THIS MASTER LOAN AGREEMENT is entered into as of March 31, 2000, between CoBANK, ACB ("CoBank", successor by merger to the St. Paul Bank for Cooperatives) and AMERICAN CRYSTAL SUGAR COMPANY, Moorhead, Minnesota (the "Company").

On March 5, 1999, the St. Paul Bank for Cooperatives ("SPB") entered into a Seasonal Loan Agreement (the "Seasonal Loan Agreement") and a Term Loan Agreement (the "Term Loan Agreement") (collectively, the "Existing Loan Agreements") with the Company. Under the Seasonal Loan Agreement, SPB made various seasonal loans to the Company, each of which was evidenced by a promissory note. Under the Term Loan Agreement, SPB made various term loans, each of which was also evidenced by a promissory note. Subsequently, SPB merged with and into CoBank. CoBank and the Company now desire to amend and restate the Existing Loan Agreements and consolidate the Existing Loan Agreements into this Master Loan Agreement. CoBank and the Company also desire to amend and restate the promissory notes evidencing the seasonal loans and term loans made pursuant to the Existing Loan Agreements by entering into various Supplements in place of the promissory notes. Each Supplement will set forth the amount of the loan, the purpose of the loan, the interest rate or rate options applicable to that loan, the repayment terms of the loan, and any other terms and conditions applicable to that particular loan. Each loan will be governed by the terms and conditions contained in this Master Loan Agreement and in the Supplement relating to the loan. Collateral securing loans made pursuant to the Existing Loan Agreements shall continue to secure those same loans, all as now evidenced by various Supplements, to the same extent as provided for in the Existing Loan Agreements and any security agreements (including, without limitation, mortgages and deeds of trust) entered into in connection therewith.

SECTION 1. Supplements. In addition to those Supplements entered into to amend and restate the promissory notes executed in connection with the Existing Loan Agreements, the parties may enter into other Supplements in order to evidence new loans that CoBank may make to the Company. Each Supplement will set forth the amount of the loan, the purpose of the loan, the interest rate or rate options applicable to that loan, the repayment terms of the loan, and any other terms and conditions applicable to that particular loan. Each loan will be governed by the terms and conditions contained in this Master Loan Agreement and in the Supplement relating to the loan.

SECTION 2. Availability. Loans will be made available on any day on which CoBank and the Federal Reserve Banks are open for business upon the telephonic or written request of the Company. Requests for loans must be received no later than 12:00 noon Company's local time on the date the loan is desired. Loans will be made available by wire transfer of immediately available funds to such account or accounts as may be authorized by the Company. The Company shall furnish to CoBank a duly completed and executed copy of a CoBank Delegation and Wire and Electronic Transfer Authorization Form, and CoBank shall be entitled to rely on (and shall incur no liability to the Company in acting on) any request or direction furnished in accordance with the terms thereof.

SECTION 3. Repayment. The Company's obligation to repay each loan shall be evidenced by the promissory note set forth in the Supplement relating to that loan or by such replacement note as CoBank shall require. CoBank shall maintain a record of all loans, the interest accrued thereon, and all payments made with respect thereto, and such record shall, absent proof of manifest error, be conclusive evidence of the outstanding principal and interest on the loans. All payments shall be made by wire transfer of immediately available funds or by check. Wire transfers shall be made to ABA No. 307088754 for advice to and credit of CoBANK (or to such other account as CoBank may direct by notice). The Company shall

give CoBank telephonic notice no later than 12:00 noon Company's local time of its intent to pay by wire and funds received after 3:00 p.m. Company's local time shall be credited on the next business day. Checks shall be mailed to CoBank, Department 167, Denver, Colorado, 80291-0167 (or to such other place as CoBank may direct by notice).

However, the maximum amount of equity which the Company shall be obligated to purchase in connection with any loan may not exceed the maximum amount permitted by the Bylaws at the time the Supplement relating to that loan is entered into or such loan is renewed or refinanced by CoBank.

SECTION 5. Security.

