such transaction, at the time of the transaction, assuming an arm’s length transaction made in the ordinary course of business, as determined jointly and in good faith by Licensor and Licensee based on transactions of a similar type and standard industry practice, if any.

3.8.4 To the extent Licensee or its Affiliates receives payment from a Third Party relating to one or more of the milestone events set forth in the tables in Section 3.6, then the amount of the payment made to Licensor under such Section 3.6 with respect to such milestone event shall not be deemed sublicense fees under this Section 3.8; instead, the amounts due under this Section 3.8 shall be calculated by applying the applicable sublicense fee rate set forth in Section 3.8.1 above to the sublicense fees received by Licensee or its Affiliates from such Third Party after deducting the amount of the payment under Section 3.6.

At the request of Licensee, Licensor will give Licensee such reasonable assistance, which will include the provision of documentation as may be required by the

relevant tax authority, to enable Licensee to pay and report and, as applicable, claim exemption from or reduction of, such tax, duty, levy, fee, or charge.

At the request of Licensor, Licensee will give Licensor such reasonable assistance, which will include the provision of appropriate certificates of such deductions made together with other supporting documentation as may be required by the relevant tax authority, to enable Licensor to claim exemption from or reduction of, or otherwise obtain repayment of, such withholding taxes, and will upon request provide such additional documentation from time to time as is reasonably required to confirm the payment of withholding tax.

4.1.1 Licensed Product Diligence Obligations. Licensee will use commercially reasonable efforts to develop, commercialize, market, promote, and sell Licensed Products in the AATD Field. Furthermore, if Licensee exercises the Indication Option granted to Licensee under Section 2.2, Licensee will use commercially reasonable efforts to develop, commercialize, market, promote, and sell Licensed Products in the Option Field for which Licensee exercised an Indication Option.

4.2.6 Summary of significant development efforts using the Licensed Patents being performed by Third Parties, including the nature of the relationship between Licensee and such Third Parties.

4.3Development Plans. Following receipt by Licensor of each development plan, Licensor will promptly notify Licensee of any comments or requested revisions, and the Parties will thereupon negotiate any appropriate revisions in good faith.

4.4Confidential Information. The Parties agree that Development Progress Reports shall be deemed Licensee’s Confidential Information; provided that Licensor may share a copy of such reports with the REGENX Licensors under confidentiality.

4.5Improvements. Simultaneously with the Development Progress Report, Licensee shall deliver a detailed description of any Licensee Inventions and any Licensed Back Improvements, if not previously provided pursuant to Section 2.7.3, which shall be Licensee’s Confidential Information.

5.1Treatment of Confidential Information. Each Party, as a receiving party (a “Receiving Party”), agrees that it will (a) treat Confidential Information received by or on behalf of the other Party under this Agreement (the “Disclosing Party”) as strictly confidential; (b) not disclose such Confidential Information to Third Parties without the prior written consent of the Disclosing Party, except as may be permitted in this Agreement; provided that any disclosure permitted hereunder shall be under confidentiality agreements with provisions at least as stringent as those

contained in this Agreement; and (c) not use such Confidential Information for purposes other than those authorized expressly in this Agreement. The Receiving Party agrees to ensure that its employees who have access to Confidential Information are obligated in writing to abide by confidentiality obligations at least as stringent as those contained under this Agreement.

5.2.1 The Parties agree they will release a joint press release in the form attached hereto as Exhibit B. Except as provided in Section 5.2.2, any other press releases by either Party with respect to the other Party or any other public disclosures concerning the existence of or terms of this Agreement shall be subject to review and approval by the other Party. Once the joint press release or any other written statement is approved for disclosure by both Parties, either Party may make subsequent public disclosure of the contents of such statement without the further approval of the other Party.

5.2.2 Notwithstanding Section 5.2.1, Licensor has the right to publish (through press releases, scientific journals, or otherwise) and refer to any clinical, regulatory, or research results related to Licensee’s Licensed Product that have been publicly disclosed by Licensee, including referring to Licensee by name as a licensee of Licensor, which publication or referral by Licensor shall not require the prior consent of Licensee, but Licensor will provide Licensee with a copy of any such publications or referrals two business days prior to release.

