On or before February 14, 2012, CARDINAL ETHANOL, LLC ("BORROWER"), promises to
pay to the order of FIRST NATIONAL BANK OF OMAHA ("BANK") at any of its offices
in Omaha, Nebraska the principal sum hereof, which shall be Fifteen Million and
no/100 Dollars ($15,000,000.00) or so much thereof as may have been advanced by
BANK and shown on the records of BANK to be outstanding under this SIXTH AMENDED
AND RESTATED REVOLVING PROMISSORY NOTE ("REVOLVING NOTE") and the AGREEMENT (as
defined below). Interest on the principal balance from time to time outstanding
shall accrue and be payable as provided for in the AGREEMENT. The principal
balance of this REVOLVING NOTE shall be payable as provided for in the
AGREEMENT.

This REVOLVING NOTE is executed pursuant to that certain Construction Loan
Agreement dated December 19, 2006 between BANK and BORROWER (the Construction
Loan Agreement, together with all amendments, modifications and supplements
thereto and all restatements and replacements thereof is called the
"AGREEMENT"), as amended including by that certain Ninth Amendment of
Construction Loan Agreement of even date herewith. This REVOLVING NOTE amends
and restates that certain FIFTH AMENDED AND RESTATED REVOLVING PROMISSORY NOTE
dated February 15, 2011 executed and delivered by BORROWER in favor of BANK, but
is not a novation of such note. The AGREEMENT, and any amendments or
substitutions thereof or thereto, contains additional terms and conditions,
including default and acceleration provisions, which are incorporated into this
REVOLVING NOTE by reference. All capitalized terms not otherwise defined herein
shall have the same meanings as set forth in the AGREEMENT.

The aggregate unpaid principal amount hereof plus interest shall become
immediately due and payable without demand or further action on the part of BANK
upon the occurrence of an EVENT OF DEFAULT as set forth under the AGREEMENT or
any other LOAN DOCUMENT. If the maturity date of this REVOLVING NOTE is
accelerated as a consequence of an EVENT OF DEFAULT, then BANK shall have all
the rights and remedies provided for in the AGREEMENT, the other LOAN DOCUMENTS
or otherwise available at law or in equity. The rights, powers, privileges,
options and remedies of BANK provided in the AGREEMENT, the other LOAN DOCUMENTS
or otherwise available at law or in equity shall be cumulative and concurrent,
and may be pursued singly, successively or together at the sole discretion of
BANK, and may be exercised as often as occasion therefor shall occur. No delay
or discontinuance in the exercise of any right, power, privilege, option or
remedy shall be deemed a waiver of such right, power, privilege, option or
remedy, nor shall the exercise of any right, power, privilege, option or remedy
be deemed an election of remedies or a waiver of any other right, power,
privilege, option or remedy. Without limiting the generality of the foregoing,
BANK' s waiver of an EVENT OF DEFAULT shall not constitute a waiver of
acceleration in connection with any future EVENT OF DEFAULT. BANK may rescind
any acceleration of this REVOLVING NOTE without in any way waiving or affecting
any acceleration of this REVOLVING NOTE in the future as a consequence of an
EVENT OF DEFAULT. BANK' s acceptance of partial payment or partial performance
shall not in any way affect or rescind any acceleration of this REVOLVING NOTE
made by BANK.

Unless prohibited by law, BORROWER will pay on demand all reasonable costs of
collection, reasonable legal expenses and reasonable attorneys' fees and costs
incurred or paid by BANK in collecting and/or enforcing this REVOLVING NOTE.
Furthermore, BANK reserves the right to offset without notice

--------------------------------------------------------------------------------

all funds held by BANK against debts owing to BANK by BORROWER.

All makers and endorsers hereby waive presentment, demand, protest and notice of
dishonor, consent to any number of extensions and renewals for any period
without notice; and consent to any substitution, exchange or release of
collateral, and to the addition or releases of any other party primarily or
secondarily liable.
