89s in multi-way raised pot

[poboy]

Haven't been at table long but villians seem pretty typical LAG.

PokerStars No-Limit Hold'em, $0.50 BB (8 handed) converter

BB ($31.60)
UTG ($49.80)
UTG+1 ($81.85)
MP1 ($59.90)
MP2 ($48.95)
Hero ($45.75)
Button ($59.55)
SB ($12.85)

Preflop: Hero is CO with 9[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/heart.gif[/img].
<font color="#666666">1 fold</font>, UTG+1 calls $0.50, MP1 calls $0.50, MP2 calls $0.50, <font color="#CC3333">Hero raises to $3.5</font>, <font color="#666666">3 folds</font>, UTG+1 calls $3, MP1 calls $3, MP2 calls $3.

Flop: ($14.75) Q[img]/images/graemlins/heart.gif[/img], 2[img]/images/graemlins/heart.gif[/img], T[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">UTG+1 bets $5</font>, <font color="#CC3333">MP1 raises to $10</font>, MP2 calls $10, Hero ????

What do you do and why?
