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.

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.
