If the original health spa contract complies with the chapter, or was entered into prior to January 1, 1989, the exercise of options to renew health spa contracts at a prorated price less than the original contract price may be accomplished by a separate written agreement devised by the health spa without regard to the provisions of §§ 4205 and 4206 of this title; provided however, that all regulatory provisions of this chapter including, without limitation, refund and fee provisions shall continue to apply. Notwithstanding the foregoing, any member of a health spa may demand to execute a renewal contract in compliance with the provisions of this chapter.
