THE MORTGAGE POOL

General

      References to percentages of the mortgage loans unless otherwise noted are
calculated based on the aggregate principal balance of the mortgage loans as of
the Cut-off Date, as applicable.

      The mortgage pool consists of two groups of mortgage loans, referred to in
this prospectus supplement as "Loan Group 1" and "Loan Group 2" (and each, a
"Loan Group"), and also designated as the "Group 1 Loans" and the "Group 2
Loans", respectively. The Group 1 Loans are one- to four-family,
adjustable-rate, fully-amortizing residential mortgage loans with non-conforming
loan balances secured by first liens on mortgaged properties. The Group 2 Loans
are one- to four-family, adjustable-rate, fully-amortizing residential mortgage
loans with conforming loan balances secured by first liens on mortgaged
properties. The mortgage loans will have original terms to maturity of not
greater than 30 years.

      The Group 1 Loans consist of mortgage loans which had principal balances
at origination which may or may not be greater than Fannie Mae or Freddie Mac
conforming balances and the Group 2 Loans consist of mortgage loans which had
principal balances at origination which are less than or equal to Fannie Mae or
Freddie Mac conforming balances. The conforming balance for mortgage loans
secured by a single family property is $333,700 for all mortgage loans other
than those originated in Alaska, Hawaii, Guam and the U.S. Virgin Islands, for
which it is $500,550. The conforming balance is higher for mortgage loans
secured by two- to four-family properties. Notwithstanding these conforming
balances, the Group 2 Loans have been originated according to underwriting
standards that do not satisfy Fannie Mae or Freddie Mac underwriting criteria.

      The Seller conveyed the initial mortgage loans to the company on the
Closing Date pursuant to the Mortgage Loan Purchase Agreement and the company
conveyed the initial mortgage loans to the trust on the Closing Date pursuant to
the Agreement. The company conveyed the Group 1 subsequent mortgage loans and
Group 2 subsequent mortgage loans to the trust during the Funding Period. The
Group 1 subsequent mortgage loans were acquired with amounts on deposit in the
Group 1 Pre-Funding Account pursuant to the Group 1 Subsequent Transfer
Instrument. The Group 2 subsequent mortgage loans were acquired with amounts on
deposit in the Group 2 Pre-Funding Account pursuant to the Group 2 Subsequent
Transfer Instrument. The Seller made certain representations and warranties with
respect to the initial mortgage loans in the Mortgage Loan Purchase Agreement
and with respect to the Group 1 subsequent mortgage loans and Group 2 subsequent
mortgage loans in the Group 1 subsequent mortgage loan purchase agreement and
Group 2 subsequent mortgage loan purchase agreement, respectively. These
representations and warranties were assigned by the company to the Trustee for
the benefit of the Certificateholders and the Certificate Insurer. As more
particularly described in the prospectus, the Seller has certain repurchase or
substitution obligations in connection with a breach of any such representation
or warranty, as well as in connection with an omission or defect in respect of
certain constituent documents required to be delivered with respect to the
mortgage loans, if such breach, omission or defect cannot be cured and it
materially and adversely affects the interests of the Certificateholders or the
Certificate Insurer. In the event the Seller fails to repurchase a mortgage
loan, Impac Holdings will be required to do so. See "The Mortgage
Pools--Representations by Sellers" in the prospectus.

      All of the mortgage loans have scheduled monthly payments due on the Due
Date. Each mortgage loan will contain a customary "due-on-sale" clause.


                                      99-1


Prepayment Charges

      Approximately 72.27% of the mortgage loans in Loan Group 1 and 73.51% of
the sample mortgage loans in Loan Group 2, provide for payment by the mortgagor
of a prepayment charge in limited circumstances on prepayments. Generally, these
mortgage loans provide for payment of a prepayment charge on partial or full
prepayments made within six months, one year, five years or other period as
provided in the related mortgage note from the date of origination of the
mortgage loan. The amount of the prepayment charge is as provided in the related
mortgage note, and the prepayment charge will generally apply if, in any
twelve-month period during the first year, five years or other period as
provided in the related mortgage note from the date of origination of the
mortgage loan, the mortgagor prepays an aggregate amount exceeding 20% of the
original principal balance of the mortgage loan. The amount of the prepayment
charge will generally be equal to 6 months' advance interest calculated on the
basis of the mortgage rate in effect at the time of the prepayment on the amount
prepaid in excess of 20% of the original principal balance of the mortgage loan.
The holders of the Class P Certificates will be entitled to all prepayment
charges received on the mortgage loans, and these amounts will not be available
for distribution on the other classes of certificates. The Master Servicer may
waive the collection of any otherwise applicable prepayment charge or reduce the
amount thereof actually collected, but only if the Master Servicer does so in
compliance with the prepayment charge waiver standards set forth in the
Agreement. If the Master Servicer waives any prepayment charge other than in
accordance with the standards set forth in the Agreement, the Master Servicer
will be required to pay the amount of the waived prepayment charge. There can be
no assurance that the prepayment charges will have any effect on the prepayment
performance of the mortgage loans.

