	 	9.1.2	 A Dispute among the parties will be resolved as recited in this Article 9. Any Disputes relating to this
Agreement shall be promptly presented to the Chief Executive Officers of Licensor and the Company, or their respective designees (who must be members of a party’s senior management) for resolution. From the date of referral of a Dispute to the
Chief Executive Officers or their designees of the parties and until such time as any matter has been resolved by the parties or has been finally settled by arbitration hereunder, the running of the cure periods (if any) as to which a party must
cure a breach that is part of the subject matter of any Dispute shall be suspended. In the event that the Chief Executive Officers of Licensor and the Company, or their respective designees, cannot after good faith negotiations resolve the Dispute
within [***] days (or such other period of time as mutually agreed to by the parties in writing) of being requested by a party to resolve a Dispute, the parties agree that such Dispute shall be resolved by binding arbitration in accordance with this
Article 9. 

  

	 	9.1.3	 If a party intends to begin arbitration to resolve such Dispute, such party shall provide written notice (the
“Arbitration Notice”) to the other party informing such other party of such intention and the issues to be resolved. Any arbitration hereunder shall be conducted pursuant to the Commercial Arbitration Rules of the American Arbitration
Association (“AAA”; such rules, the “AAA Rules”), except as modified herein. The arbitration shall be conducted by a panel of three (3) independent, neutral arbitrators that are industry experts experienced in the issues
comprising the Dispute and have no past, present or reasonably 

  
 13 

	 	
anticipated future affiliation with either party (the “Panel”). Company and Licensor shall each be entitled to select one (1) such arbitrator, with the two such arbitrators so
selected selecting the third such arbitrator. In the event either party fails to select its arbitrator within such [***] day period, the arbitrator selected by the other party within such [***] day period shall be entitled to select such arbitrator.
The arbitration shall take place in Houston, Texas and be conducted in English. The Panel shall apply the laws of the Commonwealth of Massachusetts, without regard to its conflicts of laws provisions. The Panel shall issue appropriate protective
orders to protect each party’s Confidential Information. If a party can demonstrate to the Panel that the complexity of the issue or other reasons warrant the extension of one or more timetables in the AAA Rules, the Panel may extend such
timetables but in no event shall the proceeding extend more than [***] months from the date of filing of the arbitration notice with the AAA. The Panel’s decision shall be in writing. The Panel shall have the authority to award any remedy
allowed by law, including but not limited to compensatory damages, pre-judgment interest, but not punitive or other damages and each party shall be deemed to have waived any right to such excluded damages.
Each party shall bear its own costs, fees and expenses in the arbitration and shall share equally the Panel’s fees, unless the Panel determines that its fees are to be paid by the non-prevailing party.
Notwithstanding anything to the contrary, without prejudice to the above procedures, either party may seek injunctive relief or other provisional judicial relief if, in its reasonable judgment, such action is necessary to avoid irreparable damage or
otherwise enforce its rights hereunder. 

  

	9.2	 Performance to Continue 

Each party shall continue to perform its obligations, and shall be permitted to continue to exercise its rights, under this Agreement pending final resolution
of any Dispute arising out of or related to this Agreement; provided, however, that a party may suspend performance of its obligations during any period in which the other party fails or refuses to perform its obligations. 

 

	9.3	 Determination of Patents and Other Intellectual Property 

Notwithstanding the foregoing, any dispute relating to the determination of validity of claims, infringement or claim interpretation relating to
Licensor’s Patent Rights shall be submitted exclusively to the courts. 
  

	9.4	 Statute of Limitation and Time-Based Defenses Tolled 

All applicable statutes of limitation and time-based defenses (such as estoppel and laches) shall be tolled while any arbitration proceedings are pending and
during any arbitration proceedings. The parties shall cooperate in taking any actions necessary to achieve this result. 

  
 14 

 Article 10 Term and Termination 

 

	10.1	 Term 

This Agreement shall become effective on the Effective Date and shall expire on the date of the expiration of the last to expire Royalty Term in any country in

license granted hereunder by giving [***] days prior written notice to the Company. Upon the expiration of the [***] day period, if the Company shall have not cured such breach or default, this Agreement shall, at the option of Licensor, terminate
upon written notice of Licensor. If a good faith dispute regarding termination is addressed pursuant to Article 10, this license shall remain in full force and effect until such dispute is resolved. All applicable statutes of limitation and
time-based defenses (such as estoppel and laches) shall be tolled while any good faith negotiation or mediation procedures are pending or ongoing. The parties shall reasonably cooperate in taking any actions necessary to achieve this result. 

 

	10.4	 Expiration of Royalty Term on a Country by Country Basis 

Upon the expiration of the Royalty Term in each country in the Territory, the Company will have an irrevocable, perpetual, paid up, royalty-free exclusive

Know-how shall revert to and become the sole property of Licensor, and the licenses granted under Article 2.1 shall automatically terminate.

	 	10.6.2	 Notwithstanding Article 10.6.1, if this Agreement is terminated other than pursuant to Article 10.5, the
Company and its Affiliates may, after the effective date of such termination and continuing for a period not to exceed [***] months thereafter, sell all completed Licensed Products, and complete (or have completed) any Licensed Products in the

limited to patent prosecution documents relating to Patent Rights), reports and records provided under Articles 3.1, 4.2 and 7, and any other reasonably confidential or proprietary information concerning a party’s business or technology
disclosed to the other party under this Agreement collectively constitute the “Confidential Information.” Neither party will use the Confidential Information for any purpose unrelated to the exercise of their rights or fulfillment of their
obligations under this Agreement, and will hold it in confidence during the Term and for a period of [***] years after the termination or expiration date of this Agreement. Each party shall exercise with respect to such the Confidential Information
the same degree of care as the party exercises with respect to its own confidential or proprietary information of a similar nature, but in no event less than reasonable care, and shall not disclose it or permit its disclosure to any Third Party
(except to those of its employees, consultants, or agents who are bound by a substantially similar obligation of confidentiality of this Agreement). However, such undertaking of confidentiality shall not apply to any information or data which:

possession of same and having the right to disclose same; 

  

	 	13.1.2	 is, as of the date of this Agreement, in the public domain, or subsequently enters the public domain through no
fault of the receiving party; 

  

	 	13.1.3	 is independently developed by the receiving party as demonstrated by written evidence without reference to or
benefit of information disclosed to the receiving party by the disclosing party; 

  

	 	13.1.4	 is disclosed pursuant to the prior written approval of the disclosing party; or 

 

	 	13.1.5	 is required to be disclosed pursuant to Applicable Law or legal process (including, without limitation, to a
governmental authority) provided that recipient will (i) give prior written notice of such required disclosure to the other party, to the extent reasonably practicable, (ii) give reasonable assistance to the other party, as requested
thereby, seeking confidential or protective treatment thereof, and (iii) only disclose such Confidential Information to the extent required by such Applicable Law or legal process. 

