(US$55,000,000.00) (the “Foundation Investment”) in ordinary shares of BioNTech SE, a Societas Europaea (the “Company”, with such shares being referred to as the “Foundation
Shares”), at a purchase price of US$ 18.10 per share, whereby such shares will, on the basis of pertinent contractual arrangements, enjoy certain preferences to be established by an amendment to the shareholders’ agreement for the
Company in such form as the Foundation and the Company may agree (such shareholders’ agreement as so amended the “Amended SHA”). The Foundation is making the Foundation Investment to induce the Company to perform the Global
Access Commitments set forth herein, and the Company acknowledges and agrees that it would not undertake such Global Access Commitments absent the Foundation Investment. The Foundation Investment will be made in accordance with an investment
agreement to be entered into on or about the date hereof in such form as the Foundation and Company may agree (the “Investment Agreement”), the Amended SHA, this Letter Agreement, and any additional agreements executed in connection
therewith (collectively, and together with any additional agreements that may be executed in connection with the Foundation Investment, in each case as amended from time to time in accordance with their terms, the “Investment
Documents”). The Foundation Investment is conditioned upon (i) the execution and delivery of the applicable Investment Documents by the parties thereto, (ii) the Investment Agreement becoming unconditional in all respects (save
only for any condition relating to the completion of this Letter Agreement) and (iii) the Foundation obtaining a written legal opinion from tax counsel that the Foundation Investment will qualify as a program-related investment under the Code.
This Letter Agreement shall terminate in the event that Closing of the Foundation Investment (as defined in Section 1 below) and the issuance of the Foundation Shares pursuant to the terms of the Investment Agreement do not occur.

prophylactics to reduce the burden of disease in developing countries in furtherance of its mission to help all people lead healthy, productive lives. The Foundation’s primary purpose in making the Foundation Investment is to secure Global
Access to new, low-cost products and services developed through the use of the Company’s proprietary capabilities and intellectual property all as contemplated herein, including (i) research
capabilities across all of the Company’s Platform Technology which are specifically utilized in the HIV Project, TB Project and/or in one or more Additional Projects, (ii) Foundation-supported product candidates related to the
Foundation’s target diseases for use in the developing world and (iii) product development capabilities (collectively, the “Charitable Purpose”). In furtherance of the Charitable Purpose, the Foundation Investment will
secure the Global Access Commitments described below. 
 (b)    Use of Proceeds. The proceeds from the Foundation
Investment will be used solely in furtherance of the Charitable Purpose to: 
 (i)    officially establish and build the
infectious disease capabilities of the Company in accordance with Section 3(i) with a budget of EUR 16.15 million, including costs for new FTEs, infrastructure (labs and facilities) and further developing the technology platforms
(including taking further licenses to technology) to enable the Company to complete the Projects; 
 (ii)    conduct the
Initial HIV SOW; and 
 (iii)    conduct the Initial TB SOW. 

The proceeds from the Foundation Investment will not be required to be segregated in a separate account. 

3.    Global Access Commitments. 

As a condition to the Foundation making the Foundation Investment and to ensure satisfaction of the Charitable Purpose and Global Access,
the Company agrees to the following (collectively “Global Access Commitments”): 

  
 6 













 (a)    Performance of Initial Scopes of Work. 

(i)    The Company will use the Foundation Investment to complete the work packages set forth in the Initial HIV SOW and
the Initial TB Project SOW. In the event that during the course of performing the Initial HIV SOW and the Initial TB SOW the Company determines that the costs are reasonably likely to exceed the aggregate agreed budget for such Projects of [***] and
the Company has used good faith efforts to adhere to the agreed budget and the parties have not materially modified the Initial HIV SOW or the Initial TB SOW, the Company will provide estimates for the additional costs and the reasons for the
proposed additional costs to the Joint Steering Committee. The Joint Steering Committee will determine whether additional costs are necessary and the amount of such costs. The Company and the Foundation will determine in good faith a reasonable
allocation of such additional costs between the Company and the Foundation or Foundation-supported Entities. If [***], as applicable. 

(ii)    If the parties mutually agree to make any material modifications to the Initial HIV SOW or the Initial TB SOW that
impact the budget for such Projects, then at the time of such modification the parties will agree upon the new budget, and the [***] described in subsection (i) above will be based on the adjusted budget. 

(iii)    After the Company has completed the Initial HIV SOW and/or the Initial TB SOW, the Foundation will have the right,
at its discretion (subject to the Company’s right to decline any additional funding to the extent permitted by Section 3(d)(v) below), to continue providing funding (directly or through a Foundation-supported Entity) to advance the HIV
Project and/ or TB Project through commercialization and distribution of a final product in accordance with the HIV TPP, TB POI TPP and/or TB POD TPP, as applicable, in accordance with Section 3(d) below. Depending upon the achievement of
Project progress-driven milestones, which may be defined in the respective Project statements of work, the parties currently anticipate that the total potential grant funding relating to Projects (including Projects funded by Foundation-supported
Entities) could reach up to forty-five million dollars (USD$45,000,000.00), provided that any such additional grant funding will be in the Foundation’s discretion and subject to execution of grant documents for such Projects in accordance with
the Foundation’s standard grant making process. 
 (b)    Additional Projects. If requested by the
Foundation, at its discretion, and subject to the terms herein, the Company will utilize the Platform Technology to diligently conduct up to three (3) Additional Projects (in addition to the HIV Project and TB Project). The Foundation, at its
discretion, can select the Additional Projects from the list of diseases set forth on Part A of Appendix C. For the avoidance of doubt, the Additional Projects will not be funded by the Foundation Investment except in the limited
circumstances following a determination that it is futile to continue with a workplan as set forth in the TB Project Statement of Work or HIV Project Statement of Work. If the Foundation elects to proceed with one or more Additional Projects, it
will provide additional funding as described herein. The Company and the Foundation can work on more than three (3) Additional Projects in parallel if they mutually agree to do so. The Foundation will have five (5) years from the Closing
of the Foundation Investment to identify Additional Projects. The initial scope of work (to be financed with additional funding from the Foundation except in the limited circumstances following a determination that it is futile to


