ARTICLE 2

RESEARCH PROGRAMS

2.1 General. Subject to the terms and conditions of this Agreement, for each Collaboration Target, the Parties will collaborate on the certain preclinical development activities with the goal of identifying Binding Peptides to such Collaboration Target more fully described in this Article 2 (each research program, a “Research Program”). Each Research Program shall include [***]. Each Research Program will be conducted in accordance with the Research Plan and Research Budget for such Research Program. The initial Research Plan and corresponding Research Budget for the Research Program for Target 1 has been agreed to as of the Effective Date and is attached to this Agreement as Schedule 2.1. Each Research Plan and corresponding Research Budget may be amended from time to time by the Parties’ mutual written agreement. Except as agreed in writing by the Parties otherwise, there shall be no more than [***] Collaboration Targets (Target 1 or the Replacement Target for Target 1 on the one hand, and up to [***] Option Targets or the Replacement Targets for such Option Targets on the other hand) at any given time under this Agreement.

2.2 Research Costs. [***] shall be responsible for all Research Costs, whether incurred by [***] after the Effective Date in the Territory, in each case in accordance with the Research Plan and Research Budget. [***] shall reimburse [***] for Research Costs as set forth in Section 5.3. The Parties shall act in good faith and in a reasonable and timely manner to: (a) consider adjustments to the Research Costs based on the progress of the Research Program; and (b) enter into a Research Plan and Research Budget for any Option Targets.

15

2.3 Replacement of Target 1 or the Option Targets. With respect to Target 1 and each Option Target, if Nimble is unable to demonstrate feasibility of using the Nimble Technology against such Target within [***] following the Research Program Start Date for such Target (“Failure Period”), as reasonably determined by the JRC, then such Target shall cease to be a Collaboration Target, shall be deemed a “Failed Target” and the Research Plan and the Research Term for such Target shall terminate, in each case as of the date such determination and Rayze may in its sole discretion propose a Target to replace such Target in accordance with Section 2.4. By way of example, incompatibility of a Target [***] are bases for determining a Target to be a Failed Target. Either Party that wishes to declare that Target 1 or an Option Target is a Failed Target must notify the other Party in writing (which may be by email) during the Failure Period, and, by no later than [***] following receipt of such notice by the other Party, the JRC shall determine whether Target 1 or an Option Target is a Failed Target. For clarity, only the original Target 1 and each original Option Target may be replaced under this Agreement and in no event shall any Replacement Targets be replaced under this Agreement.

2.4 Process for Replacing Target 1 or the Option Targets.

2.4.1 Replacement Target Nomination. If Target 1 or an Option Target is determined to be a Failed Target pursuant to Section 2.3, Rayze may exercise its right to replace such Target by providing written notice to Nimble within [***] from such determination (“Target Nomination Notice”). Within [***] after receipt of the Target Nomination Notice, Nimble shall provide an updated and then current Not Available List to the Gatekeeper (which list shall be current and accurate as of the date of the Target Nomination Notice) and inform Rayze when the Gatekeeper has been updated with this information. Rayze shall then, within [***], provide written notice to the Gatekeeper of the identity of the Target that Rayze proposes to become the Replacement Target (including its UNIPROT number). Within [***] following the Gatekeeper’s receipt of such notice, the Gatekeeper shall verify whether or not such Target is on the Not Available List and notify the Parties in writing with respect thereto; provided that the Gatekeeper will only disclose the identity of such Target to Nimble if such Target is not on the Not Available List (the “Gatekeeper Replacement Target Notice”). If the Gatekeeper Replacement Target Notice indicates that a Target is on the Not Available List, then such Target shall not become the Replacement Target and Rayze shall have the right to propose an additional Target to replace Target 1 or an Option Target, as applicable, within [***] from Rayze’s receipt of the Gatekeeper Replacement Target Notice in accordance with this Section 2.4.1.

2.4.2 Replacement Target Selection. If the Gatekeeper Replacement Target Notice indicates that a Target is not on the Not Available List, then within [***] thereafter, the Parties shall negotiate in good faith and reach mutual agreement regarding an initial Research Plan and corresponding Research Budget for such Target. Such Research Plan shall be of comparable scope as the Research Plan the Parties agreed to for Target that is being replaced.

16

Upon the Parties reaching mutual written agreement regarding the initial Research Plan and corresponding Research Budget for such Target, (a) such Target shall be deemed the “Replacement Target” for Target 1 or the Option Target, as applicable and all terms applicable to the replaced Target shall now apply to such Replacement Target as if such Replacement Target is Target 1 or the Option Target, as applicable, except that none of the Replacement Target can be replaced again under this Agreement unless the Parties otherwise agree in writing; and (b) the replaced Target shall cease to be a Collaboration Target under this Agreement.

2.5 Option. Rayze shall have the right to nominate up to [***] additional Targets to become Option Targets in accordance with this Section 2.5 (the “Option”). Rayze may exercise the Option with respect to [***] Target(s) at any time during the Option Period.

