interesting "bubble" situation

[gumpzilla]

So the following just happened to me. There are five players remaining in a Stars SNG. The one to my immediate right has been away for the entire SNG, and has just under 2 BB's remaining (big blind is 200) before posting the BB, where he is now. I'm the short stack among the 4 actually present players with 5.5 BB's UTG. The two big stacks each have something like 25 BB's, and a 7 BB stack is in the SB.

What range do you push UTG in this situation? What variables would you take into account that I've passed over?
