	10.7.5
	Should Spirit fail to make any material payments to IAE required as set forth in this Section 10 or should Spirit fail to make any material payments to IAE when due under any other agreement between IAE and Spirit and such amount is not subject to a good faith dispute between the Parties, then, notwithstanding any rights which IAE may have in contract or in law, IAE reserves the right to (a) assess interest on such late payment at the rate of the greater of ***** or the New York Citibank prime rate plus ***** per annum from the date the payment was due to be made until the date such payment is received by IAE, (b) suspend all work on any and all Eligible Engines then currently at the Maintenance Center pursuant to this FHA and/or (c) hold Eligible Engines in IAE’s possession or control.

	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.

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

	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”).

Exhibit 10.4




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.

	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:

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).
