Under the Term Loan Forbearance, Term Loan Agent and Required Lenders agreed, subject to specified limitations and conditions, not to take any action to enforce any rights or remedies under the Term Loan Agreement which may result from the potential events of default caused by (i) Aventine’s failure to make the interest payment due under the Term Loan Agreement on July 31, 2012, (ii) Aventine’s potential failure to satisfy the minimum liquidity and debt-to capitalization financial covenants in the Term Loan Agreement and (iii) any cross-default triggered by events of default (as described below) under the Revolving Credit Agreement (as defined below). The Term Loan Forbearance will terminate on the earlier of (i) September 7, 2012 or (ii) the occurrence of a further event of default under the Term Loan Agreement or the occurrence of certain other events specified in the Term Loan Forbearance. The Term Loan Forbearance requires that Aventine give certain information to Required Lenders.

In consideration for the Term Loan Forbearance, Aventine has agreed to pay to Required Lenders (i) a forbearance fee of 1% of the outstanding principal balance of loans under the Term Loan Agreement, which fee will be paid in kind and (ii) the default interest rate on the outstanding principal balance of the loans under the Term Loan Agreement from the date of the Term Loan Forbearance until Aventine is no longer in default under the Term Loan Agreement, which interest will be paid in kind.

Under the Revolver Forbearance, Sole Lender agreed, subject to specified limitations and conditions, not to take any action to enforce any rights or remedies under the Revolving Credit Agreement which may result from the potential events of default caused by (i) Aventine’s potential failure to satisfy the minimum liquidity and minimum ethanol production at the Pekin, Illinois plant financial covenants in the Revolving Credit Agreement and (ii) any cross-default triggered by events of default (as described above) under the Term Loan Agreement. The Revolver Forbearance will terminate on the earlier of (i) September 7, 2012 or (ii) the occurrence of a further event of default under the Revolving Credit Agreement or the occurrence of certain other events specified in the Revolver Forbearance. The Revolver Forbearance also requires that Aventine give Sole Lender certain information. Additionally, the Revolver Forbearance amends the Revolving Credit Agreement to change the date for cash collateralization of the undrawn amount of Aventine’s outstanding letters of credit from July 27, 2012 (as previously reported by Aventine on July 12, 2012) to September 7, 2012.
