Article 2
CONDUCT OF RESEARCH PROGRAM

2.1 Research Program.

(a) Target Selection. The Parties intend to initiate one or more Research Programs, each focused on a particular Target (each, a “Selected Target”). No more than one (1) Selected Target will be included in any Research Program, unless the Parties otherwise agree in writing (e.g., in the case of a Research Program seeking to develop a [***]). As of the Effective Date, the Parties have agreed to the Selected Targets listed on Exhibit A. Additional Targets may be added to the Selected Targets by mutual written agreement of the Parties, it being understood that each Party may accept or reject a new Selected Target in its sole discretion and no Party shall be obligated under this Agreement to agree to any further Selected Targets. The Parties acknowledge that, prior to any agreement with respect to a Selected Target and a Research Plan, it is intended that the Parties may initiate, from time-to-time, “proof-of-concept” studies [***] at no up-front Research Initiation Fee to Oruka; provided, that the costs of any such “proof-of-concept” studies may be recaptured by Paragon within the specified Research Plan and associated fees, in each case, as agreed by the Parties.

(b) Research Plan. No later than [***] after the Effective Date (or in the case of any Selected Target added after the Effective Date, no later than [***] days after the Parties’ written agreement on such additional Selected Target), the Parties will agree on a research plan, to the extent a research plan has not been previously agreed upon, for the applicable Selected Target that will include design, modeling, synthesis, evaluation, and other mutually agreed activities (“Research Plan”). For clarity, if at the end of such [***] period (or any extension thereof mutually agreed in writing) (i) the Parties have not agreed on a Research Plan, or (ii) Oruka has not paid Paragon the Research Initiation Fee, the applicable Target shall cease to be a Selected Target and Paragon shall have no obligations with respect thereto. Once the Parties agree on a Research Plan and Oruka pays the Research Initiation Fee for a Research Program, Paragon and Paruka shall conduct research under such Research Program during the applicable Research Term in an effort to (1) produce Project Antibodies against the applicable Selected Target for further Development, Manufacture and Commercialization (“Antibody Production Activities”), and (2) perform such other Development and Manufacturing activities with respect to the Project Antibodies as set forth in the Research Plan (which other activities, for clarity, may be performed following Xxxxx’s exercise of the Option or execution of a License Agreement). The Parties may amend the Research Plan upon mutual written agreement. Paragon and Paruka will use [***] to conduct and complete the activities set forth in such Research Plan on the timelines set forth in such Research Plan and in compliance with the Budget.

(c) Deliverables; Project Antibody Samples.

(i) Following completion of the Antibody Production Activities set forth in the Research Plan for a Research Program, Paragon and Xxxxxx will deliver to Oruka a data package that includes Sequence Information for all then-existing Project Antibodies and Results (the “Deliverables”). Additionally, upon request by Xxxxx, and at [***] cost and expense, Paragon and Paruka shall provide to Oruka samples of proteins corresponding to such Project Antibodies that have been expressed in accordance with the Research Plan (“Project Antibody Samples”) to enable Oruka to evaluate the Option. Following completion of a Research Program, Paragon shall deliver to Oruka the Final Deliverable for such Research Program, if any.

(ii) During the Option Period with respect to each Research Program, Xxxxx will review the Deliverables and Project Antibody Samples for such Research Program to determine whether [***] Project Antibody meets the Project Antibody Selection Criteria. If Oruka determines that [***] Project Antibody meets the Project Antibody Selection Criteria, then Oruka shall so notify Paragon in writing prior to the end of the Option Period.

Paragon shall have the right to adjust the Monthly Rate on an annual basis to account for inflation and other increases in costs by providing written notice thereof to Oruka at least [***] days prior to the commencement of each [***].

(b) On a quarterly basis, Xxxxx will advance to Paragon any Development Costs contemplated in the Research Budget, including [***], and any [***] reasonably expected to be incurred by Paragon in the performance of the Research Program during the upcoming [***] in accordance with the Research Plan and Research Budget (less any pre-payments for Third Party Costs from earlier [***] that Paragon reasonably anticipates will be carried over to such upcoming [***]) (the “Cost Advance”). On a quarterly basis, Xxxxxxx will deliver an invoice to Oruka for the Cost Advance, and Oruka will pay the Cost Advance within [***] after receipt of Paragon’s invoice.

