basis, by Hanmi, its Affiliates and Sublicensees in the Territory in the Field based on the Net Sales tiers and royalty rates as set forth in the table below [***], subject to the reductions and offsets as may be applicable as set forth below in
this Section. 
  

			
	 Base Royalty Rate
	  	Annual Net Sales
(Determined Separately for Each Product)

	  	[***]

 (c)    Royalty Term. Royalties payable by Hanmi to RAPT under this
Section 8.4 (Royalty Payment to RAPT) shall be paid on a Product-by-Product and
country-by-country basis for a 

  
 - 27 - 

 
period commencing with the First Commercial Sale of such Product and until the later of: (a) the date of expiration of the
last-to-expire Valid Claim within the RAPT Patent Rights or Joint Patents, in each case Covering the
composition-of-matter of the Compound within such Product, or method-of-use of such
Product within the Territory, excluding, for the avoidance of doubt, any Hanmi Patents or any Joint Patents that claim formulations of the Product; (b) expiration of regulatory or data exclusivity (or data protection) granted by a Governmental
Authority that prevents a Third Party from obtaining an approval to sell a Generic Product; or (c) the date of expiration of five (5) years commencing with the First Commercial Sale of Product in that country (such period being the
“Royalty Term” for such Product and country). For clarity, Hanmi shall not owe royalties to RAPT under this Agreement on Product sold in a country after expiration of the Royalty Term for such Product in such country. Upon the
expiration of the Royalty Term with respect to a Product in such country, Hanmi shall have a [***] license under Section 7.1 (License to Hanmi) for the making, using, selling, offering for sale and importing of such Product in the Field in such
country. 
 (d)    Royalty Step-Down. On a
Product-by- Product and country-by-country basis, if such Product is not Covered by a
Valid Claim in such country during the Royalty Term, then the royalties payable with respect to such Licensed Product pursuant to Section 8.4(b) (Royalty on Products) in such country will be reduced by [***], which remaining royalty reflects
the value of the RAPT Know-How. 
 (e)    Third Party Payments. 

(i)    RAPT shall bear all Third Party license payments, milestones, royalties and other payments owed with respect to a
Compound and/or Product (including payments with respect to methods of making, using, selling, and/or identifying such Compound and Products) involving intellectual property (including Patents) that is licensed or otherwise acquired by RAPT, in its
sole discretion, as of the Effective Date or thereafter during the Term, it being understood and agreed that such Third Party payments, regardless of its nature, shall not have any impact of increasing the amount of any milestone payments or
royalties payable by Hanmi. 
 (ii)    Subject to Section 9.7 (Third Party Rights), each Party shall promptly
disclose detailed information pertaining to any Third Party Technology (as defined in Section 9.7(a)), directly to the other Party or through the JSC, as soon as practicable after the date a Party first became aware of such Third Party
Technology. 
 (iii)    Subject to the application of Section 9.7 (Third Party Rights), if (a) Hanmi obtains
a license to use the Third Party Technology in accordance with Section 9.7(a), or (b) if Hanmi[***] to obtain a license from any Third Party under any Patent in order to Develop, manufacture or Commercialize any Compound or Product in any
country in the Territory and proceeds with obtaining such license from the Third Party, Hanmi’s royalty obligations set forth above shall be reduced by an amount equal to [***] of the royalties paid by Hanmi to such Third Party on account of
such license on sales of such Compound or Product in the Field in the Territory; provided, however, that [***]. 

(f)    Generic Competition. During the portion of the applicable Royalty Term in a particular country within the
Territory where there are one or more products being sold in the Field in such country that are Generic Products with respect to the Product, then the royalty rate used to calculate the royalty payable by Hanmi on Net Sales of the Product in such
country shall be reduced as a percentage of one or more Generic Products’ market share in such country, as described below [***]. The data source for calculation would be IMS Midas (or an equivalent source available at the time). Upon a
Regulatory Filing for a first Generic Product, the JSC shall prepare a standard report (a “Generic Product Tracking Report”) that would track Net Sales of Product(s) and estimated Net Sales (i.e., applying estimated
deductions from gross sales) of Generic Product(s) on a country by country basis in the Territory on a Calendar Quarterly basis. The sales volumes for all Products and Generic Products would be included in this calculation. 

  
 - 28 - 

 [***] 

In the event one or more Generic Products achieve a market share of at least [***] of Net Sales in the Field in a country within the Territory, the Royalty
Term shall expire in such country. 
 8.5    Royalty Payments and Reports. All amounts payable to RAPT
pursuant to Section 8.4 (Royalty Payments to RAPT) shall be paid in Dollars within [***] after the end of the Calendar Quarter in which the applicable Net Sales were recorded. Each payment of royalties shall be accompanied by a royalty report
providing a statement, on a Product-by-Product and country-by-country basis, of:
(a) the amount of Net Sales of Products in the Territory during the applicable Calendar Quarter, (b) a calculation of the amount of royalty payment due in Dollars on such Net Sales for such Calendar Quarter, including the exchange rates
used and any applicable royalty rate reductions and (c) the amount of withholding taxes, if any, required by Applicable Law to be deducted with respect to such royalties. 

8.6    Payment Method. All payments due under this Agreement to RAPT shall be made by bank wire transfer in
immediately available funds to an account designated by RAPT. All payments and invoices hereunder shall be made in Dollars by Hanmi. 

8.7    Taxes. RAPT will pay any and all taxes levied on account of all payments it receives under
this Agreement. If laws or regulations require that taxes be withheld with respect to any royalty payments by Hanmi to RAPT under this Agreement, Hanmi will: (i) deduct those taxes from the remittable payment to RAPT, (ii) pay the taxes to
the proper taxing authority, and (iii) send evidence of the obligation together with proof of tax payment to RAPT on a timely basis following that tax payment. Each Party agrees to cooperate with the other Party in claiming refunds or
exemptions from such deductions or withholdings under any relevant agreement or treaty which is in effect. The Parties shall discuss applicable mechanisms for minimizing such withholding requirements and taxes to the extent possible in compliance
with Applicable Law. In addition, the Parties shall cooperate in accordance with Applicable Law to minimize indirect taxes (such as value added tax, sales tax, consumption tax and other similar taxes) in connection with this Agreement. 

8.8    Royalty on Sublicensee Sales. Hanmi shall have the responsibility to account for and report
sales of any Product by a Sublicensee on the same basis as if such sales were Net Sales by Hanmi. Hanmi shall pay to RAPT such Sublicensee amounts when due under this Agreement. 

8.9    Foreign Exchange. Conversion of sales recorded in local currencies to Dollars shall be
performed in a manner consistent with GAAP and Hanmi’s normal practices used to prepare its audited financial statements for internal and external reporting purposes. 

  
 - 29 - 

 8.10    Late Payment. If RAPT does not receive payment of
any sum due to it under this Agreement on or before the due date therefor, simple interest shall thereafter accrue on the sum due to RAPT from the due date until the date of payment at a per-annum rate of
[***] above the prime rate as reported in The Wall Street Journal, Eastern Edition or the maximum rate allowable by Applicable Law, whichever is less. 

8.11    Records. Hanmi shall keep, and shall cause its Affiliates and Sublicensees to keep, complete,
true and accurate books of accounts and records, including gross sales and any deductions thereto in connection with calculation of Net Sales, sufficient to determine and establish the amounts payable incurred under this Agreement, and compliance
with the other terms and conditions of this Agreement. Such books and records shall be kept reasonably accessible and shall be made available for inspection for a [***] period in accordance with Section 8.12 (Inspection of Hanmi Records) below.

 8.12    Inspection of Hanmi Records. Upon reasonable prior notice of not less than [***], Hanmi shall
permit an independent internationally recognized certified public accounting firm (subject to obligations of confidentiality to Hanmi), appointed by RAPT and accepted by Hanmi (such acceptance not unreasonably withheld, conditioned or delayed), to
inspect the audited financial records of Hanmi to the extent relating to payments and payment obligations to RAPT; provided that such inspection shall not occur more often than once per Calendar Year. If a material error is discovered as part
of such inspection, RAPT shall have the right to conduct a detailed inspection during the subsequent Calendar Year. Any inspection conducted under this Section 8.11 (Inspection of Hanmi Records) shall be at the expense of RAPT; provided
that, if such inspection determines that Hanmi underpaid RAPT by [***] or more during any Calendar Quarter, then Hanmi shall, within [***] of receiving an invoice and reasonable supporting documentation, reimburse RAPT for all of its payments to
Third Parties incurred in connection with such inspection. Any underpayment shall be paid by Hanmi to RAPT within [***] with interest on the underpayment from the date such payment was originally due in accordance with Section 8.10 (Late
Payment), and any overpayment shall be credited against future amounts due by Hanmi to RAPT. Any and all information generated during inspection shall be Confidential Information under Article 12 (Confidentiality) of this Agreement. 

