Each Ordinary Share was entitled to one vote per share for the election of Susan Moran, M.D., MSCE and one vote on each of proposals 3, 4 and 5. The holders of each Series A Preferred Share were entitled to 1,000 votes per share, voting as a separate class for the election of Jonathan Violin, Ph.D. and voting together with the holders of Ordinary Shares as a single class for the election of Susan Moran, M.D., MSCE, and were not entitled to vote on any other proposal.