In addition, upon the occurrence and during the continuance of any Event of Default, CoBank may, upon notice to the Company, terminate any commitment and declare the entire unpaid principal balance of the loans, all accrued interest thereon, and all other amounts payable under this agreement, all Supplements, and the other Loan Documents to be immediately due and payable. Upon such a declaration, the unpaid principal balance of the loans and all such other amounts shall become immediately due and payable, without protest, presentment, demand, or further notice of any kind, all of which are hereby expressly waived by the Company. In addition, upon such an acceleration:

(A) Enforcement. CoBank may proceed to protect, exercise, and enforce such rights and remedies as may be provided by this agreement, any other Loan Document or under Law. Each and every one of such rights and remedies shall be cumulative and may be exercised from time to time, and no failure on the part of CoBank to exercise, and no delay in exercising, any right or remedy shall operate as a waiver thereof, and no single or partial exercise of any right or remedy shall preclude any other or future exercise thereof, or the exercise of any other right. Without limiting the foregoing, CoBank may hold and/or set off and apply against the Company's obligations to CoBank the proceeds of any equity in CoBank, any cash collateral held by CoBank, or any balances held by CoBank for the Company's account (whether or not such balances are then due).

(B) Application of Funds. CoBank may apply all payments received by it to the Company's obligations to CoBank in such order and manner as CoBank may elect in its sole discretion.

In addition to the rights and remedies set forth above: (i) if the Company fails to purchase any equity in CoBank when required or fails to make any payment to CoBank when due, then at CoBank's option in each instance, such payment shall bear interest from the date due to the date paid at 4% per annum in excess of the rate(s) of interest that would otherwise be in effect on that loan; and (ii) after the maturity of any loan (whether as a result of acceleration or otherwise), the unpaid principal balance of such loan (including without limitation, principal, interest, fees and expenses) shall automatically bear interest at 4% per annum in excess of the rate(s) of interest that would otherwise be in effect on that loan. All interest provided for herein shall be payable on demand and shall be calculated on the basis of a year consisting of 360 days.

SECTION 13. Broken Funding Surcharge. Notwithstanding any provision contained in any Supplement giving the Company the right to repay any loan prior to the date it would otherwise be due and payable, the Company agrees that in the event it repays any fixed rate balance prior to its scheduled due date or prior to the last day of the fixed rate period applicable thereto (whether such payment is made voluntarily, as a result of an acceleration, or otherwise), the Company will pay to CoBank a surcharge in an amount which would result in CoBank being made whole (on a present value basis) for the actual or imputed funding losses incurred by CoBank as a result thereof. Notwithstanding the foregoing, in the event any fixed rate balance is repaid as a result of the Company refinancing the loan with another lender or by other means, then in lieu of the foregoing, the Company shall pay to CoBank a surcharge in an amount sufficient (on a present value basis) to enable CoBank to maintain the yield it would have earned during the fixed rate period on the amount repaid. Such surcharges will be calculated in accordance with methodology established by CoBank (a copy of which will be made available to the Company upon request).

SECTION 14. Complete Agreement, Amendments. This agreement, all Supplements, and all other instruments and documents contemplated hereby and thereby, are intended by the parties to be a complete and final expression of their agreement. No amendment, modification, or waiver of any provision hereof or thereof, and no consent to any departure by the Company herefrom or therefrom, shall be effective unless approved by CoBank and contained in a writing signed by or on behalf of CoBank, and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. In the event this agreement is amended or restated, each such amendment or restatement shall be applicable to all Supplements hereto.

SECTION 15. Other Types of Credit. From time to time, CoBank may issue letters of credit or extend other types of credit to or for the account of the Company. In the event the parties desire to do so under the terms of this agreement, such extensions of credit may be set forth in any Supplement hereto and this agreement shall be applicable thereto.

SECTION 16. Applicable Law. Except to the extent governed by applicable federal law, this agreement and each Supplement shall be governed by and construed in accordance with the laws of the State of Colorado, without reference to choice of law doctrine.

SECTION 17. Notices. All notices hereunder shall be in writing and shall be deemed to be duly given upon delivery if personally delivered or sent by telegram or facsimile transmission, or 3 days after mailing if sent by express, certified or registered mail, to the parties at the following addresses (or such other address for a party as shall be specified by like notice):

SECTION 21. Participations. From time to time, CoBank may sell to one or more banks or other financial institutions a participation in one or more of the loans or other extensions of credit made

THIS SUPPLEMENT to the Master Loan Agreement dated March 31, 2000 (the "MLA"), is entered into as of April 21, 2000, between CoBANK, ACB ("CoBank") and AMERICAN CRYSTAL SUGAR COMPANY, Moorhead, Minnesota (the "Company"), and amends and restates the Supplement dated March 31, 2000 and numbered Z269S01.

