bear all Costs associated with or resulting from the development of a Joint Cell Line and/or Joint Product, from the conclusion of the Feasibility Work to before entering Phase I Clinical Trials, during which period the Primary Party and the Secondary Party shall split the Revenue generated from such Joint Cell Line and/or Joint Product in shares of 60% and 40%, respectively;

If the Parties cannot agree on the terms of such Statement of Work, then the Parties hereby agree to reasonably negotiate a separation agreement between the Parties with respect to such Project. For purposes of clarity, the exercise of a Party’s Option (or the decision not to exercise such Option) in accordance with the terms of this Article 4 with respect to a specific Project does not affect any rights of the Parties with respect to other Projects that are part of the Program, or with respect to the Program itself.

law (including releases that may be required to be filed with the SEC), that Party will notify the other Party as soon as practicable and give as much detail as possible in relation to the disclosure required. The Parties will then cooperate with respect to determining what information should actually be released.

11.2

Publications. During the term of this Agreement, each Party shall provide the other Party with an opportunity to review and comment upon any proposed abstracts, manuscripts or proposed presentations that relate to a Project at least sixty (60) days prior to their intended submission for publication and agrees, upon request, not to submit such an abstract or manuscript for publication until the Parties have reasonably agreed upon whether or not to file for patent protection for any material in such publication which the other Party believes to be patentable. Upon one Party’s reasonable request, the other Party shall delete from its abstracts, manuscripts or presentations any reference to such Party’s Intellectual Property Rights to the extent such Party’s Intellectual Property Rights contain trade secrets and/or submitted but not yet published patent filings of such Party.

11.3

12.2

Termination.

(a)

Dissolution or Insolvency Event. Either Party may terminate this Agreement effective immediately upon delivery of a Termination Notice if the other Party (i) is dissolved under applicable corporate law and there is no successor to such Party’s business or assets relating to this Agreement, or (ii) becomes subject to an Insolvency Event.

(b)

Default. If either Party believes the other is in default of any of its material obligations under this Agreement, including failing to comply with a Statement of Work, it may give notice of such default to the other Party, which Party shall have sixty (60) days in which to remedy such default. If such alleged default is not remedied in the time period set forth above, the Party alleging default may terminate this Agreement immediately upon delivery to the defaulting Party of a Termination Notice. The non-defaulting Party’s right to terminate this Agreement shall not be construed as an exclusive remedy.

12.3

Wind Down Procedures. In the event of termination of a Project, the Program, or this Agreement, as the case may be, pursuant to Section 12.1 or 12.2, the Project, Program, or Agreement shall be discontinued as of the Termination Date and the Parties shall in good faith commence the Wind Down Procedures promptly upon delivery of the Termination Notice. As part of such Wind Down Procedures, (i) SRNE shall return to CONKWEST all CONKWEST Existing Rights, excluding CONKWEST Cell Lines embodied in a Joint Cell Line, and (ii) CONKWEST shall return to SRNE all SRNE Existing Rights, excluding SRNE TTM-modified Joint Cell Lines. The Primary Party for the specific Joint Cell Lines and/or Joint Products that have been generated shall have sole discretion to either continue or discontinue the development of the specific Joint Cell Lines and Joint Products. No new Project, however, shall be initiated by either Party.

Further, the provisions of Section 2.3(b)(iii), 2.4, and this 12.4, and of Articles 1 (Definitions), 6 (Intellectual Property), 7 (Representations and Warranties), 8 (Disclaimer and Waiver), 9 (Confidentiality), 10 (Indemnification and Insurance), 11 (Publicity), and 13 (Miscellaneous) of this Agreement, together with any provisions required for the interpretation or enforcement of any of the foregoing, shall survive the termination or expiration of this Agreement. Termination of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of either Party prior to such termination.

13.1

Agency. Neither Party is, nor shall be deemed to be, an employee, agent, partner or legal representative of the other Party for any purpose. Neither Party shall have the right, power or authority to enter into any contracts in the name of, or on behalf of, the other Party, nor shall either Party have the right, power or authority to pledge the credit of the other Party in any way or hold itself out as having the authority to do so.

13.2

Assignment. Neither Party may assign this Agreement or any of its rights, duties, or obligations hereunder without the prior written consent of the other Party; provided, however, that either Party may assign this Agreement without the consent of the other

Party (a) to an affiliate of the assigning Party, or (b) to a Third Party in connection with a Strategic Transaction. Any purported assignment in violation of the foregoing shall be void. Any permitted assignee shall assume all obligations under this Agreement.

13.3

Further Actions.

13.4

Force Majeure. If any Party is impeded in fulfilling its undertakings in accordance with this Agreement by labor conflict, unforeseen acts of nature, including but not limited to flood, fire, storm etc., accident, war, mobilization or unforeseen military call-up of a large magnitude, requisition, confiscation, commandeering, legislative or judicial or regulatory action, riot, insurrection, sabotage, terrorism, explosion, general shortage of transport, goods or energy and faults or delays in deliveries from sub-contractors or suppliers caused by any circumstances referred to in this Section 13.4, the impediment shall be considered a Force Majeure and the Party shall be excused from liability for delays due to such reasons, provided always that it notifies the other Party without undue delay after such a circumstance has occurred and provides the other Party with an estimate of the length of time during which it is probable that it will be unable to comply with said obligation(s). Where applicable, the Parties agree to set in place without delay any means to enable them to prevent a rupture in the supply of any Product likely to have deleterious consequences for public health. In the event that the case of Force Majeure should last more than ninety (90) days, any Party shall have the option to suspend application of this Agreement, which will resume automatically upon termination of the Force Majeure.
