   Item 1117 of Regulation AB, Legal Proceedings.

   The registrant knows of no material pending legal proceeding involving the
   trust or any party related to the trust, other than routine litigation
   incidental to the duties of those respective parties, and the following,
   with respect to UBS Real Estate Securities Inc ("UBSRES"), the Sponsor and a
   mortgage loan seller:

   In February 2012, Assured Guaranty filed suit against UBSRES in New York
   State Court asserting claims for breach of contract and declaratory relief
   based on UBSRES' alleged failure to repurchase allegedly defective mortgage
   loans with an original principal balance of at least $997 million that serve
   as collateral for residential mortgage-backed securities sponsored by the
   company and insured in part by Assured Guaranty. Assured Guaranty also
   claims that UBSRES breached representations and warranties concerning the
   mortgage loans and breached certain obligations under commitment letters.
   Assured Guaranty seeks unspecified damages that include payments on current
   and future claims made under Assured Guaranty insurance policies totaling
   approximately $308 million at the time of the filing of the complaint, as
   well as compensatory and consequential losses, fees, expenses and
   pre-judgment interest.  The case was removed to federal court, and in
   August 2012, the Court granted UBSRES' motion to dismiss Assured Guaranty's
   claims for breach of UBSRES' contractual repurchase obligations, holding
   that only the trustee for the securitization trust has the contractual right
   to enforce those obligations.  The Court also granted UBSRES' motion to
   dismiss Assured Guaranty's claims for declaratory relief. The Court denied
   UBSRES' motion to dismiss Assured Guaranty's claims for breach of
   representation and warranty and breach of the commitment letters.  The case
   is now in discovery.  In October 2012, following the Court's holding that
   only the trustee may assert claims seeking to enforce UBSRES' repurchase
   obligations, the residential mortgage-backed securities trusts at issue in
   the Assured Guaranty litigation filed a related action in the Southern
   District of New York seeking to enforce UBSRES' obligation to repurchase
   loans with an original principal balance of approximately $2 billion for
   which Assured Guaranty had previously demanded repurchase. UBS's motion to
   dismiss the suit filed by the trusts is pending.  With respect to the
   portion of the loans subject to this suit that were originated by
   institutions still in existence, UBS will seek to enforce its indemnity
   rights against those institutions.

   In April 2012, the Federal Housing Finance Agency, as conservator for
   Freddie Mac, filed a notice and summons in New York Supreme Court
   initiating suit against UBSRES for breach of contract and declaratory relief
   arising from alleged breaches of representations and warranties in
   connection with certain mortgage loans and UBSRES' alleged failure to
   repurchase such mortgage loans.  The complaint for this suit was filed in
   September 2012 and seeks, among other relief, specific performance of
   UBSRES' alleged loan repurchase obligations for at least $94 million in
   original principal balance of loans for which Freddie Mac had previously
   demanded repurchase; no damages are specified.  UBS's motion to dismiss the
   suit is pending.

   UBSRES, or its predecessor, Paine Webber Real Estate Securities, Inc., have
   been named as defendants, along with numerous other entities, in five
   purported class action lawsuits pending in Missouri.  Plaintiffs in each
   case are individuals who entered into second mortgages with various second
   mortgage originators.  Plaintiffs seek to represent state-wide classes in
   Missouri and assert violations of Missouri's Second Mortgage Loan Act.  The
   relief sought by Plaintiffs includes a refund of fees charged and interest
   paid in connection with their loans, relief from making future payments of
   interest and principal, punitive damages and attorneys' fees.  The five
   cases pending against UBS in Missouri are: Baker v. Century Financial
   Group, Inc., CV100-4294 CC (Clay County, Liberty); Beaver v. U.S. Bank
   Trust National Association, 03-CV-213643 (Jackson County, Independence);
   Gilmor v. Preferred Credit Corporation, CV100-4263 CC (Clay County,
   Liberty); Thomas v. U.S. Bank, N.A., N.D., 5:11-cv-06013 (W.D. MO., Western
   Division); and Mayo v. GMAC Mortgage, LLC, et al., 4:08-CV-568 (W.D. MO.,
   Western Division).

   UBSRES does not hold, and never held, any of the second mortgage loans at
   issue in the Baker or Gilmor cases.  Regarding the Beaver case, the Court
   has certified the case as a class action.  With respect to the Thomas case,
   the case was remanded to Missouri state court in August 2009 after having
   been removed to federal district court in 2004.  Plaintiffs filed an
   amended complaint in January 2011, adding a new defendant, and the case was
   thereafter removed to federal court.  In September 2012, the Court granted
   plaintiffs leave to amend the complaint.  On January 11, 2013, UBS re-filed
   its motion to dismiss for lack of standing and on March 12, 2013,
   plaintiffs filed their response. UBS will be filing a reply in support of
   its motion to dismiss on April 12, 2013.  The Mayo case was settled on
   March 20, 2013.

   UBSRES, along with certain affiliates, is named as a defendant in ten
   lawsuits brought by purchasers of residential mortgage-backed securities
   (RMBS) asserting claims under federal securities law or under state
   securities and/or state common law based on alleged misrepresentations
   or omissions in offering documents for approximately $10.4 billion in
   original face amount of residential mortgage-backed securities
   underwritten and issued by affiliates.  These lawsuits include a putative
   class action filed in federal court in New Jersey asserting violations of
   the federal securities laws against various UBS entities, including UBSRES,
   in connection with $2.6 billion in original face amount of UBS-sponsored
   RMBS.  The suit was dismissed with prejudice on statute of limitations
   grounds in July 2012. The named plaintiff has appealed the dismissal and
   the appeal remains pending.

   UBSRES also has tolling agreements with certain institutional purchasers
   of RMBS concerning their potential claims related to purchases of RMBS
   sponsored by UBSRES.
