     form of Prospectus included in CMSI's Registration Statement(333-109722).

2    Such percentages are expressed as a percentage of the aggregate scheduled
     principal balance of the pool I mortgage loans having such characteristics
     relative to the aggregate scheduled principal balance of all the pool I
     mortgage loans, as a percentage of the aggregate scheduled principal
     balance of the pool II mortgage loans having such characteristics relative

          value of the pledged additional collateral, are 80.0% and 73.5%,
          respectively; and

     4.   the weighted average loan-to-value ratios of such pool I mortgage
          loans and pool III mortgage loans, without taking into account the
