Whereas, the Executive has been continuously employed by the Company since July 17, 2011 (the "Original Commencement Date"), and whereas, Executive and the Company previously entered into that certain (restated) Employment Agreement, dated March 8, 2017, as amended on November, 2018 (which shall be hereafter together referred to as the “Previous Employment Agreement”); and

Whereas, the parties hereto now wish to amend and restate the Previous Employment Agreement in its entirety, commencing on June 28, 2021 (the "Effective Date");

Now, therefore, the Executive and the Company agree that this Agreement shall amend and restate the Previous Employment Agreement in its entirety, such that from the Effective Date onwards, Executive’s employment shall be in accordance with the terms and conditions set forth herein.

1.The Company shall continue to employ Executive for an indefinite period and Executive has agreed to become so employed, on the terms and conditions set forth herein. The commencement date of the employment, Executive’s position, the reporting duties and other work-related terms, including salary, entitlements and fringe benefits, are specified in Appendix A attached hereto.

Executive undertakes to devote Executive’s full time, attention, skill, and effort exclusively to the performance of Executive’s duties and undertakes not to engage, whether as an employee or otherwise, in any business, commercial or professional activities, whether or not for compensation, during Executive’s employment, without the prior written consent of the Company; provided, however, that, the foregoing limitations shall not include ownership of equity or other investments in any entity (whether public or private) or person as long as: (a) the business of such entity does not, actually or potentially, compete with the business of the Company as then conducted or proposed to be conducted; (b) such entity is not involved in any business or other relationship with the Company; (c) such entity does not have any actual or potential conflict of interest with the Company; and (d) the Executive has no active role in such entity, whether as an employee, consultant or otherwise (other than as permitted in this Section). Notwithstanding the foregoing, the Executive shall be entitled to engage as a non-executive director: (1) with each of the entities set forth under Appendix A-1 attached hereto, and (2) with additional entities subject to the prior approval of the Board of Directors of the Company (or a committee of the Board of Directors designated for such purpose) for such engagement; in each case provided that (i) the Executive does not sign an NDA with that company that may contradict his undertakings set forth under Appendix B attached hereto; (ii) such engagement does not and will not conflict with or derogate from any obligation or undertaking of the Executive hereunder; and (iii) such company does not have any actual or potential conflict of interest with the Company, it being clarified that, in the event that a conflict arises, the Executive shall suspend or terminate his engagement with such company.

The Executive shall be entitled to engage with non-profit organizations, provided his undertakings set forth hereunder are not derogated from.

Nothing contained under this Section 1 shall derogate from Executive’s undertakings in Appendix B attached hereto.

2.This Agreement may be terminated by either party at any time by giving the other party hereto prior written notice of such termination, as specified in Appendix A (the “Notice Period”). Upon termination for any reason other than for Cause, Executive shall be entitled to payment of the Salary and all of the ancillary benefits including continued vesting of his options, restricted share units or other share-based awards, as applicable, for the entire Notice Period. For the removal of doubt, it is clarified that upon any kind of termination of the Executive's employment, other than dismissal by the Company for Cause (as defined below), the Executive shall have the right to remain employed throughout the entire Notice Period, and the Company shall not, whether by way of immediate termination or by way of shortening the Notice Period, cease his employment during the Notice Period, unless otherwise requested in writing by the Executive in the event of termination by the Company. In such event (i.e., upon the Executive's explicit request to shorten his Notice Period and cease his employment during the Notice Period), the Company shall provide the Executive with a payment in lieu of notice, which payment shall comprise of the Salary, and all of the ancillary social benefits and other entitlements, for the remainder of the Notice Period, as if the Executive were to continue to be employed by the Company for the duration thereof.

3.Notwithstanding anything to the contrary in Section 2 above, the Company may terminate the Executive’s employment for Cause. In any event of termination for Cause, the employment under this Agreement shall forthwith terminate and thereafter the Company shall not have any further liability or obligation towards Executive, including with respect to Notice Period. The term “Cause” means any of the following: (a) conviction or indictment of any felony involving moral turpitude whether or not affecting the Company; (b) an act of theft, embezzlement, misappropriation of funds, or fraud; (c) a breach of any non-compete, non-solicitation or similar or comparable obligations of Executive towards the Company or its affiliates which, to the extent such breach is curable, has not been cured by Executive within fifteen (15) days after receipt of written notice thereof from such company; (d) any breach of Executive’s obligations to the Company or its affiliates concerning confidentiality and unauthorized use or disclosure pursuant to any contract or applicable law, except for actions which the Executive proves were performed in good faith and with reasonable basis to believe that such actions will not prejudice the interests of any such company, and based on a reasonable belief that he was not in breach of any such obligations; (e) any material breach of this Agreement which, to the extent such breach is curable, has not been cured by Executive within fifteen (15) days after receipt of notice thereof from the Company; and (f) any other act or omission that would allow termination of the Executive’s employment without severance pay under Sections 16 and 17 of the Severance Pay Law 5713 – 1963.

4.Executive shall have no lien on any of the Company’s assets, equipment or any other material in Executive’s possession, including: car, computer, content of email box, cellular phone and Confidential Information as defined in Appendix B (hereinafter the “Company’s Equipment”). Executive shall return to the Company all Company’s Equipment no later than the day of termination of employer-employee relationship, prior to any unpaid leave or within 7 days following Company’s demand.

5.This Agreement is a personal employment agreement. Nothing herein shall derogate from any right Executive may have, if at all, in accordance with any law, expansion order, collective bargaining agreement, employment agreement or any other agreement with respect to the terms of Executive’s employment, if relevant, which cannot be stipulated against.

6.It is agreed that the Executive’s position is a management one and/or which requires a special degree of personal trust, as defined in the Working Hours and Rest Law, 1951 (the “Working Hours and Rest Law”). Therefore, Executive shall not be granted any other compensation or payment other than expressly specified in Appendix A. Executive undertakes not to claim that the Working Hours and Rest Law applies to Executive’s employment with the Company. Executive acknowledges the legitimacy of the Company’s requirement to work “overtime” or during “weekly rest-hours” without being entitled to “overtime compensation” or “weekly rest-hour compensation” (as these terms are defined in the Working Hours and Rest Law), and Executive undertakes to reasonably comply with such requirements of the Company. Executive acknowledges that the compensation to which Executive is entitled pursuant to this Agreement constitutes adequate compensation for Executive’s work during “overtime” or “weekly rest-hours”.

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

4.4This Undertaking is governed by and construed in accordance with the laws of the State of Israel, without giving effect to its laws pertaining to conflict of laws. 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.
