He's the former brokerage assistant who helped Martha Stewart make the stock trade that earned her a prison sentence.
The sentence for Douglas Faneuil is a $2,000 fine. He was spared both prison and probation.
The 28-year-old Faneuil apologized to the federal judge, saying "thankfully I've learned my lesson."
He had faced up to a year in prison after pleading guilty to the misdemeanor charge of accepting a payoff.
Prosecutors urged the judge to spare Faneuil time behind bars after his testimony helped win Stewart's conviction in federal court.
A week ago, Stewart herself was sentenced to five months in prison and five months of home detention for lying to authorities about her sale of ImClone Systems shares. She remains free while the case is on appeal.
