 Exhibit 10.7 

APERGY CORPORATION 

EXECUTIVE SEVERANCE PLAN 

Introduction 
 This Apergy Corporation
Executive Severance Plan (the “Plan”) sets forth the policy of Apergy Corporation, a Delaware corporation (“Apergy”), and each of its Subsidiaries (as defined in Article 13) which employs an “Eligible Executive” (as
defined in Article 1) with respect to “Severance Payments” (as defined in Article 5) payable to an Eligible Executive under the Plan. (Apergy and such Subsidiaries are collectively referred to as the “Company”). This Executive
Severance Plan constitutes the plan document and summary plan description for the Plan. 
  

	Article 1.	Who is Eligible for Participation in the Plan 

  

	a.	Eligible Executives. Those executives who (i) are Presidents of a business unit of the Company, Vice Presidents of Apergy, and officers of Apergy senior to Vice Presidents of Apergy, (ii) are (A)
employed in the United States, or (B) a U.S.-based employee temporarily assigned to the non-U.S. payroll of a Subsidiary on an expatriate assignment, and (iii) on the date of a covered termination of
employment, remain in such a position, (“Eligible Executives”), shall be eligible to receive Severance Payments under the Plan. 

  

	b.	Effect of Employment Agreement. You shall not be eligible to participate in the Plan if you are party to a written agreement with the Company that provides for severance payments to you upon, or following, the
termination of your employment. 

  

	c.	Other Plans. If you are eligible to participate in this Plan, you shall not be eligible to participate in, or to receive any severance benefits under, any other severance plan, policy, practice, or arrangement
maintained by the Company. If you become eligible to receive Severance Payments under the Apergy Corporation Senior Executive Change-in-Control Severance Plan, you shall
not be eligible to receive Severance Payments under this Plan. 

  

	Article 2.	How Do You Become Eligible for Severance Payments under the Plan 

 You will be eligible for
Severance Payments if you are an Eligible Executive and your employment is terminated by the Company without “Cause” (as defined in Article 13) (“Termination Without Cause”). 

 

	Article 3.	What Events Make You Ineligible for Severance Payments under the Plan 

 You shall not be entitled
to receive Severance Payments under this Plan if any of the following disqualifying events occur: 
  

	a.	Death or Disability. Your employment terminates due to death or, at the option of the Company, upon your “Disability” (as defined in Article 13); 

	b.	Voluntary Termination. You elect to terminate your employment with the Company or a successor for any reason, including without limitation, retirement. 

 

	c.	Termination for Cause. Your employment with the Company is terminated for Cause (“Termination for Cause”): 

  

	 	•	Your employment may be terminated for Cause by the Company effective upon the giving of written notice to you of such Termination for Cause, or effective upon another date as specified in such notice. 

 

	 	•	If within one (1) year after your Termination Without Cause, the Company determines that your employment could have been Terminated for Cause, your prior termination shall be recharacterized as a Termination for
Cause upon the Company giving written notice to you (or to your estate in the event of your death). You (or your estate) shall have thirty (30) days to provide a written response to the Company. To the extent that the Company does not reverse
its determination after receipt of your response, if any, you (or your estate) shall be obligated promptly to repay any Severance Payments paid to you under the Plan. The Company may take appropriate legal action to seek to recover any Severance
Payments from you or your estate. 

  

	d.	Sale. You work for a division, subdivision, plant, location, or entity which is sold or otherwise transferred to an entity other than Apergy and its Subsidiaries, regardless of whether the new owner offers
continued or comparable employment to you. 

  

	e.	New Employer. You begin working for another employer (whether regular or temporary and whether full-time or part-time) in any capacity, including as a consultant or independent contractor, before your “Date
of Termination” (as defined in Article 13). You are required to immediately notify the Company in writing if you begin another job prior to your Date of Termination. 

 

	Article 4.	What Amounts Other than Severance Payments May be Payable to You 

 Regardless of whether you are
eligible for Severance Payments under the Plan, you may be entitled to receive benefits (other than severance payments) for which you are expressly eligible following your Date of Termination to the extent you are entitled under the terms and
conditions of any other plans, policies, programs and/or arrangements of the Company, including without limitation, continuation health benefits under the federal law known as COBRA, and amounts payable or benefits provided under the Apergy
Corporation 2018 Equity and Cash Incentive Plan and any successor plan, the Apergy Corporation Executive Deferred Compensation Plan, and the Apergy Corporation 401(k) Plan. 
  

