An exception is a general term for a situation or condition that occurred. Usually exceptions are errors. An unhandled exception is when there is not a check for a specific error condition that caused the error.
The address you referenced doesn't really help at all, because that is just the hex address located in memory where the program is running and the particular piece of data was accessed.
You'll need to be more specific when you say you're getting an exception.
