No entity or group of affiliated entities provides any external credit enhancement or other support for the certificates within this transaction as described under Item 1114(a) of Regulation AB.

Item 1115(b) of Regulation AB, Certain Derivatives Instruments (Financial Information).

No entity or group of affiliated entities provides any derivative instruments or other support for the certificates within this transaction as described under Item 1115 of Regulation AB.

Item 1117 of Regulation AB, Legal Proceedings.

The registrant knows of no legal proceeding pending against the sponsors, depositor, trustee, issuing entity, servicer contemplated by Item 1108(a)(3) of Regulation AB, originator contemplated by Item 1110(b) of Regulation AB, or other party contemplated by Item 1100(d)(1) of Regulation AB, or of which any property of the foregoing is the subject, that is material to security holders.

Item 1119 of Regulation AB, Affiliations and Certain Relationships and Related Transactions.

The seller and servicing administrator, the sponsor and the depositor are each either directly or indirectly wholly-owned subsidiaries of Redwood Trust, Inc. There is not currently, and there was not during the past two years, any material business relationship, agreement,

arrangement, transaction or understanding that is or was entered into outside the ordinary course of business or is or was on terms other than would be obtained in an arm’s length transaction with an unrelated third party, between (a) any of the seller, the sponsor, the depositor and the issuing entity on the one hand and (b) any of the trustee, any servicer, the custodian, the master servicer, the securities administrator or either originator of the mortgage loans on the other hand.

Item 1122 of Regulation AB, Compliance with Applicable Servicing Criteria.

The reports on assessment of compliance with the servicing criteria for asset-backed securities and the related attestation reports on such assessments of compliance are attached hereto under Item 15.

The registrant has prepared the Table below in connection with this transaction. The Table shows, in one compiled format, which entity participating in a servicing function for this transaction was assigned responsibility for each criterion in Item 1122(d). In the Table below, certain criteria are not applicable, given the structure of the offering, and accordingly no entity is assigned responsibility for such criteria.

Christiana Trust, a division of Wilmington Savings Fund Society FSB (“Christiana”), the trustee, does not participate in any servicing function for the transaction that is the subject of this 10-K filing. Therefore, there is no reference to Christiana in the chart below; nor does this 10-K filing include any assessment or auditor report from Christiana. Finally, any discrepancies between the chart below and the assessment of compliance exhibit provided by any party listed in the chart is explained by the fact that the chart is specific to the transaction that is the subject of this 10-K filing, whereas each party’s respective assessment of compliance is issued on a platform basis and includes coverage of other additional transactions that are not the subject of this 10-K filing.

*	The Revised PSA inadvertently and mistakenly indicates by “X” that Citibank, N.A. performs Reg AB Item 1122(d)(4)(xiv). However, this Chart, as well as Citibank N.A.’s management assessment report and report of the independent accountants are accurate in that Reg AB Item 1122(d)(4)(xiv) is not performed by Citibank, N.A. This Reg AB Item 1122(d)(4)(xiv) servicing criteria function is being performed by other parties. In this SEMT 2013-4 transaction, the Reg AB Item 1122(d)(4)(xiv) servicing criteria function is performed by CTCNA, as master servicer, and by underlying servicers JPMorgan Chase Bank, N.A. and Cenlar FSB.

**	The Cenlar Servicing Agreement indicates by “X” that Cenlar FSB performs Reg AB Items 1122(d)(4)(i-ii). However, Cenlar FSB’s management assessment report and report of the independent accountants state that Reg AB Items 1122(d)(4)(i-ii) are not performed by Cenlar FSB. In this SEMT 2013-4 transaction, the Reg AB Items 1122(d)(4)(i-ii) servicing criteria functions, as to Cenlar FSB, are instead performed by CTCNA, as custodian.



***	The JPMorgan Chase Bank, N.A. Servicing Agreement indicates by “X” that JPMorgan Chase Bank, N.A. performs Reg AB Items 1122(d)(4)(i-ii). However, JPMorgan Chase Bank, N.A.’s management assessment report and report of the independent accountants state that Reg AB Items 1122(d)(4)(i-ii) are not performed by JPMorgan Chase Bank, N.A.. In this SEMT 2013-4 transaction, the Reg AB Items 1122(d)(4)(i-ii) servicing criteria functions, as to JPMorgan Chase Bank, N.A., are instead performed by CTCNA as custodian.