 

	13.2	 Material Non-Public Information 

The Company understands that it is the intent of the Licensor to register its capital stock on a national securities exchange or the Over the Counter Bulletin
Board and accordingly, the Licensor understands that confidential information provided to it by the Company pursuant to the terms of this Agreement may constitute “material non-public information”
concerning the Company.

THE BRIGHAM AND WOMEN’S HOSPITAL,
INC. 
 EXCLUSIVE PATENT LICENSE AGREEMENT 

BWH Agreement No: [***] 

BWH Case No: [***], [***], and [***] 

This License Agreement (“Agreement”) is made as of the 15th day of September,
2020 (“Effective Date”), by and between Advantagene, Inc., a Delaware corporation, having a principal place of business at 440 Lexington Avenue, Auburndale, MA 02466 (“Company”) and The Brigham and Women’s
Hospital, Inc., a not-for-profit Massachusetts corporation, with a principal place of business at 75 Francis Street, Boston, Massachusetts 02115
(“Hospital”), each referred to herein individually as a “Party” and collectively as the “Parties”. 

RECITALS 
 Under research
programs funded by Hospital and the U.S. Government, Hospital through research conducted by Dr. Ennio Antonio Chiocca (“Principal Investigator”), has developed inventions pertaining to an oncolytic Herpes simplex virus which has been
modified for treatment of glioma, including but not limited glioblastoma multiforme, in patients. 
 Hospital, as a center for patient care,
research and education, is the owner of certain Patent Rights (defined below) covering the oncolytic Herpes simplex virus and desires to grant a license of those Patent Rights to Company in order to benefit the public by disseminating the results of
its research via the commercial development, manufacture, distribution and use of Licensed Products (defined below). Company has the capability to commercially develop, manufacture, distribute and use Licensed Products for public use and benefit and
desires to license such Patent Rights. 
 Hospital and Company previously entered into an Exclusive Option Agreement for the Patent Rights
on January 20, 2018 (BWH Agreement No.: A224945) in which Company has agreed to support a clinical trial at the Hospital for treatment of glioma patients with the oncolytic Herpes simplex virus described in the Patent Rights. 

For good and valuable consideration, the sufficiency of which is hereby acknowledged, the Parties hereby agree as follows: 

1.    CERTAIN DEFINITIONS 

As used in this Agreement, the following terms shall have the following meanings, unless the context requires otherwise. 

1.1    “Acquisition” shall have the meaning set forth in Section 4.4 (a)(iv). 

1.2    “Affiliate” with respect to either Party means any corporation or other legal entity other than that Party in
whatever country organized, controlling, controlled by or under common control with that Party. The term “control” means (i) in the case of Company, direct or indirect ownership of fifty percent (50%) or more of the voting
securities having the right to elect 

 
directors, and (ii) in the case of Hospital, the power, direct or indirect, to elect or appoint fifty percent (50%) or more of the directors or trustees, or to cause direction of management
and policies, whether through the ownership of voting securities, by contract or otherwise. 
 1.3    “BLA” or
“Biologics License Application” shall have the meaning set forth in Section 3.1(e). 

1.4    “Claim” means (i) an issued claim of any Patent Right that has not been permanently revoked, nor held
unenforceable or invalid by a decision of a court or other governmental agency of competent jurisdiction that is unappealable, or unappealed in the time allowed for appeal; and (ii) a pending claim included in the Patent Rights that was
filed in good faith and has not been pending for more than [***] years after the first office action and has not been abandoned or finally disallowed without the possibility of appeal or refiling such application. Notwithstanding the foregoing, if
any pending claim of the Patent Rights is issued or granted as a patent after [***] years after the first office action, it shall be deemed to be a Claim, subject to the provisions of this paragraph, for the entire period such patent application was
pending and for the remainder of the patent term. Further, within [***] days of the patent issue date, Company shall pay Hospital any royalties or milestones due on the pending claim during the period between [***] years after the first office
action until the patent is granted and shall continue to pay all applicable royalties and milestones for the remainder of the patent term. 

1.5    “Clinical Trial Agreement” means the agreement executed between Company and Hospital to conduct a human clinical
research study of rQNestin34.5v.2 in accordance with the study protocol entitled, “A Phase I study of the treatment of recurrent malignant glioma with rQNestin34.5v.2, a genetically engineered HSV-1
virus, and immunomodulation with cyclophosphamide” effective on June 19, 2018, as amended from time to time (MGH Agreement No. 2018A001280). 

1.6    “Commercially Reasonable Efforts” solely as applied to Company, means with respect to any objective relating to
the research, development, manufacture or commercialization of a Licensed Product, the efforts and resources normally used by a company in the biopharmaceutical industry for a product which is of similar market potential at a similar stage in its
development or commercialization, which level of effort is at least commensurate with the level of effort that any party would devote to its own internally discovered and funded products that are of most closely comparable market potential at a most
closely comparable stage in their development or product life, taking into account regulatory requirements of safety and efficacy, product profile, the competitiveness of the marketplace, the proprietary position of the Licensed Product, and the
cost of scaling up a manufacturing process (including, if applicable, facility costs), and the market potential of the applicable Licensed Product. 

1.7    “Derived Product” means any product that was developed using Hospital’s Technological Information for the
treatment of Glioma, but which is not covered by any Claim of the Patent Rights. 
 1.8    “Distributor” means any
Third Party entity to whom Company, a Company Affiliate or a Sublicensee has granted, express or implied, the right to distribute any Licensed Product pursuant to Section 2.1(b)(ii), with or without packaging rights, in circumstances where such

  
 2

greatest, by Company and its Affiliates and Sublicensees for or on account of Sales of Licensed Products to Hospital and Hospital’s Affiliates. 

  

	 	(b)	 Specifically excluded from the definition of “Net Sales” are amounts attributable to Sale of any

collections. 

  

	 	(d)	 Net Sales shall be deemed to have occurred and the applicable Licensed Product “Sold” on the earliest
of the date of billing, invoicing, delivery or payment or the due date for payment. 

  

	 	(e)	 If any Licensed Product is Sold for non-cash consideration (whether or
not at a discount), Net Sales shall be calculated based on the non-discounted amount charged to an independent Third Party for the Licensed Product during the same Reporting Period or, in the absence of such
transaction, on the fair market value of the Licensed Product, excluding, however, transfer of Licensed Products at no cost pursuant to research and development collaborations and for compassionate use programs and Hospital shall not construe such
transfers as “in kind” benefits or compensation. 

