(b) Each sublicense and subcontract entered into by Licensee shall refer to and be
subordinate to this Agreement and, except to the extent the Parties otherwise agree in writing, any such sublicense and subcontract must be consistent in all material respects with the applicable terms and conditions of this Agreement. Licensee

right to enter into a license agreement directly with Licensor on substantially the same terms and conditions under which such rights and licenses were granted to such Sublicensee, provided that such Sublicensee (i) is not then in breach of its
sublicense, (ii) agrees to comply with all the terms of this Agreement to the extent applicable to the rights sublicensed to it by Licensee or its Affiliate, and (iii) such agreement does not impose any obligations upon Licensor that

(b) In the event that Licensee elects to terminate or discontinue, or suspend for longer than
twelve (12) months, the Development of any Product which was expressly listed as a Product under Development in any Development Plan provided to Licensor hereunder, including any Clinical Trials involving such Product, and such suspension,
termination or discontinuation is not due to any Technical Failure, Force Majeure or requirement of Applicable Law, as determined by Licensee acting in good faith and as identified in writing to Licensor, then Licensee will be deemed in breach of
its obligation under Section 3.2(a).

(c) Without limiting its other obligations under this Section 3.2, Licensee shall obtain
(i) [***] in the Territory for any Product within [***] after the Effective Date and (ii) an NDA approval in the Territory for any Product within [***]; provided, however, that Licensee shall not be considered to be in breach of any of its

to be the subject of, any such IND and/or NDA.

3.3 Transfer of Know-How. Promptly (but in any event within [***]) following receipt of the
license fee specified in Section 6.1, Licensor shall commence transferring to Licensee copies (in electronic or other mutually agreed upon format) in the English language of all Licensor Data and all other Licensor Know-How in its possession,
and shall use its commercially reasonable efforts to complete all such transfer activities within [***] thereafter. Licensee shall be solely responsible for all costs and expenses incurred for translation of such Licensor Data and other Licensor
Know-How into any other language(s) besides English. In addition, Licensor will provide, at no charge to Licensee, (a) reasonable assistance and cooperation in order to enable Licensee or its designee to implement and utilize such transferred
Licensor Know-How, and (b) provide Licensee with reasonable access to Licensors employees and contractors with appropriate expertise to answer Licensees questions related to such transfer. To the extent Licensor subsequently

Licensor Know-How, including Licensor Data from completed clinical trials, it will promptly inform and make such new Licensor Know-How available to Licensee. Without limiting the foregoing, Licensor shall use Commercially Reasonable Efforts to
require its licensees of the Compound (other than Licensee) to afford Licensor rights in any data that is generated by such licensee in the course of conducting any Phase 3 Clinical Trials in the United States or Europe for the Compound, which

5.2 Supply of Compound and Product. Within [***] following the Effective Date, Licensor will ship to
Licensee [***]. Licensee shall use the Compound provided pursuant to this Section 5.2 for the purposes of conducting pre-clinical studies and research of Products. Licensor will supply the aforementioned Compound to Licensee at no
charge, except that Licensee shall pay the shipping and handling costs associated with the delivery thereof to its designated shipping location. In addition, upon request, Licensor shall work in good faith with Licensee to assist Licensee to obtain
such quantity of the Compound and any Product as is required for the Registrational Clinical Studies to be conducted by Licensee in the Territory pursuant to the Development Plan and such quantity of the Compound and the Product as is requested by
Licensee for the Commercialization of the Product in the Territory. The Parties acknowledge that such assistance may take the form of Licensor facilitating Licensees purchase of the Compound and/ or Product directly from Licensors
then-current supplier(s) of the Compound or such Product, as applicable, or Licensor supplying the relevant quantity of the Compound and/or Product directly to Licensee pursuant to the terms of separate, written supply agreement (s) to be
negotiated by the Parties for such purpose. Licensor will also work to ensure that Licensee is able to purchase the aforementioned supplies of the Compound and/ or Product for use in Clinical Trials and/ or Commercialization, whether purchased
directly from Licensors supplier(s) or from Licensor pursuant to the aforementioned supply agreement(s), at the same transfer price offered to Licensor by the relevant supplier in connection with Licensors own purchases of the Compound
or the same Product from such entity plus a fee, equal to [***], payable to Licensor. Further, if and when Licensor enters into any written commercial supply agreement with a Third Party in regards to any finished Product for purposes of
Licensors commercialization of such Product outside the Territory, at Licensees request, Licensor will use Commercially Reasonable Efforts to require such Third Party supplier to afford Licensee the right to purchase its own requirements
of such Product for Commercialization in the Territory directly from such Third Party (e.g., by submitting purchase orders for such Product directly to such Third Party, subject to the same terms and conditions contained in the written commercial
supply agreement between Licensor and such Third Party).

5.3 Unauthorized Use. Notwithstanding anything to the contrary herein, Licensee shall not
sell or dispose the Compound or any Product outside the Territory nor sell or dispose the Compound or any Product to any Third Party within the Territory other than in connection with the exercise of the rights granted to it by Licensor in Article 2
or the performance of its obligations hereunder, without Licensors prior written consent. For clarity, the sale, distribution (through multiple tiers), transfer or disposition by or on behalf of Licensee or any of its Affiliates or
Sublicensees of any Product which is intended for the treatment of any Therapeutic Indication within the Field of Use to Third Parties located in the Territory shall be considered an exercise of the rights granted to it under Article 2 and thus will
not require the prior written consent of Licensor. Licensee shall not promote, market, offer for sale, sell and distribute the Compound or any Product to any Person outside the Territory or to any Person within the Territory that Licensee knows
is reasonably likely to promote, market, offer for sale, sell or distribute the Compound or Product outside the Territory or assist any Person to do so.

conducted. Any such audit shall be conducted (a) at reasonable frequency, and not more often than [***], (b) at Licensors expense, (c) during the regular business hours of the site being audited, (d) in a manner that
does not unduly disrupt the normal business operations of the audited site, and (e) for the sole purpose of verifying compliance by Licensee (and/or its designated sub-contractor, as applicable) with Applicable Laws in connection with the
Manufacturing of Products. During such visits or audits, Licensor shall have the right to examine all data, documents and records related directly to the Manufacturing of the Product, and all such data, documents and records will be considered
Licensees Confidential Information and will be treated by Licensor as such in accordance with Article 9. In addition, upon reasonable request and with reasonable frequency, Licensee will permit a representative of Licensor to accompany
Licensee on audits it conducts of sites (e.g., hospitals) conducting Clinical Trials on any Product as part of any global Clinical Trial involving such Product; provided, however, that if Licensee is prohibited by Applicable Law or the rules of the
applicable Clinical Trial site from allowing Licensors representative to accompany it during such audit, Licensee will provide Licensor with a copy of any written report summarizing the results of such audit which Licensee creates. All
data, documents, records, information and materials which Licensor views, learns or receives in connection with any such audit or audit report will be considered Licensees Confidential Information and will be treated by Licensor as such in
accordance with Article 9 and may only be used by Licensor if and to the extent necessary to file for Regulatory Approval of the audited Product outside of the Territory.