8.13    Inventor Compensation. RAPT shall be responsible for and shall bear all costs associated with any
Inventor Compensation (defined below) for any employees of RAPT or any of its Affiliates (and/or of any Third Party contractors of RAPT or any of its Affiliates), whether employed at any time prior to the Effective Date or during the Term of the
Agreement. In addition, as between the Parties, RAPT shall be responsible for and shall bear all costs associated with any Inventor Compensation for any other developers or inventors of the RAPT Technology developed or invented as of the Effective
Date. “Inventor Compensation” means any compensation that is or may in the future become payable to inventors of RAPT Patent Rights or creators of RAPT Know-How or RAPT Materials for or based
upon the use and/or exploitation of the RAPT Technology, Compound and/or Products, including the use and commercial exploitation of RAPT Technology Compound and/or Products pursuant to this Agreement. 

9. PATENT PROSECUTION AND ENFORCEMENT 

9.1    Ownership of Information and Inventions. 

(a)    (i) Any and all improvements or inventions made or developed with respect to Compounds and/or Products, including
but not limited to, methods and materials used in the synthesis of Compound (including starting materials and intermediates for the synthesis of Compound) or the formulation of Product (the “Inventions”) conceived or reduced to
practice in the course of conducting activities under this Agreement and invented solely by or on behalf of RAPT and/or its Affiliates or Sublicensees and/or their respective employees, agents or independent contractors (and Patents that claim such
Inventions) will be owned solely by RAPT (collectively, “RAPT-Owned Inventions”), (ii) any and all Inventions conceived or reduced to practice in the course of conducting activities under this Agreement

  
 - 30 - 

 
and invented solely by Hanmi and/or its Affiliates or Sublicensees and/or their respective employees, agents or independent contractors, regardless of whether on behalf of RAPT and/or Hanmi,
(collectively, “Hanmi-Owned Inventions”) and Patents that solely claim or disclose the Hanmi-Owned Inventions, (“Hanmi Patents”) will be owned solely by Hanmi, and (iii) any and all Inventions conceived or
reduced to practice in the course of conducting activities under this Agreement and invented jointly by or on behalf of RAPT and Hanmi and/or their respective Affiliates, Sublicensees, and/or their respective employees, agents or independent
contractors (collectively, “Joint Inventions”) and Patents that claim or disclose the Joint Inventions (“Joint Patents”) will be jointly owned by the Parties, with each Party owning an undivided one-half interest in, to and under all Joint Inventions and Joint Patents. Subject to and without limiting the licenses granted under this Agreement and the other terms and conditions of this Agreement, Hanmi and
RAPT shall not otherwise have an obligation to account to the other Party, or obtain the consent of the other Party, with respect to the exploitation (directly or through licensees or other Third Parties) of any Joint Inventions or Joint Patents,
and Hanmi and RAPT hereby waive any right either may have under the laws of any jurisdiction to require such an accounting or consent. Notwithstanding anything in this Agreement to the contrary, Hanmi shall not file any patent application disclosing
or claiming any manufacturing process for the Compound, including other physical forms or its drug product. 

(b)    Each Party shall promptly disclose to the other Party all Inventions developed solely by such Party’s and its
Affiliates’, its Sublicensees’ and Third Party subcontractors’ employees, agents or independent contractors. For avoidance of doubt, any RAPT-Owned Inventions and RAPT’s interest in Joint Patents shall be deemed to be part of the
RAPT Technology and covered by the license under Section 7.1 (License to Hanmi). Subject to a Party’s obligations under applicable terms of this Agreement (e.g., licenses granted hereunder, confidentiality obligations, etc.) with respect
to same, any Information generated during or resulting from a Party’s activities under this Agreement (except to the extent containing Information first provided by the other Party) may be used by such Party for the purpose of researching (in
accordance with Article 3 (Research Program) and Developing Compound and Products under the terms set forth herein. 

9.2    Prosecution of RAPT Patents. 

(a)    RAPT will have the first right, but not the obligation, to draft, file, prosecute and maintain (including any
oppositions, interferences, reissue proceedings, reexaminations and post-grant proceedings) in all jurisdictions in the Territory the RAPT Patents (such activities with respect to Patents being the “Prosecution”, with the term
“Prosecute” having the corresponding meaning). For the purpose of this Agreement, the Party that is responsible for Prosecuting a particular Patent is referred to as the “Prosecuting Party” and such Prosecution
shall be handled by the outside counsel selected by the Prosecuting Party (the “Patent Firm”). Subject to Section 9.2(b) and (c), RAPT shall bear the Patent Prosecution Costs for the RAPT Patents, and shall have lead
responsibility and decision-making control for such Prosecution of the RAPT Patents. For clarity, each Party will bear its own internal costs (i.e., those costs that are not Patent Prosecution Costs) with respect to its Prosecution activities
for the RAPT Patents. 
 (b)    In the event that RAPT elects not to exercise its right to Prosecute in any country in
the Territory any RAPT Patent that claims the composition of the Compound or Product or any method of use within the Field of the Compound or the Product, RAPT will give Hanmi [***] notice [***] before any relevant deadline and provide to Hanmi
information it reasonably requests relating to the RAPT Patent. Hanmi will then have the right to assume responsibility, using patent counsel of its choice, for the Prosecution of such RAPT Patent in the Territory. If Hanmi assumes responsibility
for the Prosecution for any such RAPT Patents as set forth above, then the Patent Prosecution Costs incurred by Hanmi in the course of such Prosecution will thereafter be borne by Hanmi. 

(c)    The Parties will cooperate in such Prosecution of the RAPT Patents in all respects. Upon the request of the
Prosecuting Party, the other Party will provide the Prosecuting Party all reasonable assistance and cooperation in such Prosecution efforts, including providing any necessary powers of attorney and executing any other required documents or
instruments for such Prosecution, provided that 

  
 - 31 - 

 
[***]. The Prosecuting Party will, to the extent requested by the other Party, provide the other Party with copies of any material documents the Prosecuting Party receives or prepares in
connection with such Prosecution and will inform the other Party of the progress of it. Before filing in connection with such Prosecution any material document with a patent office, the Prosecuting Party will, upon the request of the other Party,
provide a copy of the document to the other Party sufficiently in advance to enable the other Party to comment on it, and the Prosecuting Party will give due consideration to such comments to the extent timely received. 

(d)    Patent Term Adjustments or Extensions. The Parties will confer regarding the desirability of seeking in any
country of the Territory of any patent term adjustment, patent term extension, supplemental patent protection or related extension of rights with respect to the RAPT Patents. RAPT shall have the sole right, but not the obligation, to apply for any
such adjustment, extension or protection. Notwithstanding the foregoing, upon Hanmi’s reasonable request, RAPT shall continue to apply for extension of patent terms and shall cooperate in good-faith with Hanmi for any adjustment and protection
of such patent terms within the Territory. Neither Party will proceed with such an extension until the Parties have consulted with one another and agreed to a strategy therefor, provided that in the case where the Parties are unable to reach
consensus, RAPT will have the final decision-making authority with respect to such decision; provided, further, that such decision will be made in accordance with Applicable Law so as to maximize
marketing exclusivity for the Product in the Field. Each Party will cooperate fully with and provide all reasonable assistance to the other Party and use all Commercially Reasonable Efforts consistent with its obligations under Applicable Law
(including any applicable consent order or decree) in connection with obtaining any such adjustments or extensions for the RAPT Patents consistent with such strategy. To the extent reasonably and legally required in order to obtain any such
adjustment or extension in a particular country, each Party will make available to the other a copy of the necessary documentation to enable such other Party to use the same for the purpose of obtaining the adjustment or extension in such country.

 9.3    Data Exclusivity (or Data Protection). As applicable, Hanmi will have the sole right and
authority for securing, maintaining and enforcing exclusivity (or protection) rights that may be available under Applicable Law in a country in the Territory for a Product, such as any data, market, pediatric, orphan drug or other regulatory
exclusivity (or protection) periods. RAPT will cooperate with and provide all reasonable assistance to Hanmi and use Commercially Reasonable Efforts consistent with its obligations under Applicable Law (including any applicable consent order or
decree) for Hanmi to seek, maintain and enforce all data exclusivity (or data protection) periods available for the Products in the Field in the Territory. 

