There are seventeen classes of certificates representing the trust. See “Description of the Certificates” in this free writing prospectus.

The Mortgage Loans

References to percentages of the mortgage loans under this section are calculated based on the aggregate principal balance of the mortgage loans as of the Cut-off Date.

For additional information regarding the Mortgage Loans, see “The Mortgage Pool” in this free writing prospectus.

Removal and Substitution of a Mortgage Loan

The Trustee will acknowledge the sale, transfer and assignment of the trust fund to it by the Depositor and receipt of, subject to further review and the exceptions, the Mortgage Loans. If the Trustee has actual knowledge that any Mortgage Loan is defective on its face due to a breach of the representations and warranties with respect to that Mortgage Loan made in the transaction agreements, the Trustee shall promptly notify the Sponsor of such defect. The Sponsor must then correct or cure any such defect within 90 days from the date of notice from the Trustee of the defect and if the Sponsor fails to correct or cure such defect within such period and such defect materially and adversely affects the interests of the Certificateholders in the related Mortgage Loan, the Sponsor will, in accordance with the terms of the pooling and servicing agreement, within 90 days of the date of notice, repurchase such Mortgage Loan or provide the Trustee with a substitute Mortgage Loan (if within two years of the Closing Date); provided that, if such defect would cause the Mortgage Loan to be other than a “qualified mortgage” as defined in Section 860G(a)(3) of the Internal Revenue Code, any such cure, repurchase or substitution must occur within 90 days from the date such breach was discovered.

The Certificates

Offered Certificates. The Class A Certificates and the Mezzanine Certificates are the only classes of certificates offered by this free writing prospectus and are referred to in this free writing prospectus as the “Offered Certificates”. The Offered Certificates will have the characteristics shown in the table on the cover of this free writing prospectus and as described in this free writing prospectus.

The pass-through rate on each class of Offered Certificates is variable and will be calculated for each Distribution Date as described below and under “Description of the Certificates- Pass-Through Rates” in this free writing prospectus. The pass-through rate on each class of Offered Certificates is a rate per annum based on one-month LIBOR plus an applicable spread, subject to a rate cap, in the case of the Class A-1 Certificates and Class A-2 Certificates, calculated as the weighted average mortgage rate of the Mortgage Loans in the related loan group, less the fee rates payable to the Master Servicer, the Servicer and the Credit Risk Manager (collectively, the “Administration Costs”) and an amount, expressed as a per annum rate, equal to (x) the product of (i) the sum of the net swap payment payable to the swap provider and any swap termination payment payable to the swap provider which is not payable as a result of the occurrence of a swap provider trigger event allocable to the related loan group and (ii) 12, divided by (y) the aggregate principal balance of the Mortgage Loans in the related loan group as of the last day of the immediately preceding Due Period (or as of the Cut-off Date with respect to the first Distribution Date), after giving effect to principal prepayments received during the related Prepayment Period which were distributed on the immediately preceding Distribution Date, in each case, adjusted for the actual number of days which have elapsed in the related interest accrual period and, in the case of the Mezzanine Certificates, calculated as the weighted average of the rate caps of the Class A-1 Certificates and Class A-2 Certificates, weighted in proportion to the results of subtracting from the aggregate principal balance of each loan group the certificate principal balance of the related Class A Certificates. The initial spread relating to the Class A-1 Certificates is [_____]% per annum. The initial spread relating to the Class A-2A Certificates is [_____]% per annum. The initial spread relating to the Class A-2B Certificates is [_____]% per annum. The initial spread relating to the Class A-2C Certificates is [_____]% per annum. The initial spread relating to the Class A-2D Certificates is [_____]% per annum. The initial spread relating to the Class M-1 Certificates is [_____]% per annum. The initial spread relating to the Class M-2 Certificates is [_____]% per annum. The initial spread relating to the Class M-3 Certificates is [_____]% per annum. The initial spread relating to the Class M-4 Certificates is [_____]% per annum. The initial spread relating to the Class M-5 Certificates is [_____]% per annum. The initial spread relating to the Class M-6 Certificates is [_____]% per annum. The initial spread relating to the Class M-7 Certificates is [_____]% per annum. The initial spread relating to the Class M-8 Certificates is [_____]% per annum. The initial spread relating to the Class M-9 Certificates is [_____]% per annum. Each spread is subject to increase as more fully described under “Description of the Certificates-Pass-Through Rates” in this free writing prospectus.

The Offered Certificates will be sold by the Depositor to Deutsche Bank Securities Inc. (the “Underwriter”) on the Closing Date.

The Offered Certificates will be represented initially by one or more global certificates registered in the name of a nominee of the Depository Trust Company in the United States, or of Clearstream and the Euroclear System (each, as defined in this free writing prospectus) in Europe and will be issued in minimum dollar denominations of $25,000 and integral multiples of $1.00 in excess thereof. See “Description of the Certificates-Book-Entry Certificates” in this free writing prospectus.

Class CE Certificates. The Class CE Certificates are not offered by this free writing prospectus. The Class CE Certificates will have an initial certificate principal balance of approximately $30,679,812 (subject to a permitted variance of plus or minus 10%), which represents approximately 3.70% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date.

Class P Certificates. The Class P Certificates are not offered by this free writing prospectus. The Class P Certificates will have an initial certificate principal balance of $100 and will not be entitled to distributions in respect of interest. The Class P Certificates will be entitled to all prepayment charges received in respect of the Mortgage Loans.

Residual Certificates. The Class R Certificates (the “Residual Certificates”) which are not offered by this free writing prospectus, represent the residual interests in the trust.

Credit Enhancement

The credit enhancement provided for the benefit of the holders of the Offered Certificates consists of excess interest, overcollateralization and subordination, each as described in this section and under “Description of the Certificates-Credit Enhancement” and “-Overcollateralization Provisions” in this free writing prospectus.

Excess Interest. The Mortgage Loans bear interest each month in an amount that in the aggregate is expected to exceed the amount needed to distribute monthly interest on the Offered Certificates and to pay certain fees and expenses of the trust and the supplemental interest trust (including any net swap payment payable to the swap provider and any swap termination payment payable to the swap provider which is not payable as a result of the occurrence of a swap provider trigger event). Any excess interest from the Mortgage Loans each month will be available to absorb realized losses on the Mortgage Loans and to maintain or restore overcollateralization at required levels.

Subordination. The rights of the holders of the Mezzanine Certificates and the Class CE Certificates to receive distributions will be subordinated, to the extent described in this free writing prospectus, to the rights of the holders of the Class A Certificates.

In addition, to the extent described under “Description of the Certificates—Allocation of Losses; Subordination” in this free writing prospectus,

• the rights of the holders of the Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9 and Class CE Certificates will be subordinated to the rights of the holders of the Class M-1 Certificates;

• the rights of the holders of the Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9 and Class CE Certificates will be subordinated to the rights of the holders of the Class M-2 Certificates;

• the rights of the holders of the Class M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9 and Class CE Certificates will be subordinated to the rights of the holders of the Class M-3 Certificates;

• the rights of the holders of the Class M-5, Class M-6, Class M-7, Class M-8, Class M-9 and Class CE Certificates will be subordinated to the rights of the holders of the Class M-4 Certificates;

• the rights of the holders of the Class M-6, Class M-7, Class M-8, Class M-9 and Class CE Certificates will be subordinated to the rights of the holders of the Class M-5 Certificates;

• the rights of the holders of the Class M-7, Class M-8, Class M-9 and Class CE Certificates will be subordinated to the rights of the holders of the Class M-6 Certificates;

• the rights of the holders of the Class M-8, Class M-9 and Class CE Certificates will be subordinated to the rights of the holders of the Class M-7 Certificates;

• the rights of the holders of the Class M-9 Certificates and Class CE Certificates will be subordinated to the rights of the holders of the Class M-8 Certificates; and

• the rights of the holders of the Class CE Certificates will be subordinated to the rights of the holders of the Class M-9 Certificates.

Subordination is intended to enhance the likelihood of regular distributions on the more senior certificates in respect of interest and principal and to afford the more senior certificates protection against realized losses on the Mortgage Loans, as described under “Description of the Certificates—Allocation of Losses; Subordination” in this free writing prospectus.

Overcollateralization. The aggregate principal balance of the Mortgage Loans as of the Cut-off Date will exceed the aggregate certificate principal balance of the Class A, Mezzanine and Class P Certificates on the Closing Date by approximately $30,679,812 (subject to a permitted variance of plus or minus 10%), which is equal to the initial Certificate Principal Balance of the Class CE Certificates. This amount represents approximately 3.70% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date, and is the initial amount of overcollateralization required to be provided by the mortgage pool under the pooling and servicing agreement. See “Description of the Certificates-Overcollateralization Provisions” in this free writing prospectus.

Allocation of Losses. If, on any Distribution Date, there is not sufficient excess interest, overcollateralization (represented by the Class CE Certificates) or net swap payments to absorb realized losses on the Mortgage Loans as described under “Description of the Certificates—Overcollateralization Provisions” in this free writing prospectus, then realized losses on the Mortgage Loans will be allocated to the Class M-9, Class M-8, Class M-7, Class M-6, Class M-5, Class M-4, Class M-3, Class M-2 and Class M-1 Certificates, in that order, in each case until the certificate principal balance of each such class has been reduced to zero. The pooling and servicing agreement does not permit the allocation of realized losses on the Mortgage Loans to the Class A Certificates; however, investors in the Class A Certificates should realize that under certain loss scenarios, there will not be enough principal and interest on the Mortgage Loans to pay the Class A Certificates all interest and principal amounts to which these certificates are then entitled. See “Description of the Certificates—Allocation of Losses; Subordination” in this free writing prospectus.

Unless the Servicer collects subsequent recoveries on Mortgage Loans for which realized losses were allocated to the Mezzanine Certificates, once realized losses are allocated to the Mezzanine Certificates, their certificate principal balances will be permanently reduced by the amount so allocated. However, the amount of any realized losses allocated to the Mezzanine Certificates may be distributed to the holders of those certificates according to the priorities set forth under “Description of the Certificates—Overcollateralization Provisions” in this free writing prospectus.

Cap Agreements

For each Distribution Date commencing in March 2007 and terminating immediately following the Distribution Date in August 2007, the Class A-1 Certificates and the Mezzanine Certificates will have the benefit of a cap agreement (the “Group I Cap Agreement”) provided by a cap provider having a long-term credit rating of at least “A+” (or the equivalent) from at least one of the rating agencies rating the Offered Certificates (the “Cap Provider”), which is intended partially to mitigate interest rate risk. The Group I Cap Agreement requires the Cap Provider to make a cap payment in an amount as described in this free writing prospectus.

For each Distribution Date commencing in March 2007 and terminating immediately following the Distribution Date in August 2007, the Class A-2 Certificates and the Mezzanine Certificates will have the benefit of a cap agreement (the “Group II Cap Agreement”) provided by the Cap Provider, which is intended partially to mitigate interest rate risk. The Group II Cap Agreement requires the Cap Provider to make a cap payment in an amount as described in this free writing prospectus.

Cap payments, if any, made by the Cap Provider will be deposited into a reserve fund and will be available for distribution on the related Class A Certificates and Mezzanine Certificates, in respect of any interest shortfall amounts resulting from the application of the applicable rate cap, to the limited extent described in this free writing prospectus. See “Description of the Certificates” and “—The Cap Agreements” in this free writing prospectus.

Interest Rate Swap Agreement

The Class A Certificates and the Mezzanine Certificates will have the benefit of an Interest Rate Swap Agreement (the “Interest Rate Swap Agreement”) provided by a swap provider having a long-term credit rating of at least “A+” (or the equivalent) from at least one of the rating agencies rating the Offered Certificates (the “Swap Provider”) for each Distribution Date commencing in September 2007 and ending immediately following the Distribution Date in February 2012, unless terminated earlier in accordance with the provisions of the Interest Rate Swap Agreement.

Pursuant to the Interest Rate Swap Agreement, on each Distribution Date, (i) the Securities Administrator (on behalf of a supplemental interest trust and from funds of such trust) will be obligated to pay to the Swap Provider, a fixed amount as described in this free writing prospectus (the “Securities Administrator Swap Payment”); and (ii) the Swap Provider will be obligated to pay to the supplemental interest trust for the benefit of the holders of the Class A Certificates and the Mezzanine Certificates (the “Swap Provider Payment”), a floating amount as described in this free writing prospectus.

A net payment will be required to be made on each Distribution Date (each such net payment, a “Net Swap Payment”) (a) by the Securities Administrator to the Swap Provider, to the extent that the Securities Administrator Payment exceeds the corresponding Swap Provider Payment, or (b) by the Swap Provider to the Securities Administrator, to the extent Swap Provider Payment exceeds the corresponding Securities Administrator Payment.

On each Distribution Date, if the Swap Provider is required to make a Net Swap Payment, such amount will be deposited into a reserve fund and will be available for distribution to the Class A Certificates and the Mezzanine Certificates in respect of any interest and principal shortfall amounts and any realized losses allocated to the Class A Certificates and Mezzanine Certificates as described in this free writing prospectus. If, on any Distribution Date, the Net Swap Payment with respect to the Class A Certificates and Mezzanine Certificates exceeds the amount of the interest and principal shortfall amounts and any realized losses allocated to the Class A Certificates and Mezzanine Certificates for such Distribution Date, after making the distributions set forth under “Description of the Certificates—The Interest Rate Swap Agreement” in this free writing prospectus, any remaining amounts will be distributed to the Class CE Certificates. See “Description of the Certificates—The Interest Rate Swap Agreement” in this free writing prospectus.

Upon early termination of the Interest Rate Swap Agreement, the Securities Administrator (on behalf of a supplemental interest trust and from funds of such trust) or the Swap Provider may be liable to make a termination payment (the “Swap Termination Payment”) to the other party (regardless of which party caused the termination). The Swap Termination Payment will be computed in accordance with the procedures set forth in the Interest Rate Swap Agreement. In the event that the Securities Administrator is required to make a Swap Termination Payment, that payment will be paid on the related Distribution Date, and on any subsequent Distribution Dates until paid in full, generally prior to any distribution to certificateholders. See “Description of the Certificates—The Interest Rate Swap Agreement” in this free writing prospectus.

Amounts payable by the Securities Administrator in respect of Net Swap Payments and Swap Termination Payments which are not payable as a result of the occurrence of a Swap Provider trigger event will be paid to the Swap Provider on each Distribution Date before distributions to certificateholders and will first be deposited to the supplemental interest trust before payment to the Swap Provider.

P&I Advances

The Servicer is required to advance delinquent payments of principal and interest on the Mortgage Loans, subject to the limitations described under “Description of the Certificates—P&I Advances” in this free writing prospectus. A successor servicer will be obligated to make any required delinquency advance if the Servicer fails in its obligation to do so, to the extent provided in the pooling and servicing agreement. The Servicer or any successor servicer, as the case may be, is entitled to be reimbursed for these advances, and therefore these advances are not a form of credit enhancement. See “Servicing of the Mortgage Loans—P&I Advances” in this free writing prospectus and “Description of the Securities—Advances in Respect of Delinquencies” in the prospectus.

Servicing Fee

With respect to each Mortgage Loan, the amount of the annual servicing fee that shall be paid to the Servicer is, for a period of one full month, equal to one-twelfth of the product of (a) 0.50% and (b) the outstanding principal balance of such Mortgage Loan. Such fee shall be payable monthly, computed on the basis of the same principal amount and period respecting which any related interest payment on such Mortgage Loan is computed. The obligation to pay the servicing fee is limited to, and the servicing fee is payable from the interest portion of such monthly payments collected; provided, however, that accrued and unpaid servicing fees applicable to liquidated mortgage loans may be payable out of amounts on deposit in the collection account as further described in the pooling and servicing agreement.

Master Servicing Fee

With respect to each Mortgage Loan, the amount of the annual master servicing fee that shall be paid to the Master Servicer is, for a period of one full month, equal to one-twelfth of the product of (a) 0.0035% and (b) the outstanding principal balance of such Mortgage Loan. Such fee shall be payable monthly, computed on the basis of the same principal amount and period respecting which any related interest payment on such Mortgage Loan is computed. The obligation to pay the master servicing fee is limited to, and the master servicing fee is payable from, the interest portion of such monthly payments collected. The Master Servicer will pay the trustee fee from its fee.

Credit Risk Manager’s Fee

With respect to each Mortgage Loan, the amount of the annual credit risk manager’s fee that shall be paid to the credit risk manager is a fee, for a period of one full month, equal to one-twelfth of the product of (a) 0.0135% and (b) the outstanding principal balance of such Mortgage Loan. Such fee will be payable monthly, computed on the basis of the same principal amount and period with respect to which any related interest payment on such Mortgage Loan is computed. The obligation to pay the credit risk manager’s fee will be limited to, and the credit risk manager’s fee will be payable from the interest portion of such monthly payments collected.

Optional Termination

At its option and subject to certain conditions, the Master Servicer may purchase all of the Mortgage Loans in the mortgage pool, together with any properties in respect of the Mortgage Loans acquired on behalf of the trust, and thereby effect termination and early retirement of the certificates, after the aggregate principal balance of the Mortgage Loans (and properties acquired in respect of the Mortgage Loans), remaining in the trust as of the last day of the related due period has been reduced to less than or equal to 10% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date. In the event the Master Servicer does not exercise such optional termination right, the Servicer may have the right, subject to certain conditions, to exercise such optional termination right. See “Pooling and Servicing Agreement—Termination” in this free writing prospectus and “Description of the Securities—Termination” in the prospectus.

Federal Income Tax Consequences

Multiple elections will be made to treat designated portions of the trust (exclusive of the reserve fund, the Cap Agreements, the Interest Rate Swap Agreement, payments from the supplemental interest trust or the obligation to make payments to the supplemental interest trust) as real estate mortgage investment conduits (each a “REMIC”) for federal income tax purposes. See “Material Federal Income Tax Considerations—REMICs —Characterization of Investments in REMIC Securities” in the prospectus.

For further information regarding the federal income tax consequences of investing in the Offered Certificates, see “Federal Income Tax Consequences” in this free writing prospectus and “Material Federal Income Tax Considerations” in the prospectus.

Ratings

It is a condition to the issuance of the certificates that the Offered Certificates receive at least the following ratings from Standard & Poor’s Ratings Service, a division of The McGraw-Hill Companies, Inc. (“S&P”) and Moody’s Investors Service, Inc. (“Moody’s”):

Offered Certificates	S&P	Moody’s
Class A-1	AAA	Aaa
Class A-2A	AAA	Aaa
Class A-2B	AAA	Aaa
Class A-2C	AAA	Aaa
Class A-2D	AAA	Aaa
Class M-1	AA+	Aa1
Class M-2	AA+	Aa2
Class M-3	AA	Aa3
Class M-4	AA	A1
Class M-5	AA-	A2
Class M-6	A+	A3
Class M-7	A-	Baa1
Class M-8	BBB+	Baa2
Class M-9	BBB	Baa3

A security rating does not address the frequency of prepayments on the Mortgage Loans or the corresponding effect on yield to investors. See “Yield on the Certificates” and “Ratings” in this free writing prospectus and “Yield Considerations” in the prospectus.

Legal Investment

The Offered Certificates will not constitute “mortgage related securities” for purposes of the Secondary Mortgage Market Enhancement Act of 1984. See “Legal Investment” in this free writing prospectus and in the prospectus.

Considerations for Benefit Plan Investors

It is expected that the Offered Certificates may be purchased by, or with the assets of, employee benefit plans subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or plans or arrangements (each, a “Plan”) subject to section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”). Prior to the termination of the supplemental interest trust, Plans or persons using assets of a Plan may purchase the Offered Certificates if the purchase and holding meets the requirements of an investor-based class exemption issued by the Department of Labor. Investors are encouraged to consult with their counsel with respect to the consequences under ERISA and the Code of a Plan’s acquisition and ownership of such certificates. See “Considerations for Benefit Plan Investors” in this free writing prospectus and “ERISA Considerations” in the prospectus.

TRANSACTION STRUCTURE

RISK FACTORS

The following information, which you should consider carefully, identifies significant risks associated with an investment in the certificates.

The Mortgage Loans were underwritten to standards which do not conform to the standards of Fannie Mae or Freddie Mac.

The underwriting standards applicable to the Mortgage Loans are intended to assess the ability and willingness of the mortgagor to repay the debt and to evaluate the adequacy of the property as collateral for the mortgage loan. In connection with the origination of the Mortgage Loans, among other things, a mortgagor’s credit history, repayment ability and debt service-to-income ratio, as well as the value, type and use of the mortgaged property are considered. As further described in this free writing prospectus, the underwriting standards applicable to the Mortgage Loans do not conform to Fannie Mae and Freddie Mac guidelines.

In addition, mortgage loans originated pursuant to the underwriting standards described in this free writing prospectus generally bear higher rates of interest than mortgage loans originated in accordance with Fannie Mae and Freddie Mac guidelines and may experience rates of delinquency, foreclosure and bankruptcy that are higher, and that may be substantially higher, than those experienced by mortgage loans underwritten in accordance with Fannie Mae and Freddie Mac guidelines.

Furthermore, changes in the values of mortgaged properties may have a greater effect on the delinquency, foreclosure, bankruptcy and loss experience of the Mortgage Loans than on mortgage loans originated in accordance with Fannie Mae and Freddie Mac guidelines. No assurance can be given that the values of the related mortgaged properties have remained or will remain at the levels in effect on the dates of origination of the related Mortgage Loans. See “The Mortgage Pool—DB-ASAP Program Description and Underwriting Standards” in this free writing prospectus.

Mortgage Loans with high combined loan-to-value ratios leave the related mortgagor with little or no equity in the related mortgaged property.

Approximately 47.38% of the Group I Mortgage Loans and approximately 30.58% of the Group II Mortgage Loans, in each case, by the related aggregate principal balance as of the Cut-off Date, had a combined loan-to-value ratio at origination in excess of 80%.

An overall decline in the residential real estate market, a rise in interest rates over a period of time and the condition of a mortgaged property, as well as other factors, may have the effect of reducing the value of the mortgaged property from the appraised value at the time the Mortgage Loan was originated. If there is a reduction in the value of the mortgaged property, the combined loan-to-value ratio may increase over what it was at the time the Mortgage Loan was originated. Such an increase may reduce the likelihood of liquidation or other proceeds being sufficient to satisfy the Mortgage Loan, and any losses to the extent not covered by the credit enhancement may affect the yield to maturity of your certificates. There can be no assurance that the value of a mortgaged property estimated in any appraisal or review is equal to the actual value of that mortgaged property at the time of that appraisal or review. Investors should note that the values of the mortgaged properties may be insufficient to cover the outstanding principal balance of the Mortgage Loans. There can be no assurance that the combined loan-to-value ratio of any Mortgage Loan determined at any time after origination will be less than or equal to its combined loan-to-value ratio at origination.

Developments in specified states could have a disproportionate effect on the Mortgage Loans due to the geographic concentration of the mortgaged properties.

Approximately 15.47%, 10.15%, 8.64%, 5.66%, 5.09%, and 5.03% of the Group I Mortgage Loans, by aggregate principal balance of the Group I Mortgage Loans as of the Cut-off Date, are secured by mortgaged properties located in the State of California, the State of Florida, the State of Arizona, the State of Minnesota, the State of Illinois, and the State of Michigan, respectively, and approximately 44.24% and 10.63% of the Group II Mortgage Loans, by aggregate principal balance of the Group II Mortgage Loans as of the Cut-off Date, are secured by mortgaged properties located in the State of California and the State of Florida, respectively. Approximately 0.74% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date, are located in a single California zip code. If the residential real estate market in these states should experience an overall decline in property values after the dates of origination of the related Mortgage Loans, the rates of delinquencies, foreclosures, bankruptcies and losses on the Mortgage Loans may increase over historical levels of comparable type loans, and may increase substantially. In addition, properties located in California and Florida may be more susceptible than homes located in other parts of the country to certain types of uninsured hazards, such as earthquakes, hurricanes, as well as floods, mudslides and other natural disasters.

Second Lien Mortgage Loans Risk.

Approximately 4.40% of the Group I Mortgage Loans and approximately 7.80% of the Group II Mortgage Loans, in each case, by the related aggregate principal balance as of the Cut-off Date, are secured by second liens on the related mortgaged properties. The proceeds from any liquidation, insurance or condemnation proceedings will be available to satisfy the outstanding balance of such Mortgage Loans only to the extent that the claims of the related senior mortgages have been satisfied in full, including any related foreclosure costs. In circumstances when it has been determined to be uneconomical to foreclose on the mortgaged property, the Servicer may write off the entire balance of such Mortgage Loan as a bad debt. The foregoing considerations will be particularly applicable to Mortgage Loans secured by second liens that have high combined loan-to-value ratios because it is comparatively more likely that the Servicer would determine foreclosure to be uneconomical in the case of such Mortgage Loans. The rate of default of second lien Mortgage Loans may be greater than that of mortgage loans secured by first liens on comparable properties.

Balloon Mortgage Loan Risk.

Mortgage Loans that are balloon loans pose a risk because a borrower must make a large lump sum payment of principal at the end of the loan term. If the borrower is unable to pay the lump sum or refinance such amount, the Servicer will not be obligated to advance the principal portion of that lump sum payment, you may suffer a loss. Approximately 30.08% of the Group I Mortgage Loans and approximately 25.16% of the Group II Mortgage Loans, in each case, by related aggregate principal balance as of the Cut-off Date, are balloon loans.

Interest Only Mortgage Loan Risk.

Approximately 26.90% of the Group I Mortgage Loans and approximately 44.34% of the Group II Mortgage Loans, in each case, by the related aggregate principal balance as of the Cut-off Date, require the borrowers to make monthly payments only of accrued interest for the five or ten years following origination. After such interest-only period, the borrower’s monthly payment will be recalculated to cover both interest and principal so that the Mortgage Loan will amortize fully prior to its final payment date. If the monthly payment increases, the related borrower may not be able to pay the increased amount and may default or may refinance the related Mortgage Loan to avoid the higher payment. Because no principal payments may be made or advanced on such Mortgage Loans for five or ten years following origination, the certificateholders will receive smaller principal distributions during such period than they would have received if the related borrowers were required to make monthly payments of interest and principal for the entire lives of such Mortgage Loans. This slower rate of principal distributions may reduce the return on an investment in the Offered Certificates that are purchased at a discount.

The Mezzanine Certificates will be more sensitive to losses on the Mortgage Loans than the Class A Certificates because they are subordinate to the Class A Certificates.

