18.1 Licenses of Third-Party Intellectual Property. Where the JPC or JSC determines pursuant to Clause 11.7 that a licence of any Patent Rights or other intellectual property rights owned or controlled by Third Parties is necessary for Commercialisation, royalties or other payments payable under such licences shall be Shared Expenses and reconciled pursuant to Clause 20.4, save that Clause 18.2 shall apply to the extent possible in respect of royalties so payable. However, before obtaining any licence to a Third Party Patent Right, the JPC will discuss whether the Parties should approach the Third Party together for this purpose.

18.2 Third Party Patent Royalty Offset. If the JPC or JSC determines pursuant to Clause 11.7 that a licence under a Third Party Patent Right is necessary for Commercialisation of the Product in a country pursuant to Clause 18.1, then:

(A) Subject to Clause 18.2(B), GSK shall be entitled to deduct [***] percent [***] of any royalties paid by GSK, its Affiliates or sublicensees to such Third Party pursuant to such licence against the royalties owed to Genmab based on the Net Sales of the Product in that country; provided, however, that any amount that has not been so deducted in a particular Calendar Quarter may be deducted from royalties due in subsequent Calendar Quarters.

(B) Notwithstanding the foregoing, the deductions permitted in Clause 18.2(A) shall not cause the royalty rate payable on Net Sales to Genmab to be lower than [***] percent [***] of those relevant Net Sales (or [***] percent [***] of the relevant Net Sales where the operation of Clause 17.2 also applies), regardless of the total

amount of such Net Sales. Subject to the foregoing, any amount that has not been effectively deducted pursuant Clause 18.2(A) for whatever reason in a particular Calendar Quarter may be rolled over into subsequent Calendar Quarters until the full amount has been fully credited against royalties due in subsequent Calendar Quarters.

(C) Any other payments required to be made under any license to Third Party Patent Rights such as, but not limited to, license fees and milestones, (but not including any royalties incapable of deduction pursuant to Clause 18.2(A) due to the operation of Clause 18.2(B)) shall be Shared Expenses for the purposes of Clause 20.4.

19. Other provisions relating to payments

19.1 Invoices. All invoices provided to GSK hereunder should include the payee’s bank details and Genmab’s contact name for issue resolution, and be sent to Corporate Accounting and Licensing at GSK. Additional details regarding the method of sending invoices to GSK, contact names and addresses will be provided to Genmab by GSK upon execution of this Agreement.

19.2 Royalty Rate Application. The royalty rates set forth above in Clause 17.1 are meant to be applied in turn and are not meant to be exclusive of each other. By way of example, if Net Sales of the Product equal [***] DKK in a Calendar Year, then the royalty rate payable on the first [***] DKK of Net Sales of the Product will be [***] percent [***] the royalty rate on the next [***] DKK will be [***] percent [***] the royalty rate payable on the next [***] DKK will be [***] percent [***] the royalty rate payable on the next [***] DKK will be [***] percent [***] and the royalty rate payable on the remaining [***] DKK will be [***] percent [***] for a total payment of [***] DKK for the Net Sales of the Product in such Calendar Year.

19.3 Single Royalty. Save as provided expressly herein, nothing shall obligate GSK and/or its Affiliates or its sublicensees to pay or cause to be paid to Genmab more than one royalty on any unit of Product, irrespective of how many Licensed Patents may cover such Product.

19.4 Payments Pursuant to [***] License. All amounts due pursuant to Clause 17.4 of this Agreement shall be paid by or on behalf of GSK free and clear of and without deduction or deferment in respect of any withholding of taxes or any other demand, set-off, counterclaim or other dispute. Where such amounts due to be paid by or on behalf of GSK hereunder are subject to taxes by way of withholding or similar taxes, GSK shall be obliged to pay to Genmab such additional amount as would ensure that after any such deductions or withholdings have been made by GSK or its Affiliates or sublicensees Genmab receives a sum equal to the amount that it would otherwise have received in the absence of any such deductions or withholdings. In such circumstances, the Parties shall do all such lawful acts and things and sign all such lawful deeds and documents as either Party may reasonably request from the other Party to enable Genmab and GSK or its Affiliates or sublicensees to take advantage of any applicable legal provision or any

double taxation treaties with the object of paying the sums due to Genmab hereunder without withholding or deducting any tax.

