Item 1.01 Entry into a Material Definitive Agreement

As previously announced, on June 10, 2013, Exide Technologies (the “Company”) filed a voluntary petition (the “Chapter 11 Case”) for relief under Chapter 11 of Title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”).

On November 17, 2014, the Company filed with the Bankruptcy Court (1) a proposed plan of reorganization (as may be amended, modified or supplemented from time to time, the “Proposed Plan”) and (2) a related proposed disclosure statement (as may be amended, modified or supplemented from time to time, the “Proposed Disclosure Statement”). The Proposed Plan is consistent with that certain plan support agreement (as amended from time to time, the “PSA”) entered into by and among the Company and the holders of a majority of the outstanding principal amount of the Company’s senior secured notes on November 4, 2014.

On January 7, 2015, in accordance with the PSA, the Company entered into a backstop commitment agreement (the “BCA”) with certain of its senior secured noteholders (the “Backstop Parties”). Pursuant to the BCA, and subject to the terms and conditions thereof, the Backstop Parties have agreed to purchase up to $160 million of $175 million new second lien convertible debt in the reorganized company to be offered in a rights offering under the Proposed Plan (the “Rights Offering”).

In connection with the Company’s entry into the BCA, the Company and the holders of a majority of the principal amount of the Company’s senior secured notes also amended and restated the PSA on January 7, 2015, memorializing support for the Company’s Proposed Plan.

The foregoing description of the BCA and the amended and restated PSA does not purport to be complete and is qualified in its entirety by reference to the text of such documents, which are filed as Exhibits 10.1 and 10.2 hereto and are incorporated by reference herein.

On January 7, 2015, the Company issued a press release regarding the BCA. The press release is attached as Exhibit 99.1 to this report.
