article 2
PROGRAM.

2.1Research Programs.

(a)Target Selection. Surface shall nominate the first Target by providing notice of such Target to Adimab before the Effective Date. At any time prior to the expiration of the Discovery Term, Surface may initiate Research Programs with respect to additional Targets by notifying Adimab. In each case, such notice shall be in writing on a Target-by-Target basis, and shall be in the form of a completed Target Questionnaire with respect to each such Target and delivery of Surface’s antigen for such Target. Adimab’s obligation to perform such additional Research Programs shall be subject to the availability of Adimab researchers. Upon receipt of such notice by Adimab and Adimab’s confirmation of availability, the Parties shall work together to prepare the content of a Research Plan with respect to such Target, including the relevant Deliverables and success criteria. 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.

(b)Conduct of Research. Each Party shall use its commercially reasonable efforts to perform the Research Program 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 Surface providing the Surface Materials, if any, set forth in the applicable Research Plan. Such Surface Materials are expected to include Target antigen. Adimab’s obligations with regard to the performance of a particular Research Program shall expire at the end of the applicable Research Term. Adimab shall have the right to use Third Parties in the performance of its obligations hereunder, subject to Surface’s prior written consent if such Third Party is not identified and the applicable work not described in the Research Plan (any such permitted Third Party, a “Controlled Contractor”).

2.2Project Management.

(a)Scientific Research Committee. Promptly after the completion of the first Research Plan, the Parties shall form a steering committee consisting of [***] representatives from each Party with respect to the relevant Research Program (the “Research Committee”) to oversee the Research Programs. 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 to circulate, finalize and agree on minutes of each meeting within [***] days 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 consensus but solely within the limits specified in this Section 2.2, 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, 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 within [***] days after signing 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.

(d)Exclusive Use of Campaign Manager. During the applicable Research Term and for a period of [***] year after, the person whom Adimab has designated as the “Campaign Manager” for a given Research Program shall not perform, or supervise the performance of, research relating to the same Target using Adimab Platform Technology for Adimab or its Affiliates (whether for their own account or on behalf of any Third Party). It is understood and agreed that if such a person is no longer in Adimab’s or its Affiliate’s employ, then such person’s activities for another employer

are beyond the scope of (and are not Adimab’s responsibility to prevent under) the foregoing sentence.

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 Surface 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 Surface. Adimab shall maintain records, in sufficient details and in good scientific 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, by or on behalf of Adimab or any of its Affiliates or Controlled Contractors. All such records shall be kept in sufficient detail to identify and report those research activities conducted by Adimab, and shall be made available for inspection or copies provided to Surface upon Surface’s request. In the event that such records and data include disclosure of Adimab Platform Technology or Adimab Platform Technology Improvements, Adimab may redact those portions as is necessary to protect Adimab Platform Technology or Adimab Platform Technology Improvements prior to any review or inspection by or delivery to Surface.

(b)By Surface. During the applicable Research Term, at the junctures set forth in the applicable Research Plan, for so long as Surface or any of its Affiliates, licensees or sublicensees continue to generate or test any Program-Benefited Antibodies, Surface shall provide written reports to Adimab which provide any data Surface is required to provide under the applicable Research Plan and shall disclose information regarding the existence and progress of all Program-Benefited Antibodies since the date of the last report. For clarity, the information reported by Surface after the Research Term shall be solely for the purpose of allowing Adimab to monitor Surface’s obligations under this Agreement.

2.4Use of Adimab Materials. With respect to each Target, Surface and its Affiliates 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) and Section 3.2(b) of this Agreement while such licenses are in effect, including for Permitted Comparisons, or (c) to generate and test Program-Benefited Antibodies in accordance with Section 9.4. Surface and its Affiliates shall not use Adimab Materials for any other purposes. Without limiting the foregoing, Adimab acknowledges and agrees that upon receipt of Program Antibodies, Surface 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. During the Evaluation Term, such quantities of Program Antibodies are (i) for use solely in assessing whether to exercise the Commercial Option or Research Option for the applicable Target and for Permitted Comparisons, and (ii) shall not be used in humans or for any commercial purpose. Should Surface exercise neither its Research Option pursuant to Section 3.2(a) nor its Commercial Option pursuant to Section 3.3(a), Surface shall return to Adimab or destroy any Program-Benefitted Antibodies in its possession on expiration of the Evaluation Term for such Target. Surface shall destroy any

Licensed Research Antibodies in its possession on expiration of the relevant Research License Term. Without limiting the generality of the foregoing, during the Evaluation Term and after expiration of the Options, if unexercised, Surface shall not provide Program-Benefitted Antibodies to Third Parties, except as permitted by this Agreement.

2.5Use of Surface Materials. Adimab shall use the Surface Materials solely to perform the Research Program for the applicable Target. Adimab shall not transfer the Surface Materials outside of Adimab nor, for clarity, provide the Surface Materials to any Third Party. Within [***] days after the Research Term for such Target ends, Adimab will return to Surface or destroy any remaining Surface Materials (at Surface’s direction).

2.6Certain Restrictions on the Use of Antibodies.

(a)Adimab Restrictions. For each Target, until the earlier of expiration of the Evaluation Term for such Target or Surface’s exercise of its Commercial Option for such Target, Adimab shall not provide any of the Program Antibodies (or any of their Binding Sequence Information) to any Third Party in connection with performing a funded or sponsored research program for such Third Party. In addition, even if Surface does not exercise its Commercial Option for a particular Target, Adimab shall not file Program Antibody Patents for such Target or any patent application Covering any Program Antibody, unless independently rediscovered as contemplated below. For purposes of this Section 2.6, the performance of a program by Adimab means use of any of the Adimab Platform Technology to discover or optimize antibodies to the applicable Target based on activity against or with respect to such Target. Further, at all times, unless independently rediscovered without the use of (i) Surface Materials, (ii) Confidential Information of Surface (subject to Section 6.2(e)), (iii) any antibody library that is (A) [***] and (B) [***] (any such antibody library satisfying clauses (A) and (B)(1), a “Naive Antibody Library”) or (2) created specifically for use in the Research Program and [***] from a Naive Antibody Library in a Research Program (any such antibody library satisfying clauses (A) and (B)(2) an “Optimization Antibody Library”) and or any antibodies identified therefrom (including Program Antibodies), or any of their partial or whole sequences, or (iv) any Program Inventions to the extent solely owned by Surface based on the terms of this Agreement (subject to Section 6.2(e)), Adimab and its Affiliates shall not (I) provide the Program Antibodies or their Binding Sequence Information to any Third Party at any time, or any other antibody or their Binding Sequence Information identified from any Naive Antibody Library or Optimization Antibody Library under a Research Program or (II) use the Program Antibodies, any other antibody identified from any Naive Antibody Library or Optimization Antibody Library under a Research Program, or any of their Binding Sequence Information, to research, develop, manufacture or commercialize any biologic or drug products in for Adimab, its Affiliates or any Third Parties. Further, Adimab shall not perform any research, discovery or development with respect to a Target using any Naive Antibody Library or Optimization Antibody Library for which research, discovery or development was pursued with respect to such Target under a Research Program, and Adimab shall not provide (by any means, such as sale, license or transfer), any Naive Antibody Library or Optimization Antibody Library (or any substantial portion thereof) to any others.

