 AIRFRAME AND OPTIONAL FEATURES 

ESCALATION ADJUSTMENT 

relating to 
 BOEING
MODEL 777-300ER AIRCRAFT 
 1. Formula. 

Airframe and Optional Featuresprice 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: 

1111 is the base year airframe escalation index (as set forth in Table 1 of this Purchase Agreement); 

[*CTR] 
 - is a value determined using the U.S. Department of
Labor, Bureau of Labor Statistics, [*CTR] ca cu a e y es a 1s 1ng a [*CTR] arithmetic average value (expressed as a decimal and rounded to the nearesenth) using the values for [*CTR] months prior to the month of scheduled delivery of the applica e
ircra. s 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-04666-AE1	  		  	Page 2
		  	BOEING PROPRIETARY	  	
		  		  	









 [*CTR] 

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 [*CTR], calculated as
a [*CTR] month arithmetic average of the released monthly values (expressed ressed as a dec1ma and rounded to the nearest tenth) using the values for the [*CTR] months prior to the month of scheduled delivery of the applicable Aircraft. 

II [*CTR] 
 Where: 

I is the number of calendar months which have elapsed from the Airframe Price base year and month up to and including the month of
                    shown in Table 1 of the Purchase Agreement. The entire calculationo-
                    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 J nd August of the preceding year will be utilized in determni
ing the value of _                     _ 
 Note: 

 

	 	(i)	In determni ing the values of L and M, all calculations and resulting values will be expressed as a decimal rounded to the nearestten-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. 

  

	 	(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
-                     month arithmetic average of the released moiiT!iiyvaTu’ es (expressed as a decimal and rounded to the nearest tenth) using
the values for the -                     months prior to the airframe base            
able base year and corresponding denominator is provided by Boeing in Table 1 of this Purchase Agreement. 


  

					
	GUN-PA-04666-AE1	  		  	Page 3

	 	(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 [*CTR] 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 [*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] months prior to the price base year shown in the Purchase Agreement. 

2.4 If within [*CTR] 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 [*CTR] prior to the first day of the scheduled delivery month of an Aircraft will be used to determine the [*CTR] 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.

	Subject:	Payment Matters 

  

	Reference:	 Purchase Agreement No. PA-04666 (Purchase Agreement) between The Boeing Company (Boeing) and China Southern Airlines Company Limited (Customer) with

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. 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. Therefore Boeing agrees all advance payments due on or before the effective date of the signing of the Purchase Agreement, as specified in Articles 4.2 and 4.3, may be deferred without
interest until [*CTR], by which time Customer will pay all advance payments specified in the Purchase Agreement as being due on or before that date. 
 2.
Other Scheduled Advance Payments. 
 As defined in Article 4.2 of the Purchase Agreement, advance payments are required for each
Aircraft in the percentages and at the times shown in Table 1 of the Purchase Agreement. For all advance payments due to Boeing, Boeing will provide Customer with an invoice [*CTR] prior to the date the advance payment is due. This is done as an
accommodation for Customer and does not relieve Customer from providing advance payments to Boeing at the times shown in Table 1 of the Purchase Agreement. 

3. Payment at Aircraft Delivery.

 Pursuant to Article 4.4 of the
Purchase Agreement, Customer will pay, or cause to be paid, the balance of the Aircraft Price of each Aircraft at delivery. Boeing will provide the invoice for such payment about [*CTR] days prior to Aircraft delivery. 

4. Rescheduling of Aircraft. 
 Concerning
Letter Agreement [*CTR] [*CTR], if Customer does not make all advance payments as specified in the Purchase Agreement, Boeing may reschedule any or all of the Aircraft at any time thereafter as it deems necessary based on Boeing’s production
considerations and constraints. Boeing will give Customer [*CTR] advance notice of any such Aircraft rescheduling, and will not reschedule such Aircraft if advance payments on all Aircraft are current prior to the expiration of such [*CTR] day
notification period. Boeing will work with Customer in good faith to explore alternatives to such Aircraft rescheduling as may be available. 
 5. Effect
of Aircraft Rescheduling. 
 If Boeing reschedules any or all of the Aircraft pursuant to the provisions of Paragraph 4 above, then
Customer and Boeing will complete a Supplemental Agreement to document the revised Aircraft delivery schedules within [*CTR] advance notice is given. 
 6.
Assignment. 
 Notwithstanding any other provisions of the Purchase Agreement, the rights and obligations described in this Letter
Agreement are provided to Customer in consideration of Customer becoming the operator of the Aircraft and cannot be assigned in whole or, in part. 
 7.
Confidential Treatment. 
 The information contained herein represents confidential business information and has value precisely
because it is not available generally or to other parties. Customer will limit the disclosure of its contents, except for as required by applicable laws or regulations, to employees of Customer with a need to know the contents for purposes of
helping Customer perform its obligations under the Purchase Agreement and who understand they are not to disclose its contents to any other person or entity without the prior written consent of Boeing.

	Subject:	Clarifications and Understandings 

  

	Reference:	 Purchase Agreement No. PA-04666 (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 777-300ER 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 Customer 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.

 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. 
 Agreement 

1. 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.
