4.3 Royalty Term. Royalties hereunder shall be payable on a Product-by-Product and country-by-country basis in the Territory during the period of time commencing on the First Commercial Sale of a Product in a country of the Territory and ending upon expiration of the later to occur of (a) the last-to-expire Valid Claim of the BioAtla Licensed Patents and Company Licensed Patents covering the manufacture, use, sale, offer for sale or import of such Product in such country, (b) the tenth (10^th) anniversary following the First Commercial Sale in such country and (c) the expiration of Regulatory Exclusivity for such Product in such country (the “Royalty Term”). On a Product-by-Product and country-by-country basis, upon expiration of the Royalty Term for a Product in a country of Territory, the Company’s license hereunder with respect to such Product in such country shall become fully-paid, irrevocable and perpetual.

4.4 Payment; Reports. Royalties hereunder shall be calculated and reported for each calendar quarter and shall be paid within 60 days after the end of each calendar quarter. Each payment shall be accompanied by a report of Net Sales of Products by the Company, its Affiliates and Licensees, which report shall include the gross sales and Net Sales of each Product, the royalties payable, a description of the method used to calculate the royalties payable, and the exchange rates used, in each case presented on an Product-by-Product and country-by-country basis.

4.5 Exchange Rate; Manner and Place of Payment. All payments under this Article 4 shall be payable in U.S. dollars by wire transfer in immediately available funds to a bank and account designated in writing by BioAtla. When conversion of payments from any foreign currency is required, such conversion shall be made at the rate of exchange used throughout the accounting system of the Company and its Affiliates for the applicable period.

4.6 Audits. The Company shall keep (and shall cause its Affiliates and Licensees to keep) complete and accurate records pertaining to the sale or other disposition of Products in sufficient detail to permit BioAtla to confirm the accuracy of all royalty payments due hereunder for a period of three years from the end of the calendar year to which such records relate. BioAtla shall have the right, once annually, to cause an independent, certified public accountant reasonably acceptable to the Company (the “Auditor”) to audit such records solely to confirm Net Sales and royalties for a period covering not more than the preceding three years. Such audits may be exercised during normal business hours upon reasonable prior written notice to the Company. No calendar year shall be subject to audit under this section more than once. The Auditor will execute a reasonable written confidentiality agreement with the Company and will disclose to BioAtla only such information as is reasonably necessary to provide BioAtla with information regarding any actual or potential discrepancies between amounts reported and actually paid and amounts payable under this Agreement. The Auditor will send a copy of the report to the Company at the same time it is sent to BioAtla. The report sent to both parties will include the methodology and calculations used to determine the results. Prompt adjustments shall be made by the parties to reflect the results of such audit. BioAtla shall bear the full cost of such audit unless such audit discloses an underpayment by the Company of more than 5% of the amount due for any calendar year under this Agreement, in which case, the Company shall bear the full cost of such audit and shall promptly remit to BioAtla the amount of any underpayment. If such audit discloses an overpayment by the Company, then the Company will deduct the amount of such overpayment from amounts otherwise owed to BioAtla under this Agreement.

13.

4.7 Withholding. BioAtla will pay any and all taxes levied on account of any payments made to it under this Agreement. If any taxes are paid or required to be withheld by the Company for the benefit of BioAtla on account of any amounts payments payable to BioAtla hereunder, the Company will deduct such taxes from the amount of payments otherwise due to BioAtla, timely pay the taxes to the proper taxing authority, and send proof of payment to BioAtla within 30 days following such payment.

4.8 Late Payments. In the event that any payment due under Section 4.1 (other than any invoiced amount or portion thereof that is subject to good faith dispute between the parties) is not made when due, the payment shall accrue interest from the date due at the rate of 1.0% per month; provided, however, that in no event shall such rate exceed the maximum legal annual interest rate. The payment of such interest shall not limit BioAtla from exercising any other rights it may have as a consequence of the lateness of any payment.

