I need a financial incentive example for whistle blowing. Or a reward system that would encourage whistle blowing.

The financial incentive is that you get your butt kicked by everyone except your local church.

(Note: The Sarbanes Oxley Act has made it illegal to retaliate against whistle blowers who report securities fraud. There may be other laws that apply to your specific situation, but there are usually no rewards. My advice: always report, and always report anonymously.)
