LEASING OF SPARE PARTS 12.1 Applicable Terms The terms and conditions of this Paragraph 12 will apply to the Lease of Seller Parts listed in Appendix "A" to this Paragraph 12 ("Leased Parts") and will form a part of each lease of any Leased Part by the Buyers from the Seller after the date hereof. Except for the description of the Leased Part, the Lease Term, the Leased Part delivery and return locations and the Lease Charges (defined below in Paragraph 12.4), all other terms and conditions appearing on any order form or other document pertaining to Leased Parts will be deemed inapplicable, and in lieu thereof the terms and conditions of this Paragraph 12 will prevail. For purposes of this Paragraph 12, the term "Lessor" refers to the Seller and the term "Lessees" refers to the Buyers. Parts not included in Appendix "A" to this Paragraph 12 may be supplied under a separate lease agreement between the Seller and the Buyers. LA1-23 *** Confidential Treatment Requested AWE/USA-A350 PRIVILEGED AND CONFIDENTIAL <PAGE> 12.2 Lease Procedure: Spare Parts Leased At the Lessees' request by telephone (to be confirmed promptly in writing), facsimile, letter or other written instrument, the Lessor will lease Leased Parts, which will be made available in accordance with Paragraph 4.2.3, to the Lessees as substitutes for parts withdrawn from an Aircraft for repair or overhaul. Each lease of Leased Parts will be evidenced by a lease document ("Lease") issued by the Lessor to the Lessees no later than seven (7) business days after delivery of the Leased Part. 12.3 Lease Term: Return The term of the lease ("Lease Term") will commence on the date of dispatch of the Leased Part to the Lessees or its agent at the Lessor's facility and will end on the date of receipt at the Lessor's facility of the Leased Part or in a serviceable condition. The Lease Term will not exceed thirty (30) days after such date of dispatch, unless extended by written agreement between Lessor and Lessees within such thirty (30)-day period (such extension not to exceed an additional thirty (30) days). Notwithstanding the foregoing, the Lease Term will end in the event, and upon the date, of exercise of the Lessees' option to either purchase or exchange the Leased Part, as provided herein. 12.4 Lease Charges and Taxes The Lessees will pay the Lessor (a) a daily rental charge for the Lease Term in respect of each Leased Part equal to one-three-hundred-sixty-fifth (1/365) of the Catalog Price of such Leased Part, as set forth in the Seller's Spare Parts Price List in effect on the date of commencement of the Lease Term, (b) any reasonable additional costs which may be incurred by the Lessor as a direct result of such Lease, such as inspection, test, repair, overhaul and repackaging costs as required to place the Leased Part in satisfactory condition for lease to a subsequent customer, (c) all transportation and insurance charges and (d) any taxes, charges or customs duties imposed upon the Lessor or its property as a result of the lease, sale, delivery, storage or transfer of any Leased Part (the "Lease Charges"). All payments due hereunder will be made in accordance with Paragraph 6. In the event that the Leased Part has not been returned to the Lessor's designated facilities by the last day of the Lease Term, the Lessor will be entitled, in addition to any other remedy it may have at law or under this Paragraph 12, to charge to the Lessees, and the Lessees will pay, all of the charges referred to in this Paragraph 12.4 accruing for each day after the end of the Lease Term and for as long as such Leased Part is not returned to the Lessor and as though the Lease Term were extended to the LA1-24 AWE/USA-A350 PRIVILEGED AND CONFIDENTIAL <PAGE> period of such delay. Should the Lessees fail to return the Leased Part of the Lessor at the end of the lease Term, such failure will be deemed to be an election by the Lessees to purchase the Leased Part and the Lessees will pay the price set forth in Paragraph 12.8. 12.5 Title Title to each Leased Part will remain with the Lessor at all times unless the Lessees exercises its option to purchase it in accordance with Paragraph 12.8 of this Letter Agreement, in which case title will pass to the Lessees in accordance with Paragraph 7 of this Letter Agreement. 