Bash Switch Statement and Executing Multiple Programs

I'm trying to use a Bash switch statement to execute a set of programs. The programs are run through the terminal via a script. The simple idea is ::

In the terminal : ./shell.sh
Program asks : "What number?"
I input : 1

Program processes as:

prog="1"
case $prog in
1) exec gimp && exec mirage ;;
esac

I've tried it several ways yet nothing will run the second program and free the terminal. The first program runs fine and frees the terminal after closing. What am I to put after executing the first program that will allow the second to run in tandem with the first and also free the terminal?

To run two commands in the background, use & after each of them:

case $prog in 
    1)  
        gimp &
        mirage &
        ;;
esac

exec basically means "start running this program instead of continuing with this script"
