4.2.1 Subject to Section 3.1.2, Recepta shall be solely responsible for, and shall use Diligent Efforts in connection with, the submission of information to, communicating with, and seeking Regulatory Approvals for Licensed Products in the Recepta Territory and will keep Mersana informed of all significant issues arising therefrom and material developments with respect thereto. Recepta will take into account Xxxxxxx’s reasonable suggestions and comments with respect to the materials and information which Recepta decides to submit to ANVISA in respect of the Licensed Products in the Recepta Territory. If and to the extent access to information, data (including Clinical Trial results), or materials (including samples of the relevant Licensed Product to the extent required in connection with Recepta’s application for Regulatory Approval) to which Recepta is not otherwise afforded access hereunder is necessary for Recepta to obtain and/or maintain Regulatory Approval in the Recepta Territory, Recepta shall notify Mersana in writing and Mersana shall make such information, data and/or materials

available to Recepta as soon as practicable, it being understood that Recepta’s receipt, use and disclosure of such information, data and/or materials shall be subject to the terms, conditions and limitations of this Agreement.

4.2.2 As between the Parties, Recepta shall own all Regulatory Approvals for the Recepta Territory. Recepta shall provide Mersana with reasonable advance notice of any meetings and other communications with ANVISA, and shall also provide Mersana with copies of any filings with ANVISA related thereto prior to submission to ANVISA for Xxxxxxx’s review and approval (such approval not to be unreasonably withheld, conditioned or delayed). Recepta hereby grants to Mersana (or its designated sublicensee), a right of reference to all such filings for all uses in connection with the obtaining or maintaining any Regulatory Approvals for Licensed Products outside the Recepta Territory. For so long as the license granted to Mersana under Section 2.1.1 remains in effect, Recepta shall not assign or transfer any Regulatory Approvals for the Recepta Territory to any Affiliate or Third Party without the prior written consent of Xxxxxxx, except in connection with a permitted assignment of the entire Agreement pursuant to Section 11.10. In such case, any Regulatory Approvals in the Recepta Territory must also be contemporaneously assigned and transferred to the applicable assignee unless the Parties agree otherwise in writing.

4.3 Cooperation; Costs and Expenses. Each Party shall provide all reasonably requested assistance to the other Party as may be required by such requesting Party where liaison between the Parties is, or may be, necessary to enable such Party to fulfill its responsibilities hereunder. Each Party shall be fully responsible for bearing all costs and expenses associated with its own submissions of information to, communications with, and seeking of Regulatory Approval for which and for so long as they have the responsibility pursuant to this Article 4, including, but not limited to, the costs of preparing and prosecuting applications for such Regulatory Approvals and fees payable to Regulatory Authorities in obtaining same.

4.4 Drug Safety Information. Both Parties shall comply fully with all applicable adverse event reporting recommendations and requirements in all countries where the Parties intend to market the Licensed Products and agree to exchange such information as may be necessary to achieve that end and to ensure that both Parties are completely informed regarding adverse events with respect to Licensed Products. This includes single case reports, together with an appropriate medical evaluation, as well as aggregate data, such as PSURs required by authorities. Both Parties will execute and implement a detailed pharmacovigilance agreement pertaining to Licensed Products in the Recepta Territory no later than [**] months before the earlier of the following events: (i) Recepta or Mersana is physically and/or legally able to distribute Licensed Products in the market, in a clinical trial or for whatever purpose, or (ii) Recepta or Mersana has a Regulatory Approval, a clinical trial authorization, or has regulatory reporting obligations for any other reason.

4.5 Recalls or Corrective Action. Xxxxxxx shall have sole responsibility for and shall make all decisions with respect to any recall, market withdrawal or other corrective action related to the Licensed Products in the Territory, provided, however, that Mersana shall notify Recepta as soon as reasonably practicable of any anticipated recall, market withdrawal or other corrective action related to any Licensed Products in the Territory and shall consult Recepta prior to making any such decision with respect to Licensed Products sold in the Recepta Territory and take into account Recepta’s views and interests in making its decision with respect thereto, provided such consultation does not delay or endanger the recall process. Mersana shall be solely responsible for all costs and expenses associated with such recall, market withdrawal or corrective action, including, but not limited to, all fines, fees and refunds to distributors and other customers and Mersana shall reimburse Recepta for any such amounts incurred by Recepta at Xxxxxxx’s request in connection therewith, unless the recall was caused by any act, omission or breach of this Agreement by Recepta, in which case Recepta shall bear all such costs and

expenses. Without limiting the foregoing, in the event that Recepta or any of its sublicensees is required by Applicable Law to undertake any recall, market withdrawal or other corrective action in respect of any Licensed Product in the Recepta Territory, Recepta shall promptly notify Mersana in writing. If, after receipt of such written notice, Xxxxxxx fails to commence such recall, market withdrawal or other corrective action in the Recepta Territory within the time period mandated by Applicable Law or, in the absence of any legally mandated time period, within [**] Business Days after its receipt of Recepta’s written notice, then Recepta or its sublicensee shall have the right to undertake the same on its own behalf, in accordance with Applicable Law and all of Mersana’s reasonable instructions with respect thereto until such time as Xxxxxxx notifies Recepta in writing that it will assume control over such recall, market withdrawal or corrective action. Mersana shall reimburse Recepta for its costs and expenses with respect thereto unless the recall was caused by an act, omission or breach of this Agreement by Recepta, in which case Mersana shall not be obligated to reimburse Recepta for its costs and expenses.

4.6 Events Affecting Integrity or Reputation. During the Term, the Parties shall notify each other promptly of any circumstances of which they are aware and which could reasonably be expected to impair the integrity and reputation of Licensed Products or if a Party is threatened by or becomes aware of unlawful activity in relation to Licensed Products, including, but not limited to, deliberate tampering with or contamination of Licensed Products.

5. FINANCIAL PROVISIONS. In consideration of the rights granted by the Parties to one another hereunder, particularly the licenses set forth in Article 2 above, the Parties agree to make the following payments:

5.1 Execution Payment. Within [**] Business Days after the Effective Date, Mersana shall pay to Recepta a non-creditable, non-refundable license fee of one million dollars (US$1,000,000).

5.2 Development Milestone Payments. In the event Mersana or its Affiliate or sublicensee achieves a Development milestone specified below, Mersana shall promptly, but in no event more than [**] Business Days after the achievement of each such milestone, notify Recepta in writing of the achievement of such milestone. Mersana shall pay to Recepta the corresponding non-refundable, non-creditable milestone payments as specified below within [**] after achievement of the particular milestone. If requested by Xxxxxxx, Recepta shall provide a written invoice for any such Development milestone payment promptly following Xxxxxxx’s notice to Recepta of the achievement thereof, provided, however, that the provision of such invoice shall not be a precondition of Xxxxxxx’s obligation to make such payment. The full milestone payments shall be payable [**] for each of the first Licensed Product to achieve such milestones and the second Licensed Product to achieve such milestones, regardless of the total number of Licensed Products to achieve the applicable milestone or the number of times each such milestone is achieved for a given Licensed Product. No milestone payments will be due in respect of subsequent achievement of the same milestone for the same Licensed Product. All

milestone payments will apply whether Licensed Products are Developed and Commercialized as single or Combination Products.

5.3 Commercialization Milestone Payments. In the event that Mersana Annual Net Sales reach one or more of the amounts set forth below, Xxxxxxx will make the corresponding milestone payment(s) specified below to Recepta no later than [**] calendar days following the end of the calendar year in which such Mersana Annual Net Sales milestone(s) was achieved. Each such milestone payment shall be non-refundable and non-creditable and shall be payable one time only. In the event that more than one of the Mersana Annual Net Sales milestones is first achieved in the same calendar year, then each corresponding milestone payment shall be payable following the end of such calendar year in accordance with the foregoing.

