INDEPENDENT AUDITORS' REPORT

Covanta Energy Americas, Inc.
The Power Savings Plan

We have audited the accompanying statements of net assets available for benefits
of Covanta Energy Americas, Inc. The Power Savings Plan (formerly Ogden Power
Corporation The Power Savings Plan), (the "Plan"), as of December 31, 2000 and
1999, and the related statements of changes in net assets available for benefits
for the years then ended. 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.

Except as explained in the following paragraph, 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 out audits provide a reasonable basis for our opinion.

As permitted by Section 2520.103-8 of the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974, investment assets held by Fidelity Management Trust
Company, the trustee of the Plan, and transactions in those assets were
excluded from the scope of our audit of the Plan's 1999 financial statements,
except for comparing the information provided by the trustee, which is
summarized in Note 9, with the related information included in the financial
statements.

Because of the significance of the information that we did not audit, we are
unable to express, and do not express an opinion on the Plan's financial
statements as of or for the year ended December 31, 1999. The form and content
of the information included in the 1999 financial statements, other than that
derived from the information certified by the trustees, have been audited by us
and, in our opinion, are presented in compliance with the Department of Labor's
Rules and Regulations for Reporting and Disclosure under the Employee Retirement
Income Security Act of 1974.

In our opinion, the financial statements, referred to above, of the Plan as of
December 31, 2000, and for the year then ended present fairly, in all material
respects, the net assets available for benefits of the Plan as of December 31,
2000, and the changes in net assets available for benefits for the year then
ended in conformity with accounting principles generally accepted in the United
States of America.

Our audit of the Plan's financial statements as of and for the year ended
December 31, 2000, was conducted for the purpose of forming an opinion on the
basic financial statements 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 supplemental schedule is the responsibility of the Plan's management.
Such schedule has been subjected to the auditing procedures applied in the audit
of the basic financial statements for the year ended December 31, 2000, and, in
our opinion, is fairly stated in all material respects when considered in
relation to the basic financial statements taken as a whole.

COVANTA ENERGY AMERICAS, INC. THE POWER SAVINGS PLAN
(formerly Ogden Power Corporation The Power Savings Plan)


NOTES TO FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2000 AND 1999

- --------------------------------------------------------------------------------


1.    DESCRIPTION OF THE PLAN

      The following description of the Covanta Energy Americas, Inc. The Power
      Savings Plan, (formerly Ogden Power Corporation The Power Savings Plan)
      (the "Plan"), provides only general information. Participants should refer
      to the Plan Document, a copy of which is available from the Plan
      administrator, for more complete information of the Plan's provisions.

      General - The Plan is a defined contribution plan covering substantially
      all employees of Covanta Energy Americas, Inc. (formerly Ogden Power
      Corporation) and its subsidiaries (collectively, "the Company"). The Plan
      is subject to the provisions of the Employee Retirement Income Security
      Act of 1974 (ERISA).

      Effective February 1, 2000, all of the assets and outstanding loans of the
      Plan were transferred from Fidelity Management Trust Company (the "Prior
      Trustee") to T. Rowe Price Trust Company (the "Trustee"). The Company,
      determined that it would be in the best interest of the Company and the
      Plan, for the assets and outstanding loans to be held by a separate
      trustee from the Prior Trustee.

      Eligibility - All employees of the Company who have attained age twenty
      and have completed three months of credited service are eligible to
      participate in the Plan. Qualified employees may enroll in the Plan only
      at the beginning of each quarter.


      Participant Contributions - A participant may contribute up to 15% of his
      or her eligible compensation to the Plan on a pretax basis. For 2000 and
      1999, participant pre-tax contribution could not exceed $10,500 and
      $10,000, respectively, in accordance with Internal Revenue Service ("IRS")
      Regulations.

      Employer Contributions - The Company matches 50% of a participant's pretax
      contributions with a maximum match equal to 3% of eligible compensation.
      Matching contributions are made each pay period, and there are no
      eligibility requirements. The Company may also make an annual
      discretionary profit-sharing contribution. The matching and profit sharing
      contributions follow the participants directed contributions into the
      various investment options offered by the Plan. Profit sharing
      contributions of $0 and $236,626 were made for the plan years 2000 and
      1999, respectively. These amounts were paid to the plan in the following
      year.

      Participant Rollover - Participants may make rollover contributions from
      other qualified employee benefit plans specified by the Internal Revenue
      Code (the "Code").

      Vesting - Participants are immediately vested in their voluntary
      contributions and matching Company contributions and earnings thereon.
      Employer discretionary contributions vest at 20% per year beginning with
      one year of service as defined in the Plan, with 100% vesting after five
      years of service.

      Payment of Benefits - Upon termination of service resulting from
      retirement, permanent disability, death, or termination of employment, a
      participant may elect to receive either a lump-sum amount equal to the
      vested value of his or her account, or annual installments over a period
      not exceeding five years.

      Forfeitures - Forfeiture amounts were used to reduce administrative
      expenses of the Plan. At December 31, 2000 and 1999, forfeitures of
      nonvested accounts totaled $9,857 and $26,277, respectively.

      Hardship Withdrawals - In certain hardship situations, as defined by the
      Plan, a participant can withdraw all or part of his or her vested pretax
      contributions account while still actively employed. Employer matching and
      discretionary contributions are not eligible for hardship withdrawals.

      In-Service Withdrawals - A participant who has attained the age of 59 1/2
      is permitted to withdraw upon request all or any portion of the account.

      Participant Loans - Participant loans are recorded at the face amount of
      the loans made to plan participants (see Note 5).

