On June 18, 2014, a group of institutional investors filed a civil complaint in the Supreme Court of the State of New York, New York County, against Wells Fargo Bank, N.A., in its capacity as trustee under 276 residential mortgage backed securities ("RMBS") trusts, which was later amended on July 18, 2014, to increase the number of trusts to 284 RMBS trusts. On November 24, 2014, the plaintiffs filed a motion to voluntarily dismiss the state court action without prejudice. That same day, a group of institutional investors filed a civil complaint in the United States District Court for the Southern District of New York against Wells Fargo Bank, N.A., alleging claims against the bank in its capacity as trustee for 274 residential mortgage backed securities ("RMBS") trusts (the “Complaint”). In December 2014, the plaintiffs’ motion to voluntarily dismiss their original state court action was granted. As with the prior state court action, the Complaint is one of six similar complaints filed contemporaneously against RMBS trustees (Deutsche Bank, Citibank, HSBC, Bank of New York Mellon and US Bank) by a group of institutional investor plaintiffs. The Complaint against Wells Fargo Bank, N.A. alleges that the trustee caused losses to investors and asserts causes of action based upon, among other things, the trustee's alleged failure to (i) enforce repurchase obligations of mortgage loan sellers for purported breaches of representations and warranties, (ii) notify investors of alleged events of default purportedly caused by breaches by mortgage loan servicers, and (iii) abide by appropriate standards of care following alleged events of default. Relief sought includes money damages in an unspecified amount, reimbursement of expenses, and equitable relief. Other cases alleging similar causes of action have been filed against Wells Fargo Bank, N.A. and other trustees by RMBS investors in these and other transactions. There can be no assurances as to the outcome of the litigation, or the possible impact of the litigation on the trustee or the RMBS trusts. However, Wells Fargo Bank, N.A. denies liability and believes that it has performed its obligations under the RMBS trusts in good faith, that its actions were not the cause of any losses to investors, and that it has meritorious defenses, and it intends to contest the plaintiffs’ claims vigorously.

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

The information regarding this Item has been disclosed in the Prospectus of the Issuing Entity filed in a 424(b)(5) filing dated March 23, 2012.

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 assessment of compliance with applicable servicing criteria for the twelve months ended December 31, 2014, furnished pursuant to Item 1122 of Regulation AB by Key Bank National Association discloses that material instances of non-compliance occurred with respect to the servicing criteria described in Item 1122(d)(4)(xv) of Regulation AB. Such assessment of compliance is attached to this Form 10-K as Exhibit 33.2.

There were no instances of noncompliance for the transaction to which this Form 10-K relates that led to KeyBank National Association’s determination that there were material instances of noncompliance at the platform level.

The remainder of the paragraphs in this response to Item 1122 were provided by KeyBank National Association, and references to “KeyBank” in such paragraphs are references to KeyBank National Association.

1) KeyBank has identified the following material instances of noncompliance with servicing criteria 1122(d)(4)(xv) during the calendar year ended December 31, 2014 with respect to the transactions to which this Form 10-K relates:

1122(d)(4)(xv) – Any external enhancement or other support, identified in Item1114(a)(1) through (3) or item 1115 of Regulation AB, is maintained as set forth in the transaction agreements.

2) KeyBank has implemented the following remediation procedures:

1122(d)(4)(xv) - Regarding external enhancements, specifically letters of credit, it was discovered, upon transfer of the servicing of the mortgage loans to KeyBank from the previous servicer, that not all loans properly named KeyBank as the beneficiary on the letters of credit. A compliance test was performed on a sample of 19 loans and of this sample, 6 loans were identified in which the letters of credit, representing the external enhancements, were not transferred to KeyBank and therefore represent exceptions. The noncompliance in Item 1122 (d)(4)(xv) related to a servicing portfolio acquired by KeyBank during the previous year where the beneficiary of credit enhancements was not updated subsequent to acquisition. The following remediation procedures have been initiated by KeyBank: (i) the impacted mortgage loans have been identified, (ii) borrower contact has been initiated, (iii) corrective actions are underway and are being tracked and monitored by senior management, (iv) procedures have been revised to include new tracking and action steps to prevent this situation from recurring in the future, and (v) training has been provided to the relevant staff members to prevent a recurrence, and (vi) updates will be made to software systems to assist staff members with compliance.

During the calendar year ended December 31, 2014, no demands were made upon any of the impacted letters of credit, and thus, none of the affected transactions were materially impacted.
