1    Terms used herein and not defined have the meaning assigned thereto in the
     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

     balance of the pool II mortgage loans having such characteristics relative
     to the aggregate scheduled principal balance of all the pool II mortgage
     loans, or as a percentage of the aggregate scheduled principal balance of
     the pool III mortgage loans having such characteristics relative to the
     aggregate scheduled principal balance of all the pool III mortgage loans.
39.77%, 26.23% and 36.04%, respectively, of the pool I mortgage loans, the
