The Accrued Obligations shall be paid in accordance with the Company’s regular payroll practices.

b.COBRA. In accordance with Section 6(a) of the Employment Agreement, if the Executive elects to continue health plan coverage in accordance with the requirements of applicable law (e.g., COBRA coverage), at the applicable monthly cost charged for such coverage, the Company may require the Executive to complete and file any election forms that are generally required of other employees to obtain COBRA coverage; and the Executive’s COBRA coverage may be terminable in accordance with applicable law.

iii.15.0 times the difference of (A) the Monthly COBRA Continuation Coverage Rate (as defined in the Employment Agreement) determined as of the Separation Date for the Executive’s applicable health and welfare plan coverages as in effect on such date, less (B) the monthly cost to Executive that is being charged for such coverage as of the Separation Date.

d.Accelerated Vesting and Other Adjustments to Retained Options.

i.Notwithstanding the vesting, forfeiture or other provisions of the Plan or the Option Agreement, (a) the Parent shall, as of the later of the Separation Date and Effective Date (as defined below), immediately vest the Bridge Option (as

defined in the Option Agreement) with respect to a total of 29,167 ordinary shares of the Parent (the “Retained Bridge Option”); and (b) up to 20% of the 5-Year Option (as defined in the Option Agreement) (i.e., up to 200,000 ordinary shares of the Parent covered by the 5-Year Option) shall remain eligible to become vested based on actual performance for fiscal year 2022, as calculated in accordance with the terms of the Option Agreement; provided, however, that the amount vested, if any, for fiscal year 2022 shall not be eligible for any of the adjustments set forth in Sections 4(a)(Y) or 4(a)(Z) of the Option Agreement (the “Retained 5-Year Option”, and together with the Retained Bridge Option, the “Retained Options”). For the avoidance of doubt, the portion of the Retained 5-Year Option that becomes vested, if any, shall be considered final following the verification by the Committee (as defined in the Option Agreement) of the AOP (as defined in the Option Agreement) for fiscal year 2022, and if such AOP is less than the maximum AOP target, the amount vested shall not be eligible to any upward adjustments for future performance and the unvested portion of the Retained 5-Year Option shall immediately be deemed forfeited by the Executive and cancelled by the Company. The remainder of the Option shall be immediately forfeited in accordance with their terms.

ii.In addition, and notwithstanding any other provision of the Plan or the Option Agreement, (a) the Parent shall and hereby does permit the vested Retained Options to be exercised at any time during the 36-month period following the Separation Date (but not thereafter) by the Executive or his guardian or legal representative (or by his estate or the person who acquires the Retained Options by will or the laws of descent and distribution or otherwise by reason of the Executive’s death if he dies during such period); and (b) the Executive shall have no dividend equivalent rights of any kind with respect to the Retained Options.

iii.The Executive acknowledges and agrees that the Executive has no rights in any employment-related equity or equity-related interests in the Parent or its Affiliates other than the Executive’s rights in (i) the Retained Options in accordance with the terms of the Plan, the Option Agreement and this Agreement and (ii) the ordinary shares or preferred shares of Parent that are held directly or indirectly by Executive as of the date hereof. If Parent declares a dividend on its ordinary shares or preferred shares and Executive holds such shares on the applicable record date, Parent shall pay or cause to be paid such dividend to Executive in a manner reasonably consistent with the other holders of ordinary shares or preferred shares.

4.Return of Property. By the Separation Date, the Employee must return all property of the Parent or any of its Affiliates, including identification cards or badges, access codes or devices, keys, laptops, computers, telephones, mobile phones, hand-held electronic devices, credit cards, electronically stored documents or files, physical files, and any other property of the Parent or its Affiliates in the Executive’s possession. Executive further acknowledges and agrees that Executive no longer has access to and does not claim ownership of any of the cloud storage or social media accounts of the Parent or its Affiliates.

e.Executive hereby waives all rights to sue or obtain equitable, remedial or punitive relief from any or all Released Parties of any kind whatsoever in respect of any Claim, including, without limitation, reinstatement, back pay, front pay, and any form of injunctive relief.

Executive acknowledges and agrees that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Agreement. Executive further agrees that in the event Executive should bring a Claim seeking damages against the Company, or in the event Executive should seek to recover against the Company in any Claim brought by a governmental agency on Executive’s behalf, this General Release shall serve as a complete defense to such Claims to the maximum extent permitted by law.
