H-P (HPQ) chairman Ray Lane steps down. Director/activist investor Ralph Whitworth will serve as interim chairman while the company looks for a permanent replacement. Lane had come under fire in recent weeks from H-P investors and shareholder advisory firm ISS, but had been re-elected at last month's shareholder meeting. Update: Though stepping down as chairman, Lane remains a director. But John Hammergren and G. Kennedy Thompson are resigning from the board.
