregoing and to the extent permitted by applicable law, all calculations of the rate of interest or discount contracted for, charged or received by the Lender under the Revolving Note, or under any of the Loan Documents, that are made for the purpose of determining whether such rate exceeds the Maximum Rate applicable to the Lender, if any, shall be made, to the extent permitted by applicable laws (now or hereafter enacted), by amortizing, prorating and spreading during the period of the full terms of the Advances evidenced by the Revolving Note, and any renewals thereof all interest at any time contracted for, charged or received by Lender in connection therewith. This section shall control every other provision of all agreements among the parties to the MLA pertaining to the transactions contemplated by or contained in the Loan Documents, and the terms of this section shall be deemed to be incorporated in every Loan Document and communication related thereto.

14. Lender Records. All advances and all payments or prepayments made thereunder on account of principal or interest may be evidenced by the Lender in accordance with its usual practice in an account or accounts evidencing such advances and all payments or prepayments thereunder from time to time and the amounts of principal and interest payable and paid from time to time thereunder; in any legal action or proceeding in respect of the Notes, the entries made in such account or accounts shall be prima facie evidence of the existence and amounts of all advances and all payments or prepayments made thereunder on account of principal or interest. Lender shall provide monthly statements of such entries to Borrower for the purpose of confirming the accuracy of such entries.

15. Mandatory Prepayments or Collateralization. The Borrowers shall, within five (5) days following the earlier of the delivery of each Borrowing Base Certificate hereof or the day upon which such Borrowing Base Certificate was due, either (i) prepay the Advances in the amount, if any, by which the Outstanding Credit on the date of prepayment under this Section 15

exceeds the Borrowing Base at such time, together with accrued interest to the date of such prepayment on the amount prepaid, or (ii) pledge and assign to the Lender additional collateral acceptable to the Lender, in the Lender’s sole discretion, and deliver all documentation that the Lender, in its sole discretion, may require in connection with such pledge and assignment and the perfection of a first-priority security interest in such additional collateral, so that the Borrowing Base plus the value assigned by the Lender, in its sole discretion, to such additional collateral equals or exceeds the Outstanding Credit.

16. Loan Payments. During the continuance of an Event of Default, the Lender may deduct any obligations due or any other amounts due and payable by the Borrower under the Loan Documents from any accounts maintained with the Lender.

17. Reporting Requirements. In addition to the reporting requirements under Section 5.01(c) in the MLA, the Borrower will furnish to the Lender as soon as available and in any event within 30 days after the end of each month (or at such other times or with such greater frequency as is requested by the Lender), a duly completed Borrowing Base Certificate, setting forth the Borrowing Base as of the last day of such month calculated based upon collateral value criteria and advance rates which do not exceed those set forth in the Borrowing Base Certificate, and including such other information, representation and warranties contemplated therein, certified by the appropriate authorized officer of the Borrower.

18. Compensation. Upon the request of the Lender, the Borrower shall pay to the Lender such amount or amounts as shall be sufficient (in the reasonable opinion of the Lender) to compensate it for any loss, cost, or expense (excluding loss of anticipated profits incurred by it) as a result of: (i) any payment, prepayment, or conversion of a LIBOR rate loan for any reason on a date other than the last day of the Interest Period for such Loan; or (ii) any failure by the Borrower for any reason (including, without limitation, the failure of any condition precedent specified in the MLA or this Supplement to be satisfied) to borrow, extend, or prepay a LIBOR rate loan on the date for such borrowing, extension, or prepayment specified in the relevant notice of borrowing, extension or prepayment under this Agreement.

Such indemnification may include any amount equal to the excess, if any, of: (a) the amount of interest which would have accrued on the amount so prepaid, or not so borrowed, converted or extended, for the period from the date of such prepayment or of such failure to borrower, convert or extend to the last day of the applicable Interest Period (or in the case of a failure to borrow, convert or extend, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such loan as provided for herein; over (b) the amount of interest (as reasonably determined by the Lender) which would have accrued to the Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank LIBOR market. The covenants of the Borrower set forth in this section shall survive the repayment of the Revolving Loan and other obligations under the Loan Documents hereunder.

19. Security. The Borrower’s obligations hereunder and, to the extent related thereto, the MLA, shall be secured as provided in the MLA.
