DANIELSON HOLDING CORPORATION
REPORTS 2005 SECOND QUARTER RESULTS
AND ANNOUNCES EARNINGS CALL

FAIRFIELD, NJ, August 9, 2005 – Danielson Holding Corporation (AMEX: DHC) today filed its Form 10-Q for the quarter ended June 30, 2005 with the Securities and Exchange Commission. Attached is the second quarter summary information:

• Business segment summary income statements

• Operating cash flow generated and available to service corporate debt of Covanta Energy Corporation (“Covanta”), Danielson’s subsidiary comprising its Waste and Energy Services segment

• Covanta Adjusted EBITDA for the twelve months ended June 30, 2005

For the quarter ended June 30, 2005, Danielson reported Consolidated Net Income of $5.9 million, or $0.05 per diluted share. Further, Total Covanta Operating Revenues were $195.3 million and Total Insurance Operating Revenues were $3.8 million for the second quarter of 2005. Danielson’s results include six days of results related to American Ref-Fuel which was acquired by Covanta on June 24, 2005.

“The highlight of this quarter was our completion of the American Ref-Fuel acquisition,” stated Anthony J. Orlando, President and Chief Executive Officer of Danielson. “In addition to completing the acquisition of American Ref-Fuel, I’m pleased that we were able to deliver another solid quarter of operating results in line with our expectations.” Orlando continued, “We continue to work diligently to assure that the ongoing transition and integration efforts remain on track. We are confident in our ability to deliver the synergies we previously announced and we look forward to taking advantage of opportunities presented by this strategic acquisition.”

Of the Total Covanta Operating Revenues Danielson reported for the second quarter of 2005, $158.9 million were attributable to Covanta’s domestic operations and $36.3 million were attributable to international operations. For the same period, Covanta’s operating income totaled $28.6 million, with domestic providing $25.8 million and international providing $2.8 million. For the second quarter of 2004, of the Total Covanta Operating Revenues Danielson reported, $145.9 million were attributable to Covanta’s domestic operations and $33.9 million were attributable to international operations. For the same period in 2004, Covanta operating income totaled $31.7 million, with domestic providing $26.7 million and international providing $5.0 million.

Non-GAAP Financial Measures

Attached are calculations of the following metrics, both of which are measurements not in accordance with generally accepted accounting principles: (i) cash flow generated and available for Covanta’s corporate long-term debt and letter of credit fees, which Danielson believes is a useful measure of the sufficiency of Covanta’s cash to pay its obligations under its new financing arrangements, after all other obligations are paid, and (ii) Covanta’s Adjusted EBITDA, the measurement of which relates to a material financial covenant in Covanta’s new financing arrangements and is presented to indicate Covanta’s ability to comply with this covenant.

For the quarter ended June 30, 2005, after-tax cash generated for Covanta’s corporate long-term debt and letter of credit fees was $31.7 million, of which $18.9 million was generated by domestic (including cash generated by American Ref-Fuel) and $12.8 million by international. Overall, the after-tax cash generated for Covanta’s corporate long-term debt and letter of credit fees was better than the prior year, largely due to cash generated by American Ref-Fuel. For the quarter ended June 30, 2004, after-tax cash generated for Covanta’s corporate long-term debt and letter of credit fees was $17.6 million, with domestic generating $7.7 million and international generating $9.9 million.

Covanta’s Adjusted EBITDA for the twelve months ended June 30, 2005 totals $235.7 million. Excluding the six days of American Ref-Fuel operations, Covanta’s adjusted EBITDA is slightly lower than the twelve months ended March 31, 2005. The decrease can be attributed largely to scheduled maintenance expenses that occurred in the second quarter offset by higher revenues during the period.

Non-GAAP Financial Measure — Operating Cash Flow Generated and Available for Covanta Debt and Letters of Credit Fees

The following summarizes unaudited non-GAAP financial measures for Covanta. Certain items are included in the table below that are not measured under GAAP and are not intended to supplant other information provided in accordance with GAAP. Furthermore, these measures may not be comparable to those used by other companies. The following information should be read in conjunction with the audited consolidated financial statements of Danielson Holding Corporation and the notes thereto as filed in its Annual Report on Form 10-K, as amended, for the year ended December 31, 2004, and the unaudited financial statements and notes thereto as filed in its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2005 and June 30, 2005.

Covanta must generate substantial cash flow from operations, upon which it depends as an important source of liquidity to pay project operating and capital expenditures, project debt, taxes, corporate operating expenses and debt and letters of credit fees. Management believes that a useful measure of the sufficiency of Covanta’s cash generated from operations is that amount available to pay debt service and letters of credit fees under its Senior Secured Credit Facilities, after all other obligations are paid.

The following table provides additional information with respect to cash available to pay Covanta’s debt and letters of credit fees under its Senior Secured Credit Facilities for the period April 1, 2005 through June 30, 2005.

Non-GAAP Financial Measure — Adjusted EBITDA for the Twelve Months Ended June 30, 2005

The following summarizes an unaudited non-GAAP financial measure for Covanta, which is used in calculating compliance with certain of Covanta’s financial covenants in its financing arrangements entered into on June 24, 2005. Certain items are included in the table below that are not measured under GAAP and are not intended to supplant other information provided in accordance with GAAP. Furthermore, these measures may not be comparable to those used by other companies. The following information should be read in conjunction with the audited consolidated financial statements of Danielson Holding Corporation and the notes thereto as filed in its Annual Report on Form 10-K, as amended, for the year ended December 31, 2004, and the unaudited financial statements and notes thereto as filed in its Quarterly Reports on Form 10-Q for the quarters ended March 31, 2005 and June 30, 2005. Adjusted EBITDA means, for any period, EBITDA plus additional items deducted from, or added to, net income, as defined in Covanta’s credit agreements. Adjusted EBITDA is not a measurement of financial performance under GAAP and should not be considered as an alternative to cash flow from operating activities or as a measure of liquidity or an alternative to net income as indicators of Covanta’s performance or any other measures of performance derived in accordance with GAAP. Adjusted EBITDA is a material covenant in Covanta’s credit agreement and is presented to show Covanta’s ability to comply with this covenant. Adjusted EBITDA for the period set forth below is reconciled to net income, which is believed to be the most directly comparable measure of GAAP.
