 8.5    Royalty Reduction. The amount of royalties payable
by Brii Bio pursuant to Section 8.4 shall be reduced in the following circumstances: 
 (a)    [***] 

(b)    [***] 

(c)    [***] 

(d)    [***] 

8.6    Royalty Payments and Reports. Within [***] after the end of each [***], Brii Bio shall make all
royalty payments payable to AN2 under this Article 8 with respect to such [***]. Along with such payments, Brii Bio shall also provide a report containing the following information for the applicable [***], on a Licensed Product-by-Licensed Product and Region-by-Region basis: [***] (the “Royalty
Report”). 
 8.7    No Projections or Guaranteed Payment. 

(a)    Each Party acknowledges and agrees that nothing in this Agreement shall be construed as representing an estimate or
projection of anticipated sales of any Licensed Product and that the milestone events and Net Sales levels set forth above or that have otherwise been discussed by the Parties are merely intended to define the milestone events and royalty
obligations to AN2 if such milestone events or Net Sales levels are achieved. 
 (b)    AN2 expressly acknowledges and
agrees that it may not receive and, absent the achievement of a milestone event in Section 8.2 or Section 8.3, or the achievement of Net Sales of a Licensed Product, will not be entitled to receive any further payments hereunder (including
any milestone payments or royalties) other than: (i) the equity investment in Section 8.1(a) and (ii) such other costs to be paid by Brii Bio for Manufacturing of Licensed Products as set forth in Section 7.2. The Parties
expressly acknowledge and agree that the milestone payments and royalties are contingent upon satisfaction of conditions provided for herein that may not be satisfied, and as a result, some or all of such payments may not become obligations of Brii
Bio (or its assigns) and may therefore never be paid. AN2 expressly acknowledges that: (A) the equity investment in Section 8.1(a); (B) such other costs to be paid by Brii Bio for Manufacturing of Licensed Products as set forth in
Section 7.2; and (C) the possibility of receiving milestone payments and royalties in accordance with the terms set forth herein constitute sufficient consideration for entering into this Agreement. Neither Party has made any
representation or warranty to the other that any such conditions will be satisfied. Accordingly, if such conditions to any payments are not satisfied, no Party will have any recourse against the other Party hereunder unless there is an independent
breach of this Agreement.

 ARTICLE 9 

PAYMENTS, BOOKS AND RECORDS 

9.1    Payment Method. All payments to AN2 under this Agreement shall be made by bank wire transfer in
immediately available funds to an account in the name of AN2 designated in writing by AN2. Payments hereunder shall be considered to be made as of the day on which they are received by AN2’s designated bank. 

9.2    Payment Currency; Currency Conversion. 

(a)    United States Dollars. Unless otherwise expressly stated in this Agreement, all amounts specified to
be payable under this Agreement are in Dollars and shall be paid in Dollars. 
 (b)    Currency Conversion. For
the purpose of computing the Net Sales for any Licensed Product sold in a currency other than Dollars and for purposes of determining Net Sales and development costs, or other shared expenses under this Agreement incurred by a Party in a currency
other than Dollars, such Net Sales or costs amounts shall be converted into Dollars each quarter using an exchange rate that is the arithmetic average of the daily exchange rates (obtained as described below) during such quarter. Each daily exchange
rate shall be obtained from The Wall Street Journal, Eastern United States Edition, or, if not so available, as otherwise agreed by the Parties. 

(c)    Blocked Currency. Notwithstanding the provisions of Section 9.2, if by Applicable Law of a
Region, conversion into Dollars or transfer of funds of a convertible currency to the United States is restricted, forbidden or substantially delayed, then Brii Bio shall promptly notify AN2 and, thereafter, amounts accrued in such Region shall be
paid to AN2 in such Region in local currency by deposit in a local bank designated by AN2 for a period no longer than [***], after which any payments due to AN2 shall be paid in Dollars, unless the Parties otherwise agree. 

