      such
      losses, claims, damages or liabilities (or actions or demands for reimbursement
      or contribution in respect thereof) arise out of or are based upon information
      relating to the Seller or the mortgage loans pursuant to the Underwriting

    6. Purchase
      and Sale; Security Interest.
      The
      parties hereto intend the conveyance by the Seller to CMSI of all of its right,
      title and interest in and to the mortgage loans pursuant to this Agreement
      to
      constitute a purchase and sale and not a loan. Notwithstanding the foregoing,
      to
      the extent that such conveyance is held not to constitute a sale under
      applicable law, it is intended that this Agreement shall constitute a security
      agreement under applicable law and that the Seller shall be deemed to have
      granted to CMSI a first priority security interest in all of the Seller's right,
      title and interest in and to the mortgage loans.

      All
      demands, notices and communications hereunder shall be in writing, shall be

      representations and agreements made by the Seller in this Agreement are made
      for

      certificates, respectively, have rights against CMSI under the Pooling Agreement
      in respect of representations and agreements made by CMSI therein.

      waived, discharged or terminated except by a writing signed by the party against

      This Agreement may not be changed in any manner which would have a material
      adverse affect on holders of any class of certificates without the prior written
      consent of the Trustee. The Trustee shall be protected in consenting to any

      enforceable by CMSI and the Seller and their respective successors and assigns;
      provided,
      however,
      that
      this Agreement cannot be assigned by either party without the consent of the
      other party hereto, and any assignment hereof without such consent shall be
      void.
