at 9:30 a.m. (Eastern Daylight Saving Time) at the Essex House hotel, 160

card for this Annual Meeting is enclosed. This Proxy Statement and the
accompanying proxy card are first being sent to shareholders on or about
April 20, 2001.

The purposes of the Annual Meeting are:

(1) To elect four directors to hold terms of office expiring at the Annual
    Meeting of Shareholders in 2004 and until their respective successors have
    been elected and qualified;

(2) To ratify the appointment of Deloitte & Touche LLP as auditors of Covanta
    and its subsidiaries for the year ending December 31, 2001;

(3) To consider and act upon a proposal made by a shareholder to "urge the Board
    of Directors to obtain prior shareholder approval for all future agreements
    that provide compensation for senior executives if there is a change in
    control of the Company"; and

(4) To consider and act upon such other business as may properly come before
    this Annual Meeting.

    The solicitation of proxies to which this Proxy Statement relates is made by
and on behalf of the Board of Directors of Covanta. The costs of this
solicitation will be paid by Covanta. Such costs include preparation, printing
and mailing of the Notice of Annual Meeting, proxy cards and Proxy Statement.
The solicitation will be conducted principally by mail, although directors,
officers and employees of Covanta and its subsidiaries (at no additional
compensation) may solicit proxies personally or by telephone and telegram.
Arrangements will be made with brokerage houses and other custodians, nominees
and fiduciaries for proxy material to be sent to their principals, and Covanta
will reimburse such persons for their expenses in so doing. Covanta is also
retaining D.F. King & Co., Inc. to solicit proxies and will pay D.F. King &

Proxy Statement. Each proxy is revocable at any time prior to being voted by
delivering a subsequent proxy, by giving written notice to the Secretary of
Covanta or by attending this Annual Meeting and voting in person, provided

                                       3

examination and tabulation of the revocation or the subsequent proxy before the

(1) A Schedule 13D/A Report dated March 12, 2001 shows that 380,000 shares are
    held with sole voting power, 5,909,800 shares are held with shared voting
    power, 380,000 shares are held with sole dispositive power and 5,909,800
    shares are held with shared dispositive power.

(2) A Schedule 13G Report dated February 15, 2001 shows that 3,009,900 shares
    are held with shared voting power and 3,009,900 shares are held with shared
    dispositive power.

(3) A Schedule 13G/A Report dated February 14, 2001 shows that 499,900 shares
    are held with sole power to vote or to direct the vote and 2,896,030 shares
    are held with sole power to dispose or direct the disposition thereof.

(4) A Schedule 13G Report dated February 2, 2001 shows that 2,502,789 shares are
    held with sole power to vote or to direct the vote and sole power to dispose
    or direct the disposition thereof.

    The proxy card provides space for a shareholder to withhold voting for any
or all nominees for the Board of Directors, or to abstain from voting for any
proposal if the shareholder chooses to do so. Each nominee for election as a
director requires a plurality of the votes cast in order to be elected.
Proposals (2) and (3) require the affirmative vote of the holders of a majority
of the votes represented by shares present at the Annual Meeting, in person or
by proxy and entitled to vote. With respect to the election of directors, only
shares that are voted in favor of a particular nominee will be counted towards
achievement of a plurality; where a shareholder properly withholds authority to
vote for a particular nominee such shares will not be counted towards such
nominee's or any other nominee's achievement of plurality. With respect to the
other Proposals to be acted upon: (i) if a shareholder abstains from voting on
the proposal, such shares are considered present at the meeting for quorum
purposes but, since they are not affirmative votes for the proposal, they will
have the same effect as votes against the proposal and (ii) under Delaware law,
shares registered in the names of brokers or other "street name" nominees for
which proxies are voted on some but not all matters will be considered to be
voted only as to those matters actually voted, and will not have the effect of
either an affirmative or negative vote as to the matters with respect to which
the broker does not have authority to vote and a beneficial holder has not
provided voting instructions (commonly referred to as "broker non-votes").

COMMITTEES OF THE BOARD OF DIRECTORS

    COMPENSATION COMMITTEE.  The Compensation Committee is composed of four
independent "non-employee directors" within the meaning of Rule 16b-3
promulgated under Section 16(b) of the Securities Exchange Act of 1934, as
amended, and "outside directors" within the meaning of Section 162(m) of the
Internal Revenue Code of 1986, as amended, who are not employees or members of
management of Covanta or any of its subsidiaries. The Compensation Committee is
responsible for reviewing and approving compensation and benefit plans for
Covanta and providing independent judgment as to the fairness of the
compensation and benefit arrangements for senior management of Covanta and its
subsidiaries. The Compensation Committee determines the method of payment to be
used for performance-based compensation; recommends the amount and form of
remuneration for

                                       5

non-employee members of the Board of Directors; determines the Chief Executive
Officer's compensation; and reviews and approves the annual salary, bonus and
other benefits, direct or indirect, of other designated members of senior
management of Covanta and its subsidiaries. There were eight meetings of the
Compensation Committee during 2000.

