LIMITATIONS AND DAMAGES DISCLAIMER:
In no event shall Central be liable for any collateral, indirect,
punitive, incidental, consequential, or exemplary damages in connection with or arising out of a purchase order
or contract or the use of products provided hereunder, regardless of whether Central has been advised of