9.4    Prosecution of Other Patents 

(a)    Joint Patents. Hanmi will have the first right, but not the obligation, to Prosecute in all countries within
the Territory all Joint Patents and RAPT will have the first right, but not the obligation, to Prosecute in all countries outside the Territory all Joint Patents. Prosecution of the Joint Patents within the Territory shall be handled by the patent
counsel selected by Hanmi and prosecuting of the Joint Patents outside the Territory shall be handled by the patent counsel selected by RAPT; provided, however, that RAPT shall have the right to designate, in its sole discretion and at
its sole expense, legal counsel to oversee worldwide Prosecution of all Joint Patents, including the review of all filings and material communications pertaining to the Prosecution of Joint Patents under this Section 9.4(a) (Joint Patents). .

 (b)    Hanmi Patents. Hanmi will have the sole right and authority with respect to Hanmi Patents in any
jurisdiction, including Prosecution and enforcement. Hanmi will be responsible for all costs incurred by it (including all Patent Prosecution Costs) in the course of Prosecuting and enforcing such Hanmi Patents. 

(c)    Step-In Rights for Joint Patents and Certain Hanmi Patents. If Hanmi
determines in its sole discretion to abandon, cease prosecution of or otherwise not file or maintain any Joint 

  
 - 32 - 

 
Patent or any Hanmi Patent that claims the Compound (including any composition, formulation or use thereof) in any jurisdiction in the Territory, then Hanmi will provide RAPT written notice of
such determination [***] before any deadline [***] for taking action to avoid abandonment (or other loss of rights) and will provide RAPT with the opportunity to prepare, file, prosecute and maintain such Joint Patent or Hanmi Patent, as applicable,
in such jurisdiction. The Prosecuting Party will provide the other Party reasonable opportunity to review and comment on such prosecution efforts regarding such Joint Patent or Hanmi Patent, as applicable, and such other Party will provide the
Prosecuting Party reasonable assistance in such efforts. The Prosecuting Party will provide the other Party with a copy of all material communications from any patent authority in the applicable jurisdictions regarding such Joint Patent or Hanmi
Patent, as applicable, being prosecuted by such Party, and will provide the other Party drafts of any material filings or responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses
so that such other Party may have an opportunity to review and comment thereon. In particular, each Party agrees to provide the other Party with all information necessary or desirable to enable the other Party to comply with the duty of candor/duty
of disclosure requirements of any patent authority. Unless the Parties agree otherwise, each Party will bear its own internal costs and the Patent Prosecution Costs that it incurs with respect to the Prosecution of such Joint Patents or Hanmi
Patents, as applicable. 
 9.5    Infringement of RAPT Patent Rights by Third Parties. 

(a)    Notification. The Parties will promptly notify each other of any actual, threatened, alleged or suspected
infringement in the Field by a Third Party of the RAPT Patent Rights, Joint Patents or any Hanmi Patent that claims the Compound (including any composition, formulation or use thereof, and further including the use of the Compound in combination
with a Hanmi proprietary compound to treat any disease), including by the manufacture, sale or use of a product identical or similar to a Compound or Product (an “Infringement”). A notice with respect to a Product that expressly
references this Section 9.5(a) (Notification) will be deemed, solely for purposes of this Section 9.5 (Infringement of RAPT Patent Rights by Third Parties), to describe an act of Infringement, regardless of its content. As permitted by
Applicable Law, each Party will promptly notify the other Party in writing of any such Infringement of which it becomes aware, and will provide evidence in such Party’s possession and control demonstrating such Infringement. In particular, each
Party will notify and provide the other Party with copies of any allegations of patent invalidity, unenforceability or non-infringement of any RAPT Patent Rights Covering a Compound or Product (including
methods of use or manufacture thereof). Such notification and copies will be provided by the Party becoming aware of such Infringement to the other Party as soon as practicable and, unless prohibited by Applicable Law, [***] after the receiving
Party becomes aware of such Infringement. Such notification and copies will be sent by facsimile and overnight courier to Hanmi at the address set forth below, and to RAPT at the address specified in Section 17.5 (Notices). 

[***] 

(b)    Infringement of RAPT Patents. Hanmi will have the first right, but not the obligation, to bring and control,
at its expense, an appropriate suit or other action before any government or private tribunal against any person or entity allegedly engaged in any Infringement in the Territory (a “Territory Infringement Action”) of any RAPT Patent
to remedy the Infringement (or to settle or otherwise secure the abatement of such Infringement) in the Territory, with outside counsel that Hanmi may engage subject to prior notice to RAPT. RAPT will have the right, at its own expense and by
counsel of its choice, to be represented in any Territory Infringement Action with respect to a RAPT Patent (“Product Specific Territory Infringement Action”). At Hanmi’s request, RAPT will join any Product
Specific Territory Infringement Action as a party [***] if doing so is necessary for the 

  
 - 33 - 

 
purposes of establishing standing or is otherwise required by Applicable Law to pursue such action. Hanmi will have a period of [***] after its receipt or delivery of notice and evidence pursuant
to Section 9.5(a) (Notification) to elect to so enforce such RAPT Patents in the applicable jurisdiction in the Territory (or to settle or otherwise secure the abatement of such Infringement), provided, however, that such period
will be more than [***] to the extent Applicable Law prevents earlier enforcement of such RAPT Patents and such period will be less than [***] to the extent that a delay in bringing an action to enforce the applicable RAPT Patents against such
alleged Third Party infringer would limit or compromise the remedies (including monetary and injunctive relief) available against such alleged Third Party infringer. In the event Hanmi does not so elect (or settle or otherwise secure the abatement
of such Infringement) within the aforementioned period of time or [***] before the time limit, if any, for the filing of a Product Specific Territory Infringement Action, whichever is sooner, it will so notify RAPT in writing and in the case where
RAPT then desires to commence a suit or take action to enforce the applicable RAPT Patents with respect to such Infringement in the applicable jurisdiction in the Territory, the Parties will confer and RAPT will have the right to commence such a
suit or take such action to enforce the applicable RAPT Patents, at RAPT’s expense. Each Party will provide to the Party enforcing any such rights under this Section 9.5(b) (Infringement of RAPT Patents) reasonable assistance in such
enforcement, at such enforcing Party’s request and expense, including joining such action as a party plaintiff if required by Applicable Law to pursue such action. The enforcing Party will keep the other Party regularly informed of the status
and progress of such enforcement efforts, and will reasonably consider the other Party’s comments on any such efforts, provided, however, if the enforcing Party is Hanmi, Hanmi shall be required to comply with all reasonable
directions and instructions of RAPT. 
 (c)    Settlement. Without the prior written consent of the other Party
(not to be unreasonably withheld, conditioned or delayed), neither Party will settle any Product Specific Territory Infringement Action in any manner that would adversely affect a RAPT Patent or that would limit or restrict the ability of Hanmi (or
its Affiliates or Sublicensees, as applicable) to sell Products in the Field anywhere in the Territory. 

(d)    Expenses and Recoveries. A Party bringing a Product Specific Territory Infringement Action under this
Section 9.5 (Infringement of RAPT Patent Rights by Third Parties) against any Third Party engaged in Infringement of the RAPT Patents in the Territory will be solely responsible for any expenses incurred by such Party as a result of such
Product Specific Territory Infringement Action. If such Party recovers monetary damages from such Third Party in such Product Specific Territory Infringement Action, such recovery will first be applied to all out-of-pocket costs and expenses incurred by such Party in connection therewith, including attorneys’ fees. If after such reimbursement any funds remain from such damages, such funds will be [***]. If a
Party bringing a Product Specific Territory Infringement Action recovers [***]. If a Party bringing a Product Specific Territory Infringement Action recovers [***]. 

