Duke Energy to Offer Public a Unique Investment Opportunity

CHARLOTTE — Duke Energy today launched PremierNotesSM, a notes program that provides individuals and other qualified investors an opportunity to make direct investments in new debt of the corporation.

PremierNotes will pay a floating rate of interest that provides a competitive alternative to other short-term cash investments such as bank accounts and short-term Certificates of Deposit (CDs).

The interest rate for PremierNotes will be set at least a quarter of a percentage point higher than the average rate of taxable U.S. money-market mutual funds, based on published weekly rates.

“The PremierNotes program provides Duke Energy with an additional source of liquidity and a diversification of its capital funding,” said Stephen G. De May, senior vice president, investor relations and treasurer. “Although the funds are not Federal Deposit Insurance Corp. (FDIC) insured, they are direct obligations of Duke Energy, one of the largest electric power holding companies in the United States. Each investor should

consult a financial advisor to determine whether PremierNotes is the right investment for meeting individual financial objectives.”

Persons who invest with the minimum required balance of $1,000 will receive convenient services such as free check-writing and transfers to and from linked checking accounts. There are no maintenance fees or check fees for redemption checks of $250 or more and PremierNotes investments are fully redeemable on demand. The maximum total investment allowed per investor is $250,000.

Under the program, Duke Energy will use the net proceeds from the sale of the notes for general corporate purposes, which may include capital expenditures and the repayment of other debt.

PremierNotes materials can be downloaded at www.duke-energy.com/premiernotes, or by calling 800-659-DUKE (3853). Representatives will be available Monday through Friday from 8:30 a.m. to 5 p.m. ET, except holidays.