5.4 Royalties on Mersana Annual Net Sales.

5.4.1 Mersana will make royalty payments based on Mersana Annual Net Sales from the date of the First Commercial Sale of the [**] Licensed Product outside the Recepta Territory until the expiration of the Royalty Term. Upon expiration of the Royalty Term for a particular Licensed Product in a particular country, no Net Sales of such Licensed Product in such country following the last day of such Royalty Term shall be included in Mersana’s Annual Net Sales for purposes hereof. Such royalty payments shall be calculated based on year-to-date Mersana Annual Net Sales, applying the tiered royalty rates shown below:


Mersana Annual Net Sales						Royalty Rate
[**]						[**]
[**]						[**]
[**]						[**]

For avoidance of doubt, the following example shall illustrate the royalty payment calculation: Royalties on aggregate Net Sales outside the Recepta Territory in a calendar year shall be paid at the rate applicable to the portion of Net Sales within each of the Net Sales levels during such calendar year. For example, if, during a calendar year, aggregate Net Sales outside the Recepta Territory were equal to [**], then the royalties payable would be calculated by adding (i) the royalties with respect to the first [**] at the first-level percentage of [**]; and (ii) the royalties with respect to the next [**] at the second-level percentage of [**], for a total royalty of [**].

5.4.2 Mersana shall be solely responsible for all royalties, milestone payments, fees or other amounts due to any Third Parties to obtain any rights to any intellectual property that Mersana reasonably determines, based on the advice of outside legal counsel, is necessary to exercise the rights granted to Mersana under this Agreement or to enable Mersana to grant Recepta the licenses set forth in Sections 2.1.2 and 2.2.2 hereof (“Third Party IP”). Mersana shall be entitled to deduct from royalties owed to Recepta pursuant to this Section 5.4.2 [**] of all payments made by Mersana to any Third Party that are owed pursuant to any license agreement, settlement or award or judgment (including but not limited to damages) with or to a Third Party for Third Party IP (each, a “Third Party Payment”). Notwithstanding the foregoing, in no event shall Mersana be entitled to reduce the amount of any individual royalty payment owed to Recepta by more than [**] pursuant to this Section 5.4.2.

5.5 Royalties on Recepta Annual Net Sales. Recepta will make royalty payments based on Recepta Annual Net Sales from the date of the First Commercial Sale of the [**] Licensed Product in the Recepta Territory until the expiration of the Royalty Term in the Recepta Territory. Such royalty payments shall be calculated based on year-to-date Recepta Annual Net Sales in the Recepta Territory, applying the tiered royalty rates shown below:


Recepta Annual Net Sales						Royalty Rate
[**]						[**]
[**]						[**]

For avoidance of doubt, the following example shall illustrate the royalty payment calculation: Royalties on aggregate Net Sales in the Recepta Territory in a calendar year shall be paid at the rate applicable to the portion of Net Sales within each of the Net Sales levels during such calendar year. For example, if, during a calendar year, aggregate Net Sales in the Recepta Territory were equal to [**], then the royalties payable would be calculated by adding (i) the royalties with respect to the first [**] at the first-level percentage of [**]; and (ii) the royalties with respect to the next [**] at the second-level percentage of [**], for a total royalty of [**].

5.6 Combination Products. If a Licensed Product under this Agreement is sold in form of a Combination Product, then Net Sales for such Combination Product shall be determined on a [**] as follows:

5.6.1 If the Licensed Product and the Other Product are sold separately, the royalty payments due on the Net Sales of the Combination Product shall be equal to the applicable percentage (royalty rate) multiplied by the Net Sales of the Combination Product multiplied by the fraction, A/(A+B) where “A” is the mean gross selling price of the Licensed Product and “B” is the mean gross selling price of the Other Product.

5.6.2 If the Licensed Product and the Other Product are sold separately, but the mean gross selling price of the Other Product cannot be determined, the royalty payments due on the Net Sales of the Combination Product shall be equal to the applicable percentage (royalty rate) multiplied by the Net Sales of the Combination Product multiplied by the fraction A/C wherein “A” is the mean gross selling price of the Licensed Product and “C” is the mean gross selling price of the Combination Product.

5.6.3 If the Licensed Product and the Other Product are sold separately, but the mean gross selling price of the Licensed Product cannot be determined, the royalty payments due on the Net Sales of the Combination Product shall be equal to the applicable percentage (royalty rate) multiplied by the Net Sales of the Combination Product multiplied by the following formula: one (1) minus B/C wherein “B” is the mean gross selling price of the Other Product and “C” is the mean gross selling price of the Combination Product.

5.6.4 If the Licensed Product and the Other Product are sold separately, but the mean gross selling price of neither the Licensed Product nor the Other Product can be determined, Net Sales of the Licensed Product shall be equal to Net Sales of the Combination Product multiplied by a percentage agreed to by the Parties, acting in good faith. If the Parties are unable to agree upon such a percentage, the dispute shall be resolved by arbitration pursuant to Section 11.7.

5.7 Bundling. In the event a Licensed Product is “bundled” for sale together with one or more other products in a country (a “Product Bundle”), then Net Sales for such Licensed Product may be discounted by no more than the [**] of all products in a particular Product Bundle sold in such country calculated as [**].

5.8 Loss of Patent Coverage.

5.8.1 With respect to any country outside the Recepta Territory, if the manufacture, use, importation, offering for sale or sale of any Licensed Products in such country is Covered as of the date of the First Commercial Sale in such country, or becomes Covered thereafter, by a Valid Claim of at least one Recepta Patent and the manufacture, use, importation, offering for sale or sale of such Licensed Product in such country subsequently ceases to be Covered by a Valid Claim of at least one Recepta Patent, then, for the remaining period of the Royalty Term applicable to such Licensed Product in such country, the Net Sales of such Licensed Product in such country to be included in the Mersana Annual Net Sales for the purpose of the calculation of the royalties due under Section 5.4.1 shall be reduced by [**]. With respect to any country outside the Recepta Territory, if the manufacture, use, importation, offering for sale or sale of any Licensed Products in such country is not Covered by a Valid Claim of at least one Recepta Patent as of the date of the First Commercial Sale in such country, the Net Sales of such Licensed Product in such country to be included in the Mersana Annual Net Sales for the purpose of the calculation of the royalties due under Section 5.4.1 shall be reduced by [**]; provided, however, that such reduction shall not apply to any Net Sales in such country that are received by Mersana after such time, if any, during the Royalty Term applicable

to such Licensed Product, as such Licensed Product becomes Covered by a Valid Claim of at least one Recepta Patent in such country, and continues to be Covered by at least one such Valid Claim. The Parties hereby acknowledge and agree that royalties that are payable by Xxxxxxx for a Licensed Product for which no Patents exist shall be in consideration of (i) Recepta’s expertise and know-how concerning its Development of the Recepta Know-How and (ii) the licenses granted to Mersana hereunder with respect to Recepta Know-How that are not within the claims of any Recepta Patents.