    AUDIT COMMITTEE.  The Audit Committee is composed of four independent and
financially literate non-employee outside directors as those terms are used in
the New York Stock Exchange rules, one or more members of which has accounting
or financial management expertise. The Audit Committee's principal functions are
to evaluate and review financial procedures, controls and reporting; compliance
with Covanta's Corporate Policy of Business Conduct; recommend to the board
external auditors; approve the budgeted fees for external audit services;
nominate to the Chairman of the Board Covanta's Chief Accounting Officer; and
consult with the Chief Executive Officer, Chief Financial Officer, Chief
Accounting Officer and the internal auditor as to any significant risks or
obligations. The Committee also assesses measures taken by management to manage
these risks; assesses the manner and extent of the audit to be carried out by
Covanta's internal and external auditors; reviews the adequacy of internal
controls; discusses the results of the annual audit with the external auditors;
reviews annually the business expenses of the members of the Board of Directors
and the Chief Executive Officer; and reviews with management all interim and
audited financial statements contained in reports filed with the Securities and
Exchange Commission. There were six meetings of the Audit Committee during 2000.

    GOVERNANCE COMMITTEE.  The Governance Committee is composed of five
independent non-employee outside directors. The Governance Committee's principal
functions are to review and evaluate Covanta's Board practices. In particular,
the Committee will be responsible for monitoring and making recommendations on
issues such as Board size and composition, and CEO performance. The Committee
reviews, on an ongoing basis, the Board's performance as a whole as it relates
to recognized "best Board practices" in the area of corporate governance. The
Committee also makes recommendations to the Board of Directors with respect to
nominees for new directors (including nominations submitted in writing by
shareholders in compliance with the requirements of Covanta's By-laws) and board
committee memberships with direct input from the Chairman of the Board of
Directors, Chief Executive Officer and the other directors. There were six
meetings of the Governance Committee during 2000.

    FINANCE COMMITTEE.  The Finance Committee is composed of five independent
non-employee outside directors. The principal responsibilities of the Finance
Committee are to review cash management policies, procedures and performance;
Covanta's banking relationships; and corporate transactions involving
investments, divestitures, loans, guarantees and expenditures involving
transactions exceeding $25 million. The Committee also reviews the annual
capital plan of investment results,

                                       6

strategic asset allocation, balance sheet structure and the management of equity
capital and risk management techniques. The Committee also submits a report of
its activities to the Board of Directors at least annually. There were four
meetings of the Finance Committee during 2000.

    During 2000 the Board of Directors held six regularly scheduled meetings and
four special meetings. Each incumbent director attended at least 75% of the
aggregate 2000 meetings of the Board of Directors and of the committees on which
such director served.

DIRECTOR COMPENSATION

    (a)  Directors Fees

    Each director who is not an employee of Covanta or a Covanta subsidiary
receives an annual director's retainer fee of $35,000 plus a meeting fee of
$1,500 for each Board of Directors meeting attended. Each non-employee director
will also receive a meeting fee of $1,500 for each committee meeting attended.
All directors are reimbursed for expenses incurred in attending Board of
Directors and committee meetings. Directors who are employees of Covanta or a
Covanta subsidiary receive no additional compensation for serving on the Board
of Directors or any committee.

    (b)  Stock Options

    Pursuant to the Covanta Amended and Restated 1999 Stock Incentive Plan (the
"1999 Plan"), the Board of Directors may award annual grants of Directors Stock
Options and limited stock appreciation rights of up to 2,500 shares of Covanta
Common Stock to each non-employee director, at an exercise price equal to the
Fair Market Value on the date of grant. On January 20, 2000, each non-employee
director was granted an option for 2,500 shares at an exercise price of $12.9688
per share, the Fair Market Value of a share of Covanta Common Stock on the date
of grant. Each option is a ten year grant vesting at the rate of 33.3% each year
over a period of three years.

    (c)  Restricted Stock

    On February 17, 2000 the Board of Directors adopted the Covanta Restricted
Stock Plan for Non-Employee Directors (the "Director's Restricted Stock Plan")
which is administered by the Board of Directors and provides that only
non-employee directors are eligible to receive awards. Each award of restricted
stock will vest upon the earliest of the third month following the date of
grant; the non-employee director's attainment of age 72; the non-employee
director's disability; or the non-employee director's death. Shares are freely
transferable after they become vested subject to meeting certain SEC
requirements. All unvested shares of restricted stock are forfeited upon the

                                       7

director's termination of directorship for any reason, other than death or
disability. Shares become fully vested upon a change-in-control of the company.
Shares of Common Stock to be issued under the Director's Restricted Stock Plan
will be made from shares held in Covanta's treasury, the maximum aggregate
number of shares authorized to be issued is 100,000 shares and the purchase
price for each share issued is zero.

