Within [***] Business Days after receipt of such updated list (or confirmation that there have been no changes), if such nominated Target is Unavailable, then the Gatekeeper will so notify Seagen, or if such nominated Target is Available, then the Gatekeeper will so notify Seagen and Lava; in each case, the Gatekeeper’s notice will include the identity of the nominated Target.  If a Target nominated by Seagen as a first Additional Target or second Additional Target is Unavailable, then Seagen shall have the right to nominate another Target as a first Additional Target or second Additional Target during the First Target Nomination Period or Second Target Nomination Period, respectively.  If a first Additional Target or second Additional Target nominated by Seagen pursuant to this Section 2.7.3 is Available, then such Target shall be deemed a “First Additional Target” or “Second Additional Target”, as applicable, as of the date such Target Cleared (the date of such Clearance of the First Additional Target, the “First Additional Target Clearance Date”, and the date of such Clearance of the Second Additional Target, the “Second Additional Target Clearance Date”).    For purposes of this Section 2.7, “Cleared” means, with respect to a Target, that the Gatekeeper has notified Seagen and Lava that such Target is Available.  “Clearance” has a corresponding meaning. 
2.7.4Negotiation.  The Parties agree to negotiate in good faith and use commercially reasonable efforts to enter into an agreement, within [***] following the First Additional Target Clearance Date, on the terms set forth in Exhibit A hereto and other commercially reasonable terms (such period, as may be extended only upon mutual written agreement of the Parties, the “Additional Targets License Negotiation Period”, and such agreement, the “Additional Targets License”).  Without limiting the foregoing, the Additional Targets License, if consummated, shall include the grant by Lava to Seagen of an exclusive license to Develop, Manufacture, and Commercialize (a) bispecific or multispecific Antibodies having (i) one (1) variable domain Directed To [***] and (ii) one (1) variable domain Directed To the First Additional Target and (b) so long as a second Additional Target is Cleared during the Second Target Nomination Period, bispecific or multispecific Antibodies having (i) one (1) variable domain Directed To [***] and (ii) one (1) variable domain Directed To such Second Additional Target.
2.7.5Additional Targets Exclusivity.  With respect to each of the First Additional Target and Second Additional Target, during the period beginning on the First Additional Target Clearance Date and Second Additional Target Clearance Date, as applicable, and ending upon the earlier of (a) execution of the Additional Targets License and (b) [***] following the First Additional Target Clearance Date or Second Additional Target Clearance Date, as applicable, Lava shall not, and shall ensure that its Affiliates do not, anywhere in the Territory (i) enter into a term sheet, definitive agreement or other business arrangement with a Third Party, or engage, directly or indirectly, in any negotiations to enter into a term sheet, definitive agreement or other business arrangement with a Third Party, in each case pursuant to which such Third Party has or will have any rights (including through the granting of a license, option or other right) to Develop, Manufacture or Commercialize bispecific or multispecific Antibodies having (A) one (1)

(a)No Valid Claim.  On a Licensed Product-by-Licensed Product and country-by-country basis, if at any time during the Royalty Term for such Licensed Product there is no Valid Claim of [***], then the royalty rates set forth in the applicable table in Section 7.4.1 for such Licensed Product shall be reduced in such country by [***], and shall remain so reduced for the remainder of the Royalty Term for so long as there is no such Valid Claim in such country.
(b)Third Party Payments.  If Seagen or any of its Affiliates or Sublicensees obtains a license or right to [***] from a Third Party that [***], then Seagen shall have the right to credit [***]of [***] actually paid by Seagen, its Affiliate or Sublicensee to such Third Party for such license or right [***] against [***].  Notwithstanding the foregoing, if Seagen is not able to fully credit [***]of such royalties in a given Calendar Quarter, then Seagen shall be entitled to carry forward such right of credit to future Calendar Quarters with respect to such uncredited royalties and continue applying such uncredited amount on a Calendar Quarterly basis thereafter until fully utilized. 
(c)Biosimilar Product.  On a Licensed Product-by-Licensed Product

basis, if during a Calendar Quarter one or more Third Parties is or are selling a Biosimilar Product in a country and Net Sales of the Licensed Product in such country during such Calendar Quarter are less than [***]of the average quarterly Net Sales of the Licensed Product in such country over the [***] Calendar Quarters immediately prior to the Calendar Quarter during which the first such Biosimilar Product was sold in such country (the “Biosimilar Reduction Trigger”), then the royalty rates set forth in the applicable table in Section 7.4.1 for such Licensed Product shall be reduced in such country [***], commencing with such Calendar Quarter in which the Biosimilar Reduction Trigger occurred and thereafter for the remainder of the Royalty Term in such country.
(d)Cumulative Reductions Floor.  In no event will the aggregate amount of royalties due to Lava for a Licensed Product in any given Calendar Quarter be reduced as a result of the reductions set forth in Sections 7.4.2(a), 7.4.2(b) and 7.4.2(c) (cumulatively) by more than [***] of the amount that otherwise would have been due and payable to Lava in such Calendar Quarter for such Licensed Product.   
7.5Lava Buy-Up Option.  
7.5.1Buy-Up Option and Fee.  Seagen hereby grants Lava a one-time option to obtain the royalties set forth in Table #2 of Section 7.4.1 on Net Sales of Licensed Products (the “Buy-Up Option”), on the terms and conditions as set forth in this Section 7.5.  Within [***] days of the Key [***] Clinical Data becoming available for the first Licensed Product, Seagen will provide written notice to Lava of such Key [***] Clinical Data (the “Buy-Up Notice”).  Lava will have [***] days from the date of the Buy-Up Notice to exercise the Buy-Up Option (the “Option Period”).  If Lava desires to exercise the Buy-Up Option, then prior to the end of the Option Period Lava shall: (a) notify Seagen in writing that Lava is exercising the Buy-Up Option; and (b) pay Seagen a one-time fee of [***] within [***] Business Days of the date of such written notification (the “Buy-Up Fee”).  In the event that Lava exercises the Buy-Up Option, then, [***].  The Buy-Up Fee shall be non-refundable except as expressly set forth in Section 13.2. 
7.5.2Effect on Royalties.  If Lava timely exercises the Buy-Up Option, including paying the Buy-Up Fee, then the royalties set forth in Table #2 of Section 7.4.1 shall apply to Net Sales of Licensed Products, and, for clarity, the royalties set forth in Table #1 of Section 7.4.1 shall not apply to such Net Sales.  If Lava (a) notifies Seagen in writing prior to the end of the Option Period that it will not exercise the Buy-Up Option, or (b) does not timely exercise the Buy-Up Option or does not timely pay the Buy-Up Fee, then in each case the royalties set forth in Table #1 of Section 7.4.1 shall apply to Net Sales of Licensed Products, and Lava shall have no further rights to obtain the royalties set forth in Table #2 of Section 7.4.1 with respect to Net Sales of Licensed Products.  
7.5.3Effect on Development Milestone Payments.  In the event Lava has timely exercised the Buy-Up Option and paid the Buy-Up Fee, then (a) the Development Milestone Payments for Development Milestone Events #3 and #4, if achieved, will be reduced [***], (b) the Development Milestone Payment for the first of Development Milestone Events #6-#9, if achieved, will be reduced [***] (for example, if Development Milestone Event #7 is the first such milestone to be achieved, then the Development Milestone Payment #7 would be reduced by [***],

