 7.4    Third Party Obligations and Agreement Payments and Generic
Covered Products. The following adjustments shall be made, on a country-by-country and Covered
Product-by-Covered Product basis, to the royalties payable pursuant to Article 7.2: 

(a)    Third Party Patents. If it is [***] for Terns to license one or more Patents from one or more Third Parties
in order to Develop, Manufacture, Commercialize or use any Covered Product without infringing on a Third Party Patent, whether directly or through any Tern’s Affiliate or Sublicensee, then Terns may, in its sole discretion, negotiate and obtain
a license under such Patents (each such Third Party license referred to herein as an “Additional Third Party License”). Prior to executing any Additional Third Party License, Terns shall discuss and consult with Lilly
regarding such Additional Third Party License; provided that Terns retains full discretion over the decision to enter into, and the final terms of, any such Additional Third Party Licenses. Any [***] payable to Lilly under this Agreement [***] shall
be reduced by [***] of the amounts payable to Third Parties pursuant to any Additional Third Party Licenses, such reduction to continue until all such amounts have been expended, provided that in no event shall the [***] payable to Lilly [***] be
less than [***]. 
 (b)    No Adjustment for Lilly Third Party Agreements. Lilly shall be solely responsible for
(i) all obligations (including any royalty or other obligations that relate to the Lilly Technology) under its agreements with Third Parties that are in effect as of the Effective Date and (ii) all payments to inventors (other than
inventors that are employees or consultants of Terns) of Lilly Technology, including inventorship compensation payments under Applicable Law. 

(c)    No Adjustment for Existing Terns Third Party Agreements. Terns shall be solely responsible for all
obligations (including royalty obligations) that relate to Covered Products under its agreements with Third Parties that are in effect on or prior to the Effective Date. 

(d)    Failure to Pay. If Lilly should fail to pay any undisputed amounts owed under its agreements with Third
Parties under Article 7.4(b), Terns may at its sole option decide to pay any such amount and deduct such amount from any payments or royalties owed to Lilly hereunder without restriction. 

(e)    Generic Covered Products — Royalty Reduction. In the event it is reasonably determined that the total
volume sales of all Generic Covered Products with respect to such Covered Product in such country in the Territory in a Calendar Quarter constitutes (i) [***] of all such Generic Covered Products and such Covered Product in such country in the
Territory in such Calendar Quarter, then, during the Royalty Term, Lilly’s royalty rates as set forth in Article 7.2 of this Agreement shall be reduced by [***] commencing on the first calendar quarter that follows the date in which such
determination occurs or (ii) [***] of all such Generic Covered Products and such Covered Product in such country in the Territory in such Calendar Quarter, then, during the Royalty Term, Lilly’s royalty rates as set forth in Article 7.2 of this
Agreement shall be reduced by [***] commencing on the first calendar quarter that follows the date in which such determination occurs. 

(f)    Limit on Royalty Reductions. Notwithstanding anything to the contrary in this Article in no event shall the
royalties owed under Article 7.2 with respect to a Covered Product in a country be reduced by operation of any subsection of this Article 7.4 by more than an aggregate of [***] of what would otherwise be owed under Article 7.2 with respect to [***].

 7.5    Audits. 

(a)    Terns will keep and maintain (and to the extent applicable, will cause its Affiliates, and their respective
Sublicensees, distributors, assignees and transferees to keep and maintain) proper and complete records and books of account in such form and detail as is necessary for the determination of the amounts payable by Terns (on behalf of itself and its
Affiliates and their respective Sublicensees, distributors, assignees and transferees) to Lilly under this Agreement and for the purposes of this Agreement. 

(b)    Within the Term of this Agreement, Lilly shall not more than [***], have the right to have a reputable globally
recognized independent certified public accountant firm hired by Lilly to inspect Terns’ records for [***] for the purpose of determining the accuracy of royalty and milestone payments. No period will be audited more than once. Lilly shall
submit an audit plan, including audit scope, to Terns for Terns’ approval, which shall not be unreasonably withheld, prior to audit implementation. The independent certified public accountants shall keep confidential any information obtained
during such inspection and shall report to Lilly and Terns only the amounts of Net Sales and royalties and milestones due and payable. If determined that additional royalties or milestones are owed, or that royalties or milestones were overpaid,
during such period, Terns will pay Lilly the additional royalties or milestones, or Lilly will pay Terns the overpaid royalties or milestones within [***] of the date the independent certified public accountants written report is received by the
paying party. The fees charged by such accounting firm will be paid by Lilly unless any additional royalties or milestones owed exceed [***] of the royalties or milestones paid for the period subject to the audit, in which case Terns will pay the
reasonable fees of the accounting firm. 
 (c)    Terns shall include in each sublicense granted by it pursuant to this
Agreement a provision requiring the Sublicensee to make reports to Terns, to keep and maintain records of sales made pursuant to such sublicense [***]. 