    Under the Director's Restricted Stock Plan, each non-employee director will
automatically be paid in the form of restricted stock as follows: (i) 50% of the
director's annual retainer fees as of the first Board Meeting of each fiscal
year based on the closing price of a share of Common Stock on the date of such
meeting and (ii) 50% of the director's meeting fees as of the last day of each
calendar quarter in which such meeting occurs based on the average closing price
of a share of Common Stock for the calendar quarter. In the event of a
change-in-control of Covanta, shares of restricted stock which would otherwise
be made on the last day of the calendar quarter in which the change-in-control
occurs, will be made on the date of the change-in-control.

    In recognition of the special role that Mr. Farr is performing as Covanta's
Chairman of the Board, the Board of Directors authorized a special compensation
package for Mr. Farr that will apply only during the period of time in which he
is serving in this special role. The compensation package provides for a monthly
retainer of $35,000, payable 50% in cash and 50% in restricted stock at the end
of each quarter, commencing during the first quarter of 2000 and subject to
review by the Compensation Committee on a quarterly basis. During this period of
time Mr. Farr will not be paid any director or committee retainer or meeting
fees.

ELECTION OF DIRECTORS--PROPOSAL NUMBER (1)

PROPOSED ACTION

    The Covanta Board of Directors is proposing the election of four directors.
The directors will be elected for terms expiring at the Annual Meeting of
Shareholders in 2004 and until their respective successors have been elected and
qualified.

DESCRIPTION OF PROPOSAL

    The Board of Directors has nominated the four persons named in the table
below for election as the class of Directors whose terms expire at the 2004
Annual Meeting of Shareholders and until their respective successors are elected
and qualified. Covanta has no reason to believe that any such nominee will be
unable to serve as a director if elected, but if any nominee should subsequently
become unavailable to serve as a director, the persons named as proxies, or
their respective substitutes, may, in their discretion, vote for a substitute
nominee designated by the Board of Directors or, alternatively, the Board of
Directors may reduce the number of directors to be elected at this Annual
Meeting.

    Messrs. Smith and Bolland were elected directors at Covanta's 1990 and 1998
Annual Meeting of Shareholders, respectively. Mr. Mackin was appointed a
director and President and Chief Executive Officer of Covanta in
September 1999. Prior thereto, Mr. Mackin served as an Executive Vice President
of Covanta and since 1991 he has served as President and Chief Operating Officer
of Covanta Energy

                                       10

Group, Inc., a major subsidiary of Covanta. Mr. Matthews has been nominated to
replace Judith D. Moyers, who will be retiring from the Board following the 2001
Annual Meeting.

    Mr. Matthews graduated from Rutgers University in 1965 with a Bachelor's
Degree in Civil Engineering and in 1971 obtained his M.S. Degree in Industrial
Management/Finance from Polytechnic University. Since 1965, Mr. Matthews has
held various management positions in the corporate planning, financial,
marketing and engineering areas of Brooklyn Union Corporation. Since 1991, he
has served as Executive Vice President with responsibility for Brooklyn Union's
financial, gas supply, energy-related investments and information systems and
strategic planning functions. On May 28, 1998, Brooklyn Union's parent company
merged with Long Island Lighting Company, forming a company called KeySpan
Corporation. On January 28, 1999, Mr. Matthews was promoted to President and
Chief Operating Officer of KeySpan and President and Chief Operating Officer of
its major subsidiary, KeySpan Energy Delivery, formerly the Brooklyn Union
Corporation. On March 1, 2001, Mr. Matthews was named KeySpan's Vice Chairman
and appointed to its Board of Directors. Mr. Matthews is a member of the Board
of Directors of the American Gas Association and Chairman of the Board's
Research Committee. He is also a director of the Houston Exploration Company and
KeySpan Corporation.

RECOMMENDATION

    THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS VOTE FOR THE
ELECTION OF ALL FOUR NOMINEES NAMED ABOVE AS DIRECTORS--PROPOSAL NUMBER (1)

RATIFICATION OF AUDITORS--PROPOSAL NUMBER (2)

PROPOSED ACTION

    Shareholders are requested to ratify the continued appointment of
Deloitte & Touche LLP as auditors of Covanta and its subsidiaries for the year
2001. A representative of Deloitte & Touche LLP is expected to be present at
this Annual Meeting with the opportunity to make a statement if he or she
desires to do so and to respond to appropriate questions.

