boring re-raise question

[jkkkk]

I have 120BB, LP covers, EP has 100BB. LP is 33/8.

Party Poker 50NL (9 handed) converter

Preflop: Hero is BB with 4[img]/images/graemlins/heart.gif[/img], 5[img]/images/graemlins/heart.gif[/img].
3 calls, I check.

Flop: 2[img]/images/graemlins/club.gif[/img], 6[img]/images/graemlins/heart.gif[/img], 7[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, Hero bets $2 (pot), EP calls, LP min raises to $4, SB folds, Hero raises to $10..

How much should I be re-raising to here?

Is $10 ok?
