On March 30, 2020, Cardinal Ethanol, LLC and its primary lender, First National Bank of Omaha, executed a Fifteenth Amendment of First Amended and Restated Construction Loan Agreement to be effective as of February 28, 2020, which amends the First Amended and Restated Construction Loan Agreement dated June 10, 2013. The Amendment extends the termination date of the Revolving Credit Loan from February 28, 2020 to February 28, 2021. In addition, the Amendment modifies the definition of "LIBOR Rate" in order to provide for a process for the parties to agree upon a new interest rate index and margin to be applied to that index in the event that FNBO determines that the LIBOR Rate is unavailable or unreliable. The Amendment provides that FNBO, acting in a commercially reasonable manner, will propose to Cardinal (i) a replacement interest rate index that gives due consideration to the then prevailing market convention for determining a rate of interest for comparable bank-originated commercial loans in the United States at such time; and (ii) any change necessary to the applicable margin in order to approximate the then current interest rate on the loans. The Agreement may then be amended to reflect these changes with Cardinal's prior written consent, which consent shall not be unreasonably withheld, delayed, or conditioned. Finally, the Amendment provides for a minimum fixed charge coverage ratio of no less than 1.15:1.0 measured quarterly on a rolling four quarter average basis if Cardinal's working capital is less that $23,000,000 for any reporting period. The Amendment also provides for a debt service charge coverage ratio of no less than 1.25:1.0 measured quarterly on a rolling four quarter average basis, in lieu of the fixed charge coverage ratio, if Cardinal's working capital is equal to or more that $23,000,000. The Amendment reduces the applicable threshold from $25,000,000 to $23,000,000.
