Group II is comprised of approximately $[60,851,445] and consists of approximately [130] 3/1 and 3/6 hybrid mortgage loans that are secured by first liens on residential properties;

Group III is comprised of approximately $[179,385,276] and consists of approximately [846] 5/1 and 5/6 hybrid mortgage loans that have agency conforming balances secured by first liens on residential properties;

Group IV is comprised of approximately $[76,615,545] and consists of approximately [148] 5/1 and 5/6 hybrid mortgage loans that are secured by first liens on residential properties; and

Group VI is comprised of approximately $[37,806,993] and consists of approximately [71] 7/1 and 7/6 hybrid mortgage loans that are secured by first liens on residential properties.

Distributions of Offered Certificates:	On each monthly distribution date, the trustee will make distributions to investors. Except as provided in this prospectus supplement, the Class CB-I Certificates, which include the Class CB-I-1, Class CB-I-2 and the Class R Certificates will receive payments primarily from loan group I; the Class NB-I Certificates will receive payments primarily from loan group II; the Class CB-II-1 Certificates and the Class CB-II-2 will receive payments primarily from loan group III; the Class NB-II Certificates; the Class CB-III Certificates and Class NB-III Certificates, will receive payments primarily from loan groups IV, V and VI respectively. The Class M Certificates and Class B Certificates will receive payments from all six loan groups.
Principal and Interest Advancing:	For any month, if the Master Servicer receives a payment on a mortgage loan that is less than the full scheduled payment, or if no payment is received at all, the Master Servicer will advance its own funds to cover that shortfall. However, the Master Servicer will make an advance only if it determines that the advance will be recoverable from future payments or collections on that mortgage loan.
Compensating Interest:	For any Distribution Date, the Master Servicer will cover prepayment interest shortfalls up to an amount equal to the lesser of (a) one-twelfth of 0.125% of the aggregate principal balance of the mortgage loans immediately preceding that Distribution Date and (b) the sum of the master servicing fee payable to the Master Servicer in respect of its master servicing activities and reinvestment income received by the Master Servicer on amounts payable with respect to that Distribution Date with respect to the mortgage loans.

Allocation of Losses:	Realized Losses on the mortgage loans will be allocated first to the subordinate certificates in order of their reverse numerical class designation and second to the mezzanine certificates in order of their reverse numerical class designation until the certificate principal balance of each such Certificate has been reduced to zero. Thereafter Realized Losses on the mortgage loans will be allocated to proportionately among the senior certificates in accordance with their respective remaining certificate principal balances or accrued interest, subject to limitations. In addition, if the certificate principal balances of the subordinate and mezzanine Certificates have been reduced to zero, losses otherwise allocated to the Class CB-I-1 and Class CB-II-1 Certificates will be allocated to the Class CB-I-2 and CB-II-2 Certificates respectively, as long as the Class CB-I-2 and CB-II-2 Certificates respectively remain outstanding.
