AIRFRAME AND OPTIONAL FEATURES

relating to

BOEING MODEL 787-9 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:

[************************]

Where:

P_a = Airframe Price Adjustment.

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

[**********]	[***]
	[***]

Where:

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

[******] is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics, Employment Cost Index for [************************************] [*******************************], calculated by establishing a three-month arithmetic average value (expressed as a decimal and rounded to the nearest tenth) using the values for the 11^th, 12^th and 13^th 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.

BOEING PROPRIETARY

[**********]	[***]
	[***]

Where:

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

[***] is a value determined using the U.S. Department of Labor, Bureau of Labor [************************]**************], 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 11^th, 12^th, and 13^th months prior to the month of scheduled delivery of the applicable Aircraft.

[************************]

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

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)

[***] is the numeric ratio attributed to labor in the Airframe Price Adjustment formula.

(iii)

[***] is the numeric ratio attributed to materials in the Airframe Price Adjustment formula.

“[***]” This information is subject to confidential treatment and has been omitted and filed separately with the commission

XXX-XX-00000-XX-0000000
XXXX Terms Updates	LA Page 11
BOEING PROPRIETARY

(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 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 11^th, 12^th and 13^th 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.

(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 twenty-four (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 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.

BOEING PROPRIETARY

Note:

(i)

The values released by the Bureau of Labor Statistics and available to Boeing thirty (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 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.

Where:

[*****]

is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics, Employment Cost Index for NAICS Aircraft Manufacturing - Wages and Salaries (Series ID CIU2023211000000I), calculated by establishing a three (3) month arithmetic average value (expressed as a decimal and rounded to the nearest tenth) using the values for the 11^th, 12^th and 13^th 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.

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 [*****] 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 Engine Price Adjustment, General Electric Aircraft agrees to meet jointly with Boeing and the Customer (to the extent such parties may lawfully do so) 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 [*****] after delivery of the Aircraft, the 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 any increase or decrease in the Engine Price Adjustment for the Engine 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 [*****] as defined above, such re-based values will be incorporated in the Engine 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 Engine Price of any affected Aircraft to reflect an allowance for increases or decreases consistent with the applicable provisions of paragraph 1 of this Supplemental Xxxxxxx XX0 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 [**************] of Aircraft delivery, the published index values are revised due to an acknowledged error by the Bureau of Labor Statistics, the Engine 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 Engine 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 thirty (30) days prior to the first day of the scheduled delivery month of an Aircraft will be used to determine the [*****] values for the applicable months (including those noted as preliminary by the Bureau of Labor Statistics) to calculate the Engine Price Adjustment for the Aircraft invoice at the time of delivery. The values will be considered final and no Engine 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 Engine Price Adjustment equation will be four (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.

Recitals

Certain third party, commercial off-the-shelf software products are available to perform various functions required in the Aircraft (COTS Software).

The industry practice with respect to COTS Software is to permit manufacturers to install the software in products for sale to customers. The manufacturer is required to pass to the customer an End User License Agreement (XXXX), which covers the right to use the COTS Software. The EULA’s also require each user of the product to further license the software and pass the XXXX to any user to whom he transfers the product.

Because of the described industry practice with respect to COTS Software, Boeing does not acquire title to COTS Software and cannot pass title to COTS Software at the time of delivery of the Aircraft.

Therefore, the parties desire to amend certain provisions of the Purchase Agreement to properly reflect the respective rights and obligations of the parties with respect to the COTS Software included in the Aircraft.

GUN-PA-04455-LA-1600112
XXXX Special Matters	LA Page 1
BOEING PROPRIETARY

Agreement

Prior to delivery of the Aircraft, Boeing will make available to Customer copies of all EULA’s applicable to the Aircraft, and Customer agrees to comply with all provisions of the applicable EULA’s.

Notwithstanding the provisions of Article 6.3 of the AGTA, at delivery of each Aircraft, Boeing will provide Customer [*******************************************].

In connection with any sale or other transfer of the Aircraft, Customer agrees to comply with all provisions of the applicable EULA’s, including without limitation the re-licensing of the software to Customer’s transferee and the flow down within such license of the further requirement that Customer’s transferee comply with and flow to other transferees the obligations of the XXXX.

