(i)

pro rata (based on their respective Class Principal Balances) to each Class of related Subordinate Certificates whose Subordination Level equals or exceeds its initial Subordination Level and the class of Affected Subordinate Certificates having the lowest numerical designation, or

(ii)

if no class of Subordinate Certificates has a Subordination Level equal to or in excess of its initial Subordination Level, to the Class of Affected Subordinate Certificates having the lowest numerical designation up to an amount sufficient to restore its Subordination Level to its initial Subordination Level, and then to the Class of Affected Subordinate Certificates having the next lowest numerical designation, in the same manner.

(g)

All distributions or allocations made with respect to each Class of Certificates on each Distribution Date shall be allocated pro rata among the outstanding Certificates of such Class based on the outstanding principal balance or Notional Amount, as applicable of each such Certificate. Payment shall be made either (1) by check mailed to the address of each Certificateholder as it appears in the Certificate Register on the Record Date immediately prior to such Distribution Date or (2) with respect to the Regular Certificates, by wire transfer of immediately available funds to the account of a Holder at a bank or other entity having appropriate facilities therefor, if such Holder shall have so notified the Securities Administrator in writing by the Record Date immediately prior to such Distribution Date and such Holder is the registered owner of Regular Certificates with an initial principal amount of at least $1,000,000.

(h)

Any amounts remaining in the Certificate Account on any Distribution Date after all allocations and distributions required to be made by this Trust Agreement have been made shall be paid to the Holders of the Class R Certificates with respect to the related REMIC.

Section 3.02

Allocation of Realized Losses and Shortfalls

(a)

Realized Losses.

(i)

On each Distribution Date, Realized Losses realized during the prior calendar month will be allocated to reduce the Class Principal Balances of the related Subordinate Certificates in reverse numerical order, in each case until the Class Principal Balance of each Class of related Subordinate Certificates has been reduced to zero. If the Class Principal Balances of the Subordinate Certificates related to Group 1 and Group 2 or the Subordinate Certificates related to Group 3, Group 4 and Group 5 have been reduced to zero, further Realized Losses on the Mortgage Loans shall be allocated to the related Senior Certificates based on their outstanding Class Principal Balances in each case until the Class Principal Balance has been reduced to zero.

(ii)

If on any Distribution Date, any losses due to the bankruptcy of the related mortgagor, fraud on any party to the related mortgage documents and Special Hazard Losses such as natural disasters, which are not covered by special hazard insurance policies or flood insurance policies (“Special Losses”) are realized during the prior calendar month and the aggregate Class Principal Balance of the (i) Subordinate Certificates related to Loan Group 1 or Loan Group 2 or (ii) Subordinate Certificates related to Loan Group 3, Loan Group 4 or Loan Group 5 have been reduced to zero, and a Realized Loss that is a Special Loss is to be allocated to the certificates senior to such Loan Group or Loan Groups, as the case may be, such loss will be allocated to the most subordinate class of Subordinate Certificates of any Loan Group outstanding until the aggregate class Principal Balance of all Subordinate Certificates was reduced to zero. Thereafter, Special Losses shall be allocated to the Senior Certificates of the related Loan Group.

(iii)

Whenever Realized Losses are required to be allocated to a Class of Certificates, the Realized Loss shall be allocated to Certificates of such Class of the related Loan Group or Loan Groups, as the case may be, based on their respective outstanding principal amounts.

(b)

Interest Shortfall. Notwithstanding anything in the Standard Terms or this Trust Agreement to the contrary, on each Distribution Date, before any distributions are made on the Certificates, any Shortfall with respect to any Mortgage Loan shall be allocated to reduce the Accrued Certificate Interest on each Class of Senior Certificates related to the Loan Group of such Mortgage Loan and each Class of related Subordinate Certificates pro rata, based on the amount of Accrued Certificate Interest otherwise owing to each such Class pursuant to clause (i) of the definition of Accrued Certificate Interest.

(c)

Modification Losses. Notwithstanding anything in the Standard Terms or this Trust Agreement to the contrary, in the event that the Note Rate on a Mortgage Loan is reduced as a result of a modification, waiver or amendment of the terms of such Mortgage Loan, whether agreed to by any Servicer or resulting from a bankruptcy, insolvency or similar proceeding involving the related Borrower, such modification, waiver or amendment shall be disregarded for purposes of calculating the Certificate Rate on any Class of Certificates.

