between

 55131 Mainz, Langenbeckstraße 1, 

represented by 
 the chairman of the
executive board and the Medical Director, [***] 
 the Scientific Director, [***] as well as 

the Commercial Director [***] 

(hereafter called “Unimedizin”) 

and 
 BioNTech AG 

An der Goldgrube 12

 1 













 The contract parties agree to supplement the sublease agreement from 12.12.2012/ 14.01.2013, last amended
with the 1st supplementary agreement from 09.07.2014 and the 2nd supplementary agreement from 02.06.2015/ 08.06.2015 (hereafter together called
“sublease agreement”) with the following: 
 The owner of the building, Santo Service GmbH, formerly SANIPharma GmbH, has erected a four-storey
extension (ground floor to 3rd floor) in a second building section on the basement of the east wing already erected in the first building section. As per the existing and approved planning
application this extension consists of a laboratory and office facilities. The development of access roads and the supply of media such as electricity, heat, water etc. is realised via the existing building section. Unimedizin intends to
additionally lease these new lease areas from Santo Services GmbH and to sublet these to Biontech with this addendum. 
 Ganymed Pharmaceuticals GmbH,
formerly Ganymed Pharmaceuticals AG (hereafter called “Ganymed”) as well as Unimedizin and Biontech have also agreed in a termination agreement with effect from 01.11.2017 that the sublease agreement between Ganymed and Unimed will end on
01.11.2017 and Biontech will take over the facilities sublet by Ganymed. Unimedizin therefore intends to sublet all areas currently leased by Ganymed to Biontech with this addendum as well, so that Biontech is the sole subtenant for the building
with laboratory and administration facilities at An der Goldgrube 12 in 55131 Mainz. 
 The parties wish to agree the subletting period anew for the entire
lease object with this addendum. 
  

	 	1.	 The regulations stipulated in the sublease agreement continue to apply without limitation with the exception of
the newly agreed term according to point 2 below. Apart from that this addendum extends the sublease agreement by the newly added lease areas. 


  

	 	2.	 Section 4 no. 3 of the sublease agreement is herewith replaced as follows: 



The sublease relationship is limited to a period of ten years starting from 01.11.2017. Biontech is granted the option to extend the sublease
agreement three times, twice by a respective 5 years each, and a third option ending on 20.04.2039. Exercising the option must be declared in writing at least 18 months prior to expiry of the (possibly extended) lease agreement in writing in each
case. The receipt of the declaration by Unimedizin is crucial for compliance with this deadline. 
 Section 4 para. 2 of the sublease
agreement is deleted without replacement by ending the lease agreement between Ganymed and Unimedizin. 
 Should the financial managers
revise the economic allocation of the lease object for taxation purposes in such a way that Biontech is considered the economic owner, the contract partners and Santo Services GmbH are bound to negotiate a regulation that will not lead to
disadvantages or advantages for the contract parties.

submitted. 
  

	 	4.	 The rent according to Section 6 no. 1 of the sublease agreement, last amended with the with the [sic] 2nd supplementary agreement from 02.06.2015/ 08.06.2015, will now be, from 01.11.2017:

	 	5.	 The size of the security deposit according to Section 20 para. 2 of the sublease agreement is adjusted to
the sum of 3 monthly rent payments of the currently agreed monthly rent listed under point 5. 


  

	 	6.	 The 2nd building section will be completed in August 2017.



  

	 	7.	 Handover of the rooms of the east wing will take place following completion and will be recorded in a handover
protocol. The date of the handover will be agreed at least 3 weeks in advance. Appendix 1.2. 


 Handover of the
areas currently leased by Ganymed to Biontech will also be recorded in a handover protocol. Against the background of the fact that Ganymed will concede lease areas to Unimedizin, and Unimedizin will hand the same over to Biontech immediately
following this, the contract parties agree that the handover of the lease areas or facilities will take place directly from Ganymed to Biontech. Bintech [sic] will produce a handover protocol to record this together with Ganymed. 

 

	 	8.	 The respective room books and plans for the facilities of the east wing will be handed over during said
handover. Appendix 1.3. 


  

	 	9.	 The current Appendix 5 of the lease agreement concerning open spaces is replaced with the enclosed
Appendix 1.4.
