Item 1.01 Entry into a Material Definitive Agreement

On May 15, 2012, NiSource Finance Corp. (“NiSource Finance”), as borrower, and NiSource Inc. (the “Company”), as guarantor, entered into an Amended and Restated Revolving Credit Agreement (the “Agreement”) with the lenders party thereto, Barclays Bank PLC, as Administrative Agent, Credit Suisse AG, Cayman Islands Branch, as Syndication Agent, The Bank of Tokyo-Mitsubishi UFJ Ltd., Citibank, N.A. and JPMorgan Chase Bank, N.A., as Co-Documentation Agents, and Barclays Bank PLC, Credit Suisse Securities (USA) LLC, The Bank of Tokyo-Mitsubishi UFJ, Ltd., Citigroup Global Markets, Inc. and J.P. Morgan Securities LLC, as Joint Lead Arrangers and Joint Bookrunners. The Agreement amends NiSource Finance’s existing $1.5 billion Revolving Credit Agreement to extend the term by approximately two years, from March 3, 2015 until May 15, 2017, and to reduce the applicable margin component of the interest rate calculation. Other than extending the term and reducing the applicable margin, the Agreement substantially restates the existing Revolving Credit Agreement.
