                      EXPLANATORY NOTE

This Amendment No. 1 to the Annual Report on Form 10-K filed with the Securities
and Exchange Commission on April 2, 2007 (Accession No. 0001056404-07-001594)
by Bear Stearns Asset Backed Securities I Trust 2006-4 (the "Initial 10-K"),
for the fiscal year ended December 31, 2006, is being filed for the sole purpose
of restating the assessment of American Security Insurance Company, Standard
Guaranty Insurance Company and TrackSure Insurance Agency, Inc. (the "Asserting
Party") for the reporting period of January 1, 2006 through December 31, 2006.
The restated assessment, provided to the registrant in February 2008, identifies
a material instance of noncompliance with the servicing criteria set forth in
Item 1122(d)(4)(xii) under Regulation AB. Specifically, the Asserting Party did
not have, during the applicable reporting period, sufficient policies and
procedures to capture the information with respect to the Platform Transactions
necessary to determine compliance with Item 1122(d)(4)(xii). In response to a
Securities and Exchange Commission comment, as of January 1, 2008, the Asserting
Party has implemented practices and procedures to capture the information
necessary to assess compliance with Item 1122(d)(4)(xii).

  Item 1117 of Regulation AB, Legal Proceedings.

            Purported Securities Class Action Litigation

On February 14, 2007, New Century Financial Corporation ("NCFC") was served with
the complaint for a purported securities class action (the "Original Complaint")
that was filed on February 12, 2007 in the United States District Court for the
Central District of California against the registrant and certain of its
officers and directors. The complaint alleges that NCFC and the other named
defendants violated federal securities laws by issuing false and misleading
statements and failing to disclose material facts about NCFC, which resulted in
artificially inflated market prices of NCFC's common stock, and that the
plaintiff and the purported class members purchased NCFC's stock at these
artificially inflated market prices between April 7, 2006 and February 7, 2007.
The complaint seeks money damages in favor of its purported class of purchasers
of NCFC's securities, the costs and expenses of the action and other relief that
may be granted by the court.

NCFC has also learned that nine additional purported class
actions were filed in the United States District Court for the Central District
of California between February 8, 2007 and February 20, 2007. These complaints,
with which NCFC has not yet been served and which name the registrant and
certain of its officers and directors as defendants, present in large degree the
same legal and factual issues as the Original Complaint and allege various class
periods, the longest of which is from April 7, 2006 to February 7, 2007. NCFC
anticipates that similar actions may be filed in the future and does not
undertake any obligation to update this disclosure for any similar or related
claims that may be made in this regard. NCFC intends to review the allegations
in these complaints and respond appropriately.

Other Investigations

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

On March 12, 2007, NCFC received a letter from the staff of the Pacific Regional
Office of the Securities Exchange Commission stating that the staff was
conducting a preliminary investigation involving NCFC and requesting production
of certain documents. The staff of the SEC had also previously requested a
meeting with NCFC to discuss the events leading up to NCFC's previous
announcement of the need to restate certain of its historical financial
statements. NCFC intends to cooperate with the requests of the SEC.

NCFC has been engaged in recent ongoing discussions with its state regulators
regarding the NCFC's funding constraints and the impact on consumers who are in
various stages of the loan origination process with NCFC. NCFC has advised these
regulators that it has ceased accepting loan applications. In addition, NCFC has
advised these regulators that at this time, NCFC 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 NCFC. NCFC has been and is
continuing to work cooperatively with these regulators to mitigate the impact
on the affected consumers, including transferring pending loans and loan
applications to other mortgage lenders. NCFC has also been providing daily
reports to its various regulators regarding the status of loans in process in
their states, as well as responding to ad hoc information requests.

On March 13, 2007, NCFC and certain of its subsidiaries received cease and
desist orders from regulators in the States of Massachusetts, New Hampshire,
New Jersey and New York. The cease and desist orders contain allegations that
certain of NCFC'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.

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. 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.
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.

The cease and desist orders generally become permanent if not promptly appealed
by the applicable subsidiaries. NCFC is reviewing these orders and accordingly
has not yet determined whether it will appeal all or any portion of any of the
orders. Subject to its funding limitations, NCFC intends to comply with the
orders pending any such appeal.

NCFC anticipates that orders similar to those described above will be received
by NCFC or its subsidiaries from additional states in the future and does not
undertake, and expressly disclaims, any obligation to update this disclosure for
any such additional orders or for any developments with respect to the cease and
desist orders described above.

NCFC intends to continue to cooperate with its regulators in order to mitigate
the impact on consumers resulting from NCFC's funding constraints.

Additional State Regulatory Actions

On March 13, 2007, NCFC received cease and desist orders from the States of
Massachusetts, New Hampshire, New Jersey and New York (the "March 13 Orders").
On March 14 and 15, 2007, NCFC received additional cease and desist orders from
the States of Connecticut, Maryland, Rhode Island and Tennessee (collectively,
the "March 14-15 Orders"). Consistent with the March 13 Orders, the March 14-15
Orders contain allegations that certain of NCFC's subsidiaries have engaged in
violations of applicable state law, including, among others, failure to fund
mortgage loans after closing. Additionally, on March 14, 2007, New Century
Mortgage Corporation and Home123 Corporation, an indirect wholly owned
subsidiary of NCFC ("Home123"), 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").

