                         POOLING AND SERVICING AGREEMENT

         Pooling and Servicing Agreement dated as of March 1, 2002, among
Structured Asset Mortgage Investments Inc., a Delaware corporation, as seller
(the "Seller"), Bank One, National Association, a national banking association,
not in its individual capacity but solely as trustee (the "Trustee"), Wells
Fargo Bank Minnesota, National Association, as master servicer (in such
capacity, the "Master Servicer") and as securities administrator (in such
capacity, the "Securities Administrator"), and EMC Mortgage Corporation ("EMC").

                              PRELIMINARY STATEMENT

         On or prior to the Closing Date, the Seller acquired the Mortgage Loans
from EMC. On the Closing Date, the Seller will sell the Mortgage Loans and
certain other property to the Trust Fund and receive in consideration therefor
Certificates evidencing the entire beneficial ownership interest in the Trust
Fund.

         The Trustee on behalf of the Trust shall make an election for the
assets constituting REMIC I to be treated for federal income tax purposes as a
REMIC. On the Startup Day, the REMIC I Regular Interests will be designated
"regular interests" in such REMIC and the Class R-I Certificate will be
designated the "residual interests" in such REMIC.

         The Trustee on behalf of the Trust shall make an election for the
assets constituting REMIC II to be treated for federal income tax purposes as a
REMIC. On the Startup Day, the REMIC II Regular Certificates will be designated
"regular interests" in such REMIC and the Class R-II Certificate will be
designated the "residual interests" in such REMIC.

         The Mortgage Loans will have an Outstanding Principal Balance as of the
Cut-off Date, after deducting all Scheduled Principal due on or before the
Cut-off Date, of approximately $270,274,998. The initial principal amount of the
Certificates will not exceed such Outstanding Principal Balance.

         In consideration of the mutual agreements herein contained, the Seller,
the Master Servicer, the Securities Administrator, EMC and the Trustee agree as
follows:

<PAGE>

                                   ARTICLE I

                                   Definitions

         Whenever used in this Agreement, the following words and phrases,
unless otherwise expressly provided or unless the context otherwise requires,
shall have the meanings specified in this Article.

         ACCEPTED MASTER SERVICING PRACTICES: With respect to any Mortgage Loan,
as applicable, either (x) those customary mortgage servicing practices of
prudent mortgage servicing institutions that master service mortgage loans of
the same type and quality as such Mortgage Loan in the jurisdiction where the
related Mortgaged Property is located, to the extent applicable to the Trustee
or the Master Servicer (except in its capacity as successor to a Servicer), or
(y) as provided in the applicable Servicing Agreement, to the extent applicable
to any Servicer, but in no event below the standard set forth in clause (x).

         ACCOUNT: The Master Servicer Collection Account and the Protected
Account as the context may require.

         ACCRUED CERTIFICATE INTEREST: For any Certificate for any Distribution
Date, the interest accrued during the related Interest Accrual Period at the
applicable Pass-Through Rate on the Current Principal Amount of such Certificate
immediately prior to such Distribution Date, calculated on the basis of a
360-day year consisting of twelve 30-day months, less (i) in the case of a
Senior Certificate, such Certificate's share of any Net Interest Shortfall and,
after the Cross-Over Date, the interest portion of any Realized Losses on the
Mortgage Loans allocated thereto in accordance with Section 6.02(g) and (ii) in
the case of a Subordinate Certificate, such Certificate's share of any Net
Interest Shortfall and the interest portion of any Realized Losses on the
Mortgage Loans allocated thereto in accordance with Section 6.02(g).

         AFFILIATE: As to any Person, any other Person controlling, controlled
by or under common control with such Person. "Control" means the power to direct
the management and policies of a Person, directly or indirectly, whether through
ownership of voting securities, by contract or otherwise. "Controlled" and
"Controlling" have meanings correlative to the foregoing. The Trustee may
conclusively presume that a Person is not an Affiliate of another Person unless
a Responsible Officer of the Trustee has actual knowledge to the contrary.

         AGREEMENT: This Pooling and Servicing Agreement and all amendments
hereof and supplements hereto.

         ALLOCABLE SHARE: With respect to each Class of Subordinate
Certificates:

         (a) as to any Distribution Date and amounts distributable pursuant to
clauses (i) and (iii) of the definition of Subordinate Optimal Principal Amount,
the fraction, expressed as a percentage, the numerator of which is the Current
Principal Amount of such Class and the denominator of which is the aggregate
Current Principal Amount of all Classes of the Subordinate Certificates; and

                                       -2-

<PAGE>

         (b) as to any Distribution Date and amounts distributable pursuant to
clauses (ii), (iv) and (v) of the definition of Subordinate Optimal Principal
Amount, and as to each Class of Subordinate Certificates (other than the Class
of Subordinate Certificates having the lowest numerical designation as to which
the Class Prepayment Distribution Trigger shall not be applicable) for which (x)
the related Class Prepayment Distribution Trigger has been satisfied on such
Distribution Date, the fraction, expressed as a percentage, the numerator of
which is the Current Principal Amount of such Class and the denominator of which
is the aggregate Current Principal Amount of all such Classes of Subordinate
Certificates and (y) the related Class Prepayment Distribution Trigger has not
been satisfied on such Distribution Date, 0%; provided that if on a Distribution
Date, the Current Principal Amount of any Class of Subordinate Certificates for
which the related Class Prepayment Distribution Trigger was satisfied on such
Distribution Date is reduced to zero, any amounts distributed pursuant to this
clause (b), to the extent of such Class's remaining Allocable Share, shall be
distributed to the remaining Classes of Subordinate Certificates which satisfy
the related Class Prepayment Distribution Trigger and to the Class of
Subordinate Certificates having the lowest numerical designation in reduction of
their respective Current Principal Amounts in the order of their numerical Class
designations.

         APPLICABLE CREDIT RATING: For any long-term deposit or security, a
credit rating of AAA in the case of S&P or Aaa in the case of Moody's. For any
short-term deposit or security, or a rating of A-l+ in the case of S&P or P-1 in
the case of Moody's.

State Law shall be (a) the law of the State of New York and (b) such other state
law whose applicability shall have been brought to the attention of the
Securities Administrator and the Trustee by either (i) an Opinion of Counsel
reasonably acceptable to the Securities Administrator and the Trustee delivered
to it by the Master Servicer or the Seller, or (ii) written notice from the
appropriate taxing authority as to the applicability of such state law.

         APPRAISED VALUE: For any Mortgaged Property related to a Mortgage Loan,
the amount set forth as the appraised value of such Mortgaged Property in an
appraisal made for the mortgage originator in connection with its origination of
the related Mortgage Loan.

         ASSIGNMENT AGREEMENTS: The agreements attached hereto as Exhibit I,
whereby the Servicing Agreements were assigned to the Trustee for the benefit of
the Certificateholders

         ASSUMED FINAL DISTRIBUTION DATE: April 25, 2032, or if such day is not
a Business Day, the next succeeding Business Day.

Group 1 and Group 2 Available Funds for such Distribution Date.

         AVERAGE LOSS SEVERITY: With respect to any period and each Loan Group,

                          Conveyance of Mortgage Loans;
                        Original Issuance of Certificates

         Section 2.01 CONVEYANCE OF MORTGAGE LOANS TO TRUSTEE. (a) The Seller
concurrently with the execution and delivery of this Agreement, sells, transfers
and assigns to the Trust without recourse all its right, title and interest in
and to (i) the Mortgage Loans identified in the Mortgage Loan Schedule,
including all interest and principal due with respect to the Mortgage Loans
after the Cut-off Date, but excluding any payments of principal and interest due
on or prior to the Cut-off Date; (ii) such assets as shall from time to time be
credited or are required by the terms of this Agreement to be credited to the

foregoing. Although it is the intent of the parties to this Agreement that the
conveyance of the Seller's right, title and interest in and to the Mortgage
Loans and other assets in the Trust Fund pursuant to this Agreement shall
constitute a purchase and sale and not a loan, in the event that such conveyance
is deemed to be a loan, it is the intent of the parties to this Agreement that
the Seller shall be deemed to have granted to the Trustee a first priority
perfected security interest in all of the Seller's right, title and interest in,
to and under the Mortgage Loans and other assets in the Trust Fund, and that
this Agreement shall constitute a security agreement under applicable law.

         (b) In connection with the above transfer and assignment, the Seller
hereby deposits with the Trustee or the Custodian, as its agent, with respect to
each Mortgage Loan, (i) the original Mortgage Note, endorsed without recourse to
the order of the Trustee and showing an unbroken chain of endorsements from the
original payee thereof to the Person endorsing it to the Trustee, or lost note
affidavit, (ii) the original Security Instrument, which shall have been

copy of the assignment (which may be in the form of a blanket assignment if
permitted in the jurisdiction in which the Mortgaged Property is located) to
"Bank One, National Association, as Trustee", with evidence of recording with
respect to each Mortgage Loan in the name of the Trustee thereon (or if clause
(x) in the proviso below applies or for Mortgage Loans with respect to which the
related Mortgaged Property is located in a state other than Maryland or an
Opinion of Counsel has been provided as set forth in this Section 2.01(b), shall
be in recordable form), (iv) all intervening assignments of the Security
Instrument, if applicable and only to the extent available to the Seller with
evidence of recording thereon, (v) the original or a copy of the policy or
certificate of primary mortgage guaranty insurance, to the extent available, if
any, (vi) the original policy of title insurance or mortgagee's certificate of
title insurance or commitment or binder for title insurance and (vii) originals
of all modification agreements, if applicable and available;

PROVIDED, HOWEVER, that in lieu of the foregoing, the Seller may deliver the
following documents, under the circumstances set forth below: (x) in lieu of the
original Security Instrument, assignments to the Trustee or intervening
assignments thereof which have been delivered, are being delivered or will, upon
receipt of recording information relating to the Security Instrument required to
be included thereon, be delivered to recording offices for recording and have
not been returned to the Seller in time to permit their delivery as specified
above, the Seller may deliver a true copy thereof with a certification by the
Seller, on the face of such copy, substantially as follows: "Certified to be a
true and correct copy of the original, which has been transmitted for
recording"; (y) in lieu of the Security Instrument, assignment to the Trustee or
intervening assignments thereof, if the applicable jurisdiction retains the
originals of such documents (as evidenced by a certification from the Seller to
such effect) the Seller may deliver photocopies of such documents containing an
original certification by the judicial or other governmental authority of the
jurisdiction where such documents were recorded; and (z) the Seller shall not be
required to deliver intervening assignments or Mortgage Note endorsements
between the related Underlying Seller and EMC Mortgage Corporation, between EMC
Mortgage Corporation and the Depositor, and between the Depositor and the
Trustee; and provided, further, however, that in the case of Mortgage Loans
which have been prepaid in full after the Cut-off Date and prior to the Closing
Date, the Seller, in lieu of delivering the above documents, may deliver to the
Trustee or the Custodian, as its agent, a certification to such effect and shall
deposit all amounts paid in respect of such Mortgage Loans in the Master
Servicer Collection Account on the Closing Date. The Seller shall deliver such
original documents (including any original documents as to which certified
copies had previously been delivered) to the Trustee or the Custodian, as its
agent, promptly after they are received. The Seller shall cause, at its expense,
the assignment of the Security Instrument to the Trustee to be recorded not
later than 180 days after the Closing Date, unless such recordation is not
required by the Rating Agencies or an Opinion of Counsel has been provided to
the Trustee (with a copy to the Custodian) which states that recordation of such
Security Instrument is not required to protect the interests of the
Certificateholders in the related Mortgage Loans; provided, however, that each
assignment shall be submitted for recording by the Seller in the manner
described above, at no expense to the Trust or the Trustee or the Custodian, as
its agent, upon the earliest to occur of : (i) reasonable direction by the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 25% of the Trust, (ii) the occurrence of an Event of Default,
(iii) the occurrence of a bankruptcy, insolvency or foreclosure relating to the
Seller and (iv) the occurrence of a servicing transfer as described in Section
8.02 hereof. Notwithstanding the foregoing, if the Seller fails to pay the cost
of recording the assignments, such expense will be paid by the Trustee and the
Trustee shall be reimbursed for such expenses by the Trust in accordance with
Section 9.05.

         Section 2.02 ACCEPTANCE OF MORTGAGE LOANS BY TRUSTEE. (a) The Trustee
acknowledges the sale, transfer and assignment of the Trust to it by the Seller
and receipt of, subject to further review and the exceptions which may be noted
pursuant to the procedures described below, and declares that it holds, the
documents (or certified copies thereof) delivered to it pursuant to Section
2.01, and declares that it will continue to hold those documents and any
amendments, replacements or supplements thereto and all other assets of the
Trust Fund delivered to it as Trustee in trust for the use and benefit of all
present and future Holders of the Certificates. On the Closing Date, the
Custodian, with respect to the Mortgage Loans, shall acknowledge with respect to
each Mortgage Loan by an Initial Certification substantially in the form of
Exhibit One to the Custodial Agreement receipt of the Mortgage File, but without
review of such Mortgage File, except to the extent

                                      -28-

<PAGE>

necessary to confirm that such Mortgage File contains the related Mortgage Note
or lost note affidavit. No later than 90 days after the Closing Date (or, with
respect to any Substitute Mortgage Loan, within five Business Days after the
receipt by the Trustee or Custodian thereof), the Trustee agrees, for the
benefit of the Certificateholders, to review or cause to be reviewed by the
Custodian on its behalf (under the Custodial Agreement), each Mortgage File
delivered to it and to execute and deliver, or cause to be executed and
delivered, to the Seller and the Master Servicer an Interim Certification
substantially in the form annexed as Exhibit Two to the Custodial Agreement. In
conducting such review, the Trustee or Custodian will ascertain whether all
required documents have been executed and received, and based on the Mortgage
Loan Schedule, whether those documents relate, determined on the basis of the
Mortgagor name, original principal balance and loan number, to the Mortgage
Loans it has received, as identified in the Mortgage Loan Schedule. In
performing any such review, the Trustee or the Custodian, as its agent, may
conclusively rely on the purported due execution and genuineness of any such
document and on the purported genuineness of any signature thereon. If the
Trustee or the Custodian, as its agent, finds any document constituting part of
the Mortgage File not to have been executed or received, or to be unrelated to
the Mortgage Loans identified in Exhibit B or to appear to be defective on its
face, the Trustee or the Custodian, as its agent, shall promptly notify the
Mortgage Loan Seller. In accordance with the Mortgage Loan Purchase Agreement,
the Mortgage Loan Seller shall correct or cure any such defect within ninety
(90) days from the date of notice from the Trustee or the Custodian, as its
agent, of the defect and if the Mortgage Loan Seller fails to correct or cure
the defect within such period, and such defect materially and adversely affects
the interests of the Certificateholders in the related Mortgage Loan, the
Trustee or the Custodian, as its agent, shall enforce the Mortgage Loan Seller's
obligation pursuant to the Mortgage Loan Purchase Agreement, within 90 days from
the Trustee's or the Custodian's notification, to purchase such Mortgage Loan at
the Repurchase Price; provided that, if such defect would cause the Mortgage
Loan to be other than a "qualified mortgage" as defined in Section 860G(a)(3) of
the Code, any such cure or repurchase must occur within 90 days from the date
such breach was discovered; provided, however, that if such defect relates
solely to the inability of the Mortgage Loan Seller to deliver the original
Security Instrument or intervening assignments thereof, or a certified copy
because the originals of such documents, or a certified copy have not been
returned by the applicable jurisdiction, the Mortgage Loan Seller shall not be
required to purchase such Mortgage Loan if the Mortgage Loan Seller delivers
such original documents or certified copy promptly upon receipt, but in no event
later than 360 days after the Closing Date. The foregoing repurchase obligation
shall not apply in the event that the Mortgage Loan Seller cannot deliver such
original or copy of any document submitted for recording to the appropriate
recording office in the applicable jurisdiction because such document has not
been returned by such office; provided that the Mortgage Loan Seller shall
instead deliver a recording receipt of such recording office or, if such receipt
is not available, a certificate confirming that such documents have been
accepted for recording, and delivery to the Trustee or the Custodian, as its
agent, shall be effected by the Mortgage Loan Seller within thirty days of its
receipt of the original recorded document.

         (b) No later than 180 days after the Closing Date, the Trustee or the
Custodian, as its agent, will review, for the benefit of the Certificateholders,
the Mortgage Files delivered to it and will execute and deliver or cause to be
executed and delivered to the Seller a Final Certification substantially in the
form annexed as Exhibit Three to the Custodial Agreement. In conducting such
review, the Trustee or the Custodian, as its agent, will ascertain whether an
original of each document required to be recorded has been returned from the
recording office with evidence of

                                      -29-

<PAGE>

recording thereon or a certified copy has been obtained from the recording
office. If the Trustee or the Custodian, as its agent, finds any document
constituting part of the Mortgage File has not been received, or to be
unrelated, determined on the basis of the Mortgagor name, original principal
balance and loan number, to the Mortgage Loans identified in Exhibit B or to
appear defective on its face, the Trustee or the Custodian, as its agent, shall
promptly notify the Mortgage Loan Seller (provided, however, that with respect
to those documents described in subsection (b)(iv), (b)(v) and (b)(vii) of
Section 2.01, the Trustee's obligations shall extend only to the documents
actually delivered pursuant to such subsections). In accordance with the
Mortgage Loan Purchase Agreement, the Mortgage Loan Seller shall correct or cure
any such defect or EMC shall deliver to the Trustee an Opinion of Counsel to the
effect that such defect does not materially or adversely affect the interests of
Certificateholders in such Mortgage Loan within 90 days from the date of notice
from the Trustee of the defect and if the Mortgage Loan Seller is unable to cure
such defect within such period, and if such defect materially and adversely
affects the interests of the Certificateholders in the related Mortgage Loan,
the Trustee shall enforce the Mortgage Loan Seller's obligation under the
Mortgage Loan Purchase Agreement to purchase such Mortgage Loan at the
Repurchase Price, provided, however, that if such defect relates solely to the
inability of the Mortgage Loan Seller to deliver the original Security
Instrument or intervening assignments thereof, or a certified copy, because the
originals of such documents. or a certified copy, have not been returned by the
applicable jurisdiction, the Mortgage Loan Seller shall not be required to
purchase such Mortgage Loan, if the Mortgage Loan Seller delivers such original
documents or certified copy promptly upon receipt, but in no event later than
360 days after the Closing Date.

         (c) In the event that a Mortgage Loan is purchased by the Mortgage Loan
Seller in accordance with Subsections 2.02(a) or (b) above, the Mortgage Loan
Seller shall remit to the Master Servicer the Repurchase Price for deposit in
the Master Servicer Collection Account and the Mortgage Loan Seller shall
provide to the Trustee written notification detailing the components of the
Repurchase Price. Upon deposit of the Repurchase Price in the Master Servicer
Collection Account, the Seller shall notify the Trustee and the Trustee or the
Custodian, as its agent (upon receipt of a Request for Release in the form of
Exhibit D attached hereto with respect to such Mortgage Loan), shall release to
the Mortgage Loan Seller the related Mortgage File and the Trustee shall execute
and deliver all instruments of transfer or assignment, without recourse,
furnished to it by the Mortgage Loan Seller as are necessary to vest in the
Mortgage Loan Seller title to and rights under the Mortgage Loan. Such purchase
shall be deemed to have occurred on the date on which the Repurchase Price in
available funds is received by the Trustee. The Trustee shall amend the Mortgage
Loan Schedule, which was previously delivered to it by Seller in a form agreed
to between the Seller and the Trustee, to reflect such repurchase and shall
promptly notify the Rating Agencies and the Master Servicer of such amendment.
The obligation of the Mortgage Loan Seller to repurchase any Mortgage Loan as to
which such a defect in a constituent document exists shall be the sole remedy
respecting such defect available to the Certificateholders or to the Trustee on
their behalf.

         Section 2.03 ASSIGNMENT OF INTEREST IN THE MORTGAGE LOAN PURCHASE
AGREEMENT. (a) The Seller hereby assigns to the Trustee, on behalf of the
Certificateholders, all of its right, title and interest in the Mortgage Loan
Purchase Agreement, including but not limited to Seller's rights and obligations
pursuant to the Servicing Agreements (noting that the Mortgage Loan Seller has
retained the right in the event of breach of the representations, warranties and
covenants, if any, with respect to the related Mortgage Loans of the related
Servicer under the related Servicing Agreement to enforce the provisions thereof
and to seek all or any available remedies). The obligations of the Mortgage Loan
Seller to substitute or repurchase, as applicable, a Mortgage Loan shall be the
Trustee's and the Certificateholders' sole remedy for any breach thereof. At the
request of the Trustee, the Seller shall take such actions as may be necessary
to enforce the above right, title and interest on behalf of the Trustee and the
Certificateholders or shall execute such further documents as the Trustee may
reasonably require in order to enable the Trustee to carry out such enforcement.

         (b) If the Seller, the Securities Administrator or the Trustee
discovers a breach of any of the representations and warranties set forth in the
Mortgage Loan Purchase Agreement, which breach materially and adversely affects
the value of the interests of Certificateholders or the Trustee in the related
Mortgage Loan, the party discovering the breach shall give prompt written notice
of the breach to the other parties. The Mortgage Loan Seller, within 90 days of
its discovery or receipt of notice that such breach has occurred (whichever
occurs earlier), shall cure the breach in all material respects or, subject to
the Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as
applicable, shall purchase the Mortgage Loan or any property acquired with
respect thereto from the Trustee; provided, however, that if there is a breach
of any representation set forth in the Mortgage Loan Purchase Agreement or
Section 2.04 of this Agreement, as applicable, and the Mortgage Loan or the
related property acquired with respect thereto has been sold, then the Mortgage
Loan Seller shall pay, in lieu of the Repurchase Price, any excess of the
Repurchase Price over the Net Liquidation Proceeds received upon such sale. (If
the Net Liquidation Proceeds exceed the Repurchase Price, any excess shall be
paid to the Mortgage Loan Seller to the extent not required by law to be paid to
the borrower.) Any such purchase by the Mortgage Loan Seller shall be made by
providing an amount equal to the Repurchase Price to the Master Servicer for
deposit in the Master Servicer Collection Account and written notification
detailing the components of such Repurchase Price. The Seller shall notify the
Trustee and submit to the Trustee or the Custodian, as its agent, a Request for
Release in the form of Exhibit D attached hereto, and the Trustee shall release,
or the Trustee shall cause the Custodian to release, to the Mortgage Loan Seller
the related Mortgage File and the Trustee shall execute and deliver all
instruments of transfer or assignment furnished to it by the Mortgage Loan
Seller, without recourse, as are necessary to vest in the Mortgage Loan Seller
title to and rights under the Mortgage Loan or any property acquired with
respect thereto. Such purchase shall be deemed to have occurred on the date on
which the Repurchase Price in available funds is received by the Trustee. The
Trustee shall amend the Mortgage Loan Schedule to reflect such repurchase and
shall promptly notify the Master Servicer and the Rating Agencies of such
amendment. Enforcement of the obligation of the Mortgage Loan Seller to purchase
(or substitute a Substitute Mortgage Loan for) any Mortgage Loan or any property
acquired with respect thereto (or pay the Repurchase Price as set forth in the
above proviso) as to which a breach has occurred and is continuing shall
constitute the sole remedy respecting such breach available to the
Certificateholders or the Trustee on their behalf.

         Section 2.04 SUBSTITUTION OF MORTGAGE LOANS. Notwithstanding anything
to the contrary in this Agreement, in lieu of purchasing a Mortgage Loan
pursuant to the Mortgage Loan Purchase Agreement or Sections 2.02 or 2.03 of
this Agreement, the Mortgage Loan Seller may, no later than the date by which
such purchase by the Mortgage Loan Seller would otherwise be required, tender to
the Trustee a Substitute Mortgage Loan accompanied by a certificate of an
authorized officer of the Mortgage Loan Seller that such Substitute Mortgage
Loan conforms to the requirements set forth in the definition of "Substitute
Mortgage Loan" in the Mortgage Loan Purchase Agreement or this Agreement, as
applicable; provided, however, that substitution pursuant to the Mortgage Loan
Purchase Agreement or Section 2.04 of this Agreement, as applicable, in lieu of
purchase shall not be permitted after the termination of the two-year period
beginning on the Startup Day; provided, further, that if the breach would cause
the Mortgage Loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Code, any such cure or substitution must occur within 90 days
from the date the breach was discovered. The Trustee or the Custodian, as its
agent, shall examine the Mortgage File for any Substitute Mortgage Loan in the
manner set forth in Section 2.02(a) and the Trustee or the Custodian, as its
agent, shall notify the Mortgage Loan Seller, in writing, within five Business
Days after receipt, whether or not the documents relating to the Substitute
Mortgage Loan satisfy the requirements of the fourth sentence of Subsection
2.02(a). Within two Business Days after such notification, the Mortgage Loan
Seller shall provide to the Trustee for deposit in the Distribution Account the
amount, if any, by which the Outstanding Principal Balance as of the next
preceding Due Date of the Mortgage Loan for which substitution is being made,
after giving effect to Scheduled Principal due on such date, exceeds the
Outstanding Principal Balance as of such date of the Substitute Mortgage Loan,
after giving effect to Scheduled Principal due on such date, which amount shall
be treated for the purposes of this Agreement as if it were the payment by the
Mortgage Loan Seller of the Repurchase Price for the purchase of a Mortgage Loan
by the Mortgage Loan Seller. After such notification to the Mortgage Loan Seller
and, if any such excess exists, upon receipt of such deposit, the Trustee shall
accept such Substitute Mortgage Loan which shall thereafter be deemed to be a
Mortgage Loan hereunder. In the event of such a substitution, accrued interest
on the Substitute Mortgage Loan for the month in which the substitution occurs
and any Principal Prepayments made thereon during such month shall be the
property of the Trust Fund and accrued interest for such month on the Mortgage
Loan for which the substitution is made and any Principal Prepayments made
thereon during such month shall be the property of the Mortgage Loan Seller. The
Scheduled Principal on a Substitute Mortgage Loan due on the Due Date in the
month of substitution shall be the property of the Mortgage Loan Seller and the
Scheduled Principal on the Mortgage Loan for which the substitution is made due
on such Due Date shall be the property of the Trust Fund. Upon acceptance of the
Substitute Mortgage Loan (and delivery to the Trustee or Custodian of a Request
for Release for such Mortgage Loan), the Trustee shall release to the Mortgage
Loan Seller the related Mortgage File related to any Mortgage Loan released
pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of this
Agreement, as applicable, and shall execute and deliver all instruments of
transfer or assignment, without recourse, in form as provided to it as are
necessary to vest in the Mortgage Loan Seller title to and rights under any
Mortgage Loan released pursuant to the Mortgage Loan Purchase Agreement or
Section 2.04 of this Agreement, as applicable. The Mortgage Loan Seller shall
deliver the documents related to the Substitute Mortgage Loan in accordance with
the provisions of the Mortgage Loan Purchase Agreement or Subsections 2.01(b)
and 2.02(b) of this Agreement, as applicable, with the date of acceptance of the
Substitute Mortgage Loan deemed to be the Closing Date for purposes of the time
periods set forth in those Subsections. The representations and warranties set
forth in the Mortgage

                                      -32-

<PAGE>

Loan Purchase Agreement shall be deemed to have been made by the Mortgage Loan
Seller with respect to each Substitute Mortgage Loan as of the date of
acceptance of such Mortgage Loan by the Trustee. The Master Servicer shall amend
the Mortgage Loan Schedule to reflect such substitution and shall provide a copy
of such amended Mortgage Loan Schedule to the Trustee and the Rating Agencies.

        Section 2.05 ISSUANCE OF CERTIFICATES. The Trustee acknowledges the
assignment to it of the Mortgage Loans and the other assets comprising the Trust
Fund and, concurrently therewith, has signed, and countersigned and delivered to
the Seller, in exchange therefor, Certificates in such authorized denominations
representing such Fractional Undivided Interests as the Seller has requested.
The Trustee agrees that it will hold the Mortgage Loans and such other assets as
may from time to time be delivered to it segregated on the books of the Trustee
in trust for the benefit of the Certificateholders.

        The Seller, concurrently with the execution and delivery hereof, does
hereby transfer, assign, set over and otherwise convey in trust to the Trustee
without recourse all the right, title and interest of the Seller in and to the
REMIC I Regular Interests and the other assets of REMIC II for the benefit of
the holders of the REMIC II Certificates. The Trustee acknowledges receipt of
the REMIC I Regular Interests (which are uncertificated) and the other assets of
REMIC II and declares that it holds and will hold the same in trust for the
exclusive use and benefit of the holders of the REMIC II Certificates.

        Section 2.06 REPRESENTATIONS AND WARRANTIES CONCERNING THE SELLER. The
Seller hereby represents and warrants to the Trustee, the Master Servicer and
the Securities Administrator as follows:

               (i) the Seller (a) is a corporation duly organized, validly
        existing and in good standing under the laws of the State of Delaware
        and (b) is qualified and in good standing as a foreign corporation to do
        business in each jurisdiction where such qualification is necessary,
        except where the failure so to qualify would not reasonably be expected
        to have a material adverse effect on the Seller's business as presently
        conducted or on the Seller's ability to enter into this Agreement and to
        consummate the transactions contemplated hereby;

               (ii) the Seller has full corporate power to own its property, to
        carry on its business as presently conducted and to enter into and
        perform its obligations under this Agreement;

               (iii) the execution and delivery by the Seller of this Agreement
        have been duly authorized by all necessary corporate action on the part
        of the Seller; and neither the execution and delivery of this Agreement,
        nor the consummation of the transactions herein contemplated, nor
        compliance with the provisions hereof, will conflict with or result in a
        breach of, or constitute a default under, any of the provisions of any
        law, governmental rule, regulation, judgment, decree or order binding on
        the Seller or its properties or the articles of incorporation or by-laws
        of the Seller, except those conflicts, breaches or defaults which would
        not reasonably be expected to have a material adverse effect on the
        Seller's ability to enter into this Agreement and to consummate the
        transactions contemplated hereby;

                                      -33-

<PAGE>

               (iv) the execution, delivery and performance by the Seller of
        this Agreement and the consummation of the transactions contemplated
        hereby do not require the consent or approval of, the giving of notice
        to, the registration with, or the taking of any other action in respect
        of, any state, federal or other governmental authority or agency, except
        those consents, approvals, notices, registrations or other actions as
        have already been obtained, given or made;

               (v) this Agreement has been duly executed and delivered by the
        Seller and, assuming due authorization, execution and delivery by the
        other parties hereto, constitutes a valid and binding obligation of the
        Seller enforceable against it in accordance with its terms (subject to
        applicable bankruptcy and insolvency laws and other similar laws
        affecting the enforcement of the rights of creditors generally);

               (vi) there are no actions, suits or proceedings pending or, to
        the knowledge of the Seller, threatened against the Seller, before or by
        any court, administrative agency, arbitrator or governmental body (i)
        with respect to any of the transactions contemplated by this Agreement
        or (ii) with respect to any other matter which in the judgment of the
        Seller will be determined adversely to the Seller and will if determined
        adversely to the Seller materially and adversely affect the Seller's
        ability to enter into this Agreement or perform its obligations under
        this Agreement; and the Seller is not in default with respect to any
        order of any court, administrative agency, arbitrator or governmental
        body so as to materially and adversely affect the transactions
        contemplated by this Agreement; and

               (vii) immediately prior to the transfer and assignment to the
        Trustee, each Mortgage Note and each Mortgage were not subject to an
        assignment or pledge, and the Seller had good and marketable title to
        and was the sole owner thereof and had full right to transfer and sell
        such Mortgage Loan to the Trustee free and clear of any encumbrance,
        equity, lien, pledge, charge, claim or security interest.

                                   ARTICLE III

                 Administration and Servicing of Mortgage Loans

        Section 3.01 MASTER SERVICER. The Master Servicer shall supervise,
monitor and oversee the obligation of the Servicers to service and administer
their respective Mortgage Loans in accordance with the terms of the applicable
Servicing Agreement and shall have full power and authority to do any and all
things which it may deem necessary or desirable in connection with such master
servicing and administration. In performing its obligations hereunder, the
Master Servicer shall act in a manner consistent with Accepted Master Servicing
Practices. Furthermore, the Master Servicer shall oversee and consult with each
Servicer as necessary from time-to-time to carry out the Master Servicer's
obligations hereunder, shall receive, review and evaluate all reports,
information and other data provided to the Master Servicer by each Servicer and
shall cause each Servicer to perform and observe the covenants, obligations and
conditions to be performed or observed by such Servicer under the applicable
Servicing Agreement. The Master Servicer shall independently and separately
monitor each Servicer's servicing activities with respect to each related
Mortgage Loan, reconcile the results of such monitoring with such information
provided in the previous sentence on a monthly basis and coordinate corrective
adjustments to the Servicers' and Master Servicer's records, and based on such
reconciled and corrected information, the Master Servicer shall provide such
information to the Securities Administrator as shall be necessary in order for
it to prepare the statements specified in Section 6.04, and prepare any other
information and statements required to be forwarded by the Master Servicer
hereunder. The Master Servicer shall reconcile the results of its Mortgage Loan
monitoring with the actual remittances of the Servicers to the Protected Account
pursuant to the applicable Servicing Agreements.

        The Trustee shall furnish the Servicers and the Master Servicer with any
powers of attorney and other documents in form as provided to it necessary or
appropriate to enable the Servicers and the Master Servicer to service and
administer the related Mortgage Loans and REO Property.

        The Trustee shall provide access to the records and documentation in
possession of the Trustee regarding the related Mortgage Loans and REO Property
and the servicing thereof to the Certificateholders, the FDIC, and the
supervisory agents and examiners of the FDIC, such access being afforded only
upon reasonable prior written request and during normal business hours at the
office of the Trustee; provided, however, that, unless otherwise required by
law, the Trustee shall not be required to provide access to such records and
documentation if the provision thereof would violate the legal right to privacy
of any Mortgagor. The Trustee shall allow representatives of the above entities
to photocopy any of the records and documentation and shall provide equipment
for that purpose at a charge that covers the Trustee's actual costs.

        The Trustee shall execute and deliver to the related Servicer and the
Master Servicer any court pleadings, requests for trustee's sale or other
documents necessary or desirable to (i) the foreclosure or trustee's sale with
respect to a Mortgaged Property; (ii) any legal action brought to obtain
judgment against any Mortgagor on the Mortgage Note or Security Instrument;
(iii) obtain a deficiency judgment against the Mortgagor; or (iv) enforce any
other rights or remedies provided by the Mortgage Note or Security Instrument or
otherwise available at law or equity.

        Section 3.02 REMIC-RELATED COVENANTS. For as long as each REMIC shall
exist, the Trustee and the Securities Administrator shall act in accordance
herewith to assure continuing treatment of such REMIC as a REMIC, and the
Trustee and the Securities Administrator shall comply with any directions of the
Seller, the related Servicer or the Master Servicer to assure such continuing
treatment. In particular, the Trustee shall not (a) sell or permit the sale of
all or any portion of the Mortgage Loans or of any investment of deposits in an
Account unless such sale is as a result of a repurchase of the Mortgage Loans
pursuant to this Agreement or the Trustee has received a REMIC Opinion prepared
at the expense of the Trust Fund; and (b) other than with respect to a
substitution pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of
this Agreement, as applicable, accept any contribution to any REMIC after the
Startup Day without receipt of a REMIC Opinion.

        Section 3.03 MONITORING OF SERVICERS. (a) The Master Servicer shall be
responsible for reporting to the Trustee and the Seller the compliance by each
Servicer with its duties under the related Servicing Agreement. In the review of
each Servicer's activities, the Master Servicer may rely upon an officer's
certificate of the Servicer with regard to such Servicer's compliance with the
terms of its Servicing Agreement. In the event that the Master Servicer, in its
judgment, determines that a Servicer should be terminated in accordance with its
Servicing Agreement, or that a notice should be sent pursuant to such Servicing
Agreement with respect to the occurrence of an event that, unless cured, would
constitute grounds for such termination, the Master Servicer shall notify the
Seller and the Trustee thereof and the Master Servicer shall issue such notice
or take such other action as it deems appropriate.

        (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of each Servicer under the
related Servicing Agreement, and shall, in the event that a Servicer fails to
perform its obligations in accordance with the related Servicing Agreement,
subject to the preceding paragraph, terminate the rights and obligations of such
Servicer thereunder and act as servicer of the related Mortgage Loans or to
cause the Trustee to enter in to a new Servicing Agreement with a successor
Servicer selected by the Master Servicer; provided, however, it is understood
and acknowledged by the parties hereto that there will be a period of transition
(not to exceed 90 days) before the actual servicing functions can be fully
transferred to such successor Servicer. Such enforcement, including, without
limitation, the legal prosecution of claims, termination of Servicing Agreements
and the pursuit of other appropriate remedies, shall be in such form and carried
out to such an extent and at such time as the Master Servicer, in its good faith
business judgment, would require were it the owner of the related Mortgage
Loans. The Master Servicer shall pay the costs of such enforcement at its own
expense, provided that the Master Servicer shall not be required to prosecute or
defend any legal action except to the extent that the Master Servicer shall have
received reasonable indemnity for its costs and expenses in pursuing such
action.

        (c) To the extent that the costs and expenses of the Master Servicer
related to any termination of a Servicer, appointment of a successor Servicer or
the transfer and assumption of servicing by the Master Servicer with respect to
any Servicing Agreement (including, without limitation, (i) all legal costs and
expenses and all due diligence costs and expenses associated with an evaluation
of the potential termination of the Servicer as a result of an event of default
by such Servicer and (ii) all costs and expenses associated with the complete
transfer of servicing, including

                                      -36-

<PAGE>

all servicing files and all servicing data and the completion, correction or
manipulation of such servicing data as may be required by the successor servicer
to correct any errors or insufficiencies in the servicing data or otherwise to
enable the successor service to service the Mortgage Loans in accordance with
the related Servicing Agreement) are not fully and timely reimbursed by the
terminated Servicer, the Master Servicer shall be entitled to reimbursement of
such costs and expenses from the Master Servicer Collection Account.

        (d) The Master Servicer shall require each Servicer to comply with the
remittance requirements and other obligations set forth in the related Servicing
Agreement.

        (e) If the Master Servicer acts as Servicer, it will not assume
liability for the representations and warranties of the Servicer, if any, that
it replaces.

        Section 3.04 FIDELITY BOND. The Master Servicer, at its expense, shall
maintain in effect a blanket fidelity bond and an errors and omissions insurance
policy, affording coverage with respect to all directors, officers, employees
and other Persons acting on such Master Servicer's behalf, and covering errors
and omissions in the performance of the Master Servicer's obligations hereunder.
The errors and omissions insurance policy and the fidelity bond shall be in such
form and amount generally acceptable for entities serving as master servicers or
trustees.

        Section 3.05 POWER TO ACT; PROCEDURES. The Master Servicer shall master
service the Mortgage Loans and shall have full power and authority, subject to
the REMIC Provisions and the provisions of Article X hereof, to do any and all
things that it may deem necessary or desirable in connection with the master
servicing and administration of the Mortgage Loans, including but not limited to
the power and authority (i) to execute and deliver, on behalf of the
Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents, (ii) to consent to transfers of any Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to
collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate
foreclosure or other conversion of the ownership of the Mortgaged Property
securing any Mortgage Loan, in each case, in accordance with the provisions of
this Agreement and the related Servicing Agreement, as applicable; provided,
however, that the Master Servicer shall not (and, consistent with its
responsibilities under Section 3.03, shall not permit any Servicer to) knowingly
or intentionally take any action, or fail to take (or fail to cause to be taken)
any action reasonably within its control and the scope of duties more
specifically set forth herein, that, under the REMIC Provisions, if taken or not
taken, as the case may be, would cause REMIC I or REMIC II to fail to qualify as
a REMIC or result in the imposition of a tax upon the Trust Fund (including but
not limited to the tax on prohibited transactions as defined in Section
860F(a)(2) of the Code and the tax on contributions to a REMIC set forth in
Section 860G(d) of the Code) unless the Master Servicer has received an Opinion
of Counsel (but not at the expense of the Master Servicer) to the effect that
the contemplated action will not would cause REMIC I or REMIC II to fail to
qualify as a REMIC or result in the imposition of a tax upon REMIC I or REMIC
II, as the case may be. The Trustee shall furnish the Master Servicer, upon
written request from a Servicing Officer, with any powers of attorney empowering
the Master Servicer or any Servicer to execute and deliver instruments of
satisfaction or cancellation, or of partial or full release or discharge, and to
foreclose upon or otherwise liquidate Mortgaged Property, and to appeal,
prosecute or defend in any court action relating to the Mortgage Loans or the
Mortgaged Property, in accordance with the applicable Servicing Agreement and
this

                                      -37-

<PAGE>

Agreement, and the Trustee shall execute and deliver such other documents, as
the Master Servicer may request, to enable the Master Servicer to master service
and administer the Mortgage Loans and carry out its duties hereunder, in each
case in accordance with Accepted Master Servicing Practices (and the Trustee
shall have no liability for misuse of any such powers of attorney by the Master
Servicer or any Servicer). If the Master Servicer or the Trustee has been
advised that it is likely that the laws of the state in which action is to be
taken prohibit such action if taken in the name of the Trustee or that the
Trustee would be adversely affected under the "doing business" or tax laws of
such state if such action is taken in its name, the Master Servicer shall join
with the Trustee in the appointment of a co-trustee pursuant to Section 9.11
hereof. In the performance of its duties hereunder, the Master Servicer shall be
an independent contractor and shall not, except in those instances where it is
taking action in the name of the Trustee, be deemed to be the agent of the
Trustee.

        Section 3.06 DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS. To the extent
provided in the applicable Servicing Agreement, to the extent Mortgage Loans
contain enforceable due-on-sale clauses, the Master Servicer shall cause the
Servicers to enforce such clauses in accordance with the applicable Servicing
Agreement. If applicable law prohibits the enforcement of a due-on-sale clause
or such clause is otherwise not enforced in accordance with the applicable
Servicing Agreement, and, as a consequence, a Mortgage Loan is assumed, the
original Mortgagor may be released from liability in accordance with the
applicable Servicing Agreement.

        Section 3.07 RELEASE OF MORTGAGE FILES. (a) Upon becoming aware of the
payment in full of any Mortgage Loan, or the receipt by any Servicer of a
notification that payment in full has been escrowed in a manner customary for
such purposes for payment to Certificateholders on the next Distribution Date,
the Servicer will, if required under the applicable Servicing Agreement,
promptly furnish to the Custodian, on behalf of the Trustee, two copies of a
certification substantially in the form of Exhibit D hereto signed by a
Servicing Officer or in a mutually agreeable electronic format which will, in
lieu of a signature on its face, originate from a Servicing Officer (which
certification shall include a statement to the effect that all amounts received
in connection with such payment that are required to be deposited in the
Protected Account maintained by the applicable Servicer pursuant to Section 4.01
or by the applicable Servicer pursuant to its Servicing Agreement have been or
will be so deposited) and shall request that the Custodian, on behalf of the
Trustee, deliver to the applicable Servicer the related Mortgage File. Upon
receipt of such certification and request, the Custodian, on behalf of the
Trustee, shall promptly release the related Mortgage File to the applicable
Servicer and the Trustee and Custodian shall have no further responsibility with
regard to such Mortgage File. Upon any such payment in full, each Servicer is
authorized, to give, as agent for the Trustee, as the mortgagee under the
Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or
assignment of mortgage without recourse) regarding the Mortgaged Property
subject to the Mortgage, which instrument of satisfaction or assignment, as the
case may be, shall be delivered to the Person or Persons entitled thereto
against receipt therefor of such payment, it being understood and agreed that no
expenses incurred in connection with such instrument of satisfaction or
assignment, as the case may be, shall be chargeable to the Protected Account.

        (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan and in accordance with the applicable Servicing
Agreement, the Trustee shall execute such documents as shall be prepared and
furnished to the Trustee by a Servicer or the Master Servicer (in

                                      -38-

<PAGE>

form reasonably acceptable to the Trustee) and as are necessary to the
prosecution of any such proceedings. The Custodian, on behalf of the Trustee,
shall, upon the request of a Servicer or the Master Servicer, and delivery to
the Custodian, on behalf of the Trustee, of two copies of a request for release
signed by a Servicing Officer substantially in the form of Exhibit D (or in a
mutually agreeable electronic format which will, in lieu of a signature on its
face, originate from a Servicing Officer), release the related Mortgage File
held in its possession or control to the Servicer or the Master Servicer, as
applicable. Such trust receipt shall obligate the Servicer or the Master
Servicer to return the Mortgage File to the Custodian on behalf of the Trustee,
when the need therefor by the Servicer or the Master Servicer no longer exists
unless the Mortgage Loan shall be liquidated, in which case, upon receipt of a
certificate of a Servicing Officer similar to that hereinabove specified, the
Mortgage File shall be released by the Custodian, on behalf of the Trustee, to
the Servicer or the Master Servicer.

        Section 3.08 DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF MASTER
SERVICER TO BE HELD FOR TRUSTEE.

        (a) The Master Servicer shall transmit and each Servicer (to the extent
required by the related Servicing Agreement) shall transmit to the Trustee or
Custodian such documents and instruments coming into the possession of the
Master Servicer or such Servicer from time to time as are required by the terms
hereof, or in the case of the Servicers, the applicable Servicing Agreement, to
be delivered to the Trustee or Custodian. Any funds received by the Master
Servicer or by a Servicer in respect of any Mortgage Loan or which otherwise are
collected by the Master Servicer or by a Servicer as Liquidation Proceeds or
Insurance Proceeds in respect of any Mortgage Loan shall be held for the benefit
of the Trustee and the Certificateholders subject to the Master Servicer's right
to retain or withdraw from the Master Servicer Collection Account the Master
Servicing Compensation and other amounts provided in this Agreement, and to the
right of each Servicer to retain its Servicing Fee and other amounts as provided
in the applicable Servicing Agreement. The Master Servicer shall, and (to the
extent provided in the applicable Servicing Agreement) shall cause each Servicer
to, provide access to information and documentation regarding the Mortgage Loans
to the Trustee, its agents and accountants at any time upon reasonable request
and during normal business hours, and to Certificateholders that are savings and
loan associations, banks or insurance companies, the Office of Thrift
Supervision, the FDIC and the supervisory agents and examiners of such Office
and Corporation or examiners of any other federal or state banking or insurance
regulatory authority if so required by applicable regulations of the Office of
Thrift Supervision or other regulatory authority, such access to be afforded
without charge but only upon reasonable request in writing and during normal
business hours at the offices of the Master Servicer designated by it. In
fulfilling such a request the Master Servicer shall not be responsible for
determining the sufficiency of such information.

