 2.03 Consultation Regarding Reports. MAYO shall review the Reports and promptly inform NILE if MAYO reasonably believes that the
Development or Commercialization plans presented in the Reports are not adequate for a Product. NILE and MAYO will mutually confer, provided, however, notwithstanding anything to the contrary herein, NILE has the final decision-making authority.

 2.04 Receipt of Regulatory Approval. NILE shall notify MAYO within five (5) business days of receiving official notice of any regulatory
approval for any Product. 
 Article 3 - Grant of Rights 
 3.01 Grant of Rights. MAYO grants to NILE an exclusive, world-wide, royalty-bearing license, with the right to sublicense pursuant to Section 3.06, under the Patents and Improvements, and a nonexclusive
right under the Know-How to develop, make, have made, use, sell, import, offer to sell and commercialize Products within the Territory and within the Field. 
 3.02 Reservation of Rights. All rights herein are subject to: (a) the rights and obligations to and requirements of the U.S. government, if any have arisen or may arise, regarding the Patents, including as set
forth in 35 U.S.C. §§200 et al., 37 C.F.R. Part 401 et al. (“Bayh-Dole Act”); and (b) MAYO’s and its Affiliates’ reserved, irrevocable right to practice and have practiced the Patents in connection with MAYO’s
and its Affiliates’ educational, research and non-human clinical programs. NILE agrees to comply with the provisions of the Bayh-Dole Act, including promptly providing to MAYO with information requested to enable MAYO to meet its compliance
requirements and substantially manufacturing Product in the U.S. 
 3.03 All Other Rights Reserved. Except as granted in Section 3.01, or
as otherwise expressly granted herein, no other license is granted by MAYO under any intellectual property rights owned or controlled by MAYO, including any patents, know-how, copyrights, proprietary information, and trademarks. All such rights are
expressly reserved by MAYO. Except as provided herein, NILE acknowledges that in no event will this Agreement be construed as an assignment by MAYO to NILE of any intellectual property rights. 
 3.04 Confidentiality. During the Term, and for a period of five (5) years thereafter, each Party hereto agrees to keep confidential by not disclosing to any
third party any information (i) relating to this Agreement, including the terms and conditions thereof, or (ii) disclosed by one Party (the “Disclosing Party”) to the other (the “Receiving Party”). The Parties may use
this information solely as necessary for complying with the terms and conditions of this Agreement. The obligations of non-disclosure and non-use will not apply when and to the extent such information:

 At MAYO’s request, NILE will cooperate fully with MAYO, except financially, in any legal actions taken by MAYO to protect its rights in the Patents and Know-how
disclosed hereunder. 
 For avoidance of doubt, any violation of the obligations stated in this Section 3.04 constitutes a material breach of this
Agreement. 
 3.05 Availability of Product to MAYO. Once a Product becomes commercially available, to the extent permitted by law and applicable
regulations, NILE will provide Products to MAYO and their Affiliates solely for it and their use for internal research and education programs in the Field at most favored nation pricing (i.e. no more than the lowest price available to
NILE’s commercial customers for the Products for use in the Field). 
 3.06 Sublicensee Actions. NILE may enter into sublicensing agreements
relating to the Patents, Improvements and Know-how. Nile agrees that any sublicense agreement shall (i) contain provisions at least as favorable to MAYO for the protection of MAYO’s rights and the limitation of MAYO’s liability
exposure as the terms of this Agreement, including without limitation with respect to name use, limitation of liability and indemnification, and development and commercialization obligations commensurate in scope as those set forth for Nile in this
Agreement, (ii) to the fullest extent applicable, contain all rights and obligations due to MAYO contained in this Agreement, and (iii) name MAYO as a third party beneficiary. NILE shall (i) be and remain responsible for the
performance by such Sublicensee with the terms of this Agreement, and any action by a Sublicensee that would, if conducted by NILE, be a breach of this Agreement, shall be deemed a breach of this Agreement by NILE, and (ii) ascertain,
calculate, audit and collect all royalties that become payable by such Sublicensee hereunder and take appropriate enforcement action against such Sublicensee for any failure to pay or to properly calculate payments. Any purported sublicense in
violation of this Section 3.06 shall be voidable. 
 Nile shall furnish to MAYO a true and complete copy of each sublicense agreement
and each amendment thereto, within thirty (30) days after the sublicense or amendment has been executed, which copy shall be the Confidential Information of Nile.

