Two former accountants at Cisco Systems, the maker of equipment to link computers, were indicted Thursday by a federal jury here for wire and computer fraud, prosecutors said.

Geoffrey Osowski of Mountain View, Calif., and Wilson Tang of Palo Alto, Calif., are accused of twice transferring Cisco stock, worth a total of $6.3 million, into their personal brokerage accounts this year and selling it, the U.S. attorney's office said in a statement. After the first incident, Osowski bought, among other things, a 2001 Mercedes 320 for $52,000; a diamond ring for $44,000; and a Rolex watch for $20,000, the government alleges. The indictment contains one count of conspiracy to commit computer and wire fraud, one count of computer fraud and three counts of wire fraud. The maximum sentence for each count is five years imprisonment and a fine of $250,000. The defendants are scheduled to return to court on April 12 for arraignment. "We brought this to the attention of law enforcement, and we fully support their efforts to prosecute," said Steve Langdon, a Cisco spokesman. Neither Osowski nor Tang was immediately available to comment.
