for Dr. Zorko and University to comply with their Sponsor- Investigator responsibilities;

1

NOW,

THEREFORE, the Parties agree as follows:

1. Sponsor-Investigator.

Sponsor-Investigator shall be considered the sponsor of the Research Program and the Study.

Sponsor-Investigator is responsible for the overall conduct of the Study at the University.

Sponsor-Investigator both initiated and will conduct the Study in accordance with Applicable

Laws (defined below), this Agreement and the Protocol (defined below). If Sponsor-Investigator

is unable to continue to serve in that role and a successor acceptable to both University

and Company is not available, this Agreement may be terminated in accordance with Section

5.

2. Compliance

with Laws. Company and University, including their affiliates and contractors, and the

Sponsor-Investigator shall comply with and conduct all aspects of the Research Program and

the Study in compliance with all applicable federal, state, and local laws and regulations,

including the Federal Food, Drug, and Cosmetic Act (FDCA) (21 USC 301 et seq.) and

regulations issued by the U.S. Food and Drug Administration (“FDA”) including,

but not limited to, 21 CFR Part 312 (Investigational New Drug Application), 21 CFR 50 (Protection

of Human Subjects), 21 CFR 54 (Financial Disclosure by Clinical Investigators), 21 CFR 56

(Institutional Review Boards), regulations pertaining to clinical trials registration and

submission of results provided in 42 CFR 11, and all other generally accepted standards of

good clinical practice as adopted by current FDA regulations and statutes and regulations

of the U.S. Government relating to exportation of technical data, computer software, laboratory

prototypes, and other commodities as applicable to academic institutions (collectively, “Applicable

Laws”). University and Sponsor-Investigator will only allow individuals who are appropriately

trained and qualified to assist in the Research Program and the conduct and oversight of

the Study.

3. Study.

University agrees to conduct the Study in accordance with Applicable Laws, this Agreement

and the study protocol (“Protocol”) which has been written by Sponsor-Investigator

and approved in writing by University and the Company. Sponsor-Investigator shall apply for

approval to conduct the Study with University’s Institutional Review Board (“IRB”)

or an independent Institutional Review Board approved by the University and the Company in

writing. University shall not allow the Study to be initiated until such approval is obtained,

and University and the Company are provided with a final written copy of the IRB approval

letter for the Study. University’s right to conduct the Study, including enrollment

of the Study subjects, is expressly conditioned upon the approval of the reviewing IRB. University

shall cooperate with Sponsor-Investigator in preparing and filing the Protocol, informed

consent form, and other required information with the IRB. Changes to the Protocol require

the prior written approval of the IRB. University shall be responsible for obtaining an informed

consent which complies with all Applicable Laws signed by or on behalf of each human subject

prior to the subject’s participation in the Study.

4. Study

Budget. The Parties agree that Study funding and resources provided by Company shall

be allocated to the Study as outlined in the Budget attached hereto as Exhibit B and

without first receiving the Company’s prior written consent for such increase in expenditure.

All changes to the Study Budget require the Company’s prior written approval.

2

5. Term

and Termination.

5.1

The term of this Agreement shall commence upon the Effective Date and terminate upon the completion of the Parties’ Study-related

activities under this Agreement, unless terminated early as further described in this Section 5.

5.2.

Either Party has the right to terminate the Study upon thirty (30) days prior written notice to the other Party. The Study may be terminated

immediately upon written notice at any time for any reason by the University or Company when, in its reasonable judgment or that of the

Sponsor- Investigator, the IRB, the FDA or other applicable regulatory authority, it is determined to be inappropriate, impractical,

or inadvisable to continue, in order to protect the Study subjects’ health, welfare, and safety. If for any reason Sponsor-Investigator

becomes unavailable to direct the performance of the Study under this Agreement, University shall promptly notify Company in writing.

If the Parties are unable to identify a mutually acceptable successor within thirty (30) days following University’s notice to

the Company, this Agreement may be terminated by either Party upon thirty (30) days written notice.

5.3.

Notwithstanding the above, either Party may, in addition to any other available remedies, terminate this Agreement immediately upon written

notice to the other Party if the other Party materially breaches this Agreement, provided that the breaching Party fails to remedy such

material breach within thirty (30) days after its receipt of written notice thereof; provided, however, that the cure period shall be

suspended during any time that a Party seeks resolution of a dispute as to whether an alleged breach occurred pursuant to any dispute

resolution mechanism under this Agreement.

5.4.

