Before revision:   We aim at establishing explicitly the value of such a loan and ranges of fair values of key parameters : this loan size, interest rate,  fee for providing such a service and quantity of this automatic termination clause and relationships among these parameters as well as the optimal terminable stopping times .
After revision:  We aim at establishing explicitly the value of such a loan and ranges of fair values of key parameters : this loan size, interest rate, fee for providing such a service and quantity of this automatic termination clause and relationships among these parameters as well as the optimal exercise times. We present numerical results and make analysis about the model parameters and how they impact on value of stock loan .
