Sanofi shall promptly (and in any event within [***] days after the date of the complete Lead Identification Data Package) evaluate the Lead Identification Data Package to determine whether or not the applicable Small Molecule has achieved [***] and provide prompt written notice of such determination to EXS and, if [***] has been achieved, whether Sanofi wishes to either (i) continue with the Research Program with respect to that Approved Collaboration Target, in which case, to the extent a Research Milestone is payable in accordance with Clause 14.1, Sanofi shall pay the applicable Research Milestone Payment in accordance with this Agreement; or (ii) terminate the Research Program in accordance with the terms of this Agreement.

5.8With respect to each Approved Collaboration Target that is the subject of a Research Plan, EXS shall (a) promptly provide (and in any event within [***] days following the conclusion of the Research Plan) a written report to Sanofi when EXS believes that a Small Molecule for such Approved Collaboration Target has achieved [***] and (b) provide to Sanofi (i) the corresponding Development Candidate Data Package and (ii) such additional information that Sanofi may reasonably request and reasonable quantities of any assays, reagents, research tools and such Small Molecules for such Approved Collaboration Target that are reasonably necessary for Sanofi to determine whether such Small Molecule for such Approved Collaboration Target have achieved [***]. Except as otherwise set forth in a corresponding Research Plan, EXS shall deliver a Development Candidate Data Package for the Lead Molecule for an Approved Collaboration Target first and shall deliver a Development Candidate Data Package with respect to [***] Back-Up Molecules [***] for such Approved Collaboration Target by no later than [***] months following the delivery of the Development Candidate Data Package for the Lead Molecule. Sanofi shall promptly (and, in any event, within [***] days after the date of EXS’s delivery of each complete Development Candidate Data Package) evaluate such Development Candidate Data Package to determine whether or not the applicable Small Molecule has achieved [***] and provide prompt written notice of such determination to EXS.

5.9Notwithstanding anything to the contrary in Clause 5.8 (but without limiting EXS’s obligations to deliver Development Candidate Data Packages with respect to any Back-Up Molecules as required in Clause 5.8), if Sanofi provides notice to EXS that, with respect to a given Small Molecule for an Approved Collaboration Target, Sanofi desires to obtain delivery of the corresponding Development Candidate Data Package prior to its anticipated date of delivery because Sanofi believes that [***] with respect to that Small Molecule are likely to


			32

be met and desires to progress such Small Molecule into Development at an earlier date, then the Parties shall, acting reasonably and in good faith, discuss appropriate amendments to [***]; provided that the Parties intend to not discuss or make any such amendments during the [***] month period immediately preceding the anticipated date for delivery of such Development Candidate Data Package. If the Parties so agree to amend [***] and the applicable Small Molecule achieves the amended [***], then (a) EXS shall promptly deliver the corresponding Development Candidate Data Package to Sanofi within [***] days following the date that [***] amended and (b) such Small Molecule will be deemed to have been designated as a Collaboration Development Candidate that meets [***] for purposes of Clauses 6.1 and [***] as of the date of EXS’s delivery of the corresponding Development Candidate Data Package. [***] shall not withhold its agreement to any proposed amendment to [***] for the sole purpose of delaying the timing [***].

5.10By no later than [***] Business Days following Sanofi’s receipt of a Lead Identification Data Package or Development Candidate Data Package for an Approved Collaboration Target, Sanofi may (a) notify EXS in writing that such Lead Identification Data Package or Development Candidate Data Package is incomplete or inconsistent, in which case EXS shall use Commercially Reasonable Efforts to address Sanofi’s concerns and deliver to Sanofi a complete Lead Identification Data Package or Development Candidate Data Package as promptly as practicable or (b) provide EXS with written notice requesting a discussion with EXS representative(s) who have the relevant knowledge and information regarding such Approved Collaboration Target or the Small Molecules relating to such Approved Collaboration Target, in which case EXS shall require such representatives to meet with Sanofi to discuss as soon as reasonably practicable.

5.11Each Party shall prepare and maintain complete and accurate written records of all activities performed as well as results and data obtained pursuant to each Research Plan or NSM Research Plan, in sufficient detail and in good scientific manner appropriate for patent and regulatory purposes. In addition to the reporting obligations set forth in Clause 5.12, upon reasonable request of Sanofi, EXS will grant Sanofi and its Affiliates reasonable access to all results and data (including all primary data and data contained in laboratory notebooks) that is generated in the course of performance of each Research Plan and NSM Research Plan in a format reasonably acceptable to both Parties (including interim results, chemical structures and drug design strategies arising out of the Research Plan or NSM Research Plan). EXS shall consider in good faith any reasonable comments arising out of Sanofi’s review of such results and data and provided by Sanofi in writing to EXS’s Alliance Manager and make reasonable adjustments to the applicable Research Plan or NSM Research Plan in order to account for those reasonable comments. Sanofi and its Affiliates will also have the right, at reasonable intervals and upon reasonable notice to EXS, to have copies of such records made to use and transfer as permitted hereunder. All such records in their disclosed form will be deemed the Confidential Information of each Party (without affecting the ownership of or confidentiality and non-use obligations related to the information therein).

