                     DANIELSON HOLDING CORPORATION ACQUIRES
                           COVANTA ENERGY CORPORATION


CHICAGO, IL and FAIRFIELD, NJ - March 10, 2004- Danielson Holding Corporation
(AMEX:DHC) and Covanta Energy Corporation today announced that Danielson has
completed its previously announced acquisition of Covanta's energy and water
business allowing Covanta to emerge from bankruptcy. Covanta's plan of
reorganization was approved by the Bankruptcy Court for the Southern District of
New York pursuant to an order entered on March 5, 2004, allowing Covanta to
emerge from bankruptcy.

Covanta will remain headquartered in Fairfield, New Jersey. Anthony J. Orlando
will continue to serve as the company's Chief Executive Officer and the
company's existing management structure will stay in place.

"We are very pleased to have concluded Covanta's reorganization and are now
focused on the continued success of our waste-to-energy business," commented
Orlando. He added, "The plan approved by the court maximizes creditor recovery
and affords the company a solid capital structure. In addition, it enables us to
embark on a dynamic partnership with the Danielson team. By combining our
complementary skill sets, we will position Covanta to do what it does best -
provide our clients with world class, reliable service."

"The Covanta management team has performed an excellent job in meeting their
client community needs throughout this lengthy reorganization process," said Sam
Zell, Danielson's Chairman and Chief Executive Officer. "We look forward to
working with them to build on their solid foundation in the energy business."

Pursuant to a definitive investment and purchase agreement executed on December
2, 2003, Danielson has acquired 100% of Covanta's equity for approximately $30
million in cash. In addition, Danielson arranged a new $118 million letter of
credit facility for Covanta, secured by a second lien on Covanta's domestic
assets. With respect to Covanta's domestic operations, Covanta has obtained a
new $138 million first lien secured letter of credit facility and has issued
$205 million of senior secured notes accreting to $230 million by 2011, and up
to $50 million face amount of unsecured notes. As a result of these transactions
and the bankruptcy court's order, Covanta emerged from bankruptcy with over $50
million in cash and revolving credit facility availability. Covanta's
international operations also issued $95 million of secured 3-year term notes to
certain of Covanta's creditors.

As previously disclosed, Danielson did not purchase Covanta's geothermal assets,
which were sold in December, 2003 to Ormat Nevada, Inc., the winning bidder
following the auction of those assets.

The financing necessary for Danielson's acquisition of Covanta was provided by
three of Danielson's shareholders: SZ Investments, L.L.C. ("SZ Investments"),
Third Avenue Trust, on behalf of Third Avenue Value Fund ("Third Avenue"), and
D. E. Shaw Laminar Portfolios, L.L.C. ("Laminar"). In addition, Laminar has
arranged for the provision of a $10 million secured revolving loan facility to
Covanta's international operations. In connection with the financing by such
shareholders, Danielson issued notes that have an aggregate principal balance of
$40 million and, if not repaid, are convertible into shares of Danielson common
stock at a price of $1.53 per share. The proceeds from this financing remaining
after payment of the purchase price will be used to pay certain transaction
expenses and for general corporate purposes.

Danielson expects to refinance these convertible notes through a pro rata rights
offering to its shareholders. Under the terms of its agreement with SZ
Investments, Third Avenue and Laminar, Danielson is required to commence the
rights offering within 75 days of the closing of its acquisition of Covanta. As
previously announced, under this rights offering Danielson intends to issue
rights to purchase 0.75 shares of common stock for each outstanding share of
Danielson common stock at an exercise price of $1.53 per share. If Danielson
does not refinance all of the notes, the remaining principal balance and unpaid
interest of the notes would be convertible into shares of Danielson common stock
at the rights offering price of $1.53 per share. In addition, Laminar has agreed
to purchase up to an additional 8.75 million shares of Danielson common stock at
$1.53 per share based upon the levels of public participation in the rights
offering. The convertible note financing and other related party transactions
were approved by a special committee of independent directors of Danielson.

Danielson anticipates that it will issue rights to acquire approximately 27
million shares of its common stock. Assuming exercise of all rights and the
purchase of 8.75 million shares by Laminar, Danielson estimates that it will
have approximately 71 million shares outstanding following the rights offering.
In addition, following completion of the rights offering and sale of shares to
Laminar, Danielson has agreed to offer to sell up to 3 million shares of its
common stock to certain creditors of Covanta at a purchase price of $1.53 per
share.