and Seagen would pay the full Development Milestone Payment for Development Milestone Events #6, #8 and #9, if achieved), and (c) if the first of Development Milestone Events #6-#9 to be achieved is Development Milestone Event #6 and if Development Milestone Event #5 was paid to Lava due to achievement of Development Milestone Event #5, then (without limiting clause (b)), Lava shall promptly refund [***] of the amount of Development Milestone Payment #5 to Seagen.
7.6Payment Terms.
7.6.1Development Milestone Payments.  Seagen shall provide Lava with written notice of the achievement of each Development Milestone Event within [***] Business Days thereafter.  Following receipt of such notification, Lava shall invoice Seagen for the amount of the applicable Development Milestone Payment, and Seagen shall make the corresponding Development Milestone Payment within [***] days after receipt of such invoice.
7.6.2Sales Milestone Payments and Royalty Payments.  During the Term, following the First Commercial Sale of a Licensed Product in the Territory, Seagen shall provide Lava with a written report for each Calendar Quarter showing the Net Sales of each Licensed Product in the Territory during the reporting Calendar Quarter and the royalties payable under this Agreement pursuant to Section 7.4.  Each such report shall include, on a Licensed Product-by-Licensed Product and country-by-country basis: (a) the total gross amount invoiced for each Licensed Product sold; (b) the Net Sales of each Licensed Product; (c) the royalties (in Dollars) payable and in total for all Licensed Products; and (d) the manner and basis for any currency conversion in accordance with Section 7.7.  Such reports shall also include notice of any Sales Milestone Event achieved during such Calendar Quarter (if any).  Such reports shall be due no later than [***] days following the end of each Calendar Quarter.  The corresponding Sales Milestone Payment(s) and royalties shown to have accrued by a report provided under this Section 7.6.2 shall be due and payable on the date that such report is due.  
7.7Payment Currency; Exchange Rate; No Offset.  All payments to be made under this Agreement shall be made in USD.  Payments to a Party shall be made by electronic wire transfer of immediately available funds to the account of the other Party, as designated in writing to the paying Party.  If any currency conversion is required in connection with the calculation of amounts payable hereunder, such conversion shall be made using a rate of exchange at the average actual foreign currency exchange rate for the month in which the expense is incurred or sale made according to the exchange rates utilized by the applicable Party in its own internal accounting system, consistently applied.  Except as expressly set forth herein or otherwise agreed to by the Parties, neither Party shall have the right to offset any payment that is owed by the other Party but not paid against any payments owed by such Party, if any, under this Agreement.  
7.8Late Payments.  Any undisputed payments or portions thereof due hereunder that are not paid on the date such payments are due under this Agreement shall bear interest at a rate equal to the lesser of: (a) [***] above the prime rate as published by The Wall Street Journal or any successor thereto on the first day of each Calendar Quarter in which such payments are overdue or (b) the maximum rate permitted by Applicable Law; in each case calculated on the number of

days such payment is delinquent (provided that if the payment is disputed, such interest shall be calculated from the time that the dispute is resolved), compounded monthly.
7.9Payments to [***] and Other Third Parties.  Lava shall be solely responsible for all payments to (a) [***] under the [***] Agreement and (b) any other Third Party that licensed or otherwise granted rights to Lava or any of its Affiliates to any Lava Patents, Lava Know-How, or Lava Materials as of the Effective Date or otherwise as set forth in Section 2.5, in each case ((a) and (b)) with respect to Development, Manufacture, or Commercialization of Licensed Compounds and Licensed Products in the Territory or otherwise with respect to the grant of rights to, or exercise of rights by, Seagen (or any of its Affiliates or Sublicensees) hereunder, including all development, regulatory and sales milestones, as well as royalty payments and any sharing of any sublicensing income or other amounts.   
7.10Records and Audit Rights.  Each Party shall keep complete, true and accurate books and records for the purpose of determining the amounts payable under this Agreement.  Such books and records shall be kept by such Party for at least [***] years (or such longer period as required by Applicable Law) following the end of the Calendar Year to which they pertain.  Each Party (the “Audited Party”) shall make such accounting records available, on reasonable notice sent by the other Party (the “Auditing Party”), for inspection during normal business hours, with not less than [***] Business Days’ advance written notice, by an independent certified public accounting firm nominated by such Auditing Party and reasonably acceptable for the Audited Party, for the purpose of verifying the accuracy of any statement or report given by the Audited Party and to verify the accuracy of the payments due hereunder for any Calendar Year.  Such auditor shall advise the Parties simultaneously promptly upon its completion of its audit whether or not the payments due hereunder have been accurately recorded, calculated, and reported, and, if not, the amount of such discrepancy.  Except in the case of willful misconduct or fraud, (a) a Party’s financial records with respect to a given period of time shall only be subject to one (1) audit per Calendar Year, and (b) the Auditing Party’s right to perform an audit pertaining to any Calendar Year shall expire [***] years after the end of such Calendar Year.  The auditor shall be required to keep confidential all information learned during any such inspection, and to disclose to the Auditing Party only such details as may be necessary to report the accuracy of the Audited Party’s statement or report.  The Auditing Party shall be responsible for the auditor’s costs, unless the auditor certifies an underpayment by the Audited Party that resulted from a discrepancy in a report that the Audited Party provided to the Auditing Party during the applicable audit period, which underpayment was more than [***] of the amount set forth in such report, in which case the Audited Party shall bear the full cost of such audit.  If such accounting firm identifies a discrepancy made during such period, any unpaid amounts or overpaid amounts that are discovered shall be paid/refunded promptly but in any event within [***] days of the date of delivery of such accounting firm’s written report so correctly concluding, or as otherwise agreed upon by the Parties.  The Auditing Party shall treat all financial information subject to review under this Section 7.10 in accordance with the confidentiality and non-use provisions of Article 8, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with the Audited Party obligating it to retain all such information in confidence pursuant to such confidentiality agreement.  Upon the expiration of [***] months following the end of any Calendar Year, royalty calculations with respect to such Calendar Year shall be binding and conclusive upon both Parties.