If the financial year of [***] changes from time to time during the Term, then the Relevant Year shall be changed from time to time accordingly upon [***] receipt of notice of such change from [***]. However, if [***] and [***] agree in writing that any royalties payable by [***] to [***] with respect to the sale, transfer or other disposal by [***], its

Affiliates or sublicensees of Product hereunder may be paid by [***] to [***] and by [***] to [***] on a Calendar Year-by-Calendar Year basis instead of on a [***] financial year-by-[***] financial year basis, then the Relevant Year for the Term shall be January 1st to December 31st upon [***] receipt of notice of such agreement from [***].

20. Records

20.1 Record Retention: Royalties. Both GSK and Genmab shall maintain (and shall procure that their Affiliates and sublicensees maintain) accurate books and records which enable the verification of the calculation of royalties payable hereunder, and of royalties payable by Genmab to Medarex under the Medarex License with respect to the sale by GSK, its Affiliates or sublicensees of Product.

20.2 Audit. Upon [***] prior notice from either Party, independent accountants selected by that Party (the “Auditing Party”), and approved by the other Party (the “Recording Party”), with such approval not to be unreasonably withheld or delayed, may have access to the books and records of Recording Party or its Affiliates and sublicensees during normal business hours to conduct a review or audit for the purpose of verifying the accuracy of the Recording Party’s, its Affiliates’ and sublicensees’ payments pursuant to this Agreement.

Genmab and GSK shall mutually determine a general strategy for such review or audit in advance of its conduct. Said accountants shall not disclose to the Auditing Party any information except that which should properly be contained in a royalty report required under this Agreement. The Recording Party shall receive a copy of any report issued by the auditors concurrently with receipt by the Auditing Party. All information contained in any such report shall be deemed to be “Confidential Information” of the Recording Party, subject to the terms and conditions of Clause 12 hereof. If any review or audit performed under this Clause shall indicate that any payment due hereunder was underpaid, the Recording Party shall promptly pay to the Auditing Party the amount of such underpayment, together with interest thereon from the date such underpayment was due, at the annual rate of [***] percent [***] per annum above the Denmark National Bank’s Official discount rate, assessed from the thirty-first (31st) day after the due date of the payment.

respect to such payments. If any audit performed under this Clause shall indicate that any payment due from [***] to Genmab or from Genmab to Medarex was underpaid by more than [***] percent [***] due to non-compliance by GSK, its Affiliates or sublicensees with this Agreement, [***] shall pay the costs of the inspection but [***] shall be responsible to Medarex for paying such underpayment, and [***] shall promptly reimburse such underpayment to [***] and pay to [***] interest on such underpayment from the date such amount(s) were due from Genmab to Medarex, at the prime rate reported by the Chase Manhattan Bank, New York, New York plus [***] percent [***], to defray any interest on such underpayment that Genmab may be obliged to pay Medarex. Notwithstanding the foregoing, Genmab will, upon [***] request, make available to Medarex any records or report of any audit which Genmab has performed and will use its Commercially Reasonable Efforts to cause Medarex to accept the same in place of performing its own audit. For the avoidance of doubt, if Medarex discovers an underpayment of any amounts due from Genmab to Medarex through no fault of [***], then [***] will not pay the costs of the inspection.

20.4 Financial Reconciliation. Within [***] days after the end of each Calendar Quarter, the Parties shall prepare a reconciliation report for such Calendar Quarter (the “Reconciliation Report”). The Reconciliation Report shall set forth, in reasonable detail, the following:

(B) a statement of total Shared Expenses, calculated by adding each Party’s Incurred Shared Expenses (the “Total Shared Expenses”);

20.5 Payment. Within [***] days after preparation of a Reconciliation Report, GSK or Genmab, as the case may be, shall pay the Reconciliation Payment to the other Party.

20.6 Manner of Payments. All sums due to Genmab or GSK hereunder shall be payable by bank wire transfer in immediately available funds to such bank account(s) as Genmab and GSK, respectively, shall designate from time to time.

