contrast to benchmark adjustments or other corrections of
previously published data) or (ii) discontinues publication of
any of the data referred to above, Pratt & Whitney Aircraft
(P&WA) agrees to meet with Boeing and jointly select a substitute
for the revised or discontinued data, such substitute data to
lead in application to the same adjustment result, insofar as
possible, as would have been achieved by continuing the use of
the original data as it may have fluctuated had it not been
revised or discontinued.  Appropriate revision of the Engine
Price Adjustment provisions set forth above shall be made to
accomplish this result for affected Engines.

In the event the Engine Price Adjustment escalation provisions of
this Agreement are made non-enforceable or otherwise rendered
null and void by any agency of the United States Government, P&WA
agrees to meet with Boeing and jointly agree, to the extent that
they may lawfully do so, to adjust equitably the Purchase Price
of any affected Engine(s) to reflect an allowance for increases
in labor, material and fuel costs that occurred from December,
1994 to the seventh month preceding the month of scheduled
delivery of the applicable Aircraft.

NOTE:  Any rounding of a number, as required under this Exhibit D
       with respect to escalation of the Engine price, shall be
       accomplished as follows: if the first digit of the portion
       to be dropped from the number to be rounded is five or
       greater, the preceding digit shall be raised to the next
       higher number.

                    ---------------------------------

          2.5.1     For the Model 747 and 757, Boeing will work with
Buyer to pre-implement a set of either long lead, or a complete
set of, hardware for a new simulator in the required simulator
tail number.  Buyer will submit to Boeing a "coverage" P/O which
will not be executed until selection of a simulator manufacturer
to be used in this pre-implementation.  Boeing also pre-
implements generic simulator long-lead hardware that may be
allocated to Buyer with appropriate notification.  Kits are
allocated based on notification, lead times, training needs,
airplane delivery, etc.  Notification must occur in a timely
fashion or kits may not be available as required by Buyer.  Once
the kit is allocated, Buyer will then have first right of refusal
on it.  Only hardware requirement dates of greater than six
months on receipt of order will be accepted by Boeing for
hardware required in addition to allocated pre-implemented kit.

          2.5.2     Required Boeing proprietary hardware may be
purchased at the then-current Boeing Spares Catalog prices.  In
the event that Buyer elects to submit Purchase Orders to Boeing
for selected vendor hardware, such Purchase Orders shall be
processed by Boeing in the same manner as sustaining spares for
the Aircraft, in accordance with the applicable terms and
conditions of Spare Parts General Terms Agreement No. 22, dated
October 25, 1967 as amended and supplemented.
