provided by AMRESCO Residential Capital Markets, Inc. with respect to the
expected characteristics of the pool of home equity loans in which these
securities will represent undivided beneficial interests. The actual
characteristics and performance of the home equity loans will differ from the
assumptions used in preparing these materials, which are hypothetical in nature.
Changes in the assumptions may have a material impact on the information set
forth in these materials. No representation is made that any performance or
return indicated herein will be achieved. For example, it is very unlikely that
the loans will prepay at a constant rate or follow a predictable pattern. This

initial offer or sale of these securities to you to the extent set forth below.

any security or instrument or to participate in any particular trading strategy.

Distribution Dates:          The 25th of each month, beginning October, 1998

Credit Enhancement:
- -------------------

    Overcollateralization:   The Group I certificates will benefit from
                             overcollateralization which is initially 0% and
                             increases to 2.0% of the original pool balance
                             through the allocation of excess spread. The Group
                             II certificates will benefit from
                             overcollateralization which is initially 0% and
                             increases to 2.5% of the original pool balance
                             through the allocation of excess spread.

    Subordination:           Classes A-1 through A-6 will benefit from 2.25% in
                             subordinate certificates, and classes A-7 and A-8
                             will benefit from 20.25% in subordinate
                             certificates.

    Freddie Mac
    Guarantee:               The fixed rate (i.e., Group I) certificates will
                             benefit from a Freddie Mac guarantee.

    O/C Step-Down:           The required overcollateralization can also "step-
                             down" after the later of (i) 36 months and (ii)
                             when the Senior Enhancement Percentage is greater
                             than 8.5%, to the greater of:
                             --   The product of (i) two times the base
                                  overcollateralization requirement (i.e., 4.0%
                                  for the Group I pool and 5.0% for the Group II
                                  pool) and (ii) the outstanding pool balance;
                             --   0.50% of the original related pool balance
                                 (i.e., the o/c floor);

    Excess Spread:           Current period losses will be covered by any excess
                             spread available in that period.

    Crosscollateralization:  Excess spread available on the Group I fixed-rate
                             portfolio will be made available to cover losses on
                             the Group II certificates, but not the reverse.

Subordinate IO:              The certificates will include a Subordinate IO
                             strip off of the Group I and Group II pools which
                             are not offered hereby. The Group I pool
                             Subordinate IO pays a 7.5% coupon for the first 24
                             months based on its notional principal balance. The
                             Group II pool Subordinate IO pays a 3.0% coupon for
                             the first 24 months based on its notional principal
                             balance.

Available Funds Cap:         All Certificates are subject to an available funds
                             cap. The cap, for both the Group I and Group II
                             pools, is the weighted average coupon for that
                             group less the approximately 0.50% Servicing Fee.
                             Shortfalls due to the available funds cap will be
                             carried forward on the adjustable rate certificates
                             ONLY.

Interest Carry Forward:      Any interest due but not paid to the certificates
                             is carried forward and paid in future periods to
                             the extent interest funds are available. Any
                             Interest Carry Forward amount WILL earn interest at
                             the current certificate rate.

Basis Risk Carry Forward:    Any interest due to class A-7 based on its coupon
                             formula but not paid due to the available funds cap
                             may be paid from amounts which would otherwise be
                             paid to the residual. While these amounts due can
                             be carried forward, they will not accrue interest.

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

Coupon Step Up:              Two months after the Auction Call Date, the spread
                             to LIBOR on the Class A-7 will double, while the
                             spread to LIBOR on the M-1A, M-2A, and B-1A will
                             increase by 50% to incent AMRESCO to call the
                             bonds. The coupon on the Class A-5 certificates
                             also will increase by 0.75%.

Tax Status:                  REMIC

ERISA Eligibility:           The Class A-1 through A-8 certificates are ERISA
                             eligible; All other Certificate Classes are NOT
                             ERISA eligible.

SMMEA Eligibility:           Only the Class A-7, A-8 and M-1A Certificates are
                             SMMEA eligible.

NOTES:
- ------
(1)  The period of delinquency is based on the number of days payments are
     contractually past due. The delinquency statistics for the period include
     loans in foreclosure.
(2)  REO Properties (i.e., "real estate owned" properties - properties relating
     to mortgage foreclosed or for which deeds in lieu of foreclosure have been
     accepted, and held by the Servicer pending disposition) percentages are
     calculated using the number of loans, not the dollar amount.
(3)  "Foreclosure Rate" is the number of mortgage loans or the dollar amount of
     mortgage loans in foreclosure as a percentage of the total number of
     mortgage loans or the dollar amount of mortgage loans, as the case may be,
     as of the date indicated.

This information has been prepared in connection with the issuance of securities
representing interests in the above trust, and is based in part on information  
provided by AMRESCO Residential Capital Markets, Inc. with respect to the       
expected characteristics of the pool of home equity loans in which these        
securities will represent undivided beneficial interests. The actual            
characteristics and performance of the home equity loans will differ from the   
assumptions used in preparing these materials, which are hypothetical in nature.
Changes in the assumptions may have a material impact on the information set    
forth in these materials. No representation is made that any performance or     
return indicated herein will be achieved. For example, it is very unlikely that 
the loans will prepay at a constant rate or follow a predictable pattern. This

expected characteristics of the pool of home equity loans in which these        
securities will represent undivided beneficial interests. The actual

This information has been prepared in connection with the issuance of securities
representing interests in the above trust, and is based in part on information  
provided by AMRESCO Residential Capital Markets, Inc. with respect to the       
expected characteristics of the pool of home equity loans in which these        
securities will represent undivided beneficial interests. The actual            
characteristics and performance of the home equity loans will differ from the   
assumptions used in preparing these materials, which are hypothetical in nature.
Changes in the assumptions may have a material impact on the information set    
forth in these materials. No representation is made that any performance or     
return indicated herein will be achieved. For example, it is very unlikely that 
the loans will prepay at a constant rate or follow a predictable pattern. This  
information may not be used or otherwise disseminated in connection with the    
offer or sale of these or any other securities, except in connection with the   
initial offer or sale of these securities to you to the extent set forth below.

PROSPECTUS AND PROSPECTUS SUPPLEMENT WILL CONTAIN ALL MATERIAL INFORMATION IN

This information has been prepared in connection with the issuance of securities
representing interests in the above trust, and is based in part on information
provided by AMRESCO Residential Capital Markets, Inc. with respect to the
expected characteristics of the pool of home equity loans in which these
securities will represent undivided beneficial interests. The actual
characteristics and performance of the home equity loans will differ from the
assumptions used in preparing these materials, which are hypothetical in nature.
Changes in the assumptions may have a material impact on the information set
forth in these materials. No representation is made that any performance or
return indicated herein will be achieved. For example, it is very unlikely that
the loans will prepay at a constant rate or follow a predictable pattern. This
information may not be used or otherwise disseminated in connection with the
offer or sale of these or any other securities, except in connection with the
initial offer or sale of these securities to you to the extent set forth below.
