 EXCLUSIVE START-UP LICENSE AGREEMENT 

This Exclusive License Agreement (this “Agreement”), effective as of the date of last signature (the “Effective
Date”), is made and entered into between the University of Washington, a public institution of higher education and an agency of the state of Washington, (“University”), and Neoleukin Therapeutics, Inc., a corporation
organized under the laws of the state of Delaware (“Company”). 
 BACKGROUND 

A.    Certain innovations relating to the de novo design of cytokine mimics (University reference number 48337; Stanford
University reference S18-238) were collaboratively made in (i) the University laboratory of Dr. David Baker (“Principal Investigator”), a University faculty member in the Department
of Biochemistry and an employee of the Howard Hughes Medical Institute (“HHMI”), and (ii) in the Stanford University laboratory of Dr. Chris Garcia, a Stanford University faculty member in the Department of Molecular and
Cellular Physiology (at Stanford University) and an employee of HHMI. In addition, certain innovations relating to [***] neoleukin-2/15 variants for [***] and targeted
IL-2 receptor binding (University reference number 48351) and de novo IL-2 antagonist (University reference number 48465) were made in the University laboratory of
Dr. David Baker. 
 B.    HHMI assigned its rights in such innovations (such rights via Dr. Baker) to
University and its rights in such innovations (such rights via Dr. Garcia) to Stanford University, each assignment subject to the HHMI License (as defined herein). University and Stanford University thus
co-own certain intellectual property rights in such innovations (University reference number 48337; Stanford University reference S18-238) , as listed in Exhibit A “Start-Up License Schedule” to this Agreement. University and Stanford University have executed an interinstitutional agreement (“IIA”), dated August 14, 2018, that authorizes
University to assume sole responsibility for both the patent prosecution and licensing of co-owned patent applications. University has shared a copy of the IIA with Company under the confidentiality terms of
the Option (as defined in Section 13.21). In addition, University solely owns certain intellectual property rights in innovations made in the course of University research relating to [***] neoleukin-2/15
variants for [***] and targeted IL-2 receptor binding (University reference number 48351) and de novo IL-2 antagonist (University reference number 48465), as listed in
Exhibit A “Start-Up License Schedule” to this Agreement. Thus, University has the right to license to others certain rights to use and practice such intellectual property. University is willing to
grant those rights so that such innovations may be developed for use in the public interest. 
 C.    Company desires
that University grant it an exclusive license under such intellectual property rights, and University is willing to grant such a license, on the terms set forth in this Agreement. 

AGREEMENT 
 The Parties
agree as follows:

(c) the merger of Company with a Third Party at arm’s length; provided, however, that in no event will any bona fide equity financing for the primary purpose of raising capital for corporate purposes be considered an Acquisition under this
Agreement.

the first Acquisition to occur after the Effective Date (but does not include any consideration received for any subsequent Acquisition). 

“Combination Product” means a product or service sold in a form containing a Licensed Product and at least one other product,
service, component, or ingredient which could be sold separate and apart from the Licensed Product and which is not required for the function of the Licensed Product (each, a “Combination Product”). For clarity, the combination of a
Licensed Product and the other product, service, component or ingredient may have an additive, synergistic or enhanced effect or response (i.e. above and beyond that of each individual component, but not required for function however) and that
additive, synergistic or enhanced effect or response will not be considered “required for the function” in the foregoing, such that the product or service will still be a Combination Product. 

“Confidential Information” means any information or materials of a Party not generally known to the public, including any
information comprised of those materials and Company’s business plans or reports. Confidential Information does not include any information that: (a) is, or becomes, part of the public domain through no fault of receiving Party;
(b) is known to receiving Party prior to the disclosure by the disclosing Party, as evidenced by documentation; (c) is publicly released as authorized under this Agreement by University, its employees or agents; (d) is subsequently
obtained by a Party from a Third Party who is authorized to have such information; or (e) is independently developed by a Party without reliance on any portion of the Confidential Information received from the disclosing Party and without any
breach of this Agreement as evidenced by documentation. 
 “Distributor” means a distributor, reseller or OEM to which
Company or any of its Sublicensees (each a “Licensed Party”) sells a Licensed Product for resale of Licensed Product by the Distributor, and where Distributor has no other rights with respect to the Licensed Rights other than to
resell or otherwise distribute Licensed Products (including but not limited to integrated or bundled with other products or services), and for which resale or distribution Company and Sublicensees receive no further consideration (including but not
limited to royalties and/or commissions) beyond the price for the initial sale of Licensed Product to the Distributor. 
 “Event of
Force Majeure” means an unforeseeable act that prevents or delays a Party from performing one or more of its duties under this Agreement and that is outside of the reasonable control of the affected Party. An Event of Force Majeure includes
acts of war or of nature, insurrection and riot, and labor strikes. An Event of Force Majeure does not include a Party’s inability to obtain a Third Party’s consent to any act or omission, unless the inability was caused by a separate
Event of Force Majeure. 
 “Fair Market Value” means the average price at which the stock in question is publicly trading
for twenty (20) days prior to the announcement of its purchase by the Sublicensee(s), or, if the stock is not publicly traded, the value of such stock as determined in good faith by the board of directors of Company or Sublicensee.

patent cooperation treaty (PCT), divisions, continuations, and claims in continuations-in-part that are entitled to claim priority to, or that share a common priority
claim with, and are directed to subject matter specifically described in any item listed on Exhibit A1.1 “Licensed Patents”; (c) any patents that issue from patent applications in clauses (a) and (b), (d) extensions,
renewals, substitutes, re-examinations and re-issues of any of the items in (a) or (b) or (c); and (e) foreign counterparts of any of the items in (a), (b), (c) or
(d) wherever and whenever filed. 
 “Licensed Product” means any method, process, composition, product, service, or
component part thereof that (a) would, but for the granting of the rights set forth in this Agreement, infringe a Valid Claim contained in the Licensed Patents and/or (b) uses or incorporates the Licensed
Know-How. 
 “Licensed Rights” means all rights granted to Company under Article 2
“License Grant” of this Agreement. 
 “Net Sales” means the gross invoiced amount (or otherwise received) by
Company or Sublicensee from Distributors, customers, end users and other Third Parties for sales, leases, and other dispositions of Licensed Products, less (a) all trade, quantity, and cash discounts and refunds actually allowed, including

determined in accordance with accepted accounting principles, standards and procedures (“GAAP”) or International Financial Reporting Standards (“IFRS”) consistently applied across all products sold by Company,
provided Company shall provide documentation upon University’s request that the allowance accurately represents the level of uncollectible or bad debt. On sales of Licensed Products by made in other than an arm’s length transaction, the
value of the Net Sales attributed to such transaction will be equal to the Net Sales that which would have been received in an arm’s length transaction, based on sales of like quantity and quality of Licensed Products sold on or about the time
of the transaction. Net Sales does not include sale, lease, disposition or other transfer of Licensed Products among or between Company, Subsidiaries and Sublicensees for the purpose of subsequent resale to a Third Party, but does include subsequent
resale to such Third Party. For avoidance of doubt Net Sales are calculated on sales by Company or Sublicensee to Distributor, and not on the subsequent sale by Distributor.

