ARTICLE 2

LICENSE GRANT

2.1 Grant. Subject to the terms and conditions of this AGREEMENT, LICENSOR hereby grants to COMPANY (i) an exclusive license to develop, make, have made, use, import, offer for sale, sell, and have sold the LICENSED PRODUCT(S) and LICENSED SERVICES worldwide under the PATENT RIGHTS in the LICENSED FIELD. This license grant shall apply to the COMPANY and any AFFILIATED COMPANY, except that any AFFILIATED COMPANY shall not have the right to sublicense others as set forth in Paragraph 2.2 below. If any AFFILIATED COMPANY exercises rights under this AGREEMENT, such AFFILIATED COMPANY shall be bound by all terms and conditions of this AGREEMENT, including, but not limited to, indemnity and insurance provisions and royalty and other payment provisions, which shall apply to the exercise of the rights, to the same extent as would apply had this AGREEMENT been directly between LICENSOR and the AFFILIATED COMPANY. In addition, COMPANY shall remain fully liable to LICENSOR for all acts, omissions and obligations of AFFILIATED COMPANY such that acts, omissions and obligations of the AFFILIATED COMPANY shall be considered acts, omissions and obligations of the

COMPANY. This exclusive license grant is subject to (i) rights retained by the United States Government, if any, in accordance with the ▇▇▇▇-▇▇▇▇ Act of 1980 (established by P.L. 96-517 and amended by P.L. 98-620, codified at 35 USC § 200 et. seq. and implemented according to 37 CFR Part 401), and (ii) the retained rights of LICENSOR to make, have made and use the inventions claimed in the PATENT RIGHTS for LICENSOR’S internal, non-commercial research purposes. For the avoidance of doubt, LICENSOR shall continue to have the right to distribute its biological materials embodying PATENT RIGHTS for non-profit, academic research use under the material transfer agreements (MTAs) found in Exhibits E and F.

If LICENSOR transfers to a third party any Materials (as defined in the MTAs) covered in whole or part by the PATENT RIGHTS licensed to COMPANY, and is notified by any recipient of any inventions made with the use of such transferred Materials, including without limitation, any patent applications disclosing or claiming any such inventions, LICENSOR shall promptly notify COMPANY, providing any and all information that LICENSOR has regarding such inventions and/or patent applications. At the request of COMPANY, LICENSOR shall negotiate in good faith the terms of a non-exclusive, royalty-bearing worldwide license, with the right to sublicense to COMPANY, with regard to such inventions and/or patent applications to make, have made, use, offer for sale and sell products. LICENSOR shall consult with COMPANY regarding acceptable financial and other terms for any such license and not enter into any agreement with such third party except on terms acceptable to COMPANY. COMPANY shall be responsible for the payment to LICENSOR [***] to the third party for such a license; provided, in no event shall the amount payable to LICENSOR for such a license be more than LICENSOR owes to the third party for any such license. In the event that LICENSOR enters into any such license, the parties shall promptly enter into a written amendment to this AGREEMENT consistent with this paragraph.

2.2 Sublicense. COMPANY may grant SUBLICENSES under the PATENT RIGHTS to third parties pursuant to this AGREEMENT, subject to the terms and conditions of this Paragraph 2.2. COMPANY shall provide LICENSOR with an unredacted copy of each SUBLICENSE between COMPANY and a third party for the grant of rights under the PATENT RIGHTS within thirty (30) days of its execution. Each SUBLICENSE shall: (a) be consistent with the terms, conditions and limitations of this AGREEMENT, (b) name LICENSOR as an intended third party beneficiary of the obligations of SUBLICENSEE without imposition of obligation or liability on the part of LICENSOR or the INVENTORS to the SUBLICENSEE, and (c) [***]. Each SUBLICENSE furnished to LICENSOR by COMPANY shall be the Confidential Information of COMPANY. COMPANY shall (i) be and remain responsible for the performance by such SUBLICENSEE with the terms of this AGREEMENT, and any action by a SUBLICENSEE that would, if conducted by COMPANY be a breach of this AGREEMENT, shall be deemed a breach of this AGREEMENT by COMPANY, and (ii) ascertain, calculate, audit and collect all royalties that become payable by such SUBLICENSEE hereunder and take appropriate

