Article 9PAYMENT; RECORDS; AUDITS

9.1    Payment; Reports. Royalties shall be calculated and reported for each Calendar Quarter within [***] days after the end of each Calendar Quarter. Each payment shall be accompanied by a report of [***]. Except as may otherwise be expressly provided herein, Licensee shall not have the right to set off, withhold or make any deduction from any payment of royalties or other payments due to Duality hereunder for any reason whatsoever.

9.2    Invoices. Duality will ensure that all invoices:

(a)    are delivered in accordance with the procedures set out in Schedule 9.2;

(b)    are in such form as Licensee reasonably requires; and

(c)    incorporate all information required by Licensee, as set out in Schedule 9.2.

9.3    Exchange Rate; Manner and Place of Payment. All payments hereunder shall be payable in U.S. dollars within [***] days after receipt of an invoice from Duality. With respect to sales of Licensed Products invoiced in a currency other than U.S. dollars, sales milestones and royalties shall be converted into U.S. dollar using the exchange rate mechanism generally applied by Licensee or its Affiliates or Sublicensees for consolidation purposes, in accordance with the Accounting Standards, for the Calendar Quarter for which a payment is due. All payments owed under this Agreement shall be made by wire transfer in immediately available funds to a bank and account designated in writing by Duality, unless otherwise specified in writing by Duality.

9.4    Taxes.

(a)Taxes on Income. Except as otherwise provided in this Section 9.4, Licensee shall be solely responsible for the payment of all value added taxes, fees, duties, surcharges, and other deductions or withholding taxes imposed by or on any entity in the Territory in connection with the payments and activities contemplated hereunder. Except as otherwise set forth in this Section, each Party shall be solely responsible for the payment of all taxes imposed on such Party’s income arising directly or indirectly from the activities of the Parties under this Agreement.

(b)Tax Withholdings. In the event that any withholding tax, fee, duty or surcharge applicable to or assessable in respect of any of the Upfront Payment, development, regulatory or sales milestone payments, or royalty payments to be made by Licensee to Duality under this Agreement (collectively, the “License Payments”) is required to be withheld and deducted under Applicable Laws (“Tax Withholdings”), Licensee (or its Affiliate paying on behalf of Licensee) shall make such deduction and withholding and will pay the remaining License Payments to Duality. For clarity, Licensee’s reimbursement of Duality Costs in the Territory shall not be deemed to be License Payments or subject to any Tax Withholdings. If Licensee did not conduct the Tax Withholding when making its payment(s) to Duality, but is later determined by Applicable Law to pay an amount of tax on account of Duality to the tax authorities, Duality will promptly refund that amount of Tax Withholdings to Licensee, provided that Duality shall not be liable for any interest or other penalty on such payments.

Page 36 of 92

(c)Tax Cooperation. Licensee shall make such deduction of taxes and withholding tax payments to the applicable taxing authority(ies) in a timely manner and shall promptly provide Duality with the appropriate proof of payment and relevant receipt(s) with respect to such deduction or withholding. To the extent permitted by Applicable Laws, Licensee shall provide Duality reasonable assistance in order to allow Duality to obtain the benefit of any present or future treaty against double taxation or refund or reduction in taxes which may apply to the License Payments. Each Party agrees to use commercially reasonable efforts to cooperate with the other Party in claiming refunds, reductions, or exemptions from such deductions or withholdings under any relevant agreement or treaty that is in effect. Duality will provide Licensee with any tax forms or other documentation reasonably necessary in order for Licensee not to withhold or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. If the taxes originally paid or otherwise borne by a Party are in whole or in part subsequently determined not to have been chargeable, all reasonably necessary steps will be taken by each Party to obtain a refund of these undue taxes from the applicable Governmental Authority or other fiscal authority and any amount of undue taxes repaid by such authority to the receiving Party will be transferred to the paying Party within [***] days of receipt.

