EXPLANATORY NOTES

The Exhibit Index describes exhibits provided by certain parties (in their
capacities indicated on the Exhibit Index) with respect to the La Gran Plaza Mortgage Loan, which constituted approximately 1.8% of the
asset pool of the issuing entity as of its cut-off date.  The La Gran Plaza Mortgage Loan is an asset of the issuing entity and is
part of a loan combination that includes the La Gran Plaza Mortgage Loan and two other pari passu loans, which are not assets of
the issuing entity. A pari passu portion of the loan combination was securitized in the COMM 2015-CCRE24 Mortgage Trust transaction,
Commission File Number 333-193376-21 (the “COMM 2015-CCRE24 Transaction”). This loan combination, including the La
Gran Plaza Mortgage Loan, is being serviced and administered pursuant to the pooling and servicing agreement for the COMM 2015-CCRE24
Transaction, which is incorporated by reference as Exhibit 4.2 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.

Park Bridge Lender Services LLC is the operating advisor of the mortgage
loans serviced under the Pooling and Servicing Agreement and the La Gran Plaza Mortgage Loan. As a result, Park Bridge Lender Services
LLC 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 Park Bridge Lender Services LLC in the capacities described above are listed in the
Exhibit Index.

Berkeley Point Capital LLC d/b/a Newmark is an affiliate of Cantor Commercial
Real Estate Lending, L.P., one of the sponsors.  Therefore, the Depositor included in this Annual Report on Form 10-K a servicer
compliance statement for Berkeley Point Capital LLC d/b/a Newmark pursuant to Item 1123.  Because Berkeley Point Capital LLC d/b/a
Newmark is servicing less than 5% of the pool assets, an assessment of compliance with applicable servicing criteria and an accountants’
attestation report pursuant to Item 1122 of Regulation AB are not required by Regulation AB.  As the attestation made in the servicer
compliance statement required by Item 1123 relates to a review of the servicing activities of Berkeley Point Capital LLC d/b/a Newmark
under the applicable servicing agreement, and that review was conducted in conjunction with the servicer’s preparation of its assessment
of compliance with applicable servicing criteria, that assessment of compliance with applicable servicing criteria and the accompanying
accountants’ attestation report are included in this Annual Report on Form 10-K for the sake of completeness.

Wilmington Trust, National Association acts as trustee of the mortgage loans
serviced under the Pooling and Servicing Agreement and the La Gran Plaza Mortgage Loan. Pursuant to the Pooling and Servicing Agreement
and the pooling and servicing agreement for the COMM 2015-CCRE24 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 and the La Gran Plaza Mortgage Loan have delivered one or more assessments of compliance with respect to Item 1122(d)(2)(iii)
of Regulation AB.

The assessment of compliance with applicable servicing criteria, accountants’
attestation report and servicer compliance statement of the certificate administrator of the La Gran Plaza Mortgage Loan is 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 it
is 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 combination that includes the
La Gran Plaza Mortgage Loan, (i) the reports on assessment of compliance with servicing criteria and attestation reports on assessment
of compliance with servicing criteria of Wells Fargo Bank, National Association as primary servicer and custodian of the La Gran Plaza
Mortgage Loan and LNR Partners, LLC as special servicer of the La Gran Plaza 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 Wells Fargo Bank, National Association as primary servicer of the La
Gran Plaza Mortgage Loan and LNR Partners, LLC as special servicer of the La Gran Plaza Mortgage Loan, 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.

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 Wells Fargo Bank, National Association, as Certificate Administrator and Custodian, and Deutsche Bank Trust Company Americas,
as Certificate Administrator and Custodian.



In December 2014, Phoenix Light SF Limited and certain related
entities and the National Credit Union Administration (NCUA) filed complaints in the United States District Court for the Southern District
of New York against Wells Fargo Bank, alleging claims against Wells Fargo Bank in its capacity as trustee for a number of residential
mortgage-backed securities trusts. Complaints raising similar allegations have been filed by Commerzbank AG in the Southern District of
New York and by IKB International and IKB Deutsche Industriebank in New York state court. In each case, the plaintiffs allege that Wells
Fargo Bank, 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. Wells Fargo
Bank previously settled two class action lawsuits with similar allegations that were filed in November 2014 and December 2016 by institutional
investors in the Southern District of New York and New York state court, respectively. In addition, Park Royal I LLC and Park Royal II
LLC have filed complaints in New York state court alleging Wells Fargo Bank, N.A., as trustee, failed to take appropriate actions upon
learning of defective mortgage loan documentation. In March 2021, the Company entered into an agreement to resolve the case filed by the
NCUA.