  
 7 













 
continue with a workplan as set forth in the TB Project Statement of Work or HIV Project Statement of Work) for all Additional Projects, regardless of the individual Project’s start date,
will be structured in such a way that it is scheduled to be completed by the eighth (8th) anniversary of the Closing of the Foundation Investment (the “Completion Date”). Following the Completion Date, the Company will have the
right to accept or decline any additional funding for any additional work under such Additional Projects as described in Section 3(d)(v) below, provided that the Global Access Commitments shall continue to apply with respect to the Funded
Developments (and to the Platform Technology to the extent required to further develop and commercialize the Funded Developments in accordance with this Letter Agreement) developed to, or existing at the Completion Date. If the Foundation elects to
proceed with all three (3) Additional Projects, at least one of such projects will be related to malaria. 

(c)    Performance of Projects. The Company will perform all Projects in good faith using substantially the same
level of efforts, resources, time, and expediency as are consistent with the practices of the Company with respect to the research and development, regulatory approval and commercialization of any other Company products at a similar stage in
development, including the Company’s commercial products intended for markets other than in Developing Countries. 

(d)    Further Development. 

(i)    If the Foundation elects at any time to proceed either with additional work on the HIV Project, TB Project or any
Additional Project, the Foundation and the Company will agree in good faith on one or more subsequent statements of work, which may include applicable development, commercialization and associated activities conducted by the Company and potentially
one or more partner(s) that are not Direct Competitors as agreed by the Company and the Foundation, including seeking applicable country-level regulatory approvals. Such partner may include the Gates MRI if requested by the Foundation and agreed to
by the Gates MRI and the Company. 
 (ii)    If the Foundation requests the Company to continue work on the HIV Project,
the TB Project and/or any Additional Project, any additional funding from the Foundation or a Foundation-supported Entity will be provided pursuant to the Foundation’s standard funding terms and processes. The specific level and allocation of
funding responsibilities between the parties (and potentially Foundation-supported Entities) for any such Project will be mutually agreed in good faith in writing by the parties to fairly allocate the expected benefits between Developing Countries
and developed countries. 
 (iii)    Any agreements for further work relating to the HIV Project and/or TB Project or for
an Additional Project will include a proposal describing the relevant work (including specific Global Access Commitments) and other related documents acceptable to the Foundation and the Company including a manufacturing, commercialization and
distribution plan for the Developing Countries taking into account the Company’s actual and projected capabilities at the time of developing such plan, and will be consistent with the HIV TPP, the TB POI TPP, the TB POD TPP and/or any TPP
relating to an Additional Project, as applicable. The applicable funding agreements will also include a mutually acceptable license to the Funded Developments developed or acquired (including in-licensed) by
the Company in connection with the Company’s conduct of 

  
 8 













 
such work and the Platform Technology to the extent required to further develop and commercialize the relevant Product(s). The terms of such license will be no less favorable to the Foundation
than the terms of the Global Health License, unless mutually agreed otherwise by the parties in their respective discretion. 

(iv)    If the Foundation desires to continue funding as set forth herein to advance the HIV Project, TB Project and/or any
Additional Project through commercialization and distribution of a final product, but the Company reasonably believes that such further product development is not feasible due to scientific or technical failure or would cause a material adverse
effect on the Company, then the matter will be submitted to the Joint Steering Committee. If the members of the Joint Steering Committee do not mutually agree with the Company’s determination then the matter will be resolved in accordance with
the dispute resolution process set forth in Section 20 below. 
 (v)    Notwithstanding the foregoing, the Company
will have the right to decline any additional funding or extension of (1) the TB Project following completion of the Initial TB SOW and either the occurrence of an Event Stamp TB or in accordance with Section 3(d)(vi)(B), (2) the HIV
Project following completion of the Initial HIV SOW and either the occurrence of an Event Stamp HIV or in accordance with Section 3(d)(vi)(B) and (3) any Additional Project following the Completion Date or in accordance with
Section 3(d)(vi)(B). If the Foundation desires to continue funding the HIV Project, the TB Project and/or any Additional Project and the Company does not agree to accept such additional funding and continue development of the applicable Project
to the extent permitted by (1), (2) or (3) above (each such case a “Company Election Not to Proceed”), then the commitments described in Sections 3(d)(v)(A) and 3(d)(v)(B) will apply. 

(A)    Further Development Activities Following a Company Election Not to Proceed 

(1)    If elected by the Foundation, and subject to the agreement of the Gates MRI, the Company will grant a license
equivalent to the Global Health License to the Gates MRI and a license in accordance with Section 3(d)(v)(B)(3) to the Manufacturing Partner identified pursuant to the process set forth below and will undertake associated technology transfer
activities to the extent reasonably required for the further development and manufacturing (if applicable) of the applicable Product pursuant to a development plan on reasonable market terms. 