5.3Authorized Disclosure. Notwithstanding the provisions of Section 5.1 or 5.2, either Party may disclose the other’s Confidential Information or make such a disclosure of the existence of and/or terms of this Agreement to any [***]; provided that, in each case, such recipient of Confidential Information is obligated to keep such information confidential on terms no less stringent than those set forth in this Agreement. Furthermore, Licensee agrees that Licensor may share a copy of this Agreement, reports and notices provided by Licensee to Licensor pursuant to the terms of this Agreement, and copies of sublicense agreements provided to Licensor hereunder, with the REGENX Licensors to the extent required by the GSK Agreement and Penn Agreement, under confidentiality. In the event that the Receiving Party receives service of legal process that purports to compel disclosure of the Disclosing Party’s Confidential Information or becomes obligated by law, rule, regulation or rules of a securities exchange to disclose the Confidential Information of the Disclosing Party or the existence of or terms of this Agreement to any governmental authority, then, to the extent legally permitted, the Receiving Party shall promptly notify the Disclosing Party, so that the Disclosing Party may seek an appropriate protective order or other remedy with respect to narrowing the scope of such requirement and/or waive compliance by the Receiving Party with the provisions of this Agreement. The Receiving Party will, at the Disclosing Party’s request and expense, provide the Disclosing Party with reasonable assistance in obtaining such protective order or other remedy. If, in the absence of such protective order or other remedy, the Receiving Party is nonetheless required by law, rule, regulation or rules of a securities exchange to disclose the existence of or terms of this Agreement or other Confidential Information of the Disclosing Party, the Receiving Party may disclose such Confidential Information without liability hereunder; provided that the Receiving Party shall furnish only such portion of the Confidential Information that is legally required to be disclosed and only to the extent required by law.

6.4.1 Licensor may terminate this Agreement, if Licensee is late in paying to Licensor royalties, fees, or any other monies due under this Agreement, and Licensee does not pay Licensor in full within fifteen (15) days upon written demand from Licensor, which termination shall be effective immediately upon the expiration of such fifteen (15)-day cure period.

6.7.2 At Licensor’s request, Licensee shall assign to Licensor any or all sublicenses granted to Third Parties to the extent of the rights licensed to Licensee hereunder and sublicensed to the Sublicensee unless the Sublicensee notifies Licensor in writing that the Sublicensee does not wish such sublicense to be so assigned (in which case such sublicense shall terminate); provided that (i) prior to such assignment, Licensee shall advise Licensor whether such Sublicensee is then in full compliance with all terms and conditions of its sublicense and continues to perform thereunder, and, if such Sublicensee is not in full compliance or is not continuing to perform, Licensor may elect not to have such sublicense assigned; and (ii) following such assignment, Licensor shall not be liable to such Sublicensee with respect to any obligations of Licensee to the Sublicensee that are not consistent with, or not required by, Licensor’s obligations to Licensee under this Agreement; and all sublicenses not requested to be assigned to Licensor shall terminate;

6.7.3 If termination is by Licensee pursuant to Section 6.3 or by Licensor pursuant to Section 6.4, 6.5 or 6.6, Licensee shall grant, and hereby grants to Licensor a non-exclusive, perpetual, irrevocable, worldwide, royalty-free, transferable, sublicensable license under any patentable modifications or improvements (and any intellectual property rights with respect thereto) developed by Licensee or any Affiliates (during the term of and pursuant to this Agreement) or by any Sublicensees (during the term of and pursuant to any sublicense agreement with such Sublicensee) to any vector that is the subject of a claim within any of the Licensed Patents, for use by Licensor for the research, development, and commercialization of products in any therapeutic indication;

6.8Survival. Licensee’s obligation to pay all monies due and owed to Licensor under this Agreement which have matured as of the effective date of termination or expiration shall survive the termination or expiration of this Agreement.

