administrator of the 10000 Santa Monica Boulevard Mortgage Loan, the Grand
Canal Shoppes Mortgage Loan, the Maui Portfolio Mortgage Loan, the Meidinger

Equity Retail & Industrial Portfolio Mortgage Loan are omitted from this
Annual Report on Form 10-K as the certificate administrator pursuant to the
related pooling and servicing agreement or trust and servicing agreement does
not perform any activities that address servicing criteria with respect to the

criteria in Item 1108(a)(2)(i) through (iii) of Regulation AB.

special servicer of the 10000 Santa Monica Boulevard Mortgage Loan and K-Star

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 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.
