ARTICLE II

AMOUNTS AND TERMS OF THE LOANS

Section 2.01. Loans. Subject to the terms and conditions of this Agreement and in reliance upon the representations and warranties set forth in this Agreement, the Lender has agreed to lend to Borrower the following amounts, for the purposes as further described below:

(b) Term Revolving Loan. Lender agree to lend to the Borrower, on the Closing Date, and from time to time thereafter on a revolving basis, an amount not to exceed $8,008,689.00, pursuant to the terms and conditions set forth in Section 2.03 and the Term Revolving Note.

Section 2.02. Term Loan.

(a) Term Loan. Lender agrees to lend to the Borrower and the Borrower agrees to borrow from the Lender a Term Loan in the amount of Forty Million and No/100 Dollars ($40,000,000.00) pursuant to the terms and conditions set forth in this Section 2.02 and the Term Note. The Term Loan shall be comprised of two tranches of Twenty Million and No/100 Dollars ($20,000,000.00) each, with the first tranche bearing interest at the variable rate set forth in Section 2.02(c)(i), and the second tranche bearing interest at the rate set forth in Section 2.02(c)(ii).

(b) Term Loan Term. The Term Loan term shall run for a period beginning on the Closing Date and ending on the Term Loan Maturity Date.

(i) Variable Rate. Subject to the provisions of Sections 2.04 and 2.09, Twenty Million and no/100 dollars ($20,000,000.00) of the Term Loan shall bear interest at a rate per annum equal to the greater of (A) LIBOR Rate plus three hundred fifty (350) basis points or (B) five percent (5.0%). The rate of interest due thereon shall initially be determined as of the Closing Date and shall thereafter be adjusted as and when LIBOR Rate changes. All such adjustments to the rate of interest shall be made and become effective as of the first day of the month following the date of any change in LIBOR Rate and shall remain in effect until and including the day immediately preceding the next such adjustment (each such day hereinafter being referred to as an “Adjustment Date”). All such adjustments to the rate of interest shall be made and become effective as of the first Adjustment Date following such change in the LIBOR Rate. All such adjustments to said rate shall be made and become effective as of the Adjustment Date, and said rate as adjusted shall remain in effect until and including the day immediately preceding the next Adjustment Date. Interest shall be computed on the basis of a year of three hundred sixty five (365) days, but charged for actual days principal is outstanding.

(ii) Fixed Rate. Subject to the provisions of Sections 2.04 and 2.09, Twenty Million and no/100 dollars ($20,000,000.00) of the Term Loan shall bear interest from the Closing Date and until the third (3rd) anniversary of the Closing Date at a fixed rate equal to five and three-quarters percent (5.75%) per annum. On the third (3rd) anniversary of the Closing Date, such interest rate will be adjusted, and on dates occurring at successive intervals of three years each thereafter during the remaining term of the Term Loan. The adjusted interest rate will be calculated by adding 225 basis points to the then current index. The index for adjustments is the Lender’s cost of funds for three-year adjustable rate products. Lender’s cost of funds is the rate determined by the Lender to represent the Lender’s direct and indirect cost of acquiring funds with a term equal to the applicable interest period and interest rate product selected by the Borrower. Interest shall be computed on the basis of a year of three hundred sixty five (365) days, but charged for actual days principal is outstanding.

(d) Term Loan Payments. Beginning on first Monthly Payment Date following the Closing Date and on each Monthly Payment Date thereafter until the Term Loan Maturity Date, the Borrower shall make equal monthly payments of principal and accrued interest in such amounts as will be required to fully amortize the entire outstanding principal of the Term Loan, over a period not to exceed ten (10) years from the Closing Date. The amount of said monthly payments shall be recalculated and, if necessary, adjusted to account for changes in the effective rate of interest hereunder and to maintain said ten (10) year amortization. The entire unpaid principal balance and accrued and unpaid interest on the Term Loan is due and payable in full on the Term Loan Maturity Date.

(e) Excess Cash Flow Sweep. In addition to all other payments of principal and interest required hereunder and under the Term Note, the Borrower shall remit to Lender, beginning with the first fiscal year end following the Closing Date and continuing throughout the term of the Term Loan, an amount equal to 25% of the Borrower’s Excess Cash Flow for the immediately preceding fiscal year (the “Excess Cash Flow Payment”), which shall be calculated based upon the immediately preceding fiscal year end audited financial statements of the Borrower, on or before 90 days after the end of each fiscal year, and which shall be paid on or before 120 days after the end of the fiscal year for which the payment is calculated. Total Excess Cash Flow Payments required hereunder shall not exceed Two Million and No/100 Dollars ($2,000,000.00) for any fiscal year. All Excess Cash Flow Payments shall be applied to the reduction of the outstanding principal balance of the Term Loan. No Excess Cash Flow Payments shall be required for a fiscal year where Borrower’s Owner’s Equity Ratio is greater than 50% as calculated at the end of the fiscal year for which the Excess Cash Flow Payment is being calculated.

