For the year ended December 31, 2000, the Company reported EBIT from its Energy
business of $79 million on revenues of $946 million, compared to EBIT of $62
million on revenues of $922 million in 1999. As previously announced, the
Company finalized the sale of its OEES consulting business to AMEC, effective
November 17, 2000, and is currently winding-down the two remaining projects in
its OEES construction operations. The 2000 EBIT includes $25 million of
non-recurring charges (net), consisting of $15 million of income principally
associated with the receipt of insurance proceeds, which was more than offset by
$18 million in losses at OEES and $22 million of one-time expenses. The one-time
expenses result primarily from actions taken as a result of an extensive study
by the Company, which examined overall energy operations and the methods of
doing business. As a result, Covanta has reorganized its operating structure,
redirected its development-spending program away from the Asian markets and has
reduced overhead costs across the organization. In concert with these decisions,
the Company announced the closure of its Hong Kong office.

The 1999 results include $18 million of non-recurring items, resulting primarily
from losses and impairment charges at its OEES subsidiary, partially offset by a
gain of $6 million from the sale of the Company's interest in an independent
power production (IPP) joint venture and a net one-time gain of approximately
$20 million principally related to the termination and restructuring of a
service agreement, as well as insurance proceeds from a waste-to-energy (WTE)
plant.

Adjusting for these items, the recurring base Energy EBIT for 2000 was $104
million, compared to $80 million for the comparable period in 1999. The increase
in recurring EBIT of $24 million, or 30%, is largely due to increased production
and favorable energy pricing, primarily at power plants in California, as well
as at other IPP and WTE sites. The increase in recurring EBIT is also
attributable to incremental income from the acquisition of the remaining
interest in the Heber plant in California during 1999, as well as the Company's
Quezon project in The Philippines, which came on stream in the second quarter of
2000. The Quezon project results are included in Energy equity income.

Revenues from continuing Energy operations for the year ended December 31, 2000
reflect an increase of $24 million over the comparable period in 1999. In
addition to the factors noted above, the increase in Energy revenues is also
favorably influenced by annual escalation adjustments at several facilities,
plus incremental revenues realized by the full-year operation in 2000 of plants
in Thailand and The Philippines, partially offset by the reduction in
construction revenues.

The Company's 2000 non-energy results include pre-tax charges of $77 million,
resulting from the write-down of assets held for sale at December 31, 2000 to
their expected net realizable value. The expected unrealized gains from the sale
of the remaining non-core assets will be recorded in the results from continuing
operations, as such sales occur throughout 2001.

FOURTH QUARTER RESULTS
For the fourth quarter 2000, the Company recorded recurring base EBIT of $29
million, compared to $21 million for the comparable period in 1999. Including
losses from discontinued operations and other special charges, the Company
reported a net loss of $89 million, or $1.79 per diluted share, for the fourth
quarter. The fourth quarter net loss is principally attributable to the asset
write-downs described above.

For the three months ended December 31, 2000, the Company reported EBIT from its
Energy business of $7 million, on revenues of $240 million, compared to a loss
before interest and taxes in the comparable period of 1999 of $11 million, on
revenues of $237 million. The fourth quarter 2000 EBIT reflects $22 million of
non-recurring charges, including $3 million in losses at OEES and charges of $19
million related to the actions taken as a result of the restructuring study
previously noted. The 1999 results include $32 million of non-recurring items,
resulting from $36 million of losses and impairment charges at OEES, and a net
one-time gain of approximately $4 million, principally related to insurance
proceeds from a WTE plant.

Adjusting for these items, the recurring base Energy EBIT for the three months
ended December 31, 2000, was $29 million, compared to $21 million for the
comparable period of 1999. The increase in recurring EBIT of $8 million, or 38%,
is primarily related to strong performance and enhanced pricing at a number of
IPP and WTE sites, including power plants located in California. In addition,
earnings before interest and taxes were favorably impacted by enhanced results
at several facilities in The Philippines (primarily at Quezon) and at the
Company's power plant at Haripur.

Revenues from continuing Energy operations for the three months ended December
31, 2000 increased $3 million over the comparable period of 1999. The increase
in Energy revenues is primarily due to increased production, higher energy rates
and annual escalation adjustments at several facilities, which contributed
approximately $23 million. This increase was offset, in part, by a $7 million
decrease in revenues following the disposition of the OEES consulting business,
a $5 million anticipated reduction in construction revenues and an $8 million
gain in 1999 related to insurance proceeds from a WTE facility.

MASTER CREDIT FACILITY
On March 14, 2001, the Company completed a master credit facility. The 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.

NON-CORE ASSET SALES
Covanta continues to make progress in its non-core asset sales process. Since
the end of the third quarter, as previously announced, the Company completed the
sale of its Fixed Base Operations business to the Latsis Group of Greece for
approximately $27 million, the sale of its Aviation Ground Services business to
John Menzies plc for approximately $105 million and the sale of the consulting
operations of OEES to AMEC for approximately $18 million. As of December 31,
2000, as a result of the non-core asset sales process, the Company had received
in excess of $440 million in cash proceeds and reduced related debt by
approximately $119 million. In addition, during February 2001, the Company
completed the sale of its interest in an Aviation ground handling operations
joint venture at Rome's Fiumicino Airport for approximately $10 million.
Numerous efforts are under way to conclude the sale of all non-core assets
during 2001.

OUTLOOK
Based on the performance of the Company's Energy business in 2000, Covanta
currently expects recurring earnings per share (EPS) for 2001 for its Energy
business of between $1.18 and $1.22. Embedded in this EPS projection is an
expectation that recurring base Energy EBIT will aggregate approximately $120 to
$123 million. The projected 17% growth in year-over-year EBIT is primarily due
to a full year's operation of the Quezon facility, partial year operation of two
new generating plants located in Asia, and one plant located in Europe and
reduced overhead throughout the Company's operations, partially offset by lower
construction revenues, reduced contribution from the Mammoth project, our
50%-owned geothermal facility in California, and increased depreciation and
operating costs as a result of Clean Air Act retrofits coming on-line.

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
