If the Agent at any time reasonably determines that the amount of the undisbursed Construction Loan proceeds and the unfunded Borrower’s Equity will not be sufficient to fully pay for all costs required to complete the construction of the Project in accordance with the Construction Documents, 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 Construction Documents or to any other cause, the Agent may make written demand on the Borrower to deposit in an escrow fund to be established with the Agent an amount equal to the amount of the shortage reasonably determined by the Agent. The Borrower shall then deposit or cause to be deposited the required funds, which deposit can be funded through, among other sources, proceeds of loans permitted pursuant to Sections 5.02(e)(viii) or 5.02(e)(xi), with the Agent within ten (10) days after the date of the Agent’s written demand.

          (h) [Reserved]

          (i) Suspension of Construction. If the Agent in reasonably good faith determines that any work or materials do not materially conform to the Construction Documents, the Agent 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 Agent’s reasonable satisfaction. Provided Agent’s actions were reasonable, in good faith, and the work or materials did not materially conform to the Construction Documents , no such action by the Agent or the Banks will affect the Borrower’s obligation to complete the Project on or before the Substantial Completion Date.

          (j) 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 directly out of each Construction Advance has been properly done or supplied in accordance with the applicable contracts with such Contractors. If any material work done or materials supplied by a Contractor are not satisfactory to the Borrower, the Borrower will promptly notify the Agent in writing of such fact. It is expressly understood and agreed that the Agent or its authorized representative may conduct such inspections of the Project as it may deem necessary for the protection of the Agent’s or the Banks’ interest, upon reasonable prior notice and at reasonable times and, specifically, an architectural or engineering firm acceptable to the Agent may, at the option of the Agent and at the expense of the Borrower, conduct such periodic inspections of the Project and prepare such written progress reports during the period of construction, as the Agent may reasonably request, provided that no inspection shall unreasonably delay progress on or interfere with the Project or the Borrower’s use of the Real Property. Any inspections which may be made of the Project by the Agent or its representative will be made, and all certificates issued by the Agent’s representative will be issued, solely for the benefit and protection of the Agent and the Banks, and the Borrower will not rely thereon. The Agent is under no duty to supervise or inspect construction or examine any books and records. Any inspection or examination by the Agent is for the sole purpose of protecting the Agent’s and the Banks’ security and preserving the Agent’s and the Banks’ rights under this Agreement. No default of the Borrower will be waived by any inspection by the Agent. In no event will any inspection by the Agent 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.

          (k) Banks’ Application of Loan Proceeds. Notwithstanding the provisions of Section 2.02(d), the Agent may elect, upon ten (10) days’ prior written notice to the Borrower, to use the Construction Loan funds to pay, as and when due, any Construction Loan fees owing to the Banks, interest on the Construction Loan, release charges under prior mortgages on the Property, and legal fees and disbursements of the Agent’s attorneys which are payable by the Borrower, unless the Borrower causes such amount(s) to be paid within said ten (10) days. Such payments may be made, at the option of the Agent, by debiting or charging the Construction Loan funds in the amount of such payments.

          (l) Cost Information. All Advances under the Construction Loan will be based upon the Project Costs as set forth in the Certified Construction Statement. In the event that the Borrower becomes aware of any change in the approved Project Costs, which would increase the total Project Cost in excess of Fifty Thousand and No/100 Dollars ($50,000.00) above the amount shown on the Certified Construction

Statement, the Borrower shall immediately notify the Agent in writing and promptly submit to the Agent for its approval a revised Certified Construction Statement. No further disbursements need be made by the Agent unless and until the revised Certified Construction Statement is approved by the Agent. The Agent reserves the right to approve or disapprove any revised Certified Construction Statement in its reasonable discretion if any such increase in total Project Costs is in excess of $50,000.

          (m) No Waiver. Any waiver by the Agent of any condition of disbursement must be expressly made in writing.

No consent of any Bank (other than any Bank making loans or whose commitment is increased under the Additional Revolving Line of Credit Facility) is required to permit the Loans contemplated by this Section 2.05(m) or to permit the aforesaid amendment to effectuate the Additional Revolving Line of Credit Facility. This Section 5.01(m) shall supersede any provisions contained in this Agreement, including, without limitation, Section 8.01, to the contrary.

     Section 2.06. Swingline Loan.

          (a) Swingline Loan. Subject to the terms and conditions of this Agreement, the Swingline Bank agrees to make one or more Advances to the Borrower from time to time, from and including the Conversion Date to, but excluding, the Term Revolving Loan Termination Date and the Revolving Line of Credit Termination Date, in an aggregate principal amount at any time outstanding up to but not exceeding the Swingline Commitment; provided, however that after calculation of the participation interests of each Bank in such Advances:

               (i) the aggregate amount of outstanding Swingline Advances shall not at any time exceed the amount of One Million and No/100 Dollars ($1,000,000.00) (the “Swingline Commitment”);

               (ii) the Outstanding Credit with respect to the Revolving Line of Credit applicable to a Bank shall not at any time exceed the lesser of (A) such Bank’s Pro Rata Share of the Borrowing Base, or (B) such Bank’s Revolving Line of Credit Commitment; and

               (iii) the Outstanding Credit with respect to the Revolving Line of Credit shall not at any time exceed the lesser of (A) the Borrowing Base or (B) the aggregate amount of the Revolving Commitments at such time.

Subject to the foregoing limitations, and the other terms and provisions of this Agreement, the Borrower may borrow, prepay, and reborrow Swingline Loans hereunder up to the amount of the Swingline Commitment. The Swingline Bank may, by written notice given to the Agent not later than 10:00 A.M. (Minneapolis, Minnesota time) on any Business Day, require the Banks to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which the Banks will participate. Promptly upon receipt of such notice, the Agent will give notice thereof to each Bank specifying in such notice such Bank’s Pro Rata Share of such Swingline Loan or Loans. Each Bank hereby absolutely and unconditionally agrees upon receipt of notice as provided in this Section 2.06 to pay to the Agent for the account of the Swingline Bank such Bank’s Pro Rata Share of such Swingline Loan or Loans. Each Bank acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of an Event of Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Bank shall comply with its obligation under this Subsection by wire transfer of immediately available funds, in the same manner as provided in Section 2.21 with respect to Loans made by such Bank (and Section 2.22 shall apply to the payment obligations of the Banks), and the Agent shall promptly pay to the Swingline Bank the amounts so received by it from the Banks. The Agent shall notify the Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to the Agent and not to the Swingline Bank. Any amounts received by the Swingline Bank from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by the Swingline Bank of the proceeds of a sale of participations therein shall be promptly remitted to the Agent; any such amounts received by the Agent shall be promptly remitted by the Agent to the Banks that shall have made their payments pursuant to this Subsection and to the Swingline Bank, as their interests may appear. The purchase of participations in a Swingline Loan pursuant to this Subsection shall not relieve the Borrower of any default in the payment thereof. Notwithstanding the foregoing, a Bank shall not have any obligation to acquire a participation in a Swingline Loan pursuant to this Subsection if an Event of Default shall have occurred and be continuing at the time such Swingline Loan was made and such Bank shall have notified the Swingline Bank in writing, at least one Business Day prior to the time such Swingline Loan was made, that such Event of Default has occurred and that such Bank will not acquire participations in Swingline Loans made while such Event of Default is continuing.

          (b) Swingline Advances. Each Swingline Advance shall be made, to the extent that the Swingline Bank is so obligated under Section 2.05(a), on a Request for Advance from the Borrower to the Agent delivered before 12:00 P.M. (Minneapolis, Minnesota time) on the date of such Swingline Advance, specifying the amount of such Swingline Advance. Any Request for Advance applicable to a Swingline Advance received after 12:00 P.M. (Minneapolis, Minnesota time) shall be deemed to have been received and be effective on the next Business Day. The amount of each Swingline Advance made hereunder shall, subject to the terms and conditions of this Agreement, be made available to the Borrower by (i) depositing the same, in same day funds, in an account of the Borrower or (ii) wire transferring such funds to a Person or Persons designated by the Borrower in writing.

          (c) Minimum Amounts. Each Swingline Advance shall be in a minimum amount equal to Fifty Thousand and No/100 Dollars ($50,000.00).

          (d) Repayment of Swingline Loan. The Borrower shall pay to the Agent for the account of the Swingline Bank the outstanding principal amount of each Swingline Advance on the earlier of (i) the Term Revolving Loan Termination Date, (ii) the Revolving Line of Credit Termination Date, or (iii) the date which is thirty (30) days after the Swingline Advance is made (the earliest of such date with

respect to a Swingline Advance herein the “Swingline Maturity”). Subject to the other terms and conditions of this Agreement, the Borrower may repay a Swingline Advance on its Swingline Maturity or at any time prior thereto by requesting a Revolving Advance in accordance with Sections 2.04(e) or 2.05(e) with the proceeds thereof payable to the Swingline Bank for its own account or by using cash on hand. The Swingline Bank, at any time in its sole and absolute discretion and whether or not a Swingline Maturity shall have occurred, may require that each other Bank fund its participation in the then outstanding principal amount of all Swingline Advances by giving each other Bank notice thereof as set forth herein above. Additionally, if the Borrower shall not have repaid a Swingline Advance by 12:00 P.M. (Minneapolis, Minnesota time) on the corresponding Swingline Maturity, the Swingline Bank will notify each Bank of the aggregate principal amount of the Swingline Advance which has not been repaid. Upon the giving of any notice by the Swingline Bank under either of the preceding two sentences, each such Bank shall make available to the Swingline Bank, in immediately available funds, an amount equal to its Pro Rata Share of the aggregate principal amount of the Swingline Advance or Swingline Advances subject to such notice by not later than 3:00 P.M. (Minneapolis, Minnesota time) on the date such notice is received if such notice is received by 12:00 P.M., or by 11:00 A.M. (Minneapolis, Minnesota time) on the next Business Day if such notice is received after 12:00 P.M. (Minneapolis, Minnesota time), whether or not the conditions to an Advance under Article III are satisfied.

          (e) Swingline Interest Rate. The Swingline Loan shall bear interest at a rate equal to the LIBOR Rate plus two hundred ninety (290) basis points. The rate of interest due hereunder shall initially be determined as of the date of each Swingline Advance and shall thereafter be initially adjusted on the first day of the immediately succeeding calendar month. All such adjustments to the rate of interest shall be made and become effective as of the first Adjustment Date following each Swingline Advance. All such adjustments to said rate shall be made and become effective as of each subsequent Adjustment Date, and said rate as adjusted shall remain in effect until and including the day immediately preceding the next Adjustment Date. Interest hereunder shall be computed on the basis of a year of three hundred sixty five (365) days, but charged for actual days principal is outstanding. In no event shall the applicable rate exceed the Maximum Rate.

