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

         Pooling and Servicing Agreement dated as of April 1, 2003, among
Structured Asset Mortgage Investments Inc., a Delaware corporation, as seller
(the "Seller"), JPMorgan Chase Bank, a New York banking corporation, 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 sole class of "residual interests" in such REMIC.

         The Trustee on behalf of the Trust shall make an election for the REMIC
I Regular Interests, which constitute 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 $632,190,222.63. 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:

                          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
Master Servicer Collection Account, (iii) such assets relating to the Mortgage
Loans as from time to time may be held by the Servicers in Protected Accounts,
the Master Servicer in the Master Servicer Collection Account and the Trustee in

respect to the Servicing Agreements as assigned to the Trustee on behalf of the
Certificateholders by the Assignment Agreements, (viii) the rights under the Cap

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

if clause (x) in the proviso below applies, shall be in recordable form),

                   (iii) unless the Mortgage Loan is a MOM Loan, a certified

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

                                      -34-

                  (iii) The related Cooperative Stock Certificate, representing
the related Cooperative Stock pledged with respect to such Cooperative Loan,
together with an undated stock power (or other similar instrument) executed in
blank;

                  (iv) The original recognition agreement by the Cooperative of
the interests of the mortgagee with respect to the related Cooperative Loan;

                  (v) The Security Agreement;

                  (vi) Copies of the original UCC-1 financing statement, and any
continuation statements, filed by the originator of such Cooperative Loan as
secured party, each with evidence of recording thereof, evidencing the interest
of the originator under the Security Agreement and the Assignment of Proprietary

interest referenced in clause (vi) above showing an unbroken chain of title from

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 of the Mortgage Loans 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 (a) 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 or (b) MERS is identified on
the Mortgage or on a properly recorded assignment of the Mortgage as the
mortgagee of record solely as nominee for Seller and its successor and assigns;
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.
         (c) The Seller hereby assigns to the Trustee its security interest in
and to any Additional Collateral, its right to receive amounts due or to become

         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 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 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 Trustee an Interim Certification. 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

                                      -37-
<PAGE>

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 and the Trustee a Final Certification. 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 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 (a
"Material Defect"), 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 subsections (I)(b)(iv), (v) and (vii) of Section 2.01 and
subsection (II)(ix) 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 within 90 days from the date of notice from the
Trustee or the Custodian, as its agent, of the Material 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
provide a Substitute Mortgage Loan (if within two years of the Closing Date) or
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, repurchase or
substitution 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.

         (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,
representation or warranty, 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 the

                                      -38-
<PAGE>

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 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 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, 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, representation or
warranty 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 Securities
Administrator shall amend the Mortgage Loan Schedule to reflect such repurchase
and shall promptly notify the Trustee and the Rating Agencies of such amendment.
Enforcement of the obligation of the Mortgage Loan Seller to purchase (or

                                      -39-
<PAGE>

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, representation or warranty 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

                                      -40-
<PAGE>

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 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

         do business in each jurisdiction where such qualification is necessary,
         except where the failure so to qualify would not reasonably be expected

         this Agreement, nor the consummation of the transactions herein

         affecting the enforcement of the rights of creditors generally);

                  (vi) there are no actions, suits or proceedings pending or, to

                                   ARTICLE III

                 Administration and Servicing of Mortgage Loans

         Section 3.01 MASTER SERVICER. (a) 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.

         Notwithstanding anything in this Agreement to the contrary, with
respect to any Mortgage Loan secured by any Additional Collateral, the Master
Servicer shall have no duty of obligation to supervise, monitor or oversee the
activities of Cendant (or any successor thereto) under any Cendant Servicing
Agreement with respect to any Additional Collateral (unless the Master Servicer
shall have assumed the obligations of Cendant (or any successor thereto) as
successor Servicer under the applicable Cendant Servicing Agreement pursuant to
Section 3.03 of this Agreement, in which event, as successor Servicer, it will
service and administer the Additional Collateral in accordance with the
provisions of such Cendant Servicing Agreement.

         (b) 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.

         (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

                                      -43-
<PAGE>

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 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

                                      -44-
<PAGE>

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 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.

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

         The Master Servicer shall use its best efforts to cause each Servicer
of a Cooperative Loan to timely file continuation statements with regard to each
financing statement and assignment relating to Cooperative Loans as to which the
related Cooperative Apartment is located outside of the State of New York.

         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

                                      -45-
<PAGE>

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 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 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

                                      -46-
<PAGE>

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.

         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 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.

         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

                                      -47-
<PAGE>

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 each 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
such Servicer under this Agreement or the applicable Servicing Agreement.

         Section 3.09 STANDARD HAZARD INSURANCE AND FLOOD INSURANCE POLICIES.

         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.

         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.

         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 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.

         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 Master Servicer Collection Account and the
Distribution 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 deposited in the Protected Account. The Master Servicer will be
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 required to be remitted to the Distribution Account (such
amounts together with the amounts specified in the first sentence of this
Section 3.14, the "Master Servicing Compensation"). 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.

         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.

         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.

         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,

                                      -50-
<PAGE>

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 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.

         The Master Servicer shall deliver to the Trustee and the Rating
Agencies on or before March 1 of each year, commencing on March 1, 2004, an
Officer's Certificate, certifying that with respect to the period ending
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
Agreement in all material respects throughout such year, or, if there has been 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.

         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 March 1 of each year, commencing on March 1, 2004 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

                                      -51-
<PAGE>

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 make available a copy of the monthly
statement to the Certificateholders for such Distribution Date as an exhibit
thereto. Prior to January 30 in each year, 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 (i) March 15, 2004 and (ii) unless and until a Form 15 Suspension Notice
shall have been filed, prior to March 15 of each year thereafter, the Master
Servicer shall provide the Securities Administrator with a Master Servicer
Certification, together with a copy of the annual independent accountant's
servicing report and annual statement of compliance of each Servicer, in each
case, required to be delivered pursuant to the related Servicing Agreement, and,
if applicable, the annual independent accountant's servicing report and annual
statement of compliance to be delivered by the Master Servicer pursuant to
Sections 3.16 and 3.17. Prior to (i) March 31, 2004, or such earlier filing date
as may be required by the Commission, and (ii) unless and until a Form 15
Suspension Notice shall have been filed, March 31 of each year thereafter, or
such earlier filing date as may be required by the Commission, the Securities
Administrator shall file a Form 10-K, in substance conforming to industry
standards, with respect to the Trust. Such Form 10-K shall include the Master
Servicer Certification and other documentation provided by the Master Servicer
pursuant to the second preceding sentence. 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 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"). 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 Seller shall inform the Trustee in writing of any
Uniform Commercial Code financing statements that were filed on the Closing Date
in connection with the Trust with stamped recorded copies of such financing
statements to be delivered to the Trustee promptly upon receipt by the Seller.
The Trustee agrees to monitor and notify the Seller if any continuation
statements for such Uniform Commercial Code financing statements need to be
filed. If directed by the Seller in writing, the Trustee will file any such
continuation statements solely at the expense of the Seller. 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 to EMC at the request of EMC
without recourse, representation or warranty and EMC shall succeed to all of 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.

Servicer Collection 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.

demand of a Servicer or the Securities Administrator, make or cause to be made
such withdrawals or transfers from the Master Servicer Collection Account as the
Master Servicer has designated for such transfer or withdrawal pursuant to this

         On an ongoing basis, the Master Servicer shall withdraw from the Master
Servicer Collection Account (i) any expenses recoverable by the Trustee, the

         (b) All amounts deposited to the Distribution Account shall be held by

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 or
the Master Servicer (whether made directly, or indirectly through a liquidator
or receiver of the Trustee or the Master Servicer). The Distribution Account
shall be an Eligible Account. The amount at any time credited to the
Distribution Account shall be (i) held in cash or fully insured by the FDIC to
the maximum coverage provided thereby or (ii) 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 or benefit from funds uninvested therein from time

estate of the Trustee) as provided by 12 U.S.C. ss. 92a(e), and applicable

         Section 4.06 RESERVE FUND. (a) On or before the Closing Date, the
Trustee shall establish a Reserve Fund on behalf of the Class I-A, Class II-A
and Class M Certificateholders. The Reserve Fund must be an Eligible Account.
The Reserve Fund shall be entitled "Reserve Fund, JPMorgan Chase Bank as Trustee
for the benefit of holders of Structured Asset Mortgage Investments Inc., Bear
Stearns ALT-A Trust, Mortgage Pass-Through Certificates, Series 2003-1". The
Trustee shall demand payment of all money payable by Bear Stearns Financial
Products Inc. (the "Counterparty") under the Cap Contracts. The Trustee shall
deposit in the Reserve Fund all payments received from the Counterparty pursuant
to the Cap Contracts. On each Distribution Date, the Trustee shall remit amounts
received from the Counterparty to the Class I-A and Class M Certificateholders
in the manner provided in Section 6.01(b) hereof. In addition, on each

<PAGE>

Class II-A and Class M Certificates, an amount equal to the amount of any Basis
Risk Shortfall Carry-Forward Amount on such Classes of Certificates in the
manner provided in Section 6.01(a).

