With no explanation, chose the best option from "A", "B", "C" or "D". to exercise its option to accelerate, it was not required to give Crystal notice of its intent to apply the default interest rate. Crystal counters that despite the language in the contract, a creditor must take affirmative action to put the debtor on notice that it intends to exercise its option to accelerate.

Both state and federal courts have made clear the unquestionable principle that, even when the terms of a note do not require notice or demand as a prerequisite to accelerating a note, the holder must take affirmative action to notify the debtor that it intends to accelerate. See Green v. Carlstrom, 212 Cal.App.2d 240, 243, 27 Cal.Rptr. 850 (1963) (<HOLDING>) (citation omitted); Trigg v. Arnott, 22
