Company Urges ADS Holders To Vote FOR The Amendment To Raise The Endesa Shareholder Concentration Limit

CHARLOTTE – Duke Energy (NYSE: DUK) is reminding all Empresa Nacional de Electricidad SA (Endesa) American Depositary Shares (ADS) holders that they must sign, date and return their proxy to their broker or bank no later than Monday, April 5, to ensure their vote is counted in the Endesa shareholder vote on the bylaw amendment to raise the shareholder concentration limit from 26 percent to 65 percent.

"The vote of all ADS holders is extremely important," said Bruce Williamson, president and chief executive officer for Duke Energy International. "Duke Energy strongly urges all ADS holders to protect the value of their investment by voting FOR the bylaw amendment to raise the shareholder concentration and making sure their proxy is counted."

Voting FOR the amendment was recommended by Institutional Shareholder Services (ISS) in a March 29 report.

Duke Energy, through its wholly owned subsidiary Duke Energy International, has offered to purchase 51 percent of Endesa’s common shares, including common shares represented by American Depositary Shares at 250 Chilean pesos per share. The offer represents a premium of approximately 48 percent over the average price of Endesa shares for the six months prior to Duke Energy’s announcement of its offer. The offer cannot go forward unless the bylaw amendment is approved. The vote to amend the bylaws will occur at an extraordinary shareholders’ meeting to be held on April 8 in Santiago, Chile.

ADS holders’ banks or brokers must receive votes by April 5, 1999, in order to have ample time to deliver it to Citibank.

If you have any questions, or need last minute assistance in voting your ADS, please contact Innisfree M&A Incorporated at 1-888/750-5834 (toll-free) or 1-212/750-5833 (international collect).