9.3    Taxes. 

(a)    Cooperation and Coordination. The Parties acknowledge and agree that it is their mutual objective and intent
to minimize, to the extent feasible, income and other taxes, including withholding taxes, and similar obligations payable with respect to their collaborative efforts under this Agreement and that they shall use their reasonable efforts to cooperate
and coordinate with each other to achieve such objective. Each Party shall provide the other Party any tax forms that may be reasonably necessary in order for the Party making a payment (the “Paying Party”) to the other Party (the
“Non-Paying Party”) under this Agreement not to withhold tax or deduct an amount of Transfer Taxes or to withhold tax or deduct Transfer Taxes at a reduced rate under an applicable bilateral
income tax treaty or otherwise. Each Party shall use reasonable efforts to identify any such forms prior to the due date for such payment, and the Non-Paying Party shall use reasonable efforts to provide any
such forms to the Paying Party in advance of such date. Each Party shall provide the other with reasonable assistance to enable the recovery, as permitted by Applicable Law, of withholding taxes, Transfer Taxes or similar obligations resulting from

payments made under this Agreement, such recovery to be for the benefit of the Party with respect to which such amount was withheld or deducted (or, if the amount was not withheld or deducted,
the Party that actually bore the economic cost of the tax that is recovered). 
 (b)    Payment of Tax. Except as
otherwise set forth in this Section 9.3, each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the activities of the Parties under this Agreement. If Applicable
Law requires that taxes be deducted and withheld from a payment, the Paying Party shall (i) deduct those taxes from the payment; (ii) timely pay the taxes to the proper taxing authority; and (iii) send evidence of the obligation
together with proof of payment to the other Party within thirty (30) days following that payment. 

9.4    Records. Brii Bio shall keep, and cause its Affiliates and Sublicensees to keep, complete, true and
accurate books of accounts and records of all data in sufficient detail for the purpose of determining, in a manner consistent with GAAP, the amounts payable to AN2 pursuant to this Agreement. Such books and records shall be kept for such period of
time required by Applicable Law, but no less than at least [***] following the end of the year to which they pertain. Such records shall be subject to inspection in accordance with Section 9.5. 

9.5    Audits. Upon not less than [***] prior written notice, Brii Bio shall permit an independent,
certified public accountant selected by AN2 and reasonably acceptable to Brii Bio, which acceptance will not be unreasonably withheld or delayed (for the purposes of this Section 9.5, the “Auditor”), to audit or inspect those
books or records of Brii Bio or its Affiliates that relate to Net Sales and Royalty Reports for the sole purpose of verifying the: (a) royalties payable hereunder in respect of Net Sales; (b) withholding taxes, if any, required by
Applicable Law to be paid by Brii Bio in respect of such Net Sales; and (c) exchange rates used in determining the amount of Dollars. Such Auditor shall be under reasonable written obligations of confidentiality to the audited Party and shall
disclose to AN2 only the amount and accuracy of payments reported and actually paid or otherwise payable under this Agreement. The Auditor shall send a copy of the report to Brii Bio at the same time it is sent to AN2. Such inspections may be made
no more than once each Calendar Year and during normal business hours. [***]. The results of such audit shall be final and binding, absent manifest error. 

9.6    Late Payments. In the event that any payment due under this Agreement is not made when due, the
payment shall accrue interest from the date due at a rate per annum equal to [***] above the U.S. Prime Rate (as set forth in the Wall Street Journal, Eastern Edition) for the date on which payment was due, calculated daily on the basis of a
three hundred and sixty-five (365)-day year, or similar reputable data source; provided that, in no event shall such rate exceed the maximum legal annual interest rate.

(the “Receiving Party”) shall keep confidential and shall not publish or otherwise disclose or use for any purpose other than the performance of its obligations or exercise of
its rights under this Agreement any confidential or proprietary information and materials, patentable or otherwise, in any form (written, oral, photographic, electronic, magnetic or otherwise) that is disclosed to it by the other Party (the
“Disclosing Party”) including, but not limited to, all Know-How, Inventions and any other technical, regulatory or business information of whatever nature (collectively, “Confidential
Information”). 
 10.2    Exceptions. Notwithstanding Section 10.1 above, the obligations of
confidentiality and non-use shall not apply to Confidential Information to the extent that such Confidential Information, in each case as demonstrated by competent evidence: 

(a)    was already known by the Receiving Party or any of its Affiliates, other than under an obligation of
confidentiality, at the time of disclosure; 
 (b)    was generally available to the public or was otherwise part of the
public domain at the time of its disclosure to the Receiving Party; 
 (c)    became generally available to the public
or otherwise part of the public domain after its disclosure by the Disclosing Party and other than through any act or omission of the Receiving Party or any of its Affiliates or disclosees in breach of this Agreement; 