(d)    Lilly shall treat all financial information subject to review in accordance with Article 9 of this Agreement, and
shall cause its accounting firm to enter into an acceptable confidentiality agreement with them [***] obligating it to retain all such information in confidence pursuant to terms consistent with the terms in Article 9 of this Agreement. 

7.6    Currency. Except as otherwise provided in this Agreement, all payments to be made by one Party to the other
under this Agreement shall be made in U.S. Dollars by bank wire transfer from such Party’s bank account in immediately available funds to the receiving Party’s bank account designated in writing by the Party receiving the payment. Sales,
costs and expenses, and payments recorded in any foreign currency shall be converted into U.S. Dollars in a manner consistent with Terns’ and Lilly’s customary and usual conversion procedures used to prepare such Party’s audited
financial statements, provided always that such practices are consistently applied and use a widely accepted source of published exchange rates. In each country where the local currency is blocked and cannot be removed from the country, payments
under this Agreement arising from activities in that country for which Licensee, an Affiliate thereof, or any Sublicensee does not receive payment in U.S. currency, freely useable outside of such country, shall, [***]. 

7.7    Interest. Each Party shall pay interest on any amounts overdue under this Agreement at a per annum rate of
[***] the average of the prime rate as published in the Wall

BEEN OMITTED BECAUSE IT (I) IS NOT MATERIAL AND (II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED] 

 
Street Journal during the thirty (30) days immediately preceding the due date of such overdue payment. Royalties and other payments required to be paid pursuant to this Agreement shall, if
overdue, bear interest from the day the original payment was due until the day that the payment was received by the payee. The payment of such interest shall not foreclose a Party from exercising any other rights it may have because any payment is
overdue. 
 7.7    Tax Withholding. If any payments required to be made by a Party under this Agreement
are or become subject to withholding taxes (including any value added tax) under Applicable Laws of any state, federal, provincial or foreign government, such Party shall be authorized to withhold such taxes as are required under Applicable Law, pay
such taxes to the appropriate Governmental Authority, deduct them from such payments, and remit the balance due to the other Party net of such taxes. The Party paying the taxes to the Governmental Authority shall secure and deliver to the other
Party an official receipt for taxes paid. In the event that the governing tax authority retroactively determines that a payment pursuant to this Agreement should have been subject to withholding (or to additional withholding) for taxes, and a Party
(the “Withholding Party”) remits such taxes to the tax authority, the Withholding Party will invoice the other Party for such amount, and the other Party will pay such amount within [***] of the receipt of such invoice.
Notwithstanding the foregoing, if Terns sublicenses or assigns its payment obligations to an Affiliate or to a third-party, and such sublicense or assignment results in a greater amount of withholding tax which may be subtracted from payments to
Lilly than if Terns had fulfilled its payment obligations to Lilly directly, such Affiliate or third-party shall increase the payment to Lilly as necessary such that the amount received by Lilly after such required income tax withholding is equal to
the amount Lilly would have received if Terns had fulfilled such payment obligations to Lilly directly. For clarity, Terns (including its affiliates, assignees, and sub-licensees) is solely responsible for any
income tax due in connection with its income under this Agreement. 
 7.8    Tax Administration. The Parties
agree to fully cooperate with each other to enable each Party to more accurately determine its own tax liability and to minimize such liability to the extent legally permissible and administratively reasonable. Each Party shall provide and make
available to the other Party any exemption certificates, resale certificates, or other required tax forms reasonably requested by the other Party to support the provisions of this Agreement. 

