I was wrong. The last live tournament I played in was the Borgata Open. I still have the rules. Rule 13 states:

A player that exposes their cards during play will receive a warning but will not have their hand declared dead. any subsequent exposing of their hand will result in having their hand declared dead, time penalties, and possible expulsion from the tournament. 10 - 20 - 30 minutes away from the table will be used.

Also, we have rule 29:

Penalties: A penalty may be invoked if a player exposes any card with action pending, etc. etc. Penalties will be invoked in cases of abuse, disruptive behavior, and similar incidents. Penalties will start with 10 minutes away from the table, and can go up to expulsion from the tournament.

So, if this is his first offense, his hand is live and he gets a warning.

I know that at both the Tropicana and Taj Mahal in Atlantic City, the hand would be dead. The Borgata uses more 'Las Vegas-like' rules rather than standard AC rules. So, again, it depends on the rules of the house and/or the tournament.