(c) Within [***] after the end of each Calendar Year, Paragon will calculate and provide to Oruka a written reconciliation of its actually-incurred Third Party Costs (incurred in a manner consistent with the Budget) for the prior Calendar Year (“Actual Annual Costs”) against that portion of the Cost Advance for such Third Party Costs for that Calendar Year, including reasonable documentation of such Actual Annual Costs. The form of such reconciliation shall be subject to JDC review and approval. If the amounts paid for anticipated Third Party Costs in the Cost Advance exceeds the Actual Annual Costs, then Paragon will credit such excess payment against Development Costs contemplated in the Budget and reasonably expected to be incurred by Paragon in the performance of the Research Program during any upcoming Calendar Year and Oruka will deduct such amount from its next quarterly Cost Advance. If the Cost Advance is less than the Actual Annual Costs, then Paragon will invoice Oruka for the difference and Oruka will pay such amount together with its next quarterly Cost Advance. If no further amounts will be owed to Paragon hereunder, Xxxxxxx will refund such amount. For clarity, the above reconciliation will not apply to Annual Development Fees.

(d) Notwithstanding Sections ‎5.2(a), ‎5.2(b) and ‎5.2(c) to the contrary, the Parties acknowledge that Paragon has incurred (i) [***] in Development Costs through December 31, 2023, and (ii) certain additional Development Costs between January 1, 2024 and the Effective Date, as a result of work performed by Paragon at risk on the Research Program for IL-17A/F (the costs described in (i) and (ii), the “IL-17A/F Pre-Effective Date Development Costs”). Oruka shall reimburse Paragon for the IL-17A/F Pre-Effective Date Development Costs within [***] after Xxxxx’s receipt of a written invoice that details the IL-17A/F Pre-Effective Date Development Costs.

5.3 Financial Records. Paragon shall keep complete and accurate books of account and records in sufficient detail to enable the Development Costs payable under this Agreement to be determined. Such books and records shall be kept at the principal place of business of Paragon, for at least [***] following the end of the [***] to which such books and records pertain and Oruka shall be entitled to inspect such books and records at Paragon’s offices upon Xxxxx’s reasonable request.

5.4 Manner and Method of Payment. All cash payment amounts hereunder are expressed in U.S. dollars (USD) unless otherwise specified. Each payment shall be made by electronic funds transfer in immediately available funds to a bank and account designated in writing by Paragon, unless otherwise specified in writing by Paragon.

5.5 Tax. Each Party shall be responsible for paying its own respective taxes in connection with any activities that it performs and any payments that it receives under this Agreement. The Parties will commit [***] to provide each other with any tax forms that may be reasonably necessary in order for any Party to not pay or withhold tax or to pay or withhold tax at a reduced rate under an applicable income tax treaty.

5.6 Late Payments. In the event that any cash payment due for any undisputed amount under this Agreement is not made when due, then the cash payment shall accrue interest from the date due at a per annum rate equal to [***] above the then-current per annum prime rate reported by the Wall Street Journal (U.S., Western Edition) or, if lower, the maximum legal annual interest rate.

5.7 Equity Grants. Except as expressly agreed otherwise by the Parties in writing, upon completion of each of the Calendar Years ending December 31, 2024 and December 31, 2025, Oruka will grant to Paruka a warrant to purchase a number of Shares equal to 1.00% of the outstanding Shares as of the date of the grant, on a fully-diluted basis (assuming the exercise or conversion of any convertible non-voting preferred stock, stock options, pre-funded warrants or similar instruments), with an exercise price equal to the fair market value of the underlying Shares on the date of the grant as determined by the board of directors of Oruka (each grant, an “Equity Grant”); provided, that if Oruka undergoes a reverse merger transaction the rights and obligations of this Section ‎5.7 shall continue and Paruka shall be entitled to warrants from the ultimate public company parent to purchase a number of shares of such parent equal to 1.00% of the outstanding shares of the parent as of the date of the grant, on a fully-diluted basis (assuming the exercise or conversion of any convertible non-voting preferred stock, stock options, pre-funded warrants or similar instruments), as applicable. Such warrants will be exercisable for a period of ten (10) years following the date of the grant. Each Equity Grant shall be effected on the last Business Day of each applicable Calendar Year and the corresponding grant date shall be such date. If the Term ends prior to the end of a Calendar Year, the Equity Grant for such Calendar Year shall be pro-rated for such Calendar Year and such Equity Grant shall be effected within five (5) Business Days of the end of the Term.

This Agreement, together with all Exhibits attached hereto, constitutes the final, complete, and exclusive agreement of the Parties with respect to the subject matter hereof and supersedes all prior and contemporaneous understandings and agreements, relating to its subject matter. This Agreement (including its Exhibits) may not be changed, modified, amended, or supplemented except by a written instrument signed by all Parties.

