The Board of Directors of Dynegy Inc. (NYSE:DYN - News) announced today that it
has accepted the resignation of Chuck Watson as Chairman and Chief Executive
Officer. The Board, at the unanimous request of the independent directors, has
appointed Glenn F. Tilton, Vice Chairman of ChevronTexaco and a Dynegy Director,
as interim Chairman. Board member Daniel L. Dienstbier, who is President of
Northern Natural Gas (NNG), has been appointed interim Chief Executive Officer.
The new officers assume their responsibilities effective immediately. Steve
Bergstrom is continuing with the Company as President and Chief Operating
Officer. Otis Winters will continue to serve as lead director of the Board.

Mr. Tilton said, "Chuck Watson played a critical role in the creation of the
merchant energy business and in the emergence of Dynegy as a major force in the
global energy industry. Under his leadership, the Company evolved from a small
enterprise into a top producer and marketer of energy."

Mr. Watson said, "For 17 years, I have endeavored to build value for all of our
stakeholders. Dynegy combines strategic assets, solid management and proven
strategies to navigate through the immediate challenges and meet the
opportunities ahead. As a shareholder, I fully support the combination of new
and existing leadership at this stage of the Company's evolution."

Mr. Tilton, continued, "Today, Dynegy is in an industry that is changing more
rapidly and profoundly than ever before. That change creates opportunities, as
well as a new set of challenges that must be addressed. In particular, events of
the past year have hurt the credibility of this sector and eroded investor
confidence. As a result, the changes in the merchant energy sector have been
extensive. Fortunately, Dynegy has a solid base of assets and strong business
fundamentals."

Mr. Dienstbier said, "I believe that we can move quickly and successfully to
address the issues Dynegy is now confronting. Glenn and I will work closely
together with Steve Bergstrom and the other talented and dedicated people here
toward resolving every issue facing the Company, realizing the value of Dynegy
and building for the future. We are committed to taking the actions necessary to
demonstrate to our investors, lenders and trading partners the underlying
strengths of this Company and its full potential."


Mr. Bergstrom said, "All of us at Dynegy are grateful for Chuck Watson's vision
and leadership in guiding the Company to tremendous success. The new structure
announced today will allow our team to focus fully on the key business and
operating issues before us. We appreciate the confidence of the Board and
ChevronTexaco in our ability to move the Company forward in this changed
environment."

Mr. Winters said, "In this environment, Dynegy must convince shareholders and
lenders that the company has the best strategy in place to resolve the issues it
faces, while generating new momentum in its businesses. We must move ahead
squarely focused on three objectives: restore the Company's credibility; build
on the strengths of our energy producing assets; and solidify our achievements
in energy marketing."

The Dynegy Board of Directors plans to conduct a comprehensive search to fill
the Chairman and CEO positions with a leader who has the right combination of
experience and skills to address all the opportunities and challenges facing the
Company as it moves forward.
