         P(a) = (P+B)(L + M) - P

         Where:

                      P(a) =           Airframe Price Adjustment.

                      L  =  .65 x ( ECI
                                  -----
                                        ECI(b))  where ECI(b) is the base year
                                                 index (as set forth in Table 1
                                                 of this Purchase Agreement)

                      M  =  .35 x ( ICI
                                  -----
                                        ICI(b))  where ICI(b) is the base year
                                                 index (as set forth in Table 1
                                                 of this Purchase Agreement)

                      P  = Airframe Price plus Optional Features Price (as set
                           forth in Table 1 of this Purchase Agreement).

                      B  = 0.005 x (N/12) x (P)    where N is the number of
                                                   calendar months which have
                                                   elapsed from the Airframe
                                                   Price Base Year and Month up
                                                   to and including the month of
                                                   delivery, both as shown in
                                                   Table 1 of the Purchase
                                                   Agreement. The entire
                                                   calculation of 0.005 X (N/12)
                                                   will be rounded to 4 places,
                                                   and the final value of B will
                                                   be rounded to the nearest
                                                   dollar.

                      ECI is a value determined using the U.S. Department of
                      Labor, Bureau of Labor Statistics "Employment Cost Index
                      for workers in aircraft manufacturing - Wages and
                      Salaries" (ECI code 3721W), calculated by establishing a
                      three-month arithmetic average value (expressed as a
                      decimal and rounded to the nearest tenth) using the values
                      for the fifth, sixth and seventh months prior to the month
                      of scheduled delivery of the applicable Aircraft. As the
                      Employment Cost Index values are only released on a
                      quarterly basis, the value released for the month of March
                      will be used for the months of January and February; the
                      value for June used for April and May; the value for
                      September used for July and August; and the value for
                      December used for October and November.

                      ICI is a value determined using the U.S. Department of
                      Labor, Bureau of Labor Statistics "Producer Prices and
                      Price Index - Industrial Commodities Index ", calculated
                      as a 3-month arithmetic average of the released monthly
                      values (expressed as a decimal and rounded to the nearest
                      tenth) using the values for the 5th, 6th and 7th months
                      prior to the month of scheduled delivery of the applicable
                      Aircraft.

                      As an example, for an Aircraft scheduled to be delivered
                      in the month of January, the months June, July and August
                      of the preceding year will be utilized in determining the
                      value of ECI and ICI.

Note:        i. In determining the values of L and M, all calculations and
             resulting values will be expressed as a decimal rounded to the
             nearest ten-thousandth.

             ii. .65 is the numeric ratio attributed to labor in the Airframe
             Price Adjustment formula.

             iii. .35 is the numeric ratio attributed to materials in the
             Airframe Price Adjustment formula.

             iv. The denominators (base year indices) are the actual average
             values reported by the U.S. Department of Labor, Bureau of Labor
             Statistics (base year June 1989 = 100). The applicable base year
             and corresponding denominator is provided by Boeing in Table 1 of
             this Purchase Agreement.

             v. The final value of P(a) will be rounded to the nearest dollar.

             vi. The Airframe Price Adjustment will not be made if it will
             result in a decrease in the Aircraft Basic Price.

2.       Values to be Utilized in the Event of Unavailability.

         2.1 If the Bureau of Labor Statistics substantially revises the
methodology used for the determination of the values to be used to determine the
ECI and ICI values (in contrast to benchmark adjustments or other corrections of
previously released values), or for any reason has not released values needed to
determine the applicable Airframe Price Adjustment, the parties will, prior to
the delivery of any such Aircraft, select a substitute from other Bureau of
Labor Statistics data or similar data reported by non-governmental
organizations. Such substitute will result in the same adjustment, insofar as
possible, as would have been calculated utilizing the original values adjusted
for fluctuation during the applicable time period. However, if within 24 months
after delivery of the Aircraft, the Bureau of Labor Statistics should resume
releasing values for the months needed to determine the Airframe Price
Adjustment, such values will be used to determine any increase or decrease in
the Airframe Price Adjustment for the Aircraft from that determined at the time
of delivery of the Aircraft.

         2.2 Notwithstanding Article 2.1 above, if prior to the scheduled
delivery month of an Aircraft the Bureau of Labor Statistics changes the base
year for determination of the ECI and ICI values as defined above, such re-based
values will be incorporated in the Airframe Price Adjustment calculation.

