John, I’m thinking that one of the greatest risks might be that your buyer has some undefined incentive to under-report whatever varying profits that will be made. Different types of businesses offer different kinds of opportunities for such under-reporting. (As an example, the movie, recordings, and entertainment industry is notorious for finding such ways in order to skin their performers.)
I don’t know what kind of business you’re considering selling, nor is it any of my business. Whatever level of under-reporting opportunity risk there might be in your line of business needs to be matched in the language of your performance note by a required auditing process sufficient to protect your interest. Skinning the IRS is one thing; skinning you would become very personal. Failure to execute that risk-commensurate level of diligent auditing should have severe consequences — in your favor.