In the event that this Agreement is terminated prior to completion of the Study, for any reason, University shall furnish to Company

any required final report for the Study in a format mutually agreed upon by the Parties. Promptly following any such termination, University

will provide to Company copies of Study Data collected pursuant to the Protocol.

5.5.

If this Agreement is terminated early by either Party, University shall be reimbursed for all work completed, on a pro rata basis, and

out-of-pocket, reasonable costs of bringing the Study to termination actually incurred by University through the date of termination,

and for reasonable, non- cancelable commitments actually incurred by University in the performance of the Study through that date as

set forth in the Study Budget. Upon receipt of notice of termination, University will use reasonable efforts to reduce or eliminate further

costs and expenses and will cooperate with Company to provide for an orderly wind-down of the Study. Upon expiration or earlier termination

of this Agreement, University shall return to the Company all unused Study Drug and Company Confidential Information. The following sections

shall survive the expiration or earlier termination of this Agreement: Sections 2, 5.5, 6, 11, 13, 17, 18, 21, 22, 23, 24, 25, 26, 27,

28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 43, 44, 45, and 46.

3

6. Study

Drug. Company agrees to provide within a commercially reasonable time period, at no cost

to University, sufficient quantities of the Study Drug to conduct the Study in accordance

with the Protocol. University shall handle, store, and administer or dispense the Study Drug

in accordance with the Protocol, this Agreement, Applicable Laws and the Company’s

written instructions for the conduct of the Study. Company and its contractors that perform

drug manufacturing for the Study, are responsible for assuring that the Study Drug is manufactured

in compliance with current good manufacturing practices (21 USC 351(a)(2)(B)) (“CGMP”).

University shall maintain accurate and complete records of the shipment, delivery, receipt

and disposition of the Study Drug in accordance with the Protocol, this Agreement, Applicable

Laws and the Company’s written instructions.

7. Batch

Documentation. Company shall provide to University the following documents that Company

receives from the supplier of the Study Drug (the “Supplier”): (a) records that

document the Supplier’s steps and processes utilized in the manufacture of the Study

Drug; (b) the documents that are required under the applicable quality technical agreement;

(c) the certificate of analysis for the Study Drug; and

(d)

the certificate of compliance for the Study Drug. Upon reasonable written request by University, Company shall request, and make reasonable

efforts to obtain, additional records and documents from the Supplier to provide further assurance of conformance with CGMP; provided,

however, Company shall not be obligated to provide additional records and documents unless such records and documents are received from

the Supplier.

8. Acceptance

Mechanism. University may reject any quantity of nonconforming Study Drug that has been

delivered to University hereunder by delivering written notice to Company within thirty (30)

days of delivery of such nonconforming Study Drug to Company. Any batch of Study Drug for

which a notice of non-conformance is not delivered within such thirty (30) day period will

be deemed to be accepted by University upon the expiration of such period, provided that

University will have three (3) months from the date that a batch of Study Drug is accepted

to reject the Study Drug by reason of a hidden or latent defect existing at the time of delivery

that was not discoverable upon commercially reasonable physical inspection and testing of

the Study Drug (a “Latent Defect”), and University must notify Company in writing

of such Latent Defect within three (3) business days of such discovery. However, if the Study

Drug expires prior to the three (3) month period in the foregoing sentence, University will

have until one (1) week prior to the expiration of the Study Drug to reject the Study Drug

because of a Latent Defect. The notice must detail the nature of the Latent Defect, and based

on information reasonably available at the time, how the nonconformance could have resulted

from the Supplier’s manufacturing of the Study Drug.

4

9. Independent

Testing. If the Supplier does not agree with University’s rejection of any Study

Drug as nonconforming Study Drug (as such is communicated to the Supplier by Company on behalf

of University), then the Supplier, Company and University shall engage an independent person

or persons of recognized standing in the industry with respect to the development and CGMP

manufacture of biologic therapeutics, qualified to resolve a dispute between the Supplier,

Company and University, and who is a recognized expert in the field of NK cell biology and

the development of NK cell engagers (a “Third Party Expert”) to resolve the dispute.

If the dispute concerns the Study Drug’s conformance to the specifications or the Supplier’s

adherence to the CGMP manufacturing process, the Supplier, Company and University will submit

the master batch records, batch production records, specifications, applicable statement

of work, and other information relevant to the dispute (including a representative sample

of the Study Drug, if necessary) to an independent testing laboratory mutually agreed to

by the Supplier, Company and University. If the dispute concerns the Supplier’s adherence

to CGMP, the Supplier, Company and University will submit the master batch records, batch

production records, specifications, applicable statement of work, and other information relevant

to the dispute to a CGMP consultant mutually agreed to by the Supplier, Company and University.

