             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Participants and Administrator of
The El Paso Corporation Retirement Savings Plan:

In our opinion, the accompanying statement of net assets available for plan
benefits and the related statement of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
benefits of the El Paso Corporation Retirement Savings Plan (the "Plan") at
December 31, 2003 and 2002, and the changes in net assets available for benefits
for the year ended December 31, 2003 in conformity with accounting principles
generally accepted in the United States of America. These financial statements
are the responsibility of the Plan's management. Our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules listed in the
index on page 1 are presented for the purpose of additional analysis and are not
a required part of the basic financial statements but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. These supplemental schedules are the responsibility of the Plan's
management. The supplemental schedules have been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, are fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

                          NOTES TO FINANCIAL STATEMENTS


1.   DESCRIPTION OF PLAN

     The following description of the El Paso Corporation Retirement Savings
     Plan (the "Plan") provides general information about the Plan's provisions
     in effect for the plan year ended December 31, 2003. Participants should
     refer to the Plan documents and summary plan description for a more
     complete description of the Plan's provisions.

     General

     The Plan is a defined contribution plan covering eligible employees of El
     Paso Corporation (the "Company") and its participating employers, except
     leased employees, certain nonresident aliens, certain foreign nationals,
     and members of any unit covered by a collective bargaining agreement. The
     Committee for the Pension Plan, Retirement Savings Plan and Employees'
     Benefit Trust (the "Committee") is responsible for the general
     administration of the Plan as described in the Plan document. Until
     September 1, 2003, Deutsche Bank Trust Company Americas ("Deutsche Bank")
     was the trustee for the Plan. Effective September 1, 2003, State Street
     Bank and Trust Company ("State Street") became the trustee of the Plan.
     Hewitt Associates is the recordkeeper for the Plan. The Plan is subject to
     the provisions of the Employee Retirement Income Security Act of 1974, as
     amended ("ERISA").

     Contributions

     Prior to May 1, 2003, a participant could elect to make basic contributions
     from 2 percent to 15 percent on a before or after tax basis. Effective May
     1, 2003, a participant may elect to make basic contributions from 2 percent
     to 25 percent on a before tax basis and 2 percent to 15 percent on an after
     tax basis of his or her eligible compensation. The Company will make
     matching contributions in the same manner as that of participant
     contributions, equal to 50 percent of a participant's basic contribution up
     to a maximum level of 6 percent of eligible compensation.

     In addition, if a participant has elected the maximum basic contribution
     eligible for a matching contribution, he or she may make after-tax
     supplemental contributions to the Plan from 1 percent to 5 percent of his
     or her eligible compensation. A participant may also elect to have the
     amount of available cash under the Company's FlexPlan transferred to the
     Plan as a flex contribution or may make an approved rollover contribution
     of a distribution received or direct transfer from another qualified
     retirement plan. There are certain legal limitations, as provided by the
     Plan, applicable to contributions to the Plan. Federal income taxes on
     before-tax contributions, company matching contributions, and the earnings
     from the investments in the Plan are deferred until amounts are withdrawn
     from the Plan by participants.

     Participant Accounts

     Each participant's account is credited with the participant's
     contributions, the Company's matching contributions, the participant's
     share of net earnings or losses of his or her respective elected investment
     funds under the Plan and charged with an allocation of administrative
     expenses. Net investment gains and losses in a particular investment fund
     and administrative expenses are allocated in proportion to the respective
     participant account balances in that fund.

1.   DESCRIPTION OF PLAN (Continued)

     Vesting

     A participant's interest in the balance credited to his or her account is
     fully vested at all times.

     Payment of Benefits

     Upon separation from service with the Company, a participant whose account
     balance exceeds $5,000 may elect to receive either a lump-sum or
     installment distribution equal to the value of his or her account or to
     defer the distribution. A deferred distribution may take the form of either
     a lump-sum distribution payable within, or installments payable over, a
     period which ends on or before April 1 of the year following the calendar
     year in which the participant attains age 70-1/2. A participant whose
     account balance does not exceed $5,000 will receive an immediate lump-sum
     distribution of the amount equal to his or her account balance. Certain
     in-service withdrawals may also be available, as provided by the Plan.

     Participant Loans

     To obtain a loan, the participant must have a total account balance of at
     least $2,000 excluding any amounts held in an "IRA Rollover Account" under
     the Plan. Loan amounts may be from $1,000 to $50,000 but may not be more
     than 50 percent of the total balance in the participant's account,
     excluding any IRA Rollover Account balance. The 50 percent limit is reduced
     by the participant's highest outstanding loan balance(s) during the prior
     12-month period. Each loan is made from, and repaid to, the borrowing
     participant's account so as not to affect the accounts of other
     participants. A participant may not obtain more than one loan during any
     12-month period and may not have more than two loans outstanding. The
     interest rate on a loan is 1 percent above the prime rate, which is
     determined on the last business day of the month preceding the quarter in
     which the loan is taken. The interest rate is fixed for the term of the
     loan. Interest rates on participants loans from 5% to 10.5% in 2003 and
     5.75% to 10.5% in 2002. The repayment period may be from 1 to 5 years. When
     a participant terminates employment with the Company, the unpaid balance of
     the participant's loan(s) will be deducted from any distributions to the
     participant. If the participant elects to defer the distributions, the loan
     must be repaid within 60 days after separation from service. If the loan is
     not repaid, it will be automatically treated as a distribution to the
     participant.

