Management’s Assertion on Compliance with Item 1122 Criteria

LaSalle Bank National Association (the "Asserting Party") is responsible for assessing its compliance with the applicable servicing criteria set forth in Item 1122(d) of Regulation AB (17 C.F.R, 229.1122(d)) as indicated on Exhibit A annexed hereto entitled "1122 Servicing Criteria to be Addressed in Assessment of Compliance" (the "Servicing Criteria").

The Asserting Party has assessed the effectiveness of its compliance with the applicable Servicing Criteria as of December 31, 2006, and for the period of January 1, 2006 through December 31, 2006 (the "Reporting Period"). In making this assessment, the Asserting Party used the criteria set forth by the Securities and Exchange Commission in paragraph (d) of Item 1122 of Regulation AB.

Based on such assessment, the Asserting Party believes that, as of December 31, 2006 and for the Reporting Period, it has complied in all material respects with the servicing criteria set forth in Item 1122(d) of Regulation AB for the servicing activities it performs in the asset-backed securities transactions detailed on Exhibit B. For servicing criteria 1122(d)(3)(i)(A) and (B), this assertion covers only the information on the report to investors that is required by the respective transaction agreements.

Ernst and Young, an independent registered public accounting firm, has issued an attestation report with respect to the Asserting Party’s assessment of compliance with the Servicing Criteria as of December 31, 2006 and for the Reporting Period. The asset-backed securities transactions to which this assertion and the attestation report relate are listed on Exhibit B.