  

	 	(f)	 In the event Company or an Affiliate or Sublicensee uses an active ingredient (for clarity, an active
ingredient shall exclude any routine component, including common buffers and cell culture media) not licensed by Hospital to Company hereunder (“Other Component”) to form a product that is a combination of a

  
 4 

	 	
Product or Derived Product (“Licensed Component”) and Other Component(s) (a “Combination Product”), Net Sales for the purposes of calculating the royalty owed to Hospital on
Sales of such Licensed Component shall be calculated as described in the subsections below: 

  

	 	(i)	 If the Licensed Component and the Other Component contained in the Combination Product(s) are Sold separately
(whether as an ingredient for another product or as its own product combined with routine components that may include common buffers and cell culture media) during a given Reporting Period, then the royalty due under Section 4.5 shall be paid
on the Licensed Component Net Sales (“LCNS”) calculated as follows: 

 LCNS = Net Sales of such Combination
Product * (A/(A+B)); 
 where “A” (as used in this Section 1.20(f)(i)), is the average invoice price in such country during
the current and immediately preceding Reporting Period of any Product or Derived Product that contains the Licensed Component; and 

“B” (as used in this Section 1.20(f)(i)), is the average invoice price in such country during such Reporting Period of the
Other Components. 
  

	 	(ii)	 If the Combination Product contains Licensed Components or Other Components not sold separately, then the LCNS
for purposes of determining royalty payments shall be calculated as above, provided, however, that the Parties shall negotiate in good faith over a period of [***] days the value for A and B in the above equation. Notwithstanding the foregoing, if
Company owns all material components to the Combination Product, it shall determine the retail price of the Combination Product in good faith and may not use the Licensed Product component as a “loss leader.” If Hospital reasonable
believes that the retail price of the Combination Product is unfair because the Company is, in the opinion of Hospital, using the Product as a loss leader, then it may challenge the Company’s allocation of relative value (and thus royalties due
to Hospital) pursuant to Section 10.5. 

  

	 	(iii)	 Notwithstanding the foregoing calculation of LCNS, Company agrees that it shall not pay a royalty amount to
Hospital on any LCNS of such Combination Product that is less than [***]percent ([***]%) of the Net Sales of such unit of Combination Product that includes a Product or that is less than [***]percent ([***]%) of the Net Sales of such unit of
Combination Product that includes a Derived Product. 

 1.20    “Marketing Authorization Approval” or
“MAA” means marketing authorization approval (including approval of a BLA) that has been granted for any Product. 

1.21    “Major Market Country” means Australia, Canada, China, France, Germany, Italy, Japan, Spain, the United Kingdom,

portion of any minimum royalty payment, distribution or joint marketing fee and research and development funding in excess of the cost of performing such research and development, and (ii) consideration received for an equity interest
in, extension of credit to, or other investment in Company or Company’s Affiliates to the extent such consideration exceeds the fair market value of the equity or other interest received as determined by an independent appraiser mutually
agreeable to the Parties, provided, however, that the fees or consideration described in (i) and (ii) are directly attributable to a grant of a sublicense, license, privilege or immunity. For clarity,
Non-Royalty Income shall not include consideration received by the Company’s stockholders pursuant to the disposition or transfer of all, or substantially all, of the Company’s assets, whether by
sale, merger, acquisition, operation of law or otherwise. 
 1.23    “Patent Rights” means, inclusively, the U.S.

 1.33    “Sublicensee” means any
sublicensee of rights granted in accordance with Section 2.1(a)(iii). For purpose of this Agreement, a Distributor of a Licensed Product shall not be included in the definition of Sublicensee unless such Distributor (a) is granted

modified to reflect any modified Plan, subject in each case to the reasonable approval of the Hospital, such approval not unreasonably withheld, conditioned, or delayed. However, if following any approval of an amended Plan by Hospital (and
subsequently the amended Diligence Requirements), Company has failed to fulfill any of its obligations under Section 3.1 or comply with the provisions of Section 3.2 relating to such amended Diligence Requirements, then
Hospital may treat such failure as a default and may terminate this Agreement and/or any license granted hereunder in accordance with Section 10.4, subject to applicable cure periods. Failure for Company to achieve the specific Diligence
Requirement under Section 3.1(f) shall not result in termination of this Agreement, but such failure shall restrict Company’s License Territory to the specific Major Market Country for which it has filed for a Biological License

therapy or a checkpoint inhibitor as a combination therapy shall be a Secondary Product. Company shall remit to Hospital payments upon occurrence of the following milestones for any Secondary Product, as described below: 

Clinical Milestones: 
  

	 	(i)	 A one-time payment of [***] U.S. Dollars ($[***]) upon the dosing of
the first patient with Secondary Product in a Phase 2 Clinical Trial of Glioma patients; and 

  

	 	(ii)	 A one-time payment of [***] U.S. Dollars ($[***]) upon the dosing of
the first patient with Secondary Product in a Pivotal Clinical Trial of Glioma patients; 

  

	 	(iii)	 A one-time payment of [***]U.S. Dollars ($[***]) upon approval of a BLA
for a Secondary Product by the FDA, or its equivalent application in any Major Market Country; and 

  

	 	(iv)	 Notwithstanding the foregoing, milestones 4.4(d)(i), 4.4(d)(ii), and 4.4(d)(iii) shall not become due and
payable to Hospital unless and until (i) such clinical milestone has been achieved and (ii) an Acquisition has taken place in which the stockholders of the Company prior to such Acquisition are not the majority Stockholders after
the closing of such Acquisition. If there is no Acquisition, the milestone set forth in 4.4(d)(i), 4.4(d)(ii), and 4.4(d)(iii) shall accrue when achieved and become payable by Company upon the occurrence of 4.4(d)(v) below (First Commercial Sale of
any Secondary Product in the United States). 

 Commercial Milestones: 

 

	 	(v)	 Subject to 4.4(d)(viii) below, a one-time payment of [***]U.S. Dollars
($[***]) upon the First Commercial Sale of any Secondary Product in the United States; 

  

	 	(vi)	 A one-time payment of [***]U.S. Dollars ($[***]) upon the First
Commercial Sale of any Secondary Product in Europe; 

  
 14 

	 	(vii)	 A one-time payment of [***]U.S. Dollars ($[***]) upon the First
Commercial Sale of any Secondary Product in Japan; and 

  

	 	(viii)	 If some or all of the clinical milestones for development of a Secondary Product in 4.4(d)(i), 4.4(d)(ii), and
4.4(d)(iii) have been accrued but not yet been remitted to Hospital pursuant to 4.4(d)(iv), such clinical milestones for Secondary Product shall be remitted upon achievement of First Commercial Sale of any Secondary Product in the United States in
4.4(d)(v) in addition to any payment due under such provision. 

