subject to the vesting requirements described in Section 4.02 and Section 4.03
(shares granted subject to vesting requirements are referred to herein as
"Restricted Shares"). Participation by a Participant in any grant of Shares

Plan and in a grant of Shares under the Plan. The Shares may be either
previously issued Shares that have been reacquired by the Company or authorized
but unissued Shares, as the Board of Directors shall from time to time
determine, in its Sole Discretion. If any Participant's interest in Shares
granted under the Plan terminates, any Shares in which the Participant has no
further interest shall again become available to be granted under the Plan.

     Section 4.02. One Year Service Requirement. If a Participant ceases to
serve as a Director prior to the first anniversary of the date of grant of any
Restricted Shares, any such Restricted Shares in which such Participant has not
theretofore acquired an unrestricted interest pursuant to Section 4.03 shall, on
the date such Participant ceases to be a Director, be forfeited to the Company
without any payment therefor.

     A.   A Participant granted Restricted Shares by the Company shall acquire
          an unrestricted interest in those Restricted Shares only as follows:

          1. Upon a Liquidity Event (or deemed Liquidity Event, in accordance
          with Section 4.03.B.3), if the Positive Return Condition is satisfied,
          each Participant holding Restricted Shares shall acquire an
          unrestricted interest in the number of Restricted Shares held by such
          Participant, subject to Section 4.03.B., equal to (1) the Applicable
          Percentage of the total number of Restricted Shares granted to such
          Participant under the Plan, less (2) the total

                                      -5-

<PAGE>

          number of Restricted Shares, if any, in which such Participant has
          previously acquired an unrestricted interest under the Plan.

          2. Following a Qualified Public Offering, if the QPO Positive Return
          Condition is satisfied on any Measurement Date, each Participant
          shall, subject to Section 4.03.B., acquire an unrestricted interest in
          all Restricted Shares then held by such Participant.

     B.   Operating Rules. The following rules also shall apply.

          1.   Future Liquidity Events. Following the occurrence of a Liquidity
               Event, the provisions of this Section 4.03 may again be applied
               to such Participant upon a later Liquidity Event to determine
               whether the Participant may acquire an interest in any remaining
               Restricted Shares granted to the Participant under the Plan.

          2.   Forfeiture Following Termination. If, on the fifth anniversary of
               the date on which a Participant ceases to serve as a Director,
               such Participant continues to hold Restricted Shares in which he
               or she has not acquired an unrestricted interest, any interest in
               such Restricted Shares shall terminate and such Restricted Shares
               shall be forfeited to the Company without any payment therefor.

          3.   Ten-Year Limit. On the 10th anniversary of the Closing Date, if
               any Participant(s) continue to hold Restricted Shares in which
               they have not acquired an unrestricted interest (i.e., such
               Restricted Shares have not been forfeited to the Company), the
               provisions of this Section 4.03 shall be applied as if Onex sold
               the remainder of its equity investment in the Company on such
               date for consideration equal to Market Value, and a final
               determination shall be made at that time whether the
               Participant(s) will acquire an interest in such Restricted
               Shares.

          4.   Termination of Interest in Restricted Shares. Upon disposition by
               Onex of all of its equity interest or remaining equity interest
               in the Company or upon the occurrence of a deemed disposition in
               accordance with Section 4.03.B.3 above, any Participant 's
               interest in Restricted Shares in which he or she has not acquired
               an unrestricted interest on or prior to the date of such
               disposition or deemed disposition shall terminate and shall be
               forfeited to the Company without any payment therefor.

     Section 4.04. Dividends. Dividends declared by the Board of Directors with
respect to Shares shall, with respect to any Restricted Shares, be cumulated and
paid to the Participant only at the time, and to the extent that, the
Participant acquires an unrestricted interest in any such Restricted Shares in
accordance with this Article IV.

                                      -6-

<PAGE>

     Section 4.05. No Rights of Stockholder. Restricted Shares shall not be
subject to transfer or assignment, and a Participant shall not have the rights
of a stockholder in the Company with respect to any Restricted Shares unless and
until the Participant acquires an interest in such Restricted Shares in
accordance with this Article IV, provided that Participants shall, subject to
the Stockholders Agreement, be entitled to voting rights of a holder of the
Shares granted hereunder unless and until such Shares are required to be
forfeited to the Company.

     Section 4.06. Call Rights on Former Directors' Shares.

