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

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

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

         The Mortgage Loans will have an Outstanding Principal Balance as of the
Cut-off Date, after deducting all Scheduled Principal due on or before the
Cut-off Date, of approximately $575,627,269. 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:

                  (i) the Senior Percentage of all scheduled payments of
         principal allocated to the Scheduled Principal Balance due on each
         Outstanding Mortgage Loan on the related Due Date as specified in the
         amortization schedule at the time applicable thereto (after adjustments
         for previous Principal Prepayments but before any adjustment to such
         amortization schedule by reason of any bankruptcy or similar proceeding
         or any moratorium or similar waiver or grace period);

                    (ii) the applicable Senior Prepayment Percentage of all
         Principal Prepayments in part received during the related
         Prepayment Period;

                  (iii) the applicable Senior Prepayment Percentage of the
         Scheduled Principal Balance of each Mortgage Loan which was the subject
         of a Principal Prepayment in full during the related Prepayment Period;

                  (iv) the lesser of (a) the applicable Senior Prepayment
         Percentage of (A) all Net Liquidation Proceeds, allocable to principal
         received in respect of each Mortgage Loan which became a Liquidated
         Mortgage Loan during the related Prepayment Period (other than Mortgage
         Loans described in the immediately following clause (B)) and (B) the
         Scheduled Principal Balance of each Mortgage Loan purchased by an
         insurer from the Trustee during the related Prepayment Period pursuant
         to the related Primary Mortgage Insurance Policy; and (b) the
         applicable Senior Percentage of the Scheduled Principal Balance of each

         (a) the Scheduled Principal Balance of each Mortgage Loan or related
         REO Property which was purchased by the Mortgage Loan Seller on such
         Distribution Date and (b) the excess, if any, of the Scheduled
         Principal Balance of a Mortgage Loan that has been replaced by the
         Mortgage Loan Seller with a Substitute Mortgage Loan pursuant to
         Section 2.04 of this Agreement on such Distribution Date over the
         Scheduled Principal Balance of such Substitute Mortgage Loan.

         Senior Percentage: Initially, 92.75%. On any Distribution Date, the
lesser of (i) 100% and (ii) the percentage (carried to six places rounded up)

Scheduled Principal Balance of the Mortgage Loans as of the beginning of the
related Due Period.

         Senior Prepayment Percentage: On any Distribution Date occurring during
the periods set forth below, as follows:

Period (dates inclusive)              Senior Prepayment Percentage

September 19, 2002 - August 19, 2012  100%
September 19, 2012 - August 19, 2013  Senior Percentage plus 70% of the Senior
                                      Mezzanine and Subordinate Percentage
September 19, 2013 - August 19, 2014  Senior Percentage plus 60% of the Senior
                                      Mezzanine and Subordinate Percentage
September 19, 2014 - August 19, 2015  Senior Percentage plus 40% of the Senior
                                      Mezzanine and Subordinate Percentage
September 19, 2015 - August 19, 2016  Senior Percentage plus 20% of the Senior
                                      Mezzanine and Subordinate Percentage
September 19, 2016 and thereafter     Senior Percentage

                                      -23-
<PAGE>

         In addition, no reduction of the Senior Prepayment Percentage shall
occur on any Distribution Date unless, as of the last day of the month preceding
such Distribution Date, (A) the aggregate Scheduled Principal Balance of the
Mortgage Loans delinquent 60 days or more (including for this purpose any such
Mortgage Loans in foreclosure and Mortgage Loans with respect to which the
related Mortgaged Property has been acquired by the Trust), averaged over the
last six months, as a percentage of the aggregate Current Principal Amount of
the Senior Mezzanine Certificates and Subordinate Certificates does not exceed
50%; and (B) cumulative Realized Losses on the Mortgage Loans do not exceed (a)
30% of the Original Senior Mezzanine and Subordinate Principal Balance if such
Distribution Date occurs between and including September 2012 and August 2013,
(b) 35% of the Original Senior Mezzanine and Subordinate Principal Balance if
such Distribution Date occurs between and including September 2013 and August
2014, (c) 40% of the Original Senior Mezzanine and Subordinate Principal Balance
if such Distribution Date occurs between and including September 2014 and August
2015, (d) 45% of the Original Senior Mezzanine and Subordinate Principal Balance
if such Distribution Date occurs between and including September 2015 and August
2016, and (e) 50% of the Original Senior Mezzanine and Subordinate Principal
Balance if such Distribution Date occurs during or after September 19, 2016.

         In addition, if the current weighted average Senior Mezzanine and
Subordinate Percentage is equal to or greater than two times the initial
weighted average Senior Mezzanine and Subordinate Percentage for the
Certificates, and (a) the aggregate Scheduled Principal Balance of the Mortgage
Loans delinquent 60 days or more (including for this purpose any such Mortgage
Loans in foreclosure and such Mortgage Loans with respect to which the related
Mortgaged Property has been acquired by the Trust), averaged over the last six
months, as a percentage of the aggregate Current Principal Amount of the Senior
Mezzanine and Subordinate Certificates does not exceed 50% and (b)(i) prior to
the Distribution Date in September 2005, cumulative Realized Losses on the
Mortgage Loans do not exceed 20% of the Original Senior Mezzanine and
Subordinate Principal Balance and (ii) on or after the Distribution Date in
September 2005, cumulative Realized Losses on the Mortgage Loans do not exceed
30% of the Original Senior Mezzanine and Subordinate Principal Balance, then, in
each case, the Senior Prepayment Percentage for such Distribution Date will
equal the Senior Percentage; provided, however, if the current weighted average
Senior Mezzanine and Subordinate Percentage for the Certificates is equal to or
greater than two times the initial weighted average Senior Mezzanine and
Subordinate Percentage for the Certificates prior to September 19, 2005 and the
above delinquency and loss tests are met, then the Senior Prepayment Percentage
for such Distribution Date will equal the Senior Percentage plus 50% of the
Senior Mezzanine and Subordinate Percentage.

         Notwithstanding the foregoing, if on any Distribution Date the Senior
Percentage exceeds the Senior Percentage as of the Cut-Off Date, the Senior
Prepayment Percentage for such Distribution Date will equal 100%. On the
Distribution Date on which the Current Principal Amounts of the Senior
Certificates are reduced to zero, the Senior Prepayment Percentage shall be the
minimum percentage sufficient to effect such reduction and thereafter shall be
zero.

         Section 1.02.     Calculation of LIBOR.

         LIBOR applicable to the calculation of the Pass-Through Rate on the
Adjustable Rate Certificates for any Interest Accrual Period will be determined
on each Interest Determination Date. On each Interest Determination Date, LIBOR
shall be established by the Securities Administrator and, as to any Interest
Accrual Period, will equal the rate for one month United States dollar deposits
that appears on the Telerate Screen Page 3750 as of 11:00 a.m., London time, on
such Interest Determination Date. "Telerate Screen Page 3750" means the display
designated as page 3750 on the Telerate Service (or such other page as may
replace page 3750 on that service for the purpose of displaying London interbank
offered rates of major banks). If such rate does not appear on such page (or
such other page as may replace that page on that service, or if such service is
no longer offered, LIBOR shall be so established by use of such other service
for displaying LIBOR or comparable rates as may be reasonably selected by the
Securities Administrator), the rate will be the Reference Bank Rate. The
"Reference Bank Rate" will be determined on the basis of the rates at which
deposits in U.S. Dollars are offered by the reference banks (which shall be any
three major banks that are engaged in transactions in the London interbank
market, selected by the Securities Administrator) as of 11:00 a.m., London time,
on the Interest Determination Date to prime banks in the London interbank market
for a period of one month in amounts approximately equal to the aggregate
Current Principal Amount of the Adjustable Rate Certificates then outstanding.
The Securities Administrator will request the principal London office of each of
the reference banks to provide a quotation of its rate. If at least two such
quotations are provided, the rate will be the arithmetic mean of the quotations
rounded up to the nearest whole multiple of 0.03125%. If on such date fewer than
two quotations are provided as requested, the rate will be the arithmetic mean
of the rates quoted by one or more major banks in New York City, selected by the
Securities Administrator, as of 11:00 a.m., New York City time, on such date for
loans in U.S. Dollars to leading European banks for a period of one month in
amounts approximately equal to the aggregate Current Principal Amount of the

                                      -27-
<PAGE>

Adjustable Rate Certificates then outstanding. If no such quotations can be
obtained, the rate will be LIBOR for the prior Distribution Date; PROVIDED
HOWEVER, if, under the priorities described above, LIBOR for a Distribution Date
would be based on LIBOR for the previous Distribution Date for the third
consecutive Distribution Date, the Securities Administrator shall select an
alternative comparable index (over which the Securities Administrator e has no
control), used for determining one-month Eurodollar lending rates that is
calculated and published (or otherwise made available) by an independent party.
The establishment of LIBOR by the Securities Administrator on any Interest
Determination Date and the Securities Administrator's subsequent calculation of
the Pass- Through Rate applicable to the Adjustable Rate Certificates for the
relevant Interest Accrual Period, in the absence of manifest error, will be
final and binding. Promptly following each Interest Determination Date the
Securities Administrator shall supply the Master Servicer with the results of
its determination of LIBOR on such date. Furthermore, the Securities
Administrator will supply to any Certificateholder so calling the Securities
Administrator at (301) 815-6600 and requesting the Pass-Through Rate on the
Adjustable Rate Certificates for the current and the immediately preceding
Interest Accrual Period.

