2. Charitable Purposes and Use of Funds; Foundation Technology Access 

(a) The Foundation is making the Foundation Investment as a “program-related investment” within the meaning of Section 4944(c)
of the Code. The Foundation’s primary purpose in making the Foundation Investment is to further significantly the accomplishment of the Foundation’s charitable purposes, including the relief of the poor, distressed and underprivileged, the
advancement of science, and the promotion of health by seeking to (i) address global health challenges that disproportionately impact developing countries, and (ii) increase the access of poor and distressed individuals and families in
developing countries to life-saving and other important vaccines, drugs and technologies that may assist in the prevention, treatment and detection of the Target Diseases and Conditions (collectively, the “Charitability
Requirements”). 
 (b) The Foundation is making this investment to secure Global Access rights to new, low-cost vaccines and drugs developed (in whole or in part) through the use of the Company’s Platform Technology and for the Target Diseases and Conditions. The Foundation believes the Platform Technology has
potential application in the Target Diseases and Conditions and, therefore, the Platform Technology (and any improvements and developments thereto), in conjunction with the Global Access Commitments described below, will achieve the Charitability
Requirements. 

  
 4 













 (c) Use of Funds. The Company will use the proceeds from the Foundation Investment
solely (1) to further develop and leverage the Company’s Platform Technology to create Funded Developments that are reasonably expected to comprise or result in affordable drugs, therapeutics, diagnostics, prophylactics or other health
products, services and interventions for the treatment, prevention and/or amelioration of Target Diseases and Conditions for people in Developing Countries in accordance with Global Access and (2) to conduct the HIV Program and the TB Program.
At least fifty percent (50%) of the Foundation Investment will be used to conduct the HIV Program and the TB Program. Specific deliverables and objectives with respect to development of the Platform Technology and the performance of the HIV Program
and TB Program are set forth below. For the avoidance of doubt, (i) use by the Company of the proceeds from the Foundation Investment for [***] the HIV Program and the TB Program or the development of Funded Developments (including allocation
of reasonable overhead expenses) shall be deemed to be funds used to conduct the HIV Program, TB Program and/or such Funded Development, as applicable, in compliance with this Section 2(c); and (ii) the Company is [***]. 

3. Global Access Commitments  

In furtherance of the Charitability Requirements and Global Access, the Company agrees to the following (collectively “Global
Access Commitments”): 
 (a) Development of Platform Technology; Global Health Projects; Reports. 

(i) The Company will use Reasonable Efforts to complete the Platform Technology objectives set forth on Appendix 3 and to utilize the Platform
Technology to advance the HIV Program through the completion of Phase 1 clinical trials on the HIV Product and to advance the TB Program through the completion of IND-enabling studies on the TB Product, in
each case, in furtherance of the Foundation’s charitable purpose. The Company agrees that after completion of the requirements in the preceding sentence (or at such earlier time as the Foundation may elect), the Foundation may request that the
Company continue further development of the HIV Product and/or TB Product, including through product launch of a final product as further described in Section 3(a)(iii) below. 

(ii) In addition to the HIV Program and the TB Program, if requested by the Foundation, the Company will work together with the Foundation on
one additional Global Health Project based on the Platform Technology for Target Diseases and Conditions as mutually agreed by the parties. The Company and the Foundation can work on more than one additional Global Health Project if they mutually
agree to do so. 
 (iii) If the Foundation requests that the Company continue further development of the HIV Product and/or TB Product, or
the Foundation requests an additional Global Health Project pursuant to Section 3(a)(ii), any such further development or Global Health Project will be documented in a definitive agreement between the Foundation (or a Foundation-supported
Entity) and the Company and project plan, which may include [***]. The Foundation and the Company will [***]. The specific level of funding responsibilities for the additional work will be decided as mutually agreed in good faith in writing by the
parties. The Foundation shall be [***]. Any additional work may be divided into milestones or phases. The Foundation will have the right, at its sole discretion, to continue providing funding (directly or through a Foundation-supported Entity) to
advance the HIV Product, TB Product and/or any product developed in connection with any other Global Health Project through to product launch of a final product for the purpose of enabling Global Access. In the event the parties [***].

 In addition, if the HIV Product, TB Product and/or any products developed under the
additional Global Health Project proceeds to [***], the Company will work in good faith with the Foundation to develop and execute [***] that will enable the Company to [***]. The [***] will be determined by the Foundation and the Company based
upon [***]. The price of such products in Developing Countries will be such that the products are affordable to the Foundation’s target beneficiaries in the Developing Countries, but in no case will the price exceed COGS plus
[***]. The [***]. The specific level of funding responsibilities for such plan will be decided as mutually agreed in good faith in writing by the parties. The Foundation shall be [***]. The Foundation will have the right to inspect the
Company’s records pursuant to Section 7 herein, in order to [***] for so long as is necessary to ensure compliance with this Section 3(a)(iii). 

