2.1. Exclusive License from BioNTech to Pfizer. Subject to the terms and conditions of this Agreement, effective as of the
Effective Date, BioNTech on behalf of itself and its Affiliates hereby grants (and will procure that its Affiliates grant) to Pfizer an exclusive (exclusive even as to BioNTech and its Affiliates except to the extent necessary (a) to perform
BioNTech’s activities under the Research Plan during the Research Term and (b) to Manufacture Clinical Trial Material as provided in this Agreement or the Supply Agreement) sublicensable (through multiple tiers) license and, to the extent
any BioNTech Technology is Controlled by BioNTech or its Affiliates pursuant to a BioNTech Third Party Agreement existing as of the Effective Date and, subject to Section 2.9, Future BioNTech Third Party Agreements, a sublicense, as applicable,
under the BioNTech Technology and BioNTech’s and its Affiliates’ interest in the Research Program Technology (including any BioNTech Improvements), to use, have used, Develop, have Developed, Manufacture, have Manufactured, Commercialize,
have Commercialized and otherwise Exploit Candidates, Products and [***] in the Territory. Without prejudice to Section 2.10.2, the foregoing license shall not prevent BioNTech and its Affiliates from conducting internal research directed
outside the Field where flu antigens or BioNTech Technology are used solely as comparators in such research. For avoidance of doubt, [***]: (i) which is not a Candidate or Product, (ii) which is Exploited by Pfizer under the foregoing license,
and (iii) the Exploitation of which would, absent such foregoing license, infringe a valid claim under the BioNTech Patent Rights or BioNTech’s rights in the Research Program Patent Rights (with “valid claim” being construed by
applying Section 1.119 mutatis mutandis) shall be considered a Candidate or Product for the purposes of this Agreement. 
 2.2.
Non-Exclusive License from BioNTech to Pfizer. Without limiting any other license or sublicense granted under this Agreement and subject to the terms and conditions of this Agreement, BioNTech on
behalf of itself and its Affiliates, effective as of the Effective Date, hereby grants (and will procure that its Affiliates grant) to Pfizer a non-exclusive, royalty-free, fully
paid-up, sublicensable license and, to the extent any BioNTech Technology is Controlled by BioNTech or its Affiliates pursuant to a BioNTech Third Party Agreement existing as of the Effective Date and, subject
to Section 2.9, Future BioNTech Third Party Agreements, a sublicense, as applicable, under all Patent Rights, Know-How and other Intellectual Property Rights Controlled by BioNTech or its Affiliates and
existing as of or after the Effective Date (to the extent such Patent Rights, Know-How and other Intellectual Property Rights are not exclusively licensed or sublicensed to Pfizer pursuant to
Section 2.1), to use, have used, Develop, have Developed, Manufacture, have Manufactured, Commercialize, have Commercialized and otherwise Exploit Candidates and Products in the Field in the Territory during the Term. 

  
 18 













 2.3. Additional Licenses. 

2.3.1. To Pfizer. 

Without limiting any other license or sublicense granted under this Agreement and subject to the terms and conditions of this Agreement,
BioNTech on behalf of itself and its Affiliates, effective as of the Effective Date, hereby grants (and will procure that its Affiliates grant) to Pfizer a non-exclusive, royalty-free, fully paid-up, sublicensable license under all BioNTech Improvements that were solely or jointly invented by Pfizer Representatives to use, have used, Develop, have Developed, Manufacture, have Manufactured,
Commercialize, have Commercialized and otherwise Exploit any products or processes in any field. In addition to the obligations set forth in Section 2.10 for the avoidance of doubt, the license granted in this Section 2.3.1 shall not
include or imply a right of Pfizer to use any BioNTech’s Confidential Information (that is not a BioNTech Improvement) outside the Field. 

2.3.2. To BioNTech. 

(a) Without limiting any other license or sublicense granted under this Agreement and subject to the terms and conditions of
this Agreement, Pfizer, effective as of the Effective Date, hereby grants to BioNTech a non-exclusive, royalty-free, fully paid-up, sublicensable license under all
Pfizer Improvements that were solely or jointly invented by BioNTech Representatives to use, have used, Develop, have Developed, Manufacture, have Manufactured, Commercialize, have Commercialized and otherwise Exploit any products or processes
outside the Field. 
 (b) Without limiting any other license or sublicense granted under this Agreement and subject to the
terms and conditions of this Agreement, Pfizer, effective as of the Effective Date, hereby grants to BioNTech a non-exclusive, royalty-free, fully paid-up, sublicensable
license under (i) all RNA Improvements and (ii) Pfizer’s interest in the Research Program Technology, in each case of (i) and (ii) to use, have used, Develop, have Developed, Manufacture, have Manufactured, Commercialize, have
Commercialized and otherwise Exploit any products or processes outside the Field. 
 (c) For the avoidance of doubt, the
licenses granted in this Section 2.3.2 shall not include or imply a right of BioNTech to use any Pfizer Confidential Information (that is not a Pfizer Improvement, RNA Improvements or Research Program Technology). 

2.4. Pfizer Sublicensees. Pfizer will have the right through multiple tiers to grant sublicenses and, as applicable, sub-sublicenses to its Affiliates and Third Parties of any and all rights granted to Pfizer under this Agreement by BioNTech, including any and all rights licensed to Pfizer pursuant to Section 2.1 or
Section 2.2. In respect of such sublicenses (or sub-sublicenses): 
 (a) Pfizer
will remain responsible for the payment to BioNTech of all Sales Milestone Payments and royalties payable under this Agreement with respect to Net Sales of Products made by such Pfizer Affiliates or Sublicensees; 

(b) Pfizer shall be responsible for failure by its Sublicensees to comply with the terms and conditions of this Agreement; 

(c) Pfizer shall notify BioNTech in writing of any sublicenses granted to Third Parties and, upon BioNTech’s written
request, provide BioNTech with a written summary of key terms of the respective sublicense agreement (excluding any terms reasonably deemed commercially sensitive or confidential by Pfizer); and 

  
 19 













 (d) Unless otherwise agreed between the Parties on a case-by-case basis (e.g. with a view of converting certain sublicenses into direct licenses with BioNTech), all sublicenses shall automatically terminate (and Pfizer shall
ensure that all sublicenses automatically terminate) upon termination (for whatever reason) of a license granted hereunder, but only to the extent necessary to terminate the sublicense in so far as it corresponds to any terminated licenses granted
in this Agreement. 
 2.5. Direct Licenses to Affiliates. Pfizer may, from time to time, request that BioNTech grants on
behalf of itself and its Affiliates (and will procure that its Affiliates grant) licenses or sublicenses directly to Affiliates of Pfizer by giving written notice, upon receipt of which BioNTech and its Affiliates will enter into and sign a separate
direct license or sublicense agreement with such designated Affiliate of Pfizer. All such direct license or sublicense agreements will be consistent with the terms and conditions of this Agreement, except for such modifications as may be required by
applicable Laws in the country in which the direct license or sublicense will be exercised. The Parties further agree to make any amendments to this Agreement that are necessary to conform the combined terms of such direct licenses or sublicenses
and this Agreement to the terms of this Agreement as set forth on the Execution Date. All reasonable costs of making such direct license or sublicense agreement(s), including BioNTech’s reasonable attorneys’ fees, under this
Section 2.5 will be borne by Pfizer. 
 2.6. Non-Exclusive License from Pfizer to
BioNTech. Subject to the terms and conditions of this Agreement, Pfizer hereby grants to BioNTech a non-exclusive, royalty-free, fully paid-up license in the
Territory in the Field, with no right to grant sublicenses other than to its Affiliates, and to permitted subcontractors under Section 4.2.2, under the Pfizer Technology solely: (i) during the Research Term to the extent necessary to
perform BioNTech’s activities under the Research Plan; and (ii) to the extent necessary to Manufacture Clinical Trial Material as provided in this Agreement or the Supply Agreement. 

2.7. Right of Reference. BioNTech on behalf of itself and its Affiliates hereby grants (and will procure that its Affiliates grant) to
Pfizer, its Affiliates and its Sublicensees a “Right of Reference,” as that term is defined in 21 C.F.R. § 314.3(b) (or any analogous Law recognized outside of the United States), to all data (including any regulatory filings or
Regulatory Approvals) Controlled by BioNTech or its Affiliates that relates to any Candidate or Product, and BioNTech will provide a signed statement to this effect, if requested by Pfizer, in accordance with 21 C.F.R. § 314.50(g)(3) (or any
analogous Law outside of the United States). 
 2.8. Current Licenses. 

2.8.1. Maintenance of Current Licenses. BioNTech will maintain in full effect and will perform all of its obligations in
a timely manner under each of the Current Licenses. Absent Pfizer’s prior written consent (which may be provided, conditioned or withheld in Pfizer’s sole discretion), BioNTech will not terminate, modify or amend any Current License in any
manner that would adversely affect any of the rights granted or that may be granted to Pfizer under this Agreement or that would impose any obligations upon Pfizer hereunder that are in addition to those obligations that would exist under this
Agreement based on the Current Licenses as they exist on the Effective Date or adversely affect BioNTech’s ability to perform its obligations under this Agreement. Further, BioNTech will not take any action or omit to take any action that would
cause it to be in breach of any Current License or that would give rise to a right of any Current Licensor to terminate the applicable Current License. 

  
 20 













 2.8.2. Communications and Performance. Notwithstanding anything to
the contrary in this Agreement, BioNTech will use Commercially Reasonable Efforts to facilitate any communications between Pfizer and any Current Licensor required for Pfizer to exercise the rights granted to it pursuant to Section 2 and will use
Commercially Reasonable Efforts to cause each applicable Current Licensor to perform all of its obligations under the applicable Current License. 

2.8.3. Breach of Current License by BioNTech. If BioNTech receives notification of any actual or potential breach or
otherwise becomes aware of its breach of any Current License (and if uncured, such breach could give rise to the termination of the applicable Current License), then BioNTech will immediately notify Pfizer of such breach. To the extent that any act
or omission on the part of Pfizer is the cause of such breach of a Current License, Pfizer will take all actions and provide BioNTech with all cooperation necessary to cure such breach, in each case as reasonably requested by BioNTech and at
Pfizer’s sole cost and expense. To the extent that Pfizer is not the cause of such breach of a Current License, BioNTech will have the first opportunity to cure such breach in accordance with a plan to be mutually agreed upon by the Parties in
writing, acting reasonably (each, a “Cure Plan”). If (a) BioNTech, at any time, is not using diligent efforts to cure such breach pursuant to the applicable Cure Plan or (b) BioNTech is unable to cure such breach in
accordance with the applicable Cure Plan or it becomes reasonably apparent that BioNTech will not be able to cure such breach pursuant to the applicable Cure Plan, then Pfizer may, at its election and in its sole discretion and without prejudice to
its other remedies against BioNTech, act reasonably to cure such breach and BioNTech will take all actions and provide Pfizer with all cooperation to cure such breach, in each case as directed by Pfizer. Further, if Pfizer is not the cause of such
breach of a Current License, then BioNTech will, at Pfizer’s sole election, (i) reimburse Pfizer for all out-of-pocket costs and expenses incurred by or on
behalf of Pfizer or any of its Representatives in connection with curing such breach; or (ii) permit Pfizer to offset any such costs and expenses incurred by or on behalf of Pfizer or any of Pfizer’s Representatives in connection with
curing such breach against Pfizer’s future payment obligations to BioNTech (or any of its successor or assigns) under this Agreement. 

2.8.4. Termination of any Current License. In the event that any Current License is terminated by the applicable Current
Licensor and this Agreement, as of the effective date of such termination, has not otherwise been terminated, Pfizer, to the extent permitted by such Current License (or if not permitted or addressed in such Current License, to the extent permitted
by the applicable Current Licensor), will have the right without prejudice to its other remedies against BioNTech, at Pfizer’s election, to convert the sublicenses granted under this Agreement by BioNTech to Pfizer under such Current License to
a direct license from the applicable Current Licensor to Pfizer on the terms and conditions contained in such Current License (with Pfizer assuming the applicable obligations of BioNTech thereunder) or such other terms and conditions as may be
negotiated by Pfizer and the applicable Current Licensor. In the event Pfizer enters into any such direct license with a Current Licensor, BioNTech will, at Pfizer’s sole election and without prejudice to its other remedies hereunder: 

  
 21 













 (a) in respect of royalties payable by Pfizer under such direct license to
the Current Licensor, to the extent such royalties are due in connection with the sale of Candidates or Products hereunder, reimburse to Pfizer the difference between (i) the amount that would have been payable by BioNTech to the Current
Licensor under the Current License if the Current License had not been terminated and (ii) the account that would have to be reimbursed by Pfizer to BioNTech in accordance with Section 3.5.3(b) in relation to the Current License if the Current
License had not been terminated; or 
 (b) permit Pfizer to offset any such reimbursement amounts (to the extent not
reimbursed pursuant to clause (a) above), against Pfizer’s future payment obligations to BioNTech (or any of its successor or assigns) under this Agreement. 

2.8.5. Consents and Waivers. BioNTech represents, warrants and covenants to Pfizer that, to the extent any terms and
conditions of this Agreement do not (or will not at any time during the Term) conform to any requirements relating to the grant of sublicenses under any Current License, it has obtained the irrevocable consent (or, if applicable, the waiver of any
resultant conflict) from the applicable Current Licensor that is necessary to permit the activities contemplated under this Agreement, including, such that BioNTech may grant the applicable sublicenses granted or to be granted hereunder and perform
all of its obligations hereunder and Pfizer may exercise all of its rights and perform all of its obligations hereunder, in each case, without breaching the applicable Current License. In the event that any provision in any Current License which
conflicts with this Agreement or adversely impacts the activities contemplated under this Agreement comes to the attention of either BioNTech or Pfizer or which otherwise, at any time during the Term, would cause the representation, warranty and
covenant set forth in the preceding sentence to be untrue, BioNTech, in consultation with Pfizer, will obtain any and all additional required consents or waivers from the applicable Current Licensor(s) which may be necessary to align the conflicting
provision(s) of the applicable Current License with this Agreement and to permit the activities contemplated by this Agreement. 
 2.9.
Future BioNTech Third Party Agreements. If BioNTech enters into bona fide discussions with a Third Party after the Effective Date which would, if an agreement is finally executed with such Third Party, give BioNTech rights to any Intellectual
Property Rights that could reasonably be applicable to the Candidates or Products in the Field, then BioNTech shall notify the JSC for discussion pursuant to Section 4.3.2(d)(vii). Any Intellectual Property Rights Controlled by BioNTech
pursuant to a BioNTech Third Party Agreement executed between BioNTech and such Third Party (each, a “Future BioNTech Third Party Agreement”) shall only be included in the licenses granted to Pfizer under this Agreement if and when
Pfizer: (a) notifies BioNTech in writing that such Intellectual Property Rights be included in the licenses granted to Pfizer under this Agreement; (b) agrees to reimburse BioNTech [***] of the royalties payable by BioNTech to the Third Party
Licensor under such Future BioNTech Third Party Agreements (i) solely to the extent such royalties are due in connection with the sale of Candidates or Products hereunder and (ii) provided that the [***] cap on royalties payable by Pfizer
to BioNTech set forth in Section 3.5.3(b)(y) shall not apply in respect of such reimbursement; and (c) agrees to comply with the terms of such Future BioNTech Third Party Agreement applicable to Pfizer as a sublicensee. BioNTech shall not
in any circumstance conclude any agreement with a Third Party so as to prevent Pfizer gaining access to such Third Party’s Intellectual Property Rights within the Field for any Candidate or Product. 