11.4 Non-Waiver. The failure of a Party to insist upon strict performance of any provision of this Agreement or to exercise any right arising out of this Agreement shall neither impair that provision or right nor constitute a waiver of that provision or right, in whole or in part, in that instance or in any other instance. Any waiver by a Party of a particular provision or right shall be in writing, shall be as to a particular matter and, if applicable, for a particular period of time and shall be signed by such Party.

11.5 Severability. Should one or more of the provisions of this Agreement become void or unenforceable as a matter of Applicable Law, then this Agreement shall be construed as if such provision were not contained herein and the remainder of this Agreement shall be in full force and effect, and the Parties will use their best efforts to substitute for the invalid or unenforceable provision a valid and enforceable provision which conforms as nearly as possible with the original intent of the Parties.

11.6 Assignment. Neither this Agreement nor any rights or obligations hereunder may be assigned by any Party without the prior written consent of the other Parties (which consent shall not be unreasonably withheld); provided, however, that any Party may assign this Agreement and its rights and obligations hereunder without the other Parties’ consent to its successor to all or substantially all of the business of such Party to which this Agreement relates, whether by merger, sale of stock, sale of assets or otherwise.

In the event of the occurrence of any Dispute, the Parties will follow the following procedures in an attempt to resolve the dispute or disagreement:

(a) The Party claiming that such a Dispute exists will give notice in writing (a “Notice of Dispute”) to the other Parties of the nature of the Dispute.

(b) The Dispute will be referred to the then Chief Executive Officer or Chief Operating Officer of Paragon and the then Chief Executive Officer or President of Xxxxx who will meet no later than [***] days following the initial receipt of the Notice of Dispute and use reasonable endeavors to resolve the Dispute.

(c) If, within [***] days of initial receipt of the Notice of Dispute, the Dispute has not been resolved, or if, for any reason, the meeting described in Section ‎11.7‎(b) hereof has not been held within [***] days of initial receipt of the Notice of Dispute, then the Parties agree that such Dispute will be finally resolved through binding arbitration to be administered by JAMS pursuant to its Comprehensive Arbitration Rules and Procedures and in accordance with the Expedited Procedures in those Rules, as specifically modified by the provisions of this Section ‎11.7‎(c). The arbitration will be conducted by a panel of three arbitrators.

All three arbitrators must be independent Third Parties having at least [***] years of dispute resolution experience (which may include judicial experience) or legal or business experience in the biotech or pharmaceutical industry. If any Party fails to nominate its arbitrator, or if the arbitrators selected by the Parties cannot agree on a person to be named as chairman within such [***]-day period, JAMS will make the necessary appointments for such arbitrator(s) or the chairman. Once appointed by a Party, such Party will have no ex parte communication with its appointed arbitrator. The place of arbitration will be in Boston, Massachusetts or such other venue as the Parties may mutually agree. The arbitration proceedings and all communications with respect thereto will be in English. Any written evidence originally in another language will be submitted in English translation accompanied by the original or a true copy thereof. The arbitrators have the power to decide all matters in Dispute, including any questions of whether or not such matters are subject to arbitration hereunder. The arbitration will be governed by the Federal Arbitration Act, 9 U.S.C. §§1 et seq., and judgment upon the award rendered by the arbitrators may be entered in any court having competent jurisdiction thereof. The existence, content and results of any arbitration proceedings pursuant to this Section ‎11.7 will be deemed the Confidential Information of all Parties.

(d) Notwithstanding any provision of this Agreement to the contrary, any Party may immediately initiate litigation in any court of competent jurisdiction seeking any remedy at law or in equity, including the issuance of a preliminary, temporary or permanent injunction, to preserve or enforce its rights under this Agreement.

(e) The Parties agree that any disputes relating to ‎Article 7 (Confidentiality) hereof or disputes relating to the determination of the validity, scope, infringement, enforceability, inventorship or ownership of the Parties’ respective Intellectual Property Rights shall be subject to the exclusive jurisdiction of the state and federal courts in New York, New York and each Party hereby submits to such jurisdiction.

11.8 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts without reference to conflicts of laws principles.

11.9 Notices. Any notice to be given under this Agreement must be in writing and delivered either in person, by internationally recognized express courier, by email, or by facsimile, to the Party to be notified at its address(es) given below, or at any address such Party has previously designated by prior written notice to the other.
