"Eurocurrency Liabilities" [as hereinafter defined] for banks subject to "FRB Regulation D" [as

U.S. dollars deposits, as published by Bloomberg or another major information vendor listed on BBA's official website on the
first "U.S. Banking Day" (as hereinafter defined) in each week, with such rate to change weekly on such day. The
rate shall be reset automatically, without the necessity of notice being provided to the Company or any other party, on the
first "U.S. Banking Day" of each succeeding week, and each change in the rate shall be applicable to all balances
subject to this option. Information about the then current rate shall be made available upon telephonic request. For purposes
hereof: (1) "U.S. Banking Day" shall mean a day on which CoBank is open for business and banks are open for
business in New York, New York; (2) "Eurocurrency Liabilities" shall have the meaning as set forth in "FRB
Regulation D"; and (3) "FRB Regulation D" shall mean Regulation D as promulgated by the Board of Governors of

(B)   Quoted Rate.
At a fixed rate per annum to be quoted by CoBank in its sale discretion

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, rates may not be fixed for periods expiring after the maturity date of the
loans and rates may not be fixed in such a manner as to cause the Company to have to break any fixed rate balance in order to pay
any installment of principal. 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

30 days after each month end calculating the Borrowing Base as of the last day of the month for which the report is being furnished.

to the limits of the Borrowing Base.

amount capable of being drawn under the letters of credit exceeds the Borrowing Base, then the Company shall immediately notify
C08ank and pay to CoBank (to be held as cash collateral) an amount equal to such excess.
