Executive acknowledges that the Company is relying upon the truthfulness and accuracy of such representations in employing Executive.

Any and all disputes in connection with this Undertaking shall be submitted to the exclusive jurisdiction of the competent courts or tribunals, as relevant, located in the city of Tel-Aviv-Jaffa, Israel.

4.5If any provision of this Undertaking is determined by any court of competent jurisdiction to be invalid, illegal or unenforceable in any respect, such provision will be enforced to the maximum extent possible given the intent of the parties hereto. If such clause or provision cannot be so enforced, such provision shall be stricken from this Undertaking only with respect to such jurisdiction in which such clause or provision cannot be enforced, and the remainder of this Undertaking shall be enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not enforceable) never been contained in this Undertaking. In addition, if any particular provision contained in this Undertaking shall for any reason be held to be excessively broad as to duration, geographical scope, activity or subject, it shall be construed by limiting and reducing the scope of such provision so that the provision is enforceable to the fullest extent compatible with applicable law.

4.6The provisions of this Undertaking shall continue and remain in full force and effect following the termination or expiration of the employment relationship between the Company and Executive, for whatever reason. This Undertaking shall not serve in any manner so as to derogate from any of Executive’s obligations and liabilities under any applicable law.

Notwithstanding anything to the contrary in this Undertaking, the obligations under this Undertaking are supplemental to and do not derogate from any obligations that the Executive may have, under law or contract, in any other capacity towards the Company. No amendment, waiver or modification of any obligation under this Undertaking will be enforceable unless set forth in a writing signed by the Company. No delay or failure to require performance of any provision of this Undertaking shall constitute a waiver of that provision as to that or any other instance. No waiver granted under this Undertaking as to any one provision herein shall constitute a subsequent waiver of such provision or of any other provision herein, nor shall it constitute the waiver of any performance other than the actual performance specifically waived.

4.9This Undertaking, the rights of the Company hereunder, and the obligations of Executive hereunder, will be binding upon and inure to the benefit of their respective successors, assigns, heirs, executors, administrators and legal representatives. The Company may assign any of its rights under this Undertaking. Executive may not assign, whether voluntarily or by operation of law, any of its obligations under this Undertaking, except with the prior written consent of the Company.

IN WITNESS WHEREOF, the undersigned, has executed this Undertaking as of the date first mentioned above.

Re: Welcome Offer Letter ("Offer")

Dear Tomer,

On behalf of Unity, I am delighted to welcome you to the Unity group as President, Grow of ironSource Ltd. (the “Company”). As discussed, your current employment agreement with the Company dated June 28, 2021 (hereinafter the "Employment Agreement") shall continue to apply to your employment with the Company as of the Effective Date (as defined below), subject to the terms detailed herein.

If you accept this offer, by signing the Confirmation Section below, it will take effect on (and be conditional upon) the closing of the transaction contemplated in that Agreement and Plan of Merger dated July 13, 2022 by and among the Company and Unity Software Inc. and other parties thereto (the “Effective Date”). To the extent the closing of the merger does not occur, for any reason, this agreement will become null and void and your employment will continue to be governed by your current employment agreement with the Company.

Terms to be effective as of the Effective Date:

1.Title/Position- You shall be engaged in the position of President, Grow and shall report to the Chief Executive Officer.

2.Compensation - The parties have agreed to leave the Executive’s current Salary and Bonus structure in place through the end of 2023.

3.Equity – Subject to applicable law, any future annual equity grants shall be subject to, and be made in accordance with, Unity's Annual executive compensation market review.

For the avoidance of any doubt, Section 12 of Appendix A of the Employment Agreement is canceled.

4.“Double Trigger Event” - The definition of “Double Trigger Event” as listed in Section 3 of Appendix A, shall be replaced with the following definition:

“Dismissal by the Company without Cause or resignation by the Executive for Good Reason within 36 months after a Change in Control.”

5."Good Reason" - The definition of "Good Reason" included in Section 3 of Appendix A of the Employment Agreement shall be amended as follows: the words “reporting obligations” shall be deleted from sub-section (c). For the avoidance of any doubt, any changes agreed upon in this offer, including, but not limited to, a reduction of Salary to the extent agreed to by Executive in accordance with the mechanism set forth in Section 2 above, do not constitute “Good Reason” for any matter or purpose.

6."Cause"- Section 3 of the Employment Agreement shall be amended to include the following new sub-section (g):

"(g) any material breach of the Unity Code of Conduct which, to the extent such breach is curable, has not been cured by the Executive within fifteen (15) days after receipt of notice thereof from the Company".

A copy of Unity’s Code of Conduct can be found via our Investor Relations website and has also been attached to this Agreement.

(i) if provided prior to February 1, 2023 (the "Initial Term") - the Notice Period shall be 12 (twelve) months; (ii) if provided after the lapse of the Initial Term, including a case of dismissal in connection with a Double Trigger Event, the Notice Period shall be 6 (six) months.

8.Policies - Following the Effective Date, Unity policies may apply to your employment and any existing Company policy may change as part of the integration into the Unity group of companies.

9.D&O insurance and indemnification. - The Employee will be covered by Unity’s D&O insurance policy to the extent that their role qualifies them as an insured person under the policy. Those employees who become members of Unity’s Board of Directors, Section 16 Officers of Unity, or Directors and Officers of subsidiaries will also be provided with an indemnification agreement at a later date.

10.Authorities - All authorities that under the Employment Agreement are to be determined by the Board of Directors or Compensation Committee of the Company shall now be managed in accordance with Unity’s standard practices and subject to the approval of the Board of Directors or Compensation Committee of Unity Software Inc.

Other than the abovementioned, all terms of your Employment Agreement shall remain unchanged and shall continue to apply to the employment relationship between you and the Company. In case of any contradiction between this offer and your Employment Agreement, this offer will prevail.

Please sign the Confirmation Section below and return the executed copy to the undersigned by no later than February 28, 2023.

This offer, once executed by you, shall be deemed due notification of change of terms in accordance with the provisions of the Notice to Employee and Job Candidate Law (Employment Conditions and Candidate Screening and Selection) 5762-2002, and the regulations thereunder.