SECTION 1. The Revolving Credit Facility. On the terms and conditions set forth in the MLA and this Supplement, CoBank agrees to make loans to the Company during the period set forth below in an aggregate principal amount not to exceed, at any one time outstanding, the lesser of the "Borrowing Base" (as calculated pursuant to the Borrowing Base Certificate, the form of which is attached hereto as Exhibit A) or $210,000,000.00 (the "Commitment"). Within the limits of the Commitment, but subject to the Borrowing Base, the Company may borrow, repay and reborrow.

SECTION 2. Purpose and Transfer. The purpose of the Commitment is to finance the Company's general corporate purposes, fund working capital requirements, back the Company's commercial paper program, issue short-term commercial and standby letters of credit, and to renew, extend, and refinance the Company's obligations to CoBank under the Company's existing seasonal loan pursuant to Note No. 29590 (the "Existing Seasonal Loan") and the existing letter of credit commitment pursuant to Note No. 30812 (the Existing LC Commitment") (collectively, the "Notes"), both executed pursuant to the Seasonal Loan Agreement dated March 5, 1999 (the "Existing Agreement"). The Company agrees that on the date when all conditions precedent to CoBank's obligation to extend credit hereunder have been satisfied: (a) the principal balance outstanding under the Existing Seasonal Loan shall be transferred to and charged against the Commitment; (b) all accrued obligations of the Company under the Existing Seasonal Loan and the Existing LC Commitment for the payment of interest or other charges shall be transferred to and become part of the Company's obligations under this Supplement as if fully set forth herein; and, (c) the Notes and the Existing Agreement shall be deemed replaced and superseded.

SECTION 3. Term. The term of the Commitment shall be from the date hereof, up to but not including March 30, 2001, or such later date as CoBank may, in its sole discretion, authorize in writing.

SECTION 4. Interest. The Company agrees to pay interest on the unpaid balance of the loans in accordance with one or more of the following interest rate options, as selected by the Company:

(A) Base Rate Option. At a rate per annum at all times equal to the Base Rate. For the purposes hereof, Base Rate means that rate in effect from day to day defined as the "prime" rate as published from time to time in the Eastern Edition of The Wall Street Journal as the average prime lending rate for seventy-five percent (75%) of the United States; thirty (30) largest commercial banks, or if The Wall Street Journal shall cease publication or cease publishing the "prime rate" on a regular basis, such other regularly published average prime rate applicable to such commercial banks as is acceptable to the Lender in its reasonable discretion. Loans for which the Base Rate option is selected are referred to herein as "Base Rate Loans".

Base Rate Loans shall be: (a) in minimum amounts of $5,000,000 and incremental multiples of $1,000,000; and (b) made available on any Banking Day. Interest on Base Rate Loans shall be calculated on the actual number of days each loan is outstanding on the basis of a year consisting of 360 days and shall be payable monthly in arrears on the twentieth Banking Day of the following month.

(B) Quoted Rate Option. At a fixed rate per annum at all times equal to the Quoted Rate. For the purposes hereof, Quoted Rate means a fixed rate of interest to apply to a loan (referred to herein as a "Quoted Rate Loan") for a specified period of time not to exceed thirty (30) days quoted by CoBank in its sole discretion.

Quoted Rate Loans shall be (i) in minimum amounts of $1,000,000 and incremental multiples of $1,000,000; and (ii) made available on any Banking Day. The Quoted Rate may not necessarily be the lowest rate at which CoBank funds at that time.

Interest on Quoted Rate Loans shall be calculated on the actual number of days each loan is outstanding on the basis of a year consisting of 360 days and shall be payable monthly in arrears on the twentieth Banking Day of the following month.

