CHARLOTTE, N.C. and CINCINNATI -- Paul M. Anderson, chairman of the board and
chief executive officer of Duke Energy, and James E. Rogers, chairman, president
and chief executive officer of Cinergy, announced today their selection of David
L. Hauser, currently group vice president and chief financial officer of Duke
Energy, to be the chief financial officer of Duke Energy when the companies
complete their merger in 2006. The selection is subject to the approval of the
board of directors of the new company once the merger is completed.

"As we integrate Duke Energy and Cinergy to create a platform for continued
growth, we thought it important to identify early the leader who would be
accountable for the new company's financial systems and controls," said Paul
Anderson. "Since being named CFO of Duke Energy in late 2003, David has done an
excellent job with our financial reporting, including creating greater
transparency and improving relations with the financial community. He's the
right leader to take on the important work of designing the financial systems
for the new Duke Energy," Anderson said.

"I've had the opportunity to work with David since the merger was announced in
May and have been impressed with his experience, his industry knowledge and his
business savvy," said Jim Rogers. "The new Duke Energy will participate in the
continued consolidation of the electric and gas industry, and David has the more
experience and strategic skills to be a key member of our leadership team,"
Rogers said.

A comprehensive integration process to merge Duke Energy and Cinergy will be
kicked off in mid-September. It is anticipated that the appointment of other key
executive and senior leadership positions will occur by the end of November
2005. The companies expect to close the merger in the first half of 2006. A more
precise closing window will be established following regulatory and shareholder

Hauser is a 30-year employee of Duke Energy. During his first 20 years with the
company, he held various accounting positions, including controller. He later
served as vice president, procurement services and materials. He was named
senior vice president of global asset development in 1997 and, in 1998, was
named senior vice president and treasurer.

A native of High Point, Hauser graduated from Furman (S.C.) University with a
bachelor of arts degree in business administration. He received a master of
business administration degree from the University of North Carolina at
Charlotte. He completed the Executive Program of Professional Management
Education at the University of North Carolina at Chapel Hill. He is a certified
