|1. | ***Base Year Formula.
|-- | ---------------------

Airframe and Optional Features price
adjustments (Airframe Price Adjustment) are used to allow prices to be stated in current year dollars at the signing of this Purchase Agreement and to adjust the amount to be paid by Customer at delivery for the effects of
economic fluctuation. The Airframe Price Adjustment will be determined at the time of Aircraft delivery in accordance with the following formula:



| | Pa= | (P)(L + M) - P
| | --- | --------------

Where:



| | Pa= | Airframe Price Adjustment.
| | --- | --------------------------

| | P = | Airframe Price plus the price of the Optional Features (as set forth in Table 11 of this Purchase Agreement).
| | --- | -------------------------------------------------------------------------------------------------------------

| | L = | .65 x (ECI
| | --- | ----------

| |  | ECIb)
| |  | -----

Where:

ECIbis the base year airframe escalation index (computed as the three month arithmetic average value of 103.1 for June, July and August of *** as set forth in Table 11 of
this Purchase Agreement);

ECI is a value determined using the U.S.
Department of Labor, Bureau of Labor Statistics, Employment Cost Index for NAICS Manufacturing  Total Compensation (BLS Series ID CIU2013000000000I), calculated by establishing a three-month arithmetic average value (expressed as a decimal and
rounded to the nearest tenth) using the values for the 11th, 12th, and 13thmonths 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 first quarter will be used for the months of January, February, and March; the value released for the second quarter will be used for the months of April, May, and June; the
value released for the third quarter will be used for the months of July, August, and September; the value released for the fourth quarter will be used for the months of October, November, and December.

M = .35 x (CPI

CPIb)

Where:

CPIbis the base year airframe escalation index (computed as the three
month arithmetic average value of 208.2 for June, July and August of *** as set forth in Table 11 of this Purchase Agreement); and

CPI is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics,
Consumer Price Index  All Urban Consumers (BLS Series ID CUUR0000SA0), calculated as a three (3) month arithmetic average of the released monthly values (expressed as a decimal and rounded to the nearest tenth) using the values for the 11th, 12th, and 13thmonths 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 July, the months of June, July, and August of the preceding year will be utilized in determining the value of ECI and CPI.

|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 CPI 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 CPI 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 consistent with the
applicable provisions of paragraph 1 of this Supplemental Exhibit AE1 in labor compensation and material costs occurring since August of the year prior to the price base year shown in the Purchase Agreement.

2.4 If within twelve (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
CPI 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 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.

(IAM Action). The IAM and Boeing agreed to a new, four year labor agreement ratified by the IAM membershi9 on November 1st. The IAM members agreed to return to work by November 10 .