12.6 Risk of Loss Except for normal wear and tear, each Leased Part will be returned to the Lessor in the same condition as when delivered to the Lessees. However, the Lessees will not without the Lessors' prior written consent repair, modify or alter any Leased Part. Risk of loss or damage to each Leased Part will remain with the Lessees until such Leased Part is redelivered to the Lessor at the return location specified in the applicable Lease. If a Leased Part is lost or damaged beyond repair, the Lessees will be deemed to have exercised its option to purchase the part in accordance with Paragraph 12.8, as of the date of such loss or damage. 12.7 Record of Flight Hours All flight hours accumulated by the Lessees on each Leased Part during the Lease Term will be documented by the Lessees. Records will be delivered to the Lessor upon return of such Leased Part to the Lessor include all documentation pertinent to inspection, maintenance and/or rework of the Leased Part and evidence of incidents such as hard landings of aircraft on which such Leased Part was installed from time to time during the Lease term, abnormalities of operation and corrective action taken by the Lessees as a result of such incidents. 12.8 Option to Purchase 12.8.1 Option to Purchase The Lessees may at its option, exercisable by written notice given to the Lessor, elect during or at the end of the Lease Term to purchase each Leased Part, in which case the then current purchase price for such Leased Part as set forth in the Seller's Spare LA1-25 AWE/USA-A350 PRIVILEGED AND CONFIDENTIAL <PAGE> Parts Price List will be paid by the Lessees to the Lessor. The immediately preceding sentence will apply to new Leased Parts only. In the event the Leased Part is used, [...***...] of the then current purchase price for such Leased Part will be paid by the Lessees to the Lessor. Such option will be contingent upon the Lessees' providing the Lessor with evidence satisfactory to the Lessor that the original part fitted to the Aircraft is beyond economical repair. [...***...] 12.8.2 In the event of purchase, the Leased Part will be warranted in accordance with Paragraph 11 as though such Leased Part were a Seller Part; provided, however, that (i) the Seller will prorate the full Seller Part Warranty Period granted to the Buyer according to the actual usage of such Leased Part and (ii) in no event will such Seller Part Warranty Period be less than six (6) months from the date of purchase of such Leased Part. A warranty granted under this Paragraph 12.8.2 will be in substitution for the warranty granted under Paragraph 12.9 at the commencement of the Lease Term. 12.9 Warranties on Leased Parts The Lessor, in its capacity as "Lessees," under its arrangements with the Manufacturer, in its capacity as "Lessor," has negotiated and obtained the following warranties from the Manufacturer with respect to the Leased Parts, subject to the terms, conditions, limitations and restrictions all as hereinafter set out. The Lessor hereby assigns to the Lessees, and the Lessee hereby accepts, all of the rights and obligations of the Lessor in its capacity as "Lessees" as aforesaid under the said warranties and the Lessor subrogates the Lessee as to all such rights and obligations in respect of Leased Parts during the Lease Term with respect thereto. The Lessor hereby warrants to the Lessees that it has all requisite authority to make the foregoing assignment and effect the foregoing subrogation to and in favor of the Lessees and that it will not enter into any amendment of the provisions so assigned or subrogated without the prior written consent of the Lessees. Capitalized terms utilized in the following provisions have the meanings assigned thereto in this Letter Agreement, except that the term "Lessor" refers to the Manufacturer and the term "Lessees" refers to the Lessor. LA1-26 ***Confidential Treatment Requested AWE/USA-A350 PRIVILEGED AND CONFIDENTIAL <PAGE> QUOTE 12.9.1 The Lessor warrants that each Leased Part will at the time of delivery thereof: (a) conform to the applicable specification for such part, (b) be free from defects in material, (c) be free from defects in workmanship, including without limitation processes of manufacture, and (d) be free from defects in design (including, without limitation, selection of materials) having regard to the state of the art at the date of such design. 