Law 28.1. Your contract of employment with the Company (of which this statement forms part) shall be governed by and construed in all respects in accordance with the laws of the Netherlands. You and the Company each irrevocably submit to the non- exclusive jurisdiction of the Dutch Courts. 29. 30% Ruling. 29.1. If (and insofar as) you are entitled to tax-free reimbursement for extraterritorial costs (30% ruling), your income in this employment contract will be reduced so that, in accordance with the 1965 Wage Tax Act, (article 10ea and further), 100/70 of the newly agreed income shall be equal to the originally agreed income. 29.2. In the event that and insofar as Section 29.1 applies (the 30% ruling), the you will be reimbursed for extraterritorial costs by the Company equal to a maximum of 30/70 of the thus agreed new income under this employment contract. You and the Company acknowledge that application of the ruling to reimburse extraterritorial costs (30%-ruling), may not result in an annual taxable salary below the minimum norm as set out in article 10eb of the Wage Tax (Implementation) Decree 1965 and that the reimbursement of extraterritorial costs can also be lower than 30/70 of the agreed salary. You further acknowledge (and are aware of the fact) that, in accordance with prevailing Dutch tax laws, the adjustment of agreed allowances in accordance with Section 29.1 may affect all allowances and payments related to the salary, such as pensions and social security benefits. 29.3. The 30% ruling, if applicable, will be calculated and applied on receipt of the decision of the Tax Authorities. If application of the ruling is approved in the same Dutch tax year as that in which the employment commenced, the salary and allowance will be re-calculated and applied retroactively from the start of said tax year in which case the deficit suffered by you due to the deduction of taxes and/or social security contributions will be reimbursed. If approval is given after the end of the Dutch tax year in which the employment commenced, the allowance will be recalculated from the start of the calendar year in which it was approved and the above applies mutatis mutandis for that year. 29.4. If at any time it appears that you have received an annual taxable salary below the salary standard in accordance with Article 10eb of the Wage Tax Implementation Decree 1965, which standard is set per calendar year, the 30% ruling will lapse retroactively in the calendar year where the deficit was determined. 29.5. Out of courtesy the Company may pay an advance on the future 30% allowance, awaiting the decision from the Tax Authorities. 29.6. If the Company has wrongly calculated the net wage on the basis of the 30%-ruling and/or has paid an advance as referred to in Section 29.5 and a positive decision has not been received from the Tax Authorities within a term acceptable to the

9 Company, the Company is entitled to settle the difference of net income with any financial payments due to you. Should there be insufficient funds to settle the full amount, you shall reimburse the Company directly. 29.7. You are solely responsible for the completion, content and accuracy of the information provided in and with the application form ‘Verzoek loonheffingen 30% regeling’, and in that regard you cannot hold the Company liable and indemnify the Company against any claims. 29.8. During the first 26 weeks of employment, in accordance with Section 628 sub section 5 of Book 7 of the Dutch Civil Code, you do not preserve the right to wages if you have not performed the contracted work due to a cause which, reasonably, should be for account of the Company, unless you are a so-called highly skilled migrant, in which case the aforementioned exclusion only relates to the amount of wages in excess of the minimum wage criterion applicable from time to time on the basis of article 1d ‘Besluit uitvoering Wet arbeid Vreemdelingen’. 29.9. This Clause 29 only applies as long as the 30%-ruling may be applied. If the 30%-ruling is no longer allowed or can no longer be applied (regardless of the reason) to you, the Company can immediately terminate this arrangement without the Company being liable towards you for payment of any damages or compensation otherwise. 30. Severance arrangements 30.1 In case the Company gives notice of termination of the employment contract before the term, or in case the court terminates the employment contract before the term, you are entitled to the following severance arrangements less any possible transitional compensation (transitievergoeding) as referred to in Section 7:673 of the Dutch Civil Code (BW) due by the Company, with the provision that if in that case the result is nil or negative, no severance payment will be paid and you are only entitled to the transitional compensation (transitievergoeding) as referred to in Section 7:673 of the Dutch Civil Code (BW), unless: a) notice of termination was given for urgent cause (dringende reden); b) notice of termination was given or termination was based on Section 7:669, paragraph 3, subsection e of the Dutch Civil Code (BW); c) the reason for notice of termination or termination is otherwise culpable to you; d) the employment contract ends by operation of law or because you reached the state pension age (AOW-gerechtigde leeftijd); or e) notice of termination was given or the employment contract was terminated during suspension of payment (surseance van betaling) of the Company or as a consequence of liquidation (faillissement) of the Company. 30.2 The severance is equal to the gross amount of six (6) times the fixed monthly salary of the Employee applicable on the last day of employment, with due observance of Section 30.1 of the employment contract.
