Item 1.01. Entry into a Material Definitive Agreement.

On December 3, 2014, Green Plains Cattle Company, LLC (the “Borrower”), a wholly-owned subsidiary of Green Plains Inc. (“Green Plains”), entered into a revolving credit facility agreement (the “Revolving Credit Facility”) due October 2017. The Revolving Credit Facility includes total revolving credit commitments of $100 million and an accordion feature whereby amounts available under the facility may be increased by up to $50 million of new lender commitments upon agent approval. Bank of the West and ING Capital LLC served as joint administrative agents and arrangers on the Revolving Credit Facility.

The proceeds from the Revolving Credit Facility will primarily be used to finance working capital for the cattle feedlot operations. The Revolving Credit Facility requires monthly interest payments on loan advances payable in arrears on the last business day of each month, with the principal balance and remaining interest due upon maturity. The Revolving Credit Facility will bear interest at a variable rate per annum, equal to LIBOR plus 3.0%, 2.5% or 2.0%, depending upon availability.

The Revolving Credit Facility is secured by substantially all of the assets of the Borrower. The terms of the Revolving Credit Facility require the Borrower to maintain a minimum working capital of $15.0 million, a minimum tangible net worth of $20.0 million, a maximum total debt to tangible net worth of 3.50 to 1.00, and limitations on distributions, dividends or loans to Green Plains.

The Revolving Credit Facility provides for customary events of default which include (subject in certain cases to customary grace and cure periods), among others, the following: nonpayment of principal or interest; breach of covenants or other agreements in the Revolving Credit Facility; material incorrect representations and warranties; defaults in failure to pay certain other indebtedness; and certain events of insolvency. If any event of default occurs, the remaining principal balance and accrued interest on the Revolving Credit Facility will become immediately due and payable.