         (b) The Reserve Fund is an "outside reserve fund" within the meaning of
Treasury Regulation ss.1.860G-2(h) and shall be an asset of the Trust Fund but

beneficial owner of the Reserve Fund, subject to the power of the Trustee to
transfer amounts under Section 6.01(b). Amounts in the Reserve Fund shall, at
the direction of the Class B-IO Certificateholder, be held either uninvested in
a trust or deposit account of the Trustee with no liability for interest or
other compensation thereon or invested in Permitted Investments that mature no
later than the Business Day prior to the next succeeding Distribution Date. The
Trustee shall distribute all net income and gain from such investments in the
Reserve Fund to the Class B-IO Certificateholder, not as a distribution in
respect of any interest in any REMIC, on each Distribution Date. All amounts
earned on amounts on deposit in the Reserve Fund shall be taxable to the Class
B-IO Certificateholder. Any losses on such investments shall be deposited in the
Reserve Fund by the Class B-IO Certificateholder out of its own funds
immediately as realized.

         Section 4.07 CLASS XP RESERVE ACCOUNT. (a) The Master Servicer shall

Closing Date, the Depositor shall deposit $100 into the Class XP Reserve
Account. Funds on deposit in the Class XP Reserve Account shall be held in trust
by the Master Servicer for the holder of the Class XP Certificate.

         (b) The amount on deposit in the Class XP Reserve Account shall be held
uninvested. On the earlier of (x) the Business Day prior to the Distribution
Date on which all the assets of the Trust Fund are repurchased as described in
Section 10.01(a) and (y) the Business Day prior to the Distribution Date
immediately following the Prepayment Period during which the last Prepayment
Charge on the Mortgage Loans is payable by the related Mortgagor which
Prepayment Period is the month of April 2008, the Master Servicer shall withdraw
the amount on deposit in the Class XP Reserve Account and remit such amount to
the Trustee and provide instruction to the Trustee to pay such amount to the
Class XP Certificate in reduction of the Certificate Principal Balance thereof.

                                  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 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) [RESERVED].

                  (ii) 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 "residual interest" in REMIC I. On each
         Distribution Date, the Trustee shall cause in the following order of
         priority, the following amounts to be distributed by REMIC I to REMIC
         II on account of the REMIC I Regular Interests or withdrawn from the
         Distribution Account and distributed to the holders of the Class R-I
         Certificates, as the case may be:

                  (1) first, from Interest Funds,

                  (A) to Holders of REMIC I Regular Interest LT-AA, REMIC I
Regular Interest LT-A1, REMIC I Regular Interest LT-A2, REMIC I Regular Interest
LT-M1, REMIC I Regular Interest LT-ZZ and REMIC I Regular Interest LT-XP, pro
rata, in an amount equal to (A) the related Uncertificated Accrued Interest for
such Distribution Date, plus (B) any amounts in respect thereof remaining unpaid
from previous Distribution Dates. Amounts payable as Uncertificated Accrued
Interest in respect of REMIC I Regular Interest LT-ZZ on a Distribution Date
shall be reduced when the REMIC I Overcollateralized Amount for such
Distribution Date is less than the REMIC I Overcollateralization Target Amount,
by the lesser of (x) the amount of such difference and (y) the Maximum
Uncertificated Accrued Interest Deferral Amount for such Distribution Date, and
such amount will be payable to the Holders of REMIC I Regular Interest LT-A1,
REMIC I Regular Interest LT-A2 and REMIC I Regular Interest LT-M1 in the same
proportion as the Extra Principal Distribution Amount is allocated to the
Corresponding Certificates for such Distribution Date;

                           (B) to Holders of REMIC I Regular Interest LT-1SUB,
REMIC I Regular Interest LT-1GRP, REMIC I Regular Interest LT-2SUB, REMIC I
Regular Interest LT-2GRP and REMIC I Regular Interest LT-XX, pro rata, in an
amount equal to (A) the Uncertificated Accrued Interest for such Distribution
Date, plus (B) any amounts in respect thereof remaining unpaid from previous
Distribution Dates

                  (2) second, from the REMIC I Marker Allocation Percentage of
         Principal Funds to the Holders of REMIC I Regular Interests, allocated
         as follows:

                           (A) to the Holders of REMIC I Regular Interest LT-AA,
         98.00% of such Principal Funds, until the Uncertificated Balance of
         such REMIC I Regular Interest is reduced to zero;

                           (B) to the Holders of REMIC I Regular Interest LT-A1,
         REMIC I Regular Interest LT-A2 and REMIC I Regular Interest LT-M1,
         1.00% of such Principal Funds, in the same proportion as principal
         payments are allocated to the Corresponding Certificates, until the
         Uncertificated Principal Balances of such REMIC I Regular Interests are
         reduced to zero;

                           (C) to the Holders of REMIC I Regular Interest LT-ZZ,
         1.00% of such Principal Funds, until the Uncertificated Principal
         Balance of such REMIC I Regular Interest is reduced to zero; and

                                      -62-
<PAGE>

                           (D) any remaining amount to the Holders of the Class
         R-I Certificates;

         provided that, REMIC I Regular Interest LT-XP shall not be reduced
         until the Distribution Date immediately following the expiration of the
         latest Prepayment Charge as identified on the Prepayment Charge
         Schedule or any Distribution Date thereafter, at which point such
         amount shall be withdrawn from the Class XP Reserve Account and
         distributed to REMIC I Regular Interest LT-XP, until $100 has been
         distributed pursuant to this clause.

                  (3) third, from the REMIC I Sub WAC Allocation Percentage of
Principal Funds to the Holders of REMIC I Regular Interests, allocated as
follows:

                           Distributions of principal shall be deemed to be made
to REMIC I Regular Interests LT-1SUB, LT-1GRP, LT-2SUB, LT-2GRP and LT-XX,
first, so as to keep the Uncertificated Principal Balance of each REMIC I
Regular Interest ending with the designation "GRP" equal to 0.01% of the
aggregate Stated Principal Balance of the Mortgage Loans in the related Group;
second, 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 Stated Principal Balance of
the Mortgage Loans in the related Group over (y) the Certificate Principal
Balance of the Class A 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 LT-XX.

                  (4) For purposes of calculating the amount of Uncertificated
         Accrued Interest for the Uncertificated REMIC I Regular Interests for
         any Distribution Date:

                           (A) the aggregate amount of the REMIC I Marker
Allocation Percentage of any Prepayment Interest Shortfalls and the REMIC I
Marker Allocation Percentage of shortfalls resulting from application of the
Relief Act incurred in respect of the Mortgage Loans for any Distribution Date
shall be allocated (i) first, to Uncertificated Accrued Interest payable to
REMIC I Regular Interest LT-AA and REMIC I Regular Interest LT-ZZ up to an
aggregate amount equal to the REMIC I Interest Loss Allocation Amount, 98% and
2%, respectively, and thereafter among REMIC I Regular Interest LT-AA, REMIC I
Regular Interest LT-A1, REMIC I Regular Interest LT-A2, REMIC I Regular Interest
LT-M1 and REMIC I Regular Interest LT-ZZ, pro rata based on, and to the extent
of, one month's interest at the then applicable respective Uncertificated REMIC
I Pass-Through Rate on the respective Uncertificated Principal Balance of each
such Uncertificated REMIC I Regular Interest; and

                           (B) the aggregate amount of the REMIC I Sub WAC
Allocation Percentage of any Prepayment Interest Shortfalls and the REMIC I Sub
WAC Allocation Percentage of shortfalls resulting from application of the Relief
Act incurred in respect of the Mortgage Loans for any Distribution Date shall be
allocated first, to Uncertificated Accrued Interest payable to REMIC I Regular
Interest LT-1SUB, REMIC I Regular Interest LT-1GRP, REMIC I Regular Interest
LT-2SUB, REMIC I Regular Interest LT-2GRP and REMIC I Regular Interest LT-XX,
pro rata based on, and to the extent of, one month's interest at the then
applicable respective

                                      -63-
<PAGE>

Uncertificated REMIC I Pass-Through Rate on the respective Uncertificated
Principal Balance of each such REMIC I Regular Interest.

                  (5) (A) The REMIC I Marker Allocation Percentage of all
Realized Losses on the Mortgage Loans shall be deemed to have been allocated in
the specified percentages, as follows: first, to Uncertificated Accrued Interest
payable to the REMIC I Regular Interest LT-AA and REMIC I Regular Interest LT-ZZ
up to an aggregate amount equal to the REMIC I Interest Loss Allocation Amount,
98% and 2%, respectively; second, to the Uncertificated Principal Balances of
REMIC I Regular Interest LT-AA and REMIC I Regular Interest LT-ZZ up to an
aggregate amount equal to the REMIC I Principal Loss Allocation Amount, 98% and
2%, respectively; and third, to the Uncertificated Principal Balances of REMIC I
Regular Interest LT-AA, REMIC I Regular Interest LT-M1 and REMIC I Regular
Interest LT-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal
Balance of REMIC I Regular Interest LT-M1 has been reduced to zero; and

                           (B) The REMIC I Sub WAC Allocation Percentage of all
Realized Losses on the Mortgage Loans shall be deemed to have been allocated in
the specified percentages, as follows: first, so as to keep the Uncertificated
Principal Balance of each REMIC I Regular Interest ending with the designation
"GRP" equal to 0.01% of the aggregate Stated Principal Balance of the Mortgage
Loans in the related Loan Group; second, 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 Stated Principal Balance of the Mortgage Loans in the related Loan
Group over (y) the Certificate Principal Balance of the Senior Certificate in
the related Loan 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, any remaining Realized Losses shall be
allocated to REMIC I Regular Interest LT-XX.

