INDEPENDENT AUDITORS' REPORT


Resource Recovery 401(k) Plan

We have audited the accompanying statements of net assets available for benefits
of the Resource Recovery 401(k) Plan (the "Plan") as of December 31, 2002 and
2001, and the related statement of changes in net assets available for benefits
for the year ended December 31, 2002. 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 in accordance with auditing standards generally accepted
in the United States of America. 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. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan at December 31, 2002
and 2001, and the changes in net assets available for benefits for the year
ended December 31, 2002 in conformity with accounting principles generally
accepted in the United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule listed in the
Table of Contents is presented for the purpose of additional analysis and is not
a required part of the basic financial statements, but is 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. This schedule is the responsibility of the Plan's management. Such
schedule has been subjected to the auditing procedures applied in our audit of
the basic 2002 financial statements and, in our opinion, is fairly stated in all
material respects when considered in relation to the basic financial statements
taken as a whole.

RESOURCE RECOVERY 401(k) PLAN

NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2002 AND 2001
- --------------------------------------------------------------------------------


1.    DESCRIPTION OF THE PLAN

      The following is a description of the Resource Recovery 401(k) Plan (the
      "Plan"). Participants should refer to the Plan document for more complete
      information.

      General Information - The Plan is a defined contribution employee savings
      plan providing for both employer and participant contributions. Prior to
      adoption of the Plan on January 1, 1999, Covanta Energy Services, Inc.
      (the "Company,") was included in the Ogden 401(k) Plan (the "Prior Plan").
      It was determined that it was in the best interest of the Company and its
      employees to adopt the Plan, such plan being substantially similar to, and
      a continuation of the Prior Plan. Accordingly, effective January 1, 1999
      the Prior Plan assets pertaining to the Company were transferred to the
      Plan. All service credited to an individual as a participant under the
      Prior Plan was credited to such individual under the Plan; provided, that
      such individual became a participant of the Plan on or after January 1,
      1999. The Plan is subject to the provisions of the Employee Retirement
      Income Security Act of 1974 ("ERISA").

      Administration of the Plan - Administrative and Investment Committees are
      appointed by the Board of Directors (the "Board") of Covanta Energy Group,
      Inc. ("CEG") and serve as fiduciaries of the Plan. The Administrative
      Committee has responsibility for administering the Plan and interpretation
      of the Plan.

      The Company's Investment Committee (the "Investment Committee") has
      responsibility for reviewing the performance of the Plan's investments.
      Costs related to the administration of the Plan may be paid out of Plan
      assets if the Company does not pay such expenses directly.

      On April 1, 2002, Covanta Energy Corporation ("Covanta") and 123 of its
      domestic subsidiaries, which include the Company, filed voluntary
      petitions for reorganization under Chapter 11 of the United States
      Bankruptcy Code (the "Bankruptcy Code") with the United States Bankruptcy
      Court for the Southern District of New York (the "Bankruptcy Court").
      Since April 1, 2002, thirty-one additional subsidiaries of Covanta filed
      for reorganization under Chapter 11 of the Bankruptcy Code. In addition,
      four subsidiaries, which had filed petitions on April 1, 2002, have been
      sold as part of the bankruptcy proceeding. It is possible that additional
      subsidiaries will file petitions for reorganization under Chapter 11 and
      be included as part of Covanta's plan of reorganization.

      Covanta and these subsidiaries, (collectively the "Debtors"), are
      currently operating their businesses as debtors in possession pursuant to
      the Bankruptcy Code. The Debtors dependence upon, among other things,
      confirmation of a plan of reorganization, their ability to comply with,
      and if necessary renew the terms of the Debtor in Possession Credit
      Facility, and their ability to generate sufficient cash flows from
      operations, asset sales and financing arrangements to meet their
      obligations, raise substantial doubt about their ability to continue as
      going concerns. The Debtors' Debtor in Possession Credit Facility includes
      provisions enabling Covanta and its subsidiaries, including the Company,
      to obtain funding for making employer matching contributions to the Plan.