9.5    Blocked Currency. In the event that, by reason of Applicable Law in any country or region, it becomes impossible or illegal, after reasonable efforts by Licensee to do so, for Licensee or its Affiliate to transfer, or have transferred on its behalf, payments owed Duality hereunder, Licensee shall promptly notify Duality of the conditions preventing such transfer and such payments will be deposited in local currency in the relevant country or region to the credit of Duality in a recognized banking institution designated by Duality provided such arrangements are legal under all Applicable Laws.

9.6    Records; Audits. Licensee shall keep, and require its Affiliates and Sublicensees to keep, complete, fair and true books of accounts and records for the purpose of determining the amounts payable to Duality pursuant to this Agreement. Such books and records shall be kept for at least [***] Years following the end of the Calendar Year to which they pertain. Duality shall have the right to cause an independent, certified public accountant reasonably acceptable to Licensee to audit such records to confirm Net Sales, royalties and other payments for a period covering not more than the preceding [***] Years; provided that (a) such audit shall not be more frequent than once in any [***] month period, and (b) once such accountant has conducted a review and audit of any records pursuant to this Section 9.6 in respect of any given period, it may not subsequently re-inspect such records with respect to such period, unless, in each case of (a) and (b), for cause. Prior to engagement by an independent, certified public accountant, such accountant must have executed and delivered to Licensee and its Affiliates a confidentiality agreement as reasonably requested by Licensee, which will include provisions limiting such accountant’s disclosure to Duality to only the results and basis for such results of such inspection. Such audits may be exercised during normal business hours upon reasonable prior written notice to Licensee. Prompt adjustments shall be made by the Parties to reflect the results of such audit. Duality shall bear the full cost of such audit unless such audit discloses an underpayment by Licensee of more than [***] of the amount of royalties or other payments due under this Agreement for any applicable Calendar Quarter, in which case, Licensee shall bear the cost of such audit and shall promptly remit to Duality the amount of any underpayment. Any overpayment by Licensee revealed by an audit shall be fully-creditable against future payment owed by Licensee to Duality (and if no further payments are due, shall be refunded by Duality at the request of Licensee). Any underpayment by Licensee identified by an audit shall not be subject to Section 9.7.

9.7    Late Payments. In the event that either Party fails to make any payment due under this Agreement (save as set out in Section 9.6), simple interest shall thereafter accrue on the sum due from the due date until the date of payment at [***].

10.3    Authorized Disclosure. Notwithstanding the provisions of Section 10.1, the Receiving Party may disclose Confidential Information of the Disclosing Party as expressly permitted by this Agreement, or if and to the extent such disclosure is reasonably necessary in the following instances:

(a)filing or prosecuting or defending Patents as permitted by this Agreement;

(b)disclosure required in connection with any judicial, regulatory or administrative process relating to or arising from this Agreement (including any enforcement hereof) or to comply with applicable court orders;

(c)disclosure to Affiliates, employees, contractors, consultants or agents of the Receiving Party who have a need to know such information in order for the Receiving Party to exercise its rights or fulfill its obligations under this Agreement; provided, in each case, that any such Affiliate, actual or potential licensee or Sublicensee, employee, contractor, consultant or agent agrees to be bound by terms of confidentiality and non-use comparable in scope to those set forth in this Article 10;

(d)such disclosure is made to such Party’s attorneys, independent accountants or financial advisors for the sole purpose of enabling such attorneys, independent accountants or financial advisors to provide advice to the Receiving Party, on the condition that such attorneys, independent accountants and financial advisors are bound by confidentiality and non-use obligations consistent with the confidentiality provisions of this Agreement as they apply to the Receiving Party (provided, however, that in the case of financial advisers, including investment bankers, the term of confidentiality may be

Page 38 of 92

shortened to [***] years from the date of disclosure and in the case of attorneys, no written agreement shall be required);

(e)disclosure to existing investors, acquirors or collaborators or potential bona fide investors, acquirors, licensees, Sublicensees or collaborators in connection with due diligence or similar investigations by such Third Parties; provided, in each case, that any such existing or potential investor, acquiror, licensees, Sublicensees or collaborator agrees to be bound by confidentiality and non-use obligations consistent with those contained in this Agreement as they apply to the Receiving Party (but of duration customary in confidentiality agreements entered into for similar purpose);

