well, you can also go to the relevant authorities like employee
dunno what union or association to see if you can rescind the
contract.
Or go to court, but then more expensive loh... 
Else, although they put there, they may not act on the terms also
can.
You can also puay with the HR or your boss to ask if you want to
quit, can they not act on the terms there. Sometimes, they are kind
enough not to ask you to pay...it all depends.
