ESCALATION ADJUSTMENT

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:



Pa =	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 11th, 12th and 13th 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.

|[**********] | [***]
|------------ | -----
|             | [***]



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 11th,
12th, and 13th 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.
| | ---- | ----------------------------------------------------------------------------------------

GUN-PA-04455-LA-1600105AGTA Terms UpdatesLA Page 11BOEING 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 11th, 12th and 13th 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 Pa 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.

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.

The Aircraft Basic Price
of each Aircraft set forth in Table 1 of the Purchase Agreement includes an aggregate price for General Electric Aircraft
GEnx series engines and all accessories, equipment and parts provided by the engine manufacturer (Engines). 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:



|[*****] | [*****]

Where:



|[*****] | [*****]

|[*****] | [*****]
|------- | -------



|[*****] | [*****]
|------- | -------
|        | [*****]



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 11th, 12th and 13th 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.

Where:



|[*****] | [*****]
|------- | -------



|[*****] | is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics, Producer Prices and Price Index - Industrial Commodities Index (BLS Series ID WPU03THRU15), 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 13th months prior to the month of scheduled delivery of the applicable Aircraft.
|------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|[*****] | [*****]
|------- | -------



Where:



|[*****] | 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 four (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 June, July and August of the preceding year will be utilized in determining
the value of [*****].



NOTE:



| | (i) | In determining the values of [*****], 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
Engine Price Adjustment formula.

| | (iii) | [*****] is the numeric ratio attributed to materials in
the Engine Price Adjustment formula.
| | ----- | --------------------------------------------------------------------------------------------



| | (iv) | The [*****]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 11th,
12th and 13th months prior to the Engine Price 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 [*****] will be rounded to the nearest

| | 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 [*****] 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 Exhibit EE1
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



| | 1. | Certain third party, commercial off-the-shelf software
products are available to perform various functions required in the Aircraft (COTS Software).
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | 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 (EULA), 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 EULA to any user to whom he transfers the product.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | 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.
| | -- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4. | 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.

| | 5. | Notwithstanding the provisions of Article 6.3 of the

Customer agrees to comply with all provisions of the applicable EULA’s, including without limitation the re-licensing of

| | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



3.3.          If

3.           Changes.



3.1.          After
Customer’s acceptance of this Letter Agreement, any changes to CSE may only be made by and between Boeing and the Supplier.
Any Customer request for changes to the CSE specification after execution of this Letter Agreement will be made in writing directly
to Boeing for approval and for coordination by Boeing with the Supplier. Any such change to the configuration of the Aircraft will
be subject to price and offerability through Boeing’s master change or other process for amendment of the Purchase Agreement.
Any Supplier price increase or decrease resulting from such change will be negotiated between Customer and Supplier.



3.2.          Boeing
and Customer recognize that the developmental nature of the CSE may require changes to the CSE or the Aircraft in order to ensure
(i) compatibility of the CSE with the Aircraft and all other Aircraft systems, and (ii) FAA certification of the Aircraft
with the CSE installed therein. In such event Boeing will notify Customer and recommend to Customer the most practical means for
incorporating any such change. If within fifteen (15) days after such notification Customer and Boeing cannot mutually agree
on the incorporation of any such change or alternate course of action, the remedies available to Boeing in Paragraph 6 will
apply.



4.           Supplier
Defaults.

If Boeing and Customer are unable to agree on an alternate Supplier or course of action within such time, the remedies available
to Boeing in Paragraph 6 will apply.



5.           Exhibits B

CSE is deemed to be BFE
for the purposes of Exhibit B, Customer Support Document, and Exhibit C, the Product Assurance Document, of the AGTA.



6.           Boeing’s

other remedies which Boeing may have by contract or under law, Boeing may:



6.1.          revise

and hold harmless Boeing from and against all claims and liabilities, including costs and expenses (including attorneys' fees)
incident thereto or incident to successfully establishing the right to indemnification, for injury to or death of any person or
persons, including employees of Customer but not employees of Boeing, or for loss of or damage to any property, including Aircraft,
arising out of or in any way connected with any nonconformance or defect in any CSE, or in the installation thereof or in the provision
of services hereunder, and whether or not arising in tort or occasioned in whole or in part by the negligence of Boeing. This indemnity
will not apply with respect to any nonconformance or defect caused solely by Boeing's installation of the CSE.