7.1Prosecution of Licensed Patents. As between Licensor and Licensee, but subject to any obligations of Licensor to the REGENX Licensors, the Parties agree as follows:.

7.1.1 Licensor shall have the sole right, but not the obligation, to Prosecute patent applications and issued patents within Licensed Patents, in Licensor’s sole discretion.

7.1.2 Nothing in this Agreement obligates Licensor to continue to Prosecute any patent applications or issued patents, and Licensee acknowledges that Licensor shall have no obligation to undertake any inter-party proceedings, such as oppositions or interferences, or to undertake any re-examination or re-issue proceedings, in either case, with respect to the Licensed Patents.

7.2.1 Licensee is responsible for notifying the Licensor promptly of any infringement of Licensed Patents (other than Retained Rights) that may come to Licensee’s attention, including any “patent certification” filed in the United States under 21 U.S.C. § 355(b)(2) or 21 U.S.C. § 355(j)(2) or similar provisions in other jurisdictions alleging the invalidity, unenforceability or non-infringement of any Licensed Patents, and any notification received pursuant to subsection (k) of 42 U.S.C. § 262 for any Licensed Product that becomes a “reference product.”

7.2.2 As between Licensor and Licensee, but subject to any obligations of Licensor to the REGENX Licensors, Licensor shall have the sole right, but not the obligation, to prosecute any such infringement at its [***] recovered in connection therewith. In any action to enforce any of the Licensed Patents, Licensee, at the request and expense of Licensor, shall cooperate to the fullest extent reasonably possible, including in the event that, if Licensor is unable to initiate or prosecute such action solely in its own name, Licensee shall join such action voluntarily and shall execute all documents necessary to initiate litigation to prosecute, maintain, and settle such action. Nothing in this Agreement obligates Licensor to bring or prosecute lawsuits against Third Parties for infringement of any Licensed Patents.

7.2.3 Licensee shall have no right to undertake prosecution of any such infringement.

7.3Defense of Infringement Claims. In the event Licensee or Licensor becomes aware that Licensee’s or any of its Affiliates’ or any Sublicensees’ practice of the Licensed Patents is the subject of a claim for patent infringement by a Third Party, that Party shall promptly notify the other, and the Parties shall consider the claim and the most appropriate action to take. Licensee shall cause each of its Affiliates and each Sublicensee to notify Licensee promptly in the event such entity becomes aware that its practice of the Licensed Patents is the subject of a claim of patent infringement by another. To the extent Licensor takes any action, Licensor (or the REGENX Licensors) shall have the right to require Licensee’s reasonable cooperation in any such suit, upon written notice to Licensee; and Licensee shall have the obligation to participate upon Licensor’s request, in which event, Licensor shall bear the cost of Licensee’s participation. Without Licensor’s prior written permission, Licensee must not settle or compromise any such suit in a manner that imposes any material obligations or restrictions on Licensor or the REGENX Licensors or grants any rights to the Licensed Patents other than rights that Licensee has the right to grant under this Agreement.

8.1Representations and Warranties by Licensor. Licensor represents and warrants to Licensee as of the Effective Date:

8.1.1 Licensor has the right, power, and authority to enter into this Agreement and to grant to Licensee the licenses specified in this Agreement;

8.1.2 This Agreement when executed shall become the legal, valid, and binding obligation of it, enforceable against it, in accordance with its terms.

8.1.4 To Licensor’s knowledge, (a) the Licensed Patents are solely owned by the Trustees of the University of Pennsylvania, and (b) no Third Party (other than REGENX Licensors) has any right, interest, or claim in or to such Licensed Patents with respect to the AATD Field or the Option Field that are inconsistent with those granted to Licensee with respect to the AATD Field or the Option Field;

8.1.5 To Licensor’s knowledge, no Third Party is infringing any of the Licensed Patents in a manner that is inconsistent with the scope of rights granted to Licensee with respect to the AATD Field or the Option Field; and

8.1.6 Licensor has not received any written notice from any Third Party patentee alleging infringement of such Third Party’s patents by the practice of the Licensed Patents with respect to the AATD Field or the Option Field.

