No royalty shall accrue under this Section 3.1(a) on sales among Company, its Affiliates, and their respective sublicensees unless Company, its Affiliate, or their sublicensee is the end, user of the Product.

(b) In the event that Company or its Affiliate grants any Third Party a sublicense to market, distribute or otherwise commercialize a Product, in addition to any payments due under Section 3.1(a), Company or its Affiliate shall pay Licensor [***] percent ([***]%) of all consideration, such as but not limited to license fees, development and commercialization milestone consideration, received by Company or its Affiliates in connection with the licensing or sublicensing during the Royalty Term.

(d) For clarity, if there is a transaction to which Company or its Affiliate is a party in which part of the consideration received by Company or its Affiliate is payment for rights to a Product and part of the consideration received by Company or its Affiliate is payment for any other rights or assets of Company or its Affiliate, Company or its Affiliate shall pay Licensor [***] percent ([***]%) of all consideration received.

(e) If consideration received by Company or its Affiliate that is snbject to the payment due to Licensor under clause (a), (b) or (c) of this Section 3.1, as applicable, is in a form other than cash, the payment due to Licensor shall either be the identical consideration received by Company or its Affiliate or, in the sole discretion and at the election of Licensor, in cash equal to the fair market value of such non-cash consideration at the time received by Company or its Affiliate, as reasonably determined in good faith by Licensor. Company shall provide Licensor with as sufficient information as Licensor requires supporting fair market value of the non-cash consideration.

3.2 Calculation and Payment of Royalties. Payments pursuant to Section 3.1 and reports for such payments shall be calculated and reported for each calendar quarter.

3.3 Tax Withholding. Company shall deduct any actual withholding or transfer taxes, which are required by Applicable Laws, from the payments due to Licensor under this Agreement, provided that Company shall use commercially reasonable efforts to minimize any such required taxes to the extent permitted by Applicable Laws. Company will give notice of its intention to begin withholding any such tax in advance and cooperate to use reasonable and legal efforts to reduce such tax on payments made to Licensor hereunder. Any tax required to be deducted under this Agreement will promptly be paid by Company on behalf of Licensor to the appropriate governmental authority. Company shall supply Licensor with proof of payment of such taxes paid on Licensor’s behalf and shall cooperate with Licensor in obtaining a credit or refund of any such taxes. If Company fails to withhold taxes under this provision and taxes are assessed and paid by Company, then Licensor shall reimburse Company for such taxes actually paid (excluding penalties), subject to Licensor’s right to dispute or protest the taxes, and Company shall indemnify and hold harmless Licensor from and against any penalties with respect to such taxes. Notwithstanding anything to the contrary in this Section, Licensor shall not be responsible for paying to Company any penalties attributable to any period between the date the withholding taxes were first due by Company and ending [***] calendar days after written notice by Company to Licensor of such assessment or proposed assessment.

All payments owed under this Agreement shall be made by wire transfer to a bank and account designated in writing by Licensor, unless otherwise specified in writing by Licensor.

3.5 Prohibited Payments. Notwithstanding any other provision of this Agreement, if Company is prevented from paying any royalty or other payment under this Agreement by virtue of the statutes, laws, codes or governmental regulations of the country from which the payment is to be made, then such royalty may be paid by depositing funds in the currency in which accrued to an interest-bearing account in Licensor’s name in a bank acceptable to Licensor in the country whose currency is involved. In the event Licensor cannot arrange to have the blocked currency transferred out of the country within [***] months after deposit, Licensor shall notify Company in writing and Company shall as soon as possible thereafter (and in any event within [***] days) cause such royalties and other payments (plus earnings thereon during the period of deposit) to be paid to Licensor in U.S. Dollars at the rate of exchange reported in The Wall Street Journal, Western Edition on the day the blocked currency was deposited in the bank designated by Licensor.

Upon receipt of the payment, Licensor shall release to Company from the bank in the country in question the blocked currency in accordance with Company’s instructions.