     Section 2.07. Evidence of Debt. The extension of credit made by each Bank shall be evidenced by one or more accounts or records maintained by such Bank and by the Agent in the ordinary course of business. The accounts or records maintained by the Agent and each Bank shall be prima facie evidence of the amount of the credit extensions made by the Banks to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Bank and the accounts and records of the Agent in respect of such matters, the accounts and records of the Agent shall control in the absence of manifest error. Upon the request of any Bank made through the Agent, the Borrower shall execute and deliver to such Bank (through the Agent) a promissory note in the form attached as Exhibits E, G, or H which shall evidence such Bank’s loans in addition to such accounts or records. Each Bank may attach schedules to its Note and endorse thereon the date, amount and maturity of its loans and payments with respect thereto. Upon the termination of the Commitments and repayment of all Obligations hereunder, each Bank shall, at the request of the Borrower (and at the Borrower’s expense), return to the Borrower the Note or Notes evidencing such Bank’s loans marked “cancelled.”

     Section 2.08. Letters of Credit. All Letters of Credit that are issued under this Agreement are subject to the following:

          (a) Letter of Credit Request Procedure. The Borrower shall give the Agent and the Issuer irrevocable prior notice (effective upon receipt)

on or before 12:00 P.M. (Minneapolis, Minnesota time) on a Business Day which is at least three (3) Business Days (or such shorter period as may be agreed by the Issuer) prior to the date of the requested issuance of a Letter of Credit specifying the requested amount, the beneficiary of each Letter of Credit to be issued, the expiry date and issuance date of each Letter of Credit to be issued, and the nature of the transactions to be supported thereby. Any such notice received after 12:00 P.M. (Minneapolis, Minnesota time) on a Business Day shall be deemed to have been received and be effective on the next Business Day. Upon receipt of such notice, the Agent shall promptly notify each Bank of the face amount and expiry date of such Letter of Credit and of such Bank’s Pro Rata Share of the amount of the proposed Letter of Credit. The Issuer shall provide a Bank a copy of each Letter of Credit it has issued hereunder upon such Bank’s request. Each Letter of Credit shall be substantially in the form of Exhibit I, or otherwise shall be satisfactory in form and substance to the Agent, the Borrower, and the Issuer, shall be payable in U.S. dollars, and shall be issued pursuant to such documentation as the Issuer may require, including the Issuer’s standard form letter of credit request and reimbursement agreement; provided that, in the event of any conflict between the terms of such credit request and reimbursement agreement and the other Loan Documents, the terms of the other Loan Documents shall control.

          (b) Banks’ Pro Rata Shares. Upon the date of issue of a Letter of Credit, the Issuer shall be deemed, without further action by any party hereto, to have sold to each other Bank, and each other Bank shall be deemed, without further action by any party hereto, to have purchased from the Issuer a participation to the extent of such Bank’s Pro Rata Share in such Letter of Credit and the related Letter of Credit Liabilities.

          (c) Letter of Credit Fees. The Borrower shall pay to the Agent for the account of each Bank an irrevocable letter of credit fee on each such Bank’s Pro Rata Share of the maximum amount available for drawings under each Letter of Credit, such letter of credit fee (i) to be in an amount equal to one hundred fifty (150) basis points, on an annualized basis, of the maximum amount available to be drawn under such Letter of Credit on the date of calculation of such fee, and (ii) to be paid on the date of issuance of such Letter of Credit and on each anniversary date of the date of issuance of such Letter of Credit for so long as such letter of Credit remains outstanding. After receiving any payment of any letter of credit fees under this Subsection (c), the Agent will promptly pay to each Bank the letter of credit fees then due such Bank. With respect to each Letter of Credit, the Borrower shall also pay to the Issuer for its account only all reasonable fees, costs, and expenses of the Issuer arising in connection with any Letter of Credit, including the Issuer’s customary fees for amendments, transfers, and drawings on Letters of Credit.

          (d) Reimbursements. After receipt of the notice delivered pursuant to Section 2.21 with respect to a Letter of Credit, the Borrower shall be irrevocably and unconditionally obligated to reimburse the Banks for any amounts paid by the Banks upon any demand for payment or drawing under the applicable Letter of Credit, without presentment, demand, protest, or other formalities of any kind other than the notice required by Section 2.21. Such reimbursement shall occur no later than 3:00 P.M. (Minneapolis, Minnesota time) three (3) Business Days after the date of payment under the applicable Letter of Credit if the notice under Section 2.21 is received by 12:00 P.M. (Minneapolis, Minnesota time) on such date or by 11:00 A.M. (Minneapolis, Minnesota time) four (4) Business Days after the date of such payment, if such notice is received after 12:00 P.M. (Minneapolis, Minnesota time). All payments made pursuant to Section 2.05(j) with proceeds of Revolving Loans made pursuant thereto shall constitute satisfaction of the Borrower’s reimbursement obligation hereunder to the extent of such Revolving Loans. All payments on the Reimbursement Obligations (including any interest earned thereon) shall be made to the Agent for the account of the Banks in U.S. dollars and in immediately available funds, without set-off, deduction, or counterclaim.

          (e) Reimbursement Obligations Absolute. The Reimbursement Obligations of the Borrower under this Agreement shall be absolute, unconditional, and irrevocable, and shall be performed

strictly in accordance with the terms of the Loan Documents under all circumstances whatsoever and the Borrower hereby waives any defense to the payment of the Reimbursement Obligations based on any circumstance whatsoever, including, in any case, the following circumstances: (i) any lack of validity or enforceability of any Letter of Credit or any other Loan Document; (ii) any amendment or waiver of or any consent to departure from any Loan Document; (iii) the existence of any claim, set-off, counterclaim, defense, or other rights which the Borrower or any other Person may have at any time against any beneficiary of any Letter of Credit, the Agent, the Issuer, the Banks or any other Person, whether in connection with any Loan Document or any unrelated transaction; (iv) any statement, draft, or other documentation presented under any Letter of Credit proving to be forged, fraudulent, invalid, or insufficient in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; (v) payment by the Issuer under any Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit; or (vi) any other circumstance whatsoever, whether or not similar to any of the foregoing; provided that Reimbursement Obligations with respect to a Letter of Credit may be subject to avoidance by the Borrower if the Borrower proves in a final non-appealable judgment that it was damaged and that such damage arose directly from the Issuer’s willful misconduct or gross negligence.

          (f) Issuer Responsibility. The 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; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower from pursuing such rights and remedies as it shall have against the beneficiary, at law or under any other agreement.. None of the Agent, the Issuer, the other Banks, or any of their respective officers or directors shall have any responsibility or liability to the Borrower or any other Person for: (i) 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 Issuer; (ii) errors, omissions, interruptions, or delays in transmission or delivery of any messages; (iii) 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; (iv) the payment by the Issuer 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 (v) any other circumstance whatsoever in making or failing to make any payment under a Letter of Credit. The Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary. Notwithstanding anything to the contrary contained in this Section 2.08, Borrower shall retain any and all rights it may have against any Issuer for any liability arising out of the gross negligence or willful misconduct of such Issuer.

          (g) Replacement of Issuer. The Issuer may be replaced at any time by written agreement among the Borrower, the Agent, and the successor Issuer, and if requested by the Agent the Issuer. The Agent shall notify the Banks of any such replacement of the Issuer. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuer pursuant to Section 2.08(c). From and after the effective date of any such replacement, (i) the successor Issuer shall have all the rights and obligations of the Issuer under this Agreement with respect to Letters of Credit to be issued thereafter, and (ii) references herein to the term “Issuer” shall be deemed to refer to such successor or to any previous Issuer, or to such successor and all previous Issuers, as the context shall require. After the replacement of an Issuer hereunder, the replaced Issuer shall remain a party hereto and shall continue to have all the rights and obligations of an Issuer under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

     Section 2.09. Obligations Several. The failure of any Bank to make its pro rata share of any Advance required to be made by it shall not relieve any other Bank of its obligation, if any, under this Agreement to make its pro rata share of any Advance required to be made by it, but no Bank shall be responsible for the failure of any other Bank to make any portion of an Advance required to be made by such other Bank.

     Section 2.10. Non-Receipt of Funds by the Agent. Unless the Agent shall have been notified by a Bank or the Borrower (the “Payor”) prior to the date on which such Bank is to make payment to the Agent hereunder or the Borrower is to make a payment to the Agent for the account of one or more of the Banks, as the case may be (such payment being herein called the “Required Payment”), which notice shall be effective upon receipt, that the Payor does not intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient on such date and, if the Payor has not in fact made the Required Payment to the Agent, (a) the recipient of such payment shall, on demand, pay to the Agent the amount made available to it together with interest thereon in respect of the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to the Federal Funds Rate for such period, and (b) the Agent shall be entitled to offset against any and all sums to be paid to such recipient, the amount calculated in accordance with the foregoing clause (a).

     Section 2.11. Adjustments to Interest Rate. Notwithstanding any other provision of this Agreement, the Notes, or the Loan Documents, after the Conversion Date, the rate of interest under any Loan which bears interest at a variable rate, shall be adjusted according to the following schedule should the Owner’s Equity of the Borrower achieve the levels set forth below:

Owner’s Equity		Interest Rate
Greater than 50.00% and less than 60.00%		Applicable LIBOR Rate plus 265 basis points
Greater than or equal to 60.00% and less than 70.00%		Applicable LIBOR Rate plus 235 basis points
Greater than 70.00%		Applicable LIBOR Rate plus 200 basis points
Greater than or equal to 60.00% and total Debt/EBITDA is less than or equal to 1.00		Applicable LIBOR Rate plus 200 basis points
Greater than or equal to 70.00% and total Debt/EBITDA is less than or equal to 1.00		Applicable LIBOR Rate plus 150 basis points

Upon delivery of the fiscal year end audited Financial Statements and the Compliance Certificate pursuant to Section 5.01(c)(i) beginning with the first fiscal year end after the Conversion Date, the rate of interest shall automatically be adjusted in accordance with the 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 following the month in which the Agent received the fiscal year end audited Financial Statements and

related Compliance Certificate. With respect to this Section 2.11, 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 Owner’s Equity within the period of time required by Section 5.01(c)(i) 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 two hundred ninety (290) basis points, such automatic adjustments: (a) to take effect as of the first Business Day after the last day on which the Borrower was required to deliver the applicable Compliance Certificate in accordance with Section 5.01(c)(i) hereof or in the case of an Event of Default, on the date the written notice thereof 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, on the date on which such Event of Default has been waived or cured.

