ARTICLE VII 

MISCELLANEOUS 

Section 7.1    Amendment and Waiver. This Agreement may be amended by the Company, the Founders and the

(solely as it relates to the Sponsor Group), Section 2.5 (solely as it relates to the Sponsor Group), Section 2.6(b), 

  
 13 












 
Section 2.8, 2.12 or 4.3 (solely as it relates to the Sponsor Group), Section 6.1, this Article VII or any definitions to the extent used therein
(including the definition of “Sponsor”, “Sponsor Director”, “Sponsor Group”, the final sentence of the definition of “Affiliate” and the proviso to the definition of “Necessary Action”) shall also
require the written consent of the Sponsor (unless, for the avoidance of doubt, if this Agreement is terminated with respect to the Sponsor pursuant to Section 6.1(b) above). 

Section 7.2    Severability. The Parties acknowledge that the rights and obligations provided for in this
Agreement are subject to the applicable provisions of applicable Laws and stock exchange regulations. In the event that any term, provision, covenant or restriction of this Agreement, or the application thereof, is held to be illegal, invalid or
unenforceable under any present or future applicable Law: (a) such provision will be fully severable; (b) this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part
hereof; (c) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance here from; and (d) in lieu of such illegal, invalid

 Section 7.3    Entire
Agreement. Except as otherwise expressly set forth herein, this Agreement and the documents referenced herein and therein embody the complete agreement and understanding among the Parties with respect to the subject matter hereof and
supersede and preempt any prior understandings, agreements or representations by or among the Parties, written or oral, which may have related to the subject matter hereof in any way. 

Section 7.4    Successors and Assigns. This Agreement shall be binding upon and shall inure to the
benefit of the parties hereto and their respective successors and permitted assigns and transferees. Neither this Agreement nor any rights, interests or obligations that may accrue to the Parties hereunder may be transferred or assigned by any Party
without the prior written consent of the other Parties hereto and any attempted assignment without such consent shall be null and void and of no effect; provided that each Founder, each Growth Investor and the Sponsor may assign any and all of their
respective rights under this Agreement, together with Transferring their respective Shares, to any member of its respective Group (each, a “Transferee”). A Founder, a Growth Investor or the Sponsor (as applicable) shall give written
notice to the Company of its transfer of rights under this Section 7.4 no later than five (5) Business Days after such Person enters into a binding agreement for such transfer of rights. Such notice shall state the
name and address of the Transferee and identify the amount of Shares transferred and the scope of rights being transferred under this Section 7.4. In connection with any such transfer, the term “Founders”,
“Growth Investors” or “Sponsor” as used in this Agreement shall, where appropriate to give effect to the assignment of rights and obligations hereunder to such Transferee, be deemed to refer to such Transferee. A Founder, a
Growth Investor or the Sponsor (as applicable) and any Transferee may exercise the rights under this Agreement in such priority, as among themselves, as they shall agree upon among themselves, and the Company shall observe any such agreement of
which it shall have notice as provided above. A Founder, a Growth Investor or the Sponsor (as applicable) shall cause Transferee to execute and deliver to the Company a joinder agreement in form and substance of Exhibit A attached hereto and agree
to be bound by the terms and conditions of this Agreement.

exchange for Shares held by any member of the Founders Group, the Crescera Group, the Inovabra Group or the Sponsor Group (as applicable), all of the rights of the Founders, the Growth Investors and the Sponsor set forth in this Agreement shall
continue in full force and effect and shall apply to the Person the equity securities of which are received by the Founders, the Growth Investors and the Sponsor pursuant to such transaction or series of related transactions. The Company agrees
that, without the consent of the Founders, it will not enter into any Contract which will have the effect set forth in the first clause of the preceding sentence, unless such Person agrees to be bound by the foregoing provision. 

Section 7.6    Counterparts. This Agreement may be executed in separate counterparts each of which shall
be an original and all of which taken together shall constitute one and the same agreement. 

Section 7.7    Remedies. The parties hereto agree and acknowledge that money damages may not be an
adequate remedy for any breach of the provisions of this Agreement and that a party hereto shall have the right to injunctive relief or specific performance, in addition to all of its rights and remedies at law or in equity, to enforce the
provisions of this Agreement. Nothing contained in this Agreement shall be construed to confer upon any Person who is not a signatory hereto any rights or benefits, as a third party beneficiary or otherwise.