20.7 Interest on Late Payments. If a Party shall fail to make a payment pursuant to this Agreement when due, any such late payment shall bear interest, to the extent not prohibited by Law, at the annual rate of [***] percent [***] per annum above the Denmark National Bank’s Official discount rate, effective for the first date on which

payment was delinquent and calculated on the number of days such payment is overdue or, if such rate is not regularly published, as published in such source as the Parties agree.

20.8 Withholding Taxes. Save as provided to the contrary in this Agreement, any taxes, levies or other duties paid or required to be withheld or deducted under the appropriate Laws by one of the Parties on account of monies payable to the other Party under this Agreement shall be deducted from the amount of monies otherwise payable to the other Party under this Agreement. The withholding Party shall secure and send to the other Party within a reasonable period of time proof of any such taxes, levies or other duties paid or required to be withheld by the withholding Party for the benefit of the other Party. The Parties shall co-operate reasonably with each other to ensure that any amounts required to be withheld by either Party are reduced in an amount to the fullest extent permitted by Law. Any interest, penalties or other charges imposed by a governmental authority as a result of a failure by the withholding party to pay such taxes, levies or other duties shall be the responsibility of the withholding party. The other Party will give the withholding Party any information necessary to determine such taxes, levies or other duties. No deduction shall be made, or a reduced amount shall be deducted, if the other Party furnishes a document from the appropriate governmental authorities to the withholding Party certifying that the payments are exempt from such taxes, levies or other duties or subject to reduced tax rates, according to the applicable convention for the avoidance of double taxation.

20.9 VAT. All sums payable under or pursuant to this Agreement are exclusive of VAT. Accordingly, where any taxable supply for VAT purposes is made under or in connection with this Agreement by one Party to the other, the recipient of that supply shall, in addition to any payment for that supply, pay to the supplier such VAT as is chargeable in respect of the supply at the same time as payment is due or in any other case when demanded by the supplier.

25. Dispute Resolution

25.1 Objective. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes (“Disputes”) occurring with respect to this Agreement in an expedient manner by mutual co-operation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Clause 25 if and when a Dispute occurs with respect to this Agreement; provided, that the Parties will use good faith efforts to resolve Disputes at the JSC or Senior Management level.

25.2 Resolution by the JSC and Senior Managers. Unless otherwise specifically recited in this Agreement, any Disputes (other than those which are failures of the JSC to reach agreement within any period contemplated hereunder) relating to the collaboration shall be first referred to the JSC by either Party at any time after such Dispute has arisen; provided, however, that any Dispute relating to the scope, validity or enforceability of Genmab Patent Rights, GSK Patent Rights and any other relevant Intellectual Property Rights may only be determined in accordance with Clause 25.5 hereof. If the JSC is unable to resolve any Dispute within [***] of being requested by a Party to do so (or within such period of time specified hereunder), unless otherwise agreed by the Parties, or the JSC is unable to resolve a Dispute among its members, either Party may present the Dispute to the appropriate senior manager (“Senior Manager”) of each of Genmab

and GSK for resolution by providing a dispute notice (the “Dispute Notice”) to the Senior Manager and the other Party. With respect to Genmab, the Senior Manager will be [***], and for GSK, the Senior Manager will be [***]. The Dispute Notice shall set forth concisely the Dispute, the Parties’ respective positions, and the specific relief requested. If the Party providing the Dispute Notice (the “Complaining Party”) contends that the Dispute is a Reserved Dispute as defined in Clause 25.3 below, the Dispute Notice shall so state. Within [***] after receipt of the Dispute Notice, the other Party (the “Responding Party”) shall provide a concise written response (the “Response”) to the Dispute Notice to the Senior Managers and the Complaining Party. If the Responding Party does not agree with the Complaining Party’s contention regarding whether the Dispute is a Reserved Dispute, the Response shall so state. The Senior Managers shall attempt to resolve the Dispute within [***] after their receipt of the Response. If the Dispute Notice and Response indicate that the Parties are in disagreement about whether a Dispute is a Reserved Dispute, the Senior Managers shall also attempt to resolve that disagreement. In the event that the Senior Managers cannot resolve a Dispute within this period, unless otherwise agreed by the Parties, then all Reserved Disputes shall be referred for resolution in accordance with Clause 25.3, and any other Dispute may be referred by either Party to arbitration for resolution in accordance with Clause 25.4 upon written notice to the other Party. If the Senior Managers cannot reach agreement as to whether a Dispute is a Reserved Dispute, then that question shall also be submitted to arbitration with the underlying Dispute and shall be decided by the arbitrator(s) as an initial matter. For the avoidance of doubt, when the arbitrator determines that a Dispute is a Reserved Dispute, then the underlying Dispute will be finally decided by the Party who is charged with such Reserved Dispute.

