No entity or group of affiliated entities provides any external credit
enhancement or other support for the certificates within this transaction as
described under Item 1114 (a) of Regulation AB.



Item 1115(b) of Regulation AB, Certain Derivatives Instruments (Financial
Information).

Bear Stearns Financial Products Inc. provides an Interest Rate Swap derivative
instrument for the trust as disclosed in the 424 Prospectus.  No additional
disclosure is necessary because the significance percentage for the Interest
Rate corridor is less than 10%.

On March 16, 2008, JPMorgan Chase & Co. agreed to guarantee the obligations of
Bear Stearns Financial Products Inc. under the Interest Rate Swap pursuant to
the terms of the Guaranty Agreement described below in Item 1119.  Additional
disclosure with respect to JPMorgan Chase & Co. can be found below in Item 1119.
The significance percentage represented by the guarantee of the Interest Rate
Swap is less than 10%.  Except with respect to the addition of this guarantee,
the terms and conditions of the Interest Rate Swap remain unchanged.



Item 1117 of Regulation AB, Legal Proceedings.

The following updates disclosure which originally provided in connection with
the Form 424B5 filed on 2/16/2007 by the trust, SEC Accession
No. 0000911420-07-000137.

The sponsor has received a civil investigative demand (CID), from the Federal
Trade Commission (FTC), seeking documents and data relating to the sponsor's
business and servicing practices. The CID was issued pursuant to a
December 8, 2005 resolution of the FTC authorizing non-public investigations
of various unnamed subprime lenders, loan servicers and loan brokers to
determine whether there have been violations of certain consumer protections
laws. The sponsor is cooperating with the FTC's inquiry.

On March 10, 2008, EMC received notice from the Staff of the FTC that the Staff
believed EMC and its parent, The Bear Stearns Companies, Inc. had violated a
number of Federal consumer protection statutes in connection with its servicing
activities.  With the notice, the Staff delivered a draft complaint and draft
consent order seeking certain injunctive relief regarding business practices and
unspecified monetary redress. The Staff also indicated that it had been
authorized to offer an opportunity to resolve the matter though consent
negotiations before it seeks approval from the FTC to proceed with the filing
of a complaint. EMC expects to engage in such discussions with the Staff.




RODRIGUEZ v. EMC Mortgage Corporation and The Bear Stearns Companies

This purported class action is pending in U. S. District Court for the District
of Connecticut. The case was filed in December 2007. It seeks certification
of a class made up of African-American and Hispanic borrowers who had a
non-prime loan serviced by EMC and who were subjected to allegedly improper
servicing practices, including imposition of unwarranted fees, pyramiding of
late fees, unjustified forced-placing of insurance, failure to properly apply
payments, improper reporting of derogatory credit information, and failure to
properly administer escrow accounts. EMC and Bear Stearns have filed motions
to dismiss and to strike.



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 February 16, 2007.

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 the 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 the Bear Stearns Financial Products
Inc.'s obligations under the Interest Rate Swap. 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 remain unchanged.

business and commercial banking, financial transaction processing, asset
management, and private equity. A component of the Dow Jones Industrial
