 15.4 No Strict Construction; Headings. This Agreement has been prepared jointly by the Parties and
shall not be strictly construed against either Party. Ambiguities, if any, in this Agreement shall not be construed against any Party, irrespective of which Party may be deemed to have authored the ambiguous provision. The headings of each Article
and Section in this Agreement have been inserted for convenience of reference only and are not intended to limit or expand on the meaning of the language contained in the particular Article or Section. Except where the context otherwise requires,
the use of any gender shall be applicable to all genders, and the word “or” is used in the inclusive sense (and/or). The term “including” as used herein means including, without limiting the generality of any description
preceding such term. 
 15.5 Assignment. Neither Party may assign this Agreement without the prior written consent of the other
Party, such consent not to be unreasonably withheld, except that either Party may assign this Agreement without the prior consent of the other Party: (a) to a Third Party successor to all or substantially all of its stock or assets relating to
the Product (an “Acquiror”), whether in connection with a merger, consolidation or sale of assets or other transaction; or (b) to its Affiliate. Any permitted assignment shall be binding on the successors of the assigning
Party. Any successor or assignee of rights and/or obligations permitted hereunder shall, in writing to the other Party, expressly assume performance of such rights and/or obligations. [* * *]. Any attempted or purported assignment in violation of
this Section 15.5 shall be null and void. 
 15.6 Performance by Affiliates. Each Party may discharge any obligations and
exercise any right hereunder through any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this
Agreement in connection with such performance. Any breach by a Party’s Affiliate of any of such Party’s obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed directly against such Party
without any obligation to first proceed against such Party’s Affiliate. 
 15.7 Further Actions. Each Party agrees to execute,
acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

 15.8 Severability. If any provision of this Agreement is found by a court of competent
jurisdiction to be unenforceable, then such provision shall be construed, to the extent feasible, so as to render the provision enforceable, and if no feasible interpretation would save such provision, it shall be severed from the remainder of this
Agreement. The remainder of this Agreement shall remain in full force and effect, unless the severed provision is essential and material to the rights or benefits received by either Party. In such event, the Parties shall negotiate, in good faith,
and substitute a valid and enforceable provision or agreement that most nearly implements the Parties’ intent in entering into this Agreement. 

15.9 No Waiver. No provision of this Agreement can be waived except by the express written consent of the Party waiving compliance.
Except as specifically provided for herein, the waiver from time to time by either Party of any of its rights or its failure to exercise any remedy shall not operate or be construed as a continuing waiver of same or of any other of such Party’s
rights or remedies provided in this Agreement. 
 15.10 Independent Contractors. For all purposes under this Agreement, ISU and
Catalyst are independent contractors with respect to each other, and shall not be deemed to be an employee, agent, partner or legal representative of the other Party. This Agreement does not grant any Party or its employees, consultants or agents
any authority (express or implied) to do any of the following without the prior express written consent of the other Party: create or assume any obligation; enter into any agreement; make any representation or warranty; serve or accept legal process
on behalf of the other Party; settle any claim by or against the other Party; or bind or otherwise render the other liable in any way. 

15.11 Governing Law. This Agreement shall be governed by the laws of the state of California, without regard to its choice of law
provisions that would require the application of the laws of a different jurisdiction. 
 15.12 Counterparts. This Agreement may be
executed in two (2) or more counterparts, each of which shall be deemed an original but all of which together shall constitute the same legal instrument.