(f) 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 otherwise provided in this Agreement. Any prepayment does not otherwise affect Borrower’s obligations to pay any fees due hereunder. The Term Loan is subject to mandatory prepayment, at the option of the Lender, as set forth herein.

Section 2.03. Term Revolving Loan.

(a) Term Revolving Loan. On the terms and conditions set forth herein, Lender agrees to make one or more advances to the Borrower, during the period beginning on the Closing Date and ending on the Business Day immediately preceding the Term Revolving Loan Maturity Date (the “Term Revolving Loan Termination Date”), in an aggregate principal amount outstanding at any one time not to exceed Term Revolving Loan Commitment. The Term Revolving Loan Commitment shall expire at 12:00 noon Central time on the Term Revolving Loan Maturity Date. Term Revolving Loan amounts borrowed and repaid or prepaid may be reborrowed at any time prior to and including the Term

Revolving Loan Termination Date provided, however, that at no time shall the sum of the Outstanding Revolving Advances exceed the Term Revolving Loan Commitment. The Borrower shall, without penalty or premium and within five (5) days following each anniversary date of the Closing Date, prepay the Outstanding Revolving Advances in the amount, if any, by which the Outstanding Credit on such date exceeds the Term Revolving Loan Commitment then in effect, together with accrued interest thereon to the date of such prepayment.

(b) Purpose. Revolving Advances under the Term Revolving Loan may be used for working capital, cash and inventory management purposes of the Borrower, including closing costs and fees associated with the Term Revolving Loan. In addition to the foregoing, Borrower may use the proceeds of one or more Revolving Advances for Pipeline Project work being completed on the Real Property, for the Shaw Remediation Project, to convert the Project to natural gas power, to make capital expenditure relating to the corn oil separation/extraction system equipment or installation thereof, and to make equity investments in, and to acquire all of the limited liability company membership interest in HLBE — PC (the “HLBE — PC Investment”). The Borrower agrees that the proceeds of the Term Revolving Loan are to be used only for the purposes set forth in this Section 2.03(b).

(d) Interest Rate. Subject to the provisions of Sections 2.04 and 2.09, the Term Revolving Loan shall bear interest at a rate per annum equal to the greater of (A) LIBOR Rate plus three hundred fifty (350) basis points or (B) five percent (5.0%). The rate of interest due thereon shall initially be determined as of the Closing Date and shall thereafter be adjusted as and when LIBOR Rate changes. All such adjustments to the rate of interest shall be made and become effective as of the first day of the month following the date of any change in LIBOR Rate and shall remain in effect until and including the day immediately preceding the next such adjustment (each such day hereinafter being referred to as an “Adjustment Date”). All such adjustments to the rate of interest shall be made and become effective as of the first Adjustment Date following such change in the LIBOR Rate. All such adjustments to said rate shall be made and become effective as of the Adjustment Date, and said rate as adjusted shall remain in effect until and including the day immediately preceding the next Adjustment Date. Interest shall be computed on the basis of a year of three hundred sixty five (365) days, but charged for actual days principal is outstanding.

(e) Repayment of the Term Revolving Loan. The Borrower will pay interest on the Term Revolving Loan on the first (1st) day of each month, commencing on the first (1st) Monthly Payment Date following the date on which the first Advance is made on the Term Revolving Loan, and continuing on each Monthly Payment Date thereafter until the Term Revolving Loan Maturity Date. On the Term Revolving Loan Maturity Date, the amount of the then unpaid principal balance of the Term Revolving Loan and any and all other amounts due and owing hereunder or under any other Loan Document relating to the Term Revolving Loan shall be due and payable. If any 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.

(iv) Unused Commitment Fee. In addition to the fees payable hereunder, Borrower agrees to pay to the Lender an Unused Commitment Fee on the average daily unused portion of such Lender’s commitment under the Term Revolving Loan at the rate of 0.35% per annum, payable in arrears in quarterly installments payable on the first (1st) day of each calendar quarter during the term of the Term Revolving Loan.

(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.

(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 2.09. Maximum Amount Limitation. Anything in this Agreement, 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 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 2.09 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 2.09 shall be deemed to be incorporated in every Loan Document and communication related thereto.