Primary Mortgage Insurance and the Radian Lender-Paid PMI Policy

      Substantially all of the loans with a loan-to-value ratio at origination
in excess of 80.00% will be insured by one of the following: (1) a Primary
Insurance Policy issued by a private mortgage insurer (other than a Radian
Lender-Paid PMI Policy) or (2) a Radian Lender-Paid PMI Policy.

      Each Primary Insurance Policy will insure against default under each
insured mortgage note as follows: (A) for which the outstanding principal
balance at origination of such mortgage loan is greater than or equal to 80.01%
and up to and including 90.00% of the lesser of the Appraised Value and the
sales price, such mortgage loan is covered by a Primary Insurance Policy in an
amount equal to at least 12.00% of the Allowable Claim and (B) for which the
outstanding principal balance at origination of such mortgage loan exceeded
90.01% of the lesser of the Appraised Value and the sales price, such mortgage
loan is covered by a Primary Insurance Policy in an amount equal to at least
30.00% of the Allowable Claim.

      Each Radian Lender-Paid PMI Policy will insure against default under each
insured mortgage note as follows: (A) for which the outstanding principal
balance at origination of such mortgage loan is greater than or equal to 80.01%
and up to and including 95.00% of the lesser of the Appraised Value and the
sales price, such mortgage loan is covered by a Radian Lender-Paid PMI Policy in
an amount equal to at least 22.00% of the Allowable Claim and (B) for which the
outstanding principal balance at origination of such mortgage loan is at least
95.01% and up to and including 97.00% of the lesser of the Appraised Value and
the sales price, such mortgage loan is covered by such Radian Lender-Paid PMI
Policy in an amount equal to at least 35.00% of the Allowable Claim.

      With respect to the Radian Lender-Paid PMI Policies, the premium will be
payable by the Master Servicer out of interest collections on the mortgage loans
at a rate equal to the related Radian PMI Rate. The Radian PMI Rates for the
sample mortgage loans range from 19.21% to 11.10% of the Stated Principal


                                      99-2


Balance of the related Radian PMI Insured Loan and the Radian PMI Rates for the
sample mortgage loans have a weighted average of approximately 1.186%.

      To the extent of a default by Radian under the Radian Lender-Paid PMI
Policy, the Master Servicer will use its best efforts to find a replacement
policy with substantially similar terms, with the approval of the Certificate
Insurer.

      Each mortgage loan is required to be covered by a standard hazard
insurance policy.

      See "Primary Mortgage Insurance, Hazard Insurance; Claims
Thereunder--Hazard Insurance Policies" in the prospectus.

Mortgage Loan Characteristics

      The mortgage pool is comprised of 9,070 mortgage loans, 70.96% of which
are in Loan Group 1 and 29.04% of which are in Loan Group 2. References to
percentages of the mortgage loans unless otherwise noted are calculated based on
the aggregate principal balance of the mortgage loans as of the Cut-off Date.

      The original mortgages for some of the mortgage loans have been, or in the
future may be, at the sole discretion of the Master Servicer, recorded in the
name of Mortgage Electronic Registration Systems, Inc., or MERS, solely as
nominee for the Seller and its successors and assigns, and subsequent
assignments of those mortgages have been, or in the future may be, at the sole
discretion of the Master Servicer, registered electronically through the MERS(R)
System. In some other cases, the original mortgage was recorded in the name of
the originator of the mortgage loan, record ownership was later assigned to
MERS, solely as nominee for the owner of the mortgage loan, and subsequent
assignments of the mortgage were, or in the future may be, at the sole
discretion of the Master Servicer, registered electronically through the MERS(R)
System. For each of these mortgage loans, MERS serves as mortgagee of record on
the mortgage solely as a nominee in an administrative capacity on behalf of the
trustee, and does not have any interest in the mortgage loan. Some of the Group
1 Loans and Group 2 Loans were recorded in the name of MERS. For additional
information regarding the recording of mortgages in the name of MERS see "Yield
on the Certificates--Yield Sensitivity of the Mezzanine Certificates" in the
prospectus supplement.