        (b) All Mortgage Files and funds collected or held by, or under the
control of, the Master Servicer, in respect of any Mortgage Loans, whether from
the collection of principal and interest payments or from Liquidation Proceeds
or Insurance Proceeds, shall be held by the Master Servicer for and on behalf of
the Trustee and the Certificateholders and shall be and remain the sole and
exclusive property of the Trustee; provided, however, that the Master Servicer
and each Servicer shall be entitled to setoff against, and deduct from, any such
funds any amounts that are properly due

                                      -39-

and payable to the Master Servicer or such Servicer under this Agreement or the
applicable Servicing Agreement.

        Section 3.09   STANDARD HAZARD INSURANCE AND FLOOD INSURANCE POLICIES.

        (a) For each Mortgage Loan, the Master Servicer shall enforce any
obligation of the Servicers under the related Servicing Agreements to maintain
or cause to be maintained standard fire and casualty insurance and, where
applicable, flood insurance, all in accordance with the provisions of the
related Servicing Agreements. It is understood and agreed that such insurance
shall be with insurers meeting the eligibility requirements set forth in the
applicable Servicing Agreement and that no earthquake or other additional
insurance is to be required of any Mortgagor or to be maintained on property
acquired in respect of a defaulted loan, other than pursuant to such applicable
laws and regulations as shall at any time be in force and as shall require such
additional insurance.

        (b) Pursuant to Section 4.01 and 4.02, any amounts collected by the
Servicers or the Master Servicer, or by any Servicer, under any insurance
policies (other than amounts to be applied to the restoration or repair of the
property subject to the related Mortgage or released to the Mortgagor in
accordance with the applicable Servicing Agreement) shall be deposited into the
Master Servicer Collection Account, subject to withdrawal pursuant to Section
4.02 and 4.03. Any cost incurred by the Master Servicer or any Servicer in
maintaining any such insurance if the Mortgagor defaults in its obligation to do
so shall be added to the amount owing under the Mortgage Loan where the terms of
the Mortgage Loan so permit; provided, however, that the addition of any such
cost shall not be taken into account for purposes of calculating the
distributions to be made to Certificateholders and shall be recoverable by the
Master Servicer or such Servicer pursuant to Section 4.02 and 4.03.

        Section 3.10 PRESENTMENT OF CLAIMS AND COLLECTION OF PROCEEDS. The
Master Servicer shall (to the extent provided in the applicable Servicing
Agreement) cause the related Servicer to, prepare and present on behalf of the
Trustee and the Certificateholders all claims under the Insurance Policies and
take such actions (including the negotiation, settlement, compromise or
enforcement of the insured's claim) as shall be necessary to realize recovery
under such policies. Any proceeds disbursed to the Master Servicer (or disbursed
to a Servicer and remitted to the Master Servicer) in respect of such policies,
bonds or contracts shall be promptly deposited in the Master Servicer Collection
Account upon receipt, except that any amounts realized that are to be applied to
the repair or restoration of the related Mortgaged Property as a condition
precedent to the presentation of claims on the related Mortgage Loan to the
insurer under any applicable Insurance Policy need not be so deposited (or
remitted).

        Section 3.11   MAINTENANCE OF THE PRIMARY MORTGAGE INSURANCE POLICIES.

        (a) The Master Servicer shall not take, or permit any Servicer (to the
extent such action is prohibited under the applicable Servicing Agreement) to
take, any action that would result in noncoverage under any applicable Primary
Mortgage Insurance Policy of any loss which, but for the actions of such Master
Servicer or Servicer, would have been covered thereunder. The Master Servicer
shall use its best reasonable efforts to cause each Servicer (to the extent
required under the related Servicing Agreement) to keep in force and effect (to
the extent that the Mortgage Loan

                                      -40-

<PAGE>

requires the Mortgagor to maintain such insurance), primary mortgage insurance
applicable to each Mortgage Loan in accordance with the provisions of this
Agreement and the related Servicing Agreement, as applicable. The Master
Servicer shall not, and shall not permit any Servicer (to the extent required
under the related Servicing Agreement) to, cancel or refuse to renew any such
Primary Mortgage Insurance Policy that is in effect at the date of the initial
issuance of the Mortgage Note and is required to be kept in force hereunder
except in accordance with the provisions of this Agreement and the related
Servicing Agreement, as applicable.

        (b) The Master Servicer agrees to present, or to cause each Servicer (to
the extent required under the related Servicing Agreement) to present, on behalf
of the Trustee and the Certificateholders, claims to the insurer under any
Primary Mortgage Insurance Policies and, in this regard, to take such reasonable
action as shall be necessary to permit recovery under any Primary Mortgage
Insurance Policies respecting defaulted Mortgage Loans. Pursuant to Section 4.01
and 4.02, any amounts collected by the Master Servicer or any Servicer under any
Primary Mortgage Insurance Policies shall be deposited in the Master Servicer
Collection Account, subject to withdrawal pursuant to Section 4.03.

        Section 3.12   TRUSTEE TO RETAIN POSSESSION OF CERTAIN INSURANCE
                       POLICIES AND DOCUMENTS.

        The Trustee (or the Custodian, as directed by the Trustee), shall retain
possession and custody of the originals (to the extent available) of any Primary
Mortgage Insurance Policies, or certificate of insurance if applicable, and any
certificates of renewal as to the foregoing as may be issued from time to time
as contemplated by this Agreement. Until all amounts distributable in respect of
the Certificates have been distributed in full and the Master Servicer otherwise
has fulfilled its obligations under this Agreement, the Trustee (or its
Custodian, if any, as directed by the Trustee) shall also retain possession and
custody of each Mortgage File in accordance with and subject to the terms and
conditions of this Agreement. The Master Servicer shall promptly deliver or
cause to be delivered to the Trustee (or the Custodian, as directed by the
Trustee), upon the execution or receipt thereof the originals of any Primary
Mortgage Insurance Policies, any certificates of renewal, and such other
documents or instruments that constitute portions of the Mortgage File that come
into the possession of the Master Servicer from time to time.

        Section 3.13 REALIZATION UPON DEFAULTED MORTGAGE LOANS. The Master
Servicer shall cause each Servicer (to the extent required under the related
Servicing Agreement) to foreclose upon, repossess or otherwise comparably
convert the ownership of Mortgaged Properties securing such of the Mortgage
Loans as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments, all in
accordance with the applicable Servicing Agreement.

        Section 3.14   COMPENSATION FOR THE MASTER SERVICER.

        The Master Servicer will be entitled to all income and gain realized
from any investment of funds in the Distribution Account and the Master Servicer
Collection Account, pursuant to Article IV, for the performance of its
activities hereunder. Servicing compensation in the form of assumption fees, if
any, late payment charges, as collected, if any, or otherwise (but not including
any prepayment premium or penalty) shall be retained by the applicable Servicer
and shall not be

                                      -41-

<PAGE>

deposited in the Protected Account. The Master Servicer shall be required to pay
all expenses incurred by it in connection with its activities hereunder and
shall not be entitled to reimbursement therefor except as provided in this
Agreement.

        Section 3.15 REO PROPERTY.

        (a) In the event the Trust Fund acquires ownership of any REO Property
in respect of any related Mortgage Loan, the deed or certificate of sale shall
be issued to the Trustee, or to its nominee, on behalf of the related
Certificateholders. The Master Servicer shall, to the extent provided in the
applicable Servicing Agreement, cause the applicable Servicer to sell, any REO
Property as expeditiously as possible and in accordance with the provisions of
this Agreement and the related Servicing Agreement, as applicable. Pursuant to
its efforts to sell such REO Property, the Master Servicer shall cause the
applicable Servicer to protect and conserve, such REO Property in the manner and
to the extent required by the applicable Servicing Agreement, in accordance with
the REMIC Provisions and in a manner that does not result in a tax on "net
income from foreclosure property" or cause such REO Property to fail to qualify
as "foreclosure property" within the meaning of Section 860G(a)(8) of the Code.

        (b) The Master Servicer shall, to the extent required by the related
Servicing Agreement, cause the applicable Servicer to deposit all funds
collected and received in connection with the operation of any REO Property in
the Protected Account.

        (c) The Master Servicer and the applicable Servicer, upon the final
disposition of any REO Property, shall be entitled to reimbursement for any
related unreimbursed Monthly Advances and other unreimbursed advances as well as
any unpaid Servicing Fees from Liquidation Proceeds received in connection with
the final disposition of such REO Property; provided, that any such unreimbursed
Monthly Advances as well as any unpaid Servicing Fees may be reimbursed or paid,
as the case may be, prior to final disposition, out of any net rental income or
other net amounts derived from such REO Property.

        (d) To the extent provided in the related Servicing Agreement, the
Liquidation Proceeds from the final disposition of the REO Property, net of any
payment to the Master Servicer and the applicable Servicer as provided above
shall be deposited in the Protected Account on or prior to the Determination
Date in the month following receipt thereof and be remitted by wire transfer in
immediately available funds to the Master Servicer for deposit into the related
Master Servicer Collection Account on the next succeeding Servicer Remittance
Date.

        Section 3.16   ANNUAL OFFICER'S CERTIFICATE AS TO COMPLIANCE.

        (a) The Master Servicer shall deliver to the Trustee and the Rating
Agencies on or before May 31 of each year, commencing on May 31, 2003, an

activities of such Master Servicer during the preceding calendar year or portion
thereof and its performance under this Agreement, (ii) to the best of such
Servicing Officer's knowledge, based on such review, such Master Servicer has
performed and fulfilled its duties, responsibilities and obligations under this
Agreement in all material respects throughout such year, or, if there has been

                                      -42-

<PAGE>

a default in the fulfillment of any such duties, responsibilities or
obligations, specifying each such default known to such Servicing Officer and
the nature and status thereof, (iii) nothing has come to the attention of such
Servicing Officer to lead such Servicing Officer to believe that any Servicer
has failed to perform any of its duties, responsibilities and obligations under
its Servicing Agreement in all material respects throughout such year, or, if
there has been a material default in the performance or fulfillment of any such
duties, responsibilities or obligations, specifying each such default known to
such Servicing Officer and the nature and status thereof.

        (b) Copies of such statements shall be provided to any Certificateholder
upon request, by the Master Servicer or by the Trustee at the Master Servicer's
expense if the Master Servicer failed to provide such copies (unless (i) the
Master Servicer shall have failed to provide the Trustee with such statement or
(ii) the Trustee shall be unaware of the Master Servicer's failure to provide
such statement).

        Section 3.17 ANNUAL INDEPENDENT ACCOUNTANT'S SERVICING REPORT. If the
Master Servicer has, during the course of any fiscal year, directly serviced any
of the Mortgage Loans, then the Master Servicer at its expense shall cause a
nationally recognized firm of independent certified public accountants to
furnish a statement to the Trustee, the Rating Agencies and the Seller on or
before May 31 of each year, commencing on May 31, 2003 to the effect that, with
respect to the most recently ended fiscal year, such firm has examined certain
records and documents relating to the Master Servicer's performance of its
servicing obligations under this Agreement and pooling and servicing and trust
agreements in material respects similar to this Agreement and to each other and
that, on the basis of such examination conducted substantially in compliance
with the audit program for mortgages serviced for Freddie Mac or the Uniform
Single Attestation Program for Mortgage Bankers, such firm is of the opinion
that the Master Servicer's activities have been conducted in compliance with
this Agreement, or that such examination has disclosed no material items of
noncompliance except for (i) such exceptions as such firm believes to be
immaterial, (ii) such other exceptions as are set forth in such statement and
(iii) such exceptions that the Uniform Single Attestation Program for Mortgage
Bankers or the Audit Program for Mortgages Serviced by Freddie Mac requires it
to report. Copies of such statements shall be provided to any Certificateholder
upon request by the Master Servicer, or by the Trustee at the expense of the
Master Servicer if the Master Servicer shall fail to provide such copies. If
such report discloses exceptions that are material, the Master Servicer shall
advise the Trustee whether such exceptions have been or are susceptible of cure,
and will take prompt action to do so.

        Section 3.18 REPORTS FILED WITH SECURITIES AND EXCHANGE COMMISSION.
Within 15 days after each Distribution Date, the Securities Administrator shall,
in accordance with industry standards, file with the Commission via the
Electronic Data Gathering and Retrieval System ("EDGAR"), a Form 8-K with a copy
of the statement to the Trustee who shall furnish a copy of the statement to the
Certificateholders for such Distribution Date as an exhibit thereto. Prior to
January 30, 2003, the Securities Administrator shall, in accordance with
industry standards and only if instructed by the Seller, file a Form 15
Suspension Notice with respect to the Trust Fund, if applicable. Prior to March
30, 2003, the Securities Administrator shall file a Form 10-K, in substance
conforming to industry standards, with respect to the Trust Fund. The Seller
hereby grants to the Securities Administrator a limited power of attorney to
execute and file each such document on behalf of the Seller. Such power of
attorney shall continue until either the earlier of (i) receipt by the
Securities Administrator

                                      -43-

<PAGE>

from the Seller of written termination of such power of attorney and (ii) the
termination of the Trust Fund. The Seller agrees to promptly furnish to the
Securities Administrator, from time to time upon request, such further
information, reports and financial statements within its control related to this
Agreement and the Mortgage Loans as the Securities Administrator reasonably
deems appropriate to prepare and file all necessary reports with the Commission.
The Securities Administrator shall have no responsibility to file any items
other than those specified in this Section 3.18; provided, however, the
Securities Administrator will cooperate with the Seller in connection with any
additional filings with respect to the Trust Fund as the Seller deems necessary
under the Securities Exchange Act of 1934, as amended (the "Exchange Act").
Copies of all reports filed by the Securities Administrator under the Exchange
Act shall be sent to: the Seller c/o Bear, Stearns & Co. Inc., Attn: Managing
Director-Analysis and Control, One Metrotech Center North, Brooklyn, New York
11202- 3859. Fees and expenses incurred by the Securities Administrator in
connection with this Section 3.18 shall not be reimbursable from the Trust Fund.

a payment of $5,000.

        Section 3.20 UCC. The Trustee agrees to file continuation statements for
any Uniform Commercial Code financing statements which the Seller has informed
the Trustee were filed on the Closing Date in connection with the Trust. The
Seller shall file any financing statements or amendments thereto required by any
change in the Uniform Commercial Code.

        Section 3.21   OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS.

        With respect to any Mortgage Loan which as of the first day of a
Calendar Quarter is delinquent in payment by 90 days or more or is an REO
Property, EMC shall have the right to purchase such Mortgage Loan from the Trust
at a price equal to the Repurchase Price; provided however (i) that such
Mortgage Loan is still 90 days or more delinquent or is an REO Property as of
the date of such purchase and (ii) this purchase option, if not theretofore
exercised, shall terminate on the date prior to the last day of the related
Calendar Quarter. This purchase option, if not exercised, shall not be
thereafter reinstated unless the delinquency is cured and the Mortgage Loan
thereafter again becomes 90 days or more delinquent or becomes an REO Property,
in which case the option shall again become exercisable as of the first day of
the related Calendar Quarter.

        If at any time EMC remits to the Master Servicer a payment for deposit
in the Master Servicer Collection Account covering the amount of the Repurchase
Price for such a Mortgage Loan, and EMC provides to the Trustee a certification
signed by a Servicing Officer stating that the amount of such payment has been
deposited in the Master Servicer Collection Account, then the Trustee shall
execute the assignment of such Mortgage Loan at the request of EMC without
recourse to EMC which shall succeed to all the Trustee's right, title and
interest in and to such Mortgage Loan, and all security and documents relative
thereto. Such assignment shall be an assignment outright and not for security.
EMC will thereupon own such Mortgage, and all such security and documents, free
of any further obligation to the Trustee or the Certificateholders with respect
thereto.

trust in its Corporate Trust Office, and the Distribution Account and the funds
deposited therein shall not be subject to, and shall be protected from, all
claims, liens, and encumbrances of any creditors or depositors of the Trustee or

                                  Certificates

        Section 5.01 CERTIFICATES. (a) The Depository, the Seller and the
Trustee have entered into a Depository Agreement dated as of the Closing Date
(the "Depository Agreement"). Except for the Residual Certificates, the Private
Certificates and the Individual Certificates and as provided in Subsection
5.01(b), the Certificates shall at all times remain registered in the name of
the Depository or its nominee and at all times: (i) registration of such
Certificates may not be transferred by the Trustee except to a successor to the
Depository; (ii) ownership and transfers of registration of such Certificates on
the books of the Depository shall be governed by applicable rules established by
the Depository; (iii) the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants; (iv) the Trustee shall
deal with the Depository as representative of such Certificate Owners of the
respective Class of Certificates for purposes of exercising the rights of
Certificateholders under this Agreement, and requests and directions for and
votes of such representative shall not be deemed to be inconsistent if they are
made with respect to different Certificate Owners; and (v) the Trustee may rely
and shall be fully protected in relying upon information furnished by the
Depository with respect to its Depository Participants.

        The Residual Certificates and the Private Certificates are initially
Physical Certificates. If at any time the Holders of all of the Certificates of
one or more such Classes request that the Trustee cause such Class to become
Global Certificates, the Trustee and the Seller will take such action as may be
reasonably required to cause the Depository to accept such Class or Classes for
trading if it may legally be so traded.

        All transfers by Certificate Owners of such respective Classes of
Book-Entry Certificates and any Global Certificates shall be made in accordance
with the procedures established by the Depository Participant or brokerage firm
representing such Certificate Owners. Each Depository Participant shall only
transfer Book-Entry Certificates of Certificate Owners it represents or of
brokerage firms for which it acts as agent in accordance with the Depository's
normal procedures.

        (b) If (i)(A) the Seller advises the Trustee in writing that the
Depository is no longer willing or able to properly discharge its
responsibilities as Depository and (B) the Trustee or the Seller is unable to
locate a qualified successor within 30 days or (ii) the Seller at its option
advises the Trustee in writing that it elects to terminate the book-entry system
through the Depository, the Trustee shall request that the Depository notify all
Certificate Owners of the occurrence of any such event and of the availability
of definitive, fully registered Certificates to Certificate Owners requesting
the same. Upon surrender to the Trustee of the Certificates by the Depository,
accompanied by registration instructions from the Depository for registration,
the Trustee shall issue the definitive Certificates. Neither the Seller nor the
Trustee shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.

        (c) (i) REMIC I will be evidenced by (x) the REMIC I Regular Interests
(designated below), which will be uncertificated and non-transferable and are
hereby designated as the "regular interests" in REMIC I and (y) the Class R-I
Certificates, which is hereby designated as the single

                                      -51-

<PAGE>

"residual interest" in REMIC I. Distributions shall be deemed to be made to the
REMIC I Regular Interests first, so as to keep the Uncertificated Principal
Balance of each REMIC I Regular Interest ending with the designation "B" equal
to 0.01% of the aggregate Scheduled Principal Balance of the Mortgage Loans in
the related Group; second, to each REMIC I Regular Interest ending with the
designation "A," so that the Uncertificated Principal Balance of each such REMIC
I Regular Interest is equal to 0.01% of the excess of (x) the aggregate
Scheduled Principal Balance of the Mortgage Loans in the related Group over (y)
the Current Principal Amount of the Senior Certificate in the related Group
(except that if any such excess is a larger number than in the preceding
distribution period, the least amount of principal shall be distributed to such
REMIC I Regular Interests such that the REMIC I Subordinated Balance Ratio is
maintained); and third, any remaining principal to REMIC I Regular Interest ZZZ.
Realized Losses shall be applied after all distributions have been made on each
Distribution Date first, so as to keep the Uncertificated Principal Balance of
each REMIC I Regular Interest ending with the designation "B" equal to 0.01% of
the aggregate Scheduled Principal Balance of the Mortgage Loans in the related
Group; second, to each REMIC I Regular Interest ending with the designation "A,"
so that the Uncertificated Principal Balance of each such REMIC I Regular
Interest is equal to 0.01% of the excess of (x) the aggregate Scheduled
Principal Balance of the Mortgage Loans in the related Group over (y) the
Current Principal Amount of the Senior Certificate in the related Group (except
that if any such excess is a larger number than in the preceding distribution
period, the least amount of Realized Losses shall be applied to such REMIC I
Regular Interests such that the REMIC I Subordinated Balance Ratio is
maintained); and third, the remaining Realized Losses shall be allocated to
REMIC I Regular Interest ZZZ.

        The REMIC I Regular Certificates and the Class R-I Certificates will
have the following designations and pass-through rates:

hereby designated as the "regular interests" in REMIC II and have the principal
balances and accrue interest at the Pass-Through Rates

equal to those set forth in Section 5.01(d) and (y) the Class R-II Certificate,
which is hereby designated as the single "residual interest" in REMIC II.

        The Classes of the Certificates shall have the following designations,
initial principal amounts and Pass-Through Rates:

------------------------------

         (1) The Class I-A will bear interest at a variable Pass-Through Rate
equal to the weighted average of the Net Rates of the Group 1 Mortgage Loans,
weighted on the basis of the respective Scheduled Principal Balances of each
such Mortgage Loan as of the beginning of the Due Period immediately preceding
the related Distribution Date. The Pass-Through Rate with respect to the first
Interest Accrual Period is expected to be approximately 6.215% per annum.

         (2) The Class II-A, Class R-I and Class R-II Certificates will bear
interest at a variable Pass-Through Rate equal to the weighted average of the
Net Rates of the Group 2 Mortgage Loans, weighted on the basis of the respective
Scheduled Principal Balances of each such Mortgage Loan as of the beginning of
the Due Period immediately preceding the related Distribution Date. The
Pass-Through Rate with respect to the first Interest Accrual Period is expected
to be approximately 6.116% per annum.

         (3) The Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class
B-6 Certificates will bear interest at a variable Pass-Through Rate equal to the
weighted average of the Pass-Through Rates on each REMIC I Regular Interest
ending with the designation "A"; provided that for purposes of such weighted
average, the Pass-Through Rate of each such REMIC I Regular Interest shall be
subject to a cap and a floor equal to the weighted average of the Net Rates of
the Mortgage Loans in the Related Group. The Pass-Through Rate with respect to
the first interest accrual period is expected to be approximately 6.159% per
annum.

        (d) Solely for purposes of Section 1.860G-1(a)(4)(iii) of the Treasury
regulations, the Distribution Date immediately following the maturity date for
the Mortgage Loan with the latest maturity date in the Trust Fund has been
designated as the "latest possible maturity date" for the REMIC I Regular
Interests and the Certificates.

        (e) With respect to each Distribution Date, each Class of Certificates
shall accrue interest during the related Interest Accrual Period. With respect
to each Distribution Date and each such Class of Certificates, interest shall be
calculated, on the basis of a 360-day year comprised of twelve 30-day months,
based upon the respective Pass-Through Rate set forth, or determined as
provided, above and the Current Principal Amount of such Class applicable to
such Distribution Date.

                                      -53-

        (f) The Certificates shall be substantially in the forms set forth in
Exhibits A-1, A-2 and A-3. On original issuance, the Trustee shall sign,
countersign and shall deliver them at the direction of the Seller. Pending the
preparation of definitive Certificates of any Class, the Trustee may sign and
countersign temporary Certificates that are printed, lithographed or
typewritten, in authorized denominations for Certificates of such Class,
substantially of the tenor of the definitive Certificates in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers or authorized signatories executing such
Certificates may determine, as evidenced by their execution of such
Certificates. If temporary Certificates are issued, the Seller will cause
definitive Certificates to be prepared without unreasonable delay. After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office of the Trustee, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Certificates, the
Trustee shall sign and countersign and deliver in exchange therefor a like
aggregate principal amount, in authorized denominations for such Class, of
definitive Certificates of the same Class. Until so exchanged, such temporary
Certificates shall in all respects be entitled to the same benefits as
definitive Certificates.

        (g) Each Class of Book-Entry Certificates will be registered as a single
Certificate of such Class held by a nominee of the Depository or the DTC
Custodian, and beneficial interests will be held by investors through the
book-entry facilities of the Depository in minimum denominations of (i) in the
case of the Senior Certificates (other than the Residual Certificates), $1,000
and in each case increments of $1.00 in excess thereof, and (ii) in the case of
the Offered Subordinate Certificates, $25,000 and increments of $1.00 in excess
thereof, except that one Certificate of each such Class may be issued in a
different amount so that the sum of the denominations of all outstanding
Certificates of such Class shall equal the Current Principal Amount of such
Class on the Closing Date. On the Closing Date, the Trustee shall execute and
countersign Physical Certificates all in an aggregate principal amount that
shall equal the Current Principal Amount of such Class on the Closing Date. The
Private Certificates shall be issued in certificated fully-registered form in
minimum dollar denominations of $25,000 and integral multiples of $1.00 in
excess thereof, except that one Private Certificate of each Class may be issued
in a different amount so that the sum of the denominations of all outstanding
Private Certificates of such Class shall equal the Current Principal Amount of
such Class on the Closing Date. The Residual Certificates shall each be issued
in certificated fully-registered form in the denomination of $50 and $50,
respectively. Each Class of Global Certificates, if any, shall be issued in
fully registered form in minimum dollar denominations of $50,000 and integral
multiples of $1.00 in excess thereof, except that one Certificate of each Class
may be in a different denomination so that the sum of the denominations of all
outstanding Certificates of such Class shall equal the Current Principal Amount
of such Class on the Closing Date. On the Closing Date, the Trustee shall
execute and countersign (i) in the case of each Class of Offered Certificates,
the Certificate in the entire Current Principal Amount of the respective Class
and (ii) in the case of each Class of Private Certificates, Individual
Certificates all in an aggregate principal amount that shall equal the Current
Principal Amount of each such respective Class on the Closing Date. The
Certificates referred to in clause (i) and if at any time there are to be Global
Certificates, the Global Certificates shall be delivered by the Seller to the
Depository or pursuant to the Depository's instructions, shall be delivered by
the Seller on behalf of the Depository to and deposited with the DTC Custodian.
The Trustee shall sign the Certificates by facsimile or manual signature and
countersign them by manual signature on behalf of the Trustee by one or more

                                      -54-

<PAGE>

authorized signatories, each of whom shall be Responsible Officers of the
Trustee or its agent. A Certificate bearing the manual and facsimile signatures
of individuals who were the authorized signatories of the Trustee or its agent
at the time of issuance shall bind the Trustee, notwithstanding that such
individuals or any of them have ceased to hold such positions prior to the
delivery of such Certificate.

        (h) No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless there appears on such Certificate
the manually executed countersignature of the Trustee or its agent, and such
countersignature upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly executed and delivered hereunder.
All Certificates issued on the Closing Date shall be dated the Closing Date. All
Certificates issued thereafter shall be dated the date of their
countersignature.

        (i) The Closing Date is hereby designated as the "startup" day of each
REMIC within the meaning of Section 860G(a)(9) of the Code.

        (j) For federal income tax purposes, each REMIC shall have a tax year
that is a calendar year and shall report income on an accrual basis.

        (k) The Trustee on behalf of the Trust shall cause each REMIC to timely
elect to be treated as a REMIC under Section 860D of the Code. Any
inconsistencies or ambiguities in this Agreement or in the administration of any
Trust established hereby shall be resolved in a manner that preserves the
validity of such elections.

        (l) The following legend shall be placed on the Residual Certificates
and Private Certificates, whether upon original issuance or upon issuance of any
other Certificate of any such Class in exchange therefor or upon transfer
thereof:

        THIS CERTIFICATE MAY NOT BE ACQUIRED DIRECTLY OR INDIRECTLY BY, OR ON

        Section 5.02 REGISTRATION OF TRANSFER AND EXCHANGE OF CERTIFICATES. (a)
The Trustee shall maintain at its Corporate Trust Office a Certificate Register
in which, subject to such reasonable regulations as it may prescribe, the
Trustee shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided.

        (b) Subject to Subsection 5.01(a) and, in the case of any Global
Certificate or Physical Certificate upon the satisfaction of the conditions set
forth below, upon surrender for registration of transfer of any Certificate at
any office or agency of the Trustee maintained for such purpose, the Trustee
shall sign, countersign and shall deliver, in the name of the designated
transferee or transferees, a new Certificate of a like Class and aggregate
Fractional Undivided Interest, but bearing a different number.

        (c) By acceptance of an Individual Certificate, whether upon original
issuance or subsequent transfer, each holder of such a Certificate acknowledges
the restrictions on the transfer of such Certificate set forth in the Securities
Legend and agrees that it will transfer such a Certificate only as provided
herein. In addition to the provisions of Subsection 5.02(h), the following
restrictions shall apply with respect to the transfer and registration of
transfer of an Individual Certificate to a transferee that takes delivery in the
form of an Individual Certificate:

               (i) The Trustee shall register the transfer of an Individual
        Certificate if the requested transfer is being made to a transferee who
        has provided the Trustee with a Rule 144A Certificate or comparable
        evidence as to its QIB status.

               (ii) The Trustee shall register the transfer of any Individual
        Certificate if (x) the transferor has advised the Trustee in writing
        that the Certificate is being transferred to an Institutional Accredited
        Investor; and (y) prior to the transfer the transferee furnishes to the
        Trustee an Investment Letter (and the Trustee shall be fully protected
        in so doing), provided that, if based upon an Opinion of Counsel to the
        effect that the delivery of (x) and (y) above are not sufficient to
        confirm that the proposed transfer is being made pursuant to an
        exemption from, or in a transaction not subject to, the registration
        requirements of the Securities Act and other applicable laws, the
        Trustee shall as a condition of the registration of any such transfer
        require the transferor to furnish such other certifications, legal
        opinions or other information prior to registering the transfer of an
        Individual Certificate as shall be set forth in such Opinion of Counsel.

        (d) Subject to Subsection 5.02(h), so long as a Global Certificate of
such Class is outstanding and is held by or on behalf of the Depository,
transfers of beneficial interests in such Global Certificate, or transfers by
holders of Individual Certificates of such Class to transferees that take
delivery in the form of beneficial interests in the Global Certificate, may be
made only in accordance with this Subsection 5.02(d) and in accordance with the
rules of the Depository:

               (i) In the case of a beneficial interest in the Global
        Certificate being transferred to an Institutional Accredited Investor,
        such transferee shall be required to take delivery in

                                      -56-

<PAGE>

        the form of an Individual Certificate or Certificates and the Trustee
        shall register such transfer only upon compliance with the provisions of
        Subsection 5.02(c)(ii).

               (ii) In the case of a beneficial interest in a Class of Global
        Certificates being transferred to a transferee that takes delivery in
        the form of an Individual Certificate or Certificates of such Class,
        except as set forth in clause (i) above, the Trustee shall register such
        transfer only upon compliance with the provisions of Subsection
        5.02(c)(i).

               (iii) In the case of an Individual Certificate of a Class being
        transferred to a transferee that takes delivery in the form of a
        beneficial interest in a Global Certificate of such Class, the Trustee
        shall register such transfer if the transferee has provided the Trustee
        with a Rule 144A Certificate or comparable evidence as to its QIB
        status.

               (iv) No restrictions shall apply with respect to the transfer or
        registration of transfer of a beneficial interest in the Global
        Certificate of a Class to a transferee that takes delivery in the form
        of a beneficial interest in the Global Certificate of such Class;
        provided that each such transferee shall be deemed to have made such
        representations and warranties contained in the Rule 144A Certificate as
        are sufficient to establish that it is a QIB.

        (e) Subject to Subsection 5.02(h), an exchange of a beneficial interest
in a Global Certificate of a Class for an Individual Certificate or Certificates
of such Class, an exchange of an Individual Certificate or Certificates of a
Class for a beneficial interest in the Global Certificate of such Class and an
exchange of an Individual Certificate or Certificates of a Class for another
Individual Certificate or Certificates of such Class (in each case, whether or
not such exchange is made in anticipation of subsequent transfer, and, in the
case of the Global Certificate of such Class, so long as such Certificate is
outstanding and is held by or on behalf of the Depository) may be made only in
accordance with this Subsection 5.02(e) and in accordance with the rules of the
Depository:

               (i) A holder of a beneficial interest in a Global Certificate of
        a Class may at any time exchange such beneficial interest for an
        Individual Certificate or Certificates of such Class.

               (ii) A holder of an Individual Certificate or Certificates of a
        Class may exchange such Certificate or Certificates for a beneficial
        interest in the Global Certificate of such Class if such holder
        furnishes to the Trustee a Rule 144A Certificate or comparable evidence
        as to its QIB status.

               (iii) A holder of an Individual Certificate of a Class may
        exchange such Certificate for an equal aggregate principal amount of
        Individual Certificates of such Class in different authorized
        denominations without any certification.

        (f) (i) Upon acceptance for exchange or transfer of an Individual
Certificate of a Class for a beneficial interest in a Global Certificate of such
Class as provided herein, the Trustee shall cancel such Individual Certificate
and shall (or shall request the Depository to) endorse on the schedule affixed
to the applicable Global Certificate (or on a continuation of such schedule
affixed to the Global Certificate and made a part thereof) or otherwise make in
its books and records an

                                      -57-

<PAGE>

appropriate notation evidencing the date of such exchange or transfer and an
increase in the certificate balance of the Global Certificate equal to the
certificate balance of such Individual Certificate exchanged or transferred
therefor.

               (ii) Upon acceptance for exchange or transfer of a beneficial
        interest in a Global Certificate of a Class for an Individual
        Certificate of such Class as provided herein, the Trustee shall (or
        shall request the Depository to) endorse on the schedule affixed to such
        Global Certificate (or on a continuation of such schedule affixed to
        such Global Certificate and made a part thereof) or otherwise make in
        its books and records an appropriate notation evidencing the date of
        such exchange or transfer and a decrease in the certificate balance of
        such Global Certificate equal to the certificate balance of such
        Individual Certificate issued in exchange therefor or upon transfer
        thereof.

        (g) The Securities Legend shall be placed on any Individual Certificate
issued in exchange for or upon transfer of another Individual Certificate or of
a beneficial interest in a Global Certificate.

        (h) Subject to the restrictions on transfer and exchange set forth in
this Section 5.02, the holder of any Individual Certificate may transfer or
exchange the same in whole or in part (in an initial certificate balance equal
to the minimum authorized denomination set forth in Section 5.01(h) above or any
integral multiple of $1.00 in excess thereof) by surrendering such Certificate
at the Corporate Trust Office, or at the office of any transfer agent, together
with an executed instrument of assignment and transfer satisfactory in form and
substance to the Trustee in the case of transfer and a written request for
exchange in the case of exchange. The holder of a beneficial interest in a
Global Certificate may, subject to the rules and procedures of the Depository,
cause the Depository (or its nominee) to notify the Trustee in writing of a
request for transfer or exchange of such beneficial interest for an Individual
Certificate or Certificates. Following a proper request for transfer or
exchange, the Trustee shall, within five Business Days of such request made at
such Corporate Trust Office, sign, countersign and deliver at such Corporate
Trust Office, to the transferee (in the case of transfer) or holder (in the case
of exchange) or send by first class mail at the risk of the transferee (in the
case of transfer) or holder (in the case of exchange) to such address as the
transferee or holder, as applicable, may request, an Individual Certificate or
Certificates, as the case may require, for a like aggregate Fractional Undivided
Interest and in such authorized denomination or denominations as may be
requested. The presentation for transfer or exchange of any Individual
Certificate shall not be valid unless made at the Corporate Trust Office by the
registered holder in person, or by a duly authorized attorney-in-fact.

        (i) At the option of the Certificateholders, Certificates may be
exchanged for other Certificates of authorized denominations of a like Class and
aggregate Fractional Undivided Interest, upon surrender of the Certificates to
be exchanged at any such office or agency; provided, however, that no
Certificate may be exchanged for new Certificates unless the original Fractional
Undivided Interest represented by each such new Certificate (i) is at least
equal to the minimum authorized denomination or (ii) is acceptable to the Seller
as indicated to the Trustee in writing. Whenever any Certificates are so
surrendered for exchange, the Trustee shall sign and countersign and the Trustee
shall deliver the Certificates which the Certificateholder making the exchange
is entitled to receive.

                                      -58-

<PAGE>

        (j) If the Trustee so requires, every Certificate presented or
surrendered for transfer or exchange shall be duly endorsed by, or be
accompanied by a written instrument of transfer, with a signature guarantee, in
form satisfactory to the Trustee, duly executed by the holder thereof or his or
her attorney duly authorized in writing.

        (k) No service charge shall be made for any transfer or exchange of
Certificates, but the Trustee may require payment of a sum sufficient to cover
any tax or governmental charge that may be imposed in connection with any
transfer or exchange of Certificates.

        (l) The Trustee shall cancel all Certificates surrendered for transfer
or exchange but shall retain such Certificates in accordance with its standard
retention policy or for such further time as is required by the record retention
requirements of the Securities Exchange Act of 1934, as amended, and thereafter
may destroy such Certificates.

        Section 5.03 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES. (a) If
(i) any mutilated Certificate is surrendered to the Trustee, or the Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and (ii) there is delivered to the Trustee such security or
indemnity as it may require to save it harmless, and (iii) the Trustee has not
received notice that such Certificate has been acquired by a third Person, the
Trustee shall sign, countersign and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and Fractional Undivided Interest but in each case bearing a different
number. The mutilated, destroyed, lost or stolen Certificate shall thereupon be
canceled of record by the Trustee and shall be of no further effect and evidence
no rights.

        (b) Upon the issuance of any new Certificate under this Section 5.03,
the Trustee may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
Any duplicate Certificate issued pursuant to this Section 5.03 shall constitute
complete and indefeasible evidence of ownership in the Trust Fund, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

        Section 5.04 PERSONS DEEMED OWNERS. Prior to due presentation of a
Certificate for registration of transfer, the Seller, the Trustee and any agent
of the Seller or the Trustee may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving
distributions pursuant to Section 6.01 and for all other purposes whatsoever.
Neither the Seller, the Trustee nor any agent of the Seller or the Trustee shall
be affected by notice to the contrary. No Certificate shall be deemed duly
presented for a transfer effective on any Record Date unless the Certificate to
be transferred is presented no later than the close of business on the third
Business Day preceding such Record Date.

        Section 5.05 TRANSFER RESTRICTIONS ON RESIDUAL CERTIFICATES. (a)
Residual Certificates, or interests therein, may not be transferred without the
prior express written consent of the Tax Matters Person and the Seller. As a
prerequisite to such consent, the proposed transferee must provide the Tax
Matters Person, the Seller and the Trustee with an affidavit that the proposed
transferee is a Permitted Transferee (and, unless the Tax Matters Person and the
Seller consent to the transfer to a person who is not a U.S. Person, an
affidavit that it is a U.S. Person) as provided in Subsection 5.05(b).

        (b) No transfer, sale or other disposition of a Residual Certificate
(including a beneficial interest therein) may be made unless, prior to the
transfer, sale or other disposition of a Residual Certificate, the proposed
transferee (including the initial purchasers thereof) delivers to the Tax
Matters Person, the Trustee and the Seller an affidavit in the form attached
hereto as Exhibit E stating, among other things, that as of the date of such
transfer (i) such transferee is a Permitted Transferee and that (ii) such
transferee is not acquiring such Residual Certificate for the account of any
person who is not a Permitted Transferee. The Tax Matters Person shall not
consent to a transfer of a Residual Certificate if it has actual knowledge that
any statement made in the affidavit issued pursuant to the preceding sentence is
not true. Notwithstanding any transfer, sale or other disposition of a Residual
Certificate to any Person who is not a Permitted Transferee, such transfer, sale
or other disposition shall be deemed to be of no legal force or effect
whatsoever and such Person shall not be deemed to be a Holder of a Residual
Certificate for any purpose hereunder, including, but not limited to, the
receipt of distributions thereon. If any purported transfer shall be in
violation of the provisions of this Subsection 5.05(b), then the prior Holder
thereof shall, upon discovery that the transfer of such Residual Certificate was
not in fact permitted by this Subsection 5.05(b), be restored to all rights as a
Holder thereof retroactive to the date of the purported transfer. None of the
Trustee, the Tax Matters Person or the Seller shall be under any liability to
any Person for any registration or transfer of a Residual Certificate that is
not permitted by this Subsection 5.05(b) or for making payments due on such
Residual Certificate to the purported Holder thereof or taking any other action
with respect to such purported Holder under the provisions of this Agreement so
long as the written affidavit referred to above was received with respect to
such transfer, and the Tax Matters Person, the Trustee and the Seller, as
applicable, had no knowledge that it was untrue. The prior Holder shall be
entitled to recover from any purported Holder of a Residual Certificate that was
in fact not a permitted transferee under this Subsection 5.05(b) at the time it
became a Holder all payments made on such Residual Certificate. Each Holder of a
Residual Certificate, by acceptance thereof, shall be deemed for all purposes to
have consented to the provisions of this Subsection 5.05(b) and to any amendment
of this Agreement deemed necessary (whether as a result of new legislation or
otherwise) by counsel of the Tax Matters Person or the Seller to ensure that the
Residual Certificates are not transferred to any Person who is not a Permitted
Transferee and that any transfer of such Residual Certificates will not cause
the imposition of a tax upon the Trust or cause any REMIC to fail to qualify as
a REMIC.

        (c) Unless the Tax Matters Person shall have consented in writing (which
consent may be withheld in the Tax Matters Person's sole discretion), the
Residual Certificates (including a beneficial interest therein) may not be
purchased by or transferred to any person who is not a United States Person.

                                      -60-

        (d) By accepting a Residual Certificate, the purchaser thereof agrees to
be a Tax Matters Person, and appoints the Securities Administrator to act as its
agent with respect to all matters concerning the tax obligations of the Trust.

        Section 5.06 RESTRICTIONS ON TRANSFERABILITY OF CERTIFICATES. (a) No
offer, sale, transfer or other disposition (including pledge) of any Certificate
shall be made by any Holder thereof unless registered under the Securities Act,
or an exemption from the registration requirements of the Securities Act and any
applicable state securities or "Blue Sky" laws is available and the prospective
transferee (other than the Seller) of such Certificate signs and delivers to the
Trustee an Investment Letter, if the transferee is an Institutional Accredited
Investor, in the form set forth as Exhibit F-l hereto, or a Rule 144A
Certificate, if the transferee is a QIB, in the form set forth as Exhibit F-2
hereto. Notwithstanding the provisions of the immediately preceding sentence, no
restrictions shall apply with respect to the transfer or registration of
transfer of a beneficial interest in any Certificate that is a Global
Certificate of a Class to a transferee that takes delivery in the form of a
beneficial interest in the Global Certificate of such Class provided that each
such transferee shall be deemed to have made such representations and warranties
contained in the Rule 144A Certificate as are sufficient to establish that it is
a QIB. In the case of a proposed transfer of any Certificate to a transferee
other than a QIB, the Trustee may require an Opinion of Counsel that such
transaction is exempt from the registration requirements of the Securities Act.
The cost of such opinion shall not be an expense of the Trustee or the Trust
Fund.

        (b)    The Private Certificates shall each bear a Securities Legend.

        Section 5.07 ERISA RESTRICTIONS. (a) Subject to the provisions of
subsection (b), no Residual Certificates or Private Certificates may be acquired
directly or indirectly by, or on behalf of, an employee benefit plan or other
retirement arrangement which is subject to Title I of ERISA and/or Section 4975
of the Code, unless the proposed transferee provides either (i) the Trustee, the
Master Servicer and the Securities Administrator with an Opinion of Counsel
satisfactory to the Trustee, the Master Servicer and the Securities
Administrator, which opinion will not be at the expense of the Trustee, the
Master Servicer or the Securities Administrator, that the purchase of such
Certificates by or on behalf of such Plan is permissible under applicable law,
will not constitute or result in a nonexempt prohibited transaction under ERISA
or Section 4975 of the Code and will not subject the Trustee, the Master
Servicer or the Securities Administrator to any obligation in addition to those
undertaken in the Agreement or (ii) in the case of the Class B-4, Class B-5 and
Class B-6 Certificates, a representation or certification to the Trustee (upon
which the Trustee is authorized to rely) to the effect that the proposed
transfer and/or holding of such a Certificate and the servicing, management and
operation of the Trust: (I) will not result in a prohibited transaction under
Section 406 of ERISA or Section 4975 of the Code which is not covered under an
individual or class prohibited transaction exemption including but not limited
to Department of Labor Prohibited Transaction Exemption ("PTE") 84-14 (Class
Exemption for Plan Asset Transactions Determined by Independent Qualified
Professional Asset Managers); PTE 91-38 (Class Exemption for Certain
Transactions Involving Bank Collective Investment Funds); PTE 90-1 (Class
Exemption for Certain Transactions Involving Insurance Company Pooled Separate
Accounts), PTE 95-60 (Class Exemption for Certain Transactions Involving
Insurance Company General Accounts), and PTCE 96-23 (Class Exemption for Plan
Asset Transactions Determined by In-House Asset Managers and

                                      -61-

<PAGE>

(II) will not subject the Seller, the Securities Administrator, the Master
Servicer or the Trustee to any obligation in addition to those undertaken in the
Agreement.

        (b) Any Person acquiring an interest in a Global Certificate which is a
Private Certificate, by acquisition of such Certificate, shall be deemed to have
represented to the Trustee that in the case of the Class B-4, Class B-5 and
Class B-6 Certificates, either: (i) it is not acquiring an interest in such
Certificate directly or indirectly by, or on behalf of, an employee benefit plan
or other retirement arrangement which is subject to Title I of ERISA and/or
Section 4975 of the Code, or (ii) the transfer and/or holding of an interest in
such Certificate to that Person and the subsequent servicing, management and/or
operation of the Trust and its assets: (I) will not result in any prohibited
transaction which is not covered under an individual or class prohibited
transaction exemption, including, but not limited to, PTE 84-14, PTE 91-38, PTE
90-1, PTE 95-60 or PTE 96- 23 and (II) will not subject the Seller, the
Securities Administrator, the Master Servicer or the Trustee to any obligation
in addition to those undertaken in the Agreement.

