INDEPENDENT AUDITORS' REPORT

Ogden Projects Profit Sharing Plan

We have audited the accompanying statements of net assets available for benefits
of the Ogden Projects Profit Sharing 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.

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 as of December 31,
2000 and 1999, and the changes in net assets available for benefits for the
years then ended 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 2000 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.

OGDEN PROJECTS PROFIT SHARING PLAN

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

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


1.   DESCRIPTION OF THE PLAN

     The following is a brief description of the Ogden Projects Profit Sharing
     Plan (the "Plan"). Participants should refer to the Plan document for more
     complete information.

     a.   General Information - The Plan is a defined contribution employee
          savings plan providing for both employer and employee contributions.
          The Plan includes a pre-tax savings feature which is intended to
          qualify under Sections 401(k) and 401(a) of the Internal Revenue Code
          (the "Code"). Prior to January 1, 1998, the plan included an after-tax
          savings feature which was intended to qualify under Section 401(a) of
          the Code. The after-tax feature of the Plan was discontinued effective
          December 31, 1997 (see Note 2(j)). The Plan is intended to conform
          with the requirements of the Tax Reform Act of 1986 (TRA) and the
          Technical and Miscellaneous Revenue Act of 1988 (TAMRA). The Plan is
          subject to the provisions of the Employee Retirement Income Security
          Act of 1974.

     b.   Administration of the Plan - The Administrative Committee is appointed
          by the Board of Directors (the "Board") of Covanta Energy Group, Inc.
          ("CEG") (formerly Ogden Energy Group, Inc.) and serves as a fiduciary
          of the Plan. The Administrative Committee has general responsibility
          for the administration and interpretation of the Plan.

          The Covanta Energy Group Investment Committee is responsible for the
          appointment of investment advisors and reviewing the performance of
          the investment portfolio. Costs related to the administration of the
          Plan are paid by the participants out of Plan assets.

     c.   Participation - Each employee who was, as of December 31, 1988, a
          participant in the Plan continued to be a participant if they were
          employed by CEG on such date. Each other employee who performs an hour
          of service after December 31, 1988 becomes a participant on the first
          day of the month coinciding with or next following the earlier of: (i)
          the last day of a period of 6 months of continuous employment and (ii)
          the close of: (a) a twelve-month period if they had at least 1,000
          hours of service or (b) a Plan year during which they had at least
          1,000 hours of service.

     d.   Participants Accounts - Shares in group trust funds were determined on
          the basis of the initial asset contribution to the trust by each
          participating plan, adjusted for subsequent contributions,
          distributions and allocated income and realized and unrealized gains
          and losses. Allocation of income, realized and unrealized gains and
          losses, and administrative expenses were determined monthly on the
          basis of each plan's proportionate share in the plan assets stated at
          fair value.

     e.   Vesting - Vesting of employer contributions to the Plan is determined
          based on the period of vesting service by participants commencing on
          their date of hire to their date of termination of service in
          accordance with the following schedule:

                                                                         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.

     f.   Contributions - Contributions paid by CEG are determined by
          Compensation Committee of the Board. The Board's determination may be
          expressed in terms of a stated percentage of CEG's annual net profit,
          as a fixed dollar amount or as a percentage of total compensation paid
          to each participant. The contribution may not exceed the amount
          deductible by CEG for Federal income tax purposes and may be made only
          out of its current or accumulated earnings and profits. During 2001,
          the compensation committee of the Board approved a discretionary
          contribution for 2000 that is expected to be paid to the Plan in the
          second half of 2001. The 1999 discretionary contribution was made
          during 2000. The allocation of the contributions to individual
          participants is based on the relationship of compensation paid to each
          participant to the compensation paid to all participants. Participants
          may contribute one to ten percent of their annual compensation on a
          pre-tax basis. Participants direct the investment of their
          contributions into various investment options offered by the Plan.
          Participants direct the investment of their contributions into various
          investments options offered by the Plan. For 2000 and 1999,
          participant pre-tax contributions could not exceed $10,500 and
          $10,000, respectively, in accordance with Internal Revenue Service
          ("IRS") Regulations.

          Effective January 1, 1998, participants in the Plan may not elect to,
          nor continue to, make after-tax contributions to the Plan. Any
          after-tax contributions made by a participant on or before December
          31, 1997 and credited to his/her after-tax contribution account shall
          remain in such after-tax contribution account and will continue to be
          adjusted in accordance with the provisions of the Plan document

     g.   Distribution from the Plan because of Hardship - Withdrawals are
          permitted if a participant establishes, to the satisfaction of the
          Administrative Committee, a financial need for funds for which there
          is no other money available such as: (i) to purchase a primary
          residence, (ii) to pay uninsured medical expenses for the participant
          or immediate family, (iii) to prevent mortgage foreclosure on, or
          eviction from their primary residence, or (iv) to pay post-secondary
          educational expenses for the participant, spouse, children or
          dependents.

     h.   Payments from the Plan's Trust - The value of a participant's interest
          in the Plan is payable upon retirement, disability, death, or
          termination of employment, as follows:

          i)   Upon termination of service of a participant on or after
               retirement date or by reason of death or disability, an amount
               equal to the value of the participant's account as of the
               valuation date next following the date of termination of service,
               whether or not such participant has a vested interest in such
               account, is paid from the trust. Participants may elect to
               receive the distribution valued as of any month after the date of
               termination of service but not later than the April 1st of the
               year following the year the participant attains age 70-1/2.

          ii)  Upon the termination of service of any participant may be paid in
               a lump sum amount equal to the value, as of the valuation date
               coincident with or following the date of termination of service,
               of the vested interest, if any, in the account. Such payment is
               made to the participant as soon as practicable after termination
               of service. Participants may elect to receive the distribution
               valued as of any month after the date of termination of service
               but not later than April 1st of the year following the year the
               participant attains age 70-1/2.