9.6    Infringement of Joint Patents and Hanmi Patents by Third Parties. 

(a)    Hanmi will have the first right, but not the obligation, to bring at its expense an appropriate suit or other
action against any Third Party allegedly engaged in any Infringement of Joint Patents, Joint Patent or any Hanmi Patent in the Territory with the outside counsel that Hanmi may engage subject to prior notice to RAPT. Hanmi will have a period of
[***] after its receipt or delivery of notice of such Infringement to elect to so enforce such Joint Patent or any Hanmi Patent that claims the Compound (including any composition, formulation or use thereof, and further including the use of the
Compound in combination with a Hanmi proprietary compound to treat any disease) (or to settle or otherwise secure the abatement of such Infringement), provided, however, that such period will be more than [***] to the extent Applicable
Law prevents earlier enforcement of such 

  
 - 34 - 

 
Joint Patents or such Hanmi Patents and such period will be less than [***] to the extent that a delay in bringing an action to enforce the applicable Joint Patents or Hanmi Patents against such
alleged Third Party infringer would limit or compromise the remedies (including monetary and injunctive relief) available against such alleged Third Party infringer. In the event Hanmi does not so elect (or settle or otherwise secure the abatement
of such Infringement) within the aforementioned period of time or [***] before the time limit, if any, for the filing of an Territory Infringement Action, whichever is sooner, it will so notify RAPT in writing and in the case where RAPT then desires
to commence a suit or take action to enforce the applicable Joint Patents with respect to such Infringement, the Parties will confer and RAPT will have the right to commence such a suit or take such action to enforce the applicable Joint Patents and
Hanmi Patents that claim the Compound (including any composition, formulation or use thereof, and further including the use of the Compound in combination with a Hanmi proprietary compound to treat any disease), at RAPT’s expense, subject to
prior notice to Hanmi. Each Party will provide to the Party enforcing any such rights under this Section 9.6(a) reasonable assistance in such enforcement, at such enforcing Party’s request and expense, including joining such action as a
party plaintiff if required by Applicable Law to pursue such action. The enforcing Party will keep the other Party regularly informed of the status and progress of such enforcement efforts, and will reasonably consider the other Party’s
comments on any such efforts. 
 (b)    Without the prior written consent of the other Party (not to be unreasonably
withheld, conditioned or delayed), neither Party will settle any claim, suit or action that it may bring with respect to a Joint Patent in the Territory. 

(c)    A Party bringing a claim, suit or action under Section 9.6(a) against any Third Party engaged in Infringement
of any Joint Patent in the Territory will be solely responsible for any expenses incurred by such Party as a result of such claim, suit or action. If such Party recovers monetary damages from such Third Party in such suit or action, such recovery
will first be applied to all out-of-pocket costs and expenses incurred by such Party in connection therewith, including attorneys’ fees. If after such reimbursement
any funds remain from such damages, such funds will be [***]. 
 9.7    Third Party Rights. 

(a)    The Parties will promptly notify each other in writing (i) if either Party receives any written allegation
that any activity pursuant to this Agreement infringes the Patent rights or technology of any Third Party in the Territory (the “Third Party Technology”)(ii) if either Party desires to obtain a license or otherwise pursue a defense
or settlement with respect to any Third Party Technology that the notifying Party believes may be necessary either for the purpose of overcoming a potential Infringement of such Third Party Technology or otherwise in connection with the exercise by
Hanmi of its rights to manufacture, Develop or Commercialize Products or Compound in the Field in the Territory in accordance with this Agreement (such Third Party Technology, the “Necessary Third Party Technology”) or (iii) if
either Party desires to obtain a license with respect to any Third Party Technology that the notifying Party believes may be useful in connection with the exercise by Hanmi of its rights to manufacture, Develop or Commercialize Products or Compound
in the Field in the Territory in accordance with this Agreement (such Third Party Technology, the “Useful Third Party Technology”). 

(b)    Subject to Sections 9.7(c) and (d), with respect to any Third Party Technology, Hanmi will have the first right to
seek a license, at its expense, subject to any applicable reduction of royalties payable to RAPT pursuant to Section (d) (Third Party Payments), to the extent that such Third Party Technology Covers or may Cover the manufacture, Development or
Commercialization of Products or Compound in the Field in the Territory in accordance with this Agreement, including but not limited to the composition, formulation, method of use, method of manufacture of any Compound and/or Product in the Field in
the Territory, and/or is an improvement to any Compound and/or Product in the Field in the Territory. For clarity, Hanmi’s first right, as described in the previous sentence, does not apply to any Third Party Technology outside the Territory,
nor to any Third Party Technology in the Territory that claim only a method of using the Compound or Product outside the Field, which rights RAPT may in its sole discretion license or acquire directly from such Third Party. In the event that Hanmi
does not obtain the 

  
 - 35 - 

 
license in accordance with the preceding sentence of this Section 9.7(b) within [***] of the delivery of the applicable notice in accordance with Section 9.7(a), then RAPT may in its
sole discretion obtain the license or title with respect to such Third Party Technology, in which case RAPT may negotiate the terms and conditions of such license or acquisition, and make all the payments due pursuant to any such agreement with such
Third Party respect to such Third Party Technology (with the Third Party Technology required by Hanmi with respect to Compound and Products, solely to the extent such Third Party Technology becomes Controlled by RAPT as a result of such agreement,
being included in the RAPT Patent Rights and RAPT Know-How and sublicensed by RAPT to Hanmi under Section 7.1 (License to Hanmi)). 

(c)    Notwithstanding Section 15.3 (Indemnification Procedures), without the prior written consent of Hanmi (not to
be unreasonably withheld, conditioned or delayed), RAPT will not settle any claim under this Section 9.7 (Third Party Rights) in any manner that would (i) limit or restrict the ability of Hanmi (or its Affiliates or Sublicensees, as
applicable) to sell Products in the Field anywhere in the Territory or (ii) impose any obligation, restriction or limitation on Hanmi. 

(d)    The Parties will cooperate in all respects with one another in prosecuting or defending any action pursuant to this
Section 9.7 (Third Party Rights). 
 9.8    Reexaminations, Oppositions and Related Actions. 

(a)    The Parties will promptly notify each other in the event that any Third Party files in the Territory any paper in a
court, patent office or other government entity, seeking to invalidate, reexamine, oppose or compel the licensing of any RAPT Patent or threatens to file such paper with respect to any RAPT Patent or any RAPT Patent contemplated to be used or
practiced under in the conduct of the Development (any such Third Party action being a “Patent Challenge”). 

(b)    RAPT will have the first right to bring and control, at its expense, any effort in defense of such a Patent
Challenge against a RAPT Patent within the Territory, except in the case where such Patent Challenge is made in connection with an Infringement Action in which case the enforcing Party in the Infringement Action will have the first right to bring
and control the defense of such Patent Challenge and such Patent Challenge will be considered part of the Infringement Action under this Article 9 (Patent Prosecution and Enforcement). In the case where Hanmi controls the defense of such Patent
Challenge, RAPT will have the right, at its own expense and by counsel of its choice, to be represented in any such effort. If RAPT fails to take action to defend such Patent Challenge within [***] of the time limit for bringing such defense [***],
then Hanmi will have the right, but not the obligation, to bring and control any effort in defense of such Patent Challenge at its own expense. 

9.9    Disclosure of Inventions. To the extent relating to Compound or Product (including methods of making
a Compound and methods of using a Compound to prevent or treat a disease), each Party will promptly disclose to the other Party all Inventions of which such Party becomes aware, including Inventions by its, its Affiliates’ or its
Sublicensee’s) employees describing Joint Inventions and RAPT-Owned Inventions and Hanmi-Owned Inventions, as applicable. Each Party will also respond promptly to reasonable requests from the other Party for more Information relating to such
Inventions. 
 9.10    Personnel Obligations. Prior to receiving any Confidential Information or beginning
work under this Agreement relating to any research, Development or Commercialization of a Compound or a Product, each employee, agent or independent contractor of each Party, its Affiliates and Sublicensees and the Third Party subcontractors of any
of the foregoing will be bound in writing by non-disclosure and invention assignment obligations that are consistent with the obligations of the Parties under this Agreement, including with respect to all
Inventions and Information.
 9.11    No Challenge. Notwithstanding any other provision of this Agreement
to the contrary, if Hanmi or its Affiliate challenges, or knowingly participates with or assists a Third Party (except as required 

  
 - 36 - 

 
by Applicable Law) to challenge the validity, enforceability, patentability and/or scope of any claim within the RAPT Patent Rights in a court or patent office or other governmental agency, RAPT
may terminate the license granted under this Agreement. 
 9.12    Further Action. Each Party will, upon
the reasonable request of the other Party, provide such assistance and execute such documents as are reasonably necessary for such Party to exercise its rights and perform its obligations pursuant to this Article 9 (Patent Prosecution and
Enforcement); provided, however, that neither Party will be required to take any action pursuant to Article 9 (Patent Prosecution and Enforcement) that such Party reasonably determines in its sole judgment and discretion conflicts with
or violates any applicable court or government order or decree or Applicable Law. 
 10. TRADEMARKS 

10.1    Product Trademarks. Except as expressly provided in this Article 10 (Trademarks), (a) Hanmi shall be
solely responsible for the selection (including the creation, searching and clearing), registration, maintenance, policing and enforcement of all trademarks developed for use in connection with the marketing, sale or distribution of Products in the
Field in the Territory (each, a “Product Mark”), and Hanmi shall own all Product Marks, and all trademark registrations for said marks. 