Exhibit 10.1

Unless an audit is ongoing with respect to such period, the Parties shall be released from any liability or accountability with respect to said calculations for such Calendar Year.  
7.11Taxes.  
7.11.1Withholding Taxes Generally.  Except as set forth in this Section 7.11, 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.  To the extent Seagen is required by Applicable Law to withhold any taxes, duties, levies, imposts, assessments, deductions, fees, and other similar charges by Applicable Law or any Governmental Authority (“Withholding Taxes”) on any payment to Lava, then Seagen will pay such Withholding Taxes to the applicable Governmental Authority, will make the payment to Lava of the net amount due after deduction or withholding of such taxes and will secure and send to Lava written evidence of such payment.  If Seagen intends to withhold any taxes from any payment under this Agreement (including with respect to any withholding under Section 7.11.2 below), Seagen shall inform Lava reasonably in advance of making such payment to permit Lava an opportunity to provide any forms or information or obtain any taxing authority exemption or reduction as may be available to reduce or eliminate such withholding.  In addition, Seagen agrees to reasonably cooperate with Lava in claiming refunds or exemptions from such deductions or withholdings under any relevant agreement or treaty which is in effect to ensure that any amounts required to be withheld pursuant to this Section 7.11.1 are reduced in amount to the fullest extent permitted by Applicable Law.
7.11.2German Withholding Tax.  Following the view of the German tax authorities, under current law, royalty income generated by a non-German licensor for the temporary licensing of rights that are entered in a German domestic public book or register is subject to German income tax pursuant to sec. 49 para. 1 German Income Tax Act (“GITA”).  Consequently, if any payments to be made to Lava under this Agreement are, in whole or in part, subject to withholding tax pursuant to sec. 50a para. 1 GITA (the “German WHT Requirement”), such tax shall be borne by Lava.  The following specific provisions shall apply with regard to the German WHT Requirement:
(a)Lava shall submit an application for an exemption certificate (Freistellungsbescheinigung) with the German Tax authorities establishing that pursuant to the double tax treaty between the Netherlands and Germany, the German WHT Requirement is not applicable to royalties paid to Lava.  Provided that such application for an exemption certificate has been made and proof of filing of such application furnished to Seagen prior to Seagen’s payment of the applicable payment hereunder, Seagen will not withhold any German withholding taxes from such payment.
(b)If the German tax authorities grant the exemption certificate application to Lava, then Seagen will not withhold German withholding tax during the period covered by the exemption certificate.
(c)If the German tax authorities deny Lava’s application for an exemption certificate, or if the withholding certificate expires or otherwise ceases to be applicable, 



CERTAIN CONFIDENTIAL INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND REPLACED WITH “[***]” BECAUSE IT IS NOT MATERIAL AND IS INFORMATION THAT THE COMPANY TREATS AS PRIVATE OR CONFIDENTIAL.
​
Exhibit 10.1

Seagen will begin to withhold German withholding taxes upon such date, including in the case of a denial of the application, retroactive withholding for payments made without withholding under Section 7.11.2(a).  Prior to the filing of an application for an exemption certificate, or if the events described in the preceding sentence occur, Lava shall then determine, reasonably and in good faith, what portion of the payments to be made to Lava hereunder are to be withheld in order to satisfy the German WHT Requirement.  Taking into account this assessment, Seagen shall withhold such amounts of German withholding taxes as it determines, reasonably and in good faith, to be required to be withheld under German tax law and remit such amounts to the competent German tax authority in due course.  Any amounts withheld and paid over to the German tax authority pursuant to the preceding sentence or in connection with any subsequent assessment of tax by the German tax authority with respect thereto shall be deemed as a payment to Lava in satisfaction of Seagen’s obligations under this Agreement.  
(d)In the event that the German tax authorities determine that the amounts remitted under Section 7.11.2(c) are insufficient to satisfy the German WHT Requirement or if German WHT Requirement is applicable to payments already made to Lava without withholding due to the denial of Lava’s exemption certificate application, then Lava shall indemnify and hold Seagen harmless from any taxes, interest or penalties arising from the German WHT Requirement.  Seagen may set off amounts paid to German authorities in connection with a subsequent assessment or any retroactive application of the German WHT Requirement against any further payments to be made by Seagen to Lava under this Agreement.   
(e)The Parties shall cooperate with each other in good faith with regard to the German WHT Requirement.  Seagen shall in particular (i) deliver without undue delay reasonable evidence of the payment to the competent German tax authority (e.g., a tax certificate); and (ii) use reasonable best efforts to minimize any possible German withholding obligation.  Lava shall in particular (i) provide to Seagen proof of the filing of the application for an exemption certificate and (ii) promptly notify Seagen of any approval or denial of such application.
(f)If and to the extent Seagen receives from a German tax authority a repayment of an amount previously withheld and remitted in respect of the German WHT Requirement, Seagen shall promptly repay such amount to Lava.
(g)Upon a change in applicable German tax law, Seagen agrees not to withhold German withholding taxes to the extent that the German WHT Requirement no longer applies as a result of such change in law.  
(h)In case of a conflict between this Section 7.11.2 and the other provisions of this Agreement, this Section 7.11.2 shall prevail. 
7.11.3U.S. Withholding Taxes.  Within two (2) Business Days after the Effective Date, Lava shall furnish to Seagen a true, correct and complete copy of IRS Form W-8BEN-E, Form W-8ECI, or other appropriate Form W-8 (collectively, “U.S. Tax Forms”).  Further whenever a lapse of time or change in circumstances renders such U.S. Tax Forms obsolete, expired or inaccurate in any respect, Lava shall deliver promptly to Seagen updated or other

