units (“RSUs”) granted to employees (the “RSU Award Agreement”), RSUs granted to non-employee directors (the

“Non-Employee Director RSU Award Agreement”) and RSUs that vest subject to performance-based criteria

(“PSUs”) (the “PSU Award Agreement” and collectively with the RSU Award Agreement and Non-Employee

Director RSU Award Agreement, the “Award Agreements”) and an employment agreement (each, an “Employment

Agreement”) with each of Steven J. Demetriou, John E. Heller, Stephen Arnette and Travis B. Johnson (the

“Executives”). The Severance Plan, each Award Agreement and each Employment Agreement was approved by the

Compensation Committee of the Company’s Board of Directors (the “Committee”). A summary description of each

is set forth below. Capitalized terms used and not otherwise defined herein shall have the meanings specified in the

relevant plan or agreement.

Amentum Holdings, Inc. Severance Plan for Key Employees

The Severance Plan is effective as of November 6, 2024. The Severance Plan is intended to be a top-hat welfare

benefit plan under ERISA. The primary purpose of the Severance Plan is to provide assurances of specified benefits

to certain executives of the Company, including the Company’s named executive officers, in the event of certain

terminations of employment as described in the Severance Plan.

The Committee serves as the administrator of the Severance Plan and selects those executive officers and other

employees of the Company and its affiliates who will be eligible to participate in the Severance Plan (referred to as

“Eligible Executives”).

Eligible Executives are entitled to certain benefits under the Severance Plan if the Eligible Executive experiences an

“Involuntary Termination” or an Involuntary Termination during the “Change in Control Period” as such terms are

defined under the Severance Plan. An Involuntary Termination occurs either when the Eligible Executive terminates

his or her employment with the Company and its affiliates for “Good Reason” or the Eligible Executive is

terminated for a reason other than “Cause,” the Eligible Executive’s death or Disability, in each case, as such terms

are defined under the Severance Plan. An Involuntary Termination during the “Change in Control Period” is

generally defined to be an Involuntary Termination occurring between three months prior to and 24 months

following a “Change in Control” as such terms are defined in the Severance Plan. No Eligible Executive is entitled

to severance benefits under the Severance Plan unless the executive enters into a release agreement with the

Company within the time period following his or her termination specified in the Severance Plan.

If an Eligible Executive experiences an Involuntary Termination and executes a release, the Eligible Executive is

entitled to the following benefits under the Severance Plan:

•Payments. The Eligible Executive will be paid the following amounts in a single lump sum on or

before the 70th day after the Eligible Executive’s Involuntary Termination:

oThe sum of the Eligible Executive’s “Annual Base Salary” and “Average Annual Bonus,” as

such terms are defined in the Severance Plan multiplied by the “Severance Multiplier” (which

is 1.5 for the chief financial officer and the chief operating officer and 1 for all other

participants (provided that the severance multiplier is not applicable to the executive chair or

the chief executive officer));

oAn amount in cash equal to the Eligible Executive’s “Target Annual Bonus” multiplied by the

“Proration Factor,” as such terms are defined in the Severance Plan; and

oDuring the “Severance Period (as described below),” if the Eligible Executive elects under

COBRA, to continue medical and dental coverage at the same benefit levels as provided to

active executive officers, a lump sum cash payment in an amount sufficient to cover the total

amount of the monthly medical and dental insurance premiums payable by the Eligible

Executive for continued benefits coverage pursuant to COBRA immediately prior to such

Eligible Executive’s Involuntary Termination; (b) a monthly cash payment grossed up for

taxes to permit the Eligible Executive to purchase life insurance coverage at the same benefit

level as currently provided to active executive officers and at the same cost to the Eligible

Executive as is generally provided to active executive officers; and (c) a lump cash payment

to permit the Eligible Executive to receive continued financial planning services at the same

benefit level as currently provided to active executive officers. The Severance Plan provides

that the Severance Period is 18 months for the chief financial officer and the chief operating

officer and 12 months for all other participants (provided that the severance period is not

applicable to the executive chair or the chief executive officer).

•Outplacement Services. The Company will reimburse an Eligible Executive for reasonable

outplacement services to be provided by a service provider selected by the Company during the

Severance Period.

If an Eligible Executive experiences an Involuntary Termination during the Change in Control Period and executes a

release, the Eligible Executive is entitled to the following benefits under the Severance Plan:

•Payments. The Eligible Executive will be paid the following amounts in a single lump sum on or

before the 70th day after the Eligible Executive’s Involuntary Termination:

oThe sum of the Eligible Executive’s “Annual Base Salary” and “Average Annual Bonus,” as

such terms are defined in the Severance Plan multiplied by the “CIC Severance

Multiplier,” (which is 2 for the executive chair and the chief executive officer, 1.5 for the

chief financial officer and the chief operating officer and 1 for all other participants);

oAn amount in cash equal to the Eligible Executive’s “Target Annual Bonus” multiplied by the

“Proration Factor,” as such terms are defined in the Severance Plan;

oDuring the “CIC Severance Period (as described below),” if the Eligible Executive elects

under COBRA, to continue medical and dental coverage at the same benefit levels as

provided to active executive officers, a lump sum cash payment in an amount sufficient to

cover the total amount of the monthly medical and dental insurance premiums payable by the

Eligible Executive for continued benefits coverage pursuant to COBRA immediately prior to

such Eligible Executive’s Involuntary Termination; (b) a monthly cash payment grossed up

for taxes to permit the Eligible Executive to purchase life insurance coverage at the same

benefit level as currently provided to active executive officers and at the same cost to the

Eligible Executive as is generally provided to active executive officers; and (c) a lump cash

payment to permit the Eligible Executive to receive continued financial planning services at

the same benefit level as currently provided to active Executive Officers. The Severance Plan

provides that the CIC Severance Period is 24 months for the executive chair and the chief

executive officer, 18 months for the chief financial officer and the chief operating officer and

12 months for all other participants; and

oThe Eligible Executive’s equity awards that remain unvested as of the date of the Eligible

Executive’s Involuntary Termination will accelerate in full and, to the extent applicable,

become immediately exercisable, with any outstanding performance-based vesting conditions

deemed achieved at the level of on target performance.

•Outplacement Services. The Company will reimburse an Eligible Executive for reasonable

outplacement services to be provided by a service provider selected by the Company during the CIC

Severance Period.

The Severance Plan does not provide for a gross-up payment to the Eligible Executive in the event that the Eligible

Executive is subject to an excise tax under Section 4999(a) of the Internal Revenue Code of 1986, as amended (the

“Code”). The payments or benefits will be reduced by the amount required to avoid the excise tax, if such reduction

would give the Eligible Executive a better after-tax result than if the Eligible Executive received the full payments

and benefits and paid the excise tax. The Severance Plan contains provisions for adjustment to the timing of

payments to minimize accelerated or additional tax pursuant to Section 409A of the Code. Claims for benefits under

the Severance Plan are governed by the Severance Plan’s claims procedure. If an Eligible Executive is a party to an

agreement with the Company or its affiliates that provides benefits upon an Involuntary Termination or a Change in

Control (or a similar phrase), the Eligible Executive will be entitled to receive either the aggregate payments and

benefits pursuant to the Severance Plan or such agreement(s), whichever is greater, but not both.

The foregoing description of the Severance Plan is hereby qualified in its entirety by reference to the full text of the

Severance Plan, which is filed herewith as Exhibit 10.1 and incorporated by reference herein.

Forms of RSU Award Agreement, Non-Employee Director RSU Award Agreement and PSU Award Agreement

On November 6, 2024, the Committee adopted the Award Agreements to be granted under Amentum Holdings, Inc.

2024 Stock Incentive Plan (the “Equity Plan”). Each of the Award Agreements (a) provides for the grant of RSUs or

PSUs, respectively, to an Eligible Individual under and as defined in the Equity Plan, which may, among other

things, be subject to (i) vesting in accordance with the vesting schedule provided in the applicable grant notice

(RSUs will vest based on continued service while the PSUs will vest based on the achievement of performance

criteria during the performance period) and (ii) certain transfer restrictions, and (b) authorizes the Company to cause

shares to be sold on the Eligible Individual’s account to cover applicable withholding taxes due upon vesting of the

shares underlying the RSUs or PSUs, as applicable. The Non-Employee Director RSU Award Agreement also

provides that all of the RSUs will vest in full immediately prior to a change in control (as defined in the Equity

Plan), subject to the holder’s continued service through such date.

The foregoing description of the Award Agreements is hereby qualified in its entirety by reference to the full text of

the Award Agreements, which are filed herewith as Exhibits 10.2, 10.3 and 10.4 and incorporated by reference

herein.

any unvested long-term incentive award held by him shall immediately vest to the extent they would have

vested if he had incurred a termination of employment under the terms of Jacobs’ Executive Severance Plan

(taking into account any applicable pro ration and other terms and conditions), as in effect on the Closing

Date, and, to the extent so vested, settle as of such date of termination.