The findings of the Third Party Expert shall be final and binding on the Supplier, Company

and University, absent fraud or manifest error. In making its determination, the Third Party

Expert shall consider the information supplied by the Supplier, Company and University, the

Supplier’s acts and omissions, the Company and University’s acts and omissions,

and any deficiencies in Company’s technology, components, equipment, raw materials,

and the CGMP manufacturing process. The Third Party Expert shall use the test and analysis

methods contained in the CGMP manufacturing process and the applicable statement of work

when conducting their analysis. If the Third Party Expert determines that the Study Drug

was conforming, University shall pay the fees and expenses of the Third Party Expert. If

the Third Party Expert makes any other determination, including, but not limited to, that

the results are inconclusive or that the Study Drug was a non-conforming batch but not as

a result of the Supplier’s defective CGMP manufacturing, University shall pay the fees

and expenses of the laboratory or consultant and will have no remedy against the Supplier

or Company for the non-conforming Study Drug.

10. Facilities

and Equipment. Company including its affiliates and contractors, shall at its sole cost

and expense, maintain the manufacturing facility and all related quality documentation, processes

and systems used in connection with the Study Drug in compliance with FDA and other CGMP

quality standards and operate in compliance with all applicable environmental, occupational

health and safety laws and regulations. Each Party shall secure and maintain, at its sole

cost and expense, any registrations, approvals, permits, authorizations, and licenses as

are required by Applicable Laws for such Party to perform its obligations under this Agreement.

11. Storage.

University shall store and handle all materials and products in accordance with Applicable

Laws, the specifications and quality standards for such Study Drug, including segregating

Study Drug for which final release has not been provided or otherwise not accepted by University.

12. Packaging

and Labeling. Company will package and label Study Drug in accordance with the University’s

IND, and will comply with all reasonable University instruction regarding the packaging and/or

labeling of Study Drug, including timely updating any such packaging and/or labeling for

the Study Drug. Company will use only University approved packaging and labeling for all

Study Drug delivered hereunder and shall not modify any packaging or labeling for any such

Study Drugs without University’s prior written consent.

13. Qualified

Personnel. University and Sponsor-Investigator shall only assign personnel who are trained,

qualified, and experienced to perform the Study, and University and Sponsor-Investigator

shall ensure that all personnel assisting with the performance of the Study comply with all

provisions of this Agreement.

5

14. Change

Control. If either Party desires to implement a change to the manufacturing process,

including any testing method with respect to any Study Drug or any specifications, or if

University is required by FDA or any other governmental authority to implement any such change,

the Parties will discuss in good faith the potential effect on the identity, strength, quality,

purity, or potency of the Study Drug, and will agree in writing prior to the implementation

of any such change to the manufacturing process. Unless agreed upon by the Parties in writing,

Company has no obligation to provide new Study Drug incorporating any change of the manufacturing

process.

15. Deviations

and Nonconformances. Deviations and nonconformances including OOS results and unexplained

discrepancies shall be investigated and documented and retained as part of the batch documentation

for the batch of Study Drug affected according to the applicable written procedures. Company

shall notify University in writing promptly of any deviation or nonconformance, where such

finding is classified as serious or critical based on the risk of potential adverse impact

on Study Drug quality and patient safety, but no longer than one (1) business day after Company’s

knowledge of the event, including insofar as the Company determines the Study Drug is subject

to such deviations or nonconformances, including OOS results, after delivery to University.

Company

shall investigate all such deviations and nonconformances, and shall timely take corrective action to avoid future occurrences. Company

shall use commercially reasonable efforts to complete its investigation of any deviations and nonconformances including confirmed OOS

results within thirty (30) days of commencement, and will maintain a written justification where such investigation requires a longer

period of time to complete.

16. Nonconforming

Drug. Subject to Sections 8, 9, and 15 above, if either Party becomes aware that any

batch or shipment of Study Drug does not conform to the approved specifications for Study

Drug, such Party shall notify the other Party in writing as soon as reasonably practicable

but in no event later than three

(3)

business days of becoming aware of such nonconformance. Any batch or shipment of nonconforming Study Drug shall be handled as follows:

(a) any such Study Drugs held in inventory by Company shall not be shipped; and (b) any previously shipped nonconforming Study Drug held

in stock by either Party or its affiliate shall be segregated and maintained in a “hold” or “quarantine” status,

and in the case of each of clauses (a) and (b), such Study Drugs shall not be released or further distributed until the Parties have

completed any investigations related to such nonconforming Study Drug.