                          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 or Subsequent Cut-off Date, as applicable, but excluding
any payments of principal and interest due on or prior to the Cut-off Date or
Subsequent Cut-off Date, as applicable; (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 Distribution Account, (iii) such assets relating to the Mortgage Loans as
from time to time may be held by the Servicer in Protected Accounts and the
Trustee in the Distribution Account for the benefit of the Trustee on behalf of
the Certificateholders, (iv) any REO Property, (v) the Required Insurance
Policies and any amounts paid or payable by the insurer under any Insurance
Policy (to the extent the mortgagee has a claim thereto), (vi) the Mortgage Loan
Purchase Agreement to the extent provided in Subsection 2.03(a), (vii) the
rights with respect to the Servicing Agreement as assigned to the Trustee on
behalf of the Certificateholders by the Assignment Agreements, and (viii) any
proceeds of the foregoing. Although it is the intent of the parties to this
Agreement that the conveyance of the Seller's right, title and interest in and
to the Mortgage Loans and other assets in the Trust Fund pursuant to this
Agreement shall constitute a purchase and sale and not a loan, in the event that
such conveyance is deemed to be a loan, it is the intent of the parties to this
Agreement that the Seller shall be deemed to have granted to the Trustee a first
priority perfected security interest in all of the Seller's right, title and
interest in, to and under the Mortgage Loans and other assets in the Trust Fund,
and that this Agreement shall constitute a security agreement under applicable
law.

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

                                      -29-
<PAGE>

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

         Section 2.02. Acceptance of Mortgage Loans by Trustee. (a) The Trustee
acknowledges the sale, transfer and assignment of the Trust to it by the Seller
and receipt of, subject to further review and the exceptions which may be noted
pursuant to the procedures described below, and declares that it holds, the
documents (or certified copies thereof) delivered to it pursuant to Section
2.01, and declares that it will continue to hold those documents and any
amendments, replacements or supplements thereto and all other assets of the
Trust Fund delivered to it as Trustee in trust for the use and benefit of all
present and future Holders of the Certificates. On the Closing Date, with
respect to the Mortgage Loans, or the Subsequent Transfer Date, with respect to
the Subsequent

                                      -30-
<PAGE>

Mortgage Loans, the Custodian, shall acknowledge with respect to each Mortgage
Loan by an Initial Certification substantially in the form of Exhibit One to the
Custodial Agreement receipt of the Mortgage File, but without review of such
Mortgage File, except to the extent necessary to confirm that such Mortgage File
contains the related Mortgage Note or lost note affidavit. No later than 90 days
after the Closing Date (or, within 90 days of the Subsequent Transfer Date, with
respect to the Subsequent Mortgage Loans, or with respect to any Substitute
Mortgage Loan, within five Business Days after the receipt by the Trustee or
Custodian thereof), the Trustee agrees, for the benefit of the
Certificateholders, to review or cause to be reviewed by the Custodian on its
behalf (under the Custodial Agreement), each Mortgage File delivered to it and
to execute and deliver, or cause to be executed and delivered, to the Seller and
the Master Servicer an Interim Certification substantially in the form annexed
as Exhibit Two to the Custodial Agreement. In conducting such review, the
Trustee or Custodian will ascertain whether all required documents have been
executed and received, and based on the Mortgage Loan Schedule, whether those
documents relate, determined on the basis of the Mortgagor name, original
principal balance and loan number, to the Mortgage Loans it has received, as
identified in the Mortgage Loan Schedule. In performing any such review, the
Trustee or the Custodian, as its agent, may conclusively rely on the purported
due execution and genuineness of any such document and on the purported
genuineness of any signature thereon. If the Trustee or the Custodian, as its
agent, finds any document constituting part of the Mortgage File not to have
been executed or received, or to be unrelated to the Mortgage Loans identified
in Exhibit B or to appear to be defective on its face, the Trustee or the
Custodian, as its agent, shall promptly notify the Mortgage Loan Seller. In
accordance with the Mortgage Loan Purchase Agreement (or the Subsequent Mortgage
Loan Purchase Agreement, with respect to the Subsequent Mortgage Loans), the
Mortgage Loan Seller shall correct or cure any such defect within ninety (90)
days from the date of notice from the Trustee or the Custodian, as its agent, of
the defect and if the Mortgage Loan Seller fails to correct or cure the defect
within such period, and such defect materially and adversely affects the
interests of the Certificateholders in the related Mortgage Loan, the Trustee or
the Custodian, as its agent, shall enforce the Mortgage Loan Seller's obligation
pursuant to the Mortgage Loan Purchase Agreement, within 90 days from the
Trustee's or the Custodian's notification, to purchase such Mortgage Loan at the
Repurchase Price; provided that, if such defect would cause the Mortgage Loan to
be other than a "qualified mortgage" as defined in Section 860G(a)(3) of the
Code, any such cure or repurchase must occur within 90 days from the date such
breach was discovered; PROVIDED, HOWEVER, that if such defect relates solely to
the inability of the Mortgage Loan Seller to deliver the original Security
Instrument or intervening assignments thereof, or a certified copy because the
originals of such documents, or a certified copy have not been returned by the
applicable jurisdiction, the Mortgage Loan Seller shall not be required to
purchase such Mortgage Loan if the Mortgage Loan Seller delivers such original
documents or certified copy promptly upon receipt, but in no event later than
360 days after the Closing Date. The foregoing repurchase obligation shall not
apply in the event that the Mortgage Loan Seller cannot deliver such original or
copy of any document submitted for recording to the appropriate recording office
in the applicable jurisdiction because such document has not been returned by
such office; provided that the Mortgage Loan Seller shall instead deliver a
recording receipt of such recording office or, if such receipt is not available,
a certificate confirming that such documents have been accepted for recording,
and delivery to the Trustee or the Custodian, as its agent, shall be effected by
the Mortgage Loan Seller within thirty days of its receipt of the original
recorded document.

                                      -31-

         (b) No later than 180 days after the Closing Date, the Trustee or the
Custodian, as its agent, will review, for the benefit of the Certificateholders,
the Mortgage Files delivered to it and will execute and deliver or cause to be
executed and delivered to the Seller a Final Certification substantially in the
form annexed as Exhibit Three to the Custodial Agreement. In conducting such
review, the Trustee or the Custodian, as its agent, will ascertain whether an
original of each document required to be recorded has been returned from the
recording office with evidence of recording thereon or a certified copy has been
obtained from the recording office. If the Trustee or the Custodian, as its
agent, finds any document constituting part of the Mortgage File has not been
received, or to be unrelated, determined on the basis of the Mortgagor name,
original principal balance and loan number, to the Mortgage Loans identified in
Exhibit B or to appear defective on its face, the Trustee or the Custodian, as
its agent, shall promptly notify the Mortgage Loan Seller (PROVIDED, HOWEVER,
that with respect to those documents described in subsection (b)(iv), (b)(v) and
(b)(vii) of Section 2.01, the Trustee's obligations shall extend only to the
documents actually delivered pursuant to such subsections). In accordance with
the Mortgage Loan Purchase Agreement (or the Subsequent Mortgage Loan Purchase
Agreement, with respect to the Subsequent Mortgage Loans), the Mortgage Loan
Seller shall correct or cure any such defect or EMC shall deliver to the Trustee
an Opinion of Counsel to the effect that such defect does not materially or
adversely affect the interests of Certificateholders in such Mortgage Loan
within 90 days from the date of notice from the Trustee of the defect and if the
Mortgage Loan Seller is unable to cure such defect within such period, and if
such defect materially and adversely affects the interests of the
Certificateholders in the related Mortgage Loan, the Trustee shall enforce the
Mortgage Loan Seller's obligation under the Mortgage Loan Purchase Agreement to
purchase such Mortgage Loan at the Repurchase Price, PROVIDED, HOWEVER, that if
such defect relates solely to the inability of the Mortgage Loan Seller to
deliver the original Security Instrument or intervening assignments thereof, or
a certified copy, because the originals of such documents or a certified copy,
have not been returned by the applicable jurisdiction, the Mortgage Loan Seller
shall not be required to purchase such Mortgage Loan, if the Mortgage Loan
Seller delivers such original documents or certified copy promptly upon receipt,
but in no event later than 360 days after the Closing Date.

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

                                      -32-
<PAGE>

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

         (b) If the Seller, the Securities Administrator or the Trustee
discovers a breach of any of the representations and warranties set forth in the
Mortgage Loan Purchase Agreement (or the Subsequent Mortgage Loan Purchase
Agreement, with respect to the Subsequent Mortgage Loans), 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 the Subsequent Mortgage Loan Purchase Agreement, with
respect to the Subsequent Mortgage Loans) 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 the Mortgage Loan Purchase Agreement (or
the Subsequent Mortgage Loan Purchase Agreement, with respect to the Subsequent
Mortgage Loans) or Section 2.04 of this Agreement, as applicable, and the
Mortgage Loan or the related property acquired with respect thereto has been
sold, then the Mortgage Loan Seller, shall pay, in lieu of the Repurchase Price,
any excess of the Repurchase Price over the Net Liquidation Proceeds received
upon such sale. (If the Net Liquidation Proceeds exceed the Repurchase Price,
any excess shall be paid to the Mortgage Loan Seller, to the extent not required
by law to be paid to the borrower.) Any such purchase by the Mortgage Loan
Seller shall be made by providing an amount equal to the Repurchase Price to the
Trustee for deposit in the Distribution Account and written notification
detailing the components of such Repurchase Price to the Trustee and the Master
Servicer. The Seller shall notify the Trustee and submit to the Trustee or the
Custodian, as its agent, a Request for Release in the form of Exhibit D attached
hereto, and the Trustee shall release, or the Trustee shall cause the Custodian
to release, to the Mortgage Loan Seller, the related Mortgage File and the
Trustee shall execute and deliver all instruments of transfer or assignment
furnished to it by the Mortgage Loan Seller, without recourse, as are necessary
to vest in the Mortgage Loan Seller title to and rights under the Mortgage Loan
or any property acquired with respect thereto. Such purchase shall be deemed to
have occurred on the date on which the Repurchase Price in available funds is
received by the Trustee. The Trustee shall amend the Mortgage Loan Schedule to
reflect such repurchase and shall promptly notify the Master

                                      -33-
<PAGE>

Servicer and the Rating Agencies of such amendment. Enforcement of the
obligation of the Mortgage Loan Seller to purchase (or substitute a Substitute
Mortgage Loan for) any Mortgage Loan or any property acquired with respect
thereto (or pay the Repurchase Price as set forth in the above proviso) as to
which a breach has occurred and is continuing shall constitute the sole remedy
respecting such breach available to the Certificateholders or the Trustee on
their behalf.

