Item 1.02 Termination of a Material Definitive Agreement

On April 18, 2012, the Lancaster Colony Corporation (the “Company”) terminated its $160 million existing bank credit agreement (the “Old Credit Agreement”) dated October 5, 2007. The Old Credit Agreement was replaced by a new credit agreement, as described in Item 2.03 below.

Item 2.03 Creation of a Direct Financial Obligation or Obligation under an Off-Balance Sheet Arrangement of a Registrant

On April 18, 2012, the Company entered into a new $120 million credit agreement (the “New Credit Agreement”) with the Lenders named in the New Credit Agreement and JPMorgan Chase Bank, N.A. as Administrative Agent.

The material terms of the New Credit Agreement are substantially similar to the terms of the Old Credit Agreement, except with respect to maturity, interest rate margins and fees.

The New Credit Agreement provides that the Company may borrow, for the five-year term of the agreement, on a revolving credit basis, up to a maximum of $120 million at any one time, with potential to expand the total credit availability to $200 million based on consent of the issuing banks and certain other conditions. All outstanding amounts under the New Credit Agreement are due and payable on April 18, 2017. Interest is variable based upon formulas tied to LIBOR or an alternative base rate defined in the New Credit Agreement, at the Company’s option. The Company must also pay facility fees that are tied to its then-applicable consolidated leverage ratio. Loans may be used for general corporate purposes. The Company’s obligations under the New Credit Agreement are not secured.

The New Credit Agreement contains certain restrictive covenants, including limitations on indebtedness, asset sales and acquisitions. There are two principal financial covenants: an interest expense test that requires the Company to maintain an interest coverage ratio not less than 2.5 to 1 at the end of each fiscal quarter; and an indebtedness test that requires the Company to maintain a consolidated leverage ratio not greater than 3 to 1 at all times. The interest coverage ratio is calculated by dividing Consolidated EBIT (as defined more specifically in the New Credit Agreement) by Consolidated Interest Expense (as defined more specifically in the New Credit Agreement), and the leverage ratio is calculated by dividing Consolidated Debt (as defined more specifically in the New Credit Agreement) by Consolidated EBITDA (as defined more specifically in the New Credit Agreement).

At April 20, 2012, there were no borrowings outstanding under the New Credit Agreement.

The foregoing description of the New Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the New Credit Agreement, which is filed as Exhibit 10.1 and attached hereto.
