The obligations set forth in this Agreement are in addition to the obligations set forth in the GTA. In the event of conflict between the terms of this Agreement and the terms of the GTA, the terms of this Agreement shall take precedence. Terms which are capitalized but not otherwise defined herein shall have the meaning given to them in Article I of the GTA.

Confidentiality of Information. This Agreement contains information specifically for Airline and GE, and nothing herein contained shall be divulged by Airline or GE to any third person, firm or corporation, without the prior written consent of the other Parties, which consent shall not be unreasonably withheld; except (i) that Airline’s consent shall not be required for disclosure by GE of this Agreements, to an Engine program participant, joint venture participant, engineering service provider or consultant to GE so as to enable GE to perform its obligations under this Agreement or to provide informational data; (ii) to the extent required by Government agencies, by law, or to enforce this Letter Agreement; and (iii) to the extent necessary for disclosure to the Parties’ respective insurers, accountants or other professional advisors who must likewise agree to be bound by the provisions of this paragraph.

CONDITIONS FOR SPECIAL ALLOWANCES/DELAY/CANCELLATION

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.

[***]

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

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.

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.

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.

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).