     Section 2.12. 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 Agent should raise a substantial question as to whether it is) unlawful for the Banks to make, maintain or fund LIBOR Rate Loans, then: (a) the Agent shall promptly notify each of the other parties hereto; and (b) the obligation of the Banks 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, the Banks shall make loans to the Borrower that are deemed lawful and that as closely as possible reflect the terms of this Agreement.

     Section 2.13. 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 Agent for the account of the Banks in U.S. dollars and in immediately available funds, subject to Sections 2.17 and 2.18, without set-off, deduction, or counterclaim, not later than 12:00 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 Agent the sums payable under the Loan Documents to which such payment is to be applied and in the event that the Borrower fails to so specify or if an Event of Default exists, the Agent 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. The Agent may apply all payments received from the Guarantor for the benefit of the Borrower to the Loan Obligations in such order and manner as the Agent 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) Pro Rata Treatment. Except to the extent otherwise provided herein: (i) each Advance shall be made by the Banks, and each payment of fees under Section 2.08(c) and Section 2.27 shall

be made for the account of the Banks pro rata according to their respective Pro Rata Share; (ii) each payment and prepayment of principal of or interest on Advances or Reimbursement Obligations by the Borrower (including payments made under Section 2.06) shall be made to the Agent for the account of the Agent or the Banks holding such Advances or Reimbursement Obligations (or participation interests therein) pro rata in accordance with the respective unpaid principal amounts of such Advances or funded participation interests held by such Banks (provided that only the Swingline Bank shall be entitled to principal and interest on the Swingline Advances unless the other Banks have funded their participations therein and the Issuer shall be entitled to principal and interest on the Reimbursement Obligations unless the other Banks have funded their participations therein); (iii) the Banks (other than the Issuer) shall purchase from the Issuer participations in the Letters of Credit pro rata according to their respective Pro Rata Shares; and (iv) the Banks (other than the Swingline Bank) shall purchase from the Swingline Bank participations in the Swingline Advances pro rata according to their respective Pro Rata Shares.

          (e) Proceeds of Collateral. All proceeds received by the Agent for the account of the Banks 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 Agent and the Banks hereunder, including under Section 8.04 and then to all other unpaid or unreimbursed Loan Obligations (including reasonable attorneys’ fees and expenses) owing to the Agent or the Banks 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 (other than contingent indemnification obligations not then due) have been paid and satisfied in full and all Commitments terminated, any remaining 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.

          (f) Noncash Proceeds. Notwithstanding anything contained herein to the contrary, if the Agent shall ever acquire any Collateral through foreclosure or by a conveyance in lieu of foreclosure or by retaining any of the Collateral in satisfaction of all or part of the Loan Obligations or if any proceeds of Collateral received by the Agent to be distributed and shared pursuant to Section 2.13(e) are in a form other than immediately available funds, the Agent shall not be required to remit any share thereof under the terms hereof and the Banks shall only be entitled to their undivided interests in the Collateral or noncash proceeds as determined by this Section 2.13(f). The Banks shall receive the applicable portions (in accordance with Section 2.13(e)) of any immediately available funds consisting of proceeds from such Collateral or proceeds of such noncash proceeds so acquired only if and when received by the Agent in connection with the subsequent disposition thereof. While any Collateral or other property to be shared pursuant to Section 2.13(e) is held by the Agent pursuant to this Section 2.13(f), the Agent shall hold such Collateral or other property for the benefit of the Banks and all matters relating to the management, operation, further disposition or any other aspect of such Collateral or other property shall be resolved by the agreement of the Required Banks.

          (g) Return of Proceeds. If at any time payment, in whole or in part, of any amount distributed by the Agent hereunder is rescinded or must otherwise be restored or returned by the Agent as a preference, fraudulent conveyance, or otherwise under any bankruptcy, insolvency, or similar law, then each Person receiving any portion of such amount agrees, upon demand, to return the portion of such amount it has received to the Agent.

          (h) Sharing of Payments. If a Bank shall obtain payment of any principal of or interest on any of the Loan Obligations owed to such Bank hereunder directly (and not through the Agent) through the exercise of any right of set-off, banker’s lien, counterclaim or similar right, or otherwise, such Bank shall promptly purchase from the other Banks participations in the Loan Obligations owed hereunder held by the

other Banks in such amounts, and make such other adjustments from time to time as shall be equitable to the end that all the Banks shall share the benefit of such payment pro rata in accordance with the unpaid principal of and interest on the Loan Obligations then owed hereunder to each of them. To such end, all of the Banks shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if all or any portion of such excess payment is thereafter rescinded or must otherwise be restored. The Borrower agrees, to the fullest extent it may effectively do so under applicable law, that any Bank so purchasing a participation in the Loan Obligations held by the other Banks may exercise all rights of set-off, banker’s lien, counterclaim, or similar rights with respect to such participation as fully as if such Bank were a direct holder of the Loan Obligations in the amount of such participation. Nothing contained herein shall require any Bank to exercise any such right or shall affect the right of any Bank to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower.

          (i) 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 three hundred sixty five (365) days, as appropriate. Interest shall accrue from and include the date of borrowing, but exclude the date of payment.

     Section 2.14. Default Interest. In addition to the rights and remedies set forth in this Agreement and the Loan Documents: (a) if the Borrower fails to make any payment to the Agent for the account of the Banks when due, then at the Agent’s option in each instance upon notice to the Borrower, the overdue Loan Obligations shall bear interest from the date due to the date paid at two percent (2%) per annum in excess of the rate of interest that would otherwise be applicable to the Loan Obligation; (b) upon the occurrence and during the continuance of an Event of Default beyond any applicable cure period, if any, at the Agent’s option in each instance upon notice to the Borrower, the unpaid principal balances of the Loans shall bear interest from the date of the Event of Default or such later date as the Agent shall elect at two percent (2%) per annum in excess of the rate(s) of interest that would otherwise be in effect on the Loans under the terms of this Agreement; (c) after the maturity of any Loan, whether by reason of acceleration or otherwise, the unpaid principal balance of the Loan (including principal, interest, fees and expenses) shall automatically bear interest at two percent (2%) per annum in excess of the rate of interest that would otherwise be in effect on the Loan under the terms of this Agreement. 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 2.15. Late Charge. If any payment due under this Agreement is not paid within ten (10) days of the due date thereof, the Borrower shall, in addition to such amount, pay on demand of the Agent a late charge equal to five percent (5%) of the amount of such payment.

     Section 2.16. Prepayment of Loans. The Borrower may, at anytime and from time to time, upon thirty (30) days advance written notice to the Agent or such shorter notice period agreed to by the Agent, prepay the outstanding amount of the Loans in whole or in part with accrued interest to the date of such prepayment on the amount prepaid, without penalty or premium, except as and to the extent specifically provided in this Section 2.16. In the event the Construction Loan, the Term Loan or the Term Revolving Loan is prepaid in whole, from the Closing Date through the first twenty-four (24) months after the Conversion Date, the Borrower shall pay a prepayment fee equal to the following specified percentage of the amount of principal prepaid:

Closing Date – Month 12 after Conversion Date			1.00	%
Months 13 – 24 after Conversion Date			0.50	%

Notwithstanding the foregoing, no prepayment fee shall be required if such prepayment is made pursuant to Section 2.25. 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 fee applicable to that fixed interest rate, if any.

     Section 2.17. Withholding Taxes. (a) All payments by the Borrower of amounts payable under any Loan Document shall be payable without deduction for or on account of any present or future taxes, duties, or other charges levied or imposed by any governmental authority through withholding or deduction with respect to any such payments (but excluding (i) any tax imposed on or measured by the net income or profit of a Bank and (ii) any branch profits tax imposed by the United States of America or any similar tax imposed by any other jurisdiction in which the Borrower is located) (all such taxes, duties or other charges, giving effect to the taxes excluded pursuant to the foregoing parenthetical herein the “Non-Excluded Taxes”). If any Non-Excluded Taxes are so levied or imposed, the Borrower shall make additional payments in such amounts so that every net payment of amounts payable by them under any Loan Document, after withholding or deduction for or on account of any Non-Excluded Taxes, will be equal to the amount provided for herein or therein; provided that the Borrower may withhold to the extent required by law and shall have no obligation to pay such additional amounts to any Bank to the extent that such Non-Excluded Taxes are (i) levied or imposed by reason of the failure or inability of such Bank to comply with the provisions of Section 2.18, (ii) United States withholding taxes imposed on amounts payable to such Bank at the time the Bank becomes a party to the Loan Documents, except to the extent that such Bank’s assignor (if any) was entitled, at the time of assignment, to receive additional amounts from the Borrower with respect to such Non-Excluded Taxes pursuant to this Section 2.17, (iii) backup withholding taxes under Section 3406 of the Code or (iv) taxes (including penalties or interest) that are attributable to a Bank’s or the Agent’s gross negligence or willful misconduct. The Borrower shall furnish promptly to the Agent for distribution to each affected Bank, as the case may be, official receipts evidencing any such withholding or reduction.

          (b) Refund. If the Agent or any Bank determines that it has received a refund of any taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.17, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional mounts paid, by the Borrower under this Section 2.17 with respect to the taxes giving rise to such refund), net of all out-of-pocket expenses of the Agent or such Bank and without interest (other than any interest paid by the relevant governmental authority with respect to such refund).

     Section 2.18. Withholding Tax Exemption.

          (a) Each Bank that is not incorporated or organized under the laws of the United States of America or a state thereof (a “Non-U.S. Bank”) agrees that it will deliver to the Borrower and the Agent on the Closing Date (or, in the case of an assignee, on the date of assignment) two duly completed copies of either United States Internal Revenue Service Form W8-ECI or W8-BEN (or any applicable successor form), certifying in either case that such Non-U.S. Bank is entitled to receive payments from the Borrower under any Loan Document without deduction or withholding of any United States federal income taxes. In the case of a Non-U.S. Bank claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(s) of the Code, with respect to payments of “portfolio interest”, it will deliver to the Borrower and the Agent on the Closing Date (or, in the case of an assignee, on the date of assignment) two Form W-8 (or any subsequent versions thereof or successors thereto) properly completed and duly executed by such Non-U.S. Bank claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under the Loan Documents. Each other Bank agrees to deliver to the Borrowers and the Agent on or prior to the Closing Date, or in the case of a Bank that is an assignee or transferee of an interest under this

Agreement (unless the respective Bank was already a Bank under immediately prior to such assignment or transfer), on the date of such assignment or transfer to such Bank, one or more accurate and complete original signed copies (as the Borrower or Agent may reasonably request) of United States Internal Revenue Service Form W-9 or successor applicable form (if required by law), as the case may be, providing the employer identification number for such Bank. Each Bank which so delivers any form described in this Section 2.18(a) further undertakes to deliver to the Borrower and the Agent two (2) additional copies of such form on or before the date such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by the Borrower or the Agent, in each case certifying that such Bank is entitled to receive payments from the Borrower under any Loan Document without deduction or withholding of any United States federal income taxes, unless an event (including any change in treaty, law, or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Bank from duly completing and delivering any such form with respect to it and such Bank advises the Borrower and the Agent that it is not capable of receiving such payments without any deduction or withholding of United States federal income tax.

