such Spare Engine to Willis. If such Spare Engine or Spare Engine Part is returned in accordance with IAE’s written shipping instructions, and determined by IAE in its sole discretion to have been defective at the time of Delivery, IAE will bear the cost of round-trip transportation of such Spare Engine or Spare Engine Part and the risk of loss thereof. Except as expressly set forth below, IAE makes no warranty and disclaims all liability for goods, equipment and parts, whether supplied by IAE or not, that were not originally manufactured by or on behalf of IAE, though IAE will, to the extent it has a right to do so, make available to Willis the benefit of any warranty provided by the original manufacturer of such good, equipment or part (including, without limitation, in respect of the Engine Bag and Engine Stand). IAE warrants to Willis and its successors and permitted assigns that, at the time of conveyance to Willis, IAE will convey good and marketable title to the Spare Engines, the Engine Bags and the Engine Stands, free and clear of all liens, claims, charges and encumbrances whatsoever (collectively, “Liens”), and to the extent such title is not good and marketable or any Spare Engine, Engine Bag or Engine Stand is not free and clear of all Liens as warranted herein, IAE will address and defend all claims and demands to ensure conveyance of good and marketable title to, and the removal of any Liens against, the Spare Engines, the Engine Bags and the Engine Stands, and will indemnify and hold Willis harmless in connection therewith. In addition, IAE grants and Willis accepts the [*] Engine and Parts Service Policy as set forth in Appendix 3 attached hereto (the warranties collectively stated in this Section 3.1, the “Warranties”).

3.2 The Warranties may not be assigned without the prior written consent of IAE (such consent not to be unreasonably withheld). Notwithstanding the foregoing, Willis may assign the Warranties to any Permitted Affiliate without IAE’s consent provided that Willis provides IAE with a notice of such assignment to [*] that (i) identifies the Permitted Affiliate; (ii) identifies the relevant Spare Engine serial number(s); and (iii) waives Willis’s right to receive any further benefits under the Warranties with respect to the relevant Spare Engine(s). Any assignment made in violation of this Section 3.2 is null and void.

3.3 The Warranties provide specified benefits or remedies to Willis as a result of specified events. Under no circumstances will duplicate benefits or remedies be provided to Willis by IAE or any other source (e.g., an equipment manufacturer) as a result of the same event or cause. Therefore, notwithstanding any terms of the Warranties to the contrary, Willis waives its eligibility to receive benefits or remedies from IAE if it is eligible to receive or has received duplicative benefits or remedies from IAE or any other source as a result of the same event or cause.

3.4 IAE makes no representation or warranty and IAE accepts no obligation whatsoever, except to the extent set forth in Section 8.15, with respect to any events, occurrences or circumstances arising after Delivery, or any actions of Willis at any time, that might directly or indirectly affect in any way the title of any Spare Engine. Moreover, with the exception of the express Warranties set forth in this Contract, IAE does not make any express or implied warranty, guarantee or representation with respect to the Spare Engines, Engine Bags or Engine Stands, and hereby EXPRESSLY DISCLAIMS ANY AND ALL WARRANTIES,

3.5 Willis accepts that the Warranties granted to Willis hereunder, together with the express remedies provided herein, are expressly in lieu of, and Willis hereby waives, all other remedies, conditions, guarantees and warranties, whether expressed or implied, including without limitation ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, and all other obligations and liabilities whatsoever of IAE and of its shareholders whether in contract, in tort or otherwise, for any defect, deficiency, failure, malfunction or failure to function of any Spare Engines or of the equipment referred to herein, howsoever and whenever acquired by Willis from whatever source. Neither IAE nor any of its shareholders will be liable to Willis upon any claim therefor or upon any claim howsoever arising from the manufacture, supply or inspection by IAE or any of its shareholders of any Spare Engine, Engine Bag, Engine Stand or any other item of whatever nature, whether in contract, tort or otherwise, except (i) as expressly provided in the Warranties or (ii) any liability arising from IAE’s gross negligence or willful misconduct, and Willis assumes all risk and liability whatsoever not expressly assumed by IAE in the Warranties. In no event will IAE be liable to Willis for special, incidental, indirect or consequential damages arising in connection with or related to this Contract or the subject of this Contract, including but not limited to damage to, loss of use, revenue or profit, relating to any Spare Engine, any Aircraft on which a Spare Engine is installed, or any Engine Bag or Engine Stand.

3.6 This Article 3 has been the subject of discussion and negotiation and is fully understood by the Parties. The purchase prices of the Spare Engines, and the agreements of the Parties set forth in this Contract, are derived in consideration of:

3.6.1 the express Warranties of IAE and Willis’s rights thereunder; and

3.6.2 the exclusions, waivers and limitations set forth in Section 3.5.

4. SUBJECT TO PRIOR SALE

The Parties acknowledge that the Delivery Dates set forth in this contract are tentative and will only be confirmed (thereby triggering IAE’s obligation to satisfy its obligations to Deliver) upon Willis’s payment of [*] in accordance with Section 2.4 and submission of a complete purchase order with IAE for each of the Spare Engines, subject to Section 6.
