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 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 Financial Officer of the Combined Company reporting to the Chief Executive Officer of the Combined Company, performing duties and having responsibilities customary for the chief financial officer of similar companies. Executive shall perform such services and duties in accordance with the policies, practices and bylaws of the Combined Company.

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 of Directors of the Combined Company (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 serve as a director of charitable organizations to the extent such service has been approved by the Board.

ARTICLE II

Compensation

SECTION 2.01. Base Salary. During the term of Executive’s employment under this Agreement, the Combined Company shall, as compensation for the obligations set forth herein and for all services rendered by Executive in any capacity during Executive’s employment under this Agreement, including services as an officer, employee, director or member of any governing body, or committee thereof, of the Combined Company or any of its affiliates, pay Executive a base salary (“Base Salary”) at the annual rate of $650,000 per year, payable in substantially equal installments in accordance with the Combined Company’s standard payroll practices as in effect from time to time. The Combined Company shall review Executive’s performance at least annually and may increase but not decrease his Base Salary in connection with such 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 2.03. 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.

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 Chief Executive Officer; or

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

(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 (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.

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.

(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) 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.

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.

Executive has not prior to the Closing Date, whether in writing or orally, criticized or disparaged the Combined Company, nor shall Executive during the period commencing on the Closing Date and terminating five years after the date of Executive’s termination of employment with the 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 5.12. Notification of Subsequent Employer.

ARTICLE VI

Miscellaneous

SECTION 6.01. Assignment. This Agreement shall not be assignable by Executive. The parties agree that any attempt by Executive to delegate Executive’s duties hereunder shall be null and void. This Agreement may be assigned by the Combined Company to a person or entity that is an affiliate or a successor in interest to substantially all the business operations of the Combined Company. Upon such assignment, the rights and obligations of the Combined Company hereunder shall become the rights and obligations of such affiliate or successor person or entity. As used in this Agreement, the term the “Combined Company” shall mean the Combined Company as hereinbefore defined in the recital to this Agreement and any permitted assignee to which this Agreement is assigned.

SECTION 6.02. Successors. This Agreement shall be binding upon and shall inure to the benefit of the successors and permitted assigns of the Combined Company and the personal or legal representatives, executors, administrators, successors, distributees, devisees and legatees of Executive. Executive acknowledges and agrees that all Executive’s covenants and obligations to the Combined Company, as well as the rights of the Combined Company under this Agreement, shall run in favor of and will be enforceable by the Combined Company, its subsidiaries and its successors and permitted assigns.

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, Alexandria Division, 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.