          (b) A Bank that is entitled to an exemption from or reduction of non-U.S. withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate; provided, that such Bank is legally entitled to complete, execute and deliver such documentation if in such Bank’s reasonable judgment such completion, execution or submission would not materially prejudice the legal position of such Bank.

          (c) If the form provided by a Bank at the time such Bank first becomes a party to this Agreement indicates a U.S. interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Non-Excluded Taxes unless and until such Bank provides the appropriate form certifying that a lesser rate applies, whereupon withholding tax at such lesser rate shall be considered excluded from Non-Excluded Taxes only for periods governed by such form.

     Section 2.19. Maximum Amount Limitation. Anything in this Agreement, any Note, or the other Loan Documents to the contrary notwithstanding, the 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 to the extent that any of the fees payable by the Borrower for the Loan Obligations to the Banks 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 Banks under their Notes, 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 Banks, 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 the Banks in connection therewith. This Section 2.19 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 2.19 shall be deemed to be incorporated in every Loan Document and communication related thereto.

     Section 2.20. Bank Records. All Advances and all payments or prepayments made thereunder on account of principal or interest may be evidenced by each of the Banks 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.

     Section 2.21. Funding of Advances. Upon receipt by the Agent or a Bank of any Request for Advance for any Term Revolving Loan Advance, Revolving Line of Credit Advance or any demand for drawing under a Letter of Credit, the Agent or the Bank shall promptly notify the Borrower and the other Banks as to the amount to be paid as a result of such Request for Advance, demand for drawing and the respective payment date. Any notice pursuant to the forgoing sentence shall specify the amount to be paid as a result of such Request for Advance, demand for drawing and the respective payment date. Not later than 12:00 P.M. (Minneapolis, Minnesota time) on the applicable payment date each Bank will make available to the Agent, in immediately available funds, an amount equal to such Bank’s Pro Rata Share of the amount to be paid as a result of such Request for Advance, demand or drawing.

     Section 2.22. Participation Obligations Absolute; Failure to Fund Participation. The obligations of a Bank to fund its participation in the Letters of Credit and Swingline Advances in accordance with the terms hereof shall be absolute, unconditional, and irrevocable and shall be performed strictly in accordance with the terms of the Loan Documents under all circumstances whatsoever, including the following circumstances: (a) any lack of validity of any Loan Document; (b) the occurrence of any Event of Default; (c) the existence of any claim, set-off, counterclaim, defense, or other right which such Bank, the Borrower or any other Person may have; (d) the occurrence of any event that has or could reasonably be expected to have a material adverse effect on the financial conditions or operation of any Bank and its Subsidiaries; (e) the failure of any condition to an Advance or the issuance of a Letter of Credit under this Agreement to be satisfied; (f) the fact that after giving effect to the funding of the participation the Outstanding Revolving Advances may exceed the Borrowing Base; or (g) any other circumstance whatsoever, whether or not similar to any of the foregoing. If a Bank fails to fund its participation in a Letter of Credit or a Swingline Advance as required hereby, such Bank shall remain obligated to pay to the Issuer or the Swingline Bank, as applicable, the amount it failed to fund on demand together with interest thereon in respect of the period commencing on the date such amount should have been funded until the date the amount was actually funded to the applicable Person at a rate of interest equal to the Federal Funds Rate for such period and such Person shall be entitled to offset against any and all sums to be paid to such Bank hereunder the amount due such Person under this sentence.

     Section 2.23. Farm Credit System Entity Equity Interests. So long as any of the entities identified in Schedule 2.23 is a Bank under this Agreement, the Borrower will acquire equity in such Farm Credit System Entities (an “FCS Entity”) in such amounts and at such times as the FCS Entities may require in accordance with the FCS Entities’ Bylaws and Capital Plans (as each may be amended from time to time), except that the maximum amount of equity that the Borrower may be required to purchase in the FCS Entities in connection with the Loans and Swingline Loans made by the FCS Entities under this Agreement shall not exceed the maximum amount permitted by the FCS Entities’ Bylaws as of the date of this Agreement. The

rights and obligations of the parties with respect to such equity and any distributions made on account thereof or on account of the Borrower’s patronage with the FCS Entities shall be governed by the FCS Entities’ Bylaws, except that if the FCS Entities sell a participation in a portion of any Loans due to the FCS Entities, the sold portion of the Loans due to the FCS Entities shall not be entitled to patronage distributions. A sale of participation interest may include certain voting rights of the participants (to the extent otherwise permitted under Section 8.08) regarding the loans hereunder. The Borrower hereby consents and agrees that the amount of any distributions with respect to the Borrower’s patronage with the FCS Entities that are made in qualified written notices of allocation and that are received by the Borrower from the FCS Entities will be taken into account by the Borrower at the stated dollar amounts whether the distribution is evidenced by a stock certificate or other form of written notice that such distribution has been made and recorded in the Borrower’s name on the FCS Entities’ records. The Loans due to the FCS Entities under this Agreement and other Indebtedness due to the FCS Entities hereunder shall be secured by a statutory first lien on all equity that the Borrower may now own or hereafter acquire in the FCS Entities. Such equity shall not, however, constitute security for Indebtedness due to any other Bank under this Agreement. The FCS Entities shall not be obligated to set off or otherwise apply such equities to the Borrower’s Indebtedness to the Bank.

     Section 2.24. Compensation. Upon the request of the Agent, the Borrower shall pay to the Agent for the account of the Banks such amount or amounts as shall be sufficient (in the reasonable opinion of the Agent) to compensate it for any loss, cost, or expense (excluding loss of anticipated profits incurred by it) as a result of: (a) 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 (b) any failure by the Borrower for any reason (including 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: (y) 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 borrow, 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 (z) the amount of interest (as reasonably determined by the Agent), which would have accrued to the Banks 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 2.24 shall survive the repayment of the Loans and other obligations under the Loan Documents hereunder.

     Section 2.25. Excess Cash Flow. In addition to all other payments of principal and interest required under this Agreement, at the end of the first full fiscal quarter following the Conversion Date, and continuing each fiscal quarter thereafter until the Maturity Date, the Borrower shall remit to the Agent for the account of the Banks within five (5) days of delivery of the Financial Statements used to calculate the applicable Excess Cash Flow, an amount equal to one hundred percent (100%) of the Borrower’s Excess Cash Flow, calculated based upon, with respect to the first three fiscal quarters of each fiscal year of the Borrower, that fiscal quarter’s interim Financial Statements, on or before sixty (60) days after the end of each such fiscal quarter of the Borrower and, with respect to the fourth fiscal quarter of the Borrower, the annual Financial Statements of the Borrower required to be delivered pursuant to Section 5.01(c)(i), on or before one hundred and twenty (120) days after the end of each fiscal year of the Borrower (the “Excess Cash Flow Payment”), provided however, that the total Excess Cash Flow Payments required hereunder shall not exceed One Million Two Hundred Fifty Thousand and No/100 Dollars ($1,250,000.00) in any fiscal quarter or Five Million and No/100 Dollars ($5,000,000.00) in any fiscal year (the “Maximum Excess Cash Flow Payment”). One hundred percent (100%) of the Excess Cash Flow Payment shall be applied to the reduction of the outstanding principal balance of the Term Loan in the inverse order of maturity. The Excess Cash Flow Payment shall be

re-calculated annually based upon audited fiscal year-end Financial Statements required by Section 5.01(c)(i). If any such recalculation evidences an underpayment by the Borrower for such fiscal year, then any time after the audited annual Financial Statements are required to be delivered pursuant to Section 5.01(c)(i), the Borrower shall within thirty (30) days of the Agent’s request remit to the Agent for the account of the Banks any additional amounts, resulting from such underpayment, to the Agent for the account of the Banks under this Section in an amount not to exceed the Maximum Excess Cash Flow Payment. If any such recalculation by the Borrower or the Agent evidences an overpayment by the Borrower for such fiscal year, the Borrower may reduce its next Excess Cash Flow Payment due by the amount of such overpayment until the entire overpayment is applied. Any Excess Cash Flow Payment or any other payment from Excess Cash Flow shall not constitute a prepayment with respect to which a prepayment fee under Section 2.16 is required to be paid. Notwithstanding the foregoing, the requirement to make an Excess Cash Flow Payment for any fiscal quarter shall not apply if Owner’s Equity is greater than or equal to sixty percent (60%), but will be reinstated if Owner’s Equity falls below sixty percent (60%), in each case measured for such fiscal quarter or year end, as the case may be. Notwithstanding the foregoing, the Excess Cash Flow Payment shall not exceed an aggregate amount of Twenty-five Million and No/100 Dollars ($25,000,000.00) during the term of this Agreement.

     Section 2.26. Administrative Fee. The Borrower agrees to pay to the Agent, for Agent’s own and sole account and not for the account of the Banks, the fees in the amounts determined from time to time by the agreement of the Borrower and the Agent and as set forth in a separate letter agreement between the Borrower and the Agent dated as of the date of this Agreement. Such fees shall be deemed fully earned and non-refundable on the due date thereof.

     Section 2.27. Commitment Fee. The Borrower agrees to pay to the Agent for the account of each Bank a commitment fee on the average daily unused portion of such Bank’s Revolving Commitment from the Conversion Date until the Term Revolving Loan Termination Date or the Revolving Line of Credit Termination Date, as the case may be, at the rate of twenty-five (25) basis points on a per annum basis, payable in arrears in quarterly installments on each Quarterly Payment Date during the term of such Bank’s Revolving Commitment, and on the Term Revolving Loan Termination Date and/or the Revolving Line of Credit Termination Date. For purposes of this Agreement, the unused portion of a Bank’s Revolving Commitment for any measurement period shall be the positive difference, if any, of (a) the average daily amount of such Bank’s Revolving Commitment, minus (b) the Bank’s Pro Rata Share of the average daily outstanding Revolving Advances and Revolving Letter of Credit Liabilities, but shall not, for purposes of this Section 2.27 only, be deemed utilized by any Swingline Advances unless the Banks’ participations therein are funded in accordance with Section 2.06.

