“Prior Agreement”); 
 WHEREAS, PAE desires to continue to employ Executive, and Executive desires to continue such
employment and enter into this Agreement, which sets forth the terms and conditions under which Executive will continue to serve PAE, effective as of the Effective Date; and 

WHEREAS, the parties acknowledge that the terms of this Agreement shall, upon the Effective Date, replace and supersede the Prior Agreement,
which will thereupon become null and void. 
 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. The term of Executive’s employment under this Agreement shall commence on the Effective Date and shall terminate on the second anniversary of the Effective 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 PAE delivers to Executive, or Executive delivers to PAE,
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 PAE 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 PAE or Executive at any time and for any reason, with or without prior notice.

 SECTION 1.02. Position and Duties. During the term of this Agreement, Executive shall serve as the Chief Financial Officer of PAE
reporting to the Chief Executive Officer of PAE, performing duties and having responsibilities customary for such position and as may from time to time be assigned to Executive by the Chief Executive Officer of PAE. Executive shall perform such
services and duties in accordance with the policies, practices and bylaws of PAE. 

 SECTION 1.03. Time and Effort. Executive shall serve PAE 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 PAE. 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 or other governing body of PAE (the “Board”), engage in any outside employment
or in any activity that, in the reasonable judgment of PAE, is competitive with or adverse to the business, practice or affairs of PAE 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 (such approval not to be unreasonably withheld).

 ARTICLE II 
 Compensation

 SECTION 2.01. Base Salary. During the term of Executive’s employment under this Agreement, PAE 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 PAE or any of its affiliates, pay Executive a base salary (“Base Salary”) at the annual rate of $512,000 per year, payable in substantially equal installments in accordance with PAE’s standard payroll practices as
in effect from time to time. In the event that sickness or disability payments under any insurance programs of PAE 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 PAE, as may be continued or established by the Board, in its discretion, from time to time (the “Bonus Plan”) and shall have the opportunity to earn a performance-based bonus
(“Annual Bonus”) targeted at 75% of Executive’s Base Salary (“Target Bonus”) and a maximum bonus opportunity for above-target performance of up to 200% of Executive’s Target Bonus for the fiscal year to
which such Annual Bonus relates. The performance goals and Annual Bonus payable for a given fiscal year under the Bonus Plan shall be determined by the Board. Except as provided in Article IV, payment of the Annual Bonus will be conditioned upon
Executive’s continued employment though the payment date.

 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 PAE as in effect from time to time (collectively, “Benefit Plans”) on the same basis as that generally made available to
other employees of PAE 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 PAE 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 PAE 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 3.02. Business Expenses. PAE will reimburse Executive for all reasonably incurred business expenses, subject to the travel and
expense policy established by PAE from time to time, incurred by Executive during the term of Executive’s employment under this Agreement in the performance of Executive’s duties hereunder; provided that Executive furnishes to PAE
adequate records and other documentary evidence required to substantiate such expenditures. 
 SECTION 3.03. Vacation. During the
term of Executive’s employment under this Agreement, Executive shall receive not less than 25 paid vacation days per year, which shall be accrued and taken in accordance with PAE’s vacation policy. 

ARTICLE IV 
 Termination

 SECTION 4.01. Exclusive Rights. The amounts payable under this Article IV 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 PAE and its affiliates in effect from time to time, under this Agreement or otherwise, in the event of
Executive’s termination of employment with PAE and its affiliates. 
 SECTION 4.02. Termination by PAE for Cause; Termination by
Executive without Good Reason. (a) If PAE terminates Executive for Cause or if Executive elects to terminate Executive’s employment with PAE 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 

  
 3 

 
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 Benefits 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 PAE or any
of its affiliates; 
 (iii) breach of fiduciary duties owed by Executive to PAE 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); or 
 (v) 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,
which, in each of cases (a), (b) and (c) above, the Board determines in its reasonable and good faith discretion materially adversely affects PAE 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 PAE. If PAE desires to terminate Executive’s employment for Cause in the case of clauses (i), (ii),
(iii) or (v) of Section 4.02(b) and the basis for Cause, by its nature, is capable of being cured, PAE 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 PAE 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 PAE does not terminate Executive’s employment with PAE within ten days after the end of the Cause Cure Period, PAE 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 the opportunity to cure a particular basis for Cause more than once during any six-month period. 