12.9.2 Survival of Warranties With respect to each Leased Part, the warranty set forth above in Paragraph 12.9.1(a) will not survive delivery, and the warranties set forth above in Paragraphs 12.9.1(b), 12.9.1(c) and 12.9.1 (d) will survive delivery only upon the conditions and subject to the limitations set forth below in Paragraphs 12.9.3 through 12.9.8. 12.9.3 Warranty and Notice Periods The Lessees' remedy and the Lessor's obligation and liability under this Paragraph 12.9, with respect to each defect, are conditioned upon (i) the defect having become apparent to the Lessees within the Lease Term and (ii) the Lessor's warranty administrator having received written notice of the defect from the Lessees within [...***...] after the defect became apparent to the Lessees. 12.9.4 Return and Proof The Lessees' remedy and the Lessor's obligation and liability under this Paragraph 12.9, with respect to each defect, are also conditioned upon: (a) the return by the Lessees as soon as practicable to the return location specified in the applicable Lease, or such other place as may be mutually agreeable, of the Leased Part claimed to be defective, and (b) the submission by the Lessees to the Lessor's warranty administrator of reasonable proof that the claimed defect is due to a matter embraced within ***Confidential Treatment Requested LA1-27 AWE/USA-A350 PRIVILEGED AND CONFIDENTIAL <PAGE> the Lessor's warranty under this Paragraph 12.9 and that such defect did not result from any act or omission of the Lessees, including but not limited to any failure to operate or maintain the Leased Part claimed to be defective or the Aircraft in which it was installed in accordance with applicable governmental regulations and the Lessor's applicable written instructions. 12.9.5 Limitation of Warranty The Lessees' remedy and the Lessor's obligation and liability under this Paragraph 12.9 with respect to each defect are limited to the repair of such defect in the Leased Part in which the defect appears, or, as mutually agreed, to the replacement of such Leased Part with a similar part free from defect. Any replacement part furnished under this Paragraph 12.9.5 will for the purposes of this Letter Agreement be deemed to be the Leased Part so replaced. 12.9.6 Suspension and Transportation Costs 12.9.6.1 If a Leased Part is found to be defective and is covered by this warranty, the Lease Term and the Lessees' obligation to pay rental charges as provided in Paragraph 12.4(a) of this Letter Agreement will be suspended from the date on which the Lessees notify the Lessor of such defect until the date on which the Lessor has repaired, corrected or replaced the defective Leased Part, provided, however, that the Lessees have withdrawn such defective Leased Part from use, promptly after giving such notice to the Lessor. If the defective Leased Part is replaced, such replacement will be deemed to no longer be a Leased Part under the Lease as of the date on which such part was received by the Lessor at the return location specified in the applicable Lease. If a Leased Part is found to be defective on first use by the Lessees and is covered by this warranty, rental charges as provided in Paragraph 12.4(a) will not accrue and will not be payable by the Lessees until the date on which the Lessor has repaired, corrected or replaced the defective Leased Part. 12.9.6.2 All transportation and insurance costs associated with the return of the defective Leased Part to the Lessor and the return of the repaired, corrected or replacement part to the Lessees will be borne by the Lessor. LA1-28 AWE/USA-A350 PRIVILEGED AND CONFIDENTIAL <PAGE> 12.9.7 Wear and Tear Normal wear and tear and the need for regular maintenance and overhaul will not constitute a defect or nonconformance under this Paragraph 12.9. 12.9.8.

