Item 1.01. Entry into a Material Definitive Agreement.

On December 30, 2005, Cinergy Corp. (the “Company”) entered into agreements with certain employees, including Michael J. Cyrus, Executive Vice President and Chief Executive Officer of the Commercial Business Unit, and James L. Turner, President, to accelerate the payment of a portion of the executive’s benefits, otherwise expected to be paid following the closing of the merger between the Company and Duke Energy (the “Merger”), in order to mitigate the Company’s taxes and related expenses. The agreements with Messrs. Cyrus and Turner amend their employment agreements, and benefit plans in which they participate, to provide that the Company will accelerate (into 2005) the payment of certain amounts that they have previously earned or are expected to earn following the closing of the Merger, which is anticipated to occur in the first half of 2006. In particular, the Company prepaid Mr. Cyrus $9,223,445 and Mr. Turner $589,680 in connection with some or all of the following benefits: (i) performance shares under the Company’s long-term incentive plan, (ii) expected 2006 bonus payment, (iii) estimated severance benefits, (iv) earned and vested supplemental executive retirement benefits and (v) restricted stock awards. In the event the executive voluntarily terminates his employment prior to the closing of the Merger, the executive is obligated to repay all of the payments, and if the Merger does not close on or prior to a specified date, the executive is obligated to repay half of the payments, to reflect his estimated tax liability upon receipt of the accelerated payments; in each case, less any amounts that the executive has already earned through such date. By accelerating these payments, the Company will mitigate its taxes and related expenses that it would otherwise incur if it had waited until after 2005 to make these payments.

Item 5.02. Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers.

On December 30, 2005, Mr. Cyrus informed the Company that he does not expect to continue his employment with the Company following completion of the Merger.