2.5.1 Option Target Nomination. During the Option Period, Rayze may, in its sole discretion, provide written notice to Nimble that Rayze wishes to propose [***] Targets to become Option Targets (“Option Target Notice”). Within [***] after receipt of the Option Target Notice, Nimble shall provide an updated and then current Not Available List to the Gatekeeper (which list shall be current and accurate as of the date of the Option Target Notice) and inform Rayze when the Gatekeeper has been updated with this information. Rayze shall then, within [***], provide written notice to the Gatekeeper of the identity of each Target that Rayze proposes to become an Option Target (including its UNIPROT number). Within [***] following the Gatekeeper’s receipt of such notice, the Gatekeeper shall verify whether or not such Target is on the Not Available List and notify the Parties in writing with respect thereto; provided that the Gatekeeper will only disclose the identity of such Target to Nimble if such Target is not on the Not Available List (the “Gatekeeper Option Target Notice”). If the Gatekeeper Option Target Notice indicates that a Target is on the Not Available List, then such Target shall not be an Option Target and Rayze shall have the right to propose additional Target(s) during the Option Period in accordance with this Section 2.5.1 but in no event shall the number of Option Targets exceed [***].

2.5.2 Option Target Selection. If Gatekeeper notifies the Parties that a Target is not on the Not Available List, then within [***] thereafter, the Parties shall negotiate in good faith and reach mutual agreement regarding an initial Research Plan and corresponding Research Budget for such Target. Such Research Plan shall be of comparable scope as the Research Plan the Parties agreed to for Target 1. Upon the Parties reaching mutual written agreement regarding the initial Research Plan and corresponding Research Budget for such Target, such Target shall be deemed an “Option Target”. The Parties contemplate that Research Plans and Research Budgets for Option Targets shall be substantively similar to those for Target 1.

2.6 Not Available List. Nimble hereby represents that it has provided as of the Effective Date and will provide, within [***] of any Option Target Notice date, to its legal counsel, [***] (the “Gatekeeper”), a list of Targets with respect to which (a) Nimble has a dedicated internal development program ongoing (i.e., that has internally achieved the equivalent of Candidate Nomination or later with respect to such internal Target) or (b) Nimble has an ongoing collaboration with a Third Party or is engaged in negotiations or discussions with a Third Party for a collaboration or other strategic transaction (such list, the “Not Available List”). From time to time, Nimble may update the Not Available List to include any other Target meeting the criteria set forth in either clause (a) or clause (b) of the preceding sentence (or to remove any Target therefrom), which update shall in any event occur within [***] of receipt of an Option Target Notice.

5.17 Late Payments. Without limiting either Party’s remedies under this Agreement, any undisputed payments or portions thereof due hereunder that are not paid on the date such payments are due under this Agreement shall bear interest at a rate equal to [***] percentage points above the per-annum prime rate as published by The Wall Street Journal (U.S., Eastern Edition), or any successor thereto, at 12:01 a.m. on the first day of each Calendar Quarter in which such payments are overdue, calculated on the number of days such payment is delinquent. Where the late payment is caused by the Party that is owed the payment, including for reasons such as failure to communicate in a timely manner changes to bank details, or failure to respond to communications from the Party owing the payment regarding the interpretation or dispute of the terms of such payment, then no interest will be payable by the Party owing the payment.

5.18 Currency Conversion. All payments made under this ARTICLE 5 shall be made in Dollars. With respect to Net Sales of Program Products invoiced in a currency other than Dollars, such amounts and the royalty amounts payable under this Agreement shall be expressed in Dollars calculated using Rayze’s standard conversion method consistent with GAAP in a manner consistent with Rayze’s customary and usual conversion procedures used to prepare its audited financial statements for external reporting purposes.

5.19 Blocked Payments. In the event that, by reason of Applicable Laws in any country, it becomes impossible or illegal for a Party or its Affiliate, or Licensee to transfer, or have transferred on its behalf, payments to the other Party, such Party shall promptly notify the other Party of the conditions preventing such transfer and such payments shall be deposited in local currency in the relevant country to the credit of the other Party in a recognized banking institution designated by the other Party or, if none is designated by the other Party within a period of [***], in a recognized banking institution selected by such Party or its Affiliate, or Licensee, as the case may be, and identified in a notice given to the other Party.

Upon expiration of such [***], Rayze will be free to proceed with the publication or presentation. If Nimble reasonably requests modifications to the publication or presentation to prevent disclosure of Nimble Confidential Information, Rayze shall edit such publication to prevent the disclosure of such information prior to submission of the publication or presentation.

7.5.2 Once a publication or presentation has met the requirements of Section 7.5.1, Rayze may use the information contained in the publication or presentation without seeking further review by Nimble.