5.12Each Party will furnish to the Joint Steering Committee, at each Joint Steering Committee meeting, to the extent applicable to such Party, an update on such Party’s progress under the Research Plan for an Approved Collaboration Target or the NSM Research Plan for any Collaboration NSM Target during the relevant Calendar Quarter, including a summary of any


			33

material results and data generated by such Party under such Research Plan or NSM Research Plan since the previous Joint Steering Committee meeting. Such Party shall provide the Joint Steering Committee with such other results, data and other information with respect to the activities under the Research Plan or NSM Research Plan as any member of the Joint Steering Committee may reasonably request that are in such Party’s possession or control and are reasonably necessary or useful for the Joint Steering Committee to perform its responsibilities under Clause 11 or for either Party to exercise its rights under this Agreement. Upon reasonable request by a Party, through the Joint Steering Committee, the other Party shall provide the Joint Steering Committee with such other information and such additional access to records with respect to any Approved Collaboration Target or Collaboration NSM Target that is the subject of a Research Plan or NSM Research Plan as the Joint Steering Committee or such other Party may reasonably request for the conduct or evaluation of the Research Program, including data that is specific to the applicable Research Program (e.g., underlying datasets that are specific to the applicable Research Program and which are used by a Party in the course of conducting its activities with respect to the applicable Research Program). Nothing in this Clause 5.12 will require a Party to provide any data to the other Party if doing so would be contrary to Applicable Laws.

5.13Sanofi will have the right to perform [***] activities under a Research Plan for each Approved Collaboration Target, including [***]. In the event of a dispute regarding the scope of the activities to be performed by Sanofi under that Research Plan, Sanofi will have final decision-making authority regarding that scope, and EXS shall not unreasonably withhold, delay or condition its approval of that scope. If Sanofi performs any such activities, then EXS shall transfer, upon Sanofi’s request and at no cost to Sanofi, adequate amounts of materials, which Sanofi may use in accordance with the terms and conditions of this Agreement (including the applicable Research Plan) and any Material Transfer Agreement entered into between the Parties). Prior to EXS transferring any such materials to Sanofi, the Parties shall enter into a Material Transfer Agreement in the form attached as Schedule 5.

5.14Sanofi may provide EXS with (a) Sanofi-Originated Molecules Directed To an Approved Collaboration Target or other materials, in each case developed outside of this Agreement and Controlled by Sanofi or its Affiliates (“Sanofi Materials”) or (b) Sanofi-Provided Data, which Sanofi may use in accordance with the terms and conditions of this Agreement (including the applicable Research Plan) and any Material Transfer Agreement entered into between the Parties. Prior to Sanofi transferring any Sanofi Materials to EXS, the Parties shall enter into a Material Transfer Agreement in the form attached as Schedule 5.

6.DEVELOPMENT

6.1As soon as practicable (and, in any event, within [***] days following the delivery of a complete Development Candidate Data Package for that Approved Collaboration Target), Sanofi shall notify EXS of whether Sanofi elects to designate the Small Molecule that is the subject of such Development Candidate Data Package as a Collaboration Development Candidate to be progressed to Development. Sanofi will have the right, in its sole discretion, to designate any Small Molecule(s) arising out of a Research Plan as a Collaboration Development Candidate, irrespective of whether such Small Molecule meets [***]. If, at any time, Sanofi elects to advance into Development any Small Molecule which has not met [***]


			34

(including [***] may be amended in accordance with Clause 5.8), then (a) such Small Molecule will be deemed designated as an “Advanced-At-Risk Candidate” and [***], and the [***] with respect to such Small Molecule will be adjusted as set out in Clause [***]; and (b) during the period following Sanofi’s election to advance an Advanced-At-Risk Candidate through the start of the first Phase 1 Clinical Trial intended to be relied upon for an application for a Regulatory Approval in a Major Country for that Advanced-At-Risk Candidate, such At-Risk-Candidate will not be deemed a Collaboration Development Candidate for the purposes of Clauses [***] (but, for the avoidance of doubt, such At-Risk-Candidate is a Collaboration Development Candidate for all other purposes under this Agreement). Without limiting Sanofi’s rights under Clauses 4.4 or 32.4, if Sanofi does not designate any Collaboration Development Candidate for an Approved Collaboration Target within [***] days following the delivery of the final complete Development Candidate Data Package (other than if agreed by EXS), then this Agreement with respect to that Approved Collaboration Target will be deemed to have been terminated by Sanofi under Clause 32.2 and such Approved Collaboration Target will be deemed a Terminated Target.