(d)    was subsequently lawfully disclosed to the Receiving Party or any of its Affiliates by a Person other than the
Disclosing Party, and who did not directly or indirectly receive such information directly or indirectly from the Disclosing Party under an obligation of confidence; or 

(e)    was independently developed by the Receiving Party or its Affiliate without use of or reference to any information
or materials disclosed by the Disclosing Party. 
 10.3    Permitted Disclosures. Notwithstanding the
provisions of Section 10.1, each Party may disclose Confidential Information belonging to the other Party as expressly permitted by this Agreement or if and to the extent such disclosure is reasonably necessary in the following instances:

reasonable assistance in obtaining a protective order or confidential treatment preventing or limiting the disclosure and/or requiring that the Confidential Information so disclosed be used only
for the purposes for which the law or regulation required or for which the order was issued; 
 (e)    to those of its
employees, Affiliates, contractors or agents who have a need to know such Confidential Information in order to enable the Receiving Party to carry out its obligations or exercise its rights pursuant to this Agreement; provided, that such
persons are subject to obligations of confidentiality and non-use at least equivalent in scope to the obligations set forth in this Article 10; 

(f)    to existing or potential acquirers or merger candidates; (sub)licensees; investment bankers; existing or potential
investors, venture capital firms or other financial institutions or investors for purposes of obtaining financing; or other commercial partners, each of whom prior to disclosure must be bound by obligations of confidentiality and non-use at least equivalent in scope to those set forth in this Article 10; and advisors; provided, however, that, (i) neither Party shall make such disclosure to a Competitor of the other Party
without first obtaining the non-Disclosing Party’s prior written consent unless such Competitor is a bona fide acquirer or investor of the Disclosing Party and, in connection with such acquisition or
investment, has requested information specific to the Licensed Territory, in which case the Disclosing Party shall promptly notify the other Party of such disclosure and shall ensure that such disclosure is subject to confidentiality and non-use obligations at least equivalent in scope to those set forth in this Article 10, and (ii) each Party will remain responsible for any failure by any of the foregoing individuals to treat such Confidential
Information as required under Section 10.1 as if such individuals were parties directly bound to the requirements of this Article 10. For purposes of this Section 10.3(f), “Competitor” shall mean (x) with respect to
Brii Bio, a pharmaceutical or biotechnology company engaged in the development or commercialization of Competing Compounds in the Licensed Territory, where such development activities in the Licensed Territory comprise a material portion of such
company’s global business, and (y) with respect to AN2, a biotechnology company engaged in the development or commercialization of Competing Compounds in the AN2 Territory. 

Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s Confidential Information, it
shall, except where impracticable, give reasonable advance notice to the other Party of such disclosure and use efforts to secure confidential treatment of such information at least as diligent as such Party would use to protect its own confidential
information, but in no event less than reasonable efforts; provided, that any Confidential Information so disclosed shall still be subject to the restrictions on use set forth in this Article 10. In any event, the Parties agree to take all
reasonable action to avoid disclosure of Confidential Information hereunder. 
 10.4    Confidentiality of
this Agreement and its Terms. Except as otherwise provided in this Article 10, each Party agrees not to disclose to any Third Party the existence of this Agreement or the terms of this Agreement without the prior written consent of the other
Party hereto, which Agreement and terms shall be deemed the Confidential Information of both Parties.

 10.5    Public Announcements and Filings. Following
the Effective Date hereof, each Party shall have the right to issue a press release announcing the existence of this Agreement; provided that the non-issuing Party has approved such press release in
writing. For greater certainty, neither Party (nor its Affiliates) shall be obligated to consult with or obtain approval from the other Party with respect to any filings to the SEC, the NASDAQ stock exchange or any other stock exchange or
Governmental Authority; provided that a Disclosing Party shall give [***] advance notice to the other Party of such disclosure and use efforts to secure confidential treatment of such information at least as diligent as such Party would use
to protect its own confidential information. 
 10.6    Prior
Non-Disclosure Agreements. As of the Effective Date, the terms of this Article 10 shall supersede any prior non-disclosure, secrecy or confidentiality agreement
between the Parties (or their Affiliates) dealing with the subject of this Agreement, including without limitation the Confidentiality Agreement. Any information disclosed under such prior agreements shall be deemed as Confidential Information
disclosed under this Agreement.

trademark, trade name or logotype of the other Party only: (a) in connection with permitted disclosures relating to this Agreement and the activities contemplated hereby; (b) as required by Applicable Law, or (c) as otherwise
expressly permitted by this Agreement or agreed in writing by such other Party; provided that each Party shall use the other Party’s name, insignia, symbol, trademark, trade name or logotype only in such manner that the distinctiveness,
reputation and validity of any trademarks and corporate or trade names of such other Party shall not be impaired, and consistent with best practices used by such first Party for its other collaborators. 