5.8.2 With respect to the Recepta Territory, if the manufacture, use, importation, offering for sale or sale of any Licensed Products in such territory is Covered as of the date of the First Commercial Sale in such territory, or becomes Covered thereafter, by a Valid Claim of at least one Mersana Patent and the manufacture, use importation, offering for sale or sale of such Licensed Product in such territory subsequently ceases to be Covered by a Valid Claim of at least one Mersana Patent, then for the remaining period of the Royalty Term applicable to such Licensed Product in such territory, the Net Sales of such Licensed Product in such territory to be included in the Recepta Annual Net Sales for the purpose of calculation of the royalties due under Section 5.5 shall be reduced by [**]. With respect to the Recepta Territory, if the manufacture, use, importation, offering for sale or sale of any Licensed Products in such country is not Covered by a Valid Claim of at least one Mersana Patent as of the date of the First Commercial Sale in such territory, the Net Sales of such Licensed Product in such territory to be included in the Recepta Annual Net Sales for the purpose of the calculation of the royalties due under Section 5.5 shall be reduced by [**]; provided, however, that such reduction shall not apply to any Net Sales in such territory that are received by Recepta after such time, if any, during the Royalty Term applicable to such Licensed Product, as such Licensed Product becomes Covered by a Valid Claim of at least one Mersana Patent in such territory, and continues to be Covered by at least one such Valid Claim. The Parties hereby acknowledge and agree that royalties that are payable by Recepta for a Licensed Product for which no Patents exist shall be in consideration of (i) Xxxxxxx’s expertise and know-how concerning its Development of the Mersana Know-How and (ii) the licenses granted to Recepta hereunder with respect to Mersana Know-How that are not within the claims of any Mersana Patents.

5.9 Payment Terms. Each Party shall make all royalty payments owed under this Agreement within [**] Business Days following the end of each calendar quarter for Net Sales from the previous calendar quarter, and together with such payment, shall submit to the other Party a written report setting forth (i) a reasonably detailed calculation of the Net Sales for such calendar quarter in each country in its respective territory upon which such royalty payments are based including all deductions from gross sales made in arriving at the same, (ii) year-to-date, total royalty payments due to the other Party in respect of Licensed Products and Combination Products, and (iii) any other information needed to support the calculation of such Net Sales and royalty payments. All sums due under this Agreement shall be payable in United States dollars by bank wire transfer in immediately available funds to such bank account(s) as the applicable payee shall designate.

5.10 Currency. When Licensed Products are sold for monies other than United States dollars, the Net Sales of such Licensed Products will first be determined in the foreign currency of the country in which such Licensed Products were sold and then converted into equivalent United States funds. The exchange rate will be the applicable rate published by the Wall Street Journal on the last Business Day of the calendar quarter in which such royalties accrued.

5.11 Tax Withholding, Financial Records and Audits.

5.11.1 Tax Withholding. If Applicable Law requires either Party to withhold any taxes from payments made to the other Party under this Agreement, then such taxes

shall be deducted by the withholding Party as required by and shall be paid by the withholding Party to the proper tax authorities. Official receipts of payment of any withholding tax shall be secured and sent to Party whose payments were subject to withholding as evidence of such payment. The Parties shall exercise their best efforts to ensure that any withholding taxes imposed are reduced as far as possible under the provisions of any relevant tax treaty. The Parties agree that Recepta is transferring substantially all of its rights in the Recepta Technology for the Field and, as such, agree to treat such transfer as a sale (versus a license) for U.S. Federal tax purposes. Accordingly, Xxxxxxx agrees that no U.S. withholding shall be made with respect to the upfront payment to be paid by Mersana pursuant to Section 5.1 or any of the milestone payments to be paid by Xxxxxxx pursuant to Sections 5.2 or 5.3. However, if any relevant Governmental Authority or any change in Applicable Law requires Mersana to make such withholdings or to remit any amounts which were required to have been withheld in respect of any previous payments to Recepta hereunder, Xxxxxxx shall notify Recepta promptly in writing and Mersana may make such withholdings and may remit such amounts. Recepta shall indemnify Mersana for any withholding amounts it is required to remit to the applicable Governmental Authority in respect of such previous payments to Recepta, together with any fines or penalties incurred solely as a result of Xxxxxxx’s failure to make such withholding.

5.11.2 Financial Records and Audits. Each Party shall keep accurate and complete records of all financial information needed to calculate Net Sales and/or any payments due to such Party under this Agreement. Each Party shall retain all records relating to Net Sales and/or any payments made to such Party during the [**] preceding calendar years. During the Royalty Term applicable to a Party and for [**] thereafter, at the other Party’s written request, such records shall be made available for inspection, review and audit, during normal business hours and with reasonable advance notice to the audited Party, by an independent certified public accountant appointed by the auditing Party and reasonably acceptable to the audited Party for the purpose of verifying the accuracy of the audited Party’s reports and payments related to or based on Net Sales pursuant to this Agreement and reporting to the auditing Party the findings (but not the underlying data) of said examination of records as are necessary to evidence whether or not the audited Party has complied with its payment and other financial obligations related to or based on Net Sales under this Article 5 and the extent of any inaccuracy bearing on a Party’s payment obligations hereunder. A copy of any report provided to the auditing Party by the accountant shall be given concurrently to the audited Party. The auditing Party may perform such an audit no more than [**]. The auditing Party shall be responsible for all costs and expenses incurred in performing any such audit unless the audit discloses at least a [**] shortfall, in which case the audited Party shall bear the full cost of the audit. If any such examination reveals an underpayment of royalties or that any Commercialization milestone payment contemplated in Section 5.3 was achieved by the corresponding milestone payment was not paid, then the audited Party shall promptly, and in any event within [**] Business Days following delivery of such audit report, pay the amount of the underpayment or the unpaid milestone payment to the other Party, together with interest on the amount owing calculated at a rate of [**] per annum form the date on which the amount owing was to be paid until the date of payment in full. If said examination of records reveals any overpayment of royalties, then the auditing Party shall credit the amount overpaid against the audited Party’s future royalty payment(s). Notwithstanding the foregoing, if the audited Party disputes the findings of such examination in good faith, the audited Party may notify the auditing Party in writing and the matter shall be resolved in accordance with the dispute resolution procedure set forth in Section 11.7. The time for making any relevant payments due under this Section 5.11.2 shall be tolled during the pendency of any such dispute resolution, provided, that interest on any amount determined to be owing shall in any event accrue from the date on which such amount was to be paid.

6. CONFIDENTIAL INFORMATION AND PROPRIETARY RIGHTS.

6.1 Definition. “Confidential Information” means confidential or proprietary information, data or know-how, whether provided in written, oral, visual or other form, provided by one Party (the “Disclosing Party”) to the other Party (the “Receiving Party”) in connection with this Agreement, including, but not limited to, the terms of this Agreement and information relating to the Disclosing Party’s existing or proposed research, development efforts, patent applications, business or products. Confidential Information shall not include any such information that: (i) is already known to the Receiving Party or its Affiliates (other than under an obligation of confidentiality) at the time of disclosure (as evidenced by written records of the Receiving Party); (ii) is or becomes generally available to the public other than through any act or omission of the Receiving Party or its Affiliates; (iii) is disclosed to the Receiving Party or its Affiliates by a Third Party who, to the Receiving Party’s knowledge, had no separate nondisclosure obligation in respect of such information; or (iv) is independently discovered or developed by or on behalf of the Receiving Party or its Affiliates without the use of the Confidential Information of the Disclosing Party (as evidenced by written records of the Receiving Party). The terms of this Agreement shall be deemed Confidential Information of each Party.

6.2 Confidentiality. The Receiving Party shall keep in confidence all Confidential Information of the Disclosing Party with the same degree of care it employs to maintain the confidentiality of its own Confidential Information, but no less than a reasonable degree of care. The Receiving Party shall not use such Confidential Information for any purpose other than in performance of this Agreement or the exercise of its rights hereunder, or disclose the same to any other Person other than to such of its own and its Affiliates’ employees, agents, sublicensees and subcontractors who have a need to know such Confidential Information in connection with such permitted use. A Receiving Party shall advise any employee, agent, sublicensee or subcontractor who receives Confidential Information of such obligations, and the Receiving Party shall ensure (through enforcement of written agreements or otherwise) that all such employees, agents, sublicensees and subcontractors comply with such obligations as if they had been a Party hereto. The Receiving Party will be liable for breach of this Article 6 by any of its employees, agents, sublicensees and subcontractors.

