The Company will acquire the Mortgage Loans from GSMC, pursuant to a Xxxx of Sale, to be dated as of June 9, 2006 between the Company and GSMC (the “Xxxx of Sale”).

At or prior to the time when sales to investors of the Publicly Offered Certificates were first made (the “Time of Sale”), the Company had prepared the following information (collectively, the “Time of Sale Information”): the GSAMP 2006-S4 Free Writing Prospectus dated June 1, 2006 (the “Preliminary Free Writing Prospectus”), the GSAMP 2006-S4 Term Sheet dated June 1, 2006 (the “Term Sheet”) and any other “free-writing prospectus” (as defined pursuant to Rule 405 under the Act (as defined herein)) (a “Free Writing Prospectus”) listed on Schedule IV hereto.

(b) The Company will indemnify and hold harmless the Underwriter against any losses, claims, damages or liabilities, joint or several, to which the Underwriter may become subject, under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (1) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or Prospectus as amended or supplemented or any other offering material relating to the Publicly Offered Certificates, or any amendment or supplement thereto, or in any static pool information, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Underwriter for any legal or other expenses reasonably incurred by the Underwriter in connection with investigating or defending any such action or claim, or (2) any untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Information or any Issuer Information (as defined in Section 11(b)) contained in any Free Writing Prospectus prepared by or on behalf of the Underwriter (an “Underwriter Free Writing Prospectus”) or contained in any Free Writing Prospectus which is required to be filed pursuant to Section 11(e)(iii) or Section 11(h), or the omission or alleged omission to state a material fact required to make the statements therein (when read in conjunction with the other Time of Sale Information), in light of the circumstances under which they were made, not misleading, which was not corrected by Corrective Information subsequently supplied by the Company to the Underwriter at any time prior to the Time of Sale, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with (i) information with respect to which each Underwriter has agreed to indemnify the Company pursuant to Section 8(b); provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any such document in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use in the Registration Statement, any Time of Sale Information, any Issuer Free Writing Prospectus or Prospectus.

(b) The Underwriter will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Issuer Free Writing Prospectus, any Time of Sale Information or Prospectus as amended or supplemented or any other offering material relating to the Publicly Offered Certificates or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made (i) in any such document in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred, or (ii) in any Underwriter Free Writing Prospectus (in the case of an omission or an alleged omission, when read in conjunction with the Time of Sale Information); provided, that the Underwriter shall not be obligated to so indemnify and hold harmless (A) with respect to information that is also contained in the Time of Sale Information or (B) to the extent such losses, claims, damages or liabilities are caused by a misstatement or omission resulting from an error or omission in the Issuer Information to the Underwriter which was not corrected by Corrective Information subsequently supplied by the Company to the Underwriter at any time prior to the Time of Sale.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Publicly Offered Certificates to which such loss, claim, damage or liability (or actions in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriter. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriter on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriter agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Publicly Offered Certificates underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls the Underwriter within the meaning of the Act; and the obligations of the Underwriter with respect to any Publicly Offered Certificates under this Section 8 shall be in addition to any liability which the Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

9. The respective indemnities, agreements, representations, warranties and other statements of the Company and the Underwriter as set forth in this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made in connection with the issuance of Certificates by or on behalf of the Underwriter or any controlling person of the Underwriter, or the Company, or any officer or director or controlling person of the Company and shall survive delivery of and payment for the Publicly Offered Certificates.

10. If for any reason the Certificates are not delivered by or on behalf of the Trustee as provided herein, other than by the Underwriter’s failure to comply with its obligations hereunder, the Company will reimburse the Underwriter for all out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred by the Underwriter in making preparations for the purchase, sale and delivery of the Publicly Offered Certificates, but the Company shall be under no further liability to the Underwriter with respect to such Certificates except as provided in Section 6 and Section 8 hereof.