Exhibit 10.1

appropriate U.S. Tax Forms or promptly notify Seagen in writing of its inability to do so.  
7.11.4VAT.  All payments under this Agreement are exclusive of any value added, sales and use, excise, stamp, or similar country-specific, governmental or local taxes (collectively, “VAT”).  If any VAT is required in respect of any payments under Applicable Law by the Party making the supply or providing the service, the other Party shall pay VAT at the applicable rate in respect of any such payments upon the receipt of a valid VAT invoice in the appropriate form issued in respect of those payments, such VAT to be payable on the due date of the payments to which such VAT relates.  The Parties will reasonably cooperate to issue valid VAT invoices for all amounts due under this Agreement consistent with VAT requirements.  A Party shall not be responsible for any penalties and interest resulting from the failure by the other Party to collect (if not included on a valid VAT invoice) or remit any such VAT.  The Parties shall reasonably cooperate to report and claim refunds or exemptions from any such VAT imposed on the transactions contemplated in this Agreement to the fullest extent permitted by Applicable Law and to timely file all required VAT tax returns.  Notwithstanding the generality of the foregoing, Lava acknowledges and agrees that, based on the facts and circumstances in effect as of the date hereof, no VAT is required to be charged on any of the payments to be received from Seagen under this Agreement. 
7.12Blocked Currency.  If by Applicable Law in a country or jurisdiction in the Territory, conversion into USD or transfer of funds of a convertible currency to the United States becomes materially restricted, forbidden or substantially delayed, then Seagen shall promptly notify Lava and, thereafter, amounts accrued in such country or jurisdiction under this Article 7 shall be paid to Lava (or its designee) in such country or jurisdiction in local currency by deposit in a local bank designated by Lava and to the credit of Lava, unless the Parties otherwise agree.
Article 8​

Notwithstanding the foregoing, in the event that a Party is required to make a disclosure of the other Party’s Confidential Information pursuant to Section 8.3.3-8.3.4, it will, except where impracticable, promptly inform the other Party of the disclosure that is being sought in order to provide the other Party an opportunity to challenge or limit the disclosure obligations, and, if requested by the other Party, cooperate in all reasonable respects with the other Party’s efforts to obtain confidential treatment or a protective order with respect to any such disclosure, at the other Party’s expense.

9.1.1By Lava.  In the event either Party desires to submit any publication or make any presentation, including any abstract, manuscript, poster, or slide presentation, in each case relating to any Licensed Compound or Licensed Product (each a “Publication”), it may only submit or present a Publication in accordance with this Section 9.1.1; provided, however, that the following shall not be subject to the obligations imposed by this Section 9.1.1: [***] (b) Publications that contain previously published information only, (c) Publications that constitute permitted disclosures under Section 8.3.5, and (d) in the case of Seagen, publications pertaining to clinical studies of Licensed Products by Seagen, its Affiliates or Sublicensees or publications made by or jointly with an academic or not-for-profit institution pursuant to an agreement with Seagen, its Affiliates or Sublicensees.

Exhibit 10.1

10.2.2Joint Collaboration Patents.  Seagen shall have the first right, but not the obligation, to Prosecute and Maintain the Joint Collaboration Patents in both Parties’ names, and the Parties shall share [***] the costs for such Prosecution and Maintenance.  The Party handling the Prosecution and Maintenance of a given Joint Collaboration Patent shall, through the Patent Committee, keep the other Party reasonably informed of the status of such Joint Collaboration Patent and shall provide the Patent Committee with (a) copies of all correspondence received from any patent authority in connection with the Prosecution and Maintenance of the Joint Collaboration Patent, and (b) drafts of any filings or responses to be made to patent authorities in advance of submitting such filings or responses so as to allow for a reasonable opportunity for the other Party to review and comment thereon.  The prosecuting Party shall incorporate the other Party’s reasonable comments in good faith.  The prosecuting Party shall notify the other Party of its intention to suspend or cease the Prosecution and Maintenance of any Joint Collaboration Patent and in such event, the other Party, at its discretion and at its sole expense, shall have the right to continue Prosecution and Maintenance of such Joint Collaboration Patent in both Parties’ names, subject to the foregoing information sharing obligation and review and comment rights.
10.2.3Lava Patents.  
(a)Lava Patents.  Lava and Seagen will cooperate in the Prosecution and Maintenance of the Lava Patents other than the Seagen Controlled Patents, which are governed by Section 10.2.4.  Lava will, through the Patent Committee, keep Seagen reasonably informed as to the Prosecution and Maintenance of such Lava Patents, including providing the Patent Committee with periodic updates on the status of the Lava Patents that are necessary or reasonably useful for the development, manufacture or commercialization of Licensed Products.  Without limiting the foregoing, with respect to any claims of such Lava Patents that Cover the composition of matter, making, or use of Licensed Compounds or Licensed Products and [***] (such claims the “Licensed Product-Specific Claims”), Lava will provide the Patent Committee with (a) copies of all correspondence received from any patent authority in connection with the Prosecution and Maintenance of such Licensed Product-Specific Claims, and (b) drafts of any filings (including draft applications) or responses to be made to patent authorities in connection with such Licensed Product-Specific Claims in advance of submitting such filings or responses so as to allow for a reasonable opportunity for Seagen to review and comment thereon.  Lava will implement all reasonable comments and directions of Seagen in Prosecuting and Maintaining such Licensed Product-Specific Claims.  For clarity, the Licensed Product-Specific Claims may include claims that Cover composition of matter, making or use of the [***].  In addition, Lava shall not (i) take any action that would materially affect or change the scope of any Licensed Product-Specific Claim, or (ii) file any new Licensed Product-Specific Claim, in each case without Seagen’s prior written consent.  If Lava determines not to file or to abandon or otherwise not maintain any pending or issued Lava Patent including a Licensed Product-Specific Claim, then Lava shall inform Seagen of such decision promptly, but in any event at least [***] days prior to allowing such Licensed Product-Specific Claim to lapse or become abandoned or unenforceable, and Seagen shall thereafter have the right, but not the obligation, to cause Lava to continue with the Prosecution and Maintenance of such Licensed Product-Specific Claim at Seagen’s expense.  Lava agrees not to take any of the following actions in Prosecuting and Maintaining the Lava Patents without Seagen’s prior written consent: (i) make any argument on the record which calls into question or