     Section 2.28. Mitigation Obligations; Replacement of Banks.

          (a) If the Borrower is required to pay any additional amount to any Bank or any governmental authority for the account of any Bank pursuant to Section 2.17, then such Bank shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates if such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.17 in the future and (ii) would not subject such Bank to any unreimbursed cost or expense and would not otherwise be materially disadvantageous to such Bank. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Bank in connection with any such designation or assignment.

          (b) Anything contained herein to the contrary notwithstanding, if the Borrower is required to pay any additional amount to a Bank or any Governmental Authority for the account of a Bank pursuant to Section 2.17, or if a Bank defaults in its obligation to fund Loans hereunder or if a Bank has

become insolvent and its assets become subject to a receiver, liquidator, trustee, custodian or other officer having similar powers, then the Borrower may, at its sole expense and effort, upon notice to such Bank and the Agent, require such Bank to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 8.07), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Bank, if a Bank accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Agent to the extent required by Section 8.07, which consent shall not unreasonably be withheld, (ii) such Bank shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such payments. If, in connection with any proposed amendment, waiver or consent with respect to any of the provisions hereof as contemplated by Section 8.01 hereof, the consent of the Required Banks shall have been obtained, but the consent of one or more other Banks (each, a “Non-Consenting Bank”) whose consent is required shall not have been obtained, then, with respect to each such Non-Consenting Bank, the Borrower may, by giving notice to the Agent and such Non-Consenting Bank of its election to do so, elect to cause such Non-Consenting Bank (and such Non-Consenting Bank hereby irrevocably agrees) to assign its outstanding Loans and its Commitments, if any, to one or more Assignees (each, a “Replacement Bank”) in accordance with the provisions of Section 8.07(b) of this Agreement. The Non-Consenting Bank shall pay the fees, if any, payable thereunder in connection with any such assignment from such Non-Consenting Bank, provided, that (i) on the date of such assignment, the Replacement Bank shall pay to the Non-Consenting Bank an amount equal to the sum of (A) an amount equal to the principal of, and all accrued interest on, all outstanding Loans of such Non-Consenting Bank, (B) an amount equal to all unreimbursed drawings that have been funded by such Non-Consenting Bank, together with all then unpaid interest with respect thereto at such time and (C) an amount equal to all accrued but theretofore unpaid fees owing to such Non-Consenting Bank pursuant to Section 2.27, (ii) on the date of such assignment, the Borrower shall pay any amounts payable to the Non-Consenting Bank pursuant to Sections 2.24 or 2.29 or this Section 2.28 or otherwise as if it were a prepayment and (iii) each Replacement Bank shall consent, at the time of such assignment, to each matter in respect of which such Non-Consenting Bank was a Non-Consenting Bank, provided, further, that the Borrower may not make any such election with respect to any Non-Consenting Bank which is also the Issuer unless, prior to the effectiveness of such election, the Borrower shall have caused each outstanding Letter of Credit issued by such Non-Consenting Bank to be cancelled, fully cash collateralized or supported by a “back to back” Letter of Credit reasonably satisfactory to the Non-Consenting Bank.

Section 2.29. Reserves on LIBOR Rate Loans. The Borrower shall pay to each Bank, as long as such Bank shall be required under regulations of the Board of Governors of the Federal Reserve System to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency liabilities (as defined in Regulation D), additional interest on the unpaid principal amount of each LIBOR Rate Loan of such Bank equal to the actual costs of such reserves allocated to such Loan by such Bank (as determined by such Bank in good faith, which determination shall be conclusive absent manifest error), which shall be due and payable on each date on which interest is payable on such Loan, provided that the Borrower shall have received at least 10 days’ prior written notice (with a copy to the Agent) of such additional interest from such Bank. If a Bank fails to give written notice 10 days prior to the last day of the relevant Interest Period, such additional interest shall be due and payable 10 days from receipt of such written notice.

     Section 2.30 Debt Service Reserve Account. In addition to all other payments required under this Agreement, on the first fiscal quarter end following the Conversion Date, as soon as available, but in no event later than thirty (30) days after the end of such fiscal quarter, Borrower shall deposit an amount that is not less than one quarterly payment of principal and interest due under the Term Loan and from time to time

thereafter, upon written notice from the Agent, additional or lesser amounts to account for changes in the quarterly principal and interest payment amounts due (together, the “Required Debt Service Reserve Deposit Amount”) into the Debt Service Reserve Account. The interest rate for purposes of the preceding sentence shall be the applicable interest rate on the Term Loan for the immediately preceding Quarterly Payment Date such a payment is due. Thereafter, (i) on any Monthly Payment Date on which the aggregate amount in the Debt Service Reserve Account is less than the Required Debt Service Reserve Deposit Amount, Borrower shall, as soon as available, but in no event later than five (5) Business Days after such Monthly Payment Date, deposit amounts into the Debt Service Reserve Account to restore the balance in such account to the Required Debt Service Reserve Deposit Amount, or (ii) at any time upon receipt of written notice from the Agent that the amount in the Debt Service Reserve Account is less than the Required Debt Service Deposit Amount, Borrower shall, as soon as available, but in no event later than five (5) Business Days after receipt of such notice, deposit amounts into the Debt Service Reserve Account to restore the balance in such account to the Required Debt Service Reserve Deposit Amount. Any Affiliated Borrower may restore the balance of any other Affiliated Borrower’s Required Debt Service Reserve Deposit Amount through loans from other US Bio Entities, provided that no loan between Affiliated Borrowers may be made if, on the date such loan is made, an Event of Default has occurred and is continuing or would result therefrom, except for the Event of Default arising as a result of Borrower’s failure to restore the required balance of the Debt Service Reserve Account. As and when any Obligation is past due, after any applicable grace periods have expired, under any Loan Document, Agent, in its sole discretion, may withdraw from the Debt Service Reserve Account, for a credit to its own account to be held for the benefit of the Banks, the amount of the then past due Obligation. Notwithstanding the foregoing sentence, Agent shall have no obligation to withdraw any portion of the Debt Service Reserve Account: (i) if an Event of Default has occurred and is continuing under the Loan Documents, or (ii) to withdraw any of the Debt Service Reserve Account for any other purpose other than for which the Debt Service Reserve Account was established, provided that if an Event of Default has occurred and is continuing, the Agent may withdraw amounts in the Debt Service Reserve Account, in its sole discretion, for the payment of any Obligation then past due, after any applicable grace periods have expired, in such order and manner as is consistent with the Agent’s obligations set forth in this Agreement. Withdrawals by the Agent of any amounts from the Debt Service Reserve Account to pay any Obligation then past due after any applicable grace periods have expired, may be made without the requirement of any consent by or notice to the Borrower, provided that Agent shall provide to Borrower and to each Affiliated Borrower, within five (5) Business Days after any withdrawal from the Debt Service Reserve Account is made by Agent, notice that such withdrawal was made and the Obligation such withdrawal was applied to and, if applicable, that the Debt Service Reserve Account is then below the Required Debt Service Reserve Deposit Amount. Notwithstanding the foregoing, Borrower recognizes and acknowledges that its obligation to pay required Obligations are absolute and unconditional and it is not dependent upon sufficient deposits in the Debt Service Reserve Account being available to make payment on any Obligation, and nothing herein shall be construed to negate or modify the Borrower’s absolute and unconditional obligation to pay the Obligations in accordance with the terms and conditions of this Agreement and the Loan Documents.

     2.31 Commitment Termination. The Borrower may terminate any or all of the Commitments at any time upon five (5) Business Days prior written notice to the Agent or shorter notice period agreed to be the Agent, provided, that upon receipt of such notice by the Agent, no Bank shall be committed to make any further Advance to the Borrower under any Loan under any Commitment so terminated, and that such notice shall not terminate any Obligations of the Borrower under any Loan Document.

If it reasonably appears to the Agent that any change may increase the Project Costs by an amount greater than $50,000.00 the Agent may require the Borrower to deposit additional funds with the Agent pursuant to Section 2.02(g) of this Agreement in an amount sufficient to cover the increased costs as a condition to giving its approval if so required pursuant to Section 2.02(g);

               (v) comply with and keep in effect all necessary permits and approvals required to be obtained from any Governmental Authority relating to the lawful construction of the Project.

               (vii) upon completion of the building foundation of the Project, deliver to the Agent an “as-built” survey of the Real Property which: (A) sets forth the location and exterior lines of the Real Property and includes any and all improvements completed on the Real Property; (B) demonstrates compliance with all applicable setback requirements; (C) demonstrates that the Project is entirely within the exterior boundaries of the Real Property and any building restriction lines and does not encroach upon any easements or rights-of-way; and (D) contains such other information as the Agent may reasonably request;

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

               (ix) pay and discharge all claims and liens for labor done and materials and services furnished in connection with the construction of the Project other than such claims and liens contested in good faith, and other than claims and liens to be paid pursuant to the terms of a Construction Contract; provided that the Borrower may diligently contest in good faith any claim or lien, provided that it does not adversely affect the Borrower’s ability to obtain title insurance in the manner required by this Agreement and the Disbursing Agreement. Upon the Agent’s reasonable request, the Borrower will promptly provide a bond, cash deposit, or other security reasonably satisfactory to the Agent and reasonably necessary to protect the Agent’s interest and security should such contest be unsuccessful;

               (x) at the Agent’s reasonable request and expense, post signs which the Borrower has previously approved (as to form and location) on the Real Property for the purpose of identifying the Agent as a lender for the Project.

               (xi) on and after commencement of construction of the Project and until the date the Project becomes operational, maintain in force builder’s risk insurance in such amounts, form, risk coverage, deductibles, insurer, loss payable and cancellation provisions as reasonably required by the Agent. The Agent’s approval, however, will not be a representation of the solvency of any insurer or the sufficiency of any amount of insurance;

               (xii) pay the Agent’s reasonable and documented 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 this Agreement, including but not limited to reasonable and documented out of pocket costs and expenses relating to title insurance and escrow charges, disbursing agent fees, recording charges, mortgage taxes, and reasonable legal fees and disbursements. The provisions of this paragraph will survive the termination of this Agreement, and the repayment of the Loans;

               (xiii) if required by the Agent, the Borrower will submit to the Agent at such times as it reasonably requires (which will in no event be more often than monthly) a statement which accurately shows the application of all funds expended to date for construction of the Project and the source of those funds as well as the Borrower’s best estimate of the funds needed to complete the Project and the source of

those funds. The Borrower will promptly supply the Agent with any Financial Statements or other information concerning its affairs and properties as the Agent may reasonably request, and will promptly notify the Agent of any material adverse change in its financial condition or in the physical condition of the Property or Project;

               (xiv) comply in all material respects with the requirements of any commitment or agreement entered into by the 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; and

Upon demand by the Agent, the Borrower will defend any action or proceeding brought against the Agent alleging any defective workmanship or materials, or the Agent may elect to conduct its own defense, and the Borrower shall reimburse the Agent for the reasonable and documented out-of-pocket costs of such defense. The provisions of this paragraph will survive the termination of this Agreement, and the repayment of the Loans.

