Class 15-B-1, Class 15-B-2 and Class 15-B-3 (the "Offered Certificates"), having
an aggregate original principal balance of $917,806,375.00. The Offered
Certificates were issued pursuant to a Pooling and Servicing Agreement, dated
July 29, 2004, among the Registrant, Bank of America, N.A., as servicer ("BANA")
and Wells Fargo Bank, N.A., as trustee (the "Agreement"), a copy of which is
filed as an exhibit hereto. Mortgage Pass-Through Certificates, Series 2004-7,

initial principal balance of $4,090,567 (the "Private Certificates" and,
together with the Offered Certificates, the "Certificates"), were also issued
pursuant to the Agreement.

As of the date of initial issuance, the Offered Certificates evidenced an
approximate 99.55% undivided interest in a trust (the "Trust"), consisting
principally of four pools of fixed interest rate, conventional, monthly pay,
fully-amortizing, one- to four-family residential first mortgage loans. The
remaining undivided interests in the Trust are evidenced by the Private
Certificates.

Interest on the Offered Certificates will be distributed on each Distribution
Date (as defined in the Agreement). Monthly distributions in reduction of the
principal balance of the Offered Certificates will be allocated to the Offered
Certificates in accordance with the priorities set forth in the Agreement.
Distributions of interest and in reduction of principal balance on any
Distribution Date will be made to the extent that the related Pool Distribution
Amount or Amounts is sufficient therefor.

Elections will be made to treat the Trust as three separate REMICs for federal
income tax purposes (the "Upper-Tier REMIC," the "Middle-Tier REMIC" and the
"Lower-Tier REMIC" and each a "REMIC"). The Class 1-A-1, Class 1-A-2, Class