         Section 2.04. Substitution of Mortgage Loans. Notwithstanding anything
to the contrary in this Agreement, in lieu of purchasing a Mortgage Loan
pursuant to the Mortgage Loan Purchase Agreement (or the Subsequent Mortgage
Loan Purchase Agreement, with respect to the Subsequent Mortgage Loans) 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 the Subsequent Mortgage Loan
Purchase Agreement, with respect to the Subsequent Mortgage Loans) 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 the Subsequent Mortgage
Loan

                                      -34-
<PAGE>

Purchase Agreement, with respect to the Subsequent Mortgage Loans) or Section
2.04 of this Agreement, as applicable, and shall execute and deliver all
instruments of transfer or assignment, without recourse, in form as provided to
it as are necessary to vest in the Mortgage Loan Seller title to and rights
under any Mortgage Loan released pursuant to the Mortgage Loan Purchase
Agreement (or the Subsequent Mortgage Loan Purchase Agreement, with respect to
the Subsequent Mortgage Loans) 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 (or the Subsequent Mortgage Loan Purchase Agreement, with respect to
the Subsequent Mortgage Loans) 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 Interests. The Trustee acknowledges receipt of the
REMIC I Regular Interests (which are uncertificated) and the other assets of
REMIC II and declares that it holds and will hold the same in trust for the
exclusive use and benefit of the holders of the REMIC II Certificates.

         Section  2.06.    Representations and Warranties Concerning the Seller.
The Seller hereby represents and warrants to the Trustee, the Master Servicer
and the Securities Administrator as follows:

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

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

                                      -35-
<PAGE>

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

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

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

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

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

         Section 2.07.     Conveyance of the Subsequent Mortgage Loans.

         (a) Subject to the conditions set forth in paragraph (b) below in
consideration of the Trustee's delivery on the Subsequent Transfer Dates to or
upon the written order of the Seller of all or a portion of the balance of funds
in the Pre-Funding Account, the Seller shall on any Subsequent Transfer Date
sell, transfer, assign, set over and convey without recourse to the Trust Fund
but

                                      -36-
<PAGE>

subject to the other terms and provisions of this Agreement all of the right,
title and interest of the Seller in and to (i) the Subsequent Mortgage Loans
identified on the Mortgage Loan Schedule attached to the related Subsequent
Transfer Instrument delivered by the Seller on such Subsequent Transfer Date,
(ii) all interest accruing thereon on and after the Subsequent Cut-off Date and
all collections in respect of interest and principal due after the Subsequent
Cut-off Date and (iii) all items with respect to such Subsequent Mortgage Loans
to be delivered pursuant to Section 2.01 and the other items in the related
Mortgage Files; provided, however, that the Seller reserves and retains all
right, title and interest in and to principal received and interest accruing on
the Subsequent Mortgage Loans prior to the related Subsequent Cut-off Date. The
transfer to the Trustee for deposit in the mortgage pool by the Seller of the
Subsequent Mortgage Loans identified on the Mortgage Loan Schedule shall be
absolute and is intended by the Seller, the Mortgage Loan Seller, the Master
Servicer, the Securities Administrator, the Trustee and the Certificateholders
to constitute and to be treated as a sale of the Subsequent Mortgage Loans by
the Seller to the Trust Fund. The related Mortgage File for each Subsequent
Mortgage Loan shall be delivered to the Trustee at least three (3) Business Days
prior to the related Subsequent Transfer Date.

         The purchase price paid by the Trustee from amounts released from the
Pre-Funding Account shall be one-hundred percent (100%) of the aggregate
Scheduled Principal Balance of the Subsequent Mortgage Loans so transferred (as
identified on the Mortgage Loan Schedule provided by the Seller). This Agreement
shall constitute a fixed-price purchase contract in accordance with Section
860G(a)(3)(A)(ii) of the Code.

         (b) The Seller shall transfer to the Trustee for deposit in the
mortgage pool the Subsequent Mortgage Loans and the other property and rights
related thereto as described in paragraph (a) above, and the Trustee shall
release funds from the Pre-Funding Account, only upon the satisfaction of each
of the following conditions on or prior to the related Subsequent Transfer Date:

                  (i) the Seller shall have delivered to the Trustee a duly
         executed Subsequent Transfer Instrument, which shall include a Mortgage
         Loan Schedule listing the Subsequent Mortgage Loans, and the Mortgage
         Loan Seller shall cause to be delivered a computer file containing such
         Mortgage Loan Schedule to the Trustee at least three (3) Business Days
         prior to the related Subsequent Transfer Date;

                  (ii) as of each Subsequent Transfer Date, as evidenced by
         delivery of the Subsequent Transfer Instrument, substantially in the
         form of Exhibit K, the Seller shall not be insolvent nor shall it have
         been rendered insolvent by such transfer nor shall it be aware of any
         pending insolvency;

                  (iii)    such sale and transfer shall not result in a material
         adverse tax consequence to the Trust Fund or the Certificateholders;

                  (iv) the Pre-Funding Period shall not have terminated;

                  (v) the Seller shall not have selected the Subsequent
         Mortgage  Loans in a manner that it believed to be adverse to the
         interests of the Certificateholders; and

                                      -37-
<PAGE>

                  (vi) the Seller shall have delivered to the Trustee a
         Subsequent Transfer Instrument confirming the satisfaction of the
         conditions precedent specified in this Section 2.08 and, pursuant to
         the Subsequent Transfer Instrument, assigned to the Trustee without
         recourse for the benefit of the Certificateholders all the right, title
         and interest of the Seller, in, to and under the Subsequent Mortgage
         Loan Purchase Agreement, to the extent of the Subsequent Mortgage
         Loans.

                                   ARTICLE III

                 Administration and Servicing of Mortgage Loans

         Section 3.01. Master Servicer. The Master Servicer shall supervise,
monitor and oversee the obligation of the Servicer 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 Servicer's and Master Servicer's records, and based on such
reconciled and corrected information, prepare the statements specified in
Section 6.04 and any other information and statements required hereunder. The
Master Servicer shall reconcile the results of its Mortgage Loan monitoring with
the actual remittances of the Servicer to the Protected Account pursuant to the
applicable Servicing Agreements.

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

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

         The Trustee shall execute and deliver to the 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 Servicer or the Master Servicer to assure such continuing treatment.
In particular, the Trustee shall not (a) sell or permit the sale of all or any
portion of the Mortgage Loans or of any investment of deposits in an Account
unless such sale is as a result of a repurchase of the Mortgage Loans pursuant
to this Agreement or the Trustee has received a REMIC Opinion prepared at the
expense of the Trust Fund; and (b) other than with respect to a substitution
pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of this
Agreement, as applicable, accept any contribution to any REMIC after the Startup
Day without receipt of a REMIC Opinion.

         Section 3.03. Monitoring of Servicer. (a) The Master Servicer shall be
responsible for reporting to the Trustee and the Seller the compliance by the
Servicer with its duties under the related Servicing Agreement. In the review of
the Servicer'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 the related Servicing Agreement. In the event that the Master Servicer,
in its judgment, determines that the 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 the Servicer under the
related Servicing Agreement, and shall, in the event that the Servicer fails to
perform its obligations in accordance with the related Servicing Agreement,
subject to the preceding paragraph, terminate the rights and obligations of such
Servicer thereunder and act as servicer of the related Mortgage Loans or to
cause the Trustee to enter in to a new Servicing Agreement with a successor
Servicer selected by the Master Servicer; provided, however, it is understood
and acknowledged by the parties hereto that there will be a period of transition
(not to exceed 90 days) before the actual servicing functions can be fully
transferred to such successor Servicer. Such enforcement, including, without
limitation, the legal prosecution of claims, termination of Servicing Agreements
and the pursuit of other appropriate remedies, shall be in such form and carried
out to such an extent and at such time as the Master Servicer, in its good faith
business judgment, would require were it the owner of the related Mortgage
Loans. The Master Servicer shall pay the costs of such enforcement at its own
expense, provided that the Master Servicer shall not be required to prosecute or
defend any legal action except to the extent that the Master Servicer shall have
received reasonable indemnity for its costs and expenses in pursuing such
action.

         (c) To the extent that the costs and expenses of the Master Servicer
related to any termination of the 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 the Servicer and (ii) all costs and expenses associated with the
complete transfer of servicing, including

                                      -40-
<PAGE>

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

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

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

         Section 3.04. Fidelity Bond. The Master Servicer, at its expense, shall
maintain in effect a blanket fidelity bond and an errors and omissions insurance
policy, affording coverage with respect to all directors, officers, employees
and other Persons acting on such Master Servicer's behalf, and covering errors
and omissions in the performance of the Master Servicer's obligations hereunder.
The amount of coverage to be maintained by the Master Servicer with respect to
the blanket fidelity bond policy shall be $50,000,000 per occurrence, and, with
respect to the errors and omissions insurance policy, shall be $20,000,000 per
occurrence.

