Rick Broider, 34, of Loudon is eying another reality show. And this time the top prize is $10 million. Already a contestant on Wife Swap, Broider, a vice president for a software company and father of six boys, hopes to be chosen as one of 50 finalists for Tontine, a new show hosted by "Boston Rob" Mariano of Survivor fame.

Fifteen contestants, each given a key, will travel to the seven continents over 100 days and compete in various mental and physical challenges. The person with all 15 keys at the end unlocks $10 million, billed as the largest cash prize in the history of reality television. There's a catch, however: Contestants must contribute their net worth to compete. Those who lose, lose it all. Filming begins next month, and the show will premiere in the spring on a yet-to-be determined network.

Are you a reality TV junkie? We don't even watch TV. I heard about wife swapping online. It was an intriguing ad. But the only TV we watch is movies.

Are you nervous about losing your life savings? If I was anyone else I would say yeah, but I've come from nothing. Even if I had to start all over again, I've had a big head start off of where I started from. We've bounced back pretty good. I don't intend to lose. But anything is possible, so I'm prepared to deal with the consequences. And I've got a great family. We stick together.

How does your wife feel about this gamble? Any good man will probably say this, but I have the best wife in the world. She has complete confidence in me, and she knows I'm a tenacious competitor. She knows that there is nothing I won't do. If it's within my will, I will win and I will bring the gold for New Hampshire and do some good things for our community.

Like what? One of our dreams is a local sports center. The world has a lot of problems. One of the things we may be able to do is attack it at the root and help kids out in learning how to make good choices and being more responsible and accountable.

What does competing on these shows say about you? I have a big personality. I seem to be attracted to things that have limited odds or seem impossible.
