evidencing a percentage interest in the distributions allocable to the Certificates of the above-referenced Class.

Principal in respect of this Certificate is distributable monthly as set forth herein. Accordingly, the Certificate Balance at any time may be less than the Certificate Balance as set forth herein. This Certificate does not evidence an obligation of, or an interest in, and is not guaranteed by the Depositor, the Master Servicer, the Responsible Party or the Trustee referred to below or any of their respective affiliates. Neither this Certificate nor the Mortgage Loans are guaranteed or insured by any governmental agency or instrumentality.

This certifies that CEDE & CO. is the registered owner of the Percentage Interest evidenced by this Certificate (obtained by dividing the denomination of this Certificate by the aggregate of the denominations of all Certificates of the Class to which this Certificate belongs) in certain monthly distributions pursuant to a Pooling and Servicing Agreement, dated as of January 1, 2006 (the “Agreement”), among GS Mortgage Securities Corp., as depositor (the “Depositor”), Long Beach Mortgage Company, as master servicer (the “Master Servicer”), Long Beach Mortgage Company, as responsible party (the “Responsible Party”) and Deutsche Bank National Trust Company, as trustee (the “Trustee”). To the extent not defined herein, the capitalized terms used herein have the meanings assigned in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of the acceptance hereof assents and by which such Holder is bound.

No transfer of a Certificate of this Class shall be made unless the Trustee shall have received (i) a representation letter from the transferee of such Certificate, acceptable to and in form and substance satisfactory to the Trustee, to the effect that such transferee is not an employee benefit plan subject to Section 406 of ERISA, a plan or arrangement subject to Section 4975 of the Code or a plan subject to Similar Law, or a person acting on behalf of any such plan or arrangement nor using the assets of any such plan or arrangement to effect such transfer, (ii) if the transferee is an insurance company, a representation letter that the transferee is using the assets of its general account and that the purchase and holding of this Certificate are covered under Section I and III of Prohibited Transaction Class Exemption 95-60 or (iii) an Opinion of Counsel satisfactory to the Trustee, to the effect that the purchase and holding of this Certificate will not constitute or result in a prohibited transaction within the meaning of ERISA, Section 4975 of the Code or any Similar Law and will not subject the Trustee or the Servicer to any obligation in addition to those expressly undertaken in the Agreement or to any liability, which representation letter or Opinion of Counsel shall not be an expense of the Trustee, the Servicer or the Trust Fund. In the event that such representation is violated, or any attempt is made to transfer to a plan or arrangement subject to Section 406 of ERISA, Section 4975 of the Code or Similar Law, or a person acting on behalf of any such plan or arrangement or using the assets of any such plan or arrangement, such attempted transfer or acquisition shall be void and of no effect. If this Certificate is a Book-Entry Certificate, the proposed transferee will be deemed to have made the certifications set forth in the representation letter referred to above, as if such Certificate were evidenced by a Physical Certificate.

No transfer of a Certificate of this Class shall be made unless such disposition is exempt from the registration requirements of the Securities Act of 1933, as amended (the “1933 Act”), and any applicable state securities laws or is made in accordance with the 1933 Act and such laws.

In the event that a transfer of a Private Certificate which is a Book-Entry Certificate is to be made in reliance upon an exemption from the Securities Act and such laws, in order to assure compliance with the Securities Act and such laws, the Certificateholder desiring to effect such transfer will be deemed to have made as of the transfer date each of the certifications set forth in the Transferor Certificate in respect of such Certificate and the transferee will be deemed to have made as of the transfer date each of the certifications set forth in the Rule 144A Letter in respect of such Certificate, in each case as if such Certificate were evidenced by a Physical Certificate.

Reference is hereby made to the further provisions of this Certificate set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

This Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose unless manually authenticated by an authorized signatory of the Trustee.

This Certificate is one of a duly authorized issue of Certificates designated as GSAMP Trust 2006-S1 Mortgage Pass-Through Certificates, of the Series specified on the face hereof (herein collectively called the “Certificates”), and representing a beneficial ownership interest in the Trust Fund created by the Agreement.

The Certificateholder, by its acceptance of this Certificate, agrees that it will look solely to the funds on deposit in the Distribution Account for payment hereunder and that the Trustee is not liable to the Certificateholders for any amount payable under this Certificate or the Agreement or, except as expressly provided in the Agreement, subject to any liability under the Agreement.

This Certificate does not purport to summarize the Agreement and reference is made to the Agreement for the interests, rights and limitations of rights, benefits, obligations and duties evidenced thereby, and the rights, duties and immunities of the Trustee.

Pursuant to the terms of the Agreement, a distribution will be made on the 25th day of each month or, if such day is not a Business Day, the Business Day immediately following (the “Distribution Date”), commencing on the first Distribution Date specified on the face hereof, to the Person in whose name this Certificate is registered at the close of business on the applicable Record Date in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to Holders of Certificates of the Class to which this Certificate belongs on such Distribution Date pursuant to the Agreement. The Record Date for each Distribution Date is the last Business Day of the applicable Interest Accrual Period for the related Distribution Date; provided, however, that for any Definitive Certificates, the Record Date shall be the last Business Day of the month immediately preceding the month of such Distribution Date (or if such day is not a Business Day, on the immediately preceding Business Day).

Distributions on this Certificate shall be made by wire transfer of immediately available funds to the account of the Holder hereof at a bank or other entity having appropriate facilities therefor, if such Certificateholder shall have so notified the Trustee in writing at least five Business Days prior to the related Record Date and such Certificateholder shall satisfy the conditions to receive such form of payment set forth in the Agreement, or, if not, by check mailed by first class mail to the address of such Certificateholder appearing in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the offices designated by the Trustee for such purposes, or such other location specified in the notice to Certificateholders of such final distribution.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Trustee and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer and the Trustee with the consent of the Holders of Certificates affected by such amendment evidencing the requisite Percentage Interest, as provided in the Agreement. Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange therefor or in lieu hereof whether or not notation of such consent is made upon this Certificate. The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register of the Trustee upon surrender of this Certificate for registration of transfer at the offices designated by the Trustee for such purposes, accompanied by a written instrument of transfer in form satisfactory to the Trustee and the Certificate Registrar duly executed by the holder hereof or such holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest in the Trust Fund will be issued to the designated transferee or transferees.

The Certificates are issuable only as registered Certificates without coupons in denominations specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of the same Class in authorized denominations and evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

No service charge will be made for any such registration of transfer or exchange, but the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Depositor and the Trustee and any agent of the Depositor or the Trustee may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and neither the Depositor, the Trustee, nor any such agent shall be affected by any notice to the contrary.

On any Distribution Date on which the aggregate Stated Principal Balance of the Mortgage Loans is less than or equal to 10% of the Cut-off Date Pool Principal Balance, the Master Servicer (at the direction of the Majority Class X Certificateholder) will have the option to repurchase, in whole, from the Trust Fund all remaining Mortgage Loans and all property acquired in respect of the Mortgage Loans at a purchase price determined as provided in the Agreement. The obligations and responsibilities created by the Agreement will terminate as provided in Section 9.01 of the Agreement.