10.2    Branding and Trademarks. Notwithstanding Section 10.1 (Product Trademarks), at any time
after the Effective Date, RAPT may provide Hanmi with RAPT’s global branding strategy for the Product (the “Global Branding Strategy”). Within [***] thereafter, Hanmi shall develop and submit to the JSC a local branding
strategy for the Product that is consistent with the Global Branding Strategy (“Local Branding Strategy”); provided, however, that if Hanmi reasonably believes that direct adoption and implementation of the Global
Branding Strategy into the Local Branding Strategy would insufficiently protect Product Marks for the Product in the Territory or causes Hanmi to be non-compliant with applicable trademark or labeling laws in
the Territory, Hanmi shall be entitled to propose relevant amendments or revisions to the Global Branding Strategy to be incorporated in the Local Branding Strategy to the extent such changes or revisions are necessary for Hanmi to so protect
Product Marks or so comply with applicable laws in the Territory, in which case, RAPT shall consider such proposal in good faith and shall not unreasonably withhold its approval of such proposal only based on conflict with its Global Branding
Strategy. The Parties may, through the JSC, discuss the development and adoption of branding elements, such as key distinctive colors, logos, images, symbols, and Trademarks to be used in in connection with the Commercialization of the Product in
the Field; provided, however, that Hanmi shall not adopt or use, and shall not permit its Affiliates or Sublicensees to adopt or use, any such branding elements in the Territory without RAPT’s prior written approval, which RAPT may withhold
[***]. As between the Parties, RAPT shall be the owner and file for the protection of Product Marks for the Product that are used in pursuant to the Global Branding Strategy. 

10.3    Use of Name. Neither Party shall, without the other Party’s prior written consent, use any
trademarks or other marks of the other Party (including the other Party’s corporate name), trademarks, advertising taglines or slogans confusingly similar thereto, in connection with such Party’s marketing or promotion of Products under
this Agreement or for any other purpose, except as may be expressly authorized in writing in connection with activities under this Agreement and except to the extent required to comply with Applicable Law or in connection with a Party exercising its
rights under this Agreement, including with respect to Prosecution of Patents and the submission of Clinical Trial data to Regulatory Authorities. 

10.4    Further Actions. Each Party shall, upon the reasonable request of the other Party, provide such
assistance and execute such documents as are reasonably necessary for such Party to exercise its rights and/or perform its obligations pursuant to this Article 10 (Trademarks); provided, however, that neither Party shall be required to
take any action pursuant to Article 10 (Trademarks) that such Party reasonably determines in its sole judgment and discretion conflicts with or violates any applicable court or government order or decree or Applicable Law.

 11. NON-COMPETITION AND EXCLUSIVITY 

11.1    Non-Competition; Exclusivity. RAPT agrees that it will not
work independently of this Agreement within the Territory during the Term for itself or with any Third Party (including the grant of any license or option to any Third Party) or enable a Third Party with respect to discovery, research, development
and/or commercialization activities of [***]. Hanmi agrees that it will not work independently of this Agreement within the Territory during the Term for itself or with any Third Party (including the grant of any license or option to any Third
Party) or enable a Third Party with respect to discovery, research, development and/or commercialization activities of [***]. 
 12.
CONFIDENTIALITY 
 12.1    Confidentiality. Except to the extent expressly authorized by this
Agreement or otherwise agreed in writing by the Parties, each Party (the “Receiving Party”) agrees that, for the Term and for [***], it shall keep confidential and shall not publish or otherwise disclose and shall not use for any
purpose other than as provided for in this Agreement (which includes the exercise of any rights or the performance of any obligations hereunder) any Confidential Information furnished to it by the other Party (the “Disclosing
Party”) pursuant to this Agreement except for that portion of such Information that the Receiving Party can demonstrate by competent written proof: 

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

(d)    is subsequently disclosed to the Receiving Party or any of its Affiliates by a Third Party without obligations of
confidentiality to the Disclosing Party with respect thereto; or 
 (e)    is subsequently independently discovered or
developed by the Receiving Party or its Affiliate without the aid, application, or use of Confidential Information of the Disclosing Party. 
 To the extent
relating specifically to Compound or Products, for so long as this Agreement is in effect with respect to such Compound and Products, (i) all Information generated solely by RAPT during the research, Development, manufacturing, and/or
Commercialization of Compound and/or Products after the Effective Date shall be treated as the Confidential Information of RAPT, (ii) subject to Section 4.3 (Information Transfer to RAPT), all Information generated solely by Hanmi during
the research, Development, manufacturing, and/or Commercialization of Compound and/or Products shall be treated as the Confidential Information of Hanmi and (iii) all Information generated jointly by the parties during the research,
Development, manufacturing, and/or Commercialization of Compound and/or Products after the Effective Date shall be treated as the Confidential Information of both Parties. Each Party agrees that it shall provide or permit access to Confidential
Information of the other Party only to the receiving Party’s Affiliates, employees, consultants, advisors and permitted subcontractors, licensees and sublicensees, and to the employees, consultants, advisors and permitted subcontractors,
licensees and sublicensees of the receiving Party’s Affiliates, who have a need to know such Confidential Information to assist the receiving Party with the activities contemplated or required of it or permitted by this Agreement and who are
subject to obligations of confidentiality and non-use with respect to such Confidential Information substantially similar to the obligations of confidentiality and
non-use of the receiving Party pursuant to this Section 12.1 (Confidentiality); provided that each Party shall remain responsible for any failure by its Affiliates, and its and its
Affiliates’ respective employees, consultants, advisors and permitted subcontractors, licensees and sublicensees, to treat such Confidential Information as required under this Section 12.1 (Confidentiality) (as if such Affiliates,
employees, consultants, advisors and permitted subcontractors, licensees and sublicensees were Parties directly bound to the requirements of this Section 12.1 (Confidentiality)). 

  
 - 38 - 

 12.2    Authorized Disclosure. Each Party may disclose
Confidential Information belonging to the other Party to the extent such disclosure is reasonably necessary in the following situations: 

(a)    filing or Prosecuting Patents in accordance with Article 9 (Patent Prosecution and Enforcement), provided,
however, that such disclosure would not result in the Disclosing Party breaching any confidentiality obligations to a Third Party; 

(b)    subject to Section 12.3 (Publicity; Terms of Agreement), submitting Regulatory Filings and other filings with
Governmental Authorities (including Governmental Authorities), including filings with the MFDS or NMPA, as necessary for the Development or Commercialization of a Product, as required in connection with any filing, application or request for
Regulatory Approval; provided, however, that reasonable measures will be taken to assure confidential treatment of such information; 

(c)    prosecuting or defending litigation; 

(d)    subject to Section 12.3 (Publicity; Terms of Agreement), complying with Applicable Law, including regulations
promulgated by securities exchanges; 
 (e)    disclosure to its Affiliates, employees, agents, independent contractors,
licensors and any Sublicensees of the RAPT Technology only on a need-to-know basis and solely in connection with the performance of this Agreement, provided that
each disclosee must be bound by written obligations of confidentiality and non-use at least as equivalent in scope as and no less restrictive than those set forth in this Article 12 (Confidentiality) prior to
any such disclosure, provided further that the term of such disclosee’s obligations regarding the use and disclosure of Confidential Information shall be as long as can be reasonably negotiated with such disclosee, but in any event no
less than [***] after the date of disclosure to the disclosee; 
 (f)    disclosure of the material terms of this
Agreement to any bona fide potential or actual investor, stockholder, investment banker, acquirer, merger partner, other potential or actual financial partner, collaborator or licensee, as well as their legal, financial, tax and other advisors;
provided that the disclosing Party will use reasonable efforts to make each disclosee bound by obligations of confidentiality and non-use at least as equivalent in scope as and no less restrictive than
those set forth in this Article 12 (Confidentiality) prior to any such disclosure, provided further that the term of such disclosee’s obligations regarding the use and disclosure of such material terms shall be as long as can be
reasonably negotiated with such disclosee; provided further that notwithstanding anything to the contrary contained in this Agreement, [***] shall be disclosed to [***], in each case, [***]; 

(g)    disclosure of the stage of Development of Products under this Agreement to any bona fide potential or actual
investor, stockholder, investment banker, acquirer, merger partner, other potential or actual financial partner, collaborator or licensee, as well as their legal, financial, tax and other advisors; provided that each disclosee must be bound
by obligations of confidentiality and non-use at least as equivalent in scope as and no less restrictive than those set forth in this Article 12 (Confidentiality) prior to any such disclosure, provided
further that the term of such disclosee’s obligations regarding the use and disclosure of such Confidential Information shall be as long as can be reasonably negotiated with such disclosee; 

(h)    disclosure pursuant to Section 12.5 (Publication and Listing of Clinical Trials and Compliance with Other
Policies, Orders and Agreements); and 

  
 - 39 - 

 Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the
other Party’s Confidential Information pursuant to Sections 12.2(a), 12.2(c) or 12.2(d), it will, except where impracticable, give reasonable advance notice to the other Party of such disclosure and use reasonable efforts to secure confidential
treatment of such information. In any event, the Parties agree to take all reasonable action to avoid disclosure of Confidential Information hereunder in any manner that would breach this Agreement. 