10.8    Publication. At least [***] prior to publishing, publicly presenting and/or submitting for written
or oral publication a manuscript, abstract or the like that includes information relating to any Global Development Plan, Brii Bio Development Plan, Patent or Invention that has not been previously published, each Party shall provide to the other
Party a draft copy thereof for its review. The publishing Party shall consider in good faith any comments provided by the other Party during such [***] period. In addition, the publishing Party shall, at the other Party’s reasonable request,
remove therefrom any Confidential Information of such other Party. If requested in writing by the non-publishing Party, the publishing Party shall withhold material from submission for publication or
presentation for an additional [***] to allow for the filing of a Patent application or the taking of such other measures as may be required to establish and preserve proprietary rights in the information in the material being submitted for
publication or presentation. The contribution of each Party shall be noted in all publications or presentations by acknowledgment or co-authorship, whichever is appropriate.

of such filing, prosecution and maintenance of such AN2 Patent or Joint Patent by Brii Bio. 
 (ii)    If Brii Bio
elects not to prosecute or maintain any Joint Patent in the Licensed Territory, Brii Bio shall provide reasonable prior written notice to AN2 of such intention (which notice shall, to the extent possible, be given no later than [***] prior to the

Patent by so notifying Brii Bio in writing. If AN2 assumes such responsibility for filing, prosecution and maintenance of such Joint Patent, then: (A) Brii Bio shall, and hereby does, assign all of its right, title and interest in and to such
Joint Patent to AN2; and (B) Brii Bio shall cooperate as reasonably requested by AN2 to facilitate control of such filing, prosecution and maintenance of such Joint Patent by AN2. 

(d)    Cooperation. Each Party shall provide the other Party with all reasonable assistance and cooperation
in the patent prosecution efforts set forth in this Section 11.2, including providing any necessary powers of attorney and executing any other required documents or instruments for such prosecution. 

11.3    Infringement by Third Parties. 

(a)    Notice. In the event that either AN2 or Brii Bio becomes aware of any infringement or threatened infringement
by a Third Party of the AN2 Patents or Joint Patents, which infringement adversely affects or is expected to adversely affect any Licensed Product in the Field in the Licensed Territory, or any related declaratory judgment, opposition or similar
action alleging the invalidity, unenforceability or non-infringement of any of the AN2 Patents or Joint Patents in the Licensed Territory (collectively, “Licensed Compound Infringement”), it
will notify the other Party in writing to that effect. Any such notice shall include any available evidence to support an allegation of infringement or threatened infringement by such Third Party. 

(b)    Licensed Territory. AN2 shall have the first right (but not the obligation), as between AN2 and Brii Bio, to
bring and control any action or proceeding with respect to Licensed Compound Infringement in the Licensed Territory. Brii Bio shall have the right, at its own expense, to be represented in any such action by counsel of its own choice, and Brii Bio
and its counsel will reasonably cooperate with AN2 and its counsel in strategizing, preparing and presenting any such action or proceeding. If AN2 fails to bring an action or proceeding with respect to such Licensed Compound Infringement in the
Licensed Territory: [***], then Brii Bio shall have the right (but not the obligation) to bring and control any such action at Brii Bio’s cost and expense, and AN2 shall have the right, at its own expense, to be represented in any such action
by counsel of its own choice; provided that, in the event the Person engaged in the Licensed Compound Infringement in the Licensed Territory is also engaged in such infringement in the AN2 Territory, and AN2 has commenced a suit to secure the
abatement of such infringement in the AN2 Territory, then AN2 shall promptly notify Brii Bio thereof and Brii Bio shall not have the right to commence such suit or action without the prior written consent of AN2, not to be unreasonably withheld,

 (c)    AN2 Territory. AN2 shall have the sole right to bring and
control any action or proceeding with respect to Licensed Compound Infringement in the AN2 Territory; provided, that AN2 shall keep Brii Bio reasonably informed of all steps with regard to any such infringement actions to the extent
relevant to Licensed Products in the Licensed Territory, including by providing Brii Bio with a copy of all proposed material filings and summaries of all material communications to and from any patent authority regarding such infringement
proceeding. Except as otherwise agreed to by the Parties as part of a cost-sharing arrangement, any recovery or damages realized as a result of such action or proceeding shall be retained by AN2. 

