     Item 1117 of Regulation AB, Legal Proceedings.

     In December 2005, a putative class action was filed against NovaStar
     Mortgage,Inc.("NMI") in the United States District Court for the Western
     District of Washington entitled Pierce et al. v. NovaStar Mortgage, Inc.
     Plaintiffs contend that NMI failed to disclose prior to closing that a
     broker payment would be made on their loans, which was an unfair and
     deceptive practice in violation of the Washington Consumer Protection
     Act.  Plaintiffs seek excess interest charged, and treble damages as
     provided in the Washington Consumer Protection Act and attorney's fees.
     On October 31, 2006, the district court granted plaintiffs' motion to
     certify a Washington state class.  NMI sought to appeal the grant of
     class certification; however, a panel of the Ninth Circuit Court of
     Appeals denied the request for interlocutory appeal so review of the
     class certification order must wait until after a final judgment is
     entered, if necessary.  The case is set for trial on April 23, 2007.
     NMI believes that it has valid defenses to plaintiffs' claims and it
     intends to vigorously defend against them.

     In addition, NMI is currently a party to various other legal proceedings
     and claims, including, but not limited to, breach of contract claims,
     class action or individual claims for violations of the RESPA, FLSA,
     federal and state laws prohibiting employment discrimination, federal
     and state laws prohibiting discrimination in lending and federal and
     state licensing and consumer protection laws.

     While management, including internal counsel, currently believes that
     the ultimate outcome of all these proceedings and claims will not have
     a material adverse effect on NMI financial condition or results of
     operations, litigation is subject to inherent uncertainties. If an
     unfavorable ruling were to occur, there exists the possibility of a
     material adverse impact on NMI financial condition and results of
     operations.

     Item 1119 of Regulation AB, Affiliations and Certain Relationships and
     Related Transactions.
     None.