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

designated as the "latest possible maturity date" for the REMIC I Regular

shall accrue interest during the related Interest Accrual Period. With respect
to each Distribution Date and (i) each such

                                      -65-
<PAGE>

Class of Certificates (other than the Class XP Certificates and Class B-IO
Certificates), interest shall be calculated, on the basis of a 360-day year and
the actual number of days elapsed in the related Interest Accrual Period, based
upon the respective Pass-Through Rate set forth, or determined as provided,
above and the Certificate Principal Balance of such Class applicable to such
Distribution Date. With respect to each Distribution Date and the Class B-IO
Certificates, interest shall be calculated, on the basis of a 360-day year
consisting of twelve 30-day months, based upon the respective Pass-Through Rate
set forth, or determined as provided, above and the Certificate Principal
Balance of such Class applicable to such Distribution Date.

         (f) The Certificates shall be substantially in the forms set forth in
Exhibits A-1, A-2, A-3, A-4 and A-5. 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 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 Certificate Principal Balance 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
Certificate Principal Balance of such Class on the Closing Date. The Residual
Certificates shall each be issued in certificated fully-registered form. 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 Certificate Principal Balance 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 Certificate Principal Balance 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
Certificate Principal Balance of each such respective Class on the Closing Date.
The Certificates referred to in clause (i) and if at

                                      -66-
<PAGE>

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 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:

         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

<PAGE>

                  (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 addressed to the Trustee 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 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

                                      -70-
<PAGE>

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 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

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

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 the Corporate Trust Office, sign, countersign and
deliver at the 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 the Corporate Trust Office; 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.

         (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

                                      -72-
<PAGE>

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

                                      -73-
<PAGE>

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.

         (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 (a "Plan") which is subject to Title I of ERISA and/or
Section 4975 of the Code or by a person using assets of a Plan, unless the
proposed transferee provides either (i) the Trustee with an Opinion of Counsel
for the benefit of the Trustee, the Master Servicer and the Securities
Administrator and on which they may rely which is the satisfactory to the
Trustee, 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 XP Certificates and
Class B-IO Certificates, a representation or certification to the Trustee (upon
which the Trustee is authorized to rely) to the effect that the proposed
transfer and 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 ("PTCE") 84-14 (Class
Exemption for Plan Asset Transactions Determined by Independent Qualified
Professional Asset Managers); PTCE 91-38 (Class Exemption for Certain
Transactions Involving Bank Collective Investment Funds); PTCE 90-1 (Class
Exemption for Certain Transactions Involving Insurance Company Pooled Separate
Accounts), PTCE 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 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 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 holding of an interest in
such Certificate to that Person and the subsequent servicing, management and
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, PTCE 84-14, PTCE 91-38,
PTCE 90-1, PTCE 95-60 or PTCE 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) Each beneficial owner of a Class M Certificate or any interest
therein shall be deemed to have represented, by virtue of its acquisition or
holding of that certificate or interest therein, that either (i) it is not a
Plan or investing with "Plan Assets", (ii) (1) it is an insurance company, (2)
the source of funds used to acquire or hold the certificate or interest therein
is an "insurance company general account," as such term is defined in Prohibited
Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in Sections I
and III of PTCE 95-60 have been satisfied.

         (d) 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

                                      -75-
<PAGE>

to the Global Certificates. Any attempted or purported transfer of any
Certificate in violation of the provisions of Subsections (a), (b) or (c) 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.

         Extra Principal Distribution Amount for such Distribution Date:

                  1. To the Class I-A Certificates and Class II-A Certificates,
         the Principal Distribution Amount, pro rata, based on the Principal

         otherwise allocable to such Class A Certificates will be allocated to
         the remaining Class of Class A Certificates; and

Certificates, the Class B-IO Distribution Amount; and

         SEVENTH, any remaining amounts to the Residual Certificates.

         (c) On each Distribution Date, all amounts representing Prepayment
Charges in respect of the Prepayment Charge Loans received during the related
Prepayment Period will be withdrawn from the Distribution Account and
distributed by the Trustee to the Class XP Certificates and shall not be
available for distribution to the holders of any other Class of Certificates.
The payment of such Prepayment Charges shall not reduce the Certificate
Principal Balance of the Class XP Certificates. In addition, as provided in
Section 4.07 hereof, on the Distribution Date immediately following the
Prepayment Period in which the last Prepayment Charge is collectible on the
Prepayment Charge Loans which Prepayment Period is the month of April 2008, the
Trustee shall distribute the amount on deposit in the Class XP Reserve Account

thereof until the Certificate Principal Balance thereof is reduced to zero.

         (d) 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. 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. Any Realized Losses with respect to the Mortgage Loans shall be
applied on each Distribution Date after the distributions provided for in
Section 6.01, in reduction of the Certificate Principal Balance of the Class M
Certificates as provided in the definition of Applied Realized Loss Amount.

         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.

         Section 6.04 STATEMENTS TO CERTIFICATEHOLDERS. (a) Concurrently with
each distribution to Certificateholders, the Securities Administrator shall make

Fractional Undivided Interest representing an initial Certificate Principal
Balance of $1,000, in the case of the Interest Only Certificates, a Notional
Amount of $1,000:

                  (i) the Certificate Principal Balance or Notional Amount of
         each Class of Certificates immediately prior to such Distribution Date;

                  (ii) the amount of the distribution allocable to principal on
         each applicable Class of Certificates;

                  (iii) the aggregate amount of interest accrued at the related
         Pass-Through Rate with respect to each Class during the related

The Securities Administrator may conclusively rely on such information and shall
not be required to confirm, verify or recalculate any such information.

         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 Securities Administrator's 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.

         To the extent timely received from the Securities Administrator, the
Trustee will also make monthly statements available each month to
Certificateholders via the Trustee's internet website. The Trustee's internet
website will initially be located at www.jpmorgan.com/absmbs. Assistance in
using the Trustee's website service can be obtained by calling the Trustee's
customer service desk at (877) 722-1095.

         (b) By April 30 of each year beginning in 2004, the Trustee will

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 a Nonrecoverable Advance. 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 the Master
Servicer deems an advance to be a Nonrecoverable Advance, on the Distribution
Account Deposit Date, the Master Servicer shall present an Officer's Certificate

                                      -83-
<PAGE>

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 a Nonrecoverable Advance.

         Section 6.06 COMPENSATING INTEREST PAYMENTS. The Master Servicer shall
deposit in the Master Servicer Collection Account not later than each
Distribution Account Deposit Date an amount equal to the lesser of (i) the sum
of the aggregate amounts required to be paid by the Servicers under the
Servicing Agreements with respect to subclauses (a) and (b) of the definition of
Interest Shortfall with respect to the Mortgage Loans for the related
Distribution Date, and not so paid by the related Servicers and (ii) the Master
Servicing Compensation for such Distribution Date (such amount, the
"Compensating Interest Payment"). The Master Servicer shall not be entitled to
any reimbursement of any Compensating Interest Payment.

                               The Master Servicer

         Section 7.01 LIABILITIES OF THE MASTER SERVICER. The Master Servicer
shall be liable in accordance herewith only to the extent of the obligations
specifically imposed upon and undertaken by it herein.

         Section 7.02 MERGER OR CONSOLIDATION OF THE MASTER SERVICER.

         The Master Servicer will keep in full force and effect its existence,
rights and franchises as a corporation under the laws of the state of its
incorporation, and will obtain and preserve its qualification to do business as
a foreign corporation in each jurisdiction in which such qualification is or
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, the Servicing Agreements, the
Assignment Agreements or the Certificates or the powers of attorney delivered by
the Trustee hereunder (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. The Trustee's failure to deliver
any such notice shall not affect the Trustee's right to indemnification
hereunder, except to the extent the Master Servicer is materially prejudiced by
such failure to give notice. 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 covered by the
Master Servicer's indemnification pursuant to Subsection (a) above.

<PAGE>

         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 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
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

                                      -86-
<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. Notwithstanding the foregoing, the compensation payable to a
successor master servicer may not exceed the compensation which the Master
Servicer would have been entitled to retain if the Master Servicer had continued
to act as Master Servicer hereunder.

         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 addressed to the Trustee,

                                      -87-
<PAGE>

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 termination
fee equal to 0.25% of the aggregate Stated 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 cause to be deposited in the
         Distribution Account any amount so required to be deposited pursuant to
         this Agreement (other than a Monthly Advance), 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;

                  (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;
         or

                                      -89-
<PAGE>

                  (vi) The Master Servicer fails to deposit, or cause to be
         deposited, in the Distribution Account any Monthly Advance (other than
         a Nonrecoverable Advance) by 5:00 p.m. New York City time on the
         Distribution Account Deposit Date.

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.

         Notwithstanding the foregoing, if an Event of Default described in
clause (vi) of this Section 8.01 shall occur, the Trustee shall, by notice in
writing to the Master Servicer, which may be delivered by telecopy, immediately
terminate all of the rights and obligations of the Master Servicer thereafter
arising under this Agreement, but without prejudice to any rights it may have as
a Certificateholder or to reimbursement of Monthly Advances and other advances
of its own funds, and the Trustee shall act as provided in Section 8.02 to carry
out the duties of the Master Servicer, including the obligation to make any
Monthly Advance the nonpayment of which was an Event of Default described in
clause (vi) of this Section 8.01. Any such action taken by the Trustee must be
prior to the distribution on the relevant Distribution Date.