DESCRIPTION OF PROPOSAL

    Deloitte & Touche LLP has been Covanta's auditors since 1951. Audit and
other services rendered by Deloitte & Touche LLP for the fiscal year ended
December 31, 2000, in addition to the audit of the consolidated financial
statements, included: review of financial and related information that is to be
included in filings with the Securities and Exchange Commission; consultation
during the year on matters related to accounting and financial reporting; audits
of financial statements of certain subsidiary companies; audits of employee
benefit plans contained in filings required pursuant to the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"); consulting services; and
meeting with Covanta's Audit Committee on matters related to the audit. Although
Covanta is not required to submit the selection of auditors to the shareholders
for ratification, it has elected to do so. In the event such selection is not
ratified, Covanta would consider the selection of other auditors for fiscal
years after 2001. However, it would not be possible to replace Deloitte & Touche
LLP as auditors for the 2001 fiscal year without significant disruption of
Covanta's business.

VOTE REQUIRED

    The affirmative vote of the holders of a majority of the votes present at
this Annual Meeting in person or by proxy and entitled to vote will be required
to approve the continued appointment of Deloitte & Touche LLP as auditors of
Covanta and its subsidiaries for the year 2001.

RECOMMENDATION

    THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS VOTE FOR PROPOSAL
NUMBER (2)

                                       14

SHAREHOLDER PROPOSAL--PROPOSAL NUMBER (3)

    Amalgamated Bank Long View MidCap 400 Index Fund ("Amalgamated") has been
the beneficial owner of shares of the Company's Common Stock with a market value
of at least $2,000, has held such shares continuously for at least one year and
has advised it intends to maintain such ownership through the date of the 2001
Annual Shareholders Meeting. Amalgamated has submitted the following resolution
and supporting statement for inclusion in this Proxy Statement and will cause
the resolution to be introduced at the Annual Shareholders Meeting:

    RESOLVED: The shareholders of Ogden Corporation ("Ogden" or the "Company")
urge the Board of Directors to obtain prior shareholder approval for all future
agreements that provide compensation for senior executives if there is a change
in control of the Company.

                              SUPPORTING STATEMENT

    Ogden Corporation has entered into employment agreements with its Chief
Executive Officer and several other senior officers, which agreements provide
these officers with special severance compensation in certain situations where
there is a change in control of the Company.

    These severance agreements, commonly known as "golden parachutes," provide
that if the covered officers resign or are terminated under circumstances
covered by the employment agreement, the CEO shall be entitled to receive a cash
payment equal to the product of five times his base salary at the highest annual
rate in effect at any time prior to the termination date, and the highest amount
of annual bonus payable at any time prior to the termination date and, if
applicable, an additional payment equal to the amount of any excise tax imposed
on any payments under the agreement (including the additional payment) under the
excess parachute payments of the Internal Revenue Code. Other senior officials
are entitled to receive multiples of their base salary and annual bonus.

    These agreements could generate individual severance packages exceeding
$5 million apiece if the golden parachutes are ever exercised.

    Ogden's golden parachute agreements were adopted without the prior approval
of shareholders, and we believe that shareholders should be able to vote on such
agreements in the future, as a means of assessing potential conflicts of
interest between executives and shareholders.

    In our view, golden parachutes have the potential to create the wrong
incentives, reduce shareholder value and reward mismanagement. Change in control
concerns are more likely to occur if executives have managed the company in ways
that do not maximize shareholder value, and the

                                       15

existence of golden parachutes can allow covered executives to walk away with
millions of dollars even if shareholder value has suffered during their tenure.

    Shareholder value at Ogden has suffered in recent years. Although the last
year has seen a modest improvement, the fact remains that as of
mid-January 2001, Ogden's stock is still trading below levels seen five years
ago. During the same five year period, the stock has underperformed the S&P 500
and the MidCap 400 indices.

    We believe that shareholders should have the opportunity to review Ogden
parachute arrangements in the future.

    We Urge You To Vote FOR This Resolution

BOARD OF DIRECTORS' REASONS FOR OPPOSING THE PROPOSAL

    The Board of Directors believes that agreements which provide compensation
to employees in the event of an acquisition of the Company (formerly known as
Ogden) are consistent with sound corporate governance and serve the best
interest of the shareholders. These agreements provide an incentive for
employees to remain with the Company in the face of real uncertainty about their
future careers and employment prospects that arises in connection with a
potential acquisition. Without these agreements, there would be a significant
risk that key employees would resign from the Company during negotiations for
the sale of the Company, which would potentially harm the shareholders by
reducing the price at which the Company could be sold or leaving the Company
without important management resources if the sale did not occur.

    The Board of Directors further believes that change-of-control employment
agreements can be necessary to attract and retain top management talent. While
the Board of Directors does not currently expect that the Company will enter
into additional change-of-control employment agreements, this may change as
future circumstances dictate. In the event of any such change, the Board of
Directors expects to limit the amount of severance benefits in any such
employment agreement to not more than three years compensation. Requiring
shareholder approval of change-in-control agreements would hamper the Board's
flexibility to act promptly, decisively and with a competitive edge in
attracting and retaining top level management. Since very few of the Company's
competitors in the labor market require such approval and since these types of
agreements are very common, the Company would be at a distinct disadvantage in
management hiring.

