         Pursuant to a Form 8-K filed on March 28, 2007 (the "March 28th
Announcement"), on March 26, 2007 New Century, the parent of Home123 Corporation
("Home123"), one of the original loan sellers, notified the Federal Home Loan
Mortgage Corp. ("Freddie Mac"), that it was voluntarily terminating its
eligibility with Freddie Mac. As a result of this termination, New Century and
its subsidiaries are no longer able to sell mortgage loans directly to Freddie
Mac or act as the primary servicer of any mortgage loans for Freddie Mac.

         According to the March 28th Announcement several of New Century's
lenders have notified New Century of their intent to sell the outstanding
mortgage loans that have been financed by the respective lender and offset the
proceeds from such sale against the New Century's obligations to the lender,
while reserving their rights to seek recovery of any remaining deficiency from
New Century. New Century has notified these lenders of its concerns that any
such sale be conducted in an appropriate manner, in accordance with applicable
law and in accordance with the terms of the applicable financing agreement
between the parties.

         Pursuant to a Form 8-K filed on March 22, 2007 (the "March 22nd
Announcement"), New Century stated that it had previously announced that it had
received notices from Barclays Bank PLC ("Barclays"), in which Barclays alleged
that certain events of default had occurred, as defined in that certain Master
Repurchase Agreement, dated as of March 31, 2006 (as amended to date), by and
among New Century, certain of New Century's subsidiaries, Barclays and Sheffield
Receivables Corporation (the "Barclays Agreement"), and purported to accelerate
to March 14, 2007 the obligation of New Century's subsidiaries to repurchase all
outstanding mortgage loans financed under the Barclays Agreement and to
terminate the Barclays Agreement as of that same date. New Century estimated
that the aggregate repurchase obligation (the outstanding mortgage loans
financed) of its subsidiaries under the Barclays Agreement was approximately
$0.9 billion as of March 12, 2007.

         According to the March 22nd Announcement, on March 16, 2007, the
parties to the Barclays Agreement entered into a letter agreement (the "Barclays
Letter Agreement") pursuant to which Barclays and Sheffield Receivables
Corporation agreed to release New Century and its subsidiaries from its
aggregate repurchase obligation under the Barclays Agreement and New Century and
its subsidiaries agreed to release their rights to outstanding mortgage loans
that had been financed under the Barclays Agreement. The effectiveness of the
releases in the Barclays Letter Agreement is subject to the satisfaction of
certain preconditions, including that (i) New Century and its subsidiaries shall
have made certain payments to Barclays, including forwarding to Barclays all
amounts received by New Century and its subsidiaries after March 1, 2007 with
respect to the mortgage loans under the Barclays Agreement, and (ii) New Century
and its subsidiaries shall have taken certain actions to facilitate the transfer
of the servicing function with respect to the mortgage loans under the Barclays
Agreement to a third party appointed by Barclays. As of March 22, 2007, New
Century was still in the process of satisfying these preconditions.

         According to the March 22nd Announcement, the Barclays Letter Agreement
provides that the outstanding mortgage loans financed under the Barclays
Agreement are being transferred to Barclays "as is", without any representations
or warranties by New Century or its subsidiaries, and without any holdback by
Barclays. New Century and its subsidiaries have agreed, however, that if they
enter into a settlement or release with any of New Century's other lenders and
any such release contains materially more favorable terms for the benefit of any
such lender than those in the Barclays Letter Agreement, then Barclays will be
entitled to such more favorable terms. For purposes of this provision, the
Barclays Letter Agreement provides that a release with another lender will not
be deemed to have terms that are materially more favorable to that lender from
an economic standpoint if the terms of such release do not provide for more to
such lender than the amount of the outstanding mortgage loans financed by such
lender, plus accrued price differential or interest and the transmittal of the
principal portion of any loan payments received. The continuing effectiveness of
the release by Barclays under the Barclays Letter Agreement is subject to New
Century's compliance with this provision. Upon the effectiveness of the releases
contemplated by the Barclays Letter Agreement, the aggregate repurchase
obligation (the outstanding mortgage loans financed) of New Century under its
credit facilities will be reduced by approximately $0.9 billion and New Century
will have realized a loss from this transaction of approximately $46 million.

         Pursuant to a Form 8-K filed on March 20, 2007 (the "March 20th
Announcement"), New Century stated that it received a Notice of Breach and
Termination of Mortgage Selling and Servicing Contract, dated March 14, 2007,
from the Federal National Mortgage Association ("Fannie Mae"). In its notice,
Fannie Mae purports to terminate its mortgage selling and servicing contract
(the "Fannie Mae Contract") with New Century Mortgage Corporation ("NCMC"), a
subsidiary of New Century, for cause, based on alleged breaches of the Fannie
Mae Contract as well as alleged breaches by NCMC under other contracts with
Fannie Mae. As a result of the purported termination, New Century and its
subsidiaries are no longer able to sell mortgage loans directly to Fannie Mae or
act as the primary servicer of any mortgage loans for Fannie Mae.

         Pursuant to a Form 8-K filed on March 14, 2007 (the "March 14th
Announcement"), New Century stated that the staff of the New York Stock Exchange
("NYSE") issued a press release, dated March 13, 2007, announcing its
determination that New Century's common stock is no longer suitable for
continued listing on the NYSE and will be suspended immediately. New Century
announced that the NYSE's press release cited New Century's recent disclosures
regarding its liquidity position, as well as New Century's prior announcement
regarding the need to restate certain of its historical financial statements, in
support of its determination that New Century's common stock and preferred stock
are no longer suitable for continued listing on the NYSE.

         In addition, according to the March 14th Announcement, New Century
announced that the NYSE's press release also stated that an application to the
SEC to delist New Century's stock from the NYSE is pending the completion of the
applicable procedures, including any appeal by New Century of the NYSE staff's
decision. New Century stated that it is reviewing the NYSE staff's decision and
accordingly has not yet determined whether it will appeal the staff's decision
to delist New Century's stock.

         Pursuant to a Form 8-K/A filed on March 13, 2007 (the "March 13th Form
8-K/A Announcement") by New Century, New Century stated that as of March 9,
2007, all of New Century's lenders under its short-term repurchase agreements
and aggregation credit facilities had discontinued their financing with New
Century or had notified New Century of their intent to do so. It further stated
in the March 13th Form 8-K/A Announcement that New Century has received notices
from certain of its lenders asserting that New Century and/or its subsidiaries
have violated their respective obligations under certain of these financing
arrangements and that such violations amount to events of default. According to
the March 13th Form 8-K/A Announcement, certain of these lenders have further
advised New Century that they are accelerating New Century's obligation to
repurchase all outstanding mortgage loans financed under the applicable
agreements.

         Pursuant to a Form 8-K filed on March 8, 2007 by New Century, New
Century stated that as a result of its current constrained funding capacity, New
Century has elected to cease accepting loan applications from prospective
borrowers effective immediately while New Century seeks to obtain additional
funding capacity.

         New Century also announced that it was delaying the filing of its
Annual Report on Form 10-K for the fiscal year ended December 31, 2006.

         New Century announced that, although a full review is ongoing, it
expects that the modifications to the allowance for loan repurchase losses will
result in restated net income for the first three quarters of 2006 that is
significantly lower than previously reported in New Century's 2006 interim
financial statements.

         In addition, New Century announced that although New Century's mortgage
loan origination volume increased in 2006 when compared to 2005, New Century's
results of operations for the quarter and year ended December 31, 2006 will
reflect declines in earnings and profitability when compared to the same periods
in 2005. New Century currently expects that it will report a pretax loss for
both the fourth quarter and the full year ended December 31, 2006.