               Any benefit payable under the Plan pursuant to (i) above is paid
               as one lump sum payment from the trust, with a supplemental
               payment to be made as promptly as possible in respect to any
               contribution allocated to the participant's account for the Plan
               year.

     i.   Loans - In accordance with Plan policy, participants can borrow
          against the vested portion of their account balance. Borrowings are
          limited to the lesser of $50,000 or 50% of the participant's vested
          balance (not to exceed certain limitations). While such loans do not
          represent a reduction of the participant's account balance,
          participants are prohibited from receiving allocations (earnings)
          based on the loan amounts, although when the loans are repaid, the
          interest expense incurred by the participant is added to the
          participant's account balance. The interest rate on such loans is the
          prime lending rate plus 1%.

     j.   Forfeitures - Forfeitures arising under the Plan during the year are
          allocated by the Administrative Committee to Participants' accounts in
          the same manner as contributions (see Note 1(f)).

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

          o    T. Rowe Price New Horizons Fund - This aggressive fund seeks high
               long-term growth. It invests in small-company stocks and takes a
               growth approach to investing. This fund is subject to the abrupt
               and unpredictable market movements associated with small-company
               stocks.

          o    Ogden Stock Fund - This fund invests in Covanta Energy
               Corporation (formerly Ogden Corporation) common stock, traded on
               the New York Stock Exchange.

          o    *T. Rowe Price Mid-Cap Growth Fund - This fund invests at least
               65% of its assets in a diversified portfolio of common stocks of
               mid-cap companies whose earnings T. Rowe Price expects to grow at
               a faster rate than the average company.

          o    *T. Rowe Price Science & Technology Fund - This fund invests at
               least 65% of its assets in the common stocks of companies
               expected to benefit from the development, advancement, and use of
               science and technology.

          o    T. Rowe Price Stable Value Fund ("Stable Value Fund") - This fund
               invests in investment contracts issued by high-quality insurance
               companies and banks.

          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 and
          1999 for the various investment contracts ranged from 5.88% to 7.83%
          and 5.88% to 8.41%, respectively. The average yields of the Stable
          Value Fund for the years ended December 31, 2000 and 1999 were 6.58%
          and 6.35%, respectively. 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 rate, 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.

     b.   Investment Valuation - Investments in securities listed on national
          securities exchanges are valued at closing composite prices published
          for the last business day of the year. Investments in guaranteed
          investment contracts included in the Stable Value Fund are stated at
          fair value, which approximates contract value. Investments in the U.S.
          Treasury Money Fund are stated at cost plus investment income which
          approximates fair value. Other investments are stated at fair value as
          determined by the Trustee.

     c.   Investment Transactions and Investment Income - Investment
          transactions are accounted for on the date purchases or sales are
          executed. Realized and unrealized gains and losses are determined
          based on the fair value of assets at the beginning of the Plan year.
          Dividend income is accounted for on the ex-dividend date. Interest
          income is recorded on the accrual basis as earned.

     d.   Distributions to Participants - Benefits are recorded when paid.

     e.   General - The financial statements are prepared in conformity with
          accounting principles generally accepted in the United States of
          America. These principles require management to make certain estimates
          and assumptions that affect the reported amounts of assets and
          liabilities at the date of the financial statements, and the reported
          amounts of changes in net assets available for benefits during the
          reporting period. Actual results could differ from those estimates.

     f.   Adoption of New Accounting Pronouncement - On September 15, 1999, the
          Accounting Standards Executive Committee issued Statement of Position
          99-3, Accounting for Defined Contribution Benefit Plan Investments and
          Other Disclosure Matters ("SOP 99-3"), which eliminates the previous
          requirement for a defined contribution plan to present investments by
          general type for participant-directed investments in the statement of
          net asset available for benefits, total number of units and the net
          assets value per unit during the period. SOP 99-3 is effective for
          plan years beginning after December 15, 1999. The Plan adopted SOP
          93-3 for the year ended December 31, 2000.

     g.   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, in June 1998. SFAS No. 133, as amended and interpreted,
          establishes 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 fiscal years after June 15, 2000. Management has
          determined that the implementation of SFAS No. 133 will have no effect
          on the Plan's financial statements.

3.   INVESTMENTS

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

4.   PLAN TERMINATION

     The Board or the Administrative Committee may amend the Plan at any time.
     No such amendment, however, may have the effect of diverting to CEG any
     part of the Plan or of diverting any part of the Plan for any purpose other
     than for the exclusive benefit of the participants. Likewise, an amendment
     may not reduce the interest of any participant in the Plan accrued prior to
     such amendment. The Board or the Administrative Committee may, however,
     make such amendments to the extent required to conform the Plan to ERISA or
     to maintain the continued qualified status of the Plan under the Code.

     CEG expects to continue the Plan indefinitely, but reserves the right to
     suspend contributions or to modify or terminate the Plan at any time. Upon
     termination of the Plan or discontinuance of contributions thereunder, the
     interest of each participant is fully vested and nonforfeitable.

5.   TAX STATUS

     The Plan and trust is intended to be qualified under Section 401(a) and tax
     exempt under Section 501(a) of the Code, respectively. The Plan received a
     favorable determination letter from the IRS dated June 16, 1995. However,
     the Plan has been amended since receiving the determination letter. The
     Plan Administrator 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.
