4.6 Royalties.

4.6.1. Royalties for Licensed Products. Licensee shall pay Inhibrx royalties in Dollars at the rates set forth in the table below on a Quarterly basis with respect to Net Sales of Licensed Products during such Quarter, calculated on a Licensed Product-by-Licensed Product and country-by-country basis (provided that the applicable royalty rate shall be based on aggregate Net Sales of the Licensed Product in all countries where the Royalty Term has not expired), as set forth in this Section 4.6.



Net Sales of Licensed Product during each Year	Royalty Rate
Portion of aggregate Net Sales during such Year less than $[***]	[***]%
Portion of aggregate Net Sales during such Year that is equal to or greater than $[*] but is less than or equal to $[*]	[***]%
Portion of aggregate Net Sales during such Year that is greater than $[***]	[***]%

Notwithstanding the foregoing, on a country-by-country basis, if the only Valid Claim that Covers such Licensed Product is in a Binder Improvement Patent owned solely by Licensee, and a corresponding Binder Improvement Patent owned solely by Licensee with a Valid Claim that Covers such Licensed Product has been granted by the European Patent Office, then the foregoing royalty rates applicable for such country shall be reduced by [***] percent ([***]%) for the remainder of the Royalty Term.

4.6.2. Royalty Term. Licensee’s royalty payment obligation shall commence, on a Licensed Product-by-Licensed Product and country-by-country basis, on the First Commercial Sale of such Licensed Product in such country, and shall expire on the later of: (i) the date on which there is no longer a Valid Claim that Covers such Licensed Product; (ii) the date on which any applicable regulatory, pediatric, orphan drug or data exclusivity, which provides Licensee with the exclusive right to market the Licensed Product in the relevant country, expires; or (iii) twelve (12) years after the First Commercial Sale of such Licensed Product in such country (such period, the “Royalty Term”). In each country in which no Valid Claim that Covers such Licensed Product (i.e., such Licensed Product is royalty-bearing only because of clauses (ii) or (iii) above), then the applicable royalty rate for such country as provided in Section 4.6.1 shall be reduced by [***] percent ([***]%) for the remainder of the Royalty Term.

4.6.3. Third Party Obligations. To the extent that Licensee (A) deems Third Party intellectual property is necessary or useful to Develop or Commercialize a Licensed Product (other than with respect to any Other Component in the case of a Combination Product or Delivery System), or (B) is subject to a final court or other binding order or ruling that the exploitation of any Licensed Product by or on behalf of Licensee, its Affiliates or its sublicensees under this Agreement infringes, misappropriates or otherwise violates any Third Party rights in such Know-How or Patents (each of (A) and (B), a “Third Party Obligation”), then, subject to Section 4.6.6 (Cumulative Adjustments), Licensee shall have the right on a country-by-country basis to deduct from the royalty payments payable to Inhibrx under Section 4.6.1 in a given Quarter, [***] percent ([***]%) of the payments owed by Licensee to such Third Party pursuant to any Third Party Obligations in or prior to such Quarter; provided, however, that such deductions shall not reduce the royalty payments otherwise due to Inhibrx by more than [***] percent ([***]%) of the amount that would have been otherwise due. Licensee may carry forward any deductions permitted in accordance with this Section 4.6.3 [***].

4.6.4. Only One Royalty. Only one (1) royalty shall be due with respect to the same unit of Licensed Product. Only one (1) royalty shall be due hereunder on the sale of a Licensed Product even if more than one (1) Valid Claim Covers such Licensed Product.

4.6.5. Biosimilar Entry. Subject to Section 4.6.6 (Cumulative Adjustments), on a Licensed Product-by-Licensed Product and country-by-country basis, if during any portion of the Royalty Term for a given Licensed Product in a given country in the Territory, (i) there is no longer a Valid Claim that covers the composition of matter of such Licensed Product (or any active ingredient thereof) in such country, (ii) there is Biosimilar Competition with respect to such Licensed Product in such country for a period of [***] ([***]) [***] and (iii) there is at least a [***]% decrease in revenue for Licensee on sales of such Licensed Product to Third Party purchasers in the calendar quarter in such country as compared to the average revenue received by Licensee on sales of such Licensed Product in such country during the calendar quarter immediately preceding the entry of the first Biosimilar Product, then the royalty rate that would otherwise be owed and payable under Section 4.6.1, in each case, with respect to Net Sales of such Licensed Product in such country shall be reduced by [***] percent ([***]%) for the remainder of the Royalty Term for such Licensed Product in such country. “Biosimilar Competition” shall be deemed to exist in a particular country with respect to a particular Licensed Product in a given calendar quarter if in such country from and after the first calendar quarter during which one or more Biosimilar Products (other than one or more Authorized Biosimilar Products)) in the aggregate account(s) for more than [***] percent ([***]%) of the sum of (i) the aggregate unit sales of such Licensed Product by Licensee or its Affiliates or by a sublicensee in such country, and (ii) the aggregate unit sales of such Biosimilar Product(s) in such country, as measured by a data source as reasonably agreed upon by Inhibrx and Licensee no later than the First Commercial Sale of the applicable Licensed Product. If no data is commercially available for a country, then [***]. “Authorized Biosimilar Product” means a Biosimilar Product sold by Licensee or any of its Affiliates or sublicensee or other Third Party under a license granted by Licensee or its Affiliate, or distributed under a Regulatory Approval held by Licensee or any of its Affiliates.