The weighted average lives of, and the yields to maturity on, the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates will be progressively more sensitive, in that order, to the rate and timing of mortgagor defaults and the severity of ensuing losses on the Mortgage Loans. If the actual rate and severity of losses on the Mortgage Loans is higher than those assumed by an investor in these certificates, the actual yield to maturity of these certificates may be lower than the yield anticipated by the investor based on such assumption. The timing of losses on the Mortgage Loans will also affect an investor’s actual yield to maturity, even if the rate of defaults and severity of losses over the life of the mortgage pool are consistent with an investor’s expectations. In general, the earlier a loss occurs, the greater the effect on an investor’s yield to maturity. Realized losses on the Mortgage Loans, to the extent they exceed the amount of excess interest, overcollateralization and Net Swap Payments received from the Swap Provider in respect of the Interest Rate Swap Agreement, will reduce the certificate principal balances of the Mezzanine Certificates beginning with the class of Mezzanine Certificates then outstanding with the lowest payment priority. As a result of such reductions, less interest will accrue on each such class of Mezzanine Certificates than would otherwise be the case. However, the amount of any realized losses allocated to the Mezzanine Certificates may be distributed to the holders of those certificates according to the priorities set forth under “Description of the Certificates—Overcollateralization Provisions” and “Description of the Certificates—The Interest Rate Swap Agreement” in this free writing prospectus.

The Mezzanine Certificates generally will not be entitled to receive principal payments until March 2010 which may result in a greater risk of loss relating to these certificates.

Unless the aggregate certificate principal balance of the Class A Certificates has been reduced to zero, the Mezzanine Certificates will not be entitled to any principal distributions until at least March 2010 or a later date as provided in this free writing prospectus or during any period in which delinquencies on the Mortgage Loans exceed the levels set forth under “Description of the Certificates—Principal Distributions on the Offered Certificates” in this free writing prospectus. As a result, the weighted average lives of the Mezzanine Certificates will be longer than would be the case if distributions of principal were allocated among all of the certificates at the same time. As a result of the longer weighted average lives of the Mezzanine Certificates, the holders of these certificates have a greater risk of suffering a loss on their investments. Further, because such certificates might not receive any principal if the delinquency levels set forth under “Description of the Certificates—Principal Distributions on the Offered Certificates” in this free writing prospectus are exceeded, it is possible for such certificates to receive no principal distributions on a particular Distribution Date even if no losses have occurred on the mortgage pool.

The Offered Certificates will be limited obligations solely of the Issuing Entity and not of any other party.

The Offered Certificates will not represent an interest in or obligation of the Sponsor, the Depositor, the Servicer, the Master Servicer, the Securities Administrator, the Originator, the Trustee or any of their respective affiliates. Neither the Offered Certificates nor the underlying Mortgage Loans will be guaranteed or insured by any governmental agency or instrumentality, or by the Sponsor, the Depositor, the Servicer, the Master Servicer, the Securities Administrator, the Originator, the Trustee or any of their respective affiliates. Proceeds of the assets included in the trust and the supplemental interest trust will be the sole source of payments on the Offered Certificates, and there will be no recourse to the Sponsor, the Depositor, the Servicer, the Originator, the Master Servicer, the Securities Administrator, the Trustee or any other entity in the event that these proceeds are insufficient or otherwise unavailable to make all payments provided for under the Offered Certificates.

The difference between the pass-through rates on the Class A Certificates and Mezzanine Certificates and the mortgage rates on the Mortgage Loans may result in interest shortfalls on such certificates.

The yield to maturity on the Class A Certificates and the Mezzanine Certificates may be affected by the resetting of the mortgage rates on the adjustable-rate Mortgage Loans included in the mortgage pool on their related adjustment dates. In addition, because the mortgage rates for the adjustable-rate Mortgage Loans adjust based on Six-Month LIBOR plus a fixed percentage amount, such rate could be higher than prevailing market interest rates, and this may result in an increase in the rate of prepayments on such Mortgage Loans after their adjustments. Finally, the mortgage rates on the adjustable-rate Mortgage Loans are based on Six-Month LIBOR while the pass-through rates on the Class A Certificates and the Mezzanine Certificates are based on One-Month LIBOR. Consequently, the application to such certificates of the rate cap, which is generally equal to the weighted average coupon on the related Mortgage Loans, net of certain fees of the trust and the supplemental interest trust (including any Net Swap Payment payable to the Swap Provider and any swap termination payment payable to the Swap Provider which is not payable as a result of the occurrence of a Swap Provider trigger event), could adversely affect the yield to maturity on such certificates. In addition, the rate cap will decrease if Mortgage Loans with relatively high mortgage rates prepay at a faster rate than Mortgage Loans with relatively low mortgage rates.

If the pass-through rates on the Class A Certificates or the Mezzanine Certificates are limited for any Distribution Date, the resulting interest shortfalls may be recovered by the holders of these certificates on the same Distribution Date or on future Distribution Dates on a subordinated basis to the extent that the Cap Provider is required to make any cap payments on such Distribution Date and to the extent that on such Distribution Date or future Distribution Dates there are available funds remaining after certain other distributions on the Class A Certificates and Mezzanine Certificates and the payment of certain fees and expenses of the trust and the supplemental interest trust (including any Net Swap Payment payable to the Swap Provider and any swap termination payment payable to the Swap Provider which is not payable as a result of the occurrence of a Swap Provider trigger event). The ratings on the Offered Certificates will not address the likelihood of any recovery of interest shortfalls by holders of the Offered Certificates from amounts collected on the Mortgage Loans. See “Yield on the Certificates—Special Yield Considerations” in this free writing prospectus.

As further described in this free writing prospectus, amounts used to pay such interest shortfalls on the Class A Certificates and Mezzanine Certificates may be supplemented by the Interest Rate Swap Agreement to the extent that the floating payment required to be made by the Swap Provider exceeds the fixed payment required to be made by the Securities Administrator (on behalf of the supplemental interest trust) on any Distribution Date and such amount is available in the priority described in this free writing prospectus. However, the amount received from the Swap Provider under the Interest Rate Swap Agreement may be insufficient to pay the holders of the Class A Certificates and Mezzanine Certificates the full amount of interest which they would have received absent the limitations of the rate cap.

The rate and timing of principal distributions on the Class A Certificates and the Mezzanine Certificates will be affected by prepayment speeds and by the priority of payment on such certificates.

The rate and timing of distributions allocable to principal on the Class A Certificates and the Mezzanine Certificates will depend, in general, on the rate and timing of principal payments (including prepayments and collections upon defaults, liquidations and repurchases) on the Mortgage Loans and the allocation thereof to pay principal on such certificates as described in “Description of the Certificates—Principal Distributions on the Offered Certificates” in this free writing prospectus. As is the case with mortgage backed pass-through certificates generally, the Offered Certificates are subject to substantial inherent cash-flow uncertainties because the Mortgage Loans may be prepaid at any time. However, with respect to approximately 79.90% of the Mortgage Loans, by aggregate principal balance of the Mortgage Loans as of the Cut-off Date, a prepayment may subject the related mortgagor to a prepayment charge. A prepayment charge may or may not act as a deterrent to prepayment of the related Mortgage Loan. See “The Mortgage Pool” in this free writing prospectus.

Generally, when prevailing interest rates are increasing, prepayment rates on mortgage loans tend to decrease; a decrease in the prepayment rates on the Mortgage Loans will result in a reduced rate of return of principal to investors in the Class A Certificates and the Mezzanine Certificates at a time when reinvestment at such higher prevailing rates would be desirable. Conversely, when prevailing interest rates are declining, prepayment rates on mortgage loans tend to increase; an increase in the prepayment rates on the Mortgage Loans will result in a greater rate of return of principal to investors in the Class A Certificates and the Mezzanine Certificates at a time when reinvestment at comparable yields may not be possible.

Distributions of principal will be made to the holders of the Mezzanine Certificates according to the priorities described in this free writing prospectus. The timing of commencement of principal distributions and the weighted average life of each such class of certificates will be affected by the rates of prepayment on the Mortgage Loans experienced both before and after the commencement of principal distributions on such classes. For further information regarding the effect of principal prepayments on the weighted average lives of the Offered Certificates, see “Yield on the Certificates” in this free writing prospectus, including the tables entitled “Percent of Initial Certificate Principal Balance Outstanding at the Specified Percentages of the Prepayment Assumption.”

The yield to maturity on the Offered Certificates will depend on a variety of factors.

The yield to maturity on the Offered Certificates will depend on:

the applicable pass-through rate thereon;

the applicable purchase price;

the rate and timing of principal payments (including prepayments and collections upon defaults, liquidations and repurchases) and the allocation thereof to reduce the certificate principal balance of the Offered Certificates;

the rate, timing and severity of realized losses on the Mortgage Loans, adjustments to the mortgage rates on the adjustable-rate Mortgage Loans included in the mortgage pool, the amount of excess interest generated by the Mortgage Loans and the allocation to the Offered Certificates of certain interest shortfalls; and

payments due from the supplemental interest trust in respect of payments received from the Swap Provider under the Interest Rate Swap Agreement.

In general, if the Offered Certificates are purchased at a premium and principal distributions thereon occur at a rate faster than anticipated at the time of purchase, the investor’s actual yield to maturity will be lower than that assumed at the time of purchase. Conversely, if the Offered Certificates are purchased at a discount and principal distributions thereon occur at a rate slower than that anticipated at the time of purchase, the investor’s actual yield to maturity will be lower than that originally assumed.

The proceeds to the Depositor from the sale of the Offered Certificates were determined based on a number of assumptions, including a prepayment assumption of 100% PPC (based on the assumed prepayment rates set forth under “Yield on the Certificates—Weighted Average Lives” in this free writing prospectus) with respect to the adjustable-rate Mortgage Loans and a prepayment assumption of 100% PPC (based on the assumed prepayment rates set forth under “Yield on the Certificates—Weighted Average Lives” in this free writing prospectus) with respect to the fixed-rate Mortgage Loans, and weighted average lives corresponding thereto. No representation is made that the Mortgage Loans will prepay at such rate or at any other rate. The yield assumptions for the Offered Certificates will vary as determined at the time of sale.

The yield to maturity on the Mezzanine Certificates will be particularly sensitive to the rate of prepayments on the Mortgage Loans.

The multiple class structure of the Mezzanine Certificates causes the yield of these classes to be particularly sensitive to changes in the rates of prepayment of the Mortgage Loans. Because distributions of principal will be made to the holders of such certificates according to the priorities described in this free writing prospectus, the yield to maturity on such classes of certificates will be sensitive to the rates of prepayment on the Mortgage Loans experienced both before and after the commencement of principal distributions on such classes. The yield to maturity on such classes of certificates will also be extremely sensitive to losses due to defaults on the Mortgage Loans (and the timing thereof), to the extent these losses are not covered by excess cashflow otherwise payable to the Class CE Certificates, Net Swap Payments received under the Interest Rate Swap Agreement or allocated to a class of Mezzanine Certificates with a lower payment priority. Furthermore, as described in this free writing prospectus, the timing of receipt of principal and interest by the Mezzanine Certificates may be adversely affected by losses even if these classes of certificates do not ultimately bear such loss.

Violation of consumer protection laws may result in losses on the Mortgage Loans and your certificates.

Applicable state laws generally regulate interest rates and other charges, require certain disclosure, and require licensing of originators of mortgage loans. In addition, other state laws, public policy and general principles of equity relating to the protection of consumers, unfair and deceptive practices and debt collection practices may apply to the origination, servicing and collection of the Mortgage Loans.

The Mortgage Loans are also subject to federal laws, including:

the Federal Truth-in-Lending Act and Regulation Z promulgated thereunder, which require certain disclosures to the mortgagors regarding the terms of the Mortgage Loans;

the Equal Credit Opportunity Act and Regulation B promulgated thereunder, which prohibit discrimination on the basis of age, race, color, sex, religion, marital status, national origin, receipt of public assistance or the exercise of any right under the Consumer Credit Protection Act, in the extension of credit;

the Fair Credit Reporting Act, which regulates the use and reporting of information related to the mortgagor’s credit experience; and

the Depository Institutions Deregulation and Monetary Control Act of 1980, which preempts certain state usury laws.

Violations of certain provisions of these federal and state laws may limit the ability of the Servicer to collect all or part of the principal of or interest on the related Mortgage Loans and in addition could subject the trust to damages and administrative enforcement. In particular, the failure of the originator to comply with certain requirements of the Federal Truth-in-Lending Act, as implemented by Regulation Z, could subject the trust to monetary penalties, and result in the mortgagors’ rescinding the Mortgage Loans against the trust. In addition to federal law, some states have enacted, or may enact, laws or regulations that prohibit inclusion of some provisions in Mortgage Loans that have interest rates or origination costs in excess of prescribed levels, and require that mortgagors be given certain disclosures prior to the consummation of the Mortgage Loans and restrict the Servicer’s ability to foreclose in response to mortgagor defaults. The failure of the Originator to comply with these laws could subject the trust to significant monetary penalties, could result in the mortgagors rescinding the Mortgage Loans against the trust and/or limit the Servicer’s ability to foreclose upon the related mortgaged properties in the event of mortgagor defaults.

Under the anti-predatory lending laws of some states, the mortgagor is required to meet a net tangible benefits test in connection with the origination of the related mortgage loan. This test may be highly subjective and open to interpretation. As a result, a court may determine that a mortgage loan does not meet the test even if the Originator reasonably believed that the test was satisfied. Any determination by a court that a Mortgage Loan included in the trust fund does not meet the test will result in a violation of the state anti-predatory lending law, in which case the Sponsor will be required to purchase that Mortgage Loan from the trust fund.

The Sponsor will represent that, as of the Closing Date, each Mortgage Loan is in compliance with applicable federal and state laws and regulations. In the event of a breach of such representation, the Sponsor will be obligated to cure such breach or repurchase or replace the affected Mortgage Loan in the manner described in the prospectus. If the Sponsor is unable or otherwise fails to satisfy such obligations, the yield on the Offered Certificates may be materially and adversely affected.

Your distributions could be adversely affected by the bankruptcy or insolvency of certain parties.

The Sponsor will treat the transfer of the Mortgage Loans to the Depositor as a sale of the Mortgage Loans. However, if the Sponsor becomes bankrupt, the trustee in bankruptcy may argue that the Mortgage Loans were not sold but were only pledged to secure a loan to the Sponsor. If that argument is made, you could experience delays or reductions in payments on the certificates. If that argument is successful, the bankruptcy trustee could elect to sell the Mortgage Loans and pay down the certificates early. Thus, you could lose the right to future payments of interest, and might suffer reinvestment loss in a lower interest rate environment.

In addition, if the Master Servicer becomes bankrupt, a bankruptcy trustee or receiver may have the power to prevent the appointment of a successor Master Servicer. Any related delays in servicing could result in increased delinquencies or losses on the Mortgage Loans.

Interest generated by the Mortgage Loans may be insufficient to maintain or restore overcollateralization.

The Mortgage Loans are expected to generate more interest than is needed to pay interest owed on the Offered Certificates and to pay certain fees and expenses of the trust and the supplemental interest trust (including any Net Swap Payment payable to the Swap Provider and any swap termination payment payable to the Swap Provider which is not payable as a result of the occurrence of a Swap Provider trigger event). Any remaining interest generated by the Mortgage Loans will then be used to absorb losses that occur on the Mortgage Loans. After these financial obligations of the trust are covered, available excess interest generated by the Mortgage Loans will be used to maintain or restore the overcollateralization. We cannot assure you, however, that enough excess interest will be generated to maintain or restore the required level of overcollateralization. The factors described below will affect the amount of excess interest that the Mortgage Loans will generate:

Every time a Mortgage Loan is prepaid in full, excess interest may be reduced because such Mortgage Loan will no longer be outstanding and generating interest or, in the case of a partial prepayment, will be generating less interest.

Every time a Mortgage Loan is liquidated or written off, excess interest may be reduced because such Mortgage Loan will no longer be outstanding and generating interest.

If the rates of delinquencies, defaults or losses on the Mortgage Loans are higher than expected, excess interest will be reduced by the amount necessary to compensate for any shortfalls in cash available to make required distributions on the Offered Certificates.

The adjustable-rate Mortgage Loans have mortgage rates that adjust less frequently than, and on the basis of indices that are different from, the index used to determine the pass-through rates on the Offered Certificates, and the fixed-rate Mortgage Loans have mortgage rates that do not adjust. As a result, the pass-through rates on the Offered Certificates may increase relative to mortgage rates on the Mortgage Loans, requiring that a greater portion of the interest generated by the Mortgage Loans be applied to cover interest on such certificates.

Interest payments on the Mortgage Loans may be insufficient to pay interest on your certificates.

When a Mortgage Loan is prepaid in full, the mortgagor is charged interest only up to the date on which payment is made, rather than for an entire month. This may result in a shortfall in interest collections available for payment on the next Distribution Date. The Servicer is required to cover a portion of the shortfall in interest collections that are attributable to voluntary prepayments in full on the Mortgage Loans received during the portion of the related Prepayment Period occurring from the sixteenth day of the month prior to the month in which the related Distribution Date occurs through the last day of such month, but only up to the servicing fee payable to the Servicer for the related interest accrual period. In addition, if the Servicer fails to pay all or a portion of these amounts, the Master Servicer is required to pay such amounts up to the compensation payable to the Master Servicer for the related due period. If the credit enhancement is insufficient to cover this shortfall in excess of the amount the Servicer or the Master Servicer covers, you may incur a loss. In addition, the Servicer will not be required to cover shortfalls in interest collections due to bankruptcy proceedings or the application of the Servicemembers Civil Relief Act (the “Relief Act”) or similar state or local laws.

On any Distribution Date, any shortfalls resulting from the application of the Relief Act or similar state or local laws and any prepayment interest shortfalls to the extent not covered by compensating interest paid by the Servicer or the Master Servicer will be allocated, first, to the Class CE Certificates, second, to the Class M-9 Certificates, third, to the Class M-8 Certificates, fourth, to the Class M-7 Certificates, fifth, to the Class M-6 Certificates, sixth, to the Class M-5 Certificates, seventh, to the Class M-4 Certificates, eighth, to the Class M-3 Certificates, ninth, to the Class M-2 Certificates, tenth, to the Class M-1 Certificates and eleventh, to the Class A Certificates, on a pro rata basis, based on their respective senior interest distribution amounts for such Distribution Date before such reduction. The holders of the Class A Certificates and Mezzanine Certificates will be entitled to reimbursement for any such interest shortfalls but only to the extent of available funds and amounts payable by the Swap Provider under the Interest Rate Swap Agreement, and in the order of priority set forth under “Description of the Certificates—Overcollateralization Provisions” and “Description of the Certificates—The Interest Rate Swap Agreement” in this free writing prospectus. If these shortfalls are allocated to the Class A Certificates or Mezzanine Certificates the amount of interest paid to those certificates will be reduced, adversely affecting the yield on your investment.

The liquidity of your certificates may be limited.

The Underwriter has no obligation to make a secondary market in the classes of Offered Certificates. There is therefore no assurance that a secondary market will develop or, if it develops, that it will continue. 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 certificates are likely to fluctuate; these fluctuations may be significant and could result in significant losses to you.

The secondary markets for asset-backed securities have experienced periods of illiquidity and can be expected to 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, or that have been structured to meet the investment requirements of limited categories of investors.

The Cap Agreements are Subject to Counterparty Risk.

The assets of the trust include two separate Cap Agreements which will require the Cap Provider to make certain payments for the benefit of the holders of the Class A Certificates and Mezzanine Certificates. To the extent that distributions on the Class A Certificates and Mezzanine Certificates depend in part on payments to be received by the Securities Administrator under the Cap Agreements, the ability of the Securities Administrator to make such distributions on the related Class A Certificates and Mezzanine Certificates will be subject to the credit risk of the Cap Provider. Although there is a mechanism in place to facilitate replacement of the Cap Agreements upon the default or credit impairment of the Cap Provider, there can be no assurance that any such mechanism will result in the ability of the Trustee to obtain suitable replacement Cap Agreements.

The Interest Rate Swap Agreement and the Swap Provider.

Any amounts received from the Swap Provider under the Interest Rate Swap Agreement will be applied as described in this free writing prospectus to pay current and carryforward interest, maintain or restore the required level of overcollateralization, cover realized losses on the Mortgage Loans allocated to the Mezzanine Certificates and pay any Net WAC Rate Carryover Amounts (as defined in this free writing prospectus under “Description of the Certificates—Glossary”) to the Class A Certificates and Mezzanine Certificates. However, no amounts will be payable by the Swap Provider unless the floating amount owed by the Swap Provider on a Distribution Date exceeds the fixed amount owed to the Swap Provider on such Distribution Date. This will generally not occur except in periods when one-month LIBOR (as determined pursuant to the Interest Rate Swap Agreement) exceeds _____% per annum. No assurance can be made that any amounts will be received under the Interest Rate Swap Agreement, or that any such amounts that are received will be sufficient to pay current and carryforward interest, maintain or restore the required level of overcollateralization, cover realized losses on the Mortgage Loans allocated to the Mezzanine Certificates or pay any Net WAC Rate Carryover Amounts. Any Net Swap Payment payable to the Swap Provider under the terms of the Interest Rate Swap Agreement will reduce amounts available for distribution to certificateholders, and may reduce the pass-through rates of the certificates. The combination of a rapid rate of prepayment and low prevailing interest rates could adversely affect the yields on the Class A Certificates and Mezzanine Certificates. In addition, any swap termination payment payable to the Swap Provider in the event of early termination of the Interest Rate Swap Agreement which was not caused by the occurrence of a Swap Provider trigger event will reduce amounts available for distribution to certificateholders.

Upon early termination of the Interest Rate Swap Agreement, the Securities Administrator (on behalf of the supplemental interest trust) or the Swap Provider may be liable to make a Swap Termination Payment to the other party (regardless of which party caused the termination). The Swap Termination Payment will be computed in accordance with the procedures set forth in the Interest Rate Swap Agreement. In the event that the Securities Administrator (on behalf of the supplemental interest trust) is required to make a Swap Termination Payment, that payment will be paid on the related Distribution Date, and on any subsequent Distribution Dates, until paid in full, generally prior to distributions to certificateholders. This feature may result in losses on the certificates. Due to the priority of the application of the available distribution amount, the Mezzanine Certificates will bear the effects of any shortfalls resulting from a Net Swap Payment or Swap Termination Payment by the Securities Administrator before such effects are borne by the Class A Certificates and therefore, one or more classes of Mezzanine Certificates may suffer a loss as a result of such payment.

To the extent that distributions on the Class A Certificates and Mezzanine Certificates depend in part on payments to be received by the Securities Administrator (on behalf of the supplemental interest trust) under the Interest Rate Swap Agreement, the ability of the Securities Administrator to make such distributions on the Class A Certificates and Mezzanine Certificates will be subject to the credit risk of the Swap Provider. Although there is a mechanism in place to facilitate replacement of the Interest Rate Swap Agreement upon the default or credit impairment of the Swap Provider, there can be no assurance that any such mechanism will result in the ability of the trustee to obtain a suitable replacement interest rate swap agreement. The credit ratings of the Swap Provider may be lower than the ratings assigned to the Class A Certificates. See “Description of the Certificates—The Interest Rate Swap Agreement” in this free writing prospectus.

The return on your certificates could be reduced by shortfalls due to the application of the Relief Act.

The Relief Act and similar state or local laws provide relief to mortgagors who enter active military service and to mortgagors in reserve status who are called to active military service after the origination of their mortgage loans. The ongoing military operations of the United States in Iraq and Afghanistan have caused an increase in the number of citizens in active military duty, including those citizens previously in reserve status. Under the Relief Act the interest rate applicable to a mortgage loan for which the related mortgagor is called to active military service will be reduced from the percentage stated in the related mortgage note to 6.00%. This interest rate reduction and any reduction provided under similar state or local laws could result in an interest shortfall because the Master Servicer and the Servicer will not be able to collect the amount of interest which otherwise would be payable with respect to such Mortgage Loan if the Relief Act or similar state or local law was not applicable thereto. This shortfall will not be paid by the mortgagor on future due dates or advanced by the Master Servicer or the Servicer and, therefore, will reduce the amount available to pay interest to the certificateholders on subsequent Distribution Dates. We do not know how many Mortgage Loans in the mortgage pool have been or may be affected by the application of the Relief Act or similar state or local law.

Possible reduction or withdrawal of ratings on the Offered Certificates.

Each rating agency rating the Offered Certificates may change or withdraw its initial ratings at any time in the future if, in its judgment, circumstances warrant a change. No person is obligated to maintain the ratings at their initial levels. If a rating agency reduces or withdraws its rating on one or more classes of the Offered Certificates, the liquidity and market value of the affected certificates is likely to be reduced.

Suitability of the Offered Certificates as investments.

The Offered Certificates are not suitable investments for any investor that requires a regular or predictable schedule of monthly payments or payment on any specific date. The Offered Certificates are complex investments that should be considered only by investors who, either alone or with their financial, tax and legal advisors, have the expertise to analyze the prepayment, reinvestment, default and market risk, the tax consequences of an investment and the interaction of these factors.

FICO scores are not an indicator of future performance of mortgagors.

Investors are encouraged to be aware that FICO scores are based on past payment history of the mortgagor. Investors are encouraged not to rely on FICO scores as an indicator of future borrower performance. See “The Mortgage Pool—DB-ASAP Program Description and Underwriting Standards” in this free writing prospectus.

Recent Developments in the Residential Mortgage Market May Adversely Affect the Performance and Market Value of Your Securities.

Recently, the residential mortgage market in the United States has experienced a variety of difficulties and changed economic conditions that may adversely affect the performance and market value of your securities. Delinquencies and losses with respect to residential mortgage loans generally have increased in recent months, and may continue to increase, particularly in the subprime sector. In addition, in recent months housing prices and appraisal values in many states have declined or stopped appreciating, after extended periods of significant appreciation. A continued decline or an extended flattening of those values may result in additional increases in delinquencies and losses on residential mortgage loans generally, particularly with respect to second homes and investor properties and with respect to any residential mortgage loans whose aggregate loan amounts (including any subordinate liens) are close to or greater than the related property values.

In addition, numerous residential mortgage loan originators that originate subprime mortgage loans have recently experienced serious financial difficulties and, in some cases, bankruptcy. Those difficulties have resulted in part from declining markets for mortgage loans as well as from claims for repurchases 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 the mortgage loans, such as fraud claims. The inability to repurchase these loans in the event of early payment defaults or breaches of representations and warranties may also affect the performance and market value of your securities.

The Mortgage Loans in the trust fund include subprime mortgage loans, and it is possible that an Originator, due to substantial economic exposure to the subprime mortgage market, for financial or other reasons may not be capable of repurchasing or substituting for any defective mortgage loans in the trust fund. You should consider that the general market conditions discussed above may adversely affect the performance and market value of your securities.

