ITEM 1. SUMMARY TERM SHEET Item 1 of the Exchange Offer is hereby amended and supplemented as follows: The ninth question and corresponding answer in the section of the Offering Memorandum titled "Questions and Answers About the Exchange Offer" is hereby restated in its entirety as follows: "Q: What are the conditions to the completion of the exchange offer? A: The exchange offer is conditioned on the receipt of a minimum number of equity security units as discussed above. The exchange offer is also subject to a limited number of additional conditions, some of which we may waive in our sole discretion. Most significantly, there must not be a reasonable likelihood that the exchange will result in the equity security units no longer being listed on the NYSE or otherwise be considered a "going private transaction." If any of these conditions are not satisfied, we will not be obligated to accept and exchange any tendered equity security units. Prior to the expiration date of the exchange offer, we reserve the right to amend the exchange offer in our sole discretion for any or no reason. We describe the conditions to the exchange offer in greater detail in the section titled "The Exchange Offer - Conditions to the Exchange Offer."" ITEM 4. TERMS OF THE TRANSACTION. Item 4 of the Exchange Offer is hereby amended and supplemented as follows: The section of the Offering Memorandum titled "Summary - The Exchange Offer - Consequences to Holders that Fail to Exchange Equity Security Units" is hereby restated in its entirety as follows: "Once the exchange offer is completed, any of your equity security units that are not tendered and exchanged in the exchange offer will remain outstanding in accordance with their terms. The conditions to our obligation to complete the exchange offer include the condition that there not be a reasonable likelihood that the exchange offer will cause the equity security units to be delisted from the NYSE." The section of the Offering Memorandum titled "Where You Can Find More Information" is hereby amended by adding the following to the end of the second paragraph thereof: "We are also incorporating by reference into this offering memorandum the following additional documents: * Current Reports on Form 8-K, dated December 4, 2003, December 9, 2003, and December 15, 2003." The section of the Offering Memorandum titled "The Exchange Offer - Conditions to the Exchange Offer - General Conditions" is hereby amended by deleting the fifth bullet point of the second paragraph thereof. The section of the Offering Memorandum titled "The Exchange Offer - Expiration Date; Extension; Modification; Termination" is hereby amended by deleting the fourth bullet point of the third paragraph thereof. ITEM 6. PURPOSES OF THE TRANSACTION AND PLANS OR PROPOSALS.

Item 12 of the Exchange Offer is hereby amended and supplemented as follows: The second paragraph of the Second Amended and Restated Letter of Transmittal is hereby restated in its entirety as follows: "El Paso reserves the right, at any time or from time to time, to extend the exchange offer at its discretion, in which event the term "expiration date" shall mean the latest date to which the exchange offer is extended. El Paso shall give notice of any extension by giving oral, confirmed in writing, or written notice to the exchange agent and by making a public announcement by press release prior to 9:00 a.m., New York City time, on the first business day after the previously scheduled expiration date. The term "business day" shall mean any day that is not a Saturday, Sunday or day on which banks are authorized by law to close in the State of New York."
