Item 1117 of Regulation AB, Legal Proceedings.

Ocwen Loan Servicing, LLC
On February 9, 2006, a trial court in Galveston, Texas entered judgment in the
amount of $1.8 million in compensatory and statutory damages and attorneys' fees
against Ocwen Loan Servicing, LLC ("Ocwen") in favor of a plaintiff borrower
whose mortgage loan was serviced by Ocwen. The plaintiff brought the claims
under the Texas Deceptive Trade Practices Act and other state statutes and
common law generally alleging that Ocwen engaged in improper loan servicing
practices. Ocwen appealed the decision and the litigation concluded with a final
settlement on January 16, 2008.

WMC Mortgage Corp.
On or about February 6, 2008, Franklin Credit Management Corporation
("Franklin") filed an action against WMC Mortgage, LLC ("WMC") in Supreme Court
of New York, New York County, seeking to have WMC repurchase approximately 440
loans that WMC had sold to Franklin in September and November 2006. Franklin
alleges that WMC breached certain representations and warranties in the loan
sale agreements and claims that it has incurred damages in excess of $35
million. Franklin also seeks attorney fees. WMC's initial response to the
complaint is due on April 4, 2008.

On or about December 7, 2007, PMI Mortgage Insurance Co. ("PMI") and PMI
Guaranty Co. ("PGC"), affiliated insurance companies, initiated an action
against WMC Mortgage Corp. ("WMCMC") and GE Money Bank in the Superior Court of
California, County of Los Angeles, seeking to have WMCMC specifically perform
and repurchase 120 mortgage loans.  The loans at issue are part of a pool of 5,
000 loans that had been originated by WMCMC, and through a series of subsequent
transactions, transferred to a trust (the "Trust"), which issued securities
secured by the loans.  PMI and PGC separately contracted with the Trust to
insure $29.6 million of payments of the mortgage loans (PMI) or principal and
interest payments (PGC) on one particular class of securities.  The complaint
alleges that WMCMC breached certain representations and warranties in the loan
sale agreements.  PMI and PGC also assert claims for negligent and intentional
misrepresentation.  They seek unspecified damages and punitive damages, but do
not allege making any payments under their policies.  WMCMC has filed a motion
to dismiss the complaint.

On or about May 4, 2007, two former salespersons, Charmaine Van Heyn and
Christine Boskovich, filed a class action complaint against WMCM and WMC-GEMB
Mortgage Corp. in Superior Court of the State of California, Los Angeles County
on behalf of all California business development representatives ("BDRs") and
business development associates ("BDAs").   The complaint alleges that WMCMC
violated various provisions of the Fair Labor Standards Act, the California
Labor Code, and the California Business and Professions Code. In substance, the
claims are that: (1) all the putative class members should have been paid
overtime; (2) BDRs were improperly required to pay other employees in violation
of California wage deduction laws; (3) the compensation of some members of the
putative class violated minimum wage laws; (4) the putative class members did
not receive meal and rest breaks; (5) accurate wage statements were not
provided; and (6) not all expenses were reimbursed.  Plaintiffs seek general,
liquidated and punitive damages, and attorney's fees.  WMCMC has denied the
allegations in the complaint; the parties are currently engaged in discovery.

On or about July 11, 2007, the National Association for the Advancement of
Colored People ("NAACP") filed a class action complaint against eleven mortgage
lenders, including WMCMC, in United States District Court in the Central
District of California, alleging that the lenders violated the Fair Housing Act
("FHA"), 42 U.S.C. Section 3601, et seq., the Equal Credit Opportunity Act
("ECOA"), 15 U.S.C. Section 1691, et seq., and the Civil Rights Act ("CRA"), 42
U.S.C. Section 1981, 1982. NAACP has amended the complaint twice and the number
of defendants is now seventeen. In the second amended complaint, filed on March
8, 2008, NAACP bases its claims of discrimination against WMCMC on assertions,
inter alia, that (1) WMCMC unlawfully "steered" African American consumers to
less favorable subprime mortgage loans and (2) WMCMC marketed to minorities
adjustable rate loans with low initial rates without evaluating the ability of
the applicant to pay the subsequent adjusted higher rate. NAACP purports to
bring the action as a class action "on behalf of itself and all others similarly
situated, as well as on behalf of the General Public and Acting in the Public
Interest," and seeks declaratory, equitable and injunctive relief, and
attorneys' fees and costs. Pursuant to a Stipulated Initial Case Management
Order entered by the Court on March 14, 2008, defendants may move to dismiss the
Second Amended Complaint by April 4, 2008, a hearing thereon is scheduled for
June 2, 2008, a schedule/status conference is scheduled for July 7, 2008, and no
discovery is to occur until after the Conference.

On or about January 25, 2008, two alleged "minority borrowers" filed a class
action complaint (Lopez et al. v. GE Money Bank et al.) against GE Money Bank,
and WMCMC and WMC in United States District Court in the Central District of
California asserting that defendants' credit pricing policy had a discriminatory
impact on minority applicants for home mortgage loans, in violation of the Fair
Housing Act ("FHA"), 42 U.S.C. Section 3601, et seq., the Equal Credit
Opportunity Act ("ECOA"), 15 U.S.C. Section 1691, et seq., and the Civil Rights
Act ("CRA"), 42 U.S.C. Section 1981, 1982. Plaintiffs seek disgorgement of "all
disproportionate non-risk charges imposed on minority borrowers," restitution,
actual and punitive damages, declaratory and injunctive relief, including an
order enjoining, inter alia, "any non-risk-related discretionary policy employed
by Defendants," and attorneys' fees and costs. As of March 24, 2008, plaintiffs
had not served the complaint on any of the defendants.
