 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.

Aircraft will be subject to price and offerability through Boeing’s master change or other process for amendment of the Purchase Agreement.

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 SPE.

3.1 After Customer’s selection of the CSE, in accordance with the terms 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 selection by Customer 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 and if such changes are acceptable, shall be confirmed in writing between Boeing
and Customer. Any Supplier price increase or decrease resulting from such change will be negotiated and agreed 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 [*CTR] 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.

	Subject:	  	Clarifications and Understandings
		
	Reference:	  	Purchase Agreement No. PA-04676 (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 737-8 aircraft (Aircraft)

 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.

	Clarifications and Understandings	  	Page 1
		  	BOEING PROPRIETARY	  	

 

 
  
 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 5.7. 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.

Demonstration Flights. 
 For clarity, demonstration 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. 

Customer is concerned for the potential that flight and ground test hours on any Aircraft could [*CTR]. As an accommodation for Customer’s
concern, Boeing will notify Customer for any flight and ground testing that would [*CTR] hours on an Aircraft. 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 unfairly select Customer’s Aircraft when other aircraft are equally available and suitable for such tests. 

4. AGTA Article 6, Delivery. 
 Customer is
concerned events may occur affecting Customer’s ability to take delivery of an Aircraft on the scheduled delivery date. As an accommodation for Customer’s concern, Boeing will work with the Customer to adjust the delivery date for up to
[*CTR] Aircraft in the Purchase Agreement within the scheduled delivery month as long as Customer provides a notice to Boeing within              after receiving Boeing’s delivery
notice on that Aircraft, and, notwithstanding ) of the AGTA, Delay, Customer will [*CTR] for any of Boeing’s costs as a result of such adjustment.

 5. AGTA Article 8.2 Insurance. 

Customer is concerned about aircraft insurance requirements under Article 8.2 of the 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 [*CTR] for that specific aircraft after Customer has provided Boeing the notification of such post-delivery sale (AGTA Appendix III

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 BFE.” 

7. Purchase Agreement Exhibit B, Aircraft Delivery Requirements and Responsibilities. 

7.1 Article 1.1, Airworthiness and Registration Documents. The first sentence of Article 1.1 shall be modified to read:
“Airworthiness and Registration Documents. Not later than [*CTR] prior to delivery 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

 7.4 Article 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. 
 7.5 Article 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 [*CTR]. If requested, Boeing provides oil and hydraulic fluid for the ferry

confidential treatment of the Purchase Agreement when the relevant stock exchanges require certain disclosure from Customer. To accommodate Customer, Boeing will provide redacted version of the Purchase Agreement if requested by Customer for the
purpose of providing disclosure to relevant stock exchanges. 
 10. AGTA Terms Revisions.