	Article 5.	What Severance Payments Are Payable under the Plan 

 If you are eligible to receive Severance
Payments under Article 2 above, and you have not become ineligible for the receipt of such Severance Payments due to a disqualifying event as described in Article 3 above or other provisions of the Plan, you shall be entitled to the following
severance payments (the “Severance Payments”): 

  
 2 

	 	•	Base salary continuation for a twelve (12) month period following your Date of Termination (the “Severance Pay Period”), plus an additional monthly amount equal to the then cost of COBRA health
continuation coverage for yourself and covered family members based on the level of health coverage in effect on your Date of Termination, if any, for the lesser of the Severance Pay Period or the period that you receive COBRA benefits, with such
payments to commence sixty (60) days from your Date of Termination, retroactive to your Date of Termination, provided that you have executed and not revoked a general release of claims against the Company within forty-five (45) days
following the date of termination. 

  

	 	•	If on your Date of Termination you are a “covered employee” (within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”)) who participates in an annual
incentive plan intended to comply with Section 162(m) of the Code, an additional Severance Payment equal to the pro rata portion (based upon the completed calendar months worked in the year in which your Date of Termination occurs) of the
annual incentive bonus paid to you for the year prior to the year in which your Date of Termination occurs, with such amount to be payable when an annual incentive bonus is regularly paid to employees for the year in which your Date of Termination
occurs, which amount may, in the discretion of the Compensation Committee of Apergy’s Board of Directors (“Compensation Committee”), be reduced. 

  

	 	•	If you are not a “covered employee”, an additional Severance Payment equal to a pro rata portion (based upon the completed calendar months worked in the year in which your Date of Termination occurs), of the
target annual incentive bonus payable for the year in which your Date of Termination occurs, with such amount to be payable when an annual incentive bonus is regularly paid to employees for the year in which your Date of Termination occurs, which
amount may, in the discretion of the Compensation Committee (or, if applicable, the manager who approves your bonus) be reduced based upon attainment of the performance criteria applicable to your award for the year of termination.

  

	 	•	If you die before receipt of all Severance Payments to which you are entitled, any payments due to you will be paid to your estate at the time they would have been payable to you. 

 

	 	•	 The Company’s obligations to make Severance Payments to you are conditioned upon your timely execution
(without revocation) of a separation agreement and a general release of all claims related to your employment and the termination of your employment in a form satisfactory to Apergy (the “Separation Agreement and Release”). The Separation
Agreement and Release shall include a confidentiality covenant, a non-disparagement covenant, a covenant for the protection of intellectual property, and a
non-competition and non-solicitation restriction for the duration of the Severance Pay Period, as more fully set forth in such Separation Agreement and Release. Payments
to you shall commence sixty (60) days following your Date of Termination as provided in this Article 5 above 

  
 3 

	 	 
but only if you have executed such Separation Agreement and Release within forty-five (45) days following the Date of Termination and the applicable revocation period has expired. Where the
forty-five (45) day period extends into the next year, payment shall commence in the next taxable year. If you should fail to execute such Separation Agreement and Release within forty-five (45) days following the Date of Termination or
should you later revoke or violate the Separation Agreement and Release, the Company shall not have any obligation to make the payments contemplated under this Plan and you shall refund any Severance Payments made to you. 

 

	Article 6.	Claw-Back Provisions 

 In addition to the right of the Company, under Article 3(c) and Article 5,
to recover amounts paid to you, in the event that you shall (i) breach the non-competition, non-disparagement,
non-solicitation, confidentiality, intellectual property or other covenants or provisions of the Separation Agreement and Release, or (ii) be required by any claw-back policies of the Company, as in
effect from time to time, or by applicable law, to refund payments received from the Company as the result of a restatement of the Company’s financial statements or other events or conduct as may be specified in such policies from time to time
or as may be required by applicable law, you (or your estate) shall be obligated promptly to refund the Severance Payments made to you. The Company may take appropriate legal action to seek to recover any Severance Payments from you or your estate.

  

	Article 7.	Income Taxes  

 Severance Payments are subject to all applicable federal, state, local and non-U.S. tax withholdings. 
  