Severance upon Death or Disability

terms of Jacobs’ Executive Severance Plan (taking into account any applicable pro ration and other terms and

conditions), as in effect on the Closing Date, and, to the extent so vested, settle as of such date of termination.

Other Terms and Provisions

The Employment Agreements include non-competition, non-solicitation of employees and customer restrictions,

non-disclosure of confidential information and other customary restrictive covenants.

The Employment Agreements provide that if any payments or benefits provided to the Executive would constitute

excess parachute payments within the meaning of Section 280G of the Code, and would be subject to the excise tax

imposed under Section 4999 of the Code, the payments or benefits will be reduced by the amount required to avoid

the excise tax, if such reduction would give the Executive a better after-tax result than if he received the full

payments and benefits and paid the excise tax.

Term of the Employment Agreements

During the Initial Term, Mr. Demetriou’s employment may not be terminated other than by the Company for Cause

or as a result of his death or disability. Such employment with the Company is “at will” following the initial term if

Mr. Demetriou continues in his role as Executive Chair of the Company.

The initial term of the employment of each of Mr. Heller, Mr. Johnson and Mr. Arnette is two years from the

Closing Date, which term will automatically renew for subsequent one-year terms unless either party provides notice

of non-renewal at least 60 days prior to the end of the then-current term. Such employment with the Company is “at

will” and, subject to certain provisions of the Employment Agreements, such employment under the Employment

Agreements may be terminated by the Company or the applicable Executive at any time and for any reason, with or

without prior notice.

The foregoing description of each of the Employment Agreements is hereby qualified in its entirety by reference to

the full text of each of the Employment Agreements, which are filed herewith as Exhibits 10.5, 10.6, 10.7 and 10.8

and incorporated by reference herein.

5.5.Equity Award Vesting Acceleration Benefit. The Participant’s Equity Awards that remain unvested as of the date of the Participant’s Involuntary Termination will accelerate in full and, to the extent applicable, become immediately exercisable, with any outstanding performance-based vesting conditions deemed achieved at the level of on target performance. Subject to Section 9, any vested restricted stock units will be settled on or before the 70th day after the Participant’s Involuntary Termination.

5.6.Coordination with Severance Benefits Payable Pursuant to Section 4. Notwithstanding the foregoing, in the event the Participant experiences an Involuntary Termination prior to a Change in Control and becomes entitled to receive Severance Benefits pursuant to Section 4, (a) the cash Severance Benefits the Participant will be eligible to receive pursuant to Sections 5.1, 5.2 and 5.3 will be reduced (but not below zero) by the cash Severance Benefits the Participant received or is entitled to receive pursuant to Sections 4.1., 4.2 and 4.3 or, if the Participant is not eligible to receive Severance Benefits pursuant to Section 4, the cash severance payments and (b) any Equity Awards that were unvested as of the date of the Participant’s Involuntary Termination and would have been forfeited pursuant to their terms will instead accelerate in full as of the Change in Control, with any performance-based awards deemed earned based on target performance (or such greater amount as may be provided for in connection with such Change in Control). Any excess cash Severance Benefits that become payable to the Participant and any additional restricted stock units that accelerate vesting, in each case pursuant to this Section 5.6, will, subject to Section 9, be paid or settled, as applicable, as soon as practicable following the Change in Control and in no event later than 30 days following the Change in Control.

6.Limitation on Payments. In the event that the Severance Benefits and any other severance or benefits otherwise payable to a Participant (a) constitute “parachute payments” within the meaning of Section 280G (the “280G Payments”) and (b) but for this Section 6, would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Participant will be entitled to receive either (i) the full amount of the 280G Payments or (ii) the maximum amount that may be provided to the Participant without resulting in any portion of such 280G Payments being subject to such Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local taxes and the Excise Tax, results in the receipt by the Participant, on an after-tax basis, of the greatest portion of the 280G Payments. If a reduction in the 280G Payments is necessary so that no portion of such benefits is subject to the Excise Tax, such reduction will occur in the following order: (A) any cash payment under any retention bonus agreement or similar agreement, (B) any cash severance payable pursuant to this Plan; (C) any other cash amount payable to the Participant; (D) any benefit valued as a 280G Payment; and (E) acceleration of vesting of any equity award. Such reduction shall be first applied to payments and benefits in each of the forgoing categories in reverse order beginning with the payments or benefits that are to be paid the furthest in time from the date of such determination. Any determination required under this Section 6 will be made in writing by a nationally recognized public accounting firm designated by public accountants of the Company or, if so designated by the Company prior to the event triggering Section 280G, the Company or such other person or entity as determined in good faith by the Company, in each case, whose determination will be conclusive and binding upon the Participant. For purposes of making the calculations required by this Section 6, the individual or entity making the determinations provided for under this Section 6 may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code.

7.Conditions to Receipt of Severance.

7.1.Release Agreement. As a condition to receiving the Severance Benefits, each Participant will be required to sign and not revoke a separation and release of claims agreement in a form reasonably satisfactory to the Company (the “Release”). In all cases, the Release must become effective and irrevocable no later than the 60th day following the Participant’s Involuntary Termination (the “Release Deadline Date”). If the Release does not become effective and irrevocable by the Release Deadline Date, the Participant will forfeit any right to the Severance Benefits. In no event will the Severance Benefits be paid or provided until the Release becomes effective and irrevocable.

7.2.Confidential Information and Other Requirements. A Participant’s receipt of Severance Benefits will be subject to the Participant continuing to comply with the terms of any employee invention and confidentiality agreement or similar agreement, including any Individual Agreement that includes restrictive covenant obligations, between the Participant and the Company. Any unpaid Severance Benefits under this Plan will be forfeited immediately if the Participant violates any such agreement and/or the provisions of this Section 7.

8.Other Arrangements. Notwithstanding any provision of this Plan, but subject to the limitation on 280G Payments set forth in Section 6, in the case of an Involuntary Termination of a Participant who is party to one or more Individual Agreements, such Participant will be entitled under this Plan to receive either the aggregate severance payments and benefits provided under (a) this Plan or (b) such Individual Agreements, whichever is greater (but not both); provided, however, that the severance payments and other benefits provided herein or under such Individual Agreement will be made at the time and in the form necessary to comply with, and not trigger any taxes or penalties under, Section 409A. For the avoidance of doubt, any Severance Benefits payable hereunder will not result in a duplication of the amount the Participant is eligible to receive pursuant to any Individual Agreement. If a Participant was otherwise eligible to participate in any other Company severance and/or change in control plan (whether or not subject to ERISA), then participation in this Plan will supersede and replace eligibility in such other plan.

9.Section 409A.

9.1.This Plan and the Severance Benefits are intended to comply with or be exempt from the requirements of Section 409A and will be construed and interpreted in accordance with such intent. To the extent that any Severance Benefit is subject to Section 409A, the Severance Benefit will be granted, paid, settled or deferred in a manner that will meet the requirements of Section 409A in order to avoid taxes or penalties under Section 409A.

9.2.No Participant or the creditors or beneficiaries of a Participant will have the right to subject any deferred compensation (within the meaning of Section 409A) payable under this Plan to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment. Except as permitted under Section 409A, any deferred compensation (within the meaning of Section 409A) payable to any Participant or for the benefit of any Participant under this Plan may not be reduced by, or offset against, any amount owing by any such Participant to the Company or any of its Affiliates.

9.3.If, at the time of a Participant’s separation from service (within the meaning of Section 409A), (a) such Participant is a specified employee (within the meaning of Section 409A and using the identification methodology selected by the Company from time to time) and (b) the Company makes a good-faith determination that an amount payable pursuant to this Plan constitutes deferred compensation (within the meaning of Section 409A), the payment of which is required to be delayed pursuant to the six-month delay rule set forth in Section 409A in order to avoid taxes or penalties under Section 409A, then the Company will not pay such amount on the otherwise scheduled payment date but will instead pay it on the first business day after such six-month period. Such amount will be paid without interest, unless otherwise determined by the Administrator, in its discretion, or as otherwise provided in any Individual Agreement.

9.4.Notwithstanding any provision of this Plan to the contrary, in light of the uncertainty with respect to the proper application of Section 409A, the Company reserves the right to

make amendments to this Plan as the Company deems necessary or desirable, in its sole discretion and without the consent of the Participants, to avoid the imposition of taxes or penalties under Section 409A. In any case, a Participant will be solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on such Participant or for such Participant’s account in connection with any Severance Benefits (including any taxes and penalties under Section 409A), and neither the Company nor any of its Affiliates will have any obligation to indemnify or otherwise hold such Participant harmless from any or all of such taxes or penalties.

