Amendment No. 31 to Special Business Provisions MS ###-###-####, between the Boeing Company and Spirit AeroSystems, Inc., dated as of October 18, 2017

Boeing and Seller are Parties to the Administrative Agreement (AA) AA ###-###-####, General Terms Agreements (GTA) BCA ###-###-#### and Special Business Provisions (SBP) MS ###-###-####, together with all Amendments thereto (collectively, the “Supply Contract”).

Boeing and Seller herein memorialize (i) a final incurred cost for the 737-8 Rate Tooling, and (ii) a final 737-8 Rate Tooling Incentive payment (“Incentive”), all in accordance with SBP Attachment 27.

For purposes of this Amendment No. 31, “737-8 Rate Tooling” is defined as such Rate Tooling as is necessary to support a build rate of up to [*****] APM for the 737-8, in accordance with SBP Attachment 27.

The Parties are in agreement that the total incurred costs for 737-8 Rate Tooling, including the Incentive amount as specified in Table 1 below, are $[*****]. Of this total, Boeing agrees to pay Seller $[*****] as settlement for the Incentive award earned for tooling incurred cost underruns to the [*****] amount listed in Exhibit A of SBP Attachment 27.

Exhibit A to this Amendment No. 31 spreads the costs of the Incentive amount to the costs for each of the 737-8 Rate tools for the adjusted tool costs. The Parties are in agreement that the adjusted tool costs will be the amounts entered by Boeing Tools & Accountability into the Boeing’s Certified Tool Tracking Log (“CTOL”) System upon acceptance of the final Certified Tool Lists (“CTL”) as described in section 6.4.1 of SBP Attachment 27.

The following provisions are further agreed between the Parties:

The Tools listed in Exhibit A as “Pending Tools” are additional Rate Tools needed for the production of the 737-8 airplane supporting a [*****] Airplane Per Month (“APM”) production rate which have not been manufactured as of the Effective Date of this Amendment No. 31. Costs for these tools will not be subject to reimbursement nor incentive payment by Boeing for costs incurred by Spirit. Spirit will submit a zero-cost ($0) CTL to Boeing pursuant to the process guidelines set forth in the Suppliers Tooling Document, D33200-1, upon tool build completion.

All 737-8 Rate Tooling and Incentive payments for up to [*****] APM are hereby closed in accordance with the requirements of this Amendment No. 31. For purposes of clarity, the payments required from Boeing to Seller under this Amendment No. 31 are separate and apart from those payments required by Section 8 of SBP Attachment 1.

If additional 737-8 Rate Tooling is needed to support a build rate of up to [*****] APM for the 737-8 beyond that Rate Tooling already identified within this Amendment No. 31, Seller will submit a zero dollar CTL for such additional Rate Tools pursuant to the process guidelines set forth in D33200-1.

If Product non-conformances result from a defective Seller-procured/fabricated 737-8 Rate Tool, Seller will rework or replace such defective 737-8 Rate Tools at no cost to Boeing and Seller will submit a no cost CTL.

Any changes to the Rate Tooling on the 737-8, directed post Amended Type Certification (“ATC”), will be processed in accordance with the terms and conditions of the SBP.

Final CTLs: The Parties agree that all 737-8 Rate Tooling CTLs representing the above-referenced 737-8 Rate Tooling incurred costs of $[*****] have been submitted to Boeing by Seller and approved by Boeing. The Parties further agree to adjust the values on these CTLs pursuant to paragraph 1b to represent the total cost to Boeing of $[*****] (see Table 1 - 737-8 Rate Tooling Incentive Settlement).

Invoicing and Payment: Upon notification from Boeing (via purchase order) Spirit shall submit invoicing pursuant to the purchase order numbers and purchase order values noted in the table in section 2 above. Payment shall be authorized pursuant to the terms of the SBP Attachment 27 Section 6.1.2 upon submittal of an acceptable CTL received from Spirit. The Parties agree that Boeing will provide a Purchase Order(s) inclusive of the 737-8 Rate Tooling Incentive within [*****] calendar days of the Effective Date and Seller will submit an invoice shortly thereafter. Payment terms shall be net [*****] calendar days after receipt of a correct and valid invoice, pursuant to SBP Section 5.2.1.

The SBP is hereby amended to include the following Purchase Orders within SBP Attachment 27 Section 6.3:

The SBP is hereby amended by replacing the 737-8 Rate Tooling list within Attachment 27 Exhibit C with the 737-8 Rate Tooling list contained within Exhibit A to this Amendment No. 31. For avoidance of doubt, the Initial Tools listed in SBP Attachment 27 Exhibit C remain unchanged.

Except as specifically set forth herein, all provisions of the SBP shall remain unchanged and in full force and effect.

In the event of a conflict between the terms of this Amendment No. 31 and provisions of the SBP, GTA, or the Administrative Agreement, this Amendment No. 31 shall take precedence.

This Amendment No. 31 shall be governed by the internal laws of the State of Washington without reference to any rules governing conflict of laws.
