(c)            No Conflicts. The execution and delivery of this Agreement by such Company Stockholder does not, and the performance by such Company Stockholder of his, her or its obligations hereunder will not, (i) if such Company Stockholder is not an individual, conflict with or result in a violation of the organizational documents of such Company Stockholder 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 Company Stockholder or such Company Stockholder’s Subject Shares), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Company Stockholder of its, his or her obligations under this Agreement.
