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
