Form Director Restricted Stock Unit Agreement under the 2022 Incentive Award Plan

Capitalized terms not specifically defined in this Restricted Stock Unit Grant Notice (the “Grant Notice”) have the meanings given to them in the 2022 Incentive Award Plan (as amended from time to time, the “Plan”) of Justworks, Inc. (the “Company”).

The Company hereby grants to the participant listed below (“Participant”) the Restricted Stock Units described in this Grant Notice (the “RSUs”), subject to the terms and conditions of the Plan and the Restricted Stock Unit Agreement attached hereto as Exhibit A (the “Agreement”), both of which are incorporated into this Grant Notice by reference. Each RSU is hereby granted in tandem with a corresponding dividend equivalent to the extent a portion of such RSU is vested, as further described in Article II of the Agreement (the “Dividend Equivalents”).

By Participant’s signature below or electronic acceptance or authentication in a form authorized by the Company, Participant agrees to be bound by the terms of this Grant Notice, the Plan and the Agreement. Participant has reviewed the Plan, this Grant Notice and the Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Grant Notice and fully understands all provisions of the Plan, this Grant Notice and the Agreement.

Participant hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Plan, the Grant Notice and the Agreement.

Pursuant to the Grant Notice to which this Agreement is attached, the Company has granted to Participant the number of RSUs set forth in the Grant Notice.

Section 1.1Defined Terms. Capitalized terms not specifically defined herein shall have the meanings specified in the Plan or the Grant Notice. For purposes of this Agreement,

(a)“Cessation Date” shall mean the date of Participant’s Termination of Service (regardless of the reason for such termination).

(b)“Participating Company” shall mean the Company or any of its parents or Subsidiaries.

Section 1.2Incorporation of Terms of Plan. The RSUs and the shares of Common Stock issued to Participant hereunder (“Shares”) are subject to the terms and conditions set forth in this Agreement and the Plan, which is incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan shall control.

(a)In consideration of Participant’s past and/or continued employment with or service to a Participating Company and for other good and valuable consideration, effective as of the grant date set forth in the Grant Notice (the “Grant Date”), the Company has granted to Participant the number of RSUs set forth in the Grant Notice, upon the terms and conditions set forth in the Grant Notice, the Plan and this Agreement, subject to adjustment as provided in Article VIII of the Plan. Each RSU represents the right to receive one Share at the times and subject to the conditions set forth herein. However, unless and until the RSUs have vested, Participant will have no right to the payment of any Shares subject thereto. Prior to the actual delivery of any Shares, the RSUs will represent an unsecured obligation of the Company, payable only from the general assets of the Company.

(b)The Company hereby grants to Participant an Award of Dividend Equivalents with respect to each RSU granted pursuant to the Grant Notice for all ordinary cash dividends that are paid to all or substantially all holders of the outstanding Shares between the Grant Date and the date when the applicable RSU is distributed or paid to Participant or is forfeited or expires. The Dividend Equivalents for each RSU shall be equal to the amount of cash that is paid as a dividend on one Share. All such Dividend Equivalents shall be credited to Participant and be deemed to be reinvested in additional RSUs as of the date of payment of any such dividend based on the Fair Market Value of a Share on such date. Each additional RSU that results from such deemed reinvestment of Dividend Equivalents granted hereunder shall be subject to the same vesting, distribution or payment, adjustment and other provisions that apply to the underlying RSU to which such additional RSU relates.

Section 2.2Vesting of RSUs and Dividend Equivalents.

(a)Subject to Participant’s continued employment with or service to a Participating Company on each applicable vesting date and subject to the terms of this Agreement, the RSUs shall vest in such amounts and at such times as are set forth in the Grant Notice. Each additional RSU that results from deemed reinvestments of Dividend Equivalents pursuant to Section 2.1(b) shall vest whenever the underlying RSU to which such additional RSU relates vests.

(b)In the event Participant incurs a Termination of Service, except as may be otherwise provided by the Administrator or as set forth in a written agreement between Participant and the Company, Participant shall immediately forfeit any and all RSUs and Dividend Equivalents granted under this Agreement that have not vested or do not vest on or prior to the date on which such Termination of Service occurs, and Participant’s rights in any such RSUs and Dividend Equivalents that are not so vested shall lapse and expire.

    (a)    Distribution or Payment of RSUs. Participant’s RSUs shall be distributed in Shares (either in book-entry form or otherwise) within 60 days following the vesting of the applicable RSU pursuant to Section 2.2, and, in any event, no later than March 15th of the calendar year following the year in which such vesting occurred. Notwithstanding the foregoing, the Company may delay a distribution or payment in settlement of RSUs if it reasonably determines that such payment or distribution will violate federal securities laws or any other Applicable Law, provided that such distribution or payment shall be made at the earliest date at which the Company reasonably determines that the making of such distribution or payment will not cause such violation, as required by Treasury Regulation Section 1.409A-2(b)(7)(ii), and provided further that no payment or distribution shall be delayed under this Section 2.3(a) if such delay will result in a violation of Section 409A.

    (b)    All distributions shall be made by the Company in the form of whole Shares, and any fractional share shall be distributed in cash in an amount equal to the value of such fractional share determined based on the Fair Market Value as of the date immediately preceding the date of such distribution.

