| 1.   | ABN      AMRO Mortgage Group, Inc.

As set forth in Exhibit A hereto, the Servicer’s      management has determined that these Vendors are not considered a      “servicer” as defined in Item 1101(j) of Regulation AB, and the Servicer’s      management has elected to take responsibility for assessing compliance      with the servicing criteria applicable to each Vendor as permitted by      Interpretation 17.06 of the SEC Division of Corporation Finance Manual of      Publicly Available Telephone Interpretations (Interpretation 17.06). As      permitted by Interpretation 17.06, management has asserted that it has      policies and procedures in place designed to provide reasonable assurance      that the Vendors’ activities comply in all material respects with the      servicing criteria applicable to each Vendor. The Servicer’s management is      solely responsible for determining that it meets the SEC requirements to      apply Interpretation 17.06 for the Vendors and related      criteria; |
