[***]

13.2 [***]

14. Warranties; Limitation of Liability

14.1 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.

14.2 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.

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.

14.3 THE WARRANTIES SET FORTH HEREIN AND/OR IN THE NEW ENGINE FLEET GTA TOGETHER WITH THE EXPRESS REMEDIES PROVIDED TO SPIRIT IN ACCORDANCE WITH THIS AGREEMENT AND/OR SUCH NEW ENGINE FLEET GTA, 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.

14.4 [***]

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

15. Delays

15.1 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").

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.

16. Duplicate Benefits

Spirit and IAE agree that it is not the intention to provide duplicate benefits under the terms of this Agreement and the 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 duplicate benefits.

17. Intellectual Property

17.1 In the event any suit, claim or action is brought against Spirit (or a person expressly indemnified by Spirit) alleging that, without further combination, Spirit's use or resale of (a) goods (b) a part made by or under IAE's control and in accordance with the specification or design provided by IAE or (c) a process embodied in the goods delivered to Spirit by IAE infringes any patents, IAE will, at its own expense, conduct the entire defense including any and all necessary court action, settlements, and appeals. IAE will either settle such claim or pay all damages and costs awarded in a non-appealable judgment, excluding indirect, incidental, special, consequential, and punitive damages. If the use or resale of such goods or part(s) is finally enjoined, IAE will, at its option: (a) procure for Spirit the right to use or resell such goods or parts; (b) replace such goods or parts with equivalent non-infringing parts; (c) modify such goods or parts so they become non-infringing but equivalent; or (d) remove such goods or part(s) and refund the purchase price (less a reasonable allowance for use, damage or obsolescence).

17.2 The preceding provision is applicable only if the following conditions are met: (a) the goods, part(s), services, or process involved in the suit, claim, or action must have been provided under this Agreement during Maintenance Services in accordance with this Agreement, as applicable; (b) the alleged infringement must be an infringement of any patents of the nation in which Spirit's principal place of business is located or a jurisdiction within which the relevant Supplies were manufactured or delivered to Spirit; (c) Spirit must provide IAE with timely notice of such suit, claim, or action and the full opportunity to assume the entire defense thereof; and (d) Spirit must provide IAE with all information available to Spirit and other defendants pertaining to the alleged infringement.

17.3 For the avoidance of doubt, this provision will not apply to (a) any alleged patent infringement in any nation other than as specified above; (b) any Spirit-furnished specification or design or the performance of a process not recommended in writing by IAE; (c) any goods or parts or components thereof manufactured according to a non-IAE specification or design; (d) the use or sale of goods or parts delivered hereunder in combination with other goods not delivered to Spirit by IAE; or (e) any instance not specified in the preceding paragraphs. In such instances, Spirit will indemnify and hold IAE harmless.

18. 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.

19. Assignment

19.1 Except as otherwise 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).

19.2 [***]

19.3 [***]

19.4 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.

21.1 This Agreement and the New Engine Fleet GTA constitute the 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.

21.2 The Parties agree that neither of them have placed any reliance whatsoever on any representations, agreements, statements or understandings made prior to the signature of this Agreement, whether orally or in writing, relating to such services, other than those expressly incorporated in this Agreement, which has been negotiated on the basis that its provisions represent their entire agreement relating to such services and shall supersede all such representations, agreements, statements and understandings.

22. Termination, Expiration and Events of Default

22.2 Failure to Make Payments or to Meet Obligations

22.2.1 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.

22.2.2 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 10.5 for the duration of the Period of Cover (subject to the fleet flexibility granted in Section 11), 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.

22.2.3 Spirit shall have the right to terminate this Agreement in the event that IAE fails to: (i) pay or provide any credit payable hereunder when due and such failure is not cured within [***] or (ii) perform a material obligation in accordance with the terms hereof and such failure continues unremedied for a period in excess of [***] or such failure reoccurs in at least [***] consecutive shop visits after IAE was first given written notice of such failure by Spirit, provided however that in no event shall IAE have fewer than [***] to cure such failure.

22.3 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 22. Notwithstanding the foregoing, Sections 22.4, 25, and 27

of this Agreement shall survive any expiration or termination of this Agreement.

22.4 Effect of Termination or Expiration

Except as otherwise set out in this Section 22.4 and any rights or obligations arising under the applicable law, the rights and obligations of the Parties under this Agreement shall terminate upon the termination or expiration of this Agreement, and Spirit shall no longer be provided with fleet hour agreement coverage under the terms of this Agreement.

22.4.1 Upon any termination or expiration of this Agreement, all liabilities and obligations (including payment obligations) that have accrued prior to such termination or expiration (including payment due for Excess Work) shall survive.

Exhibit I

FHA Rate Adjustment Tables

The FHA Rates have been calculated based on Spirit meeting the General Conditions detailed in Section 10.4 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. If the actual operation of the Eligible Engines falls between the points covered in any one of the tables, the adjustment factor can be interpolated linearly between the points to derive the applicable factor. 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).
