hereby amended to add the clauses (65), (66), (67), (68) and (69) after clause
(64):

               "(65) Origination Practices/No Steering. No Mortgagor was
encouraged or required to select a Mortgage Loan product offered by the Mortgage
Loan's originator which is a higher cost product designed for less creditworthy
borrowers, unless at the time of the Mortgage Loan's origination, such Mortgagor
did not qualify taking into account credit history and debt-to-income ratios for
a lower-cost credit product then offered by the Mortgage Loan's originator or
any affiliate of the Mortgage Loan's originator. If, at the time of loan
application, the Mortgagor may have qualified for a lower-cost credit product
then offered by any mortgage lending affiliate of the Mortgage Loan's
originator, the Mortgage Loan's originator referred the Mortgagor's application
to such affiliate for underwriting consideration;

               (66) Underwriting Methodology. The methodology used in
underwriting the extension of credit for each Mortgage Loan does not rely solely
on the extent of the Mortgagor's


                                      -7-
<PAGE>

equity in the collateral as the principal determining factor in approving such
extension of credit. The methodology employed objective criteria such as the
Mortgagor's income, assets and liabilities, to the proposed mortgage payment
and, based on such methodology, the Mortgage Loan's originator made a reasonable
determination that at the time of origination the Mortgagor had the ability to
make timely payments on the Mortgage Loan. Such underwriting methodology
confirmed that at the time of origination (application/approval) the Mortgagor
had a reasonable ability to make timely payments on the Mortgage Loan;

               (67) Points and Fees. No Mortgagor was charged "points and fees"
(whether or not financed) in an amount greater than (i) $1,000, or (ii) 5% of
the principal amount of such Mortgage Loan, whichever is greater. For purposes
of this representation, such 5% limitation is calculated in accordance with
Fannie Mae's anti-predatory lending requirements as set forth in the Fannie Mae
Guides and "points and fees" (x) include origination, underwriting, broker and
finder fees and charges that the mortgagee imposed as a condition of making the
Mortgage Loan, whether they are paid to the mortgagee or a third party; and (y)
exclude bona fide discount points, fees paid for actual services rendered in
connection with the origination of the Mortgage Loan (such as attorneys' fees,
notaries fees and fees paid for property appraisals, credit reports, surveys,
title examinations and extracts, flood and tax certifications, and home
inspections), the cost of mortgage insurance or credit-risk price adjustments,
the costs of title, hazard, and flood insurance policies, state and local
transfer taxes or fees, escrow deposits for the future payment of taxes and
insurance premiums, and other miscellaneous fees and charges which miscellaneous
fees and charges, in total, do not exceed 0.25% of the principal amount of such
Mortgage Loan;

               (68) Fees Charges. All fees and charges (including finance
charges) and whether or not financed, assessed, collected or to be collected in
connection with the origination and servicing of each Mortgage Loan has been
disclosed in writing to the Mortgagor in accordance with applicable state and
federal law and regulation; and

               (69) Second Lien Mortgage Loans. With respect to each Second Lien
Mortgage Loan: (1) the related First Lien Mortgage Loan does not permit negative
amortization; (2) where required or customary in the jurisdiction in which the
Mortgaged Property is located, the original lender has filed for record a
request for notice of any action by the related senior lienholder, and the
Seller has notified such second lienholder in writing of the existence of the
Second Lien Loan and requested notification of any action to be taken against
the Mortgagor by such senior lienholder; either (a) no consent for the Second
Lien Mortgage Loan is required by the holder of the related First Lien Loan or
(b) such consent has been obtained and is contained in the related Mortgage
File; (3) to the best of Seller's knowledge, the related First Lien Loan is in
full force and effect, and there is no default, lien, breach, violation or event
which would permit acceleration existing under such First Lien Loan or Mortgage
Note, and no event which, with the passage of time or with notice and the
expiration of any grace or cure period, would constitute a default, breach,
violation or event which would permit acceleration under such First Lien Loan;
(4) the related first lien Mortgage contains a provision which provides for
giving notice of default or breach to the Mortgagee under the Mortgage Loan and
allows such Mortgagee to cure any default under the related First Lien Mortgage;
and (5) the related Mortgaged Property was the Mortgagor's principal residence
at the time of the origination of such Second Lien Loan."
