                  COVANTA ENERGY CLOSES MASTER CREDIT FACILITY


NEW YORK, MARCH 15, 2001 - Covanta Energy Corporation (NYSE: COV) today
announced that it has closed a master credit facility with its credit providers.
Bank of America, N.A. and Deutsche Bank AG, New York Branch, are the co-agents
of the facility.

As announced last week, the Company, formerly known as Ogden Corporation, has
changed its corporate name to Covanta Energy Corporation, effective yesterday.
The Company's new ticker symbol on the New York Stock Exchange is "COV".

"We are pleased to have reached agreement with our lenders on a master credit
facility. This facility is an important step forward and provides Covanta Energy
with the financial flexibility to complete our restructuring efforts, maintain
our current energy portfolio and continue to grow our energy business," said
Scott G. Mackin, President and Chief Executive Officer of Covanta Energy
Corporation. "Following the completion of our non-core asset sales process, we
expect to replace this facility with one structured to support Covanta Energy's
long-term growth plans as a pure play energy company."

The new facility, which matures May 31, 2002, is secured and includes a
revolving credit facility of approximately $146 million and coordinates the
administration of the Company's existing credit facilities. This master facility
provides for continued investment in existing and new energy projects, which
could approximate up to $100 million in 2001. These investments include
continued funding for projects under construction, the Three Mountain Power
Project currently being permitted in California, other plant-related
expenditures and funding for additional projects currently under evaluation.
Covanta Energy's ability to make investments in new energy projects is subject
to certain conditions, including meeting minimum cashflow requirements, which
includes the sale of non-core assets. Under the terms of the agreement, Covanta
Energy repaid approximately $146 million of outstanding indebtedness, which is
the amount that has been on its balance sheet under the heading "Restricted
Cash-Intended to Repay Debt" on the closing date of the master facility.

The Company does not expect the completion of the facility to affect its
previously announced projection of $115 million in recurring base earnings
before interest and taxes (EBIT) for 2001.

Certain statements included in this news release are forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934. Forward-looking statements above
include, but are not limited to, expected earnings and future financial
performance. Although Covanta Energy believes that its expectations are
reasonable, it can give no assurance that these expectations will prove to have
been correct. Factors that could cause Covanta Energy's actual results to differ
materially from those contemplated in the forward-looking statements above
include, among others, the following:
   -- Economic, capital market and other business conditions effecting power
generation enterprises specifically and commerce generally including interest,
inflation and exchange rates; weather conditions; creditworthiness of customers
and suppliers, changes in fuel costs and supply; unscheduled outages;
environmental incidents; electric transmission restraints; and risks and
uncertainties associated with the recently deregulated energy industry;
   -- Trade, monetary, fiscal, taxation, energy regulation and environmental
policies of governments, agencies and similar organizations in geographic areas
where Covanta Energy has a financial interest;
   -- Financial or regulatory accounting principles or policies imposed by the
Financial Accounting Standards Board, the Securities and Exchange Commission,
the Federal Energy Regulatory Commission and similar entities with regulatory
oversight, including without limitation the impact of newly adopted FASB 133
relating to accounting for derivatives which will be effective beginning January
1, 2001. The impact of FASB 133 will vary between accounting periods based on
changes in pricing of various items bought and sold by the Company.
   -- Cost and other effects of legal and administrative proceedings,
settlements, investigations and claims;
   -- Limitations on Covanta Energy's ability to control the development or
operation of projects in which Covanta Energy has less than 100% interest;
   -- The lack of operating history at development projects provides only a
limited basis for management to project the results of future operations;
   -- Risks associated with timely completion of development projects, including
obtaining competitive contracts, obtaining regulatory and permitting approvals,
local opposition, and construction delays;
   -- Factors associated with operating in foreign countries, including
political instability and risk of war, expropriation and nationalization,
renegotiation or nullification of existing contracts; changes in law; and the
ability to convert foreign currency into United States dollars;
   -- Factors which would affect the performance of the Company's remaining
assets and liabilities relating to the aviation and entertainment businesses,
including the demand for its fueling services, utilization of the Corel and
Anaheim arenas and indemnity and other claims relating to disposed of
operations.
   -- Other business or investment considerations that may be disclosed from
time to time in Covanta Energy's Securities and Exchange Commission filings or
in other publicly disseminated written documents.

Covanta Energy undertakes no obligation to update or revise any forward-looking
statements, whether as a result of new information, future events or otherwise.
The foregoing review of factors that could cause Covanta Energy's actual results
to differ materially from those contemplated in the forward-looking statements
included in this news release should not be construed as exhaustive. For more
information regarding these risks and uncertainties, review Covanta Energy's
filings with the Securities and Exchange Commission.