1.   DESCRIPTION OF PLAN (Continued)

     Investment Options

     With exceptions as described below, a participant could direct the
     investment of his or her contributions to the Plan or reallocate the
     existing balance in his or her account among any one or more of the
     following investment funds during 2003. The diversification of securities
     within each investment fund is at the discretion of the fund manager. For a
     more complete description of the investment objectives, general information
     and performance history of the funds, participants should refer to the
     individual mutual fund prospectus and the summary plan description.

          1) Income Fund - invests primarily in a diversified portfolio of
     investment contracts offered by major insurance companies, banks and other
     financial institutions. The objective of the fund is to provide liquidity
     and safety of principal while providing a higher return over time than
     offered by money market funds. An investment contract is an agreement
     whereby the issuing entity promises a specific rate of return for a period
     of time. The contracts provide that a reduction in principal will not occur
     due to a change in interest rates. These contracts usually have maturity
     dates and interest rates that fluctuate to reflect the investment
     performance and activity of bonds that underlie the contract. However, like
     all of the Plan's investment funds, there is an element of risk. Some of
     the contracts are direct obligations of the issuing entity. To reduce the
     risk of the fund, most of the investment contracts are collateralized by
     fixed-income securities held in a separate account of an insurance company,
     or in a trust fund, to protect them from the general creditors of the
     contract issuer. The fund may also hold cash or other short-term fixed
     income securities, although these are expected to be a small percentage of
     the Income Fund. PRIMCO Capital Management, Inc. manages the Income Fund.

          2) Company Stock Fund - invests primarily in common stock of the
     Company (NYSE:EP). As with investments in any single stock, this fund may
     be more volatile (that is, subject to larger swings in value, both up and
     down) than a fund that is diversified among the stocks of many companies.
     Participants who invest in the Company Stock Fund may instruct the trustee
     regarding the voting of the Company's common stock allocated to the
     participant's account. The fund may also hold cash or other short-term
     fixed income securities, although these are expected to be a small
     percentage of the Stock Fund.

          3) Equity Index Fund - invests in an index fund designed to match the
     performance of the Standard and Poor's (S&P) Index by investing in stock of
     most of the 500 largest U.S. companies comprising that Index. This fund
     currently invests in a commingled fund for institutional investors known as
     the Daily Equity Index Fund T managed by Barclays Global Investors.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Accounting Basis

     The financial statements of the Plan are prepared on the accrual basis of
     accounting.

     Use of Estimates

     The preparation of the financial statements in conformity with accounting
     principles generally accepted in the United States of America requires
     management to make estimates and assumptions that affect the reported
     amounts of net assets available for plan benefits at the date of the
     financial statements, the reported changes in net assets available for plan
     benefits during the reporting period and disclosures related to the Plan.
     Actual results could differ from those estimates.

     Valuation of Investments

     For the Plan years ending December 31, 2003 and 2002, the Plan's investment
     contracts with financial institutions and insurance companies are reported
     at contract value, as they are benefit responsive investment contracts.
     Estimated fair value for investment contracts is based on discounted cash
     flows using current market rates for similar investments with similar
     terms. Short-term securities and participant loans are carried at cost
     which approximates fair value. All other investments are carried at fair
     value as determined by quoted market prices. Purchases and sales of
     securities are reflected on a trade-date basis. The basis of securities
     sold is determined by average cost.

     Amounts Due To Others

     Amounts due to others reflect the net unsettled securities bought and sold
     at year end.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES  (Continued)

     Investment Income

     Dividend income is recorded on the ex-dividend date. Interest income is
     recorded as earned on an accrual basis. Dividend and interest income is
     allocated to participants' accounts based upon each participant's
     proportionate share of assets in each investment fund. Dividend income
     represents income for those funds holding individual equity securities.
     Interest income represents income received from deposits with insurance
     companies, short-term securities and funds invested in commingled equity or
     mutual funds.

     Payment of Benefits

     Benefits are recorded when paid.

     Expenses

     Administrative expenses include participant recordkeeping and custodial
     fees, and certain professional fees incurred and paid by the Plan. In
     addition, any expenses directly relating to the purchase, sale, or transfer
     of the Plan's investments are charged to the particular investment fund to
     which the expense relates.

     Net Appreciation in Fair Value of Investments

     The Plan presents in the statement of changes in net assets available for
     plan benefits the net appreciation in the fair value of its investments
     which consists of the realized gains or losses and the unrealized
     appreciation (depreciation) on those investments.

     Risks and Uncertainties

     The Plan provides for various investment options in any combination of
     stocks, bonds, fixed income securities, mutual funds, and other investment
     securities. Investment securities are exposed to various risks, such as
     interest rate risk, market risk and credit risk. Due to the level of risk
     associated with certain investment securities, it is at least reasonably
     possible that changes in the values of investment securities will occur in
     the near term and those changes could materially affect the amounts
     reported in the statement of net assets available for plan benefits.