     A.   If a Participant ceases to serve as a Director (following such
          cessation, a "Former Director") prior to a Qualified Public Offering,

          right to require such Former Director (or, in the case of death or
          permanent disability, such Former Director's executor, personal
          representative or legal representative) to sell, by delivery of a
          written notice (the "Call Notice") to such Former Director (or, in the
          case of death or permanent disability, such Former Director's
          executor, personal representative or legal representative) within 180
          days after the date of the Call Event (the "Initial Call Period"), and
          such Former Director (or, in the case of death or permanent
          disability, such Former Director's executor, personal representative
          or legal representative) shall be required to sell, all of the Shares
          then held by such Former Director in which such Former Director has
          acquired an unrestricted interest (including any Shares then held by
          an Affiliate of such Former Director pursuant to a Transfer under
          Section 4.2(a)(i) of the Stockholders Agreement) at a price per Share
          equal to the Call Price.

     B.   If at any time, a Former Director acquires an unrestricted interest in
          additional Shares after the expiration of the Initial Call Period and
          prior to a Qualified Public Offering, then the Company shall have the
          right to require such Former Director (or, in the case of death or
          permanent disability, such Former Director's executor, personal
          representative or legal representative) to sell, by delivery of a Call
          Notice to such Former Director (or, in the case of death or permanent
          disability, such Former Director's executor, personal representative
          or legal representative) within 90 days after the date of such
          acquisition (a "Subsequent Call Period"), and such Former Director
          (or, in the case of death or permanent disability, such Former
          Director's executor, personal representative or legal representative)
          shall be required to sell, all of the Shares then held by such Former
          Director in which such Former Director has acquired an unrestricted
          interest (including any Shares then held by an Affiliate of such
          Former Director pursuant to a Transfer under Section 4.2(a)(i) of the
          Stockholders Agreement) at a price per Share equal to the Call Price.

     C.   The closing of any purchase of Shares by the Company pursuant to this
          Section 4.06 shall take place at the principal office of the Company
          within 15

                                      -7-

          days after the expiration of the Call Period or Subsequent Call
          Period, as applicable, as the Company shall specify to such Former
          Director (or, in the case of death or permanent disability, such
          Former Director's executor, personal representative or legal
          representative) in writing. At such closing, such Former Director (or,
          in the case of death or permanent disability, such Former Director's
          executor, personal representative or legal representative) shall
          deliver to the Company certificates and/or other instruments
          representing, together with stock or other appropriate powers duly
          endorsed with respect to, the Shares, free and clear of all liens,
          encumbrances or other restrictions (other than pursuant to securities
          laws or the Stockholders Agreement), against payment by the Company of
          the purchase price for the Shares in cash by delivery of a certified
          check payable to such Former Director (or, in the case of death, such
          Former Director's estate). Notwithstanding the foregoing, if the
          payment of all or any portion of the purchase price is not permitted
          to be made at the closing by the terms any credit agreement(s)
          relating to the Company's senior debt (collectively, the "Credit
          Agreement"), or the payment would cause a Default or an Event of
          Default (as such terms are defined in any Credit Agreement), then that
          portion of the purchase price shall instead become a subordinated
          obligation of the Company (a "Subordinate Obligation"); the
          Subordinate Obligation shall not be payable during the continuance of
          a Default or an Event of Default (as defined in any Credit Agreement)
          or if such payment would not otherwise be permitted by any Credit
          Agreement or would result in a Default or an Event of Default (as
          defined under any Credit Agreement). The Subordinate Obligation shall
          be payable on the earlier to occur of (i) one day after the closing
          date of a complete refinancing of the Company's senior debt and (ii)
          receipt by the Company of the written approval of its senior lenders
          to pay the principal and interest on the obligation in full. The
          Subordinate Obligation shall accrue interest at the weighted average
          rate applicable from time to time on the Company's senior debt. The
          Company shall pre-pay the amount of any Subordinate Obligation,
          together with accrued and unpaid interest, as and when it is permitted
          to do so without Default (as defined in any Credit Agreement) or
          creating an Event of Default (as defined in any Credit Agreement)
          under any Credit Agreement, provided, that if there is more than one
          Subordinate Obligation outstanding, the Company shall make
          pre-payments on each Subordinate Obligation in the proportion that the
          outstanding amount thereof (including accrued and unpaid interest)
          bears to the aggregate outstanding Subordinate Obligations (including
          accrued and unpaid interest).