purpose of determining running royalties of the Combination Product shall be calculated by multiplying actual Net Sales of the Combination Product by the fraction A/C where “A” is the Net Sales price of the Licensed Product, if sold
separately, and “C” is the Net Sales price of the Combination Product. If, on a country-by-country basis, neither the Licensed Product, nor the other product,
component or ingredient or service in the Combination Product, is sold separately in said country, Net Sales for the purpose of determining running royalties of the Combination Product shall be determined in good faith by the Parties. A Combination

“Sublicense Consideration” means all consideration, but excluding royalties on Net Sales, received by Company from each
Sublicensee for the grant of a Sublicense. For avoidance of doubt, consideration paid to Company by Sublicensees for the following shall not be deemed Sublicense Consideration: (a) documented bona fide performance of Licensed Product
development work, research work, clinical studies and regulatory approvals performed (including such work, studies, and approvals done in a collaboration) by Company and for clarity such development work, research work, clinical studies and

2.2.    Know-How License. University hereby grants to
Company a non-exclusive, worldwide license to use Licensed Know-How. Unless otherwise terminated under Article 9 “Termination”, the term of this license will
begin on the Effective Date and will continue until all rights under Licensed Patents are terminated. Upon the expiration of this Agreement pursuant to Section 9.1 “End of Term”, but not early termination, University shall not assert
(or purport to assert or grant rights to any Third Party to assert) the Licensed Know-How against Company or its successors or Sublicensees. 

2.3.    Sublicense Rights. Company has the right, exercisable during the term of this
Agreement, to Sublicense its exclusively Licensed Rights under this Agreement; Company may also during the term of this Agreement sublicense its rights in non-exclusively Licensed Rights, but only for the
purpose of using in conjunction with exclusively Licensed Rights. Company may not grant Sublicensees the right to enforce Licensed Rights directly. Company will remain responsible for its obligations under this Agreement. Except for Permitted
Sublicensees, Company will ensure that the Sublicense agreement: (a) contains terms and conditions that require Sublicensee to comply with the terms and conditions of this Agreement applicable to Sublicensees, including a release substantially
similar to that provided by Company in Section 10.1 “Company’s Release”; a warranty substantially similar to that provided by Company in Section 11.1 “Authority”; University disclaimers and exclusions of warranties

executed Sublicense, excluding any Permitted Sublicense agreement, within thirty (30) days after its execution. Company will not enter into any Sublicense agreement if the terms of such agreement are inconsistent in any material respect with
the material terms of this Agreement. Any Sublicense made in violation of this Section 2.3 “Sublicense Rights” will be void and will constitute an event of default that requires remedy under Section 9.2 “Termination by
University”. 
 2.4.    Limitation of Rights. No provision of this Agreement grants to
Company, by implication, estoppel or otherwise, any rights other than the rights expressly granted it in this Agreement under the Licensed Rights, including any license rights under any other University-owned or Stanford University-owned technology,

 2.5    The United States
Government’s Rights. Inventions covered in the Licensed Patents arose, in whole or in part, from federally supported research and the federal government of the United States of America has certain rights
in and to such inventions as those rights are described in Chapter 18, Title 35 of the United States Code and accompanying regulations, including Part 401, Chapter 37 of the Code of Federal Regulation. The Parties’ rights and obligations under
this Agreement to any government-funded inventions, including the grant of license set forth in Section 2.1 “Patent License”, are subject to the applicable terms of the aforementioned United States laws. The U.S. Government is
entitled, as a right, under these Chapters: (a) to a nonexclusive, nontransferable, irrevocable, paid-up license to practice or have practiced for or on the behalf of the U.S. Government any of the
federally funded inventions throughout the world and (b) to exercise march in rights on the federally funded inventions. Company further agrees that, to the extent required by Title 35 Section 204 of the United States Code, it will
substantially manufacture in the United States of America all products embodying or produced through the use of any such federally funded invention. 

2.6    Rights to Wholly Owned Subsidiaries of Company. Company may extend rights granted to Company
under this Agreement to wholly owned subsidiaries (“Subsidiaries”) of Company, provided that (a) Company is responsible for all acts of such Subsidiaries as if they were acts of the Company, (b) such Subsidiary is bound to
perform all obligations to University and HHMI of this Agreement other than making payments pursuant to Article 6 “Payments, Reimbursements, Reports, and Records”, as if such Subsidiary were Company, and (c) Company reports to
University pursuant to Section 13.10 “Notices” that such Subsidiary will be exercising rights under this Agreement prior to such Subsidiary exercising any such rights under this Agreement. For avoidance of doubt, Company may perform
any obligation of Subsidiary on Subsidiary’s behalf. 
 2.7    HHMI Research Use Rights.
Company acknowledges that it has been informed that the Licensed Patents and Licensed Know-How were were developed, at least in part, by employees of HHMI and that HHMI has a fully paid-up, non-exclusive, irrevocable, worldwide license to exercise any intellectual property rights with respect to the Licensed Patents and Licensed Know-How for research purposes, ,with the right to sublicense to non-profit and governmental entities, but with no other right to assign or sublicense (the “HHMI
License”). This license is explicitly made subject to the HHMI License. 
 2.8    IIA.
University represents and warrants that, to the best of UW CoMotion’s knowledge, under the IIA it has obtained all necessary rights from Stanford with respect to the Licensed Patents sufficient to grant the licenses and rights granted under
this Agreement. During the term of this Agreement, University shall not (i) amend or modify the IIA which would restrict or narrow the scope of Company’s rights granted hereunder, or which would impose additional obligations upon Company
hereunder, (ii) waive any of University’s rights under the IIA which would restrict or narrow the scope of Company’s rights granted hereunder, or which would impose additional obligations upon Company hereunder, or

 3.    RIGHTS OF UNIVERSITY; LIMITATIONS 

3.1    University’s Rights. University reserves all rights not expressly granted
to Company under this Agreement. University retains for itself, Stanford University, and other not-for-profit academic research institutions, an irrevocable,
nonexclusive license to practice Licensed Rights for academic research, instructional, or any other academic or non-commercial purpose. University retains for itself an irrevocable, nonexclusive license to
practice Licensed Rights for clinical purposes. Expressly included within University’s reservation of rights is to do the following in connection with academic research, instructional, or any other academic or
non-commercial purposes: (a) to use the Licensed Rights in sponsored research or collaborative research with any Third Party, but not for any commercial purpose, and only to the extent that no such Third
Party is granted any commercialization rights of any kind under the Licensed Rights or to commercialize Licensed Products, (b) to grant material transfer agreements to the extent that the use of such materials is restricted to academic
research, teaching and or other scholarly activities, and (c) to publish any information included in the Licensed Rights or any other information that may result from University’s or Stanford University’s research. For the avoidance
of doubt, nothing in this Section 3.1 or elsewhere in this Agreement is intended to or shall be construed to alter, restrict, or limit the HHMI License. 

