I’ve possibly read the wrong $100k & $150k numbers; here’s a USADA report about $1mm+ paid to Dr Ferrari from 1996 to 2009:

Don’t know how much credence to put into it, though. But I know when I was reading many articles, on Sat-Sun, about this controversy, I did see the $100 & $150k fees paid to him, in some article, somewhere. It appears that they have his bank/financial records.
In the report it shows the largest payments were for the 5 years 2002 thru 2006 for over a million dollars, averaging $200,000/yr over those 5 years.