25.3 Reserved Disputes. Certain disputes that are specifically defined below shall be finally decided by the Senior Manager of one of the Parties (“Reserved Disputes”). In such cases, the Senior Manager of that Party shall make his or her decision with regard to the Reserved Dispute within [***] of its referral and such decision shall be final and binding. Reserved Disputes shall not include Disputes with respect to the interpretation, breach, termination or invalidity of the Agreement.

(A) Genmab Reserved Disputes shall be Disputes with respect to:

(1) any amendment to [***]

(2) any aspect of the [***] and any related issues in each case arising out of [***]

(1) any aspect of the [***]

(2) any aspect of the [***]

(3) strategies related to [***]

(C) Any increase in the Budget shall not be deemed to be a Reserved Dispute, and must be resolved unanimously by the Parties.

25.4 Arbitration.

(A) The Parties agree that any Dispute referred for resolution by arbitration by a Party pursuant to this Clause shall be finally resolved through binding arbitration in accordance with [***] and judgment on the arbitration award may be entered in any court having jurisdiction thereof.

(B) The arbitration shall be conducted by a sole arbitrator, or if the Parties agree that a particular Dispute should be resolved by more than one arbitrator, then the number of arbitrators shall be [***]. The arbitrator(s) shall be experienced in the medical research or pharmaceutical business. The Parties shall cooperate to attempt to select the arbitrator(s) by agreement within [***] days of the initiation of arbitration. If agreement cannot be reached with such [***] days, then that [***] will submit a list of [***] qualified arbitrators from which each Party shall strike unacceptable entries; provided that each Party shall not strike more than [***] of the names without cause, and rank the remaining names. The [***] shall appoint the arbitrator(s) with the highest combined ranking(s). If these procedures fail to result in selection of the required number of arbitrators, the [***] shall appoint the arbitrator(s), allowing each side challenges for cause. The seat of arbitration shall be London, England. All proceedings and communications shall be in English. The decision of the arbitrator shall be final and binding upon the Parties and their Affiliates. The decision shall be rendered within [***] following commencement of arbitration, to be extended by no more than an additional [***] days as required for reasonable cause.

(C) Either Party may apply to the arbitrator 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. In addition to dealing with the merits of the case, the arbitration award shall fix the costs of the arbitration and decide which of the Parties shall bear such costs or in which proportion such costs shall be borne by the Parties. Except to the extent necessary to confirm an award or as may be required by law, neither a Party nor the arbitrator may disclose the existence, content, or results of an arbitration without the prior written consent of both Parties.

(D) The Parties agree that, in the event of a dispute over the nature or quality of performance under this Agreement, neither Party may terminate this Agreement until final resolution of the dispute through arbitration or other judicial determination. The Parties further agree that any payments to be made pursuant to this Agreement pending resolution of the dispute shall be deposited into an escrow account until an arbitrator or court determines whether or not such payments should be made, and such amounts will either be refunded to the payor or paid in accordance with the determination of the arbitrator or court.

25.5 Jurisdiction: Intellectual Property Rights. In respect of any Dispute relating to the determination of scope, .validity or enforceability of any Intellectual Property Rights, the Parties consent to the exclusive jurisdiction of the courts of the country the Laws of which cause that Intellectual Property Right to come into being and where such courts have jurisdiction the Dispute shall be determined according to the laws of that country.

26.1 Hart Scott Rodino, Closing Date.

(A) Each Party covenants and agrees to prepare and make appropriate filings under Title II of the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (in this Clause, the “Act”), as amended, and the rules promulgated thereunder within [***] after the date of mutual execution of this Agreement. The Parties agree to co-operate in the antitrust clearance process and to furnish promptly to the Federal Trade Commission and the Antitrust Division of the Department of Justice any additional information reasonably requested by them in connection with such filings. Each Party will be responsible for its own costs in connection with the filings described in this Clause.