enforcement action against such SUBLICENSEE for any failure to pay or to properly calculate payments. LICENSOR shall not exercise any of its rights as a third party beneficiary granted to it pursuant to clause (b) above unless: (w) LICENSOR has notified COMPANY in writing of the obligation of SUBLICENSEE sought to be enforced (the “Obligation”); (x) the Obligation has as its origin a requirement of this AGREEMENT; (y) COMPANY has failed to commence and continue to pursue reasonable steps within thirty (30) days of notice from LICENSOR pursuant to clause (w) above to enforce the Obligation or SUBLICENSEE has not fulfilled the Obligation within ninety (90) days of notice to COMPANY pursuant to clause (w) above, and (z) at the time LICENSOR asserts its rights as a third party beneficiary against SUBLICENSEE, LICENSOR shall have a reasonable basis for believing that SUBLICENSEE is in breach of the Obligation sought to be enforced.

2.3 Government Rights. The United States Government has acquired a nonexclusive, nontransferable, irrevocable, paid-up license to practice or have practiced for or on behalf of the United States the inventions described in PATENT RIGHTS throughout the world. The rights granted herein are additionally subject to, and expressly conditioned upon compliance with (i) the provisions of the ▇▇▇▇-▇▇▇▇ ▇▇▇, ▇▇ USC § 200 et seq, and (ii) other rights acquired, or requirements imposed, by the United States government under the grant/contract award terms and the laws and regulations applicable to the grant/contract award under which the inventions were made.

2.4 Duties of the Parties. LICENSOR is an institute of research and education and not a commercial organization. Therefore, LICENSOR has no ability to evaluate the commercial potential of any PATENT RIGHTS, LICENSED PRODUCT or LICENSED SERVICES or other license or rights granted in this AGREEMENT. It is therefore incumbent upon COMPANY to evaluate the rights, products and services in question, to examine the materials and information provided by LICENSOR and to determine for itself the validity of any PATENT RIGHTS, its freedom to operate, and the value of any LICENSED PRODUCTS or LICENSED SERVICES or other rights granted.

ARTICLE 3

FEES, ROYALTIES, & PAYMENTS

3.1 License Fee. COMPANY shall pay to LICENSOR within [***] of the EFFECTIVE DATE a license fee as set forth in Exhibit B.

Such royalties shall [***] based on [***] related to LICENSED PRODUCTS and LICENSED SERVICES.

Notwithstanding anything to the contrary in this AGREEMENT, in order to insure LICENSOR the full royalty and other payments contemplated hereunder, COMPANY agrees that in the event any LICENSED PRODUCT(S) or LICENSED SERVICES shall be sold to a corporation, firm or association (the “PURCHASER”) with which COMPANY shall have any agreement, understanding or arrangement with respect to consideration (such as, among other things, an option to purchase stock or actual stock ownership, or an arrangement involving division of profits or special rebates or allowances) received by COMPANY with respect to sale of such LICENSED PRODUCT(S) or LICENSED SERVICES, the royalties to be paid hereunder to LICENSOR for such LICENSED PRODUCT(S) or LICENSED SERVICES shall be based upon the greater of: 1) the [***] of the LICENSED PRODUCT(S) or LICENSED SERVICES as of the date that COMPANY receives such consideration from such PURCHASER, or 2) the [***] of LICENSED PRODUCT(S) or LICENSED SERVICES paid by the PURCHASER.

COMPANY shall not directly or indirectly accept [***].

3.5 Milestone Payments. COMPANY shall pay to LICENSOR the milestone payments as set forth in Exhibit C for the term of this AGREEMENT. For the avoidance of doubt, clinical trials of LICENSED PRODUCT conducted by COMPANY or on its behalf by other entities with respect to which COMPANY owns or has the right to use the data resulting

All non-US taxes (excluding any taxes based on LICENSOR’S income) related to milestone payments shall be paid by COMPANY and shall not be deducted from payments due to LICENSOR.

3.6 Patent Prosecution Reimbursement. COMPANY will reimburse LICENSOR, within thirty (30) days of the EFFECTIVE DATE the amount of [***] for costs associated with the preparation, filing, maintenance, and prosecution of PATENT RIGHTS incurred by LICENSOR on or before the EFFECTIVE DATE.

3.8 Late Payments. In the event that any payment due hereunder is not made when payable, the payment shall accrue interest beginning on the tenth day following the due date thereof, calculated at the rate of [***] per month from the date said payment is due, provided however, that in no event shall said annual interest rate exceed the maximum legal interest rate for corporations. Each such payment when made shall be accompanied by all interest so accrued. Said interest and the payment and acceptance thereof shall not negate or

waive the right of LICENSOR to seek any other remedy, legal or equitable, to which it may be entitled because of the delinquency of any payment including, but not limited to termination of this AGREEMENT as set forth in Article 9.

