NOW, THEREFORE, in consideration of the promises and mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

a.Termination of Employment. Mr. Johnson confirms that his employment with D3 has ended, including all positions Mr. Johnson holds or has held with the, effective as of the Termination Date. Except for the payments described in this Agreement, Mr. Johnson acknowledges that he has received all compensation and employee benefits to which he is otherwise entitled.

b.Salary Compensation through the Termination Date. Regardless of whether Mr. Johnson executes this Agreement and to the extent that Mr. Johnson has not already received payment, D3 shall pay Mr. Johnson all unpaid base compensation to which he is otherwise entitled at his current rate and status (“Current Base Salary”) as of the Termination Date, for all time worked through the Termination Date, in accordance with D3’s generally applicable policies and procedures.

2.Severance Benefits. Pursuant to the terms of the Employment Agreement and in exchange for execution of this Agreement, D3 shall provide to Mr. Johnson the following Severance Benefits:

a.Severance Pay. D3 shall provide Mr. Johnson with severance pay (“Severance Pay”) equal to Three Hundred Thirty-Five Thousand Three-Hundred Eighty Dollars ($335,380.00), less applicable withholdings, which is the equivalent of twelve (12) months of his Base Salary for the same period. Severance Pay shall be payable in equal installments, according to the Company’s normal payroll policies, commencing on the first practical pay period date following the occurrence of all of the following: (1) Mr. Johnson’s termination of employment; (2) Mr. Johnson’s execution of this Agreement; and (3) expiration of the revocation period described in Section 4.f. without Mr. Johnson having revoked this Agreement.

b.Stock. Mr. Johnson acknowledges that as a result of his termination, in accordance with the terms of his Restricted Stock Agreements (RSAs), he will forfeit any and all rights he has or ever has had in the 3,000 shares and 14,291 shares of stock granted to him on 02/11/13 and 05/13/14, respectively.

Such coverage shall be provided in accordance with terms of the Health Plan(s) as may exist or may be amended from time to time. Thereafter, if Mr. Johnson elects to continue COBRA coverage, he will be responsible for payment of the normal, full COBRA premium for the remainder of any coverage continuation thereafter.

e.All payments made under this Agreement, in any form, shall be subject to such withholdings for taxes, including income and employment taxes that D3 determines should be deducted or withheld under applicable law.

h.D3’s Retirement Plan(s). Mr. Johnson may have vested interests in an D3-sponsored 401(k) plan or other retirement or deferred compensation plan(s). Mr. Johnson’s interests in said plans shall be paid pursuant to the terms of those plans, and nothing in this Agreement shall modify or override those terms. Mr. Johnson’s right to participate in those plans shall terminate on the Termination Date. The amounts paid pursuant to Section 1(c) shall not constitute wages for purposes of the plans.

i.Section 409 (A). This Agreement shall at all times be administered and the provisions of this Agreement shall be interpreted consistent with the requirements of Section 409A. In the event that any provision of this Agreement does not comply with the requirements of Section 409A, D3, in exercise of its sole discretion and without consent of Mr. Johnson, may amend or modify this Agreement in any manner to the extent necessary to meet the requirements of Section 409A.

If Mr. Johnson breaches or threatens to breach any obligations under this Agreement, D3 and Released Parties may experience irreparable harm for which money damages will not provide an adequate remedy. D3 or any Released Party may seek appropriate equitable relief in addition to legal relief. Furthermore, in the event of a breach by Mr. Johnson, the Parties expressly agree that D3 shall be relieved of any further obligation to make any payments or provide any benefits required under this Agreement and the Severance Pay paid under Section 1 hereof shall, upon demand by D3, be repaid by Mr. Johnson within ten (10) days of such demand.

This remedy is in addition to, and shall not superseded or replace, the fee recovery provisions of Section 2.e. by which the Released Parties shall recover attorneys’ fees and costs for the defense of any action or claims brought in violation of the terms of Paragraph 2.

All parties hereto specifically waive any entitlement that they may have to trial by jury. The parties hereto agree that any service of process may be made by mail to the principal place of business or residence of each party and this constitutes proper service of process under applicable law in any action or proceeding under or in respect of this Agreement.

