The proposals for the appointment of Ingrid Joerg and the re-appointment of John Ormerod to the Company’s Board of Directors for a period of three years following the Annual General Meeting, passed. The Company’s shareholders approved, on an advisory basis, “one year” as the frequency for holding an advisory (non-binding) vote on the compensation of the Company’s named executive officers. In light of such vote, the Company has determined to hold the advisory (non-binding) vote on the compensation of the Company’s named executive officers every year. The results for the remainder of the proposals are as set forth below. * For the purposes of French law, broker non-votes are treated as abstentions. Therefore, in terms of the voting results, broker non-votes, like other abstentions, were not counted as a vote cast on the applicable proposal. The voting results are as follows: 1.
