combination, including the Colorado Center Mortgage Loan, is being serviced and
administered pursuant to the trust and servicing agreement for the BXP Trust
2017-CC Transaction, which is incorporated by reference as Exhibit 4.2 to this
Annual Report on Form 10-K.

approximately 5.7% of the asset pool of the issuing entity as of its cut-off
date. The Park Square Mortgage Loan is an asset of the issuing entity and

combination, including the Park Square Mortgage Loan, is being serviced and
administered pursuant to the pooling and servicing agreement for the BANK
2017-BNK8 Transaction, which is incorporated by reference as Exhibit 4.3 to
this Annual Report on Form 10-K. The Griffin Portfolio Mortgage Loan and the
U.S. Industrial Portfolio III Mortgage Loan, each previously an asset of the
issuing entity being serviced under the pooling and servicing agreement for the
BANK 2017-BNK8 Transaction, were not an asset of the issuing entity during the
reporting period and are omitted from this Annual Report on Form 10-K and will
be omitted from subsequent Annual Reports on Form 10-K.

 The Exhibit Index describes
exhibits provided by certain parties (in their capacities indicated on the
Exhibit Index) with respect to the Bass Pro & Cabela's Portfolio Mortgage
Loan, which constituted approximately 2.2% of the asset pool of the issuing
entity as of its cut-off date. The Bass Pro & Cabela's Portfolio
Mortgage Loan is an asset of the issuing entity and is part of a loan
combination that includes the Bass Pro & Cabela's Portfolio Mortgage Loan
and eleven other pari passu loans, which are not assets of the issuing
entity. A pari passu portion of the loan combination was securitized in
the GS Mortgage Securities Trust 2017-GS8 transaction, Commission File Number
333-207677-07 (the " GSMS 2017-GS8 Transaction "). This loan combination,
including the Bass Pro & Cabela's Portfolio Mortgage Loan, is being
serviced and administered pursuant to the pooling and servicing agreement for
the GSMS 2017-GS8 Transaction, which is incorporated by reference as Exhibit
4.4 to this Annual Report on Form 10-K.

 The master servicer of a pooling
and servicing agreement or trust and servicing agreement also functions as the
primary servicer of the related mortgage loans serviced and administered
pursuant to such agreement unless a separate primary servicer is identified
herein. If this report does not identify a separate primary servicer, the
servicer compliance statement provided by the master servicer under any such
agreement also encompasses its responsibilities as primary servicer of the
related mortgage loan or mortgage loans.

 Wells Fargo Bank, National
Association is the master servicer and certificate administrator of the
mortgage loans serviced under the Pooling and Servicing Agreement and the
primary servicer of the Park Square Mortgage Loan, the Colorado Center Mortgage
Loan and the Bass Pro & Cabela's Portfolio Mortgage Loan. As a result,
Wells Fargo Bank, National Association is a "servicer" as defined in Item
1108(a)(2)(iii) of Regulation AB, in the capacities described above, because it
is servicing mortgage loans that constituted 10% or more of the assets of the
issuing entity as of its cut-off date. The assessments of compliance with
applicable servicing criteria, accountants' attestation reports and servicer
compliance statements delivered by Wells Fargo Bank, National Association in
the capacities described above are listed in the Exhibit Index.

 Wells Fargo Bank, National
Association is the custodian of the mortgage loans serviced under the Pooling
and Servicing Agreement, the Park Square Mortgage Loan, the Colorado Center
Mortgage Loan and the Bass Pro & Cabela's Portfolio Mortgage Loan. As
a result, Wells Fargo Bank, National Association is a servicing function
participant in the capacities described above, because it is servicing mortgage
loans that constituted 5% or more of the assets of the issuing entity as of its
cut-off date. The assessments of compliance with applicable servicing criteria
and accountants' attestation reports delivered by Wells Fargo Bank, National
Association in the capacities described above are listed in the Exhibit Index.

 Wilmington Trust, National
Association acts as trustee of the mortgage loans serviced under the Pooling
and Servicing Agreement, the Colorado Center Mortgage Loan, the Park Square
Mortgage Loan and the Bass Pro & Cabela's Portfolio Mortgage Loan.
Pursuant to the Pooling and Servicing Agreement, the trust and servicing
agreement for the BXP Trust 2017-CC Transaction, the pooling and servicing
agreement for the BANK 2017-BNK8 Transaction and the pooling and servicing
agreement for the GSMS 2017-GS8 Transaction, the trustee is required to provide
an assessment of compliance with applicable servicing criteria solely with
respect to Item 1122(d)(2)(iii) of Regulation AB (regarding advances of funds
or guarantees regarding collections, cash flows or distributions, and any
interest or other fees charged for such advances, are made, reviewed and
approved as specified in the transaction agreements). However, during the
reporting period, the trustee did not perform any servicing function with
respect to the servicing criteria specified in Item 1122(d)(2)(iii) of
Regulation AB. The master servicer or the special servicer, to the extent
required, performed the servicing function identified with respect to Item
1122(d)(2)(iii) of Regulation AB, and each such party included Item
1122(d)(2)(iii) of Regulation AB in the assessment of compliance with
applicable servicing criteria and accountant's attestation report for the
subject transaction. As a result, this Annual Report on Form 10-K does
not include an assessment of compliance with applicable servicing criteria of
the trustee. One or more other servicers of the mortgage loans serviced under
the Pooling and Servicing Agreement, the Colorado Center Mortgage Loan, the
Park Square Mortgage Loan and the Bass Pro & Cabela's Portfolio Mortgage
Loan have delivered one or more assessments of compliance with respect to Item
1122(d)(2)(iii) of Regulation AB.

