Bernard Katz was reelected to Helionetics’ board.

The Santa Ana high-technology company’s directors returned the Beverly Hills financier to the board just 10 months after pressuring him to resign. Wilson K. Talley, who had been serving as acting chairman, was elected chairman; Michael Mann, acting president for a month, was named president and chief executive. Katz, the company’s largest shareholder, was removed from company operations to ease Wall Street concerns about his controversial business past.