  
 4 

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

(iii) any material adverse change in Executive’s duties or responsibilities; 

(iv) any relocation of Executive’s principal place of business of 50 miles or more, provided that such relocation also increases
Executive’s commute by at least 25 miles; 
 (v) any delivery to Executive by PAE 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 PAE 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, PAE 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 PAE 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 PAE Other Than for Cause, Disability or Death; Termination by Executive for Good Reason. If PAE 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 PAE for Good Reason, Executive shall be entitled to the Accrued Rights and,
provided that Executive has provided a general release in favor of PAE, PAE Holding, Parent and their subsidiaries and affiliates, and their respective directors, officers, employees, agents and representatives in form and substance reasonably
acceptable to PAE (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) PAE shall pay to Executive an amount equal to Executive’s then-current Base Salary, payable in
installments through the date that is 12 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 

  
 5 

 
payable to Executive had a termination of employment not occurred and (ii) PAE 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 PAE 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), PAE 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 PAE or any of its
affiliates or (Y) occurs after PAE has notified Executive of a prior breach of such Article V (other than Section 5.03 or 5.04). 

(b) Medical and Dental Insurance Benefit Continuation. During the Severance Period, Executive and Executive’s spouse and dependents
(each as defined under the applicable program) shall receive medical and dental insurance coverage at the same benefit levels as provided to active senior management employees of PAE, for which PAE will (A) reimburse Executive during the
Severance Period, for the total amount of the monthly medical and dental insurance premiums payable by Executive for continued benefits coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, in excess of the
cost Executive paid for such coverage (on a monthly premium basis) immediately prior to such termination of employment and (B) provide such coverage for any remaining portion of the Severance Period at the same cost to Executive as is generally
provided to active senior management employees of PAE (or, if it is not possible, or is cost-prohibitive for PAE to provide such coverage for such remaining portion, PAE will pay Executive an additional monthly amount, at the same time as cash
severance payments are made pursuant to Section 4.03(a), of cash equal to the premiums PAE would have paid if Executive had remained an active employee, subject to Section 6.13 hereof); provided, however, that if, during the
Severance Period, Executive becomes employed by a new employer that provides medical and dental coverage, PAE’s continuing medical and dental coverage (and any cash payments in lieu thereof) shall become secondary to such new employer’s
coverage with respect to claims covered by such new employer’s medical and dental plans. 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 PAE determines is necessary to avoid the imposition of an excise tax on PAE, PAE 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 PAE who have
not terminated employment. 

  
 6 

 (c) 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 PAE’s or its affiliates’ benefit plans or programs, 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(c), PAE shall not be obligated to make any payments or provide any benefits under
Section 4.03(a) or (b) 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. PAE 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 PAE, after such physician has completed an examination of Executive. Executive agrees to make himself
available for such examination upon the reasonable request of PAE.

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 PAE to a person or entity that is an affiliate or a successor in interest to substantially all the business operations of PAE. Upon such
assignment, the rights and obligations of PAE hereunder shall become the rights and obligations of such affiliate or successor person or entity. As used in this Agreement, the term “PAE” shall mean PAE 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

 SECTION 6.03. Entire Agreement. This Agreement constitutes the entire agreement and understanding of the parties and with respect
to the transactions contemplated hereby and subject matter hereof and supersedes and replaces any and all prior agreements (including the Prior Agreement), understandings, statements, representations and warranties, written or oral, express or
implied and/or whenever and howsoever made, directly or indirectly relating to the subject matter hereof. Notwithstanding the above, Executive’s covenants set forth in Article V shall operate independently of, and shall be in addition to, any
similar covenants to which Executive is subject pursuant to any other agreement with PAE or any of PAE’s affiliates.

 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 State of New York, 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, tortuous
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 Arlington 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). 

  
 12 

 (c) Each party in any dispute or legal action arising under this Agreement shall be
responsible for bearing its own expenses, attorneys’ fees and other costs in such dispute or 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 PAE 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 PAE, to the extent
necessary to preserve the intended benefits of such provisions. 
 SECTION 6.09. Cooperation. Executive shall provide
Executive’s reasonable cooperation to PAE in connection with any suit, action or proceeding (or any appeal therefrom) that relates to events occurring during Executive’s employment with PAE or any of its affiliates other than a suit
between Executive, on the one hand, and PAE, on the other hand, provided that PAE shall reimburse Executive for expenses reasonably incurred in connection with such cooperation. 