5.	CONFIDENTIALITY.

5.1 Confidential Information. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the parties, each party agrees that, during the Term, and for five years thereafter, such party (the “Receiving Party”) shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as expressly provided for in this Agreement any Information furnished to it by the other party (the “Disclosing Party”) pursuant to this Agreement, the Confidentiality Agreement (the “Confidential Information”). Notwithstanding the foregoing, the parties hereby agree that: (a) each timeline and budget set forth under any Project Plan shall be considered the Confidential Information of both parties, and each party be deemed the Disclosing Party and the Receiving Party with respect thereto; (b) the terms of this Article 5 shall supersede the Confidentiality Agreement; and (c) any Information disclosed by a party pursuant to the Confidentiality Agreement shall be deemed Confidential Information of such party for purposes of this Agreement. The Receiving Party may use Confidential Information only to the extent required to accomplish the purposes of this Agreement. The Receiving Party will use at least the same standard of care as it uses to protect proprietary or Confidential Information of its own, but no less than reasonable care, to ensure that its employees, agents, consultants and other representatives do not disclose or make any unauthorized use of the Confidential Information. The Receiving Party will promptly notify the Disclosing Party upon discovery of any unauthorized use or disclosure of the Confidential Information.

5.2 Exceptions. Confidential Information shall not include any information which: (a) is now, or hereafter becomes, through no act or failure to act on the part of the Receiving Party in breach of this Agreement, publicly known or available; (b) is known by the Receiving Party at the time of receiving such information (other than as a result of disclosure by or on behalf of the Disclosing Party), as evidenced by its records; provided, however, that the exception set forth in this clause (b) shall not apply to results, or to any timeline and budget under any Project Plan; (c) is hereafter furnished to the Receiving Party by a Third Party, as a matter of right and without restriction on disclosure; or (d) is independently discovered or developed by the Receiving Party

14.

outside of a Project Plan and without the use of Confidential Information of the Disclosing Party. For purposes of clause (a) of this Section, no combination of elements within the Confidential Information shall be deemed to be part of the public domain merely because the individual elements of such combination are part of the public domain, unless the entire combination itself, or the entire principle of use or operation of such combination (if any), is part of the public domain. In addition, no element within the Confidential Information shall be deemed to be a part of the public domain merely because it is embraced by more general information or data that is part of the public domain.

5.3 Authorized Disclosure. A Receiving Party may disclose Confidential Information of the Disclosing Party as expressly permitted by this Agreement (including as reasonably necessary for the Receiving Party’s performance of its obligations under this Agreement), or if and to the extent such disclosure is reasonably necessary in the following instances:

(a) prosecuting or defending Litigation as permitted by this Agreement;

(b) complying with requests of government agencies, applicable court orders, Applicable Laws, rules or regulations, or the listing rules of any exchange on which the Receiving Party’s or its Affiliate’s securities are traded;

(c) enforcing the Receiving Party’s rights under this Agreement;

(d) filing or prosecuting Patent Rights as permitted by this Agreement;

(e) in the case of the Company, disclosure in regulatory submissions with respect to Products within the scope of the Exclusive License;

(f) in the case of BioAtla, disclosure in regulatory submissions with respect to Products within the scope of the Exclusive Non-CAST License;

(g) disclosure to the Receiving Party’s Affiliates, to the Company’s actual or potential licensees or sublicensees of rights with respect to Products in the Field, to BioAtla’s actual or potential licensees or sublicensees of rights with respect to Products outside the Field, and to the Receiving Party’s and its Affiliates’ representatives who, in each case, have a need to know such information in order for the Receiving Party to exercise its rights or fulfill its obligations under this Agreement, provided, in each case, that any such Affiliate, actual or potential licensee or sublicensee, or representative agrees to be bound by terms of confidentiality and non-use at least as restrictive as those set forth in this Article; and

(h) disclosure to Third Parties in connection with due diligence or similar investigations by such Third Parties, and disclosure to potential Third Party investors in confidential financing documents, provided, in each case, that any such Third Party agrees to be bound by reasonable obligations of confidentiality and non-use.

