                Certain confidential information contained in this document, marked by [**], has been omitted because

                  ADC Therapeutics SA (ADCT) has determined that the information (i) is not material and

                  (ii) would likely cause competitive harm to ADC Therapeutics SA (ADCT) if publicly disclosed.

              


      

      
        


    

    2.2           Sublicenses.  Licensee shall have the right to sublicense the rights granted under Section
      2.1 to Affiliates and Third Parties through multiple tiers. All sublicenses shall be consistent with the terms and conditions of this Agreement, and in the case of sublicenses to Affiliates or Third Parties, Licensee shall remain responsible for such
      Affiliate’s or Third Party’s compliance with all obligations under this Agreement applicable to such Affiliate or Third Party. For clarity, no grant of any sublicense to a Third Party or an Affiliate shall relieve Licensee of its obligations
      hereunder. Licensee shall obtain approval from MedImmune  for any license to a Third Party, which approval shall not be unreasonably withheld.

     

    2.3            Selection of Targets.  Licensee recognizes that ADCP and its Affiliates are party to certain
      agreements prior to the Original Execution Date (the “Pre-Existing Agreements”). The licenses granted in this Agreement shall be explicitly subject to the rights conveyed in the Pre-Existing Agreements and
      agreements that may be entered into by MedImmune  and its Affiliates after the Original Execution Date. Accordingly, in further consideration for the licenses granted herein, Licensee shall adhere to the following procedures for selecting Approved
      Targets for inclusion under Section 2.1 of this Agreement. Notwithstanding any other provision of this Agreement there can be no more than eleven (11) Approved ADC Targets and ten (10) Approved Non-ADC Targets at any time. For the avoidance of doubt,
      in the event Licensee develops an ADC Drug Reagent and a Non-ADC Drug Reagent against the same Approved Target, such Approved Target will be counted as both an Approved ADC Target and an Approved Non-ADC Target.

     

    2.3.1           Approval of Targets.  The Parties agree that as of the Original
      Execution Date, the Targets listed in Exhibit 2.3.1 were Approved ADC Targets of which the seven (7) Approved Targets listed in Part 1 were subject to ADC Evaluation Licenses and the two (2) Approved Targets listed in Part 2 were subject to ADC
      Commercial Licenses. If Licensee wished to obtain approval for any other Target for any additional Evaluation License or to replace an Approved Target that was the subject of a Commercial License as permitted by this Agreement, it was obligated to
      provide written notice to Harrison, Goddard and Foote. The Parties further agree that as of 7 April 2016, the eleven (11) Targets listed in Part 3 of Exhibit 2.3.1 are Approved ADC Targets subject to ADC Commercial Licenses and the ten (10) Approved
      Targets listed in Part 4 are Approved Non-ADC Targets subject to ADC Commercial Licenses. If Licensee wishes to replace an Approved Target that is the subject of a Commercial License as permitted by this Agreement, it shall provide written notice to
      Clinical Technology Transfer Group, PLLC (“CTTG”), which notice (an “Approval Request Notice”) shall identify the requested Target and specify whether ADCT wishes to
      pursue such Target as an ADC Target, a Non-ADC Target or both an ADC Target and a Non-ADC Target, and this Section 2.3.1 shall apply:

                  ADC Therapeutics SA (ADCT) has determined that the information (i) is not material and

                  (ii) would likely cause competitive harm to ADC Therapeutics SA (ADCT) if publicly disclosed.

              


      

      
        


    

    

    

    2.3.1.1     Within fourteen (14) days of its receipt of the Approval Request Notice required in Section 2.3.1, MedImmune shall inform Licensee in writing
      as to whether the requested Target is available for inclusion under the license granted above in Section 2.1. Any such request must be made in writing to CTTG (or such other Third Party as MedImmune may appoint and notify to the other Parties) and
      must identify the proposed replacement Target. CTTG may deny, at its sole discretion, inclusion of a requested Target under the license granted under Section 2.1 only if ADCP or MedImmune or its Affiliates (a) has an internal program directed at
      researching, developing or selling ADC Drug Reagents or Non-ADC Drug Reagents against the requested Target; or (b) has granted non-exclusive or exclusive rights (or options to obtain such rights) to any ADC Drug Reagent or Non-ADC Drug Reagent or to
      undertake such a program, in either case against such Target, to a Third Party in an agreement executed prior to the notice provided by Licensee under Section 2.3.1, in either case as shown by ADCP or MedImmune’s (or their respective Affiliates’)
      written records (which may be redacted pursuant to any obligation of confidentiality entered into by ADCP or MedImmune (or their respective Affiliates)), such activities or licence ((a) or (b)) a “Pre-Existing
        Restriction”). ADCP and MedImmune shall be entitled to add all such unavailable Targets on MedImmune’s register of Targets maintained by CTTG (or other appointee). If the proposed Target is subject to a Pre-Existing Restriction ADCT shall
      have the right to propose another Target and the above procedure shall be repeated.

     

    2.3.1.2    In the event that there is no Pre-Existing Restriction, then the requested Target shall be an Approved ADC Target, an Approved Non-ADC Target,
      or both an Approved ADC Target and an Approved Non-ADC Target (as requested in the Approval Request Notice) commencing on expiration of such fourteen (14) days’ of its receipt of such notice (the “Approval Date”).

     

    2.3.1.3    For the avoidance of doubt, if CTTG denies inclusion of a requested Target under Section 2.3.3.1 pursuant to the requirements of Section
      2.3.3.1 above, then such Target shall not be an Approved Target and Licensee shall not be licensed under the Licensed Intellectual Property for any ADC Drug Reagent or Non-ADC Drug Reagent against such Target.

