There is a built-in SECONDS variable you can use... When it becomes greater than 14400, 4 hours will have passed.

Code:
#!/bin/sh

T=$((60*60*4))

# while file1 doesn't exist, or file2 doesn't exist, or file3 doesn't exist, ...
while [ ! -e file1 ] || [ ! -e file2 ] || [ ! -e file3 ] || 
        [ ! -e file4 ] || [ ! -e file5 ] || [ ! -e file6 ] ||
        [ ! -e file7 ]
do
        # wait another minute for files to appear
        sleep 60
        # Break loop if we've waited longer than 4 hours.
        [ "$SECONDS" -gt $T ] && break
done

# Quit if 4 hours exceeded
if [ "$SECONDS" -gt $T ]
then
        echo "timed out"
else
        echo "got files"
fi | mailx -s "subject" person@addr
