HOUSTON, April 4 /PRNewswire-FirstCall/ -- El Paso Natural Gas Company (EPNG), a wholly owned subsidiary of El Paso Corporation (NYSE: EP), announced today that it has determined the consideration to be paid in connection with its pending cash tender offer to purchase any and all of its outstanding 7 5/8% Notes due 2010 (CUSIP No. 283695BM5) and that it has received the requisite consents with respect to the related consent solicitation for the adoption of certain proposed amendments to the indenture governing the notes. The tender offer and the consent solicitation are subject to the terms and conditions set forth in EPNG's Offer to Purchase and Consent Solicitation Statement dated March 22, 2007 (the "Statement").

Holders who validly tendered (and did not validly withdraw) notes in the tender offer and validly delivered (and did not validly revoke) their corresponding consents in the consent solicitation at or prior to 5:00 p.m., New York City time, on April 4, 2007 will receive $1,043.73 per $1,000 principal amount of notes tendered, which is referred to in the Statement as the "Total Consideration," plus any accrued and unpaid interest from the last interest payment date for the notes to, but not including, the initial settlement date, which EPNG expects will occur tomorrow, April 5, 2007.

Holders who validly tender notes in the tender offer after 5:00 p.m., New York City time, on April 4, 2007 and at or prior to 12:00 midnight, New York City time, on April 18, 2007 will receive the total consideration set forth above minus the consent payment of $10.00 per $1,000 principal amount, which is referred to in the Statement as the "Purchase Price," plus any accrued and unpaid interest from the last interest payment date for the notes to, but not including, the final settlement date, which EPNG expects will occur on April 19, 2007.

The consideration to be paid in connection with the tender offer was determined by Citigroup Corporate and Investment Banking, the lead dealer manager for the tender offer, as of 2:00 p.m., New York City time, on April 4, 2007, as set forth in the Statement.

As of 5:00 p.m., New York City time, on April 4, 2007, $298,510,000 principal amount of notes had been validly tendered (and not validly withdrawn) together with related consents validly delivered (and not validly revoked). The consents delivered and not validly revoked as of such time constitute the consent of holders of approximately 84% of the outstanding notes, a percentage sufficient to amend the indenture as described in the Statement. The supplemental indenture incorporating the proposed amendments will become effective upon execution by EPNG and Wilmington Trust Company, as trustee, but will not become operative until the time that EPNG accepts for purchase notes representing the requisite consents, which EPNG expects to occur on the initial settlement date.

EPNG has retained Citigroup Corporate and Investment Banking to serve as lead dealer manager for the tender offer and lead dealer manager for the consent solicitation and has retained Global Bondholder Services Corporation to serve as the depositary and information agent for the tender offer.

The tender offer is made only by and pursuant to the terms of the Statement and the related letter of transmittal and consent. None of EPNG, the dealer managers or the depositary and information agent makes any recommendations as to whether holders should tender their notes pursuant to the tender offer. Holders must make their own decisions as to whether to tender notes, and, if so, the principal amount of notes to tender.
