What is the bank decision when I want to terminate my time deposit account?

I opened a time deposit account in the bank last year and the withdrawal date of it is on May 2011. There is a emergency which I have to withdraw at least 75% of the amount. Can a bank allowed me to withdraw the said amount even the due date is not yet over? What about the penalty and interest of it?|||The penalty will be subtracted from the amount remaining in the account.