          (s) Banks’ Reliance. The Borrower acknowledges that the Agent and the Banks are entering into the transactions contemplated by this Agreement in reliance upon the Borrower’s identity as a legal entity that is separate from any other US Bio Entity. Therefore, from and after the date of execution and delivery of this Agreement, the Borrower shall take all reasonable steps including all steps that the Agent may from time to time reasonably request to maintain the Borrower’s identity as a separate legal entity and to make it manifest to third parties that the Borrower is an entity with assets and liabilities distinct from those of any other US Bio Entity, and not just a division of any US Bio Entity, in each case consistent with past practices. Without limiting the generality of the foregoing and in addition to the other covenants set forth herein, the Borrower shall:

          (i) observe all organizational and governance formalities as a distinct legal entity;

          (ii) maintain the Borrower’s books and records separate from those of any other US Bio Entity and otherwise readily identifiable as its own assets rather than assets of any other US Bio Entity; and

          (iii) prepare the Borrower’s Financial Statements separately from those of any other US Bio Entity and insure that any consolidated financial statements of any other US Bio Entity that include the Borrower have detailed notes clearly stating that the Borrower is a separate legal entity and that its assets will be available first to satisfy the claims of the creditors of the Borrower.

          (t) Debt Service Reserve Account. Establish and maintain a Debt Service Reserve Account, and deposit and maintain the Required Debt Service Reserve Deposit Amount in such account in accordance with the provisions of Section 2.30.

reasonably request or require to perfect its Lien in any such accounts of the Borrower, in each case in accordance with the terms and conditions of the Security Agreement.

          (v) Insurance. In case of any loss covered by any policy of casualty insurance held as Collateral, the Agent is hereby authorized at its option and without the consent of the Borrower to settle, adjust and compromise any claim arising out of such policies, and to collect and receive the proceeds payable therefrom; provided, that the Borrower may itself adjust and collect for any losses arising out of a single occurrence aggregating not in excess of $500,000.00, or other amount agreed to by the Agent. Any expense incurred by the Agent in the adjustment and collection of insurance proceeds (including the cost of any independent appraisal of the loss or damage on behalf of the Agent) shall be reimbursed to the Agent first out of any proceeds of such policy of insurance. So long as no Event of Default has occurred and is continuing at the time of releases of such proceeds (other than as a result of such casualty), the proceeds or any part of any casualty proceeds shall be released to the Borrower and shall be applied to the restoration or repair of the Project or to the reduction of the Debt under this Agreement in the inverse order of maturity, whether due or not, without the application of any prepayment premium, the choice of application to be solely at the discretion of the Borrower, and upon the occurrence and continuation of an Event of Default at the sole discretion of the Agent.

          (w) Condemnation. The Borrower shall give the Agent prompt notice of any action, actual or threatened, in condemnation or eminent domain. The Borrower may in good faith contest any condemnation or eminent domain action by appropriate legal action or proceedings. Any such contest shall be prosecuted with due diligence. The Borrower hereby irrevocably agrees that the Agent may, to the extent of the remaining unpaid Debt, receive the proceeds of any award, payment or claim for damages for all or any part of the Project taken or damaged, whether temporary or permanent, under the power of eminent domain or condemnation, and authorizes the Agent to intervene in any such action in the name of the Borrower and to collect and receive from the condemning authorities and give proper receipts and acquaintances for such proceeds. Any expenses incurred by the Agent in intervening in such action or collecting such proceeds shall be reimbursed to the Agent first out of the proceeds. So long as no Event of Default has occurred and is continuing, the proceeds or any part thereof shall be applied upon or in reduction of the Debt under this Agreement in the inverse order of maturity, whether due or not, without the application of any prepayment premium, or to the restoration or repair of the Project, the choice of application to be solely at the discretion of the Borrower, and upon the occurrence and continuation of an Event of Default at the sole discretion of the Agent.

          (x) Restoration of Mortgaged Premises After Loss. Should any insurance or condemnation proceeds be applied to the restoration or repair of the Project the restoration or repair shall be done under the supervision of an engineer reasonably acceptable to the Agent, pursuant to plans and specifications approved by the Agent, and in accordance in all material respects with all applicable building laws, regulations and ordinances, including, but not limited to, the Accessibility Guidelines set forth in the Americans with Disabilities Act. In such case, the proceeds shall be held by the Agent for such purposes and will from time to time be disbursed by the Agent to defray the costs of such restoration or repair under such safeguards and controls as the Agent may reasonably require to assure completion in accordance with the approved plans and specifications and free of Liens other than Permitted Liens. So long as no Event of Default has occurred and is continuing, any surplus which may remain after payment of all costs of restoration or repair may, at Borrower’s option, be applied to the reduction of the Debt under this Agreement in the inverse order of maturity, without application of any prepayment premium, or shall be returned to the Borrower as its interest may appear, the choice of application to be solely at the discretion of the Borrower, and upon the occurrence and continuation of an Event of Default at the sole discretion of the Agent.

          (f) The Borrower shall fail to pay any other Debt of the Borrower having an aggregate principal amount in excess of Five Hundred Thousand and No/100 Dollars ($500,000.00) (either in any individual case or in the aggregate), excluding Debt evidenced by the Notes and excluding Ordinary Trade Payable Disputes, or any interest or premium thereon, when due (whether by scheduled maturity, required prepayment, acceleration, demand or otherwise) and such failure shall continue after the applicable grace or cure period, if any, specified in the agreement or instrument relating to such Debt; or any other default under any agreement or instrument relating to any such Debt, or any other event, shall occur and shall continue after the applicable grace or cure period, if any, specified in such agreement or instrument, if the effect of such default or event is to accelerate, or to permit the acceleration of, the maturity of such Debt (excluding Ordinary Trade Payable Disputes); or any such Debt shall be declared to be due and payable, or required to be prepaid (other than by a regularly scheduled required prepayment or prepayment required to be paid due to voluntary sales or transfer or condemnation of assets securing such Debt), prior to the stated maturity thereof (excluding Ordinary Trade Payable Disputes); or

          (g) The Borrower (i) shall generally not pay its debts as such debts become due, or shall admit in writing its inability to pay its debts generally, or (ii) shall make a general assignment for the benefit of creditors; or any proceeding shall be instituted by or against the Borrower seeking to adjudicate it a bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver,

          (n) The construction of the Project shall be delayed for any reason and for such period that, in the reasonable judgment of the Agent, Substantial Completion of the Project will not occur by the Substantial Completion Date. If such delay is curable and if the Borrower has not been given a notice of a similar breach within the preceding twelve (12) months, it may be cured (and no Event of Default will have occurred) if the Borrower cures the failure within sixty (60) days, which shall include advancing the progress of the Project to the point that, in the reasonable judgment of the Agent, Substantial Completion of the Project will occur by the Substantial Completion Date; or

          (o) The Guaranty shall cease to be in full force and effect or shall be revoked or declared null and void by the Guarantor, or the validity or enforceability thereof shall be contested by the Guarantor, or the Guarantor shall deny any further liability or obligations thereunder; or

          (p) The loss, suspension or revocation of, or failure to renew, any franchise, license, certificate, permit, authorization, approval or the like now held or hereafter acquired by the Borrower or any of its Subsidiaries, if such loss, suspension, revocation or failure to renew could reasonably be expected to have a Material Adverse Effect; or

          (r) Any Material Contract or material Construction Contract shall be terminated, changed, amended or restated, which termination, change, amendment or restatement could reasonably be expected to have a Materially Adverse Effect, without the Agent’s prior consent.

     Section 6.02. Remedies. Upon the occurrence and during the continuance of an Event of Default, the Agent:

          (a) may accelerate the due date of the unpaid principal balance of the Loans, all accrued but unpaid interest thereon and all other amounts payable under this Agreement and the other Loan Documents 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 the Borrower under the Federal Bankruptcy Code, the Loans, 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 Agent to withhold any one or more Advances in its discretion, and terminate the Banks’ obligations, if any, under this Agreement to make any Advances whereupon the commitment and obligations of the Banks to extend credit or to make Advances hereunder shall terminate, and no disbursement of Loan funds by the Agent will cure any default of the Borrower, unless the Required Banks 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 all personal property, including all fixtures and equipment leased, occupied or used by the Borrower, provided that, with respect to Collateral consisting of Intellectual Property which is licensed to the Borrower, only to the extent of the Borrower’s rights therein and to the extent permitted by the various license or other agreements relating thereto. The Borrower hereby irrevocably consents to the appointment of such receiver and agrees to cooperate and assist any such receiver 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 making changes in Construction Documents, work or materials, and entering into, modifying, or terminating any contractual arrangements, subject to the Agent’s right at any time to discontinue any work without liability. If the Agent 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 Agent as its attorney in fact, with full power of substitution, to complete the Project in the Borrower’s name, or the Agent may elect to complete construction in its own name. In any event, all sums expended by the Agent 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 Agent will not have any obligation under the Construction Documents prepared for the Project, any studies, data, and drawings with respect thereto prepared by or for the Borrower, or the contracts and agreements relating to the Construction Documents, or the aforesaid studies, data, and drawings, or to the construction of the Project unless it expressly hereafter agrees in writing. The Agent will have the right to exercise any rights of the Borrower under those contracts and agreements or with respect to such Construction Documents, studies, data, and drawings upon the occurrence and during the continuance of any Event of 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;

          (e) may, by notice to the Borrower, require the Borrower to pledge to the Agent 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 Agent 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 Agent 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 Agent; and

          (f) may exercise all other rights and remedies afforded to the Agent 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 the Agent, 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 the Agent 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.

ARTICLE VII
THE AGENT

     Section 7.01. Authorization and Action. Each Bank hereby appoints and authorizes the Agent to take such action as agent on its behalf and on behalf of each of its Affiliates who are owed Obligations (each such Affiliate by acceptance of the benefits of the Loan Documents hereby ratifying such appointment) and to exercise such powers under this Agreement as are delegated to the Agent by the terms hereof, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement (including enforcement or collection of the Notes), the Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Required Banks; provided, however, that the Agent shall not be required to take any action which exposes the Agent to personal liability or which is contrary to this Agreement or applicable law.

