employment is terminated other than for cause, as defined above, or (ii) there is a material reduction in salary, (for this purpose, 15% will be deemed a material reduction), or a material
reduction in your responsibility and as a result you choose to resign, you will be paid the base compensation and benefits for a further 12 months from the time of such reduction and your share
option (s) or restricted stock will vest in full. In addition, should there be a change in control prior to the full vesting of your share grant(s) or restricted stock, following which change