Dated: October 2, 2014            /s/ Richard L. Johnson_______________

Richard L. Johnson

For the purposes set forth in the LMI Aerospace, Inc. ("Company") 2005 Long-Term Incentive Plan, as the same may be amended from time to time (the "Plan"), you have been determined to be an Eligible Person and have been awarded by the Committee Seventeen Thousand Two Hundred Ninety-one (17,291) Stock Units (the "Stock Units"), which award (the "Award") is subject to and conditioned upon your acceptance of this Restricted Stock Unit Award Agreement (the "Agreement").

(a)You shall have no rights as a shareholder of the Company, no dividend rights (except as expressly provided in paragraph 5(b) with respect to Dividend Equivalent Rights) and no voting rights, with respect to the Stock Units or any Shares underlying or issuable in respect of such Restricted Stock Units until such Shares are actually issued to and held of record by you. No adjustments will be made for dividends or other rights of a holder for which the record date is prior to the date of issuance of the stock certificate or book entry evidencing such Shares.

(b)    As of any date that the Company pays an ordinary cash dividend on its Common Stock, the Company shall credit you with a dollar amount equal to (i) the per share cash dividend paid by the Company on its Common Stock on such date, multiplied by (ii) the total number of Restricted Stock Units (with such total number adjusted pursuant to Section 4 of the Plan) subject to the Award that are outstanding immediately prior to the record date for that dividend (a “Dividend Equivalent Right”). Any Dividend Equivalent Rights credited pursuant to the foregoing provisions of this paragraph 5(b) shall be subject to the same vesting, payment and other terms, conditions and restrictions as the original Stock Units to which they relate; provided, however, that the amount of any vested Dividend Equivalent Rights shall be paid in cash. No crediting of Dividend Equivalent Rights shall be made pursuant to this paragraph 5(b) with respect to any Stock Units which, immediately prior to the record date for that dividend, have either been paid pursuant to paragraph 6 or terminated pursuant to paragraph 4.

6.Timing and Manner of Payment of Stock Units. On or as soon as administratively practical following the termination of the Restricted Period (whether by the expiration or earlier termination thereof as provided in paragraph 3) (the “Vesting Date”) (and in all events not later than two and one-half (2 1/2) months after such vesting event), the Company shall deliver to you a number of Shares (either by delivering one or more certificates for such Shares or by entering such Shares in book entry form, as determined by the Company in its discretion) equal to the number of Restricted Stock Units subject to this Award that vest on the applicable Vesting Date and cash equal to the Dividend Equivalent Rights, less any tax-related items deemed by the Company to be an appropriate charge to you even if technically due by the Company as further set forth in paragraph 9, unless such Restricted Stock Units terminate prior to the given Vesting Date pursuant to Section 4. The Company’s obligation to deliver Shares or otherwise make payment with respect to vested Restricted Stock Units is subject to the condition precedent that you or other person entitled under the Plan to receive any Shares with respect to the vested Restricted Stock Units deliver to the Company any representations or other documents or assurances required pursuant to Section 11(a) of the Plan. You shall have no further rights with respect to any Restricted Stock Units that are paid or that terminate pursuant to Section 4.

7.Beneficiary Designation. You may designate a beneficiary for each outstanding grant of Restricted Stock Units in the event of your death. If no beneficiary is designated or the beneficiary does not survive you, the award shall be made to your surviving spouse, or, if there is none, to your estate.

8.Restrictions on Transfer. During the Restricted Period, the Restricted Stock Units awarded to you pursuant to this Agreement shall not be sold, assigned, transferred or otherwise disposed of, or mortgaged, pledged or otherwise encumbered except as provided in this Agreement or in the Plan.

(a)Generally. You are ultimately liable and responsible for all taxes owed in connection with the Award, regardless of any action the Company or any of its subsidiaries takes with respect to any tax withholding obligations that arise in connection with the Award. Neither the Company nor any of its subsidiaries makes any representation or undertaking regarding the treatment of any tax withholding in connection with the grant or vesting of the Award or the subsequent sale of Shares after the Restricted Stock Units has vested. The Company and its subsidiaries do not commit and are under no obligation to structure the Award to reduce or eliminate your tax liability.