        (c) Neither the Trustee, the Master Servicer nor the Securities
Administrator will be required to monitor, determine or inquire as to compliance
with the transfer restrictions with respect to the Global Certificates. Any
attempted or purported transfer of any Certificate in violation of the
provisions of Subsections (a) or (b) above shall be void ab initio and such
Certificate shall be considered to have been held continuously by the prior
permitted Certificateholder. Any transferor of any Certificate in violation of
such provisions, shall indemnify and hold harmless the Trustee, the Securities
Administrator and the Master Servicer from and against any and all liabilities,
claims, costs or expenses incurred by the Trustee, the Securities Administrator
or the Master Servicer as a result of such attempted or purported transfer. The
Trustee shall have no liability for transfer of any such Global Certificates in
or through book-entry facilities of any Depository or between or among
Depository Participants or Certificate Owners made in violation of the transfer
restrictions set forth herein.

        Section 5.08 RULE 144A INFORMATION. For so long as any Certificates are
outstanding and are "restricted securities" within the meaning of Rule 144(a)(3)
of the Securities Act, (1) the Seller will provide or cause to be provided to
any holder of such Certificates and any prospective purchaser thereof designated
by such a holder, upon the request of such holder or prospective purchaser, the
information required to be provided to such holder or prospective purchaser by
Rule 144A(d)(4) under the Securities Act; and (2) the Seller shall update such
information from time to time in order to prevent such information from becoming
false and misleading and will take such other actions as are necessary to ensure
that the safe harbor exemption from the registration requirements of the
Securities Act under Rule 144A is and will be available for resales of such
Certificates conducted in accordance with Rule 144A.

                       third, to the Group 1 Senior Certificates, in reduction

               B-2, Class B-3, Class B- 4, Class B-5 and Class B-6 Certificates,
               in each case up to an amount equal to and in the following order:
               (a) the Accrued Certificate Interest thereon for such
               Distribution Date, (b) any Accrued Certificate Interest thereon
               remaining undistributed from previous Distribution Dates and (c)
               such Class's Allocable Share for such Distribution Date, in each
               case, to the extent of remaining Available Funds.

               (D) On each Distribution Date prior to the Cross-Over Date, but
               after the reduction of the Current Principal Amount of the Group
               1 or Group 2 Senior Certificates to zero, the remaining Class or
               Classes of Senior Certificates will be entitled to receive in
               reduction of their Current Principal Amounts, pro rata based upon
               their Current Principal Amounts immediately prior to such
               Distribution Date, in addition to any Principal Prepayments
               related to such remaining Senior Certificates' respective Loan
               Group allocated to such Group of Senior Certificates, 100% of the
               Principal Prepayments on any Mortgage Loan in the Loan Group
               relating to the fully repaid Class of Senior Certificates;
               provided, however, that if (A) the weighted average Subordinate
               Percentage equals or exceeds 6.00% on such Distribution Date and
               (B) the aggregate Scheduled Principal Balance of the Mortgage
               Loans delinquent 60 days or more (including for this purpose any
               such Mortgage Loans in foreclosure and Mortgage Loans with
               respect to which the related Mortgaged Property has been acquired
               by the Trust), averaged over the last six months, as a percentage
               of the sum of the aggregate Current Principal Amount of the
               Subordinate Certificates does not exceed 100%, then the
               additional allocation of Principal Prepayments to the Senior
               Certificates in accordance with this clause (D) will not be made.

               (E) If on any Distribution Date on which the aggregate Current
               Principal Amount of any Class or Classes of Senior Certificates
               would be greater than the aggregate Scheduled Principal Balance
               of the Mortgage Loans in its related Loan Group and any
               Subordinate Certificates are still outstanding in each case after
               giving effect to distributions to be made on such Distribution
               Date, (i) 100% of amounts otherwise allocable to the Subordinate
               Certificates in respect of principal will be distributed to such
               Class or Classes of Senior Certificates in reduction of the
               Current Principal Amounts thereof, until the aggregate Current
               Principal Amount of such Class or Classes of Senior Certificates
               is an amount equal to the aggregate Scheduled Principal Balance
               of the Mortgage Loans in its related Loan Group, and (ii) the
               Accrued Certificate Interest otherwise allocable to the
               Subordinate Certificates on such Distribution Date will be
               reduced, if necessary, and distributed to such Class or Classes
               of Senior Certificates in an amount equal to the Accrued
               Certificate Interest for such Distribution Date on the excess of
               (x) the aggregate Current Principal Balance of such Class or
               Classes of Senior Certificates over (y) the aggregate Scheduled
               Principal Balance of the Mortgage Loans in the related Loan
               Group. Any such reduction in the Accrued Certificate Interest on
               the Subordinate Certificates will be allocated in reverse order
               of the Subordinate Certificates numerical designations,
               commencing with the Class B-6 Certificates.

        (c) If, after distributions have been made pursuant to priorities first
and second of clauses (a)(i)(A) and (B) above on any Distribution Date, the
remaining Group 1 or Group 2 Available Funds are less than the sum of the Group
1 or Group 2 Senior Optimal Principal Amounts such amount shall be reduced, and
such remaining funds will be distributed on the related Senior Certificates on
the basis of such reduced amount.

        (d) "Pro rata" distributions among Classes of Certificates will be made
in proportion to the then Current Principal Amount of such Classes.

        (e) On each Distribution Date, any Available Funds remaining after
payment of interest and principal to the Classes of Certificates entitled
thereto, as described above, will be distributed to the Class R-II Certificates;
provided that if on any Distribution Date there are any Group 1 or Group 2
Available Funds remaining after payment of interest and principal to a Class or
Classes of Certificates entitled thereto, such amounts will be distributed to
the other Classes of Senior Certificates, pro rata, based upon their Current
Principal Amounts, until all amounts due to all Classes of Senior Certificates
have been paid in full, before any amounts are distributed to the Class R-II
Certificates.

        (f) No Accrued Certificate Interest will be payable with respect to any
Class of Certificates after the Distribution Date on which the Current Principal
Amount of such Certificate has been reduced to zero.

        (g) If on any Distribution Date the Available Funds for the Senior
Certificates in any Certificate Group is less than the Accrued Certificate
Interest on the related Senior Certificates for such Distribution Date prior to
reduction for Net Interest Shortfall and the interest portion of Realized
Losses, the shortfall will be allocated among the holders of each Class of
Senior Certificates in such Certificate Group in proportion to the respective
amounts of Accrued Certificate Interest that would have been allocated thereto
in the absence of such Net Interest Shortfall and/or Realized Losses for such
Distribution Date. In addition, the amount of any interest shortfalls will
constitute unpaid Accrued Certificate Interest and will be distributable to
holders of the Certificates of the related Classes entitled to such amounts on
subsequent Distribution Dates, to the extent of the applicable Available Funds
after current interest distributions as required herein. Any such amounts so
carried forward will not bear interest. Shortfalls in interest payments will not
be offset by a reduction in the servicing compensation of the Master Servicer or
otherwise, except to the extent of applicable Compensating Interest Payments.

        (h) The expenses and fees of the Trust shall be paid by each of the
REMICs, to the extent that such expenses relate to the assets of each of such
respective REMICs, and all other expenses and fees of the Trust shall be paid
pro rata by each of the REMICs.

        Section 6.02 ALLOCATION OF LOSSES. (a) On or prior to each Determination
Date, the Master Servicer shall determine the amount of any Realized Loss in
respect of each Mortgage Loan that occurred during the immediately preceding
calendar month.

        (b) With respect to any Certificates on any Distribution Date, the
principal portion of each Realized Loss on a Mortgage Loan shall be allocated as
follows:

               first, to the Class B-6 Certificates until the Current Principal
        Amount thereof has been reduced to zero;

               second, to the Class B-5 Certificates until the Current Principal
        Amount thereof has been reduced to zero;

               third, to the Class B-4 Certificates until the Current Principal
        Amount thereof has been reduced to zero;

               fourth, to the Class B-3 Certificates until the Current Principal
        Amount thereof has been reduced to zero;

               fifth, to the Class B-2 Certificates until the Current Principal
        Amount thereof has been reduced to zero;

               sixth, to the Class B-1 Certificates until the Current Principal
        Amount thereof has been reduced to zero;

               seventh, if such loss is on a Group 1 or Group 2 Mortgage Loan,
        to the Group 1 or Group 2 Senior Certificates, respectively.

               eighth, to the Senior Certificates, on a pro rata basis.

        (c) Notwithstanding the foregoing clause (b), no such allocation of any
Realized Loss shall be made on a Distribution Date to any Class of Certificates
to the extent that such allocation would result in the reduction of the
aggregate Current Principal Amounts of all the Certificates as of such
Distribution Date, after giving effect to all distributions and prior
allocations of Realized Losses on such date, to an amount less than the
aggregate Scheduled Principal Balance of all of the Mortgage Loans as of the
first day of the month of such Distribution Date (such limitation, the "Loss
Allocation Limitation").

        (d) Any Realized Losses allocated to a Class of Certificates shall be
allocated among the Certificates of such Class in proportion to their respective
Current Principal Amounts. Any allocation of Realized Losses shall be
accomplished by reducing the Current Principal Amount of the related
Certificates on the related Distribution Date.

        (e) Realized Losses shall be allocated on the Distribution Date in the
month following the month in which such loss was incurred and, in the case of
the principal portion thereof, after giving effect to distributions made on such
Distribution Date.

                                      -66-

<PAGE>

        (f) On each Distribution Date, the Securities Administrator shall
determine and notify the Trustee of the Subordinate Certificate Writedown
Amount. Any such Subordinate Certificate Writedown Amount shall effect a
corresponding reduction in the Current Principal Amount of (i) if prior to the
Cross-Over Date, the Current Principal Amounts of the Subordinate Certificates,
in the reverse order of their numerical Class designations and (ii) from and
after the Cross-Over Date, the Senior Certificates which reduction shall occur
on such Distribution Date after giving effect to distributions made on such
Distribution Date.

        (g) Any Net Interest Shortfall will be allocated among the Classes of
Certificates in proportion to the respective amounts of Accrued Certificate
Interest that would have been allocated thereto in the absence of such Net
Interest Shortfall for such Distribution Date. The interest portion of any
Realized Losses with respect to the Mortgage Loans occurring on or prior to the
Cross-Over Date will not be allocated among any Certificates, but will reduce
the amount of Available Funds on the related Distribution Date. As a result of
the subordination of the Subordinate Certificates in right of distribution, such
Realized Losses will be borne by the Subordinate Certificates in inverse order
of their numerical Class designations. Following the Cross-Over Date, the
interest portion of Realized Losses on the Mortgage Loans in any Loan Group will
be allocated to the related Senior Certificates.

        Section 6.03 PAYMENTS. (a) On each Distribution Date, other than the
final Distribution Date, the Trustee shall distribute to each Certificateholder
of record on the directly preceding Record Date the Certificateholder's pro rata
share of its Class (based on the aggregate Fractional Undivided Interest
represented by such Holder's Certificates) of all amounts required to be
distributed on such Distribution Date to such Class, based on information
provided to the Securities Administrator by the Master Servicer. The Securities
Administrator shall calculate the amount to be distributed to each Class and,
based on such amounts, the Securities Administrator shall determine the amount
to be distributed to each Certificateholder. All of the Securities
Administrator's calculations of payments shall be based solely on information
provided to the Securities Administrator by the Master Servicer. The Securities
Administrator shall not be required to confirm, verify or recompute any such
information but shall be entitled to rely conclusively on such information.

        (b) Payment of the above amounts to each Certificateholder shall be made
(i) by check mailed to each Certificateholder entitled thereto at the address
appearing in the Certificate Register or (ii) upon receipt by the Trustee on or
before the fifth Business Day preceding the Record Date of written instructions
from a Certificateholder by wire transfer to a United States dollar account
maintained by the payee at any United States depository institution with
appropriate facilities for receiving such a wire transfer; provided, however,
that the final payment in respect of each Class of Certificates will be made
only upon presentation and surrender of such respective Certificates at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final payment.

        The Securities Administrator may make available each month, to any
interested party , the monthly statement to Certificateholders via the
Securities Administrator's website initially located at "www.ctslink.com."
Assistance in using the website can be obtained by calling the Securities
Administrator's customer service desk at (301) 815-6600. Parties that are unable
to use the above distribution option are entitled to have a paper copy mailed to
them via first class mail by calling the customer service desk and indicating
such. The Securities Administrator shall have the right to change the way such
reports are distributed in order to make such distribution more convenient
and/or more accessible to the parties, and the Securities Administrator shall
provide timely and adequate notification to all parties regarding any such
change.

        (b) By April 30 of each year beginning in 2003, the Trustee will furnish
such report to each Holder of the Certificates of record at any time during the
prior calendar year as to the aggregate of amounts reported pursuant to
subclauses (a)(ii) and (a)(v) above with respect to the Certificates, plus
information with respect to the amount of servicing compensation and such other
customary information as the Securities Administrator may determine and advises
the Trustee to be necessary and/or to be required by the Internal Revenue
Service or by a federal or state law or rules or regulations to enable such
Holders to prepare their tax returns for such calendar year. Such obligations
shall be deemed to have been satisfied to the extent that substantially
comparable information shall be provided by the Securities Administrator or the
Trustee pursuant to the requirements of the Code.

        Section 6.05 MONTHLY ADVANCES. If the Scheduled Payment on a Mortgage
Loan that was due on a related Due Date and is delinquent other than as a result
of application of the Relief Act and for which the related Servicer was required
to make an advance pursuant to the related Servicing Agreement exceeds the
amount deposited in the Master Servicer Collection Account which will be used
for an advance with respect to such Mortgage Loan, the Master Servicer will
deposit in the Master Servicer Collection Account not later than the
Distribution Account Deposit Date immediately preceding the related Distribution
Date an amount equal to such deficiency, net of the Servicing Fee for such
Mortgage Loan except to the extent the Master Servicer determines any such
advance to be nonrecoverable from Liquidation Proceeds, Insurance Proceeds or
future payments on the Mortgage Loan for which such Monthly Advance was made.
Subject to the foregoing, the Master Servicer shall continue to make such
advances through the date that the related Servicer is required to do so under
its Servicing Agreement. If applicable, on the Distribution Account Deposit
Date, the Master Servicer shall present an Officer's Certificate to the Trustee

Servicer shall not be entitled to any reimbursement of any Compensating Interest
Payment.

related to the Master Servicer's failure to perform its duties in compliance

legal action knowledge thereof. This indemnity shall survive the resignation or
removal of the Trustee, Master Servicer or the Securities Administrator and the
termination of this Agreement.

        (b) The Seller will indemnify any Indemnified Person for any loss,
liability or expense of any Indemnified Person not otherwise referred to in

Subject to the obligation of the Master Servicer to indemnify the Indemnified
Persons pursuant to Section 7.03:

        (a) Neither the Master Servicer nor any of the directors, officers,
employees or agents of the Master Servicer shall be under any liability to the
Indemnified Persons, the Seller, the Trust Fund or the Certificateholders for
taking any action or for refraining from taking any action in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Master Servicer or any such Person against
any breach of warranties or representations made herein or any liability which

faith or gross negligence in the performance of duties or by reason of reckless
disregard of obligations and duties hereunder.

any claim or legal action (including any pending or threatened claim or legal
action) relating to this Agreement, the Certificates or any Servicing Agreement
(except to the extent that the Master Servicer is indemnified by the Servicer

the Custodial Agreement, as applicable.

        (d) The Master Servicer shall not be under any obligation to appear in,
prosecute or defend any legal action that is not incidental to its duties under
this Agreement and that in its opinion may involve it in any expense or
liability; provided, however, the Master Servicer may in its discretion, with
the consent of the Trustee (which consent shall not be unreasonably withheld),
undertake any such action which it may deem necessary or desirable with respect
to this Agreement and the rights and duties of the parties hereto and the
interests of the Certificateholders hereunder. In such event, the legal expenses
and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Trust Fund, and the Master Servicer shall
be entitled to be reimbursed therefor out of the Master Servicer Collection
Account as provided by Section 4.03. Nothing in this Subsection 7.04(d) shall
affect the Master Servicer's obligation to supervise, or to take such actions as

        (f) The Master Servicer shall not be liable for any acts or omissions of
any Servicer, except as otherwise expressly provided herein.

        Section 7.05 MASTER SERVICER NOT TO RESIGN. Except as provided in
Section 7.07, the Master Servicer shall not resign from the obligations and
duties hereby imposed on it except upon a determination that any such duties
hereunder are no longer permissible under applicable law and such
impermissibility cannot be cured. Any such determination permitting the
resignation of the Master Servicer shall be evidenced by an Opinion of
Independent Counsel to such effect delivered to the Trustee. No such resignation
by the Master Servicer shall become effective until EMC or the Trustee or a
successor to the Master Servicer reasonably satisfactory to the Trustee shall
have assumed the responsibilities and obligations of the Master Servicer in
accordance with Section 8.02 hereof. The Trustee shall notify the Rating
Agencies of the resignation of the Master Servicer.

        Section 7.06 SUCCESSOR MASTER SERVICER. In connection with the
appointment of any successor Master Servicer or the assumption of the duties of
the Master Servicer, EMC or the Trustee may make such arrangements for the
compensation of such successor master servicer out of payments on the Mortgage

the successor master servicer does not agree that such market value is a fair
price, such successor master servicer shall obtain two quotations of market
value from third parties actively engaged in the servicing of single-family
mortgage loans.

        Section 7.07 SALE AND ASSIGNMENT OF MASTER SERVICING. The Master
Servicer may sell and assign its rights and delegate its duties and obligations

Trustee an agreement, in form and substance reasonably satisfactory to the
Trustee, which contains an assumption by such Person of the due and punctual
performance and observance of each covenant and condition to be performed or
observed by it as master servicer under this Agreement, any custodial agreement
from and after the effective date of such agreement; (ii) each Rating Agency
shall be given prior written notice of the identity of the proposed successor to
the Master Servicer and each Rating Agency's rating of the Certificates in
effect immediately prior to such assignment, sale and delegation will not be
downgraded, qualified or withdrawn as a result of such assignment, sale and
delegation, as evidenced by a letter to such effect delivered to the Master
Servicer and the Trustee; (iii) the Master Servicer assigning and selling the
master servicing shall deliver to the Trustee an Officer's Certificate and an

such action under this Agreement have been completed and such action is
permitted by and complies with the terms of this Agreement; and (iv) in the
event the Master Servicer is terminated without cause by EMC, EMC shall pay the
terminated Master Servicer a

termination fee equal to 0.25% of the aggregate Scheduled Principal Balance of
the Mortgage Loans at the time the master servicing of the Mortgage Loans is
transferred to the successor Master Servicer. No such assignment or delegation
shall affect any liability of the Master Servicer arising prior to the effective
date thereof.

                                  ARTICLE VIII

                                     Default

        Section 8.01 EVENTS OF DEFAULT. "Event of Default," wherever used
herein, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body) and
only with respect to the defaulting Master Servicer:

               (i) The Master Servicer fails to cause to be deposited in the
        Distribution Account any amount so required to be deposited pursuant to
        this Agreement, and such failure continues unremedied for a period of
        three Business Days after the date upon which written notice of such
        failure, requiring the same to be remedied, shall have been given to the
        Master Servicer; or

               (ii) The Master Servicer fails to observe or perform in any
        material respect any other material covenants and agreements set forth
        in this Agreement to be performed by it, which covenants and agreements
        materially affect the rights of Certificateholders, and such failure
        continues unremedied for a period of 60 days after the date on which
        written notice of such failure, properly requiring the same to be
        remedied, shall have been given to the Master Servicer by the Trustee or
        to the Master Servicer and the Trustee by the Holders of Certificates
        evidencing Fractional Undivided Interests aggregating not less than 25%
        of the Trust Fund; or

               (iii) There is entered against the Master Servicer a decree or
        order by a court or agency or supervisory authority having jurisdiction
        in the premises for the appointment of a conservator, receiver or
        liquidator in any insolvency, readjustment of debt, marshaling of assets
        and liabilities or similar proceedings, or for the winding up or
        liquidation of its affairs, and the continuance of any such decree or
        order is unstayed and in effect for a period of 60 consecutive days, or
        an involuntary case is commenced against the Master Servicer under any
        applicable insolvency or reorganization statute and the petition is not
        dismissed within 60 days after the commencement of the case; or

               (iv) The Master Servicer consents to the appointment of a
        conservator or receiver or liquidator in any insolvency, readjustment of
        debt, marshaling of assets and liabilities or similar proceedings of or
        relating to the Master Servicer or substantially all of its property; or
        the Master Servicer admits in writing its inability to pay its debts
        generally as they become due, files a petition to take advantage of any
        applicable insolvency or reorganization statute, makes an assignment for
        the benefit of its creditors, or voluntarily suspends payment of its
        obligations; or

               (v) The Master Servicer assigns or delegates its duties or rights
        under this Agreement in contravention of the provisions permitting such
        assignment or delegation under Sections 7.05 or 7.07.

                                      -75-

<PAGE>

In each and every such case, so long as such Event of Default with respect to
the Master Servicer shall not have been remedied, either the Trustee or the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% of the principal of the Trust Fund, by notice in writing to
the Master Servicer (and to the Trustee if given by such Certificateholders),
with a copy to the Rating Agencies, and with the consent of EMC, may terminate
all of the rights and obligations (but not the liabilities) of the Master
Servicer under this Agreement and in and to the Mortgage Loans and/or the REO
Property serviced by the Master Servicer and the proceeds thereof. Upon the
receipt by the Master Servicer of the written notice, all authority and power of
the Master Servicer under this Agreement, whether with respect to the
Certificates, the Mortgage Loans, REO Property or under any other related
agreements (but only to the extent that such other agreements relate to the
Mortgage Loans or related REO Property) shall, subject to Section 8.02,
automatically and without further action pass to and be vested in the Trustee
pursuant to this Section 8.01; and, without limitation, the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of the Master
Servicer as attorney-in-fact or otherwise, any and all documents and other
instruments and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. The Master Servicer agrees to cooperate with
the Trustee in effecting the termination of the Master Servicer's rights and
obligations hereunder, including, without limitation, the transfer to the
Trustee of (i) the property and amounts which are then or should be part of the
Trust or which thereafter become part of the Trust; and (ii) originals or copies
of all documents of the Master Servicer reasonably requested by the Trustee to
enable it to assume the Master Servicer's duties thereunder. In addition to any
other amounts which are then, or, notwithstanding the termination of its
activities under this Agreement, may become payable to the Master Servicer under
this Agreement, the Master Servicer shall be entitled to receive, out of any
amount received on account of a Mortgage Loan or related REO Property, that
portion of such payments which it would have received as reimbursement under
this Agreement if notice of termination had not been given. The termination of
the rights and obligations of the Master Servicer shall not affect any
obligations incurred by the Master Servicer prior to such termination.

        Section 8.02 TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR. (a) Upon the
receipt by the Master Servicer of a notice of termination pursuant to Section
8.01 or an Opinion of Independent Counsel pursuant to Section 7.05 to the effect
that the Master Servicer is legally unable to act or to delegate its duties to a
Person which is legally able to act, the Trustee shall automatically become the
successor in all respects to the Master Servicer in its capacity under this
Agreement and the transactions set forth or provided for herein and shall
thereafter be subject to all the responsibilities, duties, liabilities and
limitations on liabilities relating thereto placed on the Master Servicer by the
terms and provisions hereof; provided, however, that EMC shall have the right to
either (a) immediately assume the duties of the Master Servicer or (b) select a
successor Master Servicer; provided further, however, that the Trustee shall
have no obligation whatsoever with respect to any liability (other than advances
deemed recoverable and not previously made) incurred by the Master Servicer at
or prior to the time of termination. As compensation therefor, but subject to
Section 7.06, the Trustee shall be entitled to all funds relating to the
Mortgage Loans which the Master Servicer would have been entitled to retain if
the Master Servicer had continued to act hereunder, except for those amounts due
the Master Servicer as reimbursement permitted under this Agreement for advances
previously made or expenses previously incurred. Notwithstanding the above, the
Trustee may, if it shall be unwilling so to act, or shall, if it is legally
unable so to act, appoint or petition a

                                      -76-

<PAGE>

court of competent jurisdiction to appoint, any established housing and home
finance institution which is a Fannie Mae- or Freddie Mac-approved servicer, and
with respect to a successor to the Master Servicer only, having a net worth of
not less than $10,000,000, as the successor to the Master Servicer hereunder in
the assumption of all or any part of the responsibilities, duties or liabilities
of the Master Servicer hereunder; provided, that the Trustee shall obtain a
letter from each Rating Agency that the ratings, if any, on each of the
Certificates will not be lowered as a result of the selection of the successor
to the Master Servicer. Pending appointment of a successor to the Master
Servicer hereunder, the Trustee shall act in such capacity as hereinabove
provided. In connection with such appointment and assumption, the Trustee may
make such arrangements for the compensation of such successor out of payments on
the Mortgage Loans as it and such successor shall agree; provided, however, that
the provisions of Section 7.06 shall apply, no such compensation shall be in
excess of that permitted the Trustee under this Subsection 8.02(a), and that
such successor shall undertake and assume the obligations of the Trustee to pay
compensation to any third Person acting as an agent or independent contractor in
the performance of master servicing responsibilities hereunder. The Trustee and
such successor shall take such action, consistent with this Agreement, as shall
be necessary to effectuate any such succession.

        (b) If the Trustee shall succeed to any duties of the Master Servicer
respecting the Mortgage Loans as provided herein, it shall do so in a separate
capacity and not in its capacity as Trustee and, accordingly, the provisions of
Article IX shall be inapplicable to the Trustee in its duties as the successor
to the Master Servicer in the servicing of the Mortgage Loans (although such
provisions shall continue to apply to the Trustee in its capacity as Trustee);
the provisions of Article VII, however, shall apply to it in its capacity as
successor master servicer.

        Section 8.03 NOTIFICATION TO CERTIFICATEHOLDERS. Upon any termination or
appointment of a successor to the Master Servicer, the Trustee shall give prompt
written notice thereof to Certificateholders at their respective addresses
appearing in the Certificate Register and to the Rating Agencies.

        Section 8.04 WAIVER OF DEFAULTS. The Trustee shall transmit by mail to
all Certificateholders, within 60 days after the occurrence of any Event of
Default known to the Trustee, unless such Event of Default shall have been
cured, notice of each such Event of Default hereunder known to the Trustee. The
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% of the Trust Fund may, on behalf of all Certificateholders,
waive any default by the Master Servicer in the performance of its obligations
hereunder and the consequences thereof, except a default in the making of or the
causing to be made any required distribution on the Certificates. Upon any such
waiver of a past default, such default shall be deemed to cease to exist, and
any Event of Default arising therefrom shall be deemed to have been timely
remedied for every purpose of this Agreement. No such waiver shall extend to any
subsequent or other default or impair any right consequent thereon except to the
extent expressly so waived. The Trustee shall give notice of any such waiver to
the Rating Agencies.

        Section 8.05 LIST OF CERTIFICATEHOLDERS. Upon written request of three
or more Certificateholders of record, for purposes of communicating with other
Certificateholders with respect to their rights under this Agreement, the
Trustee will afford such Certificateholders access during business hours to the
most recent list of Certificateholders held by the Trustee.

                                   ARTICLE IX

                      Concerning the Trustee and the Securities Administrator

        Section 9.01 DUTIES OF TRUSTEE. (a) The Trustee, prior to the occurrence
of an Event of Default and after the curing or waiver of all Events of Default
which may have occurred, and the Securities Administrator each undertake to
perform such duties and only such duties as are specifically set forth in this
Agreement as duties of the Trustee and the Securities Administrator,
respectively. If an Event of Default has occurred and has not been cured or
waived, the Trustee shall exercise such of the rights and powers vested in it by
this Agreement, and subject to Section 8.02(b) use the same degree of care and
skill in their exercise, as a prudent person would exercise under the
circumstances in the conduct of his own affairs.

        (b) Upon receipt of all resolutions, certificates, statements, opinions,
reports, documents, orders or other instruments which are specifically required
to be furnished to the Trustee and the Securities Administrator pursuant to any
provision of this Agreement, the Trustee and the Securities Administrator,
respectively, shall examine them to determine whether they are in the form
required by this Agreement; provided, however, that neither the Trustee nor the
Securities Administrator shall be responsible for the accuracy or content of any
resolution, certificate, statement, opinion, report, document, order or other
instrument furnished by the Master Servicer; provided, further, that neither the
Trustee nor the Securities Administrator shall be responsible for the accuracy
or verification of any calculation provided to it pursuant to this Agreement.

        (c) On each Distribution Date, the Trustee shall make monthly
distributions and the final distribution to the Certificateholders from funds in
the Distribution Account as provided in Sections 6.01 and 10.01 herein based the
report of the Securities Administrator.

        (d) No provision of this Agreement shall be construed to relieve the
Trustee or the Securities Administrator from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct;
provided, however, that:

               (i) Prior to the occurrence of an Event of Default, and after the
        curing or waiver of all such Events of Default which may have occurred,
        the duties and obligations of the Trustee and the Securities
        Administrator shall be determined solely by the express provisions of
        this Agreement, neither the Trustee nor the Securities Administrator
        shall be liable except for the performance of their respective duties
        and obligations as are specifically set forth in this Agreement, no
        implied covenants or obligations shall be read into this Agreement
        against the Trustee or the Securities Administrator and, in the absence
        of bad faith on the part of the Trustee or the Securities Administrator,
        respectively, the Trustee or the Securities Administrator, respectively,
        may conclusively rely, as to the truth of the statements and the
        correctness of the opinions expressed therein, upon any certificates or
        opinions furnished to the Trustee or the Securities Administrator,
        respectively, and conforming to the requirements of this Agreement;

               (ii) Neither the Trustee nor the Securities Administrator shall
        be liable in its individual capacity for an error of judgment made in
        good faith by a Responsible Officer or

                                      -79-

<PAGE>

        Responsible Officers of the Trustee or an officer of the Securities
        Administrator, respectively, unless it shall be proved that the Trustee
        or the Securities Administrator, respectively, was negligent in
        ascertaining the pertinent facts;

               (iii) Neither the Trustee nor the Securities Administrator shall
        be liable with respect to any action taken, suffered or omitted to be
        taken by it in good faith in accordance with the directions of the
        Holders of Certificates evidencing Fractional Undivided Interests
        aggregating not less than 25% of the Trust Fund, if such action or
        non-action relates to the time, method and place of conducting any
        proceeding for any remedy available to the Trustee or the Securities
        Administrator, respectively, or exercising any trust or other power
        conferred upon the Trustee or the Securities Administrator,
        respectively, under this Agreement;

               (iv) The Trustee shall not be required to take notice or be
        deemed to have notice or knowledge of any default or Event of Default
        unless a Responsible Officer of the Trustee's Corporate Trust Office
        shall have actual knowledge thereof. In the absence of such notice, the
        Trustee may conclusively assume there is no such default or Event of
        Default;

               (v) The Trustee shall not in any way be liable by reason of any
        insufficiency in any Account held by or in the name of Trustee unless it
        is determined by a court of competent jurisdiction that the Trustee's
        gross negligence or willful misconduct was the primary cause of such
        insufficiency (except to the extent that the Trustee is obligor and has
        defaulted thereon);

               (vi) Anything in this Agreement to the contrary notwithstanding,
        in no event shall the Trustee or the Securities Administrator be liable
        for special, indirect or consequential loss or damage of any kind
        whatsoever (including but not limited to lost profits), even if the
        Trustee or the Securities Administrator, respectively, has been advised
        of the likelihood of such loss or damage and regardless of the form of
        action; and

               (vii) None of the Securities Administrator, EMC or the Trustee
        shall be responsible for the acts or omissions of the other, it being
        understood that this Agreement shall not be construed to render them
        partners, joint venturers or agents of one another.

        Neither the Trustee nor the Securities Administrator shall be required
to expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if there is reasonable ground for believing that the repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it, and none of the provisions contained in this Agreement
shall in any event require the Trustee or the Securities Administrator to
perform, or be responsible for the manner of performance of, any of the
obligations of the Master Servicer under the Servicing Agreements, except during
such time, if any, as the Trustee shall be the successor to, and be vested with
the rights, duties, powers and privileges of, the Master Servicer in accordance
with the terms of this Agreement.

        (e) All funds received by the Master Servicer and the Trustee and
required to be deposited in the Master Servicer Collection Account or
Distribution Account pursuant to this Agreement will be promptly so deposited by
the Master Servicer and the Trustee.

                                      -80-

<PAGE>

        (f) Except for those actions that the Trustee or the Securities
Administrator is required to take hereunder, neither the Trustee nor the
Securities Administrator shall have any obligation or liability to take any
action or to refrain from taking any action hereunder in the absence of written
direction as provided hereunder.

        Section 9.02   CERTAIN MATTERS AFFECTING THE TRUSTEE AND THE SECURITIES
ADMINISTRATOR. Except as otherwise provided in Section 9.01:

               (i) The Trustee and the Securities Administrator may rely and
        shall be protected in acting or refraining from acting in reliance on
        any resolution, certificate of a Seller, Master Servicer or Servicer,
        certificate of auditors or any other certificate, statement, instrument,
        opinion, report, notice, request, consent, order, appraisal, bond or
        other paper or document believed by it to be genuine and to have been
        signed or presented by the proper party or parties;

               (ii) The Trustee and the Securities Administrator may consult
        with counsel and any advice of such counsel or any Opinion of Counsel
        shall be full and complete authorization and protection with respect to
        any action taken or suffered or omitted by it hereunder in good faith
        and in accordance with such advice or Opinion of Counsel:

               (iii) Neither the Trustee nor the Securities Administrator shall
        be under any obligation to exercise any of the trusts or powers vested
        in it by this Agreement, other than its obligation to give notices
        pursuant to this Agreement, or to institute, conduct or defend any
        litigation hereunder or in relation hereto at the request, order or
        direction of any of the Certificateholders pursuant to the provisions of
        this Agreement, unless such Certificateholders shall have offered to the
        Trustee reasonable security or indemnity against the costs, expenses and
        liabilities which may be incurred therein or thereby. Nothing contained
        herein shall, however, relieve the Trustee of the obligation, upon the
        occurrence of an Event of Default of which a Responsible Officer of the
        Trustee's Corporate Trust Office has actual knowledge (which has not
        been cured or waived), subject to Section 8.02(b), to exercise such of
        the rights and powers vested in it by this Agreement, and to use the
        same degree of care and skill in their exercise, as a prudent person
        would exercise under the circumstances in the conduct of his own
        affairs;

               (iv) Prior to the occurrence of an Event of Default hereunder and
        after the curing or waiver of all Events of Default which may have
        occurred, neither the Trustee nor the Securities Administrator shall be
        liable in its individual capacity for any action taken, suffered or
        omitted by it in good faith and believed by it to be authorized or
        within the discretion or rights or powers conferred upon it by this
        Agreement;

               (v) Neither the Trustee nor the Securities Administrator shall be
        bound to make any investigation into the facts or matters stated in any
        resolution, certificate, statement, instrument, opinion, report, notice,
        request, consent, order, approval, bond or other paper or document,
        unless requested in writing to do so by Holders of Certificates
        evidencing Fractional Undivided Interests aggregating not less than 25%
        of the Trust Fund and provided

                                      -81-

<PAGE>

        that the payment within a reasonable time to the Trustee or the
        Securities Administrator, as applicable, of the costs, expenses or
        liabilities likely to be incurred by it in the making of such
        investigation is, in the opinion of the Trustee or the Securities
        Administrator, as applicable, reasonably assured to the Trustee or the
        Securities Administrator, as applicable, by the security afforded to it
        by the terms of this Agreement. The Trustee or the Securities
        Administrator may require reasonable indemnity against such expense or
        liability as a condition to taking any such action. The reasonable
        expense of every such examination shall be paid by the
        Certificateholders requesting the investigation;

               (vi) The Trustee and the Securities Administrator may execute any
        of the trusts or powers hereunder or perform any duties hereunder either
        directly or through Affiliates, agents or attorneys; provided, however,
        that the Trustee may not appoint any agent to perform its custodial
        functions with respect to the Mortgage Files or paying agent functions
        under this Agreement without the express written consent of the Master
        Servicer, which consent will not be unreasonably withheld. Neither the
        Trustee nor the Securities Administrator shall be liable or responsible
        for the misconduct or negligence of any of the Trustee's or the
        Securities Administrator's agents or attorneys or a custodian or paying
        agent appointed hereunder by the Trustee or the Securities Administrator
        with due care and, when required, with the consent of the Master
        Servicer;

               (vii) Should the Trustee or the Securities Administrator deem the
        nature of any action required on its part, other than a payment or
        transfer under Subsection 4.01(b) or Section 4.02, to be unclear, the
        Trustee or the Securities Administrator, respectively, may require prior
        to such action that it be provided by the Seller with reasonable further
        instructions;

               (viii) The right of the Trustee or the Securities Administrator
        to perform any discretionary act enumerated in this Agreement shall not
        be construed as a duty, and neither the Trustee nor the Securities
        Administrator shall be accountable for other than its negligence or
        willful misconduct in the performance of any such act;

               (ix) Neither the Trustee nor the Securities Administrator shall
        be required to give any bond or surety with respect to the execution of
        the trust created hereby or the powers granted hereunder, except as
        provided in Subsection 9.07; and

               (x) Neither the Trustee nor the Securities Administrator shall
        have any duty to conduct any affirmative investigation as to the
        occurrence of any condition requiring the repurchase of any Mortgage
        Loan by the Mortgage Loan Seller pursuant to this Agreement or the
        Mortgage Loan Purchase Agreement, as applicable, or the eligibility of
        any Mortgage Loan for purposes of this Agreement.

        Section 9.03 TRUSTEE AND SECURITIES ADMINISTRATOR NOT LIABLE FOR
CERTIFICATES OR MORTGAGE LOANS. The recitals contained herein and in the
Certificates (other than the signature and countersignature of the Trustee on
the Certificates) shall be taken as the statements of the Seller, and neither
the Trustee nor the Securities Administrator shall have any responsibility for
their correctness. Neither the Trustee nor the Securities Administrator makes
any representation as to the validity or sufficiency of the Certificates (other
than the signature and countersignature of the Trustee on the Certificates) or
of any Mortgage Loan except as expressly provided in Sections 2.02 and 2.05
hereof; provided, however, that the foregoing shall not relieve the Trustee of
the obligation to review the Mortgage Files pursuant to Sections 2.02 and 2.04.
The Trustee's signature and countersignature (or countersignature of its agent)
on the Certificates shall be solely in its capacity as Trustee and shall not
constitute the Certificates an obligation of the Trustee in any other capacity.
Neither the Trustee or the Securities Administrator shall be accountable for the
use or application by the Seller of any of the Certificates or of the proceeds
of such Certificates, or for the use or application of any funds paid to the
Seller with respect to the Mortgage Loans. Subject to the provisions of Section
2.05, neither the Trustee nor the Securities Administrator shall not be
responsible for the legality or validity of this Agreement or any document or
instrument relating to this Agreement, the validity of the execution of this
Agreement or of any supplement hereto or instrument of further assurance, or the
validity, priority, perfection or sufficiency of the security for the
Certificates issued hereunder or intended to be issued hereunder. Neither the
Trustee nor the Securities Administrator shall at any time have any
responsibility or liability for or with respect to the legality, validity and
enforceability of any Mortgage or any Mortgage Loan, or the perfection and
priority of any Mortgage or the maintenance of any such perfection and priority,
or for or with respect to the sufficiency of the Trust Fund or its ability to
generate the payments to be distributed to Certificateholders, under this
Agreement. Neither the Trustee nor the Securities Administrator shall have any
responsibility for filing any financing or continuation statement in any public
office at any time or to otherwise perfect or maintain the perfection of any
security interest or lien granted to it hereunder or to record this Agreement
other than any continuation statements filed by the Trustee pursuant to Section
3.20.

        Section 9.04 TRUSTEE AND SECURITIES ADMINISTRATOR MAY OWN CERTIFICATES.
The Trustee and the Securities Administrator in its individual capacity or in
any capacity other than as Trustee hereunder may become the owner or pledgee of
any Certificates with the same rights it would have if it were not Trustee or
the Securities Administrator, as applicable, and may otherwise deal with the
parties hereto.

banking association organized and doing business under the laws of such state or
the United States of America, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus and undivided profits of at
least $40,000,000 or, in the case of a successor Trustee, $50,000,000, subject

the Trustee, rated "BBB" or higher by S&P with respect to their long-term rating

of the aforesaid supervising or examining authority, then for the purposes of
this Section 9.06 the combined capital and surplus of such corporation shall be

If no successor Trustee or Securities Administrator shall have been so appointed
and have accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee or Securities Administrator may petition any
court of competent jurisdiction for the appointment of a successor Trustee or
Securities Administrator.

Securities Administrator is removed), and the Trustee or Securities
Administrator so removed and the successor so appointed.

        (d) No resignation or removal of the Trustee or the Securities

        Section 9.09 SUCCESSOR TRUSTEE AND SUCCESSOR SECURITIES ADMINISTRATOR.
(a) Any successor Trustee or Securities Administrator appointed as provided in
Section 9.08 shall execute, acknowledge and deliver to the Seller and to its
predecessor Trustee or Securities Administrator an instrument accepting such
appointment hereunder. The resignation or removal of the predecessor Trustee or
Securities Administrator shall then become effective and such successor Trustee
or Securities Administrator, without any further act, deed or conveyance, shall
become fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as Trustee or
Securities Administrator herein. The predecessor Trustee or Securities

required for more fully and certainly vesting and confirming in the successor
Trustee or Securities Administrator, as applicable, all such rights, powers,
duties and obligations.

Administrator as provided in this Section 9.09, the successor Trustee or

        Section 9.10 MERGER OR CONSOLIDATION OF TRUSTEE OR SECURITIES
ADMINISTRATOR. Any state bank or trust company or national banking association
into which the Trustee or the Securities Administrator may be merged or
converted or with which it may be consolidated or any state bank or trust
company or national banking association resulting from any merger, conversion or
consolidation to which the Trustee or the Securities Administrator,
respectively, shall be a party, or any state bank or trust company or national
banking association succeeding to all or substantially all of the corporate
trust business of the Trustee or the Securities Administrator, respectively,
shall be the successor of the Trustee or the Securities Administrator,
respectively, hereunder, provided such state bank or trust company or national
banking association shall be eligible under the provisions of Section 9.06. Such
succession shall be valid without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding.

        Section 9.11 APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE. (a)
Notwithstanding any other provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any part of the
Trust or property constituting the same may at the time be located, the Seller
and the Trustee acting jointly shall have the power and shall execute and
deliver all instruments to appoint one or more Persons approved by the Trustee
and the Seller to act as cotrustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust, and to
vest in such Person or Persons, in such capacity, such title to the Trust, or
any part thereof, and, subject to the other provisions of this Section 9.11,
such powers, duties, obligations, rights and trusts as the Seller and the
Trustee may consider necessary or desirable.

        (b) If the Seller shall not have joined in such appointment within 15
days after the receipt by it of a written request so to do, the Trustee shall
have the power to make such appointment without the Seller.

        (c) No co-trustee or separate trustee hereunder shall be required to
meet the terms of eligibility as a successor Trustee under Section 9.06
hereunder and no notice to Certificateholders of the appointment of
co-trustee(s) or separate trustee(s) shall be required under Section 9.08
hereof.

        (d) In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 9.11, all rights, powers, duties and obligations
conferred or imposed upon the Trustee and required to be conferred on such
co-trustee shall be conferred or imposed upon and exercised or performed by the
Trustee and such separate trustee or co-trustee jointly, except to the extent
that under any law of any jurisdiction in which any particular act or acts are
to be performed (whether as Trustee hereunder or as successor to the Master
Servicer hereunder), the Trustee shall be incompetent or unqualified to perform
such act or acts, in which event such rights, powers, duties and obligations
(including the holding of title to the Trust or any portion thereof in any such
jurisdiction) shall be exercised and performed by such separate trustee or
co-trustee at the direction of the Trustee.

                                      -86-

<PAGE>

        (e) Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article IX. Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Trustee or separately, as
may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee.

        (f) To the extent not prohibited by law, any separate trustee or
co-trustee may, at any time, request the Trustee, its agent or attorney-in-fact,
with full power and authority, to do any lawful act under or with respect to
this Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties rights, remedies and trusts shall vest in and be
exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor Trustee.

        (g) No trustee under this Agreement shall be personally liable by reason
of any act or omission of another trustee under this Agreement. The Seller and
the Trustee acting jointly may at any time accept the resignation of or remove
any separate trustee or co-trustee.

        Section 9.12 FEDERAL INFORMATION RETURNS AND REPORTS TO
CERTIFICATEHOLDERS; REMIC ADMINISTRATION. (a) For federal income tax purposes,
the taxable year of each of REMIC I and REMIC II shall be a calendar year and
the Securities Administrator shall maintain or cause the maintenance of the
books of each such REMIC on the accrual method of accounting.

        (b) The Securities Administrator shall prepare and file or cause to be
filed with the Internal Revenue Service, and the Trustee shall sign, Federal tax
information returns or elections required to be made hereunder with respect to
each of REMIC I and REMIC II, the Trust Fund, if applicable, and the
Certificates containing such information and at the times and in the manner as
may be required by the Code or applicable Treasury regulations, and shall
furnish to each Holder of Certificates at any time during the calendar year for
which such returns or reports are made such statements or information at the
times and in the manner as may be required thereby, including, without
limitation, reports relating to interest, original issue discount and market
discount or premium (using a constant prepayment assumption of 25% CPR). The
Securities Administrator will apply for an Employee Identification Number from
the IRS under Form SS-4 or any other acceptable method for all tax entities. In
connection with the foregoing, the Securities Administrator shall timely prepare
and file, and the Trustee shall sign, IRS Form 8811, which shall provide the
name and address of the person who can be contacted to obtain information
required to be reported to the holders of regular interests in each of REMIC I
and REMIC II (the "REMIC Reporting Agent"). The Trustee shall make elections to
treat each of REMIC I and REMIC II as a REMIC (which elections shall apply to
the taxable period ending December 31, 2002 and each calendar year thereafter)
in such manner as the Code or applicable Treasury regulations may prescribe, and
as described by the Securities Administrator. The Trustee shall sign all tax
information returns filed pursuant to this Section and any other returns as may
be required by the Code. The Holder of the Class R-I

                                      -87-

<PAGE>

Certificate is hereby designated as the "Tax Matters Person" (within the meaning
of Treas. Reg. ss.ss.1.860F-4(d)) for REMIC I, and the Holder of the Class R-II
Certificate is hereby designated as the "Tax Matters Person" for REMIC II. The
Securities Administrator is hereby designated and appointed as the agent of each
such Tax Matters Person. Any Holder of a Residual Certificate will by acceptance
thereof appoint the Securities Administrator as agent and attorney-in-fact for
the purpose of acting as Tax Matters Person for each of REMIC I and REMIC II
during such time as the Securities Administrator does not own any such Residual
Certificate. In the event that the Code or applicable Treasury regulations
prohibit the Trustee from signing tax or information returns or other
statements, or the Securities Administrator from acting as agent for the Tax
Matters Person, the Trustee and the Securities Administrator shall take whatever
action that in its sole good faith judgment is necessary for the proper filing
of such information returns or for the provision of a tax matters person,
including designation of the Holder of a Residual Certificate to sign such
returns or act as tax matters person. Each Holder of a Residual Certificate
shall be bound by this Section.

