DYNEGY COMPLETES REDEMPTION OF $400 MILLION

SERIES C CONVERTIBLE PREFERRED STOCK

Benefits include elimination of $22 million in annual preferred dividends and significant

reduction in diluted shares outstanding

HOUSTON (May 26, 2006) – Dynegy Inc. (NYSE: DYN) today announced that it has redeemed all of the outstanding shares of its Series C Convertible Preferred Stock (Series C preferred), which were held by Chevron U.S.A. Inc. (CUSA), a wholly owned subsidiary of Chevron Corporation (NYSE: CVX). After giving effect to the redemption, CUSA continues to hold 97 million shares of Dynegy’s Class B common stock, which represents an approximate 20 percent ownership interest in Dynegy based on the outstanding shares of Dynegy’s common stock as of May 19, 2006.

In order to redeem the Series C preferred, Dynegy paid CUSA $400 million in cash, plus accrued and unpaid dividends totaling $6.3 million. The company used approximately $176 million in net proceeds from an equity offering of 40.25 million shares of its Class A common stock that closed today (including net proceeds of $23 million from the underwriters’ exercise of their option to purchase an additional 5.25 million shares), with the balance funded from cash on hand.

“The redemption of the Series C preferred is accretive to all shareholders in cash flow and earnings per share through the elimination of the associated $22 million annual preferred dividend and the significant reduction in the number of diluted shares outstanding,” said Bruce A. Williamson, Chairman and Chief Executive Officer of Dynegy Inc. “In addition, by redeeming the Series C preferred at par, we have effectively addressed the last remaining security in our capital structure that had a coupon and also participated in the upside of our equity. As a result, under this simplified capital structure, all of the economic benefits beyond debt service from our continued strong power generation performance, higher commodity prices and future growth opportunities will now flow directly to our common stockholders.”
