Subject: Half Life and Adjusted Base and Current Market Value Opinion - 221
         Aircraft.
         AISI File number: A8S007BVO

Dear Sirs:

In response to your request, Aircraft Information Services, Inc. (AISI) is
pleased to offer our opinion to the above addressees of the half life and
adjusted base and current market values of the Fleet of Aircraft as identified
in Table I (the "Aircraft").

1.  METHODOLOGY AND DEFINITIONS

The historical standard term of reference for commercial aircraft value has
been "half-life fair market value" of an "average" aircraft. However, "fair
market value" could mean a fair value in the given market or a value in a
hypothetical "fair" or balanced market, and the two

                                                                     [AISI LOGO]
                                                                      ----

definitions are not equivalent. Recently, the term 'base value' has been created
to describe the theoretical balanced market condition and to avoid the
potentially misleading term 'fair market value' which has now become synonymous
with the term 'current market value' or a 'fair' value in the actual current
market. AISI value definitions are consistent with those of the International
Society of Transport Aircraft Trading (ISTAT) of 01 January 1994; AISI is a
member of that organization and employs an ISTAT Certified Senior Aircraft
Appraiser.

AISI defines a 'base value' as that of a transaction between equally willing and
informed buyer and seller, neither under compulsion to buy or sell, for a single
unit cash transaction with no hidden value or liability, and with supply and
demand of the sale item roughly in balance. Base values are typically given for
aircraft in 'new' condition, 'average half-life' condition, or in a specifically
described condition unique to a single aircraft at a specific time. An 'average'
aircraft is an operable airworthy aircraft in average physical condition and
with average accumulated flight hours and cycles, with clear title and standard
unrestricted certificate of airworthiness, and registered in an authority which
does not represent a penalty to aircraft value or liquidity, with no damage
history and with inventory configuration and level of modification which is
normal for its intended use and age. AISI assumes average condition unless
otherwise specified in this report. 'Half-life' condition assumes that every
component or maintenance service which has a prescribed interval that determines
its service life, overhaul interval or interval between maintenance services, is
at a condition which is one-half of the total interval. It should be noted that
AISI and ISTAT value definitions apply to a transaction involving a single
aircraft, and that transactions involving more than one aircraft are often
executed at considerable and highly variable discounts to a single aircraft
price, for a variety of reasons relating to an individual buyer or seller.


AISI defines a 'current market value' or 'fair market value' as that value which
reflects the real market conditions, whether at, above or below the base value
conditions. Assumption of a single unit sale and definitions of aircraft
condition, buyer/seller qualifications and type of transaction remain unchanged
from that of base value. Current market value takes into consideration the
status of the economy in which the aircraft is used, the status of supply and
demand for the particular aircraft type, the value of recent transactions and
the opinions of informed buyers and sellers. Current market value assumes that
there is no short term time constraint to buy or sell.

AISI encourages the use of base values to consider historical trends, to
establish a consistent baseline for long term value comparisons and future value
considerations, or to consider how actual market values vary from theoretical
base values. Base values are less volatile than current market values and tend
to diminish regularly with time. Base values are normally inappropriate to
determine near term values. AISI encourages the use of current market values to
consider the probable near term value of an aircraft.

AISI determines an 'adjusted market value' by determining the value of known
deviations from half-life condition, which may be better or worse than half-life
condition, and to account for better or worse than average physical condition,
and the inclusion of additional equipment, or absence of standard equipment. Our
opinion of the adjusted base values of the Aircraft are derived from information
and specifications supplied by GPA Group plc. No physical inspection of the
Aircraft or their essential records was made by AISI for the purposes of this
report.

2.   VALUATION

Adjustments from half life have been applied based on the current maintenance
status of the Aircraft as indicated in the Aircraft General Specification sheets
supplied to AISI and in accordance with standard AISI methods. Adjustments are
calculated only where there is sufficient information to do so, or where
reasonable assumptions can be made.

With regard to airframe and gear maintenance, if no time between check/overhaul
(TBO) or time since check/overhaul (TSO) information was provided, and if the
total hours/cycles of the airframe do not exceed the TBO limits then the total
hours/cycles of the airframe were assumed to be the TSO. This was typical of
newer aircraft. If no information was provided and if the TSO could not be
calculated, then half life was assumed.

With regard to the engines, due to the lack of information provided, all engines
are considered to be in half life condition.

All hours and cycle information provided for airframe, C Check, D Check, gear
and engines have been projected from the Aircraft General Specification sheet
dates to 23 January 1998 based on a daily utilization factor calculated for each
aircraft.

It is our considered opinion that the half life and adjusted base and current
market values of the Aircraft are as follows in Table I subject to the
assumptions, definitions, and disclaimers herein.
