Exhibit 10.26

COST ALLOCATION AGREEMENT

This Cost Allocation Agreement (this “Agreement”), entered into on January 29, 2020, but made effective as of October 1, 2019 (the “Effective Date”), documents the mutual understanding with respect to certain joint clinical research activities that NantKwest, Inc., a Delaware corporation (“NantKwest”) and ImmunityBio, Inc., a Delaware corporation, and its subsidiaries (“IB”) intend to conduct as development partners.  In consideration of the mutual promises and covenants set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

1.Joint Studies.  The parties may from time to time agree to co-sponsor and conduct certain combination clinical studies (each a “Joint Study”) pursuant to clinical trial protocols wherein at least one investigational agent is a proprietary therapeutic drug candidate owned or controlled by NantKwest (each, an “NK Study Drug”) and at least one other investigational agent is a proprietary therapeutic drug candidate owned or controlled by IB (each, an “IB Study Drug”).   Each NK Study Drug and IB Study Drug may be referred to individually or collectively herein as a “Study Drug” or “Study Drugs.”

2.Work Orders.  Prior to initiating any activities for a Joint Study, the parties shall agree in writing in a separate work order (each, a “Work Order”) describing, amongst other things: (i) their respective development and management responsibilities (the “Development Activities”); (ii) the respective allocation of Joint Study costs and expenses in accordance with Section 3 below; (iii) regulatory responsibilities; and (iv) any other matters relating to the Joint Study.  

3.Joint Study Costs and Payment Terms.  

a.The parties agree to allocate the total costs (the “Total Cost”) associated with each Joint Study (the “Cost Allocation”) as set forth in the applicable Work Order.  Unless expressly agreed otherwise in a Work Order, the following costs shall be included when calculating the Total Cost to be allocated between the parties in connection with each Joint Study:  (i) all costs and expenses incurred by a party in connection with the Development Activities of the specific Joint Study including personnel related costs; (ii) all costs and expenses incurred by a party pursuant to third party and related party contracts relating to the Joint Study; (iii) all costs associated with regulatory matters associated with the Joint Study; and (iv) any other fees, charges and expenses incurred in connection with the Joint Study.  Any costs, expenses, and fees incurred by each party in connection with each Joint Study that make up the Total Cost shall be charged at cost, without mark-up or profit, but including reasonable allocations of employee benefits and other direct and fairly allocated indirect costs that relate to the employees or consultants providing the applicable services.

b.Notwithstanding anything else in this Agreement to the contrary, each party shall bear its own costs and expenses incurred in connection with the development, manufacturing, supply, delivery, and pre-patient administration dosing mechnanics of its respective Study Drugs and such costs shall not be included in the Total Cost.

1

c.NantKwest and IB will jointly develop a mutually agreeable budget for each Joint Study (the “Budget”), which Budget may be updated from time to time upon mutual consent.  Neither party may, without the prior written approval of the other party, incur any expenses in connection with a Joint Study except as expressly contemplated in the applicable Budget.  For each Joint Study, the parties will also jointly prepare a quarterly, non-binding forecast (each, a “Forecast”) in order to estimate the anticipated Joint Study expenses to be incurred in each calendar quarter.  Notwithstanding the foregoing or anything else in this Agreement to the contrary, a variance between the actual amounts incurred and the amounts contemplated in each then-current Budget or Forecast shall neither excuse nor waive a party’s obligations with respect to the sharing of Joint Study expenses in accordance with the cost allocation set forth in the applicable Work Order.  

d.Within five (5) days of the end of each calendar month, each party shall provide the other with a good faith estimate of its itemized costs (internal and external) in the previous month relating to the applicable Joint Study, and a final, itemized report of the previous month’s costs will be delivered to the other party within ten (10) days of the end of each month.  The reports will be used to calculate the amount to be reimbursed by one party to the other by taking into account the over- or under-payment of each party relative to its share based on the Cost Allocation.  When calculating the amount owed, one party may offset the amounts owed by the other party and pay the net amount to the other party.  Payments of all undisputed amounts invoiced shall be payable within thirty (30) days of invoice receipt.  

4.Regulatory Responsibilities.  Each Work Order shall set forth the respective roles and responsibilities of the parties with respect to regulatory submissions and related activities for the applicable Joint Study, including without limitation the responsibility for preparing and filing the Investigational New Drug application (the “IND”) filed with the United States Food and Drug Administration (the “FDA”).  Such designated party shall be responsible for preparing, filing and maintaining all regulatory filings, including submissions and correspondence, and compliance with all requirements for the conduct of the applicable Joint Study.  

a.Each party shall provide the other with a reasonable opportunity to review and comment upon all regulatory submissions no later than 15 days prior to the anticipated date of such submissions and will in good faith incorporate the comments from the other party.  

b.Each party hereby grants to the other party a non-exclusive, non-transferable (except in connection with a permitted assignment, sublicense or subcontract) “right of reference” (as defined in US FDA 21 CFR 314.3(b)), or similar “right of reference” as defined in applicable regulations in the relevant jurisdiction to its regulatory submissions, solely as necessary for the other party to prepare, submit and maintain regulatory submissions for its respective Study Drug(s).  Further, each party shall provide to the other a cross-reference letter or similar communication to the applicable regulatory authority to effectuate such “right of reference” on a need-to-know basis with respect to the confidential part of the Drug Master Files of both parties. Where a “right of reference” is not possible, the parties will promptly discuss in good faith on how to make the required documentation available for regulatory submissions of Study Drug(s). Neither Party shall have the right to access the other party’s Chemistry Manufacturing and Controls (CMC) data with respect to its Study Drug(s) without the express written consent of the other Party, except in the following circumstances: (i) to the extent required by applicable law or regulation; (ii) in the event the Parties elect to file joint regulatory submissions for one or more Joint Studies; or (iii) as expressly authorized in writing by the other Party.

5.Joint Study Contracts.  For each Joint Study, the parties will designate either NantKwest or IB as the contracting party to enter into agreements with third or related parties, including without limitation, clinical trial agreements, relating to the conduct and management of the applicable Joint Study; provided, that the contracting party may not enter into any material agreement (including without limitation any clinical trial agreement) relating to a Joint Study without the express prior written consent of the other party and, provided further, that the other party shall also obtain the express prior written consent of the contracting party prior to entering into any agreements with third or related parties in connection with a Joint Study.  Concurrently with the execution of each clinical trial agreement (CTA) relating to a Joint Study, the parties will execute a separate side letter to document their respective rights and obligations pursuant to such CTA.  Further, to the extent of any other material agreements that may be required in connection with a particular Joint Study, the non-contracting party shall have the right to review and comment on the terms of such material agreement prior to execution.  

6.  Joint Decision-Making.  

a.Steering Committee.  Within 30 days after the effective date of each Work Order, the parties shall establish a steering committee (the “Steering Committee”) to discuss Development Activity objectives for the applicable Joint Study and review the data and to monitor and to make certain decisions regarding such Joint Study. The Steering Committee will have reviewing, monitoring and approving responsibilities for the Joint Study and will attempt to facilitate the resolution of any disputes between the parties, as described in Section 6(c) below.  The Steering Committee will also provide a forum for sharing advice, progress and results relating to such activities.  Each party, through its representatives on the Steering Committee, will be permitted to provide advice and commentary with respect to the Joint Study.  Each party will take such advice and commentary into good faith consideration when performing its duties hereunder.  More specifically, the Steering Committee will:  

For clarity, the Steering Committee will not have any power to amend, modify or waive the terms of this Agreement or any Work Order unless agreed to by both parties in writing.
