wages. 









	3.	The Employee will not be entitled to continued payment of wages during the aforementioned period if he caused the illness intentionally, if the illness ensued from an infirmity about which he gave the Employer false
information when he entered into the employment contract, if he causes an obstruction of or delay in the recovery process, or if the Employee refuses to perform other suitable work for the Employer or another (possibly affiliated) employer despite
being able to perform that work. 

  

	4.	The Employer will be entitled to postpone continued wage payments pursuant to paragraph 2 above if the Employee does not comply with the Employer’s reasonable instructions, issued in writing, concerning the

partners, proposed transactions, reports, plans, market prognoses, computer software, databases, data, technical knowledge, inventions, new technology, working methods, formula, processes, techniques, research data from laboratories, physical
materials (including all chemical or biological compounds or

or ownership and regardless of how the Employee learned of the particulars. 

  

	2.	Other than for the benefit of the Employer within the scope of the normal work, the Employee may also not copy, compile, merge, assemble or process information, products or systems of the Employer or disassemble,
reproduce or decompile the source code of the computer software included in those products or systems or attempt to deduce the source code of such software in any other manner. 


 

	3.	Notwithstanding the provisions of Article 7:650(3), (4) and (5) of the Dutch Civil Code, if the Employee violates the confidentiality clause contained in this Article he will forfeit to the Employer an

indirectly compete with the Employer or a company affiliated with it (being activities in the field of the development of human therapeutic anti-bodies, antibody fragments, any other engineered antibody-derived molecules, or any other alternative

	    	The Employee and the Employer undertake to discuss in good faith to which extent the above non-compete clause is reasonable in the context of the circumstances (including the reasons) of an intended departure of the
Employee and his intended future occupation and activities, provided always that the interests of the Employer and its business shall remain to be properly protected. 









	2.	Notwithstanding the provisions of Article 7:650(3), (4) and (5) of the Dutch Civil Code, if the Employee violates the non-competition clause contained in this Article he will forfeit to the Employer an
immediately due and payable penalty of € 25,000 for each violation, as well as a penalty of € 1,000 for each day that the violation continues, without prejudice to the Employer’s right to claim full compensation instead of

	3.	Notwithstanding the provisions of Article 7:650(3), (4) and (5) of the Dutch Civil Code, if the Employee violates the bans on recruitment contained in this Article he will forfeit to the Employer an
immediately due and payable penalty of € 25,000 for each violation, as well as a penalty of € 1,000 for each day that the violation continues, without prejudice to the Employer’s right to claim full compensation instead of
that penalty.

obligations, to administer employee benefits, including insurance and pension provisions, and to administer programmes and plans with respect to training and development, job assessment, compensation, planning and organisation. For these purposes
the Employer may also transfer the Employee’s personal data to other companies of the Employer located in countries inside and outside the European Union.

data it holds about him (although the Employee is welcome to review and update his personal data more or less frequently).

statutory obligations.

know-how, ensuing in the Netherlands or abroad, during or after this employment contract, from the work performed by the Employee under this employment contract (‘Intellectual Property Rights’) will exclusively vest in the Employer.


  

	2.	Insofar as any Intellectual Property Rights are not vested in the Employer by operation of law, the Employee covenants that he will transfer to the Employer at the Employer’s first request to that effect and,
insofar as possible, hereby transfers those rights to the Employer, which transfer is hereby accepted by the Employer. 









	3.	Insofar as any Intellectual Property Rights are incapable of being transferred from the Employee to the Employer, the Employee hereby grants the Employer the exclusive, royalty-free, worldwide, perpetual right, with the
right to grant sublicenses, to use those Intellectual Property Rights in the broadest sense, which right is hereby accepted by the Employer. 

  

	4.	Insofar as any personal rights vest in the Employee and insofar as permitted by law, the Employee hereby waives all of his personal rights, including but not limited to the right to have one’s name stated pursuant
to the Dutch Copyright Act of 1912 (Auteurswet 1912).

authority in the world.

and registration of the Intellectual Property Rights referred to in paragraphs 2 and 6. 

  

	8.	The Employee acknowledges that his salary includes reasonable compensation for the loss of intellectual and industrial property rights.

	1.	Upon this Agreement coming into force, the management agreement between the Employer and the Employee and/or his personal holding company, dated December 29, 2005, shall terminate. Subject only to receipt of the
final monthly payment pursuant to said management agreement, the Employee fully discharges the Employer in relation to said management agreement, and confirms that he shall hold the Employer harmless from any and all obligations, costs and expenses
pursuant to or in connection with the management agreement, including any liabilities of the Employer in relation to wage taxes, social security premiums and similar costs (including any penalties) in relation to the entire period that the Employee
and his personal holding company has performed services under such management agreement.
