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 Accredit Loans, Inc., as depositor, RALI Series
2006-QO8   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,  Deutsche  Bank Trust  Company  Americas  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, GMAC Mortgage,  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
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.
