the various parties involved in the transaction and their functions.

[fwp002.jpg]

What You Own

Your certificates represent interests in certain assets of the trust fund only. All payments to you will come only from the amounts received in connection with those assets.

The trust fund contains a pool of mortgage loans and certain other assets, as described under "The Trust Fund" in this term sheet supplement.

Information About the Mortgage Pool

The mortgage pool will consist of conventional fixed-rate residential mortgage loans. All of the mortgage loans are secured by residential properties. The mortgage pool will consist of up to three loan groups (each, a "Loan Group"), each of which will consist of separate loan subgroups (each, a "Subgroup") that contain mortgage loans bearing interest within a specific range of Net Rates.

The scheduled principal balance of each mortgage loan in each Loan Group will be allocated, based on such mortgage loan's Net Rate, either (i) to one Collateral Group only or (ii) between two Collateral Groups, based on a fixed fraction which differs among mortgage loans (in each case, the "Applicable Fraction"). Each "Collateral Group" is a total dollar amount of principal of mortgage loans consisting of differing percentages of the interest on, and principal of, particular mortgage loans, calculated so that the principal and interest due on each mortgage loan is treated as if that mortgage loan were two mortgage loans bearing interest at two different effective Net Rates (each such rate an "Effective Net Rate"), one higher than and one lower than the original Net Rate of the mortgage loan. The "Net Rate" of a mortgage loan is its mortgage interest rate minus the servicing fee rate and the rate on any lender-paid primary mortgage insurance for that mortgage loan. This allocation enables the issuing entity to treat each Loan Group as if it were made up of Collateral Groups bearing interest at various fixed rates. This allocation will affect the rate of distributions on your certificates, because principal payments collected on each mortgage loan in each Loan Group will be allocated to the related Collateral Groups and used for distributions on one or more classes of certificates related to those Collateral Groups. For further detail on the calculation of the Applicable Fractions applied to each mortgage loan in each Loan Group, see the prospectus supplement and "Description of the Certificates—Glossary of Definitions Relating to the Priority of Distributions" in this term sheet supplement.

The Offered Certificates

The classes of certificates in the term sheet with an "A" in their class designations are referred to in this term sheet supplement as the "Senior Certificates" or the "Class A Certificates". Each class of Senior Certificates will relate to a specified Collateral Group. In naming the classes of Senior Certificates (other than any Class A-P and Class A-X Certificates), the first numeral (such as "1," "2," "3" and so forth), if any, refers to the Collateral Group. In addition, the first letter ("A") refers to the status of the class as senior and the final character refers to the subclass. For example, the "Class 1A Certificates" refers to all of the classes of Senior Certificates related to Collateral Group 1, the "Class 2A Certificates" refers to all of the classes of Senior Certificates related to Collateral Group 2 and so forth. Subject to certain crossovers following the occurrence of delinquencies and losses on the mortgage loans, principal on the classes of certificates related to a Collateral Group will be paid solely from the mortgage loans or portions thereof allocated to that Collateral Group based on the Applicable Fractions for each of those mortgage loans.

The Senior Certificates may also include one or more classes of ratio strip principal only certificates (the "Class A-P Certificates") and one or more classes of ratio strip interest only certificates (the "Class A-X Certificates"). Each class of Class A-P Certificates will receive principal distributions only from the related Discount Loans (as defined herein). Each class of Class A-X Certificates will receive interest distributions only from the related Premium Loans (as defined herein) at the applicable Certificate interest rate.

Each class of Class A-P Certificates will be entitled to a portion of principal payments on each mortgage loan in one or more related Loan Groups that has a Net Rate less than the designated rate of the related Collateral Group in one or more of those Loan Groups with the lowest fixed interest rate. The Class A-P Certificates will be "principal only" certificates and will not be entitled to any interest.

The Class A-X Certificates will be entitled to interest on the mortgage loans in one or more related Loan Groups to the extent that interest on such mortgage loans accrues at a Net Rate in excess of the designated rate of the Collateral Group in one or more of those Loan Groups with the highest fixed interest rate. The A-X Certificates will be "interest only" certificates and will not be entitled to distributions of principal.

The classes of certificates set forth in the term sheet as "exchangeable securities" are collectively referred to in this term sheet supplement as "Exchangeable Securities".

See "Description of the Certificates ─ Exchangeable Certificates" in this term sheet supplement.

The classes of certificates in the term sheet with a "B" or an "M" in their class designations are referred to in this term sheet supplement as the "Subordinate Certificates." The Trust Fund may issue two separate groups of Subordinate Certificates, which may consist of (x) the Class 1M-1, Class 1B-1, Class 1B-2, Class 1B-3, Class 1B-4, Class 1B-5 and Class 1B-6 Certificates and (y) the Class 2M-1, Class 2B-1, Class 2B-2, Class 2B-3, Class 2B-4, Class 2B-5 and Class 2B-6 Certificates. Each of these groups of Subordinate Certificates will relate to all of the mortgage loans in one or more separate related Loan Groups and distributions on each group of Subordinate Certificates will be paid solely from the mortgage loans in the related Loan Groups.

The Class 1M-1, Class 1B-1, Class 1B-2, Class 1B-3, Class 2M-1, Class 2B-1, Class 2B-2 and Class 2B- 3 Certificates are collectively referred to in this term sheet supplement as the "Senior Subordinate Certificates."

The Other Certificates

Any subordinate certificates issued by the trust without an investment grade rating will not be offered by the term sheet, this term sheet supplement or the prospectus supplement. Generally, the Class 1B-4, Class 1B-5, Class 1B-6, Class 2B-4, Class 2B-5 and Class 2B-6 Certificates (collectively, the "Junior Subordinate Certificates" may be privately offered, are subordinated to the related classes of offered certificates and provide credit enhancement for the related classes of offered certificates. See "Description of the Certificates—Subordination and Allocation of Losses" in this term sheet supplement.

The Class X Certificate, if any, represents the right to receive certain amounts on deposit in any basis risk reserve fund as described in this term sheet supplement.

The classes of certificates in the term sheet with an "R" in their class designation are referred to in this term sheet supplement as the "Residual Certificates."

Only the Senior Certificates and the Senior Subordinate Certificates will be offered by this term sheet supplement and the term sheet.

The certificates will represent interests in the mortgage pool described below.

Structural Overview

The following chart illustrates generally the distribution priorities and the subordination features applicable to the offered certificates.

[fwp004.jpg]

Closing Date

On or about February 24, 2006.

Cut-off Date

February 1, 2006.

Distribution Dates

The 25th day of each month, or if the 25th day is not a Business Day, on the next succeeding Business Day. The first distribution date will be March 27, 2006.

"Business Day" for the purposes of distribution dates and the master servicing and trust agreement means any day other than (i) a Saturday or Sunday or (ii) a legal holiday or banking holiday in the State of New York or any state in which the principal offices of Goldman Sachs Mortgage Company, the master servicer, the securities administrator or the trustee are located (for purposes of the master servicing and trust agreement) or any state in which the principal offices of Goldman Sachs Mortgage Company or the applicable servicer, or any assignee of any such party, are located (for purposes of any of the servicing agreements).

Monthly Distributions

Each month the securities administrator, on behalf of the trustee, will make distributions of interest and principal to the holders of the certificates.

Rated Final Distribution Date

The rated final Distribution Date for distributions on each class of offered certificates will be the Distribution Date in the month immediately following the month in which the maturity date of the latest maturing mortgage loan related to such certificates occurs.

Record Date

The record date for the offered certificates and each distribution date will be the last Business Day of the related interest accrual period.

Certificate Interest Rates

The certificate rates for the offered certificates will equal the rates described in the footnotes on the table on the cover of the prospectus supplement and as set forth or described in the term sheet.

Interest Accrual Period

For any Distribution Date, the interest accrual period (i) for each class of offered certificates other than any class of certificates that accrues interest based on LIBOR (each a "LIBOR Certificate") the immediately preceding calendar month and (ii) for the LIBOR Certificates, the period from and including the 25^th day of the immediately preceding month to and including the 24^th day of the current month.

The interest to be distributed to each class of certificates entitled thereto on each Distribution Date will be calculated by multiplying (i) 1/12 of the per annum applicable certificate interest rate (the certificate interest rate) set forth or described in the term sheet by (ii) the class principal balance or Notional Amount, as applicable, of such class at the close of business on the preceding Distribution Date. For the first Distribution Date, interest on all classes of certificates entitled to interest (other than the LIBOR Certificates) will accrue from February 1, 2006. For the first Distribution Date, interest on the LIBOR Certificates will accrue from February 25, 2006.

Distributions of Interest

On each Distribution Date, interest on the certificates related to each Collateral Group will be distributed from related collections and Advances (as defined below) in the order described in the prospectus supplement and "Description of the Certificates—Priority of Distributions" in this term sheet supplement. Interest to be distributed to each class of certificates entitled thereto on any Distribution Date will consist of (i) previously accrued interest that remained unpaid on the previous Distribution Date and (ii) interest accrued for the related interest accrual period (together, the "Accrued Certificate Interest") on the class principal balance or Notional Amount, as applicable, of such class. Interest will not accrue on overdue interest.

On each Distribution Date, Accrued Certificate Interest will not be distributed to any Z Certificates (as described below) but will be added to their respective class principal balances and distributed as described in this term sheet supplement.

It is possible that, on a Distribution Date, collections from the mortgage loans will not be sufficient to make the interest distributions contemplated in this term sheet supplement. If a servicer does not make an otherwise required Advance in respect of a related mortgage loan because it determines that the Advance would be nonrecoverable, some certificates, most likely the related Subordinate Certificates, may not receive the full amount of Accrued Certificate Interest to which they are entitled. Such amounts will be paid on future Distribution Dates, if funds become available, without additional interest.

Compensating Interest and Interest Shortfalls

When mortgagors make full or partial prepayments, they need not pay a full month's interest. Instead, they are required to pay interest only to the date of the prepayment. Under the terms of each servicing agreement, on any Distribution Date, the applicable servicer has agreed to pay compensating interest in an amount equal to the lesser of (x) the amount required to cause the securities administrator (on behalf of the certificateholders) to receive a full month's interest on any voluntary principal prepayments in full (and with respect to certain servicers, any voluntary principal prepayments in part) received by that servicer during the due period beginning on the second day of the month immediately preceding the month in which that Distribution Date occurs and ending on the first day of the month in which that Distribution Date occurs and (y) one-half of the applicable servicing fee for that Distribution Date. In the event the related servicer does not pay such compensating interest on that Distribution Date, the master servicer is required to pay such amount (to the extent that such amount does not exceed the total of its master servicing fee for that Distribution Date) through a reduction in the amount of the master servicing fee. Neither the servicers nor any successor servicer will pay compensating interest for any shortfalls resulting from the application of the Servicemembers Civil Relief Act, as amended, or any comparable state or local statute. As a result, interest shortfalls on the certificates may occur. For a description of how compensating interest is allocated among the certificates as well as important limitations on the amount of compensating interest that will be allocated among the certificates, see "Yield and Prepayment Considerations—Principal Prepayments and Compensating Interest" in this term sheet supplement.

Interest Rate Caps

The holders of certain classes of certificates may have the benefit of one or more interest rate cap agreements entered into with an interest rate cap provider to be set forth in the prospectus supplement. Any payments received under any interest rate cap agreement with respect to any Distribution Date will be available to cover basis risk shortfalls in interest payable to the holders of the related class or classes of certificates when the related interest rate is limited by the applicable maximum rate. Payments under each interest rate cap agreement to the holders of the related certificates may mitigate against the effects of a mismatch between the Effective Net Rate on the mortgage loans contributing to the related Collateral Group and one-month LIBOR used to determine the interest rates on these certificates.

Distributions of Principal

General

As principal is collected on the mortgage loans in each Loan Group, that principal will be allocated among the related classes of certificates based on the priorities and formulas described herein. In general, payments on the Senior Certificates will be made from collections on the mortgage loans contributing to the related Collateral Group. Distributions on the Subordinate Certificates will be made from all of the Collateral Groups in one or more related Loan Groups.

Principal collected on the mortgage loans in each Loan Group will either be allocated entirely to one Collateral Group or split between two Collateral Groups based on the Applicable Fractions of that mortgage loan for those Collateral Groups. Except to the extent that collections otherwise payable to the related Subordinate Certificates are used to make payments to Senior Certificates related to other Collateral Groups, all principal collections allocated to a particular Collateral Group will be distributed to the holders of certificates related to that Collateral Group. Not every class of certificates entitled to principal, however, will receive principal on each Distribution Date.

Principal collections will be further divided between the related Senior Certificates and the related Subordinate Certificates in the manner described herein.

The Senior Certificates may include one or more classes of planned amortization certificates ("PACs") or targeted amortization certificates ("TACs"). Principal collections on PACs and TACs will be allocated in a manner that, to the extent possible, will result in the certificates of such class or classes receiving principal payments according to a schedule. The receipt by a certificateholder of payments that match the related schedule will depend, however, on the rate at which payments are collected on the related mortgage loans and there is no assurance that the schedule will be maintained. The amounts and priority of distributions to the certificates are further described in "Description of the Certificates—Priority of Distributions" and "—Distributions of Principal on the Certificates" in this term sheet supplement.

The Senior Certificates may include one or more classes of super senior certificates ("Super Senior Certificates") and one or more classes of related credit support certificates ("Credit Support Certificates"). Losses otherwise allocable to any Super Senior Certificates will instead be allocated to the related class or classes of Credit Support Certificates, until the class principal balances thereof have been reduced to zero.

The Senior Certificates may include one or more classes of non-accelerating senior certificates ("NAS Certificates"). NAS Certificates will not necessarily benefit from the accelerated distributions available to the other classes of senior certificates.

The Senior Certificates may include one or more classes of senior support certificates ("Senior Support Certificates"). Any Senior Support Certificates will provide support for the related classes of PACs, TACs or NAS Certificates.

The Senior Certificates may include one or more classes of accrual certificates ("Z Certificates"). Interest distributions on any Z Certificates will not be distributed on these certificates but will instead be added to the class principal balance thereof and distributed to the related class or classes accretion directed certificates ("AD Certificates"), until the class principal balance of those AD Certificates has been reduced to zero.

The Subordinate Certificates will generally receive distributions of principal in the order of seniority of such certificates, as described in the term sheet and in "Description of the Certificates—Priority of Distributions" and "—Subordination and Allocation of Losses" in this term sheet supplement. Each class of Subordinate Certificates will be entitled, subject to the priority of distributions and subordination rules, to receive a portion of the scheduled principal collections on the related mortgage loans on each Distribution Date but will not be entitled to receive any share of principal prepayments prior to the Distribution Date in March 2011.

Interest Only Certificates

The Class A-X Certificates are, and other classes of certificates may be, "Interest Only Certificates." This means that investors in these classes of certificates will receive distributions of interest based on the related Notional Amount, but will not receive distributions of principal.

The notional amount for each class of Class A-X Certificates on each Distribution Date will be equal to the total principal balance of the mortgage loans in each related Loan Group having Net Rates greater than or equal to the certificate interest rate on the Class A-X Certificates (the "Premium Loans") multiplied by the following fraction:

weighted average Net Rate of all related

Premium Loans in that Loan Group minus the designated

rate for the applicable Collateral Group

the certificate interest rate on that class of

Class A-X Certificates.

Principal Only Certificates

The Class A-P Certificates are, and other classes of senior certificates may be, "Principal Only Certificates." This means that the investors in a class of Class A-P Certificates will not receive distributions of interest.

The securities administrator will distribute a portion of the principal payments received on each mortgage loan in each related Loan Group that has a Net Rate less than the designated rate for the applicable Collateral Group (the "Discount Loans") to investors in the related class of Class A-P Certificates.

This portion is determined for each Loan Group based on the following fraction as to each related Discount Loan in that Loan Group:

the designated rate for the applicable Collateral Group minus the
Net Rate of such Discount Loan in

that Loan Group
the designated rate for the applicable Collateral Group.

Priority of Principal Distributions

It is possible that, on any particular Distribution Date, payments from the mortgage loans and P&I Advances will be insufficient to make principal distributions as contemplated in this term sheet supplement. As a result, some related certificates, most likely the related Subordinate Certificates (and among the related Subordinate Certificates, the most junior class then outstanding), may not receive the full amount of principal distributions to which they are entitled.

The calculation of the amount of principal and interest that the securities administrator will distribute on each Distribution Date is very complex. For a more detailed description of how distributions of principal will be allocated among the various classes of certificates, see the term sheet and "Description of the Certificates—Priority of Distributions" and "—Distributions of Principal on the Certificates" in this term sheet supplement.

Exchangeable Certificates

On each Distribution Date when Exchangeable Certificates are outstanding, principal distributions from the applicable related certificates are allocated to the related Exchangeable Certificates that are entitled to principal. The payment characteristics of the classes of Exchangeable Certificates will reflect the payment characteristics of their related classes of regular certificates.

See "Description of the Certificates—Exchangeable Certificates—Procedures" in this term sheet supplement and "Description of the Securities—Exchangeable Securities" in the prospectus for a description of Exchangeable Certificates and exchange procedures and fees.

Credit Enhancements

Subordination

If on any Distribution Date there is a shortfall in the funds needed to make all payments to holders of certificates related to any Collateral Group, the related Senior Certificates will receive distributions of interest and principal, as applicable, before the related Subordinate Certificates are entitled to receive distributions of interest or principal. The related Subordinate Certificates will receive distributions of their pro rata shares of the principal distribution amount from that Collateral Group allocated to those Subordinate Certificates in their order of seniority. This provides additional security to the related Senior Certificates. In a similar fashion, each class of Subordinate Certificates will provide credit enhancement to all other classes of related Subordinate Certificates with lower numerical class designations.

Shifting Interests

The Senior Certificates (other than the Interest Only Certificates and the Class A-P Certificates) will, in the aggregate, generally receive their pro rata share of all scheduled principal payments and 100% of all principal prepayments from mortgage loans or portions of mortgage loans in the related Collateral Groups until the 5th anniversary of the first Distribution Date. Thereafter, the Senior Certificates (other than the Interest Only Certificates and the Class A-P Certificates) related to such groups will, in the aggregate, generally receive their pro rata share of scheduled principal payments and a disproportionately large, but decreasing, share of principal prepayments from the mortgage loans in such groups (subject to certain triggers that would reduce distributions to the related Subordinate Certificates). This will result in a faster rate of return of principal to the Senior Certificates (other than the Interest Only Certificates and the Class A-P Certificates) than would occur if the Senior Certificates and the Subordinate Certificates received all payments from the related Collateral Groups, including prepayments, pro rata, and increases the likelihood that holders of Senior Certificates (other than the Class A-P Certificates) will receive the full amount of principal to which they are entitled. The NAS Certificates will not necessarily benefit from this accelerated repayment.

If the subordination level for any class of Subordinate Certificates on any Distribution Date is less than the initial subordination level on the Closing Date for that class of Subordinate Certificates the most senior class of related Subordinate Certificates that has not maintained its initial subordination level and each class of related Subordinate Certificates senior thereto will receive pro rata distributions from principal prepayments otherwise distributable to more junior classes of related Subordinate Certificates. For a more detailed description of how principal prepayments are allocated among the Senior Certificates and the related Subordinate Certificates, see the prospectus supplement and "Description of the Certificates—Priority of Distributions" and the related definitions under "Description of the Certificates—Glossary of Definitions Relating to the Priority of Distributions" in this term sheet supplement.

Allocation of Losses

Realized Losses

A loss is realized on a mortgage loan when the applicable servicer determines that it has received all amounts that it expects to recover from that mortgage loan and the amounts are less than the outstanding principal balance of that mortgage loan, plus its accrued and unpaid interest and any related expenses, such as taxes or insurance premiums previously advanced by that servicer, and expenses of foreclosure (but not including any Subsequent Recoveries as described in this term sheet supplement). In general, losses will be borne by the most junior class of related Subordinate Certificates then outstanding.

Because the Subordinate Certificates represent interests in all of the Collateral Groups in one or more related Loan Groups (other than the Collateral Group or Collateral Groups related to the Class A-P Certificates), the principal balances of the Subordinate Certificates could be reduced to zero as a result of disproportionately high losses on the mortgage loans contributing to any related Collateral Group, increasing the likelihood that losses experienced in the other related Collateral Groups will be allocated to the Senior Certificates corresponding to those Collateral Groups.

If the principal balances of all of the related Subordinate Certificates have been reduced to zero, further losses on the related mortgage loans (other than the portion of those losses allocable to the Class A-P Certificates) will be allocated to the related classes of Senior Certificates (other than the related Interest Only Certificates), pro rata based on their outstanding class principal balances, until the total class principal balance of such classes of certificates has been reduced to zero; provided, that losses otherwise allocable to Super Senior Certificates will instead be allocated to the related class or classes of Credit Support Certificates, until the class principal balances thereof have been reduced to zero. The Applicable Fraction of each loss on a Discount Loan will be allocated to the related class of Class A-P Certificates.

Cross-Collateralization

Under certain limited circumstances, payments on the mortgage loans contributing to one Collateral Group may be distributed to holders of certain Senior Certificates corresponding to the other related Collateral Groups. As described in greater detail in this term sheet supplement, this "cross-collateralization" among the related Collateral Groups may occur in two basic ways. For example:

Rapid prepayment situations:

If the Senior Certificates relating to one Collateral Group in a Loan Group have been retired, and the related mortgage loans are performing below certain standards, then certain payments on the mortgage loans relating to the retired Senior Certificates will be paid to the remaining Senior Certificates of the other Collateral Groups in that Loan Group and any other related Loan Groups, if any, before being paid to the related Subordinate Certificates.

High loss situations:

If the total principal amount of the Senior Certificates relating to one Collateral Group in a Loan Group is greater than the total principal balance of the applicable portions of the related mortgage loans, then certain payments on the mortgage loans in the other Collateral Groups in that Loan Group and any other related Loan Groups otherwise payable to the related Subordinate Certificates will be paid to those Senior Certificates.

See "Description of the Certificates—Cross-Collateralization" in this term sheet supplement.

Servicing of the Mortgage Loans

It is possible that the servicing of certain of the mortgage loans will be transferred in the future to one or more servicers other than the initial servicers in accordance with the provisions of the master servicing and trust agreement and the related servicing agreement, either because, with respect to the mortgage loans acquired through Goldman Sachs Mortgage Company’s mortgage conduit program, the party that owns the related servicing rights (which is currently Goldman Sachs Mortgage Company) elects to effect such a transfer or, with respect to all of the mortgage loans, as a result of the occurrence of unremedied events of default in servicer performance under the related servicing agreement. See "The Servicers" in this term sheet supplement.

The master servicer may perform certain of the functions and services of a successor servicer, which are enumerated in this term sheet supplement and in the prospectus.

Source of Payments

The mortgagors are obligated to make monthly scheduled payments of principal and interest to the servicers. On the 18th day of each month, or if such day is not a Business Day, on the immediately preceding or next succeeding Business Day, as specified in the applicable servicing agreement, (the "Servicer Remittance Date"), the servicers will remit the Available Distribution Amount to the master servicer, and two Business Days prior to the Distribution Date (the "Master Servicer Remittance Date"), the master servicer will remit the Available Distribution Amount to the securities administrator. Upon receipt, the securities administrator is required to deposit funds received from the master servicer into a trust account established by the securities administrator for the benefit of the certificateholders (the "Certificate Account") from which the securities administrator will make distributions to the certificateholders on each Distribution Date.

Advances

If a servicer receives a payment on a mortgage loan that is less than the full scheduled payment due, that servicer will advance its own funds to cover the shortfall (a "P&I Advance"). In addition, each servicer will be required to advance certain amounts necessary to protect the value of each mortgage loan that it services, such as property taxes and insurance premiums, if the applicable mortgagor does not pay such amounts (such amounts, "Servicing Advances" and, together with P&I Advances, "Advances"). Each servicer will be entitled to reimbursement of such amounts in all cases, even if such reimbursement ultimately results in a shortfall to one or more classes of certificateholders. Further, no servicer will be required to make an Advance if it concludes that such Advance will not be recoverable from future payments or collections on that mortgage loan. See "Description of the Certificates—Advances" in this term sheet supplement.

Fees of the Master Servicer, Securities Administrator, Trustee and Servicers

As compensation for its services as master servicer, Wells Fargo Bank, N.A. will be entitled to receive the interest or investment income, or a portion thereof, earned by it on amounts deposited in, or credited to, the master servicer account. The remainder of any interest or investment income earned on such amounts deposited in, or credited to, the master servicer account will not be available for distribution to certificateholders. In the event the master servicer assumes the duties of a servicer under any sale and servicing agreement, it shall be entitled to receive as compensation the servicer fees and other compensation that would have been payable to the servicer under that sale and servicing agreement.

The securities administrator will receive, as compensation for its services, a portion of the interest or investment income earned by it on amounts deposited in, or credited to, the certificate account, after payment of the trustee fee.

The trustee is entitled to an annual trustee fee, which will be paid by the securities administrator from investment earnings on amounts on deposit in the certificate account. The trustee fee will be an amount equal to $4,250.

Each servicer is entitled with respect to each mortgage loan serviced by it to a monthly servicing fee, which will be retained by that servicer from that mortgage loan or payable monthly from amounts on deposit in the collection account. The servicing fee for each mortgage loan will be an amount equal to interest at one twelfth of a rate equal to approximately 0.20% to 0.25% on the stated principal balance of that mortgage loan.

Required Repurchases of Mortgage Loans

If with respect to any mortgage loan any of the representations and warranties made by the related originator are breached in any material respect as of the date made, or there exists any uncured material document defect, the related originator will be obligated to repurchase the mortgage loan as further described in this term sheet supplement under "Description of the Certificates—Transfer of the Mortgage Loans to the Trustee" and "—Representations and Warranties Regarding the Mortgage Loans."

Optional Purchase of the Mortgage Loans

On any Distribution Date when the aggregate outstanding principal balance of the mortgage loans in a Loan Group or in related Loan Groups is less than 1% of the aggregate scheduled principal balance of the mortgage loans in that Loan Group or Loan Groups as of the cut-off date, the master servicer may purchase from the trust fund all remaining mortgage loans in that Loan Group or Loan Groups and all property acquired in respect of any such mortgage loan remaining in the trust fund. If these mortgage loans and any related property are purchased, the proceeds of such sale will be distributable to the related outstanding classes of certificates in retirement thereof, up to an amount equal to the aggregate outstanding class principal balance thereof (if applicable) plus accrued interest (excluding the amount of any basis risk shortfalls).

Denominations

The Class A Certificates (other than the Principal Only Certificates and the Interest Only Certificates) are offered in minimum denominations of $25,000 initial principal balance each and multiples of $1 in excess of $25,000. With respect to initial European investors only, the underwriter will only sell offered certificates in minimum total investment amounts of $100,000. The Senior Subordinate Certificates are offered in minimum denominations of $250,000 initial principal balance each and multiples of $1 in excess of $250,000. Any Interest Only Certificates (other than the Class A-X Certificates) are offered in minimum denominations of $1,000,000 initial Notional Amount each and multiples of $1 in excess of $1,000,000. Each class of Class A-P and Class A-X Certificates are each offered in the form of a single Certificate representing the entire initial class principal balance or notional amount thereof, as applicable.

Legal Investment

As of the date of their issuance, the Senior Certificates and any other classes of certificates rated in one of the top two rating categories by at one least one of Standard & Poor’s Ratings Group, a division of The McGraw-Hill Companies, Inc., Moody’s Investors Service, Inc. and Fitch Ratings will be "mortgage related securities" for purposes of the Secondary Mortgage Market Enhancement Act of 1984, as amended. See "Certain Legal Investment Aspects" in this term sheet supplement for important information concerning possible restrictions on ownership of the offered certificates by regulated institutions. You are encouraged to consult your own legal advisors in determining whether and to what extent the offered certificates constitute legal investments for you.

ERISA Considerations

Subject to important considerations described under "ERISA Considerations" in this term sheet supplement and in the prospectus, it is expected that the Senior Certificates and the Senior Subordinate Certificates will be eligible for purchase by persons investing assets of employee benefit plans or individual retirement accounts. See "ERISA Considerations" in this term sheet supplement and in the prospectus.

Federal Income Tax Consequences

For federal income tax purposes, the securities administrator will elect to treat all or a portion of the trust fund as one or more REMICs. The offered certificates will represent one or more regular interests (exclusive of any right to receive basis risk shortfalls) and will generally be treated as debt for federal income tax purposes. For federal income tax purposes, the Residual Certificates will represent ownership of the residual interest in each REMIC. Any Interest Only Certificates, Principal Only Certificates and Accrual Certificates will, and other classes of certificates may, be issued with original issue discount ("OID") for federal income tax purposes.

For further information regarding the federal income tax consequences of investing in the offered certificates, see "Certain Federal Income Tax Consequences" in this term sheet supplement and "Federal Income Tax Consequences" in the prospectus.

Ratings

The offered certificates are required to receive the ratings from one or more of Standard & Poor’s Ratings Group, a division of The McGraw-Hill Companies, Inc., Moody’s Investors Service, Inc. and Fitch Ratings indicated in the term sheet. The ratings on the offered certificates address the likelihood of the receipt by holders of the offered certificates of all distributions on the underlying mortgage loans to which they are entitled. The ratings do not address the likely actual rate of prepayments on the mortgage loans. The rate of prepayments on the mortgage loans, if different than originally anticipated, could adversely affect the yield realized by holders of the offered certificates or cause the holders of the offered certificates entitled to interest only to fail to recover their initial investments.

The ratings on the certificates do not represent an assessment of the likelihood of the distribution of any basis risk shortfalls.

A security rating is not a recommendation to buy, sell or hold securities. Ratings may be lowered, withdrawn or qualified at any time by any of the rating agencies.

RISK FACTORS

THE OFFERED CERTIFICATES ARE NOT SUITABLE INVESTMENTS FOR ALL INVESTORS. IN PARTICULAR, PROSPECTIVE INVESTORS SHOULD NOT PURCHASE ANY CLASS OF OFFERED CERTIFICATES UNLESS THEY UNDERSTAND AND ARE ABLE TO BEAR THE PREPAYMENT, CREDIT, LIQUIDITY AND MARKET RISKS ASSOCIATED WITH THAT CLASS.

THE OFFERED CERTIFICATES ARE COMPLEX SECURITIES AND IT IS IMPORTANT THAT YOU POSSESS, EITHER ALONE OR TOGETHER WITH AN INVESTMENT ADVISOR, THE EXPERTISE NECESSARY TO EVALUATE THE INFORMATION CONTAINED IN THE ACCOMPANYING TERM SHEET, THIS TERM SHEET SUPPLEMENT, THE PROSPECTUS SUPPLEMENT AND THE PROSPECTUS IN THE CONTEXT OF YOUR FINANCIAL SITUATION.