(B) This Clause 26.1 shall bind the Parties upon the Execution Date but the remaining provisions of this Agreement shall not become effective until the date the waiting period provided by the Act having terminated or expired without any action by any government agency or challenge to the termination (which date shall be the “Closing Date”).

(C) In the event that antitrust clearance from the FTC and the Antitrust Division of the Department of Justice is not obtained within [***] after the Execution Date or such other date as the Parties may agree, the Agreement may be terminated by either Party on written notice to the other.

(D) In the event a provision of the Agreement needs to be deleted or substantially revised in order to obtain regulatory clearance, the Parties will negotiate in good faith a new provision which in its economic effect and scope of rights is sufficiently similar to the old provision that it can reasonably be assumed that the Parties would have entered into the Agreement with such new provision.

26.2 Right to Terminate for Breach. Except as otherwise provided herein, if either Party shall commit a material breach with respect to any material provision of this Agreement and the other Party shall have given the breaching Party written notice of such breach, the breaching Party shall have [***] to cure such breach; provided, that if there is a good faith dispute with respect to the existence of a material breach, the time for cure will be extended until such time as the dispute is resolved pursuant to Clause 25.4. If such breach is not cured within such [***] period, the non-breaching Party shall have the right, upon notice to the breaching Party and without prejudice to any other rights the non-breaching Party may have, to terminate this Agreement in its entirety, unless the JSC unanimously determines within [***] that the breaching Party is in the process of attempting in good faith to cure such breach, in which case, the [***] cure period shall be extended by an additional [***]. For the avoidance of doubt, the non-breaching Party may continue to exercise the licenses and other rights granted to it under this Agreement.

26.3 Right to Terminate upon Bankruptcy. Either Party may, in addition to any other remedies available to it by law or in equity, terminate this Agreement in its entirety, by notice to the other Party in the event (i) the other Party shall have become bankrupt or

shall have made an assignment for the benefit of its creditors; (ii) there shall have been appointed a trustee or receiver for the other Party for all or a substantial part of its property; or (iii) any case or proceeding shall have been commenced or other action taken by or against the other Party in bankruptcy or seeking reorganisation, liquidation, dissolution, winding-up, arrangement, composition or readjustment of its debts or any other relief under any bankruptcy, insolvency, reorganisation or other similar act or law of any jurisdiction now or hereafter in effect, and any such event shall have continued for [***] undismissed, unbonded and/or undischarged.

26.4 GSK’s Right to Terminate.

(A) GSK shall have the right to terminate this Agreement in its entirety or on a country-by-country basis at any time after the Closing Date by providing [***] months’ prior written notice to Genmab. Where GSK gives such notice, GSK will, at Genmab’s request, comply with its obligations in Clauses 27.2(A) - 27.2(I) from the date of giving such notice.

(B) Notwithstanding Clause 26.4(A), GSK may terminate the Agreement immediately following the withdrawal of Product from any market as a result of bona fide concerns that the Product is unsafe for administration to humans (a “Valid Safety Issue”), but will do so on a country-by-country, indication-by-indication or subpopulation-by-subpopulation basis only to the extent that the Valid Safety Issue applies within such countries or to such indications. Where GSK exercises its right under this Clause 26.4(B) then the costs of withdrawing the Product from Clinical Studies shall be shared equally between the Parties. Nothing in this Clause 26.4(B) shall prevent GSK from exercising its right under Clause 26.4(A) to terminate this Agreement in its entirety on giving nine (9) months’ prior, written notice.

(C) Following any delivery by GSK of notice of termination pursuant to this Clause 26.4, during the period of notice until the effective date of termination, GSK shall be required to observe its obligations hereunder regarding Development Costs and Shared Expenses budgeted to be incurred within the period of notice but shall not be required to initiate any new clinical or non-clinical studies, make any further filings for Regulatory Approvals other than as related to the prompt and complete transfer of Regulatory Approvals and development and commercial rights to Genmab, or launch the Product in any further countries.