         According to the March 2nd Announcement, New Century relies on its 15
short-term repurchase agreements and aggregation credit facilities and an
asset-backed commercial paper facility that collectively provide New Century
with an aggregate of approximately $13.0 billion of committed and $4.4 billion
of uncommitted borrowing capacity to fund mortgage loan originations and
purchases pending the pooling and sale of such mortgage loans.

         According to the March 2nd Announcement, in the event New Century is
unable to obtain satisfactory amendments to and/or waivers of the covenants in
its financing arrangements from a sufficient number of its lenders, or obtain
alternative funding sources, New Century's auditor, KPMG, has informed New
Century's Audit Committee that its report on New Century's financial statements
will include an explanatory paragraph indicating that substantial doubt exists
as to New Century's ability to continue as a going concern.

Item 1117 of Regulation AB:  Legal Proceedings

     On April 2, 2007, New Century  Financial  Corporation  filed for Chapter 11
bankruptcy in U.S. Bankruptcy Court for the District of Delaware.

     Pursuant  to  a  Form  8-K  filed  on  March  28,  2007  (the  "March  28th
Announcement"),  on March 27, 2007, New Century,  the parent of Home123,  one of
the original loan sellers,  announced that it had signed consent agreements with
the State of Idaho's Department of Finance,  the State of Iowa's  Superintendent
of Banking,  the State of Michigan's Office of Financial and Insurance  Services
and the  State of  Wyoming's  Banking  Commissioner  (the  "March  27th  Consent
Agreements").  Although New Century has signed the March 27th Consent Agreements
and  expects to comply  with  their  terms,  New  Century  has not yet  received
counterpart  signatures from the respective  states and  accordingly  such March
27th Consent  Agreements may not be binding on the respective  states. The March
27th  Consent  Agreements  contain  allegations  that  certain of New  Century's
subsidiaries  have engaged in  violations of state law,  including,  among other
things,  failure to fund mortgage  loans after  closing.  The March 27th Consent
Agreements  restrain New Century's  subsidiaries  from taking  certain  actions,
including,  among other things,  engaging in alleged violations of state law and
taking new applications for mortgage loans in the relevant jurisdiction.

         In addition, according to the March 28th Announcement, the March 27th
Consent Agreements also compel New Century's subsidiaries to affirmatively take
certain actions, including the creation of escrow accounts to hold any up front
fees collected in connection with pending mortgage applications, the transfer to
other lenders of the outstanding mortgage applications and unfunded mortgage
loans held by the subsidiaries, and the provision of regular information to the
state regulators regarding the subsidiaries' activities in the applicable state,
including the status of all outstanding mortgage applications and unfunded
mortgage loans in that state.

         According to the March 28th Announcement, New Century anticipates that
cease and desist orders will continue to be received by New Century and its
subsidiaries from additional states in the future and that New Century and its
subsidiaries may enter into additional consent agreements similar to the consent
agreements already entered into by New Century. New Century stated that it
intends to continue to cooperate with its regulators in order to mitigate the
impact on consumers resulting from New Century's funding constraints.

         Pursuant to a Form 8-K filed on March 22, 2007 (the "March 22nd
Announcement"), New Century has received cease and desist orders from several
states and entered into consent agreements with several states (the "Previous
Orders and Consent Agreements"). On March 20, 2007, certain of New Century's
subsidiaries entered into a consent agreement with the State of Maine's Office
of Consumer Credit Regulation, respectively (the "March 20 Consent Agreement").

         According to the March 22nd Announcement, consistent with the Previous
Orders and Consent Agreements, the March 20 Consent Agreement contains
allegations that certain of New Century's subsidiaries have engaged in
violations of state law, including, among other things, failure to fund mortgage
loans after closing. Consistent with the Previous Orders and Consent Agreements,
the March 20 Consent Agreement seeks to restrain New Century's subsidiaries from
taking certain actions, including, among others, engaging in alleged violations
of state law and taking new applications for mortgage loans in the relevant
jurisdiction. The March 20 Consent Agreement also seeks to cause the
subsidiaries to affirmatively take certain actions, including the creation of
escrow accounts to hold fees relating to pending mortgage applications, the
transfer to other lenders of the outstanding mortgage applications and unfunded
mortgage loans held by the subsidiaries, and the provision of regular
information to the state regulators regarding the subsidiaries' activities in
the applicable state, including the status of all outstanding mortgage
applications and unfunded mortgage loans in that state.

         Pursuant to a Form 8-K filed on March 20, 2007 (the "March 20th
Announcement"), on March 16, 2007, New Century received additional cease and
desist orders from the State of California (the "California Orders") and certain
of New Century's subsidiaries entered into consent agreements with the State of
Florida's Office of Financial Regulation and the State of Washington's
Department of Financial Institutions, respectively, each dated March 16, 2007
(the "March 16 Agreements") and together with the California Orders, the "March
16 Orders and Consent Agreements").

         According to the March 20th Announcement, consistent with certain other
previous consent agreements, the March 16 Orders and Consent Agreements contain
allegations that certain of New Century's subsidiaries have engaged in
violations of state law, including, among other things, failure to fund mortgage
loans after closing. Consistent with certain other previous consent agreements,
the March 16 Orders and Consent Agreements seek to restrain New Century's
subsidiaries from taking certain actions, including, among other things,
engaging in alleged violations of state law and taking new applications for
mortgage loans in the relevant jurisdiction. New Century announced that the
March 16 Orders and Consent Agreements also seek to cause the subsidiaries to
affirmatively take certain actions, including the creation of escrow accounts to
hold fees relating to pending mortgage applications, the transfer to other
lenders of the outstanding mortgage applications and unfunded mortgage loans
held by the subsidiaries, and the provision of regular information to the state
regulators regarding the subsidiaries' activities in the applicable state,
including the status of all outstanding mortgage applications and unfunded
mortgage loans in that state. The California Orders become permanent if not
promptly appealed by the applicable subsidiaries. New Century and its
subsidiaries are reviewing the California Orders and accordingly have not yet
determined whether they will appeal all or any portion of the California Orders.

         Pursuant to a Form 8-K filed on March 19, 2007 (the "March 19th
Announcement"), New Century stated that on March 14, 2007 and March 15, 2007, it
received additional cease and desist orders from the States of Connecticut,
Maryland, Rhode Island and Tennessee (collectively, the "March 14-15 Orders").
New Century stated that the cease and desist orders contain allegations that
certain of New Century's subsidiaries have engaged in violations of applicable
state law, including, among other things and failure to fund mortgage loans
after a mortgage closing. Additionally, on March 14, 2007, certain of New
Century's subsidiaries, entered into a Consent Agreement and Order, dated March
14, 2007, with the Commonwealth of Pennsylvania Department of Banking, Bureau of
Supervision and Enforcement (the "Consent Agreement").

         The March 14-15 Orders and the Consent Agreement seek to restrain New
Century's subsidiaries from taking certain actions, including, among others,
engaging in alleged violations of applicable state law and taking new
applications for mortgage loans in the relevant jurisdiction. The March 14-15
Orders and the Consent Agreement also seek to cause the subsidiaries to
affirmatively take certain actions, including the creation of escrow accounts to
hold fees relating to pending mortgage applications, the transfer to other
lenders of the outstanding mortgage applications and unfunded mortgage loans
held by the subsidiaries, and the provision of regular information to the state
regulators regarding the subsidiaries' activities in the applicable state,
including the status of all outstanding mortgage applications and unfunded
mortgage loans in that state. Certain of the March 14-15 Orders also seek to
revoke the licenses of one or more of New Century's subsidiaries or assess
administrative penalties.

         The March 14-15 Orders generally become permanent if not promptly
appealed by the applicable subsidiaries. New Century and its subsidiaries are
reviewing the March 14-15 Orders and accordingly have not yet determined whether
they will appeal all or any portion of the March 14-15 Orders.

