You can set user as mandatory by testing if it's set (although you may want to use another variable name (USER is a shell variable)):

i.e.
Code:
while getops ...; do
  ...
done
...
if [ -z "$USR" ]; then
  usage
  exit 1
fi

EXCEPTION=${EXCEPTION:-some_default} # set default to 'some_default' if not given
