Duke Energy Forms Joint Venture with Alinda Capital Partners

to Grow DukeNet Communications

CHARLOTTE, N.C. — Duke Energy, Alinda Capital Partners LLC and DukeNet Communications today announced the formation of a joint venture to grow DukeNet.

An affiliate of Alinda will acquire 50 percent of the ownership interests in DukeNet from an affiliate of Duke Energy in exchange for $137 million in cash. Duke Energy, through its affiliate, will continue to own the remaining 50 percent in DukeNet.

“We are pleased to partner with Duke Energy and DukeNet to provide critical telecommunications infrastructure in the southeastern U.S.” said Alinda Managing Partner Chris Beale. “We like DukeNet’s strong competitive position and its strategy to meet rapidly growing demand for transmission of data.”

“This transaction demonstrates DukeNet’s value to the telecommunications market in North Carolina, South Carolina, Tennessee and Georgia, and it speaks to the quality of our networks,” said DukeNet president Brad Davis.

“Duke Energy and Alinda Capital Partners bring complementary strengths to this joint venture,” said Keith Trent, group executive and president of Duke Energy’s Commercial Businesses. “With Alinda, we’ll take DukeNet to the next level in southeastern U.S. markets.”

Brad Davis will remain President of DukeNet and his management team will continue to run the joint venture’s day-to-day operations.

The deal is expected to close in the third quarter of 2010.