Calendar Quarter in which each milestone event described in subsection (c) is achieved. After receipt of such notice, Licensor shall submit to Licensee an invoice for the corresponding milestone payment in the applicable
amount. Regardless of when the applicable invoice from Licensor is received, Licensee shall remit each milestone payment associated with the achievement of the milestone events described in subsections (a) and (b) within [***] days
after the achievement thereof. Licensee shall remit the milestone payment associated with the achievement of the milestone events described in subsection (c) to Licensor within [***] days after Licensees receipt of the applicable
invoice from Licensor. Each milestone payment by Licensee that is specified as being payable the first time shall be payable only once, regardless of the number of times that such milestone event is achieved, for the same or different
Products.

contemplated under Section 7.6) from such Third Parties in order to Exploit a Product in the Field in the Territory, Licensee will have the right (at its sole discretion) to negotiate and obtain a license under such Patents (each such Third
Party license is referred to herein as a Third Party License). A Third Party License will be deemed necessary under this Section 6.5(a) if, in the absence of a license under such Third Party Patents, the
Exploitation of the Compound in any Product would, in Licensees good faith assessment, upon advice of counsel, infringe such Third Party Patents. Except as set forth in Section 6.5(b), or to the extent of any Claim for which Licensor
provides indemnification under Section 12.2, or as the Parties may otherwise agree in writing, Licensee shall bear any payments associated with any royalties owed to any Third Party for such Third Party License (collectively, the Third
Party Royalties).

(b) Licensee may credit up to [***] of the amount of any Third Party Royalties paid by Licensee under a Third
Party License deemed necessary pursuant to Section 6.5(a) during any Calendar Quarter against the royalties payable to Licensor under Section 6.3 in respect of the same Calendar Quarter; provided, in no event will the royalties
payable to Licensor for such Calendar Quarter be reduced by more than [***].

6.6 Royalty Statement. Within [***] following the end of each
Calendar Quarter, Licensee shall provide Licensor with a written report containing the following information for the Calendar Quarter, in such reasonable detail as will permit Licensor to calculate and confirm royalty payments hereunder: an
accounting of the number of units and prices for the Products sold, by Product; the amount of gross sales (specified in U.S. dollars) of the Products in the Territory, by Product, including identification of any applicable exchange rate; an itemized

with this Article 6 (including any reductions under Section 6.3(a)(ii) or Section 6.3(b)(ii)); and calculation of the royalty payment due on such Net Sales, as adjusted. At the same time it provides the royalty statement, Licensee
shall pay Licensor the corresponding amount for the applicable Calendar Quarter.

6.7 Corrections.In the event that either Party determines
that the calculation of Net Sales for a Calendar Quarter deviates from the amounts previously reported to Licensor for any reason (such as, on account of additional amounts collected or Product returns), Licensee and Licensor shall reasonably
cooperate to reconcile any such deviations to the extent necessary under applicable legal or financial reporting requirements.

6.8 Payment Terms.
All payments due to Licensor hereunder shall be made in U.S. Dollars by wire transfer of immediately available funds into an account designated by Licensor. If Licensor does not receive payment of any sum due to it on or before the due date,
simple interest shall thereafter accrue on the sum due to until the date of payment at the per annum rate of [***] over the then-current prime rate quoted by Citibank in New York, New York or the maximum rate allowable by Applicable Law, whichever
is lower.

this Agreement shall be the monthly average exchange rate between each currency of origin and U.S. Dollars as reported by the Wall Street Journal East Coast Edition. The monthly average exchange rate shall be the average of (a) the
exchange rate published on the last day of the month; and (b) the exchange rate published on the last day of the preceding month.

6.10 Taxes

(a) Payment of Tax. A Party receiving a payment pursuant to this Article 6 shall pay any and all taxes levied on such
payment. A Party making a payment pursuant to this Article 6 shall make a reasonable effort to obtain the lowest tax rate under Applicable Law for taxes required to be deducted and withheld. If Applicable Law require that taxes be deducted
and withheld from a payment made pursuant to this Article 6, after a Party making a payment makes a reasonable effort to obtain the lowest tax rate, the remitting Party shall: (i) deduct those taxes from the payment; (ii) pay the taxes to
the proper taxing authority; and (iii) send evidence of the obligation together with proof of payment to the other Party within [***] days following that payment.

(b) Tax Residence Certificate. A Party receiving a payment pursuant to this
Article 6 shall provide the remitting Party appropriate certification from relevant revenue authorities that such Party is a tax resident of that jurisdiction, if such receiving Party wishes to claim the benefits of an income tax treaty to which
that jurisdiction is a party. Upon the receipt thereof, any deduction and withholding of taxes shall be made at the appropriate treaty tax rate.

(c) Assessment. Either Party may, at its own expense, protest any assessment, proposed assessment, or other claim by any
Governmental Authority for any additional amount of taxes, interest or penalties or seek a refund of such amounts paid if permitted to do so by Applicable Law. The Parties shall cooperate with each other in any protest by providing records and
such additional information as may reasonably be necessary for a Party to pursue such protest.

6.11 Audit. Licensee shall, and shall cause its
Affiliates who are involved in the conduct of any Development or Commercialization activities in regards to any Product and Sublicensees to, maintain complete and accurate records in accordance with GAAP and in sufficient detail to permit Licensor
to confirm the accuracy of the calculation of royalty and other payments under this Agreement. Upon reasonable prior notice, such records shall be available during regular business hours for a period of [***] from the end of the Calendar Year
to which they pertain for examination at Licensors expense, and not more often than once each Calendar Year, by an independent certified public accountant selected by Licensor and reasonably acceptable to Licensee, for the sole purpose of
verifying the accuracy of the financial reports furnished by Licensee pursuant to this Agreement. Any such auditor shall not disclose any of the records or reports, including any of the information or data contained therein, which are made
available to it by Licensee or any of its Affiliates or Sublicensees, all of which shall be treated and handled as if it were a disclosure to Licensor of Licensees Confidential Information pursuant to Article 9, except to the extent such
disclosure is necessary to verify the accuracy of the financial reports furnished by Licensee or the amount of payments due to Licensor under this Agreement during the prior thirty six (36) months. The auditors report shall be
disclosed simultaneously to Licensee and Licensor. Any amounts shown to be owed to Licensor but unpaid shall be paid within [***] from the accountants report, plus interest (as set forth in Section 6.8) from the original due
date. Any amounts shown to have been overpaid shall be refunded within [***] after the accountants report. Licensor shall bear the full expense of such audit unless such audit discloses an underpayment by Licensee of more than [***]
of the amount due for the audited period, in which case Licensee shall bear the reasonable out-of-pocket cost of such audit.

