country in the Territory regarding any payment to Daiichi Sankyo, such amount shall be deducted from the payment to be made by Odonate, provided that Odonate shall take reasonable and lawful actions to avoid and minimize such withholding and
promptly notify Daiichi Sankyo so that Daiichi Sankyo may take lawful actions to avoid and minimize such withholding. Odonate shall promptly furnish Daiichi Sankyo with copies of any tax certificate or other documentation evidencing such
withholding, as necessary to enable Daiichi Sankyo to support a claim, if permissible, for income tax credit in respect of any amount so withheld. Each Party agrees to cooperate with the other Party in claiming exemptions from such deductions or
withholdings under any agreement or treaty in effect from time to time. 
 5.8. Records. Odonate shall keep, and
shall cause its Affiliates and sublicensees to keep, complete, true and accurate books of accounts and records, in compliance with applicable law and the terms and conditions of this Agreement, sufficient to determine and establish the calculation

maintained by Odonate and its Affiliates and sublicensees for a period of five (5) years after the year in which the sale of the Product generating the same occurred. 

5.9. Inspection of Records. At the request of Daiichi Sankyo, Odonate, its Affiliates and sublicensees shall permit
an independent certified public accountant appointed by Daiichi Sankyo, and reasonably acceptable to the Selling Party, to inspect the books and records described in Section 5.8; provided that such inspection shall be at reasonable times and
upon reasonable notice and not more often than once per calendar year. Any inspection conducted under this Section 5.9 shall be at the expense of Daiichi Sankyo, unless such inspection reveals any underpayment of any amount due to Daiichi
Sankyo hereunder of at least * * * during the audited period, in which case the full costs of such inspection for such period shall be borne by the Selling Party being audited. Any underpayment shall be paid by Odonate to Daiichi Sankyo within * * *
business days with interest on the underpayment at the rate specified in Section 
5.6 from the date such payment was originally due until paid. 
 6. Intellectual Property. 

6.1. Filing, Prosecution and Maintenance of Patents. 

6.1.1. Odonate shall control the preparation, filing (including filing for correction of claims or specifications), prosecution, maintenance and
defense (including responses to patent office communications, any office actions, oppositions, interferences and challenges (whether before a patent authority or judicial body) related thereto) to the Daiichi Sankyo Patents, at Odonate’s
expense, as well as preparation and filing for any patent term extensions or similar protections therefor. 
 6.1.2. If Odonate declines to prepare,
file (including filing for correction of claims or specifications), prosecute, maintain or defend (including responses to patent office communications, any office actions, oppositions, interferences and challenges (whether before a patent authority
or judicial body) related thereto) any Daiichi Sankyo Patent, it shall give Daiichi Sankyo reasonable notice thereof (with sufficient time for Daiichi Sankyo to assume control thereof and continue such preparation, filing (including filing for
correction of claims or specifications), prosecution, maintenance or defense prior to expiration or termination of any relevant time period), and thereafter Daiichi Sankyo may, at Daiichi Sankyo’s sole cost, control the preparation, filing
(including filing for correction of claims or specifications), prosecution, maintenance and defense (including responses to patent office communications, any office actions, oppositions, interferences and challenges related thereto) of such item
thereafter. All rights in any patent obtained by Daiichi Sankyo after Odonate declines further preparation, filing, prosecution, maintenance or defense shall be excluded from the licenses granted under Section 2.1 of this Agreement. 

6.2. Defense of Infringement Claims By Third Parties. 

6.2.1. In the event of the institution or threatened institution of any suit by a Third Party against Odonate for infringement involving the
manufacture, use, offer for sale, sale, importation or exportation of API or Product in the Territory, Odonate shall have the right to defend such suit at its own expense and shall be responsible for all damages incurred as a result

thereof, subject to Odonate’s rights under Section 9.1. Daiichi Sankyo hereby agrees to assist and cooperate with Odonate, at Odonate’s reasonable request. Odonate shall reimburse
Daiichi Sankyo for all reasonable expenses incurred in assisting in the defense of such suit. 
 6.2.2. Odonate shall solely control the defense of
such a claim and shall also have the right to control settlement of such claim, provided, however, that any such settlement shall not adversely affect Daiichi Sankyo’s rights or interests without Daiichi Sankyo’s prior written consent,
which shall not be unreasonably withheld or delayed. 
 6.3. Enforcement Actions Against Third Parties. 

6.3.1. If either Party learns of an infringement, unauthorized use, misappropriation or ownership claim or threatened infringement or other such claim
by a Third Party with respect to the API or Product within the Territory, such Party shall promptly notify the other Party in writing and shall promptly provide such other Party with available evidence of such infringement or other such claim. 