     Since November 2002, El Paso has undergone a series of downgrades of its
     credit ratings. The Company's senior unsecured debt is rated a "CCC+" by
     Standard and Poor's Rating Services as of February 18, 2004 and has
     remained unchanged by Moody's Investor Service at "Caa1" as of February 11,
     2003. The Committee does not believe these downgrades will impact the
     Company's ability to perform its obligations as Plan Sponsor.

4.   INVESTMENT CONTRACTS

     The Plan invests in a diversified portfolio of investment contracts as
     described in Note 1. The contracts are included in the financial statements
     at contract value as reported to the Plan by State Street. On December 31,
     2003 and 2002, the average yield for these investment contracts was 4.66
     percent and 5.46 percent, respectively, while the average crediting
     interest rate was 4.65 percent and 5.19 percent, respectively. Crediting
     interest rates are normally reset quarterly for contracts with underlying
     investments to reflect the investment experience of that asset. On December
     31, 2003 and 2002, the fair market value of the investment contracts were
     $246,005,686 and $263,466,869, respectively. There are no reserves against
     contract value for credit risk of the contract issuer or otherwise.

5.   CONCENTRATION OF CREDIT RISK

     The Plan invests in various investment funds, as described in Note 1, based
     upon participant instructions. The Income Fund held approximately 35
     percent and 43 percent of the invested assets of the Plan at December 31,
     2003, and 2002, respectively. The Company Stock Fund held approximately 24
     percent and 22 percent of the invested assets of the Plan at December 31,
     2003, and 2002, respectively. The Company believes that it offers
     sufficient investment options to allow participants to avoid any
     significant concentration of credit risk, although the ultimate control of
     investment diversification across the funds is up to the individual
     participant.

6.   RELATED PARTY TRANSACTIONS

     From January 1, 2003 to August 31, 2003, approximately $135 million and
     $134 million were purchased and sold, respectively, with Deutsche Bank in
     the BT Pyramid Directed Account Cash Fund. During this period,
     approximately 42 percent and 29 percent of the Plan's purchase and sale
     transactions, respectively, were related to these assets. During the period
     September 1, 2003 through December 31, 2003, approximately $50 million and
     $43 million were purchased and sold, respectively, with State Street Bank
     and Trust Company in the State Street Directed Account Cash Fund. During
     this period, approximately 40 percent and 33 percent of the Plan's purchase
     and sale transactions, respectively, were related to these assets.

7.   TAX STATUS

     The Plan is intended to be a qualified plan pursuant to Section 401(a) of
     the Internal Revenue Code of 1986, as amended (the "Code") and,
     accordingly, the trust established under the Plan to hold the Plan's assets
     is intended to be exempt from federal income taxes pursuant to Section
     501(a) of the Code. The Company received a favorable tax determination
     letter from the IRS on June 20, 2003 stating that the Plan, as designed,
     was in compliance with the applicable requirements of the Code. The Plan
     has been amended since receiving the determination letter. However, the
     Company believes that the Plan is currently designed and being operated in
     compliance with the applicable requirements of the Code. Therefore, no
     provision for income taxes has been included in the Plan's financial
     statements.

8.   AMENDMENTS AND FILINGS

     Effective March 1, 2003, the Plan was amended to suspend Company matching
     contributions. On May 14, 2003, the Company announced its intention to
     reinstate effective July 1, 2003 the Company's matching contribution in an
     amount equal to 50 percent of a participant's basic contribution up to a
     maximum level of 6 percent of eligible compensation.

     Effective May 1, 2003, the Plan was amended to allow for before-tax basic
     contributions in whole percentages from 2 percent to 25 percent of eligible
     compensation. The after-tax basic contribution limit remained unchanged at
     15 percent, and the supplemental after-tax contribution limit remained
     unchanged at 5 percent.

     Effective July 1, 2004, the matching contribution will increase to 75
     percent of a participant's basic contribution up to a maximum level of 6
     percent of eligible compensation.

9.   PLAN TERMINATION

     The Company reserves the right under the Plan to discontinue contributions
     at any time and to terminate the Plan subject to the provisions of ERISA
     and the Code. Upon termination, the Plan's assets would be distributed to
     the participants, as directed by the Committee in accordance with the Plan
     and applicable law, on the basis of their account balances existing at the
     date of termination, as adjusted for investment gains and losses.

10.  SUBSEQUENT EVENT

     Effective June 25, 2004, the El Paso Corporation Retirement Savings Plan
     Committee temporarily suspended future investments in the company stock
     fund under the Retirement Savings Plan until the company becomes current on
     its SEC filings. A notice to participants was distributed on June 25, 2004.

     Final distributions and participant withdrawals that have been processed
     and approved but not paid by the Plan are not considered Plan obligations
     until paid under generally accepted accounting principles, and therefore,
     are not presented as liabilities or benefits paid in the accompanying
     financial statements.
