Petz, I didn't mean to infer that Rivet wasn't worth what ever the price was. Nor, did I have an inkling of $210k you mentioned.
As I understood, the deal would cost Rivet the vested Options/Shares he had accumulate from Moto. IIRC, AMD was obliged to compensate Mr Rivet for that loss. That would explain "if" the costs were out of line.
Please don't invest in any company I try to run. :-)