        (c) The Securities Administrator shall provide upon request and receipt
of reasonable compensation, such information as required in Section
860D(a)(6)(B) of the Code to the Internal Revenue Service, to any Person
purporting to transfer a Residual Certificate to a Person other than a
transferee permitted by Section 5.05(b), and to any regulated investment
company, real estate investment trust, common trust fund, partnership, trust,
estate, organization described in Section 1381 of the Code, or nominee holding
an interest in a pass-through entity described in Section 860E(e)(6) of the
Code, any record holder of which is not a transferee permitted by Section
5.05(b) (or which is deemed by statute to be an entity with a disqualified
member).

        (d) The Securities Administrator shall prepare and file or cause to be
filed, and the Trustee shall sign, any state income tax returns required under
Applicable State Law with respect to each of REMIC I and REMIC II or the Trust
Fund.

        (e) Notwithstanding any other provision of this Agreement, the Trustee
and the Securities Administrator shall comply with all federal withholding
requirements respecting payments to Certificateholders of interest or original
issue discount on the Mortgage Loans, that the Trustee or the Securities
Administrator reasonably believes are applicable under the Code. The consent of
Certificateholders shall not be required for such withholding. In the event the
Trustee or the Securities Administrator withholds any amount from interest or
original issue discount payments or advances thereof to any Certificateholder
pursuant to federal withholding requirements, the Trustee or the Securities
Administrator shall, together with its monthly report to such
Certificateholders, indicate such amount withheld.

        (f) The Trustee and the Securities Administrator agree to indemnify the
Trust Fund and the Seller for any taxes and costs including, without limitation,
any reasonable attorneys fees imposed on or incurred by the Trust Fund, the
Seller or the Master Servicer, as a result of a breach of the Trustee's
covenants and the Securities Administrator's covenants, respectively, set forth
in this Section 9.12; provided, however, such liability and obligation to
indemnify in this paragraph shall not be joint and several and neither the
Trustee nor the Securities Administrator shall be liable or be obligated to
indemnify the Trust Fund for the failure by the other to perform any duty under
this Agreement or the breach by the other of any covenant in this Agreement.

                                   Termination

        Section 10.01 TERMINATION UPON REPURCHASE BY THE SELLER OR ITS DESIGNEE
OR LIQUIDATION OF THE MORTGAGE LOANS.

        (a) Subject to Section 10.02, the respective obligations and
responsibilities of the Seller, the Trustee, the Master Servicer and the
Securities Administrator created hereby, other than the obligation of the
Trustee to make payments to Certificateholders as hereinafter set forth shall
terminate upon:

               (i) the repurchase by or at the direction of the Seller or its
        designee of all Mortgage Loans and all related REO Property remaining in
        the Trust at a price equal to (a) 100% of the Outstanding Principal
        Balance of each Mortgage Loan (other than a Mortgage Loan related to REO
        Property) as of the date of repurchase, net of the principal portion of
        any unreimbursed Monthly Advances made by the purchaser, together with
        interest at the applicable Mortgage Interest Rate accrued but unpaid to,
        but not including, the first day of the month of repurchase, plus (b)
        the appraised value of any related REO Property, less the good faith
        estimate of the Seller of liquidation expenses to be incurred in
        connection with its disposal thereof (but not more than the Outstanding
        Principal Balance of the related Mortgage Loan, together with interest
        at the applicable Mortgage Interest Rate accrued on that balance but
        unpaid to, but not including, the first day of the month of repurchase),
        such appraisal to be calculated by an appraiser mutually agreed upon by
        the Seller and the Trustee at the expense of the Seller; or

               (ii) the later of the making of the final payment or other
        liquidation, or any advance with respect thereto, of the last Mortgage
        Loan remaining in the Trust Fund or the disposition of all property
        acquired with respect to any Mortgage Loan; provided, however, that in
        the event that an advance has been made, but not yet recovered, at the
        time of such termination, the Person having made such advance shall be
        entitled to receive, notwithstanding such termination, any payments
        received subsequent thereto with respect to which such advance was made;
        or

               (iii) the payment to Certificateholders of all amounts required
        to be paid to them pursuant to this Agreement.

        (b) In no event, however, shall the Trust created hereby continue beyond
the expiration of 21 years from the death of the last survivor of the
descendants of Joseph P. Kennedy, the late Ambassador of the United States to
the Court of St. James's, living on the date of this Agreement.

        (c) The right of the Seller or its designee to repurchase all the
Mortgage Loans pursuant to Subsection 10.01(a)(i) above shall be exercisable
only if (i) the aggregate Scheduled Principal Balance of the Mortgage Loans at
the time of any such repurchase is less than 10% of the Cut-off Date Balance or
(ii) the Seller, based upon an Opinion of Counsel, has determined that the REMIC
status of the REMIC I or REMIC II has been lost or that a substantial risk
exists that such REMIC

                                      -89-

<PAGE>

status will be lost for the then-current taxable year. At any time thereafter,
in the case of (i) or (ii) above, the Seller may elect to terminate the REMIC I
or REMIC II at any time, and upon such election, the Seller or its designee,
shall repurchase all the Mortgage Loans.

        (d) The Trustee shall give notice of any termination to the
Certificateholders, with a copy to the Master Servicer, the Securities
Administrator and the Rating Agencies, upon which the Certificateholders shall
surrender their Certificates to the Trustee for payment of the final
distribution and cancellation. Such notice shall be given by letter, mailed not
earlier than the l5th day and not later than the 25th day of the month next
preceding the month of such final distribution, and shall specify (i) the
Distribution Date upon which final payment of the Certificates will be made upon
presentation and surrender of the Certificates at the office of the Trustee
therein designated, (ii) the amount of any such final payment and (iii) that the
Record Date otherwise applicable to such Distribution Date is not applicable,
payments being made only upon presentation and surrender of the Certificates at
the office of the Trustee therein specified.

        (e) If the option of the Seller to repurchase or cause the repurchase of
all the Mortgage Loans under Subsection 10.01 (a)(i) above is exercised, the
Seller and/or its designee shall deliver to the Trustee for deposit in the
Distribution Account, by the Business Day prior to the applicable Distribution
Date, an amount equal to the repurchase price for the Mortgage Loans being
purchased by it and all property acquired with respect to such Mortgage Loans
remaining in REMIC I and REMIC II. Upon presentation and surrender of the
Certificates by the Certificateholders, the Trustee shall distribute to the
Certificateholders an amount determined as follows: with respect to each
Certificate (other than the Class R Certificates), the outstanding Current
Principal Amount, plus with respect to each Certificate (other than the Class R
Certificates), one month's interest thereon at the applicable Pass-Through Rate;
and with respect to the Class R Certificates, the percentage interest evidenced
thereby multiplied by the difference, if any, between the above described
repurchase price and the aggregate amount to be distributed to the Holders of
the Certificates (other than the Class R Certificates). If the proceeds with
respect to the Group 1 Mortgage Loans are not sufficient to pay all of the Group
1 Certificates in full, any such deficiency will be allocated first, to the
Subordinate Certificates, in inverse order of their numerical designation, and
then to the Group 1 Senior Certificates on a pro rata basis. If the proceeds
with respect to the Group 2 Mortgage Loans are not sufficient to pay all of the
Group 2 Certificates in full, any such deficiency will be allocated first, to
the Subordinate Certificates, in inverse order of their numerical designation,
and then to the Group 2 Senior Certificates on a pro rata basis. Upon deposit of
the required repurchase price and following such final Distribution Date, the
Trustee shall release promptly to the Seller and/or its designee the Mortgage
Files for the remaining applicable Mortgage Loans, and the Accounts with respect
thereto shall terminate, subject to the Trustee's obligation to hold any amounts
payable to Certificateholders in trust without interest pending final
distributions pursuant to Subsection 10.01(g). Any other amounts remaining in
the Accounts will belong to the Seller. Upon deposit of the required repurchase
price and following such final Distribution Date, the Trustee shall release
promptly to the Seller and/or its designee, as the case may be, the Mortgage
Files for the remaining Mortgage Loans, and the Accounts with respect thereto
shall terminate, subject to the Trustee's obligation to hold any amounts payable
to Certificateholders in trust without interest pending final distributions
pursuant to Subsection 10.01(g).

                                      -90-

<PAGE>

        (f) In the event that this Agreement is terminated by reason of the
payment or liquidation of all Mortgage Loans or the disposition of all property
acquired with respect to all Mortgage Loans under Subsection 10.01(a)(ii) above,
the Master Servicer shall deliver to the Trustee for deposit in the Distribution
Account all distributable amounts remaining in the Master Servicer Collection
Account. Upon the presentation and surrender of the Certificates, the Trustee
shall distribute to the remaining Certificateholders, in accordance with their
respective interests, all distributable amounts remaining in the Distribution
Account. Upon deposit by the Master Servicer of such distributable amounts, and
following such final Distribution Date, the Trustee shall release promptly to
the Seller or its designee the Mortgage Files for the remaining Mortgage Loans,
and the Master Servicer Collection Account and the Distribution Account shall
terminate, subject to the Trustee's obligation to hold any amounts payable to
the Certificateholders in trust without interest pending final distributions
pursuant to this Subsection 10.01(g).

        (g) If not all of the Certificateholders shall surrender their
Certificates for cancellation within six months after the time specified in the
above-mentioned written notice, the Trustee shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice, not all the Certificates shall have been
surrendered for cancellation, the Trustee may take appropriate steps, or appoint
any agent to take appropriate steps, to contact the remaining Certificateholders
concerning surrender of their Certificates, and the cost thereof shall be paid
out of the funds and other assets which remain subject to this Agreement.

        Section 10.02 ADDITIONAL TERMINATION REQUIREMENTS. (a) If the option of
the Seller to repurchase all the Mortgage Loans under Subsection 10.01(a)(i)
above is exercised, the Trust Fund and each of REMIC I and REMIC II shall be
terminated in accordance with the following additional requirements, unless the
Trustee has been furnished with an Opinion of Counsel to the effect that the
failure of the Trust to comply with the requirements of this Section 10.02 will
not (i) result in the imposition of taxes on "prohibited transactions" as
defined in Section 860F of the Code on each of REMIC I and REMIC II or (ii)
cause any REMIC to fail to qualify as a REMIC at any time that any Regular
Certificates are outstanding:

               (i) within 90 days prior to the final Distribution Date, at the
        written direction of the Seller, the Trustee, as agent for the
        respective Tax Matters Persons, shall adopt a plan of complete
        liquidation of REMIC I and REMIC II in the case of a termination under
        Subsection 10.01(a)(i), or a plan of complete liquidation of REMIC I in
        the case of a termination under Subsection 10.01(c), provided to it by
        the Seller meeting the requirements of a "qualified liquidation" under
        Section 860F of the Code and any regulations thereunder.

               (ii) the Seller shall notify the Trustee at the commencement of
        such 90-day liquidation period and, at or prior to the time of making of
        the final payment on the Certificates, the Trustee shall sell or
        otherwise dispose of all of the remaining assets of the Trust Fund in
        accordance with the terms hereof; and

               (iii) at or after the time of adoption of such a plan of complete
        liquidation of any of REMIC I and REMIC II and at or prior to the final
        Distribution Date, the Trustee shall sell

                                      -91-

<PAGE>

        for cash all of the assets of the Trust to or at the direction of the
        Seller, and REMIC I and REMIC II, as applicable, shall terminate at such
        time.

        (b) By their acceptance of the Residual Certificates, the Holders
thereof hereby (i) agree to adopt such a plan of complete liquidation of the

                            Miscellaneous Provisions

        Section 11.01 INTENT OF PARTIES. The parties intend that each of REMIC I
and REMIC II shall be treated as a REMIC for federal income tax purposes and
that the provisions of this Agreement should be construed in furtherance of this
intent.

        Section 11.02 AMENDMENT. (a) This Agreement may be amended from time to
time by EMC, the Seller, the Master Servicer, the Securities Administrator and
the Trustee, and the Servicing Agreements may be amended from time to time by
EMC, the Master Servicer and the Trustee, without notice to or the consent of
any of the Certificateholders, to cure any ambiguity, to correct or supplement
any provisions herein or therein that may be defective or inconsistent with any
other provisions herein or therein, to comply with any changes in the Code or to
make any other provisions with respect to matters or questions arising under
this Agreement which shall not be inconsistent with the provisions of this
Agreement; provided, however, that such action shall not, as evidenced by an
Opinion of Independent Counsel, addressed to the Trustee, adversely affect in
any material respect the interests of any Certificateholder.

        (b) This Agreement may also be amended from time to time by EMC, the
Master Servicer, the Seller, the Securities Administrator and the Trustee, and
the Servicing Agreements may also be amended from time to time by the Master
Servicer and the Trustee, with the consent of the Holders of Certificates
evidencing Fractional Undivided Interests aggregating not less than 51% of the
Trust Fund or of the applicable Class or Classes, if such amendment affects only
such Class or Classes, for the purpose of adding any provisions to or changing
in any manner or eliminating any of the provisions of this Agreement or of
modifying in any manner the rights of the Certificateholders; provided, however,
that no such amendment shall (i) reduce in any manner the amount of, or delay
the timing of, payments received on Mortgage Loans which are required to be
distributed on any Certificate without the consent of the Holder of such
Certificate, (ii) reduce the aforesaid percentage of Certificates the Holders of
which are required to consent to any such amendment, without the consent of the
Holders of all Certificates then outstanding, or (iii) cause REMIC I or REMIC II
to fail to qualify as a REMIC for federal income tax purposes, as evidenced by
an Opinion of Independent Counsel which shall be provided to the Trustee other
than at the Trustee's expense. Notwithstanding any other provision of this
Agreement, for purposes of the giving or withholding of consents pursuant to
Section 11.02(b), Certificates registered in the name of or held for the benefit
of the Seller, the Securities Administrator, the Master Servicer, or the Trustee
or any Affiliate thereof shall be entitled to vote their Fractional Undivided
Interests with respect to matters affecting such Certificates.

        (c) Promptly after the execution of any such amendment, the Trustee
shall furnish a copy of such amendment or written notification of the substance
of such amendment to each Certificateholder, with a copy to the Rating Agencies.

        (d)    In the case of an amendment under Subsection 11.02(b) above, it
shall not be necessary for the Certificateholders to approve the particular form
of such an amendment. Rather, it shall be sufficient if the Certificateholders
approve the substance of the amendment. The manner

                                      -93-

<PAGE>

of obtaining such consents and of evidencing the authorization of the execution
thereof by Certificateholders shall be subject to such reasonable regulations as
the Trustee may prescribe.

        (e) Prior to the execution of any amendment to this Agreement, the
Trustee shall be entitled to receive and rely upon an Opinion of Counsel stating
that the execution of such amendment is authorized or permitted by this
Agreement. The Trustee and the Securities Administrator may, but shall not be
obligated to, enter into any such amendment which affects the Trustee's or the
Securities Administrator's own respective rights, duties or immunities under
this Agreement.

        Section 11.03 RECORDATION OF AGREEMENT. To the extent permitted by
applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the Mortgaged Properties are situated, and
in any other appropriate public recording office or elsewhere. The Seller shall
effect such recordation, at the expense of the Trust upon the request in writing
of a Certificateholder, but only if such direction is accompanied by an Opinion
of Counsel (provided at the expense of the Certificateholder requesting
recordation) to the effect that such recordation would materially and
beneficially affect the interests of the Certificateholders or is required by
law.

        Section 11.04 LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS. (a) The death
or incapacity of any Certificateholder shall not terminate this Agreement or the
Trust, nor entitle such Certificateholder's legal representatives or heirs to
claim an accounting or to take any action or proceeding in any court for a
partition or winding up of the Trust, nor otherwise affect the rights,
obligations and liabilities of the parties hereto or any of them.

        (b) Except as expressly provided in this Agreement, no
Certificateholders shall have any right to vote or in any manner otherwise
control the operation and management of the Trust, or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Certificates, be construed so as to establish the Certificateholders from
time to time as partners or members of an association; nor shall any
Certificateholders be under any liability to any third Person by reason of any
action taken by the parties to this Agreement pursuant to any provision hereof.

        (c) No Certificateholder shall have any right by virtue of any provision
of this Agreement to institute any suit, action or proceeding in equity or at
law upon, under or with respect to this Agreement against the Seller, the
Securities Administrator, the Master Servicer or any successor to any such
parties unless (i) such Certificateholder previously shall have given to the
Trustee a written notice of a continuing default, as herein provided, (ii) the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% of the Trust Fund shall have made written request upon the
Trustee to institute such action, suit or proceeding in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs and expenses and liabilities to be incurred
therein or thereby, and (iii) the Trustee, for 60 days after its receipt of such
notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding.

        (d) No one or more Certificateholders shall have any right by virtue of
any provision of this Agreement to affect the rights of any other
Certificateholders or to obtain or seek to obtain

                                      -94-

<PAGE>

priority or preference over any other such Certificateholder, or to enforce any
right under this Agreement, except in the manner herein provided and for the
equal, ratable and common benefit of all Certificateholders. For the protection
and enforcement of the provisions of this Section 11.04, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

        Section 11.05 ACTS OF CERTIFICATEHOLDERS. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Agreement to be given or taken by Certificateholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Certificateholders in person or by an agent duly appointed in writing.
Except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is expressly required, to the Seller. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Agreement and conclusive in favor of the Trustee and the Seller,
if made in the manner provided in this Section 11.05.

        (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his or her individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his or her authority. The fact and date of the execution of any such
instrument or writing, or the authority of the individual executing the same,
may also be proved in any other manner which the Trustee deems sufficient.

        (c) The ownership of Certificates (notwithstanding any notation of
ownership or other writing on such Certificates, except an endorsement in
accordance with Section 5.02 made on a Certificate presented in accordance with
Section 5.04) shall be proved by the Certificate Register, and neither the
Trustee, the Securities Administrator, the Seller, the Master Servicer nor any
successor to any such parties shall be affected by any notice to the contrary.

        (d) Any request, demand, authorization, direction, notice, consent,
waiver or other action of the holder of any Certificate shall bind every future
holder of the same Certificate and the holder of every Certificate issued upon
the registration of transfer or exchange thereof, if applicable, or in lieu
thereof with respect to anything done, omitted or suffered to be done by the
Trustee, the Securities Administrator, the Seller, the Master Servicer or any
successor to any such party in reliance thereon, whether or not notation of such
action is made upon such Certificates.

        (e) In determining whether the Holders of the requisite percentage of
Certificates evidencing Fractional Undivided Interests have given any request,
demand, authorization, direction, notice, consent or waiver hereunder,
Certificates owned by the Trustee, the Securities Administrator, the Seller, the
Master Servicer or any Affiliate thereof shall be disregarded, except as
otherwise provided in Section 11.02(b) and except that, in determining whether
the Trustee shall be protected in relying upon any such request, demand,
authorization, direction, notice, consent or waiver, only Certificates which the
Trustee knows to be so owned shall be so disregarded. Certificates which have
been pledged in good faith to the Trustee, the Securities Administrator, the
Seller, the Master

                                      -95-

<PAGE>

Servicer or any Affiliate thereof may be regarded as outstanding if the pledgor
establishes to the satisfaction of the Trustee the pledgor's right to act with
respect to such Certificates and that the pledgor is not an Affiliate of the
Trustee, the Securities Administrator, the Seller, or the Master Servicer, as
the case may be.

        Section 11.06 GOVERNING LAW. THIS AGREEMENT AND THE CERTIFICATES SHALL
BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
REFERENCE TO ITS CONFLICT OF LAWS RULES AND THE OBLIGATIONS, RIGHTS AND REMEDIES

Mortgage Investments Inc. ("SAMI"). The Mortgage Loans were sold by EMC Mortgage
Corporation ("EMC") to SAMI. Wells Fargo Bank Minnesota, National Association
("Wells Fargo") will act as master servicer of the Mortgage Loans (the "Master
Servicer," which term includes any successors thereto under the Agreement
referred to below). The Trust Fund was created pursuant to the Pooling and
Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement"), among SAMI, as seller (the "Seller"), Wells Fargo Bank Minnesota,
National Association as master servicer and securities administrator, EMC
Mortgage Corporation and Bank One, National Association, as trustee (the
"Trustee"), a summary of certain of the pertinent provisions of which is set
forth hereafter. To the extent not defined herein, capitalized terms used herein
shall have the meaning ascribed to them in the Agreement. This Certificate is
issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of its
acceptance hereof assents and by which such Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Current Principal Amount hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Trustee will distribute on the 25th day
of each month, or, if such 25th day is not a Business Day, the immediately
following Business Day (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 (or if such last
day is not a Business Day, the Business Day immediately preceding such last day)
of the calendar month preceding the month of such Distribution Date, an amount
equal to the product of the Fractional Undivided Interest evidenced by this
Certificate and the amount (of interest and principal, if any) required to be
distributed to the Holders of Certificates of the same Class as this
Certificate. The Assumed Final Distribution Date is the Distribution Date in the
month immediately following the month of the latest scheduled maturity date of
any Mortgage Loan and is not likely to be the date on which the Current
Principal Amount of this Class of Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice. The
Initial Current Principal Amount of this Certificate is set forth above. The
Current Principal Amount hereof will be reduced to the extent of distributions
allocable to principal hereon and any Realized Losses allocable hereto.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in ten Classes. The Certificates, in the aggregate, evidence the entire
beneficial ownership interest in the Trust Fund formed pursuant to the
Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust Fund for payment hereunder and that
the Trustee is not liable to the

                                       A-3

<PAGE>

Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

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

                  The Agreement permits, with certain exceptions therein
provided; (i) the amendment thereof and the modification of the rights and
obligations of the Seller, the Master Servicer and the Trustee and the rights of
the Certificateholders under the Agreement from time to time by EMC, the Seller,
the Master Servicer, the Securities Administrator and the Trustee, and (ii) the
amendment of the Servicing Agreements by the Mater Servicer and the Trustee with
the consent of the Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than 51% of the Trust Fund (or in certain cases,
Holders of Certificates of affected Classes evidencing such percentage of the
Fractional Undivided Interests thereof). Any such consent by the Holder of this
Certificate shall be conclusive and binding on such Holder and upon all future
Holders of this Certificate and of any Certificate issued upon the transfer
hereof or in lieu hereof whether or not notation of such consent is made upon
this Certificate. The Agreement also permits the amendment thereof and of the
Servicing Agreements in certain limited circumstances, without the consent of
the Holders of any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Fractional Undivided Interest, as requested
by the Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Seller, the Master Servicer, the Trustee and any agent of any of
them may treat the Person in whose name this Certificate is registered as the
owner hereof for all purposes, and none of Seller, the Master Servicer, the
Trustee or any such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of the (A) final payment or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund

                                       A-4

<PAGE>

and (B) disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other assets of the Trust Fund in accordance with
the terms of the Agreement. Such optional repurchase may be made only on or
after the Distribution Date on which the aggregate unpaid principal balance of
the Mortgage Loans is less than the percentage of the aggregate Outstanding
Principal Balance specified in the Agreement of the Mortgage Loans at the
Cut-off Date. The exercise of such right will effect the early retirement of the
Certificates. In no event, however, will the Trust Fund created by the Agreement
continue beyond the expiration of 21 years after the death of certain persons
identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

sufficient to cover any tax or other governmental charge payable in connection
therewith. The Seller, the Master Servicer, the Trustee and any agent of any of
them may treat the Person in whose name this Certificate is registered as the
owner hereof for all purposes, and none of the Seller, the Master Servicer, the
Trustee or any such agent shall be affected by notice to the contrary.

created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of the (A) final payment or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and (B) disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate unpaid principal balance of the Mortgage Loans is less than the
percentage of the aggregate Outstanding Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an

         evidencing a fractional undivided interest in the distributions
         allocable to the Class [R-_] Certificates with respect to a Trust Fund
         consisting primarily of a pool of adjustable interest rate mortgage
         loans secured by first liens on one-to-four family residential
         properties and individual condominium units sold by STRUCTURED ASSET
         MORTGAGE INVESTMENTS INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Structured
Asset Mortgage Investments Inc., the Master Servicer or the Trustee referred to
below or any of their affiliates or any other person. Neither this Certificate
nor the underlying Mortgage Loans are guaranteed or insured by any governmental
entity or by Structured Asset Mortgage Investments Inc., the Master Servicer or
the Trustee or any of their affiliates or any other person. None of Structured
Asset Mortgage Investments Inc., the Master Servicer or any of their affiliates
will have any obligation with respect to any certificate or other obligation
secured by or payable from payments on the Certificates.

                  This certifies that ______________________________ is the
registered owner of the Fractional Undivided Interest evidenced hereby in the
beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust Fund") generally consisting of conventional
adjustable rate mortgage loans secured by first liens on one- to four- family
residences and individual condominium units (collectively, the "Mortgage Loans")
sold by Structured Asset Mortgage Investments Inc. ("SAMI"). The Mortgage Loans
were sold by EMC Mortgage Corporation ("EMC") to SAMI. Wells Fargo Bank
Minnesota, National Association ("Wells Fargo") will act as

                                      A-2-3

<PAGE>

master servicer of the Mortgage Loans (the "Master Servicer," which term
includes any successors thereto under the Agreement referred to below). The
Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as
of the Cut-off Date specified above (the "Agreement'), among SAMI, as seller
(the "Seller"), Wells Fargo Bank Minnesota, National Association as master
servicer and securities administrator, EMC Mortgage Corporation and Bank One,
National Association, as trustee (the "Trustee"), a summary of certain of the
pertinent provisions of which is set forth hereafter. To the extent not defined
herein, capitalized terms used herein shall have the meaning ascribed to them in
the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Current Principal Amount hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Trustee will distribute on the 25th day
of each month, or, if such 25th day is not a Business Day, the immediately
following Business Day (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 (or if such last
day is not a Business Day, the Business Day immediately preceding such last day)
of the calendar month preceding the month of such Distribution Date, an amount
equal to the product of the Fractional Undivided Interest evidenced by this
Certificate and the amount (of interest and principal, if any) required to be
distributed to the Holders of Certificates of the same Class as this
Certificate. The Assumed Final Distribution Date is the Distribution Date in the
month immediately following the month of the latest scheduled maturity date of
any Mortgage Loan and is not likely to be the date on which the Current
Principal Amount of this Class of Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register. Notwithstanding the above, the
final distribution on this Certificate will be made after due notice by the
Trustee of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the office or agency appointed by the Trustee
for that purpose and designated in such notice. The Initial Current Principal
Amount of this Certificate is set forth above. The Current Principal Amount
hereof will be reduced to the extent of distributions allocable to principal
hereon and any Realized Losses allocable hereto.

                  Each Holder of this Certificate will be deemed to have agreed
to be bound by the restrictions set forth in the Agreement to the effect that
(i) each person holding or acquiring any Ownership Interest in this Certificate
must be a United States Person and a Permitted Transferee, (ii) the transfer of
any Ownership Interest in this Certificate will be conditioned upon the delivery
to the Trustee of, among other things, an affidavit to the effect that it is a
United States Person and Permitted Transferee, (iii) any attempted or purported
transfer of any Ownership Interest in this Certificate in violation of such
restrictions will be absolutely null and void and will vest no rights in the
purported transferee, and (iv) if any person other than a United States Person
and a Permitted Transferee acquires any Ownership Interest in this Certificate
in violation of such restrictions, then the Seller will have the right, in its
sole discretion and without notice to the Holder of this

                                      A-2-4

<PAGE>

Certificate, to sell this Certificate to a purchaser selected by the Company,
which purchaser may be the Seller, or any affiliate of the Seller, on such terms
and conditions as the Seller may choose.

                  This certificate may not be acquired directly or indirectly
by, or on behalf of, an employee benefit plan or other retirement arrangement
which is subject to title I of the employee retirement income security act of
1974, as amended, and/or section 4975 of the internal revenue code of 1986, as
amended, unless the proposed transfer and/or holding of a certificate and the
servicing, management and/or operation of the trust and its assets: (1) will not
result in or constitute a nonexempt prohibited transaction and is permissible
under applicable law and (2) will not give rise to any additional fiduciary
obligations on the part of the seller, the master servicer or the trustee, which
must be evidenced by an opinion of counsel to such effect by or on behalf of an
institutional accredited investor.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in ten Classes. The Certificates, in the aggregate, evidence the entire
beneficial ownership interest in the Trust Fund formed pursuant to the
Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided; (i) the amendment thereof and the modification of the rights and
obligations of the Seller, the Master Servicer and the Trustee and the rights of
the Certificateholders under the Agreement from time to time by EMC, the Seller,
the Master Servicer, the Securities Administrator and the Trustee, and (ii) the
amendment of the Servicing Agreements by the Mater Servicer and the Trustee with
the consent of the Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than 51% of the Trust Fund (or in certain cases,
Holders of Certificates of affected Classes evidencing such percentage of the
Fractional Undivided Interests thereof). Any such consent by the Holder of this
Certificate shall be conclusive and binding on such Holder and upon all future
Holders of this Certificate and of any Certificate issued upon the transfer
hereof or in lieu hereof whether or not notation of such consent is made upon
this Certificate. The Agreement also permits the amendment thereof and of the
Servicing Agreements in certain limited circumstances, without the consent of
the Holders of any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and

                                      A-2-5

<PAGE>

thereupon one or more new Certificates in authorized denominations representing
a like aggregate Fractional Undivided Interest will be issued to the designated
transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Fractional Undivided Interest, as requested
by the Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Seller, the Master Servicer, the Trustee and any agent of any of
them may treat the Person in whose name this Certificate is registered as the
owner hereof for all purposes, and none of the Seller, the Master Servicer, the
Trustee or any such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of the (A) final payment or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and (B) disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate unpaid principal balance of the Mortgage Loans is less than the
percentage of the aggregate Outstanding Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                           1933, as amended (the "Act") or any applicable state
                           securities or "Blue Sky" laws, and are being sold to
                           us in a transaction that is exempt from the

                  (ii)     any information we desired concerning the
                           Certificates, including the Privately Offered
                           Certificates, the trust in which the Certificates
                           represent the entire beneficial ownership interest
                           (the "Trust") or any other matter we deemed relevant

                           Act and a sophisticated institutional investor;

                  (iv)     we are acquiring Privately Offered Certificates for

                  (v)      we agree the Privately Offered Certificates must be
                           held indefinitely by us (and may not be sold,
                           pledged, hypothecated or in any way disposed of)

                           acknowledge you have no obligation), the Privately

         The undersigned further certifies that it is purchasing a Privately
Offered Certificate for its own account or for the account of others that
independently qualify as "Qualified Institutional Buyers" as defined in Rule
144A. It is aware that the sale of the Privately Offered Certificates is being
made in reliance on its continued compliance with Rule 144A. It is aware that
the transferor may rely on the exemption from the provisions of Section 5 of the
Act provided by Rule 144A. The undersigned understands that the Privately
Offered Certificates may be resold, pledged or transferred only to (i) a person
reasonably believed to be a Qualified Institutional Buyer that purchases for its
own account or for the account of a Qualified Institutional Buyer to whom notice
is given that the resale, pledge or transfer is being made in reliance in Rule
144A, or (ii) an institutional "accredited investor," as such term is defined
under Rule 501 of the Act in a transaction that otherwise does not constitute a
public offering.

         The undersigned agrees that if at some future time it wishes to dispose
of or exchange any of the Privately Offered Certificates, it will not transfer
or exchange any of the Privately Offered Certificates to a Qualified
Institutional Buyer without first obtaining a Rule 144A and Related Matters
Certificate in the form hereof from the transferee and delivering such
certificate to the addressees hereof. Prior to making any transfer of Privately
Offered Certificates, if the proposed Transferee is an institutional "accredited
investor," the transferor shall obtain from the transferee and deliver to the
addressees hereof an Investment Letter in the form attached to the Pooling and
Servicing Agreement, dated as of March 1, 2002, among Structured Asset Mortgage
Investments Inc., Wells Fargo Bank Minnesota, National Association, EMC Mortgage
Corporation and Bank One, National Association, as Trustee, pursuant to
Certificates were issued.

         The undersigned certifies that it either: (i) is not acquiring the
Privately Offered Certificate directly or indirectly by, or on behalf of, an
employee benefit plan or other retirement arrangement which is subject to Title
I of the Employee Retirement Income Security Act of 1974, as amended, and/or
section 4975 of the Internal Revenue Code of 1986, as amended, or (ii) is
providing a representation or an opinion of counsel to the effect that the
proposed transfer and/or holding of a Privately Offered Certificate and the
servicing, management and/or operation of the Trust and its assets: (I) will not
result in any prohibited transaction which is not covered under a prohibited
transaction exemption, including, but not limited to, Prohibited Transaction
Exemption ("PTE") 84- 14, PTE 91-38, PTE 90-1, PTE 95-60, PTE 96-23 or Section
401(c) of ERISA and the regulations to be promulgated thereunder and (II) will
not give rise to any additional fiduciary duties on the part of the Seller, the
Master Servicer or the Trustee.

         If the Purchaser proposes that its Certificates be registered in the
name of a nominee on its behalf, the Purchaser has identified such nominee
below, and has caused such nominee to complete the Nominee Acknowledgment at the
end of this letter.

Trustee for the purposes of receiving and holding certain documents and other
instruments delivered by the Company or the Master Servicer under the Pooling
and Servicing Agreement and the Servicers under their respective Servicing
Agreements, all upon the terms and conditions and subject to the limitations

                  NOW, THEREFORE, in consideration of the premises and the
mutual covenants and agreements hereinafter set forth, the Trustee, the Company,
the Master Servicer and the Custodian hereby agree as follows:

                                   ARTICLE I.
                                   DEFINITIONS

                  Capitalized terms used in this Agreement and not defined
herein shall have the meanings assigned in the Original Pooling and Servicing
Agreement, unless otherwise required by the context herein.

                                   ARTICLE II.
                          CUSTODY OF MORTGAGE DOCUMENTS

                  Section 2.1. CUSTODIAN TO ACT AS AGENT: ACCEPTANCE OF MORTGAGE
FILES. The Custodian, as the duly appointed agent of the Trustee for these
purposes, acknowledges (subject to any exceptions noted in the Initial
Certification referred to in Section 2.3(a) receipt of the Mortgage

<PAGE>

Files relating to the Mortgage Loans identified on the schedule attached hereto
(the "Mortgage Files") and declares that it holds and will hold such Mortgage
Files as agent for the Trustee, in trust, for the use and benefit of all present
and future Certificateholders.

                  Section 2.2. RECORDATION OF ASSIGNMENTS. If any Mortgage File
includes one or more assignments of Mortgage to the Trustee in a state which is
specifically excluded from the Opinion of Counsel delivered by the Seller to the
Trustee (with a copy to the Custodian) pursuant to the provisions of Section
2.01 of the Pooling and Servicing Agreement, each such assignment shall be
delivered by the Custodian to the Company for the purpose of recording it in the
appropriate public office for real property records, and the Company, at no
expense to the Custodian, shall promptly cause to be recorded in the appropriate
public office for real property records each such assignment of Mortgage and,
upon receipt thereof from such public office, shall return each such assignment
of Mortgage to the Custodian.

                  Section 2.3.   REVIEW OF MORTGAGE FILES.

                  (a) On or prior to the Closing Date, in accordance with
Section 2.02 of the Pooling and Servicing Agreement, the Custodian shall deliver
to the Trustee an Initial Certification in the form annexed hereto as Exhibit
One evidencing receipt (subject to any exceptions noted therein) of a Mortgage
File for each of the Mortgage Loans listed on the Schedule attached hereto (the
"Mortgage Loan Schedule").

                  (b) Within 90 days of the Closing Date, the Custodian agrees,
for the benefit of Certificateholders, to review, in accordance with the
provisions of Section 2.02 of the Pooling and Servicing Agreement, each such
document, and shall deliver to the Trustee an Interim Certification in the form
annexed hereto as Exhibit Two to the effect that all such documents have been
executed and received and that such documents relate to the Mortgage Loans
identified on the Mortgage Loan Schedule, except for any exceptions listed on
Schedule A attached to such Interim Certification. The Custodian shall be under
no duty or obligation to inspect, review or examine said documents, instruments,
certificates or other papers to determine that the same are genuine,
enforceable, or appropriate for the represented purpose or that they have
actually been recorded or that they are other than what they purport to be on
their face.

                  (c) Not later than 180 days after the Closing Date, the
Custodian shall review the Mortgage Files as provided in Section 2.02 of the
Pooling and Servicing Agreement and deliver to the Trustee a Final Certification
in the form annexed hereto as Exhibit Three evidencing the completeness of the
Mortgage Files.

                  (d) In reviewing the Mortgage Files as provided herein and in
the Pooling and Servicing Agreement, the Custodian shall make no representation
as to and shall not be responsible to verify (i) the validity, legality,
enforceability, due authorization, recordability, sufficiency or genuineness of
any of the documents included in any Mortgage File or (ii) the collectibility,
insurability, effectiveness or suitability of any of the documents in any
Mortgage File.

                                       -2-

<PAGE>

         Upon receipt of written request from the Trustee, the Custodian shall
as soon as practicable supply the Trustee with a list of all of the documents
relating to the Mortgage Loans then contained in the Mortgage Files.

                  Section 2.4. NOTIFICATION OF BREACHES OF REPRESENTATIONS AND
WARRANTIES. Upon discovery by the Custodian of a breach of any representation or
warranty made by the Company as set forth in the Pooling and Servicing Agreement
with respect to a Mortgage Loan relating to a Mortgage File, the Custodian shall
give prompt written notice to the Company, the related Servicer and the Trustee.

                  Section 2.5. CUSTODIAN TO COOPERATE: RELEASE OF MORTGAGE
FILES. Upon receipt of written notice from the Trustee that the Mortgage Loan
Seller has repurchased a Mortgage Loan pursuant to Article II of the Pooling and
Servicing Agreement, and that the purchase price therefore has been deposited in
the Master Servicer Collection Account or the Distribution Account, then the
Custodian agrees to promptly release to the Mortgage Loan Seller the related
Mortgage File.

                  Upon the Custodian's receipt of a request for release (a
"Request for Release") substantially in the form of Exhibit D to the Pooling and
Servicing Agreement signed by a Servicing Officer of the related Servicer
stating that it has received payment in full of a Mortgage Loan or that payment
in full will be escrowed in a manner customary for such purposes, the Custodian
agrees promptly to release to the related Servicer the related Mortgage File.
The Company shall deliver to the Custodian and the Custodian agrees to accept
the Mortgage Note and other documents constituting the Mortgage File with
respect to any Substitute Mortgage Loan.

                  From time to time as is appropriate for the servicing or
foreclosure of any Mortgage Loan, including, for this purpose, collection under
any Primary Insurance Policy, the related Servicer shall deliver to the
Custodian a Request for Release signed by a Servicing Officer requesting that
possession of all of the Mortgage File be released to the related Servicer and
certifying as to the reason for such release and that such release will not
invalidate any insurance coverage provided in respect of the Mortgage Loan under
any of the Insurance Policies. Upon receipt of the foregoing, the Custodian
shall deliver the Mortgage File to the related Servicer. The related Servicer
shall cause each Mortgage File or any document therein so released to be
returned to the Custodian when the need therefore by the related Servicer no
longer exists, unless (i) the Mortgage Loan has been liquidated and the
Liquidation Proceeds relating to the Mortgage Loan have been deposited in the
Master Servicer Collection Account or the Distribution Account or (ii) the
Mortgage File or such document has been delivered to an attorney, or to a public
trustee or other public official as required by law, for purposes of initiating
or pursuing legal action or other proceedings for the foreclosure of the
Mortgaged Property either judicially or non-judicially, and the related Servicer
has delivered to the Custodian a certificate of a Servicing Officer certifying
as to the name and address of the Person to which such Mortgage File or such
document was delivered and the purpose or purposes of such delivery.

                  At any time that a Servicer is required to deliver to the
Custodian a Request for Release, the Servicer shall deliver two copies of the
Request for Release if delivered in hard copy or the Servicer may furnish such
Request for Release electronically to the Custodian, in which event the
Servicing Officer transmitting the same shall be deemed to have signed the
Request for Release.

                                       -3-

<PAGE>

In connection with any Request for Release of a Mortgage File because of a
repurchase of a Mortgage Loan, such Request for Release shall be accompanied by
an assignment of mortgage, without recourse, from the Trustee to the Mortgage
Loan Seller and the related Mortgage Note shall be endorsed without recourse by
the Trustee and be returned to the Mortgage Loan Seller. In connection with any
Request for Release of a Mortgage File because of the payment in full of a
Mortgage Loan, such Request for Release shall be accompanied by a certificate of
satisfaction or other similar instrument to be executed by or on behalf of the
Trustee and returned to the related Servicer.

                  Section 2.6. ASSUMPTION AGREEMENTS. In the event that any
assumption agreement or substitution of liability agreement is entered into with
respect to any Mortgage Loan subject to this Agreement in accordance with the
terms and provisions of the Pooling and Servicing Agreement, the Master
Servicer, to the extent provided in the related Servicing Agreement, shall cause
the related Servicer to notify the Custodian that such assumption or
substitution agreement has been completed by forwarding to the Custodian the
original of such assumption or substitution agreement, which shall be added to
the related Mortgage File and, for all purposes, shall be considered a part of
such Mortgage File to the same extent as all other documents and instruments
constituting parts thereof.

                                  ARTICLE III.
                            CONCERNING THE CUSTODIAN

                  Section 3.1. Custodian a Bailee and Agent of the Trustee. With
respect to each Mortgage Note, Mortgage and other documents constituting each
Mortgage File which are delivered to the Custodian, the Custodian is exclusively
the bailee and agent of the Trustee and has no instructions to hold any Mortgage
Note or Mortgage for the benefit of any person other than the Trustee and the
Certificateholders and undertakes to perform such duties and only such duties as
are specifically set forth in this Agreement. Except upon compliance with the
provisions of Section 2.5 of this Agreement, no Mortgage Note, Mortgage or
Mortgage File shall be delivered by the Custodian to the Company, the Servicers
or the Master Servicer or otherwise released from the possession of the
Custodian.

                  Section 3.2.   Reserved.

                  Section 3.3. CUSTODIAN MAY OWN CERTIFICATES. The Custodian in
its individual or any other capacity may become the owner or pledgee of
Certificates with the same rights it would have if it were not Custodian.

                  Section 3.4. MASTER SERVICER TO PAY CUSTODIAN'S FEES AND
EXPENSES. The Master Servicer covenants and agrees to pay to the Custodian from
time to time, and the Custodian shall be entitled to, reasonable compensation
for all services rendered by it in the exercise and performance of any of the
powers and duties hereunder of the Custodian, and the Master Servicer will pay
or reimburse the Custodian upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Custodian in accordance with
any of the provisions of this Agreement (including the reasonable compensation
and the expenses and disbursements of its counsel and of all persons not
regularly in its employ), except any such expense, disbursement or advance as
may

                                       -4-

<PAGE>

arise from its negligence or bad faith or to the extent that such cost or
expense is indemnified by the Company pursuant to the Pooling and Servicing
Agreement.

                  Section 3.5. CUSTODIAN MAY RESIGN TRUSTEE MAY REMOVE
CUSTODIAN. The Custodian may resign from the obligations and duties hereby
imposed upon it as such obligations and duties relate to its acting as Custodian
of the Mortgage Loans. Upon receiving such notice of resignation, the Trustee
shall either take custody of the Mortgage Files itself and give prompt notice
thereof to the Company, the Master Servicer and the Custodian, or promptly
appoint a successor Custodian by written instrument, in duplicate, one copy of
which instrument shall be delivered to the resigning Custodian and one copy to
the successor Custodian. If the Trustee shall not have taken custody of the
Mortgage Files and no successor Custodian shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Custodian may petition any court of competent
jurisdiction for the appointment of a successor Custodian.

                  The Trustee may remove the Custodian at any time with the
consent of the Master Servicer. In such event, the Trustee shall appoint, or
petition a court of competent jurisdiction to appoint, a successor Custodian
hereunder. Any successor Custodian shall be a depository institution subject to
supervision or examination by federal or state authority, shall be able to
satisfy the other requirements contained in Section 3.7 and shall be
unaffiliated with the Servicer or the Company.

                  Any resignation or removal of the Custodian and appointment of
a successor Custodian pursuant to any of the provisions of this Section 3.5
shall become effective upon acceptance of appointment by the successor
Custodian. The Trustee shall give prompt notice to the Company and the Master
Servicer of the appointment of any successor Custodian. No successor Custodian
shall be appointed by the Trustee without the prior approval of the Company and
the Master Servicer.

                  Section 3.6. MERGER OR CONSOLIDATION OF CUSTODIAN. Any Person
into which the Custodian may be merged or converted or with which it may be
consolidated, or any Person resulting from any merger, conversion or
consolidation to which the Custodian shall be a party, or any Person succeeding
to the business of the Custodian, shall be the successor of the Custodian
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

                  Section 3.7. REPRESENTATIONS OF THE CUSTODIAN. The Custodian
hereby represents that it is a depository institution subject to supervision or
examination by a federal or state authority, has a combined capital and surplus
of at least $15,000,000 and is qualified to do business in the jurisdictions in
which it will hold any Mortgage File.

                                   ARTICLE IV.
                            MISCELLANEOUS PROVISIONS

                  Section 4.1. NOTICES. All notices, requests, consents and
demands and other communications required under this Agreement or pursuant to
any other instrument or document delivered hereunder shall be in writing and,
unless otherwise specifically provided, may be delivered personally, by telegram
or telex, or by registered or certified mail, postage prepaid, return receipt

                                       -5-

requested, at the addresses specified on the signature page hereof (unless
changed by the particular party whose address is stated herein by similar notice
in writing), in which case the notice will be deemed delivered when received.

