            THIS TRUST AGREEMENT, dated as of April 1, 2004 (this "Trust
Agreement"), is hereby executed between GS MORTGAGE SECURITIES CORP., a Delaware
corporation (the "Depositor"), and JPMORGAN CHASE BANK, as trustee (in such
capacity, the "Trustee") and custodian (in such capacity, the "Custodian").

                              PRELIMINARY STATEMENT

            The Depositor is duly authorized to form GSR Mortgage Loan Trust
2004-5 as a trust (the "Trust") to issue a series of securities with an
aggregate initial outstanding principal balance of $549,788,986 to be known as
the Mortgage Pass-Through Certificates, Series 2004-5 (the "Certificates"). The
Trust is formed by this Trust Agreement, which fully incorporates by reference
the Standard Terms to Trust Agreement April 2004 Edition (the "Standard Terms").
The Certificates in the aggregate evidence the entire beneficial ownership in
the Trust. The Certificates consist of the 16 classes set forth in Section
2.03(d) herein.

            Pursuant to Section 10.01 of the Standard Terms, the Trustee will
make an election to treat all of the assets of the Trust as three real estate
mortgage investment conduits (each, a "REMIC" and, individually, "REMIC I" and
"REMIC II," and "REMIC III") for federal income tax purposes. The "startup day"
of each REMIC for purposes of the REMIC Provisions is the Closing Date.

            NOW, THEREFORE, in consideration of the mutual promises, covenants,
representations and warranties hereinafter set forth, the Depositor, the Trustee
and the Custodian agree as follows:

each such entity, with respect to the Certificates. The Depositor, the Trustee
and the Custodian agree to observe and perform such prescribed duties,
responsibilities and obligations, pursuant to the terms and conditions thereof
and of this Trust Agreement, and acknowledge that, except to the extent
inconsistent with the provisions of this Trust Agreement, the Standard Terms are
and shall be a part of this Trust Agreement to the same extent as if set forth
herein in full.

            Pursuant to Section 2.02(f) of the Standard Terms, the Depositor
acknowledges the appointment of the Custodian and agrees to deliver, or cause to
be delivered, to the Custodian all Mortgage Loan documents that are to be
included in the Trustee Mortgage Loan File for each Mortgage Loan. The Depositor
and the Custodian acknowledge that, pursuant to the existing Custodial
Agreements entered into between the Custodian and predecessors in interest of
the Depositor, the Custodian previously acted as custodian for such predecessors
in interest and that in connection with the formation of the Trust, the
Depositor will assign each Custodial Agreement to the Trustee and cause a

                  (3) third, to the Class 2A1 Certificates, as principal, up to
            the Senior Principal Distribution Amount for Loan Group 2, until the

            Certificates, Accrued Certificate Interest thereon;

                  (2) second, to the Class 3A1 Certificates, as principal, up to

            (i) to the Class B1 Certificates, Accrued Certificate Interest on
      such Class;

            (ii) to the Class B1 Certificates, as principal, their pro rata

            (v) to the Class B3 Certificates, Accrued Certificate Interest on
      such Class;

            (vi) to the Class B3 Certificates, as principal, their pro rata

            (vii) to the Class B4 Certificates, Accrued Certificate Interest on
      such Class;

            (viii) to the Class B4 Certificates, as principal, their pro rata
      share (based on the Class Principal Balance thereof) of the Subordinate
      Principal Distribution Amount until the Class Principal Balance thereof
      has been reduced to zero;

            (ix) to the Class B5 Certificates, Accrued Certificate Interest on
      such Class;

            (x) to the Class B5 Certificates, as principal, their pro rata share
      (based on the Class Principal Balance thereof) of the Subordinate

            (xi) to the Class B6 Certificates, Accrued Certificate Interest on
      such Class;

            (xii) to the Class B6 Certificates, as principal, their pro rata
      share (based on the Class Principal Balance thereof) of the Subordinate
      Principal Distribution Amount until the Class Principal Balance thereof
      has been reduced to zero;

