25 March 2004 - US energy supplier Dynegy Inc. announced Wednesday that its Board of Directors has decided to elect President, Chief Executive Officer and Director Bruce A. Williamson as Chairman of the Board. Mr. Williamson will replace Dynegy's non-executive Chairman of the Board, Daniel L. Dienstbier, who has announced his retirement and will not seek re-election at the Annual Meeting of Shareholders on May 20.

Dynegy also named Director Patricia A. Hammick as Lead Director, concurrent with Mr. Williamson's election to the Chairman position. The Board intends to name Mr. Williamson and Ms. Hammick to these positions following the annual meeting, should the company's shareholders re-elect them to serve as Directors for another year.

Mr. Williamson, 44, has served as President and Chief Executive Officer and as a Director of Dynegy since October 2002. In the broader role of Chairman, Mr. Williamson will provide leadership to the Board and its committees.

"The Board's unanimous decision to elect Bruce to this important position reflects our confidence in his abilities and the strength of our corporate governance structure," Mr. Dienstbier said. "Under Bruce's leadership, Dynegy has made outstanding progress in our self-restructuring plan, established a track record of delivering results, improved its capital structure and restored confidence and credibility with investors and the public. He will bring to the Chairman role the highest level of integrity, proven leadership capabilities and a strong commitment to create value for our investors."

Ms. Hammick, 57, was elected to the Board in April 2003. She has more than 25 years of energy industry experience, including management positions with Gulf Oil Exploration and Production, the National Gas Supply Association and Columbia Energy Group. In the new role of Lead Director, Ms. Hammick will preside over the regular executive sessions of Dynegy's independent Directors. She will also provide advice and counsel to the Chairman, work with the Chairman in developing Board meeting agendas and act as a liaison between the Board and the Chairman.

"Pat is a strong leader, a valuable asset to the Board and an instrumental contributor in the areas of compliance and corporate governance. Her extensive industry background also makes her the right choice for this role," Mr. Dienstbier said. "The Board will benefit from Pat's continued guidance and leadership."

Mr. Dienstbier, 63, has served as non-executive Chairman of the Board since October 2002 and as a Dynegy Director since 1995. He also served as interim Chief Executive Officer of Dynegy from May 2002 until Mr. Williamson's election in October 2002, directing the initial phase of Dynegy's self-restructuring plan. Mr. Dienstbier has planned his retirement since last year to provide for a less rigorous schedule and more time to devote to his family and a variety of interests.

"Dan provided invaluable counsel to our Board and the management team throughout the years and helped guide our company through some challenging times," Mr. Williamson said. "Dan served the company with the highest standards of ethics and professionalism, and Dynegy is fortunate to have benefited from his experience and expertise for nearly a decade."