      As a result of publicly disclosed information concerning Covanta and
      uncertainty of future rules and regulations which may apply to the Plan's
      investment in Covanta's common stock, the Investment Committee determined
      that it was in the best interest of the Plan and its participants to
      discontinue the Covanta Stock Fund as an investment option under the Plan
      effective March 18, 2002. Additionally, the Plan was amended to allow Plan
      participants to maintain their investment in the Covanta Stock Fund or, at
      their discretion, redirect their investment to another investment fund
      offered under the Plan. Also, on May 16, 2002, the Securities and Exchange
      Commission granted the application of the New York Stock Exchange, Inc.
      (the "NYSE") for removal of Covanta's common stock from listing and
      registration on the NYSE. The removal of such stock became effective at
      the opening of the trading session on May 17, 2002.

      The Investment Committee decided it was in the best interest of the Plan
      and its participants to terminate the Covanta Stock Fund effective as of
      the close of business on June 27, 2003. Participants are permitted to sell
      any or all of the Covanta Stock Fund held prior to that date. If a
      participant does not choose to sell their Covanta Stock Fund held prior to
      the close of business on June 27, 2003, all Covanta Stock Funds held in
      the participant's account will be sold and the proceeds will be deposited
      in the T. Rowe Price Stable Value Fund on the participants' behalf.

      Participation/Contributions - The Plan was amended, effective January 1,
      2002, to exclude from participation any employee who is eligible to
      participate in the newly adopted Covanta Energy Savings Plan (the "Savings
      Plan"). At that time, all active participants became participants of the
      Savings Plan. In addition, no participant who is eligible to participate
      in the Savings Plan is permitted to make an employee contribution or
      rollover contribution to the Plan and no employer contribution can be made
      with respect to participants who are eligible to participate in the
      Savings Plan. The Company intends to move existing account balances into
      the Savings Plan.

      Loans to Participants - Loans are made to participants at a minimum of
      $500 and up to the lesser of 50 percent of the participant's total vested
      account balance (including outstanding loans, if any,) minus the current
      loan balance or $50,000 reduced by the excess if any, of the highest
      outstanding balance of loans during the preceding 12 months, even if
      repaid over the outstanding balance of loans from Plan to the participant
      on the date on which such loan is made, not to exceed the limitations of
      the Tax Reform Act of 1986. The terms of the loans are a minimum of one
      year and a maximum of 5 years or 60 months (10 year maximum on loans for a
      primary residence). Participants were prohibited from borrowing funds
      accumulated in the Covanta Stock Fund. The maximum number of loans
      outstanding at one time for an employee is two loans with only one of the
      outstanding loans being a residential loan. The loan interest rate is
      based on the prime rate plus 1% on the first business day of each month.
      Loans to participants, which comprise the Loan Fund, are reported at cost,
      which approximates fair value.

      Vesting - On January 1, 2002, employer contributions became 100% vested
      for all active employees. Prior to January 1, 2002, the vesting of
      employer contributions was as follows:

                                                                        Percent
                 Years of Vesting Service in the Plan                   Vested

          Less than one year of vesting service                            0%
          One but less than two years of vesting service                  20
          Two but less than three years of vesting service                40
          Three but less than four years of vesting service               60
          Four but less than five years of vesting service                80
          Five or more years of vesting service                          100

      Participant contributions are immediately 100% vested.

      Retirement Dates - A participant's normal retirement date is the
      participant's sixty-fifth birthday. A participant may elect early
      retirement at age 55 with 5 years of credited service. A participant may
      also receive an earlier distribution from the Plan following a termination
      of employment. Any account with a balance of less than $5,000 will be
      automatically distributed following the participants termination of
      employment.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Basis of Accounting - The accounting and reporting policies followed in
      the preparation of the financial statements of the Plan are in conformity
      with accounting principles generally accepted in the United States of
      America.

      Investment Funds - Plan assets are held by T. Rowe Price Trust Company.
      All investments are participant-directed.