6.3 Permitted Disclosure and Use. The Receiving Party shall have the right to disclose Confidential Information if, (i) in the reasonable opinion of the Receiving Party’s legal counsel, such disclosure is required by any Applicable Laws (including the rules of any stock exchange), provided that, to the extent permitted pursuant to Applicable Law, the Receiving Party gives adequate prior notice of such disclosure to the Disclosing Party and the Receiving Party seeks confidential treatment of such Confidential Information to the maximum extent permitted by the relevant Governmental Authority; or (ii) a court, tribunal, administrative agency or other Governmental Authority orders such disclosure, provided that, to the extent permitted pursuant to Applicable Law, the Receiving Party gives adequate prior notice of such disclosure to the Disclosing Party to permit the Disclosing Party to intervene and to request protective orders or other confidential treatment. The Receiving Party will cooperate reasonably with any such efforts by the Disclosing Party. Furthermore, notwithstanding any other provision of this Agreement, either Party may disclose Confidential Information as necessary in connection with any actual or proposed financing, acquisition, merger, collaboration, licensing transaction or similar transaction, subject to confidentiality, or as necessary to obtain legal or financial advice from its attorneys, accountants and legal or financial advisors, provided, however, that the applicable Party shall limit such disclosure to the extent possible including the provision of redacted documents and provided further that the Person to whom such disclosure is made is subject to obligations of confidentiality to the Party making such disclosure that are no less stringent than those contained in this Article 6. The Receiving Party making any disclosure pursuant to the immediately preceding sentence will be responsible for the compliance by such

Persons with the requirements of this Article 6 as though such Persons were the Receiving Party hereunder and shall be liable for any breach by such Persons of this Article 6. The Parties shall also be permitted to make disclosures consistent with, and pursuant to, Sections 11.1 and 11.2.

6.4 Return. Upon termination of this Agreement, the Receiving Party shall return or destroy all documents or other media containing Confidential Information of the Disclosing Party with the exception of one (1) copy for the sole purpose of monitoring and documenting the confidentiality obligations hereunder.

6.5 Remedies. Money damages will not be an adequate remedy if this Article 6 is breached and, therefore, either Party may, in addition to any other legal or equitable remedies, seek an injunction or other equitable relief against such breach or threatened breach without the necessity of posting any bond or surety.

6.6 Survival. This Article 6 shall survive the expiration or termination of this Agreement for a period of [**] years.

7.2.1 as of the Effective Date, (i) Recepta has not previously assigned, transferred, licensed, conveyed or otherwise encumbered its right, title and interest in the

Recepta Patents or any component of the Recepta Know-How in a manner that precludes or is inconsistent with the license rights granted to Mersana pursuant to this Agreement, (ii) there are no Patents owned or Controlled by Recepta, other than the Recepta Patents, that would prevent Mersana or its sublicensees from Developing, manufacturing and/or Commercializing Licensed Products as set forth herein, and from exploiting the rights granted under Section 2.1.1, (iii) there are no pending claims, judgments or settlements affecting any of the Recepta Technology owned by Recepta and Recepta has received no written notice thereof, (iv) to Recepta’s knowledge, there are no pending claims, judgments or settlements affecting any of the Recepta Technology otherwise Controlled by Recepta and Recepta has received no written notice thereof, and (v) to Recepta’s knowledge, none of the foregoing contemplated by clauses (iii) or (iv) above is threatened;

8.3 Procedure for Indemnification.

8.3.1 Notice. Each Party (“Indemnified Party”) will notify promptly the other Party (“Indemnifying Party”) in writing if it becomes aware of a Claim (actual or potential) by any Third Party or any proceeding commenced by a Third Party (including any investigation by a Governmental Authority) (any of the foregoing, a “Third Party Claim”) for which indemnification may be sought and will give such related information as the Indemnifying Party shall reasonably request; provided, however, that no failure or delay in giving such notice shall limit the Indemnified Party’s right to indemnification hereunder except to the extent that the Indemnifying Party is prejudiced thereby.

8.3.2 Defense of Claim. The Indemnifying Party shall defend or control the defense of Third Party Claims. The Indemnifying Party shall be responsible for satisfying and discharging any award made to or settlement reached with the Third Party pursuant to the terms of this Agreement. The Indemnifying Party shall retain counsel reasonably acceptable to the Indemnified Party (such acceptance not to be unreasonably withheld, refused, conditioned or delayed) to represent the Indemnified Party and shall pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, the Indemnified Party shall have the right to participate in, but not control, the defense of such proceeding at its own cost and expense, and shall have the right to retain its own counsel, at its own cost and expense. Neither Party shall settle any Third Party Claim without the prior written consent of the other Party, which consent shall not be unreasonably withheld, refused, conditioned or delayed. The Indemnified Party shall cooperate in all reasonable respects in the defense of such Third Party Claim, as requested by the Indemnifying Party. The Indemnifying Party shall not, without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, refused, conditioned or delayed), effect any settlement of any such Third Party Claim, unless such settlement includes an unconditional release of the Indemnified Party from all liability on such Claims. Notwithstanding the foregoing, if the Indemnifying Party notifies the Indemnified Party in writing that it does not intend to assume the defense of any Third Party Claim subject to indemnification hereunder in accordance with the foregoing or fails to assume the defense of any Third Party Claim at least [**] Business Days before any deadline the passing of which could adversely affect the outcome without responsive action by or on behalf of the Indemnified Party (or, if the Indemnifying Party receives less than [**] Business Days’ notice of such deadline, if it fails to assume such defense as soon as practicable following receipt of notice), the Indemnified Party shall have the right to assume and control such defense and shall have the right to settle or compromise the same without the Indemnifying Party’s consent, and the fees and expenses incurred by the Indemnified Party in connection therewith, including its reasonable legal fees and expenses, will be included in the indemnifiable Losses in connection with such Third Party Claim.

8.4 Insurance. During the Term of this Agreement, the Parties shall obtain and maintain at their sole cost and expense, an adequate liability insurance or self-insurance program (including product liability insurance) to protect against potential liabilities and risk arising out of the Development, manufacture and Commercialization of any Licensed Product and upon such terms (including coverages, deductible limits and self-insured retentions) as are customary in the biopharmaceutical industry in such Party’s territory. The Party maintaining any such Third Party insurance coverage shall ensure that the other Party is named as an additional insured thereunder and shall provide a certificate evidencing such coverage to the other Party upon request.

9. PATENTS.

9.1 Prosecution and Maintenance.

9.1.1 Recepta Patents. For so long as the license grants to Mersana set forth in Section 2.1.1 remain in effect, Recepta shall use reasonable efforts to, or, to the extent LICR has the right to conduct the following activities pursuant to the LICR License, shall use reasonable efforts to cause LICR to file, prosecute and maintain the Recepta Patents in such jurisdictions within the Territory as Mersana may specify in writing. Recepta shall keep, or, as applicable, shall cause LICR to keep, Mersana reasonably informed of the progress with regard thereto, and shall promptly provide, or, as applicable, shall cause LICR to provide, Mersana with all material correspondence, filings, notifications and other communications, relating to the preparation, filing, prosecution and maintenance of such Recepta Patents in the Territory. Xxxxxxx shall have the right to comment on the preparation, filing, prosecution and maintenance of the Recepta Patents in the Territory and Recepta, as applicable, shall provide Xxxxxxx’s comments to LICR; provided, however, that LICR or Recepta, as applicable, shall make the final determination with respect thereto after considering any such comments in good faith. Mersana will reimburse Recepta’s out-of-pocket costs and expenses incurred after the Effective Date in connection with any of Recepta’s contractual obligations to LICR relating to the LICR’s prosecution and maintenance of the Recepta Patents in the Territory or, if mutually agreed in writing by the Parties and LICR, directly pay the relevant costs and expenses to LICR.