     Section 7.02. Duties and Powers of Agent.

          (a) The Agent shall (i) make such demands and give such notices under the Loan Documents as the Required Banks shall request, (ii) take (or refrain from taking) such action to enforce the Loan Documents and to foreclose or otherwise realize upon, collect or dispose of the Collateral, or any portion thereof, at such times, in such order and otherwise in such matter as may be directed by the Required Banks (including matters relating to (A) the amount of the Loan Obligations bid as a credit on account of the purchase price of the Collateral and (B) the adoption and implementation of post-foreclosure or post-realization plans of disposition with respect to any of the Collateral foreclosed or otherwise realized upon), and (iii) take such other actions under this Agreement or the Loan Documents or otherwise (including the amending of this Agreement or the Loan Documents as contemplated by and in accordance with the provisions of Section 8.01 hereof) upon direction of the Required Banks. Any property taken or held by the Agent, in its capacity as such, by foreclosure or otherwise, shall be held by it pursuant to this Agreement.

          (b) The Agent shall not take, and shall be fully justified in failing or refusing to take, any action under this Agreement or the Loan Documents or otherwise unless it shall have first received such advice or concurrence of the Required Banks.

          (c) Any action taken or failure to act pursuant to the direction of the Required Banks shall be binding upon all of the Banks and all future holders of the Loan Obligations.

          (d) The obligations of the Agent hereunder are only those expressly set forth herein and in the Loan Documents. Without limiting the generality of the foregoing, the Agent shall not be required to take any action with respect to any Event of Default or Default, except as expressly provided in this Agreement. The Agent shall not be deemed to have knowledge or notice of the occurrence of an Event of Default or Default, unless the Agent has received written notice from a Bank or the Borrower describing such default or Event of Default and stating that such notice is a notice of default. In the event the Agent receives such a notice, the Agent shall give notice thereof to the Banks. The Agent shall take such action under the Loan Documents with respect to such Default or Event of Default as shall be directed by the Required Banks.

     Section 7.03. Obligations of Agent. Neither the Agent nor any of its directors, officers, agents, or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Agent (i) may treat the Banks as the parties entitled to distributions hereunder unless and until the Agent receives written notice and evidence satisfactory to it to the contrary, (ii) may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts, (iii) shall not by reason of any Loan Document be a trustee or fiduciary for any Bank, and (iv) shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telegram, cable, telex or facsimile) believed by it in good faith to be genuine and signed or sent by the proper party or parties or by acting upon any representation or warranty of the Borrower made or deemed to be made hereunder. Further, the Agent (A) makes no warranty or representation to any Bank and shall not be responsible to any Bank for the accuracy or completeness of any statements, warranties or representations (whether written or oral) made by the Borrower in or in connection with this Agreement, (B) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement on the part of the Borrower or to inspect the property (including the books and records) of the Borrower, and (C) shall not be responsible to any Bank for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or any other instrument or document furnished pursuant hereto with respect to any other Person party hereto or thereto.

     Section 7.04. Agent and Affiliates. With respect to its Commitment, the Advances made by the Agent and the Notes issued to it, the Agent shall have the same rights and powers under this Agreement as the other Banks and may exercise the same as though it were not the Agent; and the term “Bank” or “Banks” shall, unless otherwise expressly indicated, include the Agent in its capacity as a Bank. AgStar and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, the Borrower, all as if AgStar were not the Agent hereunder and without any duty to account therefor to the Banks.

     Section 7.05. Bank Credit Decision. It is understood and agreed by each Bank that it has been, and will continue to be, solely responsible for making its own independent appraisal of and investigations into the financial condition, creditworthiness, condition, affairs, status and nature of the Borrower and the Collateral. Accordingly, each Bank confirms to the Agent that such Bank has not relied, and will not hereafter rely, on the Agent (i) to check or inquire on its behalf into the adequacy, accuracy or completeness of any information provided by the Borrower under or in connection with this Agreement, the Loan Documents or the transactions herein or therein contemplated (whether or not such information has been or is hereafter distributed to such Bank by the Agent), (ii) to assess or keep under review on its behalf the financial condition, creditworthiness, condition, affairs, status or nature of the Borrower or any Collateral provided to secure the Obligations of the Borrower under the Loan Documents, or (iii) to obtain, verify or record information that identifies the Borrower in accordance with the USA PATRIOT Act (Title III of Pub Law No. 107-56). Each Bank acknowledges that a copy of each of the Loan Documents has been made available to it and to its individual legal counsel for review and such Bank acknowledges that it is satisfied with the form and substance of the Loan Documents, and is not relying upon advice or recommendations of the Agent or the Agent’s counsel.

     Section 7.06. Indemnification. The Banks agree to indemnify the Agent (to the extent not reimbursed by the Borrower), ratably according to their Pro Rata Shares, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgment, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of the Loan Documents or the Obligations or any action taken or omitted by the Agent under this Agreement, provided that no Bank shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Agent’s gross negligence or willful misconduct. Without limiting the generality of the foregoing, each Bank agrees to reimburse the Agent promptly upon demand for any reasonable out-of-pocket expenses (including reasonable counsel fees) incurred by the Agent in connection with the preservation of any rights of the Agent or the Banks under, or the enforcement of, or legal advice in respect of rights or responsibilities under the Loan Documents to the extent that the Agent is not reimbursed for such expenses by the Borrower.

     Section 7.07. Successor Agent. The Agent may resign at any time by giving written notice thereof to the Banks and the Borrower. The Banks may appoint one of the Banks as a successor Agent; provided that, if no successor Agent shall have been appointed by the Banks, and shall have accepted such appointment, within thirty (30) days after the retiring Agent’s having given notice of resignation, then the retiring Agent may, on behalf of the Banks, appoint a successor Agent, which shall be either a Bank or a bank reasonably acceptable to the Borrower, organized under the laws of the United States or of any state thereof, or any affiliate of such bank, and having a combined capital and surplus of at least Five Hundred Million and No/100 Dollars ($500,000,000.00); provided, however, that any successor Agent, any sub Agent and any other person designated to receive payments under any Loan Document from the Borrower for the benefit of the Agent or any Bank shall be a “U.S. Person” and a “Financial Institution” as such terms are defined in Section 1.1441-1 of the Treasury Regulations. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers,

privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement. After any retiring Agent’s resignation hereunder as Agent, the provision of this Article VII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement.

     Section 7.08. Exchange of Information. Each Bank and the Agent shall freely exchange with the other Banks and/or Agent any information relating to the condition, financial or otherwise, of the Borrower, and the Borrower hereby consents to any and all prior, present or future such exchanges.

     Section 7.09. Benefit of the Banks Only. The terms and provisions of this Article VII are for the sole and exclusive benefit of the Agent and the Banks, and not for the benefit of the Borrower.

     Section 7.10. Authorized Actions. The Agent is hereby irrevocably authorized by the Banks, without any further action by any Bank, to release the Agent’s liens in Collateral: (i) if such Collateral is permitted to be sold or otherwise disposed of under Section 5.02(i); and (ii) upon termination of the Commitments, collateralization of all outstanding Letters of Credit and payment and satisfaction of all other non-contingent obligations of the Borrower under the Loan Documents.

ARTICLE VIII
MISCELLANEOUS

Except as otherwise provided herein or in any other Loan Document, no amendment or waiver of any provision of any Loan Document to which the Borrower is a party, nor any consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be agreed or consented to by the Required Banks and the Borrower, and each such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided that no amendment, waiver, or consent shall, without the consent of the Borrower and each Bank directly affected thereby, do any of the following: (i) except as provided in Section 2.13, increase the Commitment of such Bank; (ii) reduce the amount owed to such Bank or reduce the rate of interest thereon payable to such Bank, or reduce any fees payable to such Bank hereunder; (iii) extend or postpone the scheduled date of payment of any amount owed to such Bank under any Loan Document, or waive or excuse the payment thereof (but specifically excluding any amendment, modification, termination or waiver of the prepayment provisions) (provided that the Required Banks may suspend or reduce the Default Rate once it is imposed under Section 2.14); (iv) reduce the percentages specified in the definitions of “Required Banks” or “Pro Rata Share” or any provision of any of the Loan Documents regarding the Pro Rata treatment or obligations of the Banks; or (v) except as permitted by Section 7.10, release all or substantially all of the Collateral or release the Borrower or the Guarantor from liability.

Notwithstanding anything to the contrary herein, no Defaulting Bank shall have any right to approve or disapprove any amendment, waiver or consent hereunder, except that the Commitment of such Bank may not be increased or extended without the consent of such Bank.

		If to a Bank:		At the address or addresses, as the case may be, set forth on Schedule 8.02 or on the most recent Bank Supplement to which such Bank is a party.

All such notices and communications to or upon the parties hereto shall be in writing (including by telecopy) and sent to the address or facsimile number listed above and shall be effective and shall be deemed to have been duly given or made (i) when delivered in person, (ii) when transmitted via facsimile to the applicable number(s) set forth above, (iii) one Business Day following the day on which the same has been delivered prepaid (or pursuant to an invoice arrangement) to a reputable national overnight air courier service, or

(iv) the third Business Day following the day on which the same is sent by certified or registered mail, postage prepaid. Notwithstanding the other provisions of this Section 8.02, the Agent may accept oral borrowing notices, provided that the Agent shall incur no liability to the Borrower or any Bank in acting on any such communication that the Agent believes in good faith to have been given by a Person authorized to give such notice on behalf of the Borrower. Any confirmation sent by the Agent or any Bank to a Borrower of any borrowing under this Agreement shall, in the absence of manifest error, be conclusive and binding for all purposes.

     Section 8.03. No Waiver; Remedies. No failure on the part of the Agent or any Bank to exercise, and no delay in exercising, any right under any Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right under any Loan Document preclude any other or further exercise thereof or the exercise of any other right. The remedies provided in the Loan Documents are cumulative and not exclusive of any remedies provided by law.

     Section 8.04. Costs, Expenses and Taxes. The Borrower agrees to pay on demand all reasonable and documented costs and expenses of the Agent in connection with the preparation, execution, delivery, filing, recording and administration of the Loan Documents and the other related documents to be delivered under the Loan Documents, including the reasonable and documented fees and out-of-pocket expenses of counsel for the Agent, including local counsel, with respect thereto and with respect to advising the Agent as to its rights and responsibilities under the Loan Documents, and all reasonable and documented costs and expenses (including reasonable counsel fees and expenses) for the Agent in connection with the filing of the Financing Statements and, solely during the occurrence and continuation of an Event of Default, all reasonable and documented costs and expenses of the Agent and the Banks in connection with the enforcement of the Loan Documents.