     D.   If and to the extent the Company does not deliver a Call Notice within
          the Call Period or Subsequent Call Period, as applicable, or if the
          purchase of all Shares subject to the Call Notice does not occur at
          the scheduled closing date through the fault of the Company, then the
          Company's right to purchase such Shares pursuant to this Section 4.06
          shall terminate.

                                    AGREEMENT

     THIS AGREEMENT (the "Agreement") is made as of this 30th day of June 2005,
by and between ONEX PARTNERS MANAGER, L.P. a Delaware limited partnership
("Onex") and Spirit AeroSystems, Inc., a Delaware corporation (the "Company").

                            - PRELIMINARY STATEMENT -

     Onex Partners, LP, a Delaware limited partnership ("Onex Partners") and an
affiliate of Onex, along with various other affiliates, own a majority interest
in the common stock of the Company as a result of providing equity funding for
the Company's acquisition of its business from The Boeing Company pursuant to an
asset purchase agreement dated February 22, 2005;

     The Company desires to avail itself of certain resources, advice and
assistance of, and available to, Onex as set forth herein; and

     Onex is willing to provide such services to the Company and the Company is
willing to engage Onex on the terms and conditions set forth in this Agreement.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein set forth, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

                                  - AGREEMENT -

                                    ARTICLE 1

                                    SERVICES

     SECTION 1.1 ENGAGEMENT OF ONEX. The Company hereby engages Onex to provide
the services delineated in Section 1.2 below (the "Services") and Onex agrees to
provide such Services as and when requested, in accordance with the terms and
conditions set forth herein.

     SECTION 1.2 SECTION 1.2 SERVICES. Subject to the requirements of the
Company's Special Security Agreement dated August 10, 2005 ("SSA"), and subject
to the oversight of the Company's Government Security Committee ("GSC"), during
the Term (as defined herein) Onex shall provide the Company with non-binding
guidance and advice with such matters as may be reasonably requested from time
to time by the Company or its affiliates. Without limiting the generality of the
foregoing, Onex may provide the Company, at the Company's request, with such
resources, advice and assistance as is necessary or desirable in order for the
Company to determine, at its sole discretion, its overall strategic and
financial planning, commercial initiatives, and debt and equity financings (the
"Services"). From time to time thereafter, subject to the requirements of the
SSA, including but not limited to the approval of the

<PAGE>

GSC, the Board of Directors of the Company may request Onex and/or its
affiliates to provide additional services in addition to those contemplated
herein. However, the Company and Onex both acknowledge and agree that the
services referred to above do not include investment banking or financial advice
in connection with business acquisitions.

     SECTION 1.3 SOURCING OF SERVICES. For purposes of this Agreement, Onex may
at its discretion seek the services of independent third parties, with such
services being paid for by the Company, so long as the Company approves of such
services in advance.

                                    ARTICLE 2

                                      TERM

     SECTION 2.1 TERM. Subject to the terms herein, the term of this Agreement
shall commence on June 30, 2005 (the "Effective Date") and shall continue for an
initial eight-year term (the "Term"). Thereafter, subject to the approval of the
GSC, the Agreement may be renewed automatically for successive one-year periods.

     SECTION 2.2 TERMINATION OF THIS AGREEMENT. This Agreement shall terminate
by mutual agreement of the parties, signed and in writing, or at such time as
Onex Partners, or any of its affiliates, individually or in the aggregate, no
longer hold more than 5% of the outstanding shares of Common Stock.

     SECTION 2.3 CONSEQUENCES OF TERMINATION. Within 30 days after any
termination of this Agreement, the Company shall remit to Onex any accrued but
unpaid Service Fee (as defined herein) and reimbursable expenses.

                                    ARTICLE 3

                                  COMPENSATION

     SECTION 3.1 COMPENSATION.

          (a) COMPENSATION. For and in consideration of the Services, the
Company shall pay Onex a fixed annual fee of $3,000,000 per year (the "Service
Fee").

