1.3.3 Export Declaration—U.S. If the Aircraft is intended to be exported from the United States following delivery, and (i) Customer is a non-U.S. customer, Boeing will file an export declaration electronically with U.S. Customs and Border Protection (CBP), or (ii) Customer is a U.S. customer, it is the responsibility of the U.S. customer, as the exporter of record, to file the export declaration with CBP.

2. INSURANCE CERTIFICATES.

AIRFRAME AND OPTIONAL FEATURES

ESCALATION ADJUSTMENT

relating to

BOEING MODEL 737-8 AIRCRAFT

1. 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:

[*CTR]

Where:

[*CTR]

[*CTR]

[*CTR]

Where:

[*CTR] is the base year airframe escalation index (as set forth in Table 1 of this Purchase Agreement);

ECI is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics, [*CTR] calculated by establishing a [*CTR] value (expressed as a decimal and rounded to the nearest tenth) using the values for the [*CTR] 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 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.

GUN-PA-04676-AE1		Page 2
	BOEING PROPRIETARY

[*CTR]

Where:

[*CTR] is the base year index (as set forth in Table 1 of this Purchase Agreement); and

[*CTR] is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics, [*CTR] monthly [*CTR] tenth) using the values for the prior to the month of scheduled delivery of the applicable Aircraft.

[*CTR]

[*CTR]        [*CTR]

Where:

[*CTR] 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 [*CTR] will be rounded to 4 places, and the final value of [*CTR] will be rounded to the nearest dollar.

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 [*CTR]

Note:

(i) In determining the values of [*CTR], all calculations and resulting values will be expressed as a decimal rounded to the nearest ten-thousandth.

(ii) [*CTR] numeric ratio attributed to labor in the Airframe Price Adjustment formula.

(iii) [*CTR] 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. The actual average values are calculated as a [*CTR] arithmetic average of the released monthly values (expressed as a decimal and rounded to the nearest tenth) using the values for the [*CTR] months prior to the airframe base year. The applicable base year and corresponding denominator is provided by Boeing in Table 1 of this Purchase Agreement.

GUN-PA-04676-AE1		Page 3
	BOEING PROPRIETARY

(v) The final value of [*CTR] 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 [*CTR] 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 [*CTR] 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 [*CTR] 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 [*CTR] prior to the price base year shown in the Purchase Agreement.

2.4 If within [*CTR] 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.

GUN-PA-04676-AE1		Page 4
	BOEING PROPRIETARY

Note:

(i) The values released by the Bureau of Labor Statistics and available to Boeing [*CTR] prior to the first day of the scheduled delivery month of an Aircraft will be used to determine the [*CTR] 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 five (5) or greater.

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

1. Clarifications and Understandings. The following clarifications and understandings pertain to the indicated provisions of the Purchase Agreement:

1.1 Purchase Agreement, Article 1. Quantity, Model and Description.

The Civil Aviation Authority of China (CAAC) has indicated to the FAA that Boeing’s manufacturing procedures meet the bi-lateral agreements between the responsible parties. The FAA uses FAR Part 25 to establish the Type Certificate. Similarly, the CAAC uses its CCAR 25 for its Type Certificate. CCAR 25 is not identical to the FAA, but the CAAC considers both to be sufficiently equivalent to recognize the FAA Type Certificate to be valid.

In the issuance of an Export Certificate of Airworthiness, the FAA complies with any additional CAAC requirements through the use of Advisory Circular 21-2 (AC 21-2). Such additional requirements are documented by the FAA in AC 21-2.
