of any other actual or publicly threatened solicitation of proxies by or on behalf of any person other than the Board will be deemed to be an Incumbent Director; provided, further, that this Section 1.4(a) shall not be in effect until there are no Leonardo S.p.A “Proxy Holders” (as defined in the Proxy Agreement (as such agreement may be as amended, restated, modified, or supplemented from time to time, the “Proxy Agreement”) by and between the Company, the Proxy Holders, the Stockholder, Leonardo – Societa per azioni and the United States Department of Defense) on the Board;

(b) any “person” (as such term is defined in Section 3(a)(9) of the Exchange Act and as used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act), becomes a “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 30% or more of the combined voting power of the Company’s then- outstanding securities eligible to vote for the election of the Board (“Company Voting Securities”); provided, however, that the event described in this paragraph (b) will not be deemed to be a Change in Control by virtue of the ownership, or acquisition, of Company Voting Securities: (A) by the Company, (B) by any employee benefit plan (or related trust) sponsored or maintained by the Company, (C) by any underwriter temporarily holding securities pursuant to an offering of such securities or (D) pursuant to a Non-Qualifying Transaction (as defined in paragraph (c) of this definition); or (E) by Leonardo S.p.A or any of its direct or indirect Subsidiaries;

(d) the consummation of a sale of all or substantially all of the Company’s assets (other than to Leonardo S.p.A or any of its direct or indirect Subsidiaries or an affiliate of the Company); or

(e) the Company’s stockholders approve a plan of complete liquidation or

dissolution of the Company.

Notwithstanding the foregoing, a Change in Control will not be deemed to occur solely because any person acquires beneficial ownership of more than 30% of the Company Voting Securities as a result of the acquisition of Company Voting Securities by the Company which reduces the number of Company Voting Securities outstanding; provided that if after such acquisition by the Company such person (other than Leonardo S.p.A or any of its direct or indirect Subsidiaries) becomes the beneficial owner of additional Company Voting Securities that increases the percentage of outstanding Company Voting Securities beneficially owned by such person, a Change in Control will then occur. For the avoidance of doubt, a completion of (i) an offering of the Company’s equity securities registered under the Securities Act of 1933, as amended, (ii) a direct listing of such securities on a national securities exchange and/or (iii) an exchange of 50% or more of the shares of common stock of the Company then outstanding for publicly traded equity securities of an entity or person not affiliated with the Company, will not constitute a Change in Control.

2.5 In the event of a claim by a Severed Employee as to the amount or timing of any payment or benefit, such Severed Employee shall present the reason for his or her claim in writing to the Plan Administrator.

Such Severed Employee (or his or her duly authorized legal representative) may, upon written request to the Plan Administrator, (a) review any documents pertinent to his claim, (b) review any Plan documents relevant to his claim and (c) submit in writing issues and comments in support of his position. Within sixty (60) days after receipt of a written appeal (unless special circumstances, such as the need to hold a hearing, require an extension of time, but in no event more than one hundred twenty (120) days after such receipt and provided that the

Plan Administrator notifies the claimant of the delay), the Plan Administrator shall provide a written ruling to the Severed Employee of the final decision. The final decision shall be in

writing and shall include specific reasons for the decision, written in a manner calculated to be understood by the claimant, and specific references to the pertinent Plan provisions on which the decision is based. If the Plan Administrator does not provide the Severed Employee with written notice within sixty (60) days after receipt of the request for review, the Severed Employee’s claim will be deemed denied.

2.6 Regardless of whether employment terminates due to a Qualifying CIC Termination or a Qualifying Non-CIC Termination, no Severed Employee shall be eligible to receive Severance Pay or other benefits under the Plan unless he or she (i) first executes a Release following such Severed Employee’s Severance Date and such Release becomes effective and has not been revoked by the Severed Employee by the Release Effective Date and (ii) complies with the Restrictive Covenants set forth in Section 5 hereof.

2.7 The Company shall be entitled to withhold from amounts to be paid to the Severed Employee hereunder any federal, state, or local withholding or other taxes which it is from time to time required by law to withhold.

