you may not be able to take advantage of higher yielding investment opportunities. The final payment on your security may occur much earlier than the final distribution date. Support securities will be more sensitive to rates of principal payments than other securities. If principal prepayments result in principal distributions on any distribution date equal to or less than the amount needed to produce scheduled payments on the PAC and  TAC classes, the related support classes will not receive any principal distribution on that date (other than from any applicable accrual amount). If prepayments result in principal distributions on any distribution date greater than the amount needed to produce scheduled payments on the related PAC  and  TAC classes for that distribution date, this excess will be distributed to the related support classes. The rate of principal payments on the underlying SMBS   securities   will directly affect the rate of principal payments on the group 1 securities.  The underlying SMBS securities will be sensitive to the rate of  payments  of  principal  (including prepayments) of the related mortgage loans. If prevailing interest rates are higher than the interest rates on the related mortgage loans, then borrowers will be less likely to make principal prepayments resulting in slower returns of principal payments on the group 1 securities. If prevailing interest rates are lower than the interest rates on the related mortgage loans, then the underlying SMBS securities   will   experience   significant principal prepayments resulting in faster prepayments than anticipated by investors in the group 1 securities. This supplement contains no information as to whether the underlying SMBS securities have performed as originally anticipated. Additional information as to the underlying SMBS  securities  may  be  obtained  by performing an analysis of current factors of the underlying SMBS securities in light of applicable information contained in the underlying SMBS security disclosure document. The securities may not be a suitable investment  for  you.  The  securities, especially the group 1 securities and, in particular, support,  interest only,  principal only,    inverse floating rate,    accrual    and residual classes, are not suitable investments for all investors. In addition, although the sponsor intends to make a market for the purchase and sale of the securities after their initial issuance, it has no obligation to do so. There is no assurance that a secondary market will develop, that any secondary market will continue, or that the price at which you can sell an investment in any class will enable you to realize a desired yield on that investment. You will bear the market risks of your investment. The market values of the classes are likely to fluctuate. These fluctuations may be significant and could result in significant losses to you. The secondary markets for mortgage-related securities have experienced periods of illiquidity and can be expected to do so in the future. Illiquidity can have a severely adverse effect on the prices of classes that are especially sensitive to prepayment or interest rate risk or that have been structured to meet the investment requirements of limited categories of investors. The residual securities may experience significant adverse tax timing consequences. Accordingly, you are urged to consult tax advisors and to consider the after-tax effect of ownership of a residual security and the suitability of the residual securities to your investment objectives. See "Certain Federal Income   Tax   Consequences"   in   this supplement and in the base offering circular. You are encouraged to consult advisors regarding the financial, legal, tax and other aspects of an investment in the securities. You should not purchase the securities of any class unless you understand and are able to bear the prepayment, yield, liquidity and market risks associated with that class. S-10
