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, rates may not be fixed for periods expiring after the maturity date of the loans. All elections provided for herein shall be made electronically (if applicable), telephonically or in writing and must be received by CoBank not later than 12:00 Noon Company’s local time in order to be considered to have been received on that day; provided, however, that in the case of LIBOR rate loans, all such elections must be confirmed in writing upon CoBank’s request. 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 monthly in arrears by the 20th day of the following month or on such other day in such month as CoBank shall require in a written notice to the Company; provided, however, in the event the Company elects to fix all or a portion of the indebtedness outstanding under the LIBOR interest rate option above, at CoBank’s option upon written notice to the Company, interest shall be payable at the maturity of the Interest Period and if the LIBOR interest rate fix is for a period longer than three months, interest on that portion of the indebtedness outstanding shall be payable quarterly in arrears on each three-month anniversary of the commencement date of such Interest Period, and at maturity.

SECTION 5. Promissory Note. The Company promises to repay the unpaid principal balance of the loans on 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. Letters of Credit. If agreeable to CoBank in its sole discretion in each instance, in addition to loans, the Company may utilize the Commitment to open irrevocable letters of credit for its account. Each letter of credit will be issued within a reasonable period of time after CoBank’s receipt of a duly completed and executed copy of CoBank’s then current form of Application and Reimbursement Agreement or, if applicable, in accordance with the terms of any CoTrade Agreement between the parties, and shall reduce the amount available under the Commitment by the maximum amount capable of being drawn thereunder. Any draw under any letter of credit issued hereunder shall be deemed a loan under the Commitment and shall be repaid in accordance with this Supplement. Each letter of credit must be in form and content acceptable to CoBank and must expire no later than the maturity date of the Commitment.

SECTION 7. Security. The Company’s obligations hereunder and, to the extent related hereto, the MLA, shall be secured as provided in the Security Section of the MLA, including without limitation as a future advance under any existing mortgage or deed of trust.

SECTION 8. Amendment Fee. In consideration of the amendment, the Company agrees to pay to CoBank on the execution hereof a fee in the amount of $50,000.00.

SECTION 9. 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 0.375% per annum (calculated on a 360-day basis), payable monthly in arrears by the 20th day following each month. Such fee shall be payable for each month (or portion thereof) occurring during the original or any extended term of the Commitment.
