A motor vehicle fuel franchise agreement may not require a security deposit except for the purpose of securing against loss of or damage to property. The dealer may satisfy any security deposit required by depositing cash or pledging a savings account or its equivalent in a financial institution in this state. Earnings accruing on a savings account or its equivalent are the property of the dealer and the dealer may withdraw the earnings annually from the account.