4.6.6. Cumulative Adjustments. Notwithstanding the foregoing, in no event will the operation of reductions under Section 4.6.3 (Third Party Obligations) or 4.6.5 (Biosimilar Entry), individually or in combination, reduce the royalties paid to Inhibrx with respect to any Licensed Product in any country in any

calendar quarter to less than [***]% of the royalties that would otherwise have been due pursuant to Section 4.6.1 (Royalties for Licensed Products) (as may be adjusted for lack of a Valid Claim under Section 4.6.2 (Royalty Term). Except as set forth in Section 4.6.3 (Third Party Obligations), Licensee may not carry forward any such reductions that are not applied as a result of the foregoing floor.

4.6.7. Reports; Payment of Royalty. During the Term, and following the First Commercial Sale of any Licensed Product, Licensee shall within [***] ([***]) [***] after the end of each Quarter furnish to Inhibrx a written report for such Quarter showing, on a Licensed Product-by-Licensed Product basis, the gross sales of such Licensed Product(s) during such Quarter, all deductions and adjustments in the calculation of such Net Sales (reported in the aggregate), and the Net Sales and royalties due during such Quarter. Inhibrx shall have a period of [***] ([***]) [***] to review such report and to provide any comments to Licensee in writing, which Licensee shall consider in good faith; provided, for avoidance of doubt, that such review by Inhibrx shall not be deemed to be an acceptance by Inhibrx of the accuracy of any such report or related payment. Licensee shall pay all royalties due under this Agreement with respect to a Quarter within [***] ([***]) [***] after the end of such review period.

4.7 Audits.

(a) Upon [***] ([***]) [***] prior written request of Inhibrx and not more than [***] in each Year, Licensee shall permit an independent certified public accounting firm of nationally recognized standing selected by Inhibrx, at Inhibrx’s expense, to have access during normal business hours to such of the records of Licensee as may be reasonably necessary to verify the accuracy of royalty reports hereunder for any Year ending not more than [***] ([***]) [***] prior to the date of such request; provided that if Inhibrx has timely commenced an audit with respect to any earlier time period and such audit shall be pending or its results disputed, Inhibrx shall have continued access to the records of such earlier time period. The accounting firm shall disclose to Inhibrx whether the royalty reports are correct or incorrect, the amount of any royalty discrepancy, as well as the calculation of the foregoing.

(b) If such accounting firm correctly identifies an underpayment made by Licensee during such period, Licensee shall pay Inhibrx one hundred percent (100%) of the amount of such underpayment (along with interest in accordance with Section 4.7.2) within [***] ([***]) [***] of the date Inhibrx delivers to Licensee such accounting firm’s written report so concluding, or as otherwise agreed upon in writing by the Parties. Inhibrx shall pay the fees charged by such accounting firm; provided, however, if such audit uncovers an underpayment by Licensee that exceeds [***] ([***]) of the total payment due for the period under audit, then Licensee shall pay the fees of such accounting firm whether previously paid by Inhibrx or then due. In the event that the accounting firm uncovers an overpayment by Licensee, then Licensee shall credit one hundred percent (100%) of the amount of such overpayment against any payments owing in the Quarter following the Quarter in which such audit was completed, and future payments hereunder to be adjusted accordingly on a carry-forward basis until such overpayment amount has been fully credited against amounts owing to Inhibrx, or if no further amounts are owing to Inhibrx, Inhibrx shall refund such overpayment amount to Licensee within [***] ([***]) [***].

(c) Licensee shall include in each sublicense granted by it pursuant to this Agreement a provision requiring the sublicensee to make reports to Licensee, to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records by Inhibrx’s independent accountant to the same extent required of Licensee under this Agreement.

(d) Inhibrx shall treat all financial information subject to review under this Section 4.7 or under any sublicense agreement in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with Licensee or its Affiliates obligating it to retain all such information in confidence pursuant to such confidentiality agreement.