      Investment Valuation and Income Recognition - The Plan's investments are
      stated at fair value. Shares of mutual funds are valued at quoted market
      prices, which represent the net asset value of shares held by the Plan at
      year-end. Investments in the T. Rowe Price U.S. Treasury Money Fund are
      stated at cost plus investment income, which approximates fair value.
      Participant loans are valued at outstanding principle balance due for
      loans taken from individual accounts, which approximates fair value.
      Purchase and sales of securities are recorded on a trade date basis.
      Dividends are recorded on the ex-dividend date.

      Amounts for securities that have no quoted market prices represent
      estimated fair value. The approximate value of the Covanta Stock Fund is
      the quoted market price of Covanta's stock. The T. Rowe Price Stable Value
      Common Trust Fund ("Stable Value Fund") which invests in
      benefit-responsive investments and is valued at contract value (cost plus
      accrued interest), which approximates fair value.

      Distributions to Participants - Benefit payments to participants are
      recorded when paid.

      Use of Estimates - The preparation of 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 benefits and changes
      therein. Actual results could differ from the estimates and assumptions
      used.

      Risks and Uncertainties - The Plan provides for various investment options
      (Note 3). Investment securities, in general, are exposed to various risks,
      such as interest rate, credit and overall market volatility. Due to the
      level of risk associated with certain investment securities, it is
      reasonably possible that changes in value of investment securities will
      occur in the near term and that such changes would materially affect
      participants' account balances and the amounts reported in the statements
      of net assets available for benefits.

      Expenses - Administrative expenses of the Plan are paid by either the Plan
      or the Plan's sponsor as provided in the Plan document.

4.    INVESTMENT CONTRACTS

      The Stable Value Fund primarily invests in investment contracts providing
      a guaranteed return on principal invested over a specified time period.
      All investment contracts in the Stable Value Fund are fully
      benefit-responsive and are recorded at their fair values. Generally, fair
      value approximates contract value contributions made plus interest accrued
      at the contract rates less withdrawals and fees. If, however, an event has
      occurred that may impair the ability of the contract issuer to perform in
      accordance with the contract terms, fair value may be less than the
      contract value. The crediting interest rates at December 31, 2002 for the
      various investment contracts ranged from 3.34 percent to 7.83 percent. The
      average yield of the Stable Value Fund for the year ended December 31,
      2002 was 5.16 percent.

5.    PLAN TERMINATION

      On November 21, 2002, the Administrative Committee approved the merger of
      the Plan into the Savings Plan.

      The Plan has currently submitted a request under the IRS Voluntary
      Compliance Program (VCP). Upon approval, all participant account balances
      will be transferred to the Savings Plan. In absence of any assets, the
      Plan will cease to exist.

6.    FEDERAL INCOME TAX STATUS

      The Plan is currently being considered in a determination letter
      application submitted to the IRS of February 20, 2002. For the Plan years
      ended December 31, 1999, 2000 and 2001, the Company discovered operational
      compliance errors, which may impact the qualified status of the Plan. On
      August 26, 2002, the Company submitted a request for compliance statement
      with regards to the operations errors under the IRS's Voluntary Compliance
      Program available under Revenue Procedure 2002-47. The financial
      statements do not reflect any adjustment that may result from the
      resolution of the operational compliance errors with the IRS under the
      correction program.

7.    PARTY-IN-INTEREST TRANSACTIONS

      The Covanta Stock Fund invested in Covanta common stock which was traded
      on the New York Stock Exchange (the "Exchange") for 2001 and the first
      quarter of 2002, and on the National Quotation Bureau's Pink Sheets for
      the last three quarters of 2002.

      The Plan invests in certain mutual funds managed by the Trustee.

      Certain officers and employees of the Company (who may also be
      participants in the Plan) perform administrative services related to the
      operation, record keeping and financial reporting of the Plan. The Company
      pays these individuals salaries and also pays other administrative
      expenses on behalf of the Plan. Certain fees, including fees for the
      investment management services, to the extent not paid by the Company, are
      paid by the Plan.

      These transactions are not deemed prohibited party-in-interest
      transactions, because they are covered by statutory administrative
      exemptions from the Code's and ERISA's rules on prohibited transactions.