Geographic Concentration of the Mortgage Loans in Particular Jurisdictions May Result in Greater Losses If Those Jurisdictions Experience Economic Downturns	Different geographic regions of the United States from time to time will experience weaker regional economic conditions and housing markets, and, consequently, may experience higher rates of loss and delinquency on mortgage loans generally. Any concentration of the mortgage loans in a region may present risk considerations in addition to those generally present for similar mortgage-backed securities without that concentration. This may subject the mortgage loans held by the trust fund to the risk that a downturn in the economy in this region of the country would more greatly affect the mortgage pool than if the mortgage pool were more diversified.

	Because of the relative geographic concentration of the mortgaged properties within certain states, losses on the mortgage loans may be higher than would be the case if the mortgaged properties were more geographically diversified. For example, some of the mortgaged properties may be more susceptible to certain types of special hazards, such as earthquakes, hurricanes, floods, fires and other natural disasters and major civil disturbances, than residential properties located in other parts of the country.

	In addition, the economies of the states with high concentrations of mortgaged properties may be adversely affected to a greater degree than the economies of other areas of the country by certain regional developments. If the residential real estate markets in an area of concentration experience an overall decline in property values after the dates of origination of the respective mortgage loans, then the rates of delinquencies, foreclosures and losses on the mortgage loans may increase and the increase may be substantial.

	The concentration of mortgage loans with specific characteristics relating to the types of properties, property characteristics, and geographic location are likely to change over time. Principal payments may affect the concentration levels. Principal payments could include voluntary prepayments and prepayments resulting from casualty or condemnation, defaults and liquidations and from repurchases due to breaches of representations and warranties. Because principal payments on the mortgage loans are payable to the Subordinate Certificates at a slower rate than principal payments are made to the Senior Certificates, the Subordinate Certificates are more likely to be exposed to any risks associated with changes in concentrations of mortgage loan or property characteristics.

Effect on Yields Caused by Prepayments, Defaults and Losses	Mortgagors may prepay their mortgage loans in whole or in part at any time. A prepayment of a mortgage loan generally will result in a prepayment on the related certificates. We cannot predict the rate at which mortgagors will repay their mortgage loans. We cannot assure you that the actual prepayment rates of the mortgage loans included in the trust fund will conform to any historical prepayment rates or any forecasts of prepayment rates described or reflected in any reports or studies relating to pools of mortgage loans similar to the types of mortgage loans included in the trust fund.

	If you purchase your certificates at a discount and principal is repaid slower than you anticipate, then your yield may be lower than you anticipate.

	If you purchase your certificates at a premium and principal is repaid faster than you anticipate, then your yield may be lower than you anticipate.


	If you purchase a class of Class A-X Certificates and the Premium Loans in a related Loan Group prepay at a rate that is faster than you anticipate, then your yield may be significantly lower than you anticipate and you may not fully recoup your initial investment.

	If you purchase any other class of Interest Only Certificates and the related mortgage loans prepay at a rate that is faster than you anticipate, then your yield may be significantly lower than you anticipate and you may not fully recoup your initial investment.

	If you purchase a class of Class A-P Certificates and the Discount Loans in a related Loan Group prepay at a rate that is slower than you anticipate, then your yield may be lower than you anticipate.

	If you purchase any other class of Principal Only Certificates and the related mortgage loans prepay at a rate that is slower than you anticipate, then your yield may be lower than you anticipate.

	The rate of prepayments on the mortgage loans will be sensitive to prevailing interest rates. Generally, for fixed-rate mortgage loans, if prevailing interest rates decline significantly below the interest rates on the fixed-rate mortgage loans, the fixed-rate mortgage loans are more likely to prepay than if prevailing rates remain above the interest rates on the fixed-rate mortgage loans. Conversely, if prevailing interest rates rise significantly, prepayments on the fixed-rate mortgage loans may decrease.

	Certain of the mortgage loans require the mortgagor to pay a prepayment premium in certain instances if the mortgagor prepays the mortgage loan during a stated period after the mortgage loan was originated. A prepayment premium may or may not discourage a mortgagor from prepaying the related mortgage loan during the applicable period.

	Each originator made certain representations and warranties regarding the mortgage loans it sold to the sponsor. Upon a discovery of a breach of certain of these representations or warranties that materially and adversely affects the value of a mortgage loan, the party discovering such breach will give prompt written notice to the other parties as provided in the applicable agreement. Generally, within 60 to 90 days of the earlier of the discovery by and notice to the applicable originator of any such breach, that originator will be required to cure such breach, and if such breach cannot be cured within 90 days after the discovery of such breach, to repurchase that mortgage loan. Any such repurchase will have the same effect as a prepayment of a mortgage loan, as further described in this term sheet supplement. In addition, it is possible that an originator may not be capable of repurchasing any defective mortgage loans, for financial or other reasons. The inability of an originator to repurchase defective mortgage loans would likely cause the mortgage loans to experience higher rates of delinquencies, defaults and losses. As a result, shortfalls in the distributions due on the related certificates could occur.

	When the aggregate principal balance of the mortgage loans in a Loan Group or in related Loan Groups has been reduced to a specified percentage of that balance as of the cut-off date, the master servicer may purchase all of the mortgage loans in those Loan Groups and the related certificates will be retired. See "Description of the Certificates—Optional Purchase" in this term sheet supplement. If this happens, the purchase price paid by the master servicer will be passed through to the related certificateholders. This would have the same effect to the related classes of certificates as if all of the remaining mortgagors related to those Loan Groups had made prepayments in full.

	If the rate of default and the amount of losses on the mortgage loans is higher than you expect, then your yield may be lower than you expect.

	Because each of the Subordinate Certificates represents interests in all the mortgage loans in the related Loan Group or Loan Groups, the principal amounts of the Subordinate Certificates could be reduced to zero as a result of a disproportionately high amount of losses on the mortgage loans contributing to any Collateral Group within a related Loan Group. As a result, losses on the mortgage loans contributing to one Collateral Group will reduce the loss protection provided by the related Subordinate Certificates to the Senior Certificates corresponding to the other related Collateral Groups, and will increase the likelihood that losses will be allocated to those other Senior Certificates.

	The value of your certificates may be reduced if the rate of default or the amount of losses is higher than expected.

	If the performance of the related mortgage loans is substantially worse than assumed by the rating agencies, the ratings of any class of the certificates may be lowered in the future. This would probably reduce the value of those certificates. No one will be required to supplement any credit enhancement or to take any other action to maintain any rating of the certificates.

	Newly originated mortgage loans may be more likely to default, which may cause losses on the offered certificates.

	Defaults on mortgage loans tend to occur at higher rates during the early years of the mortgage loans. Most of the mortgage loans were originated within the one year period prior to their sale to the trust fund. As a result, the trust fund may experience higher rates of default than if the mortgage loans had been outstanding for a longer period of time.

	*The credit enhancement features may be inadequate to provide protection for the offered Certificates.*

	The credit enhancement features described in this term sheet supplement are intended to enhance the likelihood that holders of the Senior Certificates, and to a limited extent, the holders of the Senior Subordinate Certificates, will receive regular payments of interest and principal. However, we cannot assure you that the applicable credit enhancement will adequately cover any shortfalls in cash available to pay your certificates as a result of delinquencies or defaults on the related mortgage loans. If delinquencies or defaults occur on the related mortgage loans, neither the servicers nor any other entity will advance scheduled monthly payments of interest and principal on delinquent or defaulted mortgage loans if the advances are not likely to be recovered.

	If substantial losses occur as a result of defaults and delinquent payments on the related mortgage loans, you may suffer losses.

Effect of Mortgage Rates and Other Factors on the Certificate Interest Rates of the LIBOR Certificates	The LIBOR Certificates accrue interest at certificate interest rates based on the one-month LIBOR index plus specified margins or vary inversely with LIBOR, but are subject to certain limitations. Those limitations on the certificate interest rates for the LIBOR Certificates are, in part, based on the weighted average of the net interest rates on the mortgage loans, net of certain fees of the trust fund.

	A variety of factors could limit the certificate interest rates and adversely affect the yield to maturity on the LIBOR Certificates. Some of these factors are described below:

	The interest rates on the mortgage loans will not adjust. As a result of the limit on the certificate interest rates for the LIBOR Certificates, those LIBOR Certificates may accrue less interest than they would accrue if their certificate interest rates were based solely on the one-month LIBOR index plus the specified margins.

	The certificate interest rates for the LIBOR Certificates adjust monthly and are subject to maximum interest rate caps while the interest rates on the mortgage loans do not adjust. Consequently, the limit on the certificate interest rates for the LIBOR Certificates may limit increases in the certificate interest rates for those classes for extended periods in a rising interest rate environment.

	If, on any Distribution Date, the certificate interest rate on a class of LIBOR Certificates is limited by the applicable maximum interest rate cap, a "basis risk shortfall" will result. This amount will generally equal the excess of interest that would have been distributable absent application of the applicable maximum certificate interest rate over interest calculated at the maximum certificate interest rate. On any Distribution Date, the securities administrator will repay any basis risk shortfalls to the extent of amounts received under any interest rate cap agreement available for such purpose and to the extent of amounts available in the basis risk reserve fund as described in this term sheet supplement. There can be no assurance that such amounts will be sufficient to repay any basis risk shortfalls. The ratings on the LIBOR Certificates do not represent an assessment of the likelihood of the distribution of any basis risk shortfalls.

	If prepayments, defaults and liquidations occur more rapidly on the mortgage loans with relatively higher interest rates than on the mortgage loans with relatively lower interest rates, the certificate interest rates on the related LIBOR Certificates are more likely to be limited.

Prepayments on the Mortgage Loans Could Lead to Shortfalls in the Distribution of Interest on Your Certificates	When a voluntary principal prepayment is made by the mortgagor on a mortgage loan (excluding any payments made upon liquidation of any mortgage loan), the mortgagor is charged interest on the amount of prepaid principal only up to the date of the prepayment, instead of for a full month. However, principal prepayments will only be passed through to the holders of the certificates once a month on the Distribution Date which follows the prepayment period in which the prepayment was received by the applicable servicer. Each servicer is obligated to pay an amount without any right of reimbursement, for those shortfalls in interest collections payable on the certificates that are attributable to the difference between the interest paid by a mortgagor in connection with certain voluntary principal prepayments in full (and, in certain cases, in part), but only to the extent of one-half of the applicable monthly servicing fee for the related Distribution Date.

	If a servicer fails to make such compensating interest payments or the shortfall exceeds one-half of the applicable monthly servicing fee for the related Distribution Date, there will be fewer funds available for the distribution of interest on the related certificates. In addition, no compensating interest payments will be available to cover prepayment interest shortfalls resulting from partial prepayments or involuntary prepayments (such as liquidation of a defaulted mortgage loan). Such shortfalls of interest, if they result in the inability of the trust fund to pay the full amount of the current interest on the certificates, will result in a reduction of the yield on your certificates.

The Weighted Average Lives of, and the Yields to Maturity on, the Subordinate Certificates are Sensitive to Mortgagor Defaults and Losses on the Mortgage Loans	The weighted average lives of, and the yields to maturity on the certificates will be progressively more sensitive, in the reverse order of their seniority, 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 related mortgage loans is higher than those assumed by an investor in the offered certificates, the actual yield to maturity of such certificates may be lower than the yield anticipated by such holder based on such assumption. The timing of losses on the related 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 related mortgage loans 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. Losses on the mortgage loans in any Loan Group will be allocated first to the most junior class of related Subordinate Certificates then outstanding. If the total class principal balance of the related Subordinate Certificates has been reduced to zero, all further losses on those mortgage loans will be allocated to the related Senior Certificates on a pro rata basis; provided, that losses otherwise allocable to any class of Super Senior Certificates will instead be allocated to the related class or classes of Credit Support Certificates, until the class principal balance thereof has been reduced to zero. As a result of such reductions, less interest will accrue on such class or classes of certificates than would otherwise be the case.

	In addition, the effect on the market value of the Subordinate Certificates of changes in market interest rates or market yields for similar securities may be greater than for the Class A certificates.

Delay in Receipt of Liquidation Proceeds; Liquidation Proceeds May Be Less Than the Mortgage Loan Balance	Substantial delays could be encountered in connection with the liquidation of delinquent mortgage loans. Further, reimbursement of advances made on a mortgage loan, liquidation expenses such as legal fees, real estate taxes, hazard insurance and maintenance and preservation expenses may reduce the portion of liquidation proceeds payable on the related certificates. If a mortgaged property fails to provide adequate security for the mortgage loan related to your certificates, you will incur a loss on your investment if the credit enhancements are insufficient to cover the loss.

High Loan-to-Value Ratios Increase Risk of Loss	Mortgage loans with higher original loan-to-value ratios may present a greater risk of loss than mortgage loans with original loan-to-value ratios of 80% or below.

	Additionally, the determination of the value of a mortgaged property used in the calculation of the loan-to-value ratios of the mortgage loans may differ from the appraised value of such mortgaged properties if current appraisals were obtained.

The Transfer of Servicing May Result in Higher Delinquencies and Defaults Which May Adversely Affect the Yield on Your Certificates	It is possible that servicing of mortgage loans may be transferred in the future in accordance with the provisions of the master servicing and trust agreement and the related servicing agreement either because, with respect to the mortgage loans acquired through Goldman Sachs Mortgage Company’s mortgage conduit program, the party that owns the related servicing rights (which is currently Goldman Sachs Mortgage Company) elects to effect such a transfer or, with respect to all of the mortgage loans, as a result of the occurrence of unremedied events of default in a servicer’s performance under the related servicing agreement.

	All transfers of servicing involve the risk of disruption in collections due to data input errors, misapplied or misdirected payments, system incompatibilities, the requirement to notify the mortgagors about the servicing transfer, delays caused by the transfer of the related servicing mortgage files and records to the new servicer and other reasons. As a result of this servicing transfer or any delays associated with the transfer, the rate of delinquencies and defaults could increase at least for a period of time. We cannot assure you that there will be no disruptions associated with the transfer of servicing or that, if there are disruptions, that they will not adversely affect the yield on your certificates.

External Events May Increase the Risk of Loss on the Mortgage Loans	In response to previously executed and threatened terrorist attacks in the United States and foreign countries, the United States has initiated military operations and has placed a substantial number of armed forces reservists and members of the National Guard on active duty status. It is possible that the number of reservists and members of the National Guard placed on active duty status in the near future may increase. To the extent that a member of the military, or a member of the armed forces reserves or National Guard who is called to active duty, is a mortgagor of a mortgage loan in the trust fund, the interest rate limitation of the Servicemembers Civil Relief Act and any comparable state law, will apply. This may result in interest shortfalls on the mortgage loans, which, in turn will be allocated ratably in reduction of accrued interest on all classes of offered certificates, irrespective of the availability of excess cash flow or other credit enhancement. None of the depositor, the underwriter, the master servicer, the servicers, the securities administrator, the trustee or any other person has taken any action to determine whether any of the mortgage loans would be affected by such interest rate limitation. See "Legal Aspects of the Mortgage Loans—Servicemembers Civil Relief Act and the California Military and Veterans Code" in the prospectus.

The Certificates Are Obligations of the Trust Fund Only	The certificates will not represent an interest in or obligation of the depositor, the sponsor, the underwriter, the master servicer, the servicers, the securities administrator, the trustee or any of their respective affiliates. Neither the certificates nor the underlying mortgage loans will be guaranteed or insured by any governmental agency or instrumentality or by the depositor, the master servicer, the servicers, the securities administrator, the trustee or any of their respective affiliates. Proceeds of the assets included in the trust fund will be the sole source of payments on the certificates, and there will be no recourse to the depositor, the underwriter, the master servicer, the servicers, the securities administrator, the trustee or any other person in the event that such proceeds are insufficient or otherwise unavailable to make all payments provided for under the certificates.

Your Investment May Not Be Liquid	The underwriter intends to make a secondary market in the offered certificates, but it will have no obligation to do so. We cannot assure you that such 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. You are encouraged to consult your own legal advisors for assistance in determining the suitability of and consequences to you of the purchase, ownership, and sale of those certificates. See "Legal Investment" in this term sheet supplement and in the prospectus.

The Ratings on Your Certificates Could Be Reduced or Withdrawn	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.

The Offered Certificates May Not Be Suitable 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.


Failure of a Servicer to Perform or Insolvency of a Servicer May Adversely Affect the Yield on the Certificates	The amount and timing of distributions on your certificates generally will be dependent on the servicers performing their servicing obligations in an adequate and timely manner. See "The Servicers" in this term sheet supplement. If any servicer fails to perform its servicing obligations, this failure may result in an increase in the rates of delinquencies, defaults and losses on the mortgage loans.

Factors that Reduce Collections Could Cause Early Repayment, Delayed Payment or Reduced Payment on the Certificates	If any servicer becomes the subject of bankruptcy or similar proceedings, the trustee’s claim to collections in that servicer’s possession at the time of the bankruptcy filing or other similar filing may not be perfected. In this event, funds available to pay principal and interest on your certificates may be delayed or reduced. A decline in real estate values or changes in mortgage market interest rates may affect the yield on your certificates. If the residential real estate market in the locale of properties securing the mortgage loans underlying your certificates should experience an overall decline in property values so that the outstanding principal balances of the mortgage loans, and any secondary financing on the related mortgaged properties, become greater than or equal to the value of the related mortgaged properties, the actual rates of delinquencies, foreclosures and losses could be higher than those now generally experienced in the mortgage lending industry. To the extent that these losses are not covered by any applicable credit enhancement, investors in the certificates will bear all risk of loss resulting from default by mortgagors. The amount of losses will depend primarily upon the value of the mortgaged properties for recovery of the outstanding principal balance and unpaid interest of the defaulted mortgage loans.

The Rate of Principal Payments, Including Prepayments, on the Mortgage Loans May Affect Distributions to any PAC or TAC Certificates	The planned amortization classes, or PACs, and targeted amortization classes, or TACs, will generally be less affected by the rate of principal prepayments than other classes of certificates. This is because on each Distribution Date, these certificates are designed to receive principal distributions according to a schedule to be set forth in the prospectus supplement. See "Description of the Certificates—Priority of Distributions." The schedule for the PACs will assume that the rate of prepayments on the related mortgage loans remains between two prepayment rates based on the Bond Market Association’s Standard Prepayment Assumption Model or other prepayment model. The schedule for the TACs will assume that the rate of prepayments on the related mortgage loans remains at a specific rate based on the Bond Market Association’s Standard Prepayment Assumption Model or other prepayment model. However, there can be no assurance that the rate of prepayments on the mortgage loans will occur between those rates. If the mortgage loans prepay at a rate faster or slower than those rates, distributions of principal may no longer be made according to the related schedule. See "Yield and Prepayment Considerations," and "Yield and Prepayment Considerations—PAC and TAC Certificates."

Weighted Average Lives of the PAC and TAC Support Certificates Will Be Highly Sensitive to the Rate and Timing of Principal Prepayments	Any PAC or TAC support certificates have been designed to stabilize the related PAC or TAC certificates. As PAC and TAC support certificates, the amount distributable on any Distribution Date as principal to the class or classes of the PAC or TAC support certificates and the weighted average life of the class or classes of PAC or TAC support certificates will be highly sensitive to prepayments on the mortgage loans contributing to the related Collateral Group. If principal payments on the mortgage loans contributing to the related Collateral Group fall below a certain level for a Distribution Date, any PAC or TAC support certificates will receive no distributions of principal and if principal payments on the mortgage loans contributing to the related Collateral Group exceed a certain level for a Distribution Date, any PAC or TAC support certificates will be paid in full before the related PAC or TAC certificates. As a result, the amount of principal which PAC and TAC support certificates will receive on any Distribution Date and the weighted average life of these certificates will be highly dependent upon the rate and timing of principal prepayments on the mortgage loans in the related Collateral Group. If you are an individual investor you are encouraged to carefully consider these effects on your investment goals. These certificates may not be an appropriate investment for individual investors who seek a distribution of principal on a specific date or an otherwise predictable stream of distributions. See "Yield and Prepayment Considerations" and "Yield and Prepayment Considerations—Support Certificates."

Default Risk on Mortgage Loans with Interest Only Payments	Certain of the mortgage loans may provide for payment of interest at the related mortgage interest rate, but no payment of principal, for a certain period following the origination of the mortgage loan. Following that period, the monthly payment with respect to each of these mortgage loans will be increased to an amount sufficient to amortize the principal balance of the mortgage loan over the remaining term and to pay interest at the mortgage interest rate. The presence of these mortgage loans in the trust fund will, absent other considerations, result in longer weighted average lives of the related certificates than would have been the case had these mortgage loans not been included in the trust fund. If you purchase a related certificate at a discount, you should consider that the extension of weighted average lives could result in a lower yield than would be the case if these mortgage loans provided for payment of principal and interest on every payment date. In addition, a mortgagor may view the absence of any obligation to make a payment of principal during the interest only period as a disincentive to prepayment. If a recalculated monthly payment as described above is substantially higher than a mortgagor’s previous interest only monthly payment, that mortgage loan may be subject to an increased risk of delinquency and loss.

THE TRUST AGREEMENT

The Series 2006-2F Mortgage Pass-Through Certificates will be issued pursuant to the master servicing and trust agreement (the "Trust Agreement") among GSMSC, as Depositor, Wells Fargo Bank, N.A., as Master Servicer (in such capacity, the "Master Servicer") and Securities Administrator (in such capacity, the "Securities Administrator"), U.S. Bank National Association, as Trustee (the "Trustee"), and JPMorgan Chase Bank, National Association and Deutsche Bank National Trust Company, as Custodians (the "Custodians"). The mortgage loans will be assigned to the Trustee on behalf of the certificateholders. The certificates represent beneficial ownership interests in a trust fund (the "Trust Fund"), the assets of which consist primarily of (1) the Mortgage Loans, (2) such amounts or assets as from time to time are identified as deposited in respect of the Mortgage Loans into the Master Servicer Account or into a special purpose account (the "Certificate Account"), (3) any property acquired as a result of foreclosure of a Mortgage Loan or deed in lieu of foreclosure, (4) a security interest in insurance policies related to individual Mortgage Loans and (5) all proceeds of the foregoing. In exchange for the Mortgage Loans and other property, the Trustee will execute and the certificate registrar will authenticate and deliver the certificates to GSMSC. A schedule to the Trust Agreement will include information about each Mortgage Loan, including:

the original principal balance and the scheduled principal balance of such Mortgage Loan as of the close of business on the Cut-Off Date;

the maturity date of such Mortgage Loan; and

the mortgage interest rate of such Mortgage Loan.

The Trust Fund will also contain other property, including:

a security interest in insurance policies related to individual Mortgage Loans, if applicable;

any property that the Trust Fund acquires as a result of foreclosure or threatened foreclosure of a Mortgage Loan; and

amounts held in the Certificate Account.

Each Custodian will execute and deliver to the Trustee a custodial receipt representing that it possesses the respective mortgage loan files to which it agreed to act as custodian pursuant to the separate custodial agreement or custodial agreements, as the case may be. The Securities Administrator will perform certain obligations specified in the Trust Agreement with respect to making distributions on the offered certificates, including, but not limited to, registering and transferring the offered certificates and performing tax administration. In addition, the Trustee will be obligated to act as successor servicer in the event of the resignation or removal of any Servicer and a default by the Master Servicer of its obligation to appoint a successor servicer to assume the servicing duties of such removed or resigned Servicer. The Securities Administrator will act as certificate registrar of the certificates. The Depositor and the Servicers may maintain other banking relationships in the ordinary course of business with the Trustee and the Securities Administrator. Certificates may be surrendered and a copy of the Trust Agreement may be inspected at the corporate trust office of the Securities Administrator located at Sixth Street and Marquette Avenue, Minneapolis, Minnesota 55479. The Securities Administrator’s address for all other purposes is 9062 Old Annapolis Road, Columbia, Maryland 21045, or such other addresses as the Securities Administrator may designate from time to time by notice to the certificateholders, the Depositor, the Master Servicer and each Servicer. The Trust Agreement provides that Wells Fargo Bank, N.A., as Securities Administrator and U.S. Bank National Association, as Trustee under the Trust Agreement and their officers, employees or agents will be indemnified from the assets of the Trust Fund and will be held harmless against any loss, liability or expense incurred by the Securities Administrator or the Trustee, as applicable, arising out of its respective obligations under the Trust Agreement, other than incurred by reason of willful misfeasance or negligence in the performance of its respective duties under the Trust Agreement. Each Custodian is similarly indemnified pursuant to the applicable custodial agreement.

The Securities Administrator will be entitled to retain as compensation for its services, any interest or other income earned on funds on deposit in the Certificate Account pending distribution to certificateholders.

The Trustee is eligible to serve as such under the Trust Agreement only if it is a corporation or banking association organized and doing business under the laws of the United States or any state thereof, is authorized under such laws to exercise corporate trust powers, is subject to supervision or examination by federal or state authority, and has a combined capital and surplus of at least $50,000,000.

The Trustee may, upon written notice to each Servicer, the Master Servicer, the Securities Administrator, the Depositor and all certificateholders, resign at any time, in which event the Depositor will be obligated to appoint a successor. If no successor has been appointed and has accepted appointment within 60 days after giving such notice of resignation, the resigning party may petition any court of competent jurisdiction for appointment of a successor. Any such successor must be approved by the Rating Agencies. The Trustee may also be removed at any time (i) by the Depositor or (ii) by holders of certificates evidencing at least 51% of the voting rights. Any removal or resignation of the Trustee and appointment of a successor as described above will not become effective until acceptance of appointment by the successor.

DESCRIPTION OF THE MORTGAGE POOL

General

The pool of mortgage loans (the "Mortgage Loans") will consist of conventional fixed-rate, fully amortizing mortgage loans secured by first liens on fee simple interests in one- to four-family residential real properties (each, a "Mortgaged Property"). The Mortgaged Properties, which may include one- to four- family dwelling units, individual condominium units, cooperatives, individual units in planned unit developments and other attached dwelling units which are part of buildings consisting of more than four units (so long as the Mortgaged Property consists of no more than four units), have the additional characteristics described in the prospectus and the term sheet.

Substantially all of the Mortgage Loans (other than any interest only loans, which will not require scheduled payments of principal for a certain period after origination will have principal and interest payable on the first day of each month (the "Due Date"). Certain of the risks of loss on some of the Mortgage Loans will be covered up to specified limits by lender-paid primary mortgage insurance policies.

All of the Mortgage Loans were purchased by Goldman Sachs Mortgage Company ("GSMC") from Countrywide Home Loans, IndyMac Bank, F.S.B. ("IndyMac"), GMAC Mortgage Corporation ("GMACM") and certain other mortgage loan originators and were acquired by GSMC from such originators and certain entities that sold mortgage loans to GSMC under its mortgage conduit program (the "Conduit Program") (each of such entities, together with Countrywide Home Loans, IndyMac and GMACM, a "Loan Seller") pursuant to various sale and servicing agreements (or, in the case of the Mortgage Loans acquired from Countrywide Home Loans, which will be serviced by Countrywide Servicing, such Mortgage Loans were acquired pursuant to a seller’s warranty agreement and will be serviced by Countrywide Servicing pursuant to a servicing agreement) (or, in the case of the Mortgage Loans acquired through the Conduit Program, such Mortgage Loans were acquired pursuant to various master loan purchase agreements between the applicable sellers and GSMC and will be serviced for GSMC, as owner of the servicing rights, by Countrywide Servicing pursuant to a servicing agreement) (each of the foregoing sale and servicing agreements, servicing agreements, seller’s warranty agreements and master loan purchase agreements, a "Sale and Servicing Agreement" and together, the "Sale and Servicing Agreements"). Each Loan Seller, under the related Sale and Servicing Agreement, made certain representations and warranties (see "—Representations and Warranties Regarding the Mortgage Loans" below) regarding the Mortgage Loans. Each Sale and Servicing Agreement will be assigned to the Trustee insofar as it relates to the related Mortgage Loans.

The Goldman Sachs Mortgage Conduit Program

The information set forth below has been provided by GSMC.

GSMC acquires its mortgage loans through two primary channels: (i) its Conduit Program, pursuant to which it acquires mortgage loans from various banks, savings and loan associations, mortgage bankers and other mortgage loan originators and purchasers of mortgage loans in the secondary market and (ii) bulk acquisitions in the secondary market. GSMC will acquire mortgage loans secured by first or second liens on the related mortgaged properties.

All of the mortgage loans acquired by GSMC through the Conduit Program were acquired generally in accordance with the underwriting criteria described in this section. In certain instances, compensating factors demonstrated to the mortgage loan originator by a prospective borrower may warrant GSMC to make certain exceptions to these guidelines. In such instances GSMC would purchase a mortgage loan that did not completely conform to the guidelines set out below.

Mortgage Conduit Underwriting Guidelines

The underwriting guidelines used to originate certain of the mortgage loans acquired by GSMC through the Conduit Program are different from and, in some cases, less stringent than, the underwriting standards established by Fannie Mae or Freddie Mac. The differences primarily relate to loan characteristics such as original principal balances, loan-to-value ratios, borrower income, required documentation, interest rates, borrower occupancy of the mortgaged property and/or property types. Mortgage loans originated pursuant to underwriting standards different from those of Fannie Mae and Freddie Mac may experience higher rates of delinquency and/or credit losses than mortgage loans originated by Fannie Mae or Freddie Mac. In addition, compensating factors demonstrated by a prospective borrower may warrant certain exceptions to the underwriting standards described in this section.

Generally, each borrower applying for a mortgage loan must complete a credit application. The credit application is designed to provide the originating lender with relevant credit information about the prospective borrower such as information with respect to the borrower's assets, liabilities, income (except as described below), credit history, employment history and personal information. In addition, prospective borrowers generally must provide an authorization to apply for a credit report. A credit report summarizes the borrower's past credit experience with lenders and other debtors, including any record of bankruptcy. Sometimes, the borrower is required to authorize the originating lender to verify deposits at financial institutions identified by the borrower as institutions at which the borrower maintains demand or savings accounts. The originating lender may also consider certain non-wage income of the borrower in the underwriting process, including income derived from mortgaged properties that are investment properties or two- to four-unit dwellings. Generally, the originating lender will not consider income derived from vacation or second homes in the underwriting process. Certain borrowers with acceptable payment histories are not required to state their income on their loan application and, as a result, the originating lender does not verify their income.

Based on the data referred to above (and verification of that data, to the extent required), the originating lender makes a determination about whether the borrower's monthly income (if required to be stated) will be sufficient to enable the borrower to meet its monthly obligations on the mortgage loan and other expenses related to the property, including property taxes, utility costs, standard hazard insurance and other fixed and revolving obligations other than housing expenses. Generally, scheduled payments on a mortgage loan during the first twelve months of its term plus taxes and insurance and all scheduled payments on obligations that extend beyond ten months may equal no more than a specified percentage of the prospective borrower's gross income. The permitted percentage is determined on the basis of various underwriting criteria, including the LTV ratio of the mortgage loan and, in certain instances, the amount of liquid assets available to the borrower after origination.