Nothing in Sections 12.1 (Confidentiality) or 12.2 (Authorized Disclosure) shall limit either Party in any way from disclosing to any Third
Party such Party’s U.S. or foreign income tax treatment and the U.S. or foreign income tax structure of the transactions relating to such Party that are based on or derived from this Agreement, as well as all materials of any kind (including
opinions or other tax analyses) relating to such tax treatment or tax structure, except to the extent that nondisclosure of such matters is reasonably necessary in order to comply with applicable securities laws. 

12.3    Publicity; Terms of Agreement. 

(a)    The Parties agree that the material terms of this Agreement are the Confidential Information of both Parties,
subject to the special authorized disclosure provisions set forth in Section 12.2 (Authorized Disclosure) and this Section 12.3 (Publicity; Terms of Agreement). Except as set forth in Sections 12.3(b) and 12.3(c), each Party agrees not to
issue any press release or other public announcement disclosing the terms of this Agreement or the transaction contemplated hereby without providing [***] prior written notice to the other Party, and obtaining prior written consent of the other
Party. RAPT agrees to provide Hanmi at least [***] notice prior to issuing any press release relating to the execution of this Agreement. 

(b)    Each Party may disclose the terms of this Agreement in the case of a press release or governmental filing
(including any prospectus in connection with an IPO or other securities offering or filing) to the extent required by Applicable Law (where reasonably advised by the disclosing Party’s counsel), provided that the disclosing Party shall
give prior advance notice (to the extent it reasonably can) of the proposed text of such release or filing to the other Party for its prior review but shall not be required to obtain approval therefor. 

(c)    The Parties acknowledge that either or both Parties may be obligated to file under Applicable Law a copy of this
Agreement with the SEC or other Government Authorities. Each Party shall be entitled to make such a required filing, provided that it requests confidential treatment of at least the financial terms and sensitive technical terms hereof and
thereof to the extent such confidential treatment is reasonably available to such Party. In the event of any such filing, each Party will provide the other Party with a copy of this Agreement marked to show provisions for which such Party intends to
seek confidential treatment not less than [***] prior to such filing (and any revisions to such portions of the proposed filing a reasonable time prior to the filing thereof), and shall reasonably consider the other Party’s comments thereon to
the extent consistent with the legal requirements, with respect to the filing Party, governing disclosure of material agreements and material information that must be publicly filed, and shall only disclose Confidential Information which it is
advised by counsel or the applicable Governmental Authority is legally required to be disclosed. No such notice shall be required under this Section 12.3(c) if the substance of the description of or reference to this Agreement contained in the
proposed filing has been included in any previous filing made by either Party hereunder or otherwise approved by the other Party. 

(d)    Each Party shall require each of its Affiliates and private investors to which Confidential Information of the
other Party is disclosed as permitted hereunder to comply with the covenants and restrictions set forth in Sections 12.1 (Confidentiality) through Section 12.3 (Publicity; Terms of Agreement) as if each such Affiliate and each such investor
were a Party to this Agreement and shall be fully responsible for any breach of such covenants and restrictions by any such Affiliate or investor.

 12.4    Publications. 

(a)    Neither Party shall publicly present or publish results of studies carried out under this Agreement (each such
presentation or publication a “Publication”) without the opportunity for prior review and approval by the other Party, except to the extent otherwise required by Applicable Law, in which case Section 12.3 (Publicity; Terms of
Agreement) shall apply with respect to disclosures required by the SEC or other Governmental Authorities or stock exchanges and/or for regulatory filings. The submitting Party shall provide the other Party the opportunity to review any proposed
Publication at least [***] prior to the earlier of its presentation or intended submission for publication. The submitting Party agrees, upon request by the other Party, not to submit or present any Publication until the other Party has had [***] to
comment on any material in such Publication. The submitting Party shall consider the comments of the other Party in good faith, but will retain the sole authority to submit the manuscript for Publication; provided that the submitting Party
agrees to delay such Publication as necessary to enable the Parties to file a Patent if such Publication might adversely affect such Patent. The submitting Party shall provide the other Party a copy of the Publication at the time of the submission
or presentation. Notwithstanding the foregoing, Hanmi shall not have the right to publish or present RAPT’s Confidential Information without RAPT’s prior written consent, and RAPT shall not have the right to publish or present Hanmi’s
Confidential Information without Hanmi’s prior written consent. Each Party agrees to acknowledge the contributions of the other Party, and the employees of the other Party, in all publications as scientifically appropriate. This
Section 12.4 (Publications) shall not limit and shall be subject to Section 12.5. 
 (b)    Nothing contained
in this Section 12.4 shall prohibit the inclusion of information in a patent application claiming, and in furtherance of, the manufacture, use, sale or formulation of a Compound, provided that the
non-filing Party is given a reasonable opportunity to review, comment upon and/or approve the information to be included prior to submission of such patent application, where and to the extent required by
Article 9 (Patent Prosecution and Enforcement) hereof. Notwithstanding the foregoing, the Parties recognize that either Party may [***]. The Parties recognize that [***]; provided that each Party shall require, and shall require its
Affiliates and Sublicensees to require, that [***] comply with Section 12.4(a) to prevent publication prior to the filing of relevant patent applications and to ensure that no Confidential Information of either Party is disclosed. 

12.5    Publication and Listing of Clinical Trials and Compliance with other Policies, Orders and
Agreements. Each Party agrees to comply, with respect to the Compound and Products and to the extent applicable to its activities conducted under this Agreement, with (a) the Pharmaceutical Research and Manufacturers of
America (PhRMA) Guidelines on the listing of Clinical Trials and the Publication of Clinical Trial results, (b) any applicable court order, stipulations, consent agreements and settlements entered into by such Party, and (c) each
Party’s policy concerning Clinical Trials Registration and Disclosure of Results as amended from time to time and other policies adopted by such Party for the majority of its other pharmaceutical products with regard to the same (to the extent
the such policies either are not in direct conflict with the documents referred to in clauses (a) and (b) above and to the extent such policies are provided by to the other Party in writing at least [***] prior to requiring their implementation
under this Agreement and to the extent such policies do not conflict with the other provisions of this Agreement or require RAPT to violate any Applicable Law). 

12.6    Effect of Change of Control of RAPT. If RAPT or any of its Affiliates merges or consolidates
with, is otherwise acquired by, or acquires, a Third Party (including through a Change of Control Transaction), RAPT shall take necessary steps [***] as part of this Agreement.

 13.    TERM AND TERMINATION 

13.1    Term. This Agreement shall become effective as of the Effective Date and, unless earlier terminated
pursuant to this Article 13 (Term and Termination), shall continue until expiration of all royalty payment obligations under Section 8.4 (Royalty Payments to RAPT) herein (the “Term”). 

13.2    Termination by Hanmi With or Without Cause. 

(a)    Termination by Hanmi Without Cause. Hanmi has the right to terminate this Agreement as a whole or in its
sole discretion on a country-by-country and/or Product-by-Product basis, effective upon
[***] prior written notice to RAPT if prior to submission of any NDA for the Product in the Territory or [***] prior written notice to RAPT thereafter, except that Hanmi will wind down any on-going Development
(including any Clinical Trial for the applicable Product being conducted by or on behalf of Hanmi) and any Commercialization activities for applicable Product, consistent with Applicable Law. 

(b)    Termination by Hanmi for Safety Reasons. Hanmi has the right to terminate this Agreement on a Product-by-Product basis as to the entire Territory or with respect to any country (on a
country-by-country basis) upon written notice to RAPT based on Safety Reasons. Upon such termination for Safety Reasons, Hanmi shall be responsible, [***] for the
wind-down of any Development of applicable Product (including any Clinical Trials for the applicable Product being conducted by or on behalf of Hanmi, its Affiliates or Sublicensees) and any Commercialization activities for applicable Product. Such
termination shall become effective upon the date that Hanmi notifies RAPT in writing that such wind-down is complete. 