Parties in the course of conducting any activities under this Agreement, together with all intellectual property rights therein (the Joint Inventions), without any consultation
with or accounting to the other Party, except as set forth below in this Article 7 with respect to protection and enforcement of such Joint Inventions and except, with respect to Licensee, its obligation to pay royalties to Licensor pursuant to
Article 6 for any Products covered by Valid Claims of any Joint Patent which is exclusively licensed to it under Section 2.1. Employees or agents of Licensor and Licensee that are named as inventors on Joint Patents shall assign their interest
in such Patents to the corresponding Party.

7.2 Disclosure of Inventions.

(a) Joint Inventions.Each Party shall promptly disclose to the other Party any invention disclosures, or other similar documents,
submitted to it by its employees, agents or independent contractors describing inventions made during the Term that such Party believes are patentable Joint Inventions.

(b) Licensor Sole Inventions.Licensor shall inform Licensee of any Sole Invention discovered or generated during the Term by its
employees, agents or independent contractors, and all Information relating to such inventions to the extent necessary for the use of such Invention in the Exploitation of any Product (including any Evogliptin Combination Product) in the Field and,
to the extent patentable, for the preparation, filing and maintenance of any Patent with respect to such invention in accordance with Section 7.3. For avoidance of doubt, all Patents covering any such Sole Invention shall be deemed to be
Licensor Patents, and all Information related to any such Sole Invention shall be deemed to be Licensor Know-How (and Licensor Data, if applicable), under this Agreement.

agents or independent contractors during the Term that (i) covers or claims any improvement to the Compound or any use of only the Compound in any Therapeutic Indication and that (ii) does not cover or claim the Compound (or any
improvement thereto or use thereof) in combination with any other API (a Licensee Compound Invention). For avoidance of doubt, under this Agreement, Licensor obtains no right, title, license, option or other interest in or to
any Licensee Sole Invention, except as expressly provided under Section 10.7.

7.3 Prosecution of Patents.

(a) Joint Inventions. The Parties will confer with each other as to the desirability of filing Patent applications on, and/or taking
such other steps as may be necessary to acquire and maintain Patent rights in the Joint Inventions, and the Parties shall share equally the expenses of any such filings and other steps and mutually agree upon an outside counsel firm to handle such
filings. In the event one Party notifies the other Party in writing that it does not wish to: (i) file for a Patent on the Joint Invention; (ii) file or maintain any Patent application or Patent previously filed or issued outside of

the other Party will have the right to do so at its own expense. At the re quest of the Party permitted under the prior sentence to file for a Patent, foreign file or maintain a Patent or
Patent application outside of the Territory or take any such other steps outside the Territory with respect to the Joint Invention on its own, the Party not filing or maintaining such Patent applications or Patents or taking such other steps (such
Party, the Non-Participating Party) shall assign its entire interest in such Patent or Patent application to the other Party, subject to retaining a non-exclusive, unrestricted, perpetual, irrevocable, paid-up, royalty-free
license (with an unrestricted right to sublicense) under the Patents (including any patents which issue from such applications) to make, have made, use, offer for sale, sell and import any products using the Joint Inventions outside the Territory,
all without further consent of the other Party and without accounting to the other Party. From and after the date that any such assignment occurs, the Patents or Patent applications assigned by the Non-Participating Party shall cease to be
considered a Joint Patent for all purposes during the Term of this Agreement and the Agreement will be deemed to be automatically amended, without any further action required of the Parties, to reflect the change.

(b) Licensor Patents. Beginning on Effective Date, and except as otherwise provided in this Section 7.3(a), Licensee shall
have the sole right and authority during the Term to prepare, file, prosecute and maintain the Licensor Patents in the Territory. Licensee shall bear all expenses of preparation, filing, prosecution and maintenance of Licensor Patents in the
Territory. Licensee shall provide Licensor a reasonable opportunity to review and comment on material communications from any patent authority regarding the Licensor Patents and drafts of any material filings or responses to be made to such patent
authorities in advance of submitting such filings or responses. Licensee shall consider Licensors comments regarding such communications and drafts in good faith. If Licensee determines in its sole discretion to abandon or not
maintain any Licensor Patent(s) that is being prosecuted or maintained by Licensee in the Territory, then Licensee shall provide Licensor with written notice of such determination within a period of time reasonably necessary to allow Licensor to
determine, in its sole discretion, its interest in such Licensor Patent(s) (which notice by Licensee shall be given no later than [***] prior to the final deadline for any pending action or response that may be due with respect to such
Licensors Patent(s) with the applicable patent authority) in the Territory. Thereafter, Licensor has the sole right and authority to prepare, file, prosecute and maintain the applicable Licensor Patents in the Territory, Licensor shall provide
Licensee a reasonable opportunity to review and comment on material communications from any patent authority regarding such Licensor Patents and drafts of any material filings or responses to be made to such patent authorities in advance of
submitting such filings or responses. Licensor shall consider Licensees comments regarding such communications and drafts in good faith. Licensee shall reimburse Licensor its reasonable, documented, out-of-pocket expenses incurred by
it during such period in the filing, prosecution and maintenance of the Licensor Patents, provided Licensee has agreed in advance to such filing generally and to such filing in the Territory. For the purposes of this Section 7.3(b),
Licensor Patents shall be deemed to include all Joint Patents in the Territory.

(ii) Licensee shall notify Licensor of its election to take any action under Section 7.
5 (b)(i) within [***] before any time limit set forth in an Applicable Law. In the event Licensee does not give such notice in a timely manner or notifies Licensor that it will not be taking action, Licensor shall have the right, but not the
obligation, to commence a suit or take action to enforce the applicable Licensor Patent or Joint Patent against such Third Party, at its own expense. If one Party elects to bring suit or take action against the Product Infringement, then the
other Party shall have the right, prior to commencement of the trial, suit or action, to join any such suit or action.

(iii) The other
Party shall provide to the enforcing Party reasonable assistance in such enforcement, at the 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 shall keep the other Party regularly informed of the status and progress of such enforcement efforts, and shall reasonably consider the other Partys comments on any such efforts.

(iv) The enforcing Party shall be solely responsible for all costs and expenses arising from a suit or action against a Product Infringement;
provided, the enforcing Party shall not be responsible for the other Partys internal expenses (e.g., FTEs) incurred as a result of the other Partys cooperation with the enforcement action as provided in Section 7.5(b)(iii). The
Party not bringing an action with respect to Product Infringement in the Territory under this Section 7.5(b) shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense, but such Party shall
at all times cooperate fully with the Party bringing such action.

or action that it brought under this Section 7.5 with respect to any Licensor Patent or Joint Patent without the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed.