     

    2.3.2          Evaluation.  With respect to each such Evaluation License, ADCT shall
      have a period of [**] from the Original Execution Date or, if later, the Approval Date of the applicable Approved Target, to evaluate such Approved Target. With respect to each such Evaluation License, prior to the end of such [**] period, ADCT shall
      on written notice to MedImmune either (a) elect to take an ADC Commercial License and/or Non-ADC Commercial License, as applicable, for the applicable Approved Target whereupon the Evaluation License with respect to such Approved Target shall expire
      and the number of available Evaluation Licenses shall be reduced by one (1); or (b) elect to replace such Approved Target with a new Target for evaluation, in which case ADCT shall seek approval for such new Target in accordance with Section 2.3.1
      and subject to such approval, ADCT shall have a [**] ADC Evaluation License and/or a Non-ADC Evaluation License (as requested in the Approval Request Notice) for such Approved Target commencing on the Approval Date for such Approved Target. At the
      end of such [**] Evaluation Period, ADCT may elect to take an ADC Commercial License and/or Non-ADC Commercial License, as applicable, for such Approved Target. For clarity the Approved Target for each Evaluation License may be replaced only once and
      at any one time there may not be in aggregate more than (a) eleven (11) Approved Targets subject to an ADC Evaluation License or ADC Commercial License, and (b) ten (10) Approved Targets subject to an Non-ADC Evaluation License or Non-ADC Commercial
      License. If with respect to any Approved Target, ADCT fails to make any election pursuant to this Section 2.3.2 at the end of such [**] or [**] period, all licenses with respect to such Approved Target shall terminate.

      time up to the [**] anniversary of the Original Execution Date, replace the Approved Target of any Commercial License with another Approved Target (selected in accordance with Section 2.3.1) provided that in aggregate the number of replacements for
      all (a) ADC Commercial Licenses shall not exceed eleven (11), and (b) Non-ADC Commercial Licenses shall not exceed ten (10).

     

    2.3.4         Rejected Targets.  If at the end of the applicable evaluation period the Evaluation License for an
      Approved Target is not converted into a Commercial License, or the Approved Target of any Commercial License is replaced (each such Target a “Rejected Target”), ADCT shall no longer be licensed under this
      Agreement with respect to such Rejected Target or any ADC Drug Reagent or Non-ADC Reagent against such Target. ADCT shall cease all work on such Rejected Target and return all materials related to such Rejected Target provided by MedImmune  to
      MedImmune. No Rejected Target may be reselected for an Evaluation License or a Commercial License.

     

    2.3.5          Reporting.  ADCT shall, within 30 days after the end of each calendar year, (i) notify ADCP and
      MedImmune  in writing of the Approved ADC Targets and Approved Non-ADC Targets subject to ADC Commercial Licenses and (ii) confirm in writing whether any Reporting Event has occurred during such calendar year. For purposes hereof, “Reporting Event” shall mean (i) the first dosing of the first human participant in a Phase II clinical trial of a Licensed Product, (ii) the first dosing of the first human participant in a Phase III clinical trial
      of a Licensed Product, and (iii) the first regulatory approval in the United States of America of a Licensed Product.

     

    2.4            Reservation of Rights.  Subject to Section 6.2(h) below, MedImmune reserves all rights not specifically granted under
      this ARTICLE 2.

     

    2.5        Diligence.  With respect to each Evaluation License and Commercial License, ADCT shall use Diligent Efforts to (a) develop
      and commercialize at least one (1) product, and (b) file an IND for one (1) product within (i) [**] after the Original Execution Date, or (ii) [**] after formal designation of a replacement Approved Target pursuant to the process set forth in Section

    ARTICLE 3

    RESEARCH AND DEVELOPMENT AND INTELLECTUAL PROPERTY

     

    3.1           Prosecution and Maintenance of Licensed Patents.  Subject to Section 3.1.1, MedImmune shall,
      at its sole discretion, have the right to prosecute and maintain the Licensed Patents with reasonable commercial care taking into account the value of such Licensed Patents to ADCT. For any filings made after the Effective Date, MedImmune shall file
      national phase applications in Europe, US, Australia, Brazil, Canada, India, China, Japan and Russia with European validation in the UK, Germany, France, Spain, Italy, the Netherlands. ADCT may request that MedImmune file in countries other than
      those listed above (“Additional Filings”), but must do so in writing at least sixty (60) days prior to the deadline for filing on a country-by-country basis, the cost of such Additional Filings being borne by
      ADCT (unless such cost was already reimbursed by another MedImmune licensee). MedImmune agrees to maintain the pendency of the Licensed Patents for the term of this Agreement except to the extent that a patent application in the Licensed Patents is
      finally rejected by an administrative body of competent jurisdiction from which no appeal or further appeal can be taken. Notwithstanding the foregoing, if MedImmune wishes to abandon any of the Licensed Patents, MedImmune shall seek written
      authorization from ADCT, which authorization shall not unreasonably be withheld taking into account the value of such Licensed Patent(s) to ADCT in the context of this Agreement. MedImmune shall (i) keep ADCT reasonably informed with respect to the
      issuance of Licensed Patents, and (ii) keep ADCT reasonably informed with respect to the abandonment of any patent or patent application included in the Licensed Patents. With respect to the Development Patents included within the Licensed Patents,
      MedImmune shall (unless the prosecution is controlled by ADCT) (a) provide ADCT with copies of and an opportunity to review and comment upon the text of the applications relating to such Development Patents at least ten (10) days before filing, (b)
      provide ADCT with a copy of each submission made to and document received from a patent authority, court or other tribunal regarding any such Development Patents promptly after making such filing or receiving such document, including a copy of each
      application as filed together with notice of its filing date and application number, (c) keep ADCT advised of the status of all material communications, actual and prospective filings or submissions regarding such Development Patents, and will give
      ADCT copies of and an opportunity to review and comment on any such material communications, filings and submissions proposed to be sent to any patent authority or judicial body; and (d) incorporate ADCT’s reasonable comments on such communications,
      filings and submissions.

     

    3.1.1         Prosecution and Maintenance of Development Patents.  With respect to the
      Development Patents owned by ADCT or jointly owned by ADCT and MedImmune pursuant to Sections 3.1.3(b) and (c) below, ADCT shall at its sole discretion, have the right to prosecute and maintain such Development Patents using a patent agent/attorney
      reasonably approved by MedImmune (for example, the same patent agent/attorney prosecuting patent applications on behalf of MedImmune in the PBD space) provided that ADCT shall (a) provide MedImmune with copies of and an opportunity to review and
      comment upon the text of the applications relating to such Development Patents at least ten (10) days before filing, (b) provide MedImmune with a copy of each submission made to and document received from a patent authority, court or other tribunal
      regarding any such Development Patents promptly after making such filing or receiving such document, including a copy of each application as filed together with notice of its filing date and application number, (c) keep MedImmune advised of the
      status of all material communications, actual and prospective filings or submissions regarding such Development Patents, and will give MedImmune copies of and an opportunity to review and comment on any such material communications, filings and
      submissions proposed to be sent to any patent authority or judicial body; and (d) if MedImmune reasonably believes that such communication, filing or submission will have a detrimental effect on its commercial interests with respect to PBDs, then
      MedImmune shall have the right to require ADCT to amend its communication, filing or submission prior to it being transmitted such as to prevent such detrimental effect, unless ADCT can reasonably establish that no such detrimental effect will occur.

    3.1.2         Costs and Fees.  Except as provided in this Section 3.1, MedImmune will
      pay any costs and fees for prosecution and maintenance of the Licensed Patents. ADCT will pay any costs and fees for prosecution and maintenance of the Development Patents described in Section 3.1.2(c).

     

    3.1.3         Development IP.  Any Patents having claims conceived during the course of work undertaken by ADCT in
      exercise of its rights under this Agreement (the “ADCT Development Work”) including, without limitation the patents and applications on Exhibit 3.1.2 (together the “Development
        Patents”) shall be owned as follows:

     

    (a)          Any Development Patents to the extent claiming a PBD or any PBD attached to an antibody other than a Licensed Antibody; and/or methods of making
      or using any of the foregoing shall be solely owned by MedImmune, regardless of inventorship. ADCT agrees to assign, and does hereby assign, the entire right, title and interest in and to any Development Patents under this Subsection to MedImmune;
      and to execute or cause to be executed all necessary documents in relation thereto.

     

    (b)          Any Development Patents to the extent claiming a Licensed Antibody against an Approved Target shall be solely owned by ADCT, regardless of
      inventorship. MedImmune agrees to assign, and does hereby assign, the entire right, title, and interest in and to any Development Patents under this Subsection to ADCT; and to execute or cause to be executed all necessary documents in relation
      thereto. For the avoidance of doubt, ADCT shall have no right to any claim in any Development Patent to a PBD or any methods of making or using the same that is/are conceived and/or reduced to practice during the course of ADCT Development Work
      except as provided in Subsection (c) below.

     

    (c)          Any Development Patent to the extent claiming an ADC Drug Reagent, and/or methods of making or using the ADC Drug
      Reagent shall be jointly owned by the Parties; however (i) MedImmune shall have no right to exploit such Patent during the Term, (ii) ADCT shall have the exclusive right to exploit such Patent during the Term, and (iii) MedImmune hereby consents to
      ADCT’s exploitation during the Term without any duty of accounting except as provided in this Agreement. Subsequent to the Term, the Parties shall provide consent to each other to allow exploitation of any Patent under this Subsection without any
      duty of accounting. Each Party agrees to assign, and does hereby assign, a joint interest to the other Party to any Development Patents under this Subsection to the extent necessary to effect the purposes hereof; and to execute or cause to be
      executed all necessary documents in relation thereto.

                Certain confidential information contained in this document, marked by [**], has been omitted because

                  ADC Therapeutics SA (ADCT) has determined that the information (i) is not material and

                  (ii) would likely cause competitive harm to ADC Therapeutics SA (ADCT) if publicly disclosed.

              


      

      
        


    

    (d)           The Parties agree that no single Development Patent shall contain any two or more of the following: (i) claims directed to a PBD, or any PBD
      attached to an antibody that is not a Licensed Antibody against an Approved Target, (ii) claims directed to a Licensed Antibody against an Approved Target, and (iii) claims directed to an ADC Drug Reagent. The Parties agree that such claims shall be
      made in separate patent applications, with ownership determined as provided in Subsections 3.1.2(a), 3.1.2(b), and 3.1.2(c).

     

    (e)           The ownership of any Development Patents under this Section that do not fall into Subsection 3.1.2 (a), Subsection 3.1.2 (b), or Subsection and
      3.1.2 (c) shall be determined under U.S. patent law.

     

    (f)        In the event that any claim in the Development Patents is rejected under the judicially-created doctrine of obviousness-type double patenting in
      the United States with respect to another of the Development Patents, the Parties agree to reasonably cooperate in obviating such rejection. For the avoidance of doubt, any Patent conceived by a Third Party otherwise in connection with this Agreement
      and in-licensed to any Party is not a Development Patent.

     

    3.1.4          Rights to Data.  Any data generated by ADCT using the Licensed Intellectual Property in conceiving
      and/or reducing to practice a PBD conjugated to a targeting agent shall be provided to MedImmune and may be used by MedImmune in prosecuting its own intellectual property and/or for general business purposes; provided that (a) such data must be
      “anonymized” as reasonably required by ADCT for confidentiality purposes; and (b) any use of such “anonymized” data shall be subject to the obligations to have such use reviewed as provided in Section 5.2 below (even if the use is not a publication
      or disclosure as described in such section, but such Section 5.2 shall also apply to any use by MedImmune in connection with prosecuting MedImmune’s own intellectual property).

     

    3.2            Non-Solicitation.  The Parties agree that for so long as MedImmune Limited or its Affiliates is providing services to
      ADCT in connection with ADCT Development Work and for [**] thereafter, neither ADCT or MedImmune shall directly or indirectly solicit (other than through a general solicitation to which an individual employee responds or where the individual makes
      the initial approach to the hiring Party) for employment any scientist, member of management or any other individual who is employed by MedImmune or any of its Affiliates.

     

    3.3            Enforcement Rights for Infringement by Third Parties.

     

    3.3.1         Notice.  Each of ADCP, MedImmune and ADCT shall promptly notify, in writing, the other Party upon
      learning of any actual or suspected infringement of the Licensed Intellectual Property (“Infringement”), or of any claim of invalidity, unenforceability, or non-infringement of the Licensed Intellectual
      Property. The notifying Party shall provide to the other Party all evidence in such Party’s possession pertaining to the actual or suspected infringement, or claim of invalidity, unenforceability, or non-infringement that it can disclose without
      breach of a pre-existing obligation to a Third Party or waiver of a privilege.

    3.3.2       Enforcement Actions.  MedImmune shall have the sole right at its sole expense and in its sole discretion
      to control the enforcement of the Licensed Patents (other than the ADCT Development Patents set forth in Sections 3.1.2 (b) and 3.1.2 (c)) against infringers. In any enforcement action filed by MedImmune under this Section, ADCT agrees to be joined
      as a party, at MedImmune’s expense, if a court of competent jurisdiction determines that it is necessary to do so. If ADCT notifies MedImmune of the alleged infringing activity by a Third Party pursuant to this Section and MedImmune in good faith
      does not believe that the Third Party is infringing any of the Licensed Patents, then upon written request of MedImmune and within thirty (30) days following receipt of ADCT’s notice, the Parties shall meet to discuss in good faith the merits of the
      infringement. In the event that the Parties cannot agree as to whether an infringement exists, despite reasonable good faith efforts, the Parties shall agree on an independent patent attorney located in the jurisdiction where the alleged infringement
      is occurring who shall determine whether, in such attorney’s opinion, there is no possibility of literal infringement existing as alleged by ADCT. The independent attorney shall provide its opinion orally to both Parties at the same time (unless the
      Parties mutually agree on a written opinion) and shall have entered into a joint defense or shared interest agreement with both Parties in advance of the engagement to protect work product and attorney-client privilege. The Parties shall share the
      expense of such attorney equally. Such attorney shall: (a) not previously have done any work for MedImmune or ADCT or any of their Affiliates; (b) have at least fifteen (15) years of experience; (c) not be reasonably objected to by either Party if
      such Party reasonably believes that the retention of such independent attorney would be prejudicial to its intellectual property interests; and (d) be subject to obligations of confidentiality no less onerous than those set forth in this Agreement.
      Both Parties shall, within five (5) Business Days of the retention of such attorney, submit the subject Licensed Patents and the identity of the alleged infringing product, and such patent attorney shall review such information and provide the oral
      opinion (unless the parties agree that such opinion shall be in writing) within forty-five (45) days of his or her retention. Unless such attorney determines that there is no possibility of literal infringement as alleged by ADCT, then MedImmune
      shall be obligated to enforce the subject Licensed Patent(s); otherwise MedImmune shall have no further obligation to pursue the matter.

     

    3.3.3          Development Patents.  ADCT shall have the sole right at its sole expense and in its sole discretion
      to control the enforcement of Development Patents under Sections 3.1.2(b) and 3.1.2(c) during the Term. In any enforcement action filed by ADCT under this Section, MedImmune agrees to be joined as a party, at ADCT’s expense, if a court of competent
      jurisdiction determines that it is necessary to do so.

      

    

    3.3.4         Settlement.  The Party controlling any such enforcement action may not settle, or otherwise consent to
      an adverse judgment in, such action that diminishes the rights or interests of the non-controlling Party without the prior express written consent of the non-controlling Party.

     

    3.3.5         Costs and expenses.  The Party controlling any such enforcement shall bear all costs and expenses,
      including but not limited to litigation expenses, related to such enforcement actions.

     

    3.3.6          Damages.  All damages, amounts received in settlement, judgment or other monetary awards recovered in
      an action to enforce the Licensed Patents shall first be applied to reimburse the controlling Party for its reasonable expenses, including attorneys’ fees. Any remainder [**].

                Certain confidential information contained in this document, marked by [**], has been omitted because

                  ADC Therapeutics SA (ADCT) has determined that the information (i) is not material and

                  (ii) would likely cause competitive harm to ADC Therapeutics SA (ADCT) if publicly disclosed.

              


      

      
        


    

    3.3.7          Cooperation.  In any suit to enforce and/or defend the Licensed Patents pursuant to this Section, the
      Party not in control of such suit shall, at the request and expense of the controlling Party, reasonably cooperate and, to the extent possible, have its employees testify when requested and make available relevant records, papers, information,
      samples, specimens, and the like.

     

    3.4            Third Party Infringement Claims.  In the event that a Third Party shall make any claim, give
      notice, or bring any suit or other inter parties proceeding against ADCT or MedImmune, or any of their respective Affiliates or sublicensees or customers, for infringement or misappropriation of any intellectual property rights with respect to
      making, using, selling, offering for sale, or importing any Licensed Product (“Third Party Infringement Claim”), in each case, the Party receiving notice of a Third Party Infringement Claim shall promptly
      notify the other Party and provide all evidence in its possession pertaining to the claim or suit that it can disclose without breach of a pre-existing obligation to a Third Party or waiver of a privilege.

     

    3.4.1          Defense.  The Parties shall consult as to potential strategies to defend against any Third Party
      Infringement Claim, consistent with the overall goals of this Agreement, including by being joined as a party. The Parties shall cooperate with each other in all reasonable respects in the defense of any Third Party Infringement Claim arising out of
      any counterclaim related thereto. Subject to the respective indemnity obligations of the Parties set forth in ARTICLE 7, each Party shall be entitled to defend itself in such suit or inter parties proceeding. Each Party shall reasonably cooperate
      with the other Party in connection with any such defense.

