​

ARTICLE 4​
Co-Development
4.1 Co-Development Plan. Upon designation of Co-Development Product in accordance with Section 3.4(f), both Parties shall jointly discuss and agree to a Co-Development Plan for each Research Program on a 50:50 cost-sharing basis. The cost-sharing would begin from the designation of a Co-Development Product.
4.2 Development Activities and Cost. As set forth in the Co-Development Plan for each Co-Development Program, NextCure shall perform activities related to the process development for manufacturing of CaaX-tagged Antibody to be conjugated using LCB Technology. Both parties will share on a 50:50 basis all development costs, including but not limited to costs for pre-clinical activities, CMC work including raw materials, cGMP manufacturing, QA/QC, stability studies, consultant costs, legal and regulatory expenses, and other external costs directly related to the CMC activities required to support the Development Program, GLP toxicology studies, IND filing, clinical and commercial development as part of the Co-Development Plan. These activities will be coordinated by the JSC and JDT, provided that NextCure will lead the IND submission and clinical trials and LCB will lead the CMC/manufacturing for ADC drug product and drug substance except for the Antibody intermediate manufacturing. For each Co-Development Product a Co-Development Budget should be generated among Parties to set forth the anticipated expenses associated with the Co-Development Plan.
4.3 Cost Distribution Mechanism. The Parties shall calculate and notify each other of the Co-Development Costs as soon as reasonably practicable following the Designation of Co-Development Product in accordance with Section 3.4(f) and thereafter on a continuing basis throughout the Phase 1 Trials. LCB shall provide an itemised breakdown of the Co-Development Costs related to CMC/manufacturing for ADC drug product and drug substance except for the Antibody drug substance manufacturing and shall provide a quarterly invoice to NextCure for 50% of LCB’s Development Costs, and NextCure shall provide an itemised breakdown of the development costs related to Antibody drug substance manufacturing, GLP toxicology studies and Phase 1 Trials and shall provide a quarterly invoice to LCB for 50% of NextCure’s

​
​​

Development Costs. The Parties shall offset the two quarterly invoices against one another such that the only the Party receiving the invoice with the higher amount due for that quarter shall make a payment to the other Party, paying the net balance due (after offsetting) to the other Party within 30 days of receipt the invoices. Such costs under this Section 4.3 shall be determined using a pre-agreed FTE Rate by the Parties as set forth in the respective Co-Development Budget, which FTE Rate will be revisited and revised by the Parties annually.
4.4 Combination Product. The Parties may jointly decide to incorporate the Co-Development Product into a Combination Product through the JSC, in which case the development of such Combination Product would be added to the respective Co-Development Plan and Co-Development Budget and would be jointly funded by the Parties. However, the JSC may alternatively decide to allow a Combination Product to be developed by one Party outside of the Co-Development Plan (provided the Party seeking to perform the combination has control or has sought the necessary licenses to perform the combination), and such developing Party in such cases would develop the Combination Product at such Party’s own expense. The other Party, to the extent it remains active in the Co-Development Plan, in such cases would retain a financial interest in subsequent profits of the Combination Product based on the formula P=A*(B/(B+C)), where P is the proportion of gross profits from the Combination Product that are shareable under this subsection, A is the gross profits from the Combination Product, B is the market price per unit of the incorporated Co-Development Product (where each Party owns 50%) when sold alone, and where C is market price per unit of the combination agent when sold alone. In this case, any profit payments P actually received in association with the combination product shall thereafter be divided equally between the Parties. Notwithstanding the above, the Party seeking to perform the combination shall seek the approval from the other Party to develop the Combination Product, such approval not to be unreasonably withheld.
4.5 Dispute Resolution for Development Cost. If there is any dispute regarding the calculation or distribution of the Development Cost, Parties shall first submit the issue to the JSC to resolve in good faith. If the Parties fail to reach amicable solution in the JSC, Parties shall provide to other Parties with the actual detailed accounting records of expenditure related to this Agreement. Based on such accounting records, Parties shall finalize the expenditure upon mutual consent and adjust the expenditure according to the agreed-upon rate. If Parties fail to reach a mutual consent, upon the written request of a dissenting Party, other Parties shall permit an independent certified public accounting firm of national recognized standing selected by the dissenting Party and reasonably acceptable to the other Parties, at the dissenting Party's expense, to have access during normal business hours to review the records of the other Parties as may be reasonably necessary to verify the accuracy of the accounting records provided hereunder. The accounting firm shall disclose to Parties whether the accounting records are correct or incorrect and the amount of any discrepancy. If such accounting firm correctly identifies a discrepancy made during such period, the appropriate Party shall pay the other Party the amount of the discrepancy

​
​​

within thirty (30) days of the date all the Parties have received such accounting firm's written report. The fees charged by such accounting firm shall be first paid by the dissenting Party as provided above; however, if such audit uncovers a discrepancy in the accounting records for more than five percent (5%) of the total costs, then the fees of such accounting firm shall be paid by the Party with such discrepancy.
4.6 Manufacturing and Supply

