ITEM 1.01.        ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On December 15, 2004, Covanta Energy Corporation (the "Company"),
together with certain of its subsidiaries (the "Borrower Subsidiaries"), entered
into a First Amendment to Credit Agreement (the "First Lien Amendment") with
certain lenders, Bank of America, N.A., as Administrative Agent ("Bank of
America"), and Deutsche Bank Securities Inc., as Documentation Agent ("Deutsche
Bank"). The Amendment modified the terms of the Credit Agreement, dated as of
March 10, 2004, by and among the Company, the Borrower Subsidiaries, certain
lenders, Bank of America and Deutsche Bank (the "First Lien Credit Agreement").

         Also on December 15, 2004, the Company, together with the Borrower
Subsidiaries, entered into a First Amendment to Credit Agreement (the "Second
Lien Amendment") with certain lenders and Bank One, N.A., as Administrative
Agent ("Bank One"). The Amendment modified the terms of the Credit Agreement,
dated as of March 10, 2004, by and among the Company, the Borrower Subsidiaries,
certain lenders and Bank One (the "Second Lien Credit Agreement"). The First
Lien Amendment and the Second Lien Amendment are collectively referred to as the
"Amendments," and the First Lien Credit Agreement and the Second Lien Credit
Agreement are collectively referred to as the "Credit Agreements."

         The Amendments each modified the minimum consolidated net worth
covenant of the Company and its subsidiaries set forth in the respective Credit
Agreements. In addition, both Amendments revised the respective Credit
Agreements to permit the Company and its subsidiaries to terminate, sell and/or
assign obligations relating to certain landfill gas and wastewater projects, and
to restructure the organization of certain biomass facilities.

         A copy of the First Lien Amendment is attached hereto as Exhibit 10.1,
and a copy of the Second Lien Amendment is attached hereto as Exhibit 10.2. Both
are incorporated by reference herein.
