the following:

PRELIMINARY STATEMENT:

                  The Depositor intends to sell pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple classes,
which in the aggregate will evidence the entire beneficial ownership interest in
each REMIC (as defined herein) created hereunder. The Trust Fund will consist of
a segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement.

                                     REMIC I
                                     -------

                  As provided herein, the Trustee will elect to treat the
segregated pool of assets consisting of the Mortgage Loans and certain other
related assets (other than any Master Servicer Prepayment Charge Payment Amounts
and the Net WAC Rate Carryover Reserve Account) subject to this Agreement as a
REMIC for federal income tax purposes, and such segregated pool of assets will
be designated as "REMIC I." The Class R-I Interest will be the sole class of
"residual interests" in REMIC I for purposes of the REMIC Provisions (as defined
herein). The following table irrevocably sets forth the designation, the REMIC I
Remittance Rate, the initial Uncertificated Balance and, solely for purposes of
satisfying Treasury regulation section 1.860G-1(a)(4)(iii), the "latest possible
maturity date" for each of the REMIC I Regular Interests (as defined herein).
None of the REMIC I Regular Interests will be certificated.