Notwithstanding the foregoing, in the event the Receiving Party is required to make a disclosure of the Disclosing Party’s Confidential Information pursuant to this Section 5.3, it will, except where impracticable, (i) give reasonable advance notice to the Disclosing Party of such disclosure, (ii) use efforts to secure confidential treatment of such information at least as diligent as the Receiving Party would use to protect its own Confidential Information, but in no event less than reasonable efforts, and (iii) cooperate with any efforts by the Disclosing Party, at the Disclosing Party’s request and expense, to secure confidential treatment of such Confidential Information.

BioAtla hereby agrees to save, defend, indemnify and hold harmless the Company, its Affiliates and their respective officers, directors, employees, consultants and agents (the “Company Indemnitees”) from and against any and all Losses to which any Company Indemnitee may become subject as a result of any Claim to the extent such Losses arise out of or relate to: (a) the development, manufacture, use, handling, storage, sale, offer for sale, import or other disposition by or on behalf of BioAtla, its Affiliates, licensees or sublicensees of Products outside the Field, involving the exercise of the Exclusive Non-CAST License by or on behalf of BioAtla, its Affiliates, licensees or sublicensees; (b) the gross negligence or willful misconduct of any BioAtla Indemnitee; or (c) the breach by BioAtla of any warranty, representation, covenant or agreement made by BioAtla in this Agreement; in each case except to the extent such Losses result from the gross negligence or willful misconduct of any Company Indemnitee or the breach by the Company of any warranty, representation, covenant or agreement made by the Company in this Agreement.

9.3 Control of Defense. In the event a party (the “Indemnified Party”) seeks indemnification under Section 9.1 or 9.2, it shall inform the other party (the “Indemnifying Party”) of a claim as soon as reasonably practicable after it receives notice of the claim (it being understood and agreed, however, that the failure by an Indemnified Party to give notice of a claim as provided in this Section 9.3 shall not relieve the Indemnifying Party of its indemnification obligation under this Agreement except and only to the extent that such Indemnifying Party is actually damaged as a result of such failure to give notice), shall permit the Indemnifying Party to assume direction and control of the defense of the claim (provided that such claim is solely for monetary damages and the Indemnifying Party agrees to pay all damages relating to such matter, as evidenced in a written confirmation delivered by the Indemnifying Party to the Indemnified Party) using counsel reasonably satisfactory to the Indemnified Party, and shall cooperate as requested (at the expense of the Indemnifying Party) in the defense of the claim. If the Indemnifying Party does not assume control of such defense within 15 days after receiving notice of the claim from the Indemnified Party, the Indemnified Party shall control such defense and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party shall reimburse the Indemnified Party for all costs, including reasonable attorney fees, incurred by the Indemnified Party in defending itself within 30 days after receipt of any invoice therefor from the Indemnified Party. The party not controlling such defense may participate therein at its own expense. The party controlling such defense shall keep the other party advised of the status of such action, suit, proceeding or claim and the defense thereof and shall consider recommendations made by the other party with respect thereto. The Indemnified Party shall not agree to any settlement of such action, suit, proceeding or claim without the prior written consent of the

24.

Indemnifying Party, which shall not be unreasonably withheld, delayed or conditioned. The Indemnifying Party shall not agree to any settlement of such action, suit, proceeding or claim or consent to any judgment in respect thereof that does not include a complete and unconditional release of the Indemnified Party from all liability with respect thereto, that imposes any liability or obligation on the Indemnified Party or that acknowledges fault by the Indemnified Party without the prior written consent of the Indemnified Party. If the parties cannot agree as to the application of Section 9.1 or 9.2 to any claim, pending resolution of the Dispute pursuant to Article 10, the parties may conduct separate defenses of such claims, with each party retaining the right to claim indemnification from the other party in accordance with Section 9.1 or 9.2, as applicable, upon resolution of the underlying claim.

