Notwithstanding the above obligations of confidentiality and non-use, a Party may disclose information to the extent that such disclosure is reasonably necessary in connection with:

(i) filing or prosecuting patent applications, subject to the terms of Section 7.2 or Section 7.3;

(ii) prosecuting or defending litigation as permitted herein;

8.2 Publications. Company shall have the right to publicly present or publish information relating to the Compounds or Products, including all Know-How generated by or on behalf of Company hereunder (including from any Clinical Studies conducted by Company) with respect to any Product (each such proposed presentation or publication, a “Company Publication”) in accordance with this Section 8.2. Company shall provide the MRKDG Alliance Manager with a copy of each proposed Company Publication at least [*] prior to the earlier of its presentation or intended submission for publication; provided that in the case of abstracts, this period shall be at least [*] (such applicable period, the “Review Period”).

If Company receives comments from MRKDG during the applicable Review Period, it shall consider the comments of MRKDG in good faith, but will retain the sole authority to submit the manuscript for such Company Publication, provided that Company agrees to (A) delete any Confidential Information of MRKDG that MRKDG identifies for deletion in its comments (except for information has already been publicly disclosed either prior to the Effective Date or after the Effective Date through no fault of Company or otherwise not in violation of this Agreement), and (B) delay such Company Publication for a period of up to an additional [*] after the end of the applicable Review Period to enable MRKDG to draft and file Patent Rights with respect to any subject matter to be made public in such Company Publication and to which MRKDG has the applicable intellectual property rights to file such Patent Rights. MRKDG and MRKDG’s licensees and contractors shall have the right to publish the results of the Existing Clinical Studies; provided, however, that MRKDG shall submit such publications to Company in advance and shall take into account, or use Commercially Reasonable Efforts to cause its licensee or contractor, as applicable, to take into account, comments made by Company. Subject to the foregoing, with respect to any MRKDG Know-How that is specific to a Compound or Product (to the extent such MRKDG Know-How has not been previously publicly presented or published either (i) prior to the Effective Date or (ii) after the Effective Date in compliance with this Agreement), except as required by Applicable Law, MRKDG shall not publicly present or publish such MRKDG Know-How unless such presentation or publication is approved by Company in writing, such approval not to be unreasonably withheld, conditioned or delayed.

ARTICLE 10 INDEMNIFICATION AND INSURANCE

10.1 Indemnification by MRKDG. MRKDG shall defend, indemnify, and hold harmless Company, its Affiliates, directors, employees, and agents (collectively, the “Licensee Indemnitees”) from and against any and all liability, damage, loss, cost, or expense (including reasonable attorney’s fees and expenses of litigation) (collectively, the “Losses”) arising or resulting from any claims made or suits brought by Third Parties to the extent such Losses arise or result from (a) the breach of any MRKDG representations, warranties, or covenants hereunder; (b) the gross negligence or willful misconduct of any MRKDG Indemnitee in connection with this Agreement in connection with the performance of MRKDG’s obligations or exercise of MRKDG’s rights under this Agreement; and (c) the conduct of the Existing Clinical Trials, except to the extent such Losses arise from any claims for which Company is obligated to indemnify MRKDG Indemnitees in Section 10.2.

10.2 Indemnification by Company. Company shall defend, indemnify, and hold harmless MRKDG, its Affiliates, directors, employees, and agents (collectively, the “MRKDG Indemnitees”) from and against any and all Losses arising or resulting from any claims made or suits brought by Third Parties to the extent such Losses arise or result from (a) the gross negligence or willful misconduct of Company or its Affiliates or its Sublicensees and its or their respective directors, officers, employees, and agents, in connection with the performance of Company’s obligations or exercise of Company’s rights under this Agreement; (b) a breach of any of Company representations, warranties, or covenants hereunder (c) the activities that are actually conducted by or on behalf of Company, its Affiliates, or its Sublicensees, in particular the handling and storage by or on behalf of Company, its Affiliates, or its Sublicensees of any chemical agents or other compounds for the purpose of conducting Research or Development by or on behalf of Company, its Affiliates, or its Sublicensees, including any product liability, personal injury, property damage, or other damage caused thereby; or (d) any infringement of Patent Rights of any Third Party by Company, its Affiliates, or its Sublicensees with respect to any Research, Development, or Commercialization on any Product anywhere in the world or with respect to any other activity performed under this Agreement, except to the extent such Losses arise from any claims for which MRKDG is obligated to indemnify Company Indemnitees in Section 10.1.