following: 

 “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933,
AS AMENDED (THE “ACT”) OR ANY STATE SECURITIES OR “BLUE SKY LAWS”, AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED ABSENT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR COMPLIANCE WITH RULE 144

to be paid by MAYO on funds received from or on behalf of NILE.

the administration or enforcement of this Agreement, including collection of payments, following such failure to pay. The acceptance of any payment, including of such interest shall not foreclose MAYO from exercising any other right or seeking any
other remedy that it may have as a consequence of the failure of NILE to make any payment when due. 
 4.11 Material Breach. It shall be a material
breach of this Agreement if NILE shall fail to make any payment pursuant to Article 4 of this Agreement when such payment is due or by the end of any applicable cure period. 
 Article 5 - Accounting and Reports 
 5.01 Royalty Reports and Payments. NILE will, after

 5.02 Audit Rights. NILE agrees to
maintain the Records and to require any permitted Sublicensees to maintain the Records. “Records” mean complete and accurate records showing clearly all transactions that are relevant to any sales, costs, expenses and payments under this

NILE, to examine the records of NILE and its Sublicensees during regular business hours before the Termination or expiration of this Agreement and for three (3) years thereafter, provided that such examination shall not take place more often
than once a year and shall be limited to a report on the accuracy of royalty statements and payments. If the audit report for any License Year discloses an underpayment discrepancy in royalties owed by NILE and royalties paid by NILE to MAYO that
exceeds [***] of total Net Sales or Sublicense Revenue made until the date of completion of the audit, NILE shall pay the reasonable expense of the audit and pay to MAYO the entire amount of the discrepancy plus interest within thirty (30) days
from the date upon which MAYO notified NILE of the discrepancy. Interest shall be computed at the rate which is the prime rate of Citibank N.A. (N.Y.) in effect at 9:00 a.m. on the day that MAYO notifies NILE of the discrepancy. Discrepancies in
royalty payments for a License Year identified by the audit report amounting to less than [***] shall be paid by the end of the License Quarter in which the audit was made.

liability and contractual liability, in an amount and for a time period sufficient to cover the liability assumed by NILE hereunder, such amount being at
least [***], provided that a lesser amount shall be acceptable to MAYO until such time as the Product enters into human clinical trials. In addition, such policy will name MAYO as an additional-named insured party.

Patents and Patent applications, at NILE’s expense, using counsel reasonably acceptable to MAYO, and shall keep MAYO informed of prosecution 
 8.02 Patent Term Extension. MAYO will have the sole right to decide on which Patent(s) to obtain a patent term extension; provided that MAYO will consider NILE’s input on the matter. NILE agrees to do all things which MAYO
determines are necessary to ensure the timely and complete filing and prosecution of any application for a patent term extension with the United States Patent and Trademark Office for any Product. NILE’s duties shall include, but not be limited

 Article 9 - Patent
Rights Enforcement 
 9.01 Third Party Litigation. In the event a third party institutes a suit against NILE for patent infringement involving a
Product, NILE will promptly inform MAYO and keep MAYO regularly informed of the proceedings. In the event the third party sues or joins MAYO, MAYO will have the right to control the defense of the suit. Each Party will bear its own costs of the suit
and any recovery will be shared equally by the Parties. 
 9.02 Infringement by Third Party. NILE and MAYO will promptly inform the other Party in
writing of any alleged infringement of any Patent and provide the other Party with available evidence of such infringement, and MAYO and NILE will have the right to institute an action for infringement of the Patents consistent with the following:

  

	(a)	If MAYO and NILE agree to institute suit jointly, then the suit will be brought in the names of both Parties. NILE will exercise control over such action, provided, however, that
MAYO may, if it so desires, be represented by counsel of its own selection, and at its own expense. 

  

	(b)	In the absence of an agreement to institute a suit jointly, MAYO may institute suit and, at its option, join NILE as a plaintiff. MAYO will bear the entire cost of such litigation,
including attorneys’ fees. NILE will cooperate reasonably with MAYO, except financially, in such litigation. MAYO will not settle or enter into a voluntary disposition of the action without NILE’s prior written consent.