            (xiii) to each Class of Certificates in order of seniority (and
      among classes of Senior Certificates related to a Loan Group, pro rata,
      based on the amount of unreimbursed Realized Losses allocated to such
      Classes), up to the amount of unreimbursed Realized Losses allocated to
      that Class, if any (unless the allocation of Realized Losses has reduced
      any Class of Certificates to zero on a previous Distribution Date, in
      which case no amounts will be reimbursed to that Class); provided,
      however, that any amounts distributed pursuant to this paragraph (b)(xiii)
      will not cause a further reduction in the Class Principal Balance of any
      Class of Certificates; and

            (xiv) at such time as all other Classes of Certificates have been
      paid in full and all Realized Losses previously allocated have been
      reimbursed in full (unless the allocation of Realized Losses has reduced
      any Class of Certificates to zero on a previous Distribution Date, in
      which case no amounts will be reimbursed to that Class), all remaining
      amounts to the Residual Certificates with respect to the Class R-I
      Interest.

            (c) Notwithstanding subsection (b) above, 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 Certificates (such
Class, the "Affected Subordinate Certificates"), the aggregate portion of the
Principal Prepayment Amount otherwise payable on such Distribution Date to
Classes of Subordinate Certificates will be allocated as follows:

            (i) pro rata (based on their respective Class Principal Balances) to
      each Class of 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.

            (d) 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 Trustee 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. The Trustee may charge the Holder 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.

            (e) 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 (other than Excess
      Special Losses) realized during the prior calendar month will be allocated
      to reduce the Class Principal Balances of the Subordinate Certificates in
      reverse numerical order, in each case until the Class Principal Balance of
      each such Class has been reduced to zero. If the Class Principal Balances
      of all of the Subordinate Certificates have been reduced to zero, further
      Realized Losses (other than Excess Special Losses) on the Mortgage Loans
      shall be allocated to the Senior Certificates related to the Loan Group in
      which such Realized Losses occurred based on their outstanding Class
      Principal Balances, in each case until the Class Principal Balance has
      been reduced to zero; provided, however, that Realized Losses (other than
      Excess Special Losses) otherwise allocable to the Class 1A1 Certificates
      shall be allocated to the Class 1A2 Certificates to reduce the Certificate
      Balance of such Class until such Certificate Balance has been reduced to
      zero, and thereafter such Realized Losses shall be allocated to the Class
      1A1 Certificates to reduce the Certificate Balance of such Class until
      such Certificate Balance has been reduced to zero.

            (ii) On any Distribution Date, any Excess Special Losses that are
      realized during the prior calendar month will be allocated to all Classes
      of Senior Certificates related to the Loan Group in which such losses
      occurred, and the Subordinate Certificates pro rata, based on, with
      respect to such Classes of Senior Certificates, their respective Class
      Principal Balances and, with respect to the Subordinate Certificates, the
      related Group Subordinate Amount, respectively.

            (iii) Whenever Realized Losses or Excess Special Losses are required
      to be allocated to a Class of Certificates, the Realized Loss or Excess
      Special Loss shall be allocated to Certificates of such Class 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, 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 Subordinate Certificates pro rata, based on the amount of
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, on any Distribution Date, the aggregate Class Principal
Balance of the Group 1, Group 2 or Group 3 Certificates exceeds the outstanding
aggregate principal balance of the Mortgage Loans in the related Loan Group
(such class or classes, the "Affected Senior Certificates", such Loan Group, the
"Undercollateralized Loan Group"), then future principal payments otherwise
allocable to the Subordinate Certificates 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
certificates in an amount equal to the lesser of (i) the aggregate amount of
principal otherwise payable to the Subordinate Certificates 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 their related Loan Group.
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.

            (b) 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.

            (c) In addition, if the aggregate Class Principal Balance of the
Group 1, Group 2 or Group 3 Certificates has been reduced to zero and such
Senior Certificates are retired, amounts otherwise distributable as principal on
each class of Subordinate Certificates will instead be distributed as principal
to the Senior Certificates related to other Loan Groups which remain
outstanding, until the Class Principal Balances of the Subordinate Certificates
have been reduced to zero; provided, however, that either (a) the Subordinate
Percentage for the Loan Groups in the aggregate 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 the related Loan
Group that are delinquent 60 days or more (including 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%.