9.1.2 Mersana Patents. As between the Parties, Xxxxxxx is solely responsible for the filing, prosecution and maintenance of the Mersana Patents. For so long as the license grants to Recepta set forth in Section 2.1.2 remain in effect, Mersana shall use reasonable efforts to file, prosecute and maintain the Mersana Patents in the Recepta Territory. Recepta shall provide Xxxxxxx, at Xxxxxxx’s sole cost and expense, all reasonably requested assistance in connection therewith. Xxxxxxx shall keep Recepta informed of all material issues and developments relating to the preparation, filing, prosecution and maintenance of such Mersana Patents in the Recepta Territory. Without limiting the foregoing, Xxxxxxx will provide Recepta with copies of all material correspondence, filings, notifications and other correspondence with the Brazilian National Institute of Industrial Property relating to the preparation, filing and maintenance of the Mersana Product Patents in the Recepta Territory and shall consider in good faith any comments that Recepta may have in relation thereto. In the event that (i) Xxxxxxx intends not to prosecute or maintain any Mersana Product Patent in the Recepta Territory or (ii) Mersana intends to abandon or otherwise cause or allow any Mersana Product Patent to be forfeited, and, in either case, one or more Valid Claims of such Patent Cover a Licensed Product in the Recepta Territory, then Mersana shall provide timely written notice to Recepta of such intention.

9.2 Notice of Patent Challenge. Each Party shall promptly, but in any event no later than [**] Business Days after receipt of notice of such action, notify the other Party in writing upon becoming aware of any re-examination, interference, opposition, nullity or similar actions, or challenges to the validity or enforceability of, or any alleged or threatened infringement by any Third Party of, either (i) the Recepta Patents in the Territory or (ii) the Mersana Patents in the Recepta Territory, in each case, with respect to the Field, or if such Party or any of their respective Affiliates or sublicensees shall be individually named as a defendant in

a legal proceeding in the Territory by a Third Party alleging infringement or violation of such Third Party’s Patents (any of the foregoing occurrences, a “Patent Challenge”).

9.3 Patent Challenge Regarding Mersana Patents. As between the Parties, to the extent a Patent Challenge directly concerns any Mersana Patents in the Recepta Territory, Xxxxxxx shall have the first right, but not the obligation, to respond to, defend or prosecute any

such Patent Challenge, including defending against any counter-claims of invalidity and unenforceability with respect to such Patents. If Xxxxxxx elects to pursue any such Patent Challenge, Xxxxxxx will be solely responsible for, and will have the full control of, the proceedings. In making its determination whether to take any action to prosecute any Patent Challenge involving any alleged or threatened infringement of the Mersana Patents in the Recepta Territory, Xxxxxxx may take into account the potential effect such action could have on the entirety of Xxxxxxx’s patent portfolio and not solely the Mersana Patents in the Recepta Territory. If a Patent Challenge involves a Third Party claim of infringement against Recepta or its Affiliates or sublicensees involving the use, marketing or sale of the Licensed Products in the Recepta Territory and Mersana elects not to exercise its right to defend them against such an allegation, then Recepta may defend such Third Party Claim at its own expense and Mersana shall cooperate with Recepta at Recepta’s request and expense and shall have the right to be represented by counsel selected by Xxxxxxx. In connection with any Patent Challenge relating to the Mersana Patents in the Recepta Territory: (i) the Party not responsible for the Patent Challenge will cooperate with the other Party (“Responsible Party”) and its legal counsel, join in such suits as may be brought by the Responsible Party, and be available at the Responsible Party’s reasonable request to be an expert witness or otherwise to assist in such proceedings at the Responsible Party’s expense; (ii) the Responsible Party will keep the other Party and its counsel reasonably informed at all times as to the status of the Responsible Party’s response or defense; (iii) legal fees and other costs and expenses of the Responsible Party associated with such response or defense shall be paid by the Responsible Party; (iv) legal fees and other costs and expenses associated with such response or defense incurred by the other Party at the Responsible Party’s request shall be paid by the Responsible Party; and (v) any amounts recovered from Third Parties in connection with any such Patent Challenge shall be applied [**] to Recepta and [**] to Mersana, subject first to reimbursement of expenses of the Responsible Party.

9.4 Patent Challenge Regarding Recepta Patents.

9.4.1 As between the Parties, to the extent a Patent Challenge directly concerns the Recepta Patents in the Territory, Xxxxxxx shall have the first right, but not the obligation, to respond to, defend or prosecute any such Patent Challenge, including defending against any counterclaims of invalidity and unenforceability with respect to such Patents. In the event Mersana elects to do so, it will be solely responsible for and have the full control of the proceedings. In connection therewith: (i) Recepta will cooperate with Xxxxxxx and its legal counsel, join in such suits as may be brought by Xxxxxxx, and be available at Mersana’s reasonable request to be an expert witness or otherwise to assist in such proceedings at Xxxxxxx’s expense; (ii) Mersana will keep Recepta and its counsel reasonably informed at all times as to the status of Mersana’s response or defense and Recepta shall have the right to participate in, but not control, any such proceeding with its own counsel at Recepta’s sole cost and expense (except as provided in clause (iv) below); (iii) legal fees and other costs and expenses of Mersana, associated with such response or defense shall be paid by Xxxxxxx; (iv) legal fees and other costs and expenses associated with such response or defense incurred by Recepta at Xxxxxxx’s request shall be paid by Xxxxxxx; and (v) any amounts recovered from Third Parties in connection with such response or defense shall be applied [**] to Recepta and [**] to Mersana, subject first to reimbursement of expenses of Mersana.

9.4.2 In the event that Xxxxxxx elects not to respond to, defend or prosecute any Patent Challenge that directly concerns the Recepta Patents in the Recepta Territory, or Mersana elects to abandon any such action, Mersana shall promptly notify Recepta of such election in writing. In such event, Recepta shall have the option to respond, defend or prosecute such Patent Challenge at Recepta’s sole cost and expense, provided that Mersana shall cooperate with and provide assistance to Recepta at Recepta’s expense, including by allowing Recepta to initiate or continue any such action in Xxxxxxx’s name. Recepta shall keep Xxxxxxx

informed of the status of such Patent Challenge and notify it promptly in writing of any judgment, settlement or other disposition thereof. If any amounts are recovered from any Third Party in connection with any such Patent Challenge which Recepta responds to, defends or prosecutes pursuant to this Section 9.4.2, Recepta shall first deduct its expenses from the amount of such recovery and then promptly pay Mersana an amount equal to the [**] of the remaining recovery amount.

9.5 Defense of Infringement Claims. The Party responsible for managing the defense against any Third Party claim of Patent infringement pursuant to Sections 9.3 or 9.4, as applicable, shall have the right to settle such claim on terms deemed appropriate by such Party, provided, however, that any such settlement must include a full and unconditional release from all liability of the other Party and may not adversely affect the rights of the other Party without such other Party’s prior written consent (such consent not to be unreasonably withheld or delayed).

9.6 Biosimilars. Each Party shall promptly, but in any event no later than [**] Business Days after receipt of notice of such application, notify the other Party if it becomes aware of any application for regulatory approval of a biosimilar anywhere in the Territory where any Licensed Product is a reference product under such application. Mersana shall take the lead and be responsible for preparing and filing any responses with any Regulatory Authority and negotiating any patent resolution in connection with any such application as set forth in paragraphs 2 through 6 of Section 351(l) of the United States Public Health Service Act (42 U.S.C. § 262(l)(2)-(6)), or any foreign equivalent thereof and shall use Diligent Efforts in relation thereto. Recepta shall cooperate with Xxxxxxx’s reasonable requests for assistance in connection therewith.