2.8 The Plan is intended to comply with the requirements of Section 409A. For purposes of Section 409A, each payment made under the Plan will be treated as a separate payment. In no event may the Severed Employee, directly or indirectly, designate the calendar year of payment. Notwithstanding any provision of the Plan to the contrary, if necessary to comply with the restriction in Section 409A(a)(2)(B) of the Code concerning payments to Specified Employees, any payment on account of such Severed Employee’s separation from service that would otherwise be due hereunder within six months after such separation will nonetheless be delayed until the first business day of the seventh month following Severed Employee’s Severance Date and the first such payment will include the cumulative amount of any payments that would have been paid prior to such date if not for such restriction, together with interest on such cumulative amount during the period of such restriction at a rate, per annum, equal to the applicable federal short-term rate (compounded monthly) in effect under Section 1274(d) of the Code on the Severance Date. Notwithstanding anything contained herein to the contrary, the Severed Employee will not be considered to have terminated employment with the Company for purposes of Section 2.1 hereof unless he would be considered to have incurred a “separation from service” from the Company within the meaning of Section 409A. Any tax liability incurred by a Severed Employee under Section 409A of the Code will be solely the responsibility of the Severed Employee.

3. EXCISE TAXES.

3.1 Notwithstanding any other provision of the Plan, in the event that any portion or all of the Total Payments received or to be received by a Severed Employee would be subject (in whole or part), to the Excise Tax, then, after taking into account any reduction in the Total Payments provided in such other plan, arrangement or agreement due to the applicability of section 280G of the Code, the Severance Pay shall first be reduced, and the other benefits under the Plan shall thereafter be reduced, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax, but only if (A) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments) is greater than or equal to (B) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of

Excise Tax to which the Severed Employee would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments).

3.2 For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (i) no portion of the Total Payments shall be taken into account which, in the opinion of Tax Counsel, does not constitute a “parachute payment” within the meaning of section 280G(b)(2) of the Code (including by reason of section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall be taken into account which, in the opinion of Tax Counsel, constitutes reasonable compensation for services actually rendered, within the meaning of section 280G(b)(4)(B) of the Code, in excess

of the Base Amount (as defined in section 280G(b)(3) of the Code) allocable to such reasonable compensation, and (ii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Auditor in accordance with the principles of sections 280G(d)(3) and (4) of the Code.

4. PLAN ADMINISTRATION.

4.1 The Plan shall be interpreted, administered, and operated by the Plan Administrator, who shall have complete authority, in its sole discretion subject to the express provisions of the Plan, to interpret the Plan, to prescribe, amend and rescind rules and regulations relating to it, to designate Eligible Employees and to make all other determinations necessary or advisable for the administration of the Plan.

4.2 All questions of any character whatsoever arising in connection with the interpretation of the Plan, or its administration or operation shall be submitted to and settled and determined by the Plan Administrator in an equitable and fair manner in accordance with the procedure for claims and appeals described in Section 2.5 hereof. Any such settlement and determination shall be final and conclusive and shall bind and may be relied upon by the Company, each of the Severed Employees and all other parties in interest.

4.3 The Plan Administrator may delegate any of its duties hereunder to such person or persons from time to time as it may designate.

4.4 The Plan Administrator is empowered, on behalf of the Plan, to engage accountants, legal counsel (which may be the Company’s General Counsel or designee) and such other personnel as it deems necessary or advisable to assist it in the performance of its duties under the Plan. The functions of any such persons engaged by the Plan Administrator shall be limited to the specified services and duties for which they are engaged, and such persons shall have no other duties, obligations, or responsibilities under the Plan. Such persons shall exercise no discretionary authority or discretionary control respecting the management of the Plan. All reasonable expenses thereof shall be borne by the Company.