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 a Third Party, subject to the restrictions above regarding any Naive Antibody Library or Optimization Antibody Library and antibodies identified therefrom (including Program Antibodies), or any of their Binding Sequence Information; and

(ii)nothing herein shall require Adimab to physically remove from its libraries, or to prevent from being included in future libraries, any Program-Benefited Antibodies, but Adimab is limited with respect to the use of any Naive Antibody Library and Optimization Antibody Library as provided above. This Agreement expressly provides for a reserved right for Adimab, its Affiliates, and those deriving rights from them (a) to include Program-Benefited Antibodies in antibody library(ies) (other than Naive Libraries) transferred or licensed by Adimab to Third Parties (including the transfer of physical possession of samples of Program-Benefited Antibodies to a Third Party as part of such transactions) and (b) to conduct any activity with respect to Program-Benefited Antibodies that are not Licensed Antibodies under this Agreement if Adimab (or such other party) arrives at such Program-Benefited Antibodies in a manner fully compliant with Adimab’s other covenants and obligations in this Agreement.

(iii)Adimab may independently regenerate Binding Sequence Information for any Program Antibodies without use or reference to any Program Inventions or any Naive Antibody Library or Optimization Antibody Library, other than Adimab Platform Technology Improvements (which nothing in this Agreement shall be read to restrict Adimab from using). In the case of independent rediscovery as provided above, Adimab shall be unrestricted in its use of and ability to provide the applicable independently rediscovered or independently regenerated antibodies to others.

(b)Surface Restrictions. Surface hereby covenants that it and its Affiliates shall not seek to or actually clinically develop or commercialize any Program-Benefited Antibody, or product containing either of the foregoing (other than the activities permitted hereunder during the Research Term and the Evaluation Term for the purpose of determining whether or not to exercise an Option for such Target), without first executing the Commercial Option with Adimab with respect to the applicable Target.

2.7Amendment and Restatement. The Parties hereby agree and acknowledge that this Agreement amends and restates the Original Agreement in its entirety and the Original Agreement is replaced with, and superseded by, this Agreement; provided, however, that, for the avoidance of doubt, any activities conducted under the Original Agreement shall be deemed to have been conducted under this Agreement.

During the Research Term and Evaluation Term for each Target, Surface hereby grants to Adimab a non-exclusive, nontransferable (except in connection with a permitted assignment of this Agreement) license (without the right to grant sublicenses except to Controlled Contractors) with respect to such Target under all Patents and Know-How Controlled by Surface (or its Affiliates) which Cover or relate to the Targets (including any that so relate by claiming antibodies directed to the Targets or a mechanism of action via the Targets) or any Surface Materials, solely to perform Adimab’s responsibilities as provided for in the applicable Research Plan.

3.2Research Rights.

(a)Research Option. On a Target-by-Target basis, Adimab hereby grants to Surface the exclusive option (for each Target, a "Research Option") to obtain the licenses set forth in Section 3.2(b) for Licensed Research Antibodies to the Target, exercisable by written notice to Adimab and (i) payment by Surface to Adimab of [***] on or before the date that is [***] months after the date on which Technical Milestone 1 is achieved for the Target, or (ii) payment of Technical Milestone 2 with respect to the Target and on or before the expiry of the Evaluation Term. Surface shall, in its written notice to exercise the Research Option for a Target, specify up to ten (10) Program Antibodies against the Target as the “Licensed Research Antibodies”. Upon such Research Option exercise, Adimab will provide to Surface sufficient materials to allow Surface to express any such Licensed Research Antibodies.

(b)Research License. Adimab hereby, effective on Surface's exercise of the Research Option for a Target and the applicable Licensed Research Antibodies:

(i)grants to Surface a worldwide, fully paid-up, sublicenseable through multiple tiers (solely as provided in Section 3.2(b)(ii)) license, under (A) the Adimab Platform Patents and, (B) any Licensed Program Antibody Patents, and (C) Know-How and other Patents Covering the Adimab Platform Technology, Adimab Platform Technology Improvements or Program Inventions, in each case, Controlled by Adimab (or its Affiliates) as of the start of and during the applicable Research License Term, to make, have made, import, have imported, export and have exported, in each case, for research purposes only, the Licensed Research Antibodies for such Target for a period beginning on the date of Surface’s exercise of the Research Option for such Target and expiring on the date [***] years after such exercise (subject to Section 9.1) (the “Research License Term”). Such license shall be non-exclusive and shall exclude the use of any Licensed Research

Antibodies in humans. This license grant is granted by Adimab as of the Effective Date as a current license grant, subject only to the Research Option exercise by Surface but not any other action by Adimab.

(ii)The license granted under Section 3.2(b)(i) shall be sublicensable solely to (x) Controlled Contractors or (y) in connection with the sublicensing of commercial rights to a therapeutic product against the same Target, in either case, pursuant to sublicenses that are consistent with all relevant terms and conditions of this Agreement, including Sections 2.4 and 9.4 hereof. Surface shall remain responsible for all payments and other performance obligations due under this Agreement, notwithstanding any license or sublicense that it may grant.

3.3Commercial Rights.

(a)Commercial Option. On a Target-by-Target basis, Adimab hereby grants to Surface the exclusive option (for each Target, a “Commercial Option”) to obtain the licenses of Section 3.3(b) for Licensed Antibodies to the Target, exercisable by payment of the Commercial Option Fee with respect to such Target to Adimab on or before the expiry of the Evaluation Term. Surface shall, in its written notice to exercise the Commercial Option for a Target, specify up to twenty (20) Program-Benefited Antibodies against the Target as the “Licensed Antibodies.” Additionally, Surface shall have the exclusive option to obtain licenses for up to five (5) additional Licensed Antibodies (“Additional Licensed Antibodies”), up to a total of twenty-five (25) Licensed Antibodies, with each Additional Licensed Antibody beyond the initial twenty (20) increasing the Commercial Option Fee in accordance with Section 4.3. For clarity, Additional Licensed Antibodies shall be classified as “Licensed Antibodies” under this Agreement. Upon such Commercial Option exercise, Adimab will provide to Surface sufficient materials to allow Surface to express any such Licensed Antibodies that were generated in the Research Program. Notwithstanding the foregoing, Surface may elect to partially exercise the Commercial Option by paying sixty five percent (65%) of the Commercial

Option Fee and designating up to ten (10) Program-Benefited Antibodies as Licensed Antibodies; provided, however, that prior to the expiration of the Evaluation Term, Surface shall either (i) pay the remaining thirty five percent (35%) of the Commercial Option Fee and, at any time prior to the expiration of the Evaluation Term (even if after payment of the remaining thirty five percent (35%) of the Commercial Option Fee) designate additional Program-Benefited Antibodies as Licensed Antibodies such that the total number of Licensed Antibodies does not exceed twenty (20) or (ii) fail to pay the remaining thirty five percent (35%) of the Commercial Option Fee, in which case the Commercial Option shall be deemed not to have been exercised with respect to such Target and no Program-Benefited Antibodies against such shall be deemed Licensed Antibodies from that point forward.