2.10. No Implied Rights. Except as expressly provided in this Agreement, neither Party will be deemed to have granted the other
Party (by implication, estoppel or otherwise) any right, title, license or other interest in or with respect to any Patent Rights, Know-How or other Intellectual Property Rights or information Controlled by
such Party. 

  
 22 













 2.10.1. Exclusivity. 

2.10.2. Except for the Research Program, during the Term, BioNTech shall not, and shall procure that its Affiliates shall not
Develop, have Developed, Manufacture, have Manufactured, Commercialize, have Commercialized or otherwise Exploit or have Exploited any [***] itself or with or on behalf of a Third Party in the Field, except that BioNTech may continue any BioNTech
Third Party Agreement for non-clinical research in the Field with academic institutions and consortia. As of the Effective Date, BioNTech shall not (and shall procure that its Affiliates shall not) enter into
any new agreements with any Third Party in the Field without a discussion at and pre-approval by the JSC pursuant to Section 4.3. 

2.10.3. During the Research Term, Pfizer and its existing Affiliates shall not enter into any research collaboration or other
license agreement with [***] unless and until the JSC mutually agrees pursuant to Section 4.3. For avoidance of doubt, the foregoing exclusivity obligation shall not apply to any agreement with a Third Party possessing supplementary technology
to RNA that may enhance the efficiency of a Candidate or Product in the Field, including bioinformatics, automation, DNA synthesis, formulations, selection of epitopes, syringe or other delivery device companies, or the like. 

Notwithstanding the foregoing, if a Change of Control occurs with respect to Pfizer and a Third Party during the Research Term, or if Pfizer or
any of its existing Affiliates acquires or merges with a Third Party during the Research Term, and such Third Party is, at the time of such Change of Control or acquisition or merger, conducting activities that would cause Pfizer or one of its
Affiliates to violate this Section 2.10.3 (such activities, a “Acquisition Program”), then Pfizer or such Third Party shall be permitted to continue such Acquisition Program and such continuation will not constitute a violation of
this Section 2.10.3; provided that (a) no Confidential Information of BioNTech or its Affiliates is used in such Acquisition Program and (b) Pfizer shall implement and maintain, in accordance with Pfizer’s internal commercially
reasonable practices, an information barrier between the working teams involved in the day to day conduct of Pfizer’s internal program of Development and Manufacture of Candidates and Products under this Agreement and the equivalent teams under
such Acquisition Program. 
 2.11. Right of First Refusal. Commencing on the Effective Date and expiring on the [***] anniversary
thereof (“ROFR Term”), BioNTech on behalf of itself and its Affiliates hereby grants (and procures the grant to) Pfizer the exclusive right of first refusal (“Right of First Refusal”) to acquire a worldwide,
exclusive license, with the right to sublicense (through multiple tiers), under Intellectual Property Rights Controlled by BioNTech and its Affiliates to use, have used, Develop, have Developed, Manufacture, have Manufactured, Commercialize, have
Commercialized and otherwise Exploit immunogenic compositions comprising RNA that encodes at least one Antigen for prophylaxis against respiratory syncytial virus (“RSV”) or human cytomegalovirus (“hCMV”) in the
Territory (each a “Partnered Field” and collectively, the “Partnered Fields”) as follows: 

2.11.1. During the ROFR Term,BioNTech shall notify Pfizer in writing before it or any Affiliate enters into an agreement with a
Third Party in the Territory in one or both of the Partnered Fields. BioNTech’s writing shall identify the Partnered Field(s) and provide reasonable details of the terms of the proposed agreement with the Third Party, including the financial
terms, and a written report in reasonable detail of any of BioNTech’s and its Affiliates’ existing data that may be relevant to candidates/products in the Partnered Field( s) that Pfizer is otherwise unaware of


  
 23 













 
(“BioNTech ROFR Notice”), and, if Pfizer so requests, BioNTech shall provide access to the same set of data and information that such Third Party has had access via a data room
or other means. For avoidance of doubt, if BioNTech’s written notice applies to only one Partnering Field, then Pfizer’s Right of First Refusal for the other Partnering Field shall not be affected and continue to apply. 

2.11.2. Within [***] days after receiving a BioNTech ROFR Notice, Pfizer shall respond in writing as to whether Pfizer has a
good faith desire to obtain such rights on the same terms as set out in the BioNTech ROFR Notice. If Pfizer responds in the negative, or fails to respond within the [***] days, then Pfizer shall have no further rights under this Section 2.11 as
to the applicable Partnering Field(s), provided however, that under no circumstances may BioNTech nor its Affiliate during the ROFR Term enter into an agreement with a Third Party with respect to such Partnering Field(s) containing terms, taken as a
whole, that are more favorable to such Third Party than the terms and conditions set forth in the BioNTech ROFR Notice. 

2.11.3. If Pfizer responds in the affirmative within the [***] days, then this shall commence a [***] day period (“ROFR
Negotiation Period”) of good faith exclusive negotiations between the Parties acting reasonably as to the terms upon which BioNTech would partner with or license to Pfizer in the applicable Partnering Field(s) (“ROFR Partnering
Terms”). During the ROFR Negotiation Period, BioNTech shall not and shall procure its Affiliates shall not negotiate with any Third Party the terms upon which BioNTech or its Affiliates would partner with or license to such Third Party in
the Partnering Field(s). If the Parties are unable to agree on the ROFR Partnering Terms and conclude a respective definitive written agreement during the ROFR Negotiation Period, then Pfizer shall have no further rights under this Section 2.11
as to the Partnering Field(s), provided, however, that under no circumstances may BioNTech nor its Affiliates during the ROFR Term enter into an agreement with a Third Party with respect to such Partnering Field(s) containing terms, taken as a
whole, that are more favorable to such Third Party than the terms and conditions set forth in the BioNTech ROFR Notice. 

2.11.4. The ROFR excludes agreements for research in the Field with academic institutions and consortia, which are subject to
JSC approval under Section 4.3.2(d). 
 2.12. Right of First Negotiation. Effective as of the expiration of the ROFR Term and
terminating as of the expiration of the Research Term (“ROFN Term”), if BioNTech or its Affiliate elects to license or otherwise grant rights to a Third Party under Intellectual Property Rights Controlled by BioNTech or its
Affiliates in Partnering Field(s), then Pfizer shall have a right of first negotiation with respect to the first license or other partnership agreement for each of the Partnering Field(s) (“Right of First Negotiation”) as follows:

 2.12.1. During the ROFN Term, upon the request of the JSC, such request not to be made more than twice per Calendar Year,
BioNTech shall provide the JSC with an oral summary regarding any Development activities it may have conducted or is planning to conduct in respect of the Partnering Fields. During the ROFN Term, (a) if Pfizer provides BioNTech with a written notice
electing the Right of First Negotiation with respect to one or both Partnering Fields or (b) prior to BioNTech entering into bona fide negotiations with a Third Party with respect to the negotiation of a definitive legal agreement for a grant
of rights to Intellectual Property Rights Controlled by BioNTech and its Affiliates for the Partnering Field(s), BioNTech shall first notify Pfizer in writing. BioNTech’s written notice shall identify the Partnered Field(s) and provide a


  
 24 













 
written report in reasonable detail of any of BioNTech’s and its Affiliates’ existing data that may be relevant to candidates/products in the Partnered Field(s) that Pfizer is otherwise
unaware of (“BioNTech ROFN Notice”), and, if Pfizer so requests, provide access to any relevant data and information via a data room or by other mutually agreed upon means. For avoidance of doubt, if BioNTech’s written notice
applies to only one Partnering Field, then Pfizer’s Right of First Negotiation for the other Partnering Field shall not be affected and shall continue. 

2.12.2. Within [***] days after receiving a BioNTech ROFN Notice, Pfizer shall respond in writing as to whether Pfizer elects
to negotiate terms with BioNTech. If Pfizer responds in the negative, or fails to respond within the [***] days, then Pfizer shall have no further rights under this Section 2.13, as to the applicable Partnering Field(s). If Pfizer elects to
commence a ROFN or responds to a ROFN Notice in the affirmative within the [***] days, then this shall commence an exclusive [***] day negotiation period (“ROFN Negotiation Period”) during which the Parties shall negotiate, in good
faith and acting reasonably, a definitive written agreement between the Parties as to the terms upon which BioNTech and its Affiliates would partner with or license to Pfizer Intellectual Property Rights Controlled by BioNTech and its Affiliates for
the Partnering Field(s) (“ROFN Partnering Terms”). During the ROFN Negotiation Period, BioNTech shall not and shall procure its Affiliates shall not negotiate with any Third Party the terms upon which BioNTech or its Affiliates
would partner with or license to such Third Party Intellectual Property Rights Controlled by BioNTech and its Affiliates for the Partnering Field(s).If the Parties are unable to agree on the ROFN Partnering Terms and do not conclude a respective
definitive written agreement during the ROFN Negotiation Period, then the ROFN Negotiation Period shall expire and BioNTech shall be free to continue discussions with Pfizer or institute discussions on the same opportunity for the applicable
Partnering Field(s) with Third Parties. For clarity, the Right of First Negotiation set forth in this Section 2.12 shall apply a maximum of [***] times only; once for each of the RSV and hCMV fields. 

2.13. Access to Other BioNTech Technology. From time to time, Pfizer may, in addition to the licences granted hereunder, request a
license from BioNTech to Other BioNTech Technology for use in a Candidate or Product in the Field as Pfizer may identify, such license to be of comparable scope and comparable terms to the licenses granted under Sections 2.1 in respect of Candidates
and Products in the Field.For the purposes of this Agreement, “Other BioNTech Technology” means those Intellectual Property Rights Controlled by BioNTech or its Affiliates from time to time that do not constitute BioNTech Know-how or BioNTech Patent Rights.Upon Pfizer’s election for such as license, the Parties shall negotiate such license terms in good faith and acting reasonably (which shall be based on the terms of this
Agreement) for a period of not more than [***] days and BioNTech shall neither seek nor require any royalty rate or other financial provisions greater than (i) the mean royalty rate due to BioNTech by other licensees of the same Other BioNTech
Technology (reasonably adjusted in so far as it is licensed with other Intellectual Property Rights) in existence as of the date of any notice electing for such a licence pursuant to this Section or (ii) if no such other licenses are in
existence as of the date of such notice, the average royalty rate applied in comparable license agreements for similar technologies in the market.Any such license fees agreed pursuant to this Section shall be deemed license payments due under
Additional Third Party Licenses for the purposes of Section 3.5.3(a) and accordingly Pfizer shall be entitled to deduct [***] of such license fees. If, however, the Parties cannot reach an agreement within such [***] day period, then the terms
of such license for such Other BioNTech Technology shall be determined, taking into account all then-relevant factors including the provisions of this Section 2.13, by an independent Third Party expert knowledgeable in pharma licensing to be
agreed between the Parties (and if the Parties cannot agree on such Third Party expert within [***]days of the expiration of the above negotiation period, the Third Party expert shall be 

  
 25 













 
independently appointed upon either Party`s request by the International Chamber of Commerce). Each Party shall be obliged to submit its final proposal for the terms of such transition of or
license to the Other BioNTech Technology to the Third Party expert, and such proposal shall remain confidential and shall not be disclosed to the other Party. The decision of the Third Party expert shall be final and binding on both Parties. The
costs of the Third Party Expert shall be borne by both Parties at equal shares.

	(vii)	  	First Commercial Sale of such Product by Pfizer, its Affiliates or Sublicensees in the United States	  	[***]
			
	(viii)	  	First Commercial Sale of such Product by Pfizer, its Affiliates or Sublicensees in at least three of the Major EU Market Countries	  	[***]
			
	(ix)	  	First Commercial Sale of such Product by Pfizer, its Affiliates or Sublicensees in Japan	  	[***]

 Each of the Development Payments set forth above will be payable one time only (regardless of the number of Candidates or
Products with respect to which, or the number of times with respect to any Candidate or Product, the specified Development Event occurs). No Development Payments will be payable by Pfizer for any subsequent Candidate or Product regardless of the
number of Candidates or Products Developed. For clarification, if one Candidate or Product replaces another Candidate or Product in Development, then such replacement Candidate or Product will only be subject to Development Payments that have not
previously been triggered by one or more prior Candidates or Products. The maximum amount payable by Pfizer under this Agreement with respect to all Development Payments if all Development Events occur will be [***]. 

If Pfizer achieves one of the Development Events set forth in rows (iii), (iv) or (vi) of the table set forth in Section 3.3, but had not achieved
the preceding Development Event set forth (as applicable) in rows (iii) or (iv) of the table set forth in Section 3.3, then those preceding Development Event(s) set forth (as applicable) in rows (iii) or (iv) of the table set forth in
Section 3.3 shall be deemed to have occurred and all Development Payments for such preceding Development Event(s) shall become payable. If Pfizer achieves one of the Development Events set forth in rows (vii), (viii) or (ix) of the table
set forth in Section 3.3, but had not achieved any of Development Events set forth in rows (iii), (iv) or (vi) of the table set forth in Section 3.3, then those Development Event(s) set forth (as applicable) in rows (iii), (iv) or
(vi) of the table set forth in Section 3.3 shall be deemed to have occurred and all Development Payments for such Development Event(s) shall become payable. Notwithstanding the foregoing, Pfizer’s achievement of one of the Development
Events set forth in rows (iii), (iv), ( vi), (vii), (viii) or (ix) of the table set forth in Section 3.3 in response to a request by a Governmental Authority or Regulatory Authority to perform such Development Event due to pandemic flu
emergency conditions shall not trigger the payment of any preceding Development Event. 
 3.4. Sales Milestone Payments. Pfizer will
pay BioNTech RNA the following one-time payments (each, a “Sales Milestone Payment”) when aggregate Net Sales of all Products on which royalties have been paid to BioNTech under
Section 3.5.1 in a Pfizer Year in the Territory (the “Total Annual Net Sales”) first reach the respective thresholds indicated below: 

[***] 

  
 27 













 Pfizer will make any Sales Milestone Payment payable with respect to a Pfizer Year within [***] days after
the end of the applicable Pfizer Year, and such payment will be accompanied by a report identifying the Products, Net Sales of each Product (including breakdown of gross receipts and permitted deductions), and the amount payable to BioNTech under
this Section 3. 4. For the avoidance of doubt: (a) each of the Sales Milestone Payments set forth above will be payable one time only, regardless of the number of times the corresponding Total Annual Net Sales levels are achieved in any number
of Pfizer Years; and (b) if Total Annual Net Sales first reach multiple thresholds indicated above in the same Pfizer Year, all respective Sales Milestone Payments shall be payable with respect to that Pfizer Year and shall not be payable
again. 
 3.5. Royalty Payments. 

