Raoul Weil, the former head of UBS AG's global wealth management business accused of conspiring to help Americans evade taxes, was ordered to post bail of $10.5 million before trial, according to a court filing.

Weil, 54, appeared today in federal court in Fort Lauderdale, Florida, for the first time since he was indicted in October 2008 and declared a fugitive. U.S. Magistrate Judge Patrick Hunt said Weil must post a $9 million personal surety bond with a cash deposit of $4 million, as well as a $1 million corporate surety bond and a $500,000 personal surety bond, according to minutes of the hearing.

Weil's lawyer has said he is innocent. He is the highest-ranking banker among about 100 people charged since 2008 by the U.S. in a crackdown on offshore tax evasion. About three dozen foreign bankers, lawyers, and advisers were charged. Tax lawyers not involved in the case said they expect Weil to plead guilty, cooperate with prosecutors, and seek leniency at sentencing.