Loan Group 1

      The Group 1 Loans had an aggregate principal balance as of the Cut-off
Date of approximately $1,632,079,834, after application of scheduled payments
due on or before the Cut-off Date, whether or not received. All of the Group 1
Loans are secured by first liens on the related mortgaged property.

      The average principal balance of the Group 1 Loans at origination was
approximately $274,137. No Group 1 Loan had a principal balance at origination
of greater than approximately $1,260,000 or less than approximately $22,050. The
average principal balance of the Group 1 Loans as of the Cut-off Date was
approximately $273,839. No Group 1 Loan had a principal balance as of the
Cut-off Date of greater than approximately $1,260,000 or less than approximately
$21,984.

      As of the Cut-off Date, the Group 1 Loans had mortgage rates ranging from
approximately 2.750% per annum to approximately 10.000% per annum and the
weighted average mortgage rate was approximately 5.586% per annum. The weighted
average remaining term to stated maturity of the Group 1 Loans was approximately
359 months as of the Cut-off Date. None of the Group 1 Loans will have a first
Due Date prior


                                      99-3


to September 1, 2003, or after November 1, 2004, or will have a remaining term
to maturity of less than 348 months or greater than 360 months as of the Cut-off
Date. The latest maturity date of any Group 1 Loan is October 1, 2034.

      Approximately0.03%, 3.31%, 0.60%, 48.41%, 0.12% and 5.34% of the Group 1
Loans have initial interest only periods of six months, two, three, five, seven
and ten years, respectively.

      The loan-to-value ratio of a mortgage loan secured by a first lien is
equal to the ratio, expressed as a percentage, of the principal amount of the
loan at origination, to the lesser of the appraised value of the related
mortgaged property at the time of origination and the sales price. The weighted
average of the loan-to-value ratios at origination of the Group 1 Loans was
approximately 79.71%. No loan-to-value ratio at origination of any Group 1 Loan
was greater than approximately 100.00% or less than approximately 12.90%.

      None of the Group 1 Loans are buydown mortgage loans.

      None of the Group 1 Loans will be subject to the Home Ownership and Equity
Protection Act of 1994 or any comparable state law.

      Substantially all of the Group 1 Loans will not have reached their first
adjustment date as of the Closing Date.

      Approximately 72.27% of the Group 1 Loans provide for prepayment charges.

      Approximately 18.20% and 11.69% of the Group 1 Loans are covered by a
Primary Insurance Policy and the Radian Lender-Paid PMI Policy, respectively.
For the Group 1 Loans, the weighted average of the Radian PMI Rates for the
mortgage loans covered by the Radian Lender-Paid PMI Policy is approximately
1.206% per annum.

      With respect to substantially all of the Group 1 Loans, the Minimum
Mortgage Rate is equal to the Gross Margin.

      Set forth below is a description of certain additional characteristics of
the Group 1 Loans as of the Cut-off Date, except as otherwise indicated. All
percentages of the Group 1 Loans are approximate percentages by aggregate
principal balance as of the Cut-off Date, except as otherwise indicated. Dollar
amounts and percentages may not add up to totals due to rounding.

(1) All of these Group 1 Loans were reviewed and placed into risk categories
based on the credit standards of the Progressive Series Program. Credit grades
of A+, A, A-, B, C and CX correspond to Progressive Series I+, I and II, III and
III+, IV, V and VI respectively.

(2) These Group 1 Loans were originated under the Seller's Progressive
Express(TM) Program. The underwriting for these Group 1 Loans is generally based
on the borrower's "Credit Score" score and therefore these Group 1 Loans do not
correspond to the alphabetical risk categories listed above. Each mortgage loan
originated pursuant to the Express Priority Refi(TM) Program has been placed in
either Progressive Express(TM) Program II or III.

      See "--Underwriting Standards" below for a description of the Seller's
risk categories.

      In general, in the case of a mortgage loan made for "rate and term"
refinance purposes, substantially all of the proceeds are used to pay in full
the principal balance of a previous mortgage loan of the mortgagor with respect
to a mortgaged property and to pay origination and closing costs associated with
such refinancing. Mortgage loans made for "cash-out" refinance purposes may
involve the use of the proceeds to pay in full the principal balance of a
previous mortgage loan and related costs except that a portion of the proceeds
are generally retained by the mortgagor for uses unrelated to the mortgaged
property. The amount of these proceeds retained by the mortgagor may be
substantial.

