     issuing entity.

     Item 1114(b)(2) of Regulation AB, Significant Enhancement Provider
     Information.

     The consolidated audited financial statements of XL Capital Assurance Inc.
     and Subsidiary and XL Financial Assurance Ltd. as of December 31, 2007
     and 2006 and for the years ended December 31, 2007, 2006 and 2005, which
     appear as Exhibit 99.1 and 99.2, respectively, in Security Capital
     Assurance Ltd's (Commission CIK No. 0001358164), (the "Company"),
     Current Report on Form 8-K of the Company filed with the Securities
     and Exchange Commission by the Company on March 26, 2008 (Commission
     File No. 001-32950) are incorporated by reference herein.

     Item 1115(b) of Regulation AB, Certain Derivative Instruments.

     Goldman Sachs Mitsui Marine Derivative Products, L.P. provides an interest
     rate swap agreement for the issuing entity.  No additional disclosure is
     necessary because the significance percentage for the interest rate swap
     is less than 10%.

     Item 1117 of Regulation AB, Legal Proceedings.

     As of the date of the 424(b)(5) filing, there were no material legal or
     governmental proceedings currently pending or known to be contemplated
     against First Franklin Financial Corporation ("First Franklin Financial").
     To the best of First Franklin Financial's knowledge, there were no
     material legal or governmental proceedings currently pending or known to
     be contemplated against First Franklin Financial, which if ultimately
     decided adversely to First Franklin Financial, would have a material
     adverse effect on the validity of the mortgage loans.

     In the Quarterly Report on Form 10-Q for the period ended September 28,
     2007 filed by Merrill, Lynch & Co., Inc. ("Merrill Lynch") with the
     Securities and Exchange Commission ("SEC") on November 7, 2007, Merrill
     Lynch disclosed that the SEC staff initiated an inquiry into matters
     related to Merrill Lynch's subprime mortgage portfolio. Merrill Lynch
     disclosed that it was cooperating fully with the SEC in this matter.

     In the Annual Report on Form 10-K for the period ended December 31, 2007
     filed by Security Capital Assurance Ltd ("SCA") with the Securities and
     Exchange Commission on March 17, 2008 (the "2007 10-K"), SCA disclosed
     that XL Capital Assurance Inc. ("XLCA") received a grand jury subpoena
     dated November 15, 2006 from the New York Office of the Antitrust
     Division of the U.S. Department of Justice in connection with an
     investigation into the municipal guaranteed investment contract market
     and related products. Thereafter, the Antitrust Division served a
     superseding grand jury subpoena dated November 30, 2006 addressed to
     XL Asset Funding Company I LLC ("XLAF") instead of XLCA. XLAF is a
     subsidiary of XL Capital Ltd ("XL Capital") and is not a subsidiary of
     SCA.

     SCA also disclosed in the 2007 10-K that in December 2007 and January
     2008, three class action lawsuits, Brickman Investments, Inc. v.
     Security Capital Assurance Ltd et al., 2 West, Inc. v. Security Capital
     Assurance Ltd et al., and Clarke v. Security Capital Assurance Ltd et al.,
     were commenced in the United States District Court for the Southern
     District of New York. Two of the lawsuits were filed on behalf of all
     persons who purchased SCA common shares in the secondary public offering
     by XL Insurance (Bermuda) Ltd ("XLI"), a wholly owned subsidiary of XL
     Capital, as selling shareholder, on or about June 6, 2007. The third
     lawsuit was filed on behalf of all persons who purchased or otherwise
     acquired SCA's securities from April 23, 2007 through December 10, 2007,
     including those who purchased shares in the secondary offering. The
     complaints name SCA, its President and Chief Executive Officer, Executive
     Vice President and Chief Financial Officer, and XL Insurance Ltd as
     defendants, and they allege various violations of the Securities Act
     and the Exchange Act by the defendants. Two of the complaints also name
     the lead underwriters of the secondary offering as defendants. The
     complaints include claims that defendants' public statements, including
     the registration statement and prospectus related to the secondary
     offering, contained false and misleading statements and omitted to
     disclose material facts necessary to make the statements contained
     therein not misleading.

     SCA also disclosed in the 2007 10-K that in addition, on March 13, 2008,
     a class action lawsuit, Hinds County, Mississippi v. Wachovia Bank N.A.
     et al., was commenced, also in the United States District Court for the
     Southern District of New York, on behalf of all state, local and
     municipal government entities that purchased municipal derivatives from
     SCA or the other defendants in the period from January 1, 1992 through
     December 31, 2006. The complaint names thirty-six providers and brokers
     of municipal derivatives, including SCA, as defendants. The complaint
     alleges a conspiracy among the defendants to fix, raise, maintain or
     stabilize the price of, and to rig bids and allocate customers and
     market for, municipal derivatives.

     The complaints seek unspecified damages and other relief.

     In the Current Report on Form 8-K filed by Security Capital Assurance
     Ltd ("SCA") with the Securities and Exchange Commission on March 26,
     2008 SCA disclosed that on February 22, 2008 and March 6, 2008, XL
     Capital Assurance Inc. ("XLCA") issued notices terminating seven CDS
     contracts with Merrill Lynch International under which XLCA had agreed
     to make payments to Merrill Lynch International on the occurrence of
     certain credit events pertaining to particular ABS CDOs referenced in
     the agreements.  SCA disclosed that XLCA issued each of the termination
     notices on the basis of Merrill Lynch International's repudiation of
     certain contractual obligations under each of the agreements.  SCA
     disclosed that Merrill Lynch International filed a lawsuit against
     XLCA in New York Federal Court, seeking a declaratory judgment that
     the seven CDS contracts are enforceable against XLCA.  SCA disclosed
     that XLCA believes that Merrill Lynch International's lawsuit lacks
     merit and intends to vigorously defend the terminations.  SCA disclosed
     that the notional amount of the credit default swaps at December 31,
     2007 aggregated $3.1 billion before reinsurance ($0.8 billion after
     reinsurance).  SCA further disclosed that for the year ended December
     31, 2007, XLCA recorded a charge of $180.4 million relating to these
     CDS contracts, of which $56.2 million represents a net unrealized loss
     and is reflected in the accompanying statement of operations in the
     caption entitled "Net realized and unrealized losses on credit
     derivatives," and $124.2 million represents the provision of case basis
     reserves for losses and loss adjustment expenses and is reflected in
     the accompanying statement of operations in the caption entitled, "Net
     losses and loss adjustment expenses."  SCA disclosed that at December
     31, 2007, XLCA recorded a derivative liability and reserves for losses
     and loss adjustment expenses associated with these credit default swap
     contracts of $212.5 million and $509.1 million before reinsurance
     ($56.2 million and $124.2 million after reinsurance), respectively.