In addition to its "full" documentation program, loans acquired by GSMC through the Conduit Program may also be originated under the following limited documentation programs: "reduced income," "stated income," "stated income/stated assets" or "no doc." These limited documentation programs are designed to streamline the underwriting process.

The "reduced income," "stated income," "stated income/stated asset" and "no doc" programs generally require less documentation and verification than do "full" documentation programs.

Generally, the "full" documentation program requires information with respect to the borrower's income and assets (i.e., standard Fannie Mae/Freddie Mac approved forms for verification of income/employment, assets and certain payment histories). However, alternative forms of standard verifications may also be used for income (i.e., W-2 forms, tax returns and/or pay stubs) and assets (i.e., bank statements). Generally, under "full" documentation programs at least one year of income documentation is provided. Employment history must also be verified by the originating lender.

Generally, the "reduced" documentation program requires similar information with respect to the borrower's income as a "full" documentation program. However, under "reduced" documentation programs only six months of income documentation is generally provided. Employment history must also be verified by the originating lender.

Generally, under the "stated income" program, the borrower's income is stated on the credit application but not verified by the originator. However, employment history must be verified by the originating lender.

Generally, under the "stated income/stated assets" program, both income and assets are stated on the loan application, but the originator verifies neither; although the stated income must be reasonable relative to the borrower's stated employment. However, employment history must be verified by the originating lender.

Generally, under the "no doc" program, the borrower's income and assets are neither stated on the credit application nor verified by the originator. The underwriting for mortgage loans originated under a "no doc" program may be based primarily or entirely on the appraised value of the mortgaged property and the LTV ratio at origination as well as on the payment history and credit score of the related borrower. Employment history is neither stated nor verified by the originating lender.

The following charts summarize GSMC's maximum loan-to-value ratio requirements under its various documentation programs:

An appraisal is generally conducted on each mortgaged property by the originating lender. The appraisal must be conducted in accordance with established appraisal procedure guidelines acceptable to the originator in order to determine the adequacy of the mortgaged property as security for repayment of the related mortgage loan. All appraisals must be on forms acceptable to Fannie Mae and/or Freddie Mac and conform to the Uniform Standards of Professional Appraisal Practice adopted by the Appraisal Standards Board of the Appraisal Foundation. Appraisers may be staff licensed appraisers employed by the originator or independent licensed appraisers selected in accordance with established appraisal procedure guidelines acceptable to the originator. Generally, the appraisal procedure guidelines require the appraiser or an agent on its behalf to inspect the property personally and verify whether the property is in good condition and that, if new, construction has been substantially completed. The appraisal generally will be based upon a market data analysis of recent sales of comparable properties and, when deemed applicable, an analysis based on income generated from the property or a replacement cost analysis based on the current cost of constructing or purchasing a similar property.

Countrywide Underwriting Guidelines

Note: Loan-to-Value Ratio as used in the Countrywide Underwriting Guidelines below has the following meaning:

The "Loan-to-Value Ratio" of a mortgage loan at any given time is a fraction, expressed as a percentage, the numerator of which is the principal balance of the related mortgage loan at the date of determination and the denominator of which is

in the case of a purchase, the lesser of the selling price of the related mortgaged property or its appraised value at the time of sale or

in the case of a refinance, the appraised value of the mortgaged property at the time of the refinance, except as described in the following sentence.

If the borrower is refinancing an existing mortgage loan that was originated or acquired by Countrywide Home Loans, and that existing mortgage loan meets the delinquency criteria set forth in the related servicing agreement, then with respect to the refinanced mortgage loan,

if the loan-to-value ratio at the time of the origination of the mortgage loan being refinanced was 80% or less and the loan amount of the new loan being originated is $650,000 or less, then the "Loan-to-Value Ratio" will be the ratio of the principal amount of the new mortgage loan being originated divided by the appraised value of the related mortgaged property at the time of the origination of the mortgage loan being refinanced; or

if the loan-to-value ratio at the time of the origination of the mortgage loan being refinanced was greater than 80% or the loan amount of the new loan being originated is greater than $650,000, then the "Loan-to-Value Ratio" will be the ratio of the principal amount of the new mortgage loan being originated divided by the appraised value of the related mortgaged property as determined by a limited appraisal report at the time of the origination of the new mortgage loan. See "—Underwriting Standards—General" below.

No assurance can be given that the value of any mortgaged property has remained or will remain at the level that existed on the appraisal or sales date. If residential real estate values generally or in a particular geographic area decline, the Loan-to-Value Ratios might not be a reliable indicator of the rates of delinquencies, foreclosures and losses that could occur with respect to the mortgage loans.

Underwriting Standards

General

Countrywide Home Loans, Inc., a New York corporation ("Countrywide Home Loans"), has been originating mortgage loans since 1969. Countrywide Home Loans’ underwriting standards are applied in accordance with applicable federal and state laws and regulations.

As part of its evaluation of potential borrowers, Countrywide Home Loans generally requires a description of income. If required by its underwriting guidelines, Countrywide Home Loans obtains employment verification providing current and historical income information and/or a telephonic employment confirmation. Such employment verification may be obtained, either through analysis of the prospective borrower’s recent pay stub and/or W-2 forms for the most recent two years, relevant portions of the most recent two years’ tax returns, or from the prospective borrower’s employer, wherein the employer reports the length of employment and current salary with that organization. Self-employed prospective borrowers generally are required to submit relevant portions of their federal tax returns for the past two years.

In assessing a prospective borrower’s creditworthiness, Countrywide Home Loans may use FICO Credit Scores. "FICO Credit Scores" are statistical credit scores designed to assess a borrower’s creditworthiness and likelihood to default on a consumer obligation over a two-year period based on a borrower’s credit history. FICO Credit Scores were not developed to predict the likelihood of default on mortgage loans and, accordingly, may not be indicative of the ability of a borrower to repay its mortgage loan. FICO Credit Scores range from approximately 250 to approximately 900, with higher scores indicating an individual with a more favorable credit history compared to an individual with a lower score. Under Countrywide Home Loans’ underwriting guidelines, borrowers possessing higher FICO Credit Scores, which indicate a more favorable credit history and who give Countrywide Home Loans the right to obtain the tax returns they filed for the preceding two years, may be eligible for Countrywide Home Loans’ processing program (the "Preferred Processing Program"). Countrywide Home Loans may waive some documentation requirements for mortgage loans originated under the Preferred Processing Program.

Periodically the data used by Countrywide Home Loans to complete the underwriting analysis may be obtained by a third party, particularly for mortgage loans originated through a loan correspondent or mortgage broker. In those instances, the initial determination as to whether a mortgage loan complies with Countrywide Home Loans’ underwriting guidelines may be made by an independent company hired to perform underwriting services on behalf of Countrywide Home Loans, the loan correspondent or mortgage broker. In addition, Countrywide Home Loans may acquire mortgage loans from approved correspondent lenders under a program pursuant to which Countrywide Home Loans delegates to the correspondent the obligation to underwrite the mortgage loans to Countrywide Home Loans’ standards. Under these circumstances, the underwriting of a mortgage loan may not have been reviewed by Countrywide Home Loans before acquisition of the mortgage loan and the correspondent represents that Countrywide Home Loans’ underwriting standards have been met. After purchasing mortgage loans under those circumstances, Countrywide Home Loans conducts a quality control review of a sample of the mortgage loans. The number of loans reviewed in the quality control process varies based on a variety of factors, including Countrywide Home Loans’ prior experience with the correspondent lender and the results of the quality control review process itself.

Countrywide Home Loans’ underwriting standards are applied by or on behalf of Countrywide Home Loans to evaluate the prospective borrower’s credit standing and repayment ability and the value and adequacy of the mortgaged property as collateral. Under those standards, a prospective borrower must generally demonstrate that the ratio of the borrower’s monthly housing expenses (including principal and interest on the proposed mortgage loan and, as applicable, the related monthly portion of property taxes, hazard insurance and mortgage insurance) to the borrower’s monthly gross income and the ratio of total monthly debt to the monthly gross income (the "debt-to-income" ratios) are within acceptable limits. If the prospective borrower has applied for a fully amortizing 3/1 Mortgage Loan or 3/27 Mortgage Loan and the Loan-to-Value Ratio is less than or equal to 75%, the interest component of the monthly housing expense is calculated based on the initial loan interest rate; if the Loan-to-Value Ratio exceeds 75%, the interest component of the monthly housing expense calculation is based on the initial loan interest rate plus 2%. If the prospective borrower has applied for an interest only 3/1 Mortgage Loan or 3/27 Mortgage Loan or an interest only or fully amortizing 5/1 Mortgage Loan, a 5/25 Mortgage Loan, a 7/1 Mortgage Loan, a 7/23 Mortgage Loan, a 10/1 Mortgage Loan or a 10/20 Mortgage Loan, the interest component of the monthly housing expense is calculated based on the initial loan interest rate. The maximum acceptable debt-to-income ratio, which is determined on a loan-by-loan basis varies depending on a number of underwriting criteria, including the Loan-to-Value Ratio, loan purpose, loan amount and credit history of the borrower. In addition to meeting the debt-to-income ratio guidelines, each prospective borrower is required to have sufficient cash resources to pay the down payment and closing costs. Exceptions to Countrywide Home Loans’ underwriting guidelines may be made if compensating factors are demonstrated by a prospective borrower. Additionally, Countrywide Home Loans does permit its adjustable rate mortgage loans, hybrid adjustable rate mortgage loans and negative amortization mortgage loans to be assumed by a purchaser of the related mortgaged property, so long as the mortgage loan is in its adjustable rate period (except for a 3/1 Mortgage Loan, which may be assumed during the fixed rate period) and the related purchaser meets Countrywide Home Loans’ underwriting standards that are then in effect.

Countrywide Home Loans may provide secondary financing to a borrower contemporaneously with the origination of a mortgage loan, subject to the following limitations: the Loan-to-Value Ratio of the senior (i.e., first) lien may not exceed 80% and the combined Loan-to-Value Ratio may not exceed 100%. Countrywide Home Loans’ underwriting guidelines do not prohibit or otherwise restrict a borrower from obtaining secondary financing from lenders other than Countrywide Home Loans, whether at origination of the mortgage loan or thereafter.

For all mortgage loans originated or acquired by Countrywide Home Loans, Countrywide Home Loans obtains a credit report relating to the applicant from a credit reporting company. The credit report typically 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, dispossession, suits or judgments. All adverse information in the credit report is required to be explained by the prospective borrower to the satisfaction of the lending officer.

Except with respect to the mortgage loans originated pursuant to its Streamlined Documentation Program whose values were confirmed with a Fannie Mae proprietary automated valuation model, Countrywide Home Loans obtains appraisals from independent appraisers or appraisal services for properties that are to secure mortgage loans. The appraisers inspect and appraise the proposed mortgaged property and verify that the property is in acceptable condition. Following each appraisal, the appraiser prepares a report which includes a market data analysis based on recent sales of comparable homes in the area and, when deemed appropriate, a replacement cost analysis based on the current cost of constructing a similar home. All appraisals are required to conform to Fannie Mae or Freddie Mac appraisal standards then in effect.

Countrywide Home Loans requires title insurance on all of its mortgage loans secured by first liens on real property. Countrywide Home Loans also requires that fire and extended coverage casualty insurance be maintained on the mortgaged property in an amount at least equal to the principal balance of the related single-family mortgage loan or the replacement cost of the mortgaged property, whichever is less.

Countrywide Home Loans’ underwriting guidelines for fixed-period adjustable rate mortgage loans generally allow Loan-to-Value Ratios at origination of up to 95% for purchase money or rate and term refinance mortgage loans with original principal balances of up to $500,000, up to 90% for mortgage loans with original principal balances of up to $650,000, up to 80% for mortgage loans with original principal balances of up to $1,000,000 and up to 65% for mortgage loans with original principal balances of up to $1,500,000, and up to 60% for mortgage loans with original principal balances of up to $2,000,000. Loans exceeding $650,000 are restricted to properties located in major metropolitan areas only.

For cash out refinance mortgage loans with original principal balances of up to $650,000, Countrywide Home Loans’ underwriting guidelines generally allow Loan-to-Value Ratios at origination of up to 75%. The maximum "cash-out" amount permitted is $200,000 and is based in part on the original Loan-to-Value Ratio of the related mortgage loan. As used in this term sheet supplement, a refinance mortgage loan is classified as a cash-out refinance mortgage loan by Countrywide Home Loans if the borrower retains an amount greater than the lesser of 2.0% of the entire amount of the proceeds from the refinancing of the existing loan, or $2,000.

Under its underwriting guidelines, Countrywide Home Loans generally permits a debt-to-income ratio based on the borrower’s monthly housing expenses of up to 33% and a debt-to-income ratio based on the borrower’s total monthly debt of up to 38%.

The nature of the information that a borrower is required to disclose and whether the information is verified depends, in part, on the documentation program used in the origination process. In general under the Full Documentation Loan Program (the "Full Documentation Program"), each prospective borrower is required to complete an application which includes information with respect to the applicant’s assets, liabilities, income, credit history, employment history and other personal information. Self-employed individuals are generally required to submit their two most recent federal income tax returns. Under the Full Documentation Program, Countrywide Home Loans verifies the information contained in the application relating to employment, income, assets and mortgages.

A prospective borrower may be eligible for a loan approval process that limits or eliminates Countrywide Home Loans’ standard disclosure or verification requirements or both. Countrywide Home Loans offers the following documentation programs as alternatives to its Full Documentation Program: an Alternative Documentation Loan Program (the "Alternative Documentation Program"), a Reduced Documentation Loan Program (the "Reduced Documentation Program"), a CLUES Plus Documentation Loan Program (the "CLUES Plus Documentation Program"), a Streamlined Documentation Loan Program (the "Streamlined Documentation Program"), a No Income/No Asset Documentation Loan Program (the "No Income/No Asset Documentation Program") and a Stated Income/Stated Asset Documentation Loan Program (the "Stated Income/Stated Asset Documentation Program").

The Alternative Documentation Program permits a borrower to provide W-2 forms instead of tax returns covering the most recent two years, permits bank statements in lieu of verification of deposits and permits alternative methods of employment verification.

Under the Reduced Documentation Program, some underwriting documentation concerning income and employment verification is waived. Countrywide Home Loans obtains from a prospective borrower either a verification of deposit or bank statements for the two-month period immediately before the date of the mortgage loan application or verbal verification of employment. Because information relating to a prospective borrower’s income and employment is not verified, the borrower’s debt-to-income ratios are calculated based on the information provided by the borrower in the mortgage loan application. The maximum Loan-to-Value Ratio, including secondary financing, ranges up to 70% maximum.

The CLUES Plus Documentation Program permits the verification of employment by alternative means, if necessary, including verbal verification of employment or reviewing paycheck stubs covering the pay period immediately prior to the date of the mortgage loan application. To verify the borrower’s assets and the sufficiency of the borrower’s funds for closing, Countrywide Home Loans obtains deposit or bank account statements from each prospective borrower for the month immediately prior to the date of the mortgage loan application. Under the CLUES Plus Documentation Program, the maximum Loan-to-Value Ratio is 75% and property values may be based on appraisals comprising only interior and exterior inspections. Cash-out refinances and investor properties are not permitted under the CLUES Plus Documentation Program.

The Streamlined Documentation Program is available for borrowers who are refinancing an existing mortgage loan that was originated or acquired by Countrywide Home Loans, provided that, among other things, the mortgage loan has not been more than 30 days delinquent in payment during the previous twelve-month period. Under the Streamlined Documentation Program, appraisals are obtained only if the loan being refinanced had a Loan-to-Value Ratio at the time of origination in excess of 80% or if the loan amount of the new loan being originated is greater than $650,000. In addition, under the Streamlined Documentation Program, a credit report is obtained but only a limited credit review is conducted, no income or asset verification is required, and telephonic verification of employment is permitted. The maximum Loan-to-Value Ratio under the Streamlined Documentation Program ranges up to 95%.

Under the No Income/No Asset Documentation Program, no documentation relating to a prospective borrower’s income, employment or assets is required and therefore debt-to-income ratios are not calculated or included in the underwriting analysis, or if the documentation or calculations are included in a mortgage loan file, they are not taken into account for purposes of the underwriting analysis. This program is limited to borrowers with excellent credit histories. Under the No Income/No Asset Documentation Program, the maximum Loan-to-Value Ratio, including secondary financing, is 95%.

Under the Stated Income/Stated Asset Documentation Program, the mortgage loan application is reviewed to determine that the stated income is reasonable for the borrower’s employment and that the stated assets are consistent with the borrower’s income. The Stated Income/Stated Asset Documentation Program permits maximum Loan-to-Value Ratios up to 90%.

IndyMac Bank acquires mortgage loans principally through four channels: mortgage professionals, consumer direct, correspondent and conduit. IndyMac Bank also acquires a relatively small number of mortgage loans through other channels.

Mortgage professionals: Mortgage brokers, mortgage bankers, financial institutions and homebuilders who have taken applications from prospective borrowers and submitted those applications to IndyMac Bank.

Consumer direct: Mortgage loans initiated through direct contact with the borrower. This contact may arise from internet advertising and IndyMac Bank website traffic, affinity relationships, company referral programs, realtors and through its Southern California retail banking branches.

Correspondent: Mortgage brokers, mortgage bankers, financial institutions and homebuilders who sell previously funded mortgage loans to IndyMac Bank.

Conduit: IndyMac Bank acquires pools of mortgage loans in negotiated transactions either with the original mortgagee or an intermediate owner of the mortgage loans.

IndyMac Bank approves each mortgage loan seller prior to the initial transaction on the basis of the seller’s financial and management strength, reputation and prior experience. Sellers are periodically reviewed and if their performance, as measured by compliance with the applicable loan sale agreement, is unsatisfactory, IndyMac Bank will cease doing business with them.

Underwriting Process

Mortgage loans that are acquired by IndyMac Bank are underwritten by IndyMac Bank according to IndyMac Bank’s underwriting guidelines, which also accept mortgage loans meeting Fannie Mae or Freddie Mac guidelines regardless of whether such mortgage loans would otherwise meet IndyMac Bank’s guidelines, or pursuant to an exception to those guidelines based on IndyMac Bank’s procedures for approving such exceptions. Conventional mortgage loans are loans that are not insured by the FHA or partially guaranteed by the VA. Conforming mortgage loans are loans that qualify for sale to Fannie Mae and Freddie Mac, whereas non-conforming mortgage loans are loans that do not so qualify. Non-conforming mortgage loans originated or purchased by IndyMac Bank pursuant to its underwriting programs typically differ from conforming loans primarily with respect to loan-to-value ratios, borrower income, required documentation, interest rates, borrower occupancy of the mortgaged property and/or property types. To the extent that these programs reflect underwriting standards different from those of Fannie Mae and Freddie Mac, the performance of loans made pursuant to these different underwriting standards may reflect higher delinquency rates and/or credit losses.

IndyMac Bank has two principal underwriting methods designed to be responsive to the needs of its mortgage loan customers: traditional underwriting and e-MITS (Electronic Mortgage Information and Transaction System) underwriting. E-MITS is an automated, internet-based underwriting and risk-based pricing system. IndyMac Bank believes that e-MITS generally enables it to estimate expected credit loss, interest rate risk and prepayment risk more objectively than traditional underwriting and also provides consistent underwriting decisions. IndyMac Bank has procedures to override an e-MITS decision to allow for compensating factors.

IndyMac Bank’s underwriting criteria for traditionally underwritten mortgage loans includes an analysis of the borrower’s credit history, ability to repay the mortgage loan and the adequacy of the mortgaged property as collateral. Traditional underwriting decisions are made by individuals authorized to consider compensating factors that would allow mortgage loans not otherwise meeting IndyMac Bank’s guidelines.

In determining a borrower’s FICO Credit Score, IndyMac Bank generally selects the middle credit score of the scores provided by each of the three major U.S. credit repositories (Equifax, TransUnion and Experian) for each borrower, and then selects the lowest of these scores. In some instances, IndyMac Bank selects the middle score of the borrower with the largest amount of qualifying income among all of the borrowers on the mortgage loan. A FICO Credit Score might not be available for a borrower due to insufficient credit information on file with the credit repositories. In these situations, IndyMac Bank will establish a borrower’s credit history through documentation of alternative sources of credit such as utility payments, auto insurance payments and rent payments. In addition to the FICO Credit Score, other information regarding a borrower’s credit quality is considered in the loan approval process, such as the number and degree of any late mortgage or rent payments within the preceding 12-month period, the age of any foreclosure action against any property owned by the borrower, the age of any bankruptcy action, the number of seasoned tradelines reflected on the credit report and any outstanding judgments, liens, charge-offs or collections.

For each mortgage loan with a Loan-to-Value Ratio at origination exceeding 80%, IndyMac Bank will usually require a primary mortgage guarantee insurance policy that conforms to the guidelines of Fannie Mae and Freddie Mac. After the date on which the Loan-to-Value Ratio of a mortgage loan is 80% or less, either because of principal payments on the mortgage loan or because of a new appraisal of the mortgaged property, no primary mortgage guaranty insurance policy will be required on that mortgage loan.

All of the insurers that have issued primary mortgage guaranty insurance policies with respect to the mortgage loans meet Fannie Mae’s or Freddie Mac’s standards or are acceptable to the Rating Agencies. In some circumstances, however, IndyMac Bank does not require primary mortgage guaranty insurance on mortgage loans with Loan-to-Value Ratios greater than 80%.

IndyMac Bank purchases loans that have been originated under one of seven documentation programs: Full/Alternate, FastForward, Limited, Stated Income, No Ratio, No Income/No Asset and No Doc. In general, documentation types that provide for less than full documentation of employment, income and liquid assets require higher credit quality and have lower loan-to-value ratios and loan amount limits.

Under the Full/Alternate Documentation Program, the prospective borrower’s employment, income and assets are verified through written documentation such as tax returns, pay stubs or W-2 forms. . Generally, a two-year history of employment or continuous source of income is required to demonstrate adequacy and continuance of income. Borrowers applying under the Full/Alternate Documentation Program may, based on certain loan characteristics and higher credit quality, qualify for IndyMac Bank’s FastForward program and be entitled to income and asset documentation relief. Borrowers who qualify for FastForward must state their income, provide a signed Internal Revenue Service Form 4506 (authorizing IndyMac Bank to obtain copies of their tax returns), and state their assets; IndyMac Bank does not require any verification of income or assets under this program.

The Limited Documentation Program is similar to the Full/Alternate Documentation Program except that borrowers generally must document income and employment for one year (rather than two, as required by the Full/Alternate Documentation Program). Borrowers under the Limited Documentation Program may use bank statements to verify their income and employment. If applicable, written verification of a borrower’s assets is required under this program.

The Stated Income Documentation Program requires prospective borrowers to provide information regarding their assets and income. Information regarding a borrower’s assets, if applicable, is verified through written communications. Information regarding income is not verified and employment verification may not be written.

The No Ratio Program requires prospective borrowers to provide information regarding their assets, which is then verified through written communications. The No Ratio Program does not require prospective borrowers to provide information regarding their income, but employment may not be written.

Under the No Income/No Asset Documentation Program and the No Doc Documentation Program, emphasis is placed on the credit score of the prospective borrower and on the value and adequacy of the mortgaged property as collateral, rather than on the income and the assets of the prospective borrower. Prospective borrowers are not required to provide information regarding their assets or income under either program, although under the No Income/No Asset Documentation Program, employment is orally verified.

IndyMac Bank generally will re-verify income, assets, and employment for mortgage loans it acquires through the wholesale channel, but not for mortgage loans acquired through other channels.

Maximum loan-to-value and combined loan-to-value ratios and loan amounts are established according to the occupancy type, loan purpose, property type, FICO Credit Score, number of previous late mortgage payments, and the age of any bankruptcy or foreclosure actions. Additionally, maximum total monthly debt payments-to-income ratios and cash-out limits may be applied. Other factors may be considered in determining loan eligibility such as a borrower’s residency and immigration status, whether a non-occupying borrower will be included for qualification purposes, sales or financing concessions included in any purchase contract, the acquisition cost of the property in the case of a refinance transaction, the number of properties owned by the borrower, the type and amount of any subordinate mortgage, the amount of any increase in the borrower’s monthly mortgage payment compared to previous mortgage or rent payments and the amount of disposable monthly income after payment of all monthly expenses.

To determine the adequacy of the property to be used as collateral, an appraisal is generally made of the subject property in accordance with the Uniform Standards of Profession Appraisal Practice. The appraiser generally inspects the property, analyzes data including the sales prices of comparable properties and issues an opinion of value using a Fannie Mae/Freddie Mac appraisal report form, or other acceptable form. In some cases, an automated valuation model (AVM) may be used in lieu of an appraisal. AVMs are computer programs that use real estate information, such as demographics, property characteristics, sales prices, and price trends to calculate a value for the specific property. The value of the property, as indicated by the appraisal or AVM, must support the loan amount.

Underwriting procedures vary by channel of origination. Generally, mortgage loans originated through the mortgage professional channel will be submitted to e-MITS for assessment and subjected to a full credit review and analysis. Mortgage loans that do not meet IndyMac Bank’s guidelines may be manually re-underwritten and approved under an exception to those underwriting guidelines. Mortgage loans originated through the consumer direct channel are subjected to essentially the same procedures, modified as necessary to reflect the fact that no third-party contributes to the preparation of the credit file.

IndyMac Bank currently operates two mortgage loan purchase programs as part of its correspondent channel:

Prior Approval Program. Under this program, IndyMac Bank performs a full credit review and analysis of each mortgage loan generally with the same procedures used for mortgage loans originated through the mortgage professionals channel. Only after IndyMac Bank issues an approval notice to a loan originator is a mortgage loan eligible for purchase pursuant to this program.

Preferred Delegated Underwriting Program. Under this program, loan originators that meet certain eligibility requirements are allowed to tender mortgage loans for purchase without the need for IndyMac Bank to verify mortgagor information. The eligibility requirements for participation in the Preferred Delegated Underwriting Program vary based on the net worth of the loan originators with more stringent requirements imposed on loan originators with a lower net worth. Loan originators are required to submit a variety of information to IndyMac Bank for review, including their current audited financial statements, their quality control policies and procedures, their current errors and omissions/fidelity insurance coverage evidencing blanket coverage in a minimum amount of $300,000, at least three underwriters’ resumes showing at least three years experience or a direct endorsement designation, and at least two references from mortgage insurance companies. Loan originators are required to have an active, traditional warehouse line of credit, which is verified together with the bailee letter and wire instructions. IndyMac Bank requires each loan originator to be recertified on an annual basis to ensure that it continues to meet the minimum eligibility guidelines for the Preferred Delegated Underwriting Program.

Under the Preferred Delegated Underwriting Program, each eligible loan originator is required to underwrite mortgage loans in compliance with IndyMac Bank’s underwriting guidelines usually by use of e-MITS or, infrequently, by submission of the mortgage loan to IndyMac Bank for traditional underwriting. A greater percentage of mortgage loans purchased pursuant to this program are selected for post-purchase quality control review than for the other program.

Mortgage loans originated through the conduit channel were generally initially underwritten by the seller to the seller’s underwriting guidelines. IndyMac Bank reviews each seller’s guidelines for acceptability, and these guidelines generally meet industry standards and incorporate many of the same factors used by Fannie Mae, Freddie Mac and IndyMac Bank. Each mortgage loan is re-underwritten by IndyMac Bank for compliance with its guidelines based only on the objective characteristics of the mortgage loan, such as FICO, documentation type, loan-to-value ratio, etc., but without reassessing the underwriting procedures originally used. In addition, a portion of the mortgage loans acquired from a seller are subjected to a full re-underwriting.

Exceptions to underwriting standards are permitted in situations in which compensating factors exist. Examples of these factors are significant financial reserves, a low loan-to-value ratio, significant decrease in the borrower’s monthly payment and long-term employment with the same employer.

GMAC Mortgage Corporation Underwriting Guidelines

General

GMAC Mortgage Corporation is a Pennsylvania corporation and a wholly-owned subsidiary of GMAC Residential Holding Corporation, which is a wholly owned subsidiary of Residential Capital Corporation (“ResCap”). ResCap is a wholly-owned subsidiary of GMAC Mortgage Group, Inc., which is a wholly-owned subsidiary of General Motors Acceptance Corporation (“GMAC”). GMAC is a wholly-owned subsidiary of General Motors Corporation.

GMACM began acquiring, originating and servicing residential mortgage loans in 1985 through its acquisition of Colonial Mortgage Service Company, which was formed in 1926, and the loan administration, servicing operations and portfolio of Norwest Mortgage, which entered the residential mortgage loan business in 1906. These businesses formed the original basis of what is now GMACM.

GMACM maintains its executive and principal offices at 100 Witmer Road, Horsham, Pennsylvania 19044. Its telephone number is (215) 682 1000. In addition, GMACM purchases mortgage loans originated by GMAC Bank, which is wholly-owned by ResCap and an affiliate of GMACM. All of the mortgage loans that GMAC Bank originates are originated in accordance with GMACM’s underwriting standards described below. GMAC Bank is a federal savings bank and was formed in 2001.

The diagram below illustrates the ownership structure among the parties affiliated with GMACM.

Loan Origination and Types of Mortgage Loans

GMACM's primary source for residential mortgage loan production is through the origination of loans through its retail branches and direct lending network. GMAC Bank's primary source for residential mortgage loan production is through the origination of loans through its mortgage brokerage network and the purchase of loans in the secondary market (primarily from correspondent lenders).

GMACM originates and acquires mortgage loans that generally fall into one of the following four categories:

Prime Conforming Mortgage Loans — These are prime credit quality first-lien mortgage loans secured by single-family residences that are generally acceptable for purchase by Fannie Mae or Freddie Mac for inclusion in their guaranteed mortgage securities programs.

Prime Non-Conforming Mortgage Loans — These are prime credit quality first-lien mortgage loans secured by single-family residences that either (1) do not conform to the underwriting standards established by Fannie Mae or Freddie Mac, because they have original principal amounts exceeding Fannie Mae and Freddie Mac limits, which are commonly referred to as jumbo mortgage loans, or (2) have alternative documentation requirements and property or credit-related features (e.g., higher loan-to-value or debt-to-income ratios) but are otherwise considered prime credit quality due to other compensating factors.

Government Mortgage Loans — These are first-lien mortgage loans secured by single-family residences that are insured by the Federal Housing Administration or guaranteed by the Veterans Administration.

Second-Lien Mortgage Loans — These are open- and closed-end mortgage loans secured by a second or more junior lien on single-family residences, which include home equity mortgage loans.