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

                                      -41-
<PAGE>

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 the 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
Servicer 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 the 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 Servicer pursuant to Section 4.01 or by the
Servicer pursuant to the related Servicing Agreement have been or will be so
deposited) and shall request that the Custodian, on behalf of the Trustee,
deliver to the Servicer the related Mortgage File. Upon receipt of such
certification and request, the Custodian, on behalf of the Trustee, shall
promptly release the related Mortgage File to the Servicer and the Trustee and
Custodian shall have no further responsibility with regard to such Mortgage
File. Upon any such payment in full, the Servicer is authorized, to give, as
agent for the Trustee, as the mortgagee under the Mortgage that secured the
Mortgage Loan, an instrument of satisfaction (or assignment of mortgage without
recourse) regarding the Mortgaged Property subject to the Mortgage, which
instrument of satisfaction or assignment, as the case may be, shall be delivered
to the Person or Persons entitled thereto against receipt therefor of such
payment, it being understood and agreed that no expenses incurred in connection
with such instrument of satisfaction or assignment, as the case may be, shall be
chargeable to the Protected Account.

         (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan and in accordance with the applicable Servicing
Agreement, the Trustee shall execute such

                                      -42-
<PAGE>

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

         Section  3.08.    Documents, Records and Funds in Possession of Master
Servicer To Be Held for Trustee.

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

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

                                      -43-
<PAGE>

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

         Section  3.09.    Standard Hazard Insurance and Flood Insurance
                           Policies.

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

         (b) Pursuant to Section 4.01, any amounts collected by the Servicer or
the Master 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 Distribution Account, subject
to withdrawal pursuant to Section 4.03. Any cost incurred by the Master Servicer
or the 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 the Servicer pursuant to Sections 4.01 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 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 the Servicer and
remitted to the Master Servicer) in respect of such policies, bonds or contracts
shall be promptly deposited in the Distribution Account upon receipt, except
that any amounts realized that are to be applied to the repair or restoration of
the related Mortgaged Property as a condition precedent to the presentation of
claims on the related Mortgage Loan to the insurer under any applicable
Insurance Policy need not be so deposited (or remitted).

         Section  3.11.  Maintenance of the Primary Mortgage Insurance Policies.

         (a) The Master Servicer shall not take, or permit the 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 the Servicer (to the extent
required under the related Servicing Agreement) to keep in force and effect (to
the extent that the Mortgage Loan requires the Mortgagor to maintain such
insurance), primary mortgage insurance applicable to each

                                      -44-
<PAGE>

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

         (b) The Master Servicer agrees to present, or to cause the Servicer (to
the extent required under the related Servicing Agreement) to present, on behalf
of the Trustee and the Certificateholders, claims to the insurer under any
Primary Mortgage Insurance Policies and, in this regard, to take such reasonable
action as shall be necessary to permit recovery under any Primary Mortgage
Insurance Policies respecting defaulted Mortgage Loans. Pursuant to Section
4.02, any amounts collected by the Master Servicer or the Servicer under any
Primary Mortgage Insurance Policies shall be deposited in the Distribution
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 the Servicer (to the extent required under the related
Servicing Agreement) to foreclose upon, repossess or otherwise comparably
convert the ownership of Mortgaged Properties securing such of the Mortgage
Loans as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments, all in
accordance with the applicable Servicing Agreement.

         Section  3.14.    Compensation for the Master Servicer.

         The Master Servicer will be entitled to all income and gain realized
from any investment of funds in the Distribution Account (the "Master Servicing
Compensation"). 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 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 the Servicer in
connection with a Principal Prepayment in full

                                      -45-
<PAGE>

or otherwise in excess of amounts required to be remitted to the Distribution
Account. The Master Servicer shall be required to pay all expenses incurred by
it in connection with its activities hereunder and shall not be entitled to
reimbursement therefor except as provided in this Agreement.

         Section  3.15.    REO Property.

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

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

         (c) The Master Servicer and the 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 Master Servicing Compensation, 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
Master Servicing Compensation, Servicing Fees may be reimbursed or paid, as the
case may be, prior to final disposition, out of any net rental income or other
net amounts derived from such REO Property.

         (d) To the extent provided in the related Servicing Agreement, the
Liquidation Proceeds from the final disposition of the REO Property, net of any
payment to the Master Servicer and the 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 Distribution
Account on the next succeeding Servicer Remittance Date.

         Section  3.16.    Annual Officer's Certificate as to Compliance.

         (a) The Master Servicer shall deliver to the Trustee and the Rating
Agencies on or before August 30 of each year, commencing on August 30, 2003, 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

                                      -46-
<PAGE>

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 the Servicer
has failed to perform any of its duties, responsibilities and obligations under
its Servicing Agreement in all material respects throughout such year, or, if
there has been a material default in the performance or fulfillment of any such
duties, responsibilities or obligations, specifying each such default known to
such Servicing Officer and the nature and status thereof.

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

         Section 3.17. Annual Independent Accountant's Servicing Report. If the
Master Servicer has, during the course of any fiscal year, directly serviced any
of the Mortgage Loans, then the Master Servicer at its expense shall cause a
nationally recognized firm of independent certified public accountants to
furnish a statement to the Trustee, the Rating Agencies and the Seller on or
before August 30 of each year, commencing on August 30, 2003 to the effect that,
with respect to the most recently ended fiscal year, such firm has examined
certain records and documents relating to the Master Servicer's performance of
its servicing obligations under this Agreement and pooling and servicing and
trust agreements in material respects similar to this Agreement and to each
other and that, on the basis of such examination conducted substantially in
compliance with the audit program for mortgages serviced for Freddie Mac or the
Uniform Single Attestation Program for Mortgage Bankers, such firm is of the
opinion that the Master Servicer's activities have been conducted in compliance
with this Agreement, or that such examination has disclosed no material items of
noncompliance except for (i) such exceptions as such firm believes to be
immaterial, (ii) such other exceptions as are set forth in such statement and
(iii) such exceptions that the Uniform Single Attestation Program for Mortgage
Bankers or the Audit Program for Mortgages Serviced by Freddie Mac requires it
to report. Copies of such statements shall be provided to any Certificateholder
upon request by the Master Servicer, or by the Trustee at the expense of the
Master Servicer if the Master Servicer shall fail to provide such copies. If
such report discloses exceptions that are material, the Master Servicer shall
advise the Trustee whether such exceptions have been or are susceptible of cure,
and will take prompt action to do so.

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

                                      -47-
<PAGE>

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

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

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

         Section  3.21.    Optional Purchase of Defaulted Mortgage Loans.

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

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

                                    Accounts

         Section 4.01. Protected Accounts. (a) The Master Servicer shall enforce
the obligation of the Servicer to establish and maintain a Protected Account in
accordance with the applicable Servicing Agreement, with records to be kept with
respect thereto on a Mortgage Loan by Mortgage Loan basis, into which accounts
shall be deposited within 48 hours (or as of such other time specified in the
related Servicing Agreement) of receipt all collections of principal and
interest on any Mortgage Loan and with respect to any REO Property received by
the Servicer, including Principal Prepayments, Insurance Proceeds, Liquidation
Proceeds, and advances made from the Servicer's own funds (less servicing
compensation as permitted by the applicable Servicing Agreement) and all other
amounts to be deposited in the Protected Account. The Servicer is hereby
authorized to make withdrawals from and deposits to the related Protected
Account for purposes required or permitted by this Agreement. To the extent
provided in the related Servicing Agreement, the Protected Account shall be held
in a Designated Depository Institution and segregated on the books of such
institution in the name of the Trustee for the benefit of Certificateholders.

         (b) To the extent provided in the related Servicing Agreement, amounts

Permitted Investments to mature, or to be subject to redemption or withdrawal,
no later than the date on which such funds are required to be withdrawn for
deposit in the Distribution Account, and shall be held until required for such
deposit. The income earned from Permitted Investments made pursuant to this
Section 4.01 shall be paid to the Servicer under the applicable Servicing
Agreement, and the risk of loss of moneys required to be distributed to the
Certificateholders resulting from such investments shall be borne by and be the
risk of the Servicer. The Servicer (to the extent provided in the Servicing
Agreement) shall deposit the amount of any such loss in the Protected Account
within two Business Days of receipt of notification of such loss but not later
than the second Business Day prior to the Distribution Date on which the moneys
so invested are required to be distributed to the Certificateholders.

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

                  (i) Scheduled Payments on the Mortgage Loans received or any
         related portion thereof advanced by the Servicer pursuant to the
         Servicing Agreements which were due on or before the related Due Date,
         net of the amount thereof comprising the Servicing Fees;

                  (ii) Full Principal Prepayments and any Liquidation Proceeds
         received by the Servicer with respect to such Mortgage Loans in the
         related Prepayment Period, with interest

                                      -49-
<PAGE>

         to the date of prepayment or liquidation, net of the amount thereof
         comprising the Servicing Fees;

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

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

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

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

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

         (c) The Distribution Account shall constitute a trust account of the
Trust Fund segregated on the books of the Trustee and held by the Trustee in
trust in its Corporate Trust Office. The Distribution Account shall be an
Eligible Account. The amount at any time credited to the Distribution Account
shall be (i) 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 to time shall be for the account of the Master
Servicer. The Master Servicer shall be permitted to withdraw or receive
distribution of any and all investment earnings from the Distribution Account on
each Distribution Date. If there is any loss on a Permitted Investment or demand
deposit, the Master Servicer shall remit the amount of the loss to the Trustee
who shall deposit such amount in the Distribution Account. With respect to the
Distribution Account and the funds deposited therein, the Master Servicer shall
take such action as may be necessary to ensure that the Certificateholders shall
be entitled to the priorities afforded to such a trust account (in addition to a
claim against the estate of the Trustee) as provided by 12 U.S.C. ss. 92a(e),
and applicable regulations pursuant thereto, if applicable, or any applicable
comparable state statute applicable to state chartered banking corporations.

         the Master Servicer or the Servicer from Liquidation Proceeds from a
         particular Mortgage Loan for Liquidation Expenses incurred with respect
         to such Mortgage Loan; provided that the Master Servicer shall not be
         entitled to reimbursement for Liquidation Expenses with respect to a
         Mortgage Loan to the extent that (i) any amounts with respect to such
         Mortgage Loan were paid as Excess Liquidation Proceeds pursuant to
         clause (xi) of this Subsection 4.03 (a) to the Master Servicer; and

         recoveries of the payments for which such advances were made;

                  (vii) to reimburse the Master Servicer or the Servicer for any

         Section  4.04.    Pre-Funding Account.