(f)disclosure to Regulatory Authorities as required by Applicable Laws in relation to Regulatory Approvals and regulatory procedures, proceedings and other filings;

(g)disclosure to: (i) Governmental Authorities to the extent useful or necessary to make regulatory filings and obtain or maintain Regulatory Approvals (including fulfilling post-approval regulatory obligations) for any Licensed Product; (ii) Governmental Authorities, technical committees or similar public health or scientific bodies for purposes of securing product use recommendations, tenders, direct procurement contracts or responding to relevant requests for information; (iii) comply with Applicable Laws with respect to performance under this Agreement; and (iv) to Governmental Authorities in order to respond to inquiries, requests or investigations relating to Licensed Products or this Agreement; and

(h)to the extent mutually agreed to by the Parties in writing.

Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s Confidential Information pursuant to Section 10.3(a) or Section 10.3(b), it will, except where impracticable for necessary disclosures, give reasonable advance notice to the other Party of such disclosure requirement and will use its reasonable efforts to secure and cooperate with the other Party, as necessary, to seek and obtain confidential treatment of such Confidential Information required to be disclosed to the extent legally permissible and will limit the disclosure of that Confidential Information required to be disclosure to (i) to advisors (including lawyers and accountants) or Governmental Authorities on a need to know basis, in each case under appropriate confidentiality provisions or professional standards of confidentiality substantially equivalent to those of this Agreement, or (ii) to the extent agreed to by the Parties.

10.4    Pubic Announcements.

Page 39 of 92

and which do not reveal non-public information about the other Party. In the event of a required public announcement, to the extent practicable under the circumstances, the Party making such announcement shall provide the other Party with a copy of the proposed text of such announcement sufficiently in advance of the scheduled release to afford such other Party a reasonable opportunity to review and comment upon the proposed text. Licensee shall have final decision making authority in respect of the proposed text of any required public announcement relating to the Licensed Product in the Territory and Retained Territory.

(ii)In the event of termination of this Agreement for any reason, if in the reasonable opinion of the either Party’s legal counsel, public disclosure of such termination is required under the Applicable Law or the rules of a stock exchange on which the securities of either Party (or any controlling Affiliate of such Party) are listed (or to which an application for listing has been submitted), the Parties shall cooperate in good faith to coordinate public disclosure, if any, of such termination and the reasons therefor. The principles to be observed in such disclosures shall be accuracy, compliance with Applicable Law, the rules of the applicable stock exchange and regulatory guidance documents, and reasonable sensitivity to potential negative investor reaction to such news and neither Party shall make any other public announcement or statement, whether oral or written, concerning the termination of this Agreement without the prior written consent of the other Party, which shall not be unreasonably withheld, conditioned or delayed.

After a publication has been made available to the public, each Party may post such publication or a link to it on its corporate web site without the prior written consent of the other Party.

(b)Filing of this Agreement. The Parties shall coordinate in advance with each other in connection with the filing of this Agreement (including redaction of certain provisions of this Agreement) with the SEC or any stock exchange or governmental agency on which securities issued by a Party or its Affiliate are traded, and each Party will use reasonable efforts to seek confidential treatment for the terms proposed to be redacted; provided that each Party will ultimately retain control over what information to disclose to the SEC or any stock exchange or other governmental agency, as the case may be, and provided further that the Parties will use their reasonable efforts to file redacted versions with any governing bodies which are consistent with redacted versions previously filed with any other governing bodies. Other than such obligation, neither Party (nor its Affiliates) will be obligated to consult with or obtain approval from the other Party with respect to any filings to the SEC or any stock exchange or other governmental agency.

10.5    Publication.

(a)If either Party proposes to publicly present or publish, in any publication or venue, in their respective Territories, any Clinical Trial data, non-clinical data or any associated results or conclusions generated by or on behalf of Licensee pursuant to Clinical Trials (each such proposed presentation or publication, a “Proposed Publication”), it shall obtain the other Party’s prior written consent and otherwise comply with this Section 10.5. The proposing Party shall provide the other Party with a copy of such Proposed Publication at least [***] days prior to the earlier of its presentation or intended submission for publication; provided that in the case of abstracts, this period shall be at least [***] Days (such applicable period, the “Review Period”).