3.5.1. Royalties. Subject to the provisions of Section 3.5.3, Pfizer will pay BioNTech RNA royalties on a tiered
marginal royalty rate basis during the course of a Pfizer Year as set forth below (the “Marginal Royalty Rates”) based on the applicable royalty percentage calculated against the applicable proportion of the annual aggregate
Territory-wide Net Sales resulting from the sale of all Products in all countries in the Territory for which the applicable Royalty Term is in effect, during each Pfizer Year: 

[***] 
 Each Marginal Royalty Rate set forth in the table above
will apply only to that portion of the Net Sales of the Products in all countries in the Territory for which the applicable Royalty Term is in effect during a given Pfizer Year and that falls within the indicated range. An example calculation of
royalties under this Section 3.5.1 is set forth in Schedule 3.5.1. 
 3.5.2. Fully Paid-Up, Royalty Free License. Following expiration of the Royalty Term for any Product in a given country, no further royalties will be payable in respect of sales of such Product in such country and,
thereafter the licenses granted to Pfizer under Sections 2.1, 2.2, 2.3.1 and 2.7 with respect to such Product in such country will automatically become exclusive, fully paid-up, perpetual, irrevocable and
royalty-free. 
 3.5.3. Royalty Adjustments. The following adjustments will be made, on a Product-by-Product and country-by-country basis, to the royalties payable pursuant to
Section 3.5.1: 
 (a) Third Party Patents. If it is Necessary or Useful for Pfizer to license one or more Patent
Rights from one or more Third Parties in respect of the Development, Manufacture, Commercialization, Exploitation or use of any Product in any country, whether directly or through any Pfizer Affiliate or Sublicensee, then Pfizer may, in its
reasonable discretion, negotiate and obtain a license under such Patent Right(s) (each such Third Party license referred to herein as an “Additional Third Party License”). Any royalty otherwise payable to BioNTech under this
Agreement with respect to Net Sales of such Product in such country by Pfizer, its Affiliates or Sublicensees will be [***] For the avoidance of doubt, this Section 3.5.3(a) shall not apply to any direct licenses entered into


  
 28 













 
by Pfizer with a Current Licensor in accordance with Section 2. 8. 4. For the purposes of this Section 3.5.3(a): ( i) “Necessary” means that, without a license to use
the Patent Right in question, the Development, Manufacture, Commercialization or use of any Candidate or Product, in Pfizer’s opinion, infringes such Patent Right and (ii) “Useful” means that Pfizer has determined that such
Third Party’s Patent Right would reasonably enhance the potential, including by reducing cost or complexity of Manufacture, of such Licensed Product.

(b) No Adjustment for BioNTech Third Party Agreements. Subject to Section 2.9, BioNTech will be solely responsible for
(i) all obligations (including any royalty or other obligations that relate to the BioNTech Technology or BioNTech’s interest in the Research Program Technology) under its agreements with Third Parties that are in effect as of the
Effective Date or that BioNTech enters into during the Term and (ii) all payments to inventors (other than inventors that are Representatives of Pfizer) of BioNTech Technology or Research Program Technology, including payments under
inventorship compensation Laws, except that Pfizer will [***] (x) solely to the extent such royalties are due in connection with the sale of Candidates or Products hereunder and (y) provided that, notwithstanding anything in the Agreement to
the contrary, [***]. 
 (c) Expiry of Valid Claim Coverage. In the event that, with respect to any particular Product
in any particular country in the Territory, the Royalty Term for such Product in such country extends beyond the date on which such Product is not Covered by any Valid Claim in such country, Net Sales in any such country shall be reduced by [***]
for the remainder of the applicable Royalty Term, provided, however, that if this Section 3.5.3(c) applies to a Product, Pfizer may not also apply Section 3.5.3(e). 

(d) Existing Pfizer Third Party Agreements. Pfizer will be solely responsible for all obligations (including royalty
obligations) that relate to Products under its agreements with Third Parties that are in effect on or prior to the Effective Date. 

(e) Biosimilar Entry. Notwithstanding the foregoing, for any royalty otherwise payable to BioNTech under this Agreement
with respect to Net Sales based on sales of a Product in a given country in the Territory, any payments owed with respect to such Product in such country pursuant to this Section 3.5 [***]. 

(f) Royalty Floor. Notwithstanding the provisions of this Section 3.5.3, the maximum reduction of royalties [***].

 3.6. Reports and Payments. 

3.6.1. Cumulative Royalties. The obligation to pay royalties under this Agreement will be imposed only once with respect
to any sale of any Product. 
 3.6.2. Single Payee. All payments due and payable by Pfizer or its Affiliates or
sublicenses under this Section 3 shall be solely made to BioNTech RNA in full satisfaction of all consideration due hereunder in exchange for the rights granted by BioNTech. 

  
 29 













 3.6.3. Royalty Statements and Payments. Within [***] days of the end
of each Calendar Quarter, Pfizer will deliver to BioNTech a report setting forth, for the most recent Pfizer Quarter ending during such Calendar Quarter, the following information, on a
country-by-country and Territory-wide basis: [***]. No such reports will be due for any such Product (i) before the First Commercial Sale of such Product or
(ii) after the Royalty Term for such Product has expired in all countries in the Territory. The total royalty due for the sale of all such Products during such Pfizer Quarter will be remitted at the time such report is made; provided
that to the extent any royalties are payable by Pfizer hereunder on Net Sales of a Product in a country solely due to a Valid Claim Covering such Product in such country that is subject to a revocation, invalidity or unenforceability ruling that
is appealable or being appealed, during the time of such appeal or appealability, such royalties payable by Pfizer shall be placed into an escrow account and either (x) returned to Pfizer upon a final, unappealable determination that such
revocation, invalidity or unenforceability ruling is upheld or (y) released to BioNTech in the event such revocation, invalidity or unenforceability ruling is not upheld in a final, unappealable determination. In the event that BioNTech
disagrees with the basis of Pfizer’s calculations of royalties due because BioNTech believes that a Valid Claim Covering a Product was incorrectly omitted from Pfizer’s royalty calculations, BioNTech shall notify Pfizer within [***] days
of receipt of the relevant royalty statement. 
 3.6.4. Taxes and Withholding. 

(a) Withholding Taxes. The Parties agree to use commercially reasonable efforts to cooperate with one another and use
commercially reasonable efforts to avoid or reduce, to the extent permitted by applicable Law, tax withholding or similar obligations in respect of royalties, milestone payments, and other payments made by the paying Party to the receiving Party
under this Agreement (“Withholding Taxes”). If Withholding Taxes are imposed on any payment under this Agreement, the liability for such Withholding Taxes shall be the sole responsibility of the receiving Party, and the paying Party
shall (i) deduct or withhold such Withholding Taxes from the payment made to the receiving Party, (ii) timely pay such Withholding Taxes to the proper taxing authority, and (iii) send proof of payment to the receiving Party within
[***] days following such payment. Each Party shall comply with (or provide the other Party with) any certification, identification or other reporting requirements that may be reasonably necessary in order for the paying Party to not withhold
Withholding Taxes or to withhold Withholding Taxes at a reduced rate under an applicable bilateral income tax treaty. Each Party shall provide the other with commercially reasonable assistance to enable the recovery, as permitted by applicable Law,
of Withholding Taxes or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing the cost of such Withholding Taxes under this Section 3.6.4 (Taxes and Withholding).
Notwithstanding the foregoing, if as a result of any assignment or sublicense by the paying Party, any change in the paying Party’s tax residency, any change in the entity that originates the payment, or any failure on the part of the paying
Party to comply with applicable Law with respect to Withholding Taxes (including filing or record retention requirements), Withholding Taxes are imposed that would not otherwise have been imposed (“Incremental Withholding Taxes”),
then the paying Party shall be solely responsible for the amount of such Incremental Withholding Taxes and shall increase the amounts payable to the receiving Party so that the receiving Party receives a sum equal to the sum which it would have
received had there been no such imposition of Incremental Withholding Taxes. 

  
 30 













 (b) Value Added Tax. All payments between the Parties under this
Agreement are exclusive of applicable statutory value added tax or similar taxes (“VAT”), if any, which shall be listed separately on each invoice. If and to the extent any VAT will become payable due to any supplies or services
rendered under this Agreement and if and to the extent such VAT is to be paid by the Party providing the supply or service to the competent tax authorities, the receiving Party shall pay an amount equal to such VAT to the providing Party upon
receipt of a valid invoice allowing for the recovery of such VAT. 
 3.6.5. Currency, Source of Payments. All amounts
payable and calculations under this Agreement will be in United States dollars, and Pfizer agrees to make all payments from a source in the United States of America. As applicable, Net Sales and any royalty deductions will be translated into United
States dollars at the exchange rate used by Pfizer for public financial accounting purposes. If, due to restrictions or prohibitions imposed by national or international authority, a given payment cannot be made as provided in this
Section 3.6.5, the Parties will consult with a view to finding a prompt and acceptable solution. If the Parties are unable to identify a mutually acceptable solution regarding such payment, then Pfizer may elect, in its sole discretion, to
deliver such payment in the relevant jurisdiction and in the local currency of the relevant jurisdiction. 
 3.6.6. Method
of Payment. Except as permitted pursuant to Section 3.6.5, each payment hereunder will be made by electronic transfer in immediately available funds via either a bank wire transfer, an ACH (automated clearing house) mechanism, or any other
means of electronic funds transfer, at Pfizer’s election, to such bank account set forth below or as BioNTech RNA will designate in writing to Pfizer at least [***] days before the payment is due. All invoice or billing related questions should
be referred to Pfizer’s Accounting Department at 800.601.1357 or go to the Accounts Payable Invoice Portal at ap.pfizer.com. 

[***] 

3.6.7. Record Keeping. Pfizer will keep and will cause its Affiliates and use Commercially Reasonable Efforts to cause
its Sublicensees to keep books and accounts of record in connection with the sale of Products in sufficient detail to permit accurate determination of all figures necessary for verification of royalties and Sales Milestone Payments to be paid
hereunder. Pfizer and its Affiliates will maintain, and Pfizer shall use Commercially Reasonable Efforts to cause its Sublicensees to maintain, such records for a period of at least [***] years, or such longer period of time required under a Current
License, insofar as applicable to the rights sub-licensed pursuant to such Current License and used by Pfizer, its Affiliates and Sublicensees, after the end of the Pfizer Quarter in which they were generated.

 3.6.8. Audits. Upon [***] days prior notice from BioNTech, Pfizer will permit (and shall use Commercially
Reasonable Efforts to cause its Sublicensees to permit) an independent certified public accounting firm of nationally recognized standing selected by BioNTech and reasonably acceptable to Pfizer, to examine, at BioNTech’s sole expense, the
relevant books and records of Pfizer and its Affiliates (and where possible, its Sublicensees) as may be reasonably necessary to verify the amounts reported by Pfizer in accordance with Section 3.6.3 and the payment of royalties and Sales
Milestone Payments hereunder. An examination by BioNTech under this Section 3.6.8 will occur not more than once in any Calendar Year and will be limited to the pertinent books and records for any Calendar Year ending not more than [***] years
before the date of the request. The 

  
 31 













 
accounting firm will be provided access to such books and records at Pfizer’s or its Affiliates’ (or where possible its Sublicensees’) facility(ies) where such books and records
are normally kept and such examination will be conducted during Pfizer’s or its Affiliates’ (or, where possible, its Sublicencees’) normal business hours. Pfizer may require the accounting firm to sign a reasonably acceptable non-disclosure agreement before providing the accounting firm with access to Pfizer’s or its Affiliates’ (or where possible its Sublicensees’) facilities or records. Upon completion of the audit, the
accounting firm will provide both Pfizer and BioNTech the same written report disclosing any discrepancies in the reports submitted by Pfizer or the royalties or Sales Milestone Payments paid by Pfizer, and, in each case, the specific details
concerning any discrepancies. No other information will be provided to BioNTech. Where Pfizer is not able to cause its Sublicensees to permit an audit according to this Section 3.6.8 (despite using Commercially Reasonable Efforts), Pfizer shall on
BioNTech’s request exercise its own audit rights under the relevant sublicense agreement; provided, however, that (a) BioNTech shall not request such audit exercise more than once in a Calendar Year, (b) the audit shall be limited
to the pertinent books and records for any Calendar Year ending not more than [***] years before the date of the request and (c) if the amount of any underpayment of royalties by any such Sublicensee is less than [***] of the royalties properly
payable to BioNTech, then BioNTech shall reimburse Pfizer for Pfizer’s out-of-pocket costs in connection with the audit. 

3.6.9. Underpayments/Overpayments. If such accounting firm concludes that additional royalties or Sales Milestone
Payments were due to BioNTech, then Pfizer will pay to BioNTech the additional royalties or Sales Milestone Payments within [***] days of the date Pfizer receives such accountant’s written report. Further, if the amount of such underpayments
exceeds more than [***] of the amount that was properly payable to BioNTech, then Pfizer will reimburse BioNTech for BioNTech’s out-of-pocket costs in connection
with the audit. If such accounting firm concludes that Pfizer overpaid royalties or Sales Milestone Payments to BioNTech, then BioNTech will refund such overpayments to Pfizer, within [***] days of the date BioNTech receives such accountant’s
report. 
 3.6.10. Confidentiality. Notwithstanding any provision of this Agreement to the contrary, all reports and
financial information of Pfizer, its Affiliates or its Sublicensees which are provided to or subject to review by BioNTech will be deemed to be Pfizer’s Confidential Information and subject to the provisions of Section 8. 

