A corrected version follows.) NEW YORK (Standard & Poor's) July 11, 2007--Standard & Poor's Ratings Services said today it placed its credit ratings on 612 classes of residential mortgage-backed securities (RMBS) backed by U.S. subprime collateral on CreditWatch with negative implications (see list below). The affected classes total approximately $7.35 billion in rated securities, which represents 1.3% of the $565.3 billion in U.S. subprime RMBS rated by Standard & Poor's between the fourth quarter of 2005 and the fourth quarter of www.standardandpoors.com/ratingsdirect © Standard & Poor's.

Changes to our rating methodology as well as details of a teleconference to be held today are given below. The CreditWatch actions are being taken at this time because of poor collateral performance, our expectation of increasing losses on the underlying collateral pools, the consequent reduction of credit support, and changes that will be implemented with respect to the methodology for rating new transactions. Many of the classes issued in late 2005 and much of 2006 now have sufficient seasoning to evidence delinquency, default, and loss trend lines that are indicative of weak future credit performance. The levels of loss continue to exceed historical precedents and our initial expectations at the time we rated the deals. We are also conducting a review of CDO ratings where the underlying portfolio contains any of the affected securities subject to these rating actions (see separate media release to be published today). FACTORS DRIVING NEW SURVEILLANCE METHODOLOGY We have been surveilling these transactions on a regular basis and have been monitoring market trends. At this time, we do not foresee the poor performance abating. Loss rates, which are being fueled by shifting patterns in loss behavior and further evidence of lower underwriting standards and misrepresentations in the mortgage market, remain in excess of historical precedents and our initial assumptions. LOSS PATTERNS New data reveals that delinquencies and foreclosures continue to accumulate at an increasing rate for the 2006 vintage. We see poor performance of loans, early payment defaults, and increasing levels of delinquencies and losses. Total aggregate losses on all subprime transactions issued since the fourth quarter of 2005 is 29 basis points, as compared with 7 basis points for similar transactions issued in 2000. Transactions from the 2000 vintage are used as a comparison because they were, up until now, the worst performing vintage of this decade. When recent transactions with the same seasoning are compared on a quarterly basis with similar transactions issued in 2000, we find that both mean losses and standard deviations are running in excess of the 2000 book for the fourth quarter of 2005 through the fourth quarter of 2006. Seriously delinquent loans (90-days-plus, foreclosure, and real estate owned {REO}), on average, also exceed the 2000 book of business for each quarterly comparison except for the fourth quarter of 2005.

See Terms of Use/Disclaimer on the last page. 2 590247 | 300033677 S&PCORRECT: 612 U.S. Subprime RMBS Classes Put On Watch Neg; Methodology Revisions Announced On a macroeconomic level, we expect that the U.S. housing market, especially the subprime sector, will continue to decline before it improves, and home prices will continue to come under stress. Weakness in the property markets continues to exacerbate losses, with little prospect for improvement in the near term. Furthermore, we expect losses will continue to increase, as borrowers experience rising loan payments due to the resetting terms of their adjustable-rate loans and principal amortization that occurs after the interest-only period ends for both adjustable-rate and fixed-rate loans. Although property values have decreased slightly, additional declines are expected. David Wyss, Standard & Poor's chief economist, projects that property values will decline 8% on average between 2006 and 2008, and will bottom out in the first quarter of 2008. While our LEVELS model assumes property value declines of 22% for the 'BBB' and lower rating category stress environments (with higher property value declines for higher rating category stress environments), the continued decline in prices will apply additional stress to these transactions by increasing losses on the sale of foreclosed properties, as well as removing or reducing the borrowers' ability to refinance or sell their homes to meet debt obligations. As lenders have tightened underwriting guidelines, fewer refinance options may be available to these borrowers, especially if their loan-to-value (LTV) and combined LTV (CLTV) ratios have risen in the wake of declining home prices. DATA QUALITY The Mortgage Asset Research Institute (MARI) reports that alleged misrepresentations on credit reports were up significantly as a percentage of total submissions received in 2006. MARI, which was recently commissioned by the Mortgage Bankers Assoc. (MBA) to conduct a mortgage fraud study, reported that the current findings of fraud were in excess of previous industry highs. Data quality concerning some of the borrower and loan characteristics provided during the rating process has also come under question. Therefore, key risk variables that have historically influenced default patterns, such as FICO, LTV, and ownership status, are proving less predictive. It is expected that the ongoing weakness in both national and regional property markets will exacerbate losses with little prospect for improvement in the near term. Also, many of these transactions will likely encounter additional credit stress from upcoming interest rate and payment resets. Data quality is fundamental to our rating analysis. The loan performance associated with the data to date has been anomalous in a way that calls into question the accuracy of some of the initial data provided to us regarding the loan and borrower characteristics. A discriminate analysis was performed to identify the characteristics associated with the group of transactions performing within initial expectations and those performing below initial expectations. The following characteristics associated with each group were www.standardandpoors.com/ratingsdirect © Standard & Poor's. All rights reserved.

