8.8.8undertake such other tasks as may be necessary or desirable with respect to the calculation, implementation and reporting for United States Profit and Loss Share.

8.9Taxes.

8.9.1General. Any amounts due to be paid to a Party (the “Recipient”) hereunder (each, a “Payment”) shall be paid free and clear of any and all taxes (which, for clarity, shall be the responsibility of the paying Party (the “Payor”)), except for any withholding taxes required by Applicable Law. Except as provided in this Section 8.9, Recipient shall be solely responsible for paying any and all taxes (other than withholding taxes required by Applicable Law to be deducted from Payments and remitted by Payor) levied on account of, or measured in whole or in part by reference to, any Payments it receives. Payor shall deduct or withhold from the Payments any taxes that it is required by Applicable Law to deduct or withhold. Notwithstanding the foregoing, if Recipient is entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it may deliver to Payor or the appropriate Governmental Authority (with the assistance of Payor to the extent that this is reasonably required and is requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding or to relieve Payor of its obligation to withhold such tax and Payor shall apply the reduced rate of withholding or dispense with withholding, as the case may be; provided that Payor has received evidence of Recipient’s delivery of all applicable forms (and, if necessary, its receipt of appropriate governmental authorization) at least [****] prior to the time that the Payments are due. If, in accordance with the foregoing, Payor withholds any amount, it shall pay to Recipient the balance when due, make timely payment to the proper taxing authority of the withheld amount and send to Recipient proof of such payment within [****] following such payment. In the event that a government authority retroactively determines that a payment made by Payor to Recipient pursuant to this Agreement should have been subject to withholding or similar (or to additional withholding or similar) taxes, and Payor remits such withholding or similar taxes to the government authority, including any interest and penalties that may be imposed thereon (together with the tax paid, the “Amount”), Payor will have the right (a) to offset the Amount against future payment obligations of Payor under this Agreement, (b) to invoice Recipient for the Amount (which shall be payable by Recipient within [****] of its receipt of such invoice) or (c) to pursue reimbursement of the Amount by any other available remedy.

8.9.2Gross Up. If either Party assigns this Agreement to an Affiliate or Third Party (the “Assigning Party”), sublicenses any rights granted to it hereunder or undergoes a Change of Control and, as a result of such assignment, sublicense or Change of Control, Payments made hereunder are subject to additional withholding tax, the Assigning Party shall be responsible for the resulting additional withholding taxes; provided, however, that if the non-Assigning Party derives a tax benefit (including through the use of foreign tax credit) determined on a with and without basis as a result of such additional withholding, then such non-Assigning Party shall promptly reimburse Assigning Party for the amount of such benefit; provided, further,

that the non-Assigning Party shall take all commercially reasonable actions necessary to obtain any tax benefit (including through the use of foreign tax credit) with respect to such additional withholding taxes and to defend such benefit in a tax audit; provided, further, that the amount of additional withholding tax shall be determined by taking into account the reduction in the rate of, or the elimination of, the withholding tax pursuant to a tax treaty to which the non-Assigning Party would be entitled had it claimed such benefit under the tax treaty. For purposes hereof, “tax benefit” shall mean any refund or credit of taxes to be paid or reduction in the amount of taxes which otherwise would be owed by the non-Assigning Party, as applicable, in each case computed at the highest marginal tax rates applicable to non-Assigning Party.

8.9.3Value Added Tax. Notwithstanding anything contained in Section 8.9.1 or Section 8.9.2, this Section 8.9.3 shall apply with respect to value added tax (“VAT”). All Payments are exclusive of VAT. If any VAT is chargeable in respect of any Payments, Payor shall pay VAT at the applicable rate in respect of any such Payments following the receipt of a VAT invoice in the appropriate form issued by Recipient in respect of those Payments, such VAT to be payable on the later of the due date of the payment of the Payments to which such VAT relates and [****] after the receipt by Payor of the applicable invoice relating to that VAT payment, but Payor shall not reduce any Payment for the payment of VAT. If the VAT originally paid or otherwise borne by Payor are in whole or in part subsequently determined not to have been chargeable, all necessary steps will be taken by Recipient to receive a refund of the undue VAT from the applicable Governmental Authority or other fiscal authority and any amount of undue VAT repaid by such authority to Recipient will be transferred to Payor within [****] of receipt.