(b)Development and Commercialization License and Assignment. Adimab hereby, effective on Surface’s exercise of the Commercial Option for a Target and the applicable Licensed Antibodies:

(i)assigns to Surface, subject to the terms and conditions of this Agreement and without any further action required of either Party, all right, title and interest in and to those Licensed Program Antibody Patents that solely Cover those Licensed Antibodies, and at Surface’s request, Adimab

will execute title transfer and recordation assignments for any such Licensed Program Antibody Patents; and

(ii)grants to Surface a worldwide, royalty-bearing, sublicenseable through multiple tiers (solely as provided in Section 3.3(b)(iii)) license, under (A) the Adimab Platform Patents, (B) those Licensed Program Antibody Patents which are not assigned to Surface pursuant to Section 3.3(b)(i) (for any reason, including bankruptcy and other like proceedings described in Section 9.7), and (C) Know-How Covering the Adimab Platform Technology, Adimab Platform Technology Improvements or Program Inventions, in each case, Controlled by Adimab (or its Affiliates) as of the start of and during the term of this Agreement, in the Field, to research, have researched, develop, have developed, commercialize, have commercialized, make, have made, use, have used, sell, have sold, offer to sell, have offered to sell, import, have imported, export and have exported the Licensed Antibodies and Licensed Products for such Target during the term of this Agreement (subject to Section 9.1). Such license shall be non-exclusive under the Adimab Platform Patents and Know-How, and exclusive (even as to Adimab and its Affiliates) under the Licensed Program Antibody Patents. This license grant is granted by Adimab as of the Effective Date as a current license grant, subject only to the Commercial Option exercise by Surface but not any other action by Adimab.

(iii)The license granted under Section 3.3(b)(ii) shall be sublicensable solely pursuant to sublicenses that are consistent with all relevant terms and conditions of this Agreement, including Section 9.4 hereof. Surface shall remain responsible for all payments and other performance obligations due under this Agreement, notwithstanding any license or sublicense that it may grant.

3.4Diligent Development and Commercialization. Surface shall, if it exercises the Commercial Option with respect to a Target, devote Commercially Reasonable Efforts to preclinically and clinically develop, seek Marketing Approval for in the Major Markets, and launch and actively commercialize in the Major Markets at least one (1) Licensed Antibody against such Target. Annually, Surface will provide Adimab with a written report of Licensed Product progress in development and commercialization, by Surface’s and its Affiliates’ activities in that regard. If requested by Adimab, Surface shall meet with Adimab to discuss such report once annually.

3.5No Implied Licenses. Other than the licenses, options and assignments explicitly set forth in this Agreement, neither Party grants any intellectual property licenses, options or assignments to the other Party under this Agreement. This Agreement does not create any implied licenses.

article 4
FINANCIAL TERMS.

4.1Research Stage Fees.

(a)Research Funding. For each Research Program, Surface shall pay Adimab (i) an amount equal to [***] percent [***] of the estimated FTEs (at the FTE Rate) for the Research Program, such amount to be paid within [***] business days of agreement on a Research Plan, and (ii) within [***] business days of completion of a Research Program, an amount equal to [***] percent [***] of the actual FTEs expended by Adimab on the Research Program (at the FTE Rate) less the amount previous paid with respect to such Research Program pursuant to clause (i); provided,

however, that (1) such actual FTEs do not exceed the FTEs set forth in the applicable Research Plan (as amended from time to time) for such Research Program by more than [***] percent [***] and (2) Adimab has provided Surface with an invoice for each of such payments. Upon Surface’s reasonable request, Adimab shall provide customary and reasonable documentation to evidence that all such amounts so paid by Surface were used on FTE’s for the applicable Research Program.

(b)Technical Milestones. Surface shall pay Adimab two technical milestone fees with respect to each Research Program on each Target, as follows:

(i)The first technical milestone fee shall be equal to [***] for each Research Program, and such fee will be paid to Adimab by Surface within [***] business days of the later of (1) [***] and (2) provision by Adimab of an invoice for such payment to Surface; and

(ii)The second technical milestone fee shall be equal to [***] for each Research Program, and such fee will be paid to Adimab by Surface within [***] business days of the later of (1) [***] and (2) provision by Adimab of an invoice for such payment to Surface. In the event that the second technical milestone is met in the initial delivery, or in the event that the second technical milestone is met without payment of the first technical milestone, then, in either case, Surface shall pay both technical milestones.

4.2Research License Maintenance Fee. For each Research Option that is exercised by Surface, Surface shall pay an annual maintenance fee of [***] on each of the [***] anniversaries of the date of exercise of the relevant Research Option, subject to early termination as provided in this Agreement.

4.3Commercial Option Fee. In order to exercise the Commercial Option under Section 3.3(a) for a Target, Surface shall pay to Adimab a non-creditable, nonrefundable option exercise fee of [***] for each such Target (each, a “Commercial Option Fee”). If Surface elects to license Additional Licensed Antibodies, each Additional Licensed Antibody will increase the Commercial Option Fee by [***] up to a maximum Commercial Option Fee of [***] for each such Target.

4.4Milestone Payments. Subject to Section 4.7, for each Target, Surface shall report in writing to Adimab the achievement of each event (each, a “Milestone Event”) and pay the corresponding development milestone payment (each, a “Milestone Payment”) to Adimab, each within [***] days after the achievement of the corresponding milestone event in the following table (whether achieved by or on behalf of Surface or its Affiliates or any other entity acting on behalf of any of them or having received a license, sublicense or other rights from any of the foregoing with respect to a Licensed Product):

Milestone Event for each Licensed Product for a Target |  | Milestone Payment
[***] |  | [***]
[***] |  | [***]
[***] |  | [***]
[***] |  | [***]
[***] |  | [***]

Milestones Payments are payable one time only per Licensed Product, the first time each is achieved for such Licensed Product. If a subsequent Milestones Event is achieved for any Licensed

Product without a prior Milestone Event having been achieved for that Licensed Product, then Surface shall pay the Milestone Payment for such previous Milestone Event along with the payment for the most recently achieved Milestone Event. Notwithstanding the foregoing, if a Milestone Payment has been paid by Surface with respect to a Product that is then abandoned prior to the receipt of Marketing Approval by Surface, and Surface subsequently elects to research, develop and commercialize a back-up Product against the same Target, then no Milestone Payment shall be due for such previously paid Milestone Payment with respect to such back-up Product.

