in excess of the amounts permitted to be retained pursuant to
subdivision two of this section.
4. Cancellation. Cancellation shall occur:
(a) when the buyer mails to the seller notice of his intent to cancel,
or
(b) where the seller has actual notice of the buyer's intention to
cancel, or
(c) where the buyer fails to attend consecutive scheduled classes or
lessons constituting at least twenty-five percent of the total lessons
or time contracted for, without informing the seller in writing that he
intends to remain enrolled.
5. The contract forms used by the seller shall conspicuously disclose
the seller's cancellation provisions in compliance with subdivisions

notice in ten point bold face type:
If you cancel this contract (the seller) may keep only five percent of
the cash price, but not to exceed fifty dollars, and a portion of the
contract price based upon the lessons or services you have used. You may
notify the seller of your intent to cancel by mail, addressed to (the
seller) at (seller's address).
6. Nothing in this section shall be construed so as to nullify or
impair any right or rights which a buyer may have against a seller at
common law, by statute, or otherwise.
