DBRS rates four groups in this resecuritization trust, each consisting of one seasoned senior residential mortgage-backed security (RMBS). The ratings on the certificates reflect the credit enhancement provided by subordination within their respective groups. The ratings also reflect the quality of the underlying assets. Initial Exchangeable Certificates are exchangeable for Subsequent Exchangeable Certificates and vice versa in the combinations described in the private placement memorandum.

Other than the specified classes above, DBRS does not rate any other certificates in this transaction.

Interest and principal payments on the certificates will be made on the same day as the underlying distribution date (the 25th of each month), commencing in May 2010. Interest payments will be distributed on a pro rata basis to the certificates within their respective groups. Principal will be distributed on a sequential basis to the certificates within their respective groups until the certificate principal balances thereof are reduced to zero.

Any losses realized from the underlying securities will be allocated in a reverse sequential order to the certificates within their respective groups.

The DBRS-rated groups within the Trust are resecuritizations of four senior RMBS, represented by four real estate mortgage investment conduits (REMICs). The REMICs are backed by pools of prime or Alt-A, fixed- or adjustable-rate, first-lien, one- to four-family residential mortgages.
