Item 2.01. COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS

         On September 30, 2004, we completed the sale of our ownership interests
in GulfTerra Energy Partners, L.P. ("GulfTerra") and nine processing plants in
South Texas to affiliates of Enterprise Products Partners, L.P. ("Enterprise").
The sales were completed in connection with the closing of the merger between
GulfTerra and Enterprise. On October 7, 2004, we filed a Current Report on Form
8-K to provide the proforma financial impacts of the sales on our historical
financial statements. The periods included in that filing were based on the most
recent financial information available on that date. This Current Report on Form
8-K/A is being filed to provide updated financial information on the proforma 
impacts of these sales. 

Item 9.01.  FINANCIAL STATEMENTS AND EXHIBITS

b. Unaudited Pro Forma Financial Statements

         The accompanying unaudited pro forma financial statements are based on
our historical consolidated financial statements as of and for the six months
ended June 30, 2004, and for the year ended December 31, 2003, adjusted for the
effects of the sales of our interests in GulfTerra and the processing plants
described above. The unaudited pro forma balance sheet as of June 30, 2004,
assumes these dispositions occurred on the balance sheet date. The unaudited pro
forma statements of income for the six months ended June 30, 2004, and for the
year ended December 31, 2003, assume these dispositions occurred on January 1,
2003. The unaudited pro forma financial statements should be read in conjunction
with the historical consolidated financial statements included in our Quarterly
Report on Form 10-Q for the six months ended June 30, 2004, and our Annual
Report on Form 10-K for the year ended December 31, 2003, and should not be
construed to be indicative of future results or results that actually would have
occurred had the transactions occurred at the dates presented. In addition,
these pro forma financial statements were prepared in accordance with Article 11
of Regulation S-X. Accordingly, we have not made any assumptions or adjustments
for possible increases or decreases in distributions to us from Enterprise or
assumed any cost savings or synergies that might occur related to these
transactions.

                   NOTES TO THE UNAUDITED PRO FORMA CONDENSED
                        CONSOLIDATED FINANCIAL STATEMENTS


EL PASO HISTORICAL

         These amounts represent our condensed historical consolidated balance
sheet and income statement information. Amounts as of and for the six months
ended June 30, 2004 were derived from our Quarterly Report on Form 10-Q for the
six months ended June 30, 2004. Amounts for the year ended December 31, 2003
were derived from our 2003 Annual Report on Form 10-K.


PRO FORMA ADJUSTMENTS

         These amounts represent the historical results and balances related to
certain of our interests in GulfTerra which were accounted for as equity
investments and the nine processing plants sold to Enterprise as of and for the
periods presented. The pro forma adjusting entries reflect the following
transactions:

     o    The sale of all of our interest in the general partner of GulfTerra, 
          which includes the elimination of a minority ownership in the general
          partner that arose from the interest previously sold to Enterprise in
          December 2003;
     o    The redemption of our Series B units of GulfTerra which occurred in
          October 2003;
     o    The elimination of all effects of our common units and Series C units
          of GulfTerra, with the exception of the amounts related to the units
          retained by us; and
     o    The elimination of all non-affiliated effects of the nine processing
          plants sold.

PRO FORMA ADJUSTING ENTRIES

(a)   To reflect the pro forma effects of the sale of our GulfTerra interests
      and South Texas processing assets on our consolidated balance sheet. The
      pro forma effects include the following:

        (1)  Receipt of net proceeds of $1.02 billion from the sale of all
             of our interest in the general partner of GulfTerra, 10.9 million
             Series C units, 2.9 million common units, nine processing plants in
             South Texas, and the receipt of 9.9 percent interest in the general
             partner of the combined organization that has an estimated fair
             value of $81 million. 
        (2)  Elimination of our net investment in GulfTerra of $411 million.
        (3)  Elimination of goodwill included in our Field Services segment of
             $480 million as a result of the completion of the sale and $181 
             million of intangible assets associated with the assets sold.
        (4)  Elimination of a portion of the previously deferred gains on prior
             transactions with GulfTerra of $88 million ($84 million of which
             was included in non-current liabilities).
        (5)  Elimination of minority interest of $84 million related to the
             previous sale of an effective 50 percent general partner interest
             in GulfTerra to Enterprise in December 2003.
        (6)  Elimination of the carrying value as of June 30, 2004 of the nine
             South Texas processing plants which were classified as assets held
             for sale of $143 million, $12 million of inventory, $10 million
             of related liabilities and $8 million of other current assets, in 
             addition to an accrual of $1 million of selling costs.
        (7)  Recording a $121 million net loss associated with the sale
             transaction. The amount consists of a $27 million pretax gain on
             the sale and income taxes of $148 million related to the 
             non-deductibility for tax purposes of goodwill eliminated in the 
             sale transaction.
        (8)  Sale of property, plant and equipment in the amount of $14
             million used by general and administrative staff in support of
             GulfTerra operations, and accrual of $8 million in selling costs.

                                      -6-

(b)   To reflect the pro forma effects of the sale of our GulfTerra interests
      and South Texas processing assets on our consolidated income statements.
      The pro forma effects include the following:


        (1)  Adjustment for the historical results of operations for our South
             Texas Processing Plants, including impairment charges recorded
             during 2003 and 2004 on these assets;

        (2)  Reduction of earnings from unconsolidated affiliates for (i) our
             general partner interests, (ii) all Series C units, (iii) all
             Series B units redeemed by GulfTerra during 2003, and (iv) the
             proportional share of income on GulfTerra common units sold; and

        (3)  Elimination of gains (losses) recorded in earnings from
             unconsolidated affiliates during 2003 and 2004 on sales of our
             GulfTerra interests, including the gain on the sale of an effective
             50 percent general partner interest to Enterprise; realized gains
             in 2003 on our sale of GulfTerra common units; and a realized loss
             on GulfTerra's redemption of our Series B units in 2003.

(c)   To reflect income taxes related to income statement adjustments at a 
      statutory tax rate of 35 percent, which is different from our effective
      tax rate.


                                      -7-
