I fold this. You don't have a made hand yet and if you call and miss the flop, you are down 100 chips if UTG bets. For 15 chips, I don't think it's worth the risk.

Edit: What do you do if there are a bunch of limpers in level 1 and you have AK in the BB? I usually check to see a flop and bet out if I hit, check/fold if I miss.
