RATING ACTION: COVANTA ENERGY CORPORATION

MOODY'S ASSIGNS Caa1 RATING TO COVANTA ENERGY CORPORATION'S 8.25% SENIOR NOTES
AND SGL-3 SPECULATIVE LIQUIDITY RATING; OUTLOOK STABLE


         APPROXIMATELY $230 MILLION OF DEBT SECURITIES AFFECTED.

         New York, May 28, 2004 -- Moody's Investors Service has assigned a Caa1
         rating to Covanta Energy Corporation's (Covanta) 8.25% Senior Secured
         Notes due 2011. The Notes were issued to the holders of Covanta's
         secured claims upon the company's emergence from bankruptcy on March
         10, 2004. Moody's assigned a senior implied rating of B3. Moody's also
         assigned a Caa1 Issuer Rating and an SGL-3 speculative liquidity rating
         to Covanta. The outlook of the Covanta ratings is stable.

         The Caa1 Notes rating and Issuer Rating reflect the following factors:

         Covanta exhibits limited financial flexibility and relatively low
         interest coverage ratios assuming it is able to fully utilize new
         parent Danielson Holding Company's (Danielson) net operating loss carry
         forwards (NOLs). Projected interest coverage on the Notes over the next
         several years ranges from a low of .97x in 2005 to a high of 1.4x in
         2007. Without the NOLs, coverage levels would be lower. In addition,
         the Notes are structurally subordinated to approximately $840 million
         of debt at the subsidiary waste-to-energy projects and $256 million of
         bank letter of credit facilities at Covanta. This is somewhat mitigated
         by the fact that the letter of credit facilities are performance
         letters of credit and Covanta has never experienced a draw under a
         performance letter of credit. The source of repayment for the Notes
         includes the cash flow generated from the Covanta projects in addition
         to any available assets at Covanta itself, which are currently minimal.
         Covanta is currently highly leveraged following its emergence from
         bankruptcy, with total recourse debt and commitments of $486 million
         compared to only $44 million of book equity, most of which was provided
         by Danielson. Danielson is primarily a financial investment vehicle
         with no experience in waste-to-energy, independent power production, or
         water/wastewater.

         There is uncertainty related to the availability of $571 million of
         NOLs from Danielson, which are necessary to offset taxable income at
         Covanta. These NOLs could be substantially reduced should there be an
         "ownership change" at Danielson. Without the application of these NOLs,
         Covanta does not generate sufficient cash flow to meet interest
         obligations on the Notes and fees under its bank letter of credit
         facilities. Covanta's auditors prior to its acquisition by Danielson,
         Deloitte & Touche, in their 2003 independent auditors report issued
         subsequent to the company's emergence from bankruptcy, expressed
         substantial doubt about Covanta's ability to continue as a "going
         concern". Reasons cited include Covanta's ability to utilize
         Danielson's NOLs and its ability to generate sufficient cash flows from
         operation, asset sales, and financing arrangements to meet its
         obligations.

         The B3 senior implied rating reflects the following additional factors:

         The underlying waste-to-energy projects generate relatively stable cash
         flows and Covanta management has exhibited a strong track record of
         positive operating performance, with availability factors consistently
         at 90% or above over the past several years. Although some of the
         underlying waste-to-energy projects are located in the attractive
         Northeast region of the country, which is characterized by dense
         population and limited waste disposal alternatives, others are located
         in regions where landfill and other waste alternatives are more
         available and competitive with waste-to-energy.



         Covanta derives approximately two-thirds of its revenues from its
         waste-to-energy business, for the most part from long-term contracts
         with a diverse group of municipalities, with the remaining one-third of
         revenues derived from independent power sales, most of which are under
         long-term contracts. Although the overall business is highly
         contracted, the risk exists that contracts could be modified or
         abrogated. In addition, Covanta faces the ongoing challenge of changes
         in environmental laws or regulation, or the failure to comply with
         existing regulations, and the need to renew permits on an ongoing
         basis.

         Covanta's SGL-3 speculative grade liquidity rating reflects adequate
         liquidity for the next twelve months and the risks inherent in Covanta
         maintaining this liquidity including: limited financial flexibility and
         free cash flow, the dependence on parent company Danielson's NOLs to
         provide adequate coverage of long-term debt obligations, limited
         alternative liquidity sources including a relatively small $10 million
         revolving credit at Covanta's domestic businesses and a $10 million
         revolving credit at CPIH, its international subsidiary. There are few
         assets at the Covanta parent company level and most of the assets at
         the subsidiaries are pledged to $840 million of project level debt.
         Covanta also operates in a very specialized industry niche, with a
         limited market for assets to be sold off in a timely manner for
         liquidity purposes. Offsetting these factors is Covanta's relatively
         robust current cash position relative to their needs, which has
         increased from $44 million immediately following its exit from
         bankruptcy to approximately $48 million.

         The stable outlook on Covanta's rating reflects Moody's expectation
         that: (i) the waste-to-energy projects' contracts with the respective
         municipalities and utilities will remain in place through their current
         maturities; (ii) Covanta management will continue to operate the plants
         at high availability levels and maintain stability with regard to
         administrative expenses; (iii) Covanta will de-lever over the next
         several years at the subsidiary project level; and (iv) Covanta will be
         able to utilize all $571 million of Danielson's NOLs made available to
         it. However, the Covanta rating could be raised or lowered if dividends
         distributable from the projects differ from expected levels, if Covanta
         acquired additional waste-to-energy projects or was subject to
         unforeseen capital expenditure requirements at the existing projects,
         particularly with regard to environmental regulatory compliance, or if
         all or a part of Danielson's NOLs become unavailable to Covanta.

         Fourteen of Covanta's 23 waste-to-energy projects are rated by Moody's:
         Alexandria (A3), Babylon (Baa3), Bristol (A2), Detroit (Aa3), Fairfax
         (A1), Hillsborough (Aa2), Huntington (A3), Huntsville (A1), Lancaster
         (Baa2), Lee (Aa3), Mid-Conn (A1/Baa3), Montgomery (Aa3/A2), Union
         (Baa2/Baa3), and Wallingford (A2/A3). Two other waste-to-energy
         projects remain in bankruptcy. None of the smaller independent power or
         water facilities are rated except for the Quezon project in the
         Philippines, which is rated B3.

         Covanta Energy Corporation, headquartered in Fairfield, NJ, is an
         energy company with operations in waste-to-energy, independent power
         production, and water and wastewater. Parent company Danielson Holding
         Corporation, headquartered in Chicago, IL, has operations in insurance
         and marine services in addition to Covanta.