8.2Representations and Warranties by Licensee. Licensee represents and warrants to Licensor as of the Effective Date that:

8.2.1 Licensee has the right, power, and authority to enter into this Agreement and to grant the licenses granted by it hereunder;

8.2.3 Licensee has the ability and the resources, including financial resources, necessary to carry out its obligations under this Agreement.

8.2.4 There are no actions, suits, proceedings, or arbitrations pending or, to Licensee’s knowledge, threatened against Licensee that would impact activities under this Agreement; and

8.2.5 Licensee is not, in any material respect, in violation or default of any provision of its certificate of incorporation or its bylaws.

8.3Disclaimer of Warranties, Damages. EXCEPT AS SET FORTH IN SECTION 8.1, THE LICENSED PATENTS, LICENSED PRODUCTS, AND ALL RIGHTS LICENSED UNDER THIS AGREEMENT ARE PROVIDED ON AN “AS IS” BASIS, AND LICENSOR MAKES NO REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, WITH RESPECT THERETO. BY WAY OF EXAMPLE BUT NOT OF LIMITATION, EXCEPT AS EXPRESSLY SET FORTH IN SECTION 8.1, LICENSOR MAKES NO REPRESENTATIONS OR WARRANTIES, AND HEREBY DISCLAIMS ALL EXPRESS AND IMPLIED REPRESENTATIONS AND WARRANTIES, (i) OF COMMERCIAL UTILITY, ACCURACY, COMPLETENESS, PERFORMANCE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, VALIDITY OR ENFORCEABILITY OF THE LICENSED PATENTS, AND PROFITABILITY; OR (ii) THAT THE USE OF THE LICENSED PATENTS OR LICENSED PRODUCTS WILL NOT INFRINGE ANY PATENT, COPYRIGHT,

TRADEMARK, OR OTHER PROPRIETARY RIGHTS OF THIRD PARTIES. EXCEPT AS SET FORTH HEREIN, NONE OF LICENSOR OR EITHER OF THE REGENX LICENSORS SHALL BE LIABLE TO LICENSEE, LICENSEE’S SUCCESSORS OR ASSIGNS, ANY SUBLICENSEES, OR ANY THIRD PARTY WITH RESPECT TO: (a) ANY CLAIM ARISING FROM USE OF THE LICENSED PATENTS, LICENSED PRODUCTS, AND ANY OR ALL RIGHTS LICENSED UNDER THIS AGREEMENT OR FROM THE DEVELOPMENT, TESTING, MANUFACTURE, USE, OR SALE OF LICENSED PRODUCTS; OR (b) ANY CLAIM FOR LOSS OF PROFITS, LOSS OR INTERRUPTION OF BUSINESS, OR FOR INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL DAMAGES OF ANY KIND, INCLUDING ANY ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT OR THE EXERCISE OF RIGHTS HEREUNDER, REGARDLESS OF ANY NOTICE OF SUCH DAMAGES. NOTHING IN THIS SECTION 8.3 IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY UNDER SECTION 8.4 OR TO LIMIT A PARTY’S LIABILITY FOR BREACHES OF ITS OBLIGATION REGARDING CONFIDENTIALITY UNDER ARTICLE 5.

8.4.1 By Licensee. Licensee shall defend, indemnify, and hold harmless Licensor, the REGENX Licensors, and their respective shareholders, members, officers, trustees, faculty, students, contractors, agents, and employees (individually, a “Licensor Indemnified Party” and, collectively, the “Licensor Indemnified Parties”) from and against any and all Third Party liability, loss, damage, action, claim, fee, cost, or expense (including attorneys’ fees) (individually, a “Third Party Liability” and, collectively, the “Third Party Liabilities”) suffered or incurred by the Licensor Indemnified Parties from claims of such Third Parties to the extent that such claims result from or arise out of: [***]; provided, however, that Licensee shall not be liable for claims to the extent based on (1) any breach by Licensor of the representations, warranties, or obligations of Licensor under this Agreement or (2) the gross negligence or intentional misconduct of any of the Licensor Indemnified Parties. Without limiting the foregoing, but subject to clauses (1) and (2) above, Licensee must defend, indemnify, and hold harmless the Licensor Indemnified Parties from and against any Third Party Liabilities resulting from:

8.4.2 By Licensor. Licensor shall defend, indemnify, and hold harmless Licensee, its shareholders, members, officers, contractors, agents, and employees (individually, a “Licensee

Indemnified Party” and, collectively, the “Licensee Indemnified Parties”) from and against any and all Third Party Liabilities suffered or incurred by the Licensee Indemnified Parties from claims of such Third Parties to the extent that such claims result from or arise out of: [***]; provided, however, that Licensor shall not be liable for claims to the extent based on (1) any breach by Licensee of the representations, warranties, or obligations of Licensee under this Agreement or (2) the gross negligence or intentional misconduct of any of the Licensee Indemnified Parties.

8.4.3 Indemnification Procedure. Each Party, as an indemnifying party (an “Indemnifying Party”), shall not be permitted to settle or compromise any claim or action giving rise to Third Party Liabilities in a manner that imposes any restrictions or obligations on any indemnified party (an “Indemnified Party”) without the Indemnified Party’s prior written consent or, if Licensee is the Indemnifying Party, that imposes any restrictions or obligations on Licensor’s direct or indirect licensors or grants any rights to the Licensed Patents or Licensed Products other than those Licensee has the right to grant under this Agreement without Licensor’s prior written consent. The Indemnifying Party shall be permitted to control any litigation or potential litigation involving the defense of any claim subject to indemnification pursuant to this Section 8.4, including the selection of counsel, with the reasonable approval of the Indemnified Party. Upon the Indemnifying Party’s reasonable request, the Indemnified Parties will reasonably cooperate with the Indemnifying Party in the defense and settlement of any such claim, at the Indemnifying Party’s cost and expense. If an Indemnifying Party fails or declines to assume the defense of any such claim or action within [***] after notice thereof, the Indemnified Party may assume the defense of such claim or action at the cost and risk of the Indemnifying Party, and any Third Party Liabilities related thereto shall be conclusively deemed a Third Party Liability of the Indemnifying Party. The indemnification rights of an Indemnified Party contained in this Agreement are in addition to all other rights that such Indemnified Party may have at law or in equity or otherwise. The Indemnifying Party will pay directly all Third Party Liabilities incurred for defense or negotiation of any claim hereunder or will reimburse the Indemnified Party for all documented Third Party Liabilities incident to the defense or negotiation of any such claim within [***] after the Indemnifying Party’s receipt of invoices for such fees, expenses, and charges.

8.5Insurance. Licensee will procure and maintain insurance policies for the following coverages with respect to product liability, personal injury, bodily injury, and property damage arising out of Licensee’s (and its Affiliates’ and any Sublicensees’) performance under this Agreement: (a) during the term of this Agreement, comprehensive general liability, including broad form and contractual liability, in a minimum amount of [***] combined single limit per occurrence (or claim) and in the aggregate annually; (b) prior to the commencement of clinical trials involving Licensed Products and thereafter for a period of not less than [***] (or such longer period as Licensee is required by applicable law to continue to monitor the participants in the clinical trial), clinical trials coverage in amounts that are reasonable and customary in the U.S. pharmaceutical industry, subject always to a minimum limit of $3,000,000 combined single limit per occurrence (or claim) and in the aggregate annually; and (c) from prior to the first commercial sale of a Licensed Product until [***] after the last sale of a Licensed Product, product liability coverage, in amounts that are reasonable and customary in the U.S. pharmaceutical industry, subject always to a minimum limit of [***] combined single limit per occurrence (or claim) and in the aggregate annually. Licensor may review periodically the