    For the reasons set forth above, the Board of Directors urges shareholders
to reject this proposal.

                                       16

VOTE REQUIRED

    The affirmative vote of the holders of a majority of the votes present at
this Annual Meeting in person or by proxy and entitled to vote will be required
to approve Proposal Number (3).

RECOMMENDATION

    THE BOARD OF DIRECTORS RECOMMENDS A VOTE AGAINST THE ADOPTION OF THE
FOREGOING SHAREHOLDER PROPOSAL NUMBER (3). PROXIES SOLICITED BY THE BOARD OF
DIRECTORS WILL BE SO VOTED UNLESS SHAREHOLDERS OTHERWISE SPECIFY IN THEIR
PROXIES.

                         COMPENSATION COMMITTEE REPORT
                           ON EXECUTIVE COMPENSATION

THE EXECUTIVE COMPENSATION PROGRAM

PHILOSOPHY

    The Company's Compensation Committee (the "Committee") of the Board of
Directors is responsible for developing the Company's executive compensation
philosophy. In addition, the Committee administers the compensation program with
respect to the Company's Chief Executive Officer ("CEO") and other senior
executive officers.

    The primary goal of the Company's compensation philosophy is to establish
incentives that encourage and reward the creation of shareholder value. This
"pay-for-performance" principle permeates all elements of the Company's
compensation program, which is designed to align executives' financial interests
with those of our shareholders. The mix of direct compensation is being shifted
toward a greater emphasis on long-term performance. The Company seeks to reward
exceptional performers--those individuals whose job performance clearly exceeds
expectations and is consistent with the Company's financial goals and corporate
values.

    The Committee retains outside compensation consultants to assist in
implementing the compensation philosophy and in periodically comparing the
Company's compensation levels with other similarly sized companies in the
markets in which it operates. These companies are included in the Standard &
Poors indices shown in the performance graphs.

    To attract and retain high caliber executives, the Company targets its
executives' total compensation opportunity for superior performance at
approximately the 75th percentile of the competitive market. Actual compensation
levels may vary, depending upon individual performance, achievement of business
unit goals, the Company's results of operations and actual shareholder returns
realized. The primary elements of the Company's current compensation
arrangements are discussed below.

BASE SALARY

    The Company targets base salary levels to attract, motivate and retain
talented executives who demonstrate the personal and professional qualities
required to succeed in the Company's entrepreneurial culture and who meet or
exceed our goals and standards for exceptional performance. As the Company
continues to increase its emphasis on long-term incentive compensation, it is
expected that while base salary will remain competitive, it will comprise a
smaller proportion of the total compensation received by our executive officers.

                                       18

ANNUAL INCENTIVE

    The Company's annual incentive bonus payments are designed to be highly
variable based on the achievement of relevant quantitative and qualitative
criteria established by the Committee, which may vary from year to year.
Historically, annual incentive awards have been based upon any or all of the
following elements: earnings-per-share, cash flow, business unit operating
income and attainment of team and individual goals. For 2000, based on the
changes in the nature of the Company's business, the Committee gave particular
consideration to the growth in the Company's energy earnings before interest and
taxes resulting from continuing operations (excluding the results of Ogden
Environmental and Energy Services, corporate overhead and interest on corporate
level debt) ("Energy EBIT") and extraordinary individual efforts in connection
with the sale of non-core businesses and the financial restructuring of the
Company. The Committee believes that annual incentive bonuses reinforce the
Company's pay-for-performance philosophy and it intends to continue rewarding
individuals whose performance contributes to the Company's achievement of its
strategic and financial objectives. To emphasize our commitment to linking
management incentives with shareholder value, a portion of annual incentive
awards attributable to 2000 performance were paid in the form of the Company's
restricted stock.

LONG-TERM INCENTIVES

    The Committee believes that creation of shareholder value is best
facilitated through clear and uncomplicated long-term incentives. Accordingly,
the Company grants stock options on an annual basis to encourage equity
ownership and better align executives' and shareholders' interests. These grants
currently vest over a three-year period and are concentrated among those
executives who the Company believes have the greatest potential to substantially
increase shareholder value. The size of these annual grants reflects a variety
of factors, including corporate performance during the most recent fiscal year,
overall compensation levels for comparable positions in the competitive market,
consideration of a given individual's importance in implementing the Company's
long-term strategic plan and an evaluation of individual performance and
previous option grants.

CHIEF EXECUTIVE OFFICER (CEO) COMPENSATION

    In assessing competitors' compensation levels and practices, the Committee
reviews data covering the industries within which the Company competes as well
as general industry data. Consistent with the Company's pay-for-performance
compensation philosophy and the desire to align Mr. Mackin's incentives with
those of the Company's shareholders, Mr. Mackin's base salary for 2000 was set
at $600,000 per annum and his target annual incentive bonus was set at 100% of
his base salary. Mr. Mackin did not receive an option grant in 2000 since he
received a front-loaded grant of 450,000 stock options in 1999.