(d)

Subsequent Recoveries. With respect to any Subsequent Recoveries received with respect to a Mortgage Loan, such Subsequent Recoveries will be treated as a principal prepayment. In addition, the Class Principal Balance of each Class of Certificates to which Realized Losses have been allocated will be increased, sequentially in the order of payment priority, by the amount of Subsequent Recoveries, but not by more than the amount of Realized Losses previously allocated to reduce the Class Principal Balance of such Class.

Section 3.03

Crossover Amounts.

(a)

If, as a result of losses on the Mortgage Loans in Loan Group 1 and Loan Group 2, the aggregate Class Principal Balance of the Group 1 and Group 2 Certificates exceeds the outstanding aggregate principal balance of the Mortgage Loans in Loan Group 1 and Loan Group 2 (such class or classes, the related “Affected Senior Certificates”, such Loan Group, the “Undercollateralized Loan Group”), then future principal payments otherwise allocable to the Subordinate Certificates related to Loan Group 1 and Loan Group 2 will be “crossed over” or used to repay principal of the Affected Senior Certificates by increasing the Senior Principal Distribution Amount for the Loan Group related to the Affected Senior Certificates in an amount equal to the lesser of (i) the aggregate amount of principal otherwise payable to the Subordinate Certificates related to Loan Group 1 and Loan Group 2 on such Distribution Date and (ii) the amount required to be paid to the Affected Senior Certificates so that their aggregate Class Principal Balance is equal to the outstanding aggregate principal balance of the Mortgage Loans in Loan Group 1 and Loan Group 2.

(b)

In addition, if, as a result of rapid prepayments, the aggregate Class Principal Balance of the Group 1 and Group 2 Certificates has been reduced to zero and such Senior Certificates are retired, amounts otherwise distributable as principal on each class of Subordinate Certificates related to Loan Group 1 and Loan Group 2 will instead be distributed as principal to the Senior Certificates related to the other Loan Group which remain outstanding, until the Class Principal Balances of the Subordinate Certificates related to Loan Group 1 and Loan Group 2 have been reduced to zero. In order for the distribution priority described in the foregoing sentence to apply on any Distribution Date, it must also be true that either (a) the related Subordinate Percentage for that Distribution Date is less than 200% of such Subordinate Percentage as of the Cut Off Date, or (b) the average outstanding principal balance of the Mortgage Loans in Loan Group 1 and Loan Group 2 that are delinquent 60 days or more (including any such Mortgage Loans in foreclosure or bankruptcy and REO properties) during the most recent three calendar months as a percentage of the related Subordinate Percentage is greater than or equal to 50%.

(c)

If, as a result of losses on the Mortgage Loans in Loan Group 3, Loan Group 4 and Loan Group 5, the aggregate Class Principal Balance of the Group 3, Group 4 and Group 5 Certificates exceeds the outstanding aggregate principal balance of the Mortgage Loans in Loan Group 3, Loan Group 4 and Loan Group 5 (such class or classes, the related “Affected Senior Certificates”), then future principal payments otherwise allocable to the Subordinate Certificates related to Loan Group 3, Loan Group 4 and Loan Group 5 will be “crossed over” or used to repay principal of the Affected Senior Certificates by increasing the Senior Principal Distribution Amount for the Loan Group related to the Affected Senior Certificates in an amount equal to the lesser of (i) the aggregate amount of principal otherwise payable to the Subordinate Certificates related to Loan Group 3, Loan Group 4 and Loan Group 5 on such Distribution Date and (ii) the amount required to be paid to the Affected Senior Certificates so that their aggregate Class Principal Balance is equal to the outstanding aggregate principal balance of the Mortgage Loans in Loan Group 3, Loan Group 4 and Loan Group 5. If on any Distribution Date, there is more than one undercollateralized Loan Group, the distributions described above will be made in proportion to the amounts by which the aggregate Class Principal Balance of the classes of Affected Senior Certificates related to a Loan Group exceeds the principal balance of the Mortgage Loans in such Loan Group. In addition, to the extent the Available Distribution Amount for any Loan Group (without taking into account any cross-over payments from other Loan Groups) is less than the interest and principal then distributable to the related Senior Certificates, the remaining Available Distribution Amount for the other Loan Groups (after payment of all amounts distributable to Senior Certificates related to such Loan Groups) will be reduced pro rata by an aggregate amount equal to such shortfall, and the amount of such reduction will be added to the Available Distribution Amount of the Loan Group experiencing such shortfall.