3.2    Sublicensing Opportunities. If a Third Party notifies University that it wishes to license
any of the exclusively licensed Licensed Rights in any field or territory in which Company is unable or unwilling to develop and market a Licensed Product, University will notify Company of such Third Party’s wish to obtain such license, and
Company will have good faith discussions with such Third Party regarding the terms and conditions under which such Sublicense could be obtained. Company will not be obligated to provide such sublicense where it interferes with Company’s (or its
Sublicensee’s) business strategy; however, Company will not unreasonably withhold such Sublicense. 

3.3    Reservation of Rights for Humanitarian Purposes. Consistent with 35 U.S.C. §200 et
seq., University retains the right to require Company to grant Sublicenses to responsible applicants in the Field of Use under the Licensed Patents on terms that are reasonable under the circumstances; or, if Company fails to grant a license, to
grant the license itself. The exercise of these rights by University will only be in exceptional circumstances and only if University determines (a) the action is necessary to meet health or safety needs that are not reasonably satisfied by
Company; or (b) the action is necessary to meet requirements for public use specified by federal regulations, and such requirements are not reasonably satisfied by Company, and (c) the action will not have a significant negative effect on
Company’s (or its Sublicensee’s) business strategy with respect to the Licensed Products. University will not require the granting of a sublicense, and will not grant the license itself, unless the responsible applicant has first
negotiated in good faith with Company. Company shall be entitled to use the dispute resolution mechanisms of Section 13.4 “Escalation; Dispute Resolution”, including seeking an injunction from the court if mediation is unsuccessful,
if Company wishes to dispute that University should be entitled to exercise its rights under this Section 3.3. 
 4.
    APPLICATIONS AND PATENTS 

4.1    Pre-Agreement Patent Filings. Company has reviewed
the Licensed Patents and as of the Effective Date is not aware of any basis to challenge or dispute the inventorship, validity, or enforceability of any of the claims made in the Licensed Patents.

 4.2    Patent Prosecution Decisions. University
and Company will consult on the preparation, filing and prosecution of the Licensed Patents (including, without limitation, on the selection of patent counsel). Patent counsel will be directed to deliver to Company all written and electronic
communications to and from all patent offices and foreign counsel, and provide summaries of oral communications with patent offices. Provided Company is in compliance with Section A3.8 “Patent Expense Payment” of Exhibit A “Start-Up License Schedule”, Company’s directions regarding patent preparation, filing and prosecution will be followed unless detrimental to University’s intellectual property rights. University
and Company will consult prior to deciding in which countries to pursue patent protection and provided Company is in compliance with Section A3.8 “Patent Expense Payment”, patents will be filed in all countries Company designates.
University acknowledges the key role and value of the Licensed Patent portfolio to Company and the need for timely review and exchange of information between University and Company prior to Licensed Patent portfolio decisions. University will remain
the client of record, and may at its own expense instruct patent counsel to take actions necessary to protect University’s intellectual property rights, if in University’s reasonable opinion, Company actions will result in a loss of
rights; provided that for any such actions, if Company declines to reimburse University pursuant to Section A1.1 “Licensed Patents”, those applications and resultant patents will not be subject to this Agreement. In no event will Company
file a patent application where all of the inventors are under University policy obligated to assign their rights in such patent application to University. 

4.3    Assumption of Patent Prosecution and Maintenance. Provided Company is in compliance with
Section A3.8 “Patent Expense Payment” of Exhibit A “Start-Up License Schedule”, University will take all commercially reasonable steps to cause patents and patent applications within the
Licensed Patents to be diligently prosecuted and maintained. If Company is in compliance, and University, against Company’s instructions, decides to abandon or allow to lapse any patent application or any claim of any patent included in the
Licensed Patents or not pursue patent protection for any foreign patent mutually agreed upon by the Parties under Section 4.2 “Patent Prosecution Decisions”, University will notify Company at least sixty (60) days before such
decision would be effective, and Company will have the right to file, prosecute, and maintain, as applicable, such patent or patent application in University’s name at Company’s expense provided Company shall keep University informed of
such activity. Company may thereafter abandon or allow to lapse any or all patents or patent applications for which it is responsible. Company will notify University of any abandoned or lapsed patents at least thirty (30) days prior to such
abandonment or lapse.

 5.2    Renegotiation of Performance Milestones. If
Company determines that it will be unable to achieve a Performance Milestone, Company will so notify University in advance of the Performance Milestone Date, Company may request a Performance Milestone Extension (as described below) or, providing
Company demonstrates it is diligently pursuing development and commercialization of at least one Licensed Product, Company may request that the Parties negotiate an appropriate new Performance Milestone and/or related Performance Milestone Date in
good faith. If the Parties are unable to agree on a renegotiated Performance Milestone within sixty (60) days after commencing negotiations, University may proceed with its termination rights under Section 9.2 “Termination by
University”, subject to both Company and University having the right to seek mediation under Section 13.4 “Escalation; Dispute Resolution”. In addition, if for any reason Company will be unable to achieve a Performance Milestone,
then upon written notice to University and payment of [***] US dollars ($[***]), the timing for the Performance Milestone will be extended for one (1) year (“Performance Milestone Extension”) (and the timing for each subsequent
Performance Milestone will likewise be extended for one (1) year. Company shall have the right to three (3) Performance Milestone Extensions by providing such notice and paying such fee. In the case that Company is unable to achieve a
Performance Milestone (after any extensions provided for above) and University proceeds with its termination rights under Section 9.2 “Termination by University”, University will only have the right to terminate the particular
performance category (e.g. agonist protein biologic, [***] molecular entity, or antagonist protein biologic) for such failed Performance Milestone, with such termination effectively removing such performance category from the Field of Use, and the
Agreement would continue with respect to the other performance categories. 

5.3    Commercialization Reports. Throughout the term of this Agreement and during the Sell-Off Period, and within [***] of December 31st of each year, Company will deliver to University written reports of Company’s and Sublicensees’
efforts and plans to develop and commercialize the innovations covered by the Licensed Rights and to make and sell Licensed Products. Company will have no obligation to prepare commercialization reports in years where (a) Company delivers to
University a written Sales Report with active sales, and (b) Company has fulfilled all Performance Milestones. In relation to each of the Performance Milestones each commercialization report will include sufficient information to demonstrate
compliance of those Performance Milestones and will set out timeframes and plans for those Performance Milestones which have not yet been met. 

