Collateral:                     Fixed and floating-rate conventional home equity
                                loans secured by first and second lien
                                mortgages. See "Collateral Description" on page
                                7 for more detail.

Prepayment Speed:

Fixed-Rate Certificates:        All classes are priced at a prepayment speed of
                                100% of the prepayment assumption ("PPC"). 100%
                                PPC describes prepayments starting at 4.0% CPR
                                in month 1, increasing by approximately 1.454%
                                CPR per month to 20% CPR in month 12, and
                                remaining at 20% CPR thereafter.

Floating-Rate Certificates:     Constant 25% CPR.

Expected Pricing Date:          September 3 - 4, 1997

Expected Settlement:            September 17, 1997 through DTC, Euroclear or 
                                CEDEL.

Distribution Dates:             The 25th of each month, beginning October, 1997


Prefunded Amount:               $137.3 million

Subordinate IO:                 The certificates will include a Subordinate IO
                                strip off of the fixed rate and ARM pools which
                                are not offered hereby. The fixed rate pool
                                Subordinate IO pays a 15% coupon for the first
                                24 months based on its notional principal
                                balance (defined as the lesser of approximately
                                $26.6 million and the current outstanding fixed
                                rate pool balance). The ARM pool Subordinate IO
                                pays a 7.50% coupon for the first 24 months
                                based on its notional principal balance (defined
                                as the lesser of approximately $68.4 million and
                                the current outstanding ARM pool balance).

                                The fixed  rate pool  Subordinate  IO  initially
                                reduces the excess spread  available to fund o/c
                                by approximately  150 basis points (resulting in
                                a  fixed  pool  initial   excess   servicing  of
                                approximately   1.50%),   while   the  ARM  pool
                                Subordinate  IO initially  reduces the excess by
                                approximately  75 basis points  (resulting in an
                                ARM   pool   initial    excess    servicing   of
                                approximately 2.70%).

Available Funds Cap:            All Certificates are subject to an available
                                funds cap. The cap, for both the fixed rate or
                                ARM groups, is the weighted average coupon for
                                that group less the approximately 0.50%
                                Servicing Fee. Shortfalls due to the available
                                funds cap will NOT be carried forward.

Option and Auction Call:        10% mandatory auction call (10% of original
                                certificate balance) followed by a 5% servicer
                                clean-up call.

Coupon Step Up:                 After the Clean-up Date, the spread to LIBOR on
                                the Class A-10 will double, while the spread to