9.5.Each payment and benefit payable under this Plan is intended to constitute a separate payment for purposes of Section 409A. In addition, to the extent necessary to comply with Section 409A, if the period during which a Release must be executed and become irrevocable spans two calendar years, payment of the Severance Benefits will commence in the second calendar year.

10.Withholdings. The Company or any Affiliate will have the right and is hereby authorized to withhold from any Severance Benefits due under this Plan or from any compensation or other amount owing to a Participant, the amount (in cash, shares, other securities or other property) of any applicable withholding taxes in respect of the amounts payable under this Plan and to take such other action as may be necessary in the opinion of the Administrator or the Company to satisfy all obligations for the payment of such taxes.

11.Administration. This Plan will be administered and interpreted by the Administrator (in his, her or its sole discretion). The Administrator is the “named fiduciary” of this Plan for purposes of ERISA and will be subject to the fiduciary standards of ERISA when acting in such capacity. Any decision made or other action taken by the Administrator with respect to this Plan, and any interpretation by the Administrator of any term or condition of this Plan, or any related document, will be conclusive and binding on all persons and be given the maximum possible deference allowed by law. In accordance with Section 2.1, the Administrator (a) may, in its sole discretion and on such terms and conditions as it may provide, delegate in writing to one or more officers of the Company all or any portion of its authority or responsibility with respect to this Plan and (b) has the authority to act for the Company (in a non-fiduciary capacity) as to any matter pertaining to this Plan; provided, however, that any Plan amendment or termination or any other action that reasonably could be expected to increase materially the cost of this Plan must be approved by the Board.

12.Eligibility to Participate. To the extent that the Administrator has delegated administrative authority or responsibility to one or more officers of the Company in accordance with Sections 2.1 and 11, each such officer will not be excluded from participating in this Plan if otherwise eligible, but he or she is not entitled to act upon or make determinations regarding any matters pertaining specifically to his or her own benefit or eligibility under this Plan. The Administrator will act upon and make determinations regarding any matters pertaining specifically to the benefit or eligibility of each such officer under this Plan.

13.Amendment or Termination. The Board, by action of the Administrator, reserves the right to amend or terminate this Plan or the benefits provided hereunder at any time, subject to the provisions of this Section 13. Any amendment or termination will be effective as of the date determined by the Board; provided, however, that, except as set forth in Section 9, any such amendment or termination will not affect any right of any Participant to claim benefits under this Plan for events occurring prior to the effective date of such amendment or termination. Any amendment or termination of this Plan will be in writing. Notwithstanding the foregoing, beginning on the date that a Change in Control occurs, the Company may not, without a Participant’s written consent, amend or terminate this

Plan in any way, nor take any other action under this Plan, which (a) prevents the Participant from becoming eligible for Severance Benefits or (b) reduces or alters to the detriment of the Participant the Severance Benefits payable, or potentially payable, to the Participant (including, without limitation, imposing additional conditions). Any action of the Company in amending or terminating this Plan will be taken in a non-fiduciary capacity.

14.Claims and Appeals.

14.1.Claims Procedure. Any employee or other person who believes he or she is entitled to any Severance Benefits may submit a claim in writing to the Administrator within 90 days of the earlier of (a) the date the claimant learned the amount of his or her Severance Benefits and (b) the date the claimant learned that he or she will not be entitled to any Severance Benefits. If the claim is denied (in full or in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of this Plan on which the denial is based. The notice also will describe any additional information needed to support the claim and this Plan’s procedures for appealing the denial. The denial notice will be provided within 90 days after the claim is received. If special circumstances require an extension of time (up to 90 days), written notice of the extension will be given within the initial 90-day period. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which the Administrator expects to render its decision on the claim.

14.2.Appeal Procedure. If the claimant’s claim is denied, the claimant (or his or her authorized representative) may apply in writing to the Administrator for a review of the decision denying the claim. Review must be requested within 60 days following the date the claimant received the written notice of their claim denial or else the claimant loses the right to review. The claimant (or representative) then has the right to review and obtain copies of all documents and other information relevant to the claim, upon request and at no charge, and to submit issues and comments in writing. The Administrator will provide written notice of its decision on review within 60 days after it receives a review request. If additional time (up to 60 days) is needed to review the request, the claimant (or representative) will be given written notice of the reason for the delay. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which the Administrator expects to render its decision. If the claim is denied (in full or in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of this Plan on which the denial is based. The notice also will include a statement that the claimant will be provided, upon request and free of charge, reasonable access to, and copies of, all documents and other information relevant to the claim and a statement regarding the claimant’s right to bring an action under Section 502(a) of ERISA. The decision of the Administrator is final and binding on all parties.

15.Attorneys’ Fees. The parties will each bear their own expenses, legal fees and other fees incurred in connection with this Plan.

16.Source of Payments. All payments under this Plan will be paid from the general funds of the Company; no separate fund will be established under this Plan, and this Plan will have no assets. No right of any person to receive any payment under this Plan will be any greater than the right of any other general unsecured creditor of the Company.

17.Benefits Nontransferable. In no event may any current or former employee of the Company or any of its Affiliates sell, transfer, anticipate, assign or otherwise dispose of any right or interest under this Plan. At no time will any such right or interest be subject to the claims of creditors nor liable to attachment, execution or other legal process.

18.No Right to Continued Employment. Neither the establishment or maintenance or amendment of this Plan, nor the making of any benefit payment hereunder, will be construed to confer upon any individual any right to continue to be an employee of the Company. This Plan in no way alters a Participant’s at-will employment arrangement with the Company, and the Company expressly reserves the right to discharge any of its employees, including the Participant, at any time, with or without cause. However, as described in this Plan, a Participant may be entitled to Severance Benefits depending upon the circumstances of his or her termination of employment.

19.Successors. Any successor to the Company of all or substantially all of the Company’s business and/or assets (whether direct or indirect and whether by purchase, merger, consolidation, liquidation or other transaction) will assume the obligations under this Plan and agrees expressly to perform the obligations under this Plan in the same manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession. For all purposes under this Plan, the term “Company” will include any successor to the Company’s business and/or assets which become bound by the terms of this Plan by operation of law, or otherwise.

20.Applicable Law. This Plan will be governed by, and construed in accordance with, ERISA, and, to the extent applicable, the laws of the Commonwealth of Virginia, as such laws are applied to contracts entered into and performed in such Commonwealth. For purposes of any action, lawsuit or other proceedings brought to enforce this Plan, relating to it, or arising from it, the parties hereby submit to and consent to the sole and exclusive jurisdiction of the United States District Court for the Eastern District of Virginia, or, if such court does not have subject matter jurisdiction, the state courts of Virginia located in Fairfax County, and no other courts, where this Plan is made and/or to be performed.

21.Severability. If any provision of this Plan is or becomes or is deemed to be invalid, illegal or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity, illegality or unenforceability will not affect the remaining parts of this Plan, and this Plan will be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included.

22.Headings and Construction. Headings are given to the Sections and subsections of this Plan solely as a convenience to facilitate reference. Such headings will not be deemed in any way material or relevant to the construction or interpretation of this Plan or any provision thereof. Whenever the words “include”, “includes” or “including” are used in this Plan, they will be deemed to be followed by the words “but not limited to”, and the word “or” will not be deemed to be exclusive. Pronouns and other words of gender will be read as gender neutral. Words importing the plural will include the singular and the singular will include the plural.

23.Indemnification. The Company hereby agrees to indemnify and hold harmless the officers and employees of the Company, and the members of its Board, from all losses, claims, costs or other liabilities arising from their acts or omissions in connection with the administration, amendment or termination of this Plan, to the maximum extent permitted by applicable law. This indemnity will cover all such liabilities, including judgments, settlements and costs of defense. The Company will provide this indemnity from its own funds to the extent that insurance does not cover such liabilities. This indemnity is in addition to and not in lieu of any other indemnity provided to such person by the Company.

The terms of your RSU Award as specified in this Award Agreement for your RSU Award (the “Agreement”) and the Grant Notice constitute your “RSU Award Agreement”.

2.Grant of the RSU Award. This RSU Award represents your right to be issued on a future date the number of shares of Common Stock that is equal to the number of Restricted Stock Units indicated in the Grant Notice, subject to your satisfaction of the vesting conditions set forth therein. Any additional Restricted Stock Units that become subject to the RSU Award pursuant to a Change in Capitalization as set forth in the Plan and the provisions of Section 3 below, if any, shall be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as applicable to the other Restricted Stock Units covered by your RSU Award.

3.Dividends. As described in Section 8(d) of the Plan, you shall be entitled to a Dividend Equivalent Right with respect to each Restricted Stock Unit subject to the RSU Award.

4.Withholding Obligations.