 To avoid over-payment of any specific milestone listed in
Section 4.4, if a Sublicensee pays Company for achieving any of these same milestones listed in Section 4.4 and Company pays Hospital the entire amount of such milestone, then Company shall not be obligated to pay Hospital additional Non-Royalty Income on the amount already paid for such milestone, but shall be obligated to pay Hospital the Non-Royalty Income for any amount received in excess of the
amounts listed hereunder as well as Non-Royalty Income not associated with any of the milestones listed in Section 4.4. 

4.5    Royalties and Non-Royalty Income. 

 

	 	(a)	 Beginning with the First Commercial Sale by Company, its Affiliates, or Sublicensees in the applicable country
in the License Field in the License Territory, Company shall pay Hospital a royalty as provided below: 

 [***]% For the
portion of Net Sales of Product(s) in a given calendar year that is less than $[***] U.S. dollars; 
 [***]% For the portion of Net
Sales of Product(s) in a given calendar year that is greater than or equal to $[***] U.S. dollars but less than $[***] U.S. dollars; 

[***]% For the portion of Net Sales of Product(s) in a given calendar year that is greater than or equal to $[***] U.S. dollars; and

 [***]% For annual Net Sales of Derived Products. 
  

	 	(i)	 Subject to (ii) below, with respect to each Product or Derived Product (as applicable) and on a country-by-country basis, Company’s obligation to pay royalties would commence on the date of First Commercial Sale of such Product or Derived Product in each country and
would expire on the later of: (a) date on which there ceases to be a Claim of the Patent Rights in such country; (b) the expiration of all applicable periods of orphan designated drug, Hatch-Waxman or any other
statutory or regulatory exclusivity covering such Product and/or Derived Product(s) in such country (“Market Exclusivity”); or (c) [***] years after the First Commercial Sale of such Product and/or Derived Product. 

  
 15 

	 	(ii)	 In the event that a Product or is no longer covered by a Claim in a given country, Company shall be entitled to
reduce the royalty rate due to Hospital, as provided under Section 4.5(a), on Net Sales of such Product in such country, by [***]percent ([***]%) until the expiration of all applicable Market Exclusivity covering such Product in such country,
and at such time the Product shall become a Derived Product. 

  

	 	(iii)	 If, in order to develop, manufacture or sell Product(s), Company is required to pay a royalty to a Third Party
on a Product to avoid infringement of a Third Party’s patents, then Company shall be entitled to reduce the royalty payment due to Hospital only on such Product by [***]percent ([***]%) of the royalty payable to the Third Party(ies);
provided however, that under no circumstance shall the royalties due to Hospital on any Product be reduced by more than half of the amount that would otherwise have been payable to Hospital on the applicable royalty-bearing Net Sales. Any
royalties due to Hospital on Derived Product(s) shall not be similarly reduced. 

  

	 	(b)	 Notwithstanding the royalty deductions permitted under Section 1.20(f), 4.5(a)(ii), and 4.5(a)(iii) above,
under no event shall the royalty rate due to Hospital be lower than [***]percent ([***]%) for the Sale of any Product and [***]percent ([***]%) for the Sale of any Derived Product. 

 

	 	(c)	 Company shall pay Hospital a percentage of any and all Non-Royalty
Income attributable to the Sublicense of Licensed Product(s), as follows: 

 [***]% If such Sublicense occurs prior to the
dosing of first patient in a Phase 2 Clinical Trial of Licensed Product; 
 [***]% If such Sublicense occurs after dosing of first
patient in a Phase 2 Clinical Trial of Licensed Product but before approval of the BLA by the FDA, or approval of an equivalent application in another Major Market Country; and 

[***]% If such Sublicense occurs after approval of the BLA by the FDA, or approval of an equivalent application in another Major Market
Country. 
  

	 	(d)	 All payments due to Hospital under this Section 4.5 shall be due and payable by Company within [***] days
after the end of each Reporting Period and shall be accompanied by a report as set forth in Sections 5.3 and 5.4. 

4.6    Form of Payment. All payments due under this Agreement shall be drawn on a United States bank and shall be payable in United
States dollars. Each payment shall reference this Agreement and its Agreement Number and identify the obligation under this Agreement that the payment satisfies. Conversion of foreign currency to U.S. dollars shall be made at the conversion rate
existing in the United States, as reported in The Wall Street Journal, on the [***] day of the applicable Reporting Period. Such payments shall be without deduction of exchange, collection or other charges, and, specifically, without deduction of
withholding or similar taxes or other government-imposed fees or taxes, except as permitted in the definition of Net Sales.

5.5    Audit Rights. Company shall maintain, and shall cause each of its Affiliates and Sublicensees to maintain, complete and
accurate records relating to the rights and obligations under this Agreement and any amounts payable to Hospital in relation to this Agreement, which records shall contain sufficient information to permit Hospital and its representatives to confirm

year with reasonable notice to Company) pursuant to the provisions of this Section show an underreporting or underpayment of [***]percent ([***]%) or more in any payment due to Hospital hereunder, Company shall bear the full cost of such audit and
shall remit any amounts due to Hospital (including interest due in accordance with Section 4.7) within [***] days of receiving notice thereof from Hospital. This Section 5.5 shall survive for a period of [***] years following the
termination of this Agreement. 