10.3 Procedure. A Party seeking indemnification under this Article 10 (the “Indemnified Party”) shall give prompt written notification to the other Party (the “Indemnifying Party”) of the claim for which indemnification may be sought (it being understood and agreed, however, that the failure by a Party to give notice of such claim as provided in this Section 10.3 shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually prejudiced as a result of such failure to give notice). Within [*] after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the other Party, assume control of the defense of such claim with counsel reasonably satisfactory to the Indemnified Party. If the Indemnifying Party does not assume control of such defense, the Indemnified Party shall control such defense and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party shall reimburse the Indemnified Party for all costs and expenses, including reasonable attorneys’ fees and disbursements, incurred by the Indemnified Party in defending itself within [*] after receipt of any invoice therefor from the Indemnified Party. The Party not controlling such defense may participate therein at its own expense; provided, that if the Indemnifying Party assumes control of such defense and the Indemnified Party in good faith concludes, based on written advice from outside counsel, that the Indemnifying Party and the Indemnified Party have conflicting interests with respect to such claim sufficiently adverse to make unadvisable the representation by the same counsel of both Parties under Applicable Laws, ethical rules or equitable principles, the Indemnifying Party shall be responsible for the reasonable fees and expenses of a single counsel to the Indemnified Party in connection therewith. The Party controlling such defense shall keep the other Party advised of the status of such claim and the defense thereof and shall consider recommendations made by the other Party with respect thereto. The Indemnifying Party shall not agree to any settlement of such claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party, without the prior written consent of the Indemnified Party.

28

10.4 Insurance.

(a) Coverage. As of the Effective Date and at any time thereafter during the Term, each Party shall obtain and maintain [*], insurance [*]. It is understood and agreed that this insurance shall not be construed to limit either Party’s liability with respect to its indemnification obligations hereunder.

(b) Post-Termination Obligations. Company will maintain the insurance required under Section 10.4(a) beyond the expiration or termination of this Agreement for a reasonable period after the period during which Company or its Affiliates or Sublicensees were Developing or Commercializing the Compound or Product, which in no event will be less than [*].

EXCEPT FOR CLAIMS OF A THIRD PARTY THAT ARE SUBJECT TO INDEMNIFICATION UNDER THIS ARTICLE 10, NEITHER PARTY NOR ANY OF ITS AFFILIATES WILL BE LIABLE TO THE OTHER PARTY OR ITS AFFILIATES FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE, OR OTHER INDIRECT DAMAGES OR LOST OR IMPUTED PROFITS OR ROYALTIES, LOST DATA, OR COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, WHETHER LIABILITY IS ASSERTED IN CONTRACT, WARRANTY, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY, CONTRIBUTION, OR OTHERWISE ARISING OUT OF, OR RELATING TO, THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREIN OR ANY BREACH HEREOF, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE. NOTHING IN THIS AGREEMENT SHALL LIMIT EITHER PARTY FROM SEEKING OR OBTAINING ANY REMEDY AVAILABLE UNDER LAW FOR ANY BREACH OF BY THE OTHER PARTY OF ITS CONFIDENTIALITY AND NON-USE OBLIGATIONS UNDER ARTICLE 8.

The Parties agree that they intend the following rights to extend to the maximum extent permitted by law, including for purposes of the Code or any comparable provision of any Applicable Law in any other jurisdiction: (a) the right of access to any intellectual property (including all embodiments thereof) of the licensor, or any Third Party with whom the licensor contracts

ARTICLE 12 DATA PRIVACY

12.1 Compliance with Data Protection Laws.

(a) General Compliance.

(i) The Parties acknowledge that the Regulation (EU) 2016/679 (“EU GDPR”) will be or can become applicable to the processing of Personal Data in connection with this Agreement and agree to process any Personal Data in accordance with Applicable Laws. Any Personal Data that(A) either Party received from the other Party, and/or (B) is processed by a Party as part of its obligations under this Agreement shall be processed by that Party only in strict compliance with Applicable Laws and exclusively for the purposes of this Agreement. Each Party shall ensure that all Persons entrusted with the processing of Persona Data are under the same obligation.

(ii) Each Party will treat the Personal Data that is processed in the performance of its obligations in strict confidence and will only store such Personal Data for as long as it is necessary in connection with this Agreement or otherwise required by Applicable Laws.

(b) Exchange of Personal Data Between the Parties.

(i) The Parties acknowledge and agree that where they process Personal Data for the purposes of this Agreement, to the extent relevant under the EU GDPR, each Party will act as an independent controller and will be solely responsible for its own processing activities.

