he worked for Symbion health with deep understanding of there financial's there, perhaps there is some strategic fit between the two and possibly a third company? Due diligence may have shown that the company was worth a lot more than offered, if it is to be sold why would he come back, only to find another job in 12 - 18 months? I think you would have to take it as a positive, although how positive remains to be answered.