         (a) No later than the Closing Date, the Trustee shall establish and
maintain a segregated trust account, which shall be titled "Pre-Funding Account,
Bank One, National Association, as trustee for the registered holders of
Structured Asset Mortgage Investments Inc., Mortgage Pass- Through Certificates,
Series 2002-AR3" (the "Pre-Funding Account"). The Pre-Funding Account shall be
an Eligible Account. The Trustee shall, promptly upon receipt, deposit in the
Pre-Funding Account and retain therein the Pre-Funded Amount remitted on the
Closing Date to the Trustee by the Seller. Funds deposited in the Pre-Funding
Account shall be held in trust by the Trustee for the Certificateholders for the
uses and purposes set forth herein.

         (b) The Trustee will invest funds deposited in the Pre-Funding Account
as directed by the Seller or its designee in writing in Permitted Investments
with a maturity date (i) no later than

                                      -52-
<PAGE>

the Business Day immediately preceding the date on which such funds are required
to be withdrawn from such account pursuant to this Agreement, if a Person other
than the Trustee or an Affiliate manages or advises such investment, (ii) no
later than the date on which such funds are required to be withdrawn from such
account pursuant to this Agreement, if the Trustee or an Affiliate manages or
advises such investment or (iii) within one (1) Business Day of the Trustee's
receipt thereof. For federal income tax purposes, the Seller or its designee
shall be the owner of the Pre-Funding Account and shall report all items of
income, deduction, gain or loss arising therefrom. All income and gain realized
from investment of funds deposited in the Pre-Funding Account shall be
transferred to the Interest Coverage Account at the following times: (i) on the
Business Day immediately preceding each Distribution Date, if a Person other
than the Trustee or an Affiliate of the Trustee manages or advises such
investment, or on each Distribution Date, if the Trustee or an Affiliate of the
Trustee manages or advises such investment, (ii) on the Business Day immediately
preceding each Subsequent Transfer Date, if a Person other than the Trustee or
an Affiliate of the Trustee manages or advises such investment, or on each
Subsequent Transfer Date, if the Trustee or an Affiliate of the Trustee manages
or advises such investment or (iii) within one (1) Business Day of the Trustee's
receipt thereof. Such transferred funds shall not constitute income and gain for
purposes of Section 4.07(b) hereof. The Seller or its designee shall deposit in
the Pre-Funding Account the amount of any net loss incurred in respect of any
such Permitted Investment immediately upon realization of such loss without any
right of reimbursement therefor. At no time will the Pre-Funding Account be an
asset of any REMIC created hereunder.

         (c)      Amounts on deposit in the Pre-Funding Account shall be
withdrawn by the Trustee as follows:

                  (i) On any Subsequent Transfer Date, the Trustee shall
withdraw from the Pre- Funding Account an amount equal to 100% of the Scheduled
Principal Balances of the Subsequent Mortgage Loans transferred and assigned to
the Trustee for deposit in the mortgage pool on such Subsequent Transfer Date
and pay such amount to or upon the order of the Seller upon satisfaction of the
conditions set forth in Section 2.07 with respect to such transfer and
assignment;

                  (ii) If the amount on deposit in the Pre-Funding Account
(exclusive of investment income) has not been reduced to zero during the
Pre-Funding Period, on the day immediately following the termination of the
Pre-Funding Period, the Trustee shall deposit into the Distribution Account any
amounts remaining in the Pre-Funding Account (exclusive of investment income)
for distribution in accordance with the terms hereof;

                  (iii) To withdraw any amount not required to be deposited
in the Pre-Funding Account or deposited therein in error; and

                  (iv) To clear and terminate the Pre-Funding Account upon the
earlier to occur of (A) the Distribution Date immediately following the end of
the Pre-Funding Period and (B) the termination of this Agreement, with any
amounts remaining on deposit therein being paid to the Certificateholders then
entitled to distributions in respect of principal.

         Withdrawals pursuant to clauses (i), (ii) and (iii) shall be treated as
contributions of cash to REMIC I on the date of withdrawal.

         Section  4.05.    Interest Coverage Account.

         (a) No later than the Closing Date, the Trustee shall establish and
maintain a segregated trust account, which shall be titled "Interest Coverage
Account, Bank One, National Association, as trustee for the registered holders
of Structured Asset Mortgage Investments Inc., Mortgage Pass- Through
Certificates, Series 2002-AR3" (the "Interest Coverage Account"). The Interest
Coverage Account shall be an Eligible Account. The Trustee shall, promptly upon
receipt, deposit in the Interest Coverage Account and retain therein the
Interest Coverage Amount remitted on the Closing Date to the Trustee by the
Seller. Funds deposited in the Interest Coverage Account shall be held in trust
by the Trustee for the Certificateholders for the uses and purposes set forth
herein.

         (b) For federal income tax purposes, the Class X Certificateholders
shall be the owner of the Interest Coverage Account and shall report all items
of income, deduction, gain or loss arising therefrom. At no time will the
Interest Coverage Account be an asset of any REMIC created hereunder. All income
and gain realized from investment of funds deposited in the Interest Coverage
Account, which investment shall be made solely upon the written direction of the
Class X Certificateholders, shall be for the sole and exclusive benefit of the
Class X Certificateholders and shall be remitted by the Trustee to the Class X
Certificateholders no later than the first Business Day following receipt of
such income and gain by the Trustee. The Class X Certificateholders shall
deposit in the Interest Coverage Account the amount of any net loss incurred in
respect of any such Permitted Investment immediately upon realization of such
loss.

         (c) On each Distribution Date during the Pre-Funding Period and on the
Distribution Date immediately following the end of the Pre-Funding Period, the
Trustee shall withdraw from the Interest Coverage Account and deposit in the
Distribution Account an amount equal to 30 days' interest on the excess, if any,
of the Pre-Funded Amount over the aggregate Scheduled Principal Balance of
Subsequent Mortgage Loans that both (i) had a Due Date during the Due Period
relating to such Distribution Date and (ii) had a Subsequent Cut-off Date prior
to the first day of the month in which such Distribution Date occurs, at a per
annum rate equal to the weighted average of the Net Mortgage Rates of those
Subsequent Mortgage Loans. Such withdrawal and deposit shall be treated as a
contribution of cash by the Mortgage Loan Seller to REMIC I on the date thereof.
Immediately following any such withdrawal and deposit, and immediately following
the conveyance of any Subsequent Mortgage Loans to the Trust on any Subsequent
Transfer Date, the Trustee shall withdraw from the Interest Coverage Account and
remit to the Mortgage Loan Seller or its designee an amount equal to the excess,
if any, of the amount remaining in such Interest Coverage Account over the
amount that would be required to be withdrawn therefrom (assuming sufficient
funds therein) pursuant to the preceding sentence on each subsequent
Distribution Date, if any, that will occur during the Pre-Funding Period or that
will be the Distribution Date immediately following the end of the Pre-Funding
Period, if no Subsequent Mortgage Loans were acquired by the Trust Fund after
the end of the Prepayment Period relating to the current Distribution Date.

         (d) Upon the earliest of (i) the Distribution Date immediately
following the end of the Pre-Funding Period, (ii) the reduction of the principal
balances of the Certificates to zero or (iii) the termination of this Agreement
in accordance with Section 10.01, any amount remaining on deposit in the
Interest Coverage Account after distributions pursuant to paragraph (c) above
shall be withdrawn by the Trustee and paid to the Seller or its designee.

         Section  4.06.    Distribution of Carryover Shortfall Amount; Carryover
Shortfall Reserve Fund.

         (a) On the Closing Date, the Trustee shall establish and maintain in
its name, in trust for the benefit of Class A-1, Class A-2, Class B-1, Class B-2
and Class B-3 Certificates, the Carryover Shortfall Reserve Fund. The Trustee
shall, promptly upon receipt, deposit in the Carryover Shortfall Reserve Fund an
amount equal to $5,000 to be remitted on the Closing Date to the Trustee by the
Mortgage Loan Seller. On each Distribution Date, the Trustee shall transfer from
the Distribution Account to the Carryover Shortfall Reserve Fund the amounts
specified pursuant to Section 5.01(e). On each Distribution Date, to the extent
required, the Trustee shall make withdrawals from the Carryover Shortfall
Reserve Fund and use the amounts in the Carryover Shortfall Reserve Fund to make
distributions to the Class A-1, Class A-2, Class B-1, Class B-2 and Class B-3
Certificates, in an amount equal to the amount of any Carryover Shortfall Amount
on such Certificate. Any such amounts transferred shall be treated for federal
tax purposes as amounts distributed by REMIC II to the Class X
Certificateholders as transferee thereof.

         (b) The Carryover Shortfall Reserve Fund shall be an Eligible Account.
Amounts held in the Carryover Shortfall Reserve Fund from time to time shall
continue to constitute assets of the Trust Fund, but not of the REMICs, until
released from the Carryover Shortfall Reserve Fund pursuant to this Section
4.08. The Carryover Shortfall Reserve Fund constitutes an "outside reserve fund"
within the meaning of Treasury Regulation ss. 1.860G-2(h) and is not an asset of
the REMICs. The Class X Certificateholders shall be the owners of the Carryover
Shortfall Reserve Fund, and for all federal tax purposes, amounts transferred by
the REMICs to the Carryover Shortfall Reserve Fund shall be treated as amounts
distributed by the REMICs to the Class X Certificateholders. The Trustee shall
keep records that accurately reflect the funds on deposit in the Carryover
Shortfall Reserve Fund.