ARTICLE 10​
Confidentiality
10.1 Nondisclosure. Each Party agrees that, during the Term and for a period of ten (10) years thereafter, a Party (the “Receiving Party”) receiving Confidential Information of the other Party (the “Disclosing Party”) shall (a) maintain in confidence such Confidential Information using not less than the efforts such Receiving Party uses to maintain in confidence its own confidential or proprietary Information of similar kind and value, (b) not disclose such Confidential Information to any Third Party without the prior written consent of the Disclosing Party, except for disclosures expressly permitted below, and (c) not use such Confidential Information for any purpose except those permitted by this Agreement (it being understood that this Section 9.1 shall not create or imply any rights or licenses not expressly granted under this Agreement). Notwithstanding anything to the contrary in the foregoing, the obligations of confidentiality and non-use with respect to any trade secret within such Confidential Information shall survive such ten (10) year period for so long as such Confidential Information remains protected as a trade secret under Applicable Law.
10.2 Exceptions. The obligations in Section 10.1 shall not apply with respect to any portion of the Confidential Information that the Receiving Party can show by competent written evidence:
(a)is publicly disclosed by the Disclosing Party, either before or after it is disclosed to the Receiving Party hereunder;
(b)is known to the Receiving Party or any of its Affiliates, without any obligation to keep it confidential or any restriction on its use, prior to disclosure by the Disclosing Party;

​
​​

(c)is subsequently disclosed to the Receiving Party or any of its Affiliates on a non-confidential basis by a Third Party that, to the Receiving Party’s Knowledge, is not bound by a similar duty of confidentiality or restriction on its use;
(d)is now, or hereafter becomes, through no act or failure to act on the part of the Receiving Party or any of its Affiliates, generally known or available, either before or after it is disclosed to the Receiving Party;
(e)is independently discovered or developed by or on behalf of the Receiving Party or any of its Affiliates without the use of Confidential Information belonging to the Disclosing Party; or
(f)is the subject of written permission to disclose provided by the Disclosing Party.
10.3 Authorized Disclosure. The Receiving Party may disclose Confidential Information belonging to the Disclosing Party only to the extent such disclosure is reasonably necessary in the following instances:
(a)filing or prosecuting Patents as permitted by this Agreement, provided that no Confidential Information that can be demonstrated as protected as a trade secret is disclosed;
(b)preparing and submitting Regulatory Materials and obtaining and maintaining Regulatory Approvals as permitted by this Agreement;
(c)prosecuting or defending litigation, including responding to a subpoena in a Third-Party litigation;
(d)complying with Applicable Law or court or administrative orders; or
(e)in communications with existing or bona fide prospective acquirers, merger partners, lenders or investors, and consultants and advisors of the Receiving Party in connection with transactions or bona fide prospective transactions with the foregoing, in each case on a “need-to-know” basis and under appropriate confidentiality provisions substantially similar to those of this Agreement; and
(f)to its Affiliates and Third Parties including but not limited to collaborators, sublicensees or prospective sublicensees, Subcontractors or prospective subcontractors, consultants, directors, agents and advisors on a “need-to-know” basis in order for the Receiving Party to exercise its rights or fulfill its obligations under this Agreement, each of whom prior to disclosure must be bound by obligations of confidentiality and restrictions on use of such Confidential Information that are substantially similar to those set forth in this Section 9;

​
​​

provided, however, that, the Receiving Party shall remain responsible for any failure by any Person who receives Confidential Information pursuant to Section 10.3(e) or this Section 10.3(f) to treat such Confidential Information as required under this ARTICLE 10.
(g)If and whenever any Confidential Information is disclosed in accordance with this Section 9.3, such disclosure shall not cause any such information to cease to be Confidential Information except to the extent that such disclosure results in a public disclosure of such information (other than by breach of this Agreement). Notwithstanding the foregoing, in the event a Party is required to make a disclosure of the other Party’s Confidential Information pursuant to clauses (a) through (e) of this Section 10.3, it will, except where impracticable, give reasonable advance notice to the other Party of such disclosure and use not less than the same efforts to secure confidential treatment of such information as it would to protect its own confidential information from disclosure.
10.4 Terms of this Agreement. The Parties acknowledge that this Agreement and all of the respective terms of this Agreement shall be treated as Confidential Information of both Parties subject to the provisions of Sections 10.3, 10.5 and 10.6.
10.5 Publicity. Each Party agrees not to issue any other press release or other public statement disclosing other information relating to this Agreement or the transactions contemplated hereby that contains information not previously publicly disclosed in accordance with this Section 10.5 without the prior written consent of the other Party.
10.6 Securities Filings. Notwithstanding anything to the contrary in this ARTICLE 10, in the event either Party proposes to file with the Securities and Exchange Commission or the securities regulators of any state or other jurisdiction a registration statement or any other disclosure document that describes or refers to the terms and conditions of this Agreement or any related agreements between the Parties, such Party shall notify the other Party of such intention and shall provide the other Party with a copy of relevant portions of the proposed filing at least ten (10) Business Days prior to such filing (and any revisions to such portions of the proposed filing a reasonable time prior to the filing thereof), including any exhibits thereto that refer to the other Party or the terms and conditions of this Agreement or any related Agreements between the Parties. The Party making such filing shall cooperate in good faith with the other Party to obtain confidential treatment of the terms and conditions of this Agreement or any related Agreements between the Parties that the other Party requests be kept confidential or otherwise afforded confidential treatment and shall only disclose Confidential Information that it is reasonably advised by outside counsel is legally required to be disclosed. No such notice shall be required if the description of or reference to this Agreement or a related agreement between the Parties contained in the proposed filing has been included in any previous filing made by the either Party in accordance with this Section 10.6 or otherwise approved by the other Party. The Party making such filing shall not disclose any financial terms

