Item 1117 of Regulation AB, Legal Proceedings.

Perrie Bonner v. H&R Block Mortgage Corporation; Phillips v. H&R Block Mortgage
Corporation, Option One Mortgage Corporation; and, H&R Block, Inc.
(California); and Wojtzcek v. H&R Block Mortgage Corporation (Wisconsin). On
April 29, 2005, H&R Block Mortgage Corporation ("HRBMC") was named as a
defendant and served with a class action complaint filed by Perrie Bonner, as
plaintiff, in the United States District Court for the Northern District of
Indiana, Hammond Division. The complaint alleges that HRBMC accessed the
plaintiff's consumer report without his consent or for any lawful reason, in
violation of the Fair Credit Reporting Act ("FCRA"). This action is one of
several actions filed earlier against other lenders by the same plaintiff and
his attorneys on a similar basis in the same court. The Wojtzcek and Phillips
actions allege similar violations. HRBMC moved before the Multidistrict
Judicial Panel to seek a transfer of the three complaints, which ordered the
transfer of the three actions to the Northern District of Indiana, Judge Rudy
J. Lozano, for coordinated pretrial proceedings. On August 10, 2007, the Court
granted class certification, certifying three classes: (1) in Bonner, all
persons within the Northern District of Indiana to whom HRBMC sent a
solicitation between April 29, 2003 and May 19, 2005 and who did not obtain
credit in response thereto; (2) in Phillips, all persons in Harris County,
Texas to whom HRBMC sent a solicitation during the longest permissible
statutory period; and (3) in Wojtczak, all persons with a Wisconsin address to
whom HRBMC sent a solicitation since November 20, 2004. HRBMC has been ordered
to provide class lists to plaintiffs' counsel by March 7, 2008; plaintiffs'
counsel then has 30 days within which to mail class notices (at plaintiffs'
counsel's expense) or settle the cases individually.

Fees, et al. v. Option One Mortgage Corporation (putative class action filed in
August 2001 in the Circuit Court of Cook County, Illinois, on behalf of
borrowers allegedly charged an illegal title indemnity and/or reconveyance fee
as a condition of releasing their mortgages). The class certification hearing
occurred on January 31, 2006, after which the court certified a nationwide
class. Option One Mortgage Corporation's appeal of the certification was denied
by the appellate court on September 14, 2006. Option One Mortgage Corporation
is waiting for plaintiffs' counsel to specify his classes, which it anticipates
will be severely limited, if not eliminated by, motions to decertify.

Freitag, et al. v. Option One Mortgage Corporation (putative class action filed
July 29, 2004 in Madison County, Illinois). The complaint seeks certification
of a nationwide class and alleges that Option One Mortgage Corporation engages
in the practice of improperly retaining extra per diem interest on residential
mortgage loans by charging per diem interest up to and including the date of
payoff. Settlement in the amount of $25,000 to the named plaintiff received
court approval on January 1, 2005. Plaintiffs' counsel filed an amended
complaint naming new class representatives on June 10, 2005. Option One
Mortgage Corporation filed a notice of removal to federal court and a motion to
compel arbitration. Plaintiffs have filed a motion to remand. Plaintiffs agreed
to stay further proceedings pending a decision of the Illinois Supreme Court in
the Kinkel case regarding the enforceability of arbitration agreements that
contain class action waivers. Kinkel decision issued October 5, 2006; held that
class action waivers were not per se unconscionable. Judge Byron held in favor
of lender in identical case (Hogle v. Wachovia Mortgage Corp.) on April 21,
2006; case currently on appeal. If upheld on appeal, this case will be
dismissed.

In December, 2007, Option One Mortgage Corporation was served with a law suit
by the National Association for the Advancement of Colored People (NAACP),
which lists twelve other defendants, and alleges discrimination and fair
housing violations. The current analysis of Option One Mortgage Corporation's
legal department is that Option One Mortgage Corporation will be removed as a
defendant in this case.

Schueler, et al v. H&R Block Mortgage Corporation and Option One Mortgage
Corporation. On April 9, 2007, HRMBC and Option One Mortgage Corporation were
named as defendants and served with a class action complaint filed by Melissa
Schueler, et al., as plaintiff, in the United States District Court for the
Central District of California, Southern Division. The complaint alleges that
Option One Mortgage Corporation's affiliate, HRBMC, failed to pay overtime
wages to its loan officers in accordance with the Fair Labor Standards Act and
that such alleged failure constitutes an unfair business practice under
California's Business and Professions Code. Option One Mortgage Corporation is
named as a defendant under the theory that it and HRBMC operate as a single
employer. Option One Mortgage Corporation and HRBMC's motion to dismiss was
denied. On January 24, 2008, the Court issued an Order granting in part and
denying in part plaintiff's Motion for Notice pursuant to 29 U.S.C. 216(b). On
February 13, 2008, Notice to Present and Former Employees, Consent to Join and
Stipulated Proposed Order was submitted to the Court for approval.

H&R Block Mortgage received a Civil Investigative Demand from the Federal Trade
Commission on 2/22/2006 regarding voicemail broadcasts. H&R Block Mortgage has
been cooperating with the FTC and producing records in response to the CID.