  
 18 

 5.6    Confidential Reports and Records. All information shared between the
Parties pursuant to this Article 5 shall be “Confidential Information” under the Agreement between the Parties hereto and as set forth in Appendix E. The Hospital understands that it is the intention of the Company to become
publicly traded and that any information disclosed to Hospital under this Agreement, including the reports delivered hereunder, may be deemed “material non-public information” under the state and
federal securities laws. 
 6.    PATENT PROSECUTION AND MAINTENANCE 

6.1    Prosecution. Hospital shall be responsible for the preparation, filing, prosecution and maintenance of all patent
applications and patents included in Patent Rights, including, but not limited to, the filing of patent applications, extensions, continuations, continuations-in-part,
divisionals, re-examinations, or re-issue applications. Company shall be given the opportunity to review and provide input thereto. Company shall reimburse Hospital for
the Patent Costs incurred by Hospital relating thereto in accordance with Section 4.2. 
 6.2    Cooperation.
With respect to any Patent Right licensed hereunder, Hospital shall instruct patent counsel prosecuting such Patent Right to (i) copy Company on patent prosecution documents that are received from or filed with the United States Patent and
Trademark Office (“USPTO”) and foreign equivalent, as applicable; (ii) provide Company with copies of draft submissions to the USPTO and foreign equivalent, as applicable, prior to filing; and (iii) give
consideration to the comments and requests of Company or its patent counsel prior to submission. Both Parties agree to provide reasonable cooperation to each other to facilitate the application and prosecution of the Patent Rights pursuant to this
Agreement. 
 6.3    The Company shall promptly notify Hospital of the issuance of any Marketing Authorization Approval in each country
and, where reasonably possible, useful, or valuable in the commercialization of Products, use Commercially Reasonable Efforts to assist Hospital with applying for any term extension, adjustment, restoration, or supplementary protection certificate
pertaining to the Patent Rights, or other form of market exclusivity conferred by applicable laws and regulations (collectively, “Patent Term Extensions”) in the relevant country of the License Territory. Hospital shall, to the extent
reasonably possible, useful, or valuable in the commercialization of Products, use reasonable efforts to, if and as requested by Company, obtain all available Patent Term Extensions, at Company’s expense. The Parties shall cooperate with each
other in obtaining Patent Term Extensions wherever and whenever applicable, reasonably possible to obtain, and reasonably useful or valuable in the commercialization of Products. 

6.4    Company’s Election Not to Proceed. Company may elect to surrender any patent or patent application included in the
Patent Rights in any country upon [***] days advance written notice to Hospital. Such notice shall relieve Company from the obligation to pay for future Patent Costs but shall not relieve Company from responsibility to pay Patent Costs incurred
prior to the expiration of the [***] day notice period. Such U.S. or foreign patent application or patent shall thereupon cease to be a Patent Right hereunder with respect only to those countries in which such patents or patent applications were
surrendered by the Company, Company shall have no further rights therein and Hospital shall be free to license its rights to that particular U.S. or foreign patent application or patent to any Third Party on any terms. 

  
 19 

 6.5    Confidentiality of Prosecution and Maintenance Information. The Parties
hereto agree to treat all information related to prosecution and maintenance of Patent Rights as Confidential Information in accordance with the provisions of Appendix E. 

7.    THIRD PARTY INFRINGEMENT AND LEGAL ACTIONS 

7.1    Hospital Right to Prosecute. Company and Hospital shall promptly provide written notice to the other Party of any alleged
infringement or any challenge or threatened challenge to the validity, enforceability, or priority of any Patent Rights, and provide each other with any available evidence of such infringement, challenge or threatened challenge of the Patent Rights
by a Third Party. Hospital will protect its Patent Rights from infringement and prosecute infringers when, in its sole judgment, such action may be reasonably necessary, proper and justified. If Company shall have supplied Hospital with written
evidence demonstrating to Hospital’s reasonable satisfaction prima facie infringement of a claim of a Patent Right in the License Field and the License Territory by a Third Party which poses a material threat to Company’s rights under this
Agreement, Company may by notice request Hospital to take steps to protect such Patent Right. Hospital shall notify Company within [***] days after receipt of such notice whether Hospital intends to prosecute the alleged infringement. If Hospital
notifies Company that it intends to so prosecute, Hospital shall, within [***] days of its notice to Company, either: (i) cause such infringement to terminate, or (ii) initiate legal proceedings against the infringer. 

7.2    Company Right to Prosecute. In the event Hospital notifies Company that Hospital does not intend to prosecute infringement
identified under Section 7.1 or otherwise fails to initiate legal proceedings against the infringer as set forth in Section 7.1 above, Company may, upon notice to Hospital, initiate legal proceedings against the infringer at
Company’s expense with respect to a claim of a Patent Right in the License Field and the License Territory. Before commencing such action, Company and, as applicable, any Affiliate, shall consult with Hospital, concerning, among other things,
Company’s standing to bring suit, the advisability of bringing suit, the selection of counsel and the jurisdiction for such action and shall use reasonable efforts to accommodate the views of Hospital regarding the proposed action, including
without limitation, with respect to potential effects on the public interest. Company shall be responsible for all costs, expenses and liabilities in connection with any such action and shall indemnify and hold Hospital harmless therefrom,
regardless of whether Hospital is a party-plaintiff, except for the expense of any independent counsel retained by Hospital in accordance with Section 7.5 below. 

7.3    Hospital Joined as Party-Plaintiff. If Company elects to commence an action as described in Section 7.2 above, Hospital
shall have, in its sole discretion, the option to join such action as a party-plaintiff. If Hospital is required by law to join such action as a party-plaintiff, Hospital may either, in its sole discretion, permit itself to be joined as a
party-plaintiff at the sole expense of Company, or assign to Company all of Hospital’s right, title and interest in and to the Patent Right which is the subject of such action (subject to all of Hospital’s obligations to the government
under law and any other rights that others may have in such Patent Right). If Hospital makes such an assignment, such action by Company shall thereafter be brought or continued without Hospital as a party; provided however, that Hospital
shall continue to have all rights of prosecution and maintenance with respect to Patent Rights and Company shall continue to meet all of its obligations under this Agreement as if the assigned Patent Rights were still licensed to Company hereunder.

  
 20 

 7.4    Notice of Actions; Settlement. A Party shall not enter into any
settlement, consent judgment or other voluntary final disposition of any action relating to the Patent Rights, including but not limited to appeals, without the prior written consent of the other Party (the “Cooperating Party”). The
Cooperating Party shall provide the Controlling Party notice of its approval or denial of such approval within [***] business days of any request for such approval by the Controlling Party, provided that (i) in the event Cooperating Party wishes to
deny such approval, such notice shall include a written description of Cooperating Party’s reasonable objections to the proposed settlement, consent judgment, or other voluntary disposition. 

7.5    Cooperation. Each Party shall promptly inform the other if it becomes aware of any action or suit relating to the Patent
Rights. Each Party agrees to cooperate reasonably in any action under Section 7 which is controlled by the other Party, provided the Controlling Party reimburses the Cooperating Party for any costs and expenses incurred by the Cooperating Party in
connection with providing such assistance, except for the expense of any independent counsel retained by the Cooperating Party in accordance with this Section 7.5. The Controlling Party shall keep the Cooperating Party informed of the progress of
such proceedings and shall make its counsel available to the Cooperating Party. The cooperating party shall also be entitled to independent counsel in such proceedings but at its own expense, said expense to be offset against any damages received by
the Party bringing suit in accordance with Section 7.6. 
 7.6    Recovery. Any award paid by Third Parties as the result of such
proceedings (whether by way of settlement or otherwise) shall first be applied to reimbursement of any legal fees and expenses incurred by either Party and then the remainder shall be divided between the Parties as follows: 

 

	 	(a)	 (i)    Company shall receive an amount equal to its lost profits on the infringing sales,
or whichever measure of damages the court shall have applied; and 

  

	 	(ii)	 Hospital shall receive an amount equal to the royalties and other amounts that Company would have paid to
Hospital if Company had Sold the infringing Products rather than the infringer; and 

  

	 	(b)	 the balance, if any, remaining after Company and Hospital have been compensated under
Section 7.6(a) shall be shared equally by the Parties. 