​
Exhibit 10.1

otherwise seeks to limit the scope or priority of any disclosure or claim of a Seagen Controlled Patent or Licensed Product-Specific Claim, or (ii) modify the inventorship or priority claim of any Lava Patent to which a Seagen Controlled Patent or a Lava Patent including a Licensed Product-Specific Claim claims priority. 
(b)Lava Platform Improvement Patents. Lava shall use commercially reasonably efforts to file Patent Rights, as permitted by applicable patent laws, Covering [***] in the Territory.  Section 10.2.3(a) shall apply to the Prosecution and Maintenance of any Lava Platform Improvement Patent (which, for clarity, shall be a Lava Patent hereunder), provided that notwithstanding anything to the contrary herein, if Lava determines not to file, or to abandon or otherwise not maintain any pending or issued Lava Platform Improvement Patent without the filing of a continuation or divisional application, then Lava shall inform Seagen of such decision promptly, but in any event at least [***] days prior to allowing such Lava Platform Improvement Patent to lapse or become abandoned or unenforceable, and Seagen shall thereafter have the right, but not the obligation, to assume control of the Prosecution and Maintenance of such Patent Right in Lava’s name, at Seagen’s sole cost and expense.  If Seagen so assumes control, then the applicable Patent Right will not be considered a Lava Patent for purposes of Section 10.2.3(a) or determining any royalty payments due hereunder.  In Prosecuting and Maintaining any such Patent Right for which Seagen assumes control, Seagen agrees not to take any of the following actions without Lava’s prior written consent: (i) make any argument on the record which calls into question or otherwise seeks to limit the scope or priority of any disclosure or claim of any other Lava Patent, or (ii) modify the inventorship or priority claim of any such Patent Right.
10.2.4Seagen Controlled Patents.  
(a)With respect to any Licensed Product, on a country-by-country basis and as permitted by applicable patent laws, the Parties intend for one (1) or more Patent Rights to issue to serve as the basis for a Patent Term Extension with respect to such Licensed Product.  As such, after the Effective Date, the Patent Committee will meet and decide the countries in which Lava will file (or cause to be filed) one (1) or more national stage entries based on [***] and any other Lava Patent from which one (1) or more Licensed Product-Specific Claims can be filed.  With respect to each such country and applicable Lava Patent, the Parties will discuss, via the Patent Committee, the appropriate claim strategies for such national stage entries in light of the Parties’ objective of obtaining in such country the issuance of [***] lines of patent cases ([***]) with the maximum patent term.  Upon the written request of Seagen, for each applicable Lava Patent, Lava will file (or caused to be filed) in each country decided by the Patent Committee one (1) or more national stage entries of such Lava Patent (each a “National Stage Entry”), and, if further requested by Seagen in writing, [***] lines of patent applications from such National Stage Entries as follows: [***] (each such Patent Right a “Seagen Controlled Patent”), and [***].  For clarity, the Seagen Controlled Patents may include claims that Cover the composition of matter, making or use of [***].  For further clarity, the National Stage Entries and Patent Rights described in subsection (ii) above shall be Lava Patents, including for purposes of Section 10.2.3(a).  Seagen will [***] that are Seagen Controlled Patents in any country or jurisdiction outside of [***].

​
Exhibit 10.1

(b)Notwithstanding anything herein to the contrary, any Patent Right Covering a [***] (each such Patent Right a [***]) shall be considered a Seagen Controlled Patent for purposes of this Article 10, including Section 10.2.4, Section 10.3 and Section 10.5; provided, however, that the claims of any such [***] shall not Cover the composition of matter, making or use of a compound other than the Licensed Compounds or a product other than the Licensed Products.   
(c)Except as expressly set forth herein, Seagen shall, [***], control the Prosecution and Maintenance of the Seagen Controlled Patents (including the initial drafting of the claims of such Seagen Controlled Patents that will be filed in accordance with Section 10.2.4(a)(i)).  Seagen will provide Lava with (a) copies of all correspondence received from any patent authority in connection with the Prosecution and Maintenance of the Seagen Controlled Patents, and (b) drafts of any filings or responses to be made to patent authorities in advance of submitting such filings or responses so as to allow for a reasonable opportunity for Lava to review and comment thereon, and Seagen shall consider all reasonable comments made thereon by Lava in good faith.  [***].  Seagen agrees not to take any of the following actions in Prosecuting and Maintaining the Seagen Controlled Patents without Lava’s prior written consent: (i) make any argument on the record which calls into question or otherwise seeks to limit the scope or priority of any disclosure or claim of any other Lava Patent, or (ii) modify the inventorship or priority claim of any Seagen Controlled Patent.  Seagen shall have the right to file substitutions, continuations, continuations-in-part, continued prosecution applications, divisional applications and renewals of such Seagen Controlled Patents, so long as the claims thereof are limited to Licensed Product-Specific Claims, and such Patent Rights shall be considered Seagen Controlled Patents for purposes of this Agreement.
(d)If Seagen determines to abandon or otherwise not maintain any pending or issued Seagen Controlled Patent in a particular country, and no other Seagen Controlled Patent that is a substitution, continuation, continuation-in-part, continued prosecution application, divisional application or renewal thereof filed by Seagen is pending in such country, then Seagen shall inform Lava of such decision promptly, but in any event at least [***] days prior to allowing such Seagen Controlled Patent to lapse or become abandoned or unenforceable, and Lava shall thereafter have the right, but not the obligation, to cause Seagen to transfer the control of the Prosecution and Maintenance of such Seagen Controlled Patent to Lava, and to execute any document and take or cause to be taken any action reasonably necessary to effectuate such transfer of control.
10.2.5Seagen Collaboration Patents.  As between the Parties, Seagen shall have the sole right and responsibility, at its sole cost, to control the Prosecution and Maintenance of the Seagen Collaboration Patents.
10.2.6Patent Committee.
(a)Establishment.  Within [***] after the Effective Date, the Parties shall establish a patent committee comprised of one (1) representative from each Party (the “Patent Committee”).  Each representative of a Party shall have sufficient seniority and expertise in the