(d)    Cooperation. In the event a Party (the “Enforcing Party”) brings an infringement
action or proceeding in accordance with this Section 11.3, the other Party shall cooperate fully, including, if required to bring such action, the furnishing of a power of attorney or being named as a party to such action. The Enforcing Party
shall keep the other Party regularly informed of the status and progress of such enforcement efforts, and shall reasonably consider the other Party’s comments on any such efforts. The non-enforcing Party
shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense, but such Party shall at all times cooperate fully with the Enforcing Party. 

(e)    Expenses and Recoveries. The Enforcing Party shall be solely responsible for any expenses it incurs
as a result of any claim, suit or action brought by such Enforcing Party under Section 11.3(b), except that the Parties shall share equally the cost and expense of the enforcement action when AN2 is the Enforcing Party and Brii Bio elects to
join the enforcement action. If the Enforcing Party recovers monetary damages in such claim, suit or action brought under Section 11.3(b), such recovery shall be allocated first to the reimbursement of any documented expenses incurred by the
Parties in such enforcement action, and any remaining amounts shall be shared by the Parties as follows: 
 (i)    if
AN2 is the Enforcing Party and Brii Bio elects to join the enforcement action and share the cost and expenses related thereto: [***]; 

(ii)    if AN2 is the Enforcing Party and Brii Bio does not elect to join the enforcement action and share the cost and
expenses related thereto: [***]; 
 (iii)    if Brii Bio is the Enforcing Party: [***].

INDEMNIFICATION 

13.1    Indemnification of AN2. Brii Bio shall indemnify, defend and hold harmless AN2 and its
Affiliates and its and their directors, officers, employees and agents (the “AN2 Indemnitees”) from and against any and all losses, liabilities, damages, penalties, fines, costs and expenses (including reasonable attorneys’
fees and other expenses of litigation) (“Losses”) from any claims, actions, suits or proceedings brought by a Third Party (a “Third Party Claims”) incurred by any AN2 Indemnitee, to the extent arising from, or
occurring as a result of: (a) the Development, Manufacture, use, handling, storage, sale or other Commercialization of Licensed Product by Brii Bio or its Affiliates or Sublicensees in the Licensed Territory, including, without limitation,
product liability claims (but excluding claims resulting from AN2’s Manufacture of the Licensed Products); (b) gross negligence or willful misconduct by or on behalf of Brii Bio or its Affiliates in performing any activities in connection with
this Agreement; and (c) any breach of any representations, warranties or covenants by Brii Bio under this Agreement; except, in each case ((a)–(c)), to the extent such Third Party Claims fall within the scope of the indemnification
obligations of AN2 set forth in Section 13.2. 
 13.2    Indemnification of Brii Bio. AN2 shall
indemnify, defend and hold harmless each of Brii Bio and its Affiliates and its and their directors, officers, employees and agents of such entities (the “Brii Bio Indemnitees”) from and against any and all Losses from any Third
Party Claim incurred by any Brii Bio Indemnitee to the extent arising from, or occurring as a result of: (a) the Development, Manufacture, use, handling, storage, sale or other Commercialization of Licensed Products by AN2 or its Affiliates in
the AN2 Territory or in the Licensed Territory under a Global Development Plan or AN2 Global Clinical Trial; (b) gross negligence or willful misconduct by or on behalf of AN2 or its Affiliates in performing any activities in connection with
this Agreement; and (c) any breach of any representations, warranties or covenants by AN2 under this Agreement; except, in each case ((a)–(c)) to the extent such Third Party Claims fall within the scope of the indemnification obligations
of Brii Bio set forth in Section 13.1. 
 13.3    Procedure. A Party that intends to claim
indemnification under this Article 13 (the “Indemnitee”) shall promptly notify the indemnifying Party (the “Indemnitor”) in writing of any Third Party Claim in respect of which the Indemnitee intends to claim such
indemnification. The Indemnitee shall provide the Indemnitor with reasonable assistance, at the Indemnitor’s expense, in connection with the defense of the Third Party Claim for which indemnity is being sought. The Indemnitee may participate in
and monitor such defense with counsel of its own choosing at its sole expense; provided, however, the Indemnitor shall have the right to assume and conduct the defense of the Third Party Claim with counsel of its choice, which counsel
shall be reasonably acceptable to Indemnitee. The Indemnitor shall not settle any Third Party Claim without the prior written consent of the Indemnitee, not to be unreasonably withheld, delayed or conditioned, unless the only liability to the
Indemnitee is the payment of money and the Indemnitor makes such payment. So long as the Indemnitor is actively defending the Third Party Claim in good faith, the Indemnitee shall not settle any such Third Party Claim without the prior written
consent of the Indemnitee. If the Indemnitor does not assume and conduct the defense of the Third Party Claim as provided above: (a) the Indemnitee may defend against and consent to the entry of any judgment