The obligations under this Section 5.1(a) will not terminate if Confidential Information ceases to be confidential by reason of the Eligible Employee’s wrongful disclosure.

on behalf of any other individual or commercial enterprise: (i) Solicit, induce, or assist any third party in Soliciting or inducing any individual or entity who is then (or was at any time within the preceding twelve (12) months) an employee, consultant, independent contractor, or agent of Company (collectively, “Covered Employee”) to leave the employment of the Company or cease performing services for the Company; (ii) hire or engage any Covered Employee; or (iii) Solicit, induce, or assist any third party in Soliciting or inducing any other person or entity (including, without limitation, any third-party service provider or distributor) to terminate its relationship with the Company or otherwise interfere with such relationship. This non- solicitation provision explicitly covers all forms of oral, written, or electronic communication, including, but not limited to, communications by email, regular mail, express mail, telephone, fax, instant message, and social media, including, but not limited to, Facebook, LinkedIn, Instagram, Twitter, and any other social media platform, whether or not in existence at the time of entering into the Plan. However, it will not be deemed a violation of this section if Eligible Employee merely updates Eligible Employee’s LinkedIn profile or connects with a Covered Employee on Facebook, LinkedIn, or other social media platform without engaging in any other substantive communication, by social media or otherwise, that is prohibited by this Section.

on behalf of any other individual or commercial enterprise (i) Solicit any Client to transact business with a Competitive Enterprise or to reduce or refrain from doing any business with the Company; (ii) transact business with any Client that would cause you to be a Competitive Enterprise or (iii) interfere with or damage any relationship between the Company and a Client.

(d) The grant of the Severance Pay provided herein and Eligible Employee’s agreement to the Restrictive Covenants are intended to be mutually dependent promises and, in the event Eligible Employee breaches or threatens to breach the Restrictive Covenants, then to the greatest extent permitted by applicable law: (i) Severance Pay that has not yet been paid shall cease to be payable and (ii) any Severance Pay that has been paid to Eligible Employee during

the twelve (12) months prior to Eligible Employee’s breach or threatened breach of the Restrictive Covenants shall be repaid to the Company for no consideration.

5.2 Immediately upon the Eligible Employee’s termination of employment for any reason, or upon Company’s request at any other time, Eligible Employee will deliver to Company all Company Property. Following Eligible Employee’s termination of employment, Eligible Employee shall not retain, copy, or remove (either physically or electronically) any

Company Property from Company premises, computers, or other electronic equipment or storage devices.

5.3 By participating in the Plan, each Eligible Employee agrees and acknowledges that Eligible Employee has carefully read and considered the Restrictive Covenants, and, having done so, agrees and acknowledges that the Restrictive Covenants limit Eligible Employee’s ability to engage in competition during the period provided for above. Eligible Employee expressly warrants and represents that these restrictions with respect to time and scope of activity are reasonable and necessary to protect the Confidential Information and the Company’s

business goodwill and competitive position.

6. PLAN MODIFICATION OR TERMINATION.

The Plan may be amended or terminated by the Board at any time; provided, however, that except as required by law, the Plan may not be amended or terminated in anticipation of a Change of Control or within two (2) years immediately following a Change in Control in a manner that would adversely affect the rights of Eligible Employees under the Plan without the express written consent of each Eligible Employee so affected. Following an Eligible Employee’s Qualifying Termination, no Plan termination or amendment shall adversely affect the rights of such Severed Employee under the Plan without such Severed Employee’s written consent.

7. GENERAL PROVISIONS.

7.1 Except as otherwise provided herein or by law, no right or interest of any Eligible Employee under the Plan shall be assignable or transferable, in whole or in part, either directly or by operation of law or otherwise, including without limitation, by execution, levy, garnishment, attachment, pledge or in any manner; no attempted assignment or transfer thereof shall be effective; and no right or interest of any Eligible Employee under the Plan shall be subject to any obligation or liability of such Eligible Employee. When a payment is due under the Plan to a Severed Employee who is unable to care for his affairs, payment may be made directly to his

legal guardian or personal representative.

7.2 If the Company is obligated by law or by contract (including an outstanding executive employment agreement) to pay severance pay, a termination indemnity, notice pay, or the like, or if the Company is obligated by law to provide advance notice of separation, then any Severance Pay paid to a Severed Employee hereunder shall be reduced by the amount of any such severance pay, termination indemnity, notice pay or the like, as applicable, and by the amount of any salary received by the Severed Employee after the Company provided notice of separation according to Section 7.4 hereof. For the avoidance of doubt, a Severed Employee who is party to an executive employment agreement shall (notwithstanding anything to the contrary in such employment agreement) receive the greater of (i) any amounts payable hereunder or (ii) any amounts payable under such employment agreement arising from termination. If an Eligible Employee is party to an employment agreement with the Company, with regard to any amounts payable under such employment agreement upon a termination of employment, notwithstanding any provisions of the Plan to the contrary, the time and form of payment provided under the employment agreement shall apply instead of the time and form of payment under the Plan to the extent necessary to comply with Section 409A.

