Shell script kill background process on quit

I have a script like this:

#!/bin/sh
exec ./cmd1&
exec ./cmd2

If I kill the script only cmd2 is killed, cmd1 keeps running. Is it possible that both processes quit automatically?

do not do second exec (the first one is redundant, too) but leave the shell wait for it. killing the shell may kill the commands; if not - then:

    trap 'kill -15 $kids; exit 143' TERM
    cmd1 &
    kids=$!
    cmd2 &
    kids="$kids $!"
    wait