7.9    Records. Terns shall maintain appropriate records in either tangible or electronic form of (a) all
significant Development, Manufacturing and Commercialization (each as applicable) events and activities conducted by it or on its behalf related to the Covered Product; and (b) all significant information generated by it or on its behalf in
connection with Development of the Covered Product under this Agreement, in each case in accordance with Terns’ usual documentation and cGMP record retention practices. Such records shall be in sufficient detail to properly reflect, in good
scientific manner, all significant work done and results of studies and trials undertaken and further shall be at a level of detail appropriate for patent and regulatory purposes. If reasonably necessary for a Party to perform its work under this
Agreement or to exercise its rights under this Agreement, such Party may request that, and the other Party shall provide within a reasonable timeframe, such information and data regarding its activities hereunder as is reasonably available and
reasonably related its activities under this Agreement; provided that neither Party shall be required to generate additional data or prepare additional reports to comply with the foregoing obligation. All such reports, information and data provided
shall be subject to the provisions of Article 9.

 7.10    Lilly’s Right of First Negotiation. Terns, on behalf
of itself and its Affiliates, hereby agrees that it shall not enter into a term sheet or commence agreement negotiations with a Third Party partner to Commercialize a Covered Product in any country in the Territory as Terns’ sublicensee or
assignee (the “Covered Product Opportunity”) without first providing written notice thereof and offering the exclusive right and option of first negotiation with respect to such Covered Product Opportunity (the “Lilly ROFN
Option”). For clarity, the foregoing shall not prevent Terns from freely engaging in preliminary discussions with any Third Party about such rights that customarily take place prior to term sheet or agreement negotiations, nor require
Terns, as a result of engaging such preliminary discussions, to provide the above written notice triggering Lilly ROFN Option. Lilly may exercises such Lilly ROFN Option by providing Terns with written notice of the same within [***] of its receipt
of Terns’ written notice described above. Upon Lilly’s timely exercises of the Lilly ROFN Option in accordance with the preceding sentence, then the Parties shall negotiate in good faith and on an exclusive basis for up to an additional
[***] from such exercise (the “Negotiation Period”) regarding the terms pursuant to which Lilly would obtain the rights in such Covered Product Opportunity. If Lilly fails to deliver notice of exercise of the Lilly ROFN Option to
Terns prior to expiration of the [***] period described above, then, effective upon such expiration, Lilly shall be deemed to have irrevocably waived the Lilly ROFN Option with respect to solely the Covered Product Opportunity at issue. If Lilly is
deemed to have irrevocably waived the Lilly ROFN Option pursuant to the preceding sentence, or if Lilly delivers written notice of exercise of the Lilly ROFN Option with in the notice period prescribed above but the Parties fail to enter into a
definitive agreement regarding the Covered Product Opportunity at issue (a “Definitive Agreement”) prior to expiration of the Negotiation Period, then, in either case, effective upon such expiration (of the exercise notice period or
the Negotiation Period, as applicable), (a) the Lilly ROFN Option shall terminate and be of no further force or effect with respect to the Covered Product Opportunity at issue and (b) Terns shall be free to terminate negotiations with Lilly and
to offer to grant, license, sell or otherwise convey, and to grant, license, sell or otherwise convey, to Third Parties solely the Covered Product Opportunity at issue. For clarity, neither Party shall have any obligation to enter into a Definitive
Agreement.

Commercialize, Covered Products in the Field in the Territory, including the right to grant sublicenses at any tier (subject to Article 3.4).

country-by-country and Covered Product-by-Covered Product basis, following the Regulatory
Approval of a Covered Product in the Subject Launch Market and if Terns (or Terns’ Sublicensee) decides in good faith to Commercialize such Covered Product in the Subject Launch Market, Terns will provide written notice to Lilly of such
decision, and upon Lilly’s written request, Lilly shall have a co-promotion option for the Subject Launch Market, exercisable separately for each such Covered Product and

each such country in the Subject Launch Market, to assume responsibility for a certain percentage of the detailing for such Covered Product in the Subject Launch Market to be further negotiated
and agreed by the Parties. Each such option can be exercised by written notification to Terns within at [***] of the date of Terns’ notice of its decision. Upon exercise of such option for such Covered Product, the Parties shall negotiate in
good faith on terms for such co-promotion for such Covered Product for [***] days of Lilly’s notice exercising such option (the “Co- Promotion Option Period”);
provided that, if the Parties are not able to reach an agreement with respect to such co-promotion for such Covered Product within the aforementioned [***] period, Terns will have no further obligation to
Lilly with respect to the co-promotion of such Covered Product. Before and during the Co-Promotion Option Period, Terns will not enter into definitive agreements with a
Third Party providing such Third Party rights to co-promote such Covered Product.