(d) Allocation of Proceeds. If either Party recovers monetary damages from any Third Party under Section 7.5(b) or
Section 7.5(c), or any royalties from a license agreement with a Third Party related to any alleged Product Infringement, whether such damages or royalties result from the infringement of Licensor Patents or Joint Patents, such recovery shall
be allocated first to the reimbursement of any expenses incurred by the Parties in such litigation, action or license, and any remaining amounts shall be split as follows: (i) if Licensee is the enforcing party, then such amounts shall be
retained by Licensee and treated as Net Sales for purposes of the royalties due to Licensor under this Agreement; or (ii) if Licensor is the enforcing party, then such amounts shall be retained by Licensor.

any costs for policing any Patent on any Joint Intellectual Property or for enforcing or defending any Patent covering any Joint Intellectual Property (or any part thereof) against any Third Party outside the Territory. Notwithstanding the
foregoing, a Party will notify the other Party in writing prior to commencing any enforcement action of intellectual property rights in Joint Inventions against any Third Party outside the Territory during the Term or inside the Territory after the
Term. Any enforcement or defense of any intellectual property rights involving Joint Intellectual Property that is mutually undertaken by both Parties pursuant to this Section 7.5(e) requires separate agreement between the Parties. If
one of the Parties provides the other Party written notice of its decision not to participate in an enforcement action of intellectual property rights in any Joint Intellectual Property and the other proceeds with such action, the proceeding Party
has no obligation to account to the non-participating Party for any amounts collected.

7.6 Infringement of Third Party Rights.

(a) Notice. If any Product used or sold by Licensee, or its Affiliates or Sublicensees, becomes the subject of a claim or
assertion of infringement of a Third Partys Patent granted in the Territory, the Party first having notice of the claim or assertion shall promptly notify the other Party, the Parties shall agree on and enter into an identity of interest
agreement wherein such Parties agree to their shared, mutual interest in the outcome of such potential dispute, and thereafter, the Parties shall promptly meet to consider the claim or assertion and the appropriate course of action.

(b) Defense. Licensee shall have the first right, but not the obligation, to defend any such Third Party claim or assertion of
infringement described in Section 7.6(a) above, at Licensees expense. If Licensee does not commence any action to defend such claim within [***] after it receives notice thereof (or within [***] after it should have given notice
thereof to Licensor as required by Section 7.6(a)), then to the extent allowed by Applicable Law, Licensor shall have the right, but not the obligation, to control the defense of such claim by counsel of its choice, at Licensors
expense. The non-defending Party shall reasonably cooperate with the Party conducting the defense of the claim or assertion, including if required to conduct such defense, furnishing a power of attorney. If the defending Party recovers
monetary damages from any such Third Party asserting such a claim of infringement as a result of counter claims brought by such defending Party based on any Licensor Patent or Joint Patent, or any royalties from a license agreement with such Third
Party, such recovery shall be allocated first to the reimbursement of any expenses incurred by the defending Party in such litigation, action or license, and any remaining amounts shall be split as follows: (i) if such suit or action is
defended by Licensee, such amounts shall be retained by Licensee and treated as Net Sales for purposes of the royalties due to Licensor under this Agreement; or (ii) if such suit or action was defended by Licensor, such amounts shall be
retained by Licensor.

(c) Settlement; Licenses. Neither Party shall enter into any settlement of any
claim described in this Section 7. 6 that is inconsistent with this Agreement or that affects the other Partys rights or interests without the other Partys written consent, which consent shall not be unreasonably withheld,
conditioned or delayed. Each Party shall have the right to decline to defend or to tender defense of any such claim to the other Party upon reasonable notice, including if the other Party fails to agree to a settlement that such Party proposes.

7.7 Patent Oppositions and Other Proceedings.

(a) Third-Party Patent Rights. If, during the Term, either Party desires to bring an opposition, action for declaratory judgment,
nullity action, interference, declaration for non-infringement, reexamination or other attack upon the validity, title or enforceability of a Patent owned or controlled by a Third Party and having one or more claims that cover (or purport to cover)
the Product, or the use, sale, offer for sale or importation of the Product (except insofar as such action is a counterclaim to or defense of, or accompanies a defense of, a Third Partys claim or assertion of infringement under
Section 7.6, in which case the provisions of Section 7.6 shall govern), such Party shall so notify the other Party and the Parties shall promptly confer to determine whether to bring such action or the manner in which to settle such
action. Licensee shall have the exclusive right, but not the obligation, to bring at its own expense and in its sole control such action in the Territory. If Licensee does not bring such an action in the Territory, within [***] of
notification thereof pursuant to this Section 7.7(a) (or earlier, if required by the nature of the proceeding), then Licensor shall have the right, but not the obligation, to bring such action, at Licensors sole expense. The Party
not bringing an action under this Section 7.7(a) shall be entitled to separate representation in such proceeding by counsel of its own choice and at its own expense, and shall cooperate fully with the Party bringing such action.

(b) Parties Patent Rights. If, during the Term, any Licensor Patent or Joint Patent becomes the subject of any proceeding
commenced by a Third Party within the Territory in connection with an opposition, reexamination request, action for declaratory judgment, nullity action, interference or other attack upon the validity, title or enforceability thereof (except insofar
as such action is a counterclaim to or defense of, or accompanies a defense of, an action for infringement against a Third Party under Section 7.5, in which case the provisions of Section 7.5 shall govern), then the Party responsible for
filing, preparing, prosecuting and maintaining such Patent as set forth in Section 7.3 hereof, shall control such defense at its own expense. The controlling Party shall permit the non-controlling Party to participate in the proceeding to
the extent permissible under Applicable Law, and to be represented by its own counsel in such proceeding, at the non-controlling Partys expense. If either Party decides that it does not wish to defend against such action, then the other
Party shall have a backup right to assume defense of such Third-Party action at its own expense. Any awards or amounts received in defending any such Third-Party action shall be allocated between the Parties as provided in Section 7.5(d).

Law.

Information as required under this Article 9; or

(g) in the case of Licensor only, to Takeda as necessary for Licensor to comply with its
disclosure and reporting obligations under the Takeda License Agreement.

If and whenever any Confidential Information is disclosed in accordance with

9.8 Equitable Relief. Given the nature of the Confidential Information and the competitive damage that
could result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages may not be a sufficient remedy for any breach of this Article 9. In addition to all

the Breaching Party from the Non-Breaching Party (the Cure Period). The written notice describing the alleged material breach shall provide sufficient detail to put the Breaching Party on notice of such material breach. Any
termination of this Agreement pursuant to this Section 10.2(a) shall become effective at the end of the Cure Period, unless the Breaching Party has cured any such material breach prior to the expiration of such Cure Period, or unless such
allegedly breaching Party disputes such breach pursuant to Section 10.2(b) in a timely manner. The right of either Party to terminate this Agreement as provided in this Section 10.2(a) shall not be affected in any way by such
Partys waiver of or failure to take action with respect to any previous breach under this Agreement.

and in good faith disagree as to whether there has been a material breach, including whether such breach was material, the Party that disputes whether there has been a material breach may contest the allegation in accordance with Article

10.3 Termination by Licensee.Licensee shall have the unilateral right to terminate this Agreement (in whole or in part) at any time, for any
reason or no reason, upon at least [***] prior written notice to Licensor. Licensees termination notice shall specify whether it applies with respect to the entire Agreement or only certain Patents.