(iv) On a [***] basis, the Company will meet with representatives from the Foundation to discuss the progress of the HIV Program and TB
Program and any other Global Health Project then in process. Such meetings will be in person if so requested by the Company or the Foundation and otherwise may be held by videoconference or teleconference. From time to time, as may be agreed upon by
the parties, these discussions may [***]. In addition, at the [***], the Company shall provide the Foundation with an HIV Product Report and a TB Product Report (as defined below). The Company agrees to provide written reports detailing (A) the
current status of the HIV Program in a form to be agreed upon by the Company and the Foundation (“HIV Program Report”) and (B) the current status of the TB Program in a form to be agreed upon by the Company and the Foundation
(“TB Program Report”). Each of the HIV Product Report and the TB Product Report will [***]. In addition, each report will [***] for the applicable program. If the parties elect to collaborate with respect to any other Global Health
Project other than the HIV Program or the TB Program, the Company shall provide [***] written reports detailing the progress of such other Global Health Project and the parties shall mutually agree on the applicable information to be included in
such report(s). 
 (v) The Company will ensure that any Funded Developments that are applicable for the treatment, prevention or amelioration
of any Target Diseases and Conditions and all products developed using the Platform Technology that arise from or relate to a Global Health Project will be made available and accessible at an affordable price to people most in need within Developing
Countries, which price will not exceed COGS plus [***]. The Foundation will have the right to inspect the Company’s records pursuant to Section 7 in order to [***] for so long as is necessary to ensure compliance with this
Section 3(a)(v). 
 (b) Coordination with Foundation-supported Entities. The Company acknowledges that the Foundation is
currently funding research and development projects at various Foundation-supported Entities that are relevant to the development of the HIV Product and the TB Product, including [***], and their respective Affiliates. In connection with the work to
be performed on the Platform Technology, HIV Program and TB Program pursuant to this Letter Agreement, the Company shall cooperate with these entities in good faith to coordinate its development efforts on the HIV Program and TB Program with these
entities. This process may include [***] and [***]. While the coordination, acquisition of rights and completion of [***] referred to in this paragraph are the responsibility of the Company to effect, the Foundation will assist in these efforts, in
particular those that relate to work funded by the Foundation. Nothing in this Letter Agreement constitutes a commitment by the Foundation to make any grants to the Company or a Foundation-supported Entity and the decision to proceed with a grant
will be made solely at the Foundation’s discretion. For clarity, no provision of this Letter Agreement will limit or restrict the Foundation’s rights pursuant to any grant agreement or other contract with any third party.

 (c) [***]. 

(d) Compliance with Intellectual Property Rights. The Company represents and warrants that, as of the Effective Date, to the actual
knowledge of the Company, the Company has all necessary rights to the Platform Technology, the HIV Product and the TB Product (including all rights in any patents, copyrights, trademarks, trade secrets, data, confidential information, know-how or other intellectual property or proprietary right) required to fulfill the Company’s obligations under this Letter Agreement and to grant the licenses expressly granted by the Company hereunder. The
Company covenants that in the performance of the HIV Program, TB Program and any other Global Health Project, the Company will [***] the Platform Technology, the HIV Product, the TB Product and any product developed in connection with any other
Global Health Project (including all rights in any patents, copyrights, trademarks, trade secrets, data, confidential information, know-how or other intellectual property or proprietary right) required to
fulfill the Company’s obligations under this Letter Agreement and any other agreement between the Foundation and the Company related to the development of such products and to grant the licenses expressly granted by the Company hereunder. In
connection with the Funded Developments, the Company shall comply with all applicable laws and regulations and shall not knowingly violate third party intellectual property. 

(e) Publication. The Company will use [***] to: 

(i) Publish the scientific results and information developed in connection with each Global Health Project within a reasonable period of time
after the information or results are obtained, with due regard to reasonable delays or limitations on content of these publications that are necessary to protect intellectual property. 

(ii) [***]. 
 (iii) [***]. 

(iv) If the Company seeks publication of Funded Developments in a peer-reviewed journal, such
publication must be under “open access” terms and conditions consistent with the Foundation’s Open Access Policy attached hereto as Appendix 6.  

(f) Non-Exclusive License. 