3.7. No Guarantee of Success. 

3.7.1. Pfizer and BioNTech acknowledge and agree that payments to BioNTech pursuant to Section 3.3, Section 3.4 and
Section 3.5: (a) have been included in this Agreement on the basis that they are only payable or otherwise relevant if a certain Product is successfully Developed or Commercialized in such country, as applicable; (b) are solely intended to
allocate amounts that may be achieved upon successful Development or Commercialization of such Product as applicable, between Pfizer (who will receive all Product sales revenues) and BioNTech; (c) are not intended to be used as a measure of
damages if this Agreement is terminated for any reason, including pursuant to Pfizer’s right to terminate for convenience, before any such success is achieved and such amounts become due; and (d) will only be triggered, and will only be
relevant as provided, in accordance with the terms and conditions of such provisions. 

  
 32 













 3.7.2. Pfizer and BioNTech further acknowledge and agree that nothing in
this Agreement, or in any document or presentation provided by Pfizer to BioNTech prior to the Effective Date will be construed as representing any estimate or projection of (i) the successful Development or Commercialization of any Product
under this Agreement, (ii) the number of Products that will or may be successfully Developed or Commercialized under this Agreement, (iii) anticipated sales or the actual value of any Products that may be successfully Developed or
Commercialized under this Agreement or (iv) the damages, if any, that may be payable if this Agreement is terminated for any reason. 

3.7.3. Pfizer makes no representation, warranty or covenant, either express or implied, that (A) it will successfully
Develop, Manufacture, Commercialize or continue to Develop, Manufacture or Commercialize any Product in any country, (B) if Commercialized, that any Product will achieve any particular sales level, whether in any individual country or
cumulatively throughout the Territory or (C) Pfizer will devote, or cause to be devoted, any level of diligence or resources to Developing or Commercializing any Product in any country, or in the Territory in general, other than is expressly
required under Section 6.2.

 (e) Decision-making. Notwithstanding the number of Pfizer JSC Members or BioNTech JSC Members, each Party will have
one (1) vote, and the JSC will make decisions on a unanimous basis. The JSC will use good faith efforts to reach agreement on any and all matters properly brought before it. If, despite such good faith efforts, the JSC is unable to reach
unanimous agreement on a particular matter, within [***] days after the JSC first meets to consider such matter, or such later date as may be mutually acceptable to the Parties (each such matter, a “Disputed Matter”), then either
Party may refer that Disputed Matter for resolution by the appropriate senior officer of each Party, and such senior officers will promptly initiate discussions in good faith to resolve such Disputed Matter. If the senior officers of each Party are
unable to resolve the Disputed Matter within [***] days of it being referred to them, then Pfizer will have final decision-making authority with respect to all Disputed Matters, subject only to specific issues identified in this Agreement as
expressly requiring mutual consent or unanimous vote of the Parties. 
 (f) Limits on JSC Authority. Notwithstanding
any provision of this Section 4.3 to the contrary, (i) each Party will retain the rights, powers and discretion granted to it under this Agreement and no such rights, powers, or discretion will be delegated to or vested in the JSC unless

	5.	 MANUFACTURING AND SUPPLY 



5.1. Development of Manufacture Process. Beginning on the Effective Date of the Agreement and throughout the Research Term (including
any extension pursuant to Section 4.4), BioNTech and Pfizer shall jointly Develop a scalable process for Manufacture of Candidates and Products in the Field. Should Pfizer request any assistance from BioNTech to Develop (or continue to Develop)
a scalable process for Manufacture of the Candidates and Products in the Field after the Research Term (including any extension pursuant to Section 4.4), BioNTech shall provide such assistance after such Research Term at an hourly rate of [***]
for its support and efforts in connection with such Development. Such payments shall be governed by the terms of Section 3.6 and BioNTech shall be required to keep, and provide to Pfizer, detailed reports and timesheets for those personnel
involved. 
 5.2. Manufacture of CTM for FIH Study. BioNTech shall Manufacture, at its cost, all CTM for the Candidates or Products
that are the subject of the FIH Study described in the Research Plan. 
 5.3. Supply of CTM to Pfizer. BioNTech shall supply Pfizer
with CTM for the Products it studies in any Phase I Clinical Trial and Phase II Clinical Trial. Without prejudice to that obligation, the Parties shall negotiate in good faith and acting reasonably a mutually agreed upon Quality Agreement and Supply
Agreement which shall be executed on or before [***]; such Supply Agreement shall be consistent with the heads of terms set forth in Schedule 5.3. Pfizer’s schedule for Clinical Trials would take into account the Manufacturing capacity
available at BioNTech and the Parties would agree on a [***] month Manufacturing capacity plan for Clinical Trial batches no later than [***] months in advance of any delivery date for such batch. If Pfizer so requests during the term of such Supply
Agreement, Pfizer and BioNTech shall discuss an extension of such Supply Agreement at an appropriate time and negotiate in good faith if Pfizer requires a bridge to Pfizer for CTM for Pfizer’s Phase III Clinical Trials or for Pfizer’s
commercial supply. 
 5.4. Technology Transfer of Manufacturing Process. BioNTech will provide Pfizer with all reasonable assistance
necessary or useful to effect the timely and orderly transfer of the process for Manufacturing Products in the Field to enable Pfizer or Pfizer’s named contract manufacturing organization (“CMO”) to successfully Manufacture
such Products on Pfizer’s behalf. Without limiting BioNTech’s obligations set forth elsewhere under this Agreement, the Parties will use their Commercially Reasonable Efforts to perform all technology transfer activities as set forth under
the initial Manufacturing technology 

  
 39 













 
transfer plan set forth in Exhibit D (the “Manufacturing Technology Transfer Plan”). BioNTech will cause all technology transfer activities to be performed under the
Manufacturing Technology Transfer Plan to be carried out by the specific individuals identified to perform such activities in the Manufacturing Technology Transfer Plan (if any) and otherwise by appropriately skilled and experienced individuals
familiar with the Manufacture of such Products. Such Manufacturing Technology Transfer Plan will be updated by the JSC no later than [***] months after the Effective Date. In case of a technology transfer to a CMO, technology transfer shall only be
initiated if and when: (a) such CMO has entered into confidentiality undertakings in respect of BioNTech Technology, Research Program Technology and Confidential Information of BioNTech or its Representatives on customary terms comparable to
and no less restrictive than those that bind the Parties under this Agreement either (i) directly with BioNTech or (ii) with Pfizer but including BioNTech as third party beneficiary, and (b) BioNTech has been provided with a copy of
such confidentiality undertakings. For clarity, such CMO would not have the right to use any BioNTech Technology, Research Program Technology or Confidential Information of BioNTech or its Representatives licensed to and transferred to Pfizer or the
CMO for any purpose other than the Manufacture of Products in the Field on Pfizer’s behalf. 
 5.5. Transfer Activities and
Consulting Support. In addition to the support provided under the Manufacturing Technology Transfer Plan and the Product Technology Transfer Plan,BioNTech will provide Pfizer with up to [***] hours of FTE support reasonably requested by Pfizer

required to keep, and provide to Pfizer, detailed reports and timesheets for those personnel involved. Any Intellectual Property Rights generated pursuant to services under this Section shall be deemed work product from a work for hire arrangement
and shall be owned by Pfizer. 
  

	6.	 PRODUCT DEVELOPMENT AND COMMERCIALIZATION 



6.1. General. Subject to the provisions of Sections 4.2, 4.3, 5.2, 5.3 and 6.2, Pfizer will have sole authority over and control of the
Development, Manufacture, Regulatory Approval and Commercialization of Candidates and Products and will retain final decision-making authority with respect thereto. 

6.2. Diligence. 

6.2.1. Development Diligence. Pfizer will use its Commercially Reasonable Efforts to Develop and seek Regulatory
Approval for one Product in the Field in [***]. Pfizer will have no other diligence obligations with respect to the Development or Regulatory Approval of Products under this Agreement. 

6.2.2. Commercial Diligence. Pfizer will use its Commercially Reasonable Efforts to Commercialize a given Product in the
Field in each Major Market Country in the Territory where Pfizer or its designated Affiliates or Sublicensees has received Regulatory Approval for such Product. Pfizer will have no other diligence obligations with respect to the Commercialization of
Products under this Agreement. 

  
 40 













 6.2.3. Exceptions to Diligence Obligations. Notwithstanding any
provision of this Agreement to the contrary, Pfizer will be relieved from and will have no obligation to undertake any efforts with respect to any diligence obligation under Section 6.2.1 or Section 6.2.2 with respect to a given Candidate
or Product in the event that: 
 (a) Pfizer or BioNTech receives or generates any safety, tolerability or other data
reasonably indicating or signaling, as measured by Pfizer’s safety and efficacy evaluation criteria and methodology, that such Candidate or Product has or would have an unacceptable risk-benefit profile or is otherwise not reasonably suitable
for initiation or continuation of Clinical Trials; 
 (b) Pfizer or BioNTech receive any notice, information or
correspondence from any applicable Regulatory Authority, or any applicable Regulatory Authority takes any action, that reasonably indicates that such Candidate or Product is unlikely to receive Regulatory Approval; or 

(c) that BioNTech fails to fulfill its Development or other obligations under the Research Plan or this Agreement and such
failure prevents Pfizer from fulfilling the Pfizer Diligence Obligations. 
 For the avoidance of doubt, the Pfizer Diligence Obligations in
respect of Candidates and Products not affected by the circumstances described in this Section 6.2.3 shall continue to apply. 

6.2.4. Deemed Satisfaction of Pfizer Diligence Obligations. Without in any way expanding Pfizer’s obligations under
this Agreement: 
 (a) Pfizer’s achievement of any Development Event entitling BioNTech to receive a specific
Development Payment described in Section 3.3 will be conclusive evidence that Pfizer has satisfied all Pfizer Diligence Obligations under this Agreement up to the date that such Development Event is achieved; 

(b) on a Major Market Country-by-Major Market
Country basis, Pfizer’s payment, and BioNTech’s acceptance, of any royalties to BioNTech pursuant to Section 3.5 with respect to Net Sales in such Major Market Country will be conclusive evidence that Pfizer has satisfied all Pfizer
Diligence Obligations under this Agreement in respect of such Major Market Country to the date of such payment; provided that if BioNTech does not return in full a payment of royalties by Pfizer with a written rejection of such payment within
ten days of receipt, BioNTech shall be deemed to have accepted such royalty payment; and 
 (c) Pfizer’s payment of any
Sales Milestone Payment as set forth in Section 3.4 will be conclusive evidence that Pfizer has satisfied all Pfizer Diligence Obligations under this Agreement to the date of such payment. 

For the avoidance of doubt, the provisions of Sections 6.2.4(a) through 6.2.4(c) are intended only as examples of diligence constituting
satisfaction of the Pfizer Diligence Obligations.Pfizer may fully satisfy the Pfizer Diligence Obligations without achieving any of the specific diligence examples set forth in Sections 6.2.4(a) through 6.2.4(c) above, provided that Pfizer
otherwise complies with the provisions of Section 6.2.1 or Section 6.2.2, as applicable. 

  
 41 













 6.2.5. Assertion of Pfizer Diligence Obligation Claims. If BioNTech
is or becomes aware of facts that might form a reasonable basis to allege that Pfizer has failed to meet any Pfizer Diligence Obligation, then BioNTech will promptly notify Pfizer in writing of such potential alleged performance failure (each such
potential alleged performance failure, a “Diligence Issue”). Promptly upon Pfizer’s receipt of any notice of a Diligence Issue pursuant to this Section 6.2.5, the Pfizer Program Director will contact the BioNTech Program
Director to discuss the specific nature of such Diligence Issue and seek to identify an appropriate corrective course of action. If, no later than [***] days after Pfizer’s receipt of such a notice, (a) the Parties have not reached
consensus regarding whether Pfizer has failed to satisfy its obligations pursuant to Section 6.2.1 or Section 6.2.2 and (b) the Parties’ respective Program Directors have not agreed upon an appropriate corrective course of action
for such Diligence Issue, then such Diligence Issue will be escalated and resolved pursuant to the dispute resolution provisions set forth in Section 12.12. If BioNTech fails to notify Pfizer of a Diligence Issue pursuant to this Section 6.2.5
within [***] days after the date on which BioNTech first discovers such Diligence Issue, then Pfizer will be deemed to have satisfied its Diligence Obligations with respect to such Diligence Issue. 

6.2.6. Remedies for Breach of Pfizer Diligence Obligations. If Pfizer materially breaches any Pfizer Diligence
Obligation and fails to remedy such breach within [***] days of Pfizer’s receipt of notice of such breach from BioNTech, then BioNTech may, in its sole discretion, elect to either: (a) terminate this Agreement pursuant to the provisions of
Section 10.5, but only to the extent that a Product in a given Major Market Country in the Territory is directly and adversely impacted by such uncured material breach (and for the avoidance of doubt, the [***] day period set forth in this
Section 6.2.6, shall be deemed the same [***] day cure period set out pursuant to Section 10.5); or (b) convert any exclusive license or sublicense granted to Pfizer under this Agreement with respect to a Product in a given Major Market
Country in the Territory where such breach occurred and remains unremedied into a non-exclusive license or sublicense, as applicable, but only to the extent that such Product in such Major Market Country is
directly and adversely impacted by such uncured material breach. BioNTech acknowledges and agrees that the elections set forth in this Section 6.2.6: (i) have been negotiated by the Parties to fully address any harm that BioNTech may incur as a
result of Pfizer’s material breach of the Pfizer Diligence Obligations and (ii) constitute BioNTech’s sole and exclusive remedies with respect to any breach by Pfizer of any Pfizer Diligence Obligation. 

6.2.7. Performance by Pfizer’s Affiliates or Sublicensees. For avoidance of doubt, any actions taken by
Pfizer’s Affiliates or Sublicensees (or their respective subcontractors) under this Agreement shall be treated as actions taken by Pfizer in regard to satisfaction of the requirements of this Section 6.2. 

6.3. Regulatory Matters. 

6.3.1. Regulatory Reporting. Pfizer or its designated Affiliate(s) will have the sole authority to make or file all
filings, reports and communications with all Regulatory Authorities with respect to any Candidate or Product in the Field in the Territory, including all reports required to be filed in order to obtain or maintain any Regulatory Approvals granted
for Products in the Field in the Territory and adverse drug experience reports with the exception of the FIH Study, which will be managed and sponsored by BioNTech. Upon Pfizer’s request, BioNTech will provide to Pfizer the data arising from
the FIH Study, as well as any data or other information in BioNTech’s possession or Control reasonably necessary or useful to support its filings, reports or communications with Regulatory Authorities and otherwise provide reasonable assistance
to Pfizer in connection with any such filings, reports and communications with Regulatory Authorities. 