 7.7    All communications and documents relating
to this Article 7 shall be deemed “Confidential Information” pursuant to the agreement entered into between the Parties hereto and attached as Appendix E. 

8.    INDEMNIFICATION AND INSURANCE 

8.1    Indemnification. 
  

	 	(a)	 Company shall indemnify, defend and hold harmless Hospital and its Affiliates and their respective trustees,
directors, officers, medical and professional staff, 

  
 21 

	 	
employees, and agents and their respective successors, heirs and assigns (the “Indemnitees”), against any liability, damage, loss or expense (including reasonable attorney’s fees
and expenses of litigation) (a “Loss”) incurred by or imposed upon the Indemnitees or any one of them in connection with any third party claims, suits, actions, demands or judgments arising from: (i) any theory of product
liability (including, but not limited to, actions in the form of contract, tort, warranty, or strict liability) concerning any product, process or service made, used, or sold or performed pursuant to any right or license granted under this
Agreement, or (ii) any claim by a third party that any Company product, process, or service made, used, or sold or performed pursuant to any right or license granted under this Agreement infringes any patent, copyright or trade secret,
or (iii) Company breach of its obligations under Section 2.2 or 8.2 of this Agreement; except to the extent that Company can demonstrate that a Loss as described in clause (i), (ii) or (iii) hereof directly
results from the gross negligence or intentional misconduct of Hospital and/or the Indemnitees. 

  

	 	(b)	 Company agrees, at its own expense, to provide attorneys reasonably acceptable to the Hospital to defend
against any actions brought or filed against any party indemnified hereunder with respect to the subject of indemnity contained herein, whether or not such actions are rightfully brought; provided however, that any Indemnitee shall have the
right to retain its own counsel, at the expense of Company, if representation of such Indemnitee by counsel retained by Company would be inappropriate because of conflict of interests of such Indemnitee and any other party represented by such
counsel. Company agrees to keep Hospital informed of the progress in the defense and disposition of such claim and to consult with Hospital prior to any proposed settlement. 

 

	 	(c)	 This section 8.1 shall survive expiration or termination of this Agreement. 

8.2    Insurance. 
  

	 	(a)	 Beginning at such time as any such product, process or service is being commercially distributed, sold, leased
or otherwise transferred, or performed or used (other than for the purpose of obtaining regulatory approvals), by Company, an Affiliate or Sublicensee, Company shall, at its sole cost and expense, procure and maintain commercial general liability
insurance in amounts not less than $[***] per incident and $[***] annual aggregate and naming the Indemnitees as additional insureds. Such commercial general liability insurance shall provide (i) product liability coverage and
(ii) broad form contractual liability coverage for Company’s indemnification under Section 8.1 of this Agreement. If Company elects to self-insure all or part of the limits described above (including deductibles or
retentions which are in excess of $[***] annual aggregate) such self-insurance program must be acceptable to the Hospital. The minimum amounts of insurance coverage required under this Section 8.2 shall not be construed to create a limit
of Company’s liability with respect to its indemnification under Section 8.1 of this Agreement. 

  
 22 

	 	(b)	 Company shall provide Hospital with written evidence of such insurance and the additional-insured status of the
Indemnitees upon request of Hospital. If possible, Company shall provide Hospital with written notice at least [***] days prior to the cancellation, non-renewal or material change in such insurance. Failure of
the Company to maintain the foregoing insurance shall be a material breach of this Agreement and the Hospital shall have the right to terminate this Agreement upon written notice pursuant to Article 10.3. 

 

	 	(c)	 Company shall maintain such commercial general liability insurance beyond the expiration or termination of this
Agreement during (i) the period that any such product, process, or service is being commercially distributed, sold, leased or otherwise transferred, or performed or used (other than for the purpose of obtaining regulatory approvals), by Company
or by a licensee, Affiliate or agent of Company and (ii) a reasonable period after the period referred to in (c) (i) above which in no event shall be less than [***] years. 

 

	 	(d)	 This section 8.2 shall survive expiration or termination of this Agreement. All communications between the
Parties and documents relating to this Article 8 shall be deemed “Confidential Information” pursuant to the agreement entered into between the parties hereto and attached as Appendix E.

of the selection or appointment thereof, the Dispute shall be referred to arbitration. The Dispute shall be finally settled by binding arbitration in accordance with this Agreement and the substantive laws of the Commonwealth of Massachusetts,
following the Commercial Arbitration Rules of the American Arbitration Association (“AAA”). The venue for any arbitration hereunder shall be Boston, Massachusetts, United States, and each Party waives the defense of forum non conveniens
and any other defense to personal jurisdiction on grounds of inconvenient forum or otherwise. The award of the arbitration shall be final and binding upon the Parties, and may be entered and enforced in any court of competent jurisdiction. Without
limiting the foregoing, each Party consents to the jurisdiction of the state and federal courts in the Commonwealth of Massachusetts for purposes of any suit to compel mediation or arbitration and any suit to confirm and enforce an arbitration
award. 

  
 25 

	 	(d)	 If a Party believes that it will be irreparably harmed during the arbitration process, such Party may seek
injunctive relief in any Massachusetts court having competent jurisdiction over the Parties and the subject matter to enjoin any breach or violation pending an adjudication on the merits in arbitration. 

 

	 	(e)	 Each Party shall bear its own costs in obtaining the dispute resolution, as outlined above. If a dispute
regarding termination is addressed pursuant to this Article 10.5, including but not limited to by arbitration or mediation, this Agreement shall remain in full force and effect until such dispute is resolved. All applicable statutes of limitation
and time-based defenses (such as estoppel and laches) shall be tolled while any good faith negotiation, arbitration or mediation procedures are pending or ongoing. 