            Section 4.03 Redemption of Certificates. Notwithstanding anything to
the contrary in Section 9.02 of the Standard Terms, the obligations created by
the Trust Agreement will terminate upon payment to the Certificateholders of all
amounts held in the Collection Account, the Certificate Account and the REMIC I
Distribution 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 of the
assets of the Trust by Countrywide Servicing upon the date on which the
aggregate Scheduled Principal Balance of the Mortgage Loans is equal to or less
than 10% of the aggregate Scheduled Principal Balance of such Mortgage Loans as
of the Cut-Off Date (and if not exercised by Countrywide Servicing within a
period of five Business Days from the first date on which such condition is
satisfied, by the Depositor). Written notice of termination shall be given to
each Certificateholder, and the final distribution shall 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
repurchase of the assets of the Trust pursuant to this Section 4.03 shall be
made at a price equal to the Termination Price.

            Section 4.04 Securities Laws Restrictions. Each of the Class B4,
Class B5 and Class B6 Certificates is a Class of Junior Subordinate Certificates
subject to the restrictions on transfer contained in Section 5.05(a) of the
Standard Terms. The Class R Certificates are Residual Certificates subject to
Section 5.05(c) of the Standard Terms.

THIS CERTIFIES THAT:

                                   CEDE & CO.

is the registered owner of the Percentage Interest evidenced by this
Certificate in the Class 1A1 Certificates (the "Class 1A1 Certificates")
issued by the trust (the "Trust") created pursuant to a Trust Agreement,
dated as specified above (the "Trust Agreement"), between GS Mortgage
Certificates Corp., as depositor (hereinafter the "Depositor," which term
includes any successor entity under the Trust Agreement) and JPMorgan Chase
Bank, as trustee (in such capacity, the "Trustee") and custodian (in such
capacity, the "Custodian"), 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 Agreements and the
Servicing Agreements, to which the Sale Agreements and the 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 25th day of each month, or if such day is not a Business Day,
the next succeeding Business Day, beginning in May 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

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, the Sale Agreements and the Servicing
Agreements. Distributions allocated to this Certificate on any Distribution Date
will be an amount equal to this Certificate's Percentage Interest of the related
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 2004-5 (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 all the
Class 1A1 Certificates. The Certificates are issued in multiple Classes
designated as specifically set forth in the Trust Agreement. The Certificates
will evidence in the aggregate 100% of the beneficial ownership of the Trust.

            Realized Losses and interest shortfalls on the Mortgage Loans shall
be allocated among the Classes of Certificates on the applicable Distribution
Date in the manner set forth in the Trust Agreement. To the extent provided in
the Trust Agreement, with respect to Realized Losses and interest shortfalls,
the Subordinate Certificates will be subordinated to the Senior Certificates and
each of the Subordinate Certificates will be subordinated to each of the other
Subordinate Certificates with a lower numerical class designation, if any. All
Realized Losses and interest shortfalls on the Mortgage Loans allocated to any
Class of Certificates will be allocated pro rata among the outstanding
Certificates of such Class, as described in the Trust Agreement.

            The Certificates are limited in right of payment to certain
collections and recoveries respecting 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 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.

            All distributions or allocations made with respect to each Class on
any Distribution Date shall be allocated in accordance with the Trust Agreement.
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
Certificates other than the Residual Certificates, by wire transfer of
immediately available funds to the account of a Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder
shall have so notified the Trustee in writing by the Record Date immediately
prior to such Distribution Date and such Certificateholder is the registered
owner of an initial Certificate Principal Balance or Notional Amount of at least
$1,000,000. The Trustee 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 Trustee and the Custodian and the rights of
the Certificateholders under the Trust Agreement at any time by the Depositor,
the Trustee and the Custodian with the consent of the Certificateholders
entitled to at least 51% of the Voting Rights. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Certificateholder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent is made upon this Certificate. 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 Trustee or such other offices or
agencies appointed by the Trustee 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.

            As provided in the Trust Agreement and subject to certain
limitations therein set forth, this Certificate is exchangeable for a new
Certificate of the same Class in the same denomination. 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 that may be imposed in connection with any transfer or exchange of
Certificates.

            The Depositor, the Trustee, the Custodian and the Certificate
Registrar and any agent of the Depositor, the Trustee, the Custodian 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
Trustee, the Custodian, 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 Countrywide Home Loans Servicing LP 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.

            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 CONSTRUED IN
ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK.

