HOUSTON, TEXAS, March 28, 2005—El Paso Corporation (NYSE:EP) announced today it has filed its 2004 Form 10-K with the SEC and has restated its 2002 financial results. The Form 10-K is available on the company's Web site, www.elpaso.com, on the Investors main page under El Paso Corporation Financial Filings and in the SEC Filings section.

As previously reported, during the completion of El Paso's financial statements for the year ended December 31, 2004, the company identified a potential error related to the manner in which it originally adopted the provisions of Statement of Financial Accounting Standards (SFAS) No. 141, Business Combinations, and SFAS No. 142, Goodwill and Other Intangible Assets in 2002. The potential error related to accounting for investments in certain unconsolidated affiliates acquired before July 1, 2001, where the fair value of these investments was greater than their original cost or acquisition price. As El Paso disclosed in its prior SEC filings, when the company originally adopted the new accounting standards in 2002, El Paso wrote off what it believed to be unallocated negative goodwill totaling $154 million as a cumulative effect of accounting change.

Impact on Prior Periods

Upon further review, El Paso has now determined that these amounts were not negative goodwill but rather amounts that should have been allocated to the long-lived assets of the underlying investments. As a result, El Paso restated its 2002 financial statements to reverse the cumulative effect amount of $154 million and further reflect the impact on unrealized losses and a related tax adjustment the company recorded on these investments in 2002. This change had no effect on the company's reported cash flows for any period.

Impact on 2004

Following the 2002 restatement and final closing adjustments, the financial results reported earlier this month should be adjusted as follows for the fourth quarter of 2004 and for year end 2004:
