ARTICLE 2

RESEARCH PROGRAMS

2.1Research Programs.

(a)Research Plans. The Parties agree to initially collaborate on [***] Research Programs, each in accordance with a Research Plan; provided, however, that in the event that Leap exercises the Extension Option, the Parties will collaborate on an additional [***]. Leap shall nominate one Target for each Research Program by completing a Target Questionnaire and delivering it to Adimab during the Discovery Term. Leap shall nominate [***] and, if Leap exercises the Extension Option, Leap shall nominate the remaining [***] Targets no later than [***]. Upon completion of a Target Questionnaire by ▇▇▇▇, the Parties shall agree to a Research Plan setting forth the expected timeline, budget, and relevant deliverables from initial discovery and from optimization of Program Antibodies. In addition, each Research Plan will set forth the criteria for achieving the technical milestone described in Section 4.2(b) (Technical Milestone), which criteria shall be [***]. Such Research Plan shall be based upon the form of Research Plan attached hereto as Exhibit B, and shall include Adimab’s responsibilities with respect to the discovery and optimization of antibodies with respect to each Target. Each Research Plan shall be agreed upon in writing by the Parties, and each Research Program shall be conducted in accordance therewith. Neither Party is required to perform a Research Program under this

Agreement if the Parties do not mutually agree in writing on Research Plan. Adimab shall not unreasonably withhold its approval of a Research Plan. In the event that Adimab does not approve a Research Plan proposed by ▇▇▇▇ as [***] of such proposal, then the Target contemplated by such Research Plan shall not count in calculating the number of Targets on which the Parties shall collaborate hereunder.

(b)Conduct of Research. Each Party shall use its Commercially Reasonable Efforts to perform the activities assigned to such Party in each Research Plan and to achieve the timeline(s) set forth in such Research Plan. Adimab’s performance obligations under each Research Program shall be contingent upon Leap providing the Leap Materials, if any, set forth in the applicable Research Plan. Such Leap Materials are expected to include Target antigen of suitable quality for performance of the Research Program. Adimab’s obligations with regard to the performance of a particular Research Program shall be subject to the Leap Materials passing Adimab’s quality control standards. Adimab’s obligations with regard to the performance of a particular Research Program shall expire at the end of the applicable Research Term. Both Parties shall have the right to use Third Parties in the performance of its obligations hereunder.

2.2Project Management.

(a)Scientific Research Committee. Promptly after the execution of each Research Plan, the Parties shall form a steering committee consisting of two (2) representatives of each Party (the “Research Committee”) to oversee such Research Plan. The Research Committee’s role is to facilitate communication regarding progress in relation to the Research Programs and the collaboration generally. Either Party may change its Research Committee members upon written notice to the other Party. The Research Committee may meet in person or by teleconference or videoconference. Each Party shall designate one of its Research Committee members as co-chair. The Research Committee shall meet from time to time promptly after the date of a written request by either Party. Additional members representing either Party may attend any Research Committee meeting. The co-chairs shall be responsible for circulating, finalizing and agreeing upon on minutes of each meeting [***] after the meeting date. Upon expiration of the final Research Term, the Research Committee shall be disbanded.

(b)Decision Making. The Research Committee shall operate by [***] solely within the limits specified in this Section 2.2 (Project Management), it being understood that if the co-chairs cannot agree with regards to a specific matter within their decision-making authority, no decision of the Research Committee shall be deemed taken by the Research Committee. The Research Committee shall have the limited authority to amend the Research Plans in a manner not substantially affecting resources required to perform, timing for performance, or success criteria. Except for the limited authority set forth in this Section 2.2 (Project Management), the Research Committee shall not have any decision-making authority and in no event shall the Research Committee shall have the power to amend or waive compliance with this Agreement.

(c)Alliance Managers. Each Party shall designate in writing [***] after signing this Agreement an “Alliance Manager” to be the primary contact for such Party. The Alliance Manager shall be responsible for managing communications between the Parties with respect to a Research Program, including responsibility for scheduling teleconferences and

coordinating Research Committee meetings. Alliance Managers may also be members of the Research Committee.

2.3Reports; Records.

(a)By Adimab. During the applicable Research Term, at the junctures specified in the applicable Research Plan, Adimab shall provide written reports to Leap regarding the Research Plan. Notwithstanding the foregoing or anything express or implied anywhere in this Agreement, Adimab shall not be required to disclose any Adimab Platform Technology or Adimab Platform Technology Improvements to Leap. Adimab shall maintain records, in reasonable scientific and technical detail and in a manner appropriate for patent purposes, which shall be complete and accurate and shall fully and properly reflect all work done and results achieved in the performance of a Research Program. In the event that such records and data include disclosure of Adimab Platform Technology or Adimab Platform Technology Improvements, Adimab may redact those portions that would disclose Adimab Platform Technology or Adimab Platform Technology Improvements prior to any review or inspection by Leap.

(b)By Leap. During the applicable Research Term, at the junctures set forth in the applicable Research Plan, Leap shall provide written reports to Adimab which provide any data Leap is required to provide under the applicable Research Plan.