         According to the March 19th Announcement, on March 14, 2007, in
connection with a civil action filed against New Century and certain of its
subsidiaries in an Ohio state court (the "Ohio Complaint") by the Attorney
General of Ohio and the Ohio Division of Commerce, Division of Financial
Institutions, such Ohio state court issued a temporary restraining order, which
was subsequently modified by the court on March 16, 2007, against New Century
(as modified, the "Ohio TRO"). New Century stated that the Ohio Complaint and
the Ohio TRO contain allegations that New Century has engaged in violations of
applicable Ohio state law, including, among other things, failure to fund
mortgage loans after closing. New Century stated that the Ohio TRO restrains New
Century from taking certain actions, including, among other things, (i) engaging
in violations of Ohio state law, (ii) soliciting applicants and taking new
applications for mortgage loans in Ohio and (iii) initiating, prosecuting or
enforcing foreclosure actions in Ohio. New Century announced that the Ohio TRO
also requires New Century to confer with the Ohio Attorney General and Division
of Commerce by March 22, 2007 regarding the treatment of Ohio loans that are
more than 60 days delinquent and are held for sale. New Century stated that the
restraints imposed by the Ohio TRO could further harm New Century's business. In
addition, New Century announced that it is reviewing the Ohio Complaint and the
Ohio TRO and accordingly has not yet determined whether it will appeal all or
any portion of the Ohio TRO. Subject to its funding limitations, New Century
stated that it intends to comply with the Ohio TRO pending any appeal.

         According to the March 19th Announcement, New Century announced that it
anticipates that orders similar to those described above will be received by New
Century or its subsidiaries from additional states and that it intends to
continue to cooperate with its regulators in order to mitigate the impact on
consumers resulting from New Century's funding constraints.

         Pursuant to a Form 8-K filed on March 14, 2007 (the "March 14th
Announcement"), New Century has been engaged in recent ongoing discussions with
its state regulators regarding New Century's funding constraints and the impact
on consumers who are in various stages of the loan origination process with New
Century. New Century stated that it has advised these regulators that it has
ceased accepting loan applications and that as of March 14, 2007, New Century
and its subsidiaries are unable to fund any mortgage loans, including mortgage
loans for those consumers who were already in the loan origination process with
New Century.

         According to the March 14th Announcement, on March 13, 2007, New
Century and certain of its subsidiaries received cease and desist orders from
regulators in the States of Massachusetts, New Hampshire, New Jersey and New
York. New Century stated that the cease and desist orders contain allegations
that certain of New Century's subsidiaries have engaged in violations of
applicable state law, including, among others, failure to fund mortgage loans
after a mortgage closing, failure to meet certain financial requirements,
including net worth and available liquidity, and failure to timely notify the
state regulators of defaults and terminations under certain of its financing
arrangements.

         According to the March 14th Announcement, the cease and desist orders
seek to restrain the subsidiaries from taking certain actions, including, among
others, engaging in further violations of state law, taking new applications for
mortgage loans in the relevant jurisdiction, and paying dividends or bonuses to
officers, directors or shareholders of the applicable subsidiaries. In addition,
the cease and desist orders also seek to cause the subsidiaries to affirmatively
take certain actions, including the creation of escrow accounts to hold fees
relating to pending mortgage applications, the transfer to other lenders of the
outstanding mortgage applications and unfunded mortgage loans held by the
subsidiaries, and the provision of regular information to the state regulators
regarding the subsidiaries' activities in the applicable state, including the
status of all outstanding mortgage applications and unfunded mortgage loans in
that state. Furthermore, certain of the cease and desist orders also require one
or more of the subsidiaries to show cause why their license should not be
revoked or why administrative penalties should not be assessed.

         According to the March 14th Announcement, the cease and desist orders
generally become permanent if not promptly appealed by the applicable
subsidiaries. New Century stated that it is reviewing these orders and
accordingly has not yet determined whether it will appeal all or any portion of
any of the orders. New Century announced that, subject to its funding
limitations, it intends to comply with the orders pending any such appeal.

         According to the March 14th Announcement, New Century announced that it
anticipates that orders similar to those described above will be received by New
Century or its subsidiaries from additional states and that it intends to
continue to cooperate with its regulators in order to mitigate the impact on
consumers resulting from New Century's funding constraints.

         Pursuant to a Form 8-K filed on March 13, 2007 (the "March 13th
Announcement"), by New Century, New Century received a letter from the staff of
the Pacific Regional Office of the Securities Exchange Commission ("SEC") on
March 12, 2007, stating that the staff was conducting a preliminary
investigation involving New Century and requesting production of certain
documents. In addition, New Century stated that the staff of the SEC had also
previously requested a meeting with New Century to discuss the events leading up
to the announcement of the restatements and New Century intends to comply with
the SEC's request.

         In addition, New Century stated in the March 13th Announcement that, on
February 28, 2007, New Century received a letter from the United States
Attorney's Office for the Central District of California ("U.S. Attorney's
Office") indicating that it was conducting a criminal inquiry under the federal
securities laws in connection with trading in New Century's securities, as well
as accounting errors regarding New Century's allowance for repurchase losses.
New Century also stated that it has subsequently received a grand jury subpoena
requesting production of certain documents. New Century stated that it intends
to cooperate with the requests of the U.S. Attorney's Office.

         Pursuant to a Form 12b-25 filed on March 2, 2007 (the "March 2nd
Announcement") by New Century, New Century stated that it had previously
reported that it had been served with a complaint for a purported securities
class action and was aware of nine additional purported class action lawsuits
that had been filed against it and certain of its officers and directors
alleging certain violations of federal securities laws.

         New Century also stated that since that time, it has become aware of
four related derivative complaints against certain of its directors and
officers, making essentially the same allegations as the federal securities
cases relating to New Century's restatements. New Century stated that it
believes that the derivative cases have been or will be filed in Orange County
Superior Court, and that it anticipates that similar actions may be filed in the
future.

                     Rule 13a-14(d)/15d-14(d) Certification

     I, Michelle Gill, certify that:

1.   I have  reviewed  this  report  on Form 10-K and all  reports  on Form 10-D
     required  to be filed in respect of the  period  covered by this  report on
     Form 10-K of GSR Mortgage  Loan Trust  2006-4F (the  "Exchange Act periodic
     reports");

2.   Based on my knowledge, the Exchange Act periodic reports, taken as a whole,
     do not contain any untrue  statement of a material  fact or omit to state a
     material  fact  necessary  to make  the  statements  made,  in light of the
     circumstances  under which such  statements  were made, not misleading with
     respect to the period covered by this report;

3.   Based  on my  knowledge,  all  of the  distribution,  servicing  and  other
     information  required to be provided under Form 10-D for the period covered
     by this report is included in the Exchange Act periodic reports;

4.   Based on my knowledge  and the servicer  compliance  statements required in
     this report  under Item 1123 of  Regulation  AB, and except as disclosed in
     the  Exchange  Act  periodic  reports, the  Servicers have fulfilled  their
     obligations  under the  Servicing Agreements in all material respects.

5.   All of the reports on assessment of compliance with servicing  criteria for
     asset-backed securities and their related attestation reports on assessment
     of compliance with servicing criteria for asset-backed  securities required
     to be included in this report in accordance with Item 1122 of Regulation AB
     and Exchange  Act Rules 13a-18 and 15d-18 have been  included as an exhibit
     to this report,  except as otherwise disclosed in this report. Any material
     instances of noncompliance described in such reports have been disclosed in
     this report on Form 10-K.