(2)    If the Foundation does not make the election set forth in Section 3(d)(v)(A)(1) above, the Company will use
reasonable best efforts to identify a third party that is reasonably acceptable to the Foundation to continue development of the applicable Product (which third party may also be the Manufacturing Partner identified below). If a third party is not
selected to continue development of the applicable Product pursuant to the previous sentence, the Foundation will have the right to identify a third party that is not a Direct Competitor to continue development of the applicable Product (which third
party may also be the Manufacturing Partner identified below). The Gates MRI or the third-party identified pursuant to this clause 3(d)(v)(A)(2) is referred to as the “Development Partner”. 

  
 9 













 (3)    The Company will grant a license equivalent to the Global Health
License to the Development Partner and, unless the Company is manufacturing all Product required by the Development Partner, a license in accordance with Section 3(d)(v)(B)(3) to the Manufacturing Partner identified pursuant to the process set
forth below if the Development Partner is not also the Manufacturing Partner, and will undertake associated technology transfer activities to the extent reasonably required for the further development of the Product. In addition, [***]. The Company
will notify the Foundation at least 10 days [***]. The Company may request from any Development Partner that (1) its name and/or logo must be appropriately displayed on any Product (or any related marketing materials, leaflets or packaging)
that will be distributed by any Foundation-supported Entity (which may include the Development Partners, Manufacturing Partners or sublicensees) under this Letter Agreement and (2) the Development Partner adequately mentions the Company as the
technology provider to the extent applicable in any public statements or disclosures relating to any Product. 

(B)    Further Manufacturing Activities Following a Company Election Not to Proceed: 

(1)    If requested by the Company, the Company shall have the right to manufacture all Product required by the
Development Partner under a manufacturing agreement to be concluded between the Company and the Development Partner. 

(2)    If the Company does not request to manufacture the Product and the Development Partner identified above is unable
or unwilling to manufacture the applicable Product, the Company will use reasonable best efforts to identify a third party that is reasonably acceptable to the Foundation to manufacture the Product, including considering in good faith potential
manufacturers proposed by the Foundation. The third-party identified pursuant to this Section 3(d)(v)(B)(2) with whom the Development Partner has concluded an agreement with respect to the manufacture of the Product is referred to as the
“Manufacturing Partner”. 
 (3)    The Company will grant a
non-exclusive license to the Manufacturing Partner to the extent required for the Manufacturing Partner to fulfill its manufacturing obligations related to the Product for the Development Partner for
Developing Countries and will undertake associated technology transfer activities on reasonable market terms to the extent reasonably required for the manufacturing of the Product. If [***]. The Company may request from any Manufacturing Partner
that (i) its name and/or logo must be appropriately displayed on any Product (or any related marketing materials, leaflets or packaging) manufactured by such Manufacturing Partner and (ii) the Manufacturing Partner adequately mentions the
Company as the technology provider to the extent applicable in any public statements or disclosures relating to any Product. 

(4)    If a Manufacturing Partner is not identified pursuant to Section 3(d)(v)(B)(2) , the Company will manufacture
the initial supply of the relevant Product required for the immediate planned clinical study and will continue to supply Product for subsequent trials until a Manufacturing Partner is identified. The Company will continue to apply reasonable best
efforts to identify a Manufacturing Partner during this time. 

  
 10 













 (5)    If a Manufacturing Partner is not identified by the Company
within a reasonable time prior to market approval of the applicable Product, the Company will, provided it has a facility to provide commercial manufacturing quantities for the applicable Product, manufacture the commercial supply of the Product
under a contract manufacturing agreement to be concluded on reasonable market terms between the Company and the Development Partner until a suitable Manufacturing Partner is identified. If the Company does not have an adequate commercial
manufacturing capability to manufacture a sufficient quantity of the applicable Product and a Manufacturing Partner has not been identified, the Company will build such a facility (or increase the capacity of an existing facility) to meet the
manufacturing, commercialization and distribution requirements agreed by the Foundation and the Company in good faith in the relevant grant proposal document for the relevant Product. The funding for such build will be mutually agreed in good faith
in writing by the Foundation and the Company to fairly allocate the expected benefits between Developing Countries and developed countries. If at any time following the commencement of such build a Manufacturing Partner is identified, the Company
may choose (in its sole discretion) to either (X) initiate or continue (as the case may be) the manufacturing or (Y) grant a manufacturing license to such Manufacturing Partner and to provide technology transfer activities on reasonable
market terms to such Manufacturing Partner to the extent reasonably required for such manufacturing. For the avoidance of doubt, during the time that the Company is building a facility or increasing the capacity of an existing facility pursuant to
this Section 3(d)(v)(B)(5) , it will not be required to reduce the commercial manufacturing output at its existing facilities in order to accommodate manufacturing additional Products beyond what it has already committed to manufacture. 

(6)    For clarity, the licenses granted pursuant to Sections 3(d)(v)(A) and 3(d)(v)(B) (and associated technology
transfer obligations) will not be subject to any Exercise Events. These licenses and activities will be documented in agreements between the Company and the relevant party entered into as soon as reasonably possible. When a license is required to be
granted under the terms stated above, the relevant parties may agree to a broader license but under no circumstance (except for the license granted pursuant to Section 3(d)(v)(B)(3) ) will the license be more restrictive than the Global Health
License required under this Letter Agreement. All manufacturing and related activities to be performed by the Company under this Section 3(d)(v)(B) (including logistics, warehousing, transport, etc.) shall be charged by the Company at Fully
Loaded Costs of the relevant Product (excluding, for the avoidance of doubt, the manufacturing for developed countries which have been licensed to the Development Partner). 