4.7.2. Payment Method; Late Payment. Licensee shall pay all amounts due hereunder in United States Dollars by wire transfer of immediately available funds to the bank account Inhibrx designates in writing from time to time. Payments based on Net Sales in currencies other than United States Dollars shall be converted by

Licensee into United States Dollars using reasonable procedures consistent with Licensee’s global practices, with the conversion ratio based on the date of payment from Licensee to Inhibrx. If any payment is not made when due, simple interest shall thereafter accrue on the sum due until the date of payment at the per annum rate of [***] percent ([***]%) or, if lower, the maximum rate permitted by applicable law.

4.8 Taxes.

4.8.1. Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the activities of the Parties under this Agreement.

4.8.2. Tax Cooperation. The Parties agree to cooperate with one another in relation to tax withholding or similar obligations in respect of any payments made by a Party to the other Party under this Agreement. Without limiting the generality of the foregoing, a Party receiving payment shall provide the paying Party any tax forms and other information that may be reasonably necessary in order for the paying Party to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty. The Party receiving payment shall provide any such tax forms to the paying Party at least [***] ([***]) [***] prior to the due date for any payment for which the Party receiving payment desires that the paying Party apply a reduced withholding rate. Each Party shall provide the other with reasonable cooperation to enable the recovery, as permitted by applicable Law, of withholding taxes, value added taxes, or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of the Party bearing such withholding tax or value added tax.

4.8.3. Payment of Tax. To the extent a Party is required by applicable Law to deduct and withhold taxes on any payment to the other Party, the paying Party shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to the other Party an official tax certificate or other evidence of such withholding sufficient to enable such other Party to claim such payment of taxes.

4.8.4. Treatment of Certain Withholding Tax. If a Party is required to deduct and withhold taxes on any payment to the other Party and such withholding obligation arises as a result of any action by the paying Party that has the effect of modifying the tax treatment of the Parties (including any assignment or sublicense, or any failure on the part of the paying Party to comply with applicable Law or filing or record retention requirements) (a “Withholding Tax Action”), then the sum payable by the paying Party (in respect of which such deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that the other Party actually receives, as appropriate, a sum equal to the sum that it would have received had no such Withholding Tax Action occurred; provided, however, that no such increase shall apply to the extent such increase would have resulted (i) from a change in applicable Law increasing the applicable withholding tax rate, which change occurs after the Effective Date or (ii) in circumstances where actions or inactions of the Party receiving such payment or any of its Affiliates cause a change in the applicable withholding tax rate, for example, the failure of the Party receiving such payment to timely provide to the paying Party the appropriate treaty forms and the certificate of residence necessary for the paying Party to withhold at a more favorable rate.

4.9 Accounting Cooperation. The Parties shall cooperate in good faith to provide information to enable both Parties to accurately account for this Agreement under U.S. generally accepted accounting principles, or other internationally recognized accounting principles, consistently applied.

Is developed by the Receiving Party independently of Confidential Information received from the Disclosing Party and without the aid, application or use of the Disclosing Party’s Confidential Information, and such independent development can be properly documented by the Receiving Party. Any combination of features or disclosures shall not be deemed to fall within the foregoing exclusions merely because individual features are published or available to the general public or in the rightful possession of the Receiving Party unless the combination itself and principle of operation are published or available to the general public or in the rightful possession of the Receiving Party.

5.4 Permitted Disclosure. Nothing in this Section 5 shall restrict the Receiving Party from disclosing Confidential Information of the Disclosing Party to the extent that such disclosure:

5.4.1.

6. Intellectual Property.

6.1 Binder Improvement Patents.

6.1.1. Ownership of Binder Improvements shall follow inventorship as determined in accordance with the patent laws of the United States. Neither Party will Prosecute a Patent claiming a Binder Improvement without the other Party’s prior written consent. The Parties shall agree upon a strategy to Prosecute each Patent claiming a Binder Improvement with the goal of securing and maintaining the broadest reasonable protection available for such Binder Improvements in countries where it is commercially reasonable to do so [***].

6.1.2. Licensee hereby grants to Inhibrx an exclusive, perpetual, irrevocable, sublicensable, worldwide, fully-paid up license to Licensee’s interest in any Binder Improvements for uses outside of the Field. Inhibrx will compensate Licensee for any product developed either directly or indirectly by Inhibrx that includes a Binder Improvement by paying to Licensee the milestones set forth Section 4.4 and the royalties set forth in Section 4.6 in each case, mutatis mutandis.

