Exhibit 33.4

[CLAYTON LOGO]

      Certification Regarding Compliance with Applicable Servicing Criteria

1.   Clayton Fixed Income Services Inc. ("CFIS") is responsible for assessing
     compliance with the servicing criteria applicable to it under paragraph (d)
     of Item 1122 of Regulation AB, as of and for the 12-month period ending
     December 31, 2006 (the "Reporting Period"). The transactions covered by
     this report include mortgage-backed securities transactions (each, a
     "Trust") for which CFIS acted as credit risk manager (the "Platform"),
     including: FFMLT 2006-FF16; Soundview 2006-WF1; and Soundview 2006-WF2.

2.   The criteria listed in the column titled "Performed by CFIS" in Appendix A
     are those criteria applicable (in part) to the Platform under paragraph (d)
     of 1122 of Regulation AB and are those criteria for which this
     certification is required pursuant to the terms and conditions of the
     various trust agreements and/or pooling and servicing agreements (the
     "Transaction Documents") through which CFIS was retained to act as credit
     risk manager;

3.   CFIS can only certify compliance with sub-parts (A) and (B) of the criteria
     set forth in 1122(d)(3)(i) because sub-parts (C) and (D) are not within the
     scope of services CFIS has been retained to provide to the Trusts.

     A.   With respect to subparts (A) and (B) of 1122(d)(3)(i), management
          identified certain instances where component sections specified in the
          Transaction Documents were not included in a given month's credit risk
          manager report. These instances related to one of the following: (i) a
          loss analysis was not included; (ii) a mortgage insurance analysis was
          not included; or (iii) the standard default assumption (SDA) analytic
          was not included. Management believes that items (i), (ii), and (iii)
          above occurred for the following reasons, respectively: (i) the
          relevant Trust had not incurred any losses as of the date of the
          report; (ii) the relevant Trust did not have a mortgage insurance
          policy or there had been no mortgage insurance activity as of the date
          of the report; and (iii) there was insufficient or statistically
          insignificant data available to generate the applicable analytic
          component.

     B.   With respect to subpart (C) of 1122(d)(3)(i), CFIS is not required to
          file its reports with Securities Exchange Commission; per the
          Transaction Documents, the CFIS reports are to be included in the
          monthly filing responsibility for filing with the Commission rests
          with a party other than CFIS. Accordingly, the certification contained
          herein with respect to the Platform applies only to CFIS delivering
          its reports to the applicable third party responsible for including
          CFIS' reports with the Commission in accordance with the Commission's
          rules and regulations.

     C.   With respect to subpart (D) of 1122(d)(3)(i), CFIS is not responsible
          for ensuring that its reports "agree with investors' or the trustee's
          records as to the total unpaid principal balance and number of pool
          assets serviced by the Servicer." CFIS' role (in part) in the
          transactions in which it is retained is to provide oversight functions
          with respect to the servicers in such transactions and to identify
          issues in the areas of collateral reporting. In connection with such
          role, CFIS would report on discrepancies between the balance and
          number of pool assets as reported by the various transaction
          fiduciaries.

4.   Those criteria listed in the column "Inapplicable Servicing Criteria" on
     Appendix A hereto are inapplicable to CFIS based on the activities it
     performs with respect to the Platform;

5.   Subject to the foregoing, CIFS has complied, in all material respects, with
     the applicable servicing criteria as of December 31, 2006 and for the
     Reporting Period with respect to the Platform taken as a whole;

6.   Hein & Associates, a registered public accounting firm, has issued an
     attestation report on CFIS' assessment of compliance with the applicable
     servicing criteria for the Reporting Period. Such report is attached