         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 compensation 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 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, the
compensation shall not be in excess of that to which the Master Servicer would
have been entitled to if the Master Servicer had continued to act hereunder, 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 actually known to a Responsible Officer of the Trustee, unless such
Event of Default shall have been cured, notice of each such Event of Default.
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, which default may only be waived by Holders of Certificates
evidencing Fractional Undivided Interests aggregating 100% of the Trust Fund.
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 hereunder; 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
solely on 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

                                      -93-
<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, the Seller, the
         Master Servicer, 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.

                  (viii) 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 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.

                                      -94-
<PAGE>

         (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.

         (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 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,

                                      -95-
<PAGE>

         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 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 the Mortgage Loan Purchase
         Agreement or this 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 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
3.20.

         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.

         Section 9.05 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 between the Trustee and
the Master Servicer. In addition, the Trustee and the Securities Administrator
will be entitled to recover from the Master Servicer Collection Account pursuant
to Section 4.03 all reasonable out-of-pocket expenses, disbursements and
advances and the expenses of the Trustee and 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

                                      -97-
<PAGE>

Certificateholders. If funds in the Master Servicer Collection Account are
insufficient therefor, the Trustee and the Securities Administrator shall
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 9.06 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
Moody's with respect to any outstanding long-term unsecured unsubordinated debt,
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
effect specified in Section 9.08.

         Section 9.07 INSURANCE. The Trustee and the Securities Administrator,
at their own expense, shall at all times maintain and keep in full force and
effect: (i) fidelity insurance, (ii) theft of documents insurance and (iii)
forgery insurance (which may be collectively satisfied by a "Financial
Institution Bond" and/or a "Bankers' Blanket Bond"). All such insurance shall be
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 9.08 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 and the Master 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.

                                      -98-
<PAGE>

         (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
the Trustee or the Securities Administrator shall become incapable of acting, or
shall be adjudged a bankrupt or insolvent, or a receiver of the Trustee or the
Securities Administrator, as applicable, or of its property shall be appointed,
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
Administrator, as applicable, by written instrument, in triplicate, one copy of
which instrument shall be delivered to each of the Trustee or Securities
Administrator, as applicable, so removed, the successor Trustee or Securities
Administrator, as applicable.

         (c) The Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than 51% of the Trust Fund may at any time remove
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,
the Securities Administrator (if the Trustee is removed), the Trustee (if the
Securities Administrator is removed), and the Trustee or Securities
Administrator so removed and the successor so appointed. In the event that the
Trustee or Securities Administrator is removed by the Holders of Certificates in
accordance with this Section 9.08(c), the Holders of such Certificates shall be
responsible for paying any compensation payable to a successor Trustee or
successor Securities Administrator, in excess of the amount paid to the
predecessor Trustee or predecessor Securities Administrator, as applicable.

         (d) No resignation or removal of the Trustee or the Securities
Administrator and appointment of a successor Trustee or 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
and deliver such instruments and do such other things as may reasonably be
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.

         (b) No successor Trustee or Securities Administrator shall accept
appointment as provided in this Section 9.09 unless at the time of such
acceptance such successor Trustee or Securities Administrator shall be eligible
under the provisions of Section 9.06.

         (c) Upon acceptance of appointment by a successor Trustee or Securities
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 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 co- trustee 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

                                     -100-
<PAGE>

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.

         (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 with
respect to Loan Group 1 and 60% CPR with respect to Loan Group 2). 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

                                     -101-
<PAGE>

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 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

                                     -102-
<PAGE>

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 EMC 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 EMC or its
         designee of all Mortgage Loans and all related REO Property remaining
         in the Trust at a price (the "Termination Purchase Price") equal to the
         sum of (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, (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 EMC, (c) unreimbursed out-of pocket costs
         of the Master Servicer, including unreimbursed servicing advances and
         the principal portion of any unreimbursed Monthly Advances, made on the
         Mortgage Loans prior to the exercise of such repurchase right and (d)
         any unreimbursed costs and expenses of the Trustee and the Securities
         Administrator payable pursuant to Section 9.05; 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.

                                     -104-
<PAGE>

         (c) The right of EMC or its designee to repurchase all the assets of
the Trust Fund described in Subsection 10.01(a)(i) above shall be exercisable
only if (i) the aggregate Stated Principal Balance of the Mortgage Loans at the
time of any such repurchase is less than 20% of the Cut-off Date Balance or (ii)
the Seller, based upon an Opinion of Counsel, has determined that the REMIC
status of REMIC I or REMIC II has been lost or that a substantial risk exists
that such REMIC 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 assets of the Trust Fund
described in Subsection 10.01(a)(i) above .

         (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 assets of the Trust Fund described in 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 Termination Purchase Price. 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 Certificate Principal Balance, 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 Mortgage
Loans are not sufficient to pay all of the Senior 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 Senior Certificates. 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).

                                     -105-

         (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, pursuant to the written
direction of the Securities Administrator and 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 addressed to the Trustee
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
         and REMIC II 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

                                     -106-
<PAGE>

                  (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.

         (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 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 addressed to the Trustee 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 this 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

                                     -108-
<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
addressed to the Trustee 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 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

                                     -109-
<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

                                     -110-
<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.

         evidencing a fractional undivided interest in the distributions
         allocable to the Class __-A 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 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") primarily consisting of conventional adjustable rate mortgage
loans secured by first liens on one- to four- family residential properties
(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,

                                      A-1-2

<PAGE>

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 JPMorgan Chase Bank, 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 period
from and including the preceding Distribution Date (as hereinafter defined) (or
in the case of the first Distribution Date, from the Closing Date) to and
including the day prior to the current Distribution Date on the Certificate
Principal Balance 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 Business Day immediately preceding the related
Distribution Date so long as such Certificate remains in book-entry form (and
otherwise, the close of business on the last Business Day of the month
immediately 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 following the
latest scheduled maturity date of any Mortgage Loan and is not likely to be the
date on which the Certificate Principal Balance 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 Certificate Principal Balance of this Certificate is set forth above.
The Certificate Principal Balance hereof will be reduced to the extent of
distributions allocable to principal hereon.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
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-1-3

<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 of the Servicing Agreements 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 thereof and of the
Servicing Agreements 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 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 (A) the maturity or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and

                                      A-1-4

<PAGE>

disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (B) 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 Stated Principal
Balance of the Mortgage Loans is less than the percentage of the aggregate
Stated 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.

                                  SERIES 2003-1

         evidencing a fractional undivided interest in the distributions
         allocable to the Class M 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 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") primarily consisting of conventional adjustable rate mortgage
loans secured by first liens on one- to four- family residential properties
(collectively, the "Mortgage Loans") sold by Structured Asset Mortgage
Investments Inc. ("SAMI"). The Mortgage

                                      A-2-2

<PAGE>

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 JPMorgan Chase Bank, 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 period
from and including the preceding Distribution Date (as hereinafter defined) (or
in the case of the first Distribution Date, from the Closing Date) to and
including the day prior to the current Distribution Date on the Certificate
Principal Balance 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 Business Day immediately preceding the related
Distribution Date so long as such Certificate remains in book-entry form (and
otherwise, the close of business on the last Business Day of the month
immediately 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 following the
latest scheduled maturity date of any Mortgage Loan and is not likely to be the
date on which the Certificate Principal Balance 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 Certificate Principal Balance of this Certificate is set forth above.
The Certificate Principal Balance hereof will be reduced to the extent of
distributions allocable to principal hereon and any Realized Losses allocable
hereto.

                  Each beneficial owner of a Class M Certificate or any interest
therein shall be deemed to have represented, by virtue of its acquisition or
holding of that Certificate or interest therein, that either (i) it is not a
Plan or investing with "Plan Assets", (ii)(1) it is an insurance company, (2)
the source of funds used to acquire or hold the Certificate or interest therein
is an "insurance company general account," as such term is defined in Prohibited
Transaction Class Exemption ("PTCE") 95-60, and (3) the conditions in Sections I
and III of PTCE 95-60 have been satisfied.

Certificates designated as set forth on the face hereof (the "Certificates").
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

                  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 of the Servicing Agreements 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 thereof and of the
Servicing Agreements 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 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

                                      A-2-4

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 (A) the maturity or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) 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 Stated Principal Balance of the Mortgage Loans is less than the
percentage of the aggregate Stated 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.

                                  SERIES 2003-1

         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 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") primarily consisting of conventional adjustable rate
mortgage loans secured by first liens on one- to four- family residential
properties (collectively, the "Mortgage Loans") sold by Structured Asset
Mortgage Investments Inc. ("SAMI"). The

<PAGE>

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 JPMorgan Chase Bank, 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.

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

                  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 of the month immediately
preceding the month of the related Distribution Date, an amount equal to the
product of the Fractional Undivided Interest evidenced by this Certificate and
the amounts 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 following the latest scheduled maturity date of
any Mortgage Loan.

                  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.