                                  Certificates

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

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

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

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

         (c) (i) REMIC I will be evidenced by (x) the REMIC I Regular Interests

         (f) The Certificates shall be substantially in the forms set forth in
Exhibits A-1, A-2 and A-3. On original issuance, the Trustee shall sign,

countersign 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

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

                                      -60-
<PAGE>

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:

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

         Individual Certificate or Certificates and the Trustee shall register
         such transfer only upon compliance with the provisions of Subsection

                  (ii) In the case of a beneficial interest in a Class of Global

         Individual Certificates of such Class in different authorized

with an executed instrument of assignment and transfer satisfactory in form and
substance to the Trustee in the case of transfer and a written request for
exchange in the case of exchange. The holder of a beneficial interest in a
Global Certificate may, subject to the rules and procedures of the Depository,
cause the Depository (or its nominee) to notify the Trustee in writing of a
request for transfer or exchange of such beneficial interest for an Individual
Certificate or Certificates. Following a proper request for transfer or
exchange, the Trustee shall, within five Business Days of such request made at
such Corporate Trust Office, sign, countersign and deliver at such Corporate
Trust Office, to the transferee (in the case of transfer) or holder (in the case
of exchange) or send by first class mail at the risk of the transferee (in the
case of transfer) or holder (in the case of exchange) to such address as the
transferee or holder, as applicable, may request, an Individual Certificate or
Certificates, as the case may require, for a like aggregate Fractional Undivided
Interest and in such authorized denomination or denominations as may be
requested. The presentation for transfer or exchange of any Individual
Certificate shall not be valid unless made at the Corporate Trust Office by the
registered holder in person, or by a duly authorized attorney-in-fact.

         (i) At the option of the Certificateholders, Certificates may be
exchanged for other Certificates of authorized denominations of a like Class and
aggregate Fractional Undivided Interest, upon surrender of the Certificates to
be exchanged at any such office or agency; PROVIDED, HOWEVER, that no
Certificate may be exchanged for new Certificates unless the original Fractional
Undivided Interest represented by each such new Certificate (i) is at least
equal to the minimum authorized denomination or (ii) is acceptable to the Seller
as indicated to the Trustee in writing. Whenever any

                                      -64-
<PAGE>

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 mutilated, destroyed, lost or stolen Certificate shall thereupon be
canceled of record by the Trustee and shall be of no further effect and evidence
no rights.

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

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

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

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

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

                                      -66-
<PAGE>

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

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

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

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

                                      -67-
<PAGE>

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

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

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

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

                                   ARTICLE VI

                         Payments to Certificateholders

         Section 6.01. Distributions on the Certificates. (a) Interest and
principal on the Certificates will be distributed monthly on each Distribution
Date, commencing in September 2002, in an aggregate amount equal to the
Available Funds for such Distribution Date.

         (A) On each Distribution Date on or prior to the Cross-Over Date, the
Available Funds will be distributed to the Senior Certificates as follows:

                  FIRST, pro rata, to the Senior Certificates, the Accrued
         Certificate Interest on such Classes for such Distribution Date;
         provided, however, that the amount of Accrued Certificate Interest paid
         to the Class X Certificates will be reduced by the aggregate amount of
         any Carryover Shortfall Amounts on the Class A-1, Class A-2, Class B-1,
         Class B-2 and Class B-3 Certificates for that Distribution Date, which
         will be deposited into the Carryover Shortfall Reserve Fund;

                  SECOND, pro rata, to the Senior Certificates, the Accrued
         Certificate Interest thereon pursuant to clause FIRST remaining
         undistributed from previous Distribution Dates, to the extent of
         remaining Available Funds;

                  THIRD, sequentially, in the following order, to the Class R-I
         and Class R-II and Class A-1 Certificates, in reduction of the Current
         Principal Amount thereof, the Senior Optimal Principal Amount for such
         Distribution Date to the extent of remaining Available Funds, in each
         case until the Current Principal Amount of such Class has been reduced
         to zero;

         (B) On each Distribution Date on or prior to the Cross-Over Date, an
amount equal to the remaining Available Funds after the distributions in (A)
above will be distributed to the Class A-2 Certificates, up to an amount equal
to and in the following order: (a) the Accrued Certificate Interest thereon for
such Distribution Date, (b) any Accrued Certificate Interest thereon remaining
undistributed from previous Distribution Dates and (c) such Class's Allocable
Share for such Distribution Date, in each case, to the extent of the remaining
Available Funds;

         (C) On each Distribution Date on or prior to the Cross-Over Date, an
amount equal to the remaining Available Funds after the distributions in (A) and
(B) above will be distributed sequentially, in the following order, to the Class
B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates, in
each case up to an amount equal to and in the following order: (a) the Accrued
Certificate Interest thereon for such Distribution Date, (b) any Accrued
Certificate Interest thereon remaining undistributed from previous Distribution
Dates and (c) such Class's Allocable Share for such Distribution Date, in each
case, to the extent of the remaining Available Funds;

         (b) If, after distributions have been made pursuant to priorities FIRST
and SECOND of clause (A) above on any Distribution Date, the remaining Available
Funds are less than the Senior Optimal Principal Amount, such amount shall be
reduced, and such remaining funds will be distributed on the Senior Certificates
(other than the Class X Certificates) on the basis of such reduced amount.

                                      -69-
<PAGE>

         (c) "PRO RATA" distributions among Classes of Certificates will be made
in proportion to the then Current Principal Amount of such Classes.

         (d) On each Distribution Date, any Available Funds remaining after
payment of interest and principal to the Classes of Certificates entitled
thereto, as described above, will be distributed to the Class R-II Certificates;
provided that if on any Distribution Date there are any Available Funds
remaining after payment of interest and principal to a Class or Classes of
Certificates entitled thereto, such amounts will be distributed to the other
Classes of Senior Certificates (other than the Class X Certificates), pro rata,
based upon their Current Principal Amounts, until all amounts due to all such
Classes of Senior Certificates have been paid in full, before any amounts are
distributed to the Class R-II Certificates. It is not anticipated that there
will be any significant amounts remaining for such distribution.

         (e) On each Distribution Date, any amounts in the Carryover Shortfall
Reserve Fund will be distributed sequentially, in the following order, to the
Class A-1, Class A-2, Class B-1, Class B-2 and Class B-3 Certificates, in each
case up to an amount equal to any Carryover Shortfall Amounts with respect to
such Class of Certificates.

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

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

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

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

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

                                      -70-
<PAGE>

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

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

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

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

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

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

                    SEVENTH, to the Class A-2 Certificates until the Current
                    Principal Amount thereof has been reduced to zero; and

                    EIGHTH, to the Senior Certificates (other than the Interest
                    Only Certificates) on a PRO RATA basis.

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

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

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

         (f) On each Distribution Date, the Trustee shall determine the Senior
Mezzanine Certificate Writedown Amount and the Subordinate Certificate Writedown
Amount. Any such Subordinate Certificate Writedown Amount shall effect a
corresponding reduction in the Current Principal Amount of (i) with respect to
the Subordinate Certificate Writedown Amount, if prior to

                                      -71-
<PAGE>

the Cross-Over Date, the Current Principal Amounts of the Subordinate
Certificates, in the reverse order of their numerical Class designations, (ii)
with respect to the Senior Mezzanine Certificate Writedown Amount, if prior to
the Cross-Over Date, the Current Principal Amounts of the Senior Mezzanine
Certificates and (iii) from and after the Cross-Over Date, the Senior
Certificates which reduction shall occur on such Distribution Date after giving
effect to distributions made on such Distribution Date.

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

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

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

         Section 6.04. Statements to Certificateholders. (a) Concurrently with
each distribution to Certificateholders, the Securities Administrator shall make
available to the parties hereto and each Certificateholder via the Securities
Administrator's internet website as set forth below, the following information,
expressed with respect to clauses (i) through (vii) in the aggregate and as a
Fractional Undivided Interest representing an initial Current Principal Amount
of $1,000, in the case of the Interest Only Certificates, a Notional Amount of
$1,000, or in the case of the Residual Certificates, an initial Current
Principal Amount of $50:

<PAGE>

                    (i) the Current Principal Amount 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 Interest Accrual Period;

                  (iv) any Carryover Shortfall, any Carryover Shortfall Amounts,
         the Net Interest Shortfall and any other adjustments to interest at the
         related Pass-Through Rate necessary to account for any difference
         between interest accrued and aggregate interest distributed with

                    (xvii) the amount of Realized Losses allocated to each Class

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

                                      -74-
<PAGE>

Administrator's customer service desk at (301) 815-6600. Parties that are unable
to use the above distribution option are entitled to have a paper copy mailed to
them via first class mail by calling the customer service desk and indicating
such. The Securities Administrator shall have the right to change the way such
reports are distributed in order to make such distribution more convenient
and/or more accessible to the parties, and the Securities Administrator shall
provide timely and adequate notification to all parties regarding any such
change.

         (b) By August 30 of each year beginning in 2003, the Trustee will
furnish such report to each Holder of the Certificates of record at any time
during the prior calendar year as to the aggregate of amounts reported pursuant
to subclauses (a)(ii) and (a)(v) above with respect to the Certificates, plus
information with respect to the amount of servicing compensation and such other
customary information as the Securities Administrator may determine and advise
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
pursuant to the requirements of the Code.