QUOTE 1. SCOPE 1.1 The Seller hereby provides the Buyers with the following maintenance cost guarantee (the "Maintenance Cost Guarantee"). 1.2 The Seller guarantees the maximum direct labor and material costs for parts and systems identified in Appendix 1 ("Parts and Systems"). The Maintenance Cost Guarantee applies to maintenance related to parts, subassemblies or assemblies that are scrapped in the process of maintaining, restoring or overhauling A350 Aircraft components categorized as "rotable" or "repairable" items, and does not include any indirect maintenance labor and material expenditures. 1.3 The Maintenance Cost Guarantee does not cover line maintenance or A checks, or any work related to either line maintenance or A checks (transit, daily and weekly checks and associated trouble-shooting and deferrals, etc.). 2. DURATION This Maintenance Cost Guarantee covers the [...***...] period commencing on Delivery of the first A350-800 Aircraft, for A350-800 Aircraft, or A350-900 Aircraft, for A350-900 Aircraft (the "Duration"). 3. GUARANTEED DIRECT MAINTENANCE COST 3.1 Direct maintenance costs ("DMCs") are those maintenance labor and material costs directly expended in performing maintenance on an item or aircraft. *** Confidential Treatment Requested AWE/USA -A350 LA9-2 PRIVILEGED AND CONFIDENTIAL <PAGE> DMCs do not include those indirect maintenance labor and material expenditures which contribute to the overall maintenance operations, line station servicing, administration, record keeping, supervision, tooling, test equipment, facilities, etc. (DMC definition source: ATA CSDD - Common Support Data Dictionary.) 3.2 The Seller guarantees for the Duration that the Direct Maintenance Cost per flying hour for the maintenance, restoration, and overhaul of the Parts and Systems (the "Guaranteed Direct Maintenance Cost") will not exceed an average of: (i) For the A350-800 Aircraft: (a) [...***...] per flight hour for the First Computation Period (as defined in Clause 6.2) (the "A350-800 First Guaranteed DMC"); or (b) [...***...] per flight hour for the Second Computation Period (as defined in Clause 6.3) (the "A350-800 Second Guaranteed DMC"). The A350-800 First Guaranteed DMC and the A350-800 Second Guaranteed DMC are together the "A350-800 Guaranteed DMCs." (ii) For the A350-900 Aircraft: (a) [...***...] per flight hour for the First Computation Period (as defined in Clause 6.2) (the "A350-900 First Guaranteed DMC"); or (b) [...***...] per flight hour for the Second Computation Period (as defined in Clause 6.3) (the "A350-900 Second Guaranteed DMC"). The A350-900 First Guaranteed DMC and the A350-900 Second Guaranteed DMC are together the "A350-900 Guaranteed DMCs". The A350-800 Guaranteed DMCs and the A350-900 Guaranteed DMCs are collectively the "Guaranteed DMCs." 3.3 The Guaranteed DMC values are expressed in January 2005 prices. These prices will be increased every year in accordance with the Direct Maintenance Cost Adjustment Formula set out in Appendix 3. 4. ADJUSTMENTS 4.1 The Guaranteed DMCs are based on the assumptions set out in Appendix 2 and an estimated A350 Aircraft average flight leg time of seven point zero (7.0) hours and an average usage rate of four thousand five hundred (4,500) flight hours per year per A350 Aircraft. Should *** Confidential Treatment Requested AWE/USA -A350 LA9-3 PRIVILEGED AND CONFIDENTIAL <PAGE> the applicable A350 Aircraft average flight leg time differ from seven point zero (7.0) hours, then adjustments will be made in accordance with the following formula No. 1. X + YT(F) C(G) = --------- formula No. (1) T(F) where, C(G) is the A350-800 Guaranteed DMC or A350-900 Guaranteed DMC per flight hour, as applicable, in US dollars specified in Paragraph 3, T(F) is the applicable A350 Aircraft average flight leg time, in hours. (i) For the A350-800 Aircraft: for the First Computation Period X is [...***...] per flight cycle, Y is [...***...] per flight hour, for the Second Computation Period X is [...***...] per flight cycle, Y is [...***...] per flight hour, (ii) For the A350-900 Aircraft: for the First Computation Period X is [...***...] per flight cycle, Y is [...***...] per flight hour, for the Second Computation Period X is [...***...] per flight cycle, Y is [...***...] per flight hour, 4.2 Should the applicable A350 Aircraft average usage rate differ from four thousand five hundred (4,500) flight hours by more than ten percent (10%), then the corresponding Guaranteed DMC values will be adjusted by the Seller accordingly. 