	Article 8.	Section 409A of the Code  

 Notwithstanding any other provision of the Plan, if any payment,
compensation or other benefit provided to you in connection with your employment termination is determined, in whole or in part, to constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code and you
are a “specified employee” as defined in Code Section 409A(a)(2)(B)(i), no part of such payments shall be paid before the day that is six (6) months plus one (1) day after your Date of Termination (such date, the “New
Payment Date”). The aggregate of any payments that otherwise would have been paid to you during the period between your Date of Termination and the New Payment Date shall be paid to you in a lump sum on such New Payment Date. Thereafter, any
payments that remain outstanding as of the day immediately following the New Payment Date shall be paid without delay over the time period originally scheduled in accordance with the terms of the Plan. If you die during the period between the Date
of Termination and the New Payment Date, the amounts withheld on account of Code Section 409A shall be paid to your estate within ninety (90) days following your death. 

For the avoidance of doubt, up to two (2) times the lesser of: (i) your base salary for the year preceding the year in which your Date of
Termination occurs; and (ii) the maximum amount of compensation that may be taken into account under a qualified plan pursuant to Code Section 401(a)(17) for the year in which your Date of Termination occurs, shall be paid in accordance with
the schedule set forth in Article 5, without regard to such six (6) month delay. 

  
 4 

 The provisions of the Plan are intended to be exempt from, or to comply with, the requirements of Code
Section 409A, including without limitation, with the separation pay exemption and short-term deferral exemption of Code Section 409A. The Plan shall in all respects be administered in accordance with Code Section 409A and shall be
interpreted in a manner to conform to the requirements of Code Section 409A. Notwithstanding anything in the Plan to the contrary, distributions may only be made under the Plan upon an event and in a manner permitted by Code Section 409A
or an applicable exemption. 
 All payments to be made upon a termination of employment under the Plan may only be made upon a “separation from
service” under Code Section 409A. 
 For purposes of Code Section 409A, the right to a series of installment payments under the Plan shall be
treated as a right to a series of separate payments. In no event may you, directly or indirectly, designate the calendar year of a payment. 
  

	Article 9.	Administration of Plan  

 The “Plan Administrator” (as defined in Article 13) shall have
the exclusive right, power, and authority, in its sole and absolute discretion, to administer, apply, and interpret the Plan and to decide all matters arising in connection with the operation or administration of the Plan to the extent not retained
by Apergy as set forth herein. Without limiting the generality of the foregoing, the Plan Administrator shall have the sole and absolute discretionary authority to: 
  

	•	Make determinations as to whether an employee is, or is not, an Eligible Executive; 

  

	•	Take all actions and make all decisions with respect to the eligibility for, and the amount of, Severance Payments payable under the Plan; 

 

	•	Formulate, interpret and apply rules, regulations, and policies necessary to administer the Plan in accordance with its terms; 

  

	•	Decide questions, including legal or factual questions, with regard to any matter related to the Plan; 

  

	•	Construe and interpret the terms and provisions of the Plan and all documents which relate to the Plan and decide any and all matters arising thereunder including the right to remedy possible ambiguities,
inconsistencies or omissions; 

  

	•	Investigate and make such factual or other determinations as shall be necessary or advisable for the resolution of appeals of adverse determinations under the Plan; and 

 

	•	Process, and approve or deny, claims for Severance Payments under the Plan and any appeals. 

  
 5 

 All determinations made by the Plan Administrator as to any question involving its respective responsibilities,
powers and duties under the Plan shall be final and binding on all parties, to the maximum extent permitted by law. All determinations by Apergy referred to in the Plan shall be made by Apergy in its capacity as an employer and settlor of the Plan.

  

	Article 10.	Modification or Termination of Plan  

 Apergy reserves the right, in its sole and absolute
discretion, to amend, modify, or terminate the Plan, in whole or in part, including any or all of the provisions of the Plan, for any reason, at any time, by action of the Compensation Committee. This Plan does not give an Eligible Executive any
vested right to Severance Payments. If the Plan is amended or terminated, your rights to receive Severance Payments may be eliminated. No individual may become entitled to benefits or other rights under the Plan after the Plan is terminated. 

 

	Article 11.	Claims and Appeal Procedures  

 The Plan Administrator shall make a determination in connection
with the termination of employment of an Eligible Executive as to whether a Severance Payment under the Plan is payable to such Eligible Executive and the amount thereof, taking into consideration any determination made by Apergy as to the
circumstances regarding the termination, the potential applicability of a disqualifying event, or the Plan Administrator’s decision as to whether an employee is an Eligible Executive under the Plan. The Plan Administrator shall advise any
Eligible Executive it determines is entitled to Severance Payments under the Plan as to the amount of Severance Payments payable under the Plan. The Plan Administrator may delegate any or all of its responsibilities under this section. 

