Under

Non-Employee Director

Stock Program

Section 1. Purpose and Effect.

(a)This Appendix A to the Non-Employee Director Stock Program (“Program”) under the Orbital ATK, Inc. 2015 Stock Incentive Plan (“Plan”) authorizes the deferral of income that would otherwise be recognized upon the lapse of restrictions applicable to Restricted Stock Awards under the Plan.

(b)In accordance with the rules set forth in this Appendix A, Directors may waive their rights to receive Restricted Stock Awards under the Program and instead receive an equal number of deferred Restricted Stock Units in a deferred restricted stock unit account (“Deferred Restricted Stock Unit Account”) by making a timely deferral election in accordance with the provisions of this Appendix A (“Deferral Election”).

Section 2. Deferral Election.

(a)A Non-Employee Director may make a Deferral Election in accordance with this Appendix A on or before December 31 of the year preceding the date of the Annual Meeting at which the Restricted Stock Award is to be made under the Program. If a Director’s initial election to the Board does not occur at an Annual Meeting, the Director may make a Deferral Election within 30 days after the date of being elected to the Board with respect to the Restricted Stock Award that would otherwise be granted as of the date of the next Annual Meeting. Directors first elected to the Board at an Annual Meeting are not eligible to make a Deferral Election with respect to the Restricted Stock Award for the year of election to the Board. A Director whose initial election to the Board does not occur at an Annual Meeting may make a Deferral Election with respect to the Restricted Stock Award that would otherwise be granted upon initial election to the Board no later than 30 days after first being elected to the Board provided that such election occurs prior to commencement of service as a Director.

(b)A Deferral Election made pursuant to this Section 2 shall be timely made in writing and shall specify the time of payment in accordance with the rules for payment under Section 4 of this Appendix A. Any Deferral Election made pursuant to this Section 2 shall be irrevocable and shall apply to 100%, and not less than 100%, of the shares subject to the Restricted Stock Award. A Deferral Election will be applicable to all future Restricted Stock Awards unless and until the Deferral Election is rescinded in writing by the Non-Employee Director delivered to the Company (to the attention of the Corporate Secretary) by the time prescribed in Section 2(a) of this Appendix A.

(c)Deferral Elections and beneficiary designations made pursuant to this Appendix A must be made in writing on forms substantially similar to the forms set forth in Exhibits 1 and 2 to this Appendix A, and shall be subject to such other procedural rules as the Committee may establish. The election forms must be received by the Company (to the attention of the Corporate Secretary) by the time prescribed in Section 2(a) of this Appendix A.

Section 3.Deferred Restricted Stock Unit Account. A Deferred Restricted Stock Unit Account shall be established and maintained for each Director who has made a Deferral Election, subject to the following rules:

(a)For each share of Restricted Stock deferred, a Restricted Stock Unit shall be credited to the Director’s Deferred Restricted Stock Unit Account as of the date the Restricted Stock Award otherwise would have been granted. The Restricted Stock Units shall be subject to forfeiture during the Restricted Period specified in Section 2.4 of this Program and any Deferred Restricted Stock Units in the Account shall be forfeited if the vesting requirement is not satisfied prior to the Payment Date specified in Section 4 of this Appendix A. No Shares will be issued to a Director until the Payment Date, as specified in Section 4 of this Appendix A.

(b)On each payment date for any cash dividends paid on Shares of the Company, the Company shall pay to each Director an amount equal to the cash dividends that would be payable by the Company on a number Shares equal to the number of Restricted Stock Units in the Director’s Deferred Restricted Stock Unit Account as of such payment date. Such amounts shall be paid directly to each Director in cash and shall not be eligible for deferral under this Program.

(c)The number of units credited to the Director’s Deferred Restricted Stock Unit Account shall be appropriately and equitably adjusted to reflect any change in the outstanding Shares of the Company in the event of any dividend or other distribution, recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase or exchange of Shares or other securities of the Company, or other similar corporate transaction or event affecting the Shares.

(d)Directors who elect to make a Deferral Election in accordance with this Appendix A will have no rights as stockholders of the Company with respect to Restricted Stock Units credited to their Deferred Restricted Stock Unit Accounts.

Section 4.Payment of Deferred Amounts.

(a)Payment of the aggregate value of the Restricted Stock Units in the Director’s Account shall be made in a lump sum at the time specified by the Director in his or her Deferral Election (the “Payment Date”), but in no event later than the later of the last day of the calendar year in which the Payment Date occurs or the 15^th day of the third calendar month following the Payment Date. Notwithstanding the foregoing, in all events payment of a Director’s entire Deferred Restricted Stock Unit Account, subject to the expiration of the Restricted Period, shall be made in a lump sum as soon as administratively feasible following the termination of the Director’s service on the Board for any reason, but in no event later than the later of the last day of the calendar year in which such termination of service occurs or the ninetieth day following such termination of service. The date of retirement or termination of service of a Director shall constitute the Payment Date for purposes of this Appendix A.

(b)Payment of the aggregate value of the Restricted Stock Units in a Director’s Deferred Restricted Stock Unit Account shall be made solely in the form of Shares. As promptly as practicable following the Payment Date, the Company shall pay to the Director a number of Shares equal to the number of Restricted Stock Units in the Director’s Account on the Payment Date. The delivery of the Shares shall be subject to and contingent upon the completion of any registration or qualification of the Shares under any federal or state law or governmental rule or regulation that the Company, in its sole discretion, determines to be necessary or advisable.

Section 5.Payment in Event of Death of Non-Employee Director. A Director shall submit to the Company a written designation of the beneficiary or beneficiaries to whom payment of the aggregate value of the Director’s Deferred Restricted Stock Unit Account shall be made in the event of the Director’s death. Beneficiary designations must be in writing on forms substantially similar to the form set forth in Exhibit 2 to this Appendix A and shall be subject to such other procedural rules as the Committee may establish. Beneficiary designations shall become effective only when received by the Company. If no beneficiary designation form is on file with the Company on the date of death of the Director, or if no beneficiary is living on the Payment Date, the Director’s Account shall be distributed to the representative of the Director’s estate. Payment to the Director’s designated beneficiary shall be made in the form of Shares in accordance with the provisions of this Program.

Section 6.Unfunded and Unsecured Program. The Director’s Deferred Restricted Stock Unit Account shall be hypothetical in nature and shall be maintained for bookkeeping purposes only. The Deferred Restricted Stock Unit Account shall be unfunded for tax purposes and no provision shall be made at any time with respect to segregating assets of the Company for payment of amounts in the Deferred Restricted Stock Unit Account. The obligation of the Company to make payments pursuant to this Appendix A constitutes an unsecured but legally enforceable promise of the Company to make such payments.

Section 7. Construction. This Appendix A is intended to comply with section 409A of the Internal Revenue Code of 1986, as amended. Any Deferral Election that is inconsistent with Code section 409A shall not be effective.
