Tel: +1 216 861 5000 Fax: +1 216 583 2013 ey.com Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholder KeyBank National
Association We have examined managements assertion, included in the Managements Assertion on Compliance with Regulation AB Servicing
Criteria, that KeyBank National Association, as successor by merger to KeyCorp Real Estate Capital Markets, Inc., (the Company) complied with the servicing criteria set forth in Item 1122 (d) of the Securities and Exchange Commissions
Regulation AB for the commercial real estate mortgage loans platform, as of and for the year ended December 31, 2018, except for 1122 (d)(3)(i)(b), 1122 (d)(3)(i)(c), 1122 (d)(3)(i)(d), 1122 (d)(3)(ii), 1122 (d)(3)(iii) and 1122 (d)(3)(iv), which
the Company has determined are not applicable to the activities performed by them with respect to the servicing platform covered by this report as noted in Appendix B. See Appendix A for the asset backed transactions covered by this platform.
Management is responsible for the Companys compliance with those servicing criteria. Our responsibility is to express an opinion on managements assertion about the Companys compliance with the servicing criteria based on our
examination. Our examination was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants
and the Public Company Accounting Oversight Board (United States) and accordingly, included examining, on a test basis, evidence about the Companys compliance with the applicable servicing criteria and performing such other procedures as we
considered necessary in the circumstances. Our examination included testing of less than all of the individual asset backed transactions and securities that comprise the Platform, testing of less than all of the servicing activities related to the
Platform and determining whether the Company processed those selected transactions and performed those selected activities in compliance with the servicing criteria and as permitted by Regulation AB Compliance and Disclosure Interpretations of the
Division of Corporation Finance, Section 200.06, Vendors Engaged by Servicers (C&DI 200.06). Furthermore, our procedures were limited to the selected transactions and servicing activities performed by the Company during the
period covered by this report. Our procedures were not designed to determine whether errors may have occurred either prior to or subsequent to our tests that may have affected the balances or amounts calculated or reported by the Company during the
period covered by this report for the selected transactions or any other transactions. Although the Company is responsible for assessing compliance with Item 1122(d)(1)(iii) of Regulation AB, there were no servicing activities performed by the
Company during the year ended December 31, 2018 that required these servicing criteria. We believe that the evidence we obtained is sufficient and appropriate to provide a reasonable basis for our opinion. Our examination does not provide a legal determination on the Companys compliance with the servicing criteria. 1  A member firm of Ernst

LOGO As described in managements assertion, for servicing criteria 1122 (d)(4)(xi)), the Company has engaged a vendor to
perform the activities required by this servicing criteria. The Company has determined that this vendor is not considered a servicer as defined in Item 1101(j) of Regulation AB, and the Company has elected to take responsibility for
assessing compliance with the applicable servicing criteria applicable to the vendor as permitted by C&DI 200.06. As permitted by C&DI 200.06, the Company has asserted that it has policies and procedures in place designed to provide
reasonable assurance that the vendors activities comply in all material respects with servicing criteria applicable to the vendor. The Company is solely responsible for determining that it meets the SEC requirements to apply C&DI 200.06
for the vendor and related criteria as described in its assertion, and we performed no procedures with respect to the Companys eligibility to apply C&DI 200.06. In our opinion, managements assertion that the Company complied with the servicing criteria set forth in Item 1122 (d) of the Securities and Exchange
Commissions Regulation AB, including servicing criteria 1122 (d)(4)(xi)) for which compliance is determined based on C&DI 200.06 as described above, as of and for the ended December 31, 2018 for the commercial real estate mortgage loans
platform is fairly stated, in all material respects.  LOGO February 21, 2019    A member firm of Ernst
