Xerox Corp.’s top executive and six board members agreed to step down in a victory for Carl Icahn’s battle against the company’s planned $6.1 billion takeover by Fujifilm Holdings Corp. The resignations, which include Chief Executive Officer Jeffrey Jacobson and Chairman Robert Keegan, are part of an agreement with activist investors to settle a lawsuit that will put in place executives close to Icahn. Keith Cozza, CEO of Icahn Enterprises, is expected to be elected chairman while John Visentin, who has been a consultant to Icahn in the feud against Xerox, is slated to be appointed as its new CEO.
