Except where required by mandatory operation of law, LAARMANN will not be liable for any personal injury, indirect, special
or consequential loss or damage (including loss of profits, loss of opportunity or business interruption), suffered by the
Customer or any other person arising directly or indirectly out of the goods supplied by LAARMANN.