(a)Regardless of any action taken by the Company or, if different, the Related Company to which you provide service (the “Service Recipient”) with respect to any income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items associated with the grant, vesting, or settlement of the RSU Award or sale of the underlying Common Stock or other tax-related items related to your participation in the Plan and legally applicable to you (the “Tax Liability”), you hereby acknowledge and agree that the Tax Liability is your ultimate responsibility and may exceed the amount, if any, actually withheld by the Company or the Service Recipient. You further acknowledge that the Company and the Service Recipient (i) make no representations or undertakings regarding any Tax Liability in connection with any aspect of this RSU Award, including, but not limited to, the grant or vesting of the RSU Award, the issuance of Common Stock pursuant to such vesting, the subsequent sale of shares of Common Stock, and the payment of any dividends on the Common Stock; and (ii) do not commit to, and are under no obligation to, structure the terms of the grant or any aspect of the RSU Award to reduce or eliminate your Tax Liability or achieve a particular tax result. Further, if you are subject to Tax Liability in more than one jurisdiction, you acknowledge that the Company and/or the Service Recipient (or former service recipient, as applicable) may be required to withhold or account for Tax Liability in more than one jurisdiction.

(b)Prior to any relevant taxable or tax withholding event, as applicable, you agree to make adequate arrangements satisfactory to the Company and/or the Service Recipient to satisfy all Tax Liability. As further provided in Section 19 of the Plan, you hereby authorize the Company and any applicable Service Recipient to satisfy any applicable withholding obligations with regard to the Tax Liability by any of the following means or by a combination of such means: (i) causing you to pay any portion of the Tax Liability in cash or cash equivalent in a form acceptable to the Company; (ii) withholding from any compensation otherwise payable to you by the Company or the Service Recipient; (iii) withholding shares of Common Stock from the shares of Common Stock

issued or otherwise issuable to you in connection with the Award; provided, however, that to the extent necessary to qualify for an exemption from application of Section 16(b) of the Exchange Act, if applicable, such share withholding procedure will be subject to the express prior approval of the Board or the Company’s Compensation Committee; (iv) permitting or requiring you to enter into a “same day sale” commitment, if applicable, with a broker-dealer that is a member of the Financial Industry Regulatory Authority (a “FINRA Dealer”), pursuant to this authorization and without further consent, whereby you irrevocably elect to sell a portion of the shares of Common Stock to be delivered in connection with your Restricted Stock Units to satisfy the Tax Liability and whereby the FINRA Dealer irrevocably commits to forward the proceeds necessary to satisfy the Tax Liability directly to the Company or the Service Recipient; and/or (v) any other method determined by the Company to be in compliance with applicable law. Furthermore, you agree to pay the Company or the Service Recipient any amount the Company or the Service Recipient may be required to withhold, collect, or pay as a result of your participation in the Plan or that cannot be satisfied by the means previously described. In the event it is determined that the amount of the Tax Liability was greater than the amount withheld by the Company and/or the Service Recipient (as applicable), you agree to indemnify and hold the Company and/or the Service Recipient (as applicable) harmless from any failure by the Company or the applicable Service Recipient to withhold the proper amount.

(c)The Company may withhold or account for your Tax Liability by considering statutory withholding amounts or other withholding rates applicable in your jurisdiction(s), including (i) maximum applicable rates in your jurisdiction(s), in which case you may receive a refund of any over-withheld amount in cash (whether from applicable tax authorities or the Company) and you will have no entitlement to the equivalent amount in Common Stock or (ii) minimum or such other applicable rates in your jurisdiction(s), in which case you may be solely responsible for paying any additional Tax Liability to the applicable tax authorities or to the Company and/or the Service Recipient. If the Tax Liability withholding obligation is satisfied by withholding shares of Common Stock, for tax purposes, you are deemed to have been issued the full number of shares of Common Stock subject to the vested portion of the RSU Award, notwithstanding that a number of the shares of Common Stock is held back solely for the purpose of paying such Tax Liability.

(d)You acknowledge that you may not participate in the Plan and the Company shall have no obligation to deliver shares of Common Stock until you have fully satisfied the Tax Liability, as determined by the Company. Unless any withholding obligation for the Tax Liability is satisfied, the Company shall have no obligation to deliver to you any Common Stock in respect of the RSU Award.

5.Date of Issuance.

(a)The issuance of shares in respect of the Restricted Stock Units is intended to comply with, or be exempt from the application of, Section 409A of the Code and the RSU Award Agreement will be construed and administered consistent with that intent. Subject to the satisfaction of the Tax Liability withholding obligation, if any, in the event one or more Restricted Stock Units vests, the Company shall issue to you, on such date (or as soon as administratively practicable thereafter), one (1) share of Common Stock for each vested, but unsettled, Restricted Stock Unit. Each issuance date determined by this paragraph is referred to as an “Original Issuance Date.”

(b)Notwithstanding the foregoing, if the potential Original Issuance Date does not occur (i) during an “open window period” applicable to you, as determined by the Company in accordance with the Company’s then-effective policy on trading in Company securities, or (ii) on a date when you are otherwise permitted to sell shares of Common Stock on an established stock exchange or stock market (including but not limited to under a previously established written trading plan that meets the requirements of Rule 10b5-1 under the Exchange Act and was entered into in compliance with the Company’s policies), then the shares that would otherwise be issued to you will be delivered on such date as the Company may determine.

(c)Notwithstanding clauses (a) and (b) to the contrary, in all cases, the shares of Common Stock to be issued in settlement of vested Restricted Stock Units shall be issued no later than the date that is the 15th day of the third calendar month of the applicable year following the year in which the applicable Restricted Stock

Units were no longer subject to a “substantial risk of forfeiture” within the meaning of U.S. Treasury Regulations Section 1.409A-1(d).

6.Transferability. Except as otherwise provided in the Plan, your RSU Award is not transferable, except by will or by the applicable laws of descent and distribution.

7.Change in Control. Your RSU Award is subject to the terms of any agreement governing a Change in Control involving the Company, including, without limitation, a provision for the appointment of a stockholder representative that is authorized to act on your behalf with respect to any escrow, indemnities and any contingent consideration.

8.No Liability for Taxes. As a condition to accepting the RSU Award, you hereby (a) agree to not make any claim against the Company, or any of its officers, directors, employees or Affiliates related to tax liabilities arising from the RSU Award or other Company compensation and (b) acknowledge that you were advised to consult with your own personal tax, financial and other legal advisors regarding the tax consequences of the RSU Award and have either done so or knowingly and voluntarily declined to do so.

9.Severability. If any part of this Agreement or the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Agreement (or part of such a Section) so declared to be unlawful or invalid will, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid.

10.Other Documents. You hereby acknowledge receipt of or the right to receive a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act, which includes the Prospectus. In addition, you acknowledge receipt of the Company’s trading policy.

11.Questions. If you have questions regarding these or any other terms and conditions applicable to your RSU Award, including a summary of the applicable federal income tax consequences please see the Prospectus.

NOW, THEREFORE, in consideration of the premises and mutual agreements herein contained, the parties hereto do hereby agree as follows:

ARTICLE I

Employment

SECTION 1.01. Term. Subject to the terms of this Agreement, the term of Executive’s employment under this Agreement commenced on the Closing Date (as defined in the Merger Agreement) and shall terminate on the second anniversary of the Closing Date (such two-year period, unless earlier terminated in accordance with this Agreement, the “Initial Term”).

(iv) a material breach by the Combined Company (or a successor) of this Agreement or any other agreement between the Combined Company and Executive;

provided, however, that such event will not constitute Good Reason under this Agreement unless (x) Executive provides notice to the Combined Company within 30 days following the initial existence of an event constituting Good Reason, (y) the Combined Company does not remedy such event (if remediation is possible) within 30 days following the Combined Company’s receipt of notice of such event, and (z)

Executive separates from service with the Combined Company within 90 days following the initial existence of such an event constituting Good Reason.

