Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the Registrant under any of the following provisions:

As previously announced, on June 8, 2012, Spartan Stores, Inc. (the “Company”) entered into an amendment (the “Amendment”) to its existing Loan and Security Agreement dated December 23, 2003, by and among the Company and the Company’s subsidiaries, as borrowers, Wells Fargo Capital Finance, LLC, as administrative agent and lender, and the other lenders that are parties thereto (as amended, the “Amended Loan Agreement”). The Amendment, in part, incorporates all the terms and provisions of the Amended Loan Agreement as an exhibit.

Under the terms of the Amended Loan Agreement, the maturity of the borrowings available under the credit facility was extended to June 8, 2017.

Under the terms of the Amended Loan Agreement, the Company may borrow from time to time up to $200 million in revolving credit loans and other specified borrowings, subject to certain availability requirements. A portion of the credit facility is also available for letters of credit, with a sub-limit of $30 million outstanding at any time.

Maximum credit under the Amended Loan Agreement can be increased to $235 million at the request of the Company, if, among other things, the Company is not then in default. The Company also has the option to request an additional increase in the maximum credit to up to $300 million, subject to increases in lender commitments and certain other conditions.

Borrowings under the Amended Loan Agreement will bear interest at a rate determined by reference to the prime rate or LIBOR, at the Company’s option. The Amended Loan Agreement requires the Company to maintain a minimum Excess Availability of 10% of the Borrowing Base (as such terms are defined in the Amended Loan Agreement). Borrowings under the Amended Loan Agreement are secured by substantially all of the assets of the Company and its subsidiaries.

The Amended Loan Agreement contains representations, warranties, covenants and events of default that are customary for this type of financing.

The Company expects that borrowings under the Amended Loan Agreement will be used for working capital, general corporate purposes, and expenses and fees in connection with the Amended Loan Agreement.

The description in this Item 1.01 is qualified in its entirety by reference to the Amendment, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