​
​​

of the Agreement or any other related agreements without express written consent of the other Party.
10.7 Relationship to Confidentiality Agreement. This Agreement supersedes the Mutual Confidential Disclosure Agreement between the Parties, as amended, dated January 26, 2022; provided however, that all “Confidential Information” disclosed or received by the Parties and their Affiliates thereunder shall be deemed Confidential Information hereunder and shall be subject to the terms and conditions of this Agreement.
10.8 Equitable Relief. Given the nature of the Confidential Information and the competitive damage that could result to a Party upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages may not be a sufficient remedy for any breach of this ARTICLE 10. In addition to all other remedies, a Party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this ARTICLE 10.
10.9 Publications. Each Party shall ensure that any and all intended publications or presentations to be made public, in case they include the other Party’s Confidential Information, shall be subject to the approval of the other Party and shall be disclosed to the other Party for review at least thirty (30) Days prior to any submission or other public disclosure of such publication or presentation. If the other Party determines that the publication contains patentable subject matter, the publishing Party agrees to postpone publication or presentation of such Presentation for an additional sixty (60) Days to permit the filing of a patent application. If the other Party determines that the publication contains sensitive information, the publishing Party will take comments and suggestions of the other Party into consideration. In any case, each Party shall not publish any publications or presentations in respect of Co-Development Target or Co-Development Product without express written consent of the other Party.

​

ARTICLE 11​
Term and Termination
11.1 Term. This Agreement shall become effective as of the Effective Date and, unless earlier terminated pursuant to this ARTICLE 11, shall continue in full force and effect as long as at least one of the Parties continues to Exploit the Products or Research Programs in accordance with the terms and conditions of this Agreement (the “Term”).
11.2 Termination for Material Breach.

​
​​

(a)Either Party (the “Non-Breaching Party”) may terminate this Agreement in its entirety, and/or on a Co-Development Target-by-Co-Development Target basis, and/or on a country-by-country and/or Product-by-Product basis, in the event the other Party (the “Breaching Party”) has materially breached this Agreement with respect to a Co-Development Target, and/or Product and/or country, and such material breach has not been cured within sixty (60) days after receipt of written notice of such breach by the Breaching Party from the Non-Breaching Party (the “Cure Period”). The written notice describing the alleged material breach shall provide sufficient detail to put the Breaching Party on notice of such material breach. Any termination of this Agreement pursuant to this Section 11.2(a) shall become effective at the end of the Cure Period, unless the Breaching Party has cured any such material breach prior to the expiration of such Cure Period, or, if such material breach is not susceptible to cure within the Cure Period, then, the Non-Breaching Party’s right of termination shall be suspended only if and for so long as the Breaching Party has provided to the Non-Breaching Party a written plan that is reasonably calculated to effect a cure of such material breach, such plan is accepted by the Non-Breaching Party (such acceptance not to be unreasonably withheld, conditioned, or delayed), and the Breaching Party commits to and carries out such plan as provided to the Non-Breaching Party no later than one hundred fifty (150) days after written notice of said breach. The right of either Party to terminate this Agreement, whether in part or in its entirety, as provided in this Section 11.2(a) shall not be affected in any way by such Party’s waiver of or failure to take action with respect to any previous breach under this Agreement.
(b)If the Parties reasonably and in good faith disagree as to whether there has been a material breach, the Party that disputes whether there has been a material breach may contest the allegation in accordance with ARTICLE 12. Notwithstanding anything to the contrary contained in Section 11.2(a), the Cure Period for any Dispute will be tolled from the date that written notice was first provided to the Breaching Party by the Non-Breaching Party through the resolution of such Dispute pursuant to ARTICLE 12, and it is understood and acknowledged that, during the pendency of a Dispute pursuant this Section 11.2(b), all of the terms and conditions of this Agreement shall remain in effect, and the Parties shall continue to perform all of their respective obligations under this Agreement. Any payments that are made by one Party to the other Party pursuant to this Agreement pending resolution of the Dispute shall be promptly refunded if it is determined pursuant to ARTICLE 12 that such payments are to be refunded by one Party to the other Party.
11.3 Termination for Bankruptcy.
(a)Either Party may terminate this Agreement in its entirety upon providing written notice to the other Party on or after the time that such other Party makes a general assignment for the benefit of creditors, files an insolvency petition in bankruptcy, petitions for or acquiesces in the appointment of any receiver, trustee or similar officer to liquidate or conserve its business or any substantial part of its assets, commences under the laws of any

