1.    Material Instances of Noncompliance by the Asserting Party


      The following instances of non-compliance by the Asserting Party have been
      identified with respect to the following provisions of Regulation AB Item
      1122(d):

      a.  Item 1122(d)(2)(vii)(D). Approximately 532 account reconciliations
          out of approximately 60,000 statements (or approximately 0.9%) with
          reconciling items were not resolved within 90 days of their
          identification, due to the migration of functions to personnel in a
          separate geographic location. All such reconciling items have been
          resolved in the meantime and processes and procedures are in place
          to provide for on-going compliance with this requirement;

      b.  Item 1122(d)(3)(i)(B) and (3)(ii). A programming change resulted in
          the miscalculation of some liquidation proceeds and the failure to
          include other liquidation proceeds, in the aggregate amount of
          approximately $9,694,614, in the September 2007 distribution with
          respect to 13 securitizations subject to Regulation AB. The servicer
          in each of the securitizations remitted the applicable shortfall
          amount on October 1, 2007 to the applicable Trustee as required by
          the applicable pooling and servicing agreement. The programming
          error was corrected in October 2007;

      c.  Item 1122(d)(3)(ii). Prepayment fees due to investors in 16 or more
          securitizations subject to Regulation AB were calculated incorrectly
          on certain loans with deferred interest, resulting in a shortfall in
          the distributions to those investors in an aggregate amount that is
          not expected to exceed $500,000. In addition, the servicer has
          determined that under certain circumstances, the servicer's
          automated loan servicing system calculates the applicable interest
          to be used to determine prepayment premiums inconsistently with the
          requirements of certain mortgage loan notes, which could result in
          the underpayment of prepayment premiums due to certificateholders in
          prepayment premium classes under the terms of the applicable
          transaction agreements. Approximately 15 loans in 8 securitizations
          subject to Regulation AB have been identified that may have been
          affected in 2007. Any amounts due as the result of these
          miscalculations will be delivered to the applicable Trustee for
          distribution to the affected investors once analysis of these
          matters has been completed and the amounts due in the case of each
          securitization have been determined. Processes and procedures are
          currently being implemented to provide for more accurate calculation
          of prepayment fees and the servicer is making changes to its
          automated servicing system to provide for some of the identified
          variations in the terms of mortgage note prepayment requirements;

      d.  Item 1122(d)(4)(vii). With respect to 4 series of mortgage-backed
          securities, the servicer recently self-identified foreclosure cases
          initiated in connection with approximately 175 loans where the
          servicer did not expressly disclose the interests in the loans of
          the applicable trustees. To the extent necessary under applicable
          law and court rules, the servicer will promptly move to amend those
          foreclosure pleadings. Investors will be made whole if any direct
          losses or additional costs and expenses are incurred as a result of
          the failure to identify the interests of the trusts in the loans in
          any proceeding in which applicable law or court rules the trusts'
          interests must be disclosed. The servicer will conduct further
          research and if additional loans are identified that were treated
          similarly, the servicer will make the applicable trusts whole if any
          losses arise from such treatment; and

      e.  Item 1122(d)(4)(xiv). Delinquent second lien mortgage loans were not
          charged off at 180 days as required by the applicable pooling and
          servicing agreements in the case of two securitizations subject to
          Reg AB. All such mortgage loans were charged off as required upon
          identification of the non-compliance. Processes and procedures have
          been put in place to provide for on-going compliance with this
          requirement.