17. Retention

Samples. Company shall ensure adequate representative samples are retained for each batch

or lot of Study Drug and of delivered materials used in manufacturing, packaging, and labeling

the Study Drug to enable subsequent testing of such Study Drug, in accordance with the University’s

IND and University’s instruction. Company shall accurately label such samples to identify

the batch of Study Drug and shall store all such samples as appropriate in accordance with

the applicable specifications. Company shall retain all samples of the Study Drug or materials

and intermediates therein for the longer of (a) one (1) year following the indicated expiry

date of such Study Drug and (b) such longer period of time as may be required by Applicable

Laws.

18. Stability

Testing. Company will maintain, retain, and store sufficient retention samples of Study

Drug as necessary to perform applicable stability tests in conformance with CGMP and as required

by FDA or any other governmental authority, in accordance with the specifications for such

Study Drug and this Agreement. Retention samples shall be retained for the longer of (a)

the expiry date of the applicable Study Drug plus one (1) year, or (b) such longer period

of time as may be required by Applicable Laws.

6

19. Complaints

and Adverse Events. As between the Parties, Company including its affiliates and contractors

engaged in manufacturing the Study Drug, shall establish and maintain guidelines and procedures

for the receipt, investigation, recordation, communication, and exchange (as between the

Parties) around product quality complaints or adverse events and any other information concerning

the quality or safety of the Study Drug. Each Party shall immediately notify the other Party

of any product complaints or adverse events received by such Party concerning any Study Drug

supplied hereunder. Company shall investigate all such complaints and adverse events and,

where necessary and appropriate, shall take corrective action to avoid future occurrences.

The Parties shall investigate any reports of nonconforming Study Drug or any other product

complaint or adverse events in order to assess, as applicable, the potential risk of impact

to the relevant Study Drugs and to determine the validity of such product complaint or adverse

event. Company shall notify University immediately of any difficulty in manufacturing, packaging,

labeling, or delivery any Study Drug in accordance with their applicable specifications,

Applicable Laws, or the terms and conditions of this Agreement. University may, at its option,

investigate the cause of any failure itself. Company will complete any quality investigation

according to established written procedures, and shall provide University with a written

report summarizing the results of Company’s investigation. Company shall cooperate

with University in handling such nonconforming products, complaints, or adverse events, and

shall take reasonable actions and provide any additional assistance and information as University

reasonably requests, including promptly investigating and conducting any follow-up with regard

to such nonconforming products, product complaints, or adverse events, and providing any

data, information, or other assistance that University may reasonably require in connection

therewith.

20. Recovery

or Withdrawal. Company shall keep University informed of any notification or other information,

whether received directly or indirectly, which might affect the safety or effectiveness of

any Study Drug or which might result in product recovery or withdrawal in connection with

the Study Drug. If either Party in good faith determines that a product recovery or field

action involving any Study Drug is warranted, such Party shall immediately notify the other

Party and shall advise such other Party of the reasons underlying its determination that

such product recovery or withdrawal if warranted; provided, however, that University shall

retain full authority and responsibility for instituting any recovery or field action of

any Study Drug and corresponding with the applicable governmental authorities. Company will

cooperate with University in connection with any such recovery or withdrawal, and promptly

provide to University, any data, information, or assistance as reasonably requested by University

in connection therewith.

21. Safety

Study shall be permitted to present at symposia, national or regional professional meetings and to publish in journals, theses or dissertations,

or otherwise of their own choosing, methods and results of the Study (each, a “Publication”). University shall have the final

authority to determine the scope and content of any University Publication; provided, however, that University shall provide copies of

any proposed Publication at least thirty (30) days in advance of the Publication to Company to review and object to such Publication

because such draft either contains information deemed to be Confidential Information under the provisions of Section 27 of this Agreement,

or reveals information that if published within thirty (30) days would have an adverse effect on a patent application in which Company

owns full or part interest, or intends to obtain an interest from University pursuant to this Agreement. In the event that Company notifies

the University in writing that the proposed Publication contains Company’s Confidential Information, the University shall remove

any Company Confidential Information from the draft prior to such Publication. In the event Company requests in writing a delay in Publication

to file for patent protection, the University and the Sponsor- Investigator shall refrain from making such Publication for a maximum

of ninety (90) days from the receipt of such objection, and Company shall indicate with specificity to what manner and degree University

may disclose said information during the ninety (90) day period.