     Section 8.05. Right of Set-off. Upon the occurrence and during the continuance of an Event of Default, each Bank is hereby authorized, 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 Agent and/or such Bank to or for the credit or the account of the Borrower against any and all of the Obligations, irrespective of whether or not such Bank shall have made any demand under such Loan Document and although deposits, indebtedness or such obligations may be unmatured or contingent. The Agent and each Bank, as the case may be, agrees to promptly 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 Banks under this Section are in addition to other rights and remedies (including other rights of set-off) which the Agent and the Banks may have. Each Bank agrees that for the benefit of each of the other Banks and the Agent (but not for the benefit of the Borrower) that such Bank shall not exercise any of the set-off rights described in this Section 8.05 unless such Bank had notified the Agent of such Bank’s intention to take such action and such Bank had received the Agent’s written consent to the taking of such action (unless such notice and consent requirement is waived by the Agent in its sole discretion).

     Section 8.06. 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 8.07. Binding Effect; Successors and Assigns; Participations.

          (a) This Agreement shall be binding upon and inure to the benefit of the Borrower, the Agent and the Banks and their respective successors and assigns, except that the Borrower shall have no right to assign or otherwise transfer its rights hereunder or any interest herein without the prior written consent of the Agent and the Banks, which consent shall not be unreasonably withheld or delayed. No Bank may assign, sell, participate or otherwise transfer any of its rights under the Loan Documents except as set forth in this Section 8.07.

          (b) Each Bank shall have the right at any time, with the written consent of the Agent and, unless a payment or bankruptcy Event of Default shall have occurred and be continuing, the Borrower, to assign all or portions of its rights in this Agreement or in its Commitment, participation obligations and interests, rights and security under this Agreement and any of the other Loan Documents to any other commercial, banking or financial institution, including any one or more of its Affiliates which is a commercial banking or financial institution or to one or more of the Banks (each, an “Assignee”), subject to minimum amounts of $1,600,000.00 or the remaining commitment amount if less than $1,600,000.00. Upon any such assignment, each Bank so assigning its Commitment, Advances, Notes, participation obligations and interests, rights and security under this Agreement shall pay the Agent, within two (2) Business Days of such assignment an assignment fee of $2,000.00 for its own account and shall promptly notify the Borrower, the Agent and the other Banks thereof. Each Bank so assigning its Commitment, Advances, Notes, participation obligations and interests, rights and security under this Agreement or any of the other Loan Documents shall execute and deliver, and cause such Assignee to execute and deliver, an agreement in the form of Exhibit K hereto and such other documents and instruments reasonably requested by the Agent (collectively, a “Bank Supplement”) to evidence such assignment and to substitute the Assignee as a Bank on all of the Loan Documents. The Borrower hereby acknowledges and agrees that any assignment described in this Section 8.07 will give rise to a direct obligation of the Borrower to the Assignee and such party shall be considered a Bank and rely on, and possess all rights under this Agreement or any other Loan Document. The Borrower shall accord full recognition to any such assignment, and all rights and remedies of such Bank in connection with the interest so assigned shall be as fully enforceable by such Assignee as they were by the assignor as a Bank that was a party to this Agreement on the date hereof. The Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a register for the recordation of the names and addresses of the Banks, and the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Agent and the Banks shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Bank hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Bank at any reasonable time and from time to time upon reasonable prior notice.

          (c) Each Bank shall have the right at any time, with the written consent of the Agent and, unless a payment or bankruptcy Event of Default shall have occurred and be continuing, the Borrower, to sell participations in all or any portion of its rights in this Agreement or its Commitment, Advances, Notes, participation obligations and interests, rights and security under this Agreement and any of the other Loan Documents to any other Person (each, a “Participant”); provided, however, that (i) such Bank’s obligations under the Loan Documents (including its Commitments) shall remain unchanged, (ii) such Bank shall remain solely responsible to the Borrower, the Issuer, and the Swingline Bank for the performance of such obligations, (iii) such Bank shall remain the holder of its Notes and owner of its participation or other interests in Letter of Credit Liabilities for all purposes of any Loan Document, and (iv) the Agent and the Borrower shall continue to deal solely and directly with such Bank in connection with such Bank’s rights and obligations under the Loan Documents. For the sole purpose of determining voting rights, “Banks” shall include those Persons that are members of the Farm Credit System which have acquired participation interests (not including subparticipation interests) in the Loans at any time in the minimum amount of Ten Million and

No/100 Dollars ($10,000,000.00), which have been designated by the Bank selling the participation to such Person as being accorded voting rights hereunder (the “Participant Designation”), and which are approved as such by the Agent with notification to the Borrower (the participation shall, in turn, result in a corresponding reduction in the dollar amount of voting rights of the Bank from which such participation interests were acquired). The Participant Designation shall (i) state the name and contact information of the participant as would be required of an assignee pursuant to a Bank Supplement, and (ii) state the amount of the participation purchased. The Agent shall be entitled to conclusively rely on any and all information contained in any Participant Designation delivered to it by a Bank. No other Participant shall be entitled to vote.

          (d) The Agent and any such Bank or Banks, as the case may be, may disclose to (i) any of the participants identified in Schedule 2.01 or, (ii) in connection with any proposed assignment or granting of a participation, the proposed assignee or participant any information that the Borrower or the Guarantor is required to deliver to the Agent and/or the Banks pursuant to this Agreement or the other Loan Documents, and the Borrower agrees to cooperate fully with the Agent and the Banks, as the case may be, in providing any such information to any proposed assignee or participant; provided such Participant identified on Schedule 2.01 and any such assignee or other Participant agrees to be bound by the confidentiality provisions set forth in Section 8.16.

     Section 8.08. Consent to Jurisdiction. All parties hereby submit to the jurisdiction of any Minnesota State court sitting in Blue Earth County, Minnesota, or Federal court sitting in Minneapolis, Minnesota, in any action or proceeding arising out of or relating to this Agreement or any of the other Loan Documents, and each party hereby agrees that claims in respect of such action or proceeding may be heard and determined in such Minnesota State court or in such Federal court. Each party 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.

     Section 8.09. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF MINNESOTA (WITHOUT REFERENCE TO THE CHOICE OF LAW PRINCIPLES THEREOF).

     Section 8.10. Banks’ Obligations Several, Not Joint. The obligations of the Banks under this Agreement and the other Loan Documents are several, and are not joint. No Bank or the Agent shall be responsible or liable in any way for the failure or refusal of any other Bank to make any Advance to be made by any other Bank, or for any other obligations of any other Bank.

     Section 8.11. 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 8.12. 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 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, until repayment of the Loans and Letters of Credit and termination of the Commitments. 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 Obligations, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any

provision hereof. This Agreement shall terminate on the date (the “Termination Date”) on which all Obligations then due and owing have been paid in full, all Commitments have been terminated, and all undrawn portions or Letters of Credit have been cash collateralized or otherwise provided for pursuant to arrangements satisfactory to the Issuer except that (x) those provisions which by the express terms thereof continue in effect notwithstanding the Termination Date, and (y) the Obligations in the nature of continuing indemnities not yet due and payable, shall continue in effect.

     Section 8.13. Entire Agreement. THIS AGREEMENT, THE NOTES, AND THE OTHER LOAN DOCUMENTS REFERRED TO HEREIN EMBODY THE FINAL, ENTIRE AGREEMENT AMONG THE PARTIES HERETO AND SUPERSEDE ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF.

     Section 8.14 Waiver of Borrower Rights. The Borrower acknowledges and agrees that, to the extent the provisions of the Agricultural Credit Act of 1987, including 12 U.S.C. §§ 2199 through 2202e, and the implementing Farm Credit Administration regulations, 12 C.F.R. § 617.7000, et seq. (collectively, the “Farm Credit Law”) apply to the Borrower or to the transactions contemplated by this Agreement, the Borrower hereby irrevocably waive all Borrower Rights, including all statutory or regulatory rights of a borrower to disclosure of effective interest rates, differential interest rates, review of credit decisions, distressed loan restructuring, and rights of first refusal. The Borrower acknowledges and agrees that the waiver of Borrower Rights provided by this Section 8.14 is knowingly and voluntarily made after the Borrower has consulted with legal counsel of its choice and has been represented by counsel of its choice in connection with the negotiation of this Agreement and the waiver of Borrower Rights set forth in this Section 8.14. The Borrower acknowledges that its waiver of Borrower Rights set forth in this Section 8.14 is based on its recognition that such waiver is material to induce commercial banks and other non-Farm Credit System institutions to participate in the extensions of credit contemplated by this Agreement and to provide extensions of credit to the Borrower. Nothing contained in this Section 8.14, nor the delivery to the Borrower of any summary of any rights under, or any notice pursuant to, the Farm Credit Law shall be deemed to be, or be constructed to indicate the determination or agreement by the Borrower, the Agent, or any Bank that the Farm Credit Law, or any rights thereunder, are or will be applicable to the Borrower or to the transactions contemplated by this Agreement. It is the intent of the Borrower that the waiver of Borrower Rights contained in this Section 8.14 complies with and meets all of the requirements of 12 C.F.R. § 617.7010(c).

     Section 8.15. WAIVER OF JURY TRIAL. EACH OF THE BORROWER, THE AGENT AND THE BANKS HEREBY IRREVOCABLY WAIVES ALL RIGHT 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.

     Section 8.16. Confidentiality. Each of the Agent and each Bank agrees to exercise reasonable care to protect against the unauthorized disclosure of information provided to it by the Borrower or the Guarantor pursuant to the Loan Documents; provided that the Agent or any Bank is hereby authorized to disclose such Confidential information:

          (a) as authorized or required by federal or state laws, regulations, ordinances or rules;

          (b) to the Agent, any other Bank or any Affiliate of any Bank,

          (c) to any third party that provides services to the Agent or the Bank for processing or storing information related to loans subject to a written agreement pursuant to which the third party agrees to protect against the unauthorized disclosure of information provided by the Agent or the Bank,

          (d) to any Assignee or Participant or prospective Assignee or Participant that has agreed to protect the confidentiality of information received from the Agent or any Bank,

          (e) to its employees, directors, agents, attorneys, accountants and other professional advisors or those of any of its Affiliates ,

          (f) if requested or required to do so in connection with any litigation or similar proceeding, provided that to the extent permitted by law Agent or Bank agrees to use reasonable effort to provide notice of such request within a reasonable time after providing such information,

          (g) that has been publicly disclosed other than in breach of this Section 8.16, or

          (h) in connection with the exercise of any remedy hereunder or under any other Loan Document.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their respective duly authorized officers, as of the date first above written.
