 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 Wells Fargo Bank, National Association, as trustee,
certificate administrator and custodian.

 In December 2014, Phoenix Light SF Limited (Phoenix Light)
and certain related entities filed a complaint in the United States District
Court for the Southern District of New York alleging claims against Wells Fargo
Bank, N.A., in its capacity as trustee for a number of residential
mortgage-backed securities (RMBS) trusts. Complaints raising similar
allegations have been filed by Commerzbank AG in the Southern District of New
York, IKB International and IKB Deutsche Industriebank (together, IKB) in New York
state court, and Park Royal I LLC and Park Royal II LLC in New York state
court. In each case, the plaintiffs allege that Wells Fargo Bank, N.A., as
trustee, caused losses to investors, and plaintiffs assert causes of action
based upon, among other things, the trustee's alleged failure to notify and
enforce repurchase obligations of mortgage loan sellers for purported breaches
of representations and warranties, notify investors of alleged events of
default, and abide by appropriate standards of care following alleged events of
default. In July 2022, the district court dismissed Phoenix Light's claims and
certain of the claims asserted by Commerzbank AG, and subsequently entered
judgment in each case in favor of Wells Fargo Bank, N.A. In August 2022, Phoenix
Light and Commerzbank AG each appealed the district court's decision to the
United States Court of Appeals for the Second Circuit. Phoenix Light dismissed
its appeal in May 2023, terminating its case. In October 2024, the Second
Circuit denied Commerzbank AG's appeal. In November 2023, Wells Fargo Bank,
N.A. entered into an agreement with IKB to resolve IKB's claims. Wells Fargo
Bank, N.A. previously settled two class actions filed by institutional
investors and an action filed by the National Credit Union Administration with
similar allegations.