         Section 6.05. Monthly Advances. Pursuant to the related Servicing
Agreement, the Servicer will make Monthly Advances. Each such Monthly Advance
shall be remitted to the Distribution Account no later than 1:00 p.m. Eastern
time on the Distribution Account Deposit Date in immediately available funds.
Subject to the Master Servicer's recoverability determination, in the event that
the Servicer fails to make a required Advance, the Master Servicer shall be
required to remit the amount of such Monthly Advance to the Distribution
Account. The Master Servicer shall be obligated to make any such Advance only to
the extent that such advance would not be a Nonrecoverable Advance. If the
Master Servicer shall have determined that it has made a Nonrecoverable Advance
or that a proposed Monthly Advance or a lesser portion of such Monthly Advance
would constitute a Nonrecoverable Advance, the Master Servicer shall deliver (i)
to the Trustee for the benefit of the Certificateholders funds constituting the
remaining portion of such Advance, if applicable, and (ii) to the Trustee an
Officer's Certificate setting forth the basis for such determination.

         The Master Servicer shall be entitled to be reimbursed from the
Distribution Account for all Monthly Advances of its own funds made pursuant to
this Section as provided in Section 4.03. The obligation to make Monthly
Advances with respect to any Mortgage Loan shall continue until such Mortgage
Loan is paid in full or the related Mortgaged Property or related REO Property
has been liquidated or until the purchase or repurchase thereof (or substitution
therefor) from the Trust Fund pursuant to any applicable provision of this
Agreement, except as otherwise provided in this Section 6.05.

         Subject to and in accordance with the provisions of Article VIII
hereof, in the event the Master Servicer fails to make such Monthly Advance,
then the Trustee, as Successor Master Servicer, shall be obligated to make such
Monthly Advance, subject to the provisions of this Section 6.05.

         Section 6.06. Compensating Interest Payments. Upon notice timely notice
by the Trustee, the Master Servicer shall deposit in the Distribution Account
not later than each Distribution Account Deposit Date an amount equal to the
lesser of (i) the aggregate amounts required to be paid by the Servicer under
the applicable 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 Servicer 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.

                                   ARTICLE VII

                               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.

         (a) 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.

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

                                      -76-
<PAGE>

resignation or removal of the Trustee, Master Servicer or the Securities
Administrator and the termination of this Agreement.

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

         Section 7.04. Limitations on Liability of the Master Servicer and
Others. Subject to the obligation of the Master Servicer to indemnify the
Indemnified Persons pursuant to Section 7.03:

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

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

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

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

                                      -77-
<PAGE>

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 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 the Servicer, except as otherwise expressly provided herein.

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

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

         Section 7.07. Sale and Assignment of Master Servicing. The Master
Servicer may sell and assign its rights and delegate its duties and obligations
in its entirety as Master Servicer under this Agreement and EMC may terminate
the Master Servicer without cause and select a new Master Servicer; provided,
however, that: (i) the purchaser or transferee accepting such assignment and
delegation (a) shall be a Person which shall be qualified to service mortgage
loans for Fannie Mae or Freddie Mac; (b) shall have a net worth of not less than
$10,000,000 (unless otherwise approved by each Rating Agency pursuant to clause
(ii) below); (c) shall be reasonably satisfactory to the Trustee (as evidenced
in a writing signed by the Trustee); and (d) shall execute and deliver to the
Trustee an agreement, in form and substance reasonably satisfactory to the
Trustee, which contains an assumption by such Person of the due and punctual
performance and observance of each covenant and condition to be performed or
observed by it as master servicer under this Agreement, any custodial agreement
from and after the effective date of such agreement; (ii) each Rating Agency
shall be given prior written notice of the identity of the proposed successor to
the Master Servicer and each Rating Agency's rating of the Certificates in
effect immediately prior to such assignment, sale and delegation will not be
downgraded, qualified or withdrawn as a result of such assignment,

                                      -78-

sale and delegation, as evidenced by a letter to such effect delivered to the
Master Servicer and the Trustee; (iii) the Master Servicer assigning and selling
the master servicing shall deliver to the Trustee an Officer's Certificate and
an Opinion of Independent Counsel, each stating that all conditions precedent to
such action under this Agreement have been completed and such action is
permitted by and complies with the terms of this Agreement; and (iv) in the
event the Master Servicer is terminated without cause by EMC, EMC shall pay the
terminated Master Servicer a termination fee equal to 0.25% of the aggregate
Scheduled Principal Balance of the Mortgage Loans at the time the master
servicing of the Mortgage Loans is transferred to the successor Master Servicer.
No such assignment or delegation shall affect any liability of the Master
Servicer arising prior to the effective date thereof.

                                     Default

         Section 8.01. "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 deposit in the Distribution
         Account any amount so required by it to be deposited pursuant to this
         Agreement, and such failure continues unremedied for a period of three
         Business Days after the date upon which written notice of such failure,
         requiring the same to be remedied, shall have been given to the Master
         Servicer; or

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

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

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

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

                                      -80-

<PAGE>

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

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

                                      -81-

<PAGE>

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

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

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

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

         Section 8.05. List of Certificateholders. Upon written request of three

Certificateholders with respect to their rights under this Agreement, the
Trustee will afford such Certificateholders access during business hours to the
most recent list of Certificateholders held by the Trustee.

                                   ARTICLE IX

             Concerning the Trustee and the Securities Administrator

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

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

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

                                      -84-

<PAGE>

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

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

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

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

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

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

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

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

                                      -85-

<PAGE>

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

         Section 9.02.     Certain Matters Affecting the Trustee and the
Securities Administrator. Except as otherwise provided in Section 9.01:

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

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

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

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

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

                                      -86-

<PAGE>

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

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

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

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

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

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

         Section 9.03. Trustee and Securities Administrator Not Liable for
Certificates or Mortgage Loans. The recitals contained herein and in the
Certificates (other than the signature and countersignature of the Trustee on
the Certificates) shall be taken as the statements of the Seller, and neither
the Trustee nor the Securities Administrator shall have any responsibility for
their correctness. Neither the Trustee nor the Securities Administrator makes
any representation as to the validity or sufficiency of the Certificates (other
than the signature and countersignature of the Trustee

                                      -87-

<PAGE>

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

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

         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. In addition, the
Trustee and the Securities Administrator will be entitled to recover from the
Distribution 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
Certificateholders or the Trust Fund hereunder. If funds in the Distribution
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

                                      -88-

<PAGE>

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 S&P with
respect to their long-term rating and rated "BBB" or higher by S&P 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.

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.

         (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

                                      -89-

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.

         (d) No resignation or removal of the Trustee or the Securities
Administrator and appointment of a successor Trustee or Securities Administrator
pursuant to any of the provisions of this Section 9.08 shall become effective
except upon appointment of and acceptance of such appointment by the successor
Trustee or Securities Administrator as provided in Section 9.09.

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

                                      -91-

<PAGE>

either jointly with the Trustee or separately, as may be provided therein,
subject to all the provisions of this Agreement, specifically including every
provision of this Agreement relating to the conduct of, affecting the liability
of, or affording protection to, the Trustee. Every such instrument shall be
filed with the Trustee.

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

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

         Section 9.12. Federal Information Returns and Reports to
Certificateholders; REMIC Administration. (a) For federal income tax purposes,
the taxable year of each of REMIC I and REMIC II shall be a calendar year and
the Securities Administrator shall maintain or cause the maintenance of the
books of each such REMIC on the accrual method of accounting.

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

                                      -92-

<PAGE>

Securities Administrator does not own any such Residual Certificate. In the
event that the Code or applicable Treasury regulations prohibit the Trustee from
signing tax or information returns or other statements, or the Securities
Administrator from acting as agent for the Tax Matters Person, the Trustee and
the Securities Administrator shall take whatever action that in its sole good
faith judgment is necessary for the proper filing of such information returns or
for the provision of a tax matters person, including designation of the Holder
of a Residual Certificate to sign such returns or act as tax matters person.
Each Holder of a Residual Certificate shall be bound by this Section.

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

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

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

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

                                   Termination

         Section 10.01. Termination Upon Repurchase by the Seller or its
Designee or Liquidation of the Mortgage Loans. (a) Subject to Section 10.02, the
respective obligations and responsibilities of the Seller, the Trustee, the
Master Servicer and the Securities Administrator created hereby, other than the
obligation of the Trustee to make payments to Certificateholders as hereinafter
set forth shall terminate upon:

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

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

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

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

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

                                      -94-

<PAGE>

above, the Seller may elect to terminate the REMIC I or REMIC II at any time,
and upon such election, the Seller or its designee, shall repurchase all the
Mortgage Loans.

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

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

         (f) Upon the presentation and surrender of the Certificates, the
Trustee shall distribute to the remaining Certificateholders, in accordance with
their respective interests, all distributable amounts remaining in the
Distribution Account. Upon deposit by the Master Servicer of such distributable
amounts, and following such final Distribution Date, the Trustee shall release
promptly to the Seller or its designee the Mortgage Files for the remaining
Mortgage Loans, and the

                                      -95-

<PAGE>

Distribution Account shall terminate, subject to the Trustee's obligation to
hold any amounts payable to the Certificateholders in trust without interest
pending final distributions pursuant to this Subsection 10.01(g).

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

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

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

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

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

         (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 which shall be provided to the Trustee other
than at the Trustee's expense. Notwithstanding any other provision of this
Agreement, for purposes of the giving or withholding of consents pursuant to
Section 11.02(b), Certificates registered in the name of or held for the benefit
of the Seller, the Securities Administrator, the Master Servicer, or the Trustee
or any Affiliate thereof shall be entitled to vote their Fractional Undivided
Interests with respect to matters affecting such Certificates.