     

    3.4.2          Settlement.  If any such defense under this Section 3.4 would adversely affect one Party’s rights
      under this Agreement or impose a financial obligation upon one Party or grant rights in respect of or affect the validity or enforceability of the Licensed Intellectual Property, then any settlement, consent judgment or other voluntary final
      disposition of such Third Party Infringement Claim shall not be entered into without the written consent of such Party.

     

    3.5             Challenges to Licensed Patents.  In the event that ADCT challenges the validity or enforceability of any Patent within
      the Licensed Patents issued as of the Effective Date (excluding any participation in a proceeding where ADCT is legally compelled to provide information), ADCT agrees that (a) it shall continue to make all payments due under this Agreement while such
      challenge is pending; and (b) [**]. This Section shall not survive any expiration or termination of this Agreement.

     

    3.6           Other Agreements.  The Parties acknowledge that ADCT is subject to a Sublicense Agreement with BZL Biologics LLC dated
      July 12, 2013; a Collaboration and Licence Agreement with VivaMab, a division of BioAtla LLC, dated May 24, 2013; a Collaboration and Supply Agreement with Stem CentRx Inc. dated May 27, 2013; and a Collaboration and License Agreement with Genmab A/S
      dated June 14, 2013. If and to the extent that any provisions of this ARTICLE 3 are contrary to any of ADCT’s obligations or rights in such agreements the Parties shall discuss such potential conflicts and shall co-operate in good faith to implement
      the provisions of this Agreement and those agreements in a manner that avoids any breach of such agreements and where necessary to seek amendments to such agreements to avoid such conflicts.

    ARTICLE 4

    CONFIDENTIALITY

     

    4.1           Non-use and Non-disclosure of Confidential Information.  During the Term, and for a period of
      [**] thereafter, each Party shall (i) except to the extent permitted by this Agreement or otherwise agreed to in writing, keep confidential and not disclose to any Third Party any Confidential Information of any of the other Parties; (ii) except in
      connection with activities contemplated by, the exercise of rights permitted by, in order to further the purposes of this Agreement or otherwise agreed to in writing, not use for any purpose any Confidential Information of the other Parties; and
      (iii) take all reasonable precautions to protect the Confidential Information of the other Parties (including all precautions a Party employs with respect to its own confidential information of a similar nature and taking reasonable precautions to
      assure that no unauthorized use or disclosure is made by others to whom access to the Confidential Information of the Party is granted).

     

    4.2            Exclusions Regarding Confidential Information.  Notwithstanding anything set forth in this ARTICLE 4 to the contrary,
      the obligations of Section 4.1 above shall not apply to the extent that the Party seeking the benefit of the exclusion can demonstrate that the Confidential Information of the disclosing Party:

     

    (a)           was already known to the receiving Party, other than under an obligation of confidentiality, at the time of receipt by the receiving Party;

     

    (b)           was generally available to the public or otherwise part of the public domain at the time of its receipt by the receiving Party;

     

    (c)          became generally available to the public or otherwise part of the public domain after its receipt by the receiving Party other than through any
      act or omission of the receiving Party in breach of this Agreement;

     

    (d)         was received by the receiving Party without an obligation of confidentiality from a Third Party having the right to disclose such information
      without restriction;

     

    (e)            was independently developed by or for the receiving Party without use of or reference to the Confidential Information of the disclosing Party;
      or

     

    (f)            was released from the restrictions set forth in this Agreement by express prior written consent of the disclosing Party.

     

    4.3         Authorized Disclosures of Confidential Information.  Notwithstanding the foregoing, a Party may use and disclose the
      Confidential Information of another Party as follows:

     
      (a)          if required by law, rule or governmental regulation, including as may be required in connection with any filings made with, or by the
        disclosure policies of a major stock exchange; provided that the Party seeking to disclose the Confidential Information of another Party (i) use all reasonable efforts to inform the such Party prior to making any such disclosures and cooperate with
        such Party in seeking a protective order or other appropriate remedy (including redaction) and (ii) whenever possible, request confidential treatment of such information;

       

    

    
      
        	14
	
                Certain confidential information contained in this document, marked by [**], has been omitted because

                  ADC Therapeutics SA (ADCT) has determined that the information (i) is not material and

                  (ii) would likely cause competitive harm to ADC Therapeutics SA (ADCT) if publicly disclosed.

              


      

      
        


    

    (b)           to the extent such use and disclosure is reasonably required in the filing, prosecution, maintenance or publication of any patent application
      or patent on inventions;

     

    (c)         as reasonably necessary to obtain or maintain any regulatory approval, including to conduct preclinical studies and clinical trials and for
      pricing approvals, for any ADC Drug Reagents or Non-ADC Drug Reagents licensed hereunder, provided, that, the disclosing Party shall take all reasonable steps to limit disclosure of the Confidential Information outside such regulatory agency and to
      otherwise maintain the confidentiality of the Confidential Information;

     

    (d)           to take any lawful action that it deems necessary to protect its interest under, or to enforce compliance with the terms and conditions of,
      this Agreement; or

     

    (e)        to the extent necessary, to permitted sublicensees, licensees, collaborators, vendors, consultants, agents, attorneys, contractors and clinicians
      under written agreements of confidentiality at least as restrictive on those set forth in this Agreement, who have a need to know such information in connection with such Party performing its obligations or exercising its rights under this Agreement.
      Further, the receiving Party may disclose Confidential Information to existing or potential acquirers, merger partners, permitted collaborators, licensees and sources of financing or to professional advisors (e.g. attorneys, accountants and
      prospective investment bankers) involved in such activities, for the limited purpose of evaluating such transaction, collaboration or license and under appropriate conditions of confidentiality, only to the extent necessary and with the agreement by
      those permitted individuals to maintain such Confidential Information in strict confidence.