5.4    Company Information. Once per year, until University no longer has Shares in Company,
Company shall provide a current capitalization chart to indicate the number of Shares University owns in Company, and total number of Shares and Fully Diluted Shares. Throughout the term of this Agreement, Company shall provide the names of, and
sufficient contact information to identify, any Permitted Sublicensees within [***] of University’s written request. Upon University’s inquiry, Company will provide information on funding rounds to date (type, date, and amount) and number

 6.2    Currency and Checks. All computations and
payments made under this Agreement will be in United States dollars. The exchange rate for the currency into dollars as reported in The Wall Street Journal as the New York foreign exchange

non-United States dollar currencies. 
 6.3    Late
Payments. University may charge Company a late fee for all amounts owed to University that are more than thirty (30) days overdue. The late fee will be computed as the United States prime rate plus two percent (2%), compounded monthly, as

as a consequence of the lateness of any payment. 
 6.4    Sales Reports. Within [***] after the
last day of each calendar quarter commencing the calendar quarter after the Company effects its first commercial sale of a Licensed Product and during the term of this Agreement and the Sell-Off Period,

if Company is not required hereunder to pay to University a royalty payment during the calendar quarter. Company shall provide the names of Permitted Sublicensees within [***] at University’s request. 

6.5    Books and Records. Throughout the term of this Agreement and for [***] thereafter,
Company, at its expense, will keep and maintain and shall cause each Sublicensee other than Permitted Sublicensees to keep and maintain complete and accurate records of all sales, leases, and other dispositions of Licensed Products and all
other records related to this Agreement. 
 6.5.1    Audit Rights. Company will permit at the
request of University (not to be made more than once in any given calendar year), one or more independent, certified accountants selected by University and reasonably acceptable to Company (which acceptance shall not be unreasonably withheld or
delayed) (“Accountants”) to have access to Company’s records and books of account pertaining to calculation of Net Sales and payment of any other amounts owed under this Agreement. Accountants’ access will be during
ordinary working hours to audit Company’s records for any payment period ending prior to such request, the correctness of any Sales Report or payment made under this Agreement, or to obtain information as to the payments due for any period in
the case of failure of Company to report or make payment under the terms of this Agreement or to verify Company’s compliance with its payment obligations hereunder. Accountants will sign Company’s standard
non-disclosure agreement provided it is reasonable to the industry in which Company operates. Company shall cause each Sublicensee, other than Permitted Sublicensees, that manufactures, sells, leases, or
otherwise disposes of Licensed Products on behalf of Company to grant University the right to inspect and audit Sublicensee’s records.

7.2    Company’s Right to Enforce. During the term of this Agreement, Company

provided that (a) Company must notify University at least ten (10) days before Company wishes to file suit, and (b) Company will reimburse University for all reasonable legal fees and costs incurred by University in connection with
such action. As examples of why University may reasonably deny the request to be joined as a party plaintiff: (i) Company is no longer developing or commercializing a Licensed Product, or (ii) there is not credible evidence of actual

which consent shall not be unreasonably withheld or delayed.

out-of-pocket expenses directly related to any action, suit, or settlement for infringement of the Licensed Rights. Any payment by an alleged infringer that, under the
terms of the applicable settlement agreement or judgment, (a) constitutes consideration for Net Sales of infringing product (or an equivalent characterization in the nature of a product royalty) will be handled according to the payment
provisions in Section A3.2 “Running Royalty Payments”, and (b) constitutes consideration for the grant of a Sublicense (or an equivalent characterization) will be handled according to Section A3.6 “Sublicense Consideration”.
Any remaining proceeds will be distributed [***] percent ([***]%) to Company and [***] percent ([***]%) to University.

 7.4    Limitation on Infringement Actions.
Excluded from the rights granted herein is the right to bring an infringement action against a not-for-profit entity for infringement of the Licensed Rights in carrying
out not-for-profit research. 

7.5    University Right to Institute Action. If Company fails, within [***] of receiving of the
University’s written request to take action against an alleged infringer of exclusively Licensed Rights, to secure cessation of the infringement, institute suit against the infringer, or to provide to University satisfactory evidence that
Company is engaged in bona fide negotiations for the acceptance by infringer of a Sublicense to the relevant Licensed Rights, then University may, upon written notice to Company, assume full right and responsibility to secure cessation of the
infringement or institute suit against the infringer, or secure acceptance of a Sublicensee by Company from the alleged infringer in the relevant Licensed Patents provided that the scope of the Sublicense would only be the extent of the infringement
at the time of University’s request for Company to take action against the infringer, and further provided that Company will not be liable for any actions or inactions of the Sublicensee. If University, in accordance with the terms and
conditions of this Agreement, chooses to institute suit against an alleged infringer, University may bring such suit in its own name (or, if required by law, in its and Company’s name) and at its own expense, and Company will, but at
University’s expense for Company’s direct associated expenses, fully and promptly cooperate and assist University in connection with any such suit. All license fees, royalties, damages, awards, or settlement proceeds arising from such a
University-initiated action will be solely for the account of University.

8.2    Third Party Actions. In the event of a Third Party legal action challenging the validity or
enforceability of any of the exclusively Licensed Rights, Company in its sole discretion will have the right to assume and control the sole defense of the claim at Company’s expense. Company will not settle any suits or actions in any manner
relating to the Licensed Rights without obtaining the prior written consent of University, which consent shall not be unreasonably withheld or delayed; provided, however, that the Parties agree that loss of University’s intellectual property
rights is a reasonable reason to withhold consent. Further, if Company is not diligently protecting University’s intellectual property rights, or if Company does not elect to assume and control the sole defense of the Third Party legal action
within ninety (90) days after becoming aware of challenge, University will have the right to assume the defense of the action at its own expense. University will not settle any suits or actions in any manner relating to the Licensed Rights
without considering in good faith any comments from Company.

9.3    Events of Default. University may terminate this Agreement by delivering to Company a
written notice of termination at least [***] days prior to the date of termination if Company (i) permanently ceases operations; (ii) voluntarily files or has filed against it a petition under applicable bankruptcy or insolvency laws that

general assignment for the benefit of creditors; or (v) if Company challenges the validity of the Licensed Patents. 

9.4    Disputing Events of Default. Notwithstanding the foregoing, if Company disputes that a

of this Agreement, subject to being in compliance with Article 6 “Payments, Reimbursements, Reports, and Records” of this Agreement at the time of termination, and subject to ongoing compliance with obligations under Article 6
“Payments, Reimbursements, Reports, and Records”, Company and any Sublicensees and Distributors may sell or otherwise dispose of existing inventory of Licensed Products for a period of [***] after the effective date of termination of this

to University within [***] of either the effective date of termination or the end of the Sell-Off Period if University has been notified pursuant to the preceding sentence.

 9.7    Final Report to University. Within [***]
after the end of the calendar quarter following either the expiration or termination of either this Agreement or the Sell-Off Period, whichever is later, Company will submit a final Sales Report to University.
Any payment obligations accrued prior to such termination or expiration, including those incurred but not yet paid, will become due and payable at the same time as this final Sales Report is due to University. 

