      ITEM 1112(B) OF REGULATION AB. SIGNIFICANT OBLIGORS OF POOL ASSETS
      (FINANCIAL INFORMATION).

      None.

      ITEM 1114(B)(2) OF REGULATION AB: CREDIT ENHANCEMENT AND OTHER
      SUPPORT, EXCEPT FOR CERTAIN DERIVATIVES INSTRUMENTS (FINANCIAL
      INFORMATION).

      None.

      ITEM 1115(B) OF REGULATION AB: CERTAIN DERIVATIVES INSTRUMENTS
      (FINANCIAL INFORMATION).

      Based on the  standards  set forth in Item  1115(b) of  Regulation  AB, no
      information is required in response to this Item.

      ITEM 1117 OF REGULATION AB: LEGAL PROCEEDINGS.

      There are no material  pending  legal or other  proceedings  involving the
      mortgage  loans  or  Residential   Funding  Company,   LLC   ("Residential
      Funding"),  as sponsor and master  servicer,  Residential  Asset  Mortgage
      Products, Inc., as depositor,  RAMP Series 2006-EFC1 Trust, as the issuing
      entity,  Homecomings Financial,  LLC ("Homecomings"),  as subservicer,  or
      other parties  described in Item 1117 of Regulation AB that,  individually
      or in the aggregate,  would have a material adverse impact on investors in
      the securities (the "Securities") to which this report relates.


<PAGE>

      Residential Funding and Homecomings are currently parties to various legal
      proceedings  arising  from  time to time in the  ordinary  course of their
      businesses,   some  of  which  purport  to  be  class  actions.  Based  on
      information currently available,  it is the opinion of Residential Funding
      and Homecomings that the eventual  outcome of any currently  pending legal
      proceeding,  individually  or in the  aggregate,  will not have a material
      adverse  effect on their ability to perform their  obligations in relation
      to the mortgage loans. No assurance,  however, can be given that the final
      outcome of these legal proceedings, if unfavorable, either individually or
      in the aggregate,  would not have a material adverse impact on Residential
      Funding or  Homecomings.  Any such  unfavorable  outcome  could  adversely
      affect the ability of  Residential  Funding or  Homecomings to perform its
      servicing  duties with respect to the mortgage loans and potentially  lead
      to the replacement of Residential  Funding or Homecomings with a successor
      servicer.

      TO FORM 10-K:

      ITEM 1119 OF REGULATION AB:  AFFILIATIONS AND CERTAIN RELATIONSHIPS
      AND RELATED TRANSACTIONS.

      Information  contemplated  by Item 1119 of  Regulation AB has been omitted
      from this report in reliance on the Instruction to Item 1119.

      ITEM 1122 OF REGULATION AB: COMPLIANCE WITH APPLICABLE SERVICING
      CRITERIA.

      Each of Residential Funding Company, LLC, Homecomings Financial, LLC, U.S.
      Bank  National  Association  and Wells  Fargo Bank,  National  Association
      (each, a "Servicing Participant") has been identified by the registrant as
      a party  participating in the servicing  function with respect to the pool
      assets  held  by  the  Issuing  Entity.  Each  Servicing  Participant  has
      completed  a report on an  assessment  of  compliance  with the  servicing
      criteria  applicable to such  Servicing  Participant  (each,  a "Report on
      Assessment")  as of December  31, 2006 and for the period  covered by this
      Form 10-K,  which Reports on  Assessment  are attached as exhibits to this
      Form 10-K.  In  addition,  each  Servicing  Participant  has  provided  an
      attestation  report  (each,  an  "Attestation  Report")  by  a  registered
      independent  public  accounting  firm  regarding  its  related  Report  on
      Assessment. Each Attestation Report is attached as an exhibit to this Form
      10-K.

      A Servicing Participant may engage one or more vendors to perform specific
      and limited,  or scripted  activities that address all or a portion of one
      or more servicing criteria  applicable to such Servicing  Participant.  In
      these  cases,  the  Servicing  Participant  has  instituted  policies  and
      procedures  to monitor  whether  such  vendors'  activities  comply in all
      material  respects  with such  servicing  criteria,  and may elect to take
      responsibility  for  assessing  compliance  with  the  servicing  criteria
      applicable to such vendors'  activities  in such  Servicing  Participant's
      Report on Assessment.

      Except as disclosed below, no Report on Assessment or related  Attestation
      Report has identified (i) any material instance of noncompliance  with the
      servicing  criteria  identified in such Report on Assessment as applicable
      to the related  Servicing  Participant or (ii) any material  deficiency in
      such  Servicing  Participant's  policies and  procedures to monitor vendor
      compliance.

      Exceptions:

      Residential  Funding  Company,  LLC: The Report on Assessment  prepared by
      Residential  Funding Company,  LLC and the related Attestation Report have
      identified material  noncompliance with one servicing criterion applicable
      to it. Specifically,  with regard to servicing criterion  1122(d)(3)(i)(B)
      (which   contemplates  that  reports  to  investors  provide   information
      calculated  in  accordance  with the terms  specified  in the  transaction
      agreements),  information  required  by  the  transaction  agreements  was
      excluded  from,  or  incorrectly  reported  in,  certain  of the  investor
      reports.  The registrant does not believe these  reporting  errors had any
      material  impacts  or  effects  on  investors  and  corrective  action was
      completed to address ongoing compliance.


<PAGE>

      Platform-Level Reports:

      Regulations of the Securities and Exchange  Commission (the "SEC") require
      that each  Servicing  Participant  complete  a Report on  Assessment  at a
      "platform" level,  meaning that the transactions  covered by the Report on
      Assessment  should  include  all  asset-backed   securities   transactions
      involving  such  Servicing  Participant  that are backed by the same asset
      type.  More  recent  guidance  from the SEC  staff  identifies  additional
      parameters  which a Servicing  Participant may apply to define and further
      limit its platform.  For example,  a Servicing  Participant may define its
      platform to include  only  transactions  that were  completed  on or after
      January  1, 2006 and that were  registered  with the SEC  pursuant  to the
      Securities  Act of 1933.  Each Servicing  Participant  is responsible  for
      defining its own platform,  and each platform will naturally  differ based
      on various factors,  including the Servicing  Participant's business model
      and the transactions in which it is involved.

      Based on our  understanding  of their  platforms  and the guidance that is
      available  at this  time,  we  believe  that the  parameters  by which the
      Servicing Participants have defined their platforms should be permissible.
      However,  because the SEC's  regulations  are new and the guidance that is
      available at this time is subject to  clarification  or change,  we cannot
      assure you that the SEC and its staff will necessarily agree.

      ITEM 1123 OF REGULATION AB: SERVICER COMPLIANCE STATEMENT.

      Each of Residential Funding Company,  LLC and Homecomings  Financial,  LLC
      (each, a "Servicer")  has been  identified by the registrant as a servicer
      with respect to the pool assets held by the Issuing Entity.  Each Servicer
      has  provided a statement of  compliance  with its  obligations  under the
      servicing agreement applicable to such Servicer (a "Compliance Statement")
      for the  period  covered  by this Form  10-K,  in each  case  signed by an
      authorized officer of the related servicer.
       Each  Compliance  Statement  is attached as an exhibit to this Form 10-K.
      None of the  Compliance  Statements  has identified any instance where the
      related  Servicer  has  failed  to  fulfill  its  obligations   under  the
      applicable servicing agreement in any material respects.


                                      PART IV

      ITEM 15.    EXHIBITS, FINANCIAL STATEMENT SCHEDULES.

            (a)(1) Not Applicable.

            (a)(2) Not Applicable.

            (a)(3) Not Applicable.
