| 1.   | CitiMortgage,      Inc. (the “Servicer”) is responsible for assessing compliance with the      applicable servicing criteria set forth in  Item 1122(d) of      Regulation AB of the Securities and Exchange Commission, as set forth in      Exhibit A hereto, in connection with the servicing of individual      residential mortgage-backed transactions subsequent to January 1, 2006 for      which the Servicer performs a particular servicing function pursuant to a      servicing agreement with a third party, utilizing the Fidelity loan      servicing  system (the “Platform”) as of and for the period      March 1, 2007 through December 31,2007; |
|----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 2.   | The      Servicer has engaged certain vendors (the “Vendors”) to perform specific,      limited or scripted activities as of and for the period March 1, 2007      through December 31, 2007. As set forth in Exhibit A hereto, the      Servicer’s management has determined that these Vendors are not considered      a “servicer” as defined in Item 1101(j) of Regulation AB, and the      Servicer’s management has elected to take responsibility for assessing      compliance with the servicing criteria applicable to each Vendor as      permitted by Interpretation 17.06 of the SEC Division of Corporation      Finance Manual of Publicly Available Telephone Interpretations      (Interpretation 17.06). As permitted by Interpretation 17.06, management      has asserted that it 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 Servicer’s management is solely responsible for determining that it      meets the SEC requirements to apply Interpretation 17.06 for the Vendors      and related criteria; |

| 3.   | Except      as set forth in paragraph 4 below, the Servicer used the criteria set      forth in paragraph (d) of Item 1122 of Regulation AB to assess the      compliance with the applicable servicing criteria as of and for the period      March 1, 2007 through December 31,2007; |
|----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 4.   | The      criteria listed as Inapplicable Servicing Criteria on Exhibit A hereto are      inapplicable to the Servicer based on the activities it performs with      respect to individual residential mortgage-backed securities transactions      involving the Platform; |
|----------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 5.   | The      Servicer has complied, in all material respects, with the applicable      servicing criteria as of and for the period March 1, 2007 through December      31, 2007; |
|----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 6.   | The      Servicer has not identified and is not aware of any material instance of      noncompliance by the Vendors with the applicable servicing criteria as of      and for the period March 1, 2007 through December 31,  2007; |
|----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 7.   | The      Servicer has not identified any material deficiency in its policies and      procedures to monitor the compliance by the Vendors with the applicable      servicing criteria as of and for the period March 1, 2007 through December      31, 2007; and |