(C) LIBOR Option. At a fixed rate equal to LIBOR plus the Applicable Margin (as defined below). For the purposes hereof, LIBOR means the rate for deposits in U.S. Dollars, with maturities comparable to the selected LIBOR Interest Period, that appears on the display designed as page "3750" of the Telerate Service (or such other page as may replace the 3750 page of that service of if the Telerate Service shall cease displaying such rates, such other service or services as may be nominated by the British Bankers' Association for the purpose of displaying London Interbank Offered Rates for U.S. Dollar deposits), determined as of 11:00 a.m. London time two Banking Days prior to the commencement of such LIBOR Interest Period. "LIBOR Interest Period" means a period of one, two, three or six months. LIBOR pricing will be adjusted for Regulation D reserve requirements. The Applicable Margin is 70 basis points. Loans for which the LIBOR option is selected are referred to herein as "LIBOR Loans".

LIBOR Loans shall be: (a) in a minimum amount of $5,000,000 and incremental multiples of $1,000,000; (b) made available on three Banking Days prior notice; and (c) be for periods of one, two, three, or six months. Interest on LIBOR Loans shall be calculated on the actual number of days each loan is outstanding on the basis of a year consisting of 360 days and shall be payable in arrears upon maturity of the applicable LIBOR Interest Period, but no less frequently than quarterly. The LIBOR option shall be subject to the following limitations:

The Company shall select the applicable rate option at the time it requests a loan hereunder and may, subject to the limitations set forth above, elect to convert balances bearing interest at the variable rate option to one of the fixed rate options. Upon the expiration of any fixed rate period, interest shall automatically accrue at the Base Rate unless the amount fixed is repaid or fixed for an additional period in accordance with the terms hereof. Notwithstanding the foregoing, unless CoBank otherwise consents in its sole discretion in each instance, rates may not be fixed for periods expiring after the maturity date of the loan. In the event CoBank so consents and the Commitment is not renewed, then each balance so fixed shall be due and payable on the last day of its fixed rate period, and the promissory note set forth below shall be deemed amended accordingly. All elections provided for herein shall be made telephonically or in writing and must be received by 12:00 noon Company's local time. As used in this Section 4, "Banking Day" means a day on which CoBank is open for business, dealings in U.S. dollar deposits are being carried out in the London interbank market, and banks are open for business in New York City and London, England

SECTION 5. Promissory Note. The Company promises to repay the unpaid principal balance of the loans on the first CoBank business day following the last day of the term of the Commitment. In addition to the above, the Company promises to pay interest on the unpaid principal balance of the loans at the times and in accordance with the provisions set forth in Section 4 hereof. This note replaces and supersedes, but does not constitute payment of the indebtedness evidenced by, the promissory note set forth in the Supplement being amended and restated hereby.

SECTION 6. Borrowing Base Certificate, Etc. The Company agrees to furnish a Borrowing Base Certificate to CoBank at such times or intervals as CoBank may from time to time request. Until receipt of such a request, the Company agrees to furnish a Borrowing Base Certificate to CoBank within 30 days after each month end calculating the Borrowing Base as of the last day of the month for which the Certificate is being furnished. However, if no balance is outstanding hereunder on the last day of such period, no Report need be furnished. Regardless of the frequency of the reporting, if at any time the amount outstanding under the Commitment exceeds the Borrowing Base, the Company shall immediately notify CoBank and repay so much of the loans as is necessary to reduce the amount outstanding under the Commitment to the limits of the Borrowing Base.

SECTION 7. Commitment Fee. In consideration of the Commitment, the Company agrees to pay to CoBank a commitment fee on the average daily unused portion of the Commitment at the rate of 12.5

basis points per annum (calculated on a 360 day basis), payable quarterly in arrears by the 20^th day following each calendar quarter. The unused amount of the 364-Day facility will be the difference between the 364-Day Commitment and the sum of the outstanding 364-Day Facility Loans and the undrawn face amount of all outstanding Letters of Credit.

SECTION 8. Letters of Credit. In addition to loans, and if agreeable to CoBank in its sole discretion in each instance, the Company may utilize the Commitment to open irrevocable letters of credit for its account. Each letter of credit shall reduce the amount available under the Commitment by the maximum amount capable of being drawn thereunder. The rights and obligations of the parties with respect to each letter of credit will be governed by the Reimbursement Agreement attached hereto as Exhibit A (which rights and obligations shall be in addition to the rights and obligations of the parties hereunder and under the MLA). This Commitment shall expire on December 31, 2001. The fee for issuing each letter of credit shall be 70 basis points of the face amount of each letter of credit, along with an issuance fee to CoBank, for its own account, equal to the greater of (a) ¹/8% of the face amount of the letter of credit, or (b) $2,000. The Company promises to repay the outstanding balance on the Commitment in full on demand, or if no demand is made, then any time on or before the commitment expiration date of December 31, 2001.

