Dear Sir/Madam,
We refer to the agreement for the sale and purchase of the shares of S.R.I.F. NV
among Christian Boas, Emile Boas, Dreda general partnership under Belgian law
and Sylvie Boas (together, the “Sellers”), Spirit AeroSystems Belgium Holdings
BVBA (the “Purchaser”) and Spirit AeroSystems Holdings, Inc. (together with the
Purchaser, “Spirit”), as amended by the Letter Agreements dated March 19, 2019
and March 27, 2019 (the “Agreement”).
As it is our understanding that the Parties desire to extend the Long Stop Date
in order to provide additional time for the Competition Condition to be
satisfied, we hereby seek the agreement of the Sellers to replace and restate
the definition of Long Stop Date in the Agreement as follows:
“Long Stop Date means July 15, 2019;”
Additionally, in order to address capital expenditures budgeted by the Group
Companies as of the Signing Date which have not been made prior to the Closing,
the Parties hereby agree that no later than May 14, 2019, they will agree to
amend the SPA to provide for certain minor administrative changes described on
Exhibit A hereto.
The Parties acknowledge and agree that this letter agreement has been negotiated
by the Parties in good faith.
This letter agreement constitutes a written agreement by and among the Parties
as set forth in Clause 25.8 of the Agreement.
All terms used but not defined herein shall have the meaning set forth in the
Agreement. Clause 26 of the Agreement shall apply also to this letter agreement.
Yours faithfully on behalf of Spirit,
/s/ Sam J. Marnick
Mrs. Sam. J. Marnick