6.2 Filing, Prosecution and Maintenance of Patents.

6.2.1. Inhibrx shall have the right, but not the obligation, to Prosecute Binder Patents at its own cost. Notwithstanding the foregoing, at Licensee’s request during the Program Term or after the exercise of the

Option during the Term, to the extent a Binder Patent existing as of the Effective Date has a claim directed to a Licensed Product or the use of a Binder in the Field, Inhibrx shall use reasonable efforts, to the extent practical to do so, file divisional and/or continuation Patents consisting solely of claims to the Licensed Product or the use of a Binder in the Field, which Patent will be a Product-Specific Patent. During the Program Term or after the exercise of the Option during the Term:

(a) Inhibrx shall copy Licensee on all correspondence from and to any patent office relating to Binder Patents that include claims to a Licensed Product or to use of a Binder in the Field in a timely manner, and Inhibrx shall provide Licensee with drafts of all filings and correspondence relating to the Prosecution of Binder Patents that include disclosure or claims to Licensed Products or to use of a Binder in the Field in reasonably adequate time before filing or submission of such materials, for Licensee’s review and comment. For avoidance of doubt, Inhibrx shall provide draft filings of Binder Patents that include disclosure or claims to Licensed Products or to use of a Binder in the Field before the Binder Patents are filed. Inhibrx will take into good faith consideration Licensee’s comments prior to submitting such filings and correspondences to the extent such comments are timely provided and it is practicable to do so. If there is a disagreement between the Parties with respect to the Prosecution (other than the initial preparation and filing) of claims of a Binder Patent to a Licensed Product or to the use of a Binder in the Field, then Inhibrx shall have the right to make the final decision. If there is a disagreement between the Parties with respect to the initial preparation and filing of a Binder Patent containing claims to a Licensed Product or to the use of a Binder in the Field, then Parties will discuss in good faith how to remedy the disagreement. Inhibrx shall provide Licensee an annual report summarizing the status of the Prosecution of the Binder Patents that include claims to use of a Binder in the Field.

(b) Inhibrx shall notify Licensee of any decision not to Prosecute, including a decision not to continue to pay the expenses of prosecution or maintenance of, any Binder Patents, including divisional and continuation Patents. Inhibrx shall provide such notice at least [***] ([***]) [***] prior to any filing or payment due date, or any other due date that requires action, in connection with such Binder Patent. In such event, Licensee shall, upon written notice to Inhibrx, have the sole right, but not the obligation, to file for, or continue prosecution or maintenance of, such Binder Patent, at Licensee’s expense. Inhibrx shall cooperate with Licensee in its preparation, filing, prosecution and maintenance of such Binder Patents, including by providing Licensee with data and other information (but for avoidance of doubt, Inhibrx shall not be obligated to generate any additional data) as appropriate and executing all necessary affidavits, assignments and other paperwork.

6.2.2. Subject to Section 6.2.1, Licensee shall have the first right, but not the obligation, to Prosecute Product-Specific Patents in the Territory at its own cost and expense. Notwithstanding the foregoing, (i) if Inhibrx has not filed a Binder Patent with claims specifically covering such Binder then Inhibrx will coordinate filing of the Binder Patent with Licensee’s filing of a Product-Specific Patent with respect to the Binder; (ii) Licensee may file a Product-Specific Patent with respect to a Binder if Inhibrx has previously filed a Binder Patent with claims specifically covering such Binder, if approved in writing by Inhibrx on a case-by-case basis, and (ii) Licensee shall use Commercially Reasonable Efforts to Prosecute each Product-Specific Patent with the goal of securing and maintaining the broadest reasonable protection available for such Product-Specific Patents in countries where it is commercially reasonable to do so (including, at a minimum, in the United States, China, Japan, the United Kingdom, Germany, Italy, Spain and France).

(a) At Licensee’s expense, Inhibrx shall cooperate with Licensee in its Prosecution of any Product-Specific Patent, including by providing Licensee with data and other information as appropriate (but for avoidance of doubt, Inhibrx shall not be obligated to generate any additional data) and executing all necessary affidavits, assignments and other paperwork. Within [***] ([***]) [***] after the Effective Date, Inhibrx shall provide to Licensee any copies of patent filings and correspondence between Inhibrx and patent authorities within the Territory regarding the Binder Patents existing as of the Effective Date.

(b) Licensee shall copy Inhibrx on all correspondence from and to any patent office relating to the Product-Specific Patents in a timely manner, and Licensee shall provide Inhibrx with drafts of all filings and correspondence relating to the Prosecution of Product-Specific Patents in reasonably adequate time

before filing or submission of such materials, for Inhibrx’s review and comment. Licensee will take into good faith consideration Inhibrx’s comments prior to submitting such filings and correspondences to the extent such comments are timely provided and it is practicable to do so. If there is a disagreement between the Parties with respect to the Prosecution (other than the initial preparation and filing) of Product-Specific Patents, then Licensee shall have the right to make the final decision. Licensee shall provide Inhibrx an annual report summarizing the status of the Prosecution of the Product-Specific Patents.

