Okay,

How about...

paste file1 file2 | while read LINE ; do
  f1=$(echo $LINE | awk '{print $1}')
  f2=$(echo $LINE | awk '{print $2}')

  echo "f1 is $f1 and f2 is $f2"

  # Do stuff with $f1 and $f2 here

done

  f1=$(echo $LINE | awk '{print $1}')
  f2=$(echo $LINE | awk '{print $2}')

  echo "f1 is $f1 and f2 is $f2"

  # Do stuff with $f1 and $f2 here
