    REVOLVING
TERM LOAN SUPPLEMENT

    


    


    THIS SUPPLEMENT to the Master Loan
Agreement dated October 6, 2005 (the “MLA”), is entered into as of September 16,
2009 between CoBANK, ACB (“CoBank”) and
SOUTH DAKOTA SOYBEAN
PROCESSORS, LLC, Volga, South Dakota (the “Company”), and amends and
restates the Supplement dated March 23, 2009 and numbered RIB05
IT05D.

    


    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 from the date hereof; up
to and including September 20, 2013, in an aggregate principal amount not to
exceed, at any one time outstanding, $11,900,000.00 less the amounts scheduled
to be repaid during the period set forth below in Section 5 (the “Commitment”).
Within the limits of the Commitment, the Company may borrow, repay, and
reborrow.

    


    The
Company may, in its sole discretion, elect to permanently reduce the amount of
the Commitment by giving CoBank ten (10) days prior written notice. Said
election shall be made only if the Company is not in default at the time of the
election and will remain in compliance with all financial covenants after such
reduction. Any such reduction shall be treated as an early, voluntary reduction
of the Commitment amount and shall not delay or reduce the amount of any
scheduled Commitment reduction under Section 5 hereof (which reductions shall
continue in semi-annual increments of $1,300,000.00 on the dates determined in
accordance with Section 5), but rather shall result
in an earlier expiration of the Commitment and final maturity of the
loans.

    


    SECTION 2. Purpose. The
purpose of the Commitment is to provide working capital to the Company and to
finance the construction of a soybean refinery.

    


    SECTION 3. Term.
Intentionally Omitted.

    


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

    Company:

    


    (A)                 One-Month LIBOR Index Rate. At
a rate (rounded upward to the nearest 1/100th and adjusted for reserves required
on “Eurocurrency Liabilities” [as hereinafter defined] for banks subject to “FRB
Regulation D” [as hereinafter defined] or required by any other federal law or
regulation) per annum equal at all times to 3.25% above the rate quoted by the
British Bankers Association (the “BBA”) at 11:00 a.m. London time for the
offering of one (1)-month U.S. dollars deposits, as published by Bloomberg or
another major information vender 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) “Eurocurreney Liabilities” shall have the meaning as set
forth in “FRB Regulation B”; and (3) Regulation D” shall mean Regulation D as
promulgated by The Board of Governors of the Federal Reserve System, 12 CFR Part
204, as amended.

    


    (B)                  Quoted Rate. 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, provided that: (1)
the minimum fixed period shall be 30 days; (2) amounts may be fixed in
increments of $100,000.00 or multiples thereof; and (3) the maximum number of
fixes in place at any one time shall be five.

    


    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 provided for above 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 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 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.

    


    SECTION 5. Promissory Note.
The Company promises to repay on the date of each reduction in the
Commitment, the outstanding principal, if any, that is in excess of the
available balance. The available balance shall be decreased by $1,300,000.00 on
the 20th day of each September and March beginning September 20, 2009, and
continuing through and including March 20, 2013, followed by a final reduction
at the expiration of the Commitment on September, 20, 2023, at which time any
outstanding balance shall be due and payable in full. 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. 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.

trust.

commitment fee on the average daily unused portion of the Commitment at the rate
of 0.50% 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