(c) Licensee shall notify Inhibrx of any decision not to Prosecute, including a decision not to continue to pay the expenses of prosecution or maintenance of, any Product-Specific Patents, including divisional and continuation Patents. Licensee shall provide such notice at least [***] ([***]) [***] prior to any filing or payment due date, or any other due date that requires action, in connection with such Product-Specific Patent. In such event, Inhibrx shall, upon written notice to Licensee, have the sole right, but not the obligation, to file for, or continue prosecution or maintenance of, such Product-Specific Patent, at Inhibrx’s expense. Licensee shall cooperate with Inhibrx in its preparation, filing, prosecution and maintenance of such Product-Specific Patents, including by providing Inhibrx with data and other information (but for avoidance of doubt, Licensee shall not be obligated to generate any additional data) as appropriate and executing all necessary affidavits, assignments and other paperwork.

6.2.3. Except as otherwise specifically provided in this Section 6.2, as between the Parties, each Party shall have the sole right to control the preparation, prosecution and maintenance of Patents claiming inventions owned or Controlled by such Party, at its sole expense.

6.3 Enforcement and Defense.

6.3.1. Infringement. Each Party shall give the other Party written notice of any actual or threatened infringement or misappropriation of any Binder Patents, Binder Improvement Patents, or Product-Specific Patents, by an unlicensed Third Party through the making, having made, research, development, using, selling, offering for sale, exporting or importing of any product that is within the scope of the license granted to Licensee under Section 3.5.1 (a “Product Infringement”), within [***] ([***]) [***] after such Party has knowledge of such Product Infringement. Licensee and Inhibrx shall thereafter consult and cooperate to determine a course of action, including the commencement of legal action by either or both Licensee and Inhibrx, to terminate any such Product Infringement.

6.3.2. Enforcement.

(a) Licensee, upon notice to Inhibrx, shall have the first right to initiate and prosecute such legal action (“Product Infringement Action”) at its expense, or to control the defense of any declaratory judgment action relating to such Product Infringement; provided that Licensee shall not enter into any settlement or compromise that would materially diminish or adversely affect the scope, exclusivity or duration of any Licensed IP or Inhibrx’s rights under this Agreement, without Inhibrx’s prior written consent, which it may withhold in its sole discretion. Notwithstanding the foregoing, Licensee shall have the right to enforce a Binder Patent only: (i) if a Licensed Product Covered by such Binder Patent is at such time diligently being commercialized by a Selling Party in such country, and (ii) there is no Product-Specific Patent or Binder Improvement Patent in such country with a Valid Claim that Covers such Licensed Product.

(b) If Licensee elects not to, or does not, initiate and prosecute a Product Infringement Action in a timely manner, then Inhibrx shall have the right to do so in accordance with Section 6.3.2 of this Agreement. If Inhibrx elects to initiate and prosecute a Product Infringement Action as a result of Licensee not doing so in a timely manner, then Inhibrx shall: (i) notify Licensee in writing at least [***] ([***]) [***] prior to initiating such action (“Inhibrx Product Infringement Initiation Notice”); and (ii) bear the costs of any such Product Infringement Action to terminate such Product Infringement, including the costs of any legal action commenced or the defense of any declaratory judgment, except that Inhibrx shall not be responsible for any costs

incurred by Licensee unless such costs were incurred at Inhibrx’s written request. Inhibrx shall have the right to join Licensee as a party to such action if Licensee is a necessary party to such action.

(c) Notwithstanding Inhibrx’s right to initiate a Product Infringement Action under Section 6.3.2(b), Licensee shall have the right to prohibit Inhibrx from exercising its right to initiate such Product Infringement Action (“License Product Infringement Restriction Right”) by providing Inhibrx with written notice of Licensee’s reasonable, strategic rationale for doing so no later than [***] ([***]) [***] after delivery of the corresponding Inhibrx Product Infringement Initiation Notice and Inhibrx shall not initiate or proceed with the Product Infringement Action described in the corresponding Inhibrx Product Infringement Initiation Notice. If Licensee does not exercise its Licensee Product Infringement Restriction Right prior to the date that is [***] ([***]) [***] after delivery of the corresponding Inhibrx Product Infringement Initiation Notice, then: (x) Licensee shall have no further right to prohibit Inhibrx from initiating with the Product Infringement Action described in such Inhibrx Product Infringement Initiation Notice; and (y) Inhibrx shall have the right, exercisable in Inhibrx’s sole discretion, to initiate, proceed with and prosecute such Product Infringement Action in accordance with Section 6.3.2(b).

