Right of first refusal on private company stock sale
Currently own private company stock valued by an independent 3rd party and approved by the board at $10/share. I have a purchaser willing to purchase my shares at $5. Since they will have no rights upon purchase they are not willing to pay full value. Company has right of first refusal and could purchase for $5. However they have twice in the past purchased shares outright (not under the right refusal right) at a price equal to the independnet 3rd party/board approved value. Do I have a case here as far as hiring a lawyer on a contingency fee basis to get the difference between $5 right of first refusal price and $10 fair value?