(i) Solely upon the occurrence, if any, of a License Trigger, and only in such event, the Company hereby grants the Foundation a [***];
provided that, in each case, the license to the Funded Developments and the background technology is limited [***]. The Foundation and the Company agree and acknowledge that in order to achieve Global Access and make the Funded Developments
available and accessible in Developing Countries, certain activities may be required to occur in one or more developed countries, like manufacture, distribution, or sale (such as to an entity procuring a product for use in Developing Countries).
Accordingly, the license to the Foundation shall [***]. The definitive agreements with respect to any additional Global Health Project will include, to the extent applicable, license provisions with respect to the Global Health Project consistent
with the license provisions set forth in this Letter Agreement. For the avoidance of doubt, to the extent any additional fees, royalties, milestones or other payments are payable to any third party solely as a result of the Company’s grant of,
or the Foundation’s exercise of, the license granted pursuant to this paragraph, the Foundation shall be responsible for all such payments to the extent such fees, royalties, milestones or other payments are for the benefit of the Foundation or
a Foundation-supported Entity and the payment of such fees, royalties, milestones or other payments would not constitute a taxable expenditure under Treasury Regulation 53.4945-6(a)-(b); provided, that the
Company may renounce any non-incidental benefit received by the Company related thereto and, in such event, the Foundation shall pay the full amount of such additional fees, royalties, milestones or other
payments. 

  
 7 













 (ii) License Triggers. Notwithstanding the forgoing license grants, the Foundation
shall only exercise its rights under the license (including its sublicensing rights) during the pendency of the occurrence of at least one of the following, and, in any event, not prior to the end of the [***] period set forth in the last paragraph
of this Section 3(f)(ii) (each a “License Trigger”): 
 (A) a Charitability Default; 

(B) the Company either: (i) indicates in writing that it is unwilling or unable to commence, proceed or continue with development of the
HIV Product, TB Product or any other Global Health Project previously agreed to by the Company, or (ii) fails to commence, proceed or continue with development of the HIV Product, TB Product or such other Global Health Project within [***] of
receipt of a written notice from the Foundation [***]. For the avoidance of doubt, a License Trigger shall not be deemed to have occurred pursuant to this Section 3(f)(ii)(B) if the HIV Program, the TB Program or any other Global Health Project
is [***]; or 
 (C) the Company institutes any bankruptcy, insolvency, reorganization for the benefit of creditors, dissolution, liquidation
or similar proceeding relating to it under the laws of any jurisdiction or any such proceeding is instituted against the Company. 
 If either the Foundation
or the Company becomes aware of a License Trigger it will promptly notify the other party in writing of the occurrence of a License Trigger, setting forth in reasonable detail the reasons therefor. If the Company disputes the Foundation’s
belief that a License Trigger has occurred, the Company and the Foundation will [***], after which time, such dispute will be decided in accordance with the dispute resolution procedure described in Section 18 herein. If the parties have not
resolved such dispute prior to the end of the License Negotiation Period, then during the pendency of the dispute resolution procedure described in Section 18 herein, the Foundation may exercise the license pursuant to Section 3(f)(i) (and
the dispute resolution procedure shall continue notwithstanding the exercise of such license grant), provided that: [***]; (y) until such time as the dispute is finally decided against the Company pursuant to the dispute resolution procedure
described in Section 18: [***]; and (z) if the dispute is finally decided in favor of the Company pursuant to the dispute resolution procedure described in Section 18: [***]. 

(g) Modifications. The principal purpose of the license granted to the Foundation is to ensure that Global Access is achieved as rapidly
as reasonably practicable. The parties acknowledge that product launch and/or distribution of Company products and processes for the benefit of end users in Developing Countries may require worldwide commercialization and /or distribution rights to
be maintained by a single party. During the implementation of the Global Health Projects, the Company may demonstrate, on a case-by-case basis, to the satisfaction of
the Foundation that Global Access can best be achieved in a particular case without such a license. In such a case, the Foundation and the Company may modify or terminate in whole or in part the forgoing license as mutually agreed as reflected in a
signed writing. 
 (h) Cooperation; Technology Transfer. The Company agrees to use Reasonable Efforts to enable the Foundation or its
sublicensees to exercise their rights hereunder, which efforts shall include, as reasonably required, [***]. For the avoidance of doubt, the obligations under this paragraph shall not require the Company to incur additional expenses or to make
additional payments to [***], unless the Foundation or a Foundation-supported Entity is willing to pay such additional expenses or payments. 

  
 8 













 In connection with the exercise of the foregoing licenses under Section 3(h), the Company’s use of
Reasonable Efforts shall include, as reasonably required: [***]. The Foundation will pay all reasonable third party costs and expenses incurred by the Company as a result of complying with the preceding sentence, if any. 

