CINERGY, DUKE FILE MERGER APPROVAL APPLICATION IN OHIO

CINCINNATI – Cinergy Corp. (NYSE:CIN) and Duke Energy (NYSE:DUK) today filed an application with the Public Utilities Commission of Ohio seeking approval of their merger agreement by the end of 2005.

In the application, the companies said the transaction will be seamless for the customers of Cinergy’s Ohio subsidiary, The Cincinnati Gas & Electric Co., and creates a financially stronger organization that will continue CG&E’s long record of reliable electric and gas service to its customers at reasonable rates.  The combined company also pledges to continue to support economic development and philanthropic activities in its Ohio service area.

“Our Ohio customers will continue to experience high quality service, and we will continue to be a major participant in the community,” said Greg Ficke, president of CG&E.  “In the years after the transaction is completed, efficiencies and economies of scale from the larger company will provide benefits to both customers and shareholders.”

Cinergy and CG&E will continue to have a major presence in Cincinnati, which will continue to be the headquarters for Cinergy’s regulated operations in Ohio, Indiana and Kentucky, as well as the headquarters of CG&E.

The merger will have no effect on the regulation of gas and electric distribution service by the PUCO, and CG&E’s customer rates will continue to be set by the PUCO.  “This transaction will provide significant long-term benefits for CG&E’s customers and is in the public interest.  As demonstrated by the original Cinergy merger, we have a track record of delivering on the promises we make to the communities we serve, our regulators and other stakeholders,” said Ficke.

This is the first of several regulatory filings regarding the merger that will be made in the next several weeks and months at the state and federal level.