10.4 Termination for Patent Challenge. Licensor may terminate this entire Agreement at any time upon providing written notice to Licensee, if
Licensee, or any of its Affiliates, or its or their Sublicensees (each, a Challenging Party), directly or indirectly (through assistance granted to a Third Party), commences any interference or opposition proceeding, challenges
the validity or enforceability of, or opposes any extension of or the grant of a supplementary protection certificate with respect to (a Patent Challenge) any Licensor Patent or any other Patent owned or controlled by Licensor
that claims or discloses the composition of matter or the method of making or using the Compound or any Product, anywhere in the Territory. However, Licensors right to terminate this Agreement under this Section 10.4 shall not apply

(a)
Either Party may terminate this Agreement in its entirety upon providing written notice to the other Party on or after the time that such other Party makes a general assignment for the benefit of creditors, files an insolvency petition in

its insolvency, bankruptcy, reorganization, adjustment of debt, dissolution, liquidation or any other similar proceeding for the release of financially distressed debtors, or becomes a party to any proceeding or action of the type described above,
and such proceeding or action remains un-dismissed or un-stayed for a period of more than [***].

licenses of rights to intellectual property (as defined under Section 365(n) of the Bankruptcy Laws in the United States). If a case is commenced during the Term by or against a Party under Bankruptcy

Laws then, unless and until this Agreement is rejected as provided pursuant to such Bankruptcy Laws, such Party (in any capacity, including debtor-in-possession) and its successors and assigns
(including a trustee) shall perform all of the obligations in accordance with this Agreement. If a case is commenced during the Term by or against a Party under the Bankruptcy Laws, and if this Agreement is rejected as provided for under the
Bankruptcy Laws and the non-bankrupt Party elects to retain its rights hereunder as provided for under the Bankruptcy Laws, then the Party subject to such case under the Bankruptcy Laws (in any capacity, including debtor-in-possession) and its
successors and assigns (including a trustee) shall provide to the non-bankrupt Party copies of all Patents and Information necessary for the non-bankrupt Party to prosecute, maintain and enjoy its rights under the terms of this Agreement. All
rights, powers and remedies of the non-bankrupt Party as provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including the Bankruptcy Laws) in
the event of the commencement of a case by or against a Party under the Bankruptcy Laws. In particular, it is the intention and understanding of the Parties to this Agreement that the rights granted to the Parties under this Section 10.5
are essential to the Parties respective businesses and the Parties acknowledge that damages are not an adequate remedy.

remedies. Upon the termination of this Agreement:

hereunder and the license granted to Licensor by Licensee under Section 2.2 shall remain in effect (except in the event of a termination of this Agreement by Licensee pursuant to Section 10.2 or Section 10.5, in which case such
license shall immediately cease to be of any further force or effect upon the effective date of termination of this Agreement);

(d)
Licensee shall in good faith coordinate the wind-down of Licensees efforts under this Agreement, and Licensee, as soon as reasonably practical after the effective date of such termination, shall provide to Licensor, as applicable and to the
extent permitted under any applicable Third Party contract (i) any Information, including copies of all data and results generated from any Clinical Trial, and the like developed by or for the benefit of Licensee relating to the Products

such material Information and documents. At Licensors request, Licensee shall assign to Licensor any and all agreements to which Licensee (or its Affiliate) and a Third Party are parties, and that govern the Development, Commercialization and
Manufacturing activities conducted in connection with the Products (excluding any Evogliptin Combination Product) prior to such termination, or if such assignment is not permitted under the relevant agreement: (A) grant to Licensor other rights
to provide to Licensor the benefit of such non-assignable agreement, at Licensors expense, to the extent permitted under the terms of such non-assignable agreement; or (B) to the extent not permitted under the terms of such non-assignable
agreement, the Parties shall discuss in good faith an alternative solution to enable Licensor to receive, at Licensors expense, the benefit of the terms of such non-assignable agreement. In addition to the actions contemplated in this
Section 10. 6 (d), Licensee shall take such other actions and execute such other instruments, assignments and documents as may be necessary to effect the transfer of rights to the Product hereunder to Licensor;

(e) Subject to the payment of all amounts required under Section 10.6(b) above, Licensee shall have the right to sell or otherwise
dispose of any inventory of Products on hand at the time of such termination or in the process of Manufacturing; provided, however, Licensee shall, at Licensors election, either destroy or return to Licensor any Product that has not been sold
or used within [***] following such termination;

(f) Licensee shall transfer and assign to Licensor any and all Regulatory Materials and
Regulatory Approvals directly and solely related to any Product (excluding any Evogliptin Combination Product and any other Combination Product) in the Territory, including any Regulatory Materials previously assigned by Licensor to Licensee and
Product INDs and, upon Licensors request, shall make available to Licensor any other relevant information reasonably related to such Regulatory Materials and Regulatory Approvals;

(g) Licensor shall have the right to assume all prosecution, maintenance, and enforcement activities under Article 7 with respect to Licensor
Patents in the Territory. Licensee shall cooperate with Licensor and provide Licensor with reasonable assistance and cooperation with the prosecution, maintenance, and enforcement activities with respect to the Licensor Patents; and

(h) The provisions in Section 2.3(c) shall apply in the case of a termination of this Agreement by Licensor pursuant to Sections 10.2,
10.3, 10.4 or 10.5.

10.7 Licensee Compound Invention; Joint Invention. Upon any expiration or termination of this Agreement, Licensee agrees
to assign and does hereby assign to Licensor all of Licensees rights, title and interests (including without limitation, Patent rights) in and to all Licensee Compound Inventions, if any, without representation or warranty of any
kind. Licensee agrees to reasonably cooperate with Licensor in transferring tangible Information related to Licensee Compound Inventions to Licensor. Automatically upon any expiration or termination of this Agreement, without any further action
required by the Parties, each Party (the Licensing Party)

10.8 Remedies. Notwithstanding anything to the contrary in this Agreement, except as otherwise set forth in this Agreement, termination or

