or own any rights to acquire (directly or indirectly) any equity securities of Acquiror or any equity securities convertible into,
or which can be exchanged for, equity securities of Acquiror.


 


(c)            No
Conflicts. The execution and delivery of this Sponsor Agreement by such Sponsor does not, and the performance by such Sponsor
of his, her or its obligations hereunder will not, (i) if such Sponsor is not an individual, conflict with or result in a
violation of the organizational documents of such Sponsor or (ii) require any consent or approval that has not been given
or other action that has not been taken by any Person (including under any Contract binding upon such Sponsor or such Sponsor’s
Acquiror Ordinary Shares or Acquiror Warrants), in each case, to the extent such consent, approval or other action would prevent,
enjoin or materially delay the performance by such Sponsor of its, his or her obligations under this Sponsor Agreement.

There are no Actions pending against such Sponsor, or to the knowledge of such Sponsor threatened against such Sponsor, before
(or, in the case of threatened Actions, that would be before) any arbitrator or any Governmental Authority, which in any manner

this Sponsor Agreement.
