	5.	Deferral Charges on Deferred Advance Payments: 

 The foregoing reduced advance payment schedules
constitute a deferral of certain amounts due Boeing pursuant to the advance payment schedule as set forth in Table 1-1, Table 1-2, and Table 1-3 of the Purchase Agreement. Accordingly, if Customer chooses to utilize the reduced advance payment schedules(s), Customer shall pay deferral charges to Boeing on all such deferred amounts of the advance payments
for the Aircraft. 
 Deferral charges on all deferred advance payment amounts will be calculated on the basis of the LIBOR rate as published in the Wall
Street Journal, U. S. Edition, effective on the date of Purchase Agreement execution, and reset periodically as the LIBOR rate fluctuates, plus one percent (1.0%). This deferral charge will be calculated on a 365/366 day year. 

Deferral charge payments will be due from Customer to Boeing on the first business day of each calendar quarter, for the previous calendar quarter, and will
be computed on the basis of the actual number of elapsed days for the period commencing on the date such deferred amounts would have been due and terminating on the date of delivery of the designated Aircraft. 

Further to the above, following the calculation method stated above, all such calendar quarter deferral charge payments may be further deferred such that all
deferral charge payments for each of the Aircraft will be made at the time of each such Aircraft delivery. 
  

	6.	Re-Scheduling of Aircraft: 

 In the event of a re-schedule, to a later delivery position, of any of the Aircraft under the terms of the Agreement, Boeing will recalculate the amount of advance payments and deferral charges due from Customer under the above
described deferred Advance Payment Schedule after giving effect to such re-scheduling and, without interest, refund to Customer within 5 business days any amounts held by Boeing in excess of such recalculated
amounts. 
 In the event of a re-schedule, to an earlier delivery position, of any of the Aircraft under the terms
of the Agreement, Boeing will recalculate the amount of advance payments due from Customer under the above described deferred Advance Payment Schedule after giving effect to such re-scheduling and Customer
will make immediate payment to Boeing of any amounts due within 5 business days, without any additional interest or other charges, as a result of such recalculated amounts applicable to such accelerated delivery position. 

 

	7.	Set-Off Rights 

 Customer agrees that in the
event of a default of its obligations under any purchase agreement with Boeing or any agreement with any Boeing subsidiary or affiliate, Boeing may apply any or all advance payments, or other payments made by Customer with respect to an aircraft or
any other Boeing product to cure, in part or in whole, any default with respect to any other aircraft or Boeing product or with respect to any other

obligation under any such Boeing purchase agreement or any such agreement with another Boeing subsidiary or affiliate. In the event that Boeing sets off against, or otherwise exercises rights
against any such payments made by Customer, and applies any such amounts to any obligations owed by Customer to Boeing, its subsidiaries or affiliates, Boeing will be entitled, after such application, to require Customer to replace within ten days
the amount so applied such that the total amount of advance payments would be restored to the aggregate total amount of advance payments due and owing under the Purchase Agreement as of the date of application of such amounts. 

 

	8.	Confidential Treatment: 

 Customer understands that certain commercial and financial
information contained in this Letter Agreement is considered by Boeing as confidential and, except as may otherwise be provided herein, will not, without the prior written consent of Boeing, disclose this Letter Agreement or any information
contained herein to any other person or entity except to employees and legal counsel of Customer with a need to know the contents for purposes of helping Customer negotiate, perform and/or enforce this Letter Agreement and/or 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. Notwithstanding the foregoing, in the event Customer seeks to enforce this Letter Agreement or the Purchase Agreement
by legal proceeding or becomes involved in any legal proceeding or arbitration with respect to this Letter Agreement or Purchase Agreement or is otherwise legally compelled by deposition, interrogatory, subpoena, governmental investigation or other
similar process, Customer may disclose the contents hereof or of the Purchase Agreement after providing notice to Boeing, unless otherwise prohibited by an order from any governmental authority or by mandatory provisions of applicable law. If
Customer is required by applicable law to file this Letter Agreement, or any information contained therein, with any governmental or regulatory agency, or receives a request or demand for this Letter Agreement, or any information contained therein,
from any government regulatory agency or court having jurisdiction over Customer, Customer shall, upon making its decision to so file or upon receipt of the request or demand, (a) notify Boeing of such decision, request or demand and
(b) notify any requesting party that this Letter Agreement is subject to this confidentiality clause. Nothing herein shall prevent Boeing from requesting the governmental regulatory agency or requesting the court for a protective order or other