(b)Meetings.  The Patent Committee shall convene at such times, places and frequencies as the Patent Committee determines is necessary.  Meetings may be conducted by telephone, video-conference or in person, as agreed by the Patent Committee, and each Party will bear all expenses it incurs in regard to participating in such meetings.  
(c)Responsibilities.  The Patent Committee shall be responsible for (i) resolving any issues relating to inventorship or ownership of Collaboration Know-How (or Patent Rights therefor) in accordance with the terms of Section 10.1.1, (ii) determining the countries in which Lava will file (or cause to be filed) national stage entries of applicable Lava Patents, and discussing claim strategies for such national stage entries, pursuant to Section 10.2.4(a), (iii) facilitating cooperation between the Parties with respect to the Prosecution and Maintenance of the Joint Collaboration Patents in accordance with Section 10.2.2, (iv) facilitating the sharing of information and cooperation (if applicable) between the Parties with respect to the Prosecution and Maintenance of the Lava Patents in accordance with Section 10.2.3 and the Seagen Controlled Patents in accordance with Section 10.2.4, (v) discussing strategies and sharing information with respect to which Lava Patents, Joint Collaboration Patents and Seagen Collaboration Patents, if any, shall be a basis for obtaining a Patent Term Extension with respect to a Licensed Product, and (vi) executing such other responsibilities as may be mutually agreed to in writing by the Parties from time to time.
(d)Decisions.  Except as otherwise provided herein, all decisions of the Patent Committee shall be made by consensus, with each Party having one (1) vote.  If the Patent Committee cannot agree on a matter within the Patent Committee’s authority within [***] Business Days after it has met and attempted to reach such decision, then either Party may, by written notice to the other, have such issue referred to the IP Executives for resolution.  The Parties’ respective IP Executives shall meet within [***]after such matter is referred to them and shall negotiate in good faith to resolve the matter.  If the IP Executives are unable to resolve the matter within [***], then such dispute shall be resolved pursuant to Section 14.6 of this Agreement, provided that:
(i)Seagen shall have the final decision-making authority with respect to determining the countries in which Lava will file national stage entries pursuant to Section 10.2.4(a); and
(ii)if the dispute relates to inventorship and ownership of Collaboration Know-How, then the dispute shall promptly be referred to a patent counsel selected by the Patent Committee who (and whose firm, if applicable) (a) is not, and was not at any time during the [***] years prior to such dispute, an employee, consultant, legal advisor, officer, director or stockholder of, and does not have any conflict of interest with respect to, either Party, (b) has at least [***] years’ experience practicing patent law in the life sciences industry, and (c) possesses expertise with respect to Antibodies, in each case ((a), (b), or (c)), unless otherwise

​
Exhibit 10.1

agreed to by the Patent Committee.  Such patent counsel shall determine inventorship and ownership of Collaboration Know-How in accordance with this Agreement, and such patent counsel’s determination shall be binding upon the Parties.  Expenses of the patent counsel shall be shared equally by the Parties.
10.3Cooperation for Patent Extensions.  Notwithstanding anything herein to the contrary, (a) the Parties shall discuss in good faith, through the Patent Committee, strategies  to avoid the loss of any potential rights under the U.S. Drug Price Competition and Patent Term Restoration Act of 1984, the Supplementary Certificate of Protection of the Member States of the European Union and other similar measures in any other country or jurisdiction (each a “Patent Term Extension”) with respect to the Licensed Products and the Lava Patents (including any Seagen Controlled Patents), Joint Collaboration Patents and Seagen Collaboration Patents, and (b) Seagen shall have the sole right to determine which of the Lava Patents (including any Seagen Controlled Patents), Joint Collaboration Patents and Seagen Collaboration Patents, if any, shall be a Patent Right for which Seagen will seek to obtain a Patent Term Extension for a Licensed Product, provided that Seagen shall not seek a Patent Term Extension for any Lava Patent that is not a Seagen Controlled Patent with respect to any Licensed Product without Lava’s prior written consent, such consent not to be unreasonably withheld, conditioned or delayed.  Lava shall reasonably cooperate with Seagen in obtaining any such Patent Term Extension in accordance with this Section 10.3, including that Lava shall execute any authorization or instruments, make any filings, or take such further actions as may be requested by Seagen to implement and obtain any such Patent Term Extension.  Notwithstanding the foregoing, to the extent a Lava Patent that contains Licensed Product-Specific Claims exists in a particular country in which there is no Seagen Controlled Patent that would qualify for Patent Term Extension, then (i) Seagen shall have the right to obtain a Patent Term Extension for such Lava Patent in such country for the Licensed Products, and (ii) Lava shall not seek a Patent Term Extension for such Lava Patent without Seagen’s prior written consent.
10.4Common Interest Disclosures.  With regard to any information or opinions exchanged pursuant to this Agreement by the Parties (or their Affiliates) regarding intellectual property owned by Third Parties, the Parties agree that they have a common legal interest in coordinating Prosecution and Maintenance of their respective Patent Rights, as set forth in this Article 10, and in determining whether, and to what extent, Third Party intellectual property rights may affect the conduct of the Development, Manufacturing or Commercialization of Licensed Compounds and Licensed Products, and have a further common legal interest in defending against any actual or prospective Third Party claims based on allegations of misuse or infringement of intellectual property rights relating to the Development, Manufacturing or Commercialization of Licensed Compounds and Licensed Products.  Accordingly, Seagen and Lava agree that all such information and materials obtained by Seagen or Lava from each other will be used solely for purposes of the Parties’ common legal interests with respect to the conduct of the Agreement.  All information and materials will be treated as protected by the attorney-client privilege, the work product privilege, and any other privilege or immunity that may otherwise be applicable.  By sharing any such information and materials, neither Party intends to waive or limit any privilege or immunity that may apply to the shared information and materials.  Neither Party shall have the authority to waive any privilege or immunity on behalf of the other Party without such other Party’s 



