Credit Enhancement

Class A-F Credit Enhancement:
     1.   Excess spread;
     2.   Overcollateralization building up to a requirement of 2.30% of the 
          original loan balance of the Fixed Rate Loan Group;
     3.   Subordination of Class B-F certificates, initially totaling 4.70% of
          the original loan balance of the Fixed Rate Loan Group;
     4.   MBIA surety wrap.

Class B-F Credit Enhancement:
     1.   Excess spread;
     2.  Overcollateralization building up to a requirement of 2.30% of the
         original loan balance of the Fixed Rate Loan Group.


(1) Excess Spread
 o   Excess spread will generally equal the difference between the interest
     payments received on the aggregate home equity loans in the Fixed Rate
     Loan Group net of the Servicing Fee, Certificate Insurer Fee, Trustee Fee,
     and Certificate Interest.


(2) Overcollateralization
     1.  Before the Stepdown Date, overcollateralization initially builds to
         2.30% of the original loan balance of the Fixed Rate Loan Group
         (subject to rating agency and MBIA performance triggers);
     2.  On and after the Stepdown Date, and so long as no trigger event is in
         effect, the overcollateralization will step down monthly to 4.60% of
         the outstanding loan balance of the Fixed Rate Loan Group;
     3.  The overcollateralization step down will be subject to a floor of
         0.50% of the original loan balance of the Fixed Rate Loan Group
         (subject to rating agency and MBIA trigger events);
     4.  There will be no funding of the overcollateralization for the first 4
         months of the transaction (until May 1999).


(3) Subordination
 o   There will be a Class B-F Certificate in the amount of 4.70% of the
     original loan balance of the Fixed Rate Loan Group to provide credit
     enhancement to the Class A-F Certificates.


(4) Surety Wrap
 o   The Class A-F Certificates will have the benefit of an insurance
     guarantee with respect to the timely payment of interest and the ultimate
     payment of principal issued by MBIA.

                                   100.00%


Fixed Rate Loan Group Stepdown Date:
 o   The earlier to occur of: (i) the later of (x) the 37th Payment Date
     (January 2002) and (y) the first Payment Date on which the Class A-F
     Enhancement Percentage is at least 14.00% and (ii) when the Class A-F
     Certificates are retired.

Class A-F Principal Distribution Amount:
 o   Before the Stepdown Date, the Class A-F Certificates receive 100% of the
     collateral principal collections and the excess spread to build to a
     required overcollateralization target of 2.30%. After the Stepdown Date,
     the Class A-F Certificates receive principal distributions to maintain
     14.00% credit enhancement (assuming no Trigger Event is in effect).

Class A-F Enhancement Percentage:
 o   Percentage equivalent of a fraction, the numerator of which is the excess
     of (x) the outstanding loan balance of the Fixed Rate Loan Group for such
     Payment Date over (y) the Class A-F Certificate Principal Balance after
     taking into account the payment of the Class A-F Principal Distribution
     Amount on such Payment Date, assuming that no Delinquency Trigger Event is
     in effect and the denominator of which is the outstanding loan balance of
     the Fixed Rate Loan Group.

Fixed Rate Loan Group Delinquency Trigger:
 o   After the Stepdown Date, a Fixed Rate Loan Group Delinquency Trigger
     Event has occurred if on any Payment Date [85.25]% of the 3-month rolling
     average 60+ Day Delinquencies (including Bankruptcies, Foreclosures and
     REO properties) with respect to the Fixed Rate Loan Group equals or
     exceeds the Class A-F Enhancement Percentage (14.00% = 2.00 X 7.00%);
     i.e., when the 3-month rolling average of 60+ Day Delinquencies with
     respect to the Fixed Rate Loan Group equals or exceeds [16.42]% (14.00% /
     [85.25]%).
 o   If a Fixed Rate Loan Group Delinquency Trigger Event is in effect, the
     Class A-F Certificates will receive 100% of all principal until the credit
     enhancement equals or exceeds [85.25]% of the 3 Month Rolling Average of
     60+ Day Delinquencies with respect to the Fixed Rate Loan Group. During a
     Delinquency Trigger Event, overcollateralization will not be released.