                  No transfer of this Class R-__ Certificate will be made unless
the Trustee has received either (i) an opinion of counsel for the benefit of the
Trustee, the Master Servicer and the Securities

<PAGE>

Administrator and on which they may rely which is acceptable to and in form and
substance satisfactory to the Trustee that the purchase of the Certificate is
permissible under applicable law, will not constitute or result in a non-exempt
prohibited transaction under Section 406 of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA") or Section 4975 of the Internal
Revenue Code (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) a representation letter, in the form as
described by the Agreement, stating that the transferee is not an employee
benefit or other plan subject to the prohibited transaction provisions of ERISA
or Section 4975 of the Code (a "Plan"), or any other person (including an
investment manager, a named fiduciary or a trustee of any Plan) acting, directly
or indirectly, on behalf of or purchasing any Certificate with "plan assets" of
any Plan.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
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 of the Servicing Agreements 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 thereof and of the
Servicing Agreements 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 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.

<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 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 (A) the maturity or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) 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 Stated Principal Balance of the Mortgage Loans is less than the
percentage of the aggregate Stated 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.

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

         properties and 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") primarily consisting of conventional adjustable rate
mortgage loans secured by first liens on one- to four- family residential
properties (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

<PAGE>

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 JPMorgan Chase Bank, 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 period
from and including the preceding Distribution Date (as hereinafter defined) (or
in the case of the first Distribution Date, from the Closing Date) to and
including the day prior to the current Distribution Date on the Notional Amount
hereof at a per annum rate equal to the Pass-Through Rate as set forth in the
Agreement. 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 of the month immediately
preceding the month of the related Distribution Date, an amount equal to the
product of the Fractional Undivided Interest evidenced by this Certificate and
the amount of interest 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 following the latest scheduled maturity date
of any Mortgage Loan and is not likely to be the date on which the 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
Class B-IO Certificates have no Certificate Principal Balance. The Initial
Notional Amount of this Certificate is set forth above.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1 or F-2, as
applicable, and (ii) in all other cases, an Opinion of Counsel satisfactory to
it that such transfer may be made without such registration or qualification
(which Opinion of Counsel shall not

<PAGE>

be an expense of the Trust Fund or of the Seller, the Trustee, the Securities
Administrator or the Master Servicer in their respective capacities as such),
together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Seller nor
the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Securities Administrator, the Seller, the Seller and the Master
Servicer against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

                  No transfer of this Class B-IO Certificate will be made unless
the Trustee and the Securities Administrator have received either (i) an opinion
of counsel acceptable to and in form and substance satisfactory to the Trustee,
the Securities Administrator and the Master Servicer with respect to the
permissibility of such transfer under the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), and Section 4975 of the Internal Revenue Code
(the "Code") and stating, among other things, that the transferee's acquisition
of a Class B-IO Certificate will not constitute or result in a non-exempt
prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or
(ii) a representation letter, in the form as described by the Agreement, stating
that the transferee is not an employee benefit or other plan subject to the
prohibited transaction provisions of ERISA or Section 4975 of the Code (a
"Plan"), or any other person (including an investment manager, a named fiduciary
or a trustee of any Plan) acting, directly or indirectly, on behalf of or
purchasing any Certificate with "plan assets" of any Plan, or (iii) a
certification that the proposed transfer and holding of a certificate and the
servicing, management and 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 ("PTCE") 84-14, PTCE 91-38, PTCE 90-1, PTCE
95-60 or PTCE 96-23 and (ii) will not give rise to any additional fiduciary
duties on the part of the Seller, the Securities Administrator, the Master
Servicer or the Trustee, which will be 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 or unless the transferee provides the Trustee
with an opinion of counsel for the benefit of the Trustee, Master Servicer and
the Securities Administrator and which they may rely which is satisfactory to
the Trustee that the purchase of this certificate is permissible under local
law, will not constitute or result in a non-exempt prohibited transaction under
section 406 of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), or section 4975 of the Code and will not subject the Master Servicer,
the Trustee or the Securities Administrator to any obligation or liability in
addition to those undertaken in the Agreement.

                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
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

<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 of the Servicing Agreements 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 thereof and of the
Servicing Agreements 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 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 (A) the maturity or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and

<PAGE>

disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (B) 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 Stated Principal
Balance of the Mortgage Loans is less than the percentage of the aggregate
Stated 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.

<PAGE>

                  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 XP 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 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") primarily consisting of conventional adjustable rate
mortgage loans secured by first liens on one- to four- family residential
properties (collectively,

                                      A-5-2

<PAGE>

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 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 JPMorgan
Chase Bank, 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.

                  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 of the month immediately
preceding the month of the related Distribution Date, an amount equal to the
product of the Fractional Undivided Interest evidenced by this Certificate and
the amount 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 following the latest scheduled maturity date of
any Mortgage Loan and is not likely to be the date on which the Certificate
Principal Balance 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 Certificate Principal Balance of this Certificate is set forth above.
The Certificate Principal Balance hereof will be reduced to the extent of
distributions allocable to principal hereon.

                  No transfer of this Certificate shall be made unless the
transfer is made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the "1933 Act"), and an effective
registration or qualification under applicable state securities laws, or is made
in a transaction that does not require such registration or qualification. In
the event that such a transfer of this Certificate is to be made without
registration or qualification, the Trustee shall require receipt of (i) if such
transfer is purportedly being made in reliance upon Rule 144A under the 1933
Act, written certifications from the Holder of the Certificate desiring to
effect the transfer, and from such Holder's prospective transferee,
substantially in the forms attached to the Agreement as Exhibit F-1 or F-2, as
applicable, and (ii) in all other cases, an Opinion of Counsel satisfactory to
it that such transfer may be made without such registration or qualification
(which Opinion of Counsel shall not be an expense of the Trust Fund or of the
Seller, the Trustee, the Securities

                                      A-5-3

<PAGE>

Administrator or the Master Servicer in their respective capacities as such),
together with copies of the written certification(s) of the Holder of the
Certificate desiring to effect the transfer and/or such Holder's prospective
transferee upon which such Opinion of Counsel is based. Neither the Seller nor
the Trustee is obligated to register or qualify the Class of Certificates
specified on the face hereof under the 1933 Act or any other securities law or
to take any action not otherwise required under the Agreement to permit the
transfer of such Certificates without registration or qualification. Any Holder
desiring to effect a transfer of this Certificate shall be required to indemnify
the Trustee, the Securities Administrator, the Seller, the Seller and the Master
Servicer against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

                  No transfer of this Class XP Certificate will be made unless
the Trustee and the Securities Administrator have received either (i) an opinion
of counsel acceptable to and in form and substance satisfactory to the Trustee,
the Securities Administrator and the Master Servicer with respect to the
permissibility of such transfer under the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), and Section 4975 of the Internal Revenue Code
(the "Code") and stating, among other things, that the transferee's acquisition
of a Class XP Certificate will not constitute or result in a non-exempt
prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or
(ii) a representation letter, in the form as described by the Agreement, stating
that the transferee is not an employee benefit or other plan subject to the
prohibited transaction provisions of ERISA or Section 4975 of the Code (a
"Plan"), or any other person (including an investment manager, a named fiduciary
or a trustee of any Plan) acting, directly or indirectly, on behalf of or
purchasing any Certificate with "plan assets" of any Plan, or (iii) a
certification that the proposed transfer and holding of a certificate and the
servicing, management and 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 ("PTCE") 84-14, PTCE 91-38, PTCE 90-1, PTCE
95-60 or PTCE 96-23 and (ii) will not give rise to any additional fiduciary
duties on the part of the Seller, the Securities Administrator, the Master
Servicer or the Trustee, which will be 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 or unless the transferee provides the Trustee
with an opinion of counsel for the benefit of the Trustee, Master Servicer and
the Securities Administrator and which they may rely which is satisfactory to
the Trustee that the purchase of this certificate is permissible under local
law, will not constitute or result in a non-exempt prohibited transaction under
section 406 of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), or section 4975 of the Code and will not subject the Master Servicer,
the Trustee or the Securities Administrator to any obligation or liability in
addition to those undertaken in the Agreement.
                  This Certificate is one of a duly authorized issue of
Certificates designated as set forth on the face hereof (the "Certificates").
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 of the Servicing Agreements 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 thereof and of the
Servicing Agreements 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 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 (A) the maturity or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (B) 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

                                      A-5-5

<PAGE>

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 Stated
Principal Balance of the Mortgage Loans is less than the percentage of the
aggregate Stated 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) through (e) above) would constitute a distribution of any
                  Certificate under the Act, that would render the disposition
                  of any Certificate a violation of Section 5 of the Act or any

Dear Ladies and Gentlemen:

         In connection with our purchase of Certificates, we confirm that:

                  (i)      we understand that the Certificates are not being
                           registered under the Securities Act of 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
                           registration requirements of such laws;

                  (ii)     any information we desired concerning the
                           Certificates, including the Certificates, the trust
                           in which the Certificates represent the entire
                           beneficial ownership interest (the "Trust") or any
                           other matter we deemed relevant to our decision to
                           purchase Certificates has been made available to us;

                  (iii)    we are able to bear the economic risk of investment
                           in Certificates; we are an institutional "accredited
                           investor" as defined in Section 501(a) of Regulation
                           D promulgated under the Act and a sophisticated
                           institutional investor;

