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 Leap, 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

10

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 Leap 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

11

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

12

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

Each Party may disclose the other Party’s Confidential Information to the receiving Party’s officers, directors, employees, Affiliates, agents, representatives and contractors requiring access thereto for the purposes of this Agreement, provided, however, that prior to making any such disclosures, each such person shall be bound by terms at least as restrictive as those hereof to maintain Confidential Information in confidence and not to use such information for any purpose other than in accordance with the terms and conditions of this Agreement. Each Party agrees to take all steps necessary to ensure that the other Party’s Confidential Information shall be maintained in confidence including such steps as it takes to prevent the disclosure of its own proprietary and confidential information of like character. Each Party agrees that this Agreement shall be binding upon its officers, directors, employees, Affiliates, agents, representatives and contractors involved in the Research Program. Each Party shall take all steps necessary to ensure that its officers, directors, employees, Affiliates, agents, representatives and contractors shall comply with the terms and conditions of this Agreement. The foregoing obligations of confidentiality and non-use shall survive, and remain in effect for a period of [***] from, the termination or expiration of this Agreement in accordance with Article 9 (Term).

6.2Exclusions from Nondisclosure Obligation. The nondisclosure and nonuse obligations in Section 6.1 (General Confidentiality Obligations) shall not apply to any Confidential Information to the extent that the receiving Party can establish by competent written proof that it:

(a)at the time of disclosure is publicly known;

(b)after disclosure, becomes publicly known by publication or otherwise, except by breach of this Agreement by such Party;

23

(c)was in such Party’s possession at the time of the earlier of disclosure hereunder and disclosure under the agreement referred to in Section 6.1 (General Confidentiality Obligations);

(d)is received by such Party from a Third Party who has the lawful right to disclose the Confidential Information and who shall not have obtained the Confidential Information either directly or indirectly from the disclosing Party; or

(e)is independently developed by such Party (i.e., without reference to Confidential Information of the disclosing Party).

6.3Required Disclosures. If either Party is required, pursuant to a governmental law, regulation or order, to disclose any Confidential Information of the other Party, the receiving Party (i) shall give advance written notice to the disclosing Party, (ii) shall make a reasonable effort to assist the other Party to obtain a protective order requiring that the Confidential Information so disclosed be used only for the purposes for which the law or regulation required and (iii) shall use and disclose the Confidential Information solely to the extent required by the law or regulation.

6.4Terms of Agreement. The terms of this Agreement are the Confidential Information of both Parties. However, each Party shall be entitled to disclose the terms of this Agreement under legally binding obligations of confidence and limited use to: legal, financial and investment banking advisors; and potential and actual investors, acquirers and licensees or sublicensees doing diligence and counsel for the foregoing. In addition, if legally required, a copy of this Agreement may be filed by either Party with the SEC (or relevant ex-U.S. counterpart). In that case, the filing Party will if requested by the other Party diligently seek confidential treatment for terms of this Agreement for which confidential treatment is reasonably available, and shall provide the non-filing Party reasonable advance notice of the terms proposed for redactions and a reasonable opportunity to request that the filing Party make additional redactions to the extent confidential treatment is reasonably available under the law. The filing Party shall seek and diligently pursue such confidential treatment requested by the non-filing Party.

6.5Return of Confidential Information. Promptly after the termination or expiration of this Agreement for any reason, each Party shall return to the other Party all tangible manifestations of such other Party’s Confidential Information at that time in the possession of the receiving Party.

6.6Publicity. Either Party may make an initial press release announcing the execution of this Agreement, but such Party shall provide the text of such planned disclosure to the other Party sufficiently in advance of the scheduled disclosure to afford such other Party reasonable opportunity to review and comment upon the proposed text and the timing of such disclosure, and shall consider all reasonable comments of the other Party regarding such disclosure; provided, however, that no Party shall use the trademark or logo of the other Party, its Affiliates or their respective employee(s) in any publicity, promotion, news release or public disclosure relating to this Agreement or its subject matter, except as may be required by Law or required by the rules of an applicable US national securities exchange or except with the prior express written permission of such other Party, such permission not be unreasonably withheld. Other than repeating information in any mutually agreed press release, neither Party will generate or allow any further

24

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 Adimab, 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.

MISCELLANEOUS

10.1Independent Contractors. The Parties shall perform their obligations under this Agreement as independent contractors. Nothing contained in this Agreement shall be construed to be inconsistent with such relationship or status. This Agreement and the Parties’ relationship in connection with it shall not constitute, create or in any way be interpreted as a joint venture, fiduciary relationship, partnership or agency of any kind.

10.2Dispute Resolution.

(a)Initial Dispute Resolution. Either Party may refer any dispute in connection with this Agreement (“Dispute”) not resolved by discussion of the BD/Contract Liaisons to senior executives of the Parties (for Adimab, its CEO or his designee and for Leap, its CEO or his designee) for good-faith discussions over a period of [***] (the “Senior Executives Discussions”). Each Party will make its executives reasonably available for such discussions.

(b)Disputes Not Resolved Between the Parties.

For clarity, each Party hereby acknowledges that both the fact of and nature of a dispute is the Confidential Information of both Parties, and any disclosure of the fact of or the nature of such a dispute would be highly damaging to the non-disclosing Party.

[***] after a Party demands arbitration, each Party shall select one person to act as arbitrator, and the two Party-selected arbitrators shall select a third arbitrator [***] after their own appointment. If the arbitrators selected by the Parties are unable or fail to agree upon the third arbitrator, then the third arbitrator shall be appointed by the AAA. The place of arbitration shall be New York, NY. All proceedings and communications as part of the arbitration shall be in English. Following selection of the third arbitrator, the arbitrators shall complete the arbitration proceedings and render an award [***] after the last arbitrator is appointed.

(iii)Each Party shall bear its own costs and expenses and attorneys’ fees and an equal share of the arbitrators’ fees and any administrative fees or arbitration, unless in each case the arbitrators agree otherwise, which they are hereby empowered, authorized and instructed to do if they determine that to be fair and appropriate.

(iv)Except to the extent necessary to confirm an award or as may be required by law, regulation, or the requirement of any exchange on which a Party’s shares are traded, neither Party shall disclose the existence, content or results of an arbitration under this Agreement without the prior written consent of the other Party.