     

    4.4         Terms of this Agreement.  The Parties agree that this Agreement and the terms hereof will be considered Confidential
      Information of Licensee, ADCP and MedImmune but can be shared with potential sublicensees under this Agreement or acquirers to the extent necessary to complete the subject transaction.

     

    4.5           No License.  As among the Parties, Confidential Information disclosed hereunder shall remain the property of the
      disclosing Party. Disclosure of Confidential Information to the other Parties shall not constitute any grant, option or license to the other Parties, beyond those licenses expressly granted hereunder, under any patent, trade secret or other rights
      now or hereinafter held by the disclosing Party.

     

    ARTICLE 5

     PUBLICITY; PUBLICATIONS

     

    5.1           Publicity.  Licensee and MedImmune shall mutually agree upon the form of press release that
      they may issue concerning the execution of this Agreement; such issuance to occur after the Effective Date and at a time to be mutually agreed (such agreement not to be unreasonably withheld or delayed).

                Certain confidential information contained in this document, marked by [**], has been omitted because

                  ADC Therapeutics SA (ADCT) has determined that the information (i) is not material and

                  (ii) would likely cause competitive harm to ADC Therapeutics SA (ADCT) if publicly disclosed.

              


      

      
        


    

    5.2           Publications.  Notwithstanding Section 5.1, all Parties recognize that the publication or
      disclosure of papers, presentations, abstracts or any other written or oral presentations regarding results of and other information regarding the ADC Drug Reagents and Non-ADC Drug Reagents may be beneficial to the Parties, provided that such
      publications or presentations are subject to reasonable controls to protect Confidential Information, the patentability of inventions and other commercial considerations. For the avoidance of doubt, the terms of this Section 5.2 shall not apply to
      patent applications filed by a Party. Accordingly, the following shall apply with respect to papers and presentations proposed for disclosure by any Party (the “Disclosing Party”):

     

    (a)          With respect to any paper or presentation proposed for disclosure by the Disclosing Party which utilizes information generated by or on behalf
      of a Party relating to ADC Drug Reagents or Non-ADC Drug Reagents licensed hereunder (including without limitation any publications containing Confidential Information of any other Party) the other Party (the “Non-Disclosing



        Party”) shall have the right to review and approve any such proposed paper or presentation. The Disclosing Party shall submit to the Non-Disclosing Party the proposed publication or presentation (including, without limitation, posters,
      slides, abstracts, manuscripts, marketing materials and written descriptions of oral presentations) at least thirty (30) calendar days prior to the date of submission for publication or the date of presentation, whichever is earlier, of any of such
      submitted materials. The Non-Disclosing Party shall review such submitted materials and respond to the Disclosing Party as soon as reasonably possible, but in any case within twenty (20) calendar days of receipt thereof. At the option of the
      Non-Disclosing Party, the Disclosing Party shall (a) delete from such proposed publication or presentation any Confidential Information of the Non-Disclosing Party and (b) delay the date of such submission for publication or the date of such
      presentation for a period of time sufficiently long (but in no event longer than sixty (60) calendar days) to permit the Non-Disclosing Party to seek appropriate patent protection. Once a publication has been approved by the Non-Disclosing Party, the
      Disclosing Party may make subsequent public disclosure of the contents of such publication without the further approval of the Non-Disclosing Party; provided, such content is not presented with any new data or information or conclusions and/or in a
      form or manner that materially alters the subject matter therein.

     

    5.3           No Right to Use Names.  Except as expressly provided herein, no right, express or implied, is granted by the Agreement to
      use in any manner the name of “MedImmune”, “Spirogen”, “ADCT”, or any other trade name, symbol, logo or trademark of any Party in
      connection with the performance of this Agreement.

     

    ARTICLE 6

     REPRESENTATIONS

     

    6.1          Mutual Representations and Warranties.  ADCT, ADCP and MedImmune each represents and warrants to each other that as of the
      Effective Date:

     

    

     (a)            it is validly organized under the laws of its jurisdiction of incorporation;

     

    

    
      
        	16
	
                Certain confidential information contained in this document, marked by [**], has been omitted because

                  ADC Therapeutics SA (ADCT) has determined that the information (i) is not material and

                  (ii) would likely cause competitive harm to ADC Therapeutics SA (ADCT) if publicly disclosed.

              


      

      
        


    

    

    (b)            it has obtained all necessary consents, approvals and authorizations of all governmental authorities and other persons or entities required to
      be obtained by it in connection with this Agreement;

     

    (c)            the execution, delivery and performance of this Agreement have been duly authorized by all necessary corporate action on its part;

     

    (d)            it has the legal right and power to enter into this Agreement and to fully perform its obligations hereunder;

     

    (e)          the performance of its obligations will not conflict with such Party’s charter documents or any agreement, contract or other arrangement to
      which such Party is a party; and

     

    (f)          it follows reasonable commercial practices common in the industry to protect its proprietary and confidential information, including requiring
      its employees, consultants and agents to be bound in writing by obligations of confidentiality and non-disclosure, and requiring its employees, consultants and agents to assign to it any and all inventions and discoveries discovered by such
      employees, consultants or agents made within the scope of, and during their employment, and only disclosing proprietary and confidential information to Third Parties pursuant to written confidentiality and non-disclosure agreements.

