The attached information contains certain tables and other statistical analyses (the “Computational Materials”) which have been prepared in reliance upon information furnished by the depositor. These materials are subject to change, completion or amendment from time to time. Numerous assumptions were used in preparing the Computational Materials, which may or may not be reflected herein. These Computational Materials should not be construed as either projections or predictions or as legal, tax, financial or accounting advice. You should consult your own counsel, accountant and other advisors as to the legal, tax, business, financial and related aspects of a purchase of these securities. Any weighted average lives, yields and principal payment periods shown in the Computational Materials are based on prepayment and/or loss assumptions, and changes in such prepayment and/or loss assumptions may dramatically affect such weighted average lives, yields and principal payment periods. In addition, it is possible that prepayments or losses on the underlying assets will occur at rates higher or lower than the rates shown in the attached Computational Materials. The specific characteristics of the securities may differ from those shown in the Computational Materials due to differences between the final underlying assets and the preliminary underlying assets used in preparing the Computational Materials. The principal amount and designation of any security described in the Computational Materials are subject to change prior to issuance. Neither JPMorgan nor any of its affiliates makes any representation or warranty as to the actual rate or timing of payments or losses on any of the underlying assets or the payments or yield on the securities.

The “Certificate Principal to Value Ratio” for any Class (other than the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5 and Class A-SB Certificates) is calculated as the product of (a) the weighted average Cut-off Date LTV Ratio for the mortgage loans, multiplied by (b) a fraction, the numerator of which is the total initial Certificate Balance of such Class of Certificates and all Classes of Principal Balance Certificates senior to such Class of Certificates and the denominator of which is the total initial Certificate Balance of all of the Principal Balance Certificates. The Class A-1, Class A-2, Class A-3, Class A-4, Class A-5 and Class A-SB Certificate Principal to Value Ratios are calculated in the aggregate for those Classes as if they were a single Class. Investors should note, however, that excess from any mortgage loan will not be available to offset losses on any other mortgage loan.
