PROMISSORY NOTE/LOAN AGREEMENT (Adjustable Rate Term Loan — LIBOR Based)

(Adjustable Rate Term Loan — LIBOR Based)

June 20, 2002

This note is made pursuant to and subject to the provisions of the most recent Basic Membership and Lending Relationship Agreement between the parties.

For value received, the undersigned jointly and severally promise to pay to the order of AgCountry Farm Credit Services, PCA (the “Lender”), a federally chartered corporation, at its office in Fargo, North Dakota, the principal sum of $2,000,000.00, together with interest on the whole amount of said principal sum remaining from time to time unpaid. The indebtedness shall bear interest at the initial rate of 4.98 percent per annum. On the first day of each month the interest rate shall be adjusted by adding a margin of 3.14 percentage points to the index. This margin shall remain in effect until the first day of June, 2003, at which time Lender may change the margin at its discretion, and Lender may continue to change the margin at successive intervals of one year(s) each thereafter. The index for adjustments is the One Month London Interbank Offered Rate (“One Month LIBOR”) reported on the tenth day of the month preceding the interest rate change date by the Wall Street Journal in its daily listing of money rates defined therein as “the average of Interbank offered rates for dollar deposits in the London market based on quotations at five major banks.” If a One Month LIBOR rate is not reported on the tenth day of a month, the One Month LIBOR rate reported on the first business day preceding the tenth day of the month will be used. If this index is no longer available, Lender will select a new index which is based upon comparable information.

Repayment shall be as follows (check and complete one)

o (Equal Payments) Principal is payable on an amortization plan in equal installments of $ each, unless the same are more or less by reason of adjustment(s) in the interest rate as aforesaid, beginning on the first day of , , and thereafter, and a final installment of the balance of principal and interest remaining unpaid is payable on the first day of , , unless this note shall mature prior thereto by reason of advance payments of principal.

ý (Decreasing Payments) Principal is payable on an amortization plan in three equal installments of $500,000.00 each, beginning on the first day of June, 2004, and semi-annually thereafter, and a final installment of the balance of principal remaining unpaid is payable on the first day of December, 2005, unless this note shall mature prior thereto by reason of advance payments of principal; and interest is payable in addition to principal on the maturity dates of said principal installments.

Interest begins on the date(s) loan fund are disbursed and may be calculated based upon a 360- or 365-day year, as the Lender may determine. If the period of time from the day interest begins to the due date of the first installment is more than the interval between installments, there will be an interest only payment due one installment interval prior to the due date of the first installment, but if such period is less than the interval between installments and principal in interest are payable in equal installments, then the first installment shall be decreased by the amount of

interest not yet accrued for that installment. The undersigned may make advance payments in any amount and at any time without penalty. Prepayments shall, at the option of the Lender, (a) be held by the Lender and then applied to installments of principal and interest next scheduled to mature in the order of maturity; (b) be immediately applied to payment of principal then outstanding, resulting in a reamortizaiton of the remaining balance of the loan over the remaining term under the existing payment plan and in a corresponding reduction in the amount of future installments of principal and interest, or (c) be immediately applied to payment of principal then outstanding, with a corresponding reduction in the number of future installments of principal and interest in the inverse order of maturity, thus discharging the loan at an earlier date; provided, in any event, the Lender may, at its option, first apply any such prepayment to the payment of interest accrued to the date of prepayment.

Upon failure to make any payment of either principal or interest when due or to repay any advancements made under the terms of the security instruments securing payment of this note or upon failure to comply with any of the covenants, conditions or agreements contained in this note, including any addendum attached hereto, or upon default under the provisions of the Basic Membership and Lending Relationship Agreement, then, at the option of the Lender, without presentment or demand, the entire indebtedness, including all principal, interest and advancements, shall at once become due and payable. Prior to maturity, in the event of such default, the entire unpaid principal balance and all advancements shall bear interest from the date of default until such default is cured or the indebtedness is accelerated by reason of default at the rate of rates equal to the interest rate or rates for this loan that would otherwise be in effect during the period of default plus 2.00 percent per annum (the “default rate”), and the amount of such interest in excess of interest otherwise accruing in the absence of default shall be immediately due and payable. At maturity or in the event of acceleration as aforesaid, then the entire indebtedness, including all principal, interest and advancements, shall bear interest until paid at the default rate in effect at the time of maturity or acceleration, as the case may be. In the event that the undersigned fails to perform any of the agreements contained in this note, or if any action or proceeding is commenced which materially affects the Lender’s interest, including but not limited to eminent domain, insolvency, bankruptcy, code enforcement or probate, then the Lender at its option may make such appearances, disburse such sums and take such action as it deems necessary to protect its interest, including but not limited to, disbursement of reasonable attorneys’ fees. Any amounts so disbursed by Lender shall become additional principal, due as incurred, and in the event of foreclosure or any action to collect on this note, be included in the judgment to the extent not prohibited by applicable law.