9.8    Sublicenses After Termination. At any time within [***] following termination of this
Agreement, a Sublicensee may notify University that it wishes to enter into a direct license with University in order to retain its rights to the Licensed Rights granted to it under its Sublicense (such [***] following termination, the
“Initial Notice Period”). Following receipt of such notice, University and Sublicensee will enter into a license agreement the terms of which will be substantially similar to the terms of this Agreement. The scope of the direct
license, the licensed territory, and the duration of the license grant will be comparable to the corresponding terms granted by Company to such Sublicensee, provided that such Sublicensee will be granted at least the same scope of rights as it
obtained from Company under its Sublicense. For the sake of clarity, the financial terms, including without limitation, the running royalty rate and milestone payments, will be identical to the corresponding financial terms set forth in this
Agreement, provided University shall consider in good faith reducing the non-running royalty financial payments where there are multiple direct licensees or such direct licensee has a reduced scope compared
with this Agreement. Notwithstanding the foregoing, each Sublicensee’s right to enter into such direct license will be conditioned upon: 

9.8.1    Written Notification to University. Such Sublicensee informing University in writing,
pursuant to Section 13.10 “Notices”, that it wishes to enter into such direct license with University, within the Initial Notice Period; 

9.8.2    Sublicensee in Good Standing. Such Sublicensee being in good standing with Company

Sublicensee pursuant to the terms of Section 2.3 “Sublicense Rights”; 

9.8.4    Sublicensee Certification that Conditions are Satisfied. Such Sublicensee using reasonable
efforts to certify or otherwise demonstrate that the conditions set forth in Subsections 9.8.1 “Written Notification to University”, 9.8.2 “Sublicensee Good Standing”, and 9.8.3 “Valid Sublicense” have been met within
thirty (30) days of expiration of the Initial Notice Period (or within such longer period of time as University agrees is reasonable under the circumstances, based on the nature and extent of any documentation reasonably requested by
University); and

 9.8.5    Time Limitations. Unless mutually agreed
by the Parties in writing, such negotiations for a direct license are not to exceed [***] from the end of the Initial Notice Period. 

Except as set forth in Subsection 9.8.5 “Time Limitations”, University may, at its sole discretion, waive any of these requirements.
If all of the conditions set forth in this Section 9.8 are met, then Sublicensee will be granted such direct license by University. If any condition set forth in this Section 9.8 is not met, then after expiration of any time period granted
to Sublicensee with respect to meeting such condition (for example and to the extent applicable, the Initial Notice Period and/or the periods described in Subsections 9.8.4 “Sublicensee Certification that Conditions are Satisfied” and
9.8.5 “Time Limitations”), Sublicensee will not practice Licensed Rights except as provided for in Section 9.6 “Effect of Termination” and University will be free to license or not license Licensed Rights to such Sublicensee
according to University’s sole discretion. 
 10.    RELEASE, INDEMNIFICATION, AND INSURANCE

 10.1.    Company’s Release. Company hereby releases University, Stanford
University and their regents, employees, and agents forever from any and all suits, actions, claims, liabilities, demands, damages, losses, or expenses (including reasonable attorneys’ and investigative expenses) relating to or arising out of
(a) the manufacture, use, lease, sale, or other disposition of a Licensed Product by Company, Sublicensee(s), Distributor(s), or any other party authorized by Company to practice the License Rights; or (b) the assigning or sublicensing of
Company’s rights under this Agreement. 
 10.2.    Indemnification. Company will indemnify,
defend, and hold harmless University, Stanford University, and their regents, employees, and agents (each, an “Indemnitee”) from all Third Party suits, actions, claims, liabilities, demands, damages, losses, or expenses (including
reasonable attorneys’ and investigative expenses), arising out of Company’s or Sublicensees’ exercise of any rights with respect to Licensed Products, including, without limitation, personal injury, property damage, breach of contract
and warranty and products-liability claims relating to a Licensed Product and claims brought by a Sublicensee (each, a “Claim”), provided that the Company will not have obligations to the extent resulting from the University’s
or Stanford University’s gross negligence or willful misconduct. In the event of a Claim, the Indemnitee against whom a Claim is brought will: (a) give Company written notice of the Claim within a reasonable period of time after such
Indemnitee receives notice thereof along with sufficient information for Company to identify the Claim; and (b) cooperate and provide such assistance (including, without limitation, testimony and access to documentation within the possession or
control of such Indemnitee) as Company may reasonably request in connection with Company’s defense, settlement and satisfaction of the Claim. Company will pay or reimburse all costs and expenses reasonably incurred by such Indemnitee to
provide any such cooperation and assistance. Any settlement that would admit liability on the part of University or Stanford University or that would involve any relief other than the payment of monetary damages will be subject to the approval of
University and/or Stanford University, such approval not to be unreasonably withheld. HHMI, and its trustees, officers, employees, and agents (collectively, “HHMI Indemnitees”), will be indemnified, defended by counsel acceptable to
HHMI, and held harmless by Company from and against any claim, liability, cost, expense, damage, deficiency, loss, or obligation, of any kind or nature (including, without limitation, reasonable attorneys’ fees and other costs and expenses of
defense) (collectively, “HHMI Claims”), based upon, arising out of, or otherwise relating to this Agreement or any Sublicense or Permitted Sublicense, including without limitation any cause of action relating to product liability.
The previous sentence will not apply to any HHMI Claim that is determined with finality by a court of competent jurisdiction to result solely from the gross negligence or willful misconduct of an HHMI Indemnitee. Notwithstanding any other provision
of this Agreement, Company and Sublicensee’s obligations to defend, indemnify and hold harmless the HHMI Indemnitees under this paragraph will not be subject to any limitation or exclusion of liability or damages or otherwise limited in any
way.

13.1.    Amendment and Waiver. This Agreement may be amended from time to time only by a written
instrument signed by the Parties. No term or provision of this Agreement will be waived, and no breach excused, unless such waiver or consent is in writing and signed by the Party claimed to have waived or consented. No waiver of a breach will be
deemed to be a waiver of a different or subsequent breach. 
 13.2.    Assignment. The rights and
licenses granted by University in this Agreement are personal to Company and Company will not assign its interest or delegate its duties under this Agreement without the written consent of University, which consent will not to be unreasonably
withheld or delayed; any such assignment or delegation made without written consent of University will not release Company from its obligations under this Agreement. Notwithstanding the foregoing, Company, without the prior approval of University,
may assign all, but no less than all, of its rights and delegate all, but no less than all, of its duties under this Agreement to a Third Party provided that: (a) the assignment is made to such Third Party as a part of and in connection with an
Acquisition, (b) Company obtains from such Third Party written agreement to honor all obligations under this Agreement accrued by Company before Acquisition and all obligations under this Agreement to accrue by such Third Party assignee after
Acquisition, and (c) Company provides written notice to University of the Acquisition, together with a substitution of parties document or copy of the assignment confirming compliance with (b) above, no later than thirty (30) days
after the close of the Acquisition. Any assignment made in violation of this Section 13.2 “Assignment” is void and will constitute an act of breach that requires remedy under Section 9.2 “Termination by University”.
This Agreement will inure to the benefit of Company and University and their respective permitted assignees and trustees. 