​
​​

jurisdiction any proceeding involving its insolvency, bankruptcy, reorganization, adjustment of debt, dissolution, liquidation or any other similar proceeding for the release of financially distressed debtors, or becomes a party to any proceeding or action of the type described above, and such proceeding or action remains un-dismissed or un-stayed for a period of more than sixty (60) days.
(b)All rights and licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes of Section 365(n) of Title 11 of the United States Code and other similar laws in any jurisdiction outside the U.S. (collectively, the “Bankruptcy Laws”), licenses of rights to “intellectual property” as defined under the Bankruptcy Laws. If a case is commenced during the Term by or against a Party under Bankruptcy Laws then, unless and until this Agreement is rejected as provided pursuant to such Bankruptcy Laws, such Party (in any capacity, including debtor-in-possession) and its successors and assigns (including a Title 11 trustee) shall perform all of the obligations in this Agreement intended to be performed by such Party. If a case is commenced during the Term by or against a Party under the Bankruptcy Laws, this Agreement is rejected as provided for under the Bankruptcy Laws, and the non-bankrupt Party elects to retain its rights hereunder as provided for under the Bankruptcy Laws, then the Party subject to such case under the Bankruptcy Laws (in any capacity, including debtor-in-possession) and its successors and assigns (including a Title 11 trustee), shall provide to the non-bankrupt Party copies of all Patents and Information necessary for the non-bankrupt Party to prosecute, maintain and enjoy its rights under the terms of this Agreement. All rights, powers and remedies of the non-bankrupt Party as provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including the Bankruptcy Laws) in the event of the commencement of a case by or against a Party under the Bankruptcy Laws. In particular, it is the intention and understanding of the Parties to this Agreement that the rights granted to the Parties under this Section 11.3 are essential to the Parties’ respective businesses and the Parties acknowledge that damages are not an adequate remedy. The Parties acknowledge and agree that the payments made under Section 5.1 shall not (i) constitute royalties within the meaning of Section 365(n) of the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, or (ii) relate to licenses of intellectual property hereunder.
11.4 Termination for Delayed or Abandoned Development. This Section 11.4 shall not limit a Party’s right to terminate pursuant to Section 11.2 (Termination for Material Breach) and 11.3 (Termination for Bankruptcy). Each Party may terminate a Co-Development Target and/or Co-Development Product by providing notice in writing to the other Party if in the absence of Commercially Reasonable Efforts or any force majeure event such other Party suspends or otherwise fails to conduct any Development activities for a corresponding Research Program or Co-Development Product for twelve (12) consecutive months or more during the

​
​​

Term, such notice to take effect with respect to such Co-Development Target and/or Co-Development Product sixty (60) calendar days from the other Party’s receipt of such notice. Additionally, each Party may terminate a Co-Development Target and/or Co-Development Product by providing notice in writing to the other Party if such other Party has first informed such Party (e.g., at a committee meeting or otherwise) that such other Party will not be participating further in the joint funding and/or advancement of a Co-Development Target and/or Co-Development Product, such notice to take effect with respect to such Co-Development Produce and/or Co-Development Product immediately upon receipt.
11.5 Effects of Termination. All of the following effects of termination are in addition to the other rights and remedies that may be available to either of the Parties under this Agreement and shall not be construed to limit any such rights or remedies. In the event this Agreement is not terminated in its entirety, but rather is terminated on a Co-Development Target-by-Co-Development Target basis (each such terminated Co-Development Target, a “Terminated Target”) and/or Product-by-Product and/or country-by-country basis with respect to one or more Products (each such terminated Product, a “Terminated Product”), then, notwithstanding anything to the contrary contained in Section 11.5(a), the consequences of termination described under this Section 11.5 shall only apply to the Terminated Target or Terminated Product, as the case may be, and this Agreement shall remain in full force and effect in accordance with its terms with respect to all Products and all other Co-Development Targets other than the Terminated Targets or Terminated Products, in all countries of the Territory.
(a)Consequences of Termination by LCB or NextCure. In the event of termination of this Agreement with respect to any Research Program Target and/or Co-Development Target, Product and/or in its entirety by either Party:
(i)Without limiting the effect that such termination shall have on any provisions of this Agreement, other than those provisions that this Agreement expressly provides shall survive such termination and subject to this Section 11.5(a), all rights and licenses granted herein to either Party shall terminate, and the Parties, except to the extent a Party is a Sole Developing Party for a particular Terminated Product or Terminated Target, shall cease any and all Development, Manufacturing, and commercialization activities with respect to the Terminated Targets and/or Terminated Products in the Terminated Countries, as the case may be, as soon as is reasonably practicable under Applicable Law; provided that such licenses shall continue as necessary for the Parties to complete the orderly wind-down of their activities under this Agreement (including to enable an orderly transition of materials, activities and responsibilities to a Sole Developing Party as applicable) in accordance with Applicable Law and as otherwise required in accordance with Section 11.5(a)(i);