24.2

Company shall have the right to make Publications and issue press releases regarding the Study and the Study results (each, a “Company

Publication”). Company shall have the final authority to determine the scope and content of any Company Publication; provided,

however, that Company shall provide copies of any proposed Company Publication that includes the results of the Study at least thirty

(30)

days in advance of the Company Publication to University to review and object to such Company Publication because such draft either contains

information deemed to be Confidential Information under the provisions of Section 27 of this Agreement, or reveals information that if

published within thirty (30) days would have an adverse effect on a patent application in which University owns full or part interest.

In the event that University notifies the Company in writing that the proposed Company Publication contains University’s Confidential

Information, the Company shall remove any University Confidential Information from the draft prior to such Company Publication. In the

event University requests in writing a delay in the proposed Company Publication to file for patent protection, the Company shall refrain

from making such Company Publication for a maximum of ninety (90) days from the receipt of such objection, and University shall indicate

with specificity to what manner and degree Company may disclose said information during the ninety (90) day period.

24.3

Publication by either Party to this Agreement shall give proper credit to the other Party for the cooperative character of the Study;

provided that, for any such Company Publication, Company shall obtain prior written approval pursuant to Section 35 below, to use the

name, logos and other marks and trade names of University, or of any individual member of University staff, including Sponsor- Investigator

and University personnel involved with the Research Program. For clarity, and notwithstanding the foregoing, Company may, without prior

written approval of the University, state in a Publication in a factual, non-misleading manner that the Study is being conducted at the

University.

9

25. Inspection.

University shall notify Company in writing (including via electronic mail) of any proposed

visit or inspection by any governmental authority if such visit or inspection has the potential

to impact the Study. University shall in good faith cooperate with the governmental authority

in the conduct of such inspection and provide such access to any locations, personnel or

records as requested by such governmental authority. University shall provide Company with

summaries of all reports, documents or correspondence with respect to any governmental authority

requests or inspections of the facility related to the Study, as well as a copy of each such

report, document or correspondence, which copies shall be provided promptly to Company. Company

will be provided an opportunity to review and provide comments to any regulatory correspondence

or other request, and University will provide Company with any proposed corrective actions,

responses and other changes arising out of such review or inspection by such governmental

authority. University shall cause Sponsor-Investigator and its permitted subcontractors to

comply with this Section 25.

26. Documentation.

University shall maintain complete, legible, and accurate Study records as required by Applicable

Laws and Company’s instruction. Upon and in accordance with Company’s request,

University shall provide Company with complete, legible, and accurate copies of any such

requested Study records. Without limiting the foregoing, Study records shall be available

at all reasonable times for review and inspection by Company for verification of compliance

with this Agreement. Prior to destroying any such Study records, University shall provide

Company with at least thirty (30) days written notice, and upon Company’s request within

such thirty (30) day period, shall cooperate with Company to transfer over any Study records

to Company or its designee in accordance with Company’s instructions and at Company’s

reasonable and documented expense.

27. Confidentiality.

27.1

For purposes of this Agreement, “Confidential Information” means written or tangible information disclosed by or on behalf

of either Party (the “Disclosing Party”) to the other Party (the “Receiving Party”) or its Representatives (including

Sponsor-Investigator), which at the time of disclosure is clearly and conspicuously labeled “Confidential” or “Proprietary”.

Confidential Information shall also include oral and visual disclosures which are identified as confidential at the time of such disclosures

and which are confirmed and summarized within fifteen (15) days of the disclosure by the Disclosing Party in a writing that sets forth

the substance of the Confidential Information disclosed. Notwithstanding the foregoing, information disclosed by the Disclosing Party

pursuant to this Agreement that is not identified as “Confidential” or “Proprietary” will nevertheless be treated

as Confidential Information by the Receiving Party if a reasonable person knowledgeable in the industry and field would, based upon the

nature of the information or the circumstances surrounding its disclosure, consider such disclosure to be confidential and/or proprietary.

