There are seven groups total in this resecuritization trust. DBRS rates notes from groups 5, 6 and 7. Each DBRS-rated group consists of one seasoned senior residential mortgage-backed security (RMBS). The ratings on the offered notes reflect the credit enhancement provided by subordination and the quality of the underlying asset. The Exchangeable REMIC Notes are exchangeable for the Exchangeable Notes and vice versa, in the related combinations described in the private placement memorandum.

The rating assigned to the respective offered securities addresses (i) the likelihood of the receipt by noteholders of all principal distributions to which such noteholders are entitled and (ii) the likelihood of the receipt by noteholders of the amount of interest actually received by the trust to the extent payable to each class in accordance with the priorities described in the operative documents (as such interest received by the trust may have been reduced as a result of any interest shortfalls allocated to the related underlying securities, and as such interest entitlement may be further reduced by the allocation of extraordinary trust expenses). For more details on the ratings, please refer to the offering documents.

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

Interest and principal payments on the securities will generally be made on the second business day following the underlying distribution date (the 25th of each month), commencing in December 2011.

Interest payments will be distributed on a pro rata basis to the securities. Principal will be distributed on a sequential basis to the securities, in the order of priority specified in the private placement memorandum, until the principal balances thereof are reduced to zero.

Any losses realized from the underlying security will be allocated in a reverse sequential order to the securities.

Each DBRS-rated group is a resecuritization of one seasoned senior RMBS, represented by one real estate mortgage investment conduit (REMIC). The REMICs are backed by pools of seasoned, fixed or adjustable-rate, first-lien, one- to four-family residential mortgages.