12. Advance Payments for the Aircraft – Due on the Effective Date of the Purchase Agreement.

It is understood that Customer’s ability to make advance payments described in Articles 4.2 and 4.3 of the Purchase Agreement may be impacted due to monetary issues.

Subject:	Clarifications and Understandings

Reference:	Purchase Agreement No. PA-04455 (Purchase Agreement) between The Boeing Company (Boeing) and China Southern Airlines Company Limited (Customer) with China Southern Airlines Group Import and Export Trading Corp., Ltd. (Consenting Party) relating to Model 787-9 aircraft (Aircraft)

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. As set forth in the AGTA, Boeing will manufacture each Aircraft to conform to the appropriate Type Certificate issued by the United States Federal Aviation Administration (FAA) for the specific model of aircraft and will obtain from the FAA and furnish to Buyer at delivery of each Aircraft either a Standard Airworthiness Certificate or an Export Certificate of Airworthiness issued pursuant to Part 21 of the Federal Aviation Regulations.

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.

1.2 Purchase Agreement, Article 4. Payment.

Article 4.2 refers to payments due on the “effective date” of the Purchase Agreement. Article 4.3 refers to payments due “upon signing” of the Purchase Agreement. The effective date of the Purchase Agreement is the day it is signed by Boeing, Customer and the Consenting Party. Such date appears in the first sentence of the Purchase Agreement and again just above the signature blocks of the parties to the Purchase Agreement. For clarification purposes, Boeing will provide invoices in advance for all payments due under the Purchase Agreement to facilitate payment by Customer.

1.3 Purchase Agreement, Article 5.6. Public Disclosure.

Customer and Boeing agree to discuss the matter if tests are for purposes other than the flight and ground tests described in Article 5.5 (i) and (ii) of the AGTA. For the avoidance of doubt, Boeing flight and ground tests will not [***************************].

AGTA Article 8.2 Insurance.

Customer is concerned about aircraft insurance requirements under Article 8.2 of AGTA after Customer has sold an Aircraft to a new owner. For clarity, after Customer has transferred the title of an Aircraft to the new owner, Customer will be released from [***************************] for that specific Aircraft after Customer has provided Boeing the notification of such post-delivery sale (AGTA Appendix III provides such a reference notice). Notwithstanding the foregoing, Customer is not released from its obligation under Article 8.2 of AGTA any period which Customer has control or possession of an Aircraft.

10.1 For clarification purposes concerning CSE changes, Customer may provide written request to Boeing for review and approval subject to price and offerability through Boeing’s master change or other process for amendment of the Purchase Agreement. In addition, Boeing agrees to work with Customer and suppliers in the event Boeing determines CSE changes are necessary to fulfill the Boeing’s obligations under the Purchase Agreement.

“[***]” This information is subject to confidential treatment and has been omitted and filed separately with the commission

GUN-PA-04455-LA-1603085
Clarifications and Understandings	LA Page 4
BOEING PROPRIETARY

10.2 Delay of an aircraft delivery caused by an event or events set out in Section 7.1 of the AGTA No. AGTA-GUN is subject to the provisions under section 7 of the AGTA. Delay of an aircraft delivery as defined in the Non-Excusable Delay Letter Agreement is subject to the provisions of the Non-Excusable Delay Letter Agreement LA-1600114. This applies to all Boeing aircraft and Boeing’s obligations under the Purchase Agreement including but not limited to Boeing obligations under the CSE Letter Agreement LA-1603083.

10.3 Article 8. Customer’s Indemnification of Boeing. This last sentence of CSE Letter Agreement LA-1603083 Article 8 shall be modified to read: “This indemnity will not apply with respect to any nonconformance or defect caused solely by Boeing's storage, handling, and installation of the CSE.”

11.

Purchase Agreement Letter Agreement LA-1600111 Special Escalation Program.