                  Section 4.2. AMENDMENTS. No modification or amendment of or
supplement to this Agreement shall be valid or effective unless the same is in
writing and signed by all parties hereto, and neither the Company, the Master
Servicer nor the Trustee shall enter into any amendment hereof except as
permitted by the Pooling and Servicing Agreement. The Trustee shall give prompt
notice to the Custodian of any amendment or supplement to the Pooling and
Servicing Agreement and furnish the Custodian with written copies thereof.

                  Section 4.3. GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED A
CONTRACT MADE UNDER THE LAWS OF THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND
ENFORCED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

                  Section 4.4. RECORDATION OF AGREEMENT. To the extent permitted
by applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated, and in any other appropriate public recording office or elsewhere,
such recordation to be effected by the Company and at the Trust's expense on
direction by the Trustee, but only upon direction accompanied by an Opinion of
Counsel reasonably satisfactory to the Company to the effect that the failure to
effect such recordation is likely to materially and adversely affect the
interests of the Certificateholders.

                  For the purpose of facilitating the recordation of this
Agreement as herein provided and for other purposes, this Agreement may be
executed simultaneously in any number of counterparts, each of which
counterparts shall be deemed to be an original, and such counterparts shall
constitute but one and the same instrument.

                  Section 4.5. SEVERABILITY OF PROVISIONS. If any one or more of
the covenants, agreements, provisions or terms of this Agreement shall be for
any reason whatsoever held invalid, then such covenants, agreements, provisions
or terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement or of the Certificates
or the rights of the holders thereof.

                         POOLING AND SERVICING AGREEMENT
                         -------------------------------

         Pooling and Servicing Agreement dated as of March 1, 2002, among
Structured Asset Mortgage Investments Inc., a Delaware corporation, as seller
(the "Seller"), Bank One, National Association, a national banking association,
not in its individual capacity but solely as trustee (the "Trustee"), Wells
Fargo Bank Minnesota, National Association, as master servicer (in such
capacity, the "Master Servicer"), Wells Fargo Bank Minnesota, National
Association, as securities administrator (in such capacity, the "Securities
Administrator") and EMC Mortgage Corporation ("EMC").

                              PRELIMINARY STATEMENT

         On or prior to the Closing Date, the Seller acquired the Mortgage Loans
from EMC. On the Closing Date, the Seller will sell the Mortgage Loans and
certain other property to the Trust Fund and receive in consideration therefor
Certificates evidencing the entire beneficial ownership interest in the Trust
Fund.

         The Trustee on behalf of the Trust shall make an election for the
assets constituting REMIC I to be treated for federal income tax purposes as a
REMIC. On the Startup Day, the REMIC I Regular Interests will be designated
"regular interests" in such REMIC and the Class R-I Certificate will be
designated the "residual interests" in such REMIC.

         The Trustee on behalf of the Trust shall make an election for the
assets constituting REMIC II to be treated for federal income tax purposes as a
REMIC. On the Startup Day, the REMIC II Regular Certificates will be designated
"regular interests" in such REMIC and the Class R-II Certificate will be
designated the "residual interests" in such REMIC.

         The Mortgage Loans will have an Outstanding Principal Balance as of the
Cut-off Date, after deducting all Scheduled Principal due on or before the
Cut-off Date, of approximately $312,798,664. The initial principal amount of the
Certificates will not exceed such Outstanding Principal Balance.

         In consideration of the mutual agreements herein contained, the Seller,
the Master Servicer, the Securities Administrator, EMC and the Trustee agree as
follows:

(y) as provided in the Servicing Agreement, to the extent applicable to

                          Conveyance of Mortgage Loans;
                        Original Issuance of Certificates

         Section 2.01 CONVEYANCE OF MORTGAGE LOANS TO TRUSTEE. (a) The Seller
concurrently with the execution and delivery of this Agreement, sells, transfers
and assigns to the Trust without recourse all its right, title and interest in
and to (i) the Mortgage Loans identified in the Mortgage Loan Schedule,
including all interest and principal due with respect to the Mortgage Loans
after the Cut-off Date, but excluding any payments of principal and interest due
on or prior to the Cut-off Date; (ii) such assets relating to the Mortgage Loans
as from time to time may be held by the Servicer in Protected Accounts, and the
Trustee in the Distribution Account for the benefit of the Trustee on behalf of
the Certificateholders, (iii) any REO Property, (iv) the Required Insurance
Policies and any amounts paid or payable by the insurer under any Insurance
Policy (to the extent the mortgagee has a claim thereto), (v) the Mortgage Loan
Purchase Agreement to the extent provided in Subsection 2.03(a), (vi) the rights
with respect to the Servicing Agreements as assigned to the Trustee on behalf of
the Certificateholders by the Assignment Agreement and (vii) any proceeds of the
foregoing. Although it is the intent of the parties to this Agreement that the
conveyance of the Seller's right, title and interest in and to the Mortgage
Loans and other assets in the Trust Fund pursuant to this Agreement shall
constitute a purchase and sale and not a loan, in the event that such conveyance
is deemed to be a loan, it is the intent of the parties to this Agreement that
the Seller shall be deemed to have granted to the Trustee a first priority
perfected security interest in all of the Seller's right, title and interest in,
to and under the Mortgage Loans and other assets in the Trust Fund, and that
this Agreement shall constitute a security agreement under applicable law.

         (b) In connection with the above transfer and assignment, the Seller
hereby deposits with the Trustee or the Custodian, as its agent, with respect to
each Mortgage Loan, (i) the original Mortgage Note, endorsed without recourse to
the order of the Trustee and showing an unbroken chain of endorsements from the
original payee thereof to the Person endorsing it to the Trustee, or lost note
affidavit, (ii) the original Security Instrument, which shall have been
recorded, with evidence of such recording indicated thereon, (iii) a certified
copy of the assignment (which may be in the form of a blanket assignment if
permitted in the jurisdiction in which the Mortgaged Property is located) to
"Bank One, National Association, as Trustee", with evidence of recording with
respect to each Mortgage Loan in the name of the Trustee thereon (or if clause
(x) in the proviso below applies or for Mortgage Loans with respect to which the
related Mortgaged Property is located in a state other than Maryland or an
Opinion of Counsel has been provided as set forth in this Section 2.01(b), shall
be in recordable form), (iv) all intervening assignments of the Security
Instrument, if applicable and only to the extent available to the Seller with
evidence of recording thereon, (v) the original or a copy of the policy or
certificate of primary mortgage guaranty insurance, to the extent available, if
any, (vi) the original policy of title insurance or mortgagee's certificate of
title insurance or commitment or binder for title insurance and (vii) originals
of all modification agreements, if applicable and available;

PROVIDED, HOWEVER, that in lieu of the foregoing, the Seller may deliver the
following documents, under the circumstances set forth below: (x) in lieu of the
original Security Instrument, assignments

                                      -27-

<PAGE>

to the Trustee or intervening assignments thereof which have been delivered, are
being delivered or will, upon receipt of recording information relating to the
Security Instrument required to be included thereon, be delivered to recording
offices for recording and have not been returned to the Seller in time to permit
their delivery as specified above, the Seller may deliver a true copy thereof
with a certification by the Seller, on the face of such copy, substantially as
follows: "Certified to be a true and correct copy of the original, which has
been transmitted for recording"; (y) in lieu of the Security Instrument,
assignment to the Trustee or intervening assignments thereof, if the applicable
jurisdiction retains the originals of such documents (as evidenced by a
certification from the Seller to such effect) the Seller may deliver photocopies
of such documents containing an original certification by the judicial or other
governmental authority of the jurisdiction where such documents were recorded;
and (z) the Seller shall not be required to deliver intervening assignments or
Mortgage Note endorsements between the Underlying Seller and EMC Mortgage
Corporation, between EMC Mortgage Corporation and the Depositor, and between the
Depositor and the Trustee; and provided, further, however, that in the case of
Mortgage Loans which have been prepaid in full after the Cut-off Date and prior
to the Closing Date, the Seller, in lieu of delivering the above documents, may
deliver to the Trustee or the Custodian, as its agent, a certification to such
effect and shall deposit all amounts paid in respect of such Mortgage Loans in
the Distribution Account on the Closing Date. The Seller shall deliver such
original documents (including any original documents as to which certified
copies had previously been delivered) to the Trustee or the Custodian, as its
agent, promptly after they are received. The Seller shall cause, at its expense,
the assignment of the Security Instrument to the Trustee to be recorded not
later than 180 days after the Closing Date, unless such recordation is not
required by the Rating Agencies or an Opinion of Counsel has been provided to
the Trustee (with a copy to the Custodian) which states that recordation of such
Security Instrument is not required to protect the interests of the
Certificateholders in the related Mortgage Loans; provided, however, that each
assignment shall be submitted for recording by the Seller in the manner
described above, at no expense to the Trust or the Trustee or the Custodian, as
its agent, upon the earliest to occur of : (i) reasonable direction by the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 25% of the Trust, (ii) the occurrence of an Event of Default,
(iii) the occurrence of a bankruptcy, insolvency or foreclosure relating to the
Seller and (iv) the occurrence of a servicing transfer as described in Section
8.02 hereof. Notwithstanding the foregoing, if the Seller fails to pay the cost
of recording the assignments, such expense will be paid by the Trustee and the
Trustee shall be reimbursed for such expenses by the Trust in accordance with
Section 9.05.

         Section 2.02 ACCEPTANCE OF MORTGAGE LOANS BY TRUSTEE. (a) The Trustee
acknowledges the sale, transfer and assignment of the Trust to it by the Seller
and receipt of, subject to further review and the exceptions which may be noted
pursuant to the procedures described below, and declares that it holds, the
documents (or certified copies thereof) delivered to it pursuant to Section
2.01, and declares that it will continue to hold those documents and any
amendments, replacements or supplements thereto and all other assets of the
Trust Fund delivered to it as Trustee in trust for the use and benefit of all
present and future Holders of the Certificates. On the Closing Date, the
Custodian, with respect to the Mortgage Loans, shall acknowledge with respect to
each Mortgage Loan by an Initial Certification substantially in the form of
Exhibit One to the Custodial Agreement receipt of the Mortgage File, but without
review of such Mortgage File, except to the extent necessary to confirm that
such Mortgage File contains the related Mortgage Note or lost note affidavit. No
later than 90 days after the Closing Date (or, with respect to any Substitute
Mortgage

                                      -28-

<PAGE>

Loan, within five Business Days after the receipt by the Trustee or Custodian
thereof), the Trustee agrees, for the benefit of the Certificateholders, to
review or cause to be reviewed by the Custodian on its behalf (under the
Custodial Agreement), each Mortgage File delivered to it and to execute and
deliver, or cause to be executed and delivered, to the Seller and the Master
Servicer an Interim Certification substantially in the form annexed as Exhibit
Two to the Custodial Agreement. In conducting such review, the Trustee or
Custodian will ascertain whether all required documents have been executed and
received, and based on the Mortgage Loan Schedule, whether those documents
relate, determined on the basis of the Mortgagor name, original principal
balance and loan number, to the Mortgage Loans it has received, as identified in
the Mortgage Loan Schedule. In performing any such review, the Trustee or the
Custodian, as its agent, may conclusively rely on the purported due execution
and genuineness of any such document and on the purported genuineness of any
signature thereon. If the Trustee or the Custodian, as its agent, finds any
document constituting part of the Mortgage File not to have been executed or
received, or to be unrelated to the Mortgage Loans identified in Exhibit B or to
appear to be defective on its face, the Trustee or the Custodian, as its agent,
shall promptly notify the Mortgage Loan Seller. In accordance with the Mortgage
Loan Purchase Agreement, the Mortgage Loan Seller shall correct or cure any such
defect within ninety (90) days from the date of notice from the Trustee or the
Custodian, as its agent, of the defect and if the Mortgage Loan Seller fails to
correct or cure the defect within such period, and such defect materially and
adversely affects the interests of the Certificateholders in the related
Mortgage Loan, the Trustee or the Custodian, as its agent, shall enforce the
Mortgage Loan Seller's obligation pursuant to the Mortgage Loan Purchase
Agreement, within 90 days from the Trustee's or the Custodian's notification, to
purchase such Mortgage Loan at the Repurchase Price; provided that, if such
defect would cause the Mortgage Loan to be other than a "qualified mortgage" as
defined in Section 860G(a)(3) of the Code, any such cure or repurchase must
occur within 90 days from the date such breach was discovered; provided,
however, that if such defect relates solely to the inability of the Mortgage
Loan Seller to deliver the original Security Instrument or intervening
assignments thereof, or a certified copy because the originals of such
documents, or a certified copy have not been returned by the applicable
jurisdiction, the Mortgage Loan Seller shall not be required to purchase such
Mortgage Loan if the Mortgage Loan Seller delivers such original documents or
certified copy promptly upon receipt, but in no event later than 360 days after
the Closing Date. The foregoing repurchase obligation shall not apply in the
event that the Mortgage Loan Seller cannot deliver such original or copy of any
document submitted for recording to the appropriate recording office in the
applicable jurisdiction because such document has not been returned by such
office; provided that the Mortgage Loan Seller shall instead deliver a recording
receipt of such recording office or, if such receipt is not available, a
certificate confirming that such documents have been accepted for recording, and
delivery to the Trustee or the Custodian, as its agent, shall be effected by the
Mortgage Loan Seller within thirty days of its receipt of the original recorded
document.

         (b) No later than 180 days after the Closing Date, the Trustee or the
Custodian, as its agent, will review, for the benefit of the Certificateholders,
the Mortgage Files delivered to it and will execute and deliver or cause to be
executed and delivered to the Seller a Final Certification substantially in the
form annexed as Exhibit Three to the Custodial Agreement. In conducting such
review, the Trustee or the Custodian, as its agent, will ascertain whether an
original of each document required to be recorded has been returned from the
recording office with evidence of recording thereon or a certified copy has been
obtained from the recording office. If the Trustee or the Custodian, as its
agent, finds any document constituting part of the Mortgage File has not been

                                      -29-

<PAGE>

received, or to be unrelated, determined on the basis of the Mortgagor name,
original principal balance and loan number, to the Mortgage Loans identified in
Exhibit B or to appear defective on its face, the Trustee or the Custodian, as
its agent, shall promptly notify the Mortgage Loan Seller (provided, however,
that with respect to those documents described in subsection (b)(iv), (b)(v) and
(b)(vii) of Section 2.01, the Trustee's obligations shall extend only to the
documents actually delivered pursuant to such subsections). In accordance with
the Mortgage Loan Purchase Agreement, the Mortgage Loan Seller shall correct or
cure any such defect or EMC shall deliver to the Trustee an Opinion of Counsel
to the effect that such defect does not materially or adversely affect the
interests of Certificateholders in such Mortgage Loan within 90 days from the
date of notice from the Trustee of the defect and if the Mortgage Loan Seller is
unable to cure such defect within such period, and if such defect materially and
adversely affects the interests of the Certificateholders in the related
Mortgage Loan, the Trustee shall enforce the Mortgage Loan Seller's obligation
under the Mortgage Loan Purchase Agreement to purchase such Mortgage Loan at the
Repurchase Price, provided, however, that if such defect relates solely to the
inability of the Mortgage Loan Seller to deliver the original Security
Instrument or intervening assignments thereof, or a certified copy, because the
originals of such documents. or a certified copy, have not been returned by the
applicable jurisdiction, the Mortgage Loan Seller shall not be required to
purchase such Mortgage Loan, if the Mortgage Loan Seller delivers such original
documents or certified copy promptly upon receipt, but in no event later than
360 days after the Closing Date.

         (c) In the event that a Mortgage Loan is purchased by the Mortgage Loan
Seller in accordance with Subsections 2.02(a) or (b) above, the Mortgage Loan
Seller shall remit to the Trustee the Repurchase Price for deposit in the
Distribution Account and the Mortgage Loan Seller shall provide to the Trustee
written notification detailing the components of the Repurchase Price. Upon
deposit of the Repurchase Price in the Distribution Account, the Seller shall
notify the Trustee and the Trustee or the Custodian, as its agent (upon receipt
of a Request for Release in the form of Exhibit D attached hereto with respect
to such Mortgage Loan), shall release to the Mortgage Loan Seller the related
Mortgage File and the Trustee shall execute and deliver all instruments of
transfer or assignment, without recourse, furnished to it by the Mortgage Loan
Seller as are necessary to vest in the Mortgage Loan Seller title to and rights
under the Mortgage Loan. Such purchase shall be deemed to have occurred on the
date on which the Repurchase Price in available funds is received by the
Trustee. The Trustee shall amend the Mortgage Loan Schedule, which was
previously delivered to it by Seller in a form agreed to between the Seller and
the Trustee, to reflect such repurchase and shall promptly notify the Rating
Agencies and the Master Servicer of such amendment. The obligation of the
Mortgage Loan Seller to repurchase any Mortgage Loan as to which such a defect
in a constituent document exists shall be the sole remedy respecting such defect
available to the Certificateholders or to the Trustee on their behalf.

         Section 2.03 ASSIGNMENT OF INTEREST IN THE MORTGAGE LOAN PURCHASE
AGREEMENT. (a) The Seller hereby assigns to the Trustee, on behalf of the
Certificateholders, all of its right, title and interest in the Mortgage Loan
Purchase Agreement, including but not limited to Seller's rights and obligations
pursuant to the Servicing Agreements (noting that the Mortgage Loan Seller has
retained the right in the event of breach of the representations, warranties and
covenants, if any, with respect to the related Mortgage Loans of the Servicer
under the related Servicing Agreement to enforce the provisions thereof and to
seek all or any available remedies). The obligations of the Mortgage Loan Seller
to substitute or repurchase, as applicable, a Mortgage Loan shall be the
Trustee's and the

                                      -30-

<PAGE>

Certificateholders' sole remedy for any breach thereof. At the request of the
Trustee, the Seller shall take such actions as may be necessary to enforce the
above right, title and interest on behalf of the Trustee and the
Certificateholders or shall execute such further documents as the Trustee may
reasonably require in order to enable the Trustee to carry out such enforcement.

         (b) If the Seller, the Master Servicer or the Trustee discovers a
breach of any of the representations and warranties set forth in the Mortgage
Loan Purchase Agreement, which breach materially and adversely affects the value
of the interests of Certificateholders or the Trustee in the related Mortgage
Loan, the party discovering the breach shall give prompt written notice of the
breach to the other parties. The Mortgage Loan Seller, within 90 days of its
discovery or receipt of notice that such breach has occurred (whichever occurs
earlier), shall cure the breach in all material respects or, subject to the
Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as
applicable, shall purchase the Mortgage Loan or any property acquired with
respect thereto from the Trustee; provided, however, that if there is a breach
of any representation set forth in the Mortgage Loan Purchase Agreement or
Section 2.04 of this Agreement, as applicable, and the Mortgage Loan or the
related property acquired with respect thereto has been sold, then the Mortgage
Loan Seller shall pay, in lieu of the Repurchase Price, any excess of the
Repurchase Price over the Net Liquidation Proceeds received upon such sale. (If
the Net Liquidation Proceeds exceed the Repurchase Price, any excess shall be
paid to the Mortgage Loan Seller to the extent not required by law to be paid to
the borrower.) Any such purchase by the Mortgage Loan Seller shall be made by
providing an amount equal to the Repurchase Price to the Trustee for deposit in
the Distribution Account and written notification detailing the components of
such Repurchase Price. The Seller shall notify the Trustee and submit to the
Trustee or the Custodian, as its agent, a Request for Release in the form of
Exhibit D attached hereto, and the Trustee shall release, or the Trustee shall
cause the Custodian to release, to the Mortgage Loan Seller the related Mortgage
File and the Trustee shall execute and deliver all instruments of transfer or
assignment furnished to it by the Mortgage Loan Seller, without recourse, as are
necessary to vest in the Mortgage Loan Seller title to and rights under the
Mortgage Loan or any property acquired with respect thereto. Such purchase shall
be deemed to have occurred on the date on which the Repurchase Price in
available funds is received by the Trustee. The Trustee shall amend the Mortgage
Loan Schedule to reflect such repurchase and shall promptly notify the Master
Servicer and the Rating Agencies of such amendment. Enforcement of the
obligation of the Mortgage Loan Seller to purchase (or substitute a Substitute
Mortgage Loan for) any Mortgage Loan or any property acquired with respect
thereto (or pay the Repurchase Price as set forth in the above proviso) as to
which a breach has occurred and is continuing shall constitute the sole remedy
respecting such breach available to the Certificateholders or the Trustee on
their behalf.

         Section 2.04 SUBSTITUTION OF MORTGAGE LOANS. Notwithstanding anything
to the contrary in this Agreement, in lieu of purchasing a Mortgage Loan
pursuant to the Mortgage Loan Purchase Agreement or Sections 2.02 or 2.03 of
this Agreement, the Mortgage Loan Seller may, no later than the date by which
such purchase by the Mortgage Loan Seller would otherwise be required, tender to
the Trustee a Substitute Mortgage Loan accompanied by a certificate of an
authorized officer of the Mortgage Loan Seller that such Substitute Mortgage
Loan conforms to the requirements set forth in the definition of "Substitute
Mortgage Loan" in the Mortgage Loan Purchase Agreement or this Agreement, as
applicable; provided, however, that substitution pursuant to the Mortgage Loan
Purchase Agreement or Section 2.04 of this Agreement, as applicable, in lieu of
purchase shall not

                                      -31-

<PAGE>

be permitted after the termination of the two-year period beginning on the
Startup Day; provided, further, that if the breach would cause the Mortgage Loan
to be other than a "qualified mortgage" as defined in Section 860G(a)(3) of the
Code, any such cure or substitution must occur within 90 days from the date the
breach was discovered. The Trustee or the Custodian, as its agent, shall examine
the Mortgage File for any Substitute Mortgage Loan in the manner set forth in
Section 2.02(a) and the Trustee or the Custodian, as its agent, shall notify the
Mortgage Loan Seller, in writing, within five Business Days after receipt,
whether or not the documents relating to the Substitute Mortgage Loan satisfy
the requirements of the fourth sentence of Subsection 2.02(a). Within two
Business Days after such notification, the Mortgage Loan Seller shall provide to
the Trustee for deposit in the Distribution Account the amount, if any, by which
the Outstanding Principal Balance as of the next preceding Due Date of the
Mortgage Loan for which substitution is being made, after giving effect to
Scheduled Principal due on such date, exceeds the Outstanding Principal Balance
as of such date of the Substitute Mortgage Loan, after giving effect to
Scheduled Principal due on such date, which amount shall be treated for the
purposes of this Agreement as if it were the payment by the Mortgage Loan Seller
of the Repurchase Price for the purchase of a Mortgage Loan by the Mortgage Loan
Seller. After such notification to the Mortgage Loan Seller and, if any such
excess exists, upon receipt of such deposit, the Trustee shall accept such
Substitute Mortgage Loan which shall thereafter be deemed to be a Mortgage Loan
hereunder. In the event of such a substitution, accrued interest on the
Substitute Mortgage Loan for the month in which the substitution occurs and any
Principal Prepayments made thereon during such month shall be the property of
the Trust Fund and accrued interest for such month on the Mortgage Loan for
which the substitution is made and any Principal Prepayments made thereon during
such month shall be the property of the Mortgage Loan Seller. The Scheduled
Principal on a Substitute Mortgage Loan due on the Due Date in the month of
substitution shall be the property of the Mortgage Loan Seller and the Scheduled
Principal on the Mortgage Loan for which the substitution is made due on such
Due Date shall be the property of the Trust Fund. Upon acceptance of the
Substitute Mortgage Loan (and delivery to the Trustee or Custodian of a Request
for Release for such Mortgage Loan), the Trustee shall release to the Mortgage
Loan Seller the related Mortgage File related to any Mortgage Loan released
pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of this
Agreement, as applicable, and shall execute and deliver all instruments of
transfer or assignment, without recourse, in form as provided to it as are
necessary to vest in the Mortgage Loan Seller title to and rights under any
Mortgage Loan released pursuant to the Mortgage Loan Purchase Agreement or
Section 2.04 of this Agreement, as applicable. The Mortgage Loan Seller shall
deliver the documents related to the Substitute Mortgage Loan in accordance with
the provisions of the Mortgage Loan Purchase Agreement or Subsections 2.01(b)
and 2.02(b) of this Agreement, as applicable, with the date of acceptance of the
Substitute Mortgage Loan deemed to be the Closing Date for purposes of the time
periods set forth in those Subsections. The representations and warranties set
forth in the Mortgage Loan Purchase Agreement shall be deemed to have been made
by the Mortgage Loan Seller with respect to each Substitute Mortgage Loan as of
the date of acceptance of such Mortgage Loan by the Trustee. The Trustee shall
amend the Mortgage Loan Schedule to reflect such substitution and shall provide
a copy of such amended Mortgage Loan Schedule to the Trustee and the Rating
Agencies.

         Section 2.05 ISSUANCE OF CERTIFICATES. The Trustee acknowledges the
assignment to it of the Mortgage Loans and the other assets comprising the Trust
Fund and, concurrently therewith, has signed, and countersigned and delivered to
the Seller, in exchange therefor, Certificates in such authorized denominations
representing such Fractional Undivided Interests as the Seller has requested.
The Trustee agrees that it will hold the Mortgage Loans and such other assets as
may from time to time be delivered to it segregated on the books of the Trustee
in trust for the benefit of the Certificateholders.

         The Seller, concurrently with the execution and delivery hereof, does
hereby transfer, assign, set over and otherwise convey in trust to the Trustee
without recourse all the right, title and interest of the Seller in and to the
REMIC I Regular Interests and the other assets of REMIC II for the benefit of
the holders of the REMIC II Certificates. The Trustee acknowledges receipt of
the REMIC I Regular Interests (which are uncertificated) and the other assets of

                 Administration and Servicing of Mortgage Loans

         Section 3.01 MASTER SERVICER. (a) The Master Servicer shall supervise,
monitor and oversee the obligation of the Servicer to service and administer the
Mortgage Loans in accordance with the terms of the Servicing Agreement and shall
have full power and authority to do any and all things which it may deem
necessary or desirable in connection with such master servicing and
administration. In performing its obligations hereunder, the Master Servicer
shall act in a manner consistent with Accepted Master Servicing Practices.
Furthermore, the Master Servicer shall oversee and consult with the Servicer as
necessary from time-to-time to carry out the Master Servicer's obligations
hereunder, shall receive, review and evaluate all reports, information and other
data provided to the Master Servicer by the Servicer and shall cause the
Servicer to perform and observe the covenants, obligations and conditions to be
performed or observed by the Servicer under the Servicing Agreement. The Master
Servicer shall independently and separately monitor the Servicer servicing
activities with respect to each Mortgage Loan, reconcile the results of such
monitoring with such information provided in the previous sentence on a monthly
basis and coordinate corrective adjustments to the Servicers' and Master
Servicers' records, and based on such reconciled and corrected information, the
Master Servicer shall provide such information to the Securities Administrator
as shall be necessary in order for it to prepare the statements specified in
Section 6.04 and any other information and statements required hereunder. The
Master Servicer shall reconcile the results of its Mortgage Loan monitoring with
the actual remittances of the Servicer to the Protected Account pursuant to the
applicable Servicing Agreements.

         (b) The Trustee shall furnish the Servicer and the Master Servicer with
any powers of attorney and other documents in form as provided to it necessary
or appropriate to enable the Servicer and the Master Servicer to service and
administer the related Mortgage Loans and REO Property.

         (c) The Trustee shall provide access to the records and documentation
in possession of the Trustee regarding the related Mortgage Loans and REO
Property and the servicing thereof to the Certificateholders, the FDIC, and the
supervisory agents and examiners of the FDIC, such access being afforded only
upon reasonable prior written request and during normal business hours at the
office of the Trustee; provided, however, that, unless otherwise required by
law, the Trustee shall not be required to provide access to such records and
documentation if the provision thereof would violate the legal right to privacy
of any Mortgagor. The Trustee shall allow representatives of the above entities
to photocopy any of the records and documentation and shall provide equipment
for that purpose at a charge that covers the Trustee's actual costs.

         (d) The Trustee shall execute and deliver to the Servicer and the
Master Servicer any court pleadings, requests for trustee's sale or other
documents necessary or desirable to (i) the foreclosure or trustee's sale with
respect to a Mortgaged Property; (ii) any legal action brought to obtain

other rights or remedies provided by the Mortgage Note or Security Instrument or
otherwise available at law or equity.

         Section 3.02 REMIC-RELATED COVENANTS. For as long as each REMIC shall
exist, the Trustee and the Securities Administrator shall act in accordance
herewith to assure continuing treatment of such REMIC as a REMIC, and the
Trustee and the Securities Administrator shall comply with any directions of the
Seller, the Servicer or the Master Servicer to assure such continuing treatment.
In particular, the Trustee shall not (a) sell or permit the sale of all or any
portion of the Mortgage Loans or of any investment of deposits in an Account
unless such sale is as a result of a repurchase of the Mortgage Loans pursuant
to this Agreement or the Trustee has received a REMIC Opinion prepared at the
expense of the Trust Fund; and (b) other than with respect to a substitution
pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of this
Agreement, as applicable, accept any contribution to any REMIC after the Startup
Day without receipt of a REMIC Opinion.

         Section 3.03 MONITORING OF SERVICER. (a) The Master Servicer shall be
responsible for reporting to the Trustee and the Seller the compliance by the
Servicer with its duties under the related Servicing Agreement. In the review of
the Servicer activities, the Master Servicer may rely upon an officer's
certificate of the Servicer with regard to the Servicer's compliance with the
terms of the Servicing Agreement. In the event that the Master Servicer, in its
judgment, determines that the Servicer should be terminated in accordance with
the Servicing Agreement, or that a notice should be sent pursuant to the
Servicing Agreement with respect to the occurrence of an event that, unless
cured, would constitute grounds for such termination, the Master Servicer shall
notify the Seller and the Trustee thereof and the Master Servicer shall issue
such notice or take such other action as it deems appropriate.

         (b) The Master Servicer, for the benefit of the Trustee and the
Certificateholders, shall enforce the obligations of the Servicer under the
Servicing Agreement, and shall, in the event that the Servicer fails to perform
its obligations in accordance with the Servicing Agreement, subject to the
preceding paragraph, terminate the rights and obligations of the Servicer
thereunder and act as servicer of the Mortgage Loans or to cause the Trustee to
enter in to a new Servicing Agreement with a successor Servicer selected by the
Master Servicer; provided, however, it is understood and acknowledged by the
parties hereto that there will be a period of transition (not to exceed 90 days)
before the actual servicing functions can be fully transferred to such successor
Servicer. Such enforcement, including, without limitation, the legal prosecution
of claims, termination of Servicing Agreement and the pursuit of other
appropriate remedies, shall be in such form and carried out to such an extent
and at such time as the Master Servicer, in its good faith business judgment,
would require were it the owner of the related Mortgage Loans. The Master
Servicer shall pay the costs of such enforcement at its own expense, provided
that the Master Servicer shall not be required to prosecute or defend any legal
action except to the extent that the Master Servicer shall have received
reasonable indemnity for its costs and expenses in pursuing such action.

         (c) To the extent that the costs and expenses of the Master Servicer
related to any termination of the Servicer , appointment of the successor
Servicer or the transfer and assumption of servicing by the Master Servicer with
respect to the Servicing Agreement (including, without limitation, (i) all legal
costs and expenses and all due diligence costs and expenses associated with an
evaluation of the potential termination of the Servicer as a result of an event
of default by the Servicer and (ii) all costs and expenses associated with the
complete transfer of servicing, including all servicing files and all servicing
data and the completion, correction or manipulation of such

                                      -36-

<PAGE>

servicing data as may be required by the successor servicer to correct any
errors or insufficiencies in the servicing data or otherwise to enable the
successor service to service the Mortgage Loans in accordance with the related
Servicing Agreement) are not fully and timely reimbursed by the terminated
Servicer, the Master Servicer shall be entitled to reimbursement of such costs
and expenses from the Distribution Account.

         The Master Servicer shall require the Servicer to comply with the
remittance requirements and other obligations set forth in the Servicing
Agreement.

         If the Master Servicer acts as Servicer, it will not assume liability
for the representations and warranties of the Servicer, if any, that it
replaces.

         Section 3.04 FIDELITY BOND. The Master Servicer, at its expense, shall
maintain in effect a blanket fidelity bond and an errors and omissions insurance
policy, affording coverage with respect to all directors, officers, employees
and other Persons acting on such Master Servicer's behalf, and covering errors
and omissions in the performance of the Master Servicer's obligations hereunder.
The errors and omissions insurance policy and the fidelity bond shall be in such
form and amount generally acceptable for entities serving as master servicers or
trustees.

         Section 3.05 POWER TO ACT; PROCEDURES. The Master Servicer shall master
service the Mortgage Loans and shall have full power and authority, subject to
the REMIC Provisions and the provisions of Article X hereof, to do any and all
things that it may deem necessary or desirable in connection with the master
servicing and administration of the Mortgage Loans, including but not limited to
the power and authority (i) to execute and deliver, on behalf of the
Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents, (ii) to consent to transfers of any Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages, (iii) to
collect any Insurance Proceeds and Liquidation Proceeds, and (iv) to effectuate
foreclosure or other conversion of the ownership of the Mortgaged Property
securing any Mortgage Loan, in each case, in accordance with the provisions of
this Agreement and the Servicing Agreement, as applicable; provided, however,
that the Master Servicer shall not (and, consistent with its responsibilities
under Section 3.03, shall not permit the Servicer to) knowingly or intentionally
take any action, or fail to take (or fail to cause to be taken) any action
reasonably within its control and the scope of duties more specifically set
forth herein, that, under the REMIC Provisions, if taken or not taken, as the
case may be, would cause REMIC I or REMIC II to fail to qualify as a REMIC or
result in the imposition of a tax upon the Trust Fund (including but not limited
to the tax on prohibited transactions as defined in Section 860F(a)(2) of the
Code and the tax on contributions to a REMIC set forth in Section 860G(d) of the
Code) unless the Master Servicer has received an Opinion of Counsel (but not at
the expense of the Master Servicer) to the effect that the contemplated action
will not would cause REMIC I or REMIC II to fail to qualify as a REMIC or result
in the imposition of a tax upon REMIC I or REMIC II, as the case may be. The
Trustee shall furnish the Master Servicer, upon written request from a Servicing
Officer, with any powers of attorney empowering the Master Servicer or the
Servicerto execute and deliver instruments of satisfaction or cancellation, or
of partial or full release or discharge, and to foreclose upon or otherwise
liquidate Mortgaged Property, and to appeal, prosecute or defend in any court
action relating to the Mortgage Loans or the Mortgaged Property, in accordance
with the Servicing Agreement and this Agreement, and the Trustee shall execute
and deliver such other documents, as the Master Servicer may request,

                                      -37-

<PAGE>

to enable the Master Servicer to master service and administer the Mortgage
Loans and carry out its duties hereunder, in each case in accordance with
Accepted Master Servicing Practices (and the Trustee shall have no liability for
misuse of any such powers of attorney by the Master Servicer or any Servicer).
If the Master Servicer or the Trustee has been advised that it is likely that
the laws of the state in which action is to be taken prohibit such action if
taken in the name of the Trustee or that the Trustee would be adversely affected
under the "doing business" or tax laws of such state if such action is taken in
its name, the Master Servicer shall join with the Trustee in the appointment of
a co-trustee pursuant to Section 9.11 hereof. In the performance of its duties
hereunder, the Master Servicer shall be an independent contractor and shall not,
except in those instances where it is taking action in the name of the Trustee,
be deemed to be the agent of the Trustee.

         Section 3.06 DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS. To the extent
provided in the Servicing Agreement, to the extent Mortgage Loans contain
enforceable due-on-sale clauses, the Master Servicer shall cause the Servicer to
enforce such clauses in accordance with the Servicing Agreement. If applicable
law prohibits the enforcement of a due-on-sale clause or such clause is
otherwise not enforced in accordance with the Servicing Agreement, and, as a
consequence, a Mortgage Loan is assumed, the original Mortgagor may be released
from liability in accordance with the Servicing Agreement.

         Section 3.07 RELEASE OF MORTGAGE FILES. (a) Upon becoming aware of the
payment in full of any Mortgage Loan, or the receipt by the Servicerof a
notification that payment in full has been escrowed in a manner customary for
such purposes for payment to Certificateholders on the next Distribution Date,
the Servicer will, if required under the Servicing Agreement, promptly furnish
to the Custodian, on behalf of the Trustee, two copies of a certification
substantially in the form of Exhibit D hereto signed by a Servicing Officer or
in a mutually agreeable electronic format which will, in lieu of a signature on
its face, originate from a Servicing Officer (which certification shall include
a statement to the effect that all amounts received in connection with such
payment that are required to be deposited in the Protected Account maintained by
the Servicer pursuant to Section 4.01 or by the Servicer pursuant to the
ServicingAgreement have been or will be so deposited) and shall request that the
Custodian, on behalf of the Trustee, deliver to the Servicer the related
Mortgage File. Upon receipt of such certification and request, the Custodian, on
behalf of the Trustee, shall promptly release the related Mortgage File to the
Servicer and the Trustee and Custodian shall have no further responsibility with
regard to such Mortgage File. Upon any such payment in full, the Servicer is
authorized, to give, as agent for the Trustee, as the mortgagee under the
Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or
assignment of mortgage without recourse) regarding the Mortgaged Property
subject to the Mortgage, which instrument of satisfaction or assignment, as the
case may be, shall be delivered to the Person or Persons entitled thereto
against receipt therefor of such payment, it being understood and agreed that no
expenses incurred in connection with such instrument of satisfaction or
assignment, as the case may be, shall be chargeable to the Protected Account.

         From time to time and as appropriate for the servicing or foreclosure
of any Mortgage Loan and in accordance with the Servicing Agreement, the Trustee
shall execute such documents as shall be prepared and furnished to the Trustee
by the Servicer or the Master Servicer (in form reasonably acceptable to the
Trustee) and as are necessary to the prosecution of any such proceedings. The
Custodian, on behalf of the Trustee, shall, upon the request of the Servicer or
the Master Servicer,

                                      -38-

<PAGE>

and delivery to the Custodian, on behalf of the Trustee, of two copies of a
request for release signed by a Servicing Officer substantially in the form of
Exhibit D (or in a mutually agreeable electronic format which will, in lieu of a
signature on its face, originate from a Servicing Officer), release the related
Mortgage File held in its possession or control to the Servicer or the Master
Servicer, as applicable. Such trust receipt shall obligate the Servicer or the
Master Servicer to return the Mortgage File to the Custodian on behalf of the
Trustee, when the need therefor by the Servicer or the Master Servicer no longer
exists unless the Mortgage Loan shall be liquidated, in which case, upon receipt
of a certificate of a Servicing Officer similar to that hereinabove specified,
the Mortgage File shall be released by the Custodian, on behalf of the Trustee,
to the Servicer or the Master Servicer.

         Section 3.08 DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF MASTER
SERVICER TO BE HELD FOR TRUSTEE.

         The Master Servicer shall transmit and the Servicer (to the extent
required by the Servicing Agreement) shall transmit to the Trustee or Custodian
such documents and instruments coming into the possession of the Master Servicer
or the Servicer from time to time as are required by the terms hereof, or in the
case of the Servicer, the Servicing Agreement, to be delivered to the Trustee or
Custodian. Any funds received by the Master Servicer or by the Servicer in
respect of any Mortgage Loan or which otherwise are collected by the Master
Servicer or by the Servicer as Liquidation Proceeds or Insurance Proceeds in
respect of any Mortgage Loan shall be held for the benefit of the Trustee and
the Certificateholders subject to the Master Servicer's right to reimbursement
from the Distribution Account the Master Servicing Compensation and other
amounts provided in this Agreement, and to the right of the Servicer to retain
the Servicing Fee and other amounts as provided in the Servicing Agreement. The
Master Servicer shall, and (to the extent provided in the Servicing Agreement)
shall cause the Servicer to, provide access to information and documentation
regarding the Mortgage Loans to the Trustee, its agents and accountants at any
time upon reasonable request and during normal business hours, and to
Certificateholders that are savings and loan associations, banks or insurance
companies, the Office of Thrift Supervision, the FDIC and the supervisory agents
and examiners of such Office and Corporation or examiners of any other federal
or state banking or insurance regulatory authority if so required by applicable
regulations of the Office of Thrift Supervision or other regulatory authority,
such access to be afforded without charge but only upon reasonable request in
writing and during normal business hours at the offices of the Master Servicer
designated by it. In fulfilling such a request the Master Servicer shall not be
responsible for determining the sufficiency of such information.

         All Mortgage Files and funds collected or held by, or under the control
of, the Master Servicer, in respect of any Mortgage Loans, whether from the
collection of principal and interest payments or from Liquidation Proceeds or
Insurance Proceeds, shall be held by the Master Servicer for and on behalf of
the Trustee and the Certificateholders and shall be and remain the sole and
exclusive property of the Trustee; provided, however, that the Master Servicer
and the Servicer shall be entitled to setoff against, and deduct from, any such
funds any amounts that are properly due and payable to the Master Servicer or
the Servicerunder this Agreement or the Servicing Agreement.

obligation of the Servicer under the related Servicing Agreements to maintain or
cause to be maintained standard fire and casualty insurance and, where
applicable, flood insurance, all in accordance with the provisions of the
related Servicing Agreements. It is understood and agreed that such insurance
shall be with insurers meeting the eligibility requirements set forth in the
Servicing Agreement and that no earthquake or other additional insurance is to
be required of any Mortgagor or to be maintained on property acquired in respect
of a defaulted loan, other than pursuant to such applicable laws and regulations
as shall at any time be in force and as shall require such additional insurance.

         Pursuant to Section 4.01 and 4.02, any amounts collected by the
Servicer or the Master Servicer, or by any Servicer, under any insurance
policies (other than amounts to be applied to the restoration or repair of the
property subject to the related Mortgage or released to the Mortgagor in
accordance with the Servicing Agreement) shall be remitted to the Trustee for
deposit into the Distribution Account, subject to withdrawal pursuant to Section
4.02 and 4.03. Any cost incurred by the Master Servicer or the Servicerin
maintaining any such insurance if the Mortgagor defaults in its obligation to do
so shall be added to the amount owing under the Mortgage Loan where the terms of
the Mortgage Loan so permit; provided, however, that the addition of any such
cost shall not be taken into account for purposes of calculating the
distributions to be made to Certificateholders and shall be recoverable by the
Master Servicer or the Servicerpursuant to Section 4.02 and 4.03.

         Section 3.10 PRESENTMENT OF CLAIMS AND COLLECTION OF PROCEEDS. The
Master Servicer shall (to the extent provided in the Servicing Agreement) cause
the Servicer to, prepare and present on behalf of the Trustee and the
Certificateholders all claims under the Insurance Policies and take such actions

insured's claim) as shall be necessary to realize recovery under such policies.

remitted to the Master Servicer) in respect of such policies, bonds or contracts
shall be remitted to the Trustee for deposit in the Distribution Account upon

or restoration of the related Mortgaged Property as a condition precedent to the
presentation of claims on the related Mortgage Loan to the insurer under any
applicable Insurance Policy need not be so deposited (or remitted).

         Section 3.11 MAINTENANCE OF THE PRIMARY MORTGAGE INSURANCE POLICIES.

         The Master Servicer shall not take, or permit the Servicer(to the
extent such action is prohibited under the Servicing Agreement) to take, any
action that would result in noncoverage under any applicable Primary Mortgage
Insurance Policy of any loss which, but for the actions of such Master Servicer
or Servicer, would have been covered thereunder. The Master Servicer shall use
its best reasonable efforts to cause the Servicer (to the extent required under
the related Servicing Agreement) to keep in force and effect (to the extent that
the Mortgage Loan requires the Mortgagor to maintain such insurance), primary
mortgage insurance applicable to each Mortgage Loan in accordance with the
provisions of this Agreement and the related Servicing Agreement, as applicable.
The Master Servicer shall not, and shall not permit the Servicer(to the extent
required

                                      -40-

Primary Mortgage Insurance Policy that is in effect at the date of the initial
issuance of the Mortgage Note and is required to be kept in force hereunder
except in accordance with the provisions of this Agreement and the related
Servicing Agreement, as applicable.

         The Master Servicer agrees to present, or to cause the Servicer (to the
extent required under the related Servicing Agreement) to present, on behalf of
the Trustee and the Certificateholders, claims to the insurer under any Primary
Mortgage Insurance Policies and, in this regard, to take such reasonable action
as shall be necessary to permit recovery under any Primary Mortgage Insurance
Policies respecting defaulted Mortgage Loans. Pursuant to Section 4.01 and 4.02,
any amounts collected by the Master Servicer or the Servicerunder any Primary
Mortgage Insurance Policies shall be remitted to the Trustee for deposit in the
Distribution Account, subject to withdrawal pursuant to Section 4.02 or 4.03.

         Section 3.12 TRUSTEE TO RETAIN POSSESSION OF CERTAIN INSURANCE POLICIES
AND DOCUMENTS.

         The Trustee (or the Custodian, as directed by the Trustee), shall
retain possession and custody of the originals (to the extent available) of any
Primary Mortgage Insurance Policies, or certificate of insurance if applicable,
and any certificates of renewal as to the foregoing as may be issued from time
to time as contemplated by this Agreement. Until all amounts distributable in
respect of the Certificates have been distributed in full and the Master
Servicer otherwise has fulfilled its obligations under this Agreement, the
Trustee (or its Custodian, if any, as directed by the Trustee) shall also retain
possession and custody of each Mortgage File in accordance with and subject to
the terms and conditions of this Agreement. The Master Servicer shall promptly
deliver or cause to be delivered to the Trustee (or the Custodian, as directed
by the Trustee), upon the execution or receipt thereof the originals of any

arrangements can be made for collection of delinquent payments, all in

activities hereunder. Servicing compensation in the form of assumption fees, if
any, late payment charges, as collected, if any, or otherwise (but not including
any prepayment premium or penalty) shall be retained by the applicable Servicer

entitled to retain, as additional compensation, any interest remitted by a
Servicer in connection with a Principal Prepayment in full or otherwise in
excess of amounts

be required to pay all expenses incurred by it in connection with its activities
hereunder and shall not be entitled to reimbursement therefor except as provided
in this Agreement.

         Section 3.15 REO PROPERTY.

