10.8.1			In addition to amounts stated to be payable by Spirit pursuant to this Agreement, Spirit shall pay any and all imposts, taxes, duties, levies, fees, assessments or other like charges (excluding any income, gains, or excess profit, franchise and similar taxes levied on the part of IAE, any Maintenance Center or their respective Affiliates and subcontractors,) which may be imposed by any government or taxing agency thereof arising from performance by IAE or its subcontractors in connection with this Agreement.



10.8.2			All amounts stated to be payable by Spirit pursuant to this Agreement exclude any value added tax, sales tax or similar such tax. In the event that the supply of goods or services under this Agreement is chargeable to any value added tax, sales tax or similar such tax will be borne by Spirit, subject to the receipt of any appropriate documentation that may be required to enable or assist Spirit to claim or verify any tax credit, set off, rebate or refund in respect of such taxes paid or payable in connection with supplies under this Agreement.



10.8.3			If either IAE or Spirit becomes aware of any taxes set forth in Sections 10.8.1 and 10.8.2 above, the relevant Party shall promptly notify the other Party, and both parties agree to consult in good faith and take such other reasonable steps in order to mitigate the tax in question.



11.			[***]



12.			Warranties; Limitation of Liability



12.1			IAE warrants the work performed by a Maintenance Center at the final Shop Visit for each Eligible Engine under this Agreement shall be free from defects in materials and workmanship as follows: If Spirit demonstrates to the reasonable satisfaction of IAE that a defect in the work performed on a Part has caused damage to such Part or any other Part, and Spirit provides written notice to IAE of such damage within [*] or within [] after installation of the corresponding Eligible Engine on an Aircraft, or if not installed on an Aircraft, within [**] after delivery of the Eligible Engine from the applicable Shop Visit, whichever occurs first, IAE shall, as its sole responsibility for such defect, repair such damage at IAE's own cost and expense. Transportation charges for the return of defectively serviced goods to IAE or the Maintenance Center, and their reshipment to Spirit and risk of loss thereof shall be borne by IAE only if such goods are returned in accordance with reasonable written shipping instructions from IAE.

Page 19 of 19



12.2			IAE warrants to Spirit that it shall convey good title to the new Parts sold hereunder. IAE's liability and Spirit's remedy under this warranty are limited to the removal of any title defect or, at the election of IAE, to the replacement of the new Parts or components thereof which are defective in title; provided, however, that the rights and remedies of the Parties with respect to patent infringement shall be limited to the provisions of Section 15 of this Agreement. Spirit warrants that title to Parts removed from Eligible Engines by the Maintenance Center shall pass immediately to IAE free and clear of all security interests and rights of Spirit or others at the time that title to the replacement Part passes to Spirit.



12.3			THE FOREGOING WARRANTIES TOGETHER WITH THE EXPRESS REMEDIES PROVIDED TO SPIRIT IN ACCORDANCE WITH THIS AGREEMENT, ARE EXCLUSIVE AND ARE GIVEN BY IAE IN LIEU OF (A) ANY AND ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE; AND (B) ANY OBLIGATION, LIABILITY, RIGHT, CLAIM, OR REMEDY IN STATUTE, CONTRACT, TORT OR STRICT LIABILITY AGAINST OEM OR ITS AFFILIATES, WHETHER OR NOT ARISING FROM THE NEGLIGENCE, ACTUAL OR IMPUTED (BUT NOT GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), OF IAE OR ITS AFFILIATES, STOCKHOLDERS, DIRECTORS, OFFICERS, EMPLOYEES, PERMITTED ASSIGNS AND AGENTS.



12.4			[***]



12.5			For purpose of this Section 12, "IAE" shall be deemed to include IAE International Aero Engines AG, Pratt and Whitney, a division of United Technologies Corporation, Pratt & Whitney Aero Engines International GmbH, Japanese Aero Engine Corporation, MTU Aero Engines GmbH, and the respective directors, officers, employees and agents of each.