 

	a.	Claim Procedures 

 Each Eligible Executive or his or her authorized representative (each, the
“Claimant”) claiming Severance Payments under the Plan who has not been advised by the Plan Administrator as to his or her eligibility for Severance Payments, disagrees with a determination that he or she is not eligible for Severance
Payments, disagrees with the amount of any Severance Payments awarded under the Plan, or disagrees with a decision to require him or her to repay an amount under the Plan, is eligible to file a written claim with the Plan Administrator. 

Within ninety (90) days after receiving the claim, the Plan Administrator will decide whether or not to approve the claim. The ninety (90)-day period may be extended by the Plan Administrator up to an additional ninety (90)-day period if special circumstances require an extension of time to consider the
claim. If the Plan Administrator extends the ninety (90)-day period, the Claimant will be notified in writing before the expiration of the initial ninety (90)-day period
as to the length of the extension and the special circumstances that necessitate the extension. 
 If the claim is denied, the Plan Administrator shall set
forth in writing (which notice may be electronic) the reasons for the denial; the relevant provisions of the Plan on which the decision is made; a description of the Plan’s claim appeal procedures; and, if additional material or information is
necessary to perfect the claim, an explanation of why such material or information is necessary. The notice will also include a statement regarding the procedures for the Claimant to file a request for review of the claim denial as set forth in the
“Appeal Procedures” sub-section 

  
 6 

 
below and the Claimant’s right to bring a civil action under Section 502(a) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) following a claim
denial on appeal. 
  

	b.	Appeal Procedures 

 If a claim has been denied by the Plan Administrator and the Claimant wishes further
consideration and review of his or her claim, he or she must file an appeal of the denial of the claim to the Plan Administrator no later than sixty (60) days after the receipt of the written notification of the Plan Administrator’s
denial. In connection with his or her appeal, the Claimant may request the opportunity to review relevant documents prior to submission of a written statement, submit documents, records and comments in writing, and receive, upon request and free of
charge, reasonable access to and copies of all documents, records and other information relevant to the Claimant’s claim for Severance Payments under the Plan. The review of the appeal by the Plan Administrator will take into account all
comments, documents, records and other information submitted by the Claimant relating to the claim, without regard to whether such information was submitted or considered in the initial review of the claim. 

The Plan Administrator will notify the Claimant in writing (which notice may be electronic) of the Plan Administrator’s decision with respect to its
review of the appeal within sixty (60) days following the receipt of the request for a review of the claim. Due to special circumstances, the Plan Administrator may extend the time to reach a decision with respect to the appeal of the claim
denial, in which case the Plan Administrator will notify the Claimant in writing before the expiration of the initial 60-day period as to the length of the extension and the special circumstances that
necessitate such extension and render a decision as soon as possible, but not later than one hundred twenty (120) days following the receipt of the Claimant’s request for appeal. 

If the appeal is denied, the Plan Administrator will set forth in writing (which notice may be electronic) the specific reasons for the denial and references
to the relevant Plan provisions on which the determination of the denial is based. The notice will also include a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all
documents, records and other information relevant to the claim, and a statement of the Claimant’s right to bring an action under Section 502(a) of ERISA. 
  

	c.	Exhaustion of Remedies under the Plan 

 A Claimant wishing to seek judicial review of an adverse benefit
determination under the Plan, whether in whole or in part, must file any suit or legal action, including, without limitation, a civil action under Section 502(a) of ERISA, within one (1) year following the date the final decision on the
adverse benefit determination on review is issued or should have been issued or lose any rights to bring such an action. If any such judicial proceeding is undertaken, the evidence presented shall be strictly limited to the evidence timely presented
to the Plan Administrator. A Claimant may bring an action under ERISA only after he or she has exhausted the Plan’s claims and appeal procedures. 

  
 7 

	Article 12.	Miscellaneous Provisions  

  

	•	The records of the Company with respect to employment history, compensation, absences, illnesses, and all other relevant matters shall be conclusive for all purposes of this Plan. 