  
 42 













 6.3.2. Regulatory Approvals. Pfizer or its designated Affiliate(s)
will have the sole authority to prepare and file applications, in its own name, for Regulatory Approval for Candidates or Products in the Field in the Territory, including communicating with any Regulatory Authority both prior to and following
Regulatory Approval. BioNTech hereby assigns any and all INDs, Regulatory Approvals or any other rights or permissions granted by any Regulatory Authority to Pfizer, together with all other regulatory filings and development data, to the extent such
assignment is permissible under applicable Law and requested by Pfizer. Further, BioNTech will take all actions and provide all assistance reasonably requested by Pfizer to effect the assignments in this Section 6.3.2. 

6.3.3. Cooperation. If reasonably requested by Pfizer, BioNTech shall assist and cooperate with Pfizer in connection
with the preparation of filings, reports and communications to Regulatory Authorities with respect to any Candidate or Product in the Field in the Territory, at Pfizer’s sole expense. BioNTech will and will cause its Affiliates to cooperate
with Pfizer and all Pfizer Representatives in the event of any inspection by a Regulatory Authority related to any Candidate or Product or any activities to be performed under this Agreement. 

6.4. Commercialization Activities. 

6.4.1. General. Subject to Section 6.2, Pfizer will have sole and exclusive control over all matters relating to the

Sublicensees will select and own all Trademarks and Copyrights used in connection with the Commercialization of any and all Products in the Field in the Territory. Neither BioNTech nor its Affiliates will use or seek to register, anywhere in the
world, any Trademark which is confusingly similar to any Trademark used by or on behalf of Pfizer, its Affiliates or Sublicensees in connection with any Product. [***]. 

6.5. Manufacturing. With respect to Candidates or Products to be Commercialized in the Field in the Territory and except to the extent
BioNTech has Manufacturing obligations under the Research Plan or as described in Section 5, Pfizer will have the exclusive right to Manufacture such Candidates or Products itself or through one or more Affiliates or Third Parties selected by
Pfizer in its sole discretion. For clarity, Pfizer will have no diligence obligations with respect to the Manufacture of Products except to the extent necessary to fulfill its obligations under Section 6.2.1 or Section 6.2.2. 

6.6. Progress Reporting. After the first to occur of expiration of the Research Term or dissolution of the JSC and expiring on the
First Commercial Sale of a Product, Pfizer will provide BioNTech with annual written reports summarizing Pfizer’s activities to Develop and Commercialize Products in the preceding year. Any information or written report provided by Pfizer to
BioNTech pursuant to this Section 6.6 will be deemed to be Pfizer’s Confidential Information and subject to the provisions of Section 7.1. 

  
 43 













 6.7. Other Pfizer Programs. Subject to Pfizer’s exclusivity obligations
set forth in Section 2.10.3, BioNTech understands and acknowledges that Pfizer may have present or future initiatives or opportunities, including initiatives or opportunities with its Affiliates or Third Parties, involving products, programs,
technologies or processes that are similar to, and in some instances may compete with, a Candidate or Product, program, technology or process covered by this Agreement. BioNTech acknowledges and agrees that nothing in this Agreement will be
construed as a representation, warranty, covenant or inference that Pfizer will not itself Develop, Manufacture or Commercialize or enter into business relationships with one or more of its Affiliates or Third Parties to Develop, Manufacture or
Commercialize products, programs, technologies or processes that are similar to or that may compete with any Candidate or Product, program, technology or process covered by this Agreement, provided that, for clarity, Pfizer will not use

any such notice, if BioNTech elects to file or continue such prosecution or maintenance at BioNTech’s sole expense, (x) BioNTech shall be entitled to do so and take all steps in such prosecution and maintenance at its sole discretion;
(y) Pfizer will reasonably cooperate to promptly transfer the necessary files and execute the necessary forms regarding such transfer and (z) BioNTech will keep Pfizer advised on the status of such filing, prosecution and maintenance and
will reasonably consider any comments made by Pfizer in connection therewith. If BioNTech elects not to file or continue such prosecution or maintenance, then Pfizer may immediately abandon, allow to lapse, or omit to prosecute such Patent Right, as
the case may be. 
 (ii) Other Patent Rights. Except as provided in Sections 7.3.1(a), 7.3.1(b)(i) and 7.3.1(c),
Pfizer will have the sole right, but not the obligation, to file, prosecute and maintain the Product Patent Rights, the Research Program Patent Rights, the Pfizer Patent Rights (including RNA Improvements) and Patent Rights that it owns or to which
it otherwise has control of prosecution rights in its sole discretion. At BioNTech’s reasonable request, Pfizer will provide to BioNTech status information for any Research Program Patent Right in any Key Patent Jurisdiction and will consider
in good faith any recommendations made by BioNTech in regard to the filing, prosecution or maintenance of any such Patent Right. 

  
 47 













 (iii) Reference of Research Program
Know-how. If Pfizer chooses to file, and thereafter prosecute and maintain, Patent Rights after the expiration of the Research Term, including any extension to the Research Term under Section 4.4,
Pfizer may use or incorporate Research Program Know-How in the filing or prosecution of such Patent Rights filed after the Research Term, if Pfizer determines in its sole discretion that it is necessary or
useful to use or incorporate such Research Program Know-How. 
 (c) Joint Patent
Rights. In the event the Parties make any Joint Know-How, the Parties will promptly meet to discuss and determine, based on mutual consent, whether to seek patent protection thereon. Neither Party will
file any Joint Patent Right without mutual consent. Unless otherwise agreed between the Parties, if the Parties decide to seek patent protection for any Joint Know-How: (i) BioNTech will have the first
right, but not the obligation, to prepare, file, prosecute and maintain any Joint Patent Right predominantly relating to the RNA Technology or RNA Process Technology throughout the world, and (ii)Pfizer will have the first right, but not the
obligation, to prepare, file, prosecute and maintain any other Joint Patent Right throughout the world, in each case of (i) and (ii) with the respective provisions of Section 7.3.1(a) or 7.3.1(b)(i) to apply mutatis mutandis except
as provided in this Section 7.3.1(c). The non-filing Party will reimburse the filing Party for 50% of the costs reasonably incurred by the filing Party in preparing, filing, prosecuting and maintaining
such Joint Patent Rights, which reimbursement will be made pursuant to, and within 75 days of, invoices (including supporting documentation) submitted by the filing Party to the non-filing Party no more often
than once per Calendar Quarter. The non-prosecuting Party will cooperate with the prosecuting Party in taking reasonable measures to control costs and non-prosecuting
Party shall be responsible for 100% of (x) any fees or costs related to any correspondence of outside counsel with or instructions to outside counsel by such Party (or any of such Party’s Representatives) which is independent of joint
prosecution efforts, or (y) any patent office fees, and associated counsel/agent fees and costs, for extensions which are not incurred at the request of, and not due to the actions of, the prosecuting Party. If, once the Parties have agreed to
prepare and file an application of Joint Patent Rights, either Party (the “Declining Party”) at any time thereafter declines to participate in the preparation, filing, prosecution or maintenance of any Joint Patent Right or share in
the costs of filing, prosecuting and maintaining any Joint Patent Right, on a country-by-country basis, the Declining Party will provide the other Party (the
“Continuing Party”) with 30 days prior written notice to such effect, in which event, the Declining Party will (A) have no responsibility with respect to the filing, prosecution or maintenance of the applicable Joint Patent
Right after the end of such 30 day period, (B) have no responsibility for any expenses incurred in connection with such Joint Patent Right after the end of such 30 day period and (C) if the Continuing Party elects to continue filing,
prosecution or maintenance, the Declining Party, upon the Continuing Party’s request, will execute such documents and perform such acts, at the Continuing Party’s expense, as may be reasonably necessary (1) to assign to the Continuing
Party all of the Declining Party’s right, title and interest in and to such Joint Patent Right and (2) to permit the Continuing Party to file, prosecute and maintain such Joint Patent Right at its


  
 48 













 
sole expense. Where such Joint Patent Right is assigned to Pfizer as the Continuing Party, BioNTech will retain a non-exclusive, sublicensable, perpetual,
irrevocable, royalty-free, fully paid-up worldwide right and license to practice and exploit such Patent Right for any and all purposes excluding, during the Term, in the Field in the Territory; and where such
Joint Patent Right is assigned to BioNTech as the Continuing Party, it will be excluded from the definition of BioNTech Patent Rights, and Pfizer will retain a non-exclusive, sublicensable, perpetual,
irrevocable, royalty-free, fully paid-up worldwide right and license to practice and exploit such Joint Patent Right for any and all purposes. 

(d) Prosecution by Third Party Licensors. Except in the ordinary course of filing continuation applications, BioNTech
shall not decline to pay for or participate in the filing, prosecution or maintenance of any Patent Right under any BioNTech Third Party Agreement in any Key Patent Jurisdiction (or other country to the extent doing so may result in BioNTech’s
loss of license to such Patent Right in such country), to the extent BioNTech is obligated to pay for, or has the right to participate in, such filing, prosecution or maintenance, that is included in the BioNTech Patent Rights and that, in
Pfizer’s reasonable opinion, covers any Candidate, Product [***] in the Field, and the loss of which would result in loss of right to or would materially diminish the overall protection of such Candidate or Product, without Pfizer’s prior
written consent, not to be unreasonably withheld or delayed. 
 (e) Patent Term Restoration and Extension. Upon
the request of either Party, the Parties will (through the Patent Committee) reasonably discuss patent term extension and supplemental protection certificate strategies in relation to Patent Rights Covering Candidates or Products at any time.
Notwithstanding the above, within the time period specified by applicable Law upon receiving Regulatory Approval for a Product in any country in the Territory, Pfizer will have the right, but not the obligation, exercisable through written notice to
BioNTech, to seek, in BioNTech’s name, if so required, patent term extensions, and supplemental protection certificates and the like available under Law, including 35 U.S.C. § 156 and applicable foreign counterparts (the “Patent
Term Extension”), in such country in the Territory in relation to (i) any Research Program Patent Right other than Patent Rights claiming BioNTech Improvements and (ii) any BioNTech Prosecution Patent Right which is still eligible
for Patent Term Extension at that time under the applicable Law in such country, in each case of (i) and (ii) that Cover such Product. If Pfizer exercises such right, BioNTech and Pfizer will cooperate in connection with all such activities at
Pfizer’s expense. Pfizer, its agents and attorneys will give due consideration to all suggestions and comments of BioNTech regarding any such activities, but, in the event of a disagreement between the Parties in relation to a Patent Term
Extension for a BioNTech Prosecution Patent Right or Research Program Patent Right, Pfizer will have the final decision-making authority. For the avoidance of doubt, nothing in this Section 7.3.1(e) shall prevent BioNTech from seeking, or
allowing any other collaboration partner of BioNTech to seek, any Patent Term Extension in relation to any BioNTech Prosecution Patent Right prior to Pfizer exercising its rights under this Section 7.3.1(e). Notwithstanding the foregoing,
BioNTech shall not seek any Patent Term Extension in relation to any Patent Right with respect to any Product or Candidate without Pfizer’s prior written consent. 

  
 49 













 (f) Clarifications. For clarity, prosecution under this
Section 7.3.1 includes opposition, revocation and post-grant review proceedings before the granting patent office or other patent office proceedings (“Prosecution Proceeding”). If such Prosecution Proceedings are concurrent
with Third Party litigation under Section 7.3.2 and are applicable to or part of a coordinated enforcement of such rights, the prosecuting Party and the enforcing Party shall work together and closely align their prosecution and enforcement
strategy in accordance with Section 7.3.3 (including the right for one Party to have final control as stipulated in Section 7.3.3). 

(g) Liability. To the extent that a Party is obtaining, prosecuting or maintaining a Patent Right or otherwise
exercising its rights under this Section 7.3.1, such Party, and its Affiliates, employees, agents or representatives, will not be liable to the other Party in respect of any act, omission, default or neglect on the part of any such Party, or
its Affiliates, employees, agents or representatives, in connection with such activities undertaken in good faith. 
 (h)
Recording. If either Party deems it necessary or useful to register or record this Agreement or evidence of this Agreement with any patent office or other appropriate Governmental Authority(ies) in one or more jurisdictions in the Territory,
the other Party will reasonably cooperate to execute and deliver to such Party any documents accurately reflecting or evidencing this Agreement that are necessary or useful, in such Party’s reasonable judgment, to complete such registration or
recordation. 
 (i) Joint Research Agreement. This Agreement shall be understood to be a joint research agreement
under 35 U.S.C. § 103(c)(3) for pre-AIA Patent Rights and 35 U.S.C. § 100(h) for post-AIA Patent Rights entered into for the purpose of researching,
identifying and Developing Candidates and Products. 
 7.3.2. Enforcement of Patent Rights. 

(a) Notification of Infringement and Decision about Enforcement Actions. Each Party will promptly notify the other
(through the Patent Committee) in the event of any actual, potential or suspected infringement of a patent under the BioNTech Patent Rights or Research Program Patent Rights by any Third Party. In the event of any such notification, the Parties will
(through the Patent Committee) discuss in good faith the relevant actual, potential and suspected infringement and the risks and chances of success as well as chances of settlement connected with the institution of any litigation or other step to
remedy infringement (any such steps, or threat of or assertion or enforcement of a Patent Right being an “Enforcement Action”) taking into account the possible uses of the relevant Patent Rights by each Party, its respective
Affiliates or its or their licensees and the revenues relating to or impacted by such Patent Rights, with the goal to agree on whether or not any Enforcement Action should be taken and, if yes, to closely coordinate so far as reasonably possible
their respective efforts and strategies. The Parties acknowledge that time shall be of the essence in connection with any Enforcement Action and each shall move urgently and expeditiously to discuss and seek agreement on any actual or proposed
Enforcement Action. 

