Report on
Assessment of Compliance with SEC Regulation AB Servicing Criteria

Midland Loan Services (Midland), a division of PNC Bank, National
Association, is responsible for assessing compliance with the applicable servicing criteria set forth in Item 1122 (d) of Regulation AB of the Securities and Exchange Commission (Regulation AB), as set forth in Exhibit A.

Midland has assessed its compliance with the applicable servicing criteria as of and for the year ended December 31, 2017 (the Reporting
Period). In making this assessment, Midland used the criteria set forth by the Securities and Exchange Commission (SEC) in Item 1122(d) of Regulation AB. This report covers all transactions serviced on the Enterprise! Loan
Management System (the Platform).

Midland engaged certain vendors, which are not servicers as defined in item 1101(j) of Regulation AB (the
Vendors), to perform specific, limited or scripted activities related to portions of the servicing criteria as set forth in Exhibit A. Midland elects to take responsibility for assessing compliance with the servicing criteria or portion
of the servicing criteria applicable to such Vendors activities as set forth in Exhibit A. Midland has not identified and is not aware of any material instances of noncompliance by the Vendors with the applicable servicing criteria as of
December 31, 2017 and for the Reporting Period with respect to the Platform taken as a whole, nor has it identified any material deficiencies in its policies and procedures to monitor the compliance by the Vendors with the applicable servicing
criteria as of December 31, 2017 and for the Reporting Period with respect to the Platform taken as a whole.

Based on this assessment, Midland
believes that, as of and for the year ended December 31, 2017, Midland has complied in all material respects with the applicable servicing criteria set forth in Item 1122(d) of Regulation AB.

PricewaterhouseCoopers LLP, an independent registered public accounting firm, has issued an attestation report on Midlands assessment of compliance with
the applicable servicing criteria as of and for the year ended December 31, 2017.