In addition to the foregoing cases, in August 2014 and August
2015 Nomura Credit & Capital Inc. (“Nomura”) and Natixis Real Estate Holdings, LLC (“Natixis”)
filed a total of seven third-party complaints against Wells Fargo Bank in New York state court. In the underlying first-party actions,
Nomura and Natixis have been sued for alleged breaches of representations and warranties made in connection with residential mortgage-backed
securities sponsored by them. In the third-party actions, Nomura and Natixis allege that Wells Fargo Bank, as master servicer, primary
servicer or securities administrator, failed to notify Nomura and Natixis of their own breaches, failed to properly oversee the primary
servicers, and failed to adhere to accepted servicing practices. Natixis additionally alleges that Wells Fargo Bank failed to perform
default oversight duties. Wells Fargo Bank has asserted counterclaims alleging that Nomura and Natixis failed to provide Wells Fargo Bank
notice of their representation and warranty breaches.



With respect to each of the foregoing litigations, Wells Fargo Bank believes plaintiffs'
claims are without merit and intends to contest the claims vigorously, but there can be no assurances as to the outcome of the litigations
or the possible impact of the litigations on Wells Fargo Bank or the related RMBS trusts.

Deutsche Bank Trust Company Americas (“DBTCA”) and Deutsche
Bank National Trust Company (“DBNTC”) have been sued by investors in civil litigation concerning their role as trustees
of certain residential mortgage-backed securities (“RMBS”) trusts.

On June 18, 2014, a group of investors, including funds managed by Blackrock
Advisors, LLC, PIMCO-Advisors, L.P., and others, filed an action against DBNTC and DBTCA in New York State Supreme Court alleging that
DBNTC and DBTCA failed to perform purported duties, as trustees for 544 private-label RMBS trusts, to enforce breaches of representations
and warranties as to mortgage loans held by the trusts and to enforce breaches by servicers of their mortgage loan servicing obligations
for the trusts. During the course of the litigation, plaintiffs dismissed the case from New York State Supreme Court and refiled two separate
cases, one in the U.S. District Court for the Southern District of New York (the “BlackRock SDNY Case”) and the other
in the Superior Court of California, Orange County (the “BlackRock California Case”). Pursuant to a settlement among
the parties, the BlackRock SDNY Case was dismissed on December 6, 2018, and the BlackRock California Case was dismissed on January 11,
2019.

On September 27, 2017, DBTCA was added as a defendant to a case brought by
certain special purpose entities including Phoenix Light SF Limited in the U.S. District Court for the Southern District of New York,
in which the plaintiffs previously alleged incorrectly that DBNTC served as trustee for all 43 of the trusts at issue. On September 27,
2017, plaintiffs filed a third amended complaint that names DBTCA as a defendant in addition to DBNTC. DBTCA serves as trustee for one
of the 43 trusts at issue. DBNTC serves as trustee for the other 42 trusts at issue. Plaintiffs’ third amended complaint brings
claims for violation of the U.S. Trust Indenture Act of 1939 (“TIA”); breach of contract; breach of fiduciary duty;
negligence and gross negligence; violation of New York’s Streit Act; and breach of the covenant of good faith. However, in the third
amended complaint, plaintiffs acknowledge that, before DBTCA was added to the case, the court dismissed plaintiffs’ TIA Act claims,
negligence and gross negligence claims, Streit Act claims, claims for breach of the covenant of good faith, and certain theories of plaintiffs’
breach of contract claims, and plaintiffs only include these claims to preserve any rights on appeal. Plaintiffs allege damages of “hundreds
of millions of dollars.” On November 13, 2017, DBNTC and DBTCA filed an answer to the third amended complaint. On December 7, 2018,
DBNTC and DBTCA filed a motion for summary judgment. Also on December 7, 2018, plaintiffs, jointly with Commerzbank AG (see description
of Commerzbank case below), filed a motion for partial summary judgment. On October 27, 2021, DBNTC and DBTCA filed a supplemental motion
for summary judgment relating to plaintiffs’ standing. On February 8, 2022, the court issued an order in which it granted DBNTC
and DBTCA’s supplemental motion for summary judgment, granted in part DBNTC and DBTCA’s initial motion for summary judgment,
and denied plaintiffs’ motion for partial summary judgment. As a result of that order, all of plaintiffs’ claims were dismissed
with prejudice.