The undersigned (“Borrower”), all of whom are makers, together with all endorsers, sureties and guarantors of this note, hereby waive presentment, notice of nonpayment, demand, protest and notice of protest, and diligence in enforcing payment hereof, consent to the extension of time for payment of any installment or other payment due hereunder from time to time without notice and to the reamortization of the indebtedness evidenced hereby from time to time without notice, and waive all defenses or right of offset which they or any of them may or might have against the Lender.

As used herein, “Lender” shall mean the Lender named above and its successors and assigns as the holder of this note, and “Bank” shall include AgriBank, FCB and its successors, provided the Lender may not assign or otherwise transfer this note to any party other than the Bank, whether absolutely or as collateral security, without the express written consent of the Bank. If this note is assigned or otherwise transferred to the Bank or another institution

chartered pursuant to the provisions of the Act, the interest rate hereunder may be established by such institution in accordance with the provisions of this note and related loan documents; however, notwithstanding any provision hereof to the contrary, upon an assignment or transfer to any other party note chartered under the Act, in the absence of maturity or acceleration as provided herein, the margin that is used for interest rate adjustments shall remain fixed for the remaining term of the loan at the margin amount that is in effect at the term of the assignment.

Payment of the obligation evidence by this note is secured by the mortgage(s) or deed(s) of trust dated June 20, 2002, conveying real estate in the county or counties of , State or States of .. This obligation is also secured by the security agreement(s) dated , as amended from time to time; or

ý If this box is checked, by all existing and future security agreements from all or any of the Borrowers (and from third parties if so intended) to the Lender.

o All of the covenants and agreements contained in said security instruments are made a part of this note.

PROMISSORY NOTE/LOAN AGREEMENT

ADDITIONAL PROVISIONS

INDIVIDUAL LOAN PRICING PROGRAM: The Program provides for charging differential interest rates according to loan classes determined by criteria adopted by the Lender from time to time, such as type of loan, purpose, amount, quality, funding costs, operating costs, servicing costs, and competitive interest rates. These are separate types of loans and interest rates under the Program, each having a different rate of interest, and the loans within each class are assigned to an interest rate category. It is possible that the particular rate for each class of loan may differ among such geographical areas as may be designated from time to time. In the event that Borrowers default under the terms or conditions of any promissory note, membership agreement, mortgage or other security document, or any amendatory agreement to any of these, the Lender at its option may adjust this loan to any less favorable interest rate category then offered or maintained by Lender for loans of this type. The higher interest rate shall become effective immediately upon placement of this loan into the less favorable interest rate category by Lender, and the loan may, at the option of Lender, remain in the less favorable interest rate category for the remaining term of the loan, regardless of whether Borrowers later cure the default. Lender shall not place the loan into a less favorable interest rate category unless Lender has first given Borrowers written notice of the default, and Borrowers fail to cure the default within 60 days after Lender has given the notice. Notice shall be deemed to have been given when Lender places such notice in the mail for first-class mailing to the last address of Borrowers known by Lender in addition to adjusting the loan to a less favorable interest rate category, Lender may also charge the higher default interest rate described below.

INTEREST RATE: If this is a:

(a) Variable Rate loan, the initial annual rate of interest is equal to the Stated Interest Rate. The interest rate is subject to change at any time and by any amount during the term of the loan and will vary from time to time at the option of the Lender.

(b) Fixed Rate loan, the annual rate of interest is equal to the Stated Interest Rate. The interest rate is not subject to change during the term of the loan and will not be increased or decreased except in the event of default.

(c) Adjustable Rate Operating RLOC, the initial annual rate of interest is equal to the Stated Interest Rate. The interest rate is subject to change at any time and by any amount during the term of the loan, but only and after the first adjustment date, and the rate will not be increased or decreased prior to that date except in the event of default.

(d) Adjustable Rate loan or an Adjustable Rate IT loan or an Adjustable Rate Capital RLOC, the initial annual rate of interest is equal to the Stated Interest Rate. The interest rate is subject to change by any amount during the term of the loan, but only on the first adjustment date and on dates occurring at the end of the successive adjustment intervals thereafter, and the rate will not be increased or decreased during any one such interval except in the event of default.