(vi)    Prior to [***], as applicable: 

(A)    If [***]. 

(B)    If [***]. 

(vii)    If at any time the Foundation does not elect to proceed with additional work on a Project or further development
of a Product, including following a Foundation Election Not to Proceed, (A) the Global Access Commitments shall continue to apply with respect to the Funded Developments (and to the Platform Technology to the extent required to further develop
and commercialize the Funded Developments in accordance with this Letter Agreement) developed to, 

  
 11 













 
or existing at the time the Foundation ceases to proceed with funding additional work or further development (but, for the avoidance of doubt, not with respect to any developments made by or on
behalf of the Company after such point if the Company decides to continue the development outside of the scope of this Letter Agreement), (B) the Foundation will have the right at any time to elect to proceed with additional work on such
Project or further development of such Product in accordance with this Section 3(d) and the Company will continue such development or, if the Company declines to continue such development as permitted in Section 3(d)(v), the commitments
described in Sections 3(d)(v)(A) and 3(d)(v)(B) will apply and (C) the Company will not grant to a third-party any rights or enter into any arrangements or agreements or otherwise take any actions that would limit or restrict the Global Access
Commitments with respect to the Funded Developments, including as described in subsections (A) and (B) above. 

(e)    Pandemic Response. If during the conduct of the HIV Project Statement of Work or TB Project Statement of Work
there is a need for an emergency response to a pandemic of an infectious disease that has not already been partnered with a third party [***], the Foundation can request the Company to accept a grant-funded project in response to such pandemic, and
the Company may elect to accept such funding at its sole discretion, which may include the development of a drug, vaccine or diagnostic, and the Company will negotiate in good faith with the Foundation to reach agreement on such pandemic response
project. 
 (f)    Access to Products Developed for Excluded Diseases. If the Company obtains regulatory approval
for any product(s) for the treatment or prevention of any of the Excluded Diseases and has not entered into a binding agreement with a third party on an exclusive basis with respect to the manufacturing, distribution and/or commercialization of such
product, then the Company agrees to consider in good faith any request from the Foundation regarding providing access to such product in Developing Countries at an affordable price. The parties acknowledge that if the Foundation requests such
access, providing access may require further financial support from the Foundation or a Foundation-supported Entity to the Company. For clarity, under no circumstances will any of the Excluded Diseases be the subject of any Additional Project unless
agreed by the Company in its sole discretion. 
 (g)    Receipt and Continuation of Licenses. The Company shall
continue to maintain all necessary licenses and rights with respect to the Platform Technology and Funded Developments needed to perform the Global Access Commitments. If the Company wishes to discontinue any such license or right, it shall request
the Foundation’s prior written approval (which shall not be withheld by the Foundation unreasonably). In the event that licenses described in the previous sentence are received from one or more Foundation-supported Entities, then in addition to
and without jeopardizing such licenses, the Company will have the right at its own cost and without assistance from the Foundation to seek to negotiate with such Foundation-supported Entity(ies) the right to also use such licensed intellectual
property for other applications. 
 (h)    Pricing and Volume Commitments. The Company will make available in
Developing Countries all Products developed and commercialized pursuant to a Project (i) at or below the price set forth in the applicable TPP and (ii) in quantities meeting or exceeding those set forth in the applicable statement of work
(or other applicable global access agreements between the Foundation and the Company), provided that if the Fully Loaded Costs exceed the price set 

  
 12 













 
forth in the applicable TPP then the Company will make such Product available at the Fully Loaded Costs, unless the parties mutually agree otherwise. If a Product is to be sold at Fully Loaded
Costs in accordance with the foregoing provision, and the relevant buyer is an affiliate or any other related person (nahestehende Person) within the meaning of the German tax law of the Foundation, then the Company will make such Product
available to such relevant buyer at Fully Loaded Costs plus an arm’s-length markup of up to 10% (as applicable), provided, however, that (x) the competent German tax office responsible for the
taxation of the Company confirmed in a binding ruling (verbindliche Auskunft) pursuant to Sec. 89 para. 2 of the German Tax Code (Abgabenordnung) that a sale at Fully Loaded Costs without a profit markup would otherwise result in a
hidden profit distribution (verdeckte Gewinnausschüttung) under German tax law and the Company and the Foundation have, in good faith, agreed on a then applicable profit mark-up of up to 10% or
(y) a respective markup is applied with the Foundation’s prior written consent. Due to [***], it is likely that [***]. 

(i)    Build Out of Infectious Diseases Capabilities. Within [***] of the Closing of the Foundation Investment, the
Company will implement a plan for the build out of the Company’s infectious disease capabilities, excluding manufacturing, that is reasonably acceptable to the Foundation. Such plan will include [***] and further development of the Platform
Technology in order to enable the Company to conduct the HIV Project, the TB Project and any Additional Projects and achieve the Global Access Commitments. The Company will submit any subsequent proposed changes to such plan in advance to the
Foundation for approval (which approval shall not be unreasonably withheld or delayed). The Company will complete the build out according to the approved plan utilizing a portion of the Foundation Investment. In addition, the Company will provide
information to the Joint Steering Committee regarding the Company’s plans for the build out of manufacturing capabilities to produce infectious disease products as such plans become available. 

