(a) General effectiveness. Except as otherwise provided in the Uniform Commercial Code, a security agreement is effective according to its terms between the parties, against purchasers of the collateral, and against creditors.
(b) Applicable consumer laws and other law. A transaction subject to this article is subject to any applicable rule of law which establishes a different rule for consumers, to any other statute or regulation of this state that regulates the rates, charges, agreements, and practices for loans, credit sales or other extensions of credit, and to any consumer-protection statute or regulation of this state.