adequacy of the minimum amounts of insurance for each coverage required by this Section 8.5, and Licensor reserves the right to require Licensee to adjust the limits accordingly. The required minimum amounts of insurance do not constitute a limitation on Licensee’s liability or indemnification obligations to the Licensor Indemnified Parties under this Agreement. The policies of insurance required by this Section 8.5 will be issued by an insurance carrier with an A.M. best rating of [***] or better and will name Licensor as an additional insured with respect to Licensee’s performance (and its Affiliates’ and any Sublicensees’) under this Agreement. Licensee will provide Licensor with insurance certificates evidencing the required coverage within [***] after the Effective Date and the commencement of each policy period and any renewal periods. Each certificate will provide that the insurance carrier will notify Licensor in writing at least [***] prior to the cancellation or material change in coverage. Licensee will cause all Sublicensees to comply with the terms of this Section 8.5 to the same extent as Licensee.

Licensee, its Affiliates, any Sublicensees, and all of its and their employees and agents must not use Licensor’s, the University of Pennsylvania’s, or SmithKline Beecham Corporation’s name, seal, logo, trademark, or service mark (or any adaptation thereof) or the name, seal, logo, trademark, or service mark (or any adaptation thereof) of any of such entities’ representative, school, organization, employee, or student in any way without the prior written consent of Licensor or such entity, as applicable, unless required to do so pursuant to applicable law, rule, regulation or rules of a securities exchange; provided, however that Licensee may acknowledge the existence and general nature of this Agreement, subject to Section 5.2.1.

10.1Relationship. Nothing in this Agreement shall be deemed to establish a relationship of principal and agent between Licensee and Licensor, nor any of their agents or employees for any purpose whatsoever, nor shall this Agreement be construed as creating any other form of legal association or arrangement which would impose liability upon one Party for the act or failure to act of the other Party.

10.2 Assignment. The rights and obligations of Licensee and Licensor hereunder shall inure to the benefit of, and shall be binding upon, their respective permitted successors and assigns. Licensee may not assign or otherwise transfer (by operation of law or otherwise) this Agreement or any of its rights or obligations under this Agreement without the prior written consent of Licensor which consent is in the absolute discretion of Licensor; provided, however, Licensee shall be permitted to assign or otherwise transfer (by operation of law or otherwise ) this Agreement without Licensor’s consent, (a) to any Affiliate; or (b) in connection with a Change of Control; provided that, as part of any permitted assignment or transfer, Licensee: (i) requires any assignee, transferee, or successor to agree in writing to be legally bound by this Agreement to the same extent as Licensee and provides Licensor with a copy of such undertaking; (ii) provides Licensor with written notice of the assignment or transfer to Licensor within five (5) days of the consummation of the transaction resulting in the assignment or transfer; (iii) in the event of a Change of Control of Licensee, provides Licensor with redacted copies of the transaction documents resulting in a Change of Control of Licensee within five (5) days of the

consummation of the transaction; and (iv) in the event of an assignment or transfer to an Affiliate, remains responsible for the performance of this Agreement by such Affiliate. Notwithstanding anything to the contrary in this Agreement, for clarity, in case of a Licensee Change of Control, in no event shall any intellectual property rights owned or controlled by the acquirer or its Affiliates immediately prior to such Licensee Change of Control be included in any of the licenses granted to Licensor under this Agreement. Licensor may assign this Agreement and its rights and obligations without the consent of Licensee.

10.5 Applicable Law. This Agreement shall be construed and governed in accordance with the laws of the State of New York, without giving effect to conflict of law provisions that may require the application of the laws of another jurisdiction. Subject to Section 10.6, the Parties hereby submit to the exclusive jurisdiction of and venue in the courts located in the State of New York with respect to any and all disputes concerning the subject of this Agreement.