                  (iv)     we are acquiring Certificates for our own account,
                           not as nominee for any other person, and not with a
                           present view to any distribution or other disposition
                           of the Certificates;

                           in any way disposed of) unless subsequently
                           registered under the Act and any applicable state
                           securities or "Blue Sky" laws or an exemption from
                           the registration requirements of the Act and any
                           applicable state securities or "Blue Sky" laws is
                           available;

                  (vi)     we agree that in the event that at some future time
                           we wish to dispose of or exchange any of the
                           Certificates (such disposition or exchange not being
                           currently foreseen or contemplated), we will not
                           transfer or exchange any of the Certificates unless:

                           FORM OF CUSTODIAL AGREEMENT
                           ---------------------------

         THIS CUSTODIAL AGREEMENT (as amended and supplemented from time to

INC., as company (together with any successor in interest, the "Company"), WELLS

                                WITNESSETH THAT:
                                ---------------

                  WHEREAS, the Company, the Master Servicer and the Trustee have
entered into a Pooling and Servicing Agreement, dated as of April 1, 2003,
relating to the issuance of Bear Stearns ALT-A Trust, Mortgage Pass-Through
Certificates, Series 2003-1 (as in effect on the date of this agreement, the
"Original Pooling and Servicing Agreement," and as amended and supplemented from
time to time, the "Pooling and Servicing Agreement'); and

                  WHEREAS, the Custodian has agreed to act as agent for the
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
hereinafter set forth;

                  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.

<PAGE>

                                   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 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 Seller and 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 Seller and 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

                                       G-2

<PAGE>

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.

         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 missing from 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.

                                       G-3

<PAGE>

                  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 Request for Release shall
be accompanied by an assignment of mortgage, without recourse, representation or
warranty from the Trustee to the Mortgage Loan Seller and the related Mortgage
Note shall be endorsed without recourse, representation or warranty 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, substitution of liability agreement or sale of servicing
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 AS 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

                                       G-4

<PAGE>

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 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.

amounts and any interest thereon belonging to the Mortgage Loan Seller as

agreed to by the Purchaser and the Mortgage Loan Seller (each of the Closing
Date and such later date is referred to as a "MORTGAGE FILE DELIVERY DATE"), the
items of each Mortgage File, PROVIDED, HOWEVER, that in lieu of the foregoing,
the Mortgage Loan 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
Mortgage Loan Seller in time to permit their delivery as specified above, the
Mortgage Loan Seller may deliver a true copy thereof with a certification by the
Mortgage Loan Seller, on the face of such copy, substantially as follows:
"Certified to be a

                                       J-4

<PAGE>

true and correct copy of the original, which has been transmitted for recording"
(y) in lieu of the Security Instrument, assignments to the Trustee or
intervening assignments thereof, if the applicable jurisdiction retains the
originals of such documents (as evidenced by a certification from the Mortgage
Loan Seller to such effect) the Mortgage Loan 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) in lieu of the Mortgage Notes relating to the Mortgage Loans, each
identified in the list delivered by the Purchaser to the Trustee on the Closing
Date and attached hereto as Exhibit 5, the Mortgage Loan Seller may deliver lost
note affidavits and indemnities of the Mortgage Loan Seller; 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 Mortgage Loan
Seller, in lieu of delivering the above documents, may deliver to the Trustee a
certification by the Mortgage Loan Seller or the Master Servicer to such effect.
The Mortgage Loan Seller shall deliver such original documents (including any
original documents as to which certified copies had previously been delivered)
or such certified copies to the Trustee promptly after they are received. The
Mortgage Loan Seller shall cause the Mortgage and intervening assignments, if
any, and the assignment of the Security Instrument to be recorded not later than
180 days after the Closing Date, unless such assignment is not required to be
recorded under the terms set forth in Section 6(a) hereof.

                  (c) The Mortgage Loan Seller and the Purchaser acknowledge
hereunder that all of the Mortgage Loans and the related servicing will
ultimately be assigned to JPMorgan Chase Bank, as Trustee for the
Certificateholders, on the date hereof.

                  SECTION 5.  EXAMINATION OF MORTGAGE FILES.

                  (a) On or before the Mortgage File Delivery Date, the Mortgage
Loan Seller will have made the Mortgage Files available to the Purchaser or its
agent for examination which may be at the offices of the Trustee or the Mortgage
Loan Seller and/or the Mortgage Loan Seller's custodian. The fact that the
Purchaser or its agent has conducted or has failed to conduct any partial or
complete examination of the Mortgage Files shall not affect the Purchaser's
rights to demand cure, repurchase, substitution or other relief as provided in
this Agreement. In furtherance of the foregoing, the Mortgage Loan Seller shall
make the Mortgage Files available to the Purchaser or its agent from time to
time so as to permit the Purchaser to confirm the Mortgage Loan Seller's
compliance with the delivery and recordation requirements of this Agreement and
the Pooling and Servicing Agreement. In addition, upon request of the Purchaser,
the Mortgage Loan Seller agrees to provide to the Purchaser, Bear Stearns and to
any investors or prospective investors in the Certificates information regarding
the Mortgage Loans and their servicing, to make the Mortgage Files available to
the Purchaser, Bear Stearns and to such investors or prospective investors
(which may be at the offices of the Mortgage Loan Seller and/or the Mortgage
Loan Seller's custodian) and to make available personnel knowledgeable about the
Mortgage Loans for discussions with the Purchaser, Bear Stearns and such
investors or prospective investors, upon reasonable request during regular
business hours, sufficient to permit the Purchaser, Bear Stearns and such
investors or potential investors to conduct such due diligence as any such party
reasonably believes is appropriate.

<PAGE>

                  (a) Pursuant to the Pooling and Servicing Agreement, on the
Closing Date the Trustee, for the benefit of the Certificateholders, will review
or cause the Custodian to review items of the Mortgage Files as set forth on
EXHIBIT 1 and will deliver or cause the Custodian to deliver to the Mortgage
Loan Seller an initial certification in the form attached as Exhibit One to the
Custodial Agreement.

                  (b) Pursuant to the Pooling and Servicing Agreement, within 90
days of the Closing Date, the Trustee will review or shall cause the Custodian
to review items of the Mortgage Files as set forth on EXHIBIT 1 and will deliver
to the Mortgage Loan Seller and the Master Servicer an interim certification
substantially in the form of Exhibit Two to the Custodial Agreement.

                  (c) Pursuant to the Pooling and Servicing Agreement, within
180 days of 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 will review or cause the Custodian to review items of the Mortgage
Files as set forth on EXHIBIT 1 and will deliver to the Mortgage Loan Seller and
the Master Servicer a final certification substantially in the form of Exhibit
Three to the Custodial Agreement. If the Trustee is unable to deliver a final
certification with respect to the items listed in EXHIBIT 1 due to any document
that is missing, has not been executed, is unrelated, determined on the basis of
the Mortgagor name, original principal balance and loan number, to the Mortgage
Loans identified in the Final Mortgage Loan Schedule (a "MATERIAL DEFECT"), the
Trustee or the Custodian, as its agent, shall promptly notify the Mortgage Loan
Seller of such Material Defect. The Mortgage Loan Seller shall correct or cure
any such Material Defect within 90 days from the date of notice from the Trustee
or the Custodian, as its agent, of the Material Defect and if the Mortgage Loan
Seller does not correct or cure such Material Defect within such period and such
defect materially and adversely affects the interests of the Certificateholders
in the related Mortgage Loan, the Mortgage Loan Seller will, in accordance with
the terms of the Pooling and Servicing Agreement, within 90 days of the date of
notice, provide the Trustee with a Substitute Mortgage Loan (if within two years
of the Closing Date) or purchase the related Mortgage Loan at the applicable
Purchase 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, repurchase or substitution 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 of Mortgage Loan Seller or a Servicing Officer
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.

                  (d) At the time of any substitution, the Mortgage Loan Seller
shall deliver or cause to be delivered the Substitute Mortgage Loan, the related
Mortgage File and any other documents and payments required to be delivered in
connection with a substitution pursuant to the Pooling and Servicing Agreement.
At the time of any purchase or substitution, the Trustee shall (i) assign to the
Mortgage Loan Seller and cause the Trustee to release the documents (including,
but not limited to, the Mortgage, Mortgage Note and other contents of the
Mortgage File) in the possession of the Trustee relating to the Deleted Mortgage
Loan and (ii) execute and deliver such instruments of transfer or assignment, in
each case without recourse, as shall be necessary to vest in the Mortgage Loan
Seller title to such Deleted Mortgage Loan.

                  SECTION 6.  RECORDATION OF ASSIGNMENTS OF MORTGAGE.