ARTICLE 12  INDEMNIFICATION

12.1 Indemnification by Licensee. Licensee hereby agrees to defend, indemnify and hold harmless Licensor and its Affiliates, and each of their
respective directors, officers, employees, agents and representatives (each, a Licensor Indemnitee) from and against any and all claims, suits, actions, demands, liabilities, expenses and/or loss, including reasonable legal
expenses and attorneys fees (collectively, the Losses), to which any Licensor Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third Party (each, a Claim)
to the extent such Losses arise directly or indirectly out of: (a) the practice by Licensee or its Affiliate of any license granted to it under Article 2; (b) the use, handling, storage, sale or other disposition of the Compound or
Products by Licensee, or its Affiliate or Sublicensee, including any use of the Compound or Products for Development, Manufacture and Commercialization; (c) the breach by Licensee of any warranty, representation, covenant or agreement made by
Licensee in this Agreement; (d) the negligence, gross negligence or willful misconduct (including to the extent such negligence, gross negligence or willful misconduct gives rise to Product Liabilities under any legal theory) of Licensee, or
its Affiliate or Sublicensee, or any officer, director, employee, agent or representative thereof; except, with respect to each of subsections (a) through (d) above, to the extent such Losses arise directly or indirectly from (i) the
negligence, gross negligence or willful misconduct of any Licensor Indemnitee, (ii) the direct supply by Licensor (pursuant to the supply agreement(s), if any, between the Parties contemplated in Section 5.2) of the Compound or Product
giving rise to the Claim or (iii) the breach by Licensor of any warranty, representation, covenant or agreement made by Licensor in this Agreement.

12.2 Indemnification by Licensor. Licensor hereby agrees to defend, indemnify and hold harmless Licensee and its Affiliates and each of their
respective directors, officers, employees, agents and representatives (each, an Licensee Indemnitee) from and against any and all Losses to which any Licensee Indemnitee may become subject as a result of any Claim to the extent
such Losses arise directly or indirectly out of: (a) the breach by Licensor of any warranty, representation, covenant or agreement made by Licensor in this Agreement; or (b) the negligence or willful misconduct of Licensor or any of its
Affiliates or other licensees, or any officer, director, employee, agent or representative thereof; except, with respect to each of subsections (a) and (b) above, to the extent such Losses arise directly or indirectly from the
(i) negligence, gross negligence or willful misconduct of any Licensee Indemnitee or (ii) the breach by Licensee of any warranty, representation, covenant or agreement made by Licensee in this Agreement.

12.3 Indemnification Procedures.

(a)
Notice.Promptly after any Indemnitee receives notice of a pending or threatened Claim, such Indemnitee shall give written notice of the Claim to the Party from whom the Indemnitee is entitled to receive indemnification pursuant to
Sections 12.1 or 12.2, as applicable (the Indemnifying Party). However, an Indemnitees delay in providing or failure to provide such notice shall not relieve the Indemnifying Party of its indemnification
obligations, except to the extent it can demonstrate prejudice due to the delay or lack of notice.

(b) Defense. Upon receipt of
notice under Section 12.3(a) from the Indemnitee, the Indemnifying Party shall have the duty to either compromise or defend, at its own expense and

by counsel (reasonably satisfactory to Indemnitee), such Claim. The Indemnifying Party shall promptly (and in any event not more than [***] after receipt of the Indemnitees original
notice) notify the Indemnitee in writing that it acknowledges its obligation to indemnify the Indemnitee with respect to the Claim pursuant to this Article 12 and of its intention either to compromise or defend such Claim. Once the Indemnifying
Party gives such notice to the Indemnitee, the Indemnifying Party is not liable to the Indemnitee for the fees of other counsel or any other expenses subsequently incurred by the Indemnitee in connection with such defense, other than the
Indemnitees reasonable expenses of investigation and cooperation. However, the Indemnitee shall have the right to employ separate counsel and to control the defense of a Claim at its own expense.

(c) Cooperation. The Indemnitee shall cooperate fully with the Indemnifying Party and its legal representatives in the investigation
and defense of any Claim. The Indemnifying Party shall keep the Indemnitee informed on a reasonable and timely basis as to the status of such Claim (to the extent the Indemnitee is not participating in the defense of such Claim) and conduct the
defense of such Claim in a prudent manner.

(d) Settlement. If an Indemnifying Party assumes the defense of a Claim, no compromise
or settlement of such Claim may be effected by the Indemnifying Party without the Indemnitees written consent (which consent shall not be unreasonably withheld, conditioned or delayed), unless: (i) there is no finding or admission of any
violation of law or any violation of the rights of any person and no effect on any other claims that may be made against the Indemnitee; (ii) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party; and
(iii) the Indemnitees rights under this Agreement are not adversely affected. If the Indemnifying Party fails to assume defense of a Claim within a reasonable time, the Indemnitee may settle such Claim on such terms as it deems
appropriate with the consent of the Indemnifying Party (which consent shall not be unreasonably withheld, conditioned or delayed), and the Indemnifying Party shall be obligated to indemnify the Indemnitee for such settlement as provided in this
Article 12.

12.4 Limitation of Liability. EXCEPT FOR A PARTYS OBLIGATIONS SET FORTH IN THIS ARTICLE 12, AND ANY BREACH OF ARTICLE 9
(CONFIDENTIALITY), IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY (OR THE OTHER PARTYS AFFILIATES OR SUBLICENSEES) IN CONNECTION WITH THIS AGREEMENT FOR LOST REVENUE, LOST PROFITS, LOST SAVINGS, LOSS OF USE, DAMAGE TO GOODWILL, OR
ANY CONSEQUENTIAL, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE OR INDIRECT DAMAGES UNDER ANY THEORY, INCLUDING CONTRACT, NEGLIGENCE, OR STRICT LIABILITY, EVEN IF THAT PARTY HAS BEEN PLACED ON NOTICE OF THE POSSIBILITY OF SUCH DAMAGES.

13.2 Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the
extent that such performance is prevented by Force Majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting Force Majeure continues
and the nonperforming Party takes reasonable efforts to remove the condition. Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a Force Majeure affecting such Party. If a Force
Majeure persists for more than [***], then the Parties shall discuss in good faith the modification of the Parties obligations under this Agreement in order to mitigate the delays caused by such Force Majeure.

13.3 Assignment. Each Party may assign or transfer this Agreement or any rights or obligations hereunder to any of its Affiliate, without the other
Partys prior written consent. Each Party may assign or transfer this Agreement to a successor to all or substantially all of its business or assets that relate to this Agreement (whether by sale of stock or assets, merger, consolidation
or otherwise) with prior written notice to, but without the consent of, the other Party. Any other assignment or transfer shall require the prior written consent of the other Party. Any assignee permitted hereunder shall, in writing to the
other Party, expressly assume performance of all of the assigning Partys rights and/or obligations. 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 13.3 shall be null, void and of no legal effect.

13.4 Severability. If any one or more of the
provisions of this Agreement is held to be invalid or unenforceable by 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.

13.5 Waiver and Non-Exclusion of Remedies. Any term or condition of this Agreement may be waived at
any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. The waiver by either Party
hereto of any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by such other Party whether of a similar nature or
otherwise. The rights and remedies provided herein are cumulative and do not exclude any other right or remedy provided by Applicable Law or otherwise available except as expressly set forth herein.

