Business Editors

NEW YORK--(BUSINESS WIRE)--Aug. 28, 2003

ABN AMRO Mortgage Corporation's (AMAC) multi-class mortgage pass-through certificates, series 2003-10, are rated by Fitch Ratings as follows:

-- $198,949,651 classes A-1, A-2, A-P, A-X and R 'AAA';

-- $1,208,808 class M 'AA';

-- $402,936 class B-1 'A';

-- $302,202 class B-2 'BBB';

-- $201,468 class B-3 'BB';

-- $201,468 class B-4 'B'.

The 'AAA' rating on the class A senior certificates reflects the 1.25% subordination provided by the 0.60% class M, 0.20% class B-1, 0.15% class B-2, 0.10% privately offered class B-3, 0.10% privately offered class B-4 and 0.10% privately offered class B-5.

Fitch believes the amount of credit enhancement will be sufficient to cover credit losses, including limited bankruptcy, fraud and special hazard losses. The ratings also reflect the high quality of the underlying collateral originated by ABN AMRO Mortgage Group, Inc. (AAMG), the integrity of the legal and financial structures and the servicing capabilities of AAMG (rated 'RPS2+' by Fitch).

The mortgage pool consists of one group of recently originated, 15-year fixed-rate mortgage loans secured by one- to four-family residential properties. The mortgage loans have an aggregate principal balance of $201.4 million as of Aug. 1, 2003, (the cut-off date) and a weighted average remaining term to maturity of 178 months. The weighted average original loan-to-value ratio (OLTV) of the pool is approximately 58.46%; approximately 0.89% of the mortgage loans have an OLTV greater than 80%. The weighted average coupon of the mortgage loans is 4.988%. The weighted average FICO score is 745. The states that represent the largest geographic concentration are California (38.40%) and Illinois (5.16%). All other states represent less than 5% of the outstanding balance of the pool.

None of the mortgage loans are "high cost" loans as defined under any local, state or federal laws.

AAMG originated all of the loans. JPMorgan Chase Bank will serve as trustee. AMAC, a special purpose corporation, deposited the loans in the trust, which issued the certificates, representing undivided beneficial ownership in the trust. For federal income tax purposes, election will be made to treat the trust as a real estate mortgage investment conduit (REMIC).