         2.3 In the event escalation provisions are made non-enforceable or
otherwise rendered void by any agency of the United States Government, the
parties agree, to the extent they may lawfully do so, to equitably adjust the
Aircraft Price of any affected Aircraft to reflect an allowance for increases or
decreases in labor compensation and material costs occurring since February of
the price base year shown in the Purchase Agreement which is consistent with the
applicable provisions of paragraph 1 of this Supplemental Exhibit AE1.

         2.4 If within 12 months of Aircraft delivery, the published index
values are revised due to an acknowledged error by the Bureau of Labor
Statistics, the Airframe Price Adjustment will be re-calculated using the
revised index values (this does not include those values noted as preliminary by
the Bureau of Labor Statistics). A credit memorandum or supplemental invoice
will be issued for the Airframe Price Adjustment difference. Interest charges
will not apply for the period of original invoice to issuance of credit
memorandum or supplemental invoice.

Note:        i. The values released by the Bureau of Labor Statistics and
             available to Boeing 30 days prior to the first day of the scheduled
             delivery month of an Aircraft will be used to determine the ECI and
             ICI values for the applicable months (including those noted as
             preliminary by the Bureau of Labor Statistics) to calculate the
             Airframe Price Adjustment for the Aircraft invoice at the time of
             delivery. The values will be considered final and no Airframe Price
             Adjustments will

<PAGE>

             be made after Aircraft delivery for any subsequent changes in
             published Index values, subject always to paragraph 2.4 above.

             ii. The maximum number of digits to the right of the decimal after
             rounding utilized in any part of the Airframe Price Adjustment
             equation will be 4, where rounding of the fourth digit will be
             increased to the next highest digit when the 5th digit is equal to
             5 or greater.

                               THE BOEING COMPANY

           Supplemental Exhibit EE1 to Purchase Agreement Number 2399

                               ENGINE ESCALATION,
                      ENGINE WARRANTY AND PATENT INDEMNITY

                                   relating to

                         BOEING MODEL 777-206ER AIRCRAFT

1.       ENGINE ESCALATION.

(a) The Aircraft Basic Price of each Aircraft set forth in Table 1 of the
Purchase Agreement includes an aggregate price for engines and all accessories,
equipment and parts provided by General Electric Aircraft Engines (GE). The
adjustment in Engine Price applicable to each Aircraft (Engine Price Adjustment)
will be determined at the time of Aircraft delivery in accordance with the
following formula:

         P(e) = [(P(b) + F)  x ( CPI / CPI(b)_)] - P(b)

where CPI(b) is the Engine Escalation Base Year Index as set forth in Table 1 of
the Purchase Agreement.

(b)  The following definitions will apply herein:

         P(e) =     Engine Price Adjustment

             P(b) = Engine Price (per Aircraft), as set forth in Table 1 of the
                    Purchase Agreement.

             F    = 0.005 x (N/12) x P(b) where N is the number of calendar
                    months which have elapsed from the Engine Price Base Year
                    and Month up to and including the month of delivery, both
                    as shown in Table 1 of the Purchase Agreement.

<PAGE>

         CPI =    L + ICI  (rounded to the nearest hundredth)

             L    = A value determined using the U.S. Department of Labor,
                    Bureau of Labor Statistics "Employment Cost Index Wages and
                    Salaries for Aircraft Manufacturing (SIC 3721)", calculated
                    as a 3-month arithmetic average of the released values
                    (expressed as a decimal and rounded to the nearest tenth)
                    using the values for the 12th, 13th and 14th months prior to
                    the month of scheduled Aircraft delivery then multiplied by
                    65% and rounded to the nearest thousandth.

             ICI  = A value determined using the U.S. Department of Labor,
                    Bureau of Labor Statistics "Producer Prices and Price Index
                    - Industrial Commodities Index ", calculated as a 3-month
                    arithmetic average of the released monthly values (expressed
                    as a decimal and rounded to the nearest hundredth) using the
                    values for the 12th, 13th and 14th months prior to the month
                    of scheduled delivery of the Aircraft, then multiplied by
                    35% and rounded to the nearest thousandth.

The Engine Price Adjustment will not be made if it would result in a decrease in
the Engine Price.