          (b) PAYMENT. The Company shall pay to Onex the Service Fee, in
arrears, on a quarterly basis, on the last day of March, June, September and
December of each year commencing September, 2005. All payments to be made by the
Company to Onex shall be immediately available funds, unless the parties agree
otherwise. In the event the Company is unable to pay the Service Fee (or any
portion thereof) due to restrictions contained in any revolving credit or term
loan agreement to which it is a party (as a borrower or otherwise), the Service
Fee (or such portion) shall not be paid, but shall accrue until such payment is
no longer restricted, at which time the accrued but unpaid Service Fee (or such
portion) shall be paid to Onex. In the event the Company fails to pay the
Service Fee (or any portion thereof) to Onex as and when due in accordance with
the first two sentences of this paragraph (including by virtue of any deferral
required by the foregoing sentence), it shall be required to pay Onex interest
on all such unpaid amounts at an annual interest rate from time to time
announced by Citibank as its

                                       2

<PAGE>

"Prime Rate" of interest used by it as a reference rate for commercial loans in
United States dollars adjusted on a daily basis for changes in that rate. The
Service Fee (including any portion deferred pursuant to the third sentence of
this paragraph) and any interest due thereon shall accrue on a daily basis from
and after July 1, 2005, and each quarterly payment shall be in respect of the
three-month period ended on the day payment is due or for such shorter period
within such three months during which the Agreement was in effect. Any amounts
due to Onex under this Agreement may, at Onex's sole discretion and direction,
be payable to one or more affiliates of Onex.

     SECTION 3.2 EXPENSES. All reasonable, ordinary and necessary expenses,
including but not limited to travel, fees for external consultant, advisors and
professionals and other direct out-of-pocket expenses incurred by Onex or its
affiliates in the performance of the Services shall be paid or reimbursed by the
Company. The Company shall, within 30 days after the receipt of an invoice from
Onex, reimburse Onex in full.

                                    ARTICLE 4

                                  MISCELLANEOUS

     SECTION 4.1 RELATIONSHIP OF PARTIES. The parties acknowledge and agree that
each is a separate business entity, that each has its own management, and
separate policies and procedures, and that nothing contained herein shall
constitute the delegation of authority and power to Onex to manage and/or
control the Company's business. The parties further acknowledge and agree that
the relationship established between the two is that of independent contractors
and is not a joint venture or partnership and that the Services to be performed
are intended to be merely auxiliary to and supportive of the Company's business.
Neither Onex nor its employees shall be considered employees of the Company.
Onex shall have no right to enter into any contract or undertaking in the name
of or for the account of the Company, nor to assume or create any obligation of
any kind, express or implied, on behalf of the Company, without the prior
written consent of the Company.

     SECTION 4.2 INDEMNIFICATION. The Company agrees to indemnify, defend and
hold harmless, Onex, its affiliates, directors, officers and/or employees from
and against any and all loss, liability, suits, claims, costs, damages and
expenses (including reasonable attorney fees) arising from their performance
hereunder, except where Onex's actions or omissions rise to the level of gross
negligence or willful misconduct. Onex assumes no responsibility to the Company
hereunder other than as expressly set forth herein.

     SECTION 4.3 NOTICE. Any notice, request, consent or communication
(collectively "Notice") sent under this Agreement shall be effective only if it
is in writing and (a) personally delivered, (b) sent by certified or registered

received by the intended recipient.

     SECTION 4.4 WAIVER. The failure of either of the parties to insist, in any
one or more instances, upon performance of any of the terms or conditions of
this Agreement, shall not be construed as a waiver or relinquishment of any
rights granted hereunder or the future performance of any such term, covenant or
condition.

     SECTION 4.5 COMPLETE UNDERSTANDING. This Agreement constitutes the complete
understanding among the parties with respect to the matters set forth herein. No

all aspects of this Agreement, irrespective of the fact that one or more of the
parties now is or may become a resident of a different state, or that the one or
more of the parties now or hereafter locates its principal office outside the

YORK SHALL HAVE EXCLUSIVE JURISDICTION OVER THIS AGREEMENT AND SPECIFICALLY
WAIVE ANY CLAIMS WHICH THEY MAY HAVE THAT INVOLVE JURISDICTION OR VENUE,
INCLUDING BUT NOT LIMITED TO FORUM NON CONVENIENS. Service of process for any
claim that arises under this Agreement shall be valid if made in accordance with
the notice provisions set forth in Section 4.3 of this Agreement. If service of
process is made as aforesaid, the party served agrees that such service shall
constitute valid service, and specifically waives any objections the party
served may have under any state or Federal law or rule concerning service of
process. Service of process in accordance with this Section 4.6 shall be in
addition to and not to the exclusion of any other service of process method
legally available.

any one or more of this Agreement's provisions are invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