​
​​

(ii)Except as set forth in Section 11.5(a)(iv) below, all payment obligations hereunder shall terminate, other than those that are accrued and unpaid as of the effective date of such termination;
(iii)All exclusivity obligations hereunder shall terminate with respect to such Terminated Target or Terminated Products.
(iv)After termination of the Agreement or any Research Programs generated under the Collaboration under Section 11.4 the terminating Party may choose to continue to Develop the Product or any Research Programs on its own exclusively (such Party continuing Development thereafter being deemed a “Sole Developing Party” with respect to the so-continued Product and/or Research Targets, and the other Party thereafter being deemed a “Non-developing Party” with respect to such Product and/or Research Target). The Non-developing Party shall grant, and hereby grants, to the Sole Developing Party in each case an exclusive license under its respective Patents and Know How (including its joint share of rights in any Research Program Technology) that are necessary or reasonably useful to Develop, Manufacture, and Exploit the so-continued Product and/or Research Target in the Field in the Territory (“Reversion Technology”) in accord with this Section 11.5. The Non-developing Party shall provide access to know-how, documentation, materials and technology transfer with respect to the Reversion Technology to support development of such Product and Research Programs to the Sole Developing Party. In such cases, the Sole Developing Party shall pay development and commercial milestone and royalty payments to the Non-developing Party for each Research Program, including the B7-H4 ADC Program, as specified in Exhibit B. The Sole Developing Party shall provide to the Non-developing Party a report detailing the Sole Developing Party's material efforts and progress with respect to the Research Program and the so-continued Products within sixty (60) days after January 1 of each Calendar Year. Each such report shall describe, among other matters, those: (A) material Development activities initiated, currently in progress and completed during the Calendar Year, and (B) material Development activities planned to be initiated during the next Calendar Year. Each Sole Developing Party will retain licenses granted under this Section 11.5(a)(iv) under the Reversion Technology from the Non-Developing Party as reasonably necessary to Develop, Manufacture and Exploit those respective Products and Research Programs for so long as such Party continues to Develop and Exploit such Products and Research Programs. Notwithstanding the foregoing, in the absence of Commercially Reasonable Efforts or any force majeure event, if the Sole Developing Party suspends or otherwise fails to conduct any Development activities for a Research Program for twelve (12) consecutive

​
​​

months or more, the Non-developing Party may terminate the Agreement and the exclusive license granted in accordance with this Section 11.5(a)(iv) with a written notice, with such notice to take effect with respect to such Research Program sixty (60) calendar days from the Sole Developing Party's receipt of such notice.
(v)For clarity, if a Research Program is terminated, this Agreement shall continue to remain effective, unless all Research Programs generated under the Agreement including all Co-Development Products are terminated and all Sole Developing Parties cease to Develop, commercialize, and/or otherwise Exploit any Terminated Targets and/or Terminated Products.
(vi)Technology Transfer and Inventory. To permit the Sole Developing Party to pursue its continuing rights under Section 11.5(a)(iv) and upon reasonable request, the Non-developing Party shall provide to such Sole Developing Party reasonable technology transfer assistance, including reasonably requested documents or other information that the Parties have created concerning the Terminated Targets and Terminated Products and concerning processes or Know How that otherwise are reasonably necessary to support manufacturing or testing of relevant Terminated Targets and Terminated Products. Further, upon termination a Party may request to procure any unsold or unused inventory stocks of the Co-Development Products from the other Party. Such stocks shall be provided at a transfer price to be negotiated by the Parties, with the proviso that such price shall take into account any prior cost sharing between the Parties with regard to the inventory prior to such termination.
(vii)Return of Confidential Information. Subject to the rights of a Sole Developing Party granted in subparagraphs (iv) and (vi) above, upon any termination of this Agreement, the Receiving Party shall return to the Disclosing Party or otherwise destroy any documents or other materials that contain the Disclosing Party’s Confidential Information in relation to the Terminated Product or Terminated Target, including all copies made, and make no further use or disclosure thereof. The Receiving Party may, however, keep copies of the Confidential Information of the Disclosing Party in its legal adviser’s files and in internal IT backup systems solely for the purpose of enabling it to comply with the provisions of this Agreement.
11.6 Remedies. Notwithstanding anything to the contrary in this Agreement, except as otherwise set forth in this Agreement, termination or expiration of this Agreement shall not relieve the Parties of any liability or obligation which accrued hereunder prior to the effective date of such termination or expiration, nor prejudice either Party’s right to obtain performance of any obligation. Each Party shall be free, pursuant to Section 11, to seek, without restriction