     Although each servicing criterion required by Item 1122(d) of Regulation AB
     is addressed in one or more of the Assessments of Compliance with Servicing
     Criteria and related  Attestation  Reports  included with this report,  the
     Assessments of Compliance and related Attestation Report delivered by Avelo
     Mortgage,  L.L.C.,  Countrywide  Home Loans  Servicing  LP,  GMAC  Mortgage
     Corporation and GreenPoint Mortgage Funding,  Inc., did not address each of
     the servicing criteria that such Servicer was required to address under the
     terms of the related Servicing Agreement. The Servicers have not identified
     such failure to provide an Assessment and  Attestation for these items as a
     material failure to fulfill their  obligations  under the related servicing
     agreement in the Servicer's  Compliance  Statement provided under Item 1123
     of Regulation  AB,  because the  Servicers  assert that those items are not
     applicable to such Servicer.

     In giving the certifications above, I have reasonably relied on information
provided to me  by the  following unaffiliated  parties: the Trustee, the Master
Servicer and the Servicers.

                                 JPMorgan Chase

              Management's Report on Assessment of Compliance with
                          Applicable Servicing Criteria

     JPMorgan  Chase  Bank,  National  Association  (the  "Asserting  Party") is
responsible for assessing compliance as of September 30, 2006 and for the period
from January 1, 2006 through September 30, 2006 (the "Reporting  Period"),  with
the servicing  criteria set forth in Title 17, Section  229.1122 (d) of the Code
of Federal  Regulations  (the  "CFR"),  to the extent  required  by the  related
transaction   agreements  and  excluding  the  criteria  set  forth  in  17  CFR
229.1122(d)  (1)(ii)-(iv),  (2)(iii),  (2)(vi),  (4)(i)-(ii),  and (4)(iv)-(xiv)
which the Asserting  Party has concluded are not applicable to the activities it
performs with respect to the asset-backed securitization transactions covered by
this report (such  criteria,  after giving effect to the  exclusions  identified
above,  the  "Applicable  Servicing  Criteria").   This  report  covers  certain
asset-backed  securities  transactions  backed by  residential  mortgages,  home
equity loans, auto loans,  credit card receivables,  dealer floor plans,  retail
installment  contracts and manufactured housing contracts for which transactions
the  Asserting  Party  performs the  Applicable  Servicing  Criteria as trustee,

Securities  and Exchange  Commission  pursuant to the Securities Act of 1933, as
amended,  where the related asset-backed  securities were outstanding during the
reporting period (the "Platform"), as listed in Appendix A.

     The  Asserting  Party  has  (i)  used  the  criteria  set  forth  in 17 CFR
229.1122(d) to assess the compliance by the Asserting  Party with the Applicable
Servicing  Criteria for the Reporting Period and (ii) concluded that, other than
as identified on Appendix B, the Asserting  Party has complied,  in all material
respects,  with the Applicable  Servicing  Criteria as of September 30, 2006 and
for the Reporting Period with respect to the Platform, taken as a whole.

     PricewaterhouseCoopers  LLP, an independent  registered  public  accounting
firm,  has issued an  attestation  report  for the  Platform,  stating  that the
Asserting Party has complied with the Applicable Servicing Criteria,  except for
material  instances of non-compliance  identified on Appendix B, as of September
30, 2006 and for the Reporting Period.

                                 JPMorgan Chase

              Management's Report on Assessment of Compliance with
                          Applicable Servicing Criteria

     JPMorgan  Chase  Bank,  National  Association  (the  "Asserting  Party") is
responsible  for  assessing  compliance as of October 1, 2006 and for the period
from October 1, 2006 through  December 31, 2006 (the "Reporting  Period"),  with
the servicing  criteria set forth in Title 17, Section  229.1122 (d) of the Code
of Federal  Regulations  (the  "CFR"),  to the extent  required  by the  related
transaction  agreements  excluding the criteria set forth in 17 CFR  229.1122(d)
(1)(i)-(iv),  (2)(i)-(vi),  (3)(i)-(iv),  and  (4)(i)-(xv),  which the Asserting
Party has  concluded  are not  applicable  to the  activities  it performs  with
respect to the asset-backed  securitization  transactions covered by this report
(such  criteria,  after giving effect to the exclusions  identified  above,  the
"Applicable Servicing Criteria"). This report covers the asset-backed securities
transactions backed by residential  mortgages and home equity loans, auto loans,
credit cards, dealer floor plans, retail installment  contracts and manufactured
housing  contracts  for which  transactions  the  Asserting  Party  performs the
applicable  servicing  criteria,  that were  registered  with the Securities and
Exchange  Commission  pursuant to the Securities Act of 1933, as amended,  where

                                                                     Appendix I

                      MANAGEMENT'S ASSERTION OF COMPLIANCE

Management  of the Trust &  Securities  Services  department  of  Deutsche  Bank
National  Trust Company and Deutsche Bank Trust Company  Americas  (collectively
the  "Company")  is  responsible  for  assessing  compliance  with the servicing
criteria  set  forth  in  Item  1122(d)  of  Regulation  AB  promulgated  by the
Securities and Exchange Commission. Management has determined that the servicing
criteria are  applicable in regard to the  servicing  platform for the period as
follows:

Platform:  Publicly-issued (i.e., transaction-level reporting required under the
Securities  Exchange  Act  of  1934,  as  amended)  residential  mortgage-backed
securities and other asset-backed  securities issued on or after January 1, 2006
for which the Company  provides  trustee,  securities  administration  or paying
agent services,  excluding any publicly issued transactions  sponsored or issued
by any government sponsored entity (the "Platform").

Applicable  Servicing  Criteria:  All servicing criteria set forth Item 1122(d),
except   for   the   following   criteria:   1122(d)(2)(iii),    1122(d)(4)(iv),
1122(d)(4)(v), 1122(d)(vi), 1122(d)(4)(vii),  1122(d)(4)(viii),  1122(d)(4)(ix),
1122(d)(4)(x),    1122(d)(4)(xi),    1122(d)(4)(xii),    1122(d)(4)(xiii)    and
1122(d)(4)(xiv),  which  management  has  determined  are not  applicable to the
activities  the Company  performs with respect to the Platform (the  "Applicable
Servicing Criteria").

Period: Twelve months ended December 31, 2006 (the "Period").

Management's  interpretation  of Applicable  Servicing  Criteria:  The Company's
management has determined that servicing criteria  1122(d)(1)(iii) is applicable
only with respect to its continuing obligation to act as, or locate a, successor
servicer under the circumstances referred to in certain governing documents.  It
is management's  interpretation  that Deutsche Bank Trust Company America has no
other active back-up servicing responsibilities in regards to 1122(d)(1)(iii) as
of and for the Period.

Third  parties  classified  as  vendors:  With  respect  to  servicing  criteria
1122(d)(2)(i), 1122(d)(4)(i), and 1122(d)(4)(ii), management has engaged various
vendors to perform the  activities  required by these  servicing  criteria.  The
Company's  management  has  determined  that these vendors are not  considered a
"servicer"  as  defined  in Item  1101(j) of  Regulation  AB, and the  Company's
management has elected to take responsibility for assessing  compliance with the
servicing  criteria  applicable  to each vendor as permitted  by  Interpretation
17.06 of the SEC Division of Corporation  Finance  Manual of Publicly  Available
Telephone   Interpretations    ("Interpretation   17.06").   As   permitted   by
Interpretation  17.06,   management  has  asserted  that  it  has  policies  and
procedures in place to provide reasonable assurance that the vendor's activities
comply in all material respects with the servicing  criteria  applicable to each
vendor.  The Company's  management is solely responsible for determining that it
meets the SEC requirements to apply Interpretation 17.06 for vendors and related
criteria.

With respect to the Platform,  the Company's  management  provides the following
assertion of compliance with respect to the Applicable Servicing Criteria:

1.   The  Company's  management  is  responsible  for  assessing  the  Company's
     compliance with the Applicable Servicing Criteria as of and for the Period.