Section 2.10. 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 2.11. 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 2.12. 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, 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 2.13. 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 2.13 shall survive the repayment of the Loans and other obligations under the Loan Documents hereunder.

Section 2.14. Funds Held Program. Lender, in its sole discretion, may offer a funds held program (the “Program”) to permit the Borrower to make advance conditional payments on designated loans, on such terms and conditions as the Lender may establish from time to time. Lender reserves the right, in its discretion, to amend or terminate the Program at any time upon notice to Borrower. The following terms and conditions apply to all Program accounts in connection with loans from Lender:

(a) Advance Payments. Subject to Lender’s rights to direct the application of payments, an advance payment made to be applied to any amounts due and owing to the Lender on the Loan Obligations in the future, or used for any other purpose allowed by the Program, will be in a designated Program account as of the date received. If a special prepayment of principal is desired, Borrower must so specify when an advance payment is made.

(b) Program Interest. Interest will accrue on funds in the Program account at such times and at such rates determined by Lender. Lender may change the interest rate or accrual period from time to time without notice. The Program may provide for different interest rates for different categories of loans.

(c) Application of Funds. Funds in the Program account for a designated loan will be automatically applied by Lender on the Quarterly Payment Date toward payment of the installment or related charges when the loan installment or other related charge becomes due. Any accrued interest in the Program account will be applied first to the installment or related charges. If the funds in the Program account are insufficient to pay the entire installment or related charges, Borrower shall pay the difference by the Quarterly Payment Date. Funds received after a loan installment or related charges have been billed will be applied to the installment or related charges due. Funds received in excess of the billed installment amount or related charges will be placed in the Program account unless otherwise designated as a special principal payment by Borrower or designated for another purpose allowed by the Program.

(d) Withdrawal of Funds. Lender may, in its sole discretion, permit Borrower to withdraw funds from the Program account in accordance with Lender’s Program.

(e) Limitations. Lender, in its sole discretion, may restrict the availability of any funds in the Borrower’s Program account.

(f) Lender Options. The Lender may, in its sole discretion, apply funds from the Program account without notice to Borrowers for the following reasons:

(i) Protective Advance. If the Borrower fails to pay when due any amounts Borrower is required to pay pursuant to the Loan Documents, Lender may apply funds in the Program account to pay such amounts.

(ii) Account Ceiling. If at any time the Program account balance exceeds the unpaid balance on the designated loan, Lender may apply the funds in the Program account to pay off the loan. Any excess funds will be returned to Borrower.

(iii) Transfer of Security. If Borrower sells, assigns, or transfers any interest in any collateral for the loan, Lender may apply the funds in the Program account to the remaining loan balance.

(iv) Termination. In the event the Lender, in its sole discretion, terminates the Program, Lender may apply all funds in the Program account to the remaining loan balance effective on the termination date.

(g) No Program Account Insurance. Neither the advance payments nor the accrued interest in a Program account are insured by a governmental agency or instrumentality.

(h) Liquidation of Lender. If Lender is placed in liquidation, Borrower shall be sent by the receiver such notices as required by the Farm Credit Administration regulations then in effect. Such regulations currently provide for advance notice from the receiver that funds in the Program account will be applied to the loan and that funds in the Program account will not earn interest after the receiver is appointed.

Section 2.15. Underwriting/Participation/Facility Fees. The Borrower has paid to the Lender the Underwriting Fee of $120,000.00 and all other costs, expenses, fees, etc. required hereunder, including those provided for in Section 7.04.

(b) may 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 and its Subsidiaries, obtain the appointment of a receiver to take possession of all Collateral of the Borrower and its Subsidiaries, including, but not limited to all Personal Property, including all fixtures and equipment leased, occupied or used by any of the Borrower and its Subsidiaries.

(d) in its discretion, enter the Real Property and take any and all actions necessary in its judgment to complete construction of the Project or the Pipeline Project, including but not limited to making changes in plans and specifications therefore, 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 or the Pipeline Project, it will not assume any liability to the Borrower or any other person therefore or for the manner or quality of construction thereof, 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 and/or the Pipeline 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 or the Pipeline 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 or the Pipeline 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 rights to notify or instruct any Commodity Intermediary under any Commodity Account Control Agreement or Bank under any Deposit Account Control Agreement;

(g) may apply any funds held by Lender in a Program Account toward the outstanding Loan Obligations of the Borrower; and

(h) may exercise any 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.

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 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 after an Event of Default, 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 and each of its Subsidiaries 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.

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.

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.