4.5Deferred Payment Option. The Commercial Option Fee and the Milestone Payments with respect to the first two Milestone Events set forth in Section 4.4 (i.e., those related to (a) [***] and (b) [***]) shall be deemed met and accrue when the Commercial Option is exercised or the applicable Milestone Event is achieved for a given Licensed Product, respectively and as the case may be. Surface may pay the Commercial Option Fee or the corresponding Milestone Payment, or Surface may provide written notice prior to the due date for such Commercial Option Fee or Milestone Payment of its election to delay payment of such amount until the earlier of (i) [***] (ii) [***] (iii) [***]. If Surface opts to delay any such payment, Surface shall pay Adimab, on the first business day of every calendar year, interest (each, an “Interest Payment”) accrued on all such deferred amounts at a rate of [***] per [***] (calculated on a daily basis), from the date any such Commercial Option Fee and/or Milestone Payments are due hereunder until such Commercial Option Fee and/or Milestone Payments, and any interest thereon, are paid in full; provided, however, that if Surface ceases all research and development activities with respect to Program-Benefited Antibodies against the same Target for which a payment is delayed, then Surface shall not be obligated to make such Interest Payment and the applicable Commercial Option Fee and Milestone Payments, all of which are hereby forgiven in such circumstances; and provided, further, however, that in the event that Surface (or its Affiliate or licensee) subsequently resumes research or development on Program-Benefited Antibodies against such Target, Surface shall immediately pay to Adimab any unpaid Interest Payments (including any interest which has accrued on such Interest Payments during the period since Surface last made an Interest Payment to Adimab with respect to such Program-Benefited Antibody), and Surface shall resume the payment of Interest Payments on the first business day of the next calendar year.

4.6Royalties.

(a)Royalty Payments. Subject to Section 4.7, as to each Licensed Product sold during the applicable Royalty Term in a country, on a Licensed Product-by-Licensed Product basis, Surface shall pay Adimab the following royalties, based on the royalty rate applicable to the relevant portion of annual worldwide Net Sales for such Licensed Product during the applicable Royalty Term for such Licensed Product in such country (“Royalty Payments”):

Portion of Worldwide Calendar Year Net Sales |  | Royalty Rate
[***] |  | [***]
[***] |  | [***]

(b)Other Royalty Provisions. Only one royalty will be due with respect to the same unit of Licensed Product, even if such Licensed Product unit is comprised of more than one Licensed Antibody or any modified or derivative forms thereof.

(c)Adjustment for Third Party IP. If Surface or any of its Affiliates enters into any Third Party Patent Licenses, then [***] of the net sales royalties actually paid to the Third Party under the Third Party Patent License with respect to Net Sales of any given Licensed Product in any given calendar quarter in any given country may be offset against the royalty that would otherwise have been payable to Adimab with respect to such same Net Sales; provided, however, that in no event shall the royalty owed to Adimab be reduced by more than [***] than the payment which would otherwise be due hereunder with any excess carried over to future royalty period(s) until such excess may be used in compliance with this proviso.

It is understood, agreed and acknowledged that Adimab’s allowing Surface to claim the credit of this Section 4.6 as to any particular Third Party Patent License: [***].

(d)Milestone Payments and Royalty Payments for Certain [***]. In the event that a single Licensed Product contains [***] Program Antibodies, [***], then (i) Surface shall owe only one Milestone Payment for the achievement of a given Milestone Event with respect to such Licensed Product, and (ii) Surface shall owe only one Royalty Payment with respect to any specific portion of Net Sales of such Licensed Product.

4.7Milestone Payments and Royalty Payments for Adimab Diagnostic Products for use with or in connection with External Products. Surface shall make the following payments with respect to Adimab Diagnostic Products for use with or in connection with External Products in lieu of the payments set forth in Sections 4.4 and 4.6(a).

[***] |  | [***]
[***] |  | [***]
[***] |  | [***]

For clarity, no payment is due under this Agreement (including under Section 4.4 or 4.6) with respect to (a) any Companion Diagnostic or Other Diagnostic Product (although payments shall be due under Sections 4.4 and 4.6(a) with respect to any applicable therapeutic Licensed Product(s)) or (b) any External Product. In addition, except as expressly provided in this Section 4.7, (i) milestone payments due for Adimab Diagnostic Products for use with or in connection with External Products are subject to the remaining terms and conditions of Section 4.4 (mutatis mutandis), and (ii) royalty payments due for Adimab Diagnostic Products for use with or in connection with External Products are subject to the remaining terms and conditions of Section 4.6 (mutatis mutandis).

4.8Quarterly Payment Timings. All royalties due under this Agreement shall be paid quarterly within [***] days after the end of the relevant calendar quarter for which royalties are due.

4.9Royalty Payment Reports. With respect to each calendar quarter, within [***] days after the end of the calendar quarter, Surface shall provide to Adimab a written report stating the number and description of all Licensed Products sold during the relevant calendar quarter; the gross sales associated with such sales; and the calculation of Net Sales on such sales. The report shall provide all such information on a country-by-country and Licensed Product-by-Licensed Product basis if reasonably available.

4.10Payment Method. All payments due under this Agreement to Adimab shall be made by bank wire transfer in immediately available funds to an account designated by Adimab. All payments hereunder shall be made in the legal currency of the United States of America, and all references to “$” or “dollars” shall refer to United States dollars (i.e., the legal currency of the United States).

4.11Taxes. The Parties agree to cooperate with one another and use reasonable efforts to minimize obligations for any and all income or other taxes required by applicable law to be withheld or deducted from any royalties, milestone payments or other payments made by Surface to Adimab under this Agreement, including by completing all procedural steps, and taking all reasonable measures, to ensure that any withholding tax is reduced or eliminated to the extent permitted under applicable law, including income tax treaty provisions and related procedures for claiming treaty relief. To the extent that Surface is required to deduct and withhold taxes on any payment to Adimab, Surface shall deduct and withhold such taxes and pay the amounts of such taxes to the proper government authority in a timely manner and promptly submit to Adimab an official tax certificate or other evidence of such withholding sufficient to enable Adimab to claim such payment of taxes. Surface shall provide Adimab with reasonable assistance in order to allow Adimab to recover, as permitted by applicable law, withholding taxes, value added taxes or similar obligations resulting from payments made hereunder or to obtain the benefit of any present or future treaty against double taxation which may apply to such payments. Adimab shall provide Surface with any tax forms that may be reasonably necessary in order for Surface to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral tax income treaty.

4.12Records; Inspection.

(a)Surface shall keep and ensure that its Affiliates keep complete and accurate records of its sales and other dispositions (including use in clinical trials, or provision on a compassionate use basis or as marketing samples) of Licensed Antibody and Licensed Product including all records that may be necessary for the purposes of calculating all payments due under this Agreement for a period of at least [***] years. Surface shall make such records available for inspection by an accounting firm selected by Adimab (and which is reasonably acceptable to Surface) at Surface’s premises in the United States on reasonable notice during regular business hours as provided in Section 4.11(b).

