Executive Severance Policy

This Executive Severance Policy (the “Policy”) was adopted on September 15, 2020 and amended and restated on December 14, 2021, to be effective as of immediately prior to an initial public offering or direct listing of the Company’s equity securities (“IPO”) until amended or terminated by the Board of Directors of Justworks, Inc. (the “Board”) in accordance with the terms hereof. To the extent an IPO does not occur on or prior to June 30, 2022, the amendment and restatement on December 14, 2021 shall not be effective and the Policy, as in effect immediately prior to such amendment and restatement, shall continue in full force and effect.

Employees of the Company who have the title of Vice President and above who have received a Participation Notice from the Company in substantially the same form as Exhibit A attached hereto and have executed and returned such Participant Notice to the Company (each, a “Participant”).

The Company intends to provide a Participant with one month’s advance notice of a Termination Without Cause. Alternatively, the Company may choose to effect a Termination Without Cause by providing less than one month’s notice, in which case the Company will pay the Participant the base salary that the Participant would have earned during the foregone notice period.

In the event of a Participant’s resignation, the Company requests that the Participant provide the Company with one month’s advance notice.

As a condition to receipt of any severance benefits pursuant this Policy, a Participant must:

•Sign (and not revoke) a general release of all claims in a form provided by the Company by the deadline specified by the Company which will in no event be later than fifty days after a Participant’s employment terminates,

•Continue to comply with the provisions of any Employee Proprietary Information, Inventions and Non-Competition Agreement between the Participant and the Company and any similar agreement containing restrictive covenants in favor of the Company between the Participant and the Company (each, as applicable, a “PIIA”), and

•If requested by the Board, immediately resign as a member of the Board and as a member of the board of directors of any subsidiaries of the Company and, if requested by the Administrator, immediately resign as an officer or other similar position at the Company or any of subsidiaries of the Company.

For avoidance of doubt, no severance benefits will be paid unless the release referred to above becomes effective. In the event a Participant breaches his or her PIIA, the Company’s obligation to provide severance benefits will end and no further severance benefits will be paid or provided.

If a Participant is subject to an Involuntary Termination and the Participant satisfies the conditions to receive severance benefits described above, the Participant shall receive the following severance benefits:

•Severance Payments: Cash severance payments with an aggregate value equal to 50% of the sum of (a) Participant’s annual base salary and (b) target annual cash bonus, at the rate in effect at the time of the Involuntary Termination, payable in six (6) equal monthly installments on the first payroll date of each month.

•Pro-Rated Bonus: A pro rata portion of the Participant’s target bonus for the fiscal year in which the Involuntary Termination occurs based on number of days worked in such fiscal year (including the notice period), payable in a lump sum.

•Stipend: A $10,000 benefits stipend, payable in a lump sum.

•Health Benefits (US only): Reimbursement of the Participant’s COBRA premiums (to the extent the Participant is eligible for and timely elects continued health insurance coverage under COBRA) for a period of 6 months following the month in which the Involuntary Termination occurs.

•Extended Post-Termination Exercise Period: The post-termination exercise period applicable to the Participant’s stock options (to the extent vested and outstanding as of the Participant’s termination date) will be extended so that the Participant shall be able to exercise such stock options until the earlier of (1) the date two years after the Participant’s termination date or (2) the expiration date of the option, subject to earlier termination pursuant to Section 8(b) of the Company’s 2018 Stock Plan, Section 9 of the Company’s 2012 Stock Incentive Plan or Article VIII of the Company’s 2022 Incentive Award Plan, as applicable (and any similar provisions of any successor equity plan thereto). Notwithstanding the foregoing, this benefit will not apply to any stock option outstanding on the effective date of this Policy that is intended to be an “incentive stock option” under the federal tax laws.

•Double Trigger: Unless the Company provides otherwise when an equity award is granted, if an Involuntary Termination occurs within three months prior to, or twenty-four months following, a Change in Control, 100% of the unvested portion of each outstanding equity award that the Participant holds as of the Involuntary Termination will vest and, if applicable, become exercisable.

All cash severance benefits will be paid or commence within sixty days after a Participant’s Involuntary Termination and once they commence, will include any unpaid amounts accrued from the date of the Participant’s Involuntary Termination. If such sixty day period spans calendar years, then payment will in any event be made or commence in the second calendar year.