 

	•	The respective terms and provisions of the Plan shall be construed, whenever possible, to be in conformity with the requirements of ERISA, or any subsequent laws or amendments thereto. To the extent not to conflict with
the preceding sentence, the construction and administration of the Plan shall be in accordance with the laws of the state of Texas applicable to contracts made and to be performed within the state of Texas (without reference to its conflicts of law
provisions). 

  

	•	Nothing contained in this Plan shall be held or construed to create any liability upon the Company to retain any employee in its service or to change the
employee-at-will status of any employee. All employees shall remain subject to the same terms and conditions of employment and discharge or discipline to the same extent
as if the Plan had not been put into effect. An employee’s failure to qualify for, or receive, a Severance Payment under the Plan shall not establish any right to (i) continuation or reinstatement, or (ii) any benefits in lieu of
Severance Payments. 

  

	•	The Company has the right to cancel a proposed termination of employment or reschedule a termination date at any time before your employment terminates. You will not become eligible for Severance Payments if your
termination date is cancelled or if you voluntarily terminate employment before the termination date specified or rescheduled by the Company. 

  

	•	Severance Payments under this Plan are not intended to duplicate such (i) payments and benefits as may be provided to you under state, local, federal or non-US plant shut
down, mass layoff or similar laws, such as the WARN Act or (ii) payments in the nature of severance or separation pay, termination allowances or indemnities, and/or pay or benefits in lieu of notice, pay and/or benefits for service during any
notice period, or any similar type of payment or benefit under any non-US plan, program or policy, under any non-US contract or agreement or between a union, works
council or other collective bargaining entity or employee representative and the Company, or under applicable non-US laws or regulations. Should payments or benefits under such laws or other arrangements
become payable to you, payments under this Plan will be offset or reduced (but not below zero) by all payments and benefits to which you are entitled under such other laws or arrangements, or alternatively, Severance Payments previously paid under
this Plan will be treated as having been paid to satisfy such other benefit obligations to the extent permitted by applicable law. In either case, the Plan Administrator, in its sole discretion, will determine how to apply this provision and may
override other provisions in this Plan in doing so. 

  

	•	At all times, payments under the Plan shall be made from the general assets of the Company. 

  
 8 

	•	Should any provisions of the Plan be deemed or held to be unlawful or invalid for any reason, the balance of the Plan shall remain in effect, unless it is amended or terminated as provided in the Plan.

  

	•	Except as required by law, the Severance Payments will not be subject to alienation, transfer, assignment, garnishment, execution or levy of any kind, and any attempt to cause such payments to be so subjected will not
be recognized. 

  

	•	If any overpayment is made under the Plan for any reason, the Plan Administrator will have the right to recover the overpayment. 

  

	•	The Company shall cause this Plan to be assumed by a successor of the Company, whether such succession occurs by merger, asset sale or otherwise. 

 

	•	Any notice or other written communication required or permitted pursuant to the terms of the Plan shall have been duly given (i) immediately when delivered by hand, (ii) three days after being mailed by United
States Mail, first class, postage prepaid (or such local equivalent thereof), addressed to the intended recipient at his, her or its last known address, (iii) on the next business day after deposit with a courier or overnight delivery service
post paid for next-day delivery and addressed in accordance with the last known address, or (iv) immediately upon delivery by facsimile or email to the telephone number or email address provided by a
party for the receipt of notice.

 SUMMARY OF ERISA RIGHTS 

Your Rights Under ERISA 
 The Department of Labor has
issued regulations that require the Company to provide you with a statement of your rights under ERISA with respect to this Plan. The following statement was designated by the Department of Labor to satisfy this requirement and is presented
accordingly. 
 As a participant in the Plan, you are entitled to certain rights and protections under ERISA. ERISA provides that all Plan participants are
entitled to: 
 Receive Information About Your Plan and Benefits 

1. Examine, without charge, all Plan documents and copies of all documents filed by Apergy with the Department of Labor and available at the Public Disclosure
Room of the Employee Benefits Security Administration. This includes annual reports and Plan descriptions. All such documents are available for review from the Apergy Human Resources Department. 

2. Obtain, upon written request to the Plan Administrator, copies of documents governing the operation of the Plan, including copies of the latest annual
report (Form 5500 Series) and any updated summary plan description. The Plan Administrator may charge you a reasonable fee for the copies. 
 3. Receive a
summary of the Plan’s annual financial report. Once each year, the Plan Administrator will send you a Summary Annual Report of the Plan’s financial activities at no charge. 