2.   The  Company's  management  has  assessed  compliance  with the  Applicable
     Servicing  Criteria,  including  servicing criteria for which compliance is
     determined based on Interpretation  17.06 as described above, as of and for
     the Period. In performing this assessment, management used the criteria set
     forth by the  Securities  and Exchange  Commission in paragraph (d) of Item
     1122 of Regulation AB.

3.   Based  on such  assessment,  as of and  for the  Period,  the  Company  has
     complied, in all material respects, with the Applicable Servicing Criteria.

KPMG LLP, a registered public accounting firm, has issued an attestation  report
with respect to the  management's  assertion of compliance  with the  Applicable
Servicing Criteria as of and for the Period.

                Management's Report on Assessment of Compliance
                       with Applicable Servicing Criteria

     JPMorgan  Chase  Bank,  National  Association  (the  "Asserting  Party") is
responsible for assessing compliance as of September 30, 2006 and for the period
from January 1, 2006 through September 30, 2006 (the "Reporting  Period"),  with
the servicing  criteria set forth in Title 17, Section  229.1122 (d) of the Code
of Federal  Regulations  (the  "CFR"),  to the extent  required  by the  related
transaction  agreements  excluding the criteria set forth in 17 CFR  229.1122(d)
(1)(i)-(iv),  (2)(i)-(vii),  (3)(i)-(iv), and (4)(iii)-(xv), which the Asserting

respect to the asset-backed  securitization  transactions covered by this report
such  criteria,  after giving effect to the  exclusions  identified  above,  the
"Applicable Servicing Criteria"). This report covers the asset-backed securities

as amended,  where the related  asset-backed  securities  were issued during the
Reporting Period (the "Platform"), as listed in Appendix A.

     The  Asserting  Party  has  (i)  used  the  criteria  set  forth  in 17 CFS
229.1122(d) to assess the compliance by the Asserting  Party with the Applicable
Servicing  Criteria  for the  Reporting  Period  and  (ii)  concluded  that  the

     JPMorgan  Chase  Bank,  National  Association  (the  "Asserting  Party") is
responsible for assessing  compliance as of December 31, 2006 and for the period
from January 1, 2006 through December 31, 2006 (the "Reporting Period") with the
servicing  criteria set forth in Title 17,  Section  229.1122 (d) of the Code of
Federal  Regulations  (the "CFR") as set forth in  Appendix A hereto,  which the
Asserting Party has concluded are applicable to it in connection with its Master
Servicing operations with respect to the transactions listed in Appendix B which
comprise the Master Servicing  platform as defined below, to the extent required
by the related transaction  agreements as to any transaction (such criteria, the
"Applicable  Servicing  Criteria").  For the  purpose  of this  assessment,  the
Asserting  Party has  defined  its Master  Servicing  platform  as all  publicly
offered asset-backed transactions backed by residential mortgages or home equity
loans issued on or after January 1, 2006 where the Asserting Party is the master
servicer (the "Platform").

     The  Asserting  Party  (i)  has  used  the  criteria  set  forth  in 17 CFR
229.1122(d) to assess the compliance by the Asserting  Party with the Applicable
Servicing  Criteria for the  Reporting  Period and (ii) has  concluded  that the
Asserting  Party 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.

     PricewaterhouseCoopers  LLP, an independent  registered  public  accounting
firm,  has issued an  attestation  report for the Platform on our  assessment of
compliance  with the Applicable  Servicing  Criteria as of December 31, 2006 and
for the Reporting Period.

       Assessment Regarding Compliance with Applicable Servicing Criteria

1.   Avelo  Mortgage,   LLC  (the   "Servicer")  is  responsible  for  assessing
     compliance,  as of December  31, 2006 and for the period from  February 24,
     2006 (the  first day of the  distribution  period in which the GS  Mortgage
     Securities Corp. ("GSMSG") first issued securities subject to Regulation AB
     through  December 31, 2006 (the  "Reporting  Period"),  with the  servicing
     criteria set forth in Item 1122(d) of Regulation AB, excluding the criteria
     set  forth  in Item  1122(d)(1)(i),  (d)(1)(iii),  (d)(2)(ii),  (d)(2)(iv),
     (d)(3)(iii), (d)(4)(i), (d)(4)(ii), (d)(4)(iii), (d)(4)(vi), and (d)(4)(xv)
     of Regulation  AB, which the Servicer has  concluded are not  applicable to
     the  activities  it performs,  directly,  with respect to the  asset-backed
     securities transactions covered by this report (such criteria, after giving
     effect  to the  exclusions  identified  above,  the  "Applicable  Servicing
     Criteria").  The transactions in which the Servicer was a party are covered
     by  this  report  included  those  asset-backed   securities   transactions
     conducted  by the  GSMSG  that  were  registered  with the  Securities  and
     Exchange  Commission  pursuant  to the  Securities  Act of 1933  where  the
     related  asset-backed  securities  were  outstanding  during the  Reporting
     Period (the "Platform"), as listed in Appendix A.

2.   The  Servicer  has  engaged  certain  vendors  (the  "Vendors")  to perform
     specific,  limited or scripted  activities for the reporting period and the
     Servicer  elects  to take  responsibility  for  assessing  compliance  with
     certain servicing criteria applicable to such Vendors.

3.   The Servicer has complied,  in all material  respects,  with the applicable
     servicing criteria as of and for the Reporting Period except as follows:

         The Servicer assessed its compliance with the Applicable Servicing
         Criteria for the Reporting Period and has identified a material
         instance of non-compliance with servicing criterion set  forth in
         Item 1122(d)(2)(vii) of Regulation AB with respect to the Platform.
         Specifically, the Servicer did not prepare reconciliations for all
         asset-backed securities related bank accounts within 30 calendar days
         after the bank statement cut-off date, or as such other number of days
         as specified in the transaction agreements and reconciling items were
         not resolved within 90 days of their original identification or such
         other number of days as specified in the transaction agreements.

4.   The Servicer has not identified  and is not aware of any material  instance
     of non-compliance by the Vendors with the applicable servicing criteria for
     the Reporting Period;

5.   The Servicer has not identified any material deficiency in its policies and
     procedures  to monitor the  compliance  by the Vendors with the  applicable
     servicing criteria for the Reporting Period;

6.   PricewaterhouseCoopers  LLP, an independent  registered  public  accounting
     firm, has issued an  attestation  report for the Platform on the assessment
     of   compliance   with   the   Applicable    Servicing   Criteria   as   of
     December 31, 2006 and for the Reporting Period.

1. GreenPoint has identified the following noncompliance with servicing criteria
1122(d)(1)(i),  1122(d)(2)(iv),  and  1122(d)(3)(ii)  applicable to the Platform

certain  securitizations  which  allowed  funds  to  be  commingled  in  various
custodial accounts.

1122(d)(3)(ii) - In certain  situations  where GreenPoint has received  mortgage
insurance  proceeds  prior to the  liquidation  of the related  properties,  the

proper  custodial and escrow accounts and improved the oversight of establishing
such accounts as required by the related agreements.

such mortgage  insurance  proceeds may be remitted at the time of the remittance
of the REO  liquidation  proceeds or modifying its remittance  practice to remit
the mortgage insurance  proceeds during the next regularly  schedule  remittance
where required.

