The transactions covered by this report include all residential mortgage-backed securities that were completed on or after January 1, 2006 that were registered with the Securities and Exchange Commission pursuant to the Securities Act of 1933 (the "Platform"), as listed on Appendix A.

The Asserting Party 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 Asserting Party is responsible for determining that it meets the SEC requirements to apply Interpretation 17.06 for the Vendors and related criteria. The Asserting Party elects to take responsibility for assessing compliance with the servicing criteria or portion of the servicing criteria applicable to such Vendors for servicing criteria 1122(d)(4)(xi) and 1122(d)(4)(xii). The Asserting Party has obtained an assertion of management and accompanying 1122 attestation report from the Vendor performing servicing criteria 1122(d)(2)(i) and 1122(d)(4)(iv). The Asserting Party has assessed compliance with the Applicable Servicing Criteria for the Reporting Period and has concluded that it has complied, in all material respects, with the Applicable Servicing Criteria during the Reporting Period with respect to the Platform taken as a whole. Ernst & Young LLP, an independent registered public accounting firm, has issued an attestation report for the Platform on the Asserting Party's assessment of compliance with the Applicable Servicing Criteria as of and for the Reporting Period as set forth in this assertion.