(i)delivering of a certified check payable to the Company, c/o the Corporate Secretary, at the address specified in Section 12, or such other address as the Company may from time to time direct; or

(ii)electing in writing to have the Company retain that number of Shares and/or any Dividend Equivalent Rights having a Fair Market Value equal to the minimum amount required to be withheld (rounded downward to the nearest whole Share in the case of an election to use Shares ) determined on the applicable payment date; or

(iii)    such other means as the Committee may permit;

provided, however, that if you do not elect the means by which you will satisfy your Tax Withholding Obligation prior to the date on which the amount of tax to be withheld is determined, the Company may satisfy this obligation by any means reasonable, including automatic deduction from your check (s) for compensation.

10.Registration. The Company currently has an effective registration statement on file with the Securities and Exchange Commission with respect to the Shares. The Company intends to maintain this registration but has no obligation to do so. If the registration ceases to be effective, you will not be able to transfer or sell shares even after the restrictions lapse unless exemptions from registration under applicable securities laws are available. Such exemptions from registration are limited and might be unavailable. You agree that any resale by you of Shares shall comply in all respects with the requirements of all applicable securities laws, rules and regulations (including, without limitation, the provisions of the Securities Act, the Exchange Act and the respective rules and regulations promulgated thereunder) and any other law, rule or regulation applicable thereto, as such laws, rules and regulations may be amended from time to time. The Company shall not be obligated to either issue the Shares or permit the resale of any shares following vesting, if such issuance or resale would violate any such requirements.

11.Limitation on Rights; No Right to Future Grants. By entering into this Agreement and accepting the Award, you acknowledge that: (a) the Plan is discretionary and may be modified, suspended or terminated by the Board at any time as provided in the Plan; (b) the grant of the Award is a one-time benefit and does not create any contractual or other right to receive future grants of awards or benefits in lieu of awards; (c) all determinations with respect to any such future grants, including, but not limited to, the times when awards will be granted, the number of shares of Common Stock or Stock Units subject to each award, the award price, if any, and the time or times when each award will be settled, will be at the sole discretion of the Company; (d) your participation in the Plan is voluntary; (e) the Award is not part of normal or expected compensation for any purpose, including without limitation for calculating any benefits, severance, resignation, termination, redundancy, end of service payments, bonuses, long-term service awards, pension or retirement benefits or similar payments; (f) the future value of the common stock subject to the Award is unknown and cannot be predicted with certainty; and (g) neither the Plan, the Award nor the issuance of the Restricted Stock Units or Shares confers upon you any right to any relationship with the Company or any subsidiary other than as expressly provided hereby or thereby.

12.Execution of Award Agreement. Please acknowledge your acceptance of the terms and conditions of the Award by signing the original of this Agreement and returning it to the Corporate Secretary of the Company at the principal corporate offices of the Company at 411 Fountain Lakes Blvd., St. Charles, Missouri 63301.

13.Governing Law. The validity, construction, and effect of this Agreement and regulations relating to this Agreement, shall be determined in accordance with the internal laws, and not the law of conflicts, of the State of Missouri.

14.Rights and Remedies Cumulative. All rights and remedies of the Company and you enumerated in this Agreement shall be cumulative and, except as expressly provided otherwise in this Agreement, none shall exclude any other rights or remedies allowed by law or in equity, and each of said rights or remedies may be exercised and enforced concurrently.

15.Headings. Headings are given to the sections and subsections of this Agreement solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction-or interpretation of this Agreement or any provision thereof.

16.Entire Agreement. This Agreement and the Plan constitute the entire agreement between the Company and you in respect of the subject matter of this Agreement, and this Agreement supersedes all prior and contemporaneous agreements between the parties hereto in connection with the subject matter of this Agreement. No officer, employee or other servant or agent of the Company, and no servant or agent of you is authorized to make any representation, warranty or other promise not contained in this Agreement. No change, termination or attempted waiver of any of the provisions of this Agreement shall be binding upon any party hereto unless contained in a writing signed by the party to be charged.

17.Successors and Assigns. At the option of the Company, the rights of the Company under this Agreement may be transferable to any one or more persons or entities, and all covenants and agreements hereunder so transferred shall inure to the benefit of, and be enforceable by, such transferees.
