Item 1117 of Regulation AB.        Legal Proceedings.

              A complaint filed in state superior court in Los Angeles,
              California alleges violations of the federal securities laws by
              various parties who participated in certain securitization
              transactions effected by CWALT, Inc. between January 2005 and
              June 2007. The complaint names as defendants Countrywide Home
              Loans, Inc., Countrywide Home Loans Servicing LP, Countrywide
              Securities Corporation, CWALT, Inc. and certain individuals who
              served as directors of CWALT, Inc. during the applicable period,
              along with other unaffiliated entities. The complaint also names
              as defendants certain securitization trusts (including the
              Issuing Entity) formed by CWALT, Inc. between January 2005 and
              June 2007. The complaint seeks relief on behalf of a putative
              class of plaintiffs who acquired the securities issued by the
              various securitization trusts. The complaint alleges, among
              other things, that the mortgage loans transferred to the various
              securitization trusts were not originated in accordance with the
              underwriting guidelines and underwriting process that were
              disclosed in the applicable prospectus supplements. The
              complaint seeks unspecified monetary damages and other forms of
              relief. Countrywide Home Loans, Inc., Countrywide Home Loans
              Servicing LP, Countrywide Securities Corporation and CWALT, Inc.
              intend to defend the action vigorously.
