OPERATING AGREEMENT FOR

RECYCLE SOUTH, LLC

This Operating Agreement (this “Agreement”) is made and entered into by and between OmniSource Corporation (“OmniSource”), as the sole member of Recycle South, LLC, a Delaware limited liability company (“Company”) and the Company.

Preliminary Statement

Recycle South, LLC, a Delaware limited liability company, was organized on June 28, 2007, by the filing of a Certificate of Formation with the Delaware Secretary of State in the name South Atlantic Recycle Group, LLC. Thereafter, on August 31, 2007, pursuant to a Consolidation Agreement and Plan of Merger, South Atlantic Recycle Group, LLC merged with Atlantic Scrap & Processing, LLC, and changed its name to Recycle South, LLC (the “Merger”). In connection with the Merger, the Company’s equity owners, Carolina Investment Company, LLC (“Carolina”), ASAP Investors, LLC (“ASAP”) and CRG Investors, LLC (“CRG”), executed an Amended and Restated Limited Liability Company Operating Agreement of Recycle South, LLC (the “Initial Recycle South Operating Agreement”).

On June 9, 2008, Carolina purchased the equity interests in the Company held by ASAP and CRG, thereby becoming the sole member of the Company. The sole member terminated the Initial Recycle South Operating Agreement and entered into an Amended and Restated Operating Agreement for Recycle South, LLC to govern certain aspects of the operations of the Company and to set forth the rights and obligations of the successors and assigns (the “Prior Operating Agreement”).

Effective 11:59 p.m. on November 30, 2008, Carolina was merged with and into the Company, with the result that OmniSource Corporation became the sole member of the Company.