Foreclosure Restrictions May Increase Realized Losses.

Any Mortgage Loans that are 60 or more days delinquent based on the terms of the original mortgage note, modification, bankruptcy plan or forbearance plan as of the close of business on March 1, 2007 may have certain restrictions placed on their foreclosure in the pooling and servicing agreement. In the event that foreclosure proceedings are commenced with respect to one of these Mortgage Loans, if acquiring title to the related mortgaged property would cause the adjusted basis (for federal income tax purposes) of the mortgaged properties that are currently owned by the related REMIC after foreclosure (along with any other assets owned by that REMIC other than “qualified mortgages” and “permitted investments” within the meaning of Section 860G of the Internal Revenue Code) to exceed 0.75% of the adjusted basis of the assets in the related REMIC, the Servicer will not be permitted to acquire title to the Mortgage Loan on behalf of such REMIC. Instead, the Servicer must dispose of the Mortgage Loan for cash in the foreclosure sale. In addition, if the Servicer determines that following a distribution on any Distribution Date the adjusted basis of such mortgaged properties in foreclosure (along with any other assets owned by the related REMIC other than “qualified mortgages” and “permitted investments” within the meaning of Section 860G of the Internal Revenue Code) exceeds 1.0% of the adjusted basis of the assets of the related REMIC immediately after the distribution, then prior to such Distribution Date, the Servicer will be required to dispose of enough of such mortgaged properties in foreclosure, for cash, so that the adjusted basis of such mortgaged properties in foreclosure (along with any other assets owned by the related REMIC other than “qualified mortgages” and “permitted investments” within the meaning of Section 860G of the Internal Revenue Code) will be less than 1.0% of the adjusted basis of the assets of the related REMIC. In either event, the Servicer will be permitted to acquire (for its own account and not on behalf of the trust fund) the mortgaged property at the foreclosure sale for an amount not less than the greater of: (i) the highest amount bid by any other person at the foreclosure sale, or (ii) the estimated fair value of the mortgaged property, as determined by the Servicer in good faith. These restrictions will be lifted with respect to a delinquent Mortgage Loan if such Mortgage Loan becomes current for three consecutive regular scheduled monthly payments. As a result of these restrictions, losses on these Mortgage Loans may be greater than if the Servicer was permitted to obtain title on behalf of the trust fund. In the case of those Mortgage Loans subject to such further restrictions, realized losses may be greater than would be the case if such Mortgage Loans were not subject to such further restrictions.

All capitalized terms used in this free writing prospectus will have the meanings assigned to them under “Description of the Certificates—Glossary” or in the prospectus under “Index of Defined Terms.”

USE OF PROCEEDS

DB Structured Products, Inc. (the “Sponsor”), will sell the Mortgage Loans to ACE Securities Corp. (the “Depositor”) and the Depositor will convey the Mortgage Loans to the trust fund in exchange for and concurrently with the delivery of the certificates. Net proceeds from the sale of the Offered Certificates will be applied by the Depositor to the purchase of the Mortgage Loans from the Sponsor. Such net proceeds together with certain classes of certificates not offered by this free writing prospectus will represent the purchase price to be paid by the Depositor to the Sponsor for the Mortgage Loans. The Mortgage Loans were previously purchased by the Sponsor directly from various third-party originators who originated the Mortgage Loans in accordance with the Sponsor’s underwriting guidelines.

THE MORTGAGE POOL

General

All percentages and amounts with respect to the characteristics of the Mortgage Loans shown in this free writing prospectus are subject to a permitted variance of plus or minus 10%.

The pool of mortgage loans (the “Mortgage Pool”) will consist of 4,657 conventional, one- to four-family, first and second lien, fixed-rate and adjustable-rate mortgage loans (the “Mortgage Loans”) on residential real properties (the “Mortgaged Properties”) having an aggregate principal balance as of the Cut-off Date of approximately $829,214,912 after application of scheduled payments due on or before the Cut-off Date whether or not received. The Mortgage Loans have original terms to maturity of not greater than 30 years. For purposes of calculating interest and principal distributions on the Class A Certificates, the Mortgage Loans have been divided into two loan groups, designated as the “Group I Mortgage Loans” and the “Group II Mortgage Loans.” The Group I Mortgage Loans consist of 2,479 fixed-rate and adjustable-rate mortgage loans having an aggregate principal balance as of the Cut-off Date of approximately $364,444,648 after application of scheduled payments due on or before the Cut-off Date whether or not received. The principal balances of the Group I Mortgage Loans at origination conformed to Freddie Mac loan limits. The Group II Mortgage Loans consist of 2,178 fixed-rate and adjustable-rate mortgage loans having an aggregate principal balance as of the Cut-off Date of approximately $464,770,264 after application of scheduled payments due on or before the Cut-off Date whether or not received. The principal balances of the Group II Mortgage Loans at origination may or may not have conformed to Freddie Mac or Fannie Mae loan limits.

Approximately 43.02% and 30.50% of the Group I Mortgage Loans and Group II Mortgage Loans, in each case by related aggregate principal balance as of the Cut-off Date, provide for level monthly payments in an amount sufficient fully to amortize the Mortgage Loans over their terms or, in the case of adjustable rate Mortgage Loans, monthly payments that will be adjusted to an amount that will amortize such Mortgage Loans fully over their terms. Approximately 30.08% and 25.16% of the Group I Mortgage Loans and Group II Mortgage Loans, in each case by related aggregate principal balance as of the Cut-off Date, are balloon loans (the “Balloon Loans”), which require the related mortgagors to make balloon payments on the maturity date of such Balloon Loans that are larger than the monthly payments made by such mortgagors on prior due dates in order to amortize such Balloon Loans fully over their terms. Approximately 26.90% and 44.34% of the Group I Mortgage Loans and Group II Mortgage Loans, in each case by related aggregate principal balance as of the Cut-off Date, are interest only loans (the “Interest Only Loans”) which require the related mortgagors to make monthly payments of only accrued interest for the first five or ten years following origination. After such interest-only period, the mortgagor’s monthly payment will be recalculated to cover both interest and principal so that such Mortgage Loan will amortize fully on or prior to its final payment date.

Approximately 95.60% and 92.20% of the Group I Mortgage Loans and Group II Mortgage Loans, in each case by related aggregate principal balance as of the Cut-off Date, are secured by first mortgages or deeds of trust or other similar security instruments creating first liens on residential properties (“First Lien Mortgage Loans”). Approximately 4.40% and 7.80% of the Group I Mortgage Loans and Group II Mortgage Loans, in each case by related aggregate principal balance as of the Cut-off Date, are secured by second mortgages or deeds of trust or other similar security instruments creating second liens on residential properties (“Second Lien Mortgage Loans”). The Mortgaged Properties generally consist of attached, detached or semi detached, one-to-four family dwelling units, individual condominium units, individual units in planned unit developments, and modular units, rowhouses and townhouses.

References to percentages of the Mortgage Loans, unless otherwise noted, are calculated based on the aggregate principal balance of the Mortgage Loans as of the Cut-off Date.

The mortgage rate (the “Mortgage Rate”) on each Mortgage Loan is the per annum rate of interest specified in the related mortgage note as reduced by application of the Relief Act or similar state or local laws and bankruptcy adjustments. Approximately 21.61% and 24.13% of the Group I Mortgage Loans and Group II Mortgage Loans, in each case by related aggregate principal balance as of the Cut-off Date, are fixed-rate mortgage loans and approximately 78.39% and 75.87% of the Group I Mortgage Loans and Group II Mortgage Loans, in each case by related aggregate principal balance as of the Cut-off Date, are adjustable-rate mortgage loans. The adjustable-rate mortgage loans are referred to in this free writing prospectus as “ARM Loans”. All of the ARM Loans provide for semi-annual adjustment to the Mortgage Rates applicable thereto based on Six-Month LIBOR (as described below). The first adjustment with respect to each ARM Loan will not occur until after an initial period of six months or one, two, three or five years from the date of origination thereof (each, a “Delayed First Adjustment Mortgage Loan”). In connection with each Mortgage Rate adjustment, the ARM Loans have corresponding adjustments to their monthly payment amount, in each case on each applicable adjustment date (each such date, an “Adjustment Date”). As to each Mortgage Loan, the Servicer will be responsible for calculating and implementing Mortgage Rate adjustments. On each Adjustment Date, the Mortgage Rate on each ARM Loan will be adjusted generally to equal the sum of Six-Month LIBOR and a fixed percentage amount (the “Gross Margin”) for that ARM Loan specified in the related mortgage note. The Mortgage Rate on each ARM Loan, however, including each Delayed First Adjustment Mortgage Loan, will not increase or decrease by more than the initial periodic rate cap (the “Initial Periodic Rate Cap”) specified in the related mortgage note on the initial Adjustment Date or increase or decrease by more than the subsequent periodic rate cap (the “Subsequent Periodic Rate Cap”) specified in the related mortgage note on any subsequent Adjustment Date and will not exceed a specified maximum mortgage rate (the “Maximum Mortgage Rate”) over the life of the ARM Loan or be less than a specified minimum mortgage rate (the “Minimum Mortgage Rate”) over the life of the ARM Loan. The weighted average Initial Periodic Rate Cap and Subsequent Periodic Rate Cap for the ARM Loans is approximately 2.985% per annum and approximately 1.002% per annum, respectively. Effective with the first monthly payment due on each ARM Loan after each related Adjustment Date, the monthly payment amount on each ARM Loan (other than any ARM Loan which is a Balloon Loan) will be adjusted to an amount that will fully amortize the outstanding principal balance of the related ARM Loan over its remaining term and pay interest at the Mortgage Rate as so adjusted. Due to the application of the Periodic Rate Caps and the Maximum Mortgage Rates, the Mortgage Rate on each ARM Loan, as adjusted on any related Adjustment Date, may be less than the sum of the Six-Month LIBOR, calculated as described in this free writing prospectus, and the related Gross Margin. See ��—The Index” in this free writing prospectus. None of the ARM Loans permit the related mortgagor to convert the adjustable Mortgage Rate thereon to a fixed Mortgage Rate.

Substantially all of the Mortgage Loans have scheduled monthly payments due on the first day of the month (with respect to each Mortgage Loan, the “Due Date”). Each Mortgage Loan will contain a customary “due-on-sale” clause which provides that the Mortgage Loan must be repaid at the time of a sale of the related Mortgaged Property or assumed by a creditworthy purchaser of the related Mortgaged Property.

Approximately 80.10% and 79.74% of the Group I Mortgage Loans and Group II Mortgage Loans, in each case by related aggregate principal balance as of the Cut-off Date, provide for payment by the mortgagor of a prepayment charge (a “Prepayment Charge”) in limited circumstances on certain prepayments as provided in the related mortgage note. Each such Mortgage Loan provides for payment of a Prepayment Charge on certain partial prepayments and all prepayments in full made within a certain period of time from the date of origination of the Mortgage Loan, as provided in the related mortgage note. The amount of the Prepayment Charge is as provided in the related mortgage note. The holders of the Class P Certificates will be entitled to all Prepayment Charges received on the Mortgage Loans, and these amounts will not be available for distribution on the other classes of certificates. Under the limited instances described under the terms of the pooling and servicing agreement, the Servicer may waive the payment of any otherwise applicable Prepayment Charge with respect to the related Mortgage Loans. As of July 1, 2003, the Alternative Mortgage Parity Act of 1982 (the “Parity Act”), which regulates the ability of originators to impose Prepayment Charges, was amended, and as a result, the originators will be required to comply with state and local laws in originating mortgage loans with Prepayment Charge provisions with respect to loans originated on or after July 1, 2003. The Depositor makes no representations as to the effect that the Prepayment Charges and the amendment of the Parity Act may have on the prepayment performance of the Mortgage Loans. However, the amendment of the Parity Act does not retroactively affect loans originated before July 1, 2003. Investors should conduct their own analysis of the effect, if any, that the Prepayment Charges, decisions by the Servicer with respect to the waiver of the Prepayment Charges and the amendment to the Parity Act, may have on the prepayment performance of the Mortgage Loans. The Depositor makes no representation as to the effect that the Prepayment Charges, decisions by the servicer with respect to the waiver of the Prepayment Charges and the amendment to the Parity Act, may have on the prepayment performance of the Mortgage Loans. See “Certain Legal Aspects of the Mortgage Loans-Prepayment Charges and Late Fees; Debt-Acceleration Clauses” in the prospectus.

In addition, the Servicer may waive the collection of any otherwise applicable Prepayment Charge, but only if: (i) such waiver is standard and customary in servicing similar Mortgage Loans and such waiver is related to a default or reasonably foreseeable default and would, in the reasonable judgment of the Servicer maximize recovery of total proceeds taking into account the value of such Prepayment Charge and the related Mortgage Loan and, if such waiver is made in connection with a refinancing of the related Mortgage Loan, such refinancing is related to a default or a reasonably foreseeable default, (ii) such Prepayment Charge is unenforceable in accordance with applicable law or the collection of such related Prepayment Charge would otherwise violate applicable law or (iii) the collection of such Prepayment Charge would be considered “predatory” pursuant to written guidance published or issued by any applicable federal, state or local regulatory authority acting in its official capacity and having jurisdiction over such matters.

Approximately 0.79% of the Mortgage Loans will be 30-59 days delinquent as of the Cut-off Date. No Mortgage Loan will be more than 60 days delinquent as of the Cut-off Date. The following table sets forth the historical delinquency experience of the Mortgage Loans. A Mortgage Loan is considered to be delinquent when a payment due on any Due Date remains unpaid as of the close of business on the next monthly Due Date. The determination as to whether a Mortgage Loan falls into this category is made as of the close of business on the last business day of each month. The historical delinquency information is based on the delinquency of each such Mortgage Loan since the date on which such Mortgage Loans were purchased by the Sponsor, which ranges from zero to eleven months prior to the Cut-off Date. The Sponsor and the Depositor are unable to provide the delinquency information as of origination of the Mortgage Loans without unreasonable effort or expense because neither the Sponsor nor the Depositor was the owner of the Mortgage Loans prior to the date such Mortgage Loans were purchased by the Sponsor, the prior owner of such Mortgage Loans is not affiliated with the Sponsor or the Depositor and the owner was not the servicer of such Mortgage Loans and therefore, was not in a position to track or monitor the delinquency status of such Mortgage Loans.

Mortgage Loan Characteristics

The average principal balance of the Mortgage Loans at origination was approximately $178,197. No Mortgage Loan had a principal balance at origination greater than approximately $1,480,000 or less than approximately $10,300. The average principal balance of the Mortgage Loans as of the Cut-off Date was approximately $178,058. No Mortgage Loan had a principal balance as of the Cut-off Date greater than approximately $1,480,000 or less than approximately $10,295.

The Mortgage Loans had Mortgage Rates as of the Cut-off Date ranging from approximately 5.125% per annum to approximately 16.750% per annum, and the weighted average Mortgage Rate was approximately 8.116% per annum. As of the Cut-off Date, the ARM Loans had Gross Margins ranging from approximately 2.250% per annum to approximately 8.260% per annum, Minimum Mortgage Rates ranging from approximately 2.750% per annum to approximately 14.625% per annum and Maximum Mortgage Rates ranging from approximately 11.250% per annum to approximately 20.625% per annum. As of the Cut-off Date, the weighted average Gross Margin was approximately 5.697% the weighted average Minimum Mortgage Rate was approximately 8.038% per annum and the weighted average Maximum Mortgage Rate was approximately 14.057% per annum. The latest first Adjustment Date following the Cut-off Date on any ARM Loan occurs on February 1, 2012 and the weighted average next Adjustment Date for all of the ARM Loans following the Cut-off Date is March 3, 2009.

The weighted average combined loan-to-value ratio of the Mortgage Loans at origination was approximately 83.14%. At origination, no Mortgage Loan had a combined loan-to-value ratio greater than approximately 100.00% or less than approximately 15.09%.

The weighted average remaining term to stated maturity of the Mortgage Loans was approximately 347 months as of the Cut-off Date. None of the Mortgage Loans will have a first due date prior to February 1, 2006 or after March 1, 2007 or will have a remaining term to stated maturity of less than approximately 113 months or greater than approximately 360 months as of the Cut-off Date. The latest maturity date of any Mortgage Loan is 360.

As of the Cut-off Date, the weighted average FICO Score for the Mortgage Loans that were scored is approximately 649. No Mortgage Loan which was scored had a FICO Score as of the Cut-off Date greater than 815 or less than 492.

The Mortgage Loans are expected to have the following additional characteristics as of the Cut-off Date (the sum in any column may not equal the total indicated due to rounding):

The Index

As of any Adjustment Date, the index applicable to the determination of the Mortgage Rate on the ARM Loans will generally be the average of the interbank offered rates for six-month United States dollar deposits in the London market as published in The Wall Street Journal and as most recently available either (i) as of the first business day 45 days prior to that Adjustment Date or (ii) as of the first business day of the month preceding the month of the Adjustment Date, as specified in the related mortgage note (“Six-Month LIBOR” or the “Index”). In the event that the Index becomes unavailable or otherwise unpublished, the Servicer will select a comparable alternative index over which it has no direct control and which is readily verifiable.

General. All of the Mortgage Loans were acquired by the Depositor from the Sponsor. The Mortgage Loans were originated by various third party originators pursuant to the underwriting standard described in this section and were reviewed by the Sponsor to ensure conformity with such underwriting standards. The Sponsor’s underwriting standards are primarily intended to assess the ability and willingness of a borrower to repay the debt of the mortgage loan and to evaluate the adequacy of the related mortgaged property as collateral for the mortgage loan. All of the Mortgage Loans were underwritten with a view towards resale in the secondary mortgage market. In underwriting a mortgage loan, the Sponsor considers, among other things, a mortgagor's credit history, repayment ability and debt service-to-income ratio (referred to in this section of the free writing prospectus as the “Debt Ratio”), as well as the value, type and use of the mortgaged property. The Mortgage Loans generally were not originated in accordance with Fannie Mae and Freddie Mac standards. Unless prohibited by state law or otherwise waived by the Sponsor upon the payment by the related mortgagor of higher origination fees and a higher Mortgage Rate, the related Mortgage Loan generally provides for the payment by the mortgagor of a prepayment charge on certain full or partial prepayments made within one to three years from the date of origination of the related Mortgage Loan.

Qualifications of DB-ASAP Program Sellers. All of the mortgage loans purchased by the Sponsor are based on loan application packages submitted by approved mortgage companies (the “DB-ASAP Program Sellers”). The DB-ASAP Program Sellers must meet minimum standards set by the Sponsor based on an analysis of the following information submitted with an application for approval: applicable state lending license (in good standing) federal income tax identification number, executed mortgage loan sale agreement, signed W-9 and signed seller authorization. Once approved, the DB-ASAP Program Sellers are eligible to submit loan application packages in compliance with the terms of the executed DB-ASAP sale agreement.

DB-ASAP Program Underwriting Guidelines. The Sponsor has one underwriting program called the DB-ASAP Program. The DB-ASAP Program was developed to simplify the origination process for the DB-ASAP Program Sellers, and uses Credit Bureau Risk Scores to this end. In contrast to assignment of credit grades according to traditional non-agency credit assessment methods, i.e., mortgage and other credit delinquencies, the Sponsor relies upon a borrower's Credit Bureau Risk Score initially to determine a borrower's likely future credit performance. DB-ASAP Program Sellers are able to access Credit Bureau Risk Scores at the initial phases of the loan application process and use the score to determine a borrower's interest rate based upon the DB-ASAP Program risk-based pricing matrix (subject to final loan approval by the Sponsor).

Credit Bureau Risk Scores are statistical rankings of likely future credit performance developed by Fair, Isaac & Company and the three national credit repositories -- Equifax, Trans Union and First American (formerly Experian which was formerly TRW). The Credit Bureau Risk Scores available from the three national credit repositories are calculated by the assignment of weightings to the most predictive data collected by the credit repositories and range from 300 to 850. Although the Credit Bureau Risk Scores are based solely on the information at the particular credit repository, such Credit Bureau Risk Scores have been calibrated to indicate the same level of credit risk regardless of which credit repository is used. The Credit Bureau Risk Score is used by the underwriter as an aid, and does not substitute for the underwriter's judgment.

Under the DB-ASAP Program, the Sponsor requires that the Credit Bureau Risk Score of the primary borrower (the borrower with at least 51.00% of total income for all loan-to-value ratios) be used to determine program eligibility. Credit Bureau Risk Scores must be obtained from at least two national credit repositories, with the lower of the two scores being utilized in program eligibility determination. If Credit Bureau Risk Scores are obtained from three credit repositories, the middle of the three scores can be utilized. In all cases, a borrower's complete credit history must be detailed in the credit report that produces a given Credit Bureau Risk Score or the mortgage loan is not eligible for the DB-ASAP Program. Generally, the minimum Credit Bureau Risk Score allowed under the DB-ASAP Full Documentation Program and Limited Documentation Verification Program is 540. Generally, the minimum Credit Bureau Risk Score allowed under the DB-ASAP No Income Verification Program is 560. Generally, the minimum Credit Bureau Risk Score allowed under the DB-ASAP No Documentation Program is 660.

The applicant generally must have a sufficiently established credit history to qualify for the appropriate Credit Bureau Risk Score range under the DB-ASAP Program. This credit history is substantiated by a three repository merged report prepared by an independent credit report agency. The report typically summarizes the applicant's entire credit history, and generally includes a seven year public record search for each address where the applicant has lived during the two years prior to the issuance of the credit report and contains information relating to such matters as credit history with local and national merchants and lenders, installment debt payments and any record of defaults, bankruptcy, repossession, suits or judgments. In some instances, borrowers with a minimal credit history are eligible for financing under the DB-ASAP Program.

The Credit Bureau Risk Score, along with the loan-to-value ratio, is an important tool in assessing the creditworthiness of a borrower. However, these two factors are not the only considerations in underwriting a loan. The Sponsor’s contracted underwriting staff fully reviews each loan to determine whether the Sponsor's guidelines for income, assets, employment and collateral are met.

All of the Mortgage Loans were reviewed by the Sponsor’s contract underwriters. On a case by case basis, the Sponsor may determine that, based upon compensating factors, a prospective borrower who does not strictly qualify under the underwriting risk category guidelines described below warrants an underwriting exception. Compensating factors may include, but are not limited to, low loan-to-value ratio, low Debt Ratio, substantial liquid assets, good credit history, stable employment and time in residence at the applicant's current address. It is expected that an insignificant portion of the Mortgage Loans may represent such underwriting exceptions.

Within the DB-ASAP Program, there are five documentation programs: the Full Documentation Program, the Limited Documentation Verification Program, the Stated Extra Program, the No Income Verification Program and the No Documentation Program. All of the Mortgage Loans were originated in accordance with the Sponsor's DB-ASAP Program.

The Sponsor's contract underwriters review the income of each applicant under various documentation programs as follows: under the Full Documentation Program, applicants are generally required to submit verification of stable income for the periods of one to two years preceding the application dependent on credit score range; under the Limited Documentation Verification Program, the borrower is qualified based on the income stated on the application and applicants are generally required to submit verification of adequate cash flow to meet credit obligations for the six month period preceding the application; the Stated Extra Program allows income to be stated, but requires borrowers provide verification of liquid assets equaling three months of income stated on the mortgage application; under the No Income Verification Program, applicants are qualified based on monthly income as stated on the mortgage application and the underwriter will determine that the stated income is reasonable and realistic when compared to borrower's employment type, assets and credit history. The No Documentation Program requires no employment, no income and no assets verification.

For first lien mortgage loans from self-employed or 1099 borrowers with a credit score greater than or equal to 560 and not originated in conjunction with a second lien mortgage, bank statements (for 12 months) are acceptable as full documentation. For first lien mortgage loans from self-employed or 1099 borrowers with credit scores greater than or equal to 580, regardless of being originated with a corresponding second lien mortgage, twelve months bank statements are acceptable as full documentation. In all cases, the income stated must be reasonable and customary for the applicant's line of work. Income is not verified under the Limited Documentation Verification Program and No Income Verification Program.

The Sponsor also offers ASAP-Refi which allows reduced income documentation in exchange for timely payments of a current mortgage over the previous eighteen (18) month period.

The Sponsor acquires mortgage loans secured by 1-4 unit residential properties made to eligible borrowers with a vested fee simple (or in some cases a leasehold) interest in the property. The Sponsor's guidelines are applied in accordance with a procedure which complies with applicable federal and state laws and regulations and generally require an appraisal of the mortgaged property which conforms to Freddie Mac and/or Fannie Mae standards and, if appropriate, a review appraisal. Generally, appraisals are provided by an approved list of appraisers maintained by the Sponsor. Additionally, review appraisals may only be provided by appraisers other than the original appraiser approved by the Sponsor. In some cases, the Sponsor relies on a statistical appraisal methodology provided by a third-party.

Each review appraisal includes a market data analysis based on recent sales of comparable homes in the area and, where deemed appropriate, replacement cost analysis based on the current cost of constructing a similar home. The review appraisal may be an enhanced desk, field review or an automated valuation report that confirms or supports the original appraiser's value of the mortgaged premises.

The Sponsor requires title insurance on all mortgage loans secured by liens on real property. The Sponsor also requires that fire and extended coverage casualty insurance be maintained on the secured property in an amount at least equal to the principal balance of the related residential loan or the replacement cost of the property, whichever is less.

The Sponsor conducts a number of quality control procedures, including a full re-underwriting of a random selection of mortgage loans to assure asset quality. Under the asset quality procedure, a random selection of each month's originations is reviewed. The mortgage loan review confirms the existence and accuracy of legal documents, credit documentation, appraisal analysis and underwriting decision. A report detailing audit findings and level of error is sent monthly to management for response. The audit findings and management responses are then reviewed by the Sponsor's senior management. Adverse findings are tracked monthly and over a rolling six month period. This review procedure allows the Sponsor to assess programs for potential guideline changes, program enhancements, appraisal policies, areas of risk to be reduced or eliminated and the need for additional staff training.

Under the DB-ASAP Program, various risk categories are used to grade the likelihood that the applicant will satisfy the repayment conditions of the loan. These risk categories establish the maximum permitted loan-to-value ratio and loan amount, given the occupancy status of the mortgaged property and the applicant's credit history and Debt Ratio. In general, higher credit risk mortgage loans are graded in categories which permit higher Debt Ratios and more (or more recent) major derogatory credit items such as outstanding judgments or recent foreclosure proceedings; however these loan programs establish lower maximum loan-to-value ratios and lower maximum loan amounts for mortgage loans graded in such categories.

The Sponsor's guidelines under the DB-ASAP Program generally have the following criteria for borrower eligibility for the specified Credit Bureau Risk Score range.