has been identified in writing by such Party as a trade secret, in which case, the obligation contained in this Article 9.1 with respect to such Confidential Information shall be perpetual, the Party receiving the Confidential Information of the
other Party (such receiving Party, the “Receiving Party”) shall keep confidential and not publish, make available or otherwise disclose any Confidential Information to any Third Party, without the express prior written
consent of the Party that disclosed such Confidential Information (the “Disclosing Party”); provided however, the Receiving Party may disclose the Confidential Information to those of its Affiliates, officers, directors,
employees, agents, consultants and/or independent contractors (including Sublicensees) of such Receiving Party who need to know the Confidential Information in connection with this Agreement and are bound by confidentiality obligations with respect
to such Confidential Information. The Receiving Party shall exercise at a minimum the same degree of care it would exercise to protect its own confidential information (and in no event less than a reasonable standard of care) to keep confidential
the Confidential Information. The Receiving Party shall use the Confidential Information solely in connection with the purposes of this Agreement. 

(b)    It shall not be considered a breach of this Agreement if the Receiving Party discloses Confidential Information in
order to comply with a lawfully issued court or governmental order or with a requirement of Applicable Law or the rules of any internationally recognized stock exchange; provided that: (i) the Receiving Party gives prompt written notice of such
disclosure requirement to the Disclosing Party and cooperates with Disclosing Party’s efforts to oppose such disclosure or obtain a protective order for such Confidential Information, and (ii) if such disclosure requirement is not quashed
or a protective order is not obtained, the Receiving Party shall only disclose those portions of the Confidential Information that it is legally required to disclose and shall make a reasonable effort to obtain confidential treatment for the
disclosed Confidential Information. Notwithstanding the foregoing provisions of Article 9.l(a), either Party may disclose Confidential Information of the other Party if such Party is required to make such disclosure by

circumstances that reasonably protect the confidentiality thereof, or to the extent necessary to comply with the terms of agreements with Third Parties, or to the extent required by Applicable Laws, including securities laws. Notwithstanding the
foregoing, the Parties must agree upon the initial press release(s) to announce the execution of this Agreement; thereafter, Lilly and Terns may each disclose to Third Parties the information contained in such press release(s) without the need for
further approval by the other. Furthermore, for purposes of clarity, notwithstanding anything to the contrary in this Agreement, either Party may disclose Confidential Information of the other Party if such Party is required to make such disclosure
by Applicable Laws, including, in response to rules or guidance of the United States Internal Revenue Service or other taxing authority, or in other legal processes, including by the rules or regulations of the United States Securities and Exchange

 12.2    Patent Filing, Prosecution and Maintenance. Terns shall
have sole responsibility and decision-making authority for all Patent Prosecution actions relating to (a) (i) the Lilly Patents set forth on Exhibit A and (ii) Patents contained in the Lilly Developed IP that are [***] the Covered
Compounds or Covered Products, and (b) the Patents contained in the Terns Developed IP that are [***] the Covered Compounds or Covered Products ((a) and (b), the “Terns Prosecuted Patents”), at Terns’ expense. Terns shall
establish an overall strategy for the Patent Prosecution of Terns Prosecuted Patents. The primary objective of each such strategy shall be to [***]. Terns shall keep Lilly informed of the status of Patent Prosecution actions taken in the Territory
with respect to Terns Prosecuted Patents, including regularly providing the informed entities with copies of all prospective patent applications and patent applications filed hereunder and other material submissions and correspondence with
government agencies concerning the Terns Prosecuted Patents, as applicable. When applicable, for material Patent Prosecution events, Terns shall consider the advice and suggestions of Lilly’s patent counsel before taking an action. 

