Note: exit in a function is just return, not exit of parent script with bad usage. This is why it is good to segregate functions, as they are almost sub-shells, and if you pipe where you call them, they may be subshells.
Scrutinizer is right. The "exit" gets you out of the entire script, which is exactly what you want if you have bad parameters. A "return" finishes a function without having to drop through to the last line of the function.