(b)At Adimab’s expense no more than [***] per calendar year, Adimab has the right to retain an independent certified public accountant from a nationally recognized (in the U.S.) accounting firm to perform on behalf of Adimab an audit, conducted in accordance with U.S. generally accepted accounting principles (GAAP), of such books and records of Surface and its Affiliates as are deemed necessary by the independent public accountant to report on Net Sales, for the period or periods requested by Adimab within the [***] most recent calendar years as of the date of the audit performance, and the correctness of any report or payments made under this Agreement. No period may be audited more than once. Prior to any review, such accounting firm shall have entered into a written agreement with Surface (or its Affiliates, licensees or sublicensees) limiting the use of such records to verification of the accuracy of payments due under this Agreement and prohibiting the disclosure of any information contained in such records to a Third Party and to Adimab for a purpose other than as set forth in this Section 4.11(b). The report of such accounting firm shall be limited to a certificate stating whether any report made or invoice or payment submitted by Surface

during such period is accurate or inaccurate and the actual amounts owed by or due under this Agreement to Adimab for such period.

(c)If the audit reveals an underpayment, Surface shall promptly pay to Adimab the amount of such underpayment plus interest in accordance with Section 4.15. Any overpayment made by Surface shall be fully creditable against amounts payable in subsequent payment periods or promptly refunded, at Adimab’s election. Any audit by an independent certified public accounting firm under this Section 4.11 is to be made at the expense of Adimab, but if the audit reveals that the monies owed by Surface to Adimab has been understated by more than [***] percent [***] for the period audited, Surface shall, in addition, pay the reasonable out-of-pocket costs incurred by Adimab of such audit.

(d)The Parties agree that all information provided in a royalty payment report, all records kept by Surface or its Affiliates, licensees and sublicensees under this Section 4.11 or Section 4.12, and any information provided by the independent certified public accounting firm to Adimab are Confidential Information of Surface.

4.13Licensee/Sublicensee Reports, Records and Audits. If Surface grants any Product licenses or sublicenses, the agreements for such licenses and sublicenses shall include an obligation for the licensee or sublicensee to (i) maintain records adequate to document and verify the proper payments (including milestones and royalties) to be paid to Adimab; (ii) provide reports with sufficient information to allow such verification; and (iii) allow Adimab (or Surface if requested by Adimab) to verify the payments due (such audit right is not required to be any stronger than that of Section 4.11).

4.14Foreign Exchange. If any currency conversion shall be required in connection with the calculation of amounts payable hereunder, such conversion shall be made using the exchange rates (a) used by Surface (or the selling entity) for its own financial reporting purposes in its worldwide accounting system (which shall be consistent with applicable accounting standards), if Surface (or the selling entity) is a public company, or (b) if Surface is not a public company, then shall be determined the same way except that the rates shall be the average of the purchase and sale rates for U.S. Dollars for such day as reported on the fifth (5th) business day prior the payment due date for the purchase and sale of U.S. dollars, as reported by the Wall Street Journal, Eastern Edition (or if it no longer exists, a similarly authoritative source). With any payment in relation to which a currency conversion is performed to calculate the amount of payment due, Surface shall provide to Adimab a true, accurate and complete copy of the exchange rates used in such calculation.

4.15Non-refundable, non-creditable payments. Each payment that is required under this Agreement is non-refundable and non-creditable.

4.16Late Payments. Any amount owed by Surface to Adimab under this Agreement that is not paid within the applicable time period set forth herein will accrue interest at the rate of [***] percent [***] above the then-applicable short-term three-month London Interbank Offered Rate (LIBOR) as quoted in the Wall Street Journal, Eastern Edition (or if it no longer exists, a similarly authoritative source) calculated on a daily basis, or, if lower, the highest rate permitted under applicable law.

article 5

Each assigning Party hereby appoints the other Party as attorney-in-fact solely to execute and deliver the foregoing documents and instruments if such other Party after making reasonable inquiry does not obtain them from the assigning Party. Each Party (and its Affiliates) shall perform its activities under this Agreement through personnel who have made a similar assignment and appointment to and of such Party or any of its Affiliate. Each assigning Party shall make its relevant personnel (and their assignments and signatures on such documents and instruments) reasonably available to the other Party for assistance in accordance with this Article at no charge.

(b)Joint Ownership Implementation. As regards Joint Serendipitous Inventions and the Program Patents to the extent claiming them, either Party is entitled to practice and license them without consent of and without a duty of accounting to the other Party in accordance with the co-ownership rights of co-inventors under U.S. law, subject to the terms of this Agreement. Each Party hereby grants all permissions, consents and waivers with respect to, and all licenses under, the Joint Serendipitous Inventions and the Program Patents claiming them as necessary to achieve throughout the world the nature of joint ownership rights of the foregoing as described in Section 5.1 and the foregoing sentence and otherwise subject to the terms of this Agreement. To avoid doubt, this Section 5.2(b) does not imply any permission, consent or waiver with respect to, or

license under, any Patent or item of Know-How other than the Joint Serendipitous Inventions and the Program Patents to the extent claiming them.

5.3Disclosure. During the term of the Agreement, each Party shall promptly disclose to the other Party [***] any Program Inventions that would be Covered by Program Antibody Patents or in Surface’s case that are Adimab Platform Technology Improvements (which, to avoid doubt, are assigned to Adimab under this Agreement). Such disclosure shall occur as soon as possible, but in any case within [***] days after the Party determines such Program Inventions have been invented. To avoid doubt, this Section 5.3 shall not be read to require Adimab to disclose Program Inventions constituting Adimab Platform Technology Improvements to Surface.

5.4Program Patent Prosecution.

(a)Adimab Platform Technology. Adimab shall have the sole right (but not the obligation) to Prosecute all Adimab Platform Patents, all at its own expense.

(b)Program Antibody Patents. Surface shall have the sole right (but not obligation except as provided below) to Prosecute all Program Antibody Patents, at Surface’s expense, and prior to Commercial Option exercise, in Adimab’s name, and after Commercial Option exercise, in Adimab’s name to the extent that any Licensed Program Antibody Patent is not assigned to Surface pursuant to Section 3.3(b)(i). Such right shall continue for the duration of the longer of the Evaluation Term and, if Surface exercises the Commercial Option, the term of the license under Section 3.3(b)(ii), subject to all of the following:

(i)Prior to Commercial Option exercise, [***].

(ii)Prior to Commercial Option exercise, [***].

(iii)Both prior to and after Commercial Option exercise, Adimab shall have the right to review and comment on prosecution of the Program Antibody Patents, and Surface shall reasonably consider but is not required to accept any such comments. Adimab shall grant Surface the necessary authority to Prosecute the Program Antibody Patents (including that Adimab shall join any suit or action regarding the foregoing at Surface’s request). Surface shall provide Adimab with copies of all correspondence with patent offices relating thereto (including office actions and the like) promptly after receipt and drafts of all filings and correspondence with such offices no less than [***] in advance of filing.

(iv)If Surface does not exercise the Commercial Option for a Target, then [***].

(v)If Surface does exercise the Commercial Option for a Target, then [***].

(vi)[***].

(vii)Surface shall use Commercially Reasonable Efforts to Prosecute at least one Licensed Program Antibody Patent in at least each country of the Major Markets.

