This right of cancellation may not be waived by any purchaser or by any other person on behalf of the purchaser. Furthermore, no closing may occur until the cancellation period of the time-share purchaser has expired. Any attempt to obtain a waiver of the cancellation right of the time-share purchaser, or to hold a closing prior to the expiration of the cancellation period, is unlawful and such closing is voidable at the option of the purchaser for a period of one (1) year after the expiration of the cancellation period.
