All these Results shall accrue to the Employer, also if not explicitly mentioned in, or provided for by this employment agreement. The same applies if these Results have been realised outside the official working hours of the Employee. The Employee hereby transfers all current and future Results that do not already accrue to the Employer in a different way. All Results that have thus been transferred or otherwise accrue to the Employer include the Results in their most comprehensive form and application, including any future applications. The Employee shall fully cooperate in the realisation of the transfer of the Results and the realisation of a worldwide intellectual property protection for this purpose. To this end, the Employee grants the Employer in advance an irrevocable and unconditional power of attorney to perform all relevant acts or sign documents in his name.

11.2The Employee waives his right to patents as set out in Section 12 (1) of the Dutch Patent Act (‘DPA’). The equitable remuneration contemplated by Section 12 (6) DPA is deemed by the Parties to this employment agreement to be included in the Employee’s salary. The Employee shall not claim any further compensation for loss of patent. To avoid misunderstandings: the power of attorney mentioned in the previous article also includes the right of the Employer to submit patent applications in the Employee’s name in territories where this is necessary.

11.3If the Employee has any moral rights (such as attribution or opposition against change) with regard to the Results, the Employee hereby waives these rights, in so far as permitted by law.

17.1In the event of termination of this employment agreement at the initiative of the Employer, or termination at the initiative of the Employee, due to a change of circumstances that is of such a nature that it cannot be required of the Employee to remain employed by the Employer (for example, but not limited to, the occurrence of a merger or acquisition by which the Employee’s position will change substantially, or in which context another director will be appointed, causing the Employee’s responsibilities to decrease substantially), the Employer will have to pay the Employee the compensation as specified below in this article 17 (the “Severance Compensation”).

17.2The Employee will not be entitled to a Severance Compensation if the employment agreement is terminated at the Employer’s initiative through a legally valid summary dismissal, for an urgent reason that was promptly notified to him as envisaged in Section 7:677 (1) Dutch Civil Code, or if the employment is terminated at the initiative of the Employer due to a (seriously) culpable act or omission by the Employee.