(viii)Surface shall be solely responsible for all costs of the activities under this Section 5.4(b), except (A) as expressly provided under this Section 5.4(b) or (B) that to the extent Adimab hires

counsel to review and comment on Surface’s prosecution then Adimab shall be solely responsible for the fees to such counsel.

(ix)Except as provided in this Agreement, Adimab shall not disclose or claim (or have or license any others to disclose or claim) any Program Antibody (or the Binding Sequence Information thereof) or any other antibody or their Binding Sequence Information identified from any Naive Antibody Library or Optimization Antibody Library, unless independently invented in a manner in compliance with the terms of this Agreement (including the restrictions on Naive Antibody Libraries and Optimization Antibody Libraries contained herein). For clarity, (1) Adimab shall not nor allow any others to refile or Prosecute any Patent applications [***] and (2) the foregoing prohibitions shall not prevent Adimab from filing broad Patents (such as, for example, Patents which Cover an antibody library) which Cover a Program Antibody or its Binding Sequence Information so long as Adimab does recite in any claim the such Program Antibody or its Binding Sequence Information in such Patent, and so long as Adimab does not disclose such Program Antibody or its Binding Sequence Information in such Patent.

(c)Responsibility. It is understood and agreed that searching for, identification and evaluation of Third-Party Patents that may apply to any Program Antibodies based on sequence, Target or the like is the responsibility of Surface and Adimab shall have no responsibility for the foregoing nor liability if any such Third-Party Patents exist.

(d)Serendipitous Program Inventions.

(i)Adimab Program Inventions. As between the Parties, Adimab shall have the sole right, at its sole expense, to prepare, file, prosecute, enforce and maintain (including conducting or participating in interferences and oppositions and the like) (collectively “Prosecute”) all Patents directed to Adimab Program Inventions but not falling within the Program Antibody Patents or the Adimab Platform Technology Improvements (which, to avoid doubt, are both addressed above).

(ii)Surface Program Inventions. Surface shall be responsible, at its sole expense, to Prosecute all Program Patents directed to Surface Program Inventions but not falling within Program Antibody Patents or the Adimab Platform Technology Improvements (which, to avoid doubt, are both addressed above).

Neither Party shall disclose any Confidential Information of the other Party to any Third Party. Neither Party shall use the Confidential Information of the other Party for any purpose other than as required to perform its obligations or exercise its rights hereunder. Each Party may disclose the other Party’s Confidential Information to the receiving Party’s directors, employees, contractors and advisors 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 written agreement 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. Surface may disclose sequence data and other data generated under the Research Program to legal, financial and investment banking advisors, and potential and actual investors, lenders, financing sources, Change of Control counterparties, acquirers, collaborators, sublicensees and licensees and counsel for the foregoing, that are under legally binding obligations of confidence and limited use and to national patent offices in accordance with Section 5.4. 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 Affiliates, and upon the employees and contractors involved in the Research Program of such Party and its Affiliates. Each Party shall take all steps necessary to ensure that its Affiliates and employees 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 [***] years from, the termination or expiration of this Agreement in accordance with Article 9.

6.2Exclusions from Nondisclosure Obligation. The nondisclosure and nonuse obligations in Section 6.1 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;

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

(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 to disclose any Confidential Information of the other Party, pursuant to a governmental law, regulation or order, or an order of a court of competent jurisdiction or to defend or prosecute litigation or as part of an arbitration; provided, however, that the receiving Party (i) shall give advance written notice to the disclosing Party, (ii) shall make a reasonable effort to assist the disclosing 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 so required.

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, lenders, financing sources, Change of Control counterparties, acquirers, collaborators, sublicensees and licensees 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; provided, however, that the receiving Party shall be entitled to retain one (1) copy of such information solely for the purpose of monitoring such Party’s surviving obligations under this Agreement. Electronic copies of Confidential Information contained in backups or electronic archives made in the normal course of the receiving Party’s business shall not be required to be destroyed or returned in accordance with this Section 6.5.

6.6Publicity. Each of Adimab and Surface may publish a press release describing the collaboration, but without identifying the targets to be worked on or the economic terms of the collaboration. The Parties will agree on specific press release language promptly following the Effective Date. Other than repeating information in such press release (or any subsequent 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 Commercial Option exercise and the achievement of Milestones, and that Adimab is entitled to disclose these occurrences; provided, however, that Adimab may disclose the identity of Surface but will not disclose the identity of any of Surfaces’ licensees, sublicensees or collaborators (if applicable) or the identity of the Target or the possible indication(s) (although the class of protein of the Target (but not the family) may be disclosed). 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. Surface 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 Commercial 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 Surface 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, without disclosing Surface’s (or any of its Affiliates’ or licensees’, sublicensees’ or collaborators’) identity or the identity of the Target or the possible indication(s), or information making such identities or indications reasonably discernable (although the class of protein of the Target (but not the family) 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 , including the following: (a) Program Antibody binding affinities (K D), (b) expression range regarding Program Antibodies, and (c) germline distribution of Program Antibodies.

article 9
TERM.

9.1Term. The term of this Agreement shall commence on the Effective Date and shall expire upon the later of (a) the earlier of (i) the expiration of the Commercial Option(s) and Research Option(s) (if they expire without being exercised), and (ii) expiration of 12 months from the Effective Date without Surface providing Surface Materials that successfully pass Adimab’s QC; or (b) if at least one Research Option has been exercised but no Commercial Option has been exercised, upon the expiration of the last to expire Research License Term; or (c) on a country-by-country and Licensed Product-by-Licensed Product basis on the expiration of the last Royalty Term for a Licensed Product in the particular country, in each case, unless earlier terminated by a Party as set forth below in this Article 9. On expiration under (c) in a particular country, the license of Section 3.3(b)(ii) for the corresponding Licensed Product and its Licensed Antibody shall automatically convert to be perpetual, irrevocable, non-exclusive and fully-paid up in such country.

9.2Material Breach.

(a)Either Party may terminate this Agreement for the material breach of this Agreement by the other Party, if such breach remains uncured [***] days following notice from the non-breaching Party to the breaching Party specifying such breach.

(b)For Targets for which the Commercial Option or Research Option has been exercised, the foregoing Section 9.2(a) applies on a Target-by-Target basis to the extent that a breach relates to specific Targets, and such termination shall be applicable to only those Targets (and its associated Patents, Licensed Antibodies, Licensed Research Antibodies, and Licensed Products) to which the uncured the material breach relates.

(c)If there is a good faith dispute as to the existence or cure of a breach or default pursuant to Section 9.2(a), all applicable cure periods will be tolled during the existence of such good faith dispute and no termination for a breach which is disputed in good faith will become effective until such dispute is resolved pursuant to the process set forth in Section 10.2 and a [***] day cure period offered thereafter.

9.3Termination for Convenience. Surface may terminate this Agreement in its entirety on [***] prior written notice to Adimab. On a Target-by-Target basis, after Commercial Option or Research Option exercise, Surface may also terminate this Agreement as to all Licensed Antibodies, Licensed Research Antibodies and Licensed Products to a particular Target by [***] prior written notice to Adimab.

