Yea I'll have to find some term sheets laying around, but I can't remember seeing the 90 day exercise being explicitly written into most term sheets. I only have seen it written into people's offer letters. Does anybody know where that language would be written actually otherwise? Some sort of bylaws or something -- seems like that could be relatively easily changed to read something like "exercise period of employee stock options is 90 days after termination of employment unless otherwise stated in employee offer letter and should not be greater than 10 years."