CERTAIN CONFIDENTIAL INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND REPLACED WITH “[***]” BECAUSE IT IS NOT MATERIAL AND IS INFORMATION THAT THE COMPANY TREATS AS PRIVATE OR CONFIDENTIAL.
​
Exhibit 10.1

prior written consent, nor shall the waiver of privilege or immunity resulting from the conduct of one Party be deemed to apply against any other Party.
10.5Patent Enforcement. 
10.5.1Notice.  Each Party shall notify the other within [***] Business Days of becoming aware of any alleged or threatened infringement by a Third Party of any Lava Patent (including, for clarity, any Seagen Controlled Patent) or Joint Collaboration Patent, which infringement adversely affects or could reasonably be expected to adversely affect the Development, Manufacture, or Commercialization of any Licensed Compound or Licensed Product in the Field in the Territory, and any related declaratory judgment or equivalent action alleging the invalidity, unenforceability or non-infringement of any such Patent Right (“Competitive Infringement”). 
10.5.2Enforcement.  
(a)Seagen (or its designee) shall have the first right, but not the obligation, to bring and control a legal action to enforce the Joint Collaboration Patents, Seagen Controlled Patents, Lava Platform Improvement Patents for which Seagen controls Prosecution and Maintenance and the Licensed Product-Specific Claims of any other Lava Patent against any Competitive Infringement in the Territory (each an “Enforcement Action”), [***].  Seagen shall keep Lava reasonably informed as to the status of any Enforcement Action and shall consider in good faith the comments of Lava with respect thereto.  
(b)If Seagen (or its designee) fails to file an Enforcement Action with respect to, or fails to take steps to abate, a Competitive Infringement in the Territory [***] pursuant to Section 10.5.1, then Lava shall have the right, but not the obligation, to bring and control an Enforcement Action for the Joint Collaboration Patents, Seagen Controlled Patents or Licensed Product-Specific Claims of any other Lava Patent (or take over control of a discontinued Enforcement Action) with respect to such Competitive Infringement, at its sole cost and expense, provided that (a) Lava shall keep Seagen reasonably informed as to the status of such Enforcement Action and shall consider in good faith the comments of Seagen with respect thereto, and (b) if Seagen provides a reasonable, objective rationale for not pursuing such Enforcement Action (including a substantive concern regarding counter-claims by the infringing Third Party with respect to Patent Rights owned or controlled by Seagen), then the Parties shall discuss in good faith Seagen’s concerns and Lava shall not have the right to bring and control any Enforcement Action without Seagen’s consent.
(c)For clarity, Lava shall have the sole right to bring and control any legal action to enforce the claims of the Lava Patents that are not Licensed Product-Specific Claims, provided, however, that Lava shall (i) keep Seagen reasonably informed as to the status of such legal action, and (ii) consider in good faith the interests of Seagen with respect to any such legal action.
10.5.3Cooperation.  In a connection with any Enforcement Action, each Party shall provide the enforcing Party with all reasonable assistance in such action, at such enforcing

Party’s request and expense, including joining such Enforcement Action if required by law or at the reasonable request of the enforcing Party.  The non-enforcing Party shall be entitled to separate representation in an Enforcement Action by counsel of its own choice and at its own cost and expense, but such Party shall at all times cooperate fully with the enforcing Party.  In addition, with respect to any Licensed Product-Specific Claims of a Lava Patent (other than a Seagen Controlled Patent or Lava Platform Improvement Patent for which Seagen controls Prosecution and Maintenance) enforced by Seagen in an Enforcement Action, Seagen shall (a) reasonably consult with Lava as to the proposed strategy for the enforcement of such Licensed Product-Specific Claims, (b) keep Lava reasonably informed of all material steps proposed to be taken and taken, and provide copies of all material documents filed or received, in connection with such Licensed Product-Specific Claims in such Enforcement Action, and (c) consider in good faith any comments from Lava with respect thereto.
10.5.4Settlement.  A settlement, consent judgment or other voluntary final disposition of a Competitive Infringement or Enforcement Action may be entered into by the enforcing Party without the consent of the non-enforcing Party; provided, however, that any such settlement, consent judgment or other disposition shall not, without the prior written consent of the non-enforcing Party, (a) impose any liability or obligation on the non-enforcing Party or any of its Affiliates, or (b) admit the invalidity or unenforceability of, or otherwise impair or materially adversely affect the scope of, any Patent Right owned or controlled by the non-enforcing Party, such consent to not be unreasonably withheld, conditioned or delayed.
10.5.5Recoveries.  Any recoveries resulting from an Enforcement Action brought pursuant to Section 10.5.2 shall be first applied against payment of each Party’s costs and expenses in connection therewith, provided that if such recovery is less than the Parties’ aggregate costs and expenses incurred in such action, such recovery shall be allocated between the Parties on a pro rata basis based on their relative costs and expenses incurred in such action.  Any such recoveries in excess of such costs and expenses shall be shared as follows, (a) [***] to the enforcing Party, and (b) [***] to the non-enforcing Party. 
10.5.6Joint Collaboration Patents (Other Infringement).  Each Party shall notify the other within [***] Business Days of becoming aware of any alleged or threatened infringement by a Third Party of any Joint Collaboration Patent, which infringement is not a Competitive Infringement.  Within [***], the Parties shall meet and mutually agree upon a strategy with respect to such Third Party infringement.
10.5.7Seagen Collaboration Patents.  Seagen shall have the sole right and authority, in its sole discretion, to enforce any Seagen Collaboration Patent or take steps to abate any alleged or actual Third Party infringement of any Seagen Collaboration Patent anywhere in the world.  Seagen shall be entitled to any recoveries resulting from any enforcement action of a Seagen Collaboration Patent brought by Seagen anywhere in the world.
10.5.8Biosimilar Action.  Each Party shall give written notice to the other Party [***] that a Third Party abbreviated biological product application pursuant to 21 U.S. CFR § 351(k) or any equivalent thereto (each a “Biosimilar Application”) for a product that is similar to