(e) Adjustable Rate Prime Rate Based loan, the initial annual rate of interest is equal to the Stated Interest Rate. The index for adjustments is the prime rate reported on the tenth day of the month preceding the interest rate change date by the Wall Street Journal, in its daily listing of money rate, defined therein as “the base rate on corporate loans posted by at least 75 percent of the nation’s 30 largest banks.” If a prime rate is not reported on the tenth day of a

month, the prime rate reported on the first business day preceding the tenth day of the month will be used. If this index is no longer available, Lender will select a new index which is based upon comparable information.

(f) Capped Non-indexed Variable Rate loan, the initial annual rate of interest is equal to the Stated Interest Rate. The interest rate is subject to change at any time and will vary from time to time at the option of the Lender. The interest rate is not based on an index. Except during periods of default when the additional percentage points specified herein shall be added to increase the interest rate, the interest rate may not increase or decrease by more than 6.00 percentage points above or below the initial annual rate of interest on any single change date or during the term of the Loan.

(g) Fixed Then Indexed Adjustable Rate loan, the initial annual rate of interest is equal to the Stated Interest Rate. Once the interest rate changes to an adjustable interest rate at the end of the fixed interest rate period, the index for adjustments is the estimated weekly average for one-year bonds funding cost index as reported by the Federal Farm Credit Banks Funding Corporation at its Web site, found in the Publications and Archives section at http:/xxx.xxxxxxxxxx-xxxx.xxx. for that week which contains the date that is 45 days before the date that the adjustable interest rate is to be initially determined or subsequently adjusted. If the date that is 45 days before either the expiration date of the fixed interest rate period or an Adjustment Interval is not a business day, the Lender shall use that estimated weekly average for one-year bonds funding cost index of that week which includes that business day which immediately precedes the 45-day date. If this index is no longer available, the Lender will select a new index which is based on comparable information. The Lender will give the Borrower notice of this choice.

(h) Indexed Adjustable Rate loan, the initial annual rate of interest is equal to the Stated Interest Rate. The index for adjustments is the estimated weekly average for on-year bonds funding cost index as reported by the Federal Farm Credit Banks Funding Corporation at its Web site, found in the Publications and Archives section at xxxx://xxx.xxxxxxxxxx-xxxx.xxx, for that week which contains the date that is 45 days before a date the interest rate is to be adjusted. If the date that is 45 days before a date the interest rate is to be adjusted is not a business day, the Lender shall use that estimated weekly average for one-year bonds funding cost index for that week which includes that business day which immediately proceeds the 45-day date. If this index is no longer available, the Lender will select a new index which is based on comparable information. The Lender will give the Borrower notice of this choice.

(i) Adjustable Rate LIBOR based loan, the initial annual rate of interest is equal to the Stated Interest Rate. The index for adjustments is the One Month London Interbank Offered Rate (“One Month LIBOR”) reported on the tenth day of the month preceding the interest rate change date by the Wall Street Journal in its daily listing of money rates, defined therein as the average interbank offered rates for dollar deposits in the London market based on quotations at five major banks. If a One Month LIBOR rate is not reported on the tenth day of a month, the One Month LIBOR rate reported on the first business day preceding the tenth day of the month will be used. If this index is no longer available, Lender will select a new index which is based upon comparable information.

Interest may be based upon a 360-or-365-day year as the Lender may determine.

DEFAULT RATE OF INTEREST: Prior to maturity, if Borrowers default under this document, the entire unpaid principal balance of the loan, including all advancements, shall bear

interest from the date of default until the default is cured or maturity of the loan is accelerated by reason of default at a rate equal to the interest rate for this loan that would otherwise be in effect during the period of default plus the Default Add-On Rate per annum (the “default rate”), and the amount of such interest in excess of interest otherwise occurring in the absence of default shall be immediately due and payable. At maturity or upon acceleration of maturity by reason of default, the entire indebtedness including all principal, interest and advancements shall bear interest until paid at the default rate in effect at the time of maturity or acceleration of maturity, as the case may be.

