      made by wire transfer. Final distribution on the Certificates will be made
      only
      upon surrender of the Certificates at the offices of the Certificate Registrar
      set forth in the notice of such final distribution.

     

    The
      Certificates are issuable in fully registered form only, without coupons, in
      denominations specified in the Trust Agreement. As provided in the Trust

      Agreement, the transfer of this Certificate is registrable in the Certificate
      Register upon surrender of this Certificate for registration of transfer at

      and such other locations provided in the Trust Agreement, duly endorsed by

      more new Certificates of the same Class in the same aggregate Certificate
      Balance will be issued to the designated transferee or transferees.

     

    As
      provided in the Trust Agreement and subject to certain limitations therein
      set

      in the same denomination. No service charge will be made for any such
      registration of transfer or exchange, but the Custodian may require payment
      of a
      sum sufficient to cover any tax or other governmental charge that may be imposed
      in connection with any transfer or exchange of Certificates.

      obligations created by the Trust Agreement will terminate upon payment to the
      Certificateholders of all amounts held in the Collection Account and the
      Certificate Account required to be paid to the Certificateholders pursuant
      to
      the Trust Agreement, following the earlier of: (i) the final payment or other
      liquidation (or any advance with respect thereto) of the last Mortgage Loan
      remaining in the Trust Fund or the disposition of all property acquired upon
      foreclosure of any such Mortgage Loan and (ii) the purchase of all the assets
      of
      the Trust Fund by the Class C Certificateholder or the Master Servicer as
      specified in the Trust Agreement, when the aggregate Scheduled Principal Balance
      of the Mortgage Loans equals 1% or less of the aggregate Scheduled Principal
      Balance of the Mortgage Loans as of the Cut-off Date. Written notice of
      termination will be given to each Certificateholder, and the final distribution
      will be made only upon surrender and cancellation of the Certificates at an
      office or agency appointed by the Securities Administrator, which will be
      specified in the notice of termination.

     

    Unless

      Registrar, by manual signature, this Certificate shall not be entitled to any
      benefit under the Trust Agreement or be valid for any purpose.