​
​​

as to the number of times it may seek, damages, expenses and remedies that may be available to it under Applicable Law or in equity and shall be entitled to offset the amount of any damages and expenses obtained against the other Party in a final determination under Article 12, against any amounts otherwise due to such other Party under this Agreement.
11.7 Survival. In the event of termination of this Agreement, in addition to the provisions of this Agreement that continue in effect in accordance with their terms, the following provisions of this Agreement shall survive: Articles 1, 7, 8, 9, 10, 11, 12 and 14 and Section 6.1 with respect to any Products being Developed and/or Exploited by a Sole Developing Party.
ARTICLE 12​
Dispute Resolution
12.1 Disputes. Any dispute between the Parties arising out of or relating to the Agreement, including any non-contractual disputes or claims or any question regarding its existence, validity, or termination, shall be resolved by binding arbitration. The proceedings shall be initiated by the service of a written notice of dispute by a Party on the other Party setting out details of the dispute and the reasons why the Party serving the notice believes that the dispute has arisen. Upon service of such a notice, the dispute shall be referred to the Senior Officers (or their respective delegates), who shall endeavour to resolve the dispute amicably (each acting reasonably and in good faith).
12.2 Arbitration. In the event that a dispute cannot be resolved to the satisfaction of both Parties within 30 Days of referral to the Senior Officers (or their respective delegates), or if a Party either fails to participate or to continue to participate in the process referred to in Section 12.1 (Disputes), it shall be finally settled through an arbitration in accordance with the Rules of Arbitration of the International Chamber of Commerce 2021 in accordance with the Expedited Procedure Rules irrespective of the amount in dispute. The right and obligation to arbitrate under this Section 12.2 (Arbitration) shall extend to any claims by or against the Parties and their respective Affiliates and any agents, principals, officers, directors, or employees of either of the Parties or their respective Affiliates. The arbitration tribunal shall be composed of one arbitrator agreed by the Parties. If the Parties are unable to agree on an arbitrator within 30 Days after the transmission of the request for arbitration by one of the Parties, then the arbitration tribunal shall be composed of one arbitrator selected by each Party and one arbitrator selected by the first two arbitrators. The arbitral award shall be final and binding. A judgment on any award rendered by the arbitrator(s) may be entered in any court having jurisdiction thereof. The legal seat of arbitration shall be Southern District of New York, and the language of the arbitral proceedings shall be English. Either party may apply to the arbitrator(s) seeking injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. The arbitrators shall have the authority to grant specific performance, issue summary judgments or grant other depository motions and, if either Party engages attorneys to enforce any rights arising out of or

​
​​

relating to the Agreement, then the prevailing Party shall be entitled to recover its reasonable fees and costs expended in engaging such attorneys. The Parties agree that all information, including the result, of such arbitration and the fact that arbitration takes place shall be regarded as Confidential Information of both Parties and shall not be disclosed without the written consent of the other Party.
ARTICLE 13​
Indemnification
13.1 Indemnification by NextCure. NextCure hereby agrees to defend, indemnify and hold harmless LCB and its Affiliates and each of their respective directors, officers, employees, agents and representatives (each, a “LCB Indemnitee”) from and against any and all claims, suits, actions, demands, liabilities, expenses and/or losses, including reasonable legal expenses and attorneys’ fees (collectively, the “Losses”) to which any LCB Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Third Party (each, a “Claim”) to the extent such Losses arise directly or indirectly out of: (a) the breach by NextCure of any warranty, representation, covenant or agreement made by NextCure in this Agreement; and (b) the negligence, gross negligence, illegal conduct, or wilful misconduct (including to the extent such negligence, gross negligence, illegal conduct or wilful misconduct gives rise to product liability Claims under any legal theory) of NextCure or its Affiliate or its licensee (other than LCB or its Affiliate or sublicensee), or any officer, director, employee, agent or representative thereof; except, with respect to each of subsections (a) and (b) above, to the extent such Losses arise directly or indirectly from the negligence, gross negligence, illegal conduct or wilful misconduct of any LCB Indemnitee or the breach by LCB of any warranty, representation, covenant or agreement made by LCB in this Agreement.
13.2 Indemnification by LCB. LCB hereby agrees to defend, indemnify and hold harmless NextCure and its Affiliates and each of their respective directors, officers, employees, agents and representatives (each, a “NextCure Indemnitee”) from and against any and all Losses to which any NextCure Indemnitee may become subject as a result of any Claim to the extent such Losses arise directly or indirectly out of: (a) the breach by LCB of any warranty, representation, covenant or agreement made by LCB in this Agreement; and (b) the negligence, gross negligence, illegal conduct, or wilful misconduct (including to the extent such negligence, gross negligence, illegal conduct or wilful misconduct gives rise to product liability Claims under any legal theory) of LCB or its Affiliate or its licensee (other than NextCure or its Affiliate or sublicensee), or any officer, director, employee, agent or representative thereof; except, with respect to each of subsections (a) and (b) above, to the extent such Losses arise directly or indirectly from the negligence, gross negligence, illegal conduct or wilful misconduct of any NextCure Indemnitee or the breach by NextCure of any warranty, representation, covenant or agreement made by NextCure in this Agreement.