3.9 Withholding Taxes. Notwithstanding that LICENSOR is a tax-exempt entity under the United States Internal Revenue Code, as amended, in the event that payments due to LICENSOR in respect of NET SALES in jurisdictions other than the United States are subject to required withholding, such taxes shall be deducted by COMPANY (or its SUBLICENSEES) from such payment prior to remittance, and shall be paid over to the relevant taxing authorities when due. COMPANY shall promptly furnish LICENSOR evidence of any such taxes withheld and of payment thereof, and shall render reasonable assistance to LICENSOR in connection with its invocation of available procedures to seek refund of such payments.

ARTICLE 4

PATENT PROSECUTION, MAINTENANCE, & INFRINGEMENT

4.1 Prosecution & Maintenance. LICENSOR [***] shall be the PARTY responsible for the filing, prosecution and maintenance of patents and patent applications specified under PATENT RIGHTS and, subject to the terms and conditions of this AGREEMENT, COMPANY shall be licensed thereunder. Title to all such patents and patent applications shall reside in LICENSOR. LICENSOR shall have full and complete control over all patent matters in connection therewith under the PATENT RIGHTS, provided however, that LICENSOR shall (a) cause its patent counsel, reasonably acceptable to COMPANY, to timely copy COMPANY on all official actions and written correspondence with any patent office, and (b) allow COMPANY and/or counsel appointed by COMPANY an opportunity and reasonably sufficient time to comment and advise LICENSOR with respect thereto. The exercise of such right by COMPANY shall not interfere with the timely filing or submission of any document with, or response to, any official patent office. LICENSOR shall consider in good faith and reasonably incorporate all comments and advice from COMPANY, to the extent that they would tend to cover in more specificity, support or expand the scope of rights sought. By concurrent written notification to LICENSOR and its patent counsel at least [***] in advance of any filing or response deadline, or fee due date, COMPANY may elect not to have a patent application filed in any particular country or not to pay expenses associated with prosecuting or maintaining any patent application or patent within PATENT RIGHTS, provided that COMPANY pays for [***] incurred up to LICENSOR’S receipt of such notification. Failure to provide such notification can be considered by LICENSOR to be COMPANY’s authorization to proceed [***]. Upon such notification, at LICENSOR’S own expense, LICENSOR may file, prosecute, and/or maintain such patent applications or patent within the PATENT RIGHTS with respect to which COMPANY has made the foregoing decision(s) (collectively, the “COMPANY-DECLINED PATENTS”), and any rights or license granted hereunder held by COMPANY, AFFILIATED COMPANIES or SUBLICENSEE(S) relating to COMPANY-DECLINED PATENTS shall terminate.

4.2 Notification. Each PARTY will notify the other promptly in writing when any infringement by a third party is uncovered or suspected.

4.3 Infringement.

a. General. Except as is set forth in Paragraph 4.3b, COMPANY shall have the first right to conduct and control, [***], all patent litigation relating to the PATENT RIGHTS during the Term, including the first right to enforce any patent within PATENT RIGHTS against any infringement or alleged infringement thereof, and shall at all times keep LICENSOR informed as to the status of all such litigation. Before COMPANY may commence an action with respect to any infringement of the PATENT RIGHTS, it must obtain the consent of LICENSOR, such consent not to be unreasonably withheld. Thereafter, COMPANY may, in its sole discretion and at its own expense, may institute suit against any such infringer or alleged infringer and control and defend such suit in a manner consistent with the terms and provisions hereof and recover any damages, awards or settlements resulting therefrom, to be shared by COMPANY and LICENSOR in the manner set forth below. However, no settlement, consent judgment or other voluntary final disposition of the suit may be entered into without the prior written consent of LICENSOR. LICENSOR shall not unreasonably withhold consent of any settlement, consent judgment or other voluntary final disposition of suit that does not admit the invalidity of any patent within PATENT RIGHTS and which does not purport to admit any fault or wrongdoing on the part of LICENSOR. LICENSOR shall reasonably cooperate in any such litigation, [***] including by joining as a party if required by applicable law.