(i) Duration. The Global Access Commitments will commence upon the initial closing of the Foundation Investment and be ongoing and will
continue for as long as the Foundation continues to be a charitable entity (including following the exercise of the Withdrawal Right) except that the Company’s obligation to accept one additional Global Health Project will terminate [***]
following the initial closing of the Foundation Investment. For clarity, the Global Access Commitments will continue as to any Funded Developments that are assigned, sold, transferred or exclusively licensed to a third party. 

4. Third Party Costs. 
 Except as
otherwise provided in this Letter Agreement, the Company shall be responsible for all costs associated with its technology and intellectual property owned, controlled or licensed-in. The Company shall use
Reasonable Efforts to ensure that any intellectual property and technology it hereafter owns, controls or in-licenses is available for potential sublicensing to the Foundation consistent with the terms of this
Letter Agreement. Without limiting the foregoing, the Company shall use Reasonable Efforts to [***]. 
 5. Obligations in the Event of a Sale of the
Platform Technology or Company; Preservation of Global Access Commitments. 
 In the event that all or substantially all of the
Company’s assets, the Platform Technology owned or controlled by the Company, or the Funded Developments are transferred to, exclusively licensed to, sold or acquired by a third party, the Company will require the purchaser, transferee,
licensee or acquirer to assume the Global Access Commitments in a written agreement that is reasonably acceptable to the Foundation. The Company will not grant to a third party any rights or enter into any arrangements or agreements (including any
amendment or modification to the Existing Agreements) that would limit or restrict the Foundation’s rights pursuant to the Global Access Commitments, including the Foundation’s right to enter into Global Health Projects with the Company,
unless such third-party expressly assumes such Global Access Commitments to the reasonable satisfaction of the Foundation. Consistent with the preceding sentence, the Company covenants that if the Company decides to no longer pursue the TomegaVax
technology and is required to negotiate in good faith with the individuals who are parties to the Existing Agreements (collectively, the “Consultants”) to find an alternative manner in which the Consultants can continue to develop
the TomegaVax technology, the Company will not enter into any exclusive arrangement with the Consultants or grant to the Consultants any rights or enter into any arrangements or agreements that would limit or restrict the Foundation’s rights
pursuant to the Global Access Commitments. For clarity, notwithstanding anything to the contrary in this Letter Agreement, the Foundation’s rights hereunder which exist on the date of the transfer, sale or acquisition of the Company’s
Platform Technology, Funded Developments, or other assets to or by a third party shall not be terminated by such transfer, sale or acquisition. 
 6.
Withdrawal Right. 
 (a) The Withdrawal Right described and defined in this Section 6 will be triggered only as a result of a
Charitability Default. For the avoidance of doubt, the Withdrawal Right and the Charitability Default will not be triggered by [***], so long as the Company has not breached its obligations under this Letter Agreement. 

  
 9 













 (b) A “Charitability Default” will occur if the Company either
(i) fails to comply, in any material respect, with the restrictions in Sections 2(c) and 10 of this Letter Agreement on the use of funds from the Foundation Investment or the other related U.S. legal obligations set forth in this Letter
Agreement, including without limitation the requirements set forth in Sections 7, 12, and 13 below, or (ii) is in material breach of the Global Access Commitments. Each party agrees to promptly notify the other party in writing if it has
knowledge of any Charitability Default and the Company shall thereafter provide to the Foundation a proposed strategy to remedy the Charitability Default. 

(c) If the Company fails to cure the Charitability Default within [***] of receipt of the above described notice (provided that solely for
purposes of this Section 6 in the event the Company disputes that a Charitability Default has occurred, such [***] period will commence upon a decision that a Charitability Default has occurred pursuant to the dispute resolution process
described in Section 18); and the Foundation holds any securities of the Company issued in connection with the Foundation Investment, including securities issued in respect of or upon conversion or exercise of such securities (collectively, the
“Foundation Stock”), the Company shall have the obligation, if requested by the Foundation, to redeem or arrange for a third party to purchase all (but not less than all) of the Foundation Stock (the “Withdrawal
Right”), provided that any such redemption or repurchase shall be made only to the extent permitted by applicable law concerning distributions to holders of equity interests. Without limiting the foregoing, if the Company is unable to
redeem all of the Foundation Stock, and no third party purchases the Foundation Stock, then the Company shall use commercially reasonable efforts to effect the Withdrawal Right, consistent with the Code and applicable law, as soon as practicable
thereafter, provided that to the extent any redemption of the Foundation Stock pursuant to this Section 6(c) would have [***]. For the avoidance of doubt, the Foundation shall cease to be a stockholder for all purposes effective as of the date
such Foundation Stock is redeemed and, thereafter, the sole right of the Foundation with respect to its ownership of Foundation Stock shall be to receive such redemption payment. During the period when the Company is unable to exercise its
obligation to redeem or find a purchaser of the Foundation Stock, the Company shall [***] until such time as the Company has fulfilled the Withdrawal Right with respect to all of the Foundation Stock). 