(d)

In addition, if, as a result of rapid prepayments, the aggregate Class Principal Balance of the Group 3, Group 4 and Group 5 Certificates has been reduced to zero and such Senior Certificates are retired, amounts otherwise distributable as principal on each class of Subordinate Certificates related to Loan Group 3, Loan Group 4 and Loan Group 5 will instead be distributed as principal to the Senior Certificates related to the other Loan Groups which remain outstanding, until the Class Principal Balances of the Subordinate Certificates related to Loan Group 3, Loan Group 4 and Loan Group 5 have been reduced to zero.

The Trust consists primarily of a pool of Mortgage Loans. This Certificate is issued under and is subject to the terms, provisions and conditions of the Trust Agreement and also is subject to certain terms and conditions set forth in the Sale and Servicing Agreements, to which Sale and Servicing Agreements the Holder of this Certificate, by virtue of the acceptance hereof assents and by which such Certificateholder is bound.

As provided in the Trust Agreement, withdrawals from the Collection Accounts, the Certificate Account and related accounts shall be made from time to time for purposes other than distributions to Holders, such purposes including reimbursement of Advances made, or certain expenses incurred, with respect to the Mortgage Loans and administration of the Trust.

The Securities Administrator may charge the Certificateholder a fee for any payment made by wire transfer. Final distribution on the Certificates will be made only upon surrender of the Certificates at the offices of the Certificate Registrar set forth in the notice of such final distribution.

The Trust Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Securities Administrator, the Trustee, the Master Servicer and the Custodian and the rights of the Certificateholders under the Trust Agreement at any time by the Depositor, the Master Servicer, the Securities Administrator and the Trustee with the consent of the Certificateholders entitled to at least 51% of the Voting Rights.

The Trust Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Certificateholders.

The Certificates are issuable in fully registered form only, without coupons, in denominations specified in the Trust Agreement. As provided in the Trust Agreement and subject to any limitations on transfer of this Certificate by a Depository or its nominee and certain limitations set forth in the Trust Agreement, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the principal Corporate Trust Office of the Securities Administrator or such other offices or agencies appointed by the Securities Administrator for that purpose and such other locations provided in the Trust Agreement, duly endorsed by or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to, the Trustee and the Certificate Registrar duly executed by the Certificateholder hereof, or such Certificateholder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in the same aggregate Certificate Principal Balance will be issued to the designated transferee or transferees.

The Depositor, the Securities Administrator, the Trustee and the Certificate Registrar and any agent of the Depositor, the Securities Administrator, the Trustee or the Certificate Registrar may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Securities Administrator, the Trustee, the Certificate Registrar or any such agent shall be affected by notice to the contrary.

The obligations created by the Trust Agreement will terminate upon payment to the Certificateholders of all amounts held in the Collection Accounts and the Certificate Account required to be paid to the Certificateholders pursuant to the Trust Agreement, following the earlier of: (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust or the disposition of all property acquired upon foreclosure of any such Mortgage Loan and (ii) the repurchase of all the assets of the Trust by the Master Servicer or at the direction of the Depositor, in accordance with the Trust Agreement when the aggregate Scheduled Principal Balance of the Mortgage Loans equals 10% or less of the aggregate Scheduled Principal Balance of the Mortgage Loans as of the Cut-Off Date.

Unless the certificate of authentication hereon has been executed by the Certificate Registrar, by manual signature, this Certificate shall not be entitled to any benefit under the Trust Agreement or be valid for any purpose.

THIS CERTIFICATE AND THE TRUST AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS (OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

THIS CERTIFIES THAT:

[GOLDMAN, SACHS & CO] [WELLS FARGO BANK N.A.]

is the registered owner of the Percentage Interest evidenced by this Certificate in the Class R Certificates (the “Class R Certificates”) issued by the trust (the “Trust”) created pursuant to a Master Servicing and Trust Agreement, dated as specified above (the “Trust Agreement”), among GS Mortgage Securities Corp., as depositor (hereinafter the “Depositor,” which term includes any successor entity under the Trust Agreement), U.S. Bank National Association, as trustee (the “Trustee”), JPMorgan Chase Bank, as custodian (the “Custodian”) and Wells Fargo Bank, N.A. as the securities administrator and master servicer (in such capacities, respectively, the “Securities Administrator” and “Master Servicer”), a summary of certain of the pertinent provisions of which is set forth hereafter. The Trust consists primarily of a pool of Mortgage Loans. This Certificate is issued under and is subject to the terms, provisions and conditions of the Trust Agreement and also is subject to certain terms and conditions set forth in the Sale and Servicing Agreements, to which Sale and Servicing Agreements the Holder of this Certificate, by virtue of the acceptance hereof assents and by which such Certificateholder is bound.

