Item 1.01 Entry into a Material Definitive Agreement.

Credit Agreement

In connection with the Merger (as defined below), on March 9, 2012, BI-LO Holding, LLC and BI-LO, LLC (“BI-LO”) entered into a $700 million senior secured revolving credit facility, together with Deutsche Bank Trust Company Americas, as Administrative Agent and Collateral Agent, and the other lenders and agents party thereto (the “New Credit Agreement”), of which up to $250 million may be used for the issuance of letters of credit. Concurrent therewith, Winn-Dixie Stores, Inc. (the “Company”) and its subsidiaries (other than WIN General Insurance, Inc. (“WIN General”)) entered into a guarantee of such credit agreement and granted a security interest on a first priority basis on present and future cash, deposit accounts, accounts receivable, inventory and certain related assets (the “ABL Priority Collateral”) and on a second priority basis in existing and after acquired intellectual property, equipment, a pledge of equity interests and substantially all of the Company’s and its subsidiaries’ (other than WIN General) other assets that do not constitute ABL Collateral (the “Notes Priority Collateral”).

Under the New Credit Agreement, BI-LO is able to borrow and have letters of credit issued from time to time in an aggregate amount equal to the lesser of $700 million and the aggregate value (as determined pursuant to valuation methods and advance rates set forth in the New Credit Agreement) of certain borrowing base assets comprised of eligible accounts receivable, eligible pharmacy scripts, eligible inventory and eligible credit card receivables, in each case reduced by certain reserves (referred to in the New Credit Agreement as the “Borrowing Base”). The New Credit Agreement has a five year term and matures in March of 2017, at which time all principal amounts outstanding under the New Credit Agreement will be due and payable. Borrowings under the New Credit Agreement bear interest at a rate equal to either the base rate or LIBOR from time to time in effect, at BI-LO’s option, plus an applicable margin above the specified index. The applicable margin is determined by reference to BI-LO’s historical “Excess Availability” for borrowings. Depending on the amount of Excess Availability, applicable margins for LIBOR-based loans and fees for letters of credit range from 1.75% to 2.25%, and applicable margins for base rate-based loans range from 0.75% to 1.25%. The Credit Agreement may, subject to certain conditions and to receipt of commitments from new or existing lenders, be increased up to a total of $900 million at the request of BI-LO.

The proceeds of the New Credit Agreement may be used to effect the Merger, to repay the indebtedness under the Pre-Merger Credit Agreement (defined below), to refinance letters of credit issued on behalf of the Company or one of its subsidiaries under the Pre-Merger Credit Agreement or issued on behalf of BI-LO or one of its subsidiaries under its existing credit facility (both of which were terminated on March 9, 2012), to pay fees and expenses in connection with the Merger and its related transactions, and for working capital and general corporate purposes.

The New Credit Agreement places limitations on the ability of the Company and its subsidiaries to, among other things, incur debt, create other liens on its assets, make investments, sell assets, pay dividends, undertake transactions with affiliates, enter into merger transactions, and enter into unrelated businesses. The New Credit Agreement also contains various customary representations and warranties, financial and collateral reporting requirements and other affirmative and negative covenants.

Amounts owed under the New Credit Agreement may be accelerated and the Lenders may exercise other remedies available to them upon the occurrence of various events of default set forth in the New Credit Agreement, including the failure to make principal or interest payments when due, breaches of covenants, representations and warranties set forth in the New Credit Agreement, and defaults under other debt obligations.

Senior Secured Notes

On January 27, 2011, BI-LO and its wholly-owned subsidiary, BI-LO Finance Corp. (“BI-LO Finance”, and together with BI-LO, the “Issuers”) entered into a Purchase Agreement (the “Purchase Agreement”) with Citigroup Global Markets Inc. and Deutsche Bank Securities Inc. (as representatives of initial purchasers) under which the Issuers proposed to issue and sell to the initial purchasers named therein $285,000,000 of Issuers’ 9.25% Senior Secured Notes due 2019 (the “Notes”). The closing of the sale of

the notes occurred on February 3, 2011. The Notes are governed by an Indenture, dated February 3, 2011 (the “Indenture”), by and among the Issuers and Wells Fargo Bank, National Association, as trustee. The Notes are secured on a first priority basis on the Notes Priority Collateral of BI-LO and its subsidiaries and on a second priority basis on the ABL Priority Collateral of BI-LO and its subsidiaries. Concurrent with the Merger and entry by the Company and its subsidiaries (other than WIN General) into secured guarantee obligations in respect of the New Credit Agreement, the Company and its subsidiaries (other than WIN General) entered into a supplemental indenture as subsidiary guarantors and joinder to security documents in respect of the Indenture pursuant to which the Company and its subsidiaries (other than WIN General) granted a security interest on a first priority basis in its Notes Priority Collateral and on a second priority basis in its ABL Priority Collateral.

Item 1.02. Termination of a Material Definitive Agreement.

In connection with the Merger (as defined below), on March 9, 2012, the Company terminated its Second Amended and Restated Credit Agreement, dated as of March 18, 2011, as amended, among the Company, Wells Fargo Bank, National Association, as administrative agent and the other parties thereto (the “Pre-Merger Credit Agreement”) and repaid in full all outstanding loans and advances under the Pre-Merger Credit Agreement in connection with such termination. No penalties were paid in connection with such repayments.

The description of the Pre-Merger Credit Agreement set forth in the Company’s Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 21, 2011 is incorporated herein by reference.
