CONDITIONS FOR SPECIAL ALLOWANCES/DELAY/CANCELLATION

1. Termination of Special Allowances

For the avoidance of doubt, it is understood that GE shall have no further obligation beyond the Expiration Date to provide any of such Special Allowances which were not provided to Airline, through no fault of GE.

2. Adjustment of Allowances

[***]

3. Assignability of Allowance

Any allowance described herein is exclusively for the benefit of Airline and is not assignable without GE’s written consent.

4. Set Off for Outstanding Balance

GE shall be entitled, with five (5) days prior written notice, to set off any outstanding obligation and amounts that are due and owing from Airline to GE (and not subject to a good faith dispute) for goods or services (whether or not in connection with this Letter Agreement and/or GTA), against any amount payable by GE to Airline in connection with this Letter Agreement and/or GTA.

5. Cancellation Spare Engines

Airline recognizes that harm or damage will be sustained by GE if Airline fails to accept delivery of the Spare Engines when duly tendered. Within thirty (30) days of any such cancellation or failure to accept delivery occurs, Airline shall remit to GE a minimum cancellation charge equal to [***] of the Engine price, determined as of the date of scheduled Engine delivery to Airline. Further GE reserves the right to terminate this agreement, in part or in whole, if the PDP Payment is not paid in accordance with the schedule in Exhibit A.

The parties acknowledge such minimum cancellation charge to be a reasonable estimate of the minimum harm or damage to GE in such circumstances. If any such cancellation or failure occurs with less than such twelve (12) months prior written notice, GE shall also retain all remedies in law and equity available to GE for damages in excess of such minimum cancellation charge.

GE shall retain any progress payments or other deposits made to GE for any such Engine. Such progress payments will be applied first to the minimum cancellation charge for such Engine and, in circumstances described in the last sentence of the preceding paragraph, then to any further damages sustained by GE as a result of such cancellation or failure to accept delivery. Progress payments held by GE in respect of any such Engine which are in excess of such

LA13-1

GE PROPRIETARY INFORMATION

amounts will be refunded to Airline, provided Airline is not then in arrears on other amounts owed to GE.

6. Delay Charge for Spare Engines

In the event Airline delays the scheduled delivery date of a Spare Engine 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.

7. Offset Requirements

Any allowance described herein is predicated on the assumption that no offset or countertrade requirement will be imposed on GE. If such requirement is imposed, then GE reserves the right to reduce the allowance commensurate with the cost to GE of performing such offset or countertrade obligation(s).

ESCALATION

I. The base value for the guarantees and other prices expressed in applicable U.S. base year dollars are subject to escalation and shall be adjusted effective January 1st of the year following the applicable base year and January 1st of each calendar year thereafter pursuant to the provisions of this Attachment D.

II. The following three average indices as published in December of the year prior to the applicable guarantee or price year shall be used to determine the amount of adjustment upward or downward:

A. The four quarter average discussed below of the "ECI 336411W" or "NAICS Code 336411" (BLS code: CIU2023211000000I)," as published by the U.S. Department of Labor, Bureau of Labor Statistics, to the second decimal place.

B. The twelve-month average discussed below of the wholesale price index for "Industrial Commodities," Codes 03 through 15 (BLS code: wpu03thru15), as published by the Bureau of Labor Statistics, to the second decimal place.

C. The twelve-month average discussed below of the wholesale price index for "Metals and Metal Products," Code 10 (BLS code:  wpu10), as published by the Bureau of Labor Statistics,  to the second decimal place.

III. The index described in Paragraph II.A above is published on a quarterly basis and the indices described in Paragraphs II.B and II.C above are published on a monthly basis. The four quarter average for the index described in Paragraph II.A above and the twelve month average for each index described in Paragraphs II.B and II.C above shall be determined for the base and current years. The base year shall be the twelve months ended September for the year preceding the base year as defined in the relevant section of this Agreement. The current year shall be the twelve months ended September of the year preceding the year in which the guarantee, rate, or price applies. Following is the methodology which shall be used to calculate the average indices described in Paragraphs II.A, II.B, and II.C for a particular twelve-month period with respect to the base year or relevant current year (the "Calculation Twelve Month Period"):

A. The "four quarter average" described in Paragraph II.A above shall be determined by averaging the index for each of the four quarters contained within the Calculation Twelve Month Period.

B. The "twelve-month average" described in Paragraphs II.B and II.C above shall be

LA13-1

GE PROPRIETARY INFORMATION

determined by averaging the index for each of the twelve months contained within the Calculation Twelve Month Period.

IV. Values for guarantees and prices in any calendar year subject to this clause shall be adjusted by the average of the percentage change in each average index described above for the current over the base year.

Example - determine base price or guarantee rate for 2007 with a base year of 2006:

Escalation IndicesWeighting		Base Indices	Current Indices	Percent Changes	Weighted
1. Labor	33.3%	97.95	101.80	3.93%	1.31%
2. Metals	33.3%	159.18	165.81	4.17%	1.39%
3.  Industrial Commodities	33.3%	156.18	169.25	8.37 %	2.79%

Total Escalation 5.5%

Assume a base price or guarantee rate in 2006 $ of 100.

Calculate 2007 price or guarantee rate= $100 X [1.055] = $105.50.

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

VI. In determining the adjustment to be added to the guarantee rate or price, the total escalation percent increase shall be calculated to the nearest one-tenth of one percent.  If the next succeeding decimal place is five or more, the preceding decimal figure shall be raised to the next higher figure. If the next succeeding decimal place is four or less, the preceding decimal figure shall be kept  at its then current figure.

VII. In the event that the indices specified herein are discontinued, or the basis of their calculation is modified, equivalent indices shall be substituted by GE to reflect increases in labor and material costs up to the September of the year prior to scheduled delivery of the Products.

VIII. In the event the U.S. Bureau of Labor Statistics publishes indexes using a new base year, then the escalation shall be computed using such new indices.
