Since you mentioned you have encrypted DB, you need to have Oracle Wallet open, if we assume db instance is up, is already open.
I do not think you can/should use "exp" utility. It's replaced by more powerful "expdp" and "impdp" utilities. These two utilities will allow you to successful backup/restore encrypted data.
Please look into Oracle Utilities guide for further command line reference. Generally for expdp you need to use ENCRYPTION and ENCRYPTION_PASSWORD and you may or may not use Oracle Wallet.
My preffered way though, to use RMAN.