  
 50 













 (b) Enforcement of Core BioNTech Patent Rights. Subject to
Section 7.3.2(a), and unless otherwise agreed between the Parties on a case-by-case basis, as between Pfizer and BioNTech, BioNTech shall have the first right, but
not the obligation, to institute any Enforcement Action in connection with the Core BioNTech Patent Rights in the Field, and any such Enforcement Action will be at BioNTech’s expense including BioNTech indemnifying and holding harmless Pfizer
and its Affiliates from and against any adverse cost award, where Pfizer or its Affiliates join any such Enforcement Action upon BioNTech’s request or where required by Law. BioNTech will not, without the prior written consent of Pfizer, enter
into any compromise or settlement relating to such litigation that (i) admits the invalidity or unenforceability of any Core BioNTech Patent Right or (ii) requires BioNTech to abandon any Core BioNTech Patent Right. Pfizer, upon request of
BioNTech, agrees to timely commence or to join in any such Enforcement Action, at BioNTech’s expense, and in any event to cooperate with BioNTech in such Enforcement Action at BioNTech’s expense. Pfizer will have the right to consult with,
and provide comments to, BioNTech about such Enforcement Action and to participate in and be represented by independent counsel in such Enforcement Action at Pfizer’s own expense, and BioNTech shall take into account any reasonable comments
provided by Pfizer in such Enforcement Action. Neither Party will incur any liability to the other Party (other than that related to a Party’s indemnification obligation pursuant to Section 11) as a consequence of any Enforcement Action
initiated or pursued pursuant to this Section 7.3.2(b)or any unfavorable decision resulting therefrom, including any decision holding any Core BioNTech Patent Right invalid or unenforceable. Any infringement recoveries resulting from such
litigation or steps relating to a claim of Third Party infringement, after deducting BioNTech’s out of pocket expenses (including counsel fees and expenses including any adverse cost award) in pursuing such claim, will be for Pfizer’s sole
account and be deemed Net Sales on which Pfizer will pay royalties. 
 In respect of an infringement of a BioNTech Core Patent Right in the
Field in connection with a Competitive Product in a Major Market Country (“Competitive Product Infringement”), if, following (i) discussion of any potential Enforcement Action pursuant to Section 7.3.2(a) and (ii) a
subsequent written request by Pfizer to initiate any Enforcement Action in connection with such Competitive Product Infringement, BioNTech does not initiate any Enforcement Action in connection with such Competitive Product Infringement within
thirty (30) days following receipt of such notices, or as soon as possible and in any event no later than ten (10) Business Days if preliminary injunction proceedings are a potential or likely recourse to remedy the infringement), or ten
(10) days before the time limit, if any, set forth in the applicable Laws for the filing of such actions, Pfizer shall have the right, but not the obligation, in place of BioNTech to institute any Enforcement Action in connection with such
Competitive Product Infringement (including Enforcement Actions in countries in which the Manufacturing of the Competitive Product (or part thereof) reasonably believed to be designated for Major Market Countries takes place as well as Enforcement
Actions in Belgium, Ireland or the Netherlands that are in parallel with Enforcement Actions in any of the Major EU Market Countries), and any such Enforcement Action will be at Pfizer’s expense and the provisions set forth in the first
paragraph of this Section 7.3.2(b) shall apply mutatis mutandis, provided that any infringement recoveries resulting from such litigation or steps relating to a claim of Third Party infringement, after deducting Pfizer’s out
of pocket expenses (including counsel fees and expenses including any adverse cost award) in pursuing such claim, shall be for Pfizer’s sole account and be deemed Net Sales on which Pfizer will pay royalties. 

  
 51 













 (c) Pfizer Enforcement in the Field. Subject to Section 7.3.2(
a) and unless otherwise agreed between the Parties on a case-by-case basis, as between Pfizer and BioNTech, Pfizer shall have the sole right, but not the obligation, to
institute any Enforcement Action in the Territory in connection with any BioNTech Patent Right (other than Core BioNTech Patent Rights or those solely owned by Third Parties and licensed pursuant to a Current Licence to the extent BioNTech has no
enforcement rights in the Field in respect of the same) or Research Program Patent Rights in the Field, and any such Enforcement Action will be at Pfizer’s expense including Pfizer indemnifying and holding harmless BioNTech and its Affiliates
from and against any adverse cost award, where BioNTech or its Affiliates join any such Enforcement Action upon Pfizer’s request or where required by Law, subject to BioNTech’s obligation to indemnify Pfizer for such expenses pursuant to
Section 11; provided that any infringement recoveries resulting from such litigation or steps relating to a claim of Third Party infringement, after deducting Pfizer’s out of pocket expenses (including counsel fees and expenses
including any adverse cost award) in pursuing such claim, will be deemed Net Sales. Pfizer will not, without the prior written consent of BioNTech, enter into any compromise or settlement relating to such Enforcement Action that (i) admits the
invalidity or unenforceability of any BioNTech Patent Right or Research Program Patent Right or (ii) requires Pfizer or BioNTech to abandon any BioNTech Patent Right or Research Program Patent Right. BioNTech, upon request of Pfizer, agrees to
timely commence or to join in any such Enforcement Action, at Pfizer’s expense, and in any event to cooperate with Pfizer in such Enforcement Action at Pfizer’s expense. BioNTech will have the right to consult with, and provide comments
to, Pfizer about such Enforcement Action and to participate in and be represented by independent counsel in such Enforcement Action at BioNTech’s own expense, and Pfizer shall take into account any reasonable comments provided by BioNTech in
such Enforcement Action. Neither Party will incur any liability to the other Party (other than that related to a Party’s indemnification obligation pursuant to Section 11 or otherwise in this
sub-section) as a consequence of any Enforcement Action initiated or pursued pursuant to this Section 7.3.2(c) or any unfavorable decision resulting therefrom, including any decision holding any Patent
Right invalid or unenforceable. 
 (d) BioNTech Enforcement outside the Field. Subject to Section 7.3.2(b) and
7.3.2(c)and unless otherwise agreed between the Parties on a case-by-case basis, as between Pfizer and BioNTech, BioNTech shall have the sole right, but not the
obligation, to institute any Enforcement Action in the Territory in connection with any BioNTech Patent Right or Research Program Patent Right (excluding the Product Patent Rights) solely or jointly owned by BioNTech outside the Field, and any such
Enforcement Action will be at BioNTech’s expense including BioNTech indemnifying and holding harmless Pfizer and its Affiliates from and against any adverse cost award, where Pfizer or its Affiliates join any such Enforcement Action upon
BioNTech’s request or where required by Law. BioNTech will not, without the prior written consent of Pfizer, enter into any compromise or settlement relating to such Enforcement Action that (i) admits the invalidity or unenforceability of
any BioNTech Patent Right or Research Program Patent Right solely or jointly owned by BioNTech or (ii) requires BioNTech to abandon any BioNTech Patent Right or Research Program Patent Right solely or jointly owned by BioNTech. Pfizer, upon


  
 52 













 
request of BioNTech, agrees to timely commence or to join in any such Enforcement Action, at BioNTech’s expense, and in any event to cooperate with BioNTech in such Enforcement Action at
BioNTech’s expense. Pfizer will have the right to consult with, and provide comments to, BioNTech about such Enforcement Action and to participate in and be represented by independent counsel in such Enforcement Action at Pfizer’s own
expense, and BioNTech shall take into account any reasonable comments provided by Pfizer in such Enforcement Action. Neither Party will incur any liability to the other Party (other than that related to a Party’s indemnification obligation
pursuant to Section 11 or otherwise in this sub-section) as a consequence of any Enforcement Action initiated or pursued pursuant to this Section 7.3.2(d) or any unfavorable decision resulting
therefrom, including any decision holding any BioNTech Patent Right or Research Program Patent Right invalid or unenforceable. 

(e) Pfizer Patent Rights. Subject to Sections 7.3.2(b) and 7.3.2(c), Pfizer shall have the sole right, but no
obligation, to institute litigation or take other steps to remedy infringement in connection with in any field in respect of any Patent Rights that it solely owns including any Pfizer Patent Right. In the event that any such Patent Rights are based
on inventions made or created solely or jointly by BioNTech, its Affiliates or its Representatives acting on BioNTech’s behalf, BioNTech shall provide reasonable assistance to Pfizer at Pfizer’s expense in connection with such litigation.

 (f) Biosimilar Notices. 

(i) BioNTech Cooperation. Upon Pfizer’s request, BioNTech will use Commercially Reasonable Efforts to assist and
cooperate with Pfizer in (A) establishing a strategy for responding to requests for information from Regulatory Authorities and Third Party requestors and (B) preparing submissions responsive to any Biosimilar Notices received by Pfizer;
provided that Pfizer will make the final decisions with respect to such strategy and any such responses. 
 (ii)
Compliance with Biosimilar Notices. Pfizer will have the sole right in its discretion to comply with the applicable provisions of 42 U.S.C. § 262(l) (or any amendment or successor statute thereto), any similar statutory or regulatory
requirement enacted in the future regarding biologic products in the United States, or any similar statutory or regulatory requirement in any non-U.S. country or other regulatory jurisdiction, in each case,
with respect to any Biosimilar Notice received by Pfizer from any Third Party regarding any Product that is being Commercialized in the Field in the applicable jurisdiction, and the exchange of information between any Third Party and Pfizer pursuant
to such requirements; provided that, prior to any submission of information by Pfizer to a Third Party, BioNTech will have the right to review the patent information included in such proposed submission, solely with respect to BioNTech Patent
Rights, and to make suggestions as to any changes to such patent information that BioNTech reasonably believes to be necessary; provided further that Pfizer will determine the final content of any such submission. In the case of a Product
approved in the United States under the PHS Act (or, in the case of a country in the Territory other than the United States, any similar Law), to the extent permitted by applicable Law, Pfizer, as the sponsor of the application for the Product, will
be the “reference 

  
 53 













 
product sponsor” under the PHS Act. Pfizer will give written notice to BioNTech of receipt of a Biosimilar Notice received by Pfizer with respect to a Product, and Pfizer will consult with
BioNTech with respect to the selection of any BioNTech Patent Rights to be submitted pursuant to 42 U.S.C. § 262(l) (or any similar law in any country of the Territory outside the United States); provided that Pfizer will have final say
on such selection of BioNTech Patent Rights. BioNTech agrees to be bound and will cause its Affiliates and use Commercially Reasonable Efforts to cause all Third Party Licensors to be bound by the confidentiality provisions of 42 U.S.C. §
262(l)(1)(B)(iii). In connection with any action brought by Pfizer under this Section 7.3.2(f), BioNTech, upon Pfizer’s request, will reasonably cooperate and will cause its Affiliates and use Commercially Reasonable Efforts to cause all
Third Party Licensors to reasonably cooperate with Pfizer in any such action, including timely commencing or joining in any action brought by Pfizer under this Section 7.3.2(f). Solely to the extent any BioNTech Patent Rights are involved in
any such action, the Parties’ rights and responsibilities regarding any action will be determined in accordance with this Section 7.3.2(f). 

(g) Unified Patent Court. In respect of BioNTech Patent Rights, Research Program Patent Rights, Product Patent Rights
and Pfizer Patent Rights, for each and every such Patent Right having effect anywhere within any member state that was or is, from time to time, a signatory to the UPC Agreement, the Party in control of the filing, prosecution and maintenance of
such Patent Right (as determined in accordance with Section 7.3.1) shall have the sole discretion to decide whether to (i) opt in or opt out (and to opt in again), pursuant to Article 83 of the UPC Agreement, of the Unified Patent Court
system; and (ii) elect if such Patent Rights should, during their prosecution, be designated as a Unitary Patent or a European Patent. The other Party shall promptly do all things necessary and execute all documents and make all necessary
elections required to give effect to such decision(s) or election(s). 
 (h) Settlement Cross-Licensing. If pursuant to a
bona fide settlement of any Enforcement Action or Infringement Claim controlled by Pfizer, Pfizer grants to a Third Party (that was a party to the Enforcement Action or Infringement Claim) any sublicense to any of the Patent Rights licensed to
Pfizer under this Agreement in respect of that Third Party’s Competitive Product, then Pfizer shall pay to BioNTech (i) at a minimum, if such sublicense includes any of the rights granted to Pfizer under a Current License or Future
BioNTech Third Party Agreement (subject to Sections 2.1, 2.2, 2. 9), all royalties due by BioNTech to the relevant Third Party for such sublicense under any Current License and Future BioNTech Third Party Agreement in respect of licensed sales of
such Competitive Product and (ii) all other royalties received by Pfizer shall be deemed Net Sales pursuant to Section 7.3.2(c) provided that in no event shall such payment obligations exceed the maximum royalty that would be due had such
Third Party become a Sublicensee. For the avoidance of doubt, should the Third Party as part of the same agreement grant any cross-license to Pfizer for any Candidates or Products, such cross-license shall not be deemed “non-cash” consideration for the purpose of the Net Sales definition. 

  
 54 













 7.3.3. Other Actions by Third Parties. Separate from Prosecution
Proceedings, each Party will promptly notify the other Party in the event of any legal action by any Third Party involving any BioNTech Patent Right or Research Program Patent Right of which it becomes aware, including any nullity, revocation,
declaratory judgment, interference, inter partes reexamination, reexamination or compulsory license proceeding. The right to defend against any such action shall be with the Party controlling the filing, prosecution and maintenance of the
affected Patent Right (as determined in accordance with Section 7.3.1), and the provisions of Section 7.3.1 shall apply mutatis mutandis in respect of such defense. If any such action has been instituted by any Third Party in
response to, or in connection with, any Enforcement Action pursuant to Section 7.3.2, or any Enforcement Action is to be pursued as a consequence of such action being instituted by any Third Party, the Party controlling the Enforcement Action
and the Party controlling the defense shall work together and closely align their enforcement and defense strategy, which may include the (joint) appointment of the same patent counsel for all concurrent Third Party litigation and patent office
proceedings taking into account the impact on enforcement and potential for revenues relating to such Patent Rights, and in the absence of agreement, the enforcing Party shall have the final say over the Prosecution Proceedings in so far as the
Prosecution Proceeding will adversely impact the ongoing enforcement of such right, subject to having given good faith consideration to the comments and suggestions of the prosecuting Party. Further details of such joint proceeding may be agreed
between the Parties from time to time. 
 7.3.4. Purple Book Listings. To the extent of any BioNTech Patent Rights
Covering a Product, the Parties shall cooperate with each other to enable Pfizer to make filings with Regulatory Authorities, as required or allowed in connection with (i) in the United States, the FDA’s Purple Book and the Biologics Price
Competition and Innovation Act and (ii) outside the United States, under the national implementations of Article 10.1(a)(iii) of Directive 2001/EC/83 or other international equivalents thereof. Pfizer shall consider BioNTech’s reasonable
requests in connection therewith, including meeting any submission deadlines, in each case, to the extent required or permitted by applicable Law. 

7.3.5. Allegations of Infringement and Right to Seek Third Party Licenses. 

(a) Notice. If either Party becomes aware that the Development, Manufacture, Commercialization or use of any Candidate
or Product, the practice of any BioNTech Technology or Research Program Technology in the Field, or the exercise of any other right granted by BioNTech to Pfizer or any of its Affiliates or Sublicensees hereunder (collectively, the “Licensed
Activities”) is alleged by a Third Party to infringe, misappropriate or otherwise violate such Third Party’s Patent Rights or other Intellectual Property Rights or either Party otherwise identifies any Third Party Patent Rights or
other Intellectual Property Rights that may be relevant to such Licensed Activities, such Party will, as soon as reasonably practicable, notify the other Party in writing. 