SECTION 6.10. Executive Representation. Executive hereby represents to PAE that the execution and delivery of this Agreement by
Executive and PAE and the performance by Executive of Executive’s duties hereunder shall not constitute a breach of, or otherwise contravene, or be prevented, interfered with or hindered by, the terms of any employment agreement or other
agreement or policy to which Executive is a party or otherwise bound. 
 SECTION 6.11. 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 6.12. Set Off. PAE’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 PAE or its affiliates, except as provided in Section 6.14.

  
 13 

 SECTION 6.13. Withholding Taxes. PAE 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 6.14. Section 409A. (a) It is intended that the provisions of this Agreement comply with
Section 409A (“Section 409A”) of the Code, 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 PAE 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 PAE or any of its affiliates. 

(c) 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 PAE from time to time) and (ii) PAE 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 PAE (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 Company Plan to the
contrary, in light of the uncertainty with respect to the proper application of Section 409A, PAE reserves the right to make amendments to any Company Plan as PAE 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 PAE 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, Executive shall not be entitled to any payments or benefits payable hereunder as a result of Executive’s termination of
employment with PAE 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), 

  
 14 

 (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 6.15. 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. (a) 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. 
 (b) 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”. 
 (c) As used in Articles V and VI, the term “PAE” includes
PAE and its subsidiaries and affiliates and their predecessors, successors and assigns.

 Exhibit 10.26 

EMPLOYMENT AGREEMENT (this “Agreement”) dated as of March 14, 2016 (the “Effective Date”), by and
between PAUL W. COBB (“Executive”) and PACIFIC ARCHITECTS AND ENGINEERS INCORPORATED, a California corporation (“PAE”). 

WHEREAS, PAE has entered into that certain Agreement and Plan of Merger, dated as of January 14, 2016 (the “Merger
Agreement”), by and among (i) PAE Holding Corporation (“PAE Holding”), (ii) LG PAE, L.P., (iii) Shay Intermediate Holding II Corporation (“Parent”) and (iv) Shay Merger Corporation
(“Sub”), pursuant to which Sub will merge with and into PAE Holding, with PAE Holding continuing as the surviving corporation, subject to the terms and conditions of the Merger Agreement; 

WHEREAS, PAE has employed Executive pursuant to that certain letter agreement, dated as of August 3, 2015 (the “Prior
Agreement”); 
 WHEREAS, PAE and Executive are party to a Retention Agreement, dated September 9, 2015 (as amended, the
“Retention Agreement”); 
 WHEREAS, PAE desires to continue to employ Executive, and Executive desires to continue such
employment and enter into this Agreement, which sets forth the terms and conditions under which Executive will continue to serve PAE, effective as of the Effective Date; and 

WHEREAS, the parties acknowledge that the terms of this Agreement shall, upon the Effective Date, replace and supersede the Prior Agreement,
which will thereupon become null and void. 
 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. The term of Executive’s employment under this Agreement shall commence on the Effective Date and shall terminate on the second anniversary of the Effective 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 PAE delivers to Executive, or Executive delivers to PAE,
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 PAE 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 PAE or Executive at any time and for any reason, with or without prior notice.

 SECTION 1.02. Position and Duties. During the term of this Agreement, Executive shall
serve as the Senior Vice President and General Counsel of PAE reporting to the Chief Executive Officer of PAE, performing duties and having responsibilities customary for such position and as may from time to time be assigned to Executive by the
Chief Executive Officer of PAE. Executive shall perform such services and duties in accordance with the policies, practices and bylaws of PAE. 

SECTION 1.03. Time and Effort. Executive shall serve PAE 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 PAE. 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 or other governing body of PAE (the “Board”), engage in any outside employment or in any activity that, in the reasonable
judgment of PAE, is competitive with or adverse to the business, practice or affairs of PAE 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 (such approval not to be unreasonably withheld). 

ARTICLE II 
 Compensation

 SECTION 2.01. Base Salary. During the term of Executive’s employment under this Agreement, PAE 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 PAE or any of its affiliates, pay Executive a base salary (“Base Salary”) at the annual rate of $387,000 per year, payable in substantially equal installments in accordance with PAE’s standard payroll practices as
in effect from time to time. In the event that sickness or disability payments under any insurance programs of PAE 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 PAE, as may be continued or established by the Board, in its discretion, from time to time (the “Bonus Plan”) and shall have the opportunity to earn a performance-based bonus
(“Annual Bonus”) targeted at 75% of Executive’s Base Salary (“Target Bonus”) and a maximum bonus opportunity for above-target performance of up to 200% of Executive’s Target Bonus for the fiscal year to
which such Annual Bonus relates. The performance goals and Annual Bonus payable for a given fiscal year under the Bonus Plan shall be determined by the Board. Except as provided in Article IV, payment of the Annual Bonus will be conditioned upon
Executive’s continued employment though the payment date. 