Our results show no statistically significant differentiation between the two groups of transactions on any of the above characteristics. Reports of alleged underwriting fraud tend to grow over time, as suspected fraud incidents are detected upon investigation following a loan default. PAYMENT ADJUSTMENTS Adjustable-rate and interest-only loans subject to contractual increases in their monthly payments will continue to put pressure on borrowers' ability to meet monthly payments in the future. The transactions with classes identified for CreditWatch placement contain, on average, 75%-80% of the types of loans that are subject to some type of payment adjustment over the next 18 months. When reviewing the transactions initially, we assumed that borrowers would experience additional stresses when subject to payment adjustments. All loans containing some type of payment increase were assumed to default 20% more often than similar borrowers with fixed-rate loans and FICO scores of less than 660 (including subprime borrowers). Our analysis intended to anticipate the burden and resulting payment shock that a borrower would face assuming rising interest rates. The following table provides the aggregate percentage of 2/1 arms for U.S. subprime transactions by quarter for the period under review. Since there tends to be a lag between origination and securitization, many of the 2/1 hybrid ARM loans will reset approximately seven quarters after the transaction closes. 2/1 ARM Reset Information By Quarter Sold during Orig. subprime % of balance ($) 2/1 ARM (all loans) 2005-Q4 138,888,212,337 64 2006-Q1 108,014,850,161 70 2006-Q2 121,149,551,887 70 2006-Q3 98,332,355,370 62 2006-Q4 98,965,073,697 60 Reset quarter 2007-Q3 2007-Q4 2008-Q1 2008-Q2 2008-Q3 Given all of these current factors, we are refining our surveillance approach for subprime RMBS transactions issued from the fourth quarter of 2005 through the fourth quarter of 2006. Going forward, the ratings methodology for new transactions will also incorporate these factors. SURVEILLANCE METHODOLOGY CHANGES As performance continues to deteriorate, we have increased the severity of the surveillance assumptions we use to evaluate the ongoing creditworthiness for Standard & Poor’s RatingsDirect | July 11, 2007 © Standard & Poor's. All rights reserved. No reprint or dissemination without Standard & Poor's permission. See Terms of Use/Disclaimer on the last page. 4 590247 | 300033677 S&PCORRECT: 612 U.S. Subprime RMBS Classes Put On Watch Neg; Methodology Revisions Announced this group of transactions. The level of severity was increased to 40% from 33% to reflect the average severity that subprime servicers are currently experiencing, which was determined through data collected in our SEAM (Servicer Evaluation Analytical Methodology) database. We will continue to apply this revised severity assumption to delinquencies as they move through the pipeline. Specifically, for subprime collateral, we assume that the REO loans are liquidated evenly within six months. During the same six-month period, 25% of foreclosures and 10% of loans that are 90-plus-days delinquent would be evenly liquidated. During months seven through 12, the remaining 75% of foreclosures and 30% of the loans that are 90-plus-days delinquent will be evenly liquidated. In order to account for the movement of the remaining 90-plus-days delinquent and future delinquent loans through the delinquency pipeline, we assume that our projection of the losses used in month 12 continues and amortizes down in months 13 through 36, which allows for loans presently 60or 30-days delinquent, or current, to enter into the delinquency pipeline in the future. Beginning in the next few days, we expect that the majority of the ratings on the classes that have been placed on CreditWatch negative will be downgraded. We will lower our rating: -- To 'CCC' on any class that does not pass our stress test scenario (a class is expected to experience a principal write-down or, with respect to the senior classes, a principal shortfall) within 12 months, regardless of its current rating; -- To 'B' on any class that does not pass our stress test scenario within 13 to 24 months; -- To 'BB' on any class that does not pass our stress test scenario within 25 to 30 months; and -- To 'BBB' on any class that does not pass our stress test scenario within 31 to 36 months. In addition, we have modified our approach to reviewing the ratings on senior classes in a transaction in which subordinate classes have been downgraded. Historically, our practice has been to maintain a rating on any class that has passed our stress assumptions and has had at least the same level of outstanding credit enhancement as it had at issuance. Going forward, there will be a higher degree of correlation between the rating actions on classes located sequentially in the capital structure. A class will have to demonstrate a higher level of relative protection to maintain its rating when the class immediately subordinate to it is being downgraded. Transactions issued in 2007 have not had adequate seasoning to establish a payment history that would make the outcomes of the delinquency and loss tests detailed above capable of meaningful measurement under our new methodology. However, the same asset risks that are apparent in the transactions issued in 2006 may also be present in the 2007 transactions, as well as in transactions currently being packaged for sale and securitization. Hence, to ensure a consistent application of surveillance methodology we will continue to monitor www.standardandpoors.com/ratingsdirect © Standard & Poor's. All rights reserved.

We will also review these transactions under the revised surveillance methodology, as well as the revised methodology employed for issuing new ratings and may take rating actions, as deemed appropriate, throughout the remainder of 2007. We will also continue our review of second mortgages, including "piggyback seconds," "silent seconds," and closed-end second liens, and expect to publish the results in the near future. We are considering a number of changes to our initial rating methodology, as further described below, so as to better mitigate these concerns going forward. REVISED RATING METHODOLOGY FOR NEW ISSUES For transactions that close on or after July 10, 2007, we will incorporate several changes to our ratings methodology that will result in greater levels of credit protection for rated transactions. Our cash flow methodology assumptions will include a simultaneous combination of faster voluntary and involuntary (default) prepayments that will result in less credit to excess spread. Furthermore, our default expectation for 2/28 hybrid ARM loans will increase by approximately 21%. We are in the process of updating our LEVELS and SPIRE models. A separate article will be released in the next few days describing the revisions to our ratings methodology, and will provide the estimated timing for release of the updated models. UNDERWRITING REVIEW Given the level of loosened underwriting at the time of loan origination, misrepresentation, and speculative borrower behavior reported for the 2006 vintage, we will be increasing our review of the capabilities of lenders to minimize the potential and incidence of misrepresentation in their loan production. A lender's fraud-detection capabilities will be a key area of focus for us. The review will consist of a detailed examination of: (a) the overall capabilities and experience of the executive and operational management team; (b) the production channels and broker approval process; (c) underwriting guidelines and the credit process; (d) quality control and internal audits; (e) the use of third-party due diligence firms, if applicable; and (f) secondary marketing. A new addition to this review process will be a fraud-management questionnaire focusing on an originator's tools, processes, and systems for control with respect to mitigating the potential for misrepresentation.