On September 4, 2007, Option One Mortgage Corporation was served with a class
action lawsuit filed in United States District Court for the Northern District
of Illinois, Eastern Division (Shavers v. Option One Mortgage Corporation).
Option One Mortgage Corporation is the fourth defendant named in similar suits.
The suit alleges discrimination and fair housing violations. Option One
Mortgage Corporation filed its motion to dismiss November 13, 2007 based on
Bell Atl. Corp. v Twombly 127 Supreme Court 55 (2007). The current analysis of
Option One Mortgage Corporation's legal department is that Option One Mortgage
Corporation will be dismissed from this case.

On November 14, 2007, Option One Mortgage Corporation received a Joint
Subpoena/Investigative Demand from the Ohio Attorney General and the Ohio
Department of Commerce. The Demand indicates an investigation into the
possibility of 1) unfair and deceptive acts and practices in connection with
the servicing and foreclosure of loans; 2) non compliance with the Ohio Second
Mortgage Loan Act; and 3) violation of the state anti-trust statute as it
relates to creation and rating of subprime mortgage investment vehicles. Option
One Mortgage Corporation is cooperating with the Attorney General's office
producing records in response to the CID.

On March 29, 2007 Option One Mortgage Corporation received notice of a Civil
Investigative Demand ("CID") issued by the Office of the Attorney General for
the Commonwealth of Massachusetts. The CID states that the Massachusetts
Attorney General is seeking certain information as part of a pending
investigation "regarding methods, acts or practices allegedly in violation of
G. L. C. 93A, Section 2(a), in connection with residential mortgage loans." In
addition, On August 29, 2007, Option One Mortgage Corporation received a
follow-up CID that included requests for new documents as well as expanded
information pertaining to documents previously provided. Option One Mortgage
Corporation has been cooperating with the Attorney General's Office producing
records in response to the CID. On March 4, 2008, Option One Mortgage
Corporation received a letter pursuant to the above named statute that provided
notice of an intent to bring suit against Option One Mortgage Corporation if
the matter could not be resolved.



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

Bear Stearns Financial Products Inc.

On March 16, 2008, JPMorgan Chase & Co. ("JPMorgan Chase") announced that it
had entered into an Agreement and Plan of Merger, dated March 16, 2008 (the
"Agreement and Plan of Merger"), and subsequently amended by Amendment No. 1 to
the Agreement and Plan of Merger, dated as of March 24, 2008 (such amendment,
together with the Agreement and Plan of Merger, the "Merger Agreement"), with
The Bear Stearns Companies Inc., the parent company of Bear Stearns Financial
Products Inc. The Merger Agreement provides that, upon the terms and subject to
the conditions set forth in Merger Agreement, a wholly-owned subsidiary of
JPMorgan Chase will merge with and into The Bear Stearns Companies Inc. with
The Bear Stearns Companies Inc. continuing as the surviving corporation and as
a wholly-owned subsidiary of JPMorgan Chase. The Merger Agreement has been
approved by the Boards of Directors of The Bear Stearns Companies Inc. and
JPMorgan Chase and is subject to customary closing conditions, including
stockholder approval. The Federal Reserve, the Office of the Comptroller of the
Currency and other federal agencies have given all necessary approvals for the
merger. The merger is expected to be completed by the end of the second
calendar year quarter of 2008, however there can be no assurance that the
merger will close as contemplated.

In connection with the Merger Agreement, JPMorgan Chase issued an Amended and
Restated Guaranty Agreement, effective as of March 16, 2008 (the "Guaranty"),
guaranteeing the obligations and liabilities of The Bear Stearns Companies Inc.
and certain of its affiliates, including Bear Stearns Financial Products Inc.'s
obligations under the interest rate swap agreement. A copy of the Guaranty is
filed as Exhibit 99.1 to this Form 10-K. Except with respect to the addition of
this Guaranty, the terms and conditions of the interest rate swap agreement
remain unchanged.

JPMorgan Chase is a financial holding company incorporated under Delaware law,
whose principal office is located in New York, New York. JPMorgan Chase
services include investment banking, financial services for consumers, small
business and commercial banking, financial transaction processing, asset
management, and private equity. A component of the Dow Jones Industrial
Average, JPMorgan Chase serves millions of consumers in the United States and
many of the world's corporate, institutional and government clients under its
JPMorgan and Chase brands.



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

The reports on assessment of compliance with the servicing criteria for
asset-backed securities and the related attestation reports on such assessments
of compliance are attached hereto under Item 15.

Option One Mortgage Corporation has identified the following noncompliance with
servicing criteria 1122(d)(4)(vi) applicable to the platform. For SEC
Regulation AB 1122(d)(4)(vi), loan modifications are required to be completed
in accordance with the transaction agreements and related pool asset documents.
Management notes instances of conflicting language within three PSAs where the
verbiage first indicates to generally modify loans if in the best interest of
the trust, but later qualifies the allowable interest rate reduction.
Non-compliance within this Regulation AB criterion is a result of Management's
incorrect interpretation of the former guidance taking precedence.



Item 1123 of Regulation AB, Servicer Compliance Statement.

The servicer compliance statements are attached hereto under Item 15.