13.			Delays



13.1			Excusable Delays

IAE shall not be charged with any liability for delay in the performance of any of its obligations when such delay is caused by acts of God or the public enemy, compliance in good faith with any applicable foreign or domestic governmental regulation or order whether or not it proves to be invalid, fires, riots, labor disputes, unusually severe weather, or any cause beyond the reasonable control of IAE, or by delays of IAE's suppliers for any of the same or similar causes. To the extent that such causes actually delay performance on the part of IAE, the time for the performance shall be extended for as many days as are required to obtain removal of such causes. This provision shall not, however, relieve IAE from using its reasonable efforts to avoid or remove such causes and continue performance with reasonable dispatch whenever such causes are removed ("Excusable Delay").

Page 20 of 20

If Spirit fails to comply with the requirements set forth in Section 9, and such failure or non-approval, as applicable causes the Maintenance Center to reasonably reschedule or delay the induction or completion of a Shop Visit for an Eligible Engine, then such delay shall constitute an Excusable Delay for IAE.



14.			Duplicate Benefits

Spirit and IAE agree that it is not the intention to provide duplicate benefits under the terms of this Agreement and the Existing Fleet GTA or under any other arrangement between IAE or IAE's suppliers or Airbus and Spirit. In the event of any such duplication of benefits, Spirit may, at the relevant time in respect of the relevant circumstances receive any one such benefit (at Spirit's discretion) to the exclusion of all other duplicate benefits.



15.			Intellectual Property



15.1			IAE shall conduct, at its own expense, the entire defense of any claim, suit or action alleging that, without further combination, the use or resale by Spirit or any subsequent purchaser or user of the Parts delivered hereunder directly infringes any United States patent or any patent of any other country that is a signatory to Article 27 of the Convention of International Aviation signed by the United States at Chicago on December 7, 1944, in which Spirit is authorized to operate, but only on the condition that:



15.1.1			IAE receives prompt written notice of such claim, suit or action and has full opportunity and authority to assume the sole defense thereof, including settlement and appeals, and all information available to Spirit or subsequent purchaser or user for such defense; provided, however, IAE shall not agree to any settlement pursuant to which any fault is attributed to Spirit, without the prior written consent of Spirit;



15.1.2			such new Parts are made according to a specification or design furnished by IAE or, if a process patent is involved, the process performed with such Parts if recommended in writing by IAE; and



15.1.3			the claim, suit or action is brought against Spirit.



15.2			Provided all of the foregoing conditions have been met, IAE shall, at its own expense, either settle said claim, suit or action or shall pay all damages, excluding consequential damages and costs awarded by the court thereon, and, if the use or resale of such new Parts is finally enjoined, IAE shall, at IAE's option:



15.2.1			procure for Spirit the right to use and resell the new Parts,



15.2.2			replace them with equivalent non-infringing Parts,



15.2.3			modify them so they become non-infringing but equivalent, or

Page 21 of 21



15.2.4			remove them and refund the purchase price and any additional amount necessary to replace the same with equivalent, non-infringing Parts (less a reasonable allowance for use, damage and obsolescence).



15.3			If a claim, suit or action is based on a design or specification furnished by Spirit or on the performance of a process not recommended or approved in writing by IAE, or on the use or sale of the Parts delivered hereunder in combination with other new parts not delivered to Spirit by IAE, Spirit shall indemnify and save IAE harmless therefrom.



16.			Amendment

This Agreement shall not be amended, changed, or modified in any way other than by agreement in writing, signed by the Parties hereto after the date of this Agreement, which is expressly stated to amend this Agreement.



17.			Assignment



17.1			Except as other agreed herein, Spirit may not assign in whole or part any of its rights or obligations under this Agreement without the written consent of IAE (such consent not to be unreasonably withheld).



