| | (a). FIXED
 RATE II NOTES. Interest on the principal balance outstanding on the FIXED
 RATE II NOTES shall accrue and be calculated using a rate of Three Percent
 (3%) over the Index resulting in an initial rate of 3.294% per annum based on
 a year of 360 days. Interest on the FIXED RATE II NOTES is computed on an
 actual/360 basis; that is, by applying the ratio of the interest rate over a
 year of 360 days, multiplied by the outstanding principal balance, multiplied
 by the actual number of days the principal balance is outstanding. All
 interest payable under the FIXED RATE II NOTES is computed using this method.
 NOTICE: Under no circumstances will the interest rate on the FIXED RATE II
 NOTES be more than the maximum rate allowed by applicable law. The principal
 balance of the FIXED RATE II NOTES will bear interest after maturity and
 after the occurrence and during the continuance of an EVENT OF DEFAULT at a
 variable per annum rate equal to the Index plus nine percent (9%), but not to
 exceed the maximum rate allowed by law. BORROWER will pay interest quarterly,
 in arrears, on the same dates that principal installments are due. Accrued
 and unpaid interest must also be paid on the LOAN TERMINATION DATE applicable
 to the FIXED RATE II LOAN, whether by acceleration or otherwise. The interest
 rate change will not occur more often than each quarter on the INTEREST RATE
 CHANGE DATE applicable to the FIXED RATE II TERM LOAN.

To the extent
necessary, the FIXED RATE II NOTES are hereby amended consistent with the
foregoing.

| | Index, adjusted if necessary for any minimum and
     maximum rate limitations described below, resulting in an initial rate of
     5.10% per annum based on a year of 360 days. Interest on the REVOLVING NOTES
     is computed on an actual/360 basis; that is, by applying the ratio of the
     interest rate over a year of 360 days, multiplied by the outstanding principal
     balance, multiplied by the actual number of days the principal balance is
     outstanding. All interest payable under the REVOLVING NOTES is computed
     using this method. NOTICE: With respect to the REVOLVING NOTES, under no
     circumstances will the Index be less than two percent (2%) per annum. The
     principal balance of the REVOLVING NOTES will bear interest after maturity
     and after the occurrence and during the continuance of an EVENT OF DEFAULT
     at a variable per annum rate equal to the Index plus six percent (6%), but
     not to exceed the maximum rate allowed by law. Borrower will pay interest
     quarterly, in arrears, on the first calendar day of each quarter. Accrued
     and unpaid interest must also be paid on the LOAN TERMINATION DATE applicable
     to the REVOLVING LOAN, whether by acceleration or otherwise. The interest
     rate change will not occur more often than each quarter on the INTEREST
     RATE CHANGE DATE applicable to the REVOLVING LOAN.

BORROWERS capital expenditures in BORROWERS 2010 fiscal year and inserting in
lieu thereof $5,000,000.00. Such increase will be used by BORROWER for the sole
purpose of construction and equipping of 2 additional grain bins at the
PROJECT. Commencing with BORROWERS 2011 fiscal year, and for each fiscal year
thereafter, BORROWERS capital expenditures in any such fiscal year may not
exceed $1,000,000.00 without the prior written consent of ADMINISTRATIVE AGENT
as provided for in Section 6.4.11. BANKS acknowledge that on May 10, 2010