11.1 Customer has concerns regarding the length of time period Boeing [**********] Escalation Adjustment for the Airframe, Price and Optional Features of each Aircraft in Table 1 of the Purchase Agreement. For the avoidance of doubt [****************************] by mutual agreement between Customer and Boeing in the event of [*************************].

11.2 In the event the Aircraft with the Nominal Delivery Month in July 2020 is rescheduled as [*******************] in accordance with the Open Configuration Matters LA-1600116, Article 1.1, then the [***************] will be [********************************].

CAAC regulatory information

It is recognized that the Civil Aviation Authority of China (CAAC) works with certain aircraft-related information, including Type Certificate Data Sheets (TCDS), Validation of Type Certificate Data Sheets (VTCDS), Aircraft Letter of Definition (ALOD) in order to issue to Customer the necessary aircraft certificates for operating the Aircraft in China. Boeing agrees to work with the relevant regulatory entities on a timely basis to support the process providing such information to the CAAC.

13.

Assignment

13.1 Notwithstanding any other provisions of the Purchase Agreement, whereby this clause takes precedence, if Customer requests to assign an Aircraft under the Purchase Agreement to an assignee which Customer or China Southern Airlines Holding Company directly controls or holds [***************************], Customer will work with Boeing in accordance with the lead-time and charges required for configuration changes and Boeing will not unreasonably withhold its consent to the assignment of Customer’s rights and obligations under the Purchase Agreement as relates to the specific Aircraft or post-delivery entitlements (collectively “Assigned Rights”), including but not limited to all rights and obligations with respect to advance payments already paid to Boeing under the Purchase Agreement.

“[***]” This information is subject to confidential treatment and has been omitted and filed separately with the commission

GUN-PA-04455-LA-1603085
Clarifications and Understandings	LA Page 5
BOEING PROPRIETARY

13.2 Any such assignment will be in the form acceptable to Boeing (AGTA Appendix II provides such a reference form), including the undertaking by Customer to be bound by the DISCLAIMER AND RELEASE and EXCLUSION OF CONSEQUENTIAL AND OTHER DAMAGES provisions set forth in Article 11 of Part 2 of Exhibit C to the AGTA.

14.

Regulatory Approval, Validated Type Certificate (VTC).

It is recognized that obtaining the 787-9 Validated Type Certificate (VTC) is necessary for Customer to import and use the Aircraft in China. Customer has requested that Boeing take responsibility for obtaining the VTC for the 787-9. While Boeing recognizes Customer’s concern regarding VTC for the 787-9, Boeing is not able to accept responsibility for obtaining the VTC from the CAAC. If the lack of VTC approval results in the delay of an Aircraft delivery, such a delay would be an Excusable Delay (as defined in Article 7.1 of the AGTA). However, Boeing commits to support the process of obtaining the VTC and Customer’s efforts (as applicable) towards the same as described herein. In support of obtaining VTC approval, Boeing will be responsible for: (1) assessing the applicable regulatory requirements, (2) generating data and analysis to reasonably support the approval requirements, (3) submitting such information to the applicable regulatory agency, and (4) supporting discussions with regulators to assist in the evaluation of the Boeing submittal.

This will be accomplished through an Option (similar to Options [***************************] in Exhibit A-1 and Exhibit A-2 of Purchase Agreement No. PA-3263) to support an Export Certificate of Airworthiness for the Aircraft.

15.

Aircraft and Engines.

15.1 Customer has concerns regarding the General Electric GEnx type engines installed in the Aircraft at the time of delivery. For clarity, Boeing will manufacture each Aircraft and install the appropriate engines to conform to the appropriate Type Certificate issued by the FAA and in accordance with Boeing’s production process and requirement.

15.2 At the time of delivery, if Boeing and Customer mutually agree that the condition of an Aircraft requires borescope inspections, such inspection will be conducted in accordance with the relevant aircraft engine maintenance procedures.

15.3 The Aircraft Basic Price contained in the Purchase Agreement reflects an Engine Price per Aircraft [*****************************] representing [********************************] obtained by Boeing for the benefit of Customer from the engine list price per Aircraft of [************************************]. This discount does not preclude Customer from negotiating directly with the engine manufacturer [************************], as well as for technical and/or support issues.
