Legal Proceedings Regarding PHH Corporation

PHH Mortgage Corporation, one of the servicers and original loan sellers, is a
subsidiary of PHH Corporation ("PHH").  Pursuant to a Form 10-K filed by PHH on
February 29, 2008 (Commission File No. 001-07797; CIK No. 0000077776), PHH
stated that it is party to various claims and legal proceedings from
time-to-time related to contract disputes and other commercial, employment and
tax matters, and that it is not aware of any pending legal proceedings that it
believes could have, individually or in the aggregate, a material adverse effect
on its business, financial position, results of operations or cash flows.

PHH stated that in March and April 2006, several purported class actions were
filed against PHH, its Chief Executive Officer and its former Chief Financial
Officer in the U.S. District Court for the District of New Jersey.  The
plaintiffs sought to represent an alleged class consisting of all persons (other
than our officers and Directors and their affiliates) who purchased PHH's Common
stock during certain time periods beginning March 15, 2005 in one case and May
12, 2005 in the other cases and ending March 1, 2006.  The plaintiffs alleged,
among other matters, that the defendants violated Section 10(b) of the Exchange
Act and Rule 10b-5 thereunder.  Each of these purported class actions has since
been voluntarily dismissed by the plaintiffs.  Additionally, two derivative
actions were filed in the U.S. District Court for the District of New Jersey
against PHH, its former Chief Financial Officer and each member of its Board of
Directors.  Both of these derivative actions have since been voluntarily
dismissed by the plaintiffs.

PHH also stated that following the announcement of the Merger in March 2007, two
purported class actions were filed against PHH and each member of its Board of
Directors in the Circuit Court for Baltimore County, Maryland (the "Court").
The first of these actions also named GE and Blackstone as defendants.  The
plaintiffs sought to represent an alleged class consisting of all persons (other
than PHH's officers and Directors and their affiliates) holding PHH's Common
stock.  In support of their request for injunctive and other relief, the
plaintiffs alleged, among other matters, that the members of the Board of
Directors breached their fiduciary duties by failing to maximize stockholder
value in approving the Merger Agreement.  On or about April 10, 2007, the claims
against Blackstone were dismissed without prejudice.  On May 11, 2007, the Court
consolidated the two cases into one action.  On July 27, 2007, the plaintiffs
filed a consolidated amended complaint.  This pleading did not name GE or
Blackstone as defendants.  It essentially repeated the allegations previously
made against the members of PHH's Board of Directors and added allegations that
the disclosures made in the preliminary proxy statement filed with the SEC on
June 18, 2007 omitted certain material facts.  On August 7, 2007, the Court
dismissed the consolidated amended complaint on the ground that the plaintiffs
were seeking to assert their claims directly, whereas, as a matter of Maryland
law, claims that directors have breached their fiduciary duties can only be
asserted by a stockholder derivatively.  The plaintiffs have the right to appeal
this decision.



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

The information regarding this Item has been previously disclosed in a 424(b)(5)
filed on October 1, 2007 (Commission File No. 333-139817-18).
