Duke Energy directors to be named to the board of the new company are Paul M. Anderson (to be chairman of the board), Roger Agnelli, William Barnet III, G. Alex Bernhardt Sr., William T. Esrey, Ann Maynard Gray, James H. Hance Jr., Dennis R. Hendrix, Michael E.J. Phelps and James T. Rhodes. Current Duke Energy directors James G. Martin and Max Lennon were both scheduled to retire from the board concurrent with the 2006 annual meeting. However, their retirements will be accelerated to coincide with completion of the merger.


“This special shareholder meeting to consider the combination of Duke Energy and Cinergy will be an important milestone as we move to wrap up our remaining approvals,” said Anderson, chairman and chief executive officer of Duke Energy. “While I’m excited about the group of directors who will represent the shareholders of the new company, our retiring directors, Jim Martin and Max Lennon, deserve much thanks and appreciation for their years of dedicated service and steadfast commitment to Duke Energy.”


Cinergy directors to be named to the board of the new company are James E. Rogers (to be president and chief executive officer of the new Duke Energy), Michael G. Browning, Phillip R. Cox, Mary L. Schapiro and Dudley S. Taft. Four current Cinergy directors, George Juilfs, Tom Petry, Jack Schiff and Phil Sharp, will not serve on the board of the new Duke Energy.







"I cannot thank these directors enough for their years of dedicated and outstanding service to Cinergy and its shareholders," said Rogers, Cinergy chairman and chief executive officer. "I will miss their invaluable advice and wisdom."


The special meetings of shareholders follow a number of regulatory merger approvals. In December 2005, the Federal Energy Regulatory Commission and the Public Utilities Commission of Ohio both approved the planned combination. In November 2005, regulators in South Carolina and Kentucky approved the

merger. And in August 2005, the companies satisfied Federal Trade Commission/ and U.S. Department of Justice review under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.


The merger remains subject to other closing requirements including approvals from the Nuclear Regulatory Commission. State regulators in North Carolina and Indiana are currently considering settlement agreements reached between the companies and certain interested parties in each state.  


Each company’s shareholders of record at the close of business on Jan. 17, 2006, will be mailed the definitive proxy materials in connection with the proposed merger and will be entitled to vote at the special meeting of shareholders. As a result of the merger, both the Duke Energy and Cinergy annual meetings, normally held during May, will be postponed. The first annual meeting of the new Duke Energy is expected to be held later in the year.