(c) The values of the Employment Cost Index Wages & Salaries (SIC 3721) and
Producer Prices and Price Index - Industrial Commodities Index used will be
those published as of a date 30 days prior to the first day of the scheduled
Aircraft delivery month to Customer. As the Employment Cost Index Wages and
Salaries for Aircraft Manufacturing (SIC 3721) values are only released on a
quarterly basis, the value released for the month of March will be used for the
months of January and February; the value for June used for April and May; the
value for September used for July and August; and the value for December used
for October and November. Such values will be considered final and no Engine
Price Adjustment will be made after Aircraft delivery for any subsequent changes
in published index values. If no values have been released for an applicable
month, the provisions set forth in Paragraph e, below, will apply. If prior to
delivery of an Aircraft, the U.S. Department of Labor, Bureau of Labor
Statistics changes the base year for determination of the L or ICI values as
defined above, such rebase values will be incorporated in the Engine Price
Adjustment calculation.

(d) If at the time of delivery of an Aircraft, Boeing is unable to determine the
Engine Price Adjustment because the applicable values to be used to determine L
and ICI have not been released by the U.S. Department of Labor, Bureau of Labor
Statistics, then: In the event the Engine Price escalation provisions are made
non-enforceable or otherwise rendered null and void by any agency of the United
States Government, GE agrees to meet jointly with Boeing and Customer (to the
extent such parties may lawfully do so) to adjust equitably the Aircraft Basic
Price of any affected Aircraft to reflect an allowance for increase or decrease
in labor compensation and material costs occurring since February of the base
price year which is consistent with the application provisions of this
Supplemental Exhibit EE1.

(e) If prior to delivery of an Aircraft, the U.S. Department of Labor, Bureau of
Labor Statistics substantially revises the methodology used for the
determination of the values to be used to determine the L and ICI values (in
contrast to benchmark adjustments or other corrections of previously released
values), Customer, Boeing and GE will, prior to delivery of such Aircraft,
select a substitute for such values from data published by the U.S. Department
of Labor, Bureau of Labor Statistics or other similar data reported by
non-governmental United States organizations, such substitute to lead in
application to the same adjustment result insofar as possible, as would have
been achieved by continuing the use of the original values as they may have
fluctuated during the applicable time period. Appropriate revisions of the
formula will be made as required to reflect any substitute values. However, if
within 24 months from delivery of the Aircraft, the U.S. Department of Labor,
Bureau of Labor Statistics should resume releasing values for the months needed
to determine the Engine Price Adjustment, such values will be used to determine
the increase or decrease in the Engine Price Adjustment determined at the time
of delivery of such Aircraft.

NOTE:    The factor (CPI divided by the base year index) by which the Engine
         Price is to be multiplied will be expressed as a decimal and rounded to
         the nearest thousandth. Any rounding of a number, as required under
         this Supplemental Exhibit EE1 with respect to escalation of the Engine
         Price, will 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 will be raised to the next higher number.

2.       ENGINE WARRANTY AND PRODUCT SUPPORT PLAN.

Boeing has obtained from GE the right to extend to Customer the provisions of
GE's warranty and product support plan (Warranty and Product Support Plan);
subject, however, to Customer's acceptance of the

                                          TREATMENT]
------------------------------------------------------------------------

These Mechanical Schedule Reliability Targets are based on an average flight
length of [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL
TREATMENT] per Scheduled Revenue Departure for Covered Aircraft in revenue
service operations. The Mechanical Schedule Reliability Targets are subject to
change based on changes in the Customer's actual Average Flight Length and other
factors under Customer's control.

3.       Remedial Action.

         3.1 Following the first four months of Scheduled Revenue Departures,
for any Analysis Period during which Customer has greater than six (6) Covered
Aircraft in revenue service, if Customer notifies Boeing that the Achieved
Mechanical Schedule Reliability for the Analysis Period is more than
[CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT] below the
Mechanical Schedule Reliability Target (Agreed Threshold Value) for such
Analysis Period, Boeing will for the Aircraft:

                  3.1.1 Investigate the circumstances and possible causes for an
Achieved Mechanical Schedule Reliability lower than the Agreed Threshold Value;

<PAGE>

                  3.1.2 Provide technical assistance to Customer in the form of
analysis and recommendations of a kind and nature which Boeing determines to be
best suited for improving the Achieved Mechanical Schedule Reliability;

                  3.1.3 Initiate a design review of the system, accessory,
equipment or part (other than engines and engine parts) which are determined by
Boeing to be the primary cause of an Achieved Mechanical Schedule Reliability
lower than the Agreed Threshold Value;

