Price/Yield Tables

         The tables set forth hereafter show the corporate bond equivalent
yield, modified duration, weighted average life, principal window, the first
principal Distribution Date, as well as the final Distribution Date on which
principal or interest, as applicable, is to be paid with respect to the Classes
of Offered Certificates under various scenarios (all prepayment speeds being
inclusive of repurchase of any Mortgage Loans due to conversion) and for a
variety of purchase prices. Purchase prices are generally expressed in 32nds
(i.e. 9-12 means 9-12/32) as a percentage of the related aggregate principal
balance (the "Certificate Balance") of the relevant Class.
         The yields set forth in the following tables were calculated by
determining the monthly discount rates which, when applied to the assumed stream
of cash flows to be paid on each Class of Offered Certificates, would cause the
discounted present value of such assumed stream of cash flows to equal the
assumed purchase prices, plus accrued interest at the applicable pass-through
rate from and including the Cut-Off Date but excluding the Delivery Date, and
converting such monthly rates to semi-annual corporate bond equivalent rates.
Assumed cash flows were determined based on actual loan terms, and the
assumptions as to prepayments, set forth on the following page, and to the
extent not inconsistent herewith, based on the Maturity Assumptions as defined
in the Preliminary Prospectus Supplement dated May 10, 1999 with respect to the
Offered Certificates. Such calculation does not take into account variations
that may occur in the interest rates at which investors may be able to reinvest
funds received by them as reductions of the Certificate Balances of the
respective Classes of Offered Certificates and consequently does not purport to
reflect the return on any investment in such Classes of Certificates when such
reinvestment rates are considered. For purposes of these tables, "modified
duration" has been calculated using Macaulay Duration. The Macaulay Duration is
calculated as the present value weighted average time to receive future payments
of principal and interest. Modified duration is calculated by dividing the
Macaulay Duration by the appropriate semi-annual compounding factor. The
duration of a security may be calculated according to various methodologies;
accordingly, no representation is made by the Depositor, the Underwriters or any
other person that the "modified duration" approach used herein is appropriate.
Duration, like yield, will be affected by the prepayment rate of the Mortgage
Loans and extensions in respect of Balloon Payments that actually occur during
the life of the Offered Certificates and by the actual performance of the
Mortgage Loans, all of which may differ, and may differ significantly, from the
assumptions used in preparing the tables below. The modified duration shown in
the following tables, in each case, relates to the yield shown immediately above
such modified duration number.