 Revision: E 

Offerable Seat Product List for 787 Passenger Seats 
 Valid
through 15-SEP-2017 
 Instructions 

This Memo consists of two sections; the current Boeing Qualified Supplier List and the Customer Specific Offerable Seat Product List. 

In order to support an airline’s contractual supplier selection dates, the Boeing Contracts Regional Director requests the Customer-Specific Offerable
Passenger Seat Products List after the details for customer’s unique program are established. The Customer-Specific Offerable Passenger Seat Products List is developed based on considerations such as the customer’s unique
program particulars — including airplane schedules, delivery stream, and configuration complexities — in conjunction with an assessment of each seat supplier’s performance, capacity, and capability. Certain seat products may be deemed
not offerable or offerable with constraints based on this review, subject to Project Based Offerability. 
 Boeing reserves the right to limit,
change, or modify the Qualified Supplier List and Customer-Specific Offerable Passenger Seat Product List when required. Current release supersedes all prior revisions. 

For additional information, please contact your 787 Customer Engineering Account Manager. 

Changes to delivery stream, aircraft quantity, or supplier performance might require a re-evaluation
— and potential modification — of suppliers and seat products included in this list. 
 This document contains supplier
competitive sensitive information. In order to maintain the integrity of the data, Seat Procurement Management requests that security precautions be taken when sharing this information with Customers and/or internal Boeing personnel. This document
is intended only for Boeing employees and non-Boeing persons with authorized access. Use and distribution of this document and its contents is subject to PRO-2227,
“Information Protection,” and PRO-3439, “Release of Information Outside The Boeing Company,” as well as other applicable company, contractual, and government restrictions.

Subject to the limitations described in Article 10, within ninety (90) days after receiving Customer’s report pursuant to Article 7 for each Reporting Period, Boeing will use the data provided by the Customer in such report and the
methodology in Attachment B to calculate the Cumulative Actual Maintenance Costs for the Covered Aircraft as of the end of such Reporting Period and will provide to Customer a report comparing Actual Maintenance Costs versus Target Maintenance
Costs. 
 8.2 If the data determined pursuant to Article 8.1 indicates that the performance of the Covered Aircraft for the applicable

	9.	Corrective Action. 

 9.1 Should corrective action pursuant to Article 8.3 be required:

 9.1.1 Boeing will investigate the circumstances and possible causes of the Noncompliance; 

9.1.2 Boeing will provide technical assistance to Customer in the form of analysis and recommendations for reducing Actual Maintenance Cost;

 9.1.3 Boeing will, if necessary, initiate a design review of the Covered Aircraft systems, accessories, equipment or parts determined by
Boeing to be the primary cause of the Noncompliance and, when in Boeing’s judgment and soliciting input from airlines a redesign is indicated as a technically and economically practicable means of complying with the Program Commitment, Boeing
will initiate a redesign or cause the redesign of such items within 120 days; and 
 9.1.3.1 if such redesign results in retrofit kits
being offered by Boeing or Boeing’s suppliers, Boeing will provide such kits or cause such kits to be provided at no charge to Customer. Boeing will also reimburse at Boeing’s then -current warranty labor rate Customer’s reasonable
Direct Labor Costs for incorporation of any such kit manufactured to Boeing’s or Boeing’s supplier’s detailed design. Such reimbursement will be provided pursuant to Exhibit C, “Product Assurance Document,” of the AGTA. 