Distributions on this Certificate (including the final distribution on this Certificate) will be made out of the related Available Distribution Amount, to the extent and subject to the limitations set forth in the Trust Agreement, on the 25^th day of each month, or if such day is not a Business Day, the next succeeding Business Day, beginning in December 2004 (each, a “Distribution Date”), commencing on the first Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the Interest Accrual Period related to such Distribution Date (the “Record Date”). All sums distributable on this Certificate are payable in the coin or currency of the United States of America as at the time of payment is legal tender for the payment of public and private debts.

Distributions on this Certificate will be paid in accordance with the terms of the Trust Agreement. Distributions allocated to this Certificate on any Distribution Date will be an amount equal to this Certificate’s Percentage Interest of the Available Distribution Amount to be distributed on this Class of Certificates as of such Distribution Date, with a final distribution to be made upon retirement of this Certificate as set forth in the Trust Agreement.

This Certificate is one of a duly authorized issue of Certificates designated as Mortgage Pass-Through Certificates, Series 2004-14 (herein called the “Certificates”), and representing a Percentage Interest in the Class of Certificates specified on the face hereof equal to the quotient, expressed as a percentage, obtained by dividing the denomination of this Certificate specified on the face hereof by the aggregate Certificate Principal Balance of the Class R Certificate. The Certificates are issued in multiple Classes designated as specifically set forth in the Trust Agreement. This Certificate will evidence in the aggregate [99.99] [0.01]% of the balance of the Class R Certificate.

The Certificates are limited in right of payment to certain collections and recoveries in respect of the Mortgage Loans, all as more specifically set forth in the Trust Agreement. As provided in the Trust Agreement, withdrawals from the Collection Accounts, the Master Servicing Account, the Certificate Account and related accounts shall be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of Advances made, or certain expenses incurred, with respect to the Mortgage Loans and administration of the Trust.

All distributions or allocations made with respect to each Class on any Distribution Date shall be allocated pro rata among the outstanding Certificates of such Class based on the Certificate Principal Balance of each such Certificate. Payment shall be made by check mailed to the address of each Certificateholder as it appears in the Certificate Register on the Record Date immediately prior to such Distribution Date. Final distribution on the Certificates will be made only upon surrender of the Certificates at the offices of the Certificate Registrar set forth in the notice of such final distribution.

Elections will be made to treat the segregated portions of the Trust as multiple real estate mortgage investment conduits (each, a “REMIC”) under the Internal Revenue Code of 1986, as amended (the “Code”). Assuming that the election is made properly and that certain qualification requirements concerning the Mortgage Loans and the Certificates are met, the Holder of this Certificate will be treated for federal income tax purposes as the beneficial owner of the “residual interest” in each REMIC. Accordingly, the Holder of this Class R Certificate will be subject to tax on its pro rata share of the taxable income or net loss on such Holder’s “residual interest” in each REMIC. The requirement that the Holder of this Class R Certificate report its pro rata share of such income or loss will continue until there are no Certificates of any Class outstanding.

Pursuant to (and subject to the limitations set forth in) the Trust Agreement, the Securities Administrator or one of its affiliates, as agent of each REMIC (the “Tax Matters Person” or “TMP”), will provide each Holder of a Class R Certificate with information sufficient to enable such Certificateholder to prepare (i) its federal income tax and information returns and (ii) any reports required by the Code regarding the Certificates, except where such information is provided to each such Certificateholder by the Trustee pursuant to the Trust Agreement. As the holder of the residual interest in each REMIC, the Holder of a Class R Certificate will have continuing administrative rights and obligations generally similar to those of a partner with respect to its partnership. Such rights and obligations principally concern the REMIC’s federal income tax and information returns and the representation of the REMIC in administrative or judicial proceedings involving the Internal Revenue Service. The TMP, however, will act on behalf of the Holders of the Class R Certificate as each REMIC’s representative for such proceedings. The REMIC’s federal tax and information returns will be prepared by the TMP, and signed and filed by the Trustee. Pursuant to the Trust Agreement, if the TMP is unable for any reason to fulfill its duties as TMP, then the Holder of the largest Percentage Interest of the Class R Certificate, without compensation, shall become the successor TMP for each REMIC.

By accepting this Certificate, the Holder of this Certificate agrees to be bound by the provisions of the Trust Agreement, and in particular, agrees that it shall (i) take any action required by the Code or Treasury regulations thereunder in order to create or maintain the REMIC status of any REMIC and (ii) refrain from taking any action that could endanger such status.