Company, and its Affiliates, as applicable, shall keep complete and accurate records of Net Sales of Products and other consideration received by Company or its Affiliate that is subject to the payment due to Licensor under Sections 3.1(a), (b) or (c), as applicable or the determination of such payments under Sections 3.1(d) or (e), in sufficient detail to permit Licensor to confirm the accuracy of payments due hereunder. Such records shall be open to inspection at any reasonable time during normal business hours not more often than [***] each calendar quarter during the term of this Agreement and for [***] years after the end of the Royalty Term to which such records relate.

Licensor agrees to treat, and to use commercially reasonable efforts to cause such accountant to treat, all such information as confidential and not to use or disclose (except to Licensor and as needed to enforce the terms of this Agreement) any such information for any purpose except to determine compliance with this Agreement. For the avoidance of doubt, Company shall not be obligated to provide Licensor or such accountant with access to any records or information other than that which is necessary to confirm Net Sales, royalty payments and other payments hereunder. Such audits may be exercised upon reasonable prior written notice to Company. Prompt adjustments shall be made by the parties to reflect the results of such audit. The cost of the audits will be borne by Licensor; however, if it is determined by any audit that Licensor has been underpaid in royalties and other payments by more than [***] percent ([***]%) of what was owed to Licensor in any quarter that is the subject of the audit, the cost of the audit will be borne by Company.

3.7 Late Payments. In the event that any payment due under this Agreement is not made when due, the payment will accrue interest from the date due until paid on an annual basis at a rate of [***]% per annum, provided, however, that in no event will such rate exceed the maximum legally permissible annual interest rate. The payment of such interest will not limit Licensor from exercising any other rights it may have as a consequence of the lateness of any payment.

Within [***] days of the occurrence of the Prerequisite Events, and within [***] days of each anniversary of the Effective Date during the term of this Agreement, Company will pay Licensor a non-refundable, non-creditable license maintenance fee in the amount of [***] U.S. dollars ([***]) (the “Maintenance Fee”).

No trade customs, courses of dealing or courses of performance by the parties shall be relevant to modify, supplement or explain any term(s) used in this Agreement. This Agreement may only be amended, modified or supplemented in a writing expressly stated for such purpose and signed by the parties to this Agreement.

10.4 Relationship Between the Parties. The parties’ relationship, as established by this Agreement, is solely that of independent contractors. This Agreement does not create any partnership, joint venture or similar business relationship between the parties. Neither party is a legal representative of the other party, and neither party can assume or create any obligation, representation, warranty or guarantee, express or implied, on behalf of the other party for any purpose whatsoever.

10.5 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.

10.6 Assignment.

(a) 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; provided, however, that either party may assign this Agreement without the other party’s consent:

(i) To its successor in interest in connection with the transfer or sale of all or substantially all of the assets of such party, whether by merger, sale of stock, sale of assets or otherwise, provided that such successor in interest executes a written agreement, in the form reasonably requested by non-transferring party, explicitly confirming agreement with ALL the terms and conditions of this Agreement, and provided further, in the event of such a transaction involving Licensor (whether this Agreement is actually assigned or is assumed by the acquiring party by operation of law (e.g., in the context of a reverse triangular merger)), the intellectual property rights of the acquiring party to such transaction will not be included in the technology licensed hereunder; or

(ii) To an Affiliate, provided that such Affiliate executes a written agreement, in the form reasonably requested by non-transferring party, explicitly confirming agreement with ALL the terms and conditions of this Agreement* and provided further that the assigning party and such Affiliate will be jointly and severally liable and responsible to the non-assigning party hereto for the performance and observance all such duties and obligations by such Affiliate.

(b) Licensor may freely assign its rights to receive payment hereunder in whole or in part and shall have the right to disclose this Agreement in connection therewith.