  
 2 

 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 PAE as in effect from time to time (collectively, “Benefit Plans”) on the same basis as that generally made available to
other employees of PAE 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 PAE 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 PAE 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 3.02. Business Expenses. PAE will reimburse Executive for all reasonably incurred business expenses, subject to the travel and
expense policy established by PAE from time to time, incurred by Executive during the term of Executive’s employment under this Agreement in the performance of Executive’s duties hereunder; provided that Executive furnishes to PAE
adequate records and other documentary evidence required to substantiate such expenditures. 
 SECTION 3.03. Vacation. During the
term of Executive’s employment under this Agreement, Executive shall receive not less than 25 paid vacation days per year, which shall be accrued and taken in accordance with PAE’s vacation policy. 

ARTICLE IV 
 Termination

 SECTION 4.01. Exclusive Rights. The amounts payable under this Article IV 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 PAE and its affiliates in effect from time to time, under this Agreement or otherwise, in the event of
Executive’s termination of employment with PAE and its affiliates. 
 SECTION 4.02. Termination by PAE for Cause; Termination by
Executive without Good Reason. (a) If PAE terminates Executive for Cause or if Executive elects to terminate Executive’s employment with PAE 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, 

  
 3 

 
(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 Benefits 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 PAE or any
of its affiliates; 
 (iii) breach of fiduciary duties owed by Executive to PAE 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); or 
 (v) 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,
which, in each of cases (a), (b) and (c) above, the Board determines in its reasonable and good faith discretion materially adversely affects PAE 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 PAE. If PAE desires to terminate Executive’s employment for Cause in the case of clauses (i), (ii),
(iii) or (v) of Section 4.02(b) and the basis for Cause, by its nature, is capable of being cured, PAE 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 PAE 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 PAE does not terminate Executive’s employment with PAE within ten days after the end of the Cause Cure Period, PAE 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 the opportunity to cure a particular basis for Cause more than once during any six-month period. 

  
 4 

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

(iii) any material adverse change in Executive’s duties or responsibilities; 

(iv) any relocation of Executive’s principal place of business of 50 miles or more, provided that such relocation also increases
Executive’s commute by at least 25 miles; 
 (v) any delivery to Executive by PAE 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 PAE 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, PAE 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 PAE 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 PAE Other Than for Cause, Disability or Death; Termination by Executive for Good Reason. If PAE 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 PAE for Good Reason, Executive shall be entitled to the Accrued Rights and,
provided that Executive has provided a general release in favor of PAE, PAE Holding, Parent and their subsidiaries and affiliates, and their respective directors, officers, employees, agents and representatives in form and substance reasonably
acceptable to PAE (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: 

  
 5 

 (a) If such termination occurs on or before January 1, 2017: 

(i) Cash Payment. PAE shall pay to Executive a lump-sum cash payment in an amount equal to 1.5
times the sum of Executive’s Base Salary (at the rate in effect on the Effective Date or the date of Executive’s termination of employment, whichever is greater) and Executive’s then-current Target Bonus, which amount will be paid on
or following the date the Release becomes effective and in no event later than 65 days following the date of such termination. 
 (ii)
Medical and Dental Insurance Benefit Continuation. For the 18 months after the date of Executive’s termination of employment or, if earlier, the date on which Executive becomes employed by a new employer that maintains a major medical
plan, Executive and Executive’s spouse and dependents (each as defined under the applicable program) may elect to continue to participate in PAE’s medical and dental plans at the level provided to similarly situated active employees of PAE
at PAE’s sole expense pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”); provided that Executive timely elects COBRA continuation coverage in connection with his 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 PAE determines is necessary to
avoid the imposition of an excise tax on PAE, PAE 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 such alteration shall
not increase the after-tax cost to Executive of such benefits. 
 (iii) Retention Bonus. PAE
will pay the unpaid portion of your Bonus (as defined in the Retention Agreement) to you in a lump-sum within 30 days following the date of such termination, which amount will be paid without regard to any
requirement that you execute the Release. 
 (b) If such termination occurs after January 1, 2017: 

(i) Cash Payments. (i) PAE shall pay to Executive an amount equal to Executive’s then-current Base Salary, payable in
installments through the date that is 12 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) PAE 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 PAE 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

  
 6 

 
case of clause (i), PAE 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 PAE
or any of its affiliates or (Y) occurs after PAE has notified Executive of a prior breach of such Article V (other than Section 5.03 or 5.04). 