      Participant Accounts - Each participant's account is credited with the
      participant's contributions, the Company's matching contributions, and
      allocations of investment income and any Company discretionary
      contributions. Allocations of earnings are based on participant account
      balances. Allocations of discretionary contributions are based on eligible
      compensation.

      All contributions are allocated based on percentage elections made by each
      participant among the various mutual funds.

      During 2000, the Plan included the following funds in which participants
      could elect to invest their Plan assets:

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Basis of Accounting - The accompanying financial statements of the Plan
      have been prepared on the accrual basis of accounting.

      Investment Valuation - 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. Participant
      notes receivable are valued at cost, which approximates fair value.
      Purchase and sales of securities are recorded on a trade date basis.
      Dividends are recorded on the ex-dividend date.

      Investment Transactions - Investment transactions are accounted for on a
      trade-date basis.

      Investment Income - Dividend income is recorded on the ex-dividend date.
      Interest income is recorded on the accrual basis.

      Administrative Charges - Substantially all costs of administering the Plan
      were paid by the Company in 2000 and 1999. Certain mutual funds include
      direct investment management expenses that are paid by the Plan.

      Payment of Benefits - Benefits are recorded when paid.

      Use of Estimates - The preparation of financial statements in conformity
      with accounting principles generally accepted in the Unitded States of
      America requires management to make estimates and assumptions that affect
      the reported amounts of assets and liabilities at the date of the
      financial statements and the reported amounts of additions and deductions
      during the reporting period. Actual results could differ from those
      estimates.

      Accounting for Derivative Instruments - The Financial Accounting
      Standards Board issued Statement of Financial Accounting Standards
      ("SFAS") No. 133, Accounting for Derivative Instruments and Hedging
      Activities. SFAS No. 133, as amended and interpreted, established
      accounting and reporting standards for derivative instruments,
      including certain derivative instruments embedded in other contracts,
      and hedging activities. It requires entities, including employee
      benefit plans, to recognize all derivatives as either assets or
      liabilities in the statement of financial position and to measure
      those instruments at fair value. This Statement is effective for

3.    INVESTMENTS

      The following is a summary of the Plan's investments held by the Trustee
      at December 31, 2000 that represent 5% or more of the Plan's net assets:

                                                                           2000
      Investments at fair value determined by quoted market price:
        Fidelity Magellan Fund                                        $2,184,012
        T. Rowe Price Balanced Fund                                      701,400
        T. Rowe Price Blue Chip Growth Fund                            3,008,190
        T. Rowe Price New Horizons Fund                                  625,729
        U.S. Treasury Money Fund                                         561,891
        T. Rowe Price Equity Income Fund                               1,026,748
        T. Rowe Price Spectrum Income Fund                               609,336
      Investments at fair value estimated by the Trustee - Loan Fund     884,241

      The Stable Value Fund primarily invests in investment contracts providing
      a guaranteed return on principal invested over a specified time period.
      The crediting interest rates at December 31, 2000 for the various
      investment contracts ranged from 5.88% to 7.83%. The average yields of the
      Stable Value Fund for the year ended December 31, 2000 was 6.58%. 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.

      During 2000, the Plan's investments (including gains and losses on
      investments bought and sold as well as held during the year) depreciated
      in value by $637,405 as follows:

                                                                         2000

                                                                    $ (637,405)
                                                                    ===========

      Loans to participants which comprise the Loan Fund, are reported at cost,
      which approximates fair value.

4.    CONTRIBUTIONS RECEIVABLE

      The Plan recorded participant and employer contributions receivable at
      December 31, 2000 and 1999, for contributions related to the 2000 and 1999
      plan years, respectively, not yet received by the Plan at year-end. Such
      contributions were paid to the Trustee and allocated to participant
      accounts subsequent to the respective year-ends.

5.    PARTICIPANTS NOTES RECEIVABLE

      Participants may borrow from their accounts a minimum of $1,000 up to a
      maximum equal to the lesser of $50,000 or 50% of their vested account
      balance. Loan transactions are treated as a transfer (from) to the
      investment fund (to) from the Participant Loan Fund. The loans are for up
      to 5-year terms (10 years for the purchase of a principal residence) and
      are secured by the balance in the participant's account. The loans bear
      interest at one percent over the prime rate (9.5% to 10.5% and 9.5% to
      8.5% at December 31, 2000 and 1999, respectively) and are repaid ratably
      through payroll withholdings.

6.    EXCESS CONTRIBUTIONS REFUNDABLE

      The Plan is required to refund contributions to certain highly compensated
      participants in accordance with provisions of the Code. No excess
      contributions refundable were required or recorded at December 31, 2000
      and 1999.

7.    TAX STATUS

      The sponsor adopted a nonstandardized prototype plan which received an IRS
      opinion letter dated August 24, 1993, and the IRS has determined and
      informed the Company by letter dated January 20, 1998 that the Plan, as
      adopted, and related trust are designed in accordance with applicable
      sections of the Code. The Plan has been amended since receiving the
      determination letter. However, the Plan administrator believes that the
      plan is currently 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.    PLAN TERMINATION

      Although it has not expressed any intention to do so, the Company has the
      right under the Plan to discontinue its contributions at any time and to
      terminate the Plan subject to the provisions of ERISA. In the event of
      termination of the Plan, participants will become fully vested in their
      accounts.

9.    INFORMATION CERTIFIED BY THE TRUSTEE (UNAUDITED)

      The following is a summary of the unaudited information regarding the
      Plan, included in the Plan's 1999 financial statements, prepared by the
      Prior Trustee of the Plan, and furnished to the Plan administrator. The

      such information is complete and accurate.