  


	*	Confidential treatment has been requested for certain portions of this Exhibit. The confidential portions of this Exhibit have been omitted and filed separately with the
Securities and Exchange Commission. Such portions have been marked with “***” at the exact place where material has been omitted. 










	(c)	In the absence of an agreement to institute a suit jointly, and if MAYO determines not to institute a suit, as provided in paragraph (b) of this Section 9.02, then NILE
may institute suit and, at its option, join MAYO if MAYO is a necessary party to the litigation. NILE will bear the entire cost of such litigation, including attorneys’ fees. MAYO will cooperate reasonably with NILE, except financially, in such
litigation. NILE will not settle or enter into a voluntary disposition of the action without MAYO’s prior written consent. 

  

	(d)	Absent an agreement to the contrary, any costs under (a) above will be borne equally by the Parties and any recoveries will be shared in proportion to the economic damages
suffered by each Party. Otherwise, each Party will bear its own expenses and any recovery will be applied as follows: 

  

	 	(i)	first, to reimburse the Party bringing the action; 

  

	 	(ii)	second, to reimburse the expenses of the other Party in connection with such action; and 

  

	 	(iii)	third, [***] ([***]%) to MAYO and [***] ([***]%) to NILE. 

  

	(e)	If either Party institutes a suit under this Section 9.02 and then decides to abandon the suit, it will first provide timely written notice to the other Party of its intention
to abandon the suit, and the other Party, if it wishes, may continue prosecution of such suit, provided, however, that the sharing of expenses and of any recovery in such suit will be agreed-upon separately by the Parties. 


9.03 Patent Marking. To the extent commercially feasible and customary in the trade, NILE will mark all Products that are manufactured or sold under this
Agreement with the number of each issued patent within the Patents that cover such Product(s). Any such marking will be in conformance with the patent laws and other laws of the country of manufacture or sale. 
 Article 10 - General Provisions 
 10.01 Name Use. This Agreement does not convey any right to use any of the other Party’s names or
logos other than where required by law, rule or regulation. Neither Party may use publicly for publicity, promotion, or otherwise, any logo, name, trade name, service mark or trademark of the other Party or its Affiliates, or any simulation,
abbreviation or adaptation of the same, or the name of any of the other Party’s employee or agent without such other Party’s prior, written, express consent other than where required by law, rule or regulation. MAYO’s marks include,
but are not limited to, the terms “MAYO®” and “MAYO CLINIC®.” Any violation of this Section 10.01
constitutes a material breach of this Agreement. 
 10.02 Assignment. Nile may assign its rights and obligations under this Agreement to a third party
in conjunction with a Change of Control without Mayo’s prior written consent; provided that Nile shall remain responsible for the performance of its assignee, the assignee agrees to assume and be

bound by the provisions of this Agreement in writing and Nile promptly notifies Mayo of such assignment. Mayo’s written consent, which shall not be
unreasonably withheld, shall be required prior to any other assignment of Nile’s rights or obligations hereunder. Any other purported assignment is void. 
 10.03 Waiver. The failure of a Party to complain of any default by another Party or to enforce any of such Party’s rights, no matter how long such failure may continue, will not constitute a waiver of the Party’s rights
under this Agreement. The waiver by a Party of any breach of any provision of this Agreement shall not be construed as a waiver of any subsequent breach of the same or any other provision. No part of this Agreement may be waived except by the
further written agreement of the Parties. 
 10.04 Governing Law and Jurisdiction. This Agreement is made and performed in Minnesota. It is governed
by Minnesota law, but specifically not including Article 2 of the Uniform Commercial Code as enacted in Minnesota. This is not an Agreement for the sale of goods. In addition, no Minnesota conflicts-of-law or choice-of-laws provisions apply to this
Agreement. To the extent the substantive and procedural law of the United States would apply to this Agreement, it supersedes the application of Minnesota law. The exclusive fora for actions between the Parties in connection with this Agreement are
the State District Court sitting in Olmsted County, Minnesota, or the United States Court for the District of Minnesota. NILE agrees unconditionally that it is personally subject to the jurisdiction of such court.  
 10.05 Headings. The headings of articles and sections used in this document are for convenience of reference only, and shall not affect the meaning or
interpretation of this Agreement. 
 10.06 Notices. All notices and other business communications between the Parties related to this Agreement shall