(j)    Joint Steering Committee. The Foundation and the Company will each designate three individuals who are
subject matter experts to be part of a joint steering committee (the “Joint Steering Committee”) that will provide a forum for discussion of the application of the Platform Technology and the progress of each of (i) the HIV
Project, (ii) the TB Project and (iii) all Additional Projects. The Joint Steering Committee will decide [***]. A decision by the Joint Steering Committee [***] shall not in any way limit or restrict the Foundation’s right to continue
further development of such Project or any other Project in accordance with Section 3(d). For the avoidance of doubt, the Joint Steering Committee shall have no authority to amend any statement of work with respect to a Project and any such
amendment requires the mutual agreement of the Foundation and the Company. 
 The Joint Steering Committee will meet at least once quarterly
via teleconference and at least once annually in-person. With the agreement of both the Foundation and the Company and subject to the execution of appropriate confidentiality agreements, third parties may be
invited from time to time to participate in certain Joint Steering Committee discussions. Decisions made at the Joint Steering Committee must be mutually agreed upon by each of a majority of the individuals designated by the Foundation and a
majority of the individuals designated by the Company; provided that if the Joint Steering Committee determines that a change is needed to the scope of work for the HIV Project or TB Project and such change would require a change to the


  
 13 













 
Platform Technology that the Company reasonably believes has a low probability of scientific or technical success or is reasonably likely to have a material adverse effect on the Company, then
such change will require the Company’s consent. Other than the decision described in the preceding sentence, [***], then such matter will be considered a Dispute and will be resolved in accordance with the dispute resolution procedure set forth
in Section 20. 
 (k)    Publication; Access to Data and Information. The Company will (in addition to
the publication requirements of any grant agreement with the Foundation): 
 (i)    publish the results and information
developed in connection with each Project within a reasonable period of time after such information or results are obtained, subject to reasonable delays or limitations on content of such publications that are necessary to protect intellectual
property and trade secrets covering the development and Platform Technology itself. All publications must be made in accordance with “open access” terms and conditions consistent with the Foundation’s Open Access Policy (available at:
http://www.gatesfoundation.org/ 
How-We-Work/ General-Information/ Open-Access-Policy), which may be
modified from time to time; and 
 (ii)    promptly provide to the Foundation from time to time, upon the
Foundation’s request and in a format that is acceptable to the Foundation, access to data and information regarding the Projects (including information necessary and sufficient to support the utilization of the Company’s Platform
Technology by partners who are collaborating on the Projects as set forth in the applicable statement of work (taking into account the need to protect the intellectual property of such Platform Technology)), the reasonably contemplated use of the
Platform Technology and Funded Developments for such Projects (taking into account the need to protect the intellectual property of such Platform Technology), and the considerations made by the Company with respect to accessibility, affordability
and cost effectiveness. 
 (l)    No Inconsistent Rights. The Company will not grant to a third-party any rights
or enter into any arrangements or agreements that would limit or restrict the Foundation’s or a Foundation-supported Entity’s ability to exercise its rights or the Company’s ability to perform its obligations under this Letter
Agreement (including the Global Health License and the Foundation’s right to require Additional Projects from the list of diseases set forth in Part A of Appendix C). The Foundation will not be required to take any action or enter into
any arrangement or agreement that would limit or restrict the Foundation’s ability to exercise its rights under this Letter Agreement. 

(m)    Global Health License. 

(i)    Global Health License. In connection with and relating to the Projects, the Company hereby grants the
Foundation, effective immediately, a worldwide, non-exclusive, non-terminable (subject to the terms of any relevant in-licenses),

using the licensed technology in order to develop and manufacture the relevant Products for the purpose of benefiting people in Developing Countries (including the right to reference regulatory filings related to the applicable Products). 

The technology transfer commitments described above apply to (i) the Funded Developments and (ii) Platform Technology; provided that
in the case of Platform Technology, the technology transfer commitments will only apply to Platform Technology that is required to exploit the applicable Product(s). In addition, the Company will have the right to object to the technology transfer

 4.    Survival of
Global Access Commitments. 
 In the event of (i) any Acquisition Transaction or (ii) the sale, exclusive license, or
other transfer of the Platform Technology or the Funded Developments, the Global Access Commitments will survive and be assumed in full by the purchaser, transferee, licensee, or acquirer either in a written agreement that is reasonably acceptable
to the Foundation or by operation of law (if the Company is the surviving entity in the Acquisition Transaction) and the Company will take all action necessary to ensure such assumption. Upon request, the Company will provide a redacted copy of the
underlying transaction documents to the Foundation evidencing such assumption (or continuation of the Company as the surviving entity). For clarity, notwithstanding anything to the contrary in this Letter Agreement, the Foundation’s rights
hereunder that exist on the date of the Acquisition Transaction or sale, exclusive license, or other transfer of the Platform Technology or the Funded Developments will not be terminated by such transaction.

(a)    The Foundation has a Withdrawal Right on the terms set forth in the Investment Agreement. The Company agrees that
the Withdrawal Right will remain in effect for so long as the Foundation holds any equity interests in the Company and if for any reason the Withdrawal Right is removed from the Investment Agreement or the Investment Agreement is amended or

payors in Developing Countries, in addition to the information that may be required under any grant agreements or other funding agreements. 