The following table summarizes GMACM’s mortgage loan production by type:

Underwriting Standards

General Standards. All mortgage loans that GMACM originates and most of the mortgage loans that GMACM purchases are subject to its underwriting guidelines and loan origination standards. When originating mortgage loans directly through retail branches or by internet or telephone, or indirectly through mortgage brokers, GMACM follows established lending policies and procedures that require consideration of a variety of factors, including:

the borrower’s capacity to repay the loan;

the borrower’s credit history;

the relative size and characteristics of the proposed loan; and

the amount of equity in the borrower’s property (as measured by the borrower’s loan-to-value ratio).

GMACM’s underwriting standards have been designed to produce loans that meet the credit needs and profiles of GMACM borrowers, thereby creating more consistent performance characteristics for investors in GMACM’s loans. When purchasing mortgage loans from correspondent lenders, GMACM either re-underwrites the loan prior to purchase or delegates underwriting responsibility to the correspondent lender originating the mortgage loan.

To further ensure consistency and efficiency, much of GMACM’s underwriting analysis is conducted through the use of automated underwriting technology. GMACM also conducts a variety of quality control procedures and periodic audits to ensure compliance with GMACM origination standards, including responsible lending standards and legal requirements. Although many of these procedures involve manual reviews of loans, GMACM seeks to leverage its technology in further developing our quality control procedures. For example, GMACM has programmed many of its compliance standards into its loan origination systems and continues to use and develop automated compliance technology to mitigate regulatory risk.

GMACM’s underwriting standards with respect to the mortgage loans generally will conform to those published in GMACM’s underwriting guidelines. The underwriting standards as set forth in GMACM’s underwriting guidelines are continually revised based on prevailing conditions in the residential mortgage market and the market for mortgage securities.

The underwriting standards set forth in GMACM’s underwriting guidelines with respect to mortgage loans originated or acquired under GMACM’s jumbo loan programs provide for varying levels of documentation. For the “Standard” documentation loan program, a prospective borrower is required to complete a detailed application providing pertinent credit information. The application contains a description of borrower’s assets and liabilities and a statement of income and expenses, as well as an authorization to apply for a credit report which summarizes the borrower’s credit history with merchants and lenders and any record of bankruptcy. In addition, employment verification is obtained which reports the borrower’s current salary and may contain the length of employment and an indication as to whether it is expected that the borrower will continue such employment in the future. If a prospective borrower is self-employed or if income is received from dividends and interest, rental properties or other income which can be verified from tax returns, the borrower may also be required to submit copies of signed tax returns. In addition, the borrower may be required to authorize verification of deposits at financial institutions where the borrower has accounts.

Loan applications for jumbo loans for loan amounts or combined loan amount less than $850,000 originated or purchased by GMACM may be submitted to an automated underwriting system. GMACM uses Fannie Mae’s Desktop Underwriter program, or DU, or Freddie Mac’s Loan Prospector program, or LP. These automated underwriting systems were developed by Fannie Mae and Freddie Mac and are used to underwrite conventional, governmentally insured and jumbo loans based on established guidelines. Loans that receive an “Approve/Eligible” or an “Approve/Ineligible” only as a result of parameters acceptable under the specific product that do not meet conforming eligibility guidelines in connection with DU or “Accept Plus” or “Accept” in connection with LP are considered loans eligible for origination or purchase by GMACM and may follow reduced income and asset documentation as noted on the automated underwriting finding report. This streamlined documentation alternative does not apply to loan amounts and combined loan amounts exceeding $850,000. Loan amounts and combined loan amounts over $850,000 are not eligible for submission to automated underwriting or the reduced documentation process. The automated underwriting system is not used as a loan decision tool but, instead, is used only as a reduced documentation alternative for certain qualifying mortgage loans, and jumbo loans are generally subjected to a manual review via the approved delegated underwriting authority.

Recently, GMACM has instituted a proprietary automated underwriting decision engine for selected jumbo mortgage products (the “AU Engine”). The proprietary AU Engine is built from Fannie Mae’s Desktop Underwriter program, or DU. Loans must run through the Fannie Mae system to access the AU Engine. Loans that receive an “Approve/Eligible” or an “Approve/Ineligible” from DU will pass through to the AU Engine with the streamlined documentation alternative shown on the report. The AU Engine provides recommendations on GMACM jumbo mortgage products and provides the ability to validate loans using the AU Engine “Approve” recommendation. This automated underwriting decision does not apply to loan amounts and combined loan amounts exceeding $850,000. Loan amounts and combined loan amounts over $850,000 are not eligible for submission to automated underwriting or the reduced documentation process.

The AU Engine delivers a full underwriting decision that includes GMACM’s product guidelines and customized findings messages. Loans that receive an “Approve” recommendation from the AU Engine will be considered as having a GMACM automated conditional approval and will follow the findings documentation report supplied by the AU Engine for all documentation requirements. Loans that receive a “Refer” recommendation from the AU Engine may not follow the findings documentation report requirements. Instead, a full manual underwrite must be completed to validate proper documentation requirements.

In determining the adequacy of the mortgaged property as collateral, an appraisal may be required of each property considered for financing. Such appraisals may be performed by appraisers independent from or affiliated with GMACM or its affiliates. Such appraisals, however, will not establish that the mortgaged properties provide assurance of repayment of the mortgage loans. The appraiser is required to verify that property is in good condition and that construction, if new, has been completed. The appraisal is based on various factors, including the market value of comparable homes and the cost of replacing the improvements. For existing properties, if the appraisal is more than 120 days old but less than 180 days old, the original appraiser must certify that the value has not declined. If the appraisal is more than 180 days old, a new appraisal is required. For new construction or construction-to-permanent loans, if the appraisal is more than 180 days old but less than 360 days old, the original appraiser must certify that the value has not declined. The updated appraisal must be dated within 180 days of the settlement or closing. If the appraisal is more than 360 days old, a new appraisal is required. To the extent that the appraised value of a mortgaged property declines over time, the actual loan-to-value ratio with respect to such mortgage loan will be higher than the loan-to-value ratio derived at the time of origination of such mortgage loan.

Once all applicable employment, credit and property information is received, a determination is made as to whether the prospective borrower has sufficient monthly income available to meet the borrower’s monthly obligations on the proposed mortgage loan and other expenses related to the home (such as property taxes and hazard insurance) and other financial obligations and monthly living expenses.

Under GMACM’s underwriting guidelines, loans may also be originated under the “Relocation” or “Relocation-VIP” documentation programs. Under these programs, certain items described above are verified using alternative sources. In the case of “Relocation” documentation, a signed employer relocation verification form is acceptable in lieu of a paystub. The “Relocation-VIP” program does not require income verification, however, eligible borrowers must have a minimum annual base salary of $75,000.

Loans may also be originated under GMACM’s underwriting guidelines under the “Stated Income” program, a no income verification program for self-employed and salaried borrowers. For these loans, a credit check, an appraisal, and verification of sufficient assets is required. These loans generally will not exceed a 95% loan-to-value ratio on primary residence purchases and rate term refinances and 75% loan-to-value ratio on equity refinances. A 70% loan-to-value ratio on second homes is permitted on purchases and rate term refinances. Equity refinances are not permitted for second homes under the “Stated Income” program

GMACM’s underwriting guidelines also provide for loans under its “Select” program to employees and retirees of General Motors Corporation, or GM. Such loans are made to executives of GM or affiliates of GM, dealer principals and general managers with a minimum annual base salary of $75,000 or to GM or GM affiliate retirees with a minimum base retirement annual income of $60,000. In addition, “Super Select” processed loans are made to executives of GM or affiliates of GM and dealer principals with a minimum annual base salary of $200,000. For both “Select” and “Super Select” loan programs, no income, no asset and, at times, no appraisal is required. Underwriting for “Select” is subject to a maximum loan-to-value ratio of 80% and a combined loan-to-value ratio of 90% for primary and second home purchase and rate term refinance transactions. For the “Select” program, a maximum loan-to-value ratio of 80% is permitted on primary residence equity refinances and a maximum loan-to-value ratio of 70% is permitted for second homes. Underwriting for the “Super Select” program is subject to a maximum loan-to-value ratio of 80% for primary and second home purchase and rate term refinance transactions. No equity refinances are permitted under the “Super Select” loan program. The loan-to-value ratio for the “Super Select” program is based on the borrower’s stated value and generally no appraisal is required for loan-to-value ratios of 80% or less. On the “Select” program, the borrower must supply evidence of value only in some instances. For example, if the combined loan amount exceeds $850,000 or if the loan is an equity refinance loan, an appraisal of the property is required. In addition to the loan-to-value and salary requirements described above, generally, borrower eligibility under the “Select” or “Super Select” documentation program may be determined by use of a credit scoring mode, which in most cases requires a minimum credit score of 680.

The underwriting standards set forth in the GMACM underwriting guidelines may be varied for certain refinance transactions, including “limited documentation” or “reduced documentation” mortgage loan refinances. Limited or reduced documentation refinances, including the programs “Streamline” and “Express,” generally permit fewer supporting documents to be obtained or waive income, appraisal, asset, credit score and employment documentation requirements. Limited or reduced documentation refinances generally compensate for increased credit risk by placing greater emphasis on the borrower’s payment history. Generally, in order to be eligible for a limited or reduced documentation refinance, the borrower must be an existing customer of GMACM, have a good credit history and the mortgage loan must demonstrate other compensating factors, such as a relatively low loan-to-value ratio, stable employment or other favorable underwriting factors.

The underwriting standards set forth in GMACM’s underwriting guidelines may be varied in appropriate cases. There can be no assurance that every mortgage loan was originated in conformity with the applicable underwriting standards in all material respects, or that the quality or performance of the mortgage loans will be equivalent under all circumstances.

GMACM’s underwriting standards include a set of specific criteria pursuant to which the underwriting evaluation is made. However, the application of GMACM’s underwriting standards does not imply that each specific criterion was satisfied individually. Rather, a mortgage loan will be considered to be originated in accordance with a given set of underwriting standards if, based on an overall qualitative evaluation, the loan is in substantial compliance with those underwriting standards. For example, a mortgage loan may be considered to comply with a set of underwriting standards, even if one or more specific criteria included in those underwriting standards were not satisfied, if other factors compensated for the criteria that were not satisfied or if the mortgage loan is considered to be in substantial compliance with the underwriting standards.

Transfer of the Mortgage Loans to the Trustee

The Mortgage Loans will be transferred by the Depositor to the Trustee pursuant to the terms of certain assignment, assumption and recognition agreements, each dated as of February 1, 2006, together with all principal and interest due on the Mortgage Loans after the Cut-Off Date. In connection with such transfer, the Depositor will assign all of its rights and obligations (with the exception of certain obligations) relating to the Mortgage Loans transferred by the Depositor to the Trustee under such agreement. The Trustee will, concurrently with such assignment, execute, and the certificate registrar will authenticate and deliver the certificates. Each Mortgage Loan will be identified in a schedule appearing as an exhibit to the Trust Agreement (the "Mortgage Loan Schedule").

As to each Mortgage Loan (and excepting the MERS loans, as described below), certain documents are required to be delivered to the applicable Custodian, in accordance with the assignment agreements between the Depositor and the Trustee. Such documents generally include the original mortgage note (or, if the original is lost, and if permitted by the related Servicing Agreement, a copy of such mortgage note accompanied by a "lost note affidavit") with applicable addenda and riders, endorsed in blank, without recourse, by the Loan Seller; the original or a certified copy of the mortgage, with evidence of recording thereon, and any required addenda and riders; the original assignment of mortgage and any intervening related assignments, the title insurance policy, the appraisal report and other relevant documentation.

Certain of the Mortgage Loans may have been registered with the Mortgage Electronic Registration System ("MERS"). For these Mortgage Loans, the Custodians will not have original documentation. Instead the Trustee will be registered with MERS as the beneficial owner of such Mortgage Loans.

The Sale Agreements generally provide that if a document that should have been delivered to a Custodian is missing or defective and that defect or missing document materially and adversely affects the value of the related Mortgage Loan, the Loan Seller must deliver the missing document or correct or cure the defect, as applicable. Such Loan Seller must deliver the missing document or cure the defect within 90 days (or 60 days in the case of IndyMac) of notice of the defect or from the original date, as applicable, although, under certain circumstances, the cure period may be extended to 180 days or more from the date the defect is discovered.

The absence of, or the existence of a defect in, an original mortgage note, mortgage or certain other documents may limit the ability of the Servicers to enforce a mortgagor’s obligations under the related Mortgage Loan and to foreclose on defaulted Mortgage Loans. As noted above, if a loss would result from a missing or defective document, the Loan Seller will be obligated to repurchase that Mortgage Loan or to indemnify the Trustee, on behalf of the certificateholders, for any such loss.

Representations and Warranties Regarding the Mortgage Loans

Pursuant to the terms of the related Sale Agreement, each Loan Seller made certain representations and warranties regarding the Mortgage Loans sold by it. In connection with the transfer of the Mortgage Loans to the Trustee, GSMSC, which will acquire the Mortgage Loans from GSMC immediately before they are transferred to the Trustee, will assign to the Trustee on behalf of the certificateholders all of its rights under the Sale Agreements, including the benefit of the representations and warranties therein. The following is a general summary of certain representations and warranties as they appear in such agreements and is not a complete or precise summary of all of the representations and warranties made with respect to the Mortgage Loans. In addition, certain of the representations and warranties set forth below may not have been made with respect to all of the Mortgage Loans. Each of the following representations was made by the related Loan Seller (unless otherwise indicated) as of the date that it sold the related Mortgage Loans:

(i.)

Mortgage Loan Schedule. The information set forth in the Mortgage Loan schedule attached to the applicable agreement is true and correct in all material respects as of the relevant cutoff date;

(ii.)

Payment History. All payments on the Mortgage Loans have been made and credited, there are no material defaults under the terms of the Mortgage Loans and substantially all of the Mortgage Loans have not had a Mortgage Loan payment thirty days or more delinquent more than once in the twelve-month period preceding the Cut-Off Date;

(iii.)

No Outstanding Charges. There are no defaults by the Loan Seller in complying with the terms of the mortgage note or mortgage, and all taxes and government assessments, insurance premiums, water, sewer and municipal charges and leasehold payments or ground rents;

(iv.)

Original Terms Unmodified. The terms of the mortgage note and mortgage have not been impaired, waived, altered or modified in any respect, other than by a written instrument which has been recorded, if necessary and delivered to the purchaser under the related transfer agreement, and any such waiver, alteration or modification has been approved by the mortgage insurer, if the Mortgage Loan is insured, the title insurer if required by the policy and is reflected in the Mortgage Loan schedule to the relevant agreement. No mortgagor has been released in whole or in part, except, with respect to certain of the Mortgage Loans, in connection with an assumption agreement approved by the mortgage insurer or title insurer, as applicable, the terms of which are reflected in the Mortgage Loan schedule to the relevant agreement;

(v.)

No Defenses. The mortgage note and the mortgage are not subject to any right of rescission, set-off, counterclaim or defense (including the defense of usury) as to render such mortgage note or mortgage unenforceable and the mortgagor was not a debtor in any state or federal bankruptcy or insolvency proceeding at the time the Mortgage Loan was originated;

(vi.)

No Satisfaction of Mortgage. The mortgage has not been satisfied, canceled, subordinated, or rescinded, in whole or in part, and the Mortgaged Property has not been released from the lien of the mortgage, in whole or in part;

(vii.)

Validity of Documents. The mortgage note and the related mortgage are genuine and each is the legal, valid and binding obligation of the related mortgagee, enforceable in accordance with its terms, subject to certain bankruptcy and other equitable principles. Such mortgagor had the legal capacity to enter into the Mortgage Loan and execute and deliver the mortgage and mortgage note and the mortgage has been duly executed by such person;

(viii.)

No Fraud. All the documents executed in connection with the Mortgage Loan including, but not limited to, the mortgage note and the Mortgage, are free of fraud and any misrepresentation, are signed by the persons they purport to be signed by, and witnessed or, as appropriate, notarized by the persons whose signatures appear as witnesses or notaries, and each such document constitutes the valid and binding legal obligation of the signatories and is enforceable in accordance with its terms;

THE SPONSOR

The sponsor is Goldman Sachs Mortgage Company, a New York limited partnership ("GSMC" or the "Sponsor"). GSMC is the parent of the Depositor and an affiliate of the underwriter.

GSMC was formed in 1984. Its general partner is Goldman Sachs Real Estate Funding Corp. and its limited partner is The Goldman Sachs Group, Inc. (NYSE:GS). GSMC’s executive offices are located at 85 Broad Street, New York, New York 10004, telephone number (212) 902-1000. GSMC purchases closed, independently funded, first- and subordinate-lien residential mortgage loans for its own investment, securitization, or resale. In addition, GSMC provides warehouse and repurchase financing to mortgage lenders. GSMC does not service loans. Instead GSMC contracts with another entity to service the loans on its behalf. GSMC also may engage in the secondary market activities noted above for non-real estate-secured loans in certain jurisdictions and other activities, but its principal business activity involves real estate-secured assets.

As a sponsor, GSMC acquires residential mortgage loans in the secondary mortgage market and initiates the securitization of the loans it acquires by transferring the mortgage loans to the Depositor, which loans will ultimately be transferred to the issuing entity for the related securitization.

GSMC has been active as a sponsor in the securitization market since 2001. As a sponsor, GSMC acquires residential mortgage loans in the secondary mortgage market and initiates the securitization of the loans it acquires by transferring the mortgage loans to the Depositor, which loans will ultimately be transferred to the issuing entity for the related securitization.

GSMC has been the sponsor of securitizations backed by prime mortgage loans since 2001. The following table describes the approximate volume of prime mortgage loan securitizations sponsored by GSMC since 2001:

Year	Approximate Volume
2001	$0.4 billion
2002	$8.6 billion
2003	$7.8 billion
2004	$10.3 billion
2005	$16.8 billion

GSMC acquires residential mortgage loans in two contexts:

(1)

through bulk purchases, generally consisting of mortgage loan pools greater than $50 million; and

(2)

through conduit purchases.

Prior to acquiring any mortgage loans, GSMC will conduct a review of the related mortgage loan seller. GSMC’s review process consists of reviewing select financial information for credit and risk assessment and underwriting guideline review, senior level management discussion and background checks. The scope of the loan due diligence will depend on the credit quality of the mortgage loans.

The underwriting guideline review considers mortgage loan origination processes and systems. In addition, such review considers corporate policy and procedures relating to HOEPA and state and federal predatory lending, origination practices by jurisdiction, historical loan level loss experience, quality control practices, significant litigation and material investors.

Servicers are assessed based upon review of systems and reporting capabilities (as compared against industry standard), review of collection procedures and confirmation of servicers’ ability to provide loan-level data. In addition, GSMC conducts background checks, meets with senior management to determine whether the servicer complies with industry standards and otherwise monitors the servicer on an ongoing basis.

The Master Servicer shall be required to pay all ordinary expenses incurred by it in connection with its activities as Master Servicer without reimbursement.

The Master Servicer shall pay the costs associated with monitoring the Servicers (including the costs of terminating any Servicer, appointing a successor servicer or the costs of transferring servicing to the Master Servicer) and may be reimbursed therefor by the successor servicer and/or the terminated servicer. To the extent such servicing transfer costs are not paid by the terminated Servicer or the successor servicer, the Master Servicer shall be reimbursed by the Trust Fund for out-of-pocket costs associated with the transfer of servicing of any of the Mortgage Loans from a Servicer to the Master Servicer or to any other successor servicer.

Indemnification and Third Party Claims

The Master Servicer shall indemnify the Depositor, the Securities Administrator and the Trustee and hold each of them harmless against any loss, damages, penalties, fines, forfeitures, legal fees and related costs, judgments, and other costs and expenses resulting from any claim, demand, defense or assertion resulting from, a material breach of the Master Servicer’s representations and warranties set forth in the Trust Agreement. It is understood and agreed that the enforcement of the obligation of the Master Servicer to indemnify the Depositor, the Securities Administrator and the Trustee constitutes the sole remedy of the Depositor, the Securities Administrator and the Trustee in the event of a breach of the Master Servicer’s representations and warranties. Such indemnification shall survive termination of the Master Servicer as Master Servicer under the Trust Agreement and the termination of the Trust Agreement. Any cause of action against the Master Servicer relating to or arising out of the breach of any representations and warranties made by the Master Servicer in the Trust Agreement shall accrue upon discovery of such breach by any of the Depositor, the Master Servicer, the Securities Administrator or the Trustee or notice thereof by any one of such parties to the other parties.

The Master Servicer will indemnify the Depositor, the Securities Administrator and the Trustee, and hold each of them harmless against any and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, liability, fees and expenses that the Depositor or the Trustee may sustain as a result of the Master Servicer’s willful misfeasance, bad faith or negligence in the performance of its duties or by reason of its reckless disregard for its obligations and duties under the Trust Agreement. The Depositor, the Securities Administrator and the Trustee shall promptly notify the Master Servicer if a claim is made by a third party under the Trust Agreement or any of the Mortgage Loans which entitles the Depositor or the Trustee to indemnification by the Master Servicer under the Trust Agreement. The Master Servicer shall assume the defense of any such claim and pay all expenses in connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against it or them in respect of such claim.

The Trust Fund will indemnify the Master Servicer and hold it harmless against any and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, liabilities, fees and unanticipated expenses that the Master Servicer may incur or sustain in connection with, arising out of or related to the Trust Agreement, the Sale and Servicing Agreements, any agreement assigning any of the Sale and Servicing Agreements to the Trust, the custody agreements or the certificates, except to the extent that any such loss, liability or expense is related to (a) a material breach of the Master Servicer’s representations and warranties in the Trust Agreement or (b) the Master Servicer’s willful misfeasance, bad faith or negligence or by reason of its reckless disregard of its duties and obligations under any such agreement. The Master Servicer shall be entitled to reimburse itself for any such indemnified amount from funds on deposit in the Master Servicer Account. Amounts available to pay indemnified costs and expenses may also be applied to reimburse the Master Servicer for servicing transfer costs to the extent such costs are not reimbursed out of amounts allocated therefor or from other sources described in "—Compensation of the Master Servicer" above.

Limitation of Liability of the Master Servicer

Neither the Master Servicer nor any of its directors, officers, employees or agents shall be under any liability to the Trustee or the certificateholders for any action taken, or for refraining from the taking of any action in good faith, or for errors in judgment; provided, however, that the Master Servicer shall remain liable for its willful misfeasance, bad faith or negligence or reckless disregard in the performance of its duties under the Trust Agreement. The Master Servicer shall be under no obligation to appear in, prosecute or defend any legal action that is not incidental to its duties to master service the Mortgage Loans in accordance with the Trust Agreement and that in the opinion of the Master Servicer may subject it to any expenses or liability; provided, however, that the Master Servicer may, in its sole discretion, undertake any such action that it may deem necessary or desirable in respect of the Trust Agreement and the rights and duties of the parties thereto and the interests of the certificateholders thereunder. In the event of any litigation regarding the Master Servicer’s duties, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund.

The Master Servicer shall not be liable for any acts or omissions of any Servicer except to the extent that damages or expenses are incurred as a result of such acts or omissions and such damages and expenses would not have been incurred but for the negligence, willful misfeasance, bad faith or recklessness of the Master Servicer in supervising, monitoring and overseeing the obligations of the Servicers.

Assignment or Delegation of Duties by the Master Servicer; Resignation

The Master Servicer shall not assign or transfer any of its rights, benefits or privileges under the Trust Agreement to any other entity, or delegate to or subcontract with, or authorize or appoint any other entity to perform any of the duties, covenants or obligations to be performed by the Master Servicer without the prior written consent of the Trustee and the Depositor; provided, however, that the Master Servicer shall have the right with the prior written consent of the Trustee, the Securities Administrator and the Depositor (which consents shall not be unreasonably withheld), and upon delivery to the Trustee and the Depositor of a letter from each Rating Agency to the effect that such action shall not result in a downgrade of the ratings assigned to any of the certificates, to delegate or assign to or subcontract with or authorize or appoint any qualified entity to perform and carry out any duties, covenants or obligations to be performed and carried out by the Master Servicer. If the duties of the Master Servicer are transferred to a successor master servicer, the fees and other compensation payable to the Master Servicer under the Trust Agreement shall thereafter be payable to such successor master servicer, but in no event shall such fees and compensation exceed the compensation payable to the predecessor Master Servicer.

Any entity into which the Master Servicer may be merged or consolidated, or any entity resulting from any merger, conversion or other change in form to which the Master Servicer shall be a party, or any entity which succeeds to the business of the Master Servicer, shall be the successor to the Master Servicer, without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided, however, that the successor to the Master Servicer shall be an entity (or an affiliate) that is qualified and approved to service mortgage loans by Fannie Mae and Freddie Mac (provided that if such entity is an affiliate it shall agree to service the Mortgage Loans in accordance with all applicable Fannie Mae and Freddie Mac guidelines) and shall have a net worth of not less than $25,000,000.

The Master Servicer shall not resign unless the Master Servicer’s duties under the Trust Agreement are no longer permissible under applicable law or are in material conflict under applicable law with other activities carried on by it and such conflict cannot be cured. Any resignation of the Master Servicer shall be evidenced by an Opinion of Counsel prepared by counsel to the Master Servicer and delivered to the Securities Administrator, the Trustee and the Depositor. No such resignation shall become effective until the Securities Administrator shall have assumed, or a successor master servicer appointed by the Securities Administrator shall have assumed, the Master Servicer’s responsibilities and obligations under the Trust Agreement.

Master Servicer Events of Default; Waiver; Termination

Under the terms of the Trust Agreement, each of the following shall constitute a "Master Servicer Event of Default" by the Master Servicer: (a) any failure by the Master Servicer to remit to the Securities Administrator any amounts received by it from any Servicer or to make any P&I Advance required to be made by the Master Servicer under the terms of the Trust Agreement, which failure continues unremedied for a period of two (2) Business Days after the date upon which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Securities Administrator or the Trustee; (b) failure by the Master Servicer to duly observe or perform, in any material respect, any other covenants, obligations or agreements of the Master Servicer as set forth in the Trust Agreement, which failure continues unremedied for a period of thirty (30) days after the date on which written notice of such failure, requiring the same to be remedied, shall have been given to the Master Servicer by the Securities Administrator or the Trustee; (c) failure by the Master Servicer to maintain its license to do business in any jurisdiction where the Mortgaged Properties are located, if such license is required; (d) a decree or order of a court or agency or supervisory authority having jurisdiction for the appointment of a conservator or receiver or liquidator in any insolvency, bankruptcy, readjustment of debt, marshaling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer and such decree or order shall have remained in force, undischarged or unstayed for a period of sixty (60) days; (e) the Master Servicer shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, bankruptcy, readjustment of debt, marshaling of assets and liabilities or similar proceedings of or relating to the Master Servicer or relating to all or substantially all of its property; (f) the Master Servicer shall admit in writing its inability to pay its debts as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations for three (3) Business Days; (g) an affiliate of the Master Servicer that performs any duties of the Master Servicer as successor servicer under the Trust Agreement or any servicing duties assumed by the Master Servicer under any Sale and Servicing Agreement ceases to meet the qualifications of a servicer approved by Fannie Mae or Freddie Mac; (h) except as otherwise set forth in the Trust Agreement, the Master Servicer attempts to assign its responsibilities under the Trust Agreement or to delegate its duties thereunder (or any portion thereof), without the consent of the Trustee and the Depositor or (i) the indictment of the Master Servicer for the taking of any action by the Master Servicer, any employee thereof, any affiliate, or any director or employee thereof, that constitutes fraud or criminal activity in the performance of its obligations under the Trust Agreement, in each case, where such action materially and adversely affects the ability of the Master Servicer to perform its obligations under the Trust Agreement (subject to the condition that such indictment is not dismissed within ninety (90) days).

By written notice, the Trustee may waive any default by the Master Servicer in the performance of its obligations under the Trust Agreement and its consequences. Upon any waiver of a past default, such default shall cease to exist, and any Master Servicer Event of Default arising therefrom shall be deemed to have been remedied for every purpose under the Trust Agreement.

So long as a Master Servicer Event of Default remains uncured, the Trustee may, by notice in writing to the Master Servicer, terminate the Master Servicer for cause. Upon any termination of the Master Servicer, it shall prepare, execute and deliver to any successor entity designated by the Securities Administrator or the Trustee, any and all documents and other instruments related to the performance of its duties under the Trust Agreement and, any mortgage files related to any pool of Mortgage Loans with respect to which it acts as a successor servicer in each case, at the Master Servicer’s expense. The Master Servicer shall cooperate with the Securities Administrator and the Trustee and such successor master servicer to effectively transfer its duties under the Trust Agreement.

Reports by the Master Servicer

As set forth in the Trust Agreement, on a date preceding the applicable Distribution Date, each Servicer and the Master Servicer are required to deliver to the Securities Administrator a servicer remittance report setting forth the information necessary for the Securities Administrator to make the distributions set forth under "Description of the Certificates—Distributions of Interest on the Certificates" and "—Distributions of Principal on the Certificates" in this term sheet supplement and containing the information to be included in the distribution report for that Distribution Date delivered by the Securities Administrator. In addition, each Servicer and the Master Servicer will be required to deliver to the Securities Administrator and the Depositor certain monthly reports relating to the Mortgage Loans and the mortgaged properties. The Securities Administrator will provide these monthly reports to certificateholders, at the expense of the requesting certificateholder, who make written requests to receive such information.

Assumption of Master Servicing by Trustee

In the event the Master Servicer is terminated, the Trustee (or its designee) shall assume all of the rights and obligations of the Master Servicer under the Trust Agreement and under each Sale and Servicing Agreement under which the Master Servicer is acting as Servicer, or the Trustee shall appoint a Freddie Mac or Fannie Mae approved servicer that is acceptable to the Depositor and the Rating Agencies. The Trustee, its designee or any successor Master Servicer appointed by the Trustee, shall be deemed to have assumed all of the Master Servicer’s rights, duties and obligations under the Trust Agreement and any Sale and Servicing Agreement pursuant to which the Master Servicer has assumed the duties of the Servicer, to the same extent as if such agreements had been assigned to the Trustee, its designee or any successor master servicer, except that the Master Servicer shall not thereby be relieved of any liability or obligation under the Trust Agreement or any Sale and Servicing Agreement accruing prior to its replacement as Master Servicer, and agrees to indemnify and hold harmless the Trustee (and any successor Master Servicer appointed by the Trustee) from and against all costs, damages, expenses and liabilities (including reasonable attorneys’ fees) incurred by the Trustee (or such successor) as a result of such liability or obligations of the Master Servicer and in connection with the transfer of master servicing and the Trustee’s assumption (but not its performance, except to the extent that costs or liability of the Trustee are created or increased as a result of negligent or wrongful acts or omissions of the Master Servicer prior to its replacement as Master Servicer) of the Master Servicer’s obligations, duties or responsibilities thereunder. To the extent any such costs and expenses are not paid by the Master Servicer, the Trustee may be reimbursed by the Trust for such costs and expenses.