         In the event the Trust Fund acquires ownership of any REO Property in
respect of any related Mortgage Loan, the deed or certificate of sale shall be
issued to the Trustee, or to its nominee, on behalf of the related
Certificateholders. The Master Servicer shall, to the extent provided in the
Servicing Agreement, cause the applicable Servicer to sell, any REO Property as
expeditiously as possible and in accordance with the provisions of this
Agreement and the related Servicing Agreement, as applicable. Pursuant to its
efforts to sell such REO Property, the Master Servicer shall cause the
applicable Servicer to protect and conserve, such REO Property in the manner and
to the extent required by the Servicing Agreement, in accordance with the REMIC
Provisions and in a manner that does not result in a tax on "net income from
foreclosure property" or cause such REO Property to fail to qualify as
"foreclosure property" within the meaning of Section 860G(a)(8) of the Code.

         The Master Servicer shall, to the extent required by the related
Servicing Agreement, cause the applicable Servicer to deposit all funds
collected and received in connection with the operation of any REO Property in

disposition of any REO Property, shall be entitled to reimbursement for any
related unreimbursed Monthly Advances and other unreimbursed advances as well as
any unpaid Servicing Fees from Liquidation Proceeds received in connection with
the final disposition of such REO Property; provided, that any such unreimbursed
Monthly Advances as well as any unpaid Servicing Fees may be reimbursed or paid,
as the case may be, prior to final disposition, out of any net rental income or
other net amounts derived from such REO Property.

         To the extent provided in the related Servicing Agreement, the
Liquidation Proceeds from the final disposition of the REO Property, net of any
payment to the Master Servicer and the applicable Servicer as provided above
shall be deposited in the Protected Account on or prior to the Determination
Date in the month following receipt thereof and be remitted by wire transfer in
immediately available funds to the Trustee for deposit into the related
Distribution Account on the next succeeding Servicer Remittance Date.

         The Master Servicer shall deliver to the Trustee and the Rating
Agencies on or before May 31 of each year, commencing on May 31, 2003, an

December 31 of the prior year: (i) such Servicing Officer has reviewed the
activities of such Master Servicer during the preceding calendar year or portion
thereof and its performance under this Agreement, (ii) to the best of such
Servicing Officer's knowledge, based on such review, such Master Servicer has
performed and fulfilled its duties, responsibilities and obligations under this

                                      -42-

<PAGE>

a default in the fulfillment of any such duties, responsibilities or
obligations, specifying each such default known to such Servicing Officer and
the nature and status thereof, (iii) nothing has come to the attention of such
Servicing Officer to lead such Servicing Officer to believe that the Servicerhas
failed to perform any of its duties, responsibilities and obligations under the
ServicingAgreement in all material respects throughout such year, or, if there
has been a material default in the performance or fulfillment of any such
duties, responsibilities or obligations, specifying each such default known to
such Servicing Officer and the nature and status thereof.

         Copies of such statements shall be provided to any Certificateholder
upon request, by the Master Servicer or by the Trustee at the Master Servicer's
expense if the Master Servicer failed to provide such copies (unless (i) the
Master Servicer shall have failed to provide the Trustee with such statement or
(ii) the Trustee shall be unaware of the Master Servicer's failure to provide
such statement).

         Section 3.17 ANNUAL INDEPENDENT ACCOUNTANT'S SERVICING REPORT. If the
Master Servicer has, during the course of any fiscal year, directly serviced any
of the Mortgage Loans, then the Master Servicer at its expense shall cause a
nationally recognized firm of independent certified public accountants to
furnish a statement to the Trustee, the Rating Agencies and the Seller on or
before May 31 of each year, commencing on May 31, 2003 to the effect that, with
respect to the most recently ended fiscal year, such firm has examined certain
records and documents relating to the Master Servicer's performance of its
servicing obligations under this Agreement and pooling and servicing and trust
agreements in material respects similar to this Agreement and to each other and
that, on the basis of such examination conducted substantially in compliance
with the audit program for mortgages serviced for Freddie Mac or the Uniform
Single Attestation Program for Mortgage Bankers, such firm is of the opinion
that the Master Servicer's activities have been conducted in compliance with
this Agreement, or that such examination has disclosed no material items of
noncompliance except for (i) such exceptions as such firm believes to be
immaterial, (ii) such other exceptions as are set forth in such statement and
(iii) such exceptions that the Uniform Single Attestation Program for Mortgage
Bankers or the Audit Program for Mortgages Serviced by Freddie Mac requires it
to report. Copies of such statements shall be provided to any Certificateholder
upon request by the Master Servicer, or by the Trustee at the expense of the
Master Servicer if the Master Servicer shall fail to provide such copies. If
such report discloses exceptions that are material, the Master Servicer shall
advise the Trustee whether such exceptions have been or are susceptible of cure,
and will take prompt action to do so.

         Section 3.18 REPORTS FILED WITH SECURITIES AND EXCHANGE COMMISSION.
Within 15 days after each Distribution Date, the Securities Administrator shall,
in accordance with industry standards, file with the Commission via the
Electronic Data Gathering and Retrieval System ("EDGAR"), a Form 8-K with a copy
of the statement to the Trustee who shall furnish a copy of the statement to the
Certificateholders for such Distribution Date as an exhibit thereto. Prior to
January 30, 2003, the Securities Administrator shall, in accordance with
industry standards and only if instructed by the Seller, file a Form 15
Suspension Notice with respect to the Trust Fund, if applicable. Prior to March
30, 2003, the Securities Administrator shall file a Form 10-K, in substance
conforming to industry standards, with respect to the Trust Fund. The Seller
hereby grants to the Securities Administrator a limited power of attorney to
execute and file each such document on behalf of the Seller. Such power of
attorney shall continue until either the earlier of (i) receipt by the
Securities Administrator

                                      -43-

<PAGE>

from the Seller of written termination of such power of attorney and (ii) the
termination of the Trust Fund. The Seller agrees to promptly furnish to the
Securities Administrator, from time to time upon request, such further
information, reports and financial statements within its control related to this
Agreement and the Mortgage Loans as the Securities Administrator reasonably
deems appropriate to prepare and file all necessary reports with the Commission.
The Securities Administrator shall have no responsibility to file any items
other than those specified in this Section 3.18; provided, however, the
Securities Administrator will cooperate with the Seller in connection with any
additional filings with respect to the Trust Fund as the Seller deems necessary
under the Securities Exchange Act of 1934, as amended (the "Exchange Act").
Copies of all reports filed by the Securities Administrator under the Exchange
Act shall be sent to: the Seller c/o Bear, Stearns & Co. Inc., Attn: Managing
Director-Analysis and Control, One Metrotech Center North, Brooklyn, New York
11202- 3859. Fees and expenses incurred by the Securities Administrator in
connection with this Section 3.18 shall not be reimbursable from the Trust Fund.

         Section 3.19 EMC. On the Closing Date, EMC will receive from the Seller
a payment of $5,000.

         Section 3.20 UCC. The Trustee agrees to file continuation statements
for any Uniform Commercial Code financing statements which the Seller has
informed the Trustee were filed on the Closing Date in connection with the
Trust. The Seller shall file any financing statements or amendments thereto
required by any change in the Uniform Commercial Code.

         Section 3.21 OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS.

         With respect to any Mortgage Loan which as of the first day of a
Calendar Quarter is delinquent in payment by 90 days or more or is an REO
Property, EMC shall have the right to purchase such Mortgage Loan from the Trust
at a price equal to the Repurchase Price; provided however (i) that such
Mortgage Loan is still 90 days or more delinquent or is an REO Property as of
the date of such purchase and (ii) this purchase option, if not theretofore
exercised, shall terminate on the date prior to the last day of the related
Calendar Quarter. This purchase option, if not exercised, shall not be
thereafter reinstated unless the delinquency is cured and the Mortgage Loan
thereafter again becomes 90 days or more delinquent or becomes an REO Property,
in which case the option shall again become exercisable as of the first day of
the related Calendar Quarter.

         If at any time EMC remits to the Trustee a payment for deposit in the
Distribution Account covering the amount of the Repurchase Price for such a
Mortgage Loan, and EMC provides to the Trustee a certification signed by a
Servicing Officer stating that the amount of such payment has been deposited in
the Distribution Account, then the Trustee shall execute the assignment of such
Mortgage Loan at the request of EMC without recourse to EMC which shall succeed
to all the Trustee's right, title and interest in and to such Mortgage Loan, and
all security and documents relative thereto. Such assignment shall be an
assignment outright and not for security. EMC will thereupon own such Mortgage,
and all such security and documents, free of any further obligation to the
Trustee or the Certificateholders with respect thereto.

Agreement) of receipt all collections of principal and interest on any Mortgage
Loan and with respect to any REO Property received by the Servicer , including
Principal Prepayments, Insurance Proceeds, Liquidation Proceeds, and advances
made from the Servicer's own funds (less servicing compensation as permitted by

to the related Protected Account for purposes required or permitted by this

Certificateholders resulting from such investments shall be borne by and be the
risk of the Servicer. The Servicer (to the extent provided in the Servicing
Agreement) shall deposit the amount of any such loss in the Protected Account
within two Business Days of receipt of notification of such loss but not later
than the second Business Day prior to the Distribution Date on which the moneys
so invested are required to be distributed to the Certificateholders.

         (c) To the extent provided in the Servicing Agreement and subject to
this Article IV, on or before the Servicer Remittance Date, the Servicer shall
withdraw or shall cause to be withdrawn from the Protected Accounts and shall
immediately deposit or cause to be deposited in the Distribution Account amounts
representing the following collections and payments (other than with respect to
principal of or interest on the Mortgage Loans due on or before the Cut-off
Date) with respect to each Loan Group:

         related portion thereof advanced by the Servicer pursuant to the
         Servicing Agreements which were due on or before the related Due Date,
         net of the amount thereof comprising the Servicing Fees;

                  (ii) Full Principal Prepayments and any Liquidation Proceeds

         comprising the Servicing Fees;

                  (iii) Partial Principal Prepayments received by the Servicer
         for such Mortgage Loans in the related Prepayment Period; and

                  (iv) Any amount to be used as an Advance.

         (d) Withdrawals may be made from an Account only to make remittances as
provided in Section 4.01(c), 4.02 and 4.03; to reimburse the Master Servicer or
the Servicer for Monthly Advances which have been recovered by subsequent
collection from the related Mortgagor; to remove amounts deposited in error; to
remove fees, charges or other such amounts deposited on a temporary basis; or to
clear and terminate the account at the termination of this Agreement in
accordance with Section 10.01. As provided in Sections 4.01(c) and 4.02(b)
certain amounts otherwise due to the Servicer may be retained by them and need
not be deposited in the Distribution Account.

         Section 4.02 DISTRIBUTION ACCOUNT. (a) The Trustee shall establish and
maintain in the name of the Trustee, for the benefit of the Certificateholders,
the Distribution Account as a segregated trust account or accounts.

         (b) All amounts deposited to the Distribution Account shall be held by
the Trustee in the name of the Trustee in trust for the benefit of the
Certificateholders in accordance with the terms and provisions of this
Agreement.

         (c) The Distribution Account shall constitute a trust account of the
Trust Fund segregated on the books of the Trustee and held by the Trustee in
trust in its Corporate Trust Office, and the Distribution Account and the funds
deposited therein shall not be subject to, and shall be protected from, all
claims, liens, and encumbrances of any creditors or depositors of the Trustee
(whether made directly, or indirectly through a liquidator or receiver of the
Trustee). The amount at any time credited to the Distribution Account shall be
invested in the name of the Trustee, in such Permitted Investments selected by
the Master Servicer or deposited in demand deposits with such depository
institutions as selected by the Master Servicer, provided that time deposits of
such depository institutions would be a Permitted Investment. All Permitted
Investments shall mature or be subject to redemption or withdrawal on or before,
and shall be held until, the next succeeding Distribution Date if the obligor
for such Permitted Investment is the Trustee or, if such obligor is any other
Person, the Business Day preceding such Distribution Date. All investment
earnings on amounts on deposit in the Distribution Account therein from time to
time shall be for the account of the Master Servicer. The Master Servicer shall
receive distribution of any and all investment earnings from the Distribution
Account on each Distribution Date. If there is any loss on a Permitted
Investment or demand deposit, the Master Servicer shall remit the amount of the
loss to the Trustee who shall deposit such amount in the Distribution Account.
With respect to the Distribution Account and the funds deposited therein, the
Trustee shall take such action as may be necessary to ensure that the
Certificateholders shall be entitled to the priorities afforded to such a trust
account (in addition to a claim against the estate of the Trustee) as provided
by 12 U.S.C. ss. 92a(e), and applicable

                                      -46-

                                  Certificates

         Section 5.01 CERTIFICATES. (a) The Depository, the Seller and the
Trustee have entered into a Depository Agreement dated as of the Closing Date
(the "Depository Agreement"). Except for the Residual Certificates, the Private
Certificates and the Individual Certificates and as provided in Subsection
5.01(b), the Certificates shall at all times remain registered in the name of
the Depository or its nominee and at all times: (i) registration of such
Certificates may not be transferred by the Trustee except to a successor to the
Depository; (ii) ownership and transfers of registration of such Certificates on
the books of the Depository shall be governed by applicable rules established by
the Depository; (iii) the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants; (iv) the Trustee shall
deal with the Depository as representative of such Certificate Owners of the
respective Class of Certificates for purposes of exercising the rights of
Certificateholders under this Agreement, and requests and directions for and
votes of such representative shall not be deemed to be inconsistent if they are
made with respect to different Certificate Owners; and (v) the Trustee may rely
and shall be fully protected in relying upon information furnished by the
Depository with respect to its Depository Participants.

         The Residual Certificates and the Private Certificates are initially
Physical Certificates. If at any time the Holders of all of the Certificates of
one or more such Classes request that the Trustee cause such Class to become
Global Certificates, the Trustee and the Seller will take such action as may be
reasonably required to cause the Depository to accept such Class or Classes for
trading if it may legally be so traded.

         All transfers by Certificate Owners of such respective Classes of
Book-Entry Certificates and any Global Certificates shall be made in accordance
with the procedures established by the Depository Participant or brokerage firm
representing such Certificate Owners. Each Depository Participant shall only
transfer Book-Entry Certificates of Certificate Owners it represents or of
brokerage firms for which it acts as agent in accordance with the Depository's
normal procedures.

         (b) If (i)(A) the Seller advises the Trustee in writing that the
Depository is no longer willing or able to properly discharge its
responsibilities as Depository and (B) the Trustee or the Seller is unable to
locate a qualified successor within 30 days or (ii) the Seller at its option
advises the Trustee in writing that it elects to terminate the book-entry system
through the Depository, the Trustee shall request that the Depository notify all
Certificate Owners of the occurrence of any such event and of the availability
of definitive, fully registered Certificates to Certificate Owners requesting
the same. Upon surrender to the Trustee of the Certificates by the Depository,
accompanied by registration instructions from the Depository for registration,
the Trustee shall issue the definitive Certificates. Neither the Seller nor the
Trustee shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.

         Interests (designated below), which will be uncertificated and
         non-transferable and are hereby designated as the "regular interests"
         in REMIC I and (y) the Class R-I Certificates, which is hereby
         designated as the single "residual interest" in REMIC I. Distributions
         of principal shall be deemed to be made from each Loan Group to the
         REMIC I Regular Interests in the Related Group (as defined and set
         forth in the chart below) first, to each REMIC I Regular Interest
         ending with the designation "SUB," so that the Uncertificated Principal
         Balance of each such REMIC I Regular Interest is equal to 0.01% of the
         excess of (x) the aggregate Scheduled Principal Balance of the Mortgage
         Loans in the Related Group over (y) the Current Principal Amount of the
         Senior Certificates in the Related Group (except that if any such
         excess is a larger number than in the preceding distribution period,
         the least amount of principal shall be distributed to such REMIC I
         Regular Interests such that the REMIC I Subordinated Balance Ratio is
         maintained); and (A) from remaining funds in the Loan Group 1,
         sequentially, to (i) REMIC I Regular Interests 1A1, 1A2-1, 1A2-2, 1A3
         and 1A4 with the amount to be distributed equal to the amount
         distributed to the Certificates with the same numerical and
         alphabetical designation, (ii) REMIC I Regular Interest 2A with the
         amount to be distributed equal to the amount distributed to the Class

         numerical and alphabetical designation, (ii) REMIC I Regular Interests
         1A1, 1A2-1, 1A2-2, 1A3 and 1A4 with the amount to be distributed equal
         to the amount distributed to the Certificates with the same numerical
         and alphabetical designation and (iii) REMIC I Regular Interest 2ZZ.
         Realized Losses shall be applied after all distributions have been made
         on each Distribution Date first, to each REMIC I Regular Interest
         ending with the designation "SUB," so that the Uncertificated Principal
         Balance of each such REMIC I Regular Interest is equal to 0.01% of the
         excess of (x) the aggregate Scheduled Principal Balance of the Mortgage
         Loans in the related Group over (y) the Current Principal Amount of the
         Senior Certificate in the Related Group (except that if any such excess

the Subordinate Certificates, $25,000 and increments of $1.00 in excess thereof,
except that one Certificate of each such Class may be issued in a different

such Class shall equal the Current Principal Amount of such Class on the Closing
Date. On the Closing Date, the Trustee shall execute and countersign Physical
Certificates all in an aggregate principal amount that shall equal the Current
Principal Amount of such Class on the Closing Date. The Residual Certificates
shall each be issued in certificated fully-registered form in the denomination
of $50 and $50, respectively. Each Class of Global Certificates, if any, shall
be issued in fully registered form in minimum dollar denominations of $50,000
and integral multiples of $1.00 in excess thereof, except that one Certificate
of each Class may be in a different denomination so that the sum of the
denominations of all outstanding Certificates of such Class shall equal the
Current Principal Amount of such Class on the Closing Date. On the Closing Date,
the Trustee shall execute and countersign (i) in the case of each Class of
Offered Certificates, the Certificate in the entire Current Principal Amount of
the respective Class and (ii) in the case of each Class of Private Certificates,
Individual Certificates all in an aggregate principal amount that shall equal
the Current Principal Amount of each such respective Class on the Closing Date.
The Certificates referred to in clause (i) and if at any time there are to be
Global Certificates, the Global Certificates shall be delivered by the Seller to
the Depository or pursuant to the Depository's instructions, shall be delivered
by the Seller on behalf of the Depository to and deposited with the DTC
Custodian. The Trustee shall sign the Certificates by facsimile or manual
signature and countersign them by manual signature on behalf of the Trustee by

authorized signatories of the Trustee or its agent at the time of issuance shall
bind the Trustee, notwithstanding that such individuals or any of them have
ceased to hold such positions prior to the delivery of such Certificate.

         (h) No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless there appears on such Certificate
the manually executed countersignature of the Trustee or its agent, and such
countersignature upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly executed and delivered hereunder.
All Certificates issued on the Closing Date shall be dated the Closing Date. All
Certificates issued thereafter shall be dated the date of their
countersignature.

         (i) The Closing Date is hereby designated as the "startup" day of each
REMIC within the meaning of Section 860G(a)(9) of the Code.

         (j) For federal income tax purposes, each REMIC shall have a tax year
that is a calendar year and shall report income on an accrual basis.

         (k) The Trustee on behalf of the Trust shall cause each REMIC to timely
elect to be treated as a REMIC under Section 860D of the Code. Any
inconsistencies or ambiguities in this Agreement or in the administration of any
Trust established hereby shall be resolved in a manner that preserves the
validity of such elections.

forth below, upon surrender for registration of transfer of any Certificate at
any office or agency of the Trustee maintained for such purpose, the Trustee
shall sign, countersign and shall deliver, in the name of the designated
transferee or transferees, a new Certificate of a like Class and aggregate
Fractional Undivided Interest, but bearing a different number.

         (c) By acceptance of an Individual Certificate, whether upon original

restrictions shall apply with respect to the transfer and registration of
transfer of an Individual Certificate to a transferee that takes delivery in the
form of an Individual Certificate:

                  (i) The Trustee shall register the transfer of an Individual
         Certificate if the requested transfer is being made to a transferee who

         evidence as to its QIB status.

                  (ii) The Trustee shall register the transfer of any Individual
         Certificate if (x) the transferor has advised the Trustee in writing
         that the Certificate is being transferred to an Institutional
         Accredited Investor; and (y) prior to the transfer the transferee
         furnishes to the Trustee an Investment Letter (and the Trustee shall be
         fully protected in so doing), provided that, if based upon an Opinion
         of Counsel to the effect that the delivery of (x) and (y) above are not
         sufficient to confirm that the proposed transfer is being made pursuant
         to an exemption from, or in a transaction not subject to, the
         registration requirements of the Securities Act and other applicable
         laws, the Trustee shall as a condition of the registration of any such
         transfer require the transferor to furnish such other certifications,
         legal opinions or other information prior to registering the transfer
         of an Individual Certificate as shall be set forth in such Opinion of
         Counsel.

         (d) Subject to Subsection 5.02(h), so long as a Global Certificate of
such Class is outstanding and is held by or on behalf of the Depository,
transfers of beneficial interests in such Global Certificate, or transfers by
holders of Individual Certificates of such Class to transferees that take
delivery in the form of beneficial interests in the Global Certificate, may be

         the form of an Individual Certificate or Certificates and the Trustee
         shall register such transfer only upon compliance with the provisions
         of Subsection 5.02(c)(ii).

                  (ii) In the case of a beneficial interest in a Class of Global
         Certificates being transferred to a transferee that takes delivery in
         the form of an Individual Certificate or Certificates of such Class,
         except as set forth in clause (i) above, the Trustee shall register
         such transfer only upon compliance with the provisions of Subsection
         5.02(c)(i).

                  (iii) In the case of an Individual Certificate of a Class
         being transferred to a transferee that takes delivery in the form of a
         beneficial interest in a Global Certificate of such Class, the Trustee
         shall register such transfer if the transferee has provided the Trustee
         with a Rule 144A Certificate or comparable evidence as to its QIB
         status.

                  (iv) No restrictions shall apply with respect to the transfer
         or registration of transfer of a beneficial interest in the Global
         Certificate of a Class to a transferee that takes delivery in the form
         of a beneficial interest in the Global Certificate of such Class;
         provided that each such transferee shall be deemed to have made such
         representations and warranties contained in the Rule 144A Certificate
         as are sufficient to establish that it is a QIB.

         (e) Subject to Subsection 5.02(h), an exchange of a beneficial interest
in a Global Certificate of a Class for an Individual Certificate or Certificates
of such Class, an exchange of an Individual Certificate or Certificates of a
Class for a beneficial interest in the Global Certificate of such Class and an
exchange of an Individual Certificate or Certificates of a Class for another
Individual Certificate or Certificates of such Class (in each case, whether or
not such exchange is made in anticipation of subsequent transfer, and, in the
case of the Global Certificate of such Class, so long as such Certificate is
outstanding and is held by or on behalf of the Depository) may be made only in
accordance with this Subsection 5.02(e) and in accordance with the rules of the
Depository:

                  (i) A holder of a beneficial interest in a Global Certificate
         of a Class may at any time exchange such beneficial interest for an
         Individual Certificate or Certificates of such Class.

                  (ii) A holder of an Individual Certificate or Certificates of
         a Class may exchange such Certificate or Certificates for a beneficial
         interest in the Global Certificate of such Class if such holder
         furnishes to the Trustee a Rule 144A Certificate or comparable evidence
         as to its QIB status.

                  (iii) A holder of an Individual Certificate of a Class may
         exchange such Certificate for an equal aggregate principal amount of
         Individual Certificates of such Class in different authorized
         denominations without any certification.

         (f)(i) Upon acceptance for exchange or transfer of an Individual
Certificate of a Class for a beneficial interest in a Global Certificate of such
Class as provided herein, the Trustee shall cancel such Individual Certificate
and shall (or shall request the Depository to) endorse on the schedule affixed
to the applicable Global Certificate (or on a continuation of such schedule
affixed to the Global Certificate and made a part thereof) or otherwise make in
its books and records an appropriate

                                      -56-

<PAGE>

notation evidencing the date of such exchange or transfer and an increase in the
certificate balance of the Global Certificate equal to the certificate balance
of such Individual Certificate exchanged or transferred therefor.

                  (ii) Upon acceptance for exchange or transfer of a beneficial
         interest in a Global Certificate of a Class for an Individual
         Certificate of such Class as provided herein, the Trustee shall (or
         shall request the Depository to) endorse on the schedule affixed to
         such Global Certificate (or on a continuation of such schedule affixed
         to such Global Certificate and made a part thereof) or otherwise make
         in its books and records an appropriate notation evidencing the date of
         such exchange or transfer and a decrease in the certificate balance of
         such Global Certificate equal to the certificate balance of such
         Individual Certificate issued in exchange therefor or upon transfer
         thereof.

         (g) The Securities Legend shall be placed on any Individual Certificate
issued in exchange for or upon transfer of another Individual Certificate or of
a beneficial interest in a Global Certificate.

         (h) Subject to the restrictions on transfer and exchange set forth in
this Section 5.02, the holder of any Individual Certificate may transfer or
exchange the same in whole or in part (in an initial certificate balance equal
to the minimum authorized denomination set forth in Section 5.01(h) above or any
integral multiple of $1.00 in excess thereof) by surrendering such Certificate
at the Corporate Trust Office, or at the office of any transfer agent, together
with an executed instrument of assignment and transfer satisfactory in form and
substance to the Trustee in the case of transfer and a written request for
exchange in the case of exchange. The holder of a beneficial interest in a
Global Certificate may, subject to the rules and procedures of the Depository,
cause the Depository (or its nominee) to notify the Trustee in writing of a
request for transfer or exchange of such beneficial interest for an Individual
Certificate or Certificates. Following a proper request for transfer or
exchange, the Trustee shall, within five Business Days of such request made at
such Corporate Trust Office, sign, countersign and deliver at such Corporate
Trust Office, to the transferee (in the case of transfer) or holder (in the case
of exchange) or send by first class mail at the risk of the transferee (in the
case of transfer) or holder (in the case of exchange) to such address as the
transferee or holder, as applicable, may request, an Individual Certificate or
Certificates, as the case may require, for a like aggregate Fractional Undivided
Interest and in such authorized denomination or denominations as may be
requested. The presentation for transfer or exchange of any Individual
Certificate shall not be valid unless made at the Corporate Trust Office by the
registered holder in person, or by a duly authorized attorney-in-fact.

         (i) At the option of the Certificateholders, Certificates may be
exchanged for other Certificates of authorized denominations of a like Class and
aggregate Fractional Undivided Interest, upon surrender of the Certificates to
be exchanged at any such office or agency; provided, however, that no
Certificate may be exchanged for new Certificates unless the original Fractional
Undivided Interest represented by each such new Certificate (i) is at least
equal to the minimum authorized denomination or (ii) is acceptable to the Seller
as indicated to the Trustee in writing. Whenever any Certificates are so
surrendered for exchange, the Trustee shall sign and countersign and the Trustee
shall deliver the Certificates which the Certificateholder making the exchange
is entitled to receive.

                                      -57-

<PAGE>

         (j) If the Trustee so requires, every Certificate presented or
surrendered for transfer or exchange shall be duly endorsed by, or be
accompanied by a written instrument of transfer, with a signature guarantee, in
form satisfactory to the Trustee, duly executed by the holder thereof or his or
her attorney duly authorized in writing.

         (k) No service charge shall be made for any transfer or exchange of
Certificates, but the Trustee may require payment of a sum sufficient to cover
any tax or governmental charge that may be imposed in connection with any
transfer or exchange of Certificates.

         (l) The Trustee shall cancel all Certificates surrendered for transfer
or exchange but shall retain such Certificates in accordance with its standard
retention policy or for such further time as is required by the record retention
requirements of the Securities Exchange Act of 1934, as amended, and thereafter
may destroy such Certificates.

         Section 5.03 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES. (a) If
(i) any mutilated Certificate is surrendered to the Trustee, or the Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and (ii) there is delivered to the Trustee such security or
indemnity as it may require to save it harmless, and (iii) the Trustee has not
received notice that such Certificate has been acquired by a third Person, the
Trustee shall sign, countersign and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and Fractional Undivided Interest but in each case bearing a different
number. The mutilated, destroyed, lost or stolen Certificate shall thereupon be
canceled of record by the Trustee and shall be of no further effect and evidence
no rights.

         (b) Upon the issuance of any new Certificate under this Section 5.03,
the Trustee may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
Any duplicate Certificate issued pursuant to this Section 5.03 shall constitute
complete and indefeasible evidence of ownership in the Trust Fund, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

         Section 5.04 PERSONS DEEMED OWNERS. Prior to due presentation of a
Certificate for registration of transfer, the Seller, the Trustee and any agent
of the Seller or the Trustee may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving
distributions pursuant to Section 6.01 and for all other purposes whatsoever.
Neither the Seller, the Trustee nor any agent of the Seller or the Trustee shall
be affected by notice to the contrary. No Certificate shall be deemed duly
presented for a transfer effective on any Record Date unless the Certificate to
be transferred is presented no later than the close of business on the third
Business Day preceding such Record Date.

         Section 5.05 TRANSFER RESTRICTIONS ON RESIDUAL CERTIFICATES. (a)
Residual Certificates, or interests therein, may not be transferred without the
prior express written consent of the Tax Matters Person and the Seller. As a
prerequisite to such consent, the proposed transferee must provide the Tax
Matters Person, the Seller and the Trustee with an affidavit that the proposed
transferee is a Permitted Transferee (and, unless the Tax Matters Person and the
Seller consent to the transfer to a person who is not a U.S. Person, an
affidavit that it is a U.S. Person) as provided in Subsection 5.05(b).

         (b) No transfer, sale or other disposition of a Residual Certificate
(including a beneficial interest therein) may be made unless, prior to the
transfer, sale or other disposition of a Residual Certificate, the proposed
transferee (including the initial purchasers thereof) delivers to the Tax
Matters Person, the Trustee and the Seller an affidavit in the form attached
hereto as Exhibit E stating, among other things, that as of the date of such
transfer (i) such transferee is a Permitted Transferee and that (ii) such
transferee is not acquiring such Residual Certificate for the account of any
person who is not a Permitted Transferee. The Tax Matters Person shall not
consent to a transfer of a Residual Certificate if it has actual knowledge that
any statement made in the affidavit issued pursuant to the preceding sentence is
not true. Notwithstanding any transfer, sale or other disposition of a Residual
Certificate to any Person who is not a Permitted Transferee, such transfer, sale
or other disposition shall be deemed to be of no legal force or effect
whatsoever and such Person shall not be deemed to be a Holder of a Residual
Certificate for any purpose hereunder, including, but not limited to, the
receipt of distributions thereon. If any purported transfer shall be in
violation of the provisions of this Subsection 5.05(b), then the prior Holder
thereof shall, upon discovery that the transfer of such Residual Certificate was
not in fact permitted by this Subsection 5.05(b), be restored to all rights as a
Holder thereof retroactive to the date of the purported transfer. None of the
Trustee, the Tax Matters Person or the Seller shall be under any liability to
any Person for any registration or transfer of a Residual Certificate that is
not permitted by this Subsection 5.05(b) or for making payments due on such
Residual Certificate to the purported Holder thereof or taking any other action
with respect to such purported Holder under the provisions of this Agreement so
long as the written affidavit referred to above was received with respect to
such transfer, and the Tax Matters Person, the Trustee and the Seller, as
applicable, had no knowledge that it was untrue. The prior Holder shall be
entitled to recover from any purported Holder of a Residual Certificate that was
in fact not a permitted transferee under this Subsection 5.05(b) at the time it
became a Holder all payments made on such Residual Certificate. Each Holder of a
Residual Certificate, by acceptance thereof, shall be deemed for all purposes to
have consented to the provisions of this Subsection 5.05(b) and to any amendment
of this Agreement deemed necessary (whether as a result of new legislation or
otherwise) by counsel of the Tax Matters Person or the Seller to ensure that the
Residual Certificates are not transferred to any Person who is not a Permitted
Transferee and that any transfer of such Residual Certificates will not cause
the imposition of a tax upon the Trust or cause any REMIC to fail to qualify as
a REMIC.

         (c) Unless the Tax Matters Person shall have consented in writing
(which consent may be withheld in the Tax Matters Person's sole discretion), the
Residual Certificates (including a beneficial interest therein) may not be
purchased by or transferred to any person who is not a United States Person.

                                      -59-

<PAGE>

         (d) By accepting a Residual Certificate, the purchaser thereof agrees
to be a Tax Matters Person, and appoints the Securities Administrator to act as
its agent with respect to all matters concerning the tax obligations of the
Trust.

         Section 5.06 RESTRICTIONS ON TRANSFERABILITY OF CERTIFICATES. (a) No
offer, sale, transfer or other disposition (including pledge) of any Certificate
shall be made by any Holder thereof unless registered under the Securities Act,
or an exemption from the registration requirements of the Securities Act and any
applicable state securities or "Blue Sky" laws is available and the prospective
transferee (other than the Seller) of such Certificate signs and delivers to the
Trustee an Investment Letter, if the transferee is an Institutional Accredited
Investor, in the form set forth as Exhibit F-l hereto, or a Rule 144A
Certificate, if the transferee is a QIB, in the form set forth as Exhibit F-2
hereto. Notwithstanding the provisions of the immediately preceding sentence, no
restrictions shall apply with respect to the transfer or registration of
transfer of a beneficial interest in any Certificate that is a Global
Certificate of a Class to a transferee that takes delivery in the form of a
beneficial interest in the Global Certificate of such Class provided that each
such transferee shall be deemed to have made such representations and warranties
contained in the Rule 144A Certificate as are sufficient to establish that it is
a QIB. In the case of a proposed transfer of any Certificate to a transferee
other than a QIB, the Trustee may require an Opinion of Counsel that such
transaction is exempt from the registration requirements of the Securities Act.
The cost of such opinion shall not be an expense of the Trustee or the Trust
Fund.

         (b) The Private Certificates shall each bear a Securities Legend.

         Section 5.07 ERISA RESTRICTIONS. (a) Subject to the provisions of
subsection (b), no Residual Certificates or Private Certificates may be acquired
directly or indirectly by, or on behalf of, an employee benefit plan or other
retirement arrangement which is subject to Title I of ERISA and/or Section 4975
of the Code, unless the proposed transferee provides either (i) the Trustee and
the Securities Administrator with an Opinion of Counsel satisfactory to the
Trustee, the Master Servicer and the Securities Administrator, which opinion
will not be at the expense of the Trustee, the Master Servicer or the Securities
Administrator, that the purchase of such Certificates by or on behalf of such
Plan is permissible under applicable law, will not constitute or result in a
nonexempt prohibited transaction under ERISA or Section 4975 of the Code and
will not subject the Trustee, the Master Servicer or the Securities
Administrator to any obligation in addition to those undertaken in the Agreement
or (ii) in the case of the Class B-4, Class B-5 and Class B-6 Certificates, a
representation or certification to the Trustee (upon which the Trustee is
authorized to rely) to the effect that the proposed transfer and/or holding of
such a Certificate and the servicing, management and operation of the Trust: (I)
will not result in a prohibited transaction under Section 406 of ERISA or
Section 4975 of the Code which is not covered under an individual or class
prohibited transaction exemption including but not limited to Department of
Labor Prohibited Transaction Exemption ("PTE") 84-14 (Class Exemption for Plan
Asset Transactions Determined by Independent Qualified Professional Asset
Managers); PTE 91-38 (Class Exemption for Certain Transactions Involving Bank
Collective Investment Funds); PTE 90-1 (Class Exemption for Certain Transactions
Involving Insurance Company Pooled Separate Accounts), PTE 95-60 (Class
Exemption for Certain Transactions Involving Insurance Company General
Accounts), and PTCE 96-23 (Class Exemption for Plan Asset Transactions
Determined by In-House Asset Managers and (II) will not subject the

                                      -60-

<PAGE>

Seller, the Securities Administrator, the Master Servicer or the Trustee to any
obligation in addition to those undertaken in the Agreement.

         (b) Any Person acquiring an interest in a Global Certificate which is a
Private Certificate, by acquisition of such Certificate, shall be deemed to have
represented to the Trustee that in the case of the Class B-4, Class B-5 and
Class B-6 Certificates, either: (i) it is not acquiring an interest in such
Certificate directly or indirectly by, or on behalf of, an employee benefit plan
or other retirement arrangement which is subject to Title I of ERISA and/or
Section 4975 of the Code, or (ii) the transfer and/or holding of an interest in
such Certificate to that Person and the subsequent servicing, management and/or
operation of the Trust and its assets: (I) will not result in any prohibited
transaction which is not covered under an individual or class prohibited
transaction exemption, including, but not limited to, PTE 84-14, PTE 91-38, PTE
90-1, PTE 95-60 or PTE 96-23 and (II) will not subject the Seller, the Master
Servicer, the Securities Administrator or the Trustee to any obligation in
addition to those undertaken in the Agreement.

         (c) None of the Trustee, the Master Servicer, or the Securities
Administrator will be required to monitor, determine or inquire as to compliance
with the transfer restrictions with respect to the Global Certificates. Any
attempted or purported transfer of any Certificate in violation of the
provisions of Subsections (a) or (b) above shall be void ab initio and such
Certificate shall be considered to have been held continuously by the prior
permitted Certificateholder. Any transferor of any Certificate in violation of
such provisions, shall indemnify and hold harmless the Trustee, the Master
Servicer and the Securities Administrator from and against any and all
liabilities, claims, costs or expenses incurred by the Trustee, the Master
Servicer or the Securities Administrator as a result of such attempted or
purported transfer. The Trustee shall have no liability for transfer of any such
Global Certificates in or through book-entry facilities of any Depository or
between or among Depository Participants or Certificate Owners made in violation
of the transfer restrictions set forth herein.

         Section 5.08 RULE 144A INFORMATION. For so long as any Certificates are
outstanding and are "restricted securities" within the meaning of Rule 144(a)(3)
of the Securities Act, (1) the Seller will provide or cause to be provided to
any holder of such Certificates and any prospective purchaser thereof designated
by such a holder, upon the request of such holder or prospective purchaser, the
information required to be provided to such holder or prospective purchaser by
Rule 144A(d)(4) under the Securities Act; and (2) the Seller shall update such
information from time to time in order to prevent such information from becoming
false and misleading and will take such other actions as are necessary to ensure
that the safe harbor exemption from the registration requirements of the
Securities Act under Rule 144A is and will be available for resales of such
Certificates conducted in accordance with Rule 144A.

                           Accrued Certificate Interest thereon remaining
                           undistributed from previous Distribution Dates, to
                           the extent of remaining Group 2 Available Funds; and

                           (iii) third, sequentially, in the following order, to
                           the Class R-I, Class R-II and Class II-A
                           Certificates, in reduction of the Current Principal
                           Amounts thereof, the Group 2 Senior Optimal Principal
                           Amount for such Distribution Date to the extent of
                           remaining Group 2 Available Funds, until the Current
                           Principal Amounts thereof have been reduced to zero;

         (b) On the first Distribution Date, the Class I-X Certificates will be
entitled to receive a distribution equal to the interest accrued on the Current
Principal Amounts of the Class I-A-1, Class I-A-2-1 and Class I-A-2-2
Certificates at the Pass-Through Rate of the those certificates from the Closing
Date to the last day of the month of such distribution;

                  (A) Except as provided in (D) and (E) below, on each
                  Distribution Date prior to the Cross-Over Date, an amount
                  equal to any remaining Group 1 and Group 2 Available Funds
                  after the distributions in (A) and (B) above will be
                  distributed sequentially, in the following order, to the Class
                  B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6

                  following order: (a) the Accrued Certificate Interest thereon
                  for such Distribution Date, (b) any Accrued Certificate
                  Interest thereon remaining undistributed from previous
                  Distribution Dates and (c) such Class's Allocable Share for
                  such Distribution Date, in each case, to the extent of
                  remaining Available Funds.

                  (B) On each Distribution Date prior to the Cross-Over Date,
                  but after the reduction of the Current Principal Amount of the
                  Group 1 or Group 2 Senior Certificates to zero, the remaining
                  Class or Classes of Senior Certificates will be entitled to
                  receive in reduction of their Current Principal Amounts, pro
                  rata based upon their Current Principal Amounts immediately
                  prior to such Distribution Date, in addition to any Principal
                  Prepayments related to such remaining Senior Certificates'
                  respective Loan Group allocated to such Group of Senior
                  Certificates,

                  100% of the Principal Prepayments on any Mortgage Loan in the
                  Loan Group relating to the fully repaid Class of Senior
                  Certificates; provided, however, that if (A) the weighted
                  average Subordinate Percentage equals or exceeds 11.50% on
                  such Distribution Date and (B) the aggregate Scheduled
                  Principal Balance of the Mortgage Loans delinquent 60 days or
                  more (including for this purpose any such Mortgage Loans in
                  foreclosure and Mortgage Loans with respect to which the
                  related Mortgaged Property has been acquired by the Trust),
                  averaged over the last six months, as a percentage of the sum
                  of the aggregate Current Principal Amount of the Subordinate
                  Certificates does not exceed 100%, then the additional
                  allocation of Principal Prepayments to the Senior Certificates
                  in accordance with this clause (D) will not be made.

                  (C) If on any Distribution Date on which the aggregate Current
                  Principal Amount of any Class or Classes of Senior
                  Certificates would be greater than the aggregate Scheduled
                  Principal Balance of the Mortgage Loans in its related Loan
                  Group and any Subordinate Certificates are still outstanding
                  in each case after giving effect to distributions to be made
                  on such Distribution Date, (i) 100% of amounts otherwise
                  allocable to the Subordinate Certificates in respect of
                  principal will be distributed to such Class or Classes of
                  Senior Certificates in reduction of the Current Principal
                  Amounts thereof, until the aggregate Current Principal Amount
                  of such Class or Classes of Senior Certificates is an amount
                  equal to the aggregate Scheduled Principal Balance of the
                  Mortgage Loans in its related Loan Group, and (ii) the Accrued
                  Certificate Interest otherwise allocable to the Subordinate
                  Certificates on such Distribution Date will be reduced, if
                  necessary, and distributed to such Class or Classes of Senior
                  Certificates in an amount equal to the Accrued Certificate
                  Interest for such Distribution Date on the excess of (x) the
                  aggregate Current Principal Balance of such Class or Classes
                  of Senior Certificates over (y) the aggregate Scheduled
                  Principal Balance of the Mortgage Loans in the related Loan
                  Group. Any such reduction in the Accrued Certificate Interest
                  on the Subordinate Certificates will be allocated in reverse
                  order of the Subordinate Certificates numerical designations,
                  commencing with the Class B-6 Certificates.

         (c) If, after distributions have been made pursuant to priorities first
and second of clauses (a)(i)(A) and (B) above on any Distribution Date, the
remaining Group 1 or Group 2 Available Funds are less than the sum of the Group
1 or Group 2 Senior Optimal Principal Amounts such amount shall be reduced, and
such remaining funds will be distributed on the related Senior Certificates on
the basis of such reduced amount.

         (d) "Pro rata" distributions among Classes of Certificates will be made
in proportion to the then Current Principal Amount of such Classes.

         (e) On each Distribution Date, any Available Funds remaining after
payment of interest and principal to the Classes of Certificates entitled
thereto, as described above, will be distributed to the Class R-II Certificates;
provided that if on any Distribution Date there are any Group 1 or Group 2
Available Funds remaining after payment of interest and principal to a Class or
Classes of Certificates entitled thereto, such amounts will be distributed to
the other Classes of Senior

                                      -64-

<PAGE>

Certificates, pro rata, based upon their Current Principal Amounts, until all
amounts due to all Classes of Senior Certificates have been paid in full, before
any amounts are distributed to the Class R-II Certificates.

         (f) No Accrued Certificate Interest will be payable with respect to any
Class of Certificates or Component of the Class I-X Certificates after the
Distribution Date on which the Current Principal Amount or Notional Amount, as
applicable, of such Certificate or Component has been reduced to zero.

         (g) If on any Distribution Date the Available Funds for the Senior
Certificates in any Certificate Group is less than the Accrued Certificate
Interest on the related Senior Certificates for such Distribution Date prior to
reduction for Net Interest Shortfall and the interest portion of Realized
Losses, the shortfall will be allocated among the holders of each Class of
Senior Certificates in such Certificate Group in proportion to the respective
amounts of Accrued Certificate Interest that would have been allocated thereto
in the absence of such Net Interest Shortfall and/or Realized Losses for such
Distribution Date. In addition, the amount of any interest shortfalls will
constitute unpaid Accrued Certificate Interest and will be distributable to
holders of the Certificates of the related Classes entitled to such amounts on
subsequent Distribution Dates, to the extent of the applicable Available Funds
after current interest distributions as required herein. Any such amounts so
carried forward will not bear interest. Shortfalls in interest payments will not
be offset by a reduction in the servicing compensation of the Servicer, the
Master Servicer or otherwise, except to the extent of applicable Compensating
Interest Payments.

         (h) The expenses and fees of the Trust shall be paid by each of the
REMICs, to the extent that such expenses relate to the assets of each of such
respective REMICs, and all other expenses and fees of the Trust shall be paid
pro rata by each of the REMICs.

         Section 6.02 ALLOCATION OF LOSSES. (a) On or prior to each
Determination Date, the Master Servicer shall determine the amount of any
Realized Loss in respect of each Mortgage Loan that occurred during the
immediately preceding calendar month.

         (b) With respect to any Certificates on any Distribution Date, the
principal portion of each Realized Loss on a Mortgage Loan shall be allocated as
follows:

                  first, to the Class B-6 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                  second, to the Class B-5 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                  third, to the Class B-4 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                  fourth, to the Class B-3 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                                      -65-

<PAGE>

                  fifth, to the Class B-2 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                  sixth, to the Class B-1 Certificates until the Current
         Principal Amount thereof has been reduced to zero;

                  seventh, if such loss is on a Group 1 or Group 2 Mortgage
         Loan, to the Group 1 or Group 2 Senior Certificates, respectively.

                  eighth, to the Senior Certificates (other than the Interest
         Only Certificates), on a pro rata basis.

         (c) Notwithstanding the foregoing clause (b), no such allocation of any
Realized Loss shall be made on a Distribution Date to any Class of Certificates
to the extent that such allocation would result in the reduction of the
aggregate Current Principal Amounts of all the Certificates as of such
Distribution Date, after giving effect to all distributions and prior
allocations of Realized Losses on such date, to an amount less than the
aggregate Scheduled Principal Balance of all of the Mortgage Loans as of the
first day of the month of such Distribution Date (such limitation, the "Loss
Allocation Limitation").