(c)    Without limiting the foregoing, at the Foundation’s written request, the Company will permit the Foundation or
its Representatives to inspect (at a reasonable time during regular office hours and in a way that does not unnecessarily interfere with the Company’s activities) the scientific records of the Company relating to each Project with due regard to
the reasonable need to protect trade secrets covering the Platform Technology and provided that the relevant persons performing the inspection are subject to reasonable confidentiality undertakings. Any such inspection must be notified at least ten
(10) Business Days in advance. In such notice, the Foundation shall specify in reasonable detail the scientific records it would like to inspect. The Foundation or its Representative will not be allowed to take any copies of any records

firm with copies of any records it may reasonably request in connection with such audit, request or inquiry, all at the 

  
 18 













 
Foundation’s expense. The Foundation may exercise its audit right under this Section 6(e) no more than once in any calendar year and no more than once for the same books and records;
provided that in the event the Company has previously been found to have been in breach the Foundation shall have the right to request an audit once per calendar quarter. In addition, any access shall be subject to reasonable confidentiality
undertakings to be assumed by the accounting firm towards the Company. 
 7.    Assignment. 

Notwithstanding anything in this Letter Agreement or any Investment Document to the contrary, the Foundation will have the right to assign
this Letter Agreement or transfer the Foundation Securities to (a) any successor charitable organization of the Foundation from time to time that is a tax-exempt organization as described in
Section 501(c)(3) of the Code, or (b) any tax-exempt organization as described in Section 501(c)(3) of the Code controlled by one or more trustees of the Foundation. The Foundation will notify
the Company of any such assignment, including the identity of the assignee, in a timely manner. Any further assignment of this Letter Agreement by the Foundation or the Company shall require the other party’s prior written consent which shall
not be unreasonably withheld or delayed. For the avoidance of doubt, if the Foundation transfers the Foundation Securities as permitted by this Section 7, the Foundation may assign to any such transferee all of its rights attached to such
Foundation Securities, including the Withdrawal Right.

within the meaning of Section 4945(d) of the Code. The proceeds of the Foundation Investment will not (a) be earmarked to be used for any activity, appearance or communication associated with the activities described in the foregoing
sentence, nor (b) be intended for the direct benefit, and will not benefit, any person having a personal or private interest in the Foundation, including descendants of the founders of the Foundation, or persons related to or controlled by,
directly or indirectly, such private interests. 
 For the avoidance of doubt, the Company will not use the funds received from the
Foundation to pay a dividend or redeem shares.

and specifically approved by the Foundation in its sole discretion. 
 11.    Anti-Corruption and Anti-Bribery.

relation to the execution of this Letter Agreement and the Investment Documents, provided that such press release has been approved in advance by the Foundation in writing. Any other announcement of the Foundation Investment by any other party,

Confidential Information by using the same degree of care, but no less than a reasonable degree of care, as the Receiving Party uses to protect its own confidential information. 

(d)    Nothing in this Letter Agreement will be interpreted as placing any obligation of confidentiality or non-use on the Receiving Party with respect to any information that the Receiving Party can demonstrate or provide reasonable evidence: (i) is in or enters the public domain through no fault of the Receiving
Party; (ii) is already in the possession of the Receiving Party prior to receipt of Confidential Information from the Disclosing Party without breach of any confidentiality restriction; (iii) is obtained by the Receiving Party from a third

 21

from any of the following: (i) analyzing the Confidential Information; (ii) comparing the Confidential Information to information in the possession of the Foundation; or (iii) making any grant or other investment to, or entering into

(g)    If at any time the Company or any of its Affiliates has a class of securities that is publicly traded, the Company
will notify the Foundation in writing when it provides the Foundation with any Confidential Information that the Company believes constitutes material non-public information which contains insider information

 (h)    The confidentiality provisions of this Section 13 with
respect to Confidential Information will survive for a period of [***], except in the case of (i) Confidential Information contained in third party agreements that have a term of confidentiality that extends beyond such period, in which case
the duties of non-use and non-disclosure of such Confidential Information shall survive for such period as stated in the applicable agreement and (ii) Confidential
Information that constitutes a trade secret under applicable law, in which case the non-use and non-disclosure of such Confidential Information shall survive for such

Agreement, all Confidential Information exchanged under such Confidentiality Agreement shall be exclusively governed by the terms of this Section 13. 

14.    Indemnification. 

The Company will indemnify, hold harmless, and defend the Foundation and its co-chairs, trustees,
directors, officers, employees, agents, and Representatives (collectively, the “Indemnitees”) from and against any and all third party causes of action, claims, suits, legal proceedings, judgments, settlements, damages, penalties,
losses, liabilities and costs (including reasonable attorneys’ fees and costs) (each a “Claim”) finally awarded to such third party by a court of competent jurisdiction against any of the Indemnitees or agreed to as part of a
monetary settlement of the Claim (in the case of a settlement, to which the Company has agreed in writing, such agreement not to be unreasonably withheld or delayed) and arising out of or relating to: (a) bodily injury, death or damage
(property or otherwise) caused by any wrongful acts or omissions of the Company, including any development or commercialization or distribution activities carried out by the Company which does not comply with applicable laws, regulations or rules in
connection therewith; or (b) any Claim that the Platform Technology, any Funded Development or any Product (but excluding, for the avoidance of doubt, any Claim relating to any modification 

