This resecuritization trust consists of 47 underlying seasoned senior residential mortgage-backed securities (RMBS). The AAA (sf) rating on the Class A-1 Notes reflects the 63% credit enhancement provided by subordination. The AA (sf) and A (sf) ratings reflect 57% and 52% of credit enhancement, respectively. The ratings also reflect the quality of the underlying assets.

The rating assigned to the securities address (i) the likelihood of the receipt by security holders of all principal distributions to which such security holders are entitled and (ii) the likelihood of the receipt by security holders of the amount of interest actually received by the Trust in respect of the underlying securities (as such interest entitlement may be reduced in accordance with the underlying agreement) to the extent payable to such class in accordance with the priorities described in the operative documents.

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

Interest and principal payments on the securities will generally be made two business days following the latest underlying distribution date (the 27th of the month), commencing in June 2011. Interest will be distributed on a sequential 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 securities will be allocated in a reverse sequential order to the notes.

This resecuritization is backed by 47 seasoned senior RMBS, represented by 43 real estate mortgage investment conduits (REMICs). The REMICs are backed by pools of prime and Alt-A, fixed- and adjustable-rate, first-lien, one- to four-family residential mortgages.
