                                  AERCO LIMITED

                22 Grenville Street, St. Helier, Jersey, JE4 8PX
                                 Channel Islands

                                  PRESS RELEASE

Under the terms of the trust indenture dated as of July 15, 1998 as amended and
restated on July 17, 2000 (the "Trust Indenture") governing the AerCo Notes,
AerCo Limited ("AerCo" and, together with its subsidiaries "AerCo Group") is
required annually to commission an appraisal of the "base value" of the AerCo
Group portfolio from at least three independent appraisers.

AerCo has obtained desktop appraisals of the "base value" of each of AerCo
Group's 61 aircraft for the year to February 19, 2003 from three independent
aircraft value appraisers: Airclaims Limited ("Airclaims"), Aircraft Information
Services, Inc. ("AISI") and BK Associates, Inc. ("BK"). On the basis of these
three appraisals (Airclaims: $1,056.2 million; AISI $1,175.6 million; BK
$1,336.3 million), the average appraised base value of AerCo Group's portfolio
of aircraft as of February 19, 2003 was approximately $1,189.4 million (the
"2003 Appraised Value") compared with $1,301.9 million as of February 19, 2002.

The decline in the average appraised value of the portfolio at February 19, 2003
compared with the average appraised value at February 19, 2002 is approximately
$40 million greater than the decline in value assumed by the principal payment
tables included in the Trust Indenture. This greater decline is largely
attributable to the global economic downturn combined with the effects of the
terrorist attacks in the United States on September 11, 2001, and the
consequential negative effect that this has had on the global aviation industry
and in particular, on the values of all commercial aircraft.

As a result of the greater than expected decline in the appraised value of AerCo
Group's portfolio, AerCo is required to accelerate the scheduled principal
payments on the Class A Notes to the extent of available cash flows; thus, from
March 17, 2003 (the first payment date for which the 2003 appraisals will be
effective) AerCo will have to redirect certain cash flows, to the extent they
are available, towards eliminating an expected $14 million difference between
the Class A principal balance currently outstanding and the scheduled target
principal balance on the Class A Notes at that date in accordance with the
priority of payments. Class A Note scheduled principal payments are determined
on any payment date by reference to a multiple of the scheduled class percentage
for the Class A Notes on that date and the lesser of (a) the assumed portfolio
value as set forth in the Trust Indenture and (b) 105% of the adjusted portfolio
value, where the adjusted portfolio value of the fleet is calculated by
reference to the most recent appraised values. As has been the case since the
receipt of the aircraft appraisals in February 2002, 105% of the adjusted
portfolio value is less than the assumed portfolio value. Scheduled principal
payments on the Class A Notes rank after interest and minimum principal payments
on the Class A, B, C and D Notes in the priority of payments, but rank prior to
scheduled principal payments on the Class B and Class C Notes and step-up
interest





on the Class A Notes. Thus this redirection of cash flows will cause the
suspension of scheduled principal payments on the Class B and Class C Notes and
step-up interest on the Class A Notes. Despite the suspension of scheduled
principal payments on the Class B Notes, the Class B Notes are expected to
continue to receive minimum principal payments during the next twelve months in
accordance with the Class B Note minimum class percentage as set out in the
Trust Indenture. Class B Note minimum and scheduled principal payments are
determined on any payment date by reference to a multiple of the minimum and
scheduled class percentages for the Class B Notes and the assumed portfolio
value as set forth in the Trust Indenture. Class B Note minimum principal
payments rank prior to payments of interest and minimum principal on the Class C
and Class D Notes and scheduled principal payments on the Class A Notes. Minimum
principal payments are not expected to be made on the Class C Notes in the next
twelve months, as the Class C Notes have been paid down to the Class C Note
scheduled target principal balance which is currently approximately $6 million
lower than the Class C Note minimum target principal balance.

Based on AerCo's current expectation as to cash performance in the next twelve
months, we expect that we will have insufficient cash flows to pay down the
Class A Note principal balance currently outstanding to the Class A Note
scheduled target principal balance determined in accordance with the Trust
Indenture. Accordingly, we also believe that our cash flows will not be
sufficient to make scheduled principal payments on the Class B and Class C Notes
or payments of step-up interest on the Class A Notes. Beyond the next twelve
months, a number of factors, including the rate at which the appraised value of
our portfolio declines and the level of future cash flows, will be relevant in
determining whether we will be able to pay down the Class A Note principal
balance to the Class A Note scheduled target principal balance required and
accordingly resume scheduled principal payments on the Class B and Class C Notes
and payments of step-up interest on the Class A Notes. The greater the decline
in our future annual appraised values, particularly if combined with other
adverse factors, including a continued reduction in our cash flows, the more
likely it will be that our cash flows will continue to be redirected to the
Class A Notes as discussed above.

Further information regarding the appraisals

The appraisers ascertained the "base value" of each aircraft on the basis of an
open, unrestricted, stable market environment as of February 19, 2003 with a
reasonable balance of supply and demand, and with full consideration of each
aircraft's "highest and best use", presuming an arm's-length, cash transaction
between willing, able and knowledgeable parties, acting prudently, with an
absence of duress and with a reasonable period of time available for marketing,
adjusted to account for the maintenance status of each aircraft (with certain
assumptions as to use since the last reported status).

The 2003 Appraised Value does not reflect the values of leases, maintenance
reserves, security deposits or other collateral, if any, related to a particular
aircraft.

An appraisal is only an estimate of value and there can be no assurance that
proceeds received upon any sale of an aircraft would approximate the base value
of that aircraft.
