                                HOME EQUITY LOANS

          The Home Equity Loans consist of both fixed rate and adjustable rate,
first lien, closed-end home equity loans. The adjustable rate loans are subject
to semi-annual interest rate adjustments after an initial six month, twenty-four
month, or thirty-six month period (the "Adjustable Rate Home Equity Loans"). All
Home Equity Loans which are not Adjustable Rate Loans are referred to herein as
"Fixed Rate Home Equity Loans". The obligations of the Obligor under each Home
Equity Contract are secured by the related real estate.

          The following pool of Home Equity Loans represents a statistical
summary of the final pool of Home Equity Loans that will be sold to the Trust at
Closing. The final pool of Home Equity Loans will differ slightly from the exact
pool underlying the summary characteristics of the Home Equity Loans shown
below, however the issuer does not expect that the characteristics of the final
pool of Home Equity Loans will vary materially from those of the Home Equity
Loans herein.
