HOUSTON, TX--(Marketwire - March 17, 2011) - El Paso Corporation (NYSE: EP) today announced the commencement of cash tender offers to purchase the seven series of its outstanding senior notes listed in the table below. The specific terms and conditions of the tender offers are described in the Offer to Purchase dated March 17, 2011. The tender offers will expire at 11:59 p.m., New York City time, on April 13, 2011 (such date and time, as it may be extended, the "Expiration Date").

______________________________________
(1) Per $1,000 principal amount of Notes tendered and accepted for purchase.
(2) Includes the Early Tender Payment.
(3) The 9.625% Senior Debentures were originally issued by El Paso CGP Company, L.L.C. (f/k/a The Coastal Corporation). The Company offered its 9.625% Senior Notes (CUSIP No. 28336LAZ2) in exchange for the 9.625% Senior Debentures, which exchange offer was consummated on December 28, 2005. The principal amount of 9.625% Senior Debentures that remains outstanding under CUSIP No. 190441AP0 was not exchanged pursuant to the exchange offer and were assumed by the Company on December 31, 2005.
(4) The 7.875% Senior Notes were originally issued by the Company in a Rule 144A transaction. The principal amount outstanding under CUSIP No. 28336LAD1 did not participate in the related registered exchange offer. The principal amount outstanding under CUSIP No. 28336LAE9 reflects 7.875% Senior Notes that did participate in the exchange offer.

Upon the terms and subject to the conditions described in the Offer to Purchase, El Paso is offering to purchase for cash:

• any and all of the three series of notes identified as Any and All Notes in the table above; and
• the four series of notes identified as Maximum Tender Offer Notes in the table above.

El Paso is offering to purchase the Maximum Tender Offer Notes such that the aggregate amount of the consideration (excluding accrued interest and fees and expenses) paid for the Maximum Tender Offer Notes tendered is equal to $470,000,000 less the aggregate amount of the consideration (excluding accrued interest and fees and expenses) paid for the Any and All Notes tendered and accepted for purchase (the "Maximum Tender Offer Amount"). El Paso reserves the right to increase the Maximum Tender Offer Amount, without extending withdrawal rights, subject to compliance with applicable law.

If the aggregate amount of the consideration to be paid for the Maximum Tender Offer Notes validly tendered is greater than the remaining Maximum Tender Offer Amount, the principal amount of Maximum Tender Offer Notes to be purchased will be accepted for purchase on a prorated basis.

If proration is required, each holder will have a fraction of the principal amount of tendered Maximum Tender Offer Notes purchased, rounded down to the nearest integral multiple of $1,000. The proration factor shall be a fraction, the numerator of which is the Maximum Tender Offer Amount and the denominator of which is the aggregate amount of the consideration for all Maximum Tender Offer Notes that have been validly tendered prior to the Expiration Date.

Holders of Notes that are validly tendered and not validly withdrawn on or prior to 5:00 p.m., New York City time, on March 28, 2011 (such time, as it may be extended, the "Early Tender Date") and that El Paso accepts for purchase will receive the applicable total consideration as specified in the table above (the "Total Consideration"), which includes the applicable early tender payment as specified in the table above (the "Early Tender Payment"). Holders of Notes that are validly tendered after the Early Tender Date but on or prior to the Expiration Date and that El Paso accepts for purchase will receive only the applicable Tender Offer Consideration. The applicable Tender Offer Consideration is equal to the applicable Total Consideration minus the applicable Early Tender Payment.

Holders who tender Notes on or prior to 5:00 p.m., New York City time, on March 28, 2011 (such date and time, as it may be extended, the "Withdrawal Deadline") may withdraw such tendered Notes at any time on or prior to the Withdrawal Deadline. Following the Withdrawal Deadline, holders who have tendered their Notes (whether before, on or after the Withdrawal Deadline) may not withdraw such Notes, unless El Paso is required to extend withdrawal rights under applicable law.

Payments for any Notes purchased by El Paso will include accrued and unpaid interest from and including the last interest payment date up to, but not including, the applicable settlement date.

El Paso may, at its option, accept for payment Any and All Notes validly tendered and not validly withdrawn on or prior to the Early Tender Date at any time after the Early Tender Date and prior to the Expiration Date (an "Early Acceptance Date"). If El Paso elects to have an Early Acceptance Date, the Early Acceptance Date may be as early as March 29, 2011, the first business day after the Early Tender Date. In such event, El Paso expects to purchase the Any and All Notes tendered on or prior to the Early Tender Date at a time promptly following early acceptance.

Payment of the applicable Tender Offer Consideration (and for Notes validly tendered on or prior to the Early Tender Date, the applicable Early Tender Payment) with respect to Notes that are validly tendered on or prior to the Expiration Date and are accepted for purchase (and not already purchased pursuant to early acceptance) will be made on the final settlement date, which is expected to be on April 14, 2011, the first business day following the Expiration Date.
