I would think long and hard before giving someone ten percent of the company just for making the occasional phone call, when you will be expecting people to bust their asses for much less. I might do it if everything else so indicated strongly enough. But if the negatives seem likely to be as heavy as the positives? No way. This, mind you, does not constitute drawing any conclusions about whether he's a good or bad person. It just needs a straight pragmatic business decision.
