INFORMATION).

Based  on the  standards  set  forth  in  Item  1115(b)  of  Regulation  AB,  no

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,
RAAC Series 2006-SP4 Trust, as the issuing entity,  Homecomings  Financial,  LLC
("Homecomings")  and GMAC Mortgage,  LLC ("GMACM"),  as  subservicers,  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,  Homecomings  and GMACM 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,  Homecomings and
GMACM 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, Homecomings or GMACM. Any
such  unfavorable  outcome  could  adversely  affect the ability of  Residential
Funding,  Homecomings  or GMACM to perform its servicing  duties with respect to
the  mortgage  loans and  potentially  lead to the  replacement  of  Residential
Funding, Homecomings or GMACM with a successor servicer.

SUBSTITUTE INFORMATION PROVIDED IN ACCORDANCE WITH GENERAL INSTRUCTION J 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, GMAC  Mortgage,  LLC,  Homecomings
Financial,   LLC,  Litton  Loan  Servicing,  LP,  Wilshire  Credit  Corporation,
LandAmerica  Tax and Flood Services,  Inc.,  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 general 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.   Where  the  Servicing
Participant  has not  instituted  such  policies  and  procedures,  or where the
Servicing  Participant  does  not  otherwise  elect to take  responsibility  for
assessing its vendors'  activities,  the vendor is itself treated as a Servicing
Participant  and is required to provide its own Report on Assessment and related
Attestation Report.

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.
Litton  Loan  Servicing  LP: The Report on  Assessment  prepared  by Litton Loan
Servicing LP ("LLS") and the related Attestation Report have identified material
instances  of  noncompliance  with  two  servicing  criteria  applicable  to it.
Specifically -


<PAGE>

   o  With regard to servicing criterion 1122(d)(2)(vii)(D),  which contemplates
      that  reconciliations are prepared on a monthly basis for all asset-backed
      securities   related   bank   accounts,   LLS's   investor   bank  account
      reconciliations  included certain reconciling items that were not resolved
      within  90  calendar  days of their  original  identification  on 11 of 63
      investor bank account reconciliations  selected for testing. LLS indicates
      that the sum of the  reconciling  items for those 11  reconciliations  was
      $216,950.

   o  With regard to servicing criterion 1122(d)(4)(ix), which contemplates that
      adjustments  to  interest  rates on pool assets  with  variable  rates are
      computed  in  accordance  with the  related  pool asset  documents,  LLS's
      testing of 65 adjustable rate mortgages revealed 2 instances where certain
      adjustable  rate  mortgages  for  which  the  interest  rate  reset in the
      servicing system did not agree to interest rates in the appropriate source
      index  per  the  borrower's  note  documents.  LLS  indicates  that  these
      instances  were the result of incorrect  information  transferring  from a
      prior servicer. LLS also indicates that the same 65 mortgages selected for
      testing  included 1 instance  where the adjustable  rate mortgage  payment
      change date in the servicing system did not agree to the loan documents.

In addition,  the Compliance Statement prepared by LLS (see the discussion below
under "Item 1123 of Regulation AB: Servicer  Compliance  Statement")  identifies
instances of noncompliance with one additional servicing criterion applicable to
it. Specifically -

   o  With regard to servicing  criterion  1122(d)(4)(vii),  which  contemplates
      that records  documenting  collection  efforts are  maintained  during the
      period a pool  asset is  delinquent  in  accordance  with the  transaction
      agreements,  LLS's  testing  disclosed 2 instances  for which there was no
      evidence that approvals  required under the  applicable  master  servicing
      guide were obtained for repayment plans that were longer than 12 months.


Wilshire  Credit  Corporation:  The Report on  Assessment  prepared  by Wilshire
Credit  Corporation  ("WCC") and the related  Attestation Report have identified
material   noncompliance  with  one  servicing   criterion   applicable  to  it.
Specifically,   with  regard  to  servicing  criterion   1122(d)(4)(iv),   which
contemplates  that payments on pool assets are  administered  in accordance with
the transaction  agreements,  WCC's testing  revealed that, for 1 of the 45 loan
payoffs selected for testing, WCC charged a prepayment charge to a borrower that
was not in accordance  with the related  mortgage  note.  WCC indicates  that it
calculated the prepayment  charge in accordance with the related  mortgage note,
but transposed the numbers when entering the charge into WCC's system, resulting
in an  overcharge to the borrower.  WCC also  indicates  that the error has been
corrected  and  the  overcharge  was  refunded  to the  borrower.  We  have  not
independently  verified the accuracy of WCC's  assertions or the adequacy of its
remediation efforts.


<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, GMAC  Mortgage,  LLC,  Homecomings
Financial, LLC, Litton Loan Servicing, LP and Wilshire Credit Corporation (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.

Except as disclosed  below, no Compliance  Statement has identified any instance
where the  related  Servicer  has failed to fulfill  its  obligations  under the
applicable servicing agreement in any material respect.

Exceptions:

Litton  Loan  Servicing  LP: The  Compliance  Statement  prepared by Litton Loan
Servicing LP identifies the same  exceptions as its exceptions  described  above
under  "Item  1122  of  Regulation  AB:  Compliance  with  Applicable  Servicing
Criteria."
