HOUSTON, TEXAS, March 3, 2005—El Paso Corporation (NYSE:EP) announced today that it has closed the sale of the equity interests in its Cedar Brakes I and Cedar Brakes II subsidiaries to wholly owned subsidiaries of Arroyo Energy Investors LP, a Houston-based affiliate of The Bear Stearns Companies Inc. (NYSE:BSC), for cash proceeds of approximately $94 million. The purchase price was reduced from the previously announced $106 million by equity distributions of approximately $12 million received by El Paso in 2005.

As part of the closing, El Paso Marketing, L.P., El Paso's marketing subsidiary, has paid Constellation Energy Commodities Group, Inc. $240 million and transferred its obligations to supply power to the Cedar Brakes I and II entities to Constellation.

The sale eliminates approximately $575 million of associated non-recourse debt from El Paso's balance sheet as of December 31, 2004. The equity sale will result in a book loss of approximately $227 million, and El Paso will also realize an approximate $30 million loss in its trading book from the transfer of the contracts to Constellation, both of which will be reflected in El Paso's December 31, 2004 financial results.

This sale is part of El Paso's plan to sell its domestic power restructuring portfolio as part of its long-range plan to reduce the company's debt, net of cash, to approximately $15 billion by year-end 2005. To date, the company has announced or closed approximately $4.2 billion of asset sales. In addition, these announced or closed asset sales will eliminate approximately $1.6 billion of associated non-recourse debt from El Paso's balance sheet.