DISBURSEMENTS OF PRINCIPAL: Disbursements of principal may be made at various times at Borrowers’ request, subject to the provisions of this paragraph, Repayments of principal under a Revolving Line of Credit reinstate the loan commitment, subject to the terms of this document, but the total of the unpaid balance of future advances together with the existing indebtedness hereunder, in the aggregate at any one time outstanding, shall not exceed the Loan Amount; otherwise, repayments of principal do not reinstate the loan commitment, and total disbursements, in the aggregate shall not exceed the Loan Amount. The Lender may withhold further disbursements if it determines that: (a) the value of the Collateral is insufficient; (b) loan proceeds have been used for purposes not approved by the Lender; (c) loan payments have not been made in accordance with the repayment plan contained in the loan application; or (d) an event has occurred which entitles the Lender to accelerate maturity of the loan.

DRAFT PROGRAM AGREEMENT: If the Draft Program is applicable to this loan, the Borrowers may draw loan funds using the draft forms furnished by the Lender, subject to the following terms and conditions:

(a) The Borrowers authorize and direct the Lender and its duly authorized agents to accept drafts made or drawn by any one of the Borrowers and to disburse loan funds accordingly, as specified in this document. The Borrowers may be charged a reasonable fee for this program and the cost of printing drafts.

(b) The Borrowers jointly and severally accept responsibility for all disbursements made pursuant to this authorization and direction. The Lender shall not be obligated to inquire as to whether the Borrowers have issued specific directions for any particular draft or to determine whether the Borrowers have received the benefit of the proceeds of any particular draft before honoring such draft. Drafts may be deposited directly into the bank account of any one of the Borrowers.

(c) The minimum amount for which each draft may be written is the Minimum Draft amount. In the event that Borrowers write any draft for an amount below this minimum, the Lender may charge Borrowers a reasonable fee for each draft that is not in compliance.

(d) Drafts may not be written in excess of the undisbursed loan commitment. The Lender reserves the right to revoke all future draft privileges without notice to the Borrowers in the event of an overdraft and the right to reject drafts that are not written for purposes specified in the loan documents or pursuant to these terms and conditions. In the event that Lender chooses to honor a draft which exceeds the available loan commitment, Borrowers are liable for full repayment of the funds thus borrowed, plus interest, and Lender may charge Borrowers a reasonable overdraft fee.

(e) The Borrowers agree to immediately notify the Lender in the event one or more drafts are lost, stolen, destroyed or otherwise misused and to indemnify the Lender and hold the

Lender harmless from any loss or claim if any draft is lost, stolen, forged, altered or otherwise misused if the Lender did not have notice of the same at least 24 hours prior to honoring such draft.

(f) The Borrowers may stop payment on a draft by request to the Lender. The Borrowers will be charged a reasonable fee for each stop-payment order and agree to reimburse the Lender for all damages, costs and expenses as a result of the Lender’s refusal to honor such draft. The Lender shall not be liable in the event the draft is honored following a stop-payment order if such order is not received in sufficient time to permit dishonor.

(g) This authorization and direction shall be effective as to this and, with the Lender’s approval, other existing and future loans to the Borrowers and shall continue in force and effect until the Lender receives written notice of revocation signed by the Borrowers, provided the privilege of using drafts may be withdrawn by the Lender and unused drafts must be surrendered to the Lender on demand.

FUNDS HELD PROGRAM: Lender may offer a Funds Held Program (“Program”) that allows Borrowers to make advance conditional payments on designated loans. Lender reserves the right, in its discretion, to amend or terminate the Program. The following terms and conditions apply to all Program accounts in connection with loans from Lender.

(a) Subject to Lender’s rights to direct the application of payments, an advance payment made to be applied to future maturities on a loan will be placed in a Program account (“Account”) as of the date received. If a special prepayment of principal is desired, Borrowers must so specify when an advance payment is made.

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

(c) When a loan installment or other related charge becomes due, funds in the Account for that loan will be automatically applied on the due date toward payment of the Installment or related charge. Any accrued interest in the Account will be applied first. If the funds in the Account are not adequate to pay the entire installment or related charge, Borrowers must pay the difference by the installment due date.

(d) Funds received after a loan installment or related charge has been billed will be applied to the installment or related charge due. Funds received in excess of the billed installment amount or related charge will be placed in the Account.

Even though no installment or related charge is due, Lender may, at its option, apply funds from the Account without notice to Borrowers as follows:

- Protective Advances. If Borrowers fail to pay when due other items Borrowers are required to pay pursuant to any loan document, Lender may apply funds in the Account to pay them.

- Account Calling. If the Account balance exceeds the unpaid balance on the loan, Lender may apply the funds in the Account to pay off the loan and will return any excess funds.