13.3.    Confidentiality. 

13.3.1    Form of Transfer. Confidential Information may be conveyed in tangible or intangible
form. Disclosing Party must clearly mark its Confidential Information “confidential.” If disclosing Party communicates Confidential Information in non-written form, it will reduce such communications
to writing, clearly mark it “confidential,” and provide a copy to receiving Party within thirty (30) days of original communication at the address in Section 13.10 “Notices”. Any business information delivered by
Company as required under this Agreement shall be deemed marked “confidential,” whether or not such confidential marking appears. 

13.3.2    No Unauthorized Disclosure of Confidential Information. Beginning on the Effective Date
and continuing throughout the term of this Agreement and thereafter for a period of five (5) years, receiving Party will not disclose or otherwise make known or available to any Third Party any disclosing Party Confidential Information, without
the express prior written consent of disclosing Party. Notwithstanding the foregoing, receiving Party will be permitted to disclose Confidential Information of disclosing Party to (i) actual or potential investors, lenders, consultants,
advisors, collaborators, Sublicensees, or development partners, which disclosure will be made under conditions of confidentiality and limited use and (ii) its attorney or agent as reasonably required and (iii) to employees and trustees of
HHMI who have a need to know. In no event will receiving Party incorporate or otherwise use disclosing Party’s Confidential Information in connection with any patent application filed by or on behalf of receiving Party. Receiving Party will
restrict the use of disclosing Party’s Confidential Information to uses exclusively in accordance with the terms of this Agreement. Receiving Party will use reasonable procedures to safeguard disclosing Party’s Confidential Information. In
the case where Company is the receiving Party, Company’s confidentiality obligations will also apply equally to Sublicensees.

 13.3.3    Access to University Information.
University is an agency of the state of Washington and is subject to the Washington Public Records Act, RCW 42.56 et seq., (“Act”), and no obligation assumed by University under this Agreement will be deemed to be inconsistent with
University’s obligations as defined under the Act and as interpreted by University in its sole discretion. If University receives a request for public records under the Act for documents containing Company Confidential Information, and if
University concludes that the documents are not otherwise exempt from public disclosure, University will provide Company notice of the request before releasing such documents. Such notice will be provided in a timely manner to afford Company
sufficient time to review such documents and/or seek a protective order, at Company’s expense utilizing the procedures described in RCW 42.56.540. University will have no other obligation to protect Company Confidential Information from
disclosure in response to a request for public records. 
 13.3.4    Disclosure as Required by
Law. Either Party will have the right to disclose the other Party’s Confidential Information as required by law or valid court order, provided that such Party will inform the Party who owns such Confidential Information prior to such
disclosure, will cooperate with the owner Party’s efforts to limit or avoid disclosure, and will limit the scope and recipient of disclosure to that required by such law or court order. 

13.4.    Escalation; Dispute Resolution. If (a) Company disputes that (i) a default has
occurred as contemplated in Section 9.2 “Termination by University”, or that a default has not been cured, or (ii) Company wishes to dispute termination of this Agreement resulting from a failed negotiation of a new Performance
Milestone as contemplated under Section 5.2 “Renegotiation of Performance Milestones”, then Company may provide University with a written dispute notice (“Dispute Notice”) prior to expiration of the [***]-day cure
period referenced in Section 9.2, stating the basis of Company’s disagreement with respect to such default or cure, or (b) if there is a dispute as provided under Sections 3.3 or 7.2, then either Party may provide the other with a
Dispute Notice. If Company disputes that a default has occurred as contemplated in Section 9.3 “Events of Default”, then Company may provide University with a Dispute Notice within [***] days of University sending the notice of
termination referenced in Section 9.3. Upon receipt of a Dispute Notice, University’s right to terminate this Agreement will be suspended and all rights under this Agreement will continue unaffected provided the dispute resolution process
in this Section 13.4 “Escalation; Dispute Resolution” is being exercised. Any dispute will first be escalated to Company’s Chief Executive Officer or to a representative from Company’s Board of Directors, and to
University’s Vice President for Innovation Strategy, representatives of which will be instructed to work in good faith to attempt to reach a mutually acceptable resolution of the dispute that would avoid termination of this Agreement. If the
representatives are unable to reach such resolution of the dispute within [***] days of delivery of the Dispute Notice, an independent, neutral mediator acceptable to both Parties (acting reasonably) will be appointed. The Parties will submit their
dispute to mediation according to such parameters as they may mutually agree in writing. The Parties agree to discuss their differences in good faith and to attempt in good faith, with facilitation by the mediator, to reach an amicable resolution of
the dispute within [***] days after the mediator’s appointment. If the Parties are not able to agree on resolution of the dispute within such period, or within [***] days of the Dispute Notice, whichever is earlier, including
agreeing on a new Performance Milestone pursuant to Section 5.2 “Renegotiation of Performance Milestones” if that is the subject of the dispute, then the dispute resolution process of this Section 13.4 “Escalation; Dispute
Resolution” will be complete and either Party may pursue any other action that is legally available to it. Notwithstanding the foregoing, no dispute affecting the rights or property of HHMI shall be subject to arbitration.

 13.15    Relationship with Principal
Investigator(s). Company acknowledges that Principal Investigator(s) is employed by HHMI and has certain pre-existing obligations to HHMI and University, including obligations with respect to disclosure
and ownership of intellectual property and obligations arising from sponsored research agreements between University and Third Parties. Accordingly, Company agrees that to the extent that any consulting agreement between Company and Principal
Investigator(s) is inconsistent with any of Principal Investigator(s)’s obligations to HHMI or University, including the reporting of all inventions developed while employed by HHMI (regardless of where arising) and including contractual
obligations arising under any sponsored research agreements between University and Third Parties, then Principal Investigator(s)’s obligations to HHMI and University will prevail and to such extent any inconsistent provisions of such consulting
agreement will be deemed inapplicable and unenforceable.

event will Company grant, or permit any person to assert or perfect, a security interest in the Licensed Rights; however, Company may grant or permit a security interest in the Company’s rights under this Agreement.

and Records” will survive termination of this Agreement with respect to obligations that accrued prior to thermination, including Net Sales during the Sell-Off Period as authorized under Seciton 9.6, and
further provided that Reports will not be required for any period in which there are no Net Sales other than the final report due under Section 9.7 “Final Report to University”. The obligation specified in Section 2.2 “Know-How License” will survive the expiration of this Agreement. The obligations and rights set forth in Section 2.7 “HHMI Research Use Rights”; Articles 9 “Termination”, 10
“Release, Indemnification, and Insurance”, 11 “Warranties”, 12 “Damages”; Sections 13.3 “Confidentiality”, 13.17 “Survival”, 13.19 “Applicable Law”, Section 13.20 “Forum

obligation or otherwise breaches one or more of the terms of this Agreement, the other Party may recover from the non-performing breaching Party all its costs (including actual attorneys’ and
investigative fees) to enforce the terms of this Agreement. 
 13.19    Applicable Law. The
internal laws of the state of Washington will govern the validity, construction, and enforceability of this Agreement, without giving effect to the conflict of laws principles thereof. 

