*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	On January 2, 2007, Duke Energy Corporation ('Issuer') spun off its natural gas businesses to form the stand-alone company Spectra Energy Corp. As a result, equitable adjustments were made to Duke Energy's outstanding stock option awards.
(2)	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 multplying 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.
(3)	The reporting person was granted 10,000 stock options on December 14, 1999. The options became exercisable in five equal annual installments.