                  3.1.4 When in Boeing's judgment a redesign or modification is
indicated as a technically and economically practical means of improving the
Achieved Mechanical Schedule Reliability, redesign or cause the redesign of such
system, accessory, equipment or part; or offer such modification,

                  3.1.5 If such redesign or modification results in retrofit
kits being offered by Boeing or Boeing's suppliers, provide such kits or cause
such kits to be provided, at Customer's request, at no charge to Customer and
reimburse Customer's reasonable direct labor costs for incorporation of any such
kit manufactured to Boeing's detailed design. This offer will be valid for any
redesign or modification addressing improved reliability of the system,
accessory, equipment or part being identified as the main cause of Mechanical
Schedule Reliability below the Agreed Threshold Value that becomes available
within 5 years after Customer having made its notification in accordance with
above terms. The Covered Aircraft must still be experiencing Mechanical Schedule
Reliability below the Agreed Threshold Value at the time the retrofit kits
become available in order to qualify for the free retrofit kits.

Such reimbursement will be provided pursuant to Boeing Warranty (Article 11 of
Part 2 of Exhibit C, Product Assurance Document, of the AGTA); and

                  3.1.6 If Boeing determines that the design of engines or
engine parts is the primary cause of an Achieved Mechanical Schedule Reliability
lower than the Agreed Threshold Value, Boeing will, if requested by Customer,
take whatever reasonable action is permitted under Boeing's contracts with the
engine manufacturer in an effort to obtain correction of such design. This offer
will be valid for any redesign or modification addressing improved reliability
of the system, accessory, equipment or part being identified as the main cause
of the low Mechanical Schedule Reliability, and that comes available within five
years after Customer having made its notification in accordance with the above
terms.

4.       Interruption Exclusions.

An Interruption does not include any cancellation, turn-back, diverted landing
or delayed departure of any scheduled revenue flight of any Covered Aircraft
which is caused by any of the following events:

             (i)   Late arrival of an inbound flight;

             (ii)  Late return from out-of-service status;

             (iii) Operation, service, maintenance or overhaul of such Covered
Aircraft or any system, accessory, equipment or part (including engines)
installed thereon, in a manner other than in accordance with Customer's approved
instructions and requirements;

             (iv) Logistics problems such as lack of spare parts at stations
where spares could reasonably be expected to be available, as determined in
accordance with industry standard provisioning practices, or inordinate delays
in the availability of spares, unless such delays are caused by Boeing or other
appropriately trained personnel at any location where any maintenance of the
Covered Aircraft is performed;

             (v)  A malfunction caused by any extrinsic force such as foreign
object damage;

             (vi) Failure to utilize the FAA approved minimum equipment list
(MEL) to defer corrective maintenance, or failure to correct any deferred item
within the time period specified in such MEL;

             (vii) Buyer Furnished Equipment;

             (viii) Tires;

             (ix) Normal brake wear;

<PAGE>

             (x) Acts or omissions of Customer or any strikes or labor troubles
causing cessation, slowdown or interruption of work related to the operation or
maintenance of the Covered Aircraft; or

             (xi) Any other cancellation, turn-back, diverted landing or delayed
departure which cannot fairly be attributed to mechanical malfunction of the
Covered Aircraft, or any system, accessory, equipment or part (including
engines) installed on the Covered Aircraft.

             If a Covered Aircraft is used as a substitute for some other
aircraft or some other aircraft is used as a substitute for a Covered Aircraft
and the revenue flight affected by such substitution departs without a
cancellation, turn-back, diverted landing or delay greater than [CONFIDENTIAL
MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT], then no Chargeable
Schedule Interruption will be deemed to have occurred. If an Interruption occurs
as a result of a malfunction of the substitute aircraft/Covered Aircraft, such
Interruption will be charged against the aircraft/Covered Aircraft initially
scheduled for the flight rather than its substitute. An Interruption, which
affects a subsequent segment or flight for a Covered Aircraft, will count as
only one Interruption unless such Interruption is separate from and unrelated to
the initial Interruption.

5.        Administrative Requirements.

         5.1 Customer will provide status reports every month (Reporting
Period).

         5.2 The Customer's status reports shall include the data required to
calculate the Achieved Mechanical Schedule Reliability for each month of the
Reporting Period using the formulas described in Section 1.0, above, and a list
of the Chargeable Schedule Interruptions for the Reporting Period. Customer
shall submit such data to Boeing electronically in accordance with the
provisions of Boeing Document D6-81692.