13.20    Forum Selection. Any suit, claim, or other action to enforce the terms of this Agreement
will be brought exclusively in the state and federal courts of King County, Washington. Company hereby submits to the jurisdiction of that court and waives any objections it may have to that court asserting jurisdiction over Company or its assets
and property. 
 13.21    Entire Agreement. Company has evaluated the innovations and Licensed
Patents under a Confidentiality Agreement (“CDA”) with University (UW reference number 43597A), dated September 14, 2018. In addition, Company and University executed an exclusive option agreement (“Option”)
for certain Licensed Patents, with University reference UW reference number 43729A, dated November 29, 2018. This Agreement (including all attachments, exhibits, and amendments) is the final and complete understanding between the Parties

nondisclosure for Confidential Information disclosed under the CDA and Option will survive according to the terms of those agreements. Confidential Information disclosed under this Agreement will be governed by the terms of this Agreement.
This Agreement may not be modified in any manner, except by written agreement signed by an authorized representative of both Parties.

January 31st following the third anniversary of the Effective Date, and [***] ($[***]) due on January 31st following the fourth anniversary of
the Effective Date and all subsequent January 31st thereafter; provided that no annual maintenance fee will be due in any year Company pays minimum annual royalties. 

A3.2    Running Royalty Payments. Company will pay to University within [***] days after the last
day of each calendar quarter during the term of this Agreement an amount equal to [***]% of Net Sales during such quarter as a running royalty payment. On a
country-by-country basis, and a Licensed Product-by-Licensed Product basis, if in a
country there is no Valid Claim that covers the Licensed Product, then the foregoing royalty rate shall be reduced by [***] percent ([***]%) with respect to Net Sales of such Licensed Product in such country. 

A3.2.1    Third Party Royalties. If Company or its Sublicensees are required to pay
royalties to a Third Party based on Company’s or such Sublicensee’s manufacture, use, offer for sale, sale or import of Licensed Product subject to one or more patents of such Third Party that create a total royalty burden for the Licensed
Product of greater than [***] percent ([***]%) (such figure including the above running royalty to University), then the royalty Company pays to University may be reduced by the lesser of (i) [***] percent ([***]%) of the royalty otherwise due to
the University absent of a Third Party royalty reduction, (ii) [***] percent ([***]%) of the royalty actually paid to the Third Party, or (iii) the percent Company may reduce such Third Party royalty by based on a royalty stacking provision for
the same product. To qualify for this reduction the Third Party patent must be required for the manufacture, use, offer for sale, sale or import of the Licensed Product 

A3.3    Minimum Annual Royalties. Company will pay minimum annual royalties for the term of this
Agreement, to be creditable against running royalty payments for the preceding calendar year on a non-cumulative basis and to be due in full and payable on January 31st of each year beginning on January 31st

Stock Subscription Agreement attached hereto as Exhibit C; provided, however, that solely for purposes of this initial issuance of Shares, Company’s Fully-Diluted Shares shall exclude all then-outstanding convertible promissory notes
issued by the Company. In addition, Company agrees to issue additional Shares to University sufficient to cause the University to own in aggregate [***] percent ([***]%) of Company’s Fully-Diluted Shares through such time as the Company has
raised Qualified Financing; provided, however, that if Company closes an equity financing that would result in its cumulative equity capital raised being in excess of the Qualified Offering Proceeds, any such excess capital (and resulting dilution)
will be ignored and the number of additional Shares to be issued to University will be calculated assuming Company had raised only such amount of equity capital as would result in its cumulative equity capital raised since incorporation being equal
to the Qualified Offering Proceeds. Any such additional Shares will be issued as of or immediately after such closing.

 A3.5.1    Participation Rights. If the Company
proposes to sell any equity securities or securities that are convertible into equity securities of the Company (collectively, “Equity Securities”), then the University and/or its Assignee (as defined below) will have the right to
purchase up to [***] percent ([***]%) of the securities issued in each offering on the same terms and conditions as are offered to the other purchasers in each such financing. Company shall provide ten business days advanced written notice of each
such financing, including reasonable detail regarding the terms and purchasers in the financing. If all Equity Securities that the University and/or its Assignee are entitled to purchase pursuant to this Subsection A3.5.1 are not elected to be
purchased by the University and/or its Assignee during such ten business day period, the Company may offer the remaining unsubscribed portion of such Equity Securities to any person or persons at a price not less than that, and upon terms no more
favorable to the offeree than those, specified in such written notice. The term “Assignee” means (a) any entity to which the University’s participation rights under this section have been assigned either by the University
or another entity, or (b) any entity that is controlled by the University. Notwithstanding the foregoing, the foregoing participation rights shall not apply to the following: (i) the issuance or sale of Shares or options therefor, to
employees, directors, consultants and other service providers for the primary purpose of soliciting or retaining their services pursuant to plans or agreements approved by the Company’s Board of Directors (the “Board”); (ii)
the issuance of securities pursuant to the conversion or exercise of convertible or exercisable securities that are outstanding as of the date hereof; (iii) the issuance of securities in connection with a bona fide business acquisition by the
Company, whether by merger, consolidation, sale of assets, sale or exchange of stock or otherwise, approved by the Board; (iv) the issuance of stock, warrants or other securities or rights pursuant to any equipment leasing arrangement or debt
financing arrangement, which arrangement is approved by the Board and is primarily for non-equity financing purposes; (v) the issuance of stock, warrants or other securities or rights to persons or
entities with which the Company has business relationships, provided such issuances are approved by the Board and are primarily for non-equity financing purposes; (vi) the issuance of Equity Securities
that are specifically deemed (in a written instrument) not to be subject to the participation rights set forth in this Subsection A3.5.1 by the University and/or its Assignee; or (vii) the issuance of any other Equity Securities that are
excluded from any right of first offer or participation right granted by the Company to any of its investors and set forth in an “Investors’ Rights Agreement” or any similar agreement at any time then-outstanding. In addition to the
foregoing, this participation right shall not be applicable with respect to any Assignee in any subsequent offering of Equity Securities if (x) at the time of such offering, Assignee is not an “accredited investor,” as that term is
then defined in Rule 501(a) of the Securities Act of 1933, as amended, and (y) such offering of Equity Securities is otherwise being offered only to accredited investors. This paragraph shall survive the termination of this Agreement. 

