weird big draw in multiway pot

[hoyasaxa]

Live .25/.50 game

BB is very aggro PF and postflop, UTG is total lagtard

Two limpers, hero calls from sb with 52h. BB raises to two, UTG calls, other limper folds, hero calls (i love these hands please dont say fold pf).

Flop is 10 9 5, two hearts, giving me a potentially huge draw. Hero checks, BB bets $3.50, UTG calls.

I have an all purpose hand. I can call, raise, or fold.
My thinking is that BB either has an overpair or top pair, against which im a slight favorite. Not really sure what UTG has, maybe a weak 10, but possibly a set hes slowplaying or a higher flush draw, maybe a straight draw.

What do I do here?
