I don't like that at all.

for index1 = 1 to 10 do
  for index2 = 1 to 10 do
    if (condition) then
      exit(2)
    end if
  end for
end for
--exit(2) was here.

for index1 = 1 to 10 do
  for index3 = 1 to 15 do
    for index2 = 1 to 10 do
      if (condition) then
        exit(2)
      end if
    end for
  end for
  --exit(2) is now here
end for
--exit(2) was here.

A reasonable change to the code changed the exit point.
exit label makes more sense.