6.3.3. Cooperation. In connection with any action under this Section 6.3, Licensee and Inhibrx shall, at Licensee’s cost, reasonably cooperate and will provide each other with any information or assistance that either may reasonably request. Each Party shall keep the other informed of developments in any such action or proceeding, including, to the extent permissible by applicable Law, consultation on and approval of any settlement, the status of any settlement negotiations and the terms of any offer related thereto. Each Party shall have the right to be represented by counsel of its own choice at its own expense for any action set forth in this Section 6.3.

6.3.4. Any recovery obtained by either or both Licensee and Inhibrx in connection with or as a result of any action contemplated by this Section 6.3, whether by settlement or otherwise, shall be shared in order as follows:

(a) The Party that initiated and prosecuted the action shall recoup all of its costs and expenses incurred in connection with the action;

(b) The other Party shall then, to the extent possible, recover its costs and expenses incurred in connection with the action; and

(c) The Party initiating such action shall retain any remainder provided that if Licensee is the initiating Party, such remainder shall be shared [***] percent ([***]%) to Licensee and [***] percent ([***]%) to Inhibrx.

8.4 Effect of Expiration or Termination Generally; Survival. Expiration or termination of this Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or termination. Any expiration or termination of this Agreement shall be without prejudice to the rights of either Party against the other accrued or accruing under this Agreement prior to expiration or termination, including the obligation to pay royalties for Licensed Product(s) sold prior to such expiration or termination. Termination of this Agreement is without prejudice to any of the other rights and remedies conferred on the non-breaching Party by this Agreement or under law or equity, including the right to pursue damages or equitable remedies and the right to pursue payment of any amounts owed by the non-breaching Party to the breaching Party after termination by the non-breaching Party pursuant to this Section 8.

Licensee shall indemnify, defend, and hold Inhibrx, its Affiliates and its and their respective agents, employees, officers and directors (each a “Inhibrx Indemnitee”) harmless from and against any and all Third Party claims, suits, actions, demands, judgments, liabilities, expenses, or losses, including reasonable legal expenses and attorneys’ fees (collectively, “Inhibrx Losses”) to which any Inhibrx

Indemnitee may become subject to the extent such Inhibrx Losses are directly or indirectly caused by or otherwise arise out of or in connection with: (a) the performance by Licensee (or its Affiliates, sublicensees or subcontractors) of Licensee’s obligations under this Agreement; (b) the practice by Licensee, its Affiliates or its sublicensees of any license or sublicense granted to Licensee hereunder, through the manufacture, research, development, use, sale, offer for sale, exportation, or importation of a Licensed Product or otherwise; (c) the manufacture, use, handling, storage, importation, exportation, sale, or other disposition by Licensee, its Affiliates, sublicensees, subcontractors or distributors of Licensed Product(s); (d) the use by a Third Party of any Licensed Product sold or otherwise provided by Licensee, its Affiliates, sublicensees, subcontractors or distributors; (e) a breach by Licensee or its Affiliates of any covenant, representation, warranty or other agreement made by Licensee in this Agreement; or (f) the gross negligence or willful misconduct of (1) Licensee or its Affiliates or (2) Licensee’s sublicensees, subcontractors, distributors or agents acting in connection with the matters that are subject of this Agreement; except, in each case, to the extent such Inhibrx Losses result from: (i) the breach by Inhibrx, its Affiliates, sublicensees or subcontractors of any covenant, representation, warranty or other agreement made by Inhibrx in this Agreement; or (ii) the negligence or willful misconduct of any Inhibrx Indemnitee.

9.3 Notice of Indemnification Obligation and Defense. As used in this Section, the term “Losses” means, as applicable, any and all Inhibrx Losses or Licensee Losses, and “Indemnitees” means, as applicable, any and all Inhibrx Indemnitees or Licensee Indemnitees. Any Party entitled to indemnification under Section 9.1 or 9.2 shall promptly give notice to the indemnifying Party of any actual or potential Losses of which it becomes aware that may be subject to indemnification hereunder, but the failure or delay to so notify the indemnifying Party shall not relieve the indemnifying Party from any liability under Section 9.1 or 9.2 except to the extent that the indemnifying Party’s ability to defend against such Losses was actually prejudiced as a result of such failure or delay. The indemnifying Party shall have the right to assume and control the defense of such Losses (at its own expense) with outside counsel of its choice and reasonably satisfactory to the indemnified Party; provided, however, that the indemnified Party shall have the right to retain and be represented by its own counsel (at its own expense) in connection therewith. The indemnified Party shall, upon request, cooperate with the indemnifying Party and its legal representatives in connection with the investigation and defense of such Losses, including by providing or otherwise making available information in its possession with respect thereto. Neither Party shall settle or otherwise resolve any claim, suit, action, or demand related to any Losses without the prior written consent of the other Party, if such settlement or other resolution would (a) result in the admission of any liability or fault on behalf of the other Party or its Indemnitees, (b) result in or impose any payment obligations upon the other Party or its Indemnitees, (c) or subject the other Party to an injunction or otherwise limit the other Party’s ability to take any actions or refrain from taking any actions under this Agreement.