(D) Following delivery by GSK of notice of termination pursuant to this Clause 26.4 (except for a Valid Safety Issue, which will be subject to Clause 27.2(J)), the Parties will cooperate in good faith to agree and implement a transition plan to give effect to Clauses 27.2(A) - 27.2(1). For the avoidance of doubt, all obligations of GSK to provide transition services to Genmab with respect to the Product in accordance with Clause 27.2 will terminate on the effective date of termination.

26.5 Genmab Right to Terminate for Failure to Launch. Genmab may terminate this Agreement on a Clause 26.5 Region-by-Clause 26.5 Region basis if any of the following occur:

(A) If GSK determines that it will not launch the Product in the first [***] to obtain Regulatory Approval as well as Price and Reimbursement Approval (where applicable) in a particular Clause 26.5 Region (as defined in Clause 26.5(C) below) within [***] following the later to occur of such Regulatory Approval and Price and Reimbursement Approval (where applicable), then GSK shall present its reasons therefor to the JSC. The JSC shall determine whether such determination to not launch is reasonable; provided, that if the JSC cannot agree, the decision will be made by arbitration in accordance with Clause 25.4. If it is determined in arbitration that GSK’s decision to not launch the Product in the first [***] in a particular Clause 26.5 Region is not reasonable, and GSK still chooses not to so launch then, subject to Clause 26.5(C), Genmab has the right (but not the obligation) to terminate GSK’s rights under this Agreement in such Clause 26.5 Region upon [***] written notice after the arbitration decision under Clause 25.4 with respect to such Clause 26.5 Region, provided that such notice is provided to GSK no later than thirty (30) days after the arbitration decision.

(B) If GSK determines that it will not launch the Product in the first [***] to obtain Regulatory Approval as well as Price and Reimbursement Approval (where applicable) in a particular Clause 26.5 Region within [***] months following such Regulatory Approval including Price and Reimbursement Approval (where applicable), then GSK shall present its reasons therefor to the JSC within such six (6) month period. The JSC shall determine whether such determination to not launch is reasonable; provided, that if the JSC cannot agree, the decision will be made by arbitration in accordance with Clause 25.4. If it is determined in arbitration that GSK’s decision to not launch the Product in the first Non-Oncology Indication in a particular Clause 26.5 Region is not reasonable and GSK still chooses not to so launch then, subject to Clause 26.5(C) Genmab has the right (but not the obligation) terminate GSK’s rights under this Agreement upon [***]’ written notice after the arbitration decisions under Clause 25.4 with respect to such Clause 26.5 Region; provided it is understood that such termination will be effective in such Clause 26.5 Region even if GSK has previously launched the Product for one or more [***] in the applicable Clause 26.5 Region, provided that such notice is provided to GSK no later than [***] days after the arbitration decision.

(C) For purposes of this Clause 26.5, “Clause 26.5 Region” shall mean either (A) the [***], (B) [***], or (C) [***]. For the avoidance of doubt, if GSK has consummated its First Commercial Sale of the Product in [***], [***], or [***], as applicable, within the [***] notice period set forth in each of Clause 26.5(A) and 26.5(B), then Genmab will not have the right to terminate GSK’s rights in [***], [***], or [***], as applicable.

(D) If Genmab has the right to terminate GSK’s rights to Product in both [***] and [***] under this Agreement pursuant to this Clause 26.5, then Genmab may give

GSK written notice of its intent to terminate the Agreement in its entirety; provided, that such notice is given no later than [***] after the date on which Genmab first had the right to terminate this Agreement in both [***] and [***].

27. Effects of Expiration and Termination.

27.1 Interests of Patients. In exercising their respective rights upon expiry or termination of this Agreement, the Parties shall do so taking into account the health and safety of any patients receiving any Product, in particular so as to ensure the orderly transition of those rights and responsibilities as they may affect supply and availability of the Product to such patients.