SECTION 4.03. Termination by Executive for Good Reason. If Executive terminates Executive’s employment with the Combined Company for Good Reason prior to the second anniversary of the Closing Date, Executive shall be entitled to the Accrued Rights and; provided that Executive has provided a general release in favor of the Combined Company and its subsidiaries and affiliates, and their respective directors, officers, employees, agents and representatives in form and substance reasonably acceptable to the Combined Company (the “Release”) and the Release has become effective and irrevocable prior to the 60th day after such termination of employment, Executive shall be entitled to the following:

(a) Cash Payments. (i) The Combined Company shall pay to Executive an amount equal to 1.5 times the sum of Executive’s Base Salary and target Annual Bonus amount, payable in equal installments through the date that is 18 months after the date of Executive’s termination of employment (the “Severance Period”) at the same times at which and in the same manner in which Executive’s Base Salary would have been payable to Executive had a termination of employment not occurred, and (ii) the Combined Company shall provide to Executive, during the calendar year following the calendar year in which Executive’s termination of employment occurs, an Annual Bonus for the fiscal year in which the termination occurs equal to the Annual Bonus that Executive would have received if his employment had not terminated prior to the end of the fiscal year (e.g., after determining whether applicable performance goals have been achieved, determined on a basis consistent with past practice), pro-rated based on a fraction, the numerator of which shall equal the number of days Executive was employed by the Combined Company in the fiscal year in which Executive’s termination occurs and the denominator of which shall equal 365 (the “Pro-Rata Bonus”); provided, however, that, in the case of clause (i), the Combined Company shall (x) commence such payments on the 60th day after termination of Executive’s employment, except that any payments that would have otherwise been paid to Executive following the date of the termination of employment and prior to such 60th day shall be accumulated and paid to Executive in a lump sum on the first payment date following such 60th day, and (y) not continue such payments at any time following either (A) breach of the provisions of Section 5.03 or 5.04 or (B) breach of the provisions of Article V (other than Section 5.03 or 5.04) that (X) is materially damaging to the business or reputation of the Combined Company or any of its affiliates or (Y) occurs after the Combined Company has notified Executive more than once of a prior breach of such Article V (other than Section 5.03 or 5.04).

Reconciliation Act of 1985, as amended, that would be payable by Executive for continued participation in the Combined Company’s group health plans (including medical and dental insurance) in which Executive participates as of immediately prior to the date of Executive’s termination of employment. Such lump sum cash payments pursuant to this Section 4.03(b) shall be paid within 90 days following the date of Executive’s termination of employment, subject to Section 4.03(e) below. In addition, the Combined Company shall pay Executive a monthly cash payment grossed up for taxes to permit Executive to purchase life insurance coverage at the same benefit level as currently provided to active senior executives of the Combined Company and at the same cost to Executive as is generally provided to active senior executives of the Combined Company.

(c) Outplacement. Executive shall receive reasonable outplacement services to be provided by a provider selected by Executive during the Severance Period, the cost of which shall be borne by the Combined Company; provided, however, that notwithstanding the foregoing, Executive shall commence using such services within 12 months of Executive’s termination of employment, such outplacement services shall end not later than the last day of the second calendar year that begins after the date of termination of Executive’s employment and the Combined Company shall pay any amounts in respect of such outplacement services not later than the last day of the third calendar year that begins after such date of termination.

(d) Long-Term Incentive Awards. Any unvested long-term incentive award granted to Executive pursuant to Section 2.03 of this Agreement shall immediately vest and settle as of such date of termination.

(e) Release. For the avoidance of doubt, (x) the Release shall not require Executive to release any rights to post-termination payments or benefits afforded to him by this Agreement, or any vested benefits or rights pursuant to the terms of the Combined Company’s and its affiliates’ benefit plans or programs, or to any rights related to his ownership of fully vested equity securities of the Combined Company, and (y) if the Release does not become effective and irrevocable within 60 days following the date of Executive’s termination of employment pursuant to this Section 4.03(e), the Combined Company shall not be obligated to make any payments or provide any benefits under Section 4.03(a), (b), (c) or (d) above and Executive shall only be entitled to the Accrued Rights.

shall immediately vest and settle as of the date of Executive’s termination due to death or Disability. For purposes of this Agreement, the term “Disability” shall mean (a) the inability of Executive, due to illness, accident or any other physical or mental incapacity, to perform Executive’s duties in a normal manner for a period of 180 days (whether or not consecutive) in any twelve-month period during the term of Executive’s employment under this Agreement or (b) Executive being accepted for long-term disability benefits under any long-term disability plan in which he is then participating. The Board shall determine, according to the facts then available, whether and when the Disability of Executive has occurred. Such determination shall not be arbitrary or unreasonable and the Board will take into consideration the expert medical opinion of a physician chosen by the Combined Company, after such physician has completed an examination of Executive. Executive agrees to make himself available for such examination upon the reasonable request of the Combined Company.

SECTION 4.05. Coordination of Benefits. In the event of a “change in control” of the Combined Company, Executive shall be eligible to receive the severance benefits provided for under any severance plan of the Company providing for severance benefits in connection with such change in control (the “Severance Plan”). Notwithstanding the foregoing, in no event shall Executive be entitled to receive severance benefits under both this Agreement and the Severance Plan and shall receive either the severance benefits provided for under this Agreement or those provided for under the Severance Plan, whichever is greater.

All rights to discoveries, inventions, improvements and innovations (including all data and records pertaining thereto) related to the business of the Combined Company or its current or former affiliates, whether or not patentable, copyrightable, registrable as a trademark, or reduced to writing, that Executive may discover, invent or originate during the term of Executive’s service to the Combined Company or its affiliates (whether before, on or after the Closing Date), either alone or with others and whether or not during working hours or by the use of the facilities of the Combined Company (“Inventions”), shall be the exclusive property of the Combined Company or its designee. Executive shall promptly disclose all Inventions to the Combined Company. Executive shall take all requested actions and execute all requested documents to assist the Combined Company, or its designee, at the Combined Company’s expense, in every way to secure the Combined Company’s or its designee’s above rights in the Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating thereto in any and all countries, and to pursue any patents or registrations with respect thereto. This covenant shall survive the termination of this Agreement. If the Combined Company or its designee is unable for any other reason to secure Executive’s signature on any document for this purpose, then Executive hereby irrevocably designates and appoints the Combined Company or its designee and their duly authorized officers and agents, as the case may be, as Executive’s agent and attorney-in-fact, to act for and in Executive’s behalf and stead to execute any documents and to do all other lawfully permitted acts in connection with the foregoing.

Upon termination of employment with the Combined Company for any reason, (a) Executive will immediately return to the Combined Company all such memoranda, books, records, documents, papers, plans, information, letters and other data, and all copies thereof or therefrom, and Executive will not retain, or cause or permit to be retained, any copies or other embodiments of the materials so returned and (b) Executive shall delete all documents, materials, and information (and copies thereof) of the Combined Company from all Executive’s personal electronic devices (e.g., laptop, iPad, telephone, thumb drives, etc.).

Combined Company for any reason (the “Non-Disparagement Period”), unless in the context of litigation between the Combined Company and Executive or under penalty of perjury or otherwise permitted pursuant to Section 5.07, whether in writing or orally, criticize or disparage the Combined Company or any of its respective current or former affiliates, directors, officers, employees, members, partners, agents or representatives. The Combined Company shall instruct the Company Parties (as defined below) not to, whether in writing or orally, criticize or disparage Executive during the Non-Disparagement Period, unless in the context of litigation between the Combined Company and Executive or under penalty of perjury. For purposes of this Agreement, the term the “Company Parties” shall mean the executive officers and designated spokespersons of the Combined Company, acting in their capacity as representatives of the Combined Company.

SECTION 5.11. Specific Performance. Executive agrees that any breach by Executive of any of the provisions of this Article V shall cause irreparable harm to the Combined Company that could not be made whole by monetary damages and that, in the event of such a breach, Executive shall waive the defense in any action for specific performance that a remedy at law would be adequate, and the Combined Company shall be entitled to specifically enforce the terms and provisions of this Article V without the necessity of proving actual damages or posting any bond or providing prior notice, in addition to any other remedy to which the Combined Company may be entitled at law or in equity.

SECTION 6.06. Governing Law and Jurisdiction. (a) This Agreement and any disputes arising under or related hereto (whether for breach of contract, tortious conduct or otherwise) shall be governed and construed in accordance with the laws of the Commonwealth of Virginia, without reference to its conflicts of law principles. Each party irrevocably agrees that any legal action, suit or proceeding against them arising out of or in connection with this Agreement or the transactions contemplated by this Agreement or disputes relating hereto (whether for breach of contract, tortious conduct or otherwise) shall be brought exclusively in the United States District Court for the Eastern District of Virginia, or, if such court does not have subject matter jurisdiction, the state courts of Virginia located in Fairfax County and hereby irrevocably accepts and submits to the exclusive jurisdiction and venue of the aforesaid courts in personam, with respect to any such action, suit or proceeding.

(b) Each party hereby waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement. Each party (i) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other parties hereto have been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 6.06(b).

(c) In the event of any dispute or legal action arising under this Agreement, each party shall be responsible for bearing its own expenses, attorneys’ fees and other costs during the pendency of such dispute or legal action, except that in the event of a legal action in which one party prevails on all or substantially all of the matters subject to the dispute, the prevailing party shall be entitled to reimbursement from the other party for all expenses, attorneys’ fees and other costs incurred in connection with such legal action.

