15% is what I came up with to get the $1 million merger consideration for #2. As I read it, those shares wanting appraisal rights can not exceed $1 million dollars of consideration. Or .05 X 15% of the shares.
I believe you are mistaken. No where in Delaware code 262 which this falls under does it say that a dissenter needs 1% of the shares. Any shareholder can dissent. The whole point of dissenters rights is to protect minority shareholders.
