prudent and conscientious business manager pursuant to the provisions of law, the Articles of Association, the Rules of Procedure for the Board of Managing Directors as issued by the Supervisory
Board, and this Agreement. He shall safeguard the Company’s interests and shall devote his full working capacity exclusively to the Company. 

  

	2.	In connection with this Agreement and, unless explicitly agreed otherwise in writing, without any additional remuneration, the CSO shall, upon request of the Company, also assume or resign functions in other enterprises
which are affiliated with the Company (sec. 15 German Stock Companies Act (AktG)). This shall apply accordingly with respect to honorary functions in associations and professional organizations, in which the Company or an affiliated company is a
member. 

  

	3.	The Company is entitled to release the CSO at any time from his work with the continued payment of his gross basic remuneration according to § 4 (1) until the end of the term of this Agreement and while
offsetting his residual entitlement to vacation. 

  

	4.	The place of work is Freising. 

 § 3 

Working hours 
  

	1.	The CSO shall dedicate his entire working capacity to the Company, at least 40 hours a week. The duration and the starting and finishing times of the daily working hours shall be determined by the CSO in consultation
with his Executive Management (Vorstand) colleagues, and according to his set task within the respectively valid local working hours regulations, in which respect he must take account of operational interests and the respectively valid
Company regulations. 

  

	2.	The CSO is obliged to do overtime or additional work. Overtime is to be done as is required by the situation-related scope of work and in so far as this is legally permissible. The additional work is compensated by the
regular salary according to § 4 (1). 

 § 4 

Salary, other benefits 
  

	1.	The CSO shall receive for his contractual employment an annual gross salary of EUR 210,000.00 (in words: Euro two-hundred thousand ten), payable in twelve (12) equal monthly instalments through transfer to the
account to be designated by the CSO with a bank located within Germany. The aforementioned instalments will be paid the last day of each month.

within 5 business days after execution of this Agreement, through transfer to the bank account to be designated by the CSO. 

  

	3.	In addition, the CSO shall receive for his contractual employment an annual car allowance of EUR 10,000.00 (in words: Euro ten thousand) gross, payable in twelve (12) equal monthly installments at the time of his

	4.	In addition to the remuneration provided for under §§ 4 (1)-(3), dependent upon the achievement of certain targets to be agreed on between the Parties, the CSO shall receive an annual bonus payment of EUR
30,000.00 (in words: Euro thirty thousand) gross (the “Annual Bonus”). The Annual Bonus will be paid each year at year’s end, i.e. December 31, and will be paid pro rata temporis if the employment has not existed the
entire year depending on the achievement of the agreed targets, whereby the determination of the fulfilment of the agreed targets is within the sole discretion of the Company. The Company guarantees a bonus in the amount of 50% of the Annual Bonus
for the calendar year in which the employment has started, i.e. 2010. 

  

	5.	The CSO shall be eligible to participate in the existing option pool in such way that the CSO shall be granted a stake of 1.5% (one and one-half percent) in the Company (the “Exit Fee”) in the event of a sale
of the shares in the Company or a sale of the assets of the Company (the “Exit”) during the Term (which, for the sake of clarity, shall include any Extended Term). The Exit Fee shall be paid to the CSO promptly upon receipt of funds by the
Company and in the form and ratio of consideration (i.e., cash or securities) commensurate with the form and ratio of consideration paid by the acquiring entity. If the CSO has been in active employment with the Company for at least six months he
will receive (a) 100% of the Exit Fee if the Exit occurs within 6 (six) months after termination of this employment either because of a notice of termination provided by the Company or because the Company was not prepared to extend this
Agreement and (b) 50% of the Exit Fee if the Exit occurs within 12 (twelve) months after termination of the employment either because of a notice of termination provided by the Company or because the Company was not prepared to extend this
Agreement. If the CSO provides notice of termination of employment in accordance with § 1 (1) or if the CSO is not prepared to accept the Company’s offer to extend this Agreement beyond the Term, then the CSO shall not be entitled to
an Exit Fee for an Exit occurring after the Term. 

  

	6.	In case of an additional dilutive financing round by the Company, the Exit Fee may be adjusted by the supervisory board accordingly, in good faith. 


 

	7.	The Company shall incur (either directly or by reimbursing the CSO upon submission of the respective receipts) the relocation costs incurred to the CSO due to the relocation from his current domicile to a domicile near
Freising (collectively, the “Relocation Costs”). The Relocation Costs shall be limited to those costs incurred up to 18 (eighteen) months after the Effective Date and to a maximum of EUR 60,000 (in words: Euro sixty thousand).


  

	8.	The CSO undertakes to repay any overpayments of salary, including claims arising from the incorrect calculation of taxes and voluntary benefits, to the Company without delay. The CSO waives in this respect the assertion
of a plea of a loss of enrichment according to § 818 (3) of the German Civil Code (Bürgerliches Gesetzbuch).
