(2) A creditor in consumer loan transactions shall be subject to all of the defenses of the borrower arising from the consumer sale or lease for which the proceeds of the loan are used, if the creditor knowingly participated in or was directly connected with the consumer sale or lease transaction. Without limiting the scope of the preceding paragraph, a creditor shall be deemed to have knowingly participated in or to have been directly connected with a consumer sale or lease transaction if:
(a) He was a person related to the seller or lessor;(b) The seller or lessor prepared documents used in connection with the loan;(c) The creditor supplied forms to the seller or lessor which were used by the consumer in obtaining the loan;(d) The creditor was specifically recommended by the seller or lessor to the borrower, and made two or more loans in any calendar year, the proceeds of which are used in transactions with the same seller or lessor; or(e) The creditor was the issuer of a credit card which may be used by the consumer in the sale or lease transaction as a result of a prior agreement between the issuer and the seller or lessor. Any creditor who participates in a transaction which violates this rule, or knows or should have reason to know that a seller's practices may violate this rule, shall be deemed to be engaging in an unfair and deceptive trade practice. Any creditor who attempts to enforce a note, instrument, or other evidence of the buyer's indebtedness arising out of a transaction which violates this rule shall be deemed to be engaging in an unfair or deceptive trade practice.