6.3.2. Odonate shall have the first right, but not the duty, to institute an infringement suit or take other appropriate action against Third Parties
in the Territory (“Enforcement Action”). Upon request from Odonate, Daiichi Sankyo will provide reasonable assistance to Odonate, including being named as a plaintiff in such Enforcement Action if necessary. If Odonate does not
secure actual cessation of such infringement or institute an infringement proceeding (which may include sending a cease and desist letter), against an offending Third Party, Odonate shall notify Daiichi Sankyo of such determination as soon as
reasonably practicable but in any case no later than * * * days of learning of such infringement. Upon receipt of such notice or absent such notice within such * * * days, Daiichi Sankyo shall have the right at its sole discretion to institute an
Enforcement Action in the name of either or both Parties. Each Party shall execute all necessary and proper documents, take such actions as shall be appropriate to allow the other Party to institute and prosecute such infringement actions and shall
otherwise cooperate in the institution and prosecution of such actions (including, without limitation, consenting to being named as a nominal party thereto). 

6.3.3. The costs and expenses of any such Enforcement Action (including fees of attorneys and other professionals) shall be borne by the Party
instituting the action, or, if the Parties elect to cooperate in instituting and maintaining such action, such costs and expenses shall be borne by the Parties in such proportions as they may agree in writing. Any award paid by Third Parties as a
result of such an Enforcement Action (whether by way of settlement or otherwise) shall be applied first to reimburse both Parties for all costs and expenses incurred by the Parties with respect to such action on a pro rata basis, and, if after such
reimbursement any funds shall remain from such award, they shall be allocated on the same proportion to the costs and expenses incurred by the Parties. 

6.4. Improvements. From time to time, each Party shall keep the other Party informed of material Know-How and
Patents that such Party has developed or acquired that it believes may be of interest to the other Party. If requested, such Party shall engage in good faith negotiations concerning the commercial terms and consideration for a license to such
Know-

How or Patent. For clarity, the foregoing shall be subject to any legal or contractual restrictions that may apply. 

6.5. Trademarks. If a Product receives Regulatory Approval and is being marketed pursuant to Section 3.5, then
Odonate or any sublicensee shall market the Product under a trademark or trademarks (collectively, the “Trademarks”) selected by Odonate or the sublicensee(s), as applicable. 

7. Confidentiality. 
 
7.1. Confidentiality; Exceptions. Except to the extent expressly authorized by this Section 7 or otherwise agreed in writing, each Party hereby agrees that, during the Term of this Agreement and * * * years thereafter, it (the
“Receiving Party”) shall keep confidential and shall not publish or otherwise disclose or use for any purpose other than as explicitly provided for in this Agreement any confidential and proprietary information of materials,
patentable or otherwise, in any form (written, oral, photographic, electronic, magnetic, or otherwise) that is disclosed to it by the other Party (the “Disclosing Party”) or otherwise received or accessed by a Receiving Party in the
course of performing its obligations under this Agreement including, but not limited to, any trade secrets, Know-How, Product specifications, formulae, processes, techniques and information relating to a Party’s past, present and future
marketing, financial, and research and development activities for any product of the Disclosing Party and the pricing thereof (collectively, “Confidential Information”). Confidential Information of each Party includes the terms and
conditions of this Agreement. Notwithstanding the foregoing, Confidential Information shall not be deemed to include information or materials to the extent that it can be established by the Receiving Party that such information or material: 

7.1.1. is already lawfully known to the Receiving Party, other than under an obligation of confidentiality at the time of disclosure by the Disclosing
Party as evidenced by written records kept in the ordinary course of business, or other documentary proof of actual use by the Receiving Party; 

7.1.2. is generally available to the public or otherwise part of the public domain at the time of its disclosure to the Receiving Party; 

7.1.3. becomes generally available to the public or otherwise part of the public domain after its disclosure to the Receiving Party and other than
through any act or omission of the Receiving Party or its Affiliates in violation of this Agreement; 
 7.1.4. is independently developed by the
Receiving Party as demonstrated by documented evidence prepared contemporaneously with such independent development; 
 7.1.5. is lawfully disclosed

 7.2. Authorized Disclosure. Notwithstanding Section 7.1, each
Party may disclose Confidential Information of the Disclosing Party: 
 7.2.1. to its respective employees, consultants and advisors, and to the
employees, consultants and advisors of such Party’s Affiliates, sublicensees or potential investors or sublicensees, who have a need to know such Confidential Information in connection with the activities or transactions contemplated hereby and
have an obligation to treat such Confidential Information as confidential under terms no less restrictive than those set forth herein; or 
 7.2.2.
if required to be disclosed in response to a valid order by a court or other governmental body and provided that the Receiving Party provides the Disclosing Party with prompt notice of such requirement so that the Disclosing Party may seek a
protective order or other appropriate remedy, then the Receiving Party may furnish only that portion of the Confidential Information which the Receiving Party is legally compelled to disclose; or 

