(a) A person required to deliver a public offering statement pursuant to section 4-102(c) shall provide a purchaser with a copy of the public offering statement and all amendments thereto before conveyance of the unit, and not later than the date of any contract of sale. Unless a purchaser is given the public offering statement more than fifteen days before execution of a contract for the purchase of a unit, the purchaser, before conveyance, may cancel the contract within fifteen days after first receiving the public offering statement.
(b) If a purchaser elects to cancel a contract pursuant to subsection (a), he may do so by hand delivering notice thereof to the offeror or by mailing notice thereof by prepaid United States mail to the offeror or to his agent for service of process. Cancellation is without penalty, and all payments made by the purchaser before cancellation must be refunded promptly.
(c) If a person required to deliver a public offering statement pursuant to section 4-102(c) fails to provide a purchaser to whom a unit is conveyed with that public offering statement and all amendments thereto as required by subsection (a), the purchaser, in addition to any rights to damages or other relief, is entitled to receive from that person an amount equal to ten percent of the sale price of the unit, plus ten percent of the share, proportionate to his common expense liability, of any indebtedness of the association secured by security interests encumbering the common interest community: Provided, That purchaser must show that he or she has been actually damaged as a result of the failure to provide such offering statement and that his or her action to recover such damage and the penalty provided in this subsection is instituted within three years from the date on which purchaser's right of action shall have accrued.