13.6 Further Assurance. Each Party shall duly execute and deliver, or cause to be duly executed and delivered, such further instruments and do and
cause to be done such further acts and things, including the filing of such assignments, agreements, documents, and instruments, as may be necessary or as the other Party may reasonably request in connection with this Agreement or to carry out more
effectively the provisions and purposes hereof.

13.7 Relationship of the Parties. It is expressly agreed that Licensor, on the one hand, and
Licensee, on the other hand, shall be independent contractors and that the relationship between the two Parties shall not constitute a partnership, joint venture or agency. Neither Licensor nor Licensee shall have the authority to make any
statements, representations or commitments of any kind, or to take any action which shall be binding on the other, without the prior written consent of the other Party to do so. All persons employed by a Party shall be employees of that Party
and not of the other Party and all expenses and obligations incurred by reason of such employment shall be for the account and expense of such Party.

13.8 Counterparts.This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument. This Agreement may be executed by facsimile, .pdf or other electronically transmitted signatures and such signatures shall be deemed to bind each Party hereto as if they were the
original signatures.

13.9 Construction. Except where the context otherwise requires, wherever used, the singular shall include the plural, the
plural the singular, and the use of any gender shall be applicable to all genders. Whenever this Agreement refers to a number of days, such number refers to calendar days. The captions of this Agreement are for the convenience of reference
only and in no way define, describe, extend, or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement. The terms including, include, or includes as used herein
shall mean including, but not limited to, and shall not limit the generality of any description preceding such term. The language of this Agreement shall be deemed to be the language mutually chosen by the Parties and no rule of
strict construction shall be applied against either Party hereto. Each Party represents that it has been represented by legal counsel in connection with this Agreement and acknowledges that it has participated in the drafting hereof. In
interpreting and applying the terms and provisions of this Agreement, the Parties agree that no presumption will apply against the Party which drafted such terms and provision.

the interpretation of, and any dispute regarding, the terms of this Agreement. This Agreement and all disputes arising out of or related to this Agreement or any breach hereof shall be governed by and construed under the laws of the State of

EXAMPLE OF ROYALTY CALCULATIONS

1.
Tobira Royalty - Effect of Combination Product Sales on Calculation of Net Sales for Purpose of Calculating Tobira Royalty

In order to determine the
Net Sales of Products in the Territory for the purpose of calculating the Tobira Royalty, the Net Sales number must be adjusted to account for Combination Products. For each Product, this adjustment is accomplished by multiplying the Net Sales for
that Product by the quotient of 1 divided by the number of APIs in the Product. The following table provides non-limiting examples of how the sales of Combination Products effects the Net Sales amount used to calculate the Tobira Royalty:



|                                                         |  |                                                    |  |

2. Takeda Royalty  Determining Royalty Rate for Takeda Royalty

The royalty rate used to determine the amount of the Takeda Royalty payable by Licensee to Licensor pursuant to 6.3(b) of the Agreement will be calculated by
Licensor based on the global total annual net sales of products that contain the Compound and for which Licensor is obligated to pay royalties to Takeda under the Takeda License Agreement, including the Products (collectively, Royalty
Bearing CVC Products). Licensor is required to pay Takeda a running royalty for global sales of Royalty Bearing CVC Products based on the following tiers:



| |  |  | [***] royalty on the portion of global net sales of the Royalty Bearing CVC Products up to and including [***]

At least
[***] following the end of each Calendar Quarter during the Term of the Agreement, Licensor will estimate its global net sales of Royalty Bearing CVC Products for the then-current Calendar Year and its associated royalty payment obligation to
Takeda. Based on this estimate, Licensor will calculate the royalty rate for Licensees Takeda Royalty for that Calendar Quarter. The royalty rate for the Takeda Royalty will be a blend of the rates set forth above that are applicable to
Licensors estimate of global net sales of Royalty Bearing CVC Products for that Calendar Year. Licensee will then multiply that blended royalty rate by its Net Sales for Products for that Calendar Quarter in order to calculate the Takeda
Royalty.

To determine the blended royalty rate for Licensees Takeda Royalty, Licensor will divide its total estimated royalty
payment obligation to Takeda for Calendar Year 2020 (in this example, [***] M) by the estimated Calendar Year 2020 global net sales of Royalty Bearing CVC Products (in this example[***]). The resulting blended royalty rate is [***]. Licensee would
then apply this global blended rate to its Net Sales of the Products for Q1 of Calendar Year 2020 to calculate the Takeda Royalty due Licensor for Q1 of Calendar Year 2020.

At the end of each Calendar Quarter, Licensor will re-calculate the blended royalty rate for Licensees Takeda Royalty. Within [***] following the end of
each Calendar Year, Licensor shall do a true up of Licensees Takeda Royalty for that Calendar Year to account for actual (as opposed to estimated) global net sales of Royalty Bearing CVC Products and will provide a

written report summarizing the true-up calculation (each such report, an Annual True-Up Report). If the Annual True Up Report shows that Licensees Takeda Royalty payments
over the course of the prior Calendar Year were lower than they should have been due to a discrepancy between Licensors estimated sales and actual sales of Royalty Bearing CVC Products, then Licensee shall pay the additional amount required to
satisfy its actual Takeda Royalty obligations within [***] after Licensees receipt of such Annual True-Up Report. If the Annual True Up Report shows that Licensees Takeda Royalty payments over the course of the prior Calendar Year were
higher than they should have been due to a discrepancy between Licensors estimated sales and actual sales of Royalty Bearing CVC Products, then Licensor shall apply the excess Takeda Royalty payments as a credit towards Licensees Takeda
Royalty obligations for the following Calendar Year. If the overage occurs during the last Calendar Year (or portion thereof) in which the Agreement expires, Licensor shall reimburse Licensee for any such excess Takeda Royalty payments applicable to
such Calendar Year within [***] after the end of such Calendar Year.

3. Takeda Royalty - Effect of Combination Product Sales on Net Sales for Purpose
of Calculating Takeda Royalty

In order to determine the Net Sales of Combination Products in the Territory for the purpose of determining the Takeda
Royalty, the Net Sales number associated with any Combination Product must be adjusted downward so as to only account for the portion of the Net Sales of the Combination Product that are attributable to the Compound. This downward adjustment is
calculated using the following formula for each Combination Product: Net Sales in Territory x A/A+B where,

A = Average Price for the
Monotherapy Product in Territory

B = Average Price of the products containing each of the other APIs as their sole therapeutically active
ingredients in the Combination Product and/or the separate components co-packaged with the Product sold separately in the same formulation/dosage and having the same approved Therapeutic Indication.