         (d) Any Realized Losses allocated to a Class of Certificates shall be
allocated among the Certificates of such Class in proportion to their respective
Current Principal Amounts. Any allocation of Realized Losses shall be
accomplished by reducing the Current Principal Amount of the related
Certificates on the related Distribution Date.

         (e) Realized Losses shall be allocated on the Distribution Date in the
month following the month in which such loss was incurred and, in the case of
the principal portion thereof, after giving effect to distributions made on such
Distribution Date.

         (f) On each Distribution Date, the Securities Administrator shall
determine and notify the Trustee of the Subordinate Certificate Writedown
Amount. Any such Subordinate Certificate Writedown Amount shall effect a
corresponding reduction in the Current Principal Amount of (i) if prior to the
Cross-Over Date, the Current Principal Amounts of the Subordinate Certificates,
in the reverse order of their numerical Class designations and (ii) from and
after the Cross-Over Date, the Senior Certificates which reduction shall occur
on such Distribution Date after giving effect to distributions made on such
Distribution Date.

         (g) Any Net Interest Shortfall will be allocated among the Classes of
Certificates in proportion to the respective amounts of Accrued Certificate
Interest that would have been allocated thereto in the absence of such Net
Interest Shortfall for such Distribution Date. The interest portion of any
Realized Losses with respect to the Mortgage Loans occurring on or prior to the
Cross-Over Date will not be allocated among any Certificates, but will reduce
the amount of Available Funds on the related Distribution Date. As a result of
the subordination of the Subordinate Certificates in right of distribution, such
Realized Losses will be borne by the Subordinate Certificates in inverse order
of their numerical Class designations. Following the Cross-Over Date, the
interest portion of

                                      -66-

<PAGE>

Realized Losses on the Mortgage Loans in any Loan Group will be allocated to the
related Senior Certificates.

         Section 6.03 PAYMENTS. (a) On each Distribution Date, other than the
final Distribution Date, the Trustee shall distribute to each Certificateholder
of record on the directly preceding Record Date the Certificateholder's pro rata
share of its Class (based on the aggregate Fractional Undivided Interest
represented by such Holder's Certificates) of all amounts required to be
distributed on such Distribution Date to such Class, based on information
provided to the Securities Administrator by the Master Servicer or the Trustee,
as applicable. The Securities Administrator shall calculate the amount to be
distributed to each Class and, based on such amounts, the Securities
Administrator shall determine the amount to be distributed to each
Certificateholder. All of the Securities Administrator's calculations of
payments shall be based solely on information provided to the Securities
Administrator by the Servicer or the Trustee, as applicable. The Securities
Administrator shall not be required to confirm, verify or recompute any such
information but shall be entitled to rely conclusively on such information.

         (b) Payment of the above amounts to each Certificateholder shall be
made (i) by check mailed to each Certificateholder entitled thereto at the
address appearing in the Certificate Register or (ii) upon receipt by the
Trustee on or before the fifth Business Day preceding the Record Date of written
instructions from a Certificateholder by wire transfer to a United States dollar
account maintained by the payee at any United States depository institution with
appropriate facilities for receiving such a wire transfer; provided, however,
that the final payment in respect of each Class of Certificates will be made
only upon presentation and surrender of such respective Certificates at the
office or agency of the Trustee specified in the notice to Certificateholders of
such final payment.

         Section 6.05 MONTHLY ADVANCES. If the Scheduled Payment on a Mortgage
Loan that was due on a related Due Date and is delinquent other than as a result
of application of the Relief Act and for which the Servicer was required to make
an advance pursuant to the related Servicing Agreement exceeds the amount
deposited in the Distribution Account which will be used for an advance with
respect to such Mortgage Loan, the Master Servicer will remit to the Trustee for
deposit in the Distribution Account not later than the Business Day immediately
preceding the related Distribution Date an amount equal to such deficiency, net
of the Servicing Fee and Master Servicing Fee for such Mortgage Loan, except to
the extent the Master Servicer determines any such advance to be nonrecoverable
from Liquidation Proceeds, Insurance Proceeds or future payments on the Mortgage
Loan for which such Monthly Advance was made. Subject to the foregoing, the
Master Servicer shall continue to make such advances through the date that the
Servicer is required to do so under the ServicingAgreement. If applicable, on
the Distribution Account Deposit Date, the Master Servicer shall present an
Officer's Certificate to the Trustee (i) stating that the Master Servicer elects
not to make a Monthly Advance in a stated amount and (ii) detailing the reason
it deems the advance to be nonrecoverable.

shall be necessary to protect the validity and enforceability of this Agreement,
the Certificates or any of the Mortgage Loans and to perform its duties under
this Agreement.

         Any Person into which the Master Servicer may be merged or
consolidated, or any corporation resulting from any merger or consolidation to
which the Master Servicer shall be a party, or any Person succeeding to the
business of the Master Servicer, shall be the successor of the Master Servicer
hereunder, without the execution or filing of any paper or further act on the
part of any of the parties hereto, anything herein to the contrary
notwithstanding.

         Section 7.03 INDEMNIFICATION OF THE TRUSTEE, THE MASTER SERVICER AND
THE SECURITIES ADMINISTRATOR. (a) The Master Servicer agrees to indemnify the
Indemnified Persons for, and to hold them harmless against, any loss, liability
or expense (including reasonable legal fees and disbursements of counsel)
incurred on their part that may be sustained in connection with, arising out of,
or relating to, any claim or legal action (including any pending or threatened
claim or legal action) relating to this Agreement or the Certificates (i)
related to the Master Servicer's failure to perform its duties in compliance
with this Agreement (except as any such loss, liability or expense shall be
otherwise reimbursable pursuant to this Agreement) or (ii) incurred by reason of
the Master Servicer's willful misfeasance, bad faith or gross negligence in the
performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder, provided, in each case, that with respect to
any such claim or legal action (or pending or threatened claim or legal action),
the Trustee shall have given the Master Servicer and the Seller written notice
thereof promptly after the Trustee shall have with respect to such claim or
legal action knowledge thereof. This indemnity shall survive the resignation or
removal of the Trustee, Master Servicer or the Securities Administrator and the
termination of this Agreement.

         (b) The Seller will indemnify any Indemnified Person for any loss,
liability or expense of any Indemnified Person not otherwise referred to in
Subsection (a) above.

         Section 7.04 LIMITATIONS ON LIABILITY OF THE MASTER SERVICER AND
OTHERS. Subject to the obligation of the Master Servicer to indemnify the
Indemnified Persons pursuant to Section 7.03:

         (a) Neither the Master Servicer nor any of the directors, officers,
employees or agents of the Master Servicer shall be under any liability to the
Indemnified Persons, the Seller, the Trust Fund or the Certificateholders for
taking any action or for refraining from taking any action in good faith
pursuant to this Agreement, or for errors in judgment; provided, however, that
this provision shall not protect the Master Servicer or any such Person against
any breach of warranties or representations made herein or any liability which
would otherwise be imposed by reason of such Person's willful misfeasance, bad
faith or gross negligence in the performance of duties or by reason of reckless
disregard of obligations and duties hereunder.

         (b) The Master Servicer and any director, officer, employee or agent of
the Master Servicer may rely in good faith on any document of any kind prima
facie properly executed and submitted by any Person respecting any matters
arising hereunder.

         (c) The Master Servicer, the Custodian and any director, officer,
employee or agent of the Master Servicer or the Custodian shall be indemnified
by the Trust and held harmless thereby against any loss, liability or expense
(including reasonable legal fees and disbursements of counsel) incurred on their
part that may be sustained in connection with, arising out of, or related to,
any claim or legal action (including any pending or threatened claim or legal
action) relating to this Agreement, the Certificates or any Servicing Agreement
(except to the extent that the Master Servicer is indemnified by the Servicer
thereunder), other than (i) any such loss, liability or expense related to the
Master Servicer's failure to perform its duties in compliance with this
Agreement (except as any such loss, liability or expense shall be otherwise
reimbursable pursuant to this Agreement), or to the Custodian's failure to
perform its duties under the Custodial Agreement, respectively, or (ii) any such
loss, liability or expense incurred by reason of the Master Servicer's or the
Custodian's willful misfeasance, bad faith or gross negligence in the
performance of duties hereunder or under the Custodial Agreement, as applicable,
or by reason of reckless disregard of obligations and duties hereunder or under
the Custodial Agreement, as applicable.

         (d) The Master Servicer shall not be under any obligation to appear in,
prosecute or defend any legal action that is not incidental to its duties under
this Agreement and that in its opinion may involve it in any expense or
liability; provided, however, the Master Servicer may in its discretion, with
the consent of the Trustee (which consent shall not be unreasonably withheld),
undertake any such action which it may deem necessary or desirable with respect
to this Agreement and the rights and duties of the parties hereto and the
interests of the Certificateholders hereunder. In such event, the legal expenses
and costs of such action and any liability resulting therefrom shall be
expenses, costs and liabilities of the Trust Fund, and the Master Servicer shall
be entitled to be reimbursed therefor out of the Distribution Account as
provided by Section 4.03. Nothing in this Subsection 7.04(d) shall affect the
Master Servicer's obligation to supervise, or to take such actions as are
necessary to ensure, the servicing and administration of the Mortgage Loans
pursuant to Subsection 3.01(a).

         (e) In taking or recommending any course of action pursuant to this
Agreement, unless specifically required to do so pursuant to this Agreement, the
Master Servicer shall not be required

                                      -72-

<PAGE>

to investigate or make recommendations concerning potential liabilities which
the Trust might incur as a result of such course of action by reason of the
condition of the Mortgaged Properties but shall give notice to the Trustee if it
has notice of such potential liabilities.

         (f) The Master Servicer shall not be liable for any acts or omissions
of any Servicer, except as otherwise expressly provided herein.

         Section 7.05 MASTER SERVICER NOT TO RESIGN. Except as provided in
Section 7.07, the Master Servicer shall not resign from the obligations and
duties hereby imposed on it except upon a determination that any such duties
hereunder are no longer permissible under applicable law and such
impermissibility cannot be cured. Any such determination permitting the
resignation of the Master Servicer shall be evidenced by an Opinion of
Independent Counsel to such effect delivered to the Trustee. No such resignation
by the Master Servicer shall become effective until EMC or the Trustee or a
successor to the Master Servicer reasonably satisfactory to the Trustee shall
have assumed the responsibilities and obligations of the Master Servicer in
accordance with Section 8.02 hereof. The Trustee shall notify the Rating
Agencies of the resignation of the Master Servicer.

         Section 7.06 SUCCESSOR MASTER SERVICER. In connection with the
appointment of any successor Master Servicer or the assumption of the duties of
the Master Servicer, EMC or the Trustee may make such arrangements for the
compensation of such successor master servicer out of payments on the Mortgage
Loans as EMC or the Trustee and such successor master servicer shall agree. If
the successor master servicer does not agree that such market value is a fair
price, such successor master servicer shall obtain two quotations of market
value from third parties actively engaged in the servicing of single-family
mortgage loans.

         Section 7.07 SALE AND ASSIGNMENT OF MASTER SERVICING. The Master
Servicer may sell and assign its rights and delegate its duties and obligations
in its entirety as Master Servicer under this Agreement and EMC may terminate
the Master Servicer without cause and select a new Master Servicer; provided,
however, that: (i) the purchaser or transferee accepting such assignment and
delegation (a) shall be a Person which shall be qualified to service mortgage
loans for Fannie Mae or Freddie Mac; (b) shall have a net worth of not less than
$10,000,000 (unless otherwise approved by each Rating Agency pursuant to clause
(ii) below); (c) shall be reasonably satisfactory to the Trustee (as evidenced
in a writing signed by the Trustee); and (d) shall execute and deliver to the
Trustee an agreement, in form and substance reasonably satisfactory to the
Trustee, which contains an assumption by such Person of the due and punctual
performance and observance of each covenant and condition to be performed or
observed by it as master servicer under this Agreement, any custodial agreement
from and after the effective date of such agreement; (ii) each Rating Agency
shall be given prior written notice of the identity of the proposed successor to
the Master Servicer and each Rating Agency's rating of the Certificates in
effect immediately prior to such assignment, sale and delegation will not be
downgraded, qualified or withdrawn as a result of such assignment, sale and
delegation, as evidenced by a letter to such effect delivered to the Master
Servicer and the Trustee; (iii) the Master Servicer assigning and selling the
master servicing shall deliver to the Trustee an Officer's Certificate and an
Opinion of Independent Counsel, each stating that all conditions precedent to
such action under this Agreement have been completed and such action is
permitted by and complies with the terms of this Agreement; and (iv) in the
event the Master Servicer is terminated without cause by EMC, EMC shall pay the
terminated Master Servicer a

                                      -73-

<PAGE>

termination fee equal to 0.25% of the aggregate Scheduled Principal Balance of
the Mortgage Loans at the time the master servicing of the Mortgage Loans is
transferred to the successor Master Servicer. No such assignment or delegation
shall affect any liability of the Master Servicer arising prior to the effective
date thereof.

                                     Default

         Section 8.01 EVENTS OF DEFAULT. "Event of Default," wherever used
herein, means any one of the following events (whatever the reason for such
Event of Default and whether it shall be voluntary or involuntary or be effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body) and
only with respect to the defaulting Master Servicer:

                  (i) The Master Servicer fails to remit to the Trustee for
         deposit in the Distribution Account any amount so required to be
         deposited by the Master Servicer pursuant to this Agreement, and such
         failure continues unremedied for a period of three Business Days after
         the date upon which written notice of such failure, requiring the same
         to be remedied, shall have been given to the Master Servicer; or

                  (ii) The Master Servicer fails to observe or perform in any
         material respect any other material covenants and agreements set forth
         in this Agreement to be performed by it, which covenants and agreements
         materially affect the rights of Certificateholders, and such failure
         continues unremedied for a period of 60 days after the date on which
         written notice of such failure, properly requiring the same to be
         remedied, shall have been given to the Master Servicer by the Trustee
         or to the Master Servicer and the Trustee by the Holders of
         Certificates evidencing Fractional Undivided Interests aggregating not
         less than 25% of the Trust Fund; or

                  (iii) There is entered against the Master Servicer a decree or
         order by a court or agency or supervisory authority having jurisdiction
         in the premises for the appointment of a conservator, receiver or
         liquidator in any insolvency, readjustment of debt, marshaling of
         assets and liabilities or similar proceedings, or for the winding up or
         liquidation of its affairs, and the continuance of any such decree or
         order is unstayed and in effect for a period of 60 consecutive days, or
         an involuntary case is commenced against the Master Servicer under any
         applicable insolvency or reorganization statute and the petition is not
         dismissed within 60 days after the commencement of the case; or

                  (iv) The Master Servicer consents to the appointment of a
         conservator or receiver or liquidator in any insolvency, readjustment
         of debt, marshaling of assets and liabilities or similar proceedings of
         or relating to the Master Servicer or substantially all of its
         property; or the Master Servicer admits in writing its inability to pay
         its debts generally as they become due, files a petition to take
         advantage of any applicable insolvency or reorganization statute, makes
         an assignment for the benefit of its creditors, or voluntarily suspends
         payment of its obligations; or

                  (v) The Master Servicer assigns or delegates its duties or
         rights under this Agreement in contravention of the provisions
         permitting such assignment or delegation under Sections 7.05 or 7.07.

                                      -75-

<PAGE>

In each and every such case, so long as such Event of Default with respect to
the Master Servicer shall not have been remedied, either the Trustee or the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% of the principal of the Trust Fund, by notice in writing to
the Master Servicer (and to the Trustee if given by such Certificateholders),
with a copy to the Rating Agencies, and with the consent of EMC, may terminate
all of the rights and obligations (but not the liabilities) of the Master
Servicer under this Agreement and in and to the Mortgage Loans and/or the REO
Property serviced by the Master Servicer and the proceeds thereof. Upon the
receipt by the Master Servicer of the written notice, all authority and power of
the Master Servicer under this Agreement, whether with respect to the
Certificates, the Mortgage Loans, REO Property or under any other related
agreements (but only to the extent that such other agreements relate to the
Mortgage Loans or related REO Property) shall, subject to Section 8.02,
automatically and without further action pass to and be vested in the Trustee
pursuant to this Section 8.01; and, without limitation, the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of the Master
Servicer as attorney-in-fact or otherwise, any and all documents and other
instruments and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. The Master Servicer agrees to cooperate with
the Trustee in effecting the termination of the Master Servicer's rights and
obligations hereunder, including, without limitation, the transfer to the
Trustee of (i) the property and amounts which are then or should be part of the
Trust or which thereafter become part of the Trust; and (ii) originals or copies
of all documents of the Master Servicer reasonably requested by the Trustee to
enable it to assume the Master Servicer's duties thereunder. In addition to any
other amounts which are then, or, notwithstanding the termination of its
activities under this Agreement, may become payable to the Master Servicer under
this Agreement, the Master Servicer shall be entitled to receive, out of any
amount received on account of a Mortgage Loan or related REO Property, that
portion of such payments which it would have received as reimbursement under
this Agreement if notice of termination had not been given. The termination of
the rights and obligations of the Master Servicer shall not affect any
obligations incurred by the Master Servicer prior to such termination.

         Section 8.02 TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR. (a) Upon the
receipt by the Master Servicer of a notice of termination pursuant to Section
8.01 or an Opinion of Independent Counsel pursuant to Section 7.05 to the effect
that the Master Servicer is legally unable to act or to delegate its duties to a
Person which is legally able to act, the Trustee shall automatically become the
successor in all respects to the Master Servicer in its capacity under this
Agreement and the transactions set forth or provided for herein and shall
thereafter be subject to all the responsibilities, duties, liabilities and
limitations on liabilities relating thereto placed on the Master Servicer by the
terms and provisions hereof; provided, however, that EMC shall have the right to
either (a) immediately assume the duties of the Master Servicer or (b) select a
successor Master Servicer; provided further, however, that the Trustee shall
have no obligation whatsoever with respect to any liability (other than advances
deemed recoverable and not previously made) incurred by the Master Servicer at
or prior to the time of termination. As compensation therefor, but subject to
Section 7.06, the Trustee shall be entitled to all funds relating to the
Mortgage Loans which the Master Servicer would have been entitled to retain if
the Master Servicer had continued to act hereunder, except for those amounts due
the Master Servicer as reimbursement permitted under this Agreement for advances
previously made or expenses previously incurred. Notwithstanding the above, the
Trustee may, if it shall be unwilling so to act, or shall, if it is legally
unable so to act, appoint or petition a

                                      -76-

<PAGE>

court of competent jurisdiction to appoint, any established housing and home
finance institution which is a Fannie Mae- or Freddie Mac-approved servicer, and
with respect to a successor to the Master Servicer only, having a net worth of
not less than $10,000,000, as the successor to the Master Servicer hereunder in
the assumption of all or any part of the responsibilities, duties or liabilities
of the Master Servicer hereunder; provided, that the Trustee shall obtain a
letter from each Rating Agency that the ratings, if any, on each of the
Certificates will not be lowered as a result of the selection of the successor
to the Master Servicer. Pending appointment of a successor to the Master
Servicer hereunder, the Trustee shall act in such capacity as hereinabove
provided. In connection with such appointment and assumption, the Trustee may
make such arrangements for the compensation of such successor out of payments on
the Mortgage Loans as it and such successor shall agree; provided, however, that
the provisions of Section 7.06 shall apply, no such compensation shall be in
excess of that permitted the Trustee under this Subsection 8.02(a), and that
such successor shall undertake and assume the obligations of the Trustee to pay
compensation to any third Person acting as an agent or independent contractor in
the performance of master servicing responsibilities hereunder. The Trustee and
such successor shall take such action, consistent with this Agreement, as shall
be necessary to effectuate any such succession.

         (b) If the Trustee shall succeed to any duties of the Master Servicer
respecting the Mortgage Loans as provided herein, it shall do so in a separate
capacity and not in its capacity as Trustee and, accordingly, the provisions of
Article IX shall be inapplicable to the Trustee in its duties as the successor
to the Master Servicer in the servicing of the Mortgage Loans (although such
provisions shall continue to apply to the Trustee in its capacity as Trustee);
the provisions of Article VII, however, shall apply to it in its capacity as
successor master servicer.

         Section 8.03 NOTIFICATION TO CERTIFICATEHOLDERS. Upon any termination
or appointment of a successor to the Master Servicer, the Trustee shall give
prompt written notice thereof to Certificateholders at their respective
addresses appearing in the Certificate Register and to the Rating Agencies.

         Section 8.04 WAIVER OF DEFAULTS. The Trustee shall transmit by mail to
all Certificateholders, within 60 days after the occurrence of any Event of
Default known to the Trustee, unless such Event of Default shall have been
cured, notice of each such Event of Default hereunder known to the Trustee. The
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% of the Trust Fund may, on behalf of all Certificateholders,
waive any default by the Master Servicer in the performance of its obligations
hereunder and the consequences thereof, except a default in the making of or the
causing to be made any required distribution on the Certificates. Upon any such
waiver of a past default, such default shall be deemed to cease to exist, and
any Event of Default arising therefrom shall be deemed to have been timely
remedied for every purpose of this Agreement. No such waiver shall extend to any
subsequent or other default or impair any right consequent thereon except to the
extent expressly so waived. The Trustee shall give notice of any such waiver to
the Rating Agencies.

         Section 8.05 LIST OF CERTIFICATEHOLDERS. Upon written request of three
or more Certificateholders of record, for purposes of communicating with other
Certificateholders with respect to their rights under this Agreement, the
Trustee will afford such Certificateholders access during business hours to the
most recent list of Certificateholders held by the Trustee.

         Section 9.01 INDEMNIFICATION OF THE TRUSTEE AND THE SECURITIES
ADMINISTRATOR. (a) The Trust shall indemnify the Indemnified Persons for, and
will hold them harmless against, any loss, liability or expense incurred on
their part, arising out of, or in connection with, this Agreement and the
Certificates, including the costs and expenses (including reasonable legal fees
and expenses) of defending themselves against any such claim other than (i) any
loss, liability or expense related to such Indemnified Person's failure to
perform such Indemnified Person's duties in strict compliance with this
Agreement (except as any such loss, liability or expense shall be otherwise
reimbursable pursuant to this Agreement) and (ii) any loss, liability or expense
incurred by reason of such Indemnified Person's willful misfeasance, bad faith
or negligence in the performance of duties hereunder or by reason of reckless
disregard of obligations and duties hereunder. This indemnity shall survive the
resignation or removal of the Trustee and the termination of this Agreement.

         (b) The Seller will indemnify any Indemnified Person for any loss,
liability or expense of any Indemnified Person not otherwise referred to in
Subsection (a) above.

             Concerning the Trustee and the Securities Administrator

         Section 10.01 DUTIES OF TRUSTEE. (a) The Trustee, prior to the
occurrence of an Event of Default and after the curing or waiver of all Events
of Default which may have occurred, and the Securities Administrator each
undertake to perform such duties and only such duties as are specifically set
forth in this Agreement as duties of the Trustee and the Securities
Administrator, respectively. If an Event of Default has occurred and has not
been cured or waived, the Trustee shall exercise such of the rights and powers
vested in it by this Agreement, and subject to Section 8.02(b) use the same
degree of care and skill in their exercise, as a prudent person would exercise
under the circumstances in the conduct of his own affairs.

         (b) Upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments which are specifically
required to be furnished to the Trustee and the Securities Administrator
pursuant to any provision of this Agreement, the Trustee and the Securities
Administrator, respectively, shall examine them to determine whether they are in
the form required by this Agreement; provided, however, that neither the Trustee
nor the Securities Administrator shall be responsible for the accuracy or
content of any resolution, certificate, statement, opinion, report, document,
order or other instrument furnished by the Servicer or the Master Servicer;
provided, further, that neither the Trustee nor the Securities Administrator
shall be responsible for the accuracy or verification of any calculation
provided to it pursuant to this Agreement.

         (c) On each Distribution Date, the Trustee shall make monthly
distributions and the final distribution to the Certificateholders from funds in
the Distribution Account as provided in Sections 6.01 and 10.01 herein based the
report of the Securities Administrator. In addition, the Trustee shall
immediately notify the Master Servicer if, on any Servicer Remittance Date, the
Servicer fails to remit to the Trustee the funds required to be remitted by the
Servicer under the Servicing Agreement.

         (d) No provision of this Agreement shall be construed to relieve the
Trustee or the Securities Administrator from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct;
provided, however, that:

                  (i) Prior to the occurrence of an Event of Default, and after
         the curing or waiver of all such Events of Default which may have
         occurred, the duties and obligations of the Trustee and the Securities
         Administrator shall be determined solely by the express provisions of
         this Agreement, neither the Trustee nor the Securities Administrator
         shall be liable except for the performance of their respective duties
         and obligations as are specifically set forth in this Agreement, no
         implied covenants or obligations shall be read into this Agreement
         against the Trustee or the Securities Administrator and, in the absence
         of bad faith on the part of the Trustee or the Securities
         Administrator, respectively, the Trustee or the Securities
         Administrator, respectively, may conclusively rely, as to the truth of
         the statements and the correctness of the opinions expressed therein,
         upon any certificates or opinions furnished to the Trustee or the
         Securities Administrator, respectively, and conforming to the
         requirements of this Agreement;

                                      -80-

<PAGE>

                  (ii) Neither the Trustee nor the Securities Administrator
         shall be liable in its individual capacity for an error of judgment
         made in good faith by a Responsible Officer or Responsible Officers of
         the Trustee or an officer of the Securities Administrator,
         respectively, unless it shall be proved that the Trustee or the
         Securities Administrator, respectively, was negligent in ascertaining
         the pertinent facts;

                  (iii) Neither the Trustee nor the Securities Administrator
         shall be liable with respect to any action taken, suffered or omitted
         to be taken by it in good faith in accordance with the directions of
         the Holders of Certificates evidencing Fractional Undivided Interests
         aggregating not less than 25% of the Trust Fund, if such action or
         non-action relates to the time, method and place of conducting any
         proceeding for any remedy available to the Trustee or the Securities
         Administrator, respectively, or exercising any trust or other power
         conferred upon the Trustee or the Securities Administrator,
         respectively, under this Agreement;

                  (iv) The Trustee shall not be required to take notice or be
         deemed to have notice or knowledge of any default or Event of Default
         unless a Responsible Officer of the Trustee's Corporate Trust Office
         shall have actual knowledge thereof. In the absence of such notice, the
         Trustee may conclusively assume there is no such default or Event of
         Default;

                  (v) The Trustee shall not in any way be liable by reason of
         any insufficiency in any Account held by or in the name of Trustee
         unless it is determined by a court of competent jurisdiction that the
         Trustee's gross negligence or willful misconduct was the primary cause
         of such insufficiency (except to the extent that the Trustee is obligor
         and has defaulted thereon);

                  (vi) Anything in this Agreement to the contrary
         notwithstanding, in no event shall the Trustee or the Securities
         Administrator be liable for special, indirect or consequential loss or
         damage of any kind whatsoever (including but not limited to lost
         profits), even if the Trustee or the Securities Administrator,
         respectively, has been advised of the likelihood of such loss or damage
         and regardless of the form of action; and

                  (vii) None of the Securities Administrator, EMC or the Trustee
         shall be responsible for the acts or omissions of the other, it being
         understood that this Agreement shall not be construed to render them
         partners, joint venturers or agents of one another.

         Neither the Trustee nor the Securities Administrator shall be required
to expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if there is reasonable ground for believing that the repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it, and none of the provisions contained in this Agreement
shall in any event require the Trustee or the Securities Administrator to
perform, or be responsible for the manner of performance of, any of the
obligations of the Servicer under the Servicing Agreement or the Master Servicer
under the Agreement, except during such time, if any, as the Trustee shall be
the successor to, and be vested with the rights, duties, powers and privileges
of, the Master Servicer in accordance with the terms of this Agreement.

the Distribution Account pursuant to this Agreement will be promptly so
deposited by the Trustee.

         (f) Except for those actions that the Trustee or the Securities
Administrator is required to take hereunder, neither the Trustee nor the

         Section 10.02 CERTAIN MATTERS AFFECTING THE TRUSTEE AND THE SECURITIES
ADMINISTRATOR. Except as otherwise provided in Section 9.01:

                  (i) The Trustee and the Securities Administrator may rely and
         shall be protected in acting or refraining from acting in reliance on
         any resolution, certificate of a Seller, Master Servicer or Servicer,
         certificate of auditors or any other certificate, statement,
         instrument, opinion, report, notice, request, consent, order,
         appraisal, bond or other paper or document believed by it to be genuine
         and to have been signed or presented by the proper party or parties;

                  (ii) The Trustee and the Securities Administrator may consult
         with counsel and any advice of such counsel or any Opinion of Counsel
         shall be full and complete authorization and protection with respect to
         any action taken or suffered or omitted by it hereunder in good faith
         and in accordance with such advice or Opinion of Counsel:

                  (iii) Neither the Trustee nor the Securities Administrator
         shall be under any obligation to exercise any of the trusts or powers
         vested in it by this Agreement, other than its obligation to give
         notices pursuant to this Agreement, or to institute, conduct or defend
         any litigation hereunder or in relation hereto at the request, order or
         direction of any of the Certificateholders pursuant to the provisions
         of this Agreement, unless such Certificateholders shall have offered to
         the Trustee reasonable security or indemnity against the costs,
         expenses and liabilities which may be incurred therein or thereby.
         Nothing contained herein shall, however, relieve the Trustee of the
         obligation, upon the occurrence of an Event of Default of which a
         Responsible Officer of the Trustee's Corporate Trust Office has actual
         knowledge (which has not been cured or waived), subject to Section
         8.02(b), to exercise such of the rights and powers vested in it by this
         Agreement, and to use the same degree of care and skill in their
         exercise, as a prudent person would exercise under the circumstances in
         the conduct of his own affairs;

                  (iv) Prior to the occurrence of an Event of Default hereunder
         and after the curing or waiver of all Events of Default which may have
         occurred, neither the Trustee nor the Securities Administrator shall be
         liable in its individual capacity for any action taken, suffered or
         omitted by it in good faith and believed by it to be authorized or
         within the discretion or rights or powers conferred upon it by this
         Agreement;

                  (v) Neither the Trustee nor the Securities Administrator shall
         be bound to make any investigation into the facts or matters stated in
         any resolution, certificate, statement, instrument, opinion, report,
         notice, request, consent, order, approval, bond or other paper or

                                      -82-

         document, unless requested in writing to do so by Holders of
         Certificates evidencing Fractional Undivided Interests aggregating not
         less than 25% of the Trust Fund and provided that the payment within a
         reasonable time to the Trustee or the Securities Administrator, as
         applicable, of the costs, expenses or liabilities likely to be incurred
         by it in the making of such investigation is, in the opinion of the
         Trustee or the Securities Administrator, as applicable, reasonably
         assured to the Trustee or the Securities Administrator, as applicable,
         by the security afforded to it by the terms of this Agreement. The
         Trustee or the Securities Administrator may require reasonable
         indemnity against such expense or liability as a condition to taking
         any such action. The reasonable expense of every such examination shall
         be paid by the Certificateholders requesting the investigation;

                  (vi) The Trustee and the Securities Administrator may execute
         any of the trusts or powers hereunder or perform any duties hereunder
         either directly or through Affiliates, agents or attorneys; provided,
         however, that the Trustee may not appoint any agent to perform its
         custodial functions with respect to the Mortgage Files or paying agent
         functions under this Agreement without the express written consent of
         EMC, which consent will not be unreasonably withheld. Neither the
         Trustee nor the Securities Administrator shall be liable or responsible
         for the misconduct or negligence of any of the Trustee's or the
         Securities Administrator's agents or attorneys or a custodian or paying
         agent appointed hereunder by the Trustee or the Securities
         Administrator with due care and, when required, with the consent of the
         EMC;

                  (vii) Should the Trustee or the Securities Administrator deem
         the nature of any action required on its part, other than a payment or
         transfer under Subsection 4.01(b) or Section 4.02, to be unclear, the
         Trustee or the Securities Administrator, respectively, may require
         prior to such action that it be provided by the Seller with reasonable
         further instructions;

                  (viii) The right of the Trustee or the Securities
         Administrator to perform any discretionary act enumerated in this
         Agreement shall not be construed as a duty, and neither the Trustee nor
         the Securities Administrator shall be accountable for other than its
         negligence or willful misconduct in the performance of any such act;

                  (ix) Neither the Trustee nor the Securities Administrator
         shall be required to give any bond or surety with respect to the
         execution of the trust created hereby or the powers granted hereunder,
         except as provided in Subsection 9.07; and

                  (x) Neither the Trustee nor the Securities Administrator shall
         have any duty to conduct any affirmative investigation as to the
         occurrence of any condition requiring the repurchase of any Mortgage
         Loan by the Mortgage Loan Seller pursuant to the Mortgage Loan Purchase
         Agreement or this Agreement, as applicable, or the eligibility of any
         Mortgage Loan for purposes of this Agreement.

CERTIFICATES OR MORTGAGE LOANS. The recitals contained herein and in the
Certificates (other than the signature and countersignature of the Trustee on
the Certificates) shall be taken as the statements of the Seller, and neither
the Trustee nor the Securities Administrator shall have any responsibility for
their correctness. Neither the Trustee nor the Securities Administrator makes
any representation as to the validity or sufficiency of the Certificates (other
than the signature and countersignature of the Trustee on the Certificates) or
of any Mortgage Loan except as expressly provided in Sections 2.02 and 2.05
hereof; provided, however, that the foregoing shall not relieve the Trustee of
the obligation to review the Mortgage Files pursuant to Sections 2.02 and 2.04.
The Trustee's signature and countersignature (or countersignature of its agent)
on the Certificates shall be solely in its capacity as Trustee and shall not
constitute the Certificates an obligation of the Trustee in any other capacity.
Neither the Trustee nor the Securities Administrator shall be accountable for
the use or application by the Seller of any of the Certificates or of the
proceeds of such Certificates, or for the use or application of any funds paid
to the Seller with respect to the Mortgage Loans. Subject to the provisions of
Section 2.05, neither the Trustee nor the Securities Administrator shall be
responsible for the legality or validity of this Agreement or any document or
instrument relating to this Agreement, the validity of the execution of this
Agreement or of any supplement hereto or instrument of further assurance, or the
validity, priority, perfection or sufficiency of the security for the
Certificates issued hereunder or intended to be issued hereunder. Neither the
Trustee nor the Securities Administrator shall at any time have any
responsibility or liability for or with respect to the legality, validity and
enforceability of any Mortgage or any Mortgage Loan, or the perfection and
priority of any Mortgage or the maintenance of any such perfection and priority,
or for or with respect to the sufficiency of the Trust Fund or its ability to
generate the payments to be distributed to Certificateholders, under this
Agreement. Neither the Trustee nor the Securities Administrator shall have any
responsibility for filing any financing or continuation statement in any public
office at any time or to otherwise perfect or maintain the perfection of any
security interest or lien granted to it hereunder or to record this Agreement
other than any continuation statements filed by the Trustee pursuant to Section
3.07.

         Section 10.04 TRUSTEE AND SECURITIES ADMINISTRATOR MAY OWN
CERTIFICATES. The Trustee and the Securities Administrator in its individual
capacity or in any capacity other than as Trustee hereunder may become the owner
or pledgee of any Certificates with the same rights it would have if it were not

with the parties hereto.

         Section 10.05 TRUSTEE'S AND SECURITIES ADMINISTRATOR'S FEES AND
EXPENSES. The fees and expenses of the Trustee and the Securities Administrator
shall be paid in accordance with a side letter agreement. In addition, the
Trustee and the Securities Administrator will be entitled to recover from the

Securities Administrator, respectively, in connection with any Event of Default,
any breach of this Agreement or any claim or legal action (including any pending
or threatened claim or legal action) incurred or made by the Trustee or the
Securities Administrator, respectively, in the administration of the trusts
hereunder (including the reasonable compensation, expenses and disbursements of
its counsel) except any such expense, disbursement or advance as may arise from
its negligence or intentional misconduct or which is the responsibility of the
Certificateholders or the Trust Fund hereunder. If funds in the Distribution
Account are insufficient therefor, the Trustee and the Securities Administrator
shall

                                      -84-

<PAGE>

recover such expenses from the Seller. Such compensation and reimbursement
obligation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust.

         Section 10.06 ELIGIBILITY REQUIREMENTS FOR TRUSTEE AND SECURITIES
ADMINISTRATOR. The Trustee and any successor Trustee and the Securities
Administrator and any successor Securities Administrator shall during the entire
duration of this Agreement be a state bank or trust company or a national
banking association organized and doing business under the laws of such state or
the United States of America, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus and undivided profits of at
least $40,000,000 or, in the case of a successor Trustee, $50,000,000, subject
to supervision or examination by federal or state authority and, in the case of
the Trustee, rated "BBB" or higher by Fitch with respect to their long-term
rating and rated "BBB" or higher by Standard & Poor's and "Baa2" or higher by

and, in the case of a successor Trustee or successor Securities Administrator
other than pursuant to Section 9.10, rated in one of the two highest long-term
debt categories of, or otherwise acceptable to, each of the Rating Agencies. If
the Trustee publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then
for the purposes of this Section 9.06 the combined capital and surplus of such
corporation shall be deemed to be its total equity capital (combined capital and
surplus) as set forth in its most recent report of condition so published. In
case at any time the Trustee or the Securities Administrator shall cease to be
eligible in accordance with the provisions of this Section 9.06, the Trustee or
the Securities Administrator shall resign immediately in the manner and with the

in amounts, with standard coverage and subject to deductibles, as are customary
for insurance typically maintained by banks or their affiliates which act as
custodians for investor-owned mortgage pools. A certificate of an officer of the
Trustee or the Securities Administrator as to the Trustee's or the Securities
Administrator's, respectively, compliance with this Section 9.07 shall be
furnished to any Certificateholder upon reasonable written request.

         Section 10.08 RESIGNATION AND REMOVAL OF THE TRUSTEE AND SECURITIES
ADMINISTRATOR. (a) The Trustee and the Securities Administrator may at any time
resign and be discharged from the Trust hereby created by giving written notice
thereof to the Seller, the Master Servicer and the Servicer, with a copy to the
Rating Agencies. Upon receiving such notice of resignation, the Seller shall
promptly appoint a successor Trustee or successor Securities Administrator, as
applicable, by written instrument, in triplicate, one copy of which instrument
shall be delivered to each of the resigning Trustee or Securities Administrator,
as applicable, the successor Trustee or Securities Administrator, as applicable.
If no successor Trustee or Securities Administrator shall have been so appointed
and have accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee or Securities Administrator may petition any
court of competent jurisdiction for the appointment of a successor Trustee or
Securities Administrator.

         (b) If at any time the Trustee or the Securities Administrator shall
cease to be eligible in accordance with the provisions of Section 9.06 and shall
fail to resign after written request therefor by the Seller or if at any time

or any public officer shall take charge or control of the Trustee or the
Securities Administrator, as applicable, or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation, then the Seller shall
promptly remove the Trustee, or shall be entitled to remove the Securities
Administrator, as applicable, and appoint a successor Trustee or Securities

the Trustee or the Securities Administrator and appoint a successor Trustee or
Securities Administrator by written instrument or instruments, in quadruplicate,
signed by such Holders or their attorneys-in-fact duly authorized, one complete
set of which instruments shall be delivered to the Seller, the Master Servicer,

Securities Administrator is removed), and the Trustee or Securities
Administrator so removed and the successor so appointed.

         Section 10.09 SUCCESSOR TRUSTEE AND SUCCESSOR SECURITIES ADMINISTRATOR.
(a) Any successor Trustee or Securities Administrator appointed as provided in
Section 9.08 shall execute, acknowledge and deliver to the Seller and to its
predecessor Trustee or Securities Administrator an instrument accepting such
appointment hereunder. The resignation or removal of the predecessor Trustee or
Securities Administrator shall then become effective and such successor Trustee
or Securities Administrator, without any further act, deed or conveyance, shall
become fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as Trustee or
Securities Administrator herein. The predecessor Trustee or Securities
Administrator shall after payment of its outstanding fees and expenses promptly
deliver to the successor Trustee or Securities Administrator, as applicable, all
assets and records of the Trust held by it hereunder, and the Seller and the
predecessor Trustee or Securities Administrator, as applicable, shall execute

required for more fully and certainly vesting and confirming in the successor
Trustee or Securities Administrator, as applicable, all such rights, powers,
duties and obligations.

appointment as provided in this Section 9.09 unless at the time of such

under the provisions of Section 9.06.

Administrator as provided in this Section 9.09, the successor Trustee or
Securities Administrator shall mail notice of the succession of such Trustee or
Securities Administrator hereunder to all Certificateholders at their addresses
as shown in the Certificate Register and to the Rating Agencies. EMC shall pay
the cost of any mailing by the successor Trustee or Securities Administrator.

         Section 10.10 MERGER OR CONSOLIDATION OF TRUSTEE OR SECURITIES
ADMINISTRATOR. Any state bank or trust company or national banking association
into which the Trustee or the Securities Administrator may be merged or
converted or with which it may be consolidated or any state bank or trust
company or national banking association resulting from any merger, conversion or
consolidation to which the Trustee or the Securities Administrator,
respectively, shall be a party, or any state bank or trust company or national
banking association succeeding to all or substantially all of the corporate
trust business of the Trustee or the Securities Administrator, respectively,
shall be the successor of the Trustee or the Securities Administrator,
respectively, hereunder, provided such state bank or trust company or national
banking association shall be eligible under the provisions of Section 9.06. Such
succession shall be valid without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding.

         Section 10.11 APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE. (a)
Notwithstanding any other provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any part of the
Trust or property constituting the same may at the time be located, the Seller
and the Trustee acting jointly shall have the power and shall execute and
deliver all instruments to appoint one or more Persons approved by the Trustee
and the Seller to act as cotrustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust, and to
vest in such Person or Persons, in such capacity, such title to the Trust, or
any part thereof, and, subject to the other provisions of this Section 9.11,
such powers, duties, obligations, rights and trusts as the Seller and the
Trustee may consider necessary or desirable.

         (b) If the Seller shall not have joined in such appointment within 15
days after the receipt by it of a written request so to do, the Trustee shall
have the power to make such appointment without the Seller.

         (c) No co-trustee or separate trustee hereunder shall be required to
meet the terms of eligibility as a successor Trustee under Section 9.06
hereunder and no notice to Certificateholders of the appointment of
co-trustee(s) or separate trustee(s) shall be required under Section 9.08
hereof.

         (d) In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 9.11, all rights, powers, duties and obligations
conferred or imposed upon the Trustee and required to be conferred on such
co-trustee shall be conferred or imposed upon and exercised or performed by the
Trustee and such separate trustee or co-trustee jointly, except to the extent
that under any law of any jurisdiction in which any particular act or acts are
to be performed (whether as Trustee hereunder or as successor to the Master
Servicer hereunder), the Trustee shall be incompetent or unqualified to perform
such act or acts, in which event such rights, powers, duties and obligations
(including the holding of title to the Trust or any portion thereof in any such
jurisdiction) shall be exercised and performed by such separate trustee or
co-trustee at the direction of the Trustee.

                                      -87-

<PAGE>

         (e) Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article IX. Each separate trustee and co-trustee, upon its acceptance of
the trusts conferred, shall be vested with the estates or property specified in
its instrument of appointment, either jointly with the Trustee or separately, as
may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee. Every
such instrument shall be filed with the Trustee.

         (f) To the extent not prohibited by law, any separate trustee or
co-trustee may, at any time, request the Trustee, its agent or attorney-in-fact,
with full power and authority, to do any lawful act under or with respect to
this Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties rights, remedies and trusts shall vest in and be
exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor Trustee.

         (g) No trustee under this Agreement shall be personally liable by
reason of any act or omission of another trustee under this Agreement. The
Seller and the Trustee acting jointly may at any time accept the resignation of
or remove any separate trustee or co-trustee.

         Section 10.12 FEDERAL INFORMATION RETURNS AND REPORTS TO
CERTIFICATEHOLDERS; REMIC ADMINISTRATION. (a) For federal income tax purposes,
the taxable year of each of REMIC I and REMIC II shall be a calendar year and
the Securities Administrator shall maintain or cause the maintenance of the
books of each such REMIC on the accrual method of accounting.

         (b) The Securities Administrator shall prepare and file or cause to be
filed with the Internal Revenue Service, and the Trustee shall sign, Federal tax
information returns or elections required to be made hereunder with respect to
each of REMIC I and REMIC II, the Trust Fund, if applicable, and the
Certificates containing such information and at the times and in the manner as
may be required by the Code or applicable Treasury regulations, and shall
furnish to each Holder of Certificates at any time during the calendar year for
which such returns or reports are made such statements or information at the
times and in the manner as may be required thereby, including, without
limitation, reports relating to interest, original issue discount and market
discount or premium (using a constant prepayment assumption of 25% CPR). The
Securities Administrator will apply for an Employee Identification Number from
the IRS under Form SS-4 or any other acceptable method for all tax entities. In
connection with the foregoing, the Securities Administrator shall timely prepare
and file, and the Trustee shall sign, IRS Form 8811, which shall provide the
name and address of the person who can be contacted to obtain information
required to be reported to the holders of regular interests in each of REMIC I
and REMIC II (the "REMIC Reporting Agent"). The Trustee shall make elections to
treat each of REMIC I and REMIC II as a REMIC (which elections shall apply to
the taxable period ending December 31, 2002 and each calendar year thereafter)
in such manner as the Code or applicable Treasury regulations may prescribe, and
as described by the Securities Administrator. The Trustee shall sign all tax
information returns filed pursuant to this Section and any other returns as may
be required by the Code. The Holder of the Class R-I

                                      -88-

<PAGE>

Certificate is hereby designated as the "Tax Matters Person" (within the meaning
of Treas. Reg. ss.ss.1.860F-4(d)) for REMIC I, and the Holder of the Class R-II
Certificate is hereby designated as the "Tax Matters Person" for REMIC II. The
Securities Administrator is hereby designated and appointed as the agent of each
such Tax Matters Person. Any Holder of a Residual Certificate will by acceptance
thereof appoint the Securities Administrator as agent and attorney-in-fact for
the purpose of acting as Tax Matters Person for each of REMIC I and REMIC II
during such time as the Securities Administrator does not own any such Residual
Certificate. In the event that the Code or applicable Treasury regulations
prohibit the Trustee from signing tax or information returns or other
statements, or the Securities Administrator from acting as agent for the Tax
Matters Person, the Trustee and the Securities Administrator shall take whatever
action that in its sole good faith judgment is necessary for the proper filing
of such information returns or for the provision of a tax matters person,
including designation of the Holder of a Residual Certificate to sign such
returns or act as tax matters person. Each Holder of a Residual Certificate
shall be bound by this Section.

