Dear Dr. Ullrich,


In a letter from 05/30/2013 you informed us that 4-Antibody AG expressed the wish to extend the lease till 06/30/2016.


The extension is approved if the company is still a KMU [small or medium-sized company] at the time of extension, continues to pay a competitive rent, and there are no other small and medium-sized companies that need to use the spaces.


If you have any questions, please do not hesitate to contact us.


Kind regards,






Daniel Korn
Administrator

4-Antibody AG Lease at BioInstrumentezentrum
Your letter from 10/05/2010


Dear Ms. Sindermann:


4-Antibody AG has exercised its option right from the approved lease and, at the same time, expressed the wish to extend no only till 02/28/2016, but at once till 06/30/2016.


Since the underlying conditions for extension did not change at all in 2010, from my perspective, I support the application of 4-Antibody AG to extend the lease till 06/30/2016 on the same conditions that you informed us of in your letter from 05/10/2010.
We sent you the respective lease agreement on 12/30/2010.


If you have any objections to this action, I kindly ask you to inform us of this by 06/07/2013. Otherwise, I will proceed as described above.


Kind regards,


BioCentiv GmbH