The Debt Ratio generally may not exceed 50.49% for all credit scores on Full Documentation Program and Limited Income Verification Program mortgage loans. Loans meeting the residual income requirements may have a maximum Debt Ratio of 55.49%. The Debt Ratio for No Income Verification Program mortgage loans may not exceed 50.49%.

Generally, all liens affecting title must be paid at closing. Collections, charge-offs, judgments and liens not affecting title may remain open for mortgage loans with loan-to-value ratios less than or equal to 80%, provided certain criteria are met. For instance, if the mortgage loan is a purchase or rate and term refinance, a payoff of such amount will not be required if (i) the related loan is not being originated together with a second lien loan, (ii) the balance of the items(s) added to the mortgage loan amount does not exceed the maximum allowed combined loan-to-value ratio, (iii) the payment amounts are included in the debt calculation (iv) and the mortgage loan has first lien priority.

Additional Information Concerning the Mortgage Loans

The description in this free writing prospectus of the Mortgage Pool and the Mortgaged Properties is based upon the Mortgage Pool as constituted as of the close of business on the Cut-off Date, as adjusted for the scheduled principal payments due on or before such date. Prior to the issuance of the certificates, Mortgage Loans may be removed from the Mortgage Pool as a result of incomplete documentation or otherwise if the Depositor deems the removal necessary or desirable, and may be prepaid at any time. A limited number of other mortgage loans may be included in the Mortgage Pool prior to the issuance of the certificates unless including these mortgage loans would materially alter the characteristics of the Mortgage Pool as described in this free writing prospectus. The Depositor believes that the information set forth in this free writing prospectus will be representative of the characteristics of the Mortgage Pool as it will be constituted at the time the certificates are issued, although the range of Mortgage Rates and maturities and other characteristics of the Mortgage Loans may vary.

YIELD ON THE CERTIFICATES

General Prepayment Considerations

The rate of principal payments on the Offered Certificates, the aggregate amount of distributions on such certificates and the yield to maturity of such certificates will be related to the rate and timing of payments of principal on the Mortgage Loans. The rate of principal payments on the Mortgage Loans will in turn be affected by the amortization schedules of the Mortgage Loans as they change from time to time to accommodate changes in the Mortgage Rates and by the rate of principal prepayments thereon (including for this purpose, payments resulting from refinancings, liquidations of the Mortgage Loans due to defaults, casualties, condemnations and repurchases, whether optional or required, by the Depositor, the Servicer or the Sponsor). The Mortgage Loans may be prepaid by the mortgagors at any time; however, as described under “The Mortgage Pool” in this free writing prospectus, with respect to approximately 79.90% of the Mortgage Loans, by aggregate principal balance of the Mortgage Loans as of the Cut-off Date, a prepayment may subject the related mortgagor to a Prepayment Charge.

Prepayments, liquidations and repurchases of the Mortgage Loans will result in distributions in respect of principal to the holders of the class or classes of Offered Certificates then entitled to receive distributions that otherwise would be distributed over the remaining terms of the Mortgage Loans. Since the rates of payment of principal on the Mortgage Loans will depend on future events and a variety of factors, no assurance can be given as to that rate or the rate of principal prepayments. The extent to which the yield to maturity of any class of Offered Certificates may vary from the anticipated yield will depend upon the degree to which the Offered Certificates are purchased at a discount or premium and the degree to which the timing of payments thereon is sensitive to prepayments on the Mortgage Loans. Further, an investor should consider, in the case of any Offered Certificate purchased at a discount, the risk that a slower than anticipated rate of principal payments on the Mortgage Loans could result in an actual yield to the investor that is lower than the anticipated yield. In the case of any Offered Certificate purchased at a premium, there is a risk that a faster than anticipated rate of principal payments could result in an actual yield to the investor that is lower than the anticipated yield. In general, the earlier prepayments of principal are made on the Mortgage Loans, the greater the effect on the yield to maturity of the Offered Certificates. As a result, the effect on an investors’ yield of principal payments occurring at a rate higher (or lower) than the rate anticipated by the investor during the period immediately following the issuance of the Offered Certificates would not be fully offset by a subsequent like reduction (or increase) in the rate of principal payments.

It is highly unlikely that the Mortgage Loans will prepay at any constant rate until maturity or that all of the Mortgage Loans will prepay at the same rate. Moreover, the timing of prepayments on the Mortgage Loans may significantly affect the yield to maturity on the Offered Certificates, even if the average rate of principal payments experienced over time is consistent with an investor’s expectation.

The rate of payments (including prepayments) on pools of mortgage loans is influenced by a variety of economic, geographic, social and other factors. If prevailing mortgage rates fall significantly below the Mortgage Rates on the Mortgage Loans, the rate of prepayment and refinancing would be expected to increase. Conversely, if prevailing mortgage rates rise significantly above the Mortgage Rates on the Mortgage Loans, the rate of prepayment on the Mortgage Loans would be expected to decrease. Other factors affecting prepayment of mortgage loans include changes in mortgagors’ housing needs, job transfers, unemployment, mortgagors’ net equity in the mortgaged properties and servicing decisions. The prepayment experience of the Delayed First Adjustment Mortgage Loans may differ from that of the other Mortgage Loans. The Delayed First Adjustment Mortgage Loans may be subject to greater rates of prepayments as they approach their initial Adjustment Dates even if market interest rates are only slightly higher or lower than the Mortgage Rates on the Delayed First Adjustment Mortgage Loans as mortgagors seek to avoid changes in their monthly payments. In addition, the existence of the applicable Periodic Rate Cap, Maximum Mortgage Rate and Minimum Mortgage Rate may affect the likelihood of prepayments resulting from refinancings. There can be no certainty as to the rate of prepayments on the Mortgage Loans during any period or over the life of the certificates. See “Yield Considerations” in the prospectus.

Because principal distributions are paid to certain classes of Offered Certificates before other classes, holders of classes of Offered Certificates having a later priority of payment bear a greater risk of losses than holders of classes having earlier priorities for distribution of principal. This is because the certificates having a later priority of payment will represent an increasing percentage interest in the trust fund during the period prior to the commencement of distributions of principal on these certificates. As described under “Description of the Certificates—Principal Distributions on the Offered Certificates” in this free writing prospectus, prior to the Stepdown Date, all principal payments on the Mortgage Loans will be allocated to the Class A Certificates. Thereafter, as further described in this free writing prospectus, during certain periods, subject to certain delinquency triggers described in this free writing prospectus, all principal payments on the Mortgage Loans will be allocated among the Class A Certificates and all classes of the Mezzanine Certificates in the priorities described under “Description of the Certificates—Principal Distributions on the Offered Certificates” in this free writing prospectus.

In general, defaults on mortgage loans are expected to occur with greater frequency in their early years. In addition, default rates may be higher for mortgage loans used to refinance an existing mortgage loan. In the event of a mortgagor’s default on a Mortgage Loan, there can be no assurance that recourse will be available beyond the specific Mortgaged Property pledged as security for repayment. See “The Mortgage Pool—DB-ASAP Program Description and Underwriting Standards” in this free writing prospectus.

Special Yield Considerations

The Mortgage Rates on approximately 23.03% of the Mortgage Loans, by aggregate principal balance as of the Cut-off Date, are fixed and will not vary with any index. The Mortgage Rates on approximately 76.97% of the Mortgage Loans, by aggregate principal balance as of the Cut-off Date, adjust semi-annually based upon Six-Month LIBOR, subject to periodic and lifetime limitations and after an initial period of six months, one, two, three or five years with respect to Delayed First Adjustment Mortgage Loans. The Pass-Through Rate on the Offered Certificates adjusts monthly based upon One-Month LIBOR, subject to the applicable Net WAC Pass-Through Rate (as defined under “Description of the Certificates—Glossary” in this free writing prospectus), with the result that increases in the Pass-Through Rates on such certificates may be limited for extended periods in a rising interest rate environment. Investors should note that all of the ARM Loans are Delayed First Adjustment Mortgage Loans. The interest due on the Mortgage Loans during any Due Period, net of the expenses of the trust and the supplemental interest trust (including any Net Swap Payment and any Swap Termination Payment payable to the Swap Provider which was not caused by the occurrence of a Swap Provider Trigger Event), may not equal the amount of interest that would accrue at One-Month LIBOR plus the applicable spread on the Offered Certificates during the related Interest Accrual Period; however, any shortfall of this kind will be payable to the holders of such certificates, but only to the extent and in the priority described under “Description of the Certificates—Overcollateralization Provisions”, “Description of the Certificates—The Interest Rate Swap Agreement” and “Description of the Certificates—The Cap Agreements” in this free writing prospectus. In addition, Six-Month LIBOR and One-Month LIBOR may respond differently to economic and market factors. Thus, it is possible, for example, that if One-Month LIBOR and Six-Month LIBOR rise during the same period, One-Month LIBOR may rise more rapidly than Six-Month LIBOR, potentially resulting in the application of the applicable Net WAC Pass-Through Rate on the Offered Certificates, which would adversely affect the yield to maturity on such certificates.

If the pass-through rates on the Offered Certificates are limited by the applicable Net WAC Pass-Through Rate for any Distribution Date, the resulting interest shortfalls, which are referred to in this free writing prospectus as “Net WAC Rate Carryover Amounts”, may be recovered by the holders of such certificates on such Distribution Date or on future Distribution Dates, to the extent that the Cap Provider is required to make any cap payments on such Distribution Date and to the extent that on such Distribution Date or future Distribution Dates there are any available funds remaining after certain other distributions on the Offered Certificates and the payment of certain fees and expenses of the trust and the supplemental interest trust (including any Net Swap Payment payable to the Swap Provider and any Swap Termination Payment payable to the Swap Provider which was not caused by the occurrence of a Swap Provider Trigger Event). The ratings on the Offered Certificates will not address the likelihood of any such recovery of such interest shortfalls by holders of those certificates from amounts received or advanced on the Mortgage Loans. In addition, any Net Swap Payment payable by the Swap Provider on any given Distribution Date will be available to pay any Net WAC Rate Carryover Amounts remaining unpaid on such Distribution Date after taking into account any amounts paid in respect thereof from collections, advances and other recoveries on the Mortgage Loans.

As described under “Description of the Certificates—Allocation of Losses; Subordination,” amounts otherwise distributable to holders of the Mezzanine Certificates and the Class CE Certificates may be made available to protect the holders of the Class A Certificates against interruptions in distributions due to certain mortgagor delinquencies, to the extent not covered by P&I Advances. Such delinquencies may affect the yield to investors in the Mezzanine Certificates and, even if subsequently cured, will affect the timing of the receipt of distributions by the holders of the Mezzanine Certificates. In addition, the rate of delinquencies or losses will affect the rate of principal payments on the Mezzanine Certificates. See “Description of the Certificates—Principal Distributions on the Offered Certificates” in this free writing prospectus.

Weighted Average Lives

Weighted average life refers to the average amount of time that will elapse from the date of issuance of a security until each dollar of principal of that security will be repaid to the investor. The weighted average life of the Offered Certificates will be influenced by the rate at which principal on the Mortgage Loans is paid, which may be in the form of scheduled payments or prepayments (including repurchases and prepayments of principal by the mortgagor as well as amounts received by virtue of condemnation, insurance or foreclosure with respect to the Mortgage Loans), and the timing of these payments. The “Scheduled Final Distribution Date” for each class of the Offered Certificates is the Distribution Date occurring in March 2037. The Scheduled Final Distribution Date is the Distribution Date in the month following the latest scheduled maturity date of all of the Mortgage Loans. Since the rate of payment (including prepayments) of principal on the Mortgage Loans can be expected to exceed the scheduled rate of payments, and could exceed the scheduled rate by a substantial amount, the disposition of the last remaining Mortgage Loan may be earlier, and could be substantially earlier, than the Scheduled Final Distribution Date.

Prepayments on mortgage loans are commonly measured relative to a prepayment standard or model. The prepayment assumption used in this free writing prospectus with respect to the adjustable-rate Mortgage Loans assumes a prepayment rate for the mortgage loans of 100% PPC. To assume 100% PPC is to assume (i) a per annum prepayment rate of 5% of the then outstanding principal balance of the mortgage loans in the first month of the life of the mortgage loans, (ii) an additional 2% per annum in each month thereafter through the eleventh month, (iii) building to a constant prepayment rate of 27% per annum beginning in the twelfth month and remaining constant until the twenty-third month, (iv) increasing to and remaining constant at a prepayment rate of 60% per annum beginning in the twenty-fourth month until the twenty-seventh month and (v) decreasing and remaining constant at a prepayment rate of 30% per annum from the twenty-eighth month and thereafter; provided, however, the prepayment rate will not exceed 85% per annum in any period for any percentage of PPC. The prepayment assumption used in this free writing prospectus with respect to the fixed-rate Mortgage Loans assumes a prepayment rate of 100% PPC. To assume 100% PPC is to assume (i) a per annum prepayment rate of 4% of the then outstanding principal balance of the mortgage loans in the first month of the life of the mortgage loans, (ii) an additional approximate 1.72727% per annum in each month thereafter through the eleventh month and (iii) a constant prepayment rate of 23% per annum beginning in the twelfth month and in each month thereafter during the life of the mortgage loans; provided, however, the prepayment rate will not exceed 85% per annum in any period for any percentage of PPC. No representation is made that the Mortgage Loans will prepay in accordance with such prepayment models or any other rate. We refer to each such prepayment model in this free writing prospectus as a “Prepayment Assumption”.

The tables entitled “Percent of Initial Certificate Principal Balance Outstanding at the Specified Percentages of the Prepayment Assumption” indicate the percentage of the initial Certificate Principal Balance of the Offered Certificates that would be outstanding after each of the dates shown at various percentages of PPC, and the corresponding weighted average lives of these certificates. The tables are based on the following assumptions (the “Modeling Assumptions”): (i) the Mortgage Pool consists of 453 assumed mortgage loans with the characteristics set forth below, (ii) distributions on the certificates are received, in cash, on the 25th day of each month, commencing in March 2007; (iii) the Mortgage Loans prepay at the percentages of PPC indicated; (iv) no defaults or delinquencies occur in the payment by mortgagors of principal and interest on the Mortgage Loans and no shortfalls due to the application of the Relief Act or similar state or local laws are incurred; (v) none of the Depositor, the Servicer, the Master Servicer or any other person purchases from the trust fund any Mortgage Loan under any obligation or option under the pooling and servicing agreement, except as indicated in footnote two in the tables; (vi) scheduled monthly payments on the Mortgage Loans are received on the first day of each month commencing in March 2007, and are computed prior to giving effect to any prepayments received in the prior month; (vii) prepayments representing payment in full of individual Mortgage Loans are received on the last day of each month commencing in February 2007, and include 30 days’ interest thereon; (viii) the scheduled monthly payment for each Mortgage Loan is calculated based on the assumed mortgage loan characteristics stated below; (ix) the certificates are purchased on, March 13, 2007; (x) Six-Month LIBOR remains constant at 5.3300% per annum and the gross mortgage rate on each ARM Loan is adjusted according to the assumed mortgage loan characteristics; (xi) One-Month LIBOR remains constant at 5.3200% per annum; (xii) the Class P Certificates have a Certificate Principal Balance equal to zero; and (xiii) rate at which the fee payable to the Servicer is calculated is assumed to be equal to 0.5000% per annum, the rate at which the fee payable to the Master Servicer is calculated is assumed to be equal to 0.0035% per annum and the rate at which the fee payable to the Credit Risk Manager is calculated is assumed to be equal to 0.0135% per annum.

*LIB6M means Six-Month LIBOR. FR means Fixed Rate.

There will be discrepancies between the characteristics of the actual Mortgage Loans and the characteristics assumed in preparing the tables entitled “Percent of Initial Certificate Principal Balance Outstanding at the Specified Percentages of the Prepayment Assumption”. Any discrepancy may have an effect upon the percentages of the initial Certificate Principal Balance outstanding, and the weighted average lives, of the Offered Certificates set forth in the tables. In addition, since the actual Mortgage Loans will have characteristics that differ from those assumed in preparing the tables and since it is not likely the level of Six-Month LIBOR or One-Month LIBOR will remain constant as assumed, the Offered Certificates may mature earlier or later than indicated by the tables. In addition, as described under “Description of the Certificates-Principal Distributions on the Offered Certificates” in this free writing prospectus, the occurrence of the Stepdown Date or a Trigger Event will have the effect of accelerating or decelerating the amortization of the Offered Certificates, affecting the weighted average lives of such certificates. Based on the foregoing assumptions, the tables indicate the weighted average lives of each class of Offered Certificates and set forth the percentages of the initial Certificate Principal Balance of such certificates that would be outstanding after each of the Distribution Dates shown, at various percentages of the Prepayment Assumption. Neither the prepayment model used in this free writing prospectus nor any other prepayment model or assumption purports to be a historical description of prepayment experience or a prediction of the anticipated rate of prepayment of any pool of mortgage loans, including the Mortgage Loans. Variations in the prepayment experience and the balance of the Mortgage Loans that prepay may increase or decrease the percentages of initial Certificate Principal Balances, and weighted average lives, shown in the following tables. These variations may occur even if the average prepayment experience of all the Mortgage Loans equals any of the specified percentages of the Prepayment Assumption.

There is no assurance that prepayments of the Mortgage Loans included in the Mortgage Pool will conform to any of the levels of the Prepayment Assumption indicated in the immediately preceding tables, or to any other level, or that the actual weighted average lives of the Class A Certificates and the Mezzanine Certificates will conform to any of the weighted average lives set forth in the immediately preceding tables. Furthermore, the information contained in the tables with respect to the weighted average lives of the Class A Certificates and the Mezzanine Certificates is not necessarily indicative of the weighted average lives that might be calculated or projected under different or varying prepayment assumptions.

The characteristics of the Mortgage Loans will differ from those assumed in preparing the immediately preceding tables. In addition, it is unlikely that any Mortgage Loan will prepay at any constant percentage until maturity or that all of the Mortgage Loans will prepay at the same rate. The timing of changes in the rate of prepayments may significantly affect the actual yield to maturity to investors, even if the average rate of principal prepayments is consistent with the expectations of investors.

Yield Sensitivity of the Mezzanine Certificates

103

Unless the aggregate Certificate Principal Balance of the Class A Certificates has been reduced to zero, principal distributions on the Mezzanine Certificates will only commence on or after the Stepdown Date and during periods in which a Trigger Event is not in effect. As a result, the weighted average lives of the Mezzanine Certificates will be longer than would otherwise be the case if distributions of principal were allocated on a pro rata basis among all of the Offered Certificates. As a result of the longer weighted average lives of the Mezzanine Certificates, the holders of such certificates have a greater risk of suffering a loss on their investments. For additional considerations relating to the yield on the Mezzanine Certificates, see “Yield Considerations” in the prospectus.

DESCRIPTION OF THE CERTIFICATES

General

The ACE Securities Corp. Home Equity Loan Trust, Series 2007-ASAP1, Asset Backed Pass-Through Certificates will consist of seventeen classes of certificates, designated as (i) the Class A-1 Certificates; (ii) the Class A-2A, Class A-2B, Class A-2C and Class A-2D Certificates (collectively, the “Class A-2 Certificates”; and together with the Class A-1 Certificates, the “Class A Certificates”); (iii) the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates (collectively, the “Mezzanine Certificates”); (iv) the Class CE Certificates (collectively, with the Mezzanine Certificates, the “Subordinate Certificates”); (v) the Class P Certificates; and (vi) the Class R Certificates (also referred to in this free writing prospectus as the “Residual Certificates”). Only the Class A Certificates and the Mezzanine Certificates (collectively, the “Offered Certificates”) are offered by this free writing prospectus.

104

Distributions on the Offered Certificates will be made on the 25th day of each month, or, if that day is not a business day, on the next succeeding business day, beginning in March 2007 to the persons in whose names such certificates are registered at the close of business on the Record Date. The “Record Date” for the Class A Certificates and the Mezzanine Certificates and any Distribution Date is the business day immediately preceding such Distribution Date, for so long as such Certificates are held in book-entry form and the last business day of the month immediately preceding the month in which the related Distribution Date occurs if such certificates are held in physical form.

The certificates represent in the aggregate the entire beneficial ownership interest in the trust fund consisting primarily of the Mortgage Pool of conventional, one- to four-family, first and second lien, fixed-rate and adjustable-rate Mortgage Loans having original terms to maturity of not greater than approximately 30 years. The Mortgage Loans have an aggregate principal balance as of the Cut-off Date of approximately $829,214,912, subject to a permitted variance of plus or minus 10%.

The Class A Certificates and the Mezzanine Certificates will have the initial Certificate Principal Balance set forth in the table appearing on the cover of this free writing prospectus. The Pass-Through Rates on the Offered Certificates will be calculated for each Distribution Date as described under “—Pass-Through Rates” below. The Class A Certificates evidence an initial aggregate undivided interest of approximately 78.10% in the trust fund, the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates evidence initial undivided interests of approximately 3.80%, approximately 3.45%, approximately 1.95%, approximately 1.80%, approximately 1.70%, approximately 1.65%, approximately 1.45%, approximately 1.40% and approximately 1.00%, respectively, in the trust fund and the Class CE Certificates evidence an initial undivided interest of approximately 3.70% in the trust fund.

Book-Entry Certificates

The Offered Certificates will be book-entry Certificates (for so long as they are registered in the name of the applicable depository or its nominee, the “Book-Entry Certificates”). Persons acquiring beneficial ownership interests in the Book-Entry Certificates (“Certificate Owners”) will hold such certificates through The Depository Trust Company (“DTC”) in the United States, or Clearstream Banking Luxembourg, formerly known as Cedelbank SA (“Clearstream”), or the Euroclear System (“Euroclear”) in Europe, if they are participants of such systems (“Clearstream Participants” or “Euroclear Participants”, respectively), or indirectly through organizations which are Clearstream or Euroclear Participants. The Book-Entry Certificates will be issued in one or more certificates which equal the aggregate Certificate Principal Balance of such Certificates and will initially be registered in the name of Cede & Co., the nominee of DTC. Clearstream and Euroclear will hold omnibus positions on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositories which in turn will hold such positions in customers’ securities accounts in the depositories, names on the books of DTC. Citibank, N.A. will act as depository for Clearstream, and JPMorgan Chase Bank, N.A. will act as depository for Euroclear (in such capacities, individually the “Relevant Depository” and collectively the “European Depositories”). Investors may hold such beneficial interests in the Book-Entry Certificates in minimum dollar denominations of $25,000 and integral multiples of $1.00 in excess thereof. Except as described below, no Certificate Owner acquiring a Book-Entry Certificate (each, a “beneficial owner”) will be entitled to receive a physical certificate representing such Certificate (a “Definitive Certificate”). Unless and until Definitive Certificates are issued, it is anticipated that the only “Certificateholder” of the Offered Certificates will be Cede & Co., as nominee of DTC. Certificate Owners will not be Certificateholders as that term is used in the pooling and servicing agreement. Certificate Owners are only permitted to exercise their rights indirectly through DTC and participants of DTC (“DTC Participants”).

105

The Certificate Owner’s ownership of a Book-Entry Certificate will be recorded on the records of the brokerage firm, bank, thrift institution or other financial intermediary (each, a “Financial Intermediary”) that maintains the Certificate Owner’s account for such purpose. In turn, the Financial Intermediary’s ownership of such Book-Entry Certificate will be recorded on the records of DTC (or of a participating firm that acts as agent for the Financial Intermediary, whose interest will in turn be recorded on the records of DTC, if the beneficial owner’s Financial Intermediary is not a DTC Participant and on the records of Clearstream or Euroclear, as appropriate).

Certificate Owners will receive all distributions of principal of and interest on the Book-Entry Certificates from the Securities Administrator through DTC and DTC Participants. While the Book-Entry Certificates are outstanding (except under the circumstances described below), under the rules, regulations and procedures creating and affecting DTC and its operations (the “Rules”), DTC is required to make book-entry transfers among DTC Participants on whose behalf it acts with respect to the Book-Entry Certificates and is required to receive and transmit distributions of principal of, and interest on, the Book-Entry Certificates. DTC Participants and indirect participants with whom Certificate Owners have accounts with respect to Book-Entry Certificates are similarly required to make book-entry transfers and receive and transmit such distributions on behalf of their respective Certificate Owners. Accordingly, although Certificate Owners will not possess certificates representing their respective interests in the Book-Entry Certificates, the Rules provide a mechanism by which Certificate Owners will receive distributions and will be able to transfer their interest.

Certificate Owners will not receive or be entitled to receive certificates representing their respective interests in the Book-Entry Certificates, except under the limited circumstances described below. Unless and until Definitive Certificates are issued, Certificate Owners who are not DTC Participants may transfer ownership of Book-Entry Certificates only through DTC Participants and indirect participants by instructing such DTC Participants and indirect participants to transfer Book-Entry Certificates, by book-entry transfer, through DTC for the account of the purchasers of such Book-Entry Certificates, which account is maintained with their respective DTC Participants. Under the Rules and in accordance with DTC’s normal procedures, transfers of ownership of Book-Entry Certificates will be executed through DTC and the accounts of the respective DTC Participants at DTC will be debited and credited. Similarly, the DTC Participants and indirect participants will make debits or credits, as the case may be, on their records on behalf of the selling and purchasing Certificate Owners.

Because of time zone differences, credits of securities received in Clearstream or Euroclear as a result of a transaction with a DTC Participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in such securities settled during such processing will be reported to the relevant Euroclear Participants or Clearstream Participants (each as defined below) on such business day. Cash received in Clearstream or Euroclear as a result of sales of securities by or through a Clearstream Participant or Euroclear Participant to a DTC Participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following the DTC settlement date. For information with respect to tax documentation procedures relating to the Certificates, see “Global Clearance and Settlement and Documentation Procedures-Certain U.S. Federal Income Tax Documentation Requirements” in Annex I hereto.

106

Transfers between DTC Participants will occur in accordance with DTC rules. Transfers between Clearstream Participants and Euroclear Participants will occur in accordance with their respective rules and operating procedures.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and, directly or indirectly through Clearstream Participants or Euroclear Participants, on the other, will be effected in DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the Relevant Depository; however, such cross market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system, if the transaction meets its settlement requirements, will deliver instructions to the Relevant Depository to take action to effect final settlement on its behalf by delivering or receiving securities in DTC, and making or receiving payment in accordance with normal procedures for same day funds settlement applicable to DTC. Clearstream Participants and Euroclear Participants may not deliver instructions directly to the European Depositories.