9.4 Insurance. Each party shall procure and maintain insurance, including comprehensive or commercial general liability insurance (including contractual liability and product liability), adequate to cover its obligations hereunder and which is consistent with normal business practices of prudent companies similarly situated. It is understood that such insurance shall not be construed to create a limit of either party’s liability with respect to its indemnification obligations under this Article 9 or otherwise. Each party shall provide the other party with written evidence of such insurance upon request.

10.

DISPUTE RESOLUTION.

10.1 Disputes. Subject to Section 10.3, any claim, dispute, or controversy as to the breach, enforcement, interpretation or validity of this Agreement (each, a “Dispute”) will be referred to the Chief Executive Officer of the Company and the Chief Executive Officer of BioAtla (the “Executives”) for attempted resolution. In the event such Executives are unable to resolve such Dispute within 30 days of such Dispute being referred to them, then, either Party may, at its sole discretion, seek resolution of such matter in accordance with Section 10.2.

10.2 Submission to Court for Resolution. Subject to Section 10.1, the Parties hereby irrevocably and unconditionally consent to the exclusive jurisdiction of the courts located in the Southern District of California for any action, suit or proceeding (other than appeals therefrom) arising out of or relating to this Agreement, and agree not to commence any action, suit or proceeding (other than appeals therefrom) related thereto except in such courts. The Parties further hereby irrevocably and unconditionally waive any objection to the laying of venue of any action, suit or proceeding (other than appeals therefrom) arising out of or relating to this Agreement in the courts of California, and hereby further irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. Each Party further agrees that service of any process, summons, notice or document by registered mail to its address set forth in Section 11.9 shall be effective service of process for any action, suit or proceeding brought against it under this Agreement in any such court. Notwithstanding anything to the contrary in this Section 10.2, each Party shall have the right to institute judicial proceedings against the other Party or anyone acting by, through or under such other Party, in any court of competent jurisdiction, in order to enforce the instituting Party’s rights hereunder through reformation of contract, specific performance, injunction or similar equitable relief.

25.

10.3 Court Actions. Nothing contained in this Agreement shall deny either party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing discussions between the parties or any ongoing arbitration proceeding. In addition, either party may bring an action in any court of competent jurisdiction to resolve Disputes pertaining to the validity, construction, scope, enforceability, infringement or other violations of Patent Rights or other intellectual property rights, and no such claim shall be subject to arbitration pursuant to Section 10.2.

11.

MISCELLANEOUS.

11.1 Rights Upon Bankruptcy. 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 US (collectively, the “Bankruptcy Laws”), licenses of rights to be “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 in such Bankruptcy Laws, such party (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) shall perform all of the obligations provided in this Agreement 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 in the Bankruptcy Laws and the other party elects to retain its rights hereunder as provided in 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 other party copies of all Information necessary for such other party to prosecute, maintain and enjoy its rights under the terms of this Agreement promptly upon such other party’s written request therefor. 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.

11.2 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California, USA, excluding its conflicts of laws principles.

11.3 Entire Agreement; Amendments. This Agreement (including the Exhibits hereto), is both a final expression of the parties’ agreement and a complete and exclusive statement with respect to all of its terms. This Agreement supersedes all prior and contemporaneous agreements and communications, whether oral, written or otherwise, concerning any and all matters contained herein between the Company and BioAtla. The Exhibits to this Agreement are incorporated herein by reference and shall be deemed a part of this Agreement. This Agreement may be amended, or any term hereof modified, only by a written instrument duly executed by authorized representatives of both parties hereto.

11.4 Non-Waiver. The failure of a party to insist upon strict performance of any provision of this Agreement or to exercise any right arising out of this Agreement shall neither impair that provision or right nor constitute a waiver of that provision or right, in whole or in part, in that instance or in any other instance. Any waiver by a party of a particular provision or right shall be in writing, shall be as to a particular matter and, if applicable, for a particular period of time and shall be signed by such party.

26.

11.5 Assignment. Except as expressly provided hereunder, neither this Agreement nor any rights or obligations hereunder may be assigned or otherwise transferred by either party without the prior written consent of the other party; it being understood and agreed that, either Party may assign this Agreement to an Affiliate, provided that the assigning party shall remain liable and responsible to the non-assigning party hereto for the performance and observance of all such duties and obligations by such Affiliate.