or enter into any settlement with respect to the Third Party Claim in any manner the Indemnitee may deem reasonably appropriate (and the Indemnitee need not consult with, or obtain any consent
from, the Indemnitor in connection therewith); and (b) the Indemnitor will remain responsible to indemnify the Indemnitee as provided in this Article 13. The failure to deliver written notice to the Indemnitor within a reasonable time after the
commencement of any action with respect to a Third Party Claim shall only relieve the Indemnitor of its indemnification obligations under this Article 13 if and to the extent the Indemnitor is actually prejudiced thereby. 

13.4    Insurance. Each Party, at its own expense, shall maintain product liability and other appropriate
insurance (including D&O insurance) in an amount consistent with industry standards for a company in a similar position to such Party during the Term. Each Party shall provide the other Party with written notice at least [***] prior to any
cancellation, nonrenewal or material change in the insurance described above. Each Party shall provide a certificate of insurance evidencing such coverage to the other Party upon request. Each Party shall provide a certificate of insurance
evidencing its D&O insurance annually. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 13. 

13.5    No Third Party Beneficiary. Except for Anacor pursuant to Section 4.2, no Third Party is an
intended third-party beneficiary of this Agreement.

[***] following the effective date of Brii Bio’s request for such revised payment structure. For clarity, the Parties hereby agree and acknowledge that any renegotiation or arbitration to any financial terms pursuant to
Section 14.4(b)(iii) shall be subject to, and the Parties and/or arbitration tribunal shall fully take into account during such renegotiation or arbitration, the limitations of liability set forth in Section 13.6 with respect to any claims
to any indirect, punitive, special, incidental and consequential damages (including any claims for lost profits or revenues) arising under or in connection with this Agreement under any theory of liability. 

14.5    Effects of Termination by AN2 pursuant to Section 14.2(d).

terminate, including all sublicenses granted by Brii Bio unless such sublicenses are assumed by AN2 pursuant to Section 4.4, which shall survive such termination. AN2 shall have a reversion of all rights previously licensed to Brii Bio under
Section 4.1 for which the relevant licenses have terminated on a fully paid-up and royalty-free basis, itself or with or through an Affiliate or Third Party, to Develop and Commercialize the Licensed
Products in the Field in the Licensed Territory at AN2’s discretion. 
 14.6    General Effects of Termination.

 (a)    Multiple Remedies. Notwithstanding anything to the contrary in this Agreement, termination is
not the sole remedy under this Agreement, and all other remedies will remain available if any termination is affected.

containing Confidential Information of the Disclosing Party that are necessary for the Receiving Party to exercise any other license or right of the Receiving Party that survives such termination of this Agreement. 

14.7    Survival. Any expiration or termination of this Agreement shall not affect rights or
obligations of the Parties under this Agreement that have accrued prior to the date of expiration or termination. Notwithstanding anything to the contrary, the following provisions shall survive any termination of this Agreement: Sections 4.7,

Inventions that relate to the Licensed Product, as they exist as of the effective date of termination of the Anacor Agreement, to use, develop, commercialize and manufacture Licensed Compounds and Licensed Products. 