7.3 Total Payments paid under the Plan will be subject to any clawback or recapture policy that the Company may adopt from time to time to the extent provided in such policy and, in accordance with such policy, may be subject to the requirement that the Total Payments be repaid to the Company after they have been distributed to an Eligible Employee.

7.4 All notices or other communications hereunder shall be in writing and shall be deemed to have been duly given (a) when delivered personally, (b) upon confirmation of receipt when such notice or other communication is sent by facsimile or electronic mail, (c) one day

after timely delivery to an overnight delivery courier, or (d) on the fifth day following the date of deposit in the United States mail if sent first class, postage prepaid, by registered or certified

mail. The address for the Company shall be as follows: Leonardo DRS, Inc., 2345 Crystal Drive, Suite 1000, Arlington, Virginia 22202. The address for each Eligible Employee shall be the address on file with the Company.

7.5 Neither the establishment of the Plan, nor any modification thereof, nor the creation of any fund, trust, or account, nor the payment of any benefits shall be construed as giving any Eligible Employee, or any person whomsoever, the right to be retained in the service of the Company, and all Eligible Employees shall remain subject to discharge to the same extent as if the Plan had never been adopted.

7.6 If any provision of the Plan shall be held invalid or unenforceable, such invalidity or unenforceability shall not affect any other provisions herein, and the Plan shall be construed and enforced as if such provisions had not been included.

7.7 The Plan shall be binding upon the heirs, executors, administrators, successors and assigns of the parties, including each Eligible Employee, present and future, and any successor to the Company. In the case of any transaction in which the Company’s successor would not by operation of law be bound by the Plan, the Company shall require such successor to the Company to expressly and unconditionally assume the Plan in writing and honor the obligations of the Company hereunder, in the same manner and to the same extent that the Company would be required to perform if no succession had taken place.

7.8 The headings and captions herein are provided for reference and convenience only, shall not be considered part of the Plan, and shall not be employed in the construction of the Plan. Whenever any words are used herein in the masculine gender, they shall be construed as though they were also used in the feminine gender in all cases where they would so apply, and, whenever any words are used herein in the singular form, they shall be construed as though they were also used in the plural form in all cases where they would so apply.

7.9 The Plan shall not be funded. No Eligible Employee shall have any right to, or interest in, any assets of any Company which may be applied by the Company to the payment of benefits or other rights under the Plan.

7.10 The laws of the Commonwealth of Virginia shall govern the interpretation, validity, administration, enforcement, and performance of the terms of the Plan regardless of the law that might be applied under principles of conflicts of laws. The parties agree that any suit, action, or proceeding arising out of or relating to the Plan shall be brought to the exclusive jurisdiction of the Circuit Court of Arlington County (Virginia) or the United States District Court for the Eastern District of Virginia (Alexandria Division). The parties irrevocably waive, to the fullest extent permitted by law, any objection a party may have to the laying of venue for any such suit, action or proceeding brought in such court. THE PARTIES ALSO EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT, ACTION OR PROCEEDING. If any one or more provisions of the Plan shall for any

reason be held invalid or unenforceable, it is the specific intent of the parties that such provisions shall be modified to the minimum extent necessary to make it or its application valid and enforceable.

7.11 Each Eligible Employee agrees to shorten the applicable statute of limitations and agrees that no claims or causes of actions may be brought against the Company or any its subsidiaries or affiliates or any of their directors, officers, employees, controlling persons, agents or representatives based upon, directly or indirectly, any claim that arises under the Plan more than twelve (12) months after the date of the action that is the subject of the claim or lawsuit. Each Eligible Employee agrees to waive any statute of limitations to the contrary.