         All data submitted pursuant to Subsection 5.2 will be addressed to the
attention of:

         MANAGER - IN-SERVICE DATA GROUP
         Boeing Commercial Airplanes
         P.0. Box 3707
         Seattle, Washington 98124-2207

         5.3 Customer claim reports will include the data described in
Subsection 5.2 above and sufficient data to substantiate any claimed Chargeable
Schedule Interruption. Customer will submit to Boeing reasonable proof that any
claimed Chargeable Schedule Interruption does in fact constitute a Chargeable
Schedule Interruption. In addition, Customer will maintain and submit to Boeing
such data as may reasonably be required to:

             (i) determine Achieved Mechanical Schedule Reliability,

             (ii) analyze the problems causing any claimed Chargeable Schedule
             Interruption, and

             (iii) when required, develop appropriate remedial action.

         5.4 Failure to file the status reports or provide the information as
specified in Subsections 5.1 through 5.3, above, will constitute an
acknowledgment by Customer that the Achieved Mechanical Schedule Reliability is
equal to or greater than the Agreed Threshold Value for such Analysis Period,
and Boeing will not be obligated to provide any of the remedies arising under
this Program for such Analysis Period.

         5.5 All reports submitted to Boeing will be addressed to the attention
of:

                         Director - Warranty & Supplier Product Support
                         Boeing Commercial Airplanes
                         P.0. Box 3707
                         Seattle, Washington 98124-2207

6.       Conditions and Limitations.

         6.1 If, to improve schedule reliability, Boeing or any Boeing supplier
issues service bulletins, service letters or other written instructions
(Instructions) or offers no-charge retrofit kits, Customer will accomplish such
Instructions or install such kits within a period of [CONFIDENTIAL MATERIAL
OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION
PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT] after availability of such
Instructions or kits at Customer's

<PAGE>

facility or such longer period as may be established by mutual agreement of the
parties. If Customer does not accomplish the Instructions or install the kits
within such time period, Chargeable Schedule Interruptions relating to the
systems, accessories, equipment or parts affected by such Instructions or kits
will be excluded from this Program from the date the Instructions or kits were
available at Customer's facility until such time as Customer notifies Boeing
that Customer has incorporated such Instructions or kits on all affected Covered
Aircraft.

         6.2 Boeing may inspect at all reasonable times Customer's maintenance
facilities and review its relevant maintenance programs and procedures. If
Boeing recommends in writing reasonable changes in Customer's maintenance
programs and procedures which would improve the Achieved Mechanical Schedule
Reliability and Customer does not effect such changes within [CONFIDENTIAL
MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT] after receiving
such written recommendations or such longer period as may be established by
mutual agreement of the parties, Boeing will have the right to redefine the
Chargeable Schedule Interruptions after the date Customer received such written
recommendations so as to eliminate interruptions which Boeing estimates result
from Customer's failure to effect the recommended changes within such time
period.

         6.3 If, for any Analysis Period, the actual Average Flight Length or
other factors affecting schedule reliability of the Covered Aircraft change
significantly, the Mechanical Schedule Reliability Target for such Analysis
Period will be appropriately adjusted by the parties.

         6.4 At Boeing's request, Customer will assign to Boeing any of
Customer's rights against any manufacturer of any system, equipment, accessory
or part installed in the Covered Aircraft as Boeing may reasonably require to
fulfill its obligations with respect to any remedy provided by Boeing hereunder.

         6.5 THE DISCLAIMER AND RELEASE and EXCLUSION OF CONSEQUENTIAL AND OTHER
DAMAGES provisions stated in Article 11 of Exhibit C of the AGTA apply to this
Program.

7.       Confidential Treatment.

         Customer understands that certain commercial and financial information
contained in this Letter Agreement are considered by Boeing as confidential.
Customer agrees that it will treat this Letter Agreement and the information
contained herein as confidential and will not, without the prior written consent
of Boeing, disclose this Letter Agreement or any information contained herein to
any other person or entity.

If the foregoing correctly sets forth your understanding of our agreement with
respect to the matters treated above, please indicate your acceptance and
approval below.