Page 40 of 92

comments during such Review Period on the material in such Proposed Publication or (ii) until the applicable Review Period (as may be extended by subsection (C) below) has elapsed without written comments from the other Party, in which case the proposing Party may proceed and the Proposed Publication will be considered approved in its entirety. If the proposing Party receives written comments from the other Party during the applicable Review Period, it shall consider the comments of the other Party in good faith, but will retain the sole authority to submit the manuscript for such Proposed Publication;provided that the proposing Party agrees to (A) delete any Confidential Information of the other Party that the other Party identifies for deletion in the other Party’s written comments, (B) delete any Clinical Trial data, non-clinical data, results, conclusions or other related information that is not specific to or resulting from any Clinical Trial conducted in the proposing Party’s territory, and (C) delay such Proposed Publication for a period of up to an additional [***] days after the end of the applicable Review Period to enable the other Party to draft and file patents with respect to any subject matter to be made public in such Proposed Publication and to which the other Party has the applicable intellectual property rights to file such patents. The proposing Party shall provide the other Party a copy of the Proposed Publication at the time of the submission or presentation. The proposing Party shall require its Affiliates, (sub)licensees (in case that Duality is the proposing Party), Sublicensees (in case that Licensee is the proposing Party) and contractors to comply with the obligations of this Section 10.5 as if they were the proposing Party, and shall be liable for their non-compliance.

10.6    Publication and Listing of Clinical Trials. Each Partyagrees to comply, with respect to the listing of Clinical Trials or the publication of Clinical Trial information and results with respect to Licensed Products and to the extent applicable to its activities conducted under this Agreement, with any Applicable Law or applicable court order, stipulations, consent agreements and settlements entered into by such Party; provided that any listings or publications made pursuant to this Section 10.6 shall be considered a publication hereunder and shall be subject to Section 10.5.

10.7    Prior Non-Disclosure Agreement. As of the Effective Date, the terms of this Article 10 shall supersede any prior non-disclosure, secrecy or confidentiality agreement between the Parties (or their Affiliates) to the extent dealing with the subject of this Agreement. Any information disclosed pursuant to any such prior agreement relating to the subject to this Agreement shall be deemed Confidential Information for purposes of this Agreement.

10.8    Equitable Relief. Given the nature of the Confidential Information and the competitive damage that would result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages would not be a sufficient remedy for any breach of this Article 10. In addition to all other remedies, a Party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this Article 10.

Licensee shall indemnify and hold harmless each of Duality and its Affiliates and their respective directors, officers, employees, consultants, agents and successors and assigns of any of the foregoing (the “Duality Indemnitees”) from and against any and all losses, damages, liabilities, expenses and costs, including reasonable legal expense and attorneys’ fees (“Losses”), incurred by any Duality Indemnitee as a result of any claims, demands, actions, suits or proceedings brought by a Third Party (“Third Party Claims”) arising directly or indirectly out of: (a) the practice by Licensee or its Affiliates or Sublicensees or subcontractors of the licenses granted to Licensee under this Agreement; (b) the research, Development, Manufacture or have Manufactured, use, handling, storage, Commercialization or other disposition of the Licensed Compound or the Licensed Products by Licensee or its Affiliates or Sublicensees or subcontractors; (c) the negligence or willful misconduct of any Licensee Indemnitee; or (d) any breach of any representations, warranties or covenants by Licensee under this Agreement; except, in each case, (x) to the extent such Third Party Claims fall within the scope of the indemnification obligations of Duality set forth in Section 14.2, or (y) arising from or occurring as a result of a Duality Indemnitee’s negligence, illegal conduct or willful misconduct in performing its or their obligations or exercising their rights under this Agreement. Licensee’s indemnification obligation specifically excludes any and all Third Party Claims for the use of any Patents, Know-How or other intellectual property rights under any Third Party agreements entered into by Duality prior to the Effective Date, including but not limited to the payment of royalties thereunder.