            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 defined herein shall have the
meaning assigned to 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.

Bank, as trustee (in such capacity, the "Trustee") and custodian (in such
capacity, the "Custodian"), 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 Agreements and the

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

capacity, the "Custodian"), 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

immediately available funds to the account of a Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder

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 Trustee and the Custodian and the rights of
the Certificateholders under the Trust Agreement at any time by the Depositor,

same aggregate Certificate Principal Balance will be issued to the designated
transferee or transferees.

            As provided in the Trust Agreement and subject to certain
limitations therein set forth, this Certificate is exchangeable for a new
Certificate of the same Class in the same denomination. 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 that may be imposed in connection with any transfer or exchange of
Certificates.

            The Depositor, the Trustee, the Custodian and the Certificate
Registrar and any agent of the Depositor, the Trustee, the Custodian 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
Trustee, the Custodian, 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 Countrywide Home Loans Servicing LP 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.

            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 CONSTRUED IN
ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK.

            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 defined herein shall have the
meaning assigned to 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.

                                   CEDE & CO.

is the registered owner of the Percentage Interest evidenced by this
Certificate in the Class 3A2 Certificates (the "Class 3A2 Certificates")
issued by the trust (the "Trust") created pursuant to a Trust Agreement,
dated as specified above (the "Trust Agreement"), between GS Mortgage
Certificates Corp., as depositor (hereinafter the "Depositor," which term
includes any successor entity under the Trust Agreement) and JPMorgan Chase
Bank, as trustee (in such capacity, the "Trustee") and custodian (in such
capacity, the "Custodian"), 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 Agreements and the
Servicing Agreements, to which the Sale Agreements and the 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 25th day of each month, or if such day is not a Business Day,
the next succeeding Business Day, beginning in May 2004 (each, a "Distribution
Date"), commencing on the first Distribution Date specified above, to the Person

debts.

            Distributions on this Certificate will be paid in accordance with
the terms of the Trust Agreement, the Sale Agreements and the Servicing
Agreements. Distributions allocated to this Certificate on any Distribution Date
will be an amount equal to this Certificate's Percentage Interest of the related
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

            This Certificate is one of a duly authorized issue of Certificates

Certificates specified on the face hereof equal to the quotient, expressed as a

            Realized Losses and interest shortfalls on the Mortgage Loans shall
be allocated among the Classes of Certificates on the applicable Distribution
Date in the manner set forth in the Trust Agreement. To the extent provided in
the Trust Agreement, with respect to Realized Losses and interest shortfalls,
the Subordinate Certificates will be subordinated to the Senior Certificates and
each of the Subordinate Certificates will be subordinated to each of the other
Subordinate Certificates with a lower numerical class designation, if any. All
Realized Losses and interest shortfalls on the Mortgage Loans allocated to any
Class of Certificates will be allocated pro rata among the outstanding
Certificates of such Class, as described in the Trust Agreement.

            The Certificates are limited in right of payment to certain
collections and recoveries respecting 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 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.

            All distributions or allocations made with respect to each Class on
any Distribution Date shall be allocated in accordance with the Trust Agreement.
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
Certificates other than the Residual Certificates, by wire transfer of
immediately available funds to the account of a Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder
shall have so notified the Trustee in writing by the Record Date immediately
prior to such Distribution Date and such Certificateholder is the registered
owner of an initial Certificate Principal Balance or Notional Amount of at least
$1,000,000. The Trustee 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 Trustee and the Custodian and the rights of
the Certificateholders under the Trust Agreement at any time by the Depositor,
the Trustee and the Custodian with the consent of the Certificateholders
entitled to at least 51% of the Voting Rights. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Certificateholder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent is made upon this Certificate. 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 Trustee or such other offices or
agencies appointed by the Trustee 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.

            As provided in the Trust Agreement and subject to certain
limitations therein set forth, this Certificate is exchangeable for a new
Certificate of the same Class in the same denomination. 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 that may be imposed in connection with any transfer or exchange of
Certificates.

            The Depositor, the Trustee, the Custodian and the Certificate
Registrar and any agent of the Depositor, the Trustee, the Custodian 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
Trustee, the Custodian, 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 Countrywide Home Loans Servicing LP 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.

            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 CONSTRUED IN
ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK.