Provisioning Meeting will be agreed upon between the parties. However, Boeing
and Customer will use their best efforts to convene such meeting within 30 days
after execution of the Purchase Agreement.

3.       Initial Provisioning Documentation.

         3.1 Provisioning Data. Boeing will furnish Provisioning Data to
Customer on or about ninety (90) days after Aircraft implementation which is
approximately 12 months before delivery (Aircraft implementation is the date
engineering begins the detailed engineering designs and major suppliers start
locking in body requirements.) The Provisioning Data will be as complete as
possible and will cover Provisioning Items selected by Boeing for review by
Customer for initial provisioning for the Aircraft. The Provisioning Data will
set forth the prices for Provisioning Items which are Boeing Spare Parts and
such prices will be firm and remain in effect until the date or dates set forth
below in Paragraph 4.1, Boeing Spare Parts, by which orders must be placed with
Boeing. Boeing will, from time to time, until a date approximately 90 days
following delivery of the last Aircraft or until the delivery configuration of
each of the Aircraft is reflected in the Provisioning Data, whichever is later,
furnish to Customer revisions to the Provisioning Data.

         3.2 Provisioning IPC. Boeing will, on or about ninety (90) days after
Aircraft implementation which is approximately 12 months before delivery,
furnish to Customer a Boeing Illustrated Parts Catalog (IPC), hereinafter
referred to as the "Provisioning IPC". The Provisioning IPC will be as complete
as possible and will cover Provisioning Items selected by Boeing for review by
Customer for initial provisioning for the Aircraft. Boeing will, from time to
time, until a date approximately 90 days following delivery of the last
Aircraft, or until the delivery configuration of each of the Aircraft is
reflected in the Provisioning IPC, whichever is later, furnish to Customer
revisions to the Provisioning IPC.

         3.3             Buyer Furnished Equipment (BFE) Provisioning Data.

Attachment A

            Determination of Fleet Average Fuel Mileage Deterioration

For purposes of this Letter Agreement, the "Fleet Average Fuel Mileage
Deterioration" is the average cruise fuel mileage deterioration of the
Performance Retention Covered Aircraft. The determination of the Fleet Average
Fuel Burn Deterioration will be based on fuel mileage deterioration of
individual Performance Retention Covered Aircraft relative to their Baseline
Performance Level cruise fuel mileage performance as defined below.

1. Boeing will provide Customer with the Boeing Airplane Performance Monitoring
Program (APM) for data analysis. For purposes of this Letter Agreement, the
Model Reference Level cruise fuel mileage performance for the Performance
Retention Covered Aircraft shall be as set forth in the APM.

2. During the first thirty (30) days after each Performance Retention Covered
Aircraft begins revenue service (Initial Monitoring Period), Customer shall
acquire cruise fuel mileage data using the methodology described in Attachment
B. Customer will establish the average cruise fuel mileage level relative to the
Model Reference Level (Baseline Performance Level) for each Performance
Retention Covered Aircraft. The data sample for the Initial Monitoring Period
shall be comprised of [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH
THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL
TREATMENT] to assure that a representative level of fuel mileage is established.

3. During each of the [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH
THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL
TREATMENT] following completion of the Initial Monitoring Period (Subsequent
Monitoring Periods), Customer will continue to monitor the cruise fuel mileage
of the Aircraft using the methodology described in Attachment B. During the
Subsequent Monitoring Periods, one (1) Data Event should be recorded on each
flight when it is practicable to do so. The monthly sample for each Performance
Retention Covered Aircraft must include valid data for at least [CONFIDENTIAL
MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT] For the purposes of
this Letter Agreement, the "Current Performance Level" is defined as the average
of the cruise fuel mileage data relative to the Model Reference Level acquired
during the Subsequent Monitoring Period for each Performance Retention Covered
Aircraft. In the event insufficient data is available for a given month, the
Current Performance Level for such month shall be assumed the same as the
previous month.

4. The "Current Deterioration" (expressed as a percentage) for each Performance
Retention Covered Aircraft is the difference between the Current Performance
Level and the Baseline Performance Level.

5. The "Fleet Average Fuel Mileage Deterioration" (expressed as a percentage)
will be determined for each Subsequent Monitoring Period by summing the Current
Deterioration values as determined in Paragraph 4 above for each Performance
Retention Covered Aircraft in that calendar month and dividing by the number of
Performance Retention Covered Aircraft that comprised the sample.