The Protocol shall be considered University’s Confidential Information regardless of being labeled as such. The Parties agree to

maintain confidentiality of the Confidential Information during the term of this Agreement, including any renewal periods, and for a

period of three (3) years from the effective termination or expiration date of this Agreement (except for trade secrets, which shall

be held in confidence for so long as they are protected under applicable law). Neither Party shall use said Confidential Information

for any purpose other than those purposes specified in this Agreement. The Parties may disclose Confidential Information to their officers,

directors, employees, agents and representatives (collectively, “Representatives”) requiring access thereto for the purposes

of this Agreement provided, however, that prior to making any such disclosures each such Representative shall be apprised of the duty

and obligation to maintain Confidential Information in confidence and not to use such information for any purpose other than in accordance

with the terms and conditions of this Agreement and shall be bound in writing by obligations of confidentiality and non-use at least

as stringent as the obligations set forth herein. Each Party shall be responsible for any breach of this Section 27 by its Representatives.

10

27.2

Nothing contained herein will in any way restrict or impair either Party’s right to use, disclose, or otherwise deal with any Confidential

Information which the Receiving Party can demonstrate through written documentation:

27.2.1

At the time of its receipt, is generally available in the public domain, or thereafter becomes available to the public through no act

of the Receiving Party;

27.2.2

Was independently known prior to receipt thereof, or made available to such Receiving Party as a matter of lawful right by a third party;

27.2.3

Is received without obligation of confidentiality from a third party; or

27.2.4

Is developed independently by the Receiving Party without use of or reference to the Confidential Information of the Disclosing Party.

In

the event that a Party is required by law (including the Minnesota Government Data Practices Act), and/or regulation or court order to

disclose Confidential Information, the Party required to make such disclosure shall notify the other Party in writing to allow that Party

to assert whatever exclusions or exemptions may be available to it under law. In the event that a protective order or other appropriate

remedy is not obtained by the Disclosing Party, the Receiving Party shall only furnish that portion of the Confidential Information that

is legally required to be disclosed.

28. Intellectual

Property.

28.1

It is recognized and understood that certain existing inventions and technologies are the separate property of University or Company

and are not affected by this Agreement, and neither Party shall have any claims or rights in such separate inventions. University agrees

that any new patentable inventions, developments, or discoveries resulting from the Study (“Inventions”) shall be promptly

disclosed in writing to Company. Any Inventions developed in the course of the Study conducted hereunder shall be owned by the Party

whose Representatives make or generate the Invention, in accordance with the Parties’ respective intellectual property policies

and procedures. Jointly made or generated Inventions shall be jointly

owned by the Parties. In all cases, inventorship shall be determined in accordance with United States patent law.

11

28.2

Company is hereby granted, without option fee other than consideration of the Study sponsored herein and the reimbursement to University

for patent expenses incurred prior to or during the option period, an option to acquire an exclusive, worldwide, royalty bearing license

to any Invention owned by University (“University Inventions”), which option shall extend for no more than ninety (90) days

after Company’s receipt of an Invention disclosure from University in writing (“Option Period”). The Parties shall

use their reasonable efforts to negotiate in good faith, for a period not to exceed ninety (90) days after Company’s exercise of

such option, a license agreement reasonably satisfactory to both Parties (“Negotiation Period”). In the event Company fails

to exercise its option within the Option Period, or the Parties fail to reach agreement on the terms of such license within the Negotiation

Period, University shall have no further obligation to Company under this Agreement with regard to such Invention.

28.3

Regardless of whether Company acquires a license to a University Invention, University retains an irrevocable, world-wide, royalty-free,

non-exclusive right to use the University Inventions for non-commercial teaching, research and educational purposes. The University shall

have the right to sublicense its rights under this section to one or more non-profit academic or research institutions for non-commercial

purposes.

29. Insurance

and Indemnification.

29.1

Each Party represents that it has and will continue to have at least the following levels of insurance or self-insurance during the term

of this Agreement: (i) as to the University, Workers’ Compensation in statutory compliance with Minnesota State Law; and (ii) as

to both Parties, General Liability Insurance in an amount not less than one million dollars ($1,000,000) each claim/three million dollars

($3,000,000) each occurrence. University represents that the University and Sponsor- Investigator have and will continue to have Professional

Liability insurance in an amount not less than one million dollars ($1,000,000) each claim/three million dollars ($3,000,000) each occurrence.

Company represents that it has and will continue to have Study Drug Liability insurance or self-insurance in an amount not less than

one million dollars ($1,000,000) per claim/three million dollars ($3,000,000) per occurrence. Certificates of all insurance detailed

above shall be furnished to the other Party upon request.