There may be a transition period of not more than 90 days during which the actual transfer of master servicing is effected; provided, however, that neither the terminated Master Servicer nor the Trustee, as applicable, will be relieved of any of its responsibilities under the Trust Agreement during such transition period.

If the Master Servicer has resigned or been terminated, upon request of the Trustee (but at the expense of such Master Servicer), the Master Servicer shall deliver to any successor all documents and records relating to each Sale and Servicing Agreement and the related Mortgage Loans and an accounting of amounts collected and held by it and otherwise use its best efforts to effect the orderly and efficient transfer of each Sale and Servicing Agreement to any successor party.

THE SERVICERS

The Mortgage Loans will initially be serviced by Countrywide Servicing, IndyMac, GMACM and various other mortgage loan servicers (each, a "Servicer" and, collectively, the "Servicers").

It is possible that certain of the Mortgage Loans will be transferred for servicing to one or more other servicers in the future in accordance with the provisions of the Trust Agreement and the related servicing agreement, either because, with respect to the Mortgage Loans acquired through the Conduit Program, the party that owns the related servicing rights (which is currently GSMC) elects to effect such a transfer or, with respect to all of the Mortgage Loans, as a result of the occurrence of unremedied Events of Default (as defined herein). Such servicer or servicers to whom such servicing may be transferred will be acceptable to the Rating Agencies, will have a net worth of at least $25,000,000 and will be a Fannie Mae/Freddie Mac-approved servicer in good standing.

Information relating to the servicing activities of Countrywide Servicing, IndyMac and GMACM is summarized below.

Countrywide Home Loans Servicing LP

The principal executive offices of Countrywide Servicing are located at 7105 Corporate Drive, Plano, Texas 75024. Countrywide Servicing is a Texas limited partnership directly owned by Countrywide GP, Inc. and Countrywide LP, Inc., each a Nevada corporation and a direct wholly owned subsidiary of Countrywide Home Loans, Inc., a New York corporation ("Countrywide Home Loans"). Countrywide GP, Inc. owns a 0.1% interest in Countrywide Servicing and is the general partner. Countrywide LP, Inc. owns a 99.9% interest in Countrywide Servicing and is a limited partner.

Countrywide Home Loans established Countrywide Servicing in February 2000 to service mortgage loans originated by Countrywide Home Loans that would otherwise have been serviced by Countrywide Home Loans. In January and February, 2001, Countrywide Home Loans transferred to Countrywide Servicing all of its rights and obligations relating to mortgage loans serviced on behalf of Freddie Mac and Fannie Mae, respectively. In October 2001, Countrywide Home Loans transferred to Countrywide Servicing all of its rights and obligations relating to the bulk of its non-agency loan servicing portfolio (other than the servicing of home equity lines of credit), including with respect to those mortgage loans (other than home equity lines of credit) formerly serviced by Countrywide Home Loans and securitized by certain of its affiliates. While Countrywide Home Loans expects to continue to directly service a portion of its loan portfolio, it is expected that the servicing rights for most newly originated Countrywide Home Loans mortgage loans will be transferred to Countrywide Servicing upon sale or securitization of the related mortgage loans. Countrywide Servicing is engaged in the business of servicing mortgage loans and will not originate or acquire loans, an activity that will continue to be performed by Countrywide Home Loans. In addition to acquiring mortgage servicing rights from Countrywide Home Loans, it is expected that Countrywide Servicing will service mortgage loans for non-Countrywide Home Loans affiliated parties as well as subservice mortgage loans on behalf of other master servicers.

In connection with the establishment of Countrywide Servicing, certain employees of Countrywide Home Loans became employees of Countrywide Servicing. Countrywide Servicing has engaged Countrywide Home Loans as a subservicer to perform certain loan servicing activities on its behalf.

Countrywide Servicing is an approved mortgage loan servicer for Fannie Mae, Freddie Mac, Ginnie Mae, HUD and VA and is licensed to service mortgage loans in each state where a license is required. Its loan servicing activities are guaranteed by Countrywide Financial and/or Countrywide Home Loans when required by the owner of the mortgage loans.

Countrywide Home Loans

Countrywide Home Loans is a New York corporation and a direct wholly owned subsidiary of Countrywide Financial Corporation, a Delaware corporation ("Countrywide Financial"). The principal executive offices of Countrywide Home Loans are located at 4500 Park Granada, Calabasas, California 91302. Countrywide Home Loans is engaged primarily in the mortgage banking business, and as part of that business, originates, purchases, sells and services mortgage loans. Countrywide Home Loans originates mortgage loans through a retail branch system and through mortgage loan brokers and correspondents nationwide. Mortgage loans originated by Countrywide Home Loans are principally first-lien, fixed or adjustable rate mortgage loans secured by single-family residences.

Except as otherwise indicated, reference in the remainder of this section to "Countrywide Home Loans" should be read to include Countrywide Home Loans and its consolidated subsidiaries, including Countrywide Servicing. Countrywide Home Loans services substantially all of the mortgage loans it originates or acquires. In addition, Countrywide Home Loans has purchased in bulk the rights to service mortgage loans originated by other lenders. Countrywide Home Loans has in the past and may in the future sell to mortgage bankers and other institutions a portion of its portfolio of loan servicing rights. As of September 30, 2005, December 31, 2004, December 31, 2003 and December 31, 2002, Countrywide Home Loans provided servicing for mortgage loans with an aggregate principal balance of approximately $1,047.623 billion, $838.322 billion, $644.855 billion and $452.405 billion, respectively, substantially all of which were being serviced for unaffiliated persons.

Loan Servicing

Countrywide Servicing has established standard policies for the servicing and collection of mortgages. Servicing includes, but is not limited to:

(a)

collecting, aggregating and remitting mortgage loan payments;

(b)

accounting for principal and interest;

(c)

holding escrow (impound) funds for payment of taxes and insurance;

(d)

making inspections as required of the mortgaged properties;

(e)

preparation of tax related information in connection with the mortgage loans;

(f)

supervision of delinquent mortgage loans;

(g)

loss mitigation efforts;

(h)

foreclosure proceedings and, if applicable, the disposition of mortgaged properties; and

(i)

generally administering the mortgage loans, for which it receives servicing fees.

Billing statements with respect to mortgage loans are mailed monthly by Countrywide Servicing. The statement details all debits and credits and specifies the payment due. Notice of changes in the applicable loan rate are provided by Countrywide Servicing to the mortgagor with these statements.

Collection Procedures

When a mortgagor fails to make a payment on a mortgage loan, Countrywide Servicing attempts to cause the deficiency to be cured by corresponding with the mortgagor. In most cases, deficiencies are cured promptly. Pursuant to Countrywide Servicing’s servicing procedures, Countrywide Servicing generally mails to the mortgagor a notice of intent to foreclose after the loan becomes 61 days past due (three payments due but not received) and, generally within 59 days thereafter, if the loan remains delinquent, institutes appropriate legal action to foreclose on the mortgaged property. Foreclosure proceedings may be terminated if the delinquency is cured. Mortgage loans to borrowers in bankruptcy proceedings may be restructured in accordance with law and with a view to maximizing recovery of the loans, including any deficiencies.

Once foreclosure is initiated by Countrywide Servicing, a foreclosure tracking system is used to monitor the progress of the proceedings. The system includes state specific parameters to monitor whether proceedings are progressing within the time frame typical for the state in which the mortgaged property is located. During the foreclosure proceeding, Countrywide Servicing determines the amount of the foreclosure bid and whether to liquidate the mortgage loan.

If foreclosed, the mortgaged property is sold at a public or private sale and may be purchased by Countrywide Servicing. After foreclosure, Countrywide Servicing may liquidate the mortgaged property and charge-off the loan balance which was not recovered through liquidation proceeds.

Servicing and charge-off policies and collection practices with respect to mortgage loans may change over time in accordance with, among other things, Countrywide Servicing’s business judgment, changes in the servicing portfolio and applicable laws and regulations.

Foreclosure, Delinquency and Loss Experience

Historically, a variety of factors, including the appreciation of real estate values, have limited Countrywide Home Loans’ loss and delinquency experience on its portfolio of serviced mortgage loans. There can be no assurance that factors beyond the control of Countrywide Home Loans, such as national or local economic conditions or downturns in the real estate markets of its lending areas, will not result in increased rates of delinquencies and foreclosure losses in the future.

A general deterioration of the real estate market in regions where the mortgaged properties are located may result in increases in delinquencies of loans secured by real estate, slower absorption rates of real estate into the market and lower sales prices for real estate. A general weakening of the economy may result in decreases in the financial strength of borrowers and decreases in the value of collateral serving as security for loans. If the real estate market and economy were to decline, Countrywide Home Loans may experience an increase in delinquencies on the loans it services and higher net losses on liquidated loans.

The following table summarizes the delinquency, foreclosure and loss experience, respectively, on the dates indicated, of the mortgage loans originated or acquired by Countrywide Home Loans, serviced or master serviced by Countrywide Home Loans and securitized by certain affiliates of Countrywide Home Loans in transactions that were registered with the Securities and Exchange Commission. The delinquency, foreclosure and loss percentages may be affected by the size and relative lack of seasoning of the servicing portfolio. Accordingly, the information should not be considered as a basis for assessing the likelihood, amount or severity of delinquency or losses on the mortgage loans and no assurances can be given that the foreclosure, delinquency and loss experience presented in the following table will be indicative of the actual experience on the mortgage loans (totals may not add due to rounding):

IndyMac Bank, F.S.B.

IndyMac Bank will act as Servicer under the Trust Agreement. The principal executive offices of IndyMac are located at 155 North Lake Avenue, Pasadena, California 91101. IndyMac Bank has been master servicing mortgage loans since 1993 and servicing mortgage loans directly (servicing without the use of a subservicer) since 1998. It is expected that on the closing date the servicer will be the only entity servicing the Mortgage Loans. As of the date of this term sheet supplement, IndyMac Bank is rated (x) by Fitch, “RPS2+” as a servicer of alt/A, prime and subprime mortgage loans, (y) by Moody’s, “SQ2” as a primary servicer of prime and subprime first lien mortgage loans and “SQ3” as a special servicer and (z) by S&P, “above average/stable” as a primary servicer and “average/stable” as a master servicer and special servicer.

IndyMac will be responsible for servicing the Mortgage Loans in accordance with the terms set forth in the related servicing agreement employing the same degree of skill and care that it employs in servicing other mortgage loans comparable to the Mortgage Loans serviced by IndyMac for itself or others. The Servicer has agreed to represent and protect the interest of the trustee in the Mortgage Loans in the same manner as it currently protects its own interest in mortgage loans in its own portfolio in any claim, proceeding or litigation regarding a Mortgage Loan.

If the servicing of any Mortgage Loan were to be transferred from a subservicer to IndyMac, or if any other servicing transfer were to occur, there may be an increase in delinquencies and defaults due to misapplied or lost payments, data input errors, system incompatibilities or otherwise. Although any increase in delinquencies is expected to be temporary, there can be no assurance as to the duration or severity of any disruption in servicing the applicable Mortgage Loans as a result of any servicing transfer. See also “Risk Factors—Bankruptcy or Insolvency May Affect the Timing and Amount of Distributions on the Certificates” in the prospectus.

Foreclosure, Delinquency and Loss Experience

The delinquency, foreclosure and loss percentages set forth in the tables below may be affected by the size and relative lack of seasoning of the master servicing and servicing portfolio. Delinquencies, foreclosures and losses generally are expected to occur more frequently after the first full year of the life of mortgage loans. Accordingly, because a large number of mortgage loans serviced by IndyMac have been recently originated, the current level of delinquencies, foreclosures and losses may not be representative of the levels that may be experienced over the lives of such mortgage loans. If the volume of IndyMac Bank’s new loan originations and acquisitions declines, the levels of delinquencies, foreclosures and losses as percentages of the portfolio could rise significantly above the rates indicated in the tables.

GMAC Mortgage Corporation – Servicing Activities

Servicing Activities

GMACM generally retains the servicing rights with respect to loans it sells or securitizes, and also occasionally purchases mortgage servicing rights from other servicers or acts as a subservicer of mortgage loans (and does not hold the corresponding mortgage servicing right asset). The following table sets forth the types of residential mortgage loans comprising GMACM’s primary servicing portfolio for which GMACM holds the corresponding mortgage servicing rights:

GMAC MORTGAGE CORPORATION PRIMARY SERVICING PORTFOLIO FOR WHICH GMACM HOLDS THE CORRESPONDING SERVICING RIGHTS ($ IN MILLIONS)

As of December 31, 2004, GMACM acted as primary servicer and owned the corresponding servicing rights on approximately 2 million of residential mortgage loans having an aggregate unpaid principal balance of $218 billion, and GMACM acted as subservicer (and did not own the corresponding servicing rights) on approximately 99,082 loans having an aggregate unpaid principal balance of over $13.9 billion.

For current static pool data with respect to mortgage loans serviced by GMACM, see "Static Pool Information" (such data, as it relates to GMACM, for the purposes of this section, "Static Pool Data").

As used in the Static Pool Data, a loan is considered to be "30 to 59 days" or "30 or more days" delinquent when a payment due on any due date remains unpaid as of the close of business on the last business day immediately prior to the next following monthly due date. The determination as to whether a loan falls into this category is made as of the close of business on the last business day of each month. Grace periods and partial payments do not affect these determinations.

Charge offs are taken only when GMACM has determined that it has received all payments or cash recoveries which GMACM reasonably and in good faith expects to be finally recoverable with respect to any mortgage loan.

There can be no assurance that the delinquency and foreclosure experience set forth in the Static Pool Data will be representative of the results that may be experienced with respect to the mortgage loans included in the trust.

As servicer, GMACM collects and remits mortgage loan payments, responds to borrower inquiries, accounts for principal and interest, holds custodial and escrow funds for payment of property taxes and insurance premiums, counsels or otherwise works with delinquent borrowers, supervises foreclosures and property dispositions and generally administers the loans. GMAC may, from time to time, outsource certain of its servicing functions, such as contacting delinquent borrowers, protecting tax administration and hazard insurance administration, although any such outsourcing will not relieve GMACM of any of its responsibilities or liabilities as servicer.

Servicing Compensation and the Payment of Expenses

A servicing fee (the "Servicing Fee") for each Mortgage Loan will be payable to each Servicer at a per annum rate generally equal to 0.20% to 0.25% of the scheduled principal balance of each Mortgage Loan such Servicer services. The right of each Servicer to receive Servicing Fees or other compensation (to the extent actually collected), or for the reimbursement of Advances, is senior to the rights of certificateholders. Each Servicer is entitled to retain as additional servicing compensation certain ancillary fees, such as assumption fees and late fees, to the extent that such fees are collected from mortgagors and exceed any other amounts due and payable on the related Mortgage Loan, and any interest or other income earned on funds held in the related Collection Account.

Collection and Other Servicing Procedures

The Sale and Servicing Agreements generally require that the related Servicer proceed diligently to collect all payments called for under the mortgage loans serviced by it, consistent with such Servicing Agreement, and with respect to each Mortgage Loan in substance to follow servicing practices it customarily employs and exercises in servicing and administrating mortgage loans for its own account and which are generally consistent with Fannie Mae standards and accepted servicing practices of prudent mortgage lending institutions that service mortgage loans of the same type as the mortgage loans serviced by it.

The various mortgagors are generally required to make monthly payments to the Servicers of principal and interest due on the Mortgage Loans (each, a "Scheduled Payment. Each Servicer will be required to deposit in a Collection Account, generally no later than the second Business Day following receipt, all Scheduled Payments collected on the Mortgage Loans and any Advances. Each Sale and Servicing Agreement requires that such funds be held in a time deposit or demand account with a depositary institution the long-term unsecured debt ratings of which are rated in the two highest ratings categories of one or more of S&P, Moody’s or Fitch.

Pursuant to each Sale and Servicing Agreement, the related Servicer will establish and maintain accounts (each, an "Escrow Account") into which certain mortgagors will be required to deposit amounts sufficient to pay taxes, assessments, standard hazard insurance premiums, and other comparable items. Withdrawals from an Escrow Account maintained for mortgagors may be made to effect timely payment of taxes, assessments, or comparable items, to reimburse the related Servicer for any Advances made with respect to a Mortgage Loan (but only from amounts received on such Mortgage Loan which represent late collections of escrowed amounts thereunder), to refund to mortgagors amounts determined to be overages, to pay interest on balances in such Escrow Account to such Servicer, or if required by law, to the related mortgagors, to repair or otherwise protect the related Mortgaged Property and to clear and terminate such account. Each Servicer will be responsible for the administration of the Escrow Accounts maintained by it and will generally be obligated to make advances to such accounts when a deficiency exists in such accounts.

Maintenance of Insurance Policies; Claims Thereunder and Other Realization upon Defaulted Mortgage Loans

Each Servicer will cause to be maintained for each Mortgage Loan serviced by it hazard insurance such that all buildings upon the Mortgaged Property are insured, generally by an insurer acceptable to Fannie Mae or Freddie Mac against loss by fire and hazards, with extended coverage customary in the area where the Mortgaged Property is located. The insurance amount must be at least equal to the lesser of (i) the maximum insurable value of the improvements securing such Mortgage Loan and (ii) the greater of (a) the outstanding principal balance of the Mortgage Loan and (b) an amount such that the proceeds thereof shall be sufficient to prevent the mortgagor or the loss payee from becoming a co-insurer. Generally, if a hazard insurance policy shall be in danger of being terminated, or if the insurer shall cease to be acceptable, the Servicer shall notify the related mortgagor, and the Trustee, and shall use its best efforts, as permitted by applicable law, to cause the mortgagor to obtain from another qualified insurer a replacement hazard insurance policy substantially and materially similar in all respects to the original policy. In no event, however, shall a Mortgage Loan be without a hazard insurance policy at any time.

If upon origination of the Mortgage Loan, the related Mortgaged Property was located in an area identified by the Flood Emergency Management Agency as having special flood hazards (and such flood insurance has been made available) a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration is in effect with an insurance carrier acceptable to Fannie Mae or Freddie Mac equal to the lesser of (i) the minimum amount required, under the terms of coverage, to compensate for any damage or loss on a replacement cost basis (or the unpaid balance of the Mortgage Loan if replacement cost coverage is not available for the type of building insured) and (ii) the maximum amount of insurance which is available under the Flood Disaster Protection Act of 1973, as amended.

If a mortgage is secured by a unit in a condominium project, the Servicer shall verify that the coverage required of the owner's association, including hazard, flood, liability, and fidelity coverage, is being maintained in accordance with then current federal requirements, and secure from the owner's association its agreement to notify such Servicer promptly of any change in the insurance coverage or of any condemnation or casualty loss that may have a material affect on the value of the Mortgaged Property as security.

Each Servicer is required to maintain hazard and flood insurance on REO property (i.e., real property acquired following foreclosure as to which a realized loss has not yet been taken) related to Mortgage Loans serviced by it similar to the insurance required above, as well as liability insurance. A Servicer may satisfy its obligation to cause the foregoing insurance to be maintained by obtaining a blanket policy on all of the Mortgage Loans, which policy satisfied the requirements set forth above.

All policies are required to name the related Servicer as loss payee and shall be endorsed with standard or union mortgagee clauses, without contribution, which shall provide for at least 30 days' prior written notice of any cancellation, reduction in amount or material change in coverage.

Evidence as to Servicing Compliance

During or prior to March of each year, commencing with March 2007, each Servicer and the Master Servicer will be required to deliver to the Depositor an officer’s certificate stating that (i) a review of that party’s servicing activities during the preceding calendar year and of its performance under the Trust Agreement has been made under the supervision of the officer, and (ii) to the best of the officer’s knowledge, based on the review, such party has fulfilled all its obligations under the Trust Agreement in all material respects throughout the year, or, if there has been a failure to fulfill any such obligation in any material respect, specifying such failure known to the officer and the nature and status thereof.

In addition, during or prior to March of each year, commencing with March 2007, each party that participates in the servicing and administration of more than 5% of the Mortgage Loans and any other assets of the Trust Fund (including, without limitation, the Securities Administrator, the Master Servicer, each Custodian and each Servicer) will be required to deliver annually to the Depositor and/or the Securities Administrator, as applicable, a report (an "Assessment of Compliance") that assesses compliance by that party with the servicing criteria set forth in Item 1122(d) of Regulation AB (17 CFR 229.1122) applicable to such party that contains the following:

(a)

a statement of the party’s responsibility for assessing compliance with the servicing criteria applicable to it;

(b)

a statement that the party used the criteria in Item 1122(d) of Regulation AB to assess compliance with the applicable servicing criteria;

(c)

the party’s assessment of compliance with the applicable servicing criteria as of and for the period ending the end of the prior calendar year, setting forth any material instance of noncompliance identified by the party; and

(d)

a statement that a registered public accounting firm has issued an attestation report on the party’s assessment of compliance with the applicable servicing criteria as of and for the period ending the end of the prior calendar year.

Each party that is required to deliver an Assessment of Compliance will also be required to simultaneously deliver a report (an "Attestation Report") of a registered public accounting firm, prepared in accordance with the standards for attestation engagements issued or adopted by the Public Company Accounting Oversight Board, that expresses an opinion, or states that an opinion cannot be expressed, concerning the party’s assessment of compliance with the applicable servicing criteria.

Fidelity bonds and errors and omissions policies are also required to be maintained by each Servicer under the applicable Sale and Servicing Agreement.

Servicer Events of Default

Events of default ("Events of Default") under each Sale and Servicing Agreement will generally consist of:

(1)

any failure by the Servicer to make any remittances or deposits required under such Servicing Agreement, which failure continues unremedied for the period specified in such Servicing Agreement, after the date the Master Servicer or the Trustee has given written notice of such failure to the Servicer;

(2)

any failure by the Servicer to observe or perform in any material respect any covenant or agreement by the Servicer in the Sale and Servicing Agreement or in the related custodial agreement, if applicable, which failure continues unremedied for a period of 60 days, or in some cases 30 days after written notice of the failure, requiring the same to be remedied by the Servicer has been given (or, in some cases, caused to be given) by the Master Servicer, the Trustee or the applicable Custodian, in some cases, or received by the Servicer, in other cases;

(3)

failure by the Servicer to maintain its license to do business or service residential mortgage loans in any jurisdiction where a Mortgaged Property related to a mortgage loan serviced by it is located;

(4)

certain events relating to insolvency, readjustment of debt, marshaling of assets and liabilities or similar proceedings to the extent not discharged or stayed within 60 days or in some cases 30 days and certain actions by or on behalf of the Servicer indicating its insolvency;

(5)

the Servicer admits in writing its inability to pay its obligations as they become due;

(6)

the Servicer ceases to qualify as a Fannie Mae or Freddie Mac approved servicer; and

(7)

the Servicer without consent of the mortgage owner attempts to assign the Sale and Servicing Agreement or its servicing responsibilities or to delegate its duties thereunder or any portion thereof.

Certain of the Events of Default described above may not apply to all of the Mortgage Loans.

Rights upon Events of Default

So long as an Event of Default under a Sale and Servicing Agreement as described in the preceding paragraph remains unremedied after the lapse of any applicable grace period, the Master Servicer may, and at the direction of holders of certificates evidencing not less than 66% of the voting rights of the certificates shall, by notice in writing to the related Servicer, terminate all of the rights and obligations of such Servicer, in its capacity as Servicer, under the Sale and Servicing Agreement. Upon receipt by a Servicer of notice of termination, the Master Servicer will appoint a successor servicer acceptable to the Master Servicer and the Securities Administrator and such successor servicer shall succeed to all the responsibilities, duties and liabilities of such Servicer under the Sale and Servicing Agreement (other than any obligation to repurchase any Mortgage Loan) and will be entitled to similar compensation arrangements. There may be a transition period of not more than 90 days during which the actual transfer of servicing is effected; provided, however, that neither the Master Servicer nor the applicable terminated Servicer will be relieved of any of its responsibilities under the applicable Servicing Agreement or the Trust Agreement during such transition period. In the event the Master Servicer is unable to timely appoint a successor servicer, or if the holders of certificates evidencing not less than 51% of the voting rights request in writing, the Trustee shall appoint or petition a court of competent jurisdiction for the appointment of a mortgage loan servicing institution, with a net worth of at least $25,000,000 to act as successor to the Servicer under such Servicing Agreement. Pending such appointment, the Trustee is obligated to act in such capacity. The Master Servicer and such successor may agree upon the servicing compensation to be paid, which in no event may be greater than the compensation to the terminated Servicer under such Servicing Agreement. In addition, holders of certificates evidencing at least 66% of the voting rights of certificates affected by an Event of Default may waive such Event of Default; provided, however, that (a) an Event of Default with respect to the Servicer's obligation to make Servicing Advances or P&I Advances may be waived only by all of the holders of certificates affected by such Event of Default, and (b) no such waiver is permitted that would have a material adverse affect on any non-consenting holder of certificate(s).

Certain Matters Regarding the Servicers

Generally, a Servicer may not assign its Servicing Agreement or the servicing thereunder, or delegate its rights or duties thereunder or any portion thereof, nor sell or otherwise dispose of all or substantially all of its property or assets without the prior written consent of the Securities Administrator, the Trustee and the Master Servicer, which consent will not be unreasonably withheld. The respective obligations and responsibilities of a Servicer under the related Servicing Agreement may be terminated by mutual consent of that Servicer and the Master Servicer in writing.

Generally, a Servicer may not resign from its obligations and duties imposed on it by its Sale and Servicing Agreement except (i) by mutual consent of such Servicer, the Securities Administrator, the Trustee and the Master Servicer or (ii) in certain cases, upon the determination that its duties thereunder are no longer permissible under applicable law and such incapacity cannot be cured by such Servicer. Generally, any such determination permitting the resignation of a Servicer shall be evidenced by an opinion of counsel to such effect delivered to the Securities Administrator, the Trustee and the Master Servicer which opinion of counsel shall be in form and substance acceptable to the Securities Administrator, the Trustee and the Master Servicer. No resignation of a Servicer shall become effective until a successor shall have assumed the Servicer's responsibilities and obligations in the manner provided in the related Servicing Agreement.

Generally, the Sale and Servicing Agreements provide that any company into which a Servicer is merged or consolidated will succeed automatically to the duties of such Servicer, provided that such entity is a Fannie Mae/Freddie Mac approved servicer and provided, further, that such entity has the minimum net worth specified in the related Servicing Agreement, such entity is an institution whose deposits are insured by FDIC or a company whose business includes the origination and servicing of mortgage loans.

Without in any way limiting the generality of the foregoing, and except in the case of certain mergers, if a Servicer either assigns the Sale and Servicing Agreement or the servicing responsibilities thereunder or delegates its duties thereunder or any portion thereof or sells or otherwise disposes of all or substantially all of its property or assets, without the prior written consent of the Master Servicer, then the Master Servicer will generally have the right to terminate the related Servicing Agreement upon notice, without any payment of any penalty or damages and without any liability whatsoever to the Servicer or any third party.

The Master Servicer may, and upon the direction of holders of certificates evidencing no less than 66% of the voting rights of the certificates shall, terminate a Servicer without cause, subject to payment as liquidated damages of any termination fee set forth in the related Servicing Agreement. Notwithstanding the foregoing, the Master Servicer may not terminate a Servicer without cause unless a successor servicer is appointed concurrently with such termination, and such successor servicer (or a third party on its behalf) pays such Servicer any amounts specified in the related Servicing Agreement. Any successor servicer appointed to service the related Mortgage Loans following such a termination shall be an established mortgage loan servicing institution, must be reasonably acceptable to the Master Servicer, must be acceptable to each Rating Agency for purposes of maintaining its then-current ratings of the certificates, and must comply with any further requirements under the related Servicing Agreement.

The Sale and Servicing Agreements generally provide that neither the related Servicer thereunder nor any of the directors, officers, employees or agents of such Servicer shall be under any liability to the Trustee for any action taken or for refraining from the taking of any action in good faith pursuant to such Servicing Agreement, or for errors in judgment; provided, however, that this provision shall not protect such Servicer or any such person against any breach of warranties or representations made in such Servicing Agreement, or failure to perform its obligations in strict compliance with any standard of care set forth in such agreement or any other liability which would otherwise be imposed under such agreement. The Servicers are generally not under any obligation to appear in, prosecute or defend any legal action which is not incidental to their respective duties to service the mortgage loans in accordance with the related Servicing Agreement and which in its opinion may involve it in any expense or liability; provided, however, that in some cases, a Servicer may, with the consent of the Master Servicer, undertake any such action which it deems necessary or desirable in respect of the related Servicing Agreement and the rights and duties of the parties thereto. In such event, such Servicer shall be entitled to reimbursement from the assets of the Trust Fund of the reasonable legal expenses and costs of such action as provided in the related Servicing Agreement.

With respect to the applicable Sale and Servicing Agreement, the Trust Fund will generally indemnify and hold harmless the applicable Servicer against any and all losses that it may sustain as a result of any act or omission on the part of the Trust Fund.

DESCRIPTION OF THE CERTIFICATES

General

The certificates will be issued pursuant to the Trust Agreement. A form of the Trust Agreement is filed as an exhibit to the registration statement of which this term sheet supplement is a part. The prospectus contains important additional information regarding the terms and conditions of the Trust Agreement and the certificates. The Senior Certificates will not be issued unless they receive the ratings from one or more of Standard & Poor’s Ratings Group, a division of The McGraw Hill Companies, Inc. ("S&P"), Moody’s Investors Service, Inc. ("Moody’s") and Fitch Ratings ("Fitch," and each of S&P, Moody’s and Fitch, a "Rating Agency"), indicated in the term sheet. The Senior Subordinate Certificates will not be issued unless they receive the ratings from S&P indicated in the term sheet. If so indicated in the term sheet, as of February 24, 2006 (the "Closing Date"), the offered certificates, other than the Class 1B-2, Class 1B-3, Class 2B-2 and Class 2B-3 Certificates, are expected to qualify as "mortgage related securities" within the meaning of the Secondary Mortgage Market Enhancement Act of 1984, as amended.

Only the Senior Certificates and the Senior Subordinate Certificates, referred to as the offered certificates, are offered by this term sheet supplement. The Junior Subordinate Certificates, Class X Certificates and the Residual Certificates are not offered hereby.

Collectively, the certificates will represent the entire beneficial ownership interest in the Trust Fund, legal title to which will be held by the Trustee. Each class of certificates will relate to one or more Collateral Groups of Mortgage Loans.

The Senior Certificates related to each Collateral Group, along with the related Group Subordinate Amounts of each Collateral Group, are sometimes referred to separately as a "Certificate Group."

Each class of offered certificates will be issued in the respective approximate initial Class Principal Balance to be specified in the term sheet or total Notional Amount to be described therein. The initial aggregate Certificate Principal Balance or aggregate Notional Amount (as defined herein) of all the certificates may be increased or decreased by up to five percent to the extent that the aggregate scheduled principal balance of the Mortgage Loans as of the Cut-Off Date is increased or decreased as described under "Description of the Mortgage Pool" herein.