     

    6.2           MedImmune Additional Warranty.  MedImmune also represents and warrants to Licensee that:

     

    (a)          except as noted in Exhibit 6.2(a), prior to the Novation Date Spirogen Sarl was, and from the Novation Date MedImmune is, the sole and exclusive
      owner, or the exclusive licensee, of all right, title and interest in and to the Licensed Intellectual Property;

     

    (b)           prior to the Novation Date Spirogen Sarl had, and from the Novation Date MedImmune has the legal right and power to extend the rights and
      licenses granted to Licensee hereunder and to transfer the Know-How licensed pursuant to this agreement, including the ADC Drug Reagents and Non-ADC Drug Reagents licensed hereunder, to Licensee;

     

    (c)         prior to the Original Execution Date Spirogen Sarl did not, own or control any intellectual property, other than the Licensed Intellectual
      Property, that would be infringed by Licensee in researching, developing, or commercializing any ADC Drug Reagent or Non-ADC Drug Reagent licensed hereunder;

     

    (d)         neither MedImmune nor Spirogen Sarl has granted any right, license or interest in or to the Licensed Intellectual Property, or any portion
      thereof, that negates the rights granted to Licensee herein;

     

    
      
        	17
	
                Certain confidential information contained in this document, marked by [**], has been omitted because

                  ADC Therapeutics SA (ADCT) has determined that the information (i) is not material and

                  (ii) would likely cause competitive harm to ADC Therapeutics SA (ADCT) if publicly disclosed.

              


      

      
        


    

    (e)           it shall not amend the terms of any Third Party Agreement in any manner that would have a material negative affect on the rights granted by
      MedImmune to Licensee hereunder without Licensee’s prior written consent; and

     

    (f)          as of the Original Execution Date, Spirogen SARL had no knowledge of any threatened or pending actions, lawsuits, claims or arbitration
      proceedings in any way relating to the Licensed Intellectual Property; provided, however, that nothing in this Section 6.2 shall be interpreted as having required Spirogen SARL to have undertaken any inquiries or to have obtained any freedom to
      operate opinion.

     

    (h)           prior to the Novation Date Spirogen Sarl did not, and subsequent to the Novation Date MedImmune will not, enter into
      any agreements with Third Parties, with respect to the Licensed Intellectual Property that would effectively prevent Licensee from exercising its rights under ARTICLE 2 of this Agreement with respect to eleven (11) commercially-relevant Approved ADC
      Targets and ten (10) commercially-relevant Approved Non-ADC Targets. For the avoidance of doubt, MedImmune will not exclusively license PBD or Linker Chemistry in a manner that would effectively prevent Licensee from exercising its rights under
      ARTICLE 2 of this Agreement as described above.

     

    6.3           Disclaimers.  EXCEPT AS OTHERWISE EXPRESSLY STATED IN THIS AGREEMENT, NO PARTY MAKES ANY REPRESENTATION OR WARRANTY OF
      ANY KIND WITH RESPECT TO PATENTS, KNOW-HOW, MATERIALS OR CONFIDENTIAL INFORMATION SUPPLIED BY IT TO ANY OTHER PARTY HEREUNDER, AND EXPRESSLY DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY,
      FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT.

     

    ARTICLE 7

     INDEMNIFICATION

     

    7.1          Indemnification.  Subject to Section 7.2, each Party shall indemnify, defend and hold the other Party, its Affiliates and
      their respective directors, officers, and employees and the successors and assigns of any of the foregoing harmless from and against any and all liabilities, damages, settlements, penalties, fines, costs or expenses (including, without limitation,
      reasonable attorneys’ fees and other expenses of litigation) (collectively, “Loss” or “Losses”) arising, directly or indirectly out of or in connection with any Third
      Party claims, suits, actions, demands or judgments (“Third Party Claims”) resulting from (a) the gross negligence or willful misconduct of such Party under this Agreement, (b) breach by such Party of the
      representations and warranties under Article 6, or (c) in the case of Licensee (its Affiliates and their sublicensees), product liability and infringement claims relating to Licensee (its Affiliates and their sublicensees) development and
      commercialization of an ADC Drug Reagent or Non-ADC Drug Reagent approved by MedImmune  pursuant to Section 2.3 above.

     

    
      
        	18
	
                Certain confidential information contained in this document, marked by [**], has been omitted because

                  ADC Therapeutics SA (ADCT) has determined that the information (i) is not material and

                  (ii) would likely cause competitive harm to ADC Therapeutics SA (ADCT) if publicly disclosed.

              


      

      
        


    

    7.2           Procedure.  If a Party intends to claim indemnification under this Agreement (the “Indemnitee”), it shall promptly notify the other Party (the “Indemnitor”) in writing of such alleged Loss. The Indemnitor shall have the right to control the defense thereof
      with counsel of its choice as long as such counsel is reasonably acceptable to Indemnitee. Any Indemnitee shall have the right to retain its own counsel at its own expense for any reason, provided, however, that if the Indemnitee shall have
      reasonably concluded, based upon a written opinion from outside legal counsel, that there is a conflict of interest between the Indemnitor and the Indemnitee in the defense of such action, in each of which cases the Indemnitor shall pay the fees and
      expenses of one law firm serving as counsel for the Indemnitee). The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any Third Party Claims covered by this
      Agreement. The obligations of this  ARTICLE 7 shall not apply to any settlement of any Third Party Claims if such settlement is effected without the consent of both Parties, which shall not be unreasonably withheld or delayed. The failure to deliver
      written notice to the Indemnitor within a reasonable time after the commencement of any such action, to the extent prejudicial to its ability to defend such action, shall relieve the Indemnitor of any obligation to the Indemnitee under this Section
      7.2. It is understood that only Licensee and MedImmune may claim indemnity under this Agreement (on its own behalf or on behalf of its Indemnitees), and other Indemnitees may not directly claim indemnity hereunder.

     

    7.3           Insurance.  Subject to Section 7.4, Licensee shall, at its sole expense, obtain and maintain
      the following insurance on its own behalf, with insurance companies having an A. M. Best Rating of “A-, VII” or better:

     

    (a)           From the initiation of the first clinical trial for a Licensed Product until the date three (3) years after the last dosing of a human subject
      under the last clinical trial for a Licensed Product, Licensee shall maintain coverage for each such clinical trial in accordance with the national regulation of each country in which it runs a clinical trial but in any event in an amount not less
      than (i) [**] per occurrence and [**] annual aggregate for any Phase I clinical trial, and (ii) [**] per occurrence and [**] annual aggregate for any Phase II Trial or Phase III Trial;

     

    (b)           During the Term, Licensee shall maintain comprehensive or commercial general liability insurance (contractual liability included) with limits
      of at least: (i) each occurrence, [**]; (ii) personal and advertising injury, [**]; and (iii) general aggregate (commercial form only), [**].