DTC which is a New York-chartered limited purpose trust company, performs services for its DTC Participants, some of which (and/or their representatives) own DTC. In accordance with its normal procedures, DTC is expected to record the positions held by each DTC Participant in the Book-Entry Certificates, whether held for its own account or as a nominee for another person. In general, beneficial ownership of Book-Entry Certificates will be subject to the rules of DTC, as in effect from time to time.

Clearstream, 67 Bd Grande-Duchesse Charlotte, L-1331 Luxembourg, was incorporated in 1970 as a limited company under Luxembourg law. Clearstream is owned by banks, securities dealers and financial institutions, and currently has about 100 shareholders, including U.S. financial institutions or their subsidiaries. No single entity may own more than five percent of Clearstream’s stock.

Clearstream is registered as a bank in Luxembourg, and as such is subject to regulation by the Institute Monetaire Luxembourgeois, the Luxembourg Monetary Authority, which supervises Luxembourg banks.

Clearstream holds securities for its customers and facilitates the clearance and settlement of securities transactions by electronic book-entry transfers between their accounts. Clearstream provides various services, including safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream also deals with domestic securities markets in several countries through established depository and custodial relationships. Clearstream has established an electronic bridge with the Euroclear Operator (as defined below) in Brussels to facilitate settlement of trades between systems. Clearstream currently accepts over 70,000 securities issues on its books.

Clearstream’s customers are world-wide financial institutions including underwriters, securities brokers and dealers, banks, trust companies and clearing corporations. Clearstream’s United States customers are limited to securities brokers and dealers and banks. Currently, Clearstream has approximately 3,000 customers located in over 60 countries, including all major European countries, Canada, and the United States. Indirect access to Clearstream is available to other institutions which clear through or maintain a custodial relationship with an account holder of Clearstream.

107

Euroclear was created in 1968 to hold securities for its participants and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Transactions may be settled in any of 29 currencies, including United States dollars. Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several countries generally similar to the arrangements for cross-market transfers with DTC described above. Euroclear is operated by the Euroclear Bank S.A/N.V. (the “Euroclear Operator”), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants, and has no record of or relationship with persons holding through Euroclear Participants.

Distributions on the Book-Entry Certificates will be made on each Distribution Date by the Securities Administrator to Cede & Co. DTC will be responsible for crediting the amount of such payments to the accounts of the applicable DTC Participants in accordance with DTC’s normal procedures. Each DTC Participant will be responsible for disbursing such payments to the Certificate Owners of the Book-Entry Certificates that it represents and to each Financial Intermediary for which it acts as agent. Each such Financial Intermediary will be responsible for disbursing funds to the Certificate Owners of the Book-Entry Certificates that it represents.

Under a book-entry format, Certificate Owners of the Book-Entry Certificates may experience some delay in their receipt of payments, since such payments will be forwarded by the Securities Administrator to Cede & Co. Distributions with respect to Certificates held through Clearstream or Euroclear will be credited to the cash accounts of Clearstream Participants or Euroclear Participants in accordance with the relevant system’s rules and procedures, to the extent received by the Relevant Depository. Such distributions will be subject to tax reporting in accordance with relevant United States tax laws and regulations. See “Material Federal Income Tax Considerations REMICS-Taxation of Certain Foreign Investors” in the prospectus. Because DTC can only act on behalf of Financial Intermediaries, the ability of a Certificate Owner to pledge Book-Entry Certificates to persons or entities that do not participate in the Depository system, or otherwise take actions in respect of such Book-Entry Certificates, may be limited due to the lack of physical certificates for such Book-Entry Certificates. In addition, issuance of the Book-Entry Certificates in book-entry form may reduce the liquidity of such Certificates in the secondary market since certain potential investors may be unwilling to purchase Certificates for which they cannot obtain physical certificates.

DTC has advised the Securities Administrator that, unless and until Definitive Certificates are issued, DTC will take any action permitted to be taken by the holders of the Book-Entry Certificates under the pooling and servicing agreement only at the direction of one or more Financial Intermediaries to whose DTC accounts the Book-Entry Certificates are credited, to the extent that such actions are taken on behalf of Financial Intermediaries whose holdings include such Book-Entry Certificates. Clearstream or the Euroclear Operator, as the case may be, will take any other action permitted to be taken by a Certificateholder under the pooling and servicing agreement on behalf of a Clearstream Participant or Euroclear Participant only in accordance with its relevant rules and procedures and subject to the ability of the Relevant Depository to effect such actions on its behalf through DTC. DTC may take actions, at the direction of the related DTC Participants, with respect to some Book-Entry Certificates which conflict with actions taken with respect to other Book-Entry Certificates.

108

Definitive Certificates will be issued to Certificate Owners of the Book-Entry Certificates, or their nominees, rather than to DTC or its nominee, only if (a) DTC or the Depositor advises the Securities Administrator in writing that DTC is no longer willing, qualified or able to discharge properly its responsibilities as nominee and depository with respect to the Book-Entry Certificates and the Depositor is unable to locate a qualified successor, (b) the Depositor, at its sole option, with the consent of the Securities Administrator, elects to terminate a book-entry system through DTC or (c) after the occurrence of an Event of Default (as defined in the pooling and servicing agreement), Certificate Owners having percentage interests aggregating not less than 51% of the Book-Entry Certificates advise the Securities Administrator and DTC through the Financial Intermediaries and the DTC Participants in writing that the continuation of a book-entry system through DTC (or a successor thereto) is no longer in the best interests of Certificate Owners.

Upon the occurrence of any of the events described in the immediately preceding paragraph, the Securities Administrator will be required to cause DTC to notify all Certificate Owners of the occurrence of such event and the availability through DTC of Definitive Certificates. Upon surrender by DTC of the global certificate or certificates representing the Book-Entry Certificates and instructions for re-registration, the Securities Administrator will issue Definitive Certificates, and thereafter the Securities Administrator will recognize the holders of such Definitive Certificates as Certificateholders under the pooling and servicing agreement.

In the event any Definitive Certificates are issued, surrender of such Definitive Certificates shall occur at the office designated from time to time for such purposes by the certificate registrar. As of the Closing Date, the certificate registrar designates its offices located at Sixth Street and Marquette Avenue, Minneapolis, Minnesota 55479 for this purpose.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of Book-Entry Certificates among DTC Participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be discontinued at any time.

None of the Depositor, the Servicer, the Master Servicer, the Securities Administrator or the Trustee will have any responsibility for any aspect of the records relating to or payments made on account of beneficial ownership interests of the Book-Entry Certificates held by Cede & Co., as nominee for DTC, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or any transfers thereof.

The Trustee will appoint the Securities Administrator to receive and distribute funds in respect of the Cap Agreements on behalf of the trust.

Under the Cap Agreement relating to the Class A-1 Certificates and Mezzanine Certificates (the “Group I Cap Agreement”) on or before each Distribution Date commencing with the Distribution Date in March 2007 and terminating immediately following the Distribution Date in August 2007, the Cap Provider will be obligated to make a payment for that Distribution Date equal to the product of (x) the excess, if any, of (i) One-Month LIBOR as determined pursuant to the Group I Cap Agreement for the related calculation period (as defined in the Group I Cap Agreement) over (ii) the strike rate for such Distribution Date set forth in the Group I Cap Agreement, (y) the Group I Cap Agreement Notional Amount (as defined below) for that Distribution Date, and (z) a fraction, the numerator of which is equal to the actual number of days in the related calculation period and the denominator of which is 360.

If, on any Distribution Date, the payments received by the Securities Administrator under the Cap Agreements exceed the amount of the Net WAC Rate Carryover Amounts payable to the Class A Certificates and Mezzanine Certificates for such Distribution Date, such excess will be distributed to the Class CE Certificates.

The obligations of the Cap Provider to pay specified amounts due under each Cap Agreement (other than Cap Agreement Termination Payments (as defined below)) will generally be subject to the following conditions precedent: (1) no Cap Agreement Event of Default or event that with the giving of notice or lapse of time or both would become a Cap Agreement Event of Default will have occurred and be continuing with respect to the related Cap Agreement and (2) no “early termination date” (as defined in the related Cap Agreement) has occurred or been effectively designated with respect to the related Cap Agreement.

Events of default under each Cap Agreement (each a “Cap Agreement Event of Default”) include the following:

Upon the occurrence of a Cap Agreement Event of Default, the non-defaulting party will have the right to designate an early termination date (an “Early Termination Date”). Upon the occurrence of a Cap Agreement Termination Event or a Cap Agreement Additional Termination Event, an Early Termination Date may be designated by one of the parties as specified in the Cap Agreement, and will occur only upon notice and, in some circumstances, after any affected party has used reasonable efforts to transfer its rights and obligations under the Cap Agreement to a related entity within a specified period after notice has been given of the Cap Agreement Termination Event, and, in the case of downgrade below the second ratings threshold, only if a firm offer from a replacement cap provider remains capable of acceptance by the offeree, all as set forth in the Cap Agreement. The occurrence of an Early Termination Date under the related Cap Agreement will constitute a “Cap Agreement Early Termination.”

Upon a Cap Agreement Early Termination, the Cap Provider may be liable to make a termination payment (the “Cap Agreement Termination Payment”) to the Securities Administrator (regardless, if applicable, of which of the parties has caused the termination). The Cap Agreement Termination Payment will be based on the value of related Cap Agreement computed in accordance with the procedures set forth in such Cap Agreement.

The Securities Administrator will apply any Cap Agreement Termination Payment received from the original Cap Provider in connection with such Cap Agreement Early Termination to the upfront payment required to appoint the successor cap provider. If the Securities Administrator is unable to appoint a successor cap provider within 30 days of the Cap Agreement Early Termination, then the Securities Administrator will deposit any Cap Termination Payment received from the original Cap Provider into a separate, non-interest bearing reserve account and will, on each subsequent Distribution Date, withdraw from the amount then remaining on deposit in such reserve account an amount equal to the payment, if any, that would have been paid to the Securities Administrator by the original Cap Provider calculated in accordance with the terms of the original Cap Agreement, and distribute such amount in accordance with the terms of the pooling and servicing agreement.

Upon a Cap Agreement Early Termination in connection with the Optional Termination relating to the Mortgage Loans, if the Securities Administrator receives a Cap Agreement Termination Payment from the Cap Provider, such Cap Agreement Termination Payment generally will not be available to holders of the Certificates; rather, the Securities Administrator will distribute such Cap Agreement Termination Payment in accordance with the terms of the pooling and servicing agreement.

The significance percentage of the Cap Agreements and the Interest Rate Swap Agreement, individually and in combination, as calculated in accordance with Item 1115 of Regulation AB, is less than 10%. The Cap Agreements and the Interest Rate Swap Agreement will provide that the Cap Provider and Swap Provider may be replaced in certain circumstances, including if the significance percentage of the Cap Agreements and the Interest Rate Swap Agreement, individually or in combination, is equal to or greater than 10%.

The Cap Agreements will be governed by and construed in accordance with the laws of the State of New York. The obligations of the Cap Provider are limited to those specifically set forth in the Cap Agreements.

The respective obligations of the Swap Provider and the Supplemental Interest Trust to pay specified amounts due under the Interest Rate Swap Agreement (other than Swap Termination Payments (as defined below)) will be subject to the following conditions precedent: (1) no Swap Event of Default or event that with the giving of notice or lapse of time or both would become a Swap Event of Default, shall have occurred and be continuing with respect to the Interest Rate Swap Agreement and (2) no “Early Termination Date” (as defined in the Interest Rate Swap Agreement) has occurred or been effectively designated with respect to the Interest Rate Swap Agreement.

Events of default under the Interest Rate Swap Agreement (each a “Swap Event of Default”) include the following:

failure to make a payment as required under the terms of the Interest Rate Swap Agreement,

failure by the Swap Provider to comply with or perform certain agreements or obligations as required under the terms of the Interest Rate Swap Agreement,

failure to comply with or perform certain agreements or obligations in connection with any credit support document as required under the terms of the Interest Rate Swap Agreement,

certain representations by the Swap Provider or its credit support provider prove to have been incorrect or misleading in any material respect,

repudiation or certain defaults by the Swap Provider or any credit support provider in respect of any derivative or similar transactions entered into between the Supplemental Interest Trust Trustee and the Swap Provider and specified for this purpose in the Interest Rate Swap Agreement,

126

cross-default by the Swap Provider or any credit support provider relating generally to its obligations in respect of borrowed money in excess of a threshold specified in the Interest Rate Swap Agreement,

certain insolvency or bankruptcy events, and

a merger by a party to the Interest Rate Swap Agreement without an assumption of such party’s obligations under the Interest Rate Swap Agreement,

each as further described in the Interest Rate Swap Agreement.

Termination events under the Interest Rate Swap Agreement (each a “Swap Termination Event”) include the following:

illegality (which generally relates to changes in law causing it to become unlawful for either party to perform its obligations under the Interest Rate Swap Agreement),

tax event (which generally relates to the application of certain withholding taxes to amounts payable under the Interest Rate Swap Agreement, as a result of a change in tax law or certain similar events), and

tax event upon merger (which generally relates to the application of certain withholding taxes to amounts payable under the Interest Rate Swap Agreement as a result of a merger or similar transaction),

each as further described in the Interest Rate Swap Agreement.

Additional termination events under the Interest Rate Swap Agreement (each a “Swap Additional Termination Event”), include the following:

failure of the Swap Provider to maintain certain credit ratings or otherwise comply with the downgrade provisions of the Interest Rate Swap Agreement (including certain collateral posting requirements), in each case in certain circumstances as specified in the Interest Rate Swap Agreement,

failure of the Swap Provider to comply with the Regulation AB provisions of the Interest Rate Swap Agreement (including, if applicable, the provisions of any additional agreement incorporated by reference into the Interest Rate Swap Agreement),

occurrence of an optional termination of the securitization pursuant to the terms of the Pooling and Servicing Agreement, and

amendment of the Pooling and Servicing Agreement in a manner contrary to the requirements of the Interest Rate Swap Agreement,

each as further described in the Interest Rate Swap Agreement.

If the Swap Provider’s credit ratings are withdrawn or reduced below certain ratings thresholds specified in the Interest Rate Swap Agreement, the Swap Provider may be required, at its own expense and in accordance with the requirements of the Interest Rate Swap Agreement, to do one or more of the following: (1) obtain a substitute swap provider, or (2) establish any other arrangement as may be specified for such purpose in the Interest Rate Swap Agreement.

127

Upon the occurrence of a Swap Event of Default, the non-defaulting party will have the right to designate an early termination date (an “Early Termination Date”). Upon the occurrence of a Swap Termination Event or a Swap Additional Termination Event, an Early Termination Date may be designated by one of the parties as specified in the Interest Rate Swap Agreement, and will occur only upon notice (including, in some circumstances, notice to the rating agencies) and, in some circumstances, after any affected party has used reasonable efforts to transfer its rights and obligations under the Interest Rate Swap Agreement to a related entity within a specified period after notice has been given of the Swap Termination Event, and, in the case of downgrade below the second ratings threshold, only if a firm offer remains capable of acceptance by the offeree, all as set forth in the Interest Rate Swap Agreement. The occurrence of an Early Termination Date under the Interest Rate Swap Agreement will constitute a “Swap Early Termination.”

Upon a Swap Early Termination, the Securities Administrator (on behalf of the Supplemental Interest Trust) or the Swap Provider may be liable to make a swap termination payment (the “Swap Termination Payment”) to the other, regardless, if applicable, of which of the parties has caused the termination. The Swap Termination Payment will be based on the value of the Interest Rate Swap Agreement computed in accordance with the procedures set forth in the Interest Rate Swap Agreement. In the event that the Securities Administrator is required to make a Swap Termination Payment to the Swap Provider, the trust will be required to make a payment to the Securities Administrator in the same amount (to the extent such Swap Termination Payment has not been paid by the Securities Administrator from any upfront payment received pursuant to any replacement interest rate swap agreement that may be entered into by the Supplemental Interest Trust Trustee). In the case of a Swap Termination Payment not triggered by a Swap Provider Trigger Event (as defined in this free writing prospectus), the trust will be required to make such payment on the related distribution date, and on any subsequent Distribution Dates until paid in full, prior to distributions to certificateholders. In the case of a Swap Termination Payment triggered by a Swap Provider Trigger Event, the trust’s obligation to make such payment generally will be subordinated to distributions to the holders of the Offered Certificates to the extent described in the pooling and servicing agreement.

Upon a Swap Early Termination other than in connection with the optional termination with respect to the Mortgage Loans, the Securities Administrator shall, at the direction of the depositor, appoint a successor swap provider. If the Securities Administrator receives a Swap Termination Payment from the Swap Provider in connection with such Swap Early Termination, the Securities Administrator will apply such Swap Termination Payment to any upfront payment required to appoint the successor swap provider. If the Securities Administrator is required to pay a Swap Termination Payment to the Swap Provider in connection with such Swap Early Termination, the Securities Administrator will apply any upfront payment received from the successor swap provider to pay such Swap Termination Payment. If the Securities Administrator is unable to appoint a successor swap provider within 30 days of the Swap Early Termination, then the Securities Administrator will deposit any Swap Termination Payment received from the original Swap Provider into a separate, non-interest bearing reserve account and will, on each subsequent Distribution Date, withdraw from the amount then remaining on deposit in such reserve account an amount equal to the Net Swap Payment, if any, that would have been paid to the Securities Administrator by the original Swap Provider calculated in accordance with the terms of the original Interest Rate Swap Agreement, and distribute such amount in accordance with the terms of the pooling and servicing agreement.

Upon a Swap Early Termination in connection with the optional termination of the trust, if the Securities Administrator is required to make a Swap Termination Payment to the Swap Provider, the party exercising such optional termination with respect to the Mortgage Loans will be required to include in its payment an amount equal to such Swap Termination Payment, as described in this free writing prospectus. If the Securities Administrator receives a Swap Termination Payment from the Swap Provider in connection with such Swap Early Termination, such Swap Termination Payment generally will not be available to certificateholders; rather, the Securities Administrator will distribute such Swap Termination Payment in accordance with the terms of the pooling and servicing agreement.

128

A “Swap Provider Trigger Event” will mean: (i) a Swap Event of Default under the Interest Rate Swap Agreement with respect to which the Swap Provider is a Defaulting Party (as defined in the Interest Rate Swap Agreement), (ii) a Swap Termination Event under the Interest Rate Swap Agreement with respect to which the Swap Provider is the sole Affected Party (as defined in the Interest Rate Swap Agreement) or (iii) a Swap Additional Termination Event under the Interest Rate Swap Agreement with respect to which the Swap Provider is the sole Affected Party.

On each Distribution Date commencing on the Distribution Date occurring in September 2007 and terminating immediately following the Distribution Date in February 2012 to the extent required, following the distribution of the Net Monthly Excess Cashflow and withdrawals from the Reserve Fund, as described in “—Overcollateralization Provisions” in this free writing prospectus, any Net Swap Payment payable to the Securities Administrator on behalf of the Supplemental Interest Trust by the Swap Provider will be distributed on the related Distribution Date in the following order of priority:

first, concurrently, to each class of Class A Certificates, the related Senior Interest Distribution Amount remaining undistributed after the distributions of the Group I Interest Remittance Amount and Group II Interest Remittance Amount, on a pro rata basis based on such respective remaining Senior Interest Distribution Amounts;

second, sequentially, to the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in that order, the related Interest Distribution Amount and Interest Carry Forward Amount, to the extent remaining undistributed after the distributions of the Group I Interest Remittance Amount and Group II Interest Remittance Amount and the Net Monthly Excess Cashflow;

third, to the holders of the class or classes of Certificates then entitled to receive distributions in respect of principal, in an amount necessary to maintain or restore the Required Overcollateralization Amount after taking into account distributions made pursuant to clause first under “—Overcollateralization Provisions;”

fourth, sequentially to the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in that order, in each case up to the related Allocated Realized Loss Amount related to such Certificates for such Distribution Date remaining undistributed after distribution of the Net Monthly Excess Cashflow;

fifth, concurrently, to each class of Class A Certificates, the related Net WAC Rate Carryover Amount, to the extent remaining undistributed after distributions of amounts received by the Securities Administrator in respect of the Net Monthly Excess Cashflow on deposit in the Reserve Fund, on a pro rata basis based on such respective Net WAC Rate Carryover Amounts remaining;

129

sixth, sequentially, to the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in that order, the related Net WAC Rate Carryover Amount, to the extent remaining undistributed after distributions of Net Monthly Excess Cashflow on deposit in the Reserve Fund;

seventh, to the Swap Provider, an amount equal to any Swap Termination Payment owed to the Swap Provider due to a Swap Provider Trigger Event pursuant to the Interest Rate Swap Agreement; and

eighth, to the Class CE Certificates, any remaining amounts.

Amounts payable by the trust to the Securities Administrator in respect of Net Swap Payments and Swap Termination Payments other than Swap Termination Payments resulting from a Swap Provider Trigger Event (and to the extent not paid by the Securities Administrator from any upfront payment received pursuant to any replacement interest rate swap agreement that may be entered into by the Supplemental Interest Trust Trustee) will be deducted from related available funds before distributions to the holders of the Offered Certificates. On or before each Distribution Date, such amounts will be distributed by the trust to the Securities Administrator, and paid by the Securities Administrator to the Swap Provider as follows:

(i) first, to make any Net Swap Payment owed to the Swap Provider pursuant to the Interest Rate Swap Agreement for such Distribution Date, and

(ii) second, to make any Swap Termination Payment not due to a Swap Provider Trigger Event owed to the Swap Provider pursuant to the Interest Rate Swap Agreement (to the extent not paid by the Securities Administrator from any upfront payment received pursuant to any replacement interest rate swap agreement that may be entered into by the Securities Administrator).

The Interest Rate Swap Agreement will be governed by and construed in accordance with the laws of the State of New York. The obligations of the Swap Provider are limited to those specifically set forth in the Interest Rate Swap Agreement, as applicable.

Interest Distributions on the Offered Certificates

Holders of the Offered Certificates will be entitled to receive on each Distribution Date, interest distributions in an aggregate amount equal to interest accrued during the related Interest Accrual Period on the Certificate Principal Balances thereof at the then-applicable Pass-Through Rates thereon, in the priorities set forth below.

(A) On each Distribution Date, the Group I Interest Remittance Amount will be distributed in the following order of priority:

first, commencing on the Distribution Date occurring in September 2007, to the Supplemental Interest Trust, an amount equal to (x) the Group I Allocation Percentage of (i) any Net Swap Payment owed to the Swap Provider and (ii) any Swap Termination Payment owed to the Swap Provider not due to a Swap Provider Trigger Event and (y) any Swap Payment and Swap Termination Payment not paid pursuant to clause (x) in (B) “first” below;

third, concurrently, to the holders of the Class A-2A, Class A-2B, Class A-2C and Class A-2D Certificates, the Senior Interest Distribution Amount allocable to each such class, to the extent remaining unpaid after distribution of the Group II Interest Remittance Amount as set forth in clause (B) below, on a pro rata basis, based on the entitlement of each such class.

130

(B) On each Distribution Date, the Group II Interest Remittance Amount will be distributed in the following order of priority:

first, commencing on the Distribution Date occurring in September 2007, to the Supplemental Interest Trust, an amount equal to (x) the Group II Allocation Percentage of (i) any Net Swap Payment owed to the Swap Provider and (ii) any Swap Termination Payment owed to the Swap Provider not due to a Swap Provider Trigger Event and (y) any Swap Payment and Swap Termination Payment not paid pursuant to clause (x) in (A) “first” above;

second, concurrently, to the holders of the Class A-2A, Class A-2B, Class A-2C and Class A-2D Certificates, the Senior Interest Distribution Amount allocable to each such class, on a pro rata basis, based on the entitlement of each such class; and

(C) On each Distribution Date, following the deposit of the Net Swap Payment and any Swap Termination Payment into the Supplemental Interest Trust as described in clauses (A) and (B) above and the distributions of interest to the holders of the Class A Certificates as described in clauses (A) and (B) above, any Group I Interest Remittance Amount and Group II Interest Remittance Amount remaining will be distributed sequentially, to the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in that order, to the extent of the Interest Distribution Amount allocable to each such class.

On any Distribution Date, any shortfalls resulting from the application of the Relief Act or any similar state or local law and any Prepayment Interest Shortfalls to the extent not covered by Compensating Interest paid by the Servicer or the Master Servicer will be allocated first, to Net Monthly Excess Cashflow and payments received under the Interest Rate Swap Agreement according to the priorities set forth under “Description of the Certificates—The Interest Rate Swap Agreement” and “—Overcollateralization Provisions” in this free writing prospectus, second, to the Class M-9 Certificates, third, to the Class M-8 Certificates, fourth, to the Class M-7 Certificates, fifth, to the Class M-6 Certificates, sixth, to the Class M-5 Certificates, seventh, to the Class M-4 Certificates, eighth, to the Class M-3 Certificates, ninth, to the Class M-2 Certificates, tenth, to the Class M-1 Certificates and eleventh, to the Class A Certificates, on a pro rata basis, based on their respective Senior Interest Distribution Amounts before such reduction. The holders of the Offered Certificates will be entitled to reimbursement for any of these interest shortfalls, subject to available funds, in the priorities described under “—Overcollateralization Provisions” in this free writing prospectus.

With respect to any Distribution Date, to the extent that the aggregate Interest Distribution Amount exceeds the Interest Remittance Amount, a shortfall in interest distributions on one or more classes of Offered Certificates will result and payments of Interest Carry Forward Amounts to such classes of Offered Certificates will be made. The Interest Carry Forward Amount with respect to the Class A Certificates, if any, is distributed as part of the Senior Interest Distribution Amount on each Distribution Date. The Interest Carry Forward Amount with respect to the Mezzanine Certificates, if any, may be carried forward to succeeding Distribution Dates and, subject to available funds, will be distributed in the manner set forth in “—Overcollateralization Provisions” and “—The Interest Rate Swap Agreement” in this free writing prospectus.

131

Except as otherwise described in this free writing prospectus, on any Distribution Date, distributions of the Interest Distribution Amount for a class of certificates will be made in respect of that class of certificates, to the extent provided in this free writing prospectus, on a pari passu basis, based on the Certificate Principal Balance of the certificates of each class.

Calculation of One-Month LIBOR

As used in this section, “business day” means a day on which banks are open for dealing in foreign currency and exchange in London and New York; “Telerate Page 3750” means the display page currently so designated on the Dow Jones Telerate Capital Markets Report (or such other page as may replace that page on that service for the purpose of displaying comparable rates or prices); “Reference Banks” means leading banks selected by the Securities Administrator and engaged in transactions in Eurodollar deposits in the international Eurocurrency market (i) with an established place of business in London, (ii) which have been designated as such by the Securities Administrator and (iii) not controlling, controlled by, or under common control with, the Depositor or the Securities Administrator, and “Reserve Interest Rate” shall be the rate per annum that the Securities Administrator determines to be either (i) the arithmetic mean (rounded upwards if necessary to the nearest whole multiple of 0.0625%) of the one-month U.S. dollar lending rates which New York City banks selected by the Securities Administrator are quoting on the relevant Interest Determination Date to the principal London offices of leading banks in the London interbank market or (ii) in the event that the Securities Administrator can determine no such arithmetic mean, the lowest one-month U.S. dollar lending rate which New York City banks selected by the Securities Administrator are quoting on such Interest Determination Date to leading European banks.