8.10Interest on Late Payments. If any payment due to either Party under this Agreement is not paid when due, then such paying Party shall pay interest thereon (before and after any judgment) at an annual rate (but with interest accruing on a daily basis) of [****] (or the maximum allowed by Applicable Law, if less), such interest to run from the date on which payment of such sum became due until payment thereof in full together with such interest.

8.11Financial Records. Without limitation of Section 8.5.1, each Party shall, and shall cause its Affiliates and require its and their Sublicensees to, keep complete and accurate financial books and records pertaining to the Development, Process Development, Manufacture and Commercialization of a Licensed Product hereunder, including books and records of [****], in sufficient detail to calculate and verify all amounts payable hereunder. Such books and records shall be retained by such Party and its Affiliates (and with respect to PARTNER, its Sublicensees) until the later of (a) [****] after the end of the period to which such books and records pertain, (b) [****] after the submission of any financial report to which such books and record pertain required to be made to the other Party under this Agreement or to a Third Party Licensor under an applicable Third Party License Agreement, (c) the expiration of the applicable tax statute of limitations (or any extensions thereof) and (d) for such period as may be required by Applicable Law.

8.12Audit. At the request of the other Party, the GSK Licensor or the Penn Licensor, each Party shall, and shall cause its Affiliates to (and in the case of PARTNER, shall require its Sublicensees to), permit an independent public accounting firm of nationally recognized standing designated by the other Party and reasonably acceptable to the audited Party, [****], to audit the books and records maintained pursuant to Section 8.11 to ensure the accuracy of all

reports and payments made hereunder. Such examinations may not (a) be conducted for any [****], (b) be conducted more than once in any [****] period (unless a previous audit during such [****] period revealed an underpayment with respect to such period) or (c) be repeated for any [****]. The accounting firm shall disclose to the auditing Party only whether the reports are correct or not, and the specific details concerning any discrepancies. No other information shall be shared. Except as provided below, the cost of this audit shall be borne by the auditing Party, unless the audit reveals a variance of more than [****] from the reported amounts or [****], in which case the audited Party shall bear the cost of the audit. Unless disputed pursuant to Section 8.13 below, if such audit concludes that (x) additional amounts were owed by the audited Party, the audited Party shall pay the additional amounts, with interest from the date originally due as provided in Section 8.10, or (y) excess payments were made by the audited Party, the auditing Party shall reimburse such excess payments, in either case ((x) or (y)), within [****] after the date on which such audit is completed by the auditing Party.

8.13Audit Dispute. In the event of a dispute with respect to any audit under Section 8.12, REGENX and PARTNER shall work in good faith to resolve the disagreement. If the Parties are unable to reach a mutually acceptable resolution of any such dispute within [****], the dispute shall be submitted for resolution to a certified public accounting firm jointly selected by each Party’s certified public accountants or to such other Person as the Parties shall mutually agree (the “Auditor”). The decision of the Auditor shall be final and the costs of such arbitration as well as the initial audit shall be borne between the Parties in such manner as the Auditor shall determine.

9.10.5Expenses and Recovery. [****].

9.10.6Third Party Control of Enforcement. Notwithstanding anything to the contrary herein, the rights and obligations under this Section 9.10 are subject to [****].

9.10.7Cooperation. For purposes of this Section 9.10, the Party prosecuting any infringement with respect to a Patent shall be the “Enforcing Party.” The Parties will cooperate fully in any infringement action pursuant to this Section 9.10, including by making the inventors, applicable records and documents (including laboratory notebooks) with respect to the relevant Patents enforceable under this Section 9.10 and available to the Enforcing Party at the Enforcing Party’s request. With respect to an action controlled by the applicable Enforcing Party, the other Party shall, and shall cause its Affiliates to, assist and cooperate with the Enforcing Party, as the Enforcing Party may reasonably request from time to time, in connection with its activities set forth in this Section 9.10, including where necessary, furnishing a power of attorney solely for such purpose or joining in, or being named as a necessary party to, such action, providing access

to relevant documents and other evidence and making its employees available at reasonable business hours; [****].