9.4Commitments Regarding Program-Benefited Antibodies. The Parties intend that if Surface, its licensees, or its sublicensees, or the Affiliate of any of the foregoing, will pursue any Program-Benefited Antibodies, they shall do so under this Agreement paying fees to Adimab as provided in Article 4. This Agreement gives Surface, its licensee, its sublicensee or the Affiliate of any of the foregoing the right to modify the Program Antibodies, by including modified versions of them and derivatives of them in the definition of “Licensed Antibodies” provided above. Surface, its licensee, its sublicensee or the Affiliate of any of the foregoing shall even be entitled to choose to pursue or use information obtained under this Agreement from Adimab to pursue an antibody not covered by the Program Antibody Patents, but only if Surface, its licensee, its sublicensee or the Affiliate of any of the foregoing treats the pursued antibody as milestone- and royalty-bearing under this Agreement to the extent such pursued antibody is a Program-Benefited Antibody. The Parties intend that Surface, its licensee, its sublicensee or the Affiliate of any of the foregoing shall not develop or commercialize a Program-Benefited Antibody, except in accordance with this Agreement (including exercising the Commercial Option and paying Adimab the Commercial Option Fee, Milestone Payments and royalties on the Program-Benefited Antibody product as (or as if) a Licensed Product under this Agreement). Accordingly, even if this Agreement expires or terminates (other than an expiration under Section 9.1 following a Commercial Option exercise after all Royalty Terms have expired for the applicable Program-Benefited Antibody or Licensed Product), Surface hereby covenants that Surface, its licensees and sublicensees and the Affiliates of any of the foregoing (a) shall not research, develop or commercialize any Program-Benefited Antibody or Licensed Product containing such an antibody except as a Licensed Product under this Agreement, and (b) shall not license or otherwise grant rights to any entity to do the foregoing.

9.5Survival in All Cases. Termination of this Agreement shall be without prejudice to or limitation on any other remedies available to nor any accrued obligations of either Party. In addition, Sections 2.3, 2.4, 2.5, 2.6, 3.5, 4.8 through 4.16 (with respect to payment obligations outstanding or having accrued as the effective date of termination or expiration), 5.1, 5.2, 5.4, 5.6, and 7.3, and Articles 1, 6, 8, 9 and 10 shall survive any expiration or termination of this Agreement. Further, upon termination of this Agreement by either Party under Section 9.2 or 9.3, Surface, its licensees and sublicensees, and their Affiliates will no longer develop or commercialize any Licensed Antibody or Licensed Product (subject to Section 9.2(b) for partial terminations).

9.6Survival of Sublicenses. In the event that the licenses granted to Surface under this Agreement are terminated, any granted sublicenses to Third Parties will remain, at any such Third Party’s election, in full force and effect; provided, that the sublicense agreement is consistent with the terms of this Agreement, the sublicensee is not then in breach of its sublicense agreement, and such Third Party agrees to be bound to Adimab as a licensor under the terms and conditions of this Agreement (including payment obligations as reflected in this Agreement with respect to Adimab). In such event, Adimab will negotiate and enter into an appropriate license agreement with such Third Party incorporating the terms and conditions of this Agreement.

9.7Bankruptcy. All licenses and rights to licenses granted under or pursuant to this Agreement by Adimab to Surface are, and will otherwise be deemed to be, for purposes of Section 365(n) of the United States Bankruptcy Code (the “Bankruptcy Code”), licenses of rights to “intellectual property” as defined under Section 101(35A) of the Bankruptcy Code. The Parties agree that Surface, as a licensee of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the Bankruptcy Code. The Parties further agree that that upon commencement of a bankruptcy proceeding by or against Adimab under the Bankruptcy Code, Surface will be entitled to a complete duplicate of, or complete access to (as Surface deems appropriate), all such intellectual property and all embodiments of such intellectual property. Such intellectual property and all embodiments of such intellectual property will be promptly delivered to Surface (a) upon any such commencement of a bankruptcy proceeding and upon written request by Surface, unless Adimab elects to continue to perform all of its obligations under this Agreement, or (b) if not delivered under (a) above, upon the rejection of this Agreement by or on behalf of Adimab and upon written request by the Surface. Adimab (in any capacity, including debtor-in-possession) and its successors and assigns (including any trustee) agrees not to interfere with the exercise by Surface or its Affiliates of its rights and licenses to such intellectual property and such embodiments of intellectual property in accordance with this Agreement, and agrees to assist Surface and its Affiliates in obtaining such intellectual property and such embodiments of intellectual property in the possession or control of Third Parties as reasonably necessary or desirable for Surface to exercise such rights and licenses in accordance with this Agreement. The foregoing provisions are without prejudice to any rights Surface may have arising under the Bankruptcy Code or other applicable law. Notwithstanding the foregoing in this Section 9.7, nothing in this Section 9.7 shall be read to entitle Surface to obtain disclosure of or access to Adimab Platform Technology (including Adimab Platform Technology Improvements), whether or not as an “embodiment,” “update,” or otherwise, at any time, and Surface shall not under any circumstances notwithstanding anything express or implied in this Agreement be entitled to disclosure of Adimab Platform Technology or Adimab Platform Technology Improvements.

9.8Return of Adimab Materials. Except as otherwise provided in Section 2.4, on a Target-by-Target basis, Surface shall either return to Adimab or destroy all Adimab Materials (other than Adimab Materials relating to Licensed Antibodies) upon expiration or termination of the Evaluation Term without any Commercial Option or Research Option being exercised, and all Adimab Materials on expiration (other than for any Licensed Product and the corresponding Licensed Antibody an expiration under Section 9.1 following a Commercial Option exercise and after all Royalty Terms for such Licensed Product have expired) or termination of this Agreement.

article 10
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 Surface, its CEO or his designee) for good-faith discussions over a period of not less than sixty (60) days (the “Senior Executives Discussions”). Each Party will make its executives reasonably available for such discussions.

(b)Disputes Not Resolved Between the Parties. If the Parties are unable to resolve the dispute through the Senior Executives Discussions within such sixty (60) days, then either Party may, as the sole and exclusive means for resolving disputes under this Agreement, proceed to demand confidential arbitration by written notice to the other Party and making a filing with the AAA in accordance with Section 10.2(c). 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.

(c)Arbitration.

(i)Any Dispute referred for arbitration shall be finally resolved by binding arbitration in accordance with the most applicable rules of the American Arbitration Association (“AAA”) and judgment on the arbitration award may be entered in any court having jurisdiction.

​

(ii)The arbitration shall be conducted by a panel of three (3) people experienced in the business of biopharmaceuticals. If the issues in dispute involve scientific, technical or commercial matters, then any arbitrator chosen under this Agreement shall have educational training and/or industry experience sufficient to demonstrate a reasonable level of relevant scientific, technical and commercial knowledge as applied to the pharmaceutical industry. If the issues in dispute involve patent matters, then at least one (1) of the arbitrators shall be a licensed patent attorney or otherwise

knowledgeable about patent law matters. Within [***] days 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 within [***] days 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 Boston, Massachusetts. 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 within [***] months 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.