Loan Group 2

      The Group 2 Loans had an aggregate principal balance as of the Cut-off
Date of approximately $667,920,389, after application of scheduled payments due
on or before the Cut-off Date, whether or not received. All of the Group 2 Loans
are secured by first liens on the related mortgaged property.

      The average principal balance of the Group 2 Loans at origination was
approximately $215,038. No Group 2 Loan had a principal balance at origination
of greater than approximately $648,000 or less than approximately $30,150. The
average principal balance of the Group 2 Loans as of the Cut-off Date was


                                      99-20


approximately $214,765. No Group 2 Loan had a principal balance as of the
Cut-off Date of greater than approximately $647,442 or less than approximately
$30,026.

      As of the Cut-off Date, the Group 2 Loans had mortgage rates ranging from
approximately 3.000% per annum to approximately 9.990% per annum and the
weighted average mortgage rate was approximately 5.592% per annum. The weighted
average remaining term to stated maturity of the Group 2 Loans was approximately
359 months as of the Cut-off Date. None of the Group 2 Loans will have a first
Due Date prior to March 1, 2004, or after October 1, 2004, or will have a
remaining term to maturity of less than 354 months or greater than 360 months as
of the Cut-off Date. The latest maturity date of any Group 2 Loan is September
1, 2034.

      Approximately 2.75%, 0.48%, 42.56%, 0.08% and 2.28 of the Group 2 Loans
have initial interest only periods of two, three, five, seven and ten years,
respectively.

      The loan-to-value ratio of a mortgage loan secured by a first lien is
equal to the ratio, expressed as a percentage, of the principal amount of the
loan at origination, to the lesser of the appraised value of the related
mortgaged property at the time of origination and the sales price. The weighted
average of the loan-to-value ratios at origination of the Group 2 Loans was
approximately 80.44%. No loan-to-value ratio at origination of any Group 2 Loan
was greater than approximately 100.00% or less than approximately 20.22%.

      None of the Group 2 Loans are buydown mortgage loans.

      None of the Group 2 Loans will be subject to the Home Ownership and Equity
Protection Act of 1994 or any comparable state law.

      Substantially all of the Group 2 Loans will not have reached their first
adjustment date as of the Closing Date.

      Approximately 73.51% of the Group 2 Loans provide for prepayment charges.

      Approximately 21.66% and 9.66% of the Group 2 Loans are covered by a
Primary Insurance Policy and the Radian Lender-Paid PMI Policy, respectively.
For the Group 2 Loans, the weighted average of the Radian PMI Rates for the
mortgage loans covered by the Radian Lender-Paid PMI Policy is approximately
1.127% per annum.

      With respect to substantially all of the Group 2 Loans, the Minimum
Mortgage Rate is equal to the Gross Margin.

      Set forth below is a description of certain additional characteristics of
the Group 2 Loans as of the Cut-off Date, except as otherwise indicated. All
percentages of the Group 2 Loans are approximate percentages by aggregate
principal balance as of the Cut-off Date, except as otherwise indicated. Dollar
amounts and percentages may not add up to totals due to rounding.

(1) All of these Group 2 Loans were reviewed and placed into risk categories
based on the credit standards of the Progressive Series Program. Credit grades
of A+, A, A-, C and CX correspond to Progressive Series I+, I and II, III and
III+, V and VI, respectively.

(2) These Group 2 Loans were originated under the Seller's Progressive
Express(TM) Program. The underwriting for these Group 2 Loans is generally based
on the borrower's "Credit Score" score and therefore these Group 2 Loans do not
correspond to the alphabetical risk categories listed above. Each mortgage loan
originated pursuant to the Express Priority Refi(TM) Program has been placed in
either Progressive Express(TM) Program II or III.

      See "--Underwriting Standards" below for a description of the Seller's

      In general, in the case of a mortgage loan made for "rate and term"
refinance purposes, substantially all of the proceeds are used to pay in full
the principal balance of a previous mortgage loan of the mortgagor with respect
to a mortgaged property and to pay origination and closing costs associated with
such refinancing. Mortgage loans made for "cash-out" refinance purposes may
involve the use of the proceeds to pay in full the principal balance of a
previous mortgage loan and related costs except that a portion of the proceeds
are generally retained by the mortgagor for uses unrelated to the mortgaged
property. The amount of these proceeds retained by the mortgagor may be
substantial.