     

    (c)            Such insurance shall name MedImmune  as an additional insured.

     

    (d)           Licensee shall furnish MedImmune  with certificates of insurance showing compliance with all requirements set forth in this Section 7.3. Such
      certificates shall: (i) indicate that MedImmune  has been endorsed as an additional insured under the coverage referred to above; and (ii) include a provision that the coverage shall be primary and shall not participate with nor shall be excess over
      any valid and collectable insurance or program of self-insurance carried or maintained by MedImmune. Licensee shall notify MedImmune  within thirty (30) days of any change in the terms of such insurance from those set forth in the most recent
      certificate of insurance provided to MedImmune  pursuant to this Section 7.3. The coverage and limits referred to above shall not in any way limit the liability of Licensee hereunder.

    7.4           Election to Self-Insure.  In the event that Licensee or any sublicensee of Licensee or any
      successor-in-interest of Licensee, is an entity which, together with its Affiliates, has worldwide revenues from pharmaceutical sales in excess of [**] per year, the obligations set forth in Section 7.3, above, shall not apply with respect to such
      entity, if such entity notifies MedImmune  in writing that it elects to provide coverage through a commercially reasonable program of self-insurance; provided, however, that the obligations set forth in Section 7.3, above, shall resume with respect
      to such entity and its Affiliates, or successor-in-interest and its Affiliates, if such program of self-insurance is terminated or discontinued for any reason.

      

    

    7.5           Limitation of Damages.  NO PARTY HERETO WILL BE LIABLE FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR
      PUNITIVE DAMAGES, INCLUDING LOST PROFITS, ARISING FROM OR RELATING TO THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF SUCH DAMAGES, EXCEPT IN RESPECT OF ANY BREACH OF A PARTY’S OBLIGATIONS UNDER ARTICLE 4 OR INDEMNIFICATION OBLIGATIONS UNDER THIS 
      ARTICLE 7 FOR CLAIMS OF THIRD PARTIES.

     

    ARTICLE 8

    TERM AND TERMINATION

     

    8.1           Term.  The term of this Agreement (the “Term”) shall commence on the Effective
      Date and will terminate on the date of expiration of the last Evaluation License or if on such date there are one or more Commercial Licenses in force, on a Commercial License-by-Commercial License basis on the date of the last to expire of the
      Licensed Intellectual Property that Covers a product being exploited pursuant to such license.

     

    8.2           Termination.  This Agreement, including the licenses granted herein, shall terminate upon (a) material breach of any
      provision in this Agreement by Licensee that is not cured within [**] written notice thereof.

     

    ARTICLE 9

     DISPUTE RESOLUTION

     

    9.1           Disputes.  The Parties agree to use their reasonable efforts to resolve any dispute arising
      out of this Agreement by amicable negotiation. If any dispute arising out of this Agreement, including validity, breach, or termination thereof, cannot be resolved within thirty (30) days after notice of such dispute, then such dispute shall be
      settled by arbitration in accordance with the Swiss Rules of International Arbitration of the Swiss Chambers of Commerce (“the Rules”) in force on the date when the notice of arbitration is submitted in
      accordance with the Rules. The arbitral proceedings shall be conducted in accordance with the Expedited Procedure set forth in Section 42, Paragraph 1, of the Rules. The number of arbitrators shall be [**]. The arbitration shall take place in London,
      UK and shall be conducted in English.

    9.2           Interim Equitable Relief.  Notwithstanding anything to the contrary in this Section 9.2, in
      the event that a Party reasonably requires relief on a more expedited basis than would be possible pursuant to the procedure set forth in this ARTICLE 9, such Party may seek a temporary injunction or other interim equitable relief in a court of
      competent jurisdiction pending the ability of the arbitrator to review the decision under this Section 9.2. Such court shall have no jurisdiction or ability to resolve Disputes beyond the specific issue of temporary injunction or other interim
      equitable relief.

     

    9.3           Protective Orders; Arbitrability.  At the request of any Party, the arbitrator shall enter an appropriate protective
      order to maintain the confidentiality of information produced or exchanged in the course of the arbitration proceedings. The arbitrator shall have the power to decide all questions of arbitrability.

     

    9.4           Subject Matter Exclusions.  Notwithstanding the provisions of Section 9.2, any Dispute not resolved internally by the
      Parties pursuant to Section 9.1 that involves the validity or infringement of a Patent that Covers an ADC Drug Reagent or Non-ADC Drug Reagent (a) that is issued in the United States shall be subject to actions before the United States Patent and
      Trademark Office and/or submitted exclusively to the federal court located in the jurisdiction of the district where any of the defendants reside; and (b) that is issued in any other country shall be brought before an appropriate regulatory or
      administrative body or court in that country, and the Parties hereby consent to the jurisdiction and venue of such courts and bodies.

     

    9.5           Continued Performance.  Provided that this Agreement has not terminated, the Parties agree to continue performing under
      this Agreement in accordance with its provisions, pending the final resolution of any Dispute.

    10.3          Assignment.  No Party may assign, in whole or in part, this Agreement without the prior written consent of the
      non-assigning Parties, such approval not to be unreasonably withheld. Notwithstanding the foregoing, any Party may assign this Agreement to (i) an Affiliate or (ii) any purchaser of all or substantially all of the assets of such Party, or of all of
      its capital stock, or to any successor corporation or entity resulting from any merger or consolidation of such Party with or into such corporation or entity, provided that the party to which this Agreement is assigned expressly agrees in writing to