7.5.3 Rayze will ascribe authorship of any proposed publication using accepted standards used in peer-reviewed, academic journals at the time of the proposed publication.

7.5.4 Each publication made in accordance with this Section 7.5 shall not be a breach of the confidentiality provisions contained in Section 7.1.

No waiver by either Party of any condition or term in any one or more instances shall be construed as a continuing waiver or subsequent waiver of such condition or term or of another condition or term.

14.7 Severability. If any provision hereof should be held invalid, illegal or unenforceable in any jurisdiction, the Parties shall negotiate in good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties and all other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intentions of the Parties hereto as nearly as may be possible. Such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of such provision in any other jurisdiction, unless the invalid, illegal or unenforceable provisions are of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without such invalid provisions.

14.8 Entire Agreement. This Agreement, together with (a) the Schedules attached hereto and (b) each Research Plan as may be agreed by the Parties during the Option Term in accordance with Article 2, constitutes the entire agreement between the Parties with respect to the subject matter hereof and thereof. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or therein. This Agreement supersedes all prior agreements and understandings between the Parties with respect to the subject matter hereof, including the CDA, and all information exchanged between the Parties under the CDA shall be considered Confidential Information exchanged hereunder upon the Effective Date. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties hereto unless reduced to writing and signed by the respective authorized officers of both Parties.

14.9 Independent Contractors. Nothing herein shall be construed to create a partnership, or any relationship of employer and employee, agent and principal, or joint venture between the Parties. Each Party is an independent contractor. Neither Party shall assume, either directly or indirectly, any liability of or for the other Party. Neither Party shall have the authority to bind or obligate the other Party, and neither Party shall represent that it has such authority. Neither Party shall report the transactions and undertakings contemplated by this Agreement as a partnership for United States federal income tax purposes unless required pursuant to a “final determination” as defined in Section 1313 of the United States Internal Revenue Code.

14.10 Headings. Headings used herein are for convenience only and shall not in any way affect the construction of or be taken into consideration in interpreting this Agreement.

14.11 Further Actions. Each Party shall execute, acknowledge and deliver such further instruments, and do all such other acts, as may be reasonably necessary or appropriate in order to carry out the expressly stated purposes and the clear intent of this Agreement.

The Parties understand and agree that the Schedules hereto are not intended to be the final and complete embodiment of any terms or conditions of this Agreement, and are to be updated from time to time during the Term, as appropriate and in accordance with the provisions of this Agreement.

14.13 Counterparts. This Agreement may be executed and delivered (including by PDF or any other electronically transmitted signatures) in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

FIRST AMENDMENT TO RESEARCH COLLABORATION AND LICENSE AGREEMENT

This First Amendment to Research Collaboration and License Agreement (this “Amendment”) is entered into effective as of September 3, 2021 by and between and RayzeBio, Inc., a Delaware corporation having its principal place of business at 9880 Campus Point Dr., Suite 410, San Diego, CA 92121 (“Rayze”), and Nimble Therapeutics, Inc., a Delaware corporation having its principal place of business at 603 Science Dr., Madison, Wisconsin 53711 (“Nimble”). Rayze and Nimble are sometimes referred to individually as a “Party” and collectively as the “Parties.”

WHEREAS, the Parties wish to amend that certain Research Collaboration and License Agreement (the “Agreement”) entered into between the Parties effective as of February 8^th, 2021, subject to the terms and conditions herein.

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration the sufficiency of which is hereby acknowledged, the Parties agree as follows.

1.78 “Option Period” means the period commencing on the Effective Date and ending on the earlier of (a) [***] following the completion of Stage 2 for Target 1 or the Replacement Target, as applicable (as defined the Research Plan for Target 1 or the Replacement Target, as applicable), and (b) [***] following the Effective Date.

2.3 Replacement of Target 1 or the Option Targets. With respect to Target 1 and each Option Target, if Nimble is unable to demonstrate feasibility of using the Nimble Technology against such Target within [***] following the Research Program Start Date for such Target (“Failure Period”), as reasonably determined by the JRC, then such Target shall cease to be a Collaboration Target, shall be deemed a “Failed Target” and the Research Plan and the Research Term for such Target shall terminate, in each case as of the date such determination and Rayze may in its sole discretion propose a Target to replace such Target in accordance with Section 2.4. By way of example, incompatibility of a Target with the Nimble Technology resulting in the absence of [***] are bases for determining a Target to be a Failed Target. Either Party that wishes to declare that Target 1 or an Option Target is a Failed Target must notify the other Party in writing

(which may be by email) during the Failure Period, and, by no later than [***] following receipt of such notice by the other Party, the JRC shall determine whether Target 1 or an Option Target is a Failed Target. For clarity, only the original Target 1 and each original Option Target may be replaced under this Agreement and in no event shall any Replacement Targets be replaced under this Agreement.

IN WITNESS WHEREOF, the parties have executed this Agreement by their duly authorized representatives as of the Effective Date.