(v)In no event shall an arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the subject matter of the Dispute would be barred by the applicable statute of limitations under New York law.

10.3Governing Law. This Agreement shall be governed by and interpreted in accordance with the laws of the Commonwealth of Massachusetts, excluding its conflicts of laws principles; provided, however, that matters of Patent law will be determined in accordance with the United States federal law. Any and all judicial resolutions of disputes in connection with this Agreement shall be in federal or state court located in Massachusetts, and each Party hereby consents to the jurisdiction and venue of such courts, and waives all defenses it may have to such jurisdiction and venue, including that the court cannot assert personal jurisdiction over the defendant and forum non conveniens.

​

10.4Entire Agreement. This Agreement (including its Exhibits) set forth all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties with respect to the subject matter hereof and supersedes and terminates all prior agreements and understandings between the Parties with respect to such subject matter (including that certain Mutual Confidentiality Agreement between the Parties dated March 27, 2014). No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by the respective authorized officers of the Parties.

10.5Assignment. Neither Party may assign in whole or in part this Agreement without the advance written consent of the other Party, except as set forth in the following sentence. Either Party may assign this Agreement in its entirety to the successor to all or substantially all of its stock or assets to which this Agreement relates in connection with its merger with, or the sale of all or substantially all of its stock or assets to which this Agreement relates to, another entity, regardless of the form of the transaction (including any Change of Control). In addition, Adimab may assign this

Agreement or any of its rights under this Agreement, in connection with the sale of, monetization of, transfer of, or obtaining financing on the basis of the payments due to Adimab under this Agreement or debt or project financing in connection with this Agreement. Also, Surface may assign its rights and obligations under this Agreement on a Target-by-Target basis, at any time after Commercial Option exercise for the particular Target, to any entity to which Surface assigns all or substantially all of its assets with respect to such Target (and its related Patents, Licensed Antibodies and Licensed Products); provided, however, [***]. Subject to the foregoing, this Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective successors and permitted assigns. Notwithstanding the foregoing, Adimab may not assign or otherwise transfer (by operation of law or otherwise) this Agreement if the assignee does not assume all of Adimab’s obligations under this Agreement or Adimab does not remain bound to perform all obligations that are not assigned to the assignee. Any assignment of this Agreement not made in accordance with this Agreement is prohibited hereunder and shall be null and void.

10.6Severability. If one or more of the provisions in this Agreement are deemed unenforceable by law, then such provision shall be deemed stricken from this Agreement and the remaining provisions shall continue in full force and effect.

10.7Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by a Force Majeure and the nonperforming Party promptly provides notice of the prevention to the other Party. Such excuse shall be continued so long as the condition constituting Force Majeure continues and the nonperforming Party takes reasonable efforts to remove the condition, but no longer than [***], whereupon the other Party may assert breach by the nonperforming Party.

10.8Notices. Any notice required or permitted to be given under this Agreement shall be in writing, shall specifically refer to this Agreement and shall be deemed to have been sufficiently given for all purposes if mailed by first class certified or registered mail, postage prepaid, delivered by express delivery service or personally delivered. Unless otherwise specified in writing, the mailing addresses of the Parties shall be as described below.

Partner Completed Target Questionnaire

Information you are able to provide about your target will help Adimab design a customized selection strategy and detailed work plan. This will ultimately allow Adimab to deliver antibodies that fit your desired properties.

Overview

The primary factors that determine the successful outcome of an IgG library screen are

| (i) | the quality of the antibody library

| (ii) | the quality and consistency of the antigens used in the selection process

While Adimab has taken extensive steps to ensure the quality of its libraries, the antigen used to interrogate our library is provided by the Partner and must be properly characterized to meet screening requirements. Adimab has compiled the following set of criteria to help ensure the quality of the antigen(s) used in the selection process which will ultimately lead to a successful campaign. Any additional information the Partner can provide relating to your antigen is valuable. When multiple forms of the antigen are available, and are used in the selection, it increases the potential success of the campaign. As an example, an RTK-ECD can be supplied as both an Fc-fusion protein and as a tagged monomeric protein, or produced and purified using preferred host expression systems and purification tags.

Target (sample answers provided below in blue)

| • |  | What is the nature of your target (e.g., extracellular domain of a membrane protein)?

| • |  | Serum enzyme

| • |  | Does your target protein have an affinity tag?

| • |  | If yes, what tag?

| • |  | C-terminus His-tag

| • |  | Are you aware of any post-translational modification to your target protein (e.g., N-glycosylation, O-glycosylation or phosphorylation)?

| • |  | None

Adimab Confidential - Sample Work Plan

| • |  | Is your target a chimeric protein (e.g., Fc-fusion protein)?

| • |  | No

| • |  | Does your target protein interact with other proteins or form complexes?

| • |  | Yes

| • |  | Does your target exist naturally as a monomer, dimer, trimer, etc.?

| • |  | Target is naturally monomeric

| • |  | Is your target available in multiple formats (e.g., monomeric, dimeric, multiple tags, etc.)?

| • |  | No

| • |  | How stable is your target protein (e.g., stability @ 4°C, freeze thaw cycle data)?

| • |  | Stable at +4°C for months

| • |  | Do you have access to 10 nmol quantities (e.g., ~1 mg of 75 kDa protein) of your target protein?

| • |  | Yes

| • |  | Do you have cell-based or other assays to determine the bioactivity of your target?

| • |  | Yes, there are cell-based assays in place

| • |  | Is cross-reactivity of your final antibody essential (e.g., cross-reactivity to murine, cynomolgus or macaque target)?

| • |  | Cross-reactivity to murine and macaca ortholog mandatory

| • |  | If yes, what is the homology between antigens?

| • |  | Specificity versus family members is mandatory. Family members are also available

| • |  | Could you describe the profile of your “ideal antibody” (e.g., affinity, specificity, mechanism of action, expressability, etc.)?

| • |  | Affinity to human and murine targets: K d ≤ 10 nM and koff ≤ 5x10-4s-1

| • |  | Specificity: selective versus family members and cross reactive with murine and macaca targets. Competes with control mAb provided

| • |  | Do you wish to disrupt a protein-protein interaction (e.g., a receptor-ligand interaction or dimerization)?

| • |  | We do not know at this stage

| • |  | Do you have an existing antibody (murine or other) that binds to your target?

| • |  | Yes

| • |  | If yes, does the antibody have the “biology” you are looking for?

| • |  | We have already mAbs close to what we are looking for, that we’ll use internally for comparison

| • |  | Are you looking to discover an antibody against a known epitope?

| • |  | No

| • |  | Can you describe the desired biological mode of action for the antibodies to be discovered?

| • |  | No

| • |  | What in vitro and in vivo screening assays are you planning to do in-house with purified IgGs discovered by Adimab?

| • |  | Is ADCC expected to be important?

| • |  | ADCC not important