9.1.4 If, at the end of the Program, the Cumulative Actual Maintenance Cost for all Reporting Periods is greater than the Cumulative Target
Maintenance Cost for all Reporting Periods, Boeing will determine the difference between these two numbers (Excess Cost per Flight Hour) and within ninety (90) days after such determination, Boeing will pay to Customer an amount
equal to the Excess Cost per Flight Hour multiplied by the sum of the Fleet Flight Hours for all Reporting Periods not to exceed the [**] per Covered Aircraft, except for Reporting Periods where Customer has failed to report Actual Maintenance Cost
pursuant to Article 7if necessary, initiate a design review of the systems, accessories, equipment or parts determined by Boeing to be the primary cause of the Noncompliance and, when in Boeing’s judgment a redesign is indicated as a
technically and economically practicable means of complying with the Program Commitment, Boeing will redesign or cause the redesign of such items; and

 9.2 At Boeing’s request, Customer will assign to Boeing, any of Customer’s rights
against the manufacturer of any equipment, accessory or part installed in the Covered Aircraft as Boeing may reasonably require to fulfill its obligations with respect to any corrective action provided by Boeing herein. 

 

	10.	Conditions and Limitations. 

 10.1 If, with the intent of reducing the cost of Covered
Maintenance, Boeing or any supplier issues service bulletins, service letters or other written instructions or offers no-charge retrofit kits, Customer and its subcontractors will comply with such instructions
or install such kits (Comply) [**] after issuance of such instructions or shipment of such kits to Customer’s facility, or such longer period as may be mutually agreed by the parties (Response Period). If Customer or any of
its subcontractors does not Comply within the Response Period, then after expiration of such Response Period all maintenance costs which Boeing determines would have been eliminated if such instructions or kits had been incorporated will be
subtracted from the Actual Maintenance Costs reported. 
 10.2 Customer will promptly notify Boeing in writing of any variations in its
maintenance cost accounting system or procedures or those of its subcontractors which would affect the proper reporting of Actual Maintenance Costs. Boeing will make adjustments to the Cumulative Target Maintenance Cost to reflect the effect of any
such variations. 
 10.3 Upon reasonable notice to Customer, Boeing will have the right to audit all Actual Maintenance Cost Data reported
by Customer during the Program Term as well as the maintenance practices and procedures related thereto. Customer will also obtain from its subcontractors permission for Boeing to audit from time to time and upon reasonable notice such
subcontractors’ maintenance records and practices during the Program as they pertain to the Covered Aircraft. Boeing will have the right to disapprove costs it deems improperly reported or lacks sufficient data to verify either the Direct Labor
Hours performed or the Direct Material Costs incurred in performing such maintenance. Boeing will provide Customer written notification of its disapproval of any such costs, and, if Customer does not provide proof [**] after such notification that
such costs are properly chargeable, Boeing’s disapproval will be deemed final and conclusive and Boeing will deduct such costs from the computation of Actual Maintenance Costs. 

10.4 [**] to Customer, Boeing may inspect Customer’s maintenance facilities, programs and procedures. If Boeing recommends in writing
reasonable changes to Customer’s or its subcontractors’ maintenance programs and procedures which would reduce Actual Maintenance Costs and Customer or its subcontractors do not implement such changes or delay implementing such changes
beyond the Response Period set forth in Article 10.1, Boeing will adjust the Actual Maintenance Costs that have been reported to deduct the increased maintenance costs which Boeing estimates resulted from the failure or delay in implementing such
changes.

 Attachment B: Adjustments 

Boeing will adjust as described in this Attachment B the Maintenance Cost Benchmark Data submitted, the Target Maintenance Costs reported and Actual
Maintenance Cost Data reported. 
  

	1.	Currency Exchange Rate. 

 Boeing will convert maintenance cost data submitted in the Customer’s
currency to U.S. Dollars by multiplying such reported costs by the applicable exchange rate published in the U.S. edition of the Wall Street Journal on the day (not including weekends or U.S. national holidays) nearest to the midpoint of the
applicable Reporting Period. 
  

	2.	Escalation Indices. 

  

	 	2.1	Material Price Inflation. [**]. 

  

	 	2.2	Labor Price Inflation. The measure of labor price inflation will be the “Employment Cost Index for workers in aircraft manufacturing - Wages and Salaries” (ECI code 3721) obtained from the
publication published quarterly by the U.S. Department of Labor, Bureau of Labor Statistics or any comparable successor publication published by the U.S. Department of Labor Bureau of Labor Statistics or any comparable successor agency (Labor
Index). As the Labor Index values are only released on a quarterly basis, the value released for the month of March will be used for the months of January and February; the value for the month of June will be used for the months of April and
May; the value for the month of September will be used for the months of July and August; and the value for the month of December will be used for the months of October and November. 