27.2 Effects of Expiry, Termination for GSK’s Breach or by GSK for Convenience. Upon the expiry of this Agreement, or its termination by Genmab pursuant to Clause 26.2 or 26.3 or by GSK pursuant to Clauses 21.4(C)(2)(c) or 26.4, and subject always to Clause 27.1:

(A) GSK, its Affiliates and its sublicensees shall immediately cease to use and thereafter refrain from using the Genmab Licensed Technology anywhere in the Territory;

(B) save as expressly provided herein, all rights of GSK hereunder relating to the Territory and all licences granted to GSK by this Agreement in respect of any country in the Territory shall cease and terminate and, where applicable, GSK shall assist Genmab in taking all steps necessary for the removal of the name of GSK, its Affiliates and its sublicensees from any patent register at any patent office where a patent licence has been recorded;

(D) Genmab shall have an exclusive, perpetual licence, with the right to sublicense, under the GSK Patent Rights, GSK Know-How, GSK’s rights to Joint Patent Rights and Joint Collaboration Technology, and GSK Trademarks owned by GSK directly related to the Product and used by GSK with respect to the Product prior to the effective date of such termination, solely for the purpose of Commercialising Product throughout the Territory; provided, that such license shall be [***] in the event of Genmab’s termination of the Agreement pursuant to Clause 26.2 or 26.3, but in the event of termination of this Agreement by GSK pursuant to Clause 26.4, Genmab will pay to GSK a royalty of [***] percent [***] of Net Sales by Genmab, its Affiliates or licensees for the use of such GSK Trademarks and the licence shall otherwise be fully paid-up and royalty-free.

(E) GSK shall promptly return to Genmab or destroy all Genmab Know-How in GSK’s or its Affiliates’ or its sublicensees’ possession or control;

(F) on written request by Genmab, GSK shall provide to Genmab or Genmab’s nominee(s) a copy of, and shall transfer, or cause to be transferred, to Genmab or Genmab’s nominee(s) ownership of all INDs, New Product Applications and Regulatory Approvals for the Product held by or on behalf of GSK, its Affiliates and sublicensees. Until such transfer is effected or if such transfer is not possible for legal or regulatory reasons, GSK shall ensure that Genmab shall have the right to access, use and cross-reference such INDs, New Product Applications and Regulatory Approvals. GSK shall consent and, where necessary, cause its Affiliates and its sublicensees to consent, for any relevant Regulatory Authority to cross-reference such data and information contained in such INDs, New Product Applications and Regulatory Approvals as may be necessary for the granting of second INDs, New Product Applications and Regulatory Approvals to Genmab or its nominee(s);

(G) on written request by Genmab, GSK or its Affiliates will assign to Genmab or its nominee any agreements between GSK or its Affiliates and Third Parties that are freely assignable and relate solely to Development, Manufacturing and Commercialisation in the Territory; and, in addition, on written request by Genmab, GSK shall transfer to Genmab or its nominee at no cost any master cell banks and other biological materials necessary for the Manufacture of the Product that are Controlled by GSK or its Affiliates in respect of the Global Territory;

(H) GSK shall promptly transfer to Genmab or its designee the common safety database for both clinical and post-marketing adverse event data for the Product; and

(I) GSK shall do all other things as Genmab may reasonably require to effect the orderly transition of its rights regarding any Commercialisation of the Product to Genmab.

(J) Notwithstanding the foregoing, to the extent GSK terminates the Agreement pursuant to Clause 26.4 for a Valid Safety Issue, Clause 27.2(D) will not apply.

(K) If the Agreement is terminated by GSK pursuant to Clauses 21.4(C)(2)(c) or 26.4(A), then, upon Genmab’s subsequent Commercialisation of the Product, Genmab shall pay to GSK a royalty of [***] percent [***] of Net Sales by Genmab, its Affiliates or sublicensees of the Product billed or invoiced by Genmab, its Affiliates or sublicensees and sold for use in an indication for which Development Costs of a Completed Phase III Clinical Trial (other than an Ongoing Pivotal Study) for such indication were shared by GSK under the terms of this Agreement. Such royalties would be payable on a country-by-country basis for so long as such Product is sold by Genmab, its Affiliates or sublicensees.