(i) Subject to this Section 9.10, including Sections 9.10.2, 9.10.3, 9.10.4 and 9.10.6, PARTNER shall have the right, but not the obligation, to prosecute, manage and settle any litigation with respect to Biosimilar Products in the Licensed Field and the Territory and any proceedings associated therewith, in connection with any Patents, including any invalidity, unpatentability or unenforceability challenges, oppositions and post-grant proceedings in connection therewith. If either Party receives a notice or a copy of an application submitted to the FDA or its foreign counterpart for a Biosimilar Product (a “Biosimilar Application”) for which a Licensed Product is a “reference product” as such term is used in Section 351(i)(4) of the PHSA, or an equivalent under its foreign counterpart, whether or not such notice or copy is provided under any Applicable Laws, or otherwise becomes aware that such a Biosimilar Application has been submitted to a Regulatory Authority for Regulatory Approval, such Party shall, within [****], notify the other Party and provide the other Party with copies of such notice or communication to the extent permitted by Applicable Law. PARTNER shall carry out any such rights and responsibilities of the “reference product sponsor,” as defined in Section 351(l)(1)(A) of the PHSA, for purposes of such Biosimilar Application, provided that PARTNER’s rights to bring an action for patent Infringement under Section 351(l)(6) of the PHSA based on any REGENX Patents, Collaboration Patents or Joint Patents are subject to REGENX’s applicable sole or first rights to bring an action for patent Infringement under Sections 9.10.3 and 9.10.4, and to the rights of the applicable REGENX Licensors and the limitations imposed on REGENX, its Affiliates and its and their respective sublicensees that are set forth in the applicable Third Party License Agreements. The Parties shall cooperate seeking to obtain access to the Biosimilar Application and related confidential information, including in accordance with Section 351(l)(1)(B)(iii) of the PHSA, if applicable. If permitted pursuant to Applicable Law, upon one Party’s request, the other Party shall assist the requesting Party in identifying and listing any and all relevant Patents pursuant to Section 351(l)(1)(3)(A) or Section 351(l)(7) of the PHSA, in preparing, pursuant to section 351(l)(3)(C) of the PHSA, a detailed statement regarding the reference product sponsor’s opinion that any such Patent will be infringed and a response to the statement by the filer of the Biosimilar Application concerning validity and enforceability, in negotiating with the filer of the Biosimilar Application pursuant to Section 351(l)(4) of the PHSA, and in selecting Patents enforceable under this Section 9.10 for and conducting litigation pursuant to Section 351(l)(5), Section 351(l)(6), and Section 351(l)(9) of the PHSA, to the extent applicable, and shall cooperate with the requesting Party in responding to relevant communications with

respect to such lists and statements from the filer of the Biosimilar Application. The Parties shall cooperate and assist each other in seeking an injunction against any commercial marketing by the filer of a Biosimilar Application as permitted pursuant to Section 351(l)(8)(B) of the PHSA or in filing an action for infringement against the filer of such Biosimilar Application.

9.11Defense of Infringement Claims. In the event PARTNER or REGENX becomes aware that PARTNER’s or any of its Affiliates’ or any Sublicensees’ Exploitation of the Licensed Product in the Licensed Field is the subject of a claim for patent infringement by a Third Party, that Party shall promptly notify the other Party, [****]. Unless the Party against whom a Third Party infringement claim is filed seeks indemnification for such claim covered pursuant to ARTICLE 12, subject to compliance with the provisions of this Section 9.11, the alleged infringing Party shall have the sole right, but not the obligation, to defend and control the defense of any such claim, suit or proceeding. Without limitation of the foregoing, if the alleged infringing Party finds it necessary or desirable to join the other Party as a party to any such action, the other Party shall execute all papers and perform such acts as shall be reasonably required. Each Party shall keep the other Party reasonably informed of all material developments in connection with any such claim, suit, or proceeding. [****]. Notwithstanding anything to the contrary herein, the rights and obligations under this Section 9.11 are subject to the rights of the applicable REGENX Licensors and the limitations imposed on REGENX, its Affiliates and its and their respective sublicensees that are set forth in the applicable Third Party License Agreements and the alleged infringing Party shall not settle or compromise any claim for patent infringement (including related defensive claims and counterclaims) under this Section 9.11 with respect to any Patent [****].