As used in the above equation, Average Price means the average selling price weighted by [***] for the relevant product in that Calendar
Quarter. For clarity, the denominator in the equation will include the Average Price in the Territory for each monotherapy product containing one of the APIs used in the Combination Product. If A or B cannot be determined because values for the
Product or other product containing the other APIs other than the Compound sold alone are not available in the Territory, then the non-available A or B, as the case may be, shall be the average price weighted by the [***] in the Calendar Quarter for
which royalties are being calculated hereunder at which the Product or the other APIs are sold alone in

the dosage included in the Combination Product in the United States. In the event that no Products or other APIs are sold alone in the Territory or in the United States, the Parties shall
negotiate in good faith an allocation of the fair market value of the Product in the Combination Product.

Example:

If a Combination Product comprised of only Evogliptin and the Compound generated annual Net Sales in the Territory equal to [***], and the Average Price of the
Evogliptin monotherapy was [***] and the Average Price of the Monotherapy Product was [***], then the adjusted Net Sales amount used to calculate the Takeda Royalty would be [***].

FORM OF PRESS RELEASE

Tobira Therapeutics and Dong-A ST Enter Into License Agreements for Evogliptin and Cenicriviroc

Tobira gains rights to second asset for NASH in North America, Europe & Australia

First combination study with cenicriviroc to begin late 2016

Conference Call Scheduled for today at 8:30 a.m. ET

South San Francisco, Calif., and Seoul, Republic of Korea, April 11, 2016Tobira Therapeutics, Inc. (NASDAQ: TBRA) and Dong-A ST Co., Ltd.
(170900: Korea SE), today announced that the companies have entered into two separate licensing agreements. Tobira has acquired exclusive rights to develop and market evogliptin in combination with cenicriviroc (CVC) and as a single agent in the
United States, Canada, Europe and Australia for all therapeutic indications. Dong-A has received an exclusive license to develop and market CVC, as both a single agent and in combination with evogliptin in the Republic of Korea for all therapeutic
indications. Both companies plan to initiate development programs for the combination of the two agents for the treatment of patients with non-alcoholic steatohepatitis (NASH) and also plan to collaborate on a global Phase 3 program for CVC single
agent for NASH.

Under the terms of the agreement, Dong-A received an upfront cash payment of $1.5 million and is eligible to receive up to an additional
$25 million in payments linked to the achievement of Phase 3 completion and approval milestones for the first indication and up to an additional $10 million for additional indications. Dong-A may receive up to an additional $35 million for
commercial milestones. Tobira received an upfront cash payment of $0.5 million and is eligible to receive up to an additional $2.5 million in payments linked to the achievement of similar milestones per indication in the Republic of Korea. In
addition, each party will receive tiered royalty payments based on net sales. Each company is responsible for its own development costs incurred within its respective territory.

This relationship with Dong-A is an important step toward our goal of developing much needed combination therapies for the millions of patients
suffering from NASH and to become the preferred partner for companies seeking to develop NASH therapies, said Laurent Fischer, M.D., chief executive officer of Tobira. While incretin therapies are already standard of care for diabetes,
they also have the potential to impact the metabolic issues that play a role in NASH disease progression. Evogliptin is a potent DPP-4 inhibitor administered as a small 5mg once-daily tablet and has demonstrated compelling preclinical and clinical
activity. It complements the anti-inflammatory and anti-fibrotic effects of cenicriviroc and has the potential to be combined in a fixed dose combination tablet.

Evogliptin (Suganon®) was launched in the Republic
of Korea in March of this year for blood glucose control in patients with type 2 diabetes mellitus. There is a substantial amount of data suggesting that the incretin/GLP-1 pathways targeted by evogliptin are implicated in the progression of
non-alcoholic fatty liver disease (NAFLD) and NASH. The combination of agents is intended to simultaneously address the metabolic pathogenesis of NASH and the inflammation and fibrosis that cause liver damage and often lead to cirrhosis, liver
cancer or liver failure. The ultimate goal is to achieve greater improvement of liver-related outcomes.

We are pleased to be working with Tobira to
further the development of evogliptin in combination with CVC, said Soo-Hyoung Kang, president & CEO of Dong-A ST Co., Ltd. Their focus and experience in liver disease will allow us to explore the potential of our drugs to help
patients suffering from non-alcoholic steatohepatitis. NASH is an epidemic that affects millions of people globally, including many people in South Korea, and we are excited to be combining two potentially best-in-class products to develop a much
needed therapy for these patients.

Tobira plans to conduct preclinical toxicology and pharmacokinetics studies with evogliptin required prior to
initiating a Phase 1 study of the CVC-evogliptin combination in late 2016.

Conference Call Information

Tobira will host a conference call today to review details of the agreement beginning at 5:30 a.m. Pacific Time /8:30 a.m. Eastern Time. Analysts and investors
can participate in the conference call by dialing +1 (855) 638-8858 for domestic callers and +1 (707) 294-1299 for international callers, using the conference ID# 87699634. The webcast can be accessed live on the Investor Relations page of
Tobiras website, http://ir.tobiratx.com, and will be available for replay for 30 days following the call.

About Cenicriviroc (CVC) and
Non-alcoholic Steatohepatitis (NASH)

CVC is an oral, once-daily, potent immunomodulator that blocks two chemokine receptors, CCR2 and CCR5, which are
intricately involved in the inflammatory and fibrogenic pathways in NASH that cause liver damage and often lead to cirrhosis, liver cancer or liver failure. Tobira believes this novel approach will establish CVC as both a single-agent and as a
cornerstone treatment in multi-therapy regimens for NASH, for which there is currently no approved drug.

NCT02217475) and the company expects to announce the studys primary endpoint in the third quarter of 2016. CENTAUR is comparing CVC to placebo in 289 patients with NASH and liver fibrosis. CVC has been granted Fast Track status in
patients with NASH and liver fibrosis, the patient population at highest risk of progression to cirrhosis. The CENTAUR study includes surrogate endpoints identified as suitable for registrational studies in findings of an FDA-AASLD workshop reported
in Hepatology. To date, approximately 600 subjects have been dosed with CVC in Phase 1 and Phase 2b clinical studies, including 115 HIV infected subjects on treatment for up to 48 weeks.

NASH is an emerging health crisis impacting 3% to 5% of the U.S. population and 2% to 4% globally. It is the fastest growing cause of liver cancer and liver
transplant in the U.S. due to the rise in obesity. Additionally, this population is estimated to be three to five times larger than the size of the population with hepatitis C in the U.S.

About Evogliptin

Evogliptin (Suganon®, evogliptin 5mg) is an orally bioavailable, selective dipeptidyl peptidase-4 (DPP-4; CD26 antigen) inhibitor. DPP-4 inhibitors control glucose levels by preventing the breakdown of the incretin
hormones glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), which stimulate insulin secretion in response to the increased levels of glucose in the period following meals. In October 2015, evogliptin received its
first global approval in the Republic of Korea for blood glucose control in patients with type 2 diabetes mellitus. Evogliptin is not currently approved by the FDA.
