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.

The information regarding this Item has been previously filed in a 424(b)(5)
filing dated August 31, 2007.

In addition, 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 Product, 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 Product, 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.

HomEq Servicing Corporation has disclosed the following material instance of
non-compliance for the year ended December 31, 2007: the foreclosure was not
initiated in accordance with the timeframes established by its servicing
agreements and the servicing criteria set forth in 1122(d)(4)(vii).

Option One Mortgage Corporation has identified the following noncompliance with
servicing criteria 1122(d)(4)(vi) applicable to the platform as of December 31,
2007 and for the Reporting Period. 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 irst 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.