9.           Title
and Risk of Loss.



Title of CSE will remain
with Boeing until the Aircraft title is transferred to Customer. Risk of loss will remain with the entity that is in possession
of the CSE prior to Aircraft delivery

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. 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.



For clarity, Customer may
make a public announcement regarding Customer’s purchase of the Aircraft upon approval of Customer’s press release
by Boeing’s public relations department or other authorized representative.



1.4           Purchase
Agreement, Article 5.7. Negotiated Agreement; Entire Agreement.



For clarity, to the extent
there is any inconsistency between the terms of the AGTA and the Purchase Agreement, in each case, relating to the Aircraft, the
terms of this Purchase Agreement shall prevail.

| | -- | ---------------------------------------

flights are to demonstrate the function of the Aircraft only to Customer and not for marketing or commercial activities with Boeing’s
other customers.



| | 3. | AGTA Article 5.5 Special Aircraft Test Requirements.
| | -- | ----------------------------------------------------

the potential that flight and ground test hours on any Aircraft could [***************************]. As an accommodation for Customer’s

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 [***************************].



| | 4. | 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.

and Registration Documents. The first sentence of Article 1.1 shall be modified to read: “Airworthiness and Registration
Documents. Not later than [***************************] of each Aircraft, Customer will notify Boeing of the registration number
to be painted on the side of the Aircraft.” Customer and Boeing also agree to work together to minimize the impact related
to Customer’s notification to Boeing of the aircraft SELCAL and Mode-S information.

of Sanitary Construction. For clarification purposes and pursuant to Article 1.2.2, Customer has elected to receive the Certificate

6.4Article 4.1, Schedule of
Inspections, Article 4.2, Schedule for Demonstration Flights, and Article 4.3 Schedule for Customer’s Flight Crew. Articles
identify parties that participate in such actions, and the Civil Aviation Authority of China (CAAC) may also participate in these
actions. It’s noted that Boeing will provide advance notice of such actions.



6.5Article 4.4, Fuel Provided
by Boeing. In addition to the fuel provided by Boeing pursuant to Article 4.4, Boeing assists its customers with certain unique
services or accommodation items at [***************************]. If requested, Boeing provides oil and hydraulic fluid for the

|9. | FAA Airworthiness Directive Compliance Record Status”



6.7Article 4.7, Delegation of

| | 8. | Purchase Agreement – Redacted Versions.
| | -- | ---------------------------------------



Customer has concerns regarding

To accommodate Customer, Boeing will provide redacted version of the Purchase Agreement if requested by Customer for the purpose
of providing disclosure of the Purchase Agreement to relevant stock exchanges.



| | 9. | AGTA Terms Revisions.

AGTA terms revisions in
Letter Agreement 6-1165-CKR-1223 under Purchase Agreement No. 03107 will apply to Purchase Agreement No. 04455 where applicable.



| | 10. | Purchase Agreement Letter Agreement LA-1603083 Cabin
Systems Equipment (CSE).
| | --- | -----------------------------------------------------------------------------



10.1         For
clarification purposes concerning CSE changes, Customer may provide written request to Boeing for review and approval subject to

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.

GUN-PA-04455-LA-1603085Clarifications and UnderstandingsLA Page 4BOEING 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

| | 11. | Purchase Agreement Letter Agreement LA-1600111 Special

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

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 [********************************].



| | 12. | 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

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-1603085Clarifications and UnderstandingsLA Page 5BOEING 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.

it is not the intent of the parties to provide benefits hereunder that duplicate the benefits to be provided (a) by Boeing under
the Purchase Agreement, or any other agreement between Boeing and Customer, or (b) by the engine manufacturer under any agreement
between engine manufacturer and Customer, due to the Aircraft not satisfying any performance metric similar to the Mission Payload
Guarantee, Block Fuel Guarantee or any performance metric that otherwise impacts payload. Boeing may offset its obligation to provide
benefits hereunder against the benefits provided or to be provided to Customer by the engine manufacturer or Boeing pursuant to
such other guarantee.

Customer agrees that the
remedies contained in this Letter Agreement herein are Customer’s exclusive remedies for purposes of resolving all issues
