Explanation of Responses:

1. On April 3, 2006, Cinergy Corp. ('Issuer') merged into a wholly-owned subsidiary of Duke Energy Holding Corp. (now known as Duke Energy Corporation) ('Duke Energy'). In connection with the merger, each share of Issuer's common stock was converted into the right to receive 1.56 shares of Duke Energy's common stock and each stock option of Issuer was converted by multiplying the number of Issuer shares previously covered by the option by 1.56 and dividing the prior exercise price of the option by 1.56.

2. The derivative security converts into common stock on a one-for-one basis.

3. Generally payable upon reporting person's termination of service.

4. The reporting person was granted 10,000 stock options on December 14, 1999. The options became exercisable in five equal annual installments.