            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 defined herein shall have the
meaning assigned to 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.

trustee (in such capacity, the "Trustee") and custodian (in such capacity,
the "Custodian"), 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

Certificates of such Class, as described in the Trust Agreement.

            The Certificates are limited in right of payment to certain

$1,000,000. The Trustee 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 Trustee and the Custodian and the rights of
the Certificateholders under the Trust Agreement at any time by the Depositor,
the Trustee and the Custodian with the consent of the Certificateholders
entitled to at least 51% of the Voting Rights. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Certificateholder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent is made upon this Certificate. 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

same aggregate Certificate Principal Balance will be issued to the designated
transferee or transferees.

            As provided in the Trust Agreement and subject to certain
limitations therein set forth, this Certificate is exchangeable for a new
Certificate of the same Class in the same denomination. 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 that may be imposed in connection with any transfer or exchange of
Certificates.

            The Depositor, the Trustee, the Custodian and the Certificate
Registrar and any agent of the Depositor, the Trustee, the Custodian 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
Trustee, the Custodian, 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 Countrywide Home Loans Servicing LP 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.

            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 CONSTRUED IN
ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK.

            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 defined herein shall have the
meaning assigned to 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.

trustee (in such capacity, the "Trustee") and custodian (in such capacity,
the "Custodian"), 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 Agreements and the
Servicing Agreements, to which the Sale Agreements and the Servicing
Agreements the Holder of this Certificate, by virtue of the acceptance hereof

Amount, to the extent and subject to the limitations set forth in the Trust
Agreement, on the 25th day of each month, or if such day is not a Business Day,

other entity having appropriate facilities therefor, if such Certificateholder
shall have so notified the Trustee in writing by the Record Date immediately
prior to such Distribution Date and such Certificateholder is the registered
owner of an initial Certificate Principal Balance or Notional Amount of at least

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

limitations therein set forth, this Certificate is exchangeable for a new
Certificate of the same Class in the same denomination. 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 that may be imposed in connection with any transfer or exchange of
Certificates.

successor entity under the Trust Agreement) and JPMorgan Chase Bank, as
trustee (in such capacity, the "Trustee") and custodian (in such capacity,
the "Custodian"), 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 Agreements and the
Servicing Agreements, to which the Sale Agreements and the 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 25th day of each month, or if such day is not a Business Day,
the next succeeding Business Day, beginning in May 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

debts.

            Distributions on this Certificate will be paid in accordance with

Agreements. Distributions allocated to this Certificate on any Distribution Date
will be an amount equal to this Certificate's Percentage Interest of the related

of this Certificate to it is being made in reliance on Rule 144A and (C) is
acquiring this Certificate for its own account or for the account of a Qualified
Institutional Buyer, as the case may be and (2) it understands that this

may not be reoffered, resold, or otherwise transferred except (A) to person who
the Holder reasonably believes is a Qualified Institutional Buyer in a

all applicable state securities laws.

            This Certificate is one of a duly authorized issue of Certificates
designated as Mortgage Pass-Through Certificates, Series 2004-5 (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 all the
Class B6 Certificates. The Certificates are issued in multiple Classes
designated as specifically set forth in the Trust Agreement. The Certificates
will evidence in the aggregate 100% of the beneficial ownership of the Trust.

            Realized Losses and interest shortfalls on the Mortgage Loans shall
be allocated among the Classes of Certificates on the applicable Distribution
Date in the manner set forth in the Trust Agreement. To the extent provided in
the Trust Agreement, with respect to Realized Losses and interest shortfalls,
the Subordinate Certificates will be subordinated to the Senior Certificates and
each of the Subordinate Certificates will be subordinated to each of the other
Subordinate Certificates with a lower numerical class designation, if any. All
Realized Losses and interest shortfalls on the Mortgage Loans allocated to any
Class of Certificates will be allocated pro rata among the outstanding
Certificates of such Class, as described in the Trust Agreement.

            The Certificates are limited in right of payment to certain
collections and recoveries respecting 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 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.