ARTICLE 15 
 DISPUTE
RESOLUTION AND GOVERNING LAW 
 15.1    Dispute Resolution Process. The Parties recognize that from
time to time, there may be disputes, controversies or claims arising out of or relating this Agreement. If the Parties cannot resolve any such dispute within [***] after written notice of a dispute from one (1) Party to another, either Party
may, by written notice to the other Party, have such dispute referred to the Senior Executives. The Senior Executives shall negotiate in good faith to resolve the dispute within [***]. During such period of negotiations, any applicable time periods
under this Agreement shall be tolled. If the Senior Executives are unable to resolve the dispute within such time period, then the dispute shall be resolved as follows: 

(a)    for final resolution of matters not referred to expert determination under Section 2.1 or
Section 5.1(f)(ii)(C), including disputes regarding whether a Party properly exercised its final decision-making authority under Section 5.1(f)(ii)(A) or Section 5.1(f)(ii)(B), by binding arbitration in accordance with
Section 15.2. Notwithstanding anything in this Article 15 to the contrary, AN2 and Brii Bio shall each have the right to apply to any court of competent jurisdiction for appropriate interim or provisional relief, as necessary to protect the
rights or property of that Party;

 (b)    for final resolution of matters designated under Section 2.1
and Section 5.1(f)(ii)(C), to be resolved by expert determination, in accordance with Section 15.3. 

15.2    Arbitration. 

(a)    If the Parties are unable to resolve such dispute through the procedures described in Section 15.1, then,
except in the case of a dispute, controversy or claim that concerns the validity or infringement of a patent, trademark or copyright, the dispute shall be finally resolved by expedited binding arbitration under the Rules of Arbitration of the
International Chamber of Commerce (the “ICC Rules”) before a tribunal of [***] independent and neutral arbitrators experienced in the pharmaceutical business; [***] nominated by AN2, [***] nominated by Brii Bio and [***] nominated
by the foregoing [***] Party-nominated arbitrators within [***] of the second Party-nominated arbitrator’s appointment. The Parties agree, pursuant to Article 30(2)(b) of the Rules of Arbitration of the International Chamber of Commerce, that
the Expedited Procedure Rules shall apply irrespective of the amount in dispute, except as modified herein. 

(b)    The seat, or legal place, of arbitration shall be New York City, New York. The arbitration shall be conducted in
the English language. Notwithstanding Section 15.4, the arbitration and this agreement to arbitrate shall be governed by Title 9 (Arbitration) of the United States Code. Based on the Request, Answer and Counterclaims (if any) and Reply (if any)
(each as defined under the ICC Rules), the tribunal shall determine whether any discovery process is necessary, and, if it is, the parameters of such process with the intent of resolving the arbitration as expeditiously as possible (e.g.,
limiting the number of depositions and the time discovery is permitted to take). The Parties and arbitrators shall employ procedures designed to resolve the conflict by arbitration within [***] of the dispute being referred for arbitration. Judgment
upon the award may be entered in any court of competent jurisdiction. The existence and contents of the arbitration shall be kept confidential by each Party except to the extent that disclosure may be required to fulfil a legal duty, protect or
pursue a legal right, or enforce or challenge an award in legal proceedings. 
 (c)    If a Dispute proceeds to
arbitration pursuant to the provisions of Sections 14.3(d) or 14.4 of the Agreement, the arbitration shall be conducted in accordance with the provisions of Section 15.2, except that the tribunal’s decision shall be rendered as follows:
(i) at the conclusion of the arbitration hearings, each Party shall submit one (1) proposal to the tribunal; and (ii) the tribunal shall accept only one (1) of the proposals submitted by the Parties (without making any changes to
such proposal) and render such proposal as the tribunal’s final decision. Notwithstanding anything to the contrary in the Agreement, the tribunal shall not have the authority to render any decision other than selecting one (1) of the
proposals submitted by a Party pursuant to this Section 15.2(c). 
 15.3    Expert Determination.
For final resolution of matters designated under Section 2.1 and Section 5.1(f)(ii)(C) to be resolved by expert determination, the Parties hereby agree that such decision shall be conducted expeditiously by an independent expert
selected unanimously by the Parties. Either Party may initiate the expert determination by giving written notice to the other Party. If the Parties are unable to agree upon an expert within [***] after receipt of the notice of request for an expert
determination, then, the ICC International Centre for ADR

communications with either Party concerning the expert determination or the underlying dispute. The Parties agree to cooperate fully in the expeditious conduct of such expert determination and to provide the expert with access to all facilities,
books, records, documents, information and personnel necessary to make a fully informed decision in an expeditious manner. Before issuing a final decision, the expert shall issue a draft report and allow the Parties to the dispute to comment on it.
The expert shall endeavor to resolve the dispute within [***] after his or her appointment, taking into account the circumstances requiring an expeditious resolution of the matter in dispute. The expert’s decision shall be final and binding on