6.2With respect to a given Approved Collaboration Target, EXS shall promptly (but no later than [***] days) following each selection of a Collaboration Development Candidate for such Approved Collaboration Target pursuant to Clause 6.1 and at the end of the Research Program (for each Approved Collaboration Target, the “Handoff”), transfer to Sanofi or its designated Affiliate a copy of all Know-How (i) related to the Collaboration Development Candidates for such Approved Collaboration Target in its possession or Control as of the Handoff or (ii) otherwise included in the EXS Project IP, Sanofi Collaboration IP [***], including any documentation (whether held in paper or electronic format) or similar removable media (including emails, documents, spreadsheets, copies of standard operating procedures or technical specifications) in a format agreed by the Parties. For a given Approved Collaboration Target, after the Handoff for such Approved Collaboration Target, if Sanofi reasonably believes that EXS has not delivered all Know-How that it is required to deliver pursuant to this Clause 6.2, Sanofi may request any missing Know-How from EXS. EXS shall use Commercially Reasonable Efforts to address Sanofi’s request and, where applicable, deliver to Sanofi a copy of the missing Know-How as promptly as practicable.

6.3To assist with the transfer of Know-How under this Clause 6, for [***] months after the date of Handoff with respect to a given Approved Collaboration Target (if any), EXS shall answer any reasonable queries from Sanofi during normal business hours to transfer such Know-How for such Approved Collaboration Target to Sanofi and to respond to Sanofi’s reasonable inquiries with respect thereto. All assistance provided pursuant to this Clause 6.3 will be at [***] cost and expense.

6.4After the Handoff for a given Approved Collaboration Target, if Sanofi reasonably believes that any materials that were developed or used by or on or on behalf of EXS or its Affiliates in the Small Molecule Research Project are reasonably necessary for the Development or Manufacturing of the Collaboration Development Candidates or Qualifying Small Molecule Products by or on behalf of Sanofi, then Sanofi may request in writing that EXS transfer to Sanofi a reasonable quantity of such materials to enable Sanofi to perform its Development or Manufacturing activities under this Agreement. EXS shall not unreasonably withhold its consent to any such request.

30CONFIDENTIALITY

30.1The Receiving Party which receives the Confidential Information of the Disclosing Party pursuant to or in connection with this Agreement will: (a) maintain in confidence such Confidential Information using not less than the efforts that such Receiving Party uses to maintain in confidence its own proprietary information of similar kind and value, but in no event less than a reasonable degree of efforts; (b) not disclose such Confidential Information to any Third Party without first obtaining the prior written consent of the Disclosing Party, except for disclosures expressly permitted pursuant to this Clause 30; and (c) not use such Confidential Information for any purpose except those expressly permitted under this Agreement, which permitted uses include, in the case of Sanofi, the exercise of the rights, licences and options granted to Sanofi hereunder. The obligations of confidentiality, non-disclosure and non-use under this Clause 30.1 will be in full force and effect from the Effective Date until [***] years following the expiration or termination of this Agreement.

30.2Notwithstanding Clause 30.1, the Receiving Party may disclose Confidential Information belonging to the Disclosing Party:

(a)as permitted by and in accordance with Clause 30.4, to the U.S. Securities and Exchange Commission or any national securities exchange in any jurisdiction in the Territory (each, a “Securities Regulator”);

(b)in response to a valid order of a court of competent jurisdiction or other Governmental Authority or, if in the reasonable opinion of the Receiving Party’s legal counsel, such disclosure is otherwise required by Applicable Law (other than to a Securities Regulator); provided that to the extent legally permissible the Receiving Party will first give written notice to the Disclosing Party and give the Disclosing


			61

Party a reasonable opportunity to (i) quash any such order; (ii) obtain a protective order or confidential treatment requiring that the Confidential Information that is the subject of such order or Applicable Law (A) be held in confidence by the recipient and (B) be used only for the purposes for which the order was issued or as required by Applicable Law; or (iii) propose redactions to such Confidential Information; and provided, further, that any Confidential Information disclosed in response to any such order or Applicable Law will be limited to that information which is legally required to be disclosed in response thereto;

(c)by the Receiving Party, to the extent reasonably necessary to exercise its rights or perform its obligations to Prosecute and Maintain any Patent Rights for which it has a Prosecution and Maintenance right or obligation under Clause 23;

(d)by Sanofi, as the Receiving Party, to a Regulatory Authority, as reasonably required in connection with any filing, submission or communication with respect to any Qualifying Molecule or Qualifying Product, provided that Sanofi gives EXS a reasonable opportunity to obtain a protective order or confidential treatment requiring that the relevant Confidential Information be held in confidence by the recipient and be used only for the purposes required and to propose redactions to the relevant Confidential Information;