27.3 Effects of Termination in a Clause 26.5 Region for GSK’s Failure to Launch. Upon termination by Genmab in a Clause 26.5 Region pursuant to Clause 26.5:

(A) GSK, its Affiliates and its sublicensees shall immediately cease to Commercialise the Product in that Clause 26.5 Region;

(B) Genmab may itself (or may license to any Third Party in its absolute discretion the right to) Commercialise the Product in that Clause 26.5 Region, and for this purpose:

(1) That Clause 26.5 Region shall be deemed excluded from the Territory for the purposes of Clause 8.1(A) and 8.1(B);

(2) Genmab and GSK and their Affiliates shall be relieved of the observance of its covenant at Clause 21.4(B) as it relates to that Clause 26.5 Region;

(3) The Trademark Licence granted to GSK shall cease to include that Clause 26.5 Region (and Genmab may therefore use the trademark “[***]” within that Clause 26.5 Region in its absolute discretion);

(4) Genmab shall have (or where appropriate, continue to have) an exclusive, perpetual, licence throughout the Clause 26.5 Region, with the right to sublicense, under the GSK Patent Rights, any Joint Patent Rights, GSK Know-How and the GSK Trademarks solely owned by GSK and the Joint Collaboration Technology but, in each case above, only to the extent GSK can legally do so and only to the extent directly related to the Commercialisation of the Product as carried out by GSK with respect to Product prior to the effective date of such termination in such Clause 26.5 Region; and with respect to GSK Trademarks, only to the extent such GSK Trademark is not being used in connection with the Commercialisation of the Product outside of the Clause 26.5 Region. Such licence shall be [***] except as regards use of the GSK Trademarks, in respect of which Genmab shall pay GSK a royalty of [***] percent [***] of Net Sales by Genmab, its Affiliates or licensees;

(5) For a period of [***] following the effective date of termination in a particular Clause 26.5 Region, GSK shall do all other things as Genmab may reasonably require to effect the orderly transition of its rights regarding the Product to Genmab, [***], in respect of that Clause 26.5 Region (including, where appropriate, the amendment of this Agreement or any of the documents referred to herein), provided that GSK shall not be required to provide unreasonable personnel support in carrying out such obligations under this provision;

GSK shall consent and, where necessary, cause its

Affiliates and its sublicensees to consent, for any relevant Regulatory Authority to cross-reference such data and information contained in such INDs, New Product Applications and Regulatory Approvals as may be necessary for the granting of second INDs, New Product Applications and Regulatory Approvals to Genmab or its nominee(s) in respect of that Clause 26.5 Region;

(7) on written request by Genmab, GSK or its Affiliates will assign to Genmab or its nominee any agreements between GSK or its Affiliates and Third Parties that are freely assignable (and use their Commercially Reasonable Efforts to novate to Genmab any which are not) and relate solely to Commercialisation in the Clause 26.5 Region but only to the extent such is legally possible;

(8) if GSK cannot assign Manufacturing contracts to Genmab because it requires its own supply of Product outside of the terminated Clause 26.5 Region, then GSK and Genmab shall enter into a supply agreement pursuant to which GSK shall provide commercial supply of Product for Genmab for purposes of Genmab’s Commercialisation activities in the terminated Clause 26.5 Region at GSK’s cost plus shipping. Nothing herein will require GSK to supply Genmab with Genmab’s commercial requirements of Product for the terminated Clause 26.5 Region in such a manner that may result in the shortage of any commercial supply required for GSK’s Commercialisation or clinical development activities outside the terminated Clause 26.5 Region, and in the case where GSK is not able to provide Genmab with its commercial requirements of Product for the applicable Clause 26.5 Region Genmab will have the right to establish its own source of supply of Product for such Clause 26.5 Region;

Following the effective date of termination of this Agreement, GSK, its Affiliates (and any Approved Sublicensees) shall have the right to sell their inventory of the Product for a period of [***] from the date of termination provided that GSK complies with the applicable provisions of Clauses 16-20.

27.5 Survival of certain Clauses. Upon termination of this Agreement for any reason whatever, the rights and obligations of the Parties under this Agreement shall terminate and be of no future effect, except as described below:

(A) termination shall not affect or prejudice any right to damages or other remedy which the terminating Party may have in respect of the event giving rise to the termination or any other right to damages or other remedy which either Party may have in respect of any breach of this Agreement which existed at or before the date of termination;
