  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. Attached as Exhibit AA to the Pooling and Servicing Agreement incorporated by reference as Exhibit 4.1 to this report is a chart identifying the entities participating in a servicing function for the transaction responsible for each applicable servicing criterion set forth in Item 1122(d).
  The following material instances of noncompliance were reported by the Corporate Trust Services Division of Wells Fargo Bank, National Association (“Wells Fargo Bank”) in its reports attached hereto as Exhibit 33.4 and Exhibit 33.5 under Item 15:
  The assessment of compliance with applicable servicing criteria for the twelve months ended December 31, 2012, furnished pursuant to Item 1122 of Regulation AB by the Corporate Trust Services Division of Wells Fargo Bank for its platform, discloses that material instances of noncompliance occurred with respect to the servicing criteria described in Items 1122(d)(3)(i)(B) and 1122(d)(3)(ii) of Regulation AB.
  There were no instances of noncompliance for the transaction to which this Form 10-K relates that led to Wells Fargo Bank’s determination that there were material instances of noncompliance at the platform level.
  Schedule A
  Material Instances of Noncompliance by Wells Fargo Bank
  Wells Fargo Bank’s assessment of compliance with the Applicable Servicing Criteria set forth by the Securities and Exchange Commission in paragraph (d) of Item 1122 of Regulation AB as of December 31, 2012 and for the Period, disclosed that material instances of noncompliance occurred with respect to the servicing criteria set forth in both of Items 1122(d)(3)(i)(B) and 1122(d)(3)(ii), as follows:
  * With respect to servicing criterion 1122(d)(3)(i)(B), certain reports to investors did not provide information calculated in accordance with the terms specified in the transaction agreements.
  * With respect to servicing criterion 1122(d)(3)(ii), certain amounts due to investors were not allocated and remitted in accordance with timeframes, distribution priority and other terms set forth in the transaction agreements.
  Schedule B
  Wells Fargo Bank’s Discussion of Material Instances of Noncompliance by Wells Fargo Bank
  Disclosure: During the Period, Wells Fargo Bank identified Payment Errors (as defined below) and Reporting Errors (as defined below) on certain residential mortgage-backed securities ("RMBS") transactions in the Platform. Although no individually identified error, in and of itself, was found to be material to the Platform, when the errors were considered in the aggregate, Wells Fargo Bank determined that, for Platform purposes, there were material instances of noncompliance with respect to both Items 1122(d)(3)(i)(B) and 1122(d)(3)(ii) of Regulation AB.
  For purposes of this Schedule B, the term "Payment Errors" means the identified payment errors that occurred during the Period and that, when considered in the aggregate, led to Wells Fargo Bank’s determination that there was a material instance of noncompliance for the Platform with respect to Item 1122(d)(3)(i)(B) of Regulation AB. For purposes of this Schedule B, the term "Reporting Errors" means the identified reporting errors that occurred during the Period and that, when considered in the aggregate, led to Wells Fargo Bank’s determination that there was a material instance of noncompliance for the Platform with respect to Item 1122(d)(3)(ii) of Regulation AB.
  The identified Payment Errors and Reporting Errors on such RMBS transactions were attributable to certain failures in processes relating to waterfall calculations and reporting that, although adapted over time, still insufficiently addressed the impact of the unprecedented levels of collateral degradation in RMBS transactions on the calculation of principal and interest
 payments and losses and associated investor reporting.
  Scope of the Material Instances of Noncompliance: The identified Payment Errors and Reporting Errors that led to Wells Fargo Bank’s determination that material instances of noncompliance with respect to the Platform had occurred were limited to certain RMBS transactions in the Platform. There were no identified Payment Errors or Reporting Errors for non-RMBS transactions in the Platform which contributed to Wells Fargo Bank’s determination that there were material instances of noncompliance for the Platform. In some instances, the identified Payment Errors which contributed to Wells Fargo Bank’s determination that there were material instances of noncompliance for the Platform were also considered material to the transactions on which they occurred. None of the identified Reporting Errors which contributed to Wells Fargo Bank’s determination that there were material instances of noncompliance for the Platform were considered material for a particular transaction. For all transactions in the Platform (including RMBS transactions with identified Payment Errors and Reporting Errors), Wells Fargo Bank delivered an Item 1123 certification to the extent it was required to do so pursuant to the requirements of the applicable transaction documents and Regulation AB. Where there was an identified Payment Error that was considered material for an individual transaction, the Item 1123 certification included a description of the nature and scope of such error.
  Remediation: Appropriate actions have been taken or are in the process of being taken to remediate the identified Payment Errors and Reporting Errors that led to Wells Fargo Bank’s determination that material instances of noncompliance with respect to the Platform had occurred. Further, adjustments have been or will be made to the waterfall calculations and other operational processes and quality control measures applied to the RMBS transactions in the Platform to minimize the risk of future payment and reporting errors.