<PAGE>

6. Customer will report the results of this analysis for the immediately
preceding calendar quarter to Boeing within 20 days of the end of each calendar
quarter following the date each Performance Retention Covered Aircraft is
delivered.

                  Cruise Fuel Mileage Performance Determination

Cruise performance data shall be obtained by using the Airplane Condition
Monitoring System (ACMS).

                  This data will be recorded during level flight cruise in
                  steady state conditions. The following data will be obtained
                  during each such data recording:

                  Initial C.G.
                  Initial Takeoff Gross Weight

KLM Royal Dutch Airlines

Subject:           Configuration Matters

Reference:         Purchase Agreement No. 2399 (the Purchase Agreement) between
                   The Boeing Company (Boeing) and KLM Royal Dutch Airlines
                   (Customer) relating to Model 777-206ER aircraft (the
                   Aircraft)

This letter agreement (Letter Agreement) amends and supplements the Purchase
Agreement. All terms used but not defined in this Letter Agreement have the same
meaning as in the Purchase Agreement.

1.  Development Changes. Boeing recognizes Customer's wish to receive early
notification of Development Changes (PRRs) applicable to its Aircraft to
evaluate the effect on maintenance and operation in a timely manner. In addition
to the notices required by Sections 4.1 and 4.3 of the AGTA, Boeing will furnish
Customer written notice of PRRs within [CONFIDENTIAL MATERIAL OMITTED AND FILED
SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
CONFIDENTIAL TREATMENT] after Boeing's commitment to incorporate them into
production. Notice will include: description of change, list of applicable
aircraft effectivities and, if appropriate, graphics. If Customer provides
Boeing written notification within [CONFIDENTIAL MATERIAL OMITTED AND FILED
SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR
CONFIDENTIAL TREATMENT] of receipt of a PRR notice that Customer does not want
the PRR, Boeing will investigate reversal of the PRR either by proposing a
priced master change for Customer's consideration or by deleting Customer's
Aircraft effectivity from the PRR at no charge. There can be no reversal for
PRRs that: (1) are reasonably required for Boeing to maintain efficient
production of all aircraft of that model type, (ii) would result in the loss of
any common type rating, (iii) are required to replace obsolete parts or (iv) are
imposed by either the Manufacturer's or Customer's respective regulatory agency
to be incorporated prior to delivery of the Aircraft.

2.  [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND
EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT]

3.  180 Minutes ETOPS. The 777 will be delivered with type design approval for
180 minute ETOPS.

4.           JAA Changes.

             4.1  JAA Type Certification. The Boeing model 777 has already
                  obtained its JAA Type Certification.

<PAGE>

             4.2  JAA Manufacturing Changes. A JAA Manufacturing Change is
defined as any change to an aircraft, data relating to an aircraft, or testing
of an aircraft required by the JAA to obtain an Export Certificate of
Airworthiness. Boeing agrees to incorporate into Customer's Aircraft all JAA
Manufacturer Changes required to be incorporated into the Aircraft by the JAA at
the time of Aircraft delivery. Customer will pay Boeing's charge for
incorporating all JAA Manufacturer Changes When a manufacturing change is both a
JAA Manufacturer Change and a FAA Manufacturer Change the provisions of Article
3.2.2 and 3.2.3 of the AGTA will take precedence. At the present time there are
no known JAA Manufacturer Changes that will impact the price of the Aircraft;
nor based, on our experience to date, does Boeing forsee any future divergency.


             4.3 JAR OPS 1 (JAR OPS Operator Changes). Boeing will deliver each
Aircraft with JAR OPS Operator Changes incorporated or, at Boeing's option, with
suitable provisions for the incorporation of such JAR OPS Operator Changes, and
Customer will pay Boeing's applicable charges.

5.  Assignment. The concessions described above are provided as a financial
accommodation to Customer in consideration of Customer's becoming the operator
of the Boeing aircraft, and cannot be assigned, in whole or in part, without the
prior written consent of The Boeing Company.

6.  Confidential Treatment. Customer and Boeing understand that certain
commercial and financial information contained in this Letter Agreement is
considered by Boeing and Customer as confidential. Customer and Boeing agree
that they will treat this Letter Agreement and the information contained herein
as confidential and will not, without the prior written consent of Boeing and
Customer, disclose this Letter Agreement or any information contained herein to
any other person or entity.