11. (c) Unless preceded or accompanied by a prospectus satisfying the requirements of Section 10(a) of the Act, the Underwriter shall not convey or deliver any written communication to any person in connection with the initial offering of the Publicly Offered Certificates, unless such written communication (1) is made in reliance on Rule 134 under the Act, (2) constitutes a prospectus satisfying the requirements of Rule 430B under the Act or (3) constitutes a Free Writing Prospectus. Without the Company’s prior written consent, the Underwriter shall not convey or deliver in connection with the initial offering of the Publicly Offered Certificates any “ABS informational and computational material,” as defined in Item 1101(a) of Regulation AB under the Act (“ABS Informational and Computational Material”), in reliance upon Rules 167 and 426 under the Act.

(b) The Underwriter shall deliver to the Company, no later than two business days prior to the date of first use thereof, (a) any Underwriter Free Writing Prospectus that contains any “issuer information”, as defined in Rule 433(h) under the Act (“Issuer Information”), and (b) any Free Writing Prospectus or portion thereof that contains only a description of the final terms of the Publicly Offered Certificates. Notwithstanding the foregoing, any Free Writing Prospectus that contains only ABS Informational and Computational Materials may be delivered by the Underwriter to the Company not later than the later of (a) two business days prior to the due date for filing of the Prospectus pursuant to Rule 424(b) under the Act or (b) the date of first use of such Free Writing Prospectus.

(c) The Underwriter represents and warrants to the Company that the Free Writing Prospectuses to be furnished to the Company by the Underwriter pursuant to Section 11(b) will constitute all Free Writing Prospectuses of the type described therein that were furnished to prospective purchasers of Publicly Offered Certificates by the Underwriter in connection with its offer and sale of the Publicly Offered Certificates.

(d) The Underwriter represents and warrants to the Company that each Free Writing Prospectus required to be provided by it to the Company pursuant to Section 11(b), when read together with all other Time of Sale Information, did not, as of the Time of Sale, and will not as of the Closing Date, include any untrue statement of a material fact or omit any material fact necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading; provided however, that the Underwriter makes no representation to the extent such misstatements or omissions were the result of any inaccurate Issuer Information supplied by the Company to the Underwriter, which information was not corrected by Corrective Information subsequently supplied by the Company to the Underwriter prior to the Time of Sale.

(e) The Company agrees to file with the Commission the following: (i) any Issuer Free Writing Prospectus; (ii) any Free Writing Prospectus or portion thereof delivered by the Underwriter to the Company pursuant to Section 11(b); and (iii) any Free Writing Prospectus for which the Company or any person acting on its behalf provided, authorized or approved information that is prepared and published or disseminated by a person unaffiliated with the Company or any other offering participant that is in the business of publishing, radio or television broadcasting or otherwise disseminating communications.

(f) Any Free Writing Prospectus required to be filed pursuant to Section 11(e) by the Company shall be filed with the Commission not later than the date of first use of the Free Writing Prospectus, except that: (i) any Free Writing Prospectus or portion thereof required to be filed that contains only the description of the final terms of the Publicly Offered Certificates shall be filed by the Company with the Commission within two days of the later of the date such final terms have been established for all classes of Publicly Offered Certificates and the date of first use; (ii) any Free Writing Prospectus or portion thereof required to be filed that contains only ABS Informational and Computational Material shall be filed by the Company with the Commission not later than the later of the due date for filing the final Prospectus relating to the Publicly Offered Certificates pursuant to Rule 424(b) under the Act or two business days after the first use of such Free Writing Prospectus; (iii) any Free Writing Prospectus required to be filed pursuant to Section 11(e)(iii) shall, if no payment has been made or consideration has been given by or on behalf of the Company for the Free Writing Prospectus or its dissemination, be filed by the Company with the Commission not later than four business days after the Company becomes aware of the publication, radio or television broadcast or other dissemination of the Free Writing Prospectus; and (iv) the Company shall not be required to file (A) Issuer Information contained in any Free Writing Prospectus of the Underwriter or any other offering participant other than the Company, if such information is included or incorporated by reference in a prospectus or Free Writing Prospectus previously filed with the Commission that relates to the offering of the Publicly Offered Certificates, or (B) any Free Writing Prospectus or portion thereof that contains a description of the Publicly Offered Certificates or the offering of the Publicly Offered Certificates which does not reflect the final terms thereof.