5. REPORTING 5.1 The Buyers will provide the Seller with complete and detailed maintenance cost data ("A350 Maintenance Cost Data") annually, in English for each A350 Aircraft. The A350 ***Confidential Treatment Requested AWE/USA -A350 LA9-4 PRIVILEGED AND CONFIDENTIAL <PAGE> Maintenance Cost Data will include, as applicable: - A350 Aircraft MSN or registration number - All in-house accounting related to maintenance costs - All invoicing related to maintenance costs - Access to maintenance contracts where allowable - Maintenance reports - Pilots' reports - Operational data such as A350 Aircraft flight hours and flight cycles and auxiliary power unit running hours 5.2 If the Seller finds such A350 Maintenance Cost Data to be insufficiently detailed or unsubstantiated, the Buyers, using reasonable efforts, will supply additional data at the Seller's request. 5.3 With respect to maintenance or repairs subcontracted by the Buyers to, and performed by, third parties, the actual direct cost of consumed material will be deemed to be [...***...] of the price to the Buyers of such maintenance or repairs, if an insufficient breakdown of such maintenance or repair costs is supplied. 5.4 The Buyers will deliver the A350 Maintenance Cost Data not later than [...***...] following the end of each of its accounting years; and the Buyers will put at the Seller's disposal any documents, records, books, etc. necessary for validating the Buyers' information. 5.5 Should the Buyers not be able to provide sufficient Maintenance Cost Data to the Seller for the purpose of this Maintenance Cost Guarantee, the Buyers will notify the Seller within [...***...] after the end of the first of the Buyers' accounting years of the reasons why. If the Seller receives no A350 Maintenance Cost Data from the Buyers within [...***...] after the end of the second of the Buyers' accounting years occurring during the Duration, then the Direct Maintenance Costs will be considered acceptable to the Buyers and this Maintenance Cost Guarantee will automatically terminate. 6.

QUOTE 1. SCOPE The Buyer and the Seller agree they have a mutual interest in the technical reliability of the Buyer's Aircraft fleet to be of a high order, with a high probability that the aircraft will be Dispatched on time ("Dispatch Reliability"). This Letter Agreement extends to the Buyer's Aircraft fleet described in the Agreement and operated by the Buyer, a Dispatch Reliability guarantee (the "Guarantee"). 2. DURATION The obligations of the Buyer and the Seller under this Letter Agreement shall become binding upon signature of the Agreement and shall remain in force for a period of [...***...] from delivery of the first (1st) Aircraft to the Buyer (the "Duration"). At the end of the year following the Duration, the Buyer and the Seller will organise a Review Meeting as per Paragraph 9. At the occasion of this Review, if the Achieved Dispatch Reliability is confirmed and agreed by the Buyer and the Seller as below the Guaranteed Dispatch Reliability, the Seller will continue to make Recommendations in order to improve the Dispatch Reliability of the Buyer's fleet for the following year. These Buyer's and Seller's obligations will set in force until the Achieved Dispatch Reliability is above the Guaranteed Dispatch Reliability and for a period not exceeding [...***...] from delivery of the first (1st) Aircraft to the Buyer. 3. DEFINITIONS 3.1 ACHIEVED DISPATCH RELIABILITY The "Achieved Dispatch Reliability" is the actual dispatch reliability obtained by the Buyer's Aircraft fleet in regular Scheduled Revenue Flight service adjusted in accordance with the clauses of this Guarantee. ***Confidential Treatment Requested AWE/USA--A350 LA 13-2 PRIVILEGED AND CONFIDENTIAL <PAGE> Achieved Dispatch Reliability will be calculated for each Computation Period, expressed as a percentage, as follows: [...***...] 3.2 AIRCRAFT INHERENT MALFUNCTION An "Aircraft Inherent Malfunction" is a condition whereby maintenance actions confirm that the operation of a system or component is outside the specified limitations: a) as defined in the applicable Maintenance or Operations Manual(s), and/or b) has not been induced by a secondary cause or as a consequence of an Excluded Event as defined in paragraph 5. 