The "Certificate Balance" for any Distribution Date and for any certificate, other than any Interest Only Certificate, will equal the aggregate amount of principal to which it is entitled on the Closing Date, reduced by all distributions of principal to such certificate, and all allocations of losses on such certificate before such Distribution Date.

The "Class Principal Balance" of any class of certificates on any Distribution Date will be equal to the total Certificate Balance of all Certificates of such class on that Distribution Date.

Distributions on the certificates will be made on the 25^th day of each month or, if the 25^th day is not a Business Day, on the next succeeding Business Day, beginning in March 2006 (each, a "Distribution Date"), to certificateholders of record on the applicable Record Date. The "Record Date" for the offered certificates and each Distribution Date will be the last Business Day of the related Interest Accrual Period.

Exchangeable Certificates

General

All or a portion of certain classes of offered certificates may be exchanged for a proportionate interest in the related Exchangeable Certificates in the combinations to be shown in the prospectus supplement. All or a portion of the Exchangeable Certificates may also be exchanged for the related offered certificates in the same manner. This process may occur repeatedly.

The classes of offered certificates and of Exchangeable Certificates that are outstanding at any given time, and the outstanding principal balances and notional amounts of these classes, will depend upon any related distributions of principal, as well as any exchanges that occur. Offered certificates and Exchangeable Certificates in any combination may be exchanged only in the proportion that the original principal balances of such certificates bear to one another to be shown in the prospectus supplement.

Holders of Exchangeable Certificates will be the beneficial owners of a proportionate interest in the certificates in the related Combination Group and will receive a proportionate share of the distributions on those certificates.

Procedures

If a Certificateholder wishes to exchange certificates, the Certificateholder must notify the Securities Administrator by e-mail at sherri.j.sharps@wellsfargo.com or sean.ralston@wellsfargo.com no later than two Business Days before the proposed exchange date. The exchange date can be any Business Day other than the first or last Business Day of the month subject to the Securities Administrator’s approval. The notice must be on the Certificateholder’s letterhead, carry a medallion stamp guarantee and set forth the following information: the CUSIP number of both certificates to be exchanged and certificates to be received, outstanding principal balance and/or notional amount and the original principal balance and/or notional amount of the certificates to be exchanged, the Certificateholder’s DTC participant number and the proposed exchange date. After receiving the notice, the Securities Administrator will e-mail the Certificateholder with wire payment instructions relating to the exchange fee. The Certificateholder will utilize the Deposit and Withdrawal System at DTC to exchange the Certificates. A notice becomes irrevocable on the second Business Day before the proposed exchange date.

In connection with each exchange, the Certificateholder must pay the Securities Administrator a fee equal to 1/32 of 1% of the outstanding principal balance (or the notional amount, if no principal balance) of the certificates to be exchanged. In no event, however, will the fee be either less than $2,000 or greater than $25,000.

The Securities Administrator will make the first distribution on an offered certificate or an Exchangeable Certificate received in an exchange transaction on the Distribution Date in the following month to the Certificateholder of record as of the close of business on the last day of the month of the exchange.

Additional Considerations

The characteristics of the Exchangeable Certificates will reflect the characteristics of the related offered certificates. Investors are encouraged to also consider a number of factors that will limit a Certificateholder’s ability to exchange offered certificates for Exchangeable Certificates and vice versa:

At the time of the proposed exchange, a Certificateholder must own certificates of the related class or classes in the proportions necessary to make the desired exchange.

A Certificateholder that does not own the certificates may be unable to obtain the necessary offered certificates or Exchangeable Certificates.

The Certificateholder of needed certificates may refuse to sell them at a reasonable price (or any price) or may be unable to sell them.

Certain certificates may have been purchased or placed into other financial structures and thus be unavailable.

Principal distributions will decrease the amounts available for exchange over time.

Only the combinations to be listed in the prospectus supplement are permitted.

Distributions of Interest on the Certificates

Each of the Mortgage Pass-Through Certificates, Series 2006-2F will bear interest (except in the case of each class of Principal Only Certificates, which do not bear interest, and the Subordinate Certificates) at the rates per annum (each, a "Certificate Interest Rate") to be set forth or described in the term sheet. The "Certificate Interest Rate" for the Subordinate Certificates for each Accrual Period will be an annual rate equal to the weighted average of the Designated Rates applicable to each of the related Collateral Groups, weighted on the basis of the related Group Subordinate Amount for each such Collateral Group.

Interest accrued on any class of certificates will be reduced for each Collateral Group by the pro rata share allocated to such class of all interest shortfalls resulting from (i) Payoffs and Curtailments of the Mortgage Loans contributing to such Collateral Group during the preceding calendar month, to the extent not covered by Compensating Interest, and (ii) reductions in interest payable on the Mortgage Loans contributing to such Collateral Group by operation of law (such shortfalls are allocated among all classes pro rata in proportion to the amount of interest to which such class would otherwise be entitled).

The Accrued Certificate Interest payable to each class of certificates will include unpaid interest from prior Distribution Dates (without interest on such overdue interest), but will only be paid to the extent of the related Available Distribution Amount.

The "Basis Risk Shortfalls" for any class of certificates will equal the excess, if any, of the amount of interest that class would have been entitled to receive if the Certificate Interest Rate for such class were calculated without regard to the related maximum rate, over the actual amount of interest such class is entitled to receive for such Distribution Date.

Pursuant to the terms of the Trust Agreement, the Securities Administrator may establish a separate account (the "Basis Risk Reserve Fund"). Any Basis Risk Reserve Fund will not be an asset of any REMIC, nor will it be an asset of the Trust Fund. Any Basis Risk Reserve Fund will instead be held in a separate interest trust for the benefit of the holders of the related class or classes of LIBOR Certificates and the Class X Certificates. After Interest Rate Cap Amounts (as defined below) have been applied to reduce any Basis Risk Shortfalls on the related class or classes of LIBOR Certificates as described herein, amounts in any Basis Risk Reserve Fund will be used to make payments to the Holders of the related class or classes of LIBOR Certificates with respect to any unpaid Basis Risk Shortfalls on such certificates from prior Distribution Dates.

On any Distribution Date for which an unpaid Basis Risk Shortfall exists on the related class or classes of LIBOR Certificates, the Securities Administrator will withdraw from any Basis Risk Reserve Fund an amount equal to the lesser of (i) the amount of such unpaid Basis Risk Shortfalls for such Distribution Date and (ii) the balance in any Basis Risk Reserve Fund on such Distribution Date, and distribute such amount to the related class or classes of LIBOR Certificates.

Upon the earlier to occur of (i) the Distribution Date on which the Class Principal Balance of the Cap Contract Certificates is reduced to zero and (ii) the optional purchase of the related Mortgage Loans, any amounts remaining in any Basis Risk Reserve Fund will be distributed to the Class X Certificates.

The Interest Rate Cap

On the Closing Date, Wells Fargo Bank N.A., as Securities Administrator, on behalf of U.S. Bank National Association, as the trustee of a separate interest trust created pursuant to the Trust Agreement, may be assigned an interest rate cap agreement on behalf of the related class or classes of LIBOR Certificates and Class X Certificateholders (the "Interest Rate Cap").

Any Interest Rate Cap will provide for a "Strike Price" to be designated in the prospectus supplement and a Projected Principal Balance for each Distribution Date. The "Projected Principal Balances" with respect to the Interest Rate Cap for each applicable Distribution Date will be set forth in the prospectus supplement. The Projected Principal Balances for the Interest Rate Cap have been calculated assuming a prepayment rate on the Mortgage Loans contributing to Collateral Group 3 as designated in the prospectus supplement. We can give you no assurance that the Mortgage Loans contributing to the related Collateral Group will prepay at that rate or at any other rate.

With respect to each Distribution Date, the Interest Rate Cap will, if LIBOR exceeds the Strike Price, provide for the payment to the Securities Administrator of an amount equal to the product of (i) one-twelfth and (ii) the excess, if any, of LIBOR for such Distribution Date (up to a maximum rate to be designated in the prospectus supplement) over the Strike Price and (iii) an amount equal to the Projected Principal Balance for such Distribution Date (each such payment, an "Interest Rate Cap Amount").

On any Distribution Date, Interest Rate Cap Amounts paid by the Interest Rate Cap Provider to the Securities Administrator will be available to make distributions on behalf of the separate interest trust for distribution in the following order of priority:

first, (a) to the related class or classes of certificates, to pay Basis Risk Shortfalls on such certificates for such Distribution Date up to an amount equal to the product of (i) one-twelfth and (ii) the excess, if any, of LIBOR for such Distribution Date (up to the maximum rate) over the Strike Price and (iii) the lesser of (x) an amount equal to the Projected Principal Balance for such Distribution Date and (y) the Certificate Principal Balance of each related class of certificates for such Distribution Date;

second, to the related class or classes of certificates to pay Basis Risk Shortfalls on such certificates remaining unpaid from prior Distribution Dates; and

third, the remainder for deposit into any Basis Risk Reserve Fund in an amount at least equal to the applicable Required Reserve Fund Deposit.

It is intended that payments under the Interest Rate Cap provide protection against upward movements in LIBOR and diminish the basis risk to the related class or classes of certificates associated with the Trust Fund’s investment in the Mortgage Loans paying interest at a fixed rate. See "Description of the Mortgage Pool." However, there can be no assurance that amounts payable under the Interest Rate Cap will be sufficient to cover such shortfalls.

Any Interest Rate Cap will be terminable by the separate interest trust or the Interest Rate Cap Provider following the occurrence of certain specified events of default, including failure of the Interest Rate Cap Provider to make required payments, and certain standard events under the 1992 International Swaps and Derivatives Association, Inc. Master Swap Agreement (Multi-Cross-Border).

Interest Rate Cap Provider

The "Interest Rate Cap Provider"), will be designated in the prospectus supplement. The Interest Rate Cap Provider will provide upon request, without charge, to each person to whom this term sheet supplement is delivered, a copy of (i) the ratings analysis from S&P, Moody’s and/or Fitch evidencing any ratings on the Interest Rate Cap Provider or (ii) the most recent audited annual financial statements of the Interest Rate Cap Provider. Requests for such information should be directed to the Depositor.

The Class X Certificate

The Class X Certificate represents the right to receive certain amounts on deposit in any Basis Risk Reserve Fund on the earlier to occur of (i) the Distribution Date on which the aggregate Certificate Principal Balance of the related class or classes of certificates is reduced to zero and (ii) the optional purchase of the Mortgage Loans.

Determination of LIBOR

Certain classes of certificates may be floating rate certificates (the "LIBOR Certificates") that bear interest either at a rate based on LIBOR plus a margin or which vary inversely with LIBOR, in each case subject to the minimum and maximum rates to be described in the prospectus supplement. These certificates are also referred to as "Floating Rate Certificates."

"LIBOR" means, for any Interest Accrual Period (other than the initial Interest Accrual Period), the offered rate for one-month United States dollar deposits which appears on Telerate Page 3750, as reported by Bloomberg Financial Markets Commodities News (or such other page as may replace Telerate Page 3750 for the purpose of displaying comparable rates), as of 11:00 a.m. (London time) on the LIBOR Determination Date applicable to such Interest Accrual Period. If such rate does not appear on Telerate Page 3750 (or such other page as may replace Telerate Page 3750 for the purpose of displaying comparable rates), the rate for that day will be determined on the basis of the rates at which deposits in United States dollars are offered by the Reference Banks at approximately 11:00 a.m., London time, on that day to leading banks in the London interbank market for a period of one month commencing on the first day of the relevant Interest Accrual Period. The Securities Administrator will request the principal London office of each of the Reference Banks to provide a quotation of its rate to the Securities Administrator. If at least two such quotations are provided, the rate for that day will be the arithmetic mean of the quotations. If fewer than two quotations are provided as requested, the rate for that day will be the arithmetic mean of the rates quoted by major banks in New York City, selected by the Securities Administrator, at approximately 11:00 a.m., New York City time, on that day for loans in United States dollars to leading European banks for a one-month period (commencing on the first day of the relevant Interest Accrual Period). If none of such major banks selected by the Securities Administrator quotes such rate to the Securities Administrator, LIBOR for such LIBOR Determination Date will be the rate in effect with respect to the immediately preceding LIBOR Determination Date.

"LIBOR Determination Date" means, with respect to any Interest Accrual Period and any Floating Rate Certificate, the second London Business Day prior to the date on which such Interest Accrual Period commences. Absent manifest error, the Securities Administrator’s determination of LIBOR will be conclusive.

"London Business Day" means a day on which commercial banks in London are open for business (including dealings in foreign exchange and foreign currency deposits).

"Reference Banks" means four major banks in the London interbank market selected by the Securities Administrator.

Distributions of Principal on the Certificates

As of any Distribution Date, principal on certificates will generally be paid from collections or Advances allocated to the related Collateral Group.

Principal collections or Advances on the Mortgage Loans are allocated to the various Collateral Groups on the basis of the Applicable Fractions of the scheduled principal balance of each Mortgage Loan having a Net Rate within a specified range. These Applicable Fractions will be set forth in the prospectus supplement.

The specified portions of principal collections on each Mortgage Loan allocable to a Collateral Group and distributable to the related certificates are calculated for the purpose of "ratio stripping" each Mortgage Loan or, in other words, allocating the Mortgage Loans or portions thereof to Collateral Groups in such a way as to ensure that interest collections on the Mortgage Loans will be sufficient to support the interest rate on the certificates related to the Collateral Groups that share principal of the Mortgage Loans. Since certificateholders’ entitlements to principal will be primarily based on distributions from the related Collateral Groups, the performance of the Mortgage Loans or portion thereof allocated to each of those Collateral Groups will determine the principal distributions of each related class of certificates on each Distribution Date. Prospective investors are encouraged to also consider that the Mortgage Loans contributing to each Collateral Group have different characteristics—in particular, interest rates—that will have particular bearing on the prepayment experience of the related Mortgage Loans or portion thereof allocated to that Collateral Group and, therefore, the related certificates. For example, Mortgage Loans with lower Net Rates might be expected to experience lower rates of prepayment than Mortgage Loans with higher Net Rates. Consequently, the certificates related to Collateral Groups to which lower rate Mortgage Loans are allocated may be expected to pay at a slower rate than certificates related to Collateral Groups to which higher rate Mortgage Loans are allocated. See "Yield and Prepayment Considerations" in this term sheet supplement and in the prospectus.

As described in greater detail below, amounts distributable as principal to the Senior Certificates (other than the Class A-P Certificates) and Subordinate Certificates related to a Collateral Group (other than the Collateral Group or Collateral Groups related to the Class A-P Certificates) as a whole will additionally be allocated between such Senior Certificates and Subordinate Certificates on the basis of the Senior Principal Distribution Amount and the Subordinate Principal Distribution Amount for that Collateral Group, respectively. Such allocation, in particular, will for specified periods result in a disproportionate distribution of prepayments between such Senior Certificates and Subordinate Certificates. See "—Glossary of Definitions Relating to the Priority of Distributions" and "Yield and Prepayment Considerations" in this term sheet supplement.

Glossary of Definitions Relating to the Priority of Distributions

Certain definitions are necessary to understand the priority of interest and principal distributions to the certificates. These terms are defined below:

"Accrued Certificate Interest" means, for any of class of certificates entitled to interest on any Distribution Date, interest accrued for the related Interest Accrual Period on the Class Principal Balance (or Notional Amount) of a class of certificates at the related interest rate plus any unpaid portion of Accrued Certificate Interest from prior Distribution Dates, without interest on such overdue interest, as reduced by such class’s share of the amount of any reduction of interest collectible on any related Mortgage Loan as a result of application of the Servicemembers Civil Relief Act, as amended, and any comparable state or local laws (the "Relief Act" and any such reduction, a "Relief Act Reduction"). The interest portion of any Relief Act Reduction will be allocated among the related Collateral Groups based on the Applicable Fractions for such Mortgage Loan and will be further allocated among the interest bearing Senior Certificates of the related Certificate Group and the related Subordinate Certificates proportionately based on (1) in the case of such Senior Certificates, the Accrued Certificate Interest otherwise distributable thereon and (2) in the case of such Subordinate Certificates, interest accrued on their related Apportioned Principal Balances (as defined herein), without regard to any reduction pursuant to this paragraph, for that Distribution Date.

"Applicable Fraction" means, for each Mortgage Loan and any Collateral Group, the fraction set forth above under "Distributions of Principal on the Certificates."

"Apportioned Principal Balance" means, for any class of Subordinate Certificates for any Distribution Date, the Class Principal Balance of that class immediately prior to that Distribution Date multiplied by a fraction, the numerator of which is the applicable Group Subordinate Amount for that date and the denominator of which is the sum of the Group Subordinate Amounts for all of the related Collateral Groups for that date.

"A-P Principal Distribution Amount" means, (a) for the Collateral Group related to each class of Class A-P Certificates and any Distribution Date:

(1)

the Applicable Fractions for that class of Class A-P Certificates of items (1), (2) and (3) of the definition of Principal Payment Amount;

(2)

the Applicable Fractions for that class of Class A-P Certificates of all Payoffs and Curtailments for each Mortgage Loan contributing to such Collateral Group, that were received during the preceding calendar month or from the second day of the preceding calendar month through the first day of the current calendar month (as specified in the applicable Servicing Agreement); and

(3)

the Applicable Fractions for that class of Class A-P Certificates of the principal portion of the Liquidation Principal for each Liquidated Mortgage Loan contributing to such Collateral Group.

"Class A-X Notional Amount" means, for each Distribution Date, the total principal balance as of the first day of the month immediately preceding the month of such Distribution Date (after giving effect to all payments scheduled to be made on such date whether or not received) of the Premium Loans in each related Loan Group multiplied by the following fraction:

the weighted average of the Net Rates of the Premium Loans in such Loan Group as of the first day of such month minus the Designated Rate for the applicable Collateral Group
the Certificate Interest Rate on such class of Class A-X Certificates.

"Credit Support Depletion Date" means with respect to either group of Subordinate Certificates, the first Distribution Date (if any) on which the aggregate Certificate Balance of such Subordinate Certificates has been or will be reduced to zero.

"Current Realized Losses" means, for each class of Class A-P Certificates and each Distribution Date, the sum of the related Applicable Fraction of Realized Losses realized during the preceding calendar month on each related Discount Loan.

"Designated Rates" means, for each Collateral Group, the "Designated Rates" as set forth in the prospectus supplement.

"Due Period" means, for any Distribution Date, the period beginning on the second day of the month immediately preceding the month in which such Distribution Date occurs and ending on the first day of the month in which such Distribution Date occurs.

"Interest Only Certificate" means any Class A-X Certificate and any other class of certificate designated as an "Interest Only Certificate" in the prospectus supplement.

"Liquidation Principal" means, for any Distribution Date, the principal portion of Liquidation Proceeds received from each Mortgage Loan that became a Liquidated Mortgage Loan during the calendar month immediately preceding the month of such Distribution Date.

"Liquidated Mortgage Loan" means any Mortgage Loan for which the related Servicer has determined that it has received all amounts it expects to recover from or on account of such Mortgage Loan, whether from Insurance Proceeds, Liquidation Proceeds or otherwise.

The "NAS Priority Amount" for any Distribution Date and class of NAS Certificates is equal to the lesser of (i) the sum of (x) the product of the related NAS Percentage for such date, the NAS Scheduled Principal Percentage for such date and a percentage (which may be 100%) of the Scheduled Principal Amount for the related Collateral Group and such date and (y) the product of the related NAS Percentage for such date, the NAS Prepayment Shift Percentage for such date and a percentage (which may be 100%) of the Unscheduled Principal Amount for the related Collateral Group and such date and (ii) the Class Principal Balance of such NAS Certificates immediately prior to such date. Notwithstanding the foregoing, (i) on and after the related Credit Support Depletion Date, such NAS Certificates shall be entitled to their pro rata share of all scheduled and unscheduled payments of principal related to the related Collateral Group and (ii) on the date on which the Class Principal Balance of the related Senior Certificates in the related Certificate Group have been reduced to zero, such NAS Certificates shall be entitled to any remaining Senior Principal Distribution Amount for the related Collateral Group allocable to the other Certificates in related Certificate Group and thereafter, the related NAS Priority Amount will equal a percentage (which may be 100%) of the Senior Principal Distribution Amount for the related Collateral Group. The "NAS Percentage" for any Distribution Date and class of NAS Certificates will be equal to the lesser of (i) 100% and (ii) the percentage obtained by dividing (x) the Class Principal Balance of such class of NAS Certificates immediately prior to such date by (y) the aggregate Class Principal Balance of such NAS Certificates and the other classes of related Certificates in the related Certificate Group immediately prior to such date.

The "NAS Scheduled Principal Percentage" for any Distribution Date during the five years beginning on the first Distribution Date will be 0%. Thereafter, the NAS Scheduled Principal Percentage for any Distribution Date occurring on or after the fifth anniversary of the first Distribution Date will be 100%. The "NAS Prepayment Shift Percentage" for any Distribution Date during the five years beginning on the first Distribution Date will be 0%. Thereafter, the NAS Prepayment Shift Percentage for any Distribution Date occurring on or after the fifth anniversary of the first Distribution Date will be as follows: for any Distribution Date in the first year thereafter, 30%; for any Distribution Date in the second year thereafter, 40%; for any Distribution Date in the third year thereafter, 60%; for any Distribution Date in the fourth year thereafter, 80%; and for any subsequent Distribution Date, 100%.

"Notional Amount" means each Class A-X Notional Amount and the notional amount of any class of Interest Only Certificates set forth in the term sheet.

"PAC Certificates" means any class of certificates designated as a planned amortization class in the term sheet.

"PAC Scheduled Amount" means, for the PAC Certificates and any Distribution Date, the amount set forth in the term sheet for such Distribution Date.

"Payoff" means a prepayment in full on any Mortgage Loan.

"Principal Only Certificate" means any class of Class A-P Certificates or any other class of certificates designated as a "Principal-Only Certificate" in the term sheet.

"Principal Payment Amount" means the sum, for each Collateral Group (other than any Collateral Group related to any class of Class A-P Certificates) and any Distribution Date of the Applicable Fraction for each Mortgage Loan contributing to such Collateral Group of:

(1)

the principal portion of Scheduled Payments on each such Mortgage Loan due on the related Due Date and received or advanced during the related Due Period;

(2)

the principal portion of repurchase proceeds received on any related Mortgage Loan for which an obligation to repurchase arose during or before the related Due Period during the calendar month preceding the month of the Distribution Date;

(3)

any other unscheduled payments of principal that were received on any related Mortgage Loan during the preceding calendar month, other than Payoffs, Curtailments, or Liquidation Principal; and

(4)

Current Realized Losses and Deferred Principal Amounts, to the extent of the amount available from the related Subordinate Principal Distribution Amount.

"Principal Prepayment Amount" means, for any Distribution Date and any Collateral Group, the Applicable Fractions of all Payoffs and Curtailments for each Mortgage Loan contributing to such Collateral Group that were received during the preceding calendar month (other than the Applicable Fractions thereof allocable to any class of Class A-P Certificates).

"Scheduled Payment" means, for any mortgage loan, the monthly payment of principal and interest due on such mortgage loan.

"Scheduled Principal Amount" for each Collateral Group and any Distribution Date is equal to the amount described in clause (1) of the definition of Senior Principal Distribution Amount. The "Unscheduled Principal Amount" for each Collateral Group and any Distribution Date is equal to the sum of the amounts described in clauses (2) and (3) of the definition of Senior Principal Distribution Amount.

"Senior Collateral Group Percentage" for each Collateral Group will be as set forth in the prospectus supplement.

"Senior Liquidation Amount" for any Distribution Date and any Collateral Group (other than any Collateral Group related to any class of Class A-P Certificates), will equal the Applicable Fraction for such Collateral Group of the lesser, for each Mortgage Loan contributing to such Collateral Group that became a Liquidated Mortgage Loan (as defined below) during the calendar month preceding the month of such Distribution Date, of (i) the related Senior Collateral Group Percentage of the scheduled principal balance of such Mortgage Loan and (ii) the applicable Senior Prepayment Percentage of the Liquidation Principal derived from such Mortgage Loan.

The "Senior Prepayment Percentage" for each Collateral Group and each Distribution Date before March 2011 will equal 100%. Thereafter, the Senior Prepayment Percentage for each Collateral Group will be calculated as follows:

for any Distribution Date occurring in March 2011 through February 2012, the related Senior Collateral Group Percentage for that Distribution Date plus 70% of the related Subordinate Percentage for that Distribution Date;

for any Distribution Date occurring in March 2012 through February 2013, the related Senior Collateral Group Percentage for that Distribution Date plus 60% of the related Subordinate Percentage for that Distribution Date;

for any Distribution Date occurring in March 2013 through February 2014, the related Senior Collateral Group Percentage for that Distribution Date plus 40% of the related Subordinate Percentage for that Distribution Date;

for any Distribution Date occurring in March 2014 through February 2015, the related Senior Collateral Group Percentage for that Distribution Date plus 20% of the related Subordinate Percentage for that Distribution Date;

for any Distribution Date occurring in or after March 2015 (other than the final Distribution Date), the Senior Prepayment Percentage will equal the related Senior Collateral Group Percentage for that Distribution Date; and

for the final Distribution Date, the Senior Prepayment Percentage will equal 100%.

There are important exceptions to the calculations of the Senior Prepayment Percentages described in the above paragraph. If, on any Distribution Date, the Senior Collateral Group Percentage for a Collateral Group is greater than the original Senior Collateral Group Percentage for such Collateral Group, then no prepayments on the Mortgage Loans contributing to any Collateral Group related to the same Loan Group (or a related Loan Group) will be paid to the related Subordinate Certificates. In addition, the portion of prepayments on the Mortgage Loans contributing to the related Collateral Group distributed to the Senior Certificates may increase upon the occurrence of certain other events set forth in the Trust Agreement. After the Class Principal Balance of each class of Senior Certificates in a Certificate Group has been reduced to zero, the related Senior Prepayment Percentage will be zero.

The "Senior Principal Distribution Amount" for any Distribution Date and each Collateral Group will equal the sum of:

(1)

the related Senior Collateral Group Percentage of the related Principal Payment Amount for such Distribution Date;

(2)

the related Senior Prepayment Percentage of the related Principal Prepayment Amount for such Distribution Date; and

(3)

the related Senior Liquidation Amount for such Distribution Date.

"Subordinate Liquidation Amount," for any Distribution Date and any Collateral Group (other than any Collateral Group related to any class of Class A-P Certificates) will equal the Applicable Fraction of the related Liquidation Principal in respect of each Mortgage Loan contributing to that Collateral Group that became a Liquidated Mortgage Loan during the calendar month preceding the month of the Distribution Date, minus the related Senior Liquidation Amount for such Distribution Date.

The "Subordinate Percentage" for any Collateral Group (other than any Collateral Group related to any class of Class A-P Certificates) and any Distribution Date will equal the excess of 100% over the related Senior Collateral Group Percentage. The Subordinate Percentage as of the Closing Date will be as set forth in the prospectus supplement.

"Subordinate Prepayment Percentage" for any Distribution Date and any Collateral Group (other than any Collateral Group related to any class of Class A-P Certificates) will equal the excess of 100% over the related Senior Prepayment Percentage. Initially, the Subordinate Prepayment Percentage for each Collateral Group will be 0%.

"Subordinate Principal Distribution Amount" for any Distribution Date and each Collateral Group (other than any Collateral Group related to any class of Class A-P Certificates) will be equal to the sum of:

(1)

the related Subordinate Percentage of the related Principal Payment Amount;

(2)

the related Subordinate Principal Prepayment Amount; and

(3)

the related Subordinate Liquidation Amount;

provided, however, that the Subordinate Principal Distribution Amount for each Collateral Group will be reduced by the amounts required to be distributed to the related class of Class A-P Certificates for reimbursement of Current Realized Losses and Deferred Principal Amounts on such Distribution Date. Any reduction in the Subordinate Principal Distribution Amount for any Collateral Group pursuant to this proviso shall reduce the amount calculated pursuant to clause (1), clause (3) and clause (2) above, in that order, and such amounts will nevertheless reduce the Certificate Balance of the applicable class of Subordinate Certificates.

"Subordinate Principal Prepayment Amount" means, for each Distribution Date and each Collateral Group (other than any Collateral Group related to any class of Class A-P Certificates), the Subordinate Prepayment Percentage of the related Principal Prepayment Amount.

"Subordination Level" means, for any class of Subordinate Certificates and any specified date, the percentage obtained by dividing (i) the sum of the Class Principal Balances of all classes of related Subordinate Certificates that are subordinate to such class by (ii) the sum of Class Principal Balances of all related classes of certificates as of such date, before giving effect to distributions and allocations of Realized Losses to the certificates on such date.

"TAC Certificates" means any class of certificates designated as a planned amortization class in the term sheet.

"TAC Scheduled Amount" means, for the TAC Certificates and any Distribution Date, the amount set forth in the term sheet for such Distribution Date.

Available Distribution Amount

On each Distribution Date, the Available Distribution Amount for each Collateral Group and such Distribution Date will be determined and allocated among the related Collateral Groups as provided in the prospectus supplement and will generally include Scheduled Payments due on the Due Date immediately before such Distribution Date, Curtailments received in the previous calendar month to the extent described below, Payoffs received in the previous calendar month to the extent described below and amounts received from liquidations of Mortgage Loans in the previous calendar month and will be distributed to the certificateholders generally as specified in this term sheet supplement and more specifically in the prospectus supplement.

The "Available Distribution Amount" for any Collateral Group and any Distribution Date, as more fully described in the Trust Agreement, will equal the sum of the Applicable Fractions for each Mortgage Loan contributing to such Collateral Group of the following amounts:

(1)

the total amount of all cash (including P&I Advances), Liquidation Proceeds, Condemnation Proceeds, Insurance Proceeds and payments on, and proceeds from the sale of, any debentures issued in respect of any such Mortgage Loan (i) received from or on behalf of the mortgagors with respect to such Mortgage Loans, (ii) advanced by the applicable Servicers on such Mortgage Loans or, to the extent provided in the Trust Agreement, the Master Servicer or the Trustee, or (iii) received from the applicable Servicers as Compensating Interest with respect to such Mortgage Loans, and not previously distributed, except:

(a)

all Scheduled Payments collected but due on a Due Date after such Distribution Date;

(b)

all Curtailments received after the previous calendar month;

(c)

all Payoffs received after the previous calendar month (together with any interest payment received with those Payoffs to the extent that it represents the payment of interest accrued on those Mortgage Loans for the period after the previous calendar month);

(d)

Liquidation proceeds, Condemnation Proceeds and Insurance Proceeds received on the Mortgage Loans after the previous calendar month;

(e)

all amounts that are then due and payable to the applicable Servicer under the related Servicing Agreement;

(f)

the Servicing Fee (net of any amounts payable as Compensating Interest by the applicable Servicer) for each Mortgage Loan;

(g)

any amounts payable in respect of primary mortgage insurance; and

(h)

all related indemnification amounts and other related amounts reimbursable on such Distribution Date to the Securities Administrator, the Trustee, the Custodians or the Master Servicer; and

(2)

the total amount of any cash received by the Securities Administrator or the applicable Servicer from the repurchase by any Loan Seller of any such Mortgage Loans as a result of defective documentation or breach of representations and warranties; provided that the obligation to repurchase arose before the related Due Date;

provided, that interest with respect to any Mortgage Loan that relates to two Collateral Groups will be included in the Available Distribution Amount for each related Collateral Group as follows: first, to the Collateral Group with the lower Effective Net Rate, interest to the extent accrued on the Applicable Fraction of the principal of such Mortgage Loan at the Effective Net Rate for such Collateral Group; and second, to the other Collateral Group related to such Mortgage Loan.

