14.Warranties; Limitation of Liability


image_2.jpg



14.1IAE 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.

14.2IAE 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.
14.3THE 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, 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.

15.Delays

15.1Excusable 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


image_2.jpg



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.

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).