Prudent Action by Fiduciaries 
 In addition to
creating rights for Plan participants, ERISA imposes duties upon the people who are responsible for the operation of the Plan. The people who operate your Plan, called fiduciaries of the Plan, have a duty to do so prudently and in the interest of
you and other Plan participants and beneficiaries. 
 No one, including your employer or any other person, may fire you or otherwise discriminate against
you in any way to prevent you from obtaining a benefit under the Plan or exercising your rights under ERISA. 
 Enforcing Your Rights 

If your claim for Severance Payments is denied or ignored in whole or in part, you have a right to receive a written explanation of the reason for the denial,
to obtain copies of documents related to the decision without charge, and to appeal any denial, all within certain time schedules. You have the right to have your claim reviewed and reconsidered as explained in the “Claims and Appeal
Procedures” section. 

  
 11 

 Under ERISA, there are steps you can take to enforce the above rights. For instance, if you request materials
from the Plan and do not receive them within thirty (30) days, you may file suit in a federal court. In such a case, the court may require the Plan Administrator to provide the materials and pay you up to $110 a day until you receive the
materials, unless the materials were not sent because of reasons beyond the control of the Plan Administrator. If you have a claim for Severance Payments which is denied or ignored, in whole or in part, you may file suit in a state or federal court
after you have exhausted the Plan’s claims and appeal procedures as described in the section “Claims and Appeal Procedures” hereof. If it should happen that Plan fiduciaries misuse the Plan’s money, or if you are discriminated
against for asserting your rights, you may seek assistance from the Department of Labor, or you may file suit in a federal court. 
 The court will decide
who should pay court costs and legal fees. If you are successful, the court may order the person you sued to pay these costs and fees. If you lose, the court may order you to pay these costs and fees, for example, if it finds your claim is
frivolous. 
 Assistance with Your Questions 
 If you
have any questions about the Plan, you should contact the Plan Administrator through the Apergy Human Resources Department. They will be glad to help you. If you have any questions about this statement or about your rights under ERISA, or if you
need assistance in obtaining documents from the Plan Administrator, you should contact the nearest Area Office of the Employee Benefits Security Administration, Department of Labor, listed in your telephone directory, or you may contact:

other unusual, nonrecurring items which are separately identified and quantified in the Company’s audited financial statements, so long as such accounting change is required or such transaction or nonrecurring item occurs after the goals for
the fiscal year are established, and such adjustments are stated at the time that the performance goals are determined. The Committee may also adjust, upward or downward, as applicable, the Performance Targets to reflect any other extraordinary item

established. 
 (c) Nothing contained in the Plan or any agreement related hereto shall affect or be construed as affecting the terms of the

the Company or otherwise as determined by the Company in its sole discretion.

 (f) It is intended that the Awards granted under the Plan shall be exempt from, or in compliance
with, Section 409A of the Code. In the event any of the Awards issued under the Plan are subject to Section 409A of the Code, it is intended that no payment or entitlement pursuant to this Plan will give rise to any adverse tax
consequences to a Participant under Section 409A of the Code. The Plan shall be interpreted to that end and, consistent with that objective and notwithstanding any provision herein to the contrary, the Company may unilaterally take any action
it deems necessary or desirable to amend any provision herein to avoid the application of, or excise tax under, Section 409A of the Code. Neither the Company nor its current or former employees, officers, directors, representatives or agents
shall have any liability to any current or former Participant with respect to any accelerated taxation, additional taxes, penalties, or interest for which any current or former Participant may become liable in the event that any amounts payable
under the Plan are determined to violate Section 409A. 
 (g) Notwithstanding anything herein to the contrary, to the extent required by
Section 409A of the Code and Treasury regulations, upon a termination of employment (other than as a result of death) of a person determined by the Board of Directors of the Company (or a committee of the Board of Directors as such body shall
delegate) to be a “specified employee” (within the meaning of Section 409A of the Code), distributions determined, in whole or in part, to constitute “nonqualified deferred compensation” within the meaning of
Section 409A of the Code shall be delayed until six months after such termination of employment if such termination constitutes a “separation from service” (within the meaning of Section 409A(a)(2)(A)(i) of the Code and the
Treasury regulations issued thereunder) and such distribution shall be made at the beginning of the seventh month following the date of the specified employee’s termination of employment.