​
​​

13.3 Indemnification by Sole Commercializing Party. Both Parties, to the extent they are a Sole Developing Party commercializing a respective Product in accord with Section 7.2(a) and Section 11.5(a)(iv), hereby agrees to defend, indemnify and hold harmless the non-commercializing Party and its Affiliates, and each of their respective directors, officers, employees, agents and representatives (each, a “Non-Developing Indemnitee”) from and against any and all Losses to which any Non-Developing Indemnitee may become subject to as a result of any Claim the extent such Losses arise directly or indirectly out of: (a) the practice by the Sole Developing Party or its Affiliate or their respective sublicensee of any license granted to it under Section 11.5(a)(iv) with respect to the Research Program Technology and/or the technology of the non-commercializing Party; and (b) the manufacture, use, handling, storage, sale, marketing, export, import, other disposition or Exploitation of any Product by the Sole Developing Party or its Affiliate or their respective sublicensee, including any Product Liabilities related to the use or Exploitation of the Product.
13.4 Indemnification Procedures.
(a)Notice. Promptly after a Non-Developing Indemnitee, LCB Indemnitee or a NextCure Indemnitee (each, an “Indemnitee”) receives notice of a pending or threatened Claim, such Indemnitee shall give written notice of the Claim to the Party from whom the Indemnitee is entitled to receive indemnification pursuant to Sections 13.1 through 13.3, as applicable (the “Indemnifying Party”). However, an Indemnitee’s delay in providing or failure to provide such notice will not relieve the Indemnifying Party of its indemnification obligations, except to the extent it can demonstrate prejudice due to the delay or lack of notice.
(b)Defense. Upon receipt of notice under Section 13.4 from the Indemnitee, the Indemnifying Party shall have the duty to either compromise or defend, at its own expense and by counsel (reasonably satisfactory to Indemnitee), such Claim. The Indemnifying Party shall promptly (and in any event not more than twenty (20) days after receipt of the Indemnitee’s original notice) notify the Indemnitee in writing that it acknowledges its obligation (which acknowledgement shall not be deemed or construed as an admission of liability, either under this ARTICLE 13 or otherwise) to indemnify the Indemnitee with respect to the Claim pursuant to this Section 13.4 and of its intention either to compromise or defend such Claim. Once the Indemnifying Party gives such notice to the Indemnitee, the Indemnifying Party is not liable to the Indemnitee for the fees of other counsel or any other expenses subsequently incurred by the Indemnitee in connection with such defense, other than the Indemnitee’s reasonable expenses of investigation and cooperation. However, the Indemnitee shall have the right to employ separate counsel and to control the defense of a Claim at its own expense.
(c)Cooperation. The Indemnitee shall cooperate fully with the Indemnifying Party and its legal representatives in the investigation and defense of any Claim. The Indemnifying Party shall keep the Indemnitee informed on a reasonable and timely basis

as to the status of such Claim (to the extent the Indemnitee is not participating in the defense of such Claim) and conduct the defense of such Claim in a prudent manner.
(d)Settlement. If an Indemnifying Party assumes the defense of a Claim, no compromise or settlement of such Claim may be effected by the Indemnifying Party without the Indemnitee’s written consent (such consent not to be unreasonably withheld, delayed or conditioned). Notwithstanding the foregoing, the Indemnitee’s consent shall not require of a settlement where: (i) there is no finding or admission of any violation of law or any violation of the rights of any person and no effect on any other claims that may be made against the Indemnitee; (ii) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party; and (iii) the Indemnitee’s rights under this Agreement are not adversely affected. If the Indemnifying Party fails to assume defense of a Claim within a reasonable time, the Indemnitee may settle such Claim on such terms as it deems appropriate with the consent of the Indemnifying Party (such consent not to be unreasonably withheld, delayed or conditioned), and the Indemnifying Party shall be obligated to indemnify the Indemnitee for such settlement as provided in this ARTICLE 13.
13.5 Insurance. Each Party shall, at its own expense, procure and maintain during the Term insurance policy/policies, including product liability insurance where applicable given the development stage of the Co-Development Product, adequate to cover its obligations hereunder and which are consistent with usual business practices of prudent companies similarly situated. Such insurance shall not be construed to create a limit of the Party’s liability with respect to its indemnification obligations under this ARTICLE 13. The Parties shall provide the other Party with prompt written notice of cancellation, non-renewal or material change in such insurance or self-insurance that could materially adversely affect the rights of the Parties hereunder and shall provide such notice within thirty (30) days after any such cancellation, non-renewal or material change.
13.6 Limitation of Liability. EXCEPT FOR A PARTY’S OBLIGATIONS SET FORTH IN THIS SECTION 13, AND ANY BREACH OF SECTION 10 (CONFIDENTIALITY), IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY (OR THE OTHER PARTY’S AFFILIATES OR SUBLICENSEES) IN CONNECTION WITH THIS AGREEMENT FOR LOST REVENUE, LOST PROFITS, LOST SAVINGS, LOSS OF USE, DAMAGE TO GOODWILL, OR ANY CONSEQUENTIAL, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE OR INDIRECT DAMAGES UNDER ANY THEORY, INCLUDING CONTRACT, NEGLIGENCE, OR STRICT LIABILITY, EVEN IF THAT PARTY HAS BEEN PLACED ON NOTICE OF THE POSSIBILITY OF SUCH DAMAGES.