 This Annual Report on Form 10-K
includes assessments of compliance with applicable servicing criteria and
accountants' attestation reports from CoreLogic Solutions, LLC. This
entity was engaged by the master servicer under the Pooling and Servicing
Agreement and the primary servicer of the Colorado Center Mortgage Loan, the
Park Square Mortgage Loan and the Bass Pro & Cabela's Portfolio Mortgage
Loan to remit tax payments received from the escrow accounts of borrowers to
local taxing authorities, to report tax amounts due, to verify tax parcel
information, and to verify non-escrow tax payments. These servicing functions
are included within the servicing criteria set forth in Items 1122(d)(4)(xi)
and 1122(d)(4)(xii) of Regulation AB. Therefore, under the
principles-based definition of "servicer" set forth in Item 1101(j) of
Regulation AB that looks to the functions that an entity performs, this vendor
is a "servicer" for the purposes of Item 1122 of Regulation AB. See
Compliance and Disclosure Interpretations, Section 301.01 (Item 1101(j)).

 This Annual
Report on Form 10-K includes an assessment of compliance with applicable
servicing criteria, accountants' attestation report and servicer compliance
statement from Computershare Trust Company, National Association (" CTCNA ").
CTCNA was engaged by Wells Fargo Bank, National Association (" Wells Fargo "),
in its capacity as certificate administrator and custodian, to perform certain
specified servicing functions identified in the assessment of compliance with
applicable servicing criteria and accountants' attestation reports. Wells
Fargo engaged CTCNA in connection with the sale of Wells Fargo's corporate
trust services business to CTCNA and its affiliates. Further, under the
principles-based definition of "servicer" set forth in Item 1101(j) of
Regulation AB that looks to the functions that an entity performs, this party
is a "servicer" for the purposes of Item 1123 of Regulation AB. See
Compliance and Disclosure Interpretations, Section 301.01 (Item 1101(j)).

 The assessments of compliance with
applicable servicing criteria, accountants' attestation reports and servicer
compliance statements of the certificate administrator of the Colorado Center
Mortgage Loan, the Park Square Mortgage Loan and the Bass Pro & Cabela's
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 issuing entity and because they
are each not a "servicer" that meets the criteria in Item 1108(a)(2)(i) through
(iii) of Regulation AB.

 With respect to the pari passu
loan combinations that include the Colorado Center Mortgage Loan, the Park
Square Mortgage Loan and the Bass Pro & Cabela's Portfolio Mortgage Loan,

attestation reports on assessment of compliance with servicing criteria of

Cabela's Portfolio Mortgage Loan on and after May 10, 2023 and Pentalpha
Surveillance LLC as operating advisor of the Bass Pro & Cabela's Portfolio
Mortgage Loan, listed on the Exhibit Index are omitted from this Annual Report
on Form 10-K as they are not required to be included on this Annual Report on
Form 10-K per Instruction 3 to Item 1122 of Regulation AB because they are
parties performing activities that address servicing criteria relating to 5% or
less of the assets of the issuing entity; and (ii) the servicer compliance
statements of LNR Partners, LLC as special servicer of the Park Square Mortgage
Loan, Argentic Services Company LP as special servicer of the Colorado Center
Mortgage Loan, Midland Loan Services, a Division of PNC Bank, National
Association as special servicer of the Bass Pro & Cabela's Portfolio
Mortgage Loan prior to May 10, 2023, K-Star Asset Management LLC as special
servicer of the Bass Pro & Cabela's Portfolio Mortgage Loan on and after
May 10, 2023, listed on the Exhibit Index are omitted from this Annual Report
on Form 10-K as they are not required by Item 1123 of Regulation AB to be
included on this Annual Report on Form 10-K because they are each an
unaffiliated party that is not a "servicer" that meets the criteria in Item
1108(a)(2)(i) through (iii) of Regulation AB.

following, with respect to Wells Fargo Bank, National Association, as
certificate administrator, and as 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.
