The developer shall not sell, lease, assign, or otherwise transfer the entire interest of the developer, other than as a transfer of a time-share interval in the normal course of marketing, in the time-share program or the accommodations or facilities to a third party when such a sale, lease, assignment, or other transfer substantially affects the rights of other owners of the time-share units, unless:

(1) The third party agrees in writing to honor fully the rights of purchasers of the time-share intervals to occupy and use the accommodations or facilities or agrees in writing to purchase the interval in an amount equal to the amount actually paid by the purchaser toward the purchase price of the time-share interval;

(2) The third party agrees in writing to honor fully the rights of purchasers of the time-share intervals to cancel their sales agreement and receive any refunds due;

(3) The third party agrees in writing to comply with the provisions of this article for as long as the third party continues to sell the time-share project or for as long as purchasers of the time-share project are entitled to occupy the accommodations or use the facilities, whichever is longer in time; and

(4) Written notice is given to the association and notice shall be sent by certified mail or statutory overnight delivery within 30 days of the sale, lease, assignment, or other transfer.