(e)by EXS, as the Receiving Party, to a Regulatory Authority, as reasonably required in connection with any filing, submission or communication with respect to any Termination Molecule or Termination Product, provided that EXS gives Sanofi a reasonable opportunity to obtain a protective order or confidential treatment requiring that the relevant Confidential Information be held in confidence by the recipient and be used only for the purposes required and to propose redactions to the relevant Confidential Information;

(f)(i) to any of the Receiving Party’s officers, employees, consultants, agents or Affiliates who need to know such Confidential Information to perform on behalf of such Receiving Party under this Agreement or (ii) in the case of Sanofi, as the Receiving Party, to any actual or potential collaborators, partners, licensees, Sublicensees or subcontractors in connection with the Research, Development, Manufacture or Commercialisation of Qualifying Molecules or Qualifying Products or otherwise to the extent necessary or useful for Sanofi to exercise its rights or perform its obligations hereunder; provided that, in each case ((i) and (ii)), prior to any such disclosure, each disclosee will be bound by written obligations of confidentiality, non-disclosure and non-use no less restrictive than the obligations set forth in this Clause 30; and provided, further, that the Receiving Party will remain responsible for any failure by any such disclosee to treat such Confidential Information as required under this Clause 30; and

(g)to its advisers (including attorneys and accountants) in connection with activities under this Agreement; provided that prior to any such disclosure, each such disclosee will be bound by written obligations of confidentiality, non-disclosure and non-use no less restrictive than the obligations set forth in this Clause 30 (provided, however, that


			62

in the case of legal advisers, no written agreement will be required); and provided, further, that the Receiving Party will remain responsible for any failure by any such disclosee to treat such Confidential Information as required under this Clause 30.

If and whenever any Confidential Information is disclosed in accordance with this Clause 30.2, such disclosure will not cause any such information to cease to be Confidential Information, except to the extent that such disclosure results in a public disclosure of such information other than by breach of this Agreement.

30.3Clause 30.1 will not apply to any portion of the Confidential Information of the Disclosing Party to the extent such Confidential Information:

(a)was known to the Receiving Party or any of its Affiliates, as evidenced by written records, without any obligation to the Disclosing Party to keep it confidential or to restrict its use, prior to disclosure by the Disclosing Party;

(b)is subsequently disclosed to the Receiving Party or any of its Affiliates by a Third Party lawfully in possession thereof and without any obligation to the Disclosing Party to keep it confidential or to restrict its use;

(c)is published by a Third Party or otherwise becomes publicly available or enters the public domain, either before or after it is disclosed to the Receiving Party, without any breach by the Receiving Party of its obligations hereunder; or

(d)is independently developed by or for the Receiving Party or any of its Affiliates, as evidenced by written records, without reference to or reliance upon the Disclosing Party’s Confidential Information.

Any combination of features or disclosures will not be deemed to fall within the foregoing exclusions merely because individual features are published or available to the general public or in the rightful possession of the Receiving Party unless the combination itself and principles of operation are published or available to the general public or in the rightful possession of the Receiving Party.

30.4Each Party acknowledges and agrees that the other Party may submit this Agreement to, or file this Agreement with, the Securities Regulators or to other Persons as may be required by Applicable Law, and if a Party submits this Agreement to, or files this Agreement with, any Securities Regulator or other Person as may be required by Applicable Law, such Party agrees to consult with the other Party with respect to the preparation and submission of a confidential treatment request for this Agreement. Notwithstanding the foregoing, if a Party is required by any Securities Regulator or other Person as may be required by Applicable Law to make a disclosure of the terms of this Agreement in a filing or other submission as required by such Securities Regulator or such other Person, and such Party has: (a) provided copies of the disclosure to the other Party reasonably in advance under the circumstances of such filing or other disclosure; (b) promptly notified the other Party in writing of such requirement and any respective timing constraints; and (c) given the other Party reasonable time under the circumstances from the date of provision of copies of such disclosure to comment upon and request confidential treatment for such disclosure, then such Party will have the right to make


			63

such disclosure at the time and in the manner reasonably determined by its counsel to be required by the Securities Regulator or the other Person. Notwithstanding the foregoing, if a Party seeks to make a disclosure as required by a Securities Regulator or other Person as may be required by Applicable Law as set forth in this Clause 30.4 and the other Party provides comments in accordance with this Clause 30.4, the Party seeking to make such disclosure or its counsel, as the case may be, will incorporate such comments to the extent legally permissible.