14.3 Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by 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. Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a Force Majeure affecting such Party. If a Force Majeure persists for more than ninety (90) days, then the Parties shall discuss in good faith the modification of the Parties’ obligations under this Agreement in order to mitigate the delays caused by such Force Majeure.
14.4 Assignment.
(a)Subject to Section 14.4(b), neither Party may assign, mortgage, charge, or otherwise transfer any rights or obligations under the Agreement without the prior written consent of the other Party.
(b)With written notice to the other Party before such assignment or transfer, either Party may assign and transfer all its rights and obligations under the Agreement to an Affiliate. A Party may assign this Agreement with notice to the other Party to (i) a Third Party in case of a sale of substantially all of such Party’s assets relating to one or more Co-Development Products and/or Co-Development Targets to such Third Party, or (iii) to a successor in interest in the case of a merger, acquisition, or other change of control transaction. In all cases, the assignee must undertake in writing to the non-assigning Party to be bound by and perform the obligations of the assignor under the Agreement. Any assignment or attempted assignment by either Party in violation of the terms of this Section 14.4 (Assignment) will be null, void and of no legal effect.
14.5 Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, the provision shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized.
14.6 English Language. This Agreement shall be written and executed in, and all other communications under or in connection with this Agreement, shall be in the English language. Any translation into any other language shall not be an official version thereof, and in the event of any conflict in interpretation between the English version and such translation, the English version shall control.
14.7 Waiver and Non-Exclusion of Remedies. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on

​
​​

behalf of the Party waiving such term or condition. The waiver by either Party hereto of any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by such other Party whether of a similar nature or otherwise. The rights and remedies provided herein are cumulative and do not exclude any other right or remedy provided by Applicable Law or otherwise available except as expressly set forth herein.
14.8 Further Assurance. Each Party shall duly execute and deliver, or cause to be duly executed and delivered, such further instruments and do and cause to be done such further acts and things, including the filing of such assignments, agreements, documents, and instruments, as may be necessary or as the other Party may reasonably request in connection with this Agreement or to carry out more effectively the provisions and purposes hereof.
14.9 Relationship of the Parties. It is expressly agreed that this Agreement does not create or constitute a partnership, joint venture or agency, including for tax purposes. Neither LCB nor NextCure shall have the authority to make any statements, representations or commitments of any kind, or to take any action which shall be binding on the other, without the prior written consent of the other Party to do so. All persons employed by a Party shall be employees of that Party and not of the other Party and all expenses and obligations incurred by reason of such employment shall be for the account and expense of such Party.
14.10 Construction. Except where the context otherwise requires, wherever used, the singular shall include the plural, the plural shall include the singular, and the use of any gender shall be applicable to all genders. Whenever this Agreement refers to a number of days without using a term otherwise defined herein, such number refers to calendar days. The captions of this Agreement are for the convenience of reference only and in no way define, describe, extend, or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement. The terms “including,” “include,” “includes” or “for example” shall not limit the generality of any description preceding such term and as used herein shall have the same meaning as “including, but not limited to” or “including, without limitation.” The language of this Agreement shall be deemed to be the language mutually chosen by the Parties and no rule of strict construction shall be applied against either Party hereto. Each Party represents that it has been represented by legal counsel in connection with this Agreement and acknowledges that it has participated in the drafting hereof. In interpreting and applying the terms and provisions of this Agreement, the Parties agree that no presumption will apply against the Party which drafted such terms and Provision.
14.11 Governing Laws. This Agreement was prepared in the English language, which language shall govern the interpretation of, and any dispute regarding, the terms of this Agreement. This Agreement and all disputes arising out of or related to this Agreement or any breach hereof shall be governed by and construed under the laws of the State of New York,

No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party. In the event of any inconsistency between the body of this Agreement and either any Exhibits to this Agreement or any subsequent agreements ancillary to this Agreement, unless otherwise express stated to the contrary in such Exhibit or ancillary agreement, the terms contained in this Agreement shall control.
14.13 Headings. The headings of each Section and Sections in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Section or Sections.
