 ACCOUNTING AND
REPORTING 
 6.1    Royalty Reports. Within [***] after the end of each Calendar Quarter during the
Royalty Term, Hansoh shall furnish to CaspianTern a quarterly written report showing in reasonably specific detail (a) the calculation of Net Sales by Hansoh and its Affiliates during such Calendar Quarter; (b) the calculation of Net Sales
by Hansoh’s non-Affiliate Sublicensees, if any, during the Calendar Quarter immediately preceding such Calendar Quarter; (c) the calculation of the royalties, if any, that shall have accrued based
upon such Net Sales; (d) the withholding taxes, if any, required by law to be deducted with respect to such sales; and (e) the exchange rates, if any, used in determining the amount of Dollars (a “Royalty Report”).
With respect to sales of Licensed Products invoiced in Dollars, the gross sales, Net Sales and royalties payable shall be expressed in Dollars. With respect to (i) Net Sales invoiced in a currency other than Dollars and (ii) cash
consideration paid in a currency other than Dollars by Sublicensees hereunder, all such amounts shall be expressed both in the currency in which the distribution is invoiced and in the Dollar equivalent. The Dollar equivalent shall be calculated
using the average of the exchange rate (local currency per US$1) published in The Wall Street Journal, Western Edition, under the heading “Currency Trading” on the last business day of each month during the applicable Calendar Quarter, or
other newspaper agreed to by the Parties. 
 6.2    Audits. During the Royalty Term, upon the written

accounting firm to have access during normal business hours to such of the financial records of Hansoh as may be reasonably necessary to verify the accuracy of the payment reports hereunder for the [***] immediately prior to the date of such request

firms satisfies the requirements under this Section 6.2 and is acceptable to Hansoh. 
 6.2.1    If such
accounting firm concludes that additional amounts were owed during the audited period, Hansoh shall pay such additional amounts within [***] after the date CaspianTern delivers to Hansoh such accounting firm’s written report so concluding. The
fees charged by such accounting firm shall be paid by CaspianTern; provided, however, if the audit discloses that the royalties payable by Hansoh for such period are more than [***] of the royalties actually paid for such period, then Hansoh shall
pay the reasonable, in any case no more than [***], fees and expenses charged by such accounting firm. 

6.2.2    CaspianTern shall cause its accounting firm to retain all financial information subject to review under
this Section 6.2 in strict confidence; provided, however, that Hansoh shall have the right to require that such accounting firm, prior to conducting such audit, enter into an appropriate non-disclosure

treat all such financial information as Hansoh’s Confidential Information.

the licensed under Section 7.1.3; provided that CaspianTern’s Exploitation and sublicense of such Option Period Study Results shall in no event conflict with Section 3.1.1. Inventorship and authorship will be determined under the
applicable rules and precedents prevailing in the United States. For clarity, any Option Period Study Results solely or jointly owned by CaspianTern shall be included in the Licensed Technology. 

7.1.3    Other IP. Any and all Intellectual Property conceived, developed or acquired after the License
Effective Date and arising directly out of the activities under this Agreement which are necessary or useful for the Exploitation of a Licensed Compound or Licensed Product, (a) shall be owned by Hansoh or its Affiliates to the extent the same
was conceived, developed or acquired solely by or on behalf of Hansoh (the “Hansoh Development IP”), provided that [***]; further provided that CaspianTern’s Exploitation and sublicense of such Hansoh Development IP

faith negotiations with Hansoh regarding such license; thereafter the Parties shall have [***] (the “RFN Period”) to negotiate exclusively the terms of such license. If CaspianTern (i) gives notice that it does not wish
to pursue such license, (ii) fails to give a notice of its desire to negotiate such license within the [***] period, or (iii) the Parties fail to reach agreement on the terms of such license within the RFN Period, then CaspianTern’s
rights pursuant to this Section 7.1.4 will expire and Hansoh shall be free to enter into a transaction with any Third Party with respect to the applicable Hansoh Development IP, provided that if during the RFN Period CaspianTern submitted an
offer in writing, Hansoh can only enter into such transaction with a Third Party on terms and conditions no more favorable to such Third Party than those offered by CaspianTern. 

