specified duties, unless otherwise agreed in writing by the seller

shall have the option to make alternative arrangements for

compliance with the covenants. Within a reasonable time after

amount, and any revised payment schedule and, if the duties of the

buyer performed by the seller pertain to insurance, a brief

description of the insurance paid for by the seller including the

pursuant to subsection (1) at a rate not exceeding the rate stated

to the buyer pursuant to the provisions on disclosure (Part 3) with

respect to the sale, refinancing, or consolidation, except that with

respect to a revolving charge account the amount of the advance may

be added to the unpaid balance of the account and the seller may

make a credit service charge not exceeding that permitted by the

provisions on credit service charge for revolving charge accounts
