(1) If the agreement with respect to a consumer credit transaction contains covenants by the consumer to perform certain duties pertaining to insuring or preserving collateral, and the creditor pursuant to the agreement pays for performance of the duties on behalf of the consumer, the creditor may add the amounts paid to the debt if:

(a) The expenditure is reasonable to protect the risk of loss or damage to the property;

(b) The creditor has mailed to the consumer, at the consumer's last known address, written notice of the consumer's nonperformance and has given the consumer reasonable opportunity after such notice to so perform; and

(c) In the absence of performance, the creditor has made all expenditures on behalf of the consumer in good faith and in a commercially reasonable manner.

(2) Within a reasonable time after advancing any sums, the creditor shall state to the consumer in writing the amount of the sums advanced, any charges with respect to this amount, and any revised payment schedule, and, if the duties of the consumer performed by the creditor pertain to insurance, a brief description of the insurance paid for by the creditor including the type and amount of coverage. No further information need be given.

(3) A finance charge may be made for sums advanced pursuant to this section at a rate not exceeding the rate stated to the consumer pursuant to the provisions on disclosure contained in section 5-3-101 with respect to the consumer credit transaction; except that, with respect to a revolving account, the amount of the advance may be added to the unpaid balance of the debt and the creditor may make a finance charge not exceeding that permitted by the provisions on finance charges.