7.1.5    Rights of Joint Owners. Subject to the licenses and covenants in this Agreement, including Sections

exercises the Option, upon and after the Option Exercise for the rest of the Term. To the extent Terns Inc controls Prosecution of Licensed Patent Rights in the Territory, Terns Inc hereby transfers such control upon Hansoh’s exercise of the
Option, and shall cause the inventors named on such Licensed Patent Rights to provide reasonable assistance to Hansoh to Prosecute such Licensed Patent Rights in the Territory. The Prosecuting Party shall regularly provide the other Party with
copies of all material prosecution communications regarding any such Licensed Patent Rights in the Territory, and drafts of such material prosecution submissions prior to filing, in sufficient time to allow for review and comment by such other
Party, and the prosecuting Party will consider in good faith and will use reasonable efforts to arrive at joint decisions on response. In the event that the Prosecuting Party decides not to Prosecute and Maintain any such Licensed Patent Rights in

the Licensed Patent Rights or the infringement or misappropriation of Licensed Know-How by a Third Party, to the extent such infringement involves Exploitation in the Field during the Term. Any suspected
infringement of any of the Licensed Patent Rights in the Field in the Territory is referred to herein as a “Covered Infringement.” 

7.3.2    First Right to Take Action. If a suspected infringement or misappropriation does not involve a
Covered Infringement, CaspianTern may take, or refrain from taking, any action CaspianTern chooses, and Hansoh shall have no right to take any action with respect to such suspected infringement or misappropriation, nor to any recoveries with respect
thereto. CaspianTern will exert reasonable efforts to keep Hansoh informed of actions CaspianTern may take as described in the preceding sentence. If the suspected infringement involves a Covered Infringement, Hansoh shall, within [***] of the first
notice referred to in Section 7.3.1, inform CaspianTern whether or not Hansoh intends to institute suit against such Third Party with respect to such Covered Infringement. CaspianTern will not take any steps toward instituting suit against any
Third Party involving a Covered Infringement until Hansoh has informed CaspianTern of its intention pursuant to the previous sentence. 

7.3.3    Action by Hansoh. If Hansoh notifies CaspianTern that Hansoh intends to institute suit against a

reimbursement of Hansoh for the costs of such action, [***].

CaspianTern that it desires to institute suit against such Third Party with respect to a Covered Infringement, and CaspianTern notifies Hansoh within [***] after receipt of such notice that CaspianTern desires to institute suit jointly, the suit
shall be brought jointly in the names of both Parties and all costs thereof shall be borne equally. Recoveries, if any, whether by judgment, award, decree or settlement, shall, after the reimbursement of each of CaspianTern and Hansoh for its share
of the joint costs in such action, [***]. 
 7.3.5    Action by CaspianTern. If Hansoh notifies
CaspianTern that it does not intend to institute suit against such Third Party with respect to a Covered Infringement (or fails to give any notice in this respect or to actually bring a suit against the Third Party), CaspianTern may institute suit
on its own. CaspianTern shall bear all costs of, and shall exercise all control over, such suit. Recoveries, if any, whether by judgment, award, decree or settlement, shall belong solely to CaspianTern.

7.3.7    Cooperation. In any suit to enforce and/or defend the Licensed Patent Rights pursuant to this
Section 7.3, the Party not in control of such suit shall, at the request and expense of the controlling Party, reasonably cooperate and, to the extent possible, have its employees testify when requested and make available relevant records,

breach of this Agreement, including any covenants, representations or warranties herein by the Indemnitor, or the gross negligence or willful misconduct of the Indemnitor in the performance of its obligations under this Agreement, except in each
case to the extent arising from the gross negligence or willful misconduct of the Indemnitee or the breach of this Agreement by the Indemnitee. 

