Anna granted Belle the exclusive right to sell her brand of leather bags in Tarlac, the price for her merchandise payable within 60 days from delivery, with or without a resale, and promising Belle a commission of 20% on all sales. After the delivery of the merchandise to Belle but before she could sell any of them, Belle's store in Tarlac was completely burned without her fault, together with all of Anna's leather bags. Belle does not want to pay for the lost leather bags and claims that the contract she entered into with Anna is an agency to sell.

Must Belle pay Anna for the lost leather bags? Why or why not?