The rights and obligations of the parties under this Agreement shall be binding upon and inure to the benefit of the successors and permitted assigns of the parties, and the name of a party appearing herein will be deemed to include the name of such party’s successors and permitted assigns to the extent necessary to carry out the intent of this section. Any assignment not in accordance with this Agreement shall be void.

11.6 Change of Control. Notwithstanding anything to the contrary in this Agreement, with respect to any intellectual property rights controlled by the acquiring party or its Affiliates (if other than one of the Parties to this Agreement or any Affiliate of a Party immediately before such Change of Control) involved in any Change of Control of either Party, such intellectual property rights shall not be included in the technology and intellectual property rights licensed to the other Party hereunder to the extent held by such acquirer or its Affiliates (other than the relevant Party to this Agreement or any Affiliate of a Party immediately before such Change of Control) prior to such transaction, or to the extent such technology is developed outside the scope of activities conducted with respect to any Product. The BioAtla Licensed Technology and the Company Licensed Technology shall exclude any intellectual property owned or controlled by a permitted assignee or successor and not developed in connection with any Product developed, manufactured or commercialized pursuant to this Agreement.

11.7 Force Majeure. Each party shall be excused from liability for the failure or delay in performance of any obligation under this Agreement by reason of any event beyond such party’s reasonable control, including but not limited to acts of God, fire, flood, explosion, earthquake, or other natural forces, war, civil unrest, acts of terrorism, accident, destruction or other casualty, any lack or failure of transportation facilities, any lack or failure of supply of raw materials, any strike or labor disturbance, or any other event similar to those enumerated above. Such excuse from liability shall be effective only to the extent and duration of the event(s) causing the failure or delay in performance and provided that the party has not caused such event(s) to occur. The affected party shall notify the other party of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake all reasonable efforts necessary to cure such force majeure circumstances.

11.8 Severability. If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the parties. The parties shall in such an instance use their best efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implement the purposes of this Agreement.

27.

Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Exclusive License Agreement by and between Inversagen and BioAtla effective as of March 15, 2019 (the “Agreement”).

Background

The parties desire to amend the Agreement as described more fully herein to provide BioAtla with an option as provided below.

Terms

NOW, THEREFORE, in consideration of the mutual covenants contained herein, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the Parties hereto, intending to be legally bound, hereby agree as follows:

1. Amendment to Agreement. New Section 2.10 is hereby added as an amendment to the Agreement: “Option Grant. Subject to this Section 2.10, the Company hereby grants to BioAtla the exclusive option (the “Option”), exercisable at any time during the period commencing on July 7, 2020 and ending on July 7, 2030 (the “Option Term”), to acquire the sole and exclusive rights solely to develop, make, have made, use, sell, have sold, offer for sale and import the [***] Product in the Field in the Territory (other than the People’s Republic of China, Hong Kong, Taiwan and Macau) (such sole and exclusive rights, the “Rights”) with all provisions of the Agreement applying, mutatis mutandis, provided that (a) all references to the Company and BioAtla shall be switched and (b) all references to Product shall be switched so as to refer to the [***] Product, and (c) the royalty rate referred to in Section 4.2 shall be [***].

The Company hereby represents and

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

warrants to BioAtla that, as of July 7, 2020, the Company has not directly or indirectly licensed, assigned or otherwise transferred any of the Rights to any person (other than to BioAtla pursuant to this Section 2.10). The Company hereby covenants and agrees with BioAtla that, during the Option Term, the Company shall not directly or indirectly license, assign or otherwise transfer any of the Rights to any person (other than to BioAtla pursuant to this Section 2.10).”

2. Miscellaneous. The Parties hereby confirm and agree that, except as amended hereby, the Agreement remains in full force and effect and is a binding obligation of the Parties hereto. This Amendment may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

This Amendment is executed by the authorized representatives of the parties as of the date first written above.
