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
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 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 mortgage loans to the company on the Closing
Date pursuant to the Mortgage Loan Purchase Agreement and the company conveyed
the mortgage loans to the trust on the Closing Date pursuant to the Agreement.
The Seller made certain representations and warranties with respect to the
mortgage loans in the Mortgage Loan Purchase Agreement. These representations
and warranties were assigned by the company to the Trustee for the benefit of
the Certificateholders. 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. 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.

PREPAYMENT CHARGES

         Approximately 72.11% of the mortgage loans in Loan Group 1 and 67.74%
of the 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


                                        7


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 mortgage loans range from .330% to 2.220% of the Stated Principal Balance of
the related Radian PMI Insured Loan and the Radian PMI Rates for the mortgage
loans have a weighted average of approximately 1.127%.

         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.

         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 3,781 mortgage loans, 1,240 of which
are in Loan Group 1 and 2,541 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 $475,031,765, 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 $383,682. No Group 1 Loan had a principal balance at origination
of greater than approximately $1,850,000 or less than approximately $50,400. The
average principal balance of the Group 1 Loans as of the Cut-off Date was
approximately $383,090. No Group 1 Loan had a principal balance as of the
Cut-off Date of greater than approximately $1,850,000 or less than approximately
$50,362.

         As of the Cut-off Date, the Group 1 Loans had mortgage rates ranging
from approximately 3.500% per annum to approximately 10.500% per annum and the
weighted average mortgage rate was approximately 5.724% per annum. The weighted
average remaining term to stated maturity of the Group 1 Loans was approximately
358 months as of the Cut-off Date. None of the Group 1 Loans will have a first
Due Date prior to April 1, 2004, or after February 1, 2005, or will have a
remaining term to maturity of less than 350 months or greater than 360 months as
of the Cut-off Date. The latest maturity date of any Group 1 Loan is January 1,
2035.

         Approximately .10%, 74.32% and 10.22% of the Group 1 Loans have initial
interest only periods of three, five 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 75.56%. No loan-to-value ratio at origination of any Group 1 Loan
was greater than approximately 100.00% or less than approximately 25.00%.

                                       8


         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 72.11% of the Group 1 Loans provide for prepayment
charges.

         Approximately 1.53% and 9.58% 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
1.140% 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)   A mortgage loan with a loan program including the term "30Y LIBOR 1MO" has
      a term of 30 years and the mortgage rate adjusts monthly based on the
      value of One-Month LIBOR. A mortgage loan with a loan program including
      the term "30Y LIBOR 6MO" has a term of 30 years and the mortgage rate
      adjusts semi-annually based on the value of Six-Month LIBOR. A mortgage
      loan with a loan program including the term "30Y LIBOR 12MO" has a term of
      30 years and the mortgage rate adjusts annually based on the value of
      One-Year LIBOR. A mortgage loan with a loan program including the term
      "2/28 LIBOR 6MO" has a term of 30 years, the first two of which consist of
      a fixed rate period, and thereafter the mortgage rate adjusts
      semi-annually based on the value of Six-Month LIBOR. A mortgage loan with
      a loan program including the term "3/27 LIBOR 6MO" has a term of 30 years,
      the first three of which consist of a fixed rate period, and thereafter
      the mortgage rate adjusts semi-annually based on the value of Six-Month
      LIBOR. A mortgage loan with a loan program including the term "5/25 LIBOR
      6MO" has a term of 30 years, the first five of which consist of a fixed
      rate period, and thereafter the mortgage rate adjusts semi-annually based
      on the value of Six-Month LIBOR. A mortgage loan with a loan program
      including the term "7/23 LIBOR 6MO" has a term of 30 years, the first
      seven of which consist of a fixed rate period, and thereafter the mortgage
      rate adjusts semi-annually based on the value of Six-Month LIBOR . Any
      mortgage loan with a loan program including the term "IO" has an interest
      only period.

(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-, C and CX correspond to Progressive Series I+, I and II, III and
III+, 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.

         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 $524,999,478, 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 $206,818. No Group 2 Loan had a principal balance at origination
of greater than approximately $637,000 or less than approximately $50,000. The
average principal balance of the Group 2 Loans as of the Cut-off Date


                                       25



was
approximately $206,611. No Group 2 Loan had a principal balance as of the
Cut-off Date of greater than approximately $637,000 or less than approximately
$30,400.

         As of the Cut-off Date, the Group 2 Loans had mortgage rates ranging
from approximately 3.500% per annum to approximately 10.250% per annum and the
weighted average mortgage rate was approximately 5.842% per annum. The weighted
average remaining term to stated maturity of the Group 2 Loans was approximately
358 months as of the Cut-off Date. None of the Group 2 Loans will have a first
Due Date prior to January 1, 2004, or after February 1, 2005, or will have a
remaining term to maturity of less than 347 months or greater than 360 months as
of the Cut-off Date. The latest maturity date of any Group 2 Loan is January 1,
2035.

         Approximately 0.01%, 0.21%, 73.15% and 5.80 of the Group 2 Loans have
initial interest only periods of two, three, five 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 76.09%. No loan-to-value ratio at origination of any Group 2 Loan
was greater than approximately 100.00% or less than approximately 16.67%.

         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 67.74% of the Group 2 Loans provide for prepayment
charges.

         Approximately 2.02% and 6.65% 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
1.109% 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-, B, 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
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.