                  (a) The Mortgage Loan Seller shall, promptly after the Closing
Date, cause each Mortgage and each assignment of Mortgage from the Mortgage Loan
Seller to the Trustee, and all unrecorded intervening assignments, if any,
delivered on or prior to the Closing Date, to be recorded in all recording
offices in the jurisdictions where the related Mortgaged Properties are located;
PROVIDED, HOWEVER, the Mortgage Loan Seller need not cause to be recorded any
assignment which relates to a Mortgage Loan if (a) such recordation is not
required by the Rating Agencies or an Opinion of Counsel has been provided to
the Trustee which states that the recordation of such assignment is not
necessary to protect the Trustee's interest in the related Mortgage Loan or (b)
MERS is identified on the Mortgage or a properly recorded assignment of the
Mortgage, as the Mortgagee of record solely as nominee for the Mortgage Loan
Seller and its successors and assigns; PROVIDED, HOWEVER, notwithstanding the
delivery of any Opinion of Counsel, each assignment of Mortgage shall be
submitted for recording by the Mortgage Loan Seller in the manner described
above, at no expense to the Trust Fund or Trustee, 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 a Event of Default, (iii) the occurrence of a bankruptcy,
insolvency or foreclosure relating to the Mortgage Loan Seller and (iv) the
occurrence of a servicing transfer as described in Section 8.02 of the Pooling
and Servicing Agreement.

                  While each such Mortgage or assignment is being recorded, if
necessary, the Mortgage Loan Seller shall leave or cause to be left with the
Trustee a certified copy of such Mortgage or assignment. In the event that,
within 180 days of the Closing Date, a Security Instrument is not recorded
pursuant to the preceding paragraph or the Trustee has not received evidence of
recording with respect to each Mortgage Loan delivered to the Purchaser pursuant
to the terms hereof or as set forth above, the failure to provide evidence of
recording or such Opinion of Counsel (in the alternative, if required) shall be
considered a Material Defect, and the provisions of Section 5(c) and (d) shall
apply. All customary recording fees and reasonable expenses relating to the
recordation of the assignments of mortgage to the Trustee or the Opinion of
Counsel, as the case may be, shall be borne by the Mortgage Loan Seller.

                  (b) It is the express intent of the parties hereto that the
conveyance of the Mortgage Loans by the Mortgage Loan Seller to the Purchaser,
as contemplated by this Agreement be, and be treated as, a sale. It is, further,
not the intention of the parties that such conveyance be deemed a pledge of the
Mortgage Loans by the Mortgage Loan Seller to the Purchaser to secure a debt or
other obligation of the Mortgage Loan Seller. However, in the event that,
notwithstanding

                                       J-7

<PAGE>

the intent of the parties, the Mortgage Loans are held by a court to continue to
be property of the Mortgage Loan Seller, then (a) this Agreement shall also be
deemed to be a security agreement within the meaning of Articles 8 and 9 of the
applicable Uniform Commercial Code; (b) the transfer of the Mortgage Loans
provided for herein shall be deemed to be a grant by the Mortgage Loan Seller to
the Purchaser of a security interest in all of the Mortgage Loan Seller's right,
title and interest in and to the Mortgage Loans and all amounts payable to the
holders of the Mortgage Loans in accordance with the terms thereof and all
proceeds of the conversion, voluntary or involuntary, of the foregoing into
cash, instruments, securities or other property, to the extent the Purchaser
would otherwise be entitled to own such Mortgage Loans and proceeds pursuant to
Section 4 hereof, including all amounts, other than investment earnings, from
time to time held or invested in any accounts created pursuant to the Pooling
and Servicing Agreement, whether in the form of cash, instruments, securities or
other property; (c) the possession by the Purchaser or the Trustee of Mortgage
Notes and such other items of property as constitute instruments, money,
negotiable documents or chattel paper shall be deemed to be "possession by the
secured party" for purposes of perfecting the security interest pursuant to
Section 9-313 (or comparable provision) of the applicable Uniform Commercial
Code; and (d) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,
shall be deemed notifications to, or acknowledgments, receipts or confirmations
from, financial intermediaries, bailees or agents (as applicable) of the
Purchaser for the purpose of perfecting such security interest under applicable
law. Any assignment of the interest of the Purchaser pursuant to any provision
hereof or pursuant to the Pooling and Servicing Agreement shall also be deemed
to be an assignment of any security interest created hereby. The Mortgage Loan
Seller and the Purchaser shall, to the extent consistent with this Agreement,
take such actions as may be reasonably necessary to ensure that, if this
Agreement were deemed to create a security interest in the Mortgage Loans, such
security interest would be deemed to be a perfected security interest of first
priority under applicable law and will be maintained as such throughout the term
of the Pooling and Servicing Agreement.

                  SECTION 7. REPRESENTATIONS AND WARRANTIES OF MORTGAGE LOAN
SELLER CONCERNING THE MORTGAGE LOANS. The Mortgage Loan Seller hereby represents
and warrants to the Purchaser as of the Closing Date or such other date as may
be specified below with respect to each Mortgage Loan being sold by it:

                  (i) the information set forth in the Mortgage Loan Schedule
         hereto is true and correct in all material respects and the information
         provided to the Rating Agencies, including the Mortgage Loan level
         detail, is true and correct according to the Rating Agency
         requirements;

                  (ii) immediately prior to the transfer to the Purchaser, the
         Mortgage Loan Seller was the sole owner of beneficial title and holder
         of each Mortgage and Mortgage Note relating to the Mortgage Loans and
         is conveying the same free and clear of any and all liens, claims,
         encumbrances, participation interests, equities, pledges, charges or
         security interests of any nature and the Mortgage Loan Seller has full
         right and authority to sell or assign the same pursuant to this
         Agreement;

                                       J-8

<PAGE>

                  (iii) to the best of the Mortgage Loan Seller's knowledge,
         each Mortgage Loan at the time it was made complied in all material
         respects with applicable state and federal laws, including, without
         limitation, usury, equal credit opportunity, disclosure and recording
         laws; and, to the best of the Mortgage Loan Seller's knowledge, each
         Mortgage Loan has been serviced in all material respects in accordance
         with applicable state and federal laws, including, without limitation,
         usury, equal credit opportunity, disclosure and recording laws and the
         terms of the related Mortgage Note, the Mortgage and other loan
         documents;

                  (iv) there is no monetary default existing under any Mortgage
         or the related Mortgage Note and there is no material event which, with
         the passage of time or with notice and the expiration of any grace or
         cure period, would constitute a default, breach or event of
         acceleration; and neither the Mortgage Loan Seller, any of its
         affiliates nor any servicer of any related Mortgage Loan has taken any
         action to waive any default, breach or event of acceleration; no
         foreclosure action is threatened or has been commenced with respect to
         the Mortgage Loan;

                  (v) the terms of the Mortgage Note and the Mortgage have not
         been impaired, waived, altered or modified in any respect, except by
         written instruments, (i) if required by law in the jurisdiction where
         the Mortgaged Property is located, or (ii) to protect the interests of
         the Trustee on behalf of the Certificateholders;

                  (vi) no selection procedure reasonably believed by the
         Mortgage Loan Seller to be adverse to the interests of the
         Certificateholders was utilized in selecting the Mortgage Loans;

                  (vii) each Mortgage is a valid and enforceable first lien on
         the property securing the related Mortgage Note and each Mortgaged
         Property is owned by the Mortgagor in fee simple (except with respect
         to common areas in the case of condominiums, PUDs and DE MINIMIS PUDs)
         or by leasehold for a term longer than the term of the related
         Mortgage, subject only to (i) the lien of current real property taxes
         and assessments, (ii) covenants, conditions and restrictions, rights of
         way, easements and other matters of public record as of the date of
         recording of such Mortgage, such exceptions being acceptable to
         mortgage lending institutions generally or specifically reflected in
         the appraisal obtained in connection with the origination of the
         related Mortgage Loan or referred to in the lender's title insurance
         policy delivered to the originator of the related Mortgage Loan and
         (iii) other matters to which like properties are commonly subject which
         do not materially interfere with the benefits of the security intended
         to be provided by such Mortgage;

                  (viii) there is no mechanics' lien or claim for work, labor or
         material affecting the premises subject to any Mortgage which is or may
         be a lien prior to, or equal with, the lien of such Mortgage except
         those which are insured against by the title insurance policy referred
         to in (xiiii) below;

                  (ix) as of the Cut-off Date, to the best of the Mortgage Loan
         Seller's knowledge, there was no delinquent tax or assessment lien
         against the property subject to any Mortgage,

                                      J-9

<PAGE>

         except where such lien was being contested in good faith and a stay had
         been granted against levying on the property;

                  (x) there is no valid offset, defense or counterclaim to any
         Mortgage Note or Mortgage, including the obligation of the Mortgagor to
         pay the unpaid principal and interest on such Mortgage Note;

                  (xi) to the best of the Mortgage Loan Seller's knowledge,
         except to the extent insurance is in place which will cover such
         damage, the physical property subject to any Mortgage is free of
         material damage and is in good repair and there is no proceeding
         pending or threatened for the total or partial condemnation of any
         Mortgaged Property;

                  (xii) to the best of the Mortgage Loan Seller's knowledge, the
         Mortgaged Property and all improvements thereon comply with all
         requirements of any applicable zoning and subdivision laws and
         ordinances;

                  (xiii) a lender's title insurance policy (on an ALTA or CLTA
         form) or binder, or other assurance of title customary in the relevant
         jurisdiction therefor in a form acceptable to Fannie Mae or Freddie
         Mac, was issued on the date that each Mortgage Loan was created by a
         title insurance company which, to the best of the Mortgage Loan
         Seller's knowledge, was qualified to do business in the jurisdiction
         where the related Mortgaged Property is located, insuring the Mortgage
         Loan Seller and its successors and assigns that the Mortgage is a first
         priority lien on the related Mortgaged Property in the original
         principal amount of the Mortgage Loan. The Mortgage Loan Seller is the
         sole insured under such lender's title insurance policy, and such
         policy, binder or assurance is valid and remains in full force and
         effect, and each such policy, binder or assurance shall contain all
         applicable endorsements including a negative amortization endorsement,
         if applicable;