30.5During the Research Term, neither Party shall publicly present, publish or otherwise publicly disclose any paper, publication, oral presentation, abstract, poster, manuscript or other presentation relating to any activity or other matter under this Agreement (each, a “Publication”), without the other Party’s prior written consent. Following the Research Term, Sanofi will be responsible for and control all Publications relating to the (a) Approved Collaboration Targets, (b) Non-Small Molecule Targets that are, or, at any time during the Research Term, were, the subject of any activity under a NSM Research Plan, (c) Qualifying Molecules and (d) Qualifying Products and, in each case ((a) through (d)), EXS shall not make any such Publication without the prior written consent of Sanofi. EXS will be responsible for and control all Publications relating to the Termination Molecules and Termination Products and Sanofi shall not make any such Publication without the prior written consent of EXS. To the extent a Party has a right pursuant to this Clause 30.5 to make a Publication, then the publishing Party (the “Publishing Party”) shall provide to the other Party (the “Reviewing Party”) an opportunity to review such Publication to determine whether such Publication contains the Confidential Information of the Reviewing Party. The Publishing Party will deliver to the Reviewing Party a copy of any such proposed Publication or an outline of the proposed oral disclosure, together with any slides or other materials to be provided in connection with such oral disclosure, at least [***] days prior to submission for publication or presentation for review by the Reviewing Party. The Reviewing Party will have the right, in its sole discretion, to: (i) require the removal of its Confidential Information from any such Publication by the Publishing Party or (ii) request a reasonable delay in publication or presentation in order to protect its patentable information. If the Reviewing Party requests such a delay, then the Publishing Party shall delay submission or presentation for a period of [***] days after its provision of the copy of the proposed publication or disclosure to enable the filings of patent applications protecting the Reviewing Party’s rights in such information.

30.6Nothing contained in Clause 30.5 prohibits the inclusion of information in a patent application claiming, and in furtherance of, the manufacture, use, sale or formulation of an Approved Collaboration Target or Qualifying Product, provided that such application is made in accordance with Clause 30.5.

30.7Notwithstanding anything to the contrary in this Agreement, Sanofi and its Affiliates and Sublicensees, and its or their designees, will have the right to publish registry information and summaries of data and results from any Clinical Trials conducted in connection with Qualifying Molecules or Qualifying Products and EXS and its Affiliates and permitted subcontractors and sublicensees, and its or their designees, will have the right to publish registry information and summaries of data and results from any Clinical Trials conducted in connection with Termination Molecules or Termination Products, on its or their Clinical


			64

Trials registry or on a government-sponsored database (such as xxx.xxxxxxxxxxxxxx.xxx), without first obtaining the prior consent of the other Party. The Parties will reasonably cooperate if required or reasonably requested by a Party in order to facilitate any such publication.

31.PRESS RELEASES

Each Party will have the right to issue an individual press release announcing the execution of this Agreement in a form to be agreed between the Parties in writing upon a mutually agreed-upon date after the Effective Date, but within [***] days thereafter. Neither Party will make any other press release or other public statement disclosing this Agreement or the activities hereunder or transactions contemplated hereby, without the other Party’s prior written consent, provided that:

(a)the contents of any press release or other public statement that has been reviewed and approved by a Party may be re-released by the other Party in exactly the same language as previously approved without first obtaining the other Party’s prior written consent in accordance with this Clause 31; and

(b)Sanofi may make a press release or public statement concerning a Qualifying Product that does not contain any Confidential Information of EXS or reference EXS or its Affiliates or this Agreement.

32.TERM AND TERMINATION

32.1This Agreement will become effective on the Effective Date and, on an Approved Collaboration Target-by-Approved Collaboration Target or Collaboration NSM Target-by-Collaboration NSM Target basis, unless earlier terminated pursuant to this Clause 32, will continue through the applicable Term for each Approved Collaboration Target or Collaboration NSM Target.

32.2Sanofi may terminate this Agreement as a whole, or on an Approved Collaboration Target-by-Collaboration Target or Collaboration NSM Target-by-Collaboration NSM Target basis, at any time after the Effective Date, for any reason or no reason, effective upon not less than [***] days’ written notice to EXS.

32.3Sanofi may terminate this Agreement on an Approved Collaboration Target-by-Collaboration Target or Collaboration NSM Target-by-Collaboration NSM Target basis upon written notice to EXS based on Safety Reasons. Upon such termination for Safety Reasons, Sanofi will be responsible, at its cost and expense, for the wind down of any Development of applicable Qualifying Products for such Approved Collaboration Target or Collaboration NSM Target (including any Clinical Trials for the applicable Qualifying Product being conducted by or on behalf of Sanofi) and any Commercialisation activities for applicable Qualifying Products for such Approved Collaboration Target or Collaboration NSM Target. Such termination will become effective upon the date that Sanofi notifies EXS in writing that such wind-down is complete.