10.6.1 Arbitration. In the event of any controversy or claim arising out of or relating to this Agreement, the Parties shall first attempt to resolve such controversy or claim through good faith negotiations for a period of not less than thirty (30) days following notification of such controversy or claim to the other Party. If such controversy or claim cannot be resolved by means of such negotiations during such period, then such controversy or claim shall be resolved by binding arbitration administered by the American Arbitration Association (“AAA”) in accordance with the Commercial Arbitration Rules of the AAA in effect on the date of commencement of the arbitration, subject to the provisions of this Section 10.6. The arbitration shall be conducted as follows:

10.6.1.1The arbitration shall be conducted by three arbitrators, each of whom by training, education, or experience has knowledge of the research, development, and commercialization of biological therapeutic products in the United States. The arbitration shall be conducted in English and held in New York, New York.

10.6.1.2In its demand for arbitration, the Party initiating the arbitration shall provide a statement setting forth the nature of the dispute, the names and addresses of all other parties, an estimate of the amount involved (if any), the remedy sought, otherwise specifying the issue to be resolved, and appointing one neutral arbitrator. In an answering statement to be filed by the responding Party within [***] after confirmation of the notice of filing of the demand is sent by the AAA, the responding Party shall appoint one neutral arbitrator. Within [***] from the date on which the responding Party appoints its neutral arbitrator, the first two arbitrators shall appoint a chairperson.

10.6.1.3If a Party fails to make the appointment of an arbitrator as provided in Section 10.6.1.2, the AAA shall make the appointment. If the appointed arbitrators fail to appoint a chairperson within the time specified in Section 10.6.1.2 and there is no agreed extension of time, the AAA shall appoint the chairperson.

10.6.1.4The arbitrators will render their award in writing and, unless all Parties agree otherwise, will include an explanation in reasonable detail of the reasons for their award. Judgment upon the award rendered by the arbitrators may be entered in any

court having jurisdiction thereof, including in the courts described in Section 10.5. The arbitrators will have the authority to grant injunctive relief and other specific performance; provided that the arbitrators will have no authority to award damages in contravention of this Agreement, and each Party irrevocably waives any claim to such damages in contravention of this Agreement. The arbitrators will, in rendering their decision, apply the substantive law of the State of New York, without giving effect to conflict of law provisions that may require the application of the laws of another jurisdiction. The decision and award rendered by the arbitrators will be final and non-appealable (except for an alleged act of corruption or fraud on the part of the arbitrator).

10.6.1.5The Parties shall use their reasonable efforts to conduct all dispute resolution procedures under this Agreement expeditiously, efficiently, and cost-effectively.

10.6.1.6All expenses and fees of the arbitrators and expenses for hearing facilities and other expenses of the arbitration will be borne equally by the Parties unless the Parties agree otherwise or unless the arbitrators in the award assess such expenses against one of the Parties or allocate such expenses other than equally between the Parties. Each of the Parties will bear its own counsel fees and the expenses of its witnesses except to the extent otherwise provided in this Agreement or by applicable law.

10.6.1.7Compliance with this Section 10.6 is a condition precedent to seeking relief in any court or tribunal in respect of a dispute, but nothing in this Section 10.6 will prevent a Party from seeking equitable or other interlocutory relief in the courts of appropriate jurisdiction, pending the arbitrators’ determination of the merits of the controversy, if applicable to protect the confidential information, property, or other rights of that Party or to otherwise prevent irreparable harm that may be caused by the other Party’s actual or threatened breach of this Agreement.

10.7 No Discrimination. Licensee and its Affiliates, and Licensee shall use reasonable efforts to require that any Sublicensees, in their respective activities under this Agreement, shall not discriminate against any employee or applicant for employment because of race, color, sex, sexual, or affectional preference, age, religion, national, or ethnic origin, handicap, or because he or she is a disabled veteran or a veteran (including a veteran of the Vietnam Era).

