The Offered Certificates were issued pursuant to a Pooling and Servicing Agreement, dated November 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.

As of the date of initial issuance, the Offered Certificates evidenced an approximate 99.30% undivided interest in a trust (the "Trust"), consisting principally of four pools of adjustable interest rate, 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.

Elections will be made to treat the Trust as two separate REMICs for federal income tax purposes (the "Upper-Tier REMIC" and the "Lower-Tier REMIC" and each a "REMIC"). The Class 1-A-1, Class 1-A-2, Class 2-A-1, Class 2-A-2, Class 3-A-1, Class 3-A-2, Class 3-A-3, Class 4-A-1, Class 1-IO, Class 2-IO, Class 4-IO, Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates will be treated as "regular interests" in the REMIC and the Class 1-A-R and Class 1-A-LR Certificates will be treated as the "residual interest" in the Upper-Tier REMIC and the Lower-Tier REMIC, respectively.
