1.Beginning on page S-15 of the prospectus supplement under the heading “Risk Factors,” the following disclosure is added:

Financial difficulties of and

developments regarding the

originators and servicers Recently, many originators and servicers of mortgage loans have experienced serious financial difficulties and, in some cases, have entered bankruptcy proceedings. These difficulties have resulted in part from declining markets for their mortgage loans and claims for repurchases by them of mortgage loans previously sold under provisions that require repurchase in the event of early payment defaults or for material breaches of representations and warranties made on mortgage loans originated by them, such as fraud claims. These difficulties have been compounded by a general decline in the willingness by banks and other financial institutions to extend credit to originators and servicers and the resulting disappearance of available credit and liquidity lines to such originators and servicers. Higher delinquencies and defaults may also be contributing to these difficulties by reducing the value of mortgage loan portfolios, requiring originators to take mark to market or sale-related losses. An environment inclusive of declining real estate values may decrease the number of borrowers seeking or able to refinance their mortgage loans, resulting in a decrease in overall originations. In addition, the costs of servicing and advancing on increasingly delinquent mortgage loan portfolios may be rising without a corresponding increase in servicing compensation. These factors, among others, may have the overall effect of increasing costs and expenses of originators and servicers while at the same time decreasing servicing cash flow and loan origination revenues. Financial and operational difficulties may have a negative effect on the ability of the servicers to pursue collection on mortgage loans that are experiencing increased delinquencies and defaults and to maximize recoveries on sale of underlying properties following foreclosure. In some cases, servicers may become overwhelmed by the number of defaulted loans in their servicing portfolios and may be unable or unwilling to pursue collections or other remedies, or commence foreclosure proceedings on defaulted mortgage loans.

The servicers are generally required to make advances in respect of delinquent payments on mortgage loans. There can be no assurance as to the current or continuing financial condition of the servicers or their ability to access markets for financing such advances. If a servicer is experiencing financial difficulties, it may not be able to perform these advancing obligations. Even if the servicers are able to advance amounts in respect of delinquent mortgage loans, their obligations to make such advances may be limited to the extent that they do not expect to recover such advances due to the deteriorating credit of the delinquent mortgage loans.

As described in the prospectus supplement, the originators are generally required to repurchase or substitute for mortgage loans for certain breaches of representations and warranties made by them with respect to the related mortgage loans. The inability to repurchase or substitute for such defective loans or for any early payment defaults would likely cause the mortgage loans to experience higher rates of delinquencies, defaults and losses.

S-2

The yield on your securities may be adversely affected if such events impact the originators or the servicers of mortgage loans in the trust fund. On August 6, 2007, American Home Mortgage Corp., which originated approximately 11% of the mortgage loans, and certain other affiliates each filed voluntary petitions for relief under Chapter 11 of title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware.

In addition, approximately 2%, 7% and 8% of the mortgage loans were originated by GreenPoint Mortgage Funding, Inc., National City Mortgage Co. and Paul Financial, LLC, respectively.

Each of these entities has either become insolvent or otherwise announced its decision to no longer originate mortgage loans. The inability or limited ability of such companies to honor repurchase or substitution obligations in the event of a material breach of representations or warranties made by it with respect to the mortgage loans may adversely affect the value and performance of the certificates. There can be no assurance as to the current or continuing financial condition of the other originators.

See “Risk Factors—Originators and servicers may be subject to litigation, governmental proceedings or adverse economic conditions” in the prospectus.

If the receipt of liquidation

proceeds is delayed or if the

liquidation proceeds are

less than the mortgage

loan balance, you could

suffer a loss on your

certificates Substantial delays could be encountered in connection with the liquidation of delinquent mortgage loans. Further, liquidation expenses such as legal fees, real estate taxes and maintenance and preservation expenses may reduce the portion of liquidation proceeds payable to you. If a mortgaged property fails to provide adequate security for the related mortgage loan, you will incur a loss on your investment if the credit enhancement is insufficient to cover that deficiency.

See also “Risk Factors—Legal and other factors could reduce the amount and delay the timing of recoveries on defaulted loans” in the prospectus.

S-3

2. The risk factor on page S-22 entitled “It may be difficult to resell the offered certificates,” is hereby deleted in its entirety and replaced with the following:

It may be difficult to resell the

offered certificates Due to recent developments in the residential mortgage market in the United States and credit markets generally, there is currently a very limited secondary market for the offered certificates. In particular, the offered certificates are likely to have declined in value since the closing date and may continue to do so in the future. If a secondary market does develop, it might not continue or it might not be sufficiently liquid to allow you to resell any of your certificates. Consequently, you may not be able to sell your certificates readily or at prices that will enable you to realize your desired yield. The market values of the offered certificates are likely to fluctuate. Any of these fluctuations may be significant and could result in significant losses to you.

The secondary market for mortgage-backed securities has experienced periods of illiquidity and may do so in the future. Illiquidity can have a severely adverse effect on the prices of securities that are especially sensitive to prepayment, credit, or interest rate risk.

See also “Risk Factors—You may have difficulty selling your securities or obtaining your desired price” in the prospectus.

3.The statistical information presented in the prospectus supplement regarding the mortgage loans was generally accurate as of the cut-off date (or other date specified, if applicable), but this information has changed, and may have changed materially.  Statistical information regarding the mortgage loans as of April 1, 2008 is presented in the tables below. The information with respect to Debt-to-Income Ratios, Original Combined Loan-to-Value Ratios and Credit Scores (in the aggregate and by loan group) is based upon the original data concerning the borrowers and the values of the mortgaged properties available as of the applicable cut-off date. Investors should consider that as of the date of this supplement, a borrower’s financial condition may be worse than the underlying data indicates, such that the debt-to-income ratios may currently be significantly higher and credit scores may currently be significantly lower than they were as of the cut-off date. Similarly, because housing values have declined in many areas of the country, and the decline has been substantial in some cases, the current loan-to value ratios and combined loan-to-value ratios of the mortgage loans in the trust fund are likely to be worse than shown in the tables below.

S-4

Aggregate Mortgage Loan Statistics

The following statistical information, unless otherwise specified, is based upon the aggregate principal balance of the mortgage loans as of April 1, 2008.

The mortgage loans had the approximate characteristics shown in the following tables. The sum in any column in the following tables may not equal the total indicated due to rounding.

4.On page S-34 of the prospectus supplement, the paragraphs under the heading “Static Pool Information” are deleted in their entirety and replaced with the following:

Certain static pool information may be found at http://www.rbsgcregab.com/ in a PDF file entitled “HarborView 2007-7 Static Pool Historical Deal Information.” Access to this internet address is unrestricted and free of charge.

Various factors may affect the prepayment, delinquency and loss performance of the mortgage loans over time. The various mortgage loan groups for which performance information is shown at the above internet address had initial characteristics that differed from the current characteristics, and may have differed in ways that were material to the performance of those mortgage groups. These differing characteristics include, among others, product type, credit quality, geographic concentration, originator concentration, servicer concentration, average principal balance, weighted average interest rate, weighted average loan-to-value ratio, weighted average term to maturity, and the presence or absence of prepayment penalties. In particular, prospective investors should note that certain of the mortgage groups for which performance information is shown consist in whole or in part of loans that have negative amortization features, while other mortgage groups do not include negative amortization loans. In addition to the prepayment, delinquency and loss performance of similar mortgage loan groups, the static pool information shown at the above internet address includes the performance information of the mortgage loans included in the trust fund. Nonetheless, we do not make any representation, and you should not assume, that the performance information shown at the above internet address is in any way fully indicative of the future performance of the mortgage loans in the trust fund.