Exhibit 10.1

or interchangeable with a Licensed Product was accepted by a Regulatory Authority.  Following such notice, the Parties shall promptly meet to discuss a response to such Biosimilar Application, provided that to the extent permitted under Applicable Law, Seagen shall control any response to such Biosimilar Application.  The non-controlling Party shall provide all reasonable assistance and cooperation to the controlling Party with respect to such response, including making available to the controlling Party documents possessed by such other Party that are reasonably required by such controlling Party and making available personnel for interviews and testimony.  The Parties shall cooperate to compile an accurate list of all Patent Rights required to be provided by either Party pursuant to 42 U.S.C. Section 262(l)(3)(A) or any equivalent thereto.  Notwithstanding the foregoing, Seagen will retain final decision-making authority as to such listing of all applicable Patent Rights for such Licensed Product in connection with any Biosimilar Application.
10.5.9Patent Listings.  Seagen (or its designee) shall have the sole right and authority to list or de-list Patent Rights, including any Lava Patents, Joint Collaboration Patents and Seagen Collaboration Patents, in the FDA’s “Purple Book” or any equivalent thereto in any country in the Territory with respect to the Licensed Products.

Notwithstanding anything herein to the contrary, translations into English shall be the responsibility of, and at the sole cost and expense of, Lava.
14.4Severability.  Should one or more of the provisions of this Agreement become void or unenforceable as a matter of Applicable Law, then this Agreement shall be construed as if such provision were not contained herein and the remainder of this Agreement shall be in full force and effect, and the Parties will use their best efforts to substitute for the invalid or unenforceable provision a valid and enforceable provision that conforms as nearly as possible with the original intent of the Parties.

CERTAIN CONFIDENTIAL INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND REPLACED WITH “[***]” BECAUSE IT IS NOT MATERIAL AND IS INFORMATION THAT THE COMPANY TREATS AS PRIVATE OR CONFIDENTIAL.
​
Exhibit 10.1

Agreement or any Ancillary Agreement, including the formation, existence, validity, enforceability, performance, interpretation, breach, or termination hereof or thereof (a “Dispute”)  that is not an “Excluded Claim” (as defined below) shall be finally resolved in accordance with Section 14.6.2.

14.6.2Mediation; Arbitration.
(a)Mediation.  Either Party may refer any Dispute for resolution via mediation in accordance with the American Arbitration Association (“AAA”) Commercial Mediation Rules (“Mediation Rules”) in effect at such time.

The costs of mediation shall be shared equally by the Parties.
(b)Arbitration.  In the event the Parties are unable to resolve a Dispute via mediation in accordance with Section 14.6.2(a), either Party may submit such Dispute to be finally settled by arbitration administered by the AAA in accordance with the AAA’s Commercial Arbitration Rules in effect at the time of submission, as modified by this Section 14.6.2(b).

Each Party will appoint one (1) arbitrator and the third (3rd) arbitrator will be selected by the two (2) Party-appointed arbitrators, or, failing agreement within [***] days following appointment of the second arbitrator, by the AAA.  Such arbitration will take place in New York, New York and will be conducted in English.

14.6.4Excluded Claims.  As used in this Section 14.6, the term “Excluded Claim” means a dispute, controversy or claim that concerns (a) the validity or infringement of a 



CERTAIN CONFIDENTIAL INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND REPLACED WITH “[***]” BECAUSE IT IS NOT MATERIAL AND IS INFORMATION THAT THE COMPANY TREATS AS PRIVATE OR CONFIDENTIAL.
​
Exhibit 10.1

Patent Right, trademark, copyright or trade secret, or (b) any antitrust-, anti-monopoly- or competition-related Applicable Law.  Any action concerning Excluded Claims identified in clauses (a) or (b) of this Section 14.6.4 may be brought in any court having jurisdiction. 
14.6.5Equitable Relief.  Nothing in this Section 14.6 shall preclude either Party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, either prior to or during any mediation or arbitration, to protect the interests of such Party or to preserve the status quo pending the mediation or arbitration proceeding.
14.7Force Majeure.  Except for payment obligations hereunder, neither Party shall be responsible to the other for any failure or delay in performing any of its obligations under this Agreement or for other nonperformance hereunder, if such delay or nonperformance is caused by strike, fire, flood, earthquake, accident, war, act of terrorism, epidemic or pandemic, act of God or of the government of any country or of any local government (including emergency shut-down, lock-down or stay-at-home orders) or by any other cause unavoidable or beyond the control of any Party hereto (“Force Majeure”).  In such event, the Party affected will provide prompt notice thereof to the other Party and will use all reasonable efforts to resume performance of its obligations and will keep the other Party informed of actions related thereto, and the performance of any obligations of the Party not so affected, which obligations are directly dependent upon such performance by the affected Party, shall be tolled during such period.  If any such failure or delay in a Party’s performance hereunder continues for more than [***] days, the Parties may negotiate in good faith any modifications of the terms of this Agreement that may be necessary or appropriate in order to arrive at an equitable solution.
14.8Waivers and Amendments.  The waiver by either Party of any right hereunder, or of any failure of the other Party to perform, or of any breach by the other Party, shall not be deemed a waiver of any other right hereunder or of any other breach by or failure of such other Party whether of a similar nature or otherwise.  Any waivers under this Agreement must be in writing to be effective.  No provision of this Agreement may be amended or modified other than by a written document signed by authorized representatives of each Party.
