STATEMENT REGARDING ASSUMPTIONS AS TO SECURITIES, PRICING ESTIMATES AND OTHER INFORMATION

The attached information contains certain tables and other statistical analyses (the “Computational Materials”) which have been prepared in reliance upon information furnished by the Mortgage Loan Sellers. Numerous assumptions were used in preparing the Computational Materials, which may or may not be reflected herein. As such, no assurance can be given as to the Computational Materials’ accuracy, appropriateness or completeness in any particular context; or as to whether the Computational Materials and/or the assumptions upon which they are based reflect present market conditions or future market performance. The 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.  None of BMO Capital Markets Corp., KeyBanc Capital Markets Inc., Deutsche Bank Securities Inc., Nomura Securities International, Inc., Wells Fargo Securities, LLC, SG Americas Securities, LLC, Citigroup Global Markets Inc., J.P. Morgan Securities LLC, UBS Securities LLC, LLC, Academy Securities, Inc., Bancroft Capital, LLC, Drexel Hamilton, LLC, Mischler Financial Group, Inc., Natixis Securities Americas LLC, or any of their respective affiliates, make 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 information in this presentation is based upon management forecasts and reflects prevailing conditions and management’s views as of this date, all of which are subject to change. In preparing this presentation, we have relied upon and assumed, without independent verification, the accuracy and completeness of all information available from public sources or which was provided to us by or on behalf of the Mortgage Loan Sellers or which was otherwise reviewed by us.