9.12Invalidity or Unenforceability Defenses or Actions.

9.12.1Notice. Each Party shall promptly notify the other Party in writing of any alleged or threatened assertion of invalidity, unpatentability or unenforceability of any of the REGENX Patents, PARTNER Patents, or Joint Patents by a Third Party, in each case in the Territory and of which such Party becomes aware. Notwithstanding anything to the contrary herein, the rights and obligations under this Section 9.12 are subject to the rights of the applicable REGENX Licensors and the limitations imposed on REGENX, its Affiliates and its and their respective sublicensees that are set forth in the applicable Third Party License Agreements.

9.12.2Defense of Patents. Subject to the terms and conditions of this Agreement, the Prosecuting Party shall have the first right, but not the obligation, to defend and control the defense of the validity, patentability and enforceability of the Patents being Prosecuted by such Prosecuting Party under this Section 9.12 in the Territory. The non-Prosecuting Party may participate in any such claim, suit, or proceeding in the Territory with counsel of its choice at its own expense; provided that the Prosecuting Party shall retain control of the defense in such claim, suit, or proceeding. If the Prosecuting Party elects not to defend or control the defense of such Patent (other than a PARTNER Patent) in a claim, suit or proceeding brought in the Territory, or otherwise fails to initiate and maintain the defense of any such claim, suit, or proceeding, then the non-Prosecuting Party may become the controlling Party and conduct and control the defense of any such claim, suit, or proceeding.

9.12.3Cooperation. Each Party shall assist and cooperate with the other Party as such other Party may reasonably request from time to time in connection with its

activities set forth in this Section 9.12, including by being joined as a necessary party in such claim, suit or proceeding, providing access to relevant documents and other evidence, and making its employees available at reasonable business hours. In connection with any such defense or claim or counterclaim, the controlling Party shall consider in good faith any comments from the other Party and shall keep the other Party reasonably informed of any material steps taken. Subject to the other terms and conditions of this Agreement, the controlling Party shall have the right to settle such claim, suit or proceeding under this Section 9.12, provided that the controlling Party shall not settle any such claim, suit or proceeding in a manner that imposes any out-of-pocket costs or liability on, or involves any admission by, the other Party, without the express written consent of such other Party. Furthermore, the controlling Party shall not settle or compromise any such claim, suit or proceeding under this Section 9.12 with respect to any Patent in a manner that imposes any obligations or other restrictions on an applicable REGENX Licensor, or that has a material adverse effect on the validity, scope of patent claims, or enforceability of any of the GSK Patents, or grants any rights to the GSK Patents, other than any permitted sublicenses, without the applicable REGENX Licensor’s prior written permission as set forth in the applicable Third Party License Agreements. [****].