(c)    Termination by Hanmi for RAPT’s Abandonment of Development of Product. In the event
(i) RAPT has affirmatively and definitively decided to permanently cease the research, development, manufacture and commercialization of the Product in all jurisdictions other than the Territory, in which case RAPT shall provide Hanmi with
written notice of cessation within [***] after the date of such affirmative and definitive decision, or (ii) RAPT has not engaged in any activities relating to the research, development, manufacture and commercialization of the Product for a
period of [***], Hanmi has the right to terminate this Agreement (x) within [***] after receipt of written notice from RAPT of such cessation or (y) after the date that RAPT has not engaged in any activities relating to the research,
development, manufacture and commercialization of the Product for a period of [***], as applicable. 

(d)    Termination by Hanmi for Representations and Warranties. If, as of the date on which [***], a
representation and warranty described in Section 14.2(d) or Section 14.2(g) would be inaccurate if made at that time, then Hanmi shall have the right to terminate this Agreement by delivery of [***] written notice to RAPT; provided,
however, that such inaccuracy shall not be deemed a breach of this Agreement. 
 13.3    Termination by Either
Party for Breach. 
 (a)    Subject to Sections 13.3(b), (c) and (d), either Party may terminate this Agreement with
respect to any Product (on a Product-by-Product basis) as to the entire Territory or with respect to any country (on a country-by-country basis), in the event the other Party materially breaches this Agreement, and such breach shall have continued for [***] after written notice shall have been provided to the breaching Party
by the non-breaching Party requiring such breach to be remedied and stating an intention to terminate if not so cured (a “Termination Notice”). Except as set forth in Section 13.3(b), any
such termination shall become effective at the end of such period unless the breaching Party has cured any such breach prior to the expiration of such period. Any such Termination Notice shall [***]. 

(b)    If the alleged breaching Party disputes the existence or materiality of a breach

  
 - 42 - 

 
specified in a Termination Notice provided by the other Party in accordance with Section 13.3(a), and such alleged breaching Party provides the other Party notice of such dispute before the
expiration of the cure period after receiving such Termination Notice, then the non-breaching Party shall not have the right to terminate this Agreement under Section 13.3(a) with respect to the
applicable Product and country or countries unless and until arbitrators, in accordance with Article 16 (Dispute Resolution), have determined that the alleged breaching Party has materially breached this Agreement with respect to such Product and
country or countries. 
 (c)    If the alleged breaching Party provides notice of a dispute pursuant to
Section 13.3(b), [***] during the period between the notice of termination under this Section 13.3 and the effective date of termination until such dispute is resolved, then upon such resolution [***]. 

13.4    Termination for Insolvency. A Party shall have the right to terminate this Agreement upon written
notice 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 within [***] 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). 

13.5    Limitations on Termination Remedy. For avoidance of doubt, any termination under this Article 13
(Term and Termination) with respect to the Products and/or Compound in any one country within the Territory shall have no effect on and shall not in any way limit the licenses granted under this Agreement to Hanmi for Products and/or Compound in the
other countries within the Territory. 
 13.6    Effects of Termination of this Agreement by Hanmi Without
Cause, for Safety Reasons or Representations and Warranties, or by RAPT for Breach or Insolvency. Upon termination of this Agreement by Hanmi under Section 13.2(a) (Termination by Hanmi Without Cause), Section 13.2(b) (Termination by
Hanmi for Safety Reasons) or Section 13.2(d) (Termination by Hanmi for Representations and Warranties) or by RAPT under Section 13.3 (Termination by Either Party for Breach) or Section 13.4 (Termination for Insolvency), or pursuant to
Section 3.1(a) with respect to a Terminated Country as provided therein, the following shall apply with respect to the Terminated Product(s) and Terminated Country(ies) (in addition to any other rights and obligations under this Agreement with
respect to such termination). 
 (a)    Licenses. The licenses granted to Hanmi in Section 7.1 (License to
Hanmi) shall terminate solely with respect to the Product(s) and country(ies) with respect to which the termination becomes effective (each such Product, a “Terminated Product”, and each such country, “Terminated
Country”) and Hanmi shall retain a non-exclusive license under Section 7.1 (License to Hanmi) to sell, offer for sale and import Products during the Commercialization Wind-Down Period in
accordance with Section 13.7(d) (including the right to sell such Products through Hanmi Sublicensees if Hanmi were using such Sublicensees to sell same prior to such termination date). To the extent such obligations existed prior to such
termination, Hanmi shall not have any Commercially Reasonable Efforts obligations thereafter with respect to the Development and Commercialization of the Terminated Product(s) and Terminated Country(ies). 

(b)    Reversion. With respect to such Terminated Country, all rights under the RAPT Technology and to all Compound
and Terminated Products shall revert to RAPT. 

  
 - 43 - 

 (c)    Covenant. Hanmi and its Affiliates shall not Develop,
manufacture or Commercialize such Compound or Terminated Products in such Terminated Country, nor shall Hanmi grant any Affiliates or Third Parties rights to do so. 

(d)    Transfer of Regulatory Filings, Regulatory Approvals and Product Marks. Promptly following the effectiveness
of any such termination, and upon RAPT’s written request, Hamni shall (and shall require its Affiliates and Sublicensees to) assign and transfer to RAPT all Regulatory Filings, Regulatory Approvals, MAAs, Pricing Approvals and Product Marks
that are Controlled and held by or under authority of Hanmi or its Affiliates or Sublicensees as of the effective date of termination, with respect to the Terminated Country(ies), and shall take such actions and execute such other instruments,
assignments and documents as may be necessary to effect the transfer to RAPT of rights under such Regulatory Filings, Regulatory Approvals, MAAs, Pricing Approvals and Product Marks. If Applicable Law prevents or delays the transfer to RAPT of
ownership of any such Regulatory Filings, Regulatory Approvals, MAAs, Pricing Approvals and Product Marks, then Hanmi will grant, and hereby does grant, to RAPT an exclusive and irrevocable right of access and right of reference to such Regulatory
Filings, Regulatory Approvals, MAAs, Pricing Approvals and Product Marks, as applicable, for Products in the Terminated Country(ies), and will reasonably cooperate to make the benefits of such Regulatory Filings, Regulatory Approvals, MAAs, Pricing
Approvals and Product Marks available to RAPT or its designee(s). 
 (e)    Wind-Down. Hanmi, its Affiliates and
Sublicensees will stop producing Terminated Products in each Terminated Country of the Territory non-terminating Party receiving termination notice, and shall be entitled to continue (the
“Commercialization Wind-Down Period”) to sell (but not to actively promote after the effective date of termination) any existing inventory of Terminated Products in each Terminated Country of the Territory for which Regulatory
Approval has been obtained (provided that commercial sale of such Terminated Products shall have commenced in each such Terminated Country prior to the applicable effective date of termination), in accordance with the terms and conditions of this
Agreement, including Article 8 (Payments).  
 (f)    Return of Confidential Information. Within [***]
after the end of the Commercialization Wind-Down Period, each Party shall destroy all tangible items comprising, bearing or containing any Confidential Information of the other Party that are in each Party’s or its Affiliates’ possession
or control, and provide written certification of such destruction, or prepare such tangible items of Confidential Information for shipment to the other Party, as the other Party may direct, at other Party’s expense; provided that the
destroying Party may retain one copy of such Confidential Information for its legal archives solely to monitor compliance with this Agreement, and provided further that destroying Party shall not be required to destroy electronic files
containing Confidential Information that are made in the ordinary course of its business information back-up procedures pursuant to its electronic record retention and destruction practices that apply to its
own general electronic files and information. 
 (g)    Transition Assistance. Hanmi agrees to cooperate with
RAPT and its designee(s), [***] to facilitate an orderly and prompt transition of the Development (and as applicable, Commercialization) activities relating to the Terminated Product(s) in the Terminated Country(ies) to RAPT and/or its designee(s)
following such termination. 
 13.7    Effects of Termination of Agreement by Hanmi With Cause or Under
Section 13.2(c) (Abandonment), 13.3 (Breach) or 13.4 (Insolvency). Upon termination of this Agreement by Hanmi under Section 13.2(c) (Termination by Hanmi for RAPT’s Abandonment of Development of Product),

shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) after learning of the claim, suit, proceeding or cause of action for which indemnity is being sought
(“Claim”) (it being understood and agreed, however, that the failure or delay by an Indemnified Party to give such notice of a Claim shall not affect the indemnification provided hereunder except to the extent the Indemnifying Party
shall have been materially prejudiced as a result of such failure or delay to give such notice). If the Indemnifying Party is not contesting the indemnity obligation, the Indemnified Party shall permit the Indemnifying Party to control and assume
the defense of any litigation relating to such claim and disposition of any such Claim unless the Indemnifying Party is also a party (or likely to be named a party) to the proceeding in which such claim is made and the Indemnified Party gives notice
to the Indemnifying Party that it may have defenses to such claim or proceeding that are in conflict with the interests of the Indemnifying Party, in which case the Indemnifying Party shall not be so entitled to assume the defense of the case. 