10. TERM AND TERMINATION.

10.1 Term. This Agreement shall come into effect on the Effective Date and continue until it is terminated in its entirety by either Party pursuant to Section 10.2 (such period, the “Term”). Effective upon the expiration of the Royalty Term for a Licensed Product with respect to any country outside the Recepta Territory, the license granted to Mersana pursuant to Section 2.1.1 with respect to such Licensed Product in such country shall automatically become fully paid-up and royalty-free. Effective upon the expiration of the Royalty Term in the Recepta Territory for a Licensed Product, the license granted to Recepta pursuant to Section 2.1.2 with respect to such Licensed Product shall automatically become fully paid-up and royalty-free.

10.2 Termination.

10.2.1 Convenience. Mersana may terminate this Agreement, in its entirety or a country-by-country, Licensed Product-by-Licensed Product basis with or without cause at any time by giving Recepta at least one hundred eighty (180) calendar days’ prior written notice (if terminating this Agreement in its entirety) or forty-five (45) calendar days’ prior written notice (if terminating this Agreement with respect to one or more countries); provided, however, that Mersana may not terminate this Agreement for convenience with respect to the Recepta Territory unless such termination is in connection with a termination of this Agreement in its entirety.

10.2.2 Material Breach.

(a) In the event of a material breach of this Agreement, the non-breaching Party may deliver notice of such breach to the breaching Party, such notice containing the material details of said breach to the extent known to the non-breaching Party. The breaching Party shall have, subject to Section 10.2.2(b), [**] Business Days to cure such breach [**]

Business Days in the case of a Party’s breach of its payment obligations). Subject to Section 10.2.2(b), if the Party receiving notice of breach fails to cure such breach within the [**] Business Day period or [**] Business Day period (as applicable), the Party originally delivering the notice may terminate this Agreement upon written notice to the other Party, provided, that if the breach applies only to a given country, the non-breaching Party may only terminate this Agreement with respect to such country and thereafter, in the case of a breach by Xxxxxxx, the Territory shall no longer include the country in which such termination has occurred.

(b) If a Party gives notice of breach under Section 10.2.2(a) and the other Party, acting in good faith, disputes in writing prior to the end of the applicable cure period whether such notice was proper, then the issue of whether a material breach has occurred shall be resolved in accordance with Section 11.7. If as a result of such dispute resolution process it is determined that the notice of breach was proper, then such notice shall be deemed to have been effective if the breaching Party fails thereafter to cure such breach in accordance with the determination made in the resolution process within the applicable cure period following such determination. If as a result of such dispute resolution process it is determined that the notice of breach was improper, then no such notice shall be deemed to have been effective and this Agreement shall remained in effect. All of the terms and conditions of this Agreement shall remain in full force and effect during the pendency of such dispute resolution process.

10.2.3 Bankruptcy. Either Party may terminate this Agreement in its entirety immediately upon written notice, if the other Party makes an assignment for the benefit of creditors, or a receiver, trustee in bankruptcy or similar officer is appointed to take charge of any or all of the other Party’s property, or the other Party seeks protection under any bankruptcy, receivership, trust deed, creditors arrangement, composition or comparable proceeding or such a proceeding is instituted against the other Party and is not dismissed within [**] Business Days, or the other Party becomes insolvent or, without a successor, dissolves or liquidates.

In the event that this Agreement is terminated by Recepta pursuant to the terms of this Agreement or by Mersana pursuant to Section 10.2.1, (i) all rights and licenses on a [**] basis granted to Mersana, as well as all sublicenses granted under this Agreement by Mersana and/or any of its sublicensees, shall immediately terminate; however, Mersana and its sublicensees shall be entitled to sell, for a period of [**] months after the effective date of termination, any inventories of Licensed Products in the Field in the Territory that are on-hand as of the effective date of termination, subject to Mersana’s payment of royalties to Recepta in respect of such sales, in accordance with Article 5 hereof and (ii) except as otherwise contemplated in Section 10.3.2(a), all of the rights and licenses granted to Recepta under Sections 2.1.2, 2.2.2, 2.3.3 and 2.4.2, including any sublicenses already granted by Recepta pursuant to Section 2.2.2, shall remain in effect, subject to Recepta’s ongoing obligations to make royalty payments in accordance with Sections 5.5 through 5.7 and subject to Section 5.8.2 which, for clarity, shall also remain in effect. In addition, Recepta may, at its option, offset any amounts due and payable to Mersana in

respect of the aforementioned royalties by the amount of any damages awarded to Recepta by the arbitrator pursuant to Section 11.7.

10.3.2 Termination by Xxxxxxx.

(a) In the event that this Agreement is terminated by Mersana either (i) in respect to the Recepta Territory pursuant to Sections 10.2.2, 10.2.3 or 10.2.4(b) or (ii) in its entirety pursuant to Section 10.2.1 and following such termination no sales of any Licensed Product by or for Recepta or Mersana or any of their respective Affiliates or sublicensees have been made for [**] month period (the last day of such period, the “Cessation Date”), then (1) all rights and licenses granted to Recepta in respect of the Mersana Technology, Promotional Materials and ROW Trademarks, as well as all sublicenses granted under this Agreement by Recepta and/or any of its sublicensees in respect of the foregoing, shall immediately terminate in respect of all Licensed Products as of the effective date of termination (in the case of a termination contemplated by the foregoing clause (i)) or as of the Cessation Date (in the case of a termination contemplated by the foregoing clause (ii)), (2) following the effective date of termination (in the case of a termination contemplated by the foregoing clause (i)) or following the Cessation Date (in the case of a termination contemplated by the foregoing clause (ii)), if requested by Xxxxxxx, at its option, Recepta will either (x) in the case of a termination contemplated by the foregoing clause (i), promptly assign or transfer, or cause to be assigned and transferred to Mersana (or if not so assignable, Recepta shall use reasonable efforts to make available to Mersana the benefits of), all Regulatory Approvals specifically relating to all Licensed Products in the Recepta Territory, together with all related filings with any Regulatory Authority and any other supporting documentation and dossier submissions in respect of such Licensed Products or (y) in the case of a termination contemplated by the foregoing clause (ii), promptly withdraw or otherwise terminate the effectiveness of all Regulatory Approvals specifically relating to all Licensed Products in the Recepta Territory and transfer to Mersana all related filings with any Regulatory Authority and any other supporting documentation and dossier submissions in respect of such Licensed Products, and (3) following the effective date of termination (in the case of a termination contemplated by the foregoing clause (i)) or following the Cessation Date (in the case of a termination contemplated by the foregoing clause (ii)), if requested by Xxxxxxx, Recepta shall promptly cause all of Recepta’s rights, title and interest in and to the Recepta Trademarks (other than any corporate names or logos) and Promotional Materials (including all translations thereof) specifically relating to the Licensed Products in the Recepta Territory to be transferred and assigned solely and exclusively to Mersana or Xxxxxxx’s designee and use reasonable efforts to take such further action as Mersana determines is reasonably necessary for ownership and Control thereof to vest solely and exclusively in Mersana or Xxxxxxx’s designee(s). In the case of a termination by Xxxxxxx pursuant to Section 10.2.2 or 10.2.4(b), such transfers and other actions contemplated by the immediately preceding sentence shall be at Recepta’s sole cost. Otherwise, Xxxxxxx shall promptly reimburse Recepta for all of the direct, out-of-pocket costs and expenses incurred by Recepta (x) in connection with obtaining any Regulatory Approvals which Xxxxxxx requests to have withdrawn or terminated pursuant to the foregoing clause (2), including all fees paid by Recepta to any Regulatory Authority in connection with any application for Regulatory Approval with respect to any Licensed Product in the Recepta Territory and (y) in connection with obtaining or maintaining any Recepta Trademarks or Promotional Materials which Mersana requests to have assigned or transferred to it pursuant to the foregoing clause (3). For clarity, Xxxxxxx shall not be obligated to reimburse Recepta pursuant to this Section 10.3.2(a) for (A) any other costs or expenses of Recepta incurred in connection with any Development activities undertaken by Recepta, or undertaken by Xxxxxxx and reimbursed by Recepta, in relation thereto, (B) any fees associated with actually effecting any such transfers of filings, approvals, trademarks or rights, or (C) any associated legal fees or expenses.