Administration Fees

As described under the definition of "Available Distribution Amount" in this term sheet supplement, funds collected on the Mortgage Loans that are available for distribution to certificateholders will be net of the servicing fee payable on each Mortgage Loan and compensation payable to the Master Servicer and the Trustee. On each Distribution Date, the Securities Administrator, the Master Servicer, the Servicers and the Trustee will be entitled to their fee prior to the certificateholders receiving any distributions. The servicing fee for any Distribution Date for any Mortgage Loan will be an amount equal to one-twelfth of the servicing fee rate, on the Stated Principal Balance of such Mortgage Loan. The following table identifies the per annum fee rates generally applicable in calculating the servicing fee.

Fee

Per Annum Fee Rate

Servicing Fee

0.25% (IndyMac)

0.25% (GMACM)

0.20% (Countrywide)

0.25% (Conduit Loans)

The servicing fee rates generally represent the rates expected for the Mortgage Loans and the actual servicing fee rates for the Mortgage Loans may exceed these rates, for example, the servicing fee rate for certain mortgage loans serviced by Countrywide may increase in the future to a per annum servicing fee rate of 0.375%.

Priority of Distributions

On each Distribution Date prior to the occurrence of a Credit Support Depletion Date, the Available Distribution Amount for each Collateral Group will be distributed as follows:

(1)

to each class of Senior Certificates (other than the Principal Only Certificates) related to such Collateral Group (other than any Collateral Group related to any class of Class A-P Certificates), Accrued Certificate Interest thereon, pro rata in proportion to the amount of Accrued Certificate Interest owing to each such class;

(2)

to the Senior Certificates (other than the Interest Only Certificates) related to such Collateral Group, to the extent of the remaining Available Distribution Amount for the related Collateral Group, concurrently as follows:

(a)

to the certificates in each Certificate Group, in reduction of their respective Class Principal Balances, in the order of priorities to be set forth in the prospectus supplement, from the Available Distribution Amount for the related Collateral Group in an amount up to the Senior Principal Distribution Amount for that Collateral Group for such Distribution Date, until the Class Principal Balance of each such certificate is reduced to zero;

(b)

to each class of Class A-P Certificates, from the Available Distribution Amount for the related Collateral Group, the related A-P Principal Distribution Amount for such Collateral Group, in reduction of their Class Principal Balance, until the Class Principal Balance thereof is reduced to zero; and

(3)

from amounts otherwise payable to the related Subordinate Certificates, to the related class of Class A-P Certificates, the principal portion of Current Realized Losses and the Deferred Principal Amount for such Class A-P Certificates and such Distribution Date; provided, however, that, if necessary, the aggregate of all such amounts distributed on such Distribution Date shall not exceed the related aggregate Subordinate Principal Distribution Amount (without regard to the proviso of such definition) for the related Subordinate Certificates and, provided further, that such amounts will not reduce the Class Principal Balance of such Class A-P Certificates;

(4)

to the extent of the remaining Available Distribution Amount for each Collateral Group (other than any Collateral Group related to any class of Class A-P Certificates), but subject to the prior distribution of amounts described under "—Cross-Collateralization" below, to the related classes of Subordinate Certificates, in their order of seniority the sum of (i) Accrued Certificate Interest pro rata on the basis of the amount owing to each such class, and (ii) their pro rata shares, based on their outstanding Certificate Balances, of the Subordinate Principal Distribution Amount for each such Collateral Group, as applicable; provided, however, that on any Distribution Date on which the Subordination Level for any class of Subordinate Certificates is less than its Subordination Level as of the Closing Date, the portion of the Subordinate Principal Prepayment Amount otherwise allocable to the class or classes of related Subordinate Certificates junior to such class will be allocated pro rata to the most senior class of related Subordinate Certificates for which the Subordination Level on such Distribution Date is less than the Subordination Level as of the Closing Date and all classes of related Subordinate Certificates senior thereto;

(5)

to each related class of certificates, in the order of their seniority, the amount of any unreimbursed Realized Losses previously allocated to such certificates; and

(6)

to the Residual Certificates, after all of the other classes of certificates have been paid in full, the remainder, if any, which is expected to be zero, of the Available Distribution Amount for all Collateral Groups.

On each Distribution Date on or after the Credit Support Depletion Date, to the extent of the Available Distribution Amount allocable to each Collateral Group on such Distribution Date, distributions will be made to the Senior Certificates related to each such Collateral Group, in respect of interest (pro rata according to Accrued Certificate Interest for such Distribution Date) and then with respect to principal (pro rata according to their outstanding principal balances) and the remainder (other than any Fair Market Value Excess remaining after the optional termination of the Trust Fund), if any, which is expected to be zero, of the Available Distribution Amount for each such Collateral Group will be distributed to the holders of one or more classes of related Residual Certificates.

Distributions with Respect to Exchangeable Classes

In the event that certificates comprising a Combination Group are exchanged for their related Exchangeable Certificates, such Exchangeable Certificates will be entitled to a proportionate share of the principal distributions on each class of certificates in the related Combination Group. In addition, Exchangeable Certificates will bear a proportionate share of losses and interest shortfalls allocable to each class of certificates in the related Combination Group.

Subordination and Allocation of Losses

Each group of Subordinate Certificates will be subordinate in right of payment and provide credit support to the related Senior Certificates to the extent described in this term sheet supplement. The support provided by each group of Subordinate Certificates is intended to enhance the likelihood of regular receipt by the related Senior Certificates of the full amount of the monthly distributions of interest and principal to which they are entitled and to afford the related Senior Certificates protection against certain losses. The protection afforded to the related Senior Certificates by such Subordinate Certificates will be accomplished by the preferential right on each Distribution Date of the related Senior Certificates to receive distributions of interest and principal to which they are entitled before distributions of interest and principal to the related Subordinate Certificates and by the allocation of losses to such Subordinate Certificates prior to any allocation of losses on the Mortgage Loans contributing to any Collateral Group to the related Senior Certificates.

In addition, each class of Subordinate Certificates will be subordinate in right of payment to each class of related Subordinate Certificates with a lower numerical class designation. The protection afforded to a class of Subordinate Certificates by the classes of related Subordinate Certificates with higher numerical class designations will be similarly accomplished by the preferential right of those classes with lower numerical class designations to receive distributions of interest and principal before distributions of interest and principal to those classes of related Subordinate Certificates with higher numerical class designations.

As is more fully set forth below, on each Distribution Date, the Applicable Fractions of the principal portion of each Realized Loss on a Mortgage Loan will be allocated to the classes of the related Certificate Group in reduction of Class Principal Balance thereof.

To the extent that the Applicable Fraction of the principal portion of a Realized Loss has been allocated in reduction of Class Principal Balance of a class of Class A-P Certificates and not reimbursed on the related Distribution Date or prior Distribution Dates, such class shall be entitled (from amounts otherwise distributable to the related Subordinate Certificates in respect of principal) to an amount equal to such unreimbursed loss on future Distribution Dates, until such loss has been fully repaid. Such entitlement is referred to in this term sheet supplement as the "Deferred Principal Amount" and is distributable in the manner described under "—Priority of Distributions" above. The distribution of any Deferred Principal Amount to a class of Class A-P Certificates on any Distribution Date will not result in a further reduction of the Certificate Balance of such certificates, but instead will result in the reduction of Class Principal Balances of the related Subordinate Certificates, in reverse order of seniority, until each of their Class Principal Balances has been reduced to zero, as is more fully set forth herein.

The allocation of the principal portion of any loss as described above will be achieved by reducing the Class Principal Balance of the related class by the amount of such loss on the applicable Distribution Date. The amount paid on any Distribution Date in respect of Current Realized Losses or Deferred Principal Amounts will be applied to reduce Class Principal Balances of the related Subordinate Certificates in inverse order of seniority.

In the event of a personal bankruptcy of a mortgagor, the bankruptcy court may establish a Deficient Valuation. The amount of the secured debt could be reduced to such Deficient Valuation amount, and the holder of such loan thus would become an unsecured creditor to the extent the outstanding principal balance of such loan exceeds the value so assigned to the Mortgaged Property by the bankruptcy court. In addition, certain other modifications of the terms of a loan can result from a bankruptcy proceeding, including the reduction of the amount of the Monthly Payment on the related loan.

A "Realized Loss" on a Liquidated Mortgage Loan, generally equals the excess of (a) the sum of (i) the outstanding principal balance of the Mortgage Loan, (ii) all accrued and unpaid interest thereon, and (iii) the amount of all Servicing Advances and other expenses incurred with respect to such Mortgage Loan (including expenses of enforcement and foreclosure) over (b) Liquidation Proceeds realized from such Mortgage Loan. Realized Losses may also be realized in connection with unexpected expenses incurred by the Trustee, mortgagor bankruptcies and modifications of defaulted Mortgage Loans.

In the event that a Servicer ultimately recovers an amount in respect of a liquidated Mortgage Loan with respect to which a Realized Loss has occurred (any such amount, net of the reasonable fees of the Servicer associated with such recovery, a "Subsequent Recovery" with respect to such liquidated Mortgage Loan), such Subsequent Recovery will be distributed in accordance with the payment priorities with respect to principal described under "Description of the Certificates—Distributions of Principal on the Certificates" in this term sheet supplement and the certificate principal balance of any class of Subordinate Certificates that has been reduced by a Realized Loss will be increased, in direct order of seniority, by the lesser of (i) the amount of such Subsequent Recovery and (ii) the aggregate unreimbursed Realized Loss applicable to such class.

Because each group of Subordinate Certificates represent interests in all the Mortgage Loans in the related Loan Groups, the Certificate Balances of such certificates could be reduced to zero as a result of a disproportionate amount of losses on the loans in any Collateral Group in such Loan Group. Therefore, the allocation to the Subordinate Certificates of Realized Losses (other than with respect to any Subsequent Recoveries) on the Mortgage Loans in any related Collateral Group will increase the likelihood that future losses will be allocated to the Senior Certificates related to the Collateral Group that did not incur the loss.

If the Certificate Balances of all of the related Subordinate Certificates have been reduced to zero, further Realized Losses (other than with respect to any Subsequent Recoveries) on the Mortgage Loans contributing to any related Collateral Group (other than the portion thereof allocable to the related class of Class A-P Certificates) will be allocated pro rata to the related Senior Certificates (other than the related Interest Only Certificates), based on their outstanding Certificate Balances in each case until the Class Principal Balance of each such class has been reduced to zero; provided, however, that Realized Losses otherwise allocable to any class of Super Senior Certificates will instead be allocated to the related class or classes of Credit Support Certificates, until the Class Principal Balance thereof has been reduced to zero.

Cross-Collateralization

On each Distribution Date prior to the related Credit Support Depletion Date, but after the date on which the total Certificate Balance of the Senior Certificates of a Certificate Group (other than any class of Class A-P Certificates) has been reduced to zero, amounts otherwise distributable as principal on each class of related Subordinate Certificates, in reverse order of priority, in respect of such class’s Subordinate Class Percentage of the Subordinate Principal Distribution Amount for the Collateral Group relating to such retired Senior Certificates, will be distributed as principal to the related class or classes of Senior Certificates (other than the Interest Only Certificates) remaining outstanding, until the Class Principal Balances thereof have been reduced to zero, provided that on such Distribution Date (a) the related Total Subordinate Percentage for such Distribution Date is less than 200% of such Total Subordinate Percentage as of the Cut-Off Date or (b) the average outstanding principal balance of the Mortgage Loans in the related Loan Group delinquent 60 days or more (including Mortgage Loans in foreclosure or bankruptcy and real property owned by the Trust Fund) during the most recent six months as a percentage of the related Group Subordinate Amount is greater than or equal to 50%. All distributions described above will be made in accordance with the priorities set forth under "—Priority of Distributions" above.

The "Total Subordinate Percentage" at any time will equal (a) with respect to any group of Subordinate Certificates, the sum of the Class Principal Balances of such Subordinate Certificates divided by the sum of the outstanding principal balances for all the Mortgage Loans in the related Collateral Groups (other than the Applicable Fractions thereof allocable to the related class of Class A-P Certificates).

The "Group Subordinate Amount" with respect to each Collateral Group and any Distribution Date is the excess of the sum of the Applicable Fractions of the outstanding principal balances for all the Mortgage Loans contributing to such Collateral Group (other than the Applicable Fractions thereof allocable to any class of Class A-P Certificates, the related "Non-AP Pool Balance") for the immediately preceding Distribution Date for that Collateral Group over the total Certificate Balance of the Senior Certificates of the related Certificate Group (other than any class of Class A-P Certificates) immediately prior to that Distribution Date.

The "Subordinate Class Percentage" for each class of Subordinate Certificates for each Distribution Date is equal to the percentage obtained by dividing the Class Principal Balance of such class immediately prior to such Distribution Date by the aggregate Certificate Principal Balance of all related Subordinate Certificates immediately prior to such date.

In addition, if on any Distribution Date the total Certificate Balance of the Senior Certificates of a Certificate Group (other than any Class A-P Certificates and after giving effect to distributions to be made on that Distribution Date) is greater than the Non-AP Pool Balance of the related Collateral Group (any such Group, an "Undercollateralized Group"), all amounts with respect to the related Mortgage Loans otherwise distributable as principal on the related Subordinate Certificates, in reverse order of priority (other than amounts needed to pay any Deferred Principal Amounts or unpaid interest shortfalls) (or, following the Credit Support Depletion Date, such amounts described in the following sentence), will be distributed as principal to the Senior Certificates (other than any Class A-P Certificates and any other related Interest Only Certificates) of the Undercollateralized Group, until the total Certificate Balance of such Senior Certificates equals the Non-AP Pool Balance of the related Collateral Group (such distribution, an "Undercollateralization Distribution"). In the event that a Certificate Group constitutes an Undercollateralized Group on any Distribution Date following the Credit Support Depletion Date, Undercollateralization Distributions will be made from the excess of the Available Distribution Amount from each related Collateral Group that does not constitute an Undercollateralized Group remaining after all required amounts have been distributed to the Senior Certificates (other than any Class A-P Certificates and Class A-X Certificates) of such other Certificate Groups. In addition, the amount of any unpaid interest shortfalls with respect to the Undercollateralized Group (including any interest shortfalls for the related Distribution Date) will be distributed to the Senior Certificates (other than any Class A-P Certificates) of the Undercollateralized Group prior to the payment of any Undercollateralization Distributions from amounts otherwise distributable as principal on the related Subordinate Certificates, in reverse order of priority (or, following the related Credit Support Depletion Date, as provided in the preceding sentence). If more than one of the Certificate Groups related to a Loan Group are Undercollateralized Groups, the distributions described above will be made in proportion to the amount by which the aggregate Certificate Balance of the Senior Certificates (other than any Class A-P Certificates) exceeds the Non-AP Pool Balance of the related Collateral Group. All distributions described above will be made in accordance with the priorities set forth under "—Priority of Distributions" above.

Advances

For each Mortgage Loan, the applicable Servicer will make advances of principal and interest ("P&I Advances") to the related Collection Account on or before each Servicer Remittance Date to cover any shortfall between (i) Monthly Payments for that Mortgage Loan and (ii) the amounts actually collected on account of those payments. In addition, the applicable Servicer will advance amounts necessary to preserve the Trust’s interest in the Mortgaged Properties or the Mortgage Loans, such as property taxes or insurance premiums that the applicable mortgagor failed to pay. These advances are referred to as "Servicing Advances" (and, together with P&I Advances, "Advances"). However, if a Servicer determines, in good faith, that an otherwise required Advance would not be recoverable from Insurance Proceeds, Condemnation Proceeds, Liquidation Proceeds or other amounts collected on the particular Mortgage Loan, it will not make an Advance. Advances are reimbursable to the Servicers from cash in the related Collection Account before payments to the certificateholders if a Servicer determines that Advances previously made are not recoverable from Insurance Proceeds, Condemnation Proceeds, Liquidation Proceeds or other amounts recoverable for the applicable Mortgage Loan. The Master Servicer, acting as successor servicer, will advance its own funds to make P&I Advances if a Servicer is required but fails to do so (unless the P&I Advance is deemed by the Master Servicer to be nonrecoverable) as required under the Trust Agreement; and if the Master Servicer has been terminated or has resigned and no successor master servicer has assumed the duties of Master Servicer under the Trust Agreement, then the Trustee (acting as successor master servicer) will make such P&I Advances (unless the P&I Advance is deemed by the Trustee to be nonrecoverable) pursuant to the terms of the Trust Agreement.

Upon liquidation of a Mortgage Loan, the related Servicer or Master Servicer, as applicable, will be entitled to reimbursement of Advances. Each Servicer will be entitled to withdraw (or debit) from the related Collection Account out of the Liquidation Proceeds, Condemnation Proceeds or Insurance Proceeds recovered on any defaulted Mortgage Loan, prior to the calculation of the percentage of the Available Distribution Amount representing its normal servicing compensation on the applicable Mortgage Loan, unreimbursed Advances made on the Mortgage Loan. If a Servicer has expended its own funds to restore a damaged Mortgaged Property and such funds have not been reimbursed under any insurance policy, it will be entitled to withdraw (or debit) from the related Collection Account out of related Liquidation Proceeds, Condemnation Proceeds or Insurance Proceeds an amount equal to such expenses incurred by it, in which event the certificateholders may suffer a loss up to the amount so expended. The rights of each Servicer and the Master Servicer to receive Servicing Fees and Master Servicing Fees, respectively, or other compensation (to the extent actually collected), or for the reimbursement of Advances from collections on the related Mortgage Loans, as described more fully in the Trust Agreement, are senior to the rights of certificateholders to receive payments of interest and principal on the certificates on each Distribution Date.

Optional Purchase of the Mortgage Loans

On any Distribution Date on which the aggregate outstanding principal balance of the Mortgage Loans in a Loan Group or in related Loan Groups is less than 1% of the aggregate scheduled principal balance of such Mortgage Loans as of the Cut-Off Date, the Master Servicer will have the option to purchase from the Trust Fund such Mortgage Loans and all property acquired in respect of such Mortgage Loans remaining in the Trust Fund. Any such optional purchase will cause the retirement of the related classes of certificates.

The purchase price for any such optional purchase will equal the greater of (x) the sum of (a) 100% of the aggregate outstanding principal balance of the applicable Mortgage Loans (other than Liquidated Mortgage Loans), plus accrued interest at the applicable mortgage interest rates and the amount of outstanding Servicing Advances on such Mortgage Loans through the Due Date preceding the date of purchase, less bankruptcy losses that would otherwise have been allocated to the related certificates, and (b) the lesser of (1) the scheduled principal balance of the applicable Mortgage Loans related to all other applicable property in the Trust Fund, plus accrued interest at the applicable mortgage rates and (2) the fair market value of all other applicable property in the Trust Fund, and (y) the aggregate fair market value of all the assets in the Trust Fund related to such Mortgage Loans, as determined in accordance with the Trust Agreement. The proceeds of the sale of such assets of the Trust Fund (other than, with respect to any Mortgage Loan and the related property, an amount equal to the excess, if any, of the amount in clause (y), over the sum of the amount in clause (x), in each case as set forth in the immediately preceding sentence (such excess, the "Fair Market Value Excess")) will be distributed to the holders of the related classes of certificates, in accordance with the order of priorities set forth under "Description of the Certificates–Distributions" in this term sheet supplement and in the prospectus supplement. Any Fair Market Value Excess received in connection with the purchase of either set of such Loan Groups will be distributed to the holders of one or more classes related Residual Certificates.

Except to the extent provided above with respect to allocating any Fair Market Value Excess to the holders of one or more classes of Residual Certificates, the proceeds of such a purchase will be treated as a prepayment of the related Mortgage Loans for purposes of distributions to certificateholders. Accordingly, the exercise of the right to purchase assets of the applicable Mortgage Loans as set forth above will effect early retirement of the related certificates and the applicable certificateholders will receive distributions on the Distribution Date following the month in which such assets are purchased. See "Administration—Termination; Optional Termination" in the prospectus.

Rated Final Distribution Date

Collection Accounts, Master Servicer Account and Certificate Account

Pursuant to the Servicing Agreements, each Servicer is required to establish and maintain one or more accounts designated as collection or custodial accounts (each, a "Collection Account") into which it must deposit, within the time period specified in the applicable Servicing Agreement, payments of principal and interest on the Mortgage Loans, including principal prepayments, Insurance Proceeds, Liquidation Proceeds, Condemnation Proceeds and the proceeds of any purchase of the Mortgage Loans due to breaches of representations or warranties, net of the Servicing Fee, late payment fees, assumption fees and incentive servicing fees, which such Servicer is entitled to retain. Collections that relate to Monthly Payments due on or before the Cut-Off Date, however, regardless of when received, belong to the related Loan Seller and will not be deposited to the related Collection Account. The Collection Accounts are held in trust for the benefit of the Trust Fund. A Servicer may generally withdraw amounts from the Collection Accounts only for purposes of: (i) remitting the monthly remittance to the Master Servicer, which will remit such amount to the Securities Administrator for deposit into the Certificate Account to enable the Securities Administrator to make monthly distributions to certificateholders, (ii) to reimburse such Servicer, the Master Servicer and the Securities Administrator for Advances and any unreimbursed Servicing Fees, from late payments, Liquidation Proceeds, Insurance Proceeds, Condemnation Proceeds and other collections from the related Mortgage Loan, (iii) to pay such Servicer income on funds invested as servicing compensation, (iv) to pay a Loan Seller amounts received on related Mortgage Loans repurchased by it pursuant to the related Sale Agreement, (v) to reimburse such Servicer for certain indemnification expenses, to the extent not caused by such Servicer's failure, as Servicer, to service the Mortgage Loans in strict compliance with the Servicing Agreement, subject to the maximum amount set forth in the Trust Agreement, (vi) to withdraw amounts deposited in the Collection Accounts in error, (vii) to pay the Securities Administrator and the Trustee any amounts payable pursuant to the Trust Agreement, subject to the maximum amount set forth therein, and (viii) to clear and terminate (at final maturity) the account.

On each Servicer Remittance Date, the Servicers are required to remit to the Master Servicer the Available Distribution Amount with respect to the Distribution Date occurring during the month of such Servicer Remittance Date. The Master Servicer is required to deposit such amount into a trust account established by the Master Servicer under the Trust Agreement for the benefit of the certificateholders (the "Master Servicer Account"), and two Business Days prior to the Distribution Date (the "Master Servicer Remittance Date"), the Master Servicer is required to remit the Available Distribution Amount to the Securities Administrator. Upon receipt, the Securities Administrator is required to deposit funds received from the Master Servicer into a trust account established by the Securities Administrator for the benefit of the certificateholders (the "Certificate Account") from which it will make distributions to the certificateholders on each Distribution Date.

The Certificate Account and the Master Servicer Account must be Eligible Accounts. An "Eligible Account" for purposes of establishment of the Certificate Account and the Master Servicer Account is a trust account: (i) maintained by a depository institution, the long-term unsecured debt obligations of which are rated by each Rating Agency in one of its two highest rating categories at the time of any deposit therein, or (ii) maintained with the Securities Administrator or the Master Servicer, or (iii) an account otherwise acceptable to each Rating Agency. If the definition of Eligible Account is not met, the Certificate Account shall be maintained at the Securities Administrator or any of its affiliates.

In the case of information furnished pursuant to subclauses (i) through (iii) above, the amount shall also be expressed as a dollar amount per $1,000 denomination of certificates.

Within a reasonable period of time after the end of each calendar year, the Securities Administrator will, upon request, make available to each person who at anytime during the calendar year was a holder of a certificate, a statement (which will be based solely upon, and to the extent of, information provided to it by the Master Servicer) containing the information set forth in subclauses (i), (ii), (iii) and (iv) above with respect to the period during which such person was a certificateholder. Such obligation will deemed satisfied to the extent that substantially comparable information is provided by the Master Servicer or the Trustee pursuant to any requirements of the Code as from time to time are in force.

The Securities Administrator may make available each month, to any interested party, the monthly statement to Certificateholders via the Securities Administrator 's internet website. The Securities Administrator's website will be located at www.ctslink.com, and assistance in using the website can be obtained by calling the Securities Administrator 's customer service desk at (301) 815-6600. Parties that are unable to use the above distribution option are entitled to have a paper copy mailed to them via first class mail by notifying the Securities Administrator at the following address: Wells Fargo Bank, N.A., P.O. Box 98, Columbia, Maryland 21046 (or for overnight deliveries at 9062 Old Annapolis Road, Columbia, Maryland 21045). The Securities Administrator shall have the right to change the way such statement is distributed in order to make such a distribution more convenient and/or more accessible and the Securities Administrator shall provide timely and adequate notification to the Certificateholders and the parties to the Trust Agreement regarding any such changes. The Securities Administrator will also make available on its website any reports on Forms 10-D, 10-K and 8-K that have been prepared by the Securities Administrator with respect to the Trust Fund through the EDGAR system.

YIELD AND PREPAYMENT CONSIDERATIONS

General

The yield to maturity of each class of certificates will depend upon, among other things, the price at which such certificates are purchased, the applicable interest rate on the certificates, the actual characteristics of the Mortgage Loans in the related Collateral Group, the rate of principal payments (including prepayments) on the Mortgage Loans in the related Collateral Group and the rate of liquidations on the Mortgage Loans in the related Collateral Group. The yield to maturity of the each class of Exchangeable Certificates will depend on the yield to maturity of the related classes of the related Regular Certificates. The yield to maturity to holders of certificates (other than the LIBOR Certificates and the Principal Only Certificates) will be lower than the yield to maturity otherwise produced by the applicable interest rate and purchase price of those certificates because principal and interest distributions will not be payable to the certificateholders until the 25th day of the month following the month of interest accrual (without any additional distribution of interest or earnings for the delay).

Any net interest shortfalls, as described under the heading "Description of the Certificates–Distributions" in this term sheet supplement, will adversely affect the yields on the offered certificates. In addition, although all Realized Losses (other than with respect to any Subsequent Recoveries) initially will be borne by the related Subordinate Certificates, in the reverse order of their numerical class designations (either directly or through distributions of Deferred Principal Amounts on the related class of Class A-P Certificates, as applicable), the Applicable Fractions of Realized Losses (other than with respect to any Subsequent Recoveries) occurring on or after the Credit Support Depletion Date will be allocated pro rata to the outstanding class or classes of Senior Certificates related to the Collateral Group in which such Realized Loss occurred; provided, however, that Realized Losses otherwise allocable to any Super Senior Certificates will instead be allocated to the related class or classes of Credit Support Certificates, until the Class Principal Balance thereof has been reduced to zero. Moreover, since the Subordinate Principal Distribution Amount for each Distribution Date will be reduced by the amount of any distributions on a Distribution Date of Current Realized Losses and Deferred Principal Amounts, the amount distributable as principal on each Distribution Date to each class of Subordinate Certificates will be less than it otherwise would be in the absence of the Current Realized Losses and Deferred Principal Amounts. As a result, the yields on the offered certificates will depend on the rate and timing of Realized Losses.

In addition, as described under the heading "Description of the Certificates—Priority of Distributions" in this term sheet supplement, principal distributions on the certificates will be calculated on the basis of principal collections on specified Collateral Groups of Mortgage Loans or portions thereof. Prospective investors in the certificates are urged to consider that the characteristics—in particular, the interest rates—of the Mortgage Loans themselves, portions of which will be allocated to the various Collateral Groups, will have particular bearing on the prepayment rates of the related Mortgage Loans and, therefore, any class of related certificates. Specifically, Mortgage Loans with lower interest rates may be expected to experience lower rates of prepayment than Mortgage Loans with higher interest rates and this will affect the rate of prepayment of the Collateral Groups to which such Mortgage Loans contribute. Consequently, any class of certificates related to any Collateral Group to which lower-rate Mortgage Loans or portions thereof have been allocated may be expected to experience slower rates of prepayment of the Class Principal Balance thereof and any class of certificates related to a Collateral Group to which higher-rate Mortgage Loans or portions thereof have been allocated may be expected to experience faster rates of prepayment of the Class Principal Balance thereof.

Principal Prepayments and Compensating Interest

When a mortgagor prepays a Mortgage Loan in whole or in part between Due Dates for the Mortgage Loan, the mortgagor pays interest on the amount prepaid only to the date of prepayment instead of for the entire month. Absent compensating interest, such a prepayment will cause a shortfall to occur in the amount of interest due to certificateholders since the certificateholders (other than holders of Principal Only Certificates) are entitled to receive a full month of interest. Also, when a Curtailment is made on a Mortgage Loan together with the Scheduled Payment for a month on or after the related Due Date, the principal balance of the Mortgage Loan is reduced by the amount of the Curtailment as of that Due Date, but the principal is not distributed to certificateholders until the Distribution Date in the next month; therefore, one month of interest shortfall accrues on the amount of such Curtailment.

To reduce the adverse effect on certificateholders from the deficiency in interest payable by the mortgagors as a result of a Payoff or Curtailment between Due Dates, each Servicer will remit to the related Collection Account no later than the day before each Servicer Remittance Date an amount equal to any shortfall in interest collections for the previous month resulting from the timing of prepayments on the Mortgage Loans serviced by it (such amount, "Compensating Interest"). The amount of Compensating Interest to be paid by any Servicer on any Distribution Date will not exceed the lesser of (x) the amount required to cause the Master Servicer to receive a full month's interest on any voluntary prepayments in full (and with respect to certain Servicers, any voluntary prepayments in part) of Mortgage Loans serviced by such Servicer received during the related Due Period and (y) 50% of the Servicing Fee payable to such Servicer on the related Distribution Date. In the event the related Servicer does not make a required remittance of Compensating Interest on any Distribution Date, the Master Servicer is required to pay such amount to the extent that such amount does not exceed the total of the Master Servicing Fee for the applicable Distribution Date, through a reduction in the amount of the Master Servicer’s compensation. Shortfalls on any Mortgage Loan and any Distribution Date attributable to the Servicemembers Civil Relief Act, as amended, will be allocated among the related Collateral Groups based on the Applicable Fractions for such Mortgage Loan and will be further allocated among the interest-bearing Senior Certificates of the related Certificate Group and the related Subordinate Certificates proportionately based on (1) in the case of such Senior Certificates, the Accrued Certificate Interest otherwise distributable thereon and (2) in the case of such Subordinate Certificates, interest accrued on their related Apportioned Principal Balances, without regard to any reduction pursuant to this paragraph, for such Distribution Date.