			65

32.4If a Party materially breaches this Agreement with respect to one or more Approved Collaboration Targets or Collaboration NSM Targets, then the other Party may terminate this Agreement with respect to the affected Approved Collaboration Target or Collaboration NSM Target if such breach has continued for (a) [***] days in the case of a material breach as a result of non-payment, or (b) [***] days in the case of any other material breach, after written notice has been provided to the breaching Party by the non-breaching Party requiring such breach to be remedied and stating an intention to terminate if not so cured (such period, the “Cure Period”) and such notice, a “Termination Notice”). Except as set forth in this Clause 32.4, any such termination will become effective at the end of such Cure Period unless the breaching Party has cured any such breach prior to the expiration of the Cure Period or, if a material breach described in sub-clause (b) above is a breach of a Party’s obligations to use Commercially Reasonable Efforts for Research, Development or Commercialisation under this Agreement, the alleged breaching Party has re-commenced use of those Commercially Reasonable Efforts during such Cure Period.

32.5A Party will have the right to terminate this Agreement upon written notice if the other Party incurs an Insolvency Event; provided, however, in the case of any involuntary bankruptcy proceeding, such right to terminate will only become effective if the Party that incurs the Insolvency Event consents to the involuntary bankruptcy or if such proceeding is not dismissed or stayed within [***] days after the filing thereof. For purposes of Section 365(n) of the Code and any similar law, foreign or domestic, all rights and licences granted under or pursuant to any Clause of this Agreement are rights to “intellectual property” (as defined in Section 101(35A) of the Code). The Parties agree that the licensee of such rights under this Agreement will retain and may fully exercise all of its protections, rights and elections under the Code and any similar laws in any other country. Each Party hereby acknowledges that copies of research data, laboratory samples, product samples and inventory, formulas, laboratory notes and notebooks, pre-clinical research data and results, tangible Know-How and rights of reference, in each case that relate to such intellectual property, constitute “embodiments” of such intellectual property pursuant to Section 365(n) of the Code, and that the licensee will be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, and the same, if not already in its possession, will be promptly delivered to it upon its written request therefor and election under Section 365(n)(1)(B) of the Code to retain the licences granted hereunder. The provisions of this Clause 32.5 are without prejudice to any rights the non-subject Party may have arising under the Code, laws of other jurisdictions governing insolvency and bankruptcy or other Applicable Law. The Parties agree that they intend the following rights to extend to the maximum extent permitted by law, including for purposes of the Code and any similar laws in any other country: (x) the right of access to any intellectual property (including all embodiments thereof) of the licensor, or any Third Party with whom the licensor contracts to perform an obligation of such licensor under this Agreement which is necessary for the Development, Manufacture or Commercialisation of a Qualifying Product; (y) the right to contract directly with any Third Party described in (x) to complete the contracted work and (z) the right to cure any breach of or default under any such agreement with a Third Party and set off the costs thereof against amounts payable to such licensor under this Agreement.


			66

32.6With respect to any Approved Collaboration Target or Collaboration NSM Target for which this Agreement has been terminated: (a) such Target will no longer be considered an Approved Collaboration Target or Collaboration NSM Target for all purposes of this Agreement and will become a Terminated Target and (b) except to the extent expressly set forth herein, each Party’s rights and obligations under this Agreement with respect to the Research, Development, Manufacture, Commercialisation or other exploitation of such Terminated Target(s) shall automatically cease as of the effective date of termination. For clarity, if this Agreement is terminated in its entirety, then all Approved Collaboration Targets and Collaboration NSM Targets will be Terminated Targets.

33.EFFECT OF TERMINATION; REVERSION

33.1Upon termination of this Agreement in its entirety or with respect to one (1) or more Approved Collaboration Target(s) or Collaboration NSM Target(s) by a Party pursuant to Clauses 32.2 through 32.6, the following terms will apply to this Agreement, either in its entirety or with respect to Collaboration Target(s) or Collaboration NSM Target(s) that are the subject of such termination, as the case may be, and except as the application of such Clauses may be limited as provided in a given sub-clause of this Clause 33.1:

(a)except in the case of EXS for any Confidential Information of Sanofi that is Reversion IP and in the case of Sanofi for any Confidential Information of EXS that Sanofi is entitled to use in order to exercise any of its rights or perform any of its obligations under this Agreement that survive expiration or termination, within [***] days after the effective date of termination with respect to an Approved Collaboration Target(s) or Collaboration NSM Target(s), each Party shall destroy all tangible items comprising, bearing or containing any Confidential Information of the other Party that are in its or its Affiliates’ Control that is solely related to such terminated Approved Collaboration Target or Collaboration NSM Target; provided, that such Party may retain one copy of such Confidential Information for its legal archives, and provided further that such Party shall not be required to destroy electronic files containing Confidential Information that are made in the ordinary course of its business information back-up procedures pursuant to its electronic record retention and destruction practices that apply to its own general electronic files and information;

(b)EXS will remain entitled to receive all payments that accrued but were unpaid before the effective date of such termination;

(c)if this Agreement is terminated in its entirety, then the Joint Steering Committee (and all Subcommittees) will be dissolved as of the effective date of such termination; and

(d)certain provisions herein will survive termination, in accordance with Clause 33.5.