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

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

                                      -97-

<PAGE>

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

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

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

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

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

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

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

                                      -98-

<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 Seller, the Securities Administrator, 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,

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

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

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

                                      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"), EMC Mortgage
Corporation, Wells Fargo, as Master Servicer and securities administrator and
Bank One, National Association, as trustee (the "Trustee"), a summary of certain
of the pertinent provisions of which is set forth hereafter. To the extent not
defined herein, capitalized terms used herein shall have the meaning ascribed to
them in the Agreement. This Certificate is issued under and is subject to the
terms, provisions and conditions of the Agreement, to which Agreement the Holder
of this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the [Current Principal] [Notional] Amount [of each Component] hereof at a per
annum rate equal to the Pass-Through Rate set forth above. The Trustee will
distribute on the 19th day of each month, or, if such 19th 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 calendar month preceding the month of such Distribution
Date, an amount equal to the product of the Fractional Undivided Interest
evidenced by this Certificate and the amount (of interest and principal, if any)
required to be distributed to the Holders of Certificates of the same Class as
this Certificate. The Assumed Final Distribution Date is the first Distribution
Date in the month immediately following the month of the latest scheduled
maturity date of any Mortgage Loan and is not likely to be the date on which the
[Current Principal] [Notional] Amount of this Class of Certificates will be
reduced to zero.

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

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

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

of rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

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

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

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

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

                  The obligations created by the Agreement and the Trust Fund
created thereby (other than the obligations to make payments to
Certificateholders with respect to the termination of the Agreement) shall
terminate upon the earlier of (i) the later of the (A) final payment or other
liquidation (or Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund and (B) disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and the
remittance of all funds due under the Agreement, or (ii) the optional repurchase
by the party named in the Agreement of all the Mortgage Loans and other assets
of the Trust Fund in accordance with the terms of the Agreement. Such optional
repurchase may be made only on or after the Distribution Date on which the
aggregate unpaid principal balance of the

                                      A-1-4

<PAGE>

Mortgage Loans is less than the percentage of the aggregate Outstanding
Principal Balance specified in the Agreement of the Mortgage Loans at the
Cut-off Date. The exercise of such right will effect the early retirement of the
Certificates. In no event, however, will the Trust Fund created by the Agreement
continue beyond the expiration of 21 years after the death of certain persons
identified in the Agreement.

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

                                 SERIES 2002-AR3

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

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

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

                                      A-2-3

<PAGE>

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"),
EMC Mortgage Corporation, Wells Fargo, as Master Servicer and securities
administrator and Bank One, National Association, as trustee (the "Trustee"), a
summary of certain of the pertinent provisions of which is set forth hereafter.
To the extent not defined herein, capitalized terms used herein shall have the
meaning ascribed to them in the Agreement. This Certificate is issued under and
is subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of its acceptance hereof
assents and by which such Holder is bound.

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Current Principal Amount hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Trustee will distribute on the 19th day
of each month, or, if such 19th 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 calendar
month preceding the month of such Distribution Date, an amount equal to the
product of the Fractional Undivided Interest evidenced by this Certificate and
the amount (of interest and principal, if any) required to be distributed to the
Holders of Certificates of the same Class as this Certificate. The Assumed Final
Distribution Date is the first Distribution Date in the month immediately
following the month of the latest scheduled maturity date of any Mortgage Loan
and is not likely to be the date on which the Current Principal Amount of this
Class of Certificates will be reduced to zero.

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

                  [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 is to be made, (i) the Trustee or the Seller may
require an opinion of counsel acceptable to and in form and substance
satisfactory to the Trustee and the Seller that such transfer is exempt
(describing the applicable exemption and the basis therefor) from or is being
made pursuant to the registration requirements of the Securities Act of 1933, as
amended, and of any applicable statute of any state and (ii) the transferor and
the transferee shall execute an investment letter in the form described by

                                      A-2-4

<PAGE>

Section 5.06(a) of the Agreement. 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, EMC 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.]

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

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

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

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

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

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

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

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

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

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

                                 SERIES 2002-AR3

         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 one- to four-family adjustable
         interest rate mortgage loans sold by STRUCTURED ASSET MORTGAGE
         INVESTMENTS INC.

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

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

                                      A-3-3

<PAGE>

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

                  Interest on this Certificate will accrue during the month
prior to the month in which a Distribution Date (as hereinafter defined) occurs
on the Current Principal Amount hereof at a per annum rate equal to the
Pass-Through Rate set forth above. The Trustee will distribute on the 19th day
of each month, or, if such 19th 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 calendar
month preceding the month of such Distribution Date, an amount equal to the
product of the Fractional Undivided Interest evidenced by this Certificate and
the amount (of interest and principal, if any) required to be distributed to the
Holders of Certificates of the same Class as this Certificate. The Assumed Final
Distribution Date is the first Distribution Date in the month immediately
following the month of the latest scheduled maturity date of any Mortgage Loan
and is not likely to be the date on which the Current Principal Amount of this
Class of Certificates will be reduced to zero.

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

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

                                      A-3-4

<PAGE>

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

                  This certificate may not be acquired directly or indirectly
by, or on behalf of, an employee benefit plan or other retirement arrangement
which is subject to title I of the Employee Retirement Income Security Act of
1974, as amended, and/or section 4975 of the Internal Revenue Code of 1986, as
amended.

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

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

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

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

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

                  The Certificates are issuable only as registered Certificates
without coupons in the Classes and denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
this Certificate is exchangeable for one or more new

                                      A-3-5

<PAGE>

Certificates evidencing the same Class and in the same aggregate Fractional
Undivided Interest, as requested by the Holder surrendering the same.

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

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

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

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

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

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

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

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

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

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 then contained in the Mortgage Files.

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

                  Section 2.5 Custodian to Cooperate: Release of Mortgage Files.
Upon receipt of written notice from the Trustee that the Mortgage Loan Seller
has repurchased a Mortgage Loan pursuant to Article II of the Pooling and
Servicing Agreement, and that the purchase price therefore has been deposited in
the Distribution Account, then the Custodian agrees to promptly release to the
Mortgage Loan Seller the related Mortgage File.

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

                  From time to time as is appropriate for the servicing or
foreclosure of any Mortgage Loan, including, for this purpose, collection under
any Primary Insurance Policy, the related Servicer shall deliver to the
Custodian a Request for Release signed by a Servicing Officer requesting that
possession of all of the Mortgage File be released to the related Servicer and
certifying as to the reason for such release and that such release will not
invalidate any insurance coverage provided in respect of the Mortgage Loan under
any of the Insurance Policies. Upon receipt of the foregoing, the Custodian
shall deliver the Mortgage File to the related Servicer. The related Servicer
shall cause each Mortgage File or any document therein so released to be
returned to the Custodian when the need therefor by the related Servicer no
longer exists, unless (i) the Mortgage Loan has been liquidated and the
Liquidation Proceeds relating to the Mortgage Loan have been deposited in the
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.

<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, from the Trustee
to the Mortgage Loan Seller and the related Mortgage Note shall be endorsed
without recourse by the Trustee and be returned to the Mortgage Loan Seller. In
connection with any Request for Release of a Mortgage File because of the
payment in full of a Mortgage Loan, such Request for Release shall be
accompanied by a certificate of satisfaction or other similar instrument to be
executed by or on behalf of the Trustee and returned to the related Servicer.
                  Section 2.6 Assumption Agreements. In the event that any
assumption agreement, 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 a Bailee and Agent of the Trustee. With
respect to each Mortgage Note, Mortgage and other documents constituting each
Mortgage File which are delivered to the Custodian, the Custodian is exclusively
the bailee and agent of the Trustee and has no instructions to hold any Mortgage
Note or Mortgage for the benefit of any person other than the Trustee and the
Certificateholders and undertakes to perform such duties and only such duties as
are specifically set forth in this Agreement. Except upon compliance with the
provisions of Section 2.5 of this Agreement, no Mortgage Note, Mortgage or
Mortgage File shall be delivered by the Custodian to the Company, the Servicers
or the Master Servicer or otherwise released from the possession of the
Custodian.

                  Section 3.2   Reserved.

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

                  Section 3.4 Master Servicer to Pay Custodian's Fees and
Expenses. The Master Servicer covenants and agrees to pay to the Custodian from
time to time, and the Custodian shall be entitled to, reasonable compensation
for all services rendered by it in the exercise and performance of any of the
powers and duties hereunder of the Custodian, and the Master Servicer will pay
or reimburse the Custodian upon its request for all reasonable expenses,
disbursements and advances

                                       G-4

<PAGE>

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.

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

                            MISCELLANEOUS PROVISIONS

                  Section 4.1 Notices. All notices, requests, consents and
demands and other communications required under this Agreement or pursuant to
any other instrument or document delivered hereunder shall be in writing and,
unless otherwise specifically provided, may be delivered personally, by telegram
or telex, or by registered or certified mail, postage prepaid, return receipt
requested, at the addresses specified on the signature page hereof (unless
changed by the particular party whose address is stated herein by similar notice
in writing), in which case the notice will be deemed delivered when received.

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

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

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

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

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

Administrator, EMC Mortgage Corporation and the Trustee as trustee, the Seller
and the Trustee agree to the sale by the Seller and the purchase by the Trustee
in trust, on behalf of the Trust, of the Subsequent Mortgage Loans listed on the
Schedule of Mortgage Loans attached to the Instrument as Exhibit 1 hereto (the

                           Section 1. Conveyance of Subsequent Mortgage Loans.

                           (a)  The Seller does hereby sell, transfer, assign,

delivery hereof, does hereby transfer, assign, set over and otherwise convey to

all of the properties subject to the Mortgages are situated, and in any other
appropriate public recording office or elsewhere, such recordation to be

                           This Instrument may be executed in one or more
counterparts and by the different parties hereto on separate counterparts, each
of which, when so executed, shall be deemed to be an original; such
counterparts, together, shall constitute one and the same instrument.

                           Section 6.       Successors and Assigns.