9.4 LIMITATION OF LIABILITY. EXCEPT FOR LIABILITIES ARISING UNDER SECTIONS 9.1 AND 9.2, IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY SPECIAL, PUNITIVE, INDIRECT, INCIDENTAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES (INCLUDING ANY CLAIMS FOR LOST PROFITS, SALES, REVENUES OR OPPORTUNITIES) ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT (OR THE EXERCISE OF ITS RIGHTS HEREUNDER) UNDER ANY THEORY OF LIABILITY, AND REGARDLESS OF ANY NOTICE OR KNOWLEDGE OF THE POSSIBILITY OF SUCH DAMAGES.

10. General Provisions.

10.1 Assignment. Except as provided in this Section 10.1, neither Party may assign or otherwise transfer this Agreement or any right or obligation hereunder, without the prior written consent of the other Party. Notwithstanding the foregoing, either Party may, without consent of the other Party, assign this Agreement or any of its rights or obligations hereunder in whole or in part to: (i) an Affiliate of such Party; (ii) in connection with the transfer or sale of all or substantially all of its assets, the line of business, or Licensed Product to which this Agreement relates; or (ii) its successor in interest in connection with a Strategic Transaction; provided, however, that in the case of assignment to an Affiliate, the assigning Party shall, notwithstanding such assignment, remain responsible for the performance of such Affiliate under this Agreement. Any attempted assignment not in accordance with this Section 10.1 shall be null and void and of no legal effect. The terms and conditions of this

Agreement shall be binding upon, and shall inure to the benefit of, the Parties and their respected successors and permitted assigns.

10.2 Severability. If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect by a court or other governmental authority of competent jurisdiction, 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 one or both of the Parties. The Parties shall in such an instance cooperate and use good faith efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) which, insofar as practical, implements the purposes of this Agreement.

10.3 Notices. All notices that are required or permitted hereunder shall be in writing and sufficient if (i) delivered personally, (ii) sent by facsimile (and promptly confirmed by personal delivery, registered or certified mail, or internationally recognized express courier (e.g., Federal Express), (iii) sent by internationally recognized express courier or (iv) sent by registered or certified mail, postage prepaid, return receipt requested, addressed as follows:

10.5 Dispute Resolution. The Parties shall negotiate in good faith and use reasonable efforts to amicably settle any dispute, controversy or claim arising from or related to this Agreement or the breach thereof, except for any Excluded Claims (each, a “Dispute”).

10.5.1. If the Parties do not fully settle any Dispute within [***] ([***]) [***] of referring such matter to the executive officers pursuant to Section 10.5, then either Party may submit the Dispute for final

resolution by binding arbitration (an “Arbitration”) administered by JAMS pursuant to its Comprehensive Arbitration Rules and Procedures and in accordance with the Expedited Procedures in those Rules then in effect (the “JAMS Rules”), except as provided in Section 10.5.3 with respect to discovery, and judgment on the Arbitration award may be entered in any court having jurisdiction thereof. The proceedings and decisions of the arbitrators in any Arbitration under this Section 10.5 shall be confidential except as otherwise expressly permitted in this Agreement or required by applicable Law.

10.5.2. Each Arbitration shall be conducted by a panel of three (3) arbitrators, each with substantial experience in the pharmaceutical or biotechnology business selected pursuant to the JAMS Rules. Within [***] ([***]) [***] after initiation of an Arbitration, each Party shall select one (1) person to act as an arbitrator and the two (2) Party-selected arbitrators shall select a third arbitrator within [***] ([***]) [***] of their appointment. If a Party fails to timely select an arbitrator, or if the arbitrators selected by the Parties fail to timely agree upon the third arbitrator, then such arbitrator(s) shall be appointed by JAMS. The place of arbitration shall be New York City, New York and all proceedings and communications shall be in English.

10.5.3. Each Party shall comply with all applicable Laws related to the preservation of evidence as if such dispute were brought in the United States District Court for the Southern District of New York. Notwithstanding the JAMS Rules, each Party shall be entitled to discovery to the same extent provided by the United States Federal Rules of Civil Procedure in effect at the time of such Arbitration, including the right to mandatory disclosures under Rule 26, and the right to take depositions, issue subpoenas (by application to the appropriate court), and obtain documents and written discovery. The arbitrators may sanction a Party that fails to comply with its discovery obligations under this Section 10.5.3, including sanctions provided under Federal Rule of Civil Procedure 37.