                                       19

    The Executive Performance Incentive Plan ("EIP") adopted by the Committee
and the Board and approved by shareholders in 2000 sets forth a target bonus
payment that can be earned by Mr. Mackin based upon achievement of one or more
business criteria as designated by the Committee. For 2000, the Committee
designated that the maximum funding for the CEO award be equal to 2% of positive
Energy EBIT. The bonus actually earned by Mr. Mackin under the EIP was $650,000
in cash and $89,700 in the form of restricted stock.

    It is anticipated that only Covanta's Chief Executive Officer will be
eligible to receive awards under the Executive Performance Incentive Plan for
the 2001 fiscal year. For 2001, the maximum bonus award that may be paid to
Mr. Mackin upon Covanta's achievement of the performance goals established by
the Committee shall once again be equal to 2% of Energy EBIT. The bonus actually
earned by Mr. Mackin will be based upon the achievement of other business
objectives at the sole discretion of the Committee.

POLICY REGARDING DEDUCTIBILITY OF EXECUTIVE COMPENSATION

    The Company's policy regarding deductibility of executive pay in excess of
$1 million is to preserve the tax deductibility of such amounts by having annual
incentive bonuses for executives and stock options qualified as
performance-based compensation under the IRS rules. The EIP and the Company's
1999 Stock Incentive Plan, both of which were adopted by the Committee and the
Board, and approved by shareholders, constitute the largest elements of the
Company's senior executives' compensation packages. The Committee acknowledges
that there may be certain non-cash "imputed income" items and certain
non-incentive designed plans which may cause pay to exceed $1 million in any
year. This policy does not contemplate restricting the Committee from using
discretionary business judgment as it determines appropriate.

COVANTA ENERGY GROUP PENSION PLAN

    Scott G. Mackin, Jeffrey R. Horowitz, Paul B. Clements and Bruce W. Stone
participate in the Company's Energy Group Pension Plan, a tax-qualified defined
benefit plan subject to the provisions of the Employee Retirement Income
Security Act of 1974, as amended. Under the Energy Group Pension Plan each
participant who meets the plan's vesting requirements will be provided with an
annual benefit at or after age 65 equal to 1.5% of the participant's average
compensation during the five consecutive calendar years of employment out of the
ten consecutive calendar years immediately preceding his retirement date or
termination date during which such average is the highest, multiplied by his
total years of service. Compensation includes salary and other compensation
received during the year and deferred income earned, but does not include
imputed income, severance pay, special discretionary cash payments or other
non-cash compensation. The relationship of the covered compensation to the
annual compensation shown in the Summary Compensation Table would be the Salary
and Bonus columns and any car allowance. A plan participant who is at least age
55 and who retires after completion of at least five years of employment
receives a benefit equal to the amount he would have received if he had retired
at age 65, reduced by an amount equal to 0.5% of the benefit multiplied by the
number of months between the date the participant commences receiving benefits
and the date he would have commenced to receive benefits if he had not retired
prior to age 65.

    Messrs. Mackin, Horowitz, Clements and Stone also participate in the
Company's Energy Group Supplemental Deferred Benefit Plan, a deferred
compensation plan which is not qualified for federal income tax purposes. The
Energy Group Supplemental Benefit Plan provides that, in the event that the
annual retirement benefit of any participant in the Energy Group Pension Plan,
determined pursuant to such plan's benefit formula, cannot be paid because of
certain limits on annual benefits and contributions imposed by the Code, the
amount by which such benefit must be reduced will be paid to the participant
from the general assets of the Company.

                                       24

    The following table shows the estimated annual retirement benefits payable
in the form of a life annuity at age 65 under the Energy Group Pension Plan and
the Energy Group Supplemental Benefit Plan. Mr. Mackin has 14.5 years,
Mr. Stone has 24.8 years, Mr. Horowitz has 9.5 years and Mr. Clements has
7.1 years of credited service under the Energy Group Pension Plan as of
December 31, 2000 and had annual average earnings for the last five years of
$982,455, $489,544, $321,720 and $323,373 respectively.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

    Section 16(a) of the Securities Exchange Act of 1934 requires Covanta's
directors, officers and persons who beneficially own more than 10% of any class
of Covanta's equity securities to file certain reports concerning their
beneficial ownership and changes in their beneficial ownership of Covanta's
equity securities. Covanta believes that during fiscal 2000 all persons who are
required to file reports

                                       28

concerning their beneficial ownership as described above complied with their
Section 16(a) filing requirements.