SECTION 6.07. Severability. If any term, provision, covenant or condition of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable in any jurisdiction, then such provision, covenant or condition shall, as to such jurisdiction, be modified or restricted to the extent necessary to make such provision valid, binding and enforceable, or, if such provision cannot be modified or restricted, then such provision shall, as to such jurisdiction, be deemed to be excised from this Agreement and any such invalidity, illegality or unenforceability with respect to such provision shall not invalidate or render unenforceable such provision in any other jurisdiction, and the remainder of the provisions hereof shall remain in full force and effect and shall in no way be affected, impaired or invalidated.

SECTION 6.08. Survival. The rights and obligations of the Combined Company and Executive under the provisions of this Agreement, including Articles V and VI, shall survive and remain binding and enforceable, notwithstanding any termination of Executive’s employment with the Combined Company or a termination of

this Agreement, in each case to the extent necessary to preserve the intended benefits of such provisions.

SECTION 6.09. Cooperation. Executive shall provide Executive’s reasonable cooperation to the Combined Company in connection with any suit, action or proceeding (or any appeal therefrom) that relates to events occurring during Executive’s employment with the Combined Company or any of its affiliates other than a suit between Executive, on the one hand, and the Combined Company, on the other hand; provided that the Combined Company shall reimburse Executive at a reasonable rate for his time (if Executive is no longer employed by the Combined Company) and for expenses reasonably incurred in connection with such cooperation.

SECTION 6.10. No Waiver. The provisions of this Agreement may be waived only in writing signed by the party or parties entitled to the benefit thereof. A waiver or any breach or failure to enforce any provision of this Agreement shall not in any way affect, limit or waive a party’s rights hereunder at any time to enforce strict compliance thereafter with every provision of this Agreement.

SECTION 6.11. Set Off. The Combined Company’s obligation to pay Executive the amounts provided and to make the arrangements provided hereunder shall be subject to set off, counterclaim or recoupment of amounts owed by Executive to the Combined Company or its affiliates, except as provided in Section 6.13.

SECTION 6.12. Withholding Taxes. The Combined Company may withhold from any amounts payable under this Agreement such Federal, state, local and foreign taxes as may be required to be withheld pursuant to any applicable law or regulation.

SECTION 6.13. Section 409A. (a) It is intended that the provisions of this Agreement comply with Section 409A of the Code (“Section 409A”) or an exemption thereunder, and all provisions of this Agreement shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A.

(b) Neither Executive nor any of his creditors or beneficiaries shall have the right to subject any deferred compensation (within the meaning of Section 409A) payable under this Agreement or under any other plan, policy, arrangement or agreement of or with the Combined Company or any of its affiliates (this Agreement and such other plans, policies, arrangements and agreements, the “Company Plans”) to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment. Except as permitted under Section 409A, any deferred compensation (within the meaning of Section 409A) payable to Executive or for Executive’s benefit under any Company Plan may not be reduced by, or offset against, any amount owing by Executive to the Combined Company or any of its affiliates.

(c) Severance benefits under this Agreement are intended to be exempt from Section 409A under the “short-term deferral” exception, to the maximum extent applicable, and then under the “separation pay” exception, to the maximum extent applicable. If, at the time of Executive’s separation from service (within the meaning of Section 409A), (i) Executive shall be a specified employee (within the meaning of Section 409A and using the identification methodology selected by the Combined Company from time to time) and (ii) the Combined Company shall make a good faith determination that an amount payable under a Company Plan constitutes deferred compensation (within the meaning of Section 409A) the payment of which is required to be delayed pursuant to the six-month delay rule set forth in Section 409A in order to avoid taxes or penalties under Section 409A, then the Combined Company (or its affiliate, as applicable) shall not pay such amount on the otherwise scheduled payment date but shall instead accumulate such amount and pay it on the first business day after such six-month period.

(d) Notwithstanding any provision of this Agreement or any other Company Plan to the contrary, in light of the uncertainty with respect to the proper application of Section 409A, the Combined Company reserves the right to make amendments to any Company Plan as the Combined Company deems necessary or desirable to avoid the imposition of taxes or penalties under Section 409A. In any case, Executive is solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on Executive or for Executive’s account in connection with any Company Plan (including any taxes and penalties under Section 409A), and neither the Combined Company nor any affiliate shall have any obligation to indemnify or otherwise hold Executive harmless from any or all of such taxes or penalties.

(e) For purposes of Section 409A, each payment hereunder will be deemed to be a separate payment as permitted under Treasury Regulation Section 1.409A-2(b)(2)(iii). Notwithstanding anything herein to the contrary, to the extent required by Section 409A, Executive shall not be entitled to any payments or benefits payable hereunder as a result of Executive’s termination of employment with the Combined Company that constitute “deferred compensation” under Section 409A unless such termination of employment qualifies as a “separation from service” within the meaning of Section 409A (and any related regulations or other pronouncements thereunder).

(f) Except as specifically permitted by Section 409A, any benefits and reimbursements provided to Executive under this Agreement during any calendar year shall not affect any benefits and reimbursements to be provided to Executive under this Agreement in any other calendar year, and the right to such benefits and reimbursements cannot be liquidated or exchanged for any other benefit. Furthermore, reimbursement payments shall be made to Executive as soon as practicable following the date that the applicable expense is incurred, but in no event later than the last day of the calendar year following the calendar year in which the underlying expense is incurred.

SECTION 6.14. Section 280G. Notwithstanding any other agreement between the Combined Company and Executive, in the event that any payment or benefits provided to Executive (whether made or provided pursuant to this Agreement or otherwise) constitute “parachute payments” within the meaning of Section 280G of the Code (“Parachute Payments”) and would be subject to the tax (the “Excise Tax”) imposed by Section 4999 of the Code, then Executive shall be entitled to receive either (i) the full amount of the Parachute Payments, or (ii) the maximum amount that may be provided to Executive without resulting in any portion of such Parachute Payments being subject to such Excise Tax, whichever of clauses (i) and (ii), after taking into account applicable Federal, state, and local taxes and the Excise Tax, results in the receipt by the Executive, on an after-tax basis, of the greatest portion of the Parachute Payments. Any reduction of the Parachute Payments pursuant to the foregoing shall occur in the following order: (a) any cash payment under any retention bonus agreement or similar agreement, (b) any cash severance payable by reference to Executive’s Base Salary and Annual Bonus, (c) any other cash amount payable to Executive, (d) any benefit valued as a Parachute Payment, and (e) acceleration of vesting of any equity award. Such reduction shall be first applied to payments and benefits in each of the forgoing categories in reverse order beginning with the payments or benefits that are to be paid the furthest in time from the date of such determination. Any determination required under this Section 6.14 shall be made in writing by a nationally recognized public accounting firm designated by public accountants of the Combined Company, whose determination shall be conclusive and binding for all purposes upon the Combined Company and Executive. For purposes of making any calculation required by this Section 6.14, such accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good-faith interpretations concerning the application of Sections 280G and 4999 of the Code.

SECTION 6.15. Counterparts. This Agreement may be executed in any number of counterparts (including by facsimile of PDF), each of which shall be deemed to be an original instrument and all of which together shall constitute a single instrument. If any signature is delivered by facsimile transmission or by PDF, such signature shall create a valid and binding obligation of the party executing (or on whose behalf the signature is executed) with the same force and effect as if such facsimile or PDF signature were an original thereof.

SECTION 6.16. Construction. The headings in this Agreement are for convenience only and shall not control or affect the meaning or construction of any provision of this Agreement. As used in this Agreement, words such as “herein,” “hereinafter,” “hereby” and “hereunder,” and the words of like import refer to this Agreement, unless the context requires otherwise. The words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation”. As used in Article V and VI, the terms the “Combined Company” and the “Company” include the Combined Company or the Company, respectively, and each of their subsidiaries and affiliates and their predecessors, successors and assigns.

WHEREAS, the Company (formerly known as Amazon Holdco Inc.) previously entered into that Agreement and Plan of Merger, dated as of November 20, 2023, by and among Jacobs Solutions Inc., Amentum Parent Holdings LLC and Amentum Joint Venture LP (the “Merger Agreement”), pursuant to which Amentum Parent Holdings LLC merged with and into the Company (such merger, the “Merger”, and the combined company resulting from the Merger, the “Combined Company”);

WHEREAS, effective as of, and following, the Merger, Executive is serving as the Chief Executive Officer of the Combined Company; and

WHEREAS, in connection with the foregoing and the other transactions contemplated by the Merger Agreement, the Company and Executive desire to terminate the Prior Agreement and enter into this Agreement, effective as of the Effective Time (as defined in the Merger Agreement), and to set forth the terms and conditions under which Executive will serve as Chief Executive Officer of the Combined Company.