(b) Pfizer Option to Negotiate. If Pfizer determines, in its sole discretion, that, in order for Pfizer, its Affiliates
or Sublicensees to engage in the Licensed Activities, it is necessary or useful to obtain a license under one or more Patent Rights or other Intellectual Property Rights Controlled by a Third Party (collectively, “Third Party IP
Rights”), then Pfizer will have the sole right, but not the obligation, to negotiate and enter into a license or other agreement with such Third Party. The amounts payable under any such license or agreement with a Third Party will reduce
Pfizer’s royalty obligations under this Agreement as and to the extent provided in Section 3.5.3(a) or as otherwise agreed between the Parties. 

  
 55 













 7.3.6. Third Party Infringement Suits. Each of the Parties will
promptly notify the other in the event that any Third Party files any suit or brings any other action alleging patent infringement by Pfizer or BioNTech or any of their respective Affiliates or Sublicensees with respect to the Development,
Manufacture, Commercialization or use of any Candidate or Product or the practice of any BioNTech Technology or Research Program Technology (any such suit or other action referred to herein as an “Infringement Claim”). In the case
of any Infringement Claim against Pfizer (including its Affiliates or Sublicensees) alone or against both Pfizer and BioNTech (including its Affiliates), Pfizer will have the right, but not the obligation, to control the defense of such Infringement
Claim, including control over any related litigation, settlement, appeal or other disposition arising in connection therewith. BioNTech, upon request of Pfizer, agrees to cooperate with Pfizer at Pfizer’s expense. BioNTech will have the right
to consult with Pfizer concerning any Infringement Claim and to participate in and be represented by independent counsel in any associated litigation in which BioNTech is a party at BioNTech’s own expense. If Pfizer elects to control the
defense of any Infringement Claim and BioNTech is obligated under Section 11.3 to indemnify Pfizer (including any Pfizer Indemnified Party) with respect to such Infringement Claim, then (a) Pfizer will bear 50% of its own attorneys’
fees incurred in investigating, preparing or defending such Infringement Claim notwithstanding the provisions of Section 11.3 and (b) BioNTech will otherwise indemnify Pfizer and any applicable Pfizer Indemnified Parties to the full extent
provided for under Section 11.3. In the case of any Infringement Claim against BioNTech alone, Pfizer will have the right to consult with BioNTech concerning such Infringement Claim and Pfizer, upon request of BioNTech, will reasonably
cooperate with BioNTech at BioNTech’s expense. Neither Party will enter into any compromise or settlement in respect of an Infringement Claim admitting or implying that the Development, Manufacture, Commercialization or use of any Candidate or
Product or the practice of any BioNTech Technology or Research Program Technology infringes Third Party patents without the other Party’s written consent. 

7.4. Enforcement of Know-How. 

7.4.1. Notification of Misappropriation. Each Party will promptly notify the other in the event of any actual, potential
or suspected misappropriation of any BioNTech Know-How or Research Program Know-How in the Territory by any Third Party. 

7.4.2. Pfizer Enforcement in the Field. As between Pfizer and BioNTech, Pfizer will have the sole right, but not the
obligation, to institute litigation or take other steps to remedy misappropriation in the Territory in connection with any BioNTech Know-How (excluding BioNTech Know-How
solely owned by Third Parties the subject of a Current Licence in so far as BioNTech has no enforcement rights in respect of the same) or Research Program Know-How in the Field, and any such litigation or
steps will be at Pfizer’s expense including Pfizer indemnifying and holding harmless BioNTech and its Affiliates from and against any adverse cost award, where BioNTech or its Affiliates join any such Enforcement Action upon Pfizer’s
request or where required by Law, subject to BioNTech’s obligation to indemnify Pfizer for such expenses pursuant to Section 11; provided that any infringement recoveries resulting from such litigation or steps relating to a claim
of Third Party misappropriation, after deducting Pfizer’s out of pocket expenses (including counsel fees and expenses including any adverse cost award) in pursuing such claim, will be deemed Net Sales. BioNTech will have no obligation to
cooperate with Pfizer in any such litigation except as set forth in this Section 7.4.2. Pfizer will not, without the prior written consent of BioNTech, enter into any compromise or settlement relating to such litigation or steps that
(a) admits that all or any portion of the BioNTech Know-How or Research Program Know-how is not 

  
 56 













 
protectable under relevant trade secret or confidentiality Laws or (b) requires Pfizer to abandon trade secret protection for any BioNTech Know-How or
Research Program Know-how. In order to establish standing, BioNTech, upon request of Pfizer, agrees to timely commence or to join in any such litigation or steps, at Pfizer’s expense, and in any event to
cooperate with Pfizer in such litigation or steps at Pfizer’s expense. BioNTech will have the right to consult with Pfizer about such litigation or steps and to participate in and be represented by independent counsel in such litigation or
steps at BioNTech’s own expense, and Pfizer shall take into account any reasonable comments provided by BioNTech in such litigation or steps. 

7.4.3. BioNTech Enforcement. As between Pfizer and BioNTech, BioNTech will have the sole right, but not the obligation,
to institute litigation or take other steps to remedy misappropriation in connection with any BioNTech Know-How or Research Program Know-how solely owned by BioNTech
outside the Field, provided that any such Know-how does not lose its confidential status as part of or in consequence of any such litigation or steps, and any such litigation or steps will be at
BioNTech’s expense including BioNTech indemnifying and holding harmless Pfizer and its Affiliates from and against any adverse cost award, where Pfizer or its Affiliates join any such Enforcement Action upon BioNTech’s request or where

BioNTech Indemnified Party. 
 11.3. Indemnification by BioNTech. BioNTech will indemnify, defend and hold harmless Pfizer, its
Affiliates, Sublicensees, contractors, distributors and each of its and their respective employees, officers, directors and agents (each, a “Pfizer Indemnified Party”) from and against any and all Liabilities that the Pfizer
Indemnified Party may be required to pay to one or more Third Parties resulting from or arising out of (i) the FIH Study, (ii) use of the BioNTech name or logo pursuant to Section 6.4.2, (iii) rights or obligations under the GEIA relating
to inventions made by employees of BioNTech or its Affiliates or Third Party Licensors in relation to BioNTech Technology or Research Program Technology used in any Candidate or Product; or (iv) the material breach by BioNTech or any of its
Representatives of any of its representations, warranties or covenants set forth in Section 9.1, Section 9.1.1, Section 9. 2, Section 9.3, Section 9.4 or Section 9.5 except to the extent caused by the negligence,
recklessness or intentional acts of Pfizer or any Pfizer Indemnified Party. 
 11.4. Procedure. 

11.4.1. Notice. Each Party will notify the other Party in writing in the event it becomes aware of a claim for which
indemnification may be sought hereunder. In the event that any Third Party asserts a claim or other proceeding (including any governmental investigation) with respect to any matter for which a Party (the “Indemnified Party”) is
entitled to indemnification hereunder (a “Third Party Claim”), then the Indemnified Party will promptly notify the Party obligated to indemnify the Indemnified Party (the “Indemnifying Party”) thereof; provided,
however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party will relieve the Indemnifying Party from any obligation hereunder unless (and then only to the extent that) the Indemnifying Party is prejudiced
thereby. 

  
 77 













 11.4.2. Control. Subject to either Party’s right to control any
actions described in Section 7 (even where the other Party is the Indemnifying Party), the Indemnifying Party will have the right, exercisable by notice to the Indemnified Party within ten Business Days after receipt of notice from the
Indemnified Party of the commencement of or assertion of any Third Party Claim, to assume direction and control of the defense, litigation, settlement, appeal or other disposition of the Third Party Claim (including the right to settle the claim
solely for monetary consideration) with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party; provided that (a) the Indemnifying Party has sufficient financial resources, in the reasonable judgment of
the Indemnified Party, to satisfy the amount of any adverse monetary judgment that is sought, (b) the Third Party Claim seeks solely monetary damages and (c) the Indemnifying Party expressly agrees in writing that as between the
Indemnifying Party and the Indemnified Party, the Indemnifying Party will be solely obligated to satisfy and discharge the Third Party Claim in full (the conditions set forth in clauses (a), (b) and (c) above are collectively referred to as the
“Litigation Conditions”). Within ten Business Days after the Indemnifying Party has given notice to the Indemnified Party of its exercise of its right to defend a Third Party Claim, the Indemnified Party will give notice to the
Indemnifying Party of any objection thereto based upon the Litigation Conditions. If the Indemnified Party reasonably so objects, the Indemnified Party will continue to defend the Third Party Claim, at the expense of the Indemnifying Party, until
such time as such objection is withdrawn. If no such notice is given, or if any such objection is withdrawn, the Indemnifying Party will be entitled, at its sole cost and expense, to assume direction and control of such defense, with counsel
selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party. During such time as the Indemnifying Party is controlling the defense of such Third Party Claim, the Indemnified Party will cooperate, and will cause its
Affiliates and agents to cooperate upon request of the Indemnifying Party, in the defense or prosecution of the Third Party Claim, including by furnishing such records, information and testimony and attending such conferences, discovery proceedings,
hearings, trials or appeals as may reasonably be requested by the Indemnifying Party. In the event that the Indemnifying Party does not satisfy the Litigation Conditions or does not notify the Indemnified Party of the Indemnifying Party’s
intent to defend any Third Party Claim within ten Business Days after notice thereof, the Indemnified Party may (without further notice to the Indemnifying Party) undertake the defense thereof with counsel of its choice and at the Indemnifying
Party’s expense (including reasonable, out-of-pocket attorneys’ fees and costs and expenses of enforcement or defense). The Indemnifying Party or the
Indemnified Party, as the case may be, will have the right to join in (including the right to conduct discovery, interview and examine witnesses and participate in all settlement conferences), but not control, at its own expense, the defense of any
Third Party Claim that the other party is defending as provided in this Agreement. 
 11.4.3. Settlement. The
Indemnifying Party will not, without the prior written consent of the Indemnified Party, enter into any compromise or settlement that commits the Indemnified Party to take, or to forbear to take, any action. The Indemnified Party will have the sole
and exclusive right to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such Third Party Claim involves equitable or other non-monetary relief, but
will not have the right to settle such Third Party Claim to the extent such Third Party Claim involves monetary damages without the prior written consent of the Indemnifying Party. Each of the Indemnifying Party and the Indemnified Party will not
make any admission of liability in respect of any Third Party Claim without the prior written consent of the other party, and the Indemnified Party will use reasonable efforts to mitigate Liabilities arising from such Third Party Claim. 

  
 78 













 11.5. Insurance. Each Party further agrees to obtain and maintain, during the
Term, commercial general liability insurance, including products liability insurance (or clinical trials insurance, if applicable), with minimum “A-” A.M. Best rated insurance carriers to cover its
indemnification obligations under Section 11.2 or Section 11.3, as applicable, in each case with limits of not less than $5,000,000 (Five Million U.S. Dollars) per occurrence and in the aggregate. All deductibles and retentions will be the
responsibility of the named insured. Within [***] days of the Effective Date, BioNTech will amend its existing insurance policies in such a way that (i) Pfizer Inc. and its Affiliates will be indemnified as principal on BioNTech’s
commercial general liability and products liability policies (or clinical trials insurance, if applicable) and (ii) Pfizer Inc. and its Affiliates will be provided a waiver of subrogation on BioNTech’s commercial general liability and products
liability policies (or clinical trials insurance, if applicable). For U.S. exposures, additional insured status on BioNTech’s commercial general liability and products liability policies shall be via form CG20101185 or its equivalent. Products
liability coverage shall be maintained for three years following termination of this Agreement. To the extent of its culpability or negligence, all coverages of BioNTech will be primary and non-contributing
with any similar insurance, carried by Pfizer. Notwithstanding any provision of this Section 11.5 to the contrary, Pfizer may meet its obligations under this Section 11.5 through self-insurance. Neither Party’s insurance will be
construed to create a limit of liability with respect to its indemnification obligations under this Section 11. 
  

	12.	 MISCELLANEOUS

 Exhibit B 

PFIZER ANTI-BRIBERY AND ANTI-CORRUPTION PRINCIPLES 

Pfizer has a longstanding corporate policy that prohibits colleagues or anyone acting on our behalf from providing any payment or benefit to any person or
entity in order to improperly influence a government official or to gain an unfair business advantage. Pfizer is committed to performing with integrity, and acting ethically and legally in accordance with all applicable laws and regulations,
including, but not limited to, anti-bribery and anti-corruption laws. We expect the same commitment from the consultants, agents, representatives or other companies and individuals acting on our behalf (“Business Associates”), as well as
those acting on behalf of Business Associates, in connection with work for Pfizer. 
 Bribery of Government Officials 

Most countries have laws that forbid making, offering or promising any payment or anything of value (directly or indirectly) to a government official when the
payment is intended to influence an official act or decision to award or retain business. Under Pfizer’s policies, “government official” is broadly interpreted and includes: (i) any elected or appointed government official (e.g.,
a member of a ministry of health); (ii) any employee or person acting for or on behalf of a government official, agency, or enterprise performing a governmental function; (iii) any political party, candidate for public office, officer,
employee, or person acting for or on behalf of a political party or candidate for public office; or (iv) an employee or person acting for or on behalf of a public international organization (e.g., the United Nations). “Government” is
meant to include all levels and subdivisions of governments (i.e., local, regional, or national and administrative, legislative, or executive). Because this definition of “government official” is so broad, it is likely that Business
Associates will interact with a government official in the ordinary course of their business on behalf of Pfizer. For example, doctors employed by government-owned hospitals would be considered “government officials” under Pfizer’s
policies. 
 The U.S. Foreign Corrupt Practices Act of 1977 (the “FCPA”) prohibits making, promising, or authorizing the making of a payment or
providing anything of value to a non-U.S. government official to improperly or corruptly induce that official to make any governmental act or decision to assist a company in obtaining or retaining business, or
to otherwise obtain an improper advantage. The FCPA also prohibits a company or person from using another company or individual to engage in any of the foregoing activities. As a U.S. company, Pfizer must comply with the FCPA and could be held
liable as a result of acts committed anywhere in the world by a Business Associate. 
 Anti-Bribery and Anti-Corruption Principles Governing Interactions
with Governments and Government Officials 
 Business Associates must communicate and abide by the following principles with regard to their interactions
with governments and government officials: 
  

	 	•	 	 Business Associates, and those acting on their behalf in connection with work for Pfizer, may not directly or
indirectly make, promise, or authorize the making of a corrupt payment or provide anything of value to any government official to induce that government official to make any governmental act or decision to help Pfizer obtain or retain business.
Business Associates, and those acting on their behalf in connection with work for Pfizer, may never make a payment to or offer a government official any item or benefit, regardless of value, as an improper inducement for such government official to
approve, reimburse, prescribe, or purchase a Pfizer product, to influence the outcome of a clinical trial, or otherwise improperly to benefit Pfizer’s business activities. 



