This cash-based long-time incentive award agreement (the “Agreement”) is made as of ______, 202_ (the “Effective Date”), between Ducommun Incorporated, a Delaware corporation (the “Corporation”), and ________ (“Award Holder”).

This Agreement is subject to and governed by the terms of the Amended and Restated 2020 Stock Incentive Plan (the “Plan”).

1.Grant. The Corporation hereby grants to the Award Holder an award (the “Award”) with a target value (if the Corporation achieves the target level performance goals described in Exhibit A attached hereto) of $____________ (the “Target Award”), subject to certain adjustments as described herein. The Award granted hereunder represents the right to receive a payment in cash based upon the percentage of the Target Award earned, subject to the conditions set forth in this Agreement and the Plan.

2.Definitions. Unless the context clearly indicates otherwise, and subject to the terms and conditions of the Plan as the same may be amended from time to time, the following terms, when used in this Agreement, shall have the meanings set forth in this Section 2.

        “Common Stock” shall mean the Common Stock, $.01 par value, of the Corporation or such other class of shares or other securities as may be applicable pursuant to the provisions of Sections 4 and 9 of this Agreement.

“Subsidiary” shall mean a corporation or other form of business entity more than 50% of the voting shares of which is owned or controlled, directly or indirectly, by the Corporation and which is designated by the Committee for participation in the Plan by the key employees thereof.

    3.    Vesting. The Award shall vest at the end of the 3-year performance period, beginning as of January 1, 202_ and ending on December 31, 202_ (the “Performance Period”). The vesting of the Award shall be based upon the Corporation achieving during the last year of the Performance Period, that level of revenue as set forth in Exhibit A as approved by the Committee at the commencement of the Performance Period. Following the end of each fiscal year of the Performance Period and the collection of relevant data necessary to determine the extent to which the performance goals set forth in Exhibit A have been satisfied, the Committee will determine: (a) the amount of revenue that was achieved by the Corporation during the Performance Period relative to the level of revenue approved by the Committee, and (b) the percentage of the Target Award earned as a result thereof for the Performance Period (the “Earned Award”). The Earned Award shall vest (and become the “Vested Award”) as of the last day of the Performance Period, subject to the continued employment of the Award Holder by the Corporation through such date. The Committee shall

make the determination set forth herein in its sole discretion. The level of achievement of revenue shall be evidenced by the Committee’s written certification. For the avoidance of doubt, any portion of the Target Award that does not vest in accordance with the forgoing shall expire without consideration at the end of the Performance Period.

4.    Settlement of Vested Award. Upon the vesting of all or a portion of the Award, the Vested Award shall be paid to the Award Holder in cash, subject to any required tax withholding obligations, upon the Committee’s written certification as set forth in Section 3. No shares of Common Stock shall be issued with respect to the Award. The Award Holder shall not acquire or have any rights as a shareholder of the Corporation by virtue of this Agreement (or the Award evidenced hereby). Notwithstanding the foregoing, the Award Holder may elect, on a form and in a manner prescribed by the Corporation, to defer any payment of Vested Award, provided that any such deferral of payment must comply with any applicable requirements of Section 409A of the Code.

5.        Termination. If the Award Holder’s employment with the Corporation or a Subsidiary terminates before the end of the Performance Period for any reason, except as provided in this Section 5 or as determined by the Committee in its sole and absolute discretion, then the Award will be forfeited and cancelled and surrendered to the Corporation without payment of any consideration, effective on the date of the Award Holder’s termination of employment. Upon the termination of the Award Holder’s employment with the Corporation or a Subsidiary as a result of the Award Holder’s death or “permanent disability” (as defined herein) the Restricted Stock Units shall become fully vested on the date of such death or “permanent disability”. As used herein, the term “permanent disability” shall mean the date on which the Award Holder has not worked or been able to work due to physical or mental incapacity for a period of one hundred eighty (180) consecutive days.

6.     Reserved.

        7.     No Right to Continued Employment.

    8.    Reserved.

Upon any attempt to so transfer, assign, pledge, hypothecate or otherwise dispose of this Agreement, this Award or any other right or privilege granted hereby contrary to the provisions hereof, this Agreement, this Award and all of such rights and privileges shall immediately become null and void, provided however, that the Award Holder may transfer an Award to any “family member” (as such term is defined in Section A.1(a)(5) of the General Instructions to Form S-8 under the

Securities Act of 1933, as amended (“Form S-8”)), to trusts solely for the benefit of such family members and to partnerships in which such family members and/or trusts are the only partners; provided that the transfer is pursuant to a gift or a domestic relations order to the extent permitted under the General Instructions to Form S-8 and provided further, that such transferee acknowledges and agrees that the Award remains subject to all of the terms and conditions of this Agreement and the Plan.

    12.    Other Programs. Nothing contained in this cash-based long-time incentive award agreement shall affect the right of the Award Holder to participate in and receive benefits under and in accordance with the then current provisions of any pension, insurance, profit-sharing or other employee benefit plan or program of the Corporation or of any Subsidiary of the Corporation.

    13.    The Plan. The Award hereby granted is subject to, and the Corporation and Award Holder agree to be bound by all of the terms and conditions of the Plan as the same may be amended from time to time in accordance with the terms thereof, but no such amendment may adversely affect the Award Holder’s rights under this Agreement.

    16.    Consideration. The consideration for the rights and benefits conferred on Award Holder by this Award are the services rendered by the Award Holder after and not before the grant of this Award.