  
 22 













 
or improvement made to any Product by or on behalf of the Foundation by a third-party other than the Company or its Affiliates (including by Development Partners, Manufacturing Partners and
sublicensees) outside or after the completion of a Project) infringes upon a patent, proprietary, or other intellectual property right of a third-party. The Foundation will give the Company prompt written notice of any Claim subject to
indemnification; provided, that the Foundation’s failure to promptly notify the Company will not affect the Company’s indemnification obligations except to the extent that the Foundation’s delay prejudices the Company’s ability
to defend the Claim. The Company will have sole control over the defense and settlement of each and every Claim, with counsel of its own choosing which is reasonably acceptable to the Foundation; provided, that the Company conducts the defense
actively and diligently at the sole cost and expense of the Company and provided further that the Company will not enter into any settlement that adversely affects any Indemnitee without the applicable Indemnitee’s prior written consent, such
consent not to be unreasonably withheld, conditioned or delayed. The Foundation will provide the Company, upon request, with reasonable cooperation in connection with the defense and settlement of the Claim. Subject to the Company’s rights
above to control the defense and settlement of Claims, the Foundation and any Indemnitee may, at its own expense, employ separate counsel to monitor and participate in the defense of any Claim under this Section 14. 

The parties will not be liable to each other for any indirect, incidental, consequential, or special damages (including lost revenues, lost
savings, or lost profits suffered by such other party) suffered by such other party arising under or in connection with this Letter Agreement, regardless of the form of action, whether in contract or tort, including negligence of any kind, whether
active or passive, and regardless of whether the party knew of the possibility that such damages could result; provided, that to the extent an Indemnitee is entitled to be indemnified hereunder for Claims of third parties and such third party has
been awarded indirect, incidental, consequential, reliance, or special damages (including lost revenues, lost savings, or lost profits), the Company’s indemnification obligations to the Indemnitee will extend to and include such third
party’s indirect, incidental, consequential, reliance, or special damages (including lost revenues, lost savings, or lost profits). The parties further agree that under no circumstances will any party be liable to the other party (or to
any Indemnitee) more than once for the same losses arising under or in connection with this Letter Agreement. 

15.    Insurance. 

The Company agrees to maintain insurance coverage sufficient to cover the activities, risks, and potential omissions in respect of the work
contemplated by or in connection with this Letter Agreement in accordance with generally-accepted industry standards and as required by law. 

16.    Compliance with Laws and Requirements; Responsibility.  

The Company will comply with all applicable laws, regulations, and rules and has not and will not knowingly infringe any patents of any third
party related to the Projects or this Letter Agreement. The Company has not and will not infringe, misappropriate or violate any copyrights, trade secrets, privacy or publicity rights, or other intellectual property rights (other than patents, which
are covered by the preceding sentence) of any third party related to the Projects or this Letter Agreement. The Company will conduct, control, manage, and monitor all work performed in connection with or as contemplated by this Letter Agreement
using the Foundation Investment in 

  
 23 













 
compliance with all applicable ethical, legal, regulatory, and safety requirements and obtain and maintain all necessary approvals, consents, and reviews for such activities. If any work
conducted by the Company in connection with or as contemplated by this Letter Agreement involves: 
 (a)    Protected

 (b)    children,
students, or vulnerable subjects, the Company will obtain any necessary consents and approvals unique to these subjects; or 

(c)    any trial involving human subjects, the Company will adhere to current Good Clinical Practice as defined by the
International Council on Harmonisation (ICH) E-6 Standards (or local regulations if more stringent) and will obtain applicable trial insurance. 

The Company will be solely responsible and liable for all activities related to the conduct of any work conducted by the Company as contemplated by or in
connection with this Letter Agreement. Any activities by the Foundation in reviewing documents and providing input or funding do not modify the Company’s responsibility, including responsibility for determining and complying with the provisions
of this Section 16. 
 17.    Specific Performance. 

The Company acknowledges and agrees that the Foundation would be damaged irreparably in the event that Sections 2, 3, 4, 5, 8, 9, 10, 11 or 12
of this Letter Agreement are not performed in accordance with their specific terms or otherwise are breached or violated. Accordingly, the Company agrees that, without posting bond or other undertaking, the Foundation will be entitled to an
injunction or injunctions to prevent breaches or violations of such provisions of this Letter Agreement and to enforce specifically this Letter Agreement and the terms and provisions hereof in any action instituted in any court having jurisdiction
over the Company and the matter in addition to any other remedy to which it may be entitled, at law or in equity. For clarity, nothing in this Letter Agreement shall limit the Foundation’s right to seek an injunction or injunctions to prevent
breaches or violations of any other provisions of this Letter Agreement, provided that it has posted bond or other security in accordance with applicable laws. The Company further agrees that, in the event of any action for specific performance in
respect of such breach or violation, it will not assert the defense that a remedy at law would be adequate. 

18.    Entire Agreement; Modification.  

The terms and conditions set forth in this Letter Agreement are in addition to the provisions stated in the other Investment Documents and the
terms and conditions of this Letter Agreement will prevail over any inconsistent provision in any other Investment Document and supersede any prior understandings and agreements, either oral or in writing, between the parties with respect to the
subject matter hereof. In addition, the terms and conditions in the body of this Agreement will prevail over any inconsistent provision in the HIV Project Statement of Work or TB Project Statement of Work. No change, modification or waiver of any
term or condition of this Letter Agreement will be valid unless it is in writing, it is signed by the party to be bound, and it expressly refers to this Letter Agreement.