(d) For redemption or purchase by a third party pursuant to Section 6(c), Foundation Stock shall be valued at the greater of (i) the
original purchase price attributable to such shares plus a 5% compounding interest rate per annum through the date of the completion of the redemption or third-party sale, as applicable or, at the option of the Foundation, (ii) the then current
fair market value as determined by a mutually agreed upon (such agreement not to be unreasonably withheld) independent third-party appraiser. 

(e) If the Foundation Stock is sold or redeemed due to a Charitability Default, the Foundation will have a look back right by which, in the
event that (i) the Company consummates a Sale Transaction or (B) the closing of a firmly underwritten public offering (“Public Offering”) of shares of common stock of the Company pursuant to a registration statement under
the Securities Act, representing a per share valuation for the Company in excess of 200% of the valuation used for the sale or redemption of the Foundation Stock from the Foundation, and (ii) the Company signed a binding letter of intent or
binding term sheet or entered into any definitive agreement (each, a “Binding Agreement”) with respect to such Sale Transaction or filed the preliminary prospectus (other than any free-writing prospectus) in connection with such
Public Offering, as applicable, at any time prior to the six (6) month anniversary of the first date that any of the Foundation Stock was redeemed or sold, then the Foundation will receive compensation equal to the excess of what it would have
received in such transaction if it still held the Foundation Stock at the time of such Sale Transaction or Public Offering over what it actually received in the sale or redemption of the Foundation Stock; provided that such Sale Transaction or
Public Offering actually closes prior to the first anniversary of the first date that any of the Foundation Stock was redeemed or sold. For clarity, if the Company does not enter into any Binding Agreement or file its preliminary prospectus, as
applicable, until after the six (6) month anniversary of the initial sale or redemption date of the Foundation Stock, then the Foundation’s look-back right set forth in this Section 6(e) will terminate and be of no further force and
effect.

 7. Required Reporting; Audit Rights  

In addition to any reports required to be delivered to the Foundation pursuant to the Investment Documents, the Company shall furnish, or cause
to be furnished, to the Foundation the following reports and certifications: 
 (a) Within [***] after the end of each of the Company’s
fiscal years during which the Foundation owns any securities in the Company or any loans from the Foundation to the Company are outstanding, a certificate from the Company signed by an officer or director of the Company and substantially in the form
attached to this Letter Agreement as Appendix 4, certifying that the requirements of the Foundation Investment set forth in this Letter Agreement were met during the immediately preceding fiscal year, describing the use of the proceeds of the
Foundation Investment and summarizing the Company’s progress toward achieving the Global Access Commitments; 
 (b) Within [***] days
after the end of the Company’s fiscal year during which the Foundation ceases to own any securities in the Company or all loans from the Foundation to the Company cease to be outstanding, a certificate from the Company signed by an officer or
director of the Company and substantially in the form attached to this Letter Agreement as Appendix 5, certifying that the requirements of the Foundation Investment set forth in this Letter Agreement were met during the term of the Foundation
Investment, describing the use of the proceeds of the Foundation Investment and summarizing the Company’s progress toward achieving the Global Access Commitments; 

(c) Any other information respecting the operations, activities and financial condition of the Company as the Foundation may from time to time
reasonably request to discharge any expenditure responsibility, within the meaning of Sections 4945(d)(4) and 4945(h) of the Code, of the Foundation with respect to the Foundation Investment, and to otherwise monitor the charitable benefits intended
to be served by the Foundation Investment; provided, that the Foundation will reimburse the Company for any reasonable third-party expenses incurred by the Company in order to prepare any information the Company is required to prepare solely as a
result of this Section 7(c); and 
 (d) Full and complete financial reports of the type ordinarily required by commercial investors
under similar circumstances to the extent required pursuant to Treasury Regulation 53.4945-5(b)(4). 

(e) The Company will maintain books and records adequate to provide information ordinarily required by commercial investors under similar
circumstances, including copies of any reports submitted to the Foundation related to each Global Health Project. The Company will retain such books, records and reports for [***] and will make such books, records and reports available at reasonable
times to enable the Foundation to [***]. 
 (f) The Company will permit employees or agents of the Foundation at any reasonable time and upon
reasonable prior notice, during normal business hours, to examine or audit the Company’s books and accounts of record and to make copies and memoranda of the same, in each case, at the Foundation’s expense, to audit the Company’s
compliance with the use of the Foundation’s funds; provided that the Foundation will not conduct such an examination more frequently than once per year unless: (i) required due to an audit, request or inquiry of the Foundation by the
Internal Revenue Service; or (ii) the Foundation has a reasonable belief that a Charitability Default has occurred. If the Company 

  
 11 













 
maintains any records (including without limitation computer generated records and computer software programs for the generation of such records) in the possession of a third party, the Company,
upon request of the Foundation, will notify such party to permit the Foundation access to such records at reasonable times and to provide the Foundation with copies of any records it may reasonably request in connection with such audit, request or
inquiry, all at the Foundation’s expense. 
 8. Corporate Governance. 