 

	3.	Benchmark Method for Determining Target Maintenance Costs. 

 The Target Maintenance Costs will be
determined for the Covered Aircraft by adjusting Customer’s Maintenance Cost Benchmark Data as follows:

		 	BOEING PROPRIETARY	 	









 Attachment B: Adjustments (continued) 

3.1 The Direct Material Costs reported in the Maintenance Cost Benchmark Data will be revised to values expressed in base year 2016 (Base
Year) by multiplying such costs by the ratio of the average of the values for the Material Index published during the twelve months of the Base Year to the average of the values for the Material Index published for the months in which
such Direct Material Costs were incurred. 
 3.2 The Direct Labor Costs reported in the Maintenance Cost Benchmark Data will be revised to
values expressed in the Base Year by multiplying such costs by the ratio of the average of the values for the Labor Index published during the twelve (12) months of the Base Year to the average of the values for the Labor Index published [**].

 3.3 Furthermore, Boeing will use the operational assumptions provided by Customer to recalibrate the Maintenance Cost Benchmark Data to
determine the Target Maintenance Cost. In determining the Target Maintenance Cost, Boeing may adjust the Maintenance Cost Benchmark Data for various operational assumptions reported to Boeing, including but not limited to: 

 

	 	(i)	flight time; 

  

	 	(ii)	annual utilization; 

  

	 	(iii)	labor assumptions; and 

  

	 	(iv)	aircraft age. 

 3.4 Boeing will then increase the Benchmark Fleet Value by the Relative
Difference to determine the Equivalent Maintenance Cost for the Covered Aircraft.

 Attachment B: Adjustments (continued) 

 

	4.	Reporting Period Adjustments. 

 4.1 The reported Direct Material Cost for a Reporting
Period and the reported Subcontracted Maintenance Material Cost for a Reporting Period will be revised to values expressed in the Base Year by multiplying such costs by the ratio of the average of the values of the Material Index published for the
twelve months of the Base Year to the average of the values for the Material Index published during twelve months of the applicable Reporting Period. 

4.2 The reported Direct Labor Cost for a Reporting Period and the reported Subcontracted Maintenance Labor Cost for a Reporting Period will be
revised (i) by multiplying the reported Direct Labor Cost by the ratio of the Labor Rate specified in the operational assumptions to the Customer’s then-current Labor Rate and (ii) by multiplying the reported Subcontracted Maintenance
Labor Cost by the ratio of the Subcontracted Maintenance Labor Rate specified in the operational assumptions to the Subcontracted Maintenance Labor Rate as reported. 
  

	 	4.3	Recalculation of Target Maintenance Cost. 

 4.3.1 Covered Aircraft. The Target
Maintenance Cost is based on the number of Covered Aircraft. If the number of Covered Aircraft changes during any Reporting Period, the Target Maintenance Cost will be recalculated for that Reporting Period to address any change to the average fleet
age. 
 4.3.2 Delivery Schedule. The Target Maintenance Cost is based on the delivery schedule of Covered Aircraft as described in
Table 1 of the Purchase Agreement. If the delivery schedule for the Covered Aircraft changes during any Reporting Period, the Target Maintenance Cost will be recalculated for that Reporting Period and subsequent Reporting Periods to address any
resulting changes to the average fleet age. 
 4.3.3 Furthermore, if Customer updates any operational assumptions, Boeing may adjust the
Target Maintenance Cost as appropriate. For example, Boeing may adjust for assumptions such as: 
  

	 	(i)	flight time; 

  

	 	(ii)	annual utilization; 

  

	 	(iii)	labor assumptions; and 

  

	 	(iv)	aircraft age. 

 4.3.4 Boeing will provide Customer any recalculated Target Maintenance Costs
for the applicable Reporting Period.