10.8 Compliance with Law. Licensee (and its Affiliates’ and any Sublicensees’) must comply with all prevailing laws, rules, and regulations that apply to its activities or obligations under this Agreement. Without limiting the foregoing, it is understood that this Agreement may be subject to United States laws and regulations controlling the export of technical data, computer software, laboratory prototypes, and other commodities, articles, and information, including the Arms Export Control Act as amended in the Export Administration Act of 1979 and that Licensee’s obligations are contingent upon compliance with applicable United States export laws and regulations. The transfer of certain technical data and commodities may require a license from the cognizant agency of the United States Government and/or written assurances by Licensee that Licensee shall not export data or commodities to certain foreign countries without prior approval of such agency. Licensor neither represents that a license is not required nor that, if required, it will issue.

10.9 Entire Agreement. This Agreement, together with all exhibits hereto, embody the entire understanding between the Parties relating to the subject matter hereof and supersede all prior understandings and agreements, whether written or oral, including that certain Mutual Non-Disclosure Agreement dated May 15, 2015 between Licensor and AAVLife SAS. All “Confidential Information” (as defined in such Mutual Non-Disclosure Agreement) disclosed by one Party to the other Party pursuant to such Mutual Non-Disclosure Agreement shall be deemed “Confidential Information” of such disclosing Party under this Agreement (unless and until it falls within one of the exclusions set forth in Section 1.9). This Agreement may not be varied except by a written document signed by duly authorized representatives of both Parties.

10.10 Marking. Licensee, its Affiliates, and any Sublicensees shall mark any Licensed Product (or their containers or labels) made, sold, or otherwise distributed by it or them with any notice of patent rights necessary or desirable under applicable law to enable the Licensed Patents to be enforced to their full extent in any country where Licensed Products are made, used, sold, offered for sale, or imported.

10.11 Severability and Reformation. If any provision of this Agreement is held to be invalid or unenforceable by the arbitrators or a court of competent jurisdiction, then such invalid or unenforceable provision will be automatically revised to be a valid or enforceable provision that comes as close as permitted by law to the Parties’ original intent; provided that, if the Parties cannot agree upon such valid or enforceable provision, the remaining provisions of this Agreement will remain in full force and effect, unless the invalid or unenforceable provisions are of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without the invalid or unenforceable provisions.

10.12 Further Assurances. Each Party hereto agrees to execute, acknowledge, and deliver such further instruments, and to do all other reasonable acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

10.13 Interpretation; Construction. The captions to the several Articles and Sections of this Agreement are included only for convenience of reference and shall not in any way affect the construction of, or be taken into consideration in interpreting, this Agreement. In this Agreement, unless the context requires otherwise, (a) the word “including” shall be deemed to be followed by the phrase “without limitation” or like expression; (b) references to the singular shall include the plural and vice versa; (c) references to masculine, feminine, and neuter pronouns and expressions shall be interchangeable; (d) the words “herein” or “hereunder” relate to this Agreement; (e) “or” is disjunctive but not necessarily exclusive; (f) the word “will” shall be construed to have the same meaning and effect as the word “shall”; (g) all references to “dollars” or “$” herein shall mean U.S. Dollars; (h) unless otherwise provided, all reference to Sections, Articles, and exhibits in this Agreement are to Sections, Articles, and exhibits of and in this Agreement; and (i) whenever this Agreement refers to a number of days, such number shall refer to calendar days unless business days are specified.

Each Party represents that it has been represented by legal counsel in connection with this Agreement and acknowledges that it has participated in the drafting hereof. In interpreting and applying the terms and provisions of this Agreement, the Parties agree that no presumption will apply against the Party which drafted such terms and provisions.

10.14 Cumulative Rights and Remedies. The rights and remedies provided in this Agreement and all other rights and remedies available to either Party at law or in equity are, to the extent permitted by law, cumulative and not exclusive of any other right or remedy now or hereafter available at law or in equity. Neither asserting a right nor employing a remedy shall preclude the concurrent assertion of any other right or employment of any other remedy, nor shall the failure to assert any right or remedy constitute a waiver of that right or remedy.

10.15 Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument.

IN WITNESS WHEREOF, the Parties, intending to be legally bound, have caused this License Agreement to be executed by their duly authorized representatives.