The establishment of One-Month LIBOR on each Interest Determination Date by the Securities Administrator and the Securities Administrator’s calculation of the rate of interest applicable to the Offered Certificates for the related Interest Accrual Period shall (in the absence of manifest error) be final and binding.

132

fifth, to the holders of the Class M-5 Certificates, the lesser of (x) the excess of (i) the Principal Distribution Amount over (ii) the sum of the amounts distributed to the Supplemental Interest Trust and to the holders of the Class A Certificates under (D) and (E) above, to the holders of the Class M-1 Certificates under clause first above, to the holders of the Class M-2 Certificates under clause second above, to the holders of the Class M-3 Certificates under clause third above and to the holders of the Class M-4 Certificates under clause fourth above and (y) the Class M-5 Principal Distribution Amount, until the Certificate Principal Balance of the Class M-5 Certificates has been reduced to zero;

135

The allocation of distributions in respect of principal to the Class A Certificates on each Distribution Date (a) prior to the Stepdown Date or (b) on which a Trigger Event has occurred, will have the effect of accelerating the amortization of the Class A Certificates while, in the absence of Realized Losses, increasing the respective percentage interest in the principal balance of the Mortgage Loans evidenced by the Mezzanine Certificates. Increasing the respective percentage interest in the trust fund of the Mezzanine Certificates relative to that of the Class A Certificates is intended to preserve the availability of the subordination provided by the Mezzanine Certificates.

Notwithstanding the priority of distributions described in this section with respect to the Class A-2A, Class A-2B, Class A-2C and Class A-2D Certificates, on any Distribution Date which occurs after the Certificate Principal Balances of the Mezzanine Certificates and Class CE Certificates have been reduced to zero distributions in respect of principal to the Class A-2A, Class A-2B, Class A-2C and Class A-2D Certificates will be made on a pro rata basis, based on the Certificate Principal Balance of each such class, until the Certificate Principal Balance of each such class has been reduced to zero.

Credit Enhancement

The credit enhancement provided for the benefit of the holders of the Class A Certificates consists of subordination, as described in this section and overcollateralization, as described under “—Overcollateralization Provisions” in this free writing prospectus.

The rights of the holders of the Subordinate Certificates to receive distributions will be subordinated, to the extent described in this section, to the rights of the holders of the Class A Certificates. This subordination is intended to enhance the likelihood of regular receipt by the holders of the Class A Certificates of the full amount of their scheduled monthly payments of interest and principal and to afford holders of the Class A Certificates protection against Realized Losses.

138

The protection afforded to the holders of the Class A Certificates by means of the subordination of the Subordinate Certificates will be accomplished by (i) the preferential right of the holders of the Class A Certificates to receive on any Distribution Date, prior to distribution on the Subordinate Certificates, distributions in respect of interest and principal, subject to available funds and (ii) if necessary, the right of the holders of the Class A Certificates to receive future distributions of amounts that would otherwise be payable to the holders of the Subordinate Certificates.

Overcollateralization Provisions

The weighted average Mortgage Rate for the Mortgage Loans, less the Administration Fee Rate and the amount, expressed as a per annum rate, of any Net Swap Payments payable to the Swap Provider and any Swap Termination Payments payable to the Swap Provider not due to a Swap Provider Trigger Event, is expected to be higher than the weighted average of the Pass-Through Rates on the Offered Certificates, thus generating excess interest collections which, in the absence of Realized Losses, will not be necessary to fund interest distributions on the Offered Certificates. Additional excess interest will be generated by the portion of the Mortgage Pool represented by the Overcollateralization Amount. The pooling and servicing agreement requires that, on each Distribution Date, the Net Monthly Excess Cashflow, if any, be applied on the related Distribution Date as an accelerated payment of principal on the class or classes of Offered Certificates then entitled to receive distributions in respect of principal, but only to the limited extent described in this section.

With respect to any Distribution Date, any Net Monthly Excess Cashflow (or, in the case of clause first below, the Net Monthly Excess Cashflow exclusive of any Overcollateralization Reduction Amount) shall be paid as follows:

first, to the holders of the class or classes of certificates then entitled to receive distributions in respect of principal, in an amount equal to the Overcollateralization Increase Amount for such Distribution Date, owed to such holders to be paid as part of the Principal Distribution Amount;

139

second, sequentially, to the holders of the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in that order, in an amount equal to the Interest Carry Forward Amount allocable to each such class;

third, sequentially to the holders of the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in that order, in an amount equal to the Allocated Realized Loss Amount allocable to each such class;

fourth, concurrently to the holders of the Class A Certificates, in an amount equal to such certificates’ allocated share of any Prepayment Interest Shortfalls on the related Mortgage Loans to the extent not covered by Compensating Interest paid by the Master Servicer or the Servicer and any shortfalls resulting from the application of the Relief Act or similar state or local law or the bankruptcy code with respect to the related Mortgage Loans;

fifth, sequentially to the holders of the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in that order, in an amount equal to each such certificates’ allocated share of any Prepayment Interest Shortfalls on the Mortgage Loans to the extent not covered by Compensating Interest paid by the Master Servicer or the Servicer and any shortfalls resulting from the application of the Relief Act or similar state or local law or the bankruptcy code with respect to the Mortgage Loans;

sixth, to the reserve fund (the “Reserve Fund”) established in accordance with the terms of the pooling and servicing agreement, the amount by which the Net WAC Rate Carryover Amounts, if any, with respect to the Class A Certificates and Mezzanine Certificates exceeds the sum of any amounts received by the Securities Administrator with respect to the Cap Agreements since the prior Distribution Date and any amounts in the Reserve Fund that were not distributed on prior Distribution Dates;

seventh, commencing on the Distribution Date occurring in September 2007, to the Supplemental Interest Trust, an amount equal to any Swap Termination Payment owed to the Swap Provider, due to a Swap Provider Trigger Event pursuant to the Interest Rate Swap Agreement;

eighth, to the holders of the Class P Certificates and Class CE Certificates as provided in the Pooling and Servicing Agreement; provided, however, that the Certificate Principal Balance of the Class P Certificates will not be reduced until the Distribution Date following the expiration of the latest prepayment charge term with respect to the Mortgage Loans; and

ninth, to the holders of the Residual Certificates, any remaining amounts.

On each Distribution Date, the Securities Administrator will deposit all amounts received with respect to the Cap Agreements into the Reserve Fund. On each Distribution Date, after making the distributions required under “Interest Distributions on the Offered Certificates”, “Principal Distributions on the Offered Certificates” and after the distribution of the Net Monthly Excess Cashflow as described above, the Securities Administrator will withdraw from the Reserve Fund the amounts on deposit therein (which shall include any payments received under the Cap Agreements) and distribute such amounts to the Class A Certificates and the Mezzanine Certificates in respect of any Net WAC Rate Carryover Amounts due to each such class in the following manner and order of priority:

140

(A) any amounts received by the Securities Administrator on account of the Group I Cap Agreement will be distributed to the holders of the Class A-1 Certificates in respect of the related Net WAC Rate Carryover Amount for such Distribution Date;

(B) any amounts received by the Securities Administrator on account of the Group II Cap Agreement will be distributed concurrently to the holders of the Class A-2A, Class A-2B, Class A-2C and Class A-2D Certificates in respect of the related Net WAC Rate Carryover Amount for such Distribution Date, on a pro rata basis, based on the entitlement of each such class;

(C) any remaining amounts received by the Securities Administrator on account of the Cap Agreements will be distributed sequentially to the holders of the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in that order, in respect of the related Net WAC Rate Carryover Amount for each such class for such Distribution Date;

(D) any amounts deposited in the Reserve Fund from the Net Monthly Excess Cashflow will be distributed:

first, concurrently, (i) to the holders of the Class A-1 Certificates, the related Net WAC Rate Carryover Amount for such Distribution Date to the extent not paid pursuant to clause (A) above, and (ii) to the holders of the Class A-2A, Class A-2B, Class A-2C and Class A-2D Certificates, the related Net WAC Rate Carryover Amount for such Distribution Date to the extent not paid pursuant to clause (B) above, on a pro rata basis, based on the entitlement of each such class; and

second, sequentially, to the holders of the Class M-1, Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8 and Class M-9 Certificates, in that order, in respect of the related Net WAC Rate Carryover Amount for each such class for such Distribution Date to the extent not paid pursuant to clause (D) above.

As of the Closing Date, the aggregate principal balance of the Mortgage Loans as of the Cut-off Date will exceed the sum of the aggregate Certificate Principal Balances of the Offered Certificates and the Class P Certificates by an amount equal to approximately $30,679,812 (subject to a permitted variance of plus or minus 10%), which is equal to the initial Certificate Principal Balance of the Class CE Certificates. This amount represents approximately 3.70% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date, which is the initial amount of overcollateralization required to be provided by the Mortgage Pool under the pooling and servicing agreement. Under the pooling and servicing agreement, the Overcollateralization Amount is required to be maintained at the “Required Overcollateralization Amount.” In the event that Realized Losses are incurred on the Mortgage Loans, such Realized Losses may result in an overcollateralization deficiency since the Realized Losses will reduce the principal balance of the Mortgage Loans without a corresponding reduction to the aggregate Certificate Principal Balances of the Offered Certificates. In the event of an overcollateralization deficiency, the pooling and servicing agreement requires the payment from Net Monthly Excess Cashflow and any Net Swap Payments received from the Swap Provider in respect of the Interest Rate Swap Agreement, subject to available funds, of an amount equal to the overcollateralization deficiency, which shall constitute a principal distribution on the Offered Certificates in reduction of the Certificate Principal Balances of the Offered Certificates. These payments have the effect of accelerating the amortization of the Offered Certificates relative to the amortization of the Mortgage Loans, and of increasing the Overcollateralization Amount.

141

On and after the Stepdown Date and provided that a Trigger Event is not in effect, the Required Overcollateralization Amount may be permitted to decrease (“step down”), to a level equal to a percentage ranging from 6.40% to 8.40% of the then current aggregate outstanding principal balance of the Mortgage Loans as of the last day of the related Due Period, subject to a floor equal to the product (i) 0.50% and (ii) the aggregate principal balance of the Mortgage Loans as of the Cut-off Date. In the event that the Required Overcollateralization Amount is permitted to step down on any Distribution Date, the pooling and servicing agreement provides that a portion of the principal which would otherwise be distributed to the holders of the Offered Certificates on the related Distribution Date shall be distributed to the holders of the Class CE Certificates pursuant to the priorities set forth above.

With respect to each Distribution Date, the Overcollateralization Reduction Amount, after taking into account all other distributions to be made on the related Distribution Date, shall be distributed as Net Monthly Excess Cashflow pursuant to the priorities set forth above. This has the effect of decelerating the amortization of the Offered Certificates relative to the amortization of the Mortgage Loans, and of reducing the Overcollateralization Amount. However, if on any Distribution Date a Trigger Event is in effect, the Required Overcollateralization Amount will not be permitted to step down on the related Distribution Date.

Allocation of Losses; Subordination

With respect to any defaulted Mortgage Loan that is finally liquidated through foreclosure sale or disposition of the related Mortgaged Property (if acquired on behalf of the certificateholders by deed in lieu of foreclosure or otherwise), the amount of loss realized, if any, will equal the portion of the unpaid principal balance remaining, if any, plus interest thereon through the last day of the month in which the related Mortgage Loan was finally liquidated or charged-off, after application of all amounts recovered (net of amounts reimbursable to the Servicer or the Master Servicer for P&I Advances, servicing advances and other related expenses, including attorneys’ fees) towards interest and principal owing on the Mortgage Loan. The amount of loss realized and any Bankruptcy Losses are referred to in this free writing prospectus as “Realized Losses.” In the event that amounts recovered in connection with the final liquidation of a defaulted Mortgage Loan are insufficient to reimburse the Servicer or the Master Servicer for P&I Advances, servicing advances and unpaid servicing fees, these amounts may be reimbursed to the Servicer or the Master Servicer out of any funds in the collection account prior to any remittance to the Securities Administrator of funds for distribution on the certificates. In addition, to the extent the Servicer receives Subsequent Recoveries with respect to any defaulted Mortgage Loan, the amount of the Realized Loss with respect to that defaulted Mortgage Loan will be reduced to the extent such recoveries are applied to reduce the Certificate Principal Balance of any class of Certificates on any Distribution Date.

142

The pooling and servicing agreement does not permit the allocation of Realized Losses to the Class A Certificates or Class P Certificates. Investors in the Class A Certificates should note that although Realized Losses cannot be allocated to the Class A Certificates, under certain loss scenarios there will not be enough principal and interest on the Mortgage Loans to pay the Class A Certificates all interest and principal amounts to which they are then entitled.

Except as described below, once Realized Losses have been allocated to the Mezzanine Certificates, such amounts with respect to such certificates will no longer accrue interest, and such amounts will not be reinstated thereafter (except in the case of Subsequent Recoveries as described below). However, Allocated Realized Loss Amounts may be paid to the holders of the Mezzanine Certificates from Net Monthly Excess Cashflow and from amounts received by the Securities Administrator under the Interest Rate Swap Agreement, according to the priorities set forth under “—Overcollateralization Provisions” and “—The Interest Rate Swap Agreement” above.

Any allocation of a Realized Loss to a Mezzanine Certificate will be made by reducing the Certificate Principal Balance of that Certificate by the amount so allocated as of the Distribution Date in the month following the calendar month in which the Realized Loss was incurred. Notwithstanding anything to the contrary described in this free writing prospectus, in no event will the Certificate Principal Balance of any Mezzanine Certificate be reduced more than once in respect of any particular amount both (i) allocable to such certificate in respect of Realized Losses and (ii) payable as principal to the holder of such certificate from Net Monthly Excess Cashflow and from amounts on deposit in the Supplemental Interest Trust.

A “Bankruptcy Loss” is a Deficient Valuation or a Debt Service Reduction. With respect to any Mortgage Loan, a “Deficient Valuation” is a valuation by a court of competent jurisdiction of the Mortgaged Property in an amount less than the then outstanding indebtedness under the Mortgage Loan, which valuation results from a proceeding initiated under the United States Bankruptcy Code. A “Debt Service Reduction” is any reduction in the amount which a mortgagor is obligated to pay on a monthly basis with respect to a Mortgage Loan as a result of any proceeding initiated under the United States Bankruptcy Code, other than a reduction attributable to a Deficient Valuation.

In the event that the Servicer receives any Subsequent Recoveries, such Subsequent Recoveries will be distributed as part of the Available Distribution Amount in accordance with the priorities described under “Description of the Certificates” in this free writing prospectus and the Certificate Principal Balance of each class of Mezzanine Certificates that has been reduced by the allocation of a Realized Loss to such certificate will be increased, in order of seniority, by the amount of such Subsequent Recoveries but not by more than the amount of Realized Losses previously allocated to reduce the Certificate Principal Balance of such certificate, and only to the extent that such certificate has not been reimbursed for the amount of such Realized Loss (or any portion thereof) allocated to such certificate from Net Monthly Excess Cashflow as described under “Description of the Certificates—Overcollateralization Provisions” and from amounts on deposit in the Supplemental Interest Trust as described under “Description of the Certificates—The Interest Rate Swap Agreement” in this free writing prospectus. Holders of such certificates will not be entitled to any payment in respect of current interest on the amount of such increases for any Interest Accrual Period preceding the Distribution Date on which such increase occurs.

143

SERVICING OF THE MORTGAGE LOANS

General

Primary servicing of the Mortgage Loans will be provided by Ocwen Loan Servicing, LLC (“Ocwen”). Ocwen will service the Mortgage Loans in accordance with the Pooling and Servicing Agreement. The Master Servicer will be required to monitor Ocwen’s performance under the Pooling and Servicing Agreement. In the event of a default by Ocwen under the Pooling and Servicing Agreement, the Master Servicer shall enforce any remedies against Ocwen.

The information set forth in the following paragraphs has been provided by Ocwen.

Ocwen Loan Servicing, LLC (“Ocwen”), a Delaware limited liability company, has its primary servicing operations in Orlando, Florida and its corporate offices in West Palm Beach, Florida. Ocwen is a wholly owned subsidiary of Ocwen Financial Corporation, a public financial services holding company (“OCN”) headquartered in West Palm Beach, Florida. OCN’s primary businesses are the servicing, special servicing and resolution of nonconforming, subperforming and nonperforming residential and commercial mortgage loans for third parties, as well as providing loan servicing technology and business-to-business e-commerce solutions for the mortgage and real estate industries.

As of September 30, 2006, OCN had approximately $1.913 billion in assets, including $192.2 million of cash, approximately $1.374 billion in liabilities and approximately $537.2 million in equity. For the quarter ended September 30, 2006, OCN’s net income was approximately $17.0 million, as compared to approximately $159.1 million (including a tax benefit of $141.7 million) reported for the quarter ended June 30, 2006.

147

Ocwen is rated as a “Strong” residential subprime servicer and residential special servicer by Standard & Poor’s and has an “RPS2” rating as a subprime servicer and an “RSS2” rating as special servicer from Fitch Ratings. Ocwen is also rated “SQ2-” (“Above Average”) as a primary servicer of subprime loans and “SQ2” (“Above Average”) as a special servicer by Moody’s Investors Service, Inc. On April 23, 2004, Standard & Poor’s placed its “Strong” residential subprime servicer and residential special servicer ratings assigned to Ocwen on “Credit Watch with negative implications.” Ocwen is an approved Freddie Mac and Fannie Mae seller/servicer.

Ocwen, as successor in interest to Ocwen Federal Bank, and OCN are defendants in several potential class action lawsuits challenging Ocwen’s mortgage servicing practices. To date, no such lawsuit has been certified by any court as a class action. On April 13, 2004, these lawsuits were consolidated in a single proceeding in the United States District Court for the District of Illinois under caption styled: Ocwen Federal Bank FSB Mortgage Servicing Litigation, MDL Docket No. 1604. Ocwen believes that its servicing practices comply with legal requirements and is vigorously defending against such lawsuits. Ocwen is also subject to various other routine pending litigation in the ordinary course of its business. While the outcome of litigation is always uncertain, Ocwen’s management is of the opinion that the resolution of any of these claims and lawsuits will not have a material adverse effect on the results of its operations or financial condition or its ability to service the mortgage loans.

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 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 believes that the judgment is against the weight of evidence and contrary to law and that the attorneys’ fees award, which comprises $1.1 million of the judgment should be reduced as impermissibly excessive. Ocwen appealed the decision and will continue to vigorously defend this matter.

On September 13, 2006, a complaint was filed in the United States Bankruptcy Court in Delaware against Ocwen and other parties by the Chapter 7 Trustee of American Business Financial Services, Inc. and its subsidiaries (collectively, “ABFS”) alleging various improper activities and conduct that have harmed ABFS. Claims against Ocwen include damages resulting from improperly servicing mortgage loans included in ABFS-sponsored securitizations and from actions relating to the acquisition of servicing rights from ABFS on those securitizations. Ocwen believes the claims made by ABFS are without merit and intends to vigorously defend the matter.

Ocwen, including its predecessors, has significant experience in servicing residential and commercial mortgage loans and has been servicing residential mortgage loans since 1988, and non-prime mortgage loans since 1994. Ocwen is one of the largest third-party subprime mortgage loan servicers in the United States. OCN and its related companies currently employ more than 3,500 people worldwide with domestic residential mortgage loan servicing and processing centers in Orlando, Florida and Chicago, Illinois and related international offices in Bangalore and Mumbai, India. Ocwen specializes in the management of sub-performing and non-performing assets, including severely delinquent and labor-intensive mortgage loans and REO assets. Ocwen’s servicing experience generally includes collection, loss mitigation, default reporting, bankruptcy, foreclosure and REO property management.

As of September 30, 2006, Ocwen provided servicing for residential mortgage loans with an aggregate unpaid principal balance of approximately $50.8 billion, substantially all of which are being serviced for third parties, including loans in over 250 securitizations. The table below sets forth the aggregate unpaid principal balance of the subprime mortgage loans serviced by Ocwen at the end of each of the indicated periods.

Ocwen’s Delinquency and Foreclosure Experience

The following tables set forth, for the subprime mortgage loan servicing portfolio serviced by Ocwen, certain information relating to the delinquency, foreclosure, REO and loss experience with respect to such mortgage loans (including loans in foreclosure in Ocwen’s servicing portfolio (which portfolio does not include mortgage loans that are subserviced by others)) at the end of the indicated periods. The indicated periods of delinquency are based on the number of days past due on a contractual basis. No mortgage loan is considered delinquent for these purposes until it is one month past due on a contractual basis. Ocwen’s portfolio may differ significantly from the mortgage loans in the mortgage loan pool in terms of interest rates, principal balances, geographic distribution, types of properties, lien priority, origination and underwriting criteria, prior servicer performance and other possibly relevant characteristics. There can be no assurance, and no representation is made, that the delinquency and foreclosure experience with respect to the mortgage loans in the mortgage loan pool will be similar to that reflected in the table below, nor is any representation made as to the rate at which losses may be experienced on liquidation of defaulted mortgage loans in the mortgage loan pool. The actual delinquency experience with respect to the mortgage loans in the mortgage loan pool will depend, among other things, upon the value of the real estate securing such mortgage loans in the mortgage loan pool and the ability of the related borrower to make required payments. It should be noted that if the residential real estate market should experience an overall decline in property values, the actual rates of delinquencies and foreclosures could be higher than those previously experienced by Ocwen. In addition, adverse economic conditions may affect the timely payment by borrowers of scheduled payments of principal and interest on the mortgage loans in the mortgage loan pool and, accordingly, the actual rates of delinquencies and foreclosures with respect to the mortgage loan pool. Finally, the statistics shown below represent the delinquency experience for Ocwen’s mortgage servicing portfolio only for the periods presented, whereas the aggregate delinquency experience with respect to the mortgage loans comprising the mortgage loan pool will depend on the results obtained over the life of the mortgage loan pool.

Ocwen’s Policies and Procedures

Upon boarding a mortgage loan, various types of information are automatically loaded into Ocwen’s mortgage loan servicing system (“REALServicing”). Ocwen then makes all reasonable efforts to collect the contractual mortgage loan payments that are due by the borrower pursuant to the applicable mortgage loan documents and, consistent with the Pooling and Servicing Agreement, will follow such collection procedures that are customary with respect to comparable mortgage loans.

Ocwen’s collection policy seeks to identify payment problems at the early stage of delinquency and, if necessary, to address such delinquency in order to preserve the equity of a pre-foreclosure mortgage property. Ocwen uses a consistent application, a proactive consulting approach, defined call strategies, and enhanced payment methods to assist the collection process. On a monthly basis, borrowers are mailed their monthly statement in advance of the due date. All borrowers can obtain loan information and make payments via web access (www.ocwen.com), as well as direct dial customer service.

Ocwen utilizes multiple strategies in order to identify payment problems while working with borrowers to make their monthly payment in a timely manner. The potential for losses is mitigated using internal proprietary models to project performance and required advances and to assist in identifying workout options. On a monthly basis the delinquency status is determined for each mortgage loan. A collector then calls the borrower to make payment arrangements. If payments have not been collected by the date a late charge becomes effective, a standard reminder letter is mailed to the borrower.

Subject to the limitations set forth in the Pooling and Servicing Agreement, Ocwen, in its discretion, may waive any assumption fees, late payment charges, or other charges in connection with the underlying mortgage loans, modify any term of a mortgage loan, consent to the postponement of strict compliance with any such terms, or grant indulgence to any borrower.

If a loan becomes non-performing, projections are conducted on a monthly basis using proprietary cash-flow models that help determine the recoverability of losses and the preservation of equity. Various marketing scenarios are analyzed using an updated broker price opinion and appraisals to assist in projecting property cash flow. If the projected loss severity reaches or exceeds 100% (proceeds less expenses) then future advances on the mortgage loan are deemed non-recoverable and a recommendation is then made to stop making such advances. A more in-depth analysis is conducted to determine if charge-off is appropriate.

If reasonable collection efforts have not been successful, Ocwen will determine whether a foreclosure proceeding is appropriate. Additional proprietary models are used to project future costs that may occur while completing foreclosure and ultimately liquidating the loan.

Ocwen complies with standard servicing practices in utilizing customary external vendors for such functions as obtaining property appraisals, broker price opinions, property preservation functions and legal counsel. These functions are monitored and reviewed by Ocwen.

Over the past three years, there has been no material changes in Ocwen’s servicing policies and procedures.

Servicing and Other Compensation and Payment of Expenses

The Servicer will provide customary servicing functions with respect to the Mortgage Loans. Among other things, the Servicer is obligated under some circumstances to make P&I Advances with respect to the Mortgage Loans. In managing the liquidation of defaulted Mortgage Loans, the Servicer will have sole discretion to take such action in maximizing recoveries to the certificateholders including, without limitation, selling defaulted Mortgage Loans and REO properties as described in the Pooling and Servicing Agreement.

152

The principal compensation to be paid to the Servicer in respect of the servicing activities performed by the Servicer will be a servicing fee (the “Servicing Fee”) calculated at a per annum rate (the “Servicing Fee Rate”) equal to 0.50% with respect to each Mortgage Loan on the Scheduled Principal Balance of each such Mortgage Loan. As additional servicing compensation, the Servicer is entitled to retain all servicing-related fees, including assumption fees, modification fees, extension fees, non-sufficient funds fees, late payment charges and other ancillary fees and charges in respect of the Mortgage Loans (with the exception of Prepayment Charges, which will be distributed to the holders of the Class P Certificates), to the extent collected from mortgagors, together with any interest or other income earned on funds held in the collection account and any related escrow account.

The Servicer is entitled to retain any Prepayment Interest Excess (as defined in the Pooling and Servicing Agreement) with respect to the Mortgage Loans. The Servicer is obligated to pay insurance premiums and other ongoing expenses associated with the related Mortgage Loans in connection with its responsibilities under the Pooling and Servicing Agreement and is entitled to reimbursement for these expenses as provided in the Pooling and Servicing Agreement. See “Description of the Agreements-Material Terms of the Pooling and Servicing Agreements and Underlying Servicing Agreements-Retained Interest, Servicing Compensation and Payment of Expenses” in the prospectus for information regarding expenses payable by the Servicer.