(a) The Company agrees that [***]. The observer shall be entitled to attend and speak at all meetings of the Company Board and receive notice
of all such meetings and copies of all Company Board and committee materials as if the observer were a director but shall not be entitled to vote on any matters voted on by the Company Board, either at a meeting or by written consent.
Notwithstanding the foregoing, the Company reserves the right to exclude such observer from access to a meeting of the Company Board or any committee thereof, any portion thereof, or to any material if the Company believes such exclusion is
reasonably necessary [***]. To protect further disclosure of any information received by such observer, as a condition to attending any meetings of the Company Board or the receipt of any information as provided in this Section 8(a), the
Company shall have the right to require the observer to execute a separate confidentiality agreement reasonably acceptable to the Foundation and such observer which provides, among other things, that the observer shall agree to hold in confidence
and trust and to act in a fiduciary manner with respect to all information provided to the observer in such capacity. This Section 8(a) shall terminate and be of no further force or effect immediately prior to the earliest of [***]. 

(b) The Company shall not use any proceeds of the Foundation Investment for the following matters without the Foundation’s approval:
(i) a payment of dividends, or (ii) any redemption of shares (excluding repurchases of stock from former employees, officers, directors, consultants or other persons who performed services for the Company or any subsidiary in connection
with the cessation of such employment or service). 
 9. Assignment. 

Notwithstanding anything in this Letter Agreement to the contrary, (a) the Foundation will have the right to assign this Letter Agreement
(in whole but not in part) or transfer the Foundation Stock to (i) any successor charitable organization of the Foundation from time to time that is a tax exempt organization as described in Section 50l(c)(3) of the Code, or (ii) any
tax exempt organization as described in Section 50l(c)(3) of the Code controlled by one or more trustees of the Foundation; and (b) the Company will have the right to assign this Letter Agreement (in whole but not in part) without the
consent of the Foundation or any other person: (x) in connection with a Sale Transaction, subject to the terms of Section 5; and (y) to any Affiliate of the Company (provided, that: (A) such Affiliate has adequate financial
resources to perform the Company’s obligations under this Letter Agreement; and (B) in the event any such Affiliate ceases to have adequate financial resources to perform the Company’s obligations under this Letter Agreement, the
Company shall be secondarily liable for such obligations). Except as provided in the preceding sentence, neither party shall have the right to assign (whether by merger, sale of stock, sale or license of assets, or otherwise) this Letter Agreement
without the prior written consent of the other party, which consent will not be unreasonably withheld. The Foundation or the Company, as applicable, will notify the other party of any such proposed assignment, including the identity of the assignee,
in a timely manner. For the avoidance of doubt, if the Foundation transfers the Foundation Stock as permitted by this Section 9, the Foundation may assign to any such transferee all of its rights attached to such Foundation Stock, including the
Withdrawal Right. 

  
 12 













 10. Prohibited Uses. 

The Company shall not expend any proceeds of the Foundation Investment to carry on propaganda or otherwise to attempt to influence legislation,
to influence the outcome of any specific public election or to carry on, directly or indirectly, any voter registration drive, or to participate or intervene in any political campaign on behalf of or in opposition to any candidate for public office
within the meaning of Section 4945(d) of the Code. The proceeds of the Foundation Investment shall not (a) be earmarked to be used for any activity, appearance or communication associated with the activities described in the foregoing
sentence, or (b) be intended for the direct benefit, and will not directly benefit, any person actually known to the Company (including after being identified to the Company by the Foundation) as having a personal or private interest in the
Foundation, including without limitation, descendants of the founders of the Foundation, or persons related to or controlled by, directly or indirectly, such persons; provided, that in no event shall the Company (or any of its officers, directors,
employees, agents or representatives) have any duty of inquiry with respect to the foregoing. 
 For the avoidance of doubt, except as
otherwise expressly permitted in this Letter Agreement, the Company will not use the Foundation Investment to pay a dividend or redeem shares. 
 11.
Disqualified Person.  
 The Company represents and warrants to the Foundation that neither the Company nor, to the actual
knowledge of the Company, any shareholder of the Company is a “disqualified person” with respect to the Foundation (as the term “disqualified person” is defined in Section 4946(a) of the Code). The Foundation represents and
warrants to the Company that the Foundation does not, and one or more disqualified persons with respect to the Foundation do not, directly or indirectly, control the Company. 