10.2.2    CaspianTern, as the Indemnitor, shall defend, indemnify, and hold Hansoh and its Affiliates and
Sublicensees (as the Indemnitee) harmless from all losses, liabilities, damages and expenses (including attorneys’ fees and costs) incurred as a result of any claim, demand, action or proceeding arising out of (a) the Exploitation of

or action in respect of which the Indemnitee intends to claim such indemnification, and the Indemnitor shall have the right to assume the defense thereof with counsel selected by the Indemnitor. The indemnity agreement in this Section 10.2
shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld unreasonably. The failure to deliver notice to
the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve the Indemnitor of any liability to the Indemnitee under this this Section 10.2. The Indemnitee
under this Section 10.2, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigation and defense of any action, claim or liability covered by this indemnification.

other Party materially breaches this Agreement and has not cured such breach to the reasonable satisfaction of the other Party within ninety (90) days after notice of such breach from the non-breaching
Party; provided, however, that if the alleged breaching Party disputes in good faith the existence or materiality of a breach specified in such notice of breach and such alleged breaching Party provides the other Party notice of such dispute within
thirty (30) days after receiving such notice, then the Party that gave the notice of breach shall not have the right to terminate this Agreement under this Section 11.2 unless and until it is determined in accordance with Section 12.3
that the alleged breaching Party has materially breached the Agreement as specified in the notice of breach, and then such breaching Party fails to cure such breach within ninety (90) days following such determination. It is understood and
agreed that during the pendency of such dispute, all of the terms and conditions of this Agreement shall remain in effect and the Parties shall continue to perform all of their respective obligations hereunder. 

11.2.2    CaspianTern shall notify Hansoh immediately if there is any proposed change to either the Intangible
Property License Agreement effective as of August 19, 2019 by and between Terns Inc and Terns or the Intangible Property License Agreement effective as of June 16, 2020 by and between Terns and CaspianTern that would affect the licenses
granted hereunder to Hansoh. If such proposed change is not acceptable to Hansoh, then that shall be grounds for termination by Hansoh under this Section 11.2. 

11.3    Termination for Insolvency. Each Party shall have the right to terminate this Agreement upon written
notice to the other Party if the other Party incurs an Insolvency Event; provided, however, in the case of any involuntary bankruptcy proceeding, such right to terminate shall only become effective if the Party that incurs the Insolvency
Event consents to the involuntary bankruptcy or if such proceeding is not dismissed or stayed [***] after the filing thereof. “Insolvency Event” means circumstances under which a Party (i) has a receiver or similar
officer appointed over all or a material part of its assets or business; (ii) passes a resolution for winding-up of all or a material part of its assets or business (other than a winding-up for the purpose of, or in connection with, any solvent amalgamation or reconstruction) or a court enters an order to that effect; (iii) has entered against it an order for relief recognizing it as a
debtor under any insolvency or bankruptcy laws (or any equivalent order in any jurisdiction); or (iv) enters into any composition or arrangement with its creditors with respect to all or a material part of its assets or business (other than
relating to a solvent restructuring). All rights and licenses granted under or pursuant to this Agreement by Hansoh or CaspianTern or their Affiliates are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S.
Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that the Parties and their respective Affiliates, Sublicensees and Third Party sublicensees, as
licensees of such rights under this Agreement, will retain and may fully exercise all of their rights and elections under the U.S. Bankruptcy Code and any foreign counterparts thereto.

