Exhibitor must deliver written notice to WAE of any cancellation. If written notice of cancellation is received by WAE before Dec. 1, 2016, the exhibitor shall forfeit 20% of the total space fee and shall be entitled to an 80% maximum refund. Cancellation on Dec. 1, 2016, and hereafter by the exhibitor, shall result in forfeiture of the entire space fee. Exhibitor agrees that these charges are reasonably related to WAE damages. By cancelling space, the exhibitor loses all rights or claims to the space and WAE may rent it to others. This policy also applies to partial cancellation and exhibit downsizing.