On November 30, 2017, DBTCA was added as a defendant to a case brought by
Commerzbank AG (“Commerzbank”) in the U.S. District Court for the Southern District of New York, in which Commerzbank
previously alleged incorrectly that DBNTC served as trustee for all 50 of the trusts at issue. On November 30, 2017, Commerzbank filed
a second amended complaint that names DBTCA as a defendant in addition to DBNTC. DBTCA serves as trustee for 1 of the 50 trusts at issue.
DBNTC serves as trustee for the other 49 trusts at issue. Commerzbank’s second amended complaint brings claims for violation of
the TIA; breach of contract; breach of fiduciary duty; negligence; violation of the Streit Act; and breach of the covenant of good faith.
However, in the second amended complaint, Commerzbank acknowledges that, before DBTCA was added to the case, the court dismissed Commerzbank’s
TIA claims for the trusts governed by pooling and servicing agreements, as well as its Streit Act claims and claims for breach of the
covenant of good faith, and Commerzbank only includes these claims to preserve any rights on appeal. The second amended complaint alleges
that DBNTC and DBTCA caused Commerzbank to suffer “hundreds of millions of dollars in losses,” but the complaint does not
include a demand for money damages in a sum certain. On January 29, 2018, DBNTC and DBTCA filed an answer to the second amended complaint.
On December 7, 2018, DBNTC and DBTCA filed a motion for summary judgment. Also on December 7, 2018, Commerzbank, jointly with the Phoenix
Light plaintiffs, filed a motion for partial summary judgment. On February 8, 2022, the court issued an order in which it granted in part
DBNTC and DBTCA’s motion for summary judgment and denied plaintiffs’ motion for partial summary judgment. As a result of that
order, many of plaintiffs’ claims and theories were dismissed with prejudice. Discovery is ongoing.

On December 30, 2015, IKB International, S.A. in Liquidation and IKB Deutsche
Industriebank A.G. (collectively, “IKB”), as an investor in 37 RMBS trusts, filed a summons with notice in the Supreme
Court of the State of New York, New York County, against DBNTC and DBTCA as trustees of the trusts. On May 27, 2016, IKB served its complaint
asserting claims for breach of contract, breach of fiduciary duty, breach of duty to avoid conflicts of interest, violation of the Streit
Act, violation of the TIA, violation of Regulation AB, and violation of Section 9 of the Uniform Commercial Code. IKB alleges that DBNTC
and DBTCA are liable for over U.S. $268 million in damages. On October 5, 2016, DBNTC and DBTCA, together with several other trustees
defending lawsuits by IKB, filed a joint motion to dismiss. On January 6, 2017 and June 20, 2017, IKB voluntarily dismissed with prejudice
all claims as to seven trusts. On January 27, 2021, the court granted in part and denied in part DBNTC and DBTCA’s motion to dismiss.
The court granted the motion to dismiss with respect to IKB’s claims for violations of the Streit Act, Regulation AB, and Section
9 of the Uniform Commercial Code, as well as certain aspects of IKB’s claims for breach of contract, breach of fiduciary duty, and
violation of the TIA. The court denied the remainder of the motion to dismiss. IKB’s remaining claims for breach of contract, breach
of fiduciary duty, breach of duty to avoid conflicts of interest, and violation of the TIA will proceed. On May 10, 2021, DBNTC and DBTCA
filed a notice of appeal with the New York Supreme Court Appellate Division, First Department, regarding certain aspects of the court’s
order on the motion to dismiss. That appeal has been fully briefed. On May 20, 2021, IKB filed a notice of cross appeal with respect to
other aspects of that order. That appeal is being briefed. On June 2, 2021, IKB filed a motion for re-argument regarding certain aspects
of the court’s order on the motion to dismiss, which the court denied on August 3, 2021. On May 13, 2021, DBNTC and DBTCA filed
an answer to the complaint. On October 28, 2021, the parties filed a stipulation, voluntarily dismissing with prejudice all claims as
to seven additional trusts. On December 29, 2021, the parties filed a stipulation, voluntarily dismissing with prejudice all claims as
to one additional trust. Discovery is ongoing.

It is DBTCA’s belief that it has no pending legal proceedings (including,
based on DBTCA’s present evaluation, the litigation disclosed in the foregoing paragraphs) that would materially affect its ability
to perform its duties under the related servicing agreement for this transaction.