If COMPANY elects not to enforce any patent within the PATENT RIGHTS, then it shall so notify LICENSOR in writing within [***] of receiving notice that an infringement or suspected infringement exists. LICENSOR may, in its sole judgment and at its own expense, take steps to enforce any patent and commence, control, settle, and defend any such suit in a manner consistent with the terms and provisions hereof, and recover any damages, awards or settlements resulting therefrom, to be shared by COMPANY and LICENSOR in the manner set forth below. At LICENSOR’s request, COMPANY shall reasonably cooperate with any such litigation, at LICENSOR’s expense.

Ongoing Litigation. COMPANY shall have the obligation to join as a party, and control, pursue and defend, at its own expense, through counsel reasonably acceptable to LICENSOR, the following actions to which LICENSOR is a party, namely: Trustees of the University of Pennsylvania v. St. Jude Children’s Research Hospital Civil Action No. [***] (the “Contract Claim”) and Trustees of the University of Pennsylvania v. St. Jude Children’s Research Hospital Civil Action No. 13-1502 (the “Patent Claim”) in a manner consistent with the terms and provisions hereof. COMPANY shall at all times keep LICENSOR informed as to the status thereof, and shall allow LICENSOR and counsel appointed by LICENSOR an opportunity, and reasonably sufficient time, to comment and advise COMPANY with respect to actions to be taken in connection therewith. Commencing as of the EFFECTIVE DATE, COMPANY shall be responsible for [***] of LICENSOR’s

documented reasonable costs and expenses incurred in connection with the foregoing litigation and LICENSOR shall be responsible for [***] ([***]). COMPANY shall reimburse LICENSOR for its share of such costs within [***] of the receipt of an invoice from LICENSOR. Any recovery in such action (from damages, awards or settlements) shall be allocated as follows: first, LICENSOR shall receive past litigation costs of approximately [***] U.S. dollars ($[***]) to reimburse it for LICENSOR’s documented costs and expenses incurred in connection with the foregoing litigation prior to the EFFECTIVE DATE (exact costs to be included in an amendment to this AGREEMENT within 3 months of the EFFECTIVE DATE), second each party shall be reimbursed for its costs and expenses incurred by it in connection with such actions after the EFFECTIVE DATE, and then any remainder shall be shared [***] percent ([***]%) to COMPANY and [***] percent ([***]%) to LICENSOR. However, no settlement, consent judgment or other voluntary final disposition of the suit may be entered into without the prior written consent of LICENSOR. Except as is set forth below, LICENSOR shall not unreasonably withhold consent of any settlement, consent judgment or other voluntary final disposition of suit that does not admit the invalidity of any patent within PATENT RIGHTS and which does not purport to admit any fault or wrongdoing on the part of LICENSOR. LICENSOR shall reasonably cooperate in any such actions, at COMPANY’s expense, including by joining as a party if required by applicable law. Any settlement, consent judgment or other voluntary disposition of the Contract Claim shall include a provision acceptable to LICENSOR requiring that proper credit be given to LICENSOR and the INVENTORS in the work previously performed and to be performed thereafter by any of the defendants. For the avoidance of doubt, the sharing of recovery provisions set forth above shall govern the division between the LICENSOR and the COMPANY of any consideration payable by, on behalf of, or through the University of Pennsylvania and its affiliates (“Penn”) [***], and shall not be subject to the provisions of Exhibit B, Paragraph 4.

c. Prospective Patent Litigation. With respect to any litigation controlled by COMPANY pursuant to Paragraph 4.3a, COMPANY shall at all times keep LICENSOR informed as to the status thereof and shall (a) cause its litigation counsel, which counsel shall be reasonably acceptable to LICENSOR, to timely copy LICENSOR on all official actions and written correspondence, and (b) allow LICENSOR and counsel appointed by LICENSOR an opportunity and reasonably sufficient time to comment and advise COMPANY with respect thereto, [***]; provided that [***] must be reasonable and reflect that COMPANY is controlling the conduct of such litigation. COMPANY, in responding to the comments and advice of LICENSOR, shall give careful consideration to the views of LICENSOR and to potential effects on LICENSOR’S interests under this AGREEMENT and to potential effects on the public interest in any such action. However, no settlement, consent judgment or other voluntary final disposition of the suit may be entered into without the prior written consent of LICENSOR. LICENSOR shall not unreasonably withhold consent of any settlement, consent judgment or other voluntary final disposition of suit that does not admit the invalidity of any patent within PATENT RIGHTS and which does not purport to admit any fault or wrongdoing on the part of

LICENSOR. LICENSOR shall cooperate fully with COMPANY in connection with any litigation related to PATENT RIGHTS, [***]. Any recovery obtained as a result of such litigation shall (i) first, go to reimburse the PARTY controlling the litigation for its out of pocket costs in connection with such litigation; (ii) second, from any damages awarded other than for willful infringement, LICENSOR shall receive the equivalent of [***] based on the [***] or [***] (i.e., an amount equal to [***]), and (iii) any damages awarded for willful infringement shall go [***] percent ([***]%) to the PARTY controlling the litigation and [***] percent ([***]%) shall go to the other PARTY.

