1.1.The list of Amendments of the Agreement is hereby deleted in its entirety and replaced as follows:

Notwithstanding the payment due dates for Shipsets specified elsewhere in this SBP, Boeing shall make total advance payments to Spirit for Shipsets in the amount of $[****] (“Advance Payments”). The schedule for Boeing’s Advance Payments shall be as follows: $[****] shall be due on [****]; an additional $[****] shall be due on each of [****], [****], [****] and [****]; an additional $[****] shall be due on each of [****], [****], [****] and [****]; an additional $[****] shall be due on [****]; an additional $[****] shall be due on [****]; an additional $[****] shall be due on [****] and [****]; and an additional $[****] shall be due on [****]. Excepting the [****] payment, Spirit shall invoice Boeing [****] days prior to these dates. These payments are made for the Work Statement set forth in Attachment 1 - “Work Statement and Pricing”. Notwithstanding anything to the contrary contained herein, in the GTA or in any other agreement between Boeing and Spirit, Boeing shall not be entitled to any offset or credit of the Advance Payments for any amounts owed by Spirit to Boeing under this SBP or otherwise.

The Advance Payments shall be applied against payments due by Boeing to Spirit for the first [****] Shipsets such that the Shipset Price, for each of the first [****] Shipsets shall be decreased as follows: $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; $[****] for Shipsets [****]; and $[****] for Shipsets [****].

In the event that Boeing does not take delivery of [****] Shipsets under the terms of this SBP prior to the termination of the Program or this SBP, the remaining balance of the Advance Payments shall be first applied against any outstanding payments

then due by Boeing to Spirit in respect of the 787 program. Finally, any remaining balance shall be prorated at an equivalent rate of [****] Shipsets per year, beginning in the month following delivery to Boeing of Spirit’s final production Shipset. Spirit shall make a payment to Boeing on December 15 of each year for the payments due on account of such year until any remaining balance of the Advance Payments has been fully recovered.

1.3.SBP Attachment 1 is here by amended and restated in its entirety as follows:

As of Amendment 39, Boeing will pay Spirit $[****] via incremental 787 recurring Shipset Price increases effective at LN [****] through LN [****]. The per Shipset Price shall be rate variable and as set forth in Attachment 1, Recurring Shipset Price (All Minor Models). No later than 10 business days after execution of Amendment 39, Boeing will amend any outstanding purchase orders as necessary to reflect the pricing shown in Attachment 1, Recurring Shipset Price (All Minor Models). No later than 15 business days after execution of Amendment 39, the Parties will jointly reconcile pricing for any Products already delivered starting with Line Number [****] through such time as the purchase orders are amended with pricing as shown in Attachment 1, Recurring Shipset Price (All Minor Models). No later than 3 business days after the Parties complete the reconciliation, Boeing will pay to Spirit the reconciliation value via wire transfer.

Within 30 days following the delivery of Line Number [****] from Spirit to Boeing, the Parties will reconcile the adjusted pricing set forth in Attachment 1, Recurring Shipset Price (All Minor Models) against the 787 Shipset pricing as of 787 SBP Amendment 37. In the event the incremental amounts paid to Spirit do not total $[****], the respective Party will pay, via wire transfer, any amount due within 10 business days of completing the reconciliation. For clarity, any Shipset pricing revisions subsequent to Amendment 39 resulting from statement of work revisions/changes will not be applied towards the $[****] incremental Shipset Price increase.

The Parties, at either’s request, agree to meet at a mutually agreeable time, with a mutual goal of concluding negotiations 12 months prior to the delivery of LN [****], to discuss in good faith potential pricing changes, other interests and considerations pertaining to LN [****] and beyond.