14.2    Indemnification of Licensee. Duality shall indemnify and hold harmless each of Licensee and its Affiliates and their respective directors, officers, employees, consultants, agents and successors and assigns of any of the foregoing (the “Licensee Indemnitees”), from and against any and all Losses incurred by any Licensee Indemnitee as a result of any Third Party Claims arising directly or indirectly out of: (a) the practice by Duality or its Affiliates or sublicensees or subcontractors of the license granted to Duality under Section 2.5; (b) the research,

Page 49 of 92

Development, Manufacture or have Manufactured, use, handling, storage, Commercialization or other disposition of the Licensed Compound or Licensed Products by Duality or its Affiliates or sublicensees or subcontractors; (c) the negligence or willful misconduct of any Duality Indemnitee; or (d) any breach of any representations, warranties or covenants by Duality under this Agreement; except, in each case, (x) to the extent such Third Party Claims fall within the scope of the indemnification obligations of Licensee set forth in Section 14.1, or (y) arising from or occurring as a result of a Licensee Indemnitee’s negligence, illegal conduct or willful misconduct in performing its or their obligations or exercising their rights under this Agreement. In addition to the above, and not subject to (x), regardless of any information provided by Duality to Licensee regarding Third Party Agreements entered into prior to the Effective Date, Duality’s indemnification obligation shall cover any and all Third Party Claims for the use of any Patents, Know-How or other intellectual property rights under any Third Party Agreements entered into by Duality prior to the Effective Date, including but not limited to the payment of royalties thereunder.

14.3    Procedure. If any Duality Indemnitee or Licensee Indemnitee intends to claim indemnification under this Article 14 (the “Indemnitee”), Duality or Licensee, as the case may be, shall promptly notify the indemnifying Party (the “Indemnitor”) in writing of any Third Party Claim, in respect of which the Indemnitee intends to claim such indemnification. Each indemnification claim notice must contain a description of the claim, the nature and amount of such loss (to the extent known at the time). The Indemnitor shall have sole control of the defense and/or settlement thereof and the Indemnitee shall be entitled to participate in (but not control) the defense of such Third Party Claim and to employ counsel of its choice for this purpose, at its own expense. The indemnity arrangement in this Article 14 shall not apply to amounts paid in settlement of any action with respect to a Third Party Claim, if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld, conditioned or delayed unreasonably. The failure to deliver written notice to the Indemnitee within a reasonable time after the commencement of any action with respect to a Third Party Claim shall only relieve the Indemnitor of its indemnification obligations under this Article 14 if and to the extent the Indemnitee is actually prejudiced thereby. Duality or Licensee, as the case may be, and the Indemnitee shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action with respect to a Third Party Claim covered by these indemnification provisions. The Indemnitor shall not settle any Third Party Claim without the prior written consent of the Indemnitee if the settlement is reasonably expected to: (a) result in or impose any obligation (including any payment obligation) on the Indemnitee or otherwise adversely affect the business of the Indemnitee in any manner, or (b) result in any admission of wrong-doing or fault by the Indemnitee. The costs and expenses, including fees and disbursements of counsel, incurred by the Indemnitee in connection with any claim shall be reimbursed by the Indemnitor on a Calendar Quarter basis, without prejudice to the Indemnitor’s right to contest the Indemnitee’s right to indemnification and subject to refund in the event the Indemnitee is ultimately held not to be obligated to indemnify the Indemnitee.

14.4    Insurance. Each Party, at its own expense, shall maintain product liability and other appropriate insurance (or self-insure) in an amount consistent with sound business practice and reasonable in light of its obligations under this Agreement during the Term. Each Party shall provide a certificate of insurance (or evidence of self-insurance) evidencing such coverage to the other Party upon request. Such insurance shall not be construed to create a limit on either Party’s liability with respect to its indemnification obligations under this Article 14.
