I was at a start-up -- that I co-founded, so I take some of the blame here in not realizing what another co-founder was baking into the cake, but at least I can warn others now -- where the company interpreted "right of first refusal" as "the person trying to sell shares must hire an outside auditor to determine FMV," and refusing to answer any further questions about whether the auditor would actually be given access to the company's books.