To the extent that the amount of Compensating Interest is insufficient to cover the deficiency in interest payable as a result of the timing of a prepayment, that remaining deficiency will be allocated to the related Senior Certificates and the related Subordinate Certificates (but, in the case of the Subordinate Certificates, only the portion of those Certificates that derives its interest from the related Collateral Group), pro rata according to the amount of interest to which each related class of certificates would otherwise be entitled in reduction of that amount.

Rate of Payments

The rate of principal payments on the certificates entitled to receive principal generally is directly related to the rate of principal payments on the Mortgage Loans in the related Collateral Group, which may be in the form of scheduled payments, principal prepayments or liquidations. See "Risk Factors" in this term sheet supplement and "Yield and Prepayment Considerations" in the prospectus. It is expected that most of the mortgagors may prepay the Mortgage Loans at any time without penalty. A higher than anticipated rate of prepayments would reduce the aggregate principal balance of the Mortgage Loans more quickly than expected. As a consequence, aggregate interest payments for the Mortgage Loans would be substantially less than expected. Therefore, a higher rate of principal prepayments in a Collateral Group could result in a lower than expected yield to maturity on each related class of certificates purchased at a premium, and in certain circumstances investors may not fully recover their initial investments. Conversely, a lower than expected rate of principal prepayments in a specified Collateral Group would reduce the return to investors on any related classes of certificates purchased at a discount, in that principal payments for the Mortgage Loans would occur later than anticipated. There can be no assurance that certificateholders will be able to reinvest amounts received from the certificates at a rate that is comparable to the applicable interest rate on the certificates. Investors are encouraged to fully consider all of the associated risks of investing in the certificates.

PAC and TAC Certificates

The PAC Certificates and TAC Certificates, if any, will be entitled to receive payments, to the extent of available principal, to reduce their Class Principal Balance on each Distribution Date to the related PAC Scheduled Amount or related TAC Scheduled Amount for such Distribution Date, according to the PAC Schedule or TAC Schedule, as applicable, to be set forth in the prospectus supplement. The PAC Schedules, if any, will be prepared on the basis of the Modeling Assumptions and the assumption that the Mortgage Loans prepay at a constant rate within a range of constant prepayment rates (the "Structuring Range"), expressed as a Percentage of PSA. The TAC Schedules, if any, will be prepared on the basis of the Modeling Assumptions and the assumption that the Mortgage Loans prepay at a constant rate equal to a constant prepayment rate (the "Structuring Target"), expressed as a Percentage of PSA. The Structuring Range for the PAC Certificates and the Structuring Target for the TAC Certificates will be specified in the prospectus supplement. There can be no assurance that the Class Principal Balances of the PAC Certificates or TAC Certificates will conform on any Distribution Date to the PAC Scheduled Amount or TAC Scheduled Amount, as applicable, for such Distribution Date, or that distributions of principal on such classes will begin or end on the dates indicated in such schedule, even if prepayments occur at rates that are within the Structuring Range set forth above.

If the Mortgage Loans contributing to the related Collateral Group prepay at rates that are generally below the Structuring Range, the amount available for principal distributions on any Distribution Date may be insufficient to reduce Class Principal Balances of the PAC Certificates to the PAC Scheduled Amount for such Distribution Date, and the weighted average lives of the PAC Certificates may be extended, perhaps significantly. Conversely, if the Mortgage Loans contributing to the related Collateral Group prepay at rates that are generally above the Structuring Range, the weighted average lives of the PAC Certificates may be shortened, perhaps significantly.

Similarly, if the Mortgage Loans contributing to the related Collateral Group prepay at rates that are generally below the Structuring Target, the amount available for principal distributions on any Distribution Date may be insufficient to reduce Class Principal Balances of the TAC Certificates to the TAC Scheduled Amount for such Distribution Date, and the weighted average lives of the TAC Certificates may be extended, perhaps significantly. Conversely, if the Mortgage Loans contributing to the related Collateral Group prepay at rates that are generally above the Structuring Target, the weighted average lives of the TAC Certificates may be shortened, perhaps significantly.

Support Certificates

The prepayment stability of any PAC Certificates or any TAC Certificates will be supported by the PAC Support Certificates or the TAC Support Certificates.

In general, the weighted average lives of the certificates supporting other classes of certificates as described above will be more sensitive to Mortgage Loan prepayments than those of the classes they are supporting. The supporting classes may receive no principal payments for extended periods of time or may receive principal payments that vary widely from period to period.

To the extent that a low rate of principal payments on the related Mortgage Loans results in the related Principal Distribution Amount on any Distribution Date being equal to or less than the amount required to be distributed as principal on any class of certificates that pays principal in accordance with a schedule, the certificates supporting such class will receive no principal on such Distribution Date. Conversely, to the extent that a high rate of principal payments results in the related Principal Distribution Amount being in excess of the amount needed to maintain scheduled payments on any class of certificates, such excess funds will be applied, to the extent of the related Senior Principal Distribution Amount, to the supporting classes in accordance with their schedules, if applicable, or until their Certificate Balances have been reduced to zero. Thus, a rapid rate of prepayments in respect of the related Mortgage Loans may significantly shorten the weighted average lives of certain classes of support Certificates, and a relatively slow rate of prepayments on such Mortgage Loans may significantly extend the weighted average lives of certain classes of support Certificates.

Lack of Historical Prepayment Data

There are no historical prepayment data available for the Mortgage Loans underlying the certificates, and comparable data are not available because the Mortgage Loans underlying the certificates are not a representative sample of mortgage loans generally. In addition, historical data available for mortgage loans underlying mortgage pass-through certificates issued by GNMA, Fannie Mae and Freddie Mac may not be comparable to prepayments expected to be experienced by the mortgage pool because the Mortgage Loans underlying the certificates may have characteristics that differ from the mortgage loans underlying certificates issued by GNMA, Fannie Mae and Freddie Mac.

GSMSC makes no representation that the Mortgage Loans will prepay in the manner or at any of the rates assumed in the tables in the prospectus supplement or below in "—Yield Considerations with Respect to the Interest Only and Principal Only Certificates" and—Yield Considerations with Respect to the Senior Subordinate Certificates." Each investor must make its own decision as to the appropriate prepayment assumptions to be used in deciding whether or not to purchase any of the offered certificates. Since the rate of principal payments (including prepayments) on, and repurchases of, the Mortgage Loans will significantly affect the yields to maturity on the offered certificates (and especially the yields to maturity on the Interest Only and Principal Only Certificates and the Subordinate Certificates), prospective investors are urged to consult their investment advisors as to both the anticipated rate of future principal payments (including prepayments) on the Mortgage Loans and the suitability of the offered certificates to their investment objectives.

Yield Considerations with Respect to the Interest Only and Principal Only Certificates

The yield to maturity on each class of Class A-X Certificates related to any Loan Group will be extremely sensitive to the level of principal prepayments on the Premium Loans in such Loan Group. The interest payable to each class of Class A-X Certificates is based on (i) the excess of the weighted average of the Net Rates for each of the Premium Loans in the related Loan Group or Loan Groups over (ii) the Designated Rate on the applicable Collateral Group in each such Loan Group. Therefore, the yield to maturity on each class of Class A-X Certificates will be adversely affected as a result of faster–than–expected principal prepayments on the Premium Loans in each such Loan Group. Prospective investors are encouraged to fully consider the risks associated with an investment in the Class A-X Certificates, including the possibility that if the rate of principal prepayments on the related Premium Loans is rapid or an optional purchase of the related Mortgage Loans occurs, such investors may not fully recoup their initial investments and may experience a negative yield on their investments.

The foregoing yield considerations will generally also apply to other Interest Only Certificates. In addition, the yield on any certificates that vary inversely with LIBOR will be very sensitive to any increases in LIBOR. As a result, any increases in LIBOR will reduce the yield on such certificates.

The yield to maturity on each class of Class A-P Certificates will be extremely sensitive to the level of principal prepayments on the related Discount Loans. Therefore, the yield to maturity on the Class A-P Certificates will be adversely affected by slower–than–expected prepayments of such Discount Loans and could be reduced to zero.

Because the interest payable on each class of Class A-X Certificates related to any Loan Group is based upon only the Premium Loans in such Loan Group, and the principal distributable to the class of Class A-P Certificates related to such Loan Group is derived only from the Discount Loans in such Loan Group, it is possible that faster–than–expected principal prepayments on such Premium Loans may occur at the same time as slower–than–expected principal prepayments on such Discount Loans, which would result in a lower yield to maturity for such class of Class A-X Certificates and such class of Class A-P Certificates.

Yield Considerations with Respect to the Senior Subordinate Certificates

If the aggregate Certificate Balance of the related Junior Subordinate Certificates is reduced to zero, the yield to maturity on the related Senior Subordinate Certificates will become extremely sensitive to losses on the Mortgage Loans contributing to the related Collateral Groups and the timing of those losses, because the entire amount of those losses will generally be allocated first to the related Junior Subordinate Certificates in reverse order of seniority.

Additional Information

Yield tables and other computational materials will be provided in the prospectus supplement. GSMSC intends to file with the Securities and Exchange Commission additional yield tables and other computational materials for one or more classes of the offered certificates on a Current Report on Form 8-K. Those tables and materials were prepared by the Underwriter at the request of certain prospective investors, based on assumptions provided by, and satisfying the special requirements of, those prospective investors. Those tables and materials are preliminary in nature, and the information contained in the Current Report is subject to, and superseded by, the information in the prospectus supplement.

The Senior Certificates receive distributions of interest and principal to which they are entitled before distributions of interest or principal to the related Subordinate Certificates. In addition, no class of Subordinate Certificates will receive distributions of interest and principal on any Distribution Date until the related Subordinate Certificates senior to that class have received all distributions of interest and principal due on or before that Distribution Date. See the prospectus supplement and "Description of the Certificates—Priority of Distributions" in this term sheet supplement.

Losses on Mortgage Loans will be borne by the related Subordinate Certificates then outstanding in reverse numerical order. If all related Subordinate Certificates have been paid in full then thereafter losses on the related Mortgage Loans will be allocated to the Collateral Groups to which the related Mortgage Loan contributed and, within a Collateral Group, will be allocated pro rata among the Senior Certificates; provided, however, that Realized Losses otherwise allocable to any Super Senior Certificates will instead be allocated to the related class or classes of Credit Support Certificates, until the Class Principal Balance thereof has been reduced to zero. See "Description of the Certificates—Subordination and Allocation of Losses" in this term sheet supplement.

Shifting Interests

The Senior Certificates (other than any Class A-P Certificates and the Interest Only Certificates) will, in the aggregate, generally receive their pro rata shares of all scheduled principal payments for the related Collateral Groups and 100% of all principal prepayments for the related Collateral Groups until the 5th anniversary of the first Distribution Date. Thereafter, the Senior Certificates (other than any Class A-P Certificates and the Interest Only Certificates) will, in the aggregate, generally receive their pro rata share of scheduled principal payments and a disproportionately large, but decreasing, share of principal prepayments (subject to certain triggers that would reduce payments to the related Subordinate Certificates). This will result in a faster rate of return of principal to such Senior Certificates (other than the related Class A-P Certificates and the Interest Only Certificates) than would occur if such Senior Certificates and the related Subordinate Certificates received all payments, including prepayments, pro rata with such Subordinate Certificates, and increases the likelihood that holders of Senior Certificates (other than any Class A-P Certificates and the Interest Only Certificates) will be paid the full amount of principal to which they are entitled. Any NAS Certificates will not necessarily benefit from this accelerated repayment.

If the subordination level for any class of Subordinate Certificates on any Distribution Date is less than the subordination level on the Closing Date for such class of Subordinate Certificates (the "Initial Subordination Levels") the most senior class of related Subordinate Certificates that has not maintained its Initial Subordination Level and all classes of related Subordinate Certificates senior thereto will receive pro rata distributions from principal prepayments otherwise payable to junior classes of related Subordinate Certificates. For a more detailed description of how principal prepayments are allocated among the Senior Certificates and the Subordinate Certificates, see "Description of the Certificates—Priority of Distributions" and the related definitions under "Description of the Certificates—Glossary of Definitions Relating to the Priority of Distributions" in this term sheet supplement.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

The Trust Agreement provides that a designated portion of the Trust Fund will comprise one or more REMICs. The Trustee will cause a REMIC election to be made with respect to each REMIC formed pursuant to the Trust Agreement. Each such REMIC will designate a single class of interests as the residual interest in that REMIC, and the Residual Certificates will represent ownership of the residual interests. Upon the issuance of the offered certificates, McKee Nelson LLP will deliver its opinion to the effect that, assuming compliance with the Trust Agreement, each of the REMICs formed pursuant to the Trust Agreement will qualify as a REMIC within the meaning of Section 860D of the Internal Revenue Code of 1986, as amended (the "Code").

The Securities Administrator, on behalf of the Trustee, will be the Tax Administrator with respect to each of the REMICs, as described in the prospectus. See "Federal Income Tax Consequences" in the prospectus for further information regarding the federal income tax treatment of REMICs and the federal income tax consequences of investing in the offered certificates.

Tax Treatment of REMIC Regular Interests

The offered certificates (other than the Exchangeable Certificates and any class of certificates entitled to receive Basis Risk Shortfalls) will be REMIC regular interests. Any class of certificates entitled to receive Basis Risk Shortfalls (the "Cap Contract Certificates") will be treated as representing (i) an undivided interest in a REMIC regular interest corresponding to that Cap Contract Certificates and (ii) an interest in a limited recourse interest rate cap contract (the "Cap Contract"). See the discussion under "—Additional Considerations for the Cap Contract Certificates" below. For purposes of this summary, the REMIC regular interest corresponding to the Cap Contract Certificates along with the remaining offered certificates (other than the Exchangeable Certificates) are referred to as the "Regular Certificates." See "Federal Income Tax Consequences—Tax Treatment of REMIC Regular Interests and Other Debt Instruments" in the prospectus.

All interest and original issue discount ("OID") on the Regular Certificates will be includible in certificateholders' income using the accrual method of accounting, regardless of the certificateholders' usual methods of accounting. In preparing federal income tax reports to certificateholders and the Internal Revenue Service, the Trustee will treat any Interest Only Certificates, Accrual Certificates and Principal Only Certificates as having been issued with OID, and may treat other classes of Regular Certificates as having been issued with OID. The Interest Only Certificates will be Interest Weighted Certificates (as defined in the prospectus).

The prospectus supplement will specify the prepayment assumptions that will be used in determining the rate of accrual of OID, market discount and premium, if any, for federal income tax purposes. No representation is made that the related Mortgage Loans will prepay at such rates or any other rate.

If actual prepayments differ sufficiently from the prepayment assumption, the calculation of OID for certain classes of offered certificates might produce a negative number for certain accrual periods. If that happens, certificateholders generally will not be entitled to a deduction for that amount, but generally will be required to carry that amount forward as an offset to OID, if any, accruing in future accrual period. See "Federal Income Tax Consequences—OID" in the prospectus.

Additional Considerations for the Cap Contract Certificates

The REMIC regular interest corresponding to a Cap Contract Certificate will be entitled to receive interest and principal payments at the times and in the amounts equal to those made on that Certificate, except that the interest payments will be determined without regard to payments of any Basis Risk Shortfalls. Any amount paid on a Cap Contract Certificate in excess of the amounts payable on the corresponding REMIC regular interest will be deemed to have been paid pursuant to the Cap Contract. Consequently, each beneficial owner of a Cap Contract Certificate will be required to report income accruing with respect to the REMIC regular interest component as discussed under "Tax Treatment of REMIC Regular Interests" above. In addition, each beneficial owner of a Cap Contract Certificate will be required to report net income with respect to the Cap Contract component and will be permitted to recognize a net deduction with respect to the Cap Contract component, subject to the discussion under "—The Cap Contract Component" below. Prospective investors are encouraged to consult their own tax advisors regarding the consequences to them in light of their own particular circumstances of taxing separately the two components comprising the Cap Contract Certificates.

This discussion assumes that the rights of the holders of the Cap Contract Certificates to receive payments in excess of the amounts payable on the corresponding REMIC regular interest will be treated as rights under a notional principal contract rather than as a partnership for federal income tax purposes. Treatment of such rights as a partnership interest could result in differing timing and character consequences to certificateholders and withholding tax consequences for certificateholders who are not U.S. Persons. Prospective investors are encouraged to consult their tax advisors regarding the appropriate tax treatment of the right to receive payments on a Cap Contract Certificate in excess of the amounts payable on the corresponding REMIC regular interest.

Allocations

A beneficial owner of a Cap Contract Certificate must allocate its purchase price for the certificate between its components—the REMIC regular interest component and the Cap Contract component. For information reporting purposes the Trustee will assume the Cap Contract component has nominal value. The Cap Contract is difficult to value, and the Internal Revenue Service could assert that the value of a Cap Contract component as of the Closing Date is greater than the value used for information reporting purposes. Prospective investors are encouraged to consider the tax consequences to them if the Internal Revenue Service were to assert a different value for the Cap Contract component.

Upon the sale, exchange, or other disposition of a Cap Contract Certificate, the beneficial owner of the certificate must allocate the amount realized between the components of the certificate based on the relative fair market values of those components at the time of sale and must treat the sale, exchange or other disposition as a sale, exchange or disposition of the REMIC regular interest component and the Cap Contract component. Assuming that the Cap Contract Certificate is held as a "capital asset" within the meaning of Section 1221 of the Code, gain or loss on the disposition of an interest in the Cap Contract component should be capital gain or loss. For a discussion of the material federal income tax consequences to a beneficial owner upon the disposition of a REMIC regular interest, see "Federal Income Tax Consequences" in the prospectus.

The Cap Contract Component

The portion of the overall purchase price of a Cap Contract Certificate attributable to the Cap Contract component must be amortized over the life of such certificate, taking into account the declining balance of the related REMIC regular interest component. Treasury regulations concerning notional principal contracts provide alternative methods for amortizing the purchase price of an interest rate cap contract. Under one method—the level yield constant interest method—the price paid for an interest rate cap is amortized over the life of the cap as though it were the principal amount of a loan bearing interest at a reasonable rate. Prospective investors are urged to consult their tax advisors concerning the methods that can be employed to amortize the portion of the purchase price paid for the Cap Contract component of a Cap Contract Certificate.

Any payments to a beneficial owner of a Cap Contract Certificate of Basis Risk Shortfalls will be treated as periodic payments on an interest rate cap contract. To the extent the sum of such periodic payments for any year exceeds that year’s amortized cost of the Cap Contract component, 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 shall represent a net deduction for that year. Although not clear, net income or a net deduction should be treated as ordinary income or as an ordinary deduction.

A beneficial owner’s ability to recognize a net deduction with respect to the Cap Contract component is limited under Sections 67 and 68 of the Code in the case of (i) estates and trusts and (ii) individuals owning an interest in such component directly or through a "pass-through entity" (other than in connection with such individual’s trade or business). Pass-through entities include partnerships, S corporations, grantor trusts and non-publicly offered regulated investment companies, but do not include estates, nongrantor trusts, cooperatives, real estate investment trusts and publicly offered regulated investment companies. Further, such a beneficial owner will not be able to recognize a net deduction with respect to the Cap Contract component in computing the beneficial owner’s alternative minimum tax liability.

Status of the Cap Contract Certificates

The REMIC regular interest component of Cap Contract Certificates will be treated as assets described in Section 7701(a)(19) of the Code, and as "real estate assets" under Section 856(c)(4)(A) 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 a Cap Contract Certificate will be interest on obligations secured by interests in real property for purposes of Section 856(c)(3)(B) of the Code, subject to the same limitation in the preceding sentence. The Cap Contract component of the Cap Contract Certificates will not qualify, however, as an asset described in Section 7701(a)(19)(C) of the Code or as a real estate asset under Section 856(c)(4)(A) of the Code. Further, any income attributable to the Cap Contract component will not constitute "interest on obligations secured by mortgages on real property" within the meaning of Section 856(c)(3)(B) of the Code.

Additional Considerations for the Exchangeable Certificates

The arrangement under which the Exchangeable Certificates are created (the "Exchangeable Pool'') will be classified as a grantor trust under subpart E, part I of subchapter J of the Code. The interests in the classes or classes of Regular Certificates that have been exchanged for the classes of Exchangeable Certificates, including any exchanges effective on the Closing Date, will be the assets of the Exchangeable Pool, and each class of Exchangeable Certificates will represent beneficial ownership of a proportionate interest in each Regular Certificate corresponding to that class of Exchangeable Certificates. For a discussion of certain federal income tax consequences applicable to the Exchangeable Certificates, see "Federal Income Tax Consequences—Tax Treatment of Exchangeable Securities" in the prospectus.

ERISA CONSIDERATIONS

The Employee Retirement Income Security Act of 1974, as amended ("ERISA") and Section 4975 of the Internal Revenue Code contain provisions that may affect a fiduciary of an Employee benefit plans or other retirement arrangements subject to Section 406 of ERISA and/or Section 4975 of the Code ("Plans"). Plans, insurance companies or other persons investing Plan assets (see "ERISA Considerations" in the prospectus) are encouraged to carefully review with their legal counsel whether owning offered certificates is permitted under ERISA or Section 4975 of the Internal Revenue Code. The underwriter exemption, as described under "ERISA Considerations—Underwriter Exemption" in the prospectus, may provide an exemption from restrictions imposed by ERISA or Section 4975 of the Internal Revenue Code and may permit a Plan to own, or Plan assets to be used to purchase, the offered certificates other than the Residual Certificates. In addition, under regulations promulgated by the Department of Labor (the "DOL") defining the term "plan assets" published in the Federal Register (the "Plan Asset Regulations"), generally, when a Plan makes an equity investment in another entity (for example, the purchase of a pass-through certificate), the underlying assets of that entity may be considered plan assets unless certain exceptions apply. There can be no assurance that any of the exceptions set forth in the Plan Asset Regulations will apply to the purchase or holding of the offered certificates. Prohibited transactions within the meaning of ERISA and the Code could also arise if the offered certificates are acquired by a Plan with respect to which any of such parties is a Party in Interest.

With respect to the acquisition of the offered certificates by a Plan, the underwriter exemption exempts from certain of the prohibited transaction rules of ERISA the initial acquisition, holding and the subsequent disposition by Plans of certificates such as the offered certificates issued by pass-through trusts holding certain obligations and the operation of the trust issuing the offered certificates, provided the conditions and requirements of the underwriters exemption are met,, including the requirement that an affected Plan must be an "accredited investor" as defined in Rule 501(a)(1) of Regulation D of the Securities and Exchange Commission under the Securities Act of 1933, as amended.

The Department of Labor amended the underwriter's exemption to permit Plans to purchase and hold subordinate certificates such as the Senior Subordinate Certificates if they are rated "BBB-" or better at the time of purchase. See "ERISA Considerations—Underwriter Exemption" in the prospectus. A Plan, or other purchaser acting on its behalf or with Plan assets, that purchases the Senior Subordinate Certificates will be deemed to have represented that:

(1)

the rating condition was satisfied at the time of purchase; or

(2)

the following condition is satisfied:

(a)

it is an insurance company;

(b)

the source of funds used to acquire or hold the certificates is an "insurance company general account" as that term is defined in PTCE 95-60; and

(c)

the conditions in Sections I and III of PTCE 95-60 have been satisfied.

The Trust Agreement will require that if neither condition is satisfied the Plan, or other purchaser acting on its behalf or with Plan assets, will:

(1)

indemnify and hold harmless GSMSC, the Trustee, the Securities Administrator, the Master Servicer, each Servicer, the Custodians and the Underwriter from and against all liabilities, claims, costs or expenses incurred by them as a result of the purchase; and

(2)

be disregarded as purchaser and the immediately preceding permitted beneficial owner will be treated as the beneficial owner of that certificate.

Any fiduciary or other investor of Plan assets that proposes to own the offered certificates on behalf of or with Plan assets of any Plan are encouraged to consult with legal counsel about: (i) whether the specific and general conditions and the other requirements in the underwriter's exemption would be satisfied, or whether any other prohibited transaction exemption would apply, and (ii) the application of the general fiduciary responsibility provisions of ERISA and the prohibited transaction provisions of ERISA and Section 4975 of the Internal Revenue Code to the proposed investment. See "ERISA Considerations" in the prospectus.

GSMSC makes no representation that the sale of any of the offered certificates to a Plan or other purchaser acting on its behalf meets any relevant legal requirement for investments by Plans generally or any particular Plan, or that the investment is appropriate for Plans generally or any particular Plan.

CERTAIN LEGAL INVESTMENT ASPECTS

For purposes of the Secondary Mortgage Market Enhancement Act of 1984, or "SMMEA," the Senior Certificates and, unless otherwise set forth in the term sheet, the Class 1M-1, Class 1B-1, Class 2M-1 and Class 2B-1 Certificates will constitute "mortgage related securities" when they are issued. These mortgage related securities, or "SMMEA Certificates," will be legal investments for persons, trusts, corporations, partnerships, associations, business trusts and business entities (including depository institutions, life insurance companies, and pension funds) created pursuant to or existing under the laws of the United States, or of any state, whose authorized investments are subject to state regulation to the same extent that, under applicable law, obligations issued by or guaranteed as to principal and interest by the United States or any agency or instrumentality of the United States constitute legal investments for such entities. Under SMMEA, if a state enacted legislation before October 4, 1991 specifically limiting the legal investment authority of any type of those entities in "mortgage related securities," the SMMEA Certificates will constitute legal investments for those types of entities only to the extent provided by such legislation. Certain states have enacted such legislation. Investors are encouraged to consult their own legal advisors in determining whether and to what extent the offered certificates constitute legal investments for them.

SMMEA also amended the legal investment authority of federally chartered depository institutions as follows: federal savings and loan associations and federal savings banks may invest in, sell or otherwise deal with the SMMEA Certificates without limitation as to the percentage of their assets represented by the SMMEA Certificates, federal credit unions may invest in the SMMEA Certificates and national banks may purchase the SMMEA Certificates for their own accounts without regard to the limitations generally applicable to investment securities prescribed by 12 U.S.C. 24 (Seventh), in each case subject to such regulations as the applicable federal regulatory authority may adopt.

Institutions whose investment activities are subject to review by certain regulatory authorities may be or may become subject to restrictions on investment in the offered certificates, which could be retroactively imposed. The Federal Financial Institutions Examination Council, the Federal Deposit Insurance Corporation, the Office of the Comptroller of the Currency, the Board of Governors of the Federal Reserve System, the Office of Thrift Supervision and the National Credit Union Administration have adopted guidelines, and have proposed policies, regarding the suitability of investments in various types of derivative mortgage-backed securities, including securities such as the offered certificates. In addition, several states have adopted or are considering regulations that would prohibit regulated institutions subject to their jurisdiction from holding mortgage-backed securities such as the offered certificates. When adopted, the regulations could apply to the offered certificates retroactively. Investors are encouraged to consult their own legal advisors in determining whether and to what extent the offered certificates constitute legal investments for them.

There may be other restrictions on the ability of certain investors, including depository institutions, either to purchase the offered certificates or to purchase the offered certificates representing more than a specified percentage of the investor's assets. Investors are encouraged to consult their own legal advisors in determining whether and to what extent the offered certificates constitute legal investments for them.

METHOD OF DISTRIBUTION

GSMSC has agreed to sell to Goldman, Sachs & Co. (the “Underwriter”), and the Underwriter has agreed to purchase, all of the offered certificates. An underwriting agreement between GSMSC and the Underwriter governs the sale of the offered certificates. Under the underwriting agreement, the Underwriter has agreed to take and pay for all of the offered certificates, if any are taken. The Underwriter will distribute the offered certificates from time to time in negotiated transactions or otherwise at varying prices to be determined at the time of sale. The difference between the purchase price for the offered certificates paid to GSMSC and the proceeds from the sale of the offered certificates realized by the Underwriter will constitute underwriting discounts and commissions.

GSMSC has agreed to indemnify the Underwriter against certain civil liabilities, including liabilities under the Securities Act of 1933.

The Underwriter is an affiliate of the Depositor and GSMC.

LEGAL MATTERS

The validity of the offered certificates and certain federal income tax matters will be passed upon for the Depositor by McKee Nelson LLP, Washington, D.C.

CERTIFICATE RATINGS

It is a condition to the issuance of the offered certificates that they receive the respective ratings from one or more of S&P, Moody’s and Fitch set forth in the term sheet. S&P, Fitch and Moody’s will monitor any of their ratings assigned to the offered certificates while the offered certificates remain outstanding. In the event that the ratings initially assigned to any of the offered certificates by S&P, Fitch or Moody’s are subsequently lowered for any reason, no person or entity is obligated to provide any additional support or credit enhancement to such offered certificates.

A security rating is not a recommendation to buy, sell or hold securities and may be subject to revision, withdrawal or qualification at any time by the assigning rating agency. Each security rating should be evaluated independently of any other security rating.

The ratings assigned to this issue do not constitute a recommendation to purchase or sell these securities. Rather, they are an indication of the likelihood of the payment of principal and interest as set forth in the transaction documentation. The ratings do not address the effect on the certificates' yield attributable to prepayments or recoveries on the underlying Mortgage Loans. Further, the ratings on the Interest Only Certificates do not address whether investors will recover their initial investment. The ratings on the offered certificates address the likelihood of the receipt by certificateholders of all distributions with respect to the underlying Mortgage Loans to which they are entitled. The ratings do not represent any assessment of the likelihood that the rate of principal prepayments by mortgagors might differ from those originally anticipated. As a result of differences in the rate of principal prepayments, certificateholders might suffer a lower than anticipated yield to maturity. See "Risk Factors" and "Yield and Prepayment Considerations" in this term sheet supplement.

Interest Only (IO) Certificates are extremely sensitive to prepayments, which the ratings on the securities do not address. If prepayments are faster than anticipated, investors may fail to recover their initial investment.

Principal Only (PO) Certificates are extremely sensitive to prepayments, which the ratings on the securities do not address. If prepayments are slower than anticipated, investors' yield may be adversely affected. The rating on Principal Only Certificates only addresses the return of the principal balances thereof.

GSMSC has not requested a rating on the offered certificates by any rating agency other than one or more of S&P, Moody’s and Fitch. However, there can be no assurance as to whether any other rating agency will rate the offered certificates, or, if it does, what rating would be assigned by any other rating agency. A rating on the offered certificates by another rating agency, if assigned at all, may be lower than the rating assigned to the offered certificates by S&P, Moody’s or Fitch.