 19.    Authority; Governing Law. 

Each of the signatories below covenants, represents and warrants that he, she or it had all authority necessary to execute this Letter
Agreement and that, on execution, this Letter Agreement will be fully binding and enforceable in accordance with its terms, and that no other consents or approvals of any other person or third parties are required or necessary for this Letter
Agreement to be so binding. This Letter Agreement will be governed by the laws of the State of New York, U.SA. irrespective of the principal place of business, residence or domicile of the parties hereto and without giving effect to otherwise
applicable principles of conflicts of law that would give effect to the laws of another jurisdiction. 
 20.    Dispute
Resolution 
 The parties will resolve any dispute, controversy or claim arising out of or relating to this Letter Agreement, or the
breach, termination or invalidity hereof (“Dispute”) in accordance with this Section 20. 

(a)    Designated Representatives; Escalation to CEOs. If a Dispute arises, the parties will each appoint a
designated representative whose task it will be to meet for the purpose of endeavoring to resolve such Dispute. The designated representatives shall meet as often as the parties reasonably deem necessary to discuss the problem in an effort to
resolve the Dispute without the necessity of any formal proceeding. If such representatives are unable to resolve the Dispute within twenty (20) Business Days after the Dispute is submitted to them, the Dispute shall be immediately referred by
written notice to the Chief Executive Officer of the Company and the President of Global Health (or any equivalent successor position) or the Chief Executive Officer of the Foundation. No settlement reached under this Section 20(a) shall be
binding on the parties unless reduced to a writing signed by the parties. The existence and substance of the negotiations pursuant to this Section 20(a) shall be considered confidential under this Letter Agreement, shall be treated as
compromise and settlement negotiations for purposes of Federal Rule of Evidence 408 and any comparable provision, and shall not be used by any party in any court, agency or tribunal in any country for any reason. If such officers are unable to
resolve such Dispute within twenty (20) Business Days after the Dispute is submitted to them, then the Dispute shall be submitted to arbitration in accordance with this Section 20. 

(b)    AAA Arbitration. 

(i)    Any Dispute that has not been resolved pursuant to Section 20(a) shall be referred to and finally resolved by
arbitration in New York, N.Y., U.S.A., pursuant to the Commercial Arbitration Rules of the American Arbitration Association. It is the intent of the parties that, barring extraordinary circumstances, the arbitration proceedings shall be concluded
within six (6) months from the date the arbitrator is confirmed. The parties may agree to extend this time limit or the arbitrator may do so in its discretion for a period of up to an additional three (3) months, if it determines that the
interest of justice so requires. The arbitrator shall use its best 

  
 25 













 
efforts to issue the final award or awards within such time period. Failure to adhere to this time limit shall not be a basis for challenging the award. 

(ii)    The arbitration shall be conducted by a single, neutral arbitrator who shall be experienced in the field of the
Dispute and shall have no ongoing business relationship with any party. Such arbitrator shall be selected by mutual agreement of the parties or, in the absence of such agreement, by the New York office of the American Arbitration Association. The
arbitrator may grant legal, equitable and monetary relief and shall award to the prevailing party such party’s costs and expenses incurred in connection with the arbitration and the collection of judgment, including reasonable attorneys’
fees. In no case, however, shall indirect, incidental, consequential, or special damages (including lost revenues, lost savings, or lost profits) be awarded by the arbitrator, except as permitted by Section 14. Judgment upon the award rendered
by the arbitrator shall be binding, final and non-appealable (absent manifest error) and may be entered and enforced in any court having jurisdiction thereof. The language used in the arbitration proceedings
shall be English. 
 (iii)    No information concerning a Dispute and any related arbitration, beyond the names of the
parties and the relief requested, may be unilaterally disclosed to a third party by any party unless required by law. Any documentary or other evidence given by a party or witness in the arbitration shall be treated as confidential by any party
whose access to such evidence arises exclusively as a result of its participation in the arbitration and shall not be disclosed to any third party (other than a witness or expert), except as may be required by law. 

(c)    Obligation to Continue Performance Pending Resolution of a Dispute. Both parties agree to continue
performing their obligations under this Letter Agreement pending the resolution of any Dispute that is being resolved hereunder unless and until such obligations are terminated or expire in accordance with the provisions of this Letter Agreement.

 (d)    Judicial Procedure. Notwithstanding the foregoing, and without waiting for the expiration of the time
periods set forth above, each party shall have the right to apply to any court of competent jurisdiction for appropriate interim or provisional relief, as necessary to protect its rights or property. Furthermore, nothing herein shall prevent the
parties from resorting to a court of competent jurisdiction in those instances where preliminary injunctive relief would be appropriate, pending final resolution of the Dispute through arbitration. Nothing in this Section 20 shall be construed
to prevent a party from instituting formal proceedings at any time to avoid the expiration of any statute of limitations period or to preserve a superior position with respect to other creditors. For the avoidance of doubt, to the extent this Letter
Agreement permits the parties to apply for relief to or institute a proceeding in a court of competent jurisdiction, nothing in this Letter Agreement or any other Investment Document will constitute a waiver of the right to a jury trial in such
proceeding. 
 21.    Severability. 

The invalidity or unenforceability of any provision of this Letter Agreement will in no way affect the validity or enforceability of any other
provision. 

  
 26 













 22.    Counterparts. 

This Letter Agreement may be executed in one or more counterparts, each of which will be deemed an original, but all of which will be deemed
to be and constitute one and the same instrument. 
 23.    Construction. 

Section headings are not to be considered part of this Letter Agreement, are included solely for convenience, are not intended to be full or
accurate descriptions of the content thereof and will not affect the construction of this Letter Agreement. The words “include,” “includes” and “including” will be considered to be followed by the words “without
limitation”.