(g) The Underwriter shall file with the Commission any Free Writing Prospectus that is used or referred to by it and distributed by or on behalf of the Underwriter in a manner reasonably designed to lead to its broad, unrestricted dissemination not later than the date of the first use of such Free Writing Prospectus.

(h) Notwithstanding the provisions of Section 11(g), the Underwriter shall file with the Commission any Free Writing Prospectus for which the Underwriter or any person acting on its behalf provided, authorized or approved information that is prepared and published or disseminated by a person unaffiliated with the Company or any other offering participant that is in the business of publishing, radio or television broadcasting or otherwise disseminating written communications and for which no payment was made or consideration given by or on behalf of the Company or any other offering participant, not later than four business days after the Underwriter becomes aware of the publication, radio or television broadcast or other dissemination of the Free Writing Prospectus.

(i) Notwithstanding the provisions of Sections 11(e) and 11(g), neither the Issuing Entity nor the Underwriter shall be required to file any Free Writing Prospectus that does not contain substantive changes from or additions to a Free Writing Prospectus previously filed with the Commission.

(j) The Company and the Underwriter each agree that any Free Writing Prospectuses prepared by it shall contain the following legend:

The depositor has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents the depositor has filed with the SEC for more complete information about the depositor, the issuing trust and this offering. You may get these documents for free by visiting XXXXX on the SEC Web site at xxx.xxx.xxx. Alternatively, the depositor, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you request it by calling toll-free 0-000-000-0000.

(k) In the event that the Underwriter becomes aware that, as of the Time of Sale, any Issuer Information contained in any Underwriter Free Writing Prospectus and delivered to a purchaser of a Publicly Offered Certificate was not correctly reflected in such Underwriter Free Writing Prospectus such that it caused the Underwriter Free Writing Prospectus to contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements contained therein, in the light of the circumstances under which they were made, when read together with all other Time of Sale Information not misleading (such Free Writing Prospectus, a “Defective Free Writing Prospectus”), the Underwriter shall notify the Company thereof within one business day after discovery and shall, if requested by the Company.

(i) Prepare a Free Writing Prospectus with Corrective Information that corrects the material misstatement in or omission from the Defective Free Writing Prospectus (such corrected Free Writing Prospectus, a “Corrected Free Writing Prospectus”);

(ii) Deliver the Corrected Free Writing Prospectus to each purchaser of a Publicly Offered Certificate which received the Defective Free Writing Prospectus prior to entering into an agreement to purchase any Publicly Offered Certificates;

(iii) Notify such purchaser in a prominent fashion that the prior agreement to purchase Publicly Offered Certificates has been terminated, and of such purchaser’s rights as a result of termination of such agreement; and

(iv) Provide such purchaser with an opportunity to affirmatively agree to purchase such Publicly Offered Certificates on the terms described in the Corrected Free Writing Prospectus.

(l) The Underwriter covenants with the Company that after the final Prospectus is available the Underwriter shall not distribute any written information concerning the Publicly Offered Certificates that contains Issuer Information to a prospective purchaser of Publicly Offered Certificates unless such information is preceded or accompanied by the final Prospectus.

12. All statements, requests, notices and agreements hereunder shall be in writing or by telegram if promptly confirmed in writing, and shall be sufficient in all respects, if delivered or sent by registered mail to the Underwriter, to the address of the Underwriter, Attention: Registration Department, set forth above; if to the Company, to the address of the Company set forth in the Prospectus, Attention: President.

13. This Agreement shall be binding upon, and inure solely to the benefit of the Underwriter, the Company and, to the extent provided in Section 8 hereof, the officers and directors of the Company and each person who controls the Company or the Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Publicly Offered Certificates from the Underwriter shall be deemed a successor or assign merely by reason of such purchase.

14. Time shall be of the essence of this Agreement.

15. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

16. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

17. The Company is authorized, subject to applicable law, to disclose any and all aspects of this potential transaction that are necessary to support any U.S. federal income tax benefits expected to be claimed with respect to such transaction, and all materials of any kind (including tax opinions and other tax analyses) related to those benefits, without the Underwriter imposing any limitations of any kind.