2.4Use of Adimab Materials. With respect to each Target, Leap shall only use Adimab Materials (a) as is necessary to conduct a Research Program during the Research Term and the Evaluation Term, (b) pursuant to the license granted under Section 3.1(a) (Research License to Leap) of this Agreement while such license is in effect, (c) to generate and test Program-Benefited Antibodies in accordance with Section 9.3 (Commitments Regarding Program-Benefited Antibodies) and (d) in connection with the exercise of its rights under Section 3.2(b). Leap shall not use Adimab Materials for any other purposes. For clarity, this means that, except as specified pursuant to the foregoing sentence, Leap shall not (i) provide Adimab Materials to any Third Party, or (ii) use any Program-Benefited Antibodies or Adimab Materials, or information related thereto (including the sequences thereof), for any purpose other than to research and develop antibodies that will be milestone- and royalty-bearing to Adimab hereunder. For clarity, the “sequence” of an antibody includes the amino acid sequence of the antibody and the corresponding nucleic acid sequences. Adimab acknowledges and agrees that upon receipt of Program Antibodies, Leap may conduct testing on such Program Antibodies to optimize such Program Antibodies (and, to avoid doubt, the optimized versions thus created shall be Program-Benefited Antibodies).

Adimab retains title to the Adimab Materials, including all quantities of Program Antibodies that it provides under a Research Program, including during the Evaluation Term. Such quantities of Program Antibodies are (i) for use solely in assessing whether to exercise the Option for the applicable Target, and (ii) shall not be used in humans or for any commercial purpose. Should Leap not exercise its Option as described in Section 3.2(a) (Option), Leap shall return to Adimab or destroy any Program-Benefitted Antibodies in its possession on expiration of the Evaluation Term for such Target. Without limiting the generality of the foregoing, during the Evaluation Term and after expiration of the Options, if unexercised, Leap shall not provide Program-Benefitted Antibodies to Third Parties. Notwithstanding the foregoing, should Leap

exercise the Option for a given Target, all right, title and interest in and to those Program-Benefitted Antibodies shall belong to and vest in Leap (subject to the terms and conditions of this Agreement with respect to Program-Benefited Antibodies, including Section 9.3 (Commitments Regarding Program-Benefited Antibodies) hereof).

2.5Use of Leap Materials. Adimab shall use the Leap Materials solely to perform the Research Program for the applicable Target. Adimab shall not transfer or otherwise provide the Leap Materials to any Third Party. Adimab shall not use Leap Materials for any other purposes. For clarity, this means that, except as specified pursuant to the foregoing sentence, Leap retains title to the Leap Materials that it provides under a Research Program. [***] after the Research Term for such Target ends, Adimab will return to Leap or destroy any remaining Leap Materials (at Leap’s direction).

2.6Certain Restrictions on the Use of Antibodies.

(a)Adimab Restrictions. Adimab shall not provide any Third Party with any Program Antibody delivered to Leap. Adimab shall not deliver to Leap as a Program Antibody any antibody previously delivered to a Third Party.

To avoid doubt and notwithstanding anything to the contrary in this Agreement:

(i)nothing herein shall prevent Adimab from licensing or transferring some or all of the Adimab Platform Technology and/or Adimab Platform Technology Improvements to a Third Party (including technical support in connection therewith) nor shall anything herein require Adimab to in any way limit the use of the Adimab Platform Technology and/or Adimab Platform Technology Improvements by Adimab or a Third Party; and

Other than repeating information in any mutually agreed press release, neither Party will generate or allow any further

publicity regarding this Agreement or the transaction or research contemplated hereunder in which the other Party is identified, without giving the other Party the opportunity to review and comment on the press release. The Parties recognize the importance of announcing Option and the achievement of Milestones, and that Adimab is entitled to disclose these occurrences. Accordingly, the Parties hereby agree that each such event shall be publicly announced by the Parties if requested by ▇▇▇▇▇▇, and the Parties shall mutually agree upon the text of a press release to announce each such event. Leap shall not unreasonably withhold its consent to the manner in which Adimab proposes to make such disclosure. It is understood and agreed that Adimab sometimes issues press releases that group multiple achievements of the company, and that if Adimab chooses to group the initially approved text or the announcement of Option exercise and/or a milestone achievement under this Agreement with other accomplishments or events not relating to this Agreement, then the only portion of the press release into which the Leap shall have a consent right (such consent not to be unreasonably withheld), shall be those portions that relate to this Agreement.

6.7Certain Data. Notwithstanding this Article 6 (Confidentiality; Publicity), without disclosing Leap’s identity or the identity of the Target (although the class of protein of the Target may be disclosed), or the sequence of any Program Antibody, in order to describe the general capabilities and performance of the Adimab platform, Adimab shall be entitled to disclose generally Program Antibody attributes and Program Know-How, including the following: (a) Program Antibody binding affinities (kD), (b) expression range regarding Program Antibodies, and (c) germline distribution of Program Antibodies.
