CORPORATION,   as master   servicer   (together   with its permitted   successors and

(together with its permitted successors and assigns, the "Trustee").

 

                             PRELIMINARY STATEMENT:

 

        The   Depositor   intends   to   sell   mortgage   asset-backed    pass-through

certificates   (collectively,   the   "Certificates"),   to be issued   hereunder   in

eighteen   Classes,   which in the aggregate   will evidence the entire   beneficial

ownership   interest in the Mortgage Loans (as defined   herein) and certain other

related assets.

 

                                     REMIC I

 

        As provided   herein,   the REMIC   Administrator   will make an election to

treat the segregated pool of assets consisting of the Mortgage Loans and certain

other related assets (exclusive of the Yield Maintenance   Agreement)   subject to

this   Agreement   as a real estate   mortgage   investment   conduit (a "REMIC") for

federal   income   tax   purposes,   and   such   segregated   pool of   assets   will be

designated   as "REMIC I." The Class R-I   Certificates   will   represent   the sole

Class of "residual   interests"   in REMIC I for purposes of the REMIC   Provisions

(as   defined    herein)   under   federal   income   tax   law.   The   following   table

irrevocably   sets forth the   designation,   remittance rate (the   "Uncertificated

REMIC I Pass-Through   Rate") and initial   Uncertificated   Principal   Balance for

each of the "regular   interests"   in REMIC I (the "REMIC I Regular   Interests").

    Interests related to such Certificates.

(3) The   Class   A-I,   Class   A-II,   Class M and Class B   Certificates   will also

    entitle   their   holders to certain   payments from the Holder of the Class SB

    Certificates from amounts to which the related REMIC III Regular Interest is

    Certificates   will be   comprised   of two   REMIC   III   Regular   Interests,   a

    principal only regular interest   designated REMIC III Regular Interest SB-PO

    and an interest only regular interest   designated REMIC III Regular Interest

    SB-IO,   which will be entitled to   distributions   as set forth   herein.   The