Payments on Mortgage Loans; Deposits to Collection Account

The Servicer will establish and maintain or cause to be maintained a separate trust account (the “Collection Account”) for the benefit of the certificateholders. The Collection Account will be an Eligible Account (as defined in the Pooling and Servicing Agreement). Upon receipt by the Servicer of amounts in respect of the Mortgage Loans (excluding amounts representing the Servicing Fees or other servicing compensation, reimbursement for P&I Advances and servicing advances and insurance proceeds to be applied to the restoration or repair of a Mortgaged Property or similar items), the Servicer will deposit such amounts in the Collection Account. Amounts so deposited by the Servicer may be invested in Permitted Investments maturing no later than one Business Day prior to the date on which the amount on deposit therein is required to be remitted to the Securities Administrator. All investment income on funds in the Collection Account shall be for the benefit of the Servicer.

Any one or more of the following obligations or securities held in the name of the Trustee for the benefit of the certificateholders will be considered a Permitted Investment:

(i) obligations of the United States or any agency thereof, provided such obligations are backed by the full faith and credit of the United States;

(ii) general obligations of or obligations guaranteed by any state of the United States or the District of Columbia receiving the highest long-term debt rating of each rating agency, or such lower rating as will not result in the downgrading or withdrawal of the ratings then assigned to the certificates by each rating agency, as evidenced in writing;

(iii) commercial or finance company paper which is then receiving the highest commercial or finance company paper rating of each rating agency rating such paper, or such lower rating as will not result in the downgrading or withdrawal of the ratings then assigned to the certificates by each rating agency, as evidenced in writing;

153

(iv) certificates of deposit, demand or time deposits, or bankers’ acceptances issued by any depository institution or trust company incorporated under the laws of the United States or of any state thereof and subject to supervision and examination by federal and/or state banking authorities (including the trustee in its commercial banking capacity), provided that the commercial paper and/or long term unsecured debt obligations of such depository institution or trust company are then rated one of the two highest long-term and the highest short-term ratings of each such rating agency for such securities, or such lower ratings as will not result in the downgrading or withdrawal of the rating then assigned to the certificates by any rating agency, as evidenced in writing;

(v) guaranteed reinvestment agreements issued by any bank, insurance company or other corporation containing, at the time of the issuance of such agreements, such terms and conditions as will not result in the downgrading or withdrawal of the rating then assigned to the certificates by each rating agency, as evidenced in writing;

(vi) repurchase obligations with respect to any security described in clauses (i) and (ii) above, in either case entered into with a depository institution or trust company (acting as principal) described in clause (v) above;

(vii) securities (other than stripped bonds, stripped coupons or instruments sold at a purchase price in excess of 115% of the face amount thereof) bearing interest or sold at a discount issued by any corporation incorporated under the laws of the United States or any state thereof which, at the time of such investment, have one of the two highest short term ratings of each rating agency (except if the rating agency is Moody’s, such rating will be the highest commercial paper rating of Moody’s for any such securities), or such lower rating as will not result in the downgrading or withdrawal of the rating then assigned to the certificates by each rating agency, as evidenced by a signed writing delivered by each rating agency;

(viii) interests in any money market fund (including any such fund managed or advised by the trustee or any affiliate thereof) which at the date of acquisition of the interests in such fund and throughout the time such interests are held in such fund has the highest applicable short term rating by each rating agency or such lower rating as will not result in the downgrading or withdrawal of the ratings then assigned to the certificates by each rating agency, as evidenced in writing;

(ix) short term investment funds sponsored by any trust company or banking association incorporated under the laws of the United States or any state thereof (including any such fund managed or advised by the Trustee or the Master Servicer or any affiliate thereof) which on the date of acquisition has been rated by each rating agency in their respective highest applicable rating category or such lower rating as will not result in the downgrading or withdrawal of the ratings then assigned to the certificates by each rating agency, as evidenced in writing; and

(x) such other investments having a specified stated maturity and bearing interest or sold at a discount acceptable to each rating agency and as will not result in the downgrading or withdrawal of the rating then assigned to the certificates by any rating agency, as evidenced by a signed writing delivered by each rating agency.

Prepayment Interest Shortfalls and Compensating Interest

When a principal prepayment in full is made on a Mortgage Loan, the mortgagor is charged interest only for the period from the Due Date of the preceding monthly payment up to the date of the prepayment, instead of for a full month. When a partial principal prepayment is made on a Mortgage Loan, the mortgagor is not charged interest on the amount of the prepayment for the month in which the prepayment is made. In addition, the application of the Servicemembers Civil Relief Act (the “Relief Act”) and similar state or local laws to any Mortgage Loan could adversely affect, for an indeterminate period of time, the ability of the Servicer to collect full amounts of interest on such Mortgage Loans. The Servicer is obligated to pay from its own funds only those interest shortfalls attributable to voluntary principal prepayments in full by the mortgagors on the Mortgage Loans received from the 16th day of the month prior to the month of the related Distribution Date to the last day of such prior month; provided, however that the obligation of the Servicer to remit the amount of any shortfall in interest resulting from a principal prepayment in full on a Mortgage Loan shall be limited to the aggregate Servicing Fee (as defined in this free writing prospectus) payable to the Servicer for the related Due Period. The Servicer will not remit any shortfalls in interest attributable to the application of the Relief Act or any similar state or local laws. Any interest shortfalls attributable to voluntary principal prepayments required to be funded but not funded by the Servicer are required to be paid by the Master Servicer, but only to the extent that such amount does not exceed the master servicing fee payable to the Master Servicer for the applicable Distribution Date. Accordingly, the effect of interest shortfalls resulting from principal prepayments in full or in part on the Mortgage Loans (each, a “Prepayment Interest Shortfall”) to the extent that they exceed any payments by the Master Servicer or the Servicer (“Compensating Interest”) or any shortfalls resulting from the application of the Relief Act or similar state or local laws, will be to reduce the aggregate amount of interest collected that is available for distribution to certificateholders. Any such shortfalls will be allocated among the certificates as provided under “Description of the Certificates—Interest Distributions on the Offered Certificates” and “— Overcollateralization Provisions” in this free writing prospectus. See “Certain Legal Aspects of the Mortgage Loans—Servicemembers Civil Relief Act” in the prospectus.

154

Advances

Subject to the limitations set forth in the following paragraph, the Servicer will be obligated to advance or cause to be advanced on or before each Servicer Remittance Date its own funds, or funds in the Collection Account that are not included in the Available Distribution Amount for the Distribution Date. The amount of the related advance will be equal to the aggregate of all scheduled payments of principal and interest, net of the Servicing Fee, that were due during the related Due Period on the related Mortgage Loans and that were delinquent on the related Determination Date, plus amounts representing assumed payments not covered by any current net income on the Mortgaged Properties acquired by foreclosure or deed in lieu of foreclosure (net of the Servicing Fees). These advances are referred to in this free writing prospectus as “P&I Advances”. ”. In addition, the Servicer will be obligated to advance or cause to be advanced, from time to time, its own funds, or funds in the Collection Account that are not included in the Available Distribution Amount for the Distribution Date, as servicing advances pursuant to the Pooling and Servicing Agreement.

P&I Advances are required to be made only to the extent they are deemed by the Servicer to be recoverable from related late collections, insurance proceeds or liquidation proceeds on the related Mortgage Loan. The purpose of making the P&I Advances is to maintain a regular cash flow to the certificateholders, rather than to guarantee or insure against losses. The Servicer will not be required to make any P&I Advances with respect to reductions in the amount of the monthly payments on any Mortgage Loans due to bankruptcy proceedings or the application of the Relief Act or similar state or local laws. All P&I Advances will be reimbursable to the Servicer or the Master Servicer from late collections, insurance proceeds and liquidation proceeds from the Mortgage Loan as to which the unreimbursed P&I Advance was made. In addition, any P&I Advances previously made in respect of any Mortgage Loan that are deemed by the Servicer or the Master Servicer to be nonrecoverable from related late collections, insurance proceeds or liquidation proceeds may be reimbursed to the Servicer or the Master Servicer out of any funds in the Collection Account prior to the distributions on the certificates. In addition, the Servicer may, as provided in the Pooling and Servicing Agreement, withdraw from the Collection Account funds that are not included in the Available Distribution Amount for the Distribution Date to reimburse itself for certain outstanding advances, which shall include P&I Advances; provided that such amounts used by the Servicer to reimburse itself for any such outstanding advances shall be replaced by the Servicer by deposit in the Collection Account no later than the Servicer Remittance Date immediately following the Due Period or Prepayment Period for which such amounts relate. In the event that the Servicer fails in its obligation to make any required P&I Advance, a successor servicer will be obligated to make the P&I Advance on the Distribution Date for which the Servicer was required to make such P&I Advance, to the extent required in the Pooling and Servicing Agreement.

155

In addition, investors should note that the Servicer made servicing advances on the Mortgage Loans prior to the Cut-off Date in the amount of approximately $ 44,165. Such servicing advances made in respect of any Mortgage Loan that are deemed by the Servicer to be nonrecoverable from related late collections, insurance proceeds or liquidation proceeds may be reimbursed to the Servicer out of any funds in the Collection Account prior to the distributions on the certificates.

In the event that a Balloon Loan is not paid in full on its maturity date, the Servicer will also be obligated to make advances with respect to the assumed monthly payments that would have been due on such Balloon Loan based upon the original amortization schedule for the loan, unless the Servicer determines that the advance would not be recoverable. In no event will the Servicer be obligated to advance the balloon payment due on any Balloon Loan.

Upon an Event of Default by the Servicer under the Pooling and Servicing Agreement, the Master Servicer may terminate the Servicer and appoint, or under circumstances, Ocwen or its designee may appoint. a successor servicer. Such successor servicer must meet the requirements for successor servicers under the Pooling and Servicing Agreement (including receipt of confirmation from each Rating Agency that the appointment of such successor servicer would not lead to a qualification, downgrade or withdrawal of the ratings then assigned to the Offered Certificates in accordance with the terms and conditions of the Pooling and Servicing Agreement). See “Certain Matters Regarding Ocwen Loan Servicing, LLC as Servicer” in this free writing prospectus.

The Pooling and Servicing Agreement also provides that the Servicer may enter into a facility with any person which provides that such person may fund P&I Advances or servicing advances, although no such facility shall reduce or otherwise affect the obligations of the Servicer to fund such P&I Advances or servicing advances. Any P&I Advances or servicing advances funded by an advancing person will be reimbursed to the advancing person in the same manner as reimbursements would be made to the Servicer. The Pooling and Servicing Agreement also provides that the Servicer may pledge its servicing rights under the Pooling and Servicing Agreement to one or more lenders.

Modifications

In instances in which a Mortgage Loan is in default or if default is reasonably foreseeable, and if determined by the Servicer to be in the best interest of the certificateholders, the Servicer may permit servicing modifications of the Mortgage Loan rather than proceeding with foreclosure. However, the Servicer’s ability to perform servicing modifications will be subject to some limitations, including but not limited to the following: any amounts added to the principal balance of the Mortgage Loan, or capitalized amounts added to the Mortgage Loan, will be required to be fully amortized over the remaining term, or the extended term, of the Mortgage Loan; all capitalizations are to be implemented in accordance with the Servicer’s standards and may be implemented only by the Servicer for that purpose. Pursuant to the terms of the Pooling and Servicing Agreement, unless a Mortgage Loan is in default or such default is reasonably foreseeable, no servicing modification with respect to a Mortgage Loan will have the effect of (i) reducing the mortgage rate, (ii) reducing or increasing the principal balance (except for reductions resulting from actual payments of principal) or (iii) changing the final maturity date on such Mortgage Loan (subject to certain exceptions) or that would both (A) effect an exchange or reissuance of such Mortgage Loan under Section 1001 of the Code (or final, temporary or proposed Treasury regulations promulgated thereunder) and (B) cause any Trust REMIC created under the Pooling and Servicing Agreement to fail to qualify as a REMIC under the Code or the imposition of any tax on “prohibited transactions” or “contributions after the startup date” under the REMIC Provisions.

156

Any advances made on any Mortgage Loan will be reduced to reflect any related servicing modifications previously made. The Mortgage Rate and net Mortgage Rate as to any Mortgage Loan will be deemed not reduced by any servicing modification, so that the calculation of the Interest Distribution Amount (as defined in this free writing prospectus) payable on the Offered Certificates will not be affected by the servicing modification.

Evidence as to Compliance

The Pooling and Servicing Agreement will provide that each year on or before the date set forth in the Pooling and Servicing Agreement, beginning with the first year after the year in which the Cut-off Date occurs, each party responsible for the servicing function will provide to the Depositor, the Master Servicer and the Securities Administrator a report on an assessment of compliance with the minimum servicing criteria established in Item 1122(a) of Regulation AB (the “AB Servicing Criteria”). The AB Servicing Criteria include specific criteria relating to the following areas: general servicing considerations, cash collection and administration, investor remittances and reporting, and pool asset administration. Such report will indicate that the AB Servicing Criteria were used to test compliance on a platform level basis and will set out any material instances of noncompliance.

The Pooling and Servicing Agreement will also provide that the each party responsible for the servicing function will deliver along with its report on assessment of compliance, an attestation report from a firm of independent public accountants on the assessment of compliance with the AB Servicing Criteria.

The Pooling and Servicing Agreement will also provide for delivery to the Master Servicer, the Securities Administrator and the Depositor, each year on or before the date set forth in the pooling and servicing agreement, of a separate annual statement of compliance from each entity responsible for the servicing function to the effect that, to the best knowledge of the signing officer, the Servicer has fulfilled in all material respects its obligations under the Pooling and Servicing Agreement throughout the preceding year or, if there has been a material failure in the fulfillment of any obligation, the statement shall specify such failure and the nature and status thereof. This statement may be provided as a single form making the required statements as to more than one pooling and servicing agreement.

Copies of the annual reports of assessment of compliance, attestation reports, and statements of compliance may be obtained by securityholders without charge upon written request to the Master Servicer at the address of the Master Servicer set forth under “The Securities Administrator, the Master Servicer and the Custodians” in this free writing prospectus. These items will be filed with the Issuing Entity’s annual report on Form 10-K, to the extent required under Regulation AB.

Files are segregated by transaction or investor. Wells Fargo Bank has been engaged in the mortgage document custody business for more than 25 years. Wells Fargo Bank maintains document custody facilities in its Minneapolis, Minnesota headquarters and in three regional offices located in Richfield, Minnesota, Irvine, California, and Salt Lake City, Utah. As of December 31, 2006, Wells Fargo Bank maintains mortgage custody vaults in each of those locations with an aggregate capacity of over eleven million files.

Wells Fargo Bank serves or may have served within the past two years as loan file custodian for various mortgage loans owned by the Sponsor or an affiliate of the Sponsor and anticipates that one or more of those mortgage loans may be included in the Trust. The terms of any custodial agreement under which those services are provided by Wells Fargo are customary for the mortgage-backed securitization industry and provide for the delivery, receipt, review and safekeeping of mortgage loan files.

Approximately 90.45% of the mortgage loan files with respect to the Mortgage Loans, by aggregate principal balance as of the Cut-off Date, will be held by Wells Fargo Bank pursuant to a custodial agreement to be entered into among HSBC Bank USA, National Association, as Trustee, Wells Fargo Bank, as a custodian, and the Servicer.

Deutsche Bank National Trust Company

General

The information set forth in the following paragraph has been provided by Deutsche Bank National Trust Company (“DBNTC”).

DBNTC has performed a custodial role in numerous mortgage-backed transactions since 1991. DBNTC will maintain the mortgage files in secure, fire-resistant facilities. DBNTC will not physically segregate the mortgage files from other mortgage files in DBNTC’s custody but will be kept in shared facilities. However, DBNTC’s proprietary document tracking system will show the location within DBNTC’s facilities of each mortgage file and will show that the mortgage loan documents are held by the Trustee on behalf of the trust. DBNTC has no pending legal proceedings that would materially affect its ability to perform its duties as a custodian on behalf of the Holders. DBNTC may perform certain of its obligations through one or more third party vendors. However, DBNTC shall remain liable for the duties and obligations required of it under its custodial agreement.

DBNTC is providing the information in the foregoing paragraph at the Depositor’s request in order to assist the Depositor with the preparation of its disclosure documents to be filed with the SEC pursuant to Regulation AB. Otherwise, DBNTC has not participated in the preparation of such disclosure documents and assumes no responsibility or liability for their contents.

Approximately 9.55% of the mortgage loan files with respect to the Mortgage Loans by aggregate principal balance as of the Cut-off Date, will be held by DBNTC pursuant to a custodial agreement to be entered into among HSBC Bank USA, National Association, as Trustee, DBNTC, as a custodian, and the Servicer.

Master Servicing and Other Compensation and Payment of Expenses

The principal compensation to be paid to the Master Servicer in respect of its master servicing activities for the certificates will be a master servicing fee equal to one-twelfth of the product of 0.0035% multiplied by the Scheduled Principal Balance of the Mortgage Loans as of the Due Date in the preceding calendar month. In addition, the Master Servicer will be entitled to any interest or other income earned on funds held in the Distribution Account.

In the event that the Servicer fails to pay the amount of any Prepayment Interest Shortfall required to be paid on any Distribution Date, the Master Servicer shall pay such amount up to the master servicing compensation payable to the Master Servicer on such Distribution Date.

The Distribution Account

The Securities Administrator will establish an account (the “Distribution Account”) into which will be deposited amounts remitted to it by the Servicer for distribution to certificateholders on a Distribution Date and payment of certain fees and expenses of the trust. The Distribution Account will be an Eligible Account (as defined in the Pooling and Servicing Agreement). Amounts on deposit therein may be invested in Permitted Investments (as defined under “Servicing of the Mortgage Loans—Payments on Mortgage Loans; Deposits to Collection Account” in this free writing prospectus) maturing on or before the Business Day prior to the related Distribution Date unless such Permitted Investments are invested in investments managed or advised by the Securities Administrator or an affiliate thereof, in which case such Permitted investments may mature on the related Distribution Date.

160

Transfer of Master Servicing

The Master Servicer may sell and assign its rights and delegate its duties and obligations in its entirety as Master Servicer under the Pooling and Servicing Agreement; provided, however, that: (i) the purchaser or transferee accept in writing such assignment and delegation and assume the obligations of the Master Servicer under the Pooling and Servicing Agreement (a) shall have a net worth of not less than $25,000,000 (unless otherwise approved by each Rating Agency pursuant to clause (ii) below); (b) shall be reasonably satisfactory to the Trustee (as evidenced in a writing signed by the Trustee); and (c) shall execute and deliver to the Trustee an agreement, in form and substance reasonably satisfactory to the Trustee, which contains an assumption by such Person of the due and punctual performance and observance of each covenant and condition to be performed or observed by it as Master Servicer under the Pooling and Servicing Agreement; (ii) each Rating Agency shall be given prior written notice of the identity of the proposed successor to the Master Servicer and each Rating Agency’s rating of the Certificates in effect immediately prior to such assignment, sale and delegation will not be downgraded, qualified or withdrawn as a result of such assignment, sale and delegation, as evidenced by a letter to such effect delivered to the Master Servicer and the Trustee; and (iii) the Master Servicer assigning and selling the master servicing shall deliver to the Trustee an officer’s certificate and an opinion of independent counsel, each stating that all conditions precedent to such action under the Pooling and Servicing Agreement have been completed and such action is permitted by and complies with the terms of the Pooling and Servicing Agreement. No such assignment or delegation shall affect any liability of the Master Servicer arising out of acts or omissions prior to the effective date thereof.

Indemnification

The Master Servicer and any director, officer, employee or agent of the Master Servicer will be indemnified and held harmless by the trust against any loss, liability or expense as set forth in the Pooling and Servicing Agreement.

The Securities Administrator and any director, officer, employee or agent of the Securities Administrator will be indemnified and held harmless by the trust against any loss, liability or expense as set forth in the Pooling and Servicing Agreement.

The Custodians and any director, officer, employee or agent of the Custodians will be indemnified and held harmless by the trust against any loss, liability or expense as set forth in the Custodial Agreements.

THE TRUSTEE

HSBC Bank USA, National Association will be the Trustee under the Pooling and Servicing Agreement. The Depositor and the Master Servicer may maintain other banking relationships in the ordinary course of business with the Trustee. The Trustee’s corporate trust office is located at 452 Fifth Avenue, New York, New York 10018, Attention: Corporate Trust, ACE Securities Corp., Home Equity Loan Trust, Series 2007-ASAP1 or at such other address as the Trustee may designate from time to time.

HSBC Bank USA, National Association, has been and currently is, serving as Trustee for numerous securities transactions involving similar pool assets to those found in this transaction.

The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in the Pooling and Servicing Agreement as duties of the Trustee, including the following:

161

Upon receipt of all resolutions, certificates, statements, opinions, reports, documents, orders or other instruments which are specifically required to be furnished to the Trustee pursuant to the Pooling and Servicing Agreement, the Trustee (or the applicable Custodian) shall examine them to determine whether they are in the required form; provided, however, that the Trustee shall not be responsible for the accuracy or content of any resolution, certificate, statement, opinion, report, document, order or other instrument furnished hereunder; provided, further, that the Trustee shall not be responsible for the accuracy or verification of any calculation provided to it pursuant to the Pooling and Servicing Agreement.

The Trustee shall promptly remit to the Servicer any complaint, claim, demand, notice or other document (collectively, the “Notices”) delivered to the Trustee as a consequence of the assignment of any Mortgage Loan hereunder and relating to the servicing of the Mortgage Loans; provided than any such notice (i) is delivered to the Trustee at its Corporate Trust Office, (ii) contains information sufficient to permit the Trustee to make a determination that the real property to which such document relates is a Mortgaged Property (as defined in the Pooling and Servicing Agreement). The Trustee shall have no duty hereunder with respect to any Notice it may receive or which may be alleged to have been delivered to or served upon it unless such Notice is delivered to it or served upon it at its Corporate Trust Office and such Notice contains the information required pursuant to clause (ii) of the preceding sentence.

Except for those actions that the Trustee is required to take under the Pooling and Servicing Agreement, the Trustee shall not have any obligation or liability to take any action or to refrain from taking any action in the absence of written direction as provided in the Pooling and Servicing Agreement.

If an Event of Default has occurred and has not been cured or waived, the Trustee shall exercise such of the rights and powers vested in it by the Pooling and Servicing Agreement, using the same degree of care and skill in their exercise, as a prudent person would exercise under the circumstances in the conduct of his own affairs.

Without limiting the generality of the foregoing, if an Event of Default shall occur, the Trustee shall, at the direction of at least 51% of the Voting Rights, by notice in writing to the Master Servicer and to the Depositor, with a copy to each Rating Agency, terminate all of the rights and obligations of the Master Servicer in its capacity as Master Servicer under the Pooling and Servicing Agreement, to the extent permitted by law, and in and to the Mortgage Loans and the proceeds thereof. On or after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer with respect to the Certificates (other than as a holder of any Certificate) or the Mortgage Loans or otherwise including, without limitation, the compensation payable to the Master Servicer under the Pooling and Servicing Agreement, shall pass to and be vested in the Trustee, and, without limitation, the Trustee shall be authorized and empowered, as attorney-in-fact or otherwise, to execute and deliver, on behalf of and at the expense of the Master Servicer, any and all documents and other instruments and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents, or otherwise. Notwithstanding the foregoing, The Trustee may, if is shall be unwilling to so to act, or shall, if it is legally unable to act, appoint, or petition a court of competent jurisdiction to appoint, a successor master servicer in accordance with the terms of the Pooling and Servicing Agreement.

To the extent that the costs and expenses of the Trustee related to the termination of the Master Servicer, appointment of a successor master servicer or the transfer and assumption of the master servicing by the Trustee (including, without limitation, (i) all legal costs and expenses and all due diligence costs and expenses associated with an evaluation of the potential termination of the Master Servicer as a result of an Event of Default and (ii) all costs and expenses associated with the complete transfer of the master servicing, including all servicing files and all servicing data and the completion, correction or manipulation of such servicing data as may be required by the successor master servicer to correct any errors or insufficiencies in the servicing data or otherwise to enable the successor master servicer to master service the Mortgage Loans in accordance with the Pooling and Servicing Agreement) are not fully and timely reimbursed by the terminated master servicer, the Trustee shall be entitled to reimbursement of such costs and expenses from the Distribution Account.

162

For further discussion of the duties of the Trustee, please see “Description of the Agreements—Material Terms of the Pooling and Servicing Agreements and Underlying Servicing Agreements—Duties of the Trustee” in the prospectus.

The Master Servicer will pay the Trustee the trustee’s fee in respect of its obligations under the Pooling and Servicing Agreement. The Pooling and Servicing Agreement will provide that the Trustee and any director, officer, employee or agent of the Trustee will be indemnified by the trust and will be held harmless against any loss, liability, expense or cost including, without limitation, attorneys fees and expenses (not including expenses and disbursements incurred or made by the Trustee in the ordinary course of the Trustee’s performance in accordance with the provisions of the Pooling and Servicing Agreement) incurred by the Trustee in connection with any pending or threatened legal action or arising out of or in connection with the acceptance or administration of its obligations and duties under the Pooling and Servicing Agreement, the Certificates or the Custodial Agreements, other than any loss, liability or expense (i) resulting from a breach of the related obligations and duties of the Servicer under the Pooling and Servicing Agreement (for which the Trustee receives indemnity from the Servicer) or (ii) incurred by reason of willful misfeasance, bad faith or negligence in the performance of the Trustee’s duties under the Pooling and Servicing Agreement, the Certificates or the Custodial Agreements or by reason of reckless disregard, of the Trustee’s obligations and duties under the Pooling and Servicing Agreement, the Certificates or the Custodial Agreements.

The Trustee may resign at any time, in which event the Depositor will be obligated to appoint a successor trustee. The Depositor may also remove the Trustee if the Trustee ceases to be eligible to continue under the Pooling and Servicing Agreement or if the Trustee becomes insolvent. Upon becoming aware of the circumstances, the Depositor will be obligated to appoint a successor trustee. The Trustee may also be removed at any time by the holders of the certificates evidencing not less a majority of the voting rights in the trust fund. Any resignation or removal of the Trustee and appointment of a successor trustee will not become effective until acceptance of the appointment by the successor trustee. If the Trustee resigns, the expenses associated with the change of trustee in connection with such resignation will be paid by the former trustee. If the Depositor removes the Trustee, the expenses associated with the change of trustee in connection with such removal will be paid from the Distribution Account. If the Trustee is removed by holders of certificates, such holders shall be responsible for paying any compensation payable to a successor trustee, in excess of the amount paid to the predecessor trustee.