NOW, THEREFORE, in consideration of the premises and mutual agreements herein contained, the parties hereto do hereby agree as follows:

ARTICLE I

Employment

SECTION 1.01. Term. Subject to the terms of this Agreement, the term of Executive’s employment under this Agreement commenced on the Closing Date (as defined in the Merger Agreement) and shall terminate on the second anniversary of the Closing Date (the “Initial Period”); provided that such term of employment shall automatically renew upon the expiration of the Initial Period and on each subsequent anniversary thereof for one year (“Renewal Period”), unless the Combined Company delivers to Executive, or Executive delivers to the Combined Company, written notice (“Notice of Non-Renewal”) at least 60 days in advance of the expiration of the Initial Period or any Renewal Period that such term of employment shall not be extended, in which case such term of employment shall end at the end of the Initial Period or Renewal Period in which such notice was delivered and shall not be further extended. Notwithstanding the foregoing, Executive’s employment with the Combined Company shall be “at will” and, subject to the provisions of Article IV and the notice requirements set forth above, Executive’s employment under this Agreement may be terminated by the

Combined Company or Executive at any time and for any reason, with or without prior notice.

SECTION 1.02. Position and Duties. During Executive’s term of employment, Executive shall serve as the Chief Executive Officer of the Combined Company reporting to the Board of Directors of the Combined Company (the “Board”), performing duties and having responsibilities customary for the chief executive officer of similar companies. Executive shall perform such services and duties in accordance with the policies, practices and bylaws of the Combined Company. During Executive’s term of employment, Executive shall also serve as a member of the Board and may also be appointed to committees and the board of directors or other managing body of the Combined Company’s subsidiaries or affiliates and their committees. Executive shall not be entitled to any additional compensation for such service. For all purposes, any action to be taken, or determination to be made by, the Board under this Agreement may also be made by a duly authorized committee of the Board.

SECTION 1.03. Time and Effort. Executive shall serve the Combined Company faithfully, loyally, honestly and to the best of Executive’s ability. Executive shall devote all of Executive’s business time and best efforts to the performance of Executive’s duties on behalf of the Combined Company and its subsidiaries and affiliates. During Executive’s term of employment, Executive shall not at any time or place or to any extent whatsoever, either directly or indirectly, without the express written consent of the Board, engage in any outside employment or in any activity that, in the reasonable judgment of the Combined Company, is competitive with or adverse to the business, practice or affairs of the Combined Company or any of its affiliates, whether or not such activity is pursued for gain, profit or other pecuniary advantage. Notwithstanding the foregoing, it shall not be a violation of this Agreement for Executive to (i) serve as a director of charitable organizations to the extent such service has been approved by the Board (such approval not to be unreasonably withheld) or (ii) continue to serve on the board of directors of the entities set forth on Schedule A hereto.

ARTICLE II

Compensation

reviews. In the event that sickness or disability payments under any insurance programs of the Combined Company or otherwise shall become payable to Executive in respect of any period of Executive’s employment under this Agreement, the salary installment payable to Executive hereunder on the next succeeding salary installment payment date shall be an amount computed by subtracting (a) the amount of such sickness or disability payments that shall have become payable during the period between such date and the immediately preceding salary installment date from (b) the salary installment otherwise payable to Executive hereunder on such date.

SECTION 2.02. Annual Bonus. During the term of Executive’s employment under this Agreement, Executive shall be eligible to participate in the annual incentive compensation plans of the Combined Company, as may be continued or established by the Board for similarly situated executives, in its discretion, from time to time, and shall have the opportunity to earn a performance-based cash bonus (“Annual Bonus”) with a target Annual Bonus of 140% of Base Salary for the fiscal year to which such Annual Bonus relates.

SECTION 2.03. Long-Term Incentive Awards. During the term of Executive’s employment under this Agreement, Executive shall be eligible to participate in the long-term incentive compensation plans of the Combined Company as in effect from time to time on a basis, including with respect to grant date values and terms and conditions, as determined by the Board, consistent with Executive’s roles and duties.

ARTICLE III

Executive Benefits

SECTION 3.01. Benefit Plans. During the term of Executive’s employment under this Agreement, Executive shall be entitled to participate in any benefit plans (excluding severance, bonus, incentive or profit-sharing plans) offered by the Combined Company as in effect from time to time (collectively, “Benefit Plans”) on the same basis as that generally made available to other employees of the Combined Company to the extent Executive may be eligible to do so under the terms of any such Benefit Plan. Executive understands that any such Benefit Plans may be terminated or amended from time to time by the Combined Company in its discretion. Notwithstanding the first sentence of this Section 3.01, nothing shall preclude Executive from participating during the term of Executive’s employment under this Agreement in any present or future bonus, incentive or profit-sharing plan or other plan of the Combined Company for the benefit of its employees, in each case as and to the extent approved or determined by the Board in its discretion and subject to the other terms of this Agreement.

Combined Company adequate records and other documentary evidence required to substantiate such expenditures. The Company shall promptly reimburse Executive up to $25,000 in attorneys’ fees incurred by him in connection with the entry into this Agreement; provided that Executive furnishes to the Company adequate records and other documentary evidence required to substantiate such attorneys’ fees.

SECTION 3.03. Vacation. During the term of Executive’s employment under this Agreement, Executive shall receive paid vacation days in accordance with the Combined Company’s vacation policy based on Executive’s tenure with the Combined Company.

ARTICLE IV

Termination

SECTION 4.01. Exclusive Rights. The amounts payable under this Article IV and pursuant to any applicable award agreement under which the long-term incentive awards will be granted are intended to be, and are, exclusive and in lieu of any other rights or remedies to which Executive may otherwise be entitled, including under common, tort or contract law, under policies of the Combined Company and its affiliates in effect from time to time, under this Agreement or otherwise, in the event of Executive’s termination of employment with the Combined Company and its affiliates; provided that, notwithstanding the foregoing, Executive shall be entitled to participate, and receive benefits under, the Amentum Holdings, Inc. Severance Plan for Key Employees in accordance with its terms.

SECTION 4.02. Termination by The Company for Cause; Termination by Executive without Good Reason. (a) If the Combined Company terminates Executive for Cause or if Executive elects to terminate Executive’s employment with the Combined Company without Good Reason, Executive shall be entitled to receive (i) Base Salary earned through the date of termination that remains unpaid as of the date of Executive’s termination, (ii) any Annual Bonus for any previously completed bonus period that has been earned and remains unpaid as of the date of Executive’s termination, (iii) reimbursement for any unreimbursed business expenses properly incurred by Executive prior to the date of Executive’s termination to the extent such expenses are reimbursable under Section 3.02 and (iv) such benefits (excluding benefits under any severance plan, program or policy then in effect), if any, to which Executive may be entitled under the Benefit Plans as of the date of Executive’s termination, which benefits shall be payable in accordance with the terms of such Benefit Plans (the amounts described in clauses (i) through (iv) of this Section 4.02(a) being referred to herein as the “Accrued Rights”).

(b) For purposes of this Agreement, the term “Cause” shall mean Executive’s:

(i) intentional failure to perform reasonably assigned duties;

(ii) personal dishonesty or willful misconduct in the performance of duties, which causes or threatens to cause material injury to the Combined Company or any of its affiliates, including any reputational harm;

(iii) breach of fiduciary duties owed by Executive to the Combined Company or any of its affiliates resulting in personal profit to Executive;

(iv) willful violation of any law, rule or regulation in connection with the performance of duties (other than traffic violations or similar offenses);

(v) material failure to comply with the Combined Company’s code of conduct or employment practices;

(vi) material breach of any of the terms contained in this Agreement or similar type of agreement to which Executive is a party; or

(vii) any act by Executive involving (A) fraud, (B) any breach by Executive of applicable regulations of competent authorities in relation to trading or dealing with stocks, securities, or investments or (C) any willful or grossly negligent act by the Executive resulting in an investigation by the Securities and Exchange Commission (the “SEC”) or other governmental authority, which, in each of cases (A), (B) and (C) above, the Board determines in its reasonable and good faith discretion materially adversely affects the Combined Company or any of its affiliates or Executive’s ability to perform his duties hereunder.

For purposes of this definition, an act, or failure to act, on Executive’s part shall be deemed “willful” if done, or omitted to be done, by Executive intentionally, in bad faith and without reasonable belief that the action or omission was in the best interest of the Combined Company. If the Combined Company desires to terminate Executive’s employment for Cause in the case of any prong other than clause (iv) of Section 4.02(b) and the basis for Cause, by its nature, is capable of being cured, the Combined Company shall first provide Executive with written notice of the applicable event that constitutes the basis for Cause (a “Cause Notice”) within ten days of the Board becoming aware of such event. Such notice shall specifically identify such claimed breach. Executive shall have 15 days following receipt of such Cause Notice (the “Cause Cure Period”) to cure such basis for Cause, and the Combined Company shall be entitled at the end of such Cause Cure Period to terminate Executive’s employment under this Agreement for Cause; provided, however, that, if such breach is cured within the Cause Cure Period or if the Combined Company does not terminate Executive’s employment with the Combined Company within ten days after the end of the Cause Cure Period, the Combined Company shall not be entitled to terminate Executive’s

employment for Cause based on the event described in the Cause Notice and; provided further that notwithstanding the foregoing, Executive will not be entitled to cure a particular basis for Cause more than once during any six-month period.