12.3    Patent Oppositions. In consultation with the Parties’ patent departments, the Parties will mutually
decide whether and how to participate in Patent oppositions and undertake activities intended to invalidate Third Party Patents when necessary, at Terns expense. Each Party will keep the other Party informed and apprised of any such decisions and
activities. 
 12.4    Abandonment of Patent or Patent Prosecution. Terns may in its sole discretion elect to
discontinue Patent Prosecution in any country on a Patent-by-Patent as provided for under Article 12.2 above. Terns shall give prompt notice to Lilly if Terns declines

take over Patent Prosecution of such Patent, then Terns shall promptly deliver to Lilly copies of all necessary files related to such Patent with respect to which responsibility has been transferred and shall take all actions and execute all
documents reasonably necessary for Lilly to assume such responsibility and shall assign such Patents to Lilly. As of the date of such notice of Terns’ assignment or return to Lilly, Terns shall have no further liability to Lilly for such Patent

extensions; and

 [***] = [CONFIDENTIAL PORTION HAS
BEEN OMITTED BECAUSE IT (I) IS NOT MATERIAL AND (II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED] 

 (d)    act in good faith to coordinate its efforts under this Agreement
with the other Party to minimize or avoid interference with the Patent Prosecution of the other Party’s Patents to the Covered Product. 

12.6    Enforcement. 

(a)    Notice. Each Party shall promptly provide, but in no event later than [***], to the other with written
notice reasonably detailing any known or alleged infringement of any Patent or trademark owned or Controlled by either Party and subject to a license under this Agreement. 

(b)    Enforcement of Intellectual Property Rights. Terns shall have the first right (but shall not be obligated)
to bring and control an action to enforce Lilly Patents against any Third Party believed to be infringing such Patent or misappropriating or otherwise violating any Lilly Know-How in the Territory, at its
cost; provided, however, that Terns shall consult in advance with Lilly regarding such action. If Terns does not abate such violation of the Lilly Patent or Lilly Know-How by commencement of a lawsuit against
the Third Party if necessary, then Lilly shall have the second right (but shall not be obligated) to take all actions reasonably necessary to abate such violation, including commencement of a lawsuit against the Third Party if necessary, at its
cost. The primary objective of any patent enforcement action shall be [***]. All amounts recovered from enforcement of any such rights by either Party relating to the intellectual property licensed under this Agreement shall be first used to
reimburse each Party’s costs and expenses incurred in connection with such action, and any remainder of such recovery shall be [***]. 

(c)    Cooperation in Enforcement Proceedings. For any action by a Party pursuant to
sub-article (b) above, in the event that such Party is unable to initiate or prosecute such action solely in its own name, the other Party will join such action voluntarily and will execute all documents
necessary for such Party to initiate, prosecute and maintain such action. If either Terns or Lilly initiates an enforcement action pursuant to Article 12.6(b), then the other Party shall cooperate to the extent reasonably necessary and at the first
Party’s sole expense (except for the expenses of the non-controlling Party’s counsel, if any). Upon the reasonable request of the Party instituting any such action, such other Party shall join the
suit and can be represented in any such legal proceedings using counsel of its own choice. Each Party shall assert and not waive the joint defense privilege with respect to all communications between the Parties reasonably the subject thereof. 

12.7    Defense. 

(a)    Notice. Each Party shall notify the other in writing of any allegations it receives from a Third Party that
the Manufacture, production, use, Development, Commercialization or distribution of any Covered Product or any technology or intellectual property licensed by a Party under this Agreement infringes the intellectual property rights of such Third
Party. Such notice shall be provided promptly, but in no event after more than [***], following receipt of such allegations. Such written notice shall include a copy of any summons or complaint (or the equivalent thereof) received regarding the
foregoing. Each Party shall assert and not waive the joint defense privilege with respect to all communications between the Parties. 

  
 27 

  
 [***] = [CONFIDENTIAL PORTION HAS
BEEN OMITTED BECAUSE IT (I) IS NOT MATERIAL AND (II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED] 

 (b)    Conduct of Defense. In such event, the Parties shall agree
how best to mitigate or control the defense of any such legal proceeding, agree whether to enter into a joint defense agreement to, among other reasons, preserve the confidentiality of communications or cooperation between the Parties in relation to
such defense, and determine which Party is best suited to assume the primary responsibility for the conduct of the defense of any such claim at their expense. The other Party shall have the right, but not the obligation, to participate and be
separately represented in any such suit at its sole option and at its own expense. Each Party shall reasonably cooperate with the Party conducting the defense of the claim. If a Party or any of its Affiliates have been individually named as a
defendant in a legal proceeding relating to the alleged infringement of a Third Party’s Patents or other intellectual property right as a result of the Manufacture, production, use, Development, Commercialization or distribution of the Covered
Product, then that Party shall conduct the defense and the other Party shall be allowed to join in such action, at its own expense. 

