EXTENDED PAYMENT TERMS AGREEMENT

This Extended Payment Terms Agreement (the “Agreement”) is dated June 29, 2009, and is between WEST CENTRAL COOPERATIVE, an Iowa cooperative association (“West Central”), and REG RALSTON, LLC, an Iowa limited liability company (“REG Ralston”).

West Central has been supplying soybean oil produced by it to REG Ralston for use in REG Ralston’s biodiesel production facility (the “Facility”) located next to West Central’s grain cooperative and soybean crushing facilities at Ralston, Iowa.

The parties may agree in the future to have West Central purchase supplies of animal fat, corn oil and other products as feedstock for resale to REG Ralston for use in the Facility (soybean oil, corn oil, animal fat and such other feedstocks are collectively referred to in this Agreement as “Feedstock”).

The parties desire to set forth their understanding as to the terms of payment that will apply for soybean oil that West Central sells to REG Ralston as well as for any other Feedstock that West Central may agree in the future to purchase and resell to REG Ralston.

Therefore, the parties agree as follows:

1. Time of Payment. All payments for Feedstock delivered by or for West Central to REG Ralston shall be paid by wire transfer to an account designated by West Central on or before the 45th day after West Central delivers an invoice for such Feedstock to REG Ralston.

Said interest shall be computed on an actual day, three hundred sixty day year basis and be payable monthly in arrears by the 15th day after the end of each month. So long as any Event of Default (as defined below) shall occur or be continuing, the interest rate shall increase to the lesser of (a) a rate per annum equal to the greater of (determined monthly): (i) *** percent (***%) per annum over and above the LIBOR Rate (which rate of interest shall fluctuate monthly as provided below) or (ii) *** percent (***%) per annum, and (b) the highest rate permitted by law. “LIBOR Rate” means the daily average of interbank offered rates for US Dollar deposits in the London market based on quotations at major banks, as published under the heading “London InterBank Offered Rates (LIBOR)” in the “Monthly Rates” column of The Wall Street Journal for the one month maturity as of the date which is two business days before the first day of the month for which interest is to be computed. The LIBOR Rate and the interest rate under this Agreement will be determined and reset for each calendar month as provided above.

4. Application and Term of Agreement. The extended payment terms of this Agreement, including without limitation the due dates for payments, the accrual of and calculation of interest and maximum credit, shall apply to all Feedstock delivered by or for West Central to REG Ralston on or after February 12, 2009.