10.5.4. The Parties shall maintain the confidential nature of the Arbitration or except as may be necessary in connection with a court application for a preliminary remedy, a judicial challenge to an award or its enforcement, or unless otherwise required by applicable Law or judicial decision.

10.5.5. Either Party may apply to the arbitrators for interim injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved. Either Party also may, without waiving any remedy under this Agreement, seek from any court having jurisdiction any injunctive or provisional relief necessary to protect the rights or property of that Party pending the arbitration award. The arbitrators shall have no authority to award punitive, exemplary or any other type of damages excluded under Section 9.4, and the Parties hereby irrevocably waive any right to seek or recover any such damages. Each Party shall bear an equal share of the arbitrators’ fees and any administrative fees of each Arbitration. The arbitrators’ decision shall be final, not appealable, and legally binding, and judgment may be entered thereon in a court of competent jurisdiction.

10.5.6. Except to the extent necessary to confirm an award or as may be required by applicable Law, neither a Party nor an arbitrator may disclose the existence, content, or results of an Arbitration without the prior written consent of both Parties. In no event shall an Arbitration be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would be barred by applicable New York or federal statute of limitations.

10.5.7. All the obligations of the Parties under this Agreement that are not expressly disputed in the Arbitration shall remain in full force during the Arbitration.

10.5.8. As used in this Section 10.5, the term “Excluded Claim” means a dispute, controversy or claim between the Parties to the extent it concerns (a) the scope, validity, enforceability, inventorship or infringement of Patents; or (b) compliance by the Parties with any Laws governing antitrust, anti-monopoly or competition, whether or not statutory.

10.6 Entire Agreement; Amendments. This Agreement, together with the Exhibits hereto, constitutes the entire understanding of the Parties with respect to the subject matter hereof and supersedes and cancels all

previous express or implied agreements and understandings, negotiations, writings and commitments, either oral or written, in respect to the subject matter hereof. The Exhibits to this Agreement are incorporated herein by reference and are 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.

10.7 Headings. The captions to the several Sections and subsections hereof are not a part of this Agreement, but are merely for convenience to assist in locating and reading the several Sections and subsections hereof.

10.8 Independent Contractors. It is expressly agreed that Inhibrx and Licensee shall be independent contractors and that the relationship between the two (2) Parties shall not constitute a partnership, joint venture or agency, and neither Party will treat the relationship between the Parties as a partnership, joint venture or other entity for any purposes. Neither Inhibrx nor Licensee shall have the authority to make any statements, representations or commitments of any kind on behalf of, or otherwise bind or obligate the other Party, without the prior written consent of such other Party.

10.9 Performance by Affiliates. Each Party may discharge any obligations and exercise any right hereunder through any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed directly against such Party without any obligation to first proceed against such Party’s Affiliate.

10.10 Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as are reasonably necessary to carry out the purposes and intent of this Agreement.

10.11 Waiver. No waiver or release of any obligation under or provision of this Agreement shall be valid or effective unless in writing and signed by the waiving Party. The failure of any Party to insist on the performance of any obligation hereunder shall not be deemed to be a waiver of such obligation. Waiver of any provision hereunder or of any breach of any provision hereof shall not be deemed to be a continuing waiver or a waiver of any other breach of such provision (or any other provision) on such occasion or any succeeding occasion.

10.12 Cumulative Remedies. Unless as specified, no remedy referred to in this Agreement is intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred to in this Agreement or otherwise available under applicable Law.

10.13 Rule of Construction. Each Party has had the opportunity to consult with counsel in connection with the review, drafting and negotiation of this Agreement.

Unless the context of this Agreement otherwise requires, (a) words of any gender include each other gender, (b) words such as “herein”, “hereof”, and “hereunder” refer to this Agreement as a whole and not merely to the particular provision in which such words appear, (c) words using the singular shall include the plural, and vice versa, (d) references to “day” mean calendar days, (e) the words “include,” “includes” and “including” shall be deemed to be followed by the phrase “but not limited to,” “without limitation,” “inter alia” or words of similar import, and (f) the word “or” shall not be deemed to be used in the exclusive sense and shall instead be used in the inclusive sense to mean “or”, unless the context is clear that only one of the options described may apply.

10.15 Counterparts. The Parties may execute this Agreement in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

10.16 No Third Party Beneficiaries. The Parties agree that no provision of this Agreement shall be for the benefit of, or shall be enforceable by any Third Party, including any creditor of either Party.