ARTICLE 16 
 GENERAL
PROVISIONS 
 16.1    Force Majeure. Neither Party shall be held liable or responsible to the other
Party or be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement to the extent such failure or delay is caused by or results from events beyond the reasonable control
of the non-performing Party, including fires, floods, earthquakes, extreme weather, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not) or terrorism, insurrections,
riots, civil commotion, strikes, lockouts or other labor disturbances, acts of God or acts, omissions or delays in acting by any Governmental Authority (each of the foregoing, a “Force Majeure Event”). The non-performing Party shall notify the other Party of such Force Majeure Event within ten (10) days after such occurrence by giving written notice to the other Party stating the nature of the event, its
anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is necessary and the non-performing
Party shall use Commercially Reasonable Efforts to remedy its inability to perform; provided, however, that in the event the suspension of performance continues for sixty (60) days after the date of the occurrence, the Parties shall meet
to discuss in good faith how to proceed in order to accomplish the goals outlined in this Agreement. 

16.2    Waiver of Breach. Any waiver of any provision of this Agreement shall be effective only if in
writing (specifying the provision so waived) and signed by the Party to be charged. No delay or waiver by either Party of any condition or term in any one (1) or more instances shall be construed as a further or continuing waiver of such
condition or term or of another condition or term.

in such jurisdiction.

 16.8    Assignment. This Agreement shall not be assigned or
otherwise transferred, nor may any right or obligations hereunder be assigned or transferred, by either Party without the prior written consent of the other Party; except that either Party may assign or otherwise transfer this Agreement without the
consent of the other Party (a) to an Affiliate; or (b) to a successor in interest that acquires all or substantially all of the business, stock or assets of the assigning Party relating to the subject matter of this Agreement, whether by
merger, consolidation, acquisition or otherwise. Subject to the foregoing, this Agreement shall inure to the benefit of each Party, its successors and permitted assigns. Any assignment of this Agreement in contravention of this Section 16.8

 16.9    Acquisition Affiliates. Notwithstanding anything to the contrary set

acquiring such Third Party, whether by merger, stock purchase, or purchase of assets, such Party (or Affiliate of a Party, as applicable) will not be deemed to Control any Know-How, Patents, Marketing
Approval, Regulatory Documentation, regulatory data, or other intellectual property rights of such Third Party (or such Third Party’s pre-Change of Control or
pre-acquisition affiliates) where (i) such Know-How, Patents, Marketing Approval, Regulatory Documentation, regulatory data, or other intellectual property rights
are owned or in-licensed by such Third Party (or its pre-Change of Control or pre-acquisition affiliate) prior to becoming an
Affiliate of such Party or developed by such Third Party (or its pre-Change of Control or pre—acquisition affiliate) entirely independent of this Agreement and the technology of such Party (and its
Affiliates) undergoing such transaction and without use, practice or reference to the Patents, Know-How and other materials licensed to a Party hereunder, and (ii) such
Know-How, Patents, Marketing Approval, Regulatory Documentation, regulatory data, or other intellectual property rights were not Controlled by such Party (or Affiliate of a Party, as applicable) prior to such
Change of Control or acquisition. For clarity, in the event such Third Party (or its pre-Change of Control or pre-acquisition affiliate) performs under this Agreement or
practices any of the Patents, Know-How or other materials licensed by the Parties hereunder, or the Party (or its Affiliate) for such Change of Control or acquisition transaction uses the Know-How, Patents, Marketing Approval, Regulatory Documentation, regulatory data, or other intellectual property rights of such Third Party (or such Third Party’s
pre-Change of Control or pre-acquisition affiliates) in performance hereunder, then the foregoing shall be deemed to be “Controlled” by such Party for purposes
hereof. 
 16.10    Relationship of the Parties. The Parties shall be independent contractors of one
another and nothing in this Agreement or any action that may be taken pursuant to its terms is intended, or shall be deemed, to establish a partnership, joint venture or agency between the Parties. Neither Party shall have the authority to make any
statements, representations or commitments of any kind, or to take any action, which shall be binding on the other Party. All persons employed by a Party shall be employees of such Party and not of the other Party and all costs and obligations
incurred by reason of any such employment shall be for the account and expense of such Party.