            All distributions or allocations made with respect to each Class on
any Distribution Date shall be allocated in accordance with the Trust Agreement.
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) by wire transfer of
immediately available funds to the account of a Certificateholder at a bank or
other entity having appropriate facilities therefor, if such Certificateholder
shall have so notified the Trustee in writing by the Record Date immediately
prior to such Distribution Date and such Certificateholder is the registered
owner of an initial Certificate Principal Balance or Notional Amount of at least
$1,000,000. The Trustee 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 Trustee and the Custodian and the rights of
the Certificateholders under the Trust Agreement at any time by the Depositor,
the Trustee and the Custodian with the consent of the Certificateholders
entitled to at least 51% of the Voting Rights. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Certificateholder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent is made upon this Certificate. 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 Trustee or such other offices or
agencies appointed by the Trustee 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.

            As provided in the Trust Agreement and subject to certain
limitations therein set forth, this Certificate is exchangeable for a new
Certificate of the same Class in the same denomination. 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 that may be imposed in connection with any transfer or exchange of
Certificates.

            The Depositor, the Trustee, the Custodian and the Certificate
Registrar and any agent of the Depositor, the Trustee, the Custodian 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
Trustee, the Custodian, 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 Countrywide Home Loans Servicing LP 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.

            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 CONSTRUED IN
ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK.

            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 defined herein shall have the
meaning assigned to 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.

         MORTGAGE PARTICIPATION PASS THROUGH CERTIFICATES, SERIES 2004-5
                               CLASS R CERTIFICATE

      evidencing a beneficial ownership interest in a Trust consisting of the
      entire beneficial ownership of a pool of certain hybrid adjustable-rate
      single family, fully amortizing, first lien Mortgage Loans formed and
      sold by

                          GS MORTGAGE SECURITIES CORP.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN, AND IS
NOT GUARANTEED BY, GS MORTGAGE SECURITIES CORP., THE SERVICERS, THE TRUSTEE,
THE CUSTODIAN OR ANY OF THEIR AFFILIATES.  NEITHER THIS CERTIFICATE NOR THE
UNDERLYING MORTGAGE LOANS ARE GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF
THE UNITED STATES.

THIS CERTIFIES THAT:

                              [GOLDMAN, SACHS & CO]

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 Trust Agreement, dated as
specified above (the "Trust Agreement"), between GS Mortgage Certificates
Corp., as depositor (hereinafter the "Depositor," which term includes any
successor entity under the Trust Agreement) and JPMorgan Chase Bank, as
trustee (in such capacity, the "Trustee") and custodian (in such capacity,
the "Custodian"), 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 Agreements and the
Servicing Agreements, to which the Sale Agreements and the 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 25th day of each month, or if such day is not a Business Day,
the next succeeding Business Day, beginning in May 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 2004-5 (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 100% of the balance of the Class R Certificate.

            Realized Losses and interest shortfalls on the Mortgage Loans shall
be allocated among the Classes of Certificates on the applicable Distribution
Date in the manner set forth in the Trust Agreement. To the extent provided in
the Trust Agreement, with respect to Realized Losses and interest shortfalls,
the Subordinate Certificates will be subordinated to the Senior Certificates and
each of the Subordinate Certificates will be subordinated to each of the other
Subordinate Certificates with a lower numerical class designation, if any. All
Realized Losses and interest shortfalls on the Mortgage Loans allocated to any
Class of Certificates will be allocated pro rata among the outstanding
Certificates of such Class, as described in the Trust Agreement.

            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 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 three 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 Trustee 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 Trust Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Depositor, the Trustee and the Custodian and the rights of
the Certificateholders under the Trust Agreement at any time by the Depositor,
the Trustee and the Custodian with the consent of the Certificateholders
entitled to at least 51% of the Voting Rights. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Certificateholder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange herefor or in lieu hereof whether or not
notation of such consent is made upon this Certificate. 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 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 Trustee or such other offices or
agencies appointed by the Trustee 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.

            As provided in the Trust Agreement and subject to certain
limitations therein set forth, this Certificate is exchangeable for a new
Certificate of the same Class in the same denomination. 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 that may be imposed in connection with any transfer or exchange of
Certificates.

            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 REMIC I, REMIC II or REMIC III 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 Depositor, the Trustee, the Custodian and the Certificate
Registrar and any agent of the Depositor, the Trustee, the Custodian 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
Trustee, the Custodian, 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 Countrywide Home Loans Servicing LP 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.

            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 CONSTRUED IN
ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK.

            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.
