 Notes:

*SES respects “closed periods” around financial results announcements

During the closed periods, Board members and SES staff, including staff of affiliated companies, as well as the persons closely associated with them are not allowed to buy or sell any FDRs, or shares issued by SES, irrespective of whether they have inside information (i.e information which is not public but which if it became public was likely to have a significant impact on the price of SES shares) or not. They are not allowed to convert any stock options, or exercise any "STARs“ (Stock Appreciation Rights) during these periods either.