33.2Upon termination of this Agreement by Sanofi under Clause 32.2 or by EXS under Clause 32.4 or Clause 32.5, solely with respect to the applicable terminated Approved Collaboration Targets(s) (and not, for clarity, with respect to terminated NSM Collaboration Targets), the following will apply with respect to (x) the Licensed Development Candidates (“Termination Molecules”) for such Terminated Target(s) and (y) any product in the Field that (A) is Directed To such Terminated Target; and (B) contains or comprises a Termination


			67

Molecule (each, a “Termination Product”) for such Terminated Target(s) (in addition to any other rights, obligations or remedies under this Agreement with respect to such termination):

(a)the scope of the licence granted to Sanofi under Clause 20.1(a) will be amended such that it is for all purposes except for the Research, Development, Manufacture or Commercialisation of the Termination Molecules and Termination Products for the applicable Terminated Target(s);

(c)Sanofi shall, on request of EXS, promptly return to EXS or destroy all Confidential Information of EXS that relates exclusively to the Terminated Target(s), save to the extent Sanofi is required to retain a copy for compliance with Applicable Law; and

(d)Sanofi shall grant, and hereby grants, to EXS for any Termination Product that [***] (each, a “Reversion Molecule” and a “Reversion Product”, respectively) [***], perpetual, irrevocable, freely transferable, worldwide licence, with the right to grant sublicences through multiple tiers, to Research, Develop, Manufacture, and Commercialise such Reversion Molecules and Reversion Products: (A) [***] (for the purposes set forth below), sublicensable (through multiple tiers of sublicensees) licence for purposes of Research, Development, Manufacture and Commercialisation of such Reversion Molecules or Reversion Products, and (B) [***], sublicensable (through multiple tiers of sublicensees) licence for purposes of Research, Development, Manufacture, and Commercialisation of such Reversion Molecules or Reversion Products, under all of Sanofi’s or its Affiliates’ right, title and interest in and to, [***] (collectively, the “Reversion IP”), provided that, in consideration for such licence, on a Reversion Product-by-Reversion Product basis, the Parties shall negotiate in good faith, and EXS shall pay Sanofi, a reasonable royalty on net sales of all Reversion Products, on a Reversion Product-by-Reversion Product and country-by-country basis for a royalty term to be negotiated in good faith by the Parties, but consistent with the Royalty Term. If the Parties are unable to agree on the reasonable royalty rate or term under this Clause 33.2(d), either Party may submit such dispute to arbitration for resolution in accordance with the provisions in Clause 38.

33.3Upon the expiration of the Royalty Term (i.e. in the case where there is no earlier termination pursuant to Clause 32), on a Licensed Collaboration Development Candidate-by-Licensed Collaboration Development Candidate basis and Licensed Small Molecule Product-by-Licensed Small Molecule Product and country-by-country basis, the licences granted to Sanofi under Clause 20.1 with respect to EXS Project IP, EXS Background IP [***] will convert to a perpetual, fully paid-up, non-royalty-bearing licence. Certain provisions herein will survive expiration, in accordance with Clause 33.5.

33.4Except as otherwise provided in Clause 32 or 33, expiration or earlier termination of this Agreement for any reason shall not release either Party from any liability or obligation


			68

(including payments) that already has accrued prior to such expiration or termination, nor affect the survival of any provision hereof to the extent it is expressly stated to survive such termination. Subject to and without limiting the terms and conditions of this Agreement (including Clause 28), expiration or termination of this Agreement will not preclude any Party from (a) claiming any other damages, compensation or relief that it may be entitled to upon such expiration or termination, (b) subject to Clause 33.3, any right to receive any amounts accrued under this Agreement prior to the expiration or termination date but which are unpaid or become payable thereafter and (c) any right to obtain performance of any obligation provided for in this Agreement which shall survive expiration or termination.

33.5Termination or expiration of this Agreement in its entirety or with respect to an Approved Collaboration Target or Collaboration NSM Target will not affect rights or obligations of the Parties under this Agreement that have accrued prior to the date of termination or expiration of this Agreement in its entirety or with respect to such Target. Notwithstanding anything to the contrary, the following provisions will survive and apply after expiration or termination of this Agreement: Clauses 1, 2.1(a), 2.1(e), 20.1(a), 20.1(c), 20.3, 20.4, 20.5, 21.2, 21.4, 21.5, 21.6, 22, 28, 29, 30.1, 30.2, 30.3, 30.7, 33, 37, 38 and 39.