                             AUDIT COMMITTEE REPORT

    Covanta's Audit Committee (the "Committee") operates under a formal, written
Audit Committee Charter which was approved and adopted by the Board of
Directors, a copy of which is attached to this Proxy Statement as Schedule A.

    Management is responsible for Covanta's internal controls and the financial
reporting process. Covanta's independent accountants are responsible for
performing an independent audit of Covanta's consolidated financial statements
in accordance with generally accepted auditing standards and to issue a report
thereon. The Committee's responsibility is to monitor and oversee these
processes.

    The Committee reviewed and discussed the audited financial statements of
Covanta for the fiscal year ended December 31, 2000 with Covanta's management
and management represented to the Committee that Covanta's financial statements
were prepared in accordance with Generally Accepted Accounting Principles. The
Committee discussed with Deloitte & Touche LLP, Covanta's independent auditors,
matters required to be discussed by Statement on Auditing Standards No. 61
(Communication with Audit Committees). The Committee also received the written
disclosures and the letter from Deloitte & Touche LLP required by Independence
Standards Board Standard No. 1 (Independence Discussion with Audit Committees),
and the Committee discussed with Deloitte & Touche LLP their independence from
Covanta and determined that the services provided by Deloitte & Touche LLP are
compatible with maintaining their independence.

    Based on the Committee's discussions with management and Deloitte & Touche
LLP and the committee's review of the representation of management and the
report of the independent accountants to the Committee, the Committee
recommended to the Board of Directors that Covanta's audited financial
statements be included in Covanta's Annual Report on Form 10-K for the fiscal
year ended December 31, 2000 for filing with the Securities and Exchange
Commission.

LEGAL PROCEEDINGS

(a) Shareholder Litigation

    As previously reported, certain complaints denominated as class actions (the
"Actions") were filed during 1999 in the United States District Court for the
Southern District of New York against the Company and certain of its former
executive officers. On April 28, 2000, all defendants filed a motion to dismiss
the Actions, with prejudice. On October 4, 2000, the Court issued a decision
granting the defendants' motion in full, and dismissing the Actions with
prejudice. A judgment to that effect was entered on October 9, 2000.

(b) Other Litigation

    As previously reported, during 1999, the Company received a summons and
complaint filed in the Supreme Court of the State of New York, brought by R.
Richard Ablon, the Company's former Chairman, President and Chief Executive
Officer. In December 1999, a settlement was reached wherein, among other terms,
Mr. Ablon agreed to withdraw his lawsuit by stipulation and without prejudice
pending the payment of certain amounts on or before July 3, 2000, whereupon the
withdrawal will automatically become a withdrawal with prejudice. All payments
have been made as required under the settlement by July 3, 2000 and the lawsuit
has been withdrawn with prejudice.

HOW TO RECEIVE YOUR ANNUAL REPORT AND PROXY STATEMENT ON-LINE

    Save Covanta Energy Corporation future postage and printing expense by
consenting to receive future annual reports and proxy statements on-line on the
Internet.

    Most shareholders can elect to view future proxy statements and annual
reports over the Internet instead of receiving paper copies in the mail. Those
shareholders will be given the opportunity to consent to future Internet
delivery when they vote their proxy. (For some shareholders, this option is only
available if you vote by Internet.)

    If you are not given an opportunity to consent to Internet delivery when you
vote your proxy, contact the bank, broker or other holder of record through
which you hold your shares and inquire about the availability of such an option
for you.

    If you consent, your account will be so noted and, when Covanta's 2001
Annual Report and the Proxy Statement for the 2002 Annual Meeting of
Shareholders become available, you will be notified on how to access them on the
Internet. Any prior consent you have given will remain in effect until
specifically revoked by you in the manner specified by the bank or broker that
manages your account.

    If you do elect to receive your Covanta materials via the Internet, you can
still request paper copies by contacting the Assistant Secretary at Covanta
Energy Corporation, Two Pennsylvania Plaza, New York, NY 10121.

                            AUDIT COMMITTEE CHARTER

    This Audit Committee Charter ("Charter") has been adopted pursuant to the
Covanta Corporation Board of Directors Policies on Corporate Governance adopted
by the Board of Directors (the "Board") of Covanta Energy Corporation (the
"Company"). The Audit Committee of the Board (the "Committee") shall review and
reassess this charter annually and recommend any proposed changes to the Board
for approval.

ROLE AND INDEPENDENCE: ORGANIZATION

    The Committee assists the Board in fulfilling its responsibility for
oversight of the quality and integrity of the accounting, auditing, internal
control and financial reporting practices of the Company. It may also have such
other duties as may from time to time be assigned to it by the Board. The
membership of the Committee shall consist of at least three directors, who are
each free of any relationship that, in the opinion of the Board, may interfere
with such member's individual exercise of independent judgment. Each Committee
member shall also meet the independence and financial literacy requirements for
serving on audit committees, and at least one member shall have accounting or
related financial management expertise, all as set forth in the applicable rules
of the New York Stock Exchange. The Committee shall maintain free and open
communication with the independent auditors, the internal auditors and Company
management. In discharging its oversight role, the Committee is empowered to
investigate any matter relating to the Company's accounting, auditing, internal
control or financial reporting practices brought to its attention, with full
access to all Company books, records, facilities and personnel. The Committee
may retain outside counsel, auditors or other advisors.