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

In consideration of CoBank issuing one or more letters of credit (each a "Credit") for the Company's account under the Supplement to which this agreement is attached (the "Supplement"), the Company agrees as follows:

1. The Company will pay to CoBank in United States currency and in immediately available funds the amount of each draft drawn or instrument paid under a Credit. In addition, the Company agrees to pay to CoBank such fee for issuing each Credit as CoBank shall prescribe, as well as all customary charges associated with the issuance of a Credit. If a Credit is payable in a foreign currency, the Company will pay to CoBank an amount in United States currency equivalent to CoBank's selling rate of exchange for that currency. In addition to the amounts set forth above, the Company shall pay to CoBank such amounts as CoBank shall determine are necessary to compensate CoBank for any cost attributable to CoBank issuing or having outstanding any Credit resulting from the application of any law or regulation concerning any reserve, assessment, capital adequacy or similar requirement relating to letters of credit, reimbursement agreements with respect thereto, or to similar liabilities or assets of banks, whether existing at the time of the issuance of a Credit or adopted thereafter. Each payment hereunder shall be payable on demand at the place and manner set forth in the Master Loan Agreement between the parties (the "MLA") and with interest from the date of demand to the date paid at CoBank's National Variable Rate. The Company hereby authorizes CoBank to create a loan under the Supplement bearing interest at the variable rate set forth therein for any sums owing hereunder.

2. Neither CoBank nor any of its correspondents shall in any way be responsible for the performance by any beneficiary of its obligations to the Company nor for the form, sufficiency, correctness, genuineness, authority of the person signing, falsification or legal effect of any documents called for under a Credit if such documents on their face appear to be in order. In addition, CoBank and its correspondents may receive and accept or pay as complying with the terms of a Credit any drafts, documents, or certificates, otherwise in order, signed by any person purporting to be an administrator, executor, trustee in bankruptcy, debtor in possession, assignee for the benefit of creditors, liquidator, receiver, or other legal representative of the party authorized under a Credit to draw or issue such instruments or other documents.

3. In the event the Credit is a commercial Credit, then, in addition to the other provisions hereof, the Company: (i) agrees to obtain or cause to be in existence insurance on any merchandise described in the Credit against fire and other usual risks and against any additional risks which CoBank may request; and (ii) authorizes and empowers CoBank to collect the amount due under any such insurance and apply the same against any of the Company's obligations to CoBank arising under the Credit or otherwise. In addition, whether the Credit is a commercial or a standby Credit, the Company represents and warrants that any required import, export or foreign exchange licenses or other governmental approvals relevant to the Credit and the merchandise described therein have been obtained and that the transactions contemplated thereby are not prohibited under any law, rule, regulation, order or the like, including the Foreign Assets Control Regulations of the U.S. Department of Treasury.

4. All directions and correspondence relating to a Credit are to be sent at the Company's risk and CoBank does not assume any responsibility for any inaccuracy, interruption, error, or delay in transmission or delivery by post, telegraph, cable or other electronic means, or for any inaccuracy of translation.

5. CoBank shall not be responsible for any act, error, neglect, default, omission, insolvency or failure in business of any of its correspondents, and any action taken or omitted by CoBank or its correspondents under or in connection with a Credit shall, if taken or omitted with honesty in fact, be binding on the Company and shall not put CoBank or its correspondents under any resulting liability to the Company. In no event shall CoBank be liable for special, consequential or punitive damages.

6. The Company will indemnify CoBank against and hold it harmless from all loss, damage, cost and expense (including attorneys' fees and expenses) arising out of (i) its issuance of or any other action taken by CoBank in connection with a Credit, other than loss or damage resulting from its gross negligence or willful misconduct, and (ii) claims or legal proceedings incident to the collection of amounts owed by the Company hereunder, or the enforcement of CoBank's rights or the rights of others under a Credit, including, without limitation, legal proceedings relating to any court order, injunction or other process or decree restraining or seeking to restrain CoBank from paying any amount under a Credit.