THE CREDIT RISK MANAGER

Clayton Fixed Income Services Inc., as credit risk manager for the trust (the “Credit Risk Manager”) will monitor the performance of the Servicer, and make recommendations to the Servicer and/or Master Servicer regarding certain delinquent and defaulted Mortgage Loans and will report to the Depositor on the performance of the Mortgage Loans, pursuant to a Credit Risk Management Agreement to be entered into by the Credit Risk Manager and the Servicer and/or Master Servicer on or prior to the Closing Date. The Credit Risk Manager will rely upon mortgage loan data that is provided to it by the Servicer and/or Master Servicer in performing its advisory and monitoring functions. The Credit Risk Manager will be entitled to receive a “Credit Risk Manager’s Fee” until the termination of the trust or until its removal by a vote of at least 66 2/3% of the Certificateholders. Such fee will be paid by the trust and will be equal to one-twelfth of the product of 0.0135% multiplied by the then current aggregate principal balance of the Mortgage Loans.

163

POOLING AND SERVICING AGREEMENT

General

The certificates will be issued under the Pooling and Servicing Agreement, a form of which is filed as an exhibit to the registration statement. A Current Report on Form 8-K relating to the certificates containing a copy of the Pooling and Servicing Agreement as executed will be filed by the Depositor with the Securities and Exchange Commission (“SEC”) following the initial issuance of the certificates. The trust fund created under the Pooling and Servicing Agreement will consist of (i) all of the Depositor’s right, title and interest in the Mortgage Loans, the related mortgage notes, mortgages and other related documents; (ii) all payments on or collections in respect of the Mortgage Loans due after the Cut-off Date, together with any proceeds of the Mortgage Loans; (iii) any Mortgaged Properties acquired on behalf of certificateholders by foreclosure or by deed in lieu of foreclosure, and any revenues received on these mortgaged properties; (iv) the rights of the Trustee under all insurance policies required to be maintained under the Pooling and Servicing Agreement; (v) the rights of the Depositor under the Mortgage Loan Purchase Agreement; (vi) the Reserve Fund and any amounts on deposit in the Reserve Fund from time to time and any proceeds thereof; (vii) the right to any Net Swap Payment and any Swap Termination Payment made by the Swap Provider under the Interest Rate Swap Agreement; and (viii) payments made pursuant to the Cap Agreements. For the avoidance of doubt, the trust fund does not include the Supplemental Interest Trust. Reference is made to the prospectus for important information in addition to that set forth in this free writing prospectus regarding the trust fund, the terms and conditions of the Pooling and Servicing Agreement and the Offered Certificates. The Depositor will provide to a prospective or actual certificate holder without charge, on written request, a copy, without exhibits, of the Pooling and Servicing Agreement. Requests should be addressed to 6525 Morrison Blvd., Suite 318, Charlotte, North Carolina 28211.

Assignment of the Mortgage Loans

On the Closing Date, the Depositor will transfer to the trust all of its right, title and interest in and to each Mortgage Loan, the related mortgage note, mortgage, assignment of mortgage in recordable form in blank and other related documents (collectively, the “Related Documents”), including all scheduled payments with respect to each such Mortgage Loan due after the Cut-off Date. The Trustee, concurrently with such transfer, will deliver the certificates to the Depositor. Each Mortgage Loan transferred to the trust will be identified on a schedule (the “Mortgage Loan Schedule”) delivered to the Trustee and the Servicer pursuant to the Pooling and Servicing Agreement. The Mortgage Loan Schedule will include information such as the principal balance of each Mortgage Loan as of the Cut-off Date, its Mortgage Rate as well as other information with respect to each Mortgage Loan.

The Pooling and Servicing Agreement will require that, prior to the Closing Date, the Depositor will deliver or cause to be delivered to the Trustee (or the applicable Custodian, as the Trustee’s agent for such purpose) the mortgage notes endorsed in blank and the Related Documents. In lieu of delivery of original mortgages or mortgage notes, if such original is not available or lost, the Depositor may deliver or cause to be delivered true and correct copies thereof, or, with respect to a lost mortgage note, a lost note affidavit. The assignments of mortgage are generally required to be recorded by or on behalf of the Depositor in the appropriate offices for real property records, except (i) in states as to which an opinion of counsel is delivered to the effect that such recording is not required to protect the Trustee’s interest in the Mortgage Loan against the claim of any subsequent transferee or any successor to or creditor of the Depositor or the Sponsor, or (ii) with respect to any Mortgage Loan electronically registered through the Mortgage Electronic Registration Systems, Inc.

164

On or prior to the Closing Date, the Trustee or the applicable Custodian on its behalf will review the Mortgage Loans and the Related Documents pursuant to the related Custodial Agreement and, if any Mortgage Loan or Related Document is found to be defective in any material respect and such defect is not cured within 90 days following notification thereof to the Sponsor by the Trustee or the Servicer, the Sponsor will be obligated either to (i) substitute for such Mortgage Loan a Qualified Substitute Mortgage Loan; however, such substitution is permitted only within two years of the Closing Date and may not be made unless an opinion of counsel is provided to the effect that such substitution will not disqualify any of the REMICs (as defined in the Pooling and Servicing Agreement) as a REMIC or result in a prohibited transaction tax under the Code; or (ii) purchase such Mortgage Loan at a price (the “Purchase Price”) equal to the outstanding principal balance of such Mortgage Loan as of the date of purchase, plus all accrued and unpaid interest thereon, computed at the Mortgage Rate through the end of the calendar month in which the purchase is effected, plus the amount of any unpaid Servicing Fees or unreimbursed P&I Advances and servicing advances made by the Servicer plus all unreimbursed costs and damages incurred by the trust and the Trustee in connection with any violation by any such Mortgage Loan of any predatory or abusive lending law. The Purchase Price will be required to be remitted to the Servicer for deposit in the Collection Account (as defined in this free writing prospectus) for remittance to the Securities Administrator prior to the next succeeding Distribution Date after such obligation arises. The obligation of the Sponsor to repurchase or substitute for a Deleted Mortgage Loan (as defined in this free writing prospectus) is the sole remedy regarding any defects in the Mortgage Loans and Related Documents available to the certificateholders.

In connection with the substitution of a Qualified Substitute Mortgage Loan, the Sponsor will be required to remit to the Servicer for deposit in the Collection Account for remittance to the Securities Administrator prior to the next succeeding Distribution Date after such obligation arises an amount (the “Substitution Shortfall Amount”) equal to the excess of the principal balance of the related Deleted Mortgage Loan over the principal balance of such Qualified Substitute Mortgage Loan.

The Sponsor will make certain representations and warranties as to the accuracy in all material respects of certain information furnished to the Trustee with respect to each Mortgage Loan. In addition, the Sponsor will represent and warrant, as of the Closing Date, that, among other things: (i) at the time of transfer to the Depositor, the Sponsor has transferred or assigned all of its right, title and interest in each Mortgage Loan and the Related Documents, free of any lien; (ii) each Mortgage Loan complied, at the time of origination, in all material respects with applicable state and federal laws including, but not limited to, predatory lending laws; (iii) the Mortgage Loans are not subject to the requirements of the Home Ownership and Equity Protection Act of 1994 and no Mortgage Loan is classified and/or defined as a “high cost”, “covered” or “predatory” loan under any other federal, state or local law or ordinance or regulation including, but not limited to, the States of Georgia, Arkansas, Kentucky, New Jersey, New Mexico, Indiana or Illinois; and (iv) no proceeds from any Mortgage Loan were used to purchase single premium credit insurance policies as part of the origination of, or as a condition to closing, such Mortgage Loan. Upon discovery of a breach of any such representation and warranty which materially and adversely affects the interests of the certificateholders in the related Mortgage Loan and Related Documents, the Sponsor will have a period of 90 days after the earlier of discovery or receipt of written notice of the breach to effect a cure; provided, however that any breach of the representations and warranties set forth in clauses (ii), (iii) or (iv) above (or certain other representations and warranties made by the Sponsor with respect to any Group I Mortgage Loan), shall be deemed to materially and adversely affect the interests of the certificateholders in the related Group I Mortgage Loan. If the breach cannot be cured within the 90-day period, the Sponsor will be obligated to (i) substitute for such Deleted Mortgage Loan a Qualified Substitute Mortgage Loan or (ii) purchase such Deleted Mortgage Loan from the trust. The same procedure and limitations that are set forth above for the substitution or purchase of Deleted Mortgage Loans as a result of deficient documentation relating thereto will apply to the substitution or purchase of a Deleted Mortgage Loan as a result of a breach of a representation or warranty in the Mortgage Loan Purchase Agreement that materially and adversely affects the interests of the certificateholders. The Depositor will file the Mortgage Loan Purchase Agreement as an exhibit to the Pooling and Servicing Agreement with the Securities and Exchange Commission in a Current Report on Form 8-K.

165

Mortgage Loans required to be transferred to the Sponsor as described in the preceding paragraphs are referred to as “Deleted Mortgage Loans.”

Events of Default

Upon the occurrence of events of default described under “Description of the Agreements-Material Terms of the Pooling and Servicing Agreements and Underlying Servicing Agreements-Events of Default under the Agreement” and “-Rights Upon Events of Default under the Agreements” in the prospectus, the Servicer may be removed as the servicer of the Mortgage Loans in accordance with the terms of the Pooling and Servicing Agreement. As further described in, and in accordance with the provisions of, the Pooling and Servicing Agreement upon the removal of the Servicer after the occurrence of an Event of Default, a successor to the Servicer (which may be the Master Servicer) will become the successor to the Servicer under the Pooling and Servicing Agreement. See “Description of the Agreements-Material Terms of the Pooling and Servicing Agreements and Underlying Servicing Agreements-Events of Default under the Agreement” and “-Rights Upon Events of Default under the Agreements” in the prospectus.

Voting Rights

At all times, 98% of all voting rights will be allocated among the holders of the Class A Certificates, the Mezzanine Certificates and the Class CE Certificates in proportion to the then outstanding Certificate Principal Balances of their respective certificates, 1% of all voting rights will be allocated to the holders of the Class P Certificates in proportion to the then outstanding Certificate Principal Balances of their respective certificates and 1% of all voting rights will be allocated to the holders of the Residual Certificates. The initial owner of the Residual Certificates is Deutsche Bank Securities Inc.

166

Termination

The circumstances under which the obligations created by the Pooling and Servicing Agreement will terminate in respect of the certificates are described in “Description of the Securities-Termination” in the prospectus. The Master Servicer will have the right to purchase all remaining Mortgage Loans on a servicing retained basis and any properties acquired in respect thereof and thereby effect early retirement of the certificates on any Distribution Date following the Due Period during which the aggregate principal balance of the Mortgage Loans and properties acquired in respect thereof remaining in the trust fund at the time of purchase is reduced to less than or equal to 10% of the aggregate principal balance of the Mortgage Loans as of the Cut-off Date. In the event the Master Servicer does not exercise such right to purchase, the Servicer may exercise such right to purchase, subject to the conditions set forth in the Pooling and Servicing Agreement. In the event the Master Servicer or the Servicer (in each case, the “Terminator”) exercises its option, the purchase price payable in connection with the option will be equal to par with respect to the Mortgage Loans and the fair market value of all properties acquired by the trust in respect of any Mortgage Loans, plus accrued interest for each Mortgage Loan at the related Mortgage Rate to but not including the first day of the month in which the repurchase price is distributed, together with (to the extent not covered by the foregoing) all amounts due and owing to the Trustee, the Servicer, the Master Servicer, the Securities Administrator and the Swap Provider as of the termination date and pursuant to the Pooling and Servicing Agreement and the Interest Rate Swap Agreement. In the event the Terminator exercises this option, the portion of the purchase price allocable to the Class A Certificates and Mezzanine Certificates will be, to the extent of available funds, (i) 100% of the then outstanding Certificate Principal Balance of the Class A Certificates and Mezzanine Certificates, plus (ii) one month’s interest on the then outstanding Certificate Principal Balance of the Class A Certificates and Mezzanine Certificates at the then applicable Pass-Through Rate for each such class, plus (iii) any previously accrued but unpaid interest thereon to which the holders of the Class A Certificates and Mezzanine Certificates are entitled, together with the amount of any Net WAC Rate Carryover Amounts. The holders of the Residual Certificates shall pledge any amount received in a termination in excess of par to the holders of the Class CE Certificates. In no event will the trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the survivor of the persons named in the Pooling and Servicing Agreement. See “Description of the Securities-Termination” in the prospectus.

The Securities Administrator shall give notice of any termination to the Certificateholders, upon which the Certificateholders shall surrender their Certificates to the Securities Administrator for payment of the final distribution and cancellation. Such notice shall be given by letter, mailed not earlier than the 15th day and not later than the 25th day of the month next preceding the month of such final distribution, and shall specify (i) the Distribution Date upon which final payment of the Certificates will be made upon presentation and surrender of the Certificates at the office of the Securities Administrator therein designated, (ii) the amount of any such final payment and (iii) that the Record Date otherwise applicable to such Distribution Date is not applicable, payments being made only upon presentation and surrender of the Certificates at the office of the Securities Administrator therein specified.

In the event such notice is given in connection with the purchase of all of the Mortgage Loans by the Terminator, the Terminator shall deliver to the Securities Administrator for deposit in the Distribution Account not later than the Business Day prior to the Distribution Date on which the final distribution on the certificates an amount in immediately available funds equal to the above-described Termination Price. The Securities Administrator shall remit to the Servicer, the Master Servicer, the Trustee and the Custodians from such funds deposited in the Distribution Account (i) any amounts which the Servicer would be permitted to withdraw and retain from the Collection Account as if such funds had been deposited therein (including all unpaid Servicing Fees, Master Servicing Fees and all outstanding P&I Advances and Servicing Advances) and (ii) any other amounts otherwise payable by the Securities Administrator to the Master Servicer, the Trustee, the Custodians, the Servicer and the Swap Provider from amounts on deposit in the Distribution Account pursuant to the terms of the Pooling and Servicing Agreement prior to making any final distributions. Upon certification to the Trustee by the Securities Administrator of the making of such final deposit, the Trustee shall promptly release or cause to be released to the Terminator the Mortgage Files for the remaining Mortgage Loans, and Trustee shall execute all assignments, endorsements and other instruments delivered to it and necessary to effectuate such transfer.

167

Upon presentation of the Certificates by the Certificateholders on the final Distribution Date, the Securities Administrator shall distribute to each Certificateholder so presenting and surrendering its Certificates the amount otherwise distributable on such Distribution Date in respect of the Certificates so presented and surrendered. Any funds not distributed to any Holder or Holders of Certificates being retired on such Distribution Date because of the failure of such Holder or Holders to tender their Certificates shall, on such date, be set aside and held in trust and credited to the account of the appropriate non-tendering Holder or Holders. If any Certificates as to which notice has been given shall not have been surrendered for cancellation within six months after the time specified in such notice, the Securities Administrator shall mail a second notice to the remaining non-tendering Certificateholders to surrender their Certificates for cancellation in order to receive the final distribution with respect thereto. If within one year after the second notice all such Certificates shall not have been surrendered for cancellation, the Securities Administrator shall, directly or through an agent, mail a final notice to the remaining non-tendering Certificateholders concerning surrender of their Certificates. The costs and expenses of maintaining the funds in trust and of contacting such Certificateholders shall be paid out of the assets remaining in the trust funds. If within one (1) year after the final notice any such Certificates shall not have been surrendered for cancellation, the Securities Administrator shall pay to the Depositor all such amounts, and all rights of non-tendering Certificateholders in or to such amounts shall thereupon cease. No interest shall accrue or be payable to any Certificateholder on any amount held in trust by the Securities Administrator as a result of such Certificateholder’s failure to surrender its Certificate(s) on the final Distribution Date for final payment thereof. Any such amounts held in trust by the Securities Administrator shall be held uninvested in an Eligible Account.

In the event that the Terminator purchases all the Mortgage Loans and any properties acquired in respect thereof or the final payment on or other liquidation of the last Mortgage Loan, the Trust Fund shall be terminated in accordance with the following additional requirements:

(i) The Securities Administrator shall specify the first day in the 90-day liquidation period in a statement attached to each Trust REMIC’s final Tax Return pursuant to Treasury regulation Section 1.860F-1 and shall satisfy all requirements of a qualified liquidation under Section 860F of the Code and any regulations thereunder, as evidenced by an opinion of counsel obtained by and at the expense of the Terminator;

(ii) During such 90-day liquidation period and, at or prior to the time of making of the final payment on the Certificates, the Trustee shall sell all of the assets of REMIC I to the Terminator for cash; and

(iii) At the time of the making of the final payment on the Certificates, the Securities Administrator shall distribute or credit, or cause to be distributed or credited, to the Holders of the Residual Certificates all cash on hand in the Trust Fund (other than cash retained to meet claims), and the Trust Fund shall terminate at that time.

At the expense of the Terminator (or, if the Trust Fund is being terminated as a result of the Last Scheduled Distribution Date, at the expense of the Trust Fund), the Terminator shall prepare or cause to be prepared the documentation required in connection with the adoption of a plan of liquidation of each Trust REMIC.

168

By their acceptance of Certificates, the Holders thereof hereby agree to authorize the Securities Administrator to specify the 90-day liquidation period for each Trust REMIC, which authorization shall be binding upon all successor Certificateholders.

FEDERAL INCOME TAX CONSEQUENCES

In the opinion of Thacher Proffitt & Wood llp, counsel to the Depositor, assuming compliance with the provisions of the Pooling and Servicing Agreement, for federal income tax purposes, each of the REMICs established under the Pooling and Servicing Agreement will qualify as a REMIC under the Code.

For federal income tax purposes (i) the Residual Certificates will represent the “residual interests” in each REMIC elected by the trust and (ii) the Offered Certificates and the Class CE Certificates (exclusive of any right of the holder of such certificates to receive payments from or any obligation to make payments to the Reserve Fund in respect of Net WAC Rate Carryover Amounts or the Supplemental Interest Trust), and the Class P Certificates will represent the “regular interests” in, and will be treated as debt instruments of, a REMIC. See “Material Federal Income Tax Considerations-REMICs” in the prospectus.

For federal income tax purposes, certain classes of Offered Certificates may be treated as having been issued with original issue discount. The prepayment assumption that will be used in determining the rate of accrual of original issue discount, market discount and premium, if any, for federal income tax purposes will be based on the assumption that, subsequent to the date of any determination the adjustable-rate Mortgage Loans will prepay at a rate equal to 100% PPC (calculated based on the assumed prepayment rates set forth under “Yield on the Certificates—Weighted Average Lives” in this free writing prospectus) and the fixed-rate Mortgage Loans will prepay at a rate equal to 100% PPC calculated based on the assumed prepayment rates set forth under “Yield on the Certificates—Weighted Average Lives” in this free writing prospectus). No representation is made that the Mortgage Loans will prepay at that rate or at any other rate. See “Material Federal Income Tax Consideration-General” and “-REMICs-Taxation of Owners of Regular Securities” in the prospectus.

The holders of the Offered Certificates will be required to include in income interest on their certificates in accordance with the accrual method of accounting.

The Internal Revenue Service (the “IRS”) has issued original issue discount regulations (the “OID Regulations”) under sections 1271 to 1275 of the Code that address the treatment of debt instruments issued with original issue discount, Purchasers of the Offered Certificates should be aware that the OID Regulations do not adequately address certain issues relevant to, or are not applicable to, prepayable securities such as the Offered Certificates. In addition, there is considerable uncertainty concerning the application of the OID Regulations to REMIC Regular Certificates that provide for payments based on an adjustable rate such as the Offered Certificates. Because of the uncertainty concerning the application of Section 1272(a)(6) of the Code to such certificates and because the rules of the OID Regulations relating to debt instruments having an adjustable rate of interest are limited in their application in ways that could preclude their application to such certificates even in the absence of Section 1272(a)(6) of the Code, the IRS could assert that the Offered Certificates should be treated as issued with original issue discount or should be governed by the rules applicable to debt instruments having contingent payments or by some other method not yet set forth in regulations. Prospective purchasers of the Offered Certificates are advised to consult their tax advisors concerning the tax treatment of such certificates.

169

In certain circumstances the OID Regulations permit the holder of a debt instrument to recognize original issue discount under a method that differs from that used by the issuer. Accordingly, the holder of an Offered Certificate may be able to select a method for recognizing original issue discount that differs from that used by the Trust in preparing reports to the certificateholders and the IRS.

If the method for computing original issue discount described above results in a negative amount for any period with respect to a Certificateholder, the amount of original issue discount allocable to that period would be zero and the Certificateholder will be permitted to offset that negative amount only against future original issue discount, if any, attributable to those Certificates.

Certain of the certificates may be treated for federal income tax purposes as having been issued at a premium. Whether any holder of a certificate will be treated as holding such certificate with amortizable bond premium will depend on such certificateholders purchase price and the distributions remaining to be made on such certificate at the time of its acquisition by such certificateholder. Holders of such certificates should consult their own tax advisors regarding the possibility of making an election to amortize such premium. See “Material Federal Income Tax Considerations- REMICs—Taxation of Owners of Regular Securities” in the Prospectus.

Each holder of an Offered Certificate is deemed to own an undivided beneficial ownership interest in a REMIC regular interest and the right to receive payments from either the Reserve Fund or the Supplemental Interest Trust in respect of any Net WAC Rate Carryover Amount or the obligation to make payments to the Supplemental Interest Trust. The Reserve Fund, the Interest Rate Swap Agreement and the Supplemental Interest Trust are not assets of any REMIC. The REMIC regular interest corresponding to an Offered Certificate will be entitled to receive interest and principal payments at the times and in the amounts equal to those made on the certificate to which it corresponds, except that (i) the maximum interest rate of that REMIC regular interest will equal the Net WAC Pass-Through Rate computed for this purpose by limiting the Swap Notional Amount of the Interest Rate Swap Agreement to the aggregate principal balance of the Mortgage Loans and (ii) any Swap Termination Payment will be treated as being payable solely from Net Monthly Excess Cashflow. As a result of the foregoing, the amount of distributions on the REMIC regular interest corresponding to an Offered Certificate may exceed the actual amount of distributions on the Offered Certificate.

170

Any payments made to a beneficial owner of an Offered Certificate in excess of the amounts payable on the corresponding REMIC regular interest will be treated as having been received as a payment on a notional principal contract. To the extent the sum of such periodic payments for any year exceeds that year’s amortized cost of any Net WAC Rate Carryover Amount, such excess represents net income for that year. Conversely, to the extent that the amount of that year’s amortized cost exceeds the sum of the periodic payments, such excess will represent a net deduction for that year. In addition, any amounts payable on such REMIC regular interest in excess of the amount of payments on the Offered Certificate to which it relates will be treated as having been received by the beneficial owners of such Certificates and then paid by such owners to the Supplemental Interest Trust pursuant to the Interest Rate Swap Agreement, and such excess should be treated as a periodic payment on a notional principal contract that is made by the beneficial owner during the applicable taxable year and that is taken into account in determining the beneficial owner’s net income or net deduction with respect to any Net WAC Rate Carryover Amount for such taxable year. Although not clear, net income or a net deduction with respect to any Net WAC Rate Carryover Amount should be treated as ordinary income or as an ordinary deduction. Holders of the Offered Certificates are advised to consult their own tax advisors regarding the tax characterization and timing issues relating to a Swap Termination Payment.

Because a beneficial owner of any Net WAC Rate Carryover Amount will be required to include in income the amount deemed to have been paid by such owner, but may not be able to deduct that amount from income, a beneficial owner of an Offered Certificate may have income that exceeds cash distributions on the Offered Certificate, in any period and over the term of the Offered Certificate. As a result, the Offered Certificates may not be a suitable investment for any taxpayer whose net deduction with respect to any Net WAC Rate Carryover Amount would be subject to the limitations described above.

Upon the sale of an Offered Certificate, the amount of the sale allocated to the selling certificateholder’s right to receive payments from the Reserve Fund and the Supplemental Interest Trust in respect of any Net WAC Rate Carryover Amount would be considered a “termination payment” under the Notional Principal Contract Regulations allocable to the related Offered Certificate, as the case may be. A holder of an Offered Certificate will have gain or loss from such a termination of the right to receive payments from the Reserve Fund and the Supplemental Interest Trust in respect of any Net WAC Rate Carryover Amount equal to (i) any termination payment it received or is deemed to have received minus (ii) the unamortized portion of any amount paid (or deemed paid) by the certificateholder upon entering into or acquiring its interest in the right to receive payments from the Reserve Fund and the Supplemental Interest Trust in respect of any Net WAC Rate Carryover Amount.

Gain or loss realized upon the termination of the right to receive payments from the Reserve Fund and the Supplemental Interest Trust in respect of any Net WAC Rate Carryover Amount will generally be treated as capital gain or loss. Moreover, in the case of a bank or thrift institution, Code Section 582(c) would likely not apply to treat such gain or loss as ordinary.

171

It is possible that the right to receive payments in respect of any Net WAC Rate Carryover Amount could be treated as a partnership among the holders of all of the Certificates, in which case holders of such Certificates potentially would be subject to different timing of income and foreign holders of such Certificates could be subject to withholding in respect of any related Net WAC Rate Carryover Amount. Holders of the Offered Certificates are advised to consult their own tax advisors regarding the allocation of issue price, timing, character and source of income and deductions resulting from the ownership of their Certificates.

The REMIC regular interest component of each Offered Certificate will be treated as assets described in Section 7701(a)(19)(C) of the Code, and as “real estate assets” under Section 856(c)(5)(B) of the Code, generally, in the same proportion that the assets of the Trust, exclusive of the assets not included in any REMIC, would be so treated. In addition, the interest derived from the REMIC regular interest component of each Offered Certificate will be interest on obligations secured by interests in real property for purposes of section 856(c)(3) of the Code, subject to the same limitation in the preceding sentence. The Notional Principal Contract component of each Regular Certificate will not qualify, however, as an asset described in Section 7701(a)(19)(C) of the Code, as a real estate asset under Section 856(c)(5)(B) of the Code or as a “qualified mortgage” within the meaning of Section 860G(a)(3) of the Code. As a result, the Offered Certificates generally may not be a suitable investment for a REMIC, a real estate investment trust or an entity intending to qualify under Section 7701(a)(19)(C) of the Code.

Because any Net WAC Rate Carryover Amount is treated as separate rights of the Offered Certificates not payable by any REMIC elected by the Trust, such rights will not be treated as qualifying assets for any certificateholder that is a mutual savings bank, domestic building and loan association, real estate investment trust, or REMIC. In addition, any amounts received from the Reserve Fund and the Supplemental Interest Trust will not be qualifying real estate income for real estate investment trusts or qualifying income for REMICs.