17.2			[***]



17.3			[***]



17.4			IAE may, without recourse, assign its rights and/or delegate its obligations under this Agreement to any subsidiary or affiliate of IAE or United Technologies Corporation, or in connection with a merger, consolidation, reorganization, or voluntary sale or transfer of its assets; provided that such assignee/delegate is: (i) solvent at the time of such transfer and (ii) authorized by the applicable regulatory authorities, as necessary, to perform or procure the performance of all obligations being delegated/assigned; and (iii) able, in IAE's sole, reasonable discretion, to make all payments required by IAE to be made to Spirit under this Agreement.



18.			Notices

Any notice to be served pursuant to this Agreement shall be sent by registered mail, by internationally recognized overnight courier, or by facsimile (with the original notice sent by registered mail or internationally recognized overnight courier) to the applicable address indicated in Exhibit F.



19.			Exclusion of Other Provisions and Previous Understandings



19.1			This Agreement is the sole and entire agreement of the Parties with respect to the Eligible Engines and the subject matter hereof and shall apply to the exclusion of any other provisions on or attached to or otherwise forming part of any order form of Spirit, or any acknowledgment or acceptance by IAE, or of any other document which may be issued by either Party relating to such services and the Eligible Engines.

Page 22 of 22

20.2			Failure to Make Payments or to Meet Obligations



20.2.1			If Spirit fails to make any payment of a material amount, due and owing to IAE as set forth in Section 10 of this Agreement or any other agreement between the Parties (including any late interest due thereon) and such amount is not the subject of a good faith dispute or fails to meet any other material obligation under this Agreement or any other agreement between the Parties, then, after notice to Spirit and the expiration of a [***] cure period, and without prejudice to any of IAE's other rights which IAE may have in contract, at law, or in equity, IAE shall have the right to not to induct, to suspend all work on, or not to release from the Maintenance Center(s) any Eligible Engine until full payment is made by Spirit to IAE or such failure is corrected, as the case may be.



20.2.2			If Spirit fails to take delivery of all of the Aircraft and Eligible Engines in accordance with the schedule set forth in Exhibit A to this Agreement, as amended, supplemented or otherwise modified from time to time, or fails to operate the Aircraft and Eligible Engines in regular commercial service as contemplated by Section 10.6 for the duration of the Period of Cover, in addition to any other rights which IAE may have in contract, at law, or in equity, IAE shall be entitled to make reasonable adjustments to the FHA Rates as appropriate based on the method of calculation used to derive the FHA Rates.



20.2.3			A non-defaulting Party shall have the right to declare an event of default and terminate this Agreement: (i) if any default shall occur in the payment by the defaulting party of any material amount hereunder when and as the same becomes due and payable and such default continues, after notice from the non-defaulting Party for a period of [*] or more and is not the subject of a good faith dispute between the Parties, or (ii) for a failure by the defaulting Party to meet any other material obligation under this Agreement, and such failure has not been fully corrected within [*] after the non-defaulting Party has given notice of such failure to the defaulting Party and is not the subject of a good faith dispute between the Parties.

Page 23 of 23



20.3			Expiration

This Agreement shall be effective from the day and year first before written until the end of the Period of Cover or until terminated pursuant to this Section 20. Notwithstanding the foregoing, Sections 20.4, 23, and 25 of this Agreement shall survive any expiration or termination of this Agreement.



20.4			Effect of Termination or Expiration

Exhibit I
FHA Rate Adjustment Tables

The FHA Rates have been calculated based on Spirit meeting the General Conditions detailed in Section 10.6 of the Agreement.

To the extent that any operating parameters vary, the applicable charges shall be generated from the rate change tables contained in this Exhibit I. In the event that Spirit's actual operating conditions fall between points in the FHA Rate Adjustment Matrices, IAE shall use the Microsoft Excel spreadsheets referenced in Exhibit I hereto to calculate the applicable FHA Rate using linear interpolation (the "FHA Rate Interpolation Tool"). If the actual utilization parameters fall between two separate tables, the table with the higher factor shall apply.

If any of the actual operating parameters fall outside the coverage of the tables contained in this Exhibit I, the Parties shall agree a rate adjustment based on the same method of calculation used to derive the tables (and not based on simple extrapolation).