    One member of the Committee shall be appointed as chair. The chair shall be
responsible for leadership of the Committee, including scheduling and presiding
over meetings, preparing agendas, and making regular reports to the Board. The
chair will also maintain regular liaison with the Chairman of the Board, CEO,
CFO, the lead independent audit partner and the director of internal audit.

    The Committee shall meet at least four times a year, or more frequently as
the Committee or the Chairman of the Board considers necessary. At least once
each year the Committee shall have separate private meetings with the
independent auditors, management and the internal auditors. The Committee shall
have an opportunity to meet with the independent auditors in executive session
at each meeting.

                                       32

RESPONSIBILITIES

    Although the Committee may wish to consider other duties from time to time,
the general recurring activities of the Committee in carrying out its oversight
role are described below. The Committee shall be responsible for:

    - Recommending to the Board the independent auditors to be nominated for
      shareholder approval to audit the financial statements of the Company.
      Such auditors are ultimately accountable to the Board and the Committee,
      as representatives of the shareholders.

    - Evaluating, together with the Board and management, the performance of the
      independent auditors and, where appropriate, replacing such auditors.

    - Obtaining annually from the independent auditors a formal written
      statement describing all relationships between the auditors and the
      Company, consistent with Independence Standards Board Standard Number 1.
      The Committee shall actively engage in a dialogue with the independent
      auditors with respect to any relationships that may impact the objectivity
      and independence of the auditors and shall take, or recommend that the
      Board take, appropriate actions to oversee and satisfy itself as to the
      auditors' independence.

    - Reviewing the audited financial statements and discussing them with
      management and the independent auditors. These discussions shall include
      the matters required to be discussed under Statement of Auditing Standards
      No. 61 and consideration of the quality of the Company's accounting
      principles as applied in its financial reporting, including a review of
      particularly sensitive accounting estimates, reserves and accruals,
      judgmental areas, audit adjustments (whether or not recorded), and other
      such inquiries as the Committee or the independent auditors shall deem
      appropriate. Based on such review, the Committee shall make its
      recommendation to the Board as to the approval of the Company's audited
      financial statements.

    - Issuing annually a report to be included in the Company's proxy statement
      as required by the rules of the Securities and Exchange Commission.

    - Overseeing the relationship with the independent auditors, including
      discussing with the auditors the nature and rigor of the audit process,
      receiving and reviewing audit reports, and providing the auditors full
      access to the Committee (and the Board) to report on any and all
      appropriate matters.

    - Discussing with a representative of management and the independent
      auditors: (1) the interim financial information contained in the Company's
      Quarterly Report on Form 10-Q prior to its

                                       33

      filing, (2) the earnings announcement prior to its release (if
      practicable), and (3) the results of the review of such information by the
      independent auditors.

    - Overseeing internal audit activities, including discussing with management
      and the internal auditors the internal audit function's organization,
      objectivity, responsibilities, plans, results, budget and staffing.

    - Discussing with management, the internal auditors and the independent
      auditors the quality and adequacy of and compliance with the Company's
      internal controls.

    - Discussing with management and/or the Company's general counsel any legal
      matters (including the status of pending litigation) that may have a
      material impact on the Company's financial statements, and any material
      reports or inquiries from regulatory or governmental agencies.

    - Approving the budgeted compensation for external audit services as
      recommended by the CFO.

    - Nominating the Chief Accounting Officer to the Chairman of the Board.

    - Discussing with the independent auditors the audit plan, changes from the
      audit plan and any serious difficulties or differences in opinion with
      management encountered during the audit.

    - Discussing with the Chief Accounting Officer significant findings during
      the year and management's responses, any difficulties encountered in the
      course of audits, including any restrictions on the scope of work or
      access to required information and any changes to the plan for Internal
      Audit.

    - Reviewing in summary form the business expenses incurred by members of the
      Board of Directors and the CEO.

    - Submitting a report of the results of its activities to the Board of
      Directors at least annually.

    The Committee's job is one of oversight. Management is responsible for the
preparation of the Company's financial statements and the independent auditors
are responsible for auditing those financial statements. The Committee and the
Board recognize that management (including the internal audit staff) and the
independent auditors have more resources and time, and more detailed knowledge
and information regarding the Company's accounting, auditing, internal control
and financial reporting practices than the Committee does; accordingly the
Committee's oversight role does not provide any expert or special assurance as
to the financial statements and other financial information provided by the
Company to its shareholders and others.
