employment (or in the case of self-employed mortgagors or mortgagors
relying on commission income, fluctuations in income), marital separation
and a mortgagor's equity in the related mortgaged property. In addition,
delinquency and foreclosure experience may be sensitive to adverse economic
conditions, either nationally or regionally, may exhibit seasonal
variations and may be influenced by the level of interest rates and
servicing decisions on the applicable mortgage loans. Regional economic
conditions (including declining real estate values) may particularly affect
delinquency and foreclosure experience on mortgage loans to the extent that
mortgaged properties are concentrated in certain geographic areas.
DESCRIPTION OF THE CERTIFICATES
General
The Trustee will issue the certificates pursuant to a Pooling and
Servicing Agreement to be dated as of the Cut-Off Date among ABN AMRO
Mortgage Corporation, as Depositor, LaSalle Home Mortgage Corporation, as
Servicer, and Chase Bank of Texas, National Association, as Trustee, a form
of which is filed as an exhibit to the registration statement of which this
prospectus supplement is a part. Reference is made to the prospectus for
important additional information regarding the terms and conditions of the
Pooling and Servicing Agreement and the certificates. It is a condition to
the issuance of the offered certificates that they receive the ratings from
one or more of Standard & Poor's, a division of the McGraw Hill Companies,
Inc. ("S&P") and Fitch IBCA, Inc. ("Fitch") indicated under "Certificate
Ratings". As of the date of their issuance, the offered certificates, other
than the Class B-1 and Class B-2 certificates, will qualify as "mortgage
related securities" within the meaning of the Secondary Mortgage Market
Enhancement Act of 1984.
The Servicer will be obligated to make advances with respect to
delinquent payments on the Loans as described under "Advances".
The certificates, other than the Class R certificate, will
evidence all the beneficial ownership in a trust called REMIC II
established by the Depositor to hold the regular interests of REMIC I into
which the mortgage loans will be deposited.
Only the Senior certificates and Senior Subordinate certificates
are offered hereby. The Junior Subordinate certificates are not offered
hereby. The class principal balance for any class of certificates or
component principal balance for any component of the Class A-5 certificates
will equal the aggregate amount of principal to which such class or
component is entitled, after giving effect to prior (1) distributions of
principal to such class or component, (2) adjustments for accrued interest
added to principal on the Accrual certificate and component and (3)
allocations of losses required to be borne by such class or component.
Notwithstanding the foregoing, the class principal balance of the most
subordinate class of certificates outstanding at any time is equal to the
aggregate scheduled principal balance of all of the Loans less the class
principal balance of all other classes of certificates. As used in this
prospectus supplement, the principal balance of a class means the class
principal balance thereof and the component principal balance of a
component means the component principal balance thereof.
<PAGE>
The certificate principal balance for any certificate will be the
portion of the corresponding class principal balance represented by such
certificate. The aggregate initial certificate principal balance will be
approximately equal to the aggregate principal balance of the Loans as of
the Cut-Off Date. The offered certificates (other than the Class A-8 and
Class A-9 certificates and the Class R certificate) are offered in minimum
denominations equivalent to at least $25,000 initial certificate principal
balance each and multiples of $1 in excess thereof. The Class A-8 and Class
A-9 certificates are offered in minimum denominations equivalent to at
least $1,000 initial certificate principal balance each and multiples of
$1,000 in excess thereof. The Class R certificate will be offered in
registered, certificated form in a single denomination of a 100% percentage
interest. Holders of the Class A-5 certificates may not transfer the
components thereof separately.
