As between IBCJ and IMCT, IBCJ shall be liable as if it were sole principle debtor and not merely a surety. Accordingly, it shall not be discharged, nor shall its liability be affected, by anything which would not discharge it or affect its liability if it were the sole principle debtor, including but not limited to anytime, indulgence, concession, waiver or consent at anytime given to IBCT, IBCJ or any other person.