             Report of Independent Registered Public Accounting Firm

To the Board of Directors of JPMorgan Chase Bank, National Association

We have examined  JPMorgan Chase Bank,  National  Association's  (the "Company")
compliance  with  the  servicing  criteria  set  forth  in Item  1122(d)  of the
Securities and Exchange Commission's  Regulation AB as of September 30, 2006 and
for the  period  from  January 1, 2006 to  September  30,  2006 (the  "Reporting
Period") for the  asset-backed  securities  transactions  backed by  residential
mortgages, home equity loans, auto loans, credit card receivables,  dealer floor
plans, retail installment contracts and manufactured housing contracts that were
registered  with  the  Securities  and  Exchange   Commission  pursuant  to  the
Securities Act of 1933, as amended,  where the related  asset-backed  securities
were outstanding  during the Reporting Period (the "Platform")  described in the
accompanying  Management's  Report on Assessment of Compliance  with  Applicable
Servicing  Criteria,  excluding criteria  1122(d)(1)(ii)-(iv),  1122(d)(2)(iii),
1122(d)(2)(vi),  1122(d)(4)(i)-(ii), and 1122(d)(4)(iv)-(xiv), which the Company
has determined are not  applicable to the servicing  activities  performed by it
with respect to the Platform.  Appendix A to management's  assertion  identifies
the individual asset-backed transactions and securities defined by management as
constituting   the  Platform.   Management  is  responsible  for  the  Company's
compliance  with the servicing  criteria.  Our  responsibility  is to express an
opinion on the Company's  compliance  with the servicing  criteria  based on our
examination.

Our examination was conducted in accordance with standards of the Public Company
Accounting Oversight Board (United States) and, accordingly, included examining,
on a test basis,  evidence  about the Company's  compliance  with the applicable
servicing  criteria  and  performing  such  other  procedures  as we  considered
necessary in the  circumstances.  Our examination  included  testing of selected
asset- backed transactions and securities that comprise the Platform, testing of
selected servicing  activities related to the Platform,  and determining whether
the Company  processed those selected  transactions and performed those selected
activities in compliance with the applicable servicing criteria.  Our procedures
were limited to the selected  transactions and servicing activities performed by
the Company  during the period covered by this report.  Our procedures  were not
designed to detect  noncompliance  arising  from  errors that may have  occurred
prior to or  subsequent  to our tests that may have  affected  the  balances  or
amounts  calculated or reported by the Company during the period covered by this
report.  We believe that our  examination  provides a  reasonable  basis for our
opinion. Our examination does not provide a legal determination on the Company's
compliance with the servicing criteria.

Our  examination  disclosed  the  following  material   noncompliance  with  the
servicing  criteria  set  forth in Items  1122(d)(3)(i)  and  1122(d)(3)(ii)  of
Regulation AB  applicable to the Company  during the period from January 1, 2006
to September 30, 2006.  Certain monthly  investor  reports  omitted  information
required  by  the  transaction   agreements   and/or  contained  errors  in  the
information  presented  and certain  monthly  investor  distributions  contained
errors as to the amounts due to certain investors.

In our opinion, except for the material noncompliance described in the preceding
paragraph,   JPMorgan  Chase  Bank,  National   Association  complied  with  the
aforementioned  applicable  servicing  criteria  as of and for the period  ended
September 30, 2006 for the Platform, in all material respects.

We  have  examined   management's   assertion,   included  in  the  accompanying
Management's  Report on  Assessment  of  Compliance  with  Applicable  Servicing
Criteria,  that  JPMorgan  Chase  Bank,  National  Association  (the  "Company")
complied with the servicing criteria set forth in Item 1122(d) of the Securities
and  Exchange  Commission's  Regulation  AB as of December  31, 2006 and for the
period from  October 1, 2006 to December 31, 2006 (the  "Reporting  Period") for
the asset-backed securities  transactions backed by residential mortgages,  home
equity loans, auto loans,  credit cards,  dealer floor plans, retail installment
contracts and  manufactured  housing  contacts,  that were  registered  with the
Securities  and Exchange  Commission  pursuant to the Securities Act of 1933, as

1122(d)(2)(i)-(vi), 1122(d)(3)(i)-(iv) and 1122(d)(4)(i)-(xv), which the Company
has determined are not  applicable to the servicing  activities  performed by it
with  respect  to  the  Platform.  Appendix  A  to  the  management's  assertion
identifies the individual  asset-backed  transactions and securities  defined by
management as  constituting  the Platform.  Management  is  responsible  for the
Company's  compliance  with the servicing  criteria.  Our  responsibility  is to

all material respects.

        Report of Independent Registered Public Accounting Firm

Board of Directors
The Trust & Securities Services department of Deutsche Bank National Trust
        Company and Deutsche Bank Company Americas:

We have examined management's  assertion,  included in the accompanying Appendix
I, that the Trust & Securities  Services  department  of Deutsche  Bank National
Trust  Company  and  Deutsche  Bank Trust  Company  Americas  (collectively  the
"Company") complied with the servicing criteria set forth in Item 1122(d) of the
Securities and Exchange  Commission's  Regulation AB for publicly-issued  (i.e.,
transaction-level  reporting required under the Securities Exchange Act of 1934,
as  amended)  residential  mortgage-backed  securities  and  other  asset-backed
securities  issued on or after January 1, 2006,  for which the Company  provides
trustee,  securities  administration  or paying agent  services,  excluding  any
publicly issued  transactions,  sponsored or issued by any government  sponsored
entity  (the  Platform),  except  for the  servicing  criteria  1122(d)(2)(iii),
1122(d)(4)(iv),       1122(d)(4)(v),      1122(d)(4)(vi),       1122(d)(4)(vii),
1122(d)(4)(viii),       1122(d)(4)(ix),      1122(d)(4)(x),      1122(d)(4)(xi),
1122(d)(4)(xii),  1122(d)(4)(xiii)  and  1122(d)(4)(xiv),  which the Company has
determined  are not applicable to the activities it performs with respect to the
Platform, as of and for the twelve months ended December 31, 2006. Management is
responsible  for the Company's  compliance with those  servicing  criteria.  Our
responsibility  is to express an opinion  on  management's  assertion  about the
Company's compliance based on our examination.

Our  examination  was conducted in  accordance  with the standards of the Public
Company Accounting  Oversight Board (United States) and,  accordingly,  included
examining,  on a test basis,  evidence about the Company's  compliance  with the
servicing  criteria  specified above and performing such other  procedures as we
considered  necessary in the circumstances.  Our examination included testing of
less than all of the individual  asset-backed  transactions  and securities that
comprise  the  Platform,  testing of less than all of the  servicing  activities
related to the Platform,  and  determining  whether the Company  processed those
selected transactions and performed those selected activities in compliance with
the servicing criteria. Furthermore, our procedures were limited to the selected
transactions and servicing activities performed by the Company during the period
covered by this report.  Our procedures  were not designed to determine  whether
errors may have  occurred  either prior to or  subsequent  to our tests that may
have  affected  the  balances or amounts  calculated  or reported by the Company
during the period  covered by this report for the selected  transactions  or any
other transactions.  We believe that our examination provides a reasonable basis
for our opinion.  Our examination does not provide a legal  determination on the
Company's compliance with the servicing criteria.

As described in management's  assertion included in the accompanying Appendix I,
for servicing  criteria  1122(d)(2)(i),  1122(d)(4)(i) and  1122(d)(4)(ii),  the
Company has engaged various vendors to perform the activities  required by these
servicing  criteria.  The  Company  has  determined  that these  vendors are not
considered a "servicer"  as defined in Item  1101(j) of  Regulation  AB, and the
Company has elected to take  responsibility  for assessing  compliance  with the
servicing  criteria  applicable  to each vendor as permitted  by  Interpretation
17.06 of the SEC Division of Corporation  Finance  Manual of Publicly  Available
Telephone   Interpretations    ("Interpretation   17.06").   As   permitted   by
Interpretation  17.06,  the  Company  has  asserted  that  it has  policies  and
procedures in place designed to provide  reasonable  assurance that the vendors'
activities  comply  in  all  material  respects  with  the  servicing   criteria
applicable to each vendor.  The Company is solely  responsible  for  determining
that it meets the SEC requirements to apply Interpretation 17.06 for the vendors
and  related  criteria  as  described  in its  assertion,  and we  performed  no
procedures  with respect to the Company's  eligibility  to apply  Interpretation
17.06.