Section 2.4Conditions to Issuance of Certificates. The Company shall not be required to issue or deliver any certificate or certificates for any Shares or to cause any Shares to be held in book-entry form prior to the fulfillment of all of the following conditions: (a) the admission of the Shares to listing on all stock exchanges on which such Shares are then listed, (b) the completion of any registration or other qualification of the Shares under any state or federal law or under rulings or regulations of the Securities and Exchange Commission or other governmental regulatory body, which the Administrator shall, in its absolute discretion, deem necessary or advisable, (c) the obtaining of any approval or other clearance from any state or federal governmental agency that the Administrator shall, in its absolute discretion, determine to be necessary or advisable, and (d) the receipt of full payment of any applicable withholding tax in accordance with Section 2.5 by the Participating Company with respect to which the applicable withholding obligation arises.

Section 2.5Tax Withholding. Notwithstanding any other provision of this Agreement:

(a)The Participating Companies have the authority to deduct or withhold, or require Participant to remit to the applicable Participating Company, an amount sufficient to satisfy any applicable federal, state, local and foreign taxes required by Applicable Law to be withheld with respect to any taxable event arising pursuant to this Agreement.

(b)Participant is ultimately liable and responsible for all taxes owed in connection with the RSUs, regardless of any action any Participating Company takes with respect to any tax withholding obligations that arise in connection with the RSUs. No Participating Company makes any representation or undertaking regarding the treatment of any tax withholding in connection with the awarding, vesting or settlement of the RSUs or the subsequent sale of Shares. The Participating Companies do not commit and are under no obligation to structure the RSUs to reduce or eliminate

Participant’s tax liability. The Company may refuse to issue any shares of Stock in settlement of the RSUs to Participant until the foregoing tax withholding obligations are satisfied, provided that no payment shall be delayed under this Section 2.5(b) if such delay will result in a violation of Section 409A of the Code.

Section 2.6Rights as Stockholder. Neither Participant nor any Person claiming under or through Participant will have any of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book-entry form) will have been issued and recorded on the records of the Company or its transfer agents or registrars and delivered to Participant (including through electronic delivery to a brokerage account). Except as otherwise provided herein, after such issuance, recordation and delivery, Participant will have all the rights of a stockholder of the Company with respect to such Shares, including, without limitation, the right to receipt of dividends and distributions on such Shares.

Section 2.7[Restrictive Covenants; Forfeiture. The Participant hereby acknowledges and agrees that any restrictive covenants or similar written agreements (the “Restrictive Covenant Agreements”) between such Participant and the Company or any other Participating Company are incorporated herein by reference, and that such agreements, as applicable, remain in full force and effect. In the event the Participant materially breaches the Restrictive Covenant Agreements or any other written covenants between such Participant and any Participating Company, the Participant shall immediately forfeit any and all RSUs and Dividend Equivalents granted under this Agreement (whether or not vested), and Participant’s rights in any such RSUs and Dividend Equivalents shall lapse and expire.]

Section 3.1Administration. The Administrator shall have the power to interpret the Plan, the Grant Notice and this Agreement and to adopt such rules for the administration, interpretation and application of the Plan, the Grant Notice and this Agreement as are consistent therewith and to interpret, amend or revoke any such rules. All actions taken and all interpretations and determinations made by the Administrator will be final and binding upon Participant, the Company and all other interested Persons. To the extent allowable pursuant to Applicable Law (and without limiting Section 10.7 of the Plan), no member of the Committee or the Board will be personally liable for any action, determination or interpretation made with respect to the Plan, the Grant Notice or this Agreement.

Section 3.2RSUs Not Transferable. The RSUs may not be sold, pledged, assigned or transferred in any manner other than by will or the laws of descent and distribution, unless and until the Shares underlying the RSUs have been issued, and all restrictions applicable to such Shares have lapsed. No RSUs or any interest or right therein or part thereof shall be liable for the debts, contracts or engagements of Participant or his or her successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect, except to the extent that such disposition is permitted by the preceding sentence.

Section 3.3Adjustments. The Administrator may accelerate the vesting of all or a portion of the RSUs in such circumstances as it, in its sole discretion, may determine. Participant acknowledges that the RSUs and the Shares subject to the RSUs are subject to adjustment, modification and termination in certain events as provided in this Agreement and the Plan, including Article VIII of the Plan.

By a notice given pursuant to this Section 3.4, either party may hereafter designate a different address for notices to be given to that party.

Section 3.10Limitations Applicable to Section 16 Persons. Notwithstanding any other provision of the Plan or this Agreement, if Participant is subject to Section 16 of the Exchange Act, the Plan, the RSUs (including RSUs that result from the deemed reinvestment of Dividend Equivalents), the Dividend Equivalents, the Grant Notice and this Agreement shall be subject to any additional limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of the Exchange Act) that are requirements for the application of such exemptive rule. To the extent permitted by Applicable Law, this Agreement shall be deemed amended to the extent necessary to conform to such applicable exemptive rule.

Section 3.11Not a Contract of Employment or Engagement.

However, notwithstanding anything in the Plan, the Grant Notice or this Agreement to the contrary, the Administrator may, without a Participant’s consent,

amend this Plan or Awards, adopt policies and procedures, or take any other actions (including amendments, policies and procedures and retroactive actions) as are necessary or appropriate to preserve the intended tax treatment of Awards, including any actions intended to (A) exempt this Plan or any Award from Section 409A, or (B) comply with Section 409A, including regulations, guidance, compliance programs and other interpretive authority that may be issued after an Award’s grant date.

Section 3.14Agreement Severable. In the event that any provision of the Grant Notice or this Agreement is held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of the Grant Notice or this Agreement.

Section 3.15Limitation on Participant’s Rights. Participation in the Plan confers no rights or interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Company as to amounts payable and shall not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets. Participant shall have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the RSUs and Dividend Equivalents.