34FORCE MAJEURE

34.1Neither Party shall be liable to the other Party for any delay or non-performance of its obligations under this Agreement if such delay or non-performance arises directly from any Force Majeure Event, and the performance of the affected Party’s obligations, to the extent affected by the cause, shall be suspended during the period that the Force Majeure Event persists; provided that:

(a)the affected Party promptly notifies the other Party (but no later than [***] days after such occurrence) in writing of the cause and nature of the Force Majeure Event, the likely duration of the delay or non-performance and any action being taken by such affected Party to avoid or minimise the effect;

(b)the affected Party will use reasonable efforts to limit to avoid or remove such causes of delay or non-performance and to mitigate the effect of the Force Majeure Event on such Party, and will continue performance in accordance with the terms of this Agreement whenever such causes are removed; and

(c)the suspension of performance by the affected Party will be of no greater scope and no longer duration than is necessary under the circumstances.

34.2When such circumstances arise, the Parties will negotiate in good faith any modifications of the terms of this Agreement that may be necessary or appropriate in order to arrive at an equitable solution.

34.3The Parties agree the effects of the COVID-19 pandemic that is ongoing as of the Effective Date may be invoked by a Party as a Force Majeure Event for the purposes of this Agreement to the extent such effect was beyond the reasonable control of the affected Party and could not reasonably be planned for or avoided.


			69

35.RECORDS AND AUDIT

35.1Each Party shall (and shall procure that any subcontractors shall) maintain full and accurate records, and in good scientific manner, of:

(a)all work done and results achieved in the performance of its responsibilities under each Research Plan and NSM Research Plan;

(b)with respect to any Cost Share Candidate, the Clinical Development Costs incurred by that Party; and

(c)in respect of Sanofi, the information set out in Clause 18.5.

35.5If any audit reveals an underpayment, the audited Party shall pay the Auditing Party the amount of such underpayment within [***] days after becoming aware of the underpayment. If the underpayment exceeds [***] per cent [***] of the aggregate amount of payments that are subject to the audit, the audited Party shall pay for the Auditing Party’s reasonably incurred costs and expenses in respect of the audit.

36.ASSIGNMENT

36.1Subject to Clauses 5.5, 20.4 and 36.2, neither Party may assign or transfer this Agreement, whether by operation of law or otherwise, or any of its rights or obligations under this Agreement, without the prior written consent of the other Party.

36.2Nothing in this Agreement shall prevent or restrict a Party from assigning, without the other Party’s consent, this Agreement or such Party’s rights or obligations hereunder, in whole or in part, to: (a) any of its Affiliates; (b) its successor in interest in the transfer or sale of all or substantially all of its assets or business related to the subject matter of this Agreement (or the applicable Qualifying Molecule(s) or Qualifying Product(s)); or (c) its successor in interest in a merger or consolidation (or similar transaction) of the assigning Party, provided that, in each case, the assigning Party notifies the other Party within [***] calendar days after such assignment. In the event that a permitted assignment of this Agreement by a Party increases the tax liability of the other Party or any of its Affiliates over the amount of any Taxes that


			70

otherwise would have been payable in the absence of such assignment, the assigning Party will reimburse the other Party for the amount of such increased Tax liability.

37.GENERAL

37.1Status

Sanofi and EXS are independent contractors under this Agreement. Nothing in this Agreement is intended or shall be construed to constitute either Party as a partner, agent or joint venturer of the other Party.

(b)are cumulative and not exclusive of rights or remedies provided by law; and

(c)may be waived, and the obligations of each Party hereunder may be released, only in writing signed by the Parties and specifically.

If one (1) or more of the terms or provisions of this Agreement is held by a court of competent jurisdiction to be void, invalid or unenforceable in any situation in any jurisdiction, such holding will not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the void, invalid or unenforceable term or provision in any other situation or in any other jurisdiction, and the term or provision will be considered severed from this Agreement solely for purposes of such situation and solely in such jurisdiction. If the final judgment of a court of competent jurisdiction holds that any term or provision hereof is void, invalid or unenforceable, the Parties agree to: (a) reduce the scope, duration, area or applicability of the term or provision or to delete specific words or phrases to the minimum extent necessary to cause such term or provision as so reduced or amended to be enforceable; and (b) make a good faith effort to replace any void, invalid or unenforceable term or provision with a valid and enforceable term or provision such that the objectives contemplated by the Parties when entering this Agreement may be realised.

37.13Interpretation

This Agreement has been diligently reviewed by and negotiated by and between the Parties, and in such negotiations each of the Parties has been represented by competent (in-house or external) counsel, and the final agreement contained herein, including the language whereby it has been expressed, represents the joint efforts of the Parties and their counsel. Accordingly, in interpreting this Agreement or any provision hereof, no presumption will apply against any Party as being responsible for the wording or drafting of this Agreement or any such provision, and ambiguities, if any, in this Agreement will not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision.