- Transfer of Security. If Borrowers sell, assign, or transfer any interest in any collateral for the loan, Lender may apply the funds in the Account to the remaining loan balance.

- Deceased Borrowers. If all Borrowers are deceased, Lender may apply the funds in the Account to the remaining loan balance.

- Termination of Program. If Lender decides to terminate the Program, it may apply all funds in the Account to the remaining loan balance effective on the termination date.

(e) Lender may, in its discretion, permit Borrowers to withdraw funds from the Account in accordance with Lender’s Program.

(f) Neither the advance payments nor the accrued interest in an Account are insured by a governmental agency or instrumentally. If Lender is placed in liquidation, Borrowers shall be sent by the receiver such notices as required by FCA regulations then in effect. Such regulations currently provide for advance notice from the receiver that funds in the Account will be applied to the loan and that funds in the Account will not earn interest after the receiver is appointed.

LOAN PAYMENTS: If the loan is payable in installments and the period from the day interest begins to the due date of the first installment is more than the interval between installments, there may be an interest only payment due one installment interval prior to the due date of the first installment, or the interest may be included in the first installment at the option of the Lender, but if such period is less than the interval between installments and principal and interest are payable in equal installments, then the first installment will be decreased by the amount of interest not yet accrued for that installment. The final installment may be more or less than preceding installments, if any, and any periodic adjustments to the interest rate will result in corresponding changes in the amount of installments, if the loan is payable in installments, or the amount due at maturity. The Borrowers may make advance payments in any amount and at any time without penalty. Prepayments shall, at the option of the Lender, (a) be held by the Lender and then applied to installments of principal and interest next scheduled to mature in the order of maturity, (b) be immediately applied to payment of principal then outstanding, resulting in a reamortization of the remaining balance of the loan over the remaining term under the existing payment plan and in a corresponding reduction in the amount of future installments of principal and interest, or (c) be immediately applied to payment of principal then outstanding, with, if an amortized loan, a corresponding reduction in the number of future installments of principal and interest in the inverse order of maturity, thus discharging the loan at an earlier date; provided, in any event, the Lender may, at its option, first apply any such prepayments to the payment of interest accrued to the date of prepayment.

PERSONAL PROPERTY AND FIXTURES: The following subsections (1) and (2) including the definitions apply, in addition, only if the collateral described on Promissory Note/Loan Agreement, and each addendum thereto, is personal property or fixtures:

(5) After deduction of expenses, the Lender may apply the proceeds of disposition to the Obligations in the order and amounts it elects.

ASSIGNMENT OF LOAN: The Lender may not assign or otherwise transfer this loan to any party other than AgriBank, FCB and its successors (the “Bank”), whether absolutely or as collateral security and whether in the ordinary course of business or otherwise, without the express written consent of the Bank. If this loan is assigned or otherwise transferred to the Bank or another institution chartered pursuant to the provisions of the Farm Credit Act of 1971, as amended, (“Act”) the interest rate hereunder may be established by such institution in accordance with the provisions of this document. If this loan is assigned or transferred to a party not chartered under the Act, notwithstanding any contrary provision in this document, in the absence of maturity or acceleration, the following apply:

(a) If this is a Variable Rate loan or an Adjustable Rate Operating RLOC, adjustment in the interest rate will be made only on the dates occurring at successive intervals of one year each after the first day of the month and year of such assignment based upon an index and margin.

The index will be the same as for a Variable Rate Loan, except it will be adjusted to a constant maturity of a length equal to the length of the interval between adjustments specified above (if U.S. Treasury yield figures are not available for this length, the U.S. Treasury yield figures which are available for the closest length of time which is shorter than the interval between adjustments will be used).

(c) For interest rate adjustments under (a) and (b), the margin will be the amount by which the interest rate in effect for this loan at the time of the assignment, in the absence of default, exceeds the index that would have been effective for the date that this interest rate was established for this loan (the last previous repricing date). The new interest rate will calculated by adding the margin to the applicable current index and rounding the total to the nearest one-eighth of one percent, subject however, to the provision herein for a higher default rate. The current index will be the most recent index available as of 45 days before the date the interest rate is to be adjusted. If the applicable index is not available, the Lender will select a new index which is based upon comparable information. The interest rate shall never exceed the rate permitted by applicable law.

(d) If this is an Adjustable Rate Prime Rate Based loan, the margin that is used for interest rate adjustments shall remain fixed for the remaining term of the loan at the margin amount that is in effect at the time of the assignment.
