Two executives at Research in Motion (RIM) will pay another $2.5 million each as part of a tentative settlement reached with one of its shareholders over the company's option granting policy. The Blackberry-maker said Friday that it had reached that agreement with the Ironworkers Ontario Pension Fund, which launched legal action earlier this year. The fund had been seeking $105 million in damages. The $2.5 million today comes on top of the $5 million they've each already agreed to repay to the company to defray its costs for conducting the investigation. The two men continue to share the title of CEO and hold significant shares, but stepped down as Chairman of the Board.
