                   receipt, or such other number of days
                   specified in the transaction agreements,
                   and allocated to principal, interest or
                   other items (e.g., escrow) in accordance
                   with the related pool asset documents.

1122(d)(4)(v)      The Servicer's records regarding the              X
                   pool assets agree with the Servicer's
                   records with respect to an obligor's

1122(d)(4)(vi)     Changes with respect to the terms or              X
                   status of an obligor's pool assets (e.g.,
                   loan modifications or re-agings) are
                   made, reviewed and approved by authorized
                   personnel in accordance with the
                   transaction agreements and related pool
                   asset documents.

                   foreclosures and repossessions, as
                   applicable) are initiated, conducted and

                   the timeframes or other requirements
                   established by the transaction

1122(d)(4)(viii)   Records documenting collection efforts            X
                   are maintained during the period a pool

                   the transaction agreements. Such records
                   are maintained on at least a monthly
                   basis, or such other period specified in
                   the transaction agreements, and describe
                   the entity's activities in monitoring
                   delinquent pool assets including, for
                   example, phone calls, letters and
                   payment rescheduling plans in cases where
                   delinquency is deemed temporary (e.g.,
                   illness or unemployment).

1122(d)(4)(ix)     Adjustments to interest rates or rates            X
                   of return for pool assets with variable
                   rates are computed based on the related
                   pool asset documents.

1122(d)(4)(x)      Regarding any funds held in trust for             X
                   an obligor (such as escrow accounts): (A)
                   such funds are analyzed, in accordance

                   on at least an annual basis, or such
                   other period specified in the transaction
                   agreements; (B) interest on such funds is
                   paid, or credited, to obligors in
                   accordance with applicable pool asset
                   documents and state laws; and (C) such
                   funds are returned to the obligor within
                   30 calendar days of full repayment of the
                   related pool assets, or such other number
                   of days specified in the transaction
                   agreements.

1122(d)(4)(xi)     Payments made on behalf of an obligor             X                                 X
                   (such as tax or insurance payments) are

                   appropriate bills or notices for such
                   payments, provided that such support has
                   been received by the Servicer at least 30
                   calendar days prior to these dates, or
                   such other number of days specified in

                   behalf of an obligor are paid from the
                   Servicer's funds and not charged to the

1 No transaction agreements require the Asserting Party to maintain a back-up servicer.

2 The Asserting Party performs the servicing functions described in Items 1122(d)(3)(i)(A) and (B). With regard to section (D) of
  criteria (3)(i), it is not the Asserting Party's practice to regularly tie-out balances to investors' or trustee's records. Loan
  counts and balances are periodically reconciled upon request by a master servicer.

3 The Asserting Party does not perform the servicing function described in Item 1122(d)(3)(i)(C).

APPENDIX B


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;


(page)


    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.