10.6    Challenging Validity. During the Term, Company shall not challenge, and shall restrict its Affiliates and Sublicensees from
challenging, the validity of the Patent Rights and, in the event of any breach of this provision, Hospital shall have the right to terminate this Agreement and any license granted hereunder immediately. In addition, if the Patent Rights are upheld
Company shall reimburse Hospital for its legal costs and expenses incurred in defending any such challenge. 
 10.7    Termination by
Company. Company shall have the right to terminate this Agreement, on a territory by territory basis, by giving [***] days advance written notice to Hospital and, subject to Section 10.10, upon such termination shall immediately cease all
use and Sales of Licensed Products and all uses of Processes in such territory. 
 10.8    Effect of Termination on Sublicenses.
Any sublicenses granted by Company under this Agreement shall provide for termination or assignment to Hospital of such sublicense in the applicable territory, at the option of Hospital, upon termination of this Agreement (or termination of a
territory, as applicable). 
 10.9    Effects of Termination of Agreement. Upon termination of this Agreement or any of the
licenses hereunder for any reason, final reports in accordance with Section 5 shall be submitted to Hospital and all royalties and other payments, including without limitation any unreimbursed Patent Costs, accrued or due to Hospital as of the
termination date shall become immediately payable in each applicable territory. If this Agreement is terminated pursuant to Sections 10.2, 10.3, 10.4, 10.6, or 10.7 Company shall cease, and shall cause its Affiliates and Sublicensees to cease under
any sublicense granted by Company in such territory, all Sales and uses of Licensed Products and uses of Processes upon such termination in such territory, subject to Section 10.10. The termination or expiration of this Agreement or any
license granted hereunder shall not relieve Company, its Affiliates or Sublicensees of obligations arising before such termination or expiration. If this Agreement expires at the full end of the Term as it is defined in 10.1 above, Company will then
have a perpetual, paid up, royalty-free non-exclusive license under all rights granted under this Agreement to make, have made, use, have used, lease, import and export, offer to sell, sell have sold, produce,
manufacture, distribute and market Licensed Products in the License Field and in the License Territory. 

  
 26 

 10.10    Inventory. Upon early termination of this Agreement in a particular
territory other than for Company default, Company, Company Affiliates and Sublicensees may complete and sell any work-in-progress and inventory of Licensed Products that
exist as of the effective date of termination provided that (i) Company pays Hospital the applicable running royalty or other amounts due on such Net Sales in accordance with the terms and conditions of this Agreement, and (ii) upon
the full termination of this Agreement, Company, Company Affiliates, and Sublicensees shall complete and sell all work-in-progress and inventory of Licensed Products
within [***] months after the effective date of termination. Upon expiration of this Agreement, Company shall pay to Hospital the royalties set forth in Section 4.5(a) for Sales of any Licensed Product that was in inventory or was a work-in-progress on the date of expiration of the Agreement. 

11.    COMPLIANCE WITH LAW 

11.1    Compliance. Company shall have the sole obligation for compliance with, and shall ensure that any Affiliates and
Sublicensees comply with, all government statutes and regulations that relate to Licensed Products and Processes, including, but not limited to, those of the Food and Drug Administration and the Export Administration, as amended, and any applicable
laws and regulations of any other country in the License Territory. Company agrees that it shall be solely responsible for obtaining any necessary licenses to export, re-export, or import Licensed Products and

12.    MISCELLANEOUS 

12.1    Entire Agreement. This Agreement constitutes the entire understanding between the Parties with respect to the subject
matter hereof and this Agreement shall supersede and replace, in its entirety, the Exclusive Option Agreement (effective on January 20, 2018; BWH Agreement No.: A224945) previously entered into by the Parties hereto. 

12.2    Notices. Any notices, reports, waivers, correspondences or other communications required under or pertaining to this
Agreement shall be in writing and shall be delivered by hand, or sent by a reputable overnight mail service (e.g., Federal Express), or by first class mail (certified or registered), or by electronic mail confirmed by one of the foregoing methods,

12.3    Amendment; Waiver. This Agreement may be amended and any of its terms or conditions may be waived only by a written
instrument executed by an authorized signatory of the Parties or, in the case of a waiver, by the Party waiving compliance. The failure of either Party at any time or times to require performance of any provision hereof shall in no manner affect its
rights at a later time to enforce the same. No waiver by either Party of any condition or term shall be deemed as a further or continuing waiver of such condition or term or of any other condition or term. 

12.4    Binding Effect. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the Parties hereto
and their respective permitted successors and assigns. 
 12.5    Assignment. Company shall not assign this Agreement or any of
its rights or obligations under this Agreement without the prior written consent of Hospital. Notwithstanding the foregoing, no such consent will be required to assign this Agreement (i) if Company has fulfilled its diligence obligations as set
forth in Section 3.1 and (ii) such assignment is in connection with the disposition or transfer of all, or substantially all, of its assets relating to this Agreement whether by sale, merger, operation of law or otherwise is
to (a) to a publicly traded company or an entity having assets in excess of [***]U.S. dollars ($[***]) or (b) to an Affiliate of Company with assets in excess of [***]U.S. dollars ($[***]), provided, however, there shall be
no such asset qualification if the Affiliate is a wholly owned subsidiary of the Company. In either of the foregoing each such Affiliate, successor, or purchaser shall agree in writing to be bound by the terms of this Agreement at the time of such
assignment. Company shall notify Hospital in writing of any such assignment and provide a copy of the assignment documents to Hospital within [***] days of such assignment. Further, if Company is acquired or merged with a Third Party prior to
completion of the Phase 1 Clinical Trial in Glioma patients, Company’s successor or purchaser shall notify Hospital in writing of their intention to: (i) continue with the Phase 1 Clinical Trial; and (ii) pursue a
successive clinical trial of Licensed Product within [***] days of such assignment. If Company’s successor or purchaser notifies Hospital within such [***]day period that it does not intend to continue with the Phase 1 Clinical Trial and/or
pursue a successive clinical trial of Licensed Product, then such notice may serve as grounds for termination of this Agreement pursuant to Section 10.4. Failure of an assignee to agree to be bound by the terms hereof shall be grounds
for termination of this Agreement pursuant to Section 10.4. Finally, neither any rights granted under this Agreement nor any sublicense may be assigned by any Sublicensee (except pursuant to a sale of substantially all of their assets)
without the prior written consent of Hospital, such consent not to be unreasonably withheld. 

  
 28 

 12.6    Force Majeure. Neither Party shall be responsible for delays resulting
from causes beyond the reasonable control of such Party, including without limitation, fire, explosion, flood, war, sabotage, strike or riot, provided that the nonperforming Party uses Commercially Reasonable Efforts to avoid or remove such causes
of nonperformance and continues performance under this Agreement with reasonable dispatch whenever such causes are removed. 