Agreement within [***] following a Change of Control of Terns or CaspianTern. If Hansoh wishes to exercise its termination right pursuant to this Section 11.5, Hansoh shall deliver written notice to Terns or CaspianTern, as the case may be,
informing Terns or CaspianTern of such election (such notice, the “Change of Control Termination Notice”) within [***] following such Change of Control, and the Parties shall take such actions as are required by Section 11.6.9. Such
termination shall be effective upon the execution of the Assignment Agreement pursuant to Section 11.6.9. Notwithstanding the foregoing, Hansoh shall not have the right to terminate this Agreement if the Third Party deemed to acquired control

licenses granted to Hansoh in Section 3.1 shall terminate solely with respect to the Licensed Compound(s), Licensed Product(s) and Region(s) in which the termination becomes effective; provided, however, that Hansoh and other Selling Parties,
as applicable, shall be permitted to distribute and sell all Licensed Products that were in inventory or in production on an effective termination date for a period of [***] following the effective termination date, in accordance with the terms of
this Agreement. In the event of a Termination for Breach by CaspianTern without cure, all licenses and rights granted by CaspianTern to Hansoh under this Agreement shall survive with all Milestone Payments and Royalty Payments obligations payable by
Hansoh to CaspianTern reduced by [***]. In the event that this Agreement is terminated in its entirety, CaspianTern shall have the right, but not the obligation, to purchase any and all of the inventory of Licensed Products held by Hansoh or its
Affiliates as of the date of termination, at a price agreed by the Parties. 
 11.6.3    Termination of this
Agreement shall be construed as a termination of all Sublicenses hereunder. 
 11.6.4    CaspianTern shall have
the right (including a reversion of all rights previously licensed to Hansoh hereunder for which the relevant licenses have terminated) to Exploit Licensed Products itself or with or through an Affiliate or one or more Third Parties in the Field in
the Territory, and shall have the right, without obligation to Hansoh, to take any such actions in connection with such activities as CaspianTern (or its designee), at its discretion, deems appropriate.

 Terns Pharmaceuticals and Hansoh Pharma Announce Collaboration and License Agreement for TRN-000632 in Greater China 
 -TRN-000632 is a potent
allosteric inhibitor of BCR-ABL in development for the treatment of CML- 
 - Terns is
eligible to receive an upfront fee and milestone payments of up to $68 million plus royalties on future product sales- 

-Preclinical and clinical studies evaluating TRN-000632 to be conducted in the partnership- 

FOSTER CITY, CA, and SHANGHAI, July [ ], 2020 – Terns Pharmaceuticals, Inc., a global biopharmaceutical company focused on discovering and developing
innovative therapies to treat liver disease and cancer, and Hansoh Pharmaceutical Group Company Limited (“Hansoh Pharma”; 3692:HK), a leading biopharmaceutical company in Asia, today announced a collaboration and license agreement for the
development and commercialization of TRN-000632, an investigational small molecule allosteric inhibitor of BCR-ABL for the treatment of chronic myeloid leukemia (CML),
in Greater China. 
 Under the terms of the agreement, Terns will receive an upfront payment and will be eligible to receive development, regulatory and
commercial milestones of up to $68 million, as well as royalties from future product sales. Hansoh will receive the exclusive rights to develop and commercialize TRN-000632 in Greater China. Terns retains
the right to develop and commercialize TRN-000632 in all other global markets. 
 “This collaboration was a
natural fit for TRN-000632, bringing together Hansoh’s experience as an established leader in CML treatment in China with Terns’ deep expertise in novel drug discovery,” said Martijn Fenaux,
Ph.D., Head of Research at Terns. “While tyrosine kinase inhibitors (TKIs) have been life-changing for many patients with CML, for many, tolerability and resistance issues remain a barrier to better outcomes. Because TRN-000632 binds an allosteric pocket unique to the mutant BCR-ABL, it is highly selective to a target that is distinct from that of currently available BCR-ABL TKIs, leading to an enhanced efficacy and overcoming difficult-to-treat acquired resistance. We look forward to the partnership
with Hansoh and their support of the research and development efforts for TRN-000632.” 
 “We are excited
to announce this partnership with Terns to rapidly deliver a valuable new therapy to patients in China, where CML incidence is a growing burden and resistance issues are a barrier to enduring efficacy for a significant number of patients,” said
Rudi Bao, M.D. Ph.D., SVP of Hansoh R&D. “We look forward to working with Terns and to advancing the development of the program as rapidly as possible.”