(ii) Medical and Dental Insurance Benefit Continuation. During the Severance Period, Executive and Executive’s spouse and
dependents (each as defined under the applicable program) shall receive medical and dental insurance coverage at the same benefit levels as provided to active senior management employees of PAE, for which PAE will (A) reimburse Executive during
the Severance Period, for the total amount of the monthly medical and dental insurance premiums payable by Executive for continued benefits coverage pursuant to the COBRA, in excess of the cost Executive paid for such coverage (on a monthly premium
basis) immediately prior to such termination of employment and (B) provide such coverage for any remaining portion of the Severance Period at the same cost to Executive as is generally provided to active senior management employees of PAE (or,
if it is not possible, or is cost-prohibitive for PAE to provide such coverage for such remaining portion, PAE will pay Executive an additional monthly amount, at the same time as cash severance payments are made pursuant to Section 4.03(b)(i),
of cash equal to the premiums PAE would have paid if Executive had remained an active employee, subject to Section 6.13 hereof); provided, however, that if, during the Severance Period, Executive becomes employed by a new employer
that provides medical and dental coverage, PAE’s continuing medical and dental coverage (and any cash payments in lieu thereof) shall become secondary to such new employer’s coverage with respect to claims covered by such new
employer’s medical and dental plans. Notwithstanding any provision of this Agreement to the contrary, to the extent necessary to satisfy Section 105(h) of the Code, or if PAE determines is necessary to avoid the imposition of an excise tax
on PAE, PAE 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 PAE who have not terminated employment. 

(c) 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 PAE’s or its affiliates’ benefit plans or programs, 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(c), PAE shall not be obligated to make any payments or provide any benefits under Section 4.03(a) or (b) above and Executive
shall only be entitled to the Accrued Rights. 

  
 7 

 SECTION 4.04. Termination for Disability or Death. Executive’s employment shall
terminate automatically upon Executive’s death. PAE 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 PAE, after such physician has completed an examination of Executive. Executive agrees to make himself available for such examination upon the reasonable
request of PAE. 
 ARTICLE V

responsible for bearing its own expenses, attorneys’ fees and other costs in such dispute or 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 PAE 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 PAE, to the extent
necessary to preserve the intended benefits of such provisions. 
 SECTION 6.09. Cooperation. Executive shall provide
Executive’s reasonable cooperation to PAE in connection with any suit, action or proceeding (or any appeal therefrom) that relates to events occurring during Executive’s employment with PAE or any of its affiliates other than a suit
between Executive, on the one hand, and PAE, on the other hand, provided that PAE shall reimburse Executive for expenses reasonably incurred in connection with such cooperation. 

SECTION 6.10. Executive Representation. Executive hereby represents to PAE that the execution and delivery of this Agreement by
Executive and PAE and the performance by Executive of Executive’s duties hereunder shall not constitute a breach of, or otherwise contravene, or be prevented, interfered with or hindered by, the terms of any employment agreement or other
agreement or policy to which Executive is a party or otherwise bound. 
 SECTION 6.11. 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 6.12. Set Off. PAE’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 PAE or its affiliates, except as provided in Section 6.14.

 SECTION 6.13. Withholding Taxes. PAE 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. 

  
 14 

 SECTION 6.14. Section 409A. (a) It is intended that the
provisions of this Agreement comply with Section 409A (“Section 409A”) of the Code, 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 PAE 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 PAE or any of its affiliates. 

(c) 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 PAE from time to time) and (ii) PAE 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 PAE (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 Company Plan to the
contrary, in light of the uncertainty with respect to the proper application of Section 409A, PAE reserves the right to make amendments to any Company Plan as PAE 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 PAE 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, Executive shall not be entitled to any payments or benefits payable hereunder as a result of Executive’s termination of
employment with PAE 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. 

  
 15 

 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. (a) 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. 
 (b) 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”.

PAE and its subsidiaries and affiliates and their predecessors, successors and assigns.