7. In the event: (i) the Company fails to make any payment owing hereunder when the same shall become due and payable; (ii) any covenant or representation or warranty set forth herein is breached; (iii) the "Commitment" (as defined in the Supplement) expires prior to the expiration date of any Credit; or (iv) an "Event of Default" (as defined in the MLA) occurs under the MLA, then, in any such event, the amount of each Credit, together with any amounts payable by us in connection therewith, shall, at CoBank's option, become immediately due and payable. To the extent that any amount paid by the Company pursuant to this Section 7 shall not then be due under the terms of a Credit, such payment shall serve as security for the Company's obligation to indemnify CoBank for any amounts subsequently disbursed by CoBank pursuant to a Credit. Furthermore, upon the institution of any legal proceeding described in Section 6(ii) hereof, the Company will, on demand, assign and deliver to CoBank, as security for the Company's obligation to indemnify CoBank, cash collateral in an amount satisfactory to CoBank.

8. CoBank shall be fully protected in, and shall incur no liability to the Company for acting upon, any oral, telephonic, facsimile, cable or other electronic instructions which CoBank in good faith believes to have been given by any authorized person. CoBank may, at its option, use any means of verifying any instructions received by it and may also, at its option, refuse to act on any oral, telephonic, facsimile, cable or other electronic instructions or any part thereof, without incurring any responsibility for any loss, liability or expenses arising out of such refusal.

9. The Uniform Customs and Practice as most recently published by the International Chamber of Commerce (hereafter called the "UCP") shall in all respects be deemed a part hereof as fully as if incorporated herein, and shall apply to the Credits. To the extent the UCP is inconsistent with the governing law set forth in the MLA, the UCP shall control.

THIS SUPPLEMENT to the Master Loan Agreement dated March 31, 2000 (the "MLA"), is entered into as of March 31, 2000, between CoBANK, ACB ("CoBank") and AMERICAN CRYSTAL SUGAR COMPANY, Moorhead, Minnesota (the "Company").

SECTION 1. The Revolving Term Loan Commitment. On the terms and conditions set forth in the MLA and this Supplement, CoBank agrees to make loans to the Company during the period set forth below in an aggregate principal amount not to exceed $88,698,180.00 at any one time outstanding (the "Commitment"). Within the limits of the Commitment, the Company may borrow, repay and reborrow.

SECTION 2. Purpose and Transfer. The purpose of the Commitment is to finance the operating needs of the Company and to renew, extend, and refinance the Company's obligations to CoBank under the Company's existing reinstatable term loan (the "Existing Reinstatable Term Loan") as currently evidenced by Note No. 31143 (the "Note") entered into pursuant to the Term Loan Agreement dated March 5, 1999 (the "Existing Agreement"). The Company agrees that on the date when all conditions precedent to CoBank's obligation to extend credit hereunder have been satisfied: (a) the principal balance outstanding under the Existing Reinstatable Term Loan shall be transferred to and charged against the Commitment; (b) all accrued obligations of the Company under the Existing Reinstatable Term Loan for the payment of interest or other charges shall be transferred to and become part of the Company's obligations under this Supplement as if fully set forth herein; and, (c) the Note and the Existing Agreement (to the extent applicable to the Note) shall be deemed replaced and superseded, but the indebtedness evidenced by such Note shall not be deemed to have been paid off, by this Supplement and the MLA.

SECTION 3. Term. The term of the Commitment shall be from March 31, 2000, up to but not including March 31, 2001, or such later date as CoBank may, in its sole discretion, authorize in writing.

SECTION 4. Interest. The Company agrees to pay interest on the unpaid balance of the loans in accordance with one or more of the following interest rate options, as selected by the Company:

(A) Variable Rate Option. At a rate per annum equal at all times to the rate of interest established by CoBank from time to time as its National Variable Rate, which Rate is intended by CoBank to be a reference rate and not its lowest rate. The National Variable Rate will change on the date established by CoBank as the effective date of any change therein and CoBank agrees to notify the Company promptly after any such change.

