ABL Facility Amendment

On April 8, 2014, Interline Brands, Inc., a New Jersey corporation (“Interline New Jersey”), Wilmar Financial, Inc. JanPak, LLC, JanPak of South Carolina, LLC, IBI Merchandising Services, Inc., each as a borrower, and Interline Brands, Inc., a Delaware corporation (“Interline”), Glenwood Acquisition LLC and Zip Technology, LLC, as additional loan parties, amended the asset-based senior secured revolving credit facility, dated as of September 7, 2012 (as amended, the “ABL Facility”), by entering into the Second Amendment to Credit Agreement, with Bank of America, N.A., as administrative agent, and the lenders party thereto (the “ABL Facility Amendment”). The ABL Facility Amendment amended certain pricing terms applicable to the ABL Facility and extended the maturity date of the ABL Facility to April 8, 2019.

As of the end of the quarter following the closing of the ABL Facility Amendment, the interest rates applicable to obligations under the ABL Facility will be determined as of the end of each fiscal quarter in accordance with applicable rates set forth in the grid below, which interest rates are generally 0.25% lower than the rates in effect prior to the ABL Facility Amendment:

From the date of the ABL Facility Amendment through the end of Interline New Jersey’s current fiscal quarter, the applicable rates for Category 2 will apply. The applicable rate for Category 1 will not be available until after the fiscal quarter ending on or about March 31, 2015. The applicable rates for Category 3 and, after March 31, 2015, Category 2, described above will be subject to a 0.25% step-down from the spread described above if the fixed charge coverage ratio for the period of four consecutive fiscal quarters ending on the last day of the fiscal quarter most recently ended is greater than 1.75:1.00.

The ABL Facility Amendment also revised the terms of the commitment fee payable by Interline New Jersey in respect of unutilized commitments, which will be equal to 0.375% per annum for the ABL Facility if utilization is less than 25% of the aggregate commitments and 0.25% per annum if the utilization of the ABL Facility exceeds 25% of the aggregate commitments.

Amendment to Pledge and Security Agreement

In connection with entering into the ABL Facility Amendment, Interline New Jersey and certain of its subsidiaries entered into a First Amendment to Amended and Restated Pledge and Security Agreement, dated as of April 8, 2014, with Bank of America, N.A., as administrative agent (the “Pledge and Security Agreement Amendment”) in respect of the ABL Facility.

The above description is only a summary of the terms of the ABL Facility Amendment and the Pledge and Security Agreement Amendment, and is qualified in is entirety by the actual terms of those agreements, copies of which are filed as Exhibits 10.1 and 10.2 to this Current Report on Form 8-K and is incorporated into this Item 1.01 by reference.