12. Anti-Terrorism. 
 The Company
will not use any portion of the Foundation Investment, directly or indirectly, in support of activities (a) prohibited by U.S. laws related to combatting terrorism; (b) with persons on the List of Specially Designated Nationals
(www.treasury.gov/sdn) or entities owned or controlled by such persons; or (c) with countries or territories against which the U.S. maintains comprehensive sanctions (currently, Cuba, Iran, (North) Sudan, Syria, North Korea, and the Crimean
Region of Ukraine), unless such activities are fully authorized by the U.S. government under applicable law and specifically approved by the Foundation in its sole discretion. 

13. Anti-Corruption and Anti-Bribery. 

The Company will not offer or provide money, gifts, or any other things of value directly or indirectly to anyone in order to improperly
influence any act or decision relating to the Foundation or any activities contemplated by this Letter Agreement or the Company’s organizational documents (e.g., certificate of incorporation), including by assisting any party to secure an
unlawful advantage. Training and information on compliance with these requirements are available at www.learnfoundationlaw.org. 
 14. Public Reports;
Use of Name. 
 The Company and the Foundation shall cooperate with respect to the first public announcement of this Letter Agreement
and/or any of the matters contemplated hereby which, in any event, shall not occur prior to the first public announcement of the existence of the Company (excluding any filing by the Company with a governmental entity) (the “Company
Launch”). The timing of the Company Launch shall be in the sole discretion of the Company. Prior to the Company Launch, (a) neither party shall issue any press release or make any other public disclosure of the terms or existence of
this Letter Agreement 

  
 13 













 
without the prior written consent of the other party; and (b) the Foundation shall not make any public announcement which reveals or otherwise refers to the existence of the Company;
provided that nothing in this Letter Agreement will limit or restrict a party’s right to disclose information to the Internal Revenue Service or any other governmental authority to the extent required by applicable law or regulation. After the
Company Launch, each of the Foundation and the Company may include information on this investment in its periodic public reports and may make the investment public at any time on its web page and as part of press releases, public reports, speeches,
newsletters and other public documents. Any announcement of the Foundation Investment by any third party will require the prior written approval of the Foundation and the Company. Other than with respect to the foregoing rights, each party
shall also obtain the other party’s prior written approval for any other use of the other party’s name or logo in any respect; provided, that each party may use the other party’s name for any uses that have been previously approved in
writing by such party. Notwithstanding the foregoing, each party’s name and logo will not be used by the other party in any manner to market, sell or otherwise promote the Company, its products, services and/or business. 

15. Indemnification. 
 (a)
Company Indemnity. The Company will indemnify, hold harmless, and defend the Foundation and its co-chairs, trustees, directors, officers, employees and representatives (collectively, the
“Foundation Indemnitees”) from and against any and all judgments, settlements, damages, penalties, losses, liabilities and costs (including reasonable attorneys’ fees and costs) as a result of third party causes of
action, claims, suits, or legal proceedings (each a “Claim”) finally awarded to such third party by a court of competent jurisdiction against any of the Foundation Indemnitees or agreed to as part of a monetary settlement of the
Claim and arising out of or relating to: (a) bodily injury, death or property damage caused by the activities or omissions of the Company, including any development, product launch or commercialization activities carried out by the Company
(including any failure to comply with applicable laws, regulations or rules in connection therewith), or by any Company product; or (b) any Claim that the Platform Technology, any Funded Development or any Company product 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 pursuant to this Section 15(a); 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 subject to indemnification pursuant to this Section 15(a), 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, in any material respect, any Foundation Indemnitee without the applicable Foundation
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 Foundation Indemnitee may, at its own expense, employ separate counsel to monitor and participate in the defense of any Claim
under this Section 15(a). For the avoidance of doubt, the Company shall have no liability to the Foundation or any obligation to indemnify the Foundation pursuant to this Section 15(a) to the extent such claim arises out of the
Foundation’s fraud, negligence or willful misconduct. 
 (b) 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 

  
 14 













 
to the extent a Foundation 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 Foundation Indemnitee shall 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 Foundation Indemnitee) more than once for the same losses
arising under or in connection with this Letter Agreement. 
 16. Entire Agreement; Modification.  

The terms and conditions set forth in this Letter Agreement are in addition to the provisions stated in the Investment Documents and the terms
and conditions of this Letter Agreement shall prevail over any inconsistent provision in any Investment Document, solely to the extent of such inconsistency. No change, modification or waiver of any term or condition of this Letter Agreement shall
be valid unless it is in writing, it is signed by the party to be bound, and it expressly refers to this Letter Agreement. 
 17. 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 shall be governed by the laws of the State of Washington, excluding provisions of conflicts of laws which would result in the application of the law of any other jurisdiction. 

