 7.3    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 7.1: 

(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

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

(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.

Parties under Article 7.3(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

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













 
Calendar Quarter, then, during the Royalty Term, Lilly’s royalty rates as set forth in Article 7.3 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 7.3 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 7.1 with respect to a Covered Product in a country be reduced by operation of any subsection of this Article 7.3 by more than an aggregate of [***] of what would otherwise be owed under Article 7.1 with respect to [***].

 7.4    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.

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













 7.5    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, [***]. 
 7.6    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 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. 
  

	8.	 LICENSES; EXCLUSIVITY. 



8.1    Exclusive License to Covered Product and Right to Sublicense. Subject to the terms and conditions of

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

8.2    China Commercialization Option. On a
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 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. 
 8.3    No Implied Licenses. Except as
explicitly set forth in this Agreement, neither Party grants any license, express or implied, under its intellectual property rights to the other Party.

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

(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

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

and/or export of the Covered Products (as such exist on the date of termination).

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. 
 15.4    Notices. All notices which are required or permitted
hereunder shall be in writing and sufficient if delivered personally, sent by nationally-recognized overnight courier or sent by registered or certified mail, postage prepaid, return receipt requested, addressed as follows:

15.10    Waiver of Rule of Construction. Each Party has had the opportunity to consult with counsel in connection