(ii) If and to the extent Personal Data is processed by or on behalf of MRKDG by Company, or by or on behalf of Company by MRKDG, so that Company or MRKDG, as the case may be, is acting as a “processor” according to the EU GDPR, a processing agreement shall be agreed in writing by the Parties in order to comply with the requirements under the EU GDPR.

33

(iii) If and to the extent that the Parties jointly determine the purposes and means of processing of Personal Data, acting as “Joint Controllers” according to the EU GDPR, the Parties shall agree in writing on a Joint Controller agreement that determines their respective responsibilities for compliance with the EU GDPR and that shall apply in addition to the other provisions of this Clause.

(c) Cross-Border Transfer. Any transfer of Personal Data that originates in the European Union to a third country outside the European Union in connection with the performance of a Party’s obligations under this Agreement shall only be made in accordance with Articles 44 to 50 of the EU GDPR and other Applicable Laws. The Parties agree to implement appropriate safeguards in accordance with Article 46 of the EU GDPR where necessary for the transfer of Personal Data for the purposes of the collaboration under this Agreement; this includes the obligation to enter into standard data protection clauses adopted by the European Commission in accordance with the examination procedure referred to in Article 93 (2) of the EU GDPR where necessary.

(d) Data Processing. As at the Effective Date, it is the Parties’ mutual understanding that neither Party will act as Personal Data processor. Should the Processing (as such term is used in the EU GDPR) of Personal Data occur, the following shall apply:

(i) Where one Party consents to subcontracting by the other Party and if the Third Party contractor has access to Personal Data that is subject to this Agreement, the engaging Party shall appoint the Third Party contractor as a data processor under a contract which shall comply with the EU GDPR and shall ensure that the Third Party contractor complies with the engaging Party’s obligations under this Clause, including, without limitation, entering into EU standard contractual clauses (if and to the extent required).

(ii) Where a Party is performing services under this Agreement as Processor (as such term is used in the EU GDPR), such Party shall promptly notify the other Party in writing after becoming aware of any breach of security leading to the accidental or unlawful destruction, loss, alteration, unauthorized disclosure of, or access to, Personal Data subject to this Agreement (the “Data Breach”). Either Party may then request from the other Party further reasonable information about the Data Breach, including a reasonably detailed description of the Data Breach and the categories of Personal Data affected by the Data Breach, and will work together to identify a root cause of, and to remediate such Data Breach. In furtherance of the foregoing, where (a) MRKDG becomes aware of a Data Breach, MRKDG will send an email to [*].notifying Company without undue delay, and (b) where Company becomes aware of a Data Breach, Company will send an email to [*] notifying MRKDG without undue delay.

12.2 Data Privacy Audits. Each Party shall have the right during the Term, and for a period of [*] following termination of this Agreement, to conduct an investigation and audit of the other Party’s activities, books and records, to the extent they relate to that other Party’s performance under this Agreement, to verify compliance with the terms of this Article 12; provided, however, that such books and records may not be audited more than once per Calendar Year and that such investigation or audit shall be conducted during normal business hours, upon reasonable prior notice and performed at the sole and exclusive expense of the auditing Party. The other Party shall cooperate fully with such investigation or audit, the scope, method, nature and duration of which shall be at the sole reasonable discretion of the auditing Party.

34

further acknowledges and ensures that it and its Affiliates, sublicensees, or subcontractors are familiar with the provisions of the United States Foreign Corrupt Practices Act, the UK Bribery Act, and applicable local bribery and corruption laws, and shall not take or permit any action that will either constitute a violation under, or cause the other Party to be in violation of, the provisions of the United States Foreign Corrupt Practices Act, the UK Bribery Act, or other equivalent or applicable local bribery and corruption law (collectively, “Improper Conduct”). In addition to any other rights a Party may have under this Agreement, if a Party notifies the other Party of, or if the other Party otherwise has a reasonable suspicion of, the occurrence of Improper Conduct, the Party may inspect or have inspected by an independent auditor the premises, books, and records of the other Party relevant to Improper Conduct for the purpose of ensuring compliance with its obligations under the preceding sentence.

For clarity, the foregoing means that each Party may designate an Affiliate or subcontractor to perform its obligations hereunder or to be the recipient of the other Party’s performance obligations hereunder.

13.6 Further Actions. Each Party agrees to execute, acknowledge, and deliver such further instruments and to do all such other acts as may be necessary or appropriate to carry out the purposes and intent of this Agreement.