For avoidance of doubt, if a Participant is subject to an Involuntary Termination that occurs within three months prior to a Change in Control, the portion of the Participant’s then-outstanding and unvested equity awards that is eligible to vest and become exercisable pursuant to the Double Trigger will remain outstanding for three months or through the occurrence of a Change in Control, whichever is sooner, so that any additional benefits due pursuant to the Double Trigger may be provided if a Change in Control occurs within three months after the Participant’s Involuntary Termination, provided that in no event will any of Participant’s stock options remain outstanding beyond the option’s maximum term to expiration. If a Change in Control does not occur within three months after an Involuntary Termination, any unvested portion of the Participant’s equity awards that remained outstanding following Participant’s Involuntary Termination will immediately and automatically be forfeited.

•All payments and benefits pursuant to this Policy are subject to reduction to reflect applicable withholding and payroll taxes and other deductions required by law.

•The Company intends that all payments and benefits provided pursuant to this Policy are exempt from, or comply with, with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) so that none of the payments or benefits will be subject to the additional tax imposed under Code Section 409A, and any ambiguities herein will be interpreted in accordance with such intent.

•For purposes of Code Section 409A, each payment, installment or benefit payable under this Policy is hereby designated as a separate payment.

•If the Company determines that a Participant is a “specified employee” under Code Section 409A(a)(2)(B)(i) at the time of Participant’s Separation, then (i) any severance payments or benefits, to the extent that they are subject to Code Section 409A, will not be paid or otherwise provided until the first business day following (A) expiration of the six-month period measured from the Participant’s Separation or (B) the date of the Participant’s death and (ii) any installments that otherwise would have been paid or provided prior to such date will be paid or provided in a lump sum when the severance payments or benefits commence.

•In the event that any payment or benefit received or to be received by the Participant pursuant to this Policy or otherwise (collectively, the “Payments”) would subject the Participant to any excise tax pursuant to Section 4999 of the Code (the “Excise Tax”) due to the characterization of such Payments as an excess parachute payment under Section 280G of the Code, then, notwithstanding the other provisions of this Policy or otherwise, the amount of such Payments will not exceed the amount which produces the greatest after-tax benefit to the Participant. For purposes of this paragraph, if the Payments must be reduced, then such Payments shall be reduced in such manner (and in such order) as determined by the Company in good faith based on determinations of the 280G Advisor (as defined below), subject to compliance with Section 409A of the Code.

•Upon the occurrence of any event that would give rise to any Payments (an “Event”), the Company shall request a determination to be made in connection with the Event by a nationally recognized independent public accounting firm or other third party advisor with experience in performing calculations regarding the applicability of Section 280G of

the Code and the Excise Tax selected by the Company (the “280G Advisor”) of the amount and type of such Payments which would produce the greatest after-tax benefit to the Participant. For the purposes of such determination, the 280G Advisor may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and the Participant shall furnish to the 280G Advisor such information and documents as the 280G Advisor may reasonably request in order to make its required determination. The Company shall bear all fees and expenses the 280G Advisor may reasonably charge in connection with its services contemplated by this paragraph. In the event that, following the payment of any Payment(s), it is determined that a greater reduction in the Payment(s) than initially determined by the 280G Advisor should have been made to implement the objectives and intent of this paragraph, the excess amount shall be returned immediately by the Participant to the Company (or the applicable payor).

•Any determination related to the Payments, the Excise Tax or any reduction in the Payments as described herein made by the Company in good faith based on the determinations of the 280G Advisor shall be final, binding and conclusive on the applicable Participant and all other persons or entities.

•The Administrator shall have the exclusive discretion and authority to construe and interpret the Policy and to decide any and all questions of fact, interpretation, definition, computation or administration arising in connection with the operation of the Policy, including, but not limited to, the eligibility to participate in the Policy and the amount of benefits paid under the Policy. The rules, interpretations, computations and other actions of the Administrator shall be binding and conclusive on all persons.

•Nothing contained in this Policy shall (a) confer upon any Participant any right to continue in the employ of the Company, (b) constitute any contract or agreement of employment, or (c) interfere in any way with the at-will nature of the Participant’s employment with the Company.

•This Policy is unfunded, and all benefits hereunder shall be paid only from the general assets of the Company.

•“Change in Control” shall mean the consummation of any transaction or series of related transactions (including the acquisition of the Company by another entity and any reorganization, merger, consolidation or share exchange, but excluding the sale of stock by the Company in a bona fide financing transaction) that results in the holders of record of the Company's capital stock immediately prior to the transaction or related transactions holding less than 50% of the voting power of the Company or acquiring company, as applicable, immediately after the transaction or related transactions, or which results in the sale of all or substantially all of the assets of the Company or in the exclusive license of all or substantially all of the intellectual property of the Company.