(B) Quoted Rate Option. At a fixed rate per annum to be quoted by CoBank in its sole discretion in each instance. Under this option, rates may be fixed on such balances and for such periods as may be agreeable to CoBank in its sole discretion in each instance.

(C) LIBOR Option. At a fixed rate equal to "LIBOR" (as hereinafter defined) plus the Applicable LIBOR Margin per annum (as described in terms of basis points ("bps") in the chart immediately set forth below). Under this option: (a) rates may be fixed for "Interest Periods" (as hereinafter defined) of 1, 2, 3, and 6 months, as selected by the Company; (b) the minimum amount that may be fixed at any one time shall be $2,000,000.00; and (c) rates may only be fixed on a "Banking Day" (as hereinafter defined) or, at the option of the Company, on 2 Banking Days' prior notice. For purposes hereof: (i) "LIBOR" shall mean the rate indicated by Telerate (rounded upward to the nearest thousandth) as having been quoted by the British Bankers Association at 11:00 a.m. London time on the date the Company elects to fix a rate under this option for the offering of U.S. dollar deposits in the London interbank market for the Interest Period designated by the Company; (ii) "Banking Day" shall mean a day on which CoBank is open for business, dealings in U.S. dollar deposits are being carried out in the London interbank market, and banks are open for business in New York City and London, England; and (iii) "Interest Period" shall mean a period commencing on the day the Company elects to fix a rate under this option (or, at the option of the

Company, two Banking Days later) and ending on the numerically corresponding day in the next calendar month or the month that is 2, 3 or 6 months thereafter, as the case may be; provided, however, that: (x) in the event such ending day is not a Banking Day, such period shall be extended to the next Banking Day unless such next Banking Day falls in the next calendar month, in which case it shall end on the preceding Banking Day; and (y) if there is no numerically corresponding day in the month, then such period shall end on the last Banking Day in the relevant month.

Rate Product	Index	Spread Over Index in Basis Points
One Month	LIBOR	90 bps
Two Months	LIBOR	90 bps
Three Months	LIBOR	90 bps
Six Months	LIBOR	90 bps

(D) Treasury Option. At a fixed rate equal to Applicable "Treasury" Margin per annum (as described in terms of basis points ("bps") in the chart immediately set forth below) above the "U.S. Treasury Rate" (as hereinafter defined). Under this option, balances of $2,000,000.00 or more may be fixed on or before for periods ranging from one year to the final maturity date of the loan, as selected by the Company. However, rates may not be fixed in such a manner as to require the Company to have to repay any fixed rate balance prior to the last day of its fixed rate period in order to pay any installment of principal. For purposes hereof, the "U.S. Treasury Rate" shall mean the yield to maturity on U.S. Treasury instruments having the same maturity date as the last day of the fixed rate period selected by the Company, as calculated from the bid price indicated by Telerate (page 5) at the time the rate is fixed. If, however, no instrument is indicated for the maturity selected, then the rate shall be interpolated based on the bid prices quoted for the next longest and shortest maturities so indicated. In the event Telerate ceases to provide such quotations or materially changes the form or substance of page 5 (as determined by CoBank), then CoBank will notify the Company and the parties hereto will agree upon a substitute basis for obtaining such quotations

One Year	U.S.$ Constant Maturity Treasury ("US$CMT")	125 bps
Two Years	US$CMT	125 bps
Three Years	US$CMT	125 bps
Four Years	US$CMT	125 bps
Five Years	US$CMT	125 bps
Seven Years	US$CMT	140 bps
Ten Years	US$CMT	140 bps
Floor (Minimum) Margin (For One to Ten Year Fixed Rate Products Only)	CoBank's cost of funds (as reasonably determined by CoBank in its sole discretion)	105 bps

The spread over all of the above indices, including the Floor Margin, may increase or decrease for future fixed amounts based on the Borrower's previous fiscal quarter's leverage ratio, as follows:

Leverage Ratio (as defined below)		Increase / Decrease to Spread	Change to Libor and Treasury Margins (In Basis Points)
A.	Equal to or greater than 1.35:1.00	Increase	20
B.	Equal to or greater than 1.20:1.00, but less than 1.35:1.00	None	0
C.	Less than 1.20:1.00, but greater than or equal to 1.00:1.00	Decrease	10
D.	Less than 1.00:1.00	Decrease	20

Leverage Ratio: The Borrower will maintain a leverage ratio of not more than 1.50:1.0, and attain a leverage ratio of not more than 1.40:1.0 on November 30, 2002. Leverage ratio is long term debt (excluding current maturities) calculated in accordance with GAAP plus or minus the difference between actual working capital and minimum net working capital (as defined in the MLA No. Z269, Section 10), divided by total members investments plus the estimated unit retains.