In our  opinion,  management's  assertion  that the  Company  complied  with the
aforementioned  servicing criteria,  including servicing criteria 1122(d)(2)(i),
1122(d)(4)(i)  and  1122(d)(4)(ii)  for which  compliance is determined based on
Interpretation  17.06 as described  above, as of and for the twelve months ended
December 31, 2006 is fairly stated, in all material respects.

             Report of Independent Registered Public Accounting Firm

To the Stockholder of JPMorgan Chase Bank, National Association:

We  have  examined   management's   assertion,   included  in  the  accompanying
Management's  Report on  Assessment  of  Compliance  with  Applicable  Servicing
Criteria  (the  "Compliance  Statement"),  that  JPMorgan  Chase Bank,  National
Association  (the "Company")  complied with the servicing  criteria set forth in
Item 1122(d) of the  Securities and Exchange  Commission's  Regulation AB, as of
and for the year ended  December  31,  2006 (the  "Reporting  Period"),  for all
publicly  offered  residential  mortgage and home equity  mortgage  asset-backed
securities  issued on or after  January 1, 2006  through  December 31, 2006 (the
"Platform"),  excluding  criteria  set  forth in  Appendix  A to the  Compliance
Statement, which the Company has determined are not applicable to the activities
performed  by it  with  respect  to the  Platform.  Appendix  B to  management's
assertion  identifies the individual  asset-backed  transactions  and securities
defined by management as  constituting  the Platform.  Management is responsible
for the Company's compliance with the servicing criteria.  Our responsibility is
to express an opinion on management's assertion based on our examination.

Our examination was conducted in accordance with standards of the Public Company
Accounting Oversight Board (United States) and, accordingly, included examining,
on a test basis,  evidence  about the Company's  compliance  with the applicable
servicing  criteria  and  performing  such  other  procedures  as we  considered

asset-backed transactions and securities that comprise the Platform,  testing of
selected servicing  activities related to the Platform,  and determining whether
the Company  processed those selected  transactions and performed those selected
activities in compliance with the applicable servicing criteria.  Our procedures
were limited to the selected  transactions and servicing activities performed by
the Company  during the period covered by this report.  Our procedures  were not
designed to detect  noncompliance  arising  from  errors that may have  occurred
prior to or  subsequent  to our tests that may have  affected  the  balances  or

opinion. Our examination does not provide a legal determination on the Company's
compliance with the servicing criteria.

In our  opinion,  management's  assertion  that the  Company  complied  with the
aforementioned  applicable  servicing  criteria  as of and  for the  year  ended
December 31, 2006 for all publicly offered residential  mortgage and home equity
mortgage  asset-backed  securities  issued on or after January 1, 2006 is fairly
stated, in all material respects.

Management's  Report on  Assessment  of  Compliance  with  Applicable  Servicing
Criteria  (the  "Compliance  Statement"),  that  JPMorgan  Chase Bank,  National
Association  (the "Company")  complied with the servicing  criteria set forth in
Item 1122(d) of the  Securities and Exchange  Commission's  Regulation AB, as of
and for the year ended  December  31,  2006 (the  "Reporting  Period"),  for all
publicly  offered  residential  mortgage and home equity  mortgage  asset-backed
securities  issued on or after  January 1, 2006  through  December 31, 2006 (the
"Platform"),  excluding  criteria  set  forth in  Appendix  A to the  Compliance
Statement, which the Company has determined are not applicable to the activities
performed  by it  with  respect  to the  Platform.  Appendix  B to  management's
assertion  identifies the individual  asset-backed  transactions  and securities
defined by management as  constituting  the Platform.  Management is responsible
for the Company's compliance with the servicing criteria.  Our responsibility is
to express an opinion on management's assertion based on our examination.

Our examination was conducted in accordance with standards of the Public Company
Accounting Oversight Board (United States) and, accordingly, included examining,
on a test basis,  evidence  about the Company's  compliance  with the applicable
servicing  criteria  and  performing  such  other  procedures  as we  considered
necessary in the  circumstances.  Our examination  included  testing of selected
asset-backed transactions and securities that comprise the Platform,  testing of
selected servicing  activities related to the Platform,  and determining whether
the Company  processed those selected  transactions and performed those selected
activities in compliance with the applicable servicing criteria.  Our procedures
were limited to the selected  transactions and servicing activities performed by
the Company  during the period covered by this report.  Our procedures  were not
designed to detect  noncompliance  arising  from  errors that may have  occurred
prior to or  subsequent  to our tests that may have  affected  the  balances  or
amounts  calculated or reported by the Company during the period covered by this
report.  We believe that our  examination  provides a  reasonable  basis for our
opinion. Our examination does not provide a legal determination on the Company's
compliance with the servicing criteria.

In our  opinion,  management's  assertion  that the  Company  complied  with the
aforementioned  applicable  servicing  criteria  as of and  for the  year  ended
December 31, 2006 for all publicly offered residential  mortgage and home equity
mortgage  asset-backed  securities  issued on or after January 1, 2006 is fairly
stated, in all material respects.

            Report of Independent Registered Public Accounting Firm


To the Members of Avelo Mortgage, L.L.C.:

We have examined Avelo Mortgage, L.L.C.'s compliance with the servicing criteria
set forth in Item 1122(d) of the Securities and Exchange Commission's Regulation
AB  for  the  asset-backed  securities  transactions  conducted  by GS  Mortgage
Securities  Corp.  (the  "Company") that were registered with the Securities and
Exchange  Commission  pursuant to the  Securities  Act of 1933 where the related
asset-backed  securities  were  outstanding  during the period February 24, 2006
(commencement of loan servicing) to December 31, 2006 (the "Platform") described
in the accompanying Management's Assessment Regarding Compliance with Applicable
Servicing Criteria, as of December 31, 2006 and for the period from February 24,
2006 to December 31, 2006  excluding  criteria  1122(d)(1)(i),  1122(d)(1)(iii),
1122(d)(2)(ii),    1122(d)(2)(iv),     1122(d)(3)(iii),     1122(d)(4)(i)-(iii),
1122(d)(4)(vi),  and  1122(d)(4)(xv),  which the Company has  determined are not
applicable  to the  servicing  activities  performed  by it with  respect to the
Platform.  Appendix  A  to  management's  assertion  identifies  the  individual
asset-backed  transactions and securities  defined by management as constituting
the Platform.  Management is responsible  for the Company's  compliance with the
servicing criteria. Our responsibility is to express an opinion on the Company's
compliance with the servicing criteria based on our examination.

Our examination was conducted in accordance with standards of the Public Company
Accounting Oversight Board (United States) and, accordingly, included examining,
on a test basis,  evidence  about the Company's  compliance  with the applicable
servicing  criteria  and  performing  such  other  procedures  as we  considered
necessary in the  circumstances.  Our examination  included  testing of selected
asset-backed transactions and securities that comprise the Platform,  testing of
selected servicing  activities related to the Platform,  and determining whether
the Company  processed those selected  transactions and performed those selected
activities in compliance with the applicable servicing criteria.  Our procedures
were limited to the selected  transactions and servicing activities performed by
the Company  during the period covered by this report.  Our procedures  were not
designed to detect  noncompliance  arising  from  errors that may have  occurred
prior to or  subsequent  to our tests that may have  affected  the  balances  or
amounts  calculated or reported by the Company during the period covered by this
report.  We believe that out  examination  provides a  reasonable  basis for our
opinion. Our examination does not provide a legal determination on the Company's
compliance with the servicing criteria.