7.2.3. if required to be disclosed in connection with any legal or regulatory requirements or obligations, including SEC filings or Regulatory Filings,

7.2.4. in its publicly filed financial statements or other public statements pursuant to applicable laws, regulations, and stock exchange rules or
otherwise disclosed pursuant to applicable law; provided, that: (i) the terms of this Agreement shall be redacted to the greatest extent reasonably possible; and (ii) such Party shall provide the other Party with a copy of the proposed
text of such statements or disclosure (including any exhibits containing this Agreement) sufficiently in advance of the scheduled release or publication thereof to afford such other Party a reasonable opportunity to review and comment upon the
proposed text (including redacted versions of this Agreement). 
 7.2.5. to governmental authorities to facilitate the issuance of Marketing
Approvals for Product; provided that reasonable measures shall be taken to assure confidential treatment of such information; 
 7.2.6. to the extent
such disclosure is reasonably necessary in filing or prosecuting patent, copyright and trademark applications, prosecuting or defending litigation, complying with applicable governmental regulations, conducting preclinical activities or clinical
trials and marketing the Product; and 
 7.2.7. to Third Parties in connection with a Receiving Party’s efforts to secure financing or enter
into strategic partnerships, provided such information is disclosed only on a need-to-know basis and under confidentiality provisions at least as stringent as those in this Agreement. 

7.3. Publications. In the event Odonate (including its Affiliates and/or sublicensees, but excluding such
Party’s clinical investigators) proposes a publication that includes information related to the API or Product that includes Confidential Information of Daiichi Sankyo, Odonate shall first submit to Daiichi Sankyo an early draft of all such
publications,

whether they are to be presented orally or in written form, at least * * * days prior to submission for publication or presentation. Daiichi Sankyo shall review such proposed
publication/presentation in order to avoid the unauthorized disclosure of its Confidential Information and to preserve the patentability of inventions and shall, as soon as reasonably possible, but no more than * * * days from receipt of the advance
copy of a Odonate’s proposed publication, inform Odonate if: 
 7.3.1. its proposed publication contains Confidential Information of Daiichi
Sankyo, in which case Odonate shall delete such Confidential Information from its proposed publication; and 
 7.3.2. its proposed publication could
be expected to have a material adverse effect on any Patent, Know-How, compound or product of Daiichi Sankyo, then Odonate shall delay such proposed publication sufficiently long to permit the timely preparation and first filing of patent
application(s) on the information involved. 
 7.4. Press Release. Neither Party shall issue any press release
relating to this Agreement without obtaining the other Party’s prior written approval, which approval shall not be unreasonably withheld or delayed, provided that such approval shall not be required for a press release issued in connection with

upon execution by the other Party, shall be enforceable in accordance with its terms except to the extent that enforceability may be limited by applicable bankruptcy, insolvency or other laws affecting the enforcement of creditors’ rights
generally and subject to the general principles of equity (regardless of whether enforcement is sought in a court of law or equity); 
 8.1.4. the
execution, delivery and performance of this Agreement by such Party does not conflict with any agreement, instrument or understanding, oral or written, to which it is a party or by which it may be bound, nor violate any material law or regulation of
any governmental agency or Regulatory Authority having jurisdiction over it;

8.1.7. it is not aware of any action, suit or inquiry or investigation instituted by any person or governmental agency that questions or threatens the

8.4. Disclaimer of Warranties. EXCEPT AS EXPRESSLY SET FORTH IN THIS SECTION 8, DAIICHI SANKYO DISCLAIMS ANY
REPRESENTATIONS OR EXTENDS ANY WARRANTIES OF ANY KIND UNDER THIS AGREEMENT (INCLUDING WITH RESPECT TO ANY MATERIALS PROVIDED UNDER THIS AGREEMENT), EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF MERCHANTABILITY, QUALITY,

 8.5. Limitation of Liability. IN NO EVENT SHALL EITHER PARTY BE
LIABLE TO THE OTHER PARTY OR ANY OTHER PERSON FOR INCIDENTAL, CONSEQUENTIAL, EXEMPLARY, PUNITIVE, MULTIPLE OR OTHER INDIRECT DAMAGES, OR FOR LOSS OF PROFITS, LOSS OF DATA OR LOSS OF USE DAMAGES, ARISING OUT OF THIS AGREEMENT, WHETHER BASED UPON
WARRANTY, CONTRACT, TORT, STATUTE, STRICT LIABILITY OR OTHERWISE, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR LOSSES. THE FOREGOING LIMITATION OF LIABILITY SHALL NOT LIMIT THE OBLIGATIONS OF EITHER PARTY TO INDEMNIFY
THE OTHER PARTY FROM AND AGAINST THIRD PARTY CLAIMS UNDER SECTION 9. 
 9. Indemnification. 