29.2

Each Party shall be responsible for its own acts and the results thereof and not for the acts of the other Party. Liability of the University

is subject to the terms and limitations of the Minnesota Tort Claims Act, Minnesota Statutes Section 3.736.

29.3

Company shall indemnify, defend, and hold harmless University against any and all third party claims, costs, or liabilities, including

attorneys’ fees and court costs at both trial and appellate levels (collectively, “Claims”), to the extent arising

from (a) a material breach of this Agreement by Company, (b) the gross

negligence or willful misconduct of Company, or (c) a violation of law by Company in connection with Company’s performance under

this Agreement. Section 29.3 shall apply with the provision that (a) University promptly notifies Company in writing after University

receives notice of any Claim and (b) University reasonably cooperates with Company in the defense of any such Claim. Notwithstanding

the foregoing, Company shall not settle or dispose of any such Claim in any manner which would adversely affect the rights or interests

of University without the prior written consent of University, or make any admission of guilt or negligence of University without University’s

prior written consent, which shall not be unreasonably withheld, conditioned or delayed.

12

29.4

Subject to the terms and limits of the Tort Claims Act, Minnesota Statutes Section 3.736, University shall indemnify, defend, and hold

harmless Company against any and all Claims to the extent arising from (a) a material breach of this Agreement by University or Sponsor-Investigator,

(b) the gross negligence or willful misconduct of University, Sponsor-Investigator or their Representatives, or (c) a violation of law

by University, Sponsor-Investigator or their Representatives in connection with University and/or Sponsor-Investigator’s performance

under this Agreement. Section 29.4 shall apply with the provision that (a) Company promptly notifies University in writing after Company

receives notice of any Claim and (b) Company reasonably cooperates with University in the defense of any such Claim. Notwithstanding

the foregoing, University shall not settle or dispose of any such Claim in any manner which would adversely affect the rights or interests

of Company without the prior written consent of Company, or make any admission of guilt or negligence of Company without Company’s

prior written consent, which shall not be unreasonably withheld, conditioned or delayed.

30. Reimbursement.

If a Study subject suffers an adverse reaction, medical illness, or injury which was directly

caused by a Study Drug that was properly administered in accordance with the Protocol and

this Agreement, Company shall reimburse University for the reasonable and necessary expenses

that are actually incurred in the diagnosis and treatment of any Study subject injury (not

covered by 3rd party payers such as Medicare or privacy insurance), including hospitalization,

but only to the extent such adverse reaction, medical illness or injury are not caused by

(i) University’s, Sponsor-Investigator’s or the Study subjects’ negligence

or willful misconduct; (ii) the natural progression of an underlying or pre- existing condition

or events, unless exacerbated by participating in the Study; or (iii) University’s

and/or Sponsor-Investigator’s failure to adhere to and comply with the specifications

of the Protocol and all reasonable written instructions furnished by Company for the use

and administration of any Study Drug used in the Study, provided that deviations from the

Protocol and written instructions resulting from an imminent threat to the health or safety

of a Study subject that does not cause the injury to the Study subject will not disqualify

University from reimbursement under this provision.

31. Disclaimer

of Warranties. Except for Sections 1, 6, 10, and 12 above, neither Party makes any warranties,

express or implied, as to any matter whatsoever, including without limitation, the condition,

originality or accuracy of the research or any invention (s) or product(s), whether tangible

or intangible, conceived, discovered, or developed under this Agreement; or the ownership,

merchantability, or fitness for a particular purpose of the research or any such invention

or product. COMPANY MAKES NO REPRESENTATIONS AND EXTENDS NO WARRANTIES OF ANY KIND, EITHER

EXPRESS OR IMPLIED, WITH RESPECT TO THE STUDY DRUG. THE STUDY DRUG IS PROVIDED “AS-IS”.

32. LIMITATION

OF LIABILITY. IN NO EVENT SHALL EITHER PARTY’S LIABILITY TO THE OTHER PARTY INCLUDE

DAMAGES FOR WORK STOPPAGE, LOST DATA, OR INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES (INCLUDING

LOST PROFIT) OF ANY KIND. EXCEPT FOR EACH PARTY’S OBLIGATIONS UNDER SECTIONS 29.3,

29.4, AND 30, NO PARTY’S LIABILITY TO THE OTHER PARTY UNDER THIS AGREEMENT SHALL EXCEED

THE MONETARY CONSIDERATION DUE OR PAYABLE TO THE UNIVERSITY UNDER THIS AGREEMENT.