(c) COMPANY shall further provide in conjunction with the reports due pursuant to Paragraphs 5.1(a) and 5.1(b), the following information:

[***]

5.2 Records. COMPANY shall make and retain, for a period of [***] following the period of each report required by Paragraph 5.1(a), true, complete and accurate records, files and books of account containing all the data reasonably required for the full computation and verification of sales and other information required in Paragraph 5.1(a). Such books and records shall be in accordance with generally accepted accounting principles consistently applied. COMPANY shall permit the inspection of such records, files and books of account by LICENSOR’S agent (the “Auditor”), which Auditor shall be a nationally recognized auditor acceptable to COMPANY, such acceptance not to be unreasonably withheld, and subject to obligations of confidentiality and nonuse owed to LICENSOR consistent with the confidentiality and non-use obligations set forth in this Agreement. Any such inspection shall occur during regular business hours upon [***] written notice to COMPANY. Such inspection shall not be made more than once each calendar year. All costs of such inspection shall be paid by LICENSOR, provided that if any such inspection shall reveal that an error or omission has been made resulting in an underpayment equal to [***], the costs of such inspection shall be borne by COMPANY.

COMPANY shall notify LICENSOR well in advance if COMPANY believes that it will fail to achieve the Development Milestones in the expected timeframe as detailed in Exhibit C despite its exercise of commercially reasonable and diligent efforts.

If COMPANY fails to achieve any of the Development Milestones described in Exhibit C within the timeframes specified due to causes that are beyond the reasonable control of COMPANY, (e.g., regulatory action or delay, low patient enrollment, in each case, provided that the COMPANY has conducted the relevant activities in a reasonable manner), notwithstanding COMPANY’s reasonable, good faith efforts to achieve those milestones, then COMPANY will not be deemed in default or breach of this AGREEMENT and the timeframe for achieving those milestones will be deemed automatically extended by the time of the delay reasonably attributable to the causes that were beyond COMPANY’s control as long as COMPANY diligently and continuously pursues the achievement of such milestones. A failure on the part of COMPANY [***] to pursue timely achievement of the Development Milestones shall be deemed to be a failure within the control of COMPANY.

In the event that the foregoing paragraph does not apply, if the COMPANY fails to reach any milestone in Exhibit D for which a payment is required, then COMPANY may extend that milestone completion date and all subsequent milestone completion dates for a period of [***] (each a “Delayed Milestone”). In order to be entitled to that extension, COMPANY shall, within [***] after the applicable deadline for the achievement of the applicable milestone (i) pay to LICENSOR [***] of the Milestone Payment that would otherwise have been due had COMPANY timely achieved the applicable Milestone and (ii) [***]. If COMPANY fails to reach any Delayed Milestone, then COMPANY may obtain a further [***] month extension. In order to be entitled to the second extension, COMPANY shall, within [***] after the deadline for the achievement of the unachieved Delayed Milestone (a) pay to LICENSOR [***] of the Milestone Payment that would otherwise have been due had COMPANY timely achieved the Delayed Milestone, and (b) [***]. Total delays granted under this provision shall not exceed [***]. Notwithstanding the above, with regard to milestone 1(g) on Exhibit C ([***]), in the event that COMPANY fails to timely achieve this milestone and seeks one or more extensions under this paragraph the payment due for any such extension shall be [***].

Subject to the terms of this Paragraph 5.3, failure by COMPANY or its SUBLICENSEES to achieve the Development Milestones within the extended timeframe or to diligently and continuously purse the achievement of the Milestones shall be a breach of Paragraph 5.3, and may result in the [***]. In the event COMPANY ceases all activities directed at the development and commercialization of LICENSED PRODUCT(S) and LICENSED SERVICES, the rights granted to COMPANY under this AGREEMENT shall terminate immediately without further action of either PARTY.