9.13Third Party Patent Rights. If in the reasonable opinion of either Party, a license under any Patent or other intellectual property right of a Third Party in any country in the Territory is necessary or reasonably useful to Exploit the Licensed Product for use in the Licensed Field in the Territory in accordance with this Agreement (such right, a “Third Party Patent Right”), then the Parties shall meet and discuss the strategy for obtaining such Third Party Patent Right. The Parties shall negotiate in good faith to reach agreement with respect to such strategy. If no agreement has been reached after [****] following commencement of such discussions, then [****]. If either Party determines not to enter into such an agreement under the foregoing clauses (a) or (b), then it shall promptly notify the other Party thereof, and the other Party shall thereafter have the right to enter into such an agreement. Each Party shall ensure that any such license entered into under this Section 9.13 shall be freely sublicensable to the other Party and its Affiliates to enable such other Party and its Affiliates to fully exercise its rights and perform its obligations under this Agreement and shall promptly provide the other Party with a copy of any Third Party agreement entered into under this Section 9.13 with redactions permitted to the extent not reasonably necessary for the other Party to understand its obligations under such agreement or such agreement’s relevance to this Agreement. If the grant of a sublicense under a Third Party agreement entered into by either Party under this Section 9.13 would result in the other Party having any different or additional obligations or being subject to any additional terms as a result of being a sublicensee under such agreement, the other Party shall have [****] after receipt of a copy of such agreement to notify the Party that entered into the Third Party agreement as to whether it accepts such sublicensed rights. Notwithstanding anything to the contrary in this Agreement, unless and until the other Party notifies the Party that entered into the Third Party agreement within such [****] period that it wishes to receive a sublicense under the Third Party agreement entered into under this Section 9.13, Information and Patents licensed by the Party that entered into the Third Party agreement from a Third Party will not be deemed “Controlled” by the Party that entered into the Third Party agreement or its Affiliates under this Agreement and the other Party shall not be granted any rights, or have any obligations, under such Third Party agreement. [****]. If in the reasonable opinion of PARTNER, a Third Party Patent Right may relate to the Exploitation of a Licensed Product by PARTNER or its Affiliates, then PARTNER or its Affiliates shall have the sole right, but not the obligation, to challenge the patentability,

validity or enforceability of such Patent in any court of competent jurisdiction or before any supra-national, federal, national, regional, state, provincial and local governmental body of competent jurisdiction including the United States Patent and Trademark Office and the European Patent Office. REGENX shall not challenge the patentability, validity or enforceability of such Patent in any court or governmental body without PARTNER’s prior written consent, provided, however, that notwithstanding the foregoing, REGENX will not be prevented from challenging the patentability, validity or enforceability of any such Third Party Patent Right to the extent unrelated to the Licensed Product and the Indications in the Licensed Field. REGENX shall assist and cooperate with PARTNER as PARTNER may reasonably request from time to time in connection with the activities set forth in this Section 9.13.

9.14International Nonproprietary Name. As between the Parties, PARTNER shall have the sole right and responsibility to select the International Nonproprietary Name or other name or identifier for any Licensed Product. PARTNER shall have the sole right and responsibility to apply for submission to the World Health Organization for the International Nonproprietary Name , and submission to the United States Adopted Names Council for the United States Adopted Name.

9.15Product Trademarks. PARTNER shall be responsible for the registration, prosecution, and maintenance of the Product Trademarks using counsel of its own choice. PARTNER shall have the sole right and responsibility to take such action as PARTNER reasonably deems necessary against a Third Party based on any alleged, threatened or actual infringement, dilution, misappropriation or other violation of or unfair trade practices or any other like offense relating to, the Product Trademarks by a Third Party using counsel of its own choice. PARTNER shall have the sole right and responsibility to defend against and settle any alleged, threatened or actual claim by a Third Party that the use or registration of the Product Trademarks in the Territory infringes, dilutes, misappropriates or otherwise violates any Trademark or other right of that Third Party or constitutes unfair trade practices or any other like offense or any other claims as may be brought by a Third Party against a Party in connection with the use of the Product Trademarks with respect to the Licensed Product for use in the Licensed Field in the Territory using counsel of its choice. [****].

12.2Indemnification of PARTNER. REGENX shall indemnify PARTNER, its Affiliates, and its and their respective directors, officers, employees and agents (collectively, “PARTNER Indemnitees”) and defend and save each of them harmless, from and against any and all Losses to which any PARTNER Indemnitee becomes subject as a result of any and all Third Party Claims arising from or occurring as a result of: [****], except, [****], for those Losses for which PARTNER has an obligation to indemnify REGENX pursuant to Section 12.1 hereof, as to which Losses each Party shall indemnify the other to the extent of their respective liability for the Losses.

In the absence of such an agreement, each Party shall have the right to take such action as it deems appropriate.

12.4Indemnification Procedures.

12.4.1Notice of Claim. All indemnification claims in respect of a REGENX Indemnitee or PARTNER Indemnitee shall be made solely by REGENX or PARTNER, respectively (the “Indemnified Party”). The Indemnified Party shall give the indemnifying Party prompt written notice (an “Indemnification Claim Notice”) of any Losses or discovery of fact upon which such Indemnified Party intends to base a request for indemnification under this ARTICLE 12, but in no event shall the indemnifying Party be liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party shall furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims.