3.3 CHARGEABLE EVENT Under this Guarantee a "Chargeable Event" is a Chargeable Delay or Chargeable Cancellation or Chargeable Return to Gate as defined hereunder. If analysis of substantiating data determines that the primary reason(s) for any Chargeable Event are not due to an Aircraft Inherent Malfunction or are due to an Excluded Event, such Chargeable Delay or Chargeable Cancellation shall not constitute a Chargeable Event. 3.3.1 A "Chargeable Delay" occurs when a confirmed Aircraft Inherent Malfunction directly results in an originating Scheduled Revenue Flight to be Dispatched more than [...***...] later than the scheduled time of departure. 3.3.2 A "Chargeable Return to Gate" occurs when the Aircraft, after being Dispatched returns to the parking position or gate, including a return to takeoff initiation (ground turn-back) or after takeoff initiation (aborted takeoff). 3.3.3 A "Chargeable Cancellation" occurs when a Scheduled Revenue Flight cannot take place as a direct result of a confirmed Aircraft Inherent Malfunction. Cancellation of any or all of the flight legs of a multi-leg flight if related to a Chargeable Event, constitutes and is counted as one Chargeable Event only. 3.4 COMMENCEMENT DATE The "Commencement Date" is the [...***...] following the month of delivery of the first Aircraft to the Buyer. 3.5 COMPUTATION PERIOD For the guarantee Duration each "Computation Period" consists of [...***...], the first to run from the commencement date to the [...***...] of the delivery date of the first Aircraft to the Buyer. Each subsequent Computation Period to run consecutively thereafter. ***Confidential Treatment Requested AWE/USA--A350 LA 13-3 PRIVILEGED AND CONFIDENTIAL <PAGE> 3.6 DISPATCHED Once an Aircraft has left the gate or stand for a Scheduled Revenue Flight it shall be deemed to have been "Dispatched", except as provided for in paragraph 3.3 above. 3.7 SCHEDULED REVENUE FLIGHT A "Scheduled Revenue Flight" is one originating flight operated by the Buyer using the Buyer's Aircraft delivered under the Agreement, available to be Dispatched prior to the original scheduled time of departure as stipulated: a) in the Buyer's timetable, as a scheduled flight, and/or b) in advance by the Buyer, as a charter flight. 4. GUARANTEE 4.1 GUARANTEED DISPATCH RELIABILITY The "Guaranteed Dispatch Reliability" exclusively relating to this Guarantee is solely as defined herein and provided in lieu of any and all other guarantees relating to Dispatch Reliability of any nature that may be stated, referenced or incorporated in any other document related to the Agreement. 4.1.1 Guaranteed Dispatch Reliability [...***...] The Seller guarantees that from the Commencement Date to the end of the [...***...] of Schedule Revenue Flight operation, on average, an Aircraft available to be Dispatched will have a [...***...] probability of being Dispatched without a Chargeable Event. 4.1.2 Guaranteed Dispatch Reliability The Seller guarantees that, for the [...***...] of Schedule Revenue Flight operation, on average, an Aircraft available to be Dispatched will have a [...***...] probability of being Dispatched without a Chargeable Event. 4.2 SUSPENSION OF GUARANTEE The provisions of this Guarantee shall not apply for any Computation Period during which: [...***...] where : [...***...] ***Confidential Treatment Requested AWE/USA--A350 LA 13-4 PRIVILEGED AND CONFIDENTIAL <PAGE> [...***...] 4.3 [...***...] 5. EXCLUSIONS Delays and/or cancellations due to any of the causes below are specifically excluded from this Guarantee, similarly if the Aircraft is consequently subject to a Chargeable Event. An "Excluded Event" is a delay or cancellation due to: a) Acts of third party b) Aircraft damage due to external forces such as lightning strikes, force majeure, personnel error or by passengers, etc. c) Buyer Furnished Equipment (BFE) or software embodied therein. d) Late arrival of the Aircraft, resulting in insufficient ground time for the Aircraft to be Dispatched at the scheduled departure time. e) Maintenance Staff untimely request and/or unavailability.