18. Dispute Resolution. 
 (a)
Except as specifically otherwise provided herein, any disagreement or dispute between the parties arising out of or related to this Letter Agreement (a “Dispute”), shall be resolved in the manner provided in this Section 18.
Should there develop a Dispute, such Dispute shall be resolved in the order of preference of Sections 18(b) - (d) below. 
 (b) [***] 

(c) [***] 
 (d) [***] 

(e) [***] 
 (f) [***] 

(g) [***] 
 (h) [***] 

(i) 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. 

  
 15 













 (j) 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 18 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. 
 19. Confidential Information. 

(a) Except to the extent expressly authorized by this Letter Agreement or otherwise agreed in writing, the receiving party (the
“Receiving Party”) shall keep confidential and shall not publish or otherwise disclose or use for any purpose other than as provided for in this Letter Agreement any Confidential Information of the other party (the
“Disclosing Party”). Notwithstanding the foregoing, Confidential Information shall not include any information to the extent that: (i) it can be established by written documentation of the Receiving Party that such information
is generally available to the public other than through unauthorized disclosure thereof by the Receiving Party; (ii) such information is lawfully acquired from other sources which are not prohibited from disclosing such information, and without
obligation of confidentiality; (iii) such information is approved for disclosure by the consent of the Disclosing Party; or (iv) such information is independently developed by the Receiving Party without use or reference to the Disclosing
Party’s Confidential Information. 
 (b) 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 Confidential Information that the Receiving Party is required to disclose pursuant to law, regulation or court order. In the event that
Confidential Information is required to be disclosed by the Receiving Party pursuant to law, regulation or court order, the Receiving Party shall make all reasonable efforts to notify the Disclosing Party of such requirement, in order to allow the
Disclosing Party to seek a protective order or seek confidential treatment of such information. 
 (c) The Receiving Party may disclose
Confidential Information of the Disclosing Party to its trustees, directors, officers, employees, consultants and advisors (including lawyers and accountants) on a need to know basis, in each case subject to appropriate confidentiality provisions
(or professional standards) reasonably acceptable to the Disclosing Party. 
 (d) Notwithstanding any other provision of this Letter
Agreement, nothing herein shall prohibit the Foundation from any of the following: (i) analyzing 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 any agreement with, any third party in furtherance of the Foundation’s charitable purpose, so long as in doing so, the Foundation does not disclose any Confidential Information except as
permitted pursuant to Sections 19(a) through (c). 
 20. Counterparts. 

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

 Appendix 6 

Gates Foundation Open Access Policy 
 The
Bill & Melinda Gates Foundation is committed to information sharing and transparency. We believe that published research resulting from our funding should be promptly and broadly disseminated. We have adopted an Open Access policy that
enables the unrestricted access and reuse of all peer-reviewed published research funded, in whole or in part, by the foundation, including any underlying data sets. 

As of January 1, 2015 our Open Access policy will be effective for all new agreements. During a two-year
transition period, publishers will be permitted to apply up to a 12-month embargo period on the accessibility of the publication and its underlying data sets. This embargo period will no longer be allowed
after January 1, 2017. 
 Our Open Access policy contains the following elements: 

 

	 	1.	 Publications Are Discoverable and Accessible Online. Publications will be deposited in a specified
repository(s) with proper tagging of metadata. 


  

	 	2.	 Publication Will Be On “Open Access” Terms. All publications shall be published under the Creative
Commons Attribution 4.0 Generic License (CC BY 4.0) or an equivalent license. This will permit all users of the publication to copy and redistribute the material in any medium or format and transform and build upon the material, including for any
purpose (including commercial) without further permission or fees being required. 


  

	 	3.	 Foundation Will Pay Necessary Fees. The foundation would pay reasonable fees required by a publisher to effect
publication on these terms. 


  

	 	4.	 Publications Will Be Accessible and Open Immediately. All publications shall be available immediately upon
their publication, without any embargo period.    An embargo period is the period during which the publisher will require a subscription or the payment of a fee to gain access to the publication. We are, however, providing a
transition period of up to two years from the effective date of the policy (or until January 1, 2017). During the transition period, the foundation will allow publications in journals that provide up to a
12-month embargo period. 


  

	 	5.	 Data Underlying Published Research Results Will Be Accessible and Open Immediately. The foundation will require
that data underlying the published research results be immediately accessible and open. This too is subject to the transition period and a 12-month embargo may be applied.