(c) For purposes of this Agreement, the term “Good Reason” shall mean any of the following actions, without Executive’s express prior written approval:

(i) any material reduction in Executive’s Base Salary or target Annual Bonus opportunity;

(ii) subject to the terms and conditions of the applicable plan(s), any failure by the Combined Company to continue to provide retirement, fringe and welfare benefits to Executive that are substantially similar in the aggregate to those afforded to senior executives of the Combined Company;

(iii) any material adverse change in Executive’s duties or responsibilities, including any change in Executive’s reporting relationships such that he no longer reports to the Board (or any successors to such board);

(iv) any relocation of Executive’s principal place of business of 50 miles or more, unless Executive is permitted to work remotely;

(v) any delivery to Executive by the Board of a Notice of Non-Renewal; or

(vi) any failure to pay Executive’s Base Salary and other amounts earned by Executive within ten days after the date such compensation is due.

(d) Executive must provide written notice to the Combined Company pursuant to Section 6.05 of this Agreement of Executive’s intent to resign for Good Reason within 45 days of the occurrence of an event described in Section 4.02(c) above (each, a “Good Reason Event”) in order for Executive’s resignation for Good Reason to be effective hereunder. Upon receipt of such notice, the Combined Company shall have 30 days (60 days in the case of the Good Reason Event described in Section 4.02(c)(v) above) (the applicable period, the “Good Reason Cure Period”) to rectify the Good Reason Event. If the Combined Company fails to rectify the Good Reason Event prior to the expiration of the Good Reason Cure Period, then Executive may terminate employment within 10 days following the expiration of the Good Reason Cure Period and such termination will be considered for Good Reason and, in the event Executive’s termination is in respect of the Good Reason Event described in Section 4.02(c)(v) above, such termination will be considered for Good Reason for all purposes of this Agreement notwithstanding the earlier expiration of the term of Executive’s employment under this Agreement.

SECTION 4.03. Termination by The Company Other Than for Cause, Disability or Death; Termination by Executive for Good Reason. If the Combined Company elects to terminate Executive’s employment for any reason other than Cause, Disability (as defined below) or death, or if Executive terminates Executive’s employment with the Combined Company for Good Reason, Executive shall be entitled to the Accrued Rights and; provided that Executive has provided a general release in favor of the Combined Company and its subsidiaries and affiliates, and their respective directors, officers, employees, agents and representatives in form and substance reasonably acceptable to the Combined Company (the “Release”) and the Release has become effective and irrevocable prior to the 60th day after such termination of employment, Executive shall be entitled to the following:

(a) Cash Payments. (i) The Combined Company shall pay to Executive an amount equal to 1.5 times the sum of Executive’s then-current Base Salary and “Average Bonus” (as defined below), payable in equal installments through the date that is 18 months after the date of Executive’s termination of employment (the “Severance Period”) at the same times at which and in the same manner in which Executive’s Base Salary would have been payable to Executive had a termination of employment not occurred and (ii) the Combined Company shall provide to Executive, during the calendar year following the calendar year in which Executive’s termination of employment occurs, an Annual Bonus for the fiscal year in which the termination occurs equal to the Annual Bonus that Executive would have received if his employment had not terminated prior to the end of the fiscal year (e.g., after determining whether applicable performance goals have been achieved, determined on a basis consistent with past practice), pro-rated based on a fraction, the numerator of which shall equal the number of days Executive was employed by the Combined Company in the fiscal year in which Executive’s termination occurs and the denominator of which shall equal 365 (the “Pro-Rata Bonus”); provided, however, that, in the case of clause (i), the Combined Company shall (x) commence such payments on the 60th day after termination of Executive’s employment, except that any payments that would have otherwise been paid to Executive following the date of the termination of employment and prior to such 60th day shall be accumulated and paid to Executive in a lump sum on the first payment date following such 60th day, and (y) not continue such payments at any time following either (A) breach of the provisions of Section 5.03 or 5.04 or (B) breach of the provisions of Article V (other than Section 5.03 or 5.04) that (X) is materially damaging to the business or reputation of the Combined Company or any of its affiliates or (Y) occurs after the Combined Company has notified Executive more than once of a prior breach of such Article V (other than Section 5.03 or 5.04). For purposes of this Agreement, “Average Bonus” means the average of all Annual Bonuses paid or payable to Executive in respect of the three fiscal years ended prior to the fiscal year in which the employment of Executive is terminated (or, if Executive was not employed by the Combined Company during each of such fiscal years, such lesser number of fiscal years during which Executive was so employed); provided that for purposes of calculating “Average Bonus”, (i) any pro-rated Annual Bonus awarded to Executive for a fiscal year in which Executive was employed for less than the full fiscal year shall be annualized, (ii) the Annual Bonus for the last of the three fiscal

years utilized in this calculation shall be disregarded (and Executive shall be treated as if he were not employed during such fiscal year) if the Annual Bonus for that year (A) has not been paid because Executive was terminated prior to the scheduled date for payment of such Annual Bonus or (B) was paid based on an adverse change to Executive’s target Annual Bonus and (iii) for purposes of the calculation of the Average Bonus, any annual bonuses received by Executive from the Company shall be considered as if it was an Annual Bonus under this Agreement.

(b) Medical, Dental, Life Insurance and Financial Services Benefit Continuation. During the Severance Period, Executive and Executive’s spouse and dependents (each as defined under the applicable program) shall receive the following benefits if Executive timely and properly elects continued coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”): (x) a lump sum cash payment in amount sufficient to cover the total amount of the monthly medical and dental insurance premiums payable during the Severance Period to continue medical and dental insurance coverage at the same benefit levels as provided to active senior executives of the Combined Company immediately prior to such termination of employment; (y) a monthly cash payment grossed up for taxes to permit Executive to purchase life insurance coverage at the same benefit level as currently provided to active senior executives of the Combined Company and at the same cost to Executive as is generally provided to active senior executives of the Combined Company; and (z) a lump sum cash payment in an amount sufficient to cover, during the Severance Period, the annual premium that would be payable by Executive for the continued receipt of financial planning services which Executive receives as of immediately prior to such termination of employment. Notwithstanding any provision of this Agreement to the contrary, to the extent necessary to satisfy Section 105(h) of the Internal Revenue Code of 1986, as amended (the “Code”), or if the Combined Company determines is necessary to avoid the imposition of an excise tax on the Combined Company, the Combined Company will be permitted to alter the manner in which medical and dental benefits are provided to Executive following termination of Executive’s employment; provided that the after-tax cost to Executive of such benefits shall not be greater than the cost applicable to similarly situated executives of the Combined Company who have not terminated employment.

(d) Release. For the avoidance of doubt, (x) the Release shall not require Executive to release any rights to post-termination payments or benefits afforded to him

by this Agreement, or any vested benefits or rights pursuant to the terms of the Combined Company’s and its affiliates’ benefit plans or programs, or to any rights related to his ownership of fully vested equity securities of the Combined Company, and (y) if the Release does not become effective and irrevocable within 60 days following the date of Executive’s termination of employment pursuant to this Section 4.03(d), the Combined Company shall not be obligated to make any payments or provide any benefits under Section 4.03(a), (b) or (c) above and Executive shall only be entitled to the Accrued Rights.

SECTION 4.04. Termination for Disability or Death. Executive’s employment shall terminate automatically upon Executive’s death. The Combined Company may terminate Executive’s employment upon the occurrence of Executive’s Disability. In the event of Executive’s termination due to death or Disability, Executive, or Executive’s estate, as the case may be, shall be entitled to receive the Accrued Rights and the Pro-Rata Bonus during the calendar year following the calendar year in which Executive’s termination of employment occurs. For purposes of this Agreement, the term “Disability” shall mean (a) the inability of Executive, due to illness, accident or any other physical or mental incapacity, to perform Executive’s duties in a normal manner for a period of 180 days (whether or not consecutive) in any twelve-month period during the term of Executive’s employment under this Agreement or (b) Executive being accepted for long-term disability benefits under any long-term disability plan in which he is then participating. The Board shall determine, according to the facts then available, whether and when the Disability of Executive has occurred. Such determination shall not be arbitrary or unreasonable and the Board will take into consideration the expert medical opinion of a physician chosen by the Combined Company, after such physician has completed an examination of Executive. Executive agrees to make himself available for such examination upon the reasonable request of the Combined Company.