The Certificates are issuable in fully registered form only, without coupons, in denominations specified in the Trust Agreement. As provided in the Trust Agreement and subject to certain limitations set forth in the Trust Agreement, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the principal Corporate Trust Office of the Securities Administrator or such other offices or agencies appointed by the Securities Administrator for that purpose and such other locations provided in the Trust Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to, the Trustee and the Certificate Registrar duly executed by the Certificateholder hereof, or such Certificateholder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in the same aggregate Certificate Principal Balance will be issued to the designated transferee or transferees.

No transfer of any Class R Certificate shall be made unless that transfer is made pursuant to an effective registration statement under the Securities Act of 1933, as amended (the ”Act”) and effective registration or qualification under applicable state certificates laws, or is made in a transaction that does not require such registration or qualification. In the event that a transfer is to be made without registration or qualification under the Act and applicable state certificates laws, the Trustee shall require that the transferee certify as to facts that, if true, would mean that the proposed transferee is a Qualified Institutional Buyer. Neither the Depositor nor the Trustee is obligated to register or qualify any of the Class R Certificate under the Act or any other certificates law or to take any action not otherwise required under the Trust Agreement to permit the transfer of such Certificates without such registration or qualification. Any such Certificateholder desiring to effect such transfer shall, and does hereby agree to, indemnify the Depositor and the Trustee against any liability that may result if the transfer is not exempt from registration under the Act and all applicable state certificates laws or is not made in accordance with such federal and state laws.

Notwithstanding anything herein to the contrary, any purported transfer of a Class R Certificate to or on behalf of a Plan Investor shall be null and void.

In addition, the Trustee shall not register any transfer of a Class R Certificate (including any beneficial interest therein) to a Disqualified Organization. In addition, no Class R Certificate (or any beneficial interest therein) may be transferred unless the proposed transferee thereof provides the Trustee with a Residual Transferee Affidavit, which is an affidavit of the proposed transferee substantially in the form attached as Exhibit F to the Standard Terms, and the proposed transferor provides a certificate substantially in the form attached as Exhibit G to the Standard Terms. Notwithstanding the fulfillment of the prerequisites described above, the Trustee may refuse to recognize any transfer to the extent necessary to avoid a risk of (i) disqualification of any REMIC created pursuant to Section 2.03 of the Trust Agreement as a REMIC or (ii) the imposition of a tax upon any REMIC. Any attempted transfer in violation of the foregoing restrictions shall be null and void and shall not be recognized by the Trustee.

If a tax or a reporting cost is borne by the REMIC as a result of the transfer of a Class R Certificate (or any beneficial interest therein) in violation of the restrictions set forth herein and in the Trust Agreement, the Trustee shall pay such tax or reporting cost with amounts that otherwise would have been paid to the transferee of the Class R Certificate (or beneficial interest therein). In that event, neither the transferee nor the transferor shall have any right to seek repayment of such amounts from the Depositor or the Trustee, the Trust, any REMIC, or any other Holders, and none of such parties shall have any liability for payment of any such tax or reporting cost.

The obligations created by the Trust Agreement will terminate upon payment to the Certificateholders of all amounts held in the Collection Accounts and the Certificate Account required to be paid to the Certificateholders pursuant to the Trust Agreement, following the earlier of: (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust or the disposition of all property acquired upon foreclosure of any such Mortgage Loan and (ii) the repurchase of all the assets of the Trust by a Servicer identified in the Trust Agreement or the Depositor, in accordance with the Trust Agreement when the aggregate Scheduled Principal Balance of the Mortgage Loans equals 10% or less of the aggregate Scheduled Principal Balance of the Mortgage Loans as of the Cut-Off Date. Written notice of termination will be given to each Certificateholder, and the final distribution will be made only upon surrender and cancellation of the Certificates at an office or agency appointed by the Trustee which will be specified in the notice of termination.

Any such repurchase of Mortgage Loans and property acquired in respect of the Mortgage Loans shall be made at the Termination Price.

The Trustee has executed this Certificate on behalf of the Trust as Trustee under the Trust Agreement, and the Trustee shall be liable hereunder only in respect of the assets of the Trust.

Capitalized terms used herein and not otherwise defined shall have the meaning given them in the Trust Agreement.

In the event that the terms of this Certificate conflict with the terms of the Trust Agreement, the terms of the Trust Agreement shall control.

IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly executed.