Consistent with the March 13 Orders, the March 14-15 Orders and the
Consent Agreement seek to restrain NCFC'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 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 NCFC's subsidiaries or assess
administrative penalties.

The March 14-15 Orders generally become permanent if not promptly appealed by
the applicable subsidiaries. NCFC 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.

On March 14, 2007, in connection with a civil action filed against NCFC, New
Century Mortgage Corporation and Home123 Corporation (collectively, the
"Defendants") on March 14, 2007 in an Ohio state court (the "Complaint") by
the Attorney General of Ohio and the Ohio Division of Commerce, Division of
Financial Institutions, that Ohio state court issued a temporary restraining
order, which was subsequently modified by the court on March 16, 2007, against
the Defendants (as modified, the "TRO"). The Complaint and the TRO contain
allegations that the Defendants have engaged in violations of applicable state
law, including, among others, failure to fund mortgage loans after closing. The
TRO restrains the Defendants from taking certain actions, including, among
others, (i) engaging in violations of state law, (ii) soliciting applicants and
taking new applications for mortgage loans in Ohio and (iii) initiating,
prosecuting or enforcing foreclosure actions in Ohio. The TRO also requires the
Defendants 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. The restraints imposed by the TRO could
further harm NCFC's business. NCFC is reviewing the Complaint and the TRO and
accordingly has not yet determined whether it will appeal all or any portion of
the TRO. Subject to its funding limitations, NCFC intends to comply with the TRO
pending any such appeal.

NCFC anticipates that cease and desist orders will continue to be received by
NCFC and its subsidiaries from additional states in the future and that NCFC
and its subsidiaries may enter into additional consent agreements similar to
the Consent Agreement. NCFC does not undertake, and expressly disclaims, any
obligations to update this disclosure for any such additional cease and desist
orders or consent agreements or for any developments with respect to the March
14-15 Orders, the Consent Agreement or the Complaint and the TRO.

NCFC intends to continue to cooperate with its regulators in order to
mitigate the impact on consumers resulting from NCFC's funding constraints.






  Item 1119 of Regulation AB, Affiliations and Certain Relationships and
             Related Transactions.


            On February 9, 2007, Bear Stearns Residential Mortgage Corporation,
            a wholly owned subsidiary of The Bear Stearns Companies Inc. and an
            affiliate of the Registrant, acquired certain assets used in the
            subprime wholesale mortgage banking division of Performance Credit
            Corporation (formerly known as Encore Credit Corp.) ("PCC"), a
            California corporation that, until February 9, 2007, originated and
            purchased one-to four-family residential mortgage loans offered to
            borrowers with a particular emphasis on "nonconforming" borrowers
            who generally do not satisfy the credit, collateral, documentation
            or other standards required by conventional mortgage lenders and
            loan buyers.


  Item 1122 of Regulation AB, Compliance with Applicable Servicing Criteria.


            The servicing criteria have been completed within the manner stated
            in the governing documents and are attached hereto under Item 15.


            The restated assessment of American Security Insurance Company,
            Standard Guaranty Insurance Company and TrackSure Insurance Agency,
            Inc. (the "Asserting Party") for the reporting period of January 1,
            2006 through December 31, 2006, provided to the registrant in
            February 2008, identifies a material instance of noncompliance with
            the servicing criteria set forth in Item 1122(d)(4)(xii) under
            Regulation AB. Specifically, the Asserting Party did not have,
            during the applicable reporting period, sufficient policies and
            procedures to capture the information with respect to the Platform
            Transactions necessary to determine compliance with Item 1122(d)(4)
            (xii). In response to a Securities and Exchange Commission comment,
            as of January 1, 2008, the Asserting Party has implemented practices
            and procedures to capture the information necessary to assess
            compliance with Item 1122(d)(4)(xii).


            The 1122 statements for Wells Fargo Bank, National Association
            (Corporate Trust Services) has disclosed material noncompliance with
            criterion 1122(d)(3)(i), as applicable to the Company during the
            twelve months ended December 31, 2006.  Certain monthly investor or
            remittance reports included errors in the calculation and/or the
            reporting of delinquencies for the pool assets.


            The 1122 statements for Wells Fargo Bank, N.A. (servicer) has
            disclosed the following instances of material noncompliance with
            certain servicing criteria applicable to the Company during the year
            ended December 31, 2006:

            1. 1122(d)(3)(i) - Delinquency Reporting - The Company provided
               incomplete data to some third parties who use such data to
               calculate delinquency ratios and determine the status of loans
               with respect to bankruptcy, foreclosure or real estate owned.
               Instead of the actual due date being provided for use in
               calculating delinquencies, the date of the first payment due to
               the security was provided.

            2. 1122(d)(4)(vii) - Notification of Intent to Foreclose - The
               Company, as required by certain servicing agreements, did not
               provide investors with prior notification of intent to foreclose.



  Item 1123 of Regulation AB, Servicer Compliance Statement.


            The servicer compliance statements have been completed within the
            manner stated in the governing documents and are attached hereto
            under Item 15.