                  (xiv) at the time of origination, each Mortgaged Property was
         the subject of an appraisal which conformed to the underwriting
         requirements of the originator of the Mortgage Loan;

                  (xv) as of the Closing Date, the improvements on each
         Mortgaged Property securing a Mortgage Loan is insured (by an insurer
         which is acceptable to the Mortgage Loan Seller) against loss by fire
         and such hazards as are covered under a standard extended coverage
         endorsement in the locale in which the Mortgaged Property is located,
         in an amount which is not less than the lesser of the maximum insurable
         value of the improvements securing such Mortgage Loan or the
         outstanding principal balance of the Mortgage Loan, but in no event in
         an amount less than an amount that is required to prevent the Mortgagor
         from being deemed to be a co-insurer thereunder; if the improvement on
         the Mortgaged Property is a condominium unit, it is included under the
         coverage afforded by a blanket policy for the condominium project; if
         upon origination of the related Mortgage Loan, the improvements on the
         Mortgaged Property were in an area identified as a federally designated
         flood area, a flood insurance policy is in effect in an amount
         representing coverage not less than the least of (i) the outstanding
         principal balance of the Mortgage Loan, (ii) the restorable cost of
         improvements located on such Mortgaged Property or (iii)

                                      J-10

<PAGE>

         the maximum coverage available under federal law; and each Mortgage
         obligates the Mortgagor thereunder to maintain the insurance referred
         to above at the Mortgagor's cost and expense;

                  (xvi) each Mortgage Loan constitutes a "qualified mortgage"
         under Section 860G(a)(3)(A) of the Code and Treasury Regulation Section
         1.8600-2(a)(1);

                  (xvii) each Mortgage Loan was originated or funded by (a) a
         savings and loan association, savings bank, commercial bank, credit
         union, insurance company or similar institution which is supervised and
         examined by a federal or state authority (or originated by (i) a
         subsidiary of any of the foregoing institutions which subsidiary is
         actually supervised and examined by applicable regulatory authorities
         or (ii) a mortgage loan correspondent of any of the foregoing and that
         was originated pursuant to the criteria established by any of the
         foregoing) or (b) a mortgagee approved by the Secretary of Housing and
         Urban Development pursuant to sections 203 and 211 of the National
         Housing Act, as amended;

                  (xviii) none of the Mortgage Loans are (a) loans subject to 12
         CFR Part 226.31, 12 CFR Part 226.32 or 12 CFR Part 226.34 of Regulation
         Z, the regulation implementing TILA, which implements the Home
         Ownership and Equity Protection Act of 1994, as amended or (b)
         classified and/or defined as a "high cost", "covered", or "predatory"
         loan under any other state, federal or local law or regulation or
         ordinance, including, but not limited to, the States of Georgia or
         North Carolina, or the City of New York; and

                  (xxix) the information set forth in Schedule A of the
         Prospectus Supplement with respect to the Mortgage Loans is true and
         correct in all material respects.

                  It is understood and agreed that the representations and
warranties set forth in this Section 7 will inure to the benefit of the
Purchaser, its successors and assigns, notwithstanding any restrictive or
qualified endorsement on any Mortgage Note or assignment of Mortgage or the
examination of any Mortgage File. Upon any substitution for a Mortgage Loan, the
representations and warranties set forth above shall be deemed to be made by the
Mortgage Loan Seller as to any Substitute Mortgage Loan as of the date of
substitution.

                  Upon discovery or receipt of notice by the Mortgage Loan
Seller, the Purchaser or the Trustee of a breach of any representation or
warranty of the Mortgage Loan Seller set forth in this Section 7 which
materially and adversely affects the value of the interests of the Purchaser,
the Certificateholders or the Trustee in any of the Mortgage Loans delivered to
the Purchaser pursuant to this Agreement, the party discovering or receiving
notice of such breach shall give prompt written notice to the others. In the
case of any such breach of a representation or warranty set forth in this
Section 7, within 90 days from the date of discovery by the Mortgage Loan
Seller, or the date the Mortgage Loan Seller is notified by the party
discovering or receiving notice of such breach (whichever occurs earlier), the
Mortgage Loan Seller will (i) cure such breach in all material respects, (ii)
purchase the affected Mortgage Loan at the applicable Purchase Price or (iii) if
within two years of the Closing Date, substitute a qualifying Substitute
Mortgage Loan in exchange for such Mortgage Loan. The obligations of the
Mortgage Loan Seller to cure, purchase or substitute

                                      J-11

<PAGE>

a qualifying Substitute Mortgage Loan shall constitute the Purchaser's, the
Trustee's and the Certificateholder's sole and exclusive remedy under this
Agreement or otherwise respecting a breach of representations or warranties
hereunder with respect to the Mortgage Loans, except for the obligation of the
Mortgage Loan Seller to indemnify the Purchaser for such breach as set forth in
and limited by Section 13 hereof.

                  Any cause of action against the Mortgage Loan Seller or
relating to or arising out of a breach by the Mortgage Loan Seller of any
representations and warranties made in this Section 7 shall accrue as to any
Mortgage Loan upon (i) discovery of such breach by the Mortgage Loan Seller or
notice thereof by the party discovering such breach and (ii) failure by the
Mortgage Loan Seller to cure such breach, purchase such Mortgage Loan or
substitute a qualifying Substitute Mortgage Loan pursuant to the terms hereof.

                  SECTION 8. REPRESENTATIONS AND WARRANTIES CONCERNING THE
MORTGAGE LOAN SELLER. As of the date hereof and as of the Closing Date, the

         to enter into this Agreement and to consummate the transactions
         contemplated hereby;

         other similar laws affecting the enforcement of the rights of creditors
         generally);

                  (f) there are no actions, suits or proceedings pending or, to

         governmental body so as to materially and adversely affect the
         transactions contemplated by this Agreement; and

                  (g) the Mortgage Loan Seller's Information as identified in
         Exhibit 3 does not include any untrue statement of a material fact or
         omit to state a material fact necessary in order to make the statements
         made, in light of the circumstances under which they were made, not

the right to assign the Mortgage Loans and any or all of its interest under this
Agreement to the Trustee without the consent of the Mortgage Loan Seller, and,

obligations of the Purchaser hereunder; PROVIDED, HOWEVER, the Purchaser shall
remain entitled to the benefits set forth in Sections 11, 13 and 17 hereto and
as provided in Section 2(a). Notwithstanding the foregoing, the sole and
exclusive right and remedy of the Trustee with respect to a breach of

substitution obligations of the Mortgage Loan Seller contained in Sections 5 and

Seller submitted pursuant hereto, shall remain operative and in full force and
effect and shall survive delivery of the Mortgage Loans to the Purchaser (and by
the Purchaser to the Trustee). Subsequent to the delivery of the Mortgage Loans
to the Purchaser, the Mortgage Loan Seller's representations and warranties
contained herein with respect to the Mortgage Loans shall be deemed to relate to
the Mortgage Loans actually delivered to the Purchaser and included in the Final
Mortgage Loan Schedule and any Substitute Mortgage Loan and not to those

Section 3 hereof prior to the Closing.

                  SECTION 17. SEVERABILITY. If any provision of this Agreement

modified in any manner without the prior written consent of each party.

                  SECTION 20. GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED TO
HAVE BEEN MADE AND PERFORMED IN THE STATE OF NEW YORK AND SHALL BE INTERPRETED
IN ACCORDANCE WITH THE LAWS OF SUCH STATE, WITHOUT REGARD TO CONFLICT OF LAWS

enforceable by the Mortgage Loan Seller and the Purchaser and their permitted
successors and assigns. The Mortgage Loan Seller acknowledges and agrees that
the Purchaser may assign its rights under this Agreement (including, without
limitation, with respect to the Mortgage Loan Seller's representations and
warranties respecting the Mortgage Loans) to the Trustee. Any person into which
the Mortgage Loan Seller may be merged or consolidated (or any person resulting
from any merger or consolidation involving the Mortgage Loan Seller), any person
resulting from a change in form of the Mortgage Loan Seller or any person
succeeding to the business of the Mortgage Loan Seller, shall be considered the
"successor" of the Mortgage Loan Seller hereunder and shall be considered a
party hereto without the execution or filing of any paper or any further act or
consent on the part of any party hereto. Except as provided in the two preceding
sentences, this Agreement cannot be assigned, pledged or hypothecated by either
party hereto without the written consent of the other parties to this Agreement
and any such assignment or purported assignment shall be deemed null and void.

                  SECTION 23. THE MORTGAGE LOAN SELLER. The Mortgage Loan Seller
will keep in full effect all rights as are necessary to perform their respective
obligations under this Agreement.

entire agreement and understanding between the parties with respect to the
subject matter hereof, and supersedes all prior and contemporaneous agreements,
understandings, inducements and conditions, express or implied, oral or written,
of any nature whatsoever with respect to the subject matter hereof.

                  SECTION 25. NO PARTNERSHIP. Nothing herein contained shall be
deemed or construed to create a partnership or joint venture between the parties
hereto.
