Notes:

The servicer may in its reasonable discretion make advances to pay off a first lien mortgage so that upon the servicer's foreclosure of the second mortgage, the property will be acquired free and clear of the first lien. When the sale of the acquired property is completed, such advances will be reimbursed from the sales proceeds.