12.4.2Control of Defense. The indemnifying Party shall have the right to assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within [****] after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying Party shall not be construed as an acknowledgment that the indemnifying Party is liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor shall it constitute a waiver by the

indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party; provided that it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed). In the event that the indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall immediately deliver to the indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, except as provided in Section 12.4.3, the indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim unless specifically requested in writing by the indemnifying Party.

12.4.4Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Third Party Claim and that shall not result in the applicable indemnitee(s) becoming subject to injunctive or other relief or otherwise adversely affecting the business of the Indemnified Party in any manner and as to which the indemnifying Party shall have acknowledged in writing the obligation to indemnify the applicable indemnitee hereunder, the indemnifying Party shall have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, shall deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 12.4.2, the indemnifying Party shall have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss; provided that it obtains the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed). If the indemnifying Party does not assume and conduct the defense of a Third Party Claim as provided above, the Indemnified Party may defend against such Third Party Claim; provided that the Indemnified Party shall not settle any Third Party Claim without the prior written consent of the indemnifying Party (which consent shall not be

unreasonably withheld, conditioned or delayed).

12.4.5Cooperation. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party shall and shall cause each indemnitee to, cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim and making indemnitees and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder and the indemnifying Party shall reimburse the Indemnified Party for all its, its Affiliates’ and its and their (sub)licensees’ or their respective directors’, officers’, employees’ and agents’, as applicable, reasonable and verifiable out-of-pocket expenses in connection therewith.

12.4.6Expenses. Except as provided above, the costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party and its Affiliates and its and their (sub)licensees and their respective directors, officers, employees and agents, as applicable, in connection with any claim shall be reimbursed on a [****] basis by the indemnifying Party, without prejudice to the indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

13.2.2Material Breach.

(a)Breach Notice. If either Party (the “Non-Breaching Party”) believes that the other Party (the “Breaching Party”) is in Material Breach, then in addition to any other right and remedy the Non-Breaching Party may have, the Non-Breaching Party may deliver notice of such Material Breach to the Breaching Party that specifies the breach and its claim of right to terminate (the “Termination Notice”). With regard to any Material Breach by PARTNER that constitutes a material breach under the GSK Agreement, PARTNER shall have [****] (the “GSK Notice Period”) following the receipt of such Termination Notice to cure such Material Breach.

(b)Disputes Regarding Material Breach. In each case other than with regard to a sublicense granted by REGENX to PARTNER under the Penn Agreement or

the GSK Agreement, the Breaching Party may dispute occurrence of such Material Breach, and in such case the Breaching Party shall give written notice of such dispute no later than [****] after its receipt of the Termination Notice and the issue of whether the Non-Breaching Party may properly terminate this Agreement on expiration of the applicable cure period will be resolved in accordance with Section 14.5. If as a result of such dispute resolution process, it is determined that the Breaching Party committed a Material Breach and the Breaching Party does not cure such Material Breach within (i) [****] in the case of a failure to make a payment set forth in this Agreement or (ii) [****] in the case of any other Material Breach, as applicable, after the date of such determination, (the “Additional Cure Period”), then such termination will be effective as of the expiration of the Additional Cure Period. Except for [****], this Agreement will remain in full force and effect during the pendency of any such dispute resolution proceeding and the cure periods set forth in this Section 13.2.2, and any Additional Cure Period, in each case, will be tolled during any such dispute resolution proceeding, such proceeding will not suspend any obligations of either Party hereunder, and each Party will use reasonable efforts to mitigate any damage. If as a result of such dispute resolution proceeding it is determined that the Breaching Party did not commit such Material Breach (or such Material Breach was cured in accordance with this Section 13.2.2), then no termination will be effective, and this Agreement will continue in full force and effect. With regard to any sublicense granted by REGENX to PARTNER under the Penn Agreement or the GSK Agreement, [****].
