Table of Contents

 Prior to/at Delivery of the first Aircraft, the Seller shall provide the Buyer with the
warranties and, where applicable, service life policies that the Seller has obtained for Supplier Parts pursuant to the supplier product support agreements to be entered into between the Buyer and the Seller prior to Delivery. 

 

	 	12.3.1	Definitions 

 “Supplier” means any supplier of Supplier Parts. 

“Supplier Part” means any component, equipment, accessory or part installed in an Aircraft at the time of Delivery thereof and
for which there exists a Supplier Product Support Agreement. For the sake of clarity, Propulsion Systems and Buyer Furnished Equipment and other equipment selected by the Buyer to be supplied by suppliers with whom the Seller has no existing
enforceable warranty agreements are not Supplier Parts. 
 “Supplier Product Support Agreements” means agreements between
the Seller and Suppliers to be negotiated in good faith between the Buyer and the Seller containing enforceable and transferable warranties and, in the case of landing gear suppliers, service life policies for selected structural landing gear
elements. 
  

	 	12.3.2	Supplier’s Default 

  

	 	(i)	In the event of any Supplier, under any standard warranty obtained by the Seller pursuant to Clause 12.3.1, ***** the Buyer submitting in reasonable time to the Seller reasonable proof that such default has occurred,
then Clause 12.1 shall apply to the extent the same would have been applicable had such Supplier Part been a Warranted Part, except that the Supplier’s warranty period as indicated in the Supplier Product Support Agreement shall apply

  

	 	(ii)	In the event of any Supplier, under any Supplier Service Life Policy obtained by the Seller pursuant to Clause 12.3.1, ***** and the Buyer submitting in reasonable time to the Seller reasonable proof that such default
has occurred, then Clause 12.2 shall apply to the extent the same would have been applicable had such Supplier Item been listed in Exhibit F, Seller Service Life Policy, except that the Supplier’s Service Life Policy period as indicated in the
Supplier Product Support Agreement shall apply. 

  

	 	(iii)	At the Seller’s request, the Buyer shall assign to the Seller, and the Seller shall be subrogated to, all of the Buyer’s rights against the relevant

Supplier with respect to and arising by reason of such default and shall provide reasonable assistance to enable the Seller to enforce the rights so assigned. 

 

	12.4	Interface Commitment 

  

	 	12.4.1	Interface Problem 

 If the Buyer experiences any technical problem in the operation of an
Aircraft or its systems due to a malfunction, the cause of which, after due and reasonable investigation, is not readily identifiable by the Buyer but which the Buyer reasonably believes to be attributable to the design characteristics of one or
more components of the Aircraft (the “Interface Problem”), the Seller shall, if so requested by the Buyer, and without additional charge to the Buyer except for transportation of the Seller’s personnel to the Buyer’s
facilities, promptly conduct or have conducted an investigation and analysis of such problem to determine, if possible, the cause or causes of the problem and to recommend such corrective action as may be feasible. The Buyer shall furnish to the
Seller all data and information in the Buyer’s possession relevant to the Interface Problem and shall cooperate with the Seller in the conduct of the Seller’s investigations and such tests as may be required. At the conclusion of such
investigation, the Seller shall promptly advise the Buyer in writing of the Seller’s opinion as to the cause or causes of the Interface Problem and the Seller’s recommendations as to corrective action. 

 

	 	12.4.2	Seller’s Responsibility 

 If the Seller determines that the Interface Problem is primarily
attributable to the design of a Warranted Part, the Seller shall, if so requested by the Buyer and pursuant to the terms and conditions of Clause 12.1, correct the design of such Warranted Part to the extent of the Seller’s obligation as
defined in Clause 12.1. 
  

	 	12.4.3	Supplier’s Responsibility 

 If the Seller determines that the Interface Problem is
primarily attributable to the design of any Supplier Part, the Seller shall, if so requested by the Buyer, reasonably assist the Buyer in processing any warranty claim the Buyer may have against the Supplier. 

 

	 	12.4.4	Joint Responsibility 

 If the Seller determines that the Interface Problem is attributable
partially to the design of a Warranted Part and partially to the design of any Supplier Part, the Seller shall, if so requested by the Buyer, seek a solution to the Interface Problem through cooperative efforts of the Seller and any Supplier
involved. The Seller shall promptly advise the Buyer of such corrective action as may be proposed by the Seller and any such Supplier. Such proposal shall be consistent with any then existing obligations of the Seller hereunder and of any such
Supplier towards the 

  
 29 

Table of Contents

 
Buyer. Such corrective action, when accepted by the Buyer, shall constitute full satisfaction of any claim the Buyer may have against either the Seller or any such Supplier with respect to such
Interface Problem.

	 	(i)	All requests under this Clause 12.4 shall be directed to both the Seller and the Supplier.

release and renunciation by the Buyer set forth in Clause 12.5. 

  

	12.8	Disclosure to Third Party Entity 

 In the event of the Buyer intending to designate a
third party entity (a “Third Party Entity”) to administrate this Clause 12, the Buyer shall notify the Seller of such intention prior to any disclosure of this Clause to the selected Third Party Entity and shall cause such Third
Party Entity to enter into a confidentiality agreement and or any other relevant documentation with the Seller solely for the purpose of administrating this Clause 12.

	 	(a)	the United States Department of Labor substantially revises the methodology of calculation of the Labor Index or the Material Index as used in the Airframe Price Revision Formula, or 

 

	 	(b)	the United States Department of Labor discontinues, either temporarily or permanently, such Labor Index or such Material Index, or

calculation of the original Labor Index or Material Index as the case may be. 
 As a result of the selection of the Substitute Index, the
Seller shall make an appropriate adjustment to the Airframe Price Revision Formula to combine the successive utilization of the original Labor Index or Material Index (as the case may be) and of the Substitute Index. 

 

	5.3	Final Index Values 

 The Index values as defined in Clause 4 above shall be considered
final and no further adjustment to the base prices as revised at Delivery of the Aircraft shall be made after Aircraft Delivery for any subsequent changes in the published Index values.
