Ladies and Gentlemen:

In response to your request, Aircraft Information Services, Inc. (AISI) is
pleased to offer Morgan Stanley Aircraft Finance (MSAF) our opinion of the sight
unseen half life base value, half life current market value, adjusted base value
and adjusted current market value as of 30 September 2000 of sixty one aircraft
and one spare engine as defined and listed in reference (a), (b), (c) and (d)
data and Table I of this report.

1. METHODOLOGY AND DEFINITIONS

The standard terms of reference for commercial aircraft or engine value are
`half-life base market value' and `half-life current market value' of an
`average' aircraft or engine. Base value is a theoretical value that assumes a
balanced market while current market value is the value in the real market; both
assume a hypothetical average aircraft or engine condition. AISI value
definitions are consistent with the current definitions of the International
Society of Transport Aircraft Trading (ISTAT), those of 01 January 1994. AISI is
a member of that organization and employs an ISTAT Certified and Senior
Certified 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 or engines in `new' condition, `average half-life' condition, or in a
specifically described condition unique to a single aircraft or engine at a
specific time. An `average' aircraft or engine is an operable airworthy aircraft
or engine in average physical condition and with average accumulated flight
hours and cycles, with clear title and, for aircraft, a 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 the
title and, for aircraft, a 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 the aircraft or engine's 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. AISI defines engine `zero time since
overhaul' condition to be that of an engine fresh from an engine heavy
maintenance shop visit which overhauled all engine modules or all engine
compressor and combustor/turbine stages as appropriate, with all life-limited
components at half-life. It should be noted that AISI and ISTAT value
definitions apply to a transaction involving a single aircraft or engine, and
that transactions involving more than one aircraft or engine are often executed
at considerable and highly variable discounts to a single aircraft or engine
price, for a variety of reasons relating to an individual buyer or seller.

AISI defines a `current market value', which is synonymous with the older term
`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 or engine 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 or engine is used, the status of supply and demand for the
particular aircraft or engine 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 or engine.

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.

No physical inspection of the Aircraft or Engine or their essential records was
made by AISI for the purposes of this report, nor has any attempt been made to
verify information provided to us, which is assumed to be correct and applicable
to the Aircraft.

Given the relatively broad range of values for transactions for an engine type
the meaning of `base value' for used engines is open to broad interpretation.
Normally base value is derived from historical normalized current market values
with manufacturer's list price as a start point, while current market value is
deduced directly from recent transactions. For used engines there are seldom
sufficient historical transactions to permit the same derivation of engine base
values as is possible for aircraft base values. In our opinion the used engine
market is will be close to current market values for most engine types. AISI's
definitions of engines are as follows:

BARE ENGINE
AISI defines a BARE ENGINE as an engine without accessories, but complete with
all engine related air, hydraulic and electrical lines which are not directly
part of accessories.

ENGINE ACCESSORIES
AISI defines a BASIC QEC (quick engine change set of equipment) as being
composed of two subsets of equipment according to original sources of
procurement.

- -    EBU (engine build up) items which include all accessories, connecting
     lines, engine mounts, tubes and ducting. When procured from sources other
     than the airframe manufacturers, these items are referred to as baseline
     QEC items.

- -    BFE (buyer furnished equipment) items which include the starter, valves,
     IDG and hydraulic pump.

Note the above subset definitions are valid for new engines and QEC kits; once
the engine and QEC are used, the distinctions between EBU and BFE becomes
irrelevant and are referred to collectively as basic QEC.

ENGINE WITH QEC
The engine with basic QEC is often referred to as the "demountable engine" by
manufacturers and as a "high neutral QEC" by airlines. The engine plus basic QEC
does not include engine inlet cowl, centerbody, nozzle, or plug. There will be
some variation in basic QEC inventory from engine type to type, and from
position to position.

AISI defines an engine with FULL QEC as a basic QEC engine plus inlet cowl,
centerbody, nozzle, and plug. Manufacturers often refer to this configuration as
a "fully demountable engine". There will be some variation in full QEC inventory
from engine type to type, and from position to position. None of the above
descriptions include the thrust reverser, which is valued separately.

2. VALUATION

Adjustments from half life have been applied based on the current maintenance
status of the Aircraft as indicated in the Maintenance Detail sheets supplied by
the client 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
limited information provided, all engines are considered to be in half life
condition.

All hours and cycle information provided for airframe, C Check, D Check, and
gear have been projected from the Maintenance Detail sheet dates to 30 September
2000 based on a daily utilization factor calculated for each aircraft: Per the
clients request, all maintenance work which became due as a result of projecting
the hour and cycle information to 30 September 2000 was assumed to have been
completed and a new cycle started.

It is our considered opinion that the half life base values, half life current
market values, adjusted base values, and adjusted current market values of the
Aircraft and Engine as of 30 September 2000 are as follows in Table I subject to
the assumptions, definitions, and disclaimers herein.