(c) The rights and obligations of the parties under this Agreement will be binding upon and inure to the benefit of the successors and permitted assigns of the parties, including the parties’ agreement with respect to dispute resolution, governing law, jurisdiction and venue as set forth in Sections 10.1 and 10.2. Any assignment not in accordance with this Agreement will be void.

10.7 Performance by Subparties. Subject to Section 2.2(b), the parties recognize that each may perform some of its obligations under this Agreement through its Affiliates, and its and such Affiliates’ sublicensees and subcontractors (a party’s Affiliates and such party’s and such Affiliates’ sublicensees and subcontractors, each, a “Subparty” and collectively, “Subparties”), provided, however, that (a) Licensor will be jointly and severally liable with Licensor’s Subparties for the performance of Licensor’s Subparties, (b) Company will be jointly and severally liable with Company’s Subparties for the performance of Company’s Subparties, (c) Licensor will be the guarantor of the performance by Licensor’s Subparties, and will cause Licensor’s Subparties to comply with the provisions of this Agreement in connection with such performance, and (d) Company will be the guarantor of the performance by Company’s Subparties, and will cause Company’s Subparties to comply with the provisions of this Agreement in connection with such performance. For clarity, none of the rights of Licensor or Company (each, the “Non-Subcontracting Party”, as applicable) hereunder may be materially diminished or otherwise materially adversely affected as a result of performance by the other party’s Subparties, and Licensor and Company (each, the “Subcontracting Party”, as applicable) will require a written agreement (a “Subcontract”) with their respective Subparties that will perform the Subcontracting Party’s obligations under this Agreement explicitly confirming that such rights are protected, and that will grant third-party beneficiary status to the Non-Subcontracting Party (including the right to enforce the Subcontract and to require payment or other performance directly from the Subparty to the Non-Subcontracting Party). For example, if any Subparties of Company participate in research or other activities in furtherance of the development or commercialization of Products, Company will ensure, and hereby guarantees, that (i) any intellectual property developed by such Subparties will be governed by the provisions of this Agreement (including the obligations in Section 5.2) as if such intellectual property had been developed by Company, (ii) confidential information will be protected by such Subparties as required in this Agreement (including the obligations in Sections 6.1, 6.4 and 6.5) and (iii) the Subparties will covenant to all Company covenants herein (including the covenants in Sections 7.4 and 7.5). Any action or omission by a Subcontracting Party’s Subparties which would, if such action or omission were conducted by the Subcontracting Party, constitute a breach of the Subcontracting Party’s obligations under this Agreement will constitute a breach of such obligation by the Subcontracting Party (unless such obligation were otherwise satisfied by such party or another of its Subparties).

10.8 No Third Party Beneficiaries. This Agreement is neither expressly nor impliedly made for the benefit of any party other than those executing it.

10.9 Severability. In the event any provision of this Agreement is held invalid, illegal or unenforceable in any jurisdiction, to the fullest extent permitted by Applicable Laws, (a) the parties shall negotiate, in good faith and enter into a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the parties and (b) if the rights and obligations of either

party will not be materially and adversely affected, all other provisions of this Agreement shall remain in full force and effect in such jurisdiction. Such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such provision in any other jurisdiction.

10.10 Notices. Any notice or communication required or permitted under this Agreement shall be in writing in the English language. Any notice must be delivered either in person, by any method of mail (postage prepaid) requiring return receipt, or by overnight courier or facsimile confirmed thereafter by any of the foregoing, to the party to be notified at its address(es) given below, or at any address such party has previously designated by prior written notice to the other. Notice shall be deemed sufficiently given for all purposes upon the earlier of: (a) the date of actual receipt; (b) if mailed, [***] calendar days after the date of postmark; (c) if delivered by internationally recognized overnight courier, the next business day the courier regularly makes deliveries (taking into consideration the location of the sending party and the receiving party for international deliveries); or (d) on the day after dispatch if sent by confirmed facsimile.