(b) In the event of any termination of this Agreement by Mersana pursuant to Sections 10.2.2, 10.2.3, or 10.2.4(b), all of the rights and licenses granted to Mersana under Sections 2.1.1 and 2.2.1, including any sublicenses already granted by Mersana pursuant to Section 2.2.1, shall remain in effect, subject to Mersana’s ongoing obligations to make the milestone and royalty payments in accordance with Sections 5.2, 5.3, 5.4, 5.6 and 5.7 and subject to Section 5.8.1, all of which, for clarity, shall also remain in effect; provided, however, that to the extent Mersana is obligated to pay any such milestone and/or royalty payments directly to LICR pursuant to the terms of the Three-Party Agreement, Mersana shall make such payments directly to LICR in accordance with such terms and Mersana shall not have any further obligation hereunder or otherwise to make such payments to Recepta. In addition, Mersana may, at its option, offset any amounts due and payable to Recepta in respect of the aforementioned milestones and royalties by the amount of any damages awarded to Mersana by the arbitrator pursuant to Section 11.7.

10.3.3 Partial Termination. For the avoidance of doubt, if Recepta exercises its right to terminate this Agreement pursuant to Section 10.2.2 or Section 10.2.4(a) due to Mersana’s breach of this Agreement or challenge to Recepta’s Patents, or Mersana terminates this Agreement pursuant to Section 10.2.1, in respect of one or more (but not all) countries in the Territory, this Agreement shall terminate only with respect to those specific country(ies) such that, thereafter, the Territory shall no longer include the country in which such termination has occurred.

10.3.4 Continued Supply Rights.

(a) If this Agreement terminates in its entirety or in respect of any Licensed Product(s) in respect of which Regulatory Approval has been received in the Recepta Territory, other than pursuant to a termination by Mersana pursuant to Sections 10.2.2, 10.2.3, or 10.2.4(b), and one or more of the Licensed Product(s) affected by such termination will not be manufactured by or for Mersana or its Affiliates or sublicensees for Commercialization anywhere outside the Recepta Territory following such termination, then (i) Mersana shall discuss in good faith with Recepta the terms under which it might continue to supply Recepta or its designated sublicensee with such Licensed Product(s) for sale to end user customers in the Recepta Territory, on terms as close as reasonably possible to those contemplated by Section 3.3.2, it being understood that (a) Mersana may not Control all of the intellectual property rights necessary to manufacture the Licensed Products and shall have no obligation to develop or acquire any intellectual property rights in order to arrange for such manufacture and (b) in no event shall Mersana be required, as a condition of such supply arrangement, to transfer or otherwise disclose (or to authorize the transfer or disclosure of) any Mersana Technology to a Third Party not already in possession of such Mersana Technology. Such discussions shall begin on the date Mersana or Recepta, as applicable, gives effective notice of termination and, unless the Parties agree otherwise or a supply arrangement is sooner agreed to in writing, shall end on the effective date of termination if Mersana is the terminating Party or [**] calendar days after the effective date of termination if Recepta is the terminating Party. In addition, following any such termination, Mersana shall use reasonable efforts to supply, or cause to be supplied, to Recepta or its designated sublicensee, for a purchase price equal to Mersana’s cost, a quantity of Licensed Product equal to Recepta’s (or such sublicensee’s) forecasted requirements for the [**] period following the effective date of such termination.

(b) If this Agreement terminates in its entirety or in respect of any Licensed Product(s) in respect of which Regulatory Approval has been received in the Recepta Territory, other than pursuant to a termination by Mersana pursuant to Sections 10.2.2, 10.2.3, or 10.2.4(b), and one or more of the Licensed Product(s) affected by such termination will continue to be manufactured by or for Mersana or its Affiliates or sublicensees for Commercialization anywhere outside the Recepta Territory following such termination, then Recepta shall be entitled to continue to receive supply of such Licensed Product(s) pursuant to and in accordance with any Supply Agreement then in effect or, if no such Supply Agreement is then in effect, then Section 3.3.2 hereof shall remain in effect in relation to such Licensed Product(s) following such termination and Recepta shall be entitled to obtain supply of such Licensed Product(s) under any Supply Agreement entered into pursuant thereto after termination.

(c) During the Royalty Term for the Recepta Territory, Recepta’s Net Sales received pursuant to sales or transfers of Licensed Products by Recepta following termination will be subject to royalty payments as set forth in Sections 5.5 through Section 5.7 and subject to Section 5.8.2 all of which, for clarity, shall remain in effect. Thereafter, Recepta’s license under the Mersana Technology pursuant to Section 2.1.2 shall automatically become royalty-free and fully-paid upon the expiration of the Royalty Term in the Recepta Territory.

10.4 Availability of Cell Lines. In the event of any termination of this Agreement in its entirety by Mersana pursuant to Section 10.2.1 or by Recepta pursuant to Sections 10.2.2, 10.2.3 or 10.2.4(a), within [**] Business Days after Recepta’s written request, Mersana will make available to Recepta and extend to Recepta all necessary rights to use, without charge, any new cell lines owned or Controlled by Mersana as of the effective date of termination which are necessary or useful for the development and/or manufacture of the Antibody, subject to any restrictions or limitations set forth in any Third Party agreements governing the transfer or use or such cell lines. Such assistance may include, but will not be limited to, executing such agreements as may be necessary to release Xxxxxxx’s rights to such cell lines under Mersana’s agreements with its Third Party manufacturers. For the avoidance of doubt, Recepta shall be responsible for any reasonable and documented costs incurred by Mersana in connection with the storage and/or maintenance of the cell line(s) until such time as Recepta assumes responsibility for such storage and/or maintenance.

10.5 Accrued Rights; Surviving Obligations. Except as provided elsewhere, termination or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such termination or expiration. Such termination or expiration shall not relieve any Party from obligations which are expressly or by implication intended to survive termination or expiration of this Agreement, including, but not limited to, Articles 1 and 6 (but only for the [**] specified in Section 6.6), and Sections 2.4, 2.5, 4.4, 4.5, 5.9, 5.10, 5.11, 7.4, 8.1-8.3, 9.3, 9.4 (but only for so long as the license granted to Mersana under Section 2.1.1 remains in effect), 9.5, 10.3, 10.4, 11.1, 11.2, 11.4, 11.5, 11.7-11.19 and this Section 10.5. Termination or expiration of this Agreement shall not affect or prejudice any right of either Party to receive payments due hereunder or for which the event giving rise to such payment obligation has occurred prior the effectiveness of such termination or expiration (which, in the case of the payment contemplated by Section 5.1 is the execution and delivery of this Agreement by both Parties) and shall not preclude or hinder the terminating Party from also bringing, amending or pursuing an action against the other Party for damages and all other available legal and equitable remedies, subject to Section 11.7. In addition, Mersana’s obligations pursuant to Sections 5.2, 5.3, 5.4, 5.6 and 5.7 shall, subject to Section 5.8.1, survive and continue in accordance with their terms following any termination or expiration of this Agreement in respect of Mersana’s or any of its Affiliates’ or licensees’ continued Development or Commercialization of any Licensed Product, the Development, manufacture, use or Commercialization of which by Mersana or any of its Affiliates or sublicensees prior to the effective time of termination or expiration of this Agreement utilized any Recepta Know-How.