13

33. Debarment.

Each Party represents and warrants that neither it nor any of its or its affiliates’

employees or agents performing under this Agreement has ever been, or is currently: (a) debarred

under 21 USC 335a or by any regulatory authority; (b) excluded, debarred, suspended, or otherwise

ineligible to participate in federal health care programs or in federal procurement or non-procurement

programs; (c) listed on the FDA’s Disqualified and Restricted Lists for clinical investigators;

or (d) convicted of a criminal offense that falls within the scope of 42 USC 1320a-7(a),

but has not yet been excluded, debarred, suspended, or otherwise declared ineligible. Each

Party further covenants that if, during the term of this Agreement, it becomes aware that

it or any of its or its affiliates’ employees or agents performing under this Agreement

is the subject of any investigation or proceeding that could lead to that Party becoming

a debarred entity or individual, an excluded entity or individual or a convicted entity or

individual, in each case pursuant to subsections (a) through (d) of this section, such Party

will promptly notify the other Party in writing. Each Party further covenants that if, during

the term of this Agreement, it becomes aware that it or any of its or its affiliates’

employees or agents is the subject of any investigation or proceeding that could lead to

that entity becoming a debarred entity or individual, an excluded entity or individual or

a convicted entity or individual, in each case pursuant to subsections (a) through (d) of

this section, such Party will promptly notify the other Party in writing.

34. Export

Controls. The Parties acknowledge that their activities may be subject to export control

laws and regulations, including, without limitation, the Export Administration Regulations

(15 CFR Parts 730-774) (“EAR”), the International Traffic in Arms Regulations

(22 CFR Parts 120-130) (“ITAR”), and the Foreign Assets Control Regulations (31

CFR Parts 501-598). Except as provided in the following paragraph, each Party will be solely

responsible for its compliance with such export control laws and regulations. Before transferring

any commodity, software, or technical data (collectively, “Items”) subject to

the EAR or ITAR to University, Company must first give notice to University that it intends

to transfer the Items in question. Such notice shall identify the relevant classification

on the Commerce Control List (for EAR Items) or category of the U.S. Munitions List (for

ITAR Items). University shall have the right to decline receipt of Items subject to the EAR

or ITAR. Company shall not transfer Items subject to the EAR or ITAR to University until

University has furnished written confirmation that it (a) will accept the Items, and (b)

either has implemented a technology control plan or has determined that one is not needed.

35. Publicity.

35.1

Company will not use the name, logos and other marks and trade names of University, nor of any individual member of University staff,

without the prior written approval of an authorized representative of University, except where required by law. University will not use

the name, logos and other marks and trade names of Company, nor any Representative of Company, in any publicity, advertising, or news

release without the prior written approval of Company. For clarity, and notwithstanding the foregoing, Company may, without prior written

approval of the University, state in a Publication in a factual, non-misleading

manner that the Study is being conducted at the University.

14

35.2

Pursuant to the University’s Openness in Research Policy (a copy of which may be found at http://www1.umn.edu/regents/policies/academic/Openness_in_Research.pdf)

governing the Parties and research performed under the terms of this Agreement.

35.4

Each Party represents, warrants, and covenants that it will avoid deceptive, misleading or unethical practices and it will make no false

or misleading statements regarding the Product or the Study (or the results thereof).

necessary to protect the safety, rights, or welfare of the Study subjects. Any such changes

must be fully, accurately, and contemporaneously documented in accordance with established

procedures. University shall, within one (1) business day from occurrence, or as otherwise

specified in the Protocol, notify Company in writing of any change from the Protocol, including

be entitled, in addition to any other remedies available at law or in equity, to seek injunctive

or other equitable relief by a court of appropriate jurisdiction.

46. Waiver;

Severability. The failure to enforce any right or provision herein shall not constitute

a waiver of that right or provision. No waiver of any breach, right, or obligation under

this Agreement shall be effective unless in writing and signed by the Party to be charged.

No consent to or waiver of a breach by either Party hereto, whether express or implied, shall

constitute a consent to, waiver of, or excuse for any other, different, or subsequent breach

by such Party. Any of the provisions of this Agreement which are determined to be invalid

or unenforceable in any jurisdiction shall be ineffective to the extent of such invalidity

or unenforceability in such jurisdiction, without rendering invalid or unenforceable the

remaining provisions hereof or affecting the validity or enforceability of any of the provisions

of this Agreement in any other jurisdiction.