9.1. Indemnification by Daiichi Sankyo. Daiichi Sankyo hereby agrees to defend, hold harmless and indemnify
(collectively “Indemnify”) Odonate and its Affiliates, and its and their respective agents, directors, contractors, representatives, officers and employees (the “Odonate Indemnitees”) from and against any liability
or expense (including without limitation reasonable legal expenses and attorneys’ fees) (collectively “Losses”) resulting from suits, claims, actions and demands, in each case brought by a Third Party (each, a
“Third-Party Claim”) relating to or arising from: (i) a material breach of any of Daiichi Sankyo’s representations, warranties or covenants under Sections 8.1 or 8.2 or other obligations pursuant to this Agreement; or
(ii) any gross negligence, willful misconduct or wrongful intentional acts or omissions of Daiichi Sankyo or their officers, directors, employees, contractors, consultants, agents, or representatives in the exercise of any of Daiichi
Sankyo’s rights or the performance of any of Daiichi Sankyo’s obligations under this Agreement. Daiichi Sankyo’s obligation to Indemnify the Odonate Indemnitees pursuant to the foregoing sentence shall not apply to the extent that any
such Losses: (a) arise from the gross negligence, willful misconduct or wrongful intentional acts or omissions of any Odonate Indemnitee; or (b) are Losses for which Odonate is obligated to Indemnify the Daiichi Sankyo Indemnitees pursuant
to Section 9.2. 
 9.2. Indemnification by Odonate. Odonate hereby agrees to Indemnify Daiichi Sankyo and
its Affiliates, and its and their agents, directors, contractors, representatives, officers and employees (the “Daiichi Sankyo Indemnitees”) from and against any and all Losses resulting from Third-Party Claims relating to or
arising from: (i) a material breach of any of Odonate’s representations, warranties or covenants under Section 8.1 or 8.3 or other obligations pursuant to this Agreement; (ii) any gross negligence, willful misconduct or wrongful
intentional acts or omissions of Odonate, its Affiliates, or their officers, directors, employees, contractors, consultants, agents, representatives, or sublicensees in the exercise of any of Odonate’s rights or the performance of any of
Odonate’s obligations under this Agreement; (iii) any tort claims of personal injury (including death) or property damage relating to or arising out of any sale, offer for sale or importation of any Product in the Territory by Odonate, its
Affiliates or sublicensees; or (iv) any claims relating to or arising out of the marketing or sales activities in the Territory, as such, of Odonate, its Affiliates or its sublicensees. Odonate’s obligation to Indemnify the Daiichi Sankyo
Indemnitees pursuant to the foregoing sentence shall not apply to the extent that any such Losses: (a) arise from the gross negligence, willful misconduct or wrongful intentional acts or omissions of any Daiichi Sankyo Indemnitee; (b) are

obligated to Indemnify the Odonate Indemnitees pursuant to Section 9.1; or (c) otherwise arose prior to the Effective Date. 

9.3. Procedure. To be eligible to be indemnified hereunder, any Odonate Indemnitee under Section 9.1, or
Daiichi Sankyo Indemnitee under Section 9.2, as the case may be (an “Indemnitee”) seeking indemnification, shall provide the indemnifying Party with prompt notice of the Third-Party Claim giving rise to the indemnification
obligation and with the exclusive ability to defend (with the reasonable cooperation, at the indemnifying Party’s expense, of the Indemnitee) or settle any such claim; provided, however, that the indemnifying Party shall not enter into any
settlement that admits fault, wrongdoing or damages on the part of the Indemnitee or the other Party without such Indemnitee’s and/or other Party’s written consent, such consent not to be unreasonably withheld or delayed. The Indemnitee
shall have the right to participate, at its own expense and with counsel of its choice, in the defense of any claim or suit that has been assumed by the indemnifying Party. 

9.4. Complete Indemnification. Indemnification hereunder shall include the reasonable costs and expenses, excluding
legal fees, and any damages awarded in a final, non-appealable judgment or settlement against an Indemnitee and/or the indemnified Party in connection with enforcement of Sections 9.1 and 9.2. 