Our  examination  disclosed  the  following  material   noncompliance  with  the
servicing criteria set forth in Item 1122(d)(2)(vii) of Regulation AB applicable
to the Company  during the period from  February 24, 2006  through  December 31,
2006.  Account  reconciliations  for all  asset-backed  securities  related bank
accounts  were not  prepared  within 30 calendar  days after the bank  statement
cutoff  date,  or  such  other  number  of  days  specified  in the  transaction
agreements as required by Item  1122(d)(2)(vii)  and reconciling  items were not
resolved within 90 days of their original  identification,  or such other number
of days specified in the transaction agreements.

In our opinion, except for the material noncompliance described in the preceding
paragraph,  Avelo Mortgage,  L.L.C. complied with the aforementioned  applicable
servicing  criteria  as of and for the period  ended  December  31, 2006 for the
asset-backed  securities  transactions conducted by GS Mortgage Securities Corp.
that were registered with the Securities and Exchange Commission pursuant to the
Securities  Act  of  1933  where  the  related   asset-backed   securities  were
outstanding  during the period  February 24, 2006 to December  31, 2006,  in all
material respects.

Company's compliance based on our examination.

Our  examination  was conducted in  accordance  with the standards of the Public
Company  Accounting  Oversight  Board  (placecountry-regionUnited  States)  and,
accordingly,  included examining,  on a test basis, evidence about the Company's
compliance with the servicing criteria specified above and performing such other
procedures  as we considered  necessary in the  circumstances.  Our  examination
included  testing of less than all of the individual  asset-backed  transactions

servicing  activities  related to the  Platform,  and  determining  whether  the
Company  processed  those  selected  transactions  and performed  those selected

procedures were limited to the selected  transactions  and servicing  activities
performed  by the  Company  during  the  period  covered  by  this  report.  Our

In our  opinion,  management's  assessment  that the Company  complied  with the

             Report of Independent Registered Public Accounting Firm

Board of Directors
GreenPoint Mortgage Funding, Inc.

We have examined  management's  assertion included in the accompanying report of
Certification  Regarding  Compliance with Applicable  Servicing  Criteria,  that
GreenPoint  Mortgage Funding,  Inc. (the "Company")  complied with the servicing
criteria set forth in Item 1122(d) of the Securities  and Exchange  Commission's
Regulation AB for the residential  mortgage loan servicing platform,  except for
the instances of material  noncompliance  described  therein,  as of and for the
year  ended  December  31,  2006,  and  except  for  criteria   1122(d)(1)(iii),
1122(d)(4)(i),  1122(d)(4)(xi),  1122(d)(4)(xii),  and 1122(d)(4)(xv), which the
Company has determined  are not  applicable to the activities  performed by them
with respect to the  servicing  platform  covered by this report.  Management is
responsible for the Company's compliance with the applicable servicing criteria.
Our responsibility is to express an opinion on management's  assertion about the
Company's  compliance  with  the  applicable  servicing  criteria  based  on our
examination.

Our  examination  was  conducted  in  accordance  with   attestation   standards
established  by the  American  Institute  of Certified  Public  Accountants,  as
adopted by the Public Company  Accounting  Oversight  Board (United States) and,
accordingly,  included examining,  on a test basis, evidence about the Company's
compliance  with the applicable  servicing  criteria and  performing  such other
procedures  as we considered  necessary in the  circumstances.  Our  examination
included  testing of less than all of the individual  asset backed  transactions
and  securities  that  comprise  the  platform,  testing of less than all of the
servicing  activities  related to the  Platform,  and  determining  whether  the
Company  processed  those  selected  transactions  and performed  those selected
activities  in compliance  with the  servicing  criteria and as permitted by the
Interpretation  17.06 of the SEC  Division  of  Corporation  Finance  Manual  of
Publicly   Available   Telephone   Interpretations   ("Interpretation   17.06").
Furthermore,  our  procedures  were  limited to the  selected  transactions  and
servicing  activities performed by the Company during the period covered by this
report.  Our procedures  were not designed to determine  whether errors may have
occurred  either prior to or  subsequent to our tests that may have affected the
balances or amounts  calculated  or  reported  by the Company  during the period
covered by this report for the selected  transactions or any other transactions.
We believe that our examination provides a reasonable basis for our opinion. Our
examination does not provide a legal  determination on the Company's  compliance
with the servicing criteria.

As describer in management's assertion, for servicing criteria 1122(d)(2)(i) and
1122(d)(4)(iv),   the  Company  has  engaged  various  vendors  to  perform  the
activities required by these servicing criteria. The Company has determined that
these  vendors are not  considered  a  "servicer"  as defined in Item 1101(j) of
Regulation AB, and the Company has elected to take  responsibility for assessing
compliance with the applicable  servicing criteria  applicable to each vendor as
permitted by  Interpretation  17.06. As permitted by  Interpretation  17.06, the
Company has asserted that it has policies and  procedures  in place  designed to
provide reasonable assurance that the vendors' activities comply in all material
respects  with  servicing  criteria  applicable  to each vendor.  The Company is
solely  responsible for determining  that it meets the SEC requirements to apply
Interpretation  17.06 for the vendors and related  criteria as  described in its
assertion,  and we  performed  no  procedures  with  respect  to  the  Company's
eligibility to apply Interpretation 17.06.

Our examination  disclosed the following  material  noncompliance with servicing
criteria  1122(d)(1)(i),  1122(d)(2)(iv),  and 1122(d)(3)(ii)  applicable to the
Company's  platform  covered by this report  during the year ended  December 31,
2006.  1122(d)(1)(i)  - There were no  policies  and  procedures  instituted  to
monitor the  performance  or other triggers and events of defaults in accordance
with the transaction agreements;  1122(d)(2)(iv) - The related accounts for each
transaction  were not  separately  maintained  as set  forth in the  transaction
agreements;  and, 1122(d)(3)(ii) - Amounts due to investors were not remitted in
accordance with the timeframes set forth in the transaction agreements.

The  information  in the  Certification  Regarding  Compliance  with  Applicable
Servicing  Criteria in Item 2 of Appendix B (i.e.,  remediation  procedures)  is
presented by the Company for information purposes. Such information has not been
subjected to the procedures applied in our examination of management's assertion
as described above, and accordingly, we express no opinion on it.

In our opinion,  except for the material  noncompliance  described in the fourth
paragraph,   the  Company  complied,   in  all  material   respects,   with  the
aforementioned  servicing criteria,  including servicing criteria  1122(d)(2)(i)
and  1122(d)(4)(iv)  for which compliance is determined based on  Interpretation
17.06 as described above, as of and for the year ended December 31, 2006 for the
residential mortgage loan servicing platform.

Annual Compliance Statement

1. A review has been  completed of Avelo  Mortgage,  LLC's  ("Avelo")  servicing
activities and its performance  under the servicing  agreement during the period
from  February 24, 2006 through  December  31, 2006.  This review was  completed
under my supervision.

2. To the best of my knowledge, based on such review, Avelo has fulfilled all of
its  obligations  under  the  agreement  in all  material  respects,  except  as
described in the item below:

For a period  of time in 2006,  bank  accounts  were not  reconciled  in  strict
compliance with Section 1122(d)(2)(vii) of Reg AB which provides as follows:

Reconciliations are prepared on a monthly basis for all asset-backed securities,
related bank accounts,  including  custodial  accounts and related bank clearing
accounts.  These reconciliations are (A) mathematically  accurate;  (B) prepared
within 30 calendar  days after the bank  statement  cutoff  date,  or such other
number  of days  specified  in the  transaction  agreements;  (C)  reviewed  and
approved by someone other than the person who prepared the  reconciliation;  and
(D) contain  explanations for reconciling  items.  These  reconciling  items are
resolved within 90 calendar days of their original identification, or such other
number of days specified in the transaction agreements.

The bank account  reconciliations  were current as of December 31, 2006,  and no
issues were found or arose from the delay in reconciling the bank accounts.

I certify this information to be true and correct to the best of my ability.