         (c) The Securities Administrator shall provide upon request and receipt
of reasonable compensation, such information as required in Section
860D(a)(6)(B) of the Code to the Internal Revenue Service, to any Person
purporting to transfer a Residual Certificate to a Person other than a
transferee permitted by Section 5.05(b), and to any regulated investment
company, real estate investment trust, common trust fund, partnership, trust,
estate, organization described in Section 1381 of the Code, or nominee holding
an interest in a pass-through entity described in Section 860E(e)(6) of the
Code, any record holder of which is not a transferee permitted by Section
5.05(b) (or which is deemed by statute to be an entity with a disqualified
member).

         (d) The Securities Administrator shall prepare and file or cause to be
filed, and the Trustee shall sign, any state income tax returns required under
Applicable State Law with respect to each of REMIC I and REMIC II or the Trust
Fund.

         (e) Notwithstanding any other provision of this Agreement, the Trustee
and the Securities Administrator shall comply with all federal withholding
requirements respecting payments to Certificateholders of interest or original
issue discount on the Mortgage Loans, that the Trustee or the Securities
Administrator reasonably believes are applicable under the Code. The consent of
Certificateholders shall not be required for such withholding. In the event the
Trustee or the Securities Administrator withholds any amount from interest or
original issue discount payments or advances thereof to any Certificateholder
pursuant to federal withholding requirements, the Trustee or the Securities
Administrator shall, together with its monthly report to such
Certificateholders, indicate such amount withheld.

         (f) The Trustee and the Securities Administrator agree to indemnify the
Trust Fund and the Seller for any taxes and costs including, without limitation,
any reasonable attorneys fees imposed on or incurred by the Trust Fund, the
Seller or the Master Servicer, as a result of a breach of the Trustee's
covenants and the Securities Administrator's covenants, respectively, set forth
in this Section 9.12; provided, however, such liability and obligation to
indemnify in this paragraph shall not be joint and several and neither the
Trustee nor the Securities Administrator shall be liable or be obligated to
indemnify the Trust Fund for the failure by the other to perform any duty under
this Agreement or the breach by the other of any covenant in this Agreement.

         Section 11.01 TERMINATION UPON REPURCHASE BY THE SELLER OR ITS DESIGNEE
OR LIQUIDATION OF THE MORTGAGE LOANS.

         (a) Subject to Section 10.02, the respective obligations and
responsibilities of the Seller, the Trustee, the Master Servicer and the
Securities Administrator created hereby, other than the obligation of the
Trustee to make payments to Certificateholders as hereinafter set forth shall
terminate upon:

                  (i) the repurchase by or at the direction of the Seller or its
         designee of all Mortgage Loans and all related REO Property remaining
         in the Trust at a price equal to (a) 100% of the Outstanding Principal
         Balance of each Mortgage Loan (other than a Mortgage Loan related to
         REO Property) as of the date of repurchase, net of the principal
         portion of any unreimbursed Monthly Advances made by the purchaser,
         together with interest at the applicable Mortgage Interest Rate accrued
         but unpaid to, but not including, the first day of the month of
         repurchase, plus (b) the appraised value of any related REO Property,
         less the good faith estimate of the Seller of liquidation expenses to
         be incurred in connection with its disposal thereof (but not more than
         the Outstanding Principal Balance of the related Mortgage Loan,
         together with interest at the applicable Mortgage Interest Rate accrued
         on that balance but unpaid to, but not including, the first day of the
         month of repurchase), such appraisal to be calculated by an appraiser
         mutually agreed upon by the Seller and the Trustee at the expense of
         the Seller; or

                  (ii) the later of the making of the final payment or other
         liquidation, or any advance with respect thereto, of the last Mortgage
         Loan remaining in the Trust Fund or the disposition of all property
         acquired with respect to any Mortgage Loan; provided, however, that in
         the event that an advance has been made, but not yet recovered, at the
         time of such termination, the Person having made such advance shall be
         entitled to receive, notwithstanding such termination, any payments
         received subsequent thereto with respect to which such advance was
         made; or

                  (iii) the payment to Certificateholders of all amounts
         required to be paid to them pursuant to this Agreement.

         (b) In no event, however, shall the Trust created hereby continue
beyond the expiration of 21 years from the death of the last survivor of the
descendants of Joseph P. Kennedy, the late Ambassador of the United States to
the Court of St. James's, living on the date of this Agreement.

         (c) The right of the Seller or its designee to repurchase all the
Mortgage Loans pursuant to Subsection 10.01(a)(i) above shall be exercisable
only if (i) the aggregate Scheduled Principal Balance of the Mortgage Loans at
the time of any such repurchase is less than 10% of the Cut-off Date Balance or
(ii) the Seller, based upon an Opinion of Counsel, has determined that the REMIC
status of the REMIC I or REMIC II has been lost or that a substantial risk
exists that such REMIC

                                      -90-

<PAGE>

status will be lost for the then-current taxable year. At any time thereafter,
in the case of (i) or (ii) above, the Seller may elect to terminate the REMIC I
or REMIC II at any time, and upon such election, the Seller or its designee,
shall repurchase all the Mortgage Loans.

         (d) The Trustee shall give notice of any termination to the
Certificateholders, with a copy to the Master Servicer, the Securities
Administrator and the Rating Agencies, upon which the Certificateholders shall
surrender their Certificates to the Trustee for payment of the final
distribution and cancellation. Such notice shall be given by letter, mailed not
earlier than the l5th day and not later than the 25th day of the month next
preceding the month of such final distribution, and shall specify (i) the
Distribution Date upon which final payment of the Certificates will be made upon
presentation and surrender of the Certificates at the office of the Trustee
therein designated, (ii) the amount of any such final payment and (iii) that the
Record Date otherwise applicable to such Distribution Date is not applicable,
payments being made only upon presentation and surrender of the Certificates at
the office of the Trustee therein specified.

         (e) If the option of the Seller to repurchase or cause the repurchase
of all the Mortgage Loans under Subsection 10.01 (a)(i) above is exercised, the
Seller and/or its designee shall deliver to the Trustee for deposit in the
Distribution Account, by the Business Day prior to the applicable Distribution
Date, an amount equal to the repurchase price for the Mortgage Loans being
purchased by it and all property acquired with respect to such Mortgage Loans
remaining in REMIC I and REMIC II. Upon presentation and surrender of the
Certificates by the Certificateholders, the Trustee shall distribute to the
Certificateholders an amount determined as follows: with respect to each
Certificate (other than the Class R Certificates), the outstanding Current
Principal Amount, plus with respect to each Certificate (other than the Class R
Certificates), one month's interest thereon at the applicable Pass-Through Rate;
and with respect to the Class R Certificates, the percentage interest evidenced
thereby multiplied by the difference, if any, between the above described
repurchase price and the aggregate amount to be distributed to the Holders of
the Certificates (other than the Class R Certificates). If the proceeds with
respect to the Group I Mortgage Loans are not sufficient to pay all of the Group
I Certificates in full, any such deficiency will be allocated first, to the
Subordinate Certificates, in inverse order of their numerical designation, and
then to the Group I Senior Certificates on a pro rata basis. If the proceeds
with respect to the Group II Mortgage Loans are not sufficient to pay all of the
Group II Certificates in full, any such deficiency will be allocated first, to
the Subordinate Certificates, in inverse order of their numerical designation,
and then to the Group II Senior Certificates on a pro rata basis. Upon deposit
of the required repurchase price and following such final Distribution Date, the
Trustee shall release promptly to the Seller and/or its designee the Mortgage
Files for the remaining applicable Mortgage Loans, and the Accounts with respect
thereto shall terminate, subject to the Trustee's obligation to hold any amounts
payable to Certificateholders in trust without interest pending final
distributions pursuant to Subsection 10.01(g). Any other amounts remaining in
the Accounts will belong to the Seller. Upon deposit of the required repurchase
price and following such final Distribution Date, the Trustee shall release
promptly to the Seller and/or its designee, as the case may be, the Mortgage
Files for the remaining Mortgage Loans, and the Accounts with respect thereto
shall terminate, subject to the Trustee's obligation to hold any amounts payable
to Certificateholders in trust without interest pending final distributions
pursuant to Subsection 10.01(g).

                                      -91-

<PAGE>

         (f) In the event that this Agreement is terminated by reason of the
payment or liquidation of all Mortgage Loans or the disposition of all property
acquired with respect to all Mortgage Loans under Subsection 10.01(a)(ii) above,
upon the presentation and surrender of the Certificates, the Trustee shall
distribute to the remaining Certificateholders, in accordance with their
respective interests, all distributable amounts remaining in the Distribution
Account. Upon remittance to the Trustee by the Servicer of such distributable
amounts, and following such final Distribution Date, the Trustee shall release
promptly to the Seller or its designee the Mortgage Files for the remaining
Mortgage Loans, and the Distribution Account shall terminate, subject to the
Trustee's obligation to hold any amounts payable to the Certificateholders in
trust without interest pending final distributions pursuant to this Subsection
10.01(g).

         (g) If not all of the Certificateholders shall surrender their
Certificates for cancellation within six months after the time specified in the
above-mentioned written notice, the Trustee shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice, not all the Certificates shall have been
surrendered for cancellation, the Trustee may take appropriate steps, or appoint
any agent to take appropriate steps, to contact the remaining Certificateholders
concerning surrender of their Certificates, and the cost thereof shall be paid
out of the funds and other assets which remain subject to this Agreement.

         Section 11.02 ADDITIONAL TERMINATION REQUIREMENTS. (a) If the option of
the Seller to repurchase all the Mortgage Loans under Subsection 10.01(a)(i)
above is exercised, the Trust Fund and each of REMIC I and REMIC II shall be
terminated in accordance with the following additional requirements, unless the
Trustee has been furnished with an Opinion of Counsel to the effect that the
failure of the Trust to comply with the requirements of this Section 10.02 will
not (i) result in the imposition of taxes on "prohibited transactions" as
defined in Section 860F of the Code on each of REMIC I and REMIC II or (ii)
cause any REMIC to fail to qualify as a REMIC at any time that any Regular
Certificates are outstanding:

                  (i) within 90 days prior to the final Distribution Date, at
         the written direction of the Seller, the Trustee, as agent for the
         respective Tax Matters Persons, shall adopt a plan of complete
         liquidation of REMIC I and REMIC II in the case of a termination under
         Subsection 10.01(a)(i), or a plan of complete liquidation of REMIC I in
         the case of a termination under Subsection 10.01(c), provided to it by
         the Seller meeting the requirements of a "qualified liquidation" under
         Section 860F of the Code and any regulations thereunder.

                  (ii) the Seller shall notify the Trustee at the commencement
         of such 90-day liquidation period and, at or prior to the time of
         making of the final payment on the Certificates, the Trustee shall sell
         or otherwise dispose of all of the remaining assets of the Trust Fund
         in accordance with the terms hereof; and

                  (iii) at or after the time of adoption of such a plan of
         complete liquidation of any of REMIC I and REMIC II and at or prior to
         the final Distribution Date, the Trustee shall sell for cash all of the
         assets of the Trust to or at the direction of the Seller, and REMIC I
         and REMIC II, as applicable, shall terminate at such time.

                                      -92-

<PAGE>

         (b) By their acceptance of the Residual Certificates, the Holders
thereof hereby (i) agree to adopt such a plan of complete liquidation of the
REMIC upon the written request of the Seller, and to take such action in
connection therewith as may be reasonably requested by the Seller and (ii)
appoint the Seller as their attorney-in-fact, with full power of substitution,
for purposes of adopting such a plan of complete liquidation. The Trustee shall
adopt such plan of liquidation by filing the appropriate statement on the final
tax return of each REMIC. Upon complete liquidation or final distribution of all
of the assets of the Trust Fund, the Trust Fund and each of REMIC I and REMIC II
shall terminate.

                            Miscellaneous Provisions

         Section 12.01 INTENT OF PARTIES. The parties intend that each of REMIC
I and REMIC II shall be treated as a REMIC for federal income tax purposes and
that the provisions of this Agreement should be construed in furtherance of this
intent.

         Section 12.02 AMENDMENT. (a) This Agreement may be amended from time to
time by EMC, the Seller, the Master Servicer, the Securities Administrator and
the Trustee, and the Servicing Agreement may be amended from time to time by
EMC, the Servicer, the Master Servicer and the Trustee, without notice to or the
consent of any of the Certificateholders, to cure any ambiguity, to correct or
supplement any provisions herein or therein that may be defective or
inconsistent with any other provisions herein or therein, to comply with any
changes in the Code or to make any other provisions with respect to matters or
questions arising under this Agreement which shall not be inconsistent with the
provisions of this Agreement; provided, however, that such action shall not, as
evidenced by an Opinion of Independent Counsel, addressed to the Trustee,
adversely affect in any material respect the interests of any Certificateholder.

         (b) This Agreement may also be amended from time to time by EMC, the
Master Servicer, the Seller, the Securities Administrator and the Trustee, and
the Servicing Agreement may also be amended from time to time by EMC, the
Servicer, the Master Servicer and the Trustee, with the consent of the Holders
of Certificates evidencing Fractional Undivided Interests aggregating not less
than 51% of the Trust Fund or of the applicable Class or Classes, if such
amendment affects only such Class or Classes, for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Agreement or of modifying in any manner the rights of the
Certificateholders; provided, however, that no such amendment shall (i) reduce
in any manner the amount of, or delay the timing of, payments received on
Mortgage Loans which are required to be distributed on any Certificate without
the consent of the Holder of such Certificate, (ii) reduce the aforesaid
percentage of Certificates the Holders of which are required to consent to any
such amendment, without the consent of the Holders of all Certificates then
outstanding, or (iii) cause REMIC I or REMIC II to fail to qualify as a REMIC
for federal income tax purposes, as evidenced by an Opinion of Independent
Counsel which shall be provided to the Trustee other than at the Trustee's
expense. Notwithstanding any other provision of this Agreement, for purposes of
the giving or withholding of consents pursuant to Section 11.02(b), Certificates
registered in the name of or held for the benefit of the Seller, the Securities
Administrator, the Master Servicer or the Trustee or any Affiliate thereof shall
be entitled to vote their Fractional Undivided Interests with respect to matters
affecting such Certificates.

         (c) Promptly after the execution of any such amendment, the Trustee
shall furnish a copy of such amendment or written notification of the substance
of such amendment to each Certificateholder, with a copy to the Rating Agencies.

         (d) In the case of an amendment under Subsection 11.02(b) above, it
shall not be necessary for the Certificateholders to approve the particular form
of such an amendment. Rather, it shall be sufficient if the Certificateholders
approve the substance of the amendment. The manner of obtaining

                                      -94-

<PAGE>

such consents and of evidencing the authorization of the execution thereof by
Certificateholders shall be subject to such reasonable regulations as the
Trustee may prescribe.

         (e) Prior to the execution of any amendment to this Agreement, the
Trustee shall be entitled to receive and rely upon an Opinion of Counsel stating
that the execution of such amendment is authorized or permitted by this
Agreement. The Trustee, the Master Servicer and the Securities Administrator
may, but shall not be obligated to, enter into any such amendment which affects
the Trustee's or the Securities Administrator's own respective rights, duties or
immunities under this Agreement.

         Section 12.03 RECORDATION OF AGREEMENT. To the extent permitted by
applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the Mortgaged Properties are situated, and
in any other appropriate public recording office or elsewhere. The Seller shall
effect such recordation, at the expense of the Trust upon the request in writing
of a Certificateholder, but only if such direction is accompanied by an Opinion
of Counsel (provided at the expense of the Certificateholder requesting
recordation) to the effect that such recordation would materially and
beneficially affect the interests of the Certificateholders or is required by
law.

         Section 12.04 LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS. (a) The death
or incapacity of any Certificateholder shall not terminate this Agreement or the
Trust, nor entitle such Certificateholder's legal representatives or heirs to
claim an accounting or to take any action or proceeding in any court for a
partition or winding up of the Trust, nor otherwise affect the rights,
obligations and liabilities of the parties hereto or any of them.

         (b) Except as expressly provided in this Agreement, no
Certificateholders shall have any right to vote or in any manner otherwise
control the operation and management of the Trust, or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Certificates, be construed so as to establish the Certificateholders from
time to time as partners or members of an association; nor shall any
Certificateholders be under any liability to any third Person by reason of any
action taken by the parties to this Agreement pursuant to any provision hereof.

         (c) No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon, under or with respect to this Agreement against the
Seller, the Master Servicer, the Securities Administrator or any successor to
any such parties unless (i) such Certificateholder previously shall have given
to the Trustee a written notice of a continuing default, as herein provided,
(ii) the Holders of Certificates evidencing Fractional Undivided Interests
aggregating not less than 51% of the Trust Fund shall have made written request
upon the Trustee to institute such action, suit or proceeding in its own name as
Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs and expenses and liabilities to be
incurred therein or thereby, and (iii) the Trustee, for 60 days after its
receipt of such notice, request and offer of indemnity, shall have neglected or
refused to institute any such action, suit or proceeding.

         (d) No one or more Certificateholders shall have any right by virtue of
any provision of this Agreement to affect the rights of any other
Certificateholders or to obtain or seek to obtain

                                      -95-

<PAGE>

priority or preference over any other such Certificateholder, or to enforce any
right under this Agreement, except in the manner herein provided and for the
equal, ratable and common benefit of all Certificateholders. For the protection
and enforcement of the provisions of this Section 11.04, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

         Section 12.05 ACTS OF CERTIFICATEHOLDERS. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Agreement to be given or taken by Certificateholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Certificateholders in person or by an agent duly appointed in writing.
Except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is expressly required, to the Seller. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Agreement and conclusive in favor of the Trustee and the Seller,
if made in the manner provided in this Section 11.05.

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his or her individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his or her authority. The fact and date of the execution of any such
instrument or writing, or the authority of the individual executing the same,
may also be proved in any other manner which the Trustee deems sufficient.

         (c) The ownership of Certificates (notwithstanding any notation of
ownership or other writing on such Certificates, except an endorsement in
accordance with Section 5.02 made on a Certificate presented in accordance with
Section 5.04) shall be proved by the Certificate Register, and neither the
Trustee, the Securities Administrator, the Seller, the Master Servicer nor any
successor to any such parties shall be affected by any notice to the contrary.

         (d) Any request, demand, authorization, direction, notice, consent,
waiver or other action of the holder of any Certificate shall bind every future
holder of the same Certificate and the holder of every Certificate issued upon
the registration of transfer or exchange thereof, if applicable, or in lieu
thereof with respect to anything done, omitted or suffered to be done by the
Trustee, the Securities Administrator, the Seller, the Master Servicer or any
successor to any such party in reliance thereon, whether or not notation of such
action is made upon such Certificates.

         (e) In determining whether the Holders of the requisite percentage of
Certificates evidencing Fractional Undivided Interests have given any request,
demand, authorization, direction, notice, consent or waiver hereunder,
Certificates owned by the Trustee, the Securities Administrator, the Seller, the
Master Servicer or any Affiliate thereof shall be disregarded, except as
otherwise provided in Section 11.02(b) and except that, in determining whether
the Trustee shall be protected in relying upon any such request, demand,
authorization, direction, notice, consent or waiver, only Certificates which the
Trustee knows to be so owned shall be so disregarded. Certificates which have
been pledged in good faith to the Trustee, the Securities Administrator, the
Seller, the Master

                                      -96-

<PAGE>

Servicer or any Affiliate thereof may be regarded as outstanding if the pledgor
establishes to the satisfaction of the Trustee the pledgor's right to act with
respect to such Certificates and that the pledgor is not an Affiliate of the
Trustee, the Securities Administrator, the Seller, the Master Servicer, as the
case may be.

         Section 12.06 GOVERNING LAW. THIS AGREEMENT AND THE CERTIFICATES SHALL
BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
REFERENCE TO ITS CONFLICT OF LAWS RULES AND THE OBLIGATIONS, RIGHTS AND REMEDIES
OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

                                  SERIES 2002-1

         evidencing a fractional undivided interest in the distributions
         allocable to the Class [I_-A-__] [I-X] Certificates with respect to a
         Trust Fund consisting primarily of a pool of conventional one- to
         four-family adjustable rate mortgage loans sold by STRUCTURED ASSET
         MORTGAGE INVESTMENTS INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Structured
Asset Mortgage Investments Inc., the Master Servicer or the Trustee referred to
below or any of their affiliates or any other person. Neither this Certificate
nor the underlying Mortgage Loans are guaranteed or insured by any governmental
entity or by Structured Asset Mortgage Investments Inc., the Master Servicer or
the Trustee or any of their affiliates or any other person. None of Structured
Asset Mortgage Investments Inc., the Master Servicer or any of their affiliates
will have any obligation with respect to any certificate or other obligation
secured by or payable from payments on the Certificates.

                  This certifies that Cede & Co. is the registered owner of the
Fractional Undivided Interest evidenced hereby in the beneficial ownership
interest of Certificates of the same Class as this Certificate in a trust (the
"Trust Fund") generally consisting of conventional first lien, adjustable rate
mortgage loans secured by one- to four- family residences, units in planned unit
developments and individual condominium units (collectively, the "Mortgage
Loans") sold by Structured Asset

                                       A-2

<PAGE>

Mortgage Investments Inc. ("SAMI"). The Mortgage Loans were sold by EMC Mortgage
Corporation ("EMC") to SAMI. Wells Fargo Bank Minnesota, National Association
("Wells Fargo") will act as master servicer of the Mortgage Loans (the "Master
Servicer," which term includes any successors thereto under the Agreement
referred to below). The Trust Fund was created pursuant to the Pooling and
Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement"), among SAMI, as seller (the "Seller"), Wells Fargo Bank Minnesota,
National Association as master servicer and securities administrator, EMC
Mortgage Corporation and Bank One, National Association, as trustee (the
"Trustee"), a summary of certain of the pertinent provisions of which is set
forth hereafter. To the extent not defined herein, capitalized terms used herein
shall have the meaning ascribed to them in the Agreement. This Certificate is
issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of its
acceptance hereof assents and by which such Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the [Current Principal/Notional] Amount [of each Component] hereof at a per
annum rate equal to the Pass-Through Rate set forth above. The Trustee will
distribute on the 25th day of each month, or, if such 25th day is not a Business
Day, the immediately following Business Day (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
day (or if such last day is not a Business Day, the Business Day immediately
preceding such last day) of the calendar month preceding the month of such
Distribution Date, an amount equal to the product of the Fractional Undivided
Interest evidenced by this Certificate and the amount (of interest and
principal, if any) required to be distributed to the Holders of Certificates of
the same Class as this Certificate. The Assumed Final Distribution Date is the
first anniversary of the Distribution Date immediately following the latest
scheduled maturity date of any Mortgage Loan and is not likely to be the date on
which the [Current Principal/Notional] Amount of this Class of Certificates will
be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice. The
Initial [Current Principal/Notional] Amount of this Certificate is set forth
above. The [Current Principal/Notional] Amount hereof will be reduced to the
extent of distributions allocable to principal hereon and any Realized Losses
allocable hereto.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in fifteen Classes. The Certificates, in the aggregate, evidence the
entire beneficial ownership interest in the Trust Fund formed pursuant to the
Agreement.

                  The Certificateholder, by its acceptance of this Certificate,
agrees that it will look solely to the Trust Fund for payment hereunder and that
the Trustee is not liable to the

                                       A-3

<PAGE>

Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Seller and the rights of the Certificateholders under the
Agreement from time to time by the Seller and the Trustee with the consent of
the Holders of Certificates evidencing Fractional Undivided Interests
aggregating not less than 66-2/3% (or in certain cases, Holders of Certificates
of affected Classes evidencing such percentage of the Fractional Undivided
Interests thereof). Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Fractional Undivided Interest, as requested
by the Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Seller, the Master Servicer, the Trustee and any agent of any of
them may treat the Person in whose name this Certificate is registered as the
owner hereof for all purposes, and none of the Seller, the Master Servicer, the
Trustee or any such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of the (A) final payment or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and (B) disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and the
remittance of all funds due under the Agreement, or (ii) the optional

                                       A-4

<PAGE>

repurchase by the party named in the Agreement of all the Mortgage Loans and
other assets of the Trust Fund in accordance with the terms of the Agreement.
Such optional repurchase may be made only on or after the Distribution Date on
which the aggregate unpaid principal balance of the Mortgage Loans is less than
the percentage of the aggregate Outstanding Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

                                                        A-5

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

         evidencing a fractional undivided interest in the distributions
         allocable to the Class [B-__] Certificates with respect to a Trust Fund
         consisting primarily of a pool of conventional one- to four-family
         adjustable rate mortgage loans sold by STRUCTURED ASSET MORTGAGE
         INVESTMENTS INC.

                  This Certificate is payable solely from the assets of the
Trust Fund, and does not represent an obligation of or interest in Structured
Asset Mortgage Investments Inc., the Master Servicer or the Trustee referred to
below or any of their affiliates or any other person. Neither this Certificate
nor the underlying Mortgage Loans are guaranteed or insured by any governmental
entity or by Structured Asset Mortgage Investments Inc., the Master Servicer or
the Trustee or any of their affiliates or any other person. None of Structured
Asset Mortgage Investments Inc., the Master Servicer or any of their affiliates
will have any obligation with respect to any certificate or other obligation
secured by or payable from payments on the Certificates.

                  This certifies that __________________ is the registered owner
of the Fractional Undivided Interest evidenced hereby in the beneficial
ownership interest of Certificates of the same Class as this Certificate in a
trust (the "Trust Fund") generally consisting of conventional fast lien,
adjustable rate mortgage loans secured by one- to four- family residences, units
in planned unit developments and individual condominium units (collectively, the
"Mortgage Loans") sold by Structured Asset Mortgage Investments Inc. ("SAMI").
The Mortgage Loans were sold by EMC Mortgage Corporation ("EMC") to SAMI. Wells
Fargo Bank Minnesota, National Association ("Wells Fargo") will act as master
servicer of the Mortgage Loans (the "Master Servicer," which

                                      A-2-3

<PAGE>

term includes any successors thereto under the Agreement referred to below). The
Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as
of the Cut-off Date specified above (the "Agreement"), among SAMI, as seller
(the "Seller"), Wells Fargo Bank Minnesota, National Association as master
servicer and securities administrator, EMC Mortgage Corporation and Bank One,
National Association, as trustee (the "Trustee"), a summary of certain of the
pertinent provisions of which is set forth hereafter. To the extent not defined
herein, capitalized terms used herein shall have the meaning ascribed to them in
the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Current Principal Amount hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Trustee will distribute on the 25th day
of each month, or, if such 25th day is not a Business Day, the immediately
following Business Day (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 day (or if such last day is
not a Business Day, the Business Day immediately preceding such last day) of the
calendar month preceding the month of such Distribution Date, an amount equal to
the product of the Fractional Undivided Interest evidenced by this Certificate
and the amount (of interest and principal, if any) required to be distributed to
the Holders of Certificates of the same Class as this Certificate. The Assumed
Final Distribution Date is the first anniversary of the Distribution Date
immediately following the latest scheduled maturity date of any Mortgage Loan
and is not likely to be the date on which the Current Principal Amount of this
Class of Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register or, if such Person so requests
by notifying the Trustee in writing as specified in the Agreement.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose and designated in such notice. The
Initial Current Principal Amount of this Certificate is set forth above. The
Current Principal Amount hereof will be reduced to the extent of distributions
allocable to principal hereon and any Realized Losses allocable hereto.

                  [This Certificate may not be acquired directly or indirectly
by, or on behalf of, an employee benefit plan or other retirement arrangement
which is subject to Title I of the Employee Retirement Income Security Act of
1974, as amended, and/or Section 4975 of the Internal Revenue Code of 1986, as
amended, unless the proposed transfer and/or holding of a Certificate and the
servicing, management and/or operation of the trust and its assets: (i) will not
result in any prohibited transaction which is not covered under an individual or
class prohibited transaction exemption, including, but not limited to,
Prohibited Transaction Exemption ("PTE") 84-14, PTE 91-38, PTE 90-1, PTE 95-60
or PTE 96-23 and (ii) will not give rise to any additional fiduciary obligations

deemed represented by an

owner of a Book-Entry Certificate or a Global Certificate and will be evidenced
by a representation or an Opinion of Counsel to such effect by or on behalf of
an Institutional Accredited Investor.]

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in fifteen Classes. The Certificates, in the aggregate, evidence the
entire beneficial ownership interest in the Trust Fund formed pursuant to the
Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Seller and the rights of the Certificateholders under the
Agreement from time to time by the Seller and the Trustee with the consent of
the Holders of Certificates evidencing Fractional Undivided Interests
aggregating not less than 66-2/3% (or in certain cases, Holders of Certificates
of affected Classes evidencing such percentage of the Fractional Undivided
Interests thereof). Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee.

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Fractional Undivided Interest, as requested
by the Holder surrendering the same.

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

                                      A-2-5

<PAGE>

and any agent of any of them may treat the Person in whose name this Certificate
is registered as the owner hereof for all purposes, and none of the Seller, the
Master Servicer, the Trustee or any such agent shall be affected by notice to
the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of the (A) final payment or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and (B) disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate unpaid principal balance of the Mortgage Loans is less than the
percentage of the aggregate Outstanding Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

below or any of their affiliates or any other person. Neither this Certificate
nor the underlying Mortgage Loans are guaranteed or insured by any governmental
entity or by Structured Asset Mortgage Investments Inc., the Master Servicer or
the Trustee or any of their affiliates or any other person. None of Structured
Asset Mortgage Investments Inc., the Master Servicer or any of their affiliates
will have any obligation with respect to any certificate or other obligation
secured by or payable from payments on the Certificates.

                  This certifies that Bear, Stearns Securities Corp. is the
registered owner of the Fractional Undivided Interest evidenced hereby in the
beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust Fund") generally consisting of conventional
first lien, adjustable rate mortgage loans secured by one- to four- family
residences, units in planned unit developments and individual condominium units
(collectively, the "Mortgage Loans") sold by Structured Asset Mortgage
Investments Inc. ("SAMI"). The Mortgage Loans were sold by EMC Mortgage
Corporation ("EMC") to SAMI. Wells Fargo Bank Minnesota, National Association
("Wells Fargo") will act as master servicer of the Mortgage Loans (the "Master
Servicer," which

                                      A-3-3

<PAGE>

term includes any successors thereto under the Agreement referred to below). The
Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as
of the Cut-off Date specified above (the "Agreement'), among SAMI, as seller
(the "Seller"), Wells Fargo Bank Minnesota, National Association as master
servicer and securities administrator, EMC Mortgage Corporation and Bank One,
National Association, as trustee (the "Trustee"), a summary of certain of the
pertinent provisions of which is set forth hereafter. To the extent not defined
herein, capitalized terms used herein shall have the meaning ascribed to them in
the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Current Principal Amount hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Trustee will distribute on the 25th day
of each month, or, if such 25th day is not a Business Day, the immediately
following Business Day (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 day (or if such last day is
not a Business Day, the Business Day immediately preceding such last day) of the
calendar month preceding the month of such Distribution Date, an amount equal to
the product of the Fractional Undivided Interest evidenced by this Certificate
and the amount (of interest and principal, if any) required to be distributed to
the Holders of Certificates of the same Class as this Certificate. The Assumed
Final Distribution Date is the first anniversary of the Distribution Date
immediately following the latest scheduled maturity date of any Mortgage Loan
and is not likely to be the date on which the Current Principal Amount of this
Class of Certificates will be reduced to zero.

                  Distributions on this Certificate will be made by the Trustee
by check mailed to the address of the Person entitled thereto as such name and
address shall appear on the Certificate Register. Notwithstanding the above, the
final distribution on this Certificate will be made after due notice by the
Trustee of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the office or agency appointed by the Trustee
for that purpose and designated in such notice. The Initial Current Principal
Amount of this Certificate is set forth above. The Current Principal Amount
hereof will be reduced to the extent of distributions allocable to principal
hereon and any Realized Losses allocable hereto.

                  Each Holder of this Certificate will be deemed to have agreed
to be bound by the restrictions set forth in the Agreement to the effect that
(i) each person holding or acquiring any Ownership Interest in this Certificate
must be a United States Person and a Permitted Transferee, (ii) the transfer of
any Ownership Interest in this Certificate will be conditioned upon the delivery
to the Trustee of, among other things, an affidavit to the effect that it is a
United States Person and Permitted Transferee, (iii) any attempted or purported
transfer of any Ownership Interest in this Certificate in violation of such
restrictions will be absolutely null and void and will vest no rights in the
purported transferee, and (iv) if any person other than a United States Person
and a Permitted Transferee acquires any Ownership Interest in this Certificate
in violation of such restrictions, then the Seller will have the right, in its
sole discretion and without notice to the Holder of this

                                      A-3-4

Certificate, to sell this Certificate to a purchaser selected by the Company,
which purchaser may be the Seller, or any affiliate of the Seller, on such terms
and conditions as the Seller may choose.

                  This certificate may not be acquired directly or indirectly
by, or on behalf of, an employee benefit plan or other retirement arrangement
which is subject to title I of the employee retirement income security act of
1974, as amended, and/or section 4975 of the internal revenue code of 1986, as
amended, unless the proposed transfer and/or holding of a certificate and the
servicing, management and/or operation of the trust and its assets: (1) will not
result in or constitute a nonexempt prohibited transaction and is permissible
under applicable law and (2) will not give rise to any additional fiduciary
obligations on the part of the seller, the master servicer or the trustee, which
must be evidenced by an opinion of counsel to such effect by or on behalf of an
institutional accredited investor.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates"),
issued in fifteen Classes. The Certificates, in the aggregate, evidence the
entire beneficial ownership interest in the Trust Fund formed pursuant to the
Agreement.

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

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

                  The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Seller and the rights of the Certificateholders under the
Agreement from time to time by the Seller and the Trustee with the consent of
the Holders of Certificates evidencing Fractional Undivided Interests
aggregating not less than 66-2/3% (or in certain cases, Holders of Certificates
of affected Classes evidencing such percentage of the Fractional Undivided
Interests thereof). Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

                  As provided in the Agreement and subject to certain
limitations therein set forth, the transfer of this Certificate is registrable
with the Trustee upon surrender of this Certificate for registration of transfer
at the offices or agencies maintained by the Trustee for such purposes, duly
endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee.

                                      A-3-5

<PAGE>

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new Certificates evidencing the
same Class and in the same aggregate Fractional Undivided Interest, as requested
by the Holder surrendering the same.

                  No service charge will be made to the Certificateholders for
any such registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Seller, the Master Servicer, the Trustee and any agent of any of
them may treat the Person in whose name this Certificate is registered as the
owner hereof for all purposes, and none of the Seller, the Master Servicer, the
Trustee or any such agent shall be affected by notice to the contrary.

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of the (A) final payment or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and (B) disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate unpaid principal balance of the Mortgage Loans is less than the
percentage of the aggregate Outstanding Principal Balance specified in the
Agreement of the Mortgage Loans at the Cut-off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

                  Unless this Certificate has been countersigned by an
authorized signatory of the Trustee by manual signature, this Certificate shall
not be entitled to any benefit under the Agreement, or be valid for any purpose.

         The undersigned further certifies that it is purchasing a Privately

independently qualify as "Qualified Institutional Buyers" as defined in Rule
144A. It is aware that the sale of the Privately Offered Certificates is being

the transferor may rely on the exemption from the provisions of Section 5 of the
Act provided by Rule 144A. The undersigned understands that the Privately
Offered Certificates may be resold, pledged or transferred only to (i) a person
reasonably believed to be a Qualified Institutional Buyer that purchases for its

is given that the resale, pledge or transfer is being made in reliance in Rule
144A, or (ii) an institutional "accredited investor," as such term is defined
under Rule 501 of the Act in a transaction that otherwise does not constitute a
public offering.

         The undersigned agrees that if at some future time it wishes to dispose
of or exchange any of the Privately Offered Certificates, it will not transfer
or exchange any of the Privately Offered Certificates to a Qualified
Institutional Buyer without first obtaining a Rule 144A and Related Matters
Certificate in the form hereof from the transferee and delivering such
certificate to the addressees hereof. Prior to making any transfer of Privately
Offered Certificates, if the proposed Transferee is an institutional "accredited
investor," the transferor shall obtain from the transferee and deliver to the
addressees hereof an Investment Letter in the form attached to the Pooling and
Servicing Agreement, dated as of March 1, 2002, among Structured Asset Mortgage

employee benefit plan or other retirement arrangement which is subject to Title
I of the Employee Retirement Income Security Act of 1974, as amended, and/or
section 4975 of the Internal Revenue Code of 1986, as amended, or (ii) is
providing a representation or an opinion of counsel to the effect that the
proposed transfer and/or holding of a Privately Offered Certificate and the
servicing, management and/or operation of the Trust and its assets: (I) will not
result in any prohibited transaction which is not covered under a prohibited
transaction exemption, including, but not limited to, Prohibited Transaction
Exemption ("PTE") 84- 14, PTE 91-38, PTE 90-1, PTE 95-60, PTE 96-23 or Section
401(c) of ERISA and the regulations to be promulgated thereunder and (II) will
not give rise to any additional fiduciary duties on the part of the Seller, the
Master Servicer or the Trustee.

                          CUSTODY OF MORTGAGE DOCUMENTS

         Section 2.1 CUSTODIAN TO ACT AS AGENT: ACCEPTANCE OF MORTGAGE Files.
The custodian, as the duly appointed agent of the Trustee for these purposes,

Custodian to the Company for the purpose of recording it in the appropriate
public office for real property records, and the Company, at no expense to the
Custodian, shall promptly cause to be recorded in the appropriate public office
for real property records each such assignment of Mortgage and, upon receipt
thereof from such public office, shall return each such assignment of Mortgage
to the Custodian.

         Section  2.3 REVIEW OF MORTGAGE FILES.

         (a) On or prior to the Closing Date, in accordance with Section 2.02 of
the Pooling and Servicing Agreement, the Custodian shall deliver to the Trustee
an Initial Certification in the form annexed hereto as Exhibit One evidencing
receipt (subject to any exceptions noted therein) of a Mortgage File for each of

         (b) Within 90 days of the Closing Date, the Custodian agrees, for the
benefit of Certificateholders, to review, in accordance with the provisions of

as Exhibit Two to the effect that all such documents have been executed and
received and that such documents relate to the Mortgage Loans identified on the

enforceability, due authorization, recordability, sufficiency or genuineness of
any of the documents included in any Mortgage File or (ii) the collectibility,
insurability, effectiveness or suitability of any of the documents in any
Mortgage File.

<PAGE>

     Upon receipt of written request from the Trustee, the Custodian shall as
soon as practicable supply the Trustee with a list of all of the documents
relating to the Mortgage Loans then contained in the Mortgage Files.

         Section 2.4 NOTIFICATION OF BREACHES OF REPRESENTATIONS AND WARRANTIES.
Upon discovery by the Custodian of a breach of any representation or warranty
made by the Company as set forth in the Pooling and Servicing Agreement with
respect to a Mortgage Loan relating to a Mortgage File, the Custodian shall give
prompt written notice to the Company, the related Servicer and the Trustee.

         Section 2.5 CUSTODIAN TO COOPERATE: RELEASE OF MORTGAGE FILES. Upon
receipt of written notice from the Trustee that the Mortgage Loan Seller has
repurchased a Mortgage Loan pursuant to Article II of the Pooling and Servicing
Agreement, and that the purchase price therefore has been deposited in the
Master Servicer Collection Account or the Distribution Account, then the
Custodian agrees to promptly release to the Mortgage Loan Seller the related
Mortgage File.

         Upon the Custodian's receipt of a request for release (a "Request for
Release") substantially in the form of Exhibit D to the Pooling and Servicing
Agreement signed by a Servicing Officer of the related Servicer stating that it
has received payment in full of a Mortgage Loan or that payment in full will be
escrowed in a manner customary for such purposes, the Custodian agrees promptly
to release to the related Servicer the related Mortgage File. The Company shall
deliver to the Custodian and the Custodian agrees to accept the Mortgage Note
and other documents constituting the Mortgage File with respect to any
Substitute Mortgage Loan.

         From time to time as is appropriate for the servicing or foreclosure of
any Mortgage Loan, including, for this purpose, collection under any Primary
Insurance Policy, the related Servicer shall deliver to the Custodian a Request
for Release signed by a Servicing Officer requesting that possession of all of
the Mortgage File be released to the related Servicer and certifying as to the
reason for such release and that such release will not invalidate any insurance
coverage provided in respect of the Mortgage Loan under any of the Insurance
Policies. Upon receipt of the foregoing, the Custodian shall deliver the
Mortgage File to the related Servicer. The related Servicer shall cause each
Mortgage File or any document therein so released to be returned to the
Custodian when the need therefor by the related Servicer no longer exists,
unless (i) the Mortgage Loan has been liquidated and the Liquidation Proceeds
relating to the Mortgage Loan have been deposited in the Master Servicer
Collection Account or the Distribution Account or (ii) the Mortgage File or such
document has been delivered to an attorney, or to a public trustee or other
public official as required by law, for purposes of initiating or pursuing legal
action or other proceedings for the foreclosure of the Mortgaged Property either
judicially or non-judicially, and the related Servicer has delivered to the
Custodian a certificate of a Servicing Officer certifying as to the name and
address of the Person to which such Mortgage File or such document was delivered
and the purpose or purposes of such delivery.

         At any time that a Servicer is required to deliver to the Custodian a
Request for Release, the Servicer shall deliver two copies of the Request for
Release if delivered in hard copy or the Servicer may furnish such Request for
Release electronically to the Custodian, in which event the Servicing Officer
transmitting the same shall be deemed to have signed the Request for Release. In
connection with any Request for Release of a Mortgage File because of a
repurchase of a Mortgage Loan, such

                                       G-3

<PAGE>

Request for Release shall be accompanied by an assignment of Mortgage, without
recourse, from the Trustee to the Mortgage Loan Seller and the related Mortgage
Note shall be endorsed without recourse by the Trustee and be returned to the
Mortgage Loan Seller. In connection with any Request for Release of a Mortgage
File because of the payment in full of a Mortgage Loan, such Request for Release
shall be accompanied by a certificate of satisfaction or other similar
instrument to be executed by or on behalf of the Trustee and returned to the
related Servicer.

         Section 2.6 ASSUMPTION AGREEMENTS. In the event that any assumption
agreement or substitution of liability agreement is entered into with respect to
any Mortgage Loan subject to this Agreement in accordance with the terms and
provisions of the Pooling and Servicing Agreement, the Master Servicer, to the
extent provided in the related Servicing Agreement, shall cause the related
Servicer to notify the Custodian that such assumption or substitution agreement
has been completed by forwarding to the Custodian the original of such
assumption or substitution agreement, which shall be added to the related
Mortgage File and, for all purposes, shall be considered a part of such Mortgage
File to the same extent as all other documents and instruments constituting
parts thereof.

                                   ARTICLE 3.
                            CONCERNING THE CUSTODIAN

         Section 3.1 CUSTODIAN A BAILEE AND AGENT OF THE TRUSTEE. With respect
to each Mortgage Note, Mortgage and other documents constituting each Mortgage
File which are delivered to the Custodian, the Custodian is exclusively the
bailee and agent of the Trustee and has no instructions to hold any Mortgage
Note or Mortgage for the benefit of any person other than the Trustee and the
Certificateholders and undertakes to perform such duties and only such duties as
are specifically set forth in this Agreement. Except upon compliance with the
provisions of Section 2.5 of this Agreement, no Mortgage Note, Mortgage or
Mortgage File shall be delivered by the Custodian to the Company, the Servicers
or the Master Servicer or otherwise released from the possession of the
Custodian.

         Section 3.2 RESERVED.

         Section 3.3 CUSTODIAN MAY OWN CERTIFICATES. The Custodian in its
individual or any other capacity may become the owner or pledgee of Certificates
with the same rights it would have if it were not Custodian.

         Section 3.4 MASTER SERVICER TO PAY CUSTODIAN'S FEES AND EXPENSES. The
Master Servicer covenants and agrees to pay to the Custodian from time to time,
and the Custodian shall be entitled to, reasonable compensation for all services
rendered by it in the exercise and performance of any of the powers and duties
hereunder of the Custodian, and the Master Servicer will pay or reimburse the
Custodian upon its request for all reasonable expenses, disbursements and
advances incurred or made by the Custodian in accordance with any of the
provisions of this Agreement (including the reasonable compensation and the
expenses and disbursements of its counsel and of all persons not regularly in
its employ), except any such expense, disbursement or advance as may arise from
its negligence or bad faith or to the extent that such cost or expense is
indemnified by the Company pursuant to the Pooling and Servicing Agreement.

         Section 3.5 CUSTODIAN MAY RESIGN TRUSTEE MAY REMOVE CUSTODIAN. The
Custodian may resign from the obligations and duties hereby imposed upon it as
such obligations and duties relate to its acting as Custodian of the Mortgage

successor Custodian shall be a depository institution subject to supervision or
examination by federal or state authority shall be able to satisfy the other
requirements contained in Section 3.7 and shall be unaffiliated with the
Servicer or the Company.

         Any resignation or removal of the Custodian and appointment of a
successor Custodian pursuant to any of the provisions of this Section 3.5 shall
become effective upon acceptance of appointment by the successor Custodian. The
Trustee shall give prompt notice to the Company and the Master Servicer of the
appointment of any successor Custodian. No successor Custodian shall be
appointed by the Trustee without the prior approval of the Company and the
Master Servicer.

         Section 3.6 MERGER OR CONSOLIDATION OF CUSTODIAN. Any Person into which
the Custodian may be merged or converted or with which it may be consolidated,
or any Person resulting from any merger, conversion or consolidation to which
the Custodian shall be a party, or any Person succeeding to the business of the
Custodian, shall be the successor of the Custodian hereunder, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto, anything herein to the contrary notwithstanding.

         Section 3.7 REPRESENTATIONS OF THE CUSTODIAN. The Custodian hereby
represents that it is a depository institution subject to supervision or
examination by a federal or state authority, has a combined capital and surplus
of at least $15,000,000 and is qualified to do business in the jurisdictions in

applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated, and in any other appropriate public recording office or elsewhere,

provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement or of the Certificates
