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, 2017, 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 activates performed by the Company during the
year ended December 31, 2017 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.

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 vendors 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, 2017 for the commercial real estate mortgage loans platform is fairly stated, in all material respects.