 

	 	•	 	 Business Associates, and those acting on their behalf in connection with work for Pfizer, need to understand
whether local laws, regulations, or operating procedures (including requirements imposed by government entities such as government-owned hospitals or research institutions) impose any limits, restrictions, or disclosure requirements on compensation,
financial support, donations, or gifts that may be provided to government officials. Business Associates, and those acting on their behalf in connection with work for Pfizer, must take into account and comply with any applicable restrictions in
conducting their Pfizer-related activities. If a Business Associate is uncertain as to the meaning or applicability of any identified limits, restrictions, or disclosure requirements with respect to
interactions with government officials, that Business Associate should consult with his or her primary Pfizer contact before undertaking their activities. 



  
 91 














	 	•	 	 Business Associates, and those acting on their behalf in connection with work for Pfizer, are not permitted to
offer facilitation payments. A “facilitation payment” is a nominal, unofficial payment to a government official for the purpose of securing or expediting the performance of a routine,
non-discretionary governmental action. Examples of facilitation payments include payments to expedite the processing of licenses, permits or visas for which all paperwork is in order.In the event that a
Business Associate, or someone acting on their behalf in connection with work for Pfizer, receives or becomes aware of a request or demand for a facilitation payment or bribe in connection with work for Pfizer, the Business Associate shall report
such request or demand promptly to his or her primary Pfizer contact before taking any further action. 


 Commercial Bribery 

Bribery and corruption can also occur in non-government, business to business relationships.Most countries have laws
which prohibit offering, promising, giving, requesting, receiving, accepting, or agreeing to accept money or anything of value in exchange for an improper business advantage. Examples of prohibited conduct could include, but are not limited to, the
provision of inappropriate gifts or hospitality, kickbacks, or investment opportunities offered to improperly induce the purchase of goods or services. Pfizer colleagues are not permitted to offer, give, solicit or accept bribes, and we expect our
Business Associates, and those acting on their behalf in connection with work for Pfizer, to abide by the same principles. 
 Anti-Bribery and
Anti-Corruption Principles Governing Interactions with Private Parties and Pfizer Colleagues 
 Business Associates must communicate and abide by the
following principles with regard to their interactions with private parties and Pfizer colleagues: 
  

	 	•	 	 Business Associates, and those acting on their behalf in connection with work for Pfizer, may not directly or
indirectly make, promise, or authorize the making of a corrupt payment or provide anything of value to any person to induce that person to provide an unlawful business advantage for Pfizer. 



 

	 	•	 	 Business Associates, and those acting on their behalf in connection with work for Pfizer, may not directly or
indirectly, solicit, agree to accept, or receive a payment or anything of value as an improper inducement in connection with their business activities performed for Pfizer. 



 

	 	•	 	 Pfizer colleagues are not permitted to receive gifts, services, perks, entertainment, or other items of more than
token or nominal monetary value from Business Associates, and those acting on their behalf in connection with work for Pfizer. Moreover, gifts of nominal value are only permitted if they are received on an infrequent basis and only at appropriate
occasions. 


 Reporting Suspected or Actual Violations 

Business Associates, and those acting on behalf in connection with work for Pfizer, are expected to raise concerns related to potential violations of these
International Anti-Bribery and Anti-Corruption Principles or the law. Such reports can be made to a Business Associate’s primary point of contact at Pfizer, or if an Associate prefers, to Pfizer’s Compliance Group, by e-mail at corporate.compliance@pfizer.com or by phone at 1-212-733-3026.

 Exhibit C 

Pfizer’s Corporate Policy regarding Animal Care and Use (v. 1.2, June 18, 2017) 

BACKGROUND 
 Pfizer is dedicated to helping people and
animals live longer, healthier lives through the discovery and development of breakthrough medicines and therapies. Animal-based biomedical research in the pharmaceutical industry remains a vital component of the discovery, evaluation and regulatory
processes, which lead to the development of products that save or improve human lives throughout the world. Pfizer’s Animal Care and Use policy reflects our absolute commitment that all animals used by our business are treated humanely. This
means that any research involving animals is conducted only after appropriate ethical consideration and review. This review ensures that we provide a high level of care to all animals used, and that a scientifically appropriate and validated
alternative to the use of animals is not available. 
 Why We Conduct Animal-based Biomedical Research 

Pfizer is ethically and legally obliged to rigorously evaluate potential new medicines and therapies. Many of these evaluations can be, and are, accomplished
by techniques that do not require the use of animals. However, given the present state of scientific knowledge, testing potential new medicines and therapies in animals is frequently critical to their evaluation, and is required by regulatory
authorities worldwide to ensure the quality, efficacy and safety of the medicines we discover. 
 Pfizer’s Commitment to Ethical and Humane
Treatment of Animals 
 Pfizer accepts its responsibility to use animals in a humane and ethical manner and expects all Colleagues to treat animals with
respect. We approach the use of animals in our business with a high level of humane and ethical concern for those animals. All use is carefully planned and conducted in such a way as to minimize or avoid pain, distress, or discomfort to the animals.
Every proposed use is thoroughly evaluated before being undertaken as the health and well-being of all animals under our care is a primary concern. Similarly, we expect any Third Party organization we engage to conduct animal-based research on our
behalf to adhere to this Policy and to comply with all applicable laws and regulations. 
 Pfizer’s Commitment to Alternatives to Animal-based
Biomedical Research 
 Pfizer is fully committed to the development and use of scientifically validated alternative testing methods that are acceptable
to regulatory authorities and do not compromise patient safety or the effectiveness of our medicines. Pfizer continues to engage and lead cross-industry efforts aimed at developing and refining new in-vitro
testing and predictive informatics-based systems that hold promise for future reduction of animal usage. Pfizer works directly with regulators and through pharmaceutical trade organizations to increase the recognition and acceptance of alternative
models where such alternatives can be used appropriately. 
 POLICY 

For as long as it remains necessary to use animals in the discovery, development,evaluation and production of new medicines, we commit to maintaining high
standards in the humane treatment of these animals. Significantly, we embrace the principles known as the “3Rs” of animal research first proposed in 1959 by Russell and Burch to describe the use of alternatives in animal research. These
are: 
 Replacement of animal experiments with non-animal experiments such as mathematical models, computer
simulations, and in-vitro biological systems wherever appropriate; and where animals must be used; 
 Reduction
of the numbers of animals used in each study, and of the number of studies involving animals, to the absolute minimum necessary to obtain valid results and achieve our research objectives; and 

Refinement of procedures involving animals to minimize the potential for pain and distress.

 In addition to the 3R’s, and to further assure we maintain high standards for our animals, we have
adopted the following guidelines: 
  

	 	•	 	 When animal experimentation is necessary, great care is taken to choose the most appropriate animal species for
the research and to optimize the study design to ensure that the results will be as meaningful as possible. 


  

	 	•	 	 Non-human primates will only be used when scientifically justified, for
example in cases where other species will not provide sufficiently close analogues to the biological pathways and responses expected in humans. 


  

	 	•	 	 All studies are carefully designed to gain the maximum information from the fewest number of animals possible.



  

	 	•	 	 Each proposed use of animals is reviewed and approved by a panel of objective experts prior to performing any
experiments to ensure that the use of the animals is consistent with sound scientific practices and ethical considerations. 


  

	 	•	 	 Our standards of animal care and welfare meet or exceed those required by applicable local, national, or
international laws and regulations. 


  

	 	•	 	 We regularly monitor our animals for signs of ill health or distress and take prompt action wherever appropriate.
We make veterinary care available to our animals at all times. 


  

	 	•	 	 Our veterinarians and scientists evaluate every proposed animal procedure with an emphasis on eliminating or
minimizing any potential for pain or distress which may be experienced by the animals. 


  

	 	•	 	 We train all Colleagues involved in the care, welfare and use of animals to ensure (a) that they are
competent in the care of the animals and in the procedures required to complete the proposed work; (b) that they are aware of the ethical issues involved in the use of animals; and (c) that they demonstrate respect and humane treatment
towards the animals in their care. 


  

	 	•	 	 We expect our contract research organizations, collaborators and vendors to maintain similar high standards.
Parties conducting animal based research for Pfizer at their facilities are required to adhere to this Policy and to comply with all applicable laws and regulations. We perform welfare audits of Third Party facilities in accordance with our quality
assurance policies. 


  

	 	•	 	 Because respect is a key tenant in our use of animals, we have also established standards regarding the use of
animals in the marketing of Pfizer products. If advertisements featuring animals are used, any animal shown should be healthy and in a natural or appropriate setting. Non-human primates should not be used in
the advertising of Pfizer products, and other wild animals will also not be used unless they are shown in their natural setting or portrayed through animation or computer-generated graphics. 



This Policy represents Pfizer’s commitment to high-quality animal care and welfare throughout our business, and to the replacement, reduction and
refinement of the use of animals in research. We are equally committed to bringing important and safe new medicines to patients.

 Schedule 10.7.1(a) 

Effects of Reversion Rights in case of Termination for Cause by BioNTech or Termination for Convenience by Pfizer 

In the event BioNTech notifies Pfizer pursuant to Section 10.7.1(a)(ii) that it desires a license to the Continuation Product, the following terms and
conditions shall apply: 
  

	 	1.	 Within the time periods set forth in Section 10.7.1(a)(ii), if requested by BioNTech, the Parties will,
subject to the terms of the license described in Section 10.7.1(a)(ii)(C), mutually agree upon a transition plan to effect an orderly and timely transition to BioNTech of all Development, Manufacture and Commercialization activities and
responsibilities with respect to Continuation Products (a “Transition Plan”). Any and all support provided by Pfizer with respect to the Transition Plan shall be at the BioNTech’s cost and expense. 



 

	 	2.	 To the extent permitted by Law and requested by BioNTech, assignment and transfer by Pfizer to BioNTech of all
Regulatory Materials Controlled by Pfizer solely relating to the Continuation Products in the Territory, and not relating to any other product. If Pfizer is restricted from assigning or transferring ownership of any of the foregoing items to
BioNTech, and in respect of Regulatory Materials Controlled by Pfizer and necessary or useful for the Development, Manufacturing or Commercialization of the Continuation Products in the Territory, Pfizer shall use its Commercially Reasonable Efforts
to grant BioNTech (or its designee) a right of reference or use to such item and Pfizer shall take reasonable actions that are reasonably necessary to effect such assignment and transfer or grant of right of reference or use to BioNTech (or its
designee), at BioNTech’s sole expense, including by making such filings as may be reasonably required with Regulatory Authorities in the Territory that may be necessary to record such assignment or effect such transfer and, at BioNTech’s
written request complete any pending regulatory filings with respect to all Continuation Products. For purposes of this Schedule 10.7.1(a), “Regulatory Materials” means all regulatory registrations, applications,
authorizations and approvals (including approvals of BLAs, supplements and amendments, pre- and post-approvals, pricing and Third Party reimbursement approvals, and labeling approvals), Regulatory Approvals or
other submissions made to or with any Regulatory Authority necessary for the Development (including the conduct of clinical studies), Manufacture or Commercialization of a Continuation Product in a regulatory jurisdiction, together with all related
correspondence to or from any Regulatory Authority and all documents referenced in the complete regulatory chronology for each BLA, including all INDs, clinical trial applications and foreign equivalents of any of the foregoing.



  

	 	3.	 Upon BioNTech’s written request, assignment and transfer by Pfizer to BioNTech of its entire right, title,
and interest in and to all pharmacological, toxicological and clinical test data and results, research data, reports and batch records, safety data and all other data Controlled by Pfizer and reasonably in its possession as of the effective date of
termination and generated in the Development, Manufacture or Commercialization of Continuation Products, at BioNTech’s sole expense, subject to a retained non-exclusive right by Pfizer to use such data
for research purposes and to continue prosecution of any Patent Rights Controlled by Pfizer and its Affiliates in the course of conducting its activities under this Agreement. 



 

	 	4.	 Any supply agreement entered into by the Parties pursuant to the Agreement shall terminate. If Pfizer has, at
such time of termination, established its own supply and is capable of supplying the Continuation Product without breaching applicable Law and to the extent not prevented by technical or force majeure




  
 107 














	 	
(as defined in Section 12.4 of the Agreement) conditions, and if BioNTech so requests, the Parties shall negotiate in good faith as soon as reasonably possible (with a target date of [***]
days from the termination effective date) a supply agreement under which Pfizer would supply BioNTech with transitional supply of such Continuation Product at [***] and on commercially reasonable terms for a commercially reasonable period of time of
up to [***]months. During the negotiation period, Pfizer will provide a continued supply of the Continuation Product to BioNTech for BioNTech’s demand of Continuation Product for BioNTech’s or its Affiliates Development or
Commercialization of the Product at [***] (provided that such demand does not exceed Pfizer’s anticipated forecasts (prior to termination of this Agreement). The transfer of the applicable Manufacturing process from Pfizer to BioNTech or its
designee will be part of the transition planning pursuant to Section 1 above. 

  

	 	5.	 BioNTech shall have the first right to file, prosecute, maintain, defend and enforce any Product Patent Rights
included in the Reversion Technology; provided, however, that if Pfizer requests, Pfizer shall be granted the right to review and comment on such Product Patent Rights. 



 

	 	6.	 Pfizer shall receive the following percentage of the royalties set forth in the table in Section 3.5.1 of
the Agreement in respect of Continuation Product Net Sales during the Continuation Product Royalty Term: 


  

			
	[***]	  	

  

	 	(A)	 “Continuation Product Net Sales” shall be on the same basis as if BioNTech was Pfizer in the
definition of Net Sales. 


  

	 	(B)	 “Continuation Product Royalty Term” shall be on the same basis as if BioNTech was Pfizer in
the definition of Royalty Term (or defined terms used in that definition). 


  

	 	7.	 Pfizer shall have the same reporting, audit and other rights with respect to the royalties to be paid by
BioNTech to Pfizer under this Schedule 10.7.1(a) as are afforded by Pfizer to BioNTech under the Agreement. 


  

	 	8.	 Section 3.5.3 of the Agreement would apply mutatis mutandis to BioNTech with respect to the
Continuation Product, provided, however that: 


  

	 	(A)	 BioNTech shall maintain its books and records in accordance with IFRS, as consistently applied by BioNTech with
respect to sales of the Product, rather than GAAP; 


  

	 	(B)	 Pfizer shall not be obliged to share or be responsible for any payments to any Third Party in respect of the
Candidates or Products under any royalty stacking provisions or Third Party Patents, and BioNTech shall be responsible for all Third Party payment obligations and responsibilities concerning Third Party Patents; and 



  
 108 














	 	(C)	 BioNTech shall be responsible for and indemnify Pfizer for any breach or liability arising under any agreement
between Pfizer and a Third Party concerning Patent Rights licensed in by Pfizer in connection with any Candidate or Product.