(c)    Status; Settlement. The Parties shall keep each other informed of the status of and of their respective
activities regarding any infringement litigation initiated by a Third Party concerning a Party’s Manufacture, production, use, Development, Commercialization or distribution of the Covered Product or settlement thereof; provided, however, that
no settlement or consent judgment or other voluntary final disposition of a suit under this Article 12.7(c) may be undertaken by a Party without the consent of the other Party which consent shall not be unreasonably withheld or delayed. 

(d)    Limitations. Notwithstanding anything to the contrary in this Article 12.7, if a Party is an Indemnifying
Party with respect to any Losses stemming from a claim or action by a Third Party alleging infringement of a Third Party’s Patents or other intellectual property right as a result of the Manufacture, production, use, Development,
Commercialization or distribution of the Covered Product or any technology or intellectual property licensed by a Party under this Agreement, Article 11 shall supersede this Article 12.7 with respect to the defense and settlement of such action or
claim to the extent there are conflicts.

of treatment, if appropriate, and compliance with Applicable Laws. Upon early termination of this Agreement, the Parties shall cooperate to provide for an orderly cessation of any clinical trials. Each Party further agrees to take no action or

	14.	 DISPUTE RESOLUTION 

14.1    Disputes. The Parties recognize that disputes as to certain matters may from time to time arise which relate
to either Party’s rights or obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of such disputes in an expedient manner by mutual cooperation; however, should a dispute arise, the
Parties agree to follow the arbitration procedures set forth in Article 14.2. 
 14.2    Arbitration Procedures.
In the event of a dispute, that cannot be resolved through good faith negotiations as set forth above, the dispute shall be referred to and finally resolved by arbitration in the following manner: 

(a)    The dispute shall be settled by arbitration in New York, USA under the Rules of Arbitration of the International
Chamber of Commerce (the “Rules”) in force when the notice of arbitration is submitted in accordance with the Rules. There shall be [***] arbitrators appointed in the following manner: each Party shall nominate an arbitrator for
confirmation as provided in the Rules and following their confirmation, the third arbitrator shall be appointed by the International Court of Arbitration of the International Chamber of Commerce; provided, however, that such [***] arbitrator shall
have substantive expertise in the pharmaceutical industry. 
 (b)    The arbitral proceedings shall be conducted in
English. To the extent that the Rules are in conflict with the provisions of this Article 14.2, including the provisions concerning the appointment of the arbitrator, the provisions of this Article 14.2 shall prevail. 

(c)    Each Party to the arbitration shall cooperate with each other Party to the arbitration in making full disclosure of
and providing complete access to all information and documents requested by such other Party in connection with such arbitral proceedings, subject only to any confidentiality obligations binding on such Party. 

(d)    The award of the arbitral tribunal shall be final and binding upon the Parties a party thereto, and the prevailing
Party may apply to a court of competent jurisdiction for enforcement of such award. 
 (e)    Any Party that is a party
to the dispute shall be entitled to seek preliminary injunctive relief, if possible, from any court of competent jurisdiction pending the constitution of the arbitral tribunal. 

 

	15.	 MISCELLANEOUS. 

15.1    Force Majeure. Neither Party shall be held liable to the other Party nor be deemed to have defaulted under
or breached this Agreement for failure or delay in performing any obligation under this Agreement to the extent such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party including, but not limited
to, embargoes, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, or other acts of God, or acts, omissions or delays

 [***] = [CONFIDENTIAL PORTION HAS
BEEN OMITTED BECAUSE IT (I) IS NOT MATERIAL AND (II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED] 

