Amendment

On the basis of the foregoing, the Agreement is amended as follows, effective as of the Effective Date:

1. Signing Bonus - Restricted Stock

Section 3(b)(ii)-(iii) of the Agreement, relating to your LTIP award signing bonus, is amended in its entirety to read as follows:

(ii) Signing Bonus - Restricted Stock Subject to approval by the Holdings board of directors, in consideration of entering into this Agreement, we will grant you a one-time award of $440,000 of restricted stock (the “Bonus Shares”) under the Spirit AeroSystems Holdings, Inc. Long-Term Incentive Plan, as amended or restated from time to time (the “LTIP”), subject to the terms and provisions of the LTIP and this Section 3(b). The Bonus Shares will vest in accordance with the following vesting schedule:

Years of Service Percent Vested

After Effective Grant Date in Bonus Shares

Less than 2 0%

2 but less than 3 33%

3 but less than 4 66%

4 or more 100%

For purposes of this vesting schedule, the “Effective Grant Date” will be May 7, 2013, which is the same date grants of shares under the LTIP were made to the broad class of LTIP participants for 2013, with the effect that the Bonus Shares will vest on the same schedule as the shares previously awarded to the broad class of LTIP participants for 2013. You will be credited with a year of service after the Effective Grant Date for each 12-month period after the Effective Grant Date during which you are continuously performing services (or deemed to be continuously performing services) for us.

(i)Number of Shares For purposes of determining the number of shares of stock to be granted in connection with the award described in the foregoing clause (ii), the total dollar value of the award will be divided by an amount equal to the average of the opening value and the closing value of a share of our Class A common stock traded on the New York Stock Exchange, as determined on the third trading day after the date on which we publicly announce our earnings for the second fiscal quarter of 2013. The number of shares so determined with respect to each award will be rounded up to the nearest whole number.
