If you move the sudo outside the if (and therefore run it every time) the code will call itself every time, and call itself, and call itself..........
The exit is necessary because otherwise you will drop through and try to run the remainder of the script as a non-root user. An alternate to the exit might be to drop the current script and re-start it with sudo like this:-

viewsudo
VIEW-OS(1) General Commands Manual VIEW-OS(1)NAME
viewsudo - execute a command as another (virtual) user
SYNOPSIS
viewsudo [-g groupname|#gid] [-u username|#uid] command
DESCRIPTION
viewsudo allows a user to execute a command as the superuser or
another user in View-OS.
OPTIONS
viewsudo accepts the following command line options:
-g group
Normally, viewsudo sets the primary group to root. The -g option causes sudo to run the specified command with the primary group set
to group. To specify a gid instead of a group name, use #gid. When running commands as a gid, many shells require that the '#' be
escaped with a backslash ('[u2019]). If no -u option is specified, the command will be run as the invoking user (not root). In
either case, the primary group will be set to group.
-u user
The -u option causes viewsudo to run the specified command as a user other than root. To specify a uid instead of a user name, use
#uid. When running commands as a uid, many shells require that the '#' be escaped with a backslash ('[u2019]).
RETURN VALUES
Upon successful execution of a program, the exit status from viewsudo will simply be the exit status of the program that was executed.