A3.6    Sublicense Consideration. Within [***] days of the end of each calendar quarter during the
term of this Agreement, Company will pay to University [***] percent ([***]%) of any Sublicense Consideration received by Company during such calendar quarter unless reduced by achievement of milestones by Company or its Sublicensees prior to
execution of the particular Sublicense in accordance with the schedule below; provided that if the nature of the sublicense is a co-development agreement where Company remains involved in the funding and/or
conduct of the development, then the percentage of Sublicense Consideration will be based on status of the molecular entity (agonist in A2.1, [***] molecule in A2.2, or antagonist in A2.3) at the time the Sublicense Consideration payment is received
by Company. Determination of the relevant Performance Milestone having been achieved for the purposes of determining the Sublicense Consideration percentage shall be based on the milestones achieved by the most advanced molecular entity under
development by Company that is the same type of molecular entity as the Licensed Product then in development for which Sublicense Consideration was received. A reduction of the percentage of Sublicense Consideration payable to University under this
Agreement will be negotiated in good faith between the Parties where, in addition to the Sublicense of any rights granted to Company hereunder, Company or its Sublicensee also grants a Sublicensee a license under a Third Party’s intellectual

 Exhibit C 

STOCK SUBSCRIPTION AGREEMENT 

STOCK SUBSCRIPTION AGREEMENT, dated the date indicated below on the signature page hereof, by and between the Company and the
University. If and when accepted by the Company, this Stock Subscription Agreement, when executed below, shall constitute a subscription for that number of shares of the Securities indicated on the attached Appendix A. All capitalized terms are
defined on Appendix A. 
 INTENDING TO BE LEGALLY BOUND, and in consideration of the mutual representations, warranties,
covenants and agreements contained herein, Company and University hereby agree as follows: 

1.    Representations and Warranties of the University. The University hereby represents and
warrants to the Company as of the date of this Agreement as follows: 
 1.1    The University:
(a) is an Accredited Investor as that term is defined in 17 CFR § 230.501(a); (b) has been furnished with all information deemed necessary by the University to evaluate the merits and risks of the Securities; (c) has had the
opportunity to ask questions and receive answers concerning the Company and the Securities; and (d) has been given the opportunity to obtain any additional information necessary to verify the accuracy of any information obtained concerning the
Company. 
 1.2    Ability to Bear Risk. The University is in a financial position to hold the
Securities and is able to bear the economic risk and withstand a complete loss of the investment in the Securities. 

1.3    Risk Factors. The University recognizes that the Securities as an investment involve an
extremely high degree of risk. There can be no assurance that the Company will be able to meet its projected goals and the Company may need significant additional capital to be successful, which capital may not be readily available or available upon
terms that are not substantially dilutive to the University. If provided, the University has reviewed the risk factors description provided by the Company. 

1.4.    Sophistication. The University is a sophisticated investor, is able to fend for itself in
the transactions contemplated by this Agreement, and has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the prospective investment in the Securities. 

1.5.    Suitability. The investment in the Securities is suitable for the University based upon its
investment objectives and financial needs, and the University has adequate net worth and means for providing for its current financial needs and contingencies and has no need for liquidity of investment with respect to the Securities. 

1.6.    Overall Commitment to Illiquid Investments. The University’s overall commitment to
investments which are illiquid or not readily marketable is not disproportionate to its net worth, and investment in the Securities will not cause such overall commitment to become excessive.

 1.7.    Restricted Securities. The University
realizes that (i) none of the Securities have been registered under the Securities Act of 1933, as amended (the “Act”), (ii) the Securities are characterized under the Act as “restricted securities” and,
therefore, cannot be sold or transferred unless they are subsequently registered under the Act or an exemption from such registration is available and (iii) there is presently no public market for the Securities and the University may not be
able to liquidate his investment in the event of an emergency or pledge the Securities as collateral security for loans. In this connection, the University represents that it is familiar with Rule 144 promulgated under the Act, and understands the
resale limitations imposed thereby and by the Act. 
 1.8.    Exemption Reliance. The University
has been advised that the Securities are not being registered under the Act or the applicable state securities laws but are being offered and sold pursuant to exemptions from such laws. The University understands that the Company’s reliance on
such exemptions is predicated in part upon the truth and accuracy of the University’s representations in this Agreement. The University represents and warrants that the Securities are being acquired for its own account, in fulfillment of its
statutory mandate for the commercialization of research and economic development under RCW 28B.10.630, and without the intention of reselling, redistributing or transferring the same, that it has made no agreement with others regarding any of such
Securities and that its financial condition is such that it is not likely that it will be necessary to dispose of any of such Securities in the foreseeable future. 

2.    Covenants. The University agrees that: 

2.1.    Transfer Restriction. The Securities for which the University hereby subscribes shall be
assigned or transferred only in accordance with all applicable laws. 
 2.2.    Disposition of
Securities. The University shall in no event make any disposition of all or any portion of the Securities which it is purchasing unless and until: 

a.    There is then in effect a registration statement under the Act covering such proposed disposition
and such disposition is made in accordance with said registration statement; or 
 b.    (i) It
shall have furnished the Company with an opinion of its own counsel to the effect that such disposition will not require registration of such shares under the Act, and (ii) such opinion of its counsel shall have been concurred in by counsel for
the Company, such concurrence not to be unreasonably withheld or delayed, and the Company shall have advised the University of such concurrence; or 

c.    The transfer shall comply with the applicable requirements of Rule 144 as promulgated under
the Securities Act of 1933, as amended, or is otherwise exempt from the registration requirements of such act. 

2.3.    No Revocation. The University may not cancel, terminate or revoke this subscription, and
this subscription shall be binding upon its successors and assigns.

and class of Securities as the University) 


  

	 	•	 	 Confidentiality restrictions or limitations that purport to prevent the University from complying with
applicable open records requirements. 


 3.    Issuance of Stock Certificate.

4.    Governing Law; Successors. The University agrees that this Subscription Agreement shall be
enforced, governed and construed in all respects in accordance with the laws of the State of Washington, that the rights, powers and duties set forth herein shall be binding upon the University, its successors and assigns, and shall inure to the
benefit of its successors and assigns. 
 THE UNIVERSITY HAS BEEN ADVISED, PRIOR TO ITS PURCHASE OF THE SECURITIES, THAT
NEITHER THE OFFERING OF THE SECURITIES NOR ANY OFFERING MATERIALS HAVE BEEN REVIEWED BY ANY ADMINISTRATOR UNDER THE ACT OR ANY OTHER APPLICABLE SECURITIES ACT (THE “ACTS”) AND THAT NONE OF THE SECURITIES HAVE BEEN REGISTERED UNDER
ANY OF THE ACTS AND THEREFORE CANNOT BE RESOLD UNLESS THEY ARE REGISTERED UNDER THE ACTS OR UNLESS AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.
