The Underlying Certificates (Groups 2, 3, 4 and 10) The Group 2, 3, 4 and 10 Trust Assets are Underlying Certificates that represent beneficial ownership interests in separate trusts, the assets of which evidence direct or indirect beneficial ownership interests in certain Ginnie Mae Certificates. Each Underlying Certificate constitutes all or a portion of a class of a separate Series of certificates described in the related Underlying Certificate Disclosure Documents, excerpts of which are attached as Exhibit B to this Supple- ment. Each Underlying Certificate Disclosure Document may be obtained from the Information Agent as described under "Available Information" in this Supplement. Investors are cautioned that material changes in facts and circumstances may have occurred since the date of each Underlying Certificate Disclosure Document, including changes in prepayment rates, prevail- ing interest rates and other economic factors, which may limit the usefulness of, and be directly contrary  to  the  assumptions  used  in  preparing  the  information  included  in,  the  offering document. See "Underlying Certificates" in the Base Offering Circular. Each Underlying Certificate provides for monthly distributions and is further described in the table contained in Exhibit A to this Supplement. The table also sets forth information regarding approximate weighted average remaining terms to maturity, loan ages and mortgage rates of the Mortgage Loans underlying the related Ginnie Mae Certificates. The Mortgage Loans The Mortgage Loans underlying the Group 1, 5, 6, 7, 8 and 9 Trust Assets are expected to have,  on  a  weighted  average  basis,  the  characteristics  set  forth  in  the  Terms  Sheet  under "Assumed Characteristics of the Mortgage Loans Underlying the Group 1, 5, 6, 7, 8 and 9 Trust Assets" and the general characteristics described in the Base Offering Circular. The Mortgage Loans underlying the Underlying Certificates are expected to have, on a weighted average basis, the characteristics set forth in Exhibit A to this Supplement. The Mortgage Loans will consist of first lien, single-family, fixed rate, residential mortgage loans that are insured or guaranteed by the Federal Housing Administration, the United States Department of Veterans Affairs, the Rural Housing  Service  or  the  United  States  Department  of  Housing  and  Urban  Development ("HUD"). See "The Ginnie Mae Certificates – General" in the Base Offering Circular. Specific information regarding the characteristics of the Mortgage Loans is not available. For purposes of this Supplement, certain assumptions have been made regarding the remaining terms to maturity, loan ages and, in the case of the Group 1, 7 and 9  Trust Assets,  Mortgage Rates of the Mortgage Loans. However, the actual remaining terms to maturity, loan ages and, in the case of the Group 1, 7 and 9 Trust Assets, Mortgage Rates of many of the Mortgage Loans will differ from the characteristics assumed, perhaps significantly. This will be the case even if the  weighted  average  characteristics  of  the  Mortgage  Loans  are  the  same  as  the  assumed characteristics.  Small  differences  in  the  characteristics  of  the  Mortgage  Loans  can  have  a significant effect on the weighted average lives and yields of the Securities. See "Risk Factors" and "Yield, Maturity and Prepayment Considerations" in this Supplement. The Trustee Fee On each Distribution Date, the Trustee will retain a fixed percentage of all principal and interest distributions received on specified Trust Assets in payment of its fee.