  
 - 49 - 

 If the Indemnifying Party does assume the defense of any Claim, it (i) shall act diligently and in good
faith with respect to all matters relating to the settlement or disposition of any Claim as the settlement or disposition relates to Parties being indemnified under this Article 15 (Indemnification and Limitation of Liability), (ii) shall cause such
defense to be conducted by counsel reasonably acceptable to the Indemnified Party, (iii) shall keep the Indemnified Party reasonably advised of the status of such Claim and the defense thereof and shall consider recommendations made by the
Indemnified Party with respect thereto and (iv) subject to the application of Section 9.7(c), shall not settle or otherwise resolve any Claim without prior notice to the Indemnified Party and the consent of the Indemnified Party if such
settlement involves anything other than the payment of money by the Indemnifying Party. The Indemnified Party shall reasonably cooperate with the Indemnifying Party in its defense of any claim for which the Indemnifying Party has assumed the defense
in accordance with this Section 15.3 (Indemnification Procedures), and shall have the right (at its own expense) to be present in person or through counsel at all legal proceedings giving rise to the right of indemnification. So long as the
Indemnifying Party is diligently defending the Claim in good faith, the Indemnified Party shall not settle any such Claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume and conduct the defense
of the Claim as provided above, (a) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to the Claim in any manner the Indemnified Party may deem reasonably appropriate
(and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (b) the Indemnifying Party will remain responsible to indemnify the Indemnified Party as provided in this Article
15 (Indemnification and Limitation of Liability).

WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY, CONTRIBUTION OR OTHERWISE, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE
MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 15.4 (LIMITATION OF LIABILITY) IS INTENDED TO OR WILL LIMIT OR RESTRICT: (A) THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF

Any arbitration award may be entered in and enforced by a court in accordance with Section 16.3 (Award). 

16.3    Award. Any award to be paid by one Party to the other Party as determined by the arbitrators as set
forth above under Section 16.2 (Arbitration) shall be promptly paid in Dollars free of any tax, deduction or offset; and any costs, fees or taxes incident to enforcing the award shall, to the maximum extent permitted by law, be charged against

or on behalf of the Bankrupt Party, if not previously delivered as provided under clause (i) above. All rights of the Parties under this Section 17.3 and under Section 365(n) of Title 11 are in addition to and not in substitution of
any and all other rights, powers, and remedies that each Party may have under this Agreement, Title 11, and any other Applicable Law. The non-Bankrupt Party shall have the right to perform the obligations of

(d)    In the event that after the Effective Date [***], RAPT will use Commercially Reasonable Efforts [***]. 

(e)    Notwithstanding anything to the contrary in Article 9 (Patent Prosecution and Enforcement), in the event that RAPT
is the Bankrupt Party, Hanmi may take appropriate actions in connection with the filing, prosecution, maintenance and enforcement of any RAPT Patent Rights in the Territory licensed or assigned to Hanmi under this Agreement without being required to
consult with RAPT before taking any such actions, provided that such actions are consistent with this Agreement. 

17.4    Force Majeure. Each Party shall be excused from the performance of its obligations under this
Agreement to the extent that such performance is prevented by force majeure (defined below) and the nonperforming Party promptly provides notice of such prevention to the other Party. Such excuse shall be continued so long as the condition
constituting force majeure continues. The Party affected by such force majeure also shall notify the other Party of the anticipated duration of such force majeure, any actions being taken to avoid or minimize its effect after such occurrence, and

 17.6    Independent Contractors. Each Party shall act solely as an
independent contractor, and nothing in this Agreement shall be construed to give either Party the power or authority to act for, bind, or commit the other Party in any way. Nothing herein shall be construed to create the relationship of partners,
principal and agent, or joint-venture partners between the Parties. 
 17.7    Maintenance of Records.
Each Party shall maintain complete and accurate records of all work conducted under this Agreement and all results, data and developments made pursuant to its efforts under this Agreement. Such records shall be complete and accurate and shall fully
and properly reflect all work done and results achieved in the performance of this Agreement in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes. Each Party shall maintain such records for a period of
[***] after such records are created or such longer period as may be required by Applicable Law; provided that records may be maintained for an appropriate longer period in accordance with each Party’s internal policies on record
retention in order to ensure the preservation, prosecution, maintenance or enforcement of intellectual property rights. Each Party shall keep and maintain all records required by Applicable Law with respect to Products. 

17.8    Assignment. Neither Party may assign this Agreement or assign or transfer any rights or
obligations hereunder (including the intellectual property rights licensed under this Agreement) without the prior written consent of the other, except that a Party may make such an assignment or transfer without the other Party’s consent
(i) to any Affiliate of such Party, provided that such transfer shall not adversely affect the other Party’s rights and obligations under this Agreement and that such assigning/transferring Party remains jointly and severally liable
with such Affiliate for the performance of this Agreement and/or the assigned obligations, or (ii) to any Third Party successor-in-interest or purchaser of all or
substantially all of the business or assets of such Party to which this Agreement relates [***], whether in a merger, combination, reorganization, sale of stock, sale of assets or other transaction; provided, however, that in each case
(i) and (ii) that the assigning Party provides written notice to the other Party of such assignment and the assignee shall have agreed in writing to be bound (or is otherwise required by operation of Applicable Law to be bound) in the same
manner as such assigning Party hereunder. In addition, either Party may assign its right to receive proceeds under this Agreement or grant a security interest in such right to receive proceeds under this Agreement to one or more Third Parties
providing financing to such Party pursuant to the terms of a security or other agreement related to such financing (i.e., for purposes of a)

royalty financing arrangement). Any permitted assignment shall be binding on the successors of the assigning Party. Any assignment or attempted assignment by either Party in violation of the
terms of this Section 17.8 (Assignment) shall be null, void and of no legal effect. For clarity, the provisions of this Section 17.8 (Assignment) shall not apply to or encompass sublicensing of the rights licensed to a Party under this
Agreement. 
 In the event that RAPT is acquired in a Change of Control Transaction by a Third Party (such Third Party, hereinafter referred
to as an “Acquirer”), then the intellectual property of such Acquirer held or developed by such Acquirer prior to or after such acquisition (other than intellectual property developed by such Acquirer in the course of conducting
RAPT’s activities under this Agreement) shall be excluded from the RAPT Technology, and such Acquirer (and Affiliates of such Acquirer which are not controlled by (as defined under the Affiliate definition in Article 1 (Definitions)) RAPT
itself) shall be excluded from the Affiliate definition solely for purposes of the applicable components of the RAPT Technology. For clarity, any intellectual property developed by the Acquirer in the course of conducting RAPT’s activities
under this Agreement shall be included within the RAPT Technology to the extent such intellectual property would have been so included had it been developed by RAPT. For further clarity, the Acquirer has sole discretion as to whether it will
contribute its intellectual property or know-how to RAPT’s activities and RAPT Technology under this Agreement. 

17.9    Governing Law. This Agreement shall be governed by and construed and enforced under the substantive
laws of State of New York, without regard to its choice of law principles. 
 17.10    Performance by
Affiliates. Subject to the terms and conditions of this Agreement, each Party may discharge any obligations and exercise any right hereunder through any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such
Party’s obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any breach by a Party’s Affiliate of any of such Party’s obligations under
this Agreement shall be deemed a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first proceed against such Party’s Affiliate. 

17.11    Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments,
and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement. 

17.12    Compliance with Applicable Law. Each Party shall comply with Applicable Law, including the
Anti-Corruption Laws and applicable Trade Control Laws, in the course of performing its obligations or exercising its rights pursuant to this Agreement. Neither Party (nor any of their Affiliates) shall be required under this Agreement to take any
action or to omit to take any action otherwise required to be taken or omitted by it under this Agreement if the taking or omitting of such action, as the case may be, could in its opinion violate any settlement, consent order, corporate integrity
agreement, or judgment to which it may be subject from time to time during the Term. Notwithstanding anything to the contrary in this Agreement, neither Party nor any of its Affiliates shall be required to take, or shall be penalized for not taking,
any action that such Party reasonably believes is not in compliance with Applicable Law. 

17.13    Severability. If any one or more of the provisions of this Agreement are held to be invalid or
unenforceable by an arbitrator or any court of competent jurisdiction from which no appeal can be or is taken, the provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The
Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized. 

17.14    No Waiver. Neither Party may waive or release any of its rights or interests in this Agreement
except in writing. The failure of either Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any
such term or condition. No waiver by either Party of any condition or term in any one or more instances shall be construed as a continuing waiver of suchcondition or term or of another condition or term.
