-----------
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
     mortgage loans, as a percentage of the aggregate scheduled principal
     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.
At least 34%, 15% and 57%, respectively, of the pool I mortgage loans, the
pool II mortgage loans and the pool III mortgage loans, will be mortgage loans
originated using loan underwriting policies which require, among other things,
proof of income and liquid assets and telephone verification of employment. No
more than 44%, 61% and 2%, respectively, of the pool I mortgage loans, the pool
II mortgage loans and the pool III mortgage loans, were refinance transactions
originated using loan underwriting policies that require proof of income and
telephone verification of employment but do not require verification of assets.
No more than 4%, 6% and none, respectively, of the pool I mortgage loans, the
pool II mortgage loans and the pool III mortgage loans, were originated using a
loan underwriting policy that requires verification of employment and may
require proof of liquid assets, but does not require verification of the
prospective borrower's income as stated on the loan application. No more than
10%, 9% and 41%, respectively, of the pool I mortgage loans, the pool II
mortgage loans and the pool III mortgage loans, will be mortgage loans
originated using stated income loan underwriting policies that do not require
proof of the prospective borrowers income as stated on the loan application, do
not require proof of assets but do require telephone verification of employment.
No more than 8%, 9% and none, respectively, of the pool I mortgage loans, pool
II mortgage loans and the pool III mortgage loans, will be mortgage loans
originated using streamlined underwriting policies.

     All of the mortgage loans which had loan-to-value ratios greater than 80%
at origination had primary mortgage insurance as of such date. In the case of
the pool I mortgage loans for which additional collateral was pledged, taken as
a group:

      1.    the number of such mortgage loans is 4;

      2.    such mortgage loans had an aggregate scheduled principal balance of
            $2,280,273.66;

      3.    the weighted average loan-to-value ratio of such mortgage loans,
            taking into account the loanable value of the pledged additional