 
in acting by any Governmental Authority. The affected Party shall notify the other Party of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake all
commercially reasonable efforts necessary to cure such force majeure circumstances. 
 15.2    Assignment or Change
of Control. 
 (a)    Except as otherwise set forth in this Agreement, this Agreement and its rights, privileges,
and obligations may not be assigned or otherwise transferred by either Party without the prior written consent of the other Party; provided that either Party may assign, without consent but with prior written notice, such Party’s rights and
obligations, in whole or in part, under this Agreement (i) in connection with a merger, consolidation, or sale of substantially all of the assigning Party’s assets related to this Agreement to an unrelated Third Party, (ii) in
connection with a Change of Control, or (iii) to an Affiliate of such Party (in which case the Affiliate to whom any rights or obligations have been assigned shall be considered a “Party” to this Agreement for purposes of such rights
and obligations); provided that in the case of an assignment of obligations by Terns to a Terns Affiliate, if such Terns Affiliate fails to perform such obligations, then Terns shall remain liable in all respects under this Agreement for such
obligations, notwithstanding the assignment to such Affiliate. For clarity, Article 15.2(a)(iii) includes the right for Terns to assign any rights or obligations under this Agreement to an Affiliate in Mainland China, and in case of such assignment,
such Affiliate would make payments required under this Agreement directly to Lilly. 
 (b)    For the purposes of this
Agreement, a “Change of Control” of a Party occurs upon (i) the closing of a sale of all or substantially all of the assets of such Party to a Third Party in one transaction or series of transactions, (ii) the closing of a
merger or other business combination or transaction that results in a Third Party owning, directly or indirectly, of more than fifty percent (50%) of the voting securities of such Party, or (iii) the closing of a transaction, following which a
Third Party acquires direct or indirect ability or power to direct or cause the direction of the management and policies of such Party or otherwise direct the affairs of such Party, whether through ownership of equity, voting securities, beneficial
interest, by contract, or otherwise, provided that for the purposes of this Agreement, a Change of Control shall not be deemed to have taken place if such Change of Control transaction involves a reorganization or similar transaction amongst the
direct or indirect shareholders or Affiliates of such Party, following which a shareholder or Affiliate of such Party emerges as the direct or indirect owner of more than fifty percent (50%) of the voting securities, or owning all or substantially
all the assets of the Party, or acquiring the direct or indirect ability or power to direct or cause the direction of the management and policies of such Party. Any assignee must assume in writing the obligations of the assigning Party to which it
is the assignee or successor. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective permitted successors and assigns. Any attempted assignment or transfer of this Agreement not in accordance with this
Article 15.2 shall be null and void. 
 15.3    Severability. If any one or more of the provisions contained in
this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the
invalidated provision(s) adversely affects the substantive rights of the Parties. The Parties shall in such an instance use their best efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable
provision(s) which, insofar as practical, implement the purposes of this Agreement.

transaction described in the Notice. Terns will have [***] following its receipt of the Notice (“Offer Period”) to exercise this right by providing written notice to Vintagence. Upon the expiration of the Offer Period without
Terns exercising this right, Vintagence will be free to execute the transaction under the terms described in the Notice. If (a) Vintagence receives a bona fide offer to enter into a transaction for the Competing Product with different terms, or
(b) the transaction described in the Notice is not executed within [***] after the end of the Offer Period, Vintagence will be required to comply with terms of this Section 5.2 again.

 6.3    Tax Withholding. If any payments required to be made by a
Party under this Agreement are or become subject to withholding taxes (including any value added tax) under Applicable Laws of any state, federal, provincial or foreign government, such Party shall be authorized to withhold such taxes as are
required under Applicable Law, pay such taxes to the appropriate Governmental Authority, deduct them from such payments, and remit the balance due to the other Party net of such taxes. The Party paying the taxes to the Governmental Authority shall
secure and deliver to the other Party an official receipt for taxes paid. In the event that the governing tax authority retroactively determines that a payment pursuant to this Agreement should have been subject to withholding (or to additional
withholding) for taxes, and a Party (the “Withholding Party”) remits such taxes to the tax authority, the Withholding Party will invoice the other Party for such amount, and the other Party will pay such amount within [***] of the
receipt of such invoice. 
 6.4    Tax Administration. The Parties agree to fully cooperate with each
other to enable each Party to more accurately determine its own tax liability and to minimize such liability to the extent legally permissible and administratively reasonable. Each Party shall provide and make available to the other Party any
exemption certificates, resale certificates, or other required tax forms reasonably requested by the other Party to support the provisions of this Agreement.

