Management Assessment

Management of the Cenlar FSB (the Company) 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 relating to the servicing of residential mortgage loans (the Platform), except for servicing criteria 1122(d)(1)(iii) Backup Servicer, as of and for the year ended December 31, 2013. This
criterion is not applicable to the Company because the Company does not perform activities with respect to the Platform relating to this criterion. Appendix A identifies the individual asset-backed transactions and securities defined by management
as constituting the Platform. With respect to servicing criteria 1122 (d)(2)(vi) and 1122 (d)(4)(xi), management has engaged various vendors to perform the activities required by these servicing criteria. The Companys management has determined
that none of these vendors is considered a servicer as defined in Item 1101(j) of Regulation AB, and the Companys management has elected to take responsibility for assessing compliance with the servicing criteria applicable to each
vendor as permitted by Interpretation 17.06 of the SEC Division of Corporation Finance Manual of Publicly Available Telephone Interpretations (Interpretation 17.06). Management has policies and procedures in place designed to provide
reasonable assurance that the vendors activities comply in all material respects with the servicing criteria applicable to each vendor. The Companys management is solely responsible for determining that it meets the SEC requirements to
apply Interpretation 17.06 for the vendors and related criteria.

The Companys management has assessed the Companys compliance with the
applicable servicing criteria as of and for the year ended December 31, 2013. In making this assessment, management used the criteria set forth by the Securities and Exchange Commission in paragraph (d) of Item 1122 of Regulation AB.

Based on such assessment, management has concluded that, as of and for the year ended December 31, 2013, the Company has complied in all material respects
with the servicing criteria, except for the servicing criteria 1122(d)(1)(iii) Backup Server, set forth in Item 1122(d) of Regulation AB of the Securities and Exchange Commission relating to the servicing of the Platform.

KPMG LLP, an independent registered public accounting firm, has issued an attestation report with respect to managements assessment of compliance with
the applicable servicing criteria as of and for the year ended December 31, 2013.