9.5. Allocation. In the event a claim is based partially on an indemnified claim described in Sections 9.1 and 9.2
and partially on a non-indemnified claim, or is based partially on a claim described in Section 9.1 and partially on a claim described in Section 9.2, any payments and reasonable attorney fees incurred in connection with such claims are to
be apportioned between the Parties or between the indemnifying Party and an Indemnitee, as the case may be, in accordance with the degree of cause attributable to each Party and/or person. 

9.6. Insurance. During the Term and for * * * years thereafter, Odonate shall maintain a policy of insurance at
levels sufficient to support its indemnification obligations, but in any case such insurance shall provide adequate coverage for clinical trials liability, products liability, worker’s compensation, employer’s liability, and comprehensive
general liability. 
 10. Term and Termination. 

10.1. Term. This Agreement shall become effective as of the Effective Date and, unless earlier terminated pursuant
to the other provisions of this Section 10, shall continue in full force and effect on a country-by-country basis until expiration of the Royalty Term in such country (the “Term”). 

10.2. Termination by Daiichi Sankyo. 

10.2.1. Daiichi Sankyo may terminate this Agreement, without prejudice to any other remedies available to it at law or in equity, in the event Odonate
commits a material breach of this Agreement that, in the case of a material breach capable of remedy, shall not have been remedied within * * * days of the receipt by it of a notice identifying the breach and requiring its remedy, or if such
material breach cannot be cured within such * * * day period, if Odonate does not commence and diligently continue actions to cure such breach or default during such * * *

10.3. Termination by Odonate. 

10.3.1. Odonate may terminate this Agreement, without prejudice to any other remedies available to it at law or in equity, in the event Daiichi Sankyo

material breach cannot be cured within such * * * day period, if Daiichi Sankyo does not commence and diligently continue actions to cure such breach or default during such * * * days. 

10.3.2. Odonate may terminate this Agreement upon * * * prior written notice on a country-by-country basis or for the entire Territory if it:

for Product or other reasons it does not wish to continue the development and/or commercialization of Product in such country. Such notice for this Section 10.3.2(i) shall specify in detail Odonate’s basis for such termination, including a
reasonable description of such concerns. 
 10.4. Accrued Obligations/Survival. Expiration or termination of this
Agreement for any reason shall not release either Party from any obligation or liability which, at the time of such expiration or termination, has already accrued to the other Party or which is attributable to a period prior to such expiration or
termination. 5.8 (Inspection of Records), 7 (Confidentiality), 8.5 (Limitation of Liability), 9 (Indemnification.), this 10.4 (Accrued Obligations/Survival), 10.5 (Effects of Terminations), 11.9 (Governing Law) and 11.11 (Notices) shall survive

10.5.1. If Odonate electively terminates this Agreement in a country(ies) in the Territory or throughout the entire Territory pursuant to
Section 10.3.2 (the “Terminated Country(ies)”); in each case, then: 
 (a) if there are any ongoing clinical trials in such
Terminated Country(ies) being conducted by or on behalf of Odonate (or its Affiliate or sublicensee) at the time of notice of termination, Odonate agrees to, as of the termination date: (1) promptly transfer to Daiichi Sankyo or its designee
some or all of such clinical trials and the activities related to or

supporting such trials; or (2) terminate such clinical trials; in each case solely as requested by Daiichi Sankyo. If Daiichi Sankyo requests transfer of a clinical trial and the related or
supporting activities, Daiichi Sankyo shall be responsible for all further expenses related to continuation or completion of such trial. If Daiichi Sankyo elects to terminate the clinical trials in the Terminated Country(ies), but such clinical
trials are required or useful for Regulatory Filings or permitted activities with respect to the Product outside the Terminated Country(ies), then, notwithstanding the foregoing, Odonate shall have the option of completing such clinical trials
solely at its own expense.; 
 (b) Odonate shall: (1) at the request of Daiichi Sankyo, promptly transfer to Daiichi Sankyo copies of all data,
reports, records, materials that relate to Product in such Terminated Country(ies); (2) at the request of Daiichi Sankyo, provide Daiichi Sankyo with all information necessary or desirable to cross-reference or assume responsibility for any
Regulatory Filings, as the case may be, in Odonate’s name with respect to Product, in such Terminated Country(ies); and (3) return to Daiichi Sankyo all relevant records and materials in Odonate’s possession or Control containing
Confidential Information of Daiichi Sankyo relating solely to Product in such Terminated Country(ies) (provided that Odonate may keep one copy of such Confidential Information for archival purposes or as may be necessary or useful in connection with
Odonate’s activities under this Agreement outside of the Terminated Countries); 
 (c) at the request of Daiichi Sankyo, Odonate shall,