11. MISCELLANEOUS.

11.1 Publications. As between the Parties, and except for any required filings with any Regulatory Authority pursuant to a Party’s obligations hereunder to obtain Regulatory Approval in any jurisdiction, Xxxxxxx shall have the sole and exclusive right, but not the obligation, to make any publication in respect of the results arising out of Development of Licensed Products and Recepta shall make no such publication without the prior written consent of Mersana. Without limiting the preceding sentence, if Recepta wishes to make such a publication, then it will submit the proposed publication to Mersana at least [**] calendar days prior to the intended date of publication so that Mersana may, within [**] calendar days after its receipt of such proposed publication, identify to Recepta any of Xxxxxxx’s Confidential Information contained in the proposed publication. Recepta shall withhold publication of any of information timely identified to Recepta as Xxxxxxx’s Confidential Information for a period of up to [**] calendar days to allow for the filing of patent applications or the taking of such measures as may be appropriate to preserve proprietary rights in and the confidentiality of the information in the material being submitted for publication or presentation (including withholding such publication). By agreement of the Parties, this period may be further extended. The Parties will each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other parties in any such publications or presentations.

11.2 Public Announcements. Except as may be expressly permitted under this Section 11.2 or mandated by Applicable Laws or the rules of any stock exchange, neither Party will make any public announcement of any information regarding this Agreement without the prior written consent of the other Party, such consent not to be unreasonably withheld, conditioned or delayed. Once any statement is approved for disclosure by the Parties, either Party may make a subsequent public disclosure containing the same information disclosed in such prior public announcement without further approval of the other Party. Notwithstanding the above, the Parties shall issue the joint press release attached hereto as Exhibit 2 on the Effective Date.

11.3 No Debarred Personnel. Each Party agrees that it and its sublicensees shall not use, during the Term of this Agreement, the services of any employee, consultant, contractor or clinical investigator that has been debarred by the FDA or any other Governmental Authority or that is the subject of debarment proceedings by the FDA or any other Governmental Authority. If a Party becomes aware that it or its sublicensees has breached the foregoing obligation, it will immediately notify the other Party in writing and provide full details of the circumstances and extent of such breach.

11.4 Relationship of the Parties. Each Party shall bear its own costs incurred in the performance of its obligations hereunder without charge or expense to the other except as expressly provided in this Agreement. Neither Party shall have any responsibility for the hiring, termination or compensation of the other Party’s employees or for any employee benefits of such employee. No employee or representative of a Party shall have any authority to bind or obligate the other Party to this Agreement in any manner whatsoever, or to create or impose any contractual or other liability on the other Party without said Party’s approval. For all purposes, the Parties’ legal relationship under this Agreement to each other shall be that of independent contractor. This Agreement is not a partnership agreement and nothing in this Agreement shall be construed to establish a relationship of partners or joint venturers between the Parties.

11.5 Registration of this Agreement. To the extent, if any, that either Party concludes in good faith that it or the other Party is required to file or register this Agreement or a notification thereof with any Governmental Authority, such Party shall inform the other Party thereof. If both Parties jointly agree that either Party is required to submit or obtain any such

filing, registration or notification, they shall cooperate (Xxxxxxx’s cost and expense) in such filing, registration or notification and shall execute all documents reasonably required in connection therewith. In such filing, registration or notification, the Parties shall request confidential treatment of sensitive provisions of this Agreement, to the extent permitted by Applicable Law. The Parties shall promptly inform each other as to the activities or inquiries of any such Governmental Authority relating to this Agreement, and shall reasonably cooperate to respond to any request for further information therefrom on a timely basis. Mersana shall be responsible for all costs and expenses associated with any such filings or requirements.

11.6 Force Majeure. The occurrence of an event which materially interferes with the ability of a Party to perform its obligations or duties hereunder which is not within the reasonable control of the Party affected or any of its sublicensees, and which could not with the exercise of Diligent Efforts have been avoided (“Force Majeure Event”), including, but not limited to, war, rebellion, earthquake, fire, accident, strike, riot, civil commotion, act of God, inability to obtain raw materials, delay or errors by shipping companies or change in Applicable Law, shall not excuse such Party from the performance of its obligations or duties under this Agreement, but shall merely suspend such performance during the Force Majeure Event. The Party subject to a Force Majeure Event shall promptly notify the other Party of the occurrence and particulars of such Force Majeure Event and shall provide the other Party, from time to time, with its best estimate of the duration of such Force Majeure Event and with notice of the termination thereof. The Party so affected shall use Diligent Efforts to avoid or remove such causes of non-performance as soon as is reasonably practicable. Upon termination of the Force Majeure Event, the performance of any suspended obligation or duty shall without delay recommence. The Party subject to the Force Majeure Event shall not be liable to the other Party for any damages arising out of or relating to the suspension or termination of any of its obligations or duties under this Agreement by reason of the occurrence of a Force Majeure Event, provided such Party complies in all material respects with its obligations under this Section 11.6.

11.7 Dispute Resolution. In the event of any dispute, controversy or claim hereunder arising out of or relating to this Agreement, either Party may, on [**] Business Days written notice to the other Party, initiate binding arbitration in accordance with the then-current rules of the ICC governing the arbitration of commercial disputes. The Parties shall select a mutually acceptable arbitrator within [**] Business Days after the request of the Party invoking this dispute resolution procedure. If the Parties are unable to agree upon an arbitrator, the ICC shall select a qualified, independent arbitrator. Such arbitration will be held in New York, New York. The decision of the arbitrator will be final and binding on the Parties. The prevailing Party may enforce any arbitration decision or award exclusively in the federal and state courts in the State of New York, New York, USA. Notwithstanding the foregoing, either Party may seek injunctive, equitable or similar relief (without the requirement of arbitration) exclusively in any federal and state courts in the State of New York, New York, USA.

11.8 Governing Law. This Agreement shall be construed, and the respective rights of the Parties determined, according to the substantive law of New York without regard to the provisions governing conflict of laws, except matters of intellectual property law, which shall be determined in accordance with the intellectual property laws relevant to the intellectual property in question. The United Nations Convention on the International Sale of Goods shall not apply to this Agreement.

11.9 Attorneys’ Fees and Related Costs. In the event that any legal proceeding is brought to enforce or interpret any of the provisions of this Agreement, the prevailing Party shall be entitled to recover its reasonable attorneys’ fees, court costs and expenses of litigation whether or not the action or proceeding results in a final judgment.

11.10 Assignment. This Agreement may not be assigned or transferred by either Party, in whole or in part, whether voluntarily or by operation of law, without the prior written consent of the other Party; provided that either Party may assign this Agreement, in whole or in part, to any of its Affiliates if such Party guarantees the performance of this Agreement by such Affiliate; and provided further that either Party may assign this Agreement to a successor to all or substantially all of the business or assets of such Party to which this Agreement relates, whether by merger, sale of stock, sale of assets or other similar transaction. Any assignment in violation of this provision is void and without effect. This Agreement shall be binding upon and inure to the benefit of the Parties hereto, their permitted successors, legal representatives and assigns. In the event that Recepta assigns or transfers any of the Recepta Technology to a Third Party, Recepta shall impose on such assignee or transferee such obligations as are necessary so that Mersana retains and obtains all of the rights to which it is entitled with respect to such Recepta Technology under this Agreement.