The spread shall be adjusted quarterly on the latter of either: (a) five business days after the Bank's receipt of the Borrower's certification of compliance with the leverage ratio, or (b) 30 days after the end of each calendar quarter.

The Company shall select the applicable rate option at the time it requests a loan hereunder and may, subject to the limitations set forth above, elect to convert balances bearing interest at the variable rate option to one of the fixed rate options. Upon the expiration of any fixed rate period, interest shall automatically accrue at the variable rate option unless the amount fixed is repaid or fixed for an additional period in accordance with the terms hereof. Notwithstanding the foregoing, unless CoBank otherwise consents in its sole discretion in each instance, rates may not be fixed for periods expiring after the maturity date of the loans. In the event CoBank so consents and the Commitment is not renewed, then each balance so fixed shall be due and payable on the last day of its fixed rate period, and the promissory note set forth below shall be deemed amended accordingly. All elections provided for herein shall be made telephonically or in writing and must be received by 12:00 noon Company's local time. Interest shall be calculated on the actual number of days each loan is outstanding on the basis of a year consisting of 360 days and shall be payable quarterly in arrears by the 20th day of the following month.

SECTION 5. Promissory Note. The Company promises to repay the loans that are outstanding in annual principal payments of $9,396,579.17 each due on or before December 31^st of each year through December 31, 2008, and a final principal payment due on or before December 31, 2009. All outstanding balances shall be repaid by December 31, 2009. If any installment due date is not a day on which CoBank is open for business, then such payment shall be made on the next day on which CoBank is open for business. In addition to the above, the Company promises to pay interest on the unpaid principal balance hereof at the times and in accordance with the provisions set forth in Section 4 hereof.

The Company shall be permitted to make special payments, in a minimum amount of $388,500.00, on the variable rate portion of this loan, when all short term financing, including the Company's seasonal loans, Commodity Credit Corporation loans and other short term loans have been zeroed out. These special payments may be readvanced through the expiration date of the Commitment. Reinstatement may be denied and canceled at any time at the option of CoBank. The reinstatable commitments arising from such special payments shall be subject to the Commitment Fee as described in Section 8 below.

Commitment, prepayments shall, unless CoBank otherwise agrees, be applied to principal installments in the inverse order of their maturity and to such balances, fixed or variable, as CoBank shall specify.

SECTION 7. Commitment Fee. In consideration of the Commitment, the Company agrees to pay to CoBank a commitment fee on the average daily unused portion of the Commitment at the rate of 12.5 basis points per annum (calculated on a 360 day basis), payable quarterly in arrears by the 20th day following each calendar quarter. Such fee shall be payable for each calendar quarter (or portion thereof) occurring during the original or any extended term of the Commitment.

SECTION 8. Commitments Arising From Special Payments. Commitments arising as a result of special payments described in Section 5 above shall be subject to a commitment fee of 25 basis points (0.25%) on an annualized basis, on the average daily commitment. Any such fees incurred shall be payable on the last day of the calendar quarter, in arrears, computed on the basis of a year of 360 days for the actual number of days elapsed in which such reinstatable commitments were outstanding.

SECTION 9. Security. In addition to any other security that may otherwise be required or provided, the Company's obligations under this Supplement are secured by that Restated Mortgage and Security Agreement dated September 15, 1998, from American Crystal Sugar Company to St. Paul Bank for Cooperatives (now known as CoBank as a result of merger), as Collateral Agent.

If, however, no instrument is indicated for the maturity selected, then the rate shall be interpolated based on the bid prices quoted for the next longest and shortest maturities so indicated. In the event Telerate ceases to provide such quotations or materially changes the form or substance of page 5 (as determined by CoBank), then CoBank will notify the Company and the parties hereto will agree upon a substitute basis for obtaining such quotations