12.7    Use of Name. Neither Party shall use the name of the other Party or of any trustee, director, officer, staff member,
employee, student or agent of the other Party or any adaptation thereof in any advertising, promotional or sales literature, publicity without the prior written approval of the Party or individual whose name is to be used, except as required by law
or regulation. For Hospital, such approval shall be obtained from Hospital’s Public Affairs Office. Notwithstanding the foregoing, Company may disclose the existence of this Agreement with bona fide and potential or existing investors, provided
that it shall do so under written terms of confidentiality at least as protective of Hospital as those set forth in Appendix E, and provided further that Company shall be responsible for strict compliance by such investors with the terms of this
Agreement and any breach thereof. 
 12.8    Governing Law. This Agreement shall be governed by and construed and interpreted in
accordance with the laws of the Commonwealth of Massachusetts, excluding with respect to conflict of laws, except that questions affecting the construction and effect of any patent shall be determined by the law of the country in which the patent
shall have been granted. Each Party agrees to submit to the exclusive jurisdiction of the Superior Court for Suffolk County, Massachusetts, and the United States District Court for the District of Massachusetts with respect to any claim, suit or
action in law or equity arising in any way out of this Agreement or the subject matter hereof. 
 12.9    Hospital Policies.
Company acknowledges that Hospital’s employees and medical and professional staff members and the employees and staff members of Hospital’s Affiliates are subject to the applicable policies of Hospital and such Affiliates, including,
without limitation, policies regarding conflicts of interest, intellectual property and other matters. Company shall provide Hospital with any agreement it proposes to enter into with any employee or staff member of Hospital or any of
Hospital’s Affiliates for Hospital’s prior review and shall not enter into any oral or written agreement with such employee or staff member which conflicts with any such policy. Hospital shall provide Company, at Company’s request,
with copies of any such policies applicable to any such employee or staff member. 
 12.10    Severability. If any provision(s)
of this Agreement are or become invalid, are ruled illegal by any court of competent jurisdiction or are deemed unenforceable under then current applicable law from time to time in effect during the term hereof, it is the intention of the parties
that the remainder of this Agreement shall not be affected thereby. It is further the intention of the Parties that in lieu of each such provision which is invalid, illegal or unenforceable, there be substituted or added as part of this Agreement a
provision which shall be as similar as possible in economic and business objectives as intended by the Parties to such invalid, illegal or enforceable provision, but shall be valid, legal and enforceable. 

  
 29 

 12.11    Survival. In addition to any specific survival references in this
Agreement, Sections 1, 2.4, 4.6, 4.7, 5.3, 5.4, 5.5, 5.6, 6.5, 8.1, 8.2, 9.2, 9.3, 10.9, 10.10, 12.1, 12.2, 12.3, 12.7, 12.8, 12.10, 12.11, 12.12 and 12.13 shall survive termination or expiration of this Agreement. Any other rights,
responsibilities, obligations, covenants and warranties which by their nature should survive this Agreement shall similarly survive and remain in effect. 

12.12    Interpretation. The parties hereto are sophisticated, have had the opportunity to consult legal counsel with respect to
this transaction and hereby waive any presumptions of any statutory or common law rule relating to the interpretation of contracts against the drafter. 

12.13    Headings. All headings are for convenience only and shall not affect the meaning of any provision of this Agreement. 

12.14    Counterparts; Facsimile; Electronic Mail. The Agreement may be executed in counterparts and delivered by facsimile or
electronic mail with the same effect as an original.

 Appendix E 

CONFIDENTIALITY TERMS AND CONDITIONS 

1.    Definition of Confidential Information. “Confidential Information” means any information, including but not limited
to data, techniques, protocols or results, or business, financial, commercial or technical information, disclosed by one Party (each a “Discloser” as applicable) to the other Party (each a “Recipient” as applicable) in connection
with the terms of that certain Exclusive License Agreement dated September 15, 2020 (the “Agreement”) and identified as confidential at the time of disclosure (the “Purpose”). Hospital’s Confidential Information shall
also include all information disclosed by Hospital to Company in connection with the Patent Rights. Capitalized terms used in this Appendix that are not otherwise defined herein have the meanings ascribed in the Agreement to which this Appendix is
attached and made a part thereof. 
 2.    Exclusions. “Confidential Information” under this Agreement shall not
include any information that (i) is or becomes publicly available through no wrongful act of Recipient; (ii) was known by Recipient prior to disclosure by Discloser, as evidenced by tangible records; (iii) becomes known to Recipient
after disclosure from a Third Party having an apparent bona fide right to disclose it; (iv) is independently developed or discovered by Recipient without use of Discloser’s Confidential Information, as evidenced by tangible records; or
(v) is disclosed to another party by Discloser without restriction on further disclosure. The obligations of confidentiality and non-use set forth in this Agreement shall not apply with respect to any
information that Recipient is required to disclose or produce pursuant to applicable law, court order or other valid legal process provided that Recipient promptly notifies Discloser prior to such required disclosure, discloses such information only
to the extent so required and cooperates reasonably with Discloser’s efforts to contest or limit the scope of such disclosure. 

3.    Permitted Purpose. Recipient shall have the right to, and agrees that it will, use Discloser’s Confidential Information

need-to-know basis to its and its Affiliates employees, staff members and agents (“Receiving Individuals”) who are directly participating in the Purpose and
who are informed of the confidential nature of such information, provided Recipient shall be responsible for compliance by Receiving Individuals with the terms of this Agreement and any breach thereof. Each Party further agrees not to use the name

advertising, promotional or sales literature, publicity or in any document employed to obtain funds or financing without the prior written approval of the Party or individual whose name is to be
used, in the case of Hospital such approval to be given by the Public Affairs Department. This Section 4 shall survive termination or expiration of the Agreement. 

5.    Right to Disclose. Discloser represents that to the best of its knowledge it has the right to disclose to each Recipient all
of Discloser’s Confidential Information that will be disclosed hereunder. 
 6.    Ownership. Subject to the terms of the

the purpose of determining Recipient’s legal obligations hereunder. 
 7.    No License. Nothing in this Appendix E shall be
construed as granting or conferring, expressly or impliedly, any rights by license or otherwise, under any patent, copyright, or other intellectual property rights owned or controlled by Discloser relating to Confidential Information, except as
specifically set forth in the Agreement. 
 8.    Remedies. Each Party acknowledges that any breach of this Agreement by it may
cause irreparable harm to the other Party and that each Party is entitled to seek injunctive relief and any other remedy available at law or in equity. 

9.    General. These confidentiality terms and conditions, along with the Agreement, contain the entire understanding of the
