3.02 First Right of Negotiation to Acquire Future MAYO Patents and New Improvements.

(a) With respect to any Future Patents and any improvements related to CD-NP and CU-NP developed after (i) the expiration of the […***…] commencing on the Original CD-NP Effective Date with respect to CD-NP, and (ii) the expiration of the […***…] commencing on the Original CU-NP Effective Date with respect to CU-NP (“New Improvements”), NILE shall have the exclusive right of first negotiation for, at NILE’s option, the exclusive or non-exclusive rights to such Future Patents owned (solely or jointly) by or assigned to MAYO and any New Improvements owned (solely or jointly) by or assigned to MAYO, not falling within the definition of MAYO Patents or Improvements hereunder. Such exclusive first right of negotiation shall be effective as of 1 June 2016, or as of such date when NILE shall have paid to MAYO all Unpaid Fees. However, prior to the date that such right of first negotiation shall be effective, upon disclosure to Mayo Clinic Ventures of any Future Patents or New Improvements, MAYO shall give NILE written notification thereof and NILE shall have the right to pay all Unpaid Fees at that time, which payment shall initiate the period for the exclusive first right of negotiation. Such notification shall be treated as MAYO’s Confidential Information.

(b) As of 1 June 2016, or as of such date when NILE shall have paid to MAYO all Unpaid Fees, NILE shall have […***…] days thereafter in which to negotiate to acquire the exclusive or non-exclusive rights to any such Future Patents and/or New Improvements, such negotiations to be concluded within […***…], unless extended by written agreement of the Parties.

*Confidential Treatment Requested

[…***…] negotiation period, MAYO shall have no further obligation to NILE and can freely disclose, dispose of and exploit such Future Patents and/or New Improvements.

3.03 Reservation of Rights.

3.05 All Other Rights Reserved. Except as granted in Section 3.01 and 3.02, 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 Amended Agreement be construed as an assignment by MAYO to NILE of any intellectual property rights.

3.06 Confidentiality. During the Term, and for a period of […***…], each Party hereto agrees to keep confidential by not disclosing to any third party any Confidential Information disclosed by one Party (the “Disclosing Party”) to the other (the “Receiving Party”).

Once a Product becomes commercially available, to the extent permitted by law, NILE will provide Products to MAYO and their Affiliates solely for it and their use for internal clinical, 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.

3.08 Sublicensee Actions. NILE may enter into sublicensing agreements under the MAYO Patents and Future Patents, Know-How and New Improvements, if applicable. NILE shall not receive, or agree to receive, anything of value in lieu of cash or equity as consideration from a third party under a sublicense agreement without the prior written consent of MAYO. For purposes of clarity, Sublicense consideration shall not include (a) any amounts paid to NILE specifically designated for co-development purposes, pre-clinical and clinical research and development of the Product, (b) any amounts paid to NILE for product manufacturing, or (c) purchases of debt or equity securities of NILE.

NILE shall be and remain responsible for enforcing such sublicensees’ obligations under the respective sublicense agreement, and any action by a sublicensee that would, if conducted by NILE, be a breach of this Amended Agreement, shall be deemed a breach of this Amended Agreement by NILE; provided, however, that NILE shall have sixty (60) days after notice from MAYO of any such breach in which to cure the same. NILE shall 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 3.08 shall be void.

10.01 Name Use. This Amended 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 Amended Agreement.

10.02 Assignment. NILE may assign its rights and obligations under this Amended Agreement to (a) an Affiliate or (b) a third party in conjunction with an acquisition or Change of Control; in each case 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 Amended Agreement in writing and NILE promptly notifies MAYO of such assignment. MAYO's written consent, which shall not be unreasonably withheld, conditioned or delayed, 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 Amended Agreement. The waiver by a Party of any breach of any provision of this Amended Agreement shall not be construed as a waiver of any subsequent breach of the same or any other provision. No part of this Amended Agreement may be waived except by the further written agreement of the Parties.

10.04 Governing Law and Jurisdiction. This Agreement shall be governed by and construed under the laws of the State of Delaware, without regard to its conflict of law provisions.

10.13 Construction. The Parties agree to all of the terms of this Amended Agreement and have had the opportunity to review it thoroughly prior to its execution. That one Party or another may have drafted all or a part of this Amended Agreement will not cause this Amended Agreement to be read more strictly against the drafting Party. This Amended Agreement, and any changes to it, will be interpreted on the basis that the Parties contributed equally to the drafting of all of its parts.

10.14 Nondisclosure. Except as permitted herein, neither Party will disclose any of the terms of this Amended Agreement without the express, prior, written consent of the other Party, or unless required by law or a regulatory authority.
