	I.	The base price for Products purchased hereunder shall be adjusted pursuant to the provisions of this Exhibit. 

  

	II.	For the purpose of this adjustment: 

  

	 	A.	Base price shall be the price(s) set forth on the Purchase Order as acknowledged by CFM, 

  

	 	B.	The Composite Price Index (CPI) shall be calculated, to the second decimal place, using the following formula: 

***** 
 Where: 

*****

	 	C.	Each CPI shall be determined to the second decimal place. Calculation shall be to the third decimal digit and if the third decimal digit is five or more, the second decimal digit shall be raised to the next higher
figure. If the third decimal digit is less than five, the second decimal figure shall remain as calculated. 

  

	 	D.	The Base Composite Index (*****) shall be the base index stated in the published prices.

	IV.	The invoice price shall be the final price and will not be subject to further adjustments in the indices. In no event shall the invoice price be lower than the base price.

less than five, the third decimal figure shall remain as calculated. If the calculation of this ratio results in a number less than 1.000, the ratio will be adjusted to 1.000. The resulting three digit decimal shall be used to calculate *****.

  
 *****Confidential portions of the
material have been omitted and filed separately with the Securities and Exchange Commission.

	VI.	Values to be utilized in the event of unavailability. If at the time of delivery of Product, CFMI is unable to determine the adjusted price because the applicable values to be used to determine the *****
have not been released by the Bureau of Labor Statistics, then: 

  

	 	a)	The Price Adjustment, to be used at the time of delivery of the Product, will be determined by utilizing the escalation provisions set forth above. The values released by the Bureau of Labor Statistics and available
***** prior to scheduled Product delivery month 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 Product Price Adjustment. If no value has
been released for an applicable month, the provisions set forth in Paragraph b, below, will apply. If prior to delivery of a Product, the U.S. Department of Labor changes the base year for determination of the ***** values as defined above, such
rebase values will be incorporated in the Price Adjustment calculation. 

  

	 	b)	If prior to delivery of a Product, U.S. Department of Labor 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 Price Adjustment, CFMI will, prior to delivery of any such Product, select a substitute for such values from data
published by the Bureau of Labor Statistics or other similar data reported by non-governmental United States organizations, such substitute to lead in application to the same adjustment result insofar as possible, as would have been achieved by
continuing the use of the original values as they may have fluctuated during the applicable time period. Appropriate revisions of the formula will be made as required to reflect any substitute values. However, if within ***** from delivery of the
Product, the Bureau of Labor Statistics should resume releasing values for the months needed to determine the Product Price Adjustment, such values will be used to determine any increase or decrease in the Product Price Adjustment from that
determined at the time of delivery of such Product. 

  

	 	c)	In the event escalation provisions are made non-enforceable or otherwise rendered null and void by any agency of the United States Government, the parties agree, to the extent they may lawfully do so, to equitably
adjust the base price of any affected Product to reflect an allowance for increase or decrease in labor compensation and material costs occurring since February of the base price year which is consistent with the applicable provisions of this Price
Escalation formula. 

  

	 	d)	For the calculation herein, the values released by the Bureau of Labor Statistics and available to CFMI at the end of the month prior to scheduled Product delivery month will be used to determine the ***** values for
the applicable months (including those noted as preliminary by the Bureau of Labor Statistics) to 

  
 *****Confidential portions of the
material have been omitted and filed separately with the Securities and Exchange Commission. 
 9 

	 	e)	calculate the Product Price Adjustment for the Product invoice at the time of delivery. The values will be considered final and no Product Price Adjustment will be made after Product delivery for any subsequent changes
in published index values. 

  

	Note:	Any rounding of a number, with respect to escalation of the Product Price, will be accomplished as follows: If the first digit of the portion to be dropped from the number is five or greater, the preceding digit will be
raised to the next higher number.

	2.	Allowance Not Paid 

 Allowances described in this Letter Agreement No. 2 will
not be earned or paid with respect to Engines which have been delivered to the aircraft manufacturer for installation in Airline’s Aircraft if, thereafter, for any reason, Airline’s purchase order with the aircraft manufacturer is
terminated, canceled or revoked, or if delivery of the Aircraft will be prevented or delayed beyond the expiration of the Delivery Period. 
  

	3.	Adjustment of Allowances 

 The special allowance described in paragraph II of this
Letter Agreement No. 2 is contingent upon Airline purchasing and accepting delivery of a minimum of ***** CFM56-5B8/P powered A318 Aircraft, ***** Additional A319 Aircraft powered by CFM56-5B5/P and ***** spare CFM56-5B Engine (“Minimum
Number”) for delivery during the Delivery Period. If Airline has canceled or otherwise failed to accept delivery of one or more of the required Minimum Number within the Delivery Period, the allowances will be adjusted as follows: 

***** 
 Adjustment of allowances in
accordance with the above formula may be made by CFMI prospectively to take into account Aircraft or Spare Engine delays, and/or cancellations. In any case, Airline agrees to promptly reimburse CFMI for any allowance overpayments determined to have
been made at the application of the adjustment formula set forth above *****. Unless otherwise agreed by CFMI, no allowance shall be paid on Aircraft not accepted within the Delivery Period and such Aircraft shall not be counted for purposes of the
adjustment formula set forth above. 
  

	4.	Assignability of Allowance

	6.	Cancellation of Engines 

 Airline recognizes that harm or damage will be sustained
by CFMI if Airline places a purchase order for spare Engine(s) or for Aircraft (the ***** firm Aircraft) equipped with installed Engines and subsequently cancels such purchase order (and such cancellation is not caused by acts (or failure to act) of
Airbus or CFMI or otherwise fails to accept delivery of the Engines or Aircraft when duly tendered. Within ***** of any such cancellation or if failure to accept delivery occurs, Airline shall remit to CFMI, as liquidated damages, a cancellation
charge equal to ***** of the Engine price, determined as of the date of scheduled Engine delivery to Airline or to the aircraft manufacturer, whichever is applicable.

for a period, or cumulative period, of more than *****, such delay shall be considered a cancellation and the applicable provisions hereof regarding the effect of cancellation shall apply.

Agreement No. 3 applies only to the new Additional 319 Aircraft and A320 Aircraft described in this Letter Agreement No. 3 (together or individually the “Aircraft”) equipped with new
CFM56-5B engines (together or individually the “Engines”) purchased by Airline directly from the aircraft manufacturer. 

 

	2.	Allowance Not Paid

not be earned or paid with respect to Engines which have been delivered to the aircraft manufacturer for installation in Airline’s Aircraft if, thereafter, for any reason, Airline’s purchase order with the aircraft manufacturer is

	3.	Adjustment of Allowances 

 The special allowance described in paragraph II of this
Letter Agreement No. 3 is contingent upon Airline purchasing and accepting delivery of a minimum of ***** Additional A319 Aircraft or Additional A320 Aircraft (as described in this Letter Agreement No. 3),) and purchasing and taking
delivery from CFMI ***** spare CFM56-5B engines (“Minimum Number”) for delivery during the Delivery Period. If Airline has canceled or otherwise failed to accept delivery of one or more of the