Credit Enhancement

Class A-F Credit Enhancement:
     1.  Excess spread;
     2.  Overcollateralization building up to a requirement of 2.30% of the 
         original loan balance of the Fixed Rate Loan Group;
     3.  Subordination of Class B-F certificates, initially totaling 4.70% of
         the original loan balance of the Fixed Rate Loan Group;
     4.  MBIA surety wrap.

Class B-F Credit Enhancement:
     1.  Excess spread;
     2.  Overcollateralization building up to a requirement of 2.30% of the
         original loan balance of the Fixed Rate Loan Group.


(1) Excess Spread
o    Excess spread will generally equal the difference between the interest
     payments received on the aggregate home equity loans in the Fixed Rate
     Loan Group net of the Servicing Fee, Certificate Insurer Fee, Trustee Fee,
     and Certificate Interest.


(2) Overcollateralization
     1.  Before the Stepdown Date, overcollateralization initially builds to
         2.30% of the original loan balance of the Fixed Rate Loan Group
         (subject to rating agency and MBIA performance triggers);
     2.  On and after the Stepdown Date, and so long as no trigger event is in
         effect, the overcollateralization will step down monthly to 4.60% of
         the outstanding loan balance of the Fixed Rate Loan Group;
     3.  The overcollateralization step down will be subject to a floor of
         0.50% of the original loan balance of the Fixed Rate Loan Group
         (subject to rating agency and MBIA trigger events);
     4.  There will be no funding of the overcollateralization for the first 4
         months of the transaction (until May 1999).


(3) Subordination
o    There will be a Class B-F Certificate in the amount of 4.70% of the
     original loan balance of the Fixed Rate Loan Group to provide credit
     enhancement to the Class A-F Certificates.


(4) Surety Wrap
o    The Class A-F Certificates will have the benefit of an insurance
     guarantee with respect to the timely payment of interest and the ultimate
     payment of principal issued by MBIA.

   Note: Percentages may not add to 100.00% due to rounding.

                                   100.00%

Fixed Rate Loan Group Stepdown Date:
o    The earlier to occur of: (i) the later of (x) the 37th Payment Date
     (January 2002) and (y) the first Payment Date on which the Class A-F
     Enhancement Percentage is at least 14.00% and (ii) when the Class A-F
     Certificates are retired.

Class A-F Principal Distribution Amount:
o    Before the Stepdown Date, the Class A-F Certificates receive 100% of the
     collateral principal collections and the excess spread to build to a
     required overcollateralization target of 2.30%. After the Stepdown Date,
     the Class A-F Certificates receive principal distributions to maintain
     14.00% credit enhancement (assuming no Trigger Event is in effect).

Class A-F Enhancement Percentage:
o    Percentage equivalent of a fraction, the numerator of which is the excess
     of (x) the outstanding loan balance of the Fixed Rate Loan Group for such
     Payment Date over (y) the Class A-F Certificate Principal Balance after
     taking into account the payment of the Class A-F Principal Distribution
     Amount on such Payment Date, assuming that no Delinquency Trigger Event is
     in effect and the denominator of which is the outstanding loan balance of
     the Fixed Rate Loan Group.

Fixed Rate Loan Group Delinquency Trigger:
o    After the Stepdown Date, a Fixed Rate Loan Group Delinquency Trigger
     Event has occurred if on any Payment Date [85.25%] of the 3-month rolling
     average 60+ Day Delinquencies (including Bankruptcies, Foreclosures and
     REO properties) with respect to the Fixed Rate Loan Group equals or
     exceeds the Class A-F Enhancement Percentage (14.00% = 2.00 X 7.00%);
     i.e., when the 3-month rolling average of 60+ Day Delinquencies with
     respect to the Fixed Rate Loan Group equals or exceeds [16.42%] (14.00% /
     [85.25%]).

o    If a Fixed Rate Loan Group Delinquency Trigger Event is in effect, the
     Class A-F Certificates will receive 100% of all principal until the credit
     enhancement equals or exceeds [85.25%] of the 3 Month Rolling Average of
     60+ Day Delinquencies with respect to the Fixed Rate Loan Group. During a
     Delinquency Trigger Event, overcollateralization will not be released.