“Receiving Party”) shall keep confidential and not publish, make available or otherwise disclose any Confidential Information to any Third Party, without the express prior written consent of the Party that disclosed such
Confidential Information (the “Disclosing Party”); provided however, the Receiving Party may disclose the Confidential Information to those of its Affiliates, officers, directors, employees, agents, consultants and/or
independent contractors (including Licensees) of such Receiving Party who has to know the Confidential Information in connection with this Agreement and is subject confidentiality and non-use obligations,
which shall be as same as the obligation of Receiving Party, with respect to such Confidential Information. The Receiving Party shall exercise at a minimum the same degree of care it would exercise to protect its own confidential information (and in
no event less than a reasonable standard of care) to keep confidential the Confidential Information. The Receiving Party shall use the Confidential Information solely in connection with the purposes of this Agreement. Notwithstanding the foregoing,
the Vintagence Know-How shall be deemed as Confidential Information, and Vintagence shall not (without Terns’ prior written consent in each case) disclose to any Third Party any Vintagence Know-How or use such Vintagence Know-How other than to perform its obligations under this Agreement for the benefit of Terns. 

(b)    It shall not be considered a breach of this Agreement if the Receiving Party discloses Confidential
Information in order to comply with a lawfully issued court or with a requirement of Applicable Law; provided that: (i) the Receiving Party gives prompt written notice of such disclosure requirement to the Disclosing Party and cooperates with
Disclosing Party’s efforts to oppose such disclosure or obtain a protective order for such Confidential Information, and (ii) if such disclosure requirement is not quashed or a protective order is not obtained, the Receiving Party shall
only disclose those portions of the Confidential Information that it is legally required to disclose and shall make a reasonable effort to obtain confidential treatment for the disclosed Confidential Information. Notwithstanding the foregoing
provisions of Article 8.1(a), either Party may disclose Confidential Information of the other Party if such Party is required to make such disclosure by Applicable Laws, in response to rules or guidance of the United States Internal Revenue
Service or other taxing authority, or in other legal processes, including by the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States or of any stock
exchange or other securities trading institution and shall disclose only such Confidential Information of such other Party as is required to be disclosed. 

8.2    Publicity; Use of Names. 

(a)    Confidential Terms. Each of the Parties agrees not to disclose to any Third Party the terms and
conditions of this Agreement without the prior approval of the other Party, except to advisors (including consultants, financial advisors, attorneys and accountants), potential and existing investors and acquirers on a need to know basis, in each
case under circumstances that reasonably protect the confidentiality thereof, or to the extent necessary to comply with the terms of agreements with Third Parties, or to the extent required by Applicable Laws, including securities laws.
Notwithstanding the foregoing, Terns may record in any national or supranational jurisdiction in the Territory any assignments for patent rights provided hereunder and register this Agreement pursuant to Applicable Law, and the Parties must agree
upon the initial press release(s) 

  
 10 

 
to announce the execution of this Agreement; thereafter, Vintagence and Terns may each disclose to Third Parties the information contained in such press release(s) without the need for further
approval by the other. Furthermore, for purposes of clarity, notwithstanding anything to the contrary in this Agreement, either Party may disclose Confidential Information of the other Party if such Party is required to make such disclosure by
Applicable Laws, including, in response to rules or guidance of the United States Internal Revenue Service or other taxing authority, or in other legal processes, including by the rules or regulations of the United States Securities and Exchange
Commission or similar regulatory agency in a country other than the United States or of any stock exchange or other securities trading institution and shall disclose only such Confidential Information of such other Party as is required to be
disclosed.

 13.    DISPUTE RESOLUTION. 

13.1    Disputes. The Parties recognize that disputes as to certain matters may from time to time arise which
relate to either Party’s rights or obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of such disputes in an expedient manner by mutual cooperation; however, should a dispute arise,
the Parties agree to follow the arbitration procedures set forth in Article 13.2. 
 13.2    Arbitration
Procedures. In the event of a dispute, that cannot be resolved through good faith negotiations as set forth above, the dispute shall be referred to and finally resolved by arbitration in the following manner:

the pharmaceutical industry. 
 (b)    The arbitral proceedings shall be conducted in English. To the extent that
the Rules are in conflict with the provisions of this Article 13.2, including the provisions concerning the appointment of the arbitrator, the provisions of this Article 13.2 shall prevail. 

(c)    Each Party to the arbitration shall cooperate with each other Party to the arbitration in making full
disclosure of and providing complete access to all information and documents requested by such other Party in connection with such arbitral proceedings, subject only to any confidentiality obligations binding on such Party.

14.5    Waiver. The waiver by either Party of any right hereunder, or the failure of the other Party